sfcrazy writes "ZFS on Linux has reached what Brian Behlendorf calls an important milestone with the official 0.6.1 release. Version 0.6.1 not only brings the usual bug fixes but also introduces a new property called 'snapdev.' Brian explains, 'The snapdev property was introduced to control the visibility of zvol snapshot devices and may be set to either visible or hidden. When set to hidden, which is the default, zvol snapshot devices will not be created under /dev/. To gain access to these devices the property must be set to visible. This behavior is analogous to the existing snapdir property.'"

The foundation is currently funding a few other projects, including UEFI booting support.
angry tapir writes "When Oracle purchased Sun, many in the open source community were bleak about the future of MySQL. According to MySQL co-creator Michael "Monty" Widenius, these fears have been proven by Oracle's attitude to MySQL and its community. In the wake of the Sun takeover, Monty forked MySQL to create MariaDB, which has picked up momentum (being included by default in Fedora, Open SUSE and, most recently, Slackware). I recently interviewed Monty about what he learned from the MySQL experience and the current state of MariaDB."

First time accepted submitter bobthesungeek76036 writes "On March 26th, Larry Ellison and always with fashionable haircut John Fowler announced the new line of SPARC servers from Oracle. Touted as the fastest microprocessor in the world, they put up some impressive SPEC numbers against much more expensive (and older) IBM hardware. Is the industry still interested in SPARC or is it too late for Larry to regain the server market that Sun Microsystems had many moons ago?" El Reg has a pretty good overview of the new hardware; the T5 certainly looks interesting for highly threaded work loads (there's some massive SMT going on with 16 threads per core), but with Intel dominating for single-threaded performance and ARM-based servers becoming available squeezing them for massive multi-threading, is there really any hope in Oracle's efforts to stay in the hardware game?
An anonymous reader writes "A Google engineer visiting Vietnam discovered a large portion of Vietnamese high school students might be able to pass a Google interview. According to TFA (and his blog), students start learning computing as early as grade 2. According to the blogger and another senior engineer, about half of the students in an 11th grade class he visited would be able to make through their interview process. The blogger also mentioned U.S. school boards blocking computer science education. The link he posted backing up his claim goes to a Maryland Public Schools website describing No Child Left Behind technicalities. According to the link, computer science is not considered a core subject. While the blogger provided no substantial evidence of U.S. school boards blocking computer science education, he claimed that students at Galileo Academy had difficulty with the HTML image tag. According to the school's Wikipedia page, by California standards, Galileo seems to be one of the state's better secondary schools."

First time accepted submitter Gerardo Zamudio writes with the news that Ur-distribution Slackware is replacing MySQL with MariaDB. From an update posted to the Slackware news feed yesterday: "This shouldn't really be a surprise on any level. The poll on LQ showed a large majority of our users were in favor of the change. It's my belief that the MariaDB Foundation will do a better job with the code, be more responsive to security concerns, and be more willing to work with the open source community. And while I don't think there is currently any issue with MySQL's licensing of the community edition for commercial uses, several threads on LQ showed that there is confusion about this, whereas with MariaDB the freedom to use the software is quite clear." (Here's a link to the mentioned poll.)

Surprisingly, there seems to be a viable audience for new releases — one developer says his games sell better on Dreamcast than they do on Nintendo Wii. Even if the buyers vanished, the retro games would still keep coming though: 'I wager I'd have to be dead, or suffering from a severe case of amnesia, to ever give this up completely,' says one developer."

There have been video editing apps available for Linux for years, from ones meant to be friendly enough to compete on the UI front with iMovie (like the moribund Kino, last released in 2009, and the actively developed PiTiVi and Kdenlive) to editors that can apparently do nearly anything, provided the user is a thick-skinned genius — I'm thinking of Broadcast 2000/Cinelerra. Then there's VJ-tool-cum-non-linear editor LiVES, which balances a dense interface with real-time effects for using video as a performance tool, and can run on various flavors of UNIX, including Mac OS X. Dallas-based developer Jonathan Thomas has been working for the last few years on a Free (GPL3 or later), open-source editor called OpenShot, which aims for a happy medium of both usability and power. OpenShot is Linux-only, though, and Thomas is now trying to kickstart (as in, using a Kickstarter project) a cross-platform release for OS X and Windows, too. I've been tempted by dozens of KickStarter projects before, but this is the first one that I've actually pledged to support, and for what may sound like a backwards reason: I like the interface, and am impressed by the feature set, but OpenShot crashes on me a lot. (To be fair, this is mostly to blame on my hardware, none of which is really high-end enough by video-editing standards, or even middle-of-the-road. One day!) So while I like the idea of having a cross-platform, open-source video editor, I have no plans to migrate to Windows; I'm mostly interested in the promised features and stability improvements.

theodp writes "'Someday, and that day may never come,' Don Corleone says famously in The Godfather, 'I'll call upon you to do a service for me.' Back in 2010, filmmaker Lesley Chilcott produced Waiting for 'Superman', a controversial documentary that analyzed the failures of the American public education system, and presented charter schools as a glimmer of hope, including the Bill & Melinda Gates Foundation-backed KIPP Los Angeles Prep. Gates himself was a 'Superman' cast member, lamenting how U.S. public schools are producing 'American Idiots' of no use to high tech firms like Microsoft, forcing them to 'go half-way around the world to recruit the engineers and programmers they needed.' So some found it strange that when Chilcott teamed up with Gates again three years later to make Code.org's documentary short What Most Schools Don't Teach, kids from KIPP Empower Academy were called upon to demonstrate that U.S. schoolchildren are still clueless about what computer programmers do. In a nice coincidence, the film went viral just as leaders of Google, Microsoft, and Facebook pressed President Obama and Congress on immigration reform, citing a dearth of U.S. programming talent. And speaking of coincidences, the lone teacher in the Code.org film (James, Teacher@Mount View Elementary), whose classroom was tapped by Code.org as a model for the nation's schools, is Seattle teacher Jamie Ewing, who took top honors in Microsoft's Partners in Learning (PiL) U.S. Forum last summer, earning him a spot on PiL's 'Team USA' and the chance to showcase his project at the Microsoft PiL Global Forum in Prague in November (82-page Conference Guide). Ironically, had Ewing stuck to teaching the kids Scratch programming, as he's shown doing in the Code.org documentary, Microsoft wouldn't have seen fit to send him to its blowout at 'absolutely amazingly beautiful' Prague Castle. Innovative teaching, at least according to Microsoft's rules, 'must include the use of one or more Microsoft technologies.' Fortunately, Ewing's project — described in his MSDN guest blog post — called for using PowerPoint and Skype. For the curious, here's Microsoft PiL's vision of what a classroom should be."
An anonymous reader writes "Security guru Bruce Schneier contends that money spent on user awareness training could be better spent and that the real failings lie in security design.

We should be designing systems that won't let users choose lousy passwords and don't care what links a user clicks on,' Schneier writes in a blog post on Dark Reading. He says organizations should invest in security training for developers. He goes on, '... computer security is an abstract benefit that gets in the way of enjoying the Internet. Good practices might protect me from a theoretical attack at some time in the future, but they’re a bother right now, and I have more fun things to think about. This is the same trick Facebook uses to get people to give away their privacy. No one reads through new privacy policies; it's much easier to just click "OK" and start chatting with your friends. In short: Security is never salient.'"
An anonymous reader writes "I am a contract developer from a major U.S. city. My rate has never been the lowest, but it's nonetheless very competitive considering the speed and quality of the work I have always delivered, as well as the positive feedback I've received from most clients. In the past ~3 years, I have been working on a sizable project for a major client. For the most part it has been a happy arrangement for both parties. However, for various reasons (including the still ailing economy), starting this year they hired a fresh college graduate in-house, and asked me to teach him all 'secrets' of my code, even though they have the source code by contract. The implicit (although never openly stated) goal is of course for him to take over the project and hopefully reduce cost, at least in the short-term. I say 'hopefully' because I am pretty sure that, because they are unfamiliar with the software industry, they underestimated what it takes to make quality, production-ready code. I am not afraid of losing this particular client, as I have many others, but I want to ask Slashdot: how do you handle this type of situation — training someone whom you know will eventually replace you at your job?"

Nerval's Lobster writes "The one and only Jeff Cogswell is back with an article exploring an issue important to anyone who works with C++. It's been two years since the ISO C++ committee approved the final draft of the newest C++ standard; now that time has passed, he writes, 'we can go back and look at some issues that have affected the language (indeed, ever since the first international standard in 1998) and compare its final result and product to a popular C++ library called Boost.' A lot of development groups have adopted the use of Boost, and still others are considering whether to embrace it: that makes a discussion (and comparison) of its features worthwhile. 'The Standards Committee took some eight years to fight over what should be in the standard, and the compiler vendors had to wait for all that to get ironed out before they could publish an implementation of the Standard Library,' he writes. 'But meanwhile the actual C++ community was moving forward on its own, building better things such as Boost.'"

At the moment, my available options emphasize individual projects of public interest, so we would have to spawn multiple independent projects, seeming to spam the host with 'pointless' minor tasks.

Still more have questioned what it all means for users' privacy—always a touchy subject in conjunction with Facebook. The social network previously revealed how it's adjusting its hardware infrastructure to deal with the spike in traffic that will come from interactions with Graph Search (short answer: the Disaggregated Rack, which will break up hardware resources and scale them independently of one another). Now, in a new blog posting, it's offering a bit more with regard to the software side of things, and how the company repurposed an existing system to solve Graph Search's enormous engineering challenge. Bottom line: Facebook's engineers and executives finally decided on Unicorn, an inverted-index system they'd had in development for quite some time."

An anonymous reader writes "The Parallel Universe blog has a post about parallel data processing. They start off by talking about how Moore's Law still holds, but the shift from clock frequency to multiple cores has stifled the rate at which hardware allows software to scale. (Basically, Amdahl's Law.) The simplest approach to dealing with this is sharding, but that introduces its own difficulties. The more you shard a data set, the more work you need to do to separate out the data elements that can't interact. Optimizing for 2n cores takes more than twice the work of optimizing for n cores. The article says, 'If we want to continue writing compellingly complex applications at an ever-increasing scale we must come to terms with the new Moore's law and build our software on top of solid infrastructure designed specifically for this new reality; sharding just won't cut it.' Their solution is to transfer some of the processing work to the database. 'This because the database is in a unique position to know which transactions may contend for the same data items, and how to schedule them with respect to one another for the best possible performance. The database can and should be smart.' They demonstrate how SpaceBase does this by simulating a 10,000-spaceship battle on different sets of hardware (code available here). Going from a dual-core system to a quad-core system at the same clock speed actually doubles performance without sharding."
