Show HN: Process your solar eclipse data https://ift.tt/KirMvkS

Show HN: Process your solar eclipse data I've been sitting on some video of the 2024 solar eclipse (448gb specifically). All the interest about the most recent one one in spain inspired me to vibe code something that would stabilize and make pretty my data. I'm looking for other test data to make the pipeline more generalized. I made this would claude code and opus 5. https://ift.tt/wLp3HSJ August 20, 2026 at 11:11PM

Show HN: PantheonGPU – GPU health testing and AI workload benchmarking https://ift.tt/d5qrcRg

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/aiJDrYm August 19, 2026 at 12:17AM

Show HN: macOS data protection keychain for Electron apps https://ift.tt/G0XY5sJ

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/wLoTtkc https://ift.tt/32vLHe4 August 18, 2026 at 10:55PM
