  • 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.

    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.

    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.

Why Windows Power Users Break Linux

As more people come to Linux, those of us who help the Windows refugees make the switch will need to be very patient with them. The more someone knows about Windows, the more likely it is that they will break Linux. Handing them a Linux laptop and saying, “Here ya go…” is not enough if they are going to succeed. You’re going to have to hold their hand for a while and telling them to “RTFM” will just drive them back to Windows. Understanding why they struggle as much as they do will help you to help them avoid some of the common pitfalls. I specialize in helping people get started with Linux. I’ve helped hundreds of people over the last few years and I can pretty much spot the ones who are going to do well and those who are going to be frustrated. If a client approaches me and they start the conversation with “I’ve been using Windows for 20 years…” I know it’s going to be a bumpy ride. The pattern is always the same: I walk them through an install and all is well for about two weeks and then I get a frustrated message from them about how Linux is stupid and doesn’t work. I know without asking that they’ve broken something major or borked up the whole system. I usually can fix the problem and make a good lesson out of it for them. I have gone so far as to walk them through a second installation from scratch. If the system is totally hosed, that’s the best way to go. Give them a clean slate to work with and hope they learned something. On the other hand, if a client tells me that they know nothing about computers but they need one to get things done like writing documents, spreadsheets, web surfing and email then they usually have zero issues. I get them setup and I don’t hear from them again. I usually contact then after a month or two and they invariably tell me everything is working perfectly. I got a call from a gentleman I hadn’t heard from in a year and a half recently. He said everything was working nicely but he wanted some advice about upgrading his Linux Mint from 17.3 to 18.1 and could I help him get it right. No problem. Wonderful to hear that all is well!

IBM/Red Hat/Fedora Leftovers

  • Making compliance scalable in a container world

    Software is increasingly being distributed as container images. Container images include the many software components needed to support the featured software in the container. Thus, distribution of a container image involves distribution of many software components, which typically include GPL-licensed components. We can't expect every company that distributes container images to become an open source compliance expert, so we need to build compliance into container technology. [...] Package maintainers and package management tools have played an underappreciated role in source availability for over two decades. The focused nature of a package, the role of a package maintainer, and the tooling that has been built to support package management systems results in the expectation that someone (the package maintainer) will take responsibility for seeing that the sources are available. Tools that build binaries also collect the corresponding sources into an archive that can be delivered alongside the binaries. The result is that most people don't need to think about source code availability. The sources are available in the same unit as the delivery of the executable software and via the same distribution mechanism; for software delivered as an RPM, the corresponding source is available in a source RPM. In contrast, there is no convention for providing the source code that corresponds to a container image. The many software components in a container image often include GPL-licensed software. Companies that may not have much experience with distribution of FOSS software may begin distributing GPL-licensed software when they start offering their software in the form of container images. Let's make it straightforward for everyone, including companies who may be new to FOSS, to provide source code in a consistent way.

  • The (non-)return of the Python print statement

    In what may have seemed like an April Fool's Day joke to some, Python creator Guido van Rossum recently floated the idea of bringing back the print statement—several months after Python 2, which had such a statement, reached its end of life. In fact, Van Rossum acknowledged that readers of his message to the python-ideas mailing list might be checking the date: "No, it's not April 1st." He was serious about the idea—at least if others were interested in having the feature—but he withdrew it fairly quickly when it became clear that there were few takers. The main reason he brought it up is interesting, though: the new parser for CPython makes it easy to bring back print from Python 2 (and before).

    In this episode, we worked on a view to enroll students into a grade level for the school year. I added all the context data and used Tailwind to design the form layout to pick from a list of available grade levels. We added a variety of unit tests to prove the correctness. The enrollment page needed three pieces of data in the context to complete the form. We added the student, school_year, and grade_levels data to the context and wrote tests to show the data in there. We also protected that data from any erroneous access by another user. When the data was set, we worked on the template for the form. I set the header to make the enrollment action clear and created the radio input selectors to show the different grade level options. We cleaned up the design and user experience by including some Tailwind CSS classes which made the radio inputs much easier to select. At the end of the stream, we wrote the happy path test for the POST request to prove that the enrollment record exists after submission.

Managing tasks with todo.txt and Taskwarrior

One quote from Douglas Adams has always stayed with me: "I love deadlines. I like the whooshing sound they make as they fly by". We all lead busy lives and few ever see the bottom of our long to-do lists. One of the oldest items on my list, ironically, is to find a better system to manage all my tasks. Can task-management systems make us more productive while, at the same time, reducing the stress caused by the sheer number of outstanding tasks? This article looks at todo.txt and Taskwarrior. The management of tasks is rather personal and people have completely different approaches and philosophies. This is, of course, reflected in the requirements for, and expectations from, a task manager. Requirements can also change as our interaction with computers changes. For example, while I put a lot of emphasis on managing tasks via the command line in the past, these days I'm more interested in a good mobile app (to add tasks on the go and to receive reminders) and web support (to get an overview of all tasks). A good way to filter tasks is also essential for me. One of the reasons for using task-management software is so you can stop worrying about tasks until they become relevant. This requires a way to find relevant tasks when needed, such as when the due date is coming up soon or because you're in a relevant setting or place (often called a "context" in task-management systems). Going to the supermarket would be a good time to bring up a shopping list, for example. Task-management systems offer a number of ways to organize information that can be used in filters, such as tags, contexts (often stored as tags in the form of @tag, such as @home), and lists. In a series of two articles, we'll review four systems for managing tasks and to-do items around which open-source ecosystems have formed. Read more
