Minimum Wage, Expressed in Uselessness of Pennies

The following is a tabulation of minimum wage, except in a manner to point out how badly useless and economically inefficient the penny is. This is a chart of how long you can spend dealing with a US penny before you have spent more time dealing with it than the time-worth of a penny at minimum wage.

The Four-Colorability of the World: Addendum on Planarity

After presenting my conclusions in my previous post on the four-colorability of the world to several friends and friends of friends, we pondered the question of whether the map of the world’s countries is planar. It is in fact not: consider the induced subgraph of (that is, consider the connections among) Turkey, Georgia, Armenia, Azerbaijan, Iran, Turkmenistan, Kazakhstan, and Russia.

Trick-Taking Card Games

Consider one round of a four-player trick-taking card game with no trumps and no breakages (for instance, if hearts did not need to be broken in Hearts). (That is, players must follow suit of the first card played in the trick unless they can’t.) How many of the 52! orderings of cards represent a legal order in which the cards could be played in the round?

To provide examples, any ordering that starts


is illegal, as [6♣,K♣,Q♢,10♣] constitutes the first trick, and thus the player who played the K♣ starts the next trick, and thus the player after them has broken the rules as they clearly have at least one club (the J♣ they played this trick) that they did not play last trick (where they played a Q♢), but


is, as it turns out in this case the four parties were each dealt all the cards of one suit, and thus subsequent players will never be able to follow suit of the first player.

Here are some ideas for extensions: have a trump suit, have a breakage rule, have both, solve this for Napoleon.

How I Generate My Passwords, and Why, Fuck You Apple

What is much more problematic than using a weak password is using the same password in multiple places.

There’s a gigantic issue with using a new password for each site that you go to, though: you have to memorize that many passwords. You could use a scheme where you use the same base password and then append the name of the site to the end, but that’s really not more secure than just using the same password in each site.

You could decide to use one of those password managers that exist out there. Personally, I find myself unable to believe that I could just trust some external entity with all my passwords and have an expectation they’re all alright. Oh wait, I’m not even paranoid.

Here’s how I generate my passwords. This scheme is actually memorable, and actually produces significantly different passwords.

Here’s all you memorize to cover all of your websites you care about your password in: a string, a hierarchy, and a function.

(Also, there are definitely places you don’t care about your password. Some of them send you your password in plaintext. Don’t even bother making a secure password in those cases.)

1. The String

Any string of length that’s at least some moderately large number.


, for example, is an excellent string. It doesn’t matter that you don’t understand any particular patterns in the string, because there’s only 12 characters in it, and you can easily memorize just one string of 12 random characters.

Death to Coinstar

A lot of people consider big banks evil. Why do people consider big banks evil?

Many like to express their frustrations towards financial institutions as places that don’t actually give material good to the world, and make money off of money, or often phrased as “making money off of nothing” or “selling a nonexistent product”. (Like churches.) Another issue people often take is the fact that banks make money off of people with unfortunate or exploitable financial situations.

If you hate what there is in this world that makes money off of nothing, then there’s another institution you might not have thought much about that exhibits this banklike property: Coinstar. Like banks, Coinstar makes money off of your money and gives you nothing else in return. Coinstar is as evil as big banks.

As evil? Pardon me; my apologies to big banks. Banks do give you something: they give you a relatively secure place to put your money and saves you a lot of the inconvenience of dealing with large amounts of money, and they allow you to take out loans so you have the money to do things that would hopefully be nice things to have but for which you for now don’t have the financial resources for but will more likely later, although how much of a nice time banks have with these loans is much of why people hate them. Coinstar actually literally just makes you pay a surcharge to be able to use money you already had.

But wait, doesn’t Coinstar make your coins more useful and less heavy to carry? Yes, what you’re buying with Coinstar is convenience, but this is convenience you almost certainly don’t need, because the denominations of change that actually make you go to a coinstar machine—pennies and nickels—are denominations of money for which the major issue with the pecuniary worth you are throwing away by using the Coinstar machine is not even the Coinstar surcharge but the worth of your time traveling to the machine to get rid of them. (Face it, if all you had to deal with was quarters, you wouldn’t use a Coinstar machine. Quarters are actually still useful in this age, though maybe not for long. They’re still not ridiculously inconvenient at laundry and vending machines.)

If you make federal minimum wage in the United States ($7.25/hour), then you have lost more than a penny’s worth of time if you took 5 seconds to deal with a penny. You’d think that given this the United States would’ve just gotten rid of the penny by now. Hahahaha. Guess why they haven’t?
