Cannot add Calendar Resource to My Calendars

I have a G Suite Meeting Room and I want to manage its calendar. I’m following the instructions on this page to add a Calendar Resource to “My Calendars”, however the section My Calendars (capital C) and referenced “+” button in Step 2 below is not present.

Note: This question is specifically to add the calendar to “My calendars” so it can be managed, not to “Other calendars” where it cannot be managed or edited.

What am I missing to complete these instructions?

Here’s the instructions:


I have the following pre-requisites:

  • “administrator account with Calendar and Super Admin privileges”
  • “a calendar resource (such as a meeting room) for your organization” – resource with “Calendar-based room release” set to “On” and “Type” set to “Conference Room”


Here’s the screenshot from my user with the required “administrator account with Calendar and Super Admin privileges”. There’s no My Calendars (capital C) or “+” as specified in Step 2 above, but My calendars (lowercase C) does exist without a “+”.

Here are the steps:

Resource recommendations for Shopify Theme Development

I am currently using a paid theme for my Shopify website. However, I want to build a theme of my own so that I can customize it entirely as per my need. I am well-versed with the Shopify coding language. Are there any books/courses that I should read before starting theme development? (I already have done the Udemy and other courses available). I need a book/course that covers coding from scratch and has in-depth info about everything related to Shopify code.

AWS S3 resource access control through IAM permissions or bucket policies?

The way we create buckets in our org and ensure sane ACLs around it is by providing an automated tool (that internally uses Terraform) to provision an S3 bucket. So say when a user requests for a new bucket, named testBucket we create a bucket named testBucket and also create an IAM user by the name testBucket-user. The automation ensures that the testBucket-user‘s policies are such that the only allowed actions to this user are :

"s3:ListBucket", "s3:PutObject", "s3:GetObject" 

and the only allowed resource on which the above actions are allowed is the testBucket bucket.

Similarly, the automation also ensures that the automation puts bucket policies to ensure that the only actions allowed on it are the above 3 actions are the only ones allowed on it and only by the user testBucket-user

However, on demand (& if business justified) we do make changes to the created bucket policies as and when needed). So recently there was one such requirement, where a certain bucket needed to have a folder in it that was meant to hold all publicly intended images.

Now there were 2 options we had in order to provision to above requirement:

  1. Modify the bucket policy to allow principal:* for the folder in the bucket thus allowing all objects in that folder in the bucket to be by default public.
  2. To modify and give PutObjectACL permissions to the IAM user that has access to that bucket and let the dev manage which objects in the folder can be or can not be public.

As the security team we were more convinced of the first option just because it looked more logical. The problem with the first option however was the fact that now any object (publicly intended or even otherwise) would be by default public.

I wonder what does the community think here around it? AWS/IAM experts, what would be your choice of the two options above ?

What is the purpose of a requesting a non existent resource the site for Natwest Online Banking (a UK based bank) makes two requests to non existent resources. For example:

enter image description here

What is the purpose of this? Is it some kind of webapp security hardening? It seems the port numbers and image numbers change but the ip addresses (external and loopback) do not.

Typescript, CRUD Applications, and the generation of resource identifiers

I am currently trying a create a fairly simple, declarative RESTful CRUD framework, whereby I can define a resource type, and have both the API endpoint created, as well as the the functions to Create/Read/Update/Delete the declared resource.

ie. the usage would look a little like this:

interface Student {      name: string;       dob: Date;  }     const {fetchFunctions, initApp} = createContract<Student>(app, "/students");   //Serverside:  const app = express();  initApp(app);   //Clientside{   //OK.     name: "bob",     dob: "11/11/1911" });{   //Type error, because dob isn't included.      name: "Bob" });   const student = await fetchFunctions.get("111");  console.log(; //OK.  console.log(; //Type error, because Student doesn't have foo.  

Where I’m running into an issue is around the generation of IDs, and whether to include them in the resource object itself.

ie. Say I have done GET /students, to get a list of students, then I have to return the ID of the resources somewhere otherwise I am going to have no way to update them.

So either, I could put the ID on the resource:

[    {       id: "123",        name: "Bob",        dob: "11/11/1911",     },     {       id: "234",        name: "Alice",        dob: "12/12/1912",     } ] 

Or on some ‘Resource Wrappers’

[    {      id: "123",       data: {        name: "Bob",         dob: "11/11/1911",       }    },     {      id: "234",       data: {        name: "Alice",         dob: "12/12/1912",       }    } ] 

(Is this even RESTful? , and really, it’s not even different data).

The problem then, is I have to add the ID to the Student interface, and if I want to POST a student (without the ID), then I have to make it optional, and that starts getting messy, (ie. warnings about a possible null id everwhere).

Another solution is that I have two interfaces one Student and one NotYetCreatedStudent that doesn’t have an ID, and I POST the latter instead. This seems kind of tidy in a sense – but I don’t really like the ID of having to create two interfaces for every resource, having a whole second generic type on my functions etc.

This popular Stack Overflow question addresses the difference between POST and PUT, and basically the consensus seems to be that for creating a new resource, you do either:

POST /resource 


PUT /resource/123 

So maybe instead, then I could just not do ‘POST without ID to create a resource’ and instead do ‘generate a UUID on the client side and PUT with ID’ – which is seeming like the simplest solution.

Is there something I’m misunderstanding about RESTful APIs here that would help me solve this problem?

How to authorize access to a resource when requested with CORS and validate the origin?

I’ll try to make the explanation simple and to the point (keyword try). And if that’s not sufficient, then maybe I can expand on the question.

Imagine two sites: and I only have direct control over ultimately wants access to The idea here is the resource should be protected; secured.

I also cannot validate user credentials for authentication (i.e. username, password). I don’t have access to their user store. Ultimately, above all else, my priority is ensuring that is the identity of the resource requester.

My first thought was having issue a CORS request to for authorization and send back a token. Token expiry is small (<5 seconds). I check that the request is POST, validate the origin header and the referrer, if it exists. If no origin header is passed, authorization fails. User then passes back token with standard POST request to

The problem is this is a very bad authorization scheme. Origin header is resistant to spoofing but it absolutely can be spoofed. Referrer is even easier to bypass. wants to keep effort minimal, which probably means it’s up to me to code their piece because I don’t know if there’s a simple solution here. They are open to CORS request.

My question is how can I secure the resource on my site in a CORS request and ensure the identity of the client is, knowing the origin header can be spoofed?

Is there some way I can possibly leverage, i.e. aJSON Web Token (JWT) using asymmetric cryptography in order to prove the identity of the requester is, even if the origin header is compromised? If so, who would generate the JWT, me or

Is it recommended to send an authentication request to the Resource Owner (by the Authorization Server) if it already has an active session?

In OAuth 2.0 Authorization Code Flow (Grant Type), is it recommended (or is it maybe even a best practice) to send an authentication request (e.g. a login-request form) to the Resource Owner (by the Authorization Server), even if the Resource Owner has already an active session on the Authorization Server, when obtaining an Authorization Code for the first time for a certain Client?

In other words, is it recommended to kill/destroy a currently active session first, if there’s one? Or is it not important at all?
