  • But Think Of The (World Wide) Users! | Hackaday

    History is full of stories about technology that makes sense to the designer but doesn’t really fit the needs of the users. Take cake mixes. In 1929, a man named Duff realized that he could capitalize on surplus flour and molasses and created a cake mix. You simply added water to the dry mix and baked it to create a delicious cake. After World War II General Mills and Pillsbury also wanted to sell more flour so they started making cakes. But sales leveled out. A psychologist who was a pioneer in focus groups named Dichter had the answer: bakers didn’t feel like they were contributing to the creation of the cake. To get more emotional investment, the cake mixes would need to have real eggs added in. Actually, Duff had noticed the same thing in his 1933 patent.

    It is easy to imagine a bunch of food… scientists? Engineers? Designers?… whatever a person inventing flour mixes in the 1930s was called… sitting around thinking that making a mix that only requires water is a great thing. But the bakers didn’t like it. How often do we fail to account for users?

  • More Features Begin Lining Up For Fedora 36 - Phoronix

    With a few weeks having passed since the Fedora 35 debut, more feature work and planning around next spring's Fedora 36 are underway.

    Already accepted for Fedora 36 are some of the usual package updates that come as little surprise for living on the bleeding-edge. Among those updates are the likes of Autoconf 2.71, Java OpenJDK 17 as the system JDK, PHP 8.1, OpenSSL 3.0, and others.

    Some of the planned changes for Fedora 36 include using DNS-over-TLS where supported, replacing FBDEV kernel drivers with SimpleDRM, DNF/RPM copy-on-write enablement for all variants when running on Btrfs, and more. This Wiki page continues tracking the Fedora 36 changes that have been approved by the Fedora Engineering and Steering Committee (FESCo).

  • It’s Time More Linux Distros and DEs Become ‘Linus-Proof’

    The past few weeks have rattled the desktop Linux community.

    Popular tech YouTuber Linus, not Torvalds but Sebastian, decided to use Linux on desktop for a month. Linus Sebastian wanted to see if Linux has gotten to the point where it is user friendly enough that any tech nerd can pick it up and run? His focus was also on gaming on Linux because PC gaming is an area Sebastian covers a lot.

    That’s an interesting concept and many in the Linux community got excited because it was free publicity for desktop Linux to a wider tech audience.

Review: UBports on the PinePhone

At the end of 2021 I posted a review about the PinePhone and what it was like running the device's default operating system: Manjaro Linux featuring the Plasma Mobile interface. While I've had decent experiences with Plasma Mobile in the past, the combination of Manjaro, the PinePhone, and this interface left a lot to be desired. It was slow, it was unstable, and there were issues with the battery charge indicator. To make matters worse, the default applications were not polished or well named. It was a rough experience and, though I can see where there is hope for Manjaro on the PinePhone, I was eager to try something different. In the past I have had mostly good experiences with the UBports distribution. UBports is a community project which has continued Canonical's Ubuntu Touch operating system for smart phones and tablets. Since I've run UBports on devices which didn't have any more memory or processing power than the PinePhone, I was optimistic about trying out the PinePhone with this alternative distribution.

  • How to Enable MySQL/MariaDB Query Logging

    In this short and easy to follow guide, we cover how to enable MySQL/MariaDB query logging and save queries to a file. When using a database, it often happens that developers want to know what’s going on behind the scene. Whether it is for troubleshooting, performance tuning, or out of sheer curiosity. General query logs remain one of the most popular sources of auditing and diagnostic information in MySQL/MariaDB databases. After logging is enabled, the database server will write information to the log file when clients connect or disconnect, and it will log each SQL statement.

  • How to install Zotero on Ubuntu 22.04 or 20.04 LTS - Linux Shout

    Zotero is a reference management system and academic network, here we learn the steps to install Zotero in Linux such as Ubuntu 22.04 Jammy JellyFish or Ubuntu 20.04 Focal Fossa. Zotero is an open-source and free tool that helps in collecting, organizing, citing, and sharing research. It consists of two components: Zotero standalone (Mac, Windows, Linux) with a plugin for Firefox, Google Chrome, and Safari; Zotero web application: computer-independent access to your library, finding and setting up groups on specific topics (see collaboration), making contacts with others. The two components of this tool can be synchronized with each other. If you are often involved in extensive projects at work or have to write a large-scale work during your studies, you quickly lose track of the sources used. With Zotero, you keep all information together and create a clear library for your project without much effort. It is particularly suitable for literature research on the Internet and the direct transfer of the researched data and works in groups that want to manage literature together.

  • How to Copy Directory in Linux: (Beginner to Advance)

    While working in several operating systems, we use to add files and folders, cut, copy, edit and delete them as per our choice. Just like all these, the Linux system provides us the opportunity to copy a single folder to another folder even though the folder is empty or not. Therefore, we will discuss some easy methods to copy one directory to another in Ubuntu 20.04 system. Let’s have a fresh start by using the different ways to copy a directory from one place to another in Linux. For this particular purpose, we must open up the terminal shell as we are going to do all things in it. There are two ways to open it. One is from the activity search area and the other is the shortcut key “Ctrl+Alt+T”. Practice one of the mentioned methods to open it and start implementing the commands in it one by one.

Keyboards and Open-Source - Ignorance is bliss..

.

In my Keyboard Fun post from last year I talked a bit about my interest in mechanical keyboards. Since then, I played around with a few more keyboards/switches/keycaps/… Interesting enough, beside the actual hardware, naturally there is some software component to all these keyboards, too. Whereas most commercial keyboards still come with proprietary firmware, there is the trend within the keyboard enthusiast scene to go for open-source firmware. This allows you to properly update the firmware even from your Linux machine and do proper configuration of e.g. the keymap, too. Read more
