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.

349: Open Down to the Transistor
Drew Fustini (@pdp7) spoke with us about building Linux, RISC-V cores, and many other things. Links, so many links! Drew is a board member of the BeagleBoard.org Foundation and of the Open Source Hardware Association (OSHWA.org). He is an open source hardware designer at OSHPark (he recommends their blog!). He writes a monthly column for Hackspace Magazine, for example The Rise of the FPGA in Issue 26 and  Intro to RISC-V.  Yocto is a tool to help build a Linux distribution specific to your board and application! Bootlin offers free training material for Yocto and OpenEmbedded (as well as many other things such as Embedded Linux and Linux kernel development). Or there is a video: Buildroot vs Yocto: Differences for Your Daily Job - Luca Ceresoli at Embedded Linux Conference. Or look at Embedded Apprentice Linux Engineer (e-ale.org). Or maybe another video: “Yocto Project Dev Day Virtual 2020 #3: Yocto Project Kernel Lab, Hands-On, Part 1” by Trevor Woerner. RISC-V is an open source processor core. Well, cores. But you can try them out in hardware even if you don’t want to play with an FPGA. The SiSpeed Longan Nano has a GigaDevices microcontroller dev board (with an OLED on board!, more info). Did you know you can run Linux on RISC-V? The cheapest method is emulation and Renode is brilliant for that. Here is Drew using it on the train (twitter). Sipeed boards with Kendryte K210 start at only $13 and can even run Linux (tutorial). There are also affordable open hardware FPGA with free software toolchain support like the ICE40 based Icebreaker and Fomu. For a bit more money, the bigger ECP5 can run Linux. Or look at Greg Davill’s wonderful Orange Crab. For a lot more money but on silicon, the Icicle with Microchip PolarFire SoC is aimed at corporate use. Or you can produce your own physical chips. For free (for a limited time). See the talk from Tim Ansell - Skywater PDK: Fully open source manufacturable PDK for a 130nm process Drew attends a lot of conferences, here are highlights from the past: * OHS 2020 wrist badge  * OHS 2018 epaper badge  * ELC-2018 EALE Buildroot - Thomas Petazzoni  * ELC-2018 EALE Bitbake YP - Behan Webster * Linux on RISC-V with open hardware and open FPGA tools * Sldies for Embedded Linux Conference * Video from FOSS North * Linaro Connect BoF: gpio and pinctrl in Linux kernel (Slides) * RISC-V: How an open ISA benefits hardware security (Slides) * (Hardwear.io video)   Here are some future conferences he’s planning to attend: * Embedded Linux Conference Europe ($50) October 26-29, 2020 (Virtual) * Yocto Project Virtual Summit ($40) October 29-30, 2020 (Virtual) * Open Hardware Summit March 13, 2020

The unreasonable effectiveness of synthetic data with Daeil Kim
Supercharging computer vision model performance by generating years of training data in minutes. Daeil Kim is the co-founder and CEO of AI.Reverie(https://aireverie.com/), a startup that specializes in creating high quality synthetic training data for computer vision algorithms. Before that, he was a senior data scientist at the New York Times. And before that he got his PhD in computer science from Brown University, focusing on machine learning and Bayesian statistics. He's going to talk about tools that will advance machine learning progress, and he's going to talk about synthetic data. https://twitter.com/daeil Topics covered: 0:00 Diversifying content 0:23 Intro+bio 1:00 From liberal arts to synthetic data 8:48 What is synthetic data? 11:24 Real world examples of synthetic data 16:16 Understanding performance gains using synthetic data 21:32 The future of Synthetic data and AI.Reverie 23:21 The composition of people at AI.reverie and ML 28:28 The evolution of ML tools and systems that Daeil uses 33:16 Most underrated aspect of ML and common misconceptions 34:42 Biggest challenge in making synthetic data work in the real world Visit our podcasts homepage for transcripts and more episodes! www.wandb.com/podcast Get our podcast on Apple, Spotify, and Google! Apple Podcasts: bit.ly/2WdrUvI Spotify: bit.ly/2SqtadF Google:tiny.cc/GD_Google We started Weights and Biases to build tools for Machine Learning practitioners because we care a lot about the impact that Machine Learning can have in the world and we love working in the trenches with the people building these models. One of the most fun things about these building tools has been the conversations with these ML practitioners and learning about the interesting things they’re working on. This process has been so fun that we wanted to open it up to the world in the form of our new podcast called Gradient Dissent. We hope you have as much fun listening to it as we had making it! Join our bi-weekly virtual salon and listen to industry leaders and researchers in machine learning share their research: tiny.cc/wb-salon Join our community of ML practitioners where we host AMA's, share interesting projects and meet other people working in Deep Learning: bit.ly/wb-slack Our gallery features curated machine learning reports by researchers exploring deep learning techniques, Kagglers showcasing winning models, and industry leaders sharing best practices. app.wandb.ai/gallery
