  • Test and Code: 84: CircuitPython - Scott Shawcroft

    The combination of Python's ease of use and Adafruit's super cool hardware and a focus on a successful beginner experience makes learning to write code that controls hardware super fun.

    In this episode, Scott Shawcroft, the project lead, talks about the past, present, and future of CircuitPython, and discusses the focus on the beginner.

    We also discuss contributing to the project, testing CircuitPython, and many of the cool projects and hardware boards that can use CircuitPython, and Blinka, a library to allow you to use "CircuitPython APIs for non-CircuitPython versions of Python such as CPython on Linux and MicroPython," including Raspberry Pi.

  • 10 Linux distros: From different to dangerous

    One of the great benefits of Linux is the ability to roll your own. Throughout the years, individuals, organizations, and even nation states have done just that. In this gallery, we're going to showcase some of those distros. Be careful, though. You may not want to load these, or if you do, put them in isolated VMs. We're not kidding when we say they could be dangerous.

Linux Candy: WallGen – image generator tool

Software

Who loves eye candy? Don’t be shy — you can raise both hands!!

Linux Candy is a new series of articles covering interesting eye candy software. We’re only going to feature open-source software in this series.

I’m not going to harp on about the tired proverb “All work and no play makes Jack a dull boy”. But there’s a certain element of truth here. If you spend all day coding neural networks, mastering a new programming language, sit in meetings feeling bored witless, you’ll need some relief at the end of the day. And what better way by making your desktop environment a bit more memorable.

Let’s start our candy adventure with WallGen. It’s a small command-line utility that generates HQ poly wallpapers with only a few text arguments for inputs. Depending on these arguments, you can create shape-based patterns, randomly filled surfaces, and even image-based patterns.

Review: AcademiX GNU/Linux 2.2

Filed under
GNU
Linux
Reviews

What sets AcademiX apart from other distributions is the EDU software manager. This package manager provides curated lists of educational software, which are grouped by subject and by age range. This package manager makes finding educational software really easy. There is software for astronomy, biology, geography, foreign languages, and many other subjects. While there are gaps in the availability of applications covering various subjects, that is a gap in the broader open source application ecosystem, not something specific to AcademiX. While some of the rough edges I noted with the installation process and the desktop customization make me a hesitant to recommend AcademiX to new Linux users, Educational Technology professionals should perhaps try out AcademiX just to use the EDU package manager to explore various open source applications.

While installing and updating software was easy and basically the same experience as any other modern, Debian-based distribution, the fact that some of the packages come from servers in Romania means that some package downloads can be much slower than downloading from the world-wide network of Debian mirrors. For individual packages and small collections of packages this is not too noticeable, but it is still an issue. The frustrating part is the fact that the speeds are not consistent. Sometimes I was downloading at only 40kbps, but other times it was much faster. I experienced the same issue when trying to download the ISO. One download took about 20 minutes for the 1.7GB image but some other attempts took 4 hours.

Final thoughts

AcademiX GNU/Linux is an interesting distribution, but it has some rough edges that need to be cleaned up. Honestly, I really, really wanted to like this distribution (good distributions aimed at the educational market are always needed), but found it to be merely okay. AcademiX has a lot of potential, but it is just not there yet. DebianEdu/Skolelinux is far more polished while serving almost the exact same niche. However, if the AcademiX team cleans up some of the issues I noted above, especially the installer issues, I think future versions of AcademiX might turn out to be worthwhile. The EDU software installer is well organized and aids in discovering educational software, so that is one solid advantage AcademiX offers, but overall the distribution needs more work and polish before I could move it from "this distribution is okay" to "you should give this distribution a try".

The ClockworkPi GameShell is a super fun DIY spin on portable gaming

Gaming

Portable consoles are hardly new, and thanks to the Switch, they’re basically the most popular gaming devices in the world. But ClockworkPi’s GameShell is something totally unique, and entirely refreshing when it comes to gaming on the go. This clever DIY console kit provides everything you need to assemble your own pocket gaming machine at home, running Linux-based open-source software and using an open-source hardware design that welcomes future customization.

The GameShell is the result of a successful Kickstarter campaign, which began shipping to its backers last year and is now available to buy either direct from the company or from Amazon. The $159.99 ( on sale for $139.99 as of this writing) includes everything you need to build the console, like the ClockworkPi quad-core Cortex A7 motherboard with integrated Wi-Fi, Bluetooth and 1GB of DDR3 RAM — but it comes unassembled.

7 of the Best Linux Distros for Developers and Programmers

Development
GNU
Linux

One of the reasons Linux is great is because of how flexible it is. For example, it can run on everything from servers to your old laptop to a Raspberry Pi. For this reason, it’s also a fantastic platform for developers.

Whether you’re a seasoned developer or just using Linux to learn to program, you still have to choose a distribution. The reality is that you can pretty much be a developer with most Linux distros, but some have those little conveniences that make them head-and-shoulders above the crowd.

Here are the best Linux distros for developers.

Security: Sphinx, Ransomware, Webmin, YubiKey

  • Exposed Sphinx Servers Are No Challenge for Hackers [Ed: That’s the same agency and the same troll site that initially promoted the lies and the FUD about VLC]

    A popular open-source text search server, Sphinx offers impressive performance for indexing and searching data in databases or just in files. It is cross-platform, available for Linux, Windows, macOS, Solaris, FreeBSD, and a few other operating systems. [...] CERT-Bund posted the warning on Twitter today alerting network operators and providers about the risk of running Sphinx servers with a default configuration that are open on the web. The organization highlights that Sphinx lacks any authentication mechanisms. Exposing it on the web gives an attacker the possibility "to read, modify or delete any data stored in the Sphinx database."

  • Ransomware Hits Texas Local Governments [iophk: Windows TCO]

    The attack was observed on the morning of August 16 and appears to have been launched by a single threat actor, the DIR announcement reads.

    The State Operations Center (SOC) was activated soon after the attack reports started to come in, and DIR says that all of the entities that were actually or potentially affected appear to have been identified and notified.

    A total of twenty-three entities have been confirmed as impacted so far, and the responders are working on bringing the affected systems back online.

  • Webmin Backdoored for Over a Year

    The security hole impacts Webmin 1.882 through 1.921, but most versions are not vulnerable in their default configuration as the affected feature is not enabled by default. Version 1.890 is affected in the default configuration. The issue has been addressed with the release of Webmin 1.930 and Usermin version 1.780.

  • The YubiKey 5Ci is the 'first' iOS-compatible security key

    Like other YubiKey options in the 5 series, the YubiKey 5Ci supports multiple authentication protocols, including IDO2/WebAuthn, FIDO U2F, OTP (one-time-password), PIV (Smart Card), and OpenPGP.
