Comment Re:Soviet space program (Score 3, Insightful) 143

I guess they're just following the Soviet era tried and tested rocket development program. Start by blowing up rockets, and continue until they stop blowing up. Then strap some pilots on top.

This sounds pretty much like the US space program.

It is unfortunate people still have to learn from their mistakes when this has already been done at least twice (CCCP and the US). A person might figure they could afford to hire a couple of engineers who already went through this trial and error.

Comment Don't Let Google Get ALL of the Sponsor Credit. (Score 1) 393

Let us remember that Joby Energy also sponsors this excellent project!

I would also like to add my insight to the previous excellent comments, as this is what allowed me to understand how the car goes faster than the wind:

What is the wind hitting to drive the vehicle forward? Where is the flat spot on the back of the vehicle the wind is pushing against? It is the rear surface of the propeller. The wheels are not driving the propeller to make the car go, they are keeping the relative speed of the air hitting the rear surface of the propeller at the proper speed so the car acts like a sailboat sailing at an angle to the wind.

The fact that this seems counter-intuitive at first makes it a cool problem. With the above, I now feel this makes sense and I have no problem believing it.

I hope this helps other people.

Comment Linux Penguin Born in 1996. (Score 2, Informative) 195

In the early '70s Zappa wrote a song called 'Penguin in Bondage,' an obvious foretelling of the anti-Linux lawsuits and threats from SCO, Microsoft, and other evildoers.

Since Tux came into being in April-May of 1996, it is impossible for Mr. Zappa to have used a penguin reference to suggest anything about Linus in the "early '70s." See: http://www.sjbaker.org/wiki/index.php?title=The_History_of_Tux_the_Linux_Penguin

Submission + - BP Documents Changed Risk Assessment (nytimes.com)

bezenek writes: The quote from the New York Times article speaks for itself.

In April of this year, BP engineers concluded that the casing was â½ÂÅ"unlikely to be a successful cement job,â½Â according to a document, referring to how the casing would be sealed to prevent gases from escaping up the well. The document also says that the plan for casing the well is â½ÂÅ"unable to fulfill M.M.S. regulations,â½Â referring to the Minerals Management Service. A second version of the same document says â½ÂÅ"It is possible to obtain a successful cement jobâ½Â and â½ÂÅ"It is possible to fulfill M.M.S. regulations.â½Â Andrew Gowers, a BP spokesman, said the second document was produced after further testing had been done.


Comment Einstein on Religion (Score 4, Informative) 1123

Some past scientists were in a position where they could speak about religion without fear. Unfortunately, I am not certain that is the case today. Examples from Einstein:

I do not believe in a personal God and I have never denied this but have expressed it clearly. If something is in me which can be called religious then it is the unbounded admiration for the structure of the world so far as our science can reveal it. (Albert Einstein, 1954)

I think this one is of interest given our religious-values/anti-socialist Republican party:

One strength of the Communist system ... is that it has some of the characteristics of a religion and inspires the emotions of a religion.
(Albert Einstein, Out Of My Later Years, 1950)

Comment Re:A lot of commercial real estate sits empty (Score 4, Interesting) 96

Several former office-space buildings are being converted to data centers.

In a regular commute from West San Jose to the Google-plex area in Mountain View I have seen these changes. An existing office building has its windows removed/covered and then a sign goes up showing data center space available or the name of a data warehousing company.

This conversion seems less wasteful as far as materials, but I am not sure how using an existing building compares to building a data-center-specific one for long-term energy efficiencies.

Comment Poor Engineering Communication with Management (Score 2, Insightful) 256

It is disappointing to see Amazon finding out only now that engineers will want to scribble on pages, highlight items, need color, etc.

Amazon employs hundreds if not thousands of engineers, most if not all of which could have told senior executives this.

Unfortunately, many companies in Silicon Valley are being run by executives who have forgotten their companies were built by engineers, and consulting with them once in a while might be useful.

This is not meant to be flame-bait. It is from personal experience and the experiences of other engineers, e.g., Bob Colwell and the inability of Intel to acknowledge the failure of the Itanium processor line before it wasted billions of dollars and several years of engineering time (read Bob's book The Pentium Chronicles for more detail.)

Comment Age of Consent. (Score 1) 114

In the United States, you have to be 18 years old to decide whether or not to possibly damage your future life by smoking. Additionally, except for some serious cases, we have a juvenile court record which is sealed for life, because at one time people recognized a young person might make mistakes which should not affect them when they are adults.

But, as Chris Good points out, Twitter, Facebook, Myspace, Youtube, Web sites, etc. might end up following people for the rest of their lives.

Is it reasonable for a judge being confirmed in 2050 to have this denied via public opinion because he/she had a Facebook video of themselves with a group of friends doing something stupid when they were 15? Or 12?

What about pictures taken via a Web-cam attached to a laptop which was lent to them by their public school?

What about archived video from one of the thousands of cameras placed in public places in most larger US cities?

Comment Re:This is a realization of David Marr's early wor (Score 2, Informative) 64

You know, two people or groups can arrive at the same conclusion, because it was obvious in the first place. And why is it so appropriate? What if the work had been done elsewhere, would that be inappropriate or offensive?

I should have been more specific in my first post.

David Marr's vision book (published in 1982 after his early death in 1980) is considered a seminal work in understanding human visual processing.

Marr was trying to describe how humans see. The new work at MIT is trying to allow computers to see. David Marr would be glad to see the developments, whether at MIT or elsewhere.

Comment This is a realization of David Marr's early work. (Score 4, Interesting) 64

David Marr proposed the idea of a primal sketch as the first stage of converting the two-dimensional image on the retina to a full understanding of what is being looked at. This work culminated in a paper published in 1980 called "Theory of edge detection."

Marr was a faculty member at MIT, so it is appropriate for this work to have been done there.

How about a merit badge for creating Web pages or setting up a Web site. Maybe one for completing a simple self-taught course in a simple language like Java?

The pin is for cubs not scouts, most cubs are still learning to read and write.

When I was a Cub scout, I was programming my TI-57 calculator.

I think we often set the bar too low for our children. New math might have been the worst thing to happen to me academically. I did not find out how devastating it was until I took my first graduate-level mathematics course at the University of Wisconsin.
