  • Thinking Concurrently: How Modern Network Applications Handle Multiple Connections

    The idea behind a process is fairly simple. A running program consists of not only executing code, but also data and some context. Because the code, data and context all exist in memory, the operating system can switch from one process to another very quickly. This combination of code + data + context is known as a "process", and it's the basis for how Linux systems work.

    When you start your Linux box, it has a single process. That process then "forks" itself, such that two identical processes are running. The second ("child") process reads new code, data and context ("exec"), and thus starts running a new process. This continues throughout the time that a system is running. When you execute a new program on the command line with & at the end of the line, you're forking the shell process and then exec'ing your desired program in its place.

  • New Purist Services – Standard Web Services Done Ethically

    When you sign up for a communication service, you are typically volunteering to store your personal, unencrypted data on someone else’s remote server farm. You have no way of ensuring that your data is safe or how it is being used by the owner of the server. However, online services are incredibly convenient especially when you have multiple devices.

  • Automated compliance testing with InSpec

    Don't equate compliance through certification with security, because compliance and security are not the same. We look at automated compliance testing with InSpec for the secure operation of enterprise IT.

  • How the Kubernetes Certification Ensures Interoperability

    Dan Kohn, executive director of the Cloud Native Computing Foundation, has called the launch of the new Kubernetes service provider certification program the most significant announcement yet made by the Foundation around the open source container orchestration engine.

    On this new episode of The New Stack Makers from KubeCon + CloudNativeCon 2017, we’ll learn more from Kohn and William Denniss, a product manager at Google, about how the program can help ensure interoperability and why that’s so important.

  • Container Structure Tests: Unit Tests for Docker Images

    Usage of containers in software applications is on the rise, and with their increasing usage in production comes a need for robust testing and validation. Containers provide great testing environments, but actually validating the structure of the containers themselves can be tricky. The Docker toolchain provides us with easy ways to interact with the container images themselves, but no real way of verifying their contents. What if we want to ensure a set of commands runs successfully inside of our container, or check that certain files are in the correct place with the correct contents, before shipping?

  • Prometheus vs. Heapster vs. Kubernetes Metrics APIs

    In this blog post, I will try to explain the relation between Prometheus, Heapster, as well as the Kubernetes metrics APIs and conclude with the recommended way how to autoscale workloads on Kubernetes.

  • Google Introduces Open Source Framework For Testing Docker Images

    Google has announced a new framework designed to help developers conduct unit tests on Docker container images. 

    The Container Structure Test gives enterprises a way to verify the structure and contents of individual containers to ensure that everything is as it should be before shipping to production, the company said in the company’s Open Source blog Jan. 9. 

    Google has been using the framework to test containers internally for more than a year and has released it publicly because it offers an easier way to validate the structure of Docker containers than other approaches, the company said.

OSS Leftovers

  • Why no more new AND successful FOSS projects in the last ten years?
     

    If you ask me, the new, successful FOSS projects should be project that fix, replace, rewrite, whatever… the really unglamorous, low-level tools, libraries and so on that would make that happen. Yes, I know that this is really unlikely to happen under current business models and until IoT everywhere, new iPhones every year and the like are perceived as higher priorities, regardless of their environmental impacts and, very often, sheer lack of sense.

  • FOSS Backstage - CfP open
    It's almost ten years ago that I attended my first ApacheCon EU in Amsterdam. I wasn't entirely new to the topic of open source or free software. I attended several talks on Apache Lucene, Apache Solr, Hadoop, Tomcat, httpd (I still remember that the most impressive stories didn't necessarily come from the project members, but from downstream users. They were the ones authorized to talk publicly about what could be done with the project - and often became committers themselves down the road.
  • Liveblogging RIT’s FOSS projects class: initial questions for community spelunking
    Stephen Jacobs (SJ) and I are co-teaching “Project in FOSS Development” at RIT this semester, which basically means “hey students, want to get course credit for contributing to a FOSS project?” The class is centered around 5 project sprints of two weeks each. The first 3 weeks of class are preparing for the sprint periods; the week before spring break is a pause to reflect on how sprints are going. Otherwise, class efforts will be centered around executing project work… (aka “getting stuff done”).

  • Lawsuit accuses PACER of milking the public for cash in exchange for access
    The federally run online court document access system known as PACER now finds itself listed on a federal docket. Its overseer, the US government, is a defendant in a proposed class-action lawsuit accusing the service of overcharging the public. The suit, brought by three nonprofits on Thursday, claims millions of dollars generated from a recent 25-percent increase in page fees are being illegally spent by the Administrative Office of the Courts (AO). The cost for access is 10 cents per page and up to $3 a document. Judicial opinions are free. This isn't likely to break the bank for some, but to others it adds up and can preclude access to public records. The National Consumer Law Center, the Alliance for Justice, and the National Veterans Legal Services Program also claim in the lawsuit that these fees are illegal because the government is charging more than necessary to keep the PACER system afloat (as is required by Congress).
  • Is the Most Massive, Illegal Paywall in the World About to Come Down?
    A groundbreaking lawsuit is poised to decimate what is arguably the most unjust, destructive, and it now sounds like illegal paywall in the world, the Public Access to Court Electronic Records, PACER. PACER is the federal government court documents repository. Every federal court document, for every case, lives in PACER. It’s essentially a giant FTP document repository with a horrendous search system bolted on, not dissimilar to EDGAR. PACER was created in 1988 to enable access to court records electronically. Initially available only in courthouses the system was expanded to the web in 2001.

  • EE4J Code Begins the Journey to Open Source
    The EE4J project, which was created to manage the Eclipse Foundation’s stewardship of Java EE technologies following Oracle’s decision to open source them, is starting to gain traction. Soon after the project was created, EclipseLink and Yasson (the official reference implementation of Java JSON Binding, JSR-367) became the first two projects to be transferred under the EE4J umbrella. As reported in December, the announcement was made that seven more projects were being proposed.
