There was the following passage in the New Yorker's (August 27) article titled, “A scandal at the C.I.A. May be.” :


  In January I (David Shafer, novelist) filed a Freedom of Information Act request with the C.I.A., asking for any information relating to my grandfather and Thomas Whittemore and the events of June 1950. They took two months to give me bupkes. But to give me bupkes, they were required to invoke a FOIA exemption, and the exemption that C.I.A. involved were (b)(3), which means the records are protected by another federal statute, and (b)(1) ---


Though I was unable to find the definition of “bupke” in OED (10th ed.), OALD (2000), and Collins Cobuild (4th ed.) at hand, I happened to find its definition at bageldrive.com, which says “bupke” is;


  A mini-bagel deliciously baked to perfection with fully functional USB 2.0 flash memory and a shmeer. It’s the world’s first electronic bagel. The Bagel Drive is ideal for storing files, photos, video, music and all of your digital tchochkes.　The site also shows photos of USB attached to plastic bagel models.


What does bupke mean? Is it a flash memory in a bagel shape as described in bagldrive com.? Does it pass as the generic term of flash memory? 

Beside, I wonder why CIA takes bother of using such a funky shape of all flash memories to provide data to the requester.
