  • You not going to break the loop till you pay dramatically more to teachers, poor pay usually attracts under motivated people in smaller numbers, so you cant be picky. These people eventually get promoted, an you end up with poor quality managers running the school who take advantage of good teachers.

    Its so self defeating as high quality teaching as you do results in better engaged students with better results that lead to life long improvement to the entire economy. Instead we have ladder pulling from the rich who want to kneecap state funded schools while enriching their own private schools to create a barrier for the majority to compete.



  • Lesson plans are like of bullshit paperwork, invented because a minority don’t do shit without being tightly monitored and a rigid structure to follow.

    Good teachers can just wing a class based on whatever needs covering from the curriculum on that day, bad teachers don’t care whats on the curriculum that day, terrible teachers don’t care and couldn’t even teach it without following a detailed plan.

    Its because of those two groups that lesson plans exist.

    In an ideal world you would just performance manage those two groups and sack them, but because teaching is underpaid there are a shortage of teachers (plus most people suck at putting people properly through performance management), so its beneficial to micro manage instead rather than having mass vacancies.


  • What subjects are you comparing it to? At its fundamental level math is a building block same way your native language is a building block to learn other subjects such as history or biology or cooking. I am splitting out language from literature the same way I would split Maths from engineering or physics, theory vs. application.

    I can only speak for English as that’s the only language I have ever really studied but for the average student whose native language is English you simply do not need to study English language to the same level as somebody looking to apply Maths to Biology or Physics to a advanced high school level. You simply do not need to do this to the same level, high school English language simply isn’t as deep a subject. High school literature is potentially, but again, that’s application not theory.

    On top of this, you use English far more often than Maths both in school and out of school. Average kid isnt going to use much Maths day to day other than wondering about basic fractions for sharing a pizza/cake, or simple addition/subtraction for pocket money type stuff. Sure, there will always be exceptions but I am talking about the majority.






  • Only touch screen controls for important controls are a safety hazard, and the upcoming safety standards in the EU will withhold the top ratings because of this: https://etsc.eu/cars-will-need-buttons-not-just-touchscreens-to-get-a-5-star-euro-ncap-safety-rating/

    Controls for things like the radio or cruise control are fine on the wheel as buttons. Indicators absolutely aren’t, and are the example I used for good reason. Honestly I have no words if you cant see that they are an actual safety hazard on something like a roundabout, particularly one you would navigate at speed.

    Simple left or right turns at say traffic lights or other junction aren’t the problem, trying to activate them while the wheel can be at some random orientation is difficult, so you end up not bothering.

    Not signalling when at a round about is an offense in the UK. Its rarely enforced due to lack of traffic police, but its enough that its an actual offense that the car should be designed not to make it considerably harder to use them. In the event of an accident serious enough for the police to get involved if you didn’t indicate then that’s going to count against you.


  • Which ones aren’t? Also deciding to copy dumb ideas from elsewhere is even more dumb as someone else did the alpha testing for you, showed it was dumb, and you still copied it.

    I forgot the yoke instead of a wheel. That’s another Elon special.

    Buttons for indicators I know are on modern ferraris, I can’t afford one but I still wouldn’t buy one because of them. Try using buttons on a steering wheel when doing a right at a roundabout, just the dumbest shit.


  • BYD is eating everyone’s lunch at the bottom not just Tesla.

    Tesla could have prospered by sticking to the mid range but their build quality is appalling even for a lower mid car.

    Couple that with some truly dumb design ideas from Elon (no lidar, no physical buttons, indicators as buttons, stupidly high repair bills due to design choices) and some even more stupid personal behaviors from him and he has just cut the legs out of his market.

    EV buyers who are spending more money care about this kind of thing, budget buyers it is mostly about price.


  • With a thermostat, smart or dumb, you set a target temperature and a time. With a dumb thermostat it waits till that time and then activates. With a smart thermostat it should learn how long it takes to heat or cool to that target temperature in certain conditions and then aims to hit the target at that point.

    So if you got up at 8am and wanted it 20c with a dumb thermostat you got to work out when it needs to go on in order to hit that as no heating system is instant on something the size of a house, with a smart thermostat with learning you do not need to do that at all, just set it for 8am.

    As no system is working in a vacuum how hot or cool it is outside, even how sunny it is, has a big impact on how quickly your system heats or cools. Being able to measure and compensate for the outside temperature means the actual start time can be adjusted for you. This can save significant amount of cash.

    As an example, lets say the outside temperature was going to be -10c 6am till 8am and you wanted it 20c by 8am. Doing it with a dumb thermostat you would either have to live with an under or overshoot on temperature. Say next day its 2C, now you need to adjust your overshoot again. With a smart thermostat I do not need to do that at all.

    Sure, you can just live with the under/overshoot, but its better for your bills and better for the environment not to.

    I prefer zwave and zigbee because they give me 12 months plus on small batteries, and I can not get this on WiFi devices. This greatly improves where I can install sensors and the like.

    Even when I have a larger battery, such as the 60ah battery I use for my back garden lighting, I still use them as it reduces power draw over a WiFi controller.

    I can also directly connect them to smartthings and more recently home assistant thst I have migrated to rather than connecting to a WiFi device via a Web service. This improves reliability and speed on average.

    I get no problems with running a large network of such devices, I have over 100 bulbs, relays, plugs, and sensors that are connected. My WiFi is decent and supports 8 nest cams that are outside plus another 20 or so devices that are inside, so it offers a similar range for me.

    Levers can be the ultimate for long lasting as virtually zero parts to wear out especially the ones that require you to heat up the water yourself, but I would struggle to recommend one to someone coming from a bean to cup due to the difficultly factor. My first espresso was a Flair, having to get the temp, speed, and pressure consistent every time for every shot at 6am in the morning was a complete PITA on top of getting the grind, temp, and weight right for that shot. I soon switched to an E61 as its just push button in comparison.

    Long term I want a lever like the Strietman CT2 but not till I get a Decent for everyday use.
