If you are securing against unauthized users you clamp down at the DHCP server. If your are securing against unauthorized people leaching your connection, you secure at the NAT gateway. If you are securing from unauthorize people externally, you do it at the firewall.
All of this is network level stuff. It doesn't matter if they are getting in through a hard-line, a wifi connection, or a some well trained rats and a fiber splice.
Actually I've done more reading the the last year that I had the previous 10. I also tune in regularly to our local AM news station and NPR, thank you very much.
Yes standards suck. But the suck in a way that is consistant and allows other sucky things to talk to other sucky things.
I'll bet the 802.11b is a really crappy standards. But as long as I can pick up interchangable devices for $50 at the local computer store I'll live in ignorant bliss.
My point: XML is over-used for a lot of things. In some places it makes sense, but in many places it doesn't.
Ok. Name one.
(Silence)
You see a standard actually requires WORK to adhere to. I used to work with the SECS protocol for electronic transmissions in the semiconductor industry. Let me tell you, that was about 60 pages, single spaced. In the end we had a Tcl library that encode and decode from the SECS standard into something our software could use.
Now once you have a standard encoding and decoding suite I fail to see why it matters if you code it in XML, morse code, or smoke signals.
What I like is the fact I have only 1 parser to deal with, and that parse works with my current scripting solution. AND that format has a parser for most of the software I intend to ship software to. QED.
I'm on a 3 year replacement cycle for my data center. I can't get any budget for staff, but al long as it's remotely plausable I have a dapper budget for equipment.
Fill that with some florescent coloring a clear tubes. Throw in some black lights. You could charge admission.
I dunno. I have a 3.5 ton refridgeration unit for my data center. I can store meat in that room with the thermostat down.
Not really tied to the processor mind you, but it does toss a monkey wrench into Newton's law of cooling... Drop the room temperature 30 degrees farenheit and you will see a marked increase in the amount of cooling ANY type of heat sink is capable of.
Advertising was different back when they would hawk soap or light bulbs or toilet paper. You know, stuff that you USE on a day to day basis.
Now I haven't owned a TV in almost a year. My TV dosage comes in small one or two hour bursts when I stop over my Mom's place.
All I see are Ads for Beer, Computers, Cars, and Perscription drugs for old people. I'm pushing 30, I think most beer sold in the US is weasle piss, I'm set in my ways with scratch-built linux boxes, and I intend on driving my 3 year old car (just finished the payments - woohoo) till the wheels fall off. Now if there were commercials for products I was actually in the market for I might, just might be interested in watching.
Though I do have to say the IBM and beer ads are hilarious. Often more entertaining than the program on the tube. The Microsoft ads are hilarious too, but only in how completely absurd they are.
I haven't had a television signal in my home for almost a year. Whenever I go oever a relative's house you see them basked in the glow of the great american fireplace.
"Anyone want to go for a bear?"
Silence, stirring...
"Guys this is a re-run of a show I didn't care to watch in the first place."
Angry grunting that I'm interrupting their show.
"Say can we at least mute the commercials?"
Objects thrown. Cat's hiss. The room grows darker.
Hmmm. My mom complained (loudly) for about 2 months about why her sound wasn't working. I had my brother walk through the control panels, and hardware wizard, everything.
Finally I show up, and hit the power button on the speakers.
Hmmm so Soyuz was the greatest thing since sliced bread Can you tell me why? (besides that it just "works")
Exactly that, oit just works. It also happens to be a hell of a lot cheaper, and can reach a much higher orbit than the space shuttle.
...but it is a hell of a lot cheaper than the old apollo/soyuz mssions that used "disposable" parts...
Well a) Apollo was going to the moon and b)the requirements for performance on the components of the space shuttle are so insane that engines barely last 3 launches before needing critical parts swapped out. High-performance is mutually exclusive with re-usable.
Think of a car that needed to be replaced after every fill-up of gas. Would you be clamoring for this "new" technology? Or would you rather put some maintence/oil/gas into an object that didn't cost you 3/4th of your yearly income to operate?
The space shuttle is not a family car, it is more like a drag racer. It undergoes insane loading for a few minutes at a time, and then has to make an insane stop. The professional grade drag racing car engines are designed to last one race before being rebuilt.
THe only reason the Shuttle has a design life of 100 flights was to justify the expense of building them. There is no way with the extreme loads put on them they will ever last that long.
Screw "safe". That just seems to be a euphamism for "it will cost so much we can rarely do it." What we need is to stop dropping a bundle on a single complex monster of a system, and instead break the task up over a few simpler alternatives.
A safe human transporter is a lot easier to build if you aren't trying to put mondo amounts of stuff in orbit. Putting mondo amounts of stuff in orbit is a lot simpler if you don't have people on board. Frobbing items in orbit is a lot simpler if you aren't trying to carry the equipment along each launch.
We have 2 out of 3 already. The ISS can take over a lot of the reasearch the shuttle used to do. The Titan and Delta (and the Russian stuff too) can take care of the heavy lifting. We need to design something to get people up and down, and no extra frills. Or better yet, buy the Soyuz from the Russians.
*ALL* future shuttle flights should be equipped with a Canadarm, ISS docking ring, EVA packs, and enough fuel to get to the ISS.
A half a billion dollars a launch, I wonder why this wasn't done already. If all that money was not going into safety, the Joe taxpayer in me wants the current team out and a new team put in.
The shuttle was a great experiment. We've learned our lesson. Let's buy some surplus soyuz to hold us over until we can get our own expendible launch fleet together. The only place the last 3 shuttles belong is a museum.
God, between this post and previous article about houses I wonder it historians 1000 years in the future ares going to look back at the 20th century and think we must have reverted to the stone age. Or maybe we lived a strange immaterial existance. Why else are there no remnents of housing, or roads, or even buildings. (Skyscrapers have a life of 100 years before they have to be torn down because of metal fatigue.)
Okay, we WILL be leaving behind mountains of trash that future cultures will probably be mining for raw materials.
Far better to spend your time working on something that will be remembered 400 years in the future, or better, will live on. This may sound a bit hackneyed, but a home is not made of brick and morter, nor wood, nor steel. A home is made of people.
Buy yourself a cheap house, and spend your money on your kids.
I live in Philadelphia. European settlers have been building in Philly since the Swedes in 1640. It was the first planned city in the world, all of the major streets are still in their original location. They were deliberately built wide, and in a grid pattern.
Philadelphia is also home to the oldest continually inhabited street: Elfrith's Alley. Some of the homes there are all well over 300 years old.
The homes are all brick townhomes, about 4 stories tall. They have been kept in good repair for all of their existance.
Most of them started off as rental properties for Sea Captains and Trader's who frequented the city. They whole block narrowly dodged a fire in the 19th century, and were almost demolished to make room for I-95 in the 1950's. The only thing that saved them was a community organization and a historical designation.
I think someone about pointed out: having a house last hundreds of years is primarily dumb luck. Continual upkeep and habitation helps. After a while you need nothing short of a historical designation to keep it from being knocked over by progress.
Unforunately all polymers experience a phenominon known as creep. Over time the material develops a pronounced bend in the direction of stress.
If you want a great example, buy some of that cheap plastic shelfving, and store some books on it. In 6 months you will have a nice permanent dip in the middle. Left alone, the shelf would stretch itself out to the floor.
Creep actually tears the chains of molecules, so flipping the material over periodically won't help.
Now, steel reinforce the plastic and you might be on to something...
Sounds like neural net, but without the "learning" process of trying random things then assigning a weighting value to it based on how it worked out...
That isn't a dark spot - that's just a collection of the densest matter on Earth.

New York (AP) - The heaviest element known to science was recently discovered by researchers at the University of Fulchester. The element, tentatively named Administratium, has no protons or electrons and thus has an atomic number of 0. However, it does have 1 neutron, 125 assistant neutrons, 75 vice neutrons and 111 assistant vice neutrons. This gives it an atomic mass of 312. These 312 particles are held together by a force that involves the continuous exchange of meson-like particles called morons.
Since it has no electrons, Administratium is inert. However, it can be detected chemically as it impedes every reaction it comes in contact with. According to the discoverers, a minute amount of Administratium caused one reaction to take over four days to complete when it would have normally occurred in less than one second. Administratium has a normal half-life of approximately three years, at which time it does not actually decay but instead undergoes a reorganisation in which assistant neutrons, vice neutrons and assistant vice neutrons exchange places. Some studies have shown that the atomic mass actually increases after each reorganisation.
Research at other laboratories indicates that Administratium occurs naturally in the atmosphere. It tends to concentrate at certain points such as government agencies, large corporations and universities and can usually be found in the newest, best appointed and best maintained buildings.
Scientists point out that Administratium is known to be toxic at any level of concentration and can easily destroy any productive reaction where it is allowed to accumulate. Attempts are being made to determine how Administratium can be controlled to prevent irreversible damage, but results to date are not promising.

I used to work on a factory floor. The parts that failed most often were cooling fans.
Most of my applications could run comfortably on an 800Mhz processor. And that's a database. Everything else is throttled by Disk I/O or network I/O

Actually we has one torn down in Philly. It caught fire halfway up. The fire burned only 3 floors, but they had to tear down the whole stucture.
It took them 3 years.
Exactly that, oit just works. It also happens to be a hell of a lot cheaper, and can reach a much higher orbit than the space shuttle.
