Looking for Wikipedia pages

(from the Village Pump) I'm looking for the page that directs the "Did You Know?" section on the front page. Who decides what we see there?

I also want to know if there's a New pages patrol, just like the RC patrol.

Anyone with info please contact me hear or at my talk page. MGM 10:20, May 15, 2004 (UTC)

Template:Did you know is shown in the main page, and Wikipedia:Recent additions is the history thereof. The rules are in the corresponding talk page MediaWiki talk:Did you know. Wikipedia:New pages patrol is for the new pages patrol, but it's rather quiet over there. -- Chris 73 | Talk 02:01, 16 May 2004 (UTC)

Egyptian cat

It's probably an odd question, but I'd really like to know. Ancient Egyptian could simply use the drawing of a cat to represent the word cat, but suppose they used the hieroglyphs to represent the sounds of the ancient word for cat, what glyphs would they use? Mgm|^(talk) 11:28, Mar 11, 2005 (UTC)

The hieroglyphs for cat, miw, combine the glyphs for m, i and w with a picture of a cat. For a picture, see here (search for "picture of a cat"). - Nunh-huh 01:58, 12 Mar 2005 (UTC)

• Thank you. Much appreciated! Mgm|^(talk) 10:07, Mar 12, 2005 (UTC)

I thought I'd chip in that Wikipedia can deal with Egyptian hieroglyphs: the word for cat is:

which must have sounded remarkably like 'miaow'! --Gareth Hughes 23:32, 14 Mar 2005 (UTC)

Peer review discussions

Mummy

I've recently done an extensive rewrite, moving sections around, rephrasing the lead and making a clearer distinction between artifical and natural mummies, adding pics, refs and ext. links and most of all a description of the Egyptian mummification process. I know it's not finished or feature-able yet, but I'd like some opionions on what still needs to be included. I'd specifically like opinions on whether I should include a short section on a few of the listed mummies linking to their main article above it. -- Mgm|^(talk) 15:19, Mar 26, 2005 (UTC)

I think it should talk about what happened to mummies after they were buried. In various regions, mummies were considered to have magical and medical properties, and were used for medicine. It had been widely used in China as a part of Traditional Chinese medicine. I'm also going to add the mummification practice in Japan. Revth 03:15, 30 Mar 2005 (UTC)

Magical and medicinal purposes should indeed be mentioned and I welcome the addition of the Chinese mummification process. 131.211.210.15 07:37, 30 Mar 2005 (UTC)

Basically, it is too short. 'Mummies in Ancient Egypt' should be at least 30kb by itself, and in this article I see it as much larger with a subarticle. 'Mummies in modern times' should go after 'Mummies in other civilizations', and the latter, together with 'Famous mummies' need expantion from a list into large sections. Finally, the 'Famous mummies' should be cleary divided into real mummies and those popularised by books/films/etc. Which reminds me, there needs to be a Mummy (disambigation) (for the film, at the very least). --Piotr Konieczny aka Prokonsul Piotrus Talk 12:36, 2 Apr 2005 (UTC)

(Copied from my talk page). --Piotr Konieczny aka Prokonsul Piotrus Talk 12:02, 5 Apr 2005 (UTC)

1. "Mummies in Ancient Egypt" probably should be expanded as you said, but what do you think needs to be included?
2. "Mummies in modern times' should go after "Mummies in other civilizations". That's a good idea. I'm not really sure about expanding the list yet. After all, they do have articles on their own, and the article may end up being too large if I do. I'm hoping to keep the mummy article as general as possible.
3. Finally, the 'Famous mummies' should be cleary divided into real mummies and those popularised by books/films/etc. If there are any fictional mummies listed, please point them out.
4. I'll see what I can do about a disambiguation. Wikiwax showed me there's a lot of mummy topics floating around.

Cheers! Mgm|^(talk) 11:25, Apr 5, 2005 (UTC)

Re1. I am not a mummy specialist, but it is just way to short. I suggest some research and reading. After all, when people think mummy, they most of the time think 'mummy from AE'. For now we have 2 screens worth of info - good for an introduction, but I am sure a detailed article could have several times that info. Re2. Well, atm the article is too short, so I suggest expanding anything. We can worry about it being too long when it is no longer too short :) Re3. Hmmm, I thought that they would be added. As long as there are none, well, ignore this comment :) Re4. What is wikiwax? --Piotr Konieczny aka Prokonsul Piotrus Talk 12:02, 5 Apr 2005 (UTC)

Dalek modulation

What kind of program do I need to use the plugin on? I think I can dig up a microphone to use... - Mgm|^(talk) 13:34, July 22, 2005 (UTC)

That's probably where you are going to have to experiment a little. The straightforward answer is pretty much any version of Cubase, but they can get expensive. Cubase VST is available on a demo license. However, although the VST plugin protocol was developed by Steinberg its now quite widely supported on Mac and PC music software. According to the VST article there are even Linux based VST hosts now, but I don't know whether plugins always work accross platforms.

Basically all you should need is a simple recording environment that supports VST plugins. Record your voice, then experiment with applying the ring-mod plugin to it. A search for 'free VST host' leads me to MiniHost which might do the job - it appears to have the right features, but the screenshot doesn't look like anything I would expect though it might be showing an example of hosting a synth plugin.

There must be other alternatives too. You could probably find a free Ring Modulator for other plugin standards like DirectSound that should work with Windows sound programs such as MediaPlayer. -- Solipsist 15:07, 22 July 2005 (UTC)

Yup, a Combination of MiniHost and the BJ Ringmodulation plugin works quite well. I had to also download the ASIO4All drivers mentioned in the MiniHost documentation to get my weird DSP microphone to work, and for some reason I only get a bunch of sliders instead of the pretty control panel for the Ring-mod, but it gets the job done. Now I can sound like a dalek in real-time and also record the results. To be honest I'm not sure whether I sound more like a dalek or a cylon, but with a reference sample, a bit of tweaking and a bit of acting you can probably get quite close. -- Solipsist 18:01, 22 July 2005 (UTC)

I've got the program up, but it doesn't see any input channels. I've got an ancient mic that's labelled "MDE Uni-directional Dynamic Mic Impedence 600 Ohm DM - 202". Do you know of any drivers for the thing, or is it too old to be computer compatible. (No I don't have any manuals for the thing anymore). Thanks for the help so far! :) (Once we're done, please copy this to my discussions archive page (User:MacGyverMagic/Discussions), or leave it for a while so I can do it). - Mgm|^(talk) 20:15, July 22, 2005 (UTC)

I'm not sure. The mic itself probably doesn't matter so much. I guess you are plugging it in to the mic input on your sound card. So you really need the ASIO driver for that make of sound card. If it is a hi-tech sound card the manufacturers might produce their own ASIO drivers, but if it is a SoundBlaster or generic motherboard soundcard the ASIO4All driver will probably do it. There is a link to ASIO4All in the MiniHost documentation. Although even then it didn't work at first for me - I think I had to select the right input and output driver on the ASIO menu of MiniHost.

I also downloaded a simple VST instrument plugin so that I could generate sounds from inside MiniHost, which made it a little easier to tell when I had got the sound card/driver settings right. -- Solipsist 20:28, 22 July 2005 (UTC)

User:MacGyverMagic/monobook.js

Could someone check my monobook skin and tell me why the "changes since I last edited" and "purge tab" aren't showing up when the "edit section 0" does? Also, clicking my vfd tab tags the article, but fails to open additional screens for the nomination process and I'm not made aware of any popup blocks. Last time I checked, block tabs had no problem, so popups should be fine anyway. Can anyone enlighten me as to why things aren't working properly? I'm currently working with IE and unfortunately, that the browser I have most access to (so using Firefox would not be a solution to the problem). Thanks in advance. - Mgm|^(talk) 09:15, August 16, 2005 (UTC)

• I'd also like to know on what type of pages the tabs should show up. - Mgm|^(talk) 09:47, August 16, 2005 (UTC)
  • The addPurgeTab() and addSinceTab() functions use a different version of addlilink() than do_blockip_stuff() and add_blocktab() do. (I'm not sure if they both use the same version, since I'm too lazy to look at the referenced user scripts.) You need to copy the other version of addlilink() in, and rename one or the other (both in the function declaration and where it's called).

    I don't know why autovfd doesn't work in IE, but User talk:Korath/autovfd.js does warn you about it right at the top. —Cryptic (talk) 14:36, 16 August 2005 (UTC)

Downloadable detective games

I can remember two old DOS mystery games one set on a zeppelin and one set in a big mansion. In both games you are joined by several characters among who is a murderer who is killing of the characters. The player's goal is to collect clues and question suspects to find the murderer. Can someone tell me what these games were called and if it's possible to get a free download of either and whether there's similar games I might be interested in? I prefer games that can be played by Pentium 166 MHz machines. -Mgm|^(talk) 21:19, 3 November 2005 (UTC)

The first one is probably Murder on the Zinderneuf. You can download it (if you already own a copy—don't pirate software! ;-) from Home of the Underdogs [1], which also cross-references similar games that might interest you. I don't know about the second, but you might be able to find it in their list of mystery games. —Charles P. (Mirv) 21:34, 3 November 2005 (UTC)

• Thank you very much! The first one is indeed Murder on the Zinderneuf. Any other tips are also welcome. If anyone knows a site with a working download of "Murder Mansions" or "Mansion Murders" I'd really like to know. - Mgm|^(talk) 21:41, 3 November 2005 (UTC)

The second one seems to be Deadline, which was made by the defunct company Infocom in 1982. The palyer is placed in the role of a police detective who must solve the murder of Mr. Robner, a wealthy businessman. http://en.wikipedia.org/wiki/Deadline_%28computer_game%29

• Killer bees are always popular. Black Carrot 07:16, 16 January 2006 (UTC)

• Unless fire ants are in some way very different from other ants, they don't sting. They bite and then spray some nasty chemical on the wound. Which means the article is wrong, so I pointed this out on the talk page. And spiders don't sting either, I believe. And, while I'm at it, neither do mosquitoes, although the mouth they bite with is rather needle-like. DirkvdM 09:42, 16 January 2006 (UTC)

Morphine

For a piece of fiction I'd like to know at what dosage morphine is lethal, but neither the Wikipedia article nor Google is very forthcoming (I get LD50 values for codeine on the same page). Can anyone give me a rough estimate and tell me how many % medical solutions of morphine usually are? For this particular piece of fiction, I need to know if morphine can be lethal in small volumes of say 1-5 ml. - Mgm|^(talk) 21:42, 6 February 2006 (UTC)

By the way, the main cause of death for most opioids is due to respiratory depression. If the person has been taking the drug for a while, they may become tolerant to these effects. Basically, if your fictional character has been taking the drug for a while and has become tolerant, it might take more than your average lethal dose to remove him/her from the stage. --Uthbrian (talk) 03:03, 7 February 2006 (UTC)

You could consider a stronger opiod such as demerol. - Cybergoth 03:06, 7 February 2006 (UTC)

The question about the film with the drowning kid above, brought to mind another film. In it, a boy is talked into jumping of (I think) a railway bridge by his older brother and his brother's friend, but when he jumps, a log comes from under the bridge and he lands on it on his back. He would've drowned if it wasn't for the kids saving him, but he ends up paralyzed in a wheelchair. The rest of the story involves the older brother's feelings of guilt, a doctor who examines the kid for the possibility of a risky operation falling in love with his mother. I think the older brother may have been played by Brendan Fletcher or Kevin Zegers, but it could be someone else entirely. Has anyone got an idea which film I'm talking about? - Mgm|^(talk) 09:07, 2 June 2006 (UTC)

Cuisine recommendations

(transcluded from my Userspace - Mgm|^(talk) 14:36, 3 September 2006 (UTC)) Every once in a while I like to go mad with cooking and make something my family doesn't normally cook. We usually have veg, meat, potato dishes and we also eat a lot of Italian and Eastern dishes. I just made onion bahjis which went down pretty well, but now I'm looking for inspiration for my next outburst. What cuisines should I consider and what are the particularly tasty dishes in those cuisines. I just want a few guidelines to dish names and ingredients. I'll google (or visit the wikicookbook) for recipes myself. Any help is appreciated. --Mgm|^(talk) 18:40, 2 September 2006 (UTC)

Most tapas is pretty easy to cook. I find tortilla de patatas very easy to make (if you're patient): served with a simple green salad and balsamic vinagrette it's great. -- Finlay McWalter | Talk 18:45, 2 September 2006 (UTC)

• You're right that does sound tasty. Any other suggestions? - Mgm|^(talk) 19:56, 2 September 2006 (UTC)

Cajun is pretty easy to do well: gumbo, jambalaya, dirty rice... If you're in the States I'd suggest the Zatarain's mixes to start although I usually add extra vegetables: always okra for the gumbo, frozen if your local store doesn't sell the vegetable fresh. Works well with chicken, sausage, or shrimp (or if you're like my cousins in Louisiana, just dig up some crawfish from the backyard). Durova 20:37, 2 September 2006 (UTC)

North African and Middle Eastern cuisines are both rich in tasty dishes, and pretty easy to make (if you're already eating Eastern dishes you may have all the requisite spices). Very healthy too.

I've developed an addiction for the game at http://www.blackflip.org Some of those puzzles are particularly devilish and I wondered what math applies to puzzles like this. Maybe reading up on those theories and rules makes solving some of them easier. - Mgm|^(talk) 08:48, 17 October 2007 (UTC)

Well I took a look at those puzzles, very addictive indeed. I think graph theory would help but It seems the most difficult part is deciding what color each horizontal row should be, based on the layout. In general, the study of problems like these falls under game theory. I also think analysis (mathematics) and perhaps Galois theory may help, but those are inherently more advanced and thus less easily understood. A math-wiki 11:27, 17 October 2007 (UTC)

I've a feeling a similar sort of logic to the Seven Bridges of Königsberg may prove to be of some help. To start workout what are illegal moves, for example you can't move horizontally from black to white. They you could try exaustive enumeration of simple 2 by 2 and 3 by 3 sub-grids, for example if you have a t-shape will imply something or other. game theory may be a readherring as the sort of games studied there are more like poker than strictly logical one, all though some ideas like the Decision tree may be of help. --Salix alba (talk) 14:22, 17 October 2007 (UTC)

This comes under combinatorial game theory in some sense, but I doubt that's a very useful observation. math-wiki: how on earth do you intend to apply Galois theory to this situation? Algebraist 15:46, 17 October 2007 (UTC)

Never mind Galois theory. Analysis, which I presume to mean mathematical analysis? Isn't that the polar opposite of what we have here? Salix has already commented on game theory, but I would like to emphasize that the study of problems like this certainly does not fall under what is usually called "game theory".

A math-wiki, your enthusiasm to provide help is appreciated, but perhaps some more reflection about whether your suggestions are truly relevent is in order? -- Meni Rosenfeld (talk) 21:28, 17 October 2007 (UTC)

After playing for a bit, I suspect a logic based way to solve these puzzles can be very useful. You can look at small subgrids of the whole puzzle and make certain logical conclusions. "If I'm ever going to make this square black, I'll have to come from there, so that row will need to be white. If I go over this square, then that becomes unreachable, etc". You can probably formulate a basic set of rules like this, and based on that you can determine for some subgrid a small set of possible paths to take along it. Once you run out of logical rules to apply, you can search the possible paths that are left exhaustively. If you have some paths left for each 3x3 grid, there will only be very few ways to combine those into one full path, if your set of rules is good enough, you will only have a few paths left to check. risk 18:34, 17 October 2007 (UTC)

(after edit conflict) Heres a partial method. Consider a game with n-rows. For the final state each row can be either all black or all white hence there are 2ⁿ possible final state. For each such final state mark the differences between the final state and the starting state with an X. A few things are imediatly obvious, each X must be connected by X's to the edges of the grid (or all X's are connected, but don't touch the edge). Next count the number of dead-ends, that is X's with only one imediate neighbour, here the edge of the board can be counted as X's. There can be at most 2 of these and if they exist the dead ends much be starting or ending points. Similarly T shapes and + shapes count as 1 and 2 end points. Once you eliminate the impossible final states you would have a much smaller set of possibilities. --Salix alba (talk) 19:11, 17 October 2007 (UTC)

Ok, so i only understand Galois Theory vaguely, my reference to analysis is mainly to constructivist analysis (again only a vague understanding), but from the description it would seem to have something to do with constructing the possible solutions from allowable moves.

After having played a lot more, here are a few nifty shortcuts. If your puzzle has one color in such a pattern that their are at most two dead ends (that is say a black square with three white ones adjacent to it) then it is basically analogus to a Hamiltonian circuit. the solution is generally very easy. If you have a one or more diagonals, try pathing right next to it, and then next to the path you created (a stair-step pattern). And if you have one vertical the is opposite colors it neighbor, you can usually solve these by pathing down the vertical (e.g. if you have a checkerboard pattern somwhere) With these few tricks and some logical thought, I can already solve most easy ones in under a minute and most moderately difficults ones in a few minutes tops.

I think it is a rip of Polarium, there is an acknowledgement of it at the bottom of the page. --Salix alba (talk) 07:29, 18 October 2007 (UTC)

I think I have a preliminary technique for finding general solutions. Consider the flipable rectangle, and m*n rectangle, that means your graph is an (m+2)x(n+2) set of vertices (remember that you can use the edge). All the vertices are linked in a "square lattice." There are $2^{n}$ possible combinations of colors, meaning that their are that many graphs to analize in total, but it is often possible to cut down on that number significantly. What your do to create these graphs is select one of the color combinations and mark all the vertices that need to be flipped. Then look to see if the graph (including the extra edges) has a path sure that the degree of all but 2 of the vertice is 2, the two should be degree 1 "Hamiltonian Case"(unless the path starts and stops next to itself "Euler Case"). This may not be a general solution but it definately comes close. The one thing I have not throughly investigated is how the edge squares which are used "at will" affect possible paths, but it would seem to allow a few different choices for the pather, so they all should be checked.

Upon putting it to the test, the restriction that the degree need be 2 is not actually the case, just as long as those with degree 3 are adjancent and have their 3rd edge on the same side so that your can parallel your earlier path. All in all, logical thought is still the most efficient. A math-wiki 00:39, 18 October 2007 (UTC)

Hamiltonian Case should be called Hamiltonian path Case, and Euler Case should be called Hamiltonian circuit Case. A math-wiki 00:54, 18 October 2007 (UTC)

It seems likely to be NP-complete, as it's closely related to finding Hamiltonian paths in a grid graph (A. Itai, C.H. Papadimitriou, J.L. Szwarcfiter, Hamiltonian paths in grid graphs, SIAM J. Comput. 11 (1982) 676–686.) If so, there wouldn't be a simple strategy that would be guaranteed to always work: you'd have to actually think to solve it. —David Eppstein 07:47, 18 October 2007 (UTC)

Identifying child stage actor

Who starred as the Artful Dodger alongside Gwion Jones and Jodie Prenger in Children in Need 2008? - Mgm|^(talk) 19:35, 16 November 2008 (UTC)

This link seems to suggest it was Robert Madge (a Google search of "Robert Madge" Oliver brings up a load of stuff). I was browsing the Reference Desk roughly ten minutes ago and saw this question, but couldn't answer it. I went onto the other (linked) site and suddenly saw the post!

Stunt kids

I'm not sure if it's even legal. Occasionally, kids perform their own stunts when they appear in a tv show or a feature film, but are there any kids employed as professional stunt performers anywhere in the world? And if so, who is the youngest one? - Mgm|^(talk) 19:35, 16 November 2008 (UTC)

This link says that there's an 11-year-old in Australia who does stunt work. This claims that there was a 3-year-old stunt performer in the 40s and 50s in the US named Thom Bresh. Little Red Riding Hoodtalk 21:51, 16 November 2008 (UTC)
