Space Station Solar Arrays
NASA – (3 April 2013) — This close-up picture of a Zvezda Service Module array, reflecting bright rays of the sun, thus creating an artistic scene, was photographed on April 3 by one of the Expedition 35 crew members as part of an External Survey from International Space Station windows that was recently added to the crew’s task list.
By Erik Wasson – Debt-ceiling politics are back in full force.
House Democrats on Monday blasted Republicans for moving forward with legislation to prioritize debt payments in the event that the nation’s debt ceiling is exceeded. They said the GOP maneuver is a clear sign that a repeat of the brutal 2011 fiscal confrontation is looming.
The $16.8 trillion national borrowing limit has been suspended until May 19. Once the limit goes back into effect, the Treasury Department will have a matter of weeks before it can no longer avoid being unable to meet some payment obligations. more> http://tinyurl.com/d3qejvd
By Colin Walls – The first real debugger for embedded software, which enabled developers to see what was happening in high level language terms, was XRAY Debugger, which was released by Microtec Research in late 1986.
The timing of this release made sense, as it was just beginning to be feasible for each programmer to have their own computer. Before that, programming was largely done on paper in the first instance, and only entered on to a computer when access was available. This meant that programmers were quite careful and would “dry run” their code by hand before going anywhere near a computer. I have a sneaking suspicion that there were a few less bugs in those days, simply because time on a computer was precious and more thought was given to the code before it was entered. Nowadays, the approach of just throwing code at a debugger is all too common. more> http://tinyurl.com/dy9ua97

By Farhad Manjoo – Bitcoin, of course. Bitcoin is a “digital currency” invented in 2009 by a cryptographic expert who went by the pseudonym Satoshi Nakamoto, but whose true identity remains unknown. It exists only in computers, minted at a regular rate by a network of machines around the world, and its value isn’t regulated by any government. The currency, like its creator, clings to the shadows. Bitcoins are like cash in that they aren’t tied to your identity, and transactions made with Bitcoins are irreversible and untraceable. But they’re like credit cards in that they aren’t physical.
After taking its $21.51 processing fee, the firm transferred my $1,000 to Bitfloor, one of the many online Bitcoin exchanges where people trade Bitcoins for cash. I immediately put in a purchase order, and within seconds the deal was done. I was the proud owner of 7.23883 Bitcoins, which I’d purchased for about $138 each. If I sold my coins now, my original $1,000 investment would be worth $1,700—not a bad return in less than a week’s time. more> http://tinyurl.com/d8t7gex
