@IngoBürk You can practically say that on most questions here. Stack overflow isn't only a 'my code doesnt work - fix it' site. And I'm not asking for a code review. I'm asking for a different way to do something(concept) and the code is simply an example. — Amir Popovich 39 secs ago

@blaizor Thanks - Monkeys like stars.

Monking to all.

It is 07:48 on Sunday morning for me, there are no posts in review queues, there are no flags, and there are no issues in my inbox....

... all is well on Code Review.

Andddd..... someone processed the one-vote-short query ;-)

Thanks santa!

Busy day today... Superbike, MotoGP and Formula 1 to watch

@rolfl Sounds like all is good to go back to bed :P

rolfl

Yup.... all is so good I may just get out of bed ;-)

skiwi

Ah... still in bed

rolfl

For the first time in months I got more than 8 hrs. sleep, and I scored 9.5

skiwi

Wow

I scored... 8.5 also quite good

Won't be hitting that much anymore soon in the coming weeks

someone called my name?

yep. you're welcome. i knew monkeys liked something that was yellow... at first i thought banana, but then i remembered: star

skiwi

12:08

@blaizor LOL

blaizor

is it the spirit of CR to answer your own question? ie. review your own code?

skiwi

nice one

blaizor

Answer your own question – share your knowledge, Q&A-style

its tempting

is it in the spirit of CR to take a question that i asked in a chatroom and use it was a meta question?

skiwi

@rolfl You've been more into frontend lately? Or were the new technologies you've worked with meant for backend

StackMonkey

@MudboyZh That's great; you're welcome. Now that your code works, you might want to submit it to codereview. I suspect there are some improvements that could be made to it, but improvements to working code are out of scope here. CR might be able to help. — Wayne Conrad 21 secs ago

rolfl

13:03

@skiwi at work I have been involved with a project involving.... hadoop, apache-spark, scala, java, javascript, and the d3 library, as well as clusters of machines on linux. It is a 'full stack' thing.

I found I needed to at least understand the javascript/d3 side of things, and it tied in well with @Simon's idea for the scalability best-fit problem.

So, yes, I have been doing more frontend stuff.

As it happens, a lot of the javascript suff is going to be run on both the front, and back end.

python beginner game python3 graphics

nhgrif

Hmm?

blaizor

is he asking us to correct his work implying it is incorrect and broken?

"I would be very happy if you would correct my first steps to game programming:"

well i could correct his first mistake - using python

nhgrif

13:16

The existence of mistakes doesn't at all imply broken code.

rolfl

The question appears to be very reasonable to me.

blaizor

no, i mean the way that he says it

im not saying it isnt reasonable. but i cant tell if he knows if its reasonable or not

nhgrif

huh?

blaizor

is he having problems with it executing properly?

i dont want to review and then he tell me that it doesnt work how he wanted

nhgrif

If you have a high suspiscion that it's broken, leave a comment asking.

I don't gather that from the plain English part of the question, and I can't make an assessment of that based on the code--I don't know Python.

I'm not entirely certain the graphics tag is appropriate however.

blaizor

13:19

mmm true

but if it isnt, what questions are being tagged on CR that are appropriate for it?

nhgrif

codereview.stackexchange.com/questions/tagged/graphics

blaizor

im already there haha

nhgrif

Again, I don't know Python, but it seems his code is just simply adding a basic button to the screen, right?

blaizor

yeah i guess

nhgrif

So, user-interface

blaizor

13:21

i havent read it yet

yeah. adds a button to the screen, handles on click and on release

ok we have confirmation that the code works

nhgrif

@blaizor What languages do you know best?

blaizor

um

in order

as3, xml, java, python, html5

and then a load of crap like shell languages, FORTRAN, stata

nhgrif

So, you're relatively new to programming? I just read an answer where you suggested you weren't very good with Java.

(It's fine... I'm not trying to be insulting, just curious)

blaizor

i can use java

im just not very confident because ive never produced anything noteworthy

im relatively new to actual programming yeah, i guess

id probably put python ahead of java actually. ive only ever used java in android studio :P

honestly, i just learn languages for no reason

moving onto C# as soon as VS decides it wants to open for me

nhgrif

That's good (learning lots of languages).

blaizor

13:33

i want something useful

nothing is useful

nhgrif

Uh, well, okay.

blaizor

but im not really sure what useful is yet

nhgrif

I'd say Java is useful. Python maybe is, I don't know. I don't know who really writes Python or what it's used for.

blaizor

im a long time as3 programmer, but its pretty... easy

nhgrif

Java, C#, Objective-C, C++ are all useful.

Swift will be in that group soon enough.

C is useful. SQL is useful.

blaizor

13:34

wtf is swift?

nhgrif

Relatively new programming language.

blaizor

and, let me guess

nhgrif

developer.apple.com/swift

blaizor

it does everything, but not very well

nhgrif

Swift is amazing... it's just got to compete with Objective-C.

blaizor

13:35

or its useful for two things, except java does those two things better

ew apple

already turned away for good

nhgrif

As far as I know, Java does nothing better than Swift.

Welp, good. I can see how we'll get along.

blaizor

java is said to be more than it is

nhgrif

Watch this video:

developer.apple.com/videos/wwdc/2014/#408

blaizor

yeah its 11:38pm and i see the word "playground". that sounds fun

but really i need to sleep at some point soon

also im busy not watching bullshit

nhgrif

All right.

blaizor

13:39

haha it says i have to use safari to watch it

nhgrif

Then base your opinions on what is and isn't useful and what is and isn't a good tool based upon... bullshit, I guess?

blaizor

thats mean

nhgrif

Because you just completely wrote off an entire programming language without knowing anything about it.

blaizor

no

i know one thing about it

its by and for apple

nhgrif

And that's a pretty stupid reason.

blaizor

13:41

i agree

nhgrif

Here. 4 minutes and on YouTube.

blaizor

13:43

my favourite

JaDogg

Holy cow, that's pretty cool

nhgrif

Yes, exactly.

I managed to earn the silver ios badge last night on Code Review apparently.

blaizor

ok. its beautiful. but all i could think was how hard is it to get those graphics goin that smooth

i think there was a bit of...

SirPython

@nhgrif Congrats

blaizor

trickery, in that video

im tricked into thinking its easy then i realise later that its so. fuckin. hard.

nhgrif

13:49

@blaizor They spent a lot of time writing the code before the on-stage demonstration, yes.

But the point is, you can see the graphics update live as you change code.

Which means it'd be easier to get write in Swift than anything else.

Writing that code isn't super easy in any language...

blaizor

are you using swift in a project currently?

nhgrif

Not currently, but I have written an in-house Swift app before.

blaizor

alright

what languages do you know best?

nhgrif

Currently, in my day job I'm a .NET/SQL developer, but I also do iOS apps for work.

And I just took a job as a senior iOS dev elsewhere.

blaizor

i dont understand the significance of .NET

nhgrif

13:51

I know Objective-C, Swift, and SQL best probably. But I'm also quite comfortable with Java, VB.NET, C++, C, and C# (I just don't know them quite as well, or in the case of some, don't actuallyy develop products with them).

I also know Powershell and other UNIX shell scipting languages

blaizor

wikipedia. .NET framework. finally, i shall be enlightened

nhgrif

I know VB pretty well actually, I guess.

My current day job entails writing ERP software in VB.NET and MSSQL

blaizor

in one sentence, whats so good about .NET?

JaDogg

@nhgrif I use python a lot at work

nhgrif

I don't know. Ask @JeroenVannevel probably. He's the one that uber biasedly prefers C# and trashes literally everything else.

blaizor

13:55

:D i dont go to work

nhgrif

@JaDogg What do you do in Python? Web-based stuff?

blaizor

ok looking at wikipedia made me understand even less

nhgrif

I guess, probably the best thing about .NET is a) the DLLs work super easily with each other, b) it makes it extraordinarily easy to do Windows things.

blaizor

ah, so you go both ways?

heh heh.......

nhgrif

I don't have a preference.

blaizor

13:58

by that, i mean windows and apple products (OS X and iOS)

nhgrif

And when you don't have a preference, you vastly widen your job opportunities.

If my attitude were "Ew, Apple" and therefore I'd never learn Objective-C/Swift and iOS development, I wouldn't get the job I'll be starting in June-ish.

blaizor

i hope that by the time i finish school, mac and windows will combine and the carnage will be over

JaDogg

@nhgrif Not web. They are used for continues integration

blaizor

its a big hope...

nhgrif

And if my attitude were "Apple only!", I wouldn't have the job I have now.

Mac & Windows won't combine.

blaizor

13:59

i know :(

Well, not directly anyway.

But if it's not made clear to the user that this isn't the way to ask a question, then he just posts his question/answer as is to Code Review, which would still be way wrong.

blaizor

@Raphael And that's now how you ask questions on Code Review. — nhgrif 15 secs ago

i think he is rep farming; he found out something, then decided he'd ask that specific question and answer it himself for upvotes

JaDogg

@blaizor lol

blaizor

spelling error, nhgrif. you said "now" instead of not

@nhgrif

nhgrif

There's actually nothing wrong with that... and I wouldn't consider it rep-farming.

blaizor

yeah, thats the whole ideology behind Answer your own question - share your knowledge Q&A style

nhgrif

14:12

His question would be perfectly fine if it weren't so unclear.

blaizor

i just think he did it wrong, because it isnt going to help anyone in my opinion, or they wont find it due to the lack of details

nhgrif

btw, the company I'll be working for in June:

blaizor

@StackMonkey did a good job. i wonder if anything special happens if you tag him

nope. no special reply or anything

nhgrif

No, nothing.

He pretty much exists purely for us to get an advanced warning on people recommending questions to Code Review.

And then shut them down.

Incurrence

14:15

@SirPython Hello

blaizor

well he should have some extra functionality

@StackMonkey FACT!

nhgrif

blaizor

should make him reply with a random fact about monkeys

Incurrence

Are there more people in the chat than normal here?

blaizor

yeah its on @rolfl 's profile. ive already checked it out

JaDogg

14:16

@nhgrif Congrats

nhgrif

@Incurrence Not necessarily.

JaDogg

@Incurrence Not enough

Incurrence

@nhgrif What I mean to ask is, there seems to be a change to chat functionality, but I might be wrong

nhgrif

I don't think so.

Incurrence

I think when a computer is on, it updates the 'seen' on the profile frequently, and kicks you if the 'seen' (1 hr ago for example) is excessive

nhgrif

14:18

I never realized how close in rep I was to @RubberDuck ...

Also, I never realized that @Hosch250 has been a CR member longer than I have...

Incurrence

Mathematics chat has 39 users online, with probably 15 of them seen 6h or longer ago, so it seems atleast there, we have a change in chat functionality. Normally we have 12-15 members online

blaizor

@StackMonkey should also be able to provide facts on different users

nhgrif

It's never worked like that here.

blaizor

@StackMonkey should also be able to tell jokes

but not just any jokes

jokes written in code

nhgrif

Everyone should go find an Objective-C answer of mine that you've not upvoted and go upvote it... I'm 293 upvotes away from the gold badge (still need 42 more answers also)... and, I also need to catch up to RubberDuck in rep.

Incurrence

@nhgrif You can get banned(on main) for saying such things in Math stack chat, is that not the case here?

blaizor

14:25

the above is a synopsis of a much longer presentation. are they trying to drive away customers, or does it come naturally?

nhgrif

It was a joke.

If it makes you feel better, I can delete it.

blaizor

i hope you're talking about joining this company

nope, you're talking about your inappropriate plead for upvotes

nhgrif

Oh, wait, it's too late for me to delete actually.

@blaizor What's your deal...?

blaizor

not too late for us to flag though

JaDogg

Wouldn't it be easier to post a link to an answer

blaizor

14:28

@nhgrif i dunno. what isnt your deal?

Incurrence

@nhgrif Oh I don't mind, I was just wondering

nhgrif

@blaizor So... you haven't been "inappropriately pleaing for upvotes"?

blaizor

no, i never said i havent been

Incurrence

We had ~10 users with 80-180k rep and higher banned for a year recently - for serial upvoting each-other

blaizor

nhgrif

14:29

@blaizor Every company has some sort of manifesto or whatever. What company did you say you write code for?

blaizor

you know what they say

put a number next to someones username and they'll do anything to make it bigger

JaDogg

That's what I said post a question/answer to chat others will upvote it if it seems worthy

Incurrence

Indeed

blaizor

@nhgrif i dont

im in high school

:D

Incurrence

I wish I knew how to code

blaizor

14:31

its not that much of a wish

Incurrence

I wish I had time to learn how to code

nhgrif

@Incurrence It's pretty easy to learn. We've helped plenty of people learn how to learn here.

JaDogg

@Incurrence gnu.org/software/octave and haskell.org

blaizor

learn how to learn? sneakily put

Incurrence

@JaDogg They both seem math related, coincidence or personalisation?

JaDogg

14:34

I thought you'd like them

Incurrence

They do look nice, thanks!

nhgrif

Well... every programming language is going to have some math relation...

blaizor

yeah its one of the fundamentals

Incurrence

Well yes, but they immediately refer to numerical solutions

nhgrif

I've never heard of Octave... and it seems like we don't have many Haskell reviewers here.

blaizor

14:34

we have a few, though

Incurrence

I can code in matlab to some extent

JaDogg

Octave is kind of a clone of matlab

nhgrif

If you want to lean on Code Review for help, I'd recommend C#, Java, Objective-C/Swift.

JaDogg

Bye, I'm going to watch some cartoons

nhgrif

or perhaps C++.

Incurrence

14:36

@JaDogg Enjoy

What about Python?

Also I have heard bad things, but what about PHP

blaizor

@Incurrence if you learn C#, i'll learn it too. we can have challenges later on writing programs and submitting to CR

Incurrence

@blaizor xD

nhgrif

I'd recommend against PHP as a learning language, I think. It will probably teach too many bad habits.

Incurrence

@blaizor I don't have much free time these days, but when the semester ends xD

blaizor

you dont need that much free time

Incurrence

14:38

I have done over 11 hours of study since I woke

blaizor

i do all of my programming from 9 - 5

Incurrence

and now I am taking a break

blaizor

9pm to 5am, that is

nhgrif

We do seem to have lots of Python questions. I don't know for certain how many good Python reviewers we have or how active they are--I don't follow Python tag at all.

blaizor

i could probably jump in as a reviewer for python but tbh havent used it that much in a while so

what about ruby as a math language?

Q: What programming languages do mathematicians use?

nhgrif

14:40

I don't know. I know nothing about Ruby... but I intend to start learning it. It's what my new company uses for backends.

Incurrence

I don't have grad students yet

Haskell sounds like the way to go

If it truly is ' computable category theory '

blaizor

what about R?

Incurrence

R is for pretty statistics

blaizor

it looks nice

Incurrence

Not a programming language really

It's sort of like what I have been told HTTP is

Not a code, just a way of representing things

blaizor

14:42

honestly, i recommend python

ill dig for the tutorial i did whenever i learnt it (last year some time)

nhgrif

@Incurrence What OS are you on? Windows/Linux/OSX?

Incurrence

Windows 7

blaizor

this is it www.codecademy.com/tracks/python

it was really good

nhgrif

And what would your primary interest in programming be? Are you truly just interested in writing some code that can calculate some math stuffs for you? Or do you want to be able to actually write actual programs at some point?

Incurrence

@nhgrif Actual programs for fun

@nhgrif But rendering would be nice

nhgrif

14:45

Then I'd recommend C# or C++.

blaizor

c# it is

nhgrif

Once you learn one, learning others is easy. But those would be good starting languages.

Incurrence

I'll check them out, thanks, I might sleep now(12:46AM Australia), so I'll likely come back and talk later this week(I am always online on math chat regardless)

blaizor

i agree that learning one language makes the rest easy

Or, @Incurrence, if you have an Android device, you might check out Java as you'll eventually be able to use it to make apps for your phone.

@nhgrif If I had any time, we could start a race, but I don't, so we won't.

No, we're racing.

Just kidding... I don't really care.

My rep is too dependent upon on-topic questions being posted in Objective-C/Swift.

I am working on an answer to an Objective-C question right now though.

rolfl

14:55

You could always answer Javascript questions if you wanted opportunity... lots of those

nhgrif

Uh, no.

But I do answer the occasional easy C++/Java/C# question when I see them.

And I typically get more rep for those than anything else.

Is there a way to see how many gold tag badges there are out on Code Review?
