How Much Data Is That?
Whenever we discuss quantities of data, we tend to do it in the abstract. We speak of a kilobyte, or a megabyte or a gigabyte without really knowing what it represents.
The following table shows various quantities of bytes, in each power of ten. Usually, they are shown with multiples of 2 and 5 also. For example, 1 Kilobyte, 2 Kilobytes, 5 Kilobytes.
All the examples are approximate and are rounded. For example, a computer card has 80 columns. If 50 columns contain data on a card, then two cards will be 100 bytes. Also, a 3-1/2 inch diskette can contain 1.4 Megabytes. Showing it as 1 Megabyte reflects both (a) the diskette not typically being filled and (b) rounding. Finally, a CD-ROM can hold more than 500 Megabytes. However, it is listed at that level as "typical" and as the closest match.
Bytes (8 bits)
1,024 bytes; 210;
approx. 1,000 or 103

"The Alchemist" Keyboard
This keyboard was originally designed for a pharmacist and is themed around Apothecarial and Alchemical icons including the Bowl of Hygeia, the Caduceus, and the Eye of Ra (from which the modern "Rx" symbol used by pharmacists is derived).
The side lighting is wired into the scroll lock LED and turns on with a press of the scroll lock key. It is a USB keyboard, but because the lighting is hooked into the scroll lock function, this keyboard is designed for a PC, not a Mac.
The function keys display the elemental symbols of the various metals used in the construction of the keyboard, as well as a few others. The tilde and number keys display the symbols for the sun, moon and the planets.
The symbols for Earth, Air, Fire and Water are found on the arrow keys and the number pad uses stylized Roman numerals. The Enter and Shift keys are labeled with the symbols for Alchemical processes like mixing, stirring, combining, etc.
Secundum artem is a Latin phrase meaning "according to the art." It is frequently used to describe doing something in the accepted manner of a skill or trade; in medicine, it is often taken to mean "use your skill and judgment." The brass rod on the front of the keyboard (where you can see the reflection of my camera and overhead light) is covered with a piece of transparent vinyl to prevent tarnishing from the oils in the skin of your wrists.
This keyboard also features a "braided brass" cord.

10 Myths About Introverts
Myth #1 – Introverts don’t like to talk.
This is not true. Introverts just don’t talk unless they have something to say. They hate small talk. Get an introvert talking about something they are interested in, and they won’t shut up for days.
Myth #2 – Introverts are shy.
Shyness has nothing to do with being an Introvert. Introverts are not necessarily afraid of people. What they need is a reason to interact. They don’t interact for the sake of interacting. If you want to talk to an Introvert, just start talking. Don’t worry about being polite.
Myth #3 – Introverts are rude.
Introverts often don’t see a reason for beating around the bush with social pleasantries. They want everyone to just be real and honest. Unfortunately, this is not acceptable in most settings, so Introverts can feel a lot of pressure to fit in, which they find exhausting.
Myth #4 – Introverts don’t like people.
On the contrary, Introverts intensely value the few friends they have. They can count their close friends on one hand. If you are lucky enough for an introvert to consider you a friend, you probably have a loyal ally for life. Once you have earned their respect as being a person of substance, you’re in.
Myth #5 – Introverts don’t like to go out in public.
Nonsense. Introverts just don’t like to go out in public FOR AS LONG. They also like to avoid the complications that are involved in public activities. They take in data and experiences very quickly, and as a result, don’t need to be there for long to “get it.” They’re ready to go home, recharge, and process it all. In fact, recharging is absolutely crucial for Introverts.
Myth #6 – Introverts always want to be alone.
Introverts are perfectly comfortable with their own thoughts. They think a lot. They daydream. They like to have problems to work on, puzzles to solve. But they can also get incredibly lonely if they don’t have anyone to share their discoveries with. They crave an authentic and sincere connection with ONE PERSON at a time.
Myth #7 – Introverts are weird.
Introverts are often individualists. They don’t follow the crowd. They’d prefer to be valued for their novel ways of living. They think for themselves and because of that, they often challenge the norm. They don’t make most decisions based on what is popular or trendy.
Myth #8 – Introverts are aloof nerds.
Introverts are people who primarily look inward, paying close attention to their thoughts and emotions. It’s not that they are incapable of paying attention to what is going on around them, it’s just that their inner world is much more stimulating and rewarding to them.
Myth #9 – Introverts don’t know how to relax and have fun.
Introverts typically relax at home or in nature, not in busy public places. Introverts are not thrill seekers and adrenaline junkies. If there is too much talking and noise going on, they shut down. Their brains are too sensitive to the neurotransmitter called Dopamine. Introverts and Extroverts have different dominant neuro-pathways. Just look it up.
Myth #10 – Introverts can fix themselves and become Extroverts.
A world without Introverts would be a world with few scientists, musicians, artists, poets, filmmakers, doctors, mathematicians, writers, and philosophers. That being said, there are still plenty of techniques an Extrovert can learn in order to interact with Introverts. (Yes, I reversed these two terms on purpose to show you how biased our society is.) Introverts cannot “fix themselves” and deserve respect for their natural temperament and contributions to the human race. In fact, one study (Silverman, 1986) showed that the percentage of Introverts increases with IQ.
