<p>> But perhaps still useful for planning, as a starting place?<p>Yeah, lots of value in just having an app go "the mix you're trying to do is likely to fail the slump test". So you still have time to adjust the water ratio, or get better sand.</p>

<p>It is simply difficult to hide. You can just go and look at the infrastructure, after all. I bet almost all the information is from OpenStreetmaps, and people just walked around and added all the power lines, substations and powerplants they saw by hand.<p>And sure, you can bury the cables, or you can try keeping the output of your powerplants secret. But then the infrastructure nerds (or foreign spies) just count coal hopper railway cars per day and analyze cooling tower dimensions.</p>

<p>But why? What would change compared to 12 players on a huge map? Do you just want to conquer a large number of your neighbors and then still get to compete against other mega-empires?<p>When playing civ on 12 player maps, I still mostly interact only with the 3-4 that I directly compete with at any given time. I imagine that wouldn't really change with 100 people.</p>

<p>> Take care - the Hybrid battery can be expensive to replace and they do eventually fail.<p>That is true, but median mileage at replacement for the old NiMH batteries is 150k miles (240k km), and the lithium cells have a median mileage at replacement of over 200k miles (320k km) - even though those cars are now 10 years old, not enough of them have reached that mileages, so exact data is still not available.<p>And don't get me wrong, those cars are bullet proof. Median total mileage of the car could be a bit higher than 150k miles, especially after the car was sold to a third world country. But for most intents and purposes, those batteries (especially the lithium cells) have about the same median lifetime than the car itself.</p>

<p>If you want to make new helium, it's far easier to go the other way.<p>You just need quite a bit of Polonium, Thorium or Radon. Put it in a pool - and then wait a while. You just gotta collect what bubbles to the surface.</p>

<p>It's not automatically obvious. There could (theoretically) be domestic gas fields that are solely supplying pipeline "islands" (connected to domestic gas powerplants and fertilizer factories) under long-running contracts. Those should/would be more stable in price, since liquefying that gas and selling it elsewhere would not be trivial.<p>But in reality, that's not the case for any large US gas fields. They are all connected to the national pipeline "grid", and their gas can go wherever it is most expensive right now.<p>But it's the case for e.g. many Russian gas fields. They are much more segmented, and they have nowhere close to the liquefaction infrastructure necessary to export a significant fraction of their total output on LNG carriers.</p>

<p>Very simplified: farming and distillation is so extremely energy intensive, it's not clear whether producing one ton of bio ethanol fuel consumes more or less than one ton of diesel (or equivalent).<p>So producing bio ethanol is not a sustainability/ecology thing, it mostly gives farmers something to do.</p>

<p>It's the greed. Apple only makes around 8% of revenue through hardware sales of all Macs combined. "Services" (App Store, iCloud, Music, TV+, ect.) make more than 3x more revenue. Then, profit margin on services is again 3x higher than on Mac hardware. So they really want all Mac users also use Services.<p>If your proposed change increases Mac sales by 1%, but only 0.1% of users install Asahi, they lose money.<p>I'm still watching out for Asahi progress, amazing project. USB-C displays and the M3 will come (and I don't care to much for the rest), that makes a refurbished macbook air an attractive proposition.</p>

<p>>  my understanding is that Asahi has issues with: * USB-C Displays * Thunderbolt / USB4 * Touch ID<p>Valid. USB-C displays are on the horizon, the rest will take significant time (and might never materialize, it's difficult to reverse engineer).<p>> Because I don't like MacOS<p>Then spending thousands on modern MacBook will be a subpar experience, no matter how you do it. But yes, Linux will run OK inside a VM on a MacBook.</p>

<p>> Gemini was also unable to find the .dev, even in "Research Mode."<p>Unsurprisingly, right? Gemini just uses the same back end as Google itself, which - according to OP - doesn't list his site on page 1, not page 2 and not page 5.<p>Depending on the prompt, it should have gotten the link from the github, but that's like an indirect hint from a secondary source, it probably ranks the Google index quite highly when it does research.</p>

<p>Why would you want to do that? Do you like the hardware that much, and also that much more than just an M2 (soon M3) running Asahi?<p>Linux in a VM would work with the usual caveats. Periphery like the built-in webcam most likely won't work. Getting codecs and DRM to run will be pain and you'll be back to use macOS for that quickly (but that's just standard pain of ARM Linux).</p>

<p>> The apps don't just do that though; they call into and use an awful lot of the system APIs for user tracking / semi-native experience / biometrics and probably a whole host of other things. Its the incompatibility in these that drags compatibility.<p>Both can be true. Many (most?) online banking apps are just shitty wrapped javascript, that also uses an awful lot of system APIs.<p>I'm using a couple of different banks, and not a single one has anything close to a native app. Because how nice would that be?  Responsive interface (since it doesn't need to load every single view from the server), instant search over your transactions (since the DB can be cached locally), instant access to all the PDFs in your inbox... but no.</p>

<p>And they don't want to, because that experiment ran for around 20 years and resoundingly failed. Turns out it's really hard to stop the bottom quintile of users from entering all their credentials into just about any website that looks similar to what they are used to - and then their identity/money is just gone.<p>Stopping those users without a trusted authority deciding which electron-wrapped websites are genuine is an unsolved problem, I think.</p>

<p>That's the limit for continuous rated power. The motor's frequently have 600W-750W of peak power output, and can legally use this much for short amounts of time (usually seconds, like accelerating from a stop; but often also for going up a steep hill for several minutes).</p>

<p>No, what the modders do is just disable the velocity dependent power limit on the standard e-bike power controllers. The easiest/hackiest way to do that is to install a pulse rate divider on the tachometer cables - bike goes 30mph, controller thinks it's going 10mph and delivers full power. This messes up the mileage counter and is trivially easy for the cops to spot, but it'll work.<p>> The power levels required to push a hybrid bicycle to 45mph is north of 3000W<p>Yeah, 45 mph is hyperbole. 45 kph is very easily doable on a standard 750W e-bike motor with <$1 of additional electronics. At that point it's all aero, so going even faster is mostly about rider position and bike geometry (those scooter looking things are going to be slower than a proper bike on 29" wheels).</p>

<p>> Many e-bikes don't have torque sensors and instead use a cheap rotation sensor so the motor engages almost randomly at certain points in pedal rotation when moving at slow speed.<p>Today, those are mostly limited to Walmart-tier quality e-bikes. Even the very next step up (still big box store bikes) usually come with torque sensors.</p>
