learn_more··on My three-year-old has taught me the value of talking to strangers
Yep. I call it "computer brain". It's like the code for interacting with people gets swapped out to disk, and to speak with humans, you have to page that code back into memory.

It can take me an hour to come back to the world of the living.

learn_more··on Suicide rates are rising among U.S. nurses
> With stretched resources and the mental and physical toll of working through the pandemic, the study forebodes of the crisis nursing staff will face if steps aren’t taken to support their well-being.

Sounds like this journal is pandering to their audience.

learn_more··on Best practices for writing SQL queries
I'm the opposite. I like the short aliases, esp. when there are many tables. Short aliases can all be the same length, and therefore align better for better readability, and they don't pollute the visibility as overly-verbose table names do.

In code, I like the length of the variable name to be proportional to the size of the scope. Small scope -- short variable names.

FYI, your "pricing" link at the top of that pci.html page 404's. The pricing link works from other pages however.

Actions speak louder than words.

Only confident people mock themselves.

It's simple to try out by uploading a file via the web page at https://cimbar.org
learn_more··on Incandescent Gas Lantern Mantles (2009)
Just for scale, Americans receive about 620 mrem per year, mostly from radon in the air.

Germany's high costs are a result of their shift to "renewable power" sources.
learn_more··on 'Zoom towns' are exploding in the West
How are you planning to handle Internet access on the boat? Starlink being the ultimate solution is still probably years away for ocean coverage.
learn_more··on Charlie Chaplin Was Almost Assassinated in Japan to Start a War
What threats motivated the populists of the 1930s? What motivates them today? Were/are any of their concerns valid?

If you want better answers than "Japan jumped on board too", you must ask yourself those questions as well.

learn_more··on Tons of microplastic rain onto western US
I wonder how much the biofilm on the surface manages to prevent erosion of the substrate.
learn_more··on The Rise, Fall, and Rise of the Home Office
This is a decent chair. $236.54 currently.

much better than anything at Office Depot or similar stores.

learn_more··on The Rise, Fall, and Rise of the Home Office
Good acoustics (low echo) is high on my list, and one of the first things I improve when setting up my home offices.
learn_more··on Five surfers drown in the Netherlands, getting into 'avalanche-like' sea foam
A few feet of foam atop the water is all it would take to smother you because you can't breathe it nor get above it.
learn_more··on The Mayflower Autonomous Ship Project
I wonder how the Wave Glider deals with fouling of the umbilical from seaweed and fishing gear?
learn_more··on XB-1's wings are officially closed out
They mention having a portable ultrasonic device for "seeing" inside the wing.
learn_more··on Man who stockpiled hand sanitizer donates it all ahead of investigation
Unfortunately, such a company would be a lightning rod for the mob's ire as the downvotes to this comment so clearly illustrates.

learn_more··on Show HN: Map Based Chat
I created this for van dwellers, to help foster communication and possible in person meetups. We'll see how it goes. Suggestions are appreciated!
learn_more··on Gears
I had the same feeling, hoping to receive an epiphany, perhaps on the bevel of the gear teeth, but nope. Then I thought, ok, surely there's an insight to be gained regarding helical gears, but it was never discussed.

learn_more··on The Grand Unified Theory of Rogue Waves
Perhaps the density of the cargo is, on average, too low. The amount of ballast needed would make it impractical.

learn_more··on Starlink Is a Big Deal
With enough people in once place, Starlink will suffer from congestion just like a cellular network. I don't think it's fundamentally different in that regard. But great for boats indeed!
learn_more··on Ask HN: What interesting problems are you working on?
I'd like to know of a good book for the science of cooking. I hate blindly following recipes.

Like a poor man's version of this book by Microsoft CTO Nathan Myhrvold.

learn_more··on Teens don't have a clue about IT? (2016)
Jonny can't troubleshoot.
learn_more··on Why we fall for cons
Another explanation would be "assumed due diligence".

It's the assumption that someone else has already confirmed the veracity of the situation. Once the "officer" had the first group of dupes in tow, he appeared legitimate to the second and third groups of people he encountered.

Using this approach, you parley the deception of each subsequent group of people into one spectacular overall ruse.

learn_more··on Energy Breakthrough could Store Solar Power for Decades
But there's something special about having a low-tech solution which isn't as likely to break, and doesn't require a genius to troubleshoot. As an engineer myself, I prefer a calmer, low-tech approach when possible.
learn_more··on Advanced Range Instrumentation Aircraft (2013)
Sounds like it works like an intercooler on a turbocharged car engine. It cools the intake charge to increase its density to cram more air into the combustion chamber.
learn_more··on The richest families in Florence in 1427 are still the richest (2016)
"When regressing the pseudo-descendant’s earnings on pseudo-ancestor’s earnings, the results are surprising: the long-run earnings elasticity is positive, statistically significant, and equals about 0.04. Stated differently, being the descendants of the Bernardi family (at the 90th percentile of earnings distribution in 1427) instead of the Grasso family (10th percentile of the same distribution) would entail a 5% increase in earnings among current taxpayers (after adjusting for age and gender)."

So if your family was rich then, you probably make 5% more than than most people now. Nothing much to see here.
