Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Calculating extrusion for custom-generated G-code?
Here (at the bottom of the page) you can find an overview of the calculation and the git repository also holds the entire source code of the Cura Engine (which is the part of Cura that actually does the slicing and G-code creation) where the calculations happen. The repository is in C++, but the calculations are actually universal.

✨Cura 5.3.0-beta.1 ✨ ~ 75+ new 3D Printers available + Updated Recommended Menu + Interlocking Structures 🐊
There have been some improvements but I would not say it's fixed yet. 😕 It is my favorite 5.x seam for sure! You can read about the work done here: https://github.com/Ultimaker/CuraEngine/pull/1762

New Cura feature! Maximum volumetric flow rate setting!
If you can figure git and out how to compile Cura and CuraEngine from source, you can test it by using the "vms" branch on both my CuraEngine and Cura github forks.

If you want to contribute by testing it you can find the necessary commits for Cura here and here for CuraEngine.

Pipeline to automate the process from creating 3d objects to start a print job
I am currently developing a pipeline for creating STL files, slice them and create a print job based on it. My setup at the moment is an Ultimaker S5, which offers a simple REST-API, for example starting a job with a G-Code or UFP file. I am using the cadQuery library for creating parametrized 3d shapes and export them as a STL file. I want to use the CuraEngine CLI interface (Backend for Cura) for slicing or their library libArcus (python bindings) but there is literally no documentation or any kind of examples, except the source code. There is also the prucaSlicer, which also offers a CLI interface for creating G-Code, but no support for the Ultimaker S5.

Ultimatemaker Cura 5.0.0 (Problem) Vs. Creality Slicer 4.8.2. As you can see in the video Cura should have done the bridging longwise left to right rather than shortwise. What setting in Ultimatemaker Cura 5.0.0 do I have to change to fix this?
Bridges are hard to detect because of the workflow of the slicing engine. To put it simply: a bridge cannot be detected until the perimeter is layed down. But since both in the Cura Engine (which btw is now also at the core of the perimeters in PS) and in the Slic3r the Area generator operates simultaneously on periters and skin, it's impossible to inject in the pipeline and change the skin orientation. For two reasons: -First, they cannot detect a bridge because the start and end point are arbitrary and not static. It does make sense for us, but not for the algorithm. -Second, they cannot define an orientation. It cannot see that is a rectangle, and that therefore it should be best to lay the skin following a path parallel to the longest side.

Hitting every branch on the way down
It's because they changed the versioning format: https://github.com/protocolbuffers/protobuf/releases?page=5
But I suppose old version still receive bugfixes.

Reverse Engineering Protobuf Definitions from Compiled Binaries
For at least 4 years protobuf has had decent support for self-describing messages (very similar to avro) as well as reflection
https://github.com/protocolbuffers/protobuf/blob/main/src/go...
Xgooglers trying to make do on the cheap will just create a Union of all their messages and include the message def in a self-describing message pattern. Super-sensitive network I/O can elide the message def (empty buffer) and any for RecordIO clone well file compression takes care of the definition.
Definitely useful to be able to dig out old defs but protobuf maintainers have surprisingly added useful features so you don’t have to.
Bonus points tho for extracting the protobuf defs that e.g. Apple bakes into their binaries.

Add extra stuff to a “standard” encoding? Sure, why not
> didn’t find any standard for separating protobuf messages
The fact that protobufs are not self-delimiting is an endless source of frustration, but I know of 2 standards:
- SerializeDelimited* is part of the protobuf library: https://github.com/protocolbuffers/protobuf/blob/main/src/go...
- Riegeli is "a file format for storing a sequence of string records, typically serialized protocol buffers. It supports dense compression, fast decoding, seeking, detection and optional skipping of data corruption, filtering of proto message fields for even faster decoding, and parallel encoding": https://github.com/google/riegeli

Block YouTube Ads on AppleTV by Decrypting and Stripping Ads from Profobuf
It looks like it is in fact universal. Just glancing at the code here, it looks like the tool searches any arbitrary file for bytes that look like encoded protobuf descriptors, specifically looking for bytes that are plausibly the beginning of a FileDescriptorProto message defined here:
https://github.com/protocolbuffers/protobuf/blob/main/src/go...
This takes advantage of the fact that such descriptors are commonly compiled into programs that use protobuf. The descriptors are usually embedded as constant byte arrays. That said, not all protobuf implementations embed the descriptors and those that do often have an option to inhibit such embedding (at the expense of losing some dynamic introspection features).

What's involved in protobuf encoding?
Not much. You can check the source code in https://github.com/protocolbuffers/protobuf. For example, for serializing a boolean in C#: https://github.com/protocolbuffers/protobuf/blob/main/csharp/src/Google.Protobuf/WritingPrimitives.cs#L165. Strings and objects are a bit more complicated, but it is all about turning the data into its byte representation.
