  • FUUG grant for Obnam development: what happened then

    In September, The FUUG Foundation gave me a grant to buy some hardware for Obnam development. I used this money to buy a new desktop-ish machine, see below for details. It's sat in a corner, and I use it as a server: it's not normally connected to a monitor or keyboard. It runs Obnam benchmarks. Before this, I ran Obnam benchmarks and experiments on my laptop, or on BigV virtual servers donated by Bytemark.s

  • Why Many Still Turn to Private Servers for Testing Environments

    With the evolution of the cloud, it may come as a surprise to some that there are so many businesses still using dedicated servers. In fact, according to Zephyr's annual How The World Tests Report, nearly half of respondents host their test environments in their private servers, while 36 percent chose a mix of cloud and hardware solutions. The question, then, is what conditions do these organizations have and why are private servers so essential to their workflows?

  • License Plate Tracking Has Gone Open-Source

    Computer vision-assisted license plate reading seems to be a favorite spectre of a certain sort of privacy worrier, at least anecdotally speaking. Something to do with its potential for tracking and profiling an activity that seems to make Americans in particular feel their most, uh, liberated (driving cars).

    The technology has had a steady uptake among law enforcement agencies, who of course think it's wondertool for busting crimes, but now an open-source implementation is starting to make some waves in the developer world and beyond. This is OpenALPR, and, as Mike James notes at I-Programmer, it's not a new thing but is getting some new attention in the wake of a recent code release. LPR is here for the masses and it's incredibly easy to use.

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
