Servers: Docker Hub, Internet Archive, DevOps...

Mon, 2017-06-26 22:36
  • Building Images with Dockerfile and Docker Hub

    In this series previewing the self-paced Containers for Developers and Quality Assurance (LFS254) training course from The Linux Foundation, we’ve covered installing Docker, introduced Docker Machine, and some basic commands for performing Docker container and image operations. In the three sample videos below, we’ll take a look at Dockerfiles and Docker Hub.

    Docker can build an image by reading the build instructions from a file that’s generally referred to as Dockerfile. So, first, check your connectivity with the “dockerhost” and then create a folder called nginx. In that folder, we have created a file called dockerfile and in the dockerfile, we have used different instructions, like FROM, RUN, EXPOSE, and CMD.

  • What can developers learn from being on call?

    We often talk about being on call as being a bad thing. For example, the night before I wrote this my phone woke me up in the middle of the night because something went wrong on a computer. That’s no fun! I was grumpy.

    In this post, though, we’re going to talk about what you can learn from being on call and how it can make you a better software engineer!. And to learn from being on call you don’t necessarily need to get woken up in the middle of the night. By “being on call”, here, I mean “being responsible for your code when it breaks”. It could mean waking up to issues that happened overnight and needing to fix them during your workday!

  • Making the Internet Archive’s full text search faster.

    The Internet Archive is a nonprofit digital library based in San Francisco. It provides free public access to collections of digitized materials, including websites, books, documents, papers, newspapers, music, video and software.

    This article describes how we made the full-text organic search faster — without scaling horizontally — allowing our users to search in just a few seconds across our collection of 35 million documents containing books, magazine, newspapers, scientific papers, patents and much more.

  • DevOps: More Than Automation

    Type “devops” into any job search site today and the overwhelming majority of results will be for some variation of “DevOps Engineer”. The skills required will centre on tools like Puppet/Chef/Ansible, AWS/Azure, scripting in Python/Perl/Bash/PowerShell etc. Essentially, they’ve taken a deployment automation engineer role, crossed out “deployment automation” and written “DevOps” in its place.

How Linux and makerspaces can strengthen our social fabric

Mon, 2017-06-26 21:45

In recent years, we've seen the rise of makerspaces, a new social invention where people with shared interests, especially in STEAM (science, technology, engineering, art, and math), gather to work on projects and share ideas.

I was intrigued when I learned about a makerspace in my community, because I had never heard of such a concept before. I've since learned that makerspaces offer so much more than just a place to learn and build. A well-run makerspace also knits together a community and its social fabric—and, most importantly, invites in people who might otherwise be marginalized.

Lenovo Flex 11 Chromebook review: Tough, durable and inexpensive

Mon, 2017-06-26 20:10

The Lenovo Flex 11 Chromebook is a consumer version of Lenovo's very solid Chromebooks For Education products. It's built tough — rated to take a 2.4-foot drop and has a water resistant keyboard tray to keep spills out, but still comes in at a very reasonable $279.99. Finding a "rugged" Chromebook that's not EDU branded and uber-expensive isn't a common thing, so we were instantly interested.

After a bit of time with it, the strengths outweigh the drawbacks and we like the Flex 11. It's not the most powerful Chromebook we've tried but it wasn't made to be. It's a decent, solid performer designed to take more abuse than most other products in its class.

We think the durability factor and low price make the Flex 11 a great Chromebook for kids or someone who tends not to treat his or her stuff all that respectfully. And while the body is pretty darn durable, the keyboard leaves a lot to be desired. Read on for our full take.

Moto C Plus review: Buy it only for Stock Android

Mon, 2017-06-26 20:08

What is the Moto C Plus? Who is it aimed at? Lenovo claims that the C Plus is aimed at the youth who want an affordable smartphone with excellent battery life, the latest software, expandable storage and a premium design. So basically, the whole package. That is a pretty high standard to set.

So does the Moto C Plus succeed on these counts? It does achieve some of the goals Lenovo set out to achieve with it, but also stumbles quite a bit on others. The other challenge that the phone faces is the strong competition in this segment. There are phones like the Xiaomi Redmi 4, which seem to make all the right compromises in order to achieve their low price tag. So how does Motorola competes in the segment? The company is banking on the combination of stock Android and great battery life to help it fight. Does it succeed? Let's find out.

Dell Precision 5520 Developer Edition: An amazing Ubuntu mobile workstation

Mon, 2017-06-26 19:45

The transformation of Dell into Linux hardware maker is nothing short of extraordinary. It started in 2012, when Dell’s Project Sputnik started to offer Ubuntu pre-installed on specific developer-class laptops, like the Dell XPS series. Five years later, Dell is offering Ubuntu on an even broader array of PCs, including the gorgeous Precision series.

Dell’s Precision 5520 Ubuntu is a capable machine, with looks to match. But does this justify its astonishing pricetag, which depending on configuration, can soar past the $3,000 mark?

Hyperconverged infrastructure (HCI) is all the rage these days. But there are two primary means of achieving it that IT organizations need to consider.

Debian Linux reveals Intel Skylake and Kaby Lake processors have broken hyper-threading

Mon, 2017-06-26 19:33

Do you have an Intel Skylake and Kaby Lake processor under your computer's hood? Have you experienced unexplained application and system hiccups, data corruption, or data loss? It could be because your chipset has hyper-threading enabled and the chips are malfunctioning.

Henrique de Moraes Holschuh, a Debian Linux developer, revealed the Intel chip problem on the Debian developer list. Officially, Intel hasn't acknowledged the problem, but engineers at Dell and Intel have told me that the problem, and its fix, exists.

There are a lot of decisions to be made before enterprises are ready for production and deployment of container apps, asserts SUSE. To help enterprises derive full value from containerized apps and not "re-create the wheel", the SUSE engineering team is busy creating the next-generation application development and hosting platform for container applications and services.

How to use Evernote in Linux

Mon, 2017-06-26 19:26

The browser-based version of Evernote is the only officially supported way of using the application on Linux. It works, but if you’re a tab hoarder like me, editing your notes in a tab in a sea of tabs can be a bit tricky. On top of that, there is the additional baggage of running a full-fledged web browser.

Manjaro Gellivara was a great release! Now we are proud to announce v17.0.2, which fixes a lot of issues we had with our original release of Gellivara.

A Linux laptop with security at its core: Purism's Librem PCs now widely available

Mon, 2017-06-26 19:05

US laptop maker Purism has announced the general availability of its privacy-focused Librem 13 and Librem 15 laptops.

The laptops prioritize privacy, security, and open-source software, offering features such as dedicated camera and microphone kill switches, as well as its own Debian-based PureOS.

Latest From GNOME Builder and Older GNOME News (Catchup)

  • Code Search for GNOME Builder: Indexing

    Goal of Code Search for GNOME Builder is to provide ability to search all symbols in project fuzzily and jump to definition from reference of a symbol in GNOME Builder. For implementing these we need to have a database of declarations. So I created a plugin called ‘Indexer’ in Builder which will extract information regarding declarations and store them in a database.
