Handwriting for math etc

May 28th, 2018
tech, math  [html]

I don't have very tidy handwriting, and for most things this is fine: there's enough redundancy in language that it will be clear from context what is a t and what is a +. When writing calculations, however, there's often a lot less redundancy and so it's more worth it to make sure distinctions aren't being lost. One way to handle this would be to have clean handwriting overall, but what I do instead is use glyphs that are more robust and remain distinct even if written poorly. [1]

Here are what I do with some tricky glyphs:


i j t + l 1 I 2 z 7 ;

It's nice if these are clear to other people, but the main goal is for them not to be confused with each other. Things to help this:

  • i includes a right hook
  • j is normal
  • t includes a right hook
  • + is normal
  • l is loopy/cursive
  • 1 is a straight line
  • I has top and bottom lines
  • 2 is normal
  • z has a cross
  • 7 has a cross
This lets me write thing like:


(zt + 2ij)/7Il

and still be able to read back what I wrote. This is also something I need when transcribing whiteboard coding interviews at work: [2]


for (int j = i; j < t + z; j++)

You might notice that I don't use this for the i or t in int. It's just for variables.


[1] I don't think this is original to me, but it's also something I picked up gradually as I realized that certain forms were more reliable.

[2] Yes, candidates write code on whiteboards, we transcribe it on paper, and then we type it into a computer for others to review. Someday candidates will write on laptops, I guess, but it was weird that we were doing it in 2010, and we're still doing it in 2018, so who knows.

Strong stances

I. The question of confidence Should one hold strong opinions? Some say yes. Some say that while it’s hard to tell, it tentatively seems pretty bad (probably). There are many pragmatically great upsides, and a couple of arguably unconscionable downsides. …

What do executives do, anyway?

An executive with 8,000 indirect reports and 2000 hours of work in a year can afford to spend, at most, 15 minutes per year per person in their reporting hierarchy... even if they work on nothing else. That job seems impossible. How can anyone make any im…
