Thursday 13th September 2018: 6.17pm. Link shared: I'll be speaking at the C++ users group Dublin this coming Monday 17th September. Entire evening will be just me, 90 minutes, no other speakers. I just finished the slides for the talk just there, it shouldn't be too boring for folk hopefully. And it's the only talk I'll give in all of 2018, usually I speak twice a year at conferences, but this year has been unusually quiet for me.
Wednesday 7th June 2017: 8.24am. Link shared: My proposed Boost.Outcome library's review report: It was rejected after one of the lengthiest reviews in many years. Lots of good feedback on how it ought to look. #boostcpp #c++ #boost-outcome
Saturday 3rd June 2017: 9.45pm. The peer review of my proposed Boost.Outcome library ended yesterday after being extended to two weeks to allow more discussion. Some 732 emails were sent on the topic, one of the most vigorous debates on boost-dev in many years, and a very highly productive one I think despite that we did not find consensus.#boostcpp #c++ #boost-outcome
Monday 13th March 2017: 6.11pm. Link shared: One of those big ol personally momentus days today. In the wee small hours last night shivering in Clara's bedroom as I'd stayed there working on the laptop after putting her to bed and it got cold, I finally delivered my Outcome library to Boost peer review. That library has taken me two years of my free time to write, and a never ending long tail of incredibly boring minute detail over the past four months or so to actually deliver the thing.
Thursday 26th May 2016: 8.20am. Link shared: I'm not a natural C++ metaprogrammer, so it took me two mornings before work to come up with this of which I am quite proud:```#include <stdio.h>#include <string>template <class... Args> struct Foo {};template <class T, class... Args> struct Foo<T, Args...> { T v; Foo<Args...> rest;};template <class T> struct Foo<T> { T v; };namespace detail {template <size_t N, class T, class... Args> struct getFoo { constexpr auto operator()(const Foo<T, Args.
Friday 15th April 2016: 10.47pm. Employment is on pause from now until I present proposed Boost.AFIO v2 for the first time at the ACCU conference next week. I'm up in Bristol 2 room, Thursday at 11am! The distributed mutual exclusion file system algorithm I'm presenting is completed, the slides have proved to be a bit of a bear though, can't get the structure to where I'm happy with it.#boostafio #boostcpp #c++ #accu
Saturday 9th April 2016: 7.33am. Link shared: The ACCU conference is only ten days away! Proposed Boost.AFIO v2, which I'll be presenting for the first time at ACCU, has the functionality I'm presenting written as of yesterday but it most definitely is not working - as the final part I added all required itself to work, I spent two weeks writing code, only checking to see if it compiles, not if it works until now so I have a raft of debugging to do this weekend.
Monday 8th February 2016: 12.30am. Link shared: I reached a major milestone in the post peer review Boost.AFIO v2 rewrite today which has consumed most of my free time since November: it now has working Windows and POSIX AIO async file i/o backends with file open, close, clone, scatter-gather read/writes and truncate implemented, so a long, long way still from AFIO v1's comprehensive facilities but still an achievement. The POSIX AIO backend is 100% pure, and so therefore has awful performance because POSIX AIO has a terrible design, but it does work on FreeBSD and Linux without surprises and the storage profile probing yielded many interesting answers to long standing questions about concurrent file i/o atomicity which are now answering the many questions about this on Stackoverflow.
Wednesday 14th October 2015: 10.52am. CppCon videos are up, and here is mine on Racing the File System which is a beginner's level workshop on race free filing system techniques leading up to proposed Boost.AFIO, an asynchronous file and race free filesystem library for C++. As much as it's "beginner's level", it's more really "from first principles", so it gets into more interesting stuff by the end including the transactional key-value store I'd like to be standardised into the C++ runtime based on AFIO.
Wednesday 8th July 2015: 12.42pm. As lightweight C++ futures have matured it became painfully obvious that a ground up refactor of its design was required. The code base until very recently employed lots of "safe" undefined behaviour to save me writing code to deal with future to shared_future conversion etc, and of course making use of undefined behaviour always produces faster code, so specifically speaking what I was doing was to use reinterpret_cast to have the compiler not concern itself with whether the future the promise was talking to was really a future or a shared_future state.
