  • OpenOCD snapshot uploaded to Debian experimental

    One of the things I maintain in Debian is OpenOCD. I say maintain, but it’s so far required very little work, as it’s been 3 years since a release (0.10.0). I’ve talked about doing a git snapshot package for some time (I have an email from last DebConf in my inbox about it, and that wasn’t the first time someone had asked), but never got around to it. Spurred on by some moves towards a 0.11.0 release I’ve built a recent snapshot and uploaded it to the experimental suite in Debian.

  • How open standards guide us in a world of change

    As I write this article in my home office in Beaverton, Oregon, a Portland suburb, I'm relying (and reflecting) on years of work that went into standards like TCP/IP, HTTP, NTP, XMPP, SAML, and many others, as well as open source implementations of these standards from organizations such as the Apache Software Foundation. The combination of these standards and technologies is literally saving lives, as many of us are able to work from home while "flattening the curve."

    Nothing has dominated the news more in 2020 than COVID-19. Yet, in the midst of challenging time, I've found opportunities for personal and industrial renewal. By fortunate (some may say unfortunate) timing, I found myself switching roles in the middle of this crisis from helping to build and run Open Source Program Offices (OSPOs) to becoming the executive director at OASIS Open, a standards development organization that is helping bring standards and open source together in practical and productive ways.

    Looking through the many articles on Opensource.com related to standards (and there are quite a few), I went on an interesting journey through the different thought processes—and sometimes biases—that people involved in each community have. What stood out most was this: both standards professionals and open source advocates want the same thing—better technology that we all can rely on.

    As I was transitioning to this new role at OASIS, some colleagues and friends in the open source world that I've been a part of for many years questioned my motivations for making this move. In explaining why I took this job, I reflected on the larger role I think the intersection of standards and open source can play, especially in the current crisis we all face.

  • Q&A: How open source made Kubernetes appealing to enterprise app developers

    A: We are at an interesting inflection point right now with computing. We went from physical hardware to virtual machines to containers and to concepts like serverless computing. And we’re asking questions like, “Can it get even smaller?”

    We’re trying to make the underlying platform more powerful, but less and less visible. So if it’s invisible to developers, do we just stop caring about it?

    But you could make the same argument with Linux, right? If the application is done well, and Linux is doing its job, you shouldn't care about it. It's just running, it’s fast, it’s scalable. Kubernetes probably follows that path more than anything.

  • Inside Red Hat: Its open source heritage means big opportunity in cloud computing

    The open source proposition has been embedded in Red Hat’s roots since the company’s founding in 1993 and has since remained at the core of its guiding principles, with Linux operating system (OS) at the heart of all its innovations. Vendor loyalty and clearly charted paths were the mantras many companies operated on for years, while “digital transformation” was barely on an enterprise’s short-term road map.

    Then a decade ago, cloud adoption surged, creating the impetus to embrace more agile and flexible development models, and open source technologies emerged.

    [...]

    While the topic of COVID-19 did not overtly dominate the discussions or significantly color the overarching Red Hat messaging, it became clear that the ability to pivot rapidly, embrace change and remain flexible will underscore Red Hat’s efforts to successfully promote transformation amid the pandemic. Red Hat’s reputation has historically been predicated on its open and agile approach to development and deployment, long before such attributes were considered valuable, let alone essential.

  • Red Hat: Holding Its Own and Fueling Open Source Innovation

    When IBM acquired Red Hat for $34 billion in 2019, it was considered the industry’s largest software acquisition. The synergy between the two companies led them to become one of the leading hybrid multi-cloud providers globally.

    In most acquisitions, the acquired entity sometimes loses momentum and sheds some of its original luster. This does not seem to be the case with Red Hat.

  • This German town replicated itself in VR to keep its tourism alive

    Nicolai Reith, Head of the Control and Communication department and advisor to the Mayor of Herrenberg, told Cities Today: “You don’t have to make a decision and then see [what happens]; you can see before you make the decision what the effect will be via the digital twin. This makes it easier to make the right decision for our city council, politicians, and citizens.”Herrenberg is already using the digital twin, which incorporates super-computing and technologies typically deployed in advanced aerospace, to visualize city data and citizens’ emotional responses to inform better decision-making.

    There are now plans to develop the emerging area of virtual tourism for the town, which has a population of around 31,000.

    “We have a very beautiful city center so tourists can explore it in a digital way with VR glasses before they come to Herrenberg, which is an interesting benefit for the future,” Reith said.

    The team then added in geographic information system (GIS) data and traffic control systems data to incorporate topography, road geometry , and detailed traffic flows. Using the open-source fluid dynamics code OpenFOAM — which is typically used for modeling fuel injector sprays or airplane aerodynamics —they also created realistic models of the movement of wind and emissions through the city.

  • Cucumber ESP32-S2 Development Board Comes with USB OTG Port, Optional Sensors

    Yesterday, I wrote about LilyGO TTGO ESP32-S2 WiFi IoT board, but one commenter mentioned it missed one of the key features of ESP32-S2 chip: a USB OTG port. While USB OTG is accessible through the header pins, it’s not the most convenient to use.

    I also quickly mentioned Cucumber ESP32-S2 development board in that post, but I did not expand too much since I thought it should only ship within Thailand. But the board does include two USB Type-C ports, one for the usual USB UART connector, and the other for USB OTG, and I found out the board is available worldwide.

  • TTGO ESP32-S2 WiFi IoT Board Comes with Optional MicroSD Card and Battery Support

    All ESP32-S2 boards I’ve seen so far were from Espressif Systems themselves including ESP32-S2-Saola-1 and ESP32-S2-Kaluga-1, but LilyGO TTGO ESP32-S2 is the first third-party board for sale so far.

    The tiny board is somewhat similar to ESP32-S2-Saola-1 board and comes in two versions with a similar form factor, but a completely different pinout and the presence of a MicroSD card socket and a battery connector on one of the boards.

    [...]

    The boards are a bit more different than I expected at first look. Please note that specifications should be seen as preliminary, as there were obvious mistakes such as Bluetooth support (not available for ESP32-S2) which I did not included in the specs above, but there may be others which I missed.

  • Open Source Ventilators Helped by Electronic Design Software

    In the early days of the pandemic, the first major challenge facing nations was a shortage of personal protective equipment (PPE) and ventilators. The former helps safeguard hospital personnel from potential contamination; the latter are necessary to keep the most critically ill patients breathing once the virus attacks their respiratory systems.

    Ventilators are traditionally large and very costly devices; smaller ventilators—known as field emergency ventilators (FEVs) have been used in emergency settings, including combat missions and in Third World nations for decades to help keep patients alive as they await transport to hospitals for intubation.

  • NASA JPL Team Fires up Open Source PPE Respirator Designs

    Does it really take a team of rocket scientists to rapidly engineer a top-notch line of personal protective equipment (PPE) to protect against COVID-19 spread? And then to open source its production designs for the benefit of anyone with access to a 3D printer?

    The answer: not necessarily, but it sure can help.

    That’s the latest good news on the pandemic front from the technology and innovation team at the National Aeronautics and Space Administration’s (NASA) Jet Propulsion Laboratory (JPL).

  • NASA and other innovators work to redesign ventilators for Covid-19 patients

    NASA scientists as well as other innovators are busy developing alternatives to the traditional ventilator being used worldwide to treat severe cases of Covid-19. The movement is in response to growing evidence that in some cases ventilators can cause more harm than good in some patients with low oxygen levels. Statistics tell the story: 80% of patients with the coronavirus die on such machines.

    This comes just a few months since the early days of the coronavirus pandemic, when U.S. healthcare providers said that they needed ventilators to accommodate the flood of new patients, and lots of them. The crisis triggered the Trump administration to activate the Defense Production Act so manufacturers including Ford, GM and GE could start ventilator production to produce these medical devices for the U.S. government.

    To learn more about the project, we spoke with Dawn Foster, Director of Open Source Community Strategy at VMware and member of the CHAOSS governing board. FOSSlife: Please give our readers a bit of background on the CHAOSS project. How did it originate and what are its goals? Dawn Foster: The community was formed as a result of a Birds of a Feather at the Linux Foundation Open Source Leadership Summit in 2017 out of a shared desire to collaborate on ways to measure open source project health. It was officially announced as a Linux Foundation project a few months later at the LF Open Source Summit North America. The idea was to bring together several different analytics tools, like GrimoireLab and cregit, into a coordinated effort while also developing metrics definitions that could be used by any implementation. [...] Dawn Foster: Anyone can participate in the CHAOSS project! I think sometimes people think that CHAOSS is all about software development on the tools we use to gather the metrics, and while that's an important part of what we do, it isn't everything. Most of the time, the working groups are discussing and defining metrics, which is something anyone can do. We collaboratively work together in documents to define metrics to better understand what questions they answer and why they are important in addition to talking about what data you might need to collect. In some cases, like with many of the diversity and inclusion metrics, qualitative measurements are an important element of the metrics definitions. We need people from all backgrounds with different skills to help us define metrics in a way that is useful for a variety of people and organizations. In addition to the metrics, CHAOSS is a fun community of smart and welcoming people, so it's a place where you can enjoy contributing!

  • NVIDIA K8s Device Plugin for Wind River Linux

    The advent of containers has changed the way computational workloads are managed and orchestrated in modern computing environments. Given the paradigm shift towards the microservices, container orchestration has become of critical importance in today’s distributed and cloud systems [1]. Managing edge devices on the scale of hundreds and thousands is an onerous task. Fortunately, orchestrators such as Kubernetes take the complexity out of updates, roll-backs, and more in a platform-agnostic environment. [2]. Orchestrators provide the means to manage heterogeneous edge clusters. It is necessary to not only orchestrate containers but to discover the hardware specialized devices that the containers and orchestrator can leverage. Failing to manage these resources can lead to inefficiency, time drain, concurrency issues, and more.

  • The Rise and Fall of Commercial Smalltalk

    Smalltalk actually had a surge of commercial popularity in the first half of the 1990s but that interest evaporated almost instantaneously in 1996. Most of the Gilad’s article consists of his speculations on why that happened. I agree with many of Gilad’s takes on this subject, but his involvement and perspective with Smalltalk started relatively late in the commercial Smalltalk lifecycle. I was there pretty much at the beginning so it seems appropriate to add some additional history and my own personal perspective. I’ll be directly responding to some of Gilad’s points, so you should probably read his post before continuing.
