I've been thinking today about modules, objects and values.

(Thread 🧵)

[Juanpe Bolívar @sinusoidalen]

This is happening in an hour. Come over if you're in Berlin :)

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.

[Juanpe Bolívar @sinusoidalen]

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!

[Juanpe Bolívar @sinusoidalen]

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! 😭

[Juanpe Bolívar @sinusoidalen]

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!

[Juanpe Bolívar @sinusoidalen]

@matt_dz Aha! Thank you!

[Juanpe Bolívar @sinusoidalen]

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? 🤔

[Juanpe Bolívar @sinusoidalen]

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!

[Juanpe Bolívar @sinusoidalen]

Something to push through the week.

@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!

[Juanpe Bolívar @sinusoidalen]

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

@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! 📨

[Juanpe Bolívar @sinusoidalen]

@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...

[Alex George Pickering @AlexGPickering]

Indeed.

[Juanpe Bolívar @sinusoidalen]

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

[Juanpe Bolívar @sinusoidalen]

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? ⁉️

[Juanpe Bolívar @sinusoidalen]

Ping @odinthenerd. Who else?
