​​Introducing: storybook-addon-performance

An experimental storybookjs addon to help better understand and debug performance for #react components.

Features:
- Zero config (except for interactions): Generate performance information relating to server-side rendering and client-side mounting without any configuration
- Pin results: You can run some tasks, pin the result, make some changes, rerun the tasks and see what changed
- Interactions: Add your own custom user interactions to run as a parameter to your story. This lets you time how long interactions take. The API for this is super flexible and powerful!
- Control: Run all tasks for an overview, or run individual tasks to drill down on specific problems
- Marked: All tasks are marked with the User Timing API to allow for easy debugging of individual tasks in your browser's performance profiler

​​Terminal multiplexer inspired by i3 and tmux.

3mux is a terminal multiplexer with out-of-the-box support for search, mouse-controlled scrollback, and i3-like keybindings. Imagine tmux with a smaller learning curve and more sane defaults.

​​In a chord diagram (or radial network), entities are arranged radially as segments with their relationships visualised by arcs that connect them. The size of the segments illustrates the numerical proportions, whilst the size of the arc illustrates the significance of the relationships1.

Chord diagrams are useful when trying to convey relationships between different entities, and they can be beautiful and eye-catching.

​​Compile #nim Extensions for #python On Import!

Pros:
- Performance: Nim compiles to C
- Reduce cloud computing costs without writing C
- Leverage both language's ecosystems: Python for breadth, Nim for performance.
- Seamless integration with existing Nim code by using the Nimpy library.
- Very low effort to create high-performance Python extensions using Nim.
- 100% transparent to end users (doesn't require Nim compiler).

​​Contextualise is a simple and flexible tool particularly suited for organising information-heavy projects and activities consisting of unstructured and widely diverse data and information resources -- think of investigative journalism, personal and professional research projects, world building (for books, movies or computer games) and many kinds of hobbies.

> On a side note, an alpha version of Contextualise is already available at https://contextualise.dev. It is not advised, at this stage, to use Contextualise for anything other than testing purposes. Data could be irrevocably lost!

​​View and control remote terminals from your browser with end-to-end encryption.

TermPair lets developers securely share and control terminals in real time. Before termpair sends terminal output to the server, it encrypts it using a secret key so the server cannot read it. The server forwards that data to connected browsers. When the browsers receive the data, they use the secret key to decrypt and display the terminal output.

Likewise, when a browser sends input to the terminal, it is encrypted in the browser, forwarded from the server to the terminal, then decrypted in the terminal by termpair and written to the terminal's input. The secret key is generated by termpair and embedded in a part of the url that is not sent to the server.

Functional Abstraction Layer for C++

Cefal is a C++20 header-only library with abstractions over basic functional programming concepts (and using C++20 concepts). It is more a research pet project than a production-ready library (especially keeping in mind it compiles only on GCC/master for now).

​​Deal - #python library for design by contract (DbC) programming.

That's nice assert statements in decorators style to validate function input, output, available operations and object state. Goal is make testing much easier and detect errors in your code that occasionally was missed in tests.

Features:
- Automatic property-based tests.
- Static analysis.
- Generators and async coroutines support.
- External validators support.
- Type-annotated and mypy-friendly.
- Specify allowed exceptions for function.
- Invariant for all actions with class instances.
- Decorators to control available resources: forbid output, network operations, raising exceptions.
- You can disable contracts on production.
