Absolutely stunning to this fat old white guy injineer.

(I knew a lot of this but never saw it so well explained. 

Reminds me of the great economics text “I, pencil” and the various adaptions of it.

How much we stand on the shoulders of our predecessors and their intellectual discoveries and capital investments.

INTERESTING: Mushrooms to bricks like the Bible’s straw into bricks

MYCELIA + SAWDUST = HOUSE?
Michael Uttmark March 5, 2017

*** begin quote ***

Take a guess. What is the featured picture for this article? If you’re channeling your inner Google image recognition, you might say: “Best guess for this image: rock.” But, like Google, you’d be wrong. Instead, what you see are bricks made out of fungi obtained from tissues of mycelia.

By taking fungi obtained from tissues of mycelia and storing them in a jar filled with a growth medium (usually sawdust), MycoWorks is creating all sorts of materials with exciting properties. In just three to seven days, the fungi and sawdust mixture expands and forms into clumps of material, which are then used to create products like handbags, purses, bricks, you name it. According to co-founder Phil Ross, “production of this material is similar to making ravioli from scratch, and the final product is more resilient than concrete.”

*** end quote ***

Wow, just look at the video, it’s extremely impressive. 

A building material that won’t break in an earthquake!

A simply stunning idea.

Like that college professor who reengineered plywood to make it “bullet proof” (actually flying debris proof; think the movie “Twister”), this could revolutionize the home / office building meme — fireproof and earthquake proof buildings?

Ahh, to be a young injineer again with these “paints” on your “palette”!

INTERESTING: Talking about !

Let’s talk crap. Seriously.
By Dan Dennett

*** begin quote ***

Sometimes mentioning the unmentionable is a major step forward. Rose George’s witty, fact-filled talk about the problems we can solve if only we start taking shit seriously is just such a step. Human excrement is not just a major source of disease; it also can be a source of remarkably effective medical treatments, and of energy. Putting poop where it can do good rather than harm is surprisingly easy and inexpensive once we clear away the myths and taboos.

It’s often said that water will be in the 21st century what oil was in the 20th century, and among the most effective ways of preserving and enlarging freshwater supplies worldwide are revolutions in how we dispose of our excrement. It’s mainly social attitudes that stand in the way of adoption of these practices and systems. So here’s a great opportunity for social activists to participate in the meme-spreading that could wipe out the shit-spreading that’s fouling the environment. Don’t preach, don’t teach; reach out, in the ways Rose suggests.

*** end quote ***

When I was a young fat old white guy injineer, there were a lot of jokes about “sanitary engineering”, but we learned how essential it is to human survival.

It’s sad that some MANY children die from “easily” preventable causes.

Argh!

What3Words digital addresses spread to island nations
For countries with missing or broken postal address systems, assigning three-word labels to every geographic spot on the planet can be useful.

*** begin quote ***

But it’s not perfect: You need a phone or computer to translate the three words into a physical location, there’s no What3Words support in popular navigation tools like Google Maps, and adjacent patches have totally unrelated names so you can’t tell what country a three-word label is in, much less what neighborhood.

*** end quote ***

There’s no doubt to any reader here that I LOVE this idea.

All that’s needed it that (1) Google get behind it; (2) the adjoining “words” be know on the map; and (3) the Gooferments of the world get behind it.

Amazon, Walmart, and most post offices could save time, money, and confusion with it.

FROM “dinner.sizes.chat”, see you soon.

INTERESTING: NFL suggestions

Tuesday, February 7, 2017
NFL suggestions —
  • Depoliticize
  • Eliminate the psuedo patriotism
  • Lower the prices
  • Shorten the games
  • Start night games earlier (I have a bedtime)
  • Innovate the challenge system (Need them to get the calls right.)
  • Not every stoppage in play is not a time for 2 minutes of commericals
  • Prohibit “repetitious” commercials. (Same product or service ok; just need a different commercial for it. Repetition leads to “tune out”)
  • Less talking heads; more action.
  • Less pre-game and post-game
  • Fewer meaning less games
  • A “mercy rule” for the fans — down 40-3 in the last quarter; games over. (maybe first to 50 points)
  • Overtime needs to go until there’s a win. (Ties are like kissing your sister.)
  • Stop demeaning women by giving them meaningless on air on field “interviews”. 
Argh!

A New Playbook 
The NFL is searching for new ways to tighten its grip on the public’s attention. Ahead of Sunday’s championship matchup between the New England Patriots and Atlanta Falcons, NFL Commissioner Roger Goodell on Wednesday plans to use his annual state-of-the-game press conference to stress that the league is serious about making changes amid steep ratings declines and other problems. The NFL has begun experimenting with shuffling the way ads appear in game broadcasts, and is considering making the weekly lineup of games easier to find on television as well as tweaking the pace of the sport itself. The move to shake things up comes after a season in which average viewership per game fell 8% overall and some teams played before ugly patches of empty seats in stadiums as sold tickets went unused.

INTERESTING: Were those Samsung smartphone batteries UL certified?

Monday, January 30, 2017

from the Wall Street Journal

*** begin quote ***

A Sorry Mess 
Samsung is on an apology tour for the blunder that led to the costly and embarrassing recall of 2.5 million smartphones. After four months of testing more than 200,000 phones, Samsung concluded that its flagship Galaxy Note 7 caught fire because of bad batteries—two separate sets of bad batteries made by two different companies, in fact, a conclusion also reached by independent certification firm UL. Our technology columnists, Geoffrey A. Fowler and Joanna Stern, compare it to “a meteor striking your house—twice.” Samsung said it would implement new safety measures, including an eight-step battery-safety check, for future devices. Fowler and Stern give Samsung’s response thus far a C grade, stating that it is still unclear whether the new tests raise the bar on safety or merely match what other premium smartphone makers are doing.

Were those batteries UL certified?

That’s my only question since UL certification is the “gold standard” of safety.

INTERESTING: Am I being to “Law & Order” paranoid?

Wednesday, January 25, 2017

An interesting thing happened to me the other day when I was driving up to The Free State of New Hampshire https://freestateproject.org/ from the Pepuls Republik of Nu Jerzee!

I stopped for dinner at a local diner along the way. After parking, this driver starts choking the horn at me. WTH. So I walk over, and this old biddie is yelling “Directions. I need directions.” and starts to ask me local geography questions — what road is this, where is deerfield, is this route something or other. I thought I was on Jeopardy finally but she was no Alex Trebeck.

So, I said “OK. First calm down. Close your door. Lock it. And roll down the window.”

It took her at least two minutes to do that. I said: “OK, I’ll help you but never open your door around strangers. What is the problem?”  

She was still agitated. But I got the story she was lost, she got off at the wrong exit, and didn’t know how to get home. 

Wow, that’s easy. 

I told her to wait in her car while I got my phone. Which I did. I had the WAZE app up like I always do for traffic and police alerts. 

So, I asked her address. She gave it to me and it was about two miles away.

I showed her the map, and then I went over the turn by turn. She was still confused. 

I could see that this was not going to end well if I just sent her off into the night. So I said, “OK, just follow me. I’ll lead you home.”

Got in my car, turned around, and led her home.

10 minutes away. (She obviously turned the wrong way off I91 and got confused.)

Led her to her house. Without getting out of my car — window to window — confirmed she knew where she lived. Waited while she pulled in and went into the house.

Went back to the diner and had some very dry “bad” meatloaf. And thought about the incident.

LESSONS LEARNED (Maybe I watch to much Law & Order)

  • She trusted fate. I could have been a “bad guy”.
  • I trusted fate. She could have been a “bad guy”. (Pretty random chance.)
  • There could have been Unintended Consequences of my good deed.

NEXT TIME

  • Alert one of my “shadows” that I am deviating from plan.
  • Photo and share her plate number.
  • Notify the police about what’s happening. Have them schedule a “welfare check”. I probably need to give them my plate number if I knew it.
  • Confirm with my “shadows” that I am back on plan. 

Does that sound reasonable or am I being to “Law & Order” paranoid?
