nyquist's theory only proves true if your waveform is a sine (or other regular) wave. For example:
A 10kHz waveform sampled at 20kHz would be one single point at the peak of one wave and the trough of another. What happens when you go to put it back together? Well, basically you just get a smoothed line from one point to another.
What if your waveform had a peak that (for example) was sustained and then suddenly dropped to the trough? Well , all you'd get out the other end would be the same line from the peak to trough as you did before. (Purists will note that that wave will be a mish-mash of frequencies higher than that of the "base" frequency... but go with me here.)
So, when 44kHz sampling is used, you have to remember that at 22kHz, all you're getting is a very rough approximation of what went in. And even at 11kHz, all you're getting is 4 points per full cycle of your waveform.
This is also something to remember when using digital scopes at the extremes of their sampling rates - the waveform you see might not be the waveform that's actually there.
Perhaps I should have just put "Generic Image Application A" and "Generic Image Application B" in there. I've had a lot more sucess in the windows world with it's clipboard and random applications-at-large than I've ever had with X.
... then the players coming in from overseas would have to be modified for sale in the US market
DVD player margins are so tight, no-ones going to change any firmware/hardware specially for the US. They'll be the same as all the rest of the players they sell to all the other regions of the world.
For the US they'll be "Modified" to have the hidden factory menu setting to obey the flag turned on. Something that the average user will be able to change by entering an easily-googled "sekrit" code. Just like every single asian DVD manfacturer already has for region coding.
This would be the cheapest way to do things, and if you're a struggling asian no-name manufacturer , you want it to be cheap.
I think he was working on the principle that only the 4:3 section would be burnt in (out?).
The sections on the side, when they were used for 16:9 content, would look brighter,whiter and have a hint of minty freshness to boot, compared to the drab, 4000hr old 4:3 section of the Teev.
"Normally" you have a meter that gives you the total kW/hr reading, metered at some discount rate. You then also have a "surge" meter that reads peak usage, or usage above a stated kW/hr. This is normally used in industrial estates to (help) discourage Big Power Users from switching everything on at once. This way the electrical company can use equipment with a lower surge capacity.
This used to be a real problem at a lab I used to work at, as they had a number of large (20kW) sample drying ovens. Coupled with the "small" (5kW) furnaces we had in the lab + A/C + freezer storage etc, it was quite easy for all the switched loads to "sync up" and.... ooops! $4,000 for a single 5 second 200kW peak surge this month.
There was a power meter gadget on the main incomer with a serial interface left from the previous tenants, and after much cursing in Perl, I eventally linked it to the server in the lab to turn on a light when we were nearing our "peak meter threshold" (100kW). The lab staff would then hold off putting new samples on, or would switch off a few idle furnaces.
As the average lab load was about 75kW, this saved us many thousands over a year.
I used to hack webplayers, and there was this one guy who got the PCI and Mini-PCI pinouts, and got soldering, with little jumper wires between Mini-PCI slot and PCI card. Although it *looked* like a dog's breakfast, it rather amazingly did seem to (almost!!) work. There were details of it on the net once... aha, bless you archive.org, here it is
But surely *someone* sells the proper mini-pci-to-PCI-via-a-ribbon-cable type adaptor?
It's probably easier to just go buy a cheap-o desktop PC and an inverter to suit.
This is still pretty much a straight up and down operation. Perhaps with a bigger/longer burning engine, you could reach the height of the ISS, but it would whiz by at 7000km/hr. Bit hard to dock with at that speed:-)
Imagine - you can't establish radio contact with anyone for 4 years due to BPL. Your HAM radio days are pretty much over. Suddenly, a disaster strikes in your area. Are you still going to have all that equipment that's been lying around useless in your basement for 4 years, or would you have sold it all off to other enthusiasts?
The cameras used on the rovers have wide sensitivity to the whole visible light spectrum + more than just a bit on each side. Greyscale cameras are more useful when doing science. You plunk a variety of filters over it (I think they have 9?) and you can 'see' from UV down to infra-red.
"Simple" Red+Green+Blue cameras are a poor equivalent in comparison. For example, different minerals are clearly visible at certain wavelengths. Your "standard" colour camera will have a hard time picking out a mineral if it reflects light somewhere between red and green, where a specific filter on the greyscale camera can highlight it without trouble. To drastically simplify a whole heap-o-science, imagine a colour camera with Red+Green+Blue PLUS IR+Yellow+UV+Orange+Purple+Pink sensors. That's what's on the rovers.
Hell, make it *before* you pay the kids college bills.
"I'd really like to make a payment this month, but it appears the majority of civilisation has been demolished. Let's say we wipe the slate clean, eh?"
It's either a typo , actually referring to 100% humdity (crikey!) or they mean the wet bulb temperature was nearly 100 degrees.
For those who say "WTF is wet bulb temp?" it goes like this:
You have two thermometers. One has (typically) a sock/tube of cloth over it's sensing bulb that has the bottom of the tube in a bit of water, so that it's wet. It's the "wet bulb"
You also have a dry bulb. (i.e. a normal thermometer hanging out in the air)
Now, at 100% humidity, the wet bulb will be at the same temperature as the dry bulb, as the water on the wet bulb does not evaporate (as the air is already saturated). As the humidity decreases towards zero percent, the wet bulb will have a progressively lower temperature compared to the dry bulb, due to the cooling effect of the evaporating water. Look the two (wet and dry) temperatures up in a handy chart that someone has already calculated, and ta-da! Humidity in percent.
It's not a bug, it's a feature , to stop the page-widening trolls:-)
Now a handy slashdot feature to have would be an auto-html-link-maker, seeing as people seem incapable of typing <a href="http://your.site.com">site</a>
If I forget my passphrase, no matter how pissed the cops ge, it doesn't really make a difference.
There's this thing called 'contempt of court'.
Prosecutor : "Well, would you please tell us the passphrase to your files." You: "I forgot it (grin)." Prosecutor : "But our surveillance shows you opened that file yesterday, and 5 times last week. And yet, you forget?" Magistrate : "Defendant, it is obvious that you know your passphrase. Please reveal your passphrase to the court." You : "I forget (grin)." Magistrate : "Very well. Three months in jail for contempt of court. This session will resume at a later date."

no way to differentially update content or inform the user of updates Heard of HTTP code 304 - Not Modified? Servers and browsers already know how to use it, and they do it transparently to the user. And maybe you should consider putting a "last modified" timestamp on your web page, to help stop clueless/hopeful people from overriding their browser and downloading something they arleady have.
HTTP has it's faults, but none of the problems you mention can be seriously blamed on HTTP.
That's true - I believe you risk not being taken seriously if you go with the caps and the exclamation marks.
Hyperbole is unwanted if you're trying to be serious about an issue. Even if you just reply with simply, "No. If you turn it up to eleven, you'll overheat the motors and it might explode.". It sounds a lot more factual and the recipient is much more likely to take your advice seriously.
\document and settings\local settings\application data\microsoft\outlook Now read this post again and pay attention to the path. not an ms fan boy, i just dont think its that hard.
Dumbass. Checked your folder settings lately?
Your bitchy little reply would have had some merit , except that "local settings" and "application data" are hidden folders. By default, n00bs don't have them visible, what with them being set being hidden and all. That what I meant about being "non-obvious". And yes, the files and settings wizard works ok, but it doesn't help you when your.idx files get hopelessly b0rked and you need to delete them.
More like ignorant clod, seeing that the only people in Europe whose official language is english is, well, the english. And there's always debate about whether they're "european" anyway:-)
Then you've got the french, germans, polish, swiss, italians... and a bunch of other countries north of the mediterranean that I loosely group as "European". Seeing that I live on a continent as far away as you can get on the other side of the world, that's good enough for me:-)
But seriously - widen your worldview, just a little bit. Try to realise that not everyone has such an excellent grasp of the english language as you, and it may well be their second (or third) language.
Or I dunno, maybe he's a brit with crap typing skills.... it *is* a little hard to tell.
