Submission + - TSA fiasco at Newark (USA) Airport. (

arktemplar writes: I first found out about this from a friend, turns out it's been tweeted about pretty heavily. Some person slipped through to the sterile zone and the TSA's new and enhanced procedures could do nothing about it. Sadly, they are now causing excessive delays to every one else, planes about to depart have been grounded. I wonder when they'll realise that they need to rethink their strategy for security.

Comment Re:It's not the business model that is broken. (Score 1) 552

Actually while IBM may not do a lot of "pure science". Some of it's breakthroughs in technology have far reaching implications, I'd say something similar with HP. So yes, pure science is not getting the kind of investment it did a while back, yes it could do with more, yes it would help. But I am sure that the kind of work that is being done in pure science nowdays is not the kind that can do with the amount of investment that can be "easily" made.

If there were to be radical shifts - a lot could happen. I guess, but what if scenarios are not particularly useful. Yes we need to do stuff, but the how is much more important. That we need to do stuff has been known for ages.

Also - Europe seems to have more money in pure science - I wonder if some one can get stats about how they have been better off for it. (not a bait - actually curious about the numbers)

- I'm not from any of the above mentioned companies.

Yes, essentially I'd agree with you.

However the thing is this, it's easier to get synthesiseable code in verilog that will correspond to your code directly, if you have experience, that is. However, VHDL seems to be better in my opinion only because it is more structured.

Ok - so the thing is, I've done significant work in both. I kind of liked the fact that VHDL was more structured and readable, however Verilog seems to have more support. Now, apart from this the differences, are mostly in getting synthesiseable results from your code, it's easier to get code match the RTL, like I've already said, if you're working in Verilog, plus synthesisers also have better support for Verilog. However, after getting started on verilog, VHDL is much more attractive in my opinion.

Comment Re:Optical Computing? (Score 1) 251

Well in a way it could be. I'd read the spectrum article some time back, but since I work in the field I can give some insight.

RAM latencies are a huge hit for applications that are based on random access. DRAMs etc. don't actually do random access the way you'd want they access one memory over a large time period, and provide faster access to some successive elements. New processor architectures based on smart caches and intelligent memories could be a lot more useful, basically though a rethinking of processor architecture is involved - in the end electrical and computer engineering is still that : Engineering there will always be tradeoffs.


Submission + - Technology Review -10 Emerging Technologies of 08 (

arktemplar writes: Each year, Technology Review publishes its list of 10 emerging technologies that its editors believe will be particularly important over the next few years. This is work ready to emerge from the lab, in a broad range of areas: energy, computer hardware and software, biological imaging, and more. Two of the technologies cellulolytic enzymes and atomic magnetometers are efforts by leading scientists to solve critical problems, while five surprise modeling, connectomics, probabilistic CMOS, reality mining, and offline Web applications represent whole new ways of looking at problems. And three graphene transistors, nanoradio, and wireless power are amazing feats of engineering that have created something entirely new.

Intel, Micron Boost Flash Memory Speed by Five Times 67

Lucas123 writes "IM Flash Technologies, a joint venture between Intel and Micron, announced they've been able to improve NAND memory and its circuitry in order to boost read/write speeds by five times their current ability. The new 8Gbit single-level cell, high-speed NAND chip will offer 200MB/sec read speeds and write speeds of up to 100MB/sec, which means faster data transfer between devices like solid-state drives and video cards. IM Flash Technologies plans to begin shipping the new chip later this year."

Submission + - Your next clustering solution: PS3 + Linux (

vrrrtk writes: UNICAMP (One of the biggest Brazilian Universities) is using a cluster of PS3 game consoles to perform some calculations about interactions between anesthesia and biological membranes. The Fine Article is in Portuguese. The researcher Monica Pickholz says: "It's the most stable cluster I've seen, it stopped only once because of a failure in the power generator". She also says it's also much cheaper than an performance matching solution using "conventional" servers. The machines run Linux with some clustering technology but she didn't give any details about it. Personally, I'm a little bit surprised to see PS3 working well as server, it has a hell of a processor, but how about I/O performance ? Anyway, I wonder how well they fit in a rack :) [SORRY FOR MY ENGLISH]

Feed Malaysia Decides Not To Force Bloggers To Register (

Following last week's news of a proposal in Malaysia to force bloggers to register with the government, it appears that common sense has won out. There were clearly some politicians who recognized registering bloggers wasn't a very good idea (and was merely a kneejerk reaction to some trouble some politicians had had with critical bloggers). So it's good to see that those politicians effectively got that point across and the plan to force bloggers to register has been rejected. The government still warned bloggers not to publish "rumors" or "offensive remarks" because existing laws will be used against them -- but said that forcing them to actually register was unlikely to be an effective tool.

Feed US Air Force Aims High With Bluespam (

It seems that more and more brands and companies are trying to market themselves via Bluespamming -- sending out unsolicited messages and requests for connections to nearby mobile phones via Bluetooth. Marketers that use the practice, of course, don't call it Bluespam, and see it as a wonderful mechanism to use, even though the vast majority of people that receive the messages aren't interested in them. Now, it's the US Air Force that's turning to Bluespamming, as it plans to use the method to harass mobile phone users at a NASCAR race this weekend. A rep says Bluespamming will help prove the Air Force's high-tech chops to impressionable kids, while somebody from its ad agency says that it will help attract "tech savvy" recruits. Would they say the same things about email spam? Probably not. It's hard to see how annoying just about anybody with a Bluetooth phone in a particular area is a good way to market yourself, and never mind the horrific user experience of delivering content via mobile marketing. Needless to say, it's great to see the US government getting into the spamming business.

Submission + - Neutrinos -- and once again, symmetry is restored!

perturbed1 writes: A Fermilab press release today announced that MiniBooNE's latest results rule out the simple neutrino oscillation interpretation of the LSND experiment. Neutrinos have a tiny amount of mass, required by their oscillations, as observed in solar, atmospheric and reactor neutrino experiments. Combining these results with the LSND experiment's results required the presence of a *fourth* but "sterile" neutrino, breaking the 3-fold symmetry of particle families in the standard model! Symmetry in the particle kingdom has once again been restored. Standard model lives on!
