Rob and Jason are joined by Matt Butler to discuss his perspective on the ISO Cologne meeting and Secure Coding. Matthew Butler is a security researcher who has been using C++ professionally since 1990. He has spent the past three decades as a systems architect and software engineer developing systems for network security, law enforcement and national defense. He primarily works in signals intelligence and security on platforms ranging from embedded micro-controllers to FPGAs to large-scale, real-time platforms. He is on the staff of both CppCon and C++Now as well as a member of the C++ Standards Committee. He spends most of his time in EWG, SG12 (Undefined Behavior and Vulnerabilities), SG14 (Low Latency) and, now, SG21 (Contracts). He is also a member of WG23 (Programming Language Vulnerabilities). He prefers the role of predator when dealing with hackers and lives in the Rocky Mountains with his wife and daughter. News What happened to C++20 Contracts?

Rob and Jason are joined by Clare Macrae to discuss Approval Tests and how they can be used to quickly test legacy C++ code. Clare is an independent consultant, helping teams streamline their work with legacy and hard-to-test C++ and Qt code. She has worked in software development for over 30 years, and in C++ for 20 years. Since 2017, she has used her spare time to work remotely with Llewellyn Falco on ApprovalTests.cpp, to radically simplify testing of legacy code. She has enjoyed this so much that she recently went independent, to focus even more on helping others to work more easily with legacy code.      Clare was until recently a Principal Scientific Software Engineer at Cambridge Crystallographic Data Centre. She is the original author of their popular 3D crystal structure visualisation program Mercury.

Rob and Jason are joined by Botond Ballo and Tom Honermann to discuss what features were added and removed from the C++20 draft paper at the ISO meeting in Cologne. Botond Ballo is a software engineer at Mozilla, where he has been working on the Firefox web browser's rendering engine for 6 years. He's been attending C++ standards meetings for about the same time, and blogging about them to keep the C++ user community informed about standardization progress. In the committee, his interests include general language evolution, reflection, and tooling. Botond likes to hack on IDEs and other developer tools in his spare time. Offline, you might spot him climbing rocks or reading fantasy novels. Tom Honermann is a software engineer at Synopsys where he has been working on the Coverity static analyzer for the past 8 years. His first C++ standard committee meeting was Lenexa in 2015. He currently chairs the SG16 text and Unicode study group and participates in the SG2 modules, SG13 HMI/IO, and SG15 tooling study groups. His contributions to C++20 include the new char8_t builtin type. A C++ minion with 20 years professional experience. Husband and father of two awesome boys.

Rob and Jason are joined by Tyler Ang-Wanek to discuss leveraging C++ in an ElectronJS app like GitKraken. Tyler Ang-Wanek has been developing software professionally for the past 3.5 years. He works as a senior developer at Axosoft, on the GitKraken team. His work primarily shifts among developing native node modules for use in GitKraken, architectural work for code and APIs around GitKraken, and developing new features for GitKraken. He is the creator of the node module Node Sentinel File Watcher (NSFW), a native file watcher written for GitKraken that has made its way into Atom and VSCode. One of his major accomplishments includes taking leadership of the open source native node module NodeGit. After much hard work on the NodeGit repo and within the community, Tyler joined the leadership group for LibGit2.
