Biking Yinz-ward, Part 2: In Which Matters of the Hamstring Are Considered, Narcissism Cross Technology Debated, And School Bus Induced Time Portals Propositioned

Here’s Part 1 if you missed it.

13. Turn right onto the Lower Trail

(Estimated) Time: 8:05 a.m. Time from start (5:49 a.m.): 2 hours 16 minutes Miles this step: 12.8 Miles total: 39.2

Comments: Picture!

The Lower Trail may be the finest piece of land I’ve had the pleasure of crossing. As the map shows it travels along the Juniata River; what it doesn’t show is the flush shades of green,…

Bitwise operation: One that operates on bit patterns or binary numerals at the individual bit level. These may be one of the fastest processor operations, beating division, multiplication and sometimes addition, and using fewer resources as well. (This difference is reduced in modern processors.)

Common bitwise operators include NOT (complement), a unary operation that…

Recently I watched Finding Vivian Maier in State College’s premier old-style theater, The State Theatre. (They even spell it all hoity-toity.) It told the story of Ms. Maier, a mid-1900s nanny whose hobby for photography went beyond all possible expectations of those who knew her. Her total work amounts to more than 100,000…

Biking Yinz-ward, Part 1 of Several

The best part about biking from State College, Pa. to Pittsburgh is people’s faces when I tell them.

The worst part was doing it.

That’s not a holistic condemnation of the trip. Getting to see a chunk of western Pennsylvania for the first time, following a long trail step-by-step, avoiding getting lost, meeting new people, and resting were some of the highlights I experienced. I wouldn’t want…

Data integrity: The condition of uncorrupted and retrievable data. The two rough categories are physical integrity – against which challenges include electromechanical faults, design flaws, material fatigue, corrosion, outages, and other environmental hazards – and logical integrity, concerning the correctness or rationality of a piece of data, such as its referential…

Truncate: Truncation means limiting the number of digits on the right side of the decimal point by discarding the least significant ones. The number itself depends but four digits is typical. More officially, the truncation error can be (up to) twice the maximum error in rounding. The most common truncation feature, or error, in programming occurs when a decimal number…

Album review below. It’s been awhile and I feel out of practice, so let’s do this. But first, the journal entry.

I’ve been meaning to write down some personal epigrams, idiosyncratic aphorisms, witty sophistications, and similar drivel of my thoughts. I figured I’d try out a few here. Feel free to improve them, though I warn you they have all been thought out for at least five minutes.
