If you're in trouble and cannot find an answer to a question which goes beyond Stack Overflow...
If you have a not-so-usual solution for your problems but need to justify it to your boss...
If you like to think on your own rather than blindly follow "common wisdom" and "profound truth"...
...then 'No Bugs' Hare on Soft.ware might be the right place for you.

‘Speedy Gonzales’ Serializing (Re)Actors via Allocators

Quote: “Allocator-based serialization for (Re)Actors is extremely fast (for x64 – around tens of ms per 100MB of state)”
Another Quote: “Per-(Re)Actor allocators can be implemented without any changes within (Re)Actor itself (i.e. all the necessary changes can be confined to Infrastructure Code).”

Parallel STL for Newbies: Reduce and Independent Modifications

Quote: “with std::reduce() such code, while it compiles at least under MSVC, MAY occasionally provide wrong results”
Another Quote: “if you happen to need something beyond that – take a deep breath and allocate at least several months to understand how does parallelism really work under the hood.”

#ACCU2018. Day 2. Threads and Locks ARE a Dead End, Period!

As the Day 2 of ACCU2018 is over, here is my report about it. Kotlin ~= Java with a Better Syntax Keynote of Day 2 was about Kotlin (titled “Kotlin/Native – Embracing existing ecosystems”), delivered by Hadi Hariri. While the talk as such was pretty good, I wasn’t convinced that Kotlin is worth the trouble. My takeouts from […]

#ACCU2018 Day 1. From Gender Equality to (kinda-)Quantum Computing, with Threads and C++ copy/move in between

As #ACCU2018 is underway, and as I am here, it would be strange if I wouldn’t use the opportunity to tell about what I like (and don’t like ;-)) here. Diversity in Tech – What Can We Do? Gen Ashley was opening the conference with a keynote speech on “Diversity & Inclusivity in Tech”. Main point: […]

Using Parallel <algorithm> Without a Clue: 90x Performance Loss Instead of 8x Gain

Abstract: “I made an experiment which demonstrates Big Fat Dangers(tm) of implying that parallelization can be made as simple as just adding a policy parameter to your std:: call.”
Quote: “it is still necessary to understand what we’re doing”
