Filed under
SciFi

The myPalletizer uses a USB type C port to communicate with a computer to receive commands. Furthermore, it offers several programming languages to accommodate its users. For beginners, there is support for a block-based programming language similar to Scratch. Elephant Robotics offers several libraries compatible with C, C++, Python, JavaScript and the open source robotic platform ROS for more advanced users.

Elephant Robotics offers a gitbook page that offers documentation for all their products including the myPalletizer. Refer to their GitHub for firmware documentation.

Help with COVID-19 research using Folding@home on Linux

Filed under

Right now, every human on the planet is affected in some way by the COVID-19 pandemic. Many people are looking for ways they can help. People are making masks and starting projects to invent or provide critical equipment. One thing you can do is donate what you have. If you're like me, you have computing hardware sitting idle much of the time—that's a resource that can contribute to finding a solution to the COVID-19 pandemic, as well as things like Alzheimer's disease and cancer.

[...]

Folding@home started in 2000 with volunteers donating CPU and GPU time on computers that would otherwise be idle to work on things like creating antibiotics and curing cancer, and since then has made many important contributions. Currently, Folding@home makes more than 100 petaflops of processing power available to researchers. One current high-priority project is the research being done to find ways to combat the COVID-19 pandemic.

The Folding@home software can be installed on almost any computer. There are client downloads for Windows, macOS, and Linux. There is a VMware appliance. There are also projects to get the client running on Android and a Chrome plugin. There's even a Docker image.

In this article, we’ll look at the Linux install and configuration, and we’ll look at a headless install for CentOS 7 that you can use to build multiple VMs.

9 open source robotics projects

Open source isn't just changing the way we interact with the world, it's changing the way the world interacts back with us. Case in point: open source robotics.

Robots are playing an increasing role in our world, and while we perhaps haven't reached the utopian future with robotic housekeepers imagined for us in the Jetsons, robotics are making advances in fields that fifty years ago would have been completely unimaginable.

Linux-based bipedal robot endures kicks and dodgeball attacks

OSU demonstrated its speedy, bipedal ATRIAS robot withstanding a barrage of kicks and dodgeballs. ATRIAS runs on ROS and a real-time Xenomai Linux kernel.

Researchers at Oregon State University’s Dynamic Robotics Laboratory have demonstrated their Linux-driven ATRIAS robot withstanding a considerable beating while keeping its cool. OSU recently posted videos of its unusual torture testing procedures, which include human kicks and a barrage of dodgeballs, as reported by IEEE Spectrum. Eventually, the human-sized bipedal robot is knocked from its feet, but not before it absorbs a lot of hits. The robot protects itself with strategies such as side stepping and hopping on one foot

Linux for Astronomers

I've looked at specialty distributions that were created for engineers and biologists in previous articles, but these aren't the only scientific disciplines that have their own distributions. So in this article, I introduce a distribution created specifically for astronomers, called Distro Astro. This distribution bundles together astronomy software to help users with tasks like running observatories or planetariums, doing professional research or outreach.

From the very first moment of booting up Distro Astro, you will notice that this distribution is aimed at astronomers. The look and feel of items, from the boot splash screen to wallpapers and screensavers, have all been given an astronomical theme. Even the default wallpaper is a slideshow of Hubble images.

Imitate Fake Hollywood Terminal Hacking Melodrama with This Amazing App for Ubuntu

We all know that Hollywood movies are the worst place to see some accurate depiction of anything from real life and that includes computer terminals. Well, there is a solution for that now and we can only hope that some misguided producer will see the new "hollywood" package made for this exact purpose.

Hollywood movie producers invest a lot of time and money in custom interfaces and GUIs that don't really do anything, but they think they’re nice and interesting on film. Most of the time, someone is hacking away by typing frenetically while windows with crazy stuff open and close. This is why this kind of image is now seared into the public's consciousness and hacking looks more exciting than in real life. It isn't.

NASA’s R2 bot to receive legs via SpaceX

SciFi

The 330-pound Robonaut 2 measures 3 feet, 4 inches tall from the waist, and is equipped with more than 350 sensors. Its stomach-located brain runs Linux on 38 PowerPC-based processors. The robot is operated remotely by humans, using the Robonaut Tele-operation System (RTS). This telerobotics system requires a ground- or space-based user to wear a 3D visor, vest, and pressure-sensitive gloves. (For more on the R2, see our original coverage.)

According to the OSRF, the R2 team also uses the open source Gazebo simulator to simulate R2 for development and testing. NASA and ROS.org released their Gazebo models of the R2 and the ISS as open source.

cnet.com: Think how awesome it was the first time you saw a lightsaber in action. Or how your mind was officially shredded when Neo mastered the Matrix. Technology in movies is cool. But for every thrilling example of cool-ass tech, Hollywood seems to produce a tired, dated cliche.

  • How to install go1.19beta on Ubuntu 22.04 – NextGenTips

    In this tutorial, we are going to explore how to install go on Ubuntu 22.04 Golang is an open-source programming language that is easy to learn and use. It is built-in concurrency and has a robust standard library. It is reliable, builds fast, and efficient software that scales fast. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel-type systems enable flexible and modular program constructions. Go compiles quickly to machine code and has the convenience of garbage collection and the power of run-time reflection. In this guide, we are going to learn how to install golang 1.19beta on Ubuntu 22.04. Go 1.19beta1 is not yet released. There is so much work in progress with all the documentation.

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
