Internet Radio
I’ve been listening to a lot of internet radio recently, and it has me all
excited about music. I love that I can hear a song on an internet radio
station, get the name of the song and the artist off of iTunes, and then
immediately look the artist up on the internet. More often than not, their
music is on YouTube. In honour of this, I’ve created a new category in my
blog- the music category. I’ll use this category to post about songs and
artists I encounter on internet radio. Latest find: A track billed as
‘Rumpelstiltskin’ by Alan Hawkshaw, on Secret
Agent Radio. It appears that Rumpelstiltskin is the name of a band,
though, so not sure how I’ll find this particular track.
Edited to add: I found the album name on the Secret Agent Play list: Mo’Hawk - The Essential Vibes & Grooves 1967+1975

Soccer Stategy
I’m trying to learn more about soccer strategy, particularly with respect
to attacking. Here’s
a nice page with basic principles for attacking and defending. And here’s a
page from the National Soccer Coaches Association of America that talks
about different systems and how to match them to your team.

Randomized block experiments with multiple replicates
Unlike many experimental situations, with computer modelling the problem
tends to be an embarrassment of riches. There is no problem with amount of
data. You can gather scads and scads of data. So much so that it can be
hard to find statistical tests that deal with what you’ve got. Right now,
I have data that can be set up and analysed as a randomized block (or
repeated measures) experiment.
Here is an excellent description of randomized block ANOVA and how it
works. The problem is, I not only have randomized blocks, I have multiple
replicates within each block. Psychologists should be so lucky, right? But
no one seems to cover this case, because usually people are lucky to get
enough subjects to do a randomized block experiment with a single value in
each treatment of each block. So, what to do now? I could take the average
of the values and test those, or I could randomly pick one of my
replicates to compare. Both seem plausible. But what is the ‘officially
right’ thing to do? That’s my dilemma.

My modelling setup leads to a need to test paired data, probably using a t-test
for paired observations. Here’s a page on how that
works.

Vietnamese Desserts
I saw a picture of a dessert on the LJ food blog that Colin subscribes to
and had to learn more about it. It turns out that there are a whole slew
of wonderful sounding Vietnamese Desserts called ‘che’ something- for
example Che Ba Ba, or
Che Ban Lot, or Che Thap Cam. This
blog has a nice explanation of what’s involved. Coconut milk. That’s
what’s involved. And lots of gummy, chewy stuff.

Social Role Valorisation
I’m quite interested in the fact that different people are valued
differently in society and that certain properties of individuals
influence their value in one direction or another. Here’s
the wikipedia entry on Social Role Valorisation, a theory which seeks
to explain how valuation occurs and what the effects of being assigned low
societal value are on individuals.

Carbon/Silicon- The News
I heard this song

chorus that really got to me.
Good morning here’s the news- and all of it is good.
Good evening here’s the news- and all of it is good.
And the weather’s good!
What can I say, I have a soft spot for old school punk, and punk rockers.

Making International Calls
For some reason the details of making international calls occassionally
elude me. Or sometimes the person who supplies you the number gives you
extra digits or information that you need to drop when you call
internationally. While looking for information to call Colin, I found
this neat
website. You put in where you’re calling from, where you’re calling to
and it gives you the proper codes, up to the city code. It also gives you
time zone information. Nice!

Points on a sphere
I’ve been avoiding working this out for a while, but I need a way to
generate points on a sphere of a certain radius. That’s because my agents
are composed of spheres, and I need to set their perceptual fields at
points on the outside of the spheres.
It’s easy enough to figure out the general formula for points on a sphere- it’s all points that are the radius away from the center of the sphere. The problem I’m having is getting actual points out of that equation. Picking x and y points randomly is likely to lead to a situation where there is no z value that fits on the sphere. I’m sure there’s some easy way to do this but, as usual, my complete lack of education in 3d geometry is not helping me out here.
I found this
sphere FAQ which might provide some helpful info. I also found this discussion about
how to convert spherical coordinates into cartesian coordinates. And,
doing a bit more searching, I think
this will probably do the trick.

This
article on grains edible by people with celiacs has a very

to wikipedia, cereals or grains can be defined as “mostly grasses
cultivated for their edible grains or fruit seeds (i.e., botanically a
type of fruit called a caryopsis).”

Red fish, blue fish
I wasn’t sure whether or not to put this in the school or living
categories. Here’s a story
about using animated fish schools to understand cultural differences.
Cool. Here’s a quote: “Ellsworth proposed a hypothesis of “universal
contingency”—if people from different cultures or roles appraise a
situation in the same way, they will feel the same emotion. If they feel
different emotions, it is because they have interpreted the situation
differently in one way or another.”

Proper Disposal for Compact Fluorescent Light Bulbs
I have some reservations regarding compact fluorescent light bulbs.
Without saying any more about that, I encourage everyone I know to follow
these
safety guidelines if you break a CFL. The main one you need to know
right off the bat is: “Open a window and leave the room for 15 minutes or
more.” Another important one to know is: “Do not use a vacuum cleaner to
clean up the bulb (even if it lands on carpet).” Read on for more on how
to deal with a broken CFL.

Comparative Calorie Burning
I found this
nice calculator that calculates how many calories you burn for a
particular activity. It lets you put in your weight and how long you’ve
done the activity. What I find most interesting is comparing activities.
In particular, I find it interesting that doing pretty much *anything*
other than simply sitting burns way more
calories than sitting. I wasn’t expecting that. I thought there would be
more of a gradual curve. But simply switching to typing burns 50% more
calories than just sitting alone (or sitting on the bus, or sitting reading). Standing burns 225% more calories than
sitting. Walking burns 375% more calories. This explains why, when you’re
lost in the woods with no food they say- don’t move! Stay still until you
are found. And no typing!

The Elf Project- Divine Comedy, Wizard of Oz and more
Every once in a while I come across a website that makes me go- “Wow, the
internet is really, really cool.” Not that there isn’t a lot of cool stuff
on the internet regularly, but there are some things that seem really
unique to, and made possible by the technology of the internet. This week
I’ve stumbled across two sites like this- the first being the zebrafish
imaging site, and the second being the Electronic Literature Foundation
website. I came across ELF when I was looking for an online verison of
Dante. The website’s Dante section has 3 different English versions (along
with Italian, German and Finnish) and lets you compare all the different
translations side by side. The ELF site has a host of other authors’ works
available as well, including The Arabian Nights (two English versions) and
The Wizard of Oz.

Moon Rising Info and other events
I like to keep track of when the sun rises and sets, and since we checked
out the moon in my dad’s telescope I’ve been interested in moon rising and
setting as well. I realised the other day that although I often know when
the moon is rising and setting, I’ve never thought about where it rises
and sets. I noticed this when I was looking for it the other day. Here’s
some info on where it rises and sets. I also came across this
page, which has a calendar of astronomical events that are visible to
the naked eye and binoculars. I’ve become more aware of such things since
my dad is into astronomy these days, and keeps buying binoculars.

Fish Database
And also, a fish
database that I came across a while a go but forgot to add to my blog.
It has a page on zebrafish, with know information gained from research.
It’s interesting what sort of information has not been published on the
zebrafish. For instance, there appears to be no information available
about how fast zebrafish move, or how they move through the water. This is
data that I have, so I may be able to publish it, and contribute.

infinite.”
