Factual Google

Google is building fact mining into the search engine. Coming across a little article over at The Best Article Every Day, I got wind that Google Spreadsheets can do lookup of certain statistical and financial information. You can have formulas that include things like the latest Microsoft stock quote or the boiling point of sodium. This seemed interesting, so I played with it a bit, but changing the formula quickly to play with it was awkward. "Can I just Google this stuff," I thought? Yes. Read on for my findings.

The documentation for the Spreadsheet function, GoogleLookup, talks about entities and attributes. "Pluto" is an entity and "mass" is an attribute. As it turns out, you can just search for "mass of Pluto" or "birth rate in Canada" and are presented with a new type of search result.

We can see that Google seems to be pulling facts from the websites they index. They are structuring the information into subjects and properties about them. The feature has some large holes of missing functionality. "boiling point of sodium" gives a fact, but the system fails to parse any of the hits for "boiling point of mercury". The information we can get seems a little hit and miss. The community needs to put effort to document all of the entities and attributes.

One interesting result is searching for "mass of Pluto" doesn't just give us a fact result, but what appears to be a Google calculator result. This means they are recognizing the mass in both value and units. We can even use "mass of Pluto" in any calculation we would give to Google calculator.

As the shift is made from taking finding relevant documents to just giving us the information directly, we might wonder what the future of the search engine is. I expect we'll see someone in the next year bring Google to court for yet another lawsuite about what they can or cannot scrape from their website. When you have a nice site with good information, and Google just gives the users the data, you probably worry about the affect on your traffic. If it does affect traffic, then will the sites Google is grabbing the information from even remain active? Where will they get facts from when their facts pulling eliminates their sources?

Pretty interesting. I think I'll just stick with typing things in the regular Google web search.

The Insidiousness of The Slow Solution

In software development, slow solutions can be worse than no progress at all. I'll even say its usually worse and if you find yourself making slow progress on a problem, consider stopping while you're a head.

Its easy to see why fast progress is better: either you solve the problem or you prove a proposed solution wrong and find a better one. Even a total standstill in pushing forward on a task or a bug or a request can force you to seek out new information or a second opinion.

Slow solutions, on the other hand, is kind of sneaky. Its insidious. Slow solution is related the Sunk Cost Fallacy, but maybe worse. Slow solutions have you constantly dripping more of your time, energy, and hope into a path that's still unproven, constantly digging a hole. Slow solutions are deceptive, because they still do offer real progress. It is hard to justify abandoning it or trying another route, because it is "working", technically.

We tend to romanticize the late night hacking…

Finding "One Game A Month"

I was really excited about the One Game A Month challenge as soon as I heard about it.
For about two years I've struggled in fits and starts to make my way into game development. This hasn't been productive in any of the ways I hoped when I started. Its really difficult to be fairly experienced as a developer, which I believe I am in my day job as a web developer, while struggling really hard at an area in which your experience just doesn't exist.
Its like being a pilot who doesn't know how to drive.

But this challenge provided a new breath to this little hobby of mine. It gave me a scaffolding to experiment, to learn, to reflect on finished projects. I had spent far too much time on game projects that stretched on far past their exciting phases, bogged down by bad decisions and regret.
And it has worked.
I have a lot to learn. I have a lot of experience to gain through trial and error and mistake and discovery. I have a lot of fun to be had making more small games t…

On Pruning Your Passions

We live in a hobby-rich world. There is no shortage of pastimes to grow a passion for. There is a shortage of one thing: time to indulge those passions. If you're someone who pours your heart into that one thing that makes your life worthwhile, that's a great deal. But, what if you've got no shortage of interests that draw your attention and you realize you will never have the time for all of them?

If I look at all the things I'd love to do with my life as a rose bush I'm tending, I realize that careful pruning is essential for the best outcome. This is a hard lesson to learn, because it can mean cutting beautiful flowers and watching the petals fall to the ground to wither. It has to be done.

I have a full time job that takes a lot of my mental energy. I have a wife and a son and family time is very important in my house. I try to read more, and I want to keep up with new developments in my career, and I'm trying to make time for simple, intentional relaxing t…
