I just wanted to brain dump a few things I thought were interesting and worth looking at more deeply. This is just so I don't forget about them.
Making kvm images
I got this from Linux Journal's August 2009 issue, in Serge Hallyn's article on Making Root Unprivileged:
- qemu-img create f10.img 6G
- kvm -hda f10.img -cdrom f10.iso -m 512m -boot d
Wow. Is it really that easy? Maybe I should dump vmware…

Turns out it is just that easy. Except I think Serge had kvm aliased to qemu-system-x86_64. The boot is very fast though you'll still run into the typical VM problems of memory limitations that slow the F11 install, for example. Take a look at the KVM Howto to see how to use this cool feature.
FreeRTOS
This is an open source mini-real-time kernel with preemptive multitasking and coroutines. This may come in handy for some of the hardware projects currently underway at work. I could always use real-time Linux, but this may be a lighter-weight option. The same issue of lj has an article on the -rt patch to the kernel that adds a real time Linux scheduler. There are some interesting links in the area of real time Linux I should look at:
Cool Devices and Software
These are some projects I need to look at a little deeper. They may offer some options to projects we bid on at work. And some are just plain cool.
- The Bug – read the LJ article on this device.
- NeatX – google's open source port of NX, the “lightweight” X alternative.

- mingw32-gcc – F11 added this compiler to the distro so you can do (yuck) Windows builds on F11. That would be cool for work where we need to compile JNI code for windows. Previously, we'd have to launch a VM and rebuild the JNI code. I'm not sure how this compiler handles the DLLs – probably have to have a Windows partition somewhere. But I hope not.

- The peek – This is a small handheld, essentially mail-only device. What's cool is the price – about $19 on amazon – and the fact that they want someone to port Linux to it. Sounds like fun.
I'm sure I have others floating around my many notes and saved emails, but that should keep me busy in my copious spare time for the near term.
