I had Windows XP Pro on my computer, but my antivirus software killed my genuinizing software, and so XP expired and won't let me log on to my account. I installed corporate windows on my computer but cannot access any of my old files, including several very important photoshop paintings. Is there any way I could get those files without having to buy XP? Thank you SO much.

I have an array I've built of SATA drives and lots of those Sata Y-splitters for power to make it work. In the interest of cable management, I was wondering if anyone know of a single-line sata power connector available?



Basically, I have a bunch of these chained together with molex Y-connectors.



I'm looking for one that supports 6 or 8 or 10 devices like this in a chain:



Anyone have an ideas before I pay this custom cabling place a small fortune to make me a set?

Does anyone here have any experience with virtualization software- particularly Sun's VirtualBox? I'd like to start learning about virtualization, especially since I now have a machine which will handle it fairly easily.

I'm rather amused that I'll probably be using Sun's virtualization software because MS own Virtual PC won't run on Windows Vista Premium.

Imagine that!

...not that it would actually work, but it perhaps might stop someone from at least pandering it on Craig's (which nobody would be stupid enough to do, but...)

I posted a couple of days ago about bringing video from VHS and turning it into dvd. I realized I was trying to bring it in through a sVideo out port on my laptop. I have a sVideo port and a VGA port. Can I use either to brings video in sans a tv tuner card?

I have now made TickleText completely "themeable" (the user can change all colors, including window bg and text color, not just the font and text widget bg).
I have integrated TickleDict into the tools section.
I have made numerous other changes.
I have localized it to Brazilian Portuguese.
At the moment, only the PT_BR version with all updated functions is up at sourceforge, but,
I should have the English version up within the hour, really.

Here is a nifty screenshot of TickleText-PTBR:

Hello, I was opening my computer to clean out some of the accumulated dust and came across a problem while trying to put all the wires back together.

I connected everything as it need be, but noticed my hard drives weren't being read. After trial and error I noticed my IDE1 slot was the source of the problem( I got the hard drive to boot when I unplugged my DVD rom and used IDE2's hookup to relay hard drive info, previously when I tried it in IDE1, it would not boot up correctly)

Anyways, now I'm wondering if there is a way to fix this problem? Then I also thought, maybe it's time for an upgrade and wondered for what price could I get another mother board that would support my 256(512 total) ddr mem and my radeon 9200 -128mb video card?

I also thought, wow is my stuff really out of date and I wont be able to play many current and future games?

Answers to some of these questions and maybe a few recommendations are very appreciated.

I've got a problem. I've got a router running iptables with masquerading and NAT running. I want to block some IP ranges from coming into the system. However, it seems that no matter what I try, I can't actually block the IPs. Right now I watch the traffic going through the router to a web server on the other side of the router (but not on the router itself).

Here's the rules I'm trying (note I've tried every chain, INPUT, FORWARD, OUTPUT, PREROUTING):

eth0 is world facing, eth1 is internal

iptables -A PREROUTING -i eth0 -s 38.105.83.0/24 -j DROP
iptables -A PREROUTING -i eth0 -s 38.100.41.64/26 -j DROP
iptables -A PREROUTING -i eth0 -s 194.72.238.0/24 -j DROP
iptables -A PREROUTING -i eth0 -s 66.249.64.0/19 -j DROP


And here's a dump using iptables-save:

I have what may be a simple/stupid question for the networking/hardware people out there as I'm a software person for the most part. If I were to use a USB B male to cat-5 adaptor (which, despite my best efforts at the moment, I can't find) to plug my USB printer into my wireless home router, would I then be able to access the printer via an IP address? Thanks in advance!

I just downloaded and installed a program called "RegistryBooster 2". It said that I had well over 1300, yes 1300, assorted problems. I can clean 15 of them for free. I would need to purchase the full program in order to clean up the whole thing. Do you think this program is accurate in its findings? Is it worth it to spend $30 on it?

If it matters, I have WINXP Home and use Mozilla Firefox as my browser.

From searching the Ubuntu forums, it seems that a lot of other people are having this same problem. I bought my new motherboard (with onboard graphics) because several people told me that nVidia is excellent with Ubuntu, but this whole experience has seriously soured me on nVidia. My motherboard is an nforce 630i from XFX, and the onboard graphics card is an nVidia geforce 7100. I have nvidia-glx-new installed, after nvidia-glx didn't work - switching to nvidia-glx-new hasn't changed a thing, but it's what's still installed.

As seems to be the case with so many folks, X keeps starting in low graphics mode. It informs me that it couldn't properly detect my graphics card or screen, and gives me the option of manually configuring them. I do so, telling it to use the nvidia driver and that my monitor is 1024x768, and I click OK; it immediately decides to ignore what I've just told it and boots into 800x600, which it had started to do anyway. Going to System->Preferences->Screen Resolution shows me that it won't allow me to choose any resolution above 800x600; going to System->Administration->Screens and Graphics shows me that it's back using the vesa driver (which is the default in low graphics mode) and thinks I'm using a Plug n' Play monitor that only supports 800x600 resolution.

I have run dpkg-configure xserver-xorg more times than I can count and am sure everything is as it should be; no joy.

My xorg.conf, Xorg.0.log, and results from lsmod (remember I was in low graphics mode when I ran these - I don't know if that makes a difference) are available at http://ubuntuforums.org/showpost.php?p=4521613&postcount=10 .

I tried running dmesg and it scrolled so far that I couldn't see the beginning anymore. Should I post just as much as is left in my terminal?

Also, my sound isn't working either. Is that a function of low graphics mode for some reason, or am I going to have to troubleshoot that separately? At the moment I'm more concerned with sorting out the graphics, but the missing sound is an annoyance as well. Going to System->Preferences->Sound, selecting the Devices tab, and clicking any of the Test buttons gets me this error message:

audiotestsrc wave=sine freq=512 !
audioconvert ! audioresample !
gconfaudiosink: Could not open source for writing.

ETA: I tried Envy, and it told me that my video card is not compatible with any version of the driver. wtf?

ETA2: I found the appropriate driver version on nVidia's website and used Envy to manually install it. I've rebooted and all seems well now! Now to deal with the sound issue. Any help on that?

Thanks in advance for any help!

I have been wondering this for a while.  I have this card reader.  There are many other readers which have exactly the same case (though not by the same company).  An example is this reader. 
I'm wondering three things about this. 
1.  If the readers are the same and if so, what company makes them.
2.  There are other card readers out there (exactly the same look) which don't say explicitly that they are SDHC compliant.  So if they are the same, i'd like to know that way I can assume that that reader is also SDHC compliant. 
3. Where I can get drivers/downloads/details about this reader.

Thanks!

I fixed the touchpad and the security chip seems to be behaving (I tested the laptop Monday night by rebooting it and had no problems, so I've gone back to my regular routine with it). 

so disregard my last post here.  just wish I could delete it.  :/

and for those wondering how I fixed it, lots of beatings.  ;)
