The Solaris 10 Zones Contest running on an Ultra 10 is well on its way. Keep in mind this sucker only has 512MB of RAM! (Can you tell I copy/pasted that from yesterday's blog?)

If I have read my contents blog comments right, the highest guess was 81 1/2 by Lasse Koskela. Congrats, Lasse, your the winner!! 86 zones and I stopped (could have gotten more if I pkgrm'd like crazy). 81 1/2 was a pretty good guess. Email me your address and I'll send you the shirt.

The Ultra 10 is still chugging along at 86 zones. I stopped it there simply because I am out of disk space. With the OEM bits distribution installed (that means ALL the Solaris bits) and an over-allocated SWAP, I am stuck unless I remove packages and/or wipe the hard drive and allocate less swap. Too much backwards work while I want to continue to move forward. The good news is that Solaris on this resource-constrained Ultra 10 has topped everyone's expections at 86 zones.

While the Zones contenst is officially over, the counting is not. I am hooking this baby up to more (external) storage (more on that next week). I hope to find another 512MB of RAM. Anyone at Sun have 512MB I can borrow? It should be quite entertaining.

There are some questions in various blog entries where people are asking some questions about swapping, resource consumption, etc. I am out of time today but here is a quick look at the Ultra 10:

Wow. The U10 is starting to hurt. Look at all of that paging from just ... sitting idle.Notice the Scan Rate of 4743? Holy hanging on by a thread, batman, is that an anomoly? No, Robin, it's kicking off vmstat (SWAG on my part)

I just added a photo of myself to the blog. Don't I look spiffy after a new haircut? No comment necessary ... :)

On numerous occasions, I have been told I look like Linus Torvalds (pictured on the right). I even had Marc Fluery (JBoss) speaking at the LAJUG say the similarity was uncanny. At first, he said joking[heavily paraphrased], that he should bow down and say he's not worthy. I didn't try to stop him, of course, but he quickly realized it wasn't Linus when he saw the Sun logo'd shirt :)

At the OCJUG in the elavator up to the meeting room, after 15 seconds of staring they had to simply come out and ask.

The litmus test. In preparing this blog, I googled "torvalds.jpg" with my 4 year old daughter on my lap and even she asked "Daddy, is that you?". OK, after that I had to ask my wife in a jealous manner if she had ever been anywhere near Linus ...

A sales rep (heathen non-blogging type) posted a magazine page on a locker wall (we don't have dedicated offices, only lockers). Something like "Clingan?" written next to a picture of Linus.

My opinion? In some pictures I do look like Linus .. ahem ... Linus looks like me. In some we do not look alike. It's hard to match up any picture that I have with a picture of Linus in the same position at the same age. It's uncanny that we both seem to be gaining weight at exactly the same rate, though.
