PLUG Central will be meeting on Wednesday, July 3 at USP in
Philadelphia, beginning at 7pm. Directions to the meeting location at
the University of the Sciences in Philadelphia can be found at the end
of this email.

This month, PLUG welcomes back Elizabeth J. Joseph. Lyz will be giving
a talk entitled "Linux on Mainframes: Past, present, and future".

  The discourse around where to host your Linux-based infrastructure
  tends to center around whether you should use the cloud or your own
  on-premises x86 hardware, but mainframes are rarely discussed. In
  this talk we'll have a look at how VM technology that got its start
  in the 1970s allowed Linux to be run on the mainframe by a group of
  hobbyists in the late 1990s. Then on to how it was swiftly noticed
  by IBM and development continued for the polished product line of
  mainframes that exclusively run Linux (officially RHEL, SLE, and
  Ubuntu) today.

  For the security-conscious, encryption technology built into the
  processor and on additional PCIe cryptography cards is accessible in
  Linux on the mainframe with your standard OpenSSL libraries,
  allowing for end-to-end encryption of data at rest and in flight
  that doesn't burn all of your regular processor resources.
  Enterprise-grade hardware that also has built-in redundancy reduces
  the need for management of a fleet of x86 servers, and the entry
  level Linux-only mainframes today even fit into a 19" rack space in
  the datacenter.

  Looking at the future, it's likely that even more pervasive
  encryption and reductions power consumption will be high on the list
  of requirements, and running Linux on a mainframe can help with
  those too!

The meeting will be held at our usual location:

  University of the Sciences in Philadelphia (USP)
  Griffith Hall (Room "C" or "A", look for the signs)
  600 South 43rd Street
  Philadelphia, PA 19104-4495

USP is located in University City. Driving directions are
available at http://www.phillylinux.org/locations/usp.html, or
http://www.usip.edu/directions, both of which have an aerial view
of the campus buildings. USP is also easily accessible by public
transportation.

For those attending PLUG Central, if you arrive and the doors are
locked you can call UCS's public safety number at 215.895.1117 and
they will radio personnel in the guard booth or someone else to unlock
the door.  If you are asked who is sponsoring the meeting you can say
"Zhiwei Liu" in the Chemistry department.

There will be an open Question & Answer session at 7PM, prior to the
main presentation at 8PM. This is an open meeting; all are welcome and
encouraged to attend.

Usually, a number of members get together after the meeting at a
nearby restaurant for food and perhaps a beer or two. Come join the
camaraderie!
