Juanpe Bolívar

I've been thinking today about modules, objects and values. (Thread 🧵)

Hi people! Can some of you introduce me to someone that works on Steam? 🚀 Someone on the product or business side would work. Would like to discuss some business ideas connected to the Steam (shop) platform.

I will be bringing my talk "Persistence squared: persisting persistent data structures" to @meetingcpp! Learn how new features in immutable data structures open novel software architectures enabling performance while making the code simpler! 🚀

@ivan_cukic @meetingcpp Indeed... been mostly out of the conference cycle since the pandemic. Looking forward to see you there!

@meetingcpp Cool, I haven't seen Juan in ages :)

New talk at Meeting C++ 2025: Juan Pedro Bolívar Puente - Persistence squared: persisting persistent data structures meetingcpp.com/mcpp/schedule/… #meetingcpp #cpp #cplusplus

Last time I attended a conference in person was 2019 (before the pandemic!) and 2021 was my last CppCon talk (online!). I can't wait to meet you all in person, I've been missing this! 😭

I'm excited to be talking again at CppCon, presenting immer::persist, a library to serialize and transform immutable data structures, preserving the structural sharing. Cool work by Alex Shabaling and @bronze_ai enabling all new kinds of applications! sched.co/28JnX

@matt_dz Aha! Thank you!

@sinusoidalen Hidden friend idiom, reduces compile time (measurably: jacquesheunis.com/post/hidden-fr…) by effectively removing the overloaded operators from the overload candidate set (removing error message spam, e.g., @ 43:52 in "The Art of C++ Friendship" by Mateusz Pusz, youtube.com/watch?v=9J4-8v…).

C++ experts: is there a reason why default comparison operators need to me marked friend, even when all members of the struct are public, other than C++ being a massive PITA even when loaded with all the best intentions? 🤔 en.cppreference.com/w/cpp/language…

Hey! I will be traveling around the US for the next couple of months, mostly in SF but also staying in Portland and NY. ✈️ I'm very flexible, mostly visiting friends and exploring the nature. If you're around and would like to hang out and exchange ideas in person, send me a DM!

Something to push through the week. soundcloud.com/internet_mp3/h…

@ColugoMusic @bronze_ai Super appreciated! 🙏Glad you took these ideas as inspiration and manged to find your own way of doing things. It's not a dogma but some guiding principles that can be applied differently facing different trade-offs. And I love what you're building with Blockhead, impressive!

@sinusoidalen @bronze_ai Your talks on YouTube had a massive influence on my approach to application development over the past few years, even though I did not end up taking a purely value oriented approach (I fell into my own hybrid of data-oriented design + unidirectional data flow architecture)

We've finnally merged `immer::persist` into Immer 🎉 It serializes and transforms the internal structure of pools of Immer containers, preserving the structural sharing across containers. Use-cases: storing undo history, clipboards, logging... Big deal sinusoid.es/immer/persist/…

@bronze_ai Don't doubt: my confidence and commitment to value-oriented design is as strong as ever! You'd be shocked how simple and performant some of the otherwise complex projects I've been helping my clients build are👷‍♂️ I've some consulting slots on the side if you're interested! 📨

@bronze_ai The pandemic first and then my focus on BRONZE have made be a bit more low key and get a bit out of touch with the in person gatherings of the C++ community. I miss you all! Hopefully will get back on it soon presenting this and some of the other cool stuff we're building...

Indeed.

Forgot to mentio we're on C++ 20 :)

Ping @odinthenerd. Who else?

Hi C++ Twitter! We're having some trouble with some meta-programming intensive code that is too slow and likes making Clang crash 💥 Using Boost.Hana now but I know there are way faster alternatives. Any library suggestions? Meta profiling tools? Etc? ⁉️

Here are some programming talks (mostly c++) which i have watched and enjoyed either because they are interesting or useful or funny or otherwise entertaining
