From the website:
OCW shares free lecture notes, exams, and other resources from more than 1800 courses spanning MIT's entire curriculum. 
Wow. I may have found my new years resolution.

Some company creates the libraries and test facilities for writing MapReduce  programs. Then they provide a free program that people can download and run, like in . Companies would pay to have their programs run on the network, and the profits would be passed on to the individuals who's computers ran some of the processing ...
I know there are a lot of tiny details to get right, security, validation of results (IE, rogue machines purposely calculating invalid results quickly to game the system), but it feels like it could be insanely profitable.
Someone has to have thought of this already. If someone out there knows of this, please let me know.

Mostly it drew my attention to the types of algorithms that google uses for it's large scale processing. They're based on MapReduce  which is fascinating in and of itself, but also of Hadoop  which is google's open source java implementation of a MapReduce. Eventually I made it to  which looks like it's a fascinating read. I almost got stuck in a wikipedia feedback loop  but managed to escape by realizing that I should print and read the research paper instead of continuing.

It's now much easier to just download the bindings and start hacking. Included in the build are 3D rendering libraries, GUI libraries, Physics Libraries and some other surprises, like support for Caelum. This gives me much motivation to try to get involved again.

First, I need to be able to list directories and files on the side pane. Now, directory listings are part of every operating system I've ever used, and I figured that Gnome had solved this nicely by now. I first looked at the pygtk reference material, and nothing jumped out at me. So I figured I'd have a quick look at the filebrowser plugin that comes with gedit. First obstacle, it's written in C. Oh well, I have a good enough understanding of C so I grab the source. Wow, that's quite a few files. I start poking through them, and to my surprise, they were huge!
Running sloccount on the directory produces:
SLOC Directory SLOC-by-Language (Sorted)
7375 filebrowser ansic=7375
Totals grouped by language (dominant language first):
ansic: 7375 (100.00%)
Total Physical Source Lines of Code (SLOC) = 7,375
Development Effort Estimate, Person-Years (Person-Months) = 1.63 (19.56)
(Basic COCOMO model, Person-Months = 2.4 * (KSLOC**1.05))
Schedule Estimate, Years (Months) = 0.64 (7.74)
(Basic COCOMO model, Months = 2.5 * (person-months**0.38))
Estimated Average Number of Developers (Effort/Schedule) = 2.53
Total Estimated Cost to Develop = $ 220,187
(average salary = $56,286/year, overhead = 2.40).

7k lines of code!? To embed a filebrowser into an editor!? WTF!? It's not like this particular filebrowser implements any special features for the editor either. Besides, gnome already has a filebrowser. Nautilus. Surely nautilus provides an embeddable widget that can be re-used. And if it doesn't then why didn't this time get spent on making one for it! What is wrong with people that they figure re-implementing yet file management all over again is a reasonable use of their time?

However, I want to focus on a particular paragraph of his:
GPL fans said the great problem we would face is that companies wouldtake our BSD code, modify it, and not give back. Nope -- the great problem we face is that people would wrap the GPL around our code, and lock us out in the same way that these supposed companies would lock us out. Just like the Linux community, we have many companies giving us code back, all the time. But once the code is GPL'd, we cannot get it back.
Social issues aside, this section implies that it is the users of the GPL that are at fault for locking the BSD users out of re-using the dual-licensed code. However, the reality is that is the combination of the licenses that prevents it. The users of both licenses choose their licenses for a reason, and must deal with the ramifications, not the least of which is that BSD code cannot borrow from GPL code without changing the manner in which the BSD code may be used. So, when Theo chose the BSD he made a conscious decision to restrict himself from re-using GPL code, so ... it's not strictly the fault of the GPL users. The OpenBSD guys could choose and use a license which doesn't have this restriction if they wanted to.
In other words. The cause of the restriction is based on your frame of reference or point of view.

I'm an INTJ which, among other things, means that inefficiencies really get under my skin. In programming, I find that most languages get in my way more often than not. Python on the other hand has always made me more efficient for using it. Apparently, I'm not alone:
I've come to understand that with programming, it's not really about which language you use but what you do with it. Computers are fast enough today to trade speed for comfort at an acceptable level of performance. After all, a programming language should work for you, not bury you.
"With Python, the code gets out of my way, so I can get to the problem am I actually trying to solve, very soon." -Bruce Eckel
