Always carry a USB flash drive with you; you never know when you may need it. They are incredibly cheap and small now; they can easily fit in your wallet (pick the micro version that’s barely bigger than a quarter since you don’t care about speed, like this one).

Life Hack #10: Carry a USB Drive with you
Friday, August 21st, 2009Bananas
Friday, August 21st, 2009I don’t like bananas. To be clear, this one is more of a personal rant than anything that’s bad with mankind, but the fact that everyone else seems to love bananas (and I mean love with a capital “L”) baffles me.
Bananas are mushy, don’t stand the test of time very well (black bananas… Yuck!), and are usually messy to your hands (you have to touch the inside of the banana when you peel it). They are not really all that tasty and have a high caloric content. Finally, having too many makes you feel nauseous.
But again, all this would be fine if not for the fact that men and women of the Earth have chosen to make a banana the representative fruit of the planet. If there was ony one fruit to save, it would no doubt be a banana. And it affects me- 90% of smoothies include bananas in the flavors; a disproportionate number of desserts are made with bananas; there is even a special ice cream sundae dedicated to the banana (banana split). Why not apricots, which taste so much better in desserts? Why not strawberries which are obviously more aesthetically pleasing (being so prominently featured in works of art; has anyone ever heard of Banana Fields?)? Why not black currants which are the underdog of fruit yet to anyone who has tasted them they taste surprisingly well-balanced and, well, just are sexy?
It’s not fair.
“Like”
Thursday, August 20th, 2009I really dislike this word. I know I shouldn’t- I know that every language needs fillers, like “yyy” in many Slavic languages and “ehm” in English, but to use an actual word as one is too much.
The reason it’s too much is precisely because it’s an acutual word- it’s confusing (some “likes” should be transcribed, some should not), it deters people from actually using it, it makes speech less comprehensive because our brains have to work extra hard (even if by now we’ve all gotten used to such a terrible practice).
It’s also bad because “like” can and should be used as a filler in some circumstances; it’s appropriate when we’re describing something with the use of a hyperbolae (“He was, like, eleven feet tall”). But since people abuse this word, it’s potency (and thus the potency of the hyperbolae) decreases.
So join me in purifying your everyday speech and getting rid of “like”.
Slippery When Wet
Wednesday, August 19th, 2009I consider this phrase to be a representative phrase for all disclaimers which are absolutely commonsensical but exist to clear companies from any liability. “Processed in a factory that also processes nuts” that I mentioned some time ago is another such example. The problem with such phrases is that it’s now impossible to separate what I really need to worry about from what is just some legal jargon. For example, is it really medically required to take altitude sickness pills when you climb a high peak or not? What about chlorine in te drinking water? Ideally I’d like to know more about the risk groups (e.g. Dumb people should note that wet floors are slippery–well, that’s a joke and a load of sarcasm, but you get the idea).
From the Archives: Reflections of a 24-year old
Tuesday, August 18th, 2009When I turned 24, I wrote a pretty lengthy piece with my reflections on life. It was, as far as I can tell, the first such attempt. I’m putting it here for posterity.
Let me tell you a little bit about myself. I have not once in my life stepped back to reflect on my life, values, and relationships. Until tonight. It’s strange that it took me 24 years to figure it out but the mind, which one usually employs to do hard tasks whose execution is in some way related to your paycheck, does crazy things when one lets it just roam freely.
24 years old. I don’t feel old. I feel creative, full of potential (some of it untapped even by the Man himself), I feel refreshed. I finally “got it”. The little scraps have been flying through my mind since forever, although in the past few months they have intensified. Now it all makes sense — and while it would be a cliche to try to encapsulate it in two words, I’d give it a try: Live free.
Live. At the end of the day, that’s all you have. Your life. It’s your own little movie, with many actors (one of them you), a script (written by you), a director (you), even the stunts (yup, it’s all you). There is nothing in this world you can take better control of than your life. Many people forget about it — they allow their life to control them; they are defined by the routines they do; they convert the simple active “Live” into a passive “Let your life by lived by you”. This seems awkward, doesn’t it (it’s gramatically correct, of course). But more than that, it literally suggests that you should allow this ephemeral, esoteric thing (“life”) take the lead (“Let your life”, as in “Allow your life”), putting “you” conveniently at the very end of the sentence. Don’t do that. Live. Active. Don’t be a spectator in your little movie. Be the cast! Don’t let your life be controlled by the collective, the “Civilization” (more about that later); don’t be a puppet whose strings are pulled by the shared conscious of mankind. Be an individual (a brilliant scene from Life of Brian comes to mind).
You heard it right — “Live” is an imperative. It’s something you’re supposed to do (you may not think of it this way, but the way I see it, the originator of this imperative is “life” itself, which adds the whole thing its devilish meta twist and I love meta); it’s a rule but shouldn’t be seen as one — rather, it should be seen as a subordinate phrase in a conditional — sorry for my linguistic snobbism — “If you want to [X], Live freely”, where [X] is pick-your-poison. It’s whatever dominates your utility function (so by definition, the premise is true: you DO want to [X]). This framework is also helpful because it shows you a very important principle — that the best things in life don’t come pre-packaged — whatever wisdom you get, you have to synthesize it yourself, draw the right conclusions, flavor it with the context of your life. So “Live” is not equivalent to hedonism. It’s also not equivalent to total altruism. It demands for you to define your utility function — “what makes me happy? / what makes me feel good? / or from really first principles: what do I prefer to do over anything else (or a pareto optimal frontier thereof)?” — and steer your life so that your utility function is maximized.
“Free” not in the meaning of “freedom” or “liberty” as we have so literally started to take those terms in the past few decades especially in the U.S., but in the meaning of “unconstrained”. Don’t let obstacles slow you down. You’re racing 90mph down a curvy road (say, one of the many roads in Northern Fairfield County). If you see an obstacle, you don’t stop or swerve. That could end up badly for you. You go right through the obstacle. Minor bruise for your car, and a decision that could have just saved your life. What are those obstacles? They take many forms: restraints we put on ourselves for no apparent reason (“I’m not going to understand this book, so I won’t bother; I should just watch the movie instead”); “convention” and “norm” (which those two words, incidentally, are my “bad idea bears” for the day) which keeps us from being different, unique, from making an impact (ironically, mathematically “norm” is by definition a transformation that maps different instances of some entity into one instance, and is often defined to help us tame entities into something we know and expect (hence no impact) — so by definition “norm” is an antonym to “uniqueness”); and finally, and most importantly, problems in our lives, the little ones, and the big ones. Most people let those problems bury them; they are like a smog that prevents you from seeing ahead, from seeing your life and the paths it could take; that prevents you from having a vision (literally and metaphorically!) of your life; that prevents you from being great. Don’t be one of those people. Solve your problems.
Paul Graham (yeah Kemp/Alex/Will), one of the wittier computer science writers alive, said once “I don’t hate bugs [in my code]. I love bugs! Because there I am, against the bug, and the bug knows it’s just a matter of time before I kill it. miau.” This holds true for problems — approach them systematically (one thing that problems love is an unsystematized approach — like not having a plan for how to solve them, or solving too many at once, or solving each problem as its own “instance” rather than seeing patterns and killing the problems even before they are born!). List all your problems (that’s the OCD part of the process). All of them. It might be a long list. Don’t be embarrassed — only you and Microsoft Word (or vim if you swing that way) will know. Then, for each problem, figure out the root cause (that’s the “Sherlock Holmes” or “House, MD” part of the process–reverse engineering things). This is where it gets tricky — because some of the problems you thought you just listed are actually diagnoses, so you’ll have to go through the list again. It will most definitely be a long and arduous process (but then, just do a little each time — surprisingly, not that many new problems enter our lives every day!). Once you do that, figure out (that’s the creative part, the “van Gogh”) the solution. That’ll already take you further than most of us have ever been. Then define a gameplan for those solutions (the “coach” part) — what do you plan to do first, by when, etc. Finally, execute (the Pierrepoint part — by the way, it looks like a good movie. By the way to that aside, got lost in the tangents? It’s a stack; easy to get back on track). A mistake I have been making for many years was manyfold: not listing all problems and conflating them with root causes, and not executing on the gameplan. You need those two extremes to work particularly well — they are your interface to the outside world.
(curiously, the settings of my mail window made it so that in the paragraph above the longer words “understand”, “incidentally”, “mathematically”, “defined”, “uniqueness”) all line up in a visually-pleasing diagonal (the “high density” letters such as m, e, a, h make this diagonal apparent). See if you can get that with your mail program — try out some window widths. I’m not going to tell you what my width is — and yes Will, although you could actually compute it given the information I provided — the average number of characters by which these five words I mention are apart — I encourage you to experiment. Perhaps you’ll see patterns that I failed to see. Rather than showing you this one pattern, I would like to teach you how to see patterns.
Speaking of teaching. Calling it “important” would be a huge understatement. I think the ability to teach defines mankind. Whatever definition you take for mankind (not related to the species but to the phenomenon), it somehow rests on the notion of civilization (do that exercise! — try defining “mankind” or “intelligence”). Civilization is this strange thing — it’s intangible yet it assumes the existence of so many tangible objects; you think of the “Roman civilization”, you see the Colosseum, the Legions, Asterix, the lazy fat guy resting on some sort of hammock and eating grapes — all tangibles! It’s man-made (does not occur in nature), it transcends man (a man dies, civilization stays), it’s — I’d claim — the closest one can get to calling something “man’s soul” — the intangible shared information that’s part of the collective), it’s made possible because of the institutional memory, which one man passed to another by teaching.
(Aside: if only humans could all communicate through the mind — what I saw in my mind as a simple equivalence took me an entire paragraph to write up).
I’ve taught some classes in college, I’ve taught the new hires at work, I’ve taught my brother how to take square roots (no calculator!), I’ve taught my parents that family, no matter what the short-term bumps or the long-term distance might tell you, is incredibly important in one’s life, it’s embedded in one’s conscious. These are all instances of the same principle — “sharing your passion to know/feel/think/do with others”. Everyone can be a teacher in this framework. I encourage you all to share your passion. Whatever it is.
Live free. This sounds simple but in fact it’s so generic it’s not very useful (remember: pre-packaged stuff) unless you internalize it. And this is the thing: you can read about it, you can be told this same thing over and over again, you can be forced to memorize the definitions and the corollaries of this, but you won’t understand it, you won’t “get it” unless you reflect on this phrase, let it assemble with your mental framework while it’s fresh, and let it purge your framework of weed (Ideally everyone’s mental framework should be one principle, the Master principle, from which everything else is derived; but as humans we like to create “caches” or “short-circuits” so we don’t have to re-derive all the time. The problem is that when we rely too much on the caches, the cache becomes a part of your framework in fact obfuscating the Master principle. The great thing about the framework, unlike Will’s code, is that it can be refactored (cleaned up, rearranged) really easily. You just need to think about it; reflect.
So as you reflect on the gist of this email (again, this is meant to transfer my passion about this, not the individual facts or inane adages I may have inadvertently constructed), the phrase “Live free” will enter your framework, but as it passes through the plumbing, it (like a virus — a “good” virus) has the ability to destroy those stale caches and simplify your framework.
As you see, this email, too, is very strange coming from me. Perhaps tomorrow I’ll be just my former self. But perhaps, all the thoughts that races in my mind tonight made me realize the value of reflecting. You should all do it sometime. Your brain deserves it.
What’s this mystical “framework” that I so eagerly refer to in this email? A framework is a set of principles that’s logically sounds (but not necessarily complete), possibly adorned by those “shortcuts”, where for example, we substitute an example for a proof that one principle follows another (principle: humans are all capable of accepting teachings and incorporating them into their framework (sorry, self-referential again. “Learning” would just unnecessarily litter our space with one more word that we have to define); derived principle: experiences in life can provide such teachings. It’s not too easy to derive it from the former (something like “we accept teachings” => “teachings must be facilitated by a teacher”; “the teacher must share with us more than what we contain in our framework” (otherwise it’s a vacuous case) AND “we experience signals from the outside world” AND “some experiences are not part of our framework” (which is hard to prove) => “there exist experiences that are teachers so we can learn from them”. See — that was hard. So we substitute in an example “I touched a hot stove when I was a child and got burned: I learned not to touch hot things”) [yeah I got lost in the parentheses, too]. If not an example, we substitute in a model (for example, we understand gravity through a proxy of the infamous F=mg. But do we really understand gravity or just the mathematical implications of the model?). While the example/model is a good shortcut from the whole proof, if used too much, it will replace the proof entirely and then, since in examples you don’t need the statement of either the derived or the higher-level principle, you forget what those principles were. You can imagine this process cluttering your framework all over — it’s going to be impossible for you to get to the highest level principle (there’s always one — semantically it’s equivalent to saying “stick to the set of axioms you accept as true” — because you can definitionally derive all other principles from it).
So this is why reflecting allows your framework to clean itself up. Forget the examples, forget the specifics. Forget the F=mg formula/model, forget the falling apple example. Think in terms of high level principles: mass attracts mass. [Sorry for all the physics, guys].
Why does your framework need to be clean? Because if it’s clean, you have direct access to all the principles (through the proofs), and thus to the highest level principle. If you do, and if you learn to apply the principles to life, you will LIVE your life FREE.
If you’ve made it all the way to here… some lighter stuff:
Claim 1. This is not a moral reasoning paper or an introduction to expository writing. In fact my paper for the latter in college was an analysis of Dark City (one of the greatest sci-fi movies of all time) submitted as a web page.
Corollary. Most of what you just read could be crap — it could be fantasy, hallucinations, rambling. Please approach it critically — ask questions if you’re interested, argue if you disagree, present counterexamples. (Although hopefully by now the “good” virus I just planted in your head with this email worked its way into your framework and removed some of that old weed…)
Proposition 1. I propose as means of assessing the amount of reflection one has done to count the occurrences of semicolons in some writing that is inspired by said reflection.
Corollary. This write-up has 17 semicolons; oh wait, now it’s 18.
Completely subjective opinion. 18 semicolon-worth — that’s a fair bit of reflection!
Where do all these t-shirts go?
Monday, August 17th, 2009In order to gain an edge over competition at Superbowl finals, t-shirt companies make t-shirts with both winning teams on them. When the winner is announced, the company ends up selling the half of their stock that had the right team. I’ve thought of this as a great example of good pricing analysis (the value of being the first one out with a product outweighs the cost of all these useless t-shirts) but not a particularly efficient thing to do. However, a friend recenty revealed one mystery to me: he was on a trip to Peru and saw all those people wearing the t-shirts with the other team supposedly the winning one. So that’s where all these t-shirts go!
Life Hack #9: Outlet adapters
Monday, August 17th, 2009Most electronics you own that you will want to use abroad does not need a transformer (big box with electronics in it). A simple plug adapter will do. You may want to get a universal one that converts any type of plug into any other, but I found it more efficient to use a semi-universal (convert from U.S. into any other, because that’s what you need anyway) or straight up specific one (these are tiny).
Life Hack #8: Charging your stuff at airports
Sunday, August 16th, 2009Most airports have outlets hidden around the walls. Try some spots near vending machines or near stores. I’ve never been told to go away so I think at least for now doing this is fair game.
If you want to use your laptop while you charge it, to save power, turn off what you don’t need- Bluetooth, wifi, turn the screen to lowest brightness setting. I found the combination of these three things to reduce power consumption by 70% (and thus speed up the charging). Do the same on the airplane.
Dannon and other brand renaming
Saturday, August 15th, 2009A French dairy conglomerate Danone known for making yoghurts is quite popular, both in Europe and in the United States. In the latter, however, the company renamed itself to “Dannon”, supposedly to make it easier to come up with the proper pronunciation. I find this ridiculous–for one, I believe it’s at some level insulting to the American’s intelligence. As much as we all like to make fun of the common American’s ignorance in a number of fields, particularly geography, I think things such as the pronunciation of company names are fair game to the regular consumer. Such inconsistency simply looks bizzare (I would like to know which consulting company “suggested” that this was a good idea).
Similarly, identical products have different names. Take “Bounty” for example (here a flat Almond Joy?). Again, I’m sure such rebranding makes a lot of sense from some point of view, but that point of view is not the most intuitive one, at least to me.
Crying babies
Friday, August 14th, 2009Many people are bound to disagree with me, but (at least until I have a child myself) I will stand my ground. Crying babies are really annoying and in my view being in a possession of one obligates you to follow some guidelines. For one, please minimize trips by air. It seems that an unofficial “standard” was developed where babies crying their lungs out is fair game; in fact parents seem to feel no remorse or willingness to reduce the annoyance their one child brings to hundreds of passengers. Whatever happened to parents being conscientious (or at least socially conscious) and leaving their children with the nanny or a member ofthe family? If such a thing is impossible (note that it won’t necessarily be free- there is a cost associated with having a child!), for God’s sake, feel the remorse! Minimize the crying. Pick a time when the baby is least likely to cry.
As an aside, I wondered why people with babies aren’t all placed in one, cornered off section of the plane. Just like the smokers are in smoking areas at airports–after all, smoking is damaging to others just like having a crying baby is.
As another aside (and I’m unwisely entering the realm of unreasonability) I’m curious why no progress has been made on some kind of medicine that puts babies to sleep for the duration of the flight. I’m sure it’s nontrivial given that we don’t really want to cause any damage to the babies’ health (and such a thing is very difficult to prove or disprove) but I’m surprised that nobody has thought about it.
