Where Intel Processors Fail At Math (Again)

jbengt Re:Exact mathematical value isn't the ideal (238 comments)

The whole problem is that you may have been reading an article written by a blogger who made some rather idiotic assumptions about the precision of the sine function.

The only incorrect assumption the blogger made was that Intel's documentation stating the precision of their implementation of the sine function was correct.

Where Intel Processors Fail At Math (Again)

jbengt Re:example from TFA. try it (238 comments)

But even then, it does not really make sense to discuss the precision near special values such as PI/2 because the precision of your input data will be unrealiable around that number.

In the subject case, though, the input was precise because it was a purely mathematical operation to illustrate a technique for converging towards the exact value of Pi. The misleading documentation led the author to believe that the technique should work using a compiler that uses Intel's FSIN(), but doesn't. He also found out that some compilers avoid the issue.

The Era of Saturday Morning Cartoons Is Dead

jbengt Re:Rose Glasses (320 comments)

It is clearly slapstick violence, and I believe even kids can tell the difference.

You're belief is incorrect, for younger kids, anyway.

The Era of Saturday Morning Cartoons Is Dead

jbengt Re:Speaking for myself (320 comments)

I was just about to say the same. Also, most of the best Bugs Bunny 'toons and other Looney Tunes were originally movie shorts made to play in the theater.

Nearly 2,000 Chicago Flights Canceled After Worker Sets Fire At Radar Center

jbengt Re:what a difference a day makes (223 comments)

The people you're talking about go through a ton of screening before being allowed onto an aircraft.

If by "a ton of screening" you mean a fingerprint check and signing a statement saying you haven't been convicted of felonies like murder, arson, & hijacking in the last ten years, then yeah, a ton of screening.

jbengt Re: Taxing the Congested Skies (223 comments)

You do realize that most of the taxes and fees on your airline ticket go to things like building, maintaining, and staffing airports, traffic control centers, etc? So these are legitimate expenses of running an airline that would be built into the cost of a ticket one way or another.

US Patent Office Seeking Consultant That Can Stamp Out Fraud By Patent Examiners

Sounds more like private industry, where such behavior wouldn't even raise a hint of scandal.

The Great Taxi Upheaval

jbengt Re:Medallions (218 comments)

Talking to a Chicago cab driver of 28 years, what happened was a Russian bought 80% of all cabs in the city. He talked to the mayor and a year later there was a medallion law in Chicago costing $800k to operate a new cab.

I believe you have been misinformed. Chicago licenses cabs for a normal fee, not hundreds of thousands of dollars, but they have limited the number available (on some theory/excuse like that can drivers can't make a living if there are too many of them). Anyway, Many years ago, when Yellow Cab / Checker Cab had almost all the medallions, Chicago decided to expand the number of medallions, and held a lottery to give them out. Licensed cab drivers with so many years of experience had first shot in the lottery - not sure if the odds were weighted or not (for things like years of cab driving experience or military service). Anyway, my wife's step-father won one and sold it for $20,000. Medallions are bought and sold on the open market, and those prices have risen a lot lately. They are now around $300,000 each. The city of Chicago records the sales but does not make that money.

Amazon's Ambitious Bets Pile Up, and Its Losses Swell

Accounting tip: infrastructure investment doesn't show up in a profit and loss statement.

Actually it does show up there, but it's amortized over several years/decades.

Will Your Next Car Be Covered In Morphing Dimples?

jbengt Re:If dimples have this big an effect (138 comments)

Aircraft are not blunt objects, so they don't need as much help in keeping the airflow attached. Wings often have little angled vanes, (which do a better, more precise job of mixing high speed air into the boundary layer than dimples do) in order to keep the flow from detaching, and to keep the air moving across the wing rather than along it.
