Can anyone help work out what characteristics diode D4 should have in this circuit diagram for a wind generator control board...?

My initial guess is that it's protecting U1 (a voltage regulator?) from discharge currents from C4. Does that sound right...?

Anyone know where I can get my hands on half a dozen Raspberry Pi Compute Module 3+ units in the UK? They seem to be in short supply!

Someone made a Youtube video of about playing and modding a ZX Spectrum game I wrote 37 years ago when I was 16. I've written a bit about this fun reminder of my programming roots.

I've written about using Lambda@Edge with CloudFront to configure redirect rules for domains as a cheap way to keep URLs cool and avoid breaking the internet.

@IslandUsurper Thanks. I'm still relatively new to Nix and so while I'm learning I'm finding it useful to have the freedom to mess things up!

@IslandUsurper Vagrant is pretty irrelevant to what I'm trying to achieve. I'm just using it so I can try out the nix stuff out on a clean (Ubuntu) OS installation separate from my regular OS.

I now have multiple Rails apps each running in an isolated nix-shell with different versions of Ruby, Rails, PostgreSQL & MySQL...

@consoleaccess I've been really impressed with dnsimple so far, and although I haven't actually used their API in anger, it looks great!

More fun with nix. I've written about modifying the existing GitHub Action workflow that builds my personal website to use cachix/install-nix-action and nix-shell.

Hey folks,

The ruby.social domain name is up for renewal soon, and looking at the overall expenses of running this instance, we could _really_ use a few more supporters on Patreon to help cover costs.

If you can spare a couple of bucks, it'd be really helpful!

Super special thanks to the current patrons: @sidekiq @shanecav @passthejoe @MikeG1 and super-supporter @honeybadger :honeybadger:

:ruby: 🎉

I've been playing with the nix package manager, mainly with the intention of using it to setup isolated development environments. I've written up how I used nix-shell to define a Ruby environment for building & serving my personal website locally...
