When is it right for a constructor to throw an exception?
...ause it doesn't match reality. In the real world, some failures cannot be predicted, only detected.

Which timestamp type should I choose in a PostgreSQL database?
... the data from a single perspective in a nearly zero-risk way that behaves predictably in all scenarios. If it were practical for timestamps to support textual representations of timezones, my thoughts on the subject would be different. :~]

Memcached vs. Redis? [closed]
... position in environments, where memory usage has to be enforced and/or be predictable. We've tried to use latest stable redis (2.8.19) as a drop-in non-persistent LRU-based memcached replacement in workload of 10-15k op/s, and it leaked memory A LOT; the same workload was crashing Amazon's ElastiCa...
Finding local maxima/minima with Numpy in a 1D numpy array
... deviations changes with changes in the degree of smoothing cam be used to predict effective smoothing values. A few manual data runs (that are truly representative) should be all that's needed.
All the prior solutions posted above compute the first derivative, but they don't treat it as a statist...
Encrypt & Decrypt using PyCrypto AES 256
...it's important that
# the password have high entropy, meaning difficult to predict.
password = "This is a rather weak password."
# For added # security, we add a "salt", which increases the entropy.
#
# In this example, we use the same RNG to produce the salt that we used to
# produce key1.

Core pool size vs maximum pool size in ThreadPoolExecutor
...uge benefit for your application and its execution environment in terms of predictability and stability: an unbounded thread creation will eventually exhaust the runtime resources and your application might experience as a consequence, serious performance problems that may lead even to application i...
Why does my application spend 24% of its life doing a null check?
...ry likely to be unpractical. Not in the least because you typically cannot predict in which order the nodes of the tree will be visited. A red-black tree might help, it isn't clear from the question. So a simple conclusion to draw is that it is already running as fast you can hope for. And if you ne...
Why is it bad practice to call System.gc()?
...threaded application.
System.gc(); System.gc();
The first call will (we predict) do (live * W1 + garbage * W2) work, and get rid of the outstanding garbage.
The second call will do (live* W1 + 0 * W2) work and reclaim nothing. In other words we have done (live * W1) work and achieved absolutely...
Casting a variable using a Type variable
...correct and things like autocomplete won't work. Simply said: if you can't predict the type(s) at compile time, then how would the compiler be able to?
If the classes that you are working with implement a common interface, you can cast the value to that interface. Otherwise consider creating your ow...
