A client of my IT-consulting service owns a web-development shop. He's been having problems with a Slackware 12.0 server running MySQL 5.0.67. The machine was set up by the client's sysadmin, who left on bad terms. My client no longer employs a sysadmin.
As far as I can tell, the only copy of MySQL…

Both SQL Servers are the same version of MS SQL…

Computers have trouble storing fractional numbers where the denominator is something other than a solution to 2^x. This is because the first digit after the decimal is worth 1/2, the second 1/4 (or 1/(2^1) and 1/(2^2)) etc.
Why deal with all sorts of rounding errors when the computer could have…

Hi,
On one (old OS X 10.4) server I'm tarring up some files which have ACLs. I'm then using ``tar -xp'' to untar the archive onto a new 10.6 server, which doesn't have any users/groups configured on it yet except the default admin (UID 501) (there's a reason for that, don't ask!). Obviously this…

if($('#Field').val() != "")

if($('#Field').val().match('^(0|[1-9][0-9]*)$'))
