Intel hopes to burn newly open-sourced AI debug tech into chips

Tuesday 26th of October 2021 05:21:41 AM
Intel Labs has big plans for a software tool called ControlFlag that uses artificial intelligence to scan through code and pick out errors. One of those goals, perhaps way out in the future, is to bake it into chip packages as a last line of defense against faulty code. This could make the information flow on communications channels safer and efficient.

Tuesday 26th of October 2021 04:07:21 AM
Ubuntu Budgie is an official Ubuntu flavour. Budgie gets its name from the desktop environment it uses, the Budgie Desktop environment.

My experience installing Libero SoC in Ubuntu and Windows 10

Monday 25th of October 2021 11:35:37 PM
A few weeks ago, I received Microchip PolarFire SoC FPGA Icicle Kit with FPGA fabric and hard RISC-V cores capable of handling Linux. I wrote “Getting Started with Yocto Linux BSP” tutorial for the board, and I had initially titled the current post “Getting Started with FPGA development using Libero SoC and Polarfire FPGA SoC”.

A Look At Alacritty The OpenGL Powered Terminal Application

Monday 25th of October 2021 10:21:17 PM
There are more terminal applications for Linux systems than you can shake a stick at... And frankly, most of them are like choosing what socks to wear; very little difference, save maybe for some special purposes, like thermal socks, or tiling terminals...But, every once and a while I come across one that does things a little differently, and makes me curious to check it out further; such as Alacritty.

This Dynatron A39 TR4/sTRX4/SP3 heatsink has been working out very well for those needing to cool a Threadripper/EPYC system in a 3U or larger enclosure.

Indie dev finds that Linux users generate more, better bug reports

Monday 25th of October 2021 07:52:37 PM
An indie developer has found an interesting observation: Though only 5.8% of his game's buyers were playing on Linux, they generated over 38% of the bug reports. Not because the Linux platform was buggier, either. Only 3 of the roughly 400 bug reports submitted by Linux users were platform specific, that is, would only happen on Linux.

Use Rust for embedded development

Monday 25th of October 2021 05:43:39 PM
Over the past several years, Rust has gained a passionate following among programmers. Tech trends come and go, so it can be difficult to separate excitement just because something is new versus excitement over the merits of a technology, but I think Rust is a truly well-designed language. It aims to help developers build reliable and efficient software, and it was designed for that purpose from the ground up. There are key features you[he]#039[/he]ll hear about Rust, and in this article, I demonstrate that many of these features are exactly why Rust also happens to be great for embedded systems.

Build Kubernetes pods with Podman play kube

Monday 25th of October 2021 01:20:37 PM
Whenever Podman developers talk about its future, they always mention one topic—making it easier to test workloads with Podman and deploy them into Kubernetes. The primary way users jump between Podman and Kubernetes is by using Podman's generate kube and play kube subcommands. As the names imply, generate kube creates a YAML description of a Podman pod or container to run in Kubernetes. Conversely, the play kube subcommand allows you to run Podman pods based on a Kubernetes YAML file.

  • Newest Linux Optimizations Can Achieve 10M IOPS Per-Core With IO_uring - Phoronix

    Just one week ago Linux block subsystem maintainer Jens Axboe was optimizing the kernel to get 8 million IOPS on a single CPU core. He progressed the week hitting around ~8.9M IOPS per-core and began to think he was hitting the hardware limits and running out of possible optimizations. However, this week he is kicking things off by managing to hit 10 million IOPS!

  • Team Profile by KDE's Cornelius Schumacher

    What makes a great team? One important factor is that you have a balanced set of skills and personalities in the team. A team which only consists of leaders won't get much work done. A team which only consists of workers will not work into the right direction. So how can you identify the right balance and combination of people? One answer is the Team Member Profile Test. It's a set of questions which team members answer. They are evaluated to give a result indicating which type of team member the person is and where it lies in the spectrum of possible types.

  • Some users on Reddit report that Windows 11 loses Internet connectivity when trying to connect to NordVPN.
  • Pat Gelsinger's Open-Source Bias, Intel's Pledge To Openness [Ed: Intel is openwashing again, but leaks from Intel show that Intel is a foe, not a a friend. It's also rather ironic that Intel puts an "open" letter in a proprietary site of Microsoft, which is viciously attacking Free software. Intel is a Microsoft booster.]

    Ahead of Intel's inaugural Intel Innovation event taking place virtually later this week, Intel CEO Pat Gelsinger published an open letter to an open ecosystem. In this open ecosystem letter, Gelsinger talks up opennness and choice, adding, "This is why I fundamentally believe in an open source bias, which powers the software-defined infrastructure that transformed the modern data center and ushered in the data-centric era."

Raspberry Pi and Arduino Leftovers

  • Tackle The Monkey: Raspberry Pi Gets Round Screen | Hackaday

    You could argue that the project to add a round screen to a Raspberry Pi from [YamS1] isn’t strictly necessary. After all, you could use a square display with a mask around it, giving up some screen real estate for aesthetics. However, you’d still have a square shape around the screen and there’s something eye-catching about a small round screen for a watch, an indicator, or — as in this project — a talking head. The inspiration for the project was a quote from a Google quote about teaching a monkey to recite Shakespeare. A 3D printed monkey with a video head would be hard to do well with a rectangular screen, you have to admit. Possible with a little artistry, we are sure, but the round head effect is hard to beat. Honestly, it looks more like an ape to us, but we aren’t primate experts and we think most people would get the idea.

  • Move! makes burning calories a bit more fun | Arduino Blog

    Gamifying exercise allows people to become more motivated and participate more often in physical activities while also being distracted by doing something fun at the same time. This inspired a team of students from the Handong Global University in Pohang, South Korea to come up with a system, dubbed “Move!,” that uses a microcontroller to detect various gestures and perform certain actions in mobile games accordingly. They started by collecting many different gesture samples from a Nano 33 BLE Sense, which is worn by a person on their wrist. This data was then used to train a TensorFlow Lite model that classifies the gesture and sends it via Bluetooth to the host phone running the app. Currently, the team’s mobile app contains three games that a player can choose from.
