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.

Redict is an independent, copyleft fork of Redis
https://github.com/dragonflydb/dragonfly is another option. Not a fork but API-compatible reimplementation.

Redis License Changed
Check out DragonflyDB (BSL): https://www.dragonflydb.io/
BSL is not OSI-approved, but it’s a much more reasonable AWS-resistant license. It’s the same license CockroachDB uses, for example.
KeyDB (BSL, acquired by Snapchat) is also an option: https://keydb.dev/
BSL is a much better license, but it’s a gamble on how long KeyDB will be supported. I don’t want to mess around with such a core part of my architecture.

Dragonfly Cache Design
If you have not heard about Dragonfly - please check it out. It uses - what I hope - novel and interesting ideas backed up by the research from recent years [1] and [2]. It's meant to fix many problems that exist with Redis today. I have been working on Dragonfly for the last 7 months and it has been one of the more interesting and challenging projects I've ever done!

Generating Income from Open Source
I recently ran across the the license for Dragonfly [1] which has some restrictions (rights reserved), but 5 years after the license date the license switches to Apache 2.0. Basically a timed-limited rights reservation. I don't hate it. I might even contribute to such a project for free.
I would consider something like this: When I release code, it's rights reserved for 5 years, then open-source (and this baked into an irrevocable license). Anyone may use the software for non-commercial purposes. Anyone may contribute, those who contribute will be granted permission for commercial use if I deem their contributions significant enough. Anyone may distribute the software under these terms.
If such a model became popular, I have a hard time imagining it could make things any worse. It might even accelerate open-source development. You might say, "but it's not open-source", fair enough, but we can view it as open-source contribution with a delay. For example, if this model became wildely popular this year, and we saw great progress with this model, then come 2028 we would be flooded with new open-source software and ultimately might be better off than it would have been without this model.
(And this whole thing makes me rethink copyright and patents and how much they really contribute to society. Perhaps they should be shortened?)

Dragonfly – The most performant in-memory data store on Earth
2. You are right, I need to shut the fuck up and let self-righteous hn crowd with torches do what they do best - find a weakness, and push it until they get bored and switch to beat another builder. You asked me about my perspectives and priorities? These are my priorities: https://github.com/dragonflydb/dragonfly/graphs/contributors
> Developers do not want to manage a cluster of single cpu processes. Not on their laptops and not in the production. And it's not just about management complexity. See this https://github.com/dragonflydb/dragonfly/issues/1229 and it's just one example. Single cpu - is just not enough for today use-cases.
That may all very well be the case – let us assume it is for the sake of the argument although I have some comments about that as well – but that still means the argument is "Redis is too complex to run on multiple CPUs" and/or "Redis is poor for these workloads" (I didn't investigate that issue in-depth), and not "Redis is unable to do much work with this very powerful AWS instance". There two are very different things. There is no nuance anywhere in the benchmark. A reader might very well believe that this is all the performance they're going to get out of Redis on that machine, which that's clearly not the case.

Nokia was designed as strongest and most affordable phone, yet you use Iphone that costs 1000$. it's not about how it was designed but whether it addresses your current needs.

The first version of Redis, written in Tcl
I think this is relevant... These are 3 OSS databases that can be an alternative to Redis:
- KeyDB: https://github.com/snapchat/keydb
- Dragonfly: https://github.com/dragonflydb/dragonfly
- Skytable: https://github.com/skytable/skytable
I have used keyDB before. The raft consensus makes building an HA Redis easy.

Test Data Libraries for Elixir
The factory library ExMachina created by Thoughbot uses function names and generates an atom used to call factories. For example:

Please critique my rather simple portfolio website
Take a look at https://thoughtbot.com/ for a dark themed site. The site has both a light and dark theme which is triggered by your system setting (on macos: System Preferences > General > Appearance)

Ask HN: Who wants to be hired? (November 2021)
Location: Charleston, SC
Remote: Yes
Willing to relocate: Probably not
Technologies: Rust, Elixir, Ruby, Blockchain, Solidity
Résumé/CV: https://docs.google.com/document/d/1RK7hqiLKhMhXcopzG8oKDGhC...
Email: [email protected]
Hello,
After working at [thoughtbot](https://thoughtbot.com/) for five years I just finished building my own blockchain. Moonshine Exchange has realtime transaction settlement and pulled in >$100K in liquidity organically without any outside funding. I'm looking for my next gig, not necessarily in the blockchain space. Rust and Elixir preferred but open to any technology!
