Tesla

The various software issues my Tesla M3 has are really grating at this point. I don't even have FSD, its just the regular AP software. I get: - Random decisions about turning windshield wipers on and off. Frequently it just keeps wiping a dry window, or never starts. - PHANTOM BRAKING, I've had it slam the brakes multiples times. Usually a bunch of times a week. Just for funsies. - Garbage night AP performance. Car coming in the opposing lane with its lights on? Better slam on the brakes. - Garbage bad weather performance. Just a bit of rain or snow and even TACC can't go a reasonable speed.

A whole lot of this probably comes down to the lack of radar or other sensors. And the lack of ability for them to get machine learning with only cameras to perform.

Maybe they should just send the engineering team up far north during the winter and force them to dog food their software to get around. Really it's not the individual engineers fault, it's always crap management.

Or worse, `curl xxx.com/install.sh | sudo bash`

I feel bad for some of my customers that I was shipping 3g routers until mid-2018. Looks like a couple automakers were shipping 3g equipment in 2019. I think several platforms like Tank Links are also going to have a purge when cheap 3g goes dark.

I wish there were some super cheap sparse data plans that worked out in the middle of nowhere USA. Everything out there want 10K units for get good discounts.

Whenever us-east-1 goes down you just get a really good feel for how many other companies also have pretty fragile setups. They apps I work on can deal with a few hours of downtime, so as long as I'm sure I can recover from getting totally leveled its ok. And I think it's that was for the majority of companies. Most don't want the extra effort and cost of failover.

Project Entropia?

I guess it's Entropia Universe now https://en.wikipedia.org/wiki/Entropia_Universe

Toyota just seems like it doesn’t want to admit it backed the wrong tech.

Allen Bradley has 60-70% market share in the US, is objectively terrible and has been for a long time.

Nobody wants it and the few that want it don't want to pay for it. Control engineering really isn't a branch of CS, its culturally its own thing.

Also, liability is a never ending hole with the actual PLC. If your web3 capable PLC keeps even 100-500K/Hr of production from running, then people will probably legally come after you.

I've though several time about building a PLC ecosystem taking the best of modern systems. Building up new features to allow the actual equipment manufacturers (OEMs are under-served) to rapidly spin up and manage variants. And enough ecosystem security that at least your production systems won't be ransomwared. But unless there is a wealth person or huge company out there that just absolutely wants to fund it, it's not economically viable (If you are that company or person, contact me).

The dealer networks and middlemen gatekeep the market pretty severely. You would have to essentially hand hold engineers into using it. And you are going to have a hard time selling it to risk-adverse C and D level managers.

Also good god, why are we not using certs for security on PLCs. This should have been a thing a decade ago. Only one vendor even bothers currently (Bedrock).

Codesys for the Raspberry pi is pretty capable also. Just get some cheap remote io and you can do almost anything.

That said, I still hate just about everything when it comes to PLC environments.

Copia.io is at least trying to get git going for a market that eschews version control.

I have had pretty good luck banging out a glorified calculator app for one of my products using flutter. Started from zero with flutter/dart and had a workable app in a couple weeks.

The code is pure crap since it was written while figuring out the framework. But easy enough to refactor into something more reasonable.

Now to add OTA updating over bluetooth for an ESP32 device to the app.

The Dr Zaber Sentry case is also pretty good http://zaber.com.pl/sentry/. I'm not sure they will make them again though. Mine is pretty nice, though you need to be careful about your GPU size.

This would be great, if you could buy a Pi.

I will believe it once I see them drive the same tires on West Michigan roads for 29k miles during the spring. We’ve had highways just disintegrate during the thaw here.

Man this takes me back. I got my start into being interested in programming, tech with Phrack in the late 80s while in middle school.

This would be a bit more interesting at about half the price. I could think of some fantastic applications at that point.

I had a quote that I think was around 600$/Hr. This was for someone to build and tune a PID model for an IMU we were using.

Admittedly the person had a ton of experience doing this, so they were probably well worth the money.

I like using Yubico Authenticator. I have a primary and backup Yubikey and I copy the TOTP secret to both. Its also nice that the secret is kept on the key rather than my phone.

And absorbed by black hole would pretty memorable at my memorial. Its win-win.

So small, can I make a ball peen hammer out of it and be the... lesser Thor?

How well does transaction rate increase with more precise time? Seems like it would be a sort of O(log n) progression. Though could very well just be linear as well.

“A website that helps you sell used items.”

Yea, I think that has been done.

A friend of mine has a Henney Kilowatt https://en.wikipedia.org/wiki/Henney_Kilowatt. Its neat, but that thing is a death trap. Early electric cars just had to compromise too much to even work.

I'll be cool with it when you can get the algorithm to swear a warrant, testify in court and navigate probably cause.

Fantastic, so is Apple going to notify me if someone is looking at the pics on my phone? No?

How about when Apple gets a NSL or other non-disclosable warrant and searches my phone with this tool? Still no?

Probably going to be a lot of leaked nudes by Apple soon.

I was kind of dumb and desperate at the time, I got better. These days I would just quote an amazingly unreasonable amount of money. If they said ok, well I could buy a whole lot of therapy and a house in Austin afterward.

Working for the mob is a tenuous deal. Because you probably don't know unless you are involved in illegal things. BUT like many business owners they are kind of desperate because they can't hire good talent easily.

So it could be an option (for some people, and maybe not even good), but really unless you can deal with stress and people well it won't go well. I was able to learn to deal with both pretty quickly. And I credit some of that early experience to being able to just dive into projects I know nothing about.

But it can all go sideways pretty quick. I have a feeling that is more common. Plus you don't want to be involved in an investigation.

What I want to do for a funsies project is have a bunch of Pi4 CMs plugged into a PCIE switch and a multi-host 10gige adapter.

I don't think this is possible though, I think I read somewhere that the Pi4 PCIE Root doesn't support host<->host comms.

If anyone knows different, speak up!

Hah, whenever I tell this story that is always the first thing people say.
