Show HN: ONNX optimized SigLIP and related foundation models https://ift.tt/lTGJ6PC

Show HN: ONNX optimized SigLIP and related foundation models Hey there Hacker News! Long time lurker but first time posting so nice to meet you all! I have some time on my hands so I got down a rabbit hole and created a project to keep track of, and unify a bunch of optimized foundation models under one easy to use Python package. So far I have the following up and running:- SigLIP as a FP16 ONNX representation for super fast zero-shot classification image classification - quantized model support is on it’s way Automatic pre and post processing switching - choosing CLIP as a model type falls back to cosine similarity with softmax, where SigLIP falls back to its full graph with a Scipy based sigmoid output activation. Manual mode with exposed image and text encoders for each model - SigLIP also has it’s pre-pooled hidden output available for analysis etc An ONNX Segment Anything representation - the plan is to have each CLIP/SigLIP model’s salient map feed directly as a multi-point prompt to SAM and its variants. More on this soon!The plan is to have the same usage wrap a TensorRT backend along the road, and tie that into Chromadb for super fast search but for now check out the example Gradio app. It’s still a little clunky but the results are pretty impressive! I’d imagine this would be great for lightweight RAG too! https://ift.tt/0vhSTZO June 21, 2024 at 11:58PM

Show HN: Interactive exercises for GNU grep, sed and awk https://ift.tt/OxeFwah

Show HN: Interactive exercises for GNU grep, sed and awk Hello! For the past few months, I've been using a Python framework called Textual to create TUI apps for interactive exercises. Released the app for GNU awk earlier today, so thought I'd create a post here. If you already know how to manage Python packages, you can use the following command to get all the three apps: pip install grepexercises sedexercises awkexercises `pipx` should also work, but I haven't tested it. The GitHub repo has the source code as well as more detailed installation instructions. You can use alternative CLI tools to solve these exercises as well. For example, Perl instead of GNU awk or ripgrep instead of GNU grep and so on. Hope you find these TUI apps useful. I'd highly appreciate your feedback. Happy learning :) https://ift.tt/Hp9kFEi August 17, 2023 at 05:13PM

Show HN: My Book Bulletproof TLS and PKI (Second Edition) Is Out https://ift.tt/5PZ9mxF

Show HN: My Book Bulletproof TLS and PKI (Second Edition) Is Out Hello HN. I am excited to share with you my new book, Bulletproof TLS and PKI. I've worked in this space since the very early days (think SSLv2), always frustrated with the fact that the field is vast but the documentation poor. That first led me to create SSL Labs (which ended up being very popular) and then the first edition of my book (in 2014), where I aimed to cover everything a curious person needed to know about SSL/TLS and PKI. Most importantly, it's a very practical book that you can use to just learn what you need at that moment. The second edition (just out) adds coverage of TLS 1.3. I publish two chapters as a separate (and free) OpenSSL Cookbook. There's another free sample chapter as well. The best part of Bulletproof TLS and PKI is that it's a living book. There's nothing worse than obsolete documentation! Because none of the traditional publishers were interested in that sort of thing,
