What’s Actually Happening When You Talk to ChatGPT?: How LLMs (Large Language Models) Actually Work, Explained Simply
Okay so you’ve used ChatGPT, or Claude, or whatever chatbot your company just made you download. And at some point you’ve probably wondered…what IS this thing actually doing?? Is it thinking? Is it googling stuff behind the scenes? (Unless you’re using a search-enabled feature, nope!) Is there some giant database somewhere with every answer already written down? Nope. Let’s break this down. What is an LLM, really? A large language model predicts the next word. One word at a time. Based on patterns it picked up from a truly absurd amount of text. That’s it. That’s the whole trick!! Everything else you’ve seen it do — writing paragraphs, spitting out…

Using Spanish as a Cheat Code for Italian: Cognate Patterns That Actually Work
Learning a third or fourth language gets easier — not because you get smarter, but because you stop starting from zero. I’m fluent in Spanish, conversational in French, and currently building Italian. Every time, the fastest gains come from hunting for overlap before I even open a vocab list. This is that overlap, laid out the way I wish someone had handed it to me on day one. A working map of where these languages line up, and where they don’t. Why Spanish helps with Italian at all Spanish, French, Italian, Portuguese, and Romanian all descend from Latin, specifically Vulgar Latin, with the word “vulgar” coming from vulgaris, meaning “of…

Metaverse security is a thing because security is still a thing…
With all this talk about the metaverse and Web3.0, it’s easy (always too easy it seems) for security to become an afterthought, instead of a before-thought, or even a during-thought. So, please. Let’s discuss METAVERSE SECURITY. Even if you still have no idea what the metaverse is or what the “Web 3.0/Web3” is, you must understand that being online on the Internet exposes you much like you are exposed the very moment you leave your house. Once you leave the domain and sanctuary of one’s home, we are exposed and take measures to mitigate risks and privacy. We wear clothing to protect us, yes, and also to shield our most…

What is a password manager and why do you need one…
I was speaking to a contact who is studying the cybersecurity industry and does not use a password manager. Interestingly enough, it’s actually a debate I’ve seen crop up a few times in cybersecurity circles. A password manager is an application to help your store and manage all the various usernames, passwords, URLs, what have you…that all come as a byproduct of the digital terrain that we are increasing surround by. I used to think “But MY password is unique! It’s not “password” or any of the typically mocked but often used, much maligned, stereotypical passwords. Oh, no. Mine was different and unique. And there are people who do this…

What Is The Metaverse?
The term “metaverse” is a word that has been around for decades but has recently been thrust into the broader spotlight, and is thus having it’s moment of media spotlight glory. The term “metaverse” is rooted in sci-fi literature by general consensus of, well, almost everyone. However, the term blasted into mainstream consciousness this past year, especially over the summer with Facebook announcing the beginnings of its own metaverse push, and further digging in recently with a full rebranding to Meta, A Social Technology Company amid the current turmoil in regards The Wall Street Journal’s “Facebook Files” investigation of whistleblower Francis Haugen.

FAA Plans Warnings on 5G…What 5G Means for the FAA, FCC and Air-safety…
FAA Plans Warnings to Pilots, Airlines Over New 5G Rollout… Air-safety regulators tussle with telecom regulators over safety concerns ahead of expansion of new wireless technology planned in December. “At the heart of the dispute is the U.S. rollout of 5G. Short for fifth-generation wireless, 5G technology offers internet speeds 100 times faster than today’s 4G service, potentially paving the way for new applications, revenue and jobs.” “To offer 5G, telecom companies need more space on the airwaves. Wireless spectrum is like land, in that the number of available frequencies is finite. The FAA-FCC clash is just the latest in a series of dis- putes between U.S. govern- ment agencies…

Amazon’s “Sidewalk” Mesh Network Goes Live; All Devices Are Opted-In Automatically By Default
Amazon’s neighborhood mesh network dubbed “Sidewalk” has gone live. Via the New York Times: On June 8, Amazon is set to flip the switch on its new free service called Sidewalk, which will automatically be enabled on many of Amazon’s Echo smart speakers and smart displays, as well as some Ring devices (for more details, see the complete list of compatible devices). Once Sidewalk goes live, compatible devices such as speakers, light bulbs, locks, and sensors will be able to connect anonymously to other Sidewalk devices to borrow a little slice of internet connectivity. That should enable some interesting features down the line as more compatible devices appear. It’s also creating a fair amount of…

How Was Colonial Pipeline Hacked/Breached? Because of One Single Employee’s Compromised Password
That’s all it takes, and usually what it comes down to. Passwords. As the founding contemporary lyrical wordsmith members of Wu-Tang would say, “Protect ya neck!“. Because without it, you’ll lose your head. Same with passwords! Protect ya passwords!!! All a malicious actor would need is a password to an account, and just like that (*finger snap!*), you’ve invited them in, like welcoming Count Dracula through your front door for Sunday dinner. So, Colonial, right…here’s the latest. After an analysis of the cyberattack on Colonial Pipeline, investigators suspect that hackers obtained the password from the dark web (think a marketplace for illicit activity) where such info is available for the…
