Getting Back to Coding

Reducing tool complexity requires mercilessly applying YAGNI to your toolchain. Resist the siren songs of new, popular memes and the blandishments of vendors, and choose the tools that deliver only what you need.

When Metrics Go Wrong - how to avoid bad metrics in open source projects

Metrics are great. They can give you situational awareness about what's going on in your community, help you identify issues that you need to fix, and prove the effectiveness (or lack thereof) of community initiatives. But sometimes things go wrong.

  • Story Type: Editorial; Groups: Cloud
For a time, Amazon Web Services was the only cloud infrastructure game in town, but it didn't take long for the big boys like Google, Microsoft and IBM to recognize a good thing when they see it. And while AWS continues to grow, it's feeling the competition and price cuts are eroding profits.

Tiny Raspberry Pi-compatible SBC targets wearables

Hardkernel launched a $30, 60 x 36mm Raspberry-Pi compatible “Odroid-W” wearables oriented SBC, adding eMMC, ADC, RTC, a fuel gauge, and step converters. Hardkernel’s Odroid project developed the Odroid-W (Odroid-Wearable) for a partner’s Internet of Things prototyping platform, after first considering and dismissing its quad-core Odroid-U3 single board computer. The Odroid-U3, which was rated as the third most popular Linux hacker SBC in our recent survey, used too much power for use as an IoT and wearables platform. The Raspberry Pi was more power efficient, but too large. No doubt, RPi compatibility also had its attractions, as the project ended up building its own Raspberry Pi pseudo-clone implemented on a COM (computer-on-module) style form factor.

Who's using Docker?

I've spent the last couple of months working an internship for The Linux Foundation, doing research on new developments and adoption trends in the open source industry. If you have spent any amount of time reading about open source over the last year, you have probably heard about Docker; a lot of people are talking about it these days and the impact it's going to have on virtualization and DevOps. read more

Reglue: Opening Up the World to Deserving Kids, One Linux Computer at a Time

They say you never forget your first computer. For some of us, it was a Commodore 64 or an Apple IIe. For others, it was a Pentium 233 running Windows 95. Regardless of the hardware, the fond memories of wonder and excitement are universal. For me, I'll never forget the night my father brought home our first computer, a Tandy 1000.

6 open source tools for data journalism

  • Opensource.com (Posted by bob on Jul 29, 2014 12:29 PM EDT)
  • Story Type: News Story
When I was in journalism school back in the late 1980s, gathering data for a story usually involved hours of poring over printed documents or microfiche. A lot has changed since then. While printed resources are still useful, more and more information is available to journalists on the web. That’s helped fuel a boom in what’s come to be known as data journalism. At its most basic, data journalism is the act of finding and telling stories using data—like census data, crime statistics, demographics, and more. read more

Hybrid RAID 1 (Mirror) of RAM drive & SATA HDD Using LVM with LUKS [and systemd unit file] on Fedora Linux

Hybrid RAID 1 (Mirror) of RAM drive & SATA HDD Using LVM with LUKS [and systemd unit file] on Fedora Linux The IT industry has a continual balance between security and usability. Within this balance, performance usually affects usability. In the realm of protecting "Data at Rest" (i.e. encryption) one may find three factors affecting performance, and therefore usabilty: The harddrive, CPU and RAM. Of these, the harddrive will always prove to be a bottleneck (yes, even with an SDD). Free Software has a rather elegant solution for protecting Data at Rest, called Linux Unified Key Setup (LUKS). In the spirit of "Freedom 0: The freedom to run the program for any purpose." please enjoy my contribution to our collective knowledgebase of a solution to the fascinating problem of "how can we speed up encyption"?

Cloudy CoreOS Linux distro declares itself production-ready

The developers behind the stripped-down CoreOS Linux distribution have pushed version 367.1.0 to the Stable release channel, marking the first time the project has delivered a production-ready release. Unlike other Linux distros, CoreOS is a minimal OS that ships each new version as a single unit, rather than updating individual software packages. Updates are pushed to users via "channels," similar to how web browser vendors deliver their releases.
