With a ham radio license that still works wonderfully (if the solar Wechselrichter of the neighborhood doesn’t fuck up SNR in HF band too much)

Got it, thx

Looks cool. Out of curiosity: why do you spin up a GenServer for sending a single packet and waiting for the reply? Wouldn’t that be something you can do directly in the calling process?

That's interesting, indeed surprising that the "fast" one is consistently slower. Love the example

It’s awesome to see the level of dedication and professionalism how you all (with the umbrella of the ErlEF‘s CNA) are handling all of that. Big hat tip.

Wanted to add some snarky joke about „making Elixir more known to the world“ via vulnerabilities and CVEs, but didn’t find the right words 🤪

Interesting. Would be interesting to have a short doc on how patterns in the other WS(S) clients would translate to your lib. Unifying on Req/Mint/Finch of everything client sounds compelling

Interesting, never seen that glitch on iOS

Nice article, my immediate question "Where can I find Result" pointed me to your nice "Fey" library, very cool... Makes the F#-lover in me tick...
October 4, 2025 at 12:50 PM
That looks awesome
October 2, 2025 at 5:01 PM
Absolutely. The question is whether that particular aspect is a an advantage or not. That only works if you run on a single machine, and can be friggin dangerous. Also, Erlang/Elixir would have hot-code-reloading, but that also needs some thinking

Congrats, what an achievement

Ham radio was a topic during Goatmire as well, @peterullrich.com currently studying for his Dutch license… Vy 73, DG5EAW

Wait, what? Really?!?

BTW, I just installed Erlang globally (otp_win64_28.1.exe) from erlang.org, and that also works without issue. I believe something in your local environment is mixed up... Both user-directory installation (and global machine-wide installation with spaces in path) work without an issue.

Error code 5 looks like some sort of access permission issue. I like to install Erlang/Elixir via the the scripts from elixir-install.org, no hassle. Anyway, if the problem persists, you might also give livebook.dev a shot, notebooks where you can have Erlang code cells as well.
September 21, 2025 at 8:40 AM
In installed Erlang multiple time on Win 10 and 11 over the last years, and stuff like a space in ‚Program Files‘ had never been an issue, that’s why I’m confused
September 21, 2025 at 7:00 AM
That is strange. Can’t repro currently, but I would suggest to try the Erlang portion of this as well, pure command line via Powershell
