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…

In the Using Google Maps article, we saw how we could find a location on the maps. Then, we saw that we could see a satellite view and even a hybrid view with the map superimposed over the satellite view. We could zoom, too.

Google has another neat satellite-view program. This one is Google Earth, which is free and is part of the free Google Pack software package.

There’s not much I can say about Google Earth. That’s because I don’t know where to start…

Let’s try some bullet points:

• You start in space, looking at the Earth. You can turn the Earth with the pointers, or by dragging it, or by double-clicking on a spot.
• Continue reading Google Earth - A View from Space

I bought a new 1 GB SanDisk Cruzer Micro flash drive recently.

When I got to the store that had advertised the drive, they were nowhere to be found. When I asked about it, they had some “in the back.” If the store had actually had the items on the shelf, I probably wouldn’t have been surprised by the U3 Launcher that tried to install software when I inserted the flash drive into my computer.

I had just been reading back issues of Brian Livingston’s Windows Secrets newsletter — where he had the exact same problem.

The Cruzer Micro was actually formatted internally into two “drives”: one non-writeable “CDROM” drive (that’s the icon that Windows showed for it) and one writeable flash drive. In other words, SanDisk had grabbed a chunk of my flash drive’s memory, written auto-running software to it, and then made that portion of the drive non-writeable.

Subscriber Rolf wrote to ask about the speed differences between hard drive “virtual memory” and RAM memory chips:

Hello Mr. Stockdale,

Since you actively solicit questions in your newsletter I can therefore feel like I’m not imposing too much of your daily schedule to answer a question or two from those of us (like myself) who don’t have much computer savvy. As for me, well, I have more questions than you’d ever have time for; but for now I’ll settle for one question, and I thank you in advance for taking time for a reply. My question is this -

Kindly explain in as simple terms as you can why free or clear space on hard drives can’t act as readily or responsively in lieu of RAM. In other words … the so-called ‘virtual’ RAM. I’ve read in a few separate places that while a computer can use this virtual RAM, it doesn’t do it as efficiently as more available RAM chips, and that it is generally slower. Why can’t this virtual RAM process, then release data as quickly as normal RAM? Thank you. Rolf
