I've written a FIX engine in asyncio Python.

@pdgjones Hypercorn is my go to server.

[Rob Blackbourn @robblackbourn]

@__xuorig__ I like a protocol that includes subscriptions.

@Gideon63 @oraclebase Can I INSERT myself INTO this conversation?

[Rob Blackbourn @robblackbourn]

@claviska @javascriptd I’d also like the base language to be WASM, and JavaScript a supported language rather than the only one.

[Rob Blackbourn @robblackbourn]

@claviska @javascriptd Operator overloading. It’s a TC though, so no bonus points.

[Rob Blackbourn @robblackbourn]

@senkorasic Depending on your use case it’s worth climbing the async learning curve. Maybe you could post some examples of the problems you’ve had?

[Rob Blackbourn @robblackbourn]

@allenholub This was my proudest moment. I handed over some code to a (really smart!) junior dev. He looked at it for 30 seconds and said “there’s a much better way to do that”.

@kellabyte I’ve been using vs code and the dotnet cli. I’ve also got parallels installed with a windows vm for the framework stuff that only works on windows.

[Rob Blackbourn @robblackbourn]

I've written a Python client for Windows .Net NegotiateStream. Repo: https://t.co/zFzaOrAkYy, blog post: https://t.co/G4HaOdZQL4

@jonnykim Now I feel stupid :P Your code powers all my web servers. I use it literally every day. Maybe it’s better to use letters or acronyms when naming things (‘C’ or ‘REST’). They don’t carry baggage.

[Rob Blackbourn @robblackbourn]

@jonnykim I find it useful. I find the query language more powerful than REST. More importantly (for me) it provides a single interface that supports both one off (queries and mutations) and subscriptions.

[Rob Blackbourn @robblackbourn]

@jonnykim I see. I guess graphql looks like some kind of SQL,giving the impression it’s actually a database. It’s not really the fault of graphql though?

[Rob Blackbourn @robblackbourn]

That should be start_tls 🤪

[Rob Blackbourn @robblackbourn]

Python 3.11 has start_Ltd on Streamwriter. It works a treat. Now I can get http proxies working!

I’m on Mastodon as “rtb”

@pdgjones I just did the sort like the PR suggested and the dealock went away. See line 91 of https://t.co/Nkj3WnUBUT

@pdgjones

When adding my framework to [FrameworkBenchmarks](https://t.co/eMV9e8eQiJ) I notice quart (+ everything) fails. See the pull request for bareASGI or search issues for deadlock, re: updates/sort.
