Cracking an Electronic Safe with a Raspberry Pi

by Jordan Spencer Cunningham on

I happened to lose the five-digit code for a SentrySafe (model KSW0510) that we had bought. Looking up the company’s website let me know that I could get the factory default combination from them again with a notarized form proving that I am who I say I am as well as $30. I knew of a couple of other things on which I could spend that $30, and I knew that the safe’s electronics were likely rather simple, so I opted to take the funner way out and use my programming and electronics prowess to crack the combination myself. This post outlines in good detail how I cracked the combination using a brute-force combination cracker I programmed in Python that interfaced with the safe using a Raspberry Pi. If you’re not very tech-savvy and just want to see the safe cracker in action, click here to skip ahead to the video of the finished product.

Human Data Overload Part II: Fixing It

by Jordan Spencer Cunningham on

See part one explaining the problem here

Since the dawn of the modern office, the common man has increasingly had to deal with the stresses of too much information causing him what is known as information overload. According to a study performed at the beginning of the internet’s explosion, “information overload occurs when the amount of input to a system exceeds its processing capacity”. The processing capacity of mankind has been pushed to its limits in the years since that study, and now society is facing unprecedented problems with stress, unproductivity, laziness, and even unfaithfulness all due to the vast increase in the overload of data having to process through the average human brain.

Human Data Overload Part I

by Jordan Spencer Cunningham on

The 21st-century world is perpetually flooded with more information and data than it can hold, and society is driven to consume as much of it as possible both in lieu of occupation and by choice. In the realm of technology, a computer can only process so much information at one time. Each device—from the simplest microwave to the most advanced supercomputer with dozens of nodes—has its limit of how much data can be pumped through its chips before it bottlenecks or even halts absolutely. So, too, the human psyche has its limits and will similarly degrade in productivity or even stall when confronted with too many stimuli and input. Its causes are various and widespread. It’s not just a personal problem; when an individual suffers, so does everything around him: his family, friends, work, social tendencies, and other devotions. With too many points of focus, no points will receive adequate attention.

Phone Call Fit for a Dog

by Jordan Spencer Cunningham on

I recently filled out some junk online forms with fake information using the name Julie Doggie, who is a real person and just so happens to be my dog. I made the mistake of using my Google Voice number for this junk form. The other day I received a call from a number in my local area code. After picking up and giving a greeting, I heard a lady ask, “May I speak with Julie?”

Carl’s Junior Now Peddles Porn Instead of Food, Still Prays Before Corporate Meetings

by Jordan Spencer Cunningham on

Have you ever read the plaques gracing the walls of most if not all Carl’s Junior restaurants? They’re the bronze ones depicting an image of Karl Karcher and his wife, Margaret, with a touching little epitaph about how wonderful they were. Did you know that that’s a bunch of baloney? That is, CKE Enterprises, the parent company of Carl’s Junior, put those up in an effort to make themselves look more like human beings than money-hungry charlatans, and they don’t believe a word of what they said. CKE Enterprises would hate their founder if he were alive today. They’ll probably rename the “Famous Star” to the “Porn Star” just to rub it in.[Read further…]
