The spectrum is only a scarce resource because it's used so very, very, inefficiently. Often, there is just one omni-directional broadcast antenna occuppying a certain frequency covering several miles, which may only be used by a few people. For example, CB frequencies waste lots of spectrum, and most of the time the channels are empty until someone actually talks on one of the channels.
If the majority of wireless transmittions were required to be digital, that would significantly reduce wasted spectrum. Also, wireless devices should be able to automatically hop to available frequencies instead of allocatting them to begin with.
Sort all users e-mail recieved by size for a given year.
Delete 5% of the largest e-mails. These will probably account for around 90% of all disk usage. They probably represent file attachments which should have been stored on a server instead of in an e-mail account anyway.
Just think, when you mail a 2MB attachment to 3,000 people in a division, that could use quite a bit of disk space.
I think you have your terms confused. Nuclear reactors are sub-critical, meaning that the fusion reaction is not exponential like it would be in a nuclear weapon where you want all the energy released at one time.
Also, the way fusion reactors are designed, I assume that a critical reaction would be almost impossible given the grade of material used.
I guess you didn't see this? They don't trust their citizens to own guns. No worry for the muggers! They don't have to risk being shot to steal all your high tech gadgets.
Doesn't anyone remember the days when we had full graphical user interfaces in less than 8MB of RAM? What's this about needing 128MB of ram? Where did all our memory go?????
okay, here's a challenge...

Is Swap Necessary?
·
· Score: 4, Insightful
Does anyone out there want to run a series of benchmarks with a few standard applications to prove/disprove whether disabling swapping improves performance?
I'm tired of just hearing antidotal evidence on this. Everyone has their stories about turning off swap files and improving performance, but in what cases? Are there some users this would harm?
TV signals being broadcast are in public air space, unencrypted, and you don't have to pay a fee to watch them. Why should DRM apply to them?
I usually support the software and music industry regarding their copyrights but in this case it doesn't make sense. When I purchase a piece of software I'm bound by a licence agreement, a contract on my use of the software that I paid for. With broadcast TV, you have not agreed nor signed to such a contract, therefor, how can DRM be enforceable?
How do you define a copy of broadcast TV anyway? It's being transmitted from a base station that could reach an infinite number of devices. The issue is really about a consumers ability to TIMESHIFT the video so they can watch it at a later time.
No, hardware and software vendors won't automagically switch all their apps to Linux just because people stop pirating Windows. Microsoft will still command a large market share of PAYING customers. You're forgetting that consumers are just a small portion of the entire market for Windows. 99.99% of all businesses will pay for software because the legal consequences for them are real, unlike the average "consumer" pirate.
The more difficult Microsoft makes it to pirate their OS, the more paying customers they will have. The reason is, most people are not l337 h4x0r5 with hours available each day to waste looknig for potentially unreliable, virus infected warez.
Linux will have more support and more games? I've not seen this trend to date.
You must support piracy seeing as you feel the need to defend your feeble argument and use profanity against someone you disagree with.
I actually built a computer and then PURCHASED a copy of Windows XP to go with it. You get somewhat of a discount if you buy hardware/OS together, but it still cost me around $120.
It's not worth my time to warez it, and I don't believe in that anyway. If you don't like the cost of Windows use linux and stop complaining.
I don't understand why, but most people don't realize that most new copy machines are also PRINTERS and DIGITAL SCANNERS. I always find it funny when companies purchase fax machines/scanners/copy machine/printers when they really only need one device.
If you can find access to a digital copier at your university somewhere, you can just put the whole stack of paper in the sheet feed and it should be able to scan every page double sided and put it on a network drive somewhere.
It might take awhile to figure out how to set this up, but it's infinitely easier than trying to scan each page by hand using a crummy consumer scanner.
This sounds very cool. Now I could convert my NSF or SPC (NES and SNES) songs and play them on a cell phone! It's always fun to have a ring tone from some from some obscure game and see if anyone recognizes it.
drain 'em till their dead before recharging them This is only good for Nickel Cadium batteries, which are seldom used anymore.
Most manuals for devices using NiMH and Lithium Ion say the batteries last longer if you keep them charged up (topped off). Otherwise, the deep charge/discharge cycles put a lot of wear on the batteries.
another evil thing is Registery Keys. These too have per/user permissions which makes it infinitely more frustrating to lock down a program or open one up to certain users/groups. I think this accounts for about half of the 90% of my programs. Again, it's just not worth it playing safari in the system registry trying to hunt down the correct registry keys to make things work.
This is what needs to be done to windows to fix most of these problems. User accounts SHOULDN'T be allowed to install programs into the OS's system folders. Even if you mess up your user account it should not effect the OS in any way.
I tried running as a regular user on Windows XP Home edition before. Unfortunately, about 90% of programs are impossible to run after installing them as an Adiminstrator user under Windows XP. Of course, a lot of this is from programmers always assuming that whoever runs the program is a memember of "administrators" and thus try to do things like read/write configuration files in the programs directory instaed of creating configs in the USERS home folder (Documents and Settings).
XP Home addition also has a very poorly designed system of user rights for admin vs. regular users. You can't even set folder permissions! I guess they think that only those who purchased the "Professional" eddition of XP deserve that feature.
As much as I would like to print things in metric, it's not like I can just go down to Staples or Costco and buy a box of A4 laser paper. Not to mention the other varieties and qualities of paper that are normally available in letter sizes (weight, brightness, laser, copier, transparency, inkjet, photo). Even if A4 sizes WERE available, I'm sure it would cost 50%-100% more since it wouldn't be produced in bulk here.
As long as U.S. manufactures make paper for the U.S. market I don't think we'll see A4 becoming popular anytime soon.
text-decoration: blink. hmm... what else could blink possibly do? I guess Internet explorer ignored that CSS property for some reason, but it's ugly on Mozilla. Fix your website plextor!
I guess Microsoft decided to finally write their entire OS in visual basic (.NET?). Good job!
4-6 GHz is ridiculus. It's obvious they are not designing the OS to scale with a wide range of processor speeds, either that or they won't be releasing it till sometime in 2012.
The question is, what are all those CPU cycles going to be doing?
DirectX still requires games to use verticle sync which reduces frame rate about 50%. You can try to force it off, but then the game is unplayable because user input is somehow timed to the framerame and mouse sensitivty for example, becomes completely inconsistent.

How to save 90% of disk space:

Just think, when you mail a 2MB attachment to 3,000 people in a division, that could use quite a bit of disk space.
Features like autocompletion, syntax highlighting, debug environment are essential for saving developers time.
Going without these features is just folly.

hmm... great logic there. Snuff themselves out of a market share where people don't pay them any money? What a tradgedy that would be...
