The extension works almost the exact same as opera's built in gestures. Its almost like an opera user designed it (I used opera until I found the extension). The only differences I have noted so far, is that to use the button chords to go fwd or back a page, in opera you could hold one button down and click the other several times to jump several pages, while in the FF extension, you have to let off both buttons and do the entire chord over again for each page. Also, closing FF using the close gesture causes a crash almost every time. The extension also has the capability of adding new gestures, linking them to bookmarks, etc.
Can't imagine this is more efficient than air cooling. Oil is far denser than air and the cooling comes from air cycling through the components and carrying the heat away. I wouldnt expect oil convection cooling to be terribly effective...
Its that density that has alot to do with it: more mass for it to offload the heat into per area vs. the air. Even if the fans were left off, oil is a much more effecient conductor of heat than air. To get straight to the point, the thermal conductivity (ie: how well it conducts heat) of air is 0.024Watts per Meter*degree Kelvin, vs that of Oil (machine oil in this case, but mineral will be on the same order of magnitude) at 0.15W/MK. Water would be better if it didn't tend to let the electrons go wherever they wanted, its conductivity is 0.58. The area of hot surfaces on the computer that are exposed is the same, since this is total emersion, and so long as the oil is moving enough to distribute the heat, the ammount of oil in the container is enough to serve as a decent heat sink, and the large surface areas of the top of the oil and sides of the aquarium would be sufficient for distributing that heat for the air to convect away.
How much heat this would work for would require thermo equations on the surface area of the exposed tank surfaces using convection (q=hA(dt)). h is the thermal transfer coefficient, and depends on velocity, density, geometry, flow pattern and a few other things, and since Im lazy Ill leave that as an exercize to the reader. Once you find h though (and for a flat plate like the aquarium walls and oil/air surface is, it should be easy), calculating the saturation point is simple.
As this site points out (didnt/. post this too?), Monster Cable went on a spree of suing anything that had "Monster" in its name, including the Monsters Inc movie, all the Discovery channel Monster shows, and the Vintage consignment clothing store linked above: Monster Vintage. To get an idea of how rediculous this is, here is a list of all trials involving Monster Cable. As you can see, they are quite litigation happy, and are still filing away. I have always thought their cables were overpriced lampcord, but this just gave me more reason not to buy their outragously priced copper.
Has been in a battle over this same subject for quite some time now. Most recently about Informative stickers the schoolboard put in all Science books that contained anything about evolution ruled unconstitutional by a federal court judge. Google returns many articles on the on-going debate/lawsuits that have been brought on this subject. Its quite amusing, given that Cobb is the ultra-conservative (somewhat wealthy) county around the north-west corner of the moderately liberal Atlanta (at least for Georgia, look at last year's election results for an idea), stuck in the middle of the bible belt.
The key I think is the "Open source DB market." Last I looked Oracle was far from open source, same as MSSQL and many others. Sure, they have 40% of the Open Source market, but not all potential DB customers use Open Source solutions. Say 10000000 DB's are out there, maybe only 20% are open source, 40% of which use MySql. Thats only 80000 DB's, 10x which is only 800000....
Part of being intelligent is realizing you don't undersand everything.
You are either trying to be funny (and failing), or you should take some of your own advice. The laws of thermodynamics and conservation of energy still apply. You cant get more out than you put in. Basically, the power that you use to chage a battery is the ONLY power that goes into it. "Boosting" as you call it does not affect Power, it meerly converts the power. Computer power supplies take in standard wall outlet voltages (110V, AC) and convert them to lower voltages with higher currents (+-5 and +-12 V, DC) and DC instead of AC. Power inverters do the opposite, they take in the 12V supply and spit out 120V AC at lower currents. Power = V*I (Voltage * Current), Ohm's law. High end power converters allow more devices, and higher drain devices to run off them because they have larger capacity components designed to work with the larger power requirements. They still require a source supply large enough to generate the total power required. Smaller inverters not designed to handle that kind of load would burn up or melt from the heat generated simply by the resistance losses of its internal components. The same reasons apply as to why you cant start a car off of 2 9v batteries hooked together, sure its 18V, but they have nowhere near enough current to even turn the starter.
Neither is connecting to the POTS network. Vonage has to pay to connect to with other carriers so their service will actually go to non-VoIP phones. They could simply pay for and get a few E911 trunks along with their POTS gateway trunks, but thats not the issue. The issue is where that 911 call would end up. My guess is Vonage only has a few POPs on the POTS network around the US where they have gateways. These would be the only place to route E911 traffic, and would therefore route to that CO's designated 911 switchboard. To re-route the 911 call to a switchboard closer to the caller, Vonage would have to get the 911 network to re-route the call internally, something that the network isnt really designed to do, and might not be able to do at all if the caller is far enough away. This is not (for the most part) a problem of Vonage being lazy or uncooporative, its just technically very difficult to do with phonecalls that could originate anywhere.
Cell Phone company knows where cell tower is, they route you to 911. Vonage knows where you are, they route you to 911.
Yes, they could route you onto 911, wherever their trunking gateway sits, but WTF would a 911 operator in Seattle Wa. be able to do for you if you were being eaten by sharks in Miami Fl? The problem is that VoIP only enters the POTS network where they have trunking gateways, which could be anywhere. E911 systems use dedicated trunk lines to route to the call centers to ensure availability and speed. To setup a proper working E911 system they would have to setup gateways all over the place to route to the nearest 911 center, and then have you pick the one closest to you, so that when you dial 911, it routes directly to it rather than across the US. Cell phones are the same, your 911 call goes to the nearest 911 call center the Tower terminates to network wise. This could be(and in many cases is) farther away than the one a POTS line would call (I have dialed 911 in downtown atlanta, and got an operator in Decatur).
I know the land attack is old, but still, linking to a.c ? Why not link to the description of the attack and let that be enough. I was not aware/. was a scriptkiddie toolz warehouse. As stated by the article, there are still probably a bunch of machines this will affect, and putting a link directly to LAND.c on the main page probably isnt such a good idea. Whats next, root kits?
Kinda like what Endless Pursuit has done? You upload you waypoints/tracks, it overlays them on a topo you view from your browser. Dont think it needs any plugins, as the overlay is done by the server and is output as a normal image.
I once had an idea of doing this, and might eventually get around to finishing it. I just dont have the map library to do the overlay. All I could do is draw the tracks. Image librarys (like gd) make drawing the tracks easy, and overlaying just as simple. Getting a library of map images that would allow you to use it for this sort of thing would be the hard part.

Actually a friend of mine works their tech support for their silver plans. She also knows bronze and gold techs, and she as well as them are in the Austin area.
Sounds like the first step to teraforming mars, as the red Mars trillogy depicted. Add gas to the atmosphere to thicken it, which retains more heat, which sublimes the polar dry ice/water ice caps, which adds more gas to the atmosphere.... Of couse, they speed it up by burning up large water asteroids in the atmosphere too, and digging large "moholes" down to where geothermic activity heats the air, and introducing modified algaes and liches etc...
The 96 olympics used credentials with 2d barcodes for all volunteers/participants, and a HID like credential card with a bio-scan to get into the village. UGA uses similar tech to get into their dorms. Instead of the easily spoofable finger print, they use a bone structure scan. You place your hand on a plate with fingers against posts to assure correct alignment, and it compares your hand's bone structure to its records. Slightly harder to spoof, since most people dont leave their hands laying around, and generally just as quick and painless. The only drawback would be cost, as Im sure it costs a good bit more to scan bones than fingerprints.
Yes, as has been posted in other replies to your post... but I feel that for metric time to be of any use scientifically, it should be based off of the current Second, rather than 10Metric Hours/Day. That way, all of the other metric units based on seconds would still hold with metric time, no conversions or new unit deffinitions necessary. Also, I think this would be much more relavent in a space travel or submarine setting, where the unit of "Day" is basically meaningless since there is no sun rise/sun set.
Minutes of 100 metric seconds would be 2/3 longer than current ones, allowing more excuses to be made for being late to work/meetings: "I meant I would be there in 10 metric minutes", hours of 10000 seconds would be about 3x longer, and a typical earth day would be about 8.6 metric hours long. While not very usable while on the planet, in space travel you could expand that to 10 metric hours per "day" (27.8 normal hours).
Essentially all of the electricity being fed into the CPU is directly converted into heat.
You do expect output from your cpu dont you? Sure, the energy CONSUMED by the CPU is transformed into heat, but remember that electricity flows THROUGH the CPU. The CPU alters how it goes through, otherwise you might as well stick a bank of resistors on the end of a power cord and call it a computer. Those "patterns of information computed by the CPU" have to go somewhere after all. Subtract the output power from the input and supply power, and whats left (ignoring the small ammount that might be radiated as energy other than heat) turns to heat.
Hmmm, I do not quite understand the preoccupation that the US needs to be numero uno in everything.
Well, someone has to be "numero uno", or nothing will advance. If every country settled for being numbero dos, where would the innovation and advancement come from? Striving to be the best pushes technology forward, it gives people something to work towards. Sure, the US might be a little arrogant about it (ok, alot), but it gives the average citizen something to be patriotic about, which in turn makes them more supportive of advancing said technology to stay on top, which makes it easier to get funding from politicians looking for votes. If another country wants to take the lead, bring it on, it will fuel the race and push technology ahead faster than ever.
Yeh!! and then once you have that VoIP modem line up, setup two more, since that new bandwidth can handle more lines. Then do the same over them, dial in with line-sharing multilink ppp protocol to another VoIP provider, and do it again! You should have a DS3 worth of bandwidth pumping through that already over-shared T1 in no time!!
Carrying crowbars, knives, screwdrivers is an offense.
Yes, but does that mean everyone that carries one is a criminal that is out to rob someone? Should they therefore be made illeage to own/make/sell? RIAA would say yes, no matter what the true intent is...
Because you no longer have to physically move lines when you do move, adds, changes, there is no need to run new lines to new locations, and there is no need to add it to new sites.
Im not sure exactly what you mean by physically moving lines/running new lines. If theres no cable run you have to run one if you want any kind of network/phone service other than wireless. Aside from that, the whole idea of PBX is that you program the PBX to route calls going into it to go out on different lines, no need to physically re-punch terminations to move the line. If you want to move from desk A to desk B and keep your phone number the same, you simply update the PBX's configuration. What you might be getting at is VoIP PBX/Phone systems are more user-friendly and can be updated easier by the user since it uses more familiar IP routing (simply keep your IP, and as long as you are on the same lan segment, nothing has to be done). The fact is, newer computer-based PBX's can have easy to use interfaces that dont require a "Certified phone tech" type to re-configure. The system we uses here, while not VoIP, allows you to route your phone to any other phone in the office simply by pressing a feature code, entering your extension and voicemail password. It makes cubicle moves easy.
The fact of the matter is that you lose voice service if your T1 goes down if the interfacing device is an NBX or a classic PBX, or do you put both voice and data through a single T1, that seems kind of stupid.
Same as you lose voice service if a bell-tech decides to play in the nearest remote terminal cabinet and cross-connect someone else's line on top of yours, or short it, or a tree falls on the line. And guess what, if your POTs line is down, so is your DSL (it uses the same pair).
Yes, I am slightly biased, as the company I work for does exactly what you just called "stupid". We sell a T1 to buisnesses, and using VoIP, deliver both voice and data across it in a shared manner. The router at the end can act as a gateway if the company is not using a pure VoIP pbx. Any bandwidth not used for voice is free to use for internet access. If you dont want to lose service due to 1 T1 dropping, get a second or third T1, the cisco routers we use can handle Multilinking them so that if one drops, everything keeps going, just at a lower bandwidth.
I have a '90 nissan Sentra that was manufactured without it as well. No power steering reservoir, no pump, no power assisted steering. The only power-anything in the car was the brake assist (yes, it was a manual). Car still runs, though its on engine #2, CV joint set #3, and probably near the end of life of the 2nd brake rotor set. All this at about 160K. Engine was replaced cause it was cheaper than changing the timing chain (since I had a friend that did it at cost of the replacement junked engine).
