JUDGE: The jury has sent a question and the answer is no, the death penalty is not "available for both sides" please return to the jury room and limit your consideration to civil damages.

JUDGE: No, a “light maiming” is also not acceptable, nor is “getting medieval on their asses.” Please constrain yourself to statutes approved by this court.

JUDGE: A further follow-up question from the jury, and no we cannot 'dunk them in a lake and let God decide, like they used to do with witches'. That has not been considered a valid means of determining guilt for several centuries at least.

JUDGE: The jury has sent another question and the answer, again, is no. "Excommunicado" is not real - that's only a thing in the John Wick universe. Civil penalties DO NOT encompass revoking all protections under the law for Mr Altman and Mr Musk.

JUDGE: Court reporter, please note that the jury's latest request, quote, can we let them hang by their thumbs for a few hours, end quote, is also denied.

Nuclear reactors use most surface water, not ground water.

Datacentres are no pickier. You can even cool a datacentre with saltwater, you just need a heat exchanger.

Also, closed loop does not evaporate. The loop is not closed if stuff escapes from it.

You're arguing with the actual terminology used in the nuclear industry. "Closed loop" or "closed cycle" designs have the water pumped in a cycle through cooling towers. The towers lose water to evaporation, taking heat with them, but the rest of the water is returned to be reheated again. "Open loop" or "open cycle" designs have no cooling towers. The water is heated and just discharged hot. They consume much more water (over an order of magnitude more), but most of that is returned. Closed loop are more common, but you see open loop in some older designs, and in seawater-cooled reactors.

I've printed many hundreds of kg on my P1S, thanks.

I do not consider having to write data out to a card and transport it back and forth between the printer and the computer to be the pinnacle of convenience. That's something that would be considered embarrassingly inconvenient for a 1980s printer, let alone a modern net-connected device. And it's designed to be inconvenient for non-cloud prints for a reason.

I have no complaint with the idea that most students simply won't be able to achieve an A-grade if the material is both challenging and taught to proper standards, but I have a major problem with the notion that teachers are required to deny students that have mastered well above 90% of the material an A-grade because other students managed to yet outperform them. I hate the idea of grading on a curve. One should be judged against the mastery of the material, not comparatively against other students during that particular semester.

That said, I have also had college classes where I really should have failed the class but because of the curve, I got an A because I had the highest scores. While some of that reflects upon me, a good chunk of that reflects upon the instructor, the department and its head, and the curricula for that particular course. If students are to be held to high standards then instructors should likewise be held to high standards, and so should their institutions. If they cannot produce results then that should reflect both upon them and upon the revenue they receive in tuition.

Also, anything sounds big when you put it in gallons. Doesn't sound so big when you mention that's 92 acre feet, the amount used by less than 20 acres / 8 hectares of alfalfa per year. Or when you mention that a typical *closed loop* 1GW nuclear reactor uses 6-20 billion gallons of cooling water per year (once-through uses 200-500 billion gallons, though most of that is returned, whereas closed loop evaporates it)

I don't think it has anything to do with that. As soon as I saw the headline, my mind went "cohort study". And sure enough, yeah, it's a cohort study. Remember that big thing about how wine improves your health, and then it turned out to just be that people who drink wine tend to be wealthier and thus have better health outcomes? And also, the "sick quitter" effect, where people who are in worse health would tend to stop drinking, so you ended up with extra sick people in the non-wine group? Same sort of thing. This study says they're controlling for a wide range of factors, but I'd put money on it just being the same sort of spurious correlations.

They've made a nice easy-to-use ecosystem. For $400 you can get a P1S that supports adding an AMS, auto bed leveling, enclosed-chamber printing, high precision, high print speeds, and 300/100C nozzle/plate temps, and has an easy cloud print service and a robust ecosystem of models you can just download and print with no extra config straight from the app.

But yeah, their behavior is increasingly entering bad-actor territory. I wonder how long it'll be before they lock entry-level printers into their branded filament?

It isn't colonial, it is industrial. The current format of school is that of preparing for a factory workforce. We are post industrial, knowledge/AI/Whatever it will be called workforce.

Educators need to come to grip with getting EVERY child their MAX educational value we can. This means breaking the rows and columns of desks in a classroom, and getting kids their most valuable education they can get. This means some will do much better than others. Talent has gradations. Not everyone can be a Astro Physics expert.

I spent 20 years working in K-12 in a suport role. The issues vary greatly across population densities and social and economic status. The large district I worked for (~55,000 students) featured everything from schools where every kid must be prepared to go to college, to trying to arrest the pregnancy and dropout rates.

The problem is when education is treated as a monolithic bloc. Issues vary incredibly widely from school to school, from neighborhood to neighborhood. An additional problem is the attack stemming from the anti-tax crowd on public education, eroding budgets and thus paychecks, generating disrespect for teachers, and causing many to leave the profession for something that pays better. That leads to erosion of the system and it starting to break down.

Comment Phablet? Rugged? Oh pls. Oh pls. (Score 1) 41

These are awesome and I would absolutely embrace the upgradeability and open standards fully if they had the devices I use: a rugged laptop (rain, snow, drop, etc proof, covered ports, washable like my Getacs) with upgradable, fully Linux compatible hardware would be awesome. My trackpad and touch screen are both generic mice according to Linux.

Then, pls, make a phablet with optional LTE/baseband (or none, not a phone at all). Short range radios, but zero base band, otherwise a rugged, reliable, durable, upgradable phone-like form factor, super extra bonus points for interchangeable camera modules. Double extra bonus points for easily removed/swapped battery. Add a LoRa radio instead of LTE, why not?

There have been a few projects to make a good Linux phone and while the PinePhone is impressive engineering, it falls short of being a usable replacement for a flagship phone. There's a solid market for brick/tank phones and they have plenty of room to provide usable, all day battery capacity for a Linux device but the current collection from vendors like Blackview, as nice as they are with very useful features like thermal imagers or NIR illumination/sensors and excellent durability are all Android Certified and the Droidocalypse is going to effectively brick them all in September.

Comment Re:20+ years reading Slashdot (Score 3, Insightful) 75

Any aggregation of radioactive elements is inherently dangerous, always, no matter what safeguards, simply as a material that is hazardous to health. Most radioactive hazards associated with fissile materials represent health risks with atypically, even for poisonous elements, pernicious qualities. Not many people would be sanguine with health-impacting quantities of fissile materials in their environment, unlike say, lead or arsenic, both quite awful but a whole different scale of awful.

Any intentional aggregation of fissile material is intrinsically a risk to human health and safety. Nuclear advocates (many of whom would qualify as frothing fanbois) dismiss such concerns claiming they know of a "safe" reactor design, some of which are quite clever and are, indeed, intrinsically quite safe when operated correctly. Such fanbois will sometimes make the entirely valid point that the rate of death from even older reactor designs is way below the mortality rate induced by burning coal (true) and that nuclear power is much less carbon intensive than fossil fuels (also true).

There are compelling arguments about a diversity of sources, above the reliability of fissile power, about the longevity of investments, and about immunity to a range of possible weather (storms, extended rain) or geopolitical constraints (international fuel shipments), all of which (and more) have merit and should be considered carefully.

I consider four counter arguments that should be considered when contemplating the relative merit of fissile power generation over other methods:

1) Current advanced nuclear power plants have a projected LCOE of $0.11/kWh (DOE) standard new at $0.118-$0.192/kWh (lazard) while solar currently runs $0.05-$0.06/kWh (lazard) and $0.086 (NREL) for battery-backed 24/7 solar, declining to $0.047/kWh by 2050 (NREL). The economic justification for nuclear power is weak in all but a few geographic locations occupied by humans.

2) Uranium is a finite resource, the cost of which is rising and currently $86.8/kg (tradingeconomics). The total proven proven reserves are sufficient for about 2 years of total human consumption in standard light water fission reactors. Breeders and advanced systems have significantly different total reserve values, but such systems come with significant risks, either in proliferation (breeders) or technological (advanced reactor designs). While it is an entertaining speculative argument to discuss technologies that might extend fuel supplies, solar panels and storage (PSH or grid-scale battery) are well proven and widely available today.

3) National security policy: defense against external antagonist: any centralized civilian facility is a target and nuclear reactors, even intrinsically safe ones, are a particularly tempting target. While containment structures are designed to be robust against, for example, the impact of a large passenger aircraft, they are not robust against "bunker buster" style munitions. Consider the consequences of a relatively trivial drone impact with the Chernobyl sarcophagus. As these sorts of attacks are democratized by the proliferation of low cost, long range, difficult to attribute munitions they will inevitably become more common and the only practical mitigation is decentralization. While nanoreactors such as the Zeus (1-20 MW) might make targeting more difficult, they're still vastly more expensive than a few more drones making them juicy asymmetric targets for any NSAG and proliferate the next concern:

4) National security police: defense against extremist state takeover or occupation: "safe" nuclear reactors assume operation remains in the hands of moderately responsible, reasonable people, an assumption not supported by recent history. There is no fission design that does not rely on a concentration of fissile material, intrinsically radioactive. There is no such concentration that cannot be widely dispersed with a properly engineered application of conventional high explosives. Every nuclear reactor, anywhere in the world, is a pre-emplaced nuclear munition. To quote the (poor) AI transcription of Serhii Plokhy from the Economist's Intelligence podcast https://www.economist.com/podcasts/2026/04/24/an-explosion-still-echoing-chernobyl-at-40 "The taboo on the occupation and military attacks on nuclear sites that existed before 2022 had been broken. It is gone. Now, the war in Ukraine is the war of drones more and more. And the non-nuclear country. Can very easily go nuclear by attacking somebody's nuclear facilities like nuclear power plants." Chernobyl is occupied, Zaporizhzhia is occupied, the Ukrainians got close to taking Kursk; if an occupying force is forced out, might they be tempted to salt the earth they're forced to leave with fissile debris? Might one of the many political parties animated by an Armageddonist eschatology consider a nuclear reactor an inexpensive and readily available doomsday munition, a sort of clarion call to whatever deity they are waiting for? Even if they're wrong about the level of doom a conventional detonation of a fissile core might achieve, the consequences would be far more lasting and terrifying than a fuel depot or even grid-scale lithium battery fire.
