Debian Developers' Blogs on Technical Work

  • Markus Koschany: My Free Software Activities in June 2020

    Welcome to gambaru.de. Here is my monthly report (+ the first week in July) that covers what I have been doing for Debian. If you’re interested in Java, Games and LTS topics, this might be interesting for you.

  • MessagePack vs CBOR (RFC7049)

    I recently wanted to choose a binary encoding. This was for a project using Rust serde, so I looked at the list of formats there. I ended up reading about CBOR and MessagePack. Both of these are binary formats for a JSON-like data model. Both of them are "schemaless", meaning you can decode them without knowing the structure. (This also provides some forwards compatibility.) They are, in fact, quite similar (although they are totally incompatible). This is no accident: CBOR is, effectively, a fork of MessagePack. Both formats continue to exist and both are being used in new programs. I needed to make a choice but lacked enough information. I thought I would try to examine the reasons and nature of the split, and to make some kind of judgement about the situation. So I did a lot of reading [11]. Here are my conclusions.

  • Debian PPC64EL Emulation

    In my post on Debian S390X Emulation [1] I mentioned having problems booting a Debian PPC64EL kernel under QEMU. Giovanni commented that they had PPC64EL working and gave a link to their site with Debian QEMU images for various architectures [2]. I tried their image which worked then tried mine again which also worked – it seemed that a recent update in Debian/Unstable fixed the bug that made QEMU not work with the PPC64EL kernel. Here are the instructions on how to do it.

Hardware: Wainlux, RasPi, Arduino

  • Wainlux K6 & Alfawise C50 Mini Laser Engravers Offered for $130 and Up

    A few days ago I saw Wainlux K6 “most compact, powerful and simple-to-use” laser engraver on Kickstarter for about $159. I did not think too much of it at the time, but this morning I thought it already showed up for pre-order on GearBest for $129.99 as Alfawise C50. But I was mistaken, as both products are different, albeit sharing some of the same attributes. Nevertheless, this brought back my curiosity about these types of devices, especially with Wainlux K6 having already managed to raise over $200,000 from close to 1,400 backers so far. So let’s look at both.

  • Travel the world with a retro musical phone
  • Deck out your ride with an Arduino-controlled spoiler

    Car spoilers can provide downforce for better performance, or simply give the appearance of speed. To take things to another level, Michael Rechtin designed his own custom wing that doesn’t just sit there, but pitches up and down via a pair of servos. The system utilizes an Arduino Nano along with an MPU-6050 for control, adjusting itself based on his Mazda’s movement, and powered is supplied by a LiPo battery. Suction cups are used to attach the spoiler, so installation appears to require no actual modification of the car whatsoever.

Programming: XML, Perl and Rust

  • 10 Excellent Free Books to Learn XML

    XML is a set of rules for defining semantic tags that describe the structure and meaning of a document. The user of XML chooses the names and placement of the tags to convey the nature of the data stored in a document. XML can be used to markup any data file to make it easier to understand and process. In addition, it has been applied to many special domains of data: mathematics, music, vector graphics, the spoken word, financial data, chemical symbols, and web pages among others. Here’s our recommended free books to master XML.

  • 2020.28 Bridges 7

    Arne Sommer, inspired by a solution of a previous Weekly Challenge, wrote a small series of blog posts about the seven bridges of Königsberg:

  • A tour with Net::FTP

    When we want to have a way to exchange files between machines, we often think about rsync, scp, git or even something slow and complex (looking at you Artifactory and S3), but the answer is often right in front of your eyes: FTP! The “File Transfer Protocol” provides a very simple and convenient way to share files. It’s battle-tested, requires almost no maintenance, and has a simple anonymous access mechanism. It can be integrated with several standard auth methods and even some virtual ones, none of which I show here. [...] I got the idea to backup and centralize automatically the configuration file during the creation of the build pipeline workspace. It was intended to help both developers (configuration “samples”) and support team (see history, versioned then we can check diffs, file to replay). The constraints were to be able to exchange file from various places with variable users. The FTP protocol is a perfect fit for that. I added also a cronjob to autocommit and push to a git repository and we had magically a website listing versioned configurations files. In addition, FTP proved later to also require zero support. I mean really zero maintenance!

  • Perl Mongers, Unite!

    pm.org is great for resources, but there's no obvious way to promote your meeting. Not that there needed to be when the meetings were local events, but now, thanks to Covid-19, these meetings are taking place virtually. Why limit yourself to your local members? I am convinced that there are plenty of pockets of mongers that, if united and connected, would make the world realize that Perl Is Not Dead.

  • Programming languages: Now Rust project looks for a way into the Linux kernel

    The makers of systems programming language Rust are looking at how to adapt the language for use in the Linux kernel. Josh Triplett, an Intel engineer and lead of the Rust language project, says he'd "love to see a path to incorporating Rust into the kernel", as long as it's done cautiously and doesn't upset Linux kernel creator Linus Torvalds.

IBM/Red Hat Leftovers

  • Command Line Heroes: Becoming a Coder
  • Bank of America, Google, and Red Hat Executives Join OASIS Board of Directors

    OASIS, the international standards and open source consortium, today announced that three new members were elected to its Board of Directors: Jeremy Allison of Google, Rich Bowen of Red Hat, and Wende Peters of Bank of America. Their depth of experience in the open source and open standards communities bolsters the Board’s reach and establishes OASIS as the home for worldwide standards in cybersecurity, blockchain, privacy, cryptography, cloud computing, IoT, urban mobility, emergency management, and other content technologies. These three new members join the continuing members of the Board: Martin Chapman of Oracle, Bruce Rich of Cryptsoft, Jason Keirstead of IBM, Beth Pumo of Kaiser Permanente, and Daniel Reidel of New Context. Reelected Board members Frederick Hirsch, Individual member; Gershon Janssen, Individual member; and Richard Struse of Mitre will each serve a two-year term starting in July 2020.

  • OpenStack @ 10: Red Hat’s take on a decade of customer defined clouds and an update on Red Hat OpenStack Platform

    From the early days, Red Hat has supported the OpenStack project and we’ve built a platform of our own with Red Hat OpenStack Platform. This month, we look back at how far OpenStack has come in the last 10 years, how Red Hat has contributed and lastly, we celebrate the general availability of our next version with Red Hat OpenStack Platform 16.1, available later this month. [...] By 2014, Red Hat was already a major contributor to the project. This not only brought enterprise support from a heavily-invested contributor, but also helped drive community input from customers who may not otherwise have participated. The increasing diversity and chorus of voices within the community helped bring forth new projects and features to solve problems. In addition, the introduction of Red Hat OpenStack Certification widened industry support, launching with more than 100 tech industry leaders as members. The Icehouse (I) and Juno (J) releases coincided with Red Hat OpenStack Platform’s three-year support life cycle, launched with Red Hat OpenStack Platform 5. This meant that enterprises could choose a platform and standardize on it for an extended period, providing stability for the workloads that need it. Red Hat OpenStack Platform 6 kept the ball rolling with more than 700 enhancements, updates and changes to the platform as it continued to grow and mature.

  • How Automation can help banks improve security, compliance, and productivity

    FSIs spend a lot of time responding to auditors. Compliance with regulatory mandates often dictates processes. However, variance in processes can increase tension between developers working to improve the organization’s agility; teams responsible for maintaining operations; and security and compliance teams. Without a clear joint process, each of the teams may develop their own. Inconsistent IT configurations, patching and testing can make management and reporting difficult. A lack of shared processes can also allow technical debt to build, which inhibits change and introduces risk. In addition to managing digital transformation, IT systems are upgraded regularly, entailing an intense period where the IT team focuses on configuration and testing every piece of technology. While this work is critically important, and because the risk exposure is significant if each component is not updated and tested, it is also stressful and can be tedious. The challenge is further increased because many financial organizations are operating across a range of different environments, like Windows, Linux, public and private clouds, virtualized and container environments, increasing the complexity of their IT footprint.

  • My Outreachy Internship: The journey so far…

    I’ve gotten stuck with many issues over the coding period, some more facepalm than others. For example, I wasted almost a week trying to get my setup running on docker-compose only to realize that the problem was just mislabelled services. In another one, while writing a script to initialize a MySQL db I put a space after the ‘-p’ so my builds kept failing. Of course, these issues shouldn’t have taken more than a couple of hours to figure out but more often than not it took days. All this reminds me of the struggle I had when I started learning JavaScript. Trusting the environment/ecosystem did not come easy. It was normal for me to think that the bugs that I was getting were because of a bigger force that I did not understand yet. This would force me to blindly go on an expedition to really understand what’s going on.. only to realize that the issue was right in front of me and I never needed to read anything beyond the files that I wrote. However, even after the time I had lost the net result was always positive. The more ‘blind expeditions’ I went on the more knowledge I accumulated and the more confidence I gained to commit. A bigger hurdle for me has been adjusting to the work-from-home lifestyle. Especially with the pandemic my entire routine has been disrupted and finding a balance has been a challenge.

  • Introduction to Red Hat Insights

    Red Hat Insights is a SaaS application that is available free of charge to everyone with a valid Red Hat Enterprise Linux (RHEL) subscription. This article provides a brief introduction to Red Hat Insights, shows how RHEL systems are integrated into the cloud service, and lists key documents and resources related to the service. Author's note: I'm testing the service as part of my job at the Bielefeld IT Service Center (BITS) at Bielefeld University. This article reflects my personal view of Red Hat Insights. Furthermore, I would like to clarify that I am a member of the Red Hat Accelerators community.

  • Developing and testing on production with Kubernetes and Istio Workspace

    Due to container-orchestration platforms like Kubernetes and Red Hat OpenShift, developers have become very efficient about deploying and managing distributed and containerized applications. But can we say the same about application development and testing? In this article, I briefly discuss how cloud-native development is transforming the traditional development cycle of coding, building, and testing. I then introduce the idea of testing on production, not as a meme but as a necessity. Finally, I introduce Istio Workspace, a tool for developers working with distributed systems running on Kubernetes or OpenShift. [...] Testing new functionality before it reaches production has always been hard, but the shift from monoliths to microservices has brought scale, which has increased the challenge of testing locally. We see developers trying to use tools like Red Hat CodeReady Containers or Minikube to spin up whole applications composed of multiple services. While this approach works well when projects are relatively small, it’s not so easy when you introduce more fine-grained services, and the graph starts to grow. It is not feasible to spin up even a medium-sized distributed system on your own machine. Using replicated environments such as staging or quality engineering (QE) gives some confidence, but it’s expensive in terms of both cost and maintenance. Despite the effort of defining infrastructure as code, there are still potential differences in the target machines’ configuration; they just show up on the operating system and hardware level. It is also frequently impossible to get the same load and volume of data on the test system that is in the actual system. Therefore, testing on production is no longer a meme: It’s a reality and a necessity. What’s needed is a way to use your favorite tools to develop, build, and debug your code locally, but have your application behave as if it were running in the production cluster.
