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.

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.

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

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.

  • Router Freedom at risk: Latvia allows restrictions to consumers' rights

    Latvia's reform of the telecom law weakens Router Freedom in the country. The national regulator, SPRK, has allowed ISPs to restrict the use of personal routers on the grounds of "technological necessity". We explain why this is problematic and what impact it can have for end-users' rights. Router Freedom is the right end-users have to choose and use their own modems and routers to connect to the Internet. Since 2020, European countries have been in a process of implementing this right within a reform of EU telecommunications law. In this context, Latvia has created a risky precedent against end-users' rights by allowing internet service providers (ISPs) to determine restrictions on the use of personal routers and modems based on "technological necessities". The FSFE has engaged with the Latvian regulator, SPRK, to stress the necessity to change the law as it represents a big loss for consumer rights.

  • Add Mycelium To Your Mesh Networks

    In many parts of the world, days after a good rainfall, it’s fairly common to see various species of mushrooms popping up out of the ground.

Its air of mystery and its vast reach are the inspiration for entire Star Trek shows and, of course, projects like this LoRa-based mesh network called Mycelium.

  • What packages are Needed to build the Kernel | Adam Young’s Web Log

    In my quest to automate the testing of the Linux Kernel, I need to automate the build of the Linux Kernel. To build the Kernel, you need the requisite packages. What are they? Let’s find out. I am staring with a Baremetal Fedora Image. It has 344 packages installed already. I’m going to assume that this set is available when I do my automated build as well, or that the needed packages will get pulled in by dependencies. If not, I will find out when my automation fails to run and I will add them at that point. Most Fedora and CentOS based documents on building the Kernel have you do a group install of the “Development Tools” yum package group. I don’t want to do this for two reasons. First, I want to use the beaker format which just lists the packages in the job description. Second, I want to minimize the non-required packages, and Development Tools is general purpose group for coding; not everyone needs everythingm, and I don’t want to put non-essential packages on the system.
