Turbocharging Kalendar — Kalendar devlog 15

Filed under
KDE

This week, we have focused on one thing: speed. From UI additions to under-the-hood improvements, Kalendar is now quicker to use and faster to act than ever!

A lot of this week has been spent profiling Kalendar, finding hotspots, and minimising them. As a result, lots of tweaks now help Kalendar perform better, particularly when using the month and schedule views. By limiting the number of view resets each second, using less resource-intensive components, and eliminating cruft, Kalendar is now significantly faster.

  • 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!

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."

  • 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.

    RabbitMQ is a free, open-source and one of the most popular message broker software. It supports multiple messaging protocols and uses plugins to communicate with popular messaging solutions like MQTT. A message broker is an application that stores messages for an application. Whenever an application wants to send data to another application, the app publishes the message onto the message broker. RabbitMQ can be deployed in distributed configurations to meet high-scale, high-availability requirements. In this post, we will show you how to install and configure RabbitMQ message broker software on Debian 11.

  • How to Create an Amazon Machine Image (AMI) and use it on AWS

    An Amazon Machine Image (AMI) provides the information required to launch an instance. An EC2 instance can not be launched without an AMI. We can create as many instances as we want from a single AMI when we need multiple instances with the same configuration. To create an instance we can use readily available AMI or we can create our own AMI. To create a custom AMI we need to first launch an instance using one of the available AMIs, make the required configuration on the instance and then use that instance to create an AMI. Instances launched from this new custom AMI include the customizations that we made when we created the AMI. We can create AMIs from either running or stopped instances. Once we create an AMI, we can either keep it private so that only we can use it, or we can share it with a specified list of AWS accounts. We can also make our custom AMI public so that the community can use it.
