stuff: Node.js means having to put your toys back in the closet after you're done :(

http://blog.vishnuiyengar.com/2010/09/nodejs-means-having-to-put-your-toys.html

Thursday, September 30, 2010. Nodejs means having to put your toys back in the closet after you're done :(. When I was first exposed to Ruby and how easy it was for functions to accept blocks and how ubiquitous such functions were, I was delighted that for example. Fileopen { file foo(file); bar; baz; qux;}. And then recently this. Post on Stack Overflow. Led me to this code sample in Node.js. The code is opening a file and appending the word world. I have to remember to close the file! Or maybe fs.o...

stuff: Changing the Rules

http://blog.vishnuiyengar.com/2010/10/changing-rules.html

Sunday, October 3, 2010. Evented programming with nonblocking I/O. Every time an I/O operation starts, the system registers your callback and continues on. Once the Input or Output operation is completed, the callback executes. So every time. You intend to do any input or output operation, you put the code that's meant to execute after it is done. In the callback. But, this means, that in any interesting program, a large part of it is going to be spent in nested callbacks. Sequence, Selection, Iteration)...

stuff: Silly Mistake

http://blog.vishnuiyengar.com/2010/10/silly-mistake.html

Wednesday, October 20, 2010. So recently I stumbled across this webcomic Wonderella. After I read a few pages, I decided to do what I do with all webcomics I like, . download the whole thing. Because I can't stand that 30 second - 1 minute wait between pages. Previously, I used to do this sort of thing with wget, and try to discover the rule, and invariably there would be some complication or the other. Then I wised up and started using Mechanize. About evented I/O a bit now, someone on the Node.js.

Sunday, October 31, 2010. Introducing StepRewrite (aka I finally understand macros). So it's finally done! I could probably do a bit more, but for the moment it's working and packaged! For a while now, I've been writing about a problem I want to solve. And discovering the tools. To solve it. Of course it's also a problem that may not really exist, but fuck it! To really understand the motivations behind this thing I've built, follow those links above, but here is the short version. So step rewrite, Can b...

stuff: Beware ActiveSupports Default Autoload Mechanism

http://blog.vishnuiyengar.com/2010/09/beware-activesupports-default-autoload.html

Wednesday, September 15, 2010. Beware ActiveSupports Default Autoload Mechanism. By default active support sets its dependency loading mechanism to load rather than require. We're working on a non rails app with datamapper and some models add before :create hooks. If you dont take care, these models are loaded twice and the hooks are added twice which can result in strange behaviour. So remember to do this ActiveSupport: Dependencies.mechanism = :require.
