Got my little app deployed last night. If you think Kamal + Hetzner is a replacement for Heroku then you really *really* have never understood the value of Heroku.
Deploys are quite fast now but setting up Kamal is like "so you start with an already drawn owl, now…".

Looks like X is juicing web visit numbers by opening a browser WebView in the background whether the user visits the link or not.
They've re-invented pop-under fraud (allegedly).

![Tell HN: X is opening any tweet link in a webview whether you press it or not
247 points by stillatit 10 hours ago | hide | past | favorite | 200 comments
Just saw the CEO of Substack celebrating traffic from X/Twitter shooting up thinking they stopped suppressing tweets with links[0]. Actually, this traffic is because now any time you open a tweet with a link, the in-app webview loads in the background, and displays when you press the link.
I run an ecom store that gets a lot of its customers from Twitter. I was also shocked to see my traffic double or triple overnight and thought the algorithm had blessed me and my business. Soon realized what was actually happening. Thought other traffic-monitors might appreciate this explanation.
Meanwhile Nikita Bier is pretending they never suppressed tweets with links to begin with, offering the alternative explanation: "a common complaint is that posts with links tend to get lower reach. This is because the web browser covers the post and people forget to Like or Reply. So X doesn't get a clear signal whether the content is any good"[1]. A bit of a rewriting of history since Elon and his mom both tweeted about how it wasn't fair to use his platform to promote other links/platforms, even banning people who shared profiles of other social networks (including Paul Graham for a period). They suppressed all links shortly after.
