There is a typographical error in Francis Glassborow's "Homework Challenge 4" (C Vu 33.3, July 2021) that made it past the editing process. The third sentence in the fourth paragraph should read "It is professionals, white-collar workers ..." and not "... white-colour workers ..."
The ACCU committee is investigating methods and procedures that can be put in place in order to avoid this type of error in the future. In this instance, we have corrected the error in the online version of the article, and in the ePub and PDF versions of the magazine. Unfortunately, the printed copy of the magazine had already been mailed to members when the error was found.
ACCU sincerely apologizes for the error and any offence that it caused.
The July 2021 ACCU C Vu journal has been published and should arrive at members' addresses in the next few days. C Vu 33-3 and previous issues of C Vu can be accessed via the Journals menu (ACCU members only).
The June 2021 ACCU Overload journal has been published and should arrive at members' addresses in the next few days. Overload 163 and previous issues of Overload can be accessed via the Journals menu.
ACCU 'local' online events is pleased to welcome Richard Park who will be telling us about A Programming Language and Phil Nash who will fill in languages from B to C - and beyond - while presenting 'Polymorphism À La Carte'
The event will be hosted, virtually, on Remo. This will also give us the social and networking aspect of meet-ups that we miss from the in-person version.
When: Thursday, 20th May 2021, 19:00 start.
Duration: Around 2 hours.
Where: A link to the event will be sent to those who RSVP as attending nearer the time.
To attend: Please sign up on the ACCU London event page: https://www.meetup.com/ACCULondon/events/277980280

19:00 Intro and News
19:10 A Programming Language for Thinking about Algorithms - Richard Park
Being able to code isn't enough. You have to be able to reason about your algorithms if you want to get them right. Just like the symbolic notation of traditional mathematics allows you to think about your formulas, so too, a programming language inspired by traditional mathematical notation can aid your thinking about problems and the code used to solve them.
This session presents APL and its benefits for high-level development and comparison of algorithms, leading to an intuition about performance, for example in the context of memory access and amenability to GPU computing.
20:15 Polymorphism À La Carte - Phil Nash
If we've been using C++ family languages (including Java, C#, D etc) we may have a narrow idea of how polymorphism works. In this talk we'll present several different ways to do polymorphism, in a few different languages, along with their respective trade-offs, and conclude that, ideally, we'd have access to several approaches so we can pick the right one for the moment. Clojure does just that, coining the term Polymorphism À La Carte, and we'll hint at a C++ library that can do so, too. We'll do this in the context of the historical family tree of languages that C++ grew up in.
21:00 Talks end -- socialising in Remo
About the speakers:
Richard Park works for Dyalog, a modern APL implementor, teaching both novices and more experienced users about traditional and modern APL.
Phil Nash is the original author of the C++ test framework, Catch2, and composable command line parser, Clara. As Developer Advocate at JetBrains he's involved with CLion and ReSharper C++. He's also the organiser of C++ London and C++ on Sea, as well as co-host and producer of the cpp.chat podcast. More generally he's an advocate for good testing practices, TDD and using the type system and functional techniques to reduce complexity and increase correctness. He's previously worked in Finance and Mobile offers training and coaching in TDD for C++.
