CopperSpice: What Do You Do When Your Codebase Is Old Enough To Vote?

New video on the CopperSpice YouTube Channel:

What do you do when your codebase is old enough to vote?

by Barbara Geller and Ansel Sermersheim

About the video:

This video explains our perspective on the process of modernizing an old codebase. We discuss what a codebase is, what considerations you should keep in mind during the migration, and strategies to use during the migration process. We also look at which version of the C++ standard to target and why refactoring may not be a viable direction.

C++ Annotated: June - September 2018

by Anastasia Kazakova

From the article:

... a hot C++ conference season kicked off again with CppCon. Pacific++, C++ CoreHard, Meeting C++, ADC, code::dive, and the C++ Committee meeting in San Diego, California, are coming up later this year...

... Today we are starting a new section in our regular C++ Annotated. In each issue, we will cover a selection of C++ proposals and initiatives you definitely should learn about while developing in C++. This time we unveil static exceptions, constexpr new, and lifetime checks. See details below...

PVS-Studio 6.26 Released

This new release included many interesting improvements related to analysis of C and C++ code, about which we'd like to tell our users.

PVS-Studio 6.26 Released

by Andrey Karpov

From the article:

A developer believes that this is a bug in the compiler. Nevertheless, it is the author of the code who is wrong. The function does not work correctly due to the fact that undefined behavior occurs in it. The compiler follows that in the r variable a certain sum is calculated. Overflow of the r variable must not happen. Otherwise, it is undefined behavior, which doesn't have to be considered or taken into account by a compiler. So, the compiler thinks that since the value of r variable after ending the loop cannot be negative, then r & 0x7fffffff operation is not needed to reset the sigh bit and the compiler just returns the value of r variable from the function.


Milestone | New Home | Trip Reports—Jon Kalb

The conclusion of this year cppcon.

Milestone | New Home | Trip Reports

by Jon Kalb

From the article:

At the formal closing of CppCon 2018, we took a moment to consider how far we’ve come in the first five years of the conference. Those years have seen us grow in so many ways. Since our first conference, we’ve added classes, field trips, author signings, exhibitor tables and booths, Tool Time, and the SG14 co-located ISO meeting. The number of main program sessions has grown by about fifty percent to almost one hundred fifty.  The number of Open Content sessions has doubled to about two dozen. The number of conference days (including classes)  has doubled from four and a half to nine and the number of attendees has doubled from about six hundred to over twelve hundred.

Trip report - CppCon 2018

by Jean Guegant

From the article:

New year, new conference! This time, my employer, King, helped me to organize a first pilgrimage to CppCon for me and another colleague. You cannot fathom how enthusiastic I was to finally making it there! Although I might be a bit late on the "trip-report-race", I think that it is still worth to relate my overall experience of the event and then move onto a list of recommended talks you should watch-out on Youtube...
