Comment Re:The problem is the right of way (Score 2) 102

... It is too curvy.

... The curves are on land.

However the basic problem is that raising the maximum speed is not going to make any difference when the previous trains couldn't reach their maximum speed either.

https://www.sealytutoring.com/... The curves on dedicated bullet-train tracks (not shared with slow-commuter trains and not shared with freight) must be curved to attain even moderately high speeds end-to-end on the line. In this regard, railroads are not that much different than banked curves on high-speed automotive roads that has been state-of-the-art for many decades now. Half-hearted attempts to achieve bullet trains in the USA need to quit living in the 19th-century past of the Promontory-Point-era concept of what a railroad is and is not. Indeed, the USA needs to decide whether it wants bullet trains as true high-speed rail or me-too also-ran participation-trophy kinda sorta a little bit fast trains for which we use the pathetic term "high-speed" rail instead to make ourselves feel good as a national-pride salve in a failed-engineering wound that Americans don't like to talk about. Aspire to even remotely be in the same league as the Japanese, or go home and hang it up and retire as a has-been.

Comment Did the AI chat advise the suicider on the how? (Score 2) 112

It all comes down to: did the AI chat advise the suicider on the specifics of how to enact suicide, step by step? If so, then the LLM as trained (and possibly its trainers) are culpable in this suicide, and this case should be precedent-setting. If not, then entirely a non sequitur and the family is barking up the wrong tree due to heightened emotional state just to vent their emotions.

Okay.. And how did they get the now-solid puddle back into the reactor on Monday morning?

Heaters surrounding the container below the reactor melted the salt. Pumps pumped the molten salt back into the reactor on Monday morning. Protons irradiated the molten salt to start the fission again.

Even as an energy source, nuclear power has often presented a choice between [...] versus headline-making events like 3 Mile Island and Chernobyl.

The melt-the-drainplug fail-safe molten-salt reactors (MSRs), such as liquid-fluoride thorium reactors (LFTRs, pronounced lifters), do not have that melt-down capability of the backups of the backups of the backup failing, because by less-is-more engineering design all those layers of backups are unnecessary to keep it safe in the first place during normal operation. Weinberg's team at Oak Ridge National Labs during the 1960s would intentionally cause the LFTR analogue of a Chernobyl, Fukushima, or Three-Mile-Island event every Friday at 5pm to passively shut down the MSR by melting its drainplug (so that they could go home to their families for the weekend). How to melt the drain-plug? Shut off the fan that cooled the drain plug so that it is no longer cooled (just as any disaster would). The nuclear reactors popularized worldwide post-WWII were fail-disaster high-pressure, low-temperature reactors that placed the fuel in rods and utilized water that could boil as coolant; MSRs are fail-safe low-pressure, high-temperature reactors place the fuel in molten-salt liquid and utilize that same liquid for initial heat transference in the radio-active zone of the MSR. To shut down the MSR (either intentionally during normal operations/maintenance or by passive happenstance during disaster without any human act whatsoever, the extremely hot liquid reactant is drained into a storage tank below, where it both ceases the nuclear reaction as well as solidifies as it cools (until heaters that restart the MSR melt it again as overt intentional act).

Cardano's ADA cryptocurrency software is the most-likely explanation for OP. One interesting piece of evidence is that AdaCore (the sole remaining compiler company developing an Ada compiler to the latest revisions of the ISO standard for Ada) is clearly diversifying to Rust and C++ recently.

Comment Re:no due process (Score 2) 24

For example, a bot malware could be downloading pirated copyrighted material unbeknownst to an ISP's subscriber. Due process would permit that subscriber to be found innocent. Due process would instead deflect the justice system toward the operator of the malware bot instead, perhaps as organized crime.

Comment no due process (Score 4, Interesting) 24

The main thing wrong with what Universal, Sony, Warner Bros, and major record labels sought was that it lacked due process. Only the ultimatum from the corporate gods sufficed to trigger one-sided one-size-fits-all justice. SCotUS needs to focus especially on the constitutionality or lack thereof of regarding that point.

DesScorp is obviously saying that The Guardian tries to shape the minds of a labor socio-economic class in the UK that is more pedestrian & proletarian about its blue-collar-focused needs & mental state than The Guardian's editorial board and journalists will ever understand.

Comment Yet another invention reified from science fiction (Score 1) 86

Ayn Rand's _Atlas Shrugged_ had a main character named John Galt who invents an electric motor for Twentieth-Century Motorcar Company that is powered by the Earth's rotation (instead of by batteries and instead of by hydrogen-oxygen fuel-cells and instead of by hydrocarbon fuel-cells). Perhaps soon we will have a volume-hologram clock and a volume-hologram calendar projected above each metropolitan area, which also was an element of science fiction in _Atlas Shrugged_.

Comment gossipy hallucinations (Score 1) 100

All too often AI chatbots give out gossipy hallucinations instead of distilled solidly true facts. Usually AI chatbots refuse to divulge footnotes to all of their (supposedly) quoted/paraphrased sources. Between these 2 defects, the human-being user of (or worse, another chatbot being trained from) a chatbot has no idea in the end what is true fact versus falsehood. At least in real life with an in-person human being, a receiver of information can perceive tone of voice, body language, and other clues to discern confident truthfulness versus making shit up entirely versus intentional-lie deception, but AI chatbots lack that ability to be perceived, speaking only via textual words that can be misconstrued as much as, if not more than, email that for decades has been notorious for being open to outlandish misinterpretation of implied or unintentional meaning as subtext beyond the textual words.
