938c1a4eb0 Start lorri with sytemd
Whenever possible, prefer starting things as systemd units instead of
instantiating them in ~/.profile and other dotfiles.

048b7867bf Add bin dependencies to wpcarros-emacs
I removed most of the packages that I install with `nix-env`. You can view these
with `nix-env --query`. This is one small step in a grander project to migrate
entirely to a declarative config managed by Nix.

c15a393112 Start lorri daemon in ~/.profile
This does two things:
1. Starts lorri daemon
2. Moves ssh-agent and docker daemon startup calls to ~/.profile

I'm still not entirely sure when ~/.profile is evaluated... I'd like to use
systemd to startup and manage these background services, but I currently don't
have a strong enough desire to do this.

0009ba2d71 Drop support for dkish
dkish was an idea to quickly create REPLs for all sorts of languages like
Haskell, Elixir, Clojure. I haven't used these, and if I started wanting these
with my newfound comfort with Nix, I think I'd reach for that instead.

52d284f59d Remove assertions that prelude/executable-exists?
I'm in the midst of transitioning onto a few new tools.

My previous workflow just used `nix-env` to install *some* packages. I didn't
have a prescribed methodology for which packages I would install using `nix-env`
and which ones I would install using `sudo apt-get install`. Sometimes if a
package would be available in my aptitude repositories, I'd use that; other
times when it wasn't available I'd use `nix-env`. One complication about being
on gLinux intead of NixOS is that some packages (e.g. nixpkgs.terminator) is
available via `nix-env -iA nixpkgs.terminator`, but the installation won't
actually run on my gLinux. In these instances, I would install terminator from
the aptitude repositories.

Then @tazjin introduced me to his Emacs configuration that he builds using
Nix. What appealed to me about his built Emacs is that it worked as expected on
either a NixOS machine and on gLinux (and presumably on other non-NixOS machines
as well).

A setup towards which I'm working is to own one or a few NixOS machines whose
configurations are entirely managed with Nix. On devices like my work machines,
which cannot run NixOS, I can build as much of the software that I need using
Nix and attempt to minimize the ad hoc configuration either with shell scripts,
python, golang, or more Nix code... it's clear that I still don't have a clear
idea of how that part will work.

For now, I'm adopting nix, nix-env, lorri, direnv, and weening off of aptitude
as much as I can. Things are a bit messy, but my general trend feels
positive. Stay tuned for more updates.

b47ca8b876 Support lorri
From what I currently understand, lorri is a tool (sponsored by Target) that
uses nix and direnv to build and switch between environments quickly and
easily.

When you run `lorri init` inside of a directory, lorri creates a shell.nix and
an .envrc file. The .envrc file calls `eval "$(lorri direnv)"` and the shell.nix
calls `<nixpkgs>.mkShell`, which creates a shell environment exposing
dependencies on $PATH and environment variables. lorri uses direnv to ensure
that $PATH and the environment variables are available depending on your CWD.

lorri becomes especially powerful because of Emacs's `direnv-mode`, which
ensures that Emacs buffers can access anything exposed by direnv as well.

I still need to learn more about how lorri works and how it will affect my
workflow, but I'm enjoying what I've seen thus far, and I'm optimistic about the
road ahead.

5df3bb4e40 Partition deepmind directory into two parts
Since I did not pass my one-site interview with DM, but I have been invited to
attempt again, I decided to partition this directory into two parts:

   earning the job.
2. part_two: Hosting the exercise that I will complete before my second attempt
   at earning the job.

fafabc6e4a Support OAuth 2.0 login flow for Monzo API
After some toil and lots of learning, monzo_ynab is receiving access and refresh
tokens from Monzo. I can now use these tokens to fetch my transactions from the
past 24 hours and then forward them along to YNAB.

If YNAB's API requires OAuth 2.0 login flow for authorization, I should be able
to set that up in about an hour, which would be much faster than it took me to
setup the login flow for Monzo. Learning can be a powerful thing.

See the TODOs scattered around for a general idea of some (but not all) of the
work that remains.

TL;DR
- Package monzo_ynab with buildGo
- Move some utility functions to sibling packages
- Add a README with a project overview, installation instructions, and a brief
  note about my ideas for deployment

Note: I have some outstanding questions about how to manage state in Go. Should
I use channels? Should I use a library? Are top-level variables enough? Answers
to some or all of these questions and more coming soon...

138070f3f6 Inherit parent's .envrc variables

1772408c39 Further support Monzo OAuth2.0 login flow
I'm now pulling the authorization code off of Monzo's request to my redirect
URI. I intend to use exchange that code for an access and refresh token. Once I
have these two items, I should be able to interact with Monzo's API much more
easily.

70034d4cb9 Begin supporting Monzo OAuth 2.0 login flow
What's done:
- Basic support of the client authorization grant stage of the OAuth login
  flow:
  - Open Google Chrome to point the user to Monzo's client authorization page.
  - Created a web server to retrieve the authorization code from Monzo.

What's left:
- Pulling the authorization grant (i.e. code) from Monzo's request and
  exchanging it for an access token and a refresh token, which can be used to
  make subsequent requests.

Unanswered question:
- Assuming this is a stateless app, where should I store the access token and
  refresh token to avoid the authorization flow. I'd like to avoid the client
  authorization flow because ideally I could run this app as a job that runs
  periodically throughout the day without requiring my interactions with it.

Some interesting notes:
- Notice how in the .envrc file, it's possible to make calls to `pass`. This
  allows me to check in the .envrc files without obscuring their content. It
  also allows me to consume these values in my app by using
  `os.Getenv("client_secret")`, which I find straightforward. Overall, I'm quite
  pleased to have stumbled upon this pattern - assuming that it's secure.

cce926d60f Remove KBDs supporting undesired Ergodox configuration
I mistakenly mapped one of my dual-function keys on my Ergodox to send Shift+CMD
instead of CMD. When some of my Emacs keybindings weren't firing, I noticed that
the key event they received was some like `C-S-s-<char>` instead of say
`C-s-<char>`. As a quick fix, I duplicated each of my keybindings that relied on
the CMD key to support Shift+CMD as well until I remapped the key on my
Ergodox. This morning, I remapped the Shift+CMD key to CMD, so I'm bidding adieu
to this code.

916e46d7ce Support script to download RFCs to my Kindle
Today I learned that you can email your Kindle files to read them using the
paperwhite display. I'm attempting to read RFCs, so after reading 1/4 of the way
through RFC6479 (on OAuth2.0), I realized that it might be easier to read on my
Kindle instead of on my computer screen. Out of this, rfcToKindle.go was born.

I'm not sure if I'd like to publish this or not.

5521db80b1 Attempt to debug xrandr behavior in display.el
Currently, after I connect my monitor to my laptop, I run `display/enable-4k`,
which will use `xrandr` to enable the display. The scaling of the enabled
display is not what I expect. So I've habituated re-running the same function,
`display/enable-4k`, which scales the display and meets my expectations.

What's strange is that if instead of running `display/enable-4k` the first time
from Emacs, I call `xrandr ...` from a terminal, this enables the display and
scales it properly on the first invocation.

I'm unsure how to explain this behavior. It's possible that a environment
variable is set properly in the terminal that isn't set in my Emacs, but this is
just a guess.

I'm going to using a different invocation in display.el that explicitly passes
the monitors dimensions. Let's see if that works.

6fd9947ec8 Re-write delete_dotfile_symlinks in golang
I'm currently quite unfamiliar with golang. As an exercise to help me onboard
onto golang, and as a proof-of-concept to see if golang is a viable substitute
for Python as a scripting language, I decided to port my delete_dotfile_symlinks
to golang.

In the process, renamed ./python -> ./scripts, which is a more accommodating
name for a directory.

837cfe07c7 Rename dotfiles -> briefcase
Renaming my mono-repo briefcase.

I first introduced this commit in master, but it introduced a bug where one of
two things would happen:

1. Emacs wouldn't start and would crash X.
2. Emacs would start but my keyboard wouldn't work.

I learned some valuable debugging skills in the process. Here are some of them:

When my keyboard was broken, I wanted to control my computer using my
laptop. Thankfully this is possible by using `x2x`, which forward X events from
the SSH client to the SSH host.

```shell
> # I'm unsure if this is the *exact* command
> ssh -X desktop x2x -west :0.0
```

Git commit-local bisecting. I didn't need to do a `git bisect` because I knew
which commit introduced the bug; it was HEAD, master. But -- as you can see from
the size of this commit -- there are many changes involved. I wanted to binary
search through the changes, so I did the following workflow using `magit`:

- git reset --soft HEAD^
- git stash 1/2 of the files changed
- re-run `nix-env -f ~/briefcase/emacs -i`
- restart X session
- If the problem persists, the bug exists in the non-stashed files. Repeat the
  process until you find the bug.

In my case, the bug was pretty benign. Calling `(exwm/switch "Dotfiles")` at the
bottom of `window-manager.el` was failing because "Dotfiles" is the name of a
non-existent workspace; it should've been `(exwm/switch "Briefcase")`.

There may have been more problems. I changed a few other things along the way,
including exposing the env vars BRIEFCASE to `wpcarros-emacs` inside of
`emacs/default.nix`.

The important part is that this was a valuable learning opportunity, and I'm
glad that I'm walking away from the two days of "lost productivity" feeling
actually productive.

edea127e07 Support building wpcarros-emacs
I'm using a Makefile until I can remember the command:

```shell
> nix-env -f . -i
```

This will install (i.e. `-i`) any derivations instantiated from the Nix
expression resolvable by `-f`. Ideally the incantation will look something like
this:

```shell
> nix-env -f '<universe>' -iA emacs
```

Informing `nix-env` to install all of the derivations created by the expression
at attribute `emacs` in my `<universe>` repository. For now two things are
preventing this:

1. `emacs` isn't an attribute in my top-level expression defined in the
   `default.nix`.
2. If I do add `emacs` as an attribute and call the above command, my usage of
   `readTree` results in `pkgs` missing `.lib` and a few other stdlib commands
   that are available in `(import <nixpkgs> {})`.

A fix for both of these should be forthcoming.

values of these hostnames.

Immediately impacted:
- .profile
- device.el

Not immediately impacted:
- configs/install
- configs/uninstall
- .ssh/config
- .zshrc*

* As a side note, I should stop supporting ZSH.

Using an .envrc file helps me DRY up some of my configuration. Ideally I should
only need to make changes to the .envrc file and then expect everything to work
as expected. Let's see how that goes.

bacaa0ca8a Add docker/cloud_run.nix
I'm attempting to setup my blog using the following:
- Google Cloud Run: I whitelist a docker image that packages my application and
then Google runs it "statelessly" (i.e. without persistence). The stateless part
should be fine for the time being.
- Nix: Using `<nixpkgs>.dockerTools.buildLayeredImage` to output docker images
from Nix expressions.
- Docker: Upload the output image from the Nix expressions and upload it to
Google Container Registry from which it can be run from Google Cloud Run.

Some helpful commands:

```shell
> sudo gcloud auth login
> nix-build ./docker/cloud_run.nix
> sudo docker image import ./result
> sudo docker tag <name> gcr.io/<google-cloud-project-id>/<name>:<tag>
> sudo docker push gcr.io/<google-cloud-project-id>/<name>:<tag>
```

I'm unsure if Google Cloud Run is my desired end goal, but it may help me
publish a blog faster than setting up a Kubernetes cluster, which is what I'd
ultimately like to do. Cloud Run should be cheaper financially and time-wise.
