Pro Drupal Development, Second Edition arrives
The author's copies of Pro Drupal Development, Second Edition arrived today. At 667 pages, the book is significantly thicker than the first edition!
I worked on this edition from November of 2007 to July 2008 pretty much without stopping. One morning my daughter found me in the living room writing a chapter at 3 am. It is difficult to express how much work this book has been, and how happy I am to hold the printed copy in my hands. Those who have written books will understand. :) I am glad to finally have it get into the hands of Drupal developers everywhere, and I hope that this contribution helps to complete the transition from Drupal 5 to Drupal 6. Thanks so much to all who have helped with this project!
Profits from the book go to this little guy's college fund. (And if you buy it through drupalbook.com, the Drupal Association gets a percentage of each sale.)
Installing APC on RHEL5
Here's how to install APC on RHEL5.
# yum install php-pear php-devel httpd-devel
# pecl install apc
# echo "extension=apc.so" > /etc/php.d/apc.ini
# service httpd restart
Check for the apc section in your phpinfo() page. If it's not there:
# tail /var/log/httpd/error_log
[Tue Aug 12 15:43:59 2008] [notice] Digest: done
PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib/php/modules/apc.so' - /usr/lib/php/modules/apc.so: cannot open shared object file: Permission denied in Unknown on line 0
SELinux is preventing the extension from loading, I'll bet. Let's check:
# tail /var/log/messages
Aug 12 15:42:40 mybox yum: Installed: httpd-devel - 2.2.3-11.el5_1.3.i386
Aug 12 15:44:01 mybox setroubleshoot: SELinux is preventing the httpd from using potentially mislabeled files (./apc.so). For complete SELinux messages. run sealert -l 9e4bbfa8-327b-4bb2-94df-f154045a1ef1
Let's view the security contexts for our PHP extensions:
# ls -Z /usr/lib/php/modules
-rwxr-xr-x root root root:object_r:tmp_t apc.so
-rwxr-xr-x root root system_u:object_r:textrel_shlib_t dbase.so
-rwxr-xr-x root root system_u:object_r:textrel_shlib_t gd.so
...
Yup. Notice how the security context is missing (it's tmp_t for apc.so). Let's fix that.
# restorecon /usr/lib/php/modules/apc.so
]# ls -Z /usr/lib/php/modules
-rwxr-xr-x root root system_u:object_r:textrel_shlib_t apc.so
-rwxr-xr-x root root system_u:object_r:textrel_shlib_t dbase.so
Joining Lullabot
The rumors are true! As of today, I'm officially a Lullabot. People have been asking me, why leave the safety of a solid academic position to join a small company? I think the better question is, what kind of a company must Lullabot be for someone in a solid academic position to leave academia in order to join it? For those just stirring from in front of their VAX terminals (and why should they? the system is still up!), Lullabot is an open source education and consulting firm, focusing on the increasingly popular content management framework Drupal.
I look forward to being more involved in the open source community. And yes, the book is almost done!
Go ahead and ignore
Hmm, I think I will go ahead and click Ignore...
Second edition progress
I thought I'd update everyone on the progress of the second edition of Pro Drupal Development.
The second edition will cover Drupal 6, and is expanded to cover new core topics like actions, triggers, AHAH, etc.
Workflow 5.x-2.0 released
I've finally got a project that uses the workflow module so I've been able to justify putting some time into it. As a result, I've released version 5.x-2.0. This version of workflow works with the 5.x-2.x version of actions, which is the backport of Drupal-6-style actions to Drupal 5.
Growth of Drupal
Others are posting on Drupal's growth today. A picture is worth a thousand words, so here are 2000 words on the subject:
Letter to Dries, July 2004
At Drupalcon 2008, one question I was asked a number of times was "how did you get involved with Drupal?" Here's one of my first letters to Dries, after discovering Drupal in 2004. Interesting to think about how far we've come since then.
Hi Dries,
Slides from Drupalcon Boston 2008
Video of the presentation I gave at Drupalcon Boston 2008, titled Triggers and Actions and Hooks, Oh, My! should be appearing shortly. (In the meantime, here's me babbling about actions.) The slides are downloadable below.
XServe RAID discontinued
Apple has discontinued their confusingly named XServe RAID storage system. That's a shame, and yet another red flag for trusting Apple in the enterprise market, in my opinion.
I currently administer two of these (one on OS X Server and one on RHEL5), and I can't say enough good things about them. They have been reliable and fast. When a disk goes out, the system sends out notification and starts a rebuild on the hot spare automatically, just like a good RAID should. And they're quieter than any other dedicated RAID solution I've looked at. RIP, XServe RAID.
