I’ve used the service for years, mostly to keep track of books I’ve read or want to read. There’s some nice recommendation features and integration with social networks so I have some notion of what other friends are reading. All in all it’s a good service, and I wish I had thought to build it first!</p> <p>What I <em>don’t</em> like about Goodreads is their annual reading goal. You’re strongly encouraged to specify how many books you’ll read in a year, and on subsequent logins you’re informed of your progress. For 2017, I set mine at 30 and fell a few books short.</p> <p>On the surface this seems like an honorable undertaking: get people to read more (and consequently use the network more). But does this method work? Is “books read” the metric we should be optimizing for? Probably not. This thinking encourages people to read as many books as possible, not caring about quality or relevance to their lives but simply trying to hit a target number. It makes books disposable, notches on a belt rather than works of art. It also suggests people should read faster, not taking the time to digest, debate, and have an overall dialogue with the book.</p> <p>On some level this reading goal definitely messed with my head. I grew up very much a perfectionist, terrified of failure and focused more on grades than learning. So much so that one time in fifth grade I got a 60 on a quiz (the horror!) and broke down in tears. While I’ve mellowed out quite a bit since then (philosophy and alcohol probably helped the most), my basic programming still has that instinct to hit arbitrary goals without thinking about why.</p> <p>So for people like me, these goals do more harm than good. I’ve instead tried to focus more on systems when thinking about achievement. <a href="https://lifehacker.com/dilberts-scott-adams-on-willpower-have-systems-not-go-1659865519">Scott Adams</a> talks about this idea at length. <a href="http://investorfieldguide.com/growth-without-goals/">Patrick O’Shaugnessy</a> also has a nice treatment of the idea. In short, don’t <em>dwell</em> on external metrics. You can still use them as a measurement tool, but ultimately your focus and motivation should center on creating habits and routines that increase your probability of success.</p> <p>Paired with this idea is the notion of stoicism. Most people think of stoics as lacking emotion. I think of it more in this context as not being emotionally impacted by external events. You put your work in, you prepare as best you can, and you let the chips fall where they may. I love this approach because honestly, what else can you do? Be aware of what you can control, and try not to worry about the rest.</p> <p>So what would a system of reading look like? Instead of setting a goal of <em>m</em> books to read in a year, why not develop a habit of reading <em>n</em> pages a day or week? Or maybe even set an “anti-goal” of a “books read limit” for the year. Let’s say the max books is at 12 (one book per month). Then you’re forced to choose <strong>only</strong> a dozen books to read all year. Under that constraint, aren’t you more likely to be very judicious about the books you read? I imagine you’d take your time with the books too. Really digest them and converse with them since hey, what’s the rush?</p> <p>Maybe you operate better with goals. Ultimately it’s up to you to figure out how to achieve what you want. But it’s important to not let things like software, social networks, or any external forces manipulate your thinking.</p> Fri, 19 Jan 2018 00:00:00 +0000 http://www.josephpconley.com/2018/01/19/badreads.html http://www.josephpconley.com/2018/01/19/badreads.html High-Leverage Development with Giter8 Templates <p><img src="https://images.gr-assets.com/books/1427583285l/25238425.jpg" /> <img src="https://images.gr-assets.com/books/1347800461l/324750.jpg" /></p> <p><a href="https://twitter.com/edmondlau">Edmond Lau</a> talks a lot about leverage in his book <a href="https://www.goodreads.com/book/show/25238425-the-effective-engineer?from_search=true">The Effective Engineer</a>, a term he borrowed from Andy Grove’s <a href="https://www.goodreads.com/book/show/324750.High_Output_Management?ac=1&amp;from_search=true">High Output Management</a>. Both are excellent reads, especially for programmers looking to maximize the impact they have on their teams. The term <em>leverage</em> gets to the heart of this. It describes activities that create a disproportionate amount of value. This feels like a much more elegant description than “10x/rockstar/ninja developer” or whatever cliche that stokes the egos of the programmer-gods. It places the focus on <em>output</em>, where it belongs!</p> <p>Some examples of high-leverage activities Lau mentions include:</p> <ul> <li>improving the onboarding processes for new hires via tutorials, documentation, and notebooks (i.e. labs)</li> <li>creating tight feedback loops to quickly validate ideas (e.g. use a REPL or a notebook!)</li> <li>writing tools to make you and other developers more efficient</li> </ul> <p>In this spirit, I’ve created a <a href="http://www.foundweekends.org/giter8/">Giter8</a> template to show how to <a href="https://github.com/josephpconley/spark-seed.g8">create an SBT-based Spark project</a> with the following accouterments:</p> <ul> <li>utilities for logging and writing dataframes in common formats</li> <li>configuration via <a href="https://github.com/typesafehub/config">Typesafe Config</a></li> <li>building the fat jar via <a href="https://github.com/sbt/sbt-assembly">sbt-assembly</a></li> <li>release support via <a href="https://github.com/sbt/sbt-release">sbt-release</a></li> <li>support for running your Spark job in Intellij</li> </ul> <p>This has saved me a significant amount of time in starting new Spark jobs or testing out quick proof-of-concepts.

That was my biggest takeaway from reading <em>Sapiens: A Brief History of Humankind</em> by Yuval Noah Harari. He does a masterful job in articulating the history of our species and the forces that guided our culture. His narrative encourages us to reflect on our own role in the universe and try to understand what’s meaningful in life and what isn’t.</p> <p>I was amazed to learn that there were multiple different human species, and that ours “won out” due to the creation of myths that effectively organized large numbers of people. Surprisingly, similar myths still persist today. Companies, money, religion, they’re all inter-subjective fictions that govern our daily lives. However, just because these fictions don’t exists <em>a priori</em> in nature doesn’t mean they aren’t important. It’s just helpful to remember that fictions like money are built on trust, and in rare cases (like the 2007 financial crisis) that faith can be strained or even broken altogether.</p> <p>I was also surprised to learn that the advent of farming is actually “History’s Biggest Fraud”. You’d think that cultivating farmland would be a boon to our ancestors, yet farming was much harder work than foraging. Relying on one staple crop provided a less balanced diet than the varied intake of foraging. Most farmers hoped to reach a state of affluence by achieving food surpluses, yet this just lead to a population growth that created more mouths to feed. Never forget second-order effects!</p> <p><img width="700" height="450" src="/assets/wheat.jpg" alt="Ancient Egyptian mural – Wheat harvest" /><br /></p> <p>One other oddity I’ve often wondered about: how did a tiny island in Europe conquer so many global territories? England had, above all others, a great desire to learn and cure its ignorance using the scientific method. This quest to improve knowledge, in conjunction with a deep national pride and desire for conquest, led the country to fund risky expeditions to all corners of the globe, expanding their empire.</p> <p>I think I most appreciated the power that the individual has in our current age. We’ve advanced technologically by leaps and bounds, and as most dystopian books or movies will tell you, with that great power comes a great responsibility. Climate change is real folks. We have not been very hospitable guests of this planet, exterminating entire species of animal wholesale and polluting our environment. Yet through our ingenuity, we have the ability to develop renewable sources of energy, preserve endangered species, and even one day colonize other planets like Mars (really hoping to live long enough to see that one). Yeah Science!</p> <iframe width="700" height="450" src="https://www.youtube.com/embed/WoKvRzOw5hg" frameborder="0" allowfullscreen=""></iframe> <p><br /></p> <p>Harari concludes with a thoughtful exploration of human happiness. Despite our progress and relative prosperity, we seem more discontented than ever. He cites research that shows that money and good health provide diminishing returns for happiness, and offers Buddhism as an interesting path to ending suffering. His final line, though, strikes a note of caution in his beautifully phrased warning, “Is there anything more dangerous than dissatisfied and irresponsible gods who don’t know what they want?”</p> <p><em>Sapiens</em> is a great read for people from all walks of life. Harari touches on a few dozen fields of study like history, biology, economics, philosophy, political science, computer science, and psychology to name just a few. His work is a great reminder of where we come from and where we might be going. He notes that “History has a wide horizon of possibilities, the vast majority of which don’t get realized.” He reminds us of our own possibility as a species and that today, more than ever, we have the power to shape it.</p> Wed, 23 Nov 2016 00:00:00 +0000 http://www.josephpconley.com/2016/11/23/the-power-of-myth.html http://www.josephpconley.com/2016/11/23/the-power-of-myth.html A Crisis of Imagination <p><a href="https://www.goodreads.com/book/show/22889809-stress-test" target="_blank"><img src="https://d.gr-assets.com/books/1418769295l/22889809.jpg" /></a></p> <p>I found it difficult not to admire Secretary Geithner after reading <em>Stress Test</em>. He’s colorful, pragmatic, a realist who focuses on substance over optics. He’s clearly a bright guy, rising fast in the world of finance despite a lack of formal education in the subject. He’s also a great teacher, “marinating” the reader in economic terminology (one of many Geithnerisms). Yet his most endearing quality is his spirit for public service. He was one of the “first responders” to the Great Recession, and I believe that his efforts and the efforts of others helped to dampen the effects of the crisis. While it’s difficult to imagine how much worse off we would’ve been, we owe it to ourselves to at least suspend our populist outrage over the Wall St. bailouts and take a serious look at the crisis and its aftermath as this could most certainly happen again in our lifetime.</p> <p>The Great Recession wiped away nearly $15 trillion in household wealth. Unemployment peaked at 10%, and we’re still feeling the effects today. And yet most people ask, why didn’t anyone go to jail? Because this was ultimately a crisis of imagination. No one imagined in 2007 that housing prices would crater. No one foresaw how the complicated derivatives market would unwind and go beyond investment banks to affect other large financial institutions and insurers. No one anticipated the need to keep capital reserves, opting instead for high amounts of leverage and short-term, runnable funding. This was an insanely complex crisis that is <a href="http://www.econ2.jhu.edu/People/Ball/Lehman.pdf">still being debated</a> and <a href="https://www.coursera.org/learn/global-financial-crisis/home">studied</a> today, almost a decade later. It’s clear that its causes were too complex to assign blame to a few bad actors.</p> <p>Given this complexity, it’s not surprising that the average person doesn’t appreciate the work that government officials like Geithner, Ben Bernake and Hank Paulson did to prevent an economic collapse. This, too, is another failure of imagination. While it’s reasonable to object to certain aspects of the response, like the failures of Lehman and Washington Mutual, it’s difficult to argue that these individuals didn’t act in good faith to resuscitate an economy that was on life support. It’s equally tough to question their credentials, as Geithner spent most of his career at the IMF helping countries deal with crises, and Bernake’s academic career focused on the Great Depression. I suspect that economics itself is partly to blame, as it’s difficult to see the real-time effect of policy until months or even years after the fact.</p> <p>Yet despite these ambiguities, we have concrete evidence that the response was mostly positive. Most of the bailouts have been repaid with a profit to the taxpayer. We can see from the recent economic troubles in Europe that punitive haircuts and excessive austerity, things Geithner fought against and successfully avoided, has led to unnecessary economic stagnation in the Eurozone. The stock market has returned to pre-crisis levels, and then some. The financial system is now stronger after the increased capital requirements of the stress tests and the creation of programs like the Consumer Financial Protection Bureau which help to restore fairness to the markets. Whatever your opinion of these officials, it’s clear that the country is in a better place than it was in 2007, and we’re better prepared for the next crisis.</p> <p>Unfortunately, these public figures have been mostly vilified for their efforts, accused of saving the arsonists on Wall St. while ignoring the common people on Main St. That’s the reality of a crisis. Systemically important institutions had to be saved to protect the whole system. And that’s certainly a thankless task, to do something you know is right when it’s unpopular. But history will be the ultimate judge, and I think it will ultimately look kindly on the efforts of these individuals.</p> <p>I was very inspired reading Geithner’s first-hand account of the response to the Great Recession. His story highlights the importance of public service, and shows how a “small group of thoughtful, dedicated citizens can change the world” <a href="http://www.brainyquote.com/quotes/quotes/m/margaretme100502.html">1</a>.
