The last update to the schedule for Meeting C++ 2025

by Jens Weller

From the article:

With release of the static html schedule for the website everything is ready for Meeting C++ 2025!

For a few years now Meeting C++ offers two schedules: the live schedule is coming from the database, which allows us to make changes during the conference. The other schedule is part of the static website and just a single page powered by the C++ CMS from Meeting C++. Due to the 5th track this year I've just had one week before the conference the time to update the website with this now final program for the conference.

 

Celebrating C++’s 40th birthday at C++ Day in Italy

By Marco Arena | Oct 27, 2025 06:42 AM | Tags: community

This year marks C++'s 40th anniversary, and at C++ Day 2025 (a proper "wrap-up post" will follow in the next days) we couldn't let the occasion pass without a little celebration!

While there wasn't a cake, we gathered everyone to sing "Happy Birthday, C++":

 

 

Followed by a lively game that mixed 1980s pop culture, ISO C++ trivia, Bell Labs history, and more:

 

  

Over 160 people joined the event, with about 120 staying until the end to play and win some unique prizes: 1980s-style posters featuring movie quotes reimagined with a C++ twist:

 

And we had a winner!

 

 

Also we ran a raffle including all quiz participants:

 

 

The posters also decorated the venue all day long, giving it a warm, retro, and festive feel:

 

 

It was a small but heartfelt way to celebrate four decades of a language that continues to inspire and evolve.

 

Here's to the next 40 years of C++!

Looking at binary trees in C++

By Meeting C++ | Oct 24, 2025 08:22 AM | Tags: meetingcpp community

While preparing a talk for Meeting C++ 2025 I've started looking into binary trees. And got curious about a different design choice.

Looking at binary trees in C++

by Jens Weller

From the article:

I'm in the process of preparing a quick talk on trees in C++ for Meeting C++ 2025. In order to see what the web offers, I've searched exactly for this, "trees in C++".

This showed that most posts found by duckduckgo or google were about binary trees, and in particular the same or similar implementation of using raw pointers for the left/right elements in the tree. Including using new to allocate for the nodes, only some times the code also bothers with using delete. The basic node class looks like this:

Rainer Grimm passed last week

Sadly I have to inform you about Rainer Grimms passing last week. He was a great C++ author, trainer, speaker and friend. Heartfelt condolences to his family.

Rainer Grimms ALS Journey 31/31: the end

by Beatrix Grimm

From the article:

Dear readers, we are extremely sad to inform you that Rainer passed away on October 6, 2025, surrounded by his closest family. After suffering from life-threatening pneumonia, Rainer decided against further life-sustaining measures that would have severely restricted his life. He passed away peacefully, accompanied by his family.

You should use QPainterPath they said...

A blog entry about this years t-shirt at Meeting C++ 2025 and exploring QPainterPath for it.

You should use QPainterPath they said...

by Jens Weller

From the article:

This post is about what I learned while playing around with QPainterPath for this years t-shirt at Meeting C++ 2025 sponsored by Hudson River Trading.

One of the issues from last years t-shirt was when using drawText from QPainter, one does not really *draw* text in an svg exported. Instead you'll get the text and the font kinda embedded in an svg. What good is that in a vector graphic? This was a bit of a surprise when I ran into issues with this last year during printing. While this could be solved with the printing company picking a different font, it would have been also solved by using QPainterPath. At least this was the feedback from some of the Qt experts present onsite or online...

With Meeting C++ 2025 just being 5 weeks away, I share a call for sponsors with you.

Maybe your employer is interested in being present as a sponsor at this years Meeting C++ conference? Have you thought about the possibilty that you could have your employer sponsor Meeting C++ 2025?

Meeting C++ is offering online and onsite student and support tickets for this years conference!

Highlighting the student and support tickets for Meeting C++ 2025

by Jens Weller

From the article:

I'd like to point towards the programs for those that can't afford to pay for a ticket for Meeting C++ 2025: the programs for the student and support tickets.

And let me start with thanking those that enable these programs through their ticket buying: the attendees and sponsors of Meeting C++ 2025! With the schedule published, I'd like to highlight the student and support tickets for Meeting C++ 2025. For a few years now Meeting C++ has hosted programs to give students, underrepresented folks and those who can't afford a ticket access to the conference.

From the article:

The next Meeting C++ online job fair is planned for October 14th & 15th, also I'd like to talk about the onsite job fair plans for Meeting C++ 2025!

If you have open positions you should advertise them in the bi-weekly Meeting C++ Jobs Newsletter, which now also powers the candidate listing of Meeting C++ with 80+ international candidates at the moment.
