I am working on a small screen-scraping utility written in Ruby, and since I have been working previously with RubyfulSoup, I wanted to give WWW::Mechanize a try this time. So i have installed the WWW::mechanize gem: sudo gem install mechanize I wanted to try a ‘Hello world’ application first, to see wheter it works. Here are some official examples (click on ‘Examples’). I Copy&pasted the first on
I am guessing 9 out of 10 of you reading the title is prepared for yet-another Rails drama on some obtrusive community members, and because everyone is tired of Rails dramas, I am risking that some of you won’t care to read the article - but I couldn’t resist :-). Actually I’d like to talk about usage of (un)obtrusive Javascript - why is it a bad idea to be obtrusive, especially given that (as you
While I know the title is both asking for trouble (because of the now anecdotal original article with a similar title) and flamebaity, please read on - my goal is not to get some great stats but rather to know your opinion about the situation and discuss the possible solutions of the problem. How it all started… I would not like to re-iterate what has been said on several blogs, just to summarize:
I planned to do a writeup on the talks @ FOWA Dublin, but Dave Concannon did such a great job that I could not add too much without re-iterating what he said, so I’d like to concentrate on just one talk instead, which totally blew me away: Creating Software in the Real World by David Heinmeier Hansson. Let me start with a bit of background - as a Rails developer for almost 3 years now, this was o
I needed to add an AJAX grid/table component with all the bells and whistles (AJAX sorting, pagination, multiple row select, AJAX add/delete etc) to an application I am working on right now (will blog about it when we roll out a good-enough version). We are using jQuery so I started looking for a suitable plugin. I believe I have found it - it’s called jqGrid and it’s super sexy, feature rich and
“It’s better to be a pirate than to join the Navy” (Steve Jobs) This post was inspired by the last part of Jim Neath’s article on speeding up Rails development, titled “Seriously, Just Buy a Fucking Mac”. Some commenters insisted that you can do just as well on other systems (Ubuntu, in particular). In three short words, I don’t agree. In my opinion Ubuntu is a valid alternative but it comes in at
If I had to choose the single most not-really-well-understood, mystified, unsuccessfully demystified, explained and still not-really-grasped topic in the Rails world (and beyond), my vote would definitely go to REST. It seems to me that there are two types of people in the world: those who don’t get REST (and they think it’s a basic postulate to rocket science explained through quantum theory) and
This article is a follow-up to the quite popular first part on web scraping - well, sort of. The relation is closer to that between Star Wars I and IV - i.e., in chronological order, the 4th comes first. To continue the analogy, probably I am in the same shoes as George Lucas was after creating the original trilogy : the series became immensely popular and there was demand for more - in both quant
Update: A lot of things happened since the publication of this article. First of all, I have updated this article with HPricot and scRUBYt! examples - then I wrote the second part, I hacked up a Ruby web-scraping toolkit, scRUBYt! which also has a community web page - check it out, it’s hot right now! Introduction Despite of the ongoing Web 2.0 buzz, the absolute majority of the Web pages are sti
