Every year we count the remaining days. And every year, it’s worth it. This is our 2010 System Administrator Appreciation Day gift! In 2009 we had pretty cakes as well! And if you need a reminder for why we deserve this day, have a look here.
I love being in IT. :-)
If you haven’t heard of it yet, there’s a very intersting tool available called phpsh, a python implementation to a PHP shell – but better.
Installing phpsh
SSH into your server, and download, build & install the binaries. This assumes you’ve downloaded the .tar.gz version.
# wget http://github.com/facebook/phpsh/tarball/master
# tar xzf facebook-phpsh-1bc1c01.tar.gz
# cd facebook-phpsh-1bc1c01/
# python setup.py build
# python setup.py install
# phpsh
As simple as that.
How do I use it?
Even more simple. Once the install is done, execute phpsh on the CLI, and get started writing PHP code.
srv ~ # phpsh
Starting php
type ‘h’ or ‘help’ to see instructions & features
php>
php>
php> echo “Testing this new PHPSH”;
Testing this new PHPSH
php>
php>
php> $dbconn = mysql_connect(‘localhost’, ‘user’, ‘pass’);
PHP Warning: mysql_connect(): Access denied for user ‘user’@'localhost’ (using password: YES) in /usr/lib/python2.4/site-packages/phpsh/phpsh.php(534) : eval()’d code on line 1
php>
php>
php> exit;
This can help to easily test or debug some PHP code. It has syntax highlighting, tab completion (!!), manual pages, … Still not convinced? Have a look at some real-life examples for a PHP interface shell. Seriously, awesome tool.
I won’t be going into detail what DNSSEC is, and what it does. This only covers the implementation (deployment) and maintenance that accompanies DNSSEC. Here’s the small index of topics I’ll cover.
There are a few assumptions throughout this article, mostly related to directory structures as I like to keep things organized. Another method would be to create a directory per zone, and store all data within that directory.
Since I’ve not updated this blog in quite a while, I’ll share a very interesting video and mention its highlights.

Obviously, Facebook has seen amongst the most impressive scalability problems ever. And here are some of the interesting bits, which can be used to manage and tune high traffic & high availability websites.

Not tech-related, at all. But since I can use the extra promotion in selling it …
For sale: Classic Mini, British Open (Special Edition). This version was created in limited stock. Only 1.000 in the UK, and 2.000 more in Europe.
It features an electric sunroof, 1.3l petrol engine, and the driving experience of a lifetime. It’s on sale since I lack the time to fully enjoy it. It’s among the best preserved British Open’s I’ve ever seen, fully restored by it’s previous owner.
It’s located on several dealer-sites:
And if you’re up for some mild reading, I would recommend: The History of Mini. Some more info on the car can be found here.
