Example below stems from my adventure starting with C#/.NET by fixing some issues in CycloneDX tooling. One big caveat was getting my custom-built library used by the custom-built tool (and VS Code IDE to debug). Ended up with the following; maybe better ways exist...

• Install DotNet and NuGet
  • TODO: How did I get that on Windows?
  • Ubuntu Linux (in WSL):

:; sudo apt-get update && sudo apt-get install dotnet7 nuget

CONTEXT

TL;DR: See about installing MUSL tool-chain, and scroll down to exfatprogs build - that's what did work best for me.

Needed fsck.exfat 1.3.0 or newer to actively fix SD card issues on an Android phone. All builds I could find were older, so can only detect problems but not fix them even though these versions are supposed to be able to fix "some corruptions" (assuming exfat-fuse 1.3.0 here), e.g.:

:; which fsck.exfat
/system/bin/fsck.exfat

How to GPG as a Scala OSS Maintainer

tl;dr Generate a GPG key pair (exercising appropriate paranoia). Send it to key servers. Create a Keybase account with the public part of that key. Use your keypair to sign git tags and SBT artifacts.

GPG is probably one of the least understood day-to-day pieces of software in the modern developer's toolshed. It's certainly the least understood of the important pieces of software (literally no one cares that you can't remember grep's regex variant), and this is a testament to the mightily terrible user interface it exposes to its otherwise extremely simple functionality. It's almost like cryptographers think that part of the security comes from the fact that bad guys can't figure it out any more than the good guys can.

Anyway, GPG is important for open source in particular because of one specific feature of public/private key cryptography: signing. Any published software should be signed by the developer (or company) who published it. Ideally, consu

= Self-wrapping code()

I have my own version of "declarative" we use, and in that case you can add parameters like timestamps: true so I have code roughly (see below) like:

def workflow = { // stuff to do }
if (config.timestamps){
    //*******NEEDED *****//
    def inner = workflow()
    //********************//
 workflow = { timestamps { inner() } }
