Do Linux distributions still matter with containers?

12 hours 53 min ago
Some people say Linux distributions no longer matter with containers. Alternative approaches, like distroless and scratch containers, seem to be all the rage. It appears we are considering and making technology decisions based more on fashion sense and immediate emotional gratification than thinking through the secondary effects of our choices. We should be asking questions like: How will these choices affect maintenance six months down the road? What are the engineering tradeoffs? How does this paradigm shift affect our build systems at scale?read more

Cat-Proofing Your Screen Locker with Bash

Thursday 21st of February 2019 02:32:18 AM
by Mitch Frazier  I have a computer in my bedroom. I also have cats. Unfortunately, cats and screen lockers don't mix well, particularly at night. To be accurate, it's more a problem with the display power management than the actual screen locking. Here's the way it works: I run a script to "shut the lights off at night" (that is, lock the screen and force the display to power down), and that works great, until one of the cats jumps on the desk and causes the mouse to move and turn the display back on. And the cats don't even have to touch the mouse; the slight movement of the desk is enough to cause the mouse to react. Recently, I'd had enough of it and figured there had to be a way to disable the mouse and "refactor" the script. Go to Full Article

Infrastructure monitoring: Defense against surprise downtime

Wednesday 20th of February 2019 08:51:54 PM
Infrastructure monitoring is an integral part of infrastructure management. It is an IT manager's first line of defense against surprise downtime. Severe issues can inject considerable downtime to live infrastructure, sometimes causing heavy loss of money and material.Monitoring collects time-series data from your infrastructure so it can be analyzed to predict upcoming issues with the infrastructure and its underlying components. This gives the IT manager or support staff time to prepare and apply a resolution before a problem occurs.A good monitoring system provides:read more

Server: HTTP Clients, IIS DDoS and 'DevOps' Hype From Red Hat

  • What are good command line HTTP clients?
    The whole is greater than the sum of its parts is a very famous quote from Aristotle, a Greek philosopher and scientist. This quote is particularly pertinent to Linux. In my view, one of Linux’s biggest strengths is its synergy. The usefulness of Linux doesn’t derive only from the huge raft of open source (command line) utilities. Instead, it’s the synergy generated by using them together, sometimes in conjunction with larger applications. The Unix philosophy spawned a “software tools” movement which focused on developing concise, basic, clear, modular and extensible code that can be used for other projects. This philosophy remains an important element for many Linux projects. Good open source developers writing utilities seek to make sure the utility does its job as well as possible, and work well with other utilities. The goal is that users have a handful of tools, each of which seeks to excel at one thing. Some utilities work well independently. This article looks at 4 open source command line HTTP clients. These clients let you download files over the internet from the command line. But they can also be used for many more interesting purposes such as testing, debugging and interacting with HTTP servers and web applications. Working with HTTP from the command-line is a worthwhile skill for HTTP architects and API designers. If you need to play around with an API, HTTPie and curl will be invaluable.

  • 5 things to master to be a DevOps engineer
    There's an increasing global demand for DevOps professionals, IT pros who are skilled in software development and operations. In fact, the Linux Foundation's Open Source Jobs Report ranked DevOps as the most in-demand skill, and DevOps career opportunities are thriving worldwide. The main focus of DevOps is bridging the gap between development and operations teams by reducing painful handoffs and increasing collaboration. This is not accomplished by making developers work on operations tasks nor by making system administrators work on development tasks. Instead, both of these roles are replaced by a single role, DevOps, that works on tasks within a cooperative team. As Dave Zwieback wrote in DevOps Hiring, "organizations that have embraced DevOps need people who would naturally resist organization silos."

Purism's Privacy and Security-Focused Librem 5 Linux Phone to Arrive in Q3 2019

Initially planned to ship in early 2019, the revolutionary Librem 5 mobile phone was delayed for April 2019, but now it suffered just one more delay due to the CPU choices the development team had to make to deliver a stable and reliable device that won't heat up or discharge too quickly. Purism had to choose between the i.MX8M Quad or the i.MX8M Mini processors for their Librem 5 Linux-powered smartphone, but after many trials and errors they decided to go with the i.MX8M Quad CPU as manufacturer NXP recently released a new software stack solving all previous power consumption and heating issues.

Hack Week - Browsersync integration for Online

Recently my LibreOffice work is mostly focused on the Online. It's nice to see how it is growing with new features and has better UI. But when I was working on improving toolbars (eg. folding menubar or reorganization of items) I noticed one annoying thing from the developer perspective. After every small change, I had to restart the server to provide updated content for the browser. It takes few seconds for switching windows, killing old server then running new one which requires some tests to be passed. Last week during the Hack Week funded by Collabora Productivity I was able to work on my own projects. It was a good opportunity for me to try to improve the process mentioned above. I've heard previously about browsersync so I decided to try it out. It is a tool which can automatically reload used .css and .js files in all browser sessions after change detection. To make it work browsersync can start proxy server watching files on the original server and sending events to the browser clients if needed. Read more
