  1. Klaus
    Great help to review books

    I imported my kindle highlights, as many others. Now I daily review some highlights (thanks to a dashboard, I am motivated). And where I didn't create highlights, as I only listened to the audiobooks, I get the highlights from others. It also allows to create beautiful quotes. It adds the book cover and matches quote and background with colours found on the book title! Really nice!

  • Exporting Mac OSX Book Highlights into an Obsidian Vault or Markdown Files
    The only highlights that Readwise retrieves semi-automatically are from the books I buy from Kindle, by going into the Readwise app and clicking a button.

  • Show HN: I combined spaced repetition with emails so you can remember anything
    Readwise also has this feature. I get a daily email with a random assortment of highlights that have been pulled in from multiple sources (Reader, Notion, Kindle, etc.) The product benefit in their case is that it's kind of like Zapier, but for notes. https://readwise.io/. - Source: Hacker News / over 1 year ago

  • AWS us-east-1 outage: How Ablyโ€™s multi-region architecture held up
    During this weekโ€™s AWS us-east-1 outage, Ably maintained full service continuity with no customer impact. This was our multi-region architecture working exactly as designed; error rates were negligibly low and unchanged throughout. Any additional round trip latency was limited to 12ms, which is below the typical variance in any client-to-endpoint connection, and well below our 40โ€“50ms global median; this is... - Source: dev.to / 10 months ago
