Today I'm announcing Botsman, https://t.co/aEW7v66PUP: my bot development platform for Telegram. It's a project I've been working on for a long time. Check it out!

For now it's in beta, but you already can login and receive a notification when it will become publicly available.

Decided to design a simple, yet (at least moderately) effective captcha.

Came up with an idea of using emojis instead of characters. Here's a demo: https://t.co/wh51FEYWQz

What do you think?

[Denis Olshin @denullru]

This is a port of Redis implementation, here’s an article describing the algorithm in more detail: https://t.co/WlocRfARDZ

I’ve added one little tweak from myself: for small sets (up to 1000) it can store the exact list of elements, which reduces the error in this range to 0.

[Denis Olshin @denullru]

Published yet another Nim library!

This one is a HyperLogLog data structure implementation. It allows to estimate the number of unique elements in arbitrarily large sets, using just 12kb of memory. No dependencies, just a single Nim file :)

I decided not to stop there and ported yet another library called Pigo to Nim.

It uses something called cascade binary classifiers to detect faces and facial landmarks on photos. I still don’t fully understand how that magic works, but here it is https://t.co/6E5SHrJM7Y #nimlang

[Denis Olshin @denullru]

Nim is a great language, however its community is still relatively small, so it lacks libraries for many tasks.

For example, I wanted to use perceptual hashes to find duplicate images, and couldn’t find a good package for that.

So I made my own: https://t.co/Jkoxnn3l1O #nimlang

[Denis Olshin @denullru]

It uses ideas from https://t.co/eO165WkC5T and from this post: https://t.co/zN64Vdkvzo (and also a basic histogram hash for a good measure)

For even better matching it would be nice to also implement SIFT/SURF. It would work much slower though.

But not for ⁦@denullru⁩ 😁🙏

@SmartControls @max_katz Задачи были настолько тонки и ювелирны, что о них не догадывались даже те, кто их ставил :)

@grishka11 @amima Исключительно эгоистических

Тебе, Гриша, вообще похер, какие там проблемы у других, как они свои риски оценивают, какие чувства испытывают

Всё только лично для тебя и только по твоим меркам, главное что Гришеньку уехавшие заставляют чувствовать себя виноватым

@elonmusk @spideycyp_155 @StonksReddit @Podolyak_M Why there’s a need for a referendum at all? Just because of Russia’s fake one? Does that mean that every country can come wherever it wants, claim that territory, and force UN to do a referendum about that? Do we really want to normalize that?

Previously I’ve generated a picture of “java developer”, as seen by Stable Diffusion network.

Now I did the same with DALL-E, and its equally hilarious:

а это у @denullru получилось, господи как же я ору

[Denis Olshin @denullru]

@SketchpunkLabs It's actually the same algorithm :)

Once you've reached some predefined area you do the same on the smaller scale — and now you have buildings instead of regions. After that you can just delete inner polygons (which are not touching any sides of the region), and that's it.

[Denis Olshin @denullru]

Tried following in @watawatabou footsteps by generating road networks using slightly modified polygon bisection algorithm. Looks promising so far!

[Denis Olshin @denullru]

@SketchpunkLabs Well, personally I based it just on this tweet https://t.co/2KkNxnbuac and this Patreon post: https://t.co/CKiiyrQSLC. The base idea is not too complicated, it's just splitting polygons in halves over and over again.

[Oleg Dolya @watawatabou]

This kind of polygon partitioning looks promising

@max_katz Беда в том, что негатив ко всем русским у украинцев конечно теперь есть (и пропагандисты на нём играют). Только негатив этот вполне ожидаемый, созданный самой Россией.

Странно ожидать, что многие станут любить тот народ, войска которого пришли в их страну и бомбят города :(

[Denis Olshin @denullru]

@Kira_Yarmysh @navalny Он просто несколько слов пропустил.

Это налог на вторжение в чужую независимость.

@grishka11 @amima @dolzmax Самое страшное, что по _некоторым мнениям_ Путин тоже
