"But that's a moot point if the light isn't there in the first place."

When I said "traffic light" I meant the entire set of traffic lights of the intersection. You can't have just one lane without traffic light and all the others with. It would be highly confusing, also probably against the road laws.

The point of the traffic light taking precedence over road sign is actually part of the rules of the road. It is also required knowledge for driver exams.
Let's assume a North-South/East-West intersection. Eastbound traffic (on the Western road) sees this light.

If the Eastbound traffic can only go right, I presume the Westbound traffic can only go left. (Otherwise the Eastbound traffic would be permitted to go straight and/or left.) If that is true, then the Southbound traffic can only go straight; no turns. (It follows that there is no Northbound traffic.)

In essence, three roads converge to one. If that's so, why is this an intersection? Why not merge the roads or build a wall making incorrect crossings or turns obvious?

If Go ever gets adopted by the enterprise for full stack applications, not only devops related stuff, expect enterprise architects to come up with GoEE.
What if you really want to go straight and take the red light as a hint that it will eventually be green? 28 years of blocking the road?

According to the maintenance mentioned in the original link, the other colors are still there...

(Google streetview shows it too, but the picture dates back from when the red light was still youthful twenty years young)
It's a totally legitimate and well-formed question.

What is the point of using GraphQL if you're still implementing every query on both the server and the client? I thought GraphQL was some way of abstracting the database so that you could isolate your query logic in the client. That logic is going to require joins in a great many applications.

The big pain in the ass of writing a client/server app is keeping the queries in sync between the server and the client, from the parameters for the query itself to deserializing the result. How does GraphQL alleviate this, and if it doesn't, what are we gaining?

Thanks for any insight.

This is the normal sign, yes.
But in some towns (esp. Dresden, but now everywhere) we have simplier ones, a green arrow without light. You are allowed to turn right on red then, if traffic allows. Similar to the US.

It took me 5 minutes on my laptop at home to code out a problem that I danced around for an hour on a whiteboard being stared down at by 2 engineers in silence. Yes, I had the benefit of hindsight, but unless you've actually done a whiteboard interview yourself where your livelihood is on the line for an hour, don't act like a trivialising nonce.
By not chasing unicorns for themselves. If a founder starts a company looking only for a billion dollar valuation to retire rich and young, they only increase the inequality divide.

Rather, founder should be seeking to start companies that give opportunity to their employees to be empowered. Taking in talent from different sources (not only ivy league) and developing the skills needed for their company.

Another practical way is perhaps to create (insert buzzword here) that will open up learning of important life skills to the large swaths of under/unemployed/employable people. Grit, resilience, creativity etc.

We are in large debt repay cycle, as Ray Dalio describes it, so companies have to be bootstrapped and built with minimum risks. Empowering a generation to become life long learners is perhaps the best thing we can do as engineers. Something else to look at is environmental stability (ie safe communities, stable households etc.)

That’s just because their implementations are bad. Browsers have a “Save” context menu entry for videos by default.
Yes. The difference is that the lighted version does not require stopping (because it's only lit when there is no cross-traffic anyway), whereas the static sign does require a stop before turning.
They could still get you for plain old obstruction. The thing about laws that makes them different from code is that intent matters. Even if you follow the letter of the law you can still get into trouble if you blatantly obviously try to violate its spirit.
My name has been mentioned a couple of times, so let me give my take.

Forget the Mumps language which always ends up being criticised for all manner of reasons, as witnessed here already.

Check out the database, however - it's the hidden treasure, which sadly gets overlooked and dismissed because of conflation with the Mumps language and its poisonous baggage.

You don't need the Mumps language to access the database. My work with it these days is in JavaScript/Node.js, using it purely as a multi-model NoSQL database, accessed in-process.

Check out what can be done with it here: http://ec2.mgateway.com/ewd/ws/training.html

In particular check out the multi-model capabilities of the database and the JavaScript-orientated abstractions that are possible - see parts 17 - 27.

This is exactly what I meant. Home tests are totally fine, given there is some reasonable interest from the company already.

Home test is totally fine after a phone call or a two.
However, they are not fine at all just after submitting an application and no real contact.

I think for most tourists the green arrow next to the red light should be suggestive enough.
As an exercise pitted against the anecdote you gave of A.J Jacobs trying to live an authentic life, try this: pretend to be everything you wish yourself to be. Wear those qualities with as much confidence you can muster and then go out into the world and build relationships; wear this new persona that you have created when you start you start a relationship with someone, pretend to show all the qualities you wish you possess the next time you get interviewed for a job, etc.. Then watch yourself and see how it feels to carry the burden of having to constantly pretend to be something that you only wish your self to be. Doesn't sound very enjoyable if you ask me.

Hey <REDACTED>,

My name is <REDACTED>. I’m <REDACTED> years old entrepreneur from <REDACTED>.

I’m currently developing an idea that will combine Neural network with Blockchain. NN is very efficient at deep learning. Such as OCR, voice recognition, and object classification...

I’m currently raising fund for my idea and I decided to do something interesting to make enough money to pay for the server costs.(Due high volume of data, I need to keep high-performance machines open for a long amount of time.)

Your startup is the member of Rockstars Program and they are giving AWS credits as a perk. They offer two options; $15.000 AWS credit for two years or $100K credit for one year.

You can create an AWS account and get $100K credit to your AWS account, I can use the %25 of the credit for myself and sell the other %75 of the credit to my friends in deep learning startup ecosystem. They can pay $15.000 for that.

Which means, I will send $15K directly to you. I'm sure this money can help you to lift your startup to another level. Plus, you don't have to sign any term sheet for this money :)

If you accept my offer, that would be amazing for me. I can use the $25K credit for my research&development and you can get $15K cash and use that money for development, marketing and other expenses for your startup.

You are probably thinking about the risks after reading my offer. Just let me know if you would be interested and I will answer all of your questions before you ask me.

Looking forward to hearing from you.

All Best,
<REDACTED>
that's pretty incredible - I'm no AI expert but it certainly sounds like this algorithm provides an ANN equivalent of neuroplasticity, which seems like a big step.
Asking about project xy is different though, it's more guided. I think it's much easier to answer than the really open ended ones that ask you to pick an incident from all 10-15 years of your work history: the field there is so wide that unless I've specifically considered the question in advance I'm likely to sit there going ummm for a bit.

In general I think the question format favours people with a good memory for anecdotes and story telling ability.
In France, flashing red means an absolute stop, it's like a solid red light but for more dangerous situations. Most often for unguarded tramway level crossing. It's not very common though.

Flashing orange means yield (including to pedestrians, though few people are aware of that).
Funnily enough, I was reading a Scala program the other day and I noted how much it looked like a high-level dynamic Java programming. I think there was maybe 8 lines of typical functional programming code and the rest just looked like imperative code. It seems a waste to use Scala that way to me, but maybe I'm missing something?

Tourists don't come that way. It's very small residential street, turning into a big street with lots of confusing signs and disallowed directions. For me the much worse problem is the other way, coming down the Güntzstraße to the Elbe. The whole crossing is a real city planning nightmare, and I worked in city planning for some years.

What does this service do exactly? Why does it need to have write access to the account if it's only a stat thing?
Lossless video formats (lossless HEVC, lossless WebP) could also be edited with an image editor.
Obviously roundabouts are fine. But an unsignaled intersection? Most intersections do not have nearly enough visibility to make a go vs. yield decision while you're going at full speed and traffic from the left or right is also going at full speed.
Obvious question : is it plan at any point to support Unity3D?
There are certainly many cases where using video instead of GIF makes much more sense. But if you're talking about continuous animation of 10+ elements, then I'm not sure video is a good idea.
We recently optimized electricitymap.org to use GIFs instead of CSS/SVG animations, reducing CPU usage between 50-95 percentage points (depending on setup). In our case, we were animating ~70 arrows causing 100% CPU on many machines, including my own beefed up MBPr from late 2013.
Replacing a traffic light after it already failed is too late.

That allows you to assume that the traffic light is defective, in which case the traffic signs would apply and require you to turn right—but that is exactly what is allowed by the green arrow even at a red light.
Another thing re maintenance: When I saw a TV segment about these lights, they mentioned that the maintenance crew will always exchange all three lights, despite yellow and green never getting used. The reasoning is again consistency: If you told the crew to specifically not replace these two bulbs, there might be a mixup and they would end up not replacing some vital bulbs.

The streetview image posted by advisedwang shows there's also a white-on-blue "must turn right" sign at that junction. This ought to make it clear that you shouldn't wait there to go straight.
User experience is worse with GIF. It takes more bandwidth and consumes more CPU time than a comparable video in cases where video is applicable (and when the other cases occasionally pop up, lossless WebP is probably still a better choice). HTML5 video can be set to autoplay and loop and doesn’t have controls by default:

<video autoplay loop src="…"></video>

Hey, so just to clear things up, because nobody seems to have mentioned it: Is there a sign indicating that there are only right turns allowed? (White angled arrow pointing right on blue background)

As a driver approaching this particular crossing while seeing I'm only allowed to turn right I'm not sure I'd ever notice the light staying red indefinitely.

I don't get it. This is not a wiki. A wiki is a collaboration tool with fast reads and searches and slow writes. This is a simple static site generator, such as jekyll/hugo/..., just without the automatic updates, filewatch or http save triggers.
Those generators have all these features, and much more.

To turn this into wiki, add a js library to allow editing and saves (=> tiddlywiki), and maybe think of markdown javascript renderers (=> reveal-md)
Luckily Germany abides by the international convention on human rights and doesn't have the death penalty so it'd probably be three life sentences. And because of § 54 section 1 StGB they'd be flattened into a single life sentence, which in practice translates to "at least 15 years".

The German equivalent of "life with no chance of parole" would be "Sicherheitsverwahrung" (preventive detention, consecutive to the life sentence) which is an extremely dodgy instrument that is probably in violation of the constitution and the international human rights charter if you look too closely but still used when punishing people who probably should instead be treated for difficult mental health problems.

But I admit that makes for a less funny joke.
Have you taken a look at LabVIEW? I used it pretty heavily back in grad school.

It's a graphical programming language, you connect wires between modules and operators.

Its weird to get used to at first, especially if youre proficient in text-based programming languages, but when you get a feel for letting the program flow drive the logic, you can do some pretty powerful things.

The general idea is that you have a "front panel" that controls user input, and then the back-end programming. Eg, Boolean inputs can be a variety of switches, outputs can be lights and LED's. Floating inputs can be knobs and sliders, outputs can be displays, meters, bar graphs. Very easy to add plots that update in real time.

It's popular with lab research and data acquisition users, since you can easily whip up nice UI's, and many producers of laboratory hardware provide LabVIEW drivers.

You can also easily create advanced techniques or data structures too. Eg, wrap a state machine inside a queue widget, for a "Queued State Machine".

Some drawbacks are that it's proprietary commercial software, and the 'code' can easily become a tangled mess of wires.

In many cases mediocrity is assigned because of the lack of "pedigree". But if the student cares more about the actual learning and content rather than elite badge, it makes sense to come to such universities.
From what I understand, the difference is:

- In Europe a stop sign means that you have to wait until the way is clear. Of course, you normally don't have stops on more than two of the roads crossing. (Theoretically, you can wait forever at a stop, since people on the other roads won't stop and let you through)

- In North America (I've seen it in Canada), you have stop signs on all four roads crossing and you get through in a first in first out turn.

It seems to me that

- the US uses stop signs as a way to slow down the traffic (so, no real meaning), but

- in Europe it does have a clear meaning: "it's dangerous to drive over a crossing without halting". Not only you have to be careful because you have no right of way (the "give way" sign) but you really have to stop and look at the traffic, mostly due to poor visibility (or high difference in speed).
But a stop sign at an intersection with traffic lights is only to be used as a 'backup' for when the traffic lights fail, so it wouldn't be in force?
I had the same approach as this. But not all animations can be made using the transform property, and even if you avoid reflows you can still have a lot of CPU usage with simple animations. In our case, we were moving a gradient inside a div. You wouldn't think this uses a lot of CPU, but if you have enough of them, it becomes a problem - there is apparently a lot of CPU processing involved in re-rendering regardless of reflow. Using the translateZ(0) trick did not eliminate the issue.

Bingo. You're more private if it costs 10x the amount to get at your data. For example, if you have to phone up the records office yourself to find the records, you're not going to wind up with random people being interested in them, generally speaking - but if they turn up on the first page of google when someone searches your name, there's a lot more people are going to find them. Privacy is all about creating friction - similar to hashcash or similar.
Changing the law and checking correct enforcement costs way more in people hours than the cost of operating a single traffic light. People underestimate the cost of regulation. Also, a consistent and simple set of rules should always be preferred and causes less human errors.
