Too many connections error

Submitted by barnettech on Thu, 02/21/2013 - 10:30

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

VIM tip of the day

Submitted by barnettech on Mon, 01/28/2013 - 15:31

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


processor : 1

vendor_id : GenuineIntel


processor : 2

vendor_id : GenuineIntel

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

          'fragment' => ' ', 'external' => TRUE))

Submitted by barnettech on Wed, 05/30/2012 - 15:14

Droogle for Drupal 7 was just released and supports Google Drive features and folder level support. 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.

Submitted by barnettech on Tue, 05/29/2012 - 11:07

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.

These directions are no longer current but support the versions of Droogle prior to version 7.x-4x.

Make sure to see the readme file in the Droogle files folder but here are some tips: To configure what file types Droogle file upload will accept: Annoyingly I agree you have to edit Droogle/Zend/Gdata/Docs.php and add the filetypes that are allowed for upload. Here is my current list.
