Who was Harry Nyquist?

Dear Members and constituents,
Ever wonder why a T-1 has 1,536 Kilobits per second of capacity? Why not a round number? Even if you were to use Kilobytes per second you'd come up with 192 KB per second. In case you were wondering, it all comes down to the dawn of digital voice communications. In order to reconstruct a sound, the samples taken can be no less than half of the frequency of the sound we are trying to represent. In normal conversation the human voice seldom exceeds 16 KHz and therefore sampling it 8,000 times per second would be sufficient for both sides to understand each other. They also decided 256 levels (8 bits) per sample provided sufficient information. Of course 8,000 samples per second at 8 bits per sample provide us with 64,000 bits per second, the bandwidth of a phone call. That is, of course, why your voice on a phone conversation sounds a little "tinny" and does not have quite the quality of, say, a CD. You take 24 of these together and, voilĂ , you have a DS-1.


Lately I have been wondering what the energy capacity of a dozen donuts is and how you would express it. I like the idea of expressing it in Kilobites, however that would probably be a measure of how filling a dozen donuts is, not exactly a measure of energy potential. I'm sure you coud take the mass of each donut and multiply it by the calories per mass unit and then add it up… then again, perhaps some things are better left unquantified. Speaking of quantities, due to their reputation for having a smaller size, Mr. Bagnato has proactively brought in five dozen Krispy Kreme dounts. In looking at the selection he made for this his debut, I think we can expect many good Fridays from Jim.


Happy Friday!

Remote Donuts

Friends, I knew working from home was going to be weird, so I had mentally prepared for some of the inevitable challenges. I decided to keep as many personal routines as possible intact . I’ve been getting-up at the same time (even though it is tempting to sleep-in due to the shorter “commute”) and have kept-up with personal grooming (showering, dressing for work, having breakfast, etc.). I got a nice desk and dedicated ergonomic space and brew a pot of coffee every morning. As for the isolation, I suppose it can’t be helped. Sure, video meetings are nice, but they can’t take the place of hallway conversations. On whole I’d say my first week working from home has been a guarded success. Still, there were a few unexpected twists. Fresh air. On Wednesday afternoon I realized I had not set foot outside my house since Sunday –and quickly remedied the situation. Invisible chair. The edge of my camera view catches a corner of the room with some “invisible” clutter. As it …

Donuts, here for your safety!

Friends, This week I discovered our Denver North office has a Bitcoin Teller Machine (BTM). What?!? A convenient way to cash-out on all your Bitcoin millions before the hype wears-off. Except, this teller only TAKES your hard-earned dollars and converts them to Bitcoin. It does not DISPENSE hard currency. What’s the use case for that? Never mind, duh! It’s the general scenario that will ensure Bitcoin never goes to zero (despite recent trends). Crime! Say you are a crime boss (or petty criminal) who wishes not to have your transactions traced. An anonymized crypto-currency is the perfect vehicle to contract for that hit job, buy and sell stolen goods or funnel your monies far from prying eyes. But what if your cash business still accepts, well, cash? What do you do with all that clunky paper? Depositing it at your bank so you can buy your crypto online defeats the whole scheme. Enter the BTM. First you rent some office space at Spaces (which, by the way, makes for a great front). The…

Family and Friends

Friends,
I’m trying to maximize the time I spend with friends and family while in Ecuador. My dad had nine siblings, my wife’s dad 15. As you might imagine, my cousins and their families are fairly numerous (despite the fact five of my dad’s brothers didn’t marry or have children). Then there’s my wife’s family and my childhood friends. Needless to say, there is never enough time to see everyone, despite a valiant effort. Of course, I’m also working from “home”. Corny as it may sound, working half a world away, I realize I miss my Windstream “family” and I look forward to seeing you soon. In the meantime, there are donuts, here today courtesy of John Huddleston.  So, enjoy some comfort food with regards from my Cuenca family (pictured) to you!
