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.
trie
- Filtering an object by comparing a list of strings the object has with another blacklisted list of strings, taking into account wildcards?
-
Finding distinct values in an big list, fast
A quick google found me this package. Can be installed via NuGet under the name ktrie. Just ran a few little tests in a test project and the StringTrieSet seems like the best fit for what you are trying to do.
- Memory efficient way to store strings in runtime.

Ask HN: How many of you are self employed?
Started 10 years ago as an open-source project, building an algorithm for audio fingerprinting. Added a commercial offering, selling storage built specifically for audio fingerprints, targeting enterprise customers. Since the offering was too technical (it's hard to sell solutions to problems that are too narrow and domain-specific), pivoted to more "business-oriented problems". This last year's pivot is a chance to finally grow. Running a business in single-player mode is, at times, too stressful. Aside from the technical part, which I very much enjoy, I need to wear marketing, sales, and customer support hats.

Ask HN: What apps have you created for your own use?
The OP said elsewhere they are using this[1] library, which allows you to specify minimum seconds to match, so you'd presumably set it to match 20 seconds or whatever minimum length podcast commercials usually are.
Most other audio fingerprinting libraries I've seen allow you to specify min/max time, as well.
HTH.

- [P] Is it feasible to find a mapping between two non-synthesized audio signals of the same audio sequence?

HN: == Happy New Year HN == (What is your “plans” for the new year?)
My goal for the next year is just to work fewer hours. Covid pushed my work habit to the extreme, and I need to rebalance.
1. Read more books, less social media/news.
2. Spend more time with my friends. I haven't seen some of them IRL for more than a year.
3. Exercise more, play tennis with my daughter, spend quality time with my kids.
4. Spend more time with my parents. They've become visibly older in the last years, an observation that scares me.
5. Focus more on marketing for the businesses that I've bootstrapped. All the shiny new features that are developed are not as important as getting more people to use your product.
6. Promote open-source project to 1k GitHub stars[1]. I know it isn't very meaningful, but it's just nice to receive a bit of recognition from the community.
7. Enjoy life, don't stress about all the little things that happen along the way.
Happy new year!
