Fees disguised as taxes

It has become customary in the telecommunications industry to quote a low price and then add half as much to it in "fees". Regulatory Programs Fee. It sure sounds like a government tax. It isn't. There's been a new round of official-sounding line items on telephone bills, which are really just ways for telephone companies ...

Why does the Links folder keep re-creating itself?

June 30, 2004 Jun 30, 2004 06/30/04
Raymond Chen
Those of you who dislike the Links folder have probably tried to delete it, only to discover that it keeps coming back. Why is that? This is Internet Explorer trying to do some auto-repair. It noticed that the Links folder is missing, so it figures, "Gosh, it must be corrupted! I'd better fix the problem by creating a replacement." ...

It's like stupid warning labels on consumer products: Once you read the warning label, you can already imagine the lawsuit that required the warning label to be written in the first place.Use that same imagination to interpret this Windows XP SP2 setup error message.[Dumb typo in title fixed 7:43am...

The difference between thread-safety and re-entrancy

June 29, 2004 Jun 29, 2004 06/29/04
Raymond Chen
An operation is "thread-safe" if it can be performed from multiplethreads safely, even if the calls happen simultaneously on multiplethreads.An operation is re-entrant if it can be performed while the operationis already in progress (perhaps in another context).This is a stronger concept than thread-safety,because the second attempt ...

When does SHLoadInProc unload a DLL?

June 28, 2004 Jun 28, 2004 06/28/04
Raymond Chen
The SHLoadInProc function instructs Explorer to create an instance of a particular CLSID. This causes the DLL responsible for that CLSID to be loaded. But when is it unloaded? This is one of those puzzles you should be able to figure out by thinking about it. Consider: The object is created by calling CoCreateInstance and then...

Ringside seats at Fruit Fly Fight Club

June 28, 2004 Jun 28, 2004 06/28/04
Raymond Chen
The first rule of Fruit Fly Fight Club: Flies can't talk about Fruit Fly Fight Club. Because they can't talk at all. At least not to humans. Researchers at Harvard Medical School took a break from studying lobster fighting and shifted their focus to fruit fly fights, and even mutant fruit fly fights. (Via The Annals of ...

Hong Kong crocodile caught at last.

June 25, 2004 Jun 25, 2004 06/25/04
Raymond Chen
After over half a year of eluding experts, the Hong Kong crocodile was caught at last. What amused me was that the article said that the creature had eluded an expert crocodile hunter from Australia named... John Lever? (Curiously, in this article, he is given credit for capturing the croc.) Not the self-proclaimed Crocodile ...

From there, click the Advanced button and go to the Monitor tab. From there, you can adjust your screen refresh rate. As a rule of thumb, higher refresh rates are less likely to cause eyestrain.
