I very recently bought a Kindle, and I love having access to wikipedia on the device, as well as a built-in dictionary. If I don't know the meaning of a word, now instead of guessing the meaning I will look it up really quick, if it doesn't break my rhythm.
I was reading a book the other day on it, a weapon was mentioned in the book, and I quickly looked it up in Wikipedia to see the image, and then got back to my book with a much better mental image of the scene in question.
Well, with the iTunes update, it updates the iPodDriver.kext kernel extension, QuickTime also gets updated and it requires a reboot because the whole graphical system is dependent on the QuickTime libraries. Now, the reboot after the iPod driver isn't strictly needed, but Apple takes a "play-it-safe" attitude with kernel extensions and requiring a reboot to get all caches and autoloading information updated. Sure, some of Apple's apps are a bit ingrained into the operating system, but they don't do it in any exceedingly strange ways, and there is rhyme and reason for their reboots.
Well, the main problem with using "T1meOut" is it's very easily attacked by a weighted dictionary attack. All dictionary attacks take care of common numerical replacements and capitalization. The next issue is weight of the words. Time and out are rather common words in the english language, and even more common when used together. In the case of a full random password, or a word password with randomness interjected, it'd be a lot less crackable than "T1meOut". A much better password would be something like "t&iM-eoUt3". In that case, the words are still there, you just have to memorize the capitalization and non-word components, which honestly isn't hard, people just think it is.
As a prospective student of UIUC, who also has a good friend attending the school in a CS Ph.d. program, I get a bit giddy inside any time I see the university in the media. I've been to that building when my friend was giving me a mini tour of the facilities, although I didn't go see the supercomputers themselves.
I should have amended that this is granted he is running at the proper resolution. I've seen many improperly calibrated displays that were set at the right resolution that were fuzzy, had vertical or horizontal bands, or all sorts of other artifacts. But this won't work if it is not at the wrong res.
Sounds like you have a case of improper LCD calibration. The auto calibration often will not properly calibrate your display on a normal desktop screen. What you should do is bring up a full screen of alternating black and white pixels and then run the auto calibration. If you do that, you'll have a display just as sharp as DVI. I do this for my gaming machine, since I use the two inputs on my monitor as a poor-man's video switch.:)
There isn't no chance, any display technology can get burn-in. I have, in my various places of work, seen several LCD panels that were displaying an almost static image for years on end get a very distinct burn in. It's just that the burn-in times for LCD and other non-phosphor tech is so long, it's not worth worrying about in most real-world use.
Basically, the most popular way for PDP manufacturers to mask out burn-in is to burn-in all pixels equally. So, basically if the burn-in detection sees that you are likely to have burn-in in one small zone of the screen, it will drive that one zone with less intensity, and the rest of the screen harder to equalize the burn-in rate. This, of course, is less than ideal, as it leads to an overall loss of black level on the display, and driving one zone too hard with a static image will reduce the life of the PDP display overall.
Another option for you can be ISDN or IDSL. IDSL is basically DSL over ISDN lines, and it will give you a slight edge over dialup (in the boonies, 19.2kbps conect rates are not unusual), and should have decent latencey. Frankly, you will not be gaming on a satellite Internet connection.
Unless you know enough about VOIP to setup your own. Remember, you're going to be maintaining this over and above your current job functions. It may or may not be benifical to go with something like Asterisk and going it alone. But, if you do go with a consultant, for the love of God do NOT go with SBC. They setup our Cisco VoIP system, and screwed us by not giving us the discs and key codes to the CallManager or Unity software. They did leave the IPCC software in a corner cube, though.
I'm actually in the process of building an arcade cabinet myself.
My #1 piece of advice: DO NOT SKIMP ON THE MONITOR!!!
All too often I see these decently built machines that have a 17" PC monitor in them. Here's what I reccomend in order of my preference:
1. A Wells Gardner or Betson Imperial multisync VGA arcade monitor (27"). This will run you back about 400-500 bucks. It is, by far, the best decision you can make for your cabinet.
2. A high quality TV. This will run you back about the same as the arcade monitor, so might as well go with that.
3. A 22" or above PC monitor. You can't get a very good 'arcade' display because of how clean these are, but it can be simulated. But these are even more costly than the arcade monitor, so you might as well go with that:)
One thing is carefully think of the order you do things. With mine, I first got a junker machine and got the software up on that. Next comes building the actual cabinet, then buying and wiring up the controls. I'm going to use the junker until I feel like upgrading, which I eventually will.
One final bit of advice, think about your control panel. Do not make it too busy. Mine will be a 2 joysitck and 1 trackball configuration. No spinners, no analog sticks, etc. Those will all be usb add-ons.
Any greasy finger-food gets my vote here. It is really annoying to have a thin film of oil all over your keys, and getting it off can be such a pain in the ass, especially when you never shut down your computers.
To all you reccomending Fedora: Fedora is NOT binary compatable with RHEL. Binaries made for RHEL may not run under Fedora.
I'd reccomend Scientific Linux, maintained by Fermi Lab. They keep it as up-to-date as RHEL is, and they include apt and yum for updating. Install mirrors the RHEL install, and is binary-compatable with RHEL.
If you don't know anything about power electronics, linear and switching supplies, and transformers and rectifiers you won't be able to pull this off. You will need to find all the different specs for power, produce switching supplies for each device, and make sure you provide very clean power. I've been thinking about doing this myself, but never doing it, partly out of lazyness with how much work it will take.
Don't even look at the Adaptec ATA-RAID cards, they are mostly based on the crappy Highpoint chipsets that do pseudo-RAID. What you want is a 3Ware card.
Look to eBay for deals, I managed to get a 3Ware 7820 (I think, it is 8 Channel PATA) for a hundred bucks. Currently I have 2 120G drives attached to it for my main system drives, and I plan on getting 6 more 250-300G drives to build a second array on the device.
The 3Ware cards (mostly, they have one cheap RAID 1 or 0, 2 channel card) support RAID 0, 1, 5, 1+0, JBOD, hot spares, multiple arrays per card, and other enterprise level features. It really does work well.
Quality cabling always will make a difference. Not quite a computer situation, but still similar, my friend was recently hooking up a new DVD player up to his new projector with component video inputs. He first just grabbed the first pair of RCA cables that he could find. The projector kept resyncing with the YPrPb inputs. Despite soomeone else's refusal to accept it, I told him to pull out some video monster cables. Once he did that, it eliminated the resyncing.
Cable quality will affect both digital signals and analog signals alike. A bad quality cable will generate a good share of dropped packets, or corrupted data, causing more resends or less accurate data. Also, take care if crimping your own cables, make sure you untwist wires as little as possible, and break the insulation and sheilding as little as possible.
With that said, don't be like a crazy audiophile (key word here crazy) and spend thousands of dollars just on cabling (I know an audiophile who spent 500 dollars on a 6" cable, when a $25 monster cable has the exact same specs. He claims to hear a difference, but I call b.s. on him.). Spending more means getting better, but only to a point.
Turn off caching. In the configuration, privacy, cache set that to 0, and caching is now disabled. Now, why anyone would claim that Mozilla/Firefox is less secure IE because of their own idocy should be shot.
This doesn't suprise me at all. I used to be a big fan of TSS and some other shows on TechTV, all the way back to when it was ZDTV. But since G4 bought out TTV, it's gone to the crapper. I have seen a few episodes of TSS and it really has become sub-par now. I'm very sad to see them go, but since the XTREME! makeover by G4, the old TTV shows have gotten bad.
He's a bit wrong on this. When you drag an application to the/Applications directory all the system does is copy the contents of that application (a specially structured directory) into its destination. The application, once it's first run will then put any support files in place. These files always end up in either/Library, or more typically ~/Library, and 99 times out of 100 it's just a preferences file.
There has been a fix under warranty repqir for quite some time, but I find it very unbelievable and frustrating that it took them this long to publically announce the problem.
I have a 15" AlBook that suffered from this problem. Trust me, they lost money on mine. I went through 3 different PowerBooks, hoping to get one that didn't have the spots, no luck there.
Then the first time I tried to get the spots repaired, they did not have any screens in stock (even though they told me they were in stock), and I needed the machine for school (it is my only computer that has a physical console). A week later, two missed deadlines, and many angry phone calls (they had botched sending the unit back to me too).
I then sent it in over xmas break, and got it repaired (again there was a small hitch since it got scheduled to be sent to me on a Friday, and I was at work, and there was NO way I was about to leave my $2.6k PB sitting at a shipping deopt).
No further problems with the machine. I see a few faint weak pixels, but I never notice them while using the machine.
Not only that, but take a look at your CPU usage during bulk transfers. On my 1.25GHz PowerBook, I see 25% CPU usage on bulk transfers with USB 2.0 while i see < 5% CPU usage with FireWire. This is on the same drive, same hardware.
Also, I have noticed that transfers take about 25% more time when I use USB over FireWire.
Now, about this little device, I myself, being a heavy FireWire advocate do not see a major use for it. In a flash drive, I want the ability to use it everywhere, and many machines I am around have no FireWire (grr!). Although, I would get one if all the machines I'm exposed to had FireWire.
Hardly. Looking at the whole address space, keep in mind not all of it is usable, it is 128 bits in size. This translates to roughly 3.40e38 unique numbers.
Now, 12 grams of Carbon-12 is one mole, or 6.02e23 atoms. 3.40e38 moles of Carbon-12 is 6.78e12 kilograms.
Now the mass of the earth is 5.97e24 kg, so it's not nearly enough to give every atom in the earth even, but it is quite a lot.
Note - it's been too long since my last Chem or math class, so my numbers may be off. If they are, you can go ahead and correct me.

There's also a PORT option in the udev config file. I use it for my Linux Arcade cabinet to have ports on a hub always be the same game pad number.
