The cisco phones are nice, but the feature you reference is actually called DID (Direct Inward Dial) and is available with almost any digital phone service (CAS/PRI and of course VoIP). Basically it lets the office have a bunch of numbers that will ring into the office's PBX main number, and lets the PBX decide where to route them based on a certain number of digits sent from the actual number dialed, which is why your extension is probably the last few digits of your desk's full number. When you dial out, it will always appear as the main office number. The "plugging it in half way across the country and still dial by extension" part is of course not possible with legacy digital services without a VoIP gateway of some sort, and your configuration probably involvs a VPN for the phone to connect back to your company's lan to place the calls (but yeh, it is neat).

Its called proffesional courtesey. If they immediatly notified the public, there would have been an exploit that many days sooner, before ANY action could be taken to fix it. This is the same as any MS or other exploit. Once a firm knows about it, they notify the software's management to fix it and wait a few days to release the news to the public. That gives the developers time to at least create a patch to prevent any further damage. Is it F-Secure's fault Sony did something stupid in the first place? Are you going to blame Semantic on the next exploit they find, tell microsoft about, and wait a few days before alerting the public? How about the IE bug just moved to cirtical status thats been around for many months, is that to be blamed on Secunia? They knew about it since june and waited until this weekend to escalate it to critical, only after a proof of concept was released.
Its easier to prevent a fire by notifying management to fix the sparking wires than to put one out after notifying a world full of pyros to come dump gasoline on it.
And your living rooms light switches address will be...
Actually... my living room lightswitch address is b6. The bedroom one is b5 and my fishtank is on b4. Thermostat is 192.168.1.145 and security cameras are c2 through c6... not that anyone really cares.
For those that dont get it, yes, those are x10 addresses, all controlled via computer through a pc-x10 interface, except the termostat, which really is an IP thermostat. In my own x10 network, they already have single letter (+number) addresses. The ap that controls the stuff does allow aliases to allow "naming" the devices , but Im too lazy to use it, and the scripts I have dont really care if the name is "LivingRoom" or b6.
I say we just replace the whole restroom with a giant metal grating for a floor. If you gotta go pee or poop, just pick a stall and let it go through the floor. When your done, the flush just rinses off the section of the grid you used through a common drain. No fixtures to clean, and when they do their hourly "cleaning" of the whole room, they just get everyone out and flush the entire thing with bleachy water to kill the smell....
Futuristic with lots of space stuff in it (you know, the whole dark planet, FTL travel to other planets, etc). A Great Sci-Fi movie with excellent scene changes and decent plot (even brief nudity), and even though one of the main characters is Bruce Willis, it still came out great IMHO, it just didnt do well in the theaters (probably due to lack of publicity, I only remember a few commercials for it).
Done it many times, and while it is better the more wasted you are (within ability to still watch, of course), even sober some of the stuff that syncs is almost too creepy to have been unintentional. The first sign of a good sync is that the Directors name fades in just as the screams break through to the music of the first track. Another sync is when she falls off the fence the music picks up pace instantly and changes to a more sinester tune, and probably the most notable are the two scene changes that sync directly with track changes: the bells chime when the old lady/witch comes on screen on her bike, and the track "Money" starts the cashregister sounds as Dorithy opens the door to the full color land of Oz. Other stuff to look for include the background voices in the songs matching on screen conversations, the drum hits matching when the old lady is arguing with her family over the dog, and the thunder/rain drops in the music as the tornado scene approaches as well as the singer's voice as Dorithy is running around/gets knocked out, and the house gets taken up and away. It does work slightly after repeating, though not nearly as well as the first time around.
There are alot of sites out there with theories and more details of the stuff to look for, most of this I picked out before visiting them as its quite obvious if the sync is good. Some even go into more detail such as the names of songs vs whats on screen, such as "Balanced on the biggest wave" playing while Dorithy is walking on the fence, or that Side1 of the original vinyl was exactly as long as the B/W part of the movie, with side2 picking up in the full color land of oz (also with "money" playing as noted above).
The requirement being more from the Vendor/Company that provided it rather than what it actually runs on that a hardware requirement. There is plenty of software out there that will run on solaris or Linux (with the proper modifications) or *nix, but with a stubborn distributor that is unwilling to support or certify anything that is not blessed by sun/HP/SGI whoever. In the case of my company, we have a few apps that are strictly NOT certified on anything other than Solaris (yes, they are certified on x86 solaris 10). Oracle only recently certified its platform for RedHat EL, and ONLY if it is a stock implementation (they have verifier scripts to check, and are currently only at EL3). Our next database farm is Sun v40z's, which if you check, are AMD based boxen (Blades simply are not powerfull enough). We had the option of solaris10 or RedHat EL, we are going RedHat (hopefully 4 will get certified by the time we deploy). If you want, you CAN run stuff certified only for Solaris on linux, but as soon as it breaks, try calling support and they will just laff and say "its not on solaris, thats your problem," and you are by yourself. This is the real world, twisted stuff like this exists that makes no sense for reasons other than corporate politics (ie: $$$). Solaris is dieing off, and I am not pained much to see it go for anything other than historical reasons, I was only stating facts from experience.
Some things REQUIRE solaris to run or for the company/vendor to support. If you have a bladecenter, and have something that requires slolaris, might as well put it on a blade since they are cheaper, take less space, less power, less heat, easier to manage, easier to replace/repair/etc...... The company I work for has several blade centers deployed, and several applications that require solaris for support to even consider talking to you. Now that sun supports the IBM hardware, we can use a blade instead of a full 1+u server per app. Most of everything else we use runs Linux, which works very well on the blades already.
But if there is only one (is there more?) Internet backbone
There are several "backbone" networks. The tier 1 orgs mentioned in the submission (Level3 and Cogent) are just 2 of them. Each has a network that spans a large geographic region and peers with many smaller networks and other tier 1 networks. This network of networks is the collective internet backbone. One could go away completely, and a good bit of the internet would still be around, just the customers on only 1 upstream provider would be on a network to nowhere, and would be unavailable to the world until their ISP got a link to a different tier 1. Though Level3 is playing like a monopoly, they are not, and got reminded of that with the result of their Cogent dispute.
Companies shouldn't waste time/money developing a solution for a problem from the ground up where adaquate solutions already exist. It will cost less and waste alot less time (and since time=$$...) to simply buy a storage solution thats been around, been tested, already has tools and utilities built specifically for it to monitor/configure/report/etc, and since they are being mass produced can actually be cheaper than just the hardware for your custom system. Not to mention that there will be support for it outside your company. I would rather spend a little more now to have a solution than spend several months developing something to save a minimal ammount of money. Unless you plan on marketing the solution itself, there is no need great enough to justify developing it from scratch.
<shamelessplug>
As a customer, the 3par solution has been very impressive to me and the company I work for. We have EMC arrays, Netapps, etc, but the 3par blows them all away in performance/size/just about every aspect including price, and we are currently migrating as much as we can off the other solutions onto the 3par. To make it more flexable (the unit itself is designed for fiberchannel), we got a set of onStor NAS gateways, and they make NFS actually faster than local disk (using Gig-e). The 3par is highly modular, and the software to use it makes it simple to reconfigure the volumes/raid type/whatever. It also does snapshots for you.

Your post is rather trollish, but Ill byte anyway. Unless you are sending UCE (unsolicited commercial email), the laws dont affect you, hence the "The law also forbids spammers..." qualifier. This guy is well know for sending many UCEs in direct violation of the Can-Spam act: using phony return: and from: headers, not including a notice that the email is Commercial in nature, using Subject:'s to make the email look legit to trick people into opening them, having "unsubscribe" links that do not do anything or just sign you up for more spam lists (if the link is even there), etc. He is/was making money by sending these emails, and knowingly violating the law. Sending emails from multiple domains by itself is perfectly fine, I do it myself. The FBI doesnt care about you, unless you have many people sending them complaints about spam emails coming from you. There was a specific well defined reason they siezed his stuff. Not to mention this is by far not the first time he has been in trouble for spamming.
I dont know how accurate that is... Back when I was part of a college Solar Rayce (now Formula Sun) team, suspension design was an important part of the design, and that was in '99. Granted, the design used was very primitave (single pivot arm with coil-over shock attached at the axel for the rear, similar design for the front), but it was realized even then that the vibrations from the road would not only cause efficience losses, but would greatly increase the risk of breaking stuff. With the batteries, motors, power conversion units, solar array and driver, these cars are still pretty heavy, and trying to drive one without suspension would surely cause problems.
As mentioned in another reply, the type I reffer to have model/serial numbers that begin with SPI, and have the blue oval SPI logo on them as seen on the company's website. Given the computer industry's willing ness to blatently rip-off other products with cheaply made imitations, it would not supprize me if there were in fact a cheap sparkle knock off. They could even spell their name different, sparkel vs sparkle, or attempt to cause confusion by calling that model or line their "Sparkle" model by acme corp. OR, SPI could actually make a cheapo version strictly for bulk sales to case manufacturers.
My general rule is never trust the PS that comes with the case. Assume its crap since it usually is, and replace it with something you know is better. The shop I worked at sold both HEC and SPI as their "good" brand depending on which was available from the distributor. The white-box cases that were sold with PSU's had a high frequency of return for PSU change cause it blew up after a week. The cheaper "$19 special" PSUs were the ones we stripped out of the cases to sell bare-bones cases. There is a reason the $19 specials were sold with no warrantee.... but both SPI and HEC have warrantees on theirs.
And yet they make doctors go to school for twice as long, so engineers who need to be just as knowledgable and well-trained have to cram it into four years. Ah well.
Most (good) engineering schools take a bit longer than 4 years. Ga Tech (where I happened to go for Mech. E) generally takes 5 years, and thats only for undergrad. The engineers in charge of engineering stuff that has potential to kill people/destroy stuff are usually required by law to get a PE (Professional Engineer) certification. To get that, you have to first get an EIT (Engineer In Training) certification by passing the FE (Fundamentals of Engineering) test, and getting some work experience under another PE, just as medical students are required to do their residency under supervision of other doctors before becoming doctors. Going through this process can easily take as long or longer than finishing med school.
The difference being alot of jobs are available for engineers that do not go through all (or any) of the above steps. Simply obtaining a BS is good enough for alot of jobs, they just do not have as high a pay rate, nor the serious consequences for screwing something up. Its generally suggested to get EIT and at least a masters degree to get a successfull job of the type most people go to engineering school to get. It takes 6-7 years of engineering school (not taking summers or overloading your schedule...and passing everything the first time around), which most people (like myself) are burned out from after the first round. For now Im stuck in a lower paying job, doing mostly non-engineering type work (of the mechanical type, at least), waiting and telling myself Ill continue on and get a real engineering job soon...
Whats your avg. latency on a normal pots phone? Barely noticable. Same on VoIP (unless you are attempting it over dialup to a far away country). Avg satelite latency? Very noticable, ever watch the news when they have a correspondant "Live via Satelite"? The local anchor asks a question and then you sit through a few seconds of silence while the question goes across satelite to the correspondant, and a few more while the answer comes back. Satelite phones have the same issues, though maybe not as severe. Satelite broadband has the issue as well, though the uploads go through your dialup connection (in most setups). Not to mention the cost associated with taking up time on a sat link...
Quality usually goes hand in hand with price. The best ones are usually the most expensive (PC Power and Cooling)....
Not always, and not what I buy. ALOT of powersupplies these days are way overpriced. They focus more on inflated power ratings on the cover and bling like LED fans and chrome gratings (who is even going to see that, the fan usualy is in the back??). A better way to determine quality is weight comparison. The ones that work better generally weigh more as they actually use real components rather than single-chip regulators. The brands I have stuck with are Sparkle and HEC, two brands that are rebranded by several other companies after inflating the price for their company's logo or the bling they add to it. 3 HEC's to replace cheapo came-with-the-case PS's, and all three are still running strong, several years longer than the ones they replaced. Best part is, they dont cost that much. Most reviews that include them (no I didnt rtfa on this one) take note of it, and they usualy wind up near or at the top, depending on how the test was done.
You're stupid. Centripetal acceleration is towards the center of the circle. It's the acceleration of the changing direction of the velocity vector (which keeps turning towards the center).
...
The centripetal acceleration that keeps us on Earth is due to gravity.
First off, calling someone stupid just makes you look like a troll. Who modded you "informative" (perhaps yourself since posted as AC)?
Anyway, centripital force AND centrifugal force BOTH keep it up and in place. If you had one without the other, the thing would either launch out into space or fall straight back to earth.
The centrifugal "force" is the result of the delta V you get by traveling in a circle. The force itself is actually the sum of the forces you get when you translate your radial velocity into cartesian accelerations (basically what you said, changing velocity vector, etc). However, the centripital force is the force along the string/space elevator that is opposing that centrifugal force, in effect keeping the other end from flying away.
If the centripital force was only from gravity, the elevator concept would simply not work, as you could only ever have an anchor point in geostationary orbit, any further out and the counterweight would simply fly away, or you would have an end point on earth dragging the ground since it would be going slower than earth's rotation.
Well, seeing as Firefox/Mozilla has not even been around that long....Anyway, of the 8014 "open" bugs listed on bugzilla (up to ID 309326), the oldest is ID 127244, dating to 2/22/2002, and already has patches in place, though it still shows up in some versions. And.. this is just a bug relating to a menu not functioning properly, not a 'vulnerability".
