Are there known valid uses of SLOC to measure productivity?

I had an unusual, brief conversation with a very senior architect about dynamic and static languages. He said that company data shows that there is evidence for higher productivity when static languages are used. Note, it's a large company with long…

Are the development benefits of using Docker negated when using Java compared to other languages closer to Unix binaries?

I had a friend who said: Docker is amazing. You can use it to replicate production and all its quirks on your local machine. Then you can deploy that instance straight through all the staging workflows super-quick. Now this would be true if the…

Is using Lambda expressions whenever possible in java good practice?

I have recently mastered the Lambda expression that was introduced in java 8. I find that whenever I am using a functional interface, I tend to always use a Lambda expression instead of creating a class that implements the functional interface. Is…

Why would the 'final' keyword ever be useful?

It seems Java has had the power to declare classes not-derivable for ages, and now C++ has it too. However, in the light of the Open/Close principle in SOLID, why would that be useful? To me, the final keyword sounds just like friend - it is legal,…

How much stack usage is too much?

Lately when I've been writing C or C++, I'll declare all my variables on the stack just because it's an option, unlike with Java. However, I've heard that it's a bad idea to declare large things on the stack. Why exactly is this the case? I…

Why is chaining setters unconventional?

Having chaining implemented on beans is very handy: no need for overloading constructors, mega constructors, factories, and gives you increased readability. I can't think of any downsides, unless you want your object to be immutable, in which case…

Why do we need frameworks for dependency injection?

I've been reading up more on the Inversion of Control principle and Dependency Injection as an implementation of it and am pretty sure I understand it. It seems to be basically saying 'don't declare your class members' instantiations within the…

Why would a program require a specific minimum number of CPU cores?

Is it possible to write code (or complete software, rather than a piece of code) that won't work properly when run on a CPU that has less than N number of cores? Without checking it explicitly and failing on purpose: IF (noOfCores < 4) THEN don't…

Why design a modern language without an exception-handling mechanism?

Many modern languages provide rich exception handling features, but Apple's Swift programming language does not provide an exception handling mechanism. Steeped in exceptions as I am, I'm having trouble wrapping my mind around what this means. Swift…

What are the advantages of Scala's companion objects vs static methods?

Scala has no static-keyword, but instead has similar functionality through companion objects. Behind the scenes the companion objects are compiled to classes that have static methods, so all this is syntactic sugar. What are the advantages of this…

Doesn't "if (0 == value) ..." do more harm than good?

This is one of the things that I hate most when I see it in someone else's code. I know what it means and why some people do it this way ("what if I accidentally put '=' instead?"). For me it's very much like when a child goes down the stairs…
