Some thoughts on solving virus problems
Short Background:


My computer career started about about 46 years ago. The first computer I worked on was an IBM 7094 - I wrote a Fortran program to find the inverse of a matrix to teach myself programming. This landed me a job as a Fortran programmer - since nobody (relatively speaking) had experience with Fortran. Since then I remained in programming from Fortran, Cobol, PL/1, etc on mainframes to the PC. I have been repairing, building, etc. PCs for about the last 20 years. Mostly, I now "fix" computers by removing viruses, malware, etc. I usually advise my clients to buy a new machine if they have serious hardward problem - since the cost of a PC has dropped dramatically over the last few years. Since most virus behavior varies wildly - I don't use the same protocol to remove a virus. So here are a few things I try to do CONTINUE...

anti virus help Why is the reported physical usable memory ( RAM)
less than the actual installed memory in
windows 7 ?


There is not a simple explanation for the difference. But I will try to summarize as best as possible. According to microsoft, the usable physical memory available for your computer is the total physical memory minus memory that is reserved by the hardware. For example, a video adapter that has 1 gig of onboard memory has this memory "mapped" to the computer's RAM memory thereby making this 1 gig of physical memory unavailable for the operating system and your applications. Another factor is the motherboard. The chipset on the motherboard must be able to support more address space ( probably by a factor of 2 ) than the total installed physical memory. A third factor is the version of windows 7 that is installed , ie , 32-bit or 64-bit. CONTINUE...

anti virus help Artificial Intelligence - Is it a fraud and a Sham?

Well, it's been many years now and the promise of artificial intelligence ( AI ) still seems to be about where the promise of controlled fusion is currently - nowhere! All the talk, both past and present, about the benefits humans would reap from this pursuit still seems elusive as ever. I remember, back in the 60's, while working in a lab, how excited me and my colleagues were when we got our first computer - it was an IBM7094. One member of our group "discovered" a program that would "learn" how to play tic-tac-toe. This was exciting stuff - a computer would actually "learn" to do something. Sure enough, the program would lose the first several games against humans but eventually it "learned" to play at a level such that it would consistantly play to a draw. Upon analyzing the program, it turned out that all the program was doing was storing a history of moves and categorized the moves that would lead to a loss. Eventually, it had enough games stored so it would no longer lose. What a disappointment! This was not learning as one would intuit learning to be. CONTINUE...

visual basic code examples What's the Code?

Recently, I did a project in Visual Studio Basic for a friend. This is an inventory control and reporting system for an antique store. I have some code examples from this project which may be of some help to some of you. These examples will read an MDB database and extract some values and save them to a text file. The code illustrates the following:

1. Access an MDB database using a connect string. If you have ever tried this - it can be painful as the varying syntax levels may drive you to drink - see link HERE
2. Replace characters in a string.
3. Replace null values.
4. Write to a text file.

microsoft and macintosh comparison Oh Microsoft, how do I love thee .....
let me count the ways.


Well, not really. I admit that, I have been in the microsoft camp ever since its inception and somehow missed getting on the Apple express. And yes, I am sure the Apple dumpling gang would be able to count the ways they love their Macs. I can easily understand why Mac users love their Macs. MSDOS was intimidating to anyone new to computers, although I felt right at home using command line prompts as I came from a mainframe background ( IMB360's ) and TSO - ie, Time Sharing Option to connect to the mainframe.

how to figure out file type with no extension How to handle a file with no or an unknown extension

Unlike the file names in Macintosh or unix, Microsoft decided to add extensions to the names of files so they could be associated with the application that created them. This was done, so when you double click on a file - windows will open (read) the file with the correct application that created it. CONTINUE ...

Dedicated to My Old Pal Google

This music is dedicated to my old pal Google. In appreciation for cutting off my adsense account. Thanks.
Respectfully, PCT

Okay, somebody didn't like my sarcastic music choice and sent me the following:
What pitfalls to avoid if you are using Google Adsense to make money on your website
From: A Contributor

Google Adsense has always been the main income source for many people who have high traffic on their websites. There are lots of money that can be made in this business, and those who plan to use this as an income source need to know about the Do's and Don'ts in order to achieve success with this method. The truth is that many marketers make thousands of dollars almost everyday with Google Adsense. The only reason why so many people fail is because they don't do what's right for their campaign.

odd behavior in windows Well, That's Odd - Bizzare quirks in Windows

I recently came accross some odd facts about Windows. It appears that you cannot create a folder or file with the name "con" and it has been reported that Microsoft could not give a reason why this should happen. I tried to do this using both a window interface and a command prompt. I also tried to rename some file ( called it con1) to "con". No dice - you cannot do it.

The next oddball has to do with the Notepad program - Open notepad and type in the following ( exactly as shown - the "B" is uppercase):
Bush hid the facts
Now save this into a file (give it any name you want ) and re-open it. The text now looks like it is chinese and MS could not explain this either. It will work correctly if you make the "B" in Bush lower case, or if you change any other letter to uppercase. Now, that's odd!
