Is it possible to reconstruct the original file from an md5 hash? I don't really completely understand how md5 works, only that it gives a unique id to every file and can be used to verify files. Is it a two way process? Thanks!-- Ryan 00:00, 25 February 2007 (UTC)
What are some other websites like Google Answers? Also, do any researchers have their own service?
I use a flash drive to store files from Quick Books. The last time I updated my files I was able to save to the flash drive without any problems. When I try to access my files today, I am getting this error "Quickbooks was unable to create the image file. The disk could be full or you may not have sufficient rights to the data directory.".
I am able to use a different flash drive that has other QuickBooks files on the same computer without any problems. I also tried using the corrupted flash drive on a different computer and I receive the same error. So, I have to think it is a problem with the flash drive itself, and not the computer.
Is my flash drive corrupt? Is there something I can do to fix it without losing the data stored on the drive?
Thanks!
Not sure if this is the problem in your case, but the weight of a pen drive can cause it to "sag" and lose connection. This usually shows up as no flash drive listed as attached. You can test for this by supporting it's weight with your hand (holding it completely horizontal). If this fixes the problem, then the permanent solution is to get a short USB connection cable which will allow the flash drive to rest on the table without putting strain on the connection.

I scanned a painting (reproduced at a pretty small scale) from a book at 400 DPI, and it's come out with this repeating halftone pattern on it. Is there any way to deal with that? Using a "despeckle" filter gets rid of the detail and makes it look mushy. I have a lot of paintings to scan from this book, so any sort of specialty tool would be much appreciated. grendel| khan 03:30, 25 February 2007 (UTC)
I heard the Google will professionally search for a keyword that you choose, but, it costs money. Does anyone know the name of the service? 68.193.147.179 03:49, 25 February 2007 (UTC)
I'm trying to compile a TeX file to PDF. Every time I open the PDF, at some point in the file it give me an error message "Too few operands in path", and shows a blank page. How could I solve this problem? deeptrivia ( talk) 04:55, 25 February 2007 (UTC)
I am rather stuck on a part of my program; I am trying to add another row within a JTable, however I can't get the component to update. I have already traced through the debugger (I am using Eclipse), and I am positive that the book is successfully added to the ArrayList, and I am positive the method that adds the data to the two dimensional array used for the data works (it displays initially). I have tried everything that comes to mind, but nothing works. The code that I am trying to use to update the JTable is as follows:
public static void redrawDataTable() { //jtblData = null; jtblData = new JTable(setJTableData(),colNames); JScrollPane jscrpane = new JScrollPane(jtblData); disp.add(jscrpane); //jtblData.updateUI(); jtblData.repaint(); jtblData.setVisible(true); disp.setVisible(true); }
Since I don't think I (or anyone, for that matter) could debug code without seeing everything in context, I went ahead and put the classes from the Java program on the web here. Any assistance on this confusing conundrum would be greatly appreciated. Kyra ~(talk) 05:14, 25 February 2007 (UTC)

, it is by default added at the bottom of the
Z-order. So all your later additions are behind the first one you put in! Of course, the real solution (as grendelkhan provided) is unrelated to this point, but I think the diagnosis is also interesting. --

03:46, 26 February 2007 (UTC)Recently, I downloaded some AVI files from the site www.thisisthusfl.com. Windows Media Player said I didn't have the codec for the files, so I downloaded some codec package from some website (forgot which). With the codecs installed, the AVI players would play, but some of my WMV and MPG started playing without sound. I uninstalled the codec package, but the files still played without sound. I tried upgrading to Media Player 11, but that did not help. Strangely, one of the files plays with sound in RealPlayer but not with Windows Media Player, while some files play with sound in neither and some with sound in both. Any idea what is going on? -- Mwalcoff 08:04, 25 February 2007 (UTC)
How powerful is this graphics card? Specifically, I would like to know technical specifications like core clock speed, support or Pixel Shader 3, and so on. Thanks a lot!-- Ryan 20:03, 25 February 2007 (UTC)
I am looking to buy a really good computer system, any suggestions? 68.193.147.179 23:19, 25 February 2007 (UTC)

You can usually customize a high-end PC for a lot cheaper through smaller companies; my favorite has been CyberPower PC; my last 2 computers were through them, I'll be getting another one later this year from them, and a couple friends have also bought repeatedly from them. They offer more choices for customization than any other site I've seen. I'm trying to customize a high-end video editing system (Q6600 quad-core processor, 2GB PC6400 DDR2/800 RAM, ATI X1950, WD740ADFD boot drive plus a large storage drive), and it comes out to about $2600 through them, while it's nearly $4000 through Dell and almost $5000 through Alienware. — BRIAN 0918 • 2007-02-26 18:54Z
I was wondering how to make a verticle template that appears on the righthand side of the article like {{ Disneyparkinfo}}. I know how to make a horizontal template that appears across the bottom like {{ Epcot attractions}}. Can you help me? WDWbuff 23:24, 25 February 2007 (UTC)
