My First Pair Of Nice Shoes
Back in high school, I was in a business club called DECA. We ended up in Louisville, Kentucky for one competition. I won, and that is still one of the better moments of my life.
My Message to "Leftover Women"
I just watched this video about “leftover women” in China, and it was one of the saddest things I’ve seen all year.
New Vocabulary For New Ideas
Michael Spivak once said that the definitions in math should be hard and the theorems should be easy. This is because the definitions are benchmarks for different levels of abstraction. Theorems are essentially chaining definitions together to get new definitions.
One Year of Programming
It’s been a year since I started learning programming. In that time, I went from not knowing what HTML was to doing machine learning and learning type theory and burning too many hours getting my mail to work in the terminal.
Where Programmers Beat Mathematicians At Their Own Game
I recently read this debate on StackExchange.
The Power of a Certain Counting Argument
The reason that bijective functions between sets imply that those sets are of the same size is because of a generalized version of a counting argument. If a function is injective, its target must be at least as big as its source, or else there isn’t enough “room” for points to map uniquely (google “Pigeonhole Principle”). For surjectivity, the target must be smaller or equal to the source because otherwise the function can’t fully cover the target since the target is too big. Each point in the source can only cover one point in the target. So if a function is to meet both, the sets must be less than or equal to in size as well as greater than or equal to in size. this means that they’re of the same size.
Surprisingly effective writing autocomplete in vim
It bugged me that vim’s autocomplete was giving me useless autocomplete while I was writing the draft to another blog post. So I decided to fix it, which turned out to be pretty trivial.
The Origin Of The Word "Thing"
It comes from the Old English word for a meeting place, and the Icelandic Parliament is called the Althing (literally: ‘all-thing’), and it’s been around over a 1000 years, which is pretty incredible.
Quote About Finding Flaws In Arguments
“As ever, if you want to find the weak point in an argument, look out for words and phrases such as”clearly”,”obviously”, or”it is easy to see that”. Often they indicate the place that the writer is not quite 100% sure about.”
Thoughts On The Future of Many Jobs
This post only says things that are pretty well covered elsewhere, so I’ll just give my thoughts and let you look for evidence/justifications.
A Niche For The iPad Pro
The iPad Pro has been marketed as a laptop replacement. I don’t know anyone who thinks it can do that, at least not yet.
A List Of Books I've Read So Far
These are all the books in my
calibre library tagged as “read”.
calibre makes it easy to get this information out of my
library in a computer-friendly format.
Programming languages as a hobby
It’s odd to say this, but recently I’ve started reading programming language papers as a hobby. It’s actually rather depressing as it’s only reinforced the massive disconnect between engineering in practice and current computer science research. Isn’t it frustrating to see loads of good ideas just ignored for a variety of reasons, from opaqueness to poor marketing?
What Wikipedia Means To Me
Wikipedia 15 wouldn’t allow me to post a long story, so here it is
Woes Of The Power User
Being a power user is almost always synonymous with saying you’re hard
to please. Which isn’t necessarily wrong. I use
mutt not because I
like it, but because it sucks less than everything else I’ve used.
Sounding smart is really easy. Being smart, as far as I can tell, is the result of a hell of a lot of mental discipline.
