Fix Fedora Deep Sleep

My deep sleep was not working when I closed the lid of my laptop since Fedora 40. It was caused by the mem_sleep mode set to s2idle instead of deep, no idea what changed it, but here’s the solution.

Check if the current mode is s2idle:

$ cat /sys/power/mem_sleep
[s2idle] deep

To change that to deep:

$ sudo sh -c 'echo deep > /sys/power/mem_sleep'

It should now be fixed:

$ cat /sys/power/mem_sleep
s2idle [deep]

Also, add the following to /etc/default/grub:

GRUB_CMDLINE_LINUX_DEFAULT="mem_sleep_default=deep"

And update grub (you might need to adjust this command to your system):

$ sudo grub2-mkconfig -o /boot/grub2/grub.cfg

How to write Go HTTP service

A guide on how to write HTTP service using Go coming from someone with 13 years of experience. I think it’s a good one, even though I don’t really agree with some points, but that’s probably because I never encountered the issue that they had.
