I still prefer to run everything built directly from reliable deb sources.

As an end user... sure, flatpaks and appimages and snaps are I guess neat if you are constantly distro hopping or something, at least in theory.

But uh, I have already found the ability to play games, develop games and other software, use basic daily software for everyday needs, and have a stable and predictable OS that doesnt crash or have insane misconfigurations caused by some esoteric conflict by just basing everything directly off of deb sources.

Every once in a while I will have to compile my own build, but this is rare and usually only occurs when trying out something experimental, or, also rare, something that doesnt have an actively and well maintained deb source. In that case its just a matter of doing a build from github when a new version comes out.

And I can do builds from github because I have saved a lot of storage space from not using bundled installers for all my software, allowing me to store the sources. This is also neat because it allows me to quickly /use/ one of those sources in a project, after I have already seen that it is stable via the software I use that is built on it.

Finally there is the security angle. Using a myriad of different containerized installers for everything is convenient in that you don't have to directly worry about source management... until you do, when a source lib is discovered to have a critical flaw.

When a serious flaw is found in a source library... what's gonna get updated faster? A containerized installer that you have to wait for the devs, who are busy managing tons of cross platform dependency issues and have to do a new safe stable build everytime any of their many dependencies for their many supported platforms? Or an app specifically built from source libs that either doesnt focus on cross platform, or has different teams specific to maintaining its different supported flavors?

In my experience, literally all of the time, the 'direct from source' software gets updated more quickly than the cross platform bundled installer.

Further, this whole approach here gives you experience with software that is built on source packages that, as you become more familiar with, and tinker with yourself, gives you insight into what source libs are well coded in terms of cpu/gpu/ram optimization, and which are resource hogs and should be avoided if youre interested in promoting and using software built off of efficient code. I enjoy learning from the good coding techniques of stable, lean and fast programs, and avoiding code that is comparatively unstable, boated, or slow.
