To Infinity and Beyond

Sigfpe made the effort to collect many of his great blog posts he wrote over the years into a single, structured post. Basically writing an index. He covers Monads, Comonads, Fold, Unfold, the general Category Theory. I've been reading and rereading for weeks and there's still more to discover. Check it out here.

Update: Lucid Lynx on the HP Mini 210

Bye Bye Koala, Hello Lynx

Some time ago, I installed Koala on my HP Mini 210. Shortly after the next Ubuntu version "Lucid Lynx" was released. So I upgraded in hopes that some the hardware would be better supported. So I figured I should write a quick update about how things are.

Improvements

Bluetooth

Bluetooth works consistently now even after many suspend/resume cycles. This is definitely an improvement for people who need Bluetooth enabled peripherals. 

Remaining Problems

No Multitouch

Unfortunately there still doesn't seem to be touch pad drivers which support multi-touch properly. Normally I wouldn't care much. But the way the Mini's touch pad is designed makes this a bit of an annoyance. The left and right mouse buttons are embedded in the touch pad. This means that the cursor jumps around the screen every time I touch the pad with a second finger. Unfortunately this happens all the time when I point and click. 

Short Battery Life

Sadly, the one improvement I was hoping for hasn't happened. Even relying on powerttop to reduce the power consumption, the battery life is still only about two thirds of what it should be. I also figured out that shutting down the wireless controller before suspending, reduces power consumption while the netbook is suspended.

Conclusion

So that's that. Lucid's hardware support has improved compared to Karmic. That and the new look and additional features speak for an upgrade.
