Meta: Posted by a 6 day old account that has made 18 submissions, only 1 of which is technology related, the other 17 are all political/social/economic propaganda stories.

I've been seeing this pattern a lot recently; 1-2 week old accounts that join and just immediately start submitting 2-3 political stories every single day, and they also never write a single comment.

I assume that thats very little of the spam that actually gets posted as that is just what gets through @dang 's net/automatic moderation.

It used to be an interview question I'd ask of electrical and electronic engineers:

> You work for an EV company who has just invented a car which can charge as fast as a regular car fills with gasoline (2 liters per second). Your job is to design the cable. Where are you going to start?

A good candidate will quickly realise the task is near impossible. One has to either accept cable which is unreasonably heavy, take huge energy losses, or have a 100kilovolt 10's of megawatts scale buck convertor ($1M of electronics) in every vehicle.

Why do you need a cable? We are thinking in the realm of pumping fuel. Instead you could use a rail under the car or many other methods.

How many amps, how many volts, what will the rail be made from, how big will the pickup 'shoes' be?

You can also "cheat" a bit by splitting the battery like some cellphones do now. Instead of charging one giant battery you are charging two smaller ones at the same time.

You're all hired.

What is the top reasonable voltage? Believe chargers are up to 800 now.

Subtle :)

Umm I think Tesla is slumping for a very different reason than what’s going on with a Chinese rival

We are supposed to believe 'rivals'? When deep seek came out, the press (and many in the tech community) believed the hype with no proof. When it finally came out that the initial claims were false, everybody just moved on.

What actually happened was that Nvidia stock crashed so that the Chinese firm that built Deep Seek (interestingly enough, an HFT firm) could buy the the dip and make millions.

Most likely what's happening here.

It's not just Chinese EVs affecting the stock though, the CEO of Tesla has likely destroyed a huge amount of value by simply being a repugnant person loud and publicly, and the culture of Tesla customer service and the fact that people share negative stories online has destroyed an equal amount of value.

I will never trust a CEO who posts on social media and takes drugs. Give me boring Ford and Chrysler.

I’m baffled that the Nazi salutes failed to make the list of your “never would I ever”

We all tested Deepseek and it performs better. What more proof do you want?

At some point you need to accept that others can be better than you. Once you do you can learn from them and get better as well.

Claims were overhyped by the media, but were the actual deepseek claims false though? Huggingface and universities have replicated the deepseek chain of thought training on top of llama for very cheap, and the openai pricing for o3-mini shows how cheap that model is vs the original o1.

Not to say that I buy this EV hype, which is suspiciously timed with teslas weakening position.

I mean has Tesla actually delivered on anything they've promised? FSD has been promised for years

BYD's credibility is much higher than Tesla's. Even disregarding recent developments.

I am aware of DeepSeek's ownership but what is the source on their use of it solely to buy nvda shares?
