Ask Slashdot: Choosing a Data Warehouse Server System? 147

Posted by timothy
from the index-cards-and-an-actual-warehouse dept.
New submitter puzzled_decoy writes The company I work has decided to get in on this "big data" thing. We are trying to find a good data warehouse system to host and run analytics on, you guessed it, a bunch of data. Right now we are looking into MSSQL, a company called Domo, and Oracle contacted us. Google BigQuery may be another option. At its core, we need to be able to query huge amounts of data in sometimes rather odd ways. We need a strong ETLlayer, and hopefully we can put some nice visual reporting service on top of wherever the data is stored. So, what is your experience with "big data" servers and services? What would you recommend, and what are the pitfalls you've encountered?

Florida-Based Magic Leap Builds Its Team With Bay Area Hires 161

Tekla Perry writes Stealthy 'cinematic reality' company Magic Leap may be based in Florida--but it's doing a lot of hiring from the Bay Area, scooping up engineers from Pixar, Google, Apple, and Intel--along with a few Willow Garage alums. And it's got openings for many many more. Are all these folks with long-term Silicon Valley roots really going to move to South Florida? Or is Magic Leap getting ready to open up a Silicon Valley research center to house the brain trust it is gathering? Here's what we know about Magic Leap and its technology, who's joining it, and what other kinds of engineers the company aims to hire. Magic Leap has a lot of money to do all that hiring, having just raised more than half a billion dollars, the bulk of it from Google. If you're working in the Bay Area now, would you look forward to a move to Florida, or rather stay where you are?

Android 5.0 Makes SD Cards Great Again 214

from the now-if-you-could-just-add-some-SD-slots-to-nexus-devices dept.
An anonymous reader writes: Over the past couple of years, Google has implemented some changes to how Android handles SD cards that aren't very beneficial to users or developers. After listening to many rounds of complaints, this seems to have changed in Android 5.0 Lollipop. Google's Jeff Sharkey wrote, "[I]n Lollipop we added the new ACTION_OPEN_DOCUMENT_TREE intent. Apps can launch this intent to pick and return a directory from any supported DocumentProvider, including any of the shared storage supported by the device. Apps can then create, update, and delete files and directories anywhere under the picked tree without any additional user interaction. Just like the other document intents, apps can persist this access across reboots." Android Police adds, "All put together, this should be enough to alleviate most of the stress related to SD cards after the release of KitKat. Power users will no longer have to deal with crippled file managers, media apps will have convenient access to everything they should regardless of storage location, and developers won't have to rely on messy hacks to work around the restrictions."

The Effect of Programming Language On Software Quality 217

Posted by Soulskill
from the hold-on-to-your-hats dept. writes: Discussions whether a given programming language is "the right tool for the job" inevitably lead to debate. While some of these debates may appear to be tinged with an almost religious fervor, most people would agree that a programming language can impact not only the coding process, but also the properties of the resulting product. Now computer scientists at the University of California — Davis have published a study of the effect of programming languages on software quality (PDF) using a very large data set from GitHub. They analyzed 729 projects with 80 million SLOC by 29,000 authors and 1.5 million commits in 17 languages. The large sample size allowed them to use a mixed-methods approach, combining multiple regression modeling with visualization and text analytics, to study the effect of language features such as static vs. dynamic typing, strong vs. weak typing on software quality. By triangulating findings from different methods, and controlling for confounding effects such as team size, project size, and project history, they report that language design does have a significant, but modest effect on software quality.

Quoting: "Most notably, it does appear that strong typing is modestly better than weak typing, and among functional languages, static typing is also somewhat better than dynamic typing. We also find that functional languages are somewhat better than procedural languages. It is worth noting that these modest effects arising from language design are overwhelmingly dominated by the process factors such as project size, team size, and commit size. However, we hasten to caution the reader that even these modest effects might quite possibly be due to other, intangible process factors, e.g., the preference of certain personality types for functional, static and strongly typed languages."

Tech Recruiters Defend 'Blacklists,' Lack of Feedback, Screening Techniques 253

Posted by timothy
from the established-procedures dept.
Nerval's Lobster (2598977) writes Remember when executives at Apple, Google, and other firms "fixed" the market for highly skilled tech workers by agreeing not to steal each other's employees? That little incident made a lot of people think about the true modus operandi of corporate and third-party tech recruiters. Dice sat down with some of those recruiters, who talked about everything from "no poaching" tactics to the "blacklist" that exists for candidates who make boneheaded mistakes in interviews. The bottom line? Recruiters seem to pass the blame for some of the industry's most egregious errors on "junior recruiters and agencies," while insisting that their goal in life is to get you a job. How does that align with your experience?

Mozilla Teases First Browser Dedicated To Devs 132

Posted by samzenpus
from the made-just-for-you dept.
hypnosec writes Mozilla has teased a browser for developers — a first of its kind — in a bid to equip developers with a set of tools at one place for better and enhanced productivity. Speaking about the perils of web development Mozilla says engineers, while building for the web, use a range of tools that don't always work well together. Because of this, they have to switch between platforms. This process of switching from one platform to another makes a developer less productive, Mozilla says. The not-for-profit organization hasn't detailed its browser for developers to a great extent, but has revealed that the browser will be available on November 10.

Xcott Craver writes The 7th Underhanded C Contest is now open. The goal of the contest is to write code that is as readable, clear, innocent and straightforward as possible, and yet somehow exhibits evil behavior that cannot be seen even when staring at the source code. The winners from 2013 are also online, and their clever and insightful submissions make for fun reading.

Amazon Releases (Not Many) Details On Its Workforce Demographics 123

Posted by timothy
from the how-many-people-do-you-employ? dept.
theodp (442580) writes Late to the table on disclosing workforce demographics, Amazon posted a diversity report to its website on Halloween, revealing that its global work force is 63% male and 37% female, while in the U.S., its work force is 60% white, 15% black, 13% Asian and 9% Hispanic. More lacking in granular detail than the less-than-transparent diversity data provided by its tech peers, Rainbow PUSH said Amazon's numbers were not as good as they appeared, and criticized the company for a lack of candor. "Their general work force data released by Amazon seems intentionally deceptive, as the company did not include the race or gender breakout of their technical work force," PUSH said in a statement. "The broad assumption is that a high percentage of their black and Latino employees work in their warehouses." Following the lead of other tech companies, Diversity at Amazon suggests the e-tailer's undisclosed-but-presumed lack of tech diversity could be blamed on "female students and students of color [who] are opting out of technology and engineering" as early as middle school and high school. Taking a page from Google's playbook, Amazon pointed to its involvement with the Anita Borg Institute,, Girls Who Code, and the National Center for Women & Information Technology as ways the company's addressing tech diversity deficiencies.

It's Time To Revive Hypercard 299

Posted by timothy
from the overdue-as-open-source dept. writes HyperCard, an application program and programming tool released for the Apple Macintosh in 1987, represented the 'computing for the people' philosophy that enabled users to go past the pre-built software that came on their machines, and to program and build software of their own. "Mac users could use Hypercard to build their own mini-programs to balance their taxes, manage sports statistics, make music – all kinds of individualized software that would be useful (or fun) for individual users." Now Jer Thorp writes that the end of HyperCard left a huge gap that desperately needs to be filled – a space for an easy to use, intuitive tool that will once again let average computer users make their own tools. According to Throp, this type of plain-language programming makes sense, particularly in an application that was designed specifically for non-programmers. "I find the largest concern for learners to be not with the conceptual hurdles involved in writing a program, but with obscure and confusing syntax requirements. I would love to be able to teach HyperTalk to my students, as a smooth on-road to more complex languages like JavaScript, Java or C++." By putting the tools of creation into the hands of the broader userbase, we would allow for the creation of ultra-specific personalized apps that, aside from a few exceptions, don't exist today."

HyperTalk wasn't just easy, it was also fairly powerful. Complex object structures could be built to handle complicated tasks, and the base language could be expanded by a variety of available external commands and functions (XCMDs and XFCNs, respectively), which were precursors to the modern plug-in. But ultimately, HyperCard would disappear from Mac computers by the mid-nineties, eclipsed by web browsers and other applications which it had itself inspired. The last copy of HyperCard was sold by Apple in 2004. "One thing that's changed in the intervening decades is that the hobbyist has largely gone by the wayside. Now you're either a user or a full-fledged developer, and the gulf is wider than ever," writes Peter Cohen. "There's really nothing like it today, and I think the Mac is lesser for it."

Tao3D: a New Open-Source Programming Language For Real-Time 3D Animations 158

Posted by timothy
from the not-quite-minecraft dept.
descubes (35093) writes "Tao3D is a new open-source programming language designed for real-time 3D animations. With it, you can quickly create interactive, data-rich presentations, small applications, proofs of concept, user interface prototypes, and more. The interactivity of the language, combined with its simplicity and graphical aspects, make it ideal to teach programming.

Tao3D also demonstrates a lot of innovation in programming language design. It makes it very easy to create new control structures. Defining if-then-else is literally a couple of lines of code. The syntax to pass pass blocks of code to functions is completely transparent. And it is fully reactive, meaning that it automatically reacts as necessary to external events such as mouse movements or the passage of time.

The source code was just made available under the GNU General Public License v3 on SourceForge [as linked above], GitHub and Gitorious."

Mark Zuckerberg And John Doerr Donate $1M To Expand The Hour Of Code Campaign 24

Posted by samzenpus
from the pay-up dept.
theodp writes Techcrunch reports that Mark Zuckerberg has donated $500K to expand the Hour of Code campaign, which aims to reach 100 million students this year with its learn-to-code tutorials, including its top-featured tutorial starring Zuckerberg (video). Techcrunch adds that Zuckerberg's donation will be matched by fellow tutorial team teacher Bill Gates (video), Microsoft, Reid Hoffman, Salesforce, Google, and others. Zuck and Gates appear to have a sizable captive audience — a District Partnership Model brochure on the code-or-no-HS-diploma-for-you Chicago Public Schools' website calls for partner districts to "hold a district-wide Hour of Code event each year" for three years.

Getting 'Showdown' To 90 FPS In UE4 On Oculus Rift 30

Posted by timothy
from the cutting-all-corners dept.
An anonymous reader writes Oculus has repeatedly tapped Epic Games to whip up demos to show off new iterations of Oculus Rift VR headset hardware. The latest demo, built in UE4, is 'Showdown', an action-packed scene of slow motion explosions, bullets, and debris. The challenge? Oculus asked Epic to make it run at 90 FPS to match the 90 Hz refresh rate of the latest Oculus Rift 'Crescent Bay' prototype. At the Oculus Connect conference, two of the developers from the team that created the demo share the tricks and tools they used to hit that target on a single GPU.

Google Announces Project Ara Developer Conference, Shows Off First Prototype 66

from the save-the-date dept.
An anonymous reader writes Google today announced it will be hosting the second iteration of its Project Ara Module Developers Conference for its modular device project early next year. The first event will be in Mountain View on January 14, 2015, with satellite locations at Google offices in New York City, Buenos Aires, and London. The same agenda will be repeated in Singapore on January 21, 2015, with satellite locations at Google offices in Bangalore, Tokyo, Taipei, and Shanghai. The company also released a video showing off the first prototype from Project Ara. Until now, all we've seen so far are industrial design models. This one actually boots up.

It's Official: HTML5 Is a W3C Standard 125

rjmarvin (3001897) writes The Worldwide Web Consortium today has elevated the HTML5 specification to 'recommendation' status , giving it the group's highest level of endorsement, which is akin to becoming a standard. The W3C also introduced Application Foundations with the announcement of the HTML5 recommendation to aid developers in writing Web applications, and said the organization is working with patents holders of the H.264 codec to agree on a baseline royalty-free interoperability level commitment.

Here's Why Apple Rejected Your iOS App 145

Posted by samzenpus
from the you-can-keep-it dept.
Nerval's Lobster writes Everybody knows that Apple runs a tight ship when it comes to approving iOS apps for its App Store, rejecting software because it features porn, allows gambling, installs types of executable code, etc. But Apple also denies apps for some pretty esoteric reasons, many of which are only just coming to light. Want to have an App that uses GPS to automatically control a real-world aircraft or automobile? Sorry, that's not allowed, presumably because Apple doesn't want iOS to serve as a drone controller. (Imagine the liability issues.) Also, apps that report your location to emergency services are forbidden, as well as any that misspell Apple product names ("iTunz" will never make it through, no matter how much you beg). Even if Apple's not sharing the exact reason why it just rejected your app from its store (what the heck does "Not enough lasting value" mean?), you can check out Apple's own page on the top reasons for iOS app rejections."
