Judging by goggling other announcements they combine the microphone element into the CODEC claiming to have less interference from RF sources. This certainly isn't as big a deal as they are making it out to be, any decent designers already aim to keep the CODEC as close to the MIC as possible where quality and will couple and filter the output to minimize this. On consumer devices MIC interference just isn't such a big deal and in professional applications I don't see this getting the dynamic range that microphones have with 1" or larger elements and properly balanced connections that are used today. Really the only use I see for this is to help space save on cell phones, which is a killer feature in itself to cell phone manufacturers if the price is right.
I know many of us Linux users would like to see it replace Windows as the dominate OS, but frankly, why should we care? We Linux users have a wonderful OS that does everything a big geek like me could want, and far more than Windows can do. Saving Joe Sixpack the $70 he pays Microsoft to buy a machine with Windows pre-loaded isn't a cause I get excited about.
That is all well and good until there is a piece of hardware or software that you want or need to do something on Linux. When making the decisions on what these companies are going to support visibility will have a large impact on if it's supported. That is where the marketing helps.
Instead, a new market will emerge for ultra-cheap computers (as in OLPC). Super-cheap computers with lots of RAM and non-volatile storage will one day cost $100 (in 2007 dollars). When this happens, Microsoft will not be able to compete against free Linux as the dominant OS on these machines. There just isn't enough profit per device to support Microsoft-like company.
In that sort of market Microsoft will push their embedded tools which don't cost $70 but in the $8-20 range. Not to mention people like QNX etc who would love to get their software in boxes like that and are actually spending money to get their name out there. The problem is that the people making the decisions are not the geeks who know about the stuff it will ultimately be the administrators (people who companies like MS and all have been marketing to for years) who have final say on those decisions.
I think Microsoft understands this low-end disruption threat, and that's why they're so desperate to push Windows CE derivatives. However, the bean counters at Microsoft will always try to kill off unprofitable efforts like Windows CE, as the market, margins, and profit just aren't there compared to selling high-end software for high-end machines.
Bull, CE is central to a lot of Microsoft's most recent endeavors, smart phones, car operations and navigation, and will almost certainly find it's way into their Robotics offerings. CE is not going anywhere soon.

Common, the Atari 800 had 4 tone/noise generators not 4 channels of DMA sound. If you are pulling in generated sound into the mix you should also count the 18 channels the YMF262 on the sb16 can generate.
There are RAM drives available that use DRAM, but due to the refresh circuitry and whatnot it takes a bit of power so the battery will only supply power to the RAM for a limited amount of time.
I am well aware that RAM drives are available but that battery on that unit will last you between 4-5 hours and that is only for a maximum of 4 gigs. Once you scale that up to HDD sizes you would need another laptop size battery just to give you enough time to run from outlet to outlet. DRAM just wasn't designed for this kind of thing, is too leaky and inefficient.
The overhead is still there just because it's on the die doesn't make the overhead go away, because of that battery life on PSRAM is much lower then that on battery backed SRAM. As for density, it's in the same boat as SRAM, while higher densities can be made, they typically aren't and you are stuck with in most cases a maximum density of 64-128mbit, much lower then DRAM.
Another problem with battery backed ram is that without the overhead of a quite complex circuit to refresh it only works with the far more expensive, and generally only available in lower densities SRAM.
Well the ammo I mentioned in my post I said was 150gr SP. Kinda hard to get a soft-point bullet with a steel core;).
Missed the SP
What you have is *probably* still steel jacketed, not cored. The steel jacket stuff has a copper wash applied to it so just glancing at it, it will look like a copper jacket, but that's just a method of rust prevention. It's the same reason that the steel cased stuff is all lacquered up.
Actually the stuff does have a steel core, as a matter of fact if you shoot into anything hard the bullet will un-jacket and you can pick up the steel core and the copper cladding. It's actually pretty cool. A lot of the ex-soviet military surplus is steel cored. Here is the round: http://7.62x54r.net/MosinID/MosinAmmo020.htm.
That being said, they do in fact make steel core bullets, but they're more expensive, not cheaper (steel is cheaper than copper but costs more than lead). They're made specifically for armor piercing purposes (talking about armored equipment - a standard.30 cal FMJ rifle round will punch through body armor with no problem at all). I actually have some 163gr.30 cal steel core bullets out on my loading bench. They are military surplus stuff that I picked up at a surplus sale. I've not actually loaded them up into live rounds as of yet as I have no need to. They also make solid copper bullets (with a slight hollow for expansion) as well. They are premium hunting bullets though, usually costing between $2 and $4 just for the bullet (not in a loaded configuration - you still gotta supply the powder, case, primer, etc, and make the round yourself).
These were surplus if memory serves me they were 500 for just under $90. Only problem is they had corrosive primers so you need to wash the hell out of your gun after shooing it.
They have all sorts of variations though. The accepted norm is brass case, copper jacket, lead core, but I've also seen plastic, steel, and aluminum cases, steel cases, and steel & copper cores, as well as an array of plastic coatings and such. Some pistol rounds (or even slow rifle rounds like the.45-70) might not even have jackets on the bullets - some are just straight poured lead (often with a gas check to prevent excessive fouling of the rifling).
I never liked wadcutters they foul up the barrel too much. I have never seen a plastic case well unless you count shotguns but one of my favorite practice 45acp ammo "CCI blazer" uses the aluminum case, not only is it cheap but it doesn't destroy my lawnmower blades as much as the brass and especially the steel when I lose track of the cases.
If you need proof, pull the bullet and stick a magnet to it;).
You sure that isn't steel cored? I have a case of 500 rounds of 7.62x54r who's bullet will stick to a magnet however it still has a copper cladding, just the core made out of steel. He he that stuff will easily disable a car or truck.
First of all I would like to say that making any sort of embedded device is cool and this is no different. I think the source of a lot of people's snide comments and such toward this is that people were quite underwhelmed with the product. There are two reasons for this. People denote a laptop as some form of a PC so there would be the expectation that this would have similar functionality. Second this is Slashdot, typically projects worthy of being featured on this site typically are especially ingenious, clever or imaginative. Cool or not what this is is a 1st or 2nd year EEng project.
And for the record I have designed many systems based on PIC micros. I even designed my bench top automation system using them and a dallas semi 8052. They are so cheap and have such great tools, every programmer should at least play around with them once.
Don't worry the rest of the tree was use for credit card applications, AOL CD mailers and other fine publications.

If just I want to add a couple of numbers together or edit a document, do I need, or should I have to pay for, the ability to simultaneously have an MPEG movie playing in the background?
I don't know about you but if I want to add numbers together I use a $9 calculator. Granted you cannot edit a document on a calculator but it's quite unlikely you can in 96 bytes of ram.
Nice try yourself. Regardless of what the poster wrote that is not what the terms state. What it states is that if a price changes before the item ships they will contact the buyer. They do not state anywhere they check all of the prices before they ship.
First of all they are 100% in the wrong for not going though the courts to collect. That is what they are there for and they have no right to just take the money.
That said, I think your assessment would be spot on if they were sold by a competent sales person at that amount. The problem I have with you wrote is that a piece of computer software really cannot be considered a agent of the company in itself, which seems to be implied. A piece of software in itself cannot negotiate a price, it can only do what it was programmed. Basically what happened is that due to a technical error a contract was made that both parties didn't agree to, which in most cases would render the contract void.
Just to clarify before anyone goes off on me for leaving it out. Amazon would need to go though a court to get the money. It has no right to collect on it's own so in that they certainly are in the wrong.
I have posted this elsewhere by under the law there is a concept known as unjust enrichment. Basically if someone looses money by an honest mistake there is a legal obligation to return the money. Then again it's the moral thing to do, I don't see why people would get so upset over it.
If it was the US military credibility that was reflected in the value of the US dollar, then right now it would take a thousand bucks to buy you a can of peanut butter. There is no reality in a world where the US would use force to secure the supplies that it currently imports and pays for in dollars. Currently the US military is not even capable of holding together Iraq, a purveyor of a fraction of its oil needs.
Regardless of the accuracy of the military having low credibility (which is shortsighted at best) you are comparing it to a computer game manufacturer with no military. Can it happen? Absolutely the reason it is not happening or have happened is that the US values the cooperation and trade with it's neighbors more then the short term gain of natural resources. Iraq could be fixed in a month if the government suddenly stopped caring about the people of the country and acted with an any means necessary mentality. Seriously how effective could car-bombs be if all of the cities were carpet bombed? The problem is we don't want that blood on our hands, which is a good thing if you ask me.
What makes second life, or any other currency, any different?
Two things,
1. The US has a fricking huge military to back it up. While it's certainly not self sustaining now it really doesn't need to be. But if it ever came to the point where they had to be, leveraging the military it could just take what it needs to become that. Second life on the other hand is largely at the whim of their suppliers. If their power company suddenly decides that they don't want to serve them any more they are SOL and the economy collapses. Disgruntled employee destroy a single database the economy collapses. 2. The US dollar has 70 or so year track record of being accepted regardless of it's age of the money or the owner's citizenship. I really doubt that my money will will still be in Second life the time I played it for 2 months in 2003.

Not sure if this is what he is talking about or how it performs in water but it sounds like Synthetic-Aperture Radar.

What makes you think that? ID cards are virtually always property of the agency that issues them.
Common, the Atari 800 had 4 tone/noise generators not 4 channels of DMA sound. If you are pulling in generated sound into the mix you should also count the 18 channels the YMF262 on the sb16 can generate.
So how is writing papers with no or severely limited research materials going for you?

First of all you cannot be a party to a contract when you are under the influence period. That is why car sales need a notary to verify the sale.
This in particular is a clear case of Unjust Enrichment.
