Kathrynn: /* Memory cells */

== Memory cells ==

I am aiming to update the "memory cells" section.
* The "advanced cell" does not handle 1-tick bursts properly. (I updated the article and wrote about that)
* There should be more versions of the memory cell, including versions that can handle negative input.

I may post some of my designs here once I finish polishing them.

:Thank you for this, designs are appreciated here. It's good that you remain objective about their advantages and disadvantages. -- [[User:Bilka|Bilka]] ([[User talk:Bilka|talk]]) - Admin 11:57, 13 May 2018 (UTC)

:: Thank you for your incredible work on the Wiki. I am always 100% objective. In this particular scenario, the initial design is objectively flawed. Try connecting a simple clock (self-connected arithmetic combinator with + 1) into it and then disconnecting it suddenly, its memory will flicker between the last two values. More generally, if the current input is only given for 1 tick, then it flickers between the current and the previous input. I do not want to remove it without the approval of the original poster. Here is a demo of the flicker. This device on the left sends a 1-tick pulse of 1. The lamp turns on if the output signal is 1. -- [[User:SafwatHalaby|SafwatHalaby]] ([[User talk:SafwatHalaby|talk]]) 13:46, 13 May 2018 (UTC)

:: (edit: fixed link): https://streamable.com/5r7w8

::: Because your memory cell has the same size, the other memory cell has no advantages over it. So, I am okay with a removal of the "positive cell". -- [[User:Bilka|Bilka]] ([[User talk:Bilka|talk]]) - Admin 14:53, 13 May 2018 (UTC)

:::: Ok. Let's wait for a while in case the original poster has comments that we've missed.

:::: There's one advantage for the previous design: It's useful for someone that absolutely requires a reset-on-negative and not reset on a dedicated line, and does not care about the flicker issue. But that seems like a very rare edge case, and someone who needs it is most likely very experienced and doesn't need this guide. -- [[User:SafwatHalaby|SafwatHalaby]] ([[User talk:SafwatHalaby|talk]]) 15:54, 13 May 2018 (UTC)

There is a mistake in the new image for the "Positives and Negatives cell" by "Zippy." In the original image there is a green wire connecting the input of [2] to the input of [3] which must be present for the memory cell to function properly; without it the [M] output simply increments on each tick. In case that description is confusing, here is an image where I use the blueprint selection box to highlight the wire I'm talking about: https://i.imgur.com/XRLAEkh.png [[User:Maoman|Maoman]] ([[User talk:Maoman|talk]]) 11:07, 12 February 2021 (UTC)

The image for the decider combinator shows 1 greater than 30. It should be less than in order to work, and to match the text. -- [[User:Kathrynn|Kathrynn]] ([[User talk:Kathrynn|talk]]) 18:06, 13 February 2021 (UTC)

== Binary gates redundant? ==

The binary gates do not seem to have much function, because As of 0.16, arithmetic combinators have built-in binary logic support. -- [[User:SafwatHalaby|SafwatHalaby]] ([[User talk:SafwatHalaby|talk]]) 09:56, 13 May 2018 (UTC)

:I am not very experienced in combinators, but aren't the combinators OR, XOR and AND option bitwise instead of binary? [[User:My3DS]] changed the page to specify that just yesterday, so it seems important to me. -- [[User:Bilka|Bilka]] ([[User talk:Bilka|talk]]) - Admin 11:57, 13 May 2018 (UTC)

:: I am not sure I understand the difference between "bitwise" and "binary" in the context of 1-bit inputs.

:: The built-in OR, XOR, and AND produce exactly the same truth tables as the ones currently in the article for inputs of 1's and zeros, and are additionally capable of performing more than that for inputs greater than 1.

:: -- [[User:SafwatHalaby|SafwatHalaby]] ([[User talk:SafwatHalaby|talk]]) 13:25, 13 May 2018 (UTC)

::: Like I said, combinators aren't my strong suit :) So yes, they are redundant, but I'd personally wait and see what My3DS wants to do with the gates before removing them. Perhaps give them a week, and if nothing is changed until then, remove them. -- [[User:Bilka|Bilka]] ([[User talk:Bilka|talk]]) - Admin 14:53, 13 May 2018 (UTC)

:::: Ok :), does the wiki have some sort of "pinging" system to let them see the conversation?. -- [[User:SafwatHalaby|SafwatHalaby]] ([[User talk:SafwatHalaby|talk]]) 15:54, 13 May 2018 (UTC)

::::: You can't ping people directly, but if you leave a message on someones talk page, they will see a notification until they check it. -- [[User:Bilka|Bilka]] ([[User talk:Bilka|talk]]) - Admin 18:12, 13 May 2018 (UTC)

:::::: Thank you :) -- [[User:SafwatHalaby|SafwatHalaby]] ([[User talk:SafwatHalaby|talk]]) 14:06, 14 May 2018 (UTC)

::: I can see the merit in these designs for 3 or more inputs. But I think it should be clear to the reader that the 2-input designs are alternatives to the built-in ones, and that the bitwise vs binary sentence should be clarified. -- [[User:SafwatHalaby|SafwatHalaby]] ([[User talk:SafwatHalaby|talk]]) 14:06, 14 May 2018 (UTC)

I have updated the page to have some clarification of what is meant by bitwise and some additional notes on the gates, as some can function with boolean or non-boolean values (or binary vs non-binary values), and some can have more inputs. Let me know if something doesn't make sense or should be improved. I'm also not sure if the built in ones should be under the others or before it.

== This is not a beginner tutorial at the moment ==

This page seems inappropriate for circuit beginners and I've added a sentence at the beginning to keep beginners from getting frustrated; the circuit network page and cookbook page should be more helpful for beginners. A beginner section on this (or on a different page) that explains how to connect wires, how signals work and so on would be useful.

There's also a decent overlap with the cookbook page (the madzuri setup, memory cells, sr latches, logic gates). And virtual signals are explained here and on the circuit network page. That is not a problem as such but it means there is more work to keep it updated. In sections where the intended depth of explanation is comparable between the pages, it may be better to keep the content on one page and have a link on the other one.

== Working on improving the Virtual Signal section ==

So far I've rewritten the section explaining wildcards, as it was very terse compared to overview at the [[Circuit network#Logic signals]] section. Given that this is a tutorial page, they should be explained in depth, which I attempted to do.

I plan to add a similar explanation for the other virtual signals, but for now I've stayed up way past my bed time :) --[[User:ZeroKnight|ZeroKnight]] ([[User talk:ZeroKnight|talk]]) 10:41, 4 October 2019 (UTC)

Kathrynn:

This page requires a lot of updating to get to version 0.9.8 standards. I'm going through the individual techs, if someone could help with updating the images & the tech tree (tree diagram) that would be an immense help. I'm not too sure about how the formatting for that works yet.

A good tech tree for reference: http://davemcw.com/factorio/tech-tree/
Seems almost perfect, only a few techs missing like iron working and the latest follower robot techs at first glance. And it can be a bit hard to follow all the lines exactly. [[User:Teurlinx|Teurlinx]] ([[User talk:Teurlinx|talk]]) 18:21, 23 May 2014 (CEST)

And a proposal for the various technologies which have the same name as the effect - e.g. Speed module 1 & speed module 1 (research) - I suggest we merge the research page with the page for the item. I don't see a good reason to have the current confusing setup where they are separate. [[User:Teurlinx|Teurlinx]] ([[User talk:Teurlinx|talk]]) 20:41, 23 May 2014 (CEST)

: with the wiki generator I'm currently writing, this should be an easier task. I recommend to put not too much work into it. See https://github.com/alexaulbach/FactorioLua2WikiGenerator ... [[User:Ssilk|Ssilk]] ([[User talk:Ssilk|talk]]) 09:11, 27 May 2014 (CEST)
:: Don't worry about working on the individual pages, I've got that covered. If you could automate the creation of the tech tree and list of technologies, that'd be a better use of your time. [[User:WiduX|WiduX]] ([[User talk:WiduX|talk]]) 17:56, 27 May 2014 (CEST)

----

The research formula takes into account the modules when calculating S, but it doesn't include it when calculating for P. How could this be formatted? I don't want to make it more confusing... [[User:Kathrynn|Kathrynn]] ([[User talk:Kathrynn|talk]]) 16:26, 27 Nov 2019 (UTC)
