Grab a sudo shell and stay there: [shell]$ sudo -s [/shell]. So much nicer than [shell]$ sudo su[/shell] - it keeps all of your environment variables!

So general it cannot be fixed.

PHP's PDO library (MySQL driver) has been throwing strange exceptions for any insert/update/delete queries:
Database error: SQLSTATE[HY000]: General error
It doesn't matter what the query is. [php]$stmt = $pdo->prepare(); $stmt->execute()[/php] seems to be the problem, but the exception is also thrown with [php]$pdo->exec()[/php] and [php]$pdo->query()[/php]. Persistent connections don't make a difference. Running the query from the mysql command line is fine.

Surprise!

POP Quiz time! How do these three bits of HTML get parsed?
  1. <foo bar=baz/> (no space between the value and the slash
  2. <foo bar=baz /> (space after the unquoted value)
  3. <foo bar="baz"/> (quoted attribute value)
The value of the bar attribute in the first example is literally “baz/” with the slash, and no errors or warnings are generated. The second and third ones are parsed out as “baz” as most people would probably expect.
