Why We Embraced Open Source For Our Database Needs After A Decade Working With Proprietary Solutions

Filed under

After investigating our open source options and due diligence, we picked MariaDB as Teleplan’s new replacement e-TRAC database partner. With MariaDB, we realized significant performance improvements.

For example, whereas running one particular daily report would take up to 15 seconds to run on Oracle Enterprise, with MariaDB it was running in under a second. We did not have the in-house expertise to work on improving the Oracle performance and found this aspect much easier with MariaDB. We also received excellent support both in terms of value and responsiveness and that, coupled with a highly competitive cost, makes MariaDB a great overall package for our e-TRAC needs.

How Capital One is embracing open source

Filed under

I eventually found out that my friends was fed up, the company wouldn't allow him to contribute to open source. Wow. Even in Silicon Valley.

It made me think about how lucky we are at Capital One when it comes to open source. When you think of a financial institution or a bank, transparency and open source software might not be the first thing that you think of, especially with recent scandals. And for many years, the financial sector has used mostly closed source, proprietary software. This was the case for a variety of reasons, including lack of trust in open source software, the need for SLA support, regulations, and to protect intellectual property.

A Portable, Accurate, Low-Cost, Open Source Air Particle Counter

Filed under

If you live in a city with poor air quality you may be aware that particulates are one of the chief contributors to the problem. Tiny particles of soot from combustion, less than 10μm across, hence commonly referred to as PM10. These are hazardous because they can accumulate deep in the lungs, wherein all kinds of nasties can be caused.

There are commercial sensors available to detect and quantify these particles, but they are neither inexpensive nor open source. [Rundong] tells us about a project that aims to change that situation, the MyPart, which is described as a portable, accurate, low-cost, open source air particle counter. There is a GitHub repository for the project as well as a series of Instructables covering the build in detail. It comes from a team of members of the Hybrid Ecologies Lab at UC Berkeley, USA.

Adapting to this new demand, testing teams have to evaluate and verify mobile apps before they are launched in the market. Assessing the quality of mobile devices is a time-consuming and a resource-intensive game especially as automating tests for mobile devices can be moderately complex.

  • Life as an Open Source Developer

    It's been a little over a month since I started my new gig at Stormpath. I gotta say, life is great as an open-source developer! Yes, I did start working for them as a consultant in April, so it's not a huge change for me. However, I only recently realized I haven't written a single line of proprietary code the entire time. My GitHub contributions look pretty good this year. They're nothing like @mojavelinux's or @dsyer's, but I'll get there. Wink

  • Big Data: Why you must consider open source

    A quiet revolution has been taking place in the technology world in recent years. The popularity of Open Source software has soared as more and more businesses have realized the value of moving away from walled-in, proprietary technologies of old.

    And it’s no coincidence that this transformation has taken place in parallel with the explosion of interest in Big Data and analytics. The modular, fluid and constantly-evolving nature of Open Source is in synch with the needs of cutting edge analytics projects for faster, more flexible and, vitally, more secure systems and platforms with which to implement them.

  • Why Open Source Is The Future of Software-Defined-Infrastructure

    Gone are those days when proprietary hardware boxes ruled the roost within data centers. We are propelling towards a very differently-architectured data center where software plays the key role. The era of 'Software-Defined-Everything' is upon us!

    It thus comes as no surprise that enterprises are opting for Open Standards and technologies as their preferred choice for software platforms and operating systems. A recent research paper from IDC states that 85 percent of the surveyed enterprises globally consider Open Source to be the realistic or preferred solution for migrating to Software-Defined-Infrastructure. IDC also recommends to avoid vendor lock-in by deploying Open Source solutions.

  • 9 rules for the proper care and feeding of communities and carnivorous plants

    In 2016, I adopted my first carnivorous plants, a Venus Fly Trap and a Pitcher Plant, which my Facebook friends named Gordon and Bananarama, respectively. I quickly discovered that the health of Gordon and Bananarama was closely connected to the environment I provided as much as to their ability to catch the occasional bug and get energy from the sun. In this article, I'll pull from my experience working with open source communities—and a few months of experience keeping Gordon and Bananarama alive—to explain how caring for carnivorous plants is much like caring for a community.

  • Multiple content processes in Firefox Nightly

    Mozilla revealed yesterday that it plans to enable multiple content processes in Firefox Nightly, the cutting edge development version of the web browser.

    Firefox's multi-process architecture is not yet enabled for all users of the stable version of the browser, currently on version 49.x, but plans are already underway to improve multi-process Firefox.

  • Firefox & Electrolysis - Oxygen for all?

    In these early days of testing and tweaking and gradual and yet incomplete deployment, Firefox with Electrolysis behaves fairly well. On a test box, which is not something that you should ever consider for your production. But overall, apart from the somewhat convoluted setup, it delivered desirable, predictable results.

    However, there was no revolution. Memory and processor utilization were roughly the same as before, and so was the performance, neatly accompanied by a blessedly stable and crash-free experience during my test session. The benefits of the security isolation and going multi will only become apparent in the future, once additional improvements and optimization are added, and once people really start using the feature in earnest. But it is definitely the right step in the right direction. Firefox definitely needs a bit of fresh vitamins, and this just might be what users crave. Anyhow, this be the first test, but it sure ain't the last. See you around, and please heed my findings with a big pinch of salt.

  • Growing Our Build Farm

    We have received our new server for continuous builds of the GNU Guix system, and are putting the finishing touches on its installation. The machine is intended as an eventual replacement for, a virtual machine kindly hosted by the FSF. The new machine will drive our build farm, which continuously compiles the GNU system, and it will feed the mirror with binary packages, so that end users who do not wish to compile packages by themselves can easily keep up-to-date. Time to report on the adventure! This first part covers the hardware.

    Buying the new machine has been made possible through a very generous donation by Igalia to Guix Europe. Igalia is a free software consultancy well known for its involvement in the development of the GNOME stack, GStreamer, the JavaScript compilers of Web browsers, and more, promoting values close to the GNU Guix project. It is heartening that the company is helping us towards our goal of creating a free system that liberates its users to take their computing and data processing needs into their own hands!

  • Enter a Melting Rainbow Universe Fueled by Open-Source Art Tools

    Neon colors explode and transmute abstract patterns in the expressive psychedelic prints of digital artist Zouassi. The massive archive of work by this mysterious glitch artist ranges from the abstract and decorative to the expressive and naturalistic. However, it's hard to categorize his work as a whole because no two canvases look the same. Each colorscape is contained within a distinct pattern or mixture pool that explores different modes of texture and composition.

After a decade, open source Java is still controversial

Filed under

Ten years later, the open-sourcing of Java remains a point of contention, with many in the community extolling the importance of an open Java, while others remain critical of its handling, including the belief that Sun Microsystems didn’t go far enough.

Sun Microsystems officially open-sourced Java on Nov. 13, 2006—a move long pined for by the industry at large. Java’s code had already been accessible prior to that date—a strategy that helped boost the platform from its earliest days, notes Java founder James Gosling.

US Government Opens Access to Federal Source Code with

Filed under

So far, the government is emphasizing the release of at least 20 percent of its custom code as open source. That may not be enough from the perspective of an open source community, but Pittenger argues that “20 percent is a good start. We need to balance the benefits from open sourcing code with the risks associated with vulnerabilities. Keep in mind that outsourced code may have been written by the lowest-cost bidder. For example, we don’t know if any secure development practices were followed, such as threat modeling, security design reviews, or static analysis. We also don’t know whether the contractors building the software closely tracked the open source they used in the code for known vulnerabilities. My advice would be to risk-rank the applications covered by these policies, and start by open sourcing the least critical. I would argue strongly against releasing code that manages sensitive taxpayer information or code for defense and intelligence agencies.”
