  • AtScale Delivers Findings on BI-Plus-Hadoop

    Business intelligence is the dominant use-case for IT organizations implementing Hadoop, according to a report from the folks at AtScale. The benchmark study also shows which tools in the Haddop ecosystem are best for particular types of BI queries.

    As we've reported before, tools that demystify and function as useful front-ends and connectors for the open source Hadoop project are much in demand. AtScale, billed as “the first company to allow business users to do business intelligence on Hadoop,” focused its study on the strengths and weaknesses of the industry’s most popular analytical engines for Hadoop – Impala, SparkSQL, Hive and Presto.

  • Study Says OpenStack at Scale Can Produce Surprising Savings

    Revenues from OpenStack-based businesses are poised to grow by 35 percent a year to more than $5 billion by 2020, according to analysts at 451 Research. In its latest Cloud Price Index, 451 Research analyzes the costs associated with using various cloud options to determine when it becomes better value to use a self-managed private cloud instead of public or managed cloud services.

    The idea is to createa complex pricing model that takes into consideration the major factors impacting total cost of ownership (TCO), including salaries and workload requirements.The 451 study found that because of the prevalence of suitably qualified administrators, commercial private cloud offerings such as VMware and Microsoft currently offer a lower TCO when labor efficiency is below 400 virtual machines managed per engineer. But where labor efficiency is greater than this, OpenStack becomes more financially attractive. In fact, past this tipping point, all private cloud options are cheaper than both public cloud and managed private cloud options.

  • How OpenStack mentoring breaks down cultural barriers

    Victoria Martinez de la Cruz is no stranger to OpenStack's mentorship opportunities. It's how she got her own start in OpenStack, and now a few years later is helping to coordinate many of these opportunities herself. She is speaking on a panel on mentoring and internships later this week at OpenStack Summit in Barcelona, Spain. In this interview, we catch up with Victoria to learn more about the details of what it's like to be a part of an open source internship, as well as some helpful advice for people on both sides of the mentoring process.

  • Spark on Kubernetes at Spark Summit EU

    I’ll be speaking about Spark on Kubernetes at Spark Summit EU this week. The main thesis of my talk is that the old way of running Spark in a dedicated cluster that is shared between applications makes sense when analytics is a separate workload. However, analytics is no longer a separate workload — instead, analytics is now an essential part of long-running data-driven applications. This realization motivated my team to switch from a shared Spark cluster to multiple logical clusters that are co-scheduled with the applications that depend on them.

Distributing encryption software may break the law

Security
Legal

Developers, distributors, and users of Free and Open Source Software (FOSS) often face a host of legal issues which they need to keep in mind. Although areas of law such as copyright, trademark, and patents are frequently discussed, these are not the only legal concerns for FOSS. One area that often escapes notice is export controls. It may come as a surprise that sharing software that performs or uses cryptographic functions on a public website could be a violation of U.S. export control law.

Export controls is a term for the various legal rules which together have the effect of placing restrictions, conditions, or even wholesale prohibitions on certain types of export as a means to promote national security interests and foreign policy objectives. Export control has a long history in the United States that goes back to the Revolutionary War with an embargo of trade with Great Britain by the First Continental Congress. The modern United States export control regime includes the Department of State's regulations covering export of munitions, the Treasury Department's enforcement of United States' foreign embargoes and sanctions regimes, and the Department of Commerce's regulations applying to exports of "dual-use" items, i.e. items which have civil applications as well as terrorism, military, or weapons of mass destruction-related applications.

  • An introduction to color spaces

    The Kernel Recipes conference is, unsurprisingly, focused on kernel-related topics, but one of the potentially most useful talks given there was only marginally about the kernel. Applications that deal with the acquisition or display of video data must be aware of color spaces, but few developers really understand what color spaces are or how they work. Media subsystem maintainer Hans Verkuil sought to improve this situation with an overview of the color-space abstraction.

  • A tale of two conferences

    The "small" criterion can be a bit of a problem since it, naturally, limits the number of people who can participate in this kind of event. The Linux Plumbers Conference (now just a few weeks away) is always trying to find the right balance between size and quality of the event, and there, too, tickets tend to sell out quickly. The nice thing about an event like Kernel Recipes, though, is that it ought to be reproducible in other parts of the world. We have a ready supply of good speakers and interesting things to talk about in our community, and it doesn't take that many speakers to make an event like this work.

    In the end, it was a privilege to be able to attend both events. Your editor's only regret was being unable to stay in Berlin for the Embedded Linux Conference Europe the following week. Conferences are an opportunity to get a sense for what is happening in our community and to renew one's enthusiasm and energy; both LinuxCon and Kernel Recipes succeeded on all of those fronts. A diverse community needs a diverse range of events; happily, that is just what was in store in Europe during these weeks.

  • An Open Source, Self-Hosted Heroku

    Running our own Heroku… It shouldn't be that hard, right?

    We have a small set of servers we use to run our internal applications. Nothing too complex, just monitoring, our ELK stack, Jenkins, and a few internal services.

    Given our rather modest requirements it may seem obvious that our first attempt at deployment automation, Chef, was a bit overkill for our needs. Not only that, we also wanted our engineers to be able to easily deploy applications to our servers without having to set up a Chef recipe — like the role Heroku plays in many of our client projects. We could have decided to run our internal applications on Heroku as well, but their pricing model wasn’t compatible with our relatively small-scale requirements.

  • The role of Free Software in a world that doesn't care

    The Free Software movement is about personal and social liberties. Giving the owner and user of a computer control over it. But most people don't see the problem with a small number of multinational mega-corporations having control over everyone's computers. They think: “Apple and Microsoft know what they're doing, and they do a good job, so why would I need Free Software?”

    Accepting that most people reject the Free Software message, what can the Free Software movement contribute to the world?

The basics of open source quality assurance

Filed under
OSS

Open source depends on a sustainable community to develop code rapidly, debug code effectively, and build out new features. Because community involvement is voluntary, people's skills, levels of involvement, and time commitments can vary. Given the variable nature of these factors, along with the fact that open source often relies on a philosophy of "release early, release often," quality assurance can be become challenging.

    After releasing daily snapshots without interruption for 17 days, Tumbleweed did slow down a bit during the last week. As already mentioned in my last review, 1124 had been canceled due to an issue with sddm installing strange branding configurations. And later on, we ‘broke’ our own staging setup and needed to bootstrap a few of them, making the throughput much lower than you were used to. So, we ended up with 3 snapshots since my last review: 1125, 1128 and 1129.
