Are You Reading Too Much?

Reading, after a certain age, diverts the mind too much from its creative pursuits. Any man who reads too much and uses his own brain too little falls into lazy habits of thinking.

The theming firehose (NB for designers & front-end developers new to Drupal) | rare pattern

October 12th, 2011 Abhimanyu Gupta
{ Comments }

You theme with the mark-up you have, not the mark-up you'd like to have.

That's the essential truth that designers and front-end developers new to Drupal need to understand. You don't get to construct your pages from scratch, building out essentials, never a wasted div, never an extraneous class. No, you have to flip the entire process around. With Drupal you're getting markup shot at you from a firehose, and as a themer you need to sop it all up and make it pretty. Don't spill a drop.

How to downgrade PHP to 5.2 on Ubuntu?

July 29th, 2010 Abhimanyu Gupta
{ Comments }

Here is a quick script to do this task:

Courtsey of Stijn Beauprez from here: http://thejibe.com/blog/10/5/php-5210-debs-ubuntu-104-lucid#comment-9

#! /bin/sh
php_packages=`dpkg -l | grep php | awk ‘{print $2}’`

sudo apt-get remove $php_packages

sed s/lucid/karmic/g /etc/apt/sources.list | sudo tee /etc/apt/sources.list.d/karmic.list

sudo mkdir -p /etc/apt/preferences.d/

for package in $php_packages;
do echo “Package: $package
Pin: release a=karmic
Pin-Priority: 991
” | sudo tee -a /etc/apt/preferences.d/php
done

sudo apt-get update

sudo apt-get install $php_packages

To undo the script and upgrade to php 5.3 you will need to delete the file (sudo rm /etc/apt/preferences.d/php), run sudo apt-get update, and then sudo apt-get dist-upgrade which will get the latest packages for your distribution, including the PHP packages. (Ben Holt)

How to auto start services on boot in Centos / Redhat?

June 1st, 2010 Abhimanyu Gupta
{ Comments }

To auto start services in Centos or Redhat OS, you can use builtin chkconfig utility. It is located in /sbin directory. If you are a regular user (non-root), then /sbin may not be in your path. Therefore, you may have to use the full path to access the chkconfig utility.

To auto start a new service:

  • Find out the name of service’s script from /etc/init.d/ directory e.g. mysqld or httpd
  • Add it to chkconfig
    sudo /sbin/chkconfig --add mysqld
  • Make sure it is in the chkconfig.
    sudo /sbin/chkconfig --list mysqld
  • Set it to autostart
    sudo /sbin/chkconfig mysqld on

To stop a service from auto starting on boot

  • sudo /sbin/chkconfig mysqld off
