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

SciFi

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.

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.

  • Ingo Juergensmann: Migrating from Drupal to WordPress

    If you can read this on planet.debian.org then migrating my blog from Drupal to WordPress was successful and the feed has been successfully changed by the Debian Planet Maintainers (thanks!). I’ve been a long term Drupal user. I think I started to use Drupal since it was included in Debian. At some point Drupal was removed from Debian and I started to use Serendipity instead. Later Drupal was included in Debian again and I moved back to Drupal. I think this must have been around Drupal 4 or Drupal 5. No idea. I even became active in the Drupal community and went to one of the first Drupal barcamps in Germany, namely in Cologne. This was shortly before Dries Buytaert started a business off of Drupal and went to the USA. I met with many devs of Drupal in Cologne and enjoyed the community and started with others a local Drupal User Group in Rostock. [...] So, after all the years my Drupal journey will come to an end. It was a long time with you. Sometimes joyful, sometimes painful. I wish you all the best, Drupal!

  • Red Kubes Container Platform Flies Open Source Flag

    Red Kubes, a Dutch-based startup, open sourced a free community edition of its Otomi Container Platform in a bid to remedy the ongoing complexity surrounding Kubernetes configurations. The scalability, agility, and speed-to-market advantages that Kubernetes offers have been handsome enough to capture a growing share of the enterprise market, but this very strength can become an Achilles heel for container deployments. In this sense, it’s far too easy – and common – to create thousands or even tens of thousands of containers across applications. Not only does this create an operational money pit, but management becomes a herculean feat to any container newbie.

  • Shots fired in disputes over OSS-as-a-Service

    Cloud services are the great disruptor of both IT organizations and vendors, and wrapping open source software around a service is the latest flashpoint. The open source development model has proven to be an incredible incubator of innovative software by democratizing and distributing the conception, design, implementation and debugging of new titles, advantages that were thoroughly explored more than two decades ago in the book, The Cathedral and the Bazaar. Although open source has since been adopted, encouraged and sponsored by every major software company, its origins were decidedly non-commercial with utopian overtones of liberating code from the tyranny of proprietary shackles. The earliest open source projects, notably Gnu Emacs and other tools from the Gnu Project, embraced this idealistic ethos with a restrictive, comprehensive license, GPL, that applies to derivative work using the code.

  • ROC and Precision-Recall curves - How do they compare?

    Both curves offer two useful information: how to choose the positive class prediction threshold and what is the overall performance of the classification model. The former is determined by selecting the threshold which yield the best tradeoff, in adequation with the prediction task and operational needs. The latter is done by measuring the area under the curves which informs about how good the model is, because by measuring the area under the curves, one computes the overall probability that a sample from the negative class has a lower probability than a sample from the positive class. With scikit-learn, the values can be computed either by using the roc_auc attribute of the object returned by plot_roc_curve() or by calling roc_auc_score() directly for ROC curves and by using the average_precision attribute of the object returned by plot_precision_recall_curve() or by calling average_precision_score() directly for PR curves.

Besides, I was sure that I would forget them in no time.

Open Hardware: Raspberry Pi, Arduino, Thomas Petazzoni (Bootlin) on Training

  • Qsync fixed on the Pi4 and FF compiled

    The Raspberry Pi4 does not have a hardware battery-backed clock, so relies on getting the date and time from an Internet time server. In EasyOS, Qsync is the utility that does that. At first bootup, QuickSetup has a checkbox to enable getting time from the Internet, which will launch Qsync. At first bootup on the Pi4, if you are going to connect to Internet via wifi, not ethernet, then there won't be an immediate Internet access. No problem, Qsync will run once the Internet connection is established. Qsync will run just once at bootup and after Internet connection. That's fine, but I couldn't understand why it would suddenly stop working. Then discovered that /etc/init.d/qsync was getting its executable-flag cleared.
