Upgrade from 32-bit to 64-bit Fedora Linux without a system reinstall

Filed under

One great thing about Linux is that you can transplant a hard disk from a machine that runs a 32-bit AMD XP processor into a new 64-bit Intel Core 2 machine, and the Linux installation will continue to work. However, if you do this, you'll be running a 32-bit kernel, a C library, and a complete system install on a processor that could happily run 64-bit code. You'll waste even more resources if your new machine has 4GB or more of system memory, and you'll be forced to either not use some of it or run a 32-bit Physical Address Extension (PAE) kernel. Cross-grading to the 64-bit variant of your Linux distribution can help you use your resources more wisely.

This happened to me with a Fedora Linux installation, and I finally decided to migrate. Over the years, I've talked to Fedora enthusiasts and Red Hat employees at Linux conferences about doing a cross-grade to 64-bit. I generally heard one solution: reinstall. However, I like to reserve this approach for when a critical number of system disks fail at once and I have absolutely no other option. I wanted to see if a cross-grade was feasible at a whole distribution level.

Moto 360 (2015) Review: The Most Watch-Like Android Wear Device Yet

Motorola kicked off the age of Android Wear when it announced the original 360 more than six months before it was finally released. It was a beautiful piece of hardware, but was saddled with an ancient TI OMAP ARM chip and recessed lugs that led to cracked back panels. The second generation device addresses many of the shortcomings of that wearable, but some of them are still staring you in the face. Still, it might be the watch you've been waiting for. Read more
