  • Jonathan Carter: Running for DPL

    I am running for Debian Project Leader, my official platform is published on the Debian website (currently looks a bit weird, but a fix is pending publication), with a more readable version available on my website as well as a plain-text version.

    Shortly after I finished writing the first version of my platform page, I discovered an old talk from Ian Murdock at Microsoft Research where he said something that resonated well with me, and I think also my platform.

  • Stephen Michael Kellat: Middle of March Meandering

    Eventually I intend to try Ubuntu Server installations to the three idle Raspberry Pi 3B+ boards. The ultimate goal there is for being able to offload video transcoding.

  • Two-thirds of Android antivirus apps are worthless or worse

    Yes, you may as well change your wallpaper to say "no viruses allowed:" it'd be just as effective as the 170 antivirus products that detected fewer than 30 per cent of the 2000 malicious apps installed for testing purposes.

  • Why foldable smartphones are more fad than forever devices

    I've been a part of many industries and, without fail, each industry eventually resorts to gimmicks to sell a product. In some instances, the gimmick convinces consumers that the new product and is the must-have of the industry.

    [...]

    The smartphone industry is no stranger to such snake-oil salesmanship. We've seen pop-up selfie cameras, Samsung Air View, built-in projectors, the HTC kickstand, the Amazon Fire Phone, the Ubuntu Phone, LG Modules, smart scroll, Alcatel disco lights, Blackberry Storm, Samsung edge display, KnockOn Password, HTC U11, and Pixel squeezable sides.

    The point being, the smartphone industry is keen on bringing to light a plethora of gimmicks to try and woo users away from their current devices.

  • foss-north 2019: Training Day

    The 2019 incarnation of foss-north is less than a month away. This year we’re extending the conference in two directions: a training day and a community day. This time, I wanted to write about the training day.

    The training day, April 10, is an additional day for those who want to extend
    the conference with a day of dedicated training. I’m very happy to have two experienced and well known trainers on side: Michael Kerrisk and Chris Simmonds. Both has years of training experience.

    Michael will teach about the details in dynamic linking. The topic may seem trivial, but when you start scratching the surface, there are a lot of details to discover such as how to handle version compatibility, how symbol resolution really works, and so on. You can read more about the Building and Using Shared Libraries on Linux training here.

  • Your guide to LibrePlanet 2019, March 23-24!

    Are you planning on joining us for LibrePlanet 2019, coming up this weekend, March 23-24, at the Stata Center, Massachusetts Institute of Technology (MIT)? If you haven't registered yet, there's still time -- registration is open through Tuesday, March 19 at 10:00 EDT, and we also welcome walk-ins (space permitting)! Remember, students and Free Software Foundation (FSF) associate members get in gratis.

    We also hope you'll join us for the Friday night open house at the FSF office, here in Boston -- you can pick up your badge early to skip the line Saturday morning (more details below).

  • Will this new openness to open source heed past lessons?

     

    We set out to demonstrate how open source could work in the NHS for both vendors and users, and to dispel many of the myths that existed about open source. We created the NHS Open Source Foundation (now The Apperta Foundation), a not-for-profit designed to act as a custodian for quality assured NHS open source software, adapting the model developed by OSERA in the US for VistA.
     

    We identified a number of issues which we worked hard to address.

  • France’s economic council wants a greater European role for free software

     

    The European Union should encourage the use of free software, for example by setting quotas in public procurement and financing its development, says France’s Economic, Social and Environmental Council (Conseil économique, social et environnemental, or CESE). The constitutional consultative assembly sees free software, sharing and reuse as strategic parts of the European digital culture.

  • Release of Opinion Paper on Open Source and FRAND by OFA Fellow Simon Phipps

    The question if Open Source Software can be combined with a FRAND (fair, reasonable, and non-discriminatory) regime is often at the centre of the debate. Possibly, this question though is not the deciding one, as such a legal compatibility would require that Open Source developers would collaborate under such a regime.

    OpenForum Europe is very excited to publish the Opinion Paper by OFA Fellow and President of the Open Source Initiative, Simon Phipps. In this paper Simon posits that the core issue of Open Source Software and FRAND is not a legal one, but that Open Source developers will not collaborate under a FRAND regime.

Security: Updates, "US Huawei Blackballing Efforts" and Microsoft's Back Doors Keep Crackers Busy

  • US Huawei Blackballing Efforts Stall Due To Lack Of 'Actual Facts'

    During the Trump era, the US government has dramatically ramped up claims that Chinese hardware vendor Huawei is a nefarious spy for the Chinese government, blackballing it from the U.S. telecom market. From pressuring U.S. carriers to drop plans to sell Huawei phones to the FCC's decision to ban companies from using Huawei gear if they want to receive federal subsidies, this effort hasn't been subtle.

    While Huawei should never be confused with a saint (what telecom company would be?) there's several problems with the effort. The biggest being that despite a decade of hand-wringing and one eighteen month investigation by the US government, there's still no public evidence Huawei uses its network gear to spy on Americans. That's not sitting well with countries we've asked to join along in the fun.

  • Sorry, Linux. We know you want to be popular, but cyber-crooks are all about Microsoft for now

    Eight out of the ten most exploited vulnerabilities tracked by threat intelligence biz Recorded Future in 2018 targeted Microsoft products – though number two on its list was, surprise surprise, a Flash flaw.

    The most exploited vuln in the firm's hall of shame was a remote code execution flaw in Windows' VBScript engine that could pwn users who opened a booby-trapped web page with Internet Explorer.

    "Exploit kits associated with this vulnerability were noted to spread the malware Trickbot through phishing attacks," said Recorded Future in a report published today.

    The Flash vuln was none other than one exploited by North Korean state-backed hackers – first detected by South Korea's CERT, which discovered a flood of booby-trapped MS Office documents, web pages, spam messages and more.

    Orbital is an open-source project providing a virtualization-based PlayStation 4 emulator that is still in its early stages but what interests us is its technical details including the use of Vulkan/SPIR-V.

    Orbital leverages QEMU and other open-source components. At this stage it's not running any PS4 games but is able to boot into safe mode on PS4 5.xx kernels.

  • Cataclysm - Dark Days Ahead, a free and open source turn-based survival game had a huge update

    It occurred to me today, that no one here at GOL seems to have ever written about the free and open source turn-based survival game Cataclysm - Dark Days Ahead.

    Okay, so what is it? A classic roguelike with a survival theme, set in a post-apocalyptic procedurally generated world.

  • System Shock 3 may see Linux support, OtherSide still working on Underworld Ascendant for Linux

    OtherSide Entertainment have teased out a new short video of System Shock 3 and it may see Linux support.

    Not to be confused with the crowdfunded System Shock reboot that Nightdive Studios are currently working on. System Shock 3 is being made with some of the original team behind the first two games as well like Warren Spector, so it should remain faithful to the series while being a rather nice upgrade in visuals.

  • Today’s Firefox Aims to Reduce Your Online Annoyances

    Almost a hundred years ago, John Maynard Keyes suggested that the industrial revolution would effectively end work for humans within a couple of generations, and our biggest challenge would be figuring what to do with that time. That definitely hasn’t happened, and we always seem to have lots to do, much of it online. When you’re on the web, you’re trying to get stuff done, and therefore online annoyances are just annoyances. Whether it’s autoplaying videos, page jumps or finding a topic within all your multiple tabs, Firefox can help. Today’s Firefox release minimizes those online inconveniences, and puts you back in control.

Firefox has supported Web Authentication for all desktop platforms since version 60, but Windows 10 marks our first platform to support the new FIDO2 “passwordless” capabilities for Web Authentication.

Lessons in Vendor Lock-in: 3D Printers

Filed under
OSS

One interesting thing about the hobbyist 3D printing market is that it was founded on free software and open hardware ideals starting with the RepRap project. The idea behind that project was to design a 3D printer from off-the-shelf parts that could print as many of its own parts as possible (especially more complex, custom parts like gears). Because of this, the first generation of 3D printers were all homemade using Arduinos, stepper motors, 3D-printed gears and hardware you could find in the local hardware store.

As the movement grew, a few individuals started small businesses selling 3D printer kits that collected all the hardware plus the 3D printed parts and electronics for you to assemble at home. Later, these kits turned into fully assembled and supported printers, and after the successful Printrbot kickstarter campaign, the race was on to create cheaper and more user-friendly printers with each iteration. Sites like Thingiverse and YouMagine allowed people to create and share their designs, so even if you didn't have any design skills yourself, you could download and print everyone else's. These sites even provided the hardware diagrams for some of the more popular 3D printers. The Free Software ethos was everywhere you looked.

Introducing flat-manager

Filed under
Red Hat

A long time ago I wrote a blog post about how to maintain a Flatpak repository.

It is still a nice, mostly up to date, description of how Flatpak repositories work. However, it doesn’t really have a great answer to the issue called syncing updates in the post. In other words, it really is more about how to maintain a repository on one machine.

In practice, at least on a larger scale (like e.g. Flathub) you don’t want to do all the work on a single machine like this. Instead you have an entire build-system where the repository is the last piece.

    Announced on Monday was that the US Department of Energy in cooperation with Argonne National Laboratory will see the "Aurora" supercomputer as the first US Exascale SC coming online in 2021 and featuring Intel's highly anticipated Xe Graphics.

    The Intel Xe Graphics are expected to put Aurora over the edge in being the first exascale super computer at least within the United States. Aurora will also feature Optane persistent DIMMs and next-generation Xeon processors. Intel is partnered with Cray on this design for the half a billion USD super computer.

  • Career advice for engineers: Step away from the keyboard

    Over the course of my career, I've had two to three major mindset shifts in how I approach my work. At first, I just focused on engineering—trying to know the most about whatever language or libraries I was using, being very "trivia" focused, and ultimately ignoring the concerns of others in an effort to just write good code. This wasn't to say I didn't try to get along with my coworkers or help them out, but my efforts to improve were all about me; after all, the team and the company do better as I become better. And to be fair, this approach isn't totally unfounded in its merits. As engineers, we must constantly evolve, learn more, and improve because the industry is getting harder with bigger problems that need more technical solutions every day. This approach worked well enough for me for the first half of my career, where I was junior enough to have such selfish (albeit well-meaning) motivations.

    Then I took a job where I worked with more engineers in one office than I had worked with in my entire career to date. This job nearly broke me. I went from being one of the better people in my role to barely scraping by… for nearly two years. I struggled to succeed, I constantly felt outclassed by the people around me, and many days I couldn't figure out why they even hired me (a feeling, it turns out, that some of my co-workers shared). But there was no big epiphany, no single defining moment that turned it around. Just a series of hard, abject failures from which I had two choices—give up or learn and grow. I did my best to do the latter. As I moved back to a smaller startup, I saw firsthand just how important it is to cement a culture, from the ground up, based around these lessons.

    My final mindset shift happened when I transitioned into management after the startup was acquired by a larger company. I didn't choose to be a manager; management chose me, in that I was offered the position. I was also told that, while everyone really believed in me, the ultimate reason they chose me was that they felt it would be less tumultuous to promote someone from within than hiring someone from outside. We had a very aggressive timeframe after the acquisition, and my new company didn't want to risk things by bringing in an outside leader who didn't have the team's trust. I found that this phase reinforced everything I had learned before about being effective in an engineering role—and turned up the dial on how hard I need to apply these lessons every minute of every day.

  • Why you should take the jobs no one else wants

    So often, we describe open organizations as places overflowing with highly engaged people—places where leaders emerge spontaneously to tackle urgent problems, where people opt-in to challenging initiatives they know they can influence and drive, where teams act with initiative and few top-down mandates.

    And it's all true. I see it regularly at Red Hat.

  • Contribution opportunity! Quick docs!

    Quick docs are meant to be short articles on the official Fedora documentation site that cover commonly used workflows/tools.

    Unlike wiki pages which are generally unreviewed, information on quick-docs follows the PR (peer-review + pull request) process. So the new information that is added there is more trustworthy and should be too, given that quick docs is listed on the official Fedora documentation website.

  • We did it again – Our HA solution is SAP Certified

    One of the main differences is that the new setup is now also supported for clusters with more than two nodes (n>2). We recommend to use an odd number of nodes to guarantee that always a majority of the cluster could proceed after cluster separations.

16 Best Free Linux Medical Imaging Software

Filed under
Software

Medical imaging is an essential, non-invasive, routine activity performed by radiographers and radiologic technologists. It’s a discipline of the health profession which involves using technology to capture images of the human body.

There are a number of reasons why capturing these images are important to our well-being. First, the images help in the identification and examination of diseases, and physical injuries such as broken bones and ruptured blood vessels, as well as assisting in diagnosing suitable treatments. Medical imaging is also crucial in an educational role.

Imaging capturing devices for medical purposes use the DICOM image format. DICOM is an acronym for Digital Imaging and Communications in Medicine. It’s the standard open image format used to handle, store, print and transmit information in medical imaging. This article focuses on software that lets you view images generated from DICOM devices.

Fedora 31 Preparing To Start Removing Packages Depending Upon Python 2

Python 2 support will formally reach end-of-life on 1 January 2020 and Fedora 31 is preparing for that by working to drop packages (or parts of packages) that depend upon Python 2. Fedora has been pushing for a Python 2 to Python 3 migration for many cycles now -- as most Linux distributions have -- while with Fedora 31 they are planning a "mass Python 2 package removal" if necessary. They are planning to closely track the state of packages depending upon Python 2 to either drop the packages or allow packagers to easily abandon Python 2 parts of programs. Read more
