I am trying to use a parameterized path for a reference_docx in a Rmarkdown document with rmarkdown::word_document output format, in a similar way as e.g. is done here for the bibliography file (section Bibliograghy and Citation YAML options).

However, it seems like this feature does not work for the reference_docx option, as expressions passed to the arguments of the output format function (rmarkdown::word_document, or bookdown::word_document2 for that matter) are interpreted literally instead of evaluated. See e.g. this minimal reprex:

I have gone through below posts. Still I am unable to understand redirection uri concept.

https://www.baeldung.com/spring-webclient-oauth2

https://docs.spring.io/spring-security/site/docs/5.0.7.RELEASE/reference/html/oauth2login-advanced.html#oauth2login-advanced-redirection-endpoint

https://docs.spring.io/spring-security/site/docs/5.2.x/reference/html/oauth2.html#oauth2login-sample-redirect-uri

In identity server , we get our client application registered and for code grant type , we tell that this would be our redirect url i.e. https://someserver:port/

However, spring and other post suggests that to set redirect uri as {baseUrl}/login/oauth2/code/{registrationId}.

I am confused if i have set redirect uri as https://someserver:port/ in identity server , how {baseUrl}/login/oauth2/code/{registrationId} i.e. https://someserver:port/login/oauth2/code/{registrationId} will work. Should it not give invalid redirect uri?

Please correct my understanding.

I am fascinated by the approach used in this blog post to traverse a rose tree a.k.a multiway tree a.k.a n-ary tree using CPS.

Here is my code, with type annotations removed and names changed, which I did while trying to understand the technique:

I have enabled spring security 5 via Oauth2 code grant type in my UI application.

The base or context uri of UI application is "/" and the redirect URI is "BASE_URI/welcome/"

When i configure redirect URI template as "https://:/welcome/login/oauth2/code/myAuthProvider" it gives error as invalid redirect URI.

This error is coming because spring security is trying to find "/welcome/login/oauth2/code/myAuthProvider" instead of "/login/oauth2/code/myAuthProvider"

Below documentation suggests how to change default redirect uri. However, i need solution to tell spring security to ignore "/welcome/" in redirection endpoint. Please suggest any approach or guide me if my understanding is incorrect.

Using Workbox 4.3.1:

I've followed the advance recipe here: https://developers.google.com/web/tools/workbox/guides/advanced-recipes

It all works great if when the user refreshes the page, a new service worker is detected and it goes into waiting.

I'm doing that but also setting an interval to call "wb.update()" to check for new versions since people don't reload my PWA very often.

This works in that the serive worker goes into waiting, and when they click my update button, the "SKIP_WAITING" message successfully bumps it active, but the "controlling" hook doesn't work anymore for some reason, and so "window.location.reload()" doesn't work.

Any ideas? The advanced recipe doesn't mention anything about clients claim, but I do have workbox.core.clientsClaim() in my service worker.

Is there a canonical base-R method to determine if a function argument is an object name vice a literal/expression?

While NSE is typically discouraged, occasionally somebody has a good idea and wants to use it. The simplest use-case that I might justify as "convenient" is data.frame: if you include saved vectors, it will use the object name as the column name. (In fact, many classes seem to teach this as the best/only way to make frames.)

I want to solve the predicting house pricing problem (https://www.kaggle.com/c/house-prices-advanced-regression-techniques/data)

How could I transform string data into numerical data in Octave?

I am using a Workbox in my Angular app and I am checking for Updates every 15 min so I can inform the user if a new version has been deployed.

When an update has been found, the new Service Worker is installed but not activated since this when I can prompt the user to reload the page:

When OK is clicked, I can inform my SW to skip waiting, since he has this EventListener:

I'm working with NextJS and Workbox to create the PWAs and the offline support I need with this library: https://github.com/shadowwalker/next-pwa. There's an example of what I need in the repo above: an offline fallback. I don't need the app to work fully on offline mode, just a fallback page indicating that the connection is lost.

I read the workbox section about the comprehensive fallback:https://developers.google.com/web/tools/workbox/guides/advanced-recipes#comprehensive_fallbacks

There's a catchHandler which is triggered when any of the other routes fail to generate a response, but the problem is that I'm having huge trouble catching the XMLHttpRequests (XHR) errors.

When the request is sent by the client to an API for example, if there's no internet connection, I'd like to render a fallback page instead. The handler only servers the fallback page if the failing request is a "document", and since XHR requests are not documents, I just cannot handle them.
