IBM sell a LTO2 tape drive with autoloader, about $10000, capacity of 200GB uncompressed per tape (400gb with hardware compression), capable of holding 7 tapes, giving 1.5TB of storage for a fraction of the cost of a raid5 array of similar storage capacity and reliability, all in the space of a shoebox.
How much is this remote backup site link going to cost when you're going to copy 400GB of data a day to it? over here in the uk you'd be looking at $100k or more a year if the distance was anything meaningful (more than the length of some ethernet), a smidgen more than the cost of replacement tapes every year.
Then you take 1 tape every week or month and chuck it in a bank vault to provide the ultimate fireproofing.
We do have a remote backup site with a 15 mile fibre connection to it, but its there for speed of recovery, not because of any fantasy concept of it being cheap, it's massively more expensive than any other solution available.
Dont know about other linux distributions, but Suse allows you to use blowfish, suggesting they all can. The reason for not doing it is backwards compatibility with other Unixes.
However, there's also raid1+0 (or 0+1 depending on the implementation), which is now generally the standard for mirroring, at least in the systems I use. So you get each piece of data mirrored between the 2 disks, but the system is also a stripe, so you get a (not huge) performance increase for reading.
The security side is a joke - If you are connecting to work to download that critical report, you're going to be connecting to a VPN, whether it's IPSEC, PPTP, or SSL based. Each one of these is more secure than the WEP or WPA based security that a commercial hotspot will be providing.
Diseases do exist which can kill millions of people, haven't you noticed?
AIDS, Bubonic plague, and I'm sure dozens of others I don't know about, either have or are currently killing millions of people. Barring medical breakthroughs, AIDS will kill every one of the 40 million people currently infected with it. The Bubonic plague wiped out a third of Europe, today with increased travel it could be a third of the world.
37.6mpg (UK so 4/5th of that for US) is what I get in my car, it's not a diesel, it's a 1.6litre petrol engine. That's my own calculations over the 2000 miles or so I've had it.
It's rated higher (about another 10mpg), but I don't drive it very sensibly...
That just shows how shocking the USA fuel consumption is, the Citroen C3 (a smallish 4 seater) gets 67.3mpg (UK so 55ish US) in its combined cycle, 76.6 maximum. And it's certainly not the most efficient car out there, I've read the VW Lupo can do about 80mpg.
I think it's more commonly the other way around, it certainly is here - we've already got the CALs, work just went "500 employees, 500 CALs", and made Exchange+Outlook the standard setup.
Now we can choose whether to run Windows+Outlook (which work had already bought in a bulk licence), or Linux+Evolution. It doesn't save money in the short term, but it does increase the possible ways of working, and it does massively help if you're planning on doing a migration to Linux over a period of time.

Over here in the UK, and I think most of Europe, signatures are being phased out as too easy to forge, especially when checkout staff ignore them so much. Instead, you have a PIN like at the ATMs, that you have to type in then the machine authenticates you.
It's probably less secure than a well checked signature, but it's an awful lot more secure than an unchecked one.
I guess because sometimes mindshare is more important than money, especially when you have a 95% monopoly anyway, which will give you more money than you can ever spend.
Yeah, if you look at the acknowledgements section at the bottom you'll see Cisco and Jupiter networks, probably the people most affected by this, so they've obviously had a while to work on fixes.
You've been able to grow the AIX LPARS dynamically in various ways for a couple of years now, adding CPU and memory is just a case of clicking an arrow in the Java management gui used.
AIX5.2 does require the allocation of an entire CPU, hard drive, and network adapter to each partition though, and this is the real problem - there's no hardware virtualisation.
The AIX5.3 update and the soon to be released Power5 hardware supports 10 partitions per CPU, and virtual disks and ethernet adapters.
I saw pishing attempts using the IE bug where it didn't display the correct url if you embedded a control character in it during the gap between the bug being released and Microsoft released a patch a couple of months ago.
Sendmail is very big and complicated, so it has lots of opportunities for bugs + security holes, but it's also very popular, so it gets the whole "many eyes = shallow bugs" thing, so perhaps its repution for security issues is more to do with the number of people looking and finding bugs compared to other email systems.
XFree 4.3 is not dramatically different from 4.4, and if the 4.3 fork were to gain momentum you'd find very quickly that people who had contributed code to 4.4 would simply resubmit it to the fork, on the basis that whoever wrote the original code can resubmit it to anyone they want unless they transferred the copyright to the Xfree project.

Not sure about those 3, but power4 which is 64bit uses 4kb, i think everyone does.

It's more common in the UK if you get a 2nd phone line installed instead - at that point you just get a splitter installed not a 2nd line.

So, no it's not a miracle car, just a normal one.
Ewan
Even 22-27mpg is bad to a European. I get 40mpg in my fairly sporty car, the everyday version of it gets about 60mpg.
I'm not aware of any "normal" 2WD vehicle on sale in the UK which would get 22mpg, even given the 1US gallon = 0.8 UK gallons conversion.

Since it was Novell that opened up Yast after Suse had kept it closed, i'd be surprised if they made this anything except a module for yast.
But then again, it is Novell, they could make the configuration tool Windows only..

It remains illegal if the first request of "take a look" was actually "look at this stolen property".
Reverse engineering is only legal when the original access the specs were built from was legal, e.g. decompiling a binary.
