  • Why giving back is important to the DevOps culture

    In the DevOps CALMS model (which stands for Culture, Automation, Lean, Measurement, and Sharing), Sharing is often overlooked or misunderstood. While each element of CALMS is just as important as the others, sharing knowledge is something that we often neglect.

  • Convincing your manager that upstreaming is in their best interest

    In an ideal world, everyone would implicitly understand that it just makes good business sense to upstream some of the modifications made when creating your Linux powered devices. Unfortunately, this is a long way from being common knowledge, and many managers still need convincing that this is, in fact, in their best interests.

    Just so that we are clear, I'm not suggesting here that your next Linux powered device should be an entirely open design. We live in the real world and unless your explicit aim is to produce a completely open platform, doing so is unlikely to be good for your companies' profitabilty. What does make sense however is to protect the parts of your product that drive your value proposition, while looking for ways to reduce costs in places which don't drive the value add or unique selling point. This is where upstreaming and open source can offer you a massive advantage, if done right.

  • Paving new paths out of dead-end blog archive page navigation

    I’ve found some WordPress plugins and themes that have tried to do link up disparate archive pages by subtracting and adding one to the current month or year. This can lead to “navigational hazards” as they sometimes blindly link to months or years where there were no posts; creating 404 Not Founds and empty archive pages. It only takes a tiny extra effort to make sure that you only link to the next or previous page that actually have posts on them.

    You can apply similar solutions for other types of archive pages such as tag/topic and category archives. Try to provide good solutions for where a visitor may want to go next when they’ve reached the last page in a topic archive. You could suggest they go back to the front page or to a list of trending posts. Perhaps branch out to other related tags. There are many possible options here and the right choice will be up to how you’ve organized your website.

4 open source Markdown editors

Filed under
OSS

I do most of my writing in a text editor and format it with Markdown—articles, essays, blog posts, and much more. I'm not the only one, either. Not only do countless people write with Markdown, but there are also more than a few publishing tools built around it.

Who'd have thought that a simple way to format web documents created by John Gruber and the late Aaron Schwartz would become so popular?

While most of my writing takes place in a text editor, I can understand the appeal of a dedicated Markdown editor. You get quick access to formatting, you can easily convert your documents to other formats, and you can get an instant preview.

My open source journey: From Pong to microservices

Filed under
OSS

In 1990, I was a 9th grader living in Vietnam. I had never had access to a computer. One day my mother returned from a trip and gave me a book titled "How to program with Turbo Pascal." I was delighted—everything I read in that book made sense, and I started to write code on paper.

When the local university opened a computer lab that offered rentals, I spent all of my allowances for weeks, trying to write the classic Pong game in Pascal.

Soon after that, I moved to Austin, Texas, where I took computer programming courses in high school and community college. Since I needed a computer for school, I decided to build my own PC. A family friend who worked for IBM kindly offered to help install the operating system. My home-built PC seemed to give him a lot of trouble; it took nearly an entire evening to get everything working. To this day, I’m not sure why he decided to set up a dual-boot with Slackware Linux and IBM OS/2, but his decision had a positive impact on my path.

  • Anatomy of an OSS Institutional Visit

    I recently visited the UK Meteorology Office, a moderately large organization that serves the weather and climate forecasting needs of the UK (and several other nations). I was there with other open source colleagues including Joe Hamman and Ryan May from open source projects like Dask, Xarray, JupyterHub, MetPy, Cartopy, and the broader Pangeo community.

    This visit was like many other visits I’ve had over the years that are centered around showing open source tooling to large institutions, so I thought I’d write about it in hopes that it helps other people in this situation in the future.

  • The Future of Technological Advancement Is Open Source

    The influence of open source on the IT industry for the past few decades has been undeniable, and the scale and speed of the open source development have been remarkable. The primary reason behind this is, it is cost-effective and also provides an opportunity for faster and more reliable innovation which allows enterprises to scale their infrastructure. Many employers allow developers to work on projects within the given time frame. Removing internal restrictions about open source will encourage developers, rather than making them feel like they are violating IT policies.

    Employers are enabling developers to work in conjunction with the latest innovations and accelerate the way at which these technologies are being adopted. Open source is a crucial area one can encounter in the present and the future. It is quickly becoming a necessity for success as enterprises realize the benefits it can offer and also provides a cost-effective option as compared to proprietary alternatives.

  • Decisive leadership is needed even more acutely in the digital open source era

    I was speaking recently at a seminar in Switzerland about leadership in the age of digital disruption, and an interesting question came up. Someone asked me why I was propagating the need for strong, decisive leadership and at the same time talking about open source era. “Isn’t open source about getting results without a clear (singular) leadership?” he asked while citing examples of open source operating systems (OS) like Linux, social movements like the Arab Spring and the recent rise of cryptocurrencies.

    This gentleman went on to say he was really confused. “Not only does your claim about the need for strong leadership in the open source era go against the very essence of open source systems, you go to the extent of advocating autocratic leadership?”

  • Asynchronous vs Synchronous Python Performance Analysis

    This article is the second part of a series on using Python for developing asynchronous web applications. The first part provides a more in-depth coverage of concurrency in Python and asyncio, as well as aiohttp.

    If you'd like to read more about Asynchronous Python for Web Development, we've got it covered.

    Due to the non-blocking nature of asynchronous libraries like aiohttp we would hope to be able to make and handle more requests in a given amount of time compared to analogous synchronous code. This is due to the fact that asynchronous code can rapidly switch between contexts in order to minimize time spent waiting for I/O.

  • Preparing for 2019 Open Source Security Initiatives

    I read a very interesting article in the September-October 2018 issue of the Harvard Business Review entitled "Too Many Projects”, by Rose Hollister and Michael D. Watkins. The article, based on the author’s consulting work, detailed their observations around root causes of initiative overload, including impact blindness, multiplier effects, political logrolling, unfunded mandates, cost myopia and inertia. “Understanding those causes,” claim the authors "can help leaders diagnose the risks in their organizations and make smarter decisions about what to keep and what to kill.”

    On page 7 of the print edition (page 6 of the online edition), I noticed an interesting sidebar entitled “Questions to Ask Before You Launch an Initiative”. As I read through the sidebar I found my mind connecting the dots between these proposed project pre-launch questions and the selection of an open source security tool within an organization. All too often individuals suggest implementing an open source tool to address an organizational pain point because, at face value, open source tools have no upfront implementation cost. What happens, however, is that during the implementation the organization quickly realizes the unanticipated operational expenditures associated with their chosen tool.

  • Yubico Introduces Open Source YubiHSM SDK for Securing Infrastructures and Cryptographic Key Material

The YubiHSM 2 delivers the highest levels of security for cryptographic digital key generation, storage, and management, supporting an extensive range of enterprise environments and applications, in a cost effective and minimalistic form factor.

  • Drone.io gives open-source community free continuous integration service

    Continuous delivery platform provider Drone.io is giving back to the open-source community with the release of a continuous integration hosted service solution. Drone Cloud is being released to the open-source community for free with the help of bare metal cloud provider Packet.

    According to the company, the solution is being powered by infrastructure donated from Packet.

    “We were really excited about Brad’s (founder of Drone.io) reasons for rolling out Drone Cloud,” Jacob Smith, CMO of Packet, wrote in a blog post. “When he spoke about all of the Drone (and other) users who are building for an exploding set of architectures and operating systems. Pairing Intel, AMD, Arm and (hopefully soon) other bare metal systems with new features in Drone meant that our two small companies could make a real impact on a lot of projects.”

  • IVI Leads Progress in Value Assessment Through Open-Source Platform

    In recent weeks, CVS Caremark announced that it will be using ICER’s cost-effectiveness reports to determine coverage for drugs, using a specific cost per quality-adjusted life year (QALY) threshold for those determinations. This decision has led to vocal opposition and debate. Patient groups have spoken out strongly against the CVS approach, specifically objecting to the use of QALYs.

    Journal of Clinical Pathways spoke with Mark Linthicum, MPP, and Jennifer Bright, both with the Innovation and Value Initiative (IVI), regarding the need to find a rational middle ground and to work toward more tailored use of value information for decision-making.

    RISC OS is open sourced and available under the Apache 2.0 licence — it was one of the first operating systems to support the Raspberry Pi.

  • Web-Scale Companies Pioneer Open Line Systems, but Will Network Operators Follow?

    First, some background: An optical line system consists of optical amplifiers, multiplexers/demultiplexers and ROADMs. Historically, the line system has been tightly coupled with the terminal systems (i.e., transponders) with both line and terminal supplied by the same vendor. The end-to-end optical network has historically been a closed and proprietary system. Lately, though, some web-scale providers have concluded that this model stifles innovation and are bringing the concept of disaggregation to optical networking in the form of the open line system (OLS).

    An open line system decouples the optical line elements from the terminals to create several potential benefits for service providers, with rapid technology adoption being one of the biggest drivers. Coherent detection and photonic integration (including silicon photonics) have spurred rapid innovation in transponders, while line systems are evolving more slowly. Decoupling the line from the terminals allows service providers to advance through several generations of transponder technologies without having to change the line systems.

Researchers estimate that Python, Javascript, and R contribute billions to GDP

Filed under
Development
OSS

Gross domestic product, perhaps the most commonly used statistic in the world for evaluating economic progress, has some issues.

Increasingly, one of the biggest problems is that GDP generally underestimates the value of free goods and services—checking facts on Wikipedia or sharing photos on Instagram, for instance. GDP is best at measuring the impact of TV and car sales—not of things available for free or that require you to view ads, like broadcast TV or Facebook, explains the Financial Times’s Gillian Tett.

As a new research paper points out, this shortcoming also means GDP may be missing a lot of value created in the form of free programming languages (pdf). The most popular programming languages, like JavaScript and Python, are open source. This means that anyone can use them for free and modify them to develop new programs that they can then offer for free or for sale. JavaScript, for example, is used on about 95% of websites. Python, the most popular tool for data scientists, is used by companies like Google and Facebook to analyze data and develop new products.

Graphics: Android on DRM/KMS, NVIDIA's Proprietary Linux Driver

  • A dream come true: Android is finally using DRM/KMS
    In the beginning, Android did not really have a graphics stack. It was just pushing frames directly to framebuffers and hoping for the best, the approach worked for quite some time. However, over time, the usecases became more and more complex and a new graphics stack was necessary. About 6 years ago the Android team conducted a lot of research and quickly realized that the mainline kernel was far from being up to the job - it was lacking Atomic screen updates, explicit syncronization and support for low power hardware, among other things. Google was left with no other choice than to design their own graphic stack: Atomic Display Framework (ADF).

The NVIDIA 415.25 is out today in order to formally introduce support for the new TITAN RTX and Quadro RTX 8000 graphics cards, the newest Turing-based products. The TITAN RTX is available beginning today from the NVIDIA store at $2499 USD meanwhile the flagship RTX 8000 card will retail for about $10k USD.
  • NVIDIA's Proprietary Linux Driver Might Soon Work On Fedora Silverblue
    Fedora's Silverblue initiative formerly known as Fedora Atomic Workstation currently doesn't work with the NVIDIA binary driver, but that soon could change. For Fedora Silverblue to ultimately move forward and gain adoption, it will need to work with NVIDIA hardware and that means supporting their proprietary driver. It's simply a fact with the open-source Nouveau driver not being good enough for the vast majority of NVIDIA GPU owners and these green graphics processors being found in many Fedora Linux boxes. Due to how Fedora Silverblue is currently composed, the NVIDIA proprietary driver doesn't currently work but there are changes being worked on in order to support the binary blob's workflow.

It’s used as a giveaway at conferences and other events. The original handbook was written in Czech in 2015 and the English version released last year introduced only cosmetic changes, so even though the handbook has pretty generic info and is not specific to any Fedora release there were quite a lot of changes needed.

KDE Applications 18.12 were released last thursday. Those are in ports, but haven’t made it around to the official packages yet. So here are some notes on almost-current KDE on almost-current FreeBSD: Installing modern KDE: from a freshly installed 12-R system, getting to a KDE Plasma desktop is a matter of installing two metapackages: pkg install xorg kde5 . That will leave you in a state where you need to link .xinitrc to startkde .. rather old-school. For purposes of having a pleasant setup, pkg install falkon quassel sddm as well.

    Metrics and telemetry are fundamental in any engineering activity to evaluate, learn and improve.

Open Source projects has been traditionally reluctant to promote telemetry, based on privacy concerns. Some factor that comes to my mind are helping to change this perception...
