Re:Let us not forget ...
It's good to see people being complimentary about Mosfet.
Sorry, had to be done.

Re:What exactly does this do?SC Test aims to produce regression testing software. This basically means that when software has new features added, regression testing tests to make sure it hasn't taken a step backwards (regressed). In plain english, regression testing tries to prevent new features from introducing bugs. A good introduction to regression testing is at AutomatedQA, although the software there is commerical their few words on regression testing are well worth reading.
This is what Webopedia has to say on the subject:
The selective retesting of a software system that has been modified to ensure that any bugs have been fixed and that no other previously-working functions have failed as a result of the reparations and that newly added features have not created problems with previous versions of the software. Also referred to as verification testing, regression testing is initiated after a programmer has attempted to fix a recognized problem or has added source code to a program that may have inadvertently introduced errors. It is a quality control measure to ensure that the newly-modified code still complies with its specified requirements and that unmodified code has not been affected by the maintenance activity. -

Puh-lease
Anyone who thinks "Magic Lantern", the FBI's Grandiose excuse for a keystroke logger, should have a virus template is not familiar with what a computer virus actually is. For the faint of wit, I'll break out the definition:
A program or piece of code that is loaded onto your computer without your knowledge and runs against your wishes. Viruses can also replicate themselves. All computer viruses are manmade. A simple virus that can make a copy of itself over and over again is relatively easy to produce. Even such a simple virus is dangerous because it will quickly use all available memory and bring the system to a halt. An even more dangerous type of virus is one capable of transmitting itself across networks and bypassing security systems.
Some people distinguish between general viruses and worms. A worm is a special type of virus that can replicate itself and use memory, but cannot attach itself to other programs.
First of all, Magic Lantern does not replicate. Second of all, it is not malicious. Magic Lantern is not designed to break the law but to enforce it. If McAfee made a "Law Enforcement Tool Scanner", then we could attack them for not doing their job. Since they make a virus scanner, and we're not talking about a virus, the whole conversation is silly.
Why don't people bother looking up the definition of a word before posting a story about it??!? -
Stuff this in your pipe...
From The Beast:
NTFS volumes can theoretically be as large as 16 exabytes (EB), but the practical limit is 2 terabytes.
That's a 64 bit addressing space, and yes, it's supported on the consumer desktop OS that's been shipping by same for just a little while now.

Website clustering
If you just want to setup a web server, you don't really need to do a Beowulf cluster. There are a lot of ways to split web traffic load among different servers.
The easiest would be to separate your program out serially, rather then in parallel. (So, for example if you needed a database, you could run the database on one machine, and the HTTP logic on another). If you had three or more machines, you could use one of them as a 'dispatcher' as a sort of proxy server that would send requests to different machines to split up the traffic. With just two machines, I suppose you could use round robin DNS where different computers would get different IP addresses for your domain name, so the load is distributed among your boxes. You'd probably have to run your own DNS server, though. Finally, if you're just serving static pages, you don't really need to worry about anything. Just about any PC on the market today can do thousands of hits per second of static HTML. More then you'd probably ever need. -
Re:This would be tough to fight
Maximum connections per IP series (correct me if there is a better term for XXX.XXX.XXX.*)=2
IP classes
Class A - supports 16 million hosts on each of 127 networks
24.255.255.255
Class B - supports 65,000 hosts on each of 16,000 networks
24.45.255.255
Class C - supports 254 hosts on each of 2 million networks
24.45.126.255 -
what is broadband?I always thought "broadband" meant wire, of some type, that could carry multiple kinds of information (cable TV, telephone, DSL, etc.).
In this article, "broadband" seems to be used to mean "big fat pipe."
Maybe I'm being a nitpick?
Maybe not: I found a definition of broadband that jives with my own definition.

Re:Isn't static RAM dangerous?
The place I found a definition of NVRAM listed both descriptions - a battery-backed SRAM or an EEPROM, though, upon closer reading, the latter is more of a combination of an SRAM chip and an EEPROM.

Bubble Memory ?Anyone else remember bubble memory from the 80's ?
That was magnetic based and non-volatile and I seem to recall it being used in a series of portables from some manufacturor like Sharp.
I've got a nagging feeling that one of the reasons it didn't take off was access speed. I wonder if this new approach is at all similar, and if so what they have done about any performance issues.
I mean if it required dirty great RAM cacheing to make the performance acceptable surely this would be a reinvention of the hard disk ?( joke )
