SUMMARY:⚙️ Neo-Luddite Reading Group: 'The Technological Society' by Jacques Ellul (pt. 1 of 3)
DESCRIPTION:We’re reading the first 1/3 of the book for this month! Check out the full schedule at victorgom.es/neoluddite \n➡️ Virtual Meetup Link\nDiscord: Email neoluddite@victorgom.es for an invite! \nIf you’re joining for the first time\, I’d suggest you read this before anything else for brief context: What the Luddites Really Fought Against by Richard Conniff.The only expectation is that you read the chapter(s) of the book that’s listed for that meeting. You’re still welcome to participate if you haven’t done the readings as long as you are mindful. For each chapter\, I’ve also noted some optional readings for context\, so I’d suggest checking those out rather than reading ahead in the book. And remember\, if you ever find yourself struggling with any of the readings or concepts\, reach out! Either directly to me over email or to the entire group over discord.

SUMMARY:🔊 DJ Basixxx with Mixxx
DESCRIPTION:If you’re curious about DJing but don’t have money to drop on equipment\, this workshop is for you! You’ll learn to use Mixxx\, a free and open source DJ program for macOS\, Windows\, and Linux. Mixxx supports a wide range of DJ controller hardware\, but to make it more accessible we’re using regular QWERTY keyboards with stickers on the important keys. We’ll teach you to find tracks on the web\, load them into Mixxx\, and get started with beatmatching. It’s easier then you think! \nYou’ll need to bring your own laptop and headphones for this workshop. We also recommend bringing a separate USB keyboard if you have one\, ideally with a row of function keys (F1\, F2\, F3\, etc.). If you have an external audio interface\, you’re welcome to bring that too. \nThe DJ controller sticker sheets we’re using are available on our online store. Or print your own (4″ x 4″) on sticker paper! \n➡️ Workshop instructions \nRegister:\nPlease enable JavaScript in your browser to complete this form.Name/pseudonym:Email address:EmailConfirm EmailBuy a sticker sheet (optional)DJ controller keyboard stickers - $2.70(price includes tax)Instructor donation:$0 / donate later$5$10$15$20$25(suggested $5–$20)Credit card info: *CardName on CardComments or questions?Submit  \n \n \nCircuitPython code for turning a Pi Pico board into a USB keyboard

SUMMARY:🔊 DJ Basixxx with Mixxx
DESCRIPTION:If you’re curious about DJing but don’t have money to drop on equipment\, this workshop is for you! You’ll learn to use Mixxx\, a free and open source DJ program for macOS\, Windows\, and Linux. Mixxx supports a wide range of DJ controller hardware\, but to make it more accessible we’re using regular QWERTY keyboards with stickers on the important keys. We’ll teach you to find tracks on the web\, load them into Mixxx\, and get started with beatmatching. It’s easier then you think! \nYou’ll need to bring your own laptop and headphones for this workshop. We also recommend bringing a separate USB keyboard if you have one\, ideally with a row of function keys (F1\, F2\, F3\, etc.). If you have an external audio interface\, you’re welcome to bring that too. \nThe DJ controller sticker sheets we’re using are available on our online store. Or print your own (4″ x 4″) on sticker paper! \n➡️ Workshop instructions \nRegister:\nPlease enable JavaScript in your browser to complete this form.Name/pseudonym:Email address:EmailConfirm EmailBuy a sticker sheet (optional)DJ controller keyboard stickers - $2.70(price includes tax)Instructor donation:$0 / donate later$5$10$15$20$25(suggested $5–$20)Credit card info: *CardName on CardComments or questions?Submit  \n \n \nCircuitPython code for turning a Pi Pico board into a USB keyboard
