Must Dependency Injection come at the expense of Encapsulation?
...lare which other assemblies they relied on. It would be a crazy situation, reading docs and just hoping that something works after loading it. Declaring dependencies at that level lets automated tooling deal with the large-scale composition of the app. You have to squint to see the analogy, but simi...
What is the meaning of the term arena in relation to memory?
I'm reading a book on memory as a programming concept. In one of the later chapters, the author makes heavy use of the word arena , but never defines it. I've searched for the meaning of the word and how it relates to memory, and found nothing. Here are a few contexts in which the author uses the...
Regular cast vs. static_cast vs. dynamic_cast [duplicate]
...c_cast<MyClass*>(data);
...
}
int main() {
MyClass c;
start_thread(&func, &c) // func(&c) will be called
.join();
}
In this example, you know that you passed a MyClass object, and thus there isn't any need for a runtime check to ensure this.
dynamic_cast
dynamic_c...
Why would you use String.Equals over ==? [duplicate]
...urs with code that returns things of type Object. If var myItem=GetItem() reads an Object from the database, the expressions "Hi".Equals(myItem), myItem.Equals("Hi"), and Object.Equals("Hi", myItem) will all return True if the returned object is a string with two characters "Hi", but myItem == "Hi"...
Haskell: Lists, Arrays, Vectors, Sequences
I'm learning Haskell and read a couple of articles regarding performance differences of Haskell lists and (insert your language)'s arrays.

Do try/catch blocks hurt performance when exceptions are not thrown?
...
Think of tight loops mate. Example the loop where you read and de-serialize objects from a socket data stream in game server and your trying to squeeze as much as you can. So you MessagePack for object serialization instead of binaryformatter, and use ArrayPool<byte> inste...

No newline at end of file
...not. Diff has to output a newline anyway, or the result would be harder to read or process automatically.
Note that it is a good style to always put the newline as a last character if it is allowed by the file format. Furthermore, for example, for C and C++ header files it is required by the langua...
Does Java support default parameter values?
...e code is probably a bit much to digest for most people (code is harder to read than to write, after all). Thanks again!

Is it abusive to use IDisposable and “using” as a means for getting “scoped behavior” for exception
...mutate and restore state is an abuse; the code is misleading to the casual reader.
Second, because I expect "using" to be used out of politeness, not necessity. The reason you use "using" to dispose of a file when you're done with it is not because it is necessary to do so, but because it is polit...
