Open Source - ven, 09/18/2020 - 09:00

Wekan is an open source kanban board application that allows you to manage your daily tasks with (virtual) cards. You can create boards and cards and move them between columns as you make progress on each task. You can also add people who work with you to the tasks on the board. Like other kanban tools, Wekan also allows you to use colored labels on cards to facilitate grouping, filtering, and assigning them to specific people. Because Wekan is open source (distributed under an MIT License), it's easy to modify and use.

The Raspberry Pi is a small, versatile device that makes interfacing with the real world a breeze for mere mortals. The Raspberry Pi Foundation's idea was to sell the devices at such a low cost that breaking one would be sad—but not a disaster. This is one reason it has been a massive success as an educational tool. But their usefulness has not escaped the business world, where they are becoming a valuable tool for automating the physical world.

How Nextcloud simplified the signup process for decentralization

Open Source - lun, 09/14/2020 - 09:00

We always had a nice list of dozens of Nextcloud providers, yet the most common question I heard, even from technically apt friends of mine, was:

"Hi, Jan, umm…so, which Nextcloud provider do you recommend?"

Which is, of course, understandable. If you have a long list of providers, how do you choose? Hosted nearby? Cute name? Biggest logo?

Open Source - ven, 09/11/2020 - 09:02

Ok, I have just been doing some writing – something I do a lot of – and for some strange reason, I actually paid attention to the icon that stands for “Save.” It is – what?? – a diskette!! Why? How long has it been since diskettes were actually used? And how would the young people coming into computing even know what a diskette is?

How this open source test framework evolves with .NET

Open Source - jeu, 09/10/2020 - 09:01

A software project's design is a consequence of the time it was written. As circumstances change, it's wise to take a step back and consider whether old ideas still make for a good design.
