CEASTA

ceasta is a single C++ tool that combines an IDA-style disassembler, a pseudocode decompiler, a function graph, and an x64dbg-style debugger for PE, ELF, and raw shellcode, with a full GUI on Windows and a CLI with a ptrace debugger on Linux. Its built-in MCP server (ceasta-cli mcp target.exe) lets Claude Code or Cursor decompile, rename, and diff builds. With --allow-debug, it can also set breakpoints and call functions in the running process. The decompiler is best-effort, with no types or structs yet.

MODEL OPTIMIZER

NVIDIA has open sourced its Model Optimizer library, which offers techniques like quantization, pruning, and distillation to accelerate deep learning models. The tool supports inputs from Hugging Face, PyTorch, or ONNX and exports optimized checkpoints for deployment frameworks like TensorRT-LLM and vLLM. Users can install the stable release via PyPI or use NVIDIA container images with the software pre-installed.
