The current Berlin status for Meeting C++ 2020

by Jens Weller

From the article:

With this post I'd like to give you the details for the onsite event in Berlin in November 2020.

First, let me say that unless there is a local lockdown, this is going to happen. I've been in Berlin at the beginning of the week, and had a meeting with the hotel. So this is the up to date information. And I assume for some of you its something to look forward to, to enjoy a real conference with actual people in 2020. The tickets for Berlin are available, and these include access to the online event.

Part 2: Upsetting Opinions about Static Analyzers

By Andrey Karpov | Oct 16, 2020 01:27 AM | Tags: volatile static code analysis pvs-studio false positives

By writing the article "Upsetting Opinions about Static Analyzers" we were supposed to get it off our chest and peacefully let it all go. However, the article unexpectedly triggered robust feedback. Unfortunately, the discussion went in the wrong direction, and now we will make a second attempt to explain our view of this situation.

Part 2: Upsetting Opinions about Static Analyzers

by Andrey karpov

From the article:

And started coming up with cases when it might be justified, which means that the PVS-Studio analyzer warning was a false-positive. Some speculations about the change in memory between two checks came into play which occurs due to:

  • running parallel threads;
  • signal/interrupt handlers;
  • the variable X is a reference to the element A[0];
  • hardware, such as performing DMA operations;
  • and so on.

After heated debate on the analyzer's inability to comprehend all cases, they left to cut down forest with axes. In other words, they found an excuse why they could still avoid using a static code analyzer in their work.

C++ Day 2020

November 28, 2020

 

In a nutshell

The C++ Day 2020 is an online-only event about C++ with live sessions and virtual tables for networking (based on Remo).

 

What can I find in the Virtual C++ Day 2020?

We are scheduling:

  • 8x50-min live sessions
  • virtual networking based on Remo

You can refer to the event page for more information.

 

How can I attend the virtual event?

The event will go live on November 28 from 9 AM CEST and will last for the entire day.

All the sessions will be hosted on our YouTube channel. However, only registered people can see session links in advance.

Virtual tables will be hosted on Remo, kindly made available by the Standard C++ Foundation. For invitation link and further details, you must register.
 

Who supports this event?

The event is totally organized by the Italian C++ Community and it is supported by the Standard C++ Foundation.

 

Do I need to register?

The C++ Day 2020 is totally free (as all the previous editions) but you must register to be invited to virtual tables and to receive session links in advance.

Direct link to (free) tickets here.

The basics.

C++ as a Second Language (Chrome University 2020)

by Chris Blume

Summary of the video:

A tour of C++ for experienced/advanced programmers coming from other languages (C/Java/JS/Python/Go/VHDL/etc). Chris Blume explains C++11 features, free functions, include & linkage, destructors & scope, RAII, pass-by-value / -reference, the standard library, and smart pointers...

Before we get metaclasses one day?

C++ Compile time conditional struct member variables

by Saleem Ahmad

From the article:

C++ has rich set of features to do compile time calculations and optimizations to generate a better code. In one of code segment I have very large data structure in which few member variables are not used based on compile time if constexpr condition, but these variables are logged in the log line...

Upsetting Opinions about Static Analyzers

By Andrey Karpov | Oct 12, 2020 06:39 AM | Tags: static code analysis static analyzer pvs-studio data-flow analysis code analysis

Static analysis tools have advanced far over the time they've been around. They no longer resemble the "linters" that were in active use 20 years ago. But some programmers still view them as extremely primitive tools. And that's very sad.

Upsetting Opinions about Static Analyzers

by Andrey Karpov

From the article:

Of course, any modern static analyzer tracks the changes of variables' values. If a variable doesn't change, a warning is issued. If it does, no warning is issued. To ensure that, analyzers rely on data stream analysis. And that's exactly how PVS-Studio works. Let's take a look at the following synthetic example.
