GitHub account. I have a couple of hundred solutions to upload to the GibHub, though, notably solutions to LeetCode and Project Euler coding challenges, and HackTheBox and TryHackMe infosec challenges and machine writeups. This is a work in progress.
I was a Polish translation maintainer and coordinator of the open-source game: The Battle for Wesnoth. It is a turn-based strategy game with a fantasy theme. Wesnoth has many different campaigns and scenarios waiting to be played. It is a very mature and stable project, that had been actively developed for over a decade.
My contributions are tiny compared to the work of skilled volunteers that had created over years hundreds of beautifully animated units. Artworks are just awesome! ;-]
Crowd science is a way to distribute a scientific workload to the community of enthusiasts, who analyze the data in a specific way, guided in the project. Usually, there is little to no prior scientific knowledge required and the tasks are narrow in scope. People contribute for a number of reasons and I was participating because it was such a great opportunity to learn and push the boundary of science. Following are some projects I have participated in.
Zooniverse is the largest, most popular, and most successful platform hosting citizen science projects. I am not active right now, but I contributed 15k classifications of the scientific data so far.
The Andromeda Project goal was to identify star clusters in the M31 Andromeda, the closest spiral galaxy to Milky Way. The majority of identified clusters were never classified in any catalogue before, so every contribution has a significant impact on astronomy. I also contributed to Local Group Cluster Search with a similar goal to cover the remaining galaxies in the Local Group.
Galaxy Zoo is a large-scale galaxy research project where volunteers classify the shapes and features of galaxies. This improves understanding of how galaxies formed and their evolution. I have seen thousands of galaxies, and my favourite objects are spiral and merging galaxies. Elliptical galaxies are the largest, but they are rather smooth, oval-shaped, often with no distinct features.
Planet Hunters is all about searching for exoplanets. NASA's Kepler space telescope, now retired delivered a large amount of data. Volunteers have sifted through it over years and discovered thousands of new planets around stars outside of the Solar System. Transiting Exoplanet Survey Satellite (TESS) continues providing more data to this evolving branch of astronomy.
Space Warps was a very unique project. Massive galaxies warp space-time, bending light rays so that we can see around them. When it happens, the gravity lens is giving us a zoomed-in view of the distant universe behind the lensing galaxy. Lenses can help us investigate young galaxies more than halfway across the universe, as they form stars and start taking the familiar shapes we see nearby.
Planet Four project is a must for everybody interested in Mars. It is a great opportunity to explore the surface of the Red Planet. Using HiRISE data from the Mars Reconnaissance Orbiter (MRO), volunteers can study wind patterns on the Martian surface. The purpose of the project is to identify and measure features left by geysers of carbon dioxide bursting trough ground layer.
Snapshot Serengeti was an interesting window into the dynamics of Africa’s most elusive wildlife species. I helped classify all the native animals caught in millions of camera trap images collected in Serengeti National Park. I like animals and the project was a unique opportunity to understand their behaviour and learn about the great diversity of species living in Africa.
I am interested in science, especially astronomy, astrobiology, astrophysics, and cosmology. mostly on the popular science level, but I have contributed to real science myself in the past. I build and fly radio-controlled models and drones, which naturally leads to electronics, soldering, and DIY in general. I like hiking, and cycling and try to live a healthy lifestyle.
These are a few of the projects I worked on over the last years. Updates to this site weren't on my radar in recent years and I have more to add, so stay tuned!
I fly radio-controlled, 6-channel helicopters and drones, built either by myself from selected parts or from kits. They are very precise and powerful flying machines and fly in exactly the same way as real helicopters. There are no shortcuts in terms of rotor mechanics, control surfaces, etc.
I build foam planes. It is a cheap and simple method of constructing fixed-wing RC aircraft. Models are easy to fix in case of a hard landing and present a little risk due to low weight and density, as well as a soft structural material, which also offers some protection to the internal components. It is relatively easy to shape a good aerodynamic wing profile by sanding the foam.
I designed and built a workbench. The 3D model was created in Google SketchUp. It was a very interesting project and the first furniture I have ever made. The bench is very stable and stiff, however, I had to add diagonal supports in order to support the legs, because a 90-degree connection isn't rigid enough. Rookie mistake! ;] Drawer works smoothly, as it is mounted on ball-bearing sliders. The workbench is very handy, especially when I do soldering.
All my cats have been adopted or found homeless. Consider adopting a pet from a shelter if you can! ;] There are plenty of pets waiting for new owners in overcrowded shelters, so never buy from a pet store.
