More injured Bilbys - 13:25
Two weeks ago I Wrote about Gary Rolfe breaking his arm mtb riding. Alas it seems injuries are happening to Bilbys currently. Last week a car drove into the middle of the southside road bunch and Ulisses Da Silva suffered a broken collar bone in the resulting collision, Uli is another Bilby (and like me a committee member). Today during the Wednesday morning Bilbys road ride there was another injury. Riding around a corner, damp from rain, both the wheels on my road bike lost traction, I thought for sure I was going to have a nasty crash, I don't know how but somehow I kept the bike upright. Unfortunately Ron Brent was not so lucky, he went over hard. Hitting his helmet and breaking it, gaining some serious road rash on his right leg and dislocating his right shoulder. We all waited with him until someone was able to give him a lift to the Hospital. I hope you get better soon Ron.

Update: I talked to Ron soon after I posted this entry. His shoulder popped back in before he got to the hospital, which is good. However there is some tearing in ligaments and tendons plus some strained muscles so he is out of action on the bike for around 3 weeks, and out of swimming for a bit longer. Ron mentioned it doesn't hurt at all while sitting or lying down now, and hurts a bit when standing due to the sling on his sore neck muscles.

Update: I also never said what happened to Gary Rolfe. Gary's Radius was shattered in three places, his wrist was pulled off the ulna a bit also. So tendon and ligament damage, they had to shove it all back together and then pin the radius up with a few pins (operation). The doctors considered him lucky not to have broken the Ulna, also they commented his bones were in very good shape on the whole. Probably in large part due to being incredibly fit and a healthy diet with good calcium intake. Gary got a new cast made of fiberglass on friday as the swelling had gone down enough. The cast probably comes off in about 8 weeks.

Both Gary and Ron are busting to get out training again soon as you can imagine.

More on the Linux v Sun discussion - 11:25
This morning I notice in Miguel de Icaza's activity log he makes mention of the Sun and Linux kernel discussion I have talked about Previously. Miguel suggests Greg KH is missing the point. I am not so sure, Greg was not as Miguel suggested arguing with the "everything we do is fine, there is no need to improve" viewpoint. Greg is a well balanced guy and looking at the crap he has dealt with on LKML and other places over the years he definitely seems to understand and respect other viewpoints and will change when a technically correct and superior change is displayed.

Miguel commented about Greg rejecting the Sun guys API stability arguments. I don't know that he rejected them so much as pointed out that that the API is stable in the kernel <-> userspace interface and has been for many years. Kind of like GTK or Mono or something having published API's and having internal structures. There is not much software if any that needs to use internal structures and such with those libraries. In the kernel though if someone has out of tree kernel code it has to keep up with the kernel internal structures. Andrew Morton has talked about this issue at OLS this year as have various other people, code that gets into the kernel will be maintained.

Of course the trick then is getting your code into the kernel, to do this you really need to grok Linux kernel culture and work with it. Mikal pointed out there seem to be exceptions where Linus or others appear arbitrary. Such as FUSE which Mikal suggests wont get into the kernel as Linus thinks it is too close to a Microkernel model. Personally I would hope there are good technical reasons FUSE has not been accepted rather than simply saying all file systems should be implemented entirely in kernel space (after all do we really want GMailFS in kernel space?) Of course Linus is only human (unlike Alan (more Linus quotes)) and has been known to allow code into the kernel in a strange manner in the past. Such as when Dave Miller got the bottom halves stuff in a few years ago. (anyone got a link to something about this I wonder?)
