A: Sandbox for Proposed Challenges

[KotH] Play a game of Nose Poker Nose Poker is an ogre game played by a group of ogres. Each ogre brings a large nose and a small club. On each hand, all the ogres will declare how many times they will poke their nose with the club. Each time, the lowest bid(s) will be knocked out of the game, th...

Completely unrelated, but just a friendly reminder that this was once my profile picture

@math Fair point. I can't really think of a way to test out the importer without one, tho I know they're annoyng.

@Neil you are a genius :)

I also didn't know you could actually use 128 bit constants

that was a 64-bit constant, and I don't think 128-bit constants exist

12:33 PM

@thedefault. right. It's very odd that this is still the case in 2021

128-bit integers are not standard

128 bit ints are not very commonly used, to be fair

oh yeah, they're also not standarised in C

Right but normally gcc takes the lead

I would have thought gcc would have extensions for uint128_t

And then C can catch up in 2050 :)

@lyxal Did you ever have an amogus pfp?

@lyxal String.valueOf(new Integer((int) Integer.valueOf(10))) :p

@pxeger I applied to Kings College and 4 others. 3 of the others got back to me in days, with unconditional offers. One took a couple of weeks. You can't accept an unconditional offer until all 5 get back to you. The deadline for accepting was June 1st. By May 29th, King's still hadn't got back to me, and I had already decided to accept Bristol's offer, so I retracted my application to Kings

oh that's a lot more complicated than I expected

caird coinheringaahing

Yeah :P

Warwick took a few weeks to get back to me, just to reject me because I haven't taken the Step exam :P

@AJFaraday Can you not reuse them?

why didn't you check that before applying lol

caird coinheringaahing

@pxeger I did, but I figured because I was applying late, they might give me a conditional on sitting the exam :P

12:58 PM

oh ok

the whole system is so complicated for anyone other than a 6th former doing A-levels applying for the next year, following the exact "normal" path lol

laughs in got into uni based on my marks from the year before graduation

because we do that here

@lyxal that's what "normal" students in the UK sort of do too

you get conditional offers based on your "predicted" grades (and other requirements like interviews or whatever), and then you accept 2 of those offers, and if you meet the conditions (which are typically "get these grades", then you get in to that uni)

@pxeger lol mine was unconditional.

Heck, I got the offer about a week or so after my final exam

No wait, it was the very next day

oh yeah, you can also get unconditional offers or sometimes offers like EEE (terrible grades, but on the assumption you will definitely do better than that so it's effectively unconditional)

caird coinheringaahing

@pxeger EE, also known as "the royal grade" :/

1:13 PM

lmao

user image

this looks so unbelievably wrong

(aside: I just spelt "unbelievably" right the first time; this is unbelievable)

@pxeger That do be how StackExchange works

@cairdcoinheringaahing EE?

Error Error?

Extra Error?

Searching for EE grade on DDG returns stuff about pencils and other stuff

I think caird said it because the royal family are so stupid they only get 2 E's (most people do 3 subjects) but then still get in to unis because they're the royals?

I still don't know what E is

Is it the least poggers grade?

caird coinheringaahing

Yeah, Charles' offer to Oxbridge was two E's (the lowest passing grade)

@cairdcoinheringaahing Usually, yes. Although on this occasion there was an answer from someone else (I'd asked them to try out the mechanism), and so I couldn't clear that out to do my testing.

1:32 PM

@lyxal well there's also U, which means you missed the exam or you drew a massive cock and balls on the front of the paper or something which means they didn't bother marking it

caird coinheringaahing

The 2021 Community-a-thon has begun

Essentially a 4 week event where staff members at SE are encouraged to "go out into the wild" and engage with other sites on the network

"Improve Empathy" is a somewhat clinical way of putting it

Is it?

Hmmm.

2:00 PM

Can we considerably improve the empathy between the two parties by having @Catija make a cake for us? And we'll give stroopwafels ;) — Ollie 7 mins ago

Never eaten a stroopwafel, but I think SE's popularity would rise considerably if they made us all cakes and stroopwafels :P

2:15 PM

Stroopwafels are amazing.

Do they taste pretty much like ordinary waffles? They look pretty similar

They're like waffle cones with a very light caramel syrup.

And they're best served while warm and still a bit soft.

Here's a video that shows how they're made:

Stroopwafel recipe - How to make stroopwafels

caird coinheringaahing

@cairdcoinheringaahing Interesting that this seems to be a somewhat contentious issue

2:31 PM

Those look really nice, I need to try them sometime

The stroopwafels, not the HTML changes, I mean

Not sure where you are, but there are companies selling them in groceries in the US, so you can get some rather than having to make them from scratch - I've not tried making them myself but my dad has a pizelle iron so I may see if I can borrow it sometime.

@cairdcoinheringaahing I think some people think that userscripts shouldn't be SE's first priority because they're third party hacks, maybe

We're not even asking for it to be a top priority though, just that when they change something just say "hey we changed this" and if anyone needs to they can just fix whatever they must.

I think rene's answer on the linked question makes a lot of sense - Not sure if you've read it. He's in a similar position but he also knows that asking us to give a heads-up can be really hard.

(link for quicker access)

2:35 PM

Thanks :D

caird coinheringaahing

Ideally there'd be some way of just posting like an unparented "comment" saying "Hey y'all, we just changed X to Y, check if that breaks anything", where its not even a full post, just something to let those in the know know

His answer makes sense, but would it be possible to deprecate or warn users about certain parts of the API before removing/modifying them?

I don't think we mess with the API very often?

And even when we did recently, the older version still worked - but... I'm not a dev so I may be missing something obvious.

Sorry, probably misused the word API, I meant the UI and other stuff people mess with

I don't think SE should really care about what unofficial extensions they might affect when making the changes, but it would save digging through source code and debugging if we just knew "oh yeah they added IDs to the headers so shit's broken". Of course, some scripts won't be mantained anymore like rene mentioned and there's nothing wrong with that.

Granted, I don't know how often SE changes components, but would it be totally infeasible to have some changelog posted somewhere so whenever a change happens it just mentions which part changed and what? Like, for this change, it could literally just be one sentence saying "The HTML in headers within posts now contains an ID", and that's enough for us to figure out what went wrong with OSP.

2:38 PM

We use GH, but I'm not sure they have a way to make a publicly-viewable changelog that just shows the comments or something like that.

caird coinheringaahing

Having a "recent updates" Q/A that's edited when changes are made might work

Perhaps a separate repository used only for a public changelog?

Or an RSS feed?

... I mean, it all goes back to rene's main point - anything extra that's added reduces the amount of work that devs can do because they're having to remember to create these public artifacts.

caird coinheringaahing

Isn't there already a MSE post for the changes/additions by month for each year?

Yep. But they're usually much larger changes.

2:41 PM

I have a rather silly idea.

We can create a bot to scrape one of each type of available SE webpage like once a day or so and if any changes are detected it can run a diff on the files and then one of us can figure out what the change is an update a post somewhere.

I can understand devs having better things to do with their time - a lot of us clearly have too much of that anyway though ;)

caird coinheringaahing

@hyper-neutrino But what if SE changes something that breaks the bot? :p

The problem with that is that it might notify you even when there's no cause for alarm

True (like if someone edits the post we are scraping lol)

(Which isn't necessarily a terrible thing)

but that's why someone would go through and find the exact change to update it, or if there's no change, ignore it

2:47 PM

If it's not difficult to build, you could certainly try and then see how noisy it is and try to optimize.

If it was beneficial, it might be something others would help improve - like Charcoal or SOBotics.

If there is interest in that I can create a meta post with every single markdown/HTML feature in it and lock it for a reference point ¯\_(ツ)_/¯ I think this could possibly work

Page content itself changes all the time though so I'll probably want to get an HTML parser and try to see when the structure itself changes

~~time to use some regex~~

RIP HN

What's wrong with HN?

caird coinheringaahing

Parsing HTML with regex :P

I think it was a joke about using regex to parse HTML.

(To be clear, "HN" usually refers to me here, not Hacker News, just in case that was confusing.)

2:58 PM

HAHAHAHAHA

I went to look and see if something was wrong with the site.

caird coinheringaahing

@hyper-neutrino Clearly you are Hacker News, conspiracy solved :P

:o

caird coinheringaahing

Ugh, I keep getting ads on YT for unis :/

I miss the days when ads were so bad at tracking user data that they'd be completely random

have you heard about the Target targeted ads (lol) that managed to figure out that a teen girl was pregnant before her father even did?

(Forbes article)

yes

Redwolf Programs

3:09 PM

All of the YT ads I get are completely random and unrelated to my interests lol

@cairdcoinheringaahing ublock origin + sponsorblock = barely even know what an ad is

@RedwolfPrograms ^

Redwolf Programs

The most recent example I remember was an ad for birth control for cows

uh. what

caird coinheringaahing

@pxeger But then how will you know that this chat message was sponsored by NordVPN?

@cairdcoinheringaahing You won't, just like how websites you visit won't know if you're secretly a gay pirate assassin

6

caird coinheringaahing

3:12 PM

Yes, that totally does not describe me in any way 👀

lmfao

caird coinheringaahing

@hyper-neutrino If you're a pirate assassin who's in the closest, are you "secretly a gay pirate assassin"?

Redwolf Programs

Well are you secretly a pirate assassin? No, that's obvious. You don't want that ambiguity, so "a pirate assassin who is secretly gay" is better :p

Maybe you've come out as gay but you haven't realized/haven't told people you're a pirate assassin :P

No, that would be "if you're a secretly gay pirate assassin" which could also mean "an assassin who is secretly a gay pirate" (although that is not really accurate because "pirate" is not an adjective)

3:15 PM

secretly-{gay} pirate assassin or secretly-{gay pirate} assassin

It's used as a modifier here, right?

(English people please correct me)

Redwolf Programs

You could replace it with "pirating", but then it could seem you're an assassin who secretly pirates gay people

The only reasonable interpretation is "you are a gay pirate assassin, the entire identity of which is secretive", because it is in the form <subject verb adverb noun> which means the subject (you) is verb-ing (being) the noun (a gay pirate assassin) adverb-ly (secretly)

@pxeger ah, nvm, that does work then

Redwolf Programs

@RedwolfPrograms ...is a sentence which I never thought I'd say lol

caird coinheringaahing

@RedwolfPrograms How do you pirate a gay person?

3:17 PM

YOU WOULDN'T DOWNLOAD A GAY PERSON

@cairdcoinheringaahing Afraid? :P

Redwolf Programs

By attacking their naval vessels and stealing their treasure, of course

caird coinheringaahing

@user Slightly :P

@RedwolfPrograms Hey, we earned that treasure!

@cairdcoinheringaahing Perhaps they meant videos of gay people?

Redwolf Programs

Probably not

@pxeger I can good words :P

@RedwolfPrograms Unlikely, there's already 2 featured things on MM

Oh, up to an hour this time? Unless I'm remembering incorrectly, it's usually 15m right?

caird coinheringaahing

I think it's normally up to an hour (last time for example)), but they say it's likely to take ~15m

4:09 PM

ah okay

caird coinheringaahing

The time is weird tho, they normally happen at 1am UTC IIRC

4:23 PM

It's a Saturday, so the time is different.

@user it is, that's an anatomically accurate portrait of yo momma

@hyper-neutrino ...what happened there?

@pxeger bruh

@pxeger Here's an anatomically accurate portrait of yo momma (WARNING: creepy crawly)

5:34 PM

@Catija they gave me tooth decay though :-(

I just had a root canal last week. I know all about that.

anyone understand Makefiles ? How can I get it to report if the version of gcc is too low?

5:56 PM

A: Checking the gcc version in a Makefile?

I wouldn't say its easy, but you can use the shell function of GNU make to execute a shell command like gcc --version and then use the ifeq conditional expression to check the version number and set your CFLAGS variable appropriately. Here's a quick example makefile: CC = gcc GCCVERSION = $(she...

Not the same question, but you can basically use that answer and modify it to error or something depending on the gcc version, I think

@user thanks! Do you know how to get Makefile to print a message of your choosing?

I assume echo should do the job?

do you have to call that via "shell echo" or something like that?

idk, I've never made a Makefile myself, just guessing here

Redwolf Programs

printf is obviously better than echo, because it has 100% fewer es :p

6:06 PM

I'd recommend asking on SO, honestly

@RedwolfPrograms Obviously, puts is best because it's smol

Or cat, except cats are evil

Redwolf Programs

Wait does bash have that?

Also does cat print anything? I thought the whole point was its output was on STDOUT

idk, I am a complete noob when it comes to Linux :P

You're right, you'd need to do echo "foo" | cat or smth, which defeats the purpose of using cat

Redwolf Programs

TIL you can skip a skippable YT ad even during the 5s countdown; the button will always work, even when it's hidden with CSS.

You need a script to do it though.

wh-

i mean i guess that makes sense, but i would've expected the button to just not exist or be disabled

Maybe that's how YT adblockers do it?

Redwolf Programs

6:21 PM

@Adám No, because the unskippable ones don't have the button at all

@RedwolfPrograms Cool, do you know where to find such a script?

Redwolf Programs

I can give you mine

That'd be great, thanks

Redwolf Programs

Link (I gave up halfway through deciding on a name)

It also does a few other ad-related things

lol

Redwolf Programs

6:29 PM

You can press x on your keyboard to skip any skippable ad at any time, or dismiss any banner ad

~~Doesn't look too sus~~ Actually, it's JS

@RedwolfPrograms Cool

Redwolf Programs

It also makes banner ads with images 1/4 opacity, and makes clicking on them dismiss them instead of opening the ad page

caird coinheringaahing

@RedwolfPrograms I just use the (i) button and report the ads

Redwolf Programs

I guess that's one option lol

@cairdcoinheringaahing Do they let you skip them then?

Huh, nice

Guys, check out my new website! I discovered a hack that lets you host your own website for free 😱, without buying an expensive domain or getting servers. Very proud of this

CMQ: Why can't I set multiple passwords so if I make a typo that I often make when typing it, that's also accepted?

Why not just set the typo as your password then?

@RedwolfPrograms why the hell wouldn't you just use a god damn ad blocker?

Redwolf Programs

6:57 PM

Because I still want to support the people whose content I'm watching?

Redwolf uses JS, do you really want to question their logic?

@user because I still mostly type the one without typos, and at the very least I'm always aiming for the right password

Redwolf Programs

@pxeger Increased server load is one reason I'm sure

Hashing is, by design, a very slow operation

Guess you just need your own OS then

@RedwolfPrograms Is it?

Redwolf Programs

Password hashes like argon2 are quite slow

6:58 PM

yes because if it weren't you could brute force it

That's cause it's inert

Redwolf Programs

I've DOSed myself by using some default settings that were way too strong

@user If my password is supposed to be password, then I set it to pqssword because of typos, then I'll aim to type pqssword and end up typing p1ssword or whatever

one thing cryptographically secure hashes prioritize is being algorithmically slow and having no way to optimize it

Redwolf Programs

Plus giving people the option to set multiple passwords makes them more prone to use weaker "backup" passwords or repeat the same few across multiple sites, and adds server load and storage space and nonstandard security practices to worry about, for almost no gain

Although I hear facebook tries a few variations of incorrect passwords, like with case inverted

7:00 PM

@RedwolfPrograms "slow enough not to be brute-forceable" and "very slow" are different

Redwolf Programs

Well very slow when you have a large number of users :p

@RedwolfPrograms so clearly the increased server load isn't too much of a deal breaker for them

Redwolf Programs

Yeah, so that's probably not the main reason

@hyper-neutrino Why?

Redwolf Programs

I think there's just not really any reason companies would want a system like that; it's simpler to just do what everyone else does

7:02 PM

@user Are you talking about them having consistent timings for all kinds of passwords so you can't tell what's happening based on the time it takes, or is there something more?

@RedwolfPrograms well let's say you allow users to set 3 passwords. Server load includes quite a lot that is not hashing passwords, and even when it is hashing passwords it doesn't take massively long compared to the whole rest of a request's processing (making database queries and waiting for the network for example), so server load isn't tripled

Because aiming to be slow sounds like a bad idea

Redwolf Programs

@user You don't want them to be able to be done quickly

well it shouldn't be that slow that it takes like 4 seconds

Redwolf Programs

@RedwolfPrograms Because it makes brute forcing more feasible

7:03 PM

but if it's too fast it's ^

Oh

Redwolf Programs

@pxeger Yeah, you're probably right that that's not the main reason

Perhaps it's just less secure, then?

Redwolf Programs

It is, yeah, and for no real gain from the site's perspective

People are 100% going to abuse a system like that, and compromise their own security

but I could at least set this on my desktop screen locker, which (a) has 0 server load because only I ever use it and I can only type passwords one at a time; and (b) already makes me wait 200ms between password attempts to prevent brute-force

7:04 PM

You should do what I do and set all your passwords to qwertyuiop so they're easy to type

3

@pxeger How easy is it to make one, though?

@user vbrb going to login with user and qwertyuiop so they're easy to type

Redwolf Programs

@user You joe, but in school I'd see at least one person per day sign in to something by dragging their fingers across the keyboard

> You joe

@pxeger No, it's just qwertyuiop

Redwolf Programs

Knew it!

7:06 PM

@user well I could just write a custom PAM module, which wouldn't be entirely infeasible
