> Any software developers here? What language/tech are you all using or just simply ove?

I'm a software developer (though I'm not wild about that term). I've released projects in #bash, #javascript, and #rust (which has been my main focus lately). I've also played around a fair bit with #python, #c, #elisp, #vimscript, and #racket.

Of those, Rust and Racket are far and away my favorites

Does anyone have that image of bad code that was going around the fediverse a couple of months ago? I don't remember the details, but I think it was #javascript and involved authentication

Maybe it would be worth a try to convince the developers of the tools which minify JS, to keep the licence tag? This way it would be really as easy as just putting a licence tag on each source file, which you should do anyway. #JavaScript #FreeSoftware

I made my homepage #librejs compliant, also to get some firsthand experience. While it was quite easy for my small homepage I'm still not sure if it works for large websites. #JavaScript #FreeSoftware

Why is #Python growing so quickly?

From my (web-dev-ish) perspective, I see Python get used for server-side code (where #javaScript/Node and #golang are eating into its use) and CLI tools (where golang and, to a lesser degree, #rust are rising). Given that, I would have thought Python would be in a slow but steady decline.

Instead, it's the fastest growing language of them all: https://stackoverflow.blog/2017/09/06/incredible-growth-python/

What projects are fueling this growth? Am I wrong about web, or missing something else?

Just finished Mathias Buus and Emil Bay’s absolutely marvellous “Learn To Crypto” workshop and feeling so much more confident with the basic primitives of sodium-native.

Can’t recommend it enough.

Find/take it online here:

You can also check out my work files if you get stuck (I tagged the later examples):

Yeah, I *generally* agree, though walking through that logic can lead to some weird places.

In #rust, `true ^ false` evaluates to `true` because Rust implements `^` as the XOR operator for the `bool` type—no casting involved at all.

In #javascript—which *doesn't* have an XOR for booleans, `true ^ false` *also* evaluates to `true` (in a conditional), because JS casts it to `1 ^ 0`, which is `1`, which is cast to `true`.

Does that mean that `^` is good code in Rust but bad in JS?

@Shamar @how I think that it would get better if we free our #JavaScript according to #LibreJS and use #ProgressiveEnhancement, so most stuff can be done without #JS, even forms, no need for #CAPTCHA. See https://mikegerwitz.com/2017/06/Don-t-force-me-to-use-your-tools-on-the-Web (by @mikegerwitz ) and also combine http://ezinearticles.com/?Captchas-Considered-Harmful---Why-Captchas-Are-Bad-And-How-You-Can-Do-Better&id=1104207 with server-side scripting and #CSS.

- Have a deeply recursive function in #javaScript
- Rewrite it naively in #rust
- Compile with `cargo build --release`
- Notice it is now 10× *slower*

…hmm, that wasn't what I expected!

> I was that dweeb that always reminded everyone "actually infinity is not a number" in elementary school. I'm doing much better now.

Is that because you realized `Infinity !== NaN`?

#javascript

@kogumanomisha I was all set to start talking about the power of #rust or the versatilely of #javaScript or the expressiveness of #python until I realized that you weren't talking about *that* sort of language…

I've been listening to three programming-language podcasts lately.

The #rust one ends with the host personally thanking all of his patreon supporters.

The #ruby one ends with the hosts thanking their corporate employer for continuing to sponsor the show.

The #javascript one ends with a "shameless plugs" segment where the hosts try to sell you their latest for-profit JS courses.

Obviously it'd be absurd to judge entire language ecosystems with a sample size of 1 each, but …
