+### Why is the Firebase OSSU app different/broken?
+(#why-is-the-Firebase-OSSU-app-different-broken)
+
+The OSSU curriculum and ecosystem have been collaboratively built by many individuals. The Firebase app was one such contribution. When it was written, it was with the intention of helping future OSSU students.
+
+Unfortunately, the app has not been updated in many years. It does not reflect updates to the curriculum, it contains links to courses that no longer exist, and it has known bugs that prevent students from loggining in.
+
+It is our hope that the creators of the Firebase app can bring the app up to date. Until that time, the firebase app should be considered a deprecated product that is no longer supported.

Subject: [PATCH 005/306] Remove cryptography from Core Applications
Closes #570
Removing, as the course is too in depth on cryptography without teaching other important areas of security.
CS2013 specifies that the undergraduate CS curriculum include the Knowledge Area Information Assurance and Security (IAS). This knowledge area includes an introduction to cryptography. But unless students take an elective course in Cryptography, they need only demonstrate a familiarity with the topic, vocabulary, the use of primes in cryptography and how public keys are used.
As pointed out by @MohamedMandouh, this course is an advanced class offered at Stanford.
Meanwhile, IAS specifies a number of other important topics, which this class does not address.

Unfortunately, the app has not been updated in many years. It does not reflect updates to the curriculum, it contains links to courses that no longer exist, and it has known bugs that prevent students from loggining in.
It is our hope that the creators of the Firebase app can bring the app up to date. Until that time, the firebase app should be considered a deprecated product that is no longer supported.

+### What is a good course to learn this particular language?
+OSSU focuses on finding the best courses to learn computer science topics, and isn’t focused on finding language specific courses. If you are looking to learn a particular language or framework there are two great resources to check.
+1. [Hackr.io](https://hackr.io/) allows users to submit and upvote learning resources for topics such as Python or the Java Spring Framework.
+2. Most languages have a community on reddit. When you find the community’s page, check to see if there is a wiki or sidebar with resources. For example, see [/r/python](https://old.reddit.com/r/Python). Note that the sidebar content can be different depending on whether you use www.reddit.com or old.reddit.com.

## Substantive changes
If you have specific and substantive criticisms of the curriculum, i.e. problems related to the progression/content of courses it would be appropriate to [open an issue](https://help.github.com/articles/creating-an-issue/). While it is acceptable to point out problems, all successful changes naturally require a plan for fixing the problem.
OSSU’s curricular guidelines are [here](https://github.com/ossu/computer-science/blob/master/extras/curriculum_guidelines.md). Successful critiques of the curriculum will point out ways that OSSU is failing to uphold these guidelines. Examples are:
-OSSU lists a course as required when the course topics are elective in the curricular guide.
-OSSU does not having a course to cover required topics from the curricular guide.
-OSSU lists multiple courses that cover the same topics when fewer courses could suffice.
-OSSU recommends a course to teach a topic, but there exists a higher quality course that covers the same material.

+## Other ways to contribute
+### Responding to Issues
Issues require more than just users to suggest them. Issues require active community members to read and respond to proposals. Even adding simple [emoji reactions](https://github.blog/2016-03-10-add-reactions-to-pull-requests-issues-and-comments/) can help the community.
+### Engaging with other students
+Learning is enhanced by engaged peers. You can be that peer for someone new to OSSU. When you see a new person posting in Gitter, ask them a question about themselves. When you see a cohort starting at _almost_ the right time, join in. Doing so will make OSSU a stronger program for everyone, including you.

- [Advanced CS](#advanced-cs) assumes the student has already taken the entirety of Core CS
and is knowledgeable enough now to decide which electives to take.
- Note that [Advanced systems](#advanced-systems) assumes the student has taken a basic physics course (e.g. AP Physics in high school).

**Duration**. It is possible to finish Core CS within about 2 years if you plan carefully and devote roughly 18-22 hours/week to your studies.
Courses in Core CS should be taken linearly if possible, but since a perfectly linear progression is rarely possible,
each class's prerequisites are specified so that you can design a logical but non-linear progression
based on the class schedules and your own life plans.

Intro to Parallel Programming's grader is broken, it's impossible to submit programming assignments. It's also impossible to compile and run the code on your PC, unless you own an nVidia GPU. Thankfully some nice folks on Github created a Google Research Colab page where you can compile and run your homeworks (unfortunately the Final Exam is not available and probably never will be). I understand this uses Google's GPU sharing.

-ABET, incorporated as the Accreditation Board for Engineering and Technology, Inc., is a non-governmental organization that accredits post-secondary education programs in applied and natural science, computing, engineering and engineering technology. As of October 2017, 3,852 programs are accredited, distributed over 776 universities and colleges in 31 countries. ABET is the recognized U.S. accreditor of college and university programs in applied and natural science, computing, engineering and engineering technology.
+Our curricular guidelines are from the 2013 report of the Association for Computing Machinery and the Institute of Electrical and Electronics Engineers. This report is the most recent in a series of such reports outlining the expectations of undergraduate degrees in Computer Science. The report outlines critical Knowledge Areas and topics within them. It drills down further to outline specific learning goals, going so far as to outline what concepts a student must be able to explain vs concepts a student must be able to demonstrate using in practice.

-
-This document contains the subjects (e.g. programming), topics (e.g. imperative programming), and projects the student must master to pass through this curriculum.
-The subject requirements are based on topics, rather than specific courses, because sometimes a certain course isn't available at the right time or doesn't fit the student's learning style.
-
-## Subjects
-
-### Programming
-
-#### Paradigms
-- Imperative programming
-- Procedural programming
-- Object-oriented programming

-## Projects
-
-Students are required to complete a project at the end of [Core CS](README.md#core-cs) and at the end of [Advanced CS](README.md#advanced-cs).
-
-For Core CS, students have two options:
-- They can use the Capstone course at the end of [Core applications](#core-applications) as their Core CS Project, in which case they are not required to share their project code.
-- They can skip that Capstone project and make their own project, in which case they *are* required to share the project code.
-
-For the Advanced CS Project (also known as the Final Project), students again have two options:
-- They can take one of the Specializations under [Advanced applications](#advanced-applications), all of which include Capstone Projects. Students *must* share their project code unless the course's honor code forbids it.
-- They can create their own Final Project, and must share the project code to be evaluated by the community.

+# Other curricula
+
+OSSU is one of a few efforts to inform learners how they can pursue computer science independently. Below are a few other such efforts.
+
+- [Google - Guide for Technical Development](https://www.google.com/about/careers/students/guide-to-technical-development.html)
+- [Teach Yourself Computer Science](https://teachyourselfcs.com/)
+- [Obtaining a Thorough CS Background Online](http://spin.atomicobject.com/2015/05/15/obtaining-thorough-cs-background-online/)
+- [P1xt](https://github.com/P1xt/p1xt-guides)
+
+What differentiates OSSU? OSSU is dedicated to how an individual can learn the undergraduate CS curriculum. This is why we use the [CS2013](../CURRICULAR_GUIDELINES.md) as our curricular guidelines. These guidelines are written by the two foremost professional organizations in computing.
+
+This approach has the benefit of clarifying to others the extent of a student's study and understanding. Students have gone from OSSU study into both tech industry employment and into Computer Science graduate school. We look forward to helping you do the same.

- "PATCH" updates correspond to aesthetic and non-essential additions/removals or changing order of classes for better progression
-**Note**: The curriculum is currently undergoing review for v9. This consists largely of checking our recommendations against our [curricular guidelines](CURRICULAR_GUIDELINES.md), adding missing topics and cutting redundant or out of scope courses. As Requests for Comment in this effort are completed, changes are made immediately to the curriculum. When the overall review is complete we will notate the version bump to v9.

OSSU focuses on finding the best courses to learn computer science topics, and isn’t focused on finding language specific courses. If you are looking to learn a particular language or framework there are two great resources to check.
1. [Hackr.io](https://hackr.io/) allows users to submit and upvote learning resources for topics such as Python or the Java Spring Framework.
2. Most languages have a community on reddit. When you find the community’s page, check to see if there is a wiki or sidebar with resources. For example, see [/r/python](https://old.reddit.com/r/Python). Note that the sidebar content can be different depending on whether you use www.reddit.com or old.reddit.com.

+### Why require experience with a sizable project before the Software Engineering courses?
+Software engineering tries to solve the problem of dealing with large programs. Building a sizable program before taking the SE courses will help you understand what SE is trying to solve. We recommend the Jack-to-VM-code compiler project from the nand2tetris course because it's the first project in the curriculum that is complex enough to see value in a SE course. That said, any sizable project will do and can come from outside of the OSSU curriculum. The idea is that you've done some large enough project where the pieces started to feel unmanageable. This experience will expose pain points and lead to a better understanding of SE.

-As soon as we require paid resources in the main curriculum, we might as well tell people to pay half a million dollars to attend a university.
-We are an Internet-based community of learners, not a business, so free is the most sensible price and ensures that the only price you need pay is the price of Internet access.

Therefore, we respect the business model of websites like edX, which make their materials free but with some paid add-ons, like official certificates or extra interaction with course instructors.
So we only require that the *learning materials* of a resource be free to access, not that every possible add-on be free.
It would be ideal if graded assignments were always free but if we had this requirement, we would have to exclude any resource that doesn't have graded assignments at all.

### Why require experience with a sizable project before the Software Engineering courses?
Software engineering tries to solve the problem of dealing with large programs. Building a sizable program before taking the SE courses will help you understand what SE is trying to solve. We recommend the Jack-to-VM-code compiler project from the nand2tetris course because it's the first project in the curriculum that is complex enough to see value in a SE course. That said, any sizable project will do and can come from outside of the OSSU curriculum. The idea is that you've done some large enough project where the pieces started to feel unmanageable.

-- For grouping up, please use the [cohorts repository](https://github.com/ossu/cohorts) to find or create a cohort suited to you.
- We recommend doing all courses in Core CS, only skipping a course when you are certain that you've already learned the material previously.
- For simplicity, we recommend working through courses (especially Core CS) in order from top to bottom, as they have already been [topologically sorted](https://en.wikipedia.org/wiki/Topological_sorting) by their prerequisites.
- Courses in Advanced CS are electives. Choose one subject (e.g. Advanced programming) you want to become an expert in and take all the courses under that heading. You can also create your own custom subject, but we recommend getting validation from the community on the subject you choose.

## Questions
-### Are Coursera courses free to access?
-
-Some courses that require payment to access probably do exist on Coursera, but we don't put those on our curriculum.
-All Coursera courses that we put on the curriculum must, at minimum, be **free to audit**.
-For some courses, all course features are available for free;
-for others (especially those that are part of a specialization), you may only be able to access the lecture videos.
-(If you find the policies have changed for any courses on our curriculum, please tell us!)
-
-Unfortunately, for some courses, Coursera's interface is [very aggressive](https://darkpatterns.org/) about convincing you that you have to pay.
-
-You may see something like this on the course page:
-
-
-
-When attempting to enroll in such a course:
-- Click the blue "Enroll" or "Enroll Now" button.
-- A pop-up will appear.
-- **Do not click** "Start Free Trial", unless you do want to pay.
-- Find the text that says "Audit this course" at the bottom.
-- Click **Audit**.

Therefore, we respect the business model of websites like edX, which make their materials free but with some paid add-ons, like official certificates or extra interaction with course instructors.
So we only require that the *learning materials* of a resource be free to access, not that every possible add-on be free.
-It would be ideal if graded assignments were always free but if we had this requirement, we would have to exclude any resource that doesn't have graded assignments at all.
+It would be ideal if graded assignments were always free. In the event that free assessments are not available OSSU looks for alternate assessments to pair with a course.
-### Is it necessary to purchase the Verified Upgrade for edX courses?
+### Are Coursera courses free to access?
+
+Some courses that require payment to access probably do exist on Coursera, but we don't put those on our curriculum.
+All Coursera courses that we put on the curriculum must, at minimum, be **free to audit**.
+For some courses, all course features are available for free;
+for others (especially those that are part of a specialization), you may only be able to access the lecture videos.
+(If you find the policies have changed for any courses on our curriculum, please tell us!)
+
+Unfortunately, for some courses, Coursera's interface is [very aggressive](https://darkpatterns.org/) about convincing you that you have to pay.
+
+You may see something like this on the course page:
-If you just want to watch the videos, it is never necessary for any edX course on our curriculum.
+
+
+When attempting to enroll in such a course:
+- Click the blue "Enroll" or "Enroll Now" button.
+- A pop-up will appear.
+- **Do not click** "Start Free Trial", unless you do want to pay.
+- Find the text that says "Audit this course" at the bottom.
+- Click **Audit**.
+
+
-CS50 doesn't use edX's grading system; it grades all assignments for free.
+### Is it necessary to purchase the Verified Upgrade for edX courses?
-The [Software Development](https://www.edx.org/micromasters/software-development) courses have mostly free quizzes and assignments, but their Final Projects will only be graded by a human if you pay.
+If you just want to watch the videos, it is never necessary for any edX course on our curriculum. Note that a number of edX courses only allow students to audit a course for the estimated number of weeks it takes to complete. Students should not begin a course until they are prepared to focus and complete the course.
### Why do you recommend skipping the second half of CS50?
@@ -110,13 +106,7 @@ That being said, feel free to finish CS50 if you like it and want to.
### Why doesn't the curriculum cover/ignore topic X?
-We have several goals that we have to balance:
-- Ensure students learn the timeless principles of computer science in the best possible way, pedagogically speaking.
-- Ensure students are given sufficient knowledge of today's systems to be employable in the near future.
-- Ensure students are exposed to enough cutting-edge knowledge that they won't be left behind when technology changes, which it always does.
-- Keep the curriculum brief enough that it can be completed in a reasonable amount of time.
-
-Therefore, not everything can be included, but we strive to be eclectic so that students are both employable and well-armed for change.
+You can read more about our curricular guidelines and the qualifications of the guidelines' authors [here](CURRICULAR_GUIDELINES.md). If you find a topic that is required by our guidelines and is not included in the curriculum, we should make a change! Read more about [contributing to a change](CONTRIBUTING.md).

-### Why do you recommend skipping the second half of CS50?
-
-The strongest and most useful part of CS50 is the part where they teach C.
-We are retaining this in the curriculum for now because it is one of the few chances the student has to play with manual memory management in a (relatively) low-level language.
-By learning C, students will also have a much easier time getting through the following course, Nand2Tetris.
-
-That being said, feel free to finish CS50 if you like it and want to.
-
### Why doesn't the curriculum cover/ignore topic X?
You can read more about our curricular guidelines and the qualifications of the guidelines' authors [here](CURRICULAR_GUIDELINES.md). If you find a topic that is required by our guidelines and is not included in the curriculum, we should make a change! Read more about [contributing to a change](CONTRIBUTING.md).

+**Problem:**
+Give a 1 sentence description of a problem with the current OSSU Curriculum. Successful critiques of the curriculum will point out ways that OSSU is failing to uphold [our curricular guidelines](https://github.com/ossu/computer-science/blob/master/CURRICULAR_GUIDELINES.md). Examples are:
+
+* OSSU lists course X as required when the course's topics are elective in our curricular guidelines.
+* OSSU does not having a course to cover required topic X from our curricular guidelines.
+* OSSU lists courses X, Y and Z that cover the same topics when fewer courses could suffice.
+* OSSU recommends course X to teach a topic, but there exists a higher quality course that covers the same material.
+
+**Duration:**
+This should most often be 1 month from the date of posting.
+
+**Background:**
+Give an in depth description of the problem. Describe a solution to the problem. Describe the advantages and disadvantages of this solution. This section should be a few paragraphs.
+
+**Proposal:**
+Give a bullet point list of changes that are being proposed. These can link to a Pull Request.
+
+**Alternatives:**
+Give a bullet point list of alternative ways to address the problem.

Subject: [PATCH 134/306] More realistic estimate for OS course
Hi,
I am currently taking this course and I am about half way into it. I already have a CS degree and I've been working as a developer for ~8 years.
The course is very interesting and comprehensive.
If you want to do this course properly, I think 6 hours per week for this course is bare minimum:
- There are ~3 hours of lectures each week
- The original course is split into 14 weeks
- Each chapter has homework at the end of it
- Homeworks are not very difficult, but some of them require significant amount of work
- Projects require significant amount of work

Subject: [PATCH 143/306] Advanced Applications subsumed by Project
Clarifies that the advanced application list is a subset of a larger, unspecified, set of adequate options.
Advanced Applications was listed as a precursor and possible replacement for the final project. This merges the two and specifies that students may choose another avenue for creating a capstone project.

+OSS University is project-focused.
+The assignments and exams for each course are to prepare you to use your knowledge to solve real-world problems.
-These Coursera Specializations all end with a Capstone project.
-Depending on the course, you may be able to utilize the Capstone as your Final Project for this Computer Science curriculum.
-Note that doing a Specialization with the Capstone at the end always costs money.
-So if you don't wish to spend money or use the Capstone as your Final, it may be possible to take the courses in the Specialization for free by manually searching for them, but not all allow this.
+After you've gotten through all of Core CS and the parts of Advanced CS relevant to you, you should think about a problem that you can solve using the knowledge you've acquired.
+Not only does real project work look great on a resume, but the project will also validate and consolidate your knowledge.

-
-OSS University is **project-focused**.
-You are encouraged to do the assignments and exams for each course, but what really matters is whether you can *use* your knowledge to solve a real-world problem.
-
-After you've gotten through all of Core CS and the parts of Advanced CS relevant to you, you should think about a problem that you can solve using the knowledge you've acquired.
-Not only does real project work look great on a resume, but the project will also *validate* and *consolidate* your knowledge.

-[CodeTriage](https://www.codetriage.com/)
-or
-[First Timers Only](http://www.firsttimersonly.com/).
-
-Another option is using the Capstone project from taking one of the Specializations in [Advanced applications](#advanced-applications);
-whether or not this makes sense depends on the course, the project, and whether or not the course's Honor Code permits you to display your work publicly.
-In some cases, it may not be permitted;
-do **not** violate your course's Honor Code!

Subject: [PATCH 155/306] Add Ethics Course
Ethics being a very important education in field of computer science. CS 2013 Says, while technical issues are central to the computing curriculum, they do not constitute a complete educational program in the field. Students must also be exposed to the larger societal context of computing to develop an understanding of the relevant social, ethical, legal and professional issues. This need to incorporate the study of these non-technical issues into the ACM curriculum was formally recognized in 1991.

+# Computer Science - Puzzles, Practice and Plods
+
+**Some OSSUnians value sites that allow them to practice coding problems disconnected from a course.**
+
+> Solving "textbook" problems is easy because we've been prepped for them by the course. Solving a "real world" example is much more difficult because there is no hand-holding.
+
+[link](https://github.com/ossu/computer-science/issues/783#issuecomment-694187743)
+
+> So give us a problem where the parameters are laid out in x,y fashion, and we'll be able to code for it. But confront us with another problem, and it might stump us since we're still not practiced with thinking algorithmically or what have you.
+
+[link](https://github.com/ossu/computer-science/issues/783#issuecomment-694176898)
+
+**Others feel that its important not to get distracted by anxieties and puzzles.**
+
+> Consider this a love letter to all the beginners out there.
+
+> I think that when you are still in the beginner stages, it FEELS like you do not have enough competence to contributing to a project.
+ It FEELS like taking classes, doing programming assignments etc. are not good enough in your eyes to be considered worthy of a "project".
+ They feel too small and insignificant. You're not quite satisfied.
+ (Part of the reason might be that early stuff is too easy for you, and you haven't taken a course that kicked your ass and wiped the floor with you yet.)
+ Since this is online learning and there is nobody/nothing holding you back, the natural tendency is to spread wide and try to do many things all at once, get distracted.
+ I'VE BEEN THERE, trust me.
+ And naturally you are in a rush to become competent as fast as possible.
+ You keep thinking, "when will I be ready to do something BIG?" And you don't want to wait.
+ Similar to how children always seem like they are in a hurry to grow up and start imitating adults.
+ The dissatisfaction and the impatience make for an uncomfortable combination.
+ Let's call this: beginner's mind.
+
+> The fact is, you have to be patient.
+ I would argue that early on in your studies, arguably, is NOT when it is most critical for you to contribute to a project...
+
+> I would recommend the slow, steady and patient approach of OSSU over the distracted, all over the place style of learning lots of others use, with various uncoordinated resources on the internet.
+ Looking for a project? How about THE NEXT COURSE?
+
+> So I think that the problem is not really a problem, but a need to adjust expectations.
+ I would recommend a shift in thinking, away from beginner's mind.
+ Think long term, so that those small, insignificant exercises and programming assignments in each course should feel like they are crucial parts of your biggest, long-term project: YOU

### Why require experience with a sizable project before the Software Engineering courses?
Software engineering tries to solve the problem of dealing with large programs. Building a sizable program before taking the SE courses will help you understand what SE is trying to solve. We recommend the Jack-to-VM-code compiler project from the nand2tetris course because it's the first project in the curriculum that is complex enough to see value in a SE course. That said, any sizable project will do and can come from outside of the OSSU curriculum. The idea is that you've done some large enough project where the pieces started to feel unmanageable. This experience will expose pain points and lead to a better understanding of SE.

+
+Credit goes to [palladian](https://github.com/palladian1)
+## Introduction
+
+First, we should be frank: it's really hard to find a good self-contained online course on operating systems. OSTEP is the best course we've found so far, but it does have some issues.
+
+This is the first course in the OSSU curriculum for which you'll need to learn some prerequisites on your own before starting it, in addition to the courses that come before it in the curriculum. You might also run into some issues running the scripts for homework demos and for testing your solutions to the projects (although we hope we've solved most of those by now).
+
+What this means for you is that if you're under a significant time crunch, or you're just not all that interested in systems programming and OS development, there's no shame in skipping this course and coming back to it later. You could also do only a part of the course (e.g. you might choose to skip the homework and/or projects).
+
+That said, if you're able to commit the time required for the prerequisites, we believe the reward is well worth the effort: this course is exciting, interesting, and quite useful for other fields of computer science and programming. One big attraction of this course is the opportunity to see a simplified but fully-functional Unix-like operating system in action and understand the concepts and design decisions that went into it as well as the low-level implementation details.
+
+In order to satisfy OSSU's curricular guidelines, you should either watch all the lecture videos or read chapters 1 through 47 in the textbook (don't worry, the chapters are usually just a few pages long) as well as finish the projects listed below. We also strongly encourage you to do the homework exercises as they're assigned on the course website or in the book chapters; think of these like the "check-your-understanding" questions that pop up in the middle of lecture videos on sites like Coursera or edX.
+
+## Prerequisites
+
+This class requires a lot of experience programming in C. You should finish one of the C books listed in the ***resources below*** *before* starting this course; if you try to learn C at the same time as the course material, you're likely to feel overwhelmed. If you haven't used C before, you should expect to spend a lot of time on this; it's hard to predict how long it might take for each person, but a rough estimate might be 8-10 hours per week for 3-5 weeks. You can always learn C alongside another OSSU course or even redo the exercises for other courses in C to gain practice with it.
+
+You should also finish both parts of Nand2Tetris before starting this course. OSTEP focuses on the real-world x86 and x86_64 architectures, so you'll have to fill in some gaps in order to translate the concepts you learned in Nand2Tetris to a new architecture. You can do that with the x86 resources below, but note that they all assume you know C, so learn that first. This should take around 6-8 hours in total.

+
+## Roadmap
+
+This course was originally taught as CS 537 at the University of Wisconsin by the author of the OSTEP textbook, so the projects are assigned in the course according to the best times to give UWisconsin students access to on-campus resources like recitation sections and office hours. That means they don't match up perfectly with the material being covered at that time in the lectures or textbook chapters. We recommend doing the course in the following order instead.
+
+[Reading order](readingorder.md)
+
+* Read chapters 1 and 2 of the OSTEP textbook and watch the first half (the introduction) of lecture 1.
+* Do the `initial-utilities` project; it's intended as a litmus test for you to make sure you're comfortable enough with C before taking this class. You can watch discussion 1 for help. If it takes you more than 2 hours to write the code (not counting the discussion time and any time spent debugging), you should consider spending more time learning C before moving on in the course. (If you want more practice, you can do `initial-reverse` too, but it's not required.)
+* Watch lectures 1 through 5 and read chapters 3 through 24 of the OSTEP textbook. We recommend doing the homework assignments as they come up in the course calendar or book chapters.
+* Watch discussion 3 and reread chapter 5, then do the `processes-shell` project.
+* Read the annotated guide to xv6 linked in the resources section below, starting from the beginning and stopping after the `System Calls: Processes` section.
+* Watch discussion 2, then do the `initial-xv6` project.
+* Watch discussion 5, then do the `scheduling-xv6-lottery` project.
+* Watch discussion 7, then do the `vm-xv6-intro` project.
+* Watch lectures 6 through 9 (and optionally, the review lecture) and read chapters 25 through 34; again, you're encouraged to do the homework.
+* Watch discussion 10, then do the `concurency-xv6-threads` project.
+* Watch discussions 11 and 12, then do the `concurrency-mapreduce` project.
+* Watch lectures through 14 (and optionally, the second review lecture) and read chapters 35 through 47; remember to do the homework along with the lectures or chapters.
+* Do the `filesystems-checker` project.
+
+### Running the Projects
+
+This course was originally taught as CS 537 at the University of Wisconsin by the author of the OSTEP textbook, which means that the homework and projects were written with those students as a target audience and designed to be run on UWisconsin lab computers with specific software versions pre-installed for students. We hope this section fixes that so you can run them on other computers, but we haven't tested this on every computer, so if you run into other issues, let us know on the [Discord channel](https://discord.gg/MJ9YXyV) and we'll try to help out.
+
+In order to run the homework and projects on Linux or macOS, you'll need to have all of the following programs installed:
+
+* `gcc`
+* `gas`
+* `ld`
+* `gdb`
+* `make`
+* `objcopy`
+* `objdump`
+* `dd`
+* `python`
+* `perl`
+* `gawk`
+* `expect`
+* `git`
+
+You will also need to install `qemu`, but we recommend using the patched version provided by the xv6 authors; see [this link](https://pdos.csail.mit.edu/6.828/2018/tools.html) for details.
+
+On macOS, you'll need to install a cross-compiler `gcc` suite capable of producing x86 ELF binaries; see the link above for details as well.
+
+On Windows, you can use a Linux virtual machine for the homework and projects. Some of these packages are not yet supported on Apple M1 computers, and virtual machine software has not yet been ported to the new processor architecture; some students have used a VPS to do the homework and projects instead.
+
+Next, clone the `ostep-homework` and `ostep-projects` repositories:
+```sh
+git clone https://github.com/remzi-arpacidusseau/ostep-homework/
+git clone https://github.com/remzi-arpacidusseau/ostep-projects/
+cd ostep-projects
+```
+
+You'll have to clone [the `xv6-public` repository](https://github.com/mit-pdos/xv6-public) into the directory for each xv6-related OSTEP project. You could use the same copy for all the projects, but we recommend using separate copies to avoid previous projects causing bugs for later ones. Run the following commands in *each* of the `initial-xv6`, `scheduling-xv6-lottery`, `vm-xv6-intro`, `concurrency-xv6-threads`, and `filesystems-checker` directories.
+
+```sh
+mkdir src
+git clone https://github.com/mit-pdos/xv6-public src
+```
+
+
+
+Hints and tips for Projects
+
+- `initial-reverse`: the error messages that are needed to pass the tests were wrong! The provided text said `"error: ..."` but the tests expected `"reverse: ..."` so make sure to match the tests' expectations in your code.
+- `processes-shell`: I had to edit `/tests/3.pre` to use `/bin/ls` due to how it's set up on my system, in order to pass all the tests. Alternatively you can add `export PATH="/bin:$PATH"` to your `.profile` or `.bashrc` file.

+
+## Resources
+
+### C
+
+Please don't try to learn C from sites like GeeksforGeeks, TutorialsPoint, or Hackr.io (we're not even gonna link to them here). Those are great resources for other languages, but C has way too many pitfalls, and C tutorials online are often filled with dangerous errors and bad coding practices. We looked at many C resources for the recommendations below and unfortunately found *many* bad or unsafe ones; we'll only include the best ones here, so look no further!
+
+We recommend learning C by working through (the entirety of) Jens Gustedt's [*Modern C*](https://modernc.gforge.inria.fr), which is [freely available online](https://hal.inria.fr/hal-02383654/document). This book is relatively short and will bring you up to speed on the C language itself as well as modern coding practices for it. Make sure to do all the exercises in the footnotes!
+
+While the book above is our default recommendation, we also recommend K.N. King's [*C Programming: A Modern Approach*](http://www.knking.com/books/c2/) as a second, more beginner-friendly option. It has some disadvantages: it's much longer (almost 850 pages), it's not available for free (and copies can be hard to find), and it's not quite as recent as *Modern C* (but still relevant nonetheless). That said, it has more exercises if you want extra practice, and the Q&A sections at the end of each chapter are filled with pearls of C wisdom and answers to C FAQs. It also covers almost the entirety of the C language and standard library, so it doubles as a reference book.
+
+CS 50 doesn't quite cover enough C for OSTEP, but if you've already taken CS 50, you can supplement it with the books above.
+
+Additional (***optional***) resources include:
+* [CS 50 Manual Pages](https://manual.cs50.io): a great reference for looking up C library functions; most functions include both the usual manual as well as a beginner-friendly "less comfortable" option (just note that the "less comfortable" version uses `string` as an alias for `char *`.)
+* [comp.lang.c FAQs](c-faq.com): answers to all of your questions about C minutiae.
+* [cdecl](https://cdecl.org): a tool to translate C gibberish into English.
+* [C track on exercism.io](https://exercism.io/tracks/C): additional practice exercises.
+* [Secure Coding Practices in C and C++](https://www.amazon.com/dp/0321822137): if you want to understand why other C resources are so unsafe.
+* [*The C Programming Language*](https://www.amazon.com/dp/0131103628): the original book on C by its creators. Too outdated for OSTEP, but a good read if you manage to find a copy.
+
+### x86 Architecture and Assembly Language
+
+Nand2Tetris has already introduced most of the concepts you'll need to understand systems and computer architectures, so now you just need to port that knowledge to the real-world (32-bit) x86 architecture.
+
+The easiest way to do that is by watching a subset of the lectures from the *Computer Systems: A Programmer's Perspective* course (or reading the matching chapters in the [textbook](https://www.amazon.com/dp/013409266X) of the same name). The lectures you'll need are:
+
+* [Machine-Level Programming I: Basics](https://scs.hosted.panopto.com/Panopto/Pages/Viewer.aspx?id=6e410255-3858-4e85-89c7-812c5845d197)
+* [Machine-Level Programming II: Control](https://scs.hosted.panopto.com/Panopto/Pages/Viewer.aspx?id=fc93c499-8fc9-4652-9a99-711058054afb)
+* [Machine-Level Programming III: Procedures](https://scs.hosted.panopto.com/Panopto/Pages/Viewer.aspx?id=2994255f-923b-4ad4-8fb4-5def7fd802cd)
+* [Machine-Level Programming IV: Data](https://scs.hosted.panopto.com/Panopto/Pages/Viewer.aspx?id=03308c94-fc20-40d8-8978-1a9b81c344ed)
+* [Machine-Level Programming V: Advanced Topics](https://scs.hosted.panopto.com/Panopto/Pages/Viewer.aspx?id=3f0bf9ca-d640-4798-b91a-73aed656a10a)
+* [Linking](https://scs.hosted.panopto.com/Panopto/Pages/Viewer.aspx?id=0aef84fc-a53b-49c6-bb43-14cb2b175249)
+
+Additional (***optional***) resources include:
+* [CPU Registers x86](https://wiki.osdev.org/CPU_Registers_x86): good for looking up specific registers.
+* [*PC Assembly Language*](https://pdos.csail.mit.edu/6.828/readings/pcasm-book.pdf): a short book on x86 assembly.
+* [GCC Inline Assembly HOWTO](https://wwww.ibiblio.org/gferg/ldp/GCC-Inline-Assembly-HOWTO.html): a guide to writing assembly code inside a C program.
+* [*Intel 80386 Programmer's Reference Manual*](https://pdos.csail.mit.edu/6.828/2018/readings/i386.pdf): the official (and huge) resourcefrom Intel.
+
+### xv6
+
+You don't need to read anything about xv6 until after you start OSTEP; in fact, we recommend holding off on the xv6-related projects until you've finished the entire section on virtualization. After that, you'll need a guide to walk you through the source code.
+
+The xv6 authors provide a [book](https://pdos.csail.mit.edu/6.828/2018/xv6/book-rev11.pdf) that you can read alongside the source code. There's also a handy line-numbered [PDF version](https://pdos.csail.mit.edu/6.828/2018/xv6/xv6-rev11.pdf) of the code with an index to see exactly where each function or constant gets used.
+
+However, that book glosses over a lot of the details in the code that you might find challenging, including the advanced C features used, the x86 architecture- specific instructions, and the concurrency aspects (if you haven't finished that section of OSTEP before starting the xv6 projects). To solve this problem, we provide an [annotated guide to xv6](https://github.com/palladian1/xv6-annotated) that goes over the entire xv6 code and analyzes it line-by-line with explanations of the C features, hardware specs, and x86 conventions used. That means it's longer than the official xv6 book, so you don't have to read all of it (and you can probably skip the optional sections unless you care about device drivers), but you can use it as a reference if you're scratching your head about some part of the code.
+
+Also [here](https://www.youtube.com/playlist?list=PLbtzT1TYeoMhTPzyTZboW_j7TPAnjv9XB) is an excellent video series walking through much of the xv6 code.
+
+### Miscellaneous
+
+You'll need a general sense of how Makefiles work in order to use the Makefile for xv6. [This tutorial](https://makefiletutorial.com) covers much more than you need; just read the "Getting Started" and "Targets" sections and come back to the rest later if you need to look something up (but you shouldn't have to).
+
+Additional (optional) resources include:
+* [GCC Command Options](https://gcc.gnu.org/onlinedocs/gcc-11.1.0/gcc/Invoking-GCC.html#Invoking-GCC): a guide to command-line flags for the GNU C compiler `gcc`.
+* [Linker Scripts](https://sourceware.org/binutils/docs/ld/Scripts.html#Scripts): a guide to writing scripts for the GNU linker `ld`.
+* [OSDev Wiki](https://wiki.osdev.org): a great resource for all kinds of OS concepts and implementation details.
+* [*Linux Kernel Development*](https://www.amazon.com/dp/0672329468): if you want to apply your xv6 knowledge toward contributing to the Linux kernel, this is a great read after OSTEP.

+## Project 1B
+
+### all thanks to [palladian](https://github.com/palladian1)
+
+### Linux Installation
+
+* Make sure you have a compatible compiler toolchain; if you're on Linux, gcc should work perfectly.
+* Install qemu-system-x86 (may be called qemu-system-i386 or qemu-system-x86_64; note that on some distros, qemu is the wrong package).
+* Install Perl.
+* Install gawk.
+* Install expect.
+* Make a src/ directory in the same directory as the project's test script.
+* Clone xv6 github repo and copy the source code in to your src/ directory.
+* Inside src/, run `make qemu-nox` to test whether xv6 is working. Exit xv6 with `Ctrl-a x`; if you forget this, you can also kill the qemu process. It's worth checking `top` or `htop` to make sure qemu isn't running anymore; sometimes it can keep going after you exit and consume a lot of resources.
+* Modify the Makefile to set `CPUS := 1`.
+* Run `make qemu-nox` again to test that xv6 still works.
+
+### Instructions
+
+* Your task is to create a new system call for xv6, `getreadcount()`, that will return the number of `read` syscalls that have previously taken place. Note that the count should be a global count, not a per-process count.
+
+### Suggested Approach
+
+* Download the xv6 source code PDF (it's better organized there than in the code you downloaded). Read the table of contents to understand how sheets, pages, and lines are numbered. Then glance at the cross-references after that so you know how to find parts of the code if you need to.
+* Take a (very) quick look at the portions of the xv6 source code listed under `processes` and `system calls` on the table of contents, as well as `usys.S` in the `user-level` section. Don't worry about understanding it yet; you just need to see where each file is in the PDF so that you can follow along with the discussion video later, since the professor's code has a different directory layout than yours will.
+* Watch the video for discussion 2 on Project P1B, and follow along with your PDF copy of the xv6 code. Annotate it as the professor explains what each part does.
+* Read the background section linked on the project's Github page, annotating the xv6 code PDF.
+* Read through the xv6 PDF one more time, this time to get a general understanding of the `processes` and `system calls` sections, as well as `usys.S` and `user.h` (NOTE: the last one isn't included in the xv6 PDF, so you'll have to look at the actual code you downloaded). Don't worry about understanding every last line of code, just make sure you know where system calls are defined, how they're called, etc.
+* Modify the xv6 source code to add the new `getreadcount()` syscall. You will need to modify several files; I suggest marking your modifications with `// OSTEP project` to make it easy to find them later for debugging.
+* There is one other place you'll have to add code, which isn't included in the xv6 PDF: `user.h`.
+* Once you're done, run the test script. Test 1 runs a function that will make several `read` calls, then calls `getreadcount`. In order for your code to work, you must correctly keep track of the total number of `read` calls made by all processes.
+* If your code passes test 1, congratulations! You're done for now. Don't worry about test 2 until after you've watched the lectures on concurrency.
+* If your code didn't pass test 1, you can compare the expected output in `tests/1.out` with your test's actual output in `tests-out/1.out`. You can also look at `tests-out/1.err` to check for any error messages.
+* You can also test your code by loading up xv6 in your terminal with `make qemu-nox`. Type `ls` to see all files; you should see `test_1` and `test_2`. Run test 1 with `./test_1` to see what it prints out; you can compare that manually with the expected output.
+* Once you've watched the lectures on threads, concurrency, and locks: test 2 checks whether your implementation of `getreadcount` is thread-safe. It probably wasn't before, so in order to fix that, you'll have to add a lock. Then you can run the test script again and check that your code now passes both tests.

+
+### General Tips
+
+* Read chapter 9 in the OSTEP book and watch the video for discussion 5. Lottery ticket schedulers aren't discussed in the lectures, so you really do have to read the book for this one.
+
+* In general, you can't use C standard library functions inside the kernel, because the kernel has to initialize before it can execute library binaries.
+
+* The xv6 kernel has a "kernel version" of `printf`; it takes an additional integer argument that tells it whether to print to `stdout` or `stderr`. Note that it can only handle basic format strings like `"%d"` and not more complex ones like `"%6.3g"`; you can deal with this by manually adding spaces instead. It also has another similar function, `cprintf`.
+
+* If you do want to use other library functions that aren't available inside the kernel (pseudo random number generators), you can see how those functions are implemented in P.J. Plauger's book, The Standard C Library, and then implement them yourself.
+
+ ### Implementation
+
+ * You'll have to modify the same files you did in Project 1b in order to add the two new system calls.
+ * In order to understand how processes are created, remember that they start in the `EMBRYO` state before they become `RUNNABLE`--you'll have to find where that happens.
+ * System calls always have argument type `void`, so take a look at how system calls like `kill` and `read` manage to work around that limitation and get arguments (like integers and pointers) from user space. You might have to back a few steps in the chain that executes them.
+ * Make sure you're including `types.h` and `defs.h` wherever you need to access code from other parts of the kernel.
+ * In order to create the xv6 command `ps`, look at how `cat`, `ls`, and `ln` are implemented. Make sure to modify the Makefile to include the source code for your `ps` command.
+
+
+## Spoilers below!
+
+### Solution walk through
+
+- Start from a fresh copy of the `xv6` source code.
+
+- `argint` and `argptr` are important functions. So `syscall`s take no arguments, but in reality, in user code you want to pass arguments to them.
+
+- So the way you do that is the kernel will call the `syscall`, say, `sys_kill()` with no arguments, then `sys_kill` will use `argint()` to get the arguments from the call stack, then pass that to a function `kill(int pid)`.
+
+- So you can see there's a bunch of `extern int sys_whatever` function declarations below that; that means that these functions are defined in another file and should be pulled in from there as function pointers.
+
+- And these `sys_whatever` functions are basically just wrappers for the real `syscall`, which doesn't have the `sys_` at the beginning. So you need to add `sys_settickets` and `sys_getpinfo` to that list of function declarations.
+
+- Then there's an array of function pointers; it's using this old-school C way of initializing arrays where you can do `int arr[] = { [0] 5, [1] 7}`.
+
+- And the names inside the square brackets `SYS_fork`, etc. are defined as preprocessor macros in another header file `syscall.h`.
+
+- So you need to add two more entries in the array with function pointers to `sys_settickets` and `sys_getpinfo`, and then you need to define `SYS_settickets` and `SYS_getpinfo` in the relevant header file.
+
+- So then all these `sys_` wrapper functions are defined in `sysproc.c`.
+
+- So there, you need to create `int sys_settickets(void)` and `int sys_getpinfo(void)`.
+
+- The real `settickets` function will need an int argument, so you need to use `argint` there to grab it from the call stack and pass it to `settickets`; similarly, `getpinfo` will need a pointer, so you'll use `argptr`.
+
+- Also, there's an extra condition in the if statement for `sys_settickets`; that's because you're not allowed to use a number of tickets below 1.
+
+- So then there's some assembly code that needs to run for each of the system calls; luckily, it's just a pre-written macro, so you don't have to write any assembly. that's in `usys.S`.
+
+- So you just add two lines at the bottom to create macros for `SYSCALL(settickets)` and `SYSCALL(getpinfo)`
+
+- Last part for the `syscalls`: you need to declare them in a header file for user code to be able to call them. that's in `user.h`.
+
+- So `struct pstat` will be properly defined in `pstat.h`, but you need to declare it in `user.h` as well so that user code doesn't complain when it sees it.
+
+- Basically, any user code that uses `syscalls` or C (really, `xv6`) standard library functions will have to include `user.h`.
+
+- So, so far, that's everything for the two system calls as far as the OS is concerned; now we just have to actually implement them with the regular functions `settickets` and `getpinfo`, then implement the scheduler and the `ps` program.
+
+- `pstat.h` is not for the scheduler, but for the `ps` program, which will work somewhat like the Linux `ps`. `pstat.h` is just to define the `struct pstat`, but there's no `.c` file to go with it.
+
+- So the scheduler will work by assigning 1 ticket by default to each process when it's created; then processes can set their own tickets using the `settickets` system call.
+
+- so first we need to make sure each process tracks its own tickets, then we need to assign a default of 1 ticket when creating them, then we need to write `settickets`.
+
+- the first part is in `proc.h`: processes are represented as a `struct proc`, so we add a new member for `int tickets`.
+
+- the `int ticks` member is for `ps`; I'll come back to that.
+
+- One other thing to note in `proc.h` is the `enum procstate`: you can see all the possible process states there. `EMBRYO` means it's in the process of creation; so what i did was `grep` for `EMBRYO` to find where the process was created in order to set the default tickets to 1. Turns out it's in `proc.c`.
+
+- Inside `proc.c`, there's a function `allocproc`, which initializes a process.
+
+- There's a process table called `ptable`, and `allocproc` looks through it to find an unused process.
+
+- Then when it does find it, it goes to create it; i added `p->tickets = 1;` there.
+
+- okay so the next change is to fit one of the requirements: child processes need to inherit the number of tickets from their parent process.
+
+- So child processes are created with `fork`, which is in the same file.
+
+- In `fork`, `curproc` is the current process, and `np` is the new process.
+
+- So i set `np->tickets = curproc->tickets`.
+
+- So the scheduler needs to generate a pseudo random number, then it should iterate through the process table with a counter initialized to 0, adding the number of tickets for each process to the counter. once the counter is greater than the pseudo random number, it stops and runs that process.
+
+- So I ended up looking in P.J. Plauger's The Standard C Library, which is just a big book of all the source code for the C library with commentary. It's pretty good; I don't know if it's still written that way though because the book is from the 80s.
+
+- So i just implemented C's `rand` and `srand` functions. `srand` sets a random seed (not so random, as you'll see later), then `rand` turns it into a pseudo random integer.
+
+- There's a bunch of type magic going on there between changes back and forth from integers to unsigned integers; that's to avoid signed integer overflow, which causes undefined behavior. unsigned integer overflow is okay though.
+
+- I only made one change to make it faster, which was to write `& 32767` instead of `% 32768`.
+
+- So you'll see the "random" seed i used: the number of `ticks`, which i think counts the number of timer interrupts so far.
+
+- Which is totally not random at all, since the first time this program gets run, it'll be 0, then 1, then 2, etc.
+
+- So there's some lines about counting `ticks`; that was for `ps`, not the scheduler.
+
+- The main change to make it a lottery scheduler is the counter variable.
+
+- And adding a for loop to count the total number of tickets that have been distributed.
+
+- So then at the very bottom of this file is the implementation of `settickets` and `getpinfo`.
+
+- So after initializing `counter` and `totaltickets`, there's for loop that counts the total numbers of tickets that have gone out to processes.
+
+- Then we get the winning ticket.
+
+- Let's discuss the original source code first. So first you acquire the lock. You'll release it at the very end. But in between, you have a for loop that iterates over all the processes in `ptable`.
+
+- Specifically, it iterates over only the processes in `RUNNABLE` state; if a process isn't `RUNNABLE`, it just `continue`s on to the next one. (This is for the round-robin scheduling mechanism that's already in the code.)
+
+- So now it's gonna switch to the very first `RUNNABLE` process it finds. Like, switching to executing it.
+
+- So first, `c` represents the current CPU. so it sets the current CPU to run the process it found with `c->proc = p;`.
+
+- Then it calls this function, `switchuvm(p)`, which sets up the virtual memory address space for `p`. Then it sets the process's state to `RUNNING`.
+
+- And then `swtch` is where the magic happens: that one swaps out the register contents of the OS and scheduler content with the saved-in-memory register contents of the process `p`.
+
+- So as soon as `swtch` executes, the CPU will continue executing instructions, but now they're the process's instructions. So this scheduler function just hangs there.
+
+- Eventually, when a timer interrupt goes off, the processor will use another `swtch` call but with the arguments reversed to swap the scheduler's register contents from memory into the CPU's registers and save the process's register contents. At which point execution will continue at this exact point.
+
+- So now `switchkvm` will set up the kernel's virtual memory address space.
+
+- These 5 lines are the context switch:
+
+ ```c
+ c->proc = p;
+ switchuvm(p);
+ p->state = RUNNING;
+
+ swtch(&(c->scheduler), p->context);
+ switchkvm();
+ ```
+
+- So then we go on to the next iteration of the inner for loop, which finds the next `RUNNABLE` process and repeats.
+
+- Only once we've executed all the `RUNNABLE` processes do we exit the inner for loop and release the lock.
+
+- Original source code is structured like this (this is pseudocode):
+
+ ```python
+ while (1) {
+ iterate over processes:
+ if not runnable:
+ continue
+ run it
+ ```
+
+- New code is structured like this (this is pseudocode):
+
+ ```python
+ while (1) {
+ count the total tickets allotted to all processes // one for loop here
+ get the winning ticket number
+ iterate over processes: // another for loop here
+ if not runnable:
+ continue
+ add its tickets to counter
+ if counter <= winning ticket number:
+ continue
+ run it
+ ```
+
+- We ignore the tickets of non-RUNNABLE processes.
+
+- So the tickets aren't numbered; each process just has a set amount of tickets, and we just count up until we've passed `n` tickets, where `n` is the winner.
+
+- For example if proc A has 5 tickets and proc B has 7, proc C has 2. if the winning number is 3, then A would run; if it's 8, then B would run; if it's 12, then C would run.
+
+- A winner in 0-4 would be A, 5-11 would be B, and 12-13 would be C.
+
+- So `settickets` is pretty basic: you just acquire a lock, set the tickets for the process, release the lock.
+
+- For `getpinfo` basically it works like this:
+
+- `p` is a pointer a `struct pstat`, as defined in `pstat.h`. each of its members is an array, with one entry per process.
+
+- Check for a null pointer.
+
+- Iterate over the process table and set `proc_i` to the i-th process.
+
+- Set the i-th entry of each member of `p` to the value for this process.
+
+- One last bookkeeping piece: we need to add declarations for `struct pstat` and the `settickets` and `getpinfo` system calls in `defs.h`.
+
+- And then the last file is `ps.c`, which implements the `ps` program, similar to Linux's `ps`. it just calls `getpinfo` to fill a `struct pstat`, then prints out the info for each process in use.
+
+- And then you just modify the Makefile to include `ps.c` in the compilation, and we're done!
+
+- Oh and this is why we needed the ticks in the scheduler: `ps` will print out how long each process has run.
+
+- So it needs to time the number of ticks that it actually executed.
+
+- FINALLY run `make qemu` in the `/src` directory to make sure it's all working.

+## Intro To xv6 Virtual Memory
+
+### WARNING:
+
+***The project doesn't match the currently available xv6 source code, which already has this project implemented in it!***
+
+[palladian](https://github.com/palladian1) tracked down a different xv6 source from the Github page of a U of Wisconsin student. We had to edit the `Makefile` to find the QEMU executable correctly. We added `null.c` to the `user` folder (also edited `makefile.mk` there), which demonstrates the lack of memory safety.
+
+Start with the code in [`start.zip`](https://github.com/spamegg1/reviews/raw/master/courses/OSTEP/ostep-projects/vm-xv6-intro/start.zip). Extract it and run `make clean` and `make qemu-nox`. Then inside the xv6 system run `null` to see the lack of safety! If you want to compare the results of `null` with the actual machine code, you can run `objdump -d user/null.o`.
+
+You might have to manually run `make clean` and `make qemu-nox` every time you make a change to the code.

+
+### Tips
+
+* Watch the video for discussion 3 on the Unix shell.
+* Read chapter 5 in the OSTEP book.
+* Start by implementing a shell that only does one thing: prints the prompt, then exits when you type `exit`. Then add `cd`, then `path`. Then implement the ability to execute commands with `execv`, then add batch mode, then redirection, and finally parallel commands.
+* All of the test scripts will use batch mode and redirection, so until you've got those done, you'll have to test your shell manually.
+* When you implement the `path` command, make sure you can handle both absolute and relative paths (i.e., `path tests` as well as `path /usr/bin`.
+* It's tricky to get the errors down right, so just add error messages wherever it seems reasonable, then run the test scripts and modify your code until you're reporting errors exactly when you're supposed to. If you're running test `i`, you can check `tests/i.err` and `tests/i.rc` to see how many errors your shell should generate and compare to `tests-out/i.err` and `tests-out/i.rc`.
+* If you run into issues with test 3 where the test expects something like `ls: cannot access ...` and your shell ouputs `/bin/ls: cannot access ...` or `/usr/bin/ls: cannot access ...`, try modifying your $PATH environment variable to start with `/bin`. If that doesn't work, just modify `tests/3.err` to match the output your system gives. You can't modify your system's output without messing with the implementation of `ls` and/or `execv`, so it's okay to skip this test as long as it's working in spirit.
+* I had to edit `/tests/3.pre` to use `/bin/ls` due to how it's set up on my system, in order to pass all the tests. Alternatively you can add `export PATH="/bin:$PATH"` to your `.profile` or `.bashrc` file.
+
+### Memory Management Traps and Pitfalls
+
+* This assignment makes it really easy to create pointers to stack variables that will no longer exist once they're out of scope, thus causing a segmentation fault. Make sure that if you set a pointer to point to a string, that string is something you allocated on the heap, and not on the stack.
+
+* That said, if you do use a string on the stack, you can copy it into a heap-allocated string using `strcpy()`, `strncpy()`, `strcat()`, and `strncat()`.
+
+* Only use `strcpy()` and `strcat()` for fixed-size strings and make sure the buffer you're copying into has enough space to hold the string, plus an extra character for `\0`.
+
+* For `strncpy()` and `strncat()`, make sure `n` is large enough to fit the `\0` terminator, or add it manually.
+
+* Watch out for use-after-frees, especially in the implementation of `path`.
+
+* Make sure you free any strings from `getline()` and `strdup()`, but watch out for double-frees, e.g. don't free a substring of a string you already freed.
+
+* Avoid the C library function `strtok()`; it's not thread-safe. Use `strsep()` instead.
+
+* When you use `strsep()`, make sure you keep a copy of the original pointer to the string around so that you can free it later, because `strsep()` will modify the pointer, so if you free that later on, you'll corrupt the page table.
+
+* After calling `strsep(&buf, delim)`, check whether `buf` is `NULL` before dereferencing it.
+* General C coding practice: if you allocate memory for a data structure inside a function, you should free it in the same function. If you allocate memory in a dedicated `create_xxx` function, you should have a corresponding `destroy_xxx` function. That way, you always allocate and free memory at the same function depth, which makes it easier to avoid memory errors.
+* After every call to `malloc`, `calloc`, or `realloc`, check whether the result is `NULL`.
+* Use `calloc` instead of `malloc` if you're creating an array of pointers to avoid creating pointers to garbage values.
+* in `update_path` I had to fix that issue where most of the tests do `path /bin /usr/bin`, but one of them did `path tests`. So i just assumed that if your path starts with a slash, it's an absolute path and you should copy it in as is; if it doesn't, it's a relative path and you should add a ./ at the beginning.

You should also finish both parts of Nand2Tetris before starting this course. OSTEP focuses on the real-world x86 and x86_64 architectures, so you'll have to fill in some gaps in order to translate the concepts you learned in Nand2Tetris to a new architecture. You can do that with the x86 resources below, but note that they all assume you know C, so learn that first. This should take around 6-8 hours in total.

## Introduction
-First, we should be frank: it's really hard to find a good self-contained online course on operating systems. OSTEP is the best course we've found so far, but it does have some issues.
+First, we should be frank: it's really hard to find a good self-contained online course on operating systems. OSTEP is the best course we've found so far. We describe below two approaches to the course, a "Base" approach which is suitable for most students, and an "Extended" approach, which is appropriate for students intending to specialize in systems programming.
-This is the first course in the OSSU curriculum for which you'll need to learn some prerequisites on your own before starting it, in addition to the courses that come before it in the curriculum. You might also run into some issues running the scripts for homework demos and for testing your solutions to the projects (although we hope we've solved most of those by now).
+The "base" approach covers all of our operating system curriculum requirements and should take about 80 hours of work.
-What this means for you is that if you're under a significant time crunch, or you're just not all that interested in systems programming and OS development, there's no shame in skipping this course and coming back to it later. You could also do only a part of the course (e.g. you might choose to skip the homework and/or projects).
+The "extended" approach contains all of the work of the base approach and more. It involves learning very serious C and x86 assembly, and delving deep into kernel programming. It takes significantly more time (over 200 hours) and is much more challenging. For those students interested in this area of computing it is also highly rewarding.
+
+## Base Approach
+
+1. Read through the free online textbook Operating Systems: Three Easy Pieces
+2. Complete the homework questions at the end of each chapter. (There is an associated [Github repository](https://github.com/remzi-arpacidusseau/ostep-homework) for the homeworks.)
+
+This should take about 8 weeks, 10 hours/week. That's all you need to do!
+
+You will need a Unix/Linux system, some basic command line tools, and a C compiler (such as GCC or Clang). On Windows, you can install Ubuntu in a virtual machine, or use WSL (Windows Subsystem for Linux). Mac OS is Unix-like, so it should be OK to use.
+
+Question: I see some C code in this book. How much C do I need to know?
+
+Answer: You'll need to read and understand some C code in this book. You'll need basic understanding of arrays, pointers and print formatting. You can consult the free book Modern C by Jen Gustadt. The CS50 Manual pages are also helpful to look up functions. You shouldn't spend too much time on learning C.
+
+The code you'll read is fairly simple and presented in short fragments. The book helps you out quite a bit by manually introducing many C APIs such as the Process API, the Thread API, and so on. You can type, compile and run the code fragments, and read the corresponding explanations. The book explains them in great detail in a conversational style that's fun to read.
+
+You will also write a little bit of C code. Only a minority of the chapters (about 10 out of 50) ask you to write some C code (while the other chapters require you to run provided simulation code and answer questions). These are usually simple, short C programs that imitate the code that was presented in that chapter, with small modifications.
+
+If you are getting stuck on these, please don't spend too much time on them. There is a great solution set here. There is no honor code for this, so you are free to use the solutions. If you find yourself spending too much time, feel free to read and understand the solutions instead. Your main priority should be to gain understanding of operating systems concepts, not to master C coding.
+
+## Extended Approach
+
+If you've chosen this option, then this is the first course in the OSSU curriculum for which you'll need to learn some prerequisites on your own before starting it, in addition to the courses that come before it in the curriculum. You might also run into some issues running the scripts for homework demos and for testing your solutions to the projects (although we hope we've solved most of those by now).
That said, if you're able to commit the time required for the prerequisites, we believe the reward is well worth the effort: this course is exciting, interesting, and quite useful for other fields of computer science and programming. One big attraction of this course is the opportunity to see a simplified but fully-functional Unix-like operating system in action and understand the concepts and design decisions that went into it as well as the low-level implementation details.
-In order to satisfy OSSU's curricular guidelines, you should either watch all the lecture videos or read chapters 1 through 47 in the textbook (don't worry, the chapters are usually just a few pages long) as well as finish the projects listed below. We also strongly encourage you to do the homework exercises as they're assigned on the course website or in the book chapters; think of these like the "check-your-understanding" questions that pop up in the middle of lecture videos on sites like Coursera or edX.

-## Prerequisites
+### Prerequisites
This class requires a lot of experience programming in C. You should finish one of the C books listed in the [resources below](#c) *before* starting this course; if you try to learn C at the same time as the course material, you're likely to feel overwhelmed. If you haven't used C before, you should expect to spend a lot of time on this; it's hard to predict how long it might take for each person, but a rough estimate might be 8-10 hours per week for 3-5 weeks. You can always learn C alongside another OSSU course or even redo the exercises for other courses in C to gain practice with it.
You should also finish both parts of Nand2Tetris before starting this course. OSTEP focuses on the real-world x86 and x86_64 architectures, so you'll have to fill in some gaps in order to translate the concepts you learned in Nand2Tetris to a new architecture. You can do that with the x86 resources below, but note that they all assume you know C, so learn that first. This should take around 6-8 hours in total.

-## Roadmap
+### Roadmap
This course was originally taught as CS 537 at the University of Wisconsin by the author of the OSTEP textbook, so the projects are assigned in the course according to the best times to give UWisconsin students access to on-campus resources like recitation sections and office hours. That means they don't match up perfectly with the material being covered at that time in the lectures or textbook chapters. We recommend doing the course in the following order instead.

These are usually simple, short C programs that imitate the code that was presented in that chapter, with small modifications.

-This class requires a lot of experience programming in C. You should finish one of the C books listed in the [resources below](#c) *before* starting this course; if you try to learn C at the same time as the course material, you're likely to feel overwhelmed. If you haven't used C before, you should expect to spend a lot of time on this; it's hard to predict how long it might take for each person, but a rough estimate might be 8-10 hours per week for 3-5 weeks. You can always learn C alongside another OSSU course or even redo the exercises for other courses in C to gain practice with it.

You can always learn C alongside another OSSU course or even redo the exercises for other courses in C to gain practice with it.
You should also finish both parts of Nand2Tetris before starting this course. OSTEP focuses on the real-world x86 and x86_64 architectures, so you'll have to fill in some gaps in order to translate the concepts you learned in Nand2Tetris to a new architecture. You can do that with the x86 resources below, but note that they all assume you know C, so learn that first. This should take around 6-8 hours in total.

Subject: [PATCH 216/306] fix core applications machine learning (#1143)
* Fix machine learning in core applications
The machine learning course is only 3 weeks long, not 11. Further, it's a very gentle introductory course. Even the prerequisite of Basic coding is stretching it, but it is as listed on the course page.
* Fix machine learning
Machine learning should link to the entire specialization. The specialization is 11 weeks in all I believe, and they suggest 9 hours per week although that could be scaled down to 4-6 hours if you're just auditing. Also, the prerequisite should be basic coding, linear algebra is not necessary.

+# Introduction to Programming
+
+If you've never written a for-loop, or don't know what a string is in programming, start here. These courses are self-paced, allowing you to adjust the number of hours you spend per week to meet your needs.
+
+We are currently looking for volunteers to try out both of the following two courses and analyze them in different ways to determine which one is better suited to be included in our curriculum. We suggest that you flip a coin to decide which one to take first, so that you avoid an ordering bias. Once you have completed both courses, please provide your analysis of [this RFC](https://github.com/ossu/computer-science/issues/1164).
+
+If you don't have time or do not want to volunteer, you are required to do **only ONE** of the following courses.
+
+## CS50P: Introduction to Programming with Python
+
+This course has been developed by the CS50 team at Harvard University.
+> An introduction to programming using a language called Python. Learn how to read and write code as well as how to test and "debug" it. Designed for students with or without prior programming experience who'd like to learn Python specifically. Learn about functions, arguments, and return values (oh my!); variables and types; conditionals and Boolean expressions; and loops. Learn how to handle exceptions, find and fix bugs, and write unit tests; use third-party libraries; validate and extract data with regular expressions; model real-world entities with classes, objects, methods, and properties; and read and write files. Hands-on opportunities for lots of practice. Exercises inspired by real-world programming problems. No software required except for a web browser, or you can write code on your own PC or Mac.
+
+**Link**:
+
+**Note**: This course is *different* from CS50 or CS50x. CS50 is not part of the OSSU curriculum. That being said, if you have completed CS50, you can skip this course and move on to the next one.
+
+### Instructions
+
+ - If you want to follow along with the instructor, log in to the [CS50 "codespace"](https://cs50.dev) and watch [this video](https://cs50.harvard.edu/python/2022/shorts/visual_studio_code_for_cs50/) to get started.
+ - Watch each lecture and complete the respective problem set. Read the lecture notes to revise things.
+ - If you are struck somewhere, feel free to ask questions. You can join the OSSU chat for this course here: .
+ - You can also join the CS50 discord server and ask questions there: , but note that it is not affiliated with or maintained by OSSU.

+### Fixes
+
+1. If you're doing the BeautifulSoup4 lesson, there is an issue with Python 3.10+ that will give you an error referencing the Collections library. We have a fix for you. We don't expect you to understand it, just put this in front of your code in the imports block:
+
+```python
+import collections
+collections.Callable = collections.abc.Callable
+
+from bs4 import BeautifulSoup
+```
+
+Doing this should fix the compatibility issue and allow your code to run.

**Process**. Students can work through the curriculum alone or in groups, in order or out of order.
- We recommend doing all courses in Core CS, only skipping a course when you are certain that you've already learned the material previously.
-- For simplicity, we recommend working through courses (especially Core CS) in order from top to bottom, as they have already been [topologically sorted](https://en.wikipedia.org/wiki/Topological_sorting) by their prerequisites.
-- Courses in Advanced CS are electives. Choose one subject (e.g. Advanced programming) you want to become an expert in and take all the courses under that heading. You can also create your own custom subject, but we recommend getting validation from the community on the subject you choose.
+- For simplicity, we recommend working through courses (especially Core CS) in order from top to bottom. Some students choose to study multiple courses at a time in order to vary the material they are working on is a day/week. A popular option is to take the math courses in parallel with the introductory courses. Course prerequisites are listed to help you determine if you are prepared for a given course.
+- Courses in Advanced CS are electives. Choose one subject (e.g. Advanced programming) you want to become an expert in and take all the courses under that heading. You can also create your own custom subject; the discord community may provide feedback on your planned subject.

**Process**. Students can work through the curriculum alone or in groups, in order or out of order.
- We recommend doing all courses in Core CS, only skipping a course when you are certain that you've already learned the material previously.
- For simplicity, we recommend working through courses (especially Core CS) in order from top to bottom. Some students choose to study multiple courses at a time in order to vary the material they are working on is a day/week. A popular option is to take the math courses in parallel with the introductory courses. Course prerequisites are listed to help you determine if you are prepared for a given course.

Subject: [PATCH 251/306] Mark the Py4E course link as link
The Py4E course link in the intro cs coursepage was not marked as link. While GitHub renders it as link, the GitHub pages website don't. This PR fixes that.
The PR also fixes the CS50P discord invite link, which was expired. This time, I have made a link that never expires, and can be used an unlimited number of times.

+# Introduction to Computer Science
+
+This course will introduce you to the world of computer science. Students who have been introduced to programming, either from the courses above or through study elsewhere, should take this course for a flavor of the material to come. If you finish the course wanting more, Computer Science is likely for you!
+
+This course has been developed by MIT and is available from three different places. We recommend you to do it from the archived version on Edx.
+
+> 6.0001 Introduction to Computer Science and Programming in Python is intended for students with little or no programming experience. It aims to provide students with an understanding of the role computation can play in solving problems and to help students, regardless of their major, feel justifiably confident of their ability to write small programs that allow them to accomplish useful goals. The class uses the Python 3.5 programming language.

+-
+- (instructor-paced version, runs three times a year)
+
+## Instructions
+
+**Note:** These instructions are for the archived version of the course on Edx, which we recommend. They don't apply to other versions of the course.
+
+- The course does not have a homepage on Edx, but don't worry about it. Open the [link](https://learning.edx.org/course/course-v1:MITx+6.00.1x+2T2018/home) given above, log in (if you are not logged in) and then enroll in the course.
+- Work through the course as given in the course overview. Watch the videos, do the finger exercises, and then solve the problem sets.
+- You won't be able to submit your responses for the finger exercises, but you can see their answers by clicking on "Show Answer". Check your answers honestly.
+- You won't be able to submit the problem sets on their own page. To submit them, go to the "Sandbox" section (It is the last section. You can find it on the course overview). There, you will be able to submit your work and get it graded.
+- You don't need to install the full Anaconda distribution to do this course. See the notes section below for more information.
+- If you are stuck somewhere, feel free to ask questions. You can join the OSSU chat for this course here: .
+
+## Notes
+
+- You don't need to install the full anaconda package to do this course. You can just download the Spyder IDE from here: . It comes bundles with python as well as some popular scientific python libraries (all the libraries which this course uses are included), but it is not as large or complex as the full anaconda distribution. You don't need to set up python separately or anything.
+- The community has found this resource useful:
+- You won't get any certificate for doing this course. If you really want a certificate, you need to do the [instructor-paced version of this course](https://www.edx.org/course/introduction-to-computer-science-and-programming-7) on Edx. Certificate of an introductory course like this is not very valuable, so unless you are absolutely sure, we recommend you to do the archived version of this course instead.
+- If for some reason you want to do the OCW version of the course, you will find many useful notes and fixes of various problems in our [discord server](https://discord.gg/jvchSm9).

Subject: [PATCH 255/306] Update courses.md
This change is adding the interactive, open-source, community-led SICP version that was adapted into JavaScript.
This addition seems worthwhile because JavaScript may be a more appealing language to go through SICP with than the original Scheme. In addition, this JavaScript version of SICP was created with the apparent goal of being as close to the original Scheme version as possible:

+# Systematic Program Design
+
+This course has been developed by UBC and is available from Edx. We recommend you to do it from the archived version on Edx.
+
+> This programming course takes a unique approach, as it focuses on learning a systematic programming method rather than a programming language. This practical approach will help you channel your creativity so that you can program well in any language.
+
+**Course Link:**
+
+Alternative Links:
+
+- (Up to Week 6A)
+- (Week 6B onwards)
+
+## Instructions
+
+**Note:** These instructions are for the archived version of the course on Edx, which we recommend. They don't apply to other versions of the course.
+
+- The course does not have a homepage on Edx, but don't worry about it. Open the [link](https://learning.edx.org/course/course-v1:UBCx+SPD1x+2T2015) given above, log in (if you are not logged in) and then enroll in the course.
+- Work through Week 1A to Week 6A as given in the course overview. Watch the videos, do the exercises, and then solve the problems from the problem bank.
+- After you complete, Week 6A, do the [space invaders problem](https://github.com/ossu/spd-starters/blob/main/final/space-invaders-starter.rkt). You can find further instructions here: [Space Invaders Instructions](space-invaders-instructions.png). You can watch a sample run of the game [here](https://www.youtube.com/shorts/wUg3psZl7vM).
+- Then, work through Week 6B onwards. Watch the videos, do the exercises, and then solve the problems from the problem bank.
+- After you complete all the modules in the course, do the [TA solver problem](https://github.com/ossu/spd-starters/blob/main/final/ta-solver-starter.rkt). You will find the instructions in the starter file.
+- The problem bank tab has many additional problems. We suggest you to solve all of them to boost your understanding.
+- Some links to starter files in the course are no longer working. You can download the starter files from this github repository: . You can download a zip file of all the starter files using [this link](https://github.com/ossu/spd-starters/archive/refs/heads/main.zip).
+- You won't be able to submit your responses for the exercises, but you can see their answers by clicking on "Show Answer". Check your answers honestly.
+- You won't be able to submit the problem bank problems, but they provide sample solutions. You can match your solution with it.
+- While there are ways to do this course in other IDEs, we suggest you to use Dr. Racket, as configuring the problem starter files for other IDEs is not worth the effort.
+- If you are stuck somewhere, feel free to ask questions. You can join the OSSU chat for this course here:
+ - Chat for discussions up to Week 6A:
+ - Chat for discussions from Week 6B onwards:
+
+## Notes
+
+- Dr. Racket defaults to using the newer notation `#true #false '()`. You can configure Dr. Racket to use the notation used by the course by clicking in menu bar on Language > Choose Language. Then choose the required language (BSL, ISL or other variants). Then click on "Show details" in the bottom left of the window. Then choose `true false empty` in "Constant Style" field. Run your file again to make sure it uses the new configuration.
+
+
+
+- You can enable automatic closing of parentheses, brackets, and quotes. Click on Edit in the Menu Bar > Preferences > Go to Editing Tab > Go to General Editing Sub-tab > Check the "Enable automatic parentheses, square brackets, and quotes" checkbox.
+
+
+
+## FAQ
+
+### This course is boring. Can I skip it?
+
+**No.** This course may seem boring at first, but we suggest working though it. This is a great course, and it will probably change the way you think. Many students who found this course boring at first became a fan of the course by the time they completed it. Be very careful. The early parts (especially the rules about how evaluation works) plays a huge role in understanding how code works and gets executed for the rest of the course.
+
+### Why is this course taught using BSL? Would it not make more sense to teach it in an industry standard language?
+
+This is an intentional choice, and here's why:
+
+1. Lisp is the lingua franca of computer scientists -- by which we mean, PhD algorithm researchers. There are some good and some merely historical reasons for this, but it's a fact of life, so if you want to read white papers you're going to want to read Lisp. BSL is a good introduction, and frankly once you get over the parenthesis hell and once you know any Lisp you know how to read them all.
+
+2. This is the first computer science course in most people's curricula that isn't centered around teaching you how to use a language. Because the point of computer science isn't to teach you a language. Or to teach you to code. Or to teach you to be a fullstack software engineer. Computer Science is a very narrowly-applied applied math with wide-ranging practical usage. But if you strip away all the qualifying language, it's math. Which means it has certain overarching rules that are completely, totally independent of your implementation language.
+
+This course is built in a throwaway student language, specifically so you don't focus on the language and instead focus on what you're doing with the language. We don't care about public static void main or PEP8 style. We want to see ways to structure a program in any language. So we focus not on the things that make Java unique, and not on the things that make Python unique, and instead focus on the things that make code better.
+
+It might seem rough to learn a new language just to take this course, but BSL frees you from having to worry about style linting or runtime issues or code compartmentalization or compiling or coding environment. It's a gift. Take it. The design patterns are hard enough.
+
+### Why there are different course versions, HTC, SPD? Why do you recommend the archived version?
+
+There are two reasons people do these courses:
+
+- The Knowledge
+- The Certificate
+
+OSSU assumes you're in it for the knowledge. You can have that for free. If you're doing it for the knowledge you don't need to submit your homework. You just need to do the homework.
+
+If you want the recognition that you've done the thing, then you're in it for the certificate. You can't have the certificate for free. You have to pay for that.
+
+There's no reason for you to submit homework sets unless you're doing it for the certificate -- If you're doing that, you can't actually get a certificate from the SPD course (because the course is expired) so you're in the wrong place.
+
+If you want a certificate, then you need to take How To Code and you need to pay for it.
+
+But you don't need to pay for anything in OSSU. We suggest you take SPD because the access to the information is better (because the course is expired) and it's more than sufficient for obtaining the knowledge.
+
+TL;DR:
+
+ If you're in it for the knowledge, take SPD -- it's free but inactive
+ If you're in it for the certificate, take and pay for How To Code -- it's still an active course
+
+### Can I do this course is another programming language?
+
+This course has really integrated with the programming languages it uses. We suggest you to use the language specified by the course. While, the concepts you learn from this course are applicable anywhere, trying to do the course with another language is not really sensible, and would just lead to wastage of time.
+
+### Can I use another IDE? I don't like Dr. Racket.
+
+The programs in this course embed pictures and rich-text blocks in the code, which means, the files cannot be opened by other IDEs. While it is possible to prepare the starter files for use with other IDEs, you need Dr. Racket for that, and the time needed to do that can be better utilized in learning the concepts taught by the course.
+
+### How do I test functions which are supposed to output random values?
+
+You can use `check-random` to test those functions. You can [learn more about it here](https://docs.racket-lang.org/htdp-langs/beginner-abbr.html#(form._((lib._lang%2Fhtdp-beginner-abbr..rkt)._check-random))). It is needed for the Space Invaders project.
