Gradle - sharing and tuning the build logic among monorepos by Jiri Mikulasek
Переглядів 2202 місяці тому
Gradle is one of the most spread tools for building kotlin (and java) applications. It is powerful beast which can serve you well but can also bite. Despite thorough documentation and many public resources, there are also many myths. Also few is can be found about organizing the builds in monorepos. In this talk, I will share my experience of refactoring the wild legacy of multimodule builds in...
Asynchronous and Concurrent Programming - Kotlin Coroutines and Loom (CZ) by Stepan Mik

Vyplatí se přejít na R2DBC, jaký dopad bude mít Project Loom by Jiri Hermann
Переглядів 415 місяців тому
Srovnání dvou populárních frameworků pro webový vývoj v Kotlinu a Javě: Spring Web a Spring WebFlux. Budeme zkoumat jejich schopnost zpracovávat příchozí požadavky a pracovat s JDBC drivery, které jsou klíčové pro práci s databázemi. Dále se podíváme na projekt Loom, který přináší nový přístup k paralelnímu zpracování v Javě, a zjistíme, zda může přiblížit výkonostní úrovně Spring WebFluxu. 00:...
I would've loved to see some examples of how you handled composing build logic together. I found the questions/answers at the end to be most informative and interesting. I'd love to hear you speak more about this
Save yourself 44m30s on the convoluted storey time over an 'interesting' viewpoint of exceptions and watch the 30sec of project Arrow on show. Then go find a primer for Kotlin project Arrow and resume your education there. Sorry the style is not to my taste too many cringey soundbites on incomplete takes concerning other languages and contexts around the points presented. C has both GOTO types the other is using libc setjmp. Threads get their own stack executation is not an uncontrolled free for all. The beauty of exceptions is they perform controlled stack unwinding. My fellow coworkers and open source dependencies don't cause the problems you imply they do. Straw person much ?
this guy fucks
Nice presentation! Thank you! :)
Great speech, thank you!
Díky za záznam skvělé přednášky, co jsem bohužel kvuli produkční issue nestihl na živo
Jsme moc rádi že nás sledujete :)
