  • 3D Printed, Open Source Glia Stethoscope Receives Clinical Validation

    Dr. Tarek Loubani spent some time working in hospitals in the Gaza Strip during the worst of the chaos and violence that is unfortunately still going on there. Due to a long-standing blockade, medical supplies were scarce in the region – so scarce that doctors could often not find a stethoscope when they needed one. So Dr. Loubani came up with his own solution – he 3D printed a stethoscope, for about 30 cents.

7 Best Free and Open Source Ruby-Based Web Content Management Systems

A web content management system (WCMS) is software designed to simplify the publication of Web content. In particular, it enables content creators to submit content without requiring technical knowledge of HTML or the uploading of files. A CMS is most commonly used in creating an intranet or in establishing a presence on the Web. This type of software that keeps track of every piece of content on a Web site. Content can be simple text, photos, music, video, documents, or just about anything you can think of. A major advantage of using a CMS is that it requires almost no technical skill or knowledge to manage. Not only do content management systems help website users with content editing, they also take care of a lot of “behind the scenes” work such as automatically generating navigation elements, making content searchable and indexable, keeping track of users, their permissions and security setting, and much more. To provide an insight into the quality of software that is available, we have compiled a list of 7 high quality free Ruby-based Linux WCMS. Hopefully, there will be something of interest for anyone who wishes to manage a website. Read more

  • How to Set Up WireGuard VPN on Ubuntu 20.04 | Linuxize

    WireGuard is a modern VPN (Virtual Private Network) technology that utilizes state-of-the-art cryptography. Compared to other popular VPN solutions, such as IPsec and OpenVPN , WireGuard is faster, easier to configure, and has a smaller footprint. It is cross-platform and can run almost anywhere, including Linux, Windows, Android, and macOS. Wireguard is a peer-to-peer VPN; it does not use the client-server model.

Leaving Mozilla and Recalling One's Job in Mozilla

  • yoric.steps.next()

    The web is getting darker. It is being weaponized by trolls, bullies and bad actors and, as we’ve witnessed, this can have extremely grave consequences for individuals, groups, sometimes entire countries. So far, most of the counter-measures proposed by either governments or private actors are even scarier. The creators of the Matrix protocol have recently published the most promising plan I have seen. One that I believe stands a chance of making real headway in this fight, while respecting openness, decentralization, open-source and privacy. I have been offered the opportunity to work on this plan. For this reason, after 9 years as an employee at Mozilla, I’ll be moving to Element, where I’ll try and contribute to making the web a better place. My last day at Mozilla will be October 30th.

  • Working open source | daniel.haxx.se

    I work full time on open source and this is how. Background I started learning how to program in my teens, well over thirty years ago and I’ve worked as a software engineer and developer since the early 1990s. My first employment as a developer was in 1993. I’ve since worked for and with lots of companies and I’ve worked on a huge amount of (proprietary) software products and devices over many years. Meaning: I certainly didn’t start my life open source. I had to earn it. When I was 20 years old I did my (then mandatory) military service in Sweden. After having endured that, I applied to the university while at the same time I was offered a job at IBM. I hesitated, but took the job. I figured I could always go to university later – but life took other turns and I never did. I didn’t do a single day of university. I haven’t regretted it. [...]    I’d like to emphasize that I worked as a contract and consultant developer for many years (over 20!), primarily on proprietary software and custom solutions, before I managed to land myself a position where I could primarily write open source as part of my job. [...] My work setup with Mozilla made it possible for me to spend even more time on curl, apart from the (still going) two daily spare time hours. Nobody at Mozilla cared much about (my work with) curl and no one there even asked me about it. I worked on Firefox for a living. For anyone wanting to do open source as part of their work, getting a job at a company that already does a lot of open source is probably the best path forward. Even if that might not be easy either, and it might also mean that you would have to accept working on some open source projects that you might not yourself be completely sold on. In late 2018 I quit Mozilla, in part because I wanted to try to work with curl “for real” (and part other reasons that I’ll leave out here). curl was then already over twenty years old and was used more than ever before.
