Comment Three things missing... (Score 4, Interesting) 429

There are still three things missing:
1. Scientists are only counting the laser energy absorbed by the fuel. Not all of the laser energy is absorbed by the fuel.
2. Lasers are not 100% efficient. They take lot more energy than they give out.
3. The generated energy is in the form of heat. Converting it to electrical is not there.

Overall, the efficiency is still less than 1%. Far away from anything usable.

Comment faster upgrades (Score 1) 348

The iPhone-C is a low end device with older hardware. Which means it will become obsolete faster and owners will upgrade in shorter time than iPhone-S owners will. Also, the price difference is not all that high (550 vs 650 USD for iphoneC and iphoneS). Assuming it is $50 cheaper to make iPhone, Apple will recover that in quicker upgrade cycle. Also, it allows Apple to sell iPhone to users who would have gone most likely to Android. In fact, this is the best thing Apple could have done. Apple's recent fall of stock price is because the investors believes that it should have introduced an even lower end device which they didn't. So imaging what would have happened without iPhone-C?

Replace Oracle with Apple or Microsoft and Solaris with Windows. Does MS give free OS upgrade for lifetime on your hardware? What if thirdparty tells you that it is licensed to provide you new versions of OS on your old PC? Oracle is going after those. Each customer gets certain upgrade free and then they have to either buy paid support which include free upgrade or have to pay to get upgrade. I am almost sure, the people in charge of Rimini street were in TomorrowNow which was found guilty of copyright infringement of Oracle software, so I won't call them totally clean.

Comment Some math about water usage by power plant? (Score 2) 189

The study referenced in article says, "And in Texas, regulators denied developers of a proposed 1,320-megawatt coal plant a permit to with draw 8.3 billion gallons". Since USA has about 1100 GW of installed capacity (including hydro), this approximately translates into 7.5 trillion gallons or about 20 billion gallons a day. According to ucsusa, the total withdrawal by power plants is 200 billion gallons a day. So it looks like the old power plants are the main culprits.

Comment dedicated gaming consoles is a niche market (Score 2) 315

Just like PCs became faster and replaced Unix workstations at many places, the low end devices are becoming faster and are threatening the dedicated gaming consoles. Mostly all you need is a good quality controller and you can fairly use high end PC to replace your gaming console. Newer Wi-Fi standards are becoming faster by the day (to easily connect controller to PC) and also virtual controllers like Kinect can easily be ported to PC, so that shouldn't be a bottleneck. The game publishers will be more than willing to support open (relatively speaking) platforms as they don't have to invest huge amount upfront and don't have to pay per game commission to console makers. As of now, I am not planning to upgrade my gaming console. I will wait and watch whether it is worth or not.

Comment The extra information is not free (Score 2) 222

You have to know in advance that the particles are entangled. That extra bit of information is needed. Thus when you measure one particle, you do get that extra bit of information about the other particle. So the information about the other particle is not free but is the direct result of the apriori information about entanglement.

Comment Limited preemptive screening (Score 1) 345

Although pre-screening is not economically feasible, limited pre-emptive screening might be. If the view count exceeds 100, it should screen. Besides, the post summary says "72 hours of content every min". This is irrelevant, when you only do first few seconds of screening of each video. A more important measure would be number of videos a min. Also, if a video is uploaded by user with a nice record, then only a small sample of those users' video should be screened. Further automated analysis can analyze the quality of video. If the quality is poor, its effect on reducing sale of actual video is minor and can be removed as well. I don't have any statistics, but based on my viewing habits, this can eliminate need to screen > 98% of videos and the cost can fall to less than 1B. Still large, but not significantly lower.

Comment You need just one equation (Score 1) 655

Frankly, you need just one equation which is known for quite long time: Obesity is inversely proportional to fraction of income spent on food. America has this fraction very low compared to most nations (even richer nations where people spent more money on less but more expensive food items). In many poor countries, this ratio is greater than 40%. In America, it is less than 10%.

Comment Why so much sensationalization? (Score 2) 569

"The disease is sexually transmitted, endemic in the sexually active, can cause genital warts in both men and women, and is the primary cause of cervical cancer, which kills hundreds of thousands of women globally each year."

Let us look at the figures at wiki. 4800 women died in US of cervical cancer. 70% of these are caused by HPV and the vaccines are 90% effective. It means that if everyone is vaccinated, it will prevent about 3000 deaths. Remember CDC is recommending for US men and women and has no effect on global deaths which is around 250k/yr of which 70% are due to HPV, which is about 175k. That figure does not qualify as "hundreds of thousands".

Also, with the cost ranging in the region of $100-200 and effectiveness of 4-6 years, this is one of the most expensive preventive medicines ever.

Comment Android as an open platform is a myth (Score 2, Interesting) 328

Android only uses Linux based kernel. How does it make it open. You can't update anything on your Android phone without the permission from carrier/manufacturer/google. Google hasn't released latest Andrioid source code, not that it would help user in any way. You can't use gps on Android phone without giving google all your location information. The truth is, apart from the fact that you can download uncertified app on google android, you can't do anything more that what you can do on competing platform. I don't think this makes it any more open than other offerings.
