On my way back from Uppsala, my mind wandered to a conversation I had with a collegue about the intuition of monads, which I pretty much butchered at the time. As I was mulling this over, it dawned on me.
monads are fractals
The above is a fractal called Sierpinski triangle, the only fractal I can remember to draw. Fractals are self-similar structure like the above triangle, in which the parts are similar to the whole (in this case exactly half the scale as parent triangle).
Two days of #ScalaMatsuri ended as a huge success. But for the next year, I'm leaving ourselves a few homeworks to work on. As the title suggests, the next goal that we should aim for is universal access. In Scala language, universal access principle indicates the fact that both methods and fields can be accessed interchangeably from outside.
For a conference, I mean universal access to mean being more inclusive to various groups of people:
This year was the second Scala conference in Japan. We've changed the name to ScalaMatsuri, which means Scala festival in Japanese. 300 tickets sold out. With invited guests and free tickets for sponsors, there may have been even more people. The venue was at CyberAgent, which runs blog service and online ad services.
Personally, I don't mind using SublimeText, which is my editor of choice for a while. But I'm also curious about commandline editors since many people taut their ability to code over the network. You could forward X or remote in using some other way and still use Sublime, but let's see how if goes.
I started working on this Vim setup when I got a new MBP recently. Figured, I can try something new. So, this post is more of a personal memo written by a total newbie, which is what blogs are all about. caveat emptor. In general though, the configuration is mostly inspired by yuroyoro-san's blog post from a couple years ago.
various non-vim things
The setup described in this post is checked into eed3si9n/dotfiles. It is encouraged to fork other's dotfiles, but I wanted to understand what settings I'm bringing in, so I wrote mine from scratch.
The general idea of the dotfiles is that it will be checked out to ~/dotfiles/, and contains files like zshrc. These root-level configuration files are then symbolically linked under the home directory as ~/.zshrc.
The need for regular expressions is real. Whenver I need to transform a set of text files it usually ends up with fumbling through the documentation of find command, zsh, and StackOverflow Perl questions. I would rather use Scala instead of muddling through Perl. It's really the matter of my familiarity than anything else.
For example, I now have over a hundred reStructuredText files that I want to convert into markdown. I first tried pandoc, and it looked mostly ok. As I was going through the details, however, I noticed that many of the code literals were not converting over as formatted. This is because they were formatted using either single ticks or using Interpreted Text. Preprocessing the text with a series of regex replacements should work.
