+# Supported platforms
+
+To verify code portability, I selected the following platforms and languages:
+
+* C++: Linux, macOS, OpenWrt, Windows
+* JavaScript: Chrome, Firefox, Safari
+* Kotlin: Android
+* Python: Linux, macOS, Windows
+* Swift: iOS, macOS
+
+I created a simple "Hello World" example for each language to understand the basic requirements of each platform.
+
+By the way, OpenWrt turned out the most complex platform to create "Hello World" for, because my TP-Link TL-MR3020 r1 router is considered obsolete since 2018. I had to use the old 17.01.7 firmware, which took about three weeks.
+
+# Anchor language and limited language model
+
+For the whole month I was asking myself the same question: "Which language should I choose as a starting point to convert to other languages from?" Initial considerations were pointing me to C++ due to strong types. However, as soon as I found out Python has Type hints, I chose Python.
+
+Python is good because:
+* one can specify a type with Type hints
+* Python has portability across Linux, macOS, Windows out of the box
+* pip simplifies distribution of the language conversion instrument
+* Python does not require a separate compilation step, which speeds up development
+
+
+However, not every Python code will suite the language conversion instrument under development. Only the code that satisfies the constraints of the `Limited language model`.
+
+Limited language model is a subset of Python with various restrictions in both syntax and a set of available functions. Here is a glimpse of those restrictions, the image below depicts Python to C++ conversion result:

+
+# April plans
+
+I'm going to write game logic for "Memory" in Python and convert it to C++ by the instrument under development.
