-Here in Norway, every speed camera needs to be advertised by signs in order to let the driver know he's being monitored. Kind of defeats their purpose, as the idea is not to ensure people drive past the cam under the posted limit; it is to make sure they obey the posted limit, period.

Speed cams would be most effective if they were hidden all over the place. (Or used to record average speed over some distance, which is a most effective way of ensuring people observe the speed limit!)

The latter, though, will get the privacy nut in me annoyed unless the authorities flush the record of you passing immediately after verifying that you drove at or under the speed limit. Speed cameras are excellent surveillance devices, after all.
In this case the fundamental idea is not especially complicated, but the math may make it seem more complex than it is to somebody unfamiliar with the notation/vocabulary.

Imagine the case where an input dataset has three dimensions: each piece of input data could be represented as a point in 3D space. We want to classify each point with a category. Imagine a cube containing all such points, and imagine the cube was subdivided into many tiny cubes of the same size. If these tiny cubes were sufficiently small, then each cube would only contain points belonging to a single category (sufficiently small cubes would only contain a single point, making this trivially true). We could then assign to each cube a category based on the category of the points in it, then if we wanted to classify a new point, we'd just check what cube it's inside and look up the category of that cube.

The above process doesn't scale well (would be too slow in practice). An alternative is, rather than subdividing the cube into tiny evenly-sized cubes, we use an iterative process, starting with the whole cube, finding an ideal dimension along which to split it, splitting it (subject to the constraint that splitting it wouldn't make the children too small), then repeating this process with the two 3D rectangles that resulted from splitting the original shape. This could produce extremely long, thin 3D rectangles however, which might not generalise well to new data, so we cap the aspect ratio of the child rectangles so they can't get too thin. This approach may leave some areas of the original cube unclassified, so for each such area we find the category of the 3D rectangle that the unclassified areas touches most, and assign its category to the unclassified area, then repeat until there are no unclassified areas remaining. The end result approximates the result of subdividing the cube into tiny cubes, but is significantly faster to produce.

The above approach is roughly what's described in the paper, except they describe an n-dimensional hypercube rather than just a 3-dimensional one, and provide more detail on how to determine the ideal axis along which to split a hyperrectangle into child hyperrectangles.
I think the thing is, at any given time, there may be a thousand people trying to do the same thing at a certain level of competency, with only a few actually managing to gain any traction due to a combination of luck or timing.

Then these people say they were much better than the others, while objectively they were executing at about the same level.

If everyone does everything right, there will still be winners and losers.
I've been lurking on Hacker News for (at least) two years before deciding to participate: I would visit the homepage daily, read some interesting news and comments, and finally leave the site.

It's pointless to comment if one cannot add new information, perspectives, arguments, or humors to the thread, as a result, one really needs to make an effort to engage in the discussion. In practice, it means you'll need a proper keyboard, and a fast Internet connection to search for references. At least, at there, or at Reddit, or even at 4chan, this principle applies. I mean, you can make pointless comments, but you'll lower the SNR of the entire community, or your comment will be ignored or filtered on 4chan, or downvoted (or not getting votes) on HN/Reddit/Slashdot.

There are other places where the barrier-of-entry is lower, like the comments section below the stories on "ordinary" news websites (not HN), etc, but make an comment is even more pointless.

I guess the best counterexample I can think of is Twitter. It's no more than 140 chars and highly personal, so making a knee-jerk comment is common, and you can use a mobile phone instead of a proper computer to do so.
There's also your attention surface. I typically read threads/posts from a variety of communities, but might prefer to reply only on some, and lurk on the others. I'm sure this is true for a lot of people, from anecdotes I've heard.
Known and well-signposted speed camera on dangerous turns, close to schools or kindergartens would vastly improve street safety.

Unfortunately most German(!) street cameras are placed to surprise the driver, causing nearly continuous disruption even for those who don't speed. Their destabilizing effect on traffic can be observed quite easily as people suddenly brake, make light signs to warn others, surprisingly change lanes (because of the sudden speed reduction), etc.

This is because in Germany the money goes to the local authorities.

It doesn't help that placing and maintaining them is pretty expensive (and often outsourced with profit-sharing). Local authorities and private partners have little incentive to reduce their income per device just to increase road safety.
The thing is that among "actual people with firsthand experience" the ones who blog are probably outliers as well, so the original principle still holds.

Deletionism is the thing that will kill Wikipedia, by deleting itself and gradually narrowing the circle of permitted contributors.

There are some situations where the non-English Wikipedias have far more information than the English ones though, because of how "notability" works.

I use the bicyle lane when there is one. But in the city with cars parked on the road side I simply have to keep 1 meter distance to the side to avoid dooring (google it!) and that puts me into into the middle of the lane. Which in turn means that cars behind me have to use the oncoming lane to overtake me. If I were cycling more to the side the cars behind me a) wouldn't slow down b) overtake me with little to no space around me and thus endanger me in all those unexpected siutations on the road.
Also, who said those roads are just for cars? Roads have been around since roman times, unlike cars.
Not able to edit! But i meant NOT worth the switch.
Wikipedia does a lot to prevent new users participating. The mediawiki software is very confusing and has a lot of different functionality crammed in to the same page edit tool that doesn't even make sense.

I attemped to create a page about a slightly obscure file format with all the information I had found while developing with it. I linked to all the sources I found that helped me understand it and my submission was rejected because my sources were not academic enough so I removed those sources and added the only official source in existence which is a zip file containing code examples and example files. My second edit was rejected for not sourcing all of my info.

Literally the only info available is the zip and forum posts. I mainly used the forum posts while learning and verified it against the data I was seeing in the file. How am I meant to share this info for others to benefit from? If I make it in to a blog post it's not an acceptable source but if I post it as a PDF and pretend its some wanky research paper then it probably would get accepted.
This is just Epic trying to get some good press.

Instead Steam/Valve should fund open-source game engines and development tools. For them it is a complement to their business model, so the incentives are aligned. And they can ensure a smooth path to market for the game developers. Everyone wins (well, maybe except for Epic/Unity).

There doesn't appear to be any empirical justification for anything the author has done here. Does anyone really believe that 1/ the "stock' of ideas can be measured by a real number and 2/ national output is proportional to some power of the "stock" of ideas?

Like, how do you even measure an idea? The paper feels like the author has done a load of maths and shoehorned one particular interpretation onto his equations.
I'd say that many times, that's true of Swedish topics too. I wonder how well that fits with eg Wikipedia in other languages where English may not be so fluent though, eg German?

But if someone is putting others at danger, they shouldn't be treated with mercy just because they are poor. If you drive dangerously why does it matter that you need your car to feed your family? It doesn't and it shouldn't.

Yes the consequences are worse for a poor person, but that's like saying that consequences of murder are worse for a poor person - if they go to prison then their family is now at risk because maybe they were the only money making person in the family. Rich person's family is probably going to be fine. But does that mean that poor people should be punished less for murder? Of course this is hyperbole now, but I think the same principle applies.
Everyone is speeding everywhere in Belgium. We also get a lot more casualties (by inhabitant, by vehicle, by kilometer, any metric you take) than France. France has about 30% less deaths than Belgium, and gives right of way to people coming from the right. The road rules are almost exactly the same between the two countries.

If anything, I think it just shows that speed limits are not enforced well enough (and I think it should start with switching to a points permit) in Belgium. I also personally find them often too high, with 70 often being allowed in urban areas outside the core parts of towns.
There's a truly simple trick that makes you invisible for the attempt to use them as money machine. It's incredibly simple. Do not exceed the speed limit. I tried it. It works!

You Danes generally speak real good English right?

I think that may be a problem for Wikipedia in such countries. People can read/write English good enough that they just go directly to English.

It's pure speculation on my end though. But I'm a non-native English speaker but I never go do my native language's Wikipedia.
the speed camera is there to protect cyclists and pedestrians, not the driver or his car.
> We need car control every bit as much as gun control, and speed cameras are a big part of that. People die when drivers are left unchecked. Disproportionately, it's people not inside cars.

I agree completely.

To be honest, from a safety perspective, I would be happy if speed cameras were integrated with street lighting so that basically every stretch of road was covered by speed cameras.

That said, I think that penalties should be in the form of a points system that ultimately results in losing your driver's license if you consistently speed. Financial penalties seem to disproportionately penalise the poor.
I wish there were also minimum safe distance cameras.
I'm kind of a lurker as well. I read HN comments to gain a broader perspective on issues. Sharing my own thoughts on the matter doesn't really help with that.

Of course, sometimes when reading comments I get the feeling that you people are all entirely, inexcusably wrong, and I feel an urge to set the record straight. Normally on HN, it doesn't take long for someone to step up and explain exactly what I was thinking with an eloquence I couldn't have matched. And the world is right again. :-)
I check the site maybe once every couple of days, and I don't comment or reply because it usually seems like the post is "old" by then and the discussion has died down.

Your comment now is marked "5 minutes ago" and seems game for a reply, but later today when it's "5 hours ago" or longer, I'd feel like it has expired and any reply would be lost and never seen.
I have lurked on forums before. Usually its because I just check them sometimes on my phone and can't be bothered making an account.
Wikipedia entry on ayurveda:

Although laboratory experiments suggest it is possible that some substances used in Ayurveda might be developed into effective treatments, there is no scientific evidence that any are effective as currently practiced.[11] Ayurveda medicine is considered pseudoscientific.[12] Other researchers consider it a protoscience, or trans-science system instead.[13][14] In a 2008 study, close to 21% of Ayurveda U.S. and Indian-manufactured patent medicines sold through the Internet were found to contain toxic levels of heavy metals, specifically lead, mercury, and arsenic.[15] The public health implications of such metallic contaminants in India are unknown.[15]

Time is a big factor: usually I can only spend some 30 minutes per day for HN/reddit, barely enough to only have a look at a few of the interesting posts, let alone contributing.

I plan to go there one day, and see it with my own eyes. A lot of cases presented are "french tech" startups which means these startups are invited with the money of the France taxpayers. It became a subject of mockery in France because institutional folks who never launched anything give business lessons to entrepreneurs and we see the result in Vegas each year.
Even on a social network such as Facebook, a minority creates content. By creating I mean taking their time to write something or post their own photos. Most just share links. For a website like reddit or any other kind of site relying on user content, you can see that as an opportunity. It's not that 97% are not posting. It's that your user base attracts 30 times more other users to consume the content and therefore giving you great traffic.

It's almost a natural law - IME lurkers outnumber active commenters on forums by a minimum of 10:1.

Not commenting is the natural state for most people. Maybe the question isn't why these people don't post, but why active commenters do.
Also the ability to understand and check the performance impact of these choices. For example at a old job on an embedded motor controller the previous engineer had learned 'floats are slow never use them on a microcontroller' and went and removed them from the code wherever he found them. However in the motor control update loop this meant using longs (or possibly even long longs, I don't remember) in a couple calculations. A quick check with a pin toggle showed this was significantly slower than just using floats.

I'm an ME who went into embedded systems, so I'm not sure what qualifies as low level for a web developer and if checking timing using an oscilloscope or saleae is feasible for the type of work OP wants to do. But even just looking at the assembly would have made things obvious in my example.

EDIT- This made me realize that a rudimentary understanding of the assembly language for your architecture will be very valuable. Doesn't have to be enough to actually write any code in it, but it's great to be able to take a look at what was generated when things are acting weird.
I worked quite a bit with F# and Scala.

I really like F# pipelines and function declaration syntax.

On the other hand I've found Scala's case classes cleaner than F#'s (maybe that's because I am coming from an OOP world).

Additionally F# has a cleaner pattern matching compared to Scala.

Both languages have very good support for actor model concurrency (love akka actors and .net agents)

I think that if F# would have had a rich ecosystem the way Scala has, it could become a real contender.

(my 2 cents on F#)
are you a road engineer? a safety specialist? have access to the stats of the area? know that ppl didn't complain for noise?
What answers did you get from other professions?
How can you think of a continuous time signal as a polynomial though? I don't know of a continuous time analogy. It seems like the polynomial only works for the discrete case. And FIR filter convolution is rarely computed by FFT in FPGAs (in stream applications).

Look at a system doing DSP for example. Let's say you have an input RF signal that goes into an analog band-pass filter, a mixer, an analog low-pass filter, a DAC, and a FPGA. The FPGA implements a FIR filter - lets say a Hilbert transform using a distributed arithmetic algorithm. You are getting envelope information out of the FPGA. There's no FFT anywhere in the FPGA to compute this filter output.

You are seeing some weird noise in your DSP output. You dig a little by looking at the output of the DAC and then look at the FFT magnitude log10. You see some suspicious spurs popping up, but at really strange discrete frequencies. You show the spectrum to an RF engineer, then you two go to the lab and put an analog spectrum analyzer on the input to the DAC. Sure enough, there are mixing products of your input carrier, mixer frequency, and sampling clock frequency. The weird spur frequencies make sense now - you are seeing folding of the mixing products from the sampling. You tweak the sampling clock to move the spur digital frequencies.

In that long but real world example, I don't see anywhere here where thinking of things in terms of polynomials would be helpful here. It's also going to lead to confusion of terminology with your RF engineer - they tend to think continuous.
Of course not, there's nothing wrong with not posting. My question was just out of curiosity for why people never feel "compelled" (not a great word here) to post while actively browsing quite a bit.
