Show HN: SolidPing — open-source uptime monitoring, agents inside your network https://ift.tt/WHzVDhx

Show HN: SolidPing — open-source uptime monitoring, agents inside your network SolidPing is a single Go binary, AGPL-3.0 — 40 check types, status pages, incidents, on-call escalation, and sub-minute intervals that aren't paywalled. I loved Better Stack, and then the free plan kept getting thinner. What finally pushed me over: incidents used to get one Slack thread each, so an outage lived in one conversation instead of a stream of disconnected messages. That went away. I wanted it back, so I built my own. The part I'd most like torn apart is the agents. You run one inside the network you want watched and it dials out over a WebSocket, so there's no inbound port and no firewall hole. On first start it generates its own keypairs and keeps the private halves — Ed25519 for identity, an X25519 (age) recipient that the server seals check credentials to. So the credentials for a private check are encrypted for that agent, and the server storing them can't read them. All of it is open source: the agents, WhatsApp alerts, SSO, every check type. Nothing held back for a hosted edition. Self-hosting is genuinely easy, and I depend on it, https://ift.tt/mXesWVc is a second SolidPing running on fly.io that watches the cluster hosting the first one. A monitor that lives inside what it monitors isn't a monitor. I've maintained a small Go FTP server library for 10 years (github.com/fclairamb/ftpserverlib), so open source isn't a marketing decision here. Demo, no signup: https://ift.tt/PCtVA1j Source: https://ift.tt/sWykewL What I want is UX feedback and missing features — where the interface gets in your way, what you went looking for and couldn't find, what would have to exist before you'd run this instead of what you run now. Please be blunt. "Nice project" teaches me nothing. https://ift.tt/gRAOHK6 September 11, 2026 at 01:48AM

Show HN: Foldelight – the iPhone Duo folding effect the MacBook was owed I know the effect makes more sense on the iPhone Duo because of the dual screen, but I wanted something similar on the MacBook: the lid looks like a portal to the real screen. The only app I found that does this charges for it, so it felt like a good thing to ask Astra to build, and I made it OSS. Visual improvements or feature ideas are welcome. https://ift.tt/ZN4KTPU September 11, 2026 at 01:59AM

Show HN: AgentPulse – Claude Code and Codex status in tmux https://ift.tt/qFulHWU

Show HN: AgentPulse – Claude Code and Codex status in tmux I use Claude Code and Codex every day, often across several tmux panes. I kept switching windows to check which agents were still working and which needed an answer. I built AgentPulse so I could see that at a glance. It is a TPM plugin that uses lifecycle hooks to show working, waiting, idle, and interrupted states. It adds indicators to the window list and pane borders, with an optional popup and sidebar for jumping between agents. It works with your existing tmux theme. Because it is tmux you can customize it the way you want and optimize your workflow. This is an early version that grew out of my own setup. How do you keep track of agents in tmux? I would like to hear what would make this useful in your workflow. I know herdr exists, but couldnt leave my tmux setup. https://ift.tt/shCOKDV September 8, 2026 at 11:41PM

Show HN: Compute Polynomials Twice as Fast https://ift.tt/bSv7xrg

Show HN: Compute Polynomials Twice as Fast A few years ago my coauthor and I was wondering if we could reduce the number of multiplications used for hashing algorithms. We had a construction and a 100 page proof, but we were not 100% sure it was correct. Now we have a full Lean proof, so we decided to publish it. I made this website to make it easy for anyone how has polynomials to evaluate to see how it would be done using our method, as well as a number of previous approaches by Knuth and others. https://ift.tt/ltO1ZTy September 8, 2026 at 10:53PM
