Khan Academy

Today I added a link to the Khan Academy’s website (see links under “Education”). The Khan Academy is run by Salman Khan and makes available to the public over 2100 online training videos. These videos are heavy in math, but there are also other subjects covered such as Banking, Biology, Chemistry, Economics, and more. He began making math videos for family members who were struggling in school, and over time it just sort of snow-balled from there.

I am linking to his site because I have personally sat through several of Salman’s videos, and I have to say they are of a very high quality, and in my opinion, worth your time to watch.

Regarding his math-focused videos, the videos start as simple as basic arithmetic and range through advanced calculus. His videos are not “dry,” but rather are very engaging, and he has a gift for making information very straight forward and understandable to the common man. Every so often he includes videos where he does nothing but work out problems related to subjects that he recently covered. Because he doesn’t leave out steps when solving these problems, students of ANY level can follow along.

Best of all, Salman has made ALL of these videos available FOR FREE.

No, neither I nor CompuBlab get any compensation for singing the praises of or directing traffic to his site. I am linking to the Khan Academy for no other reason than I think it is a WONDERFUL resource and I want to make as many people aware of it as possible.

So go over and see what Salman has done. If you like his work, be sure to spread the word. In my opinion, Salman Khan has demonstrated a great application of technology.

SecureID by RSA Hacked!

Some very unsettling news about Secure ID tokens. Don’t know what a SecureID token is? Perhaps you have one but don’t know it by name.

A SecureID token is a small little device that can fit on your keychain. It is used as an extra layer of protection for when you log into a computer system. You see, the SecureID Token displays a number that changes every so many seconds. Through some computer trickery, the computer you are trying to log into (that is set up to use a SecureID Token) can calculate the SAME number that your SecureID Token is currently displaying. The theory behind this is that if someone manages to get a hold of your User ID and Password, they STILL cannot gain access to your account with the SecureID Token number…which presumably only YOU have in your possession.

Well, that entire game just changed,

You see, RSA, the company that makes the SecureID Token, reported recently that there was an intrusion/break in/hack into THEIR computer systems, and the hackers were able to steal enough information to be able to figure out what the SecureID Token number should be for a person’s SecureID Token…effectively rendering your SecureID Token useless (click here for the original story).

Now, the thing you need to understand about system security, and the thing you are going to read from me over and over again, is that there is no such thing as a completely secure computer system. The best you can hope for is to keep the amateurs away from your data, and to give the professionals a reason to go look elsewhere for the jollies (because your data is going to be so hard to crack). Of course, some hackers relish a challenge, so you have to be careful even there.

But the overall point here is that you may be able to protect your data for a while…but eventually, given enough time, hackers WILL be able to compromise your data if they have any way of actually reaching it. Of course, if your data is not accessible from the Internet, then the only way for them to steal your data is to physically enter your premises to do so.

So as far as computer security goes, I think of it the way my parents taught me to think about car thieves. We lock our doors to keep the pranksters away and to try to encourage amateurs to find another car to steal…one that is easier to break into. However, if a professional REALLY wants your car, there is virtually NOTHING you can do to stop them.

So if you have an RSA SecureID Token, be sure to get it replaced right away! The article that I liked to previously already tells of people havingt had their accounts broken into based upon what the bad guys learned from their hacking into the RSA network.

You have been warned!

Where to Begin?

Ahhh…the start of a blog. Where do I begin? Certainly not by telling you WHY I am writing this blog. That is already available on the About Us page. I guess to let you know that I have been giving though to the content of this blog for some time, and I am every so glad that the day has arrived where I can begin to add content.

So sit back…relax…and prepare for a ride!

Greetings To All!

This post commemorates the official opening of CompuBlab.com! We hope you will enjoy it…
