  • One example for self documenting code is typing. If you use a language which enforces (or at least allows, as in Python 3.8+) strong typing and you use types pro actively, this is better than documentation, because it can be read and worked with by the compiler or interpreter. In contrast to documenting types, the compiler (or interpreter) will enforce that code meaning and type specification will not diverge. This includes explicitly marking parameters/arguments and return types as optional if they are.

    I think no reasonable software developer should work without enforced type safety unless working with pure assembler languages. Any (higher) language which does not allow enforcing strong typing is terrible.


  • I have worked on larger older projects. The more comments you have, the larger the chance that code and comment diverge. Often, code is being changed/adapted/fixed, but the comments are not. If you read the comments then, your understanding of what the code does or should do gets wrong, leading you on a wrong path. This is why I prefer to have rather less comments. Most of the code is self a explanatory, if you properly name your variables, functions and whatever else you are working with.













  • Netguard is a FOSS Android app which kinda works like a firewall. You can allow/block network access on a per-application basis. You can limit access e.g. on WiFi or on mobile etc. It also supports blocklists, supplementing your ad blocker.

    To the Android OS, Netguard acts as if it were a VPN.

    Limitations:

    • if you want to filter Android system services, you will break things. You will need to spend some time to do it right.
    • Chaining it to another VPN is only possible via SOCKS proxy
    • if you want to route some app’s traffic via VPN and others not, I think that is not possible. You could, however, manually turn off an app’s internet connection before disconnecting the VPN, if that is not too error-prone for you.

    The app is very stable, I have been using it for about 5 years without problems. For most use cases it is fire-and-forget, i.e. I rarely open the app any more.
