This is great. I've been thinking about better ways to search logs for root causes. Splunk is good if you know what you are looking for, but this is exactly what I want to see to show me unexpected things in logs.

Very cool video. Said Daimler was using 8 radars and three cameras, so sort of the inverse of the Tesla approach. The Tesla video is a bit more exciting, because it is using a car that consumers are already driving, whereas the Mercedes has

Arbitrage is a risk free transaction, so that's an oxymoron.

Tesla is probably the most vertically integrated automotive OEM. Tesla doesn't advertise via any traditional channels. Yes, they have changed people minds about EVs, but calling them a marketing company is silly, when you compare them

Panasonic just makes the cells, Tesla makes the batteries. Soon Panasonic will be making all the cells under Tesla's roof. Tesla has hired Li-Ion specialist Jeff Dahn, so at a minimum Tesla is involved is prescribing the additives to t

Electricity is basically free compared to gasoline. If you cut the price of electricity in half, it wouldn't move the needle at all on EV sales.

Yes, this is important. Tesla could blow through all of the credits in 2018. Tesla could technically benefit from the EV tax credit being cancelled after that, since its products would no longer qualify, but the other OEMs that have sat on

Nature is out there randomly mutating genes without any oversight. We need to test each plant for 100 years to make sure it didn't have any dangerous mutations.

This will change when people can make some money off charging. If you can fill up 200 miles of range for $10 in 30 minutes, then you might consider an EV even without a home charger.

What frustrates me is people saying "exponentially more" when comparing two things, like the Bolt has exponentially more range than the Leaf. I mean, you could fit an exponential curve to those data points, but also logarithmic, s

Sometimes you discharge. You may decide to not discharge ahead of a storm. If it were just backup, it would be easy, but sometimes you want to consume your storage to save money, or sell back to grid, if you have time of use pricing, or get

You are wrong. You can have multiple days. But normally you would use this to arbitrage electricity prices, especially if you don't have net metering.

Depends on the algorithms you are using. In machine learning, bigger data sets can trump better algorithms.

They should be proud of that for sure, but they just go up really high, vs. putting a payload into orbit. It's got to be an order if magnitude easier for BO. Look at how long the booster hovers and corrects it way down so gently. Space

It's interesting, but his solar PV assumptions are pretty outdated in the book. He talks about utility scale solar being 10% efficient, where as it is around 17% now. Even at 10% efficiency, he says it's feasible, but too expensiv

* US electricity is about 1/3 goal, and constantly using less coal. * Emissions out of a tailpipe happen in cities and places with people. Power Plants tend to be more remote, so the toxic gasses are emitted away from most people. * Ev

Yes, we saw people switch to more efficient transport in the US at $4/gallon. I think this is the long term ceiling, where people will switch to at least a plugin hybrid and cover 90% of their driving on electricity.

Oil is not a big part of electricity generation in most places.

I wouldn't say it's one time. There are many islands (like Hawaii) that have to import diesel to run their generators, which is very expensive. Replacing diesel generation with renewables + storage will be very attractive for a lo

They log everything whether you opt in or not. But as a cell phone user, I feel like I have opted out of all location privacy already. I'll trade my location privacy for awesome car capabilities.

Ugh, I did some VBA in Germany around 2000. So crazy that keywords were in German (and command and periods have different meanings in numbers). Totally unportable code.

Not a big enough market to make money making a better product. The tooling is super complicated and there are a limited number of potential users.

Utilities have to have excess capacity available to spin up instantly to meet demand. So you have to compare the cost and maintenance with a natural gas peaker plant. I think there is a place for Tesla's PowerPack to replace the least
