I too am willing to help and serve on the committee. - Randy Stern Manager of Systems Development Office for Information Systems, Harvard Library -- Date:Mon, 19 Dec 2011 14:08:22 + From:Friscia, Michael michael.fris...@yale.edu Subject: Re: Subject: Re: NEcode4lib? I guess if we can nail down a list of people willing to help plan so we can get past the three basics, planning committee list, when and where this will happen. So to get the ball rolling, please respond to say if you are willing to help plan and can commit to at least two hours a week leading up and effectively be on the planning committee. If you'd like to help plan but don't want to be on the committee, respond saying that. I'll start by saying, I'll help and am willing to serve on the committee. ___ Michael Friscia Manager, Digital Library Programming Services Yale University Library (203) 432-1856
[CODE4LIB] math problem
Here's a brain teaser for the mathematically inclined:
I've got a set of values that I want to scale to the 0-255 range so that I
can adjust colors in my CSS.
Say I have the following data: (6, 457, 97, 200, 122).
I'd like to scale those numbers so that the highest one, 475 = 255.
and the lowest one, 6 = 0.
All of the other numbers, 97, 200, and 122 should be scaled proportionally
to fit within the range.
This way, when I loop through and hit my CSS {background-color:rgb(255,
**data**, 255);} each piece of data will generate a different color and
I'll have the maximum spread in proportionally correct colors from 0-255.
There's probably some math operation to do this, but I know I paid far too
little attention in math class as a kid. When will I ever need to use
this stuff in *real life*, I asked the teacher with a sneer.
If anyone could point me in the right direction I'd appreciate it.

Re: [CODE4LIB] math problem
Off the cuff, I think you're looking for
f(x) = (x-m) * 255 / (M-m)
where M is the maximum in the input data set, m in the minimum, and x is the
number in hand.

I'd need to see exactly what you're doing, but I think this method may
leave you somewhat unsatisfied. The magenta-white color scale isn't
gonna be lovely, and there's no sense of absolute scale to this
technique. Maybe that's what you want, but... probably not. You might
want to say Hey, values are supposed to be from 0 to 450; anything
outside this range should be clamped. Or highlighted. Or something.
Anyhow, for perceptually good color scales, this is a great resource:
http://colorbrewer2.org/
... and if you want a good way to generate color ramps in javascript,
the most excellent d3.js library will help you out:
http://mbostock.github.com/d3/
In this case, to create a scale like this, you'd do:
var data = [6, 457, 97, 200, 122];
var color_scale = d3.scale.linear().domain([d3.min(data),
d3.max(data)]).range(['#FF00FF', '#FF']); // we're expecting data
from 6..457, and will output magenta to white...
console.log(color_scale(6)); // rgb(255,0,255);
console.log(color_scale(457)) // rgb(255,255,255);
console.log(color_scale(500)) // rgb(255,279,255); //oops!
color_scale.clamp(true);
console.log(color_scale(500)) // rgb(255,255,255); //better!

Re: [CODE4LIB] math problem
Thanks Nate- I'll get this working and check back with these other options.
I've got a top 25 list of fiction titles, and I'm making a set of divs
change color according to how many times they've been checked out. If it
looks bad and it's a lousy approach no doubt I'll try something else.

Re: [CODE4LIB] Islandora Announces 11.3.0 Release
I was wondering what Islandora is. Here is the description form the about page: Islandora is an open source framework developed by the University of Prince Edward Island's Robertson Library. Islandora uniquely combines the Drupal and Fedora open software applications to create a robust digital asset management system that can be fitted to meet the short and long term collaborative requirements of digital data stewardship.

[CODE4LIB] Drupal panelists needed for ALA Midwinter!
***Apologies for Cross-Posting*** We could still use 1-2 more folks to serve on the LITA Drupal Interest Group's Fail Panel, which will take place during the IG meeting on Saturday, January 21st from 1:30-3:30 pm. Virtual participants are welcome; this IG has presented pre-recorded presentations and Skyped folks in very successfully in the past, so even if you're not going to Dallas, we'd love to hear your tale of Drupal fail! More information about the fail panel is available here: http://groups.drupal.org/node/193583 Also, the purpose of the fail panel is not to blame, assign fault, etc., about Drupal fails, but to educate others and help them avoid the same mistakes. The format--a series of slightly silly, yet insightful, questions asked by an emcee--is fun and light-hearted, so it's a snap to prep for (you'll get the questions ahead of time) and fun to do. And don't worry: the audience will be groaning along with you, not laughing at you! -- Nina Nina McHale, MA/MSLS milehighbrarian.net Facebook Twitter: @ninermac
