Dropbox Command Line

Feb. 28, 2012, 1:46 p.m. Centos , cloud , dropbox , perl

There are many command line clients for dropbox, but one that I liked as soon as I saw it was the rather boringly name dropbox-api-command (I suppose all the good names had been taken). Installation is easy but if you are on Fedora or CentOS, the first line in the installation instructions will not ...

Percona Installation Woes

Nov. 12, 2011, 1:29 p.m. AWS , Centos , cloud , mysql , Percona , REMI , Webtatic

It turns out that all the EC2 Amazon Machine Instances that have Percona installed by default have older versions of either Percona or PHP or both. My intention was to use Percona on a web app so it's required that the version of PHP is reasonably new.  So the logical thing to do is to install Perco ...

After suffering three site outages in as many days, I decided to wring in a few changes. One of them being adapting Cloudflare.

Encrypted filesystem on linux

June 10, 2010, 1 p.m. Centos , fuse , security , steganography , virtualization

Six years ago, I had a post with this exact same title. At the time it was about making a crypto loop. Cryptoloop allows you to create a large file, ecrypt it and then mount it with the help of a loop back device as a file system. The contents cannot be seen without the proper password. Truecrypt is ...

Centos 5.4 , PHP 5.3 and Harvard Referencing.

March 1, 2010, 11:45 a.m. Centos , cloud , deadinedue , virtualization

A couple of days back, we did an update to Deadlinedue, the Harvard reference generator, the moment the database was updated and the new code was put in place, PHP started segfaulting. It was time to decide whether to roll back or press forward. I chose the latter and it resulted in the site been of ...
