Rob and Jason are joined by Alessandro Pignotti. They first talk about a linker project, a better assert for constexpr code. Then they talk about Cheerp, LeaningTech’s C++ WebAssembly compiler, how it differs from emscripten, Cheerp optimizations and some of LeaningTech’s other Cheerp products.
One of our readers recommended paying heed to the Espressif IoT Development Framework. He found an error in the project code and asked if the PVS-Studio static analyzer could find it. The analyzer can't detect this specific error so far, but it managed to spot many others. Based on this story and the errors found, we decided to write a classic article about checking an open source project. Enjoy exploring what IoT devices can do to shoot you in the foot.
Rob and Jason are joined by Corentin Jabot. They first talk about a Visual Studio blog post on performance improvements in the ‘inner build loop’, and a ray tracer built into CMake. Then they talk to Corentin about his work in the C++ ISO committee on the Library Evolution Working Group and his thoughts on what could and should make it into C++23.
Your language isn't broken, it's doing floating point math. Computers can only natively store integers, so they need some way of representing decimal numbers. This representation comes with some degree of inaccuracy. That's why, more often than not, .1 + .2 != .3.
We know that Stack Overflow is a daily part of a lot of developers’ lives. I’ve heard from multiple people that they come here daily (if not more often) to get answers to their questions. Sometimes the answer to a question about code comes as a chunk of code. And sometimes that code makes it into production applications because it answered the question perfectly.
