Yes - I totally agree. I was really just congratulating myself on being able to follow it. I find it interesting that this was easier for me to follow than the original maths papers on lambda calculus, but I suppose that's just a matte

I feel like I must have progressed as a programmer somewhat. Even though I doubt I could write an article like this from scratch, I can now at least follow it, and there are no more "wtf did he do there?" leaps of logic. Post this

Pretty sure the OP meant headphones in general, not Beats specifically.

It's not an RRT[1] if it doesn't employ a Voronoi bias to sample within the largest Voronoi cell. Since the first paragraph describing the "RRT" implementation admits it didn't explore properly, it really wasn'

I absolutely agree - and this is precisely the option I elected to implement for the autonomous vehicles I worked on. Interestingly enough, I did all this autonomous vehicles work during my PhD, and my actual thesis ended up being about how

In a manner of speaking what you say is true, because we've classed all forms of crash as being equally bad (infinitely so). And our vehicles were empty of humans, so we deemed their destruction as insignificant compared to harming any

The second option (turning off all guidance) is effectively what I did (see https://news.ycombinator.com/item?id=7708105 ). Upon recognising that we had no controlled trajectories that were viable, we just tried to reduce ki

Yes, you're totally right and I've edited my phrasing. I was trying to cover the issue of not allowing any more petrol to be turned into kinetic energy, and muddled my own brain... :-)

I have personally written algorithms to select paths for 800kg autonomous vehicles operating around humans and livestock, and that minimise some cost function. My cost functions always treated crashes as (effectively) infinite cost. In the

In terms of "sportsman who is so far ahead of his peers that it's almost impossible to explain how", then yes, I think Bradman fits the bill!

I used to run the world's biggest juggling video repository (JuggleThis.net, now defunct) which itself was definitely responsible for a lot of the irritation Gatto found with the new generation of camera-happy juggling kids. Certainly

This reminds me of one Rio Tinto executive's dismissal of their $70M dollar purchase of a set of autonomous Komatsu haul trucks as "a very expensive reconfigurable conveyor belt".

Generally LIDAR "works" reasonably in light rain because the rain drops scatter most of the emitted beams, and you get no returns. Occasionally you'll hit a raindrop straight on and get a reflection back to the receiver, but

Or they invest in a mechanical turk "supervisory remote driver" system.

Well there are "Flash Lidar" sensors, that are effectively instantaneous depth cameras firing a lidar beam for every pixel - but a) they're hugely expensive, and b) they don't seem to have taken off (possibly because aca

No, snow scatters the emitted light and scarcely any is returned at all. A wall covered in ice looks like an air gap. (I know this because my very expensive 800kg autonomous vehicle almost drove into a lake under my software control due to

In pathological scenarios where the edge weights change near the goal, rather than near the start of the search, D-star and all its backwards-incremental-graph-search variants can be slower than regular A-star. I would only recommend the us

It doesn't provide the "Suggest Edits" feature for blog posts, only answers to questions. Until I discovered Quora, I was working on http://wikiblog.jugglethis.net/ which was my solution to this problem.

I made something like #1 a few years ago, but it never took off and I eventually grew bored of it. It's on Google App Engine and open source if anyone is interested to continue with it. http://wikiblog.jugglethis.net

The article links to a Schneier article which suggests using random keyboard mashing as an answer to "Security" questions. This is all well and good until you need to use the Australian Government Centrelink application, in which

The article states that it's not "technically" a meteorite until it hits the earth. So what would it be called had the skydiver managed to catch it?

This is a surprisingly well-engineered and effective display, given the price point once injection molds are made. I've had the opportunity to try it out in person, and would love to tinker with one myself. If you're at all curiou

Argh! About 90% of the people mentioned in this article are Doctors, not Misters. And approximately zero of them are introduced before their names are first mentioned. Likewise acronyms. Who edited this crap?

Whoever those people are, I don't want them in my "friends" list.

I do want to build autonomous vehicles, and I have the Ph.D. where I did just that to validate my ability - but, and this is a big but, I don't want to do it in Silicon Valley. There are plenty of excellent American robotics engineers

Given the number of "we deliver X" businesses trying to find a way to maintain a profit margin on deliveries, there's probably a reasonable business in a "travelling salesman as a service" product...

I'm a little concerned that the RSPCA has warrantless access to my browsing history already. Aren't they a volunteer organisation that promotes animal welfare?

From their launch conf pitch, they did an experiment in a stadium with an attendance figure of 20000 and found 71% of attendees had a phone with wifi enabled. No idea if that audience is representative, but it seems plausible to me.

Seems legit to me - a bunch of robots on the elevator that are each responsible for perhaps ten kilometres of travel, and they pass the parcel to the next one in line then move back down. You could launch way more things in pseudo-parallel

Couldn't the tether just have a friendly robot in charge of what I'll politely refer to as "catch and release"?
