v2 of simple d3 with Meteor – now rendering individual records

In Uncategorized on June 8, 2013 at 3:17 pm

simplest d3 + meteor example I could make v2

steve/simple-d3-with-meteor · GitHub.

Learning meteor & d3 together – I wanted a simple example to build on. Since I didn’t find one, I’m sharing this. The minimal (for me) was that it took advantage of the reactive data synced between client & server to affect something I drew with d3.

Now, individual circles are drawn by d3 (via a template), each one as a result of individual record changes managed by Meteor. This is more like what (I think) Meteor intended, as it’s much closer to how HTML is created by Meteor templates. One difference, the removal of something from d3 is triggered by use of a callback from observing the Things collection.

  • Add & remove records in “Things” collection using the “+” and “-” buttons
  • Each record in the “Things” collection will be shown as a circle, with the “name” attribute as the text inside of the circle.

SNAP! – Programming for Kids

In Uncategorized on April 15, 2013 at 2:07 am

SNAP! (Build Your Own Blocks).

We’ve had great fun, and results, teaching kids to program with Scratch. Now, Berkeley has “an extended reimplementation of Scratch … that allows you to Build Your Own Blocks. It also features first class lists, first class procedures, and continuations. These added capabilities make it suitable for a serious introduction to computer science for high school or college students.”

I’ve only played with it a little – but getting started with Snap! is even easier than Scratch – because it’s browser-based (i.e. written in  Javascript  and designed to run in the browser).

You can try it right away and it’s worth it – even if you’re not a kid.

FYI – we have a google voice number for Food on the Table -and forward it to our SkypeIn number.  However, at some point we realized that it wasn’t working. No matter what we did, we could not get a call to go thrugh Google Voice to SkypeIn.

Fortunately, I found an answer we had Skype set so that it  would only”Receive Calls to my online number” from people in my contact list.

Fix for: can’t use fluid with campfire anymore…

In Uncategorized on January 19, 2010 at 9:31 am

Now that 37signals centralized their user management, my existing Fluid-based campfire doesn’t work. Specifically, I can’t login because it keeps opening a new window in my regular browser to login, instead of completing the login within Fluid.

I googled for “can’t use campfire with fluid” and similar, and no luck.  A little more digging and I found reference to Making Fluid Ssbs Browse Only Pages You Want – fluidapp | Google Groups.

All I had to do was to add *launchpad.37signals.com* to my whitelist of URL’s to browse in Fluid and it worked.

I’m posting this here so the next person may have a shorter route to find the answer.

For Leopard, installing Sphinx from ports with mysql binary from mysql

In Uncategorized on September 4, 2009 at 11:57 am

Given I’ve installed sphinx

And I’ve used mac port for the install

When I run sphinx  indexer

Then it expects the mysql socket to be in /opt/local/var/run/mysql5/mysqld.sock

Given I’ve installed mysql

And I’ve used the binary from mysql

When I run mysqld

Then it use the mysql socket in /tmp/mysql.sock

To get sphinx indexer to use my installed version of mysql, I have to change make a change in the sphinx.conf file to tell sphinx indexer to use the mysql socket in /tmp/mysql.sock:

in some source …

{

sql_sock = /tmp/mysql.sock

}

Check  sphinx_docs [SphinxWiki] for reference.
