Note that it is not free data capacity for existing radio stations either.
Filling up the frequency gaps with data up to the treshold of hearing (which would be utilizing psychoacoustic modeling to open a data channel) would increase the total power output of the FM transmitter for the same strength of the audible part. Hence, an FM transmitter of a particular maximum power output would have a smaller range when they start using this. Since increasing the transmission power of a radio station often is often not financially or legally an option, stations will only do this if this data more than compensates for the smaller coverage area.
For embedding artist and recording information, there already has been RDS for almost a decade now, which has more than enough bandwidth for that.
The idea behind the lossy audio codecs such as mp3, ogg, etc, is, is to allow a quantization noise spectrum at exactly the (frequency-dependent) threshold of hearing, which changes depending on the active sounds.
Any inaudible 'hidden' data will also have to be below that same threshold, otherwise it would be heard.
Hence, if the audio codec doesn't remove the hidden message, then it's not optimal or you're encoding at a too high bitrate.
See title... It depends on the situation and the tool. And you dont really know unless you buy, install, deploy, and execute both options.
In your example, the commercial support would still require capacity from your IT staff. Even if it were just for explaining what is wrong and convincing that it is their fault and not yours or somebody elses and telling them to fix it. Commercial support does not mean zero effort on your side.
Cost calculations can be done in many different ways (economics 101). Each of them is wrong, but some more than others. That is why determining the cheapest way to do things is very hard.
There are other things at stake too: what if the company folds or sunsets the product? What if the support is not what they promised? What if they blame your urgent problem on you or a third party? What if they say they can't find the solution and want to give you a refund of that steeply discounted support contract?
With open source, there are ways out for each of those situations. With closed source sometimes too, but not always and often they are very costly.
In the end, not only cashflow but also features, reliability and availability are often 'veto'-level factors for deciding between different options anyway. That is independent from which product is open source or not. Whether or not it is open source can only influence those factors, but in itself is not a deciding factor. Weigh the factors and decide never choose blindly or say things like 'open source is more expensive in the long run' or the contra, because it depends...
True, but I doubt that is their intention. They have nothing to gain with that except people moving their business elsewhere. Disabling use of voip for their own residents however effectively keeps the voice telecommunications competition away, protecting the national telephone company (~ies?)
You're not alone, happened to me with the same board for the Athlon. I had two, in a server and its backup (doh!)... they failed within a day of each other (doh! again! suffice to say that now they are different brands and types). Warranty from abit returned me two fixed board (new caps), but the caps blowing also fried one of the CPUs. Now those boards are 'spare trash' boards, and abit is not on the buying list until they publicly demonstrate that the caps problem is forever fixed.
And I knew one person who was using the same boards, and had the same problem, with each of them...
- Comes bundled free with the purchase of an overpriced other product. Only free if you have a valid license for that other product. - Will begin charging for it as soon as you're hooked. The first shot is always free. - Every time you use it, it gives you a popup that it cannot display the content until it first downloads an installs a software upgrade. - then tries to sell you stuff before it shows you the document. - Only gives good results when generating docs originally created using other ms products. In all other cases, it screws up the formatting. So does changing the video or printer driver, or mouse by the way.
You're forgetting multiplatform support. PDF is available on anything from windows to linux, mac, and even palm devices. I have the feeling that whatever MS makes will not be as pervasive...
Sure, they could, but that would probably be outside the intent of the law, because none of that traffic will have endpoints in their country, its all transit (if it were not transit, then there would have been TCP/IP packet decoding already).
That's only a problem of there is any TCP/IP-level processing (routing, switching) going on on those undersea cables. I suspect it is probably some sort of WAN framing (ATM, HDLC, etc) what they use on the undersea cables, with TCP/IP just layered on top of that (for those bandwidth customers that want that). So then the 'switching stations' in panama, if any, only need to do the lower level frame processing and never decode the TCP/IP packets or headers, or even know or care about it.
Most current diesel trains actually use the diesel engine only as a generator for electricity for an electric engine....
All you need is a little energy buffer to allow for the reaction time of the stirling engine to changes in energy demand. Sounds more like a job for a big capacitor than a battery to me.
Wow I wish Sony used those batteries on the Vaio laptop instead of the onse that broke in mine after less than 50 cycles, of which not more than two dozen deep cycles.
Similar experience with everything else that I owned that had a rechargeable battery (UPS, cell phone, etc).
Batteries ususally are just not that good yet. I have big hopes for bidirectional fuel cells. Warranty can fix a lot of my worries though, if it explicitly includes the battery.
Last month I saw a documentary that claimed that when vegetable oils are to be used to power automobiles in the US, there would be far from enough surface area in the US to grow that much crop. Being more densely populated, I'm sure in Europe the same is true.
The same documentary mentioned that the strong winds in only one particular of the windy midwest US states, when fully harvested with wind turbines all across the state, would be enough to supply the _entire_ US electricity consumption.
So what we need is improved energy storage technologies to compensate for the unpredictable nature of the wind, and we're set. Enter fuel cells and the hydrogen economy.
And some people used to think the 'new economy' was started with the Internet. Uch, was that a mistake, on two fronts.
In Europe gasoline octane numbers start at 95 for regular gas. In the US, the regular gasoline which most cars use is 87 octane, even the maximum octane 'premium' gas for the sports cars is only 93 octane. Cars in Europe have much higher octane gas to run on, hence can use a higher compression ratio and hence squeeze more power out of smaller, lighter, more efficient engines.
So all that is needed for that climb is a four cylinder generating 150hp revving at 6kprm, generating electricity for an electric motor capable of putting that power on four wheels (assuming some loss).
Plus when this guy is going back down on the other side of the mountain, he basically gets part of his spent gasoline back by the recharging during braking.
You're not always driving on that 30-mile section, so a 380HP engine with a hybrid that runs in hybrid mode everywhere else would still give you a car with a better gas mileage, just not on that one slope.
At 30mph, your engine RPM probably is much too low for the engine to reach its peak power and torque, so you probably are not even close to using 380HP during that climb. With a hybrid, you could have your engine revving at peak power, where the efficiency is much higher, to generate electricity for the electric motors, which could very well result in a a lower gasoline usage even on that slope, going that speed with the same load.
And, starting 2010 there will probably be a fuell cell instead of the battery and that may just be able to store enough power for that 30 mile climb.
Per mile, maybe, but why aren't you also complaining about people who drive a lot? The "MP" in "MPG" is "miles per", you know?
And uh, looking at the facts, a lot of sedans have the same or worst mpg as most SUVs... And how are such sedand and vans/minivans an 'ilk' of an SUV? Or do you think those are not gas guzzlers?
If you're so worried about polution, then why not complain about people who have kids too? Talk about polution and hidden cost... It's a free country you know, if people want to drive a particular car, then they have the full right to do so. Just like there it is somebody's personal choice to drive a long commute every day instead of moving closer to work.
I'm all for hybdrids and other better efficiency fuel technologies, but dont tell me what to drive.
"Look at what they pay in Europe for gas: close to three times the price, most of that taxes earmarked for things like improving public transit, cleaning up the environment, etc.."
In most European countries the huge income from those gasoline taxes go partly into road construction, and mainly into the general big pot of cash with a surprisingly small proportion for real environmental cleanup or public transportation. There have been multiple studies that show that the price of gasoline has no influence on amount of kilometers that people will drive every day. It's mainly just another tax, it has almost nothing to do with getting money to improve the public transportation or the environment. If the environment was really a factor, there would have been a tax on kids.
fuel cells... "and they made it quite clear the technology isn't quite there yet."
But in the article, Toyota expects to be mass-producing fuel cells by 2010. Maybe they mean initially as a replacement of the battery in a hybrid.
I do drive an SUV, am not an environmentalist but still would buy a hybrid if it has V6-level torque and is not much more expensive (comes with a good stereo, sunroof, etcetera etcetera). Especially if the hybrid engine is more reliable and longer lasting due to the more even load on the block.

Hmm, is that cheaper than the improbability drive? I read about that but it seemed kind of expensive. Can't seem to find a used one.

"but they are talking about a paltry 40/29mpg"
