• GraalVM 22.2: Smaller JDK size, improved memory usage, better library support, and more!

  Today we’re releasing GraalVM 22.2! This release brings new features and lots of improvements to the developer experience — let’s go through the highlights!

  This release includes support for JDK 11 and JDK 17. As always, you can download GraalVM Community from GitHub, or get the GraalVM Enterprise builds from OTN. You can also install the latest version of GraalVM via the GraalVM Extension Pack for Java for VS Code or with Homebrew on macOS. Now, let’s take a look at what’s new in this release!

• Mirantis Acquires amazee.io to Bring NoOps to K8s - Container Journal

  Mirantis today announced it has acquired amazee.io to advance adoption of a “ZeroOps” approach to deploying applications in Kubernetes environments.

  Amazee.io’s open source Lagoon platform provides a layer of abstraction that analyzes how an application is constructed using containers on a local desktop or in a Git repository. Lagoon then automatically invokes the application programming interfaces (APIs) required to deploy that application on a Kubernetes cluster.

• Conciseness

  Conciseness is often considered a virtue among hackers and software engineers. FOSS maintainers in particular generally prefer to keep bug reports, questions on mailing lists, discussions in IRC channels, and so on, close to the point and with minimal faff. It’s not considered impolite to skip the formalities — quite the opposite. So: keep your faffery to a minimum. A quick “thanks!” at the end of a discussion will generally suffice. And, when someone is being direct with you, don’t interpret it as a slight: simply indulge in the blissful freedom of a discussion absent of faffery.

• ISTIO-SECURITY-2022-006

  Due to a process issue, CVE-2022-31045 was not included in our Istio 1.14.2 and Istio 1.13.6 builds.

  At this time we suggest you do not install 1.14.2 or 1.13.6 in a production environment. If you have, you may downgrade to Istio 1.14.1 or Istio 1.13.5. Istio 1.14.3 and Istio 1.13.7 are expected to be released later this week.

• XSAs released on 2022-07-26

  The Xen Project has released one or more Xen Security Advisories (XSAs). The security of Qubes OS is not affected. Therefore, no user action is required.

• A quick test of MongoDB 6.0 with syslog-ng - Blog - syslog-ng Community - syslog-ng Community

  Any time I see that one of the syslog-ng destinations has a major new version, I'm a bit scared, as it is not uncommon to introduce breaking changes with them. MongoDB 6.0, however, was a pleasant surprise. I gave it a quick try, and everything worked as expected. Along the way, I even learned about MongoDB Compass, an easy-to-use GUI for MongoDB databases.

  Note that I only did a quick test of MongoDB 6.0. I did not try the new 6.0 specific features. All I did was sending logs from syslog-ng to MongoDB and browsing the collected logs using MongoDB Compass.

• The Apache News Round-up: week ending 22 July 2022

  We’re wrapping up another great week with the following activities from the Apache community...

• Numeric Variable Names With Leading Zeroes | Tom Wyant [blogs.perl.org]

  Over on the p5p mailing list, a user raised the issue that use of variable $00 is an error starting with Perl 5.32, and asked that this "regression" be fixed.

  I have always understood that variables whose names begin with anything but an alphabetic or an underscore are reserved to Perl, and you mess with them at your peril. And this is the gist of the Porters' response to the post. Recent versions of perlvar say this explicitly, though earlier versions of that document restrict themselves to describing currently-implemented special variables.

• Uutils: Cross Platform Linux Core Utils In Rust!?! - Invidious

  The GNU core utils are fundamental to the Linux desktop but they're not the only option out there, one notable project is uutils which aims tocreate a set of cross platform core utils in rust

• Getting started with Django – A Simple CRUD application

  Django is a free and open-source, Python-based web framework that follows the model–template–views architectural pattern. Django advertises itself as “the web framework for perfectionists with deadlines” and “Django makes it easier to build better Web apps more quickly and with less code”. Django is known for the speed at which you can develop apps without compromising on robustness.

  When learning a new language or framework, a new way to go about it is to connect to the database and to architect a simple client to perform insert, read, update and delete records to it, i.e. CRUD.

• Jens Georg: dLeyna has moved

  The four previously separated repositories core, connector-dbus, renderer and server have been combined into this single repository. I was amongst those who promoted for the split, but since then the conditions have changed and it is far easier to maintain in an all-in-one repository now. Most files should have kept history.
