happy new year, all. i’ve barely had time to absorb new music or artists in 2020, because mostly i’ve been listening with ash, and all he wants is the Grease soundtrack over and over (and over. and over). but here’s a little list of my top ten. ready?

1/ Here are my notes from @robertwrighter's book - Nonzero: the logic of human destiny. I enjoyed the book very much.

The basic premise of the book is that history has a direction which favors co-operation and non-zero sum games, and that causes an increase in complexity.

2/ Starting from the first replicating molecule which co-operated with an outer layer to form first proto-cell, evolutionary and cultural history is full of examples where two entities come together to survive and progress a lot more than they would have done individually.

3/ This co-operative entity fares much better than two individual entities because of specialization. If two entities are in the same boat - that they win together or lose together - then trust is implicit.

4/ In a non-zero sum game, trust causes entities to focus on what they do best.

For example, eukaryotic cells - the ones animals and plants have - emerged when two proto-cells merged, and one took the role of energy generator (mitochondria), the other specialized in protection.

5/ Some scientists believe that even nucleus in a cell is a result of an early cell merging with another cell.

So M&A is not a recent phenomena, entities have been merging because of common interests ever since life started.

The Calvin and Hobbes comic strip ended 25 years ago, so let’s celebrate a New Years treat by analyzing it! Awhile back I had a students annotate structures in every C&H strip, so we have data on the whole thing. As Calvin says: let’s go exploring! 1/ https://t.co/GAm45Ni1m5

An interesting feature of this strip is that Watterson took a few sabbaticals during its run, and came back with more artistic freedom. So, I’ll focus here on how a few aspects of the strip change over time. Here’s what every panel per strip looks like (all 14,712 panels!) 2/

Let’s start with storytelling. Overall, the strip shifts to becoming more visual and multimodality balanced in meaning over time. In this graph, higher numbers mean more meaning carried by pictures than words (0=balanced) 3/

You can also see this in the overall increase of wordless panels across strips. Interestingly, you see the same trends for both daily and Sunday strips, suggesting broader shifts in Watterson’s storytelling inclinations 4/

The amount of words also changed. The strip steadily got more wordy in the first half of its run, but then started decreasing again as it shifted to visual meanings 5/

A children's book explanation of what's happening:

1. If you are "smart money" you are allowed to take your $1 and leverage it up to $15+

2. You can now buy $15 of stock AND if you promise to short companies, you can short $15 of stock as well

3. In finance language, this means that you are $30 "gross" ($15 of longs + $15 of shorts) but $0 net (+$15 of longs -$15 of shorts). This makes everyone feel good because it feels like you are taking zero risk...but in reality, your $1 is exposed to $30 of risk.

4. Now you go around and tell your friends about both your longs and your shorts and when you do it at a restaurant vs on Reddit, its called an "ideas dinner".

5. You also publish your longs on a quarterly lag via an SEC rule. You don't have to tell anyone about your shorts.

6. Now the less cool people who weren't invited to the ideas dinners, start copying your longs based on your report.

7. You realize that publicizing your shorts is also a good idea so instead of only selling stocks, you also BUY options (puts) which has to be reported.

8. Now everyone can see both your longs and your shorts and if you have a hot hand, you can likely predict that the cool people from the dinner as well as the less cool people monitoring your filings will copy you.

9. But then an outsider notices that the math is way off!

In the shadowy corners of the shortwave spectrum lurk the Numbers Stations: strange radio broadcasts of mysterious blocks of numbers in creepy monotone voices!

It's actually an old form of spycraft which is still in use today. And as it's #WorldRadioDay let's take a listen...

A Numbers Station is a type of one-way voice link for sending information to spies in foreign countries.

Operating on Short Wave radio bands they transmit a secret code of spoken numbers. Use of Numbers Stations peaked during the Cold War, but some are still operating today.

Numbers Stations are operated by various national intelligence agencies. At set times on a pre-arranged frequency a musical tone is played, followed by a speech synthesised voice reading out blocks of numbers. To most listeners it sounds both creepy and meaningless.

However to spies it can be vital. The numbers can be decoded to reveal a message, provided the spy has the right One Time Pad (OTP) - a random number key that is only used once before it is destroyed. OTP encryption is impossible to break if done correctly.

Why broadcast your secret message on Short Wave? Because it can be picked up across the globe. All a spy needs is a shop bought SW radio, a pencil, and the correct One Time Pad and they - and only they - can decipher the message. No complex kit is required.

I don't often promote myself on here, but I should. I have done some things that I am proud of. So here is a thread of episodes from @OurTurnPodcast that I contributed a segment and/or co-hosted. #RPG #podcast

Here is one of my very first contributions, a segment about one of my favorite RPGs of all time: 13th Age. @13thAge I still love it, and I have hacked the system to run other genres (ex. Star Wars: The Old Republic). Give it a try

One the one-year anniversary of @OurTurnPodcast, I did a segment about Session Zero for RPGs. I love being a part of Session Zero in any #RPG, both as a GM and
