The Nineteenth Byte

Actually, I'm wondering - is it possible to write some non-trivial piece of code such that Quill is guaranteed to have no problems with it? I always get the feeling that with code review, someone's bound to have a problem with something :P

Katenkyo

1:11 PM

`#define 0 "()"`
`void o0{O0;}void O0{o0;o0;}void main0{o0;}`

Quill

@Sp3000 I'm not that good :p

Sp3000

:( lies

Quill

I've had a few questions that take forever to get reviewed

Katenkyo

Oh, I found a nice one!

eval(arg[1]+"+"+(arg[2]))

Trivial, but ugly <3

Sp3000

What's arg? D:

Quill

1:15 PM

if that was javascript, I'd suggest using template strings

Katenkyo

The argument array/table

Dan Pantry

@Sp3000 Nope

Katenkyo

could be argv in C

@Quill I'm not a big fan of Javascript, so never heard of template strings, gonna check what it is ^^

Dan Pantry

@Katenkyo `foo${interpolated}bar`

const interpolated = 5

> foo5bar

That's a template string

Sp3000

I'm guessing the intended response was: 1) Needs more whitespace, 2) Why the parens on the second half? 3) Oh god eval D:

Katenkyo

1:17 PM

@DanPantry Thanks!

Dan Pantry

Though there's something to be said for @Quill reviewing golfed code :D

grc

@Quill I commented on your comments

Quill

I can't do that. Not yet, at least

Sp3000

Actually, I think there's still an art to reviewing golfed code

Katenkyo

@Sp3000 More like "3) Oh god, eval for a sum D:"

@Sp3000 i'll check if one of my lua golf would fit :D

Sp3000

1:18 PM

For example, L| in CJam (setwise union with empty list) is better than _& (intersection with self)

For deduplicating a list

somebody

@Quill i=1e300;for(;;i-->0){while(i&&alert('foo'));}

Katenkyo

> That's an essential part of my algorithm.

> Or is it..?

@grc nice review !

Well played.

1:21 PM

@Katenkyo division by zero

otherwise the program doesn't terminate

Sp3000

> Does this even fucking compile?

Comment-comment should have been "kiddy voice what's compile?"

Quill

@grc I commented on your comments on my comments

Katenkyo

@grc dividing by 0 is love :)

@Quill you said you love ternaries ? :D

b[j]=0<a[j]and a[j]or(a[j-1] or 0)>(a[j+1] or 0) and a[j-1] or(a[j+1]or 0)

Quill

Try writing that in a python ternary ;)

Katenkyo

It wouldn't work in python ternaries :)

Quill

1:26 PM

everything works in python ternaries :-)

Katenkyo

it uses the fact that in a structure (cond)?(value1):(value2), if value1 is false, then return value 2

Quill

wat, what syntax is that

Katenkyo

otherwise, it would be trivial to write down ^^

ternaries built on and&or operator ^^

somebody

@Katenkyo write it with arrays instead of and+or

Quill

@somebody gist.github.com/The-Quill/4d50a202dd05415eb5e0

Katenkyo

1:32 PM

@Quill in a python like syntax : b[j]=0<a[j]?(a[j-1]!=false?a[j-1]:0)>(a[j+1]!=false?a[j+1]:0)?a[j-1]:(a[j+1]!=f‌alse?a[j+1]:0)

Quill

python is backwards

Katenkyo

@somebody with arrays?

somebody

python doesn't have cond?a:b

Quill

> value1 if cond else value2

Katenkyo

arf, assumed it was like in C

correcting myself right now

grc

1:34 PM

@Quill I commented on your comments on my comments on your comments

somebody

@Quill for(let D=0;;D-->0)alert('foo')

Katenkyo

@Quill

b[j]=a[j] if 0<a[j] else a[j-1] if (a[j-1] if a[j-1]!=false else 0)>(a[j+1] if a[j+1]!=false else 0) else (a[j+1] if a[j+1]!=false else 0)

somebody

@Katenkyo python array ternary (not recommended) is (val1, val2)[cond-1]

Katenkyo

@somebody doesn't work in the language I made this in :)

it comes from here

It's a language that don't even allow you to do i+=1or i++

@somebody oh, for the python form ^^

When did they add the "business" link under "help" on the top bar?

Katenkyo

@PhiNotPi Same time as the "Job" feature I think

PhiNotPi

When was that?

A while back? I guess I just haven't noticed until now.

Apparently one of their programs is to "sponsor a tag" where a business gets to put their logo and sponsored links on the tag pages.

Which I don't think I've ever seen before (I turned my adblocker off to check.)

Katenkyo

I think it was some months ago

My adblocker is off too, and I feel like I'm never seeing ads anyway...

TimmyD

This site has ads?

Katenkyo

2:09 PM

@TimmyD Yes

A part of them vanish when you hit 500+ rep

And otherwise, it's still sneaky

TimmyD

Huh. I'm not sure if it's good because I didn't/don't notice them (and so they're not obtrusive), or bad because I didn't/don't notice them (and so they're not effective).

Katenkyo

Regarding SO/E's policy, it means they are good

Rainbolt

Power has been out for an hour and my entire company is still programming.

Katenkyo

@Rainbolt except you ^^

Rainbolt

Our generator is awesome!

Hey, it's been 15 minutes and I have already assigned myself a task to work on

That's a lot of effort for one morning

Katenkyo

2:15 PM

Haha, forgot some of us arrived at work right now ^^

Rainbolt

2:31 PM

Hah! Our antivirus software is preventing some of our code from compiling successfully, so they disabled it for just our team for now. I turned on ReSharper to see if it would work again, and it seems to be working fine.

Katenkyo

I don't know what's worse...

That your antivirus thinks your legit piece of code is a malware, or that your company turned it off...

Rainbolt

I've been wanting it off ever since they put it on

antivirus software is for people who can't control what they click on

2

TimmyD

For personal use, sure. In a corporate environment, it's not my clicking that I have to worry about, but my idiot coworkers' clicking. AV doesn't prevent my computer from being directly infected, it prevents their computer from infecting mine.

3

Katenkyo

TimmyD as a good point here...

TimmyD

And believe me, there's a lot of idiots in corporate America ...

Katenkyo

2:39 PM

Also, lots of people casually use their USB devices for both home and office. Lots of viruses can penetrate into your network this way

s/America/World

Roujo

'morning folks ^^

Yeah, you basically have to trust everyone on your network not to mess up. At home, you can make sure everyone has good internet hygiene and you're pretty well off. In a corporation of hundreds where I'm not in any position to teach people how to internet... I'd rather have some AV lower the risk. =P

Even if everyone is tech-savvy, it only takes a rogue download to mess up your day. And as the number of users grow, the chances of an error like that occurring by accident grow as well.

Plus, the cost can get pretty big as well - CryptoLocker on your home network will be a bad experience for a few days, depending on how you do your backups. Shut everything down and build them back up one by one.

CryptoLocker on your corporate network is going to be a whole other can of beans =P

Katenkyo

@Roujo It could get even worse when you an other company manages your servers and can't possibly be there in some hours...

Roujo

@Katenkyo Pretty much, yeah. In any case, it's out of my hands - I'll let corporate IT manage their network, since I'm not going to be the one cleaning up if it ever goes bad. =P

TimmyD

2:55 PM

@Roujo The various Crypto variants, I think, have been a good wake-up call to people that data you don't backup is data you don't care about. It's kinda sad that it takes something as drastic as Crypto to get people to realize that, though.

Katenkyo

@Roujo Sadly, in my actual position, I might have to deal with the trouble until I can get in touch with this out-site company ^^

@TimmyD Anyway, if your sysadmin doesn't have a good automated backup solution, he should be fired.

TimmyD

@Katenkyo At my previous job, I have literally had a client say "What do we need backups for? It's on the SAN!"

Katenkyo

@TimmyD That literally froze my brain...

Kevin W.

3:22 PM

@TimmyD That's the same kind of customer that would complain about system slowness when you restore a snapshot from the SAN because they refused to properly back up the data

TimmyD

Well, they were running ~2500 mailboxes on a single Exchange 2003 server with, I think, 8GB RAM at the time, so they were pretty used to "slow."

Katenkyo

@TimmyD Their sysadmin should be fired... And by that, I mean burnt to death.

Geobits

And by that, I mean by the sun.

Katenkyo

^

TimmyD

Hehehe, yeah. He was ... special ... to work with.

Katenkyo

3:30 PM

He was eating the ram as Chrome would do?

TimmyD

Thankfully, that was many years and several jobs ago, so I don't have to worry about it anymore.

Have you guys heard of the Beta function? en.wikipedia.org/wiki/Beta_function

Katenkyo

3:42 PM

I'm not a math lover, so I can't say I heard of it ^^

Sherlock9

It's a little like the gamma function, in that it's defined by an integral, but this function has two parameters instead of one. I figured I could have one or two questions on it: one based on the beta function B(x, y)when both x and y are integers, and one when x and y can be any number, including complex numbers
