I suppose that by ensuring that almost every female gamer I know will think that the Vita is targeted to young men with the mental stature of Beavis and Butthead, you've advanced the status of women in gaming by keeping them away from a truly lame platform. Kudos to Sony for advancing the status of women in the gaming community.

This is great, but long, so If you're interested in how flashpool works I've selected some start and stop times for the most relevant pieces.

1:273:43  of explanation of how NetApp cache based virtual storage tiering works vs traditional auto-tiering approaches, and why it is superior
13:13 - 15:28 - Intro to Flashpool
15:2818:21 – Long kind of rambly discussion about flash pool about random overwrite caching
18:2120:30 – Good technical explanation of read and write caching in flashpool
20:30 –  Discussion around how we track the age of the block in the cache for ageing (interesting but technically deep)
23:20 -23:47  More Discussion about interactions with snapshots and checkpointing to hard disk
23:48 -24:30  Example of cost reductions for the same performance
24:31 - 25:50   - Discussion on how much cache you can add to a system (numbers are now bigger since ONTAP 8.2.1 was released)
25:50 - 27:05  Example of performance improvements for the same expenditure
27:05 - 29:30 - Summary of when to use flashpool vs flashcache.

This video was produced a little under a year ago, and things have progressed, and my personal feeling is that for greenfield implementations following best practices for Clustered Data ONTAP from 8.2.1 onwards, the non disruptive addition of additional capacity, plus larger sizes and the falling price of SSD makes flashpool the default choice for Automated Storage Tiering, with FlashCache reserved for special use cases.

If you've got the time, the section that follows on FlashAccel is also good, and is now even better with recent updates to the software.

My first Computerworld blog got published today ... http://blogs.computerworld.com/cloud-storage/22895/designing-cloud-storage-ditch-lun-cfbdcw. I'm feeling somewhat chuffed.
I’m always surprised that so many people still want to build their private and public cloud on logical units, served out by Fibre Channel SANs. From my point of view, we should have ditched the LUN years ago: Storage management problems at scale created by the LUN presents some of the toughest IT challenges, and those problems are a direct result of the massive success of virtualization.

'm tired of being lied to. I'm tired of broken election promises. I'm tired of deceptive corporate marketing. I'm tired of the everyday hypocrisy that surrounds me every day. But most of all I'm tired of the lies I tell myself. Things will change, things must change ... I will begin with what I can control, I will start with myself. I will hold myself to a higher standard of honesty and I will encourage others to do the same. I will be less tolerant of dishonesty in others even when it benefits me. The truth is precious and trans-formative, it is time we treated it with the respect it deserves. #BeTrue.

I remember reading this a long time ago ... it sets a bar for what "Thought leadership" should look like in the storage industry.
Tape is Dead Disk is Tape Flash is Disk RAM Locality is King. Jim Gray. Microsoft ... 1995 16 Mb NAND flash chips ... Current FLASH disks could do much better

http://kck.st/17BKz3h  ... 3D Robot Turtles ...  some things are just too cool to ignore ... or is that just me ?

But seriously, IMHO the ability think in structured programmatic ways is not just about the new literacy, or the ability to control a technology that is indistinguishable from magic, its about being able to reduce your problems to small manageable chunks, and think a few moves ahead.

Now if someone has some good suggestions for thinking holistically for kids let me know, until then I'm breaking out the easel,  paintbrushes and modelling clay.
Robot Turtles is the the most-backed board game in Kickstarter history. It sneakily teaches programming fundamentals to kids ages 3+.

If I'm going to be a pioneer, may as well do it in unexplored terrirory.
Dart is a new platform for building structured web apps for modern browsers. It includes a language, a VM, libraries, tools, and a compiler to JavaScript. Try Dart today!
