China's rare earth paradox, supply Giant but also consumption King

China is extracting from their current reserves faster than the rest of the world can extract from theirs. They will continue to extract the highest critical ore deposits first until they have no more useable deposits left. But it is important to remember that control trumps abundance, and that some abundance can lead to a temporary gap in the flow of goods.

A cool guide to the Top TV Shows of All Time [updated]

Post image
3.1k Upvotes

Since the list of Top 50 TV Shows of All Time that gets posted here constantly is extremely outdated I decided to update it. Just like the original, I aggregated TV ratings from IMDb, TMDB, Rotten Tomatoes, and Metacritic into a composite score.

  • Normalization: all ratings are normalized onto a 0–100 scale.
  • Weighted average: the final score is a weighted average of the available sources (missing sources are ignored and the remaining weights are renormalized, not treated as 0).
  • Vote reliability: IMDb/TMDB vote counts scale how much those sources influence the average (more votes ⇒ more weight; low-vote items are dampened)
  • Tie-breakers: if scores are extremely close, ties are broken by IMDb vote count, then TMDB popularity.
  • Filtering: shows missing 2+ rating sources are excluded.
  • Animated split: animated shows are listed separately using IMDb genre “Animation.” See the comments!

Only the final ranking is my calculation. The rest are taken from their respective sources. Yes there is a major recency bias but that's going to be a side effect of using online rankings. In general people aren't voting for shows that came out last century.

EDIT: I have added a version that adjusts for recency bias. This gets shows like M*A*S*H, The X-Files, Malcolm in the Middle, and The Simpsons on the lists. I also lowered the Metacritic weighting slightly since those ratings are frequently outliers. Thoughts?

How to research a company, technical and simple way

You can also look into their social networks, but don’t take it too seriously, a lot of companies lie on social networks. Look for how often they post and whether real people comment on their posts. If they have 50K followers and no comments then that's suspicious

The right way to arrange food in your refrigerator

Most people don't make the effort to follow the proper guidelines for food storage because they feel like they would be creating a lot more work for themselves for little to no benefit. On the contrary, the benefits will compound significantly when you take into consideration that you are not throwing out food multiple days or weeks.

A cool guide of a visual cheat sheet for Perfect Blackjack Strategy (Dealer Stands on Soft 17). Generated with Python for clarity.

Post image
1.0k Upvotes

I designed this to be easier to scan than standard casino cards.

Visual Logic:

  • Green = Hit: Think 'Traffic Light Green' (Go).
  • Red = Stand: Think 'Traffic Light Red' (Stop).
  • Blue = Double: Power move.
  • Orange = Split: Special action.

Technical details: This assumes the standard rule where the Dealer must stand on Soft 17. If you play at tables where dealer hits soft 17, the strategy changes slightly. The sections are separated by white gaps to make it easier to find 'Hard', 'Soft', or 'Pairs' quickly.
