The Time Machine
Browser has become one of the most important piece of software in human life. Take one example, me. I use web based application to track a project. One day, I can't access the website. I was literally pulling my hair trying to figure out what's wrong. The ISP? The web? The whole internet broken?
After a dozen of refreshes and restarts, I am somehow able to access the site now. After I log in, I see something wrong. The CSS and JavaScript files were not loaded. The site is a AJAX-heavy site (which is cool), but has no alternative when the browser can't load JavaScript. See, the J in AJAX is JavaScript, and it's not AJAX if you can't do the J. In conclusion, I can't see or update my task list, I can't do anything for two days.
I tried re-installing Safari, tried with Firefox (two different versions of it), nothing worked. 3 am in the morning, in desperation I pull one last trick. Time machine. I restore Safari and some of its configuration files from a few days back (before the latest update), and shutdown the computer (without trying opening that damn site again, too tired). Later that day I tried again, and to my surprise it worked. Life is good again. Now I can continue my life.
