Because of my position as Executive Producer and host of The Untold Stories of Open Source, I frequently get asked, “What podcasts do you listen to when you’re not producing your own.” Interesting question. However, my personal preference, This American Life, is more about how they create their shows, how they use sound and music to supplement the narration, and just in general, how Ira Glass does what he does. Only podcast geeks would be interested in that, so I reached out to my friends in the tech industry to ask them what THEY listen to. The most surprising thing I learned was people professing to not listen to podcasts. “I don’t listen to podcasts, but if I had to choose one…”, kept popping up. The second thing was people in the industry need a break and use podcasts to escape from the mayhem of their day. I like the way Jennifer says it best, “Since much of my role is getting developers on board with security actions, I gravitate toward more psychology based podcasts – Adam Grant’s is amazing (it’s called WorkLife).” Now that I think of it, same here. This American Life. Revisionist History. Radio Lab. The Moth. You get the picture. Escaping from the mayhem of the day. Without further digression, here are the podcasts recommended by the people I trust, no particular order. No favoritism. The Haunted Hacker Hosted by Mike Jones and Mike LeBlanc Mike Jones and Mike LeBlanc built the H4unt3d Hacker podcast and group from a really grass roots point of view. The idea was spawned over a glass of bourbon on the top of a mountain. The group consists of members from around the globe and from various walks of life, religions, backgrounds and is all inclusive. They pride themselves in giving back and helping people understand the cybersecurity industry and navigate through the various challenges one faces when they decide cybersecurity is where they belong. “I think he strikes a great balance between newbie/expert, current events and all purpose security and it has a nice vibe” – Alan Shimel, CEO, Founder, TechStrong Group Risky Biz Security Podcast

ONE Summit Agenda is now live! This post originally appeared on LF Networking’s blog. The author, Heather Kirksey, is VP Community & Ecosystem. ONE Summit is the Linux Foundation Networking event that focuses on the networking and automation ecosystem that is transforming public and private sector innovation across 5G network edge, and cloud native solutions. Our family of open source projects address every layer of infrastructure needs from the user edge to the cloud/core. Attend ONE Summit to get the scoop on hot topics for 2022! Today LF Networking announced our schedule for ONE Summit, and I have to say that I’m extraordinarily excited. I’m excited because it means we’re growing closer to returning to meeting in-person, but more importantly I was blown away by the quality of our speaking submissions. Before I talk more about the schedule itself, I want to say that this quality is all down to you: You sent us a large number of thoughtful, interesting, and innovative ideas; You did the work that underpins the ideas; You did the work to write them up and submit them. The insight, lived experience, and future-looking thought processes humbled me with its breadth and depth. You reminded me why I love this ecosystem and the creativity within open source. We’ve all been through a tough couple of years, but we’re still here innovating, deploying, and doing work that improves the world. A huge shout out to everyone across every company, community, and project that made the job of choosing the final roster just so difficult. Now onto the content itself. As you’ve probably heard, we’ve got 5 tracks: Industry 4.0, Security and Privacy, The New Networking Stack, Operationalizing Deployment, and Emerging Technologies and Business Models: “Industry 4.0” looks at the confluence of edge and networking technologies that enable technology to uniquely improve our interactions with the physical world, whether that’s agriculture, manufacturing, robotics, or our homes. We’ve got a great line-up focused both on use cases and the technologies that enable them. “Security and Privacy” are the most important issues with which we as global citizens and we as an ecosystem struggle. Far from being an afterthought, security is front and center as we look at zero-trust and vulnerability management, and which technologies and policies best serve enterprises and consumers. Technology is always front and center for open source groups and our “New Networking Stack” track dives deep into the technologies and components we will all use as we build the infrastructure of the future. In this track we have a number of experts sharing their best practices, as well as ideas for forward-looking usages. In our “Operationalizing Deployment” track, we learn from the lived experience of those taking ideas and turning them into workable reality. We ask questions like,  How do you bridge cultural divides? How do you introduce and truly leverage DevOps? How do you integrate compliance and reference architectures? How do you not only deploy but bring in Operations? How do you automate and how to you use tools to accomplish digital transformation in our ecosystem(s)? Not just content focusing only on today’s challenges and success, we look ahead with “Emerging Technologies and Business Models.” Intent, Metaverse, MASE, Scaling today’s innovation to be tomorrow’s operations, new takes on APIs – these are the concepts that will shape us in the next 5-10 years; we  talk about how we start approaching and understanding them? Every talk that made it into this program has unique and valuable insight, and I’m so proud to be part of the communities that proposed them. I’m also honored to have worked with one of the best Programming Committees in open source events ever. These folks took so much time and care to provide both quantitative and qualitative input that helped shape this agenda. Please be sure to thank them for their time because they worked hard to take the heart of this event to the next level. If you want to be in the room and in the hallway with these great speakers, there is only ONE place to be. Early bird registration ends soon, so don’t miss out and register now! And please don’t forget to sponsor. Creating a space for all this content does cost money, and we can’t do it without our wonderful sponsors. If you’re still on the fence, please consider how amazing these sessions are and the attendee conservations they will spark. We may not be the biggest conference out there, but we are the most focused on decision makers and end users and the supply chains that enable them. You won’t find a more engaged and thoughtful audience anywhere else.

The post LFPH Tackles the Next Frontier in Open Source Health Technology: The Rise of Digital Twins appeared first on Linux Foundation.

This post originally appeared on the LF Pubic Health’s blog. The author, Jim St. Clair, is the Executive Director. With the Digital Twin Consortium, Academic Medical Centers and other LF projects, Linux Foundation Public Health addresses open software for next generation modeling Among the many challenges in our global healthcare delivery landscape, digital health plays an increasingly important role on almost a daily basis, from personal medical devices, to wearables, to new clinical technology and data exchanges. Beyond direct patient care, digital health also applies to diagnostics, drug effectiveness, and treatment delivery. These use cases are being driven by rapid growth in data modeling, artificial intelligence (AI)/machine learning (ML), and data visualization. Given the rapid digitalization of healthcare delivery, emerging digital twin technology is considered the next system that will advance further efforts in medical discoveries and improve clinical and public health outcomes. What is a Digital Twin? Put simply, a digital twin is a digital replica or “twin” of a physical object, process, or service. It is a virtual model (a compilation of data plus algorithms) that can dynamically pair the physical and digital worlds. The ultimate goal for digital twins, such as in manufacturing, is to iteratively model, test, and optimize a physical object in the virtual space until that model meets expected performance, at which point it is then ready to be built or enhanced (if already built) in the physical world. To create a pairing between the digital world and the real world, a digital twin leverages real time data, such as smart sensor technology, coupled with analytics, and often artificial intelligence (AI) in order to detect and prevent system failures, improve system performance, and explore innovative uses or functional models. As mentioned, developments in smart sensor technologies and wireless networks have pushed forward the applications of the Internet of Things (IoT), and contributed to the practical applications of digital twin technology. Thanks to IoT, cloud computing and real time analytics, digital twins can now be created to collect much more real-world and real-time data from a wide range of sources, and thus can establish and maintain more comprehensive simulations of physical entities, their functionality, and changes they undergo over time. Digital Twins in Healthcare While the application of digital twins in healthcare is still very new, there are three general categories for their use: digital twins of a patient/person or a body system; digital twins of an organ or a smaller unit; and digital twins of an organization. Digital twins can simulate the whole human body, as well as a particular body system or body function (e.g., the digestive system). One example of this kind of patient-sized digital twin is the University of Miami’s MLBox system, designed for the measurement of a patient’s “biological, clinical, behavioral and environmental data” to design personalized treatments for sleep issues. Digital twins can also simulate one body organ, part of an organ or system, like the heart, and can even model subcellular (organelle/sub-organelle) functions or functions at the molecular level of interest within a cell. Dassault Systèmes’ Living Heart Project is an example of this kind of digital twin, which is designed to simulate the human heart’s reaction to implantation of cardiovascular devices. Additionally, healthcare institutions (e.g., a hospital) can have their corresponding digital twins, such as Singapore General Hospital. This kind of simulation can be useful when determining environmental risks within institutions, such as the risks of infectious disease transmission. The “Heart” of Health Digital Twins is Open Source – and the LF While digital twins represent a complex and sophisticated new digital model, the building blocks of this technology—like all other software foundations—are best supported by an open-source development and governance model. The Linux Foundation sustains the nexus of open source development that underpins digital twin technology: Linux Foundation Public Health (LFPH) is dedicated to advancing open source software development for digital health applications across the globe. Together with its members, LFPH is developing projects that address public health data infrastructure, improving health equity, advancing cybersecurity, and building multi-stakeholder collaboration for patient engagement and health information exchange. The LF AI and Data Foundation is working to build and support an open artificial intelligence (AI) and data community, and drive open source innovation in the AI and data domains by enabling collaboration and the creation of new opportunities for all the members of the community. LF Edge aims to establish an open, interoperable framework for edge computing independent of hardware, silicon, cloud, or operating system. By bringing together industry leaders, LF Edge will create a common framework for hardware and software standards and best practices critical to sustaining current and future generations of IoT and edge devices. The Open 3D Foundation includes many collaborators working to make an open source, fully-featured, high-fidelity, realtime 3D engine for building games and simulations, such as digital twins, available to every industry. “The Open 3D Foundation, along with its partners and community is helping advance 3D digital twin technology by proving an open source implementation that is completely dynamic with no need to preload the media.” said General manager Royal O’Brien, “This can ensure the smallest customizable footprint possible for any device platform to meet any industry needs.” Additionally, LFPH has established a joint membership with the Digital Twin Consortium, focused on healthcare and life sciences. “Artificial Intelligence (AI), edge computing and digital twins represent the next generation in data transformation and patient engagement,” said Jim St. Clair, Executive Director, “Developing a collaborative relationship with the Digital Twin Consortium will greatly advance the joint efforts of model development and supporting open source components to advance adoption in healthcare through multi-stakeholder collaboration.” LFPH looks forward to supporting, innovating, and driving forward an open-source vision in the critical and growing area of digital twins for healthcare.
