If you use Git for version controlling some projects of yours and you are a number-crunch fanboy, you might be interested to know which hours you (or some fellows in your team) are active the most. I mean which hours during the day you do your commits. This is onliner will do this for you. Run it from inside your project dir:

VirtualBox is a great piece of virtualization software. It not only allows us to run and test different Operating Systems inside Virtual Machines (VMs) from the comfort of our main desktop computer with point-and-click, but it also enables us to setup and run VMs on remote headless servers from the command line. And we can control these VMs remotely via a plain RDP client. This is great because when you host your VMs on server hardware (usually without any graphical UI) you don’t really need the full fledged GUI of VirtualBox (and its Qt/SDL dependencies) nor to display the VM output locally. Instead you just need some commands to setup and start your VM. Then all you want is to connect to it remotely and install an OS. With VirtualBox, this is accomplished via the commands VBoxManage and VBoxHeadless. This is how it can be done.
What is Varnish?
Varnish Cache or just Varnish is an open-source HTTP accelerator and caching reverse proxy for web servers, like Apache or nginx, hosting content-heavy dynamic web sites. In non-geek speak, Varnish is an free program which runs in front of your web server (which in this context is called backend or origin) and stores (caches) a copy of each webpage served by the web server. When a user requests a cached page, Varnish steps in and serves the cached copy instead of requesting the same page again and again from the backend server. So Varnish is ideal for developers who run high traffic sites with lots of visitors and like their web application to be highly available and running fast. This how-to is an attempt to present a comprehensive but simple introductory guide to Varnish configuration for web developers who want to scale their projects gracefully.
Τι συμβαίνει όταν η linuxάδικη ομάδα ενός επιτυχημένου ειδησεογραφικού site συνεργάζεται με γνωστούς και πετυχημένους αθλητικούς δημοσιογράφους; Μπορεί να γεννηθεί ένα νέο, μοντέρνο και ανεξάρτητο αθλητικό site: το coppa.gr.
Στημένο σε Drupal, το coppa.gr είναι “100% powered by Linux” και ανοικτό κώδικα: από τα desktops των συντακτών που τρέχουν Kubuntu και το pfSense firewall μέχρι τον Debian server με Apache, MySQL κλπ. Εντυπωσιακό, νομίζω, γρήγορο και καλαίσθητο, το COPPA φιλοδοξεί να μεταδίδει καθημερινά, έγκαιρα και έγκυρα, αθλητικα νέα από όλα τα σπορ, χωρίς κασκόλ και εξαρτήσεις. Άλλωστε, το περιεχόμενο «υπογράφουν» άνθρωποι που γνωρίζουν το αντικείμενο καλύτερα από τον καθένα: Σωτηρακόπουλος, Σπυρόπουλος, Βέργης, Θειακός, Σωτηρίου, Χριστοφοράκης, Λοθάνο, Τσούτσος, Θαναηλάκης κα.
Τεχνικά, η υλοποίηση έγινε με D7, Zen, megamenu, views, rules, media, ckeditor και τα υπόλοιπα γνωστά modules της κοινότητας του Drupal, την οποία χιλιοευχαριστούμε.
Χαρείτε το!

After years wasting time on drupal/sql backups, drupal restores, drupal updates etc, I started using the powerful drush command.
If you don’t know it “drush” is simply a (dru)pal (sh)ell written in PHP. It has been developed by core drupal developers to assist sysadmin and developers in everyday site management.
First, to install drush in a typical Debian/Ubuntu server, you need to install the PHP Extension and Application Repository (PEAR) which hosts drush. Simply type:
Just use the fabulous command REPLACE provided by mysql. The syntax goes like this:
update database_table set table_column = replace (table_column, "oldstring", "newstring");
For instance, to replace all occurrences of “modules” inside the linuxformat.gr drupal db with “sites/all/modules” I typed in:
update linuxformat_system set filename = replace (filename, "modules", "sites/all/modules");
