I think if you tell those people directly how it makes YOU FEEL (not accusing them) ie the lack of reaching out makes me feel X, people usually are receptive and try to make an effort

Its fairly common IMO (i feel the same way) A lot of people just have shit going on and don't realize they havent reach out.

“Please come back to the group chat. We are making thanksgiving plans and we need your input.”

“As I said in the group chat, you shouldn't be using iMessagw. Signal is better Opsec. Once everyone starts taking that seriously you know where to find me.”

“Gam Gam is 92. She barely knows how to use the phone she has.”

Type-safe, type-unsafe, single-thread, multi-thread, getting Rust and C++ to work together on this project was like using crabs as gears. Michael Gibson and Shuxian Wang brought down the house at #RustUnconf this year with this story, and here it is on our blog. Link below.

#rustlang hot take: We should rename .unwrap() to .or_panic(). (And .expect() to .or_panic_with().) "Unwrap" is a terrible name for the panicking function, especially since we also have things like .unwrap_or() and .unwrap_or_default() which never panic.

How do you test software, if you want to be *really* thorough about it? To answer that question this week we're going as far back as the 8-Bit Nintendo, as far down as the CPU, and nearly as far up and away as Mars. Will Wilson joins me to explore how far you can push testing… youtu.be/_xJ4maWhSNU

One of my favorite uses of llms so far has been migrating config. I wanted to play around with hyprland after using i3 for a long time. I pointed the LLM at my nixos config for i3 and it migrated everything without issue

At the end of the day, if you have pure deterministic code, you can make a lot of simplifying assumptions on when you need to compute stuff since you can easily cache anything.
