School's back in session, and kids love the creative arts. One of my favorite open source creative tools is Audacity, the open source audio recorder and editor. Students love manipulating digital sound with Audacity: making podcasts, learning languages, recording interviews, and recording and mixing music.
I use it to record podcasts for students to provide instructions about classroom procedures and tests. Foreign language students use Audacity to record and play back their lessons. Students can download music and other types of audio tracks for sharing and re-use from Creative Commons and Wikimedia, and dub their own voices onto music tracks, the sounds of birds chirping, whales and dolphins in their natural habitats, and more.
KDE's Kirigami UI Framework for Mobile and Convergent Apps Hits 1.1 Milestone
On September 26, 2016, the KDE developers proudly announced the availability of the first point release for their recently introduced Kirigami UI framework to create mobile and convergent applications.
How Red Hat is making money on the public cloud with a hybrid approach
Red Hat hasn't traditionally played much of a part in public clouds, a fact its CEO Jim Whitehurst underscored in Red Hat's recent earnings call. Though the company is now dabbling in a true elastic/consumption-based delivery and pricing model via OpenShift, Red Hat remains a primarily on-premises business that only feints toward a true cloud model in terms of service delivery.
Ironically, the hybrid cloud may be the trend that gets Red Hat fully planted in the public cloud.
GE, Bosch and open source could bring more IoT tools
The two companies, both big players in industrial IoT, said they will establish a core IoT software stack based on open-source software. They plan to integrate parts of GE's Predix operating system with the Bosch IoT Suite in ways that will make complementary software services from each available on the other.
The work will take place in several existing open-source projects under the Eclipse Foundation. These projects are creating code for things like messaging, user authentication, access control and device descriptions. Through the Eclipse projects, other vendors also will be able to create software services that are compatible with Predix and Bosch IoT Suite, said Greg Petroff, executive director of platform evangelism at GE Software.
Tools are specific concrete things that a culture has decided is a way to improve a process. Buckminster Fuller has a great quote about tools and thinking: "If you want to teach people a new way of thinking, don't bother trying to teach them. Instead, give them a tool, the use of which will lead to new ways of thinking." In particular, DevOps tools can provide folks new ways to look at things—like delivering code into a production environment, for example. But there's lots of examples where a new tool doesn't influence the thinking of the people who use it, so things don't change.
Google says its algorithm can correctly caption a photograph with nearly 94 percent accuracy.
The company says the improvements come in the third version of its system named Inception, with the score coming from a standardized auto-caption test named ImageNet. It reports the first version scored 89.6 percent, the second 91.8 percent and the new one 93.9 percent.
XDA has long been a proponent of open source development, and we’ve seen it flourish over the years. In fact, it’s one of the main reasons our community has grown as fast as it has over these past 13 years, with Android’s core being the driving force. Many people desire to be part of open source and contribute but often don’t know how they can, whether because they think they lack the skills or they just don’t have the time.
Among the changes which arrived in the September release of Firefox 49 were an enhanced set of Reader Mode features, including spoken narration and line-width spacing options. All very welcome. But the improvements aren’t stopping there. Firefox 50, which is due next month, will add another sorely needed feature: a keyboard shortcut for Reader Mode. Y
Why you still need a (permissive) license
Norms aren’t enough if the underlying legal system might allow an early contributor to later wield the law as a threat. That’s why the best practice in the data space is to use something like the Creative Commons public domain grant (CC-Zero) to set a clear, reliable, permissive baseline, and then use norms to add flexible requirements on top of that. This uses law to provide reliability and predictability, and then uses norms to address concerns about fairness, free-riding, and effectiveness. CC-Zero still isn’t perfect; most notably it has to try to be both a grant and a license to deal with different international rules around grants.
With the addition of four new reference materials (RMs) to a growing collection of “measuring sticks” for gene sequencing, the National Institute of Standards and Technology (NIST) can now provide laboratories with even more capability to accurately “map” DNA for genetic testing, medical diagnoses and future customized drug therapies. The new tools feature sequenced genes from individuals in two genetically diverse groups, Asians and Ashkenazic Jews; a father-mother-child trio set from Ashkenazic Jews; and four microbes commonly used in research.
NIST issued the world’s first genome reference material (NIST RM 8398)—detailing the genetic makeup for a woman with European ancestry—in May 2015. Together, all five RMs serve as a collection of well-characterized, whole genome standards that can tell a laboratory how well its DNA sequencing processes are working by measuring the performance of the equipment, chemistry and data analysis involved.
Using the LLVM JIT with PostgreSQL can vastly speed up the query execution performance and shows off much potential but it hasn't been mainlined yet.
Dmitry Melnik presented at this month's LLVM Cauldron over speeding up the query execution performance of PostgreSQL by using LLVM. Particularly with complex queries, the CPU becomes the bottleneck for PostgreSQL rather than the disk. LLVM JIT is used for just-in-time compilation of queries.
The inaugural LLVM Cauldron conference happened earlier this month ahead of the GNU Tools Cauldron in Hebden Bridge, UK. All of the slides and videos from this latest LLVM conference are now available.
