Left click. Nothing happens. Left click. Nothing. Time for a new mouse? No. Instead, I repaired my Logitech MX Vertical mouse after many hours spent on troubleshooting, desoldering, soldering, and tinkering. But it was as educational as successful. Left click. Bliss! The mouse works again.
How to build a controller that automatically lands an airplane after approaching a runway via the Instrument Landing System (ILS) in GeoFS, the flight simulator?
How to build a controller that automatically puts an airplane on the glide slope from the beam of the Instrument Landing System (ILS) in GeoFS, the flight simulator?
How to construct a controller that automatically aligns an airplane with the runway using the deviation from the localizer beam of the Instrument Landing System (ILS) in GeoFS, the browser-based flight simulator?
Can’t spot the runway in GeoFS, the browser-based flight simulator? I fixed it by extending GeoFS with Google Maps, showing thousands of airports, as well as the extended centerline of the runway at the destination on the map.
A little quest to get every single button on my throttle quadrant to work with GeoFS, the browser-based flight simulator. A quest that not only taught me a little bit about evdev in Linux, but also led to many more quests later on.
Discovering all kind of difficulties of controlling the aircraft in the GeoFS flight simulator. As well as some remedies, whether in adjustments to software, hardware, or simply through deliberate practice.
A session with the flight simulator turned into a both entertaining and educational quest into control theory. Topics that I haven’t dabbled with for one, two, or even more decades. From a self-imposed lockdown to my first attempts to use PID controllers and fuzzy logic for steering the aircraft in GeoFS.
The “pomodoro technique” is a simple time management method, which requires a robust, simple-to-use timer, which doesn’t distract from the task at hand. For the third version, I constructed a plywood case to house the microcontroller, the 4-digit display, and the two buttons to control the timer.
Learning is often a process of rediscovering things. I enjoyed this process recently when trying to solve a combinatorial puzzle, in the pub, in the bus, and at home. A tale of allowing myself to explore, to tinker, and to be awed by the great thinkers of long gone times.
UK keyboards, for good reasons, do not come with keys for ÄÖÜ. Here is a quick-and-dirty fix to customize the xkb symbols map, tested on on Arch Linux.
The “pomodoro technique” is a simple time management method, which requires a robust, simple-to-use timer, which doesn’t distract from the task at hand. After the first prototype with the ATmega32-based RN-Control v1.4 experimental board, I built another prototype: this time with a 4-digit display.
The “pomodoro technique” is a simple time management method, however in my opinion completely lacks support from something essential: a robust, simple-to-use timer, which doesn’t distract from the task at hand. Thus, I built a prototype with the ATmega32-based RN-Control v1.4 experimental board.
If you ever wanted to use the right Ctrl button in Ubuntu 20.04 as an i3 modifier, and struggled with xmodmap, try editing the modifier mappings directly in /usr/share/X11/xkb/symbols/pc. It’s dirty, and may fail during software update─but meh until then it appears to work.
If you are a runner and desperate for a quick-and-dirty formula you can use in a Google Spreadsheet to convert running pace from minutes per mile into minutes per kilometer, this nerdy post will give the formula to you.
How to load Strava activities into Google Cloud BigQuery and visualizing the activities with Google Data Studio? This article is for (hobby) athletes interested in taking a walk through the Strava API, Google Cloud Platform and Google Data Studio; showing how to gain the freedom to explore and visualize the data you have been sweating for over years.
A review of Scott Page’s Model Thinking course, which has been overall entertaining, inspiring, informative albeit at times a bit repetitive when going through arithmetics. If you are interested in trying to make sense out of the complex world around you, this course might be for you.
Assume you are practicing for an exam. You could spend all your time left until the exam practicing (possibly too much), or you could spend almost no time practicing (likely too little). So how do you know when enough is enough? When can you stop practicing and yet be confident that you will pass the exam?
Today, I’ll demo how to train a logistic regression model in BigQuery ML. That is Machine Learning models written in SQL, and executed in BigQuery.
OpenAQ is publishing real-time air quality data from around the world to BigQuery. Today, I have poked around in the dataset to inspect air quality from many places of the world.
Whether you are an event organizer waiting for participants to turn up or whether you are a bus driver waiting for passengers running to catch the bus, there is a dilemma: if you are so kind and wait for everyone to arrive, you make everyone else wait. Let’s explain the dilemma with probability theory.
How do you analyse Strava activities—such as runs or bike rides—with Colab, Python, Pandas, and Matplotlib? In my fourth article on this topic, let’s invite scikit-learn and NLTK to the party, and apply some Machine Learning.
How do you analyse Strava activities—such as runs or bike rides—with Colab, Python, Pandas, and Matplotlib? In my third article on this topic, I am demonstrating how to visualize the data in different ways.
How do you analyse Strava activities—such as runs or bike rides—with Colab, Python, Pandas, and Matplotlib? In my second article on this topic, I am demonstrating how to group and aggregate the data in many different ways.
How do you analyse Strava activities—such as runs or bike rides—with Colab, Python, Pandas, and Matplotlib? In this post, I am demonstrating how to get started, and will give you a taster of what is possible with this state-of-the-art technology for data analysis.
