Sci/Tech

In October 2014, Databricks participated in the Sort Benchmark and set a new world record for sorting 100 terabytes (TB) of data, or 1 trillion 100-byte records. The team used Apache Spark on 207 EC2 virtual machines and sorted 100 TB of data in 23 minutes.

In comparison, the previous world record set by Hadoop MapReduce used 2100 machines in a private data center and took 72 minutes. This entry tied with a UCSD research team building high performance systems and we jointly set a new world record.

Lightweight DBMS guides Linux-based cow feeding robot

Filed under
Linux
Sci/Tech

Ittia announced a design win for its lightweight embedded DB SQL database in Wasserbauer’s uClibc Linux based “Butler Gold” robot designed to feed cattle.

The Ittia DB SQL database and its antecedents, including .db*, have shipped in a wide variety of devices, including a circa 2005, Linux-based Oshkosh A3 HEMTT tactical truck. The lightweight, Linux- and Android-compatible embedded relational database has now found its way into barnyard life in its role within a Butler Gold cattle-feeding robot from Germany’s Wasserbauer GmbH. Linux has previously played a role in DeLaval’s Voluntary Milking System robot for cattle, but this is the first time we’ve seen it helping out on the other end.

Sci/Tech

It was a pretty long project. I didn’t work on it full time, obviously, but I probably worked on it over a period of six months, and most of the time was writing the software. A lot of the software was written in Python – like the controls for the webcam, the soundboard and everything – so most of the time was getting the software running and getting the kinks worked out. Like where if it loses a Wi-Fi connection it tries to rejoin and things like that. So, yeah, I definitely want to revisit it, and obviously the second time round you can do it a lot better than you did the first, so I’d like to go back.

Google investing $50 million to get girls to code

Sci/Tech
Misc

Google conducted research to determine why girls are opting out of learning how to code? As a result Google found that most girls decide before they even enter college whether they want to learn to code—so the Tech-world must win them over them at a young age. They also found that there were four major factors that determined whether girls opted into computer science: social encouragement, self-perception, academic exposure and career perception. According to recent studies less than 1 percent of high school girls express interest in majoring in computer science.

icons and Themes: Vamox , Ashes, and DamaDamas

  • Vamox Icons Offers Three Color Variants for Linux Desktop
    Vamox icons were designed as a university thesis project by Emiliano Luciani and Darío Badagnani in 2008. The objective was to design a interface of a distro that the university could use for learning about design thin free software, From start these icons were developed for Ubuntu. Now these icons has three variants blue, orange and red, which are compatible with most of the Linux desktop environments such as: Gnome, Unity, Cinnamon, Mate, Xfce and so on. We have added these icons to our PPA for Ubuntu/Linux Mint and other related distributions, If you are using distribution other than Ubuntu/Linux Mint/its derivatives then download icons and install it in one of these "~/.icons" or "/usr/share/icons/" location. If you find any missing icons or problem with this icon set then report it to creator via linked page and hopefully it will get fixed soon.
  • Ashes Is A Light Theme For Your Linux Desktop
    Ashes theme is based on Adapta and Flat-Plat theme but it includes the mixture of blue and pink color scheme with gray search entity. Usually derived themes always try to make better and enhanced version by the person who forked it, to make desktop much perfect and elegant, same thing goes for this theme, it looks and feels great on almost every desktop. Mainly it is designed to work in Unity and Gnome desktop but it can also work in other desktops such as Cinnamon, Mate, and so on. For the Gnome desktop creator have added the dark title-bar/header-bar support, so you can enable Global-Dark-Theme using Gnome-Tweak-Tool, if you prefer dark title-bars. If you are using distribution other than Ubuntu/Linux Mint/its derivatives then download theme from here and install it "~/.themes" or "/usr/share/themes/" location. If you find any kind of bug or issue within this theme then report it to creator and since this theme is in active development hopefully it will be fixed soon.

KDE: QtWebEngine on FreeBSD, KDE PIM, Akademy 2017, Craft, Accessibility, Comics Manager for Krita, Progress on Kube

  • QtWebEngine on FreeBSD
    Tobias and Raphael pushed the button today to push QtWebEngine into FreeBSD ports. This has been a monumental effort, because the codebase is just .. ugh. Not meant for third-party consumption, let’s say. There are 76 patches needed to get it to compile at all. Lots of annoying changes to make, like explaining that pkg-config is not a Linux-only technology. Nor is NSS, or Mesa, while #include is, in fact, Linux-only. Lots of patches can be shared with the Chromium browser, but it’s a terrible time-sink nonetheless.

  • KDE PIM in Randa 2017
    Randa Meetings is an annual meeting of KDE developers in a small village in Swiss Alps. The Randa Meetings is the most productive event I ever attended (since there’s nothing much else to do but hack from morning until night and eat Mario’s chocolate :-)) and it’s very focused – this year main topic is making KDE more accessible. Several KDE PIM developers will be present as well – and while we will certainly want to hear other’s input regarding accessibility of Kontact, our main goal in Randa will be to port away from KDateTime (the KDE4 way of handling date and time in software) to QDateTime (the Qt way of handling date and time). This does not sound very interesting, but it’s a very important step for us, as afterward, we will finally be free of all legacy KDE4 code. It is no simple task, but we are confident we can finish the port during the hackfest. If everything goes smoothly, we might even have time for some more cool improvements and fixes in Kontact ;-)
  • Services Collaborating Openly at Akademy 2017
    At the recently concluded Akademy 2017 in the incredibly hot but lovely Almería, yours truly went and did something a little silly: Submitted both a talk (which got accepted) and hosted a BoF, both about Open Collaboration Services, and the software stack which KDE builds to support that API in the software we produce. The whole thing was amazing. A great deal of work, very tiring, but all 'round amazing. I even managed to find time to hack a little bit on Calligra Gemini, which was really nice. This blog entry collects the results from the presentation and the BoF. I realise this is quite long, but i hope that you stick with it. In the BoF rundown, i have highlighted the specific results, so hopefully you'll be able to skim-and-detail-read your specific interest areas ;)

  • My Adventures on Crafting part III – Craft Atelier
    Once upon a time, I start o use Craft, an amazing tool inside KDE that does almost all the hard work to compile KDE Applications on Windows and MacOS.

  • Why YOU care about accessibility, and can help!
    Accessibility (a11y for short) seems like a niche area of concern for many people.

The sidewalks are thoughtfully cut out for wheelchairs -- and those with luggage! and the kids riding skateboards, and...... the rest of us.
  • Writing a comics manager for Krita
    Those who know me, or at the least know my history with Krita is that one of the prime things I personally want to use Krita for is making comics. So back in the day one of the things I did was make a big forum post discussing the different parts of making a comic and how different software solves it. One of the things about making a comic is that is a project. Meaning, it is big and unwieldy, with multiple files and multiple disciplines. You need to be able to write, to draw, to ink, to color. And you need to be able to do this consistently.

OSS: Thankful For Free Software Developers, Mastodon Size, foss-gbg and More

  • People Should Really Be Thankful For Free Software Developers
    Users don’t usually realize the value of free software they get for free. Things like Linux, LibreOffice, Inkscape, GIMP and a lot of other free software may be essential in the daily life of each of us. However, we may not actually feel “pleasure” for those software developers who provided us with all of this. They may not feel the value of what they have. If you ask an engineer, a doctor, a professor, a teacher or a farmer to give you one of the products they do for free, probably they will just refuse. You won’t find a professor working full time in a university for free. You won’t find a civil engineer working on building houses for free. You won’t find a farmer giving you vegetables for free. However, you do find software developers giving it for you for free. Software are not developed by magic. Developing good software requires investing hundreds of hours in it. And although of all of that, we find a huge number of software developers who are ready to create free software for us. Investing just 100 hours in developing a small tool should worth $1500 (with a minimum wage of $15 per hour). So imagine how much it really costs to invest thousands of hours in such processes. Let’s make a small comparison.
  • Mastodon is big in Japan. The reason why is… uncomfortable
    It’s hard to say how fast Mastodon is growing, because it’s hard to say how big Mastodon is. The Mastodon Network Monitoring Project does its best to keep up, but servers come online and go down all the time. If you’re running a Mastodon server and don’t register or federate it (perfectly reasonable if you want a community just for people you invite) it won’t register on the project’s dashboard. So we might think of the 1.5 million registered users on ~2400 servers as the network’s minimum size. [...] Our team at the MIT Media Lab – Chelsea Barabas, Neha Narula and myself – are releasing a new report today on distributed publishing, titled “Back to the Future: the Decentralized Web” We end up speculating that the main barriers to adoption of decentralized platforms aren’t technical, but around usability. Most distributed publishing tools are simply too complex for most users to adopt. Mastodon may have overcome that problem, borrowing design ideas from a successful commercial product. But the example of lolicon may challenge our theories in two directions. One, if you’re unable to share content on the sites you’re used to using – Twitter, in this case – you may be more willing to adopt a new tool, even if its interface is initially unfamiliar. Second, an additional barrier to adoption for decentralized publishing may be that its first large userbase is a population that cannot use centralized social networks. Any stigma associated with this community may make it harder for users with other interests to adopt these new tools.

  • Chrome/Chromium Seems To Perform Better And Here Are Some Useful Extensions
    Since its launch in 2008, Google Chrome has now become the most popular web browser, leaving the competition way behind. Google Chrome is available for various operating systems such as Windows, Mac OS, and Linux. Linux is the most popular open source operating system, used by millions worldwide. Aside from being open source software, Linux is also customizable, which means users can fit it for specific purposes. Installing Chrome on Linux is not a direct process, but it is worth it. For one thing, Chrome is a very fast browser as compare to other browsers. It is also easy to access. Unlike in other operating systems, a straightforward installation of Google Chrome is not possible in Linux because it is not available via Software Manager in any Linux distribution, in order to install it you must download it from its official website. For example, if you wish to install Google Chrome in Ubuntu/Linux Mint, which are both most popular Linux distributions, you would have to open the terminal and run some specific commands one by one, or alternatively you can download deb file and double click to open it via installer.
