I will attempt to drive sglang, I will try to speak to them next week - it's possible they may just not want to support Windows full stop (nginx was a case of this historically, they accepted PRs to build it, and allowed community
builds, but wouldn't support it officially with builds).
For temporalio, is cryptography shipping wheels now? As per Mayank's email, the work is already done, but it relies on cryptography to build. Therefore, I can't proceed until the upstream blocker is resolved.
follow up: NV works on cuda-python wheels and cuda-bindings. Current ETA is mid Aug.

Good day Anthony and everyone.
-
sglang is indeed even Linux only, no macos options. Which is might be a good win for us if we can make the support happen.
@Anthony Roberts do you see how we can reach them in DM? Can you drive this?
-
tree-sitter-languages, pyiceberg marked your findings in our tracker.
-
cuda-bindings I still didn't get the response from NV. They may be in a on fire situation, I see the signals about the potential delay of CUDA SDK public availability.

temporalio
@Omair Javaid do you guys aligned on this with
@Anthony Roberts ?

@Anthony Roberts please let me know if I missed something regardless the previous list of work you had, any other blockers you have? Feel free to
nudge me more frequent.

Thanks for investigation, I’ve sent the email to NV about cuda-bindings.

Hi All,
Regarding these:
sglang:
I suspect we'd need to reach out to the developers directly via the contact email address, to see why they have ignored the PR. I suspect they don't want the maintenance overhead of Windows, too. If x64 Windows
is also missing, I suspect this could be a decent candidate to argue doesn't need porting.
tree-sitter-languages:
pyiceberg:
Blocked on pyarrow
cuda-bindings:
We'll need to wait for the public CUDA SDK for this one, unless we're happy to use pre-release versions and not commit anything until public ones are out - are NV already working on this themselves, is it worth
checking?
temporalio:
Worth an investigation into the build failures Omair is seeing, and what is causing them. I'll try to look into this one, assuming Omair hasn't yet.
clickhouse-connect:
Looks like Omair's issue spurred them into doing it, no action is required from us
zopfli:
Same thing, they have also done the work for the wheel to be released
Thanks,
Anthony

Happy weekend everyone.

Anthony, you might be interested in that since nobody took it yet for enablement. Let me know if you start something from this list.
