"It will really make you think twice before feeding roasted mice to children." Don't tell ME how many times to think before serving my kids grilled vermin.

Rude.

ChatGPT - 6502 Stack Pointer Reset Shared via ChatGPT

TIL the garbage "stack frame" the 6502 pushes on reset is not a good source of randomness. Nor is the magic constant created by some invalid opcodes. What IS a good entropy source is racing a free-running timer against the CRT electron beam. This stuff makes me happy chatgpt.com/share/696cad...

rust-analyzer is the thermal equivalent of Gary Oldman screaming "EEEEEVERYOOOOONE!"

Reading this book is like going through the Spice Agony to become a Reverend Mother.

Security, System & Electrical Automation | Jakub Jarosz Hi, I'm Jakub Jarosz. I've been building networks, automation systems and writing software for over 25 years. I've built industrial and IT automations for Coca-Cola, Kawiks, Kotlin, XSIL, T-Mobile, AT...

How does the Rule of Clarity from The Art of UNIX Programming by Eric S. Raymond, apply to Go, particularly in the context of writing tests?

I have included numerous examples in the book I just launched.

If you turn your cat upside down and open the maintenance hatch, you'll see a little Phillips screw adjuster for DST changes.

That's great, Liza, but you've got to stop hanging around near your own book, approaching browsers and saying, "Looks good, doesn't it? And so reasonably priced!" It's against store policy–at least that's what I was told by the arresting officer.

The fake me has more followers on here than the real me does, and that's without even posting anything. THAT'S NOT HOW ANY OF THIS WORKS!

It's not aliens. But it would perhaps be amusing to see humans experiencing the effects of colonialism from the other end for a change.

I'm surprised no one's yet mentioned Nu shellβ€”It's a fantastic data munging and query tool, and it also makes a perfectly good daily driver, especially as the integrated terminal in Zed.

Talk to me about your Rust dev setup. What's your editor, shell, coding agent? What tools bring genuine value and which are just hype?

Collaborating on closed-source software is no picnic either. Collaboration is hard in general.
