Interesting new packages

A lot of new packages got imported, some are alternatives of packages already available, but many are bringing possibilities we didn't have before.

7.1-stable updates (since last webzine issue)

Shell tips

To improve performance or reduce disk i/o for some workload, you can mount /tmp in memory using mount_mfs. When doing so, the new fstab entry would look like this:

swap /tmp mfs rw,nodev,nosuid,-s=800MB 0 0

In this example, we used 800MB, you should adapt according to how much memory you want for /tmp.

You can find your memory size using dmesg and awk:

dmesg | awk '/avail mem/'

Here is a command generating a fstab entry assigning 10% of your memory to /tmp/, you can use it in place of your /tmp/ entry: 

printf "swap /tmp mfs rw,nodev,nosuid,-s=%sB 0 0\n" \
$(dmesg |awk '/avail mem/ { print int($4 /10) }')

You need to adjust /tmp permissions:

 # chmod 1777 /tmp

Note from the editorial team

Note from Solene

This issue is late again. It's hard to find a good publication rate fitting with this hobby work. Originally, I planned to publish every two weeks, that would allow me to gently gather links and material for a new zine, but at the same time there are periods like before a new release during which nothing happen. On the other hand, when waiting long between publications without having a clear deadline, a lot of content need to be covered and it accumulates in a huge pile, which is not necessarily fun to go through. However, while the Webzine is late on schedule, it reached EIGHT different languages; not all the issues got translated into the eight languages but it's been very comforting to meet all the people working on the translations, THANKS!
