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.

I have done a full benchmark of a POST REST API on my computer: Node.js vs Fastify vs Express.js vs Deno vs Bun vs GO. Node.js is used WITH and WITHOUT clustering on 6-core I7 processor
https://github.com/just-js/just Is another for a V8 runtime, it really shows how well optimized it is. https://www.techempower.com/benchmarks/#section=data-r21

Bun v0.6.0 – Bun's new JavaScript bundler and minifier
i just tried recompiling v0.0.2 (https://github.com/just-js/just/releases/tag/0.0.2) of just-js and comparing it to current. for the completely static build on ubuntu 22.04 i see following:
0.0.2 (v8 v8.4.371.18) - file size: 15.2 MB, startup RSS: 8.4 MB

Is Scala to Java the same relationship as TypeScript has with ECMAScript?
Not at all. Javascript, as well as java compiled into the bytecode, but just incrementally and at the runtime. You cannot compile typescript into bytecode directly (at least it intend to be like that). You can even compile js to executable (https://github.com/just-js/just). So no, typescript transpiles to javascript, whereas scala compiles to bytecode, it's different things

A C++ web/application framework I have been building for the last 12yrs
Trust me, these guys are insane and go to really extreme levels and use optimization techniques which are not generally prevalent among the general programming fraternity. for eg, look at pico.v it is awesome and just-js is truly unbelievable, then there is faf, most of them combine low level programming trickery to reach those insane numbers. Also some of the code may not be useful in a production app but they actually extract the juice out of the metal at every instance. Memory optimizations, compiler optimizations, postgresql wire implmentations, rust black magic, these guys are really crazy and passionate.

Working with ListView in Windows Forms
Even those the old backend code to read from a database would work, the code was rewritten using Dapper. Had to add two column aliases in SQL SELECT statements and everything worked.

Import data from a database with Dapper and SpreadsheetLight to Excel in C#
In this article learn how to create Excel spreadsheet documents from reading data from two SQL-Server table from a modified version of Microsoft NorthWind database using NuGet package Dapper and SpreadSheetLight to create and populate the spreadsheet files.

Multiple Result Sets for SQL-Server (C#) including Dapper
Learn how to read reference table from SQL-Server using a single method. What is shown provides an efficient way to either use a connection, command objects to read data via a SqlDataReader for conventional work using methods from SqlClient and also Dapper which requires two lines of code to read data and one line of code to store data into list.

BREAKING!! NPM package ‘ua-parser-js’ with more than 7M weekly download is compromised
https://www.nuget.org/packages/Newtonsoft.Json/ https://www.nuget.org/packages/AutoMapper/ https://www.nuget.org/packages/Dapper/ https://www.nuget.org/packages/FluentValidation/ https://www.nuget.org/packages/FluentAssertions/ https://www.nuget.org/packages/NUnit/ https://www.nuget.org/packages/xunit/ https://www.nuget.org/packages/YamlDotNet/ https://www.nuget.org/packages/Moq/ That is simply not true. Mature c# projects purposely maintain no downstream dependencies and is they do, it's to a major reputable lib. See for yourself - these are staple third party packages commonly used. Anything dependency starting with System or NETStandard is Microsoft maintained.

How to Build a Blazor CRUD Application with Dapper
In this blog post, we are going to discuss how to bind the Syncfusion Blazor DataGrid with a database using Dapper and perform CRUD operations. To demonstrate this, we are going to create a bug tracker database table in MS SQL Server and perform CRUD operations in that table in a Blazor server-side application.

Requests per second 12 requests per second – Realistic Python web frameworks
Like there wouldn't be anything in between /s
There are "simple ORMs" that only map results of SQL queries to objects. They do not provide a magic query API - which is the source of most problems. I don't do Python, but for .NET there is Dapper https://github.com/StackExchange/Dapper, you can have a look what I mean. You write the SQL query, explicitly execute it, the library maps the results of that query into objects (it's C#, so you have to declare the class. In Python I'd imagine it would create the object for you)
-
Why would I even bother using Dapper?
To add some differences: EF tracks object state in an instance of a context, Dapper does not. Dapper is strictly for object mapping (taking the output of a query and mapping it onto an object). This makes Dapper far easier to implement, versus EF’s DbContext configuration. Due to the lack of tracking and slimmer wrapping, it’s also faster. Things get really great when you have multiple complex objects and multiple result sets. It takes a lot of boring boilerplate code out of your code.
