   Hi HN, author here. I've been working on optimizing perception pipelines for SWaP-constrained FPGAs (like in satellite or drone payloads). I realized that we often run out of DSP slices for simple 3x3 convolutions. I implemented a meth

   Thanks for the feedback! You hit the nail on the head regarding the trade-offs. 1. Latency & Thrashing: You are absolutely right, there is overhead (context switch + LZ4). The intended use case isn't high-frequency access to hot da

   Hi HN, I wrote a C++ library that implements transparent memory compression in user-space. Up to 100% if you use it right ^^ The core idea is to catch memory access violations (using AddVectoredExceptionHandler on Windows or userfaultfd&#x2

   I'm late for the party, but I create a tiny but useful C / C++ build system called Bodge that is equipped to build small C++ projects. Can be found here: https://github.com/el-dockerr/bodge . You simply define
