I don’t know, but I do remember learning from an educational song from my high school years that in World War II the average age of the combat soldier was twenty-six, in Vietnam, he was nineteen.
The bonus feature in my patch series adds the magic file /sys/kernel/notes. Reading this gives you the binary contents of the ELF notes section built into the kernel. Here you can find the build ID of the running kernel. This gives a solution to a problem that has arisen for systemtap users, where nothing prevents them from using the kernel-debuginfo.i586 data to drive Systemtap’s probe details, but are actually running the kernel from the kernel.i686 rpm. This is a failure on many levels, but some simple sanity-checking at the bottom always helps. Now it is easy to verify you have the right debuginfo file for the kernel you are running.
If you can afford the space or whatever, and want one, get a pizza stone. I have never used one, so I can’t comment on it. I have used my 12" cast iron to make a lot of pizzas and there are many “cast iron pizza” recipes out there. It’s super easy and it’s one of the very few things that I can say I’ve yet to totally screw up cooking.
If you don’t have a cast iron pan, you should get one. A basic Lodge does the job as good as any (it’s just a hunk of iron). It’s super easy to use a cast iron pan to make pizza.
