How to use channels across different processes in Go

A couple of code samples to show how a named pipe can be used to extend Go's channel paradigm for use between different processes running on a system.

• interprocess1.go details a single byte channel.
• interprocess2.go details a channel that passes slices of bytes.

Note that opening a write channel will return two channels -

Automating Daily Reports, because fuck it, really...

Each day at our company, developers are required to document their activities, painstakingly jotting down their daily work and future plans. A monotonous chore that I just really dislike.

A way to install Alpine Linux on a Scaleway Stardust instance without the use of a rescue image, but by booting into the install image over the network using https://netboot.xyz.

1. Connect to the serial console, using scw instance server console {uuid} zone={zone}

2. Reboot the VM into UEFI settings

   • either by executing systemctl reboot --firmware on the machine
   • or by using scw instance server reboot {uuid} zone={zone} locally and repeatedly mashing the escape key on the serial console

3. Go to Device Manager -> Network Device List -> the only network device -> HTTP Boot Configuration -> Boot URI
