1 You need to accept cookies

2 Use Selenium's explicit waits. To use them you will need to import:

You can either use the fig.cap argument to an R code chunk with knitr::include_graphics, or provide a caption through a markdown image link.

A minimal example:

You just have to add the class hide in the div.gameCard-tags. The rest works as expected:

Finally, I got to make the rollback functionality happen after every test.

I got that working when I saw a package called pytest-postgresql implementing it on itself. I just made my adjustments to make tests rollback the database data that I was working with. For that, I just had to implement this function on conftest.py:

Default repositories are deprecated.

Replace repositories *.ubuntu.com with old-releases.ubuntu.com in /etc/apt/sources.list with following (This is entire Dockerfile):

If somebody else SSH-ed into the same device (as a different user with different SSH keys), would they also be able to view the credentials

No, since, as the documentation mentions, the cache is accessible over a Unix domain socket, restricted to the current user by filesystem permissions.

compare vs. using git SSH key authentication security wise?

SSH keys means you are not typing a password.
To achieve the same with HTTPS, it is better to use a persistent cache, rather than a temporary one, where you need to type the password at each session.

The latest one would be GCM-core: Git Credential Manager Core.
It needs to be installed, but once git config credential.helper is set to manager-core, it will store the password (for a given URL) in a secure local vault, using libscret to communicates with the "Secret Service" using D-Bus (gnome-keyring and ksecretservice are both implementations of a Secret Service.)

What exactly happens when a child process (created by child_process.fork()) in Node sends a message to its parent (process.send()) before the parent has an event handler for the message (child.on("message",...))? (It seems, at least, like there must be some kind of buffer.)

First off, the fact that a message arrived from another process goes into the nodejs event queue. It won't be processed until the current nodejs code finishes whatever it was doing and returns control back to the event loop so that it can process the next event in the event queue. If that moment arrives before there is any listener for that incoming event, then it is just received and then thrown away. The message arrives, the code looks to call any registered event handlers and if there are none, then it's done. It's the same as if you call eventEmitter.emit("someMsg", data) and there are no listeners for "someMsg". But, read on, there is hope for your specific situation.

In particular, I'm faced with what seems like an unavoidable race condition - I cannot install a message handler on a child process until after I've finished the call to fork, but the child could potentially send me (the parent) a message right away. What guarantee do I have that, assuming a particularly horrible interleaving of OS processes, I will receive all messages sent by my child?

Fortunately, due to the single-threaded, event-driven nature of nodejs, this is not a problem. You can install the message handler before there's any chance of the message arriving and being processed. This is because even though the child may be started up and may be running independently using other CPUs or interleaved with your process, the single-threaded nature and the event driven architecture help you solve this problem.

If you do something like this:

There are issues with animations using svg charts, such as BarChart is animated when you press on the button in your code, but LineChart isn't. I suggest using different library if you need an animation specifically for LineChart. Also, you can look at this example of D3 and ART implementation.

In the insert expression, you are telling the XQuery engine to insert the node before //musica. However, is the root node of the document, so inserting a node before it would cause the XML file to be non-well-formed. I would expect the engine to throw an error.

If your goal is to insert the element into the element, you would use the following expression:
