karlh··on Poll: Should submissions about Elon Musk's political actions be allowed on HN?
I think it should be allowed. His actions often have significant impacts on tech and he seems to be expanding his reach by taking control of government spending science funding.
karlh··on Ask HN: What are examples of shared spreadsheets you use (if public link it)?
My wife and I share google sheets for grocery list. When one of us notices something we need we can add it and whoever goes to the store can get it.

Additional sheets contain lists of reference info, the size furnace filter we need, the model number of the filter for our water system, etc, to help us get the right one for stuff that isn't purchased much.

karlh··on Ask HN: What is it like to be old? What advice would you give to younger people?
Good point. But really, all advice from older persons to younger persons carries a strong element of survivorship bias. The data are biased but RCT studies are not practical so it's reasonable to use what we have (recognizing the limitations of our data, as you pointed out).
karlh··on Ask HN: How do you stay informed without social media?
What makes you think social media keeps you informed? (Honest question)
karlh··on 57 Buffalo Police Resign from Riot Unit in Protest of Officers' Suspension
To me, the appalling part was not the shove, it was likely unnecessary but I do not think the officer intended to put him in the hospital. The appalling part is the deliberate lack of any help once he was down and obviously seriously injured. An officer who started to help was dragged away by his colleague. These officers did not live up to their oath and duty, not because he was shoved but because he was abandoned instead of receiving first aid. The fact that "EMTs are coming" does not relieve one of a responsibility to help an injured person. That is pathetic.

And certainly badRNG is correct that "I vas chust followink orders" is a very bad look. In addition, I doubt the orders were to leave seriously injured fellow-citizens bleeding on the ground.

karlh··on Ask HN: Why is everyone I talk to in the real world so unperturbed by Covid-19?
As I understand it, the difference from flu is that it's much, much more contagious. 10 pct hospitalized is very different if there are 100,000 cases vs 100,000,000. There are roughly a million hospital beds in the U.S., I dont know how many ventilators but a lot less. The healthcare system could be easily buried if we can't "flatten the curve". The same number of people, roughly, will get sick, just not as many at a time.
karlh··on Groundbreaking Study Shows Shielding EMF Improves Autoimmune Disease in 90%
This article looks like nonsense. The idea that the silver-threaded garments seemed so credible that use of a control group was deemed unethical, for example, is silly. This appears to be pseudoscientific blather.
karlh··on Study in mice explains how brain can turn pain signals up or down
Just as interesting is the role of culture on pain experience. I believe I recall a study some years ago that showed differences in pain experience across different countries/cultures. Immigrants to a new culture continued to show response patterns consistent with culture of origin. Their offspring responded more like the new culture and more so over several generations. I wish I could recall the research but it's been a while. Pain, especially chronic pain (which is very different from acute pain) often presents very similarly to an anxiety disorder.
karlh··on Murder by Rifle vs. Death by Meteor
Interesting. A bit over 20,000 people complete suicide by firearm in the U.S. per year (https://www.cdc.gov/nchs/fastats/suicide.htm). Where did FBI find over 50,000 annual bare-hands-or-feet deaths?
karlh··on Dumping Unit Tests
You mention removing "most" unit tests from the app, not all of them. Does that mean that you find some of them valuable and some not? This might suggest that perhaps you feel like you are maintaining too many unit tests, a little different perspective than dumping them all. Adapting to a more effective/useful/manageable amount of unit testing seems like a reasonable goal.
karlh··on NASA engineer's 'helical engine' may violate the laws of physics
Would there be issues with decelerating?
karlh··on Work of renowned UK psychologist Hans Eysenck ruled ‘unsafe’
It is the quality of the research methods used to support his ideas that are coming under fire. The fact that somebody published a study (or studies), even in well-respected journals, does not compensate for poor design. Likewise, poor design and unsupported conclusions in some studies does not automatically negate every other study a researcher has conducted. Designing, carrying out, and interpreting science is not something that can be done in headlines.
karlh··on The end of uBlock origin for Google Chrome?
Never stopped using Firefox. Chrome came from Google, the conflicts of interest were obvious.
karlh··on Amazon stops charitable donations via Amazon Smile if you turn off notifications
Better to donate directly to causes you support or through places like Kiva.org (yeah, I know they have their issues too, but still better than Amazon).
