Software
  • uGet 2.2.0 and uGet for Android 1.4.8 Now Available!

    After almost a year of development, we are excited to announce the immediate availability of the latest stable version of uGet, version 2.2.0 and the latest version of uGet for Android, version 1.4.8. These releases include a LOT of improvements such as bug fixes, maintenance improvements and many highly requested features like support for Downloading from YouTube.

  • 7 Best Open Source Linux Media Players You Need To Try In 2018

    Honestly speaking, I have started using media player software less often. That’s probably because of the online streaming boom in the last couple of years. It’s hard to remember the last time I slid a DVD into my computer. Most of the time, I find myself binge-watching TV shows on Prime Video (it even has a free trial in India), or some random stuff on YouTube.

  • Opera 51 Browser Enters Beta with Support for AppleScript and Many New Features

    The upcoming Opera 51 web browser was promoted on Thursday to the beta channel, giving users a more in-depth look at what to expect from the final release, which will be available next month.

Programming: Continuous Integration, JavaScript Frameworks, Visualizing Molecules with Python

  • Librsvg gets Continuous Integration

    One nice thing about gitlab.gnome.org is that we can now have Continuous Integration (CI) enabled for projects there. After every commit, the CI machinery can build the project, run the tests, and tell you if something goes wrong.

    Carlos Soriano posted a "tips of the week" mail to desktop-devel-list, and a link to how Nautilus implements CI in Gitlab. It turns out that it's reasonably easy to set up: you just create a .gitlab-ci.yml file in the toplevel of your project, and that has the configuration for what to run on every commit.

  • The Brutal Lifecycle of JavaScript Frameworks

    Using the Stack Overflow Trends tool and some of our internal traffic data, we decided to take a look at some of the more prominent UI frameworks: Angular, React, Vue.js, Backbone, Knockout, and Ember.
     

  • Visualizing Molecules with Python

    The PyMOL Wiki also hosts a script library, and it's a good place to look before you start down the road of creating your own script, as someone else may have run into the same issue and may have found a solution you can use. If nothing else, you may be able to find a script that could serve as a starting point for your own particular problem.

    When you're are done working with PyMOL, there are many different ways to end the session. If there is work you are likely to pick up again and continue with, click File→Save Session to save all of the work you just did, including all of the transitions applied to the view. If the changes you made were actually structural, rather than just superficial changes to the way the molecule looked, you can save those structural changes by selecting File→Save Molecule. This allows you to write out the new molecule to a chemical file format, such as a PDB file.

    If you need output for publications or presentations, a few different options are available. Clicking File→Save Image As allows you to select from saving a regular image file in PNG format or writing out data in a POVRay or VRML 3D file format. If you are doing a fancier presentation, you even can export a movie of your molecule by clicking File→Save Movie As. This lets you generate an MPEG movie file that can be used either on a web-based journal or within a slide deck for a presentation.

  • KPTI Support For 64-bit ARM Getting Buttoned Up Ahead Of Linux 4.16

    Kernel Page Table Isolation (KPTI) landed at the start of the year for x86/x86_64 systems for fending off the much talked about CPU attacks while the AMD64 / 64-bit ARM code is still a work-in-progress but looks like it will be squared away for the upcoming Linux 4.16 kernel cycle.

    There is this Git branch and the base work for those wishing to track the last minute alterations. There is currently the latest KPTI page table isolation patches for ARM64 and does include a return trampoline, a new HARDEN_BRANCH_PREDICTOR Kconfig switch, branch predictor hardening for Falkor and Cortex-A CPUs, and other security hardening improvements.

  • 'Very high level of confidence' Russia used Kaspersky software for devastating NSA leaks

    Three months after U.S. officials asserted that Russian intelligence used popular antivirus company Kaspersky to steal U.S. classified information, there are indications that the alleged espionage is related to a public campaign of highly damaging NSA leaks by a mysterious group called the Shadow Brokers.

    “That’s a Russian intelligence operation,” a former senior intelligence official, who requested anonymity to speak bluntly, told Yahoo Finance. “They’ve gotten a lot noisier than they used to be.”

Raspberry Pi Zero WH adds 40-pin GPIO header to Zero W

Filed under
Linux

The $18 Raspberry Pi Zero WH adds a soldered 40-pin GPIO header to the Zero W for easier prototyping or taking advantage of the new GPIO Expander tool, which lets you access your Pi’s GPIO pins from a PC running Debian Stretch.

Raspberry Pi Trading has launched a variation on the Raspberry Pi Zero W that makes it more like a regular Raspberry Pi SBC and less like a computer-on-module. Designed for those who would prefer not to solder, the new Raspberry Pi Zero W adds a “professionally soldered” 40-pin GPIO header, enabling easier prototyping or a better fit for temporary projects that need the Zero W’s small size and wireless radios, but don’t require the permanence of soldered connections.

MX Linux MX-17 Horizon - Shaping up beautifully

Filed under
Reviews

From an underdog to a kennel master. That's probably the best, most succinct way to describe MX Linux. While you still may be confused about its heritage, with words like Mepis and AntiX slipping in, it's one of the more refined Xfce distros around, and I have been thoroughly impressed by the last version, MX-16. As it turns out, I proudly crowned it the Best of Xfce 2017 distro. It also notched very high on the overall annual best-of competition.

Now, there's a new version out. I will first conduct the test on the old LG laptop, but now that I've managed to fix the read-only UEFI on my Lenovo G50 machine, I will conduct a second test on that laptop - provided everything works fine in this first review. So we have ancient hardware, Nvidia graphics, dual boot. Commence.

Tweaking Ubuntu 17.10 To Try To Run Like Clear Linux

Filed under
Ubuntu

Even with the overhead of having both KPTI and Retpoline kernel support in place, our recent Linux distribution benchmarks have shown Intel's Clear Linux generally outperforming the more popular distributions. But if applying some basic performance tweaks, can Ubuntu 17.10 perform like Clear Linux? Here are some benchmarks looking at a few factors.

In our forums there were recently some users attributing the Clear performance benefit to their CFLAGS and the distribution defaulting to the P-State "performance" governor rather than the "powersave" governor. It's true those are two of the ways this Intel open-source platform tries to deliver better out-of-the-box performance, but that is not all. Explained at ClearLinux.org, they also apply automatic feedback-driven optimizations (GCC FDO), function multi-versioning (FMV) to deliver optimized functions selected at run-time based upon the CPU micro-architecture being used, and various other approaches for trying to deliver the best out-of-the-box Linux performance that does include backporting various patches, etc. And, yes, hopefully this article can provide some motivation for Ubuntu and other distributions to become a bit more aggressive with their defaults to deliver a more optimized experience on installation.

  • News flash: encrypted.google.com is not special in any way

    Once upon a time, Google dared to experiment with HTTPS encryption for their search instead of allowing all search data to go unencrypted through the wire. For this experiment, they created a new subdomain: encrypted.google.com was the address where your could get some extra privacy. What some people apparently didn’t notice: the experiment was successful, and Google rolled out HTTPS encryption to all of their domains. I don’t know why encrypted.google.com is still around, but there doesn’t seem to be anything special about it any more. Which doesn’t stop some people from imagining that there is.

Hands on With System76’s Beautiful Linux Distro Pop!_OS

Filed under
GNU
Linux

When I saw that System 76 launched their #TryPopOS campaign last month I knew this was the perfect opportunity to really put Pop!_OS through its paces. I am a proud owner of the Galago Pro, which I purchased the day they launched pre-orders this Spring and it has been my primary computer since then. I use it for everything from writing articles, to browsing the internet, to light gaming, and though the machine as its quirks I am beyond happy with it.

Back when I ordered the laptop Pop!_OS wasn’t announced yet so my laptop came with stock Ubuntu, which I promptly replaced with Ubuntu GNOME. Since then I have tried a couple different options including Elementary OS, Manjaro GNOME Edition, and most recently I have settled on KDE Neon.

Everything I have thrown at it has worked great on it so far, but now it is time to try something different. Here is my experience with System 76’s Pop!_OS.

  • Meltdown and Spectre FAQ: Crapification at Scale

    Yesterday, Yves posted a “primers on Meltdown and Spectre”, which included several explanations of the two bugs from different viewpoints; if you feel you don’t have a handle on them, please review it. Today, I want to give an overview of the two bugs. I will dig into the details of these two bugs in the form of a FAQ, and then I’ll open a discussion of the larger business and political economy issues raised in the form of a MetaFAQ. First, I should make one point: Meltdown is a bug; Specture is a class of bugs (or, if you prefer, a strategy).

    [...]

    What Are The Costs of the Meltdown and Spectre Bugs?

    A few billions.

  • Fixing Chipmageddon Will Slow Down Older Computers

    Microsoft has come out and said it: cures for the pervasive chip flaws Meltdown and Spectre are likely to dent the performance of your PC if it’s a few years old.

  • Intel needs to come clean about Meltdown and Spectre

    Intel hasn’t had the best of times recently. Meltdown and Spectre security flaws have helped reveal fundamental issues with processor designs over the past 20 years, and the software updates to protect PCs will have performance impacts. Even as I write this, it’s still not clear to anyone exactly how bad these performance impacts will be for older desktop systems, or how significant they’ll be to server-based cloud platforms. It’s all a bit of a mess, and Intel hasn’t helped with its lack of transparency. It’s time for Intel to stop hiding behind cleverly worded statements.

  • Intel details performance hit for Meltdown fix on affected processors
  • Keeping Spectre secret

    When Graz University of Technology researcher Michael Schwarz first reached out to Intel, he thought he was about to ruin the company’s day. He had found a problem with their chips, together with his colleagues Daniel Gruss, Moritz Lipp, and Stefan Mangard. The vulnerability was both profound and immediately exploitable. His team finished the exploit on December 3rd, a Sunday afternoon. Realizing the gravity of what they’d found, they emailed Intel immediately.

    The security of mobile apps that tie in with Supervisory Control and Data Acquisition (SCADA) systems has deteriorated over the last two-and-a-half years, according to new research.

    A team of boffins from IOActive and IoT security startup Embedi said they had discovered 147 vulnerabilities in 34 of the most popular Android mobile apps for SCADA systems.

    Mobile applications are increasingly being used in conjunction with SCADA systems. The researchers warned these apps are "riddled with vulnerabilities that could have dire consequences on SCADA systems that operate industrial control systems".

My Linux story: Coding not required

For more than 15 years, I have earned a living working exclusively with open source products. How did I get here? In many ways, my journey started before Linux existed. In college, I had friends who were admins in the engineering computer lab. Although I did not do too well in my CS programming classes, as a hobby and to spend time with my friends I learned about newgroups, ftp sites, and Unix systems. As a data aide student intern, I realized I made a good translator between the astronomers and the C programmer computer support staff. I could read just enough code to identify the problem, but not enough to actually fix it. Read more
