Hi,

If you go to Paris, here are some places I like. I tried to group them by area. Of course there are MANY places in Paris; but I listed those I like to visit when I go back to Paris.

Saint Michel

The "Saint Michel" area is just South of "Notre Dame" (the huge church on the small island in the middle of Paris). There is the famous "Saint Michel Fountain",

Mouses Are Overrated

This script allows you to enable/disable your pointers on a Linux machine.

Usage:

mao.sh on   # enters "mouseless" mode
mao.sh off  # returns to "I can has clicks" mode

Note: if you just want to disable built-in pointers (to keep a mouse on the side

1. Start container
2. Create view.sh
3. Create a FIFO with mkfifo /tmp/view
4. Have a writer on the FIFO: just leave cat >/tmp/view running somewhere
5. Run socat TCP-LISTEN:8080,reuseaddr,fork EXEC:/path/to/view.sh
6. Whenever you want to kick everybody out, you can kill socat or kill the cat process :-)

Base 27 encoding

This is just for lulz.

• Take a character string (ASCII8, no character >242).
• Transform each byte into a sequence of 5 trinary digits (i.e. from 00000 to 22222).
• Concatenate all trinary digits (i.e. a long sequence of 0, 1, and 2).
• Add extra 0s at the end so that the total length is divisible by 3.
• Break down by groups of 3.
• Transform each group of 3 into an integer, ranging from 0 to 26.

Get little rootfs from https://github.com/jpetazzo/docker-busybox/blob/master/tarmaker-buildroot/rootfs.tar

mkdir c1 c2
sudo tar -C c1 -xf rootfs.tar
sudo tar -C c2 -xf rootfs.tar

Now we will prepare c1 to host a shared mount with c2:
