Small businesses are ripe for free software

OSS

Once upon a time, in a career far, far away, I worked for a very small business. I was tasked with upgrading the OLD PC’s. The budget was so miniscule that literally every penny counted. In the effort to get the best bang for the buck, I stumbled across these programs called free software. “Whoo-hoo, they’re free” I thought. Little knowing how that introduction to free software applications would change my life.

OLPC: yet another bad idea

Filed under
OLPC

There are plenty of misguided projects which people in the West undertake, under the mistaken impression that they are helping those in the underdeveloped regions of the world.

The One Laptop Per Child initiative, a brainwave of MIT's Nicholas Negroponte, is just the latest in a long line. When you throw in fancy phrases like "bridging the digital divide" the publicity is ensured.

How can an operating system, Linux, which just so happens to be a free alternative to their costly #1 competitor, not be widespread and hugely successful? Linux is by far the greatest open source software available to any computer; yet, it struggles for many good reasons.

Linux: Page Replacement Design

Filed under
Linux

A university student studying operating systems asked about why the Linux kernel uses two chained lists in its LRU (least recently used) page replacement algorithm. Andrea Arcangeli, whose virtual memory subsystem was merged into the 2.4.10 kernel, explained, "back then I designed it with two lru lists because by splitting the active from the inactive cache allows to detect the cache pollution before it starts discarding the working set."

Test of current RealPlayer/HelixPlayer nightly builds

Filed under
Software

After I wondered what the current state of the HelixPlayer/RealPlayer development is I asked the developers. The answer was that there is still no date given, but that I could help them by testing the players in my setup. And since that isn’t difficult at all I downloaded the rpms and gave them a try.

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
