Sorry, he isn't wrong. You don't do exact byte-for-byte comparisons. You do regular signal analysis and see how close the audio is to each other. If it exceeds a given deviation, you alert them.
First of all, the standard for speech quality is PESQ or Perceptual Evaluation of Speech Quality (ITU-T P.862). In PESQ, you don't just, "see how close the audio is to each other". There's a lot of things that need to be done to both the input and reference signals before you can begin analysis.
First, the input and reference signal levels are aligned to a constant sound pressure level of 79dB. Secondly, filtering is performed to take into account things like the effect of the electrical and acoustic components of the handset. Next, delay is taken into account by detecting voice activity and aligning the parts of the signal that match. Then the signals are transformed to match certain properties of the human ear to get a sensation surface, and any loud sections are realigned. Finally, the parts of the signal with negligable effect on quality are equalized. Once all that is done, then the sensation surfaces of the signals are analyzed to find the MOS.
It's not just sending files around and diffing them like the OP implied. Oh, yeah, and you need to license the algorithm.
Incidentally, does anyone know why the first entry in the Atom feed is always a link to the Google News front page?
Since the same information is in the feed's link, it's kind of superfluous. Is there some reason for this or is it just a mistake?
They appear to use NFE for the feeds. Is this a default in NFE?
And wrong. Telephony systems aren't like file systems. You can't just receive a file, compare the output with the original, and assume that there's a problem if it doesn't pass. In telephony systems, there may be format translations or echo cancellation done on the voice channel, which may change the output, but are not indicative of a problem. Depending on how his network is set up, the voice channel may even be routed through analog equipment. If this is the case, you won't ever get the same sound as what you put into the other end.
This web page has about 2500 English words, so it is
convoying more information (although I can't speak to the quality of that information).
But English is a very silly language...
That's not really how you use that word. His spell checker must have provided negative information.
Actualy I did call the police they didnt want to do anything at all... I guess lazy ?
That's not good. They very should be concerned about a prisoner actively trying to commit fraud. Someone dropped the ball, and should be punished accordingly.
Write a letter to your police commissioner, describing the situation and what his unit isn't doing about it. Then CC the letter to your state's attorney general, and the local paper. Someone will take notice at that point.
You could also call the prison and complain to the warden.
This page hit a note with me though as two weeks ago I got a phone call from "Miami/Dade County Correctional" at any rate out of curriosity I accepted the collect call and some one potraying themselves as a police officer said that some one was in the hospital yadda yadda yadda and tried to get me to dial a number *76 something something LOL
Did you call the police? I'm sure they'd be interested in a person at a correctional facility who poses as a law enforcement officer and attempts to defraud people using prison phone facilities.
I believe you have confuse Steve Jobs with another co-founder Steve Wozniak. Steve Jobs is the marketing guru while Steve Wozniak is the technical guy, who created the Apple I & II and wrote sweet-16.
You are correct, of course, and I should have geek points subtracted for that typo.
According to the old Byte Magazine, Woz wrote sweet-16 for Apple II because it is a 8 bits machine and he need to use a 16 bits pointer to address the memory.
Let's see if I can get some geek points back by quoting the actual manual of SWEET16:
SWEET16 - THE 6502 DREAM MACHINE
While writing APPLE BASIC for a 6502 microprocesor I repeatedly encountered a variant of MURPHY'S LAW. Briefly stated, any routine operating on 16-bit data will require at least twice the code that it should. Programs making extensive use of 16-bit pointers (such as compilers, editors, and assemblers) are included in this category. In my case, even the addition of a few double-byte instructions to the 6502 would have only slightly alleviated the problem. What I really needed was a 6502/RCA 1800 hybrid - a powerful 8-bit data handler complemented by an easy to use processor with an abundance of 16-bit registers and excellent pointer capability. My solution was to implement a non-existent (meta) 16-bit processor in software, interpreter style, which I call SWEET16.
Bill Gates was a good coder, as were many of the early Microsoft coders. Look at analysis of Altair BASIC and see how they used all kinds of optimisation tricks to get as much as possible into the limited RAM of the Altair.
Microsoft also made Applesoft Basic for the Apple II in 1977. It had so many defects that, there was a cottage industry for products that fixed Applesoft bugs.
I sure hope Bill wasn't involved with that one.
Incidentally, Steve Jobs could also code. He wrote some pretty neat software, too. He wrote a limited 16-bit virtual machine for the Apple II (an 8-bit machine) called "Sweet 16".
I'll be reading along and all of a sudden the lack of a period after Mr. or, if I quote the first sentence of the book, "Some years ago there was in the city of York a society of magicians." I must be dense, but I had to read it twice to actually understand what Clarke was saying.
That didn't bother me nearly as much as her use of the word, "chuse".
The sentence structure, the grammar, it all just appears very foreign. Is this a normal British thing? I'm honestly at a loss.
Her writing is not entirely indicative of her locale. She's trying to emulate the style of early 19th century writing. If you read some classics from that era, they seem remarkably similar in style to hers, regardless of their country of origin. Even later works, such as as those by Poe, are similar. The style is also similar to that of later British authors. For instance, early 20th century writing, like Arthur Conan Doyle's, has similar sentence structure. However, Clarke's writing is not similar to later British writers, such as Peter F. Hamilton.
Does anyone think it's odd that of the last seven stories, not a single one has a comment modded higher than 3? What's up?
There's a couple of moderations up, but I don't see any downmods. We might be able to say anything we want without fear of being modded down!
Lets test this:
I have just poured HOT GRITS down my pants. Thank you. I have just poured HOT GRITS down my pants. Thank you. I have just poured HOT GRITS down my pants. Thank you.

Both Sedna and 2003 EL61 are smaller than Pluto and not considered planets.
The new KBO, 2003 UB313, is larger than Pluto, which is why the discoverers are considering it a planet.
They also discovered Sedna, so they would probably know.

That Red's gonna run, I can always tell.
The best part is that his last name is derived from the Greek word proktos, which means anus.
+ one American dude who actually reads liner notes...

Yes, PVD is WAY nicer, but it's usually $200 more. :(

In a word: No.
The discovers of both tell all.

The best know case is Dactyl.
The model I linked to comes with a PCMCIA CF adapter and Windows drivers for ME, 2000, and XP.
This is possibly an indication that my hypothesis has failed to soldify into a viable theory.

I look forward to seeing that quote in a Bill Griffith cartoon:
