That's really impressive, congratulations. It's nice to see novel applications of browser models.

That's... how the web works? You download things on demand. There are JS files larger than 7MB in the wild. They run on JIT engines that displayed severe CVEs over the years. PDFs, video running directly on special hardware encoders. T

It will affect jobs because the investment strategy works to degenerate the economy, but not because of the tech. Like a dog that barks at a truck and thinks he scared it away.

1. Find a problem that LLMs suck and you're good at. Then you'll have no choice but to enter the flow state. There's lots of those still. Portable shell programming is my favorite. Even the most capable models limp at it, but

Author here! This is a proof of concept for a tiny word -> palette model. I extracted data from all kinds of sources, and I plan to do more (Wikidata ingredient lists so I can color stuff like "burger" and "guacamole"

Have you ever tried to implement it?

One of the reasons for using dash is speed. It's so fast, it allows people to write programs that were not viable before. The pure shell C compiler is an example of that: https://gist.github.com/alganet/2b89c4368f8

Reminds me of https://www.opensourceecology.org/ , but way more low tech. One could actually try the Open Source Low Tech designs without having a small fortune to spare or gathering a considerable community to cooperate.

Here's how I deal with it using feature detection: case "$({ printf %b "\\061" || print -r -- 2 || echo -n -e "\\063" || command -p printf %b "\\064"; } 2>&#x2

Nope, implementors are worried about shaping the spec (which iterates much faster than POSIX) and the overall community around JS has plenty of portability solutions. That simply doesn't happen with portable shell script. There's

You shouldn't. You should audit the tool. It's open source, and I offer build checksums for reproducibility, it's made to be auditable.

That is another can of worms. For now, I'm worried only about the shell interpreter and builtins. `echo` in most shells is not `/bin/echo`, it's actually an internal implementation (external echo means forking at every

yash also has something similar, ECHO_STYLE var. https://magicant.github.io/yash/doc/_echo.html Additionally, the ksh family has `print`, which solves some of the issues. And the story repeats all over again, each

I honestly don't know! What I know is that there is an intersection of features that work with polyfills and tweaks in all shells. That intersection has a lot of the spec, but also has a lot that is not specified anywhere. I started to

ksh2020 is `v-` based, the repo I mentioned is an `u+` fork with backports from the failed attempt. Most notably, it doesn't change the build system. It's what Debian and Fedora use, so AT&T doesn't matter anymore. Real-w

Can you imagine? Using that fancy new gen JavaScript today? Oh wait, that's exactly babel's headline! It's just so old now that people don't need to say what it does. Actually funny that the spec drift got solved by poly

I particularly like ksh93. It's a virtual machine, which makes it super fast for a lot of scenarios. The ksh family is my personal favorite, in particular mksh and ksh93. Both with excelent feature sets. I even made a platformer game t

These are all in the shell-versions toolkit I recommended. docker run -it --rm alganet/shell-versions:all /opt/mksh_R59c/bin/mksh -c 'echo $KSH_VERSION' docker run -it --rm alganet/shell-ver

The post is not about shell differences, there's too many of them. It's about portability. I want users to test instead of rote memorizing. And I'm giving them tools: docker run --rm alganet/shell-versions:all -c &

Most shell families precede the spec. Both bash and ksh had features at the time the spec was written that are not in it. It's weird. My main point is that following the spec doesn't guarantee shell scripts will be portable, which

They are the same, kinda! ash and dash are from the Almquist family. https://en.wikipedia.org/wiki/Almquist_shell It's just poetic license.

No one says "Let's write ECMAScript for portability". If someone did, I would probably be writing about that too.

by gaigalas 4mo ago
You can target POSIX if you want to, but doing that doesn't guarantee shell scripts will work. The blog post stresses this, the difference between POSIX and portability. If you want portability, testing is better for now. One of the go

The spec is not that good. `local` for example is present in many shells (almost all of them), but they decided to leave it out uniquely because of ksh93 (scope is different). It became undefined behavior. When the spec was written, ksh was

Author here. It definitely builds outside docker. It's a musl-cross-make toolchain, you can procure the dependencies locally if you don't like the Docker recipes. Feel free to open an issue if you feel like that's a challenge
