<p>I went to school for industrial engineering and have worked in manufacturing the last decade or so.<p>Bus production would be an entire refactoring of an auto factory. Tons of equipment would need to move around, electrical conduit would need to be re-run to different places, much of the existing equipment would be too small. The equipment would need to be ordered from suppliers who already have the next couple months to years of business booked, new suppliers sourced and contracts signed, etc. On an American timeline, I can't imagine it being done in under a year if you threw money at every problem aggressively.<p>We did change some auto plants to manufacturing airplanes and airplane components for WWII, but there was a lot more human labor involved, manufacturing tolerances were more loose, and we had widespread support of the American public to do what we needed to make things happen. It'd be incredible to see the War Powers Act implemented to publicly fund bus transportation, but I cannot fathom that occurring with this administration.</p>

<p>This reminds me of a neat piece of computer keyboard -> audio software I found on what had to be an "old internet" site 15-20 years ago.  For lack of a better phrase, it was relative tone keyboard.  I've looked but have not been able to find the software, not remembering any hint of the name, but it was fun to play with.<p>It worked one of two ways, I'm not positive which.<p>--------<p>You stared with musical note C.  One note could be played at a time.  G would go down a half note, H up a half note.  F down a whole note, J up a whole note.  Repeatedly pressing G would go down the chromatic scale.  Playing a Diatonic scale up would be a combination of pressing H and J.<p>--------<p>Pretend the keyboard letter G is the base note, mapped to C in music.  F would give a half note lower, H a half note higher, and so on across the home row of the keyboard.  Then you could adjust the base note (perhaps T to go down a half note, Y to go up a half note).<p>In essence, you could transpose a song from the key of C to D by doing a modifier, and your fingers could complete the exact same sequence.  In a jazz application, something on Spiral Synth like "FSA, GDS, HFD, K" might have been</p>

<p>What struck me about the big island is that it has 8 of the 13 climate zones, and you can go around the perimeter of the island in about 5 hours.<p>I loved going up Mauna Kea visitor center and stargazing.  At ~11,000 feet, it's one of the best places in the world for naked eye stargazing.  You're literally above the clouds, the island has strict rules about exterior lights at night to minimize light pollution, and you're above the thickest air.  I wasn't expecting to see the Milky Way so easily.<p><a href="https://en.wikipedia.org/wiki/Milky_Way#/media/File:Milky_Way_Night_Sky_Black_Rock_Desert_Nevada.jpg" rel="nofollow">https://en.wikipedia.org/wiki/Milky_Way#/media/File:Milky_Wa...</a></p>

<p>I worked with some supply chain consultants who mentioned "internal suppliers are often worse suppliers than external".<p>Their point was that service levels are often not as stringently tracked, SLA's become internal money shuffling, but the company as a whole paid the price in lower output/profit. The internal partner being the default allows an amount of complacency, and if you shopped around for a comparable level of service to what's being provided, you can often find it for a better price.</p>

<p>>This is one of the reasons I am so skeptical of the current AI hype cycle. There are boring, well-behaved classical solutions for many of the use-cases where fancy ML is pushed today.<p>In 2013 my statistics professor warned that once we are in the real world, "people will come up to you trying to sell fancy machine learning models for big money, though the simple truth is that many problems can be solved better by applying straightforward statistical methods".<p>There has always been the ML hype, but the last couple years are a whole different level.</p>

<p>I graduated in 2011. Smart phones were rare, but dumb phones were quite common.<p>The lunch room was quite loud. To keep people from being in their own world on their phones too much, my lunch table had a rule that if you laugh out loud at something on your phone, you had to share it with the table. It was quite effective, though somewhat embarrassing from time to time.</p>

<p>It varies significantly by locale. I've seen people post online about how it made little sense to keep just one gas appliance because of significant savings. I'm in Iowa, which typically heats on natural gas in urban areas. I have a natural gas central furnace and water heater. My clothes dryer is electric, and I have a 3 head heat pump which I use for comfort in a couple rooms. The house is an early 2000's standard builder-grade home.<p>For September, $12.31 of my $27.01 gas bill was variable based on my consumption.<p>In December, $84.82 out of my $99.65 total was consumption driven.<p>I've run numbers on whether it'd make financial sense to go electric for heating, and the break even point is in the 30-40 degree vicinity. With temperatures 20 and under a healthy chunk of the year, unfortunately the added expense doesn't make financial sense.</p>

<p>I work in manufacturing. There are a few instances where watching YouTube may not be a huge hazard, but 98% of the roles I've seen the are reasonable reasons to not permit that. If nothing else, it'd be easy to let quality suffer which causes many bigger headaches.<p>I went to a panel discussion at a conference last year. Operations managers agreed labor was their biggest challenge. The manager for the promotional materials company who was probably around 60 discussed how he has loosened up a bit the last ~15 years. If someone sends a couple texts and it slightly impacts the units they (personally) do per hour, it was better than being super strict and losing employees. He had to adapt because the mentality was far different than when he started in the workforce.</p>
