My graduation project team and I are facing a sort of a problem. The project is concerned with aerodynamics, we have 4 BMW (scale 1:18) car models and we are putting them in a wind tunnel.
We are Using a Hampden wind tunnel. The problem we are facing these days is fixing the car model on a plat
According to the NY Times, a former Apple employee has told them that that "Steve is extremely happy with the new tablet." Guess he might not kill this one then.
I don't even want to speculate what about this tablet makes Steve so happy or about what will be so surprising about interacting with it. I just want to interact with one. Period. [NY Times]
Hello, I have a 2001 Chevy S-10, with a 4.3 litre votec engine. I've always had problems with security lite coming on at an particular time.

Researchers at the Los Alamos National Laboratory have managed to accidentally cause $3 million of damage as they blew up one of their own buildings using a large-bore powder gun, a weapon which acts like a Civil War cannon. Updated.
According to Project on Government Oversight's Senior Investigator, Peter Stockton, this incident "is a new twist in the long history of screw-ups by Los Alamos." I can't really blame him for saying that when testing a gun results in several million dollars of structural damage, propels doors away from the building, and leaves pieces of the weapon spread out on the ground outside. Geez.
Let's look at the positive side of this though. The gun was a mess, but they discovered a heck of a bomb here, no? [Pogo via Wired]
Update: Wired reports that they've received an email from National Nuclear Security Administration spokesman Damien LaVera which implies that what we've first heard might not be the exact story:
Here are the facts: On December 16, Los Alamos conducted a standard proof test on a new design for a catch tank in the target chamber for one of our large bore powder guns (LBPG). These types of experiments are routine and responsible. The LBPG is used to conduct measurements of material properties at pressures needed for understanding nuclear weapons performance. During this particular test, unexpected explosive damage occurred and, because that damage could result in $1 million in damages, an investigation was automatically triggered. That investigation will seek to identify the cause of the incident and any changes in procedures that might be required. NNSA, Los Alamos, and all of our facilities take their commitment to safety very seriously. It is important to note that no personnel were injured from this event, no hazardous or radioactive materials were involved, and that lab's incident response mechanisms appear to have performed as intended.
Offering unusually good philanthropic returns — meaning greater odds of a positive Singularity and lesser odds of human extinction — the Singularity Institute has launched a new challenge campaign. The sponsors, Edwin Evans, Rolf Nelson, Henrik Jonsson, Jason Joachim, and Robert Lecnik, have generously put up $100,000 of matching funds, so that every donation you make until February 28th will be matched dollar for dollar. If the campaign is successful, it will raise a full $200,000 to fund SIAI's 2010 activities.
Clearly these are important topics, and overwhelmingly deserve to be funded. Definitely worth a look.
Verizon's been defending its ridiculous $350 smartphone early termination fee to the FCC, but those folks aren't having any of it. In fact, the five-person committee dealing with the issue thinks Verizon's answers are "unsatisfying and, in some cases, troubling."
Mignon Clyburn, a member of that FCC committee, wrote a letter with a laundry list of issues she has with Verizon's treatment of its customers and makes it a point to say that she looks "forward to exploring this issue in greater depth with [her] colleagues in the New Year." Yikes. Not such great news for Verizon, but it could lead to some good for consumers. [FCC via Engadget]
Tis the time to be amazed: A 38-year-old man has regained vision in his blind eye thanks to a new stem cell therapy. It won't cure all blind people, but it's a giant leap. Here's how it works.
Englishman Russell Thurnbull got attacked with ammonia 15 years ago during a street fight. As a result, he got an extremely painful condition called Limbal Stem Cell Deficiency, which resulted in blindness in one eye. After much medication, he became a lab rat for all kinds of treatments until a team from Newcastle's North East England Stem Cell Institute got the miraculous cure he was waiting for.
First, the team took a minuscule sample of stem cells from his healthy eye's cornea. This millimeter square of cells was placed on a amniotic membrane, which was placed inside a liquid made from his blood, glucose, insulin, and hydrocortisone. The cells will grow in that solution until taking all over the membrane, which then is used to replace the damaged cornea.
The result: He completely gained eyesight after only eight weeks of the operation. It is not Christopher Reeve walking, but if this is not the future ringing the doorbell, right here, right now, I don't know what it is. [Channel 4]
Keith's note: IV&V had an unexpected visit from NASA's Chief of Safety and Mission Assurance Officer Bryan O'Connor today. He relieved Butch Caffall immediately of his duties as Facility Director of NASA IV&V and re-assigned him to NASA HQ "to work some technical issues for NASA starting early in January" according to an internal memo. Greg Blaney is acting IV&V Program Manager and IV&V Facility Director. IV&V employees had been expecting something to happen but this action was more abrupt and sudden than had been expected.
According to a NASA IV&V engineer: "The immediate re-assignment of the NASA IV&V director represents the end of modeling of NASA projects as part of our IV&V analysis. We have endured four years of spending IV&V funds on, what has been from the onset, an R&D effort to create a new method of doing IV&V using an independently built system reference model (UML based) of a space vehicle design based on Project artifacts. Its been costly in dollars and in performance. This R&D has taken countless man-hours away from our directive to find issues/problems with S/C FSW development."
"Critics of NASA IV&V would argue that we have never been effective or productive to justify the $35M annual budget. The argument I make is that the intent of IV&V is not as a lead effort to debug and assure mission success but rather as a final step in assuring mission success. We receive documents not in draft but primarily first and later revisions after peer review, V&V and/or I&T have analyzed artifacts. This is the ideal circumstance. We do receive, in fact, drafts and documents lacking project V&V and under such circumstances we do find more issues.
But the bottom line is that we cannot be expected to find numerous high severity issues or many issues overall. On this basis, the NASA IV&V funding level is well spent. NASA IV&V has delivered high severity issues to many projects that have saved development time and/or prevented serious events from unfolding during a mission's operation. Additionally, IV&V has functioned also as a watchdog and has kept Project developers, V&V and I&T more on their toes. This latter point is a hard to measure return on investment but it is significant. One other question that arises is whether, IV&V needs to reside off-site, as presently, and remote from all Projects. It is not necessary to be remotely situated to maintain independence of the V&V.
However, I strongly disagree that NASA IV&V should be disbanded, removed from WV and distributed to NASA centers. The present IV&V facility has acquired an excellent group of analysts who, if given a proper directive, method and also cooperation from the Projects they support, will deliver the analysis and issues that cost-effectively raises the mission assurance of every project they review. Our existence is the result of the efforts of our Senator and Congressman to bring technology jobs to West Virginia. The nation's capital metropolitan area, FL, TX, CA, AL, MS, OH have benefited greatly from the presence of NASA Centers.
NASA IV&V remains a critical core group in the Technology Park developing in Fairmont and it is a very small price to pay to assist the West Virginia economy. Given the proper support from HQ and from the Projects we assist, the existing IV&V personnel in Fairmont can function effectively and fulfill the directive and fill the needs that have were found lacking after review of the Challenger and Columbia disasters and the string of Mars mission losses in the 1990s. As with the question of continued funding of major NASA Centers that have been on the chopping block over the years, politics is a major factor. The whole NASA budget is only ~1.4% of the Federal Budget.
NASA IV&V is 2/10ths of 1% of the NASA budget - a small sum expended on added assurance. Added expenditures and over-runs due to poor project management and design errors amounts to on the order of 100 times more than the cost of the IV&V budget. Our divulges involving modeling do not represent a catastrophic event or loss of mission. We argue that our mission be righted and our funding maintained. The engineers in Fairmont very eager to make needed changes."

Ganguly is dead. Died in his sleep on the stoop of the shop that gave him the ok for that. So happy for him and happy for me that I was able to have a laugh and help him out before he kicked it. Died in new clothes and with money in his pocket. If I'd been here we would have celebrated at Manikarnika ghat but instead the electric place got the body. He'd be pleased anyway lived right till the e
