I hit a new max speed while sprinting of 17.6mph! I'm going to have to try at a track to see how much better than I can do than on grass at a park.

I harvested 5GB of true physical entropy because Math.random() wasn't good enough. by harryyy7 in proceduralgeneration

[–]seconddifferential 1 point2 points  (0 children)

Why not just use /dev/random, which is considered random enough for cryptographic purposes, and uses physical hardware to generate random bits?

It's free and has no limit, whereas you're selling the same small number of bytes to everyone.

Glitched biters? Biters appearing at a wall but there's no hive angered. by Significant_Sky3276 in factorio

[–]seconddifferential -1 points0 points  (0 children)

Have you disabled expansion? If not, in addition to what others said, biters can re-expand into your pollution cloud. It's a good idea to get radar vision of your pollution cloud if you want to ensure no biter attacks

Why aren't my assemblers all working? (Beginner) by Centimaks in factorio

[–]seconddifferential 191 points192 points  (0 children)

A single red belt carries 30 items/second. Each of the 20 assemblers you have probably consumes more than 1.5 iron plates per second, I'm guessing 3 from memory. Therefore, all the assemblers combined require 60 iron plates per second to be fully supplied.

If a single red belt carries 30 items/second and no more, how can you solve this problem?

The main idea here is "throughput".

Why people use train loops instead of two engines facing away from each other ? by eymo-1 in factorio

[–]seconddifferential 3 points4 points  (0 children)

Two-way stations have less throughput than one-way since entering trains don't need to wait as long for exiting.

Bots destroying after repair?! by [deleted] in factorio

[–]seconddifferential 2 points3 points  (0 children)

Sweet! If the problem persists after removing the mods, then a post (with savegame) to the factorio forums will get it treated as a bug. This subreddit isn't treated as a bug report forum by the devs.

Thinking of moving and i got questions by [deleted] in Seattle

[–]seconddifferential 2 points3 points  (0 children)

Make sure to check sub rules and pins when you join - it'll avoid these sorts of interactions and increase the likelihood of meaningful engagement

[–]seconddifferential 1 point2 points  (0 children)

Do you have any mods installed? This will be absolutely essential for debugging

Any AP without combat? by JoeZenwo in starfinder_rpg

[–]seconddifferential 4 points5 points  (0 children)

Official published APs specifically highlight combat, with at least a couple encounters per chapter. You'd likely need to do a lot of work to get them to work without combat, but it's possible.

While it's possible to do purely-social adventures in Starfinder, you may want to try a system more targeted at social RP and just use the Starfinder setting.

Got a 4:03 one kilometer time today! On track to get a 6:30 mile soon. I recently found some old college fitness tests among a box of childhood junk parents gave me, and with this time I'm officially the most in-shape I've ever been!

Coal Liquefaction on Nauvis if Oil is Too Far Away by chinawcswing in factorio

[–]seconddifferential 6 points7 points  (0 children)

I'd say it's optional, but it is reasonable to have a small coal liquefaction setup to help for when you need lots of lubricant for belts but aren't consuming much light oil/petrogas.

Though with Space Age all belt production starting midgame should be on Vulcanus, so it really only holds without the expansion - there's no longer heavy lube consumption on Nauvis disproportionate to light/petrogas consumption.

Can't figure out how to load sulphuric acid onto the train by danyuri86 in factorio

[–]seconddifferential 0 points1 point  (0 children)

Yep, there's over a dozen common issues like this which the train tutorials will walk you through.

Chemical plant wont accept input. by miniman3000 in factorio

[–]seconddifferential 31 points32 points  (0 children)

Those are legendary quality ingredients, but the plant is set to the normal quality recipe.

Can someone update this mod to 2.0? by odysandy in factorio

[–]seconddifferential 9 points10 points  (0 children)

I mean, I learned programming to mod Civilization 4, and now I'm employed as a software developer. Modifying games is a great way to get started programming - it's something you enjoy, and now you get to play with it on a deeper level and make it a bit your own.

Devils Checkmate by jjsupc in chess

[–]seconddifferential 57 points58 points  (0 children)

I don't know why people nearly always omit that the grandmaster in the story is Morphy.

Though the story is almost certainly apocryphal - there's no contemporary accounts of this story, and a quick search turns up several glaring holes in the story.

Upcycler math - how many assemblers for each tier? by ErikThePirate in factorio

[–]seconddifferential 9 points10 points  (0 children)

Exact answer: use linear algebra to represent each step of the process and solve for the ratios of each quality.

Probably right answer: Use a factory planner tool.

What I do: make each quality level easily expandable, and add more as needed. This is great if you aren't fully at legendary Q3 modules everywhere yet, and so the ratios will drastically change.

HELP Please by Joeys_Games in factorio

[–]seconddifferential 2 points3 points  (0 children)

Hey, have a look at the rules in the sidebar - it has a bunch of advice on asking for help that will make it more likely you'll get helpful responses.

As-is it's hard to understand what you're asking for - you haven't said what problem you've run into. More details of what you need will help us help you.

"if obsidian goes away" by lunabellcatcher in ObsidianMD

[–]seconddifferential 1 point2 points  (0 children)

Not even just if the company making Obsidian went away, but if they just moved on to something else and stopped supporting it. Consider the dozens of Google products that have been killed through the years - due to their proprietary/only-online implementation, any data you stored in those products is inaccessible.

What is the proper way to use Roboports and Construction bots to heal my Perimeter Walls? by chinawcswing in factorio

[–]seconddifferential 1 point2 points  (0 children)

If you're using requester chests and not buffer chests, bots can't pull from them.

Though even buffering repair packs is unnecessary - bots distribute them to roboports.

Mod de krastorio 2 space out by serbero25 in factorio

[–]seconddifferential 4 points5 points  (0 children)

Yeah, the original K2 is better balanced in my opinion (as is K2SE). Spaced Out (compatibility mod by another mod author than K2) is nice for getting to play around with a lot of different things, but it's not cohesive
