comment Convert thousands of .pngs to animated .gif, `convert` uses too much memory
Another consideration is the memory requirements for the resulting GIF: I would expect it to require N x width x height x number of frames (where N is either 1 or 4, more likely 4), so, again, a 1024x768x1000 frames GIF would likely require ~3Gb of RAM to display. The actual filesize would be much less of course.

Re. "where all the memory is going": 65 Kb is the file size of a compressed image. When uncompressed, the image takes roughly 4 x width x height bytes, so a 1024x768 image would take ~3Mb of RAM. Multiply that by "a few thousand" and you'll see where the memory is going...

comment Difference between “su”, “sudo -s”, “sudo -i”
@Whaaaaaat: well, it's similar, although I'm not sure if there are any differences related to login shell, environment etc.

comment Does using -v (verbose) slow commands down?
The most impact, and probably the only case where it would really matter, is when you run the command on a remote machine via SSH. Verbose logging may easily generate tens of megabytes of traffic which would have to be transmitted from the host to your console. I once experienced a speedup in order of 10x after removing excessive console logging from a script which I ran via SSH.

comment Install CDE on Ubuntu
Are you sure you're talking about CDE (a desktop environment developed in 1990th and not widely used anymore) and not KDE? Your user avatar looks like a default background of one of previous versions of KDE.
