well, a scramjet will take you from an initial Mach 2-3 to the expected mach 7-10+ this technolgy is meant to achieve...
So you will still enjoy all the noise of the starting point up to mach 1, then have a nice, quiet acceleration to mach 2-3, and then suddenly leave all sound you produce about 500-600 feet behind you, instead of just the 70 feet sound buble displacement you enjoy at mach 3.
the whole point is that to you it will be quite silencious...but it really have to be made in high altitude...
If you were to engage the scramjet at low altitude (say launched as a missile from a mach 2.4 fighting plane) just the sound wave decelerating from the missile at low altitude would be sufficient to damage any building within a 2 mile radius...not to mention deafening a few tousand people.
Then, on impact, I think you can dispense with unstable/dangerous explosive... you just need some hyperdense material at the tip, say 5 kg depleted uranium.
Now, if you caculate the inertia of 5 kg at mach 7-25, you will find it's a very damaging little kinetic monster you just created.
after all, the FIRST implementation of that thing is to be a missile in 2010-2015...so lets see what the probable effects will be...
E=mv^2
5000grams*(330m/s*(mach 7 to 25))^2
5000*(5336100 to 68062500) 26 680 500 000 to 340 312 500 000 Joules at impact...seems quite an energy dissipation problem...for the target, I mean 8p

all his copying, untarring, editing and modifying where made on the device network share-drive, him being short on space and all...
so you don't need to fiddle a lot with the box, except for plugging in usb, which any luser can do.(?)
he didn't even have to crack the password: "As expected, the passwd file showed the user accounts I had created with a/dev/null for the shell. But there were two accounts that had a real shell: root and an interestingly named account--ourtelnetrescueuser, that looked like a back door account used for debugging or recovery purposes.

But in order to use these accounts, I would need to have their passwords. I started down the path of cracking the passwords before I came out of my stupor and realized all I had to do was edit the passwd file and replace the encrypted password with a known encrypted password from one of my other accounts! I could also just add a valid shell to one of my accounts, but for starters, decided to just put a new password in for root and leave the rest of the accounts alone. "

For the case, I took the Cooler Master STC-T01, a bit overkill, but I was a anxious of overheating...also, it provides room for another 4 disks, but I will need another psu to power 12 disks....
The disks are quite silencious, and the 3Ware card allow for staged disk spin-up, so I was able to run it all on only 1 PSU.
Overall, that makes a 3Tb Fileserver for 4500Euros (including a cheap AMD XP 2400 + 1 Gig ram and Gigabit ethernet), which is quite nice if compared to NAS appliances offered elsewhere.
Of course I don't have the whole collection of utilities to manage the box that comes from major vendors, but Webmin is quite up to the task...

My first attempt at flamebait is duly recognized by at least on slahdot moderator. Yeah !

I know the description is in french, but "HITACHI DESKTAR 7K400 400 Go Serial ATA 7200t 8Mo" is quite understandable, I hope...
"I know they've "announced" them, but they aren't for sale yet."
It seems that chrish (the one that answered your post) have the same delusion:
" IIRC Seagate's 400GB disks aren't scheduled for availability until the fall.
Paper launches suck."
Well, the world is not all Seagate centric, it seems...
"Why are you recommending a solution that you cannot have possibly implemented yourself?"
Well, Joseph, any other witty/uninformed comment on 400Go Sata availability and me implementing (or not, btw) them ???
I mean, this is/., and taking my post at face value would be a leap of faith for someone that has been on slashdot for soooooo long (number 514...nice...).
Maybe you just need to relax. Or read something else than slashdot, and keep informed on what's hot, or, more to the point, on what's out in the market...
depending on the value of your data, you should try having a nice 4*400Go SATA in raid 5 *2, possibly using a distributed file system for redundancy...
Not the cheapest, but fast, simple and saves you the unholy pleasure of having 2-3 DLT boxes to archive/cycle each month...
You already have a linux cluster, so implementing a distributed file system, or even simply a nightly incremental mirror to the target server if you can afford losing one day work/computation...
It would help if you told us what sort of data you work with... from databases and to automated telescope tracking system, both need large amount of storage, but you won't need the same system array for each...
You don't need to go to the Petabyte capacuty but you will find some interesting comments on filesystems, disk virtualisation, 1U rack providers and so on....so a 1 Terabyte rack server is definetly possible...
buy the new set, check that the brand new remote works with yiu old kit, windex (galass cleaner fluid) the old one, put it back in the pack andf return the whole stuff....
If you are more technical and the remote is not a clip on plaqtic case, unscrew, exchange the circuits, ditto...
I'm not sure the moderator had read the article title, called "Impoverish a spammer today"...
Actually there are some people who pay to have me see advertising... They pay newspapers, TVs, websites to show me their wares...
If this scheme goes, I can get money to reveive spam... which is a good tradeoff for me, as for once I get some money, instead of just losing bandwith/time...

I don't know if this goes into Computer Science or Musicology, but people have tried composing music using mathematical equations for quite some time...
Maybe we can get a computer to compose like Mozart and finish his symphonie ?
Something like these people do: "We are a group of students and faculty members in the University of Wisconsin - Madison working on the exciting project of applying artificial intelligence in analyzing and composing music.
In this research, mathematical models will be developed to analyze a given collection of music pieces, represented in MIDI format. In particular, machine learning and artificial intelligence problem solving methods such as neural network, time series prediction, and statistical pattern classification will be used, and to simulate the process of music composition through the results of analysis. The overall objective is to analyze polyphonic music of certain composers, and create new pieces that retain stylistic details which distinguish composers from one another. "

any reason not to use them blades to build a cluster, each blade bay connected to all other, creating a (sic) beowulf or mosix cluster of some sort ?

MDMA was patented in 1913 (patent #274.350) by the German chemical company Merck supposedly to be sold as a diet pill (the patent does not mention any intended use), the company decided against marketing the drug and had nothing more to do with it. The US army experimented with MDMA in 1953, possibly as truth serum, they have not revealed their reasons.
