Comment Re:Steve Jobs on PCB traces (Score 1) 136

Jobs wasn't wrong. If someone posts images of the PCB board of an iPhone 5, everybody will be interested in looking at it. At this period of time, showing a PCB board was just awesome. It looked like the future. Having a beautiful PCB could have been a strong communication point. Maybe Jobs didn't think about that and was just plain wrong at this time, but I'm not convinced the situation is so clear.

Comment Connectors (Score 1) 295

The main reason why 10GbE took time to arrive is simple : connectors are not the good-old RJ45 used for 10Mb, 100Mb and 1GbE. The RJ45 connector is small, cheap and backward compatible. The 10GbE connectors are deep, expensive and not RJ45-compatible, hence cannot be used as a 1GbE port.

10GbE is appearing on servers because the price order is compatible with the expensive and deep connector. It won't appear on commodity motherboards until a smaller connector is designed.

Quoting http://askville.amazon.com/dangerous-car-batteries/AnswerViewer.do?requestId=4217899 :

It is not dangerous to touch the positive terminal with your bare skin, because 12V is not a hazardous voltage.

So the answer is simply : no, it is not dangerous to touch my car battery (though the battery can be dangerous in a lot of other ways).

I learned something today :-)

Submission + - French ISP open new 20 EUR and 2 EUR 3G plans (pcworld.com)

Tymst writes: "French ISP "Free" rocked the local mobile world yesterday, launching 2 new plans.

The first one is a "welfare" plan for 2 EUR (approx. 2.5 USD as of today), granting one hour of outbound calls and 60 SMS (inbound calls and SMS are free). It's actually free for the first 3 millions users of Free's DSL service.

The second and main plan is an all-encompassing plan granting unlimited calls, SMS, MMS, and up to 3GB of data, plus free access to Free's urban wifi network. Free voice communications include international calls to fixed lines in 40 countries, and to fixed AND mobile lines in 4 countries, including the United States and Canada. It cost around 20 EUR (approx. 25.5 USD), or 16 EUR for existing DSL users (approx. 20 USD). Tethering, VoIP and P2P are allowed.

Free has been previously know for sinking DSL plans' prices below 30 EUR in France when it launched its service in 2002. It is speculated that the same thing will happen to mobile plans now, with Free's competitors Orange, SFR and Bouygues Telecom having their backs against the wall."

Submission + - French Mobile company launching all inclusive 20 e

Guybrush_T writes: The French DSL company Free entered today the mobile market, launching an all-inclusive 20 euros/month plan. The plan includes illimited voice calls, including some international destination, such as the US, data (3GB/month), SMS and MMS. Free's offer also includes a 2 euros/month plan with 1 hour voice calls and 60 SMS.

This is a major change for the mobile market in France. Free already changed the internet providers market in France, causing the death of AOL in France.

I'm I the only one who is concerned by the validity of their experiment. The last experiment lets me very dubious.

Imagine you have 3 smileys. They have similar ratings, but for sure there is one you prefer, one you rate 2nd and one you rate 3rd. Now, let's just see the result we would have for each scenario.

Rating of cards 1/2/3 ; 3rd card chosen after initial choice ; 3rd card chosen without initial choice (so just between card 2 and card 3)

1/2/3 ; False (1 chosen on first pass) ; False
1/3/2 ; True (1 chosen on first pass) ; True
2/1/3 ; False (1 chosen on first pass) ; False
2/3/1 ; True (2 chosen on first pass) ; True
3/1/2 ; True (1 chosen on first pass) ; False
3/2/1 ; True (2 chosen on first pass) ; True

Which makes in the first experiment 50% chances of choosing the third card and 66% when we made a previous "preselection". This is approximately the figures children had. Monkeys had lower 3rd card preference, maybe because they prefer to take cards in order.

About the rest of the article, I'm just as dubious. If you choose a product, for sure you rate it better. It's called the cause of you choosing it, not a consequence ...

e Bay ... well maybe. Searching ebay for 3ware escalade cards, you may find some 8 ports or 12 ports IDE controllers. With this, you should be able to connnect 20-40 drives per PC. Hard to find however, but often not so expensive (IDE cards are no more wanted).

After that, the last issue would be the power supply, but I guess this is just simple DIY.

Submission + - Autism symptoms reversed in lab (bbc.co.uk)

DoctorPhish writes: A study, by Massachusetts Institute of Technology, appearing in Proceedings of the National Academy of Sciences shows symptoms of mental retardation and autism have been reversed for the first time in laboratory mice.
The researchers, based at MIT's Picower Institute for Learning and Memory, targeted an enzyme called PAK which affects the number, size and shape of connection between brain cells. They found that inhibiting the enzyme stopped mice with Fragile X Syndrome behaving in erratic ways.
"This implies that future treatment may still be effective even after symptoms are already pronounced" according to Dr Susumu Tonegawa of the research group.
