Is there an equivalent to CTRL+C in IPython Notebook in Firefox to break cells that are running?
...just sends a SIGINT signal to the code that you're currently running (this idea is supported by Fernando's comment here), which is the same thing that hitting CTRL+C would do. Some processes within python handle SIGINTs more abruptly than others.
If you desperately need to stop something that is r...
ExecuteReader requires an open and available Connection. The connection's current state is Connectin
...faster than to create a new object for any action.

LINQ Aggregate algorithm explained

It partly depends on which overload you're talking about, but the basic idea is:
Start with a seed as the "current value"
Iterate over the sequence. For each value in the sequence:
Apply a user-specified function to transform (currentValue, sequenceValue) into (nextValue)

}
But since require itself follow AMD, you have no idea which one would be fetched early. This is where shim comes to rescue.
require.config({
shim:{
moduleA:{
deps:['moduleB']
}
}
})

IOException: read failed, socket might closed - Bluetooth on Android 4.3
...ely "MOCUTE-032_B52-CA7E" and "Blue Easy". That's the issue, but I have no idea why that problem occurs. Maybe the Bluetooth protocol is trying to get some information from another Bluetooth device.
However, the socket.Connect(); works great right now, without any problems. So I just wanted to shar...
What is the difference between integration and unit tests?
... by using mocks, they removed dependencies. In other words, they run in an ideal, completely fictional world. And this is the only way to isolate bugs and seek them. Unit testing means mocking. If you aren't mocking, you aren't unit testing.
