Peak oil →

We can see that PPUE for most regions peaked around 2000. The big exceptions being Canada in 1992 and Europe and Africa in the mid 2000s. What this means for the majority of the world is that in little over ten years the average number of barrels of oil a single rig produces has almost halved. Put another way oil companies have had to double the number of rigs in operation just to maintain oil production at 2000 levels. This is the very definition of drilling faster just to stay still.

One way to gauge the cost/effort of producing oil is via Production Per Unit Effort (PPUE).

“Peak oil” is not simply about the quantity of oil being produced; it is about the cost/effort of producing oil. For most of the history of petroleum production, the cost/effort was decreasing or steady. But now the cost/effort is increasing; That’s an inflection of the second derivative of the cost/effort versus production relationship.

Everyone wants his parent’s, or friend’s, or partner’s undivided attention — even if many of us, especially children, are getting used to far less. Simone Weil wrote, “Attention is the rarest and purest form of generosity.” By this definition, our relationships to the world, and to one another, and to ourselves, are becoming increasingly miserly.

The key is to use technology in ways that enrich your life, save you time, open new horizons or make new accomplishments possible; Not to simply distract yourself from your life. It’s that simple.

I blog, therefore I am?

No, the initial impetus was to find a place to permanently – or as permanently as the Internet offers – publish my father’s eulogy: In Memoriam. I started piling on things I thought were interesting, fun, or poignant. I wrote some wall-of-text email messages – actual writing with references and original ideas – in response to Aikido questions, and the blog split into the Scree and Aikido tags. Later, I was toying with the idea of organizing a network and system administration group in the Lehigh Valley, wrote a few things about that, and the blog grew… “Feed me Seymore!” …and grew…

What I didn’t expect was that the blog would become a “read more…” link for my brain. Someone says, “that’s interesting,” or “where did you read/hear/learn that?” …and I go,

Yeah, uh… it was on that web site, the one with the words… Wait, just go to my blog and hit the search box . . .

The Chaos

Dearest creature in creation
Studying English pronunciation,
    I will teach you in my verse
    Sounds like corpse, corps, horse and worse.

I will keep you, Susy, busy,
Make your head with heat grow dizzy;
    Tear in eye, your dress you’ll tear;
    Queer, fair seer, hear my prayer.

Pray, console your loving poet,
Make my coat look new, dear, sew it!
    Just compare heart, hear and heard,
    Dies and diet, lord and word.

~ Gerard Nolst Trenité (1870-1946) from, The Chaos – Wikipedia

Welcome to the surveillance state →

Published June 25, 2013  ·  All posts on Jun 25

The Internet is a surveillance state. Whether we admit it to ourselves or not, and whether we like it or not, we’re being tracked all the time. Google tracks us, both on its pages and on other pages it has access to. Facebook does the same; it even tracks non-Facebook users. Apple tracks us on our iPhones and iPads. One reporter used a tool called Collusion to track who was tracking him; 105 companies tracked his Internet use during one 36-hour period.

…and he wrote that essay before the Snowden/NSA revelation showed us we’ve gone far beyond it being only an Internet surveillance state. We have collectively delivered ourselves into the power of ideas we do not know we have accepted.

SOLID object-oriented design →

Published June 23, 2013  ·  All posts on Jun 23  ·  

Five basic principles of object-oriented design. Not the only five, but five which are, well, SOLID.

Single responsibility – A class should have only a single responsibility.

Open/closed – Open for extension; Closed to modification.

Liskov substitution – Objects can be replaced by instances of their sub-types without breakage or surprise.

Interface segregation – Many, specific interfaces – that is, APIs – are better than fewer, more general-purpose interfaces. (…or “interface” in the worst case.)

Dependency inversion – Depend upon the abstraction. (Not upon the specific concretion.)
