  • SINIT - The small cousin in the init family

    Sinit is part of the suckless tools, these tools was designed to be as small and efficient as possible. In the effort to make them small, they also do away with many features. It is for this reason, you may want to use them, it is also why you have to use something else. To deploy these, you will need to decide what features you need and compile them in. This is why you can push 'small' to the extremes with the sinit package. The downside is that you must do many things yourself, this includes finding that other system to control daemons.

  • Libcamera Is Becoming An Increasingly Viable Open-Source Camera Support Implementation

    With more cameras moving their image processing operations from micro-controllers to the CPU to save on manufacturing, libcamera was started last year to serve as an open-source camera support library across Linux / Android / ChromeOS for supporting these modern cameras.

    Libcamera is now working with the likes of UVC cameras, the Rockchip RK3399 hardware, the Intel IPU3, and work-in-progress Raspberry Pi support.

  • Zstd 1.4.4 Released With Faster Compression & Decompression Support

    Facebook has released Zstd 1.4.4 today as the newest implementation of their increasingly used Zstanard compression algorithm.

    While just a point release, Zstd 1.4.4 brings with it performance improvements. Zstd 1.4.4 is said to be about 10% faster for decompression performance compared to the earlier v1.4.3 release.

  • Technology as it Should Be

    In Imagine a world without apps Shira Ovide asks “a wild question: What if we played games, shopped, watched Netflix and read news on our smartphones — without using apps? Our smartphones, like our computers, would instead mostly be gateways to go online through a web browser.” This question can be extrapolated into a larger question: “What do we want from our technology?” The power of control by Big-Tech in the app store is but a small example of exploitation of our digital lives. If you don’t control the software, the companies who wrote that software control you. You become a digital prisoner. [...] The ability to encrypt your personal data with your own keys on your own device ensures that you fully control your digital life. With this as the starting point, you can then choose (aka opt-in) to share what you want with the people you want. This right is rooted in personal property rights, and is one of the most egregious abuses by Big Tech and those that have influence over them. If manufacturers, operating system developers, and software developers took a Hippocratic-like oath, one area society would agree on is the right that your personal data is your personal property and something you must retain control over and consent to share before it leaves your possession. Without regulatory assistance to protect personal data, society is left to fend for itself against the pressure from a multi-trillion dollar industry to exploit that personal data. There is no way to resist that pressure without the market creating convenient alternatives that honor that right while completely avoiding Big Tech. Purism creates products that are increasing in convenience daily, that fully protect you, and these products are the market answer to the worst abuses of Big Tech companies.

  • Arduino Blog » Control a wheelchair using an EEG headset and Arduino

    In an effort to help provide paralyzed patients with an easier way to operate their wheelchairs, these makers have developed a system that uses an OpenBCI brainwave cap to collect electroencephalogram (EEG) and electromyography (EMG) signals, literally from a user’s head. Data is then sent to a PC running OpenBCI software and passed along to an Arduino Uno via Bluetooth for control.

  • How To Install Redis on Linux Mint 20 - idroot

    In this tutorial, we will show you how to install Redis on Linux Mint 20. For those of you who didn’t know, Redis is an open-source in-memory key-value data store. It can be used as a database, cache and, message broker, and supports various data structures such as Strings, Hashes, Lists, Sets, and more. Redis provides high availability via Redis Sentinel and automatic partitioning across multiple Redis nodes with Redis Cluster. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you through the step by step installation of Redis on a Linux Mint 20 (Ulyana).

  • How to Download YouTube Videos in Linux | FOSS Linux

    YouTube is one of the websites with the most videos on the internet (as of writing this post, it is number one on the list).

Qt 6.0 Release Candidate 1 has the latest batch of bug/regression fixes to the Qt6 code-base. The very basic Qt 6.0 RC1 release announcement can be read on the Qt development list.

  • Porting from Qt 5 to Qt 6 using Qt5Compat library

    Porting from Qt 5 to Qt 6 has been intentionally kept easy. There has been a conscious effort throughout the development of Qt 6 to maintain as much source compatibility with Qt 5 as possible. Still, some effort is involved in porting. This short post summarizes some of the steps required when porting to Qt 6. In Qt 5 some of the classes already had existing replacements, and some classes got successors during the Qt 6 development phase. Therefore it might make sense to be able to compile your code with both the old and new Qt version. This can ensure that the amount of work where your code does not compile with either version is minimized, allowing your application or library to continue to work with Qt 5 and Qt 6. Another advantage could be that existing unit tests continue to work for most of the duration of porting, and regressions resulting from porting your code are easily distinguished from bugs introduced in Qt 6.
