To simplify, radars can see how far away objects are and how fast they're moving but only dimly in what direction they are. So if you don't want your car to brake every time you pass under an overhead sign or over a metal grate you need to filter out non-moving returns to some extent. At a certain distance the cone of the radar should only be intersecting things that are actually a danger and you can start braking. But it's really good at noticing if a moving object has changed speed, like the car in front of the car in front of you braking.

On Teslas theoretically the camera is there to prevent stuff like this but vision AI isn't all there yet.

Other companies use lidar which gives pretty accurate distance and direction but not object speed. Pretty useful for avoiding obstacles but current automotive grade lidars are very expensive. Much cheaper solid state lidars seem to be imminent.
Yes, it's just focus-bracketing and that's as close as any non-Lytro cameras come to the Lytro feature as far as I'm aware

Reading a description of the Canon Dual-Pixel sensor feature https://www.canon.co.uk/cameras/eos-5d-mark-iv/dual-pixel-ra... ...it does not seem that it allows to adjust focus after the fact. It's something different again from Lytro and focus-bracketing.

As far as I can tell what it does is to capture depth information into the RAW file. I don't see how it could allow refocusing, but the examples show it allows you to selectively mask areas of the image based on distance from camera.

So you can sharpen 'just the eyes' if you slightly missed focus on them. Or selectively blur the front/back out of focus areas to get a stronger bokeh effect.

I don't get the false equivalency between your arm and your anus. The anus is neatly tucked away, and is supposed to handle fecal matter. You're not going to accidentally rub your unclean anus on some food or in your face, unless you cook differently than most people and is more flexible.

Would you put your face in your shoes for hours at a time, or rub it on the ground when you walked? Probably not, but thats no problem for the feet, because they're a different body part with different strengths and requirements.

Ungooglable problems still exist. Yesterday, for example, 30 Fanuc i industrial controllers started sending back RST tcp packets and refused to initiate new tcp connections until restarted. This behaviour occurred in a system which was stable for 2 years. Very likely an issue on one controller spread to the others by causing an error in a set of dlls from Japan. This occurred due to another set of the same DLLs connecting to 1 controller at the same time. Maybe. I have to talk to the manufacturer to get any further. Or disassemble their libraries. I have these sorts of ungoogleable problems all the time. I doubt industrial automation is the only field like this.

"Email is not a secure medium and tickets often end up in the wrong account / place."

I'm assuming this means that their ticketing system is shared across all their functions (so facilities use the same ticket system as IT and so on), if I email a ticket in with 'my account number is 123, my name is mrpatch and my phone number is 0123456789' and it ends up in the facilities queue, or a queue that is available to facilities, then they are breaching GDPR as that is PII that is visible to people who are not authorised to view that information.

By removing the ability to email in a query the data that is entered into the ticketing system can be better managed (from the example above the telephone number can be entered into the correct 'telephone' field that facilities can't see).

Perhaps a bit of a sledgehammer to crack a nut from a company that's struggling to fit their existing systems around the new legislation.

You really read my comment in the worst possible light. No one has to use facebook but so many people connect through it that there are social costs to not using it. If people want to connect with you, you can't use messenger or groups, bam, that cuts off a lot of your connection with others.

I didn't mean that using facebook is a requirement for life and I'm not sure why your first inclination is to read others' comments that way.

The downside of a laissez-faire policy towards self-driving cars could fall on anyone, but so does the upside. Again, a lot of human driven car crash victims have done nothing wrong and were victimized pretty much at random. Run over, rear-ended, T-crashed at an intersection, and could not reasonably have done anything to prevent it.
> There are comparatively few cases of succesful long term non violent integration.

I beg to differ. I live in Eastern Europe, at the crossroads of different migration waves, and I'd say we've been quite successful at integrating people over the millennia. Just look at this widely circulated genetic map of Europe (http://brilliantmaps.com/wp-content/uploads/2015/04/genetic-...), you can see that Romania (the country from where I'm from) is pretty diverse, and that happened because we're at the crossroads between "mainland" Europe, the Asian steppes, Anatolia/the Middle East etc.

And looking past genetics, I can give you countless examples of Transylvanian Saxons and Hungarians who, once they had passed the Carpathians into Wallachian and Moldavian lands, ended up by giving up their religion and language and completely assimilated (yeah, it took them a couple of generations or more, but the process was generally irreversible). The local Jews were also quite well integrated in terms of customs and everything, in fact one of the most famous Yiddish songs ("Roumania Roumania - https://www.youtube.com/watch?v=vuj-qjyUjxY") mentions Romanian foods like "mamaliga" or "pastrama" (which we stole from the Turks, but everybody from the Balkans did that) in a melancholic way, like it also belonged to them, the Jewish people who used to live here.
What causes YouTube to take down videos?
Here's a thought, what if you can get the same substance to work on the sand part of concrete?? It assumes more research and work, but the argument has a kernel of truth.. I don't sure I agree with using that to not think about the ethics of what you do, but nevertheless.
Those systems are the great ones at the moment. But almost all modern cars have those.

They're brilliant because they augment humans by leaving humans to do all the driving and staying focused on that but then taking over when the driver gets distracted and is about to hit something.

Auto-pilot does it the opposite way round. It does the driving but not as well as the human but then the human can't stay as alert as the car so isn't ready to take over.

> a very small (no?) team

"very small" doesn't mean "not proficient".

The main purpose of which was to raise enough money for hiring new team members (which, as you pointed out, is "very small").

> They seem to be trying to target practically every type of development on every platform

And results so far are great, considering that language is in alpha version: Android support (which means Java bridge, there's also a prototype for .NET one [3]), native GUI backends and declarative DSL for UI creation, low-level DSL for system programming and much more (read full description on website), fitting in ~1MB executable and, perfomance-wise, comparable with other scripting languages in speed (while having zero optimizations).

> it's unclear how much money they raised

Certanily enough to continue development with confidence. During ICO, all tokens were sould out. You can roughly calculate the cash value by yourself with ETH/USD ratio during ICO period and RED/ETH ratios for each round of exchange.

> I would have expected recent news to tie into the ICO promises

I suggest you to check recent articles on red-lang.org. ATM Red Foundation is working on establishing rules for retroactive community rewards and launching website for monthly reports. Core team progresses towards 0.6.4 release and adjusts future roadmap.

Love this, but since the book has an anti-Soviet sentiment, I don't think we could generalize this quote. In USSR you would read only what you should and you didn't really have a choice. Freedom of press was something impossible to imagine.

I cannot say that everything what we read, or choose to read today is worth reading but there is a good press, which is at times difficult to find, but you will never get to it if you don't filter.

There are a bunch of people training them from very young, with baby lead potty training.

It's certainly interesting to see the difference between countries in all baby things, e.g. UK, US, Italy, France and Japan.

- How much food you are recommended to eat when pregnant.

- What foods to avoid when pregnant.

- What foods to give to babies and when.

These all vary massively from country to country.
Ask HN: What tech stack would you choose for a serious, long-term business app
If you were about to start building a very vital brand new application for your company that needs to be maintained long term what tech stack would you choose? Put aside what devs at your company may already be comfortable with and lay out what you think is best.

When I ask tech stack I'm talking the whole dam thing, for example:

DB engine : ie MySQL, Postgres

API layer : ie Node w/joy, Java w/spring, PHP w/laravel, Elixer w/phoenix

Frontend SPA : ie React, Vue (do you use typescript or flow, webpack etc)

Caching : ie Redis, Mongo

PaaS : ie AWS, Google, Azure

Interested to hear your thoughts, and don't want any flame wars stating x is always better than y etc.

Feel free to just specify the stack but better to also back up why you think it is best in a few sentences.

Yeah, and then there's the Fujitsu Lifebook U93x. As thin and light (920g) as the MacBook (non-Pro), with comparable battery life.

But: 15W TDP CPU; RAM&SSD not soldered; USBA, USBC, HDMI, SD, SmartCard and even Ethernet(!).

Or the HP Elite X2 1012. Surface-class tablet/convertible with similar specs, but...well, 10/10 on iFixit.

Sure, those devices may have other issues (that trackpad on the Lifebook...), but tight packaging is not an excuse for unmoddability.

AI is dangerous.

If an AI becomes aware, what happens then?

I used to think that it was insanely unlikely that an AI would become aware. But after many deep thoughts on what consciousness actually seam to be. I believe it could happen at any time now just by random chance. We are closing in on the number of neurons that i believe is required.
So you'd rather 1000 other people die, rather than yourself? What kind of logical exercise is this?

2. If a human is aware, what happens then? Not much.
I haven't heard of your company or blog which is a shame since I specifically seek out material and partners in this space (see my profile, would be good to work with you).

The blog efforts at my company are admittedly poor. Without a dedicated writer the focus on resources invariably ends up directed towards new product features, fixes, customer care and on other types of marketing. Our blog has become the stereotypical 'new features' blobs that I have seen many others become. The truth is writing great content takes a huge amount of time. I do think it's worth making time to do it right if you can devote the attention and resource based on not only the significant traffic bump it can bring but also the higher quality of leads.
