  • Tizen Developer Summit 2015 Bengaluru – Inaugural Keynote
  • Linaro Connect US '15

    One of the items that came out of Linux plumbers for me was discussion on the future of the Ion memory manager for Android. While not as relevant to my day to day work anymore, I still have a lot of background knowledge and input to give. Linaro Connect happened a little over a month after plumbers and I was up there for the week, mostly for Ion and other ARM talks. (Non-technically, being at Linaro Connect also meant I could avoid the chaos in my apartment from an impending move. Yay for convenient excuses!)

  • LinuxCon Europe 2015 in Dublin

    The second day was opened by Leigh Honeywell and she was talking about how to secure an Open Future. An interesting case study, she said, was Heartbleed. Researchers found that vulnerability and went through the appropriate vulnerability disclosure channels, but the information leaked although there was an embargo in place. In fact, the bug proofed to be exploited for a couple of months already. Microsoft, her former employer, had about ten years of a head start in developing a secure development life-cycle. The trick is, she said, to have plans in place in case of security vulnerabilities. You throw half of your plan away, anyway, but it’s good to have that practice of knowing who to talk to and all. She gave a few recommendations of which she thinks will enable us to write secure code. Coders should review, learn, and speak up if they feel uncomfortable with a piece of code. Managers could take up on what she called “smells” when people tend to be fearful about their code. Of course, MicroSoft’s SDL also contains many good practices. Her minimal set of practices is to have a self-assessment in place to determine if something needs security review, have an up-front threat modelling that is kept up to date as things evolve, have a security checklist like Mozilla’s or OWASP’s, and have security analysis built into CI process.

Ultimaker Releases Open Source Files for Ultimaker 2 Go and Extended

Filed under
OSS

For Dutch 3D printer manufacturer Ultimaker, being open sourced has been part of who the company was since the very beginning, and their early success can easily be traced directly back to their loyal community of users. Their first 3D printer, the Ultimaker Original, was already a great 3D printer and remains (despite being four years old) one of the most reliable 3D printers available today. And from the very beginning Ultimaker has encouraged their community to help them make the Original better, and they certainly have. In fact, many of the improvements created by the community for their personal Originals were implemented into their next 3D printer, the Ultimaker 2 and the resulting Ultimaker 2 family of 3D printers.

Two open source groups building separate software-defined networking (SDN) controllers are now part of the Linux Foundation, increasing the likelihood of cross-project collaboration.

This week, the Open Networking Lab (ON.Lab) placed its Open Networking Operating System (ONOS) project under the foundation. ONOS developers are building a carrier-grade SDN open source controller.

Imply launches with $2M to commercialize the Druid open-source data store

Filed under
OSS

Some of the first few people to work on the Druid open-source data store are today launching a new startup, Imply, with $2 million in seed funding from Khosla Ventures.

Think of this as the next big-data startup to spin out, in the vein of Hadoop-oriented Hortonworks (former Yahoo), Kafka startup Confluent (former LinkedIn), and Drill startup Dremio (former MapR). In this case, Imply is spinning out of advertising analytics startup Metamarkets.

OSS

lockchain technology company Coinprism has released Openchain, an open source, distributed permissioned ledger that targets enterprise and financial institutions.

Unlike bitcoin, which is based on a unique distributed ledger, Openchain will enable users to deploy their own version of the chain, allowing them to potentially cut costs and reduce settlement time.

My Free and Open Source Photography Workflow

OSS

After several years of trial and error, I finally have a complete RAW photography workflow in Linux that I am happy with.

The applications in this workflow aren’t just native to Linux, they are also free, open source software (FOSS). There is no need to dual boot, use WINE or a virtual machine. It’s a pure FOSS photography workflow running in Linux.

Open Source Tracked Robot Supports STEM in Africa

Filed under
OSS

We’d bet most Hackaday readers won’t need the software, anyway. The robot clearly uses RC servos for the drive and the little arm at the front, so controlling it directly from the Arduino ought to be easy enough. If you don’t want to roll your own, Senegal-based Azibot is taking preorders for kits for $99. We were a little surprised you couldn’t kick in a little more when you ordered to subsidize other kits for schools in need.

4MLinux 20.1 released.

This is a minor maintenance release in the 4MLinux STABLE channel. The release ships with the Linux kernel 4.4.34, which restores PAE support that "magically" disappeared in 4MLinux 20.0 (sorry :-). Additionally, some popular programs (Double Commander, Dropbox, Firefox, Java RE, Opera, PeaZip, Thunderbird, Wine) have been updated, too. Read more

Refracta 8.0 Is a Pint-Sized Powerhouse

Refracta is a somewhat obscure Linux distribution that offers exceptional functionality and stability. Obscurity is not always a bad thing when it comes to Linux distros. You can find some very worthwhile alternatives to your current operating system. Refracta is a big surprise in a small package. Many look-alike desktop distros are difficult to distinguish from run-of-the-mill garden varieties. Others offer new adopters something unique that makes using them fun and productive. Refracta is one of the few full-service Linux distros that makes an easy and more convenient replacement for pocket Linux options such as Puppy Linux. Not all Linux distros that install to a USB drive -- and have the ability to save files and system settings in a persistent mode -- work equally well. Read more

Clear Linux With Mesa 13 Is A Strong Match For Intel Linux Performance

When benchmarking Intel's Clear Linux distribution earlier this year we found its Intel graphics performance to be quite good and slightly faster than other Linux distributions even when Clear was using an older version of Mesa. Now with Clear Linux having switched to Mesa 13, I decided to run some fresh Intel OpenGL benchmarks on it compared to other distributions. Read more
