Show HN: PantheonGPU – GPU health testing and AI workload benchmarking https://ift.tt/2mP7hpz

Show HN: PantheonGPU – GPU health testing and AI workload benchmarking Hi HN, I built PantheonGPU because I wanted a better way to answer a simple question: is this GPU actually healthy and performing the way it should? A GPU can show normal temperatures and utilization and still be underperforming, unstable under certain workloads, or have memory, PCIe, or configuration issues. PantheonGPU actively tests the GPU instead of only monitoring telemetry. It currently includes 45+ tests covering compute, tensor workloads, memory, cache, PCIe, thermals, stability, and AI/LLM inference. It supports both NVIDIA CUDA and AMD ROCm. I’m also exploring a larger use case: running Pantheon across GPU fleets to identify individual GPUs that behave differently from the rest of a server or cluster. I’d especially appreciate feedback from people running AI infrastructure, multi-GPU systems, local LLMs, or GPU clouds. https://ift.tt/6UeoXLk August 19, 2026 at 12:17AM

Show HN: macOS data protection keychain for Electron apps https://ift.tt/CIqdG9W

Show HN: macOS data protection keychain for Electron apps Hey HN, I've been working on Hansel [1] (an encrypted personal data store you can query with agents), and there wasn't a good way to use the modern macOS Data Protection Keychain. Electron's safeStorage [2] uses the legacy file-based keychain, which allows other apps/agents to query it with the `security` CLI. Not great when you have a dozen agents running in the background! The Data Protection Keychain is nice because it limits access via code-signing access groups and lets you set access rules like Touch ID and/or password. 1: https://hansel.so/ 2. https://ift.tt/kVjP38w https://ift.tt/IEz3bes August 18, 2026 at 10:55PM

Show HN: PageSieve, a web scraping browser extension https://ift.tt/z6MTsLy

Show HN: PageSieve, a web scraping browser extension PageSieve[1] is a browser extension for scraping data from different websites from within your browser. Currently it's Firefox only but I am open to porting it to other browsers if that's something people want. My original motivation for this started with a desire to improve the capabilities of the selectorgadget[2] bookmarklet to support extracting as well as finding selectors. The ideal use case is when some data you need is useful but you don't want to spend the effort of writing a one-off script to extract it especially nowadays when a lot of websites need an entire JavaScript environment to load correctly which complicates scraping. Using this extension means you only need to maintain the selectors for extracting the data and don't need to worry about managing dependencies. As long as the website can be opened in your browser you should be able to scrape data from it using the extension. I have a lot of features...
