Current legal doctrine is that _forcing_ payment (i.e. cash for privacy) is not allowed, that does not mean you cannot offer a subscription that disables tracking: you just have to offer a free option as well, which they do.

The only indication that openai is profitable comes from openai (whom I wouldn't trust with any statement, especially when it comes to profitability).

In fact there is evidence that inference is not profitable simply because the rate of losses doesn't seem to reduce as revenue increases: if inference had great margins, we would expect that as revenues increase, the amount of spend on training reduces as a fraction of total expenses. Since the loss-making fixed costs shrink as a fraction compared to the profitable inference, we should expect profitability to rise with total revenue.

However, all leaks of openai's numbers seem to suggest the opposite: as revenues increase so do the losses.

NTN satellites induce some quite significant challenges compared to standard 5G networks. I think most people can already imagine that delay is a considerable challenge, but that is ultimately relatively easy to deal with by adjusting the constants (like HARQ timers) in the 5G standard. A bigger issue are things like extreme doppler shifts induced by the high speed of LEO satellites (27000 km/h), which means that your UE has to continuously pre-compensate for doppler shifts. Another bit of weirdness is that cell handovers are now "reversed" compared to ground systems: In ground systems the reason you need to switch cells is usually because you moved away into a different cell. In LEO systems the "tower" and therefore cell moves. If you don't want to have constant re-negotiations with the cell, you need to have some sophisticated beamforming on the satellite to keep the cell steered onto the same ground area (i.e. the cell needs to move from the POV of the satellite to stay stationary from the ground side).

All of this is quite expensive, a lot more expensive than just having ground based hardware. From a purely economic POV these systems don't really make sense unless you have externalities like defense as a secondary argument. The catch 22 for NTN is (and arguably will always be) that it is the most worth it for regions far away from the existing network. However, since regions without cell coverage are almost surely not very affluent, they themselves cannot reasonably afford the extra expenses to justify a satellite communication system. There basically has to be governmental support from the defense or just "public good" coffers to make this reasonable. NTN will be a supplement for existing networks for the foreseeable future.

Regarding Java, SAP has long switched over to openjdk (though oracle java is supported in some cases). Specifically, they have their own custom fork of openjdk "SapMachine" precisely to be independent from oracle (FYI: if you look at openjdk upstream you will see many core contributors are employed by SAP)

In general, I would say that the actual tech companies that have to interact with oracle's stuff are generally very well equipped to drop them or have already done so. The bigger issue are legacy "consumers" of oracle (e.g. if Pepsi has their data in oracle DB), which often do not have such contingencies.

The main problem they have is that you just need a fraction of the number of people to build an electric car than what you need for a combustion car. You no longer need complex transmission, exhaust filtering, turbos, highly complex combustion engines,... all of which are marvels of engineering but no longer necessary for EVs. VW "main" (i.e. excluding sub-brands like audi) was already rather highly staffed (though part of this is due to them taking over some duties for their sub-brands), so the employee impact is higher than what you would expect, but even for a reasonably staffed car company this would imply huge layoffs and changes in the structure of the company.

The EU cannot control every avenue you might be sneaking products out for destruction. The goal is not to prevent all sort of destruction, just make it risky enough not to be worth it: Since it's illegal to do, you now have something to fear when you try to get away with your (now) crime.

ESPR regulates the entire placement of products, not only the destruction, e.g. the Digital Product Passport (DPP) which every product has to have (it's slowly being phased in over the coming decade) gives information about repairability, resource used, recyclability,... To do the exporting for destruction you would need to fake the entire paper trail of the product, committing countless numbers of document forgery.

In general the "you are not allowed to destroy unsold goods" part is arguably the small element of ESPR. ESPR also contains the right-to-repair legislation, where ESPR introduces requirements (or at the very least disclosure requirements) for - Design for durability - Availability of spare parts - Access to repair information - Software support obligations - Design for repairability / Restricting design practices intended to hinder repair

The "don't destroy working items" is just a one component of this. The more important component is the DPP which makes the product lifetime traceable.

The bigger issue is that console manufacturer revenue is highly cyclical. This is hard to see in e.g. Xbox and Sony since they are both part of a larger conglomerate, but really obvious for nintendo.

You generally have a cycle of - "Launch": high marketing costs, low/negative HW margins - "Mid-cycle": lowering manufacturing costs, large game sales, high margin DLCs - "end-of-cycle": falling HW sales, fewer exclusives (-> preparation for next gen), fewer consumers (-> waiting for next gen). Here you usually have maximum profits since you don't subsidize HW and marketing is minimal (platforms are already locked in)

Generally you have to establish a big userbase during the mid-cycle such that you can levarage it during the late-cycle to be able to afford next-gen. Xbox has the big issue that their mid-cycle was catastrophic, which means they now don't have the console base to get into the next generation: If they have 3% margin _right now_ in the end-of-cycle where marketing and development costs are at their lowest, this does not bode well for the overall health of the business.

Specifically, your model now has two "correct" classes p(class=y|x) and p(class=⊥|x). This makes the results ambiguous. The way you resolve this is by adding in a cost of missclassification and a cost of answering wrong.

L(y, y') =

0 if y=y' l_err if y≠y' and y'≠⊥ l_⊥ if y' = ⊥

You can then estimate the expected error over your dataset. Notice that this now gives you additional degrees of freedom: Depending on how expensive answering wrong is compared to not answering at all, your predictor might be really bad or really good.

This means when benchmarking with a "no answer" action, you are often not actually benchmarking whether the model works well or not, but rather are benchmarking how well the model _happens_ to agree with the class-error weight you (implicitly) chose in your model.

The V100 (2017 -> 9 years old) can be rented from $0.02 to $0.37/h (right now I can find a V100 with a Xeon Gold 6140 and 48GB RAM for $0.165/h). Let's assume the guy you rent it to pins it at its 250W TDP and let's ignore the running costs of CPU/RAM/etc... Then you draw 1/4 kwh for that compute hour. The industrial electricity prices in the US vary between 7.5 and 25 ct per kwh (depending on state, time of day, etc...), so at 100% efficiency, assuming nothing ever breaks, and the CPU consumes 0W you earn about 14ct/h.

And remember: V100s hours are sometimes sold at 1/10th the price.

If I pick average conditions you need to start thinking of whether it is worth it to rent them out: Usually it isn't unless you have them anyways and just sell idle capacity.

It's barely worth it to run them in a pure "is it profitable" sense, if we also account for the opportunity cost of taking up a slot in your datacenter it seizes to be worth it really quickly.

Even for small CNNs you often need to do some quite complex interleaving of layers (i.e. running parts of layer 1 and layer 2 in parallel interleaved to take advantage of the downsampling of CNNs) to keep performance and memory impact reasonable (see e.g. https://openreview.net/pdf?id=2O8qbyxH6X).

Think more "image classifier" less "run an image to image transformer". For depth anything, a single layer's activation is probably significantly larger than the available SRAM (I think it is (224/16)^2 patches each with activations [48, 96, 192, 384] for depth anything small: You aren't running this.)

You still have no scalping, but you recover the ability to back out due to unforeseen events

From a theory POV you get softmax like distributions (Gibbs distributions) by trying to balance following some energy E(x) and the entropy of the distribution. In essence the softmax is the answer to "I try to follow the maximum of a function E(x) but I need to maintain some level of uncertainy".

The balancing coefficient between entropy and picking the maximum of the function is called "temperature" (following the behavior of particles in a physical system: The colder the system, the lower the chance of having particles randomly walk away from the minimal energy state).

specifically, the temperature is

softmax(x/temp)

if you draw temp->0, your softmax slowly becomes an argmax (with temp=0 being a literal argmax). If you increase the temperature, you are closer to the "random fluctuations" leaving more room for sampling x values that are not the maximum of x. (this is why e.g. LLMs become deterministic as you decrease temp->0)

Using a different base other than e implicitly changes the temperature:

N^x = exp(ln(N) x)

The normalization works the same since you are still dividing a positive value N^x by the sum of all alternatives sum(N^x_i), which is a normalization by design

In practice you use something like an exception monad, which makes this a lot more ergonomic since you don't need to carry a case distinction around for every unwrap: an exception monad essentially has an implicit passthrough that says "if it's a value, apply the function, if it's an exception just keep that". You only need to "catch" the exception if you actually need the value. I'm this case the exception monad is not that different from annotating a function with "throws": your calling function either needs it's own throws (=error monad wrapper) in which case exceptions just roll through, or you remove the throws, but now need to handle the exception explicitly (=unwrap the monad).

If you write this as a monad, your get very similar syntax to procedural code.

The equivalent for the US would be the consumption goods that are already flowing into the US. I.e. US gets goods but doesn't sell enough to Germany, so the difference to maintain the total exchange rate is the Gold.

That's also why it was trivial for france to repatriate its gold compared to germany: Germany holds about 10x the amount of gold in the US compared to France (France was ~120 tons, Germany is roughly 1200 tons: France earned its gold through different trade).

That's also why it is such a complex thing to repatriate German reserves: France took almost 1 year to repatriate its gold. For Germany, the efforts would be decade spanning (though maybe with recent changes there is a little more urgency).

There has been a recent (as in "18th of march" recent) petition to the Bundestag to repatriate the gold.

The reason not to repatriate the remaining gold back then is because Germany has substantial trade with the US, which is why Germany held gold in new york to begin with: It's the easiest way to resolve USD-Euro currency exchange at the central bank level (this is also why germany got rid of the paris gold reserves: with the euro you don't need currency exchange anymore).

Also, as you mentioned, the idea of "officially" repatriating gold with the current administration is quite dicey. It is very possible that the correct way of resolving this is to just stop buying gold in new york and let the currency exchange flux deal with the slow unwinding of the reserves without explicit repatriation.

It's not like the US has never e.g. openly threatened NATO allies with war: There is quite literally a standing law that allows the US president to invade the netherlands if any US military personnel is ever detained by the International Criminal Court. This law has been on the books for over 20 years and has the publically announced intention to prevent the US from being prosecuted for all the other atrocities committed in e.g. Iraq. This bill was supported by both democrats and republicans.

The reality is that the US' stance towards the rest of the world has not changed with the recent administrations (nor would I expect it to: Trump does not happen in a vacuum). What did change was willingness of the rest of the world to act on the US' actions.

The core insight necessary for chatgpt was not scaling (that was already widely accepted): the insight was that instead of finetuning for each individual task, you can finetune once for the meta-task of instruction following, which brings a problem specification directly into the data stream.
