async vs. sync depends exactly on what you are doing in what context. If this is in a network service, you need async. For a command line utility, sync is the appropriate paradigm in most simple cases, but just knee-jerk saying "async is better" is not correct. My snippet is based on the OP snippet for context.

session = ActionDispatch::Integration::Session.new(Rails.application) response = session.post("/mypath", my_params: "go_here")

I used the above to test what happens to the user if a POST happens in another session (via WebSockets), so a form wouldn't cut it.

An extensible plugin architecture allows for customizing your workflow or even making Yarn a package manager for non-JavaScript projects.

apart from [Websockets], which is unnecessarily complex for non-browser applications

Thanks, this was just what I was looking for! This is a perfect appropriate use of instance_eval. I do not understand the nay-sayers. If you already have your array in a variable, then sure, a.reduce(:+) / a.size.to_f is pretty reasonable. But if you want to "in line" find the mean of an array literal or an array that is returned from a function/expression — without duplicating the entire expression ([0,4,8].reduce(:+) / [0,4,8].length.to_f, for example, is abhorrent) or being required to assign to a local, then instance_eval option is a beautiful, elegant, idiomatic solution!!

With Stack Overflow for Teams being a flexible platform, we’ve seen customers use it for a wide variety of use cases: A platform to help onboard new employees A self-serve help center to reduce support tickets Collaboration and documentation to drive innersource initiatives Breaking down silos and driving org wide transformation like cloud migration efforts A direct customer support platform Enable people who are working towards a common goal, whether a startup or a side project, to develop a collective knowledge base

What produces that text, and what do you want to use it for?

If it's a list of actual pathnames, just replacing spaces by newlines may obviously mangle pathnames that contain embedded spaces, such as /User/myself/VirtualBox VMs/.

This is a great application for using route constraints.

Application: 3-D Shape RegistrationAn important problem in model-based recognition is to find the transformation of a set of datapoints that yields the best match of these points against a shape model. The process is oftenreferred to asdata registration. The data points are typically measured on a real object by rangesensors, touch sensors, etc., and given in Cartesian coordinates. The quality of a match is oftendescribed as the total squared distance from the data pointsto the model. When multiple shapemodels are possible, the one that results in the least total distance is then recognized as the shapeof the object.Quaternions are very effective in solving the above least-squares-based registration problem.

So, the sad conclusion is: all problems must be resolved individually depending on a specific usage context. There’s no silver bullet to resolve all ZeroDivisionErrors once and for all. And again, I am not even covering complex IO flows with retry policies and expotential timeouts.

Like all best practices, I think the way you will resolve a problem will depend of the application you are doing.

Honeybadger isn't a single page app, and it probably won't ever be. SPAs just don't make sense for our technical requirements.

Looks like the problem is that debounce defaults to waiting for 0 ms ... which is completely useless!
