Wild safari mem usage

Dear Safari:

Do you really need a GIGABYTE of my memory? Why must you hurt me so?

Love,
Dave

My first barefoot run

I've decided that I want to run the half-marathon on May 1st.  I've also decided that I want to run it in my Vibram Five-Fingers shoes (http://www.wired.com/reviews/product/pr_vibram_fivefingers_kso).  I have a pair of the KSOs that I wore as much as I could when it was warm out.  Now that it's winter, I'm forced to run indoors at the gym.  Yesterday I took my first run in them.

They felt fantastic.  After a few minutes of running, I noticed I was taking shorter steps and landing on the ball of my foot, hardly using my heel at all.  This put alot more strain on my achilles and my calf, so after about a mile I decided to stop.  I'd been running a few times and got up to around 3 miles, but my lower legs were feeling much, much more strained than usual.

This morning I woke up to soreness in muscles I didn't know I had.  Tendons in my feet around my toes are sore, and my calves are burning.  It feels great, but it will take awhile to work up to running 13 miles in them.  I'll try to update more on these runs, but so far so good.  Next time I'll try to go 1.5-2 miles and see if I can do it.

The future of paper

Came across a decent analysis of the current state of ebooks, the problems they're trying to solve, and ultimately, the future of the paper medium.  As happens frequently, this discussion came from a comment on Hacker News:

It's pretty lengthy for a comment (and the author has a lot of respect for Apple, so he believes that's where the best solution will emerge).

My ebook experience

I'm going to begin chronicling my experience with my sony ebook reader.

I got my ereader two years ago and haven't used it as much as I could've. I recently charged it up and decided to try reading my next pursuit, "The Post-American World" by Fareed Zakaria (http://www.amazon.com/Post-American-World-Fareed-Zakaria/dp/039306235X).

So far, I've discovered that if you want to get books cheaply (read: free *cough*), you're searches are going to be hit or miss at best. Registering for a free account on Gigapedia is a must, and armed with your favorite BitTorrent search engine, you should be well on your way to finding what you'd like to read.

I haven't yet looked into interoperability between the Kindle and my ereader. Amazon is by far the easiest place to purchase cheap ebooks, so I need to do some research and figure this part out.

Anyway, I'm currently a few pages into my first book and so far I have no complaints. I had to convert what I found to epub or rtf in order to have it be flowable and readable, but that was no problem.

I also threw my lecture notes from my classes for future reference. Who knows if I'll use them.

Lastly: please comment if you own a reader and have had positive or negative experiences, tips, advice, etc. Thanks for reading!

Startup idea: subscription-based coffee shop

I have a music theory class every other day. Right next to this class is a local coffee shop where I would ideally like to pick up a coffee/tea/chai/whatever prior to class.

Paying $4 every other day for a drink before class is outside my poor-college-student budget. How could we fill this need? Could a subscription based coffeeshop model work?

This plan could be tiered depending on your planned intake. For me, I'd be paying around $30 / week for chai, so imagine if I could pay $30 / week for a drink a day. As a coffee shop owner, I could still maintain a fairly decent profit margin ($4.20 / day, with a cup of coffee costing less than a dollar). Or, perhaps something like $50-$60 / week for unlimited drinks. More complex plans can be created, allowing for different quotas and the like. The customer experience could be very, very good. Just distribute gift-card-like cards (possibly with advertising on the card for local businesses for some extra income), and whenever I want a cup of coffee/tea/whatever, just swipe it like a gift card and your drink is recorded. Overdrafts would probably be allowed, the same as running out of balance on a gift card.

Any thoughts?

EDIT: a friend also suggested adding food items to this, for example, paying $20 / week for lunch sandwiches and the like.  It might also be cool to mix and match subscription items, like 5 drink items and 5 lunch items per week.  Delivery could work, too.  Think Insomnia cookies for hot drinks and lunches.

The Road

Watching "The Road".

The whole atmosphere, the whole world, is dark.  The world has moved on, and there's nobody left.  A man and his boy must survive at all costs.  Time and again, their hopes are beat down by death, suicide, cannibalism, and the utter lack of humanity left in the world.

It makes me yearn for simplicity.  Their lives are miserable, daily fights.  But that yields them.  They have nothing left but who they are.  They have hope, and possibly the last compassion left on a roasted, dead Earth.

Our lives are cluttered with meaningless possessions, we surround ourselves with useless, unproductive and unsupportive time and resource sucking lives.  Too often we neglect to refine who we are and discover the lies beneath our covers.

We seek objects and things, when we should seek knowledge and diverse skills.  Life is not about collecting, it's about absorbing.  Needless to say, you can't absorb material possessions.

I shall try to remember what's truly important.

Barry Manilow...anteater?

Overheard today: "If there was ever someone who looked like an anteater, it's Barry Manilow."

Agree?  Disagree?

Is object oriented programming a waste of effort?

I've been studying for my software engineering final.  It's pretty well-established that writing code with the design and intent of reuse and modularity is a good thing.  Object-oriented programming has, as one of it's biggest patterns, polymorphism (specifically the idea that subclassing a class is sometimes a better choice than anything else).

But I came across a slide in my software engineering lecture that says the following: "Almost all classes have zero children.  Only a handful of classes will have more than five children."

There's some definite cognitive dissonance when one of the biggest parts of OOP encourages polymorphism from a design standpoint, and then we see that such a small amount of classes in the wild have children classes, and when a class IS subclassed, it only has around five of them.

Are we wasting our time by trying to teach this design?  Aren't we teaching this methodology and just not realizing that folks don't do it?  Or am I off my rocker?

Trusting your customers

I walked up to the counter at a store with some cheap items.  I was behind a man that was buying large quantities of stuff and the guy behind the counter was going to help him carry it to his car.  He noticed me and told me to just leave the money on the counter while he helped the other customer.  He trusted that I wouldn't just leave without paying.

This had a powerful effect.  It made me feel like not just another customer.  It changed the transaction from something cold and mechanical into a positive human interaction.  I wonder if this is possible to achieve on the web?

Sad state of grade/class software

I should be able to click something in my University class registration that will let me download an iCal or something importable into Google Calendar or Outlook.  This should contain my final exam schedule and all of my class lectures and any other pertinent information.

Why is this not possible?  Given a month, I feel that it's completely within my power to come up with a better system for class registration, class scheduling, room reservations, final exam scheduling, and a place to post grades for students.  Maybe I'm being arrogant but I'm pretty sure this problem isn't too difficult to solve.

Is cost the problem?  Would it cost a university too much money to migrate everything into this new system?  Perhaps.  But wouldn't it be worth the cost?  I get the feeling that if someone hacked together a solution that allowed all of this information to be displayed and interfaced with in an easy, pleasing, polished way, that would effectively show a university that the migration issue isn't a big deal.  

Conceivably it would just require time plus the cost of the software, which wouldn't have to be much lower than the current price they pay to be worth the switch.
