Wollte eine Funktion schreiben, die das Zeichnen wie mit einem Bleistift oder so ermöglichen soll.

Einen Parameter falsch gesetzt, heraus kam das. Manchmal sind Glitches einfach was Schönes.

So jetzt Artemis II Landung schauen!

Just debugged a test which was failing because it was running in "sloppy mode" (not `'use strict';`).

What year is it?

tl;dr Using https://thi.ng/column-store to accelerate tag intersection queries by a factor of 880x...

Working on the static website generator/export plugin for my personal knowledge tool has been one of the main projects this past month. A key part of this setup is tagging, not just simple flat keywords/categories, but actually treating tags as sets. The system doesn't just allow browsing content by a single tag, but also supports adding (or removing) tags to narrow or widen the current topic. E.g. The combination of "3d + geometry + typescript" would select only works which have all of these three tags...

In the local version of my tool there's no limit to the number of tags (and it also supports tag negation), but for the static site generation I have to limit the set size (due to combinatoric explosion) and pre-compute all possible permutations, then create HTML documents for each these individual combinations which actually produce results.

So far I'm having ~400 unique tags in use, meaning if I want to aim for a max set size of 3, there're theoretically ~64,000,000 possibilities to check[1]! For the roughly 3500 content items used for testing, a naive JS approach to filter the result array and only retain items matching the entire current permutation is so extremely slow, that I stopped the process after 3.5 minutes just for the first 250k (aka 0.4%) of the 64 million permutations, i.e. at that rate the full process would have taken ~15 hours, pretty slow for a SSG... :)

Naive approach 🫣:

```
permutation = ["3d", "geometry", "typescript"]
results.filter(item => permutation.every(tag => item.tags.includes(tag)))
```

But since I'm using https://thi.ng/column-store as my database, such queries can be optimized by a few magnitudes, since here these intersection queries are applied only to bitfields (explained in the pkg readme). This results in all 64+ million permutations being processed in just 62 seconds (1+ million per second). Quite the difference, i.e. ~880x faster than the above approach!

Also, of these 64 million initial possibilities, there're fewer unique ones (excluding duplicates and ignoring ordering), and currently only ~24,000 are actually producing a result. Still, that's 24,000 index pages to generate & host and it's, of course, far, far too much!

So I will have to also spend more effort curating and severely reducing the tag vocabulary, at least the subset used for the website. On the other hand, I think this system will really help with browsing this large body/archive of work much more meaningfully than the boring single-tag/category approach most websites are offering. And it will do so without any backend (other than file hosting)...

[1] Permutations = 400 + 400^2 + 400^3

Как я автоматизировал управление информацией и оптимизировал рабочие процессы. История Sapiens OS

Если вы ведете несколько проектов одновременно, вы знаете проблему управления информацией. Мысль пришла в голову — записал куда-то. Через месяц пытаешься вспомнить: где это было? Сохранил в папке где-то на компьютере? В заметках телефона? В рабочем чате или личных сообщениях? Если не нашел — идея ушла. Или осталась, но найти её — отдельный квест и потеря времени, которое хотелось бы потратить с пользой, а не на поиски. Со мной так происходило постоянно. Статьи и доклады по учёбе, отчёты по работе, технические заметки по разрабатываемому ПО, ссылки на полезные ресурсы, голосовые идеи по дороге на работу, полезные фото — всё в разных местах, без структуры, без связей. Изначально я пытался найти для себя идеальный инструмент. Notion, Obsidian, Evernote — ни один не решал мою задачу в комплексе: быстро сохранить мысль, не потерять её, а потом легко найти и связать с другими. Поэтому я написал свою систему. Статья — не «продажа курса» и не «уникальный продукт». Это описание того, как я решал свои задачи, какие решения принимал и что из этого вышло. Если вы тоже теряете время при поиске нужной информации — возможно, найдёте здесь что-то полезное.
