    Simply NUC has launched a $639-and-up “Cypress” mini-PC with AMD’s Ryzen V2000 plus 2.5GbE, 2x HDMI, 2x DP-ready Type-C, 3x USB 3.2 Gen2, and a 128GB SSD for one of the 2x M.2 slots.

    Simply NUC (or SimplyNUC) has launched a Cypress Long Life Mini mini-PC, named for its 7-year supply guarantee. The system offers pre-installed Ubuntu or Win 10 running on AMD’s 7nm, octa- and hexa-core Ryzen Embedded V2000.

    Pricing starts at $639 for a Cypress LLM2v5Cy SKU with the hexa-core, 2.1GHz/3.95GHz V2516, $689 for the LLM2v6CY with the hexa-core, 3.0GHz/3.95GHz V2546, and $829 for the LLM2v8CY with the top-of-the-line, octa-core 2.9GHz/4.25GHz V2748. All these prices include 4GB RAM, a 128GB SSD, 1-year support, and either no OS or pre-installed Ubuntu.

  • Build A Dog Ball Launcher That Kinda Looks Like A Dog | Hackaday

    The design is straightforward. The 3D printed housing features a large funnel into which a ball can be dropped. A servo then holds the ball while a pair of rollers are spun up by brushed DC motors. After two seconds, the servo releases the ball towards the rollers which launch the ball out of the machine. A Raspberry Pi Pico runs the show, controlling the timing of the ball launch and varying the motor speed to change the distance the ball is launched on each firing.

  • Arm adds virtual testing platform for Corstone Cortex-A and -M ref designs

    Arm has launched an “Arm Total Solutions for IoT” initiative that combines its Cortex-A- and -M based Corstone SoC reference designs with a new “Arm Virtual Hardware Targets” platform for virtual, cloud-based testing.

    In 2018, Arm launched an Arm Corstone subsystem product line comprising prevalidated SoC reference designs that combine its core IP with security, debug, memory subsystems, and in some cases, NPUs. Now, Arm has expanded Arm Corstone with a cloud-based Arm Virtual Hardware Targets testing and development platform aimed at IoT. Together with a new Project Centauri ecosystem initiative for Cortex-M developers, the programs are wrapped up into an “Arm Total Solutions for IoT” umbrella platform.

  • 248: PinePhone Pro: Exclusive Interview with Pine64

    This week’s episode of Destination Linux, we’re being joined by Lukasz Ericenski of Pine64 for an Exclusive Interview about the new PinePhone Pro! Then we’re going to talk about NTFS improvements coming to the Linux kernel. Plus we’ve also got our famous tips, tricks and software picks. All of this and so much more this week on Destination Linux. So whether you’re brand new to Linux and open source or a guru of sudo. This is the podcast for you.

  • Amazon offered me half of what I paid for my Galaxy S20 FE 5G. The phone is so awful that I’m considering it. – BaronHK's Rants

    I’m considering a Pine Phone Pro.

    My spouse laughed at me when I said it runs GNU/Linux and lets you do whatever you want. It sounds like the anti-iPhone to me. No crAPPs. No vendor lock-in. No freemium junk.

    But Samsung has been going downhill for years. Now, they don’t even want to talk to you unless you have thousands of dollars for a phone that will be obsolete or broken in a matter of 24-36 months (the Z series).

    The Pine Phone Pro is going to be $399 and Amazon is offering me a $200 gift card for this Galaxy phone.

    Which is half of what I paid for it last year, but I’m considering it.

    The stupid thing barely even works at all since T-Mobile bought Sprint and put the T-Mobile Network Experience SIM card in it. The stupid thing malfunctions the worst when I have 5G turned on, but it’s not great in LTE mode either.

    When it can get a network signal, the piece of trash is either beeping at me because it’s Samsung wanting me to agree to a new EULA or use Microsoft products that are also trash that I don’t want. (With NSA backdoors.)

    In the past 5 years, Samsung phones have gone from a couple of crapplets, just disable them, whatever, to an entire phone screaming at you that you MUST use Microsoft products.

  • Arduino Brings USB Mouse to Homebrew computer

    When building your own homebrew computer, everything is a challenge. Ultimately, that’s kind of the point. If you didn’t want to really get your hands dirty with the nuts and bolts of the thing, you wouldn’t have built it in the first place. For example, take the lengths to which [rehsd] was willing to go in order to support standard USB mice on their 6502 machine.

Kernel: Slowdown, CephFS, and FS-Cache / CacheFiles

  • How a performance boost in Linux kernel for one family of Intel chips slowed its latest Alder Lake processors

    The mixture of performance and efficiency CPUs in Intel’s 12th-gen Core processors, code-named Alder Lake, hasn’t just been causing problems for some Windows gamers – it almost led to complications for Linux. Phoronix’s Michael Larabel noticed a performance hit in the kernel a fortnight ago – in a work-in-progress release candidate, we should stress – and a fix for the scheduling code landed a little later. It turned out the kernel suffered on Alder Lake chips due to a performance-enhancing tweak for another Intel processor family: the multiple-Atom-core-based Jacobsville. This year, Intel officially canned its Lakefield chips. These consisted of a performance core called Sunny Cove as well as Atom-class efficiency cores dubbed Tremont. Crucially, there are still multi-Tremont-core embedded processors out there, such as Snow Ridge. These are server and infrastructure-oriented components with up to 24 cores. The first proposed cut of kernel 5.16, specifically 5.16-rc1, contained a revision to the scheduler that makes it aware that some clusters of cores share a block of L2 cache – as seen in Snow Ridge and Jacobsville.

  • Testing the Linux Kernel CephFS Client with xfstests

    I do a lot of testing with the kernel cephfs client these days, and have had a number of people ask about how I test it. For now, I’ll gloss over the cluster setup since there are other tutorials for that.

  • Major Rewrite Of Linux's FS-Cache / CacheFiles So It's Smaller & Simpler - Phoronix

    As part of David Howells of Red Hat long-term work on improving the caching code used by network file-systems, he today posted a big patch series rewriting the fscache and cachefiles code as the latest significant step on that adventure. Howells posted a set of 64 patches for rewriting the kernel's fscache and cachefiles code. Linux's fsache is a general purpose cache used by network file-systems while cachefiles is for providing a caching back-end for mounted local file-systems. The Red Hat engineer has been working on this rewrite for more than the past year.

    This is certainly not the first ESP32 thermal printer solution, as there are various implementations including bitbank2 thermal printer Arduino connecting ESP32 and nRF52 boards to the printer over Bluetotoh LE, or a Arduino sketches to print bitmaps over serial or MQTT.

  • Generate Fully Parametric, 3D-Printable Speaker Enclosures | Hackaday

    Having the right speaker enclosure can make a big difference to sound quality, so it’s no surprise that customizable ones are a common project for those who treat sound seriously. In that vein, [zx82net]’s Universal Speaker Box aims to give one everything they need to craft the perfect enclosure.

  • Z80 Video Output Via The Raspberry Pi Pico | Hackaday

    Building basic computers from the ground up is a popular pastime in the hacker community. [Kevin] is one such enthusiast, and decided to whip up a video interface for his retro Z80 machine.

  • The Calculator Charm: Calculatorium Leviosa! | Hackaday

    Have you ever tried waving your hand around like a magic wand and summoning a calculator? We would guess not since you’d probably look a little silly doing so. That is unless you had [Andrei’s] cool gesture-controlled calculator. [Andrei] thought it would be helpful to use a calculator in his research lab without having to take his gloves off and the results are pretty cool. His hardware consists of a PocketBeagle, an OLED, and an MPU6050 inertial measurement unit for capturing his hand motions using an accelerometer and gyroscope. The hardware is pretty straightforward, so the beauty of this project lies in its machine learning implementation.
