< outpost[college]>
I need help on java with something really stupid that I've brainfarted.
17:02
< outpost[college]>
I have an object called item, containing int predecessors, and an arraylist of items called Successors.
17:02
< outpost[college]>
 public static class item{ public int pred; //number of predecessors ArrayList<item> succ = new ArrayList(); }
17:02
< outpost[college]>
Specifically.
17:02
< outpost[college]>
And now I need to create an item object called A, containing no predecessors, and an empty arraylist of items.
17:03
< outpost[college]>
But for some odd reason I can't recall HOW.
17:04
<@ToxicFrog>
Just pass 0 as pred?
17:05
<@ToxicFrog>
Or do you mean you don't recall the invocation syntax for new?
17:05
<@ToxicFrog>
(also, by convention Java types are capitalized; Item, not item.)
17:12 * ToxicFrog pokes outpost[college]
17:15
< celticminstrel>
Bah, who cares about convention. :P
17:17
<@ToxicFrog>
Anyone who has to understand your code, including but not limited to your prof, TA, classmakes, co-workers, and yourself next semester when you need to refer back to this.
17:17
< Namegduf>
This presumes you like your prof, TA, classmates, coworkers, or yourself.
17:17
< Namegduf>
But if you do, yes.
17:18
< celticminstrel>
Hehe.
17:18
< celticminstrel>
If it's only yourself, though, you can invent your own convention.
17:18
< outpost[college]>
back, sorry, had a student to help.
17:18
< outpost[college]>
TF - I got the pred, it's the succ that's throwing errors.
17:18
< Namegduf>
You could also make your own custom changes to the language.
17:19
< Namegduf>
And write comments in a form of shorthand that doubles as encryption.
17:19
<@ToxicFrog>
outpost[college]: what sort of errors? How are you creating it?
17:19
<@ToxicFrog>
Something like: new Item(0, new ArrayList<Item>(0)) should work, I think.
17:20
<@TheWatcher>
Better yet, show us the code.
17:20
< outpost[college]>
That throws a 'cannot find symbol error' "constructor Item(int,java.util.ArrayList<topological2.Main.Item>)"
17:20
< outpost[college]>
Honestly, that *is* all the code.
17:21
<@ToxicFrog>
Sorry, 'item', not 'Item'. Read things carefully :P
17:22
<@ToxicFrog>
...can you put initializers inline to field declarations like that in Java?
17:23
< outpost[college]>
I fixed the Item bit, so it's not that. And I'm not sure, I haven't done Java is some 4-5 years.
17:26
<@ToxicFrog>
Hmm. Looks like you can. Interesting.
17:27
<@ToxicFrog>
Ok, so pastebin all of your code exactly as written + the error you get.
17:27
< outpost[college]>
I know it's something very silly I'm forgetting
17:28
< outpost[college]>
http://pastebin.com/dCTmhcNE
17:29
<@ToxicFrog>
Oh
17:29
<@ToxicFrog>
Ok, the problem is that you don't have a constructor for Item
17:29
< outpost[college]>
...
17:29
<@ToxicFrog>
So obviously trying to use constructor-new won't work.
17:29
< outpost[college]>
Well fuck me! and I'm supposed to be a TA/
17:30
<@ToxicFrog>
Oh god, you're TAing a Java course?
17:30
<@ToxicFrog>
I'm so sorry.
17:30
< outpost[college]>
Thank god no, although I need to tutor in it.
17:30
< outpost[college]>
It's even worse. .net and asp.net scripting.
17:30
<@ToxicFrog>
;.;
17:30
< outpost[college]>
I really wish I could do C++ tutoring, I *know* that.
17:33
<@ToxicFrog>
Even if I enjoyed C++ (I really don't) I'm not sure I could ever do C++ tutoring.
17:33
<@ToxicFrog>
It has even more pitfalls and an even steeper learning curve than C or Java, and trying to teach it to people would gradually drive me insane.

<@Derakon>
A good sign your refactoring is on the right track: the new module you've created to hold the refactored code is 204 lines long when you hit the first code review.
20:50
<@Derakon>
(Another good sign: you're taking a global that's used in 45 different places and turning it into a module-scoped variable that's used in 9)
21:07
<@Derakon>
Down to 26 globals~!
21:13
<@TheWatcher>
Dear lord, that guy should be shot~
21:13
<@Derakon>
It was over 100 when I started.
21:13
<@TheWatcher>
Preferably out of a cannon. Into the sun.
21:14
<@McMartin>
There's a sharp minimum on globals well above 0, given that you're using wx, though
21:14
<@Derakon>
Some of them were global even though they were only used within a single function. As far as I can tell the reason was to make debugging with the in-program console easier -- he just imported the module that was used to store globals and checked the value.
21:14
<@Derakon>
McM: how do you figure?
21:14
<@Derakon>
(Though yes, I don't plan to push the globals all the way down to 0)
21:14
<@McMartin>
I think wxApp is required by the API to be global
21:15
<@Derakon>
Ah.
21:15
<@McMartin>
Most GUI libraries generally have some global whose value is "the global event loop" or "this value represents the application as a whole" or whatnot
21:15
<@Derakon>
Yeah, I wouldn't be surprised.
21:15
<@Derakon>
That doesn't really count though, IMO; it's imposed from the outside, so there's nothing we can do about it and little point worrying about it.
21:16
<@Derakon>
(On the flipside, when I started we also had millions of magic-number IDs for various UI widgets which were looked up by said IDs all over the place; I've now eliminated almost all of those)
21:18
<@Derakon>
I'll admit that a lot of my global-removing is actually just moving variables from being in the "seb" module to being in modules more closely related to the global's function, and then doing a mass search-and-replace throughout the codebase.
21:19
<@Derakon>
There's been relatively little refactoring going on beyond that, so modules are still reaching into each others' bits and tweaking them.
21:19
<@Derakon>
But this should at least help clarify the dependency relationships.
21:36
<@Derakon>
23 globals! I now no longer need 'less' to view the list!
21:40
< celticminstrel>
Yay!
21:41
<@Derakon>
Of those, 9 are from crufty old code that's not currently being used, but I'm keeping around because I may need to model new code on it later.
21:45
< celticminstrel>
Sounds familiar.

Derakon: Sounds a bit high to me, even if a CT scan can give you several years worth of background.
22:56
<@Derakon>
Gnolam: well, consider that people who get scans are likely to get several scans of the same location.
22:57
< gnolam>
Then again, you 'mercans seem to go in for a lot of unnecessary scans. And medical checkups in general. ;)
22:57
< gnolam>
Also: cancer estimates from external radiation are notoriously unreliable.
22:57
< gnolam>
Most of them use the LNT model, FFS.
22:58
<@Derakon>
Yeah, no error bars on that estimate.
22:58

Linear no-threshold model?

Yep.

"Risk is directly proportional to dose at all dose levels."
22:58
<@Derakon>
Yeah, I can see how that could be inaccurate.
22:58
<@McMartin>
I'm in my 30s - the competing "Radiation in the quantities our devices produce is good for you!" model sets off a few red flags even if it turns out to be true.
22:58
< gnolam>
Easy to use, but it's so incredibly disconnected from reality that I consider it /pseudoscience/.
22:59
<@McMartin>
ALARA is still the standard protocol, and if ALARA is zero, the answer is zero. =P
23:01 * Derakon mutters, tries to figure out what the different dimensions in a sinogram actually are.
23:02
<@Derakon>
(Sinograms being slightly modified raw data from X-Ray CT scanners)
23:02
< gnolam>
Except that since we don't live in a zero-radiation environment, it's very far from zero.
23:03
<@McMartin>
Well, yes. zero being 'zero added'
23:06
< gnolam>
And if the LNT model is correct, Sweden should have a 25% higher cancer rate than, say, Spain.
23:06
<@Derakon>
What makes Sweden so radioactive?
23:07
<@McMartin>
My understanding was that LNT wasn't considered viable as a predictive tool, only as a regulatory one
23:07
<@McMartin>
Erring in maximally conservative ways for hazards is not a particularly uncommon way to go about doing this, because AFAIK there is no consensus on where the non-linearity threshold *is*.
23:07
< gnolam>
Lots of uranium, higher latitude.
23:08
<@Derakon>
Ah.
23:08
