  • I drive an ancient (2012) EV.

    I’m content with a stick shift, but the functions I want are:

    • reverse
    • neutral (coast without regen, allow car to be towed, only mechanical brakes)
    • regenerative brake level 1
    • level 2
    • level 3

    …and that’s all, and I have them. I don’t need acceleration performance to change, much safer to have it always consistent. It’s the default braking performance I need to alter, because sometimes you go downhill and sometimes it’s icy.

    They’re electronic, no mechanical pushrods needed, but my car’s manufacturer, in the dark dawn of electric vehicles, could not understand that and used mechanical pushrods. :D

    A function that is mechanical and which I would like to remove from my car’s gear stick and place under a separate switch is the “gear lock” function. It’s like a parking brake without engaging brake pads. It’s useful, but having it under the stick creates a nozero possibility of engaging it in motion - it shouldn’t be there, but under a protective cover or protective circuit, elsewhere.


  • The cause is uncertain for now.

    It’s known with certainty that polar ice did not exist then - so it was not Antarctic melting giving a feedback bump. Besides the feedback bump caused by Antarctic melting is speculated to be on the order of 2 degrees.

    It could have been partly volcanic, but not mainly volcanic. It certainly wasn’t tectonic, as the event was a brief spike of “only” ~200 000 years.

    The study below, somewhat speculative in nature, proposes that bottom water warming occurred 3000 years before the carbon trip, and decomposition of methane hydrates could have been the amplifier of the process. Which, to me, suggests that maybe the cause was geological.

    https://pubmed.ncbi.nlm.nih.gov/18097406/

    A hypothesis referenced in Wikipedia: a lot of high-carbon rock (kimberlite) experienced a volcanic eruption that released much CO2, and brought oceans above the theshold where methane hydrates decomposed and supplied methane.

    Although the cause of the initial warming has been attributed to a massive injection of carbon (CO2 and/or CH4) into the atmosphere, the source of the carbon has yet to be found. The emplacement of a large cluster of kimberlite pipes at ~56 Ma in the Lac de Gras region of northern Canada may have provided the carbon that triggered early warming in the form of exsolved magmatic CO2. Calculations indicate that the estimated 900–1,100 Pg[194] of carbon required for the initial approximately 3 °C of ocean water warming associated with the Paleocene-Eocene thermal maximum could have been released during the emplacement of a large kimberlite cluster.[195] The transfer of warm surface ocean water to intermediate depths led to thermal dissociation of seafloor methane hydrates, providing the isotopically depleted carbon that produced the carbon isotopic excursion. The coeval ages of two other kimberlite clusters in the Lac de Gras field and two other early Cenozoic hyperthermals indicate that CO2 degassing during kimberlite emplacement is a plausible source of the CO2 responsible for these sudden global warming events.


  • Stop bluffing, unless you know what it takes to get an organ successfully transplanted to someone. And I see you don’t.

    A really simple rule: if one would intend to get transplantable organs, one would not drop construction material on the person. One would transport the person to a hospital without any delay. Doctors would be the persons telling of which violations are happening.

    As things are, both Israel and some other countries (Russia) have the habit of returning the bodies of some prisoners who died under suspicious circumstances without some organs. For example, an Ukrainian journalist’s body was returned without her brain and throat. No, she’s not living in another body, brain transplants are fantasy. She was likely strangled to death and organs removed to conceal torture.

    I am currently under the impression that this practise serves the purpose of concealing torture (or other crimes) in several places, with one exception - China.

    China has been credibly accused of actually harvesting organs from prisoners executed in prisons. This is feasible for them, since a prisoner after execution can be tested before they are killed, and is immediately available for dissection and cooling of organs, which can then be rushed to an airport for sending to the correct hospital. I have good reason to suspect it’s happening. Needless to say, it’s an extremely serious crime.

    However, I have not heard of any successful (no matter whether voluntary or forced) organ donation from a person who experienced circulatory death in field conditions and was transported slowly from a considerable distance. Jenin is in the West Bank. Do you think doctors in the West Bank would accommodate a request from the IDF to remove, test and cool organs for from a shooting victim for transplantation? I don’t think even Israeli doctors would.

    If you think differently, I would like to see evidence.

    As the thread tells us, IDF committed two war crimes: shooting prisoners and desecrating their bodies. There is no need to spread silly rumours on top of that. Reality is bad enough.




  • If they had something to fight for, I think they would.

    In reality, they have Maduro (who has suppressed a popular uprising against himself, and likely didn’t win the last elections) and 20% of inflation per month.

    If the US does attack, predictably, only hardcore fans of Maduro will oppose. But the force that Trump has sent is not capable of occupying Venezuela, only striking it and incapacitating the government.

    But an attack is an attack - if Trump does order an attack, I have free real estate to sell him… in the Hague, because international agression is prohibited.

    Personal suspicion: maybe in Alaska, one man told another: “you can get Ukraine” - “and you can get Venezuela”. One of the men may think he’ll get Caracas in 3 days and will be met with flowers. The other guy may hope that Caracas looks like Kyiv, which he’s been “getting” already for 3 years. But I doubt if Caracas looks like that.

    Regardless of what will happen, the story about narco-terrorism is hot air. Smuggling is not war. Smugglers can and should be arrested, not bombed with drones. If this becomes a cause for war, then war will be based on fiction and lies.


  • The background: Ukraine didn’t have 30 years to refine its cruise missiles and long range strike drones - they built them in 3 years.

    There are many ways to make a missile navigate.

    • it may follow terrain features (hard, you need to thoroughly map a country using a fleet of satellites)
    • it may take readings from a satnav system (this can be jammed)
    • it may scan for mobile phone towers and match their ID codes to a map

    Once a missile has the direction of 2…3 towers confirmed, it knows where it is - and where to go. Crashing into the final target uses machine vision, but getting there does not.

    As a result, Russia tries to counter them by shutting down mobile networks. Not sure if it works. Going by the news, doesn’t seem to work very well.

    As for how to avoid exfiltration of mobile network data - hopeless. People have so much spyware and crap on their phones that you don’t need to put an agent on ground to get a list of towers. You just buy out a smartphone app from a shady supplier and develop it into a rootkit, or sell rooted phones on the cheap in the target country.





  • As long as a car isn’t open source, a car maker going out of business is a big problem. It’s going to leave customers stranded without spare parts.

    That, in my opinion, fully explains the propping up.

    And for this reason, I predict that they will be keeping even unprofitable manufacturers on life support despite everything, quite long. The companies will likely get merged and production of spares will hopefully be arranged. If not, lots of people will be angry.


  • Eventually, you do need to.

    My electric car (from 2014) has other stupid features, but at least, no electric parking brake. Rear pads were obviously very thin by now, and most likely the previous owner also changed them once. So I went to a self-service workshop last spring, brought along spare parts from a shop across the road, replaced them.

    Annoying part: drums came off relatively poorly, the new pad set needed treatment with a disc grinder (allegedly compatible part, but a tiny bit of metal was 2 mm too long).

    When the time comes and my factory made car wears down, I intend to build another DIY e-car, as I’ve done twice before.



  • …and some return, too.

    Ukraine is notable in one way: it does not draw up people under 25 years for war (so far). It trains them, it lets them volunteer, it welcomes if they build technology for war, but it doesn’t order them to go.

    What the reasons are, I’m not totally sure, but I think the government and Rada might want to avoid creating a “lost generation” where many experienced wounds or trauma in youth. The generation they are attempting to spare is a weak spot in Ukraine’s population pyramid - relatively few people were born between 1999 and 2004. If that generation has considerably less kids than generations before them, there will be a pretty bad population decline coming.

    Of course, some fear that under pressure, government might cave in and start sending increasingly young people to fight. Others meanwhile fear that many will move abroad and never return.

    I’m not sure what to think about it. But I’m pretty sure a person just out of school isn’t the best candidate for war. Physical fitness is less important today, but psychological stability under pressure is required.




  • Here in Estonia, you sometimes wait for a ChaDemo cable to become available.

    The operators of charger networks forbid hitting the red button (emergency disconnect) under any conditions unless it’s an emergency.

    There’s a silent agreement among drivers that lack of charging opportunities is an emergency. :D If the other guy is not present and their battery has reached 80% or more (charging has slowed to a trickle and they have enough range to drive), it’s considered OK to hit the red button and hijack the cable.

    But alas, some cars (guess which, the ones without door handles, specially designed for suicidal drivers) sometimes won’t release the cable.

    You also frequently call customer support to restart chargers and watch Linux boot messages scroll by, and complain until blue in the face about specific chargers that stop working for some specific cars in cold weather.

    In short, it’s pretty close to a mess. :o
