access Linux from Windows: SSH terminal, files, web
I've been using Ubuntu as the operating system (OS) for my main computer for years, but recently still gave my old Windows machine another chance.

When Ubuntu stops responding: Linux Memory Leak
After my Linux computer did not respond again and again, I was looking for the cause. The file manager Dolphin, for example, always manages to consume the entire memory, which then brings the computer into an unusable state. Although not a solution, but a way to stabilize the computer, provides the package earlyoom. Earlyoom controls the memory and terminates certain processes if necessary.
