It depends on the type of fusion.

The easiest fusion reaction is deuterium/tritium - two isotopes of hydrogen. The vast majority of the energy of that reaction is released as neutrons, which are very difficult to contain and will irradiate the reactor's containment vessel. The walls of the reactor will degrade, and will eventually need to be replaced and the originals treated as radioactive waste.

Lithium/deuterium fusion releases most of its energy in the form of alpha particles - making it much more practical to harness the energy for electrical generation - and releases something like 80% fewer high energy neutrons -- much less radioactive waste. As a trade-off, the conditions required to sustain the reaction are even more extreme and difficult to maintain.

There are many many possible fusion reactions and multiple containment methods - some produce significant radioactive waste and some do not. In terms of energy output, the energy released per reaction event is much higher than in fission, but it is much harder to concentrate reaction events, so overall energy output is much lower until some significant advancement is made on the engineering challenges that have plagued fusion for 70+ years.

Pretty sure he is talking about Burn After Reading, the green text image is from that movie.

Don't see mention of fixes for the resume-from-sleep bugs that have been around since at least 6 :'(

No, not even close.

I've used Unix systems for years at work, and have dual-booted windows with various flavors of Linux at home for just as long. When I just need something to work, particularly something new or after a stressful day at work, I just use windows.

Why? Because it will just work. Maybe it won't work precisely how I want it to, maybe it will send all my data to Bill's push notifications, but it will run. In the rare case it doesn't, a quick google will fix it.

Compare that to Linux, where most things will work most of the time. And when they don't, you get to hunt through GitHub issues off-the-clock like a peasant, wading through comments from people with entirely different configurations and 'dunno it works for me'.

Linux is for tinkerers, and for people who want a Unix shell and can't afford a Mac, it has a long way to go to be more than that.

An inherent flaw in transformer architecture (what all LLMs use under the hood) is the quadratic memory cost to context. The model needs 4 times as much memory to remember its last 1000 output tokens as it needed to remember the last 500. When coding anything complex, the amount of code one has to consider quickly grows beyond these limits. At least, if you want it to work.

This is a fundamental flaw with transformer - based LLMs, an inherent limit on the complexity of task they can 'understand'. It isn't feasible to just keep throwing memory at the problem, a fundamental change in the underlying model structure is required. This is a subject of intense research, but nothing has emerged yet.

Transformers themselves were old hat and well studied long before these models broke into the mainstream with DallE and ChatGPT.

There is always a tension between security, privacy, and convenience. With how the Internet works, there isn't really a way - with current technology - of reliably catching content like that without violating everyone's privacy.

Of course, there is also a lack of trust here (and there should be given the leaks about mass surveillance) that the 'stop child porn powers' would only be used for that and not simply used for whatever the powers that be wish to do with them.

The world bank isn't involved so much in printing money - that's central banks like the US Federal Reserve or European Central Bank.

They do love to force developing nations to adopt US-style capitalism by withholding loans for needed development projects. They also focus far too much on increasing GDP at all costs and do not give really any weight to increasing living standards or reducing inequality. Basically, think loans to institute Reaganomics and you won't be too far off.

The loans pay for large capital projects (power plants, large-scale irrigation, etc) that are built by the state and then mandated to he handed over to private entities that then charge rents and extract wealth. Not every loan and program is bad, but there's plenty to give pause when they are involved in a project.

Cats convert CO to CO2, and NOx to N2 (mostly irrelevant for this conversation). In closed space, the exhaust is still deadly, but you are correct in that CO would cause quicker death than CO2 displacing the oxygen.

Relatively low concentrations of CO will cause severe drops in red blood cell's ability to transport oxygen, then follows unconsciousness and death. CO2 in contrast would require higher concentrations to be effective, as it would only reduce the efficiency of gas transfer in the lungs and lead to slow and painful decreasing blood pH - and a strong panic reflex and the 'I can't breathe' feeling - until eventual unconsciousness and death.
