The Nineteenth Byte

maybe one goat challenge was enough though

What was the first goat challenge?

@DJMcMayhem ok

I don't think it will be very different though

@Downgoat snek is still shorter than chez :P

3:12 PM

Actually I don't think my answer will be any different

@LeakyNun Really? I thought the two digit was the hard part. Than again, I didn't implement it

@DJMcMayhem Nope. The majority of my answer is to generate the appropriate coordinates

@DJMcMayhem ;_; becus dangr noodl can diet but ches is ches

is it a good idea to post the "How to implement your KoTH submission" in a off-site text file, and simply have the core challenge on the post?

because there are different sets of instructions for different languages

Sp3000

@Mego Is that from memory, or is there a way to search these? From memory I think the first person I talked to in chat was Martin, but I honestly can't remember

3:14 PM

@DJMcMayhem generate coordinates: 24 bytes, generating initial array: 5 bytes, replacing the coordinates: 19 bytes (in which 7 bytes is used to alternate the digits)

The remaining 3 bytes are irrelevant

Dang it. I should be winning that newest encryption challenge, but I have to add 5 stupid and pointless bytes to make the output format match

A: What does "number f**king ten" mean?

ELU never ceases to amuse:

I think, in the context given in the question, it means American in a pejorative sense (see @armen-Ծիրունյան's answer), with partial rhyming slang (ten/-can). The interrogator already thinks the guy is VC, and is using language to try to get him to admit that. If the guy balks at the pejorative ...

3:24 PM

New and improved query! Your first ten messages. Don't forget to check the JavaScript option!

@El'endiaStarman feature-request auto-link the mid field

@NathanMerrill That would be awesome.

CMC: Figure out how to do that. :P

@Fatalize Done.

@Zgarb Done.

@LeakyNun The server needed a kick. One of the processes was misbehaving. It should work now.

@Dennis Please tell me you actually kicked it :D

@El'endiaStarman "http://chat.stackexchange.com/transcript/message/"+mid+"#"+mid

3:29 PM

@Poke As it is, that would be a security risk.

@Dennis how do You kick a server? ._____,

@βετѧΛєҫαγ My legs aren't long enough... (The server is in New York.)

@NathanMerrill ... -_-

@Dennis Well that's a damned shame.. :P

@Dennis you don't have to do it from your chair

3:30 PM

Well, I was actually thinking of SEDE's optional auto-linking of a few fields by putting the columns in brackets, but then realized that I don't have to implement something that awesome.

Maltysen

@Dennis they should offer kicking as a service where they make the janitor at the datacenter kick it

@NathanMerrill Still, 7,525 km is a lot of distance to cover...

Poke

@Dennis Do you go over the source of every language you pull? Why would that be a security risk

@Poke Yes, I do.

Poke

ah

3:32 PM

@El'endiaStarman the problem with auto-linking other fields is it usually means that you will have to add additional columns in the select statement

butt the mid doesn't need that

and user_id?

Yeah, I realized that I can put in the <a> tags server-side while the table's HTML is being constructed.

I can do it for U.uid too, yeah. Good idea.

user_id is the internal id, and does not correspond to the user's SE chat id.

ah

I didn't get a response earlier: does it seem like a bad idea to put the "How to implement a submission" on a .md file on github instead of the KoTH question itself?

Put it on both

@NathanMerrill I'd say do both? What do you mean by "implement a submission"?

Ninja'd

3:38 PM

well, there are two sets of instructions

One for Java submissions, one for other languages

they basically say "put your submission here, you need to input like this, output like this"

and various other details that aren't actually relevant to the "interesting" part of the challenge

My purpose is putting them offsite is to clean up the post and make it easier to read

Would you still recommend keeping it on the question?

Anonymous

A code golf challenge (or any question on any SE network site) should be self-contained

Anonymous

If the entire internet goes down except for SE (and possibly imgur for image hosting), you should be able to get enough information from the question/challenge to answer it

So, the owner of one of the servers I administrate put his private info on the whois database for his domain registration, including cell number and permanent address.

but this is a KoTH. Unless I'm going to post the entire controller, its not going to be self-contained

Anonymous

@NathanMerrill Then you just answered your own question :)

3:45 PM

@Mego ...then every KoTH would be off-topic

Anonymous

Challenges which aren't entirely self-contained (i.e. have code hosted on other sites) aren't off-topic per se. They're just vulnerable to link rot.

I agree. However, adding "implementation details" on the Controller itself doesn't add any link rot

Anonymous

gzip the code, base64-encode it, include that in the challenge, if the controller code is too big

-.-

Protecting against link rot doesn't take much effort, and it has a huge payoff

Any feedback?

Anonymous

@βετѧΛєҫαγ I think you're missing an "is"

@Syxer In major parts of the word, a service (website etc) hosted on any domain is required to have a legal imprint. That contains the address, phone number and full name. Doesn't make a difference if the WHOIS contains the same data. After all, that's what it is supposed to do.

@Mego Where?

Anonymous

But nowadays having your name, address, and cell phone number publicly available is asking for harassment

3:57 PM

@TimmyD It's a permanent address. The site isn't supposed to be related to IRL him at all.

Anonymous

> let's face it, your code nowhere near production code standards

Plus, it's an MC server

Where we ban people daily for threatening the owner

So

@Syxer censorship

don't want this place to have cancer

@uoɥʇʎPʎzɐɹC lol it's our server

@Syxer Ah, that's a different circumstance.

3:59 PM

Then he would have to use a WHOIS protection service. But that's only legal for a subset of TLDs.

They don't have a right to access

@Syxer threatening or constructively criticizing?

@Mego I'm embarrassed by it so I don't wanna share.

@uoɥʇʎPʎzɐɹC Legitimate threats

Then again, people who do that are pretty dumb

@Syxer oh, that's ok

4:00 PM

Probably wouldn't know how to use a whois lookup

Probably.

hm...

@uoɥʇʎPʎzɐɹC Don't do that.

@uoɥʇʎPʎzɐɹC Not exactly helpful if the domain name service provider wants to contact him.

@Syxer those people would probably be using website generator anyway which hide your data usually

That's one of the most stupid things to do.

4:01 PM

@uoɥʇʎPʎzɐɹC that's not good idea

Say things like "I'm a hacker, I could get in to your email and facebook and ruin your life"

As I said, most registrars offer a free WHOIS protection service for domains where such a service is legal.

And those kinds of people don't usually have strong passwords...

Providing downright false info gives the registrar and the upstream TLD seller the right to cancel you domain at any time.

ill make a language but i cant find a good name

4:02 PM

I know it's a bad idea now. no need to continue to kick a dead chicken

@ReleasingHeliumNuclei goatspin

@Syxer Just say that you'll report them to the police. They don't realize the harm they're doing...

...to themselves!

Trace their IP, scare him with the location. Dig in. Set an example. Don't back off - they think banning is a sign of weakness

@Downgoat NO

@uoɥʇʎPʎzɐɹC True.

Or ban them with a message: "If you want to threaten me with no reason, then why should I let you on my server. Find somewhere else to be an asshole."

4:08 PM

@uoɥʇʎPʎzɐɹC We do that lol

@Syxer who doesn't want to screw with an asshole for fun? It's a good bit of justice dealt. Maybe letting the threatener step back and an asshole.

> My grandad always said fight fire with fire. That's why he got thrown out of the fire brigade

@βετѧΛєҫαγ heard it before, it's always good

@Syxer I hope you implement the trace IP thing. If that doesn't work, google their username and cross-reference it until you get a name or other personal info.

Postfix it with "and that's why you don't mess with me brother"

Fatalize

@Dennis Thanks

@uoɥʇʎPʎzɐɹC Okay that's too much

4:12 PM

lol. Send me the results if you can...

There's a difference between responding to a threat responsibly and threatening back lad

or, "the only reason you threaten other people is that you know, deep down in your heart, you have little else to do but pretend to menace people."

Q: Installation and testing instructions for specific programming languages

26

Most of the answers on this site are made using programming languages, that are well known, and easily installable by most of the people. They have well known installers (or are already included) in all major PC operating systems. These includes languages like Java, Ruby or Python. Some answers ...

discussion testing

^ This question should be a wiki

(the nature of the challenge is, obviously, not going to change)

@NathanMerrill I commented

Just edited with a link :)

FYI, the controller is out of date, I'll be pushing in a bit

4:34 PM

@ASCII-only Your last minute additions had a syntax error, but it seems to be working now.

Thanks!

Mildly interesting tidbit: exactly six usernames have been used by more than one user.

In the TNB, that is, and to date.

@βετѧΛєҫαγ wat no??? Not sure how u got that

@NathanMerrill: Incidentally, this above fact means that though I'd like to auto-link usernames to their chat profiles, I can't guarantee that I link the correct one.

@El'endiaStarman well, you could, but again, you'd have to add additional stuff in the select statement

you couldn't do it with a Join, but you could always add a uid

@NathanMerrill Precisely. So I'll just settle for auto-linking uids.

Which is functionally the exact same as auto-linking mids, so that was easy. :P

4:45 PM

a=rand();b=rand(); in C is that ok

I don't know C's syntax for random but that looks fine

rand should be seeded (with srand(time(NULL))) and im asking if the code will generate two seperate random numbers

@ReleasingHeliumNuclei As long as you've seeded with srand and you don't actually need randomness, sure. rand is terrible in most implementations.

@Dennis so how do i generate random in C halp

If you only need two numbers, it's probably fine.

For what is this?

4:50 PM

if i need, say, 100 random numbers?

RFC 1149.5 specifies 4 as the standard IEEE-vetted random number.

On POSIX, there's random.

@Dennis my friend wrote some Python code, im trying to port to C

@NathanMerrill status-completed

nice!

4:52 PM

@ReleasingHeliumNuclei securecoding.cert.org/confluence/plugins/servlet/mobile#content/…

@ReleasingHeliumNuclei I thought that was the job of CPython's interpreter :P

@Dennis interesting. Thanks

@NathanMerrill source code is tl;dr

Any CMC?

CMC: generate a random number, than generate that many random numbers and print all

@ReleasingHeliumNuclei a random number in what range?

5:03 PM

if infinite range, then what distribution?

not sure which is more correct

you can't have uniformly distributed random number in ]-infinity, +infinity[

@LeakyNun [0,2^31) or [0,10]

@LeakyNun technically, we can, just not with physical memory constraints

5:05 PM

@NathanMerrill no you can't

If there's infinite choices, then each number is chosen with probability 1/infinity = 0

1/infinity is not 0

@ReleasingHeliumNuclei Pyth, 7 bytes: mO11O11

it approaches 0

Well, yes

5:06 PM

@NathanMerrill Prove us wrong by coming up with an algorithm

current = 0
while True:
    if (random.next() < .5)
        break;
    current++
if (random.next() < .5)
   return -current
return current

@NathanMerrill not uniform

CJam, 13 11 bytes: Bmr{;Bmr}%p

oh, my bad

@BusinessCat why can't pyth have 11

5:10 PM

C, 58 bytes: i;main(){while(i++<random()%11)printf("%d ",random()%11);}

@ReleasingHeliumNuclei I doubt this though I'm not sure that it isn't uniform

for bit in number:
    bit = 1 if random.next()  < .5 else 0

num = 0
k = 0
while True:
    digit = random.randint(0,9)
    num += digit * 10**(k//2 if k%2==0 else -k//2)
    k += 1
print(num)

This algorithm basically constructs an infinite sequence of digits on both sides of the decimal point.

@LeakyNun I don't know Pyth so I can't say

regardless, its not possible with actual hardware, but its mathematically possible to have a uniform random number

5:12 PM

Thanks to @NathanMerrill and @El'endiaStarman TIL.

@El'endiaStarman I just realized our algorithms are basically the same, but in different bases

What about an algorithm that halts? Is it possible?

@ReleasingHeliumNuclei Actually, 10 bytes, `4PJ`4PJ@n

no, because you are assigning to an infinite amount of memory

@NathanMerrill Pretty similar, yeah. Yours seems to pick from the integers though, whereas mine selects from the reals.

true

though, maybe my bits are bits to a infinite floating type

...not sure how that would work

5:16 PM

Yours also seems to generate finite numbers anyway (or rather, a finite number of numbers?).

I'm assuming a infinite number of bits

Both of you used an infinite number of digits (bits)

In a sense the number (cardinality) of numbers generated by @NathanMerrill is uncountable

by the diagonal argument

er, I think mine is uncountable because I never give a count

aka, you have no idea where "bits" comes from

Hmm. I think I was thrown off by the for bit in number bit.

@El'endiaStarman that would just translate to below:

number = 0
while True:
	number *= 2
	number += random()*2<1
print(number)

5:23 PM

random()*2<1 is the same byte count as random()<0.5. :P

I like integers more

@El'endiaStarman random()<.5 should be shorter

I think there may be a flaw in that you cannot have integers with infinitely many digits. Otherwise, there would be no first digit.

@El'endiaStarman which is why it is said that it is physically impossible

and instead of generating the countable set of natural numbers

@LeakyNun No no, it's mathematically impossible.

he is generating an uncountable set

5:25 PM

No first digit means that you can't order them.

so he's not really generating the natural numbers

Actually, let me amend my "mathematically impossible" statement - it's mathematically impossible given the axioms we usually work with.

I'm profiling my controller, and the results are pretty depressing:

There might be a consistent system for dealing with such "integers".

See those first 4 lines? Those all deal with communication over pipes

5:26 PM

@El'endiaStarman yes

it is akin to the 2-adic system

@El'endiaStarman you can order them by the last digit

what is impossible to order is the numbers you generated

which expands to both sides

More fun, though, is string multiplication and Invoke-Expression, but it's 36 bytes -- "Random -ma 11;"*(Random -ma 11)|iex

They function slightly differently, though. The first one will always produce at least one number, while the second has a chance of producing nothing but an error.
