Serious question- what is Tesla's technological advantage with batteries? I always hear people say that Tesla batteries are above and beyond all competitors, and then I read articles like this which make me doubt that claim: https:&#

I would be more sympathetic to your argument if Tesla marketed Autopilot as a driver assistance feature. But that's not at all how they market it. When you go to Tesla's Autopilot page, you immediately see a video of a Tesla dri

I got a similar vibe- I think the article is fiction, or at least primarily fiction. Everything fits too perfectly into the narrative the anonymous author is telling. And the ending is just too cute to be believed.

Thanks for the links. Their "Vehicle Safety Report" is literally 3 sentences! I expected such a report to have much more detailed information in it.

Tesla made some very big claims in their recent autonomy day event- basically, they claimed that they are years ahead of competitors, while operating on "hard" mode (no lidar). And yet, a number of participants in the short auton

A Twitter user who rooted his Tesla claims that autopilot disengagement reports are very small (< 1 KB) and do not contain any actual sensor data, just things like GPS coordinates, speed, heading, etc.: https://twitter.com&#x

This wasn't reported much, but Tesla also expanded their ABL (Asset Based Lending) credit agreement by $500M in March 2019: https://ir.tesla.com/node/19561/html Without that, they would have $500M less cash o

I disagree with your "text is superior" stance. You assume that the point of a phone call is to enhance "shared knowledge building", but that's often not the case. A phone call is meant to communicate something di

I think the worst part of it (as the article mentions) is that it feels like you are doing something productive when you're using Slack, but the majority of time you're actually not. You're generating conversations, notifica

by rjdagost 8y ago
For myself, Slack is such a time waster that I'm at the point where I only check on it periodically. I tell coworkers that if there's an emergency that needs to be tended to right away, just text, call, or talk to me in person.

There are many scenarios I could posit, but I'll pick one. Let's say your pre-revenue start-up needs a product for sale within 4 months, because that's your company's runway. There's a lot of work to do and limite

Having had a front-row seat to the data, what's your take? Do you think Tesla's Autosteer helps, hinders, or keep accident rates unchanged?

For myself, I was surprised by how low-level Tensorflow was. I found that basic operations (things like saving and reloading a trained model) were much more difficult than in Keras, scikit-learn, or other machine learning libraries. Using

We could go back and forth on this all day, but I don't think you would say these vehicles are good drivers if you have actually driven amongst them. I recommend that you follow one of these Waymo vehicles if you're ever in Chand

I hear what you're saying about the letter of the law and all, but the fact of the matter is that at big intersections people don't drive that way in any country that I've been to. Waymo cars have an annoying tendency to jus

My brother lives in the neighborhood where this public beta testing is occurring. Folks, let me tell you from first-hand experience- these cars are terrible drivers. They are extremely hesitant, and because of this they cause traffic back

SpaceX executives have stated several times that their company is profitable. But, when SpaceX was trying to do a $750M debt raise just last month, their internal financials were divulged: https://www.bloomberg.com/news&#x

Some argue that allowing residents of high tax states to deduct more from their federal taxes is in effect a subsidy to high tax states. Why should someone who lives in Washington or Texas (no state income tax) have to pay more in federal

You are absolutely correct. I do long distance bicycle rides through rural areas. When you've been riding for hours without signs of civilization (other than the road itself), a Dollar General that pops up in the middle of nowhere is

A lot of longs loaded up on Tesla shares because they believed his "funding secured" tweet. Are you OK with them losing their shirts, too? Because many of them did.

Often I will do some prototyping with scikit-learn and then write my own implementation in numpy / scipy for something that goes into production. But I have used scikit-learn in production as well without issue. I have used MATLAB a

scikit-learn does have its share of inconsistencies and strange omissions, but I have found it to be much, much easier to use than the alternatives.

I get why Euler angles are not ideal (gimbal lock). But what are the advantages of quaternions over rotation matrices?

What data does Tesla actually collect? They are very vague on this point, but people act as if a Tesla driving around is collecting the same quality of data as a Google self driving car. On this point I am highly skeptical.

It is not odd that the tides have turned against Musk. What is odd is that it took this long for the tides to turn against him. That a company is still around after incinerating cash so rapidly and consistently for ~16 years is an incred

I used to work in the automotive industry. It is common to push suppliers for price reductions on existing and future agreements. But I have never heard of partial refunds on past sales. This is not a smart game of chicken to play. If y
