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.

Reverse engineering the plotting process
No need to reverse engineer anything. It's explained in all the detail you need in the Chia Proof of Space Construction document. It's implemented in chiapos though I find madmax's implementation of the plotter to be easier to read: https://github.com/madMAx43v3r/chia-plotter/tree/master/include/chia

Revolutionary New Pool & Plotting Mechanism?
If true, my assumption is they are implementing a Hellman attack on Table 1. Chia already describes the process here: https://github.com/Chia-Network/proofofspace/blob/master/proof_of_space.md#Hellman-Attacks and gives example code here: https://github.com/Chia-Network/chiapos/tree/main/hellman_example

Changing chia plot file keys (memo)
I'm trying to farm plots created with different keys on a different machine. I know that I could add the plotter machine's keys to the farming machine and there is no official way to edit plots and change keys, but I'm interested in hacking things and looking at plotter_disk.hpp of chiapos, this is how the header (first few bytes) of a plot file looks like:

hpool says plots bad, Chia GUI farms them
git clone https://github.com/Chia-Network/chiapos.git cd chiapos && mkdir build && cd build && cmake .. && make -j8 ./ProofOfSpace check -f plot-k32-???.plot \[num\_iterations\]

Has someone compiled the 20% improvement "combined" chiapos for windows?
Is this the branch https://github.com/Chia-Network/chiapos/commit/369c9e773d9d43b00696771aad46cc5b4c54e785 ?

Plotting destination file system
on my list above is just hard to do perfectly unless you specifically engineer the system that way. Thsi project probably manages to hit erasure blocks just right by virtue of the fact that it uses fairly large files, but it could probably be tuned to work better. You could maybe get partway there by changing the internal buffer size of the buffered disk in the plotter and recompiling/pip install-ing the plotter. In that case the buffer size would need to be the same size as the erasure block size of the SSD (or a multiple of it), but that is generally ~64-128MB these days. This approach would also cause somewhat higher memory consumption because the internal buffer size is for each bucket in each sort manager that is being actively written to, so more buckets with a larger buffer -> more RAM use (this is outside the memory limit you set on the command line).
-
Plotting with temp in RAM slower that expected.
By the time you get to NVME you are definitely CPU starved; give it more buckets and leave RAM at 3390. I dont think you can go past 512 without applying https://github.com/Chia-Network/chiapos/pull/202

Simple way to SAFELY update to the multithreaded chiapos library on Linux / MacOS
The changes from https://github.com/Chia-Network/chiapos/commits/main commit cleanly into combined with the exception of the std::cout << "Using optimized chiapos"; bits which can be manually fixed, just FYI.

Has someone compiled the 20% improvement "combined" chiapos for windows ;
combined: https://github.com/pechy/chiapos/tree/combined edit: after the fantastic help of this community I managed to compile it myself. Here are ⠀two plot logs for comparison. Default chiapos vs "combined": https://www.chiaplotsimulator.com/?data=y53ab38k

I rebased the performance improvements for the default plotter to the newest version
The best version that I know of was by github user pechy (https://github.com/pechy/chiapos/) and the results ( around 12% improvement overall ) were shown here https://www.reddit.com/r/chia/comments/nk92th/plotting_speed_improvements/
