'''Billon''' is an alloy of equal parts [[silver]] and [[copper]]. Historically, this was used to mint coins, but without modding the game's object files, billon coins will have no function in the [[dwarven economy]].

Two billon bars can be made at a [[smelter]] from 1 chunk of silver [[ore]] and 1 of copper ore, or 1 silver [[bar]] and 1 copper bar. Two units of [[tetrahedrite]] count as 1 copper and 1 silver ore, and will yield two bars of billon. This last recipe will only be used when no other silver ores like silver or [[galena]] are available to the [[smelter]], otherwise silver nuggets or galena ore will be preferred, the tetrahedrite then acting as copper.

Billon can be used to make furniture and 'other objects' at a [[Metalsmith's forge]]. However, know that it is not [[magma-safe]].

== Empty DF:2012 Articles ==

Hello, I'd like to offer a few suggestions:
* Could the bot which went through and replaced all the v0.31 article links with DF:2012 links be modified to actually create those articles with a <nowiki>{{av}}</nowiki> template inserted, so that users can reference an older version easily while understanding that it could be outdated?
* Could a bot be created to go through all the current dead links and create those articles and place a <nowiki>{{av}}</nowiki> template within them?
* Failing that, I'd be willing to volunteer for this; I understand that I should talk to you for article creation. In that case, would I have to present you with a list of articles to be created?
--[[User:Reilwin|Reilwin]] 02:53, 15 March 2012 (UTC)

:Looks like I can create articles myself after enough edits. --[[User:Reilwin|Reilwin]] 06:35, 3 April 2012 (UTC)

== Spanish translation ==

Hello! I'm a Spanish player of this game and I would like to begin the translation of this wiki into Spanish. I hope you like the idea! Regards.

== PROBLEM ==
since you "upgraded" the wiki, sometimes when i try to load a page, any kind of page in the wiki, instead of loading the page, my browser (chrome) starts downloading a file like this: DF2010-Magma.gz
the file never ends downloading and it contains nothing, so i dont know whats the deal with that, sometime is loads teh page as usual
*Take a look at [http://www.bay12forums.com/smf/index.php?topic=96229.0 this forum thread] - most cases seem to result from using Avast Antivirus along with Google Chrome. --[[User:Quietust|Quietust]] 00:38, 10 February 2012 (UTC)

== Upload Button Missing ==
Hello. I've uploaded [[http://dwarffortresswiki.org/index.php/File:DA_Quarters.JPG,stuff]] before, but the upload link seems to have vanished for me. (I'd like to upload a small .exe file which makes the depot tradeing semi-automated so I can link to it from my user page.) What should I do?

Thanks,
--[[User:DDR|-DDR]] 01:28, 19 February 2012 (UTC)

Update: Oh, so it's just down for a few days? OK, I'll be patient. Thanks for all the work you've done here, Emi. :)

== Eagles ==

Why can't I create new pages? I want to create a page about normal eagles.

: This wiki is going through a lot now. New name space for the latest DF version has been created and articles are copied to it, as far as they are still valid for the new version. Also this wiki's cluster size has been increased by two new servers and many things around it are being configured. So I think the admins just prohibited new article creation for a while until they sort things out. --[[User:Nagidal|Nagidal]] 17:31, 19 February 2012 (UTC)

: I've seen Briss has created the Eagle page, maybe it's so that you can fill it with content. --[[User:Nagidal|Nagidal]] 18:50, 19 February 2012 (UTC)

== a namespace just for me? ==

It says that if i'd like a user page i should post here asking for one.
can i have a namespace for me please? under Zazq? [[User:Zazq|Zazq]] 21:48, 19 February 2012 (UTC)

: A namespace is not the same as a user page. I'm almost sure you can't have a namespace just for you, but you can certainly have your own userpage where you can set up your own sandbox. I have created you your userpage, just click on the link on your name in the signature. You can start forging some good articles on your userpage. --[[User:Nagidal|Nagidal]] 23:46, 19 February 2012 (UTC)

== UserPage ==
could i have a page too? to edit and try stuff before posting ... Edit: it is Mohreb by the way ...

I'd like a user page too, name KevinFragger2427. Thanks.

== v34 Utilities ==

Can we get a [[DF2012:Utilities]] page created?

== Giant sponges ==

Hello, I am new to this wiki and I would like to add articles for giant sponges and giant mosquitoes.

I trust I can just copy-paste the old tags from a DF2010 creature page and change them accordyingly ?

[[User:Naryar|Naryar]] 11:28, 23 February 2012 (UTC)

== Can I have two pages created? ==

I'd like to have two pages created for me, please.

1. I'd like my user-page created, so I can do all the other cool stuff that people do with their user-pages.

2. I would also like a whole new mod article made, please. Title it "Modern Warfare: Year 2100" too, please, as well.

EDIT: Username is UristMcHuman. Sorry I forgot that

== Interactions. ==

I would like a page created under 2012:Interaction, please and thank you. [[User:Lofn|Lofn]] 15:54, 25 February 2012 (UTC)
EDIT: a userpage/sandbox would also be very much appreciated, if you find the time.

== User page for Darchitect. ==

I'd like one, if you'd be so kind.
[[User:Darchitect|Darchitect]] 20:24, 29 February 2012 (UTC)Darchitect

== Favicon Recovery ==

I notice the favicon seems to have gotten lost somewhere along the way. Since I'm the one who initially made it using the main site logo for reference, I still have a copy sitting around. [http://dffd.wimbli.com/images/dfwiki_favicon.ico Here it is, feel free to use it again.]

== Request for User Page ==

Hi there, can you please add a user page for me? Thank you. [[User:Timtek|Timtek]] 11:47, 5 March 2012 (UTC)

== Request for Confirmed User ==

I was wondering what I need to do to be able to upload a file. I registered four days ago, and have been waiting to become an "Autoconfirmed user" so that I can add my tileset to the Tileset repository. The "autoconfirmation" never comes, however. Attempting to google the issue said that I should be autoconfirmed after 3 days, which has not occurred. Am I missing something? --[[User:Taffer|Taffer]] 13:10, 6 March 2012 (UTC)

Hello again! Thanks for the help earlier, and sorry for the second message. Would it be alright if I have a user page? Thank you! --[[User:Taffer|Taffer]] 18:51, 7 March 2012 (UTC)

== Cached Special Pages ==

The wiki currently has [http://www.mediawiki.org/wiki/Manual:$wgMiserMode $wgMiserMode] enabled, resulting in a number of [[Special:SpecialPages|special pages]] having their results cached (by MediaWiki itself) to reduce server load, but there's no cron job to run /maintenance/updateSpecialPages.php and actually update those pages - as a result, they're all 3 months out of date. I've mentioned this at least 3 times on IRC but it still hasn't been fixed. --[[User:Quietust|Quietust]] 20:24, 7 March 2012 (UTC)

== Is the DF2012:Creatures page getting too big for the server? ==

The Creatures page still needs to be updated with the new creatures for the lakes/rivers but when I try to submit or preview tha page I get a blank page and a submitted update is not visible on the page. Is the page simply too big now, or is there some server side changes that can be made to fix this? [[User:Organised chaos|Organised chaos]] 20:18, 13 March 2012 (UTC)
*If you ask me, the Creatures page is currently being done '''all wrong''' - it should only list each creature '''once''' and include the relevant biomes, rather than copy/pasting it for every single biome (and introducing errors when one entry has different values from the others). --[[User:Quietust|Quietust]] 21:00, 13 March 2012 (UTC)

== DFRawFunctions ==

I've got an update for DFRawFunctions (corrects behavior for a few functions and adds new features to some others) which also includes a few new raw files - when you've got a chance, pull 'em from github. In fact, some option to automatically pull updates from github either periodically (once or twice a day) or on demand (e.g. editing a particular wiki page) would be really nice so I won't have to bug you about it. --[[User:Quietust|Quietust]] 18:27, 18 March 2012 (UTC)

== I want to make Korean Wiki. ==

I was looking for administrator to discuss this, but I couldn't find anyone... also, I'm not sure that I should talk it to you. anyway, I leave this here.

I want to make Korean Wiki, There're some Korean fan, but they hardly play the game because of the lack of game information. So I thought They need wiki to know the game. I want to know whether the administrator can found Korean version of this wiki or not.

How can I get the permission about it? Is it needed that something to verify myself to them? I hope I would take a positive answer. --[[User:Tragal|Tragal]] 14:44, 30 March 2012 (UTC)

== Create Redir [[DF2012:Well_guide]] ==

Need a redir or crosslink created from: [[DF2012:Well_guide]] (empty page) -> [[v0.31:Well_guide]]. And/or snap relevant links. --[[User:Kim Bruning|Kim Bruning]] 08:37, 24 April 2012 (UTC)

== Froot wants a userpage too. ==

Hey-lo.
Yet another userpage request.
[[User:Froot|Froot]] 02:08, 1 May 2012 (UTC)

there is no "DF2012 Talk:Cave crocodile", added an my issue about my "Bosa, Cave Crocodile (+trained+)" which cost me about an game-hour lost due to reloading save in the article. Wonder, why there is no "talk" pages for everything by default? There are many cases which need some science before editing articles :(

== Minecarts 101 page? ==

Can we get a "Minecarts 101" page started the same way there are intro pages for things like the military?

Thanks,

v0.34:Memory (computing)

2012-04-04T13:48:53Z

Dhokarena56:

Memory is used for storing values and states in dwarven [[computing]]. Typically, binary memory is used, but this isn't strictly necessary. There are multiple ways to set up a memory cell, depending on whether one is using [[mechanical logic|mechanical]], [[fluid logic|fluid]], or [[creature logic]]. With binary memory, each cell has two possible states, generally referred to as 0 and 1, or true and false.

===Performance===

Memory systems in dwarf fortress, thankfully, are very good at maintaining their value (in the absence of any [[troll]]s), but they are still plagued by problems with latency and long refractory periods. Latency refers to the length of time before which a change in value will register, and the refractory period refers to the period after writing to memory during which one cannot reliably write to it a second time. Because of the delays involved with [[pressure plate]]s, latency and refractory period for a given memory cell often depend on which state the memory is being changed to. For instance, the mechanical hybrid cell below has nearly no latency when being written as true, but around 100 ticks of latency when being written as false.

Some designs can trade simplicity or material needs for costs in performance.

==Fluid Logic==
The simplest fluid logic latch relies on an infinite source and infinite drain, storing information in the form of the presence or absence of water in a particular location.

{{diagram|spaces=yes|
═════
[#0F0]~[#FF0]X[#F0F]^[#FF0]╬[#0FF]~
═════}}

In this design, water flows from an infinite source {{Raw Tile|~|#0F0|#000}} over an output [[pressure plate]] {{Raw Tile|^|#F0F|#000}} toward an infinite drain {{Raw Tile|~|#0FF|#000}}. Its flow is controlled by a [[floodgate]], {{Raw Tile|X|#FF0|#000}}, and a raising [[bridge]], {{Raw Tile|╬|#FF0|#000}}, both linked to the same input. When {{Raw Tile|X|#FF0|#000}} and {{Raw Tile|╬|#FF0|#000}} are open, water will cover {{Raw Tile|^|#F0F|#000}}; when they are closed, there will be no water. Thus, the input source toggles the state of the memory cell, and the state of the memory cell is reflected in the output of {{Raw Tile|^|#F0F|#000}}.

This is an example of flip-flop memory. The state of the memory can be toggled, but it's not possible to write one particular state (that is, for instance, true) to the memory without first examining the memory. This can be altered by replacing the bridge and floodgate with independently triggered doors. This design has relatively high latency, because of the flow rate of water, and a refractory period of 100 ticks, representing the delay associated with bridges and floodgates. Given careful enough design and sufficient water pressure, the latency of a write to true can approach 100, with the latency of a write to false around 120.

==Creature Logic==
{{diagram|spaces=yes|\
╔═╗
═══╝[#0F0]┼╚══
[#F00]p[#FF0]¢[#FF0]^[#FF0]¢[#00F]¢[#F0F][#00F]^[#00F]¢[#F00]p
══╗[#0FF]┼╔═══
╚═╝ }}

In this circuit, a creature placed between in the middle seeks its [[path|pathing]] goal {{Raw Tile|p|#F00|#000}} but is constrained by the [[hatch cover|hatch]]es {{Raw Tile|¢|#FF0|#000}} and {{Raw Tile|¢|#00F|#000}}, each linked to the pressure plate {{Raw Tile|^|#FFF|#000}} of the same color. When the door {{Raw Tile|+|#0F0|#000}} is opened, the creature can move to the left (false) {{Raw Tile|^|#FF0|#000}}, and when the door {{Raw Tile|+|#0FF|#000}} is opened, the creature can move to the right (true) {{Raw Tile|^|#F0F|#00F}}, thus outputting to anything linked to that pressure plate. This is an example of memory for which it is possible to write a particular state, rather than just toggling, which allows for simpler design for some applications. Note also that rather than writing on a single on or off signal, it depends on an on-off cycle.

This design has good latency for creature logic systems, resulting in on signals around 40 ticks after writes and off signals around 150 ticks after writes. It has a 110 tick refractory period, representing the time necessary for the hatch covers to close.

Another creature-based logic design is discussed in [http://www.bay12forums.com/smf/index.php?topic=106498.0 this forum post by dhokarena56]. Because it is only one tile wide, although it is much longer than, say, the fluid latch, many can easily be built in sequence given a few good mechanics, a good supply of mechanisms and a little time. It requires a couple of puppies or other domesticated animals and a disarmed, non-building-destroyer hostile creature.

==Mechanical Logic==
A [[gear assembly]] can function all on its own as a memory cell, being either active or disengaged. However, some complicated applications suggest the use of hybrid mechanical-fluid memory.

{{diagram|spaces=yes|\
z+2
╔═[#0F0]☼╔═╗
║ [#0F0]%[#0A0]% ║
╚═╝╚═╝}}
{{diagram|spaces=yes|\
z+1
╔═[#FF0]☼╔═╗
║ [#AA0]%[#FF0]%[#F0F]^║
╚═╝╚═╝}}
{{diagram|spaces=yes|\
z+0
╔═╗
║[#00F]~║
╚═╝}}

In this design, two separately powered [[pump stack]]s, {{Raw Tile|%|#0F0|#000}}{{Raw Tile|%|#0A0|#000}} and {{Raw Tile|%|#AA0|#000}}{{Raw Tile|%|#FF0|#000}}, are placed over each other-- the lower one, pumping to the right, and the higher one pumping to the left. When the water {{Raw Tile|~|#00F|#000}} is lying in the rightmost (true) cell, it activates a pressure plate {{Raw Tile|^|#F0F|#000}}. To write true to the memory, one triggers the lower gear assembly {{Raw Tile|☼|#FF0|#000}}, activating the lower pump, and to write false, one activates the higher gear assembly {{Raw Tile|☼|#0F0|#000}} and pump stack. Like the creature logic memory above, this cell can be written as specifically true or false, and depends on an on-off cycle as input.

This design has very good latency (from almost nothing for a write as true to 100 ticks for a write as false) and no real refractory period-- it can be written to immediately following a previous write, although it does depend on the completion of the previous write signal (receiving the off component of the signal) before writing again.

==Memory addressing==
In complicated designs, one may wish to use a memory cell abstractly-- to represent any number of different values. To use multiple such abstract cells, it's necessary to specify exactly which memory cell one wishes to read from or write to at any given moment.

This is simplest in mechanical logic. A grid of gear assemblies can represent rows and columns, and by disengaging control gears for all but the cell that lies at that particular row/column intersection, one can easily refer to a specific cell. Strict fluid logic can do something similar, by controlling the input of water to memory cells, although this involves long delays. With the creature logic design, one can use additional doors to restrict writes to any cells not referenced.

==Alternate design==
Because most memory is used for a specific application, there is no single best design. It is not uncommon to see functionality built into memory circuits-- a simple circuit that increments contains its own memory. Alternate designs are important when memory needs to be written to in various ways (toggle versus specific value), when it needs to receive different kinds of input (a steady on or off versus an on-off cycle), or when latency and refractory period are unimportant compared to resource requirements such as space.
