  • ​Javascript Tool Maker Relents After Mixing Immigration Politics with Open Source Licensing

    In very short order, Lerna, a company that offers some Javascript tooling, has learned the hard way not to mess with the integrity of an open source license. In other words, don’t decide you’re going to take an existing OSI-certified open source license, modify it to suit your agenda, license your code under the newly derived license, and still continue to refer to your offering as "open source.”

    First, this analysis piece is really just a follow up to my previous post about why it’s time to reject the latest attack on open source software (OSS). The main point of that post was to point out that all of us who have experienced the benefits of open source (ok, that’s nearly all human beings) should play a role in defending it. Otherwise, it will whither and so too will the benefits most of us have come to enjoy, blind to the fact that open source is playing such an important role in our lives.

  • gPodder – podcast client written in Python

    gPodder is an open source tool that downloads and manages free audio and video content (“podcasts”) for you. The software is written in Python and sports a simple GTK interface. The software package also includes a command-line interface which is called gpo. It lets you listen to podcasts on your computer or on mobile devices. The software is very mature; it’s been in development since 2005.

  • FOSS Project Spotlight: Run Remote Tasks on Linux and Windows with Puppet Bolt

    Puppet, the company that makes automation software for managing systems and delivering software, has introduced Puppet Bolt, an open-source, agentless multiplatform tool for running commands, scripts, tasks and orchestrated workflows on remote Linux and Windows systems.

    The tool, which is freely available as a Linux package, Ruby gem and macOS or Windows installer, is ideal for sysadmins and others who want to perform a wide range of automation tasks on remote bare-metal servers, VMs or cloud instances without the need for any prerequisites. Puppet Bolt doesn't require any previous Puppet know-how. Nor does it require a Puppet agent or Puppet master. It uses only SSH and WinRM (or can piggyback Puppet transports) to communicate and execute tasks on remote nodes.

    Despite its simplicity, Puppet Bolt can execute all your existing scripts written in Bash, PowerShell, Python or any other language, stop and start Linux or Windows services, gather information about packages and system facts, or deploy procedural orchestrated workflows, otherwise known as plans. You can do all this right from your workstation or laptop.

  • Amazon Alexa Security Risk Allows Hackers to Take Over Voice Commands, Steal Private Information

    The world is changing and in the modern era, we are becoming reliant on our Internet of Things devices by the day. But this reliances could cost us everything, it could allow someone to steal our identity, bank information, medical history, and what not.

    Amazon Alexa has been criticised for having a number of security flaws but Amazon has been quick to deal with them. However, this new security flaw may not have a fix at all. And this could be the most dangerous security threat yet.

    According to research conducted by the University of Illinois at Urbana-Champaign (UIUC), Amazon Alexa’s idiosyncrasies can be exploited through voice-commands to route users to malicious websites. Hackers are targeting the loopholes in machine learning algorithms to access private information.

  • Researchers show Alexa “skill squatting” could hijack voice commands

    The success of Internet of Things devices such as Amazon's Echo and Google Home have created an opportunity for developers to build voice-activated applications that connect ever deeper—into customers' homes and personal lives. And—according to research by a team from the University of Illinois at Urbana-Champaign (UIUC)—the potential to exploit some of the idiosyncrasies of voice-recognition machine-learning systems for malicious purposes has grown as well.

    Called "skill squatting," the attack method (described in a paper presented at USENIX Security Symposium in Baltimore this month) is currently limited to the Amazon Alexa platform—but it reveals a weakness that other voice platforms will have to resolve as they widen support for third-party applications. Ars met with the UIUC team (which is comprised of Deepak Kumar, Riccardo Paccagnella, Paul Murley, Eric Hennenfent, Joshua Mason, Assistant Professor Adam Bates, and Professor Michael Bailey) at USENIX Security. We talked about their research and the potential for other threats posed by voice-based input to information systems.

  • The Linux Foundation Set to Improve Open-Source Code Security

    CII is now working on further trying to identify which projects matter to the security of the internet as a whole, rather than taking a broader approach of looking at every single open-source project, he said. In his view, by prioritizing the projects that are the most critical to the operation of the internet and modern IT infrastructure, the CII can be more effective in improving security.

    "You'll see in the next three months or so, additional activity coming out of CII," Zemlin said.

    Among the new activities coming from the CII, will be additional human resources as well as new funding. The Linux Foundation had raised $5.8 million from contributors to help fund CII efforts, which Zemlin said has now all been spent. Zemlin that CII's money was used to fund development work for OpenSSL, NTP (Network Time Protocol) and conducting audits.

  • Apache Struts 2.3.25 and 2.5.17 resolve Cryptojacking Exploit Vulnerability

    Information regarding a severe vulnerability found in Apache Struts was revealed last week. A proof of concept of the vulnerability was also published publicly along with the vulnerability’s details. Since then, it seems that malicious attackers have set out to repeatedly exploit the vulnerability to remotely install a cryptocurrency mining software on users’ devices and steal cryptocurrency through the exploit. The vulnerability has been allotted the CVE identification label CVE-2018-11776.

    This behavior was first spotted by the security and data protection IT company, Volexity, and since its discovery, the rate of exploits has been increasing rapidly, drawing attention to the critical severity of the Apache Struts vulnerability. The company released the following statement on the issue: “Volexity has observed at least one threat actor attempting to exploit CVE-2018-11776 en masse in order to install the CNRig cryptocurrency miner. The initial observed scanning originated from the Russian and French IP addresses 95.161.225.94 and 167.114.171.27.”

Gnome 3 & best extensions

Filed under
GNOME

There you go. Writing this article got me thinking. Gnome 3 is like Firefox 57. It brought about a radical change, made a lot of what made the original version great redundant, and hid options from users, making customization difficult. Gnome 3 also fights hard against extensions. But these are the bread and butter of what makes it useful, practical and appealing to users. The same is also true of Cinnamon, which has also partially been afflicted the same way. Technically, one may claim that extensions are a poor excuse for bad design, but then, in general, history has shown that they do make products more engaging in the long run. Collective intelligence can be a good thing, especially when harvested for free.

I am still convinced that Gnome 3 is doing it wrong, and that Plasma, Unity or even MATE are much better solutions on all levels. But then, if you do want to use this desktop environment, there are several handy extensions that can truly transform the experience. The must-have set, and then a sweetening of five nice little extras, which help make the desktop more useful and fun. If you have any other suggestions, this is a good time to use your email sending skills. And we're done.

BSD

Last week I posted some initial tests and benchmarks of DragonFlyBSD/FreeBSD on the AMD Threadripper 2990WX. While that went well and the BSDs scale with this 32-core / 64-thread processor better than Windows, lead DragonFly developer Matthew Dillon had picked up a 2990WX system and has been tuning the kernel ever since. Here are some benchmarks looking at some of his recent optimizations.

Hours after that BSD Threadripper testing ended last week, Matthew Dillon landed some more performance tuning/optimizations to benefit the Threadripper 2990WX design. Here are some benchmarks of that original 2990WX support on DragonFlyBSD 5.3-DEVELOPMENT compared to the later daily snapshot.

SharkLinux Distro: Open Source in Action

Filed under

OSS

Every so often I run into a Linux distribution that reminds me of the power of open source software. SharkLinux is one such distribution. With a single developer creating this project, it attempts to change things up a bit. Some of those changes will be gladly welcomed by new users, while scoffed at by the Linux faithful. In the end, however, thanks to open source software, the developer of SharkLinux has created a distribution exactly how he would want it to be. And that my friends, is one amazing aspect of open source. We get to do it our way.

But what is SharkLinux and what makes it stand out? I could make one statement about SharkLinux and end this now. The developer of SharkLinux reportedly developed the entire distribution using only an Android phone. That, alone, should have you wanting to give SharkLinux a go.

  • What you need to know about automation testing in CI/CD

    Test automation means focusing continuously on detecting defects, errors, and bugs as early and quickly as possible in the software development process. This is done using tools that pursue quality as the highest value and are put in place to ensure quality—not just pursue it. One of the most compelling features of a continuous integration/continuous delivery (CI/CD) solution (also called a DevOps pipeline) is the opportunity to test more frequently without burdening developers or operators with more manual work. Let's talk about why that's important.

  • Generics for Go

    The Go programming language was first released in 2009, with its 1.0 release made in March 2012. Even before the 1.0 release, some developers criticized the language as being too simplistic, partly due to its lack of user-defined generic types and functions parameterized by type. Despite this omission, Go is widely used, with an estimated 1-2 million developers worldwide. Over the years there have been several proposals to add some form of generics to the language, but the recent proposal written by core developers Ian Lance Taylor and Robert Griesemer looks likely to be included in a future version of Go. [...] Generics, also known as "parameterized types" or "parametric polymorphism", are a way to write code or build data structures that will work for any data type; the code or data structure can be instantiated to process each different data type, without having to duplicate code. They're useful when writing generalized algorithms like sorting and searching, as well as type-independent data structures like trees, thread-safe maps, and so on. For example, a developer might write a generic min() function that works on all integer and floating-point types, or create a binary tree that can associate a key type to a value type (and work with strings, integers, or user-defined types). With generics, you can write this kind of code without any duplication, and the compiler will still statically check the types.

  • Fixing a common antipattern when loading translations in Qt

    I’m a Polish guy working with computers, mostly on Windows. However, the lingua franca of the IT industry is English, so every time I see a tutorial for some dev tool, it’s in that language. To lessen the burden of decoding which menu entry in the tutorial corresponds to which menu entry on my PC I decided to run the system with an English display language. I still want the rest of the i18n-related stuff (date format, keyboard, currency etc.) to be in Polish however. [...] As you can see, Thunderbird and Windows Settings show up in English but Qt Linguist is encrypted with some overengineered Slavic cipher (aka Polish language). What I further noticed, is that this incorrect language selection is particularly prevalent in Qt-based applications. Subsequent digging revealed that this antipattern is widespread in Qt world, see the relevant GitHub search (requires login).

  • Android 10 has the fastest update rate ever, hits 16% of users in 10 months

    Google today dropped a blog post detailing its progress on improving the Android ecosystem's update speed. The company has been hard at work for the past few years modularizing Android, with the hope that making Android easier to update would result in device manufacturers pushing out updates faster. Google's efforts have been paying off, with the company announcing Android 10 has had the fastest rollout ever. The last few versions of Android have each brought a major improvement to Android's update system. Android 8 introduced Project Treble, which separated the OS from the hardware support, enabling easier porting of Android across devices. In Android 9 Pie, Google completed its work on Treble and started publishing Generic System Images (GSIs): drop-in versions of Android that work on any Project Treble-compatible device. Android 10 introduced Project Mainline and the new APEX file type designed for updatable lower-level system components, delivered through the Play Store. Google's stats show that all this work is actually improving the ecosystem. "Thanks to these efforts," Google writes, "the adoption of Android 10 has been faster than any previous versions of Android. Android 10 was running on 100 million devices 5 months post launch—28% faster than Android Pie."
