leoff··on What's functional programming all about? (2017)
Interesting how the post doesn't mention the word "side effect" once.

To me, all of this could be summarized by "no side effect".

leoff··on SpaceX Pulls Employees from Brazil, Discourages Travel There
How does Musk plan on winning with these escalations? He's effectively blacklisting himself from the country.

as a mechanical engineer, can confirm. also, e ≈ pi ≈ 3
leoff··on Helldivers 2 Removed from Purchase on Steam in over 150 Countries
I find the reaction to be appropriate, a large amount of people can't play the game anymore. What else would you expect? "I paid a considerable amount of money for the game and now I can't play it anymore, but the graphics were very nice on the small amount of time I played, 5 stars"?
leoff··on Show HN: I made a site to find top YouTube courses, bypassing expensive courses
Interesting idea. Some feedback - The UI doesn't look very good everywhere (text on the landing page has low contrast, awkward elements placement in the tool)

- Why are you restricting the product only for education? From your demo it seems like it could be used for anything? E.g finding animations, certain video styles Your real product seems to be a semantic search for Youtube

- You should return a list of videos, instead of a single one. Allow people to choose the one they like most

Otherwise, cool project, it's also not something I would pay for, but maybe some people would

why have a truck doing this? Couldn't this be a much lighter and efficient structure with just the camera and robot arm?
leoff··on Study: 61 UK firms tried a 4-day workweek and after a year, they still love it
> Of course employee are going to report happy

isn't this also about the firms loving it? If it's a win/win for both sides, what's the problem?

leoff··on Ask HN: Why is HN so often down?
It's very weird how most websites already figured out how to keep their services up under load, but a CRUD text-only forum, with an "elite community of techies", can't.

I would be curious to know what is the big challenge here.

leoff··on Extreme video compression with prediction using pre-trainded diffusion models
AI is always deterministic. We add noise to the models to get "non-deterministic" results, but if the noise and input is the same, the output is also the same.
leoff··on Show HN: Just Ship, a free and open source SvelteKit SaaS boilerplate
do you think this is always the case, or it's just your perspective as a dev?

could it be that someone from sales/marketing say that these things are only 20% of the work for them, and building the app is the 80%?

leoff··on Rook to XSS: How I hacked chess.com with a rookie exploit
He didn't mention the methods not involving monitoring the client. Most of them would involve monitoring it, yes.

- Response time

- Strength consistency within current game

- Strength consistency across all of user's games

- Is user switching windows

I bet these are already integrated in current cheat detection.

leoff··on Rook to XSS: How I hacked chess.com with a rookie exploit
> Any detection scheme based on extra information from the client could be defeated by running the chess engine on a separate computer

Response time and strength consistency could be detected regardless of having another computer.

If a person is always playing fast moves, or playing very consistently or very inconsistently good moves, they could be detected.

leoff··on Rook to XSS: How I hacked chess.com with a rookie exploit
> the only way to possibly detect cheaters

why would this be the only way? I can think of many different things you can do to detect cheaters

leoff··on The quiet death of Ello's big dreams
> I remember being rather underwhelmed by what they asked me to do

funny how people that say this are often the ones bombing the interview.

usually the ones who score well, are the ones that see how the simplicity of the given problem gives them room to show how well they understand the domain, and they appreciate it.

leoff··on When Random Isn't
I've also spent some time playing with TSM. I would login to WoW multiple times a day only to play on the AH.

I don't quite recall where from, but I had some price data, where I filtered the top X products that made the most volume (price * amount sold).

I then simply did something like "if the price is lower than Y% of the average, buy it. Don't sell the product for less than you bought it for."

Surprisingly this simple formula works very well and I made more gold than I've ever had. It was more than enough to pay for the monthly subscription and I even bought Overwatch using the I credits I got from it.

leoff··on High myopia is now the leading cause of blindness in Japan, China, and Taiwan
> But suddenly from 25, it started to reverse, losing about 0.5 dioptric per year.

So it got better and better, until it became myopia? Was there a point in the middle where you had normal vision?

leoff··on Is Software Getting Worse?
Most people and companies write software to make money.

If you are trying to optimize for this goal, does it really matter if your software is as effective as it's physically possible?

There's a certain threshold for performance your customers implicitly expect you to reach. If you're within this boundary, is it really worth to spend days coming up with a new inverse square root optimization instead of bringing more value to your customer with new features?

leoff··on Othello Is Solved?
> Imagine finding a pamphlet written by God that contains a listing of a perfect game of chess

How would you go to prove that this is the perfect game of chess, if you didn't explore all of it's possible sequences? If they did solve the game, there's no way around knowing all possible outcomes - starting from a fixed given position.

leoff··on LLMs playing chess are sensitive to how the position came to be
Isn't this the same for regular language?

If someone is telling something making grammar mistakes, it's likely that the next word will also contain a mistake, so the LLM reproduces it.

And to be fair, I also think that most humans also have this same sensitivity in chess. I've seen even super GMs needing extra effort to realize something like "oh, this opening is just like the Sicilian defense, but with an extra tempo for white", and then instantly "loading" mentally the top strategies for Sicilian defense, that they weren't considering before.
