0. Operational blog posts

   No operational issues.  Also no new blog posts...

1. Highlights from WLCG workshop - https://indico.cern.ch/event/555063/sessions/207257/

   * In other news!  CMS keen on remote access (aka AAA).  What does "smart placement" mean?
   * Greater visibility for the xroot cache at SLAC...
   * EOS using erasure code, but can be implemented on CEPH but doesn't necessarily use CEPHs, but its own.  If that makes sense.
     - Apropos, Sam's poster also looking at reconstruction of data
     - EC needed by EOS not for resiliency purposes as much as speed of recalling data.
   * StoRM has WebDAV from INDIGO datacloud implemented, i.e. the same kind of Macaroon (= fancy cookie) as dCache.
     - Presumably this includes the LDAP facade.
   * DPM also included the recent features except didn't mention distributed DPM, which seems to be less popular.
   * Note the distinction between "old protocols" (SRM), "good protocols" (http, xroot), and "new protocols" (S3)

   As an aside, there were proposals for encrypting or more generally m-of-n'ing blocks so no single datacentre could
   reconstisute the data - Sam mentioned the "least authority filesystem"; Jens thought of the m-of-n - since LAFS advertise
   S4 it is probably the same thing (ie S4 being m-of-n.)  Obviously this is totally overkill for our security requirements,
   and users would in fact not like not being able to read the data - while they may like the features of the more complex
   software, they would like to be able to recover the data even if the complex software fails...

   And we can start looking at the CHEP stuff, too, with Janusz representing MICE; with LHCb, Marcus' talk, etc.
   Ice cube - data transfer catalogue reimplemented...!?

2. A few loose ends we need to tie up, if pos

   No submissions reported yet for cloud workshop.

3. Also the usual quarter stuff

   No suggestions (yet) for the next todo items (ticklist for Pete's report), but the DPM workshop in Nov would
   be an obvious entry.  WLCG is already counted in a separate table.

4. AOB

   NOB

.... a macaroon is a fancy cookie :-)
