The thing is; you can't connect Ionic to any database (MySQL, Postgres, MSSQL, ...) directly. The keyword here is directly.
No, there's no workaround, no magic involved, it's just not the way this is supposed to work. Ionic works on top of Angular and Angular is a frontend framework.

Session Types are a way to tell the compiler about the protocol you want to use to communicate between threads - not protocol as in HTTP or FTP, but the pattern of information flow between threads. This is useful since the compiler will now stop you from accidentally breaking your protocol and causi...
Let's say your launch activity is called MainActivity, in your app com.example.myapp.
In the manifest:

The dimension attribute on an object specifies that that object is an array. There are, in Fortran 2008, five array natures:1
explicit shape
assumed shape
assumed size
deferred shape
implied shape
Take the three rank-1 arrays2
integer a, b, c
dimension(5) a ! Explicit shape (default ...
A Range cannot be created or populated the same way a string would:
Sub RangeTest()
Dim s As String
Dim r As Range 'Specific Type of Object, with members like Address, WrapText, AutoFill, etc.
' This is how we fill a String:
s = "Hello World!"
' But we can...

When expecting someone to reproduce an R code that has random elements in it, the set.seed() function becomes very handy.
For example, these two lines will always produce different output (because that is the whole point of random number generators):
> sample(1:10,5)
[1] 6 9 2 7 10

From the documentation :
In C#, arguments can be passed to parameters either by value or by
reference. Passing by reference enables function members, methods,
properties, indexers, operators, and constructors to change the value
of the parameters and have that change persist in the calling

Using the document-ready event can have small performance drawbacks, with delayed execution of up to ~300ms. Sometimes the same behavior can be achieved by execution of code just before the closing </body> tag:

http://example.com/image.png?version=1
http://example.com/image.png?version=2
These two URLs will be cached separately, so even if …?versi...
It is common for an AsyncTask to require a reference to the Activity that called it.
If the AsyncTask is an inner class of the Activity, then you can reference it and any member variables/methods directly.
If, however, the AsyncTask is not an inner class of the Activity, you will need to pass an A...
If your team is following a rebase-based workflow, it may be a advantageous to setup git so that each newly created branch will perform a rebase operation, instead of a merge operation, during a git pull.
To setup every new branch to automatically rebase, add the following to your .gitconfig or .gi...
To change the URL of the repository you want your remote to point to, you can use the set-url option, like so:
git remote set-url <remote_name> <remote_repository_url>
