## Accurate hiking maps of Austria

I’m going to Austria for hiking. In Switzerland, we have very accurate maps that are available online for free. Is there anything similar for Austria? I couldn’t find a central place that covers whole Austria and includes all the information that the Swiss maps include: I would be especially interested in colored terrain that is more than 30° steep and populations of alpine ibex.

## api – How accurate are these Bitcoin price predictions, and do they have a JSON blob?

I’ve found this: https://longforecast.com/bitcoin-price-predictions-2017-2018-2019-btc-to-usd

Very interesting short-term numbers. I hope they are right.

However, for me to actually use these numbers in an automated fashion, for example to display “how much I will own in X months”, I need a more reliable data format than this HTML table. I can’t find a JSON blob/API.

And how accurate have they been historically? Is there a better source for Bitcoin price prediction?

(No, I’m not going to “waste my kids college fund” based on the advice, but it would be fun to have a little automated number showing how much I will have if things go as predicted in X months.)

## unity – How to align prefab to a accurate position with the best practice?

I’m making a plumber game, I have a pump prefab, and pipe section prefab, which allows the user to connect the pipe during game, the pipe needs to be connected seamlessly during game, which means pipe prefab needs to be aligned in pixel level, please check below

User needs to add more and more pipe to connect the with each other, pipe is fixed length prefab.I’ve got choices,

1.Is the pipe prefab instantiated during game play a good practice? Because it might have many pipe prefabs, if the pipe goes a long way to another position, than there will needs to be so many pipe prefabs, compared to have procedrually generated pipe mesh during runtime, then a long pipe will not have to be cut off to the same small pieces?Which is good way to adpot?

2.If I use the same pipe prefabs to fabricate the piping system, how to accurately connect each other in pixel level, I can make the whole piping system in blender, then cut the system into pieces as my prefabs, then import to Unity as my first choice, this can do pixel level connection, but it seems to have better choice solely solved pixel level connection in Unity?

3.If I do it by generating the mesh during game play, then it could be complex especially it is hard to make elbow pipe mesh during runtime, or could you please advise me of some known library or package can do the work?

## machine learning – Is there an accurate way to convert frequencies of the Stupid Backoff language model to probabilities?

We introduce a similar but simpler scheme, named Stupid Backoff, that does not generate normalized probabilities. The main difference is that we don’t apply any discounting and instead directly use the relative frequencies (S is used instead of P to emphasize that these are not probabilities but scores)

That’s a quote from the paper that introduces the Stupid Backoff language model. https://www.aclweb.org/anthology/D07-1090.pdf

I’m curious, is there an acceptable/accurate way to convert those frequencies into probabilities?

Frequencies are acceptable for prediction and ranking predictions by their likelihood, but it’s not acceptable if you want to generate text with accurate probability distributions.

Is there an attribute of the algorithm that makes it such that normalizing the frequencies into probabilities isn’t an accurate reflection of the probability dist

## exchanges – Are the transactions displayed on “BitListen” really accurate?

Over the years, whenever there’s unusual Bitcoin activity, I look at: https://www.bitlisten.com/

But can these transactions really be accurate? I just saw numerous 100+ BTC ones, and just now a gigantic one of 946.92 BTC (!!).

According to my exchange rate calculator, that is:

``````BTC 946.92 = \$22,731,761.52 USD
``````

Almost twenty-three million US dollars… at once?

I realize that a lot of money is being traded right now, but even if somebody has that many Bitcoin to trade, would they really do it all in one go? Isn’t that very risk? Wouldn’t you split it up into at least hundreds of different transactions?

I don’t understand what kind of person or entity would make a single transaction of such a huge sum. Is this really accurate or faked somehow?

## calculus and analysis – Accurate numerical calculation of nested integrals

I’d like to accurately (numerically) compute nested integrals of the type $$I(a;k) =left( prod_{i=1}^k int_0^infty mathrm{d}x_i right) exp left( – frac{1}{4a} sum_{i=1}^k left( x_i – x_{i+1} right)^2 – frac{a}{2} sum_{i=1}^k (x_i + x_{i+1}) right)$$ where $$a > 0$$ is a parameter and $$x_{k+1} equiv x_1$$. For $$k = 1$$ and $$k = 2$$ the integrals can be done analytically, but as far as I’m aware no closed-form expression is known for $$k > 2$$. So far I’ve written the following naive NIntegrate command:

``````int(a_, k_) := NIntegrate(Exp(-1/(4 a) (Sum((x(i) - x(i + 1))^2, {i, 1, k - 1}) + (x(k) -
x(1))^2) - a/2 (Sum(x(i) + x(i + 1), {i, 1, k - 1}) + (x(k) + x(1)))), ##, WorkingPrecision -> 30, PrecisionGoal -> 5) & @@ Table({x(i), 0, (Infinity)}, {i, 1, k});
``````

This command, for $$k = 3$$, gives an error (a `NIntegrate::slwcon`) when $$a$$ is small enough, $$a lesssim 1/3$$. For $$k = 4$$ the error appears when $$a lesssim 4/5$$. But even for larger $$a$$ when the error message is absent, I’m not sure if the command is computing the integral correctly. I’ve tried increasing the WorkingPrecision (as suggested by the error), but I’m finding it doesn’t help. The other suggestions are not relevant to this problem, I believe (no singularities or heavily oscillations, and the integral is not zero).

## Should Canon 5D mk II autofocus be accurate enough for a f/1.2 lens?

According to this Blog post by LensRentals.com owner Roger Cicala, the 5DIII has less than 1/2 the standard deviation of the 5DII with regards to Phase detection Auto Focus. But to get that additional benefit, one must also use Canon lenses introduced since about 2010. All of the testing was done using the center focus point.

In general, using the center focus point should yield faster, more accurate focus with faster lenses such as the 50mm f/1.2L and f/1.4. The 5DII can be an exception to this rule. When shooting in AI Servo AF, if C.Fn III-07 is enabled, there are six small AF Assist Points clustered within the spot metering circle that are active in addition to the Center Focus Point. The location of these six AF Assist Points are not indicated in the viewfinder! Yet the camera may be using one of them pointed at something that has higher contrast than what is located behind the square in the middle of the viewfinder when it decides the focus distance.

Here’s the Map for the 5DII’s focus system.

The entire series will tell you just about everything you’ve ever wanted to know about phase detection AF accuracy and consistency.

## headphones – Can’t play accurate audio direction in games using 3.5mm audio jack?

recently I tried to run android games on my laptop in Gameloop emulator (shooter games in general). after playing a couple of minutes in PUBG Mobile with the same headphone on, I noticed that the audio direction and footstep sound are far more clear and accurate than what it sounds on my mobile (I own a non-rooted Xiaomi Mi 9T Pro with latest MIUI 12 on it, and an off-brand over-ear headphone “beats” that not exist on the internet BTW.).

I saw this question on this site, and if I’m not wrong, it says that I cannot play more than 2 channel audio on a 3.5mm headphone jack! But since I was able to hear more accurately on my pc with the same 3.5mm audio jack(aux), I thought there could be a solution for that.

Is there something I can change on my phone to make it output sounds like my pc, or even make it a little more accurate?

another thing I want t mention is, my mobile doesn’t even split left or right channel while playing surround videos on youtube. I cannot tell if the sound is completely from the left channel or right because both sides of the headphone play the same sound.
