You can disrupt GPS to slow down establishing a connection. You can slow down the link with lots of local ground-generated RF noise. You can fly drones or planes that discover terminals and jam them. There's no such thing as an unjamable radio. However, with 10-20 starlink satellites "visible" in the sky at any given time and the average time overhead being less than 10 minutes, a terminal should be able to find a clear line of sight intermittently.

A skilled jamming operation would use drones to discover terminal locations by listening for transmissions and just physically attack them. At that point it becomes a numbers game and an arms race.

Bottom line: insurgency has low bandwidth requirements. Iran can probably disable 80 to 90% of Starlink traffic but the last 10% is more than enough to coordinate against the regime.

Maybe the US should colonize it.

No. Not really. But seriously, the people running that place are deeply evil. Arresting children for *reading* social media posts. Arresting people for quietly reading the Bible in public. Arresting people for defending themselves from gang violence. Forced digital ID? Draconian capital controls. Security cameras on every corner. Attempting to repeal Brexit against the will of the people.

On the other hand, they haven't started killing populist politicians en mass like Germany. Yet.

labrador's law: Only agitated dogs bother barking

The average post online gets something like 1000x more views than comments or replies. A post generally has to pass the viewer's threshold of emotional response to elicit the effort of a reply. Therefore, the responder either has a personal connection with the author or subject or feels strongly about it, and as such, the response is much more likely to be polarized, given the rarity of passionate moderation. This is a key contributing factor to online polarization: the majority does not feel as strongly about most issues as the people writing articles or posts about the issues. However, over time, saturation of the online media landscape with polarized posts and replies gives the illusion of higher polarization, which probably leads people to feel and believe that the issues themselves are polarizing and that most people ARE polarized on the issues.

Because we generally take sides in politics based on social acceptance rather than individual evaluation of the issues, the discussion becomes even less rational. If my social group is almost completely party-aligned, I will be much more likely to simply accept and promote the 11th-ranked plank of my party's platform than to depart from it, risking social isolation unless I deeply care about that particular issue.

This is why the most important issues are never the leading planks of a party's platform, but the most devisive issues ARE the leading ones, even if they are sometimes the least important, because that's how you gather support. Consider issues like abortion, racism and non-traditional sexuality. None of these issues affect more than 25% of people directly, yet they are hot-topic issues that drive emotional support of political parties.

Everyone who makes actual economic decisions based on this kind of data have long-ago abandoned confidence in government reporting. It's politicized and it's been systematically sweetened to preserve the illusion of low inflation and higher employment for decades. The fact that people don't want to answer questions may have as much to do with distrust of government as anything else. Why waste your time?

Consider the counterfactual. If it was the Swedish government from the 1990s asking you to answer questions, you'd probably take it seriously because it would credibly inform responsive policy.

BLS stats are mostly just headline generators for the propaganda machine.

Comment I have a question (Score 0) 186

Has anyone here done serious investigation into the reliability of the models and research indicating that human activity is causing climate change? I keep hearing that anyone who publishes research contrary to the dominant narrative becomes effectively unemployable. Is there evidence that the research is unbiased?

1. MEMS clocks with microsecond-per-day accuracy are commercially available and they're getting better.
2. 1 ns drift = 30 cm position accuracy.
3. You still need signals from known positions to triangulate your location.

So while jamming GPS is trivial, the alternative is using other sat networks or building terrestrial radio beacons. Variations on the same problem. Just having accurate, portable clocks does not help.

This article boils down to: UK is working on portable atomic clocks, just like everyone else.
