I had little experience with Lisp until recently when I converted a few hundred lines of Lua to Fennel. I have a lot of experience with Python.

I've always been scared of Lisp syntax, but after just a little experience with it it all kind of fades away and it feels like an indentation-based language, while remaining very compact. Now I'm like "why aren't all higher-level languages lisps"?

Editor tooling definitely helps, but it's one of those "skill floor skill ceiling" ideas. Parenthesis-based syntax has a slightly higher "skill floor" (takes more effort to edit), but with editor tooling has a much higher "skill ceiling", where experts can move blocks at the level of syntax rather than characters. Even just vscode's new bracket highlighting and guides are a small feature but a big help to see structure.

Thanks for your comment! Ditto last time I ran Airflow locally it took like 5 Docker containers. Then I forgot about the project and for a while was furious at Docker for randomly taking 100% CPU. Then I realized it was because of the Airflow containers that would restart along with Docker. I didn't get much further with Airflow.

Dagster, on the other hand, seems to let you scale from using it locally as a library all the way to running on ECS/K8s etc. Along with that there's unfortunately a ton of complexity in setting it up but that's not Dagster's fault and it seems like Dagster works once you get it set up. Agree about it being young and there being some rough spots but it's got lots of good ideas. We were nearly done setting it up but got pulled off onto more urgent things, so I haven't run it in production yet. I'm glad to hear it worked well for you!

I'm bullish about Dagster nowadays. Though, I don't have a lot of experience with Airflow. Figured I'd ask if anyone has switched from Airflow to Dagster and has any comments?

No file previews yet? I'd stick with ranger or lf.

Agree, I've started replacing my `perl -pe s/.../.../g`s with `sd`. It seems it's actually slightly faster than the equivalent Perl for the same substitutions (which it should be since it does less).

Here’s what I do for that (aliased to ‘p’): https://github.com/kbd/setup/blob/d95653da5ab367b1e628b97537...

The only part I left out is that as part of my shell config I automatically alias all my short git aliases (as well as a few special cases). So “gcp” -> “git cp” etc.

If anyone cares, I do something similar with my git aliases: https://github.com/kbd/setup/blob/master/HOME/.config/git/co...

So, "ga" similarly gives a fuzzy finder of files to "git add" that are actually in git status, "gcp" lets me cherry pick one or more commits from a branch where both the branch and commits are picked with fzf, and so on.

The mistake that article makes (imo) is that "colorblindness" means at compile-time. i.e. you don't have to define both a sync and an async version of a function. Obviously async vs sync have different representations at run time.

I had thought of mentioning San Francisco. I didn’t because it’s an Apple-only choice but your comment makes me appreciate it more. Noto looks great. It seems like with these configurable fonts you can use the same face for body text and have it still look good in headings at a different weight.

As a programmer I have strong opinions about my monospace font, but if I want to make a UI or display very readable sans text what’s the best option? Roboto Flex? Inter?

What. I still play Super Hexagon occasionally and I’ve had that game on my phone for like 10 years.

I didn't realize the author of Janet was the author of Fennel, thanks for making the connection.

Never understand why people use “command runners” instead of just shell scripts.

Tried asdf but can’t stand the global shims. I only want it to work on a per-directory basis with direnv. I tried to follow the asdf-direnv instructions but IIRC still wound up with asdf’s shim directory in my global PATH, and it needed to install its own copy of direnv. Disappointing that asdf expects to take over my system like it does.

This tool isn't "news", it's been a staple of my environment for years, but it's trending so upvoted. I use fzf everywhere, it's greatly enhanced my workflow. Recommend fzf-tab to use fzf for zsh autocompletion.

No point in complaining to HN about this.

I haven't understood what the point is for a "task runner" over having a bin/ directory in the project with some shell scripts. If it's not going to do anything extra for you (like run commands according to a dependency tree like make), I don't see the point.

FWIW nu shell can be used for a lot of the same use-cases:

    $ echo "[1, 2, 3]" | nu -c 'cat | from json | to yaml'
    ---
    - 1
    - 2
    - 3
    
    $ echo '{"key": [1, 2, 3]}' | nu -c 'cat | from json | to yaml'
    ---
    key:
      - 1
      - 2
      - 3

Oh man, REBOL, blast from the past. If they had open-sourced it early instead of trying to promote a proprietary programming language we might talk about REBOL along with Python and Ruby. Instead, it's forgotten.

Very cool, hadn't heard about that tool. Do you think that's more powerful than simple shell scripts around HTTPie/xh/curlie?

Agree, after researching this a little while ago, those are the two best alternatives. Was bit by HTTPie not supporting HTTP2, but both of those do. xh (Rust) is also faster (yes, in practice, try some large responses) than HTTPie (Python).

Edit: also just want to say, in a world where "the current GUI tool du-jour got bloated and this one has hidden behavior when you right click this button...", I much prefer command line tools where possible!

Doesn't a lambda based on a docker container incur container startup time, whereas if you use one of their language-specific SDKs you don't?

Yeah so it’s still not first-class in the language and off by default. Thanks for the links.

So what is the status of Crystal multi-core now? My understanding was that Crystal enables Go-like concurrency (green threads communicating over channels) except they call "go" "spawn". Except it was still single-core and they were working on multi-core?

From what I've seen I really like Crystal. It has good ideas and they're working on a dang REPL! I'd like if it took over some of Go's share, and I'd like to not have to say "but they're still working on multi-core".

Personally I'd prefer to use open-source tools if possible.

For Podman vs Rancher, what are pros and cons? If you only use Docker from the command line is there any reason to use Rancher?

Sheesh so fast... scary. RIP.

Yes that is indeed the next most-frustrating thing about Go! In the last Go language survey (https://go.dev/blog/survey2020-results), about 90% of people wanted generics and 60% of people want better error handling. So, one down, one to go.

Modern languages like Zig and Rust show how you can do "errors as values" way better. Zig has error returns and stack traces built in, there's no reason Go has to be so impoverished here.
