But to go deeper to .NET/CLR architecture is important too. Try to understand how it works inside. Use the source, Luke! https://source.dot.net/ https://referencesource.microsoft.com/ This source code vaults is not completed then try JetBrains dotPeek tool to look at any assembly source code.

(https://github.com/Microsoft/referencesource/blob/master/System.ServiceModel/System/ServiceModel/MessageSecurityVersion.cs; scroll down to inner classes)

List is an IList/IReadOnlyList; these interfaces do nothing that couldn't be done right inside the file itself.

Instead we have to go diving through the IList, which implements ICollection, which implements IEnumerable, which implements IEnumerable (again). Just because each interface is composed of another interface, doesn't mean you aren't using inheritance. You are effectively creating a custom inheritance tree through willy-nilly composition.

It is gratuitous to make this chain so deep, when the underlying code is just a handful of lines.

The doc-strings are unnecessary. It's self-evident what most of the code does if you read it.

        // Returns an enumerator for this list with the given

The whole .net framework source code is online.

.net itself has arbitrary interfaces, ex https://github.com/microsoft/referencesource/blob/master/mscorlib/system/action.cs

Assuming if you are new to C# - start coding! And start reading https://learn.microsoft.com/en-us/dotnet/csharp/tour-of-csha...

If you are not new to C#, start building an application end-to-end/a classic n-tier application, right from using a database, Entity Framework, WebAPI, DTO, AutoMapper, and a front-end (your choice - Angular/React/Vue with TypeScript or better yet - Blazor).

You will not only understand & use dependency injection, reflection, LINQ, multi-threaded programming, generic programming, source-code generation, unit-testing - and much much more in a practical/real-world usage.

Peruse https://referencesource.microsoft.com/ once in a while.

Follow various team members of .NET Framework, C# team and the like on various social-media. https://mobile.twitter.com/i/lists/120961876

I am sure there will be who agree / disagree with the above approach and will provide more viewpoints for you to consider.

Enjoy - and strap yourself for an amazing journey or roller-coaster ride, however you want to call it!

Maybe from the source of FtpWebRequest it is possible to track what the default behaviour is.

The class is just a very limited dictionary, a library will be the same or better.

Neat. Thanks for sharing!

Interestingly, may-minihttp is faring very well in the TechEmpower benchmark [1], for whatever those benchmarks are worth. The code is also surprisingly straightforward [2].

ntex was formed after a schism in actix-web and Rust safety/unsafety, with ntex allowing more unsafe code for better performance.

ntex is at the top of the TechEmpower benchmarks, although those benchmarks are not apples-to-apples since each uses its own tricks: https://www.techempower.com/benchmarks/#hw=ph&test=fortune&s...

Ruby is slow. Very slow. How much you may ask? https://www.techempower.com/benchmarks/#hw=ph&test=fortune&s... fastest Ruby entry is at 272th place. Sure, top entries tend to have questionable benchmark-golfing implementations, but it gives you a good primer on the overhead imposed by Ruby.

It is also not early 00s anymore, when you pick an interpreted language, you are not getting "better productivity and tooling". In fact, most interpreted languages lag behind other major languages significantly in the form of JS/TS, Python and Ruby suffering from different woes when it comes to package management and publishing. I would say only TS/JS manages to stand apart with being tolerable, and Python sometimes too by a virtue of its popularity and the amount of information out there whenever you need to troubleshoot.

If you liked Go but felt it being a too verbose to your liking, give .NET a try. I am advocating for it here on HN mostly for fun but it is, in fact, highly underappreciated, considered unsexy and boring while it's anything but after a complete change of trajectory in the last 3-5 years. It is actually the* stack people secretly want but simply don't know about because it is bundled together with Java in the public perception.

*productive CLI tooling, high performance, works well in a really wide range of workloads from low to high level, by far the best ORM across all languages and back-end framework that is easier to work with than Node.JS while consuming 0.1x resources

Although that seems to have improved in recent years.

RoR and whatever C++ based web backend there is count as a valid comparison in my book. But comparing the languages itself is maybe a bit off.

On a side note, you can actually compare their performance here if you’re really curious. But take it with a grain of salt since these are synthetic benchmarks.

Most benchmarks you'll find essentially have someone's thumb on the scale (intentionally or unintentionally). Most people won't know the different languages well enough to create comparable implementations and if you let different people create the implementations, cheating happens. The TechEmpower benchmarks aren't bad, but many implementations put their thumb on the scale (https://www.techempower.com/benchmarks). For example, a lot of the Go implementations avoid the GC by pre-allocating/reusing structs or allocate arrays knowing how big they need to be in advance (despite that being against the rules). At some point, it becomes "how many features have you turned off." Some Go http routers (like fasthttp and those built off it like Atreugo and Fiber) aren't actually correct and a lot of people in the Go community discourage their use, but they certainly top the benchmarks. Gin and Echo are usually the ones that are well-respected in the Go community.

There is certainly a lot of speculation in Techempower benchmarks and top entries can utilize questionable techniques like simply writing a byte array literal to output stream instead of constructing a response, or (in the past) DB query coalescing to work around inherent limitations of the DB in case of Fortunes or DB quries.

And yet, the fastest Ruby entry is at 274th place while Rails is at 427th.

oh what machine? with how many workers? doing what?

search for "node" on this page: https://www.techempower.com/benchmarks/#section=data-r21

JustJS would like a word https://www.techempower.com/benchmarks/#section=data-r20&tes...

In terms of RPS, this web service is more-or-less the fortunes benchmark in the techempower benchmarks, once the data hits the cache: https://www.techempower.com/benchmarks/#section=data-r21

Or, at least, they would be after applying optimizations to them.

In short, both of these would serve more rps than you will likely ever need on even the lowest end virtual machines. The underlying API provider will probably cut you off from querying them before you run out of RPS.
