Ubuntu
  • Best Linux Distribution

    This year we're breaking up our Readers' Choice Awards by category, so check back weekly for a new poll on the site. We started things off with Best Linux Distribution, and nearly 10,000 readers voted. The winner was Debian, with many commenting "As for servers, Debian is still the best" or similar.

    One to watch that is rising in the polls is Manjaro, which is independently based on the Arch Linux. Manjaro is a favorite for Linux newcomers and is known for its user-friendliness and accessibility.

  • Reproducible Builds: Weekly report #146
  • LXD weekly status #34
  • Ubuntu Server development summary – 13 February 2018

    The purpose of this communication is to provide a status update and highlights for any interesting subjects from the Ubuntu Server Team.

  • Ubuntu LoCo Council: Three month wrap-up

    The new LoCo Council has been a little lax with updating this blog. It’s admittedly taken us a little bit of time to figure out what exactly we’re doing, but we seem to be on our feet now. I’d like to rectify the blog issue by wrapping up the first three months of our reign in a summary post to get us back on track.

  • BH 1.66.0-1

    A new release of the BH package arrived on CRAN a little earlier: now at release 1.66.0-1. BH provides a sizeable portion of the Boost C++ libraries as a set of template headers for use by R, possibly with Rcpp as well as other packages.

    This release upgrades the version of Boost to the Boost 1.66.0 version released recently, and also adds one exciting new library: Boost compute which provides a C++ interface to multi-core CPU and GPGPU computing platforms based on OpenCL.

  • Data scientist wanted: Must have Python, spontaneity not required

    The average salary offered to data scientists in the past year was £47,000, with Python being the most desirable programming language, according to an analysis of job ads.

    The assessment, carried out by listings site Joblift, looked at 8,672 data scientist vacancies posted in the UK over the last 12 months.

    It found that data science salaries have increased at 3 per cent a month, which is a percentage point higher than the UK job market as a whole.

Open source: why is it such a big deal?

Filed under
OSS

What is open source software (OSS)? OSS is any program, application, operating system that is released along with its source code so that you, the user, can change it at will. Or at least have the option to utilise the services of a vendor of your choice. The fact that any other type of software exists is itself strange: would you buy a car that is completely sealed off from repair? No access to the engine, the tail-lights, or the windshield wiper? Even the tyres? One and only one company — the manufacturer of the car — will be able to fix even the smallest problem. Would you buy such a vehicle? Forget buying, given the current competition in vehicles, such a product would not last in the market for even a week.

The fact that people are selling you software that you cannot take to another person to fix, re-package, assist in providing even basic upgrades is in itself wrong and the discussion should end right here, IMHO. But that is a whole different topic and best left to camp-fire discussions; we have neither the will nor the wherewithal to turn an entire industry on its head.

  • Perfect Computer Security Is a Myth. But It’s Still Important [Ed: The "everything is broken" defeatism overlooks the coordinated vandalism done to put back doors in most things]

    Maybe you’ve heard it before: “Security is a myth.” It’s become a common refrain after a never-ending string of high-profile security breaches. If Fortune 500 companies with million dollar security budgets can’t lock things down, how can you?

    And there’s truth to this: perfect security is a myth. No matter what you do, no matter how careful you are, you will never be 100 percent safe from hackers, malware, and cybercrime. That’s the reality we all live in, and it’s important to keep this in mind, if only so that we can all feel more sympathy for victims.

  • Microsoft Fixes 50 Vulnerabilities In February’s Patch Tuesday Update

    Microsoft has released February’s cumulative updates for Windows 10, better known as Patch Tuesday. The reason why the update is worth getting is it comes with fixes for 50 vulnerabilities in various versions of Windows 10.

    As per the release notes, the software addressed as a part of the Patch Tuesday update are Windows OS, Microsoft Edge, Internet Explorer, Microsoft Office, Microsoft Office Services and Web Apps, and the JavaScript engine ChakraCore. In addition to security fixes, Microsoft has also made improvements to address minor glitches in Windows 10.

  • Telegram Zero-Day Vulnerability Lets Hackers Pwn Your PC to Mine Cryptocurrency

    A zero-day vulnerability was discovered by Kaspersky Lab in the Telegram Desktop app that could let hackers pwn your computer to mine for cryptocurrencies like Zcash, Monero, Fantomcoin, and others.

    Kaspersky Lab's security researchers say the zero-day vulnerability can be used to deliver multi-purpose malware to computer users using the Telegram Desktop app, including backdoors and crypto-cash mining software.

    The security company also discovered that hackers had actively exploited the vulnerability in the Telegram Desktop app, which is based on the right-to-left override Unicode method, since March last year, but only to mine cryptocurrencies like Fantomcoin, Monero, and Zcash.

    Atom 1.24 has been released on our stable channel and includes read-only TextEditors, asynchronous context menus, and automatic scrolling on folding and unfolding.

  • Atom Hackable Text Editor Gets Asynchronous Context Menus, Read-Only TextEditors

    GitHub updated today its open-source and cross-platform Atom hackable text editor app to add asynchronous context menus, read-only TextEditors, and automatic scrolling on unfolding and folding.

    Atom 1.24 is now available for Linux, Windows, and macOS, bringing asynchronous context menus to no longer lock up the even loop on right-click and allow other rendering and processing operations to occur when the context menu is displayed, a new LanguageMode API, automatic scrolling when folding or unfolding, and read-only TextEditors.

    "Packages can apply a read-only attribute to TextEditors to disable input," says Ash Wilson in the release notes. "This is useful when you wish to display code with syntax highlighting and allow copying to the clipboard, but it doesn’t make sense for the user to be able to change it, for example because it’s code in your git history or it isn’t on your local drive."

Five noteworthy open source projects

Filed under
OSS

The open-source movement has gained momentum over the last few years. So much so that The Linux Foundation recently formed the LF Networking Fund (LFN) in an effort to place multiple open source networking projects under a single umbrella. These types of projects allow virtually anyone to make modifications, and potentially improve, software code through a process called upstreaming. Given the numerous open source projects available, however, choosing one to contribute to can feel overwhelming. To simplify matters, the following — though far from an exhaustive list — highlights some noteworthy open source projects.

  • Rise of the Tomb Raider Is Coming to Linux and Mac, Ported by Feral Interactive

    Feral Interactive announced today that it started ported the Rise of the Tomb Raider dramatic action-adventure game featuring the gorgeous Lara Croft for the macOS and Linux platforms.

    Initially released in early November 2015 for Microsoft's Xbox 360 and Xbox One gaming consoles, and a year later for Sony's PlayStation 4 console, Rise of the Tomb Raider was available for the PC master race only on the Microsoft Windows operating system since January 2016.

    Using the latest Vulkan (on Linux) and Metal 2 API (on macOS) graphics technologies, the superb and thrilling Rise of the Tomb Raider adventure game is currently being ported by Feral Interactive, an UK-based video games publisher known for porting Tomb Raider 2013, to Mac and Linux platforms.

  • Farming sim 'Cattle and Crops' hits Steam Early Access, has Linux support

    If you're after a slightly more realistic farming sim, as in one that's not 2D pixel stuff, Cattle and Crops [Steam, Official Site] certainly seems interesting.

    Correct me if I'm wrong, I did look, but this might be the first "proper" farming sim to be made available on Linux. I didn't find anything else like it, so that's progress I guess. Earlier today, the game released on Steam and it's currently still in-development, so it's an Early Access title. The good news, is that Linux support is already there and it works reasonably well.

  • THQ Nordic now own Koch Media GmbH

    Not that it really means all that much for us, but interesting nonetheless, THQ Nordic has acquired Koch Media GmbH.

    Naturally, the announcements contain a lot of legal-speak, but some of it is quite interesting. THQ Nordic have actually put out a few Linux games like the revamp of Sphinx and the Cursed Mummy, the updated Imperium Galactica II and the RPG Silver. They're also the publisher of games that support Linux like The Book of Unwritten Tales, This Is the Police, The Dwarves and a bunch more.

  • The Linux beta of EVERSPACE has been updated with Unreal Engine 4.17 and bug fixes

    The unofficial Linux beta of space shooter EVERSPACE [Steam] has been updated again, this time it brings in an updated Unreal Engine 4.17 and bug fixes.

  • WHAT THE GOLF? A silly physics-based anti-golf game will support Linux

    What do you get when you attempt to turn everything into Golf? Silly physics-based anti-golf game WHAT THE GOLF? [Official Site, Fig Campaign] aims to answer that question. It's a game aimed at people who might find normal Golf a bit boring, like me.

    It's being developed by developer Triband, who are also working on "Keyboard Sports - Saving QWERTY" [Steam] which will also have Linux support that will release sometime this year.

  • Have you played HyperRogue? A non-Euclidean roguelike that combines a free and paid model

    HyperRogue [Official Site, Steam, itch.io] is a non-Euclidean roguelike that has not only messed with my brain, it also combines a free and paid development model with code that's under the GPL.

  • Fantasy Farming: Orange Season, a farm-life RPG recently added Linux support

    While searching for other farming sims while covering Cattle and Crops, I ended up coming across Fantasy Farming: Orange Season [Steam, Official Site, itch.io] and it just recently added Linux support. It's being developed by Hudell Tales, which is made up on a single developer.

    Note: It's currently in Early Access so it's not finished—expect bugs.

  • Inductive Bias: FOSDEM 2018 - recap

    Too crowded, too many queues, too little space - but also lots of friendly people, Belgian waffles, ice cream, an ASF dinner with grey beards and new people, a busy ASF booth, bumping into friends every few steps, meeting humans you see only online for an entire year or more: For me, that's the gist of this year's FOSDEM.

    Note: German version of the article including images appeared in my employer's tech blog.

    To my knowledge FOSDEM is the biggest gathering of free software people in Europe at least. It's free of charge, kindly hosted by ULB, organised by a large group of volunteers. Every year early February the FOSS community meets for two one weekend in Brussels to discuss all sorts of aspects of Free and Open Source Software Development - including community, legal, business and policy aspects. The event features more than 600 talks as well as several dozen booths by FOSS projects and FOSS friendly companies. There's several FOSDEM fringe events surrounding the event that are not located on campus. If you go to any random bar or restaurant in Brussels that weekend you are bound to bump into FOSDEM people.

Emtrion’s Linux-friendly “emCON-RZ/G1H” module features an octa-core Renesas RZ/G1H SoC, up to 32GB eMMC, dual CAN interfaces, and extended temperature support, and is available with a carrier board.

Like iWave’s Qseven form factor iW-RainboW-G21M-Q7 computer-on-module, Emtrion’s emCON-RZ/G1H taps the Renesas RZ/G1H SoC (model R8A7742), which combines 4x 1.4GHz Cortex-A15 cores, 4x 780MHz Cortex-A7 cores and a 3D-ready Imagination Technologies PowerVR G6400 GPU clocked at 520MHz. Emtrion usually works with NXP or TI SoCs, and in the past has dabbled in Atmel, as in its circa-2014, ATSAMA5D36 based SBC-SAMA5D36.

Security: Telegram, Bounties and More

  • Telegram zero-day let hackers spread backdoor and cryptocurrency-mining malware

    A zero-day vulnerability in Telegram Messenger allowed attackers to spread a new form of malware with abilities ranging from creating a backdoor trojan to mining cryptocurrency.

    The attacks take advantage of a previously unknown vulnerability in the Telegram Desktop app for Windows and were spotted being used in the wild by Kaspersky Lab.

    Researchers believe the Russian cybercriminal group exploiting the zero-day were the only ones aware of the vulnerability and have been using it to distribute malware since March 2017 -- although it's unknown how long the vulnerability had existed before that date.

  • More Than 4,000 Government Websites Infected With Covert Cryptocurrency Miner

    The rise of cryptocurrency mining software like Coinhive has been a decidedly double-edged sword. While many websites have begun exploring cryptocurrency mining as a way to generate some additional revenue, several have run into problems if they fail to warn visitors that their CPU cycles are being co-opted in such a fashion. That has resulted in numerous websites like The Pirate Bay being forced to back away from the software after poor implementation (and zero transparency) resulted in frustrated users who say the software gobbled upwards of 85% of their available CPU processing power without their knowledge or consent.

    But websites that don't inform users this mining is happening are just one part of an emerging problem. Hackers have also taken to using malware to embed the mining software into websites whose owners aren't aware that their sites have been hijacked to make somebody else an extra buck. Politifact was one of several websites that recently had to admit its website was compromised with cryptocurrency-mining malware without their knowledge. Showtime was also forced to acknowledge (barely) that websites on two different Showtime domains had been compromised and infected with Coinhive-embedded malware.

  • Why Bug Bounties Matter

    Bugs exist in software. That's a fact, not a controversial statement. The challenge (and controversy) lies in how different organizations find the bugs in their software.

    One way for organizations to find bugs is with a bug bounty program. Bug bounties are not a panacea or cure-all for finding and eliminating software flaws, but they can play an important role.

  • Shell Scripting and Security

    The internet ain't what it used to be back in the old days. I remember being online back when it was known as ARPAnet actually—back when it was just universities and a handful of corporations interconnected. Bad guys sneaking onto your computer? We were living in blissful ignorance then.

    Today the online world is quite a bit different, and a quick glimpse at the news demonstrates that it's not just global, but that bad actors, as they say in security circles, are online and have access to your system too. The idea that any device that's online is vulnerable is more true now than at any previous time in computing history.

It's been a while since last having anything to report on Devuan, the Debian derivative focused on "init freedom" by shipping the Debian packages without any dependence on systemd. But just in time for Valentine's Day, Devuan 2.0 Beta is now available.

Devuan 1.0 was released last year and based on the Debian Jessie package set while the Devuan 2.0 development is tracking Debian Stretch. Thus with the switch to Devuan 2.0 comes a lot of upstream package updates while this distribution remains committed to shipping without systemd and still providing a GNU/Linux desktop experience.

    A year and a couple of months ago, Christian Schaller asked me to pivot a little bit from working full time on Fleet Commander to manage a new team we were building to work on client hardware enablement for Fedora and GNOME with an emphasis on upstream. The idea was to fill the gap in the organization where nobody really owned the problem of bringing up new client hardware features vertically across the stack (from shell down to the kernel), or rather, ensure Fedora and GNOME both work great on modern laptops. Part of that deal was to take over the bootloader and start working closer to customers and hardware manufacturing parnters.

    The glxinfo utility is handy for Linux users in checking on their OpenGL driver in use by their system and related information. But it's not often that glxinfo itself gets updated, except that changed today with the release of mesa-demos-8.4.0 as the package providing this information utility. Mesa-demos is the collection of glxinfo, eglinfo, glxgears, and utilities related to Mesa. With the Mesa-demos 8.4.0 it is predominantly glxinfo updates.

The patches are here for those interested in 16-bit storage support in Vulkan. This flips on the features for storageBuffer16BitAccess, uniformAndStorageBuffer16BitAccess, storagePushConstant16 and the VK_KHR_16bit_storage extension. This support is present for Intel "Gen 8" Broadwell graphics and newer. Hopefully the work will be landing in Mesa Git soon.
