Chrome's remote debugging (USB debugging) not working for Samsung Galaxy S3 running android 4.3
...es stopped working as Chrome de-activated the now depracated ADB plugin as it's built in dev-tools now.
I downloaded the SDK and followed the instructions at Chrome Developers. How ever I found the instructions served by Alphonso out not to be sufficient and I did it this way on Windows 8:

What's the best practice for primary keys in tables?
When designing tables, I've developed a habit of having one column that is unique and that I make the primary key. This is achieved in three ways depending on requirements:
...
PHP - concatenate or directly insert variables in string
..., you should really choose the one you prefer :-)
Personally, I would go with your second solution in such a case (Variable interpolation), which I find easier to both write and read.
The result will be the same; and even if there are performance implications, those won't matter 1.
As a sidenote...
Disable dragging an image from an HTML page
...tElementById('my-image').ondragstart = function() { return false; };
See it working (or not working, rather)
It seems you are using jQuery.
$('img').on('dragstart', function(event) { event.preventDefault(); });

When is assembly faster than C?
One of the stated reasons for knowing assembler is that, on occasion, it can be employed to write code that will be more performant than writing that code in a higher-level language, C in particular. However, I've also heard it stated many times that although that's not entirely false, the cases wh...
C#: Printing all properties of an object [duplicate]
Is there a method built in to .NET that can write all the properties and such of an object to the console? Could make one using reflection of course, but I'm curious to if this already exists... especially since you can do it in Visual Studio in the Immediate Window. There you can an object name (wh...

What does href expression do?
...
An <a> element is invalid HTML unless it has either an href or name attribute.
If you want it to render correctly as a link (ie underlined, hand pointer, etc), then it will only do so if it has a href attribute.
Code like this is therefore sometimes used as a w...
How to delete a row by reference in data.table?
...y reference yet.
data.table can add and delete columns by reference since it over-allocates the vector of column pointers, as you know. The plan is to do something similar for rows and allow fast insert and delete. A row delete would use memmove in C to budge up the items (in each and every column)...
How to choose an AES encryption mode (CBC ECB CTR OCB CFB)?
...
ECB should not be used if encrypting more than one block of data with the same key.
CBC, OFB and CFB are similar, however OFB/CFB is better because you only need encryption and not decryption, which can save code space.
CTR is used if you want good parallelization (ie. speed), instead of CB...
