Too few sampled comments (6) to say how often HN recommends it.?
Why HN links it
HN readers link rev.ng's blog for decompiler and reverse-engineering write-ups, such as 'Reinvent the Wheel' on shared versus static libraries, and a bashML post on using Bash, comm and awk instead of Spark.
Summarised by Claude from a sample of 6 HN comments that link here. Each comment is marked recommending, critical or neutral (citing without judging); how this works.
Next-gen decompiler.

What Hacker News says?
I think this finally answers a question I've had since I started learning programming. All my life I've been told "you can't convert a shared library to a static library". When you try to probe for more details, all you get is some mumbling about how a shared library is already prelinked for mapping into memory so the relocation table is lost. When you press further about the precise information loss that prevents y…

HN discussionAs others have said, the standardization of metrics is still something debated, but at the same time, this space has been explored by various top-tier papers that your paper did not cite. For example, DREAM [1], evaluated using the classic metric of goto-emittence. Rev.ng [2], evaluated using Cyclomatic Complexity and gotos. SAILR [3], evaluated using the previous metrics and a Graph Edit Distance score for the stru…

HN discussionYou can do a lot with just bash + pipes + unix tools. It can get messy as your pipeline grows though, and there are a lot of edge cases. Relevant: "bashML: Why Spark when you can Bash?" ( https://rev.ng/blog/bashml/post.html ), aka how to deduplicate git repositories using `comm` + `awk`.

HN discussionShort answer: if you want to execute a program (maybe with some instrumentation, for fuzzing purposes) it's much easier to adopt a dynamic approach (i.e., emulation or virtualization). With static binary translation you can get better performance, but there's a lot of other things you need to get 100% right and that with a dynamic approach are a given (e.g., the CFG). There's much more space of improvement in the fi…

HN discussion> architectural registers are always updated In tiny code, the guest registers (global TCG variables) are stored in the host's registers until you either call an helper which can access the CPU state or you return (`git grep la_global_sync`). This is the reason why QEMU is not so terribly slow. But after a check, this also happens when you access the guest memory address space! https://github.com/qemu/qemu/blob/mast…

HN discussion> Do you have examples of your decompilation, and how it compares to state of the art that uses other approaches? We don't have any exhaustive comparison, and for sure IDA are better than what we currently produce in many aspects (we're not at 1.0 release), but I can tell you where we want to go: 1. Automatic data structures detection: our goal is to basically never emit pointer arithmetic but automatically reconstr…

HN discussionHey, rev.ng core dev here. I guess the core difference is that we do not implement the instructions semantics ourselves, but we reuse QEMU. QEMU, when in emulation mode (i.e., not KVM), goes from executable code to an intermediate representation (tiny code instructions) and then compile it back to the host architecture. We use the first part of QEMU but then translate tiny code instructions into LLVM IR. This means…
