YouTube & Hardware

On the "flash is just a bad format" thread:  I do note that my DirecTV DVR 
manages to play YouTube videos full screen without stalling and jerking.  
Obviously dedicated decoding hardware, the CPU is pretty low-power.

Re: YouTube & Hardware

IIRC, YouTube stores it's videos in H.264 and the Flash player is just
one front end.  I strongly suspect that your DVR isn't using Flash.
It probably has a hardware H.264 decoder.  It's what the iPad does.

Re: YouTube & Hardware

For what it's worth, you can opt-in to an HTML5 beta version of
YouTube (I assume it's using WebM encoding) if your browser supports
the technology.

http://www.youtube.com/html5

From my limited playing around with it, the performance isn't much
better (if any) on my PC than the 64-bit Flash player.  I'm guessing
it's more my inability to figure out how to get decent graphics
drivers configured (if they even exist) more so than the technology
itself.

For file transfers, you might be able to use kermit or zmodem.  They have 
packet retransmission capabilities designed to work over links with losses 
and lag.  iirc Kermit was designed to be used over satellite links where lag 
was the bigger problem and zmodem was developed to cope with dropped packets.

Getting the remote system to speak one of those protocols will be the 
challenge.

There's xmodem s/w for unix out there in the wild with my name on it.

cluster storage use case


I'm working with loopback-mounted image files on a CIFS server. I wonder if I could format those images GFS and then have better simultaneous access for them. That might be easier than creating a NFS server for the purpose, only I don't think it's a supported use case.

Thoughts?

Greater Kansas City cluster?


With google fiber on the horizon, one of the opportunities is establishing city-wide clustering of various kinds.

Who would like to meet and discuss the potential for creating cluster-based businesses, using the tipjar LLC accounting platform to track both used and provided services?

Please reply off-list.

Re: Greater Kansas City cluster?

Or better a public distributed off-site backup, where you can backup as much as you provide.

Re: Greater Kansas City cluster?

More like you can back up a specified fraction of what you provide.  A scheme like this requires extra redundancy to make up for potential downtime of some nodes at any given moment.  It also could use pre-transmission encryption so that the people holding backups could honestly say they don't have the decryption keys. 


[Linguistic nit-pick:  When used as a phrasal verb, "back up" is two words, but when used as a noun or adjective, "backup" is one word.  You "back up" data, producing a "backup copy", or simply a "backup".]

Re: KCLUG Digest, Vol 84, Issue 4

There's already several cluster filesystems, but most aren't structured for privacy from everyone else. http://en.wikipedia.org/wiki/Distributed_file_system

It would also be nice to be able to specify a distribution count, so really important files get more copies.
