no, it's definitely not "fixing," they're pretty emphatic on that point

"remediation" to me has always had the flavor of striking a balance between repair and repair costs. so it's definitely not fixed, but it's better than it was, and that's apparently usuall good enough.

nah. PHP arrays do what "arrays" in other languages do but even better, so there's no reason to rename them. if PHP implemented regular "arrays" they should have a different name, like ShittyArray or maybe even SplFixedArray

fwiw lua arrays also do this, but they call them "tables" instead of "arrays", which tbh seems like a better name because it stops the whining

then again, maybe arrays is the better name for exactly the same reason

what exactly is it that you're bitching about here? that they made a faster interpreter? that's exactly what they should be doing.

code should always be written in the clearest, most straightforward manner possible. if you're worried about performance you're not going to do that; instead you're going to add all kinds of little hacks and "optimizations". (and of course most developers rely on nothing but the power of belief when it comes to these optimizations. what are benchmarks?? i learned about this in my CS class, it must be faster!)

i readily admit that PHP's performance needs to be improved. the only place that can happen is the interpreter. and PHPNG, by all accounts, looks like it's going to be a quantum leap in terms of performance. the future of PHP has never been brighter

seems simpler to me to just call them maps

the way php remembers insertion order interests me, though. does any other language do that? I think some browsers do but not others.

Blinkz0rz: May 27, 2001; MY CONTEMPT FOR MY OWN EMPLOYEES IS ONLY MATCHED BY MY LOVE FOR TOM BRADY'S SWEATY MAGA BALLS

Hey Bloody, Shaggar, c# folks, etc.

what's the best way to deal with event handler spaghetti?

i'm doing a wpf project using the voice recognition api and i want to maintain all the delegation logic in the viewmodel and have each component (i.e. audioinput, audiooutput, recognizer) do its own task

the way i want to do it is to have an audioinput class manage the input audio stream then when it captures data, feed it through the recognizer then send the output to my audiooutput class

i'm using naudio to make audio io a little easier, but now when i get input data i have to do something with it in my WaveIn.DataAvailable event which seems like it encapsulates it in the audioinput class and doesn't let me control delegation in my viewmodel

am i thinking about this the wrong way?

Rx (reactive extensions). Converts the events into effectively a stream. Then you can write .Selects etc over the stream to transform the raw input into whatever you want. Each processor can be encapsulated in an extension method.

alternative takeaway: even the slowest frameworks can handle thousands of times more requests than your lovely internal web app will get, so use whatever is quickest to develop for or easiest to maintain

yup. we use rails pretty happily for our API and it serves up ~1.2m requests per minute no problem.

there are other reasons to not use rails though. the biggest issue of the poor performance is that it is rather indicative of the compounded poor engineering going on, which shows up in other ways

I do enjoy the fact that Vala of all languages actually gets NULL handling right (i.e. you have to opt in to nullability for everything and explicitly test for it if something is nullable)

java.util.Optional is a decent retrofit compromise for the best programming language though

when you have an object with state and you only want its state to be changeable in certain ways from the outside, you mark certain poo poo as private. Then the only methods your object exposes are things that are actually ok to do. Mostly it's there to keep programmers from loving up.

java is a horrible language though, it's basically object-oriented before people actually figured out what the useful parts of object-oriented were.

vs

                   .flatMap(Soundcard::getUSB)
                   .map(USB::getVersion)
                   .orElse("UNKNOWN");
Java programmers must be too stupid to realize how terrible their lives are or they would all have committed suicide by now

not to mention that code requires rewriting the existing classes to support using an Optional, so actually it should look more like this:

Java code:

static String stupidity3(Computer computer) {
		return Optional.ofNullable(computer)
			.flatMap(Computer::getOptionalSoundcard)
			.flatMap(Soundcard::getOptionalUSB)
			.map(USB::getVersion)
			.orElse("UNKNOWN");
}

but really Optional is a really stupid class

if you want to avoid nulls, just write your own:

Java code:

class Nullsafe<T> {
	final @Nullable T t;

	Nullsafe(@Nullable T t) {
		this.t = t;
	}
	public static <U> Nullsafe<U> of(@Nullable U u) {
		return new Nullsafe<U>(u);
	}
	public <U> Nullsafe<U> then(@NonNull Function<? super @NonNull T, @Nullable U> mapper) {
		@Nullable T t2 = t;
		return new Nullsafe<U>(t2 == null ? null : mapper.apply(t2));
	}
	public T or(T value) {
		@Nullable T t2 = t;
		return t2 == null ? value : t2;
	}
}
// and call it like this:
	static String stupidity4(Computer computer) {
		return Nullsafe.of(computer)
			.then(Computer::getSoundcard)
			.then(Soundcard::getUSB)
			.then(USB::getVersion)
			.or("UNKNOWN");
	}

or just check for nulls in a less stupid way:

return computer != null && computer.getSoundcard() != null && computer.getSoundcard().getUSB() != null
? computer.getSoundcard().getUSB().getVersion() : "UNKNOWN";

god that article makes me so angry

future proofing against the hypothetical scenario where you replace or remove the private variable

also the setter allows you to validate inputs because your type system doesn't automatically restrict you to sanity

so when you inevitably have bugs caused by poo poo just mutating parts of an object using the getters and setters you can set breakpoints on the getters and setters, oblivious to the larger design problems in Hyderabad Hustler 2015

it's not a big deal in c# as you can always retrofit properties, not sure why everyone does it there either. makes sense in javaland as you'd have to change variable access to a method
