Join us for a C++ meetup, proudly organized by think-cell, on **Wednesday, November 13, 2024**. The event is for C++ engineers eager to explore the latest industry trends and techniques. It also offers a great networking opportunity before the **[Meeting C++](https://meetingcpp.com/2024/)** conference on **November 14** in Berlin. Connect with fellow engineers and industry experts over pizza and beer before the main event.

**Agenda**
18:30 Doors open, snacks & drinks
19:00 Meetup opening
19:10 “Express your expectations. A fast, compliant *JSON* pull parser for writing robust applications” by Jonathan Müller
20:00 “Think Parallel” by Bryce Adelstein Lelbach
20:50 End, pizza and beer, networking

**Talks**
**Think Parallel**
By default, we think sequentially. Parallelism and asynchrony are often seen as challenging and complex. Tools to be used sparingly and cautiously, and only by experts.
But we must shatter these assumptions, for today, we live in a parallel world. Almost every hardware platform is parallel, from the smallest embedded devices to the largest supercomputers.
We must change our mindset. Anyone who writes code has to think in parallel. Parallelism must become our default.
In this example-driven talk, we will journey into the world of parallelism. We'll look at four algorithms and data structures in depth, comparing and contrasting different implementation strategies and exploring how they will perform both sequentially and in parallel.
During this voyage, we'll uncover and discuss some foundational principles of parallelism, such as latency hiding, localizing communication, and efficiency vs performance tradeoffs. By the time we're done, you'll be thinking in parallel.
**Speaker - [Bryce Adelstein Lelbach](https://github.com/brycelelbach)**
Bryce Adelstein Lelbach has spent over a decade developing programming languages, compilers, and software libraries. He is a Principal Architect at NVIDIA, where he leads HPC programming language efforts and drives the technical roadmap for NVIDIA's HPC compilers and libraries. Bryce is passionate about C++ and is one of the leaders of the C++ community. He has served as chair of INCITS/PL22, the US standards committee for programming languages and the Standard C++ Library Evolution group. Bryce served as the program chair for the C++Now and CppCon conferences for many years. On the C++ Committee, he has personally worked on concurrency primitives, parallel algorithms, executors, and multidimensional arrays. He is one of the founding developers of the HPX parallel runtime system. Outside of work, Bryce is passionate about airplanes and watches.

**Express your expectations. A fast, compliant JSON pull parser for writing robust applications**
There are, by now, several well-established C++ JSON libraries. C++ developers can choose between DOM parsers, SAX parsers, and pull parsers. DOM parsers are by design slow and use a lot of memory, SAX parsers are clumsy to use, so pull parsers are the way to go. Our open-source JSON parser fills this gap between the existing parser libraries. It is a fully validating, fast, pull parser with O(1) memory usage. The key innovation lies in our API design. Unlike other parsers that solely validate JSON, ours enforces semantical constraints, requiring developers to define specific structures. This results in automatic error handling and simplifies code. You can also parse directly into your own data structures without any extra copies.
This talk showcases our JSON parser API in action, comparing it with established counterparts. Additionally, we demonstrate elegant generic programming C++ techniques, making it accessible to both beginners and intermediate developers.
**Speaker - [Jonathan Müller](https://www.jonathanmueller.dev/)**
Jonathan is a Software Engineer at think-cell. There, he is responsible for maintaining think-cell's core libraries, which include a custom range library, a fast and convenient JSON parser, and many other utilities and data structures to write elegant C++ code. Before working at think-cell, he wrote many useful open-source C++ libraries. He is also a member of the C++ standardization committee, where he serves as the assistant chair for std::ranges, and a frequent conference speaker.

**Venue**
The meetup will be held at **[Le Wagon](https://www.meetup.com/le-wagon-berlin-coding-bootcamp/?recSource=group_search&&recId=9a95fd15-1bad-4068-bc0c-f18849398c9f&&searchId=4422541f-743d-47b3-af66-59ac174a49ea)**, a vibrant and welcoming space perfect for our gathering. We would like to extend our gratitude to Le Wagon for their generous cooperation in hosting this event.
