      "Windows 95 was 30 MB" is such an ignorant, obnoxious, trite take. a triple buffered framebuffer (which you want for smooth scrolling) for my 4K display is 70 MB in *pixels alone*. Obviously a complete webpage with precomposed textures would take more.https://twitter.com/julienPauli/status/1042113172143067138 …

      this article says "Linux kills random processes by design. And yet it’s the most popular server-side OS." which i assume is talking about the OOM-killer but makes me imagine, like, linux just randomly killing processes for no reason

      you can just turn off overcommit if you want. actually understanding that doesn't make for a good rant though

      Replying to @whitequark @hierarchon

      yeah, but then fork stops to work, and there’re lots of things depending of fork. Actually understanding “there’s an option but nobody uses it” doesn’t make for a good argument though

      So you are simply assuming *he* (implying *everyone* using linux kernel) can turn it off because it works for *you*. Are you suggesting this mechanism is actually not needed in the kernel as everyone should have it turned off?

      Replying to @OndrejPinka @nikitonsky @hierarchon

      nope. he claimed that setting vm.overcommit_memory=2 inherently breaks fork, which is obviously false, as anyone can verify by, for example, doing that on one of their machines and observing the results

      Replying to @whitequark @OndrejPinka @hierarchon

      so there’s no problems with fork and vm.overcommit_memory=2? Why isn’t it the default or even recommended setting then?

      Replying to @nikitonsky @OndrejPinka @hierarchon

      there are obviously no problems with fork and without overcommit because Linux is the only Unix-like that has overcommit enabled by default in the first place, yes.

      i guess it's too much sarcasm to me. I have no idea what are you trying to say anymore

      no sarcasm. I'm saying that you can just disable overcommit and have Linux work like every other OS with fork()...
