Computing Life

[Update2] I used the library eigen to reimplement the algorithm, reducing the code from 84 lines to 41 lines (wow), and time increases 11%. Looks acceptable, with similar workload as unoptimized C#, but the same speed as heavily optimized C# (with 164 lines of code and unsafe compilation). What's even …

Finally time for an upgrade of our Beamer Writer. I added two features recently.

• Support of equations. Now when you enter \[x^2\] in the input textbox, it will be rendered as it is, i.e., \[x^2\] rather than \item \[x^2\] like we did before. This will make …

Github is a well-known tool within the dev community. People use git(http://git-scm.com/) and github to collaboratively build awesome stuffs and also enjoy the social life (xD, geeks). I find it also useful in our daily research, say, to host a paper reading seminar. (I assume you are …

I was interested in F# because of some of its fun usages, and the ease to do asynchronous and parallel computing. Used F# to implement some domain specific language like Turtle and fractal effect this afternoon. Basically the tasks themselves are nearly the same as this post and this post …

Just finished the final of convex optimization. This is really an interesting course, which even changed the way I'm looking at this world. In college, I was thinking in an algorithmic way, i.e., to solve a problem, will try to design some certain steps, following which we can get …
