It's annoying how programs that store your password often don't allow you to look at it.

So instead of just looking at it, I have to make a fake server to get it.

Erik the Outgolfer

um... how is the password "stored"?

and is it a website?

feersum

In a config file somewhere, I presume.

In this case it's an email client.

I found a nice pop3 server Python script, so it went pretty smoothly.

Erik the Outgolfer

sounds like a total security fail to me...

feersum

Just had to disable a few security settings.

@EriktheOutgolfer How do you expect it to work?

Erik the Outgolfer

salted hash

feersum

09:26

The email client needs to know my email password so it can authenticate with the mail server.

Erik the Outgolfer

oh, so it's an actual downloaded program

in this case, I'd say that there's little to no harm storing the password locally

what would be concerning is storing the password in plaintext in the server

feersum

Speaking of logins... I tried to create a Twitter account a few days ago, and guess what? My account was auto-suspended for "suspicious behaviors" before I could even read one tweet.

The sad part is I only wanted to use it for reading only.

Erik the Outgolfer

sounds like somebody in your IP range has been naughty...?

feersum

Wasn't even using my VPN...

Erik the Outgolfer

I mean your real IP range

like, neighbors

feersum

09:36

Sure that's possible, I'm just saying, I did the most I could to avoid being a suspicious IP, lol.

Neil

10:31

you need a Twitter account to read tweets?

feersum

11:13

@Neil The point is to make it easier to follow people.

Nathan Merrill

@Veskah Here's to hoping Firefox doesn't follow

Adám

@NathanMerrill And maybe Chredge won't either. Google needs to show ads to make a profit. Microsoft doesn't. This would be an excellent opportunity to gain an edge (!) against Chrome's near-monopoly. In fact, Microsoft would implicitly be able to hurt Google by helping people to block their ads.

Nathan Merrill

Is that API part of Chrome or chromium?

because, I could see it difficult to add it back in if it is in Chromium

because it likely has lots of hooks that would be difficult to put on top of chromium

J. Sallé

@NathanMerrill Amen to that!

Veskah

Ha ha, sharing your screen with your boss when you have TNB and PP&CG tabs open

Adám

What should the new Edge browser be called?

@mınxomaτ I finally took the time to learn to use a deep learning library and tried to implement this.

It is really fun to play around with:)

A: Sandbox for Proposed Challenges

Finding distinct road sections I was recently working on a grid-based road procedural generator, and thought of a neat idea for a new challenge: The Task Given a square (equal width and height) 2d array in which each item is one of 2 distinct values (of your choice): grass and road (I will use...

Q: Incremental Ranges!

Your task is to, given two positive integers,x and n, return the first x numbers in the incremental ranges sequence. The incremental range sequence first generates a range from one to n inclusive. For example, if n was 3, it would generate the list [1,2,3]. It then repeatedly appends the last n...

@primo Cool answer for pi^1/pi. (you probably already know, but it fails for n=2175, which I don't like about the challenge)

NB. I don't suggest you try and fix it

primo

i was planning on adding a solution with faster convergence as a post-fix

ln(pi)/pi = lim (pi^n)/(2n agm(pi^n,4)) n -> infty

H.PWiz

agm?

gamma?

primo

arithmetic-geometric mean

@H.PWiz quadratic convergence. conveniently, pi can also be computed in terms of agm, if ln(2) is known: wolframalpha.com/input/…

ln(2) can aslo be computed with quadratic convergence, which would make e the bottle neck, despite being super-linear

H.PWiz

19:21

@primo I messed about with your solution for a while, but only managed to add 7 bytes. Might be interesting though: tio.run/##LY6xCgMhEET7@4qUuiKrlyYo@znCrYo5w4WQLfLrxiNphuHNK2Z/…

Make that 5 bytes: tio.run/##LY7BCsMgEETv@YoedUVW00tJ2M8RsipWi6V0D/11ayCXgXnzDlO//…

Probably less confusing if you move q* down from line 5 to line 6

primo

19:36

@H.PWiz i initially planned to use Lambert's formula for pi, but it was slightly longer: tio.run/…

produces 4/pi

Draw an Image on the screen efficiently code-golf Imagine you have a special rectangular screen made of square pixels. It consists of \$n\$ rows and \$m\$ columns. For every row and every column there is one swich (so \$n + m\$ switches in total). To turn a certain pixel on - let's say at posi...

Q: Here's your site design preview!

Three great discussions and 6-8 weeks later, I'm here to introduce you to your new site design! Thank you to everyone who contributed ideas to the discussion -- there were many great points of inspiration for our designer, Lisa. Special recognition to DJMcMayhem's suggestion of Conway's Game of L...

DJMcMayhem

WOOOOOOOO

Catija

I think I broke the Featured on Meta box again... Sorry. If it's not fixed in a couple of hours, I'll get someone to unbreak it. :/

Doorknob

@NewMetaPosts I'll be the first to point out that our header contains the substring "Owo" :P

flawr

I hope the background is animated:)

Catija

HAHA. I think we'd probably get throttled if it were... :P If that's a sincere hope, I'm sorry to crush it but it's static.

DJMcMayhem

20:16

@Catija It's OK, we're pretty used to the featured box being broken

flawr

Why is there a person with a tie that is too long hanging upside down in our new logo?

Skidsdev

@NewMetaPosts I'll be the first to say (at least in chat) the design is amazing, I love it.

AdmBorkBork

@flawr It's clearly a pen nib printing a period.

Skidsdev

Was just about to say I love the Medal/Exclaimation mark portmentaeu

Catija

Speaking of the featured box... I think we're going to be activating that info box we use on Christianity for the purpose of linking to your sandbox... can y'all think about what the best wording for it would be?

Poke

20:21

@Skidsdev mexcalamation mark?

Skidsdev

@Catija So a small, permanent "featured box" style notice to ask people to post challenges in the sandbox first?

@Poke Exclaimation Medal, of course

Poke

@Skidsdev oh i like that better :]

Catija

@Skidsdev Yep!

flawr

with the two vertical bars but a single period it is a sesqui-exclamation mark

Skidsdev

@flawr sesqui-exclamation medal*

Adám

20:23

If a interrogation mark and a bang share their period (‽) it is called an interrobang. Clearly, this is an exclamation mark and a bang sharing a period, so it is a exclamobang.

Skidsdev

@Adám but it's also a medal

Poke

or just a bangbang

DJMcMayhem

@Catija That would also be a great place to mention we don't do code troubleshooting

Poke

;)

DJMcMayhem

Or SO-style programming hlep

Catija

20:24

@DJMcMayhem If we're turning it on, y'all can think about what you want it to say... maybe start a meta about it? You're much better able to decide what to say there than I am.

flawr

@Catija I think the first paragraph of the sandbox post is quite good, something like:

> The Sandbox is a place where you can get feedback on prospective challenges befor you post them on the main page. This is very useful as writing clear and fully specified challenges on the first try is difficult. There is a much better chance of a your challenge being well received if you post it in the Sandbox first.

Adám

@DJMcMayhem Except help to shorten code.

AdmBorkBork

@Adám "Exclamobang" sounds like something I'd see in an Adam West Batman series.

Downgoat

@NewMetaPosts comment on the logo: it looks was influenced by the likes of this suggestion but it seemed to be pretty unpopular?

flawr

(maybe it can be golfed a little bit)

Skidsdev

20:26

@AdmBorkBork You mean Adám West? ;)

Adám

:-D

Skidsdev

or maybe Adm West

AdmBorkBork

That's obviously correct, because it's golfier.

Adám

Adm←

Poke

@Adám Adam Left? :P

Adám

20:28

@Poke Adm West

flawr

Adm Backspace

Poke

Well that's totally pointing north for me right now ;[

Adám

@flawr That's just "Ad"

flawr

hehe

Adám

@Poke Wait, is your screen flat on the table?

flawr

20:30

sometimes i thought it would be a fun idea to have an ASCII character that deltes the previous ones

DJMcMayhem

You mean ^H? :P

Adám

@flawr That's ASCII 8

Poke

@Adám IT COULD BE (but no... it's not)

Adám

@Poke Then you're facing east.

flawr

@DJMcMayhem yes but thats not a character that you can type, that is an instruction, isn't it?

Poke

20:36

@Adám As one does

DJMcMayhem

@flawr You can type it in a terminal

ctrl-h

flawr

but can you delete this charcter and get the original one back?

DJMcMayhem

Ah, no not really

Adám

@flawr Yes you can.

Poke

@Catija something something css animation with keyframes on a loop?

flawr

20:41

Something something jquery interactive something turing complete something something tetris

Poke

you wouldn't even need jquery :]

or javascript

flawr

well you'd need a ton of frames to make an accurate GOL

I think they want to prevent people from abusing GOL for mining bitcoin, because of all communities on the internet PPCG is probably the first one to try that.

Poke

@flawr mmm yeah probably

J. Sallé

@flawr Challenge idea: Golf a bitcoin miner in GOL.

Downgoat

is it just me or does the site title in the design look a bit elongated due to the smaller padding

flawr

20:46

@Poke did you realize you wrote message number 50499999?

Downgoat

@flawr userscript idea: simulated GoL in PPCG background

Poke

@flawr That's not something I check very often :P

so no

Adám

@Poke If the world only has oscillators, it is doable.

@Downgoat Why not real CSS GoL hand-cranked by all user clicks on the page?

Downgoat

@Adám would require an absurd amount of DOM nodes but maybe not impossible

J. Sallé

Who needs performance or usability when we can have a running GOL background?

Peter Taylor

21:25

I'm disappointed that after all the effort I went to make some vaguely imaginative suggestions we've ended up with vanilla GoL.

ngn

@flawr hm, am i the only one who sees the upside-down logo as something inappropriate to mention here

flawr

@ngn oh god

hahahaha

flawr

21:51

I suggest an improvement

user image

Nathan Merrill

22:24

@PeterTaylor I think there were two outcomes here: (1) Designer reads vague instructions, builds run-of-the-mill GoL. (2) Designer reads vague instructions, doesn't know anything about GoL, but runs with it and builds something that isn't like GoL at all.

You'd need somebody that is both a designer, and it intimately familiar with our world to really get something unique.

MilkyWay90

@Skidsdev aw man

@NathanMerrill lol

Anonymous

@PeterTaylor Our highest-scoring (and most well-known) challenge is about GoL, so imo it's thematically appropriate

noɥʇʎԀʎzɐɹƆ

23:52

is anyone interested in a tool like this (except the line erases itself every time)?
