@EthanBierlein Do you write these down and copy paste them from a list every day?

Long ones yeah

I came up with that one on the fly though a few minutes ago.

@EthanBierlein Did I trigger that? I can vaguely remember I talked with you about forkbombs a couple months back.

12:03 AM

@Mast Nah, that was me being stupid and fooling around with it.

That happened ~2 months after you tricked me into running a forkbomb in the terminal.

Can someone help out here? I'm not sure who is correct.

I'd say you

Wow, I've almost gotten +100 rep on Super User today from that question alone.

There's too much omitted code for a good review.

That seems strongly like an opinion.

I've made up my mind, and cast a close vote

Stack Overflow likes brevity, Code Review does not. Adding all relevant code would increase the quality of future reviews. — Mast 11 secs ago

I'm going to upvote it though, since I think it can be a good question.

Thank you.

Once it's fixed.

RubberDuck

Ugh. I think I need to ask a Programmers question...

12:06 AM

Good chance OP is still around, so just keep an eye out.

@RubberDuck Could've been worse.

You could've felt the need to ask a Stack Overflow question instead.

RubberDuck

Yeah. Could be SO

Great minds think alike.

If you have a new question please post (assuming it has not already been asked). Answer are not a place for Code Review or other questions — Matt 23 secs ago

No high end pro coding shop would let you get away with code so badly formatted and crunched up and hard to read. All the good places have coding standards for a good reason - maintainability and to ease peer code reviews. Hard enough to study code that's readable. Just because C lets you get away with murder formatting-wise doesn't mean it's wise to do it. I submitted an edit to make it easier to read your code. When everything looks like a dense pack of crunched together mess it's harder to find bugs. And consistency in formatting is also important. Don't format one way then another. — nerdist colony 20 secs ago

Q: What name would be intuitive for this output option?

I'm currently writing a command-line application which takes multiple arguments. Among those arguments are input and output filenames, modifiers and an option to choose the output. If the option is omitted the application will use the default. 4 different forms of output are available: Termina...

@Mat'sMug Sorry, reflex.

lol

You were practicing for microwave or something.

@Mast you might want to edit that with example command-line, uh, commands

12:47 AM

@Mat'sMug Like python application.py inputfile outputfile option ?

yeah

lol, I was going to have foobar.exe in my answer

like..

wait, do you have to name the parameters?

Well, you can.

python application.py input:foo.txt output:bar.txt ???:terminal

right?

help me out here

python application.py input.txt output -t

Where the script itself would see what the appropriate extension for output would be, based on the option

hmm

12:50 AM

I could even split the arguments

And make it -t for text and -g for graphical

Terminal would always go anyway.

Or -t for text, -g for graphical and -b for both

whatever floats your boat

python foobar.py myfile.txt outputname -t -g

==

python foobar.py myfile.txt outputname -b

seems you got your answer :)

I was going to suggest calling it "to" or "as", but that doesn't really play well with such switches

@Mat'sMug I wouldn't call that one intuitive, it was just an example

Thanks for your input by the way :)

heck, I made an answer anyway (and stole credit for -t and -g ;-)

1:13 AM

man, looking at that logical operators question totally brings me back to that last job's insanity

that piece of software was for power users to be able to determine the rules for applying various promotions

Reading old questions works just the same as encountering old folders on your computer in that regard.

haha

agreed

I looked through my old CR questions recently

nostalgia

How about looking through class zips and finding detailed steps of projects you don't even remember.

That hurts, because you can remember the fear everything won't work out.

And the stress of meeting deadlines when you have 4 other major projects to get done for other classes as well.

yikes

1:21 AM

I usually hide those pretty well.

I sometimes need them for other classes.

They're only in my archive, which I only open in case I lost something I'm sure is in there but no longer on any of my computers. It's a mess.

@Hosch250 I no longer have classes, but that theory applies to code snippets I have around.

You never know when you need to borrow something from an old project.

@Mast Yep. I stick those in a repo on GH.

Some of the code I wrote can not be published, so I never made it a habit to put everything on GH.

@Mast savored it? I got 141 :)

1:25 AM

@Mat'sMug Wasn't going to mention it, but I noticed

Ah well, try passing me on Electrical and we'll talk

Hmm. I need a new project idea.

@EthanBierlein How's Cactus?

@EthanBierlein Join RD.

@Mast so not happening! :D

@Mast Slowing down.

There's not much else I can implement at this point.

I just need to fix a few bugs, and then that's about it.

1:26 AM

@Mat'sMug Quite doable, I'm only at 325 there.

@EthanBierlein No open feature-requests?

@Hosch250 I wish. I know absolutely nothing about WPF, or the likes.

@EthanBierlein code is never "final"

@EthanBierlein Absolutely no need to.

@Mast github.com/ShearOfDoom/CactusReborn/issues/1

@EthanBierlein do you know how to calculate cyclomatic complexity?

1:27 AM

uh

let me look that up real quick

That's Big-O complexity

To answer that, no

github.com/rubberduck-vba/Rubberduck/issues/403

How's your Unity terrain generator going?

> Lines of code; easy. just count non-empty trimmed lines; separate comment lines from actual lines with executable instructions.
Cyclomatic complexity; that's probably a job for a parse tree listener. not exactly a walk in the park, I'm not sure how I'd calculate this metric, but it's certainly feasible.
Maintainability index; even harder, requires the above two metrics, and some "Halstead Volume" figure.
Nesting; report how deeply nested the code is.

1:29 AM

@Mast I actually got it to produce nice results, but I didn't plan on using it for anything. More of a learning experience.

I got it to the point where the terrain didn't just produce something shaped like a human's rear end.

Anyone want to help KO this? programmers.stackexchange.com/questions/298676/…

I can see if I still have a screenshot around.

@EthanBierlein Drive a standard car over it. If that works, use machine learning to generate a car.

I could actually do that.

Unity 5 comes with standard wheel simulations

@Hosch250 Can't vote there, but flagged for blatantly off-topic

1:32 AM

Give me a sec

It has to upgrade the project version.

@EthanBierlein then you're this close to have a Race Track implementation ;-)

Oh, that would be awesome. A 3D Race Track.

@Mat'sMug Whew, that would be one race track!

BTW, I need to study more parts of Roslyn. I just know I'm using the wrong bits for some of my code fixes, and probably some of my analyzers too.

1:34 AM

Well how about that, Unity 5 automatically opens up Visual Studio instead of MonoDevelop.

@EthanBierlein Smoothen it a little, draw some lines and you got yourself a track

That just made my day.

My racetrack isn't much more than just some lines either. There's no AI racing it yet since I couldn't figure out the collision detection.

I'd be happy to have a 3d box moving around

@Mast I think you usually make an array of valid values to check against?

1:36 AM

@Mat'sMug Give me a week or two and you can have that. ;-)

@Mat'sMug That's the easy part in Unity3D, just follow the tutorial

You start with a globe rolling around picking up cubes IIRC

hmm

@Hosch250 Probably. I didn't really go for the usual way but started painting instead.

Playing around with some stranger algorithms:

That still has issues, though, because your car could drive in a straight line through a corner and land on a valid square.

1:39 AM

@EthanBierlein Ah, you're practicing with building loopings?

I'm.. not sure

This is the code that calculates the y position of a tile:

@Hosch250 Make your walls 2 width and you solved that.

float cubeHeight = Mathf.PerlinNoise(
	(cube.transform.position.x / (this.noiseScale + noiseScaleAddition))
    * (cube.transform.position.z / (this.noiseScale + noiseScaleAddition)),
	(cube.transform.position.z / (this.noiseScale + noiseScaleAddition))
    * (cube.transform.position.x / (this.noiseScale + noiseScaleAddition))
);

@Mast Nuh-uh.

Damn indentation

1:41 AM

@EthanBierlein Draw me Caradhras.

This Caradhras?

Caradhras

In the fictional universe of J. R. R. Tolkien's Middle-earth, Caradhras, also called the Redhorn (the literal English translation of the Sindarin name), and known in the Dwarves' language as Barazinbar, is one of the mightiest peaks in the Misty Mountains. It stands above the Redhorn Gate, the only known surface route through the Misty Mountains between Rivendell and the Gap of Rohan. Along with Celebdil and Fanuidhol, Caradhras is one of the three Mountains of Moria, beneath which the great Dwarf palace of Khazad-dûm was built. Below the snowline, Caradhras is described as having dull red slopes...

@EthanBierlein draw me a sheep

@EthanBierlein Yeah.

@Mast I guess for your track it would work, but not all the ones I've seen.

Only place where you could crash through that, is in the first inner bend because that's not two wide. The rest is too thick to crash through, right?

1:44 AM

You can pick up speed each move, you know.

You should probably check all entire grids between your old and new location.

That wasn't my racetrack by the way, I just drew that.

That's mine.

Cool

Hmm

Let's do this

I'm gonna make a racing-esque game in Unity

There's a demo with a car in a sandbox environment. You could use that for inspiration.

Now here's the big question

2D or 3D?

How much time do you have?

1:51 AM

as much time as I want

There's just school and sleep though

Do the 3D one with a minimap in the corner of your screen with a 2D projection of your current location and that of your rivals.

Best of both worlds.

Hmm

Intriguing idea

Just for kicks, instead of calling it "Racetrack", I'm gonna call it "TaceRack"

At least it's unique. That name isn't used anywhere.

Only derivatives.

I should be sleeping, but I'm busy with SciPy instead...

My new job should've started tomorrow, but it's delayed by a month

Grr. It really annoys me how Unity3d always sets a new gameobject at a random position rather than Vector3.zero

@EthanBierlein Just declare it there explicitly and you're done, right?

2:00 AM

Yeah, but it's just a little annoying when I'm creating gameobjects directly in the hierarchy and I have to just tweak the values every time.

Why is my car bouncing thousands of meters into the air?

oh for the love of god

the solution was to simply change my car's mass from 1KG to ~2000KG

lol

so now you know what happens when you drive a 1KG car

2:15 AM

lol

I'm just laughing so much right now because of this

Even a 1KG car should bounce thousands of meters into the air. What did you do, put a helium balloon under it?

@Mat'sMug Oh PPCG, where nothing should be taken too seriously

Depends how much torque you put on that 1 KG :)

Yea, if you put the torque of a 2000kg engine on a 1kg block, it would probably launch.

It's like strapping a rocket to it.

Talking about strapping rockets to cars...

For comparison, a 10KG rigidbody in Unity will only get launched ~30 meters into the air by WheelColliders.

I'm building a car sim in Unity3D. I'm trying to set the properties of the car to be as realistic as possible. I can't seem to get a straight answer on Google so I thought of asking here. What is the typical maximum steering angle of a normal passenger car ?

huh

How about that

I set mine to 60

@EthanBierlein You should try that for real, 60.

Only works when you're driving slow.

2:56 AM

60 degrees @ 60mph == barrel rolls

I might have to abandon using WheelColliders, They're just too buggy.

I'm certainly not going to try and roll-my-own though. That's just too much work.

Can't you make the wheels rigid for now and see what needs to be done later?

Well, yeah, I can freeze x and z rotations on the car, but it produces a non-natural feeling.

Q: moving the logic for determining if a string is a palindrome

Anyone still around?

nope

Ah ok

3:26 AM

lol

Still thinking of my DBO builder class ... right now I made a create() method that actually feeds the parameters into the builder... and all other methods need for the builder to be created before they can do anything with the object

So would it make more sense to move the logic to create the builder into say the constructor?

I'd try to avoid doing all the work in a constructor

The constructor should do one thing and one thing only.

Initializing the parameters for the object instance? (and making the object obviously)

Does your method insert data into your class or does it initialize the class?

3:31 AM

The create() method only initializes the DBO builder by passing it the input parameters

Well, maybe that's not really initializing then, since it does put data in it

Guess I got my answer :)

A constructor should only initialize. Everything else should get a member function instead.

quack!

AFAIK

sounds right

Thanks duckies :)
