Programming: 'DevOps', Caddyfile, GCC 8.4 RC and Forth

A beginner's guide to everything DevOps
While there is no single definition, I consider DevOps to be a process framework that ensures collaboration between development and operations teams to deploy code to production environments faster in a repeatable and automated way. We will spend the rest of this article unpacking that statement.
The word "DevOps" is an amalgamation of the words "development" and "operations." DevOps helps increase the speed of delivering applications and services. It allows organizations to serve their customers efficiently and become more competitive in the market. In simple terms, DevOps is an alignment between development and IT operations with better communication and collaboration.
DevOps assumes a culture where collaboration among the development, operations, and business teams is considered a critical aspect of the journey. It's not solely about the tools, as DevOps in an organization creates continuous value for customers. Tools are one of its pillars, alongside people and processes. DevOps increases organizations' capability to deliver high-quality solutions at a swift pace. It automates all processes, from build to deployment, of an application or a product.

How to solve the DevOps vs. ITSM culture clash
Since its advent, DevOps has been pitted against IT service management (ITSM) and its ITIL framework. Some say "ITIL is under siege," some ask you to choose sides, while others frame them as complementary. What is true is that both DevOps and ITSM have fans and detractors, and each method can influence software delivery and overall corporate culture.

JFrog Launches JFrog Multi-Cloud Universal DevOps Platform
DevOps technology company JFrog has announced its new hybrid, multi-cloud, universal DevOps platform called the JFrog Platform that drives continuous software releases from any source to any destination. By delivering tools in an all-in-one solution, the JFrog Platform aims to empower organizations, developers and DevOps engineers to meet increased delivery requirements.
For the uninitiated, JFrog is the creator of Artifactory, the heart of the Universal DevOps platform for automating, managing, securing, distributing, and monitoring all types of technologies.

New Caddyfile and more
The new Caddyfile enables experimental HTTP3 support. Also I’ve added a few redirects to my new domain. All www prefix requests get redirected to their version without www prefix. My old domain nullday.de redirects now to my new domain shibumi.dev. Also I had to add connect-src 'self' to my CSP, because Google Lighthouse seems to have problems with defalt-src 'none'. If just default-src 'none' is being set, Google Lighthouse can’t access your robot.txt. This seems to be an issue in the Google Lighthouse implementation, the Google Search Bot is not affected.

Content Addressed Vocabulary
How can systems communicate and share meaning? Communication within systems is preceded by a form of meta-communication; we must have a sense that we mean the same things by the terms we use before we can even use them.
This is challenging enough for humans who must share meaning, but we can resolve ambiguities with context clues from a surrounding narrative. Machines, in general, need a context more explicitly laid out for them, with as little ambiguity as possible.
Standards authors of open-world systems have long struggled with such systems and have come up with some reasonable systems; unfortunately these also suffer from several pitfalls. With minimal (or sometimes none at all) adjustment to our tooling, I propose a change in how we manage ontologies.

GCC 8.4 Release Candidate available from gcc.gnu.org
The first release candidate for GCC 8.4 is available from https://gcc.gnu.org/pub/gcc/snapshots/8.4.0-RC-20200226/ ftp://gcc.gnu.org/pub/gcc/snapshots/8.4.0-RC-20200226/ and shortly its mirrors. It has been generated from git commit r8-10091-gf80c40f93f9e8781b14f1a8301467f117fd24051. I have so far bootstrapped and tested the release candidate on x86_64-linux and i686-linux. Please test it and report any issues to bugzilla. If all goes well, I'd like to release 8.4 on Wednesday, March 4th.

GCC 8.4 RC Compiler Released For Testing
GCC 8.4 will hopefully be released next week but for now a release candidate is available for testing the latest bug fixes in the mature GCC8 series.
GCC 8.4 is aiming for release next week as potentially the last of the GCC8 series while GCC 9.3 is also coming soon. GCC 8.4 represents all of the relevant bug fixes over the past year for back-porting to users still on GCC 8. GCC 10 (in the form of version GCC 10.1) meanwhile as the next feature release should be out in the next month or two.

Excellent Free Tutorials to Learn Forth
Forth is an imperative stack-based programming language, and a member of the class of extensible interactive languages. It was created by Charles Moore in 1970 to control telescopes in observatories using small computers. Because of its roots, Forth stresses efficiency, compactness, flexible and efficient hardware/software interaction.
Forth has a number of properties that contrast it from many other programming languages. In particular, Forth has no inherent keywords and is extensible. It is both a low level and high level language. It has the interesting property of being able to compile itself into a new compiler, debug itself and to experiment in real time as the system is built. Forth is an extremely flexible language, with high portability, compact source and object code, and a language that is easy to learn, program and debug. It has an incremental compiler, an interpreter and a very fast edit-compile-test cycle. Forth uses a stack to pass data between words, and it uses the raw memory for more permanent storage. It also lets coders write their own control structures.
Forth has often being deployed in embedded systems due to the compactness of object code. Forth is also used in boot loaders such as Open Firmware (developed by Sun Microsystems) as well as scientific fields such as astronomy, mathematics, oceanography and electrical engineering.

Samsung, Red Hat to Work on Linux Drivers for Future TechThe metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. |
