From [0]: Let X be a random variable and g be any function. If X is continuous, then the expectation of g(X) is deﬁned as, E[g(X)] = \int_−∞^∞ g(x)f(x) dx, where f is the probability density function of X. --- For us, with mean 3 and sigma

They use the term 'observe', which typically means to shoot photons or electrons at it. A laser is a common option. This is a pretty reasonable use of the term, as when most people observe anything it's typically by capturing

From the linked paper [0], from the description of figure 2 on page 2, it appears as if the "enclosure, flexible nozzle and gimbal structures" are all 3D printed. The description of how they empirically found a good nozzle shape a

To be fair to Jeff, he was quoting from "Facts and Fallacies of Software Engineering" by Robert Glass [0]. The two rules are very similar, and that's why I think they have the same 'theme'. In one we are talking abo

At first I thought this might have been a repost of some refactoring advice I heard of long ago. A quick google finds a reference on wikipedia [0]. Essentially it goes like this: The first time you implement something, just do it.

Sorry I missed this earlier! I do mean explicitly adding a link to the source from the site itself. Sure, you may not get anyone to contribute, but at least there are no excuses not to. The best feedback almost always comes in the form of a

You should make the source more discoverable, particularly on your 'homepage'. Particularly on a site like this, but also in general, in doesn't take much more effort to write a pull request than it does to write a comment. F

No worries :) Would love feedback on the interface if you are able. The interface feels pretty good with mouse, and seems like it would translate well to iPad, but I won't be able to test myself for a few more hours. I thought about ad

I added some simple click handling to the world map to hopefully enable continued play on mobile devices. Pull request here[0]. By clicking on the north of the map you move north etc. Might be improved by making it relative to the player, r

From the pdf, it looks like there is no patch available for versions <= 6.2.2 From my experience the time to turn-around a product upgrade is typically a lot longer than a security patch. Furthermore, the way the licensing works means th

For those that waited years to get into the private beta, it is now open to everyone! SpyParty is a really fun and unique game, I'm looking forward to seeing the game and its community (which is one of the best I have ever seen) continue to

Maybe it's just because I spend too much time lurking here, but I see a relatively large number of re-posts (or things which I have read before somewhere). I don't usually comment on these articles, however especially when it looks like s

I don't think it's wrong to repost this, I was just providing some background for people who might be interested. When I read this post I remembered the previous one so dug it up; turns out the post references the original source, which I h

This is pretty old (I think it started circulating around 2004? [4]) and was first publicly posted at jasonbock.net[1], although his site seems to be having problems so here is a cached version [2]. The intro posted there is as follows: Th

I think this is a different, unrelated article. In the experiment you linked to the researchers managed to force an electron into a huge orbit, on the scale of millimetres. In the OP's article they are imaging normal Hydrogen atoms. It's ve

I couldn't dig up the original article, but I wouldn't be too surprised if the images were in fact millimetres in size. The images are of electrons scattered from hydrogen atoms, directed onto a plate by an electromagnet. The scattering alm

Knowing which pieces are coming next makes a significant difference in edge cases, but I'm not sure how it would affect the bot in typical play. If you can predict the pieces perfectly you will always[1] perform at least as well as the same

I can second this. I was involved in a relatively large server mod community, primarily as a dev, but as time went on more and more time was spent moderating the community and managing incoming work. By getting involved, even without coding

They don't want it to last longer, that is one of the reasons they chose this specific biopolymer. The splint provides a structure for the airways to grow in/around/within, making sure they don't collapse in the meantime. Once the airways a

I'm not sure what you are trying to say here. Light will travel in the fastest way possible under a certain set of well known constraints. I think trying to apply this same model to how 'mathematicians' cross the road is flawed, although it

by Cogito 13y ago
I think this model is flawed. It tries to boil the problem down to a 'discomfort' level, where what really matters is how long I think I can comfortably stay on the road, how fast I can cross the road, and how long I expect to wait to cross

Are you disagreeing that investment is often needed in order to gain profit? I definitely did not advocate gambling money away, but rather that "an objective view of the situation" requires you "to understand the impact existing investment

It's easy to presume that sunk costs should have no weight when considering the relative value of different options. For many endeavours a certain amount of investment is required before returns are seen - investments in time and money in p

The Double Fine Adventure guys are doing that, for an example of how it could work. They call the second round supporters 'slacker backers' [0]. I would also pre-order now if I could. [0] http://www.doublefine.com/dfapay/

Applying the concept from this problem to the one at hand, try the following scheme: Alice picks an arbitrary point A on the pizza. Bess picks a second point B, and Cath then picks a point C. Cut the pizza from the centre to those points. A
