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.

Reading CSV 180k records - Calculate something within 60 second time while grouping
A while back I needed to process CSV with millions of records in a timescale of seconds. Sylvan Data was the best fit in terms of speed and memory efficiency. It might help you. https://github.com/MarkPflug/Sylvan

CSV reader recommendations...
I maintain a couple libraries that aim to provide similar functionality to MTD: Sylvan.Data and Sylvan.Data.Csv.

Any tips on converting a XLSX file to HTML without using a licensed library?
Here is a simple, complete gist showing how to turn a DbDataReader into an HTML table. The WriteHtmlTable extension method can be used with any ADO.NET compatible driver, which the Sylvan.Data.Excel and Sylvan.Data.Csv libraries both support.

Need some help/direction reading CSV into MySQL without duplication
I maintain a couple libraries that can help with reading the data files: Sylvan.Data.Csv and Sylvan.Data.Excel. I see no reason to not allow users to provide whichever format is convenient for them.

How would I go about parsing a CSV like file that uses "SPACE" as delimiter and other quirks.
I maintain a CSV library, Sylvan.Data.Csv, that shouldn't have any issue parsing this. You'll need to explicitly specify that space (' ') is the delimiter.

Read uploaded excel file
Here is a some sample code of how to echo the contents of an Excel spreadsheet as CSV to the client browser using my libraries Sylvan.Data.Excel and Sylvan.Data.Csv:

Microsoft .net XLSX to CSV library?
I maintain a couple libraries that should make this quite easy: Sylvan.Data.Csv, and Sylvan.Data.Excel. They are both open-source and MIT licensed. They are also both fastest-in-class at their particular tast.

Using C# StreamReader in System.IO, I am able to read external .csv data and visualise the hell out of it in my C# app (CLUBASID).
Personally, I'd recommend Sylvan.Data.Csv, but being the author I'm probably a bit biased. Here is some CSV performance analysis that Joel Verhagen did for .NET libraries recently.

Faster MySQL with HTTP/3
MySqlConnector (the most popular .NET library for MySQL, and the one that I authored) has supported protocol compression for many years: https://github.com/mysql-net/MySqlConnector/issues/31.

Implementing the MySQL server protocol for fun and profit
> I kept technical notes about the protocol, to serve as a future reference for myself and for other developers.
As someone who's written a MySQL client (in C#: https://github.com/mysql-net/MySqlConnector), I'd be very interested to see your notes. Are they available anywhere, or were they the confidential IP of your client?
> Unsurprisingly, bugs were uncovered every time a new client was added.
I've faced the same thing, from a client perspective. Every time a new server is tested (MySQL, MariaDB, Amazon Aurora, Azure Database for MySQL, etc.), I find slightly different interpretations of the protocol and have to accommodate them.

Ask HN: Examples of Top C# Code?
I have had the pleasure of contributing to a couple different networked drivers with very talented maintainers that I like to use as references.
One supports a wide array of Framework versions and has both Sync and Async I/O, as it must to implement the ADO.NET database driver interfaces. Reading the internals really highlight the way that .NET has evolved over the years and what must be done in each target version to maximize performance:
https://github.com/mysql-net/MySqlConnector
The other supports .NET 6 only with Async I/O only. This support policy seems to be the way that "modern" .NET development is headed, as .NET 6 will be the floor for LTS .NET (formerly .NET Core) releases in a few months. Async APIs only greatly simplify development, and make it simpler to remain performant when targeting WASM.
https://github.com/Cysharp/AlterNats
As a library maintainer, one thing I often wonder about is how to indicate .NET version support. One option would be for the major version of the library to track the major version of .NET, so if I were to publish a new library today then start with .NET 6 support and start with version number 6.0.0 instead of 1.0.0. This would limit the library to only making breaking changes when the .NET version changes though.

Need some help/direction reading CSV into MySQL without duplication
Use the MySqlConnector to load the data into a temp table using the bulk copy API. Both of my libraries implement the IDataReader (DbDataReader) interface, so they can be directly used with the bulk copy APIs. Then insert into the final table from the temp table filtering out rows that are already in the final table.

Performance Improvements in .NET 6
I'm the author of what you might call the "new" MySQL ADO.NET library: https://github.com/mysql-net/MySqlConnector
I agree with your impression that developers of the other library don't seem to be "plugged in to" the .NET ecosystem. As an independent developer (not affiliated with Oracle or Microsoft), I've been able to influence GitHub PRs that shape the ADO.NET API for .NET 6.0, just by showing up and contributing; I haven't seen anyone from the Oracle MySQL team participating. Meanwhile, they violate basic principles of the .NET Framework Design Guidelines that have been around for over a decade (https://docs.microsoft.com/en-us/dotnet/standard/design-guid...), which makes their library feel alien to a .NET programmer (regardless of the quality issues it might have).
