Mocking C++

Image
By
This month’s ACCU London was at 7City to hear Ed Sykes tell us about a couple of C++ mocking frameworks, MockIt Now and HippoMock. Ed is a very relaxed, confident speaker and the code and demonstrations he used were simple, straight forward and easy to understand. I mostly came a long to meet Ed as he’s an excellent contributor to the ACCU and specifically the Mentored Developers projects.

Ed obviously hit a chord with the audience and there was plenty of interaction and question asking. There were even a few tangents that Ed handled brilliantly. It looks like both of these frameworks use quite a bit of compiler magic and function pointer repointing, along with macro magic to achieve in C++, what is easily achieved with reflection in the likes of Java and C#.

Following the short presentation there was a long discussion on the more general topic of mock objects. Even though I haven’t used C++ for a little while, this presentation was absolutely fascinating and I will definitely be using a mock framework on my next C++ project.

It's great to be back at the ACCU Conference 2025!

By
Last week I was back at the ACCU Conference in Bristol, for the first time since I gave an opening keynote in 2019 . In March 2020, COVID hit the UK and I got out of the habit of attending and speaking at conferences. Plus the ACCU Conference, and the organisation in general, took a big step back towards C++ and that hasn’t been relevant to me for nearly two decades. It’s taken until now, 2025 for me to want to talk again, and I was really pleased to be accepted for the ACCU Conference again. It was just a 20 minute session and I only attended for the day I was speaking. There was enough varied content for it to be interesting to me and I’m hoping to be back for the full conference next year. I really enjoyed attending and it was great to catch up with people I hadn’t seen for years. I felt re-engaged and particularly liked being asked if I’d been to nor(DEV):con . Learning to stop writing code (and why you won't miss it) Daisy Hollman I should have read the summary of the openin...

Write Your Own Load Balancer: A worked Example

By
I was out walking with a techie friend of mine I’d not seen for a while and he asked me if I’d written anything recently. I hadn’t, other than an article on data sharing a few months before and I realised I was missing it. Well, not the writing itself, but the end result. In the last few weeks, another friend of mine, John Cricket , has been setting weekly code challenges via linkedin and his new website, https://codingchallenges.fyi/ . They were all quite interesting, but one in particular on writing load balancers appealed, so I thought I’d kill two birds with one stone and write up a worked example. You’ll find my worked example below. The challenge itself is italics and voice is that of John Crickets. The Coding Challenge https://codingchallenges.fyi/challenges/challenge-load-balancer/ Write Your Own Load Balancer This challenge is to build your own application layer load balancer. A load balancer sits in front of a group of servers and routes client requests across all of the serv...

I, Robot

By
The Foundation series has been my go to for a good, enjoyable read over the last two years, so naturally I moved on to Asimov’s Robot series afterwards. However, the short stories in I, Robot were mostly a disappointment. They feel self indulgent, with too much philosophy and science, Asimov showing off, and not enough story. The most enjoyable moments come from the stories featuring Gregory Powell and Mike Donovan. Their banter and the relationship between them provide some much needed amusement and were easily the highlight of the book for me. However, it did give me food for thought for the current potential issues with the rapid development of AI at the moment, and the many concerns around safety. I wonder if all we need is: An AI may not injure a human being or, through inaction, allow a human being to come to harm. An AI must obey the orders given it by human beings except where such orders would conflict with the First Law. An AI must protect its own existence as long as such p...
