Multipath TCP extension for Nginx

Multipath TCP was a subject of my Master Thesis, so I'm going to write a few posts about different aspects of this useful extension for well known TCP protocol. In this post I only want to describe my extension for Nginx server.

Embedding files in C++20

I'm trying to follow proposals for new C++ standards. There is a lot of documents informing C++ enthusiasts about features which will make our code cleaner, more comprehensible, but sometimes we can see propositions of improvements which will let us to resign from external libraries in favour of standard ...

My favourite C++17 language features

In 2017 a new standard of C++ language has been released. Unlike C++14, C++17 has introduced a lot of new features. C++14 was rather a supplement for C++11 (ok, it has introduced some completely new features, but most were improvements of what we had known from C++11). C++17 brought a lot of new possibilities.

In this post I'm going to tell you about new things in C++17 which I like the most, because I found them useful in my newest projects.

Safe passwords

When I started using Internet regularly back in 2007 or so, I used to use same password everywhere. I was changing it periodically (but not so often). After some time (probably a year) I started using password managers. First one was KeePass. I had two pendrives: one with database, second ...

A year after switching to Colemak

About one year ago (in September 2016) I decided to try keyboard layout other than QWERTY. I wanted to learn touch typing and be able to still use QWERTY when needed. I had already heard a lot of good things about Dvorak that time, but I wanted to be able to still use QWERTY ocasionally and I thought that Dvorak is too different than QWERTY. At that time I was aware of Colemak existance. Colemak is advertised as easy to learn and ergonomic layout which increases typing speed (especially in English) and is quite similar to QWERTY. Colemak moves only 17 keys. So I decided to give it a chance.

I'd like to tell you something about training process, summarize my progress and tell you why using alternative layout is not so painful.

Renewed website

Through last few months nothing has happened here. Year 2015 was probably the worst if we talk about number of publications, which I have written. However they were the best articles I have ever written. Four of them has been translated to French by My articles has been linked on Twitter among other by biicode. One time my article was linked on

Fighting off memory leaks and errors (C++11)

Modern tools provided with C++11's standard library make fight with memory leaks and errors easier and more effective. Sometimes problems which are seemingly not dangerous might put an end to your application. We are going to learn how to find and avoid them.

Programming modular applications in C++ (Part 2)

In the latest part of Programming modular applications in C++ I have shown you some practical examples of modular applications. These applications probably work well with your dedicated plugins. Problems begin when you try to mix in plugins written by your users which have been compiled using different compilers (it might work) or even operating systems (it cannot work!).

Programming modular applications in C++ (Part 1)

In the Introduction to programming modular applications in C++ I described some simple examples. In this part I'm going to show you more sophisticated applications which also will use modules. Examples from this part will be object oriented and will present more professional approach to programming modular applications.

In this part I'll show you two examples. First would be a solution of task which I gave you at the end of last article. You were asked to write a calculator which can add numbers, subtract them and load modules with other operations. The second example I'm going to write for you will be simplified system shell (so-called command line).

Introduction to programming modular applications in C++

Nowadays nearly every application can be extended with many different types of add-ons or plugins. Thanks to them we can write new functions to our favourite applications without rebuilding them each time we want to extend or modify it. I'm going to tell you how to write modular application in C++.
