US Air Force to Launch Military Orbital Spaceplane
At first sight, it looks like the US military is starting to feel the heat of the May 2010 deadline for the space shuttle program—which will limit their capacity to service military satellites as well as their secret orbital base, with all those nuclear heads and chemical lasers capable of blowing up Teheran in a millisecond.

Fragments of the Antikythera Mechanism, an ancient astronomical computer built by the Greeks around 80 B.C. It was found on a shipwreck by sponge divers in 1900, and its exact function still eludes scholars to this day.
After a closer examination of a surviving marvel of ancient Greek technology known as the Antikythera Mechanism, scientists have found that the device not only predicted solar eclipses but also organized the calendar in the four-year cycles of the Olympiad, forerunner of the modern Olympic Games.
But you would say, computers can't be mechanical devices. Right?

There are several US banks that are now in big trouble
US banks have written down $450 billion in bad housing loans.
The revelation from NAB means that they will now certainly need to take provisions to $1,000 billion. But write-downs of $1,300 billion and perhaps even more are on the cards.

Fewer than one in 11 of the PCs being used in large or very large enterprises runs Windows Vista,
Petavision project using petaflops supercomputer
Is artificial vision just around the corner?
Roadrunner has a unique hybrid design comprised of nodes containing two AMD OpteronTM dual-core processors plus four PowerXCell 8iTM processors used as computational accelerators. The accelerators are a special IBM-developed variant of the Cell processors used in the Sony PlayStation 3.
Are PS3 bundles better for that task than the NVIDIA GC performance monsters ?
Or perhaps FPGA?
People actually like Microsoft Vista, though they still don't know that :)

David Kaminski DNS attack in detail
- Reliable DNS Forgery in 2008: Kaminskyâ€™s Discovery
- from Matasano Chargen by ecopeland
- The cat is out of the bag. Yes, Halvar Flake figured out the flaw Dan Kaminsky will announce at Black Hat.
- Pretend for the moment that you know only the basic function of DNS â€” that it translates WWW.VICTIM.COM into 126.96.36.199. The code that does this is called a resolver. Each time the resolver contacts the DNS to translate names to addresses, it creates a packet called a query. The exchange of packets is called a transaction. Since the number of packets flying about on the internet requires scientific notation to express, you can imagine there has to be some way of not mixing them up.
- Bob goes to to a deli, to get a sandwich. Bob walks up to the counter, takes a pointy ticket from a round red dispenser. The ticket has a number on it. This will be Bobâ€™s unique identifier for his sandwich acquisition transaction. Note that the number will probably be used twice â€” once when he is called to the counter to place his order and again when heâ€™s called back to get his sandwich. If youâ€™re wondering, Bob likes ham on rye with no onions.
- If youâ€™ve got this, you have the concept of transaction IDs, which are numbers assigned to keep different transactions in order. Conveniently, the first sixteen bits of a DNS packet is just such a unique identifier. Itâ€™s called a query id (QID). And with the efficiency of the deli, the QID is used for multiple transactions.
- Until very recently, there were two basic classes of DNS vulnerabilities. One of them involves mucking about with the QID in DNS packets and the other requires you to know the Deep Magic.
- First, QIDs.
- Bobâ€™s a resolver and Alice is a content DNS server. Bob asks Alice for the address of WWW.VICTIM.COM. The answer is 188.8.131.52. Mallory would like the answer to be 184.108.40.206.
- It is a (now not) secret shame of mine that for a great deal of my career, creating and sending packets was, to me, Deep Magic. Then it became part of my job, and I learned that it is surprisingly trivial. So put aside the idea that forging IP packets is the hard part of poisoning DNS. If Iâ€™m Mallory and Iâ€™m attacking Bob, how can he distinguish my packets from Aliceâ€™s? Because I canâ€™t see the QID in his request, and the QID in my response wonâ€™t match. The QID is the only thing protecting the DNS from Mallory (me).
- QID attacks began in the olden days, when BIND simply incremented the QID with every query response. If you can remember 1995, hereâ€™s a workable DNS attack. Think fast: 9372 + 1. Did you get 9372, or even miss and get 9373? You win, Alice loses. Mallory sends a constant stream of DNS responses for WWW.VICTIM.COM. All are quietly discarded â€”- until Mallory gets Bob to query for WWW.VICTIM.COM. If Malloryâ€™s response gets to your computer before the legitimate response arrives from your ISPâ€™s name server, you will be redirected where Mallory tells you youâ€™re going.
- Obvious fix: you want the QID be randomly generated. Now Alice and Mallory are in a race. Alice sees Bobâ€™s request and knows the QID. Mallory has to guess it. The first one to land a packet with the correct QID wins. Randomized QIDs give Alice a big advantage in this race.
- But thereâ€™s a bunch more problems here:
- If you convince Bob to ask Alice the same question 1000 times all at once, and Bob uses a different QID for each packet, you made the race 1000 times easier for Mallory to win.
- If Bob uses a crappy random number generator, Mallory can get Bob to ask for names she controls, like WWW.EVIL.COM, and watch how the QIDs bounce around; eventually, sheâ€™ll break the RNG and be able to predict its outputs.
- 16 bits just isnâ€™t big enough to provide real security at the traffic rates we deal with in 2008.
- Your computerâ€™s resolver is probably a stub. Which means it wonâ€™t really save the response. You donâ€™t want it to. The stub asks a real DNS server, probably run by your ISP. That server doesnâ€™t know everything. It canâ€™t, and shouldnâ€™t, because the whole idea of DNS is to compensate for the organic and shifting nature of internet naming and addressing. Frequently, that server has to go ask another, and so on. The cool kids call this â€œrecursionâ€.
- Responses carry another value, too, called a time to live (TTL). This number tells your name server how long to cache the answer. Why? Because they deal with zillions of queries. Whoever wins the race between Alice and Mallory, their answer gets cached. All subsequent responses will be dropped. All future requests for that same data, within the TTL, come from that answer. This is good for whoever wins the race. If Alice wins, it means Mallory canâ€™t poison the cache for that name. If Mallory wins, the next 10,000 or so people that ask that cache where WWW.VICTIM.COM is go to 220.127.116.11.
- Then thereâ€™s that other set of DNS vulnerabilities. These require you to pay attention in class. They havenâ€™t really been talked about since 1997. And theyâ€™re hard to find, because you have to understand how DNS works. In other words, you have to be completely crazy. Lazlo Hollyfeld crazy. Iâ€™m speaking of course of RRset poisoning.
- DNS has a complicated architecture. Not only that, but not all name servers run the same code. So not all of them implement DNS in exactly the same way. And not only that, but not all name servers are configured properly.
- I just described a QID attack that poisons the name serverâ€™s cache. This attack requires speed, agility and luck, because if the â€œrealâ€ answer happens to arrive before your spoofed one, youâ€™re locked out. Fortunately for those of you that have a time machine, some versions of DNS provide you with another way to poison the name serverâ€™s cache anyway. To explain it, I will have to explain more about the format of a DNS packet.
- DNS packets are variable in length and consist of a header, some flags and resource records (RRs). RRs are where the goods ride around. There are up to three sets of RRs in a DNS packet, along with the original query. These are:
- Answer RRâ€™s, which contain the answer to whatever question you asked (such as the A record that says WWW.VICTIM.COM is 18.104.22.168)
- Authority RRâ€™s, which tell resolvers which name servers to refer to to get the complete answer for a question
- Additional RRâ€™s, sometimes called â€œglueâ€, which contain any additional information needed to make the response effective.
- A word about the Additional RRâ€™s. Think about an NS record, like the one that COMâ€™s name server uses to tell us that, to find out where WWW.VICTIM.COM is, you have to ask NS1.VICTIM.COM. Thatâ€™s good to know, but itâ€™s not going to help you unless you know where to find NS1.VICTIM.COM. Names are not addresses. This is a chicken and egg problem. The answer is, you provide both the NS record pointing VICTIM.COM to NS1.VICTIM.COM, and the A record pointing NS1.VICTIM.COM to 22.214.171.124.
- Now, letâ€™s party like itâ€™s 1995.
- Download the source code for a DNS implementation and hack it up such that every time it sends out a response, it also sends out a little bit of evil â€” an extra Additional RR with bad information. Then letâ€™s set up an evil server with it, and register it as EVIL.COM. Now get a bunch of web pages up with IMG tags pointing to names hosted at that server.
- Bob innocently loads up a page with the malicious tags which coerces his browser resolve that name. Bob asks Alice to resolve that name. Here comes recursion: eventually the query arrives at our evil server. Which sends back a response with an unexpected (evil) Additional RR.
- If Aliceâ€™s cache honors the unexpected record, itâ€™s 1995 â€”- buy CSCO! â€”- and you just poisoned their cache. Worse, it will replace the â€œrealâ€ data already in the cache with the fake data. You asked where WWW.EVIL.COM was (or rather, the image tags did). But Alice also â€œfound outâ€ where WWW.VICTIM.COM was: 126.96.36.199. Every resolver that points to that name server will now gladly forward you to the website of the beast.
- Itâ€™s not 1995. Itâ€™s 2008. There are fixes for the attacks I have described.
- Fix 1:
- The QID race is fixed with random IDs, and by using a strong random number generator and being careful with the state you keep for queries. 16 bit query IDs are still too short, which fills us with dread. There are hacks to get around this. For instance, DJBDNS randomizes the source port on requests as well, and thus wonâ€™t honor responses unless they come from someone who guesses the ~16 bit source port. This brings us close to 32 bits, which is much harder to guess.
- Fix 2:
- The RR set poisoning attack is fixed by bailiwick checking, which is a quirky way of saying that resolvers simply remember that if theyâ€™re asking where WWW.VICTIM.COM is, theyâ€™re not interested in caching a new address for WWW.GOOGLE.COM in the same transaction.
- Remember how these fixes work. Theyâ€™re very important.
- And so we arrive at the present day.
- Letâ€™s try again to convince Bob that WWW.VICTIM.COM is 188.8.131.52.
- This time though, instead of getting Bob to look up WWW.VICTIM.COM and then beating Alice in the race, or getting Bob to look up WWW.EVIL.COM and slipping strychnine into his ham sandwich, weâ€™re going to be clever (sneaky).
- Get Bob to look up AAAAA.VICTIM.COM. Race Alice. Aliceâ€™s answer is NXDOMAIN, because thereâ€™s no such name as AAAAA.VICTIM.COM. Mallory has an answer. Weâ€™ll come back to it. Alice has an advantage in the race, and so she likely beats Mallory. NXDOMAIN for AAAAA.VICTIM.COM.
- Aliceâ€™s advantage is not insurmountable. Mallory repeats with AAAAB.VICTIM.COM. Then AAAAC.VICTIM.COM. And so on. Sometime, perhaps around CXOPQ.VICTIM.COM, Mallory wins! Bob believes CXOPQ.VICTIM.COM is 184.108.40.206!
- Poisoning CXOPQ.VICTIM.COM is not super valuable to Mallory. But Mallory has another trick up her sleeve. Because her response didnâ€™t just say CXOPQ.VICTIM.COM was 220.127.116.11. It also contained Additional RRs pointing WWW.VICTIM.COM to 18.104.22.168. Those records are in-bailiwick: Bob is in fact interested in VICTIM.COM for this query. Mallory has combined attack #1 with attack #2, defeating fix #1 and fix #2. Mallory can conduct this attack in less than 10 seconds on a fast Internet link.

World's First Two-Watt PC
Finally, a truth on decent hardware
The CherryPal desktop consumes just two watts of power, compared to the 114 watts of power used by the average desktop machine, delivering a 98 percent decrease in energy consumption. In addition, it also uses 80 percent fewer components, dramatically reducing the amount of resources it takes to manufacture a PC. And because there are no moving parts, the CherryPal desktop can last a decade or longer, eliminating the need to replace a computer every two to three years.

Survival of the Machines through shared reality
In the real world, a few researchers are working toward a moment that feels inspired by such science fiction: a tipping point when smart computers themselves become capable of creating smarter computers, at a speed and in a direction we cannot predict.
Professor Jeremy Cooperstock, who teaches a course in Artificial Intelligence at McGill University, sits in a "shared reality" environment in a university lab. Shared reality is a twist on virtual reality, involving interactive virtual environments that can be shared by users in different locations, and can also interact with the real world.
The end of more than Moore era !
"There are three forces that are converging as growth enablers for chips—the Internet, connectivity and Moore's Law,"
"After 22nm the result of further scaling is more power consumption, more costly [devices] and slower operation"
Gulp. Seems only 2 scaling generation more are left to invincible manufacturerIntel. Than in hardware we will face too the same problem like with Microsoft Vista. Expensive resource hogging.
Singer reminded the audience that "it takes 10 years for innovative technologies to be entrenched in volume production from the time they were researched and developed.
Actually, one unblocked road is left. It is called 3D device integration, but the industry is not ready at all. Nor it will be in time.

Mars Space Odyssey 2011: 10 Petaflops computer at the University of Illinois
We've got documents showing IBM going after a 10 petaflop system (peak) comprised of 38,900 eight-core Power7 chips with each chip running at 4.0GHz. This monster will have an astonishing 620TB of memory and 5PB/s of memory bandwidth. To be used at the University of Illinois by the year 2011.
SF writer Sir Arthur Clarke had a vision of HAL9000 Psycho badhardware supercomputer (No. 13th in Hollywood 100 years list of villains, by the way Count Dracula is only no. 33 at the same list) in his legendary novel Space Odyssey 2010.
Unnecessary to say, HAL9000 has been too designed and operated at the University of Illinios.
"I am a HAL 9000 computer. I became operational at the H.A.L. plant in Urbana, Illinois on the 12th of January 1992. My instructor was Mr. Langley, and he taught me to sing a song. If you'd like to hear it I can sing it for you. "
HAL, open the doors, please. !
Everything on Earthly bad hardware you can find free of charge at BADHARDWARE. However, human analogs for Clarke's higher mental supercomputer's malfunctions like in the legendary Odyssey 2001, you can find of course at the open the doors institution of closed type.
Let me remind you in th end that in those hippie years the very idea of possible terrorism threats still wasn't clearly exposed to broad, mainly cinema public)

The secret of Intel's Core duo bus efficiency finally discovered in detail !
MSI officially announces first 12.1-inch Puma kitties
The second one packs a bit more power as it is based on ATI's RX781+SB700 chipset. This one will come with ATI Radeon HD 3450 with 256MB of GDDR3 memory. The rest of the specs are the same as on the PR211 model. Both of these models are coming with a 12.1-inch TFT screen capable of showing 1280x800 resolution.
They are both delivering speedy scratches NOW, immediately. Atom power seems pale compared with this. :)
Obama wins landslide 4: 1 !, well for now among the Internet people .
Expected democratic presidential nominee Barack Obama apparently reaches a far greater Internet audience than the Republican nominee, John McCain. According to a survey released by Nielsen Netratings, Obama’s website counted 2.3 million unique visitors in June while John McCain’s site was the destination of only 563,000 unique visitors, market research firm Nielsen Netratings said today (see the picture above).

Caller: "If you've got a couple of minutes perhaps you could find out what it is? It's been there at least half an hour and it's still there."
Control: "It's been there for half an hour. Right. Is it actually on the mountain or in the sky?"
Caller: "It's in the air."
Control: "I will send someone up there now to check it out."
After the police patrol car arrives, the script reveals the exchange between the control room and the police officer sent to the scene.
Control: "Alpha Zulu 20, this object in the sky, did anyone have a look at it?"
Officer: "Yes, it's the moon. Over."
