  • Computer Science was always supposed to be taught to everyone, and it wasn’t about getting a job: A historical perspective

    C.P. Snow’s chapter (with Norbert Wiener of Cybernetics as discussant) predicted a world where software would rule our lives, but the people who wrote the software would be outside the democratic process. He wrote, “A handful of people, having no relation to the will of society, having no communication with the rest of society, will be making decisions in secret which are going to affect our lives in the deepest sense.” He argued that everyone needed to learn about computer science, in order to have democratic control of these processes.

    [...]

    I completely buy the necessity part and the basic skill part, and it’s true that CS can provide economic opportunity and social mobility. But that’s not what Perlis, Simon, Newell, Snow, and Forsythe were arguing for. They were proposing “CS for All” decades before Silicon Valley. There is value in learning computer science that is older and more broadly applicable than the economic benefits.

  • Open LMS Launches Pro-Bono Partnership With Pancare Foundation

  • Waterfox G4.0.3.1 update released with fix for bootstrapped extensions, menu bar issues [Ed: It's irresponsible to promote Waterfox in any way. It's covertly owned by a surveillance company, System1.]

    Waterfox has been updated to version G4.0.3.1. This release fixes some issues that users had reported in the previous build.

    Version G.4.0.2 of the web browser, which shipped at the beginning of this month, had a bug that prevented the installation of bootstrap add-ons. Waterfox would throw out an "addon is corrupt" error message, when users tried to install the legacy extensions. Waterfox G4.0.3.1 update resolves the issue. The latest version also patches a bug that was preventing previously installed bootstrap add-ons, from loading upon the next restart, they were getting disabled by the application.

    You may have come across an issue in Waterfox G 4.0.2, that caused the menu bar to be displayed partially off the screen, in maximized mode. It also resulted in tabs listed on the menu bar. Both of these issues have been fixed in Waterfox G4.0.3.1. Users who wish to use bootstrap extensions, can find forked versions of some popular add-ons at this page. The update introduces a patch for a problem that was preventing the Copy Tab Link option from working. There is still no option to toggle the menu bar icons.

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
