I believe he claimed that they did have all of the sensors they need with hardware v2, and they had no need for LIDAR. We'll see if that's true. One thing that stood out to me is that he said they only need radar in front becaus

There's a corner two blocks from my apartment in SF where I regularly see women hustling. I've even been approached on the sidewalk in Union Square, which is an area heavily trafficked by tourists.

But everything is not currently fine on price or performance. Most places don't even really have a duopoly. It's a single cable TV/internet operator and a single DSL operator, the DSL is way slower than the cable and both a

There's a lot of interest in rust because the language gives you the performance of C without the risk of memory bugs, and the tooling is pretty good. This project really takes advantage of those qualities in order to run massive simul

I Reddit a lot, with the old design + RES, and the Reddit is Fun app. I have not liked the new design because it's harder to scroll past stories I don't care about, and I can't view full text posts without going to the commen

Rock climbing is like solving a puzzle with your body. You can't just go straight up. You have to analyze all of the differently shaped holds and walls and figure out how to position your body to maximize your grip while minimizing the

Except lithium ion batteries are very recyclable, and rare earth elements aren't in limited supply, they're just usually very sparsely distributed.

Or people to stop believing that you have to work to live. Imagine how the world would have to change if everyone decided to stop doing crappy jobs because they don't like them.

That requires all of the apps to be built with the same exact version of the library.

Time and money are different things. Many people are not paid on a time-basis. Taking 20% of the earnings of a minimum wage laborer working 80 hours a week is much more burdensome than 20% of the wages of a stock broker who makes $1M/y

A flat tax rate is a bad idea, because as your wealth increases the incremental utility of money decreases. This is why we have a marginal tax rate system in the US. The highest rates only apply to the portions of income greater than $500k.

I think you missed something in the parent comment. Bazel can skip compiling an output file if the hashes for its source code files + BUILD files have an artifact in the remote (or local) cache. This requires reproducible builds or else you

Git hashes can be inserted in reproducible builds, they are deterministic.

I have the 2018 XPS 13, running Ubuntu. It worked pretty well on 16.04, until I upgraded past kernel 4.15. Now there's a bug where it either won't stay asleep, or when it wakes up the WiFi and Bluetooth devices are non-functional

This is why I like the idea of building a spinning station in orbit and wrangling asteroids into orbit for mining and refining. Simulating a full Earth gravity in space would allow using existing industrial processes and allow humans to wor

Not true, they also come with hardware enablement updates (new kernel, graphics drivers, X and Wayland).

This has been debunked. 10 rivers in China account for 90% of plastic carried to the ocean by rivers . "...all rivers contribute between 5 and 34.4% of the total annual land-based input of plastics into the ocean, and 88-95% of this c

We're in a kind of interesting economic situation when it comes to consumer compute and bandwidth resources. There's no "billing" for compute time on the server side nor on the client side. Bandwidth costs are also negli

IPv6 will help by eliminating NAT (and thus port forwarding problems). IPFS might help with redundancy. But yeah the cost and complexity are major problems. I think the biggest problem is making open standards that can evolve quickly. All t

Building in cities is difficult partly due to the way zoning laws work in the US. Established zones also have residents that have political clout, which encourages sprawling into uncontroversial areas. https://devonzuegel.com&#x2

Only if they are able to remember which house has a bench with a liftable top. It might not be effective against a thief who lives nearby, but it would keep the package out of plain sight for the ones cruising around in cars.

Also I totally forgot about water usage as well. Most of the time it is much cheaper to use water than it should be, and cattle consume huge amounts of it.
