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.

Qt does drag & drop for development, Can it do that for the end UI too?
I've used this in a few projects as have my students. https://github.com/paceholder/nodeeditor Seems to work well.

I think I've managed to port my 2D/3D Engine to Linux [free download link in description]
Then a follow-up: is that a hand-rolled node system or nodeeditor?

mCaptcha: Open-source proof-of-work captcha for websites
Asymmetric PoW algorithms, such as Cuckoo Cycle [1] or the poorly named Equihash [2] (which is not a hash function) do not lend themselves to password hashing, since a given instance can have 0 or 1 or many solutions.

Crypto: My Part in Its Downfall
The full technical report describing the LOCKSS forerunner to bitcoin may be downloaded at [1]. Interestingly, LOCKSS used a memory bound Proof-of-Work, where both prover and verifier perform a random walk in a 1GB table. But the prover had to do this many times, to obtain some final hash with many leading zeroes. This was before the invention of asymmetric PoW systems like Cuckoo Cycle [2] where the PoW can be verified with no memory use.

Is it possible a PoW that runs arbitrary algorithms?
A non-hashcash-style PoW scheme is Cuck(at)ooCycle.

POW Captcha: a lightweight, self-hosted proof-of-work captcha
The use of scrypt as underlying hash function is a rather poor choice though, as scrypt's memory hardness makes PoW verification unnecessarily expensive.
It's perfectly possible to make a memory hard PoW that's instantly verifiable, by using something other than hashcash. Examples include Cuckoo Cycle [1], and Equihash [2].

Memory-bound trapdoor proof of work
Non-Solution #8: Cuckoo Cycle https://github.com/tromp/cuckoo Why: At least a few people have looked at it, and any attacker is far more likely to directly attack the blockchain itself, than my server (which doesn't get involved with the blockchain) Why not: The "mathematical specification" https://github.com/tromp/cuckoo/blob/master/doc/mathspec is woefully inadequate, their "C spec" focuses more on ASCII art than actual readability https://github.com/tromp/cuckoo/blob/master/doc/spec and as https://handshake.org/files/handshake.txt points out, cannot be easily adjusted in difficulty. Also, I would need to implement it from scratch, but I guess I'll have to do that anyway.

Ask HN: What Kind of Threat Does Quantum Computing Pose to Bitcoin?
The hashcash proof-of-work scheme that bitcoin uses is vulnerable to Grover's quantum search algorithm, that can find a solution in the 2^76 search space for the current target difficulty in roughly sqrt(2^76) = 2^38 quantum hashing steps, for a 2^38 factor speedup.
Other proof-of-work schemes (e.g. finding cycles in graphs [1]) are not vulnerable to quantum speedup.

Theoretically, how much hashing power could a 'quantum computer' generate? And is any superpower close to having one yet, that we know of?
