What got me stumped recently:

  • Just couldn't figure out how to solve things just by scans in Theano metaprogramming language too)
  • Doesn't have the foresight to determine whether C++ template metaprogramming is worth the time invested in learning it.

...just for the heck of it? Or is it for system forensics?

comment How to completely disable swap?
Okay so can I disable paging instead? Like psusi said, on usual usage, my ram only maxes out due to runaway process. Even if enable swap, the runaway process will manage to fill all of swap and still make the computer unusable in the end (it happens when I don't carefully monitor what's going on in the web browser's background)

comment How to completely disable swap?
There's something about how Linux handles virtual memory that I don't understand. I've disabled swap in most ways possible: via swapoff, and via vm.swappiness=0. Yet kswapd0 still runs! I wonder if this is a regression from the 2.4 days…

I don't have swap in init.d, nor do I have it on fstab, but I do have /etc/init.d/mountoverflowtmp that mounts tmpfs for emergency log writes. Does the swap daemon use tmpfs too?

@Mat hmm, then it was permanent probably due to deletion of that line in fstab. My mistake!

@enzotib I have no swap in my fstab.

@Mat swapoff -a should disable swap permanently, meaning it should stay disabled after next reboot. I confirmed this. Yet, I/O "storm" still happens during the session after next reboot. For the record, I/O "storm" didn't happen at the moment I did swapoff -a because swap was 0 at that time.

comment Install ffmpeg 0.7.1-5 from debian package
You have to install the new dependencies. As they are not on Ubuntu's repo, you can either: (a) add Debian Wheezy's repo, or (b) download all the dependencies and dpkg -i all of them in the same line.

comment Apt/Aptitude: how to filter packages that are impossible to install?
I can't find any one package that lists such tool. Many packages related to deb, but little about dpkg.

The last time I tried it worked, but was very slow. Try reading this: debtorrent.alioth.debian.org/Install

comment Aptitude: What is the filter for virtual packages that has been provided?
Thanks! I've tried so many combinations, even using to ?for but still couldn't figure out why they don't work. Then I realized ?for doesn't return a different package; it only applies filter with the condition given.
