Slime Mold Grows Network Just Like Tokyo Rail System | Wired Science | Wired.com

3 Sep

When presented with oat flakes arranged in the pattern of Japanese cities around Tokyo, brainless, single-celled slime molds construct networks of nutrient-channeling tubes that are strikingly similar to the layout of the Japanese rail system, researchers from Japan and England report Jan. 22 in Science.

I’m a Guinness World Record holder!

19 Aug

I found out this week that I became a Guinness World Record holder by participating in Reddit’s 2011 Secret Santa match, which just earned the title of “Largest Online Secret Santa Game.”

Finally, something to put on my resume next to “TIME Person of the Year 2006.”

Census 2010 Summary File Summary: There are fewer

28 Jul

I’ve been doing a lot of work lately with various Census products. Mostly recently, I’ve been trying to pull together some data to visualize trends in  the number of bike commuters in Oakland.  This data is readily available in Summary File 3 (SF-3)  for the 2000 Census, and you can also find it in the American Community Survey (ACS) files.

My understanding was that the ACS files were kind of a stop-gap measure: they provided more current information than the decennial census, but were lass accurate. I thought for accuracy’s sake, I should use the SF-3 file information from both 2000 and 2010, in addition to the ACS data. Since I couldn’t find the SF-3 data for 2010 on American FactFinder, I figured it must just not be released yet, so I waited.

Today I discovered it doesn’t matter how long I wait — there won’t be an SF-3:

So, although many data users were expecting the full suite of Census indicators they had in the 2000 Summary File 3, the Census has changed its delivery method and methodology, and it is now distributing many of those through the ACS. The good news is that the ACS is updated annually, instead of decennially, and so estimates for household income, poverty and the like will be refreshed every year.

More Bus Rapid Transit for Oakland

21 Jul

Earlier this week Oakland City Council unanimously approved plans for a Bus Rapid Transit line along International Boulevard. The buses will have a dedicated center lane, so service can be faster and more dependable. Plus more crosswalks, bulb-outs and bike lanes — what’s not to love?

Assessing the economic viability of a potential BRT line on International was part of the larger Complete Streets internship project that got me involved with transportation planning about a year ago now, so this news is particularly exciting.

Thinking about “A Geography Lesson for the Tea Party”

3 Jul

The Washington Monthly – The Magazine – A Geography Lesson for the Tea Party.

A friend of mine sent me this article a while back, but I am just getting around to reading it now. I really enjoy the way the author makes America sound like some kind of high fantasy land created by the likes of George R. R. Martin with different cultural bulwarks and aristocratic mechanitions. Like with those fantasy books though, my somewhat shaky geographic sense leaves me flipping to the map in the map in the front a little too often.

I dislike, however, the author’s insistence on citing election results (particularly presidential ones) as evidence of an ideological schism. Ever since reading Fiorina’s Culture War, I have this little voice in the back of my head asking if it is really more valid to see that red/blue map as polarization of the populace rather than apathy or polarization of the elite.

Either way, I’d like to read the author’s book, even if I would enjoy it more as a work of fiction.

What’s that little fancy ‘s’ that shows up when you talk about laws?

22 Jun

I’ve been seeing little § marks crop up in the things I read for years now. It wasn’t until today that I learned it is called a “section sign,” and can be created with a simple Windows Alt code: [Alt] + [2] [1]. I don’t have to copy and paste from whatever I’m reading any more!

Here’s a neat little blog about the origins of various typographic marks, including the section sign:

Staying academically sharp over the summer (and the rest of your life)

4 Jun

It’s hard to believe that my formal educational career is over, or at least over for now. I have my Master’s degree. No longer will I have professors, syllabuses,  and reading lists carefully curated to keep me thinking big thoughts. For ow on, my education is a quite a bit more up to me.

Luckily, in a world that contains Khan Academy, open course material from all kinds of major universities, and  all the TED talks you can handle, staying academically engaged even outside the actual academy is easier than ever. My friend and colleague Lili is blogging over at GradGuru, and recently asked “What are you doing this summer?“. My main goal this summer is to start learning how to code with CodeAcademy. How about you?
