ZeljkoS··on Vals.ai Benchmark – International Olympiad in Informatics
"The two leaders score 100% on 2026 even though the contest ran after their training cutoffs, so recency alone does not cap performance."
ZeljkoS··on Show HN: TamedTable, AI ETL in Natural Language
Great!

If all plan queries are deterministic, the "Save recipe as Python" action saves the entire process as a deterministic script:

https://www.tamedtable.com/#save-py

Honestly, you are probably not the target user, as you seem familiar with data cleanup scripts and AI agents. I think the target users would be:

A) Non-technical people in your org who clean data by hand because they don't know to automate it.

B) Technical people who want to test multiple queries and preview transformations before generating an AI-driven transformation flow (and are OK with it).

But, it writes an execution plan :) Example here:

https://github.com/ZSvedic/TamedTable/blob/main/spec/test-ca...

And if an action can be done deterministically, then JS code will be generated:

https://github.com/ZSvedic/TamedTable/blob/main/spec/test-ca...

If data cleanup needs to be deterministic, why is so much of it done by humans? Two humans also won't normalize the same table in the same way. The main thesis is that AI data cleanup is cheaper and less mistake-prone than the same work done by a bored intern.

ZeljkoS··on Claude Code runs Git reset –hard origin/main against project repo every 10 mins
Update from the author: https://github.com/anthropics/claude-code/issues/40710#issue...

"Update: Root cause found — this was a bug in a tool I built that was running locally for testing, not Claude Code.

When the tool's configuration pointed at a local working directory, it would hard-reset that directory every poll cycle to reflect the remote — destroying all uncommitted changes to tracked files, exactly as described in the issue."

ZeljkoS··on ChatGPT Atlas

1. Turn on browser memories Allow ChatGPT to remember useful details as you browse to give smarter responses and proactive suggestions. You're in control - memories stay private.

2. Ask ChatGPT - on any website Open the ChatGPT sidebar on any website to summarize, explain, or handle tasks - right next to what you're browsing.

My guess is that many ChatGPT Free users will make it their default browser just because of (4) — to extend their limits. Creative :)

ZeljkoS··on Defeating Nondeterminism in LLM Inference
For "bug" reproduction purposes. It is easier to debug a model if the same string always produces the same incorrect or strange LLM output, not every 100th time you run it.
ZeljkoS··on Algebraic Effects in Practice with Flix
OCaml got experimental algebraic effects in version 5.0 (December 2022). Here is a tutorial: https://github.com/tanelso2/ocaml-effects-tutorial

Also from the tutorial: "Unlike Eff, Koka, Links, and other languages that support effect handlers, effects in Multicore OCaml are unchecked currently. A program that does not handle a performed effect fails with a runtime error."

ZeljkoS··on Flix – A powerful effect-oriented programming language
Flix FAQ (https://flix.dev/faq/) starts normal, but becomes increasingly more hilarious towards the end :D

Some gems:

---

Q: Wait, division by zero is zero, really?

A: Yes. But focusing on this is a bit like focusing on the color of the seats in a spacecraft.

---

Q: "This site requires JavaScript"

A: People who have criticized the website for using JavaScript: [1], [2], [3], [4], [5].

People who have offered to help refactor the site to use static html: 0.

---

Q: I was disappointed to learn that Flix has feature X instead of my favorite feature Y.

A: We are deeply sorry to have let you down.

---

Q: This is – by far – the worst syntax I have ever seen in a functional language. Semicolons, braces, symbolic soup, et al. It is like if Scala, Java and Haskell had a one night stand in the center of Chernobyl.

A: Quite an achievement, wouldn't you say?

ZeljkoS··on S1: A $6 R1 competitor?
We have a partial understanding of why distillation works—it is explained by The Lottery Ticket Hypothesis (https://arxiv.org/abs/1803.03635). But if I am understanding correctly, that doesn't mean you can train a smaller network from scratch. You need a lot of randomness in the initial large network, for some neurons to have "winning" states. Then you can distill those winning subsystems to a smaller network.

Note that similar process happens with human brain, it is called Synaptic pruning (https://en.wikipedia.org/wiki/Synaptic_pruning). Relevant quote from Wikipedia (https://en.wikipedia.org/wiki/Neuron#Connectivity): "It has been estimated that the brain of a three-year-old child has about 10^15 synapses (1 quadrillion). This number declines with age, stabilizing by adulthood. Estimates vary for an adult, ranging from 10^14 to 5x10^14 synapses (100 to 500 trillion)."

ZeljkoS··on YouTube embeds are heavy and it’s fixable
Not mentioned in the article, one of the main reasons to ALWAYS do this is SEO. Regardless if users will play the video or not, web crawlers will not play the video and Google will penalize your SEO ranking if you use official Google's YouTube embed :D
