Kex

I have implemented a game from my childhood days with Svelte and will go into a few details. KEX (Kern Explosion) is about using chain reactions to win over your opponents' atoms and in the end the entire game field.

Woven basket

In this article we learn how to build weaved 2D shapes with Svelte and SVG and transform those into 3D woven basket solids using OpenSCAD. And while the circular basket is quite easy, complexity grows when it comes to a rounded, rectangular basket.

Genuary 2024

I participated with submissions for the first ten days in Genuary 2024. It was quite stressful and charming, but I did stop when I became sick, so here are my thoughts on this online event.

Ortenau.IT Meetups 2023

I took up my initiative again and organised two more local tech meetups in 2023. And both combined a technical with a 'coaching' or soft skills topic, which I think seems to be a pretty brilliant mix and both were really well received.

At the Scrum UserGroup Meetup in Freiburg, Marc Bleß, author of two books on Agile games, led an evening focused on the benefits of playing games as a tool for coaching. Attendees played icebreaker games, Business Value Poker, Fearless Journey, and SIN Obelisk among others.

Futurice has settled in Freiburg and establishing their (meetup) culture there as well. This first kickoff Tech Meetup in Freiburg organized together with the local Scrum UserGroup had a great mixture of content, networking and a super nice location.

Link more circles

By seamlessly connecting multiple circles, we can draw a wavy path and build beautiful shapes out of it, first in two-dimensional SVG/Svelte and then in 3D.

Link circles

How do we get a smooth connection of arcs? Is this the moment for the Pythagorean theorem? We'll find out with some Maths and SVG/Svelte Geometry.

Intersecting rectangles

What's the size of a rotated and cropped rectangle? Another problem already solved, but now with some visual demos around the mathematic algorithms behind the solution.

Circle Inversion and Steiner Chain

I saw a tweet about a Steiner chain and had to come up with this new blog post how to do this using circle inversion, which by itself offers a bunch of new possibilities to become creative.

Tech Radar

Not the latest trend, but tech radars are currently or still finding their way into the management level. And with Svelte this kind of visualization is very easy to create.

The Ikigai model

What motivates you to stand up in the morning and go to work? Some weeks ago I joined another Scrum UserGroup online meetup from Karlsruhe where Veit Richter's current program is all about this question and the Ikigai model.

Block Puzzle

It's already two years I encoutered Svelte and one of the first things I've playes with was an implementation of an addictive casual game I played back then and still sometimes.

Demos Section

Instead of writing a full featured article each time I come up with an experiment, I now introcude a new section to my website for that called Demos. Enjoy!

Merry Christmas

Every year we come up with a creative X-mas card for 17 years already. This years card was inspired by the previous post about String Art and done with needle and a thread and some Pixelmator magix afterwards.

String Art

Winter has started, sometimes dreadful weather, just the time to tinker something. How about string art with needle, thread and thin cardboard? I'll show you that it has a lot in common with computer graphics.

Bezier curves

Well, here's one more post about a more general concept in computer graphics, bezier curves, and how easily they are constructed using the De-Casteljau algorithm. All explained using demos built with SVG and Svelte.

Linear interpolation

Whie thinking about another topic to write about at my still new blog, I came across some basic concept in computer graphics which is linear interpolation. I was not sure whether I need to introduce this before going straight into the topic. So here's something about lerp().

Pixel font fun

Once I had my LED matrix running with node.js I came up with other ideas what to display, so I stumbled over pixel fonts. And voila, I created a font scroller, first for the LED matrix, later as a Svelte component to use in my blog.

The Joy of Tixy

For me Tixy.land was a huge source of inspiration and so it was for others as well. Isn't it amazing that beside formulas people came up with such a lot of projects, different renderers and even hardware hacks? And I also did a lot with Tixy.

Limitations as a source of Creativity

Every limitation is also a driver of creativity. Much easier than starting on a blank page is to become creative and derive something new out of restrictions. To overcome existing limitations or limits set by your own, can push your mind and come up with something new, something of value.

Draw tomatoes with Svelte and SVG

I don't like to eat Tomatoes, at least not the fruit itself, but I do like Ketchup or a well tomato soup. And I did not plan to come up, but ended with a kind of tutorial, how to make reactive and animated SVG graphics with Svelte.

ES6 Weirds

I started my own, maybe growing collection of weird or even unexpected but otherwise correct Javascript syntax. Maybe my findings are useful for you as well.

Collatz conjecture

Do you like Maths? And have you heard about 3n+1, yet? Today on Hacker News I stumbled over this youtube video about 'The Simplest Math Problem No One Can Solve'. There are different names for this algorithm…

Fear Free Development

Today I joined the online zoom event of the Scrum User Group Karlsruhe. It started at 9 am CET in the morning, because we listened to Emad Al Hajjeh from Sydney where it was 5 pm AEST. It was the first (online) meetup for me after quite a while…
