236: The Concept of Delayed Gratification (Repeat)
Play episode · 1 hr 10 min

Roger Linn (@roger_linn) gave us new ideas about musical instruments, detailing how wonderful expressive control, 3D buttons, and keyscanning can be.

Roger’s company is Roger Linn Design. We talked extensively about the LinnStrument, some about the AdrenaLinn for guitar, and only a little bit about the analog drum machine Tempest.

A key matrix circuit is a popular way to handle a large number of buttons but it falls prey to n-key rollover. Roger adds force sense resistors to this (FSR example at Sparkfun).

If you have an idea for an instrument, Roger has already written his response to your request for a prototype. Roger gave a keynote address at ADC '16 about the LinnStrument, including showing the sounds it can make.

OHMI Trust is the one handed musical instrument society enabling music making for everyone.

 

Roger mentioned some other expressive instruments including:

CEP007 – Combining Art and Technology with Sarah Petkus
Sarah's personal site (shown throughout the video) She Bon is a project exploring human sexuality and helping people discuss it in a more healthy way. It has multiple smaller projects we discussed HotSpot PulsePack Sarah shows the hardware to different groups. The hackers at DEFCON are different than the artists at Ars Electronica Sarah entered the project into the Hackaday Prize and also gave a talk at the Hackaday Superconference about it. Comparing artists and jackets, the former usually want to show completely finished work, instead of something that might be in progress. This means artist sometimes outsource the technical work. Sarah likes doing both. "You learn the most when you do it all, when you have the control" Howdo we get more art people to be technical? How do we get more crossover? "I made this!" Noodlefeet is Sarah's robotic offspring. she has been creating an upgrading him for over 5 years. The Noodlefeet playlist on Sarah's Youtube channel Rebuilding Noodle to make him more sturdy, especially while walking. Ship of Theseus The Noodle brain uses a Jetson Nano for classifying images. See the 'mother of machine' site for more info. End Effectors "The tasting channel" Sarah got started in 3D using SketchUp, as did Chris. She learned parametric modeling via Fusion360 went on a deadline.

Season Four Wrap: Whose Design Is It Anyway? with Swadia, Windholtz, Rezentes, and Keathley
To close off this season and conclude our deep dive into system and application architecture, today’s episode is a special panel discussion on a topic that has provoked a mix of answers that range from the controversial to the philosophical — “What does domain-driven design mean to you?” For the final word on this subject, we welcome back software developers Chris Keathley, Japa Swadia, Mark Windholtz, and Miki Rezentes. Our first hot take comes from Miki, who shares her thoughts about how domain-driven design developed because the tech industry undervalues communication. Following this, Mark and Japa discuss how domain-driven design gives developers a context for what they create while informing how you code using Elixir. We then touch on whether domain-driven design makes it easier or more difficult to change your code and how communication is valued within a business context. We explore key domain-driven design concepts, including the role of bounded contexts, and how this design ethos can help you appeal to stakeholders such as product managers. After Miki highlights the reasons why communication should be seen as a vital tech skill, each guest provides their final thoughts on domain-driven design. Tune in for this season’s insightful finale and find out which of today’s guests is the winner of “Whose Design Is It Anyway?” Key Points From This Episode: Introducing guests Chris Keathley, Japa Swadia, Mark Windholtz, and Miki Rezentes. Hear what domain-driven design means for each guest. Miki shares her hot take that domain-driven design is “nothing new under the sun.” Why the essence of domain-driven design is about listening. How domain-driven design can inform your Elixir architecture. Mapping your system and developing names for your bounded contexts. Domain-driven design trade-offs and how it can lead to a loss of productivity. The idea that domain-driven design has developed because the tech industry undervalues communication. Why communication should be valued — bad communication costs money. How tech companies are generally aligned with the goals of domain-driven design. Why Mark is so delighted to be working with Elixir and domain-driven design. The link between domain-driven design and developing better products. Exploring how bounded contexts allow teams to create solutions to unique problems. Seeing communication as a tech skill that should be learned early in your career. Our guests share their final thoughts on domain-driven design.
