- Programming Bottom-Up: Benefits of writing reusable utility functions and
amassing a personal utility belt. Specifically how lisp makes this easier than
most or all languages.
- This Year We Can End the Death Penalty: Voting against the death penalty is
voting against the killing of killers *and* the killing of innocent people,
since some estimate that 4% of people on death row are in fact innocent.

Write a predicate that tests whether two films in a list of films can exactly
fill the duration of a flight.

As I mention at the top of the org file, I cannot rely on my web browser
informing me which of these essays I've read; it only shows me which of the
links I've clicked.

- Support command to open a dired buffer with wpcarro's $HOME directory for any
host defined in ssh/hosts.
- Support opening the current buffer with sudo privileges.

The command...
nix-build -A config.system.build.isoImage -I nixos-config=installer.nix nixos
...creates an .iso file in the ./result directory. You can then copy this onto a
USB and use it a custom installer...
cp ./result/iso/*-linux.iso /dev/sda
I needed an installer that used a version of the Linux kernel higher than the
one distributed on NixOS's website: 4.19.? -> 5.4.20+. My Acer laptop needed a
version of the kernel that supported its network controller: Intel 3168NGW.
TODO(wpcarro): Pin the nixpkgs git commit SHA inside of installer.nix.

I'm attempting to configure an old Acer laptop that I bought at a used
electronics store in Shepherd's Bush (~100GBP) as my server. I'd like to install
NixOS on it. The configuration.nix herein defines a starting point for the
configuration for that machine. It isn't currently working.
Troubleshooting and solutions forthcoming...

Write a predicate that tests if a given list of integers, zs, is a possible
interleaving of two other lists, xs and ys.
|
|
Write a function merging two sorted arrays into one sorted array.
|
|
I'd like to setup a NixOS machine that runs in my flat to host my blog and other
projects. For now it's a slow Acer running Manjaro Linux. I'm hoping that I can
install NixOS on it remotely over SSH. But first! SSH access...
I setup port forwarding from my router to this machine for:
- HTTP
- HTTPS
- SSH

InterviewCake asks "How would you handle punctuation?". Without precise specs
about what that entails, I'm supporting sentences ending with punctuation.
|

Wrote a function to reverse the words in a list of characters. A word is a
space-delimited strings of characters.
The trick here is to first reverse the entire string and then reverse each word
individually.

Every Tuesday I work from Google's 6PS office instead of BEL. I work from my
laptop, which often requires that I ssh into the desktop work station in BEL. I
have settled on a locally optimal workflow that I'd like to improve. To help
seek higher ground, I'm planning on using ssh.el to configure tramp and define
utility functions to lower my cost of exploring new workflows.
- Defines a function, `ssh/desktop-cd-home` that helps me quickly open a dired
buffer for my work station's home directory.
- Documents some variables that I set weeks ago.
- Requires ssh.el in init.el.

Until now my notmuch is usable but not almost always pleasurably so. For
example, when I reply to messages, notmuch warns that "Insert failed:"; when I
check Gmail, the reply sent... strange. After consulting with a fellow notmuch
user and Emacs disciple, tazjin@, I borrowed some of his notmuch configuration.
- notmuch is no longer warning about replies
- Replies do not include noisy email signatures
- I have an Emacs User-Agent header in my outgoing mail
- All of this and more...
|
|
I'm attempting to incorporate the beloved find-file-at-point function into my
workflow.
|
|
Add tag:unread to:
- direct
- broadcast
- systems
Additionally: I added "and not tag:sent" for direct because oftentimes I send
myself mail. Without that condition, my sent mail shows up in direct.

keybindings.el calls (require 'evil-ex), which I introduced in this commit...
0456a1c4b4405da2681296b2250681454637d80f
...calling (require 'evil-ex) loads evil. When evil is loaded before
evil-want-integration is set to nil, evil-collection writes to *Warnings* when
Emacs initializes, which I find noisy. This commit ensures the
evil-want-integration is set to nil before evil is loaded, which appeases
evil-collection and thus removes the warning message.
Bonus:
If you git checkout the previous commit, and attempt to run the KBDs...
- `SPC g s`: magit-status
- `s h`: evil-window-vsplit
...from a buffer whose major-mode is dired-mode, you should notice that the
above functions won't execute.
Strangely though, if you look at this commit...
37f8ca04f29ea9bf988b2277c42f3e264d7a89e1
...I fixed these issues. Well I introduced a regression when I added 0456a1c.
My current guess is that when evil-collection complains about
evil-want-integration, it is breaking the evaluation sequence of my init.el
file. wpc-dired.el is downstream from wpc-keybindings.el, which requires
evil-collection. Perhaps no modules required after wpc-keybindings.el are
evaluated after evil-collection warns about evil-want-integration. Even if that
assumption is wrong, what I do know is that this commit fixes the
evil-collection warning and restores the KBDs for dired-mode-map.
Here's to feeding two birds with one scone!

I'm finding myself running `pkill compton` offer. In the spirit of slimming down
my configuration, I'm dropping support for compton.
|
|
Support `systemctl` and `systemctl --user`.

Today I setup declarative gmail filters using some Google internal tooling. I'm
now adding labels to messages from Critique, Sphinx, Ganpati, "The Daily
Insider", messages sent directly to me, and more. These labels are applied
server-side.
On the notmuch, client-side, I'm support saved queries for these newly created
gmail labels.
|
|
I can already tag emails with `+` and `-`. Here I'm defining KBDs for moving
messages from my inbox into: action, review, and waiting. I'm also mutually
excluding messages in action, review, and waiting from inbox and vice versa.
I'm also supporting a "muted" tag for now; I'm still learning how to use notmuch
with email threads, but I'm hoping the "muted" tag will prevent future messages
in a thread from arriving in my inbox.

The default sorting order of results from notmuch.el are in
oldest-to-newest. This prefers the opposite.

After running `systemctl --user enable lieer-google.timer`, systemctl created a
symlink pointing from timers.target.wants -> ../lieer-google.timer. I'm not sure
if tracking symlinks in a git repository is such a useful idea.
This commit reminds me that I could and should be using Nix to better manage
symlink creation and destruction.

Until I have more opinions about my workflow with notmuch, I will redefine the
KBDs from Gmail that I'm comfortable with. While not many KBDs are defined here,
evil-collection defines dozens, many of which I find reasonable; those that I
disagree with, I've unbound in this commit.
Composing emails in notmuch feels similar to writing a commit message with
magit. I want to be able to type :x or :wq, but these commands don't DWIM. For
magit, I'd like that behavior to be the same as `C-c C-c`; not surprisingly, for
notmuch, I'd like the same.
I've bound :x to do this for notmuch. I'd like to define a macro that can easily
define buffer-local evil-ex commands for particular modes. This should lower the
cost of defining evil-ex commands and hopefully convince me to support some of
this desired behavior.

Mimmicking the "action", "review", and "waiting" labels that I had in Gmail
using the equivalent labels as tags in notmuch.
|
|
Supporting a predicate to check that all elements in a list are distinct after
applying a transformation function to them.

I'm borrowing from @tazjin's dotfiles, which are stored in Git on Borg. When you
call `nix-build ~/briefcase/mail`, result will output a systemd units, which you
should move to ~/.config/systemd/user/.
The path to `gmi`, which is Lieer's executable, exists in /nix/store, and you
can read it from the systemd unit file (i.e. lieer-google.service). Lieer
synchronizes notmuch with Gmail and Gmail with notmuch.
Here's a general sequence of commands that I ran to set everything up. Special
thank you to @tazjin for helping me with all of this. These steps are not
certified as a tutorial; I'm recalling them from memory. When I set this up
things didn't work as expected immediately and I had to troubleshoot.
```shell
> mkdir -p ~/mail/account.google
> cd ~/mail/account.google
> nix-env -iA nixpkgs.notmuch
> notmuch setup
> nix-build ~/briefcase/mail
> cp ./result/lieer-google.{service,timer} ~/.config/systemd/user
> rm ./result
> systemctl --user cat lieer-google
...copy the /nix/store path to gmi...
> notmuch new
> /nix/store/gmi init
...follow the OAuth login flow...
>
```
Unknowns?
- Do I need to call `systemctl --user start lieer-google` at startup? Or should
I move these units to user/default.target.wants?
- Can I send email from notmuch?
- How do I use notmuch to delete email? To respond to emails? To do anything?
Todo:
- Once this configuration stabilizes, I should package everything with Nix.

Write a function to merge meeting times. Added an in-place solution, which the
"Bonus" section suggested attempting to solve.
- Added some simple benchmarks to test the performance differences between the
in-place and not-in-place variants. To my surprise, the in-place solution was
consistently slower than the not-in-place solution.

After working with fish for a few weeks, I've decided that I prefer aliases to
abbreviations.
Why? When I reverse search through my command history, I search for the
what I typed and not what it expanded to. Some of my aliases wrap existing
tools encoding my preference for tool A if tool B isn't available. For example I
alias vim to neovim. When nvim isn't available on $PATH, typing vim will
expand to nvim, which will in turn fail.
|
|
I don't see much value in this tool for my workflow.
|
|
I previously had an alias defined as `simple_vim`, which would start an instance
of Vim with a bare bones config. I had a to-do to Nixify it. That is
now (mostly) to-done.
When I try and install it with `nix-env -f ~/briefcase -iA tools.simple_vim`,
Nix fails and says that pkgs.stdenv is undefined. I will need to fix this one
day, but it is neither important nor urgent...
|
|
Defining an alias in my config.fish makes me realize that I should prune many of
my abbreviations and change the ones that remain into aliases.
|
|
I had a spare fifteen minutes and decided that I should tidy up my
monorepo. The work of tidying up is not finished; this is a small step in the
right direction.
TL;DR
- Created a tools directory
- Created a scratch directory (see README.md for more information)
- Added README.md to third_party
- Renamed delete_dotfile_symlinks -> symlinkManager
- Packaged symlinkManager as an executable symlink-mgr using buildGo

Wrote a function in TypeScript to reverse an array of characters mutatively.

I'd like the top-level files in deepmind/part_two to correspond 1:1 with the
TODOs in my org file tracking the work.
|
|
I was a bit weaker than I expected to be in my most recent interview using
TypeScript. To improve, I think I'd like to attempt solving some of the
InterviewCake.com questions using TypeScript.
If you've read the previous commits, the inspiration for `run` arose because I
need to call `npx ts-code <file>`, which is easy enough to remember, but I'd
still rather just call `run <file>`.
|
|
I'd like to be able to just call `run file.py` and have a program DWIM. I'm
working on run as a step in this direction. Define a simple configuration that
maps file extensions to template strings where "$file" is replaced with the
argv[1].
It basically works but there are outstanding TODOs. See the README and source
code for more information.
|
|
Supporting a function that resolves a file name checking for the nearest
occurrence of the file from the CWD until it traverses beyond the user's home
directory, after which point it checks in backupPaths.
|
|
Support predicate for checking if a file exists on disk.
|
|
Support function for returning the home directory of the current user.
|
|
This way I can track what I've done and what I need to do.

Today when I opened my laptop, I wasn't sure if it was powered off or on because
the display was blank. Thankfully the volume was muted and the LED indicator was
on, which informed me that the laptop was powered on. This saved me from
unnecessarily rebooting.
What happened was that last night I was working from home and using my external
monitor. Usually I enable my external display and disable my laptop display. But
when I left for work this morning, I unplugged the HDMI cable from my laptop
without disabling the external display or enabling the laptop display.
I noticed a XF86 button on my laptop entitled XF86Display. I figured that this
could be a nice place to bind a key to toggle my laptop display on or off. At
the last minute, I had the idea to just cycle through all possible display
configurations that I use; there are only three anyways. When dealing with more
than two states, I realized I should use a cycle to model the configuration
states. Now I'm thinking that I should be using cycles to model toggles as well
- instead of just using a top-level variable that I `setq` over. I haven't
refactored existing toggles to be cycles, but I am excited about this new
keybinding.
This commit additionally:
- Moves keybindings out of display.el and into keybindings.el
- Conditionally sets KBDs if using work laptop

When I ran `pass show some/password`, gpg, which uses pinentry would start its
ncurses password prompt. For many this wouldn't be a problem but my current
vterm version cannot send the <return> key to ncurses, so once that prompt
appears, I cannot get rid of it without C-c and killing the shell. For a day or
more I just opened suffered through this.
Today I dug more into the issue and when I ran `pinentry --version` it warned
that it couldn't connect to DBUS. After searching for more information on this,
people with similar issues recommended starting their window managers with
`dbus-launch`. I previously started Emacs with `dbus-launch`, but only because
some i3 documentation told me to do so and I just copied them. Then I switched
to EXWM and copied that pattern over. A friend of mine uses EXWM and starts his
without calling `dbus-launch` but `exec emacs`. I mirrored this thinking that I
no longer needed `dbus-launch`. What I didn't know, however, was that this
friend was using a Nix-built Emacs (like me) except that his wrapped a native
Emacs installation while mine doesn't. His natively wrapped Emacs installation
has the proper variables set to interact with dbus and other important Linuxy
things that I don't fully understand. Since I'm using a Nix-built Emacs, some of
my variables are unset or set to different values than programs expect. This is
why when I try and start `gnome-terminal` or `terminator`, they refuse to start
and warn about many unset or incorrectly variables and not being able to bind to
sockets, etc.
This change reverts back to using `dbus-launch` until I have a better
understanding of Linux, Nix, etc.

After reading these docs
https://api.youneedabudget.com/v1#/Transactions/createTransaction I successfully
made a request to post a transaction to my YNAB account. Hastily created a
client.go that doesn't contain much at the moment.

Grouping entries by country and sorting according to Done -> Todo.
I should consider sorting the country groups alphabetically by the country name
and then each entry alphabetically by its city name.
Right now, however, this isn't a priority.

In 2013, I lived in Grenoble with a host family. During that time, I visited
Lyons, as well as a few other locations that aren't tracked by this document at

I spent two weeks on the Spanish islands of Ibiza and Formentera over the
summer.
I went to Hamburg twice to visit Mimi's family - once in the summer; once for
Christmas.
In the Fall, I went to Bordeaux with Mimi where we stayed at a charming Airbnb.
I spent New Years Eve in Amsterdam with Matty, Ryan, and Conor.
I may be missing a few other places that I visited in 2019; it was an active
year.

Without these KBDs, C-k kills buffers. As an evil-mode user, I expect C-k to
move upwards. As such, adding the `ivy-switch-buffer-map` to my existing ivy
KBDs that handle a similar use-case.
Note: I'm unsure why the KBDs in evil-collection didn't cover this.
