RIP Niklaus . Wirth's was among the first programming languages I actually enjoyed, after love-hate with , and . I did loads of programming in Pascal in the 1970s and 1980s, on , and on the first IBM PCs (). Then, . If you are using a device today (I am!), that's another outcome of Wirth's vast ouvre!

what git jargon do you find confusing? thinking of writing a blog post that explains some of git's weirder terminology: "detached HEAD state”, "fast-forward", "index/staging area/staged", “ahead of 'origin/main' by 1 commit”, etc

(really only looking for terms that you personally find confusing, not terms that you think someone else might be confused about)

what helps people get comfortable on the command line? https://jvns.ca/blog/2023/08/08/what-helps-people-get-comfortable-on-the-command-line-/

Would love more stories of things that helped you in the last ~5 years!

(as usual, no need to reply if you don’t remember, or if you’ve been using the command line comfortably for 15 years — this question isn’t for you :) )

@b0rk Place 'alias rm="rm -i"' i .bash_aliases so 'rm' prompts for confirmation. Can explicitly override with -f.

behind "hello world" on Linux https://jvns.ca/blog/2023/08/03/behind--hello-world/

@b0rk Thanks for this post. I would really love to see a complementary post: 'Behind "write()" on Linux': system calls, despatch to device, device drivers, UARTs and terminal windows, ...

Of course, 'write()' is a huge topic, but just restrict it to 'write (1, "Hello World", 12)'

Thanks!
PS: thanks for all the wonderful blogs and zines!

@b0rk There is a vast (too vast!) selection of Linux books out there, but this proposed blog post would have to pick a delicate path through just what's needed to explain 'write (1, "Hello World!")' (and I know I'm not expert enough to do that!).
