No, the problem isn't the head of a good IT department, it's folks with no IT department.
Your average Joe who buys a laptop from CompUSA doesn't have an IT department. He may be able to call Dell/HP/IBM/etc. tech support, but they might not help.
The problem is, most of the obnoxiously spyware-infected machines are personal machines on a cable modem, not corporate desktops.
So, really, faulting the non-existent IT department of Average Joe's non-existent business is really not too helpful.
I have 1 email address that I have used for many many years, far before spam was a problem. The problem is, my email address has passed beyond my control. You can still find it on the 'net in usenet archives, mailing list archives, and who knows what else. The point is, 10 years ago, we didn't think to conceil their addresses... they wanted to make them easy to find so that people could find *us*!
Even better, somehow, there's a database that matches names to email addresses. People other than me map to my email address, so I get "legitimate" spam.
Furthermore, not loading the images and not clicking on the links doesn't fix the problem entirely. I've checked, depending on which address they've spidered. Contact addresses for my web-design business that I shut down 3 years ago are still getting spam.
That I have to change an email address that I've had for nearly a decade... well.. it makes my blood boil.
However, it's also the case that if it was cheaper to ensure proper disposal of a satellite, more people would do it. It would also be more likely to have robotic tugs designed to pull satellites down from orbit.
Not necessarily. It probably holds for most heavier satellite applications that if you can only get 10,000 lbs up per flight, but the cost per pound is sufficently low, satellites that are assembled in space out of launched components start to look good.
Which, really, make sense. I mean, in the real world, big stuff is usually shipped dissassembled and then assembled on-site.
Also consider that the National Geographic society invests quite a lot of money sending photographers to strange and beautiful places on earth and in the ocean. I've often wondered if the solution to space exploration is merely making it easier for folks like them to launch space missions.
It's probably the case that, if Falcon I and Falcon V do well, NASA's going to end up dealing with SpaceX anyway. It'll make for some great congressional hearings if they don't.;)
You assume that a scramjet will ever be viable enough to be worth bothering with. Remember, any hypersonic air-breathing engine needs to be lighter than the equivelent amount of oxydizer that an equivelent non-air-breathing hypersonic engine needs. And you will need some rocket power to manuver in space.
Well, first, it's a huge business risk. People *have* tried to step in, but nobody has managed to do so successfully. Check out astronautix.com and browse their database for a whole load of things that were promised to be cheaper but weren't. Garry Hudson has tried several times, in fact.
Second, because NASA has done much to discourage competition. Like the point in the 80s where they were trying to shut down Atlas, Delta, and Titan so that everything would launch on the shuttle.
Actually, it's a bunch of equations in a Linear Programming problem.
Part of the reasons why satellites are so expensive is because the cost per pound is so high. Reduce the cost per pound, you need to spend less time and money making it so lightweight, which means you can spend time and money making it last longer, cheaper, more functional, etc.
Reliability for unmanned launches ends up being such that, currently, 98% launch reliability is "good enough" because going beyond that ends up being far too expensive.
PCS is the name that Sprint operates under and the name for the 1900 MHz band that they operate in.
Sprint PCS is CDMA 1xRTT or CdmaOne (the slower, 2G predecessor to 1xRTT) like Verizon.
But you are right in that neither the CDMA (IS-95) nor the TDMA (IS-136) standards include the notion of a SIM card in the standard, so nobody has one.
In order to sell *everyting* he owns of Microsoft, somebody needs to be able to buy. This is normally covered up by market makers, specialists, etc. but with the percentage of the company he owns, they'd offer him a small fraction of what his shares were worth because he was dealing in such a huge block. You can't divest that many shares of stock that quickly.
Except that your average customer's head is already having problems differentiating between DVD-RW and DVD+RW. Add back DVD-RAM to the mix and we're talking about full cranial explosions here.
If critical backups get messed up because of security testing, that would be a security hole.
Having the sys admin go spastic is a good thing for them, because that means that there's somebody watching for stuff. If they know the IP addresses, they can just block those addresses if they don't want the results to turn out bad.
EDGE and GPRS "steal" time slices from GSM traffic on a single band. The problem is that GPRS slices are only used for data, not voice. I'm not sure about EDGE, but since most phones can't use it, it's all academic. All of these can exist within a single 200 kHz GSM channel, sorta.
UMTS/WCDMA/3GSM (depending on weather you are speaking to the sandards folks, the hardware folks, or a salesperson) is completely different. As an added bonus, you have a 5 MHz wide channel that you need *all* of in order to work. So UMTS is going to be a fun rollout.
CDMA 2000 (1xRTT, 1xEV-DO, 1xEV-DV) all uses a 1.25 MHz wide channel, which means that it's easier to roll out. Except for EV-DO, everything's interminglable.
The hard part is that the 800 bands are really stuffed with AMPS and TDMA technologies, so the rollout of even GSM to those bands is hard. Meanwhile, Verizon has an easier time of rolling out new frequencies becuase they've been on CDMA the whole way along, plus 1xRTT has already started rolling out. And the 800 and 900 bands go through the walls much easier, so you want your premiere services there.
I'm guessing that EV-DO is on 1900 while 1xRTT is on 800, but I could be wrong.
There are supposedly CDMA Bluetooth phones on the way, but it's not necessarily likely that the EV-DO network will be available on said phones because it doesn't contribute to the phone's essential platonic phone-ness.
Wait another year or so when the 1xEV-DV rollout happens and then there'll be some neat choices.
I always liked the Ricochet model. Dead-simple low-power transmitters all over means that you can have tiny cells with only a few users per. Ricochet was intended only for the cities and only works "downtown". The good part is that they can tolerate the loss of an individual cell because of the overlap, which makes maintenence slightly easier. The trick would have been to also set up cell-tower-like relays in the surounding areas.
This is just using turbo codes and CDMA modulation with the same old antennas as a cell phone.
The technology has been there for the past few years to get broadband to your parent's town, but just not any interest in productizing it. However, as the Internet becomes more ingrained in people's lives, there's no choice.
Also, terminology help: ILEC = Incumbent Local Exchange Carrier = local phone company CLEC = Competitive Local Exchange Carrier = competition to the local phone company
1xEvDO is a stopgap. 1xEvDV is the big one, and 1xEvDV will be able to intermingle with 1xRTT.
It'll be interesting because you can't intermingle UMTS/EDGE/GSM like that. And ATTWS/Cingular is still un-rolling-out TDMA.
Although, they do have the hope, once they get rid of TDMA, of using the 900 band instead of the 1900 band, which gives them better wall-penetrating abilities, which is the main reason why Verizon often has good coverage.
The odd thing is that the idea of a wireless bluetooth headset is very long in the...ehrm... tooth. Support for it is in the standard, but they took their time including bluetooth chips in the phones.
And, really, a tiny Bluetooth earbud that you pull out like your stylus (shades of star trek, really) is what would make a Treo form-factor phone more marketable.
The other problem, I think, is that nobody's spent the time to really think of some whack applications other than that to sell it. The Bluetooth GPS paired with the digital camera that notes the current location, time, etc. The digital camera that queries all of the people in the area's PDAs for their business card so that you know who's in the picture. Off-the-wall stuff like that which nobody's given much thought to writing universal interfaces and support for.
Haven't you heard about the potentially upcomming V710 from Motorola?
The big thing about EV-DO is that it's data-only, with no voice network with it. So the assumption is you just buy an EV-DO card and use that.
The other problem is that Bluetooth is unfairly been victimized by wifi hype and, at the same time, not yet been done "right" in such a way that it becomes a must-have feature.
I live in Comcast area. There's no "Business Class" with Comcast. There wasn't with AT&T@Home or AT&T Broadband, who preceeded Commie-cast. Besides, I get Speakeasy, which is, as you said, even better.
The way I see it is that I hate both Ma Bell and the Cable companies, but Ma Bell has a network that, excepting the random natural disaster, just plain works because for the past 50 years, a person who can't call 911 when they need to is generally on their way to picking up their halo and etherial wings, whereas a person who can't watch the TV is merely on their way to being annoyed.
