If you’ve been thinking about upgrading your gaming monitor, LG’s 27-inch 27GX704A-B pairs a glossy WOLED panel with a fast refresh rate, and it’s currently on sale for $379.99 (about $70 off) at Amazon and directly from LG, marking a new low price. It originally launched at $799.99, but has been available for under $500 since […]

Hi HN, I’m Alex Southmayd, the founder of Bloomy ( https://bloomylearning.com ) – an AI-powered mastery-learning platform for K-12 students. Bloomy provides students with an AI tutor alongside adaptive curriculum (right now Math, English Language Arts, and Writing). How it works: we diagnose students’ skill gaps, place them on personalized learning paths, and give them standards-aligned lessons and a Socratic AI tutor that scaffolds their learning without just giving away the answer. The goal is

I worked on this project ( https://github.com/workofart/harness-training ) for the past few months to reframe "Agent-driven Self-improving Harness" to "Harness Training". The idea is simple, the harness is trained once with a frozen task LLM against a given task environment. Then you can then swap out the task LLM to any model and evaluate the "frozen trained harness" with any task LLM on any new task environment. Since this was a general problem, I took the chance to create a general PyTorch-like training framework. Right now, you can train with any OpenAI-compatible API for interfacing with the task LLM and train against Terminal-Bench or SWE-Bench tasks, but you can easily extend it to support any task environments. criterion = StrictPareto() optimizer = GreedyMonotonic() trainer = Trainer( config_path="config/train_harness.yaml", estimator=AgenticEstimator( backend=CodexAgentBackend(...) ), criterion=criterion, optimizer=optimizer, ) for loss in trainer.epochs(30): # Records the baseline-vs-candidate verdict loss.backward() # Optimizer either fast-forwards the candidate change (git commit) as a new baseline or rejects it (preserved as git ref) optimizer.step() I wrote a blog post ( https://www.henrypan.com/blog/2026-07-18-harness-training ) on this journey, including (but not limited to): results from using this harness training framework to improve general capabilities across many task LLMs to beat Terminal Bench 2.0 (Terminus Harness) and also transfer learnings towards better task-solving abilities in unseen task environments (e.g. harness trained on SWE-Bench tasks solving Terminal Bench tasks). how this framework is built learnings on what was missing in my initial version of the project (hint: determinism) Any feedback is appreciated.

Pretty cool seeing that people were already thinking about memory safety decades ago. Some of these ideas that feel modern today were being explored back in the 80s and 90s. Makes you wonder how different things would look if languages like Modula-3 had taken off. submitted by /u/FayeTammy [link] [留言]

A video from Gamers Nexus explains how, after connecting a new LG UltraGear monitor to a PC running Windows 11 for the first time, Windows Update is silently installing LG driver updates and the LG Monitor App Installer, without so much as a permission pop-up or notification. The app doesn't appear to include special controls […]

Adobe's experimental camera app has taken an unexpected turn. After Project Indigo was launched last year to provide a "more natural (SLR-like) look" for iPhone photography, the Indigo camera app is now being updated with a suite of generative AI tools. And the change doesn't rely upon Adobe's own Firefly AI models. Adobe describes the […]
