At first, the purple links had me convinced that I'd already clicked on them.
Hendrikto 2026-02-24 11:37 UTC link
Great to see a chapter on version control. It is such a shame that almost no CS program teaches proper version control. VCSs and the commit history can be such a tremendously valuable tool when used correctly.

git bisect/blame/revert/rebase/… become so much less useful when VC is treated as a chore and afterthought, and basically amounts to: “Feature is done, my work is complete, just do `git commit -am "changes"` and be done with it.”. And don’t get me started on commit messages.

It is shameful that for a large part of the industry, this is the norm. It is shameful that for a lot of professional, who call themselves software architects or reliability engineers and such fancy titles, still have essentially no idea what they are doing with git, and their response when git add/commit/push/pull don’t work is to shrug, and just delete and re-clone the repo.

Version control should be treated with care and attention to detail. It pays for itself 100 times over.

If your commit history is maintained and tells a story, it is a joy to review your PR. If you just `git commit -am "try fix"` 26 times over, and all that is left in the end is a ball of mud, it is horrible.

> In particular, we’re curious to hear the community’s take on our inclusion of AI-related topics

I think this is fine and if anything you should give it more space. It doesn't replace foundational understanding, but the course is explicitly about "practical" aspects, we can assume said foundational understanding is developed in other courses.

Something like "build your own agent" would be a great intuition pump. The model is doing the heavy lifting and a basic harness is a couple hundred lines of simple code. It could fit in a single lecture and it would be very high signal in my opinion.

ILoveHorses 2026-02-24 11:50 UTC link
Not an entire semester, but I'm really glad my uni had a semester long core CS course on exactly this. Still one of the most useful courses I've ever taken, I refer my notes from that class even now.
lordnacho 2026-02-24 12:07 UTC link
In some way this could be the most important course.

You don't appreciate it when you're studying, because obviously it sounds a bit soft. But when you're learning how something works, often the thing that stops you isn't the fundamentals, which you know what are, it's the little frustrations like not knowing how to commit or pull code, or not knowing how to navigate the terminal.

pards 2026-02-24 12:11 UTC link
One of my large enterprise clients currently requires all tech staff to complete 18h (yes, eighteen hours!) of "agile training", in addition to speed-running 14 separate mandatory online courses.

This time would be much better spent watching these 9h of lectures.

andersmurphy 2026-02-24 12:30 UTC link
Is this going to be like when Sun paid universities to use/teach Java? Just with Anthropic and LLMs?
projektfu 2026-02-24 13:14 UTC link
I'd include sed and awk, because these tools are ubiquitous and can accomplish in a few readable lines what people write long programs to handle in other languages, seemingly because they are unaware of sed and awk, don't know how to use them, or are required for some reason to do it in the project language.

In fact, generally teaching people to select the right tool for the job is a good skill to prevent them from using golden hammers.

NoNameHaveI 2026-02-24 13:46 UTC link
I'm glad to see there is a "Beyond the Code" section that discusses comments. Here's what I typically told my students in Intro to Programming" Good comments lend insight into the code. Reading the code itself tells you the what. Comments should explain the why. Comments like "i+=1; /* Increment i */" are of little value. However comments such as "We increment i mid loop so that we can peek ahead at the next value for a possible swap" are more useful. Use a narrative voice when writing comments, like you are explaining the code to your grandparent. This make digestion easier. Remember, code spends most of its life, and most of its expense, in the maintenance phase. The easier you make your code to understand, the less it will cost and the longer it will live.

Personal hygiene is worth a mention.
Arun2009 2026-02-24 15:04 UTC link
Just wondering - do you include information on interviewing, salary negotiation, communication with management, leading teams, and maybe topics on career progression?

These would have been very useful to me back when I was in the university.

a-dub 2026-02-24 15:09 UTC link
maybe would be interesting to include a lecture on how to interact with the open source community and successfully contribute to an open source project while respecting maintainer time and energy (and other unwritten rules of (n)etiquette).

edit: already in the "beyond the code" section... cool!

If you want to master the shell (it will save years of your life), follow these guides. I highly recommend reading the entire BASH manual, it will answer every question you'll ever have, or at least give you a hint about it, as well as expose you to all the hidden knowledge (some call it "gotchas") you'll wish you knew later.

  101
  - Bash for Beginners (https://tldp.org/LDP/Bash-Beginners-Guide/html/)
  - Bash Tutorial (https://www.w3schools.com/bash/)

  201
  - Bash Programming (https://tldp.org/HOWTO/Bash-Prog-Intro-HOWTO.html)
  - Advanced Bash Scripting Guide (https://tldp.org/LDP/abs/html/)

  301
  - The Bash Manual (https://www.gnu.org/software/bash/manual/bash.html) (https://man7.org/linux/man-pages/man1/bash.1.html)
  - ShellCheck (https://www.shellcheck.net/)
To find every Unix-y program and get a 1-line description of it (and referenced programs/functions), run:

  for i in $(ls /bin/* /usr/bin/* /sbin/* /usr/sbin/* | sed -E 's?.*/??g' | sort -u) ; do
    echo "command: $i"
    whatis "$(basename "$i")" | cat
    echo ""
  done | tee command-descriptions.log
View 'command-descriptions.log' with less command-descriptions.log, use arrow-keys and page up/down to navigate, and type 'q' to exit. To find out more about a program like df(1), run man 1 df.

How about including a course in touch-typing that emphasizes the computer keyboard rather than the typewrite keyboard?
caillou 2026-02-24 17:05 UTC link
In terms of shell, I moved to the fish shell 5 years ago.

Things are so much easier. No need to a massive amount of plugins and configs, mostly works out of the box.

ghc 2026-02-24 17:20 UTC link
That's actually brilliant! Most of my classes only taught what tools were needed to accomplish coursework, not generally useful tools. Even our OS class focused on the workings of the kernel, not the Unix philosophy and how it influenced what tools were included, and how to use them. Then again, 20 years ago the year of the linux desktop was much farther away than it is today...

When I was a Physics Ph.D. student in NYU in the late nineties, I took a course called UNIX tools in the CS department. It was a hands on course where the instructor did live REPL in the terminal and we watched him showing us all the tricks. I got hooked with UNIX since then. Got myself a dialup terminal in my tiny apartment in east village and dial in to the workstation on campus. The latency is so bad that I can’t only see the feedback after a few keystrokes. That was when I trained my vi muscle memory. (EMacs was out of the question.)

Later I got my own IBM 386 and installed Linux on it and started to program in Perl …

I am a big fan of Jon’s YouTube videos on Rust and I started to use Rust in non conventional ways.

I am going to follow this lecture series and “port” them to rustdoc and see how it goes.

Another rabbit hole to fall down, it is going to be fun.

Huge blindspot, especially with all the AI coding going on now... Testing

Purdue CompE has long had a 1 credit hour course that is just this. Lots of bash and git and then a little Python and Tkinter at the end. Other courses them assumed we had this knowledge - the 300-level ASIC class had us submit assignments by pushing to a remote, for instance. Definitely one of the most useful credit hours I had.
