TuxMachines: Development News

Saturday 8th of October 2016 11:05:53 AM
  • GDB 7.12 released!

    Release 7.12 of GDB, the GNU Debugger, is now available via anonymous FTP. GDB is a source-level debugger for Ada, C, C++, Objective-C, Pascal and many other languages. GDB can target (i.e., debug programs running on) more than a dozen different processor architectures, and GDB itself can run on most popular GNU/Linux, Unix and Microsoft Windows variants.

  • GDB 7.12 Released With Rust Debugging, Python Enhancements

    GDB 7.12 is now available as the latest feature release of the GNU Debugger.

    Arguably most exciting about GDB 7.12 is that it now supports debugging programs written in Rust! But if Rust support doesn't excite you, there is also some Fortran support improvements and various Python language enhancements.

  • Should Math be a Prerequisite for Programming?

    In her LinuxCon Europe talk, “The Set of Programmers: How Math Restricts Us,” Carol Smith, Education Partnership Manager at GitHub, got us thinking about how math requirements impact our ability to bring more people into the field of computer programming.

    Carol kicked off her talk with a story about how she traveled to New Zealand with two friends, Boris and Natasha (not their real names), and learned that Boris has agoraphobia, which causes him extreme anxiety in open spaces. New Zealand, as it turns out, is full of wide open spaces. During one hike, Boris really struggled with crossing the long bridge across a gully. The more he told himself he could do it, the harder it was. He felt like he should be able to do this and felt like he was the only person who couldn't do it. A lot of people get this feeling when they try to do math. They feel like everyone else can do math, and the more they think this, the more they feel like they are the only person who can't do math.

  • Rust and Automake

    Yes it is. But it is also limited to build the Rust crate. It does one thing, very well, and easily.

    Although I'm writing a GNOME application and this needs more than building the code. So I decided I need to wrap the build process into automake.

    Let's start with Autoconf for Rust Project. This post is a great introduction to solving the problem and give an actual example on doing it even though the author just uses autoconf. I need automake too, but this is a good start.

TuxMachines: SUSE Leftovers

  • Dominique Leuenberger: openSUSE Tumbleweed – Review of the Week 2016/40
  • ERR_NETWORK_CHANGED in Chrome/Chomium @openSUSE_Tumbeweed @DELL_5510
  • YaST Team: Improving low-vision accessibility of the installer

    In our latest report, we promised you would not have to wait another three weeks to hear (or read) from us. And here we are again, but not with any of the anticipated topics (build time reduction and Euruko 2016), but with a call for help in a topic that could really make a difference for (open)SUSE.

    Nowadays, YaST team is trying to fix a long-standing issue in the installer: low-vision accessibility. In the past, a user could get a high-contrast mode just pressing shift+F4 during installation. Unfortunately, that feature does not work anymore and, to be honest, changing to a high-contrast palette is not enough. Other adjustments, like setting better font sizes, should be taken into account.

    Another option is to use the textmode installation and set some obscure variable (Y2NCURSES_COLOR_THEME) to get the high-contrast mode. But it sounds like the opposite to user friendly.

TuxMachines: 6 Ways Mr. Robot Is Putting Linux in the Public Eye

Saturday 8th of October 2016 10:22:50 AM

One of the main Linux draws is its customization, and one of the most important areas is the desktop environment. Of the Linux desktop environments, GNOME and KDE are two of the leading environments. Tyrell Wellick (Martin Wallström) says to protagonist Elliot, “So I see you’re running Gnome! You know I’m actually on KDE myself.” Those familiar with Linux and its environments will appreciate this moment, especially Wellick’s follow up, “Yeah, I know what you’re thinking, I’m an executive running Linux, why am I even running Linux?”

Not only do we learn about KDE and GNOME, but there’s even a bit about the perception of Linux use in the enterprise (hint: it’s usually relegated to sysadmins and tech specialists, not execs).

TuxMachines: Security News

Saturday 8th of October 2016 10:19:47 AM
  • Security advisories for Friday
  • surveillance, whistleblowing, and security engineering

    Imagine for a moment that you are a security engineer who discovers a backdoor that your company execs have been trying to hide from your team. Would you quit on ethical grounds or stay so that you can prevent this from happening again? I don’t think there is one right answer. Personally I am grateful both for those who left and blew the whistle, and for those who stayed to protect Yahoo’s 800 million users.

    Part of the job function of security engineers and pen testers is being ready for the moment you encounter something that you think should be disclosed but your company wants to keep secret. Think about what you would be willing to lose. Be prepared to escalate internally. Know the terms of your NDA and your exit agreement; try your best to honor them. Most of all, keep pushing for end-to-end encryption.

  • Digital Vigilantes Want to Shame DDoS Attackers And Their Corporate Enablers

    Hacker attacks that try to take down websites with a flood of bogus traffic, technically known as Distributed Denial of Service (DDoS) attacks, have become a daily occurrence on the internet. The rise of DDoS has created a cottage industry of companies dedicated to mitigating the attacks, and, on the flip side, professional DDoS-for-hire services and gangs.

    Now, a group of security researchers wants to name and shame not only the hackers responsible for such crippling attacks, but also the internet providers and traffic carriers that enable them by turning a blind eye to their actions, with a project called SpoofIT.

  • Russia Drafting Law to Favor Open Source

    I wrote the original cyber-vulnerability letter to the White House in 1994, and instead of acting responsibly, the US Government allowed NSA -- with the active complicty of US communicaitons and computing provider CEOs -- to compromise all US offerings. Not only are the communications and computing devices and related consulting compromised, but so are larger offerings (e.g. Boeing aircraft, which come with a computer system pre-configured for US Government remote control take-over -- Lufthansa is reported to have discovered this and at great expense removed all US computers from every aircraft). NOTE: I am quite certain about both of the above indictments, but only a proper European Commission investigation can satisfy the public interest; I believe that the same problems infect C4I systems from China, France, Israel, and Russia, and I do not believe most people are aware that the electrical system is now easily used to enter computers that are nominally disconnected from the Internet.

  • Systemd vulnerability crashes Linux systems

    A new vulnerability has been discovered that could shut down most Linux systems using a command short enough to fit in a tweet.

Reddit: Learning Linux for the more tech savvy

Saturday 8th of October 2016 08:39:57 AM

Hey, Reddit!

First, I'm going to start with some background info about myself. When I was younger, I spent a lot of time on RH, Mandrake, and the occasional backtrack when I felt like experimenting. I took a few classes in school about networking, flashing Cisco routers, and running Linux servers, but even more time learning things on my own - mostly digging deeper into things I was currently learning in class that I knew the class wouldn't teach me. Long story short, I'm the type of person who loves learning the more in-depth details of how and why things work and the rules set forth by current protocols so that I can better bend or sometimes break them to accomplish what I want done.

Now... Fast forward a number of years. I haven't touched Linux in probably 8 or 9 years. I just began going to college for I.T./CS after spending a number of years away doing unrelated work. I still know many of the basics (cd, ls, grep, more/less, editors (vi, vim, etc), blah blah blah) but as for learning more, I don't even know where to begin. Every beginner book I pick up, I get bored with easily because I already know 90+ percent of the content, yet every more advanced book I pick up, I'm completely lost because I don't understand the mid-level protocols that it's assumed I know.

So where can I learn? How do I begin learning if I don't know what to specifically research? Are there any resources out that are set up similarly to the way CodeAcademy is for programming where it's very easy to get through basics to get to the relevant content? I guess I'm just having trouble knowing what to look for...

Thanks so much for your time.

TL;DR - Out of the tech game for a while, need advice on where to relearn things that are neither too basic nor too difficult. Resources similar to CodeAcademy?

TuxMachines: i.MX8 “eCockpit” SoC arrives, with media and IoT versions coming

Saturday 8th of October 2016 07:48:09 AM

NXP unveiled its automotive i.MX8 Quad with four Cortex-A53 cores, two Cortex-M4F cores, and two GPUs. The QuadPlus and QuadMax add one and two -A72 cores.

Freescale teased its automotive i.MX8 family in 2015 before the company was acquired by NXP, a process that may have contributed to the SoC family’s delays. The first three i.MX8 models are now due to sample in Q1 2017, says NXP, which has already built a development kit for the SoC, shown farther below. In addition, plans have leaked for future i.MX8 models for multimedia and low-power IoT applications, including dual-core models (see farther below).

TuxMachines: LeEco Accidentally Reveals Phone, Android TV Lineup Ahead of U.S. Launch

Saturday 8th of October 2016 07:41:21 AM

Chinese hardware upstart LeEco accidentally showed off key parts of its device lineup two weeks before the company is set to officially launch its US business Friday. The leak, which was first spotted by AndroidPolice, revealed two budget-phones as well as four different TV sets based on Google’s Android TV platform.

Product shots also show numerous LeEco-branded apps, suggesting that the company wants to use its devices to grow its entertainment services, much like it has done in China. A LeEco spokesperson didn’t immediately respond to a request for comment.

Games for GNU/Linux

  • Why GNU/Linux ports can be less performant, a more in-depth answer
    When it comes to data handling, or rather data manipulation, different APIs can perform it in different ways. In one, you might simply be able to modify some memory and all is ok. In another, you might have to point to a copy and say "use that when you can instead and free the original then". This is not a one way is better than the other discussion - it's important only that they require different methods of handling it. Actually, OpenGL can have a lot of different methods, and knowing the "best" way for a particular scenario takes some experience to get right. When dealing with porting a game across though, there may not be a lot of options: the engine does things a certain way, so that way has to be faked if there's no exact translation. Guess what? That can affect OpenGL state, and require re-validation of an entire rendering pipeline, stalling command submission to the GPU, a.k.a less performance than the original game. It's again not really feasible to rip apart an entire game engine and redesign it just for that: take the performance hit and carry on. Note that some decisions are based around _porting_ a game. If one could design from the ground up with OpenGL, then OpenGL would likely give better performance...but it might also be more difficult to develop and test for. So there's a bit of a trade-off there, and most developers are probably going to be concerned with getting it running on Windows first, GNU/Linux second. This includes engine developers.
  • Why Linux games often perform worse than on Windows
    Drivers on Windows are tweaked rather often for specific games. You often see a "Game Ready" (or whatever term they use now) driver from Nvidia and AMD where they often state "increased performance in x game by x%". This happens for most major game releases on Windows. Nvidia and AMD have teams of people to specifically tweak the drivers for games on Windows. Looking at Nvidia specifically, in the last three months they have released six new drivers to improve performance in specific games.
  • Thoughts on 'Stellaris' with the 'Leviathans Story Pack' and latest patch, a better game that still needs work
  • Linux community has been sending their love to Feral Interactive & Aspyr Media
    This is awesome to see, people in the community have sent both Feral Interactive & Aspyr Media some little care packages full of treats. Since Aspyr Media have yet to bring us the new Civilization game, it looks like Linux users have been guilt-tripping the porters into speeding up, or just sending them into a sugar coma.
  • Feral Interactive's Linux ports may come with Vulkan sooner than we thought
  • Using Nvidia's NVENC with OBS Studio makes Linux game recording really great
    I had been meaning to try out Nvidia's NVENC for a while, but I never really bothered as I didn't think it would make such a drastic difference in recording gaming videos, but wow does it ever! I was trying to record a game recently and all other methods I tried made the game performance utterly dive, making it impossible to record it. So I asked for advice and eventually came to this way.

Leftovers: Software

  • DocKnot 1.00
    I'm a bit of a perfectionist about package documentation, and I'm also a huge fan of consistency. As I've slowly accumulated more open source software packages (alas, fewer new ones these days since I have less day-job time to work on them), I've developed a standard format for package documentation files, particularly the README in the package and the web pages I publish. I've iterated on these, tweaking them and messing with them, trying to incorporate all my accumulated wisdom about what information people need.
  • Shotwell moving along
    A new feature that was included is a contrast slider in the enhancement tool, moving on with integrating patches hanging around on Bugzilla for quite some time.
  • GObject and SVG
    GSVG is a project to provide a GObject API, using Vala. It has almost all, with some complementary, interfaces from W3C SVG 1.1 specification. GSVG is LGPL library. It will use GXml as XML engine. SVG 1.1 DOM interfaces relays on W3C DOM, then using GXml is a natural choice. SVG is XML and its DOM interfaces, requires to use Object’s properties and be able to add child DOM Elements; then, we need a new set of classes.
  • LibreOffice 5.1.6 Office Suite Released for Enterprise Deployments with 68 Fixes
    Today, October 27, 2016, we've been informed by The Document Foundation about the general availability of the sixth maintenance update to the LibreOffice 5.1 open-source and cross-platform office suite. You're reading that right, LibreOffice 5.1 got a new update not the current stable LibreOffice 5.2 branch, as The Document Foundation is known to maintain at least to versions of its popular office suite, one that is very well tested and can be used for enterprise deployments and another one that offers the latest technologies.
