transform probabilities based on a set of heuristics. The family should
include both convex and concave functions. The family should also
satisfy the following constraints:</p>

<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>f(0; a) = 0
f(1; a) = 1
f(x; 1) ≅ x
f(0; inf) ≅ step function at 0
f(1; 0) ≅ step function at 1
</code></pre></div></div>

<p>Practically speaking, <code class="language-plaintext highlighter-rouge">f(x) = x^a</code> functions well for these constraints,
but I wanted something “symmetric” for a very specific meaning of the
word:</p>

<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>f(1-f(x)) = 1 - x
</code></pre></div></div>

<p>In words, the graph should be symmetric around the line <code class="language-plaintext highlighter-rouge">x + y = 1</code>.</p>

<p>Despite not having any practical need, I spent a couple hours on it,
chatted with a buddy who enjoys such puzzles, and even ended up emailing
an old math professor of mine looking for an answer. My buddy, the
brilliant Chris Poirel, ended up coming through: use a parameterized,
transformed quadrant of the circle:</p>

<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>f(x; a) = ((1-(1-x)^a)^(1/a)
</code></pre></div></div>

<p>This is the “upper left” quadrant, moved over, and parameterized by how
much curve it has. Large <code class="language-plaintext highlighter-rouge">a</code> looks like a box, while small <code class="language-plaintext highlighter-rouge">a</code> (0 &lt; <code class="language-plaintext highlighter-rouge">a</code> &lt; 1)
starts to look like a star. And of course</p>

Periodically this data is swept up and processed in a batch, and the
processing archives off the chunk of raw data it processes, gzipping it
along the way. As a result, after a period of time, there are a number
of gzipped, textual data files sitting around. I was interested in
batching these up into a single, larger file that I could upload to S3
or the like for later reprocessing. I sat down to write a bash script to
take care of this process, but before I got through my first for loop, I
wondered if there could be a better way.</p>

<p>I discovered that the gzip format can contain
multiple compressed chunks, which are concatenated when decompressed!
From <a href="https://en.wikipedia.org/wiki/Gzip">Wikipedia</a>:</p>

<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>[Gzip's] file format also allows for multiple such streams to be
concatenated (zipped files are simply decompressed concatenated as if
they were originally one file)
</code></pre></div></div>

<p>That means that the <em>gzipped files themselves</em> can be concatenated, and
the effect is as if you had concatenated the original files and then
gzipped. Check it out:</p>

<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>vagrant@vagrant-ubuntu-trusty-64:/tmp$ cat test1 test2 
My
name 
is
Joseph
Turner
and
I
love
pancakes
vagrant@vagrant-ubuntu-trusty-64:/tmp$ gzip test1
vagrant@vagrant-ubuntu-trusty-64:/tmp$ gzip test2
vagrant@vagrant-ubuntu-trusty-64:/tmp$ cat test1.gz test2.gz &gt; test3.gz
vagrant@vagrant-ubuntu-trusty-64:/tmp$ gunzip test3.gz 
vagrant@vagrant-ubuntu-trusty-64:/tmp$ cat test3 
My
name 
is
Joseph
Turner
and
I

</code></pre></div></div>

<p>One downside is that the original filenames are lost, so decompressing
with the <code class="language-plaintext highlighter-rouge">-N</code> flag results in a file with the first chunk’s filename:</p>

<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>vagrant@vagrant-ubuntu-trusty-64:/tmp$ cat test1.gz test2.gz &gt; test3.gz
vagrant@vagrant-ubuntu-trusty-64:/tmp$ gunzip -N test3.gz
vagrant@vagrant-ubuntu-trusty-64:/tmp$ ls
test1  test1.gz  test2.gz
</code></pre></div></div>

<p>For my purpose, which would prefer the concatenated file, this was a small price to pay for avoiding the roundtrip
compression. If you need to preserve original filenames, you can simply
use the <code class="language-plaintext highlighter-rouge">tar</code> utility to combine the compressed files into a single file.</p>]]></content><author><name></name></author><summary type="html"><![CDATA[I’ve got a system that is running constantly and producing data.

file. I originally started with a simple solution:</p>

<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>cat /my/path/*.data
</code></pre></div></div>

<p>This worked fine, until there were more files than <code class="language-plaintext highlighter-rouge">cat</code> could handle (on
my system, this was somewhere around 150k files):</p>

<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>/tmp/tests$ for i in `seq 150000`; do echo $i &gt; $i; done           
/tmp/tests$ cat *                                                  
-bash: /bin/cat: Argument list too long
</code></pre></div></div>

<p>Next, I tried a simple loop:</p>

<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code># Elided: code to check for big_file.data and create/clear it if it
#   is missing
for file in `ls /my/path | egrep '.data$'`; do
    cat /my/path/$file &gt;&gt; big_file.data;
done                
</code></pre></div></div>

<p>This works, but is slow, much slower than the first solution. No need to
despair: a bit of research uncovered a neat feature for the <code class="language-plaintext highlighter-rouge">find</code>
command:</p>

<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>-exec command {} +
       This variant of the -exec action runs the specified command on the selected  files,
       but  the command line is built by appending each selected file name at the end; the
       total number of invocations of the command will be much less  than  the  number  of
       matched  files.   The  command line is built in much the same way that xargs builds
       its command lines.  Only one instance of `{}' is allowed within the  command.   The
       command is executed in the starting directory.
</code></pre></div></div>

<p>In other words, it’ll batch the results for you and pass them to the
command. In our example, we wind up with this:</p>

<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>find /my/path -maxdepth 1 -type f -name '*.data' -exec cat {} + &gt; big_file.data
</code></pre></div></div>

<p>This will batch together files into reasonable chunks and call the
command (cat in this case) with the chunks!</p>]]></content><author><name></name></author><summary type="html"><![CDATA[Today I found myself needing to concatenate many files to make one long file.

investing. I read some books (<a href="http://amzn.to/2Ep24ig">this one</a> being
my favorite), talked to some  smarter and more experienced people, and
synthesized that information with my own experience and logic. And then
got after it. I bought myself a fixer-upper to live in, rented out my
condo, and bought a foreclosure (one of the dreaded <a href="https://www.biggerpockets.com/renewsblog/2015/08/22/truth-30k-investment-properties/">$30k
properties</a>)
to fix up and rent. Ultimately, my girlfriend got into grad school in
North Carolina and I ended up liquidating all three, so it wasn’t the
slow-build, buy-and-hold investing I had set out to do. I ended up with
more tax liability than I would have planned for, but in the end I made
a tidy bit of money on each property.</p>

<p>I learned a ton along the way, but I think my (modest) success was more
a function of distilling the information I absorbed into a set of what
<a href="http://amzn.to/2Ha0L4d">Ray Dalio calls principles</a>: broadly applicable
concepts that generalize well to a number of situations. By
understanding and adhering to these principals, I was able to make money
from my properties, even without the long timeline I had originally
envisioned.</p>

<p>What follows are what I jokingly referred to as The Rules of Real
Estate. When my girlfriend and I began looking at houses to start our
journey, she would sometimes become enamored with a property or overly
excited. I would slap on a half-smile and refer her to one of the
“rules” she was violating. This banter contributed to my success, by
helping reinforce these rules in my mind. Because they came about this
way, they look a lot like a set of real estate-related <a href="https://en.wikipedia.org/wiki/Cognitive_bias">cognitive
biases</a>: stumbling blocks
we set up for ourselves in the evaluation of real estate deals.
Following these principles helps you avoid common mental pitfalls so
that you have a better chance of making money on any deal you do.</p>

<h2 id="the-rules-of-real-estate">The Rules of Real Estate</h2>
<h3 id="rule-1-dont-make-decisions-based-on-emotion">Rule 1: Don’t make decisions based on emotion</h3>
<p>This rule is most often violated when looking at purchasing your own
home, and much of the real estate “machine” pushes you toward an
emotional decision. You tour properties with your agent. Maybe your
agent takes you to to a few beaters first, to show off some of the
“other inventory”. You plod through each property, finding fault after
fault, and despair ever finding a home. Then you go to a property that
is well-updated, looks great, and smells like cookies, even if it is 15%
above what you wanted to pay. Your agent mentions that they’ve already
got other offers they’re considering, or that she’s shown this property
a lot and there’s been a ton of interest. You go home and have a
discussion with your partner: there’s not much left on the market right
now, and someone is sure to scoop this one up! Let’s make an offer near
asking price to ensure we get it, ahead of the other offers.</p>

<p>You’ve just made a decision based on emotion, and as a result you’re
less likely to make money on the deal. Don’t feel bad; it’s really hard
not to, and it requires discipline and diligence on your part. As I said
above, many of the steps I just described prey on your human nature. The
long day of touring homes results in <a href="https://en.wikipedia.org/wiki/Decision_fatigue">decision
fatigue</a>. The dumpy
properties you looked at first activate the <a href="https://en.wikipedia.org/wiki/Contrast_effect">contrast
effect</a>, making the last
property look like a mansion, and the lack of inventory triggers a
<a href="https://en.wikipedia.org/wiki/Scarcity_heuristic">scarcity response</a>.
The sidenote about other offers triggers yet another scarcity heuristic,
this one about time: you need to get an offer in quick! All of these
factors trigger emotional responses, and put your mind in a state where
it is challenging to make the best decisions.</p>

<p>Objectively, these emotional triggers are just that and little else.
There are ugly, overpriced, terrible properties in any market. There
will always be more inventory if you take your time to find a deal. And
your offer should always be an objective reflection of your efforts at
valuing the property yourself. So how do we put aside the inbuilt,
emotional responses and engage our logical brains?</p>

<p>It turns out that we can’t, really. The best we can do is to be informed
of our shortcomings, and to insist on structuring our choices in such a
way that we have time for logical reflection. The former can be
accomplished through books like <a href="http://amzn.to/2CzF2zu">this one</a> or
<a href="http://amzn.to/2HqRYuV">this one</a> (my personal favorite), or even blog
posts like the one you’re reading. The latter can be accomplished by
carefully breaking each deal down in the same way, financially and
logically, while giving oneself some reasonable amount of time for
reflection. The time helps avoid the scarcity problems and the
methodical deal evaluation engages the logical parts of our mind,
helping to ensure we don’t make decisions on emotion alone. After
evaluating enough deals like this, it becomes easier and we become more
resistant to the nefarious (intentional or not) traps laid for our
emotional mind.</p>

<h3 id="rule-2-dont-count-your-chickens-before-they-hatch">Rule 2: Don’t count your chickens before they hatch</h3>

<p>Deals fall through all the time, for all sorts of reasons. As humans, we
tend to <a href="https://en.wikipedia.org/wiki/Loss_aversion">inordinately weight a loss relative to an equivalent
gain</a>. This means that the
loss of a deal, particularly a deal in which we’ve invested ourselves
emotionally, loom large. Additionally, for a deal to have even been on
the table in the first place, we’d need to have made an investment, and
we perceive that investment as a <a href="https://en.wikipedia.org/wiki/Sunk_cost">sunk
cost</a>. Together, these factors
mean that we tend to go to lengths, sometimes inappropriate lengths, to
keep a dealt together.</p>

<p>As an example, imagine you have a home inspection on a property. The
inspection uncovers some hidden issues, and you ask for changes. The
owner refuses to address the changes, and refuses to change the sale
price. Often, rather than lose the deal we’ve already invested time (and
maybe some money!) in, we make concessions and accept the property with
the uncovered warts to keep the deal together.</p>

<p>The problem comes when these concessions change the parameters of the
deal we’ve evaluated. If it was a good deal with no changes required,
and it is no longer a good deal with the changes you’d accept, then you
should walk away from the deal. More generally, <strong>don’t count your
chickens before they hatch</strong>: assume the deal will fall through until
the day you get the title. This is true for both purchases and sales.</p>

<p>By distancing yourself from the deal, and assuming the deal will fall
through, it becomes easier to objectively evaluate the situation as it
evolves, ultimately resulting in better decisions.</p>

<h3 id="rule-3-there-will-always-be-another-opportunity">Rule 3: There will always be another opportunity</h3>

<p>This rule is a generalization of the two previous rules. It is a mindset
we should try to coach ourselves into, one that helps shield us from
emotional triggers and loss aversion: no matter what deal we are
currently evaluating, no matter how good it seems or how it evolves, it
is not the only opportunity out there. One of the implications of this
rule is that our mental time scales should reflect the reality of real
estate investing; in other words, many deals really only make sense in a
time scale measured in years, but we tend to evaluate any given deal as
though the inventory and opportunities we’ve looked at recently are all
there is.</p>

<p>The reality is that <strong>there will always be another opportunity</strong>.
Patience, along with an appropriate mindset, means we get the best deals
not just for right now, but for the years to come and for our total
investment potential. In turn, this translates into a better
<em>portfolio</em>, which is a much better goal.</p>

<h3 id="rule-4-you-make-your-money-when-you-buy-not-when-you-sell">Rule 4: You make your money when you buy, not when you sell</h3>

<p>At this point, you’ve prepared yourself. You’ve got a great mindset,
you’ve shielded yourself emotionally, and you’re aware of your loss
aversion. The previous rules have you in a position to objectively
evaluate your deals. To do so, however, you need to do do some homework
and build your knowledge base.</p>

<p>One critical element is researching and internalizing deal evaluation
techniques, including rules of thumb (examples for buy-and-hold rental
properties: the <a href="http://www.123flip.com/education/the-50-rule/">50%
rule</a> and the <a href="https://www.biggerpockets.com/renewsblog/2013/04/14/the-2-percent-rule/">2%
rule</a>).
These rules vary considerably depending on what type of deal you’re
looking for (rentals, flips, etc.). I suggest reading as many books as
you can find and finding a mentor who has done the type of investing
you’re interested in.</p>

<p>Another element is understanding the market you’re working in. This
means putting the legwork in to get a feel for neighborhoods, prices in
your area, the way property values are changing, and more. If you’re
working with a realtor, they can offer some guidance on these elements,
but nothing beats hitting the streets yourself to understand
neighborhoods and how they’re evolving. This is a time consuming
process, but it’s critical to being able to objectively evaluate deals.</p>

<p>If you’re looking at un-renovated properties (and you probably are), and
especially distressed properties, you also need to start learning how to
make rough estimates for the costs of rehab. If you plan on doing some
of the work yourself, start educating yourself on how to do the types of
tasks you want to take on. You should also start getting references and
building relationships with local contractors. A good, reliable
contractor with a fair price can make the difference between a lucrative
deal and a break-even or money losing scenario.</p>

<p>Depending on the type of deal, there are probably also other elements
you need to educate yourself on. The point is, until you build your
knowledge base, you are not ready to objectively evaluate deals. Why is
this so important? Because <strong>you make your money when you buy, not when
you sell</strong>. In other words, the only way to reliably make money is to
buy properties that are objectively good deals. Do your homework, put in
the legwork, and find the deals that will be good regardless of what
happens in the market.</p>

<h3 id="rule-5-always-do-your-diligence">Rule 5: Always do your diligence</h3>

<p>To stand the best chance of making your money when you buy, you need to
fully understand the property you are buying. This means having all
inspections necessary to uncover any hidden issues. The range of
inspections can vary from property to property, but at a minimum this
would include a home inspection, with follow up on any specific issues
uncovered.</p>

<p>As an example, say you had a home inspection and the inspector noted
cracks in the foundation. In some cases, these cracks are not an issue,
but in others they can imply serious stress or even existing damage to a
foundation element. Rather than accepting the inspector report which
simply states that there are cracks, follow up with a licensed engineer
to get an evaluation of the foundation. At first, follow ups like this
can seem expensive, but the are far less expensive than finding out the
house needs foundation work <em>after</em> you buy it.</p>

<p>The output of this diligence should be a list of known issues with
reasonable estimates on the cost of and urgency of repair. This list
then serves as input to the model you build as part of your deal
evaluation. If you are planning to do some work on the property
yourself, you may want to address many of the issues uncovered yourself.
This doesn’t mean you shouldn’t get a reasonable estimate though: these
estimates help you determine the discount on the asking price you should
expect, and they provide leverage for your negotiation. In some states,
you can include an “inspection contingency” - a way to back out of the
contract if the inspection uncovers something you don’t like. These
contingencies are a great way to apply leverage to the seller of the
home. They only work, though, if you’re willing to do your diligence
every time.</p>

<h3 id="rule-6-you-can-change-anything-about-a-property-except-its-location">Rule 6: You can change anything about a property except its location</h3>

<p>Issues uncovered in your inspection, ugly finishes, bad layouts, weird
construction techniques - these are all issues with remedies. A good
contractor can solve almost any problem with a property, though it may
not be cheap. The one thing no contractor can fix, though, is a problem
with the location. As a result, location should be the foremost concern
when evaluating a deal.</p>

<p>If you’ve done your legwork, you should have a good general
understanding of the neighborhoods and areas in which you are looking.
Does the area have a lot of crime, or is it near such an area? Is there
a ton of noise from nearby airports, railroads, or highways? Are busy
streets dangerous for children living there? How are the schools in the
area, and which are the most sought after? Are there sidewalks
connecting the property to grocery stores, restaurants, bars, and other
amenities? Is it a reasonable walk? Are there bike lanes? Is there
public transit nearby? What service providers (internet, cable, etc.)
are available in the area?</p>

<p>You should develop reasonable answers to all these questions as part of
your evaluation. The desirability of a property, whether for resale or
rental, is intimately tied to these factors, and so you should use them
as a way to evaluate a deal. It helps to make a checklist as you do your
evaluation to ensure you have good answers and don’t overlook any
aspect.</p>

<p>Another set of questions, though harder to answer, is about the future
of the location. Is there new construction nearby that will change the
property value? Is the area around the property being revamped? These
sorts of questions are most easily answered by either being or working
with an expert in the area. Realtors can fit this bill. Other area
investors who have been tapped in for some time are also great sources
of information. The future of a location, while not important to the
value of the property today, can mean the difference between a solid
rate of return and a huge home run.</p>

<p>To summarize, as part of your diligence, make sure you have a great
understanding of the location of the property. It is the one thing you
won’t be able to change.</p>

<h3 id="rule-7-break-the-other-rules-only-when-it-makes-sense">Rule 7: Break the other rules only when it makes sense</h3>

<p>Rigid rules are a great way to minimize risk when starting a new
venture. Like a poker player who only plays hands with <a href="https://en.wikipedia.org/wiki/Poker_probability">good
mathematical odds</a>,
rules prevent you from large downside exposure based on the unknown.
However, the best poker players all use bluffing and other
nonmathematical elements to maximize their game. Similarly, to get the
best deals sometimes requires working outside these rules.</p>

<p>When does it make sense to break a rule? The answer is: when you have
enough information to make an informed, confident estimate to the
<a href="https://en.wikipedia.org/wiki/Expected_value">expected value</a>, and the
expected value far outstrips the cost. As with all expected value
calculations, the risk is inversely proportional to your confidence. As
you become more versed in deal evaluation and understanding of the risks
and costs associated with common problems, the better your confidence
can be in your estimate.</p>

<p>As an example, if you were a licensed contractor, you could more
confidently make estimates of issues with the home that would be
uncovered by a home inspection. This would make it less risky to forgo
some of the diligence others might need to apply. However, because you
had not as thoroughly evaluated the home as you would otherwise, the
deal would need to be better to make up for the uncertainty. A more
extreme example are homes bought at “courthouse steps” auctions -
effectively sight unseen. To maximize the chances of making money on
such deals, we need to be confident that the price reflects the
uncertainty of a property that has not had any diligence performed.</p>

<p>One pitfall here is our own inability to estimate the true confidence of
our own opinions. In other words, we as humans <a href="https://en.wikipedia.org/wiki/Dunning%E2%80%93Kruger_effect">tend to overestimate our
own
competence</a>.
Keep this in mind as you look for those fantastic deals: you might not
know as much as you thought! In general, developing reliable estimates
of expected value isn’t a task for beginners. For your first few deals,
strive to adhere to the previous rules to develop some intuition and
internalize the lessons. Once you’re more confident, you can consider
breaking the rules, but only when it makes sense.</p>

<hr />

<p>These rules have served me well over the last years, but they are by no
means comprehensive. Instead, they’re more like guideposts I use. If you
can follow them and ultimately incorporate them into your own thinking,
they are an effective way to improve the returns on your real estate
investments.</p>

restriction</a>, I’ve come to a
conclusion. In order to build a healthy relationship with food, we need
to recognize it for what it is: beyond being a necessity, food is often
an indulgence. By accepting and internalizing that fact, we can rebuild
the way we eat to produce the outcomes we really want - fitter
appearance and better health.</p>

<h2 id="indulgences">Indulgences</h2>
<p>Every luxury comes with a price tag, whether monetary or not. That price
tag is often the only criterion used to evaluate the transaction. You
see something you want, you check your bank account, find you can afford
it, and buy it. Great right? Unfortunately, with every transaction comes
second-order effects, indirect costs that can be difficult to evaluate,
even if we already know about them.</p>

<p>That new pair of shoes costs you <a href="http://amzn.to/2EBUY6I">hours of your
life</a>. The shiny new car <a href="https://www.nerdwallet.com/blog/loans/total-cost-owning-car/">extends your working
years</a>,
pushing retirement further into the future. The mortgage on the big
house puts you and your family closer to subsistence, making it harder
to recover from a loss of your job or any other financial setback. When
evaluating these types of transactions, we tend to focus on the outcome
(you, behind the wheel of the new car, turning every head in town) and
the immediate cost (whew, $40,000 seems pricey, but if i finance it…),
while ignoring these second order effects.</p>

<p>I’d argue that this is the <em>definition</em> of an indulgence: something we
crave, but that comes at a disproportionate cost to our future selves,
or those around us, or the environment, or anything else - again,
monetary cost and impact is just an easy example.</p>

<h2 id="food-as-indulgence">Food as indulgence</h2>
<p>In the context of this definition, food’s inclusion in the category of
indulgences is clear. The essence is well captured by the saying “once
on the lips, forever on the hips”: the second order effect of our lax
dietary choices is obesity, metabolic disorder, heart disease, and
everything else we already know about.</p>

<p>Food is unique in one way, though, and I think the distinction is what
makes unhealthy eating so commonplace in America: <strong>food has almost no
upfront cost at all</strong>. Soda, cookies, candy, fast food - these things
are all abundantly available at a price point that boggles. <a href="https://www.amazon.com/Oreo-Double-Chocolate-Sandwich-Cookies/dp/B0062Q5W54">Double Stuf
Oreos</a>,
one my sweet tooth’s favorites, clock in at a whopping 4200 calories per
bag, with each bag costing under $3! For what is effectively pocket
change, you can eat a phenomenally delicious taste explosion that
contains roughly <strong>twice</strong> a full day’s healthy calorie intake. I think
this is part of the reason you see Hardee’s and other fast food joints
crammed with contractors and other laborers: after a morning of physical
labor, you want the dopamine rush from eating delicious foods, and they
are available at a price even the poorest among us can manage.</p>

<p>Coupled with the gradual onset of the second-order effects of a bad
diet, these low prices put any and all food within reach of most
Americans. The outcomes we’re seeing are stark: <a href="https://en.wikipedia.org/wiki/Obesity_in_the_United_States#/media/File:USObesityRate1960-2004.svg">adult obesity rates
over 65% and increasing, with worsening rates among children as
well</a>.
Perhaps worse, data suggests that poverty and obesity are closely
related. Put another way, the people who will suffer the worst impact
from the second-order effects of a bad diet are the most susceptible.
For the most impoverished among us, life is largely devoid of luxury and
food offers a beacon of comfort, perhaps the only one within reach. This
thesis offers some insight into why <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3198075/">the relationship between poverty
and obesity might be
causative</a>; the
psychological toll of being poor itself may encourage worse eating
habits.</p>

<p>Though they may get the worst of it, it’s not only the poor. The phrase
“comfort food” perfectly captures the idea. When you’re sick, or sad, or
generally feel down, food offers a portal back into happiness and
luxury. Though the focus thus far has been primarily focused on the way
our relationship to food may be tied to widespread obesity, the very
same concepts are what make food universally amazing beyond its prosaic
position as a requirement to sustain life. This is precisely why we need
to become more mindful of the relationship, though. If we let our <a href="http://amzn.to/2EvudmW">fast
thinking</a> make the decision for us, we end up
ignoring the knock-on effects. Beyond combating bad diet habits, an
intentional relationship with food can make the joys of food that much
better.</p>]]></content><author><name></name></author><summary type="html"><![CDATA[After nearly a month of self-imposed dietary restriction, I’ve come to a conclusion.

<p>The <a href="http://steamcommunity.com/games/593110/announcements/detail/1464096684955433613">recent rash
of</a>
<a href="https://stripe.com/blog/ending-bitcoin-support">announcements</a> of
companies withdrawing support for Bitcoin payments is both totally
expected, given the dynamics of the cryptocurrency, and in my opinion a harbinger of
the end of Bitcoin as a payments system. More broadly, the combination
of the  validation timeframe for a given payment, the highly volatile
BTC-to-fiat price, and the resulting contention for payment validation
makes for an environment where it just doesn’t make sense to buy things
with Bitcoin, particularly if those things are relatively inexpensive.</p>

<p>On the consumer side, you are getting your goods in exchange for not
just the traded value of your BTC, but also the opportunity cost you’re
sacrificing to use them today instead of holding them until tomorrow.
For sellers, the trade is even worse - you need fiat currency to run
your business and pay your bills, so you need to accept the transfer and
convert it as quickly as possible. You therefore want to get it validated
immediately, but this means paying more in miner fees. If it
doesn’t get validated fast enough, however, the price difference between
the BTC transferred and the fiat price will be too wide. This
situation makes Bitcoin untenable as a medium of exchange. In some
ways, it’s a victim of its own success: even if there wasn’t a
speculative surge in price, this issue would likely have still come up
as more merchants joined the system, increasing validation times.</p>

<h2 id="bitcoin-as-a-store-of-value">Bitcoin as a store of value</h2>
<p>Bitcoin as a store of value is much more interesting.
It shares many characteristics with gold: scarcity, liquidity, and no
<a href="https://en.wikipedia.org/wiki/Credit_risk">counter-party risk</a>. Unlike
gold, it has no threat from <a href="https://gizmodo.com/this-mining-company-plans-to-land-on-an-asteroid-in-thr-1785112235">extraterrestrial
mining</a>.
Also unlike gold, it is infinitely subdivisible. There is no obvious
reason it would be tied to market performance, so it serves as a
reasonable hedge. The mind share and brand it commands means that it
already has quite a lot of stored value.</p>

<p>Assume Bitcoin fails entirely as a medium of exchange. Where can it go
from here? Let’s look more closely at gold as a comparison point. This is not
a perfect match, because gold has some utility beyond being a store
of value, such as jewelry and industrial applications, but it should
provide a good order-of-magnitude estimate.</p>

<p>An estimated <a href="https://www.gold.org/about-gold/gold-supply/gold-mining/how-much-gold-has-been-mined">187 kilotonnes of
gold</a>
has been mined. As of today, the gold exchange rate is $43.38/g, or $43,381/kg. That
means the world’s supply of gold is worth about $8.1T. Of that, roughly
20% is attributed to private investment - that’s about $1.6T.</p>

<p>Bitcoin has a <a href="https://en.bitcoin.it/wiki/Controlled_supply">fixed
supply</a> of 21M BTC. Let’s
assume that Bitcoin becomes as popular a store of value as gold, and
thus has a total supply value of $1.6T. In that case, each BTC would be
worth about $77,000. More realistically, it would split that market
share with gold and other stores of value. Nevertheless, a price of
$50,000 per BTC seems acceptable to me, and even $100,000/BTC doesn’t
seem wildly outrageous.</p>

<p>One implication is that, even if Bitcoin completely fails as a medium of
exchange, it could still have quite a bit of headroom on the price due
to its utility as a store of value. In that case, the prices would not
be wholly speculative.</p>]]></content><author><name></name></author><summary type="html"><![CDATA[Bitcoin as a medium of exchange The recent rash of announcements of companies withdrawing support for Bitcoin payments is both totally expected, given the dynamics of the cryptocurrency, and in my opinion a harbinger of the end of Bitcoin as a payments system.

People have a strange
compulsion-cum-arms race to give gifts, to the point where the gifts
given often lose the importance they should have. Who hasn’t been guilty
of this - in the panicked moments before Christmas, buying some silly
bauble because you can’t think of anything better? I know I have, and as
a quasi-minimalist, it bothers me.</p>

<p>What could we do instead? I’ve come up with a few things that can
improve gift giving, things that I myself am going to try to implement.</p>

<h2 id="1-decouple-gift-giving-from-dates">1. Decouple gift giving from dates</h2>
<p>A prime motivator for buying that unnecessary (and often unwanted!) gift
is an impending event. With your partner’s birthday in three days, what
can you get her?! Better run to Walmart and buy something disposable,
wasteful, and unneeded! I think this motivation to give a gift is
artificial. Instead of getting them a gift, write them a letter. Open
yourself up to them. Give them some of yourself.</p>

<p>Instead, give gifts as the <em>gift</em> presents itself. People are constantly
telling us about things they secretly want or need, but won’t get for
themselves. These are exactly the perfect gifts for someone. When you
hear a declaration like that, buy the person the gift! Don’t wait!</p>

<h2 id="2-give-intentionally">2. Give intentionally</h2>
<p>Closely related to the last point, stop giving people things just to
give them something. Instead, only give people things they truly want or
need. It’s better to not give anything than to give something unwanted.
In my opinion, the best gift is something the receiver deeply desires,
but is too much of a luxury for them to get for themselves. As an
example, I mentioned wanting a small fountain pen to carry with me. I
had a <a href="http://amzn.to/2Dvk0pV">Fisher Space Pen</a> when I was younger, and
loved it, but didn’t love the ball-point. I did a little research and
discovered the <a href="http://amzn.to/2FXc7YX">Kaewaco Liliput in copper</a>. What
a beautiful pen! And it’s the same size as a Fisher! The price put me
off though. What pen is worth $100?</p>

<p>My best friend got me one for christmas. And a Fisher. He was listening,
and he found me a perfect gift. You too can give perfect gifts! It’s
simple - just start listening to your friends talking about things they
want. Not everyday things, but things they desperately want but won’t
get for themselves. I’ve started keeping a list, for when I inevitably
fail to follow rule #1.</p>

<h2 id="3-give-best-in-class-presents">3. Give best-in-class presents</h2>
<p>Avoid giving throwaway gifts, which are wasteful and exploitive, by
instead giving gifts of very high quality. Think about this: of the
things you own, how many are the best in the world? Or even the best in
their given class? When faced with an opportunity to give someone a
gift, give them something they’ll give to their children: something best
in class. Things in this category tend to last forever, and tend to get
used and enjoyed more than more disposable things. They also tend to be
more expensive. The price of these gifts can actually serve as a strong
reminder not to impulse-buy things, but instead to follow rule #2 and
give mindfully.</p>

<h2 id="4-give-consumables">4. Give consumables</h2>
<p>If you find yourself in a situation where rules #1 and #2 can’t apply,
and you don’t have time for finding a best-in-class present that fits,
don’t reach for disposable stuff like consumer tech, cheap clothes,
plastic household items, or otherwise. Instead, grab some consumable
luxuries - coffee, cheese, booze, chocolate, or the like. Consumables
like these are almost universally appreciated, and don’t end up in a
thrift store (or worse, landfill). With a bit of thought, you can take
this concept wider and give an amazing gift of nothing but consumables.</p>

<p>As an example, my mother built me a “wine party in a box” - 12 bottles
of wine, hidden in paper bags, with pairing notes, tasting cards, and
the like. It wasn’t just 12 bottles of wine, it was an evening of fun
with my friends. And the gifts don’t need to be nearly as lavish - my
sister got me a bottle of champagne, some fresh oranges, and a handmade
citrus reamer.</p>

<h2 id="5-give-giving">5. Give giving</h2>
<p>This doesn’t always apply, but a good gift for some people is a donation
in their name to a cause they are passionate about. In some ways, this
is the anti-gift of the impulse buy Walmart gift: instead of exploiting
resources and people, and instead of clogging the landfill with yet
another unneeded or broken widget, it serves double purpose, as both
meaningful gift <em>and</em> benefit to society.</p>

<p>In 2018, I’m trying to do all these things, for my sake, for the sake of
the environment, but also for the sake of the recipients of the gifts
themselves. By bringing intention to the gift-giving process, it becomes
much more meaningful to everyone involved.</p>]]></content><author><name></name></author><summary type="html"><![CDATA[Gift giving is an interesting and emotional topic.

I started thinking about
the concept after listening to <a href="http://okdork.com/jason-fried-robots-watches-and-not-sweating/">Noah Kagan’s podcast with Jason
Fried</a>.
Jason, a lover of cars, was asked about his favorite cars. He
answered Aston Martin, and one of the reasons he gave was Aston’s
dedication to what he called authenticity of materials - if it looks
like wood, it is wood; if it looks like metal, it is metal. In contrast,
in many cars, even high-end cars, chrome elements are really
chrome-plated plastic; woodgrain is veneer. Jason talked briefly about
the cost of this authenticity of materials. The cars still need to be
largely handmade, and of course are rather expensive.</p>

<p>More generally, this is an example of what I’d call <em>authenticity of
design.</em> Authenticity of this type is imbued in a made thing by the
creator, and the creator’s dedication to authenticity is what prompts
it. Therefore, authenticity of design is externalized. Beyond
authenticity of materials,
<a href="https://en.wikipedia.org/wiki/Skeuomorph">skeuomorphs</a> - design elements that evoke
other made objects of a different type - are an example of
inauthenticity of design; <a href="https://en.wikipedia.org/wiki/Affordance">affordances</a></p>
<ul>
  <li>if it looks like you interact
with something, you can - are an example of authenticity of design.</li>
</ul>

<p>A week or so later, I was listening to another podcast, <a href="http://tim.blog/2017/02/02/lessons-from-warren-buffett-bobby-fischer-and-other-outliers/">The Tim Ferriss
show with Adam
Robinson</a>.
Adam and Tim discussed battling depression,
and Adam explained that one of the breakthroughs that helped him emerge
from depression was also one of authenticity - his authenticity of
self-image. In my own words, the idea is that we are often so focused on
selling ourselves, on creating an image of ourselves, that we embrace
that image regardless of how well it reflects who we really are. This
creates an internal conflict, because if we believe in a false image of
ourselves - an inauthentic image - we compare our real actions and
feelings to it and find ourselves lacking. This discord likely affects
people differently, but I imagine one of those ways is depression and
self-loathing.</p>

<p>I’d characterize this type of authenticity as <em>authenticity of self.</em>
Authenticity of this type is both representative and the creation of the
same maker - it is about one’s own representation of one’s self. In this
way, it is internal authenticity, in contrast to the external
authenticity of design. I’ll discuss some more examples of this type of
authenticity below.</p>

<p>One thing I find interesting about both of these types of authenticity
is that they are both of <em>intrinsic</em> value, sometimes to the detriment
of extrinsic economic interests. By that I mean that often the world
around us often rewards inauthenticity. As a result, efforts to remain
authentic must be motivated by an intrinsic force, an assignment of
value to authenticity itself. As I write this, I feel like there is an
almost moral overtone to the entire concept, though I don’t feel like
authenticity (or its lack) is really related to ethics, which are about
our relationship with those around us. Instead, I feel like authenticity
is kind of like an inward-facing morality.</p>

<p>Since hearing the discussions above and thinking about them for a while,
I’ve come to see authenticity, and the struggle for authenticity,
everywhere, and particularly in business. Companies often market
themselves as something they aren’t truly. Tech companies in particular
often like to pretend that their work is wildly innovative and
groundbreaking, and that they are leading the charge in some new
direction. In reality, many of those companies, particularly larger
companies, do very little innovation. Instead, they provide relatively
reliable if somewhat prosaic software with great account involvement and
great support. These benefits are super valuable, so why the
inauthenticity? In my opinion, it costs these companies quite a lot,
both in terms of dollars to maintain this facade, and in terms of a
deeper conflict in the organization itself - akin to the internal
conflict we feel when we are inauthentic with our image of ourself. This
conflict manifests in disjointed strategy and wasted efforts as the
business units, products, and employees seek to find relevance within
the image the company presents for itself. On the other hand, the
benefits are dubious at best - who is being fooled? Surely not the
customers, at least the ones you can retain.</p>

<p>I think companies should seek to be authentic in their marketing. If it
looks like wood, it is wood; if it looks like metal, it is metal; if you
say you’re innovative, you are; if you say you support your products
rabidly, you do. Instead of presenting your company as something you
aren’t, present it as what you <em>actually are</em>. If you want to <em>be</em>
something else, become it (or a least invest in becoming it) before you
start saying it. Incidentally, this is just as true for individuals as
it is for companies. Say what you are, and be who you say you are.</p>

<p>Unfortunately, as I said above I think the value of authenticity is
first an intrinsic one. This means that companies in particular, but
also individuals to some extent, are often incentivized to operate
outside of authenticity. Authenticity costs something as well, and that
cost combined with the frequent external reward for inauthenticity make
it hard to stay the course. However, I think the rewards are much more
long-lasting than the external rewards. These rewards are both internal
and external.</p>

<p>Externally, authenticity is often reward by rabid enthusiasm from
others, as in the case of Aston with Jason Fried. People tend to admire
these products, want to talk about them, want to show them to others. I
think a lot of the recent popularity in buying higher quality products
(selvedge denim, or Darn Tough socks, for example) is a reflection of
the market desire for authenticity, and possibly even a backlash against
inauthenticity. For companies where metrics like net promoter scores are
beginning to take such an important position, this kind of reward can
recommend authenticity over the more fleeting reward for inauthenticity.</p>

<p>Beyond external rewards, maintaining an authentic image promotes an
inner harmony of sorts. I think this is what Adam Robinson was referring
to, and I think it extends beyond just ourselves to our organizations at
large. In many companies, a mission statement serves as a good starting
point, but I think it’s important for the <em>entire company</em> to reflect
the authentic value of the company internal as well as externally - from
leadership to HR to PR to marketing to sales to engineering to
operations. When everyone in the company is aligned, and everyone is
saying the same thing, and the thing they are saying is an honest
description of what the company is, every action that is taken is
on-mission. Without that, a mission statement is as divorced from
reality as the marketing. When a company devotes itself to authenticity,
nothing is a lie and nothing is pretense.</p>]]></content><author><name></name></author><summary type="html"><![CDATA[I’ve been pondering the idea of authenticity.

item off my <a href="/35-list.html">35 by 35 list</a> (and <a href="/blog/post/2016-roundup/">yearly
goals</a>) by sending my first outdoor
V8-grade boulder problem, <em>Right Exit to Fontainezoo</em>, alternatively
called <a href="https://www.mountainproject.com/v/w-goes-to-fontainzoo/110262654">W Goes to
Fontainzoo</a>.
It represents over a year of effort and attempts, a very <a href="http://www.hotaches.com/climbing-films/e11/">Dave
MacLeod</a> approach to
climbing. Since I first attempted it, I’ve worked on my climbing roughly
3 days a week on average, including a period with a torn pulley.</p>

<p>Ultimately, I succeeded on this problem (“solved” it, if you will) with
a reductionist approach quite similar to the root cause analysis of
software failures I’ve done: in the event of a failure, ask why until
you arrive an issue you can address directly. Start at the beginning of the climb, try your hardest,
fall off. Why did you fail? Because my foot slipped. Why? Because my center of gravity was too far to the right. Why?
Because I was letting my core sag. Pick yourself up, try again,
conscious of keeping your core tight.</p>

<p>I performed that process for
almost every move of the climb, which was two grades harder than my
previous hardest ascent when I started. By reducing the climb to 
a series of fundamental, actionable improvements, I was able to make progress,
despite initially feeling as though the end result was out of reach. Even today, a
year later and much stronger, I subtly adjusted my footwork and my angle
of attack on holds. And today, all the pieces came together, and it was
beautiful.</p>

<p>I’m struck by the similarity to building software and processes. Deliver
a release to customers, find out it’s failed for some case. Why?
Because… Why? Because…
Why? Because… Implement the changes at both the software level (so it
works next release) and at the process or team level (so that the
problem doesn’t happen again. No wonder so many climbers work in
software.</p>]]></content><author><name></name></author><summary type="html"><![CDATA[I’m very happy to announce that today, Feb. 4, 2017, I crossed another item off my 35 by 35 list (and yearly goals) by sending my first outdoor V8-grade boulder problem, Right Exit to Fontainezoo, alternatively called W Goes to Fontainzoo.

interesting themes I’ve picked out is the idea of intentionally building
the network of people with whom you interact, with the goal of
surrounding yourself with people who can inspire and teach you. I am a
big believer in the value of networking, and I try to follow up and stay
in touch with people I think bring value to my life, but I’ve previously
taken a more passive approach, meeting people at conferences and in
chance encounters.</p>

<p>The theme I’ve noticed among high achievers is that they not only see
the value of networking, but they <em>actively and intentionally</em> build
their networks. Instead of waiting to meet someone interesting, they
apply systems to meet these people sooner and follow up with them to
build their relationships. By building out their networks in this way (and actively
pruning them), they wind up with relationships and interactions that
help them achieve their goals, whatever they might be.</p>

<p>Obviously, seeking out specific people who are high achievers or
innovators in the area of your goals is a direct way to do this.
However, I propose (and am seeking to implement) a second approach as
well: <em>greedily look for people who are inspiring among your existing
network</em>, regardless of why they are inspiring. Ask your existing
network three simple questions:</p>

<ol>
  <li>Who is the most interesting or inspiring person you know?</li>
  <li>Why are they interesting or inspiring?</li>
  <li>Can you introduce me to this person?</li>
</ol>

<p>If you think of the directed approach of connecting with high performers in the area
of your goals as <em>optimizing</em> your network, this approach provides a
complementary <em>exploration</em> component. As I’ve learned from my studies
in <a href="https://en.wikipedia.org/wiki/Reinforcement_learning">reinforcement
learning</a>,
striking this balance between optimization and exploration is key to any
endeavor for which we do not have perfect information; building our
networks to enrich our lives certainly falls in that category. Another
analogy in my own life is my efforts to read books and papers outside of
computing and software. These books and papers often inspire
cross-domain ideas that produce much better results in the original
problems I was seeking to solve. Likewise, interacting with interesting and inspiring people, regardless
of where their success lies, broadens our view of the world and enriches
us in ways that single-topic interaction cannot.</p>

<p>I challenge you, and myself, to get out and ask someone in your network
for an introduction to the most interesting person they know. Have a
coffee or beer with that person and talk to them about their lives,
their habits, and what they’re passionate about. Offer to help this
person in some way if you can. Build out your network to be both deep
<em>and</em> broad, and surround yourself with interesting, inspiring people.</p>]]></content><author><name></name></author><summary type="html"><![CDATA[This may be a mild form of apophenia, but any time I see a recommendation or idea several times within a short period of time, I take note.
