Show HN: Make your logo extra bright on HDR screens Certain logos started standing out to me on LinkedIn as brighter/whiter than everything else around them. I dug in and found out this is accomplished by adding a gain-map to an existing JPEG, visible only on HDR screens like a newer MacBook Pro. LinkedIn is the only social network I've found that isn't stripping them out, but of course you serve them up on your own site. I worked with Claude Code to turn it into a little browser-based utility (no registration) and hope you find it useful! https://ift.tt/ntY5XF7 August 23, 2026 at 12:13AM

Show HN: All your saved articles in one place https://ift.tt/ldJkzW5

Show HN: All your saved articles in one place Hi HN. I would love to show you beta preview of Topics. Articles on the internet are organized by source (publications, social media, personal websites), by recency, or by position in search. I believe it’s nicer for the reader if articles are organized by Topics. Topics solve problem of decision fatigue, omnipresent AI slop, and people stopping to trust writing on internet and stopping to read. I'm grateful for any feedback you might have. TOpics app is launching soon. X: @topics_official. https://ift.tt/4hK1sej August 21, 2026 at 11:01PM

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
