FrameworkBenchmarks VS Mastodon

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.

Oh, TIL about https://mastodon.social/ (https://joinmastodon.org/)

Looks like what you describe, doesn't it?

Interestingly there is some discussion for Mastodon with people asking the limit to be smaller, which raises the question as to the purpose of alt text, and how to properly handle larger text lengths in screen reader programs.

Through the Fast Forward program, we give free services and support to open source projects and the nonprofits that support them. We support many of the world’s top programming languages (like Python, Rust, Ruby, and the wonderful Scratch), foundational technologies (cURL, the Linux kernel, Kubernetes, OpenStreetMap), and projects that make the internet better and more fun for everyone (Inkscape, Mastodon, Electronic Frontier Foundation, Terms of Service; Didn’t Read).

Mastodon DMs have absolutely no privacy: https://github.com/mastodon/mastodon/issues/18079

For a decentralized protocol doing things right is much more important than doing things fast, it is very difficult (and in a lot of cases impossible) to break backwards compatibility.

Postmortem on what happened here: https://news.ycombinator.com/edit?id=39305884

The v1 API of Mastodon limits the size of the tree that it will expand for users who are not logged into the server: https://github.com/mastodon/mastodon/blob/main/app/controllers/api/v1/statuses_controller.rb . I am guessing that this or some similar limit applies to threads being returned to unauthenticated users of the web UI. It just arbitrarily stops expanding the replies at some point, including the main thread from the OP.

If a thread is truncated, users expect it to expand automatically and autoscroll when you hit the bottom. In my desktop browser, that does not occur, and there is no indication that there is more to see. This is the situation of the web interface as of Mastodon version 4.2.5.

The issue is very sensitive to observer conditions. If you are logged into the server, the behavior is different. If you use a Mastodon app instead of the web, the behavior might be different. As the tree expands, the cutoffs become different. If you look at the thread on a different Mastodon server, the tree is different because every server has its own view of the Fediverse.

HN needs a best practice for linking to Mastodon threads in a way that provides a consistent experience to HN readers. The average Mastodon server would be crushed by hundreds of HN readers grabbing the entirety of a huge thread all at once, so this might involve some thread-unroll-and-cache service. I tried https://mastoreader.io/ but it did not solve the problem.

Alternately, we push changes into the Mastodon web UI to warn users when they need to click to see more and assume that people will get used to the navigation.

Suggestions?

Fixed in Mastodon v4.2.5 https://github.com/mastodon/mastodon/releases/tag/v4.2.5

>You can defeat the Affero clause by putting the software behind a proxy, for example

Could someone elaborate on this? This is NOT my understanding of the license, and it seems absurd considering e.g. Mastodon is AGPL but the standard install requires a reverse proxy[1]. If using a proxy defeats Affero, why would the Mastodon team do this? Are they stupid?
