I've come across many many projectors in our (national) company that don't display colours correctly. Without exception it is the red channel that seems to be broken. On Saturday I picked up the same phenomenon on another projector (different brand, different organisation completely). My google-fu is not strong enough to find a discussion about this on the web. What could be happening? Is it a known problem with the red channel on data projectors? AFAIK they are all DLP projectors rather than LCD. They are basically now unusable for movies or photos, only presentations. Even then you have to choose your colours carefully. The problem is so bad that we've been instructed to differentiate our graphs by some mean other than purely colour. The projectors are generally older than 1 year but <3 years. What the hell is going on? Zunaid 07:50, 22 July 2009 (UTC)
document.body.style.cursor = 'crosshair' (or one of the common cursors, like "hand" or "help") works, but changing "crosshair" to an image URL to get a custom cursor does not work! I also tried document.body.style.cursor = 'url(the_image_URL_here)'. I have checked many times and the image URL is correct. How do I get it to work? —Preceding unsigned comment added by 59.189.59.132 ( talk) 10:40, 22 July 2009 (UTC)
Thanks!!! How do I convert a bmp, jpeg or gif image to a cur image? Any other stumbling blocks to note?
Does anyone know an online collection of cursors which I can use with document.body.style.cursor? —Preceding unsigned comment added by 59.189.62.31 ( talk) 08:02, 23 July 2009 (UTC)
Hello. I'm looking for a tutorial on how to use the Ghostscript interpreter interactively. The only information I've been able to find is on how to run the gs command in batch mode. But I want to enter in PostScript one line at a time. I can't find a list of commands supported by Ghostscript and what the prompts mean (e.g., I often see a <1> or something similar after gs>). I found a very basic introduction with a hello-world example, but that's it so far. It just seems that no one is interested in PostScript any more. I don't understand why. Sigh.-- H.

how do i print screen WITH THE CURSOR?
Hello. I've had my laptop for two years and it's always worked fine. Recently though, every time I try to 'wake up' the computer from standby, I get a brief flash of blue screen of death, then the computer restarts. Otherwise, the computer is fine. I've checke dm power options, and they are set to default (I.e the power button is not set to instantly shutdown). Is there any way I can fix this problem? Many thanks in advance =) Cuban Cigar ( talk) 12:24, 22 July 2009 (UTC)
Check that the battery isn't running out. This can cause the "blue screen of death". Also, check when the computer is due to sleep in power options. 90.194.115.243 ( talk) 13:16, 22 July 2009 (UTC)
Ok my battery is always charged and is def not running out. In power options, system standby is set at 'never'. 114.77.68.9 ( talk) 13:53, 22 July 2009 (UTC)
It could be a ram issue if you are in sleep mode, could be a harddrive issue if you are in hibernation mode. In any case there is an issue with either hardware re-distributing the information stored within when your pc sleeps/hibernates

Is there an easier way to create a series of calender events than just creating them one by one using sunbird, windows calender or outlook? For example, could the events be created in an excel document and then converted to a .isc file and then imported? I know calenders can be exported into a .csv file from sunbird but I cant seem to import it back the way. I am using windows vista. 90.194.115.243 ( talk) 13:11, 22 July 2009 (UTC)
Hey everyone! I'm thinking about running a small website from my home computer. A few people, maybe about 20 or so in total, will connect to my server and view pages just like any other website. The problem is I have an awfully slow upload speed, approximately 40KB/s at best. Will this cause a big problem for people trying to use my site? Will it be too slow?
As a test I've set up an example of what my site will be like (edit: I've removed the link because I've turned the server off). If it's not too much to ask, could somebody test the features, like loading a few images, and report back on if it's too slow to be usable? I'm also interested in any advice, experience or really anything you can share with me about running a home server as I'm very new to this.
Thanks so much for your help! —Preceding unsigned comment added by 82.43.88.29 ( talk) 13:41, 22 July 2009 (UTC)
whenever I pull out a USB stick, I do not stop the device. Sometimes, I close the explorer windows showing folders inside the USB stick. I only see to it that the lights are not blinking or that I don't save or run anything from it when iam pulling it out. Will this damage the USB stick? —Preceding unsigned comment added by 131.220.46.25 ( talk) 15:01, 22 July 2009 (UTC)
If you want to pull the usb out quick (assuming you're on windows) makes sure you have (starting by selecting the usb stick or whatever in mycomputer) : Rightclick, properties, hardware, (select the device), then properties, policies, and select "optimise for quick removal" - that way if any copies are finished, you should be able to remove the device without having to use "safely remove hardware". I should have mentioned that. 83.100.250.79 ( talk) 02:33, 23 July 2009 (UTC)
Perl seems to have many nasty internal inconsistencies. For example, some functions affect its own argument(s) whiles many others don't.

Why did they create this obvious bug? -- Toytoy ( talk) 16:29, 22 July 2009 (UTC)
Personally, I find the basic syntax of functions not quite intuitive when they are nested. For example, you may want to paint your wall, so you ...
$painted_wall = apply(dip($brush, mix($paint, $water)), $wall);
The whole thing is very difficult to read (i.e., the reading direction is zigzagged). You can use more intermediate variables, but they make your code longer and more difficult to remember variable names.
$painted_wall = &apply(&dip($brush, &mix($paint, $water)), $wall);
I prefer to use the old-fashioned & prefix for functions. This prefix and the use of parenthesis is against the teaching of the animal-covered book Perl: The Best Practices. There is no way to do nested functions without enclosing the arguments in parenthesis unless you want to write your program in FORTH.

Forgive my ignorance and incompetence regarding this subject. I have a Creative SB Audigy 2 (WDM) soundcard. According to my Control Panel, this card apparently supports SPDIF out, which would be awesome because I'd like to connect it to my receiver for at least 5.1 surround sound. I pulled out my computer and checked the soundcard jacks, but I couldn't find any digital (optical or coaxial) output jacks :(. How do I get digital sound out to my receiver?

I have an iPod (clickwheel) whose internal database has gotten corrupted. It shows up as a USB drive, and I was able to (in Terminal) copy all the files off of it to my computer. The problem is, it doesn't show up in iTunes at all, so I can't "Restore" it.
Is there a way to Restore an iPod that iTunes doesn't recognizes? The iPod itself seems functional except that it doesn't remember that I have any music. The internal interface works fine, though.
I'm using a MacBook with OS X 10.4.11, with the latest version of iTunes (updated just a day or so ago), if that helps. Any suggestions? -- 98.217.14.211 ( talk) 17:43, 22 July 2009 (UTC)
OK, looks like we have a group of venerable referencedeskers, who seem to be able to answer any question one throws at them. I wonder if you folks could help me?
Here is my problem. There is a closed online system that I need to access (yeah, I have access rights, no worries there). The system is basically run via a cgi script--a user is presented with a form in a browser, fills it out, hits submit, and gets the results. Unfortunately, the system's interface gets tweaked every now and then. What this means, is that on some days some parts of the interface are different from what they used to be on the day before (and these are not visible changes; just changes to how the system works beneath). In most cases, clearing browser's cache is all that needs to be done, but on some truly sad days that does not work. The reason it does not work is because some of the js, css, and htm files get cached on the proxy server (to which I do not have access). Instead of getting these parts from the system upon request, the smart-ass proxy decides to serve the files previously cached. Yeah, the files have the same names, but the content is slightly different, which means that on my end the parts don't assemble well, which leads to all kinds of nasty errors.
So, the question--in a situation like this, is there a way to tell the proxy to go funk itself never cache anything from that website? If it were just a regular html page, one could add "?whatever=anything" at the end of the URI; unfortunately, since this is a cgi call, adding random crap like this at the end of the URI means that the request won't be processed because of "unknown parameters".
The problem appears only on the PCs which are all hooked through the same proxy. When accessing the system from home, I never have this kind of problems (which, for one, says that my ISP's proxy server is configured much better than the one at work).
I searched the web for several days now, and the closest I could find was this, which isn't exactly helping. Can this even be done (please say yes)?--Anonymous and desperate in the Midwest

I was editing an extremely long article, one that has been tagged so it can be split.
I tried to go back to what I was doing before I did that and the back button was no longer blue.
