The Nineteenth Byte

@mınxomaτ Related, Microsoft used to have a certification program for licensing. I don't think they do any longer.

@Riker You're not on the HTTPS site genius :P

8:16 PM

yeah, that's what I mean

it's not a https for me

3 mins ago, by mınxomaτ

But esolangs is not TLS by default.

Comrade SparklePony

that redirects to the main thing for me

manually typing https:// in front of teh url I mean

@Riker Then why would you say it doesn't have an expired cert. You wouldn't know.

oh, true

I thought it didn't because it didn't error

but yeah, it doesn't confirm either

8:17 PM

It's objectively expired: ssllabs.com/ssltest/analyze.html?d=esolangs.org

@Riker It confirms that you have a redirect that doesn't exist on the server.

what

There's no redirect on the SSL version.

maybe caching?

How the deuce do you actually view the certificate in Chrome? In IE it's as simple as right-click the padlock (or open padlock, if it's broken) and "View Certificate."

{ ~ }  » curl -I esolangs.org
curl: (60) SSL certificate problem: certificate has expired
More details here: curl.haxx.se/docs/sslcerts.html

{ ~ }  » curl -Ik esolangs.org
HTTP/1.1 302 Moved Temporarily
Server: nginx/1.6.2

Content-Type: text/html
Content-Length: 160

Notice the 302 points at TLS, not non-TLS

When in doubt, curl :). No cache, no cookies.

Given a N*N maze, and string of N,E,W,S denoting positions to move to. I need to determine how many moves are possible in sequence out of a string (containing these 4 letters only). For eg- If string is NNN ,and I can only move 1 step up,that means answer for that cell is 1. If for another cell...

Poke

@AdmBorkBork yeah i really dislike the change

i guess they think more people might click in the url bar now that non-https is marked "Not Secure"

and viewing cert details will confuse the average user

some nonsense like that

Nope. The original are all no longer active

Q: Cyclic Levenquine

Background As most PPCG regulars will know, a quine is a program which outputs its own source code when run; and the Levenshtein distance between two strings is the minimum number of insertions, deletions, and edits needed to change one string into the other. In this challenge, we're combining t...

@DJMcMayhem Huh. I'm 37th.

@Mego Deleted, actually. Letting an underage participate is not the problem; storing their email address is.

@mbomb007 I'm 34th apparently

@NewMainPosts Maybe a solution in Headsecks would be possible?

Then you could encode its source and "increment" by 8 mod 256

@mbomb007 can it go forever? does unicode have some limitation?

ASCII-only

Also yes, Unicode doesn't have infinite characters

@mbomb007 REPL answers are allowed, but they're considered a separate language. — Dennis ♦ 3 mins ago

I'm not happy with that consensus (I've downvoted it myself), but it is what it is.

(and also sounds difficult to get right as a challenge, so more in need of feedback than average)

@Dennis I haven't voted in it because I'm torn. I don't want people to golf solely in REPL, but I also thing have REPL allows for some languages to "essentially" compete in otherwise hard challenges, such as restricted-source questions

ais523

10:59 PM

@Dennis out of interest, what's your personal opinion on the subject?

I also think that there's two different sorts of REPL answers:

* the answer is typed into the REPL, and it then does I/O the way a normal program would;
* the answer is typed into the REPL, returning to the REPL prompt; the user input is also then input at the REPL prompt (i.e. the answer changes the REPL into a solution to the challenge)

I'm not sure if we're drawing a distinction at the moment

@ais523 Hard to say. Some languages exist solely as REPLs, so we'd probably need an exception for those. But if a language can be invoked as a full program or supports functions, REPL answers in that language shouldn't be allowed imho.

ais523

hmm, there are edge cases even to that, like Prolog

luckily it supports functions

but it doesn't really support full programs; you can simulate them by writing custom initialisation code and then crashing the program during it, so that the REPL part of it never gets to run, but I'm not sure that counts

I won't pretend having the slightest clue about Prolog.

@ais523 At least swipl seems to support programs though. github.com/TryItOnline/arena-server/blob/master/wrappers/…

ais523

11:14 PM

that appears to be a REPL: Try it online!

you can see that the input here is a Prolog program that calls a function, not something like a string or an integer

or I guess it's a REP, because it only runs the command specified, rather than asking for another

@DJMcMayhem @BrainFlakUsers - I'm writing an article on brain-flak. How do I output something? >_> I tried running this, which of course outputted nothing.

What are you trying to output?

0 '

@ConorO'Brien There is no explicit output functionality in Brain-Flak. At the end of the program execution all the contents of the active stack are printed starting at the top

11:23 PM

({}) prints 0.

@ConorO'Brien Woah, cool! What are you writing it for?

Also, like others have said, to print something, push it onto the active stack

Timtech

@Dennis Why exactly was I tagged in that? Just wondering

I think that all of my posted TI-Basic scripts are full programs

Because you cast one of the delete votes.

@Timtech follow the link Dennis is quoting

@0 ' so why doesn't my link work?

@DJMcMayhem the unofficial ppcg blog :P nothing too spectactular

11:33 PM

@ConorO'Brien () does nothing on its own. A second () also does nothing, and the {} pops a value but because there is nothing on the stack it behaves as a no-op.

What are you trying to do?

just trying to get a feel for the language

the docs say each evaluate to 1 tho?

> These are concatenated together when they are evaluated. So if we had a '3' on top of the active stack, this snippet:

()(){}

would evaluate to 1 + 1 + active.pop() which would evaluate to 5.

Yes

oh wait nvm

you need (...) to push

Yes. (), [], <...>, and [...] will not do anything on they are own

@ConorO'Brien They do. So the whole thing evaluates to 1 + 1 + pop() but then nothing is done with that value

11:36 PM

ok, cool. thanks :D
