@mjolka Is it JAVA or Java ?

What takes more space in memory? A HashMap of <Integer,Integer> or a HashSet of <Integer>, and why.

(Remember I am in a performance role).

mjolka

@rolfl good question and i don't know the answer. thank you! my guess would be they take equal space, as i believe HashSet<V> is implemented with a HashMap<V,Object>...

rolfl

^^^ that's right.

mjolka

whewwww

rolfl

How about, when building a network service, would you consider using a Selector on the server socket, provide some reasoning....

mjolka

afraid i don't know what a Selector is

Simon André Forsberg

00:11

@rolfl I believe a HashSet<Integer> is implemented as HashMap<Integer, Object>, so I would say that a HashMap<Integer, Integer> takes more space in memory because that does not only have to keep track of the Object reference for the value but also the actual value of that reference.

mjolka

off to google

Simon André Forsberg

Although one could argue that that extra memory is not in the HashMap itself

rolfl

@SimonAndréForsberg HasSet actually puts the key in as the value too, or null, neither of which takes additional space.

but it is important to know that HashSet uses HashMap under the covers.

Simon André Forsberg

@rolfl Oh, I thought it just used a new Object() for the value of the map.

Jamal

I'm having to do some file I/O now. So far I'm using FileInputStream to read a text file, and I have the operations in a try/catch block. Since it throws FileNotFoundException, I catch that. I then display a message, then return.

None of this has been lectured yet, but screw it; I have the Internet.

However, I'm not doing anything with the FileNotFoundException object. I suppose Java doesn't have something equivalent to C++'s what().

Simon André Forsberg

00:16

@rolfl I think I used selectors in PHP when I did socket programming there (horrible experience). I think that a selector informs about which sockets have changed. If the server socket is returned from the selector then I think that means that there is a new client that wants to connect. If there are some client sockets returned from the selector then those clients have either just sent some data to the server, or are disconnected. What kind of service are we talking about here btw?

mjolka

HashSet seems to re-use this object as the value for all entries grepcode.com/file/repository.grepcode.com/java/root/jdk/openjdk/…

rolfl

@SimonAndréForsberg Actually, it uses a static constant to mark the presence of the value: grepcode.com/file/repository.grepcode.com/java/root/jdk/openjdk/…

What @mjolka says.

Simon André Forsberg

@rolfl that's what I thought

rolfl

@mjolka - selector is a way to box people in to categories.

Simon André Forsberg

(I did not mean a new Object for every key, that would be a waste)

rolfl

00:17

A person who has used a selector, and knows its purpose, has 'been around the block'.

People who have not built a production network service would not know what it was for.

It is/was actually a major feature in Java in avout 2008.

Simon André Forsberg

How close was I with my PHP experience?

rolfl

But it is complicated to use, and most people are never made aware of it.

7 mins ago, by rolfl

How about, when building a network service, would you consider using a Selector on the server socket, provide some reasoning....

The PHP selector sound similar.

The bottom line is that a selector allows you to handle multiple sockets in a single thread by time-slicing the thread.

Simon André Forsberg

yeah, PHP couldn't even spell mutli-trheadnig

5

rolfl

The thinking is that a qhick service running in a single thread is able to service a single network device (hardware channel/ethernet card, etc.), and the cost of thread creation and context switching leads to a slower machine. Slicing the thread is faster

But, the selector is needed so that the thread knows which sockets require servicing.

mjolka

@rolfl this is the kind of thing i was looking for, thank you. when you google for essential things to know about java, it's all like "if you override equals, override hashcode"

2

rolfl

00:21

That is also a good question, but you specifically asked what I would be looking for.

Simon André Forsberg

@mjolka That knowledge should not be underestimated though. You'd probably want to know that too :)

rolfl

> if you were interviewing someone for a java job, what's a sort of "if you don't know this, don't bother continuing with the interview"

mjolka

my point exactly, equals/hashcode are things i know from C#. java-specific things are what i'm looking for

rolfl

For the record, the selector question is not a kill-the-interview question....

it is domain specific, and not everyone has built a service.

Simon André Forsberg

@rolfl Does the service have many short-lived connections or are the connections mostly long-lived? If the service has many long-lived connections that make requests often, wouldn't a multi-threaded approach be better?

rolfl

00:23

A person who can answer it (even if just by passing the buck and saying - Never used one, a thread-per-socket is the system I used), is in a different 'box' than someone who has never heard of it. And a person who never heard of it, is likely just because they never worked through the mid 2000's

Which is OK.

Simon André Forsberg

So it's an age-discrimination question :)

rolfl

@SimonAndréForsberg That's a good question, and requires a long answer.

@SimonAndréForsberg Not really, because big systems are always being maintained too.

I like to ask questions that test the limits of peoples experience.

Simon André Forsberg

@rolfl Sorry, I totally forgot about Mr. Maintainer.

rolfl

I have some questions related to JDBC as well.

The difference between a DataSource and a Connection is a good one.

That typically puts a 'box' around a person's DB experiences.... and the sorts of systems they have used/built.

Simon André Forsberg

isn't a DataSource more like a specific table? At least that's how I understood it from my very limited database programming in Delphi

rolfl

00:26

back in 10 minutes

docs.oracle.com/javase/8/docs/api/javax/sql/DataSource.html

DataSource.^^^^

mjolka

so java's chars are utf-16, just like in c#. i would've guessed utf-8

rolfl

Also, the doorbell is actually, apparently, my dinner.

Technically it is not UTF-16 ;-)

That's another good question.

Java's chars are more like unsigned short (2-byte).

Then applied to Strings, you can actually have chars that are not valid UTF-16 code points in your String.

So, UTF-16 is a subset of char.

gone, b4 dinner gets cold.

Simon André Forsberg

@rolfl a Word as that range (0-65535) is called in Delphi. (I used that type a lot back in the days... miss them a bit in Java)

> An alternative to the DriverManager facility, a DataSource object is the preferred means of getting a connection.

I don't think I've seen a JDBC DataSource ever.

rolfl

Which is why it makes for a good question

} catch (FileNotFoundException fileEx) {

    return;
}

mjolka

you're leaving out a bunch of code, right?

Jamal

Yes. I haven't done anything with these files yet. The file should be read at the beginning, then something should be written to it before the program terminates.

mjolka

can you structure it that way? read file, close file, process data, write file, close file

Jamal

Yeah, I can still do that. I was just keeping everything in one try, but I suppose I can make them separate since this one file just needs to be checked once.

nhgrif

There are more reasons why a file couldn't be opened than just not finding the file.

Dan Pantry

My concern when I was looking at that code was that the read Lock is mutable

But I don't know enough about Java concurrency to really comment

Vogel612

@DanPantry disclaimer ahead ;))

why would it be btw?

Dan Pantry

the current lock, I should say, is mutable

private Lock current;

Vogel612

10:26

the class doesn't expose the lock in any way.

Dan Pantry

No, but it changes within the class, therefore it's still mutable

Vogel612

I don't see the problem with that?

Dan Pantry

say I call downgrade() twice

Vogel612

then you end up with a read-lock.

and that's it.

Dan Pantry

hm, maybe

Vogel612

10:28

you unlock current before replacing it with lock.

my spidy senses tingle when mutability + threading come together

and that again is final..

@rolfl hmm.. Okay then. If he would repeat that, though I'd like to see something like a superping invitation to chat for in depth discussion...

rolfl

Yeah, coming from a lurking position to suddenly confronting you with a question on your profile, I can see how that would be scary.

Stick around a bit more, you will find I am normally the nice guy ;-)

Vogel612

@rolfl normally?? always!

rolfl

I have been somewhat distracted for the past few weeks.

my parents have been in town and staying with me..... I put them on a plane home yesterday ... whew.

@rolfl I'm sure you are, and I'm not worried about you being a bit of a hard-ass on the profile thing. I can see that, out of context, it could have been construed badly :-) If I was in your spot I'd probably have done the same thing

rolfl

@Vogel612 50 shades of grey on that sort of thing ... what if I posted JDOM code here for reivew, would that be spamming?

He's got the message that if he wants a review, he needs to include the code.

Vogel612

@rolfl well you wouldn't plaster it with 10 links and introduce this with: "Hello dear SO-friends, let me introduce you to the newest ~~gui~~ xml lib for...."

Dan Pantry

Is there a strike-through in CR questions? Can't seem to find the GUI button

rolfl

The rest of the post could be taken as a very verbose 'disclaimer' that he wrote the code.....

@DanPantry <del></del> tags

Vogel612

10:46

@DanPantry nope, you need to use html <s>

lol there's a del tag?

Dan Pantry

<del> was not added in html5 and I should l2google

didn't realize the editor allowed raw html tags

rolfl

or This is <strike>struck</strike>

Jeroen Vannevel

Yeah, it's why you can't see html tags if they're not in codeblocks

Vogel612

@DanPantry just a limited subset though..

Jeroen Vannevel

I don't think they work in the chat though

rolfl

10:48

in chat, you can strike with 3 dashes each side, like ---strike--- looks like ~~strike~~ that

So, 3 dashes and 3 carets, looks quite nice as an up-arrow ~~^^^~~ that

looks like a nice roof to me

Q: Architecture of WebGL library and its codestyle

Today, I want to introduce you a new WebGL library, which is rather similar to three.js, when you work with it. I have worked on it mostly after job. I was so inspired by three.js easy way of developing for the web-developers, that I decided to try to do my own one. I can't provide a full sourc...

@Vogel612 sorry for being rude with you in 1st question today. Just have created a project, and I was too happy, that's have blinded me.

@rolfl I've come to discuss, thanks for inventation.

@skiwi what sign? project is rather not small, despite it's 0.0.1, I was trying to create very optimized code and well-structured as I can. If you can see bad design , please tell me what's wrong.

RubberDuck

Hi @Gelo. I was just looking at your pastebin.

I think what @skwiwi means is that if your question can not be broken into smaller chunks, your code is doing too much and should be broken into smaller classes.

From looking at your source, I see why you think it would be difficult to break your question up.

Do you think you could post your camera, renderer, etc. as separate questions?

It's an awful lot of code (2k+ lines). You'll get better reviews if you can post manageable chunks. It's easier for reviewers to focus on the task at hand that way.

Q: Solving the Shortest Path problm (little bit of TSP, too)

Some background info: I'm working at a shipping company and the company's web developer has been fired a week ago. My boss knew that I had some knowledge in web development, so until we get a new programmer, I'm developing the navigation web application. What the application has to do: Well it...

Q: Small android app that gives a movie based on the chosen genre

Working on my first "big" project using the mighty Xamarin. Likewise my first venture in XAML so I suppose most focus will be going towards these new areas. Performance- and user-experience related remarks are welcome as well though. Or you know, just any issue you can see. The solution consists...

Hmmm, @Jeroen .... android and C# in a single sentence .... complicated.

@rolfl Magic!

Right, I see that now.

@rolfl did you see the youtube I posted yesterday?

@chillworld No, looking ......

@chillworld I have seen that one before.

I Think real programmers can get at least four non0intersecting perpindicular lines.

chillworld

@rolfl I find it hilarious cause sometimes it so hard the truth

rolfl

I have been in that situation before, it happens. Not normally quite so apparent, but, when you do a post-mortem on a failed project, you discover, crap, they BS'd us, and the requests they had were contradictory and impossible to reconcile. No wonder we failed.

We just promised to deliver on stuff we would never have attempted if we thought about it more before-hand.

@rolfl I can give you infinitely many so long as I have an infinite number of dimensions to work in.
