Since my palindrome checking code is getting a fair few hits, I thought I would update it. The optional second parameter is now gone, because it was a lot of hassle for little reward.
Additionally, I thought I’d create a little interface for it. Behold, the Online Palindrome Checker. It’s just a simple form, but it works well enough.
Bonus: if you use the Gecko family of browsers, you can use the automatic search feature (outlined earlier) to set up a keyword to it. Personally, I use the rather obvious choice of “Palindrome”. You might want to try something else.
