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.

OOP in C
I’ve built it for now in a separate branch called “self”:
git clone -b self https://github.com/Sentido-Labs/cedro.git

What do you think about a C transpiler?
Currently, it does not make any difference whether this is one token or more because it is sent to the compiler exactly the same as it came in, but you could write a macro/plugin (src/macros/] that recognized this pattern and inserted a space right before the minus “-” sign.

Show HN: Loop macros, label break, slices in C with the Cedro preprocessor
Hi, when I presented the first release here 8 months ago (https://news.ycombinator.com/item?id=28166125) it got interesting comments and today I’ve made a new release with additional features:
- Break out of nested loops: break label; (https://sentido-labs.com/en/library/cedro/202106171400/#labe...)
- Notation for array slices: array[start..end] (https://sentido-labs.com/en/library/cedro/202106171400/#slic...)
- Loop macros: #foreach { ... #foreach } (https://sentido-labs.com/en/library/cedro/202106171400/#loop...)
The possibility of loop macros was discussed in this thread: https://news.ycombinator.com/item?id=28166698
At the time I hadn’t figured out how to make it useful without type information, but now it works. The same for the array slice notation: it took me a while to figure out how to make it do something useful without reflection, with a purely syntantical transformation.
Loop macros are useful for the kind of things for which you would use x-macros (https://en.wikipedia.org/wiki/X_Macro), with the advantage that it does not pollute the global namespace with macro names and the body of the macro stays more similar to the final result, which makes big macros easier to read.
Since it runs before the standard C preprocessor it can do things like building up `_Generic` macros as shown in the loop macro vec example: https://sentido-labs.com/en/library/cedro/202106171400/#loop...

is there a c function exit hook?
If pre-processing your code is an acceptable compromise, my Cedro pre-processor has that feature: passing a file through it produces standard C code for your compiler, and it includes a wrapper cedrocc that can be used in Unix/POSIX-style systems like Linux as a drop-in replacement for GCC: https://github.com/Sentido-Labs/cedro/

Keeping POWER relevant in the open source world
What I’d like to do is a quick proof-of-concept to see whether whatever instructions are available in my CPU can be leveraged for UTF-8 en-/decoding.
For instance, does it work any better than my C implementation? https://github.com/Sentido-Labs/cedro/blob/master/src/cedro....
Maybe the compiler already compiles that to an optimal SIMD version, I don’t know.

coloring point cloud
My elegant, state of the art solution, is a modification of the code found here https://github.com/IntelRealSense/librealsense/blob/development/wrappers/python/examples/opencv_pointcloud_viewer.py Some time before line 295 I use open cv to open the video device and poll the frames, then on line 296 I swap color_image with my new frame.... It kindof works, now I need to align the image and depth
- What’s the most comparable device to the iPhones TrueDepth camera?

Help a newbie out
Not sure if you have sorted it now but did a quick search up on the internet. Their github page has some installation instructions and as others have said you forgot to add the public server key. (source: https://github.com/IntelRealSense/librealsense/blob/master/doc/distribution_linux.md)

Green Chili and how to find them?
ok folks, I got an answer from the guy from intel and he pointed to me a github discussion. That post mostly answer my question. D435 was able to pick up small thin object in 3d point cloud so i am going for D435 for my chili.
