Submission + - 'Bombe' Code-Breaking WW2 Computer Was Used To Decipher Message (bbc.com)

Submitted by Anonymous Coward
An anonymous reader writes: Computer historians have staged a re-enactment of World War Two code-cracking at Bletchley Park. A replica code-breaking computer called a Bombe was used to decipher a message scrambled by an Enigma machine. Held at the National Museum of Computing (TNMOC), the event honored Polish help with wartime code-cracking. Enigma machines were used extensively by the German army and navy during World War Two. This prompted a massive effort by the Allies to crack the complex method they employed to scramble messages. That effort was co-ordinated via Bletchley Park and resulted in the creation of the Bombe, said Paul Kellar who helps to keep a replica machine running at the museum. Renowned mathematician Alan Turing was instrumental in the creation of the original Bombe.

For its re-enactment, TNMOC recruited a team of 12 and used a replica Bombe that, until recently, had been on display at the Bletchley Park museum next door. The electro-mechanical Bombe was designed to discover which settings the German Enigma operators used to scramble their messages. As with World War Two messages, the TNMOC team began with a hint or educated guess about the content of the message, known as a "crib", which was used to set up the Bombe. The machine then cranked through the millions of possible combinations until it came to a "good stop", said Mr Kellar. This indicated that the Bombe had found key portions of the settings used to turn readable German into gobbledygook. After that, said Mr Kellar, it was just a matter of time before the 12-strong team cracked the message.

Submission + - Valve Explains How It Decides Who's a 'Straight Up Troll' Publishing Video Games (vice.com)

Submitted by Anonymous Coward
An anonymous reader writes: Wednesday, Valve, the company that operates the huge online video game store Steam, shared more details about how it plans to control and moderate the ever-increasing number of games published on its platform. In the post published Wednesday, Valve shared more details about how it determines what it considers "outright trolling." "It is vague and we'll tell you why," Valve wrote. "You're a denizen of the internet so you know that trolls come in all forms. On Steam, some are simply trying to rile people up with something we call 'a game shaped object' (ie: a crudely made piece of software that technically and just barely passes our bar as a functioning video game but isn't what 99.9% of folks would say is "good.")

Valve goes on to explain that some trolls are trying to scam folks out of their Steam inventory items (digital items that can be traded for real money), while others are trying to generate a small amount of money through a variety of schemes that have to do with how developers use keys to unlock Steam games, while others are trying to "incite and sow discord." "Trolls are figuring out new ways to be loathsome as we write this," Valve said. "But the thing these folks have in common is that they aren't actually interested in good faith efforts to make and sell games to you or anyone. When a developer's motives aren't that, they're probably a troll." One interesting observation Valve shares in the blog post is that it rarely bans individual games from Steam, and more often bans developers and/or publishers entirely. [...] Valve said that its review process for determining that something may be a "troll game" is a "deep assessment" that involves investigating who the developer is, what they've done in the past, their behavior on Steam as a developer, as a customer, their banking information, developers they associate with, and more.

Submission + - Software Developers Are Now More Valuable To Companies Than Money, Says Survey (cnbc.com)

Submitted by Anonymous Coward
An anonymous reader writes: As our global economy increasingly comes to run on technology-enabled rails and every company becomes a tech company, demand for high-quality software engineers is at an all-time high. A recent study from Stripe and Harris Poll found that 61 percent of C-suite executives believe access to developer talent is a threat to the success of their business. Perhaps more surprisingly — as we mark a decade after the financial crisis — this threat was even ranked above capital constraints. And yet, despite being many corporations' most precious resource, developer talents are all too often squandered. Collectively, companies today lose upward of $300 billion a year paying down "technical debt," as developers pour time into maintaining legacy systems or dealing with the ramifications of bad software. This is especially worrisome, given the outsized impact developers have on companies' chances of success. Software developers don't have a monopoly on good ideas, but their skill set makes them a uniquely deep source of innovation, productivity and new economic connections. When deployed correctly, developers can be economic multipliers — coefficients that dramatically ratchet up the output of the teams and companies of which they're a part.

Submission + - Autonomous Boat Crosses the Atlantic Completing the Microtransat Challenge (apnews.com)

An anonymous reader writes: For the first time an autonomous sailing robot has completed the Microtransat Challenge by crossing the Atlantic from Newfoundland, Canada to Ireland. The Microtransat has been running since 2010 and has seen 23 previous entries all fail to make it across. The successful boat, SB Met was built by the Norwegian company Offshore Sensing AS and is only 2 metres (6.5 ft) long. It completed the crossing on August 26th, 79 days and 5000 km (3100 miles) of sailing after departing Newfoundland on June 7th.
