Harnessing Chat Data for Semantic Q&A Search | April 30 2026, 04:05

In one evening, I created a simple utility that extracts the Natural Language Processing chat for a year and a half – there are 65,000 messages, and converts it into question-answer pairs with semantic search available. Clicking on a search result (on the left) opens the dialogue in the chat. The messages that are responses to the question are highlighted. And at the top, the original phrasing of the question is highlighted as well.

How it works: the system assumes that people mainly reply to messages that are relatively close in the past. If several replies are made to one message, then it is likely useful and caught the interest of others in the chat. The system takes messages starting from the one many have replied to, ending with the last in the reply-to chain – and among such messages, it selects those that have at least 3 reply-tos to the original question. In essence, it cuts a piece from the chat starting with a popular question so that after the bottom cut, most likely, irrelevant content follows. Such blocks can overlap each other – for example, if someone asked a question while others were replying to something else.

So, if user A asked what the weather was like, and they received answers like “good,” “bad,” “rain,” and there were five messages without a reply-to, and then someone replied to “rain” with the question “why rain”, and five more people replied to this question, then the first question about the weather makes it into the system – the piece ends with 13 messages.

Afterwards, these pieces are summarized into question-answer pairs.

It turns out quite cool.

P.S. In the screenshot, the search query has nothing to do with the search result because I foolishly took the screenshot after I changed the query but before I hit send.

Peripheral Vision: Unveiling Optical Illusions in News Apps | April 29 2026, 17:56

I’m trying to figure out if it’s just me or do other people experience this too 🙂 if you look anywhere except at the word “Omurbekova”, the line highlighted in red in the second screenshot (which is actually white) is distinctly visible in your peripheral vision. But as soon as you shift your gaze directly to it, the line disappears. That is, it’s only visible peripherally. Share your experiences 🙂

Misadventures in Keyboard Layouts: Searching for Gremlin, Finding Surprises | April 28 2026, 20:33

This is me typing the word gremlin, without switching the keyboard layout. Wanted to read about the query language for graph databases, need it for work. Google surprises, it does surprise

Rethinking Karma: A Crafted Tale of Redemption and Survival | April 27 2026, 21:37

An interesting interview with Ilya Remeslo by Sobchak. But if I were Ilya’s political technologist, I would have suggested a much more coherent story: as if, one morning, he woke up, looked back at the past, and decided to fix his karma, rather than drown. Everything I did before that morning – my past life. We can talk about it, but for me, it is a closed page, I am ashamed of it, and if someday they decide to punish me for it – it would be fair, I am ready. If they punish for today’s stance – it would be unjust, but I am ready nonetheless. Either option is better than drowning, hence the boldness. Such a story would have been much more coherent, and it doesn’t matter if it has anything to do with reality.

From realistic explanations, I keep to myself that the guy was genuinely threatened with death, someone close to the powers that be, unclear why, the reasons could be numerous, and from all the options on what to do, this one had the best chances of staying alive because if the threat is realized now, the ratings will drop even more. Well, if he is jailed, it’s almost state protection from threats.

There’s one more thing. Possibly, this individual made it known to the right people that if he is locked up, some very serious dirt will immediately go to the media, but if nothing happens to him, there will be silence.

Colorful Climbing: A Fun Indoor Adventure with Masha | April 27 2026, 15:03

Went to the mountains with Masha. Yellow paths over yellow, red over red. The organizers should put a box of candies at the top. Found out that the muscles in my fingers are non-existent, and the rest hurt the next day. Cool experience (not the first time)
