• 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!

• Rakudo Weekly News: 2021.43 Thank You

  Oleksandr Kyriukhin has released the 2021.10 version of the Rakudo Compiler, which includes all of the work of the new MoarVM dispatch mechanism. This is the culmination of more than 1.5 year work by many people, but mostly by Jonathan Worthington. A historic step forward that lays the groundwork on more efficient executing of Raku programs, and actually delivers on a number of improvements.

• 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.

• 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

• Fast Indoor Robot Watches Ceiling Lights, Instead of the Road

  To pull this off, [Andy] uses a camera with a fisheye lens aimed up towards the ceiling, and the video is processed on a Raspberry Pi 3.

• 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.

Security Leftovers

• New York Times Journalist Hacked with NSO Spyware

  Citizen Lab is reporting that a New York Times journalist was hacked with the NSO Group’s spyware Pegasus, probably by the Saudis. The world needs to do something about these cyberweapons arms manufacturers. This kind of thing isn’t enough; NSO Group is an Israeli company.

  Microsoft has released a blog on NOBELIUM attacks on cloud services and other technologies. CISA urges users and administrators to review [NOBELIUM targeting delegated administrative privileges to facilitate broader attacks] and apply the necessary mitigations.

• Securing the proxy API for Firefox add-ons

  Add-ons are a powerful way to extend and customize Firefox. At Mozilla, we are committed not only to supporting WebExtensions APIs, but also ensuring the safety and reliability of the ecosystem for the long term. In early June, we discovered add-ons that were misusing the proxy API, which is used by add-ons to control how Firefox connects to the internet. These add-ons interfered with Firefox in a way that prevented users who had installed them from downloading updates, accessing updated blocklists, and updating remotely configured content.
