Thanks to the Chinese C++ experts who did this translation of Bjarne Stroustrup's latest History of Programming Languages paper! That's a massive job, and translations of technical papers are very rare in our field.

The ACCU is now putting together its program, and they want you to speak on C++. The ACCU conference has strong C++ tracks, though it is not a C++-only conference. If you have something to share, check out their
Call for Papers
by the ACCU
About the conference:
The ACCU 2022 conference will be from 2022-04-06 to 2022-04-09, with a pre-conference workshops on 2022-04-05.
The ACCU 2022 will be a hybrit event.
Historically, ACCU has a lot of C++ and C content, and is proud of that: ACCU is the foremost annual conference for people interested in C++ and C, at least in and around the UK. But it is not just a C++ and C conference, ACCU is about programming in whatever language people are using, with whatever tools and processes people are using: D, Chapel, Java, Kotlin, C#, F#, Groovy, Rust, Go, Python, Ruby, Lisp, to name just a few programming languages about which there have been sessions at ACCU conferences. Git, Mercurial, CMake, Meson, TDD, BDD, allthese tools and techniques have been the focus of sessions at ACCU. The ACCU Conference is looking for sessions that will be interesting to people who create software.
The ACCU Conference is put on by ACCU (https://accu.org), but is open to anyone who wishes to be there either as a presenter or an attender.The Call for Papers lasts for about 3 weeks and will close on Friday 5th November 2021 at 23:59:59 GMT.

Registration is now open for CppCon 2021, which starts on October 24 and will be held both in person and online. To whet your appetite for this year’s conference, we’re posting some upcoming talks that you will be able to attend this year. Here’s another CppCon future talk we hope you will enjoy – and register today for CppCon 2021 to attend in person, online, or both!
C++20’s ＜chrono＞ Calendars and Time Zones in MSVC
Thursday, October 28 • 10:30am - 11:30am
by Miya Natsuhara
Summary of the talk:
The ＜chrono＞ header has existed since C++11, but C++20 dramatically increased its capabilities. MSVC has completed this C++20 feature and this session will focus on the development of our implementation and Windows-specific considerations that we encountered. For instance, how do we know if a given point in time is during a leap second insertion? Where do we get the data for time zones? If you are excited by these new chrono features and want to support a Windows platform, come and learn about its developments and caveats for a Windows implementation!
We will also touch on how STL maintainers and our valued external contributors developed the new features collaboratively. If you’re interested in participating in our open-source repo by reporting issues, contributing to discussions, or submitting pull requests, we hope that hearing about an example of collaboration will encourage you to visit our repo in the future.

From Problem to Coroutine: Reducing I/O Latency
Wednesday, October 27 • 10:30am - 11:30am
by Cheinan Marks
Summary of the talk:
Coroutines are now officially part of the C++20 standard and one of their advertised uses is reducing I/O latency. Almost all of the literature on coroutines that I found illustrated either synchronous generators or described the nitty gritty details of coroutines using very simple usages. The best talk I found was Gor Nishanov's excellent talk from CppCon 2018, "Nanocoroutines to the Rescue!" (go watch it!) which solves a different problem than mine, but mostly illustrates the power of coroutines.
In this talk I want to approach coroutines from another direction. I will start with the problem, which almost all engineers face in some form, that of reducing I/O latency while searching and gathering data from a sequential file. Instead of going into the details of how the coroutines work, I will start with the naive synchronous solution and build up coroutines step by step to try and reduce latency, illustrating the pieces as they are added.
Finally I will compare this solution to an old-fashioned solution using threads and we'll see how the coroutines performance measures up and whether all the additional boilerplate needed is worth the additional trouble. I hope discussing the value of coroutines and future proposals for RAII and executors will spark a good discussion with the audience.

Dependent Names
by Rainer Grimm
From the articles:
A dependent name is essentially a name that depends on a template parameter. A dependent name can be a type, a non-type, or a template parameter. To express that a dependent name stands for a type or a template, you have to use the keywords typename or template...

Improved Null Pointer Dereference Detection in Visual Studio 2022 version 17.0 Preview 4
by Gabor Horvath
From the article:
The C++ static analysis team is committed to making your C++ coding experience as safe as possible. We are adding richer code safety checks and addressing high impact customer feedback bugs posted on the C++ Developer Community page. Thank you for engaging with us and giving us great feedback on the past releases and early previews leading to this point. Below is the detailed overview of a new experimental code analysis check that can detect null pointer dereference errors, along with a comparison to an existing check that has the same purpose...

We are actively developing the PVS-Studio static analysis tool towards detecting Safety and Security-related errors. To be more precise, we've expanded the coverage of the MISRA C:2012 and OWASP ASVS standards. We have supported the MISRA Compliance 2020 standard. One of the more extraordinary innovations is the Best Warnings display mode.
PVS-Studio 7.15: MISRA, CWE, OWASP, Unreal Engine
by Andrey Karpov
From the article:
We have introduced a new feature for the PVS-Studio plugin for Visual Studio. Now you can display the Best Warnings the analyzer issued for a project. In other words, these are the analyzer's most valuable warnings. They demonstrate the analyzer's capabilities for someone, who is just starting out with the analyzer. We call this feature Analyzer Best Warnings. PVS-Studio has always been grouping analyzer warnings by 3 certainty levels. We've been traditionally using these levels to prioritize showing the analysis results — all best warnings should be first-level warnings. For the new version of our analyzer, we have developed a more accurate mechanism to evaluate warnings. Now the mechanism uses many extra criteria in addition to levels — both static (the average diagnostic "value") and dynamic. The dynamic criteria are based on warnings the analyzer issues for a specific code base (for example, detection frequency).

Another keynote to look forward to on-stage in Aurora, CO, USA, and livestreamed to online attendees:
CppCon 2021 Keynote: Small Inspiration -- Michael Caisse
From the announcement:
We’ve previously announced keynotes by Bjarne Stroustrup, Herb Sutter, and Lisa Lippincott. This is the fourth of our six conference keynotes to be announced.
We’re happy to announce: Michael will be in Aurora live, in person to deliver a brand-new talk about inspiring and being inspired by the embedded world around us.
Michael Caisse started using C++ with embedded systems over 30 years ago. He continues to be passionate about combining his degree in Electrical Engineering with elegant software solutions and is always excited to share his discoveries with others.
Here is his talk description:
Less than 1% of microprocessors sold each year find their way into general purpose computers. Desktops, laptops, and servers of all sizes represent a very small fraction of the compute that surrounds us. We interact with a few of these systems but most go unnoticed. These invisible, unsung embedded devices offer lessons in engineering at all scales and can provide inspiration to seasoned practitioners and future technologists.
Join me as we learn from the embedded world and become inspired to inspire.
This talk is the Keynote talk for the Embedded Track.
