chaosbutters··on US Army deploys its first floating solar array
well, luckily for the US, we have massive hydro power dams in the west that are low because of 20 years of drought, so we can actually do pumped storage.

Ideally, we would pump salt water from oceans to the salt water reservoirs and use surplus energy to desalinate to refill the fresh water ones.

chaosbutters··on Xerox PARC’s engineers on how they invented the future and Xerox lost it (1985)
I work at PARC, and I hard disagree. My "CEO" of our division is an impressive salesman that just had everyone at our conference coming to our booth.
chaosbutters··on Xerox Alto Emulator
I work at xerox PARC and we do IoT. Another group does 3d printing and others are doing various types of engineering and ai/ml.
chaosbutters··on Instagram Killed the Tabloid Star
scrolling through the news on different subreddits is quite fun and informative. Quick and easy way to get caught up on local and world news, sports, politics, etc. So all scrolling isn't bad
chaosbutters··on AMD Ryzen Threadripper 3960X and 3970X Review
probably closer to 3500-4000 USD. Maybe $5k if theyre feeling greedy. But I think they want to undercut intel so theyll keep their margins reasonable so they can crush the Xeon line
chaosbutters··on AMD Ryzen 9 3950X Review
I'm waiting for 64 core CPU. 32 is nice but still not enough.
chaosbutters··on Bank of America's CEO says it's saved $2B per year by building its own cloud
our internal cloud requires months in advance to get changes done :(
chaosbutters··on California’s new law bans schools from starting before 8am
should've slept during school like the pros ;)
chaosbutters··on Strengthening Congressional Independence from Corporate Lobbyists
isn't this the purpose of FFRDCs like Mitre?
chaosbutters··on Pi-Hole 4.3.2
thank you!
chaosbutters··on Economists don’t understand much about the macroeconomy
agent based modeling where the probability of the agents' actions is dependent on actual economic data...

more realistic sim city (city skylines)

chaosbutters··on YouTube should stop recommending garbage videos to users
same boat. I get really good recommendations logged in but it is a dumpster fire if logged out
chaosbutters··on Keeping Tesla Roadsters Alive Is Serious Work
um, my Nissan got a windshield crack, I went to the dealership to get it fixed and they said run away. We [Nissan] will charge you ~$1000 and it might take the whole day while if you go to safelite, they'll do it in 2 hrs and <$300. I'm super thankful the sales clerk was nice and honest.

Windshields are the exception for car repair and you shouldn't have been going to toyota.

chaosbutters··on Trails of Wind: Data Visualization of the Architecture of Airport Runways
it'd be fun to drop this vector field on a graph (maybe a sphere's surface), interpolate between points, and then drop in particles and watch their streamlines.

so the flying spaghetti monster?
chaosbutters··on Texas Power Prices Briefly Surpass $9k Amid Scorching Heat
Doesn't it make sense then to send the power eastward while max generating it and then import power from the west later in the day when you need it? You could theoretically leverage the time differences and peak usage/generation. I understand there is losses in transmission but seems like a good juggling act
chaosbutters··on Netflix’s biggest bingers get hit with higher internet costs
I would say 5TB is reasonable. If a 4K movie is 100GB. then over 30 days is 3TB of usage. If 1 person per day watches a 4k movie and the household of ~1-5 people does other things as well, 5TB should be sufficient. I think that is a stretch and my gut says yeah, 1TB is good, but I already upload/download 10-20GB per day at work so 5TB seems more reasonable for an upper bound.

I can since I'm interviewing there. Below is what they sent to explain what they do.

chaosbutters··on One City Saved $5M by Routing School Buses with an Algorithm
idk about Boston, but in Florida, I walked ~1km to elementary school, 15 minute bus to middle school (11-13 yrs old), and then had a 40 km drive/bus to high school.

While if I had stayed and lived in michigan, I would have been 1km walk from elementary, middle, and high school. With a university 5km away.

It all depends on the US city and state and how that community developed/organized.

chaosbutters··on AMD EPYC processors come to Google, and to Google Cloud
I can answer this! So my work computers are 28, 32, and 96 physical cores each. And honestly, none of those are enough. I'd ideally have a very high clock speed 128 core desktop with a 1,000-10,000 compute cluster available with 10 gb/s internet speeds.

Now back to your question on why these are needed, parallelized simulations. I do computational fluid dynamics (CFD) for designing, fixing, troubleshooting, and optimizing processes and products. They solve large systems of equations that need many cores for meshing and solving and then we need high CPU/GPU core counts just to handle and process the data. In my case at least, the average industrial/manufacturing piece of equipment needs about 1000 cores to recreate as a digital twin due to the amount of multiphysics, complicated geometry, etc.

chaosbutters··on Berlin’s Popular Shopping Streets Will Go Car-Free
This is how I feel about Manhattan/NYC. It should be limited to taxis/uber, buses, garbage, ambulances, and delivery trucks. There should be large garages/parking lots that are free/cheap just north of it in the bronx and people can quickly commute in via a shuttle, bus or bike.
chaosbutters··on California farmers are planting solar panels as water supplies dry up
I think a dyson sphere would be great more for helping us prevent global warming than generating cost efficient electricity. Opening and closing the dyson sphere to control radiation flux would be a cool thing. We'd have planetary AC
chaosbutters··on On Costliest U.S. Warship Ever, Navy Can’t Get Munitions on Deck
should've gone with trebuchets for optimal performance
chaosbutters··on The poor can’t afford to follow public health advice
I share the same reasoning and why I personally, question a person in a position of management. Being overweight, fine. But being obese is just a lack of will power.

It is refreshing to see CEOs like Musk and Bezos work on their health as they became more successful.

chaosbutters··on The rise of remote working will continue
I work in an office but have to deal with multiple time zones 5 hours ahead in UK and 3 hours behind in Cali. Basically, I work in the morning for UK and night for west coast and take a long afternoon lunch, nap and workout.

that's a pretty low bar (know python and have a STEM phd)

same with lawn movers, the sounds and vibrations hurt kids. I couldn't stand using one until about 15 or 16.

chaosbutters··on Third-Biggest U.S. Coal Company Files for Bankruptcy
and that is why I didn't go into O&G as a ChemE after graduating. The writing was on the wall with Iraq, Tesla, renewable installations, climate change, etc
chaosbutters··on Is Conference Room Air Making Us Dumber?
indoor plants would provide humidity and some co2 decrease (not sure how much)
