bash saved my day

less than 1 minute read

I was creating an ugly quick-and-dirty script to setup the squid cache_dir automatically with puppet based on the diskspace and memory available.

When you are developing you sometimes forget to create backups and push it to git, and mistakes are around the corner.

Lucky bash saved my day!

$ ./create_cache_entries.sh  > create_cache_entries.sh 
-bash: ./create_cache_entries.sh: /bin/bash: bad interpreter: Text file busy
$ vi create_cache_entries.sh

yum update on fedora 19 and zfs on linux

zfs

I use zfs on linux on fedora now.

The installation was pretty straightforward but after the installation of zfs yum update failed.

Running kindle on GNU/Linux with wine

less than 1 minute read

desktop

I enjoy reading ebooks during my train trip to work on my nexus 7.

At home I prefer to read on my monitor since this is bigger.

Most of the time I use epub or pdf for reading, I bought a kindle version of a book from amazon assuming that I could read with amazon cloud reader at home.

Unfortunately this books is not compatible with cloud reader.

Proprietary_formats should be avoid, lesson learned (again).

To read my book at home I decided to give the windows version of kindle on wine a try

The installation was pretty straightforward on Fedora 19.

  • Install wine
[root@vicky ~]# yum install wine
Loaded plugins: langpacks, refresh-packagekit

  • Download Kindle for Window xp

Download it from: http://www.amazon.com/gp/feature.html/ref=kcp_pc_ln_ar?docId=1000426311

  • Run the installer
[swagemakers@vicky ~]$ wine ~/Downloads/KindleForPC-installer.exe 
  • Create kindle startup script
wine $HOME/.wine/drive_c/Program\ Files\ \(x86\)/Amazon/Kindle/Kindle.exe &

Happy reading

but
