Math factoid of the day: 54

Thursday 16 June 2016

54 can be written as the sum of three squares in three different ways:

7² + 2² + 1² = 6² + 3² + 3² = 5² + 5² + 2² = 54

It is the smallest number with this property.

Also, a Rubik's cube has 54 colored squares.

Loudest guy in the room

Sunday 5 June 2016

I just got back from PyCon 2016, and it was a giant summer camp love-fest as usual. But I've been thinking about a subtle and unfortunate dynamic that I saw a few times there.

In three different cases, I was with a group of people, and one person in particular had a disproportionate amount of air-time. They were different guys each time, but they just had a way of being the one doing more talking than listening, and more talking than others. In some cases, they were physically loud, but I don't always mean literally the loudest.

These weren't bad people. Sometimes, they were explicitly discussing the need to include others, or improve diversity, or other good impulses. They weren't trying to dominate the space, and they might even be surprised to hear that they were.

But I found myself cringing watching their interactions with others. Even when they thought they were being encouraging, I felt like they were subtly pushing others aside to do it. Keep in mind, this was at PyCon, one of the most explicitly inclusive places I frequent.

I'm a successful white guy, so I know it can be very easy to slip into the alpha male stance. Sometimes people expect it of me. It can be hard to tamp down the impulse to hold forth, letting others have the spotlight. But it's important, and a good exercise for yourself. It's fine to be able to be at the front of the room, but you should be able to turn it off when needed, which is more often than you would think.

Sometimes, this was in a men-only setting. It's great to be aware of the gender gap, but there are other kinds of gaps to consider also: non-native speakers, introverts, beginners, outsiders of various sorts. There are lots of reasons people might be quiet, and need a little room.

Ask questions instead of making statements. Stay quiet, and see what happens. Listen rather than speak. Even when it seems no one is going to say anything, wait longer than you are comfortable. See what happens. Leave space.

Next time you are in a group of people, look around and try to figure out who is the loudest guy in the room. If you aren't sure, then maybe it's you.
