How to fix an unresponsive KDE Plasma taskbar

Today, I was coding for my startup, Caprycon , on my laptop running Kubuntu 26.04 LTS. I looked down at the bottom right of my screen to check the time and noticed it was stuck at 6:10 PM. Updating my date and time settings did nothing. When I tried to switch applications by clicking the icons on my KDE Plasma taskbar, they were unresponsive. That's when I realized the entire taskbar had frozen. Here is how to fix it. How to Fix an Unresponsive KDE Plasma Taskbar Press ALT + SPACE . This opens KRunner , which will appear as a drop-down search bar at the top of your screen. Enter the following

Vegetarian Chili

It's a slightly modified version of the chili recipe Adam Ragusea posted on his YouTube channel . I cook it every other week and it works perfectly both as a main or a side dish. When I first started cooking it, my daughter would request it over and over again, so it even became a meme within our family. 400 grams of canned kidney beans 400 grams of canned tomato pulp 3 large bell peppers 3 celery sticks 1 large onion 1 tablespoon of sugar 20 grams of dark chocolate 1 tablespoon of Worcestershire sauce Seasoning (salt, pepper, paprika, ...) 1 tablespoon of olive oil These are the basic ingredi

Launching Magit from IntelliJ IDEA

For a large portion of git operations I use daily, I find Magit ’s interface much more convenient than git’s own CLI or IntelliJ’s UI. Although, I don’t use Emacs for all my coding projects, I’d like to have a shortcut to quickly open Magit for any git repository, either from a terminal or IDEA. When I’m in a terminal and need to open a file or a directory in Emacs, I call the following wrapper, which I have in my $PATH as emacsclient : #!/usr/bin/env bash # Bring Emacs frame to the foreground osascript << EOF tell application "System Events" tell application process "Emacs" set frontmost to t

Bouncing thoughts

I often have sleepless nights. It starts with a single thought, but then one thought leads to another and another, and soon it looks like a mini reactor with thoughts dividing and bouncing inside my head. Sometimes it's anxiety spiralling into life decisions. Often it's uncertainties or unresolved issues at work, or ideas about new projects. That may be because night is the only time when my brain is free from external stimuli and allowed to wander freely. Occasionally, I manage to redirect the thoughts and fall asleep. I used to practise meditation, and the techniques sometimes help to calm t

A take on transparency

A colleague of mine shared an interesting perspective on transparency the other day. It was in the context of decision-making in a corporate environment: It's not about everyone taking part in making the decision. It's not about telling everyone everything about what you're doing at every point during the decision-making process. It's about providing sufficient context and reasoning behind the decision—explaining why the decision was made. Too little information leaves people confused, anxious, and potentially resentful; too much can overwhelm or distract from what actually matters.

Quoting Joan Westenberg

When I write for social media, I'm writing for someone who is one thumb-flick away from a video of either a hate crime or a dog riding a skateboard. Everything I produce has to compete, in real-time, with everything else that could possibly occupy that user's attention. The incentives push toward provocation and emotional activation. The format actively punishes nuance, which means that a thoughtful caveat reads as weakness and any acknowledgment of uncertainty looks like waffling. – Joan Westenberg , The Case for Blogging in the Ruins.

File name completion in Emacs

The Emacs Carnival for February is hosted by Sacha Chua and its topic is “Completion”. Below is my entry for this month's carnival. Emacs has a myriad of ways to complete things for you in different contexts. While the one I’d like to share with you may seem trivial, the feature is so ingrained into my workflow so that I even forgot that it’s not part of the core Emacs functionality. I often switch from IntelliJ IDEA to Emacs (using a convenient shortcut ) just to use the feature. The feature provided by a wonderful cape.el package which extends the Emacs’ standard completion-at-point function

Optimising short screencasts using ffmpeg

For the previous post on file completion in Emacs I wanted to attach a short screencast demonstrating the feature in action. I recorded it with macOS's Screenshot app and then converted into gif using ffmpeg, so that it plays automatically: ffmpeg -i emacs-cape-file.mov emacs-cape-file.gif By default, the resolution of the videos recorded by Screenshot is quite high, so no surprise that the output gif turned out to be huge 1.4M . Even though it was only part of the screen recorded, the resolution was 1730x1658 , which is way more than I needed to publish it on a web page. To reduce the resolut

On Tesla Roadster

I think it’s yet another Ponzi scheme aimed at inflating the stock price of X. The demo is impressive, I must admit. Beyond that: a toy by the rich, for the rich at the expense of the rest of society. In a world that is burning in the flames of climate crisis, spending resources on such a bizarre and useless thing is simply immoral.

The Count Is the Constant

Somewhere in a cloud bucket sits the largest pi anyone has ever computed: 314 trillion digits. The count is the first thing to notice — the record is named after the constant it measures. 314 trillion. Somebody stopped at the number that starts the whole thing, which is either a joke or a signature, and I choose to read it as both.

The Threshold Where Chaos Loses

A quantum computer is usually described as a machine that runs a calculation and then tells you the answer. The hard part is what happens in between: errors creep in while the calculation is still running, and a machine that cannot catch them mid-flight will never be trusted with anything long. So a team from Rutgers and IBM tried something that sounds obvious and turns out to be very hard — they made the machine check itself while it ran.

The Proof That Checks Itself

A conjecture in computer science stood for twenty-seven years, and then it fell twice in one day — to two different machines, in two different labs, neither of which knew about the other.
