​​Beartype is an open-source pure #python PEP-compliant O(1) constant-time runtime type checker emphasizing efficiency, portability, and thrilling puns.

Beartype brings Rust inspired zero-cost abstractions into the lawless world of dynamically-typed pure Python.

Beartype is portably implemented in Python 3, continuously stress-tested via GitHub Actions + tox + pytest, and permissively distributed under the MIT license. Beartype has no runtime dependencies, only one test-time dependency, and supports all Python 3.x releases still in active development.

​​REST API for any Postgres database.

Using PostgREST is an alternative to manual CRUD programming. Custom API servers suffer problems. Writing business logic often duplicates, ignores or hobbles database structure. Object-relational mapping is a leaky abstraction leading to slow imperative code. The PostgREST philosophy establishes a single declarative source of truth: the data itself.

Declarative Programming: It’s easier to ask PostgreSQL to join data for you and let its query planner figure out the details than to loop through rows yourself. It’s easier to assign permissions to db objects than to add guards in controllers. (This is especially true for cascading permissions in data dependencies.) It’s easier to set constraints than to litter code with sanity checks.

Leak-proof Abstraction: There is no ORM involved. Creating new views happens in SQL with known performance implications. A database administrator can now create an API from scratch with no custom programming.

​​Clearly is a real time monitor for your celery tasks and workers. Clearly see and debug your celery cluster in real time!

> While I do like flower, to me it's not been totally up to the task (pun intended :).
Why is that? flower needs page refreshes, filters only one task type at a time, displays results as plain strings without any formatting or syntax highlighting, and on top of that also truncates them!

> And clearly is actually real time, has multiple simultaneous filters, a beautiful syntax highlighting system, an advanced formating system that shows parameters, results and tracebacks just as an ipython would, has complete un-truncated results and is very easy to use! Also you can install it very easily with a docker image!

> It's great to actually see in a totally real time way what's going on in your celery workers! So it's very nice for inspecting, debugging, and even demonstrating your company async-superpowers (put clearly on a big screen TV showing all tasks of your production environment)!

> Clearly is composed of a server, which collects real time events from the celery cluster, generates missing states, and streams filtered data to connected clients; and a client, which you use to send filter commands and display both real time and stored data. They communicate with each other via gRPC and ProtocolBuffers.

​​Free/Libre Open Source Software Binaries of VSCode

Microsoft’s vscode source code is open source (MIT-licensed), but the product available for download (Visual Studio Code) is licensed under this not-FLOSS license and contains telemetry/tracking. According to this comment from a Visual Studio Code maintainer:

> When we Microsoft build Visual Studio Code, we do exactly this. We clone the vscode repository, we lay down a customized product.json that has Microsoft specific functionality (telemetry, gallery, logo, etc.), and then produce a build that we release under our license.

> When you clone and build from the vscode repo, none of these endpoints are configured in the default product.json. Therefore, you generate a “clean” build, without the Microsoft customizations, which is by default licensed under the MIT license

The VSCodium project exists so that you don’t have to download+build from source. This project includes special build scripts that clone Microsoft’s vscode repo, run the build commands, and upload the resulting binaries for you to GitHub releases. These binaries are licensed under the MIT license. Telemetry is disabled.

The Open Architecture Playbook. Use it to create better and faster (IT)Architectures. OSS Tools, templates and more for solving IT problems using real open architecture tools that work!

Smart people have been thinking on how to create IT architectures as long as there has been computers. Ideas come and go, however creating a good architectures can still be complex and time consuming. Especially when you try to invent the wheel for yourself. With this interactive playbook you can create your IT architecture better and faster. The focus of this architecture playbook is in on:

1. Knowledge reuse. Why reinvent the wheel again? It is far and more fun to create a better wheel for your organisation or IT project instead! Focus on the hard complex context specific issues. Use good open tools and knowledge for the easy 80%!
2. Easier creation of architecture documents and deliverables. This playbook has an extensive list of all open tools available for creating your IT architecture or design. Using these open tools will speed up the process of creating your architecture deliverables and reduce your risks.
3. Quality improvement. By making use of content parts provided for various architecture deliverables you will lower your business risks. Complex business IT projects will fail. Now and in future. But if you make use of proven methods and tools developed from decades of IT architecture scientific research you will lower the risk for your project. Architecture will help to make your projects more successful in terms of costs, speed and profitability.
