Project Heimdall

Heimdall's All-Seeing Eyes — Heimdall sees and hears, all thanks to his extrasensory capabilities. His sight can extend across all Nine Realms, and he can see 10 trillion souls from the Bifrost Observatory. Asgardians call him from other worlds, such as Earth, Jotunheim, and Sakaar.

Honestly, the GTM strategy for Heimdall is a considerable concern. How are we going to do that?
Project Heimdall Locale Transition Strategy
Project Linguine

Implemented Login with Clerk
The useLocaleRedirect caused some problems when a user landed on Heimdall in a non-English locale context and logged in
- Clerk needs some initial load time, for example, 2s, for the Clerk Login SDK to load
- After logging in, conditionally loading <SignIn> caused an Error on Clerk, that rendering <SignIn> when users are logged in is illegal. Thus, Clerk was redirected to the default locale. This happened within the next 2 seconds when Clerk figured that it was logged in and when React was unmounting the <SignIn> widget.
- Because useLocaleRedirect sends to English by default, the original locale will be lost
- To get over this, I created two features:
  - Save to local storage on the user's locale
  - redirect within the useEffect hook (Warning: Cannot update during an existing state transition (such as within render). Render methods should be a pure function of props and state.)

Also used HOC to inject callback when <SignIn> gets dismissed. Do I have to do this? Really?

const withUnmountFunction = (WrappedComponent, onUnmount) => {
  return function (props) {
    useEffect(() => {
      return () => {
        if (typeof onUnmount === 'function') {
          onUnmount()
        }
      }
    }, [])
    return <WrappedComponent {...props} />
  }
}
```

```tsx
const SignInWithUnmountFunction = withUnmountFunction(SignIn, () => {
  setSignInOpen(false)
})

Created an MSA-style micro worker that will continuously fetch, load, and summarize HN contents!

I was very close to shutting down all small locales. It costs too much while driving me so little value. People are spamming the newsletter mailing list by enrolling in all lists. I thought all small locale lists were like that so far. But then... I found one Danish user.

This person was the only one on the Danish list.

But... it changed my mind. I was moved. Ok... I'll keep the small-medium sprachraums.

Every hour, the processor will:

For all newsletter that is
- non-deleted
- has a non-deleted subscriber
Get content from the web
Generate Summary
Send Email

Also, instead of having one newsletter that could be transformed into many languages, let's start with 30 different newsletters covering the same content. That is, separating the linguistic UI from the newsletter content. So in a Korean interface, you can go to Hacker News Japanese version and read the content accordingly.

iCalendar RFC 5545?
Cron notation?
