Using Google’s “multiple sign-in” feature is a great way to juggle between multiple Gmail accounts. But a common issue with using multiple Google accounts is being able to determine which is the default account, and it’s easy to get things mixed up with multiple logins. That’s what we’re looking to resolve here, by setting the proper account as the default Google account, regardless of how many other accounts are in use.
Following are the steps that needs to be taken care:-
Go to any Google site (google.com, gmail.com, etc) in a non-private browser window (this is so that a cookie can bet set).
Log out of any and all Google / Gmail accounts, this is done by clicking on your avatar icon in the upper right corner of a Google page and choosing “Sign Out” from the menu option.
Now go to Gmail.com, and log in with the account you want to set as the default or primary account – this is important, the first account you log into becomes the default when multiple sign ins are used.
Once you’re logged into the primary/default account, click on the avatar icon in the upper right corner of a Google page and choose “Add Account”.
Add the second, third, and any other Google accounts as necessary.
Vertical Scaling is the addition of extra resources to the servers in a network. For example, a business runs up against storage capacity limits, so they choose to add extra or larger hard drives to their existing servers. It is the old fashioned approach, and it tends to be significantly more expensive than the horizontal scaling we’re going to look at below. If a company expects to be vertically scaling their existing hardware, then that hardware has to be built with the possibility in mind. It has to have excess capacity, extra drive bays, and so on, that will end up sitting idle until the moment of expansion comes. Such hardware tends to be significantly more expensive than commodity hardware: hardware prices don’t scale linearly.
Vertical scaling is also fairly inefficient when it comes to resource reallocation. Because servers tend to be dedicated to particular tasks, it can be hard to reallocate the spare resources of a server to other, more pressing tasks. That’s why virtualization has become so popular.
Horizontal Scaling, on the other hand, involves adding more nodes to the system as it scales, rather than beefing up the existing nodes. This is by far the most popular scaling strategy in modern times. Google, Facebook, and other huge enterprises rely on using many nodes of relatively inexpensive commodity-class hardware, which they can add to and retask as the need arises. Because horizontal scaling is the growth method of choice for very large Internet enterprises, software has been developed that makes distributing file serving, databases, and virtualization across an expanding pool of nodes practical. For example, Google’s Spanner is a distributed database that is designed to scale at globally. The increasingly popular Hadoop software framework has horizontal scaling as a key design principle.
Google Drive is one such app that’s has integrated document-scanning and OCR capabilities. Snap a photo of a document and a PDF copy of the document will be saved to Google Drive. It will also use the power of Google’s servers to perform OCR on the documents, making it searchable in your Drive.
To do this, open the Drive app on your phone, open its menu, and tap Add New. Tap the Scan option in the list to scan and upload a document. Note that you could also add the Drive widget to your home screen and tap the camera icon on it to quickly open the Scan interface — this is useful if you frequently want to scan documents.
