  • The problem is that they did not build battery factories quick enough, they sat on their hands waiting for massive hand outs to pay for the factories rather than investing. All while profiting off existing investment in ICE that is high return at this point in its life cycle. So they ended up making more profitable per unit halo models like the F150 that they do not need to sell in high volumes to get a return on.

    Batteries are about half the raw cost of an EV, if you paying somebody else to make it for you its going to be more expensive as they will want to make a profit and you are stuck being able to buy ever how many they want to sell you. In practice they have ended up funding a competitor to develop battery tech as well.

    Lowering battery cost is the secret to cheap prices, you cannot truly compete until you make your own batteries in high volumes.




  • I use powershell for work as I need the m365 modules for work and its very flexible with decent module availability to plug in all sorts.

    However it absolutely sucks for large data handling, anything over 10k rows is just horrendous, I typically work with a few million rows. You can make it work with using .Net to process it within your script but its something to be aware of. Being able to extend with .Net can be extremely useful.


  • I switched from Pop OS tiling that I had retro bolted onto stock ubuntu to Sway, massive step up and more importantly I get to keep my Ubuntu/Wayland base.

    As with most add on WMs I had a bit of a learning curve sorting out the extra bits and pieces that just come stock as part of Ubuntus Gnome implementation such as a launcher (I use dmenu), a menu bar (swaybar for me), and even a lock screen (swayidle). Even doing things like wallpaper needed more effort.





  • Normal hifi gear, particularly second hand can sound way way better than generic computer crap. However normal hi-fi speakers are designed to work best a certain distance from the wall **and ** a certain distance from you. These distances vary between speakers but it is important to check this before spending any cash as some speakers need to be many feet from you, which isn’t always remotely practical for most pc setups.

    I went with Dali Minutes for this reason, so they can be right on the wall and really close to me. I paired mine with a Rega Brio amp and RME ADI 2 USB DAC, then added a monitor audio sub later.

    Most proper studio monitors are designed for near field listening they also make a good choice although they can be a little clean for some people’s taste.


  • I use powershell by default on windows and I prefer it for scripting any day of the week vs. shell scripts. It’s not the fastest but you can always plug in .net to your scripts to dramatically improve performance. Sure, I could write the script in rust or whatever to make it even faster, but that’s way more work than I need for the lifespan of the script.



  • And again, I don’t see that it applies at all to what is a parts tracking system, its not a maintenance plan, a direct safety system, operational guidelines for engineers or anything else you are falsely trying to make it.

    You keep describing the maintenance schedule, which is again, irrelevant to tracking the history of parts. Age of the system is also irrelevant to the problem here, a system outside or inside its operational life span can still have shitty black market parts fitted to it making it more unsafe than using the correct part.

    The airline industry in particular has been hit with a number of planes being fitted with bogus parts, this is despite all of the things you talk about, they have not worked for tracking parts and proving their provenance. Hence, a more robust system is needed.


  • I am intentionally not accounting for it, as its irrelevant to an end to end parts tracking system.

    Your difference is only really relevant to the standards that the part is made, the safety systems the vehicle needs to have including redundancy, and the frequency and depth of the maintenance schedule.

    Both need to be able to prove that shoddy third party parts haven’t been fitted, that the parts have been replaced on schedule, even if the quality of the parts and the frequency of replacement is completely different.


  • While parts don’t need to be made to the same standard nor do you need the same depth of safety components, I completely disagree that we should not be applying the same hygiene to part province and maintenance schedules. Obviously this should apply to track side components such as signalling, the track etc. as well, just like it should for the parts of an airport that a plane will interact with.

    Avoiding utter maintenance shit shows like the train crash in India that killed 300 people seem just as attractive to fix as they do with planes. Or the toxic spills that America has had that may not have killed as many people but are still expensive and hugely disrupting.

    Part of getting maintenance schedules followed properly and using quality parts is right to repair, part availability, and being able to prove part provenance and quality. A method to audit a part is essential for this, if we do whats needed by allowing 3rd parties to make parts to original spec for a reasonable cost, like we should to lower cost. Lower cost, more chance companies will avoid cutting corners, particularly if there is a proper audit trail for the part and you can actually prove that it is the *part *as well.



  • Agree with you about the level of standards, there needs to be some for train and bus parts but not to aircraft standards.

    I also agree any part manufacturer to be audited to which level they are working at and prove a chain of custody for that part. They grey and black markets need to be squeezed out as much as possible, obviously you have to give the end customer, airlines, rolling stock owners, etc. a cost incentive with right to repair to honor the system. As any system can be hacked or broken with enough of a cash incentive.

    I think the OEM having to license, at a reasonable cost, the exact spec and design for a part to third parties is an important part of any right to repair. You cannot self repair if you cannot get replacement parts for a reasonable cost.





  • Its also a terrible way of reducing charging time for anything that doesn’t have an enormous battery like an electric Lorry/Semi. Even then its like 30 minutes for 70% charge for the Tesla Semi, which is roughly the same as a mandated break anyway for the driver.

    What is more useful is making sure all EV batteries are easily swappable by third parties as this will massively extend the lifespan of EVs if you do not need to go back to the main dealer for a much marked up battery replacement when the cars battery stops holding a useful amount of charge past the 10 year mark.
