Show HN: FlowTracker – Track data flowing through Java programs
Last time I was this blown away was with jitwatch ( https://github.com/AdoptOpenJDK/jitwatch )
FlowTracker reminds me a little of taint analysis, which is used for tracking unvalidated user inputs or secrets through a program, making sure it is not leaked or used without validation.
search keywords are "dynamic taint tracking/analysis"

It's 2023, so of course I'm learning Common Lisp
You can kind of do the same as DISASSEMBLE in Clojure.
There are some helper projects like https://github.com/Bronsa/tools.decompiler, and on the OpenJDK JitWatch (https://github.com/AdoptOpenJDK/jitwatch), other JVMs have similar tools as well.
It isn't as straightforward as in Lisp, but it is nonetheless doable.

How much is too much? 380+ lines of an AssertionUtil class Or Loggin classes in general.
As you have encapsulated the asserts inside methods, these will be called at runtime with the arguments evaluated (for example, creating that lambda). When assertions are disabled, the C1/C2 may inline the empty method call eventually, but I don't know whether it drops the lambda instantiation as well. You can use JITWatch to see what gets inlined. The general notion though is to not worry too much. Lazy log messages are a common pattern.

JIT x86 ia32
You can use jitwatch for this. To see the actual assembly code generated you will also need to use a debug build of the jvm.

SIMD accelerated sorting in Java – how it works and why it was 3x faster
If you use Oracle's own IDE, it will support it out of the box, as it already did on Sun's days.
Then there are other ways depending on which JVM implementation is used.
On OpenJDK's case you can load runtime plugin to do it

Why Zig When There Is Already C++ and Rust?
If you already know any JVM or .NET language, the first step would be to understand the full stack, you don't need C for that.
Many of us were doing systems programming with other languages before C went mainstream.
What you need to learn is computer architecture.
Getting back to JVM or .NET, you can get hold of JIT Watch, VS debug mode or play online in SharpLab.
Get to understand how some code gets translated into MSIL/JVM, and how those bytecodes end up being converted into machine code.

Languages like F# and C# allow you to leave the high level comfort and also do most of the stuff you would be doing in C.
Or just pick D, which provides the same comfort and goes even further in low level capabilities.
Use them to write a toy compiler, userspace driver, talking to GPIO pins in a PI, manipulating B-Tree data stuctures directly from inodes, a TCP/IP userspace driver.
Not advocating not to learn Zig, do it still, the more languages one learns the better.
Only advocating what might be an easier transition path into learning about systems programming concepts.
