Google Wave for collaboration

This is probably going to be a hit. A real-time (yes, an actual real-time) collaborative environment where users can chat and stuff shows up as typing commences. There is so much more, though. Dragging and dropping pics, multiple edits on a single buffer, internal/external extensions, and playback of all activity that occurred in a wave (or wavelet?).

I have signed up for the API. Will let you know how it goes!

Software Design Principles - SOLID

The SOLID software design principles weren't called SOLID while I was in grad school, but the concepts were there in my Object Oriented Design course. They're worth mentioning here, primarily because I think once you start coding and become dangerous, it's one of the best ways to stay organized once you incorporate it into your daily coding routines, and it even changes your way of thinking for the better: https://en.wikipedia.org/wiki/SOLID

Matlab and MySQL

I had a lot of data in a MySQL database that I wanted to analyze. I had a copy of Matlab, so I figured the best way to look at this all would be to plot this data and use some GUI elements to go through various combinations. After some Googling, I found this database connector that seemed to do the trick. I downloaded the files, configured mex to use MSVC 2008, built the connector, then I was able to successfully connect over the network! I ran into two problems, though: The connector does not support fetching columns of type TIMESTAMP, and With the magnitude of data (about 180k rows), access times were really slow. I was able to solve problem #1 by changing my columns to DATETIME, which was supported. I'm still trying to figure out problem #2. It may come down to importing all the data directly into Matlab.

The TL;DR guide to git

While in the past I've held a pretty high opinion to using mercurial for version control, the majority of version control these days seems to done in git. Here were the commands I found most useful to get productive with git right away. # Clone a repository from an origin, i.e. my github MaskingUtils repository git clone git@github.com:caelumvox/masking-utils.git # Add a file after it's been updated to stage it for commit, or add a new file git add filename # Commit the file to local repo git commit # Push the file to the origin so the rest of the team can see it git push # List all locally tracked branches git branch git branch --list # Get a list of all branches from the remote git branch -r # Create branch locally git branch develop # Push the branch to the origin repository to make sure it is tracked there git push --set-upstream origin develop # Pulls latest from all local branches tracked from origin; won't pull non-tracked branches git pull --all # Fetch the branch
