> Here's my worst-case scenario: you have 8 concurrent threads (a current reality on POWER8), and let's say all of them are engaged in fetching large amounts of data from different servers - let's say disk and TCP I/O are both servers.

Speculating: if you were passing all the data in messages, terribly. But that's not how you'd handle it. You'd use messages as a control channel instead, similar to DMA or SIMD instructions. E.g. if you're downloading a file to disk, the browser asks to write a file, the filesystem server does its thing to arrange to have a file and gets a DMA channel from the disk driver server. The TCP layer likewise does its thing and gets a DMA channel from the network card driver, and either the browser or a dedicated bulk-transfer server connects them up. The bulk data should never even hit the processor, yet alone the message-passing routines.

Do. Also look at QNX which is the big commercial successful microkernel.

> Humans aren't really good at driving either,

I'm not sure where did that come from. One fatality per 200 million miles not good? Seriously, there are millions of people travelling every day. And true, there are accidents, but I think this "Humans aren't really good at driving" mantra is not really serious (but frequently repeated recently by PR of some companies).

Attentive humans are extremely good at driving, distracted humans are much worse, but perhaps the technology should focus first on the much easier task of making sure the driver attends. That would probably safe many lives, before we can have a real autonomous car.
>> Safety - they'll be safer. Period.

>>* It's a natural extension for cos like uber - how else can they bring costs down enough?

> I don't know or care.

The point is that they're dumping money into the tech for their own purposes, regardless of effectiveness as a consumer product

>> It meshes well with other aspects of tech reducing friction - deliveries will be cheaper (think dinner, groceries, taskrabbit)

> Well, why do you think the providers will reduce the cost? They can always add to their profit, instead of making the service cheaper.

I sure hope they do; I'd doubt any of those comapanies make any profit as is. And again, they'll be willing to spend lots of money on the cars, making them a viable product without the consumer market.

Until ~2010ish, Opera was per-se pretty much competitive (after that, the other vendors were implementing new specs quicker), but there were some notable differences, especially around places where specs allowed multiple behaviours and every vendor except for Opera had converged on one behaviour a decade earlier (rounding of CSS values comes to mind here, but was far from the only case), and that caused more and more problems and web-developer pain as the web became increasingly complex.

What truly impresses me is how people can find a purpose big enough to continue studying for years and, more importantly, with the right attitude.

Without a purpose it is hard to retain vocabulary for good. In fact, I had forgotten the Chinese character for "Thank you" even though I studied the most basic characters daily for about 6 months some years ago.

Learning English, otoh, has been rather easy as my interest in things such as programming pretty much require it. But then again there is French. Even though I wanted to be able to use it outside school I was never able to have a real conversation in this language. There just wasn't anything French I really connected with. Even their TV program is boring ;)
This is offset in part by reducing or eliminating transportation costs and intermediation.

I was reading an interesting article about the farmer's market in my country, production is actually not the largest cost, it's less than half of the actual sale price.

See for example:

(spanish) the article I was reading: http://www.cnfr.org.uy/uploads/files/Manual_de_comercializac...
I'll take a quick stab. First off it's not a software computer system. Their are so many different elements in play. Your robot needs to know about soil science, agronomy, pests, weather predictions, stock markets, machinery, the list goes on.

Farmers have to wear many different hats. You are a seed scientists for part of year when you figure out which seed you should plant for next season. This choice involves many other factors (weather predictions, personal yield goals etc). During planting season you have to make human decisions of when to plant/not plant. Training a robot to make this decision would be very complicated and most likely involve many 'failed' attempts that cost tons of $$$.

Lets say you did get the robot to choose a good seed, then you hired a fleet of robots to plant corn on 5000 acres and they successfully chose the correct times, right plant depths, row spacing, seeding rates, and managed to get the crop fully planted without any hiccups.. At this point you would then need to be scouting the fields, most likely putting down some N after planting. Robots have to decide which fertilizer goes where, how much to put on, is each field the same or does field X get higher N on one side but less N on other??

THEN lets assume all your crops grow fine, weather behaves (never does)and your robot fleet has scouted all fields. Then the robots must go out and harvest the grain. The combine picks up grain which then gets dumped into a semi on side of the road. Again maybe there is a 'harvest semi for Uber' kind of service where automated semis drive around between combine and elevator at will.

Another decision to be made is selling the grain or storing it...

In short, there are way too many decisions and farmers (i'm thinking midwest corn/beans guys) have to make across many disciplines. These guys have an intrinsic knowledge about their land that has been accumulating for 10s or 100s of years!

The biggest thing to remember is that a manager is a servant of the team. Never the other way around. You enable them to do work. Which means handling information, communicating, helping them communicate, talking to management, protecting them from unreasonableness, setting clear goals, going to pick up the dang pizza yourself so the work doesn't stop, making sure there are long stretches of time to do work,etc. You do more grunt work than anybody and in return leadership happens.

There might be an easy solution, they could provide more flexibility on using safety features, kind of like Perl did it, i.e. let anyone disable/enable a particular strict feature for a particular scope, for example "no borrowcheck;" or something. This will make it easier and more flexible for everyone, newcomers will be able to gradually learn more about the language and still get things done in the meantime, and power users will understand where satisfying the compiler is not worth it and will be more productive as a result without worrying about overly broad unsafe.

You see yields like that in the US west of the 100th meridian. It's a stark divide. On the east side, farmers put seeds in the ground, rain does the rest, and you get amazing yields. West is substantially more dry. There, you see irigation and dry land techniques.

Visualizing convolutional neural nets with cats and keras
It's not very surprising to me. Paraphrasing, "once I got past the initial hurdle of the borrow checker, programming in Rust became much easier," is frequently uttered in the Rust community.

I'm not trying to make a very nuanced claim here. All I'm saying is that there's clearly a lot of people who struggle while learning Rust, but that this is very different than paying an eternal development cost similar to that struggle. We should be careful not to conflate them.

(I did not meant to get into a broader philosophical discussion about using a type system. That's a different conversation IMO, and I disagree with your analysis because you only focus on the upfront cost while neglecting the maintenance costs in the absence of such proofs.)
Basic geometry. A pothole of greater then a certain depth, at a known angle from sensor will produce a different distance profile (namely - rather then an expected arc, you'd see a sudden increase in distance, corresponding to a non-planar surface). Depth is inferred from the deviation from the plane of the road-surface around it.

This is not actually a particularly interesting edge case.

The water-case is more interesting, but I would counter by posing the question of how a human would know whether a water-filled pot hole is safe to navigate? A clear water pothole would not impinge the LIDAR, a murky water one might and could fool LIDAR I suppose (I can not find any solid info on this interface).

Of course car RADAR and a visual camera are likely to also be fitted - both of which could identify a water-filled pothole which LIDAR might struggle with (RADAR can penetrate water and find the unknown backscatter, a camera can simply see the murky-water pothole and choose to navigate around it or stop - in both cases a human can't make a better informed decision).
I think this actually IS the case, but it isn't polliticaly correct. From my observation most people are not "in constant search of freedom to do anything they want" and just don't bother actively searching for being free from 9-5. There are even people with talent for slavery. There are people on every end of any spectrum you might choose, just look at BDSM scene as an exmple. According to "normal people": "Who in their right mind would choose to be a sex slave and get beaten?". Yet such people exist, I've met them and understand them.

And that is great, my organization actually respects this and doesn't force me to go to any annual things. To each their own, but shared meals and drinks in the evening is for me too much. I work 8 hours for you, after I want to see my family or friends, not my co-workers. Or do sports, or whatever else. The problem with these retreats is 8+hours work and then off time with co-workers. I don't care about that. AT ALL.
> That the world is not solid but made up of tiny particles

I'm not sure that's how most people understand it. "Tiny particles" still maintains the notion for most of us of a physical / materialist world when things truly exist, with some kind of an inner essence or structure or core, which we would associate to these "particles".

Se we think that a tree, or a car, is a bunch of those particles. And that we too are a bunch of particles. It doesn't shake the notion of physical existence so it has no profound impact on the way we see ourselves and the world and the way we behave.

It's very hard to let go of this view though. A very healthy and middle step that I wish was taught everywhere is to start looking at the world as an interdependent system, including us, and understand nothing truly exists in isolation.
What do you think a human would do differently in this scenario? If a normal person is driving home late and sees even just one person standing in the road, they'll probably slow down for them before even thinking about it, just like the car. I think if this were such an effective way to mug people, it would already be a major problem.

And again, you're talking about a car that's surrounded by cameras by design. It would be easy to include a button that immediately starts streaming all camera info to cloud storage (or indeed, just do so by default if mugging were such a huge problem).
I've spent 3 years as an associate in a VC firm. I graduated in computer engineering. And I was invited by the CEO of a rapid growing company (www.inlocomedia.com) to be a product manager of their new Data products.

I think the tech background is important, but the most important thing is to be able to talk to all stakeholders. As a product manager you will have many interfaces with marketing, management, operations, biz dev, and your team (the engineers). You have to be able to communicate well with everybody and provide context and value.

>When there's snow on the road hiding lane markings, someone will come and clean it out.

In New England, snow can completely cover the road surface for days or even weeks at a time, and ever-changing piles of snow cover the curbs and parts of the lanes. Humans just choose a path without regard to where the lanes are in the summer. On some roads this turns a four lane road into a two lane road with a lane-width snow pile between the lanes. In a few spots it turns a two lane road into a one lane, with drivers from different directions taking turns.
IMO a lot of companies are trying to put more sensors on things which seems kinda dumb to me. Ok you can put 100 soil moisture sensors in my one field for 'precision ag' but what happens when i drive a big ass tractor over the field and smash the sensors?

There is a push for being more 'data-driven' and many farmers are adopting these technologies now. Some companies are more of a book-keeping type thing where you can put in your activites, they will show you some satellite imagery etc. There is also a big push for sustainability now. One of these companies is http://www.agrible.com/
Good. But will the panel prices drop as a result?
I think it's more a matter of timeframes. Escalators have been around since the end of the 19th century, and it has taken about a century for humans to develop 'laws of the road.' But as the article shows, facility owners have not yet adapted to the change in human behavior and facility owners are who buys escalators. And few bureaucrats, whether in San Fransisco or China, are going to go out on a limb and demand an unproven asymmetric escalator design.

So for manufacturers there's no demand and there will not be for several decades at best...escalators are long life cycle equipment and an asymmetric escalator doesn't pay for itself through energy savings and the increased maintenance costs of asymmetric ridership aren't high enough to justify a swapout...even if a bureaucrat could get the budget to cover initial cost, which most can't.
Out of curiosity, did anyone here regularly use the 3D features of a television? I've seen them used to good effect for various demonstrations and interactive displays and such, but don't know any regular end-consumers who used the features regularly (despite knowing people who owned the televisions).

I don't typically respond to comments like this anywhere, but I think this kind of view is dangerous to have. And it's one the Rust community at large seems to try to shy away from.

This kind of attitude towards people trying out a new language is damaging to the person trying the new language and to people who are part of that languages community. The former because it will give them the notion that the community is hostile towards them and newcomers in general and the latter because it can enforce a dogmatic view of the language ("you do it our way or no way!" kind of feel).

A language's ability to have people pick it up easily is important. In Rust's case there is definitely always going to be a bit of a hump for people to get over, but the concern put forth in this article seems like a legitimate one, but one the Rust community seems to be aware of. Acknowledging and helping people with these problems (while searching for a way to potentially avoid such a situation for the next newcomer) is important and it's critical that you not simply dismiss someone's opinion because they don't know or understand "the right way to do it" yet.
With the extra depth dimension they should've seen that coming from a mile away....

you'd have to re-teach most than half to three-quarters of the world on how to drive sanely, good luck with that).

This is already happening in the wealthier parts of the world.

I don't think current self-driving cars will work very well in India. But I think they'd work just fine in the rich parts of Pune, to name one area I know well. That's because driving norms in this region are already becoming quite sane. From what I've seen the same is true in the wealthier parts of Mumbai. Lane discipline isn't quite as good as in the US, but I'm perfectly comfortable driving a two wheeler on these roads.

(I'd be a lot more scared driving in Delhi.)

I question whether "sane" driving is actually cultural. Is it possible that "sane driving" is actually just the natural human reaction to good roads and homogeneous vehicles capable of driving at similar speeds (as opposed to a mix of cars, auto rickshaws, pedal rickshaws, 3 wheeled mini trucks, etc)?

"Cartapping has been happening for years — in a 2014 warrant, New York police officials were able to pull SiriusXM Satellite location information. The police asked SiriusXM to install a tracker in the vehicle’s car, which was up for an alleged illegal gambling enterprise, for a period of 10 days. But how exactly could they tap into the vehicle? Well, it was quite easy. SiriusXM reported that they turned on the stolen vehicle recovery feature, which was a subset of its Connected Vehicle Services."

IANAL but using a 'stolen vehicle recovery feature' for a warrant doesn't sound like something that should be legal.
