Using spreadsheets for home economics.

I love spreadsheets.  With a few formulas you can calculate your budget, right down to the earth’s gravitational field.

They can also help you calculate the TOC of an operation, in realtime, and make more accurate analysis when doing logistics.

This is especially useful when you’re moving to another city. Especially if you’re someone who travels light, is a practitioner of simple living and just want to know just how much you have and how that will affect your personal economy.

Well for me, since I am currently moving to another city, I wanted to know how much moving in my new  place would cost.

So I did a new workbook and divided it into three sections. The first is belongings, the second is groceries and installation fees and the last is “Grand total”.

In the “belongings” sheet I put the item name, the quantity and the Cost and if I had already acquired it or not. In “groceries” I had put the same.

The two, I linked their totals to the Grand total sheet, that way each time I changed a value on either of the pages, I would be able to quickly know how much money it had cost .

While simplistic, this can help one to be organized and really help you erase the stress of moving, or at the very least see how much this is costing you and what adjustments you will need to make financially.

The very same can be applied to all kinds of home economic projects, I will include these links to other useful excel workbook templates;

And for the libre-office/Open-office calc fans

Musings- Google’s eyeglass. The apple of my eye or a black eye?

As many of you have heard, Google has come up with the first borg implant called “Project glass”.

In a nutshell, it’s an augmented reality device, Google’s answer to Apple’s Siri.

In a small video promotion that demonstrates the basic use of it, reminds me of what if your life was a cheesy videogame (Think SNES “Lester the unlikely” or The Leisure Suit Larry series). It displays many features, including music, GPS, basic communications, is voice activated and gives even the capability to share the view of the built in camera.

The device itself, while lacking elegance, looks somewhat promising. However, it brings many concerns to my mind, mostly privacy and security.

Such a device is obviously light-years ahead of what’s found in your office and for one, The industry is still trying to figure out how to best implement security to tablets and smartphones which carry a ton of security issues.

The built in camera and visual recognition system is enough to be cause for concern. Never mind company meetings being leaked or company assets suddenly becoming public domain. And don’t get me started on the peeping toms who would immediately share their point of view.

From another angle, with the ever-nagging tendencies of late with governments wanting more and more control over the internet, now everyone with such a device could become a walking talking surveillance camera. What would stop a government from doing a man-in-the-middle attack and basically hijacking your POV?

You can see where this is going!!

On the flip-side, I can only imagine the great uses for this device or similar in the fields of medicine and engineering. As long they are secure and kept on an internal server uplink, I can see many benefits.
