How exactly does the python any() function work?
...is would be especially handy if you created lst using something like lst = range(-1,int(1e9)) (or xrange if you are using Python2.x). Even though this expression will generate over a billion entries, any only has to go as far as the third entry when it gets to 1, which evaluates True for x>0, and...
Is “IF” expensive?
... also have to take into the account the cost of the condition. That could range anywhere from a few short cpu instructions to testing the result of a function that calls out to a remote database.
I wouldn't worry about it. Unless you're doing embedded programming you probably shouldn't be concern...
Cause of a process being a deadlock victim
...NORMAL, or HIGH, or alternatively
can be set to any integer value in the range (-10 to 10).
Q2. If I execute the select with a NOLOCK hint, will this remove the problem?
No. For several reasons:
you should first try to eliminate the deadlock properly, by investigating the root cause

Draw radius around a point in Google map
...t creates circle around points and then show markers within and out of the range with different colors. They also calculate dynamic radius but in your case radius is fixed so may be less work.

Why does an NSInteger variable have to be cast to long when used as a format argument?
...t can make sense in your app to use NS(U)Integer to get a larger available range on 64-bit devices.

How to explore web-based Google Play in another country?
... to a certain country you have to use a host that can send requests via IP ranges or providers that Google recognizes as being from that country. Proxies provide exactly that functionality.
Yes, you are right, developers or others in charge of testing Google services will likely not use proxies, th...

...full (profile) URL), and then ignore any characters outside the acceptable ranges. This works most of the time...
... For when it doesn’t I’ve also had to add a lookup table. As mentioned above, some characters don’t map to a low ASCII value when normalised. Rather than drop these I’ve got a...
Is it possible to dynamically compile and execute C# code fragments?

bool to int conversion
...se of such types (often declared using the identifier bit). On e.g. a mid-range PIC, if (bitVar1) bitVar2=1; would be two instructions; optimal coding for if (byteVar1) byteVar2=1; would be at least four (on many compilers, probably five). Such types can thus offer a major performance boost.
