Dear Customer,

I am Randy Jacops, the CEO of Idera, Inc. You likely saw the press announcement last month announcing Idera’s acquisition of Travis CI (hereafter, Travis). Here is a link to the announcement if you have not seen it: Idera, Inc. Acquires Travis CI GmbH for Continuous Integration Capabilities.

I’d like to welcome you to the Idera family and look forward to building on Travis’ history of market leading continuous integration products for software developers and testing professionals. I’m writing this letter to introduce Idera and explain why we are excited to acquire Travis.

Idera delivers B2B software productivity tools that allow technical users to do more with less, faster. The company's brands span three divisions—Database Tools, Developer Tools and Testing Tools—with products used and evangelized by millions of community members and more than 50,000 customers worldwide. Continuous integration accelerates software delivery, improves developer productivity, and enables technical innovation t

How to use asynchronous generators

The documentation 6.2.9.4. "Asynchronous generator-iterator methods" is phrased really ambiguously. To make matters worse, typing.AsyncGenerator is not specified fully correctly.

Here, I attempt to more clearly capture the actual interface contract, based on what I've read and observed. See also PEP 492 -- Coroutines with async and await syntax and PEP 525 -- Asynchronous Generators.

This might be useful to implement lower-level behaviors than you can with async for, like sending values into the generator function.

TSend = TypeVar('TSend', contravariant=True)

carlossless [09:50] So anyone used RxSwift? I’m wondering what are your thoughts and opinions vs RAC3.

carlossless [10:13] Yeah, I was looking for a more practical point of view but even so. RxSwift has UI bindings, it follows the haskell naming for most transformation and composition functions map, filter etc. rather than select, where.
