The Fat Mac had neither a hard drive nor cooperative multitasking (unless you count desk accessories, but the original Mac had those too). There was Switcher which gave the ability to switch between apps, but there was no multitasking -- the background apps were completely suspended. Cooperative multitasking didn't come 'til Multifinder with System 6.
Internal hard drives didn't come 'til, I want to say Mac II? Was there one for the SE?
This sentence is actually intelligible to people who know proper English.
Just as important, officials and private experts say, the small rocket for astronauts would be at least 10 times as safe as the shuttle, whose odds of disaster are estimated at roughly 1 in 100.
The whose in this sentence refers to the Shuttle, meaning that it's the Shuttle which has 1 in 100 odds of disaster, not the replacement.
Not to defend the guy, but I just took a look at the docstar website and I suspect what he was talking about is a digital signature stored for every document. It's not security in the sense that "no one can read this document." but rather security in the sense that "no one can modify this document (even a 'single pixel') without it being detected."
I don't suppose he tested the torque of the motor to see how quickly he could get the record to playing speed. That's one of the key features that I understand to be important to audiophiles
I think that audiophiles would be more interested in the stability of the system (meaning that there's no variation in the turning speed) than in startup time. DJ's on the other hand...
Coyotos does away with Persistence, though, which is what gives the "restart where I left off" capabilities. BTW, there's a paper on the design of EROS's storage mechanism here (sorry, PDF).
D'oh. I've been working with 4:4:4 recently: HDCAM SR and some CGI stuff. But yeah, I assume in this case we're talking about IMX which is the only mainstream 50Mb MPEG2/i frame format around.
You were calculating data per FRAME not per second, and at only 8 bits per channel, no less. Multiply by 30 for the 8 bit/channel total bit/sec, or replace the 24 with a 30 and do the same for the 10 bit/channel rate.
My involvement is on the production end, so my knowledge of the actual broadcast side is a little sketchy. It is true that even before getting to the broadcaster any video is compressed -- there is no uncompressed tape format used for delivery. Most common is Panasonic D5 which is 235Mb/sec (proprietary codec), and the up-and-coming format is Sony's HDCAM-SR which is 400Mb/sec of I-frame only MPEG-4. The uncompressed stream 1.5 Gb/sec. It is entirely possible that there are high-bit rate MPEG-2 streams used for transmission from one facility to another on the way to the satellite, I'm really not sure. The point I really wanted to make was that the 19Mb (or less!) stream isn't being recompressed -- it looks pretty bad as it is, you really wouldn't want to do that.
Oh, and the 1080 format used for transmission is 1080i. 1080P is used often for production but is not a transmission format (yet). The data rate for 1080i and 720P is the same (720 has half the pixels but double the frames/sec of 1080i). 720P can be compressed much more efficiently, however, (interlacing is hell on codecs) so it is possible to use a lower-bitrate MPEG stream, or you can get better quality at the same bit rate. This is why the EBU (European Broadcasting Union) is reportedly on the verge of standardizing on 720P as their sole Hd broadcasting standard.
Yes, though not at the specific data rates used for broadcast. In general MPEG4 is vastly superior to MPEG2, however. Also, an MPEG2 stream would never be recompressed as MPEG4, the broadcaster would feed the uncompressed signal into the MPEG4 compressor. All in all this is a move to increase quality at the same bandwidth.
Well, the iTMS would be pretty useless if you couldn't make CD's from it. I think they don't see CD players as direct competition for the iPod. They see file-based players as the future, and they want to prevent anything other than the iPod from gaining traction for as long as possible.
It's pretty smart from a business point of view: the store supports the iPod since it's the only player that can directly play the music, and the iPod supports the store since it's the only mainstream store that supplies music that can be played directly on the iPod. They'd like to keep that synergy for as long as possible.
I doubt that they really care that much if you rip off the RIAA or whatever, but what they do care about is getting you to build up a library of music that can be played back on your iPod and no other portable player. They have always said that they didn't expect to make money on the ITMS, that it was to encourage people to buy iPods. Well, what better way to encourage them to let them build up large libraries of music that must be played back on an iPod?
So I'm stuck with a file system that is incompatible with every other Unix system on the planet because you choose to use poorly written software?
Not to enter the fray, but I'd thought I'd point out that it's possible to format a partition with a case-sensitive version of HFS+ if you need it (not recommended for the boot partition).
For this reason, if I'm ever traveling and have to use a computer in a cafe or something, instead of typing my password, I'll open a text editor and type a bunch of random gibberish and copy and paste my password one letter at a time. It's really tedious, but so far I haven't had an account compromised. (I also change my password before and after traveling, just in case).
AFAIK, there is no huffman table in jpeg and the compression is good old RLE. (As in what we used to use on Compuserve before they invented GIF). I didn't read the article, but I suspect that they are in fact replacing RLE with something like huffman encoding, but I seriously doubt that they would have an optimized table for each image since storing the table would offset too much of the space saved from the better compression.
Note, the USD isnt real, its been fake since 1913 when federal reserve was setup privately, its just paper only worth the trust of the govt in getting income taxes to pay for it.
Um, I hate to tell you this, but while the US$ may not be "real" in the sense that it directly represents an actual commodity, there is no less trust involved in a gold-backed currency. First of all, how do you actually verify that the apparently gold-backed dollars in your wallet are actually backed by gold? You'd have to turn them in and trust that you'd actually get some amount of gold in exchange. And how do you know that the gold you own is actually worth something? While gold is actually useful, it certainly doesn't have enough intrinsic value to justify its market price. It's value is primarily derived from the speculation of others like you who trust that it will have some enduring value and is therefor a safe investment.
An interesting story: a friend and co-worker of mine is from Bosnia, and lived with his family in Sarajevo during the war. His mother had saved her gold and jewels believing that they would help them during (or after) the siege. Before the end, however, she ended up trading most of them (they'd be worth a couple thousand dollars, now) for a dozen eggs. It just goes to show the extent to which the relative value of anything can change based on the current situation.

where's the any key?
OK, I'll be on my way now...
Tell me about it. I live in brooklyn. Going to the movies for us:
$21 for tickets (10.50 a piece)
$40 for dinner (no movie popcorn for us)
$50 for a sitter
We do this about once a week. It's worth it for us, but that eats up a good chunk of our discretionary cash.

Um, because Shake only runs on Linux (and OS X of course)?

Hey, don't talk about my parents that way!
Actually, I guess I'm actually not that young any more...
that was actually a real comment from an earlier story today -- I remember reading it.
Well, that kind of narrows it down a lot, doesn't it?
Of course you know that he wrote emacs (it's not a clone of anything). Oh, and gcc.

Well, that's my theory, anyway.
And I'm never wrong.
And you know that both of them are preceded by NeXT releasing their Objective-C front-end for GCC under the GPL, right?

I'm much more impressed by this.
