fastify-sensible now part of npm init fastify

I have noticed that a few weeks ago, fastify-sensible is now part of the auto-generated content from $ npm init fastify, and loaded in the plugins/sensible.js file. This conflicts with some of the content of the course. If you follow some of the given instructions and you try to register it in the app.js file, the application won't start - you will get a FastifyError [Error]: The decorator 'httpErrors' has already been added!, because you are registering it twice:

one in the autogenerated plugins/sensible.js file,
and the second in the app.js.

This is the case, at least, of the section 5 (Implementing a RESTful JSON GET with Fastify).

For anyone getting this issue, the fix is simple:

Either you remove the plugin/sensible.js file
Either you don't register fastify-sensible in the app.js file

Re: 42.9. LABS 1 Exercise 42.1: Security and Mount Options

if you actually typed what you said in your email you are missing a "/". it sounds like you simply copied to make a new file named "mountpoint" , it does not say mountpoint is a directory. So if you switch directories to somewhere else it cannot work. In other words it should be:

mkdir mountpoint
cp /bin/ls mountpoint
mountpoint/ls

But if you go somewhere else you have to give the full path as in:

cd /tmp
/home/student/mountpoint/ls

or wherever you put it.

Re: Hi Everyone! Anybody knows the proceedings to install the Cheese Webcam on CentOS 7/8?

Hi @Helio,

That sounds more like a VirtualBox question than Linux related. I think you can take a look to the VirtualBox documentation, about "webcam passthrough":

https://www.virtualbox.org/manual/UserManual.html#webcam-passthrough

==> 9.5.1. Using a Host Webcam in the Guest

Re: How to handle different behaviour of Dynamic Evaluation on CentOS 8 and Windows?

hi @zorawar that doesn't seem right at all - however it shouldn't affect any of the material either way

Hi @zorawar,
