I wasn't a developer, but my work, private projects and interests made me to learn programming languages. Beneath I presents a few of my programs and some that was not made by me, but are useful.
In framework for Android apps, during creating View, a number of useful functions are invoked. They can be left with default implementation, but also can be overloaded with extra code. OS will call them in this order:
Docker has very rich syntax of its commands. Plenty of parameters, that we can pass, makes it very flexible tool but also a bit complicated. To make it simpler and not require passing a lot of stuff in automation scripts, that builds and runs containers, a kind of wrapper was made (docker compose). It use YAML file to define a list of...
Hey. If you came here, you probably need to convert your graphic to bunch of bytes. Of course, you can do it manually, but this is why we have computers. To do all this dirty job for us.
I made it basing on my colleague's (Radek) program called LCD Assistent (Oryginal site https://en.radzio.dxp.pl/bitmap_converter)

And basically you could stop reading here, but if you would like to hear longer story, please feel invited. Till recently, to fiddle with AVR processors and theirs code I was using AVR-Studio IDE. Unfortunately, the newest version is rather large in size. Also recently I have discovered a Visual Studio Code, lighter but still...
Sometimes we want to illustrate how many the same elements are in collection. Let's consider an example of children's pool with plastic balls. Let say there are 1000 of them and we can distinguish 5 colors (yellow, red, green, blue, white). To show, on one chart, how many balls are in each color, we need to take each ball and count....
Till recently, for writing code for given microcotroller, I was using dedicated GUI, which very often include embedded tools for compiling, building and quite often programming. As experience and complication of projects grow, one starts feeling natural need of test sophisticated architectures before uploading into device. This allows save time and money in future. That is why I wanted to...
Recently I was looking for some console application, that would allow me to capture images from internet camera into some graphic file. Maybe I wrongly asked google, but all I could find were large GUI apps, which didn't expose console interface. That is why I made CamCap (camera capture). Its usage is as simple as possible. All you need is to execute it from command line. It will detect...

My colleague asked me to make a remote thermometer for him. I haven't hesitated and decided to use well known RFM70 modules. Prototype worked as designed but during test in field, it turned out that range was to...
If you just need RFM70 library then you will find it below. If you want to read whole story, then don't stop.
Some while ago, colleague from work was looking for some radio modules to its project. One day he came with those tinny devices. When he brought them to work and said what they can do, I couldn't stop wondering theirs price to feature ratio. Immediately I ordered...
