The intent of this specification and related tools is to expand the reach of development containers, allow the usage of containers by themselves or different orchestration technologies, and allow any tool to manage and create them.

A development container allows you to use a container as a full-featured development environment. It can be used to run an application, to separate tools, libraries, or runtimes needed for working with a codebase, and to aid in continuous integration and testing.

A GitHub Action and an Azure DevOps Task are available for running a repository's dev container in continuous integration (CI) builds. This allows you to reuse the same setup that you are using for local development to also build and test your code in CI.

Our development container teams across Microsoft and GitHub continue active development on the new Dev Container Specification, and this iteration had several exciting highlights.

But more so, external style cannot be applied to a subsection of a web page unless they force it into an iframe, which has all sorts of issues of it's own which is why external CSS is usually ignored. Inline CSS is often stripped by the tag strippers who don't want you turning things on or off... and media queries shouldn't even play into it since the layout should be controlled by the page it's being shown inside (for webmail) or the client itself, NOT your mail.

Or you can use Maybe container! It consists of Some and Nothing types, representing existing state and empty (instead of None) state respectively.

Snaps each pick a ‘base’, for example, Ubuntu18 (corresponding to the set of minimal debs in Ubuntu 18.04 LTS). Nevertheless, the choice of base does not impact on your ability to use a snap on any of the supported Linux distributions or versions — it’s a choice of the publisher and should be invisible to you as a user or developer.

Determining this exact byte position within one massive mdat in each respective file is not trivial.

The Moov atom can only exist after recording is complete when the relevant metadata can now be created for the stored data.

MP4 containers are structured in such a way that the a/v data is stored without frame headers and the Moov atom is a table, listing the byte positions and byte lengths for each a/v frame. The Moov atom can only exist after recording is complete when the relevant metadata can now be created for the stored data.

Docker images

container images

Image consumers can enable DCT to ensure that images they use were signed. If a consumer enables DCT, they can only pull, run, or build with trusted images. Enabling DCT is a bit like applying a “filter” to your registry. Consumers “see” only signed image tags and the less desirable, unsigned image tags are “invisible” to them.

In the examples below, we are using Docker images tags to specify a specific version, such as docker:19.03.8. If tags like docker:stable are used, you have no control over what version is going to be used and this can lead to unpredictable behavior, especially when new versions are released.

It is a multi-stage image which reproduces the following operations:Construction of the artefacts in a build imageAvailability of the compilation process in a minimal image

Bottlerocket OS Welcome to Bottlerocket! Bottlerocket is a free and open-source Linux-based operating system meant for hosting containers. Bottlerocket is currently in a developer preview phase and we’re looking for your feedback. If you’re ready to jump right in, read our QUICKSTART to try Bottlerocket in an Amazon EKS cluster. Bottlerocket focuses on security and maintainability, providing a reliable, consistent, and safe platform for container-based workloads. This is a reflection of what we've learned building operating systems and services at Amazon. You can read more about what drives us in our charter. The base operating system has just what you need to run containers reliably, and is built with standard open-source components. Bottlerocket-specific additions focus on reliable updates and on the API. Instead of making configuration changes manually, you can change settings with an API call, and these changes are automatically migrated through updates. Some notable features include: API access for configuring your system, with secure out-of-band access methods when you need them. Updates based on partition flips, for fast and reliable system updates. Modeled configuration that's automatically migrated through updates. Security as a top priority.

Instead of allowing any and all components to fetch and manipulate data, which can make debugging pretty much suck, we want to implement a pattern that's in line with the Single Responsibility Principle, and that keeps our code DRY.
