buffer function is no longer available for String ?

You can access underlying pointer using undocumented methods _as_ptr() or _steal_ptr(). They work a bit strangely. I feel like due to lifetimes. So, you can play with them but I wouldn't count on them. Let's see what new release of Mojo in 2024 will bring.

Owned convention does not destroy variable after transferring ownership

Thank you for the answer. I will wait for the next update and as soon as it is published I will re-check this behaviour. Very excited to finilize exercises for value ownership and semantics. Just need them to get a bit more stable.

I filled a bug report on Mojo repository - https://github.com/modularml/mojo/issues/1604. The behaviour seems unusual to me, so either we can include more clarification in the docs or indeed it is a bug.

Are Type Hints Still Possible in Mojo?

Types in Python are only hints (hence "type hints" name), effectively Python interpreter ignores them. If you add types in Python you can still put any value you want to the function. Python will happily run it. Could you explain please about what you are trying to accomplish by using Python type hints in Mojo? Def function in Mojo supports types. You can specify them the same way you do in Python, but using types available in Mojo. The only difference is that Mojo will actually respect types. Example:

def func():
    def func2(x: Int):
        return x + 2
    return func2(3)


def main():
    print(func())

def func():
    def func2(x: Int):
        return x + 2
    return func2(3)


def main():
    print(func())

It will output "5".

SIMD produces weird results without print statement at the end

Anyway. That is quite interesting. Thank you for the help.

So by using _ = a I force compiler to provide a visibility for my tensor after vectorize?

_ = b also works. _ = c doesn't 🙂

What do you mean by simd_load inside the function? Should it still display a correct results after vectorize? But I see where you are pointing. Cause in all examples provided by Modular they returned from function at this point.

SIMD produces weird results without print statement at the end

I see. Surprisingly, my other SIMD implementation for euclidian distance (from Modular blog) is working fine. Maybe I am missing something. When I will have time, I will double check code and maybe look at assembly

Hmm. Interesting. Try to change size to multiple of 4, like 16?

I have M1, so it gives nelts = 2. Indexes provided by vectorize look fine. 0 2 4 6 8

To make it work, I uncommeted last print print(a.simd_load[nelts](0))

External Python dependencies and Mojo binaries

You can validate yourself by deleting a Python package with pip and trying to see if the same Mojo binary will work.

External Python dependencies and Mojo binaries

They will need Python with the same packages. To interface with Python, Mojo runs and communicates with CPython

mojo and distributed system

There is Mojo implementation of redis - https://github.com/igorgue/firedis. You can check bindings for system calls needed for networking. But yeah language is not mature and a lot of things could change.

memory leak with DynamicVector

Not familiar with details but shouldn't vector be freed after each outer loop? Or at least re-used?
