How to block Web tracking

Web-tracking-illustration

When you’re on the Internet, there are good reasons to have that eerie sense of being followed. And don’t think you have anonymity just because your service provider gives you a dynamic IP address. At a minimum, visited websites can tell what service provider you’re with and what city or region you are in.

What’s more, any communication with a Web server gives it the opportunity to deposit a cookie on your computer. Benign cookies — small text files downloaded through your browser — simply record information needed to make your Web experience better. That can include sign-in information, where you visited on the site, interface customizations, and the like. Most cookies also keep an identifier for each visitor, so that the next time you connect to a site’s server, it can match you up with its records of previous visits. That way, you won’t have to start from scratch whenever you go to the site.(…..read the whole story)

Windows Media Center – Sleep Problem

Windows 7 Media CenterWakeup and sleep issues are common problems found in Windows Media Center (WMC), from XP to Windows 7 (perhaps Windows 8 as well).  This particular problem is about sleep. The media center PC does not go back to sleep after recording.

Further investigation reveals that the PC can go to sleep properly (according to the power management settings) without WMC running. Using the following shows the culprit, a USB audio device prevents the system from sleeping when WMC is open.

‘powercfg -requests’

The above command, executed under admin rights, states that “an audio stream is currently in use” associated with the USB audio device. I use the following to tell the system to ignore it and go on to sleep after the pre-set time has elapsed.

‘powercfg -requestsoverride driver “USB Audio Device” system’

Be careful when you copy the above command from a web browser and paste it directly on the CMD prompt because the blank space inside the name of the driver is not really a ‘space’ when pasted onto the CMD prompt window.

If you have a different device that is causing the problem, just replace “USB Audio Device” with the exact device name in your case. Click here to see a similar situation.

More Info (July 2014)

There is another driver ‘Legacy Kernel Caller’ that causes the sleep problem after a recent refresh of the Windows 7 system. Apparently this is from the driver of the TV tuner card (perhaps a different version from the previous installation). Just use a similar ‘requestsoverride’ described above and the sleep problem should be fixed.

Brother MFC Printers – ‘Unable to Clean’

Brother MFC-420CNWhen you see an error ‘Unable to Clean’ on a Brother MFC printer, the following solution may help resolve the problem without bringing it in for service.

1. Machine off
2. Switch on the machine while holding down the “menu” button until all the leds are flashing on/off. Now you are in “maintenance” mode
3. Press 80
4. Press the “mono start” button several times until you see “purge: xxxx”
5. Press “2783” in order to reset the purge counter. You will see: “purge:0000”
6. Press the “stop” button
7. Press “99” to exit the maintenance mode

If pressing “99” does not exit the maintenance mode, just unplug and plug the power cord back to restart the printer. This solution works on MFC-420CN; it may work on other models as well.

Temporary Internet Files

IEIt is getting harder and harder to locate the temporary internet files for each new version of Windows and Internet Explorer. Most people know that temporary files, created while browsing the internet, are stored under some hidden folders (or specifically called ‘Temporary Internet Files’), the parent folder path will differ depending on the version of Windows/IE.

Even if you can find ‘Temporary Internet Files’ after turning on the settings to show hidden files and protected system files, you won’t be able to see all temporary files. There are many ways to get around this but I’ve found one of the simplest ways is to copy the above-mentioned folder to another location. All ‘super hidden’ folders and files will then be revealed.

In case some files are locked by other open programs, preventing them to be copied, you may consider using some utilities such as ShadowCopy that will copy files even they are in use. (Note: the system at the discussion is running Windows 7 and Internet Explorer 9)

ISO to USB

(UPDATES 2013-07-07) There are problems when creating bootable USB drives and I’ve found a comparable utility that seems to be working better. Download the program from the following site:

HP Media Center IR Receiver

HP Media Center IR Transceiver HP Windows Media Center computers often come with a remote control and an Infrared receiver/transmitter. There are many version of this IR transceiver built for different versions of Windows. So if you use the remote in the version of Windows that it is intended for, you don’t need a special driver as it will already be included in the Windows installation.

But if you happen to have the following specific model but would like it to work in XP environment, you will need a special driver (download  here) for it. Be sure to identify the device as all versions of the transceiver look the same physically.

Model: OVU400102/71
P/N: 5187-4593

Repair a Pen Drive (USB Drive)

PenDrive-RepairIf you remove a USB drive while data are still being written to it, you may end up corrupting the drive and it becomes unusable. The device shows up as “XXXXXXXX U167CONTROLLER USB Device” in Device Manager when plugged in. The device LED light just blinks forever and Windows cannot recognize it properly as a mass storage device. If this happens to you, the following little utility may help you reclaim the drive (but not the data though).

If you are on Windows Vista, 7 or 8, set the compatibility mode to Windows XP SP2 and run as administrator.

Using Google Public DNS

Google DevelopersWhen your ISP’s Domain Name System (DNS) is out of service, you may experience problems browsing the Internet. In this case, it may be a good idea to use an alternate DNS for temporarily bypassing the problem. A good choice is to use the free DNS from Google. Here is the technical information.

If you have multiple computers in your network and don’t want to change the TCP/IP settings on each computer, you can change the DSN settings on the router and restart the router. All computers will take the new settings next time they connect to the router.
