Ben Deane - CppNorth, The Canadian C++ Conference "How to Use std::chrono for Calendrical Calculations in C++" Please Like, Follow, & Share: CppNorth, The Canadian C++ Conference Our job as programmers is to solve real-world problems with appropriate abstractions. The real world is messy, and few things are messier than dealing with calendars. It has been claimed -- without too much exaggeration -- that most mathematical progress before the 1600s was driven by trying to figure out when Easter falls. This talk combines C++, history, and the process of finding abstractions for this interesting and simplification-resistant problem. Attendees will learn plenty about the proper usage of std::chrono constructs, gain an insight into why calendars are so complex and how to find the right ways to express things clearly, and encounter a plethora of historical goodies along the way. If you need a break from thinking about the (somewhat self-imposed) problems of cutting-edge C++, this is the talk for you: there are only real-world complications here. I've been down this rabbit-hole for months; join me for an exploration of what I've found. --- Ben Deane Ben has been programming in C++ for this whole millennium. He spent just over 20 years in the games industry working for companies like EA and Blizzard; many of the games he worked on used to be fondly remembered but now he’s accepted that they are probably mostly forgotten. After getting more interested in modern C++, in the teens he started giving internal company talks and then talks at various conferences, spreading ideas about types, algorithms and declarative and functional techniques. In 2018 he left the games industry and worked in finance for a short spell, writing high-frequency trading platforms using the most modern C++ that compilers could support. Now he is a Principal Engineer at Intel where he puts monads inside your CPU.

As seen in the latest Computerphile video (https://lnkd.in/gTrzxJsq) .. An example of *pattern matching* in Rust (include use of the unbound variable) ... a facility that would look very good in Delphi and fpc. 😎

Did you ever wonder about a concrete use-case for the code in the picture? Today I started a mini series of C++ related articles with practical examples of some C++ features. In the first article you can read about my personal experienced real-world use case example for 𝐫𝐞𝐟-𝐪𝐮𝐚𝐥𝐢𝐟𝐢𝐞𝐝 𝐦𝐞𝐭𝐡𝐨𝐝 𝐨𝐯𝐞𝐫𝐥𝐨𝐚𝐝𝐬 where the whole object is moved out of its origin class instance.

As I am checking out C++26 features, I am excited on how much scientific code could be rewritten with tools coming directly from C++ such as "<linalg>: A free function linear algebra interface based on the BLAS" 🤗 https://lnkd.in/eNWDhTm2

CppCon, The C++ Conference 2023, Lightning Talk Jefferson Carpenter: "Un-Undefining Undefined Behavior in C++" Please Like, Follow, & Share: CppCon, The C++ Conference youtu.be/S49fKs0Bv1Q Interpreting the C++ abstract machine in the context of the real machine that it runs on. If your program contains UB, the compiler is allowed to emit any code whatsoever, and may optimize out any code paths leading to UB. But what if you made it so the compiler had no way to tell that the behavior was undefined? Then it would have to generate code such that, if the behavior was defined, the program would run correctly. Then you can write all the UB you want! In this undefined talk, I give a couple examples of UUB (un-undefined behavior). --- Jefferson Carpenter I spent my early life as a baby, but soon grew into a child. By college I had already graduated from high school, and now I'm extant.

Today's SO - tl;dr: don't use aliases, just make them functions. When writing dynamic code, timing (of interpolation) is everything. Bash stole this person's $1 intended as an AWK variable, resulting in broken code. https://lnkd.in/eRxNB6FH

🐍 Counting the Good Nodes in a Binary Tree. I finally fixed my audio issues! This solution is a clean recursion with a single function. I had to tackle some deadly typos this round, and got a good lesson why max variables should always start at negative infinity. 🕣 🔗 How do you handle linked list problems❓ https://lnkd.in/d7t-3ed6

Two things I like the most about C++ are expressiveness and compile-time computation. This year at the Embedded Online Conference, I will demonstrate how to use constexpr and other C++ features to build a highly expressive signal generator that does all the computation in compile time.
