Tracking an aircraft carrier should not be difficult for any state (satellite images). The fact that civilians can do it too now is interesting.

It would be another matter if that was tracking a nuclear submarine...


No, this is notoriously difficult. The earth is vast and a carrier is tiny in comparison.


Difficult 40 years ago maybe.

I can't imagine with the satellite image and compute we have it would be difficult at all to know the real_time +- 30min location of any carrier by maybe the top 5-10 states, even at night.


Commercial satellites can get 30cm resolution images (military satellites can likely get even more high resolution).

The earth is vast, but once you pinpoint a carrier, a simple software loop should be able to track it for ever (those carrier do not move fast).

I cannot imagine this being remotely difficult for a state to have a constant pin on every large carriers sailing on earth. There even might be some civilian apps for that too.

But again, Strava and other connected + geolocation apps have been an issue for military personnel in general.


Sub wouldn't get a GPS signal, luckily.


You mean the thing that launched in 2023 and that is still not widely deployed ?

My BoA still prints checks and mail them to the US Bank across the street when I have to pay my HOA. So yes, why not FedNow... BoA and USBank ?


In US also... but here in US, my bank (Bank of America) would print a check, put it in an envelop, send it to the other bank (e.g. US Bank). So, it is not instantaneous, but it is still free.

The drawback is when the US Bank office down the street that hosts the account closed for water damage, it stopped receiving the checks, and it took forever to bounce, so I had no idea that I was not paying my HOA... And this happened in San Francisco, California where the Bank of America and the US Bank are on the same street, a block away...

I cannot wait for FedNow or anything trying to fix this mess.


Well the cap is only on the interchange fee, there are several other fees to add to it... example: https://www.adyen.com/pricing

Processing a Mastercard card is "$0.13 + "Interchange+" + 0.60%" where the "Interchange+" would be 0.30% for EU. So more like €0.10 + 0.90% so for €10.00 product, it would be €1 of fee (1.00%). Much less than here in US, but still not negligible for small businesses that run on thin margins (and 20% VAT).


Looks like you missed a decimal. 0.9% of 10.00 is 0.09 so the fee is 0.19 euro on a 10 euro purchase.


the "2% cash reward" and "miles" etc. is common here in US because our cards charge the merchants already a lot. So sure we all overpay everything in US because of the credit cards, but we get a small piece back.

Now, would it be nice to not overpay at the first place. Technically we could re-implement the whole thing (instant payout, fraud detection, etc.) like Brazil or India did. It would bring more than $100B back to the US consumers every year, that could be spent elsewhere.

Monopolistic practices prevent competitors charging less from arising.

86% is small?


Same holding on the 13 mini, love the form factor.


Did some modest development on Lambda Prolog back in 1999. I still have a vivid memory of feeling my brain expanding :) like rewiring how I approach programming and opening up new territory in my brain.

It might sound weird and crazy, but it quite literally blew my mind at the time !


That is what self-driving car should eventually use, whenever they (or the authorities) deem their model good enough. Burn it on a dedicated chip. It would be cheaper (energy) to run, and faster to make decisions.


It's more expensive in COGS and self driving doesn't need to run at 900 Hz.


And to some extent, I also drive with my ears, not only with 2 eyes. I often can ear a car driving on the blind spot. Not saying that I do need to ear in order to drive, but the extra sensor is welcome when it can helps.

There is an argument for sure, about how many sensors is enough / too much. And maybe 8 cameras around the car is enough to surpass human driving ability.

I guess it depends on how far/secure we want the self-driving to be. If only we had a comprehensive driving test that all (humans and robots) could take and be ranked... each country lawmakers could set the bar based on the test.


The other day I slammed the brakes at a green light, because I could hear sirens approaching -- even though the buildings on the corner prevented any view of the approaching fire trucks or their flashing lights. Do Teslas not have this ability?


I don‘t know whether Tesla‘s self-driving mode could do that.

However, notice that deaf people are allowed to drive, ie. you are not expected to be able to have full hearing to be allowed on the road.


Nuanced point: Even if vision alone were sufficient to drive, adding sensors to the cars today could speed up development. Tesla‘s world model could be improved, speeding up development of the vision only model that is truly autonomous.


I do not think they store any biometric data, they just compute a key out of the image. So, those keys are useless. Very difficult to create a fake living hand with all the living blood vessels with just a key.
