This month on The Queue, hydrurga from LinuxQuestions.org asks: How can I phrase my technical question well in order to increase the chances of having it answered? The answer Another great question that I frequently see asked. Keep filling The Queue with quality submissions. read more

While I typically go all out for Halloween decorations every year, I'll admit I'm feeling tired this year. I still wanted to delight the neighborhood kids with simple details, so I decided to make lighted bags for my front porch railing this year. If you are someone who has a paper cutting machine like the Silhouette, this project will likely be a lot easier. Simply import the SVG file, resize for whatever size box you want, cut out, and assemble. However, for those of you who don't have one, I've included instructions on how to make this project without any machine at all. read more

Gene Kim thinks he has at least one thing in common with George R.R. Martin: They both take their sweet time writing highly-anticipated sequels. In Kim's case, however, the wait is over. Kim's particular song of fire and ice—or rather, two equally opposing forces, "dev" and "ops"—continues this month. read more

Kees Cook is a Google techie and security researcher whose interests include the Linux Kernel Self Protection Project. The idea of "self-protection" doesn't mean giving up on trying to create secure code in the first place, of course.

If you cycled the clock back about 15 years and surveyed the prevailing beliefs about open source technology at the time, you would find nowhere near the volume of welcome for it that we see today. As a classic example, The Register reported all the way back in 2001 that former CEO of Microsoft Steve Ballmer made the following famous statement in a Chicago Sun-Times interview: "Linux is a cancer that attaches itself in an intellectual property sense to everything it touches."

For DevOps, installation is one of the major tasks. People may think package installation is pretty straightforward and easy now: Just run commands like apt-get, yum, brew, etc. Or simply leave it to containers. Is it really that easy? Here is a list of headaches and hidden costs.

Cloud companies like to talk about about how you can avoid vendor lock-in. And OpenStack just showed how to make it happen. Sixteen different vendors did a live demo at OpenStack Summit showing that you could run the same software stack on 16 separate OpenStack platforms.

HPE still supports OpenStack in its Helion cloud program, but it's cutting way back on how much it's spending on helping create OpenStack.

Congatec announced three Linux-friendly COMs based on Intel’s new Atom E3900 SoC: a Qseven, a COM Express Compact, and one of the first SMARC 2.0 modules. Congatec is one of the first vendors to announce a major product lineup based on Intel’s newly announced, 14nm-fabricated Atom E3900 “Apollo Lake” SoCs.

I've looked at general astronomy programs in the past that are helpful for many tasks you might need to do in your stargazing career. But, several specific jobs are more complicated and require specialized software to make relevant calculations, so here, let's take a look at Nightfall.

Over the past decade, the majority of new open source OS projects have shifted from the mobile market to the Internet of Things. In this fifth article in our IoT series, we look at the many new open source operating systems that target IoT.

ARM launched its first Cortex-M MCUs with ARMv8-M and TrustZone security: the tiny, low-power Cortex-M23 and faster Cortex-M33. At the ARM TechCon show in Santa Clara, ARM unveiled two new Cortex-M microprocessors that will likely emerge as major Internet of Things workhorses over the coming decade, supplanting most existing Cortex-M designs. The Cortex-M23 and Cortex-M33 […]

In this tutorial, I will show you how to build your own chat server using Rocket.Chat. I will use the latest Ubuntu LTS 16.04 server for the installation and Nginx as reverse proxy for the Rocket.Chat application. Rocket.Chat is a free and open source online chat solution for team communication, it allows you to build your own slack like online chat.

In part one of this series, I covered my top five reasons to love Kubernetes, the open source container orchestration platform created by Google. Kubernetes was donated to the Cloud Native Computing Foundation in July of 2015, where it is now under development by dozens of companies including Canonical, CoreOS, Red Hat, and more.

The future looks bright for OpenStack -- according to 451 Research, the company is growing rapidly to become a $5-billion-a-year cloud business. But obstacles still remain.

LinkSprite’s $25, 64 x 50mm “pcDuino4 Nano” SBC is a re-spin of FriendlyARM’s NanoPi M1, offering a quad-core H3, Raspberry Pi expansion, and 3x USB ports. Can you be a pcDuino without the Duino? For its latest open source pcDuino board, LinkSprite has switched from Arduino compatibility to a 40-pin Raspberry Pi expansion interface, breaking […]

Let’s talk about how to start to develop network applications for ESP8266 chip using Mongoose Embedded Web Server in Linux. I will use Ubuntu, but all things can be easily adapted for any Linux distribution.
