WordPress 3.2, CentOS 5, PHP 5.2, & eAccelerator. What a mouthful.

Categories:

by

I wanted to update WordPress to 3.2 but hit a snag. Unfortunately 3.2 requires an update to PHP 5.2 which isn’t in stock CentOS. So I followed the instructions here to update to PHP 5.2 using the CentOS Testing repos. However I use eAccelerator which was built for 5.1 so before I could update the …

Building for older RHEL/Fedora releases on newer systems

Categories:

by

If you have ever tried to use a new Fedora or RHEL to build packages for older systems you may have run into errors at installation time. For example, if you were to roll a package on Fedora >=10 or RHEL >=6 and tried to install it on RHEL 5 you will get rpmlib(FileDigests) errors. …

Hmmm… you would think the empty set resulting from the intersection of the product title and product features would have been a clue that something was awry.

On topics such as how to run sudo from a cron job

Categories:

by

If you want to run sudo from any part of a cron job make sure you comment out the Defaults requiretty from /etc/sudoers. Bit me twice now so hopefully I’ll remember next time. Ed: Apologies to those who have read this before but I had to restore from backup and my last post wasn’t in …

Entourage Apple Script for Moving IMAP Mail

Categories:

by

In my last post I described a VB Script for moving IMAP email from my inbox to an archive folder. As an interesting Apples to Oranges (or Apple to Microsoft?) comparison here is the Apple Script I use with Entourage to perform the same task. I will post two versions: one that performs the exact …

Outlook VB macro for moving mail

Categories:

by

Been meaning to post this quickie for awhile. Took me a good bit of searching and tweaking but I’ve been using this macro for about two months to move email in my IMAP account in Outlook (2007) to my archive folder. Then I bound it to a hotkey combo by adding it to my menu …

Social Networking vs. Social Matrices

Categories:

by

In a social networking site that is truly extensible and robust we wouldn’t feel the urge to move on. Restarting on a shiny new site or culling or pruning your “friends” on an existing site wouldn’t be necessary. But we have been misled. Social networking doesn’t have to be all or nothing. We shouldn’t feel …

Solid State Devices (SSD) and journaling

Categories:

by

A few things all of us are probably interested in: SSD Write Amplification: http://www.extremetech.com/article2/0,2845,2329594,00.asp Journaling and write performance in ext4: http://thunk.org/tytso/blog/2009/03/01/ssds-journaling-and-noatimerelatime/ The bottom-line as far as wear and tear: vfat is basically the same as a journaled FS from a wear-leveling standpoint, both are worst case. Thankfully vfat, being the worst case, forced the manufacturers …

Disabling file access time updates using noatime in OS X

Categories:

by

The past few days people in Linux blogosphere have been bringing back up the noatime/nodiratime mount options. These options disable the updating of file and directory access times. On many standard systems when you read file a “last read,” or access time, timestamp is written to disk. Disabling the writing of access times can provide …
