jOOR
jOOR - Fluent Reflection in Java jOOR is a very simple fluent API that gives access to your Java Class structures in a more intuitive way. The JDK's reflection APIs are hard and verbose to use. Other languages have much simpler constructs to access type meta information at runtime. Let us make Java reflection better.

Objenesis
Okay, it's pretty easy to instantiate objects in Java through standard reflection. However there are many cases where you need to go beyond what reflection provides. For example, if there's no public constructor, you want to bypass the constructor code, or set final fields. There are numerous clever (but fiddly) approaches to getting around this and this library provides a simple way to get at them. You will find the official site here.

that's surprising considering `pry`[1] is such an amazing debugger IMO.

Project mention: Can I add a blinking cursor to a TextField when using a custom keyboard? | /r/swift | 2023-07-06The SwiftUI Introspect package can probably help here. I know what the correct implementation is for NSLayoutManager in macOS, but I haven’t tried it in iOS.
I really like magic-trace [0].
https://github.com/janestreet/magic-trace
Not that the exact tracing relies on Intel PT - support for AMD was added recently but uses perf so suffers from the same sampling/skew issues, but is still very useful.
Sum types and pattern matching have already been hacked together in a preprocessor macro in C; see https://github.com/Hirrolot/datatype99.
Project mention: Memflow: Live memory introspection of running systems | news.ycombinator.com | 2023-12-15
Project mention: Scaling GraphQL Subscriptions in Go with Epoll and Event Driven Architecture | dev.to | 2024-03-04If you're interested in the full implementation of the resolver, you can find it on GitHub.
Project mention: Meta's Onavo VPN removed SSL encryption of competitor's analytics traffic | news.ycombinator.com | 2024-03-31They can see the traffic only if you're using one of their load balancers. And even if not, snooping on VMs is pretty trivial. For example this project https://github.com/KVM-VMI/kvm-vmi makes it easy to look at memory / processes on a VM.
Project mention: sift 0.12.0: A CLI tool for Reverse Modeling JVM Applications, Now With Improved Kotlin Support! | /r/Kotlin | 2023-06-22The latest release brings kotlin language support to sift's class parsing. This means that kotlin constructs - including value classes and extension functions - always report the correct name. Full changelog here: https://github.com/junkdog/sift/releases/tag/sift-0.12.0
