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.
A quick introduction to Audacity for teachers
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.
My wife, TLW, runs GNU/Linux with few problems. She uses a tablet, an Odroid-C2 ARMed thick client, and a big notebook all running Debian GNU/Linux or Ubuntu and her Android/Linux smartphone and her scanner and printer all deal with Beast, my GNU/Linux server. I have her file-system plugged in via NFS so she can do IT in bed, in front of the TV, on TV, or in her office and all her thousands of pictures, documents, scans etc. are all in the same place.
She doesn’t even have much problem using Ubuntu or XFCE4 on Debian because she mostly uses the same applications all day long. It just works for her and memories of That Other Operating System are fading. She was locked to a single thick client with limited capabilities in those Dark Days. She had repeated crashes and malware. Today, her issues with IT are things like changing the name of a file on the FTP server or how to scan a light image or…, real problems, not problems M$ causes billions of people every day.
When Microsoft came out with its first batch of Surface tablets a few years ago, the company took a bath on them. It didn't help that they were conceived around the unpopular Windows 8 and the now-defunct Windows RT and that the prospects for the OS were in question. After Microsoft wrote off $900 million on its money-losing Surface business, the deathwatch was on. But the Intel-based Surface Pro and Surface Pro 2 showed a glimmer of hope, and Microsoft finally delivered a solid hit with the Surface Pro 3. After that watershed release, the Surface division is now an important business that brings in more than $1 billion revenue per quarter. Yet Microsoft isn't showing much appreciation toward the customers who helped put its Surface business on solid footing.
Skylable is proud to announce immediate availability of SX 2.2. The new release provides a significant performance boost by improving calculation, index usage and maintaining cache of frequently computed values, as well as performing background propagation of all replicas above 1 by default. Additionally, sxfs now enables caching of smaller objects for improved latency. The source code and binary packages are available for download now. SX 2.2 is backward compatible with previous 2.x releases, and all you need to do is to run sxsetup –upgrade on every node after updating it!
The game is listed as Single-player and Multi-player, so it's not entirely clear what type of game it is. As it also claims it's an MMO. I think the developer needs to make it much clearer exactly what is online and what is offline.
At the point you are presented with a job offer, your prospective employer really wants to hire you. Chances are, they’ve screened and interviewed a number of candidates and put a lot of work into the process. Your manager has thought deeply about who they want in the position and has probably imagined how it will all work out with you in the role. Both you and the hiring decision-maker(s) are probably very optimistic about what you’ll accomplish in the role and how well you’ll get along working together. At this point, no one wants to go back to the drawing board and start the process over again. You will be excited to start the new job but it’s worth taking a step back to appreciate the unusual position you are in with your new employer.
Softpedia was informed today, September 26, 2016, by Black Lab Software's CEO Robert J. Dohnert about the availability of the third Beta development snapshot of the upcoming Black Lab Linux 8 GNU/Linux operating system.
Black Lab Linux 8 "Onyx" Beta 3 is here approximately three weeks after the second Beta pre-release and it comes with a major change. It is no longer based on Ubuntu 14.04 LTS (Trusty Tahr), as the development team decided to switch base and move to the next Ubuntu LTS version, namely Ubuntu 16.04 LTS (Xenial Xerus).
Since the last time I touched working code in a production environment, it’s no exaggeration to say that no part of the development process remains untouched. Over the last decade plus, effectively every aspect of the application development process has been scrutinized, rethought and in many cases reinvented. From version control to build systems to configuration and deployment to monitoring, modern development’s toolchain is multi-part and sophisticated.
As it must be. Processes that work for code released in cycles measured in months cannot be expected to handle workflows measured in days or minutes.
For all that the process of developing software has evolved, however, the database remains curiously overlooked. Consider the example of Cloud Native. Describing a modern, typically legacy-free approach to building applications appropriate for cloud environments, the term Cloud Native has gone from informal descriptor to accepted industry shorthand in short order – to the extent that it has its own technical foundation.
If we look at the membership of that foundation, the CNCF, it would appear that the roster includes no database vendors at the Platinum or Gold membership levels, at least if you assume Google’s involvement is around Kubernetes and not tools such as BigQuery. Of the 41 silver members, meanwhile, two can be considered database vendors: Crunchy and Treasure Data.
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.
