Get started with Freeplane, an open source mind mapping application

ven, 01/25/2019 - 09:03

There seems to be a mad rush at the beginning of every year to find ways to be more productive. New Year's resolutions, the itch to start the year off right, and of course, an "out with the old, in with the new" attitude all contribute to this. And the usual round of recommendations is heavily biased towards closed source and proprietary software. It doesn't have to be that way.

Here's the 13th of my picks for 19 new (or new-to-you) open source tools to help you be more productive in 2019.

ven, 01/25/2019 - 09:01

Python is a good beginner programming language. And games are a good beginner project: they are visual, self-motivating, and fun to show off to friends and family. However, the most common library to write games in Python, PyGame, can be frustrating for beginners because forgetting seemingly small details can easily lead to nothing rendering.

What does DevOps mean to you?

jeu, 01/24/2019 - 09:01

It's said if you ask 10 people about DevOps, you will get 12 answers. This is a result of the diversity in opinions and expectations around DevOps—not to mention the disparity in its practices.

To decipher the paradoxes around DevOps, we went to the people who know it the best—its top practitioners around the industry. These are people who have been around the horn, who know the ins and outs of technology, and who have practiced DevOps for years. Their viewpoints should encourage, stimulate, and provoke your thoughts around DevOps.

GStreamer WebRTC: A flexible solution to web-based media

mer, 01/23/2019 - 09:02

Currently, WebRTC.org is the most popular and feature-rich WebRTC implementation. It is used in Chrome and Firefox and works well for browsers, but the Native API and implementation have several shortcomings that make it a less-than-ideal choice for uses outside of browsers, including native apps, server applications, and internet of things (IoT) devices.

Organize your information on the Mac desktop with nvALT

mar, 01/22/2019 - 09:03

To be honest, I'm of two minds when it comes to using open source on closed platforms. I prefer to work on the open side of the fence, but I also understand you can't always do that. Especially at the dreaded day job or when you're working onsite as a contractor. You have to use the hardware your employer supplies.

Over the last few years, I've used a MacBook Pro at the office. When I'm in these types of situations, I try to load as much open source software on my office computer as I can without drawing the ire of the IT department.

Challenges in open source voice interfaces

mar, 01/22/2019 - 09:02

If you're anything like many open source enthusiasts, you may have grown up watching science fiction shows like Knight Rider, or Star Trek, or (my personal favorite) Time Trax. What do they have in common? In each, voice is the key medium through which the protagonists interact with a computer. Knight Rider had Kitt, Star Trek had the ubiquitous computer, and even the indefatigable Darrian Lambert in Time Trax had dependable Selma, the holographic assistant.

Open edX and OpenStack for complex learning environments

mar, 01/22/2019 - 09:01

Almost every new technology developed in recent years has been complex, distributed, and built for scale: Kubernetes, Ceph, and OpenStack are a few examples. These systems are quite different from the ones we saw just a few years ago. Practically any non-trivial software solution today comes with loose coupling, asynchronicity, and elasticity—properties usually absent from systems of the past.

Letting people work where they want shows how much you value them

mar, 01/22/2019 - 09:00

Open organizations are inclusive. They aren't inclusive solely because it's the right way to be but because it produces better outcomes. Inclusivitiy enables a more diverse set of viewpoints.

But in order for those views to be heard, they have to be given.That's why an open organization must embrace remote workers.

Booting Linux faster

lun, 01/21/2019 - 09:02

Of all the computers I've ever owned or used, the one that booted the quickest was from the 1980s; by the time your hand moved from the power switch to the keyboard, the BASIC interpreter was ready for your commands. Modern computers take anywhere from 15 seconds for a laptop to minutes for a small home server to boot. Why is there such a difference in boot times?

Solving the Year 2038 problem in the Linux kernel

lun, 01/21/2019 - 09:02

Because of the way time is represented in Linux, a signed 32-bit number can't support times beyond January 19, 2038 after 3:14:07 UTC. This Year 2038 (Y2038 or Y2K38) problem is about the time data type representation. The solution is to use 64-bit timestamps.
