Poul-Henning Kamp, of FreeBSD fame, posted a year-end question (in Danish) on his blog at the IT rag What would be the computer equivalent of Shannon’s ultimate machine?

Another day, another application that insists on having to count every single object in the db/filesystem/whatever, just to show me a progress bar as it copies/updates/deletes something.
I. Don’t. Care.
Really. I just want you to get started on your task and get the job done.
If you insist on showing a progress bar, fine. But then get [...]

“The ATTACK query is an undocumented feature of the development branch of MySQL…”

PHP array_merge is Slow

Wednesday, April 30th, 2008

We grab a number of data from two different MySQL servers, get them back as arrays ($ar1 and $ar2) and then we concatenate the two arrays. $ar1 consists of 30 to 200 elements, sometimes more. $ar2 typically contains 30 elements.
The PHP way [...]
