Comment Briefing is also a sales pitch (Score 1) 92

I saw a bit of the briefing and Duffy talked a bunch about Congress needing to appropriate them more money so "Trump can build" a more modern network, before he leaves office, 'cause the current system is old and this is a "National Security issue" (sound familiar), etc. He's not wrong about some of that, but ... [puts on tin-foil hat] ... maybe this was just a manufactured "crisis" to get more funding, or someone actually hacked into the system ... [takes off tin-foil hat] Extreme conspiracy thinking, I know, but I wouldn't put things like that past this administration, one known to lie, obfuscate or just be incompetent. [takes off backup tin-foil hat] :-)

The straightforward solution is for the UPS manufacturers to jitter the test time and it becomes a total non-issue.

From TFA:

Fortunately, the solution may be relatively straightforward, at least for big batteries and backup systems. Rather than having thousands of devices perform the same task at the same moment, manufacturers could introduce small variations into their software schedules, preventing the minutely pile-up.

Indeed, they have already contacted the manufacturer of one of the systems they identified, and the company issued a software update that relaxed the strict periodicity of its system checks.

Submission + - Power Grids on 5 Continents Pulse Every 60s. Scientists Think They Know Why (sciencealert.com)

fahrbot-bot writes: ScienceAlert is reporting that researchers may have finally determined why, for many years, power grids around the world have been pulsing every 60 seconds: uninterruptible power supplies running routine battery checks.

Every minute, some uninterruptible power supplies perform routine battery checks, creating small but measurable surges in electricity demand. And it's like clockwork.

"Even benign control routines can become systemically relevant when many devices act coherently," writes a team led by physicist Dirk Witthaut of the University of Cologne, Germany, in a paper published in Nature Energy.

"Unintended synchronization can generate recurrent and potentially amplified oscillatory behavior in large-scale cyber-physical energy systems."

To figure it out, Witthaut and his colleagues analyzed high-resolution electricity measurements from buildings at the Forschungszentrum Jülich research campus in Germany. They found the 60-second pattern appeared in four buildings, all of which contained uninterruptible power supplies. None of the buildings they measured without these systems showed the same pattern.

Following the electrical signals more closely, the researchers detected tiny bursts of current from the batteries at precisely one-minute intervals. They were able to trace the resulting fluctuations through one building's electrical system, all the way to the connection with the public high-voltage grid.

The manufacturer subsequently confirmed the culprit's identity – routine battery self-tests, conducted automatically by the systems' management software.

But why would equipment in different buildings, let alone different countries, be doing this at the same time? The answer appears to lie in the clocks. Digital devices can synchronize their internal clocks using external time signals, meaning that independently operating systems can end up performing their scheduled tasks together.

Individually, these small checks are insignificant. But when enough devices act in synchrony, their combined electricity demand can produce a measurable effect across an entire power grid.

Made me think if this exchange from South Park, "Make Love, Not Warcraft" (S10E08) between Randy, the president of Blizzard Entertainment and their Board members:

President (Blizzard Entertainment): We're too late. Without the sword the players will fail.

Board Member 1: I-if we could get to a computer, we could sign on to the World of Warcraft and give the boys the sword online.

President: I don't have a World of Warcraft account. Do you?

"reality has a well-known liberal bias"
As we both know, reality has no bias; but Colbert's comment is so delightfully self-affirming that narcissist progressives can't stop repeating it as fact.

Personally, I think any society needs both liberals and conservatives to be healthy. Lately, progressives seem to delight in actually killing conservatives. (shrug)

Liberals cheerfully explore the world, and while many fall off cliffs, get eaten by bears, and eat berries that kill them, the ones that survive make progress possible. Without them we wouldn't have found wonderful new places better than where we were, animals to domesticate, and delicious berries that are good for us. Confident, naive liberals die in droves but pull civilization forward.

OTOH, conservatives are insurance for survival. They DON'T explore where stronger, dangerous hostile tribes may lurk to be led back to our village to enslave/kill/eat us. They don't eat those lovely red berries because the blue berries our ancestors have eaten have kept us healthy and well for centuries and are good enough, thank you. They do not accept strangers because if someone was a decent good person, why would he have been driven out of HIS village and come here?

Which is more important, survival of our tribe, or advancement for our tribe?
Trick question: both. The tension between sides is fine, rational, and normal; both should be encouraged. In a healthy society, our educational system would put out both.

What's odious to me is certainty. (To be clear, I find the same sort of certainty among Evangelicals and it is equally if not more repellent. And I consider myself a person of some Faith, maybe that's why?)

I get it; as a liberal you *have* to be confident that whatever whacky bullshit you're following today MUST be right, it MUST be better, or you wouldn't chase after it like an OCD squirrel. What's ironic is that most of the values leftists insist are core humanist values - even humanism itself - was born in the hearts of deeply religious men like Luther, Erasmus, and Scottish Presbyters.

Nationalize the discussion all you like but the US government itself isn't secure if it depends on Starlink, Microsoft, Google, or Amazon, either. To assume assume that these each have a nationalist bias is one thing, to assert that it is automagically in line with the policies and goals of the US government (or the party in power, if you will) is provably absurd.

The internet has become a major strategic context (resource? arena? theater?). Any country that maintains its sovereignty MUST insist that they control their own destiny there. OTOH only China can really say that national/corporate interests align reliably; it takes a level of central planning and control that most* would say is odious to western democratic humanism. In the west, I believe it's farcical to think that a government could possibly keep up with megacorps in this realm; it just demands too much nimbleness. So we have governments which MUST depend on corporate actors to stay in the race.
It's a puzzle which is only being repeated in AI.

*honestly, I'm not even sure what passes for western democratic values any more. Free speech? Free thought? Free religion? Secret ballots? Informed electorate?
