Probably can be improved

@Mego Seems optimal to me

@EriktheOutgolfer That's Python 3.5+

Well for one, that's a different language

Mine was for any version of Python 3

Nope, that's not what that means. If a specific version is required, you have to denote that version.

Just realized it takes two clicks instead of one to get to the review queue now. Ugh.

@Mego Like Python?

Anonymous

@mbomb007 Python's syntax isn't exactly sane either, but it's the pleasant kind of insane, like a stranger singing in public. JS's syntax is the unpleasant kind of insane, like mental ward patients screaming at the top of their lungs.

HyperNeutrino

lol

that's a great comparison

6:45 PM

Haskell has the best syntax

John Dvorak

Ruby's like 'shrooms then. Most people don't understand it, but it feels awesome.

... I instantly regret making that comparison.

mbomb007

@Mego Yeah, I agree. I enjoy using Python. But JS is part of my job. If you do something wrong, the browser just stops execution. Troubleshooting can be hard.

Anonymous

@JohnDvorak I'd say Ruby's syntax is like the red pill from the Matrix: looks innocuous on the surface, but takes you down a rabbit hole that makes you question reality.

Mr. Xcoder

If there'd be a language with the built-ins and modules of Python, syntax of Haskell, features of Ruby and the performance of C, it'd be awesome

John Dvorak

@Mego Fair enough, I guess

mbomb007

Syntax of Haskell? Ew

@Mr.Xcoder I'm longing for Crystal on Windows

Crystal?

@Mr.Xcoder Haskell has really good performance for well-written code. It compiles to machine code.

mbomb007

@EriktheOutgolfer I'd rather see them all at once. Also, then I can open each non-empty queue in its own tab.

@JohnDvorak is glass a crystal? Most windows are made of glass.

Erik the Outgolfer

6:49 PM

wait why would you open review queues in separate tabs I'd say better reserve the tabs for golfing languages :p

FrownyFrog

glass is not a crystal

it’s almost the opposite

John Dvorak

Nope. Glass is amorphous.

mbomb007

@EriktheOutgolfer So that I don't have to go back to the main review queue page after reviewing a queue.

Glass is largely-unstructured melted-and-solidified silica. Crystals are highly-structured compounds. Glass is easy to make. Crystals are much harder.

Wait what

John Dvorak

Glass is easy to make. Just melt some sand.

FrownyFrog

just freeze some water

Mr. Xcoder

How is frozen water glass ಠ_ಠ ?

They look the same.

Mr. Xcoder

But they aren't

Glass is really easy to make. You just need 8 sand blocks, and 1 coal, throw them both into a furnace, and... oh wait

@FrownyFrog Anyone can make glass out of silica with sufficient heat. To make quartz, you need an autoclave with precisely-controlled temperature gradients. Or a volcano.

John Dvorak

Like I said, just melt some sand.

sure, an autoclave with a volcano is super-easy to find.

AdmBorkBork

I grew some crystals in a glass of water with a box off the shelf

Anonymous

Ice is a crystal too, but I meant silica crystals (aka quartz).

FrownyFrog

any crystal is easier to make than any glass

ok

HyperNeutrino

6:56 PM

@DJMcMayhem 1. you don't need that much sand, 2. you need stone, which requires at least a wooden pickaxe, which requires at least 3 logs (I think)

Erik the Outgolfer

@DJMcMayhem seems like you confused stuff up there :p

DJMcMayhem

@HyperNeutrino You do need that much sand if you don't want to waste coal

Let me revise though

Anonymous

@JohnDvorak It's one or the other. Volcanoes make natural quartz. Autoclaves make synthetic quartz.

HyperNeutrino

yes, but this is block-golf, save 7 blocks

DJMcMayhem

Okay, well in that case you could also use your wooden pickaxe as fuel

HyperNeutrino

6:58 PM

That's true...

DJMcMayhem

So you need 3 logs (1 for the crafting table, 1 for the sticks, and 1 for the three planks), then 8 cobblestone, and 1 sand. So 12 blocks minimum

Anonymous

Hmm, block-golf could be interesting. Find the minimum number of items needed to make an item in Minecraft.

That's an awesome idea actually

when it comes to minecraft I'm afraid I can't help

DJMcMayhem

Oh, it's 1

Of course, you could also put your two extra sticks in as fuel so you can keep your pickaxe

(Smelting power page for the interested)

HyperNeutrino

and the extra plank

and your crafting table

@HyperNeutrino 2. All you need is a piston and a redstone torch. Both can be found naturally.

HyperNeutrino

you can reduce this count using the Bonus Chest but that's cheating lol

@Mego how do you get into the end?

Anonymous

End portals have a 10% chance per block in the portal frame to already contain an eye of ender

Therefore you have a 10**(-12) chance of finding an already-constructed portal

empty = pristine with normal terrain generation, or void?

getting to mainland isn't an issue because sometimes you appear in the main island region

Also, no cheap answers like Use creative mode! or Console commands! Or Have another player drop one!

@JohnDvorak Normal terrain generation

lol

DJMcMayhem

I'm pretty sure that would be impossible in something like superflat lol

HyperNeutrino

you can get obsidian, redstone, and books from looting chests, so one block for the crafting table :3

DJMcMayhem

That's why I said no cheap answers

@DJMcMayhem :c it's legit tho

@DJMcMayhem 5 diamonds, 3 logs. Make a crafting table, then a diamond pickaxe. Find a village and smash a bookshelf for a book, and mine 4 pieces of obsidian from a cave.

HyperNeutrino

you need iron then

so you need stone

DJMcMayhem

But how are you going to mine the diamond?

HyperNeutrino

Anonymous

Fair

DJMcMayhem

And you'll need to smelt the iron too

John Dvorak

7:05 PM

CMC: make a mod that lets you mine diamond by hand

HyperNeutrino

:c

AdmBorkBork

Diamonds can be found in chests

DJMcMayhem

I'm guessing you'll need one coal, unless there's some workaround to re-use earlier leftovers

HyperNeutrino

@AdmBorkBork apparently that's "cheap" tho :c

Anonymous

So for the 5 diamonds, you need half a log and 3 iron for an iron pickaxe. For an iron pickaxe, you need half a log and 3 cobblestone for a stone pickaxe, plus 8 cobblestone and a piece of coal to smelt the iron. Stone pickaxe takes a wooden pickaxe, 2 sticks, and 3 cobblestone. Wooden pickaxe takes 3 planks and 2 sticks, which is 2 logs.

DJMcMayhem

7:08 PM

And one for the crafting table :P

@Mego IPS can boil down to "don't be a dick"

yesterday, by Mego

The answer to every IPS question is "have a mature conversation with the other person/people". The whole site can be closed as a dupe.

Excellent.

@Dennis The answer is still the same: "Unless it is clearly marked that the seat/parking spot is solely for use by you, get over it and find somewhere else to sit/park. In fact, go ahead and get over it even if it is marked."

Q: Repeat the Nth elements

We haven't had a string question for a while (5 days to be precise), so let's go for one. Given a string s and a positive integer n, take every nth element of s, repeat it n times, and put it back into s. For example, if n = 3 and s = "Hello, World!", every third character is Hl r!. You then re...
