Show HN: ArkWatch – Uptime monitoring with zero dependencies
I'm a solo dev, and I got tired of signing up for monitoring services that require installing agents, browser extensions, or wiring up Slack/PagerDuty just to know if my side project is down.
So I built ArkWatch: a free uptime monitoring API with zero dependencies. No SDK, no npm package, no webhook setup. Just curl + your email.
One command to start monitoring:
curl -X POST https://watch.arkforge.fr/monitors \ -H "Content-Type: application/json" \ -d '{"url":"https://yoursite.com","email":"you@example.com"}' That's it. Your URL gets checked every 5 minutes. If it goes down, you get an email. No dashboard to check, no account to manage, no vendor lock-in.
It also has an AI layer (Mistral) that summarizes what actually changed on a page – useful for tracking competitor pricing or changelog updates. But the core use case is dead-simple uptime alerts.
Stack: Python/FastAPI, hosted on Hetzner EU. Free tier: 3 URLs, 5-min checks. Paid starts at €9/month for more URLs and faster intervals.
I'd love feedback from HN – especially on what you'd want from a zero-dependency monitoring tool. Try it, break it, tell me what's missing.

Discussion: Seedance-style AI video generation workflows
I recently came across a site called Seedance 2: https://seedance2.tech/
It seems to be exploring a different angle of AI video generation, focusing more on rhythm, motion, and visual continuity rather than long-form cinematic storytelling.
I’m curious what people here think about this direction in general: - Does a rhythm- or motion-focused approach to AI video feel genuinely useful? - How does this compare to current AI video tools in terms of control and expectations? - If you were to use an AI video generator, what kind of control would actually matter to you?
Not affiliated, just interested in discussing where AI video generation workflows might be heading.

Subtle thermal factors I didn't expect when testing high-power LEDs
I’ve been experimenting with high-power LEDs in open, non-commercial setups to better understand real-world thermal behavior outside finished products.
What stood out was how strongly non-electrical details affected stability: – mounting pressure – interface materials – real airflow paths versus assumed ones
Electrically everything stayed within ratings, but long-term thermal behavior varied more than expected.
For those who’ve worked with power-dense hardware: what thermal assumptions turned out to be wrong in practice?

Show HN: CPL – A categorical programming language that runs in the browser
CPL is a programming language based on category theory, originally designed by Tatsuya Hagino in his 1987 PhD thesis at the University of Edinburgh. It has no built-in data types — products, coproducts, natural numbers, and even exponentials (function space) are all defined by the user using F,G-dialgebras.
In this release, CPL now runs in your browser via WebAssembly with no installation required. I've also added tutorials in both English and Japanese.
