  • TFW an obituary you wrote five years ago goes viral

    This is not a new phenomenon. Social media snap-posts have killed off celebrities hundreds of times before their actual deaths (to the point where some have required websites to constantly fact-check their mortality). Facebook is full of years-late "RIP" posts. The Internet may never forget, but the humans who use it have become increasingly absent-minded.

    It wasn't even just my story that went viral—a similar Guardian story also resurfaced, probably because of the same "memories" feature on Facebook or some other social media feature that dredges up old content. Still, there was something personally unsettling about having words I had written in tribute of "dmr"—a man whom I credited personally for making my early exposure to computing and its potential possible—suddenly resurface five years later.

    The first few times I spotted Twitter acting up, I thanked people for resurfacing the story after so much time. But reading the post again—partially to make sure I hadn't somehow written another tribute subconsciously from my perch at my dad's bedside—was affecting in ways I didn't expect. Maybe I got emotional because I was in a hospital room with my father, who was recovering from an other-than-routine knee replacement surgery, and I had spent the day before sitting in a surgical waiting room.

LXer: DIY spooky bottle labels using Inkscape and coffee grounds

Saturday 15th of October 2016 05:07:49 PM
This year for Halloween, we decided to construct a witch's workbench out on the front porch. A trip to the local op shop produced an attractive candlestick, mortar (no pestle), and a small collection of bottles. Witches are nothing if not tidy, so we figured that bottles found near a serious witch's workshop would surely be carefully labeled. After all, one wouldn't want to accidentally use an eye of a frog when the potion calls for an eye of newt, would one?read more

  • Google releases Open Source Report Card -- does the company deserve an A+?

    The future of computing is open source. While there is still room for closed source software, more and more companies are going the open route. Major players such as Microsoft, Apple, and Facebook are all contributing to the open source community. Google in particular is a huge proponent of open source. Heck, two of the company's operating systems -- Chrome OS and Android -- are Linux distributions.

    Today, the search giant announces the 'Open Source Report Card'. This is essentially a report that explains the details of its open source projects. Google is undoubtedly a major open source contributor, but the question is, what grade should the company get?

    "Today we're sharing our first Open Source Report Card, highlighting our most popular projects, sharing a few statistics and detailing some of the projects we've released in 2016. We've open sourced over 20 million lines of code to date and you can find a listing of some of our best known project releases on our website", says Josh Simmons, Open Source Programs Office.

  • My FOSS Journey and Why I am applying for a Toptal Scholarship

    When I graduated from my high school in India, our class had an almost 50-50 ratio of boys-to-girls. My graduating class in one of India’s premier engineering institutions had less than 10%. It was even more interesting to see that there were more than 20% girls enrolled in Bachelors in Design (which offered courses like Product Design, Human Computer Interaction and User Experience Research) while there were none in Mechanical Engineering since the last three graduating classes. Was it that Design was considered a relatively non-technical course ? While I have never been openly discouraged from pursuing a career in technology – a predominantly male-populated field – there has always been an unconscious bias even from within my family. When I wanted to apply for a degree course in Mechanical Engineering, I was asked to take some more time to think about my future – was gently nudged towards more female-friendly engineering fields like Computer Science which wouldn’t involve as much strenuous physical effort. Was it even sublte experiences like this which had contributed towards the gender gap ? This feeling of being an ‘outsider’ in a predominantly male field never left till I started contributing to Open Source.

    I first learnt about Free and Open Source Software (FOSS) via Outreachy, a program designed to increase participation of minorities in FOSS. I liked the fact that the program had no knowledge prerequisites so that anyone interested in contributing to FOSS could be a part of it.

  • Microsoft open-sources P language for IoT
  • The White House open sources President Obama’s Facebook Messenger bot

    The White House today shared open source code for President Obama’s Facebook Messenger bot to help other governments build their own bots.

    The White House says it’s sharing the code “with the hope that other governments and developers can build similar services — and foster similar connections with their citizens — with significantly less upfront investment,” according to a post published today by chief digital officer for the White House Jason Goldman.

    In August, the White House launched a Facebook Messenger bot to receive messages from American citizens. The messages are read alongside letters and other communique sent to the president.

    The open source Drupal module for the president’s bot is available to download on Github.

    “While Drupal may not be the platform others would immediately consider for building a bot, this new White House module will allow non-developers to create bot interactions (with customized language and workflows), and empower other governments and agencies who already use Drupal to power their digital experiences,” Goldman said on the White House website today.

All jokes aside, this new Chromebook from Samsung actually looks really nice, and it can be picked up right now on Samsung Korea’s website.

  • Steam Finds Win 10 Losing Players, Win 7 and Linux Gaming Rising

    Does Linux hold a chance to compete with Windows as a gaming operating system? Well, not exactly. Despite Steam’s work on SteamOS, it doesn’t seem like Linux is about to become a major gaming operating system any time soon. But it’s definitely growing, and Steam users understand its benefits. Perhaps by this time next year, Mac will be going head-to-head with Linux players in the Steam Hardware Survey.

Is this a matter of the server being down and waiting for it to come back up, or is this a permanent issue?

Phoronix: Khronos, Mesa, Standards & Conformance / Certification: Open Source, Open Standards

Saturday 15th of October 2016 01:10:00 PM
The past week or two in our forums and elsewhere there's been a lot of comments about Khronos' conformance testing for OpenGL 4.4/4.5 with the Mesa drivers finally reaching that point, concern over Khronos' fees being prohibitive for open-source projects (particularly in cases like Nouveau where it's community driven without a main corporate backer), and some FUD related to this matter. I've now received some clarification from The Khronos Group to lay these concerns to rest...

Reddit: Searching for good resources regarding cloud architecture

Saturday 15th of October 2016 12:31:30 PM

I recently started a new job as an junior server admin in the cloud (~150 nodes with CentOS). I realised there is much to learn and I am willing. I was wondering maybe you guys can help me with some good resources (books, video, websites, etc..) that will enlighten my understanding. I think i have fair knowledge about individual components, but I fall short when pieces are connected together - architecture, (infrastructure?), topology, optimisation (the key term) and security.

The technology we use: load-balancing (haproxy), nginx, apache, MariaDB, Redis, Elastic-search, etc. All nodes are managed via salt (Salt Stack).

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.

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.
