... It used to be generally recommended best practice1 to use pass by const ref for all types, except for builtin types (char, int, double, etc.), for iterators and for function objects (lambdas, classes deriving from std::*_function). This was es...

... Short answer: no, you do not have to nil out properties in dealloc under ARC. Long answer: You should never nil out properties in dealloc, even in manual memory management. In MRR, you should release your ivars. Nilling out properties means calling setters, which may invoke code that...

... things that may slow down your use of filter. The first is the function call overhead: as soon as you use a Python function (whether created by def or lambda) it is likely that filter will be slower than the list comprehension. It almost certainly is not enough to matter, and you shouldn't think m...

...trong "shake" when the application starts and "hits" the ground from free-fall. However, the code gets used to the gravitation due to the low-cut filter and would work also on other planets or in free space, once it is initialized. (you never know how long your application will be in use...;-) ...

...xample to achieve these: domain1.com -> to Node.js process running locally http://127.0.0.1:4000 domain2.com -> to Node.js process running locally http://127.0.0.1:5000 These ports (4000 and 5000) should be used to listen the app requests in your app code. /etc/nginx/sites-enabled/domain1...

... From developers blog: System.currentTimeMillis() is the standard "wall" clock (time and date) expressing milliseconds since the epoch. The wall clock can be set by the user or the phone network (see setCurrentTimeMillis(long)), so the time may jump backwards or forwards unpredictably. This c...

...luating these "by hand," I'll suggest some simple substitution rules. Basically, you might find it easier to understand an expression if all the iterables are formatted in the same way. For the purposes of unpacking only, the following substitutions are valid on the right side of the = (i.e. for rv...

... count method: >>> [True,True,False].count(True) 2 This is actually more efficient than sum, as well as being more explicit about the intent, so there's no reason to use sum: In [1]: import random In [2]: x = [random.choice([True, False]) for i in range(100)] In [3]: %timeit x.count(T...
