Submission + - Turing Manuscript Sells for $1 Million

itwbennett writes: A 56-page notebook manuscript by Alan Turing, the English mathematician considered to be the father of modern computer science, was sold at auction Monday for $1.025 million. Turing apparently wrote in the notebook in 1942 when he was working in Bletchley Park, England, trying to break German military code.

Submission + - This Is Big: A Robo-Car Just Drove Across the Country (wired.com)

Press2ToContinue writes: AN AUTONOMOUS CAR just drove across the country.

Nine days after leaving San Francisco, a blue car packed with tech from a company you’ve probably never heard of rolled into New York City after crossing 15 states and 3,400 miles to make history. The car did 99 percent of the driving on its own, yielding to the carbon-based life form behind the wheel only when it was time to leave the highway and hit city streets.

This amazing feat, by the automotive supplier Delphi, underscores the great leaps this technology has taken in recent years, and just how close it is to becoming a part of our lives. Yes, many regulatory and legislative questions must be answered, and it remains to be seen whether consumers are ready to cede control of their cars, but the hardware is, without doubt, up to the task.

Submission + - Ebola virus found to be defective zombie virus (wikipedia.org)

kallen3 writes: The Center for Disease Control has announced that the Ebola virus originated as a zombie virus but has mutated to it's present form. What is a concern to many epidemiologists though is that there are some indications that not all strains of the zombie virus has mutated into a form of Ebola. Dr. Moreau of the CDC says that there are indications in local folklore that there are zombies wandering the back country in those countries currently affected by the Ebola strain of the zombie virus. The current concern that Dr. Moreau has is that those infected by the Ebola strain being brought back to their home country may spread the Zombie virus if the Ebola strain mutates back to it's original form.

but their creed (or motto?) was "if somebody dies, leave them behind"

Whether it be a car breaking down or somebody actually dead - they once said (several years back) that they had all sworn to keep going !!

However - Jeremy was kind of the leader. Hammond maybe could do it - would be strange. If it were me - I'd bail because I'd just "cock it up." Wouldn't want to be around as it fell down. Get out while on the top.

I saw an interview yesterday with Capt Slow on his front porch. He acknowledged the media reports and then said "If you'll excuse me I have a LaFerrari to list on eBay" and left.

Comment Re:Check their work or check the summary? (Score 1) 486

Yes thank you. This is a classic mistake that many first time programmers make. Years ago somebody was comparing the speed of C++ over VBScript/IIS over Java for writing Web pages back to a browser. They too came to a similar conclusion - and also made the same mistake.

When writing to disk - the data is written once. The algorithm for in memory is not doing the same thing. It is allocating a new buffer - copying all data to said new buffer - and finally adding data to the end. If one compared the I/O of the two program executions the "in-memory" version would have many times MORE I/O.

Doing this:
    Loop N.{ x = x + newValue}
    Write(x)
Will always be slower than
      Loop N.{ Write(newValue) }

In C# and I think Java - there is an object called StringBuffer - and is intended for this kind of workload. The first thing I learned in data structures class was how to expand buffers using different algorithms and pro/con of each (heap design for instance, buddy system).

Plus - O(n) is not created equal. :-P

Submission + - How long would it take you to fall through Earth? (sciencemag.org)

sciencehabit writes: Suppose you dug a tunnel through the center of Earth, jumped in, and let gravity pull you through. How long would it take you to reach the other side of the planet? For decades, physics students have been asked to calculate that time and have been taught that the correct answer is 42 minutes. Now, a more realistic analysis has lopped 4 minutes off that estimate.

Comment I saw it on TV - must be true (Score 2) 224

There are whole TV shows written around this very idea. One can simply observe mannerisms and jump to fully detailed truths about people. These writers must have something to base these plots lines on - they couldn't publish a TV show if it weren't true ...right?!

So why shouldn't a TSA executive use the idea, sort out the details, get the best scientists/consultants to provide the truthiness, and create the real thing. I mean - isn't this what the Lone Gunmen proposed in X-Files? Secret science that was all true but hidden from us normal folks via conspiracy theories?!

Junk Science is labeled by people who refuse to think outside the box. Go talk to the Creationists - they know what's going on.

Submission + - Jupiter destroyed 'super-Earths' in our early solar system (sciencemag.org)

sciencehabit writes: If Jupiter and Saturn hadn’t formed where they did—and at the sizes they did—as the disk of dust and gas around our sun coalesced, then our solar system would be a very different and possibly more hostile place, new research suggests. Computer models reveal that in the solar system’s first 3 million years or so, gravitational interactions with Jupiter, Saturn, and the gas in the protoplanetary disk would have driven super-Earth–sized planets closer to the sun and into increasingly elliptical orbits. In such paths, a cascade of collisions would have blasted any orbs present there into ever smaller bits, which in turn would have been slowed by the interplanetary equivalent of atmospheric drag and eventually plunged into the sun. As Jupiter retreated from its closest approach to the sun, it left behind the mostly rocky remnants that later coalesced into our solar system’s inner planets, including Earth.

Submission + - Test trial to use computer servers to heat homes (ap.org) 1

MarcAuslander writes: Eneco, a Dutch-based energy company with more than 2 million customers, said Tuesday it is installing "e-Radiators" — computer servers that generate heat while crunching numbers — in five homes across the Netherlands in a trial to see if their warmth could be a commercially viable alternative for traditional radiators.
