This is a simple tool for displaying memory information including compression ratio and percentage of compressed memory in Linux kernel using zram. This tool works without zram, but in that case it displays only basic memory statistics.
With LC_NUMERIC=en_GB.utf8 the output of ./zraminfo looks like this:

| # Unwraps Flash Video container and removes video (if any) from given file and outputs .mp4 file which may be | |
| # played back with almost any device you own. No re-encoding is performed so the quality stays the same as in | |
| # original. | |
| # | |
| # Suggested use with yle-dl, Youtube downloader, etc. | |
| ffmpeg -i "$1" -vn -acodec copy "`basename "$1" .flv`.mp4" |
| #!/bin/sh -eu | |

FizzBuzz written in POSIX shell by Joel Lehtonen ([email protected])
This is an entry to evergoing FizzBuzz challenge of Linkki Jyväskylä ry. Used techniques include Emacs, Inkscape, Gimp, and a pixel conversion tool I wrote in Haskell.

| * Console tick clock by Joel Lehtonen, joel.lehtonen ät iki.fi | |

| * Clock which outputs a character every second. The time displayed | |
| * matches the wall clock at every newline. | |
| * | |
| * This may experience leap second issue. Not tested with that. Also, | |
| * sorry about the magic numbers. This is just a funny console clock, | |
| * not a proof of work :-) |
