It will be great if Python can be ported to other platforms. The flexibility of Python is great for exploring things like new network structures, etc. But once you have decided most of the specifications, it's better to use something like C or Java to build a more strong code base (so a typo won't screw you up, LOL)
And I have to say, I'm really jealous of Python on machine learning stuff, where JVM is (almost) completely being ignored until people need a more robust way to develop and only find out the Java is a complete nightmare to do operator overloading and have to write something like "a = a.mul(b)"

As a JVM lover, I am jealous of the ability to call C code directly from CPython.
And yes, coroutine is powerful. I'm using kotlin coroutines and it's a huge (free) improvement of Java's native thread.
@npub1kpw…xzz4 co-routines can run on multiple threads, where the "tasks" can yield and the thread from a pool can switch to another "task" without suspension or something. At least kotlin coroutine can, and according to sdgathman, Python can do it too. That's the ultimate free boost you can get by just switching to another tech.
But if Python can do that, then my earlier hypothesis about switching to go will give your free boost is wrong

@npub1kpw…xzz4 oh.. my bad. I did a quick google search and found Python is quite different from JVM. On JVM, a thread is always a kernel thread. On Python, it might or might not be (StackOverflow told me this). So when I initially thought about GIL, I thought it would be act like a monitor lock on JVM, which cause a kernel thread to suspend and have a relatively huge penalty.
And after another goolge search, yes, I do mean statically typed and strongly typed, where you need to declare the type of a variable and cannot change it on the fly.

@npub1kpw…xzz4 ok, thanks, that's some updates to my knowledge base :ablobthinking:
Based on my experience on JVM, when I switched from JVM's native thread to Kotlin coroutines (which is based on threads but is able to share threads, so less thread suspension overall), I got a free performance boost. I assume go can achieve the similar thing. If so, I would say there is a free optimization without largely redesigning the algorithm.
Also, I always prefer strong typed languages when co-op with other developers. Python makes me panic when I don't know what the type of variable x :ablobgrimace:

@npub1kpw…xzz4 @npub1ukc…40jn Based on my limited knowledge of python, the multithreading part is pretty heavy, if I recall correctly, you need a new python process to start a new thread (sounds familiar with JVM :ablobthinking: ). And go is pretty good at multithreading (I mean user-mode threads). If not limited by the IO, I would assume a go implementation will speed up some of the process. Maybe also ease the load on developers, considering go offers some great built-in multithreading structures.

@npub1kpw…xzz4 @npub1ukc…40jn I do hear the matrix developers say there will be a go implementation to replace the slow and resource demanding python version. Is that still in alpha stage?
(As a jealous JVM lover, I don't trust Python 😂 )

I have encountered this a few times before (maybe one or two times?). It's rare, and I don't know how I triggered that.
The last time I had this issue was on my Android tablet, I switched from the browser to another app and then quickly switched back, then I got a lot of rate limit warning, and I do have to wait until I can fetch updates and post toot.
