Comment Airtame (Score 1) 128 128

What you really want is Airtame ( Anything that appears on your screen is sent to the TV. And it works as it's own wifi access point. The hardware is solid but the software is still under development. Worth waiting for I think. It will eventually work on Linux plus the other usual suspects, including IOS and Android.

Comment Third Dimension (Score 5, Interesting) 1150 1150

We are accustomed to living in a 2D world (unless you live in a tall apartment in NY... and even then) but drones add a third dimension that we are not used to. I think the FAA has been far too lax in allowing drones to operate in unrestricted space and in not applying radio controlled airplane regulations to drones. Already we have drones crashing into buildings, falling on people, endangering commercial and emergency response airplanes etc, etc)

A good starting point would be to recognize the airspace above private property as part of the property, up to the level allowed to commercial aircraft. That would mean that drones could only fly above designated land surfaces.

If we are talking MLC NAND, you are off by a factor of 10.

But since the XPoint cells are individually addressable bit by bit, the comparison is probably to SLC, in which case the relevant number of P/E cycles for XPoint would be 10E8 and you are off by a factor of more than 33,000.

Comment Ram replacement? (Score 4, Interesting) 170 170

There has been some discussion that 3D XPoint might be a replacement for RAM in mobile devices because it is "ram-like" in speed and low power due to the fact that it's non-volatile. If this can replace RAM and NAND in phones and tablets, it will be a major milestone in the history of computing.

I don't usually bother to make negative comments, but this is too much. If their claim is true, then the memory would cost the same per bit of memory and 8 to 10 times as much per unit of volume. Got it? And it is not really important how much it costs per unit volume. It's just important that the memory will not take up much space. You really need to slow down and work on your critical thinking skills. /rant

What Snowden did was technically illegal, but he was exposing previous illegal acts by the government, so he should be pardoned on that basis. Snowden has not been charged (yet) under the espionage act because the possibility of the death penalty would block his extradition from most European countries where he might seek asylum.

"He should come home to the United States, and be judged by a jury of his peers — not hide behind the cover of an authoritarian regime." That's just ridiculous. He would never see a public courtroom but would be tried in a secret "patriot act " court. I think the authoritarian regime is right here.

This is not the America I grew up in. This is disgraceful.

Geography is logically an extension of history and is covered in my list. Arts and foreign language are probably more important than computer science at the K-12 level. I'm really in favor of including all of these subjects, but there is a priority based on universal need for the knowledge, i.e. a critical path.

If you want to include computer science without deleting existing core subjects, it will cost more money and class time. Are you willing to pay more in taxes to support schools? Are you willing to extend the class day and academic year so there is time to teach all these subjects? I am willing to accept those changes but to add comp sci without those changes will be destructive.

Comment Critical thinking (Score 2) 132 132

The first goal of K-12 education should be to teach critical thinking skills. Kids need to learn to think logically and to understand the meaning of a critical path. The second goal should be to teach English and communication skills. Third comes history and civics, the knowledge to become a functioning citizen. Fourth would be a basic grounding in math and science.

        the schools manage to do all those things and still have money and class time left over.... fine....

        it makes sense to focus on computer science as a "core academic subject".

Comment There's no There there. (Score -1, Troll) 248 248

There is no defensible reason for humans to go to the moon. I'd be much more interested in a study of the cost and time frame of a colonization mission (one way) to Mars. That is the next home of mankind. Any other mission in space can be achieved faster and more economically by machines.
