That really depends. The Dodge with the Cummings diesels are so loud, even at idle, that you have to turn them off in drive throughs to be heard over the squak box. The new Chevy diesels, unmodified with stock exhaust, are pretty quiet. About the same as a 8-cyllinder gas truck. The Ford diesels are somewhere in-between.
The real difference on the street (at least around here) is that people with diesel pickups typically bought them to haul heavy loads. US diesels are terribly tuned down and restricted from the factory, so simply putting bigger diameter exhaust, messing with the waste gate, and changing the engine computer settings takes a 275 HP diesel to 350 or so. For less than $1500 most times, depending on exactly what you do. But that makes them loud. Just like me 8-cyl gas pickup. I tow an RV with it, so doing the exhaust make a huge difference in its power output, but its also louder.
I feel for you....I live on the corner of two streets with a 4-way stop in a rural area. I get lots of loud pickups, and plenty of motorcycles. Arborvitae are my friend. They make good noise screening.
R(h)ubar(b) is tasty in pies, but you might might want to use rebar in a concrete structure. And it doesn't make for a very good faraday cage anyway. You need a solid conductor on the walls/ceiling/floor for a proper cage.
there would have to be enough money to upgrade handheld radios of over 250 firefighters at about $800 a piece.
Consider yourself lucky. Rather than fixing/adding repeaters for our old low band VHF analog system, we got a new Motorola 500 mHz trunking sytem that cost millions, and each radio costs $3200 (HT) and $3500 for a mobile. And they don't work any better. And all of our old frequencies are now each a talkgroup. So much for that dream of dynamic allocation of departments and equipment per incident that we were promised. Oh...and it doens't work as well in buildings. And the raios are bigger. The buttons are smaller. They eat batteries faster.
I understand that they are more capable as a system. But I'm not seeing that as some poor schmuck fire marshall/firefighter on the street.
What I've wondered is if they can't set up a system to prioritize calls through the cell phone system during an emergency, to allow first responders to communicate.
I don't know about any other US carriers, but Nextel does. Both for the directconnect (walkie-talkie type) service and regular phone calls. If I recall, there are 5 levels. 1.) scrub, 2.) 3.) Local emergency managenent/police/fire 4.) Federal Responders 5.) presidential entourage. I don't remember what 2 and 3 are....but you get the idea. If you are a higher priority, you bump other users if there are no more available resources on the tower or network.
How about a dual-mode phone? Unlock the GSM portion and you can have GSM service with CDMA as backup when needed. At least, that's how it works in China
Sounds like a good technical solution, but since there are no providers in the US that use both CDMA and GSM, you'd have a 2-provider phone. And I just don't see them cooperating enough to make that happen, especially with only one phone number.
We have a choice of standards hare in the US, and people are choosing CDMA over GSM.
Yes, because some of us actually care if we can make and receive calls or not.
I recently dropped T-Mobile. When I moved, I had crappy service at my house, if any at all, and going from my house to the next decent sized town, 10 minutes away was a complete dead spot.
Going from Trenton to Manhattan on the train was a series of dropped GPRS connections when trying to get work done on my laptop connected to the phone for Internet access.
As much as I hate their business practices (locking down phone features, etc.) and advertising, I got a verizon phone and have yet to lose service anywhere in my area and now have somewhere in the 800k to 1 MB range without a single drop on the entire hour and a half trainride to Manhattan.
I want my GSM back. But it needs to actually work. Yes, these are carrier problems, not problems with the standard. Yes, I know about the chicken and the egg. But I don't care. I need my phone to work.
Packets ariving out of order is jitter... Unless perhaps jitter means something else in the wired world.
Packets arriving out of order is only a possible side effect of jitter. Jitter means that packets are arriving at varying intervals, rather than in a predictable manner. You can have one packet every 10 ms, then one in 40ms, then 20 in 30 ms, then 1 ever ms and *that* is jitter. Its usually caused by weird pathing, where different packets take different routes, so when jitter gets bad enough, you often see mis-ordered packets as well. But that's not a necessity to call it jitter.
Some of us do more than play with computers in our parent's basements.
I have used VMWare GSX routinely for years in data centers running multiple VMs of the same OS. Sometimes for redundancy, sometimes so developers can have a "sandbox" to easily revert to. Sometimes to make an easily-deployable app server that needs to go to many locations. Sometimes because old crusty apps don't play well with others, and its easier to get vendor support when their app is the only thing insalled on the OS..........should I keep going?
Again, wha you are saying is correct, but the point you are trying to make with the observation is misleading. Yes, the both have motors, yes, they boh run on diesel fuel. No, they really aren't the same at all other than that. The accelleration curve required for a direct drive machine as opposed to a motor that spins a generator are wildly different.
Spamhaus is well known to block legitimate sites - my hosting ISP (very small, very special purpose - very spam intolerant) has a block of addresses that's between a couple of well known spammer-friendly ISPs' blocks.
So I'm going to guess they got the IP delegation from WorldCom.
And if you want anecdotal evidence, next time you get stuck at a busy railroad crossing near a rail yard (thus trains speeding up as they leave), watch the locomotive exhaust. It's hardly noticable. Now when the gates go up, look for a dumptruck and watch how much soot it blows out. And the locomotive has four engines roughly the size of the dump truck's cab....
Not arguing with the premise of your post, but this is just plain inaccurate and misleading.
You do not see much black soot exhaust fromt he train EVER because they (the deisel engines) runs at a fairly constant speed regardless of whats going on. The engines have very little capability to "accelerate", and wouldn't do so anyway, as it would throw the generator it is driving out of phase, thus making the power useless.
The diesel truck you see on the road is accellerating away from a dead stop, the least efficient operation it can possibly do. Diesels don't accellerate very well on their own accord, so its got a turbo jamming air in the intake as fast as it can get spun by the exhaust, and it dumping in as much fuel as it can burn based on that. And people are still bent out of shape at how slow he's going. Try comparing the diesel locmotive to this sasme truck while its on the highway doing 55 MPH.
that first one is LOUD when you first turn it on. These are the companies first rack-mount servers and it's been quite an experience.
Welcome to rack mount equipment. It's not designed to be where you are. it's designed to be in a different room, so they think nothing of taking 15 to 20 very tiny fans and making them spin at warp 12. The last Sun box I bough with 4 AMDs in it (can't remember the exact model...not at that company anymoew anyway) sounded a whole lot like you were sitting on the deck of an aircraft carrier when the fans were on high. Fortunately, they slowed down after the power and thermal management initialized.
Anyway....if you dont' have somewhere proper to keep them, eithr budget for something like an APC NetShelter or just return them now and get tower models.
Many of the heavy manufacturing plants use something like 440V three phase to power huge motors continuously, is a 34.5kV really necessary if a manufacturing plant didn't have the need?
He's talking about the primaries that come in. Not the stepped-down voltages that things actually run at. The transmission voltage on the primaries has a lot more to do with how far away from the substation/power generating plant your building is than how much power you need.
I don't know how much power a couple of electric smelters use, but I can tell you that a blade server farm can take some serious power and space. Most 200+ watt per square foot datacenters have MORE utility space per square foot than datacenter space (meaning you need a foot and a half or two sq. feet of space outside your climate controlled area to power and cool each sq. ft. of your datacenter). This equipment, plus the equipment inside uses massive amounts of power. A 60,000 square foot datacenter can consume 150,000 square feet of space and 20,000 kilowats of power, most of that at 208v. To supply the transformers with that kind of power requires a hell of a big set of primaries.
'If you buy a photo from a photographer are you allowed to post it on the internet?'
That would depend on what I bought, wouldn't it?
Yes it would. If he bought the photo, he could do anything he wants with it. If he bought a license for the photo, which is much more typical, then he could only do what the license specifies.
Any works on this laptop could be construed as being under the copyright of the creator, even if that creator is the one who sold the laptop. I could see an argument that the creator's copyright was in fact violated by posting the content, if the transaction was meant as a hardware sale only. Of course, I could also see a flip side argument to this.
Sometimes I wonder if I shouldn't have gone to law school so I could just argue for a living. But they wouldn't let me in after I passed an ethics test.
That may be the most insightful comment I've seen posted on this topic.
The only problem is, I'm running (legitimate) corporate versions of XP and Office 2003, which require no online activation. And corps demand this. And those copies always end up getting leaked/brough home with the IP staff/etc. I'm not sure MS is willing to listen to the groaning of that market in order to "crack down". I'm pretty sure that more than a few corps would be willing to seriously look at alternative productivity suites if that happened (online activation is an absolute disaster when you image machines).
I had one of the first Nextels (I was driving a triaxle at the time, so I was one of those early adopters on constructios sites). That was a long time ago....like 10 or 12 years I think.

For those of us in the US, its useful because paying for time on linked repeater networks gets real expensive. Not the iDen isn't exactly that, but it's priced better.
with automatic overdrive that applies to all gears, making them somewhere between a three speed and a six speed depending on how you look at things.
That's not at all what overdrive means, nor do passenger cars have some sort of second transmission that has a normal and overdrive setting.
Overdrive means that the gearing is higher than 1:1, and that's all. It's just another gear. It's not like a truck with a split rear or secondary transmission where putting it in high or low range effects the gear that you are in on the main transmission.

transmitting in the 800 and 700Mhz range. In other words; microwave technology
It's nowhere even close to microwave. Microwave is generally understood to mean 3 to 30 GHZ. Not 700 and 800 MHZ.

MacOS both seem to automaticly connect to these rogue networks and thus bypass any local network security I can enforce.
Huh?
MacOS can not find the preferred wireless network. Would you like to connect to "linksys"?
How is that automatically connecting to a rogue AP?
