prl{*} and the "hidden" parallels command set

I'm a CLI freak - there I said it. Today I was futzing with clovr.org (very cool informatics cluster system) and looking at spinning up their instance under Parallels 6.0. As with all things I got a little distracted, and started to look at the SDK for Parallels. There is an amazing and monster programing guide here - lots of ideas to be had here, more at the end of this post!

pNFS v4.1: is bigger actually better? - a short study in big fat RFCs

So I heard a fascinating statistic today that pNFS was the largest RFC ever devised. I've been watching the growth of pNFS for six or so years now - sure is a fascinating protocol, in research computing we all want it to win, and win big.

If you want to know more about pNFS here is a really nice 10,000ft overview video: courtesy of our friend Brent Welch over at Panasas.

Anyway, so I thought I'd check into this "largest RFC ever" comment thing. If you think about it for about ten seconds, any "this is the biggest ever" is a pretty sketchy claim to fame no matter what you are talking about. For filesystems protocol specs, I'm thinking that you certainly don't ever actually want to win that contest!. So I started to wonder what the largest RFC of all time actually is and if there is any correlation to other "big" rfcs.

ditch that high price vpn with sshuttle and an 'ology...

Stumbled across this one today: https://github.com/apenwarr/sshuttle#readme

In the style of Maureen Lipman who famously said in her British Telecom advert:

"you got an 'ology' you're a scientist!".

And there is no need to take the decorations off the cake either!

So if you got port 22? You've got a VPN!

DIY $ / TB and RC playing catch up quick!

I had the opportunity to speak on the phone with Gleb Budman back in early 2010 about how we could best use his building blocks to support science with my RC team. We both decided we were not quite ready and would postpone any grand ideas of pushing 2PB of our data to backblaze.com at least for a little while... that reminds me I need to catch up with Gleb again :-)
