Rules for Well Behaved Window’s Utilities

Written by BobW on August 20th, 2010

There are many excellent software utilities available for Windows. There are also many other utilities that have great potential, but missed the mark because of poor program design. I am careful about the impact a program has on my computer. Sometimes programmers fail to realize that I use my computer for many tasks besides occasionally running their program. I may only run their program once a month and I expect their software to maintain a small footprint on my computer.

Run Windows on Multiple Domains and IP addresses The Easy Way

Written by BobW on June 5th, 2010

If you plug your laptop into different corporate networks as I do, you might run into some common Windows network problems.. I will share my solutions to these problems. Since I am an Embedded Systems consultant, I frequently take my laptop computer with me when I visit clients. I connect to my clients networks for internet access. I may also need a static IP on a different subnet to talk to the development hardware project I am working on. The first problem I face is that Windows does not have a way to set up a computer with multiple IP addresses, unless you have multiple network adapters. When I connect to the development network which is isolated from their internal network, I loose internet access. Switching back and forth between networks is not very practical. The second issue is that Windows only allows computers to be part of a single Windows Domain (different from Windows Workgroups). Each client has a different domain to connect to and switching domains is even more problematic.

Why you should Avoid Checksums and Use CRCs Instead

Written by BobW on April 20th, 2010

Error detection is an important consideration for the designers of embedded systems. When the computer in your spacecraft sends a message to the main engine to shut off, it is important to make sure the message is received correctly. You want to make sure it can tell the difference between commands to, turn on, turn off, and self destruct. You might choose to use a “standard CRC algorithm” to guarantee the integrity of your data transmission. However, you might be surprised to find out how many “standard algorithms” there are. Here is some information to help you choose your implementation wisely.

Windows 7 Tip: Elevated Command Prompt Anywhere

Written by BobW on April 8th, 2010

When running Windows 7, I found that I really missed the Window XP Power Toy, Command Prompt Here.

Well, I found out that this feature is now built into Windows 7,  along with some extra goodies. Check it out! Click to continue »
