Attack the argument, not the person. No racism/sexism/bigotry. Good faith argumentation only. This includes accusing another user of being a bot or paid actor. Trolling is uncivil and is grounds for removal and/or a community ban. Do not respond to rule-breaking content; report it and move on.
2. All posts should contain a source (url) that is as reliable and unbiased as possible and must only contain one link.
Obvious right or left wing sources will be removed at the mods discretion. Supporting links can be added in comments or posted seperately but not to the post body.
3. No bots, spam or self-promotion.
Only approved bots, which follow the guidelines for bots set by the instance, are allowed.
4. Post titles should be the same as the article used as source.
Posts which titles don’t match the source won’t be removed, but the autoMod will notify you, and if your title misrepresents the original article, the post will be deleted. If the site changed their headline, the bot might still contact you, just ignore it, we won’t delete your post.
5. Only recent news is allowed.
Posts must be news from the most recent 30 days.
6. All posts must be news articles.
No opinion pieces, Listicles, editorials or celebrity gossip is allowed. All posts will be judged on a case-by-case basis.
7. No duplicate posts.
If a source you used was already posted by someone else, the autoMod will leave a message. Please remove your post if the autoMod is correct. If the post that matches your post is very old, we refer you to rule 5.
8. Misinformation is prohibited.
Misinformation / propaganda is strictly prohibited. Any comment or post containing or linking to misinformation will be removed. If you feel that your post has been removed in error, credible sources must be provided.
9. No link shorteners.
The auto mod will contact you if a link shortener is detected, please delete your post if they are right.
10. Don't copy entire article in your post body
For copyright reasons, you are not allowed to copy an entire article into your post body. This is an instance wide rule, that is strictly enforced in this community.

I have such high hopes for the Slate.
I don’t want any fucking software. At all. I just want a regular-sized electric truck.
Todays regular or 1980's regular size?
Have you seen pics of it? It looks about the size of an old Toyota pickup.
Chevy Luv sized from the looks of the pictures.
Brushless DC motors are the most efficient way to make an EV. The controllers on those require software. Battery charge balancing also needs software; it's dangerous to just feed voltage to lipos.
You can't have anything like a modern EV without software of some kind. You can make a glorified golf cart, but its range/efficiency would be shit.
You could run basic brushless motor and BMC firmware on a 99 cent 8 bit Atmel ATMega 328. That code requires almost nothing to run. It's all the extra shit baked in that needs all sorts of processing power.
I also want a basic barebones infotainment-delete vehicle that just has power windows,locks,AC, cruise, and 4x4/awd. I don't want some proprietary gps system or a dashboard where I have to hit 3 menu buttons on a screen I have to look at, just to change a setting (how my wife's car operates and it's a complete shit user experience).
Going a step further, one could, with a bit of difficulty, build the logic out of discrete parts (or packaged ICs) and have it simply work as an electromechanical device. Like things in cars used to.
Complexity and propriety make for good income when it comes to fixing your broken fancy stuff; there's a good incentive to keep it that way. I praise the companies that make long lasting, well designed, and serviceable goods.
So what you're saying is, there's software.
Technically it's not software, it's firmware, because it's a microcontroller that runs code directly.
To my point, you don't need all the fancy bullshit that's baked into the car, the actual control systems require very little compute power.
Firmware is just software. I've done this stuff, it's all just software.
When it comes to writing code, perhaps. But specifically, I disagree on principle. There's a big difference between Firmware embedded directly into ROM that requires nothing beyond the MCU to run, versus Software that requires both a host environment to compute it, host hardware to store and manipulate it, and IO peripherals to make it useful. Totally opposite ends of the OSI model.
All that comes down to abstraction. Lots of stuff has been implemented in bare metal without making the distinction. Every DOS program was almost entirely bare metal except for loading it into memory and some disk I/O.
Firmware is just a subtype of software.
ROM doesn't really exist anymore except on some legacy stuff. Certainly not on the ATmega series you were talking about. At most, these things have fuses that can be intentionally burned out after flashing so they can't be overwitten later.
Huh, That's weird, the last time I checked, the 328P had 1024b of EEPROM.
Did you really not know what they meant?
Yes, they don't want any fucking software, at all. That's a very absolute statement.
That response was part of a thread of conversation. That original post talked about shortcomings of the computer controlled displays and infotainment system. The prior post adds context the indicates the post you're responding to was not making an absolute statement.
The ev part was great. It was all the other software that sucked. Most of that is shared among other fords.
That’s going to be the question: is it regular size or tiny? As a larger guy not interested in a truck, this is a great idea and I was tempted to put down a deposit. However there are vehicles I can’t comfortably use and this could be one of them. Also, I like the customization bits but those didn’t have pricing so could make the vehicle much more expensive
