I've recently gone through one of the hardest experiences of my life.
During the month of December, I made a new friend (a girl who worked at the University) and enjoyed the brief time I was able to spend with her. The getting-to-know-you phase was cut somewhat short by the holidays (I went home for a few weeks), but we still kept in contact. On December 30th, I flew back into town to plan a New Year's Eve party, and picked her up to help buy decorations. About 5 minutes after I had picked her up, I made the turn into my apartment—the same left-handed turn I'd made hundreds of times in a year and a half of living there—and was broadsided by an oncoming car. I was knocked unconscious so there's a good chunk of my memory that's rather blurry (and I remember none of the incident or the supposed other car), but after a few CAT scans and other procedures, I was released, completely fine.
She never made it out of her coma.
The ten days between when the accident happened and when she finally passed were some of the hardest days of my life: wrestling with God, with my emotions, trying to accept what happened. And the days and weeks that have followed have not been any easier. Since that time, I've gone through a complete gamut of emotions: intense guilt followed by sweet peace; sadness and fear that things will never be the same, followed by an optimistic hope and a knowledge that they would...followed by the confused, gradual, heavy settling that she was permanently gone and I was powerless to do anything about it; concern that I had forgotten her and moved on too quickly followed by intense, violent sobbing...
I've also learned a lot about comfort in grief. I've learned that the worst (and yet most common) thing one can ask is "How are you doing?" (Are they using the phrase in its trite, meaningless greeting sense, or do they know what happened—and are they prepared for the floodgates that might be opened in response?)
But most of all, I struggle with the "What can I do for you?" question—which is traditionally followed by "No really, what can I do for you?" and almost always wrapped up with "Well remember that if you need anything, I'm just a phone call away." As if repetition and emphasis makes up for the burden they've just (knowingly or otherwise) placed on my already-weary shoulders, the burden of making them—the non-grieving, nonetheless—feel better by offering them control in a situation that for me has been spinning violently out of control for days and weeks and now months... I've since quit telling them, "Well for starters, you can never ask me that ever again," and have instead opted to just smile and thank them for their concern. Sometimes, the simple repeated song is all that humans or birds know how to sing.
In stark contrast, the most meaningful expressions since that day have been in the form of gifts. Gifts I neither asked for nor expected, but sent me to tears nonetheless—tears of appreciation and gratitude and friendship and love. One such gift was the remote to our apartment complex gate, so I could take the back entrance instead of revisiting that same left-hand turn day after day, driving over the fluorescent-green painted lines in the street that shouted to all passers-by "something terrible happened here."
The other gift that meant the world to me was a pair of pants. Someone should have told me when I got on the plane that cold December morning to put on a pair of ragged jeans and a sweatshirt I didn't care about. When they pull you from your totalled vehicle, they don't ask you nicely to lift up your arms as they gently take off your jacket. They don't even spend the time to unbutton your shirt or unzip your pants. Instead, they take scissors (or a knife or bolt cutters or a blow torch or whatever they have handy, I guess) to the lot of it, giving it back to you in a hospital carryout bag like a prize from Dave & Busters. No, they really should have told me not to wear my favorite outfit, to keep my faux leather jacket I still haven't replaced safely hung in the closet, to keep my brand new pair of Bonobos safely unpacked, and to save my favorite flannel shirt for a different chilly Texas day. So when the pants came in the mail (from one of my very best of friends who, despite her attempts at remaining anonymous, left her billing address on the packing slip), I was once again reduced to tears. But this time, they were welcome tears, appreciative tears, and--most important--tears I could experience on my own, in the comfort and privacy of my own car, and at the rate I wanted or did not want.
Maybe this is the way all grief is: the disgust with trivial "checkins," the appreciation of gifts. Or maybe I'm different. In conclusion? Save your favorite outfit for a day when you'll decidedly maintain a comfortable distance from ambulances and paramedics with blow torches. And buy a friend a pair of blue jeans.

Musical Turing Test
I currently TA for an undergraduate Issues in Computer Science class, and during one of the lectures, the professor talked about a computer's ability to create art and music—which, one might suppose, are very "human" skills. Can a computer compose music? Sure...but it won't sound quite right. Right? In class, the professor tried this with two composers: Bach and Joplin. For each of these composers, she had a computer program generate ("compose") a musical piece after it had identified patterns ("learned") from a lot of music from that composer. She then recorded a pianist playing the computer-composed piece, so a piece generated by a Bach-learned program would sound a little something like Bach, and a Joplin-learned one would sound quite a bit like your typical Joplin rag.
I won't bore you with any more details (there are a few more at the actual test—you should take it, it only takes 7 minutes tops), but the results were interesting. During class, the teacher juxtaposed each computer-composed piece with an actual human composed piece, and then asked the students to pick the real piece. The performance was terrible. It was clear these students couldn't tell the difference between a great like Bach and a computer imitation of Bach. But then I began to wonder: as I took the test, I was able to pick out each of the real compositions. Was this because of my musical background? I decided to give the same test to a larger audience, this time recording their self-reported musical experience.
If you're not interested in the individual results and discussion, the takeaway is that, even among self-reported musicians, only just over 40% of the individuals were able to correctly identify the human composer. Yes. Only 40%. In other words, more often than not, humans think computers are more "human" composers than Bach or Chopin or Joplin. This is a terrible result! (There's a pretty good description why this is bad in this RadioLab episode, at about 16:26.) I'll try and go into it more in the Analysis section below.
Population Distribution
For those of you interested in the questions and population distribution, I've been updating the values here. For your information, the quiz consisted of 6 questions: three background, and three with the paired audio samples. For the first three questions, here are the number of respondents (total of 247) in each category:

For your information, the quiz consisted of 6 questions: three background, and three with the paired audio samples. For the first three questions, here are the number of respondents (total of 247) in each category:
- What is your major field of work? The responses were free-form and varied from math to computers to culinary arts to music to motorcycle repair. I haven't looked at any of these responses past collecting answers.
- Do you play any instruments? This was multiple choice, divided into 4 categories of increasing "musicality." Here are the number of respondents that self-selected each category:
- No: 28
- Yes, but I've picked it up on my own without lessons: 27
- Yes, and I've had official lessons for at least one year: 131
- Yes, I would consider myself a professional musician: 61
- What is your technical musical background? This was also multiple choice with 4 categories, and had the following number of respondents:
- None: 38
- I know some musical theory, but I've picked it up on my own: 42
- I've taken a class or lessons in musical theory: 124
- I'm a professional musician or majored in music theory: 43
Categorical Results by Response
And here are the responses, separated into response for each category
And here are the responses, separated into response for each category
Second question, accuracy by response:
1 - 27.4%
2 - 40.7%
3 - 42.0%
4 - 50.3%
Third question, accuracy by response:
1 - 32.5%
2 - 42.9%
3 - 40.9%
4 - 54.3%
Average total accuracy:
42.2%
The overall accuracy for all three composers was 42.2%. In other words, only 42 out of 100 times were people able to correctly identify who the human composer was. There probably aren't quite enough samples to show statistical significance, and the survey process wasn't exactly accurate (I didn't prevent anyone from cheating—they could take the survey as many times as they wanted), but there does seem to be a general trend that with musical experience, the accuracy increases.
This is what I expected.
Almost.
On closer inspection, this all is actually quite disconcerting. With the sole exception of those who are professional musicians, humans think that the computer composer actually sounds more human. How could this be possible? Well, I can think of a couple of possibilities.
First, it's possible that there was a hidden variable we weren't controlling for. I had my roommate take the quiz first, and he got them all right. I asked him how he did it, and his response was that he just picked the better recording each time. Oops. When I designed the quiz, I already had the mp3 files for the computer composers, but I was lazy with the real compositions and just ripped the music off YouTube clips. I went back and actually purchased the music off iTunes so they would sound more similar. When I sent the survey out to a larger audience, there were more issues. Turns out iTunes adds album artwork, which was displayed in some browsers when they played the music. Oops again. This was a little harder, but with some online conversion and VLC magic, I finally cleared them all of their extraneous information. Perhaps there is something more I'm not controlling for—if this were real science, I'd want to have the same performer play each piece and be recorded with the same device. Good thing this isn't real science, right?
But there's another possibility that seems more likely. When the computer "composed" a piece by Bach, she wanted it to sound as much like Bach as she could, so she consciously added bits and pieces of actual songs. But when Bach really wrote his pieces, his goal was to create something new and fresh, something that didn't sound like anything he'd written before. Something that people would clearly identify as Bach--or would at least recognize it when they heard it before. All of his similarities to previous works were subconscious, influences from his schooling, the music he enjoyed listening to, even some of the music he previously composed.
Conclusion
With high statistical confidence, humans think that a computer who is trying to imitate a Bach piece actually sounds more like Bach than the composer himself. Maybe this is bad (computers will eventually replace composers and artists and singers and all other "human" fields), but maybe, instead, this identifies an aspect of talented human creators: the ability to create something truly unique.
Note1: As people take this test, I'll update the results on this page. Hopefully I replace them all so it makes sense. Also, if you want some more statistics, I can try and get them to you—or I could probably give you the data myself, it's pretty well-anonymized.
Note 2: The first numbers were published on 23 Nov 2013 with 65 respondents and 42.6% accuracy. The results were updated on 26 Nov 2013 with 99 respondents and 40.7% accuracy. They were updated again on 11 Dec 2013 with 201 respondents and 42.8% accuracy. They were updated on 12 Sep 2014 with 247 respondents and 42.2% accuracy.

Back it up
My hard drive just crashed, completely unexpectedly. I have a high-end MacBook Pro that I only bought in 2011, so it was well under the typical 5-year life of most spinning drives. I learned two lessons from this experience:
- Get the Apple Care. If you're buying Apple, it's one of the best add-on purchases you'll make. It gives you three years of protection (most companies only give you two), and it's only a fraction of the cost of your entire machine. The amount you spend will definitely be justified by your peace of mind. Apple replaced everything for free--and did it all over the weekend (I went in on Saturday and was out by Monday. The lag was because I had customized hardware). Very fast and efficient.
- Back up your devices. While waiting in line to pick up my laptop, I stood behind an older gentleman who was obviously distraught after losing data on his phone--probably in the form of non-replaceable pictures of his grandkids. Unfortunately, there isn't much you can do after the fact, so prevention is the only way to go. Get a large external drive, something like the 3 TB Seagate drive I have (on sale, it's just over $100--definitely worth the hours of time you'd spend rewriting all your papers). If it's this big, you can also use it to store any pictures and music and movies that don't fit on your machine. Make sure you set it up to remind you to back it up every 10 days or so, or you'll forget and will have wasted the $100.
Do it. You won't regret it.
And to help you remember, I've included this wonderful song:

Le Scaphandre et le Papillon
I watched a movie the other night, Le Scaphandre et le Papillon. It's about Jean-Dominique Bauby, journalist and editor-in-chief of Elle magazine. He suffered a massive stroke that left him with "locked-in syndrome:" he could think, hear, and see, but couldn't move anything but his left eye. Ten days after he finished his memoir (after which the movie was named), he passed away.A few weeks ago, my right arm started to ache. At first I thought it was carpal tunnel, but the symptoms pointed more toward tendonitis. I looked around on Google hoping for an easy cure (something like, "do arm yoga every morning for 15 minutes") but was sorely disappointed when all sources agreed that "the first stage toward recovery" was to "stop the repetitive actions that caused the tendonitis for at least 3 months." How does a computer science PhD student doing an internship at Google stop typing?
Although it's nowhere near the life-altering condition of Jean-Do, I wondered what it would be like if suddenly my life were completely and irreversibly turned around. Like the construction worker who breaks his back in his late 40s, or the medical doctor who goes blind. What if I could no longer type? Or even worse--what if I could type, but I'd be miserable the rest of my life unless I chose not to?
Maybe I'll pull an Angelina Jolie an preemptively become a genetic counselor.

I got sunshine in a bag
I have a computer science department mailbox I don't usually check, partially because it's not very convenient, but mostly because it usually just has junk from "Friends of CS" (tech companies pay money to the department for recruiting purposes). Today I had a couple pieces of mail that were surely, from the looks of it, sent by Friends of CS. One in particular caught my eye since it had what appeared to be a printing error on the address. I figured it was just a form-letter that did a really good job of imitating handwriting (I'm always impressed with mass mailings that do a good job of this).
I opened the envelope and saw the following:
This was probably the best way to start an otherwise rough-starting week. I don't know how long ago this letter was sent (I was the TA for this student last fall), and I'm super glad the department hadn't thrown it away (although they could have tossed the announcement about the pizza party last month). But mostly, I'm glad this student (I removed his name so it would be anonymous) took the time to express his appreciation. It was a small thing, but it made a big difference.
Thanks, [name removed for the sake of privacy]!

My first thought was that someone wanted my money. No thank you. On the way to the trash, I flipped it up to read the inside.
