What is a 'Closure'?
...xpression because all the symbols occurring in it are defined in it (their meanings are clear), so you can evaluate it. In other words, it is self-contained.
But if you have a function like this:
function open(x) {
return x*y + 3;
}
it is an open expression because there are symbols in it whic...
Where'd padding go, when setting background Drawable?
...ing - although interestingly if I added a color, or non-9 patch image, it didn't. The solution was to save the padding values before the background gets added, then set them again afterwards.
private EditText value = (EditText) findViewById(R.id.value);
int pL = value.getPaddingLeft();
int pT = v...
Do try/catch blocks hurt performance when exceptions are not thrown?
...ation as in C#, so this does not really show how much overhead a try/catch means behind the scenes! Just that the IL does not add much more, does not mean the same as it is not added something in the compiled assembly code. The IL is just a common representation of all .NET languages. It is NOT mach...
Compare two data.frames to find the rows in data.frame 1 that are not present in data.frame 2
... work for me, but it seems to only work as shown above if one set contains identically matching rows of the other set. Consider this case: a2 <- data.frame(a = c(1:3, 1), b = c(letters[1:3], "c")). Leave a1 the same. Now try the comparison. It's not clear to me even in reading the options what th...
The type or namespace name does not exist in the namespace 'System.Web.Mvc'
...
Took me a little while to figure out what "those files" meant. Go through the assembly references on every project in the solution, anything with "Microsoft ASP.NET\ASP.NET MVC 3\Assemblies" or the like in the path is part of the problem.

Why do we have to specify FromBody and FromUri?
...mitive types (int, bool, double, and so forth), plus TimeSpan, DateTime, Guid, decimal, and string, plus any type with a type converter that can convert from a string.
For complex types, Web API tries to read the value from the message body, using a media-type formatter.
So, if you want to overrid...
Why should I use core.autocrlf=true in Git?
...d be and it's gone. Instad, it is a problem in the team work. What does it mean "eventually one developer sets true"? Why would you allow them that in the first place? when you set them up for accessing git repo, then just like you don't allow polluting certain areas with different langs (so anyone ...
PreparedStatement with list of parameters in a IN clause [duplicate]
...10, 40, 160, 800. The rest is filled with either zero (zero is not used as ID, usually) or any of the given parameters. This reduces the amount of prepared statements stored in DB's cache.

Why dict.get(key) instead of dict[key]?
...
It allows you to provide a default value if the key is missing:
dictionary.get("bogus", default_value)
returns default_value (whatever you choose it to be), whereas
dictionary["bogus"]
would raise a KeyError.
If omitted, default_value is...
Why do I get “unresolved external symbol” errors when using templates? [duplicate]
...
In (3) you have an typing error. You probably meant keyword and not keyboard. I don't see how defining the functions as 'inline' will help. You need to put them in the header or explicitly instantiate the templates using the types you need.
