Freelancers often have time keeping track of their billable hours and invoicing their clients for the time. Besides doing the work, freelancers are responsible for the administrative work, which is not billable. Below are some services that can help the freelancer keep track of their time and invoice it.

PC Antispyware 20XX is a fake antivirus program, called malware. It pretends to scan your computer, detects false positives, and then invites more programs to download. Each one charges you money for an upgrade that does not do anything.

If you are having trouble making phone calls using Google Voice on your Android phone after installing it, the problem may be the way your phone number is written in the Google Voice settings. For some reason, the Google Voice application for Android phones requires that your Android phone's number be in the international calling format. If you are in the United States, you must change your phone number to the +1-xxx-xxx-xxxx format. 

A recent experience with a wireless print server that connects to a printer via USB has left me wary of using such print servers. USB-based print servers should be checked for compatibility with the printer you intend to use. This is not an off-the-shelf setup. Old parallel cable based print servers were less finicky about which printers you could connect. Getting incompatible printers and print servers can be costly because stores are not willing to refund your money; they would rather offer store credit. Moral of the story, really do your homework before trying a wireless print server that only connects via USB.

It is possible to use your HD television as a computer monitor at home or at work for presentations. With the sizes of modern televisions, it is a toss-up whether to use a television or a projector, especially in a small group. Obviously, large audiences still benefit from projection.

Since High Definition televisions started production, they have typically had several different connections possible. They allow for cable, HDMI, component, DVI, and VGA connections.

Computers use VGA and DVI connections. The connection on the television will look exactly like the connection on the computer. You will need to run down to your local computer shop to purchase a male-to-male VGA monitor cable. If there is no computer shop nearby, you can purchase an affordable one at Amazon.com (10ft Hi Resolution monitor cable (Male to Male)) OR (DVIMM6 6' Digital LCD Monitor Cable Replacement DVI-D Male to DVI-D Male 4.95 GBPS).

You should be aware that this only allows for sharing the video signal from your computer or laptop. Audio would still come from your computer. If you want to use audio through your television, then you may go with component or HDMI.

I have known people who use their LCD televisions as computer monitors all the time. This frees them from using their glasses to see the details on their screen. If you are thinking about using your HDTV as a full-time monitor, you may consider changing your video card to one with HDMI so that you can take full advantage of the high definition display.

I recently had to put together a PDF out of several scanned TIFF files. The computer did not have any PDF authoring software and was operating on dial-up, making downloads painfully long. I downloaded the TIFF documents onto a thumb drive and then drove to the office to convert these into PDF.

I would have used Acrobat.com to convert the TIFF files to PDF, except that they only allow up to 5 documents free. Instead, I headed over to media-convert.com to convert all 9 TIFF files into PDF. This yielded 9 PDF files.

Once converted, it was simply a matter of using PDFTK Builder Portable, an application that runs on the PortableApps package, to combine the PDF files into one single file.

There are currently no applications for PortableApps that will scan documents directly or create PDFs. If I had a an Apple computer, output to PDF comes standard. I simply would have opened the TIFF files and printed to PDF. However, I am not familiar how a Mac would combine several PDFs into one.
