Pretty much what I meant. AI becomes a lot less magical when you realize that its all taking output of some ML algorithms that are basically doing dumb pattern matching/statistics and then making decisions on it, usually without even some sort of model of the current state of the world.

I'm assuming Zuck understands this and Musk is engaging in magical thinking. I find that detractors of ML somewhat underestimate what it can do, and the AI cheerleaders vastly overestimate what it can do. The detractors are at least closer to reality.

this is mostly true, but there is some interesting stuff going on in characterizing what you can actually get deep learning to do (and the many things it can *not* do), e.g. https://arxiv.org/abs/1608.08225

the outcome will no doubt chill the current optimism a bit, but the deep learning stuff does solve some problems very well, so in the long run it will probably be extremely helpful to figure out where it is applicable and not. obviously even the actually promising self-driving transport (e.g. little electric waymo shuttles for airports/campuses/pedestrian areas, for e.g. handicap access, controlled environments where being very conservative is appropriate anyway) involve a lot of actual expert system-style work, and reasonably clearly a lot of that work is still happening in a very unsystematic way, but there could be a legitimate resurgence of research now that the learning side can provide fairly robust means to understanding and interacting with a slightly messy reality

pretty much any of the mid-to-high tier zojirushi rice cookers are /amazing/, i love mine. make sure you get the induction version, the resistive heat one works... alright. induction heat blows it out of the water. does a lot more than just rice too, between that and the timer function you can set up a meal to be ready when you need it. thats the one gotcha, the timer function is 'i want this to be ready at' not 'i want you to start at', which tripped me up till i got used to it. they also make some combo rice cooker/pressure cooker thing that i want but not bad enough to scour craigslist for.

and yes, make sure it has the 'fuzzy logic' sticker on it, the other ones are just dumb timer/weight sensor cooking, /maybe/ a bit better temp control than the heating coil/ptc combo the cheapy cookers use.

i still don't understand why they made the drat bumper a critical structural part of the car. does anyone know what their stated reason is for this? i could never own a car where I'm terrified of doing things such as "parallel parking" and "putting the car in reverse, ever"

I showed the picture to a friend who works in the structural design dept. And he send me this (translated from German)

quote:


The plastic part is just the optical exterior. The energy absorption happens below.

There are 3 types of scenarios for rear end collisions that, in a well executed design, will limit the damage done to the vehicle components in an escalating manner.

The first layer is the exterior bumper itself. This part is important for zero energy, zero torque collisions. You will find such collisions typically as roll out collisions when the driver intends to bring the vehicle to a stop and underestimated the total length of the car. The main damage depends mostly on the contact geometry. Rear bumpers have a low surface curvature. If you get lucky and hit a low curvature surface too, there will be no structural damage at all and just paint imprints. If you hit a pointy or highly curved object you might damage the structure of the bumper, but not penetrate it or damage the secondary and tertiary impact elements.

The second impact element depends on the vehicle design and market execution. The US market demands that since the 70s a 5mph crash may not impair the functionality of a car. Nowadays due to generalization attempts, the same usually holds true for most internationally sold vehicles. In order to limit the damage in these low energy collisions, cars include a Hohlraum (cavity) between the exterior bumper and the rear end of the main impact structure, which nowadays usually is an aluminium extrusion profile in a beam shape. The cavity is filled with Styrofoam usually in order to absorb the energy of the impact while the Styrofoam crumbles. The exterior bumper and the cavity filling will inevitably have to be replaced afterwards.

Here's a picture of the front bumper and low energy impact absorber executed as a Styrofoam cavity filling



The last impact mechanism are high energy impacts. Under these conditions, the crash scenario moves from a nuisance to a safety and health related event. The energy absorbers for these types of impacts are usually metal domes wirh defined deformation properties or in case of special requirements, aluminium honeycomb, that absorb the impact energy that is induced into the metal bumper structure. The goal in designing these elements is always to limit as much damage as possible to the crash elements while maximizing the energy absorption up to the breakthrough point, at which the main structure of the car will take damage. This will usually mean that structural damage does not occur until the crash element has been fully deformed. In order to ease diagnosis of crash damage, the elements are layed out to deform inwards, so that a simple look at the deformed length of the element will give an information about potential structural damage to the chassis.

Here are some examples for automotive crash elements and their deformation.







As can be seen in the first of these images, the actual parts containing the crash elements can be more or less easily separated and replaced from the safety cell structure/ chassis/ monocoque of the vehicle. The rear crash elements may be welded to the car body, but can be ordered and replaced individually. This is by design obviously since a significant number of cars will sustain impacts that trigger a deformation of these elements and irreplaceable crash elements would lead to a severe increase in insurance cost usually.


The only logical conclusion is that tesla neglected the execution of the secondary impact layer in a way that the rear bumper developed weak spots that will trigger the crash elements at low energy impacts AND designed its crash elements in a way that makes it impossible to service them. This is a cardinal sin in the making of vehicles for the mass market. The only cars that are generally made wirh irreplaceable crash absorbers are carbon fiber monocoques for motorsport applications since you can reach higher energy absorption rates and endure crashes at really bad angles.

For the mass market a damage to the safety cell structure or the chassis of the vehicle at the deformation rates the tesla in the picture endured is practically unheard of.

a rice cooker cup isn't an imperial measure cup fyi

quote:

the measurement is 1-gou, slightly more than 180ml, which, by no coincidence, is also the typical measure of a wooden sake, cup, and is closely associated with a historical sake bottle size (approximately 1.8l)

http://en.wikipedia.org/wiki/Masu_(Japanese)

It turns out that this amount, 1 gou of dried rice, neatly corresponded to a typical serving of rice. In practice, most contemporary Japanese eat about 1.5-2 gou per day; 1 gou of dried rice cooks up enough for 2 Japanese adults for one meal if you have several side dishes. There are other measurements that derive from the gou (or perhaps the other way around), such as the koku, which was considered the amount of rice that a single person would consume over the course of a year.

This is one of the human-centric forms of measurement that has survived the metric push; you can find various examples of this in many otherwise metric-converted countries. It turns out some studies show that those metrics often make certain categories of estimation easier for people.

The only larger scale body repair on an EV that I witnessed was on a 2018 Nissan Leaf (rear right impact) and the whole process was fairly straight forward and comparable to a classic automotive body repair (total repair cost was about 8000€) the only exception was an added week of delay to drive in a Nissan EV tech to disconnect the HV system before the welding could commence.
