An anonymous reader writes "Today version 2.0.0 of Ruby has been released. This is a stable release, and the Ruby team has done their best to make it compatible with 1.9, making it easier to migrate than it was to switch from 1.8 to 1.9. New core language features include: 'Keyword arguments, which give flexibility to API design; Module#prepend, which is a new way to extend a class; A literal %i, which creates an array of symbols easily; __dir__, which returns the dirname of the file currently being executed; and UTF-8 default encoding, which make many magic comments omissible.' There are also new built-in libraries for lazy stream and for an asynchronous exception handling API. The release includes a number of performance improvements and debug support for DTrace."

Questioning his belief in relational database dogma, new submitter Travis Brown happened to evaluate Amazon's Dynamo DB and MonogDB. His situation was the opposite of Jeff Cogswell's: he started off wanting to prefer Dynamo DB, but came to the conclusion that the benefits of Amazon managing the database for him didn't outweigh the features Mongo offers. From the article: "DynamoDB technically isn't a database, it's a database service. Amazon is responsible for the availability, durability, performance, configuration, optimization and all other manner of minutia that I didn't want occupying my mind. I've never been a big fan of managing the day-to-day operations of a database, so I liked the idea of taking that task off my plate. ... DynamoDB only allows you to query against the primary key, or the primary key and range. There are ways to periodically index your data using a separate service like CloudSearch, but we are quickly losing the initial simplicity of it being a database service. ... However, it turns out MongoDB isn't quite as difficult as the nerds had me believe, at least not at our scale. MongoDB works as advertised and auto-shards and provides a very simple way to get up and running with replica sets." His weblog entry has a few code snippets illustrating how he came to his conclusions.
An anonymous reader writes "For a while now, John Carmack has been pushing to bring virtual reality technology back to the gaming world. VR was largely abandoned over a decade ago when it became apparent that the hardware just wasn't ready to support it. In 2013, things are different; cheap displays with a high pixel density and powerful processors designed for small systems are making virtual reality a... reality. One of the last obstacles to be conquered is latency — the delay between moving your head and seeing your perspective change in the virtual world. In a lengthy and highly-technical post at #AltDevBlogADay, Carmack has outlined a number of strategies for mitigating and reducing latency. With information and experience like this being shared with the game development community at large, it shouldn't be long until VR makes a permanent place for itself in our gaming lives."
sl4shd0rk writes "In 2012, Oracle took Google to court over the use of Java in Android. Judge William Alsup brought the ruling that the structure of APIs could not be copyrighted at all. Emerging from the proceedings, it was learned that Alsup himself had some programming background and wasn't bedazzled by Oracle's thin arguments on the range-checking function. The ruling came, programmers rejoiced and Oracle vowed Appeal. It seems that time is coming now, nearly a year later, as Microsoft, BSA, EMC, Netapp, et al. get behind Oracle to overturn Alsup's ruling citing 'destabilization' of the 'entire software industry.'"
Nerval's Lobster writes "Software developer Jeff Cogswell, who matched up Java and C# and peeked under the hood of Facebook's Graph Search, is back with a new tale: why his team decided to go with Amazon's DynamoDB over MongoDB when it came to building a highly customized content system, even though his team specialized in MongoDB. While DynamoDB did offer certain advantages, it also came with some significant headaches, including issues with embedded data structures and Amazon's sometimes-confusing billing structure. He offers a walkthrough of his team's tips and tricks, with some helpful advice on avoiding pitfalls for anyone interested in considering DynamoDB. 'Although I'm not thrilled about the additional work we had to do (at times it felt like going back two decades in technology by writing indexes ourselves),' he writes, 'we did end up with some nice reusable code to help us with the serialization and indexes and such, which will make future projects easier.'"
Two years ago Guile Scheme, the official extension language of the GNU project, released version 2.0, a major upgrade to the implementation. As part of the two year anniversary, the maintainers organized a challenge to hack a small project using Guile in 30 days as part of a birthday software potluck. The two coolest dishes appear to be OpenGL support using the FFI, and XCB bindings built using the XML specification for XCB: "guile-xcb is a language implemented in the Guile VM that parses the XML files used by the xcb project to specify the X protocol and compiles them into Guile modules containing all the methods and data needed to send requests to the X server and receive replies/events back. If new X extensions are added to the xcb library, guile-xcb can compile and add them with no additional work. " See the release announcement for details on the other dishes.
WebMink writes "Is it possible that the CEO of the company that's trying to file a trademark on 'Python' was unaware of Python's importance as a programming technology? That's what he claims — despite running a hosting company that's trying to break into cloud computing, where Python is used extensively. Still, he also regards the Python Software Foundation as a hostile American company and thinks that getting attention from half the world's geeks is a DDoS. From the article: '[The CEO, Tim Poultney,] confirmed that he'd not involved any technical staff in the decisions he'd made about the Python product brand, and told me he regretted that as it would probably have helped him understand the likely reaction to his trademark challenge. ... He said he now understood how offended the global developer community are and told me there was obviously only one outcome that was now possible.'"

snydeq writes "Apple was recently attacked by hackers who infected the Macintosh computers of some employees, the company said on Tuesday in an unprecedented disclosure that described the widest known cyber attacks against Apple-made computers to date, Reuters reports. 'The same software, which infected Macs by exploiting a flaw in a version of Oracle Corp's Java software used as a plug-in on Web browsers, was used to launch attacks against Facebook, which the social network disclosed on Friday. ... A person briefed on the investigation into the attacks said that hundreds of companies, including defense contractors, had been infected with the same malicious software, or malware. The attacks mark the highest-profile cyber attacks to date on businesses running Mac computers.'"
alancronin writes "Similar to Fabien Sanglard's previous code reviews of other games such as the Quake and Doom line of games comes a review of the code base of Duke Nukem 3D (split out over 4 pages). This will be a very good read for anyone interested in understanding the mechanics of a highly addictive game or anyone that wants to learn more about game design."
DavidGilbert99 writes "Facebook admitted last weekend that it was hacked but assured everyone that no data was compromised. However following some investigation by security firm F-Secure, it seems this could be just the tip of the iceberg and that thousands of mobile app developers without the dedicated security team Facebook has in place could already be compromised. The vector for the attack was a mobile developer's website, and the malware used likely targeted Apple's Mac OS X rather than Windows."
imac.usr writes "The Huffington Post is reporting that The Washington Post has gone through yet another round of layoffs, but this time instead of cutting editorial positions, they're apparently cutting IT positions, specifically in the mobile applications department. According to Washington, DC media blog FishbowlDC, 54 people, including the General Manager of Mobile and Director of Mobile Products, were given the axe on Valentine's Day. A particularly damning quote from the FishbowlDC article: '"[CIO and VP Shaliesh] Prakash thinks these are 'inefficiencies' – that is the exact word he uses for human beings who are not useful according to him," said a source who spoke only on condition of anonymity. "Get rid of experienced people to save money, under the garb of streamlining is the new trend inside the Post."' Given that mobile products seem somewhat more likely to succeed than printed newspapers, this seems a strange decision at best."
