He has been working with Microsoft. There is a history of poor communication, lackluster responses, and a decision not to pay out a bug bounty.

Microsoft stopped responding to him privately, so he forced their hand publicly.

Sometimes community members can be ...over enthusiastic... and hard to deal with. They think that whatever they have found should be your top priority, and it just is not. It is a balancing act to keep them on your side. Somebody failed at that with him.

it's spin. "Google Pledge To Yank Search If Schools Block AI" is a horribly biased spin on the actual situation.

The actual situation is that the school districts wants to block all student access to Google AI. Google search is now AI based. If you block Google AI, you have blocked Google search. If you leave student access to Google search, they can use the AI through the search interface.

Google could certainly maintain the non-AI based search function in parallel, but they don't want to. So we have to pick a different search engine to use if we don't want to use their AI for searches.

In the future, all search engines may be AI based, but for now we can just choose not to use Google search..

Though realistically, because 240Pu (from waste) is worse in a fission bomb than 239Pu - generally no more than ~20kT, and challenging to get more than a few kT - still enough to take out a city centre but not a metro area - you'll generally want a fusion weapon, which means deuterium and tritium supplies. And Ukraine doesn't run CANDUs, so you're not going to get tritium from the coolant. They'd need lithium targets / lithium in the coolant to breed tritium. Separation of tritium and deuterium are a mix of chemical, electrochemical, and/or physical separation, but are much easier than uranium isotopic separation (deuterium is double the mass of protium, and tritum triple the mass, so the chemical / electrochemical behavior is actually notably different in a lot of situations, unlike uranium).

For a fusion bomb they'd also want a depleted uranium tamper, but Ukraine probably has ample access to that, whether from weapons, armour, old Soviet stocks, etc. Even spent nuclear fuel is mostly 238U, if they don't mind the tamper being highly radioactive.

My personal best guess would be that Ukraine's unstated policy is to have "sprint capacity", like Japan and South Korea do. That is, to not make weapons or anything that would get them flagged as having a weapons programme, but to have everything needed that, if the word "Go" was given, that they could nuclearize very quickly.

Unlike your typical rogue state that seeks to get nuclear weapons, Ukraine has no need for mass centrifuge facilities or anything like that. They already have plutonium en masse, as they're a major nuclear power generation state with extensive waste supplies. Plutonium extraction via PUREX is merely metallurgy (it's not a simple metal to work with, but it doesn't require isotopic enrichment). You need nitric acid (bog standard, nobody will blink an eye), a reducing agent like ferrous sulfamate (not much of a red flag, it has tons of uses), and an organic solvent like tributyl phosphate (a little bit of a red flag, but it has other uses, and there are alternatives), and a bit of gallium (~1%) for alloying - not a problem. Ukraine could very readily have all of this on-hand, an underground lab ready to go, and a rolodex of people to staff it if the order is given. They'd need high explosives like PBXs or TATB, but nobody would blink an eye at Ukraine buying them. High speed switches for the detonators used to be a big red flag item, but today they increasingly overlap with power electronics for motors and power grids. You need neutron initiators, but there's a number of options for that. And running bomb physics simulations and doing small component tests is something they could easily have under the radar - if they don't outright have old Soviet design plans dusted off and ready to go.

The biggest red flag would be Ukraine inexplicably removing nuclear waste (for processing) and/or trying to defeat IAEA monitoring, so that would likely be not done unless nuclear tensions looked severe. Because if it looks like you're sprinting to a nuclear weapon, it increases the odds of a preemptive nuclear strike against you.

(For a full-scale exchange...)

Also, for no particular reason, a map of Russia's population distribution, alongside a reminder of Russia's nuclear missile failure rate, particularly booster failures. And that nuclear warheads have been commonly lost disturbingly often even during peacetime, with at least seven weapons from four incidents lost in flight landing in a way that left them fully intact and easily reparable, just from the US alone. And that Ukraine is rich in nuclear engineers, including still some retirees who worked in the Soviet nuclear weapons programme.

There's also this myth that "if you just use a nuclear weapon, you automatically win the war". Nuclear weapons are immensely effective terror weapons, but their effectiveness on the front is a lot weaker than most people think. People on frontlines tend to be in trenches, bunkers, basements, armoured vehicles, etc, and can be surprisingly close to a tactical nuclear blast while still surviving. They're effective against hard points but struggle against a broad, diffuse front (aka, today's front, which is a sparsely populated, deep, amorphous zone, thanks to drones). Amortizing Russia's estimated budget for tactical nuclear weapons comes up with ~$15-25M per weapon (not counting the delivery system), so they're hardly a dime a dozen either.

IF, via terror bombing or threats of terror bombing, you can convince your enemy to surrender, then congratulations, you have won (enjoy your nuclear waste heap and restive population who wants nothing more than to kill you). If they do not, however, their only goal remaining will be to focus 100% on using their extensive nuclear waste supplies rich in plutonium, their extensive long-range strike weapon supplies, and their extensive metallurgical experience, to render your major cities to ash in the same way that you did theirs.

(I also just assume herein that Ukraine doesn't actually have a secret nuclear weapons programme already, which is certainly an assumption).

To be clear: you can still totally argue about qualia, sentience, things of that nature. What is not up for debate is that they work through unimaginably-complex chains of logical reasoning on superpositions of conceptual states and engage in forward-planning and metacognition. These are just demonstrable facts.

No, it's called "Evidencing The Fact That It's A Widespread Shorthand" (in specific, among Wikipedians, where it's in official terminology as well), a widespread usage that was falsely claimed to not exist.

Okay Felicia.

TL/DR: "copyvio" is the Wikipedia-standard shorthand for copyright violation, used both in direct speech and in official templates. If a person says "copyvio", they've probably spent a lot of time hanging out at Wikipedia, where copyright violation is a frequent topic of discussion.
