With speakers and workshops now announced, all our ticket types are now open. This year sees a few changes, so let's take a quick tour.
Embedded Winter: Raspberry Pi 4B -- Richard Thomson
Utah C++ Programmers has released a new video.
Embedded Winter: Raspberry Pi 4B
by Richard Thomson
From the video description:
This Winter, we'll be hunkered down with embedded programming with C/C++ and some popular single board computer platforms popular in the 'maker' community.
This month, Richard Thomson will conclude with an introduction to the Raspberry Pi 4. Unlike the microcontrollers we've looked at so far, the Raspberry Pi is a complete linux computer system, with a local filesystem on an SD card, ample RAM, ethernet networking, USB ports for a keyboard and mouse and HDMI video. The Raspberry Pi foundation maintains a linux distribution tailored for the Raspberry Pi hardware.
In this presentation, we'll look at:
What are the on-board resources of the Raspberry Pi?
How do we access hardware resources under linux?
Execution and Static Analysis Support for MSVC on Compiler Explorer--Sy Brand
Will you try it?
Execution and Static Analysis Support for MSVC on Compiler Explorer
by Sy Brand
From the article:
Compiler Explorer is a popular resource for visualizing the assembly output of various compilers, trying out different compiler versions and flags, and testing many popular libraries.
We’re pleased to announce that, as of today, code execution and static analysis are now available for MSVC on Compiler Explorer. Execution on CE has been one of our highest voted tickets on Developer Community, so we hope many of you will find it useful. The static analysis tool provided is the same as offered in GitHub Actions and in the IDE as background code analysis...
More about Dynamic and Static Polymorphism--Rainer Grimm
The series continue.
More about Dynamic and Static Polymorphism
by Rainer Grimm
From the article:
In my last post "Dynamic and Static Polymorphism", I introduced dynamic polymorphism. Today, I continue with static polymorphism and present are very interesting idiom in C++: curiously recurring template pattern (CRTP).
Zero-cost exceptions aren’t actually zero cost--Raymond Chen
The devil is in the details.
Zero-cost exceptions aren’t actually zero cost
by Raymond Chen
From the article:
There are two common models for exception handling in C++. One is by updating some program state whenever there is a change to the list of things that need to be done when an exception occurs, say, because a new exception handler is in scope or has exited scope, or to add or remove a destructor from the list of things to execute during unwinding. Another model is to use metadata to describe what to do if an exception occurs. There is no explicit management of the state changes at runtime; instead, the exception machinery infers the state by looking at the program counter and consulting the metadata...

WinReg: Simplify Windows Registry Programming in C++ -- Giovanni Dicanio
Windows Registry programming using the native C API is cumbersome and bug-prone. Fortunately, you can simplify that using a modern C++ library like WinReg.
Simplifying Windows Registry Programming with the C++ WinReg Library
