Submission + - Thanks to robots, Ukraine is now talking about winning, not just surviving (defenseone.com)

fjo3 writes: A small but growing number of European officials and analysts are saying what four years ago was unthinkable: Ukraine isn’t just surviving its grueling war with Russia, it is in some ways thriving and may even be on a path to victory.

This isn’t yet captured in headlines—for example, about last weekend’s barrage of Russian drones and missiles around Ukraine—but in the details, like how some 90 percent were intercepted.

Several long-term trends have shifted in Ukraine’s favor, and the core reason is its fierce focus on AI and robotics.

Submission + - As data centers flock to Texas, ERCOT tries to decide which are feasible (houstonpublicmedia.org)

Tony Isaac writes: The Electric Reliability Council of Texas (ERCOT) is scheduled to vote on a new evaluation process called "Batch Zero" to manage an unprecedented influx of data centers and large energy consumers requesting connection to the state's power grid. With proposed projects currently seeking a combined 438 gigawatts of power—more than five times the electricity used during Texas's record-breaking demand—the grid operator aims to establish stricter criteria to weed out speculative or unfeasible facilities. Under the proposed system, companies will need to demonstrate readiness through land ownership, financing, and component orders, as well as make financial commitments, to ensure the grid can reliably plan for and serve legitimate economic development without overwhelming the system.

I'm sure you're familiar with the countdown protocol, all the pre-flight checks, etc. These power up a range of subsystems, motors, etc, so that everything can be verified prior to ignition itself. The complete sequence takes a very long time. Under normal flight conditions, you can't check for absolutely everything (instrumentation is mass, and mass is the enemy) but there's still a lot. However, during an engine test, you can pack a lot more sensors in.

This is where you'd want to be spotting loose connections, pumps that aren't quite even, pressures that aren't as steady as they should be, vibrations that shouldn't be there or do not match expectations, turbulent flows, and so on.

At ignition, it takes between 3-6 seconds to go from stopped to 90% thrust. For humans, that's near-instant. For a computer sensor that's operating a million samples per second, that's 3-6 million readings. A computer performing a billion calculations per second shouldn't have much difficulty in comparing 3 million readings against model predictions and determining if both the values themselves and the rate of change at each point such a sensor exists are all good. Emergency shutdowns during those first 3 seconds are perfectly viable.

Vibrations are the ones that are likely the most interesting, because those are likely to change before something breaks, not sure how fast you can make infrared sensors, but that's also an area where things are likely to alter before point of failure.

The evolutionary pattern was created because food was unreliable and energy demands were unpredictable - but high, due to the large brain. (Possibly larger than it is today, but there seems to be conflicting data there.)

Now, rationing extreme energy foods is certainly one option, but it's not a particularly satisfactory one as the energy demands vary by profession and by time within a profession. You simply can't predict what people will need and there's no way to standardise this.

There is a second option. Intense focus is impossible for beyond about 45-90 minutes at a stretch, or for more than 3-5 hours in a day. Meetings degrade intelligence, according to psychological research, so you want to minimise those. After about 7 hours, work will mostly have negative value. If you increase the amount of high physical activity for at least an hour a day (and potentially longer if the amount of soft work is minimal in the job) then you will improve physical fitness and general health, without having to substantially alter diet. However, that still only gets you so far, because a poor diet still impacts physical and mental health, and can lead to brain decline. (It's a big factor in poor brain health in children in schools.)

A third option, then, is to actually improve meal quality in schools and for workplaces to work with the food industry to provide cheaper/easier access to high quality foods that actually taste good, not merely sensible energy foods. This would seem to be target solution, with in-work exercise to supplement it.

Whilst that is perfectly true, it is questionable as to whether it is useful or necessary. If a rocket is being tested, then logically it should be heavily instrumented. If it's heavily instrumented, and the instruments are themselves competently designed, there is no obvious reason why the engine can't be auto-cut when problems start to arise. And they will have arisen long long before the explosion.

The values may have independently been "within permitted range", but if the pattern of those values doesn't make sense, then something has gone wrong. There may well also have been subsystems that were insufficiently instrumented.

"They're the experts" is often an irrelevancy - we lost TWO shuttles and crews to political decisions, when the experts on the ground were ignored. DeHavilland lost endless Comets to basically the same blunder, when political decisions by management over the reality of metal fatigue overrode analysis by actual experts. Improper monitoring and inadequate computer controls will be from a burden of costs and time (both political constraints, not engineering constraints). As, indeed, will improperly manufactured parts, improper software (anyone rememebr Arianne IV's mishap due to buggy software?), improperly-defined constraints, and inadequate quality controls.

The experts are usually either well aware of mistakes or afforded no means of detecting them.

I see no reason not to think this was anything other than a management blunder.

Submission + - RIP: Marcia Lucas, Oscar-Winning Star Wars Editor, Dies at 80 (thewrap.com)

schwit1 writes:

Marcia served as part of a three-person crew editing both "Star Wars" and "Return of the Jedi." On the first film, she worked alongside Paul Hirsch and Richard Chew and was personally responsible for editing the Battle of Yavin — otherwise known as the iconic "trench run" sequence near the end of the film. For "Return of the Jedi," Marcia shared credit with Sean Barton and Duwayne Dunham, with George citing her as responsible for the "dying and crying" scenes to Time.

That "dying and crying" is pretty significant in "Return of the Jedi," a film that hinges its third act not on a massive battle (though there's plenty of space action, too), but on a father sacrificing himself because his son believes he's not beyond redemption. In general, Marcia has been credited as, in some respects, the heart of the "Star Wars" franchise, working tirelessly to ensure that moments like Han Solo's grand return to the Rebellion at the end of the original film landed with emotional impact for the audience.

Flashback: Marcia Lucas, the 'secret weapon' behind the original Star Wars . And Raiders of the Lost Ark: "'[Marcia] was instrumental in changing the ending of Raiders, in which Indiana delivers the ark to Washington. Marion is nowhere to be seen, presumably stranded on an island with a submarine and a lot of melted Nazis. Marcia watched the rough cut in silence and then levelled the boom. She said there was no emotional resolution to the ending, because the girl disappears. 'Everyone was feeling really good until she said that,' Dunham recalls. 'It was one of those, 'Oh no we lost sight of that.' 'Spielberg reshot the scene in downtown San Francisco, having Marion wait for Indiana on the steps on the government building. Marcia, once again, had come to the rescue.'"

This raises a very important question. If the CIA are taking shortcuts and making assumptions about anything, we should not be making assumptions ourselves that the CIA aren't doing the same elsewhere. I am, however, still waiting for biolabs and WMDs to turn up in Iraq - something for which they appear to have ALSO taken one person's unsupported word for. They also ratted out their own officers in retaliation for questioning the existence of "yellowcake" (that turned out not to exist).

I'd be wary of claiming there was a pattern, but... They do seem awfully incompetent.

In unemployment figures don't show actual unemployment, but deliberately excludes groups for the purpose of keeping the figure low (and the UK was very explicit that this was the purpose when Thatcher's government sliced several million off the official figures, less sure if the US was as honest) then it's hard to call it anything else.

Smokers are deprioritised on lung transplant lists. Foreigners have to pay. So we've already got differential service. We just say that sportsfolk who knowingly and deliberately inflict damage on themselves in such contests get lower priority on medical procedure lists as well.

Not removed - they've paid national insurance - but all procedures are on a prioritised queue already, just given them a low priority. (No, not in the UNIX sense.)

They'll get seen to, when service permits. Of course, there'd be more service if the rich paid more taxes, but that's between the sports stars and the rich. They can take care of that dispute between themselves.
