Choppr ins an extension for Opera that adds a short flic.kr-url to the right hand column on a Flickr™ photo page.

This short url is calculated from the photo's unique id (actually, the calculation is ”bijective“, thus could be inverted) – there is no web service contacted during that process.

You find the short url behind a little ☆-icon below the photo's license statement and above its privacy information in the right hand info column.

The Google Analytics-API provides a new feature, that allows a webmaster to instruct the Google Analytics tracker (that is constructed by of a tiny piece of Javascript code embedded in the web page's markup) not to store the last 8 bits of the IP address of you, the visitor.

This UserScript checks each inline script embedded in a web page, whether a Google Analytics Tracker is constructed therein. If that is the case, it surgically inserts an Analytics-API call to the _anonymizeIp() function, thus requesting the masquerade of the IP.

New: As an experimental feature you can also enable the handling of asynchronous trackers. A call to _anonymizeIp() is pushed into the _gaq command queue in these cases.

You may consider it one step in direction of an alternative to the Google Analytics Opt-Out Addons available for other major browsers.

As of version 10.50 and 10.51 there is still no Geolocation API support built into Opera – the short intermezzo in some development snapshots left aside. Thus I wrote a UserJS to address this issue. It returns a hard coded geographic position via a standard Geolocation API if requested by the browser and if permitted (on a case-by-case basis) by the user. So it's mostly useful for peoples hardly-moving desktop machines. ;) It supports the geolocation methods getCurrentPosition(…), watchPosition(…) and clearWatch(…) as well as the interfaces Position and Coordinates for the returned objects up to the point it's reasonable for a static, ie non-moving, geographic location. Thus it virtually emulates the W3C Geolocation API Specification (Editor's Draft 10 February 2010).
