0x264··on Claude Code's "Don't Ask Again" exposes passwords in 1,122 public GitHub files
Vibe coders don't review code, even if and when published to a public repo.
0x264··on Cuis: The Modern Smalltalk-80
When using so called OOP languages I specifically avoid inheritance, and in fact I think it's the worst aspect of it. In any case, I tend not to include inheritance into the definition of object orientation.
0x264··on SDF Public Access Unix System
Thank you for mentioning those! I saw both Robotech and Macross Plus (in French) when I was a teenager. I still think about the SDF more often I would admit and the soundtrack is a regular occurrence in my work playlist :)
0x264··on Dating: A mysterious constellation of facts
The secretary problem is a bad way to formalise the problem of dating and the stopping rule doesn't work in that context, for a very simple reason.

The secretary problem is a solution to the problem of having to make repeated choices. In essence it's a solution to the problem of having to choose a secretary every morning for the day. You can even say it's a solution to the problem of a computer process spending a few seconds consuming an infinite stream at the top of every hour for the next hour. It's not a solution to the problem of making a (hopefully) unique choice.

0x264··on S.A.R.C.A.S.M: Slightly Annoying Rubik's Cube Automatic Solving Machine
> I don’t know really how ppl that solve it fast accomplish getting to that level

Just like everything else in life, they do it really slow and with lots and lots and lots of errors at first, but (and this is where the magic happens) keep doing it, training hours a day or their entire week ends, for years.

0x264··on Advent of Code 2025: Number of puzzles reduce from 25 to 12 for the first time
On your CV ? Has any recruiter or hiring manager ever commented on it, or said the mention gave you an advantage ?
0x264··on Advent of Code 2025: Number of puzzles reduce from 25 to 12 for the first time
You can definitively play like that if you want to. At day 2n (n > 0) you do the puzzle of day n.
0x264··on Karpathy on DeepSeek-OCR paper: Are pixels better inputs to LLMs than text?
JavaScript code and Haskell code ultimately both get turned into instructions for a microprocessor, so there really isn't much of a difference between both.
0x264··on Show HN: Lingo – A linguistic database in Rust with nanosecond-level performance
Yep, another developer enthusiastically proposing mmap as an "easy win" for database design, when in reality it often causes hard-to-debug correctness and performance problems.
0x264··on Show HN: Amber – better Beeper, a modern all-in-one messenger
Yes, pictures of the user interface will help a lot. Thanks!
0x264··on An engineer's perspective on hiring
The situation is not going to improve as long as business stakeholders and engineering managers (some closer to MBAs than actual engineers) think of software engineers as construction workers. They think we are fungible, they don't understand the craft of programming etc, and have very short term mindsets. Took me a while but then I realised that I needed to interview my prospective employers as much as they were interviewing me, and to just ignore those not worth working for.
0x264··on VPN use surges in UK as new online safety rules kick in
No they can't. Myself, and quite a few other people, need it for work.
0x264··on Creepy Study Suggests AI Is the Reason We've Never Found Aliens
I would imagine that the alien civilisations would also make that kind of studies, and pre-emptively prevent the extinction scenario from happening.
0x264··on Data structures as topological spaces (2002) [pdf]
That's correct. It's (and they are) French.
0x264··on Advent of Code 2023 is nigh
> like chores by the 10th problem or so and I drop out

That they get so involved is the reason I participate (despite also working at the same time). I love the fact that the difficulty starts low and then goes up to levels where I feel really challenged. It's a month (well, 25 days) commitment which pays off the entire 11 other months for me :)

0x264··on MS Teams channels cannot contain MS-DOS device names
Set of related trades.
0x264··on Functions are vectors
Hi thaumasiotes, Mathematician here, and somewhow interested in this discussion. I am curious of your definition of full_sqrt, what would be the value of full_sqrt(-3) ?
0x264··on From Swiping to Sexting: The Gender Divide in American Dating and Relationships
It's a completely factual statement, and relevant in the context of the article. It doesn't claim that the same cannot be observed, or doesn't happen, somewhere else.
0x264··on [dead]
As somebody currently learning Rust, I totally echo this sentiment.
0x264··on Cheat sheet for if I'm gone
Have an electronic version of it (the main version)

1. Update it every year or so, and 2. Everytime you update it you print a copy version and distribute that as needed.

0x264··on A high-dimensional sphere spilling out of a high-dimensional cube
Oh yes, they do :)
0x264··on Ask HN: What are the best-designed things you've ever used?
BitTorrent is 20 years old, IPFS only 6. So, might just come down to familiarity. Definitively many more people, even outside tech crowd, have heard of BitTorrent whereas IPFS is still mostly unknown.
0x264··on What is Chia cryptocurrency and why is it bad news for hard drives?
There always is a simple explanation:

Resulting from (1) removing irrelevant details (details crucial for an implementation, but irrelevant for an initial mental model) and (2) making use of analogies built around already known concepts.

"Complex maths" is never an excuse to not find that explanation.

Disclaimer: I am a pure mathematician.

0x264··on Show HN: Squirrelbyte – a SQLite-based JSON document server
Somebody is using a database (sqlite in this case) to store JSON objects. There is nothing strange or unusual here.

When doing this, though, the problem is that it's more difficult to run search queries with the same expressiveness as we would otherwise do had the data been properly "unfolded" into many columns of a relational database.

This tool allows to make such expressive requests. This is very useful.

Interestingly the search query itself is expressed as a JSON object (this is a design choice, it could or could not have ben the case. In any case it's cute.)

0x264··on The Kitten Programming Language
It's stack based. Written like RPN (Reverse Polish Notation).

Hehehe
0x264··on Neil Armstrong's reply to a Moon landing skeptic
There is a difference between, on one side, questioning one's understanding of the universe, which is how science works and progress and, on the other side, being unable to accept facts, which is where moon landing skeptics are.

0x264··on Show HN: Space Battle: a strategy game with only a HTTP interface
Answer to the questions in order: (1) Not enough, not many for the moment, and (2) I have just noticed somebody else on this thread made a visualiser for the game map. But a real time view of user fleets is yet to be made. Because the view of each user is partial (their knowledge/visibility of the game depends on the probing activity of their own fleet), the only real visualiser would be a "God view" that the game master (who has access to all the backend data could make), but that view would not be shared with the players as this would give them an unfair advantage.
