TLDR: Download the coin here: https://www.thingiverse.com/thing:5904625 The Chinese used had shells well before 1,000 BCE as gifts, especially those bestowed upon the people from their aristocracy. Those were used in religious ceremonies and some hypothesize that imitation shells were used as a form of currency as far back as an estimated 700 BCE, around the time the bronze age ended in China. Knife money, or knife-shaped money began to be used in China in the centuries after 600 BCE. Spade money, or money that physically resembles a spade, began use some time after 640 BCE, which actually makes it far older than the stater, but it’s theorized they were used…

A Brief History of Time
Noooooo – a different Brief History of Time… Time is important; so important that it’s epic! Or epoch more specifically. The epoch is a date and time from which a computer measures the time on the system. Most operating systems derive their time from the number of seconds that have passed since January 1st, 1970 when the clock struck midnight. Why? Because this is when time began – likely the Catch-22 the movie, which came out later that year was made based on this fact. As with most things awesome in computing, this came from Unix. More specifically, taken from Unix Epoch time. MATLAB uses January 0, 1BC – which…

A Thermometer For The iPhone
The practical uses of Wearables and Home Automation never cease to amaze me. I recently added a Kinsa thermometer to my collection of useful toys. This little device uses the 1/8th inch jack like the original Jawbone did. It works like a regular thermometer, but displays temperature on an app that runs on the iPhone. It’s simple to setup and once setup, works the same as any other thermometer. Due to the power of the Internets, you can then select symptoms and check for common ailments that match. You can also look at your history, tracking the rise and fall of your temperature. Overall, a cool little device and a…

Bash History Fun
We tend to use a lot of commands in the Terminal app. That is, after all, what it’s there fore. And there’s a nice history of what we do. There are also a number of ways to view and manage the bash history. The simplest of which is the history command, which will show the previous commands run. Here, we’ll simply run it: history Keep in mind that this shows the history based on context, so if you sudo bash, you’ll potentially see a different history. You can also use the bash built-in fc command, which has the additional awesomeness of being able to edit and re-run commands from the…

Leveraging The Useful Yet Revisionist Bash History
Not, this article is not about 1984. Nor do I believe there is anything but a revisionist history. Instead, this article is about the history command in OS X (and *nix). The history command is a funny beast. Viewing the manual page for history in OS X nets you a whole lotta’ nothin’ because it’s just going to show you the standard BSD General Commands Manual. But there’s a lot more there than most people use. Let’s take the simplest invocation of the history command. Simply run the command with no options and you’ll get a list of your previously run bash commands: history This would output something that looks…

Hit Apple-I on any page and then click on the security tab. Right there in the Privacy and History section there it is. IMHO Not very private.
