I usually test everything on Chrome because it has the best dev tools.. guess IE is useful for something

Q: Unordered (hash) map for C

I am still working on basic data structures for C. Now I came up with a hash map: unordered_map.h: #ifndef UNORDERED_MAP_H #define UNORDERED_MAP_H #include <stdlib.h> #include <stdbool.h> #ifdef __cplusplus extern "C" { #endif typedef struct unordered_map_t unordered_map_t; ...

Q: Using bind instead of promises or stacked callbacks

I've seen tutorials about node promises and such but not using bind. I feel like I can do lots of things this way and keep everything clean: Updater.prototype.generateLocFieldForDocs = function(docs) { console.log('list obtained') async.eachLimit(docs, 10, this.generateLocFieldForDoc.bind(th...

javascript node.js

Dan Pantry

@IsmaelMiguel no, but from what I understand some of its browser support is pretty poor going by caniuse.com

Ismael Miguel

Because it's old

And was ruined when Opera decided to use Blink

Dan Pantry

I used ye old Opera years ago

Ismael Miguel

09:06

I used it until 2014

I had to switch to IE

Opera became incredibly slow on Facebook

Dan Pantry

Actually, Opera isn't that bad compared to IE and even Firefox

but Opera mini is awful

Ismael Miguel

Opera mini was discontinued, I believe

Dan Pantry

Makes sense, it was the BlackBerry browser as far as I remember

Ismael Miguel

And used on old Nokias, as the default alternative browser

Dan Pantry

The 2.7% on IE8/IE9 :-(

Ismael Miguel

09:10

It is the default browser

On my Android tablet, I use the non-Chrome default browser

Dan Pantry

on my iPhone I use a version of Chrome that has Ad-block

iOS Safari is just awful at everything else

Ismael Miguel

Safari is the IE on Mac

Dan Pantry

there are so many web pges that have ads that rediret you to the iPhone store it's infuriating

Ismael Miguel

Someone didn't though it through

Dan Pantry

someone just raised a help desk call in my company and the reason was this:

> Q3: Reason? Came back from "pregnancy"

(quotes theirs)

Ismael Miguel

09:12

o.O

What in the world....!?

Amelia

@DanPantry we have a company blog which is "gems from the help desk"

Dan Pantry

@Amelia /r/talesfromtechsupport style?

Amelia

@DanPantry yes

Ismael Miguel

I don't have such things

Dan Pantry

So where can I apply?

I kid :-)

Amelia

09:13

@DanPantry lol

2

Dan Pantry

@IsmaelMiguel I work for a global company so we need a help desk for internal calls :\

Ismael Miguel

But I've wasted almost 2 hours on a trip to re-attach a screen and a network cable

Dan Pantry

lol

2

Ismael Miguel

@DanPantry Where I work is just me, my boss and his wife

Amelia

My favourite was the guy calling the help desk to ask about a fridge installation and why they had a bigger freezer than fridge in an office on the other side of the planet. The bloody thing was upside down.

Dan Pantry

09:14

@Amelia i'm fascinated by the fact that an employee called your help desk about a fridge

Ismael Miguel

They placed a fridge upside down?

Amelia

@IsmaelMiguel it's not even easy to do that; the bloody thing almost falls over if upside down because the top is bloody rounded

Dan Pantry

lol

2

Amelia

They literally spent 30 minutes balancing a fridge upside down, then called the help desk and complained

Ismael Miguel

Holy mother of God!

Dan Pantry

09:15

There's no cure for human stupidity

Ismael Miguel

What is wrong with people?

Dan Pantry

Not that i'm calling those employees stupid, it was probably monday morning sickness.

Amelia

Clearly

Ismael Miguel

Yeah......

Amelia

The correct diagnosis was "not drunk enough yet"

4

Ismael Miguel

09:16

The brain stopped working

Drunk?

Dan Pantry

@Amelia Ha

Ismael Miguel

I've never been drunk

Dan Pantry

@IsmaelMiguel its an unwritten rule that to do any DIY you have to be inebriated.

Ismael Miguel

I wonder how it feels like

Amelia

@DanPantry "Hey guys, watch this"

Dan Pantry

09:17

I don't drink, either, but apparently thats one of the rules in the 'lad bible'

@Amelia "hold my beer"

Ismael Miguel

@DanPantry I always do it sober

@DanPantry I would never give my beer to anyone

I just drink it all

Dan Pantry

> I've never been drunk
> No one is getting my beer

@Amelia how do you work on Osu!? just moderation?

Ismael Miguel

Yeah, I've never been drunk

But beer is sacred

Dan Pantry

my ex was in the top ~2000 on Osu!Mania in the UK

@IsmaelMiguel s/sacret/sacred

Ismael Miguel

That?

Amelia

09:19

@DanPantry ex-developer

Dan Pantry

Just wanted to make sure I wasn't missing something

@Amelia oh, apologies, I just checked your profile and assumed you were a mod on the forums or something

Amelia

Technically still one

osu.ppy.sh/u/Chitose

I still have mod powers

devs stay developers, because it's not like we don't know literally everything secret about the game anymore when we leave

I created the osu-web repo

Dan Pantry

@Amelia what exactly is there secret about a game where you press buttons? aside from private keys, but its not like you'll know those by heart

Amelia

@DanPantry the entire anti-cheat system, source code, architecture, everything that goes on in private rooms

Anyways, I originally made github.com/ppy/osu-web (which is why it's in Laravel :p)

Dan Pantry

@Amelia I never realized Osu! was private source

I don't know why I assumed it wasn't

Amelia

09:22

@DanPantry it's being open-sourced

Dan Pantry

checks first commit

> Showing 737 changed files with 33,614 additions and 0 deletions

lol

2

Amelia

@DanPantry used to be closed source, old history was 800 commits from me, 200 from peppy, 300ish from nanaya

Dan Pantry

@Amelia didn't use git or didnt want to keep the old history public?

Amelia

old history has amazon s3 keys in

Dan Pantry

I can see how this might be a problem.

i suppose when you're at 1300 commits, git filter-branch and/or git rebase becomes a bit.. out of the question

Amelia

09:26

that and github's reflog isn't cleaned when force-pushing

You need to contact github to get them to do that

If you know the commit hash, you can find old commits after force-pushing

Dan Pantry

Q: Observable collection async update

Is it good solution for updating ObservableCollection? Are there any dangers hiding in this code? namespace WpfApplication142 { /// <summary> /// Interaction logic for MainWindow.xaml /// </summary> public partial class MainWindow : Window { public MainWindow() ...

c# wpf

Ismael Miguel

Polyglot

The code was for everybody, not specifically for you

But there's no way to split message blocks

Dan Pantry

09:39

@IsmaelMiguel please god no

Ismael Miguel

Why...?

Dan Pantry

$window['Array']['filter']['constructor']('alert(arguments[0]);');

that scares me

Ismael Miguel

That creates a new function

I will try something else that doesn't scare PHP

Amelia

@IsmaelMiguel I have seen a lot of PHP in my lifetime. Good luck scaring me.

Ismael Miguel

if('\0' == "\0")
{
  $show_msg=function(){alert(arguments[0]);};

}

There

@Amelia Don't test me...

Amelia

09:42

@IsmaelMiguel Do it

Dan Pantry

I'm going to assume alert is a PHP function and isn't doing some kind of nasty voodoo to invoke javascript's alert on the browser side

I havent' done PHP in so long

Ismael Miguel

<?for($s=str_repeat(' ',$n).$s;$i++<strlen($s)+$n;sleep(1))echo substr($s,$i,$n),'
';

Dan Pantry

Not that I miss it, because I don't

sleep(1) in a loop

wat

Ismael Miguel

@DanPantry Actually, it is a neat trick. PHP won't 'interprep' escape sequences inside 'single quotes'

Javascript does.

And so, it gives the same variable 2 different values, based on the language

Dan Pantry

neat trick should be synonymous with "hack"

Ismael Miguel

09:45

@DanPantry That was for a PPCG question. Using that gave me -10 on the score (lower is better)

It's a neat trick

Dan Pantry

It is a neat trick, but I wouldn't want to see it in my code

Amelia

@IsmaelMiguel does that segfault?

Ismael Miguel

@Amelia No

@DanPantry And you won't

Amelia

@IsmaelMiguel it crashed 3v4l.org

@DanPantry "hack" might be an understatement

Ismael Miguel

I forgot to mention that it is to run on PHP4.1

SuperBiasedMan

Not sure if that means example code in that question

Amelia

@IsmaelMiguel then never mind

I run on PHP 5.6 or higher :p

Ismael Miguel

A: Fake Marquee Text

PHP4.1, 85-10 bytes Yes, this is a very old version, but it has a functionality I need. You can still run it in any more recent versions of PHP, but you need to set the variables yourself before running the code below. That helps me to reduce the size of my code a lot! It is really basic: <?f...

There

Dan Pantry

@SuperBiasedMan looks like an MVE

Ismael Miguel

09:47

It has a polyglot to test the code (you can copy the polyglot into a PHP interpreter or a Javascript console)

SuperBiasedMan

@DanPantry Minimal Verifiable Example, right?

Dan Pantry

@SuperBiasedMan yes

(MVEs are off-topic at CR)

or at least as far as I remember

Ismael Miguel

@Amelia Scared enough?

Amelia

@IsmaelMiguel nope

Ismael Miguel

<?for($H=-1;$H++<23;)echo$H?",
'":"'",$H=str_pad($H,2,0,0),":00',
'$H:30'";

SuperBiasedMan

09:50

@DanPantry I'd assume they're at least borderline, and this one definitely seems over the line as a very stubby-like one.

Dan Pantry

@SuperBiasedMan (from meta)

Ismael Miguel

@Amelia Can we move this to The nth monitor? There's site business going on.

@IsmaelMiguel I have work to do

Ismael Miguel

There's lots of PHP on my PPCG profile.

Q: Finding Euclidean Distance in c++.

I would like to create a c++ program that can help me to find the euclidean distance between 2 randomized vectors. This is what i got so far.This program can run but still fail to give me the correct answer. I hope someone could point out my mistake. Thank you in advance! #include <stdio.h> #in...

Q: Is this piece of C++ truly standards compliant?

To "entertain" some students I advise, I have written the following piece of code: /* This is valid C++ */ auto main() -> decltype('O.o') try <%[O_O = 0b0]<% http://codereview.stackexchange.com/questions/102581 typedef struct o O; o*(*((&&o(o*o))<:'o':>))(o*o); if(O*O = decltype(0'0[o(0)](0))(0)...

c++ c++14

Morwenn

@CaptainObvious Broken code: "This program can run but still fail to give me the correct answer".

Ismael Miguel

@CaptainObvious I would say that this is off-topic

SuperBiasedMan

@IsmaelMiguel What reason?

Ismael Miguel

Code Review is meant to improve readability and maintainability and everything related to make the life easier to the programmer

That code, is totally the oposite

And the asker just wants to know if it is compliant or not

He doesn't want a code review

I know that minified, golfed and obfuscated code is off-topic

Jeroen Vannevel

Just because he's interested in different things than you are, doesn't make it not a CR

SuperBiasedMan

10:19

Hm. I don't know C++ at all so I'll refrain from getting involved.

Ismael Miguel

That code is bolderline, in my opinion, with obfuscation

Have you seen his comment?

If it was clear, you wouldn't need to ask why the URL was there

(I wondered the same too, and was about to vote to close as a duplicate until I noticed the difference)

Dan Pantry

@IsmaelMiguel he didn't make a comment. @Morwenn and @SuperBiasedMan have made a comment

Ismael Miguel

@SuperBiasedMan That's a label followed by a comment. — Morwenn 6 mins ago

This comment

Oh...

Dan Pantry

was made by @Morwenn

lol

(sorry for the tags Morwenn..)

Ismael Miguel

... Right ...

Morwenn

10:22

No problem :p

Ismael Miguel

But still, the code isn't clear

Dan Pantry

@IsmaelMiguel I'm pretty sure the intention of that question is produce code that isn't clear, but standards compliant.

Morwenn

On the other hand, it's made to be obfuscated.

Ismael Miguel

That's off-topic

Morwenn

But Code Review might be a good fit for standard compliance.

Dan Pantry

10:23

Code that isn't clear to enough to be reviewed is off-topic.

Jeroen Vannevel

Standard compliance is a valid question imo

Dan Pantry

However, the code is purposefully made to be unclear.

As long as he states that he doesn't care about clarity and/or he wants the code to be unclear, I think its' fine.

Ismael Miguel

Minified code as well, and it is off-topic

Dan Pantry

If you feel strongly about it, VTC

But I think it's fine, and apparently so do Morwenn and Jeroen

The goal of that code is to be unclear, and it says that in the question. OP is asking for a review based on standards compliance.

Ismael Miguel

How can you review it if you can't read?

Dan Pantry

10:25

questions that are unclear are off-topic, but unclear code is not.

Morwenn

@IsmaelMiguel I can read it.

Dan Pantry

If we turned away code that we could not read we would be out of a job

Ismael Miguel

@Morwenn I can't.

Dan Pantry

@IsmaelMiguel then don't review it.

Jeroen Vannevel

@IsmaelMiguel You have no experience in the C++ tag either

Dan Pantry

10:26

Now, the only thing I am on-edge about is that OP doesn't explain what his code should do.

Ismael Miguel

@DanPantry One thing is not being able to due to lack of knowledge. Other is due to the lack of clarity in the code.

Dan Pantry

@IsmaelMiguel this question is clearly meant to challenge people who have a lack of knowledge.

Morwenn

@DanPantry Compile while being unreadable. And it achieves its goal.

Dan Pantry

@Morwenn he actually expanded on that, too

Ismael Miguel

For challenges, theres PPCG

Mast

10:27

@SuperBiasedMan They're example code.

Dan Pantry

This is not a challenge.

This is a piece of code that he wants reviewed about whether or not it is standards compliant.

yes, the code is unclear. That's the purpose of the code. It is intentionally strange looking, but it compiles.

Mast

@DanPantry That's off-topic.

Ismael Miguel

Alright

So, obfuscated code is on-topic

Mast

Let me throw the on-topic page at you.

Do I want the code to be good code? (i.e. not code-golfing, obfuscation, or similar)

Dan Pantry

Okay, then I'm wrong.

The xkcd Survey: Big Data for a Big Planet

Dan Pantry

However, I challenge the assertion that it is off-topic because it isn't 'clear'

Just because the code in a question is unclear doesn't mean that the question is off topic.

Now, if the question is unclear in what it is asking, well, that's a close reason.

There is nothing unclear about this question. The code, however, is obfuscated, and as @mast correctly pointed out is off topic

Ismael Miguel

Wow, I got an error that the message is too long

I'm voting to close this question as off-topic because on the on-topic help section ("What questions are on-topic for this site?") one of the points of the on-topicness isn't fulfilled. Quoting: "Do I want the code to be good code? (i.e. not code-golfing, obfuscation, or similar)" isn't fulfilled and therefore, as per the documentation: "If you answered "yes" to all the above questions, your question is on-topic for Code Review.", but the refered question would have an answered with a "No", making this off-topic. — Ismael Miguel 1 min ago

You don't want to tell a story in comments.

You want to tell what's wrong and just that.

Keep it civil, keep it short.

@IsmaelMiguel Yes, you could.

How? I can delete and re-write it

Mast

@Morwenn I agree it's an interesting question, but it's not on-topic IIRC.
