David L. Farquhar on technology old and new, computer security, and more
Computers in 1980 were rather different from computers of today. They could do the fundamental things a computer of today can do, but by modern standards, they were much smaller and less powerful. In the mid 1980s, Commodore Grace Hopper said we had the Model T, computing-wise. In 1980, we weren’t quite at the Model T yet.
Still, computers in 1980 were interesting. We’d never seen anything like them.
The IBM PC and Commodore 64 were introduced about a year apart. The PC came out in 1981. The 64 followed in 1982. They were two of the most important machines of the 1980s, and both have long legacies. Here’s the story of the Commodore 64 vs IBM PC.
Although the two machines share a legacy, for the most part they existed in different worlds.
People frequently ask me how long to study for CISSP. Unfortunately it’s hard to give a set answer for that, but I can tell you how to figure out how long you need to study for it. That’s almost as good.
Don’t believe anyone who tells you they can get you ready in x number of days or weeks or even months. No one can know where you are relative to what you need to know to pass that test.
What does IBM do now? Does IBM still make computers? If not, what does IBM make now? IBM’s days as the dominant maker of personal computers ended long ago, but IBM is still #32 on the Fortune 500 list.
How does IBM make money without selling anything to consumers anymore?
Setting up a Christmas village can be a fun way to decorate for the holidays. Some people set up rather elaborate and impressive displays. Here are some Christmas village set up tips and layout ideas from a model railroader.
Some people build villages with hundreds of buildings. Not everyone has that the space or budget for something like that. Even with a modest collection, you can set up a memorable village. Here’s how.
I need a quiet mechanical keyboard. I also want it to be small, to fit on my laptop desk. And I want it to be cheap. And durable. I don’t want much, do I? I might as well ask for world peace while I’m at it.
The Velocifire TKL01 claims to be all of the above, and delivers more than I expected.
If you’ve ever looked at the back and wondered what all the Commodore 64 connectors are for, wonder no more. I’ll explain them to you.
A CISSP is a professional certification. To attain CISSP, a professional must pass a six-hour, 250-question test and must have five years of professional experience doing work related to computer security. But after attaining the certification, what does a CISSP do?
An easy question on the test would involve what you have to be concerned about when running network cable through an HVAC duct. A medium-difficulty question might ask whether the CDMA or GSM standard for cell phones is more secure, and why. A hard question or series of questions would involve reading several pages of executive summary about a data breach and making recommendations to prevent it from happening again.
Tootsietoy wheels frequently go missing. Sometimes they dry-rot away. Sometimes kids played with them to death. Tootsietoys with missing wheels usually sell cheaply. Unused, old factory-stock Midgetoy tires are readily available and fit perfectly. But it can be fun to make your own. Here’s how to make your own Tootsietoy tires.
If you’re curious about Mike Schmidt rookie card value, I have good news. Good news if you want to sell, that is. Mike Schmidt’s rookie card is one of the most valuable cards of the 1970s. Mike Schmidt needs little introduction to baseball fans, but if you’re not, that’s OK. Here’s what makes Mike Schmidt’s rookie card a great card.
