Heya,
At our routers and firewalls, we ban ALL traffic both inbound and outbound. Then we only open ports that we need (i.e. 80 and 443) in the directions they are allowed to go!
Our MS SQL boxes have not been touched! It's great.

Heya,
The 2GW output power is the peak output power. When you realise that an RF emitter has (at best) a 20% efficiency (similar to modern radars) then you realise that this must be a pulse over about a millisecond. This means that the average power out is a small 1KW. This is much more feasible given the space restrictions inside the cruise missle in which it's to be mounted.
Also, it should be noted that this is NOT an EMP weapon. It is the voltage field created that destroys the silicon.

Most modern radars have attenuation and can handle a wide range of RF frequencies. This can be from 0.5 GHz to 40 GHz. Mobile phones and current WIFI inhabit the 2.5 GHz range (commonly refered to as CD band) and is dealt with seperately to the rest of the microwave bands (E-J and K). A WIFI adapter will NOT jam a military radar but rather show up as an unknown emitter which in a time of war will generally cause the ship/plane/helicopter to go "defensive" and defend against the potential threat!
1. Yes - if you squash the Gummy Bears into an A4/A3 sheet. 2. Yes - the cat will probably not like it though. 3. Yes - Uncle Bens "5-minute" is best. 4. Yes - for a short while; then it'll go *beep*, *beep*, *beeeeeeeeeeeeeeeeeeee ack cough splutter arrrrggghhhhh die* 5. Yup - Nasty crosstalk and data corruption would probably occur in the data lines.
Its not all that bad - my assembly code in a CPU identifier works fine on both Intel Pentiums / IVs / XVVIIIIIs, and AMD processors. You just have to make sure that you depend on use of any processor specific features unless you know exactly what processor you're running on and have a backup for other processors that don't support that feature.
MP3 players are wonderful things but the main thing putting me off is the lack of supporting hardware.
Before everyone gets upset - I understand that you can use your computer etc. and download music but what happens when someone decides they don't want to wait for their computer to do whatever.
How about a docking station that you put your CDs into and it compresses the CD (or track if thats what you want) and stores it on the player. Automagically like! This combined with an FM tuner or cassette player would save people having to buy / setup dodgy connections into their computer sound cards... Hell, DAB radio is taking off - why not have a DAB tuner?
Just a thought.

Your hardware under Win2K and Linux

Just for the balance of fairness - my hardware:
MS IntelliEye (USB) - Works wonders under Win2K and WinXP but in RedHat 7.3 and 8.0 it works during installation (in X) but not post-install when you're running X normally.
NVidia Geforce 2 MX - Works under Win2K and WinXP but SuSe really, really, REALLY, doesn't like it.
Adaptec 29160 with 5x SCSI HDDs - Ok under WinXP and Win2K installers; Gentoo 1.3 and 1.4 Beta suck and die claiming that there is either a) no disks present or b) the empty (partitioned) 18gig drive has less than 250MB of space.
Go figure - Like the author of the post who started this debate - I cannot be bothered playing with a text config file or downloading that config file (and/or source plus compiling it). I just want the hardware to work, drivers to install with very little effort. My computer is to do work on; NOT to fiddle with until I can do work on it.
Your argument is based around the cost of software being excessive. Well lets see; I was a student until recently (June 02) and I've bought all my software so...
1. Windows XP - £15 inc VAT
2. Office XP - £25 inc VAT
3. VS.NET Student Edition - £65 inc VAT
Grand Total: £95 (or $63 USD)
Perhaps you should check what people do before assuming that MS software is very expensive.
I own my own modem and pay for a wires-only install and service...
If my modem were to break down and start sucking bandwidth like there was no tomorrow and the FBI (unlikely in the UK but hey) broke down my door etc. I would tell them that my modem was broken. Hey, if there was going to be a problem for more that a couple of hours etc, I might even email my ISP and tell them there was a problem.
Oh dear God - the hassle of sending an email! Gee I don't know if I can stand the work!
I use to run the web servers amongst others for Heriot-Watt University Students Association. On this box we run:
Windows 2000 Server SP2
Apache 2.0.36
Bind 9.2.1
It has now been up for 4 and a half months and the last reboot was to install SP2. No version of *NIX can upgrade its core software (i.e. kernel) without rebooting. I do NOT to that it is fair to say that Microsoft software will only work on under-used workstations and when not connected to the Internet. This web server serves out > 410,000 hits a month on a P2-300 with 128 MB Ram. Please, people check your facts before you start accusing Microsoft software of being completely useless.

When a government department adopts a Unix-based solution, it's because they're far sighted and everyone gets a pat on the back.
When a government department adopts an MS-based solution, it's because Microsoft is in league with the Devil and are trying to take over the world.
How about some sense prevails and people realise that for some things, Microsoft may actually be better!
