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

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.

Parrot is prepping two Linux-based mini-drones: a $160 “Jumping Sumo” wheeled robot and a $100 “Rolling Spider” quadrocopter that can fly, roll, or climb.

Parrot, which last month announced a Bebop successor to its popular AR.Drone 2.0 quadrocopter, has released new information on two smaller, cheaper mini-drones that were originally unveiled back at CES in January. The Jumping Sumo and Rolling Spider will launch in August for $160 and $100, respectively.

The Next Open Source Battle Is Being Waged In The 3D Printing Industry

Filed under
OSS
Sci/Tech

More than twenty years ago, Linux began wending its way out of the primordial soup that was the early Internet and ensconcing itself in servers and workstations around the world.

After its creation in 1991 it took another eight years or so to be widely recognized, but during that period, arguments arose as to what Linux really was. Could Red Hat, a company founded in 1993, sell services around it? Who made money when you sold a CD containing the latest version of Mandrake Linux? Who owned code written on top of Linux for specific purposes? To the open source community, the answers to all those questions was “No one. The community owned Linux.”

Qt/KDE: Qt5 in Debian and Slackware, QtCreator on Android, KDE Discover, and Plasma's 10th Anniversary

  • moving Qt 4 from Debian testing (aka Buster): some statistics, update II
    We started filing bugs around September 9. That means roughly 32 weeks which gives us around 5.65 packages fixed per week, aka 0.85 packages per day. Obviously not as good as we started (remaining bugs tend to be more complicated), but still quite good.
  • [Slackware] Plasma5 – April 18 edition for Slackware
    The KDE-5_18.04 release of ‘ktown‘ for Slackware-current offers the latest KDE Frameworks (5.45.0), Plasma (5.12.4) and Applications (18.04.0). The Qt5 was upgraded to 5.9.5. Read the README file for more details and for installation/upgrade instructions. Enjoy the latest Plasma 5 desktop environment.
  • Perfect Debugging Experience with QtCreator on Android
    While I was working on a yet-to-be-announced super secret and cool Qt on Android project, I had to do a lot of debugging. This way I found that debugging Qt apps on Android using QtCreator was ok, but it had some issues, which was kinda frustrating.
  • Discover – Easily Install Software on KDE Neon Desktop
    KDE Discover is an Open Source GUI app installer that comes packaged with KDE Neon. It was particularly built from the ground up to be compatible with other modern Linux distros with emphasis on beauty and convenience. KDE Discover was also designed to allow for an intuitive User Experience as it features a clean and clear layout with a high readability value which makes it easy to browse, search for, install, and uninstall applications.
  • Almost 10 years of Plasma-Desktop
    Last week I was at work and start to listen my boss said: “We need to show this to our director”. So I went to my coworker table to see what was happening. So they were using Gource to make a video about the git history of the project. Gource is a software version control visualization tool. So that triggered in my mind some memories about a friend talking about Python and showing how the project as grow in this past years, but I never discovered about the tool that made that amazing video. So well, I started to make some Gource videos, and because my love about KDE Community, why not make one about it?

GNOME: Getting Real GNOME Back in Ubuntu 18.04, Bug Fix for Memory Leak

  • Getting Real GNOME Back in Ubuntu 18.04 [Quick Tip]
    Ubuntu 18.04 uses a customized version of GNOME and GNOME users might not like those changes. This tutorial shows you how to install vanilla GNOME on Ubuntu 18.04. One of the main new features of Ubuntu 18.04 is the customized GNOME desktop. Ubuntu has done some tweaking on GNOME desktop to make it look similar to its Unity desktop. So you get minimize options in the windows control, a Unity like launcher on the left of the screen, app indicator support among some other changes.
  • The Infamous GNOME Shell Memory Leak
    at this point, I think it’s safe to assume that many of you already heard of a memory leak that was plaguing GNOME Shell. Well, as of yesterday, the two GitLab’s MRs that help fixing that issue were merged, and will be available in the next GNOME version. The fixes are being considered for backporting to GNOME 3.28 – after making sure they work as expected and don’t break your computer.
  • The Big GNOME Shell Memory Leak Has Been Plugged, Might Be Backported To 3.28
    The widely talked about "GNOME Shell memory leak" causing excessive memory usage after a while with recent versions of GNOME has now been fully corrected. The changes are currently staged in Git for what will become GNOME 3.30 but might also be backported to 3.28. Well known GNOME developer Georges Stavracas has provided an update on the matter and confirmed that the issue stems from GJS - the GNOME JavaScript component - with the garbage collection process not being fired off as it should.
