Samsung's Position On Tizen May Hurt Developer Recruitment 76

Posted by Soulskill
from the don't-change-horses dept.
CowboyRobot sends in an article about how Samsung's constantly shifting plans for its smartwatches are making it hard for developers to commit to building apps. Quoting: "Samsung's first smartwatch, released in October last year, ran a modified version of Google's Android platform. The device had access to about 80 apps at launch, all of which were managed by a central smartphone app. Samsung offered developers an SDK for the Galaxy Gear so they could create more apps. Developers obliged. Then Samsung changed direction. Samsung announced a new series of smartwatches in February: the Gear 2, Gear 2 Neo, and Gear Fit. Unlike the first device, these three run Samsung’s Tizen platform. ... This week, Samsung made things even more interesting. Speaking to Reuters, Yoon Han-kil, senior vice president of Samsung’s product strategy team, said the company is working on a watch that will use Google’s Android Wear platform. In other words, Samsung will bring three different watches to market with three different operating systems in under a year."

Linux Voice is a New Magazine for Linux Users — On Paper (Video) 62

Posted by Roblimo
from the there's-nothing-quite-like-the-smell-of-ink-on-paper dept.
This is an interview with Graham Morrison, who is one of four people behind the shiny-new Linux Voice magazine, which is printed on (gasp) paper. Yes, paper, even though it's 2014 and a lot of people believe the idea of publishing a physical newspaper or magazine is dead. But, Graham says, when you have a tight community (like Linux users and developers) you have an opportunity to make a successful magazine for that community. This is a crowdfunded venture, through Indiegogo, where they hoped to raise £90,000 -- but ended up with £127,603, which is approximately $214,288 as of this video's publishing date. So they have a little capital to work with. Also note: these are not publishing neophytes. All four of the main people behind Linux Voice used to work on the well-regarded Linux Format magazine. Graham says they're getting subscribers and newsstand sales at a healthy rate, so they're happily optimistic about their magazine's future. (Here's an alternate video link)

Apache OpenOffice Reaches 100 Million Downloads. Now What? 273

Posted by timothy
from the hundreds-of-millions-served dept.
We're thankfully long past the days when an emailed Word document was useless without a copy of Microsoft Word, and that's in large part thanks to the success of the OpenOffice family of word processors. "Family," because the OpenOffice name has been attached to several branches of a codebase that's gone through some serious evolution over the years, starting from its roots in closed-source StarOffice, acquired and open-sourced by Sun to become OpenOffice.org. The same software has led (via some hamfisted moves by Oracle after its acquisition of Sun) to the also-excellent LibreOffice. OpenOffice.org's direct descendant is Apache OpenOffice, and an anonymous reader writes with this excellent news from that project: "The Apache Software Foundation (ASF), the all-volunteer developers, stewards, and incubators of more than 170 Open Source projects and initiatives, announced today that Apache OpenOffice has been downloaded 100 million times. Over 100 million downloads, over 750 extensions, over 2,800 templates. But what does the community at Apache need to do to get the next 100 million?" If you want to play along, you can get the latest version of OpenOffice from SourceForge (Slashdot's corporate cousin). I wonder how many government offices -- the U.S. Federal government has long been Microsoft's biggest customer -- couldn't get along just fine with an open source word processor, even considering all the proprietary-format documents they're stuck with for now.

Code Quality: Open Source vs. Proprietary 131

Posted by Soulskill
from the put-your-money-where-your-code-is dept.
just_another_sean sends this followup to yesterday's discussion about the quality of open source code compared to proprietary code. Every year, Coverity scans large quantities of code and evaluates it for defects. They've just released their latest report, and the findings were good news for open source. From the article: "The report details the analysis of 750 million lines of open source software code through the Coverity Scan service and commercial usage of the Coverity Development Testing Platform, the largest sample size that the report has studied to date. A few key points: Open source code quality surpasses proprietary code quality in C/C++ projects. Linux continues to be a benchmark for open source quality. C/C++ developers fixed more high-impact defects. Analysis found that developers contributing to open source Java projects are not fixing as many high-impact defects as developers contributing to open source C/C++ projects."

How Does Heartbleed Alter the 'Open Source Is Safer' Discussion? 579

Posted by Soulskill
from the or-at-least-marginally-less-unsafe dept.
jammag writes: "Heartbleed has dealt a blow to the image of free and open source software. In the self-mythology of FOSS, bugs like Heartbleed aren't supposed to happen when the source code is freely available and being worked with daily. As Eric Raymond famously said, 'given enough eyeballs, all bugs are shallow.' Many users of proprietary software, tired of FOSS's continual claims of superior security, welcome the idea that Heartbleed has punctured FOSS's pretensions. But is that what has happened?"

Linux 3.15 Will Suspend & Resume Much Faster 117

Posted by Soulskill
from the cutting-into-my-foot-tapping-time dept.
An anonymous reader writes "The Linux 3.15 kernel now in its early life will be able to suspend and resume much faster than previous versions of the Linux kernel. A few days ago we saw ACPI and Power Management updates that enable asynchronous threads for more suspend and resume callbacks. Carrying out more async operations leads to reduced time for the system suspend and then resuming. According to one developer, it was about an 80% time savings within one of the phases. On Friday, work was merged that ensured the kernel is no longer blocked by waiting for ATA devices to resume. Multiple ATA devices can be woken up simultaneously, and any ATA commands for the device(s) will be queued until they have powered up. According to an 01.org blog post on the ATA/SCSI resume optimization patches, when tested on three Intel Linux systems the resume time was between 7x and 12x faster (not including the latest ACPI/PM S&R optimizations)."

Phil Shapiro says 20,000 Teachers Should Unite to Spread Chromebooks (Video) 101

Posted by Roblimo
from the computers-for-eager-young-minds-and-fingers dept.
Phil Shapiro often loans his Chromebook to patrons of the public library where he works. He says people he loans it to are happily suprised at how fast it is. He wrote an article earlier this month titled Teachers unite to influence computer manufacturing that was a call to action; he says that if 20,000 teachers demand a simple, low-cost Chromebook appliance -- something like a Chrome-powered Mac mini with a small SSD instead of a hard drive, and of course without the high Mac mini price -- some computer manufacturer will bite on the idea. Monitors? There are plenty of used ones available. Ditto speakers and keyboards, not that they cost much new. The bottom line is that Phil believes Chromebooks, both in their current form factor and in a simpler one, could be "the" computer for schools and students. Maybe so, not that Android tablets are expensive or hard to use. And wait! Isn't there already a Chromebox? And even a Chromebase all-in-one Chrome-based desktop? In any case, Chrome-based computers look pretty good for schools and libraries, especially if and when prices for the simplest members of the family get down to where Phil thinks they should be.

Ask Slashdot: How To Start With Linux In the Workplace? 451

Posted by timothy
from the sounds-like-mint-works-for-you dept.
An anonymous reader writes "Recently my boss has asked me about the advantages of Linux as a desktop operating system and if it would be a good idea to install it instead of upgrading to Windows 7 or 8. About ten boxes here are still running Windows XP and would be too old to upgrade to any newer version of Windows. He knows that i am using Linux at work on quite outdated hardware (would have gotten a new PC but never requested new hardware — Linux Mint x64 runs quite well on it) and i always managed to get my stuff done with it. I explained to him that there are no licensing issues with Linux, there is no anti-virus software to deal with and that Linux is generally a bit more efficient on old hardware than operating systems from Microsoft. The boss seems interested." But that's not quite the end; read on for this reader's question.

Princeton Students Develop Open Source Voice Control Platform For Any Device 34

Posted by Unknown Lamer
from the yell-at-your-computer-more-effectively dept.
rjmarvin (3001897) writes "Two Princeton computer science students have created an open source platform for developing voice-controlled applications that are always on. Created by Shubhro Saha and Charlie Marsh, Jasper runs on the Raspberry Pi under Raspbian, using a collection of open source libraries to make up a development platform for building voice-controlled applications. Marsh and Saha demonstrate Jasper's capability to perform Internet searches, update social media, and control music players such as Spotify. You need a few easily obtainable bits of hardware (a USB microphone, wifi dongle or ethernet, and speakers). The whole thing is powered by CMU Sphinx (which /. covered the open sourcing of back in 2000). Jasper provides Python modules (under the MIT license) for recognizing phrases and taking action, or speaking when events occur. There doesn't seem to be anything tying it to the Raspberry Pi either, so you could likely run it on an HTPC for always-on voice control of your media center.

Intel Releases $99 'MinnowBoard Max,' an Open-Source Single-Board Computer 97

Posted by timothy
from the embed-and-deploy dept.
A few months back, we posted a video interview with some of the folks behind the Linux-friendly, x86-based MinnowBoard. TechCrunch reports the release of a more powerful version of the same all-in-one computer, now with a 1.91GHz Atom E3845 processor. According to the linked article, "The board's schematics are also available for download and the Intel graphics chipset has open-source drivers so hackers can have their way with the board. While it doesn’t compete directly with the Raspberry Pi – the Pi is more an educational tool and already has a robust ecosystem – it is a way for DIYers to mess around in x86 architected systems as well as save a bit of cash. The system uses break-out boards called Lures to expand functionality."

Ask Slashdot: User-Friendly Firewall For a Brand-New Linux User? 186

from the perfect-security-on-the-way dept.
An anonymous reader writes "I am a new Linux user; I'm on 2nd day now. Currently I am trying out Ubuntu, but that could change. I am looking for a user friendly firewall that I can set up that lets me do these things:1) set up a default deny rule 2) carve out exceptions for these programs: browser, email client, chat client, yum and/or apt. 3) carve out exceptions to the exceptions in requirement 2 — i.e. I want to be able to then block off IPs and IP ranges known to be used by malware, marketers, etc., and all protocols which aren't needed for requirement 2. It also needs to have good enough documentation that a beginner like me can figure it out. Previously, I had done all of the above in AVG Firewall on Windows, and it was very easy to do. So far, I have tried these things:1) IPTABLES — it looked really easy to screw it up and then not notice that it's screwed up and/or not be able to fix it even if I did notice, so I tried other things at that point... 2) searched the internet and found various free firewalls such as Firestarter, GUFW, etc., which I weren't able to make meet my requirements. Can someone either point me to a firewall that meets my needs or else give me some hints on how to make firestarter or GUFW do what I need?"

An anonymous reader writes "The F# programming language team has been providing source code releases for years, but all contributions to the core implementation were internal. Microsoft is now changing that. They've announced that they'll be accepting code contributions from the community for the core F# language, the compiler, library, and Visual F# tools. They praised the quality of work currently being done by the F# community: 'The F# community is already doing high-quality, cross-platform open engineering using modern tools, testing methodology and build processes. Some particularly active projects include the Visual F# Power Tools, FSharp.Data, F# Editing Support for Open Editors, the Deedle DataFrame library and a host of testing tools, web tools, templates, type providers and other tools.'

Linus Torvalds Suspends Key Linux Developer 641

from the arguing-about-penguins dept.
alphadogg writes: "An argument between developers of some of the most basic parts of Linux turned heated this week, resulting in a prominent Red Hat employee and code contributor being banned from working on the Linux kernel. Kay Sievers, a well-known open-source software engineer, is a key developer of systemd, a system management framework for Linux-based operating systems. Systemd is currently used by several prominent Linux distributions, including two of the most prominent enterprise distros, Red Hat and SUSE. It was recently announced that Ubuntu would adopt systemd in future versions as well. Sievers was banned by kernel maintainer Linus Torvalds on Wednesday for failing to address an issue that caused systemd to interact with the Linux kernel in negative ways."

Canonical Shutting Down Ubuntu One File Services 161

Posted by Unknown Lamer
from the at-least-we-get-code dept.
jones_supa (887896) writes "Wanting to focus their efforts on their most important strategic initiatives and ensuring that the company is not spread too thin, Canonical is shutting down Ubuntu One file services. With other services now regularly offering from 25 GB to 50 GB of free storage, the personal cloud storage space wasn't a sustainable place for Canonical. As of today, it will no longer be possible to purchase storage or music from the Ubuntu One store. The Ubuntu One software will not be included in the upcoming Ubuntu 14.04 LTS release, and the Ubuntu One apps in older versions of Ubuntu and in the Ubuntu, Google, and Apple stores will be updated appropriately.

The current services will be unavailable from 1 June 2014; user content will remain available for download until 31 July, at which time it will be deleted. For a spark of solace, the company promises to open source the backend code."

oVirt 3.4 Means Management, VMs Can Live On the Same Machine 51

darthcamaro (735685) writes "Red Hat's open source oVirt project hit a major milestone this week with the release of version 3.4. It's got improved storage handling so users can mix and match different resource types, though the big new feature is one that seems painfully obvious. For the first time oVirt users can have the oVirt Manager and oVirt VMs on the same physical machine. 'So, typically, customers deployed the oVirt engine on a physical machine or on a virtual machine that wasn't managed or monitored,' Scott Herold, principal product manager for Red Hat Enterprise Virtualization said. 'The oVirt 3.4 release adds the ability for oVirt to self-host its engine, including monitoring and recovery of the virtual machine.'"

Canonical's Troubles With the Free Software Community 155

puddingebola (2036796) writes "Bruce Byfield looks back at the soured relationships between Canonical and the free software community. Partly analysis, partly a review of past conflicts, the writer touches on Mir and Wayland, and what he sees as Canonical's attempts to take over projects. From the article, 'However, despite these other concerns, probably the most important single reason for the reservations about Ubuntu is its frequent attempts to assume the leadership of free software — a position that no one has ever filled, and that no one particularly wants to see filled. In its first few years, Ubuntu's influence was mostly by example. However, by 2008, Shuttleworth was promoting the idea that major projects should coordinate their release schedules. That idea was received without enthusiasm. However, it is worth noting that some of those who opposed it, like Aaron Seigo, have re-emerged as critics of Mir — another indication that personal differences are as important as the issues under discussion.'"

How 3D Printer Maker Aleph Objects Pushes the Open Source Envelope 51

Posted by timothy
from the catch-us-if-you-can dept.
Lemeowski (3017099) writes "In a time where there's a 'gold rush' for 3D printing patents, there's one company that's doing everything it can to keep its 3D printers as open as possible. Jeff Moe, CEO of Aleph Objects, said in an interview with Opensource.com that his company's strategy is 'to not patent anything, but to establish prior art as soon as we can. So when we develop things we try to push it out there as soon as possible and hope to establish prior art if there isn't prior art already. That allows us to develop a lot more quickly.' The company makes the Lulzbot 3D printers, and goes to the extreme of publishing every last detail about its printers, Moe said, including syncing its internal file system that it uses to share files on the development of the machine to the public every hour so you can see what they're doing."
