Created a new blog on 4.25 with all the required configurations. Then I've tried to export all the entries on 3.25 and imported … Continue reading Migrating MT 3.x to 4.x and preserving BASENAME
I always wanted to know more about the customized Google servers. The cool part is that they have implemented a distributed UPS (each server has his own battery and charge controller): Instead of having a centralized UPS, Google integrated a battery into every server with a charge controller and test circuit. The battery is sealed … Continue reading Google Servers
