Tool for Debugging HTTP POST Requests

While evaluating MailChimp as an email service provider I noticed they referenced a tool which is useful in debugging HTTP POST requests.
http://www.postbin.org/

PostBin lets you debug web hooks by capturing and logging the asynchronous requests made when events happen. Make a PostBin and register the URL with a web hook provider. All POST requests to the URL are logged for you to see when you browse to that URL.

Cygwin Spam Trap

Just noticed that Cygwin home page has a spam trap at the bottom of the page. The following block of text is not visible to humans on Cygwin's page because it is white font on white background. I have not noticed many sites doing this, so is it common practice and I have just missed it before now? I wonder how well it actually works because I can not imagine it works very well for "blocking".

URLEncode and URLDecode Using Javascript Bookmarklet

I find myself frequently needing to quickly URL encode and decode values. Here are two bookmarklets that prove useful for doing just that.

Encode:
javascript:if(i=prompt('String to encode:'))prompt('Encoded:',encodeURIComponent(i))

Decode:
javascript:if(i=prompt('String to decode:'))prompt('Decoded:',decodeURIComponent(i))

Yahoo! Decides To Un-Deprecate Term Extraction Web Service

By Popular Demand, We’re Keeping the Term Extraction Service

Apparently, many developers take advantage of this web service provided by Yahoo. I like the fact this particular service is integrated directly into Yahoo! Pipes. The module in Pipes allows for automatic keyword tagging of content within a feed.

Java Web Start Running on Ubuntu Linux

We use Java Web Start to deploy a few of our Java applications. However, the Java Web Start that comes packaged in the default Java SDK with Ubuntu does not configure itself out of the box. Instead of going through the hassle of manually configuring the default Java Web Start on my laptop, I simply chose to install the Sun Java6 JDK on Ubuntu. This has made life easier.
The jnlp files now work properly on the system.

How To Setup 301 Squirm Pattern

Assuming you already have squid cache configured and are using squirm as a redirector, it is simple to add 301 redirect paths.

Here is an example:

regexi http://www\.example\.com/example_redirect   301:http://www.example.com/new_location

Squid will return the appropriate 301 HTTP header location. Alternatively, you can set any of the redirect HTTP status codes in the response header.

Google urchin.js Contains List of Organic Search Engines

The Google Analytics urchin.js contains a list of search engines and their query parameter. This can be useful to me as I build Javascript code to examine keywords used to arrive on our pages from search engines and then present additional related content based on those keywords.
