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.

What hash function you use for hash maps / hash tables?
I recently switched to wyhash as it seems to have a good combination of speed and stability.

Are there any weaker hashes than MD5, but still randomly distributed?
wyhash is a decent option for if you don't need a cryptographical quality hash

New Bare Hash Map: 2X-3X Speedup over SOTA
I feel like you’d want something a bit safer than “we don’t store the keys and just rely on the hash to be really good” [1], putting “please do not use this for serious tasks” in a comment embedded in the header file isn’t a clear enough warning.
It’s not clear to me that that probability of collision assumptions hold. It’s basically assuming that the hashing is perfect and distributes any inputs to the full 64-bit space with uniform probability. That’s the usual hash map / randomized algorithm hope, but does BigCrush or similar avalanche testing really prove that? (Presumably not, otherwise there wouldn’t be image attacks for things like md5).

- wyhash and wyrand are a non-cryptographic 64-bit hash function and PRNG respectively

Can dwmblocks be used with other window managers aside from dwm?
I see. Thanks for suggesting lemonbar. lemonblocks and lemonaid also use signals like dwmblocks, so those can be my alternatives.
- Lemonaid - A block manager for lemonbar (Lemonbar)
- Update Certain "Blocks" in Lemonbar
What are some alternatives?
smhasher - Hash function quality and speed tests
succade - Run, feed and style your Lemonbar with ease
aHash - aHash is a non-cryptographic hashing algorithm that uses the AES hardware instruction
