I’ve been asked several times about Microsoft Silverlight — what is it and do I need it.

Silverlight is Microsoft’s competition for Adobe Flash Player. It’s designed to play videos and allow interaction with the program.

My initial thoughts were that I didn’t need it. I had no application that areqired it and I did not need yet another video display system on my computer. I already had Windows Media Player which could handle video streaming. I already had JavaScript and ActiveScript (Microsoft’s name for its JavaScript interpreter in Internet Explorer). I already had Adobe Flash Player. Wy did I need Silverlight?

I managed to do without Silverlight all through the first version, which was released in 2008. However, in early 2009, I finally had to install it — it was required for one of my new applications.

Subscriber JNC wrote to me to say that he’d been using Acronis True Image for a while and wanted to know about keeping old backups:

I have just completed a total backup via Acronis on my external hard drive. Is there any reason to save previous total backups?
My external (500) hard drive is over 2/3 full.

I wrote back to JNC to say that I wouldn’t get rid of all of them. I suggested that he keep some recent ones and one or two full backups from the past — including the oldest one he had.

I find that, most of the time, I’m reaching for a backup file or backup image file because my brain messed up, not because of a hardware failure. It’s too easy to change a file and not realize that we haven’t done the change correctly. We find it out later when we try to use the file, or that part of the file. It might be days, weeks or even months later.

First, let’s be very clear. Google’s new web browser “Chrome,” which you can download via the link Google’s main search page at www.google.com — is a Beta version — an unfinished version that is being released to the public so they can help find the bugs before the official release.

Tech Tip
A beta version of software is an unfinished version of software that is released to a large group of testers (sometimes the public) for testing, in order to help identify any bugs that still exist.

Chrome is not finished. It is not bug free. It is not free from security problems. The whole purpose of a beta release is to get more people trying to use it in order to find the bugs. Use it at your own risk.

If you are considering trying Chrome, or even starting to regularly use Chrome, I strongly urge you to carefully read the Google Chrome Terms of Service, which you have to accept in order to download the Chrome Beta.

EJ wrote to ask about backing up his computer:

Terry, what program do you use to back up your files

I use two programs routinely.

First, every evening, I use Karen’s Replicator (www.karenware.com, free for personal, non-business use) to copy my data files to another computer across my home network. Not only does this give me a backup copy in case of the inevitable, accidental error (such as editing a file, saving it, and then realizing that I forgot to save it with a different file name), it also gives me a backup in case of a failure of my hard drive.

Replicator lets me set up multiple tasks and specify the day of the week and the time for them to be performed. If I set several for the same time, they will run in the order listed.

I also use Replicator to make a backup of certain files on my hard drive to another location on my hard drive. This gives me an easily accessible copy for that brain-freeze error.

Then, on a weekly basis, I use Acronis True Image Home 11 to make an image of my C: drive. I have True Image set to store that image on another computer on my home network.

OK, you have a new computer and you’ve made the decision to keep your old computer, and you want your spouse and children to be able to do email and surf the web without demanding your computer.

Let’s assume you already have an existing home computer network — if you don’t, the first article in this week’s online newsletter is for you…

There are two basic ways that computers on home networks can get the IP addresses and other network data they need in order to communicate with each other: we can enter the data into the configuration screens, if we want to use static (unchanging) IP addresses, or we can set the router to assign IP addresses dynamically using DHCP.

I’m often asked about how I handle passwords for all the different sites that require passwords.

The questioner’s eyes get pretty big when I mention that I use random mixtures of letters and numbers for my passwords, and even bigger when I say that I use a different password on every site.

The immediate question is “How can you keep track of them all?”

The answer is one of the reasons that I use a PDA, a Personal Digital Assistant. In my case, it is the PalmOS v4 based Sony Clié SJ-33, which I’ve used for a couple years.

If you’ve been using computers for any length of time, you’ve had the problem.

Maybe you haven’t had a hard drive fail, yet, but you’ve managed to delete or overwrite one of your data files with a changed version — and immediately said “Oh, NO!”

Most people have the problem and have no way to recover a copy of their older version. But you can, if you make a habit of backing up your data.

Karen’s Replicator ( www.karenware.com ) is a great program that I use for making backup copies of my data files. With Replicator, I can schedule backups of any modified files as often as I like. I can back up to a different directory on my hard drive, to a different hard drive (internal or external) or even to a directory on a shared drive across my home network.

By scheduling a daily backup of my data files, I know that…
