This is a toy private cryptocurrency project. General cryptocurrency values such as decentralization and scalability are not reaching the scale of global scale cryptocurrencies.

Have you ever thought of how the cryptocurrencies work? A few pieces of software and algorithms that random people run on their computers and are able to reach and mantain worldwide consensus. Well.. I did. And it was so fascinating to me that I wanted a piece of cake too. Not of Bitcoin or any other altcoin. I wanted my own cryptocurrency. So I developed it ;)). I wanted to have my own cryptocurrency, with my own protocol, my rules... and my coins <3. Since Proof-of-Work is a vulnerable approach (51% attack) to weak cryptocurrencies, I am developing more convenient proposal of my protocol to make users able to set a delegate to vote on their behalf regarding the network status with their stake (Delegated Proof-of-Stake), thus creating an effective and low-cost approach to reach a consensus for a private distributed network with low bandwidth and user count. This makes it possible to be secure and low-cost.

The project is in development for few years and there were some prototypes in use, but this will be the third and I hope the most robust private cryptocurrency network ever created (at least by me :P). The cryptocurrency is not and most probably be not perfect, so if you have any kind of proposal, I would very like to hear it from you. I also realized that a key factor was to make it fun to use for my friends/coworkers/family/whatever, Since I wanted to distrubute the coins without the mining process, I said: "let's make issuing coins fun!" - minting coins through website/mini-games/basically-anything with secure timestamping to prevent rapid inflation.

The project is in active development and has my best hopes it will turn out as my most pleasant private project. If you want to get insight into the project, have some questions or proposals, feel free to reach out to me :)


Czech Hydrometeorological Institute came up with a radar echo extrapolation nowcasting algorithm known as COTREC (and later proposed an upgrade called CELLTRACK). I was main developer of the software implementation for Meteopress s.r.o, engineered from scratch. Recreated with passion and multiple additional features :P

The program is developed in Go language and accepts two input images of t and t-10 to determine the default vector fields used for nowcasting prediction. The vector fields are applied to the image of t to determine the next positions of all dBZ values in the t+10, t+20,t+30... time-field. The program recursively divide the domain into smaller and smaller squares, which each one of them is calculated separatedly in the range of the parent square. The algorithm is effective to squares of t and t-10 correlation coefficient down to 0.7 (or similar) and fault-tolerant as it tests the recent correlation of the vector field with past calculations, thus it encodes an output with best vectors (current and past vectors are applied to t-10 and correlated with t domain).

I have developed a data hoarding tool for the Curseforge project hosting service. Originally for the sake of downloading and long-term storing modding software for the game of Minecraft.

I managed to develop a small script in Golang to download any minecraft mod (and possibly any project) from curseforge.com. My intention is to have my own copy of most favourite mods with all versions which are developed at this time - for long term purposes, I am not a fan of having most minecraft mods on one, same host. The script backups:

  • Download Page
  • Page of every version - because of changelogs
  • The mod itself

I plan to but all my mods to my 4TB+ redundant storage. I have tested this on Industrial Craft 2 and several other mods and it seems to work well. Those conditions has led me to a belief that some of you may want to have a backup copy of your favourite mods to ensure that in future those numerous modifications to this beautiful game can be backed up and possibly accessible from somewhere else in case that the biggest mod hosting website could be no option in future.
