Long-term Memory

The graphs of the ESC logging data I made earlier aren’t as pretty as HTML5 allows… So I retried it using HighCharts and a bit of JavaScript. The result is a standalone LogViewer page which interprets and graphs the log data entirely client-side. The page itself is fairly boring until you feed in a log file.

Clearly I’m not a layout specialist, but the functionality is there.

There has been a lot of fud lately about the privacy of your browser-history. JavaScript can detect which URL’s you have visited and act accordingly. This can range from a useful script to only show the social networks you actually use, or a site that lists your history. However, nothing is stopping the JavaScript to “call home” with this information.

I too was a bit worried about this potential privacy breach. Obviously there are several solutions and workarounds:

• Systematically clear your browser history
• Use a sort of private browsing mode
• For Firefox: Disable layout.css.visited_links_enabled in about:config. This completely disables visited-links, so you won’t be able to see which sites you’ve visited
• For ancient Firefox 2.0: SafeHistory extension
