is there a technical (programming) or even mathematical term for something indicating that if it is present - it is - but if not present, - may or may not be - ? for example, if my class implements

IAwesome

it means that it contains an

Awesome

object val that can be retrieved but that if it doesn't implement

IAwesome

, it means nothing - the class may or may not contain an

Awesome

object

was intellij used for android development (officially) before Kotlin was sanctioned? if so, was it more pleasant than using eclipse for android?

I don't really understand the anti-Eclipse thing because apart from that 2012 android, the last time I used Eclipse was around 2005 for a couple of years - and to tell you the truth, I thought it was pretty awesome back then

so my theory is somehow it got worse over the years?

which I hear was so-so, but I don’t have any experience with it myself

how is the Kotlin plugin for Eclipse, do they keep it up to date?

I haven't used it myself, but I hear mostly bad things about it (unstable, close to unusable). Would be nice to give this plugin a bit more love, it would make it so much easier to adapt Kotlin in a more enterprise environment. I'm more than happy to promote Kotlin, but I'm not a big fan of pushing people away from their favorite IDE, whatever it may be.

I managed to mistakenly hit "Do not show this dialog in the future" on the dialog that appears when I hit the "Git: Update Project" button in IDEA (the blue arrow). Does anyone know how I can undo that? 😄

Same for the taskbar shortcut.

does anyone have any good recommendations on API design / versioning books or reading materials?

Does anyone know how to reload dependencies of a project in AppCode without restarting AppCode? AppCode does not discover changes automatically after running

carthage update

Regex performance Given a string like

field1="x" field2="y" field3="z"

, how can a single regex that matches the 3 field be almost 2x slower than a

indexOf( paramName ) - substring( index ) - split( '"' ) [1]

? Do you use regex for this purpose? I'm just exploring them for the first time.

self-documenting enum values 😂

enum class Case {

		lowercase,
		lowerCamelCase,
		lower_snake_case,
		UPPERCASE,
		UpperCamelCase,
		UPPER_SNAKE_CASE
	}

4-tab indents with tab size set to one character.

@dewildte When the line gets too long, it takes effort for the eyes to move back to the beginning of the margin and down one line. There is a point of diminishing return there, the sweet spot being probably 100-120 characters. Obviously, there are also implications in terms of being able to have two windows side by side, which is super useful in general too.

Do you guys really read every single line from start to end? Especially when skim reading source code? Especially if you know that the rest of the line is unimportant by reading the first bits?

Plus you can and should format lines for readability even when you have a large character limit. I just like to be able to choose.

Hi. I have a request for any non-english (your mother tongue is not english) speaker in this channel. My friend is gathering data for linguistic research, more precisely the verb "HIDE". The goal of the research is to find abnormalities across the language spectrum. Link to the poll: https://docs.google.com/forms/d/e/1FAIpQLSfNrJ00HibjJHT21rLYHj5F4cnN7WwiCJV-jgOrZyC8pO9u5A/viewform This will take 2-5 minutes of your time. Thanks in advance 🙂

Does it mean that I can read

Any?

from the array but write only

X?

and subtypes into it? That

..

confuses me because it looks like a range 🤔 Oh and the

out

thingy can be

null

. The

in

one not.

Hi, by mistake I created a channel here. Can somebody delete #deleteme ?

Hey guys, I have a really random question that’s kinda bugging me, is it really necessary to wrap a

SharedPreference

operation with a

Rx

call? kinda something like

fun save(key: String, value: String) {
        sharedPreferences.edit().putString(key, value).apply()
    }

    fun saveSingle(key: String, value: String): Single<String> = Single.create {
        try {
            save(key, value)
            it.onSuccess(value)
        } catch (e: Exception) {
            it.onError(Failure.Error(e.localizedMessage))
        }
    }

Hi. Does anybody know a software for creating presentations with code highlighting and transitions between code snippets? (Example: )

Can anyone please suggest me a JUnit test generator?
