Hi, I'm Tomasz

Background There’s git which is a CLI tool implementing git SCM which we all know and love. Additionally, there’s libgit2 which is a reference implementation of git “standard”/“protocol”. The focus of it, is primarily to be used within applications that wish to integrate with git repositories and provide programmatic access to git facilities. Usually, languages like Python or Go use libgit2 under the hood to implement git bindings. This is the case with e.

In this post I’m gonna discuss how to generate SSL certificates for services hosted within your home network. This can be anything, your plex or jellyfin instance or any development infrastructure you might be hosting locally. Keep on reading if you’re tired of HTTP and “untrusted website” warnings from your browser. The plan I’m gonna use navidrome as an example for the purpose of this post. It’s a music player typically running on port 4533.

Recently I’ve converted one of my old PCs into a Proxmox server. In case you don’t know, Proxmox is essentially a virtual machines management environment. I didn’t really know if I’ll find it useful, just wanted to experiment a bit and maybe learn about terraform. Since then, I’m finding my virtual machines server quite useful. I can run my own small kubernetes cluster (k3s), docker registry, VPN gateway… all sorts of things.

I’m sure that we all know about the = delete keyword introduced in c++11 and its application to class member functions. I’m not sure though if everyone knows that = delete can be applied to free standing functions as well. Free standing functions application Main reason to have this feature is to limit the number of overloads and narrow down implicit conversion. std::cref and std::ref are a good example. cppreference for std::ref lists several overloads.

This post is part of a WebAssembly series focused on WASM and C++. The goal is to gain a thorough understanding of how WebAssembly works, how to use it as a compilation target for C++ code and hopefully have fun along the way. So, stick with me for this exciting journey. Recap So far, in this series, we’ve learned what WASM is, how to execute it in JavaScript engines (like browsers or node.

Recently, while working with a glue code integrating low level C APIs in C++ I stumbled upon a problem where I needed to map enum values to types (and vice-versa). Problem definition Imagine you’ve got a factory function: 1 2 3 4 5 6 7 8 9 10 11 12 enum class FactoryTypes { TypeA, TypeB, TypeC, }; struct NonCovariantTypeA {}; struct NonCovariantTypeB {}; struct NonCovariantTypeC {}; // TODO what to return here?

In this post I’m gonna implement a simple type list along with a set of basic operations that can be performed on it. Tuples? Isn’t it just a tuple? Not really, it’s something simpler than that. Tuple is a set of values of arbitrary types. Tuples are immutable as well (there’s std::tuple_cat with which operations like append and prepend could be implemented but this will result with a new instance of tuple with extended set of contents).
