Ubuntu Used to Detect Gravitational Waves at LIGO Experiment

Ubuntu

Ligo (Laser Interferometer Gravitational Wave Observatory) may not get the same kind of attention in the media as other physics experiments, but it should. It's designed to detect gravitational waves, and it looks like the scientists are also using Linux (Ubuntu) to do that.

Share your software, says NASA guru

He said instead of software’s inherent value being its cost, it was better as a means to an end. “The value isn’t in the software, it’s in the utility that the software provides.”

“My call to action is ... is there something in your portfolio of products or services that you can open source.”

World record set for 100 TB sort by open source and public cloud team

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

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.

The OSRF plans to add ARM support to the Robot Operating System (ROS), starting with the Snapdragon 600 running Linux in Q4, followed by Android in 2015.

The Open Source Robotics Foundation (OSRF), which maintains the open source Robot Operating System (ROS) and oversees the ROS.org website, has announced the first formal support for an ARM target. The organization will add support for the Qualcomm Snapdragon 600, a smartphone-oriented, quad-core, Cortex-A15-like system-on-chip running up to 1.7GHz, also referred to as the APQ8064 and S4 Pro.

GNOME Desktop: Flatpak and Random Wallpaper Gnome Extension

  • Flatpak in detail, part 2
    The first post in this series looked at runtimes and extensions. Here, we’ll look at how flatpak keeps the applications and runtimes on your system organized, with installations, repositories, branches, commits and deployments.
  • Flatpak – a history
    I’ve been working on Flatpak for almost 4 years now, and 1.0 is getting closer. I think it might be interesting at this point to take a retrospective look at the history of Flatpak.
  • Random Wallpaper Gnome Extension Changes Your Desktop Background With Images From Various Online Sources
    Random Wallpaper is an extension for Gnome Shell that can automatically fetch wallpapers from a multitude of online sources and set it as your desktop background. The automatic wallpaper changer comes with built-in support for downloading wallpapers from unsplash.com, desktopper.co, wallhaven.cc, as well as support for basic JSON APIs or files. The JSON support is in fact my favorite feature in Random Wallpaper. That's because thanks to it and the examples available on the Random Wallpaper GitHub Wiki, one can easily add Chromecast Images, NASA Picture of the day, Bing Picture of the day, and Google Earth View (Google Earth photos from a selection of around 1500 curated locations) as image sources.

KDE: QtPad, Celebrating 10 Years with KDE, GSoC 2018

  • QtPad - Modern Customizable Sticky Note App for Linux
    In this article, we'll focus on how to install and use QtPad on Ubuntu 18.04. Qtpad is a unique and highly customizable sticky note application written in Qt5 and Python3 tailored for Unix systems.
  • Celebrating 10 Years with KDE
    Of course I am using KDE software much longer. My first Linux distribution, SuSE 6.2 (the precursor to openSUSE), came with KDE 1.1.1 and was already released 19 years ago. But this post is not celebrating the years I am using KDE software. Exactly ten years ago, dear Albert committed my first contribution to KDE. A simple patch for a problem that looked obvious to fix, but waiting for someone to actually do the work. Not really understanding the consequences, it marks the start of my journey within the amazing KDE community.
  • GSoC 2018 – Coding Period (May 28th to June 18th): First Evaluation and Progress with LVM VG
    I got some problems during the last weeks of Google Summer of Code which made me deal with some challenges. One of these challenges was caused by a HD physical problem. I haven’t made a backup of some work and had to rework again in some parts of my code. As I already knew how to proceed, it was faster than the first time. I had to understand how the device loading process is made in Calamares to load a preview of the new LVM VG during its creation in Partition Page. I need to list it as a new storage device in this page and deal with the revert process. I’ve implemented some basic fixes and tried to improve it.

Open Hardware: Good for Your Brand, Good for Your Bottom Line

Chip makers are starting to catch on to the advantages of open, however. SiFive has released an entirely open RISC-V development board. Its campaign on the Crowd Supply crowd-funding website very quickly raised more than $140,000 USD. The board itself is hailed as a game-changer in the world of hardware. Developments like these will ensure that it won't be long before the hardware equivalent of LEGO's bricks will soon be as open as the designs built using them. Read more
