The Maxwell Technologies battery technology is allegedly 10x cheaper to manufacture due to no oven or liquids and as a result, and also lighter. Elon says the "holy grail" of batteries is being able to develop an automotive grade

A lot of the tech in the Tesla vehicles is truly innovative. Look at the seemingly simple cooling bottle they use, which is the best in the entire automotive industry (and patented by them): https://jalopnik.com/the-tesla-mo

I shared this in our #git internal slack channel and immediately had a dozen people bemoaning it not supporting our GHE. Thanks!

Too bad this doesn't work with Github Enterprise :(

There was an internal SpaceX presentation video which was leaked to r/SpaceX that stated their launch cost to be $30 million per launch. The video was taken down later that day, but that's the currently best known number for how m

Given that space is tinkering with Starship and Superheavy, they will be able to bring their costs massively down. It will just take them a few more years most likely. In reality, the cheaper access to space opens up so many more opportunit

That's fair, but I'm sort of afraid / amazed by autopilot. I have been through FAA flight school and you learn to develop an instrument panel "scan" in instrument rated flight. I find myself having developed a &quot

The inverse is also true. There are plenty of videos of autopilot preventing wrecks that the human drivers said they likely would have wrecked on themselves. I happen to be one of those drivers when someone pulled onto the highway from a fi

"the biggest bugs in btrfs were when you came close to filling up the filesystem" :) I used to read every email on btrfs-devel for a year or so.

xfs + dm-snapshot / lvm snapshots. Very fast and very reliable.

Historically, the biggest bugs in btrfs were when you came close to filling up the filesystem. For the longest time, you'd get -ENOSPC (no space left) even when you had many Gb of space left due to really bad metadata and block level s

Wouldn't you sort of expect the military to implement zero trust networking where possible?

Your question is rhetorical here, right?

American Fuzzy Lop? It's a fuzzer. I've never heard of a fuzzer described as a genetic algorithm that tests code paths, but that is technically correct. A fuzzer is not going to replace unit tests or good SDLC, which often involve

Do you write unit tests? Do you care about coverage of your tests? Serious question.

That hard part would be preventing HN from doing people's job / homework here.

We should let the market decide. This is exactly how it does it.

The quality on the 3 is fine. I've heard so many panel gap anecdotes and "fit and finish" problem that I was a bit excessive in my inspection of my Model 3 before I took delivery (November 2018). It was fine. There are no qua

You're seeing it wrong. We figured the Tesla would be useful for some things but not for long trips. Since there are gas stations literally everywhere we were worried we'd not be able to take the Tesla on long drives. It turns out

You must not have heard from an actual Tesla owner. In the most recent update (last week) virtually everything can be done by voice. You can literally say, “my butt is cold” and it will turn on the seat heater. You can say, “turn up the hea
