Knuth Got It Wrong 298

davecb writes "Think you've mastered the art of server performance? Think again. Poul-Henning Kamp, in an article at ACM Queue, finds an off-by-ten error in btrees, because they fail to take virtual memory into account. And he solves the problem in the open source 'Varnish' HTTP accelerator, for all of us to see and use."

Comment Overreacting? (Score 1) 391

Am I the only person to think that the woman is obviously and grotesquely altered and therefore find it far more comical than offensive? Looks like she's standing in front of a carnival mirror.

I find it hard to believe that the intent of the creator was to depict an actual, attractive female.

If I actually met such a person, the first thought through my mind would be "serious thyroid problem." And do my best to make sure they didn't tip over.

Reminds me of the scene in 2001 when the flying bone-club segues to the orbital view.

Well, if the leak is small enough, investing in a bit bucket might be a viable option.

Comment We Did Something Similar (Score 1) 262

Not too long ago I worked for a company that would take OEM (Gilbarco, Tokheim, etc.) gasoline pump parts (pcbs, panels, buttons, etc.) and send them to Shenzhen, China, to be ripped apart, analyzed and remade. IMO the recreated parts were better than the original.

So rather than trying to convince OEMs to modify their designs for your purposes, buy one, send it to such a company and pay FAR less while getting exactly what you need with full control over the manufacturing process.

"Why don't you find someone who understands English and ask them how many ways to interpret "Chimps Have a Built-In GPS" they can think of?"

OK. Did that. Here's the conversation verbatim:

Me: Could you read this one paragraph (Slashdot title and summary)?
Coworker: [reads] OK?
Me: After reading that blurb, would you say that the writers are implying that a chimp could be dropped somewhere in Michigan and know how to get to some other point?
Coworker: Uh
Me: Thanks.

Any other bright ideas?

Thank you Captain Literal.

Do you really think anyone meant to imply primates have, in their brains, something commensurate with features found in a Garmin?

"Bullshit summary again. Or maybe bullshit article. Who cares? After a while, you don't bother."

I think we just found your problem...

" was routine for me to lie to customers, change prices, say we didn't have something and stare at it, laughing all the while with my manager. I didn't particularly find it funny, but I needed the money. I quit that as fast as I can like any other respectable person."

Am I going out on a limb by thinking a respectable person wouldn't have routinely lied, for money, in the first place?

Many people are unenthusiastic about their work.
