@Bhathiya ^^

@DanPantry If someone is mentioning Scala, it's either me, or someone talking about me. :-)

@Vogel612 og-god-.-nooooo

But when choosing a language, advantages and disadvantages are entirely context dependent. The biggest advantage of Scala for me is that I can think and work in it better than I can any other language I've ever been exposed to.

Though sometimes I miss the old days when Pascal was all I knew and the language API was so limited that you pretty much had to roll everything yourself.

@DanPantry welcome back

@DanPantry do you indent two spaces or four when you are writing Lua?

@bazola the answer is always tabs. let the reader choose their tab size. :P

@Mat'sMug Not sure what I'm writing (still need some refactoring), probably some monstrosity.

@Konijn beat me to this one -> codereview.stackexchange.com/a/60808/18427

Uh oh. Tabs vs. Spaces

Q: Implementation of a AVL Tree

I attempted to write a AVL Tree in a functional style and I was hoping to get it reviewed. This is my first review, so please forgive me if this is too general of a request. I was looking for the code to be clear and concise, any opportunity for improvement would be greatly appreciated! Thank you...

c# data-structures tree

good song.

@Phrancis will read later

@bazola 2 spaces these days for anything that isn't C#. in the old days i used to use tabs then realized how awful they were

@DanPantry I'm the opposite; I used to always use spaces, until I had to work with coworkers with vastly differing indentation preferences

@Schism i'm not a very accommodating person you see :p

4:59 PM

Would there be people who prefer indentation of 16 tabs?

TFL

well thanks for the advice from both of you

the IDE i am using was just tabbing to 2 spaces, i thought it was doing 2 spaces manually :)

@bazola it really is down to personal preference just pick what is readable for you

i just didn't know if there was some language convention for Lua because a lot of the code I see is 2 spaces. Objective-C with Xcode is always 4

@bazola python is 4 spaces

5:01 PM

@bazola majority I see is two spaces as well, but I think that's because 4 spaces is pretty excessive. I think people only use 4 spaces because that's how many spaces make up a tab

@Bhathiya-JaDogg-Perera great! can't wait to review it!

i hope I have not opened up pandoras box :)

@skiwi ^^

16 space indentation

pretty sure after 3 indents you'd reach the vertical rule

So, I'm just gonna vent this. Programmers should not have to write a business case to get Git installed.

@DanPantry pretty easy to make a GUI using Lua? I'm eventually going to need to make one for a business app to interact with my PL/pgSQL DB and I need it to work on OSX and Windows machine both

(but no other device)

I was going to learn Java but seems a bit overkill to make a simple GUI

5:15 PM

@Phrancis No clue, I only used lua for WoW-related cases.

Lua is not a stand-alone language though and needs to be embedded within SOMETHING

Ah. Maybe I should just stick to Java

you could check out Love2d

and I'm pretty sure there are going to be some kind of gui libaries ported to lua (read: Qt)

there it is

fk sake

my USB harddrive is mapping to G: instead of E:

so all of my references are broken

what do?

@Phrancis ouch

@Malachi rubs-it-in

@RubberDuck I ended up replacing IRepository for IUnitOfWork on all IPresenter implementations. I'd put up the UoW for review, but transactions don't seem to work (I don't commit anything and it gets to db, and rollback doesn't do anything) so I might end up on SO first...

@Mat'sMug lame.

Wait. You're doing transactions?

6:01 PM

damn right

Nice.

Transactions easy to do in ~~WtfSQL~~ MySQL @Mat'sMug?

well the only problem is I don't know why MySQL actually performs an update without committing the UoW

@Phrancis thought so..

connecting through ADODB with a MySQL provider

I used to use a libary called SharpRepository that would always save to the underlying DB layer without using commit

it was infuriating

Private Sub Class_Initialize()
    adoConnection.ConnectionString = CONNECTION_STRING
    adoConnection.Open
    adoConnection.BeginTrans
End Sub

6:03 PM

close this.

This question appears to be off-topic because it is about 3 different programs, each program should have it's own question. — Malachi 14 secs ago

that doen'st make it off-topic, does it?

@DanPantry well I know ADODB transactions work perfectly fine with a SQL Server provider

I think it just makes it a bad question

downvote, perhaps? closing seems a bit extreme

@Mat'sMug I was just thinking of editing out the code that doesn't match the Title.... thoughts?

A: php adodb StartTrans() is not working?

There are two different drivers for MySQL in ADOdb: mysql mysqlt The first one (What you probably used) has no transaction support while the second one does. Try using the mysqlt driver: $conn = ADONewConnection("mysqlt");

@Phrancis I downvoted as well

That's a thought, @Malachi.

I am going to write a meta question about that

real men don't need IDEs

LOL

~~NotePad++ is an IDE~~

> An integrated development environment (IDE) or interactive development environment is a software application that provides comprehensive facilities to computer programmers for software development. An IDE normally consists of a source code editor, build automation tools and a debugger

@DanPantry I've done "real men" programming, and just for the record, that's the stupidest meme in the universe.

6:13 PM

Notepad++ is a text editor that may or may not have syntax highlighting :(

at least, that's all I use it for

@Donald.McLean it was a joke :P I wasn't actually being seirous

serious *

@DanPantry if you press the up key on your keyboard you can edit your chat posts for a limited time

@DanPantry You can never tell. Some people actually believe that.

@Malachi I know, I'm just too used to NOT being able to do that, that it becomes force of habit :(

@DanPantry I hate not being able to do that on my browser games and stuff now...

@Donald.McLean I was starred earlier as saying - sarcastically - "in my day we didn't have your fancy shmancy coffeescript, we wrote REAL codes in javascript" or something to that effect

I don't have a view of "real programmers", if you program that's good enough for me :p

6:16 PM

@DanPantry LOL. The first programming I ever did was Fortran 4 on punch cards. They ran student programs on Wednesday and Saturday.

@DanPantry the fact that you have two Skype icons on your taskbar is bugging me

goddammit what's the naming convention for java files again

@Schism: I have two skype accounts

@DanPantry Yes.

@RubberDuck UnitOfWork is up for review :)

@Mat'sMug Nice.

I'll try to check it out.

I'm still writing up that business case.

Q: A rather creative UnitOfWork

Who recommended Gradle to me?

Simon André Forsberg

@DanPantry Depends: Did you like it?

6:45 PM

Lol. Can you explain why Gradle is trying to use a git url that I haven't actually typed in? prntscr.com/4fejxl

Simon André Forsberg

@Phrancis Even though that uses Swing, which is a bit old by now as JavaFX has entered the scene, I think that should work for you, yes.

I'm open to suggestions, but I'm going for functional over pretty, this will only be used by me & my graphic design partner to manage customers and projects

Simon André Forsberg

@DanPantry No, I can't explain that

obligatory

Simon André Forsberg

@Phrancis Swing should definitely be enough for you then, yes.

6:46 PM

user image

OK thanks @Simon

Simon André Forsberg

@DanPantry I haven't used Gradle much myself, I have a hard time understanding some things about it.

i'll just go back to maven for now, -sigh-

I really hate xml

oh bugger me

the plugin created a folder in my project root that had a git repo that pointed to the wrong one

@RubberDuck hint: there's something fishy about cleanup

Simon André Forsberg

@Mat'sMug Looking for @ckuhn203? Try @RubberDuck

6:48 PM

yeah

lol

Class_Terminate won't get called unless all references are cleared.

Hey @Mat'sMug... I hate to say this, but you might want to rethink mentioning this.

> The code works, but I'm having issues with transactions because of MySQL (not sure if it's the driver or the underlying db engine, but everything just goes through as if there was no transaction involved) - but that's irrelevant to the actual code - I'm sure I can hook this up to a SQL Server backend and it will work just as expected.

That really makes it sound broken.

@SimonAndréForsberg now if I copied the whole Java script into my IDE would it normally just compile to do exactly what this does?

@RubberDuck no clue where you took that quote from ;)

Anyway. I'll try to look later, but who knows, maybe @ptwales will show up first.

java lambda syntax is arg1,arg2,arg3 -> { } right?

or are they only able to be singular expressions?

Simon André Forsberg

6:54 PM

@Phrancis Yes, it should do exactly what that does

@DanPantry (arg1,arg2,arg3) -> { }

@DanPantry Care to clarify what you mean exactly?

Simon André Forsberg

or, if you only want to use one statement then you don't need the { }, just write the code directly

@SimonAndréForsberg and I'm assuming you can supply the () if you want a zero-arg lambda?

Simon André Forsberg

such as (arg1, arg2, arg3) -> arg1.do(arg2, arg3)

OK thank you, I'll tinker around with it this weekend

Simon André Forsberg

6:55 PM

@DanPantry correct

if so that is quite literally Ruby's lambda syntax lol

@RubberDuck LOL

lol-autostar out-of-ammo

Simon André Forsberg

@DanPantry I guess it's quite hard to innovate new lambda syntaxes (Python doesn't count), although I think it's a good think that they re-use the same syntax as other langauges

@SimonAndréForsberg Python's lambda is just an expression that is wearing fancy dress :(

6:57 PM

@Malachi Seriously, why do I have to justify the fact that we need version control software?

Free software, I might add.

@Phrancis click click click

@RubberDuck legacy software in my work uses SVN. It's really painful

Which will actually be a huge pain in the ass because it's opensource.

@RubberDuck SVN is fine and all but not when you put EVERY SINGLE SEPARATE PROJECT into one folder and version it all together

Where I work opensource == evil

6:58 PM

Not to mention we have VS12 with TFS integration, it makes no sense to not use TFS when it's so useful and we already have it there for us

We're using nothing right now @DanPantry.

I am in the middle of trying to figure out with folder holds the Current production code and also which version of Visual Studios it works in....

@Malachi those two memes combined... might collapse the universe

so I can change something that I should be able to change in a db table. but this site is so old they didn't do that back then....

@RubberDuck: My boss suggested .rar/.zipping up project files and time/dating them. I feel this is only slightly worse than what you have. So I feel for you.

6:59 PM

That's more or less what we're doing.

@DanPantry that is pretty much the same same thing, only with less bells and whistles

2

Nobody can work on the same project at the same time, regression all over the place.

I think I need a smoke. bbl

lol

@Malachi except those bells and whistles actually make it practical :P

I'm going to assume jUnit is the main test framework for Java

@DanPantry Would be a great assumption ;)

7:04 PM

maven = magnets

how do they work

maven install maven build I guess

maven test for testing, I hope to god it works out I'm using junit

the one thing that frustrated me about maven was all the Xml but also that it seems to be incredibly bloody dumb

If you're up for a challenge, I would go with Gradle

I was using Gradle

I think it's way better than Maven, but has less mature support in IDEs etc., yet it does work.

stopped using it because it didn't natively support git repositories as dependencies

and the plugin that DID support it was also dumb

Yeah... Gradle is a challenge to use

7:05 PM

prntscr.com/4fes1e

Eclipse.. why?

is that really necessary

I'm happy I got my first handmade web server/service code done... Only thing left i sto implement a SE chat bot and a github post hook

well done :)

Simon André Forsberg

@DanPantry why not?

@SimonAndréForsberg: I'm already aware i have src/main and src/test etc

I don't need to see it twice

Simon André Forsberg

What if you put a file at src/wronglocation ?

7:08 PM

sounds like you put it in the wrong damn location ;)

why on earth does eclipse not have a ui for adding dependency repositories

Simon André Forsberg

sounds like you're complaining a lot today @DanPantry

It does have an UI for that. Right click project -> Maven -> Add dependency

@SimonAndréForsberg It can add dependencies, not repositories

@SimonAndréForsberg Also, I'm British. Complaining is our country's export

Simon André Forsberg

@DanPantry Are you sure you're not mixing it up with Sweden?

@SimonAndréForsberg I'm not named after a desk, so yes, 100% sure

Simon André Forsberg

Named after a desk?

Simon André Forsberg

Considering how nearly all things you want to add as a dependency are at maven central, there's often no need to add a repository

There is for Bukkit :(

Simon André Forsberg

Well, that's Bukkit :)

I haz a bukkit

Simon André Forsberg

I waz doing Bukkit pluginz

Although only one is released

And it's code is quite crappy

7:15 PM

I was making one called Meridian which was a rather poor attempt at invoking callbacks at certain times

It had iso8601 timestamps and fully qualified java references in a config file to determine what to invoke & when

never really saw the light of day cus it was pretty awkward to use

Simon André Forsberg

Seems like my plugin is still out there, don't know if it works with the recent Bukkit versions though: curse.com/bukkit-plugins/minecraft/creepermess

@SimonAndréForsberg did you happen to hook it up to MCStats? e: nope. aww, stats would've been neat.

I was going to make a website for Minecraft, actually, but it just felt like I was re-inventing the wheel, so I didn't

was going to do something with html5 canvas and region files

but then i realized a) it's already been done and b) just how memory intensive that would be to be done in Ruby

at the very least you would be dealing with 21 * 21 * (16 * 16 * 256) blocks

@RubberDuck the more I think of it, the more I think I should make SqlCommand a static class

obviously it might have been better to implement frustum culling but even the memory usage alone would make the project unviable imo

7:19 PM

@Mat'sMug A module or a default instance?

I wouldn't use a default instance.

Simon André Forsberg

@Schism Nope, barely even knew about MCStats back then

Then again... VB6 is single threaded, so it might be ok.

the problem with a VBA module, is that any public function becomes visible as an Excel formula

Not sure.

@Mat'sMug And there's that.

default instance is what I want :)

7:20 PM

Q: AngularJS - Google logout directive

Our application needed a function to sign out of Google. Unfortunately, there is no such API and I was forced to use an iframe to: http://accounts.google.com/Logout and a polling mechanism to see when the operation is complete. I had a lot of doubts whether to put this code in a directive or in ...

So...... I'm thinking that since we're more than likely going to use a network drive for a repository, SVN might be the way to go. Thoughts?

Q: Push git changes to a shared network drive

How can a team of four people use Git (specifically Github for Windows) to push local changes to a shared network drive? Right now (without Git) we have to copy the files from the network drive to our local machine, edit the files, and then re-upload them to the shared network drive. This is a ...

git networking push shared drive

^

Basically it

Simon André Forsberg

That looks easy enough...

I did that with my MVC project to get it hosted on our inhouse dev server

it is! surprisingly

You don't have to use a bare repository but git will scream at you if you don't

Simon André Forsberg

It looks so simple I should have actually been able to figure it out myself

the trickiest part will be getting the absolute network url and setting that as the remote url

git init --bare
cd /your/local/git/repo
git remote add inhouse X:/path/to/bare.git

...wait i fked up

after that you can just treat it like a normal repository

7:35 PM

Okay then. I won't mention SVN at all. I'll recommend either going with bitbucket or using a network drive.

Thanks guys.

np. bitbucket's cool I gues

i need to remember you can edit your posts, damn

Uh

isn't there a shortcut in eclipse for a quick fix or something

like with resharper in visual studio if you get red line of death you can press ctrl-space and get a context menu to choose an appropriate action to fix the issue (i.e, 'move to new namespace', 'resolve X class from Y namespace')

Ctrl+1 nvm

Simon André Forsberg

@DanPantry I normally simply use F2

f2 is javadoc on my pc

I just changed it to ctrl+space, every other keybinding so far is how I remember it in visual studio

Simon André Forsberg

It is Javadoc as long as there's not a compiler error there

ctrl+# for commit for example :) but that sucks because it doesn't seem to work while you have focused the source window

Simon André Forsberg

7:39 PM

ctrl + space is autocomplete...

not any more it isn't :D

Simon André Forsberg

oh well

autocomplete is tab for me

Huh. maven didn't recognize my test
