I’ve been playing with #ProjectValhalla and the new #Java Value Classes (JEP 401), and I thought: “What happens if Protobuf messages become value classes?” 🤔 So I wrote a small protoc plugin and ran a few experiments: dariobalinzo.medium.com/protobuf-mee...
Protobuf meets Valhalla — hacking with Java Value Classes (JEP 401)
I like messing with new Java features. This time I tried combining value classes (JEP 401) with Protocol Buffers, not because I needed to…

I wrote this blog post to share some hacking sessions with the new #Java #Virtual #Threads. While these are new and cool tools, they can hide new pitfalls to solve.. see the details in the post! dariobalinzo.medium.com/virtual-thre... #java24 #performance
Virtual Threads Ate My Memory: A Web Crawler’s Tale of Speed vs. Memory
I built a simple web crawler using good old platform threads. It was just a multithreaded crawler, nothing fancy. But then, curiosity…

Usually when we think about synchronization mechanisms between threads we focus on mutual exclusion. 🔒 An important aspect is also memory visibility...🧵 #java www.cs.umd.edu/~pugh/java/m...
In multiprocessor systems, processors generally have one or more layers of memory cache, which improves performance both by speeding access to data (because the data is closer to the processor) and reducing traffic on the shared memory bus (because many memory operations can be satisfied by local caches.) Memory caches can improve performance tremendously, but they present a host of new challenges. What, for example, happens when two processors examine the same memory location at the same time? Under what conditions will they see the same value?
