Turing

I wanna learn the basics of programing on turing. Can anyone recommend a good starting online tutorial or help. Thanks —Preceding unsigned comment added by 69.156.52.228 (talk) 00:31, 6 September 2007 (UTC)[reply]

See Turing machine. There is no tutorial for programming one because, in general, they do not really exist. Models are built from time to time just for fun. Under normal circumstances, they are theoretical devices used in fields such as discrete mathematics and automata theory. -- kainaw™ 02:33, 6 September 2007 (UTC)[reply]

The questioner may have been talking about Turing (programming language) — Matt Eason ^{(Talk  Contribs)} 02:35, 6 September 2007 (UTC)[reply]

Yea, my question is about the "Turing (programming language)". —Preceding unsigned comment added by 65.93.133.237 (talk) 11:27, 6 September 2007 (UTC)[reply]

iPod and itunes

should I play songs bought from itunes in my iPod or can I play any mp3 file in my computer in iPod? What is the case in other company players like Zune and creative and samsung mp3 player? —Preceding unsigned comment added by 59.96.141.253 (talk) 09:31, 6 September 2007 (UTC)[reply]

You can add any mp3 on your computer to your iTunes library, which will add it to your iPod when you sync. You don't have to buy music from the iTunes store at all if you don't want to. Other players won't be able to play songs bought from the iTunes store (except maybe iTunes Plus files, if the player supports AAC), but they'll be able to play mp3s from your computer. — Matt Eason ^{(Talk  Contribs)} 11:40, 6 September 2007 (UTC)[reply]

You can however generally convert files into a compatible format; not always easy if DRM is involved as Matt said. --jjron 08:38, 7 September 2007 (UTC)[reply]

Neither Windows Live Messenger or live.com is working for me

I haven't been able to log into Windows Live Messenger all day and now I'm not able to even go to live.com. Can someone who's not me go there to see whether they have some sort of problems with their server or something (although that seems unlikely) so that I can be sure the problem is on my end. Thanks! --Oskar 13:15, 6 September 2007 (UTC)[reply]

Assuming that you are from Sweden and having Telia as your ISP this IDG article] may interest you. You just have to wait until the ISPs fix this problem. Jeltz talk 14:46, 6 September 2007 (UTC)[reply]

It is also likely that users of other Swedish ISPs and maybe even ISPs in other countries that peer with Telia may experience the same problems. For example Com Hem is affected too. Jeltz talk 14:48, 6 September 2007 (UTC)[reply]

Yeah, that's it! I can't access any microsoft website (I'm using Com Hem, which uses Telia's network) although I haven't had any problems with other sites (wikipedia obviously works). I guess I'll turn on TOR or something in the meantime. --Oskar 14:51, 6 September 2007 (UTC)[reply]

Red Hat Linux update

I'm running red hat linux on my computer. I see an icon on my task bar in the form of a red exclamation mark. When I click it, the OS starts to update. Then I get an error saying my system is not entitled. How do I make my system entitled? Should I pay for my updates? Is there any other easy way for me to update my system? —Preceding unsigned comment added by 202.164.136.62 (talk) 19:05, 6 September 2007 (UTC)[reply]

Why you would pay for anything in the first place I have no idea. Details? Splintercellguy 22:44, 6 September 2007 (UTC)[reply]

Most likely your entitlement has expired. You will not be able to use the Redhat services to upgrade or install packages until you pay for an entitlement. If you are unwilling to pay for software updates, you could always switch to using CentOS, which will give you nearly the same packages, but you're not paying for service or support entitlements. -- JSBillings 13:05, 7 September 2007 (UTC)[reply]

How did type I error in hypothesis testing come be known as "false positive"?

The Wikipedia article on type I error, as well as numerous Google search results, refers to type I errors as "false positives". This appears to run counter the common-sense interpretation of the latter. How did "false positive" come to be equated with type I error? --64.236.170.228 19:32, 6 September 2007 (UTC)[reply]

Evidently your notion of common sense clashes with mine. —Tamfang 20:47, 6 September 2007 (UTC)[reply]

(ec) Because, well, you think you've got a positive result, but it's, um, false. I'm not sure how that goes against common sense. Are you sure you haven't misread what the article is trying to say? The definition given is not the easiest one to follow by far, but at least the example given would seem fairly reasonable:

For example, a test saying a woman is pregnant when she is actually not pregnant is an example of a false positive.

Or do you in fact find that somehow counterintuitive? —Ilmari Karonen (talk) 20:49, 6 September 2007 (UTC)[reply]

Perhaps this clarification: the "positive" comes from the fact that the obtained answer is a "positive" one, e.g., "the test says she is pregnant". The "false" is because the answer is wrong. Perhaps looking at its opposite will help: the test saying a woman (who is indeed pregnant) is not pregnant is known as a false negative. Hope this helps.

Visual Basic menu Click() event

I am trying to write a calculator program in Visual Basic and I would like to have a main menu like those that are common in Windows programs (File, Edit, View, etc.) Anyway, I can't figure out how to handle the MenuItem_Click() event and I can't get a subroutine to handle a click on any item in any of the menus. I tried to figure it out using the help files that came with Visual Studio 2005 (my development software) and the files in the MSDN database, but I keep banging my head against a wall.

Does anyone either know how to program this event, or have some sample source code (maybe from projects of your own.) that demonstrate how to handle the Click() event on a MenuItem? A sample in any programming language would be appreciated.

Here is the code I tried; it's supposed to change the size of the items in the form:

 Public Sub getMenu()
    Dim MenuStrip1 As New MainMenu()        
    Dim mnuView As New MenuItem()       
    Dim mnuView_large As New MenuItem()
    Dim mnuView_small As New MenuItem()     
    mnuView_small.Text = "Small Buttons"
    mnuView_large.Text = "Large Buttons"
    mnuView.MenuItem.Add(mnuView_small)
    mnuView.MenuItems.Add(mnuView_large)
    MenuStrip1.MenuItems.Add(mnuView)
    AddHandler mnuView_small.Click, AddressOf Me.mnuView_small_Click        
    Me.Menu = MenuStrip
 End Sub
 Private Sub Form_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
    Call getMenu()
 End Sub
 Private Sub mnuView_large_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles mnuView_large.Click
    If Me.FontHeight = 8 Then
        mnuView_large.Checked = True
        mnuView_small.Checked = False
        Me.FontHeight = 12
    Else
        Exit Sub
    End If
 End Sub
 Private Sub mnuView_small_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles mnuView_small.Click
    If Me.FontHeight = 12 Then
        mnuView_small.Checked = True
        mnuView_large.Checked = False
        Me.FontHeight = 8
    Else
        Exit Sub
    End If
 End Sub

Again, any and all advice will be greatly appreciated. 69.205.180.123 20:15, 6 September 2007 (UTC)[reply]

I will try and look at one of my old projects in VB.NET and see if I can figure it out. In the meantime I see a probable typo in your code:

    mnuView.MenuItem.Add(mnuView_small)
    mnuView.MenuItems.Add(mnuView_large)
    MenuStrip1.MenuItems.Add(mnuView)

Not that you have added to MenuItem the first time, and MenuItems the second and third. Not sure which is right, but they ought to be the same... --24.147.86.187 22:30, 6 September 2007 (UTC)[reply]

Prohibiting image downloads

Is there a simple way to show images on a web page but keep people from saving them to their hard drives? Basically, I'm setting up a small photography web site for my wife and she'd like to keep people from taking her photos. They're not high res or anything but still doesn't like the idea of them just being right clicked and saved en masse. Dismas|^(talk) 20:31, 6 September 2007 (UTC)[reply]

In a word, no. If they can see it, they can save it. —Ilmari Karonen (talk) 20:39, 6 September 2007 (UTC)[reply]

(after EC) You can put up roadblocks, but there really is no effective way. I think IE lets you mark an image as downloadable, but Firefox just laughs at that setting. And a person can just do a screen print anyway. --LarryMac | Talk 20:41, 6 September 2007 (UTC)[reply]

Some image hosting places do a referrer thing, so that only their site can put it up (that is, only transmit the correct image if the referrer in the HTTP header is some specified server). I'm not sure if that will work to stop the right-click, Save Image As function, but it might. You can fool those if you're tricky, and as LarryMac said, nothing can stop a screen-grab --Oskar 20:59, 6 September 2007 (UTC)[reply]

Actually, I just tried that in firefox and it doesn't work. Sorry, you'll have to live with the pain. --Oskar 21:00, 6 September 2007 (UTC)[reply]

You could add a watermark or something similar, as a deterrent. --Dave the Rave (DTR)talk 21:08, 6 September 2007 (UTC)[reply]

Expanding upon my earlier answer, what you want is essentially Digital Rights Management. That article should do a reasonable job of explaining why it doesn't work very well, not even when you're a major movie studio with astronomical amounts of money to throw at it. There are ways in which you could make saving the images more difficult, possibly enough that most people would not bother. Unfortunately, creating such obstacles tends to be rather difficult in itself, and they also tend to easily interfere with legitimate viewing. Ultimately, the fact is that there's very little difference between viewing and downloading, so it's hard to stop one but not the other. And a determined person will always be able to work around any protection schemes, if only via the analog hole. —Ilmari Karonen (talk) 21:28, 6 September 2007 (UTC)[reply]

Put a watermark on the bottom that links back to the website and has her name on it. Then if anyone does re-use them they'll be advertising for you. Don't worry so much about a few people causally saving photos to their desktop. Professional photo services (CORBIS, Getty Images) can't stop that from happening and they have a lot more to lose from it. --24.147.86.187 22:11, 6 September 2007 (UTC)[reply]

You can at least put a statement on the page where you show the pictures about the copyright, and also inlcude the copyright in the images them selves. This will discourage a few. On the way to make it difficult to save, you could break the image into 16 little tiles and then assemble it on the screen in the html. But there is way to stop it completely! Graeme Bartlett 23:26, 6 September 2007 (UTC)[reply]

You could separate the image into 16x16 grids and have 256 little blocks so you can't save them as easily, but that still doesn't fare well with the screen captures and website retrievers. --Wirbelwindヴィルヴェルヴィント (talk) 23:33, 6 September 2007 (UTC)[reply]

Many of the response before have let the perfect be the enemy of the close enough for jazz. I was tasked with something similar for a photography site dinesfavorites.com. You can view source on the page to see what was done, but the short answer is that I overlaid each of the pictures with a transparent gif scaled large enough to cover the photo. It won't prevent someone from doing a view source to get the picture url, but it keeps the casual user from stealing the picture. As an aside, I was pointed at onemodelplace.com as a site which had some protections for images. When I tried to see what was there, though, I kept getting model pages with nude photos, much to my embarrassment (looking at the site recently, they've done a big redesign on how photos are presented... in any event, I ended up using a different method than the onemodelplace technique since what I did do didn't require a lot of heavyweight javascript). Donald Hosek 00:00, 7 September 2007 (UTC)[reply]

Jim Dines's photographs are lovely, but the protection is pathetic. If they were larger images, I would now have some beautiful nature for my desktop in less than 30 seconds. Nor was a "view source" required. The bottom line remains: if you can see it you can save it. Use a little common sense; to display the image on your monitor, your computer must have the image data in its memory.

Instead, try using the images as teasers and free advertising. If someone likes the image and looks at it again and again with a name and a Web address, eventually they or someone looking over their shoulder may come to buy. Artists want their work to be seen, and they want to make a living; tempting images with ad text can help do both. The aesthetic challenge is how to overlay the ad text without violating the integrity of the image. --KSmrq^T 21:42, 7 September 2007 (UTC)[reply]

Again, I never claimed to have strong protection (personally I think that the pictures are way over-priced and would never buy them... in fact, that particular site was put up because nobody was' buying them!). Just something good enough to keep a casual thief from taking pictures off the site. If it's viewable, it can be downloaded. This provides a relatively low cost way to keep the pictures from being taken from a casual thief. Donald Hosek 00:44, 9 September 2007 (UTC)[reply]

I just visited your site, casually clicked the "disable CSS" button, and saved the image to my hard drive. No big deal. --Carnildo 21:48, 7 September 2007 (UTC)[reply]

As said above, you want DRM. This is wrong, and thankfully it's quite impossible. You want the user's computer to process the image but only in a way that you find acceptable.. unfortunately for you it's their computer and they have control over it. If you're not already discouraged by all these people who know what they're talking about telling you it's technically impossible, consider it on moral grounds. --⁪froth^t 03:18, 8 September 2007 (UTC)[reply]

Note that visitors can only view an image after they have downloaded it (thinking the two are separate is a common mistake). In msWindows, they would be placed under 'temporary internet files', which I have on occasion used as workaround to save 'downloadprotected' images. DirkvdM 09:07, 8 September 2007 (UTC)[reply]

Getting windows licence from installed windows

USB Flash drive giving me flack

I just bought a Sandisk U3 Cruzer Micro USB 2GB flash drive. It came with all sorts of U3 software nonsense on it that not only I didn't want, but I couldn't even use anyway (I run a Mac). After poking around I found a U3 removal utility (http://www.u3.com/uninstall/), and ran it from Parallels (a Windows XP virtualizer). Well, it ran for awhile, then locked up, then crashed. Great. Now I can't use the drive for anything — the Mac OS X Disk Utility thinks it has no partitions and is not writable. In Windows it thinks it has zero drive space free and zero drive spaced used.

I have nothing on the disk, I want to wipe it and reformat it as a single partition. What's the easiest way to do this at this point? I'm immensely irritated with this U3 nonsense (it mounts a fake CD drive when you put it in and then launches all sorts of software—not exactly what one expects from a blank USB drive, and it makes it incompatible with some of the hardware I need to use it with at that) and that it is taking so much time to just wipe this thing.

Disk Utility (OS X) doesn't seem to be able to do it; I tried using the old FORMAT from the DOS command prompt but it gives me "Error in IOCTL call" as a message in response. Blah. The drive mounts, and I can view its driver properties just fine, but I can't wipe it. Arrggg. --24.147.86.187 22:18, 6 September 2007 (UTC)[reply]

OK... nevermind! In removing it and putting in back in a few times it now let me erase and re-partition it in Disk Utility. Phew. WTF. I love it when hardware developers decide to "make things easy" for you by adding junk you never asked for. Just what I wanted, a USB drive pre-loaded with SKYPE and other things that I could have obtained if I had really wanted them! Hey, loading up an OS with extra, unwanted junk worked so well for Windows, why not apply the model everywhere!! --24.147.86.187 22:27, 6 September 2007 (UTC)[reply]

Psst, blame the software developers. --Wirbelwindヴィルヴェルヴィント (talk) 23:28, 6 September 2007 (UTC)[reply]

I understand that U3 may not be for everyone but I use a U3 flashdrive and find it incredibly useful. The apps on it are more stable than most portable programs I use and, despite the odd problem I encounter on the school network I use it on, the U3 apps are very handy. I understand why you might be frustrated by it but U3's not all bad

Mix Lord 12:12, 7 September 2007 (UTC)[reply]

It's the sort of thing I think should be an option to install, not an option to remove. They shouldn't assume I want such a thing, or want it to set up an unwritable partition that pops up every time it is installed, and doesn't even work on my system anyway. Additionally I find it irritating when removable media comes pre-loaded with software — the point is supposed to be that it is blank media, not that it has 20 MB of stuff already on it that is set to auto-launch on insertion. It is a bad approach. If you want to make a useful, "killer app", do so, get the word out, put advertising all over the package; but don't install it automatically. --24.147.86.187 14:20, 7 September 2007 (UTC)[reply]

I also had a sandisk cruzer, and the attitude was just palpable in the software that the developers wanted to give you every possible opportunity to uninstall U3 and the only reason it was preinstalled was because their bosses told them. IIRC one of the auto-execced U3 apps that popped up when I put it in for the first time was actually a U3-signed version of the U3 uninstall utility! --⁪froth^t 03:06, 8 September 2007 (UTC)[reply]

LaTeX pictures

Hi,

I'm trying to write a document in LaTeX using TeXnic Centre, am I'm having trouble with figures. It seems to only let me have one image per page, and just bumps all the rest of the figures to the end of the pdf. Is there a command to let it squeeze more figures on each page? Thanks Aaadddaaammm 03:44, 7 September 2007 (UTC)[reply]

Objects that can move like that are called "floats" in LaTeX; here is a discussion about changing the rules about their use. You can also not use the picture environment, which creates the float; if you just include the graphics directly, it'll be in-line with the text as if it were a letter. The downside to that is that it can no longer get an automatically-formatted caption and doesn't participate in the references-to-figures system (making Figure 2 an inline will make Figure 3 be known as Figure 2 unless you modify the counters yourself, and there will be no way to use \ref to get a reference to the original Figure 2). --Tardis 15:15, 7 September 2007 (UTC)[reply]

Font sizes in Excel

I have a number of Excel spreadsheets, all with similar text in them. I have formatted the text in one particular cell of each spreadsheet to 24pt Arial. But when I print the spreadsheets, this text is bigger on some sheets than on others. Does anyone know why this should be? My guess is that it is something to do with scaling - under Page Setup, I have selected the Fit To option - but beyond that I have no clue. Many thanks. --Richardrj ^talk ^email 07:25, 7 September 2007 (UTC)[reply]

If you use "Fit To" then Excel adjusts the size of the printout accordingly, and font sizes change in proportion. So if the sheet is shrunk by 50% to fit the number of pages you specify, text that is 24pt in the original will be printed as 12pt. AndrewWTaylor 07:33, 7 September 2007 (UTC)[reply]

Color in Excel

Hi all:

I have an excel file with a grid that has different numbers in each cell. I would like to visualize the patterns better, and I was wondering if there is any way to program Excel to choose a background (or font) color for the cell based on the value of the number in that cell. For example, I would like the small numbers to be black, and larger numbers to be white (with shades of gray in between)... Thanks! --Waldsen 11:42, 7 September 2007 (UTC)[reply]

In excel2000 (not sure how other versions are similar), Select the cells that you want to apply the formatting to and go to Format --> Conditional Formatting.., that should open a dialog that you can set whatever constraints you want and get it to format the cells based on the conditions you set. You should be able to set a condition for each shade you want to get the effect you describe. Hope that works for you :) Capuchin 11:58, 7 September 2007 (UTC)[reply]

Excel 2003 is the same. One limitation is that you can only apply 3 conditions, but you can add a fourth by pre-formatting the text. For example, if you want x<10 red, 10<=x<20 yellow, 20<=x<30 green, and 30<=x<40 blue, you can manually format all the text red, then make conditional formatting for the other 3 situations, which would override the red for x of 10 & up. jeffjon 20:24, 7 September 2007 (UTC)[reply]

You could write a macro that sets the colour rather easily. I forget the syntax exactly but it would be something along the lines of assessing the box's value and then setting the cell shading to be whatever you desire. ny156uk 22:57, 7 September 2007 (UTC)[reply]

I paste below an excerpt from my sudoku solver written in excel basic (If anyone wants it, I could provide the entire thing):

What you refer to is nothing more than prefilling a form. You may be thinking about registering variables though. This is a weakness in scripting languages that allow it.

.xnk (Outlook)

Microsoft Outlook allows me to create a shortcut to an Outlook entity (e.g., a folder in Public Folders); this has a .xnk extension. With Windos XP and Office 2003, I could double-click to open it.

Weird Image

When a wiki has an external link like this there is a little image of a box with an arrow coming out of it. Also when you link to an mp3 file like this there is a little speaker next to it. Does anyone know what those images are called and where they are located?

Wikiman232 18:34, 7 September 2007 (UTC)[reply]

Called? Background images. Really. They're placed there by the [CSS] and it's done with selectors; for example

#bodyContent a[href ^="https://"],

.link-https {

background: url(lock_icon.gif) center right no-repeat;

padding-right: 16px;

}

will apply that background to every HTTPS link, with enough padding on the right so no text overruns it. --Blowdart 19:20, 7 September 2007 (UTC)[reply]

The code to make that magic happen is at http://en.wikipedia.org/skins-1.5/monobook/main.css?97 , and the images themselves are at http://en.wikipedia.org/skins-1.5/monobook/external.png and http://en.wikipedia.org/skins-1.5/monobook/audio.png . --Sean 19:24, 7 September 2007 (UTC)[reply]

Slow down animations

I use MSIE7 in WinXP. Is there a way to slow down animations such as to, say, 1/10th the speed? -- SGBailey 08:34, 8 September 2007 (UTC)[reply]

Yes, but it will take GIF editing software. Basically what you want to do is to increase the amount of time per frame by 10X. I would use Adobe ImageReady for that but I'm sure there is also a free way to do it. --24.147.86.187 12:31, 8 September 2007 (UTC)[reply]

Oh — do you mean, "is it possible for me to have GIF animations play slower in my browser?" If so, the answer is probably no, unless there is some sort of outrageously clever Firefox addition that takes care of it. --24.147.86.187 13:27, 8 September 2007 (UTC)[reply]

1) Game consoles are, essentially, specialized computers. 2) Depends on the console.

Processors just run program instructions. Games are just types of programs. Consoles are just computers made to do one specific task (play gmes). --24.147.86.187 17:01, 8 September 2007 (UTC)[reply]

Are you asking why game companies don't just write games for general-purpose computers? One reason is homogeneity. All the consoles of a certain type have exactly the same computational hardware, so they don't have to worry about dealing with different vendors' buggy drivers and providing a low-detail mode for low-end computers and so on, which saves development time. Another reason is intellectual property. Console vendors like proprietary systems because they can charge royalties on every game sold, and game companies like proprietary systems because they make piracy harder. -- BenRG 23:42, 8 September 2007 (UTC)[reply]

Nintendo’s Wii costs US$250 and comes with a game: Wii Sports. New games for the Wii generally cost US$50 each.

Sony’s PlayStation 3 60GB version costs US$500 and comes with no games, the 80GB PS3 costs US$600 and comes with a game: Motorstorm. New games for the PS3 generally cost US$60 each.

Microsoft's Xbox 360's three versions cost US$279, $349, and $429 respectively. None of them come with a game. New games for the Xbox 360 generally cost US$60 each.

Sony’s PlayStation 2 costs US$130 and does not come with a game. New games for the PlayStation 2 generally cost US$30 -$40 each.

Microsoft’s Xbox and Nintendo’s GameCube are no longer in production and the prices of the consoles vary widely if you can find them at all. New games for these consoles are rare, but games for them are generally priced similar to, or slightly lower than the PS2’s games.

Hope that helps. 69.205.180.123 00:03, 9 September 2007 (UTC)[reply]

I hate the idea of game consoles (these people are still living in the pre-Amiga days..) but I'll admit one major advantage to them is the lack of operating system overhead. You do have to have a pretty good API to outperform directx and the like, even if you're running on a dedicated system, but theoretically you can get much better performance by trusting the game software and totally forgoing memory protection and other performance-draining features necessary to a real OS. I won't go into how undesirable it is to own a non-programmable computer or the ethics of signing "licensed" games and similar DRM (it's wrong.). --⁪froth^t 22:18, 10 September 2007 (UTC)[reply]

I use syndaemon(1) in Linux to disable the touchpad while typing. Assuming you have the synaptics touchpad driver (it's pretty ubiquitous), you should already have syndaemon; check out its man page. If you want to disable the touchpad completely (all the time, not just while typing), there seems to be an option value of the synaptics driver which you can stick in the relevant InputDevice section (look for 'Driver "synaptics"') of your xorg.conf:

       TouchpadOff (Integer)
              Switch off the touchpad.  Valid values are:

              0   Touchpad is enabled
              1   Touchpad is switched off
              2   Only tapping and scrolling is switched off

A good heap of further information is on the synaptics(5) man page, so take a look. -- Daverocks (talk) 13:00, 11 September 2007 (UTC)[reply]

Microsoft Excel question, probably a dumb one

I have a Microsoft Excel spreadsheet, it's not for math or formulas, just to keep notes on something. Many of the cells have a lot of text in them (up to a paragraph) but I don't want all the text to be visible in the spreadsheet, as long as I can see it when I click on that cell. Does that make sense? This usually works fine, but occasionally Excel will automatically resize the cell for me, making the entire row taller so that I can see all the text in that row at once. I don't want this; it is annoying and frustrating that I don't know why it sometimes does it or how to fix it. I know that I can change it back by going to the Format menu and selecting Row and manually adjusting the height, but is there an easier way? Instead of fixing it like that each time, I'd rather just know why it's doing that so I can avoid the problem. Thanks in advance for any help you can give. --Grace 01:24, 9 September 2007 (UTC)[reply]

It's really hard to tell since we have no idea what you're doing with the spreadsheet. But there are several easier ways: Try selecting the cell, the column the whole sheet, or whatever you want to be displayed in this way and hit Ctrl+1 (the number one). This will give you the Format Cells dialog. In the Alignment tab, either unselect Wrap text or select Shrink to fit, whichever you like better. — Sebastian 09:17, 9 September 2007 (UTC)[reply]

Running a game in windowed mode

Hi, I have a game that I would like to run in windowed mode. None of the configuration files I have come upon so far seem to allow such an option to be turned on. The target is "C:\...\RomeTW-BI.exe", do I need to add anything to this to force it to run windowed? Thanks in advance. :)) 81.93.102.185 11:43, 9 September 2007 (UTC)[reply]

Some programs allow it, some don't. First see if the game has the option to run windowed mode through any of its in-game options. If not, go to the shortcut of the game (or create one) and try changing the target to have a " -window" (with a space) or " -w" and running the game - the two most common switches for windowed mode. Otherwise, you'd have to run an emulator or a sandboxing software that runs in a window to force it to be in a window - but that is often more trouble than it's worth. x42bn6 Talk Mess 12:40, 9 September 2007 (UTC)[reply]

Difference between Mirroring, Failover, Clustering and Load balancing?

What is the difference between Disk mirroring, Failover, High-availability clusters (a.k.a. Clustering?) and Load balancing?

It would seem that Load balancing is different in that it involves a server that redirects traffic to an array of servers which then handle the traffic from there, and each of the servers in the array may be slightly different.

Mirroring / Failover / HA Clusters seems to be multiple servers that [may or may not?] have identical disk images that each act as a backup ready-to-go in case the primary server failed.

Perhaps Mirroring / Failover / HA Clusters may not actually have identical drive contents? Maybe they are all server data in unison, just without another server acting as a Load Balancer?

Help?

--Eptin 22:09, 9 September 2007 (UTC)[reply]

That's a lot of questions. Did you check into each of the articles you linked? Keep in mind that many of these look and act the same. Or, you may use multiples of them at the same time. That is, if you have a number of web servers fronted by a load balancer, you could call that a high-availability cluster of load-balanced servers, exhibiting failover. If a web server fails, the load balancer fails over to the remaining ones. There is a cluster of them, and when they are not in a failure state, you can balance the load across them.

Mirroring, in my mind, just means that you've got two identical drives, and you always write the same thing to each. If one drive fails, you still have the other drive -- you can fail over to it. --Mdwyer 04:06, 10 September 2007 (UTC)[reply]

Smells like homework; however; disk mirroring is generally on a single machine (setting aside remote mirroring provided by SAN clusters.) failover is when you have a hot standby machine, with the master writing data to a shared drive (NAS or SAN) and is brought up after the master fails, load balancing is where two or more machines run at the same time and requests to them are split between machines (with the machines synchronising between themselves if the requests actually change things), high-availability clustering is a combination of load-balancing and failover (where, because two or more machines are running at the same time there is no delay in failover as would happen with non-clustered failover, and data is synced between the machines if they don't share storage). However a lot of the time they're used interchangeably in marketing materials. --Blowdart 05:51, 10 September 2007 (UTC)[reply]

Bots

Hi, I know about four programming languages, and I know how to put a bot up for approval etc, but what I was wondering was, what do most people find as the most user friendly interface for building a bot, like PASCAL or Python. Thanks! Yamakiri 22:45, 9 September 2007 (UTC)[reply]

First, you have to define "bot". There are many definitions of that term in Computer Science alone. -- kainaw™ 00:55, 10 September 2007 (UTC)[reply]

It sounds like the question is in reference to bots on Wikipedia. It doesn't really matter what you develop the bot in; so long as it is compliant with the standards (i.e. it can be deactivated by an admin if it malfunctions, etc). You might consider a technology that allows for easy standard data interchange, such as XML. What are you trying to do? That will help narrow down the "preferred" technology choices. See Wikipedia:Creating a bot for details and tools! Nimur 01:34, 10 September 2007 (UTC)[reply]

I think the reason most people use Python, anyway, is because there are already classes written in Python to help you interact with the Wiki. That is, you can skip pretty much to the "what should the bot do?" phase rather than worrying about the "how does the bot connect to the internet? how does it log in? how does it differentiate the content? how does it search?" etc. sorts of things. I could be wrong on this, though. --24.147.86.187 01:49, 10 September 2007 (UTC)[reply]

Since MediaWiki is written in PHP, I'd be rather surprised if there aren't already premade libraries for PHP as well. -- kainaw™ 01:53, 10 September 2007 (UTC)[reply]

It wouldn't help things that MediaWiki is written in PHP, since you wouldn't be interacting with its code directly—just its HTTP outputs/inputs. While I find PHP a pleasant scripting language, it is not generally used for things like bots because it does not lend itself to being run endlessly (most PHP scripts have very quick execute times are normally set up to automatically exit if they take more than a few seconds to execute). While you can make PHP iterate over a set of instructions again and again (or run it from command line interface), this is not really what it is good at and not really what it is designed for, and there is no real advantage to using it for such a thing in any case. --24.147.86.187 07:38, 10 September 2007 (UTC)[reply]

Oh, that's good then thanks! Didn't think about the PHP part though. Yamakiri 10:54, 10 September 2007 (UTC)[reply]

Laptop AC Adapter Problems

A few hours ago, as my Dell Inspiron e1505 laptop was running off of the AC adapter, the adapter suddenly stopped working - the battery icon indicated that there was no adapter power and the adapter's green status light had turned off. I unplugged the adapter and replugged it into several different sockets, and after some tries, the light turned on again.

Just now, I had the same problem, and "fixed" it by the same method. However, as soon as I plugged the adapter into the computer, the green status light ceased. It is now broken for good as far as I can tell.

I was just going to buy a new adapter, but when I asked my friend about this, he said that he had the same problem himself twice (i.e., the status light turned off as he plugged it into his Dell laptop), and both times his computer stopped working and had to be sent for repairs. Both times customer service fixed it and told him that his motherboard had been fried.

Thus, my question is: Is this a problem of my adapter (in which case I should just get a new one), or is this a problem of my computer's motherboard or whatever (in which case I should be more worried)?

Thanks, -MagneticFlux 03:03, 10 September 2007 (UTC)[reply]

Why we have asked to enter the verification code, while creating E-mail? —Preceding unsigned comment added by 61.247.255.10 (talk) 12:39, 10 September 2007 (UTC)[reply]

Can you be a bit more specific? Creating e-mail where? You may be talking about a CAPTCHA; they're used by some webmail providers to make sure it's a human creating the account. Computers can't read the text in the CAPTCHA image so they can't create an account. If computers were able to create accounts without the help of humans they could create large numbers of accounts automatically and use those accounts to send spam. — Matt Eason ^{(Talk  Contribs)} 13:13, 10 September 2007 (UTC)[reply]

Note that while computers have difficulty reading CAPTCHAs (I wouldn't put it past a bot able to use an OCR program or algorithm to read the letters, although it is difficult - note the noise and patterns), the hash associated with the CAPTCHA can be cracked. So, in other words, it doesn't solve everything but it certainly stops the most basic scripts - ones that can be written with a few minutes of thought and AutoIT, for example. x42bn6 Talk Mess 16:55, 11 September 2007 (UTC)[reply]

Vista and Ram

Hello, can anyone please tell me the maximum amount of DDR2 RAM windows vista will allow you to use without upgrading to 64bit? thanks. —Preceding unsigned comment added by 84.68.12.32 (talk) 18:41, 10 September 2007 (UTC)[reply]

This site says 4GB. This one agrees. The operating system shouldn't care about DDR2, that would be a consideration for the motherboard. --LarryMac | Talk 18:51, 10 September 2007 (UTC)[reply]

Or try...http://www.vistaclues.com/reader-question-maximum-memory-in-32-bit-windows-vista/ Not sure from a quick read over it what the answer is - but seems to suggest that with 4gb installed you'll not be able to utilise it all effectively. All very confusing unfortunately. ny156uk 18:52, 10 September 2007 (UTC)[reply]

Well, the short version is that a 32-bit processor has a limited number of addresses, and everything must have an address. That is, those addresses are used for both memory AND for communicating with devices. So, even if you fill the entire address space with memory, some of it will still be occluded by other things in the system. This is still a problem with 64-bit addressing, but the system area is unrealisticly far away. --Mdwyer 20:40, 10 September 2007 (UTC)[reply]

Two firefoxes, one profile

I have Firefox portable on my flash drive, as well as the Mac Firefox. I would like to set it up so that the profile for each is the same. Is there some way I can redirect the windows Firefox to use the mac's profile, or vice versa?

Thanks in advance, --Omnipotence407 21:21, 10 September 2007 (UTC)[reply]

If you have IRC, irc://irc.mozilla.org/firefox might help. --h2g2bob (talk) 00:18, 11 September 2007 (UTC)[reply]

Nope, I don't have IRC, if you could summarize or something, that would be great. --74.37.228.44 00:21, 11 September 2007 (UTC)[reply]

The profile is stored as a load of files in a folder. I don't think you can change which folder it uses - it will always place them on the hard drive (although you can make the folder a symlink in OSX).

However, you can copy the contents of the folder by hand. I don't know of any way to make this automatic.

Some files can have information on locations of files on the disk (for example, if you set .ram files to always open with realplayer). This will change between OSs and may cause problems.

You should be able to copy your bookmarks (bookmarks.html) between profiles without any problems (until Firefox 3 is released). There's some firefox extensions which put bookmarks online for sharing between different computers - [4][5] - which would do this for you.

Hope this helps somewhat - take a look through http://kb.mozillazine.org/ for more info, and you should backup before doing anything risky. --h2g2bob (talk) 00:49, 11 September 2007 (UTC)[reply]

I think it's possible between Windows and Mac. I did it between Ubuntu and Windows once, and it worked fairly well. Some very complex plugins/add-ons might not work, but ones like AdBlock do. Basically, run firefox.exe (and/or thunderbird.exe) using the "-profilemanager" option. That allows you to change where the profile points to on the drive. So just set them both up to point to the same directory. But backing up your data first would definitely be a first step. --Bennybp 02:20, 11 September 2007 (UTC)[reply]

Computer Rebooting

I have a computer with Fedora on it that keeps rebooting randomly. It is not rebooting when a specific device is used, a specific program is run, or after a specific amount of time. I strongly suspect the memory is bad, but I was wondering if there are any Linux utilities that can keep a very close eye on the entire system and give me a good analysis of what happens just before each reboot. -- kainaw™ 00:44, 11 September 2007 (UTC)[reply]

One linux utility is strace. You use -p with pid number to indicate what you want to trace. It records all the system calls. using the -f option will also record all the child processes. It would be best to put the output to a file with -o option, and then try to read the file after a failure. The next step up is to use a debugger, though I expect there will already be too much output. It may be better if you can get hold of a memory tester. I havent seen one of these for at least 12 years, but they should still exist! Graeme Bartlett 04:38, 11 September 2007 (UTC)[reply]

strace only traces syscalls of a particular process, and won't help much here. I suggest checking the syslogs to see if anything is logged before it reboots. You might want to set up syslog to log to a remote host, in case the disk drivers crash before it reboots. In the end, you're going to want to test the hardware -- if you suspect bad memory, I suggest using the memtest86 memory testing tool. -- JSBillings 10:50, 11 September 2007 (UTC)[reply]

Log files reported nothing. Memtest86 ran all night - no help. No reboot though, so it isn't something inherently bad in the power supply (or power source from the wall). Ran with ide=nodma, still rebooted. I'm going to open it up and look for a loose cable. -- kainaw™ 12:20, 11 September 2007 (UTC)[reply]

I've had similar problems after i reseated the heatsink on the cpu, it could be overheating. If you have acpi setup you might be able to look at the cpu temp somewhere in /proc/acpi/. I solved my issue by cleaning the heatsink and using new heat-conductive paste. -- Diletante 14:54, 11 September 2007 (UTC)[reply]

I've seen this happen with systems that had a lot of "noise" in their power, or irregular power dips. Most electronic appliances work just fine with these problems, but computers are overly sensitive to irregularities in power. Also, if you suspect it is your CPU, try monitoring the temperature of your CPU. -- JSBillings 20:44, 11 September 2007 (UTC)[reply]

After memtest86 claimed the memory was OK, I checked further. Nothing in logs. Swapped out a lot of components. Finally, I believe I tracked it down. The CPU fan appears to be flaking out - just stopping every now and then. The BIOS doesn't provide monitoring of the fan to the OS, so it wasn't logged. I found out by having the case open and examining the inside while it was running. The fan just stopped. I tapped it and it started back up again. A few minutes later, it stopped again. Hopefully that's the source of this and I won't have to poke around this case anymore. -- kainaw™ 22:16, 11 September 2007 (UTC)[reply]

Add a string of text to the end of every line of a text file.

Is there any options on a Windows application, that will find the end of every line (newline) and append a string of text to it. I know on with the Linux application VI (VIM) you can add text to the end of every line with the character "\n" representing a newline. I can't remember if this used a find and replace command, I just looked up the command and copied it. I was wondering if anyone knew a windows app that will do this. Preferably I use edit.exe a.k.a edit.com but if notepad, wordpad, or Microsoft Word had an option like this? – 69.150.209.13 01:57, 11 September 2007 (UTC)[reply]

On Windows, I'd recommend Notepad++ for an advanced text editor. You can use the replace function with regexps by pressing CTRL+R. — Kieff | Talk 04:11, 11 September 2007 (UTC)[reply]

Using ADBLOCK to remove a specific wikipedia link.
Hello, as I try to revert as much vandalism as possible in the shortest amount of time, I often mistakenly click the stupid 'Edit summary' link when one goes to edit the page, instead of clicking "Save Page" button.

Removing Windows Media Center
I play a lot of DVDs on my computer, for which I use Windows Media Player. Whenever I put in a DVD, Windows (in its infinite wisdom) automatically starts Windows Media Center, which I despise and have absolutely no use for.

Regex in Java: finding expression 1, but not if it's part of expression 2
Hi all,
I'm having trouble writing a regular expression in Java. I want to find all instances of the string cde, but NOT if it's part of the string abcdefg.
So if I gave my parser the text abcdefgcdex, it should only find this "cde": abcdefgcdex.
Is that possible? I'm really not sure how to go about creating such an expression.

Any help much appreciated!
Thanks, Mary. 16:45, 11 September 2007 (UTC)
You can be verbose to make it very understandable. For example, simplify it to "cde" as long as it doesn't follow "ab" (you should easily how this can be expanded to check for following "fg"): (cde.*)|(.cde.*)|(.*[^a][^b]cde.*). In other words, if "cde" has nothing in front of it, that is fine. If it only has one character in front of it, that is fine. If it has two or more characters in front of it, they better not be "a" followed by "b". -- kainaw™ 17:38, 11 September 2007 (UTC)[reply]
How about something like this:

(?<!ab)cde|cde(?!fg)

"cde" as long as it's not preceded by "ab" or not followed by "fg". --Spoon! 17:54, 11 September 2007 (UTC)[reply]
Hi Spoon,

That works great, thanks! However, I'd like to be able to put a regex within the "(?<!ab)" section -- let's say an a followed by any number of b's. I would think that I should be able to say "(?<!ab*)" or "(?<!a(b)*)" or something, but I get an exception. Do you know what I could do?

Thanks!

Sam
Sorry. As far as I know lookahead assertions can take any regex; but lookbehind assertions can only take a fixed-width regex (because otherwise it is difficult to figure out where to start). --Spoon! 22:37, 11 September 2007 (UTC)[reply]
