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!

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!

Donuts and Space-Time

Friends,
Have you ever stopped to consider the profound (and sometimes unforeseen) impact our actions can have on the fabric of the universe? The thought occurred to me as I was watching Pablo, my 6 foot something fourteen-year-old son. He is a smart, likeable, independent young man who is starting to assert his personal tastes (big Afro) and will, sooner than you know it, be an adult -fully in charge of his own destiny. If you rewind just a little, it was not so long ago he was that "I'm cute and I know it" six-year-old, small enough to sit on daddy's lap, sporting a hairstyle to daddy's liking. Rewind a little further and he was a twinkle in his daddy's eye. A decision waiting to be made. An action ready to be taken. Pure potential. Today, I can’t imagine life without him (or any of my other kids). Back then, I couldn’t imagine how much he would enrich my life. The same can be said for so many decisions. Enrolling in University, starting a new project, maki…

Muffins and Covfefe

Friends, I’m surprised that none of those trolling POTUS over the Covfefe tweet have suggested an acronym-related explanation. After all, he is the commander in chief, and much like telecom, the military is replete with acronyms and abbreviations. Here are some plausible explanations. ·A new top secret chemical weapon, inadvertently referenced due to an innate desire to Brag –it would explain the ensuing “oops” silence. Referenced by its chemical elements: Cobalt Vanadium di-Iron (CoVFeFe or CoVFe2). ·He may have been talking about the border wall: Concrete Obstacle Visioned to Forcefully Exclude Foreign Entry ·It could be that he was contemplating a new shorthand that packs a high concentration of superlatives. Charming Outrageously Very Fabulous Extremely Fantastic Eyepopping (which could be followed by any noun) ·It’s possible he was explaining the rationale for leaving the Paris accord: Climate Optimistic Views Fiercely Avoiding Factual Evidence ·It could also be a new telecom techno…
