The example I gave is an implementation of Function<I,O>, but this again is an interface that could be either a lambda or just an implementation of that interface
Further:
> State/Strategy Pattern - I group these together because they are structurally equivalent, just different in intent. Strategy usage become much more common because it is easier to implement. You don't need a parent strategy and strategy subclasses, you just need functions. So it is simple to just pass a function as a parameter, which in effect is using the strategy pattern.
Many claims that the biggest part of the GoF design patterns are just workarounds for the absence of first class functions. Now that Java is about to get lambda expressions, which of those patterns will be influenced by them? Which ones can be dramatically simplified or generalized? And which one...

There was some text I read a while ago, detailing various situations, going like "If you've experienced x, seen y happen, watched as z came to pass, (insert 20 more items here), well, then you'll know what it means to be a privateer, my son."
That stream code of yours is only missing the last bit.
It doesn't provide breaks, instead uttering a full sentence, subclauses and all, taking only a minor breath with each comma, ever so slightly turning a distinct tint of blue from asphyxiation, before finally ending the sentence with a soft, but resounding, semicolon.
@Pimgd I find it clutters in the code length if you do it like that, though I am using very simple constructs here (once you are familiar with Streams), for anything non-simple I use the more lengty-way
@Pimgd .map(possibleWord -> possibleWord.getSymbolChoices().stream().map(SymbolChoice::getSymbol).collect(Collectors.joining())) is quite simple, it's just a shame it needs to be written in such ugly way
It's a shame in my opinion that you need to go through the Streams-api here, as mapping a List<X> to a List<Y> using a mapper Function<X, Y> and joining a List<X> to a string using a mapper Function<X, String> seem to be very common operations
Given a chess coordinate as a string (e.g. "a1") I'd like to transform it into a 2-D array (so, for "a1" I'd like to get [1,1]).
Here's what I came up with:
def safe_pawns(pawns)
pawns.inject([]){|res, pwn| res << [pwn.split('')[0].index(/[a-h]/) + 1, pwn.split('')[1].to_i]}
end

Please can someone explain to me how I should go about deciding whether to use expect or should syntax for my rspec examples.
From my understanding we should no longer be using the should syntax.
The replacement is to use expect().to or is_expected.to
Is this correct?

@Pimgd That's not of an issue where I work, code is first of all all located somewhere in the magical cloud, and there's backups around somewhere as well
Unless you have zero competitors, or your product is so terrible that any competitors you do have think there's literally nothing to gain from your product.
@Vogel612 But you need all technology and expertise yourself... You cannot have another person/company monitor them for you, because then they need to be accessible via the Internet
Brackets are tall punctuation marks used in matched pairs within text,
to set apart or interject other text. Brackets refer to different
types of brackets in different parts of the world and in different
contexts. Write a program which reads a String, which consists of
alphabets [a-z, ...
I need to get the average of multiple averages calculated basing on data on a sql database.
To do that, I'm using this code:
$a = mysqli_fetch_assoc(mysqli_query($connessione,"SELECT AVG(voto) AS mediaa FROM values WHERE type ='a'"));
$b = mysqli_fetch_assoc(mysqli_query($connessione,"SELECT AV...
@Vogel612 Then back to the starting point... What is the difference we are talking about internal vs cloud? Is it the fact that cloud has access to the code itself as well?
Plus, there's the fact that the code itself is on a local server so you could access it if the internet went down. In a setup like this, I'd probably keep a copy at each location.
Is it even realistic to assume the Internet would be down for a prolonged period of time? And attach unique risks to that
You probably work with other developers and companies, and they might rely on the Internet to work, and if you do not get stuff from them, you are screwed either way
If 1) Your company's net would go down, it would be fixed in a matter of days worst case, 2) If the Internet would go down, your IT-company would be screwed either way
I do not see the risk, assuming you always have some kind of local stuff around with which you can fiddle around
@Vogel612 I remember years ago when Computers were running Windows 98, if I used a Linux computer I could issue a flood-ping, and violà the Windows user couldn't do anything at all.
There is the '\x' way of entering numbers hexadecimally: (Source http://www.regular-expressions.info/reference.html )
yourString.matches("[\\x00-\\x7F]+");
In Java this might be:
yourString.matches("[\\u0000-\\u007F]+");
Am I really the third person to post a live Code Snippet for review? meta.codereview.stackexchange.com/questions/2467/… At least my tiny piece of code has the bonus side effect of overflowing the stack (with large enough input.)
@wnnmaw Yes, it can be on-topic. Assuming that you provide enough context, and that you post your real code. (We don't like to see stripped-down examples)
@SimonAndréForsberg, well that's what I'm struggling with, I'm trying to decide if implementing the second method is worth it in my 8.5k line code, so how stripped-down can I go before I irk someone?
As stated in the Help Center, one of the criteria for a question to be on topic is:
Is it actual code from a project rather than pseudo-code or example code?
What is the rationale for that rule?
