(Non-antibacterial) soap just sticks to bacteria, making them more slippery, so they can be washed away. They're still alive in the drain and septic/sewer.

But soap doesn't just magically do this - it has to be foaming, as scrubbing allows the soap molecules to magnetically organize. As the hydrophobic soap molecules stick to the non-polar bacteria, they form a bubble shell that's not unlike a cell wall. To produce this foam with normal hand soap takes ~20 seconds of rotational scrubbing - a soap-Rasengan, if you will.

Bacteria are in everything, including every breath of air and gulp of water. Our immune system kills the ones which get through our small intestine's mesh system.
Paste the details here and you might find some!
Interesting, they are basically Trains running vertically switching tracks.
Is it a big surprise that you can construct adversarial examples for algorithms? Don't humans have the same class of problems with optical illusions? And those are not even adversarial, just confusing.

If we constructed truly adversarial examples for human neurology, I bet they would be equally insane.

What I expect from a Web Framework
Since when is web scraping a "malicious task"?
This actually doesn't seem that far fetched. Ex-drivers who are angry and have plenty of time on their hands out at night picking the RFID tags out of stop signs.

Another scenario is more of a slow and steady war. I'd expect that autonomous vehicles will occasionally be alone and unoccupied, which makes them a tempting and defenseless target. You wouldn't even need to do any physical damage to disable them - just a little electrical tape over their sensors, or some chocks under their tires. Soon, the autonomous trucking cos have to employ some of the ex-truck drivers to go around re-enabling their vehicles. And of course, those ex-truck drivers are in cahoots with the disbalers. That could certainly drive down their savings on labor costs.
First you have to find your market. Do not listen to anyone execpt your target audience. Stuff like "your grandma need to understand your product in 10 sec" is the most stupid advice I hear. Your market should see your value in less than 5 min.

Usualy the validation goes in 2 phases : market interest and MVP.

The first phase is about faking it until you make it. Create your landing page presenting your product (don't spend more than a day on it, you don't care about design/ branding), post in your audience's facebook group, go to their meetups, shadow them to affine your concept. The goal is to have proof of traction and the assurance the market is ready / big enough. The best metric is usualy an email list you can reuse later.

Second phase, if the first is successful is building the MVP (main viable product). It's about having the most minimalistic version of your product that you can sell. Usually it's your main feature. You MUST hack it yourself, don't spend money yet, you'll lose it. The goal is to iterate quickly to have what's called a product market fit.

Product market fit is when you can write an equation like : "when a number P people see my product, there is a conversion of C% that get me X money". Then you can launch and the rest is about scaling.

Do not spend any money (aka > 1000$) until the product market fit. Not in ads, not in freelancers, not in consultants and especially not in PR.

If you product is expensive to make or need a big chain of production, sell it before building it. If you succeed it will be you proof of product market fit

It's difficult to make a standard advice since it depends a lot of the context but key insights are :

Your market is king, refer only to them.

Make them believe 80% of the job is done when you really just have a landing page

When proof of traction hack the main feature of the product and sell it.

If you have a product market fit, congratulation you have a business / startup.
They aren't real problems because nobody smart is trying to directly hook up a road sign classifier to a steering wheel. They are trying to build complex systems where this is just one signal.

If they were trying to directly use this info, this would be the least of the serious issues. For example, there are plenty of stop signs well hidden by trees. Such a car would probably last about a mile in a non freeway setting.

A trivial model of "hey, does this make any sense appearing at this place on a map" defeats this, etc.

Of course this stuff is it is infancy and can do dumb things. But this is just isn't that big a deal.

Humans also act much worse than you imply. Look at the number of people who accelerate into crashes instead of braking, etc.
Again, doesn't mean AI should get a pass, and humans are infinitely more complex, but we shouldn't be held up as amazing at this either.

(That's actually the part that worries me. That we aren't good at it)
The first thing my mind went to was the image of muttley putting up a detour sign
Off-topic, who is the narrator? I think I've heard him on another German "corporate presentation" video, and I can hear a slight German accent...

I agree and I think the whole self driving push should be incremental anyway:

1. To begin with it is only used on motorways/highways as they are long straight roads, where the AI can take over the boring part and the driver can be left to take over if something complex happens.

2. Shared AI maps across all cars that can route everyone to/from work. As this is shared, it can balance the load and result in the least amount of traffic jams. Humans still do the driving.

3. The government sets up AI cameras that monitor city routes, and cars can tap into this information as they drive. The benefit here would be seeing the road from all angles, as well as massive computers bigger than cars doing all the number crunching. Over time more and more city routes could become approved to be fully driven by AI.

That's my approach to an incremental design at least.
looks expensive to build, purchase and maintain.

not sure there's anything "revolutionary" here.

Defending Tor – gateway to the dark web
Your solutions in detecting Chrome headless is good.

But someone who really wants to do web scraping or anything similar will use a real browser like Firefox or Chrome run it through xvfb and control it using webdriver and maybe expose it through an API. I find these to be almost undetectable.. The only way you can mitigate this is to do more interesting mitigation techniques. Liie IP detection, Captchas, etc.

edit: when I say real browser, I mean running the full browser process including extensions etc.
Those who want a more "authentic" experience would do better to use a real normal browser, and control it from outside.
> LDraw™[0] is an open standard for LEGO CAD programs that allow the user to create virtual LEGO models and scenes. You can use it to document models you have physically built, create building instructions just like LEGO, render 3D photo realistic images of your virtual models and even make animations. The possibilities are endless. Unlike real LEGO bricks where you are limited by the number of parts and colors, in LDraw nothing is impossible.

> This talk[1] will introduce the LDraw ecosystem. We will examine several tools for creating virtual LEGO models, methods of creating high-quality renderings of your models, generating instruction booklets, and take a look at the underlying format in which parts are models are represented.

> I first got into LDraw when I was in 5th grade, and it was a very good bridge between my mechanical interests in the physical world (having a very LEGO-oriented childhood) and my initial math and programming interests in the virtual world. Creating models of new LEGO parts as they came out motivated me to learn basic linear algebra while still in elementary school, and motivated me to write many simple programs to manipulate the models I was creating.

Looks to be about.... 10? times the cost of a normal elevator if I had to guess. I bet the maintenance costs are fun as well. As such, doubt you will see these except in niche buildings (things like the porsche tower, etc..)
> I'm not so sure that the benefits of removing mixing would be significant compared to slowing from having a boundary layer all the way up.

For practical purposes, the expansion of a rising thermal can be treated as adiabatic, because the mixing is not large in comparison to the volume.

One consequence of the flawed argument presented on the website is that this system will not run continuously, but only when the lapse rate is that of adiabatic expansion (dry or wet, depending on the relative humidity) - i.e. the same condition as for natural convection (and if there is condensation in the tube, that complicates the matter.) On the other hand, I suppose, if the proposal has some validity, that pumping air into the tube to raise it through an inversion might allow convection to start where it has not done so naturally, or to trigger conditional convection (where the air is buoyant only once saturated, on account of the release of latent heat as it rises further.))

I am also wondering about the Venturi effect, and the assumption that the tube will support itself against outside pressure with a 300mph wind blowing through it - though that figure comes from what appears to be a fatally flawed calculation.
As far as I can see, the design only allows 2D movement. If you wanted the lift to move toward or away from the camera, you would need either some kind of 2nd attachment point on a different side.
It seems to indicate that these machines are nowhere near as smart as they appear to be based on earlier successes. I'm starting to get worried about the possibility of another AI Winter if it turns out that reality and hype are too far apart.
The current version of the web site has 9 parts. It took me about 4 minutes to create a PDF of each part.
I would expect that some of the more basic rules win out. e.g. Don't crash into another vehicle. Do hit a pedestrian etc etc.
Google also does it all the time...

The author has certainly made his position clear, and I disagree with him too.
For me personally, currently my absolute top reason I'm dying of excitement is http://www.luna-lang.org/ Only I'm not sure if they're gonna manage to get a release out of the door; I have an impression that they understand that it's their top priority and main focus now, but I'm not sure if they really realize how far they they need to go with sacrificing features and cutting it down to absolute bare essentials, to avoid faltering into endless development hell.

That said, I have some tiny glimmer of hope that even if they go vaporware, maybe someone e.g. from around the Lambda the Ultimate community might possibly try to revive their ideas and ignite some F/OSS clone.

My understanding is that the statistics you provided do not apply to federal court. As I understand it, this Marcus going to be tried in federal court.

In any case, the United States has the second highest incarceration rate in the world.

https://en.wikipedia.org/wiki/List_of_countries_by_incarcera...

Either the US has the second highest rate of criminal activity in the world or an unusually high rate of wrongful convictions.

When Saddam Hussein won 99.96% percent of the vote in the 1995 election, we said "The fix is in" but when federal prosecutors get a 99.8% conviction rate, we say that they must be really great at their jobs!

We have a moral obligation to subject the criminal justice to serious scrutiny since so many lives are at stake - not just repeat some platitudes about how the system is stacked in favor of the defendants (not saying you were doing that but the OP certainly was).
I hate to be so cynical, but for how often the TK elevator in our building is out of service (these things have been around for 100 years and still break down more than a Fiat), I don't have the confidence necessary to step foot in this thing.

Not quite banned, but a marketing ban:

> The U.S. Food and Drug Administration today issued a final rule establishing that over-the-counter (OTC) consumer antiseptic wash products containing certain active ingredients can no longer be marketed. Companies will no longer be able to market antibacterial washes with these ingredients because manufacturers did not demonstrate that the ingredients are both safe for long-term daily use and more effective than plain soap and water in preventing illness and the spread of certain infections. Some manufacturers have already started removing these ingredients from their products.

Sure: The UK moved to a qualified right to silence some time ago.

On the flip side, UK police are far more constrained in their actions when interviewing suspects than US police are:

@ UK police are not permitted to lie to suspects in interviews

@ Interviews must be recorded from start to finish.

@ No abusive use of plea bargains: we don’t do the “take this plea bargain or risk being locked up for 60 years” thing at all.

I’m sure there are more, but those are the things that spring to mind immediately.

I’m not going to pretend that everything in the UK is sweetness and light regarding our police, but the idea that the US is a haven of civil rights compared to the UK is just completely wrong-headed.

Believe it or not, I've had reasonable luck with JB Weld. Just make sure anything that might get warm has a little bit of heat sink poking up through the stuff.

Edit: Looks like you're aiming for an actual product release. There's no substitute for potting your circuit inside its enclosure. I'd look for a silicone based solution as you're aiming for large temperature swings.
Time out of service has much more to do with who services them.

This feels like the single biggest problem in online journalism today. It seems like the root cause is really a dependence on ad impressions and page views for survival.

Note that a TK elevator doesn't mean it's actually still maintained by TK. For example in my previous building there was an Otis elevator but at some point the maintenance stickers on it became TK's, probably because they offered a cheaper maintenance contract.

TLDR: the manufacturer can't do much about the owner not maintaining their product properly.

Impressive video. The implementation looks complicated and might have reliability issues.

The thing is, kids are incredibly primed to recognise and cherish brands. I find it shocking, to be honest.

They want a Paw Patrol figurine to emerge from the play-doh, for the millionth time. Not some stupid liquid hydrogen (I view it the other way around, but I'm not the target audience).

And the pull of those silly videos is incredibly strong. We also have an excellent app with literally hundreds of educational clips from "Die Sendung mit der Maus" [1] [2]. My son likes them, and will watch them for hours on end if he gets the chance -- and so will I, because they are genuinely interesting and amusing.

Yet if given the choice, he will pick Youtube and the silly videos every time.

Wonderful. We can't have enough decent, genuinely amusing education, especially against this flood of trash.
Wait until AI puts most truckers out of a job and you suddenly have a substantial number of people in rural America feeling resentful towards fully automated freight trucks... adversarial examples are one thing, but I think the US military's experience in Iraq has taught us that a determined, intelligent, and constantly innovating human adversary is a continuing challenge.

Especially given that the cost of crashing an unmanned truck will be 100% capital and 0% human, I expect we'll start seeing some pretty serious criminal penalties passed once the tech gets there.
I think this isn't well-applicable to machine learning because if there are more data sources to be considered (like other cars' behaviour in addition to just camera images), they'll be always considered anyway. For humans, it requires considerable additional effort to do so, but for machines it's fairly cheap, so why not do it anyway?

The uncertainity part should ideally, in my understanding, be represented by confidences returned by neural networks. They don't claim "there's a crossroad ahead, and not a tollgate" but rather "85% match for crossroad, 30% match for tollgate, [...]". If those results are not distinct enough, the surrounding application should probably go into a more cautious mode and slow the car down to begin with. I suppose that's what such systems do, but maybe someone with more field knowledge can confirm/negate that.

Y’all realize this is a demo, right? Like... no one looks at “hello world” in a new language and says “man I need to make bigger applications than that, this language sucks because all it does is print to the command line!” Right? So when someone is showing off a demo of a brand new technology you do realize that this isn’t representative of how it will work in the real world, its just to show off some of the capabilities. Right? You realize that right? That you’re not actually going to have to watch a movie hunched over a table like that?

You know how I know this will be the next greatest thing? Because 90% of the top level comments here are shitting on it. Meanwhile people in the real world are playing Pokémon Go and looking at dancing hot dogs on Snapchat and actually enjoying AR on their phone right now.
If an entity doesn't see a good way to invest money, they won't borrow money to make money. This is what they mean when 'the demand for money is low'. If the government borrowed money, they would not make as much on that money as the interest payment to who they borrowed from, so they never borrow the money.

This has the overall effect of reducing money demand, reducing the premium to get that money (the interest rates continue to drop). Everyone though 0% interest was a hard line and you couldn't go lower, until negative interest rates were introduced to try and reverse this trend, which it largely hasn't.
