90d22f643f Support dictionary.md
Back when I owned an iPhone -- before I switched (mistakenly and thus
temporarily) to Android -- I had a note for each year's newly learned words. As
I am condensing as many of my documents as possible into my briefcase, I decided
it is time for including a dictionary.

I can still record words on my phone, and then I can transfer them to this
document.

2a44b26630 Create //todo-lists
In the beginning there existed only a generic //org directory... This directory
was generic enough to include any .org file regardless of its purpose, but
specific enough to disallow membership of other worthy files of the Markdown
ilk.

Then came the //playbooks directory, which robbed //org of most of its
inhabitants...

In the interim various .md and .org TODO lists existed scattered across the
landscape of the monorepo... some existed in far-away, exotic lands like
"travel-histlist"... These fractious tribes shared much in common with their
distant relatives, but the superficial differences granted the simple-minded,
draconian filesystem license to prevent them from mingling.

Then one day the monorepo had a new visitor: //todo-lists.
//todo-lists restored order to the monorepo, uniting all of the fractious
documents under one roof.

.md and .org files held hands and sang Kumbaya around a blazing fire for the
first time in history. All was well, and all were happy.

c6106f7884 Create //playbooks
I'm particularly excited about this idea. As I was reading Graham's "Erase your
darlings" blog post, I had an idea: I should have playbooks at the root of my
monorepo.

I can have playbooks for the following:
- How to install NixOS
- How to build GCR images from Nix expressions
- A collection of miscellaneous shell commands (e.g. "how to kill a process by name")
- What series of steps should I follow when I receive a paycheck

I already keep README's at the root of each package, which I think is where many
of these instructions belong. Other tutorials that I write for myself that do
not belong to any package can go in //playbooks. I also will host my personal
habits in //playbooks since habits are a bit like playbooks for life. Let's see
how this idea ages as the caffeine wears off...

5add8ddc13 Move monzo_ynab into //tools
Optimizing is difficult: I like flat hierarchies because I don't like
directory-hopping, but I also would like a cleaner root for my mono-repo. Bombs
away!

Well it's that time again, folks: spring cleaning!

Here I am musing about a few things that bother me:
- Should I use kebab-case or snake_case?
- It feels ~confusing to have //tools and //utils. What a //projects? Isn't
  everything a project? *sigh*

0f1146cc4c Partially complete the "Basic Libraries" chapter exercises
I was instructed to benchmark these functions, but I couldn't get the
benchmarking library to run using Nix -- although I'm *sure* it's
possible. Unfortunately the book recommends using `stack`, which I couldn't
reproduce.

3665ea457b Partially complete some of the exercises for Composing Types
I believe there are two exercises sets in the "Composing Types" chapter. Here
are *some* of my answers so far...

I'm having trouble implementing Foldable for Compose. I was able to implement a
version of it by adding the (Functor f) constraint to the instance signature,
but I think I cheated.

I will revisit these problems as well as the earlier exercises later.

eb1af216cf Clear $NIX_PATH
Ensure that $NIX_PATH is empty using a .envrc file. nix.dev considers references
to <nixpkgs>, <briefcase>, <depot>, <unstable> to be an anti-pattern because it
hinders reproducibility by introducing an implicit environment.

This repository is chock-full of references to
<{nixpkgs,unstable,briefcase,depot}>, so right now everything is broken.

155dff562a Impl part 3/3 for Memo
Refactor the caching policy for the Memo by evicting the elements that have been
the least-recently-accessed.

Python's heapq module default to a min-heap. By storing our heap elements
as (UnixTime, a), we can guarantee that when we call heappop, we will get the
element with the lowest UnixTime value in heap (i.e. the oldest). When we call
heappush, we use (time.time(), key) and these values -- by having the largest
UnixTime, will propogate to the bottom of the min-heap.

a8b3a2d3c0 Support part 2/3 for the Memo problem
Bound the size of the memo by creating a BoundedQueue. Whenever we add elements
to the BoundedQueue, we remove the oldest elements. We use the BoundedQueue to
control the size of our dictionary that we're using to store our key-value pairs.

ee1aeee5f8 Complete exercises for Reader and State chapters
It's beautiful how State is just Reader that returns a tuple of (a, r) instead
of just a, allowing you to modify the environment (i.e. state).

```haskell
newtype Reader r a = Reader { runReader :: r -> a }
newtype State s a = State { runState :: s -> (a, s) }

fa4eb2c61b Remove auth from Bitlbee
I'm having trouble getting PAM auth to work, so I'm temporarily disabling it.

TIL that I can use the following to verify that PAM is properly setup for a
program (e.g. `bitlbee`).

```
pamtester -v bitlbee $(whoami) authenticate
```

...but despite this succeeding, I still cannot use the `identify` command in
`bitlbee` to successfully authenticate. It just tells me "Incorrect password"
even though I'm providing it the same password that I type when doing the
`pamtester` command from above.

Computers!

of many in that direction.
