Trip report: C++ Siberia 2020

by Timur Doumler

In 2019, I had a very busy conference year. I had just become self-employed, which meant I did not have to ask anyone’s permission anymore to go to a C++ conference. And because conferences are fun, I decided to go to all of them. Well, not all of them, but I ended up speaking at quite a few that year: CppOnSea (Folkestone), ACCU (Bristol), using std::cpp (Madrid), 4Developers (Warsaw), C++Now (Aspen), CoreC++ (Tel Aviv), C++Russia (both of them – Moscow & St. Petersburg), CppCon (Denver), ACCU Autumn (Belfast), MeetingC++ (Berlin), and finally CoreHard (Minsk). The latter one was particularly memorable because it was the first time a C++ conference invited me to deliver the opening keynote (and it was an amazing experience – thank you!)...

Qt, range-based for loops and structured bindings

by Ivan Čukić

Qt has a long history. The first stable version was released before the first version of C++ was standardized and long before the different C++ compiler vendors started shipping usable implementations of the C++ standard library. Because of this, Qt often followed (and still follows) some design idioms that feel unnatural to the usual C++ developer.

This can have some downsides for the Qt ecosystem. The evolution of the C++ programming language which sped up quite a bit in the last decade often brings improvements which don’t fit well with the Qt philosophy. In this blog, I offer some ways to work with this...

Online Live Trainings with Train IT

by Mateusz Pusz

Traditional workshops are so-called "Closed Trainings". They are requested by a specific company, are delivered at its premises, and are provided only for its engineers, which means that they are closed to external participants.

On the other hand, "Open Trainings" are open to everyone but are harder to organize, thus provided less often. Additionally, they require participants to travel to a distant place of training, which besides additional time needed for it, also adds travel and accommodation costs to the training's registration fee.

Open Online Live Training joins the best parts of both cases. Read more...

Trip report: C++ Siberia 2020

by Timur Doumler

This conference took place just after the C++20 committee finished work on C++20 at the committee meeting in Prague, and just before all the other conferences got cancelled or postponed due to the covid-19 outbreak.

I gave the opening keynote, entitled "How C++20 changes the way we write code". It was a really great event, and I will remember it forever as it was my last trip before I started self-isolating.

How to Extract Words among Spaces in a C++ String

by Jonathan Boccara

We’ve already seen how to split a string into words with a delimiter, but there is another use case that is pretty close, and that doesn’t have the same implementation: extracting words that are among spaces in a string...

C++20: Thread Synchronization with Coroutines

by Rainer Grimm

It's a typical requirement for thread management to synchronize them. One thread prepares, in this case, a work-package another thread is waiting for...

I Accidentaly Wrote A Compile-Time Executable State Machine

by Philippe M. Groarke

Yes, you read that title right. While working on a new way to create finite state machines (fsm), I inadvertently designed a state machine you can execute at compile-time. With branching and everything. Today, allow me to pull you down my rabbit hole. It’s always nicer with company down here.

Let’s go, Alice!
