Episode 97 — Next Hundred

hundredAdam, Brian, and Jeff discuss where the podcast should venture during its second hundred episodes.

  • Adam claims to be better at long term than short-term planning.
  • Listener feedback is encouraged as we try to sort out what topics to cover in upcoming episodes.
  • Tutorial episodes (for example, Nuts and Bolts) seem well-received, but require substantial advance planning. Additionally, there are limits to how “deep” we can dive with an audio podcast.
  • Podcasts that regularly dive into technical subjects include Pragmatic and Security Now.
  • Brian notes Dan Carlin’s voice, which can be heard on the Hardcore History podcast.
  • Jeff would like to see a steady stream of working engineers appear on the podcast during coming years.
  • “War stories” have benefited Brian during the course of his career.
  • Brian suggests using LinkedIn to reach potential guests for future episodes.
  • A possible new feature for the podcast would be coverage of current engineering events; say, the recent landing of the Blue Origin rocket.
  • One of the classic television “debate” shows was CNN’s Crossfire, which premiered in 1982.
  • While there are only 8 engineers in the current US Congress, there are 202 lawyers among the 435 Representatives and 100 Senators that make up that legislative body.
  • Jeff acknowledges his home state once came close to passing a law that would redefine the irrational number pi as being 3.2.
  • Adam notes that the degree of curvature is frequently used in civil engineering.
  • Vanity publishing has been around for many years, although it is much easier to be self-published these days.
  • We discuss a recent episode of The Amp Hour podcast where Chris and Dave answered live questions.
  • Brian insists we should avoid participating in “Hangout-a-thons.”
  • In recent episodes there hasn’t been much discussion of the trend toward shorter employment periods for engineers; Jeff wonders if this could provide an area of focus in the future.
  • Most people lose interest in new music after the age of 33.
  • Jeff has never been fond of disco music, especially the 1979 hit by Anita Ward, “Ring My Bell.” (YouTube)

Episode 96 — Perceptions

perceptionsThis episode of The Engineering Commons finds the gang discussing how engineers are perceived by those outside the engineering field.

  • Jeff accidentally reveals the plot of a well-known fairy tale, Rumpelstiltskin, while sharing a childhood recollection.
  • At the end of 1981, when Jeff graduated from college, inflation in the U.S. was around 10%, six-month certificates of deposit (CDs) were paying 13.1% interest, and 30-year mortgages carried a hefty 17% interest rate. He was happy to find a job (at any salary).
  • Between 1994 and the top of the dot-com bubble, Brian opines, it was a prevalent attitude that an engineering career could lead to significant wealth.
  • As of 2006, a third of S&P 500 CEOs had undergraduate engineering degrees, says Business Insider.
  • Jeff remembers working with secretaries who would type his hand-written memos onto company letterhead using a IBM Selectric typewriter.
  • As recently as 2011, there was but one engineer in the US Congress. However, there are currently seven engineers in the House of Representatives, and one engineer in the Senate (says a Congressional Research Service report).
  • From the “give-yourself-a-pat-on-the-back” category, Adam reminds us of the graph titled, This Chart Shows Just How Much Smarter Engineers Are Than Everyone Else.
  • We discuss whether engineers really are a “different breed.”
  • Carmen thinks the TV series Silicon Valley does a reasonable job of portraying engineers.
  • Episode 40 of this podcast, titled “Engineering Fiction,” discussed how engineers are depicted in today’s mass media.
  • It turns out that Bill Nye (the Science Guy), is a Mechanical Engineer who used to work for Boeing.
  • A common myth is that engineering school is difficult; in fact, it’s brutal.
  • Brian notes the difference in permanence between electrical and civil engineering projects.
  • A healthy number of engineering students graduate with the misconception that engineers work alone and need not follow directions.
  • A Mythbusters episode (#222) demonstrated that unassigned seating results in the fastest boarding time for a passenger plane, but also generates the least satisfaction among passengers.
  • With business casual attire the current norm, engineers don’t have to worry very often about the social significant of wearing a “red power tie.”
  • Carmen notes that our past episodes with Cherish Bauer-Reich and Sophi Kravitz may shed some light on additional stereotypes encountered by women entering the engineering field.

Episode 95 — Details

detailsBrian, Carmen and Jeff discuss the role of details in engineering projects, and how one goes about evaluating, managing, sharing, and documenting critical minutia.

  • In the introduction, Jeff misses the detail that this podcast is published in November, not October.
  • Carmen doesn’t mind sweating the details, but reviewing documentation for typographical errors is not his favorite task.
  • It is often said that “the devil is in the details.”
  • We continue to look for guest and topic suggestions from our listeners, so feel free to send us a note with your ideas.
  • A previous guest, James Trevelyan, has written about the value of engineers, and how uncertainty reduction is an important contribution of the engineering profession.
  • Uncertainty is frequently treated as a statistical issue.
  • Brian relates a recent situation in which he burned through many hours trying to uncover a programming detail buried in the documentation.
  • Electronic circuits can behave badly in “high EMI” environments, where EMI stands for “electromagnetic interference.”
  • Jeff justifies his “pi multiplier” concept (see this podcast’s first episode) with the “cone of uncertainty” used by software developers.
  • It’s Brian’s opinion that engineers often fail to utilize the formal methods found in other professions when managing a multitude of critical details.
  • Jeff claims that engineering standards ease the burden of dealing with frequently encountered details.
  • Of course, as Carmen observes, the problem sometimes lies in choosing the “right” standard.
  • Searching a large solution space for potential design details can be a frustratingly slow process, says Jeff.
  • Brian always tries to have a backup plan, so he is not “checkmated” by a single detail.
  • The amount of documentation appropriate for each detail seems related to the detail’s expected and potential costs.
  • Creating a documentation hierarchy can provide needed information without overwhelming customers, notes Carmen.
  • Humans quickly become inured to a surplus of details (or warnings).
  • Brian has found modularization (it’s really a word!) to be a good means for keeping details from interfering with one another during the development process.
  • Software packages are available for companies wishing to implement enterprise resource planning (ERP).
  • Git has become very popular as a version control system.
  • Hardware changes can be tracked in Git using visual diffs.
