Ask HN: Time loop and partial blackhole?https://news.ycombinator.com/item?id=48402378Hello. I am a 9th grade student from India.AI was used only for grammar correction. These are my own questions.I am confused about two concepts:1. Second Law of Thermodynamics: It states that the entropy of an isolated system increases. Decreasing entropy requires work. Does this imply that while time dilation from General Relativity can cause time to pass slower, time can never run backwards, as that would require a spontaneous decrease in entropy?2. General Relativity: Time passes slower in stronger gravitational fields. As a mental model, is it partially correct to visualize this as the rate of atomic vibrations/motion decreasing in strong gravity, causing clocks to tick slower?I am not proposing a new theory. I am asking to identify flaws in my current understanding. Please explain at a high school level.Thank you for your time.

Show HN: Boxes.dev: ditch localhost; run Claude Code and Codex in the cloudhttps://boxes.devHi HN, we’re Nick and Drew, and we’re building boxes.dev – the first cloud-only agentic dev environment (ADE) that gives every Codex and Claude Code agent its own cloud computer.We’re two engineers who previously built Gem (co-founder/CTO and first hire), and we spent the last year coding almost exclusively using Codex and Claude Code. It’s been a huge change to how we code, and it’s been exhilarating seeing the models keep getting better – but we eventually realized that developing on localhost was holding us back:- Git worktrees are clunky to set up and use for parallelizing work - It’s 2026, but somehow everyone is still walking around with laptops cracked open or SSHing into mac minis in their garage so their agents don’t stop working. - Mobile is treated like an afterthought even though coding is just texting now We started hitting resource constraints when multiple parallel agents test their own work by running the full app locally. - We tried different products, but couldn’t fin

Google killed my $1M ARR startup overnighthttps://news.ycombinator.com/item?id=48396596Two days ago I had a working company. $1M ARR, 100k users, a product people actually pay for and depend on. Right now it's dead in the water and I'm locked out of all of it, because Google decided to suspend my entire account.Someone got hold of one of my API keys and ran up charges on Google's AI services that I never touched. $4,200 hit my card for usage that wasn't mine. Fine, happens I paid the bill. But Google suspended my whole project. Everything lived in there. The backend, and every single customer photo, over a million of them.So now my users open the app and nothing loads. I can't fix it because I can't even get into the console anymore, they took that away too.I've spent two days appealing, paying for support just to reach a real human, getting "escalated," and mostly sitting in an automated queue while my business bleeds. No real answer. No timeline. Nothing.I trusted Google Cloud to hold my customers' data and run my company. Two days of downtime over a charge I didn't ma

Show HN: Realistic procedural fire effect via naive algorithmhttps://fx.leftium.com/fire-plasmaSource code: https://github.com/Leftium/fx/blob/main/src/routes/fire-plas...I made this naive fire effect as realistic as possible; arguably more realistic than some simulations based on real fire fluid dynamics[1]. The naive algorithm uses a kernel to simulate convection, diffusion, and cooling of heat. Described in more detail by Joakim Hårsman[2]. Also see working demo of the OG fire algorithm by Justin Greisiger Frost[3]While canvas + CPU gets surprisingly good performance, this effect would probably run much faster on the GPU. On mobile, this version is sized to work better: https://fx.leftium.com/fire-plasma?standardSize=0&text=LeIn my improved version, flames "lick" the bottom of the floating text. This is my favorite part. It was totally unexpected and just emerged from the algorithm.

Show HN: NoSuggest – Watch YouTube without the recommendation algorithmhttps://www.nosuggest.com/NoSuggest is a quiet act of resistance against YouTube algorithms always trying to pull you into a loop of unlimited videos in turn into unlimited screen time. With unending side cards of videos, auto-play, what's next suggestions, YouTube shorts and notifications, users will be doom scrolling for many hours in a day.I faced the same problem. Acknowledging that, not all content in YouTube is bad. There are educational videos, genuine news contents without political bias which is very hard to find outside YouTube and many other good relaxing, entertainment stuff.NoSuggest lets you only follow the YouTube channels you like and removes all types of recommendation YouTube has. So you don't waste time on watching things which you never wanted to watch anyways.UI is very simple. You add your favourite channels in "Channels" tab and latest 5 videos per channel excluding shorts would appear in "Feed" tab. "Search" tab is to search for specific videos to watch and "Saved" tab is to bookmark any

I Replaced My AI Agent's Flat Fact Store with a Graph Databasehttps://news.ycombinator.com/item?id=48383578# I Replaced My AI Agent's Flat Fact Store with a Graph Database and It Runs in 85MBI've been building LocalClaw, a local-model-first AI agent framework running on personal hardware through Ollama. No cloud, no API costs. A few weeks ago I posted about the router/specialist architecture. A lot of people asked about the memory system so here's that.## The ProblemStarted with a JSONL fact store and embedding similarity retrieval. Simple enough until it wasn't. After a few weeks of real use I had 14 near-duplicate facts about the same topics from different sessions. Layered dedup on top of dedup and it still wasn't clean.The bigger problem was relationships. "Peter works at DevMesh" and "DevMesh is building an outreach platform" were two separate embeddings. You could retrieve each one but you couldn't traverse from one to the other. No multi-hop. No fact evolution. Old facts and new facts coexisted with no signal about which was current.Four iterations on the flat store later I accepted
