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).

Tools besides Go for a newbie
IDE: use whatever make you productive. I personally use vscode. VCS: git, as golang communities use github heavily as base for many libraries. AFAIK Linter: use staticcheck for linting as it looks like mostly used linting tool in go, supported by many also. In Vscode it will be recommended once you install go plugin. Libraries/Framework: actually the standard libraries already included many things you need, decent enough for your day-to-day development cycles(e.g. `net/http`). But here are things for extra: - Struct fields validator: validator - Http server lib: chi router , httprouter , fasthttp (for non standard http implementations, but fast) - Web Framework: echo , gin , fiber , beego , etc - Http client lib: most already covered by stdlib(net/http), so you rarely need extra lib for this, but if you really need some are: resty - CLI: cobra - Config: godotenv , viper - DB Drivers: sqlx , postgre , sqlite , mysql - nosql: redis , mongodb , elasticsearch - ORM: gorm , entgo , sqlc(codegen) - JS Transpiler: gopherjs - GUI: fyne - grpc: grpc - logging: zerolog - test: testify , gomock , dockertest - and many others you can find here

Questions regarding prepared statements in database/sql
I understand that database/db is an abstraction. As to the driver, sorry, it completely went out of my head. The guide primarily focuses on https://github.com/go-sql-driver/mysql, which is also what I’m interested in.

Make Deno MySQL driver works better
Authentication method mismatch is not allowed to occur more than once. It is not a part of MySQL protocol. go-sql-driver also has the same rule.

Question about inserting date into MySQL?
If you are using https://github.com/go-sql-driver/mysql you need to add parseTime=true to the DSN to be able to use time.Time.

> mysql_real_escape_string is still vulnerable when being used with some exotic character sets
Indeed -- mysql_real_escape_string "mostly" fixes this problem by requiring a connection as one of its args, and since it's usually aware of the connection state, it can check that to see if one of those exotic charsets is in-use. But the problem is that there are multiple ways to change the connection charset, some of which the driver is aware of (e.g. in PHP mysqli set_charset) but some it is not (running textual statements like SET NAMES or SET CHARACTER SET).
But generally an attacker won't ever have the ability to set an arbitrary exotic character set for the connection, unless they already have some other sql injection mechanism, in which case it's a moot point :)
Driver documentation also typically mentions this problem. For example, here's the doc for doing client-side param interpolation in the most popular MySQL driver for Golang: https://github.com/go-sql-driver/mysql#interpolateparams
It also explicitly detects if your initial connection settings attempt to use one of those charsets along with param interpolation, and throws an error if so: https://github.com/go-sql-driver/mysql/blob/21f789cd/dsn.go#...
> Couldn't one just save the extra round-trip with length-prefixed strings by sending the query together with the parameters in a single message?
AFAIK, no, not with the traditional MySQL binary protocol. The newer "X protocol" introduced in MySQL 5.7 does allow this, but it is not widely implemented in drivers.

[Question] Working with databases/storing data in Go applications.
However, you can use something like this https://github.com/go-reform/reform to help you with, I will call it automating the code writing. But I have always opted to one of the supported drivers and written a queries myself using for example this https://github.com/go-sql-driver/mysql.
