CppCon, The C++ Conference

A build system should do more than compile code. It should help developers manage dependencies, understand build performance, and maintain software across different platforms without having to micromanage every underlying detail themselves. At #CppCon 2026, Kitware's Bill Hoffman discussed how CMake continues to address these challenges as software projects grow more complex. By capturing build requirements in CMake's target model, developers can reduce duplicated configuration across projects. CMake's instrumentation capabilities also provide insight into where time is spent during builds, helping teams identify areas for improvement. In his latest blog, Bill shares practical examples of how developers can use CMake's capabilities to improve their existing workflows, along with lessons from 26 years of CMake development.

Fantastic time at CppCon2026 conveying the message that becoming a Boost contributor and maintainer is a mutually beneficial interaction, and that it is much easier than what people assume. Great libraries written by tremendously smart people could not survive the passing decades without the contributions of many other hands. And there is pride and worth in writing a line of code that ends up on every phone on earth and even on the International Space Station 🚀 The best knowledge is what we build together 🤗

CppCon, The C++ Conference Nice to be there and help :) 

Here is a writeup of my talk at cppcon this year: https://lnkd.in/ewCPgMGm.

Remembering Rainer Grimm. Today one year ago Rainer Grimm died, he was a true titan of the C++ world. His writings and speaking was a big contribution to our community! https://lnkd.in/evQ35ENh #cpp #cplusplus

#cpp #cplusplus #RainerGrimm #inmemoriam As a teenager, I used to take the public transportation home in front of a large school. On the building's pediment, one day after another, I used to read the then-enigmatic Latin inscription by Virgil: 𝐋𝐀𝐁𝐎𝐑 𝐎𝐌𝐍𝐈𝐀 𝐕𝐈𝐍𝐂𝐈𝐓 𝐈𝐌𝐏𝐑𝐎𝐁𝐔𝐒. I read the inscription, over and over, unable to decipher its full meaning. Years later, having seriously studied Latin, I understood the meaning of this Virgil's teaching, expressed in his 𝐺𝑒𝑜𝑟𝑔𝑖𝑐𝑠: 𝐇𝐀𝐑𝐃 𝐖𝐎𝐑𝐊 𝐂𝐎𝐍𝐐𝐔𝐄𝐑𝐒 𝐀𝐋𝐋 𝐓𝐇𝐈𝐍𝐆𝐒. With that classical strength and powerful synthesis that characterized the Romans. At that time, nothing would have led me to imagine that, decades later, I would have the honor of meeting and working with a colleague in my professional life as a Software Engineer, 𝐚 𝐦𝐚𝐧 𝐰𝐡𝐨 𝐰𝐚𝐬 𝐭𝐡𝐞 𝐥𝐢𝐯𝐢𝐧𝐠 𝐞𝐦𝐛𝐨𝐝𝐢𝐦𝐞𝐧𝐭 𝐨𝐟 𝐭𝐡𝐢𝐬 𝐕𝐢𝐫𝐠𝐢𝐥𝐢𝐚𝐧 𝐭𝐞𝐚𝐜𝐡𝐢𝐧𝐠: 𝐑𝐀𝐈𝐍𝐄𝐑 𝐆𝐑𝐈𝐌𝐌. I began my exchange with Rainer on this platform a few years ago, given our shared dedication to software development and engineering in C++. I witnessed the onset of his illness, ALS, and, to my admiration, 𝐡𝐢𝐬 𝐭𝐢𝐫𝐞𝐥𝐞𝐬𝐬, 𝐮𝐧𝐰𝐚𝐯𝐞𝐫𝐢𝐧𝐠 𝐟𝐢𝐠𝐡𝐭𝐢𝐧𝐠 𝐬𝐩𝐢𝐫𝐢𝐭. For that reason, I began calling him 𝐅𝐢𝐠𝐡𝐭𝐞𝐫 𝐆𝐫𝐢𝐦𝐦, changing his name from "Rainer" to "Fighter", impressed by 𝐡𝐢𝐬 𝐝𝐞𝐝𝐢𝐜𝐚𝐭𝐢𝐨𝐧 𝐭𝐨 𝐰𝐨𝐫𝐤, 𝐝𝐞𝐬𝐩𝐢𝐭𝐞 𝐭𝐡𝐞 𝐠𝐫𝐨𝐰𝐢𝐧𝐠 𝐝𝐢𝐟𝐟𝐢𝐜𝐮𝐥𝐭𝐢𝐞𝐬 𝐨𝐟 𝐭𝐡𝐞 𝐝𝐢𝐬𝐞𝐚𝐬𝐞. My teenage experience, with the aforementioned phrase, flashed before my eyes as soon as 𝐈 𝐬𝐚𝐰 𝐑𝐚𝐢𝐧𝐞𝐫'𝐬 𝐮𝐧𝐩𝐚𝐫𝐚𝐥𝐥𝐞𝐥𝐞𝐝 𝐭𝐞𝐧𝐚𝐜𝐢𝐭𝐲. During that short time, I had the honor of being invited by Rainer to start working with him on a new C++26 book, which, unfortunately, could not be advanced due to the untimely progress of his illness, which 𝐞𝐧𝐝𝐞𝐝 𝐡𝐢𝐬 𝐥𝐢𝐟𝐞 𝐨𝐧 𝐎𝐜𝐭𝐨𝐛𝐞𝐫 𝟔𝐭𝐡, 𝟐𝟎𝟐𝟓.

On October 6, it was one year since Rainer Grimm passed away. His family has decided to keep his Modernes C++ blog going, and I am honored to be one of the authors who will write there. I met Rainer at a few conferences, including CppCon, and we talked over lunches and dinners. He was a great trainer, and over the years he sent a few of his clients to me. That is also how I came to work with his wife, Beatrix, who handled all the logistics for those workshops. Outside of C++, he coached runners at TV Rottenburg for more than 15 years and took several of them to the German championships. He was a great engineer, a great person, and an inspiration to many of us. It is so unfair what ALS did to him, and I really miss him. Marius, Beatrix, thank you for keeping his blog going. #cpp #cplusplus #ModernCpp

Yesterday marked one year since my dad, Rainer Grimm, passed away. I don't post on LinkedIn usually, but this one matters to me. Since we don't have access to the official Modernes C++ GmbH LinkedIn yet, I'm sharing it here: For those of you who don't know: My dad was one of the best-known voices in the C++ community and founder of the Modernes C++ Blog. C++ is a programming language that runs much of the worlds critical software, from cars and planes to browsers and financial systems. For years, he shared his knowledge through his blog, books, mentoring programs, trainings and keynotes all over the world. In times of AI, when every answer seems to be just a prompt away, you'd expect a blog like his to lose relevance. But his articles are still read by developers around the globe every day, and AI tools cite and link to them. Free, high-quality knowledge still needs a place to live. So after a lot of reflection, we decided to continue his blog. To confirm our decision, Pablo Esteban Camacho, who had started working with my dad on a C++26 book, shared a moving tribute to Rainer yesterday. We as a family didn't even know about it until it appeared. His post and the many reactions to it showed us that we made the right decision: Continuing his work is the best way to honor his legacy. To ensure quality, the blog will be written by a collective of his longtime friends and colleagues, all of them leading experts in the field: Klaus Iglberger, author of C++ Software Design, who starts next week with the first series Slobodan Dmitrovic, author of Modern C++ for Absolute Beginners Mateusz Pusz, ISO C++ committee member and creator of the mp-units library Ivan Čukić, author of Functional Programming in C++ Jens Weller, founder of the Meeting C++ conference For now, the blog will look exactly as it always has. To some, the design may seem old-fashioned, but it works, and it's what readers know. The content is what matters. Writing authentic articles at the forefront of C++ takes deep expertise and a lot of time. That's why were also open to new authors.

Today, we published a short post about what comes next: https://lnkd.in/eN-4sczN Thanks for caring and sharing, Marius #cpp #cplusplus #ModernCpp #SoftwareEngineering #Programming
