The Free OS

So I recently bought a game I was very exited about playing–I’d hoped to write a review of it here in the next week or two–but when I downloaded it I discovered that I couldn’t play it because my operating system was too old.  “Great,” I’m thinking, “so instead of costing me ten dollars on Humble Bundle, it’ll cost me three hundred or something at a Mac store?”  Having to buy new operating systems every time the one you’re running gets out of date has always been a scam perpetuated largely by Microsoft’s monopoly on the OS market, but I had never felt it so strongly before.  The introduction of alternatives like Chrome OS and the proliferation of always-up-to-date web applications has made this business model seem not only inconvenient and forced, but unnecessary as well.  Then, just as I was thinking I would finally bite the bullet and at least see if I could get a cheaper second-hand copy on Ebay or something, I discover to my delight and surprise that Apple’s newest operating system, OS X Mavericks (guess they finally ran out of cool-sounding cats?) is available to download free on the app store!  All hail the Age of the Internet!  I only hope Microsoft has the courage and intelligence to follow suit with their next operating system.

Now, if you’ll excuse me, I’m going off to play Gone Home.  Look forward to a review of it here in the coming weeks!

My New Year’s Resolution: Being, not Doing

It’s no secret that most new year’s resolutions fail.  The reason is less well-known: most people resolve to do something differently in the coming year (e.g. lose weight, improve their relationships, get a raise), but make no concrete or detailed plans for how to do it.  The most effective new year’s resolutions are not vague aspirations, but commitments to specific habits.  The reason this works is threefold: first, specific goals are better than vague ones because they let you measure your progress.  If you resolve merely to “eat better”, it can be difficult to tell if you’ve succeeded.  (Better than what?  What does “better” mean?)  If you resolve, on the other hand, to lose 10 pounds (and keep them off–another common pitfall of new year’s resolutions), you have a specific measure of success.

The second reason specific habits are better is the habit part: changes are more effective if they’re consistent.  In addition to specific measures of success, goals that can be broken down into smaller pieces and made into a routine are more effective, because once they’re routine you no longer have to spend conscious effort on them.  Defaults have incredible power for this very reason, and making a commitment into a routine takes advantage of that power.  A new behavior done once is an exception–a new habit becomes part of who you are.

This leads me to the last, and possibly most important reason why commitments to specific habits work better than vague promises of improvement: they act to alter not just your behavior, but your self-image.  This is the same thing that makes hypnosis (and, to a lesser extent, self-affirmations) effective: it changes not just your behavior, but your fundamental conception of who you are.  This is deep magic: a behavior or commitment affected for someone else’s sake will never be as strong as a change in belief.  The most effective way to make a change in your life is to start thinking of yourself as the kind of person who makes that change.  In that sense, then, the most effective resolution is not to ask yourself what you want to do differently, but who you want to be differently.  To that end, here’s my new year’s resolution for 2014:

I resolve that I am an

  • Attentive
  • Hardworking
  • Ambitious
  • Creator[1]

I chose to be Attentive because I’ve noticed recently that I tend to operate on autopilot a lot, not paying full attention to whatever I’m working on.  Sometimes that’s okay, if I’m paying attention to something else (presumably something more important) instead.  But more often these days, I find myself running on autopilot just because I can, and that’s simply lazy.  So, I am resolving to be someone who gives my full attention to whatever it is I’m working on at that moment.

I chose to be Hardworking for similar reasons.  In college, one of the biggest lessons I learned was how to procrastinate on a deadline–to my misfortune, I discovered that I could often get away with simply not doing a lot of the work, as long as I did well enough on tests and other assignments to keep my grade up.  Unfortunately, that’s not how the real world works: if I miss a deadline at work, the project doesn’t just go away at the end of the semester.  So, I’m resolving to be someone who works hard to accomplish whatever I commit to, and to do my best to get it done on time.

I chose to be Ambitious because I want to make an impact on the world someday, and because I look up to and admire people with similar ambitions.  It may be idealistic to want to singlehandedly change the world for the better…but then, only idealists ever have.  So, I’m resolving to be a person who has high expectations for myself, and who’s never satisfied by the status quo.

Finally, I chose to be a Creator because I wanted to re-affirm my commitment to art and invention.  When I was a small child I wanted to be an inventor–someone who brought their imaginings into the world of reality.  As I got older I realized that literally being an inventor was not the only way to do that: it was possible with art and science as well.  What’s important to me is not necessarily the method by which I influence the world around me, what’s important is merely that I do.  So, I am resolving to be a person who uses their mind and hands to make their thoughts visible to the rest of the world, to actively change it for the better.  In other words…to be an artist.

What are your new year’s resolutions?

Digging through some old emails I found an article I’d read years ago that said basically this same thing, only better.

Why Do Mirrors Reverse Left and Right?

When you see your reflection in a mirror, why does your right become its left, but top and bottom stay the same?  I’ve seen this question answered a number of different ways, but the explanation that makes the most sense to me is also, I think, the simplest: mirrors don’t reverse left and right.  They reverse front and back.

Since “left” and “right” are subjective,[1] let’s simplify the discussion a little: imagine that you’re facing due north and there’s a mirror in front of you.  If you jump up, your reflection will also jump up–no reversal.  If you step one foot sideways, to the east, your reflection will also step one foot to the east: not reversed.  But if you step south, away from the mirror, your reflection will move north–the opposite direction.

The reason mirrors seem to reverse left and right, but not up and down, is because when looking at our reflection we automatically imagine ourselves in their position–that is, turned around both left-right and front-back.  This habit comes from a lifetime of interacting with other people and having to interpret their “right”, “left”, “front” and “back” in terms of our own.  When we see our reflection, we reflexively identify it as another person, identical to us in every respect, except with all their features on the “other side”–e.g., a mole on the left side of your face is on the right side from your reflection’s “point of view”.  But it is not the mirror that makes this transformation–it’s us, when we mentally turn ourselves around and put ourselves in our reflection’s shoes!  We are mentally reversing our front-back and left-right, but the mirror reverses only the first.

Think about looking at yourself with a video camera.  Here, left-right and front-back are both reversed (if you’re facing your recording, that is–if you’re looking at yourself from the back then nothing will be reversed).  If you move towards the screen (e.g. north), your recording moves in the opposite direction (e.g. south); if you move to your right (e.g. east), your recording still moves in the opposite direction (e.g. west).  The same goes for text printed on a shirt: in a recording, front-back and left-right are both switched, just like they would be on another person, so the text is legible; but in a reflection, only front and back are switched, so–just like a transparency sheet viewed from the wrong direction–the text appears “backwards”.[2]  To prove that the text on your shirt is not reversed left-to-right in a mirror, you could remove the shirt and point it at a bright light so that you can read it from the inside (in other words, the back–but with the right sleeve still on your right and the left sleeve still on your left).  The text will look just like it does in the mirror: front and back reversed, but left and right the same.

Feeling enlightened?  Confused?  Got a better explanation?  Let me hear it in the comments!

Notes:

[1] As a child, I once asked my parents how people knew what side of the road to drive on, to keep from crashing.  When they told me “you drive on the right”, I was still confused–“whose right?” I thought.  It took me a while to realize that it didn’t matter–if you’re traveling in the other direction, “right” is on the other side.  This is not an intuitive idea.

[2] If the image I linked is confusing you, think about it this way: the text on the transparency is viewed from the front, so it is perfectly readable.  The mirror “sees” the transparency from the back, so from its perspective the text is reversed front-to-back (just as it would be if you were looking at the other side of the transparency).  But the mirror itself reverses front and back when it reflects the text back to you, so the reflection still appears legible because front and back have been reversed twice.

Always Be Testing

I recently came across an article by Jeff Atwood (of Coding Horror) on how to be successful. It opened with a line of advice that I really liked: “Always Be Jabbing. Always Be Shipping. Always Be Firing.” The idea behind this advice is that as long as you keep moving forward, no matter how much you suck you’ll eventually be successful.

I’d like to add another word of advice along these same lines: Always Be Testing.

My problem (and I’m guessing there are many of you out there who share this problem) is that it can be very easy for me to trick myself into thinking that I’m making something when I’m really not.  The degenerate case of this is errands like doing laundry, taking the dog for a walk, writing thank-you notes, organizing your desk, etc.  These are all legitimate things to be doing and they can be fairly important, so it feels much less like procrastinating than just sitting around on your butt playing videogames or watching TV.  But if you’re doing them in order to avoid other, more important work, then it’s still procrastination–only worse, because you feel like you’re getting something done.

Unfortunately, there are even more subtle ways to procrastinate while still feeling productive.  Perhaps the most insidious of all is the type of procrastination where you’re producing like crazy, but you’re not doing any testing.  Maybe you’ve written a 500-page book but are afraid to read it (let alone give it to anyone else to read).  Maybe you’ve been practicing an instrument in your basement for months, but you won’t let anyone listen to you play.  Or maybe you’ve written a few hundred lines of code without once actually running your program.  There are a number of reasons people do this, but probably the most common is fear of failure or rejection.  Well, the bad news is that you will face failure and rejection.  Your writing will be torn apart, your playing criticized, and your code broken in a dozen different ways.  Here’s the problem, though: without testing, producing is just an errand.  It’s something that has to be done, of course, but it’s not the most important part of building something.  Just as the most important part of writing is reading what you’ve written, and the most important part of architecture is construction, the most important part of programming is testing your code to make sure it works.[1]

What I really like about the “Always Be Testing” aphorism is that (along with the other three Jeff mentions) it’s applicable not just to writing or programming, but to life in general.  If you’re not making things, you’re not improving and you will never be successful–and if there’s no chance of something going wrong, then you’re not really making things.  Anytime you suspect you may be procrastinating by doing something that feels like work but really isn’t, ask yourself “what will happen if I mess this up?”  If the answer is, “basically nothing”, then you are procrastinating.  When you make something, you introduce a permanent change to the world–which means mistakes are permanent, too.  This can be scary, but it’s a necessary tradeoff: without the possibility of failure there can be no such thing as success.

So what does that mean in practice?  It means you should always have something that’s ready for an audience, even if that audience is just your closest friend, or you as your program’s first user.  For writers, it means constantly getting feedback on new revisions.  For architects, it means making scale models at each stage of the design process.  And for programmers, it means always having some small program working and complete enough that you can run it and see if it does what it’s supposed to.  Again, this isn’t just good programming practice, it’s good practice for life: start small with something tangible, then work your way up from there.

In the end, that’s all success really is.

Notes:

[1] Obviously, you still have to write the code first, and buildings need to be planned before they’re built.  My point is not that planning and preparing aren’t important, my point is that until your code works or you have a standing building or your art has an audience, you have not actually made anything–you have merely prepared to make something.  A shoddy building that’s nevertheless standing is infinitely better than a building that never gets made, no matter how perfect its design.

Dissolving Anna Karenina’s Paradox

Philosophers of art have a long-standing problem known as “the Paradox of Fiction“, also known as “Anna Karenina’s Paradox”.[1] The problem is generally presented thus (this is not a direct quote):

When we watch scary or touching (or exciting or funny) movies, we claim to be actually feeling the emotions the medium is meant to inspire. When Anna Karenina dies, we say we feel sad, in the same way we would feel sad if a friend told us their mother had died. If we later found out the friend had been lying, however, we would become angry instead of sad: this implies that we must believe in the truth of a situation in order to feel genuine emotion. Yet we know that Anna Karenina does not exist–her tragedy is a falsehood, but we still say it makes us feel sad. This presents a contradiction: either we are lying when we say we feel sad, or the kind of sadness we feel when we hear of the death of someone we know is a qualitatively different emotion than the one we feel when we witness the death of a beloved character. This seems to be supported by the fact that we do not engage in behaviors that would normally be associated with emotions such as fear, anger, or sadness when engaging with fiction: we do not run screaming from the movie theatre in terror when we see the monster approach the screen; we do not call the police when a character in a book is murdered; and we do not climb on stage to seek revenge if a character we like has been wronged in some play.

In short, the problem is that the emotions we feel when we engage with fiction seem to be different than the emotions we profess to be feeling.[2] Normally I would work up to my refutation gradually, but this is–I’m sorry–an incredibly stupid “problem”. The so-called “paradox” of fiction can be completely dissolved with just a few simple counterexamples. Continue reading

On Intelligence: A Theory of Thinking

On Intelligence is a book written by Jeff Hawkins[1] on the nature of intelligence, both artificial and natural. It’s an expansion of and answer to an age-old question I’ve referred to before: how do we think? What does it mean to be intelligent? What is consciousness? Might it be possible to create an intelligent machine? And if we could–what would that mean for society? In this essay I’ll attempt to describe his theory, its motivations, and how it can be a powerful and useful tool in any field–even if you’re not very interested in AI.

Time Travel: What Is It?

It’s common to think of time as though it were a medium one travels through in the same way one travels through space–as in, you can travel one meter through space, or you can travel one second through time. Popular science education reinforces this idea by telling us that time is just another dimension, like the three spatial dimensions of up/down, left/right, and front/back. Yet there seems to be a weird exception in that we can only travel through time in one direction at a constant speed, whereas we can travel through space in any direction and at any speed we like. What if that weren’t the case? What if time’s seeming constancy were simply a technical limitation that someday we could solve? What if we could travel in either direction through time, just as we can now travel through any direction in space? This is the “science fiction” conception of time travel, and although it’s an immensely fun idea that has enjoyed huge popularity for over a century, it rests on a false analogy: time “travel” is a complete misnomer. The seemingly one-way nature of time, and its interconnectedness with space, are foundational to our conception of what it means to “travel” somewhere at all–without them, the term becomes meaningless.

What Is the Purpose of Government?

This essay is a follow-up to a previous piece I wrote on the topic of Objectivism.

The role of government should be as small as possible–otherwise the friction of the necessary bureaucracy would just be a waste. But how small is that? Some hold that the only true function of government is to protect its citizens from the use of force through the military and the police; hard-line Objectivists sometimes advocate for the complete or near-complete elimination of government except for these duties. Yet I think this attitude is too narrow: military and police are one necessary function of government, certainly, but might there be others? To understand what government’s role should be, we must first understand why large-scale organizations and bureaucracies, including governments, exist at all.

The “Real World” Fallacy

The American institution of public schooling is considered one of our greatest strengths–but why?  What is the purpose of schools, and why do we force our children to attend them?  The response you’ll most often hear is that school prepares our students for the task they must all ultimately undertake of being successful, responsible adults–that’s what we usually mean by the term education.  Yet there is an odd contradiction implicit in this attitude: if the purpose of education is to prepare children for the “real world”, then why do we need schools?  It’s generally understood that the schools themselves are not the “real world”, so they must necessarily be artificial worlds: invented realities designed to shelter our children from the responsibilities of adulthood until they are “ready” for them.  It is no great secret that experiential learning is by far the most effective kind, yet the fierce irony of preparing our children for the “real world” by sequestering them from it entirely goes apparently unnoticed.  This idea of preparing our children to be adults by treating them like anything but–what I call the “real world” fallacy–is a perfect encapsulation of everything that is wrong with our current way of thinking about school, education, and children in general.

The Philosophy of “Atlas Shrugged”

The ideal “from each according to ability, to each according to need” continues to be held as an unquestionable good, despite repeated failures to make it a reality.  Even if this ideal is in fact impossible to attain (due to human nature, poor planning, or the corrupting influence of other cultures), we should still strive for it–or so the thinking goes.  But what is it that makes this ideal so desirable?  “From each according to ability, to each according to need” paints a picture of a world where everyone’s needs are met: a utopia.  But what if there were a different way to achieve that world–one which takes advantage of our basic human nature, rather than trying to “improve” it?  A world in which those who give the most to society receive, rather than sacrifice, the most in return?  The Objectivism of Ayn Rand’s Atlas Shrugged suggests an alternative path to utopia: it suggests that “from each according to ability, to each according to need” may not only be an impossible ideal, but also an immoral one–and that the creation and “selfish” exchange of value is not just the best way to get yourself ahead, it is ultimately the truest possible act of respect, charity and compassion a human being can perform.
