I used System76’s Pangolin for weeks, and Linux was not the biggest problem
by Peter Reutemann 05 May '23

'After using System76’s Pangolin as my primary work laptop for nearly six weeks, I can tell you this: If you need a 15-inch Linux-focused laptop, this is the one to get. The Pangolin is a solid device, designed more for dependability and convenience than ultrabook portability or cutting-edge parts, but it still has reasonably modern hardware (especially its 144 Hz screen). The Pangolin and its native Pop!_OS are a showcase for how remarkably normal Linux can feel as a daily driver in 2023. Normal, and with lots of ports. It’s hard to do a nuts-and-bolts comparison of the Pangolin to most other laptops, due largely to benchmark comparability between Linux and most laptops running Windows or macOS. But it’s also not entirely necessary. There’s only one real version of the Pangolin available—one processor, one amount of RAM, then variable, user-expandable storage. We’ll show you how the Pangolin did on a couple tests. But how this laptop works for you is much more about what you’re bringing to it and what you're willing to put into customizing it to your liking. I came to the Pangolin as someone who has made a few attempts at using Linux as a daily driver. I know enough command line, vim, and Unix-based architecture to be conversant, and I have two Raspberry Pis that are constantly being improved. Still, I'm more hobbyist than practitioner. And yet the Pangolin presented no real problems as I used it for almost any task I needed to get done. Its combination of solid software and practical hardware choices make it an easy system to recommend, so long as you know you need Linux. Its maker-made operating system, Pop!_OS, almost never gave me problems, except when I was trying to make it run benchmarks. Starting with a rock-solid Linux install, where every bit of hardware is supported and functional, made me more eager to poke at the edges and see what I could customize.' -- source: https://arstechnica.com/gadgets/2023/05/review-system76-pangolin-is-a-solid… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

'sudo' and 'su' Are Being Rewritten In Rust For Memory Safety
by Peter Reutemann 02 May '23

'Phoronix reports: With the financial backing of Amazon Web Services, sudo and su are being rewritten in the Rust programming language in order to increase the memory safety for the widely relied upon software... to further enhance Linux/open-source security. "[B]ecause it's written in C, sudo has experienced many vulnerabilities related to memory safety issues," according to a blog post announcing the project: It's important that we secure our most critical software, particularly from memory safety vulnerabilities. It's hard to imagine software that's much more critical than sudo and su. This work is being done by a joint team from Ferrous Systems and Tweede Golf with generous support from Amazon Web Services. The work plan is viewable here. The GitHub repository is here.
