Which Steam badges can be currently obtained without any game cards?

By looking here and here you can see that the non game dependent are:

• The Community Leader badge
• The, so far, 15 Years of Service badges
• And the Gem badge

Plus some other ones that are impossible to get because they are either only earn-able during a limited time, or are for valve employees, translators or mods.

I got 100+ Badge - Power Player, After I bought 100 games on steam.
