Velero gives you tools to back up and restore your Kubernetes cluster resources and persistent volumes. You can run Velero with a public cloud platform or on-premises.

Velero lets you:

• Take backups of your cluster and restore in case of loss.
• Migrate cluster resources to other clusters.
• Replicate your production cluster to development and testing clusters.

Velero consists of:

• A server that runs on your cluster
• A command-line client that runs locally

• Supports WireGuard for all of the above, in addition to Android and Windows 10
• Generates .conf files and QR codes for iOS, macOS, Android, and Windows WireGuard clients
• Generates Apple profiles to auto-configure iOS and macOS devices for IPsec - no client software required
• Includes a helper script to add and remove users
•Blocks ads with a local DNS resolver (optional)
• Sets up limited SSH users for tunneling traffic (optional)
• Based on current versions of Ubuntu and strongSwan
• Installs to DigitalOcean, Amazon Lightsail, Amazon EC2, Vultr, Microsoft Azure, Google Compute Engine, Scaleway, OpenStack, CloudStack, Hetzner Cloud, Linode, or your own Ubuntu server

CIDER is the Clojure(Script) Interactive Development Environment that Rocks!

CIDER extends Emacs with support for interactive programming in Clojure. The features are centered around cider-mode, an Emacs minor-mode that complements clojure-mode. While clojure-mode supports editing Clojure source files, cider-mode adds support for interacting with a running Clojure process for compilation, debugging, definition and documentation lookup, running tests and so on.

Norfair is a customizable lightweight Python library for real-time 2D object tracking.

The features are:

• Any detector expressing its detections as a series of (x, y) coordinates can be used with Norfair. This includes detectors performing object detection, pose estimation, and instance segmentation.

• The function used to calculate the distance between tracked objects and detections is defined by the user, making the tracker extremely customizable. This function can make use of any extra information, such as appearance embeddings, which can heavily improve tracking performance.

• Modular. It can easily be inserted into complex video processing pipelines to add tracking to existing projects. At the same time it is possible to build a video inference loop from scratch using just Norfair and a detector.

• Fast. The only thing bounding inference speed will be the detection network feeding detections to Norfair.

Faust is a stream processing library, porting the ideas from Kafka Streams to Python.

It is used at Robinhood to build high performance distributed systems and real-time data pipelines that process billions of events every day.

Faust provides both stream processing and event processing, sharing similarity with tools such as Kafka Streams, Apache Spark/Storm/Samza/Flink.

Ash is a resource based framework for building Elixir applications.

Traditional MVC Frameworks (Rails, Phoenix, etc) leave it up to the user to build the glue between requests for data (HTTP requests in various forms as well as server-side domain logic) and their respective ORMs. In that space, there is an incredible amount of boilerplate code that must get written from scratch for each application (authentication, authorization, sorting, filtering, sideloading relationships, serialization, etc).

Ash is an opinionated yet configurable framework designed to reduce boilerplate in an Elixir application. Ash does this by providing a layer of abstraction over your system's data layer(s) with Resources. It is designed to be used in conjunction with a phoenix application, or on its own.

Python's map(): Processing Iterables Without a Loop

Python’s map() is a built-in function that allows you to process and transform all the items in an iterable without using an explicit for loop, a technique commonly known as mapping. map() is useful when you need to apply a transformation function to each item in an iterable and transform them into a new iterable. map() is one of the tools that support a functional programming style in Python.

In this tutorial, you’ll learn:

- How Python’s map() works
- How to transform different types of Python iterables using map()
- How to combine map() with other functional tools to perform more complex transformations
- What tools you can use to replace map() and make your code more Pythonic

SWR is a React Hooks library for remote data fetching.

The name “SWR” is derived from stale-while-revalidate, a HTTP cache invalidation strategy popularized by HTTP RFC 5861. SWR is a strategy to first return the data from cache (stale), then send the fetch request (revalidate), and finally come with the up-to-date data.

Magisk is a suite of open source tools for customizing Android, supporting devices higher than Android 4.2. It covers fundamental parts of Android customization: root, boot scripts, SELinux patches, AVB2.0 / dm-verity / forceencrypt removals etc.

Here are some feature highlights:

- MagiskSU: Provide root access to your device
- Magisk Modules: Modify read-only partitions by installing modules
- MagiskHide: Hide Magisk from root detections / system integrity checks
