Servers: "Docker Not Doomed?" and Some IBM/Red Hat Leftovers

Filed under

  • Docker Not Doomed?

    Modern application development essentially consists of composing an application from a variety of services. These services aren't just infrastructure components that live on a server any more. They're delivered via an API and could be almost anything underneath as the abstractions start to pile up.

    COBOL code at the other end of a message bus with a lambda-function frontend? Okay. Ephemeral container running a Spring Boot service that connects to an RDBMS on a physical Unix server on the other side of the country? Sure, why not? Modern applications don't really care, because it's all about getting the job done. The name of the game is loosely-coupled modular components.

    This is why Docker has joined forces with Microsoft, Bitnami, HashiCorp, and a few others to create the Cloud Native Application Bundle (CNAB) specification. Docker uses this spec as part of its Docker App tool, which behaves a lot like docker-compose to collect a variety of services together into a single application bundle that can be shared around. It's a lot like a container collection, and brings the same easy portability of containers to composed applications.

    "[Docker App] allows you to describe not just containers, but other services around which the app is dependent," says Johnston. "And it allows you to do things that enterprises care about, such as signing the bundle, verifying that signature, and automatically promoting it based on that signature and things like that."

  • Red Hat OpenShift Service Mesh is now available: What you should know

    As Kubernetes and Linux-based infrastructure take hold in digitally transforming organizations, modern applications frequently run in a microservices architecture and therefore can have complex route requests from one service to another. With Red Hat OpenShift Service Mesh, we’ve gone beyond routing the requests between services and included tracing and visualization components that make deploying a service mesh more robust. The service mesh layer helps us simplify the connection, observability and ongoing management of every application deployed on Red Hat OpenShift, the industry’s most comprehensive enterprise Kubernetes platform.

    Red Hat OpenShift Service Mesh is available through the OpenShift Service Mesh Operator, and we encourage teams to try this out on Red Hat OpenShift 4 here.

  • Submit a KSyntaxHighlighting Color Theme

    The KSyntaxHighlighting framework provides support for color themes. These color themes specify all colors (text/background/selection/…) and font style roles (italic/bold/…) that are used for the highlighting. The definition happens in some easy to understand JSON file format. Starting with the upcoming KDE Frameworks 5.75 release, all KTextEditor framework based application will support these color themes for their embedded editors. This includes Kate & KWrite, but naturally a lot more, like for example KDevelop, Kile and RKWard. [...] With the recent additions we already cover some more well known text editor color themes. But if you just search a bit around the internet or look what other text editors ship per default, we still lack a lot of well known ones. For example even our GitLab instance provides the Monokai theme in the configuration for its web highlighting that we still lack. Therefore, we are eager to get submissions for more MIT licensed color themes we can bundle with KSyntaxHighlighting. All users of applications using this framework will enjoy to be able to choose between more themes with ease if you help us! Therefore, take the chance and help us out, provide some more themes as merge request. License must be MIT, this seems to be no problem for most themes out there, at least it seems most of the ones I stumbled over are MIT licensed.

  • FreeBSD Instant-workstation 2020

    A little over a year ago I published an instant-workstation script for FreeBSD. The idea is to have an installed FreeBSD system, then run a shell script that uses only base-system utilities and installs and configures a workstation setup for you. [...] The script is updated intermittently when new PRs come in, or when I have to reinstall a machine and things do not behave the way I think they should. If you want a quick live KDE Plasma experience with FreeBSD, head on over to FuryBSD which does live ISO images with a variety of environments.

  • Three tips to implement Kubernetes with open standards

    The technologies chosen by enterprise IT departments today will have a long-term impact on their performance, operations and overall strategy. Sometimes it can take well over a decade to realize the full implications of a technology solution. This can put a great deal of weight on the shoulders of IT management, especially when it comes to emergent technologies whose utility, importance and trajectory may not yet be fully known. Placing a bad bet on new software can lead to difficult integrations and disruptions across an organisation’s entire tech stack, which in the long-term can lead to lost productivity, wasted budgets, and the likelihood of losing ground to competitors. Kubernetes, the open source container orchestration platform, was until recently regarded in the same way, with IT departments struggling to fully appraise its long-term value. However, with Kubernetes now running 86 per cent of container clusters, it has emerged as the de facto standard for cloud-native infrastructure. This means that the main concern for IT departments is not whether Kubernetes has a future, but how to ensure that their implementation of Kubernetes has a future which doesn't present a bottleneck to integrations, industry practices and use cases.

  • The Expandables – snapcraft extensions and the secret code

    If you’re a snap developer, you know that snap development is terribly easy. Or rather complex and difficult. Depending on your application code and requirements, it can take a lot of effort putting together the snapcraft.yaml file from which you will build your snap. One of our goals is to make snap development practically easier and more predictable for everyone. To that end, we created a framework of snap extensions, designed to make the snap journey simpler and more fun. In a nutshell, extensions abstract away a range of common code declarations you would normally put in your snapcraft.yaml file. They help developers avoid repetitive tasks, reduce the knowledge barrier needed to successfully build snaps, offer a common template for application builds, and most importantly, save time and effort. But what if you want – or need – to know what is behind the abstraction?

  • Researchers were able to figure out which American phone numbers use Signal
           
             

    Privacy flaws in contact discovery have led to a research team being able to enumerate all American Signal users. Enumeration means that using the contact discovery built into the Signal app, researchers were able to perform a large-scale crawling attack and figure out which American phone numbers were attached to a Signal account. The new research paper was released by Christoph Hagen, Christian Weinert, Christoph Sendner, Alexandra Dmitrienko, and Thomas Schneider. It is titled: “All the Numbers are US: Large-scale Abuse of Contact Discovery in Mobile Messengers.”

  • The ’90s are back: Gateway laptops have been resurrected as Walmart exclusives

    Remember Gateway laptops? If you grew up in the ’90s, they were probably the brand of your first laptop. Like a revival of your favorite childhood television show, the Gateway brand has been raised from the dead — cow imagery and all. The brand, which is owned by computer maker Acer, is making its own comeback with a line of new laptops, tablets, and convertibles that will be exclusive to Walmart.

    So, what’s forcing these cows out of hibernation? For Gateway parent Acer, its about new silicon from Intel and AMD, including the successsul new mobile Ryzen 4000 processors.

The Top 50 Programming Languages to Learn Coding

  • Benefits Of Using Odoo For Small Businesses

    In this tutorial, we will be showing you how using Odoo can benefit a small or medium-sized business. As times have progressed, businesses big and small have become more complex in their operations. With several departments having to function and share information to one another, the need for an integrated system has grown by leaps and bounds. More and more small business are implementing ERP systems. In fact, once an ERP system is implemented, it often becomes the backbone of many corporate-scale businesses. Such systems can seamlessly integrate business lifecycles, such as production, inventory management, order processes, and more. An example of this system would be Odoo, one of the most popular ERP systems currently available.

  • Best WordPress Backup Plugins 2020

    It is at most important to keep multiple backups of your WordPress site. In case the website is compromised or any plugin update breaks your site, WordPress backups can help you restore it quickly. Mainly, a WordPress site consists of three important parts, the database, user-created files such as plugins, themes, and uploaded files, and finally the WordPress core files. If anyone of these three parts is missing or corrupted, the website will not function properly or will not function at all. When we create a backup, we create a backup of the site database and the user-created files. WordPress core files can be downloaded and installed separately.

  • Parsing PAN-OS logs using syslog-ng

    Version 3.29 of syslog-ng was released recently including a user-contributed feature: the panos-parser(). It is parsing log messages from PAN-OS (Palo Alto Networks Operating System). Unlike some other networking devices, the message headers of PAN-OS syslog messages are standards-compliant. However, if you want to act on your messages (filtering, alerting), you still need to parse the message part. The panos-parser() helps you create name-value pairs from the message part of the logs. From this blog you can learn why it is useful to parse PAN-OS log messages and how to use the panos-parser().
