The camera image optimization AI algorithm is mainly used in the following camera features: Super Moon, AI Camera, Document Mode, Front Portrait Mode with Background Blurring, and Beautify.

I am wondering if the AI enhancement should be opt-in rather than the default and saving the original as well. Even if you want AI enhancement, future models are likely to be better.

Julia is actually quite nice for this. If you prefer a python-like approach consider Triton from openai, numba (https://numba.pydata.org/) or CuTe DSL from Nvidia.

I use the Eumetsat FCI (Flexible Combined Imager) full disc images on board of geostationary satellite MTG centered at 0 degree longitude. A single image (distributed as netcdf file) is pretty large in fact much larger than my screen resolution. If you are interested, the Julia code for downloading and creating the PNG image is here:

https://codeberg.org/Alexander-Barth/FCI-MTG-0

While doing that, I learned that it is not so trivial to produce a true colour RGB image from these FCI [1]. I think there is also a WMS server for rendered images but I don't have the link on my phone.

I think this is quite similar to julia's handling of a struct. An array of mutable structs is just an array of pointers, where every pointer directs to the underlying structure. However with an array of structs (immutable is the default), there is no such indirection. The value of all fields are stored as array element (unless you have an array of heterogeneous elements).

If you want to change an element of such an array you need to create a new immutable struct which in practice it is quite fast, but a bit verbose to write.

I did not know about EuroLLM. I had a look to the paper (https://arxiv.org/abs/2602.05879) describing it:

Specifically, we discard documents shorter than 200 characters (Xue et al., 2021a), and any page containing the phrase “lorem ipsum,” the word “javascript,” or curly brackets (Raffel et al., 2023)....

It is quite surprising/funny to see all documents with javascript removed.

Are you using this code for Julia?

https://github.com/JuliaParallel/rodinia/tree/master/julia_m...

It was touched 9 years ago, but maybe you have ported it to current standards. I don't think we had multithreading at that time, only multiprocessing.

Is your Julia implementations available somewhere? (Sorry if it is in your paper but I missed it). I vaguely remembered in the past that working with threads leaded to some additional allocations (compared to the serial code). Maybe this is also biting us here?

For the datasets, I tried to access (like the full disc image in visible wavelength, MTG 0 degree), it is sufficient to register at eumetsat to get a username and password. The eumdac python tool is probably the easiest way to access the data:

https://pypi.org/project/eumdac/

(If you do not want to use python, the --debug option is quite useful to see exactly the request made. The output is either some JSON metadata or a large zip with the netcdf data)
