Anatomy of a perfect pull request

4 hours 54 min ago

Writing clean code is just one of many factors you should care about when creating a pull request.

Large pull requests cause a big overhead during the code review and can facilitate bugs in the codebase.

Where in the DevOps cycle do you do security?

4 hours 56 min ago

Sometimes the title just gives away the answer. I’m a security guy, so this one is easy for me: the answer to "Where in the DevOps cycle do you do security?" is "everywhere". However, a couple of sentences doesn’t make a very compelling article, so I’ll go into a bit more detail.

A summer reading list for open organization enthusiasts

Tuesday 19th of June 2018 07:02:00 AM

The books on this year's open organization reading list crystallize so much of what makes "open" work: Honesty, authenticity, trust, and the courage to question those status quo arrangements that prevent us from achieving our potential by working powerfully together.

These nine books—each one a recommendation from a member of our community—represent merely the beginning of an important journey toward greater and better openness.

But they sure are a great place to start.

Tuesday 19th of June 2018 07:00:00 AM

In this article, we'll take a quick look at how to reset, revert, and completely return to previous states, all with the simplicity and elegance of individual Git commands.

5 open source alternatives to Dropbox

Monday 18th of June 2018 07:02:00 AM

Dropbox is the 800-pound gorilla of filesharing applications. Even though it's a massively popular tool, you may choose to use an alternative.

Maybe that's because you're dedicated to the open source way for all the good reasons, including security and freedom, or possibly you've been spooked by data breaches. Or perhaps the pricing plan doesn't work out in your favor for the amount of storage you actually need.

BLUI: An easy way to create game UI

Friday 15th of June 2018 07:02:00 AM

Game development engines have become increasingly accessible in the last few years. Engines like Unity, which has always been free to use, and Unreal, which recently switched from a subscription-based service to a free service, allow independent developers access to the same industry-standard tools used by AAA publishers. While neither of these engines is open source, each has enabled the growth of open source ecosystems around it.

4 tools for building embedded Linux systems

Friday 15th of June 2018 07:01:00 AM

Linux is being deployed into a much wider array of devices than Linus Torvalds anticipated when he was working on it in his dorm room. The variety of supported chip architectures is astounding and has led to Linux in devices large and small; from huge IBM mainframes to tiny devices no bigger than their connection ports and everything in between. It is used in large enterprise data centers, internet infrastructure devices, and personal development systems.

Emacs, Vim, or something else?

Thursday 14th of June 2018 07:03:00 AM

Some topics are just bound to bring about a roaring argument spirited intellectual discussion. At the dinner table, it might be religion or politics. But among open source users, aside from asking about preferred Linux distributions, the next most rabblerousing stimulating question is likely around what text editor you prefer.

Purple testing and chaos engineering in security experimentation

Thursday 14th of June 2018 07:01:00 AM

The way we use technology to construct products and services is constantly evolving, at a rate that is difficult to comprehend. Regrettably, the predominant approach used to secure design methodology is preventative, which means we are designing stateful security in a stateless world. The way we design, implement, and instrument security has not kept pace with modern product engineering techniques such as continuous delivery and complex distributed systems.

Debian GNU/Linux 10 "Buster" Installer Updated with Linux Kernel 4.16 Support

Developed under the Debian Testing umbrella, the forthcoming Debian GNU/Linux 10 "Buster" operating system series just received today the third alpha milestone of its installer, which lets people install the Linux-based operating system on their personal computers, servers, and IoT devices, such as the Raspberry Pi. One of the most interesting changes that caught out eyes is the bump of the kernel support from Linux kernel 4.13, which was used in the second alpha build, to Linux kernel 4.16. Of course, this means that there's better hardware support, so chances are you'll be able to install the development version of Debian GNU/Linux 10 "Buster" on newer machines or if you have some exotic components on your PC.

  • Microsoft ICE Contract Draws Fire

First Ubuntu Touch OTA-4 Release Candidate Based on Ubuntu 16.04 LTS Is Here

The latest Ubuntu Touch update from UBports, OTA-3, was released last year near the Christmas holidays, but it was still based on Ubuntu 15.04 (Vivid Vervet), so if you though Ubuntu Phones are dead, think again, because the UBports team has been hard at work to bring you the OTA-4, which will be the first to rebase the operating system on Ubuntu 16.04 LTS (Xenial Xerus). "The main reason why the arrival of OTA-4 seemed to take so long is because Ubuntu Touch switched its base to Ubuntu 16.04 LTS Xenial Xerus. This is a mammoth milestone for the project, because it allowed us to transition from the unsupported Ubuntu 15.04 Vivid Vervet to a Long Term Support (LTS) base," reads today's announcement.
