Frontend/Backend Integration: Wait for a Google Cloud function to run and then return result

I am trying to create a tool that receives a user input on the front end, uses that input to run a Google Cloud function and then returns a link to the output, hosted on Google cloud as well.

How can you give updates that a process is being performed, and update the page when it is finished?

Best way to deal with lots of nested closures in Swift

I have some external SDK library that makes IO calls (either networking or database) in the form of blocks, like so:

SomeClass.doWork(success: {}, failure: {})

Now I need to chain about 60 different calls because we are working on data replication where each operation is distinct enough that it’s not the same, but the principle is there -> all of these take a success and a failure blocks.

What is the best way to organise this spaghetti:

let failureBlock: () -> Void = { // something

SomeClass.doWork(success: { [unowned self] in
   self.runChecks(success: {
       SomeOtherClass.somethingElse(success: { 
           SomeClass.doWork(success: { [unowned self] in
              self.doMore() ///... and on and on she goes
           }, failure: failureBlock)
       }, failure: failureBlock)
    }, failure: failureBlock)
}, failure: failureBlock)

mongodump and restore in single command

How to perform mongo DB dump and restore in a single command, by providing source and sink DB and collection name separately?

I understand we can do mongodump and then mongorestore but if I need to this on an intermediate machine, this will mean I will need to wait for mongodump to complete before I can start mongorestore manually again. Is there a way to do it in a single command?

How do remove the default storage pool from a libvirt hypervisor, so that even after libvirtd restarts there is NO storage pool

I want to remove the default storage pool from my virt-manager AND NOT HAVE IT COME BACK BY ITSELF, EVER. I can destroy it and undefine it all I want, but when i restart libvirtd (for me thats “sudo systemctl restart libvirtd” in an arch linux terminal window), and restart virt-manager, the default storage pool is back, just like Frankenstein.

I don’t want a storage pool of any kind. I simply want to move from the dual-boot I have now (arch linux and windows) to running the two OS simultaneously. I intend to provision two physical disk partitions on the host to be disks on the guest, and I can do this via the xml that defines the domain.

Or am i required to have a storage pool no matter what?

How do I apply a Statement in my bucket policy to all users in my account?

Setting the princable to “*” with “Effect”: “Allow”, would make it public and i don’t want that.

“arn:aws:iam::my account id:user/*” is showing as invalid.

currently im just listing all the users in the princable but thats not exactly very maintainable.

I can allow in the IAM policy attached to the users and then deny in the bucket policy useing NotPrincipal but I can see that getting a bit complex and it seems much more secure to white list than black list?

A 301 Redirect, or permanent redirect, is recommended when dealing with something similar to this one.

If you just want to hard redirect anything hitting to then a simple Redirect should do like so:

<VirtualHost *:443>
	Redirect 301 /

The above example is also something that you will want to write in a server config like httpd.conf but not in a .htaccess file somewhere on your site directory. It is also clumsy since your old site’s pages – e.g – will redirect only to which is the index page of the site.

So the other option would be Rewrite. It is also in case you don’t have root access to the server, and/or other sites that are not yours are sharing it as well. It would look like the following:

RewriteEngine on
RewriteCond %{HTTP_HOST} ^ [NC,OR]
RewriteCond %{HTTP_HOST} ^ [NC]
RewriteRule ^(.*)$$1 [L,R=301,NC]

The above considers whether the request is written with or without the www subdomain in it. The old links or pages will also get carried over to the new one.
