do you know the origin of zero?

Image
Rolf, New York, NY.  Robert Kaplan, author of The Nothing That Is: A Natural History of Zero, provides this answer:

The first evidence we have of zero is from the Sumerian culture in Mesopotamia, some 5,000 years ago. There a slanted double wedge was inserted between cuneiform symbols for numbers, written positionally, to indicate the absence of a number in a place (as we would write 102, the '0' indicating no digit in the tens column).

The symbol changed over time as positional notation, for which zero was crucial, made its way to the Babylonian empire and from there to India, via the Greeks (in whose own culture zero made a late and only occasional appearance; the Romans had no trace of it at all). Arab merchants brought the zero they found in India to the West, and after many adventures and much opposition, the symbol we use took hold and the concept flourished, as zero took on much more than a positional meaning and has played a crucial role in our mathematizing of the world…

computer slowing down? could be the hard drive

What are the factors that most affect the performance of a hard disk?

The performance of a hard disk is most affected by its interface and its spindle speed. The spindle speed decides how fast data can be read from and written to the hard disk platters. Therefore, the higher the drive’s rotations per minute (rpm), the faster its data transfer speed. Understandably, a drive with more rpm is more expensive compared to one with a lower spindle speed. Recently, the advent of solid state drives, commonly called SSDs have threatened the existence of traditional hard drives. SSDs have a significant advantage as they do not have moving parts since they are flash-based memory.

Why do my applications slow down over time?

Every time you work with an application, the operating system creates numerous temporary files that are required by active applications. These files tend to be scattered all over the hard disk. Also, when you add or delete programs and files, it creates unused clusters of small …

Start small and pay off those loans. Here’s a list of ways to stretch your finances and account for every penny.

I have lost the original link but I guess it was taken from an MSN article somewhere in 2003 or 2004. Also, here is a list of books on Amazon, written by Mary Rowland.

Start small
Experts suggest you save 10% of your income. It’s a good goal. But don’t give up just because you can’t save that much. Establishing a savings habit and saving consistently is better than putting aside a big sum just once. Start with something you know you can live with — say, $25 a week. Promise yourself that you will save that much every Friday.

Sign up for the 401(k) plan at work
Contribute up to the amount of the company match, which is the amount your employer kicks in when you contribute. The most common match is 50 cents on the dollar. This gives you an immediate 50% return on your money.

Monitor your ATM withdrawals
Decide how much you will take out each week and make it last. Make …

I’ve learned that:

The best classroom in the world is at the feet of an elderly person.

When you’re in love, it shows.

Just one person saying to me, “You’ve made my day!” makes my day.

Having a child fall asleep in your arms is one of the most peaceful feelings in the world.

Being kind is more important than being right.

You should never say no to a gift from a child.

I can always pray for someone when I don’t have the strength to help him in some other way.

No matter how serious your life requires you to be, everyone needs a friend to act goofy with.

Sometimes all a person needs is a hand to hold.

Simple walks with my father around the block on summer nights when I was a child, did wonders for me as an adult.

Life is like a roll of toilet paper. The closer it gets to the end, the faster it goes.

We should be glad God doesn’t give us everything we ask for.

Money doesn’t buy class.

It’s those small daily happenings that make life so spectacular.

Under everyone’s hard shell is someone w…

Wondering why there's a 90s' digital camera on the post? It's because this is a post from the 90s. And why a still camera for a blog post on video? To fondly remember that not the same camera was used for photo and video as they do today. These tricks are here for adding that something special to the videos you’ve created. These tips are from late nineties - be warned, what you read might sound a little uncommon, but that’s okay. These theories were good back then - these are good today as well. Yes, there have been improvements in storage and graphics technologies in the past 20 years but the theory remains the same. This article lets you understand the humble beginnings of digital video.

Avoid Dropped Frames
If the system is slow, it may not write some frames to the disk and dropped frames will occur. The result is a null frame that takes up virtually no space and simply mimics the last frame. More dropped frames result in a jerkier video and are more apparent at low fra…

This is a fictitious conversation among Picard and his crew immediately after being confronted by a Borg ship.

Captain: "Mr. LaForge, have you had any success with your attempts at finding a weakness in the Borg? And Mr. Data, have you beenable to access their command pathways?" Data: "Yes, Captain. In fact, we found the answer by searching through our archives on late Twentieth-century computingtechnology." LaForge shows Picard the computing history from the archives in a monitor, and pauses the presentation at the Microsoft logo. LaForge: "As you can see, captain, the answer lies in Microsoft". Captain: "What the hell is 'Microsoft'?" Data: "Allow me to explain. We will send thisprogram, for some reason called 'Windows', through the Borgcommand pathways. Once inside their root command unit, it will begin consuming system resources at an unstoppable rate." Captain: "But the Borg have the ability to adapt. Won'…
