2014-05-09: PHP: Why might session_start fail, claiming "no such file or directory"?

Posted at 2014-05-09 15:49:30 by SHD

Here's a little problem that bit me after an OS upgrade to a webserver. Whenever session_start was called, PHP would throw a warning message and not actually start the session:

2013-05-23: Tip: Getting rid of the warning "The column name 'start' is a MySQL reserved keyword."

Posted at 2013-05-23 15:20:39 by SHD

Version 4 and later of popular database management tool phpMyAdmin "helpfully" displays warnings when a column name in a database conflicts with a reserved word in MySQL. This may or may not be an actual problem. If you are in the habit of enclosing table names in your SQL queries in `backticks`, it shouldn't be a problem at all. For others, it may depend on the actual column name. In the example provided below, "start" and "end" can safely be SELECTed unquoted, whereas "group" needs the backticks. At any rate, having the warnings show up the whole time rather than just at table creation time is annoying. Here's how to disable them.

2012-11-24: Browser tip: Keep video full screen with multiple monitors (Firefox)

This makes it completely useless for watching video while doing something else. There is a fix for it.

2012-01-17: Browser tip: Quickly remove old autocomplete entries

Here's a quick tip. If you're entering information into a web form and have outdated or incorrect suggestions in the autocomplete dropdown that your browser offers, you can delete them easily. Use the ↓ key on the keyboard to highlight the offending item, then press the Del key to delete it from the list. I've confirmed this works at least in Chrome, Firefox and Internet Explorer.

2011-11-28: Virtual Server 2005: The virtual machine could not be started. An unexpected error occurred.

Posted at 2011-11-28 15:18:38 by SHD

I routinely use Microsoft Virtual Server 2005 R2 SP1 to run a handful of virtual machines for development and testing purposes. One of these VMs is set to run automatically at system boot. Every once in a while, it refuses to start up.
