Synchronous sockets status?
by Joe Marshall April 10, 2022

April 10, 2022

Hi all, Is anyone working on adding synchronous sockets support in pyodide yet? If not, does anyone have opinions on how it should be done? I can see with support for shared memory across browsers now it would be easy enough to do it with that in JavaScript with a web worker and atomics.wait. The obvious alternative would be to make threading and synchronisation primitives work in python and do fetch calls in a thread. Has anyone built threaded pyodide yet? Does webassembly threading work in WebKit now? Any ideas how that would interact with JavaScript? Threading is obviously a heavier weight thing, but on the other hand I guess it would fix lots of problems in a way that a dedicated JavaScript solution wouldn't.

Hi all, I am a CEO, and long-time Python developer, of Trading Strategy - https://tradingstrategy.ai We are a new startup that builds open-source algorithmic trading solutions on Python. We offer both strategy backtesting and live trade execution on cryptocurrency markets. Currently, we have finished our seed round and the company is still in the product Minimum Viable Product build phase. For this, I would like to research the opportunity to run our client Python library directly in a web browser using Pyodide / JupyterLite. This would make it much easier for quant finance people, who are often not hardcore software developers, to access the beauty of Python-based data research. I would like to see if there are people in the Pyodide community who would like to work with us. The work would be subcontracted to a Gibraltar-based company and consist of creating a static HTML proof-of-concept example. I am happy to work with anyone from students to professional Python consultants. If anyone is interested in this sort of gig please contact me mikko(a)tradingstrategy.ai All our related codebase is open source. More accurate task description: https://github.com/tradingstrategy-ai/client/issues/11 Here is our Python client: https://github.com/tradingstrategy-ai/client/ An example Hello World notebook: https://tradingstrategy.ai/docs/programming/examples/getting-started.html More information about our product and vision: https://tradingstrategy.ai/blog/announcing-trading-strategy-protocol Some earlier work we have done in open-source space: https://tradingstrategy.ai/blog/world-fastest-token-search https://www.timescale.com/blog/how-trading-strategy-built-a-data-stack-for-… Br, Mikko

Pyodide sprint at PyCon US
by Roman Yurchak April 1, 2022

April 1, 2022

Hello, we are organizing a Pyodide development sprint at PyCon US 2022 conference (https://us.pycon.org/2022/). This sprint will take place *May 2 to 5, 2022 in Salt Lake City, US*. It will happen 2 days during the conference sprints and 2 days after the conference. This will be an in person event, however remote participants are also welcome. This is an event where existing and new contributors can work on the project, on topics ranging from addressing existing issues, implementing new features, exploring new ideas, or adapting your existing projects to work with Pyodide. If you are interested in participating, please add your name to the list in https://github.com/pyodide/pyodide/wiki/PyCon2022-sprint Due to PyCon2022 rules this year, all those that participate in sprints in person must be registered to attend the conference, and attendees to the conference must provide proof of vaccination status. From what I was told, there can be an exception for people local to Salt Lake City regarding the conference registration requirement (see conference announcements). For information, PyCon US has travel grants, so those who might otherwise not be able to attend can. The deadline to apply is February 11, 2022. Otherwise, if you have any questions about this sprint please let me know, Best, -- Roman Yurchak
