I think I'll host a Zoom tomorrow to present the Safe C++ stuff I've been working on. I need to get informed people up to speed with what I have so there can be a discussion on some of the finer, unresolved points about integrating safety into C++. How does 10am EST sound?

RETWEET if you are cis and know that #CisIsNotASlur.

@code_report @ben_deane @phil_nash @tristanbrindle @odinthenerd I gave a talk back in 2018 with a similar definition: youtu.be/_x1EvX-q3QU?t=…

C++ Twitter? Have you seen in a talk or given a talk with the following code example? ⬇️ I swear I have seen this 3 or 4 times in different talks but can't find any (after checking ~10). @ben_deane @phil_nash @tristanbrindle @odinthenerd godbolt.org/z/saGWh8P5r

@TaeKahn @code_report I don't follow, what did you mean to write then? Note that omitting the & operator will still take the function's address.

@toby_allsopp @code_report Yes, it was a typo. Taking the address isn't required here. Its rare that i'm willing to delete a tweet to fix a typo.

Typing out this C++ code is heartbreaking. The fact that std::plus, std::minus, etc work but std::max & std::min fail and need to be wrapped in a lambda is 💔 And if C++ algorithms were well-named/consistent this would be std::scan_copy and there would also be a std::scan 💔

@TaeKahn @code_report Not sure if you're aware, but it is not permitted to take the address of standard library functions (with a few exceptions). See #Addressing_restriction" target="_blank" rel="nofollow noopener">en.cppreference.com/w/cpp/language…

@code_report std::inclusive_scan(v.cbegin(), v.cend(), v.begin(), &std::max<int>); ......just because you've never read the standard library....

@meetingcpp The indexes are not correct. If you fix that then it's the same as visit (and can be simplified to use get rather than get_if): quick-bench.com/q/TTSlqnz7S0KR…

But there is a faster way, doing a switch(index()) removes the if/else nightmare. When then changing to std::get I get a timeout though. quick-bench.com/q/sB0-3axOAnkz…

Wondering how to access a variants members, get_if is so much better then visit? quick-bench.com/q/2TU5-QJ4fpCX… #cpp #cplusplus

@ericniebler If you want to keep all of the conflict resolutions from the commit you've already made, you can do `git merge -s ours <commit-hash>` to create a merge commit that doesn't make any actual changes.

Git experts! I somehow committed a complex merge as a regular commit instead of a merge commit. Now git thinks all those merged commits are still unmerged. How do I tell git, "you've already done this merge up to <commit-hash>, trust me"?

I have spoken at CppCon in the past. I will not do so again, or attend, unless this is sorted out satisfactorily. I fully support Patricia's stance on this and have signed her open letter.

@parsley72 @michtiecpp @auckland_cpp Me too :(

@michtiecpp @auckland_cpp Ah crap, I forgot.

Yes, it was great to reconnect. Thanks for organising it, Paul.

Here's the invite link for our Slack workspace: join.slack.com/t/aucklandcpp/…

@tvaneerd This reminds me of a video about the code review process at Jane Street, where they talk about committing the review comments themselves as comments in the source code. janestreet.com/tech-talks/jan…

If someone asks a question in a code review, 9 times out of 10, instead of answering in the code review, change the code such that the question would not have been asked. (9/10 may be a bit high, but I'd say at least 7/10 from my experience, YMMV, depends on your team, etc etc.)

Here's a progressive coupon for my book, C++ Best Practices, good for 36 hrs from now. The coupon starts at 9.99 USD. For each retweet this gets, I'll reduce the price by 0.01 USD. The maximum reduction is 700 retweets @ 2.99 USD for the book! leanpub.com/cppbestpractic…

@parsley72 I've _definitely_ never done that...

@toby_allsopp Yeah, I forgot the ‘<‘.

Ran “patch —dry-run” on this kernel source about 20 mins ago and it’s still going. Is this good or bad?

@TartanLlama @seanbax The problem (well one of the problems) you'll run into is that with c++ coroutines you can't invoke the continuation more than once, which I imagine is needed for parsing lists, for example. Maybe you can avoid that when using parser combinators?

@seanbax For abusing the customisation points of coroutines to use them like general syntax for monads, like this github.com/toby-allsopp/c…

Has anyone written a parser combinator library with C++20 coroutines yet?

I'm looking for people excited about working with Rust to join me in developing performant software for photographers, get in touch if this sounds like you! Based in Auckland, NZ. narrative.so/job/rust-engin…
