Show HN: I've developed an open-source proxy server for front end applications Hey Everyone! I’ve recently been working on an open-source proxy server to help front end applications securely access third party APIs that require confidential API keys without the need to create your own backend. I would love to get some feedback and hear what you think! https://ift.tt/zu5fUDd April 25, 2024 at 05:32AM

Show HN: Storing Private Keys in the Browser Securely https://ift.tt/wCZ2GNK

Show HN: Storing Private Keys in the Browser Securely So the main purpose here is to show _a_ way that session-token theft can be mitigated. Clearly, this isn't NSA proof or something you'd use to secure a BL5 containment facility, but to prevent session-jacking; if feels like it could help a lot, and would be pretty quick and easy to roll out if an IDP wanted to implement it. https://ift.tt/XrUYbsc April 24, 2024 at 12:32AM

Show HN: Metashade – a Pythonic GPU shading/compute EDSL Superficially, it may look similar to Nvidia's Warp or OpenAI's Triton, but instead of transpiling a subset of Python to the target language, it implements dynamic codegen in pure Python. These slides discuss the existing GPU programming solutions and make a case for Metashade's approach: https://ift.tt/9enzb6N... https://ift.tt/BvxgTmd April 22, 2024 at 04:51AM

Show HN: Auto-optimizing deterministic LLM outputs using knowledge graphs https://ift.tt/cVsnF9k

Show HN: Auto-optimizing deterministic LLM outputs using knowledge graphs Hi, We are building an open-source framework for loading and structuring LLM context to create accurate and explainable LLM answers using knowledge graphs and vector stores. We built the tool with four main concepts in mind: 1. Loader -> uses dlt in the backend to load and structure the data 2. Cognify step -> creates a graph with summaries, labels and factoids that are interconnected across the documents and stored as a representation in the vector store 3. Optimizer -> Uses DSPy to optimize LLM queries, and we plan to extend it to most of the knobs we can turn, like chunking etc. 4. Search -> allows for searching using search types supported in graph stores (ex. Neo4j) or hybrid, BM25, or other search types available in vector stores. We are quite early with the product but we would love to hear feedback on what we can improve. https://ift.tt/iymv0eR April 22, 2024 at 11:55PM

Show HN: Fast Calendar Algorithms https://ift.tt/y2I4WSr

Show HN: Fast Calendar Algorithms I've done this work not long ago and I reckon that the name of the github repo doesn't help people searching for calendar algorithms. (Too late to change it now.) The name of the repo, eaf, comes from Euclidean Affine Functions which are the type of functions behind the algorithms. https://ift.tt/SRNLV6B April 22, 2024 at 06:32AM

Show HN: AppView 1.0.0 is released Instrument, Observe, Secure your deployments https://ift.tt/HiJrcYS

Show HN: AppView 1.0.0 is released Instrument, Observe, Secure your deployments AppView is an open source, runtime-agnostic instrumentation utility for any Linux command or application. It helps users to explore, understand, and gain visibility with no code modification. With one instrumentation approach for all runtimes, AppView offers ubiquitous, unified instrumentation of any unmodified Linux executable. With AppView 1.0.0 comes the new threat detection logic that allows users to capture security-related events. Is your application accessing secure files? Is it making connections it shouldn't be? Is it exfiltrating data over DNS or is GOT poisoning in effect? Other features of the 1.0.0 release include the ability to: - Generate metrics on process and application performance. - Generate events, reporting on network, file, logs, console messages and http/s activity. - Capture (decrypted) payload data without the need for keys. - Generate a stack trace, and a core dump when an application crashes. - Generate network flow information. - Create a report on unique file and network activity. - Install AppView in a Kubernetes cluster. - Secure file and network access in an application. - Instrument both static and dynamic executables. - Attach to processes while they are running or start when the process does. - Normalize and forward metrics and events, in real time, to remote systems. - Summarize metrics and detect protocols. We are looking for users and contributors alike. https://appview.org/ April 21, 2024 at 10:52PM

Show HN: What Are You Working On? https://ift.tt/KpGwhvQ

Show HN: What Are You Working On? Hey HN, I'm sure you've seen the monthly "Ask HN: What Are You Working On?" headlines on [Hacker News]( https://ift.tt/kuHOVCQ... ). Honestly, it's my favorite topic because it's packed with insights about what other hackers are up to. I wondered what it would be like if instead of just a headline, there was a whole website where hackers could post daily updates, and where we could follow the hackers we're interested in for their latest updates. And so, this web site was born. I hope it gets used frequently so we can all benefit from it together. I look forward to hearing your thoughts. Let me know what you think! https://ift.tt/4acdygo April 21, 2024 at 05:13PM
