Astro Pi 2: New Raspberry Pi hardware with updated camera, sensors to head to the ISS this year

Filed under
GNU

Hardware

Good news for earthbound Pi-tinkerers hoping to get their code into orbit: a follow-up to 2015's Astro Pi is due to head to the International Space Station (ISS) this year.

Time has moved on a bit since the Principia mission of Tim Peake where the first units were installed aboard the orbiting outpost. While over 54,000 participants from 26 countries have since had code run on the hardware, the kit has fallen somewhat behind what is available on Earth.

To that end, some new units are due to be launched, replete with updated hardware. In this case, heading to orbit will be Raspberry Pi 4 Model B units with 8GB RAM, the Raspberry Pi High Quality Camera (a 12.3MP device) and the usual complement of gyroscope, accelerometer, magnetometer, humidity, temperature and pressure sensors for users to code against.

5 Reasons Purism's Librem Laptops Are More Secure Than Your Notebook

Filed under
GNU
Linux

If you're looking for a secure laptop computer, you have several options. Thumb readers, facial recognition, and built-in encryption all offer considerable security. But these features – typically backed up by the operating system – are prone to failure, one way or another. For example, facial recognition can be bypassed using various techniques.

Purism is a company that assembles Linux computers, complete with a secure operating system and hardware kill switches. These features – while eschewing potential points of entry found on other laptops – make Purism laptops particularly attractive to any user concerned about online privacy and security.

GIMP 2.10.28 is now released. This is a bugfix release, because we are giving most of our time and efforts to the development version (2.99.x).

Note: you may have noticed we skipped GIMP 2.10.26. A build bug has been discovered just after tagging the release. GIMP 2.10.28 is the same without the bug. We recommend against building and using GIMP 2.10.26.

2021 Is the Year of Linux on the Desktop

Filed under
GNU
Linux

It's the year of Linux on the desktop! Thirty years into the life of Linux, it seems like people have said that every year. But now it's really true, and it's true because Linux found its real niche—not as a political statement about "free software," but as a practical way to enable capable, low-cost machines for millions.

Linux was founded on the desktop, as one man's project to create an alternative OS for his Intel-based PC. So it's understandable that Linux fans have been focused on desktops and laptops as a sign of success—and not, say, servers, or IoT, or drones. They can finally rest easy. Walk into any school now, and you'll see millions of Linux machines. They're called Chromebooks.

Chrome OS and Android are both based on the Linux kernel. They don't have the extra GNU software that distributions like Ubuntu have, but they're descended from Linus Torvalds' original work. Chromebooks are the fastest growing segment of the traditional PC market, according to Canalys. IDC points out that Canalys' estimates of 12 million Chromebooks shipped in Q1 2021 are only a fraction of the 63 million notebooks sold that quarter, but once again, they're where the growth is. Much of that is driven by schools, where Chromebooks dominate now.

Schoolkids don't generally need a million apps' worth of generic computing power. They need inexpensive, rugged ways to log into Google Classroom. Linux came to the rescue, enabling cheap, light, easy-to-manage PCs that don't have the Swiss Army Knife cruft of Windows or the premium price of Macs.

  • How to scale GRUB menu on 4K displays

    Several weeks ago, I installed Kubuntu 20.04 on my IdeaPad Y50-70, a somewhat old but rather capable 15.6-inch laptop with a 4K screen resolution. Predictably, the device wasn't usable in its native screen mode, and I had to make everything bigger, scaling and all that. In the end, I managed to create an ergonomically comfortable setup, with two exceptions - the login menu, and the boot menu. The former gave me some grief, but I was able to get it sorted. With GRUB, there were more problems. One, the menu wouldn't show, even though I had a dual-boot configuration in place. Two, the menu was tiny, with the text barely readable. So I embarked on a journey of GRUB modifications, hence this tutorial. Let me show you how you can make the GRUB menu bigger on HD/UHD displays.

  • Use this Linux command-line tool to learn more about your NVMe drives | Opensource.com

    NVMe stands for Non-Volatile Memory Express, and it refers to how software and storage communicate across PCIe and other protocols, including TCP. It's an open specification led by a non-profit organization and defines several forms of solid-state storage. My laptop has an NVMe drive, as does my desktop. And they're fast. I love how quickly my computers boot and how quickly they're able to read and write data. There's no perceptible delay. It also didn't take long for me to get curious about the technology driving this ultra-fast storage, so I did a little investigation. I learned that NVMe drives consume less power while delivering much faster access to data compared to even SSD drives over SATA. That was interesting, but I wanted to know more about my particular NVMe drives, and I wanted to know how they compared with other drives. Could I securely erase the drive? How could I check its integrity? Those questions led me to an Internet search that yielded an open source project with a collection of tools to manage NVMe drives. It's called nvme-cli.

  • How to Install FreeRADIUS and Daloradius on Ubuntu 20.04 – VITUX

    RADIUS is a AAA (authentication, authorization, and accounting) protocol that helps in controlling network access. In other words, RADIUS protocol is used for connection management between the Network Access Server (NAS) and Authentication server. The connection between two ends(NAC-NAS or NAS-Authentication server) is initiated after a successful negotiation on the network layer by exchanging packets containing necessary information such as NAS identification, authentication port number etc. In simple words, it can be said that RADIUS provides authentication, authorization, and account information from an Authentication server to a device requesting access.
