There have been a number of wonderful inventions during the 20th and 21st century. Some of these creations have been both massive and minute. Very few of mankinds modern creations have revolutionized working life so much as the USB flash drive though. Ok now that might seem a bit much for some people but the reality remains the same - USB flash drives have made the working lives of millions of office workers, teachers, students, IT and other professionals massively more simple. If you already one (or a few) USB flash drives then you’ll know just how incredibly useful they are. If you don’t already own at least one USB memory stick then hopefully this article will help convince you of their absolute usefulness in both your working and personal life.
So what’s so great about USB flash drives?
Small
Prior to the creation of USB flash drives all external storage devices for computers were either bulky or awkward (dozens of blank discs for example) or sometimes an annoying combination of being both bulky and awkward. USB flash drives are also called Thumb Drives because they’re about the size of your thumb (although some are much smaller now) and you can easily fit several gigabytes of data in your jeans or shirt pocket thus eliminating the bulky and awkward factor straight away.
Portable
USB flash drives are about the single most portable data backup device possible. They don’t require an external power source of any kind, nor do you need any cables or tools to set them up and last but not least they don’t require any additional software to be installed for them to work on any modern computer (Windows XP, 2000 and Vista and most Macs) so you can quite literally pick them up and use them anywhere you want.
Reliable
Once the data is stored on a USB flash drive you can rest assured that it’s going to stay there and be there when you next need it. This is totally unlike the world of floppy disks or rewriteable CD/DVD discs where they can just stop working for no apparent reason. Flash drives were built to provide consistent and reliable performance. Most of these drives come with built-in write protection to prevent you from overwriting your own important data - if you were silly enough to do so.
Tough
For years people fiddled with boxes of floppy disks and CDs/DVDs. These were bulky, easily lost and easily damaged. External hard drives also provided another method of transporting data between systems but the smallest jolt was and is enough to kill an external hard disk stone dead. USB flash drives are based on what’s called Solid State Memory - this simply means that it’s the same as standard computer memory in that it has no moving parts and is therefore almost impossible to damage (except for jumping up and down on it or maybe hitting it with a hammer for example. Please don’t test either of these theories at home!)

Tech support tells me to type ‘regedt32′ as opposed to ‘regedit’ to access the registry from the command line (Start > Run). I question the use of ‘regedt32,’ but he says to do it anyway. Whenever I use the registry editor, I recall this incident and never look up the tale of the two regs… until now.
Regedt32.exe is an alternative registry editor available with Windows NT/2000 with features of its own. Regedt32.exe does not support importing and exporting registration entries (.reg) files. Regedit has limitations of its own as quoted here:
“You cannot set the security for registry keys. You cannot view, edit, or search the value data types <>REG_EXPAND_SZ and <>REG_MULTI_SZ. If you try to view a <>REG_EXPAND_SZ value, Regedit.exe displays it as a binary data type. If you try to edit either of these data types, Regedit.exe saves it as <>REG_SZ, and the data type no longer performs its intended function. You cannot save or restore keys as hive files.”
Research indicates regedit has:
- a better search tool
- bookmarking of subkeys
- opens to last edited subtree, export and import capabilities
- all keys are visible from a window similar to Windows Explorer
Regedt32 (pre-WinXP) can:
- run in read-only mode
- allows you to edit values longer than 256 characters (who wants to do that???)
- displays subtrees in their own windows
- modify access permissions to subtrees, keys, and subkeys
In WinXP and Server 2003, the two have been replaced by a new version of regedit that has features from both. Try typing ‘regedit’ and ‘regedt32′ to see what happens. They’re the same. To prove it, while in ‘regedit,’ select ‘edit’ and you’ll see ‘permissions.’ This is a feature that was only available in the old ‘regedt32′ and not ‘regedit.’
Technically, regedt32 is a small program that runs regedit. So when typing ‘regedt32,’ it takes you to ‘regedit.’ The destination is the same either way. So type whichever is easier for you to remember. Regedit is easier for me - I had to play with the spelling of the other version until I got it right.

Scenario: You work in a corporate environment in which you are, at least partially, responsible for network security. You have implemented a firewall, virus and spyware protection, and your computers are all up to date with patches and security fixes. You sit there and think about the lovely job you have done to make sure that you will not be hacked.
You have done, what most people think, are the major steps towards a secure network. This is partially correct. What about the other factors?
Have you thought about a social engineering attack? What about the users who use your network on a daily basis? Are you prepared in dealing with attacks by these people?
Believe it or not, the weakest link in your security plan is the people who use your network. For the most part, users are uneducated on the procedures to identify and neutralize a social engineering attack. What’s going to stop a user from finding a CD or DVD in the lunch room and taking it to their workstation and opening the files? This disk could contain a spreadsheet or word processor document that has a malicious macro embedded in it. The next thing you know, your network is compromised.
This problem exists particularly in an environment where a help desk staff reset passwords over the phone. There is nothing to stop a person intent on breaking into your network from calling the help desk, pretending to be an employee, and asking to have a password reset. Most organizations use a system to generate usernames, so it is not very difficult to figure them out.

I was reading The Big Moo: Stop Trying To Be Perfect and Start Being Remarkable this morning, and I’d recommend a copy of this to anyone who wants to improve their career and their future. And that’s all of us, right?
There was one particular line that really stood out to me: Betting on change is always the safest bet available. That describes life perfectly, but it also describes a career in Information Technology perfectly as well. There is no field in the world that has the constant and never-ending changes that IT does. And every single one of us can look at this as a massive opportunity for personal and professional growth.
Is that how you’re looking at it? I remember when I passed my first certification exam, the Novell CAN, back in 1997. Man, I thought I knew it all then! But I quickly learned that you’ve got to keep learning in IT. I also learned that if you’re willing to put in the work and make the sacrifices, there’s no other field with the limitless potential for growth and excellence.
Like everyone else, my career has had its ups and downs, but I always kept learning and growing. Today, I’ve got my dream job, working with studI was reading The Big Moo: Stop Trying To Be Perfect and Start Being Remarkable this morning, and I’d recommend a copy of this to anyone who wants to improve their career and their future.
