While experimenting with mobile development on the Blackberry Webworks Platform I found that it was extremely difficult to get any debugging information out of the device simulator to help debug javascript errors.
I’ve been looking at using Phonegap and Dojo for rapid application development on mobile devices. As I have been doing blackberry development for the past year or so I thought that this would be a good platform to start on. However, I almost immediately ran into a problem with the WebWorks packager.
I’ve found myself moving more and more towards GIT, both for its multiple upstreams, offline editing abilities and sane merging. However, I haven’t been able to find a Zend Framework 1.x repository. As a result, I am hoping to maintain a clean one using the svn2git tool. Check it out on github:
http://github.com/51systems/Zend-Framework-1x
Expect updates to be pushed to it for each release in the 1.x line.
One of my recent PHP projects had the requirement to filter out inappropriate language from user submitted content. After thinking about the problem briefly, I decided that I didn’t want to be writing the filter myself but, rather, find a third party service that could filter my text for me. By doing this, I eliminated the need to create and maintain a bad-word list, as well as saved the CPU cycles required to actually preform the search-and-replacement (Although, arguably, remote API calls are more expensive anyways).
There are a lot of web-sites out there, with a lot of data on them. Sometimes you are building a killer web-app and you just have to have some data off a certain site. The problem is, that particular site doesn’t have an API that you can just plug into! Never fear, using some simple tools, combined with the Zend Framework you can create your own web-scraping (screen-scraping) API in no time.
Back in 2007 I wrote a post on how to integrate Dojo with Greasemonkey.
Since then, Greasemonkey has been re-written to include security and bug fixes which has broken my demo code. The problem is that the new security model doesn’t return an instance to the newly created dijit.Dialog when the constructor is called. The work-around is to set the ID of the dialog, and then call dijit.byId() to get a handle to it.
In Computing science artificial intelligence terms, the game of Sudoku is a constraint satisfaction problem. Constraint satisfaction problems are nice in the regard that there are some very nice heuristics that lead to an easy algorithm to solve them. On the other hand, constraint satisfaction problems with a large problem domain may take an inordinate amount of time to solve.
I’ve been playing around with ShellInABox and I think it is quite neat. From the website:
Shell In A Box implements a web server that can export arbitrary command line tools to a web based terminal emulator. This emulator is accessible to any JavaScript and CSS enabled web browser and does not require any additional browser plugins.
Translink is the local public transit provider for beautiful Vancouver, Canada. The system consists of Buses, Boats and Trains. Translink released an Iphone app some time ago that allows the lookup of bus information. Michael Weisman was kind enough to write about the “hidden” api that is used by the Iphone app to preform AJAX calls.
Sometimes it can be handy to inject Dojo into pages that would not otherwise have it. I’ve used this so I can use dojo.query() on a page to select DOM objects while testing a parser in a different language.
