The worst hobby

Bad things happen when you combine the self-affirming nature of beliefs with a habit of consuming lots of morally-charged content.

Many people make a daily routine of consuming large quantities of highly partisan content about “what’s going on” in “the” “world.” Enthusiasts of this hobby call it “staying informed,” and insist it isn’t just a personal habit but a civic duty.

This content consists of new beliefs (“news” for short) about what happened today or yesterday, presented with an authoritative tone and little moral ambiguity. They identify clear villains and clear implications. They often give instructions from hand-selected experts on how smart people should think about this.

Plenty of books and blogs will tell you how to develop your functional programming skills or teach you algorithms. But if you’re already pretty good at that stuff, you might be better off trying to become a more virtuous human being: more in control of your emotions, more able to hold your nerve in times of crisis, and humbler about the institutional power your technical knowledge grants you.

For me, this imagined audience is more important than getting it right. Which is why I write my blog posts with the wiki spirit. All these sites are pretty similar, in essence. Blog, wiki, digital garden, Zettelkasten, there’s not enough difference to draw lines. It’s all a question of intent, of culture, of belonging. The blog spirit is to write pages over time, and they disappear into the archive. The digital garden spirit is to write unfinished articles and papers, to be refined or not. The Zettelkasten spirit is to follow the trail of thoughts you thought and add new branches, small notes with new thoughts leading to more thoughts on new notes. And the wiki spirit is to write and edit online, to hit the Save button and then it’s live. There is no editor, there is no draft. Wiki is like brutalism in content management. I can see the page sources and the end result is obvious and full of that old web power. It’s not an app. The software has no idea of process. The wiki spirit is to open that window, write the text and hit save. And then I read it again, and edit it. And tomorrow, I read it again, and edit it. And next week, perhaps, I read it again, and edit it.

I no longer live in the Wiki Now. The pages are intended for future readers but they are not timeless. I add timestamps all over the place. The blog spirit is strong. The pages do disappear into the great compost of thoughts. The archive gobbles them up. I do go back but I don’t rewrite the pages completely. I’m more likely to simply add a timestamp and some thoughts like I did on this page.

Хотя обычно дома рисовать очень просто — прямоугольник с building=yes, — на практике постоянно всплывают какие-то сложности. Danidin9, автор картинок про дома в Петербурге, наглядно объясняет

если в процессе обсуждения архитектуры вы пришли у выводу, что в проекте потребуется настоящее горизонтальное масштабирование — вам не обойтись без конечных автоматов (так-то лучше вообще любую бизнес-логику строить именно на конечных автоматах, но в автономной системе можно подкостылить и без них, а вот в кластере — уже никак)

Так или иначе, если вы хотите оказаться готовым отмасштабироваться в горизонталь — стройте критические процессы на конечных автоматах и полностью асинхронно

Зато асинхронные взаимодействия поверх FSM — сделают в дальнейшем масштабирование безболезненным, ведь в такой парадигме не имеет никакого значения, на какой ноде выполнится код, отвечающий на запрос.

1. Go developers said they are more interested in AI/ML tooling that improves the quality, reliability, and performance of code they write, rather than writing code for them. An always-awake, never-busy expert “reviewer” might be one of the more helpful forms of AI developer assistance.

2. The top requests for improving toolchain warnings and errors were to make the messages more comprehensible and actionable; this sentiment was shared by developers of all experience levels, but was particularly strong among newer Go developers.

3. Our experiment with project templates (gonew) appears to solve critical problems for Go developers (especially developers new to Go) and does so in a way that matches their existing workflows for starting a new project. Based on these findings, we believe gonew can substantially reduce onboarding barriers for new Go developers and ease adoption of Go in organizations.

4. Three out of every four respondents work on Go software that also uses cloud services; this is evidence that developers see Go as a language for modern, cloud-based development.

5. Developer sentiment towards Go remains extremely positive, with 90% of survey respondents saying they felt satisfied while working with Go during the prior year.

Index the independent where predicates to improve hash join performance.

Indexing join predicates doesn’t improve hash join performance.

Indexing a hash join is independent of the join order.

Select fewer columns to improve hash join performance.

Hash joins do not need indexes on the join predicates. They use the hash table instead.
A hash join uses indexes only if the index supports the independent predicates.
Reduce the hash table size to improve performance; either horizontally (less rows) or vertically (less columns).
Hash joins cannot perform joins that have range conditions in the join predicates.

Rule of thumb: index for equality first—then for ranges.

This huge collection of non-scary optical illusions and fascinating visual phenomena emphasizes interactive exploration, beauty, and scientific explanation.
