Learning piano pieces can take some time. For some piano players a difficult aspect of it is reading the notes. If one gets used to memorizing them, or (even worse) always writes the corresponding letter above them (e.g. “c” or […]
In this article we define and publish the exact pre-flop probabilities for each possible combination of two hands in Textas Hold’em poker. An online tool at tools.timodenk.com/poker-odds-pre-flop makes the data visually accessible.
In late 2017, small groups of our class were given the task to delve into the assembly language and write a program for the 8051 microcontroller, as part of the Low-Level Programming lecture. This post documents the project MOV is Turing-Complete: 4-bit […]
This post functions as a quick development update on the Math to Image Conversion Bot (on Telegram), the TeX math to image conversion tool (at tools.timodenk.com), and the API that serves them both. The objective is to convert TeX math-code into images.
The ShiftRegister PWM Library enables usage of shift register pins as pulse-width modulated (PWM) pins. Instead of setting them to either high or low, the library lets the user set them to up to 256 PWM-levels. This post serves as […]
The digit span test is a way of measuring the storage capacity of a person’s working memory: A testperson is visually or auditorily exposed to a sequence of digits one after the other. Right afterwards, the test subject has to […]
Cubic spline interpolation is a mathematical method commonly used to construct new points within the boundaries of a set of known points. These new points are function values of an interpolation function (referred to as spline), which itself consists of […]
According to the U.S. Census Bureau the average commute time for U.S. citizens who are neither working at home, nor walking or biking to work, is 25.9 minutes. My commute time from Karlsruhe to SAP is usually about 38 minutes one-way; […]
The International Space Station is orbiting our planet since 1998. One orbit takes only approximately 92 minutes and the ISS is sometimes visible at the night-sky. To the naked eye it looks like a bright star crossing the night sky in […]
The widely used Arduino IDE offers many easy-to-use functions, one of them is void digitalWrite(uint8_t pin, uint8_t val) . It sets one of the microcontroller’s pins to either high or low and serves well in many cases. However, it has a really poor performance, […]
