English ivy is a ground spreader, at least where I live. It won't grow on the ground if it gets a lot of sun, but ground shaded by trees will turn into a thick mat that is impossible to pull up. Some yards have it growing as a ground cover in the flower beds. You can't pull it off walls or the ground easily. It grows tendrils (roots?) into anything porous, which makes it extremely difficult to pull up. If it's growing on the ground, it's just a thick mat that is impossible to pull up. And while I wouldn't call it a fast spreader, if you ignore it for a couple of years, it will start to take over.

Source: I used to work for a yard company, and I have it in my own yard.

Toyota does make seals (Koyo), bearings (Koyo again), and forgings (Aisin). Dunno if they roll their own steel, but would be surprised if they don't.

I've sold lots, some of which were obviously chopped out of vehicles with a sawzall (vehicles that I legally owned, btw). They've always scanned my ID, took my thumb print, and mailed me the check after a couple of days.

I had a math professor who I'm pretty sure was borderline autistic. His son actually was autistic. While he wasn't the best math teacher I've ever had, he was very good. (Didn't help that I can't comprehend delta-epsilon proofs.)

> My last post was about either How to transport a convex object on a camel or Android Studio’s “Code contains easter egg” inspection. Find out which.

I realize one option is supposed to be ludicrous, but based on this post, either option is possible.

That was true 20 years ago. The question is how much do you ease up the brake on that specific wheel, and then how much do you reapply it? You need to know the coefficient of friction of the road to know this. Modern controllers are doing a physics simulation of the entire vehicle, and part of this is the weight transfer as you go around a corner (which is partially influenced by the CoG). They then do a physics simulation of the hydraulic brake circuit so it knows how long to run the pump to build up the desired brake pressure.

Now of course this is combined with stability control (since that is required by law) and both of them are controlled by the same code.

(On a related note, I've spent way too much time reverse engineering the calibration for the ABS for a Silverado truck. Ridiculously huge program, ridiculously complicated, and I have a sneaking suspicion that the source code is a mess.)

I was woken up by my neighbors Dodge Charger 11:00 last night. There's a special place in hell for these fuckers.

Or, like my wonderful neighbor, want to remove their muffler to show off how awesome they are.

More seriously, a successful electric car needs a chassis that's been engineered to be an electric car. You can convert a normal front engine, rwd chassis, but it's always a compromise.

Visually? Really? Didn't know that. I only own and work on old vehicles, and those all have a float with a magnet that triggers a reed switch.

> and a software patch that lets a driver know if their brake fluid reservoir is running low.

You mean like every single other vehicle ever made? I thought this was a law. Also, if all it takes is a software patch, then that means there already a fluid level switch in the reservoir. Unless they are doing some magic computation that measures the brake fluid pressure and the brake pedal position that's able to detect air bubbles in the line. Modern ABS controllers are already doing a full physics simulation of the hydraulic brake circuits, so it's possible.

Do people actually think that? I always thought they were just cosplaying.
