What we'd post if Twitter wasn't six feet under.

  Deque University training is a great accessibility resource. I paid for the full course, which was like £350 back in December.

  One gripe though — although the accessibility principles are still solid, some of the content is wildly out of date. I mean I was watching TWENTY YEAR OLD videos!

  Was fetching like counts for every blog post on the homepage, one Redis request per post. Fine for two posts, not fine for two million.

  // before: one round trip per post
  await Promise.all(slugs.map(s => redis.get(`likes:${s}`)));
  
  // after: one round trip, full stop
  await redis.mget(...slugs.map(s => `likes:${s}`));

  mget fetches all the keys in a single call. The latency you pay once total, not once per item. Pretty obvious in hindsight to be fair.
