Why not slow down?

Why does it have to be frenetic? Why not just slow down? I suppose you could, but I don’t recommend it. It’s just such a miserable experience to spend your day close-reading LLM output: carefully chewing and savoring each morsel of slop. It’s far less unpleasant to skim through quickly and pick out the useful nuggets of content.

Couldn’t you simply do more of the work by hand? It’s unfortunately true that tech is high-pressure these days. If you’ve got the time and space to work more slowly, that’s great! But when your company gives you a “solve this task ten times more quickly” button, you are heavily incentivized to use it as much as possible, or risk being outcompeted by your peers.

Damn...

We backed up Spotify (metadata and music files). It’s distributed in bulk torrents (~300TB). It’s the world’s first “preservation archive” for music which is fully open (meaning it can easily be mirrored by anyone with enough disk space), with 86 million music files, representing around 99.6% of listens.

The more time you spend designing systems, the more paranoid you get about things going wrong

Some of Stephen Wolfram’s “productivity hacks” to make his days and projects more productive. Daily life, desk environment, outside the office, presentation setup, filesystem organization, Wolfram Notebook systems, databases, personal analytics.

I especially like the treadmill.

There is a single advice I would give to anyone writing software, and specially to great devs : Always optimize your code for your most junior developers. I agree that it is not a very popular advice, but it is the one that, in my experience, give the biggest bang for the buck.

Таймкод 40:40: Кого из российских чиновников стоит слушать?

Вот еще одна иллюстрация на тему «психология гавно». Увидел в 2024 году в инстаграме психолога, борющегося с «когнитивными искажениями» и утверждающего, что фундаментальная ошибка атрибуции — это «Самая Тупая Ошибка Мышления».

Максим Ильяхов разговаривает с гинекологом

Макс на Луне. Одна из моих любимых поинт-н-клик игр. С милой анимацией и озвучкой на нескольких языках.

Также есть и другие части, но эта мне нравится особенно.

By wrapping errors and building well-formatted error messages, we can keep better track of where errors are happening. I often just add the name of the function being called to my error messages, but we can make the message say whatever we want. For example, I’ll often include parameter information in the error so I know which inputs caused the error.

Если для придания уверенности в себе вам нужен карманный ствол — я рекомендую обратиться к психологу. Это дурной симптом.

Беру любой JSON и вижу, как его можно упростить, убрав лишнюю вложенность. Вдвойне обидно, что на эту вложенность кто-то тратил время, а она не нужна!

Minimizing your keyboard layout is a slippery slope.
34-keys has been reasonably comfortable to use, for both prose and program. My palms do not move across the desk at all, as I reach for keys. I mostly write Rust and Bash, and my layout has evolved to accomodate special characters from their grammars (angled brackets and hyphens, specifically). If you are on a similar journey, I would suggest focusing on accuracy and comfort over speed. Speed comes with time.

Везде речь о флетвайте. В случае сетей я указываю адреса только тех точек, в которых я был, и при этом там хорошо. Во всех местах из этого списка дают воду, если попросить. Цену указал, где помню.
