The latest version of boot2docker 0.8.0 comes with docker 0.10.0 but we get some strange errors. So if you want to have multiple boot2docker/docker versions parallel you can use this process

boot2docker settings

Boot2docker has 3 parts:

• boot2docker vm: a VirtualBox vm which is a customized TinyCoreLinux image a bare minimum linux which has docker already installed in it.
• boot2docker.iso: the boot2docker disk image
• a shell script: which helps to create/manage the VirtualBox which uses the boot2docker.iso

The apibunny challenge

There is a geek challenge called apibunny to play with rest apis.

my 1-liner (140 chars) script which fits in a twitter message:

c(){ curl -O http://apibunny.com/cells/$1;for  l in $(sed -n "s/.*\([[:alnum:]]\{16\}\).*/\1/p" $1); do wc $l || c $l;done; } && c taTKQ3Kn4KNnmwVI
