@RadvylfPrograms well, I am actually using such an application right now to direct incoming traffic to one of two servers

they are on separate machines so I can't actually readily share the private key, especially since certbot creates a new one every month anyway

and the servers in question are using different software anyway so it's not like I can do anything about that either

Rust NPSP reimplementation is going well!

radvylf@penguin:~/npsp-rs/npsp$ cargo run
   Compiling npsp v0.1.0 (/home/radvylf/npsp-rs/npsp)
    Finished dev [unoptimized + debuginfo] target(s) in 2.48s
     Running `target/debug/npsp`
dca24fb6-5c0a-49fe-8f5d-108652c23d4e

It can grab an fkey, first step of logging in

And better than Node NPSP was doing

(And it also does it much more robustly, using proper HTML parsing instead of...yes, regex, I know)

I'd previously assumed they'd never update that page given that they haven't in like a decade, but apparently they do still make breaking changes on occasion and I could see them rearranging the order of the attributes in the input or something like that

Ginger

aw cmon, GB is ready to replace NPSP!

I only haven't done it bc I'm waiting for a week to check stability

mousetail

Make it a contest

Radvylf Programs

Well it would only ever be a temporary solution, it'd be a little confusing if our bot was called Ginger :p

mousetail

14:36

first bot to post each new post wins

Radvylf Programs

Plus NPSP-rs is going to have all sorts of cool features

And it's written in Rust using established libraries, so it should be more robust

PyGamer0

@mousetail good idea lol

mousetail

@Ginger host your bot as close as possible to SE servers

Grain Ghost

@cairdcoinheringaahing I honestly feel like it's harder to touch up old sandbox posts than it is to just make a new one.

caird coinheringaahing

@GrainGhost Agreed, but I don't think that's a reason not to do it

If anything, the same problem that we've had for the past 3 years is more relevant: can we do it for 25 challenges in 6 weeks?

Grain Ghost

14:47

I know I can write ~20 challenges in 6 weeks.

caird coinheringaahing

@GrainGhost Yeah, I'm thinking more about finding 25 challenge-worthy, abandoned Sandbox posts, leaving enough time to alert the OPs that we may be "commandeering" their proposal, and then touching them up

Radvylf Programs

Okay well I'm not actually IP banned by SE...

I wonder if it's the user agent being empty?

Grain Ghost

@cairdcoinheringaahing It's not unreasonable to have multiple advent events. I'd like to work on what we did last year since I know that works, and can be done.

You could try doing the other event. Even if it fails you either have it half done for next year or have experience for next year.

caird coinheringaahing

@GrainGhost I think we're both in agreement and talking slightly past each other :P

I've got no problem with both happening, you bringing up Advent of Golf just reminded me of my long-running and failed goal to do my Sandbox Advent thing :P

Grain Ghost

14:51

I'm saying where my priorities are. I will unlikely be participating directly in that sort of event this year. Although I absolutely endorse the idea.

Advent of code seems like a decent way for me to hit 100k before year end because my previous goal of getting a 3rd socratic this year is now definitely impossible.

Radvylf Programs

Okay phew it was the user agent

Its new user agent is Mozilla/5.0 (compatible; NPSP/2.0; +https://chat.stackexchange.com/rooms/240/the-nineteenth-byte)

That way if any SE devs decide to investigate the suspicious scary bot thing it'll direct them to us

caird coinheringaahing

Oh god, are we going to have to deal with angry devs asking why we have a chatbot that can post new posts in here before they're even posted on main? :P

@RadvylfPrograms it's called "GingerBot" q:

Using SEChat is how the last NPSP died

Ginger

wdym?

the last NPSP, iirc, used the horribly janky "library" made by hyper

sechat is of my own invention

caird coinheringaahing

Oh, I thought you meant the "standard" python library for SE chatbots

no, that thing is awful

I made sechat specifically because of how awful it was

@RadvylfPrograms good idea, just added user-agent code to sechat

it now has the agent Mozilla/5.0 (compatible; automated;) sechat/<version> (unauthenticated; +http://pypi.org/project/sechat) or

correction: the horribly janky "library" made by Radvylf

Node has no existing HTTP library which handles cookies

I didn't really have a choice

CMP: What makes a good answer-chaining question? (As opposed to simply a not bad one, or one which needs to be answer-chaining to work)

Ginger

the answers are chained together

Grain Ghost

1. Successive answers must be harder
2. It should be difficult or disincentivised to "lock the challenge" by making an answer that can't be followed.
3. Score should somewhat reflect the amount of effort put in.

Radvylf Programs

One where there is a high skill ceiling. You shouldn't be able to stasoid your way to a thousand answers, but it also shouldn't just become a brute-force sort of thing when too many answers exist

Grain Ghost

17:00

I feel that if successive answers increase in difficulty that problem naturally sorts itself out.

I guess it has to start pretty easy though.

thejonymyster

hm. i've got this answer chaining sandbox, and i have a feeling it runs into at least one of those issues maybe :-) in particular, there are points where you end up with a really low (good) score, and theres not really anything anyone can do but post an answer with a worse score. I feel like people wouldn't want to put in the effort for something destined to score badly.

DLosc

@RadvylfPrograms IDK, I'd say that if someone does stasoid their way to a thousand answers, more power to them, but it should be so difficult that almost no one would try it.

Radvylf Programs

Well I also mean that it should remain interesting as it gets harder, and not just get less possible

Why does this library not provide a way to initialize an empty cookie store

If it's text, ₈¡ṗ (powerset(256!)) is quite a bit longer.

DLosc

@DLosc Ooh, I think PMr will be longer: permutations of a random floating-point number. I tried it on DSO and it froze my web browser. :D

thejonymyster

18:38

lmao thats a good sign

oh wait is that string permutations?

DLosc

Yes

I think the length of the output of PM given a length-N argument is going to be N times N factorial, so PMr should typically generate somewhere between 17*17! and 20*20! characters

thejonymyster

wait is that 20(20!) or (20*20)!

sometimes i joke about order of operations but i genuinely dont know where factorial fits in :P

DLosc

I'm assuming it's higher precedence than multiplication

thejonymyster
