I'm looking for a remote Rust/Elixir role (EU-friendly timezones, US East is ok).

I have 7 years of #rustlang, 9 years of #elixirlang, 20+ years of #linux.

I have over 20 years of experience as a professional developer, and I've been working remotely for 12 years.

Hi Elixir friends,
After 3 years on Hologram full-time (transpiles Elixir to the browser), I'm at a crossroads.

60+ hr weeks balancing contracts & dev isn't sustainable.
Where we are & how you can help: hologram.page/blog/seeking...

Even sharing helps 💜

The mac will occasionally just kinda forget that it has an audio jack and that port won't be recognized. So, no music from my speakers. Can plug them into the audio port on my microphone and they work, so it's not the speakers.

Needs a reboot to fix.

Oh fun. Cloudflare is down. And I wondered already why my CI is failing (it can't download ObanPro which is cached by them)

This. And all framed as “not taking sides” or “jumping to conclusions.” Most of the upset with RC was about lack of comms, kicking out people on GitHub, and platforming DHH, none of which have been sufficiently addressed.

Ruby community: Look, we can be angry about what's happening, we can raise our complaints, but under no circumstances should anyone _ever_ harass someone's families, coworkers, or friends.

That is completely unacceptable, and wholly against the ethos of the language. We must do better.

the reason I advocate for projects to have a code of conduct is because harassment is never okay. not only is harassment never okay, harassing families and coworkers is even worse. get out of here with that.

It's incredible how this whole thing has cut to literally every important cultural and political question in OSS.

These are the big questions, the values you build communities around. We should be clear about the things we believe. We coasted on the status quo and differences are now clear.
