SUMMARY:🔁 Cassette Tape Loop Workshop
DESCRIPTION:Learn to make physical audio loops with used cassette tapes! No experience needed. \nFor the workshop we’ll be using cassettes with screws in the corners\, which are easier to take apart but less common than the ones fastened with glue. We’ll have regular cassette tapes for $1 each if you want to keep experimenting at home. \nRegister:\n\n  \nStep 1: Choose a used cassette tape. \nStep 2: Rewind the tape and record a minute or two of music\, your voice\, and/or percussion sounds. Then eject it. \nStep 3: At the bottom of the cassette there’s a small area where the magnetic tape is exposed. Use a paperclip or pencil to pull the tape out an inch or so\, then cut the tape with scissors. The recording you just made is now on the smaller spool\, while the bigger spool contains whatever was originally on the tape. \nStep 4: If you’re using a glued-together cassette (no screws)\, carefully separate the plastic shells using a pry tool. Ask the instructor for help. If you have a cassette with screws\, use a tiny screwdriver to unscrew all four corners. \nStep 5: Print and assemble tape loop template. (Link) \nStep 6: Cut several 9″–10″ lengths of cassette tape. \nStep 7: Wrap a length of tape around your template tube and attach the ends with a tiny drop of superglue. To avoid using too much glue\, you may want to apply it using the tip of a needle. \nStep 8: Put your loop into a cassette shell and screw the corners together. \nStep 9: Load the tape into a tape player and press play!

SUMMARY:👁️ Intelligence History Reading Group: 'Agents of Subversion' by John P. Delury
DESCRIPTION:For the first installment of the Intelligence History Reading Group\, we’re reading Agents of Subversion: The Fate of the CIA’s Covert War in China by John P. Delury (2022). We’ll discuss parts 1 & 2 on Weds\, June 18th and parts 3 & 4 on Weds\, July 16th. We’ll meet in person at Iffy Books (404 S. 20th St.\, PHL) from 7:00 p.m. – 8:30 p.m. Thanks to Jack Poulson for starting the group! \n\n\n—————– \nAgents of Subversion reconstructs the remarkable story of a botched mission into Manchuria\, showing how it fit into a wider CIA campaign against Communist China and highlighting the intensity―and futility―of clandestine operations to overthrow Mao.  \nIn the winter of 1952\, at the height of the Korean War\, the CIA flew a covert mission into China to pick up an agent. Trained on a remote Pacific island\, the agent belonged to an obscure anti-communist group known as the Third Force based out of Hong Kong. The exfiltration would fail disastrously\, and one of the Americans on the mission\, a recent Yale graduate named John T. Downey\, ended up a prisoner of Mao Zedong’s government for the next twenty years.  \nUnraveling the truth behind decades of Cold War intrigue\, John Delury documents the damage that this hidden foreign policy did to American political life. The US government kept the public in the dark about decades of covert activity directed against China\, while Downey languished in a Beijing prison and his mother lobbied desperately for his release.  \nMining little-known Chinese sources\, Delury sheds new light on Mao’s campaigns to eliminate counterrevolutionaries and how the chairman of the Chinese Communist Party used captive spies in diplomacy with the West. Agents of Subversion is an innovative work of transnational history\, and it demonstrates both how the Chinese Communist regime used the fear of special agents to tighten its grip on society and why intellectuals in Cold War America presciently worried that subversion abroad could lead to repression at home. \n\n🎧 Get the audiobook on Libro.fm
