To derive "The XOR trick" I think both *associativity* and communitativity are needed.

That is, one should also prove a ^ (b ^ c) = (a ^ b) ^ c. Instinctive, but non-trivial.

Show HN: VSCode-remote-glibc-patch – Patch legacy Linux to use VSCode Remote

Looks cursed to me.

But TIL dollar sign $ is also valid character for identifiers.

I'm with you. Sometimes the symbols are ambiguous and totally unreadable.

An example is >>=, which is "inplace shr" in some languages, but "monad bind" in others. A unified ligature for >>= really confuses me.

> CJK line breaking is awful

It's not true for Chinese. Chinese allows line breaks after any characters.

Meanwhile, another trend among Chinese teenagers is the use of Pinyin initials to replace Chinese words. For example, 永远的神 (pinyin: Yǒngyuǎn de shén), a meme used to praise something, is often written as "yyds."

These teens have become accustomed to reading and writing sentences composed of such acronyms, and they even use them in real-life conversations—much to the annoyance of cultural conservatives. This phenomenon highlights how online communication can influence offline speech patterns.

You may self-host a vaultwarden to serve TOTP and install a website extension. To login you just click the extension for code and no need for any mobile app.

Truly. But at first sight I couldn't parse the comma as anything else except a delimiter :(

I mistakenly think the guy took over a year to boot Linux/4004 due to the comma in the post title.

(I was aware that comma represents decimal point in some regions, just didn't get this in the first place.)

Is this real?

You can run the demo locally following the Usage part. Currently the WASM shaper feature is not enabled in any browser, so the demo won't work in web pages.

The handwriting in fact consists of multiple "tiny black box" glyphs, similar to pixels in traditional rendering. The program takes the text (e.g., "Hello world") as input, and works out the (x, y) locations of these block boxes.

I didn't train the model myself. A pretrained model is adopted from another repo [0].

The answer is "no why", just for fun :) Though I learned a lot about how to stuff an NN model in a WASM binary and some tricks to optimize performance.

The project must be tested in an application linked against libharfbuzz with WASM shaper enabled. Since it's not easy to build a library like this, I make a Docker image which contains both the ttf file and a modified gedit, so that anyone can test the project with a single command.

Yes. The program actually includes an ONNX runtime, which uses SIMD to accelerate NN inference.
