Keep in mind that overclocking by 2x drains the batteries by 2x as well.
It's not linear and there are a lot of factors. The switching current goes up by a factor of four for every frequency doubling. There's leakage current that stays constant regardless of clock, I think. And that's not saying anything about the rest of the circuits that might not be on the same clock, the CPU might not be a huge power drain in some circuits.
The high RPM drives apparently are still a bitch to make. It is easy to make the motors spin that fast, but being able to read and write data at a tight areal density is tough. The older 15k RPM drives aren't necessarily all that fast. I have a couple older 9GB 10kRPM drives and they are sloooow, newer 7.2k RPM drives beat it in just about everything.
The rovers are slow because they are doing near archeological level of meticulous detail. Scrape here, measure this, run a spectrometer on that, take pictures and move to the next rock. Solar power doesn't afford a lot of power either.
With an airplane, you need to have good landing and takeoff areas, I'd hate to see the plane stuck with some unexpected obstacle. Taking off and landing every so often, with heavy equipment in thin martian air doesn't sound like a recipe for success. Just staying in the air with just a camera seems pointless if you could use a mapping satellite.
It's the same reason my son and I built him a PC for xmas
Wait a minute, is your son going to be bursting with pride over a PC you assembled for him? I'm not sure what the accomplishment is to be able to assemble a PC, putting together a bunch of off-the-shelf components doesn't necessarily make a custom unit. It kind of annoys me is people talk about "building" a PC when it is just rote assembly. I take it as being on the order of a novice modeller saying they just built a snap-tite model, it just doesn't ring as anything special to me, no special skills required. I don't think putting together a system enhances one's knowledge of the underlying technology and principles any more than putting together a sandwich enhances the understanding of how bread is made.
You build stuff for yourself to learn and because it's satisfying to make stuff... the same reason other people work in wood or in wool or whatever... I think we forget this sort of stuff in our modern mass produced world.
Interestingly enough, most people are using mass produced parts and tools to "make" stuff. With electronics, it is really silly to try to go homemade with everything, I don't know anyone that can fab a transistor, much less an IC.
You have a point, but I don't think soldering together someone else's project design helps anyone learn the underlying principles of the design, any more than Toyota's assembly line people know how to design a car. Not that they are dumb, doing the assembly just doesn't cut it.
I think you do have a point, but the implication is still there. I don't like the ACLU's handling on several issues, or how they twist words, but their opponents twist words too.
Consider the political motivations of the people that placed the stickers there. The people that place that sticker there are trying desperately hard to push creationism as science and as a valid theory. I don't believe it is, as none of their claims I've seen present viable facts that back up those claims, thus it is not elevated to the scientific definition of theory. Another sticking issue for me is that the creationists I've met not only tend to focus solely on picking apart evolution and and modern cosmology, they use flawed reasoning, incorrect facts, and don't present a sufficient argument that creationism explains all the facts better. Where a typical scientist should be willing to hone and refine knowledge so that it fits with reality, creationists tend to try to sledgehammer the square peg of their knowledge to the round hole of reality.
I don't think unused potential is necessarily a bad thing. The 3D section of the GPU that's not being used doesn't waste so much power.
I'd like to know what they think they are doing to justify a 3D user interface before rendering justice though. While there may be advantages to 3D interfaces of sorts, from Microsoft, I expect it to be useless eyecandy like XP's "look".
I don't want anything to have 98% market share. I'd say a split between four major browsers, hovering around 25% each would do the most good. Hopefully they would all be standards compliant and worth supporting and should a serious vulnerability be discovered, there are three alternatives to use while a patch is made.
step outside the normal 1-11 channels. Channels 12 - 14 are almost guaranteed to be empty.
It doesn't work that way. Each channel is spaced 5MHz from the last, but WiFi uses 30MHz bandwidth. Someone using using channel 11 is still overlapping more than half of your needed bandwidth, even if you use channel 14.
Don't forget the Connection Machines. They had at least one face that was just a bunch of red LEDs. They were mentioned and were in the background of Jurassic Park.
The standard PC slot cards are expensive enough as it is, I wonder why try to shrink it even more. There aren't a whole lot of TV tuners, much less HD tuners for PCMCIA, I wonder what about Express card will make those more available. HDTV doesn't need slot bandwidth unless maybe if it is decoded on-card, the broadcast bitstream is only 20Mbps.
Maybe I'll be interested if they actually bother to put more than two slots on laptops. It's bad enough that so many laptops seem to have only one mini-pci slot and one Cardbus slot.
I don't think the total number of broadband connections means much if the US simply has the largest post-industrial population.
China isn't a superpower (yet). IIRC, a much greater percentage of Chinese are pretty poor. China does have great wealth, but I think a greater disparity than the US.
It's a well established fact that the porn industry leads the rest of the pack when it comes to embracing technology and making money off of it.
It isn't exactly a feat when the production budget is a few thousand dollars and a few day's time at best to produce from start to finish, and they charge $25 or more for half an hour's worth of video. In short, if you have a market that will pay so much for so little, it's not hard to profit.
Now, I don't know about whether HD would just show the flaws on the models, there is more detail, but not that much detail. How much detail can be had with a 2 megapixel camera?
I see multi-angle often as extras to show differenet stages of animation, from sketches to animatics to line drawings and fully painted. Disney's Beauty and the Beast DVD was a full-length multi-angle movie with branching to accomodate the different versions.
LCD screens deal better with bad environments then CRT as they run cooler, but they aren't what you would consider cheap.
Used CRTs are so cheap now that it's not even a concern for me. I've never seen heat be an issue, I've seen CRTs last a long time in industrial environments. Cost being an issue, I wouldn't expose an LCD to an industrial environment, especially given their cost.
Right now, I am using a Compaq Deskpro convertible tower. At 400MHz, the only thing that is actively cooled is the power supply. It was only $40 shipped from eBay a few months ago. I have it hooked up to a second hand 19" CRT. The keyboard and mouse are just standard second hand. They are so cheap, it doesn't matter, but still, in my shop, they last a long time before needing replacement, usually several years.
If dust and grease is a big concern, just get a small sheet to cover the computer system when not in use, and maybe a sheet for the keyboard and mouse when entry isn't needed.
For absolute resolution, a panel is the best way to go. It is true that projectors wash out more easily, generally not to be used at a brightly lit room, like at a convention like this.
The cost for screen area does go to projectors though. Watching videos is where absolute resolution doesn't matter so much (1920x1080 for HDTV, DVD is 720x480), but a larger screen makes it easier for more people to watch and be better immersed.
Projectors are far better for arraying in terms of joining, but there are still some issues, such as barrel distortion. A straight line projected through a lens will end up curved, particularly at the borders.
I'm curious what it takes to make a no-edge-molding LCD display, such that the edge of the image is the edge of the panel for near-seemless joining.
There are people that simply don't care about anyone other than themselves. They simply don't or can't put themselves in the shoes of the people they deal with. Often, this type of is called a sociopath or psychopath.
Closely related, there are also people that truly have malicious intent against others. They'll do anything they can to benefit themselves.
One thing that is scary is the number of messages it takes to get a large bill. If SMS messages cost 10 cents to send and 10 cents to recieve, an $800 bill one month means 8000 messages or nearly 270 messages a day.
I've never found a phone keypad I liked, I can't stand punching in one SMS message, never mind several per day.
I think the firmware should be upgradeable, the question is whether Belkin should be trusted. I've avoided buying any of their products after they've made a firewall that deliberately served up adware.
If you agree with the Slashdot mantra that nothing is safe, you don't need cameras to learn the stuff you suggest. Not having the cameras makes it a little harder, not impossible.
Actually, there is a point. Nearly any Radeon can unload half the CPU needs for decoding over the air broadcasts. nVidia did not put this in until their 6xxx series. A single 2GHz P4 should be able to decode OTA transmissions on their own.

I've seen interviews that said other things, such as adopting a daughter and other projects. He's got THX, ILM and recording studios too.

I wouldn't mind giving him a shot, but as rap / hip-hop isn't my thing, I have to hear a sample first. The MP3 links on that site are dead.

What's the maximum resolution you can get with a projector?
Courtesy of Projector Central, the current max is:
JVC DLA-QX1G $ 225,000 187.4 lb weight 2048x1536 7000 lumens
Of course, you can get a 1920x1080 projector for an eight of that, or a 1400x1050:
JVC DLA-SX21SU $ 11,995 13.0 lbs 1400x1050 1500 lumens
There are various projects that support monitor arrays, some of them require multiple computers though.
Projectors are far better for arraying in terms of joining, but there are still some issues, such as barrel distortion. A straight line projected through a lens will end up curved, particularly at the borders.
