I’ve developed a small PHP script that can act as your own personal hiragana and katakana tutor. What it does is simply displaying a number of random romaji like “n go ho yu do wo pe hi chi ko” and then you simply write the answers on a paper. If you do not know the correct kana just press “Answers” and you’ll get them!

I’ve written an extension for script.aculo.us. It’s a simple inPlaceEditor for date & time fields. I creates one select box for each: Year, month, day, hour and minute.
