Tip of the Day: have your mac command prompt tell you which git branch you're in

A colleague just shared this tip with me to have my Mac command prompt tell me which git branch I'm in:  Put the following in your .bash_profile

 

function parse_git_branch () {

  git branch --no-color 2> /dev/null | sed -e '/^[^*]/d' -e 's/* \(.*\)/ (\1)/'

}

 

export PS1="\h:\W \u\$(parse_git_branch)\$ "

Now my command prompt looks like this in a git directory:  belldev2:docroot barnettech (master)$

Too many connections error

If you're getting a too many connections error on your Drupal site and the site is down -- likely once a day.  Never fear, here is the answer ... this blog just suffered through that, and just upgrading Drupal to the newest version -- all modules as well, solved the problem.  Yes i don't get paid to write this blog and it suffered some down time, as it doesn't bill as top priority, so sorry for that folks.  Anyhow, might I suggest you use drush to keep your Drupal install up to date.

Run:  drush @your_alias_name up  

What to do if your Drupal site gets attacked by spammers and Black Hat SEO

So your site is being attacked with lots of spam user registrations and comments, and even nodes, what should you do.

1.)  Install the Mollom module

   -- configure mollum by going to the mollum website http://mollom.com/ and get your free api keys.  You can get a paid account for larger corporate sites.

VIM tip of the day

to delete or yank (copy) a whole function try this:

If you're on a parentheis, or curly bracket or even a quote sign you can always hit the % sign to go to the closing parentheis, curly bracket or quote sign in vim.  So you can instead do "d%" to delete all in between said quotes, curly brackets, or parenthis or you can do "y%" to yank the lines (copy) and then later go to where you want to paste those yanked lines and hit the "p" key.

Yes finally.  Great for when you're refactoring your code and moving functions around.

Basic Linux Hardware analysis Notes:

How many php procs are running:  ps -A | grep php-cgi | grep -v grep | wc -l

 

A box with a 1 minute load average of 6.92 should have been below 2 if it had a 2 cpu core.

 

To find how many cpu cores there are:

cat /proc/cpuinfo  (or just type cat /proc/cpuinfo| grep processor| wc -l to get how many cpus)

4 processor core would look like

processor : 0

vendor_id : GenuineIntel

<---SNIP--->

processor : 1

vendor_id : GenuineIntel

<---SNIP--->

processor : 2

vendor_id : GenuineIntel

Make Drupal's l( function just be a false link for javascript pointing to the # (hash) sign

Make Drupal's l( function just be a false link for javascript pointing to the # (hash) sign

This works and is in production for us:

l(t('Start Chat'), '', array('attributes' =>
        array('title' => array('Start Chat with ' . $row2->full_name)),
          'fragment' => ' ', 'external' => TRUE)) 

Using Kcachegrind to profile your code

1.)  Install xdebug -- I'm running MAMP so it's already installed and in php.ini I just needed to turn it on here are my settings:

[xdebug]

zend_extension="/Applications/MAMP/bin/php/php5.3.6/lib/php/extensions/no-debug-non-zts-20090626/xdebug.so"

;xdebug.profiler_output_dir = "/tmp/xdebug/"

;xdebug.profiler_enable = On

xdebug.remote_enable=On

xdebug.remote_host="belldev"

xdebug.remote_port=9000

;xdebug.remote_handler="dbgp"

;xdebug.idekey=ECLIPSE_DBGP

;xdebug.remote_mode=jit

Droogle for Drupal 7 Released Integrating Google Drive and Drupal

Droogle for Drupal 7 was just released and supports Google Drive features and folder level support. http://drupal.org/project/Droogle Droogle is a project I've authored that is sponsored by Babson College, and integrates Google Drive (formerly Google Docs) with Drupal. There is now both a Drupal 6 and a Drupal 7 version available. Folders are now displayed -- out of the box the css supports up to 5 levels of folders, the php supports infinite levels, and the css could easily extend to support more levels.

JABBER module for drupal is now released

Jabber integrates Drupal with XMPP (jabber) chat. The module enables it so any username anywhere on the site will turn green, grey or red reflecting their jabber status. The module integrates your roster with Organic Groups, and your regular instant messenger roster list. The module preserves chats, and chat history between your drupal page loads. The readme is below.
