Notes

I have used Arch, Getoo, and Qubes as my old operating systems, and some of them have suddenly developed OS problems at one point and could not boot. So I have several unused laptops in my room that are junk. The phone I use is a Google Pixel, which is the least bak and most stable. I used to install custom roms and play with them. For now I have landed on GrapheneOS. I was playing around with various routers NEC Univerge IX for internet connectivity. The browser I use most often is Chromium, which is the fastest browser I use (although it uses a lot of memory...). Other applications I use

• Futo Voice : I can use voice input offline.
• Shelter : I can duplicate one app in my work profile, so it's really useful.
