Oregon Trail

The Oregon Trail is a historic east-west large wheeled wagon route and emigrant trail that connected the Missouri River to valleys in Oregon. The eastern part of the Oregon Trail spanned part of the future state of Kansas and nearly all of what are now the states of Nebraska and Wyoming. The western half of the trail spanned most of the future states of Idaho and Oregon. The Oregon Trail was laid by fur trappers and traders from about 1811 to 1840 and was only passable on foot or by horseback. By 1836, when the first migrant wagon train was organized in Independence, Missouri, a wago...

excellent. OK, I have to make a plan.... I have a RAID1 array. One of the drives is borked.

The other drive appears fine.

Do I trust the other drive?

It was bought at the same time as the first.

It is identical to two other drives I have.

If I add it to the same RAID array as the other two, I get an additional X Terrabytes of storage.

Alternatively, I can make it a new off-site backup disk.

I think I will do that....

Currently, though, for your kicks:

Almost ready to share small piece of code

@SimonAndréForsberg This is my console in GUI implementation...

    public void start(final Stage primaryStage) {
        primaryStage.setTitle("Console in GUI");

        BorderPane borderPane = new BorderPane();

        TextArea textArea = new TextArea();

            if (keyEvent.getCode() == KeyCode.ENTER) {
                textArea.appendText(textField.getText() + "\n");

That's all you need to mimick a console.

skiwi

@Malachi Yes

Malachi

6:04 PM

if I upgrade to micro so that I can have a private repository can I create more than one that is private or will I have to pay more for each one?

I think it's up to 5?

Let me check though

Malachi

I suppose this is the only one that I am working on at the moment, maybe I will start with the RPSLS game

skiwi

'https://github.com/settings/billing

It's five

Only thing left to figure out in with JavaFX is how to implement when a message has been typed properly

Because honestly the design of System.in and System.out is horrible

Malachi

thanks skiwi

I am going to figure out how to use it and stuff before I start paying for it...lol

skiwi

Ever worked with git or github before?

Also I think Travis CI (Continious Integration) is quite awesome

Unfortunately if you're using a private repo, then you'll aalso need to pay for Travis, it's free for public

You can check an example at: travis-ci.org/skiwi2/TCG/builds

Basically every commit to your repo will be automatically build on some server in the cloud, and you can do whatever you want during/after building.

Malachi

6:15 PM

I have an account but I have never worked with either

what is Travis CI?

skiwi

What I just explained there above :)

@SimonAndréForsberg For extra fun in JavaFX 8, add this to all your text fields:

textField.addEventFilter(KeyEvent.KEY_PRESSED, keyEvent -> textField.setRotate(textField.getRotate() + 1d));

Simon André Forsberg

@skiwi lol, rotate the textfield on key press? No thanks :)

skiwi

It's so fun that it just works.

With Swing that would be a hell of a headache to get working :)

Simon André Forsberg

@skiwi How do you deploy JavaFX apps though? Do they become webapps or are they pure JAR or what?

skiwi

Pure JARs for sure

webapps I have no clue, given the history, that might also be possible

The history of Java I mean, not of JavaFX per se

Once I manage to get this working decently I might push it to github later tonight

I've written these two command-line tools to be used to facilitate forestry surveys.

Not only that, but he has to account for the fact that you can't turn a cylinder (trees) into rectangular prisms (boards) without a bit of loss. So wha…

@SimonAndréForsberg Good, I have a question

Simon André Forsberg

@skiwi Shoot

skiwi

As you know, my game loop consists of continiously the self player and opponent player playing their turns

Simon André Forsberg

Yes

skiwi

In the previous situation I was using System.in, which is a sort of blocking UI to process events

Now I have moved to the console thing and hence it's non-blocking anymore

I'm struggling how to get still hand over control to the players

A turn for example only ends when a player indicates so (by a typed command)

Simon André Forsberg

8:00 PM

I think that it's not correct to have a "game loop" at all. Your Game.play method would make sense if there's two AIs fighting, but it's not.

Malachi

I am so confused

skiwi

How would you make it work without a loop then alternatively?

@Malachi I am confused about what you're being confused

Malachi

I am trying to get my Xamarin to let me commit to my Github

and I don't think I know what I am doing enough to do that.

Simon André Forsberg

@skiwi Let me ask you a question first: Why do you have a game loop? What is it supposed to do?

skiwi

8:15 PM

@SimonAndréForsberg "Play" the game, primarely help would be if one player is human and the other AI (or networked)

The AI and networked would both work in a blocking way I suppose, at least linear

skiwi

@Malachi Maybe this helps?

forums.xamarin.com/discussion/10097/adding-project-to-github

Simon André Forsberg

8:30 PM

@skiwi I think you should remove the loop. Or at least, don't use the game loop when you're using your UI. The UI creates the game object and starts the game, and then you can call performAction methods and endTurn method(s)

Malachi

@skiwi not really, my XS doesn't have a publish option, I saw it before but I don't remember where that was, all the menus that say Version Control don't have Publish in them

I have a playfaire cipher application that has some parts that I didn't finish yet.... hope I can remember what I was doing

Is there also a way while still leaving the loop intact?

@SimonAndréForsberg I'll go with the blocking approach for now, this code will surely be up for review ;)

Interesting...

Exception in thread "Thread-4" java.lang.IllegalStateException: Not on FX application thread; currentThread = Thread-4

It complains on a method call

nhgrif

I'm sure you know you can't manipulate the UI from background threads, right?

skiwi

I don't think Swing ever raised an issue about that.

But it is logical actually

Then question is: How do I do it?

nhgrif

9:16 PM

Manipulate UI from a background thread?

Have the background thread tell the main thread to do it.

skiwi

that would only be possible if I could obtain the main thread, will need to look into that

As here the main thread is kind of implicit

nhgrif

The main thread is "kind of implicit"? The main thread is the thread from which the application is launched, the thread which is in charge of the UI, and the thread from which any other thread originates (or originates from a thread which originated from here, etc)

skiwi

Appereantly I need to wrap the calls in Platform.runLater(Runnable runnable)

That's the preferred way to make things run on the javafx thread

nhgrif

I actually don't know if it's a hard rule in Java that you can't manipulate the UI from background threads. In some languages, you simply can not do this at all. But in all languages, it is highly recommended against doing this.

The thing is, the UI thread is the one the user interacts with. You don't want to get in a race condition with a user click, etc.

skiwi

As from experience with Swing (the second GUI stack), nobody pretty much cared

But I do understand the issues

nhgrif

9:24 PM

And it's the same reason why operations that take any amount of measurable time should be put in the background. If your UI thread is spending 2 seconds sorting an array, or fetching a file from the web, that's 2 seconds your UI is "locked up" and can't respond to user interaction.

skiwi

The latter you explain (extensive tasks in background thread) is the easy part to understand

Why it isn't allowed the other way around is a bit more implicit

You would say this is easy... But without knowing JavaFX much, I have no clue how to get my Scene increase it's width as the width of my content increases (fit-to-content), will be a challenge to find out

nhgrif

And not only do you want race conditions between a background thread and the user, you don't want race conditions between two background threads trying to manipulate the same pixels, etc.

I'm not familiar enough with Java to know much about communicating between threads in there, and I know nothing about JavaFX. Just know the basic principles of what you should and should not be doing on what threads in general.

These things are relatively painless in Objective-C, fortunately. ;)

skiwi

Enough code for today :)

rolfl

@Malachi Which code, where ...?

Malachi

@rolfl that one Java Question. I didn't leave the answer. I caught it before I posted

for (int i = 0; i < values.length; i++) {
    if (i > 0) {
        sb.append(", ");
    }
    sb.append(values[i]);
}

I was going to suggest this

StringBuilder sb = new StringBuilder();
sb.append(values[0]);
for (int i = 1; i < values.length; i++) {
    sb.append(", " + values[i]);
}

I have a question that I am about to post about a shift cipher

rolfl

9:41 PM

In this case, your code is likely fine.

There are so many things wrong with my code, and so many things wrong with yours too.

In reality, neither of the versions (yuors, nor mine), is robust at all.

The reason I don't use the system you suggested often, is because I can't always guarantee the existance of element 0.

In this case, you can.

Right, what a day.

Reinstalled this computer, seems ot be working.

Malachi

@rolfl Java is Zero Indexed always isn't it?

rolfl

Yes, but an empty array has no member 0

Malachi

oh

rolfl

In this case, though, a split will never produce an empty array. At worst, it will produce a 1-member array of an empty string.

The Double.parseDouble() will throw exception on the empty string.

The values[0] will not matter.

Malachi

I need to find me some Java Books and read everything I can get my hands on. I found out that I can make $30k more a year if I work for the same company that my dad works for, he does AS400 stuff but programming in Java would get me in the door pretty good there.

Jerry Coffin

@Malachi I didn't analyze your code carefully enough to check what it does with upper- vs. lower-case letters, but for the typical case where you only want to transform upper-case letters, you can write the entire program (including file I/O) as a single statement:

    int main(){
        std::transform(std::istream_iterator<char>(std::cin),
	               std::istream_iterator<char>(),
                   std::ostream_iterator<char>(std::cout),
                  [](char ch) { return std::isupper(ch) ? ((ch - 'A') + 3) % 26 + 'A' : ch;});
    }

rolfl

^^^ bug in that.

Jerry Coffin

@rolfl What bug would that be?

rolfl

  ((ch - 'A') + 3) % 26 + 'A'

... the decode takes a negative shift.

So, you should, in theory, have:

Jerry Coffin

@rolfl Yes, this is only encoding.

rolfl

11:46 PM

true, the shift is a constant.

Mat's Mug

hi!

rolfl

Hi! (to @200 too)

Jerry Coffin

you could do it as something like:

int shift = /* 3 or -3 */;
// ...
[shift](char ch) { return ((ch-'A')+shift)%26+'A'; }

Hi!

rolfl

You could also limit the shift to -26 < shift < 26 and have [shift](char ch) { return ((ch-'A')+(shift + 26))%26+'A'; }

Which will do the decode and encode botrh

Jerry Coffin
