Video card artifacts examples
Drawing errors made by video cards are refered to as visual artifacts. These artifacts can be caused both by software and hardware problems. If you see artifacts during the power-up screens before your operating system loads then you know it has nothing to do with drivers. There are any loaded yet. If you’re seeing visual artifacts in just one program then it may be a software problem with that program. But if you have artifacts in many programs then you may have a driver problem or bad hardware. If you’re seeing artifacts only after the operating system loads then the first thing you should do is the standard “update your drivers” drill: update your motherboard chipset drivers, and uninstall your display drivers and then reinstall the latest display drivers. Updating your drivers can sometimes fix your problems and you should always do this even if you think that your hardware is responsible. You should exhaust the easy software solutions before guessing that you have bad hardware.
It’s also a good idea to open up your computer and make sure all the fans are working. Overheating is a common cause of artifacts so you should check that any fan on your video card is rotating. The temperature of your video card depends on what kind of program you are running. Most video cards are relatively cool when you are running 2D programs. The temperature of the video card increases when running 3D programs like games. If your artifacts only show up after a few minutes of playing games then overheating is usually the cause. The silicon chips on your video card run slower at higher temperatures. The hotter the chips get the more trouble they have keeping up at their standard clock rates. You can prove that it’s an overheating problem by running your computer with the case open and aiming a desk fan at the video card. If the artifacts go away then you know that you have an overheating problem.
Another thing you can try to reduce artifacts is to underclock your video card. Underclocking reduces the clock rates of your GPU or video RAM. Reducing clock rates lowers the temperature of the chips and often allows weak ones to work properly. There are instructions on how to underclock your video card on this page. And if you’re overclocking your video card then you should back off on your overclock. Overclocking often causes artifacts. Excessive overclocks can raise the temperature enough to cause cumulative damage. The overclock may work properly at first and then artifacts only start showing up weeks or months later after the chips have been sufficiently damaged.
A lot of hardware must be functioning properly to generate images correctly but there are three main sources of problems: the video RAM on your video card, the GPU which is the main chip on the video card which does the drawing, and the bus interface which transfers data between your video card and your motherboard. You can often get an idea of which is causing the problem by looking carefully at the artifacts.
If your artifacts are covering the entire screen and involve color shifts or slight position shifts, then the problem may be caused by your monitor. If you have another monitor available then you should try it out to see if that’s the problem. If you don’t have another monitor then you can take screenshots of the screen. To do that press the Print Screen key and then go into an image editing program (like Windows Paint) and paste the clipboard to an image. You can also use free programs like Fraps to write screenshots directly to a file. If the screenshot looks fine on another computer but the screen looked bad on your monitor then the problem could either be a problem with your monitor or with the video output circuitry of your video card. Most of the time it’s the monitor rather than the video output circuitry.
And how to keep the neighbours from stealing yours.
When I moved into a new neighborhood, I expected the usual hassles. Then I found out I’d have to wait more than a month for a DSL line. I started convulsing. . So, what was I supposed to do? There’s an Internet café on the next street, but they close early. I had no choice—it was time to start sneaking on to my neighbors’ home networks.
Every techie I know says that you shouldn’t use other people’s networks without permission. Every techie I know does it anyway. If you’re going to steal—no, let’s say borrow—your neighbor’s Wi-Fi access, you might as well do it right. Step one: Lose the guilt. The FCC told me that they don’t know of any laws that make it illegal to log on to an open network. Using someone’s connection to check your e-mail isn’t like hacking into their bank account. It’s more like you’re borrowing a cup of sugar. (Unless you hog their bandwidth by watching lots of streaming video—that’s like hijacking a sugar truck.)
In the end, it’s your neighbor’s Internet service provider—not your neighbor—who will pay for the added traffic, and the ISP has already factored a small amount of line-sharing into their price plan. It is true that your surfing could cause the folks next door to break their service contract—many broadband providers do specifically forbid home customers from sharing a connection. But let’s deal with those abstract ethical issues later—you have important mail to answer!
Twice a year, independent antivirus testing lab AV-Comparatives.org releases a report comparing how well 15 to 20 antivirus products can detect malware in an on-demand scan. In the latest report, quite a few products improved their ratings, though a couple cloud-based tools failed to complete the test. AV-Comparatives also offers new insight into the problem of false positives.
Many Improved Ratings
Every product that passes the on-demand scan test rates at least STANDARD. Those that do a bit better than the rest rate ADVANCED, and the very best products rate ADVANCED+. If a product doesn’t pass, it receives the rating TESTED.
Four products that rated ADVANCED in February’s test moved up to ADVANCED+. They are: avast! Free version 6.0, ESET NOD32 Antivirus 5, G Data AntiVirus 2012, and Panda Cloud Anti-Virus 1.5.
AVG Anti-Virus Free 2012 moved up from STANDARD to ADVANCED, and Trend Micro Titanium Antivirus+ 2012 leapt all the way from STANDARD to ADVANCED+.
A Few Going Down
A few products slipped in the ratings. TrustPort Antivirus 2012 and eScan Anti-Virus 11 slipped from ADVANCED+ down to ADVANCED. PC Tools Spyware Doctor with AV 8.0 didn’t pass this time, going from STANDARD to merely TESTED.
python script will display the track you are currently listening to via clementine in xchat when u type /np command
Ethan Best wrote the script originally kudos to him
Script Was Modified By a good friend @corndogcomputer to show “HD Audio Output current track by current artist” opposed to the original script which showed “np current track”

I came across a now playing script for xchat/audacious (python) get it. Here
also here is a working perl xchat script for XMMS now playing+ Here
The technological world is split into two separate but inexorably-linked worlds: hardware and software. In fact, almost everything in life has a hard, physical manifestation, and a soft, less-tangible control system counterpart. Cars, and on-board controllers. Computers, and operating systems. Human physiology, and brains. The fact is, hardware without software is meaningless, and likewise, a piece of hardware — a tool, a device, a weapon — is only as powerful as the software that controls it.
One day, computers will be so small that you’ll be be stitched into your clothing, or perhaps wired straight into your brainstem. If you’re on the move, you’ll use some kind of head-up display that’s projected onto your eyeballs (or a direct input into your visual cortex), and when you’re in the office you might jack into a large display. This is all hardware, and without the necessary software this sci-fi future will never come to pass.
Fortunately, the software already exists, and better yet: almost every computer user and web surfer already uses it. I am talking about single sign-on; a single name and password that logs you into multiple services. Facebook Connect, Windows Live ID, and even Mozilla’s upcoming Browser ID are prime examples of single sign-on.
