Hello HN. I built this mostly to monitor the things I host myself. I know it&#x27;s nothing too exciting.Anyway, the TL;DR is: Create an endpoint, and if your script&#x2F;cronjob fails to regularly ping it, you get notified (by email or ntfy). E.g.:<pre><code> 0 * * * * .&#x2F;script.sh &amp;&amp; curl -fsS https:&#x2F;&#x2F;sigabrt.dev&#x2F;pulse&#x2F;&lt;id&gt;&#x2F;beat
</code></pre>
It also has an SSH TUI which is currently experimental and read-only, mostly because I&#x27;m not sure whether it is actually useful or just a gimmick :):<pre><code> ssh sigabrt.dev
</code></pre>
To use it, simply add your SSH public key in your account settings.Yes, there are services like this already, and this is minimalistic by comparison. Feedback is welcome.

Hello HN!I&#x27;m relaunching Radius [1] - far too long after the original Show HN [2] (I&#x27;ll blame the day job for that).Radius started out from my frustration with not knowing what was going on around me. The initial plan was to &quot;show all and every type of event&quot; from big to small, but over time I narrowed the focus to communities, groups, events, and helping people connect through them.The initial Show HN gave me 150+ comments (surprising, looking back, given how terrible the plain Bootstrap UI was...) with a huge amount of useful feedback and feature requests. I&#x27;ve spent the time since then working through that, along with additional requests from groups using Radius, and it finally feels ready for a proper relaunch.I&#x27;ve also recently added &quot;Activities&quot; [3] - which are lightweight events, independent of groups, intended to help people find others to do things with - for example:&gt; John is going for a cycle and a coffee in New York at 10amPeople can join and vote for a time that works for them.I&#x27;ve got a bunch of ideas for where to go next with this, including things like open sourcing and federation, but those are for another day!Any feedback would be greatly appreciated!P.S. it&#x27;s built with Ruby on Rails, for those interested. I highly suspect it would have taken me 2 more years to get to this point without Rails![1] <a href="https:&#x2F;&#x2F;radius.to&#x2F;" rel="nofollow">https:&#x2F;&#x2F;radius.to&#x2F;</a>[2] <a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=40717398">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=40717398</a>[3] <a href="https:&#x2F;&#x2F;radius.to&#x2F;documentation&#x2F;activities&#x2F;post-an-activity" rel="nofollow">https:&#x2F;&#x2F;radius.to&#x2F;documentation&#x2F;activities&#x2F;post-an-activity</a>
