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.

The issue is how the constitution lays out the choosing of a president. Pence had to certify the results, if he had refused to do so for long enough, then that session of Congress may have ended without choosing a president.

At that point, the Constitution prescribes there is a contingent election in the House, where every state delegation to Congress gets 1 vote. There are more red states than blue states -> Trump wins.

Well, sort of. HDCP exists, and does make it harder to capture an AV stream.

For interactive content, the current push online components hosted on external servers adds a lot of complexity. While a lot of that stuff can be patched around by a very dedicated community, not every piece of content gets enough community appeal to attract the wizards to do such a thing.

And while anyone can digivolve into a wizard given enough commitment and effort, the onramp is not easy these days. Wayyy back when cracking a game meant opening the file and finding the line for 'if cd_key == 'whru686', it was much easier to get casually involved. Nowadays, DRM has gotten so much more sophisticated that a tech background is essentially required to start.

Yes, you. And me. And probably most of the people reading this, who live in the US or another Western country

Not quite. 1% of global population is ~80 million people. There are about a billion people in the highly developed nations (US, Canada, Western Europe, Japan, South Korea, and some minor others). So the top 8% of the golden billion, if we assume all in the US, the top ~25% of the country.

Intentionally did not talk about Vance, I was merely responding to the idea that using past prices adjusted for inflation compared to current prices isn't that straightforward.

Thanks for the lecture, appreciate the tone.

I see the point you are trying to make, but inflation doesn't quite when that way.

Comparing the prices of the same commodities at two different points in time is literally how inflation is calculated, the increase from $1.50 to $4 is real.

Now, what the inflation-adjusted dollars are telling you is that if eggs had only increased in price commensurate with general inflation, they would have gone from $1.50 to $2. The extra $2 increase is above what a consumer would expect given the general increase in the prices of everything else. If someone (magically) had a salary that increases with inflation, they would find eggs today to be a larger fraction of their spending if they kept the same level of consumption.

Eggs are more expensive both in absolute and relative to other products. The reasons for this are complex, but due in no small part to people continuing to buy large quantities of eggs even when they were heinously expensive in the early days of the pandemic. The market absorbed that information and came to the conclusion that eggs were previously undervalued.

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

Just jumping in to say that red soils are not very fertile. They are nutrient-poor in the necessary macro-nutrients (nitrogen, potassium, and phosphorus) and have a very poor ability to retain water. They are very rocky - little organic matter content - which limits both water retention and cationic exchange capacity (affecting N+ and K+ bioavailability), and tend to be acidic.

Cultivation is possible, but it requires large amounts of fertilizers and soil conditioning agents (liming to raise pH and add calcium, addition of organic matter). In effect, recreating an artificial soil that is closer in nutrient availability to the black soils present in the world's most fertile regions (which today are also heavily fertilized).

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.

Bro delete this I just shi myself omw to work

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.
