Exploring how much number conversions from string cost you and how caching helps

What do number conversions cost?

by Jens Weller

From the article:

And so the devil said: "what if there is an easier design AND implementation?"

In the last two blog posts I've been exploring some of the ways to implement a certain type that has a string_view and holds a conversion to a type in a variant or any. And my last blog post touched on conversions. And that made me wonder, what if I did not have a cache in the type for conversions? The memory foot print would be much smaller, and implementation could be simple to convert in a toType function on demand. This then would essentially be a type that holds a string_view, but offers ways to convert this view to a type. Adding a cache to hold the converted value is in this case not necessary, as this is done on demand.

Like every year, Meeting C++ is also offering a set of free tickets for students and those that are in need of a little support!

With the schedule published, I'd like to highlight the student and support tickets for Meeting C++ 2022.

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. This is supported through the ticket sales and some times sponsorships.

A post on conditional breakpoints, including two surveys about their usage.

About conditional brealkpoits

by Jens Weller

From the article:

A few weeks ago someone asked me for advice on finding a specific bug in a larger C++ code base...

I don't remember much of the details, but one of the challenges was that at least some of the code based used public members, and in order to find the bug a change in these members is what they wanted to understand. Adding out put statements into a setter function wasn't possible, as the code did not have those. My suggestion was using a conditional breakpoint. And it also made me curious, if and how they're used with in our community.

Since yesterday its possible to have a first look at the program of Meeting C++ 2022

A first view on the talks and speakers of Meeting C++ 2022

by Jens Weller

From the article:

I'm excited to release this update for Meeting C++ 2022: the talks and speakers for this years conference!

As you can see in the talk listing, this is still an ongoing process, getting the speaker pictures from the new speakers for this year will still take a while. Creating the schedule will also take a few weeks, as of now Tracks A and B are planned on site, with Tracks C and D being part of the online part.
