-title: "Cell Phone Experiment"
-date: 2020-04-02T02:02:07Z
-draft: false

-
-### TL;DR
-
-I will not use my cell phone during March to learn more about how much I depend
-on it.
-
-### Explore/Exploit
-
-Ever since I read Charles Duhigg's book, [The Power of Habit](poh), I try to
-habituate as many aspects of my life as I can.
-
-Making my bed every morning is an example of a habit -- so too is flossing at
-night before bed.
-
-The *exploit* axis of the [explore/exploit tradeoff](exp-exp) endows habits with
-their power. Brian Christian and Tom Griffiths explain this concept more clearly
-than I can in Chapter 2 of their exceptional book, [Algorithms to Live
-By](algos).
-
-Habits are powerful, but if I overly exploit an activity, I may settle on a
-local optimum in lieu of settling on a global optimum; these are the opportunity
-costs of exploiting (i.e. habits) versus exploring (i.e. spontaneity).
-
-But what if it was possible to habituate exploration?
-
-### Monthly challenges
-
-Every month since October 2018, I challenge myself to try something new. In the
-past, monthly challenges have been things like:
-- sign up and take Brazilian Jiu Jitsu classes
-- buy a guitar and learn [Freight Train](https://www.youtube.com/watch?v=IUK8emiWabU)
-- study Italian
-- learn a handstand
-
-Typically for an activity to qualify as a challenge, I must spend *at least
-fifteen minutes* working on it *at least five days* each week.
-
-This month (i.e. March) I'm challenging myself to avoid using my cell phone.
-
-My parents gave me a cell phone when when I was a freshman in High School; I was
-14 years old. I am now 28, so I have been using a cell phone semi-daily for over
-a decade.
-
-While I enjoy the convenience that my cell phone provides me, I am curious to
-suspend my usage to more clearly understand how much I depend on it...
-
-### April
-
-Now it is early April, and I completed March's challenge. So how was it?
-
-Below I outline the parts of using a cell phone that I missed and the parts that
-I surprisingly did not miss. I will also mention the two times that I used my
-cell phone and why.
-
-The first three things that I missed all relate to time.
-
-#### Timekeeping
-
-On the first day I realized that unless I was near a computer, I did not know
-what time it was.
-
-I exclusively use my cell phone as my watch; I do not wear a watch. To adapt, I
-started looking for clocks around my office and while I was taking public
-transportation. Thankfully London posts the current time on the digital train
-schedules. This oriented me while I was traveling, which was also when I needed
-to know the time the most.
-
-Most of the month, however, I never precisely knew what time it was.
-
-#### Alarm clocks
-
-While I anticipated living without an alarm clock prior to the experiment, I
-decided against buying a substitute. Prior to this month, I theorized that
-morning alarms probably disrupt the quality of my sleep. If I'm tired, shouldn't
-I keep sleeping?
-
-As the month progressed and my 24 hour day morphed into a 25 hour day, I learned
-that I would prefer waking up at a set time every day and synchronize my
-schedule with the rest of my timezone.
-
-I am still unsure if alarm clocks are helpful in the long-term. I would have
-slept with the curtains drawn to allow the morning sun to wake me
-up. Unfortunately, I live on the ground floor nearby a brightly shining street
-lamp that spills into my bedroom.
-
-If I lived somewhere more remote (perhaps even a suburb would do) I would like
-to repeat an experiment where I live for a month without an alarm clock.
-
-For now, I must return to the Temple of Chronology and supplicate until Father
-Time restores my sanity.
-
-#### Timers
-
-Using timers motivates me to do a bunch of short tasks like cleaning my flat for
-fifteen minutes, stretching, or reading before bed. Thankfully, I already owned
-a physical timer that I keep in my kitchen. This replaced the timer on my phone
-without disrupting my routine.
-
-#### Maps
-
-Speaking of being disoriented, what about living without maps software?  On the
-few occasions where I traveled somewhere that was unfamiliar to me, I had to
-memorize the directions from my computer before I departed.
-
-At least I didn't need to visit gas stations or museums to buy trifold tourist
-maps...
-
-I once left my office mistakenly assuming that I would download the directions
-to my destination while commuting. As I awaited the office elevator, I realized
-that I had no clue where I was heading.
-
-Thankfully I wasn't far from the safety, comfort, and familiarity of my desktop
-computer -- with its fatty WiFi connection. In no time I was studying Google
-Maps in my web browser and memorizing the directions.
-
-Overall this was hardly an inconvenience, and I think I even enjoyed
-stress-testing my memory: a job that I so often outsource to hardware.
-
-#### Rendezvouses
-
-A couple of times I met friends in various parts of the city. Organizing these
-particular rendezvouses was a novel (read: anachronistic) experience. For all
-you young whippersnappers reading, take out your stone tablets and chisels. I'm
-going to explain how this works:
-
-First I would tell my friends where and when to meet me. I emphasized that I
-would be quite helpless to any changes they might make to the plans once I began
-commuting, which made the commitments unusually more binding.
-
-On one occasion my friend -- who is characteristically prompt, and even chides
-me for when I'm late -- was twenty minutes late for our engagement. My friend is
-German, so I figured I should do my civic duty of alerting the German embassy
-that my friend had broken German code, is obscenely late, and should therefore
-hand-in his passport and renounce his citizenship. After awhile my conscience
-advised me to reconsider.
-
-It was fortunate for both of us that I did not fully understand how late he was.
-Remember: I didn't know what time it was.
-
-I decided this would be a useful opportunity to test my patience, so I loitered
-for twenty minutes outside of our meeting point. He couldn't text me to tell me
-that he was late. I couldn't listen to music, call family or friends, or partake
-in any of the other rituals that modern-day loiterers observe to pass the
-time. In the end he showed up, and it was scarcely a big deal.
-
-This experience made me wonder what the policy for abandoning plans is when
-someone is running late. Before smart phones, how long did people wait? Maybe
-the proper etiquette is to wait long enough for you to absolve yourself of the
-guilt of flaking in the unlikely event that your friend arrives shortly after
-you leave.
-
-So... thirty minutes? I'll call my grandma tomorrow and ask her.
-
-#### Boredom
-
-My phone couldn't entertain me while I queued at the grocery store. Same too
-when I commuted.
-
-I also found myself listening to less music than I usually do. I decided to read
-to occupy the void when I could; this helped me progress towards completing this
-year's [GoodReads challenge][gr-annual].
-
-### Cheating
-
-I used my phone twice during March.
-
-1. Once to use my bank's mobile app to internationally transfer money from my
-   U.K. account to my U.S. account. I could have used [TransferWise's][tw]
-   website, but I didn't.
-2. Another time I used my phone to take pictures of an item that I wanted to
-   sell on [CraigsList][cl]. I could have and perhaps should have used my laptop's
-   webcam, but at the time, I didn't want to. I am accustomed to using my phone
-   to take pictures, and I wanted to sell something.
-
-In both of these cases, prior habits eroded my resolve to stay the course. These
-are useful reminders that habits don't distinguish between helpful and hurtful;
-they just exist.
-
-In total I would estimate that I spent somewhere around fifteen minutes using
-my phone in March. While not perfect:
-
-> Better a diamond with a flaw than a pebble without (Confucius)
-
-### Substitution = Dilution
-
-While the explicit goal of this challenge was to avoid using my cell phone for a
-month, the implicit goal was to disengage from many of the
-[nonessential][essentialism] activities that compete for my attention.
-
-There were some activities that I didn't miss while living without a cell
-phone. This wasn't because I don't value these activities, but rather because I
-can adequately replace them with alternatives.
-
-For texting and making phone calls, I used [Telegram][wtf-telegram]. Telegram
-helped me sustain a healthy relationship with my girlfriend while still honoring
-the constraints of the challenge.
-
-While I appreciated the convenience Telegram provided, I felt that I remained
-about as [available][wtf-availability] during March as I was in February. If I
-ever experiment with drastically reducing my availability, I will be more
-explicit about my objectives.
-
-### Distraction displacement (whack-a-mole)
-
-Because cell phones and other electronics have conditioned my behavior, I
-habitually avoid boredom and seek entertainment. On its face this may not sound
-like a harmful practice. My generation drills the aphorism "you only live once",
-suggesting that we may want to embrace a Hedonistic lifestyle.
-
-Hedonism may or may not be a wise way to play the game of Life. All I know is
-that living a life in which I am often stimulated but proportionately distracted
-appeals increasingly less to me as time progresses.
-
-During March I noticed that once I freed my attention from sending/receiving
-texts, my brain quickly reassigned my attention to maintaining a vigil over the
-other social media outposts that I maintain.
-
-I should also admit that I habitually checked Telegram now that it served as my
-new cell phone. Didn't see that coming...
-
-In another case, once I discovered that I could use Instagram in a web browser
-instead of on my phone, I filled my newfound time and attention on
-[Instagram.com][ig] (don't click!): displacing the time that I spent on an app
-on my phone to time that I spent on a website in a web browser.
-
-Holy whack-a-mole!
-
-Halfway through the month, I wrote a [program to block websites][url-blocker] on
-my computer. Surprisingly this worked and forced me to more deliberately fill
-this hard-fought, foreign time with other activities.
-
-### Easy come, easy go?
-
-As the saying for making friends goes, "easy come, easy go", implying that
-friendships that you easily form can just as easily be destroyed.
-
-Habits invert this creation/destruction relationship. In my experience "easy
-come" implies "difficult to go".
-
-For example, I could easily form the habit of eating chocolate around 15:00 at
-work; curbing this habit would require more effort. When I compare this to the
-difficulty I experienced habituating a meditation practice, and how easily I
-can dislodge my meditation practice, it seems to me that the laws of habits
-dictate "easy come, difficult go; difficult come, easy go".
-
-I suspect that while my cravings for using a cell phone have temporarily ceased,
-they will return shortly after I start using my cell phone. And as if nothing
-happened, I return to where I was at the end of February just before I decided
-to curb my cell phone usage.
-
-Because of this, I'm planning on keeping my cell phone in my closet where I
-stored it during the month of March. As noted, enough substitutes exist for me
-to live a mostly normal life: one where I am not unnecessarily straining the
-relationships of my friends and my family. After all these are the people who
-matter most to me and those who drive me to explore new ways to improve.
-
-I recognize that the "self" in self-experimentation is a misnomer. Can you truly
-conduct an [N of 1 trial][nof1]? My decisions impact the people in my life, and
-I want to thank everyone who tolerates my eccentric and oftentimes annoying
-experimentation.
-
-Thank you for reading.

-## TL;DR
-
-1. I use `NixOS/nixpkgs-channels` instead of `NixOS/nixpkgs` and avoid
-   `nix-channel`.
-
-## More information
-
-- By default the Nix package manager uses cache.nixos.org as a binary cache.
-- Visit status.nixos.org
-- `git clone git@github.com:NixOS/nixpkgs-channels` instead of
-  `NixOS/nixpkgs`. The former mirrors the latter and uses Git branches to track
-  the published channels.
-
-## What is a Nix channel
-
-If you run...
-
-```shell
-$ git clone git@github.com:NixOS/nixpkgs ~/nixpkgs
-$ export NIX_PATH="nixpkgs=$(realpath ~/nixpkgs)"
-```
-
-One benefit to cloning nixpkgs is that you can browse the source code on your
-machine using tools like `git` and `emacs`. You can also experimentally patch
-and test Nix code this way.
-
-If any of the above appeals to you, clone `nixpkgs-channels` instead.
-
-The Nix maintainers build and test the commits from `nixpkgs` using Hydra. Tests
-include reproducibility tests, etc.
-
-Various channels have different verification phases.
-
-The cache at cache.nixos.org is populate the cache at cache.nixos.org.
-
-You want to increase the likelihood that you are hitting this cache. For
-example, `google-chrome` takes hours to build.

-
-I am dedicating this page to defining and disambiguating some terminology. I
-think it is important to use these terms precisely, so it may be worthwhile to
-memorize these definitions and ensure that you are clarifying the discourse
-rather than muddying it.
-
-## Terms
-
-- repeatable build:
-- reproducible build:
-- deterministic build:
-- pure function:
-- impure function:
-- idempotent function:
-
-TODO(wpcarro): Consistently and deliberately use reproducible and
-deterministic.
-
-## Repeatable vs. Reproducible
-
-Is NixOS reproducible? Visit [@grhmc][who-grhmc]'s website,
-[r13y.com](https://r13y.com), to find out.
-
-At the time of this writing, 1519 of 1568 (i.e. 96.9%) of the paths in the
-`nixos.iso_minimal.x86_64-linux` installation image are reproducible.
-
-## What hinders reproducibility?
-
-Timestamps.
-
-If package A encodes a timestamp into its build artifact, then we can
-demonstrate that package A is *not reproducible* simply by building it at two
-different times and doing a byte-for-byte comparison of the build artifacts.
-
-## Does Nix protect developers against non-determinism
-
-Yes. But not entirely. How?
-
-## Deterministic Nix derivation
-
-```nix
-{ pkgs ? import <nixpkgs> {}, ... }:
-
-with pkgs;
-
-stdenv.mkDerivation {
-  name = "reproducible";
-  phases = [ "buildPhase" ];
-  buildPhase = "echo reproducible >$out";
-}
-```
-
-## Non-deterministic Nix derivation
-
-We can introduce some non-determinism into our build using the `date` function.
-
-```nix
-# file: /tmp/test.nix
-{ pkgs ? import <nixpkgs> {}, ... }:
-
-with pkgs;
-
-stdenv.mkDerivation {
-  name = "non-reproducible";
-  phases = [ "buildPhase" ];
-  buildPhase = "date >$out";
-}
-```
-
-Then run...
-
-```shell
-$ nix-build /tmp/test.nix
-$ nix-build /tmp/test.nix --check --keep-failed
-```
-
-## How do you test reproducibility?
-
-We can use `cmp` to compare files byte-for-byte. The following comparison should
-fail:
-
-```shell
-$ echo foo >/tmp/a
-$ echo bar >/tmp/b
-$ cmp --silent /tmp/{a,b}
-$ echo $?
-```
-
-And the following comparison should succeed:
-
-```shell
-$ echo hello >/tmp/a
-$ echo hello >/tmp/b
-$ cmp --silent /tmp/{a,b}
-$ echo $?
-```
-
-## Reproducible vs. deterministic
-
-Reproducible builds *are* deterministic builds and deterministic build
-
-## Deterministic, Reproducible, Pure, Idempotent, oh my
-
-- A pure function has no side-effects.
-
-- An idempotent function can be executed more than once with the same arguments
-  without altering the side-effects.
-
-- A deterministic function ensures that

-## Let's Learn Nix: Dotfiles
-
-### Dependencies
-
-Speaking of dependencies, here's what you should know before reading this tutorial.
-
-- Basic Nix syntax: Nix 1p
-
-What version of Nix are we using? What version of `<nixpkgs>` are we using? What
-operating system are we using? So many variables...
-
-Cartesian product of all possibilities...
-
-TODO(wpcarro): Create a graphic of the options.
-
-### The problems of dotfiles
-
-How do you manage your dependencies?
-
-You can use `stow` to install the dotfiles.
-
-### home-manager
-
-What we are going to write is most likely less preferable to the following
-alternatives:
-- using Nix home-manager
-- committing your `.gitconfig` into your
-
-In the next tutorial, we will use [home-manager][wtf-home-mgr] to replace the
-functionality that we wrote.
-
-So why bother completing this?
-
-### Let's begin
-
-Welcome to the first tutorial in the [Let's Learn Nix][wtf-lln] series. Today we
-are going to create a Nix derivation for one of your dotfiles.
-
-"Dotfiles" refers to a user's collection of configuration files. Typically these
-files look like:
-- `.vimrc`
-- `.xsessionrc`
-- `.bashrc`
-
-The leading "dot" at the beginning gives dotfiles their name.
-
-You probably have amassed a collection of dotfiles whether or not you are
-aware. For example, if you use [git][wtf-git], the file `~/.gitconfig` should
-exist on your machine. You can verify this with:
-
-```shell
-$ stat ~/.gitconfig
-```
-
-When I was first learning `git`, I learned to configure it using commands I
-found in books and tutorials that often looked like:
-
-```shell
-$ git config user.email
-```
-
-The `~/.gitconfig` file on your machine may look something like this:
-
-```.gitconfig
-[user]
-	name = John Cleese
-	email = john@flying-circus.com
-	username = jcleese
-[core]
-	editor = emacs
-[web]
-	browser = google-chrome
-[rerere]
-	enabled = 1
-	autoupdate = 1
-[push]
-	default = matching
-[color]
-	ui = auto
-[alias]
-	a = add --all
-	ai = add -i
-	b = branch
-	cl = clone
-	cp = cherry-pick
-	d = diff
-	fo = fetch origin
-	lg = log --oneline --graph --decorate
-	ps = push
-	pb = pull --rebase
-	s = status
-```
-
-As I ran increasingly more `git config` commands to configure my `git`
-preferences, the size of my `.gitconfig` increased, and the less likely I was to
-remember which options I set to which values.
-
-Thankfully a coworker at the time, Ryan ([@rschmukler][who-ryan]), told me that
-he version-controlled his `.gitconfig` file along with his other configuration
-files (e.g. `.vimrc`) in a repository he called "dotfiles".
-
-Version-controlling your dotfiles improves upon a workflow where you have a
-variety of configuration files scattered around your machine.
-
-If you look at the above `.gitconfig`, can you spot the dependencies?
-
-We explicitly depend `emacs` and `google-chrome`. We also *implicitly* depend on
-`git`: there is not much value of having a `.gitconfig` file if you also do not
-have `git` installed on your machine.
-
-Dependencies:
-- `emacs`
-- `google-chrome`
-
-Let's use Nix to generate this `.gitconfig` file. Here is what I would like our
-API to be:
-
-Let's create a file `gitconfig.nix` and build our function section-by-section:
-

-We want to write a function that accepts an attribute set and returns a
-string. While Nix is a dynamically typed programming language, thinking in types
-helps me clarify what I'm trying to write.
-
-```haskell
-encodeAttrSet :: AttrSet -> String
-```
-
-I prefer using a Haskell-inspired syntax for describing type signatures. Even if
-you haven't written Haskell before, you may find the syntax intuitive.
-
-Here is a non comprehensive, but demonstrative list of example type signatures:
-- `[String]`: A list of strings (i.e. `[ "cogito" "ergo" "sum" ]`)
-- `AttrSet`: A nix attribute set (i.e. `{ name = "John Cleese"; age = 80; }`).
-- `add :: Integer -> Integer -> Integer`: A function named `add` that accepts
-  two integers and returns an integer.
-
-Specifically, we want to make sure that when we call:
-
-```nix
-encodeAttrSet {
-  a = "add --all";
-  b = "branch";
-}
-```
-
-...it returns a string that looks like this:
-
-```.gitconfig
-a = "add --all"
-b = "branch"
-```
-
-
-TODO(wpcarro): @tazjin's nix-1p mentions this. Link to it.
-Nix has useful functions scattered all over the place:
-- `lib.nix`
-- `list.nix`
-- `lib.attrSet`
-
-But I cannot recall exactly which functions we will need to write
-`encodeAttrSet`. In these cases, I do the following:
-1. Run `nix repl`.
-2. Browse the Nix source code.
-
-Google "nix attribute sets" and find the Github link to `attrsets.nix`.
-
-You should consider repeating this search but instead of searching for
-"attribute sets" search for "lists" and "strings". That is how I found the
-functions needed to write `encodeAttrSet`. Let's return to our `nix repl`.
-
-Load the nixpkgs set:
-
-```nix
-nix-repl> :l <nixpkgs>
-Added 11484 variables.
-```
-
-Define a test input called `attrs`:
-
-```nix
-nix-repl> attrs = { fname = "John"; lname = "Cleese"; }
-```
-
-Map the attribute set into `[String]` using `lib.mapAttrsToList`:
-
-```nix
-nix-repl> lib.mapAttrsToList (k: v: "${k} = ${toString v}") attrs
-[ "fname = John" "lname = Cleese" ]
-```
-
-Now join the `[String]` together using `lib.concatStringsSep`:
-
-```nix
-nix-repl> lib.concatStringsSep "\n" (lib.mapAttrsToList (k: v: "${k} = ${v}") attrs)
-"fname = John\nlname = Cleese"
-```
-
-Now let's use this to define our function `encodeAttrSet`:
-
-```nix
-# file: gitconfig.nix
-encodeAttrSet = xs: lib.concatStringsSep "\n" (lib.mapAttrsToList (k: v: "${k} = ${v}") xs);
-```

-- Where does `emacs` exist? What about `google-chrome`? [nixpkgs search][wtf-nixpkgs-search]
-- Verify that I have it? [nix REPL][using-nix-repl]

-## Background
-
-[Nix][wtf-nix] may be the most useful tool that I use. I consider it as valuable
-as [Git][wtf-git] or [Emacs][wtf-emacs]. My friend, David ([@dmjio][who-dmjio]),
-first introduced me to Nix when we worked together at a Haskell startup in
-NYC. Before this, I had been managing my system configuration using software
-that I wrote -- first in Bash, then in Python, then in Golang.
-
-It took me awhile to understand Nix. I left the NYC startup, joined Google, and
-relocated to London. Here I met another Nix-enlightened monk, Vincent
-([@tazjin][who-tazjin]), who patiently taught me enough Nix to become
-self-reliant and productive.
-
-Many resources exist to learn Nix; the Nix community on IRC continues to help me
-and others effectively use Nix. I'm creating this series to write the tutorials
-that I would have found useful when I started learning Nix. If you are just
-beginning your Nix journey, I hope these tutorials help you.
-
-## Goals
-
-I aim to make each tutorial in the "Let's Learn Nix" series:
-- Actionable: Readers will be writing code.
-- Digestible: Readers should be able to finish each tutorial in fifteen minutes.
-- Reproducible: Readers should expect the output of their code to match what
-  these tutorials claim they should see.
-
-## About the author
-
-My name is William ([@wpcarro][who-wpcarro]). My three favorite tools are Git,
-Emacs, and Nix. I am an American expat currently working at Google in
-London. While during the day I primarily write Java, Python, and TypeScript, I
-prefer functional programming. I use Nix to deploy software and manage the
-multiple machines across which I work.
-
-## Let's Begin
-
-Before we get started, Nix is a programming language. To familiarize yourself
-with the syntax, semantics, and idioms, consider reading this brief [Nix One
-Pager][nix-1p]. I recommend keeping it around as a reference.
-
-When I was first learning Nix, I wanted to use it to manage my dotfiles. Our
-first tutorial will help you get started: [Let's Learn Nix:
-Dotfiles][lln-dotfiles]
