Executors.newCachedThreadPool() versus Executors.newFixedThreadPool()
...s crash due to long-time CPU waiting. So I think newFixedThreadPool can be more secure in this kind of scenario. Also this post clarifies the most outstanding differences between them.

Functional, Declarative, and Imperative Programming [closed]
...ramming. The distinction from imperative is that due to immutability (i.e. more generally RT), these "steps" cannot depend on mutable state, rather only the relational order of the expressed logic (i.e. the order of nesting of the function calls, a.k.a. sub-expressions).
For example, the HTML para...
When is assembly faster than C?
...embler 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 where assembler can actually be used to g...
Which is more correct: … OR …
...ould think that the <h1><a>..</a></h1> approach is more conventional though.
In the case where you want to put an anchor on the header, a better approach than <a id="my-anchor"><h1>..</h1></a> would be to use either the id or the name attribute like ...
Setting variable to NULL after free
...little bit pointless if it is "obvious" that the pointer isn't accessed anymore after being freed, so this style is more appropriate for member data and global variables. Even for local variables, it may be a good approach if the function continues after the memory is released.
To complete the styl...
How efficient is locking an unlocked mutex? What is the cost of a mutex?
...le locks would increase parallelism. At the cost of maintainability, since more locking means more debugging of the locking.
How efficient is it to lock a mutex? I.e. how much assembler instructions are there likely and how much time do they take (in the case that the mutex is unlocked)?
The p...
Regular expression to check if password is “8 characters including 1 uppercase letter, 1 special cha
... to break your regex down and do it one bit at a time. It might take a bit more to do, but I am pretty sure that maintaining it and debugging it would be easier. This would also allow you to provide more directed error messages to your users (other than just Invalid Password) which should improve us...
Comparison of Android networking libraries: OkHTTP, Retrofit, and Volley [closed]
... @frostymarvelous: I feel that undocumented and unsupported is more than enough justification. It's not like Google lacks a system for more formally handling stuff like this (e.g., Android Support Library). In the two years since this answer, on the plus side, there's some amount of comm...
Using the star sign in grep
...ell it what you repeat. /*abc*/ matches a string containing ab and zero or more c's (because the second * is on the c; the first is meaningless because there's nothing for it to repeat). If you want to match anything, you need to say .* -- the dot means any character (within certain guidelines). If ...
