  • Android dev of many many many years here.

    Android Studio with Jetpack Compose.

    I’d also suggest you try doing kotlin multiplatform. You can take your Android app and end up with a iOS app, and if you want, a desktop app. You would need a Mac for the ios app eventually, but not for the desktop apps.

    There is minimal work to get it set up to start, they provide a wizard, and there are a lot of libraries available now that are multiplatform.

    IOS and Desktop are both considered stable now, but the iOS beta was pretty solid.

    All the apps it generates are native apps.

    Even if you don’t want to do multiplatform to start, if you use kotlkn only libraries that are capable of it, you could easily switch to it in the future if you wanted to as it’d be structured properly from the start.

    E.g for libraries if you use Koin instead of Dagger2/hilt you could switch to multiplatform in the future without much effort. If you chose dagger instead, it’d be a big task to switch. And if you start it as multiplatform but Android only, you’ll know which areas still need implementation work later to eventually work on iOS.



  • A thing would need to officially be a flop to be considered squandered like the Cybertruck is looking like.

    They might have a few failures ahead of them yet though, but you can’t call a mid flight project squandered.

    Edit: e.g part of that loss could be attributed to them finalizing and now starting production at the megapack factory at Shanghai. Short of Elon backlash stopping sales of their commercial batteries, that won’t be squandered and will make a billion or two or three in profits this year.




  • The article doesn’t say they’ve never made a profit on any of their cars. If that’s what you got from that, you should try reading it again.

    Also, if you make 1 billion in profit on something, and then spend 2 billion researching and developing and setting up a factory to build a new product, you end up with a loss of 1 billion. That does not mean your first thing is unprofitable. This is pretty basic stuff.

    The vehicles are profitable, they just didn’t provide enough profit this quarter to cover their R&D and capital expenditures for growth.

    Edit: Sorry, and in case it wasn’t clear, their R&D and capital expenditures dwarf the ZEV credits every quarter.


  • Not a single tesla vehicle has ever been profitable as an actual vehicle.

    This honestly couldn’t be further from the truth.

    Tesla’s vehicles once ramped have always been extremely profitable (except probably the CyberTruck as it hasn’t properly ramped due to low demand)

    Any losses you see are due to their aggressive growth involving capital expenditures and research and development. It’s not that the vehicle isn’t profitable.

    The ZEV credits are just bonus money that they can then leverage to expand faster.

    Edit: If you want to try and see this another way that might make sense… The Model S and X were very profitable, but they didn’t make enough money to fund the expansion for the Model 3 and Y. Ditch the Model 3 and Y, and remain a boutique luxury car company, and they would posted profits instead of losses. It wasn’t the cars losing money, it was the growth. The ZEV credits accelerated that growth immensely by giving them more breathing room.


  • There are other electric semi trucks out there, but none (at least as of last year) compare in specs and capabilities. The big issue is their power consumption is much higher than the Tesla Semi which has been repeatedly validated by their testers as even better than what Tesla advertises. Efficiency will be king in this kind of business.

    Worse efficiency = less range = more batteries = less load capacity = less money per delivery

    E.g this is from DHL

    https://www.dhl.com/global-en/delivered/responsibility/dhl-tests-tesla-semi-electric-truck.html

    Over a two-week trial period this summer, DHL Supply Chain USA took a thorough look under the hood of the Tesla Semi, integrating the e-truck into 3,000 miles (5,000 km) of normal operations out of Livermore, California. The trial included one long haul of 390 miles (625 km) – fully loaded with a gross combined weight of 75,000 pounds (34 metric tons) – confirming the Tesla Semi’s ability to carry typical DHL payloads over a long distance on a single charge.

    During the trial, the trial vehicle averaged 1.72 kWh/mile operating at speeds exceeding 50 mph (80 km/h) on average for over half its time on the road. The result exceeded our expectations and even Tesla’s own rating.

    Putting the Tesla Semi to the test allowed us to validate whether it could travel 500 miles with a fully loaded trailer and see what our drivers thought of the truck’s performance. We were encouraged by how quickly they gained confidence with the vehicle and leveraged the Tesla’s smart features to help improve performance, comfort, and the overall driver experience.

    Edit: Just some examples… I don’t know if these have been verified in use unlike the Tesla, so all theoretical based on the advertised miles/battery size.

    • Mercedes: 1.935 kWh/mile (310 miles)
    • Kenworth: 2.5 kWh/mile (200 miles)
    • Volvo: 2.05 kWh/mile (275miles)

    And those are all shorter range at that.

    Edit: I should also add… we don’t know the price of the Tesla Semi. Its possible that its ridiculously priced and the increased efficiency is negated even over the life of the vehicle compared to the other trucks. That’s a big unknown given these are pilot vehicles.











  • A lot of what people have heard about being one of the least reliable cars is from the mandatory inspections in Germany.

    If there’s any rust on your brakes, the car fails the inspection. Teslas have some pretty aggressive and good regen/one pedal driving so people don’t use the brakes often. You’re supposed to use the brakes with some heavy braking to help clear it over time. People don’t do this, they take the car in, and it fails since it has some rust on it. Just using the brakes would clear it though.

    The earlier Model 3 also had a problem with the front suspension which could cause a fail, there’s a service bulletin on that one.

    The Model S also had some air suspension issues, but from my understanding, who doesn’t have air suspension issues (but I might be wrong)

    Take those things, add on all the other small quantity issues, and it was ranked one of if not the worst vehicle the 1st year they were coming up to the age inspections were required.
