New comment by darfo in "America Is Losing Blue Collar Jobs"

This article uses quantities when percentages provide a different perspective.

"The country is down 65k industrial jobs over the last year..."

The second graph for US Blue Collar employment shows 100K jobs lost from the 2025 peak to the end of the graph.

Jobs went from 29.05 million down to 28.93 million [visual guess on my part].

My take: less than 1% drop in industrial jobs in since 2025 peak could be simple adjustment after pandemic induced flucutations.

IP Check makes this incomplete statement about my IP:

”Good News! Your IP address shows no signs of malicious activity. Keep up the good security practices:"

Should say "that we can detect" else I might get a false sense of security.

Can the OP change the HN item title so scrollers don't think there is a problem with MRI? Isn't fMRI being questioned?

"It also produced more false positives than humans, sometimes mistaking harmless network signals for signs of a successful breach. The researchers noted that the system performs best in environments dominated by text-based inputs and outputs."

How many more? The article doesn't say.

Title should begin with "Maybe".

Julian Jaynes proposed this as a hypothesis.

"...particles from tires, brakes and dust...". So blame the EV chargers? How about doing something about the tire and brake dust? It is not like the wind can't blow that around. Maybe put filters on the wind /s.

The article cited [0] discusses ventilated filters, not all filters. It is a dodge for regulator's smoking machines.

Since I think people are going to smoke a better solution would be mandated biodegradable filters. Unfiltered cigarettes must be worse for smokers than filtered cigarettes. Unless the filter material itself is dangerous :)

nice works for me nicely, with less typing if it's a CPU issue. If it's memory depletion it's no help.

Got working after I figured out the argument should be the command I’m interested in. And it must be run as root if not my process because of pmap -x

One-liners are cool.

Why are tax dollars being used to catch criminals that think they are preying on other criminals? I realize in this case the DEA are pretending to be criminals.
