ABSTRACT
Suppose you want a new feature which requires a lower-level language to get the performance it needs. Or maybe your code is already low-level, but a new feature could be built much faster in a higher-level language without a noticeable performance hit. Or maybe you want to migrate incrementally from one language to another.
Whatever the motivation, calling functions across languages while staying within the same process is commonly overlooked in favor of more familiar techniques like spinning up a separate server for the other language to use, or at least another process. These can not only introduce performance problems, but also an infrastructure maintenance burden that can be avoided with direct calls.
This talk explores the technique of directly calling functions across languages by looking at how it works in several different languages, the tradeoffs compared to other techniques like separate servers and processes, and when and why you might want to use it.
Come see how calling functions across languages could benefit your project! [...]

Wisconsin represent 💯
How is this guy so good at presentations got damn, literally every one of his talks are super easy to follow along with.
Especially if you listen to him at 0.85x .
Practice I guess.@@encapsulatio
checkout his talk about teaching Elm, he explains how he thinks about teaching in general
With roc, he became my favorite man, talk on the happy path programming, still new to functions and really into f#
Richard’s presentations have actually changed my life with career opportunities. As soon as there is a decent Roc lsp I’m switching!
What a great teacher!
I came to listen about roc, learned how processor works. :). Always awesome to listen Richard.
Kudos for your hard work. Your channel is top-notch.
Fortran has been updated many times since 1957😂
Recently some people who grew up with JavaScript added an actually pretty decent Fortran Package Manager (fpm). And the code even looks pretty reasonable, compared to the old 100 SCREAMING CASE SYNTAX. 😅
can't believe there's no "crossing the Rubicon" pun in this
Years ago when I worked at Borland we created libraries that did exactly this where you could call C/C++ from Pascal or machine language or vice versa…. While at NASA I extended this idea using Elf and Dwarf that used a wrapper/converter that simplified this whole process…
"shared memory" as in mmap can be shared between unrelated processes when file backed (MAP_SHARED), right? `shm_open()` or `memfd_create()` would be other options.
Perhaps protobuf...?
Fun and interesting. Also some Louis CK vibes.
Calling Cobol !!!
It's a real world use case. I remember reading about how a state in the US has it's driver's license software running in Cobol. They ended up using node-cobol to modernize their app.
