The G4 (and presumable the PPC970) has the Altivec unit which provides significantly more vector registers, operates on vectors double the size, and is capable of running vector operatons on multiple execution units.
No - the IBM PPC chips don't have the Altivec unit. They are only on the Motorola chips. That is why Apple currently doesn't the the faster IBM chips.
The reason for the limit isn't the display technology. We have better displays now. There are several reasons that HDTV is limited to those resolutions.
1. Broadcasting equipment is expensive. The equipment on our end doesn't ever hit economy of scale.
2. We only get 6 megahertz of specrum. When you factor out forward error correction that only leaves 19.39 megabibs of data using MPEG 2. When we work in-house we use at least 50 megabits (of MPEG 2) for HD streams. If we tried to broadcast a higher resolution we would have to "squeeze" it even harder. And no one wants their HDTV to look like DirecTV.
3. Their has to be some kind of standard so that everyone knows what we are aiming at. We don't want someone to pull and "embrace and extend" on TV. Wouldn't you be pissed if I made a TV transmitter that could only be tuned in by the TVs that paid me for a license, and then I sold the transmitter cheap to the stations in your area?
4. Computers are expected to break - ask any normal user. In TV we don't have that luxury. People expect their TV to come on and work flawlessly every time.
The reason for gold contacts is corrosion resistance. If you hook up your equipment with steel, aluminum or copper connectors and let it set for several years the connectors will start to corrode and the signal quality will start to degrade. You won't notice a difference immediately.
I think that you need to go back and reread that comment. He isn't saying that the tuner is simple. He is saying that in most cases the HD tuner is outside the display. This will change with the FCC mandate that all TVs have a digital tuner intergrated.
According to the training that I have received to be a manager at a large university, if your manager tells you that you can sue not only the company but also the manager. In fact the catch phrase for the four day training was "If you do [fill in illegal thing here] you run the risk of losing you home, your car, your boat, etc.". Made me not want to be a a manager any more.
From my experience (in Indiana) that isn't the way that these reviews work. I work for Indiana University and we just finished a state and federal review of EVERY position (~80,000 jobs). Several people got reclassified and the university was forced to create a new employee type to cover all the people that they are now required to pay overtime.
I use both Linux and Windows on the desktop, but a significant portion of my job is support of 60+ users running mostly Windows 2000 (and some XP Pro - but no 9x). A lot of the time it's not as easy as pulling up task manager and killing the offending app. A lot of times this will leave the system in an unstable state (but restartable) and some times it just plain doesn't work. We also run several applications in DOS boxes or telneted into a UNIX box, so I am reluctant to tell people to just kill off applications that aren't responding. Although I must say that it would really suck to have to tell people "type ps -ef | grep winword.exe and get the process ID then type kill -5 that number". But I guess that if they were running Linux I could ssh in and kill it myself.
I see people say this all the time and I wonder what causes Windows to crash so much for them. I have five 98 SE and Me machines networked with high-end (cutting edge) hardware at home for gamming. We will run some pretty intense games (Homeworld, Delta Force Land Warrior, MechWarrior 4, etc.) for hours (some times 12+ hours) without any problems.
I could understand if you are the type of user that burns a CD while browsing the web, chatting on IRC and editing graphics in Photoshop.
This is not flamebait - I am just trying to understand why so many people have such drastically different results then me.
I agree with all your points, with the exception of "than the traditional hit the reset button that happens with Windows 3-4 times a day". The Windows 2000 Workstation on my desk will run for weeks without a restart. Normally I only restart to install security fixes. Now this isn't as good as my Linux computers, but it isn't 3-4 times a day.
If I had to restart it that many times a day I would probably fix it and not just complain about it.
Don't complain about FUD and then spread it yourself.
No, when its done without the permission of the copyright holder it is pirating.
When it is done with permission it is call an over-priced souvenir.
Like it or not this is the way thing work. Don't think that it should work this way? Try to change it - don't just bitch about it.

I always check the oven before I turn it on. When I was growing up my mom would put frying pans in there to cool down. I only had to bake a couple of pans before I started checking every time I wanted to use the oven.
I would like to think that is the way they would choose to write the law. Unfortunately I think that it will be more like the cable box laws. They make cable boxes illegal to make, own or use.
I see this argument all the time, and it is only partially true. By your example knives are legal, but switch blade knives aren't legal in most states. In most states it is illegal to carry a concealed knife with a blade over a certain length (usually around six inches) without a concealed weapons permit. There are some tools that are made that are only legal to possess if you have certain licensees. There are also a lot of items that are legal to possess if they are used for a legal means but are illegal to possess if they are used to break the law (lock picks, drug paraphernalia). Cable descramblers are illegal even though they are just a collection of common electronics parts just because they are used for an illegal end.
Currently Kazaa (and other P2P software) doesn't fall into any of these categories, but that is just because they haven't decided to make it illegal.
One problem that I haven't seen anyone mention is that 802.11b is shared bandwidth.

Why VHS Was Better

· Score: 1
The NTSC spec only allows for 480 lines of resolution to be displayed on the screen. The total lines are 525, but that includes 45 in the VBI (vertical blanking interval). That said, a good standard VHS deck (not S-VHS) uses ~180 lines.
The high end ($45,000 for the body, not including the pedestal and lens) Sony cameras we use at work only output ~350 lines.
I had a friend in high school that could walk up to a home, business or pad lock and open ~90% in less than 30 seconds with a pick and wrench. all it take is a delicate touch and lot of practice.
While I agree that it would be best if we could resolve our differences another way -- if someone has to die, I would much prefer that was the other guy.
It won't be in better shape for very long. The F16 is an aerodynamically unstable plane that is only able to fly using computers and fly-by-wire systems.

Random number generators aren't truly random - they will eventually repeat. This would make things an incredible amount harder, but not impossible.

Only if they fire everyone that comes in 5 minutes late from lunch. If not it is retaliation. Then you qualify for punitive damages.

But if you're dealing with a standalone Linux machine and something has eaten X, you have no alternative but to reboot.
The next time try ctrl+alt+backspace to kill X. Not an ideal solution, but doesn't require a reboot.

At no point did I say that it didn't matter how we conduct ourself. But in the end if dieing has to happen, I would rather it be the other guy.
The thing is HDTV is normally ~19Mbps. I can be done with less (I have seen it as low as 12), but compression artifacts start becoming substantial.
While I agree that it would be best if we could resolve our differences another way -- if someone has to die, I would much prefer that was the other guy.
I don't know that I would call Hellfire missiles "very light armament".
It won't be in better shape for very long. The F16 is an aerodynamically unstable plane that is only able to fly using computers and fly-by-wire systems.
I agree with your numbers, but DVDs aren't HDTV. HDTV is 720 vertical lines minimum. DVDs are 480 lines.
