Use sharing wizard - how to fix
What is the sharing wizard?
To create a new share on your network file server, you use the New Share Wizard. To be useful, a file server should offer one or more shares — folders that have been designated as publicly accessible via the network.
- In this article we will start exploring conflict between creatures. To get an understanding here, we'll use some simulations and some ideas from an area of math called game theory. (Popular music) Okay, so in our simulation, food will appear every day, and then blobs appear and go out to eat the food.
We use the same rules of survival and reproduction as in the previous articles. If you eat one piece of food, one creature can survive until the next day, and eating two pieces of food allows a creature to both survive and reproduce. The difference in this simulation is that food is delivered in pairs.
Each creature randomly picks a pair of foods to go to, so they may have the pair all to themselves and take home two foods and then breed, or another creature might find the pair at the same time this happens they have to somehow figure out how to split things up. We start by saying that we just have one possible strategy for creatures meeting each other, they will just share, each have a piece of food and go home to survive until the next day. And because this strategy is so beautiful, we give it the name 'dove'. , now we're adding a new strategy called the hawk strategy.
Hawks are more aggressive. When a hawk meets a pigeon, the hawk will seek the same piece of food as the pigeon, eat half of it, and then quickly eat the other piece of food, to take it for itself. This half food complicates our rules of survival and reproduction a little.
In this situation, a pigeon will end the day on half a meal, so it has a 50% chance of surviving until the next day. and the hawk ends its day with a food and a half so it will surely survive and also has a 50% chance to reproduce, so it looks good to be a hawk but it is also risky when two hawks meet themselves, they fight, and the fighting is exhausting. At the very least, they use a lot of energy and can get injured too.
So when hawks fight, everyone gets a piece of food, but they give it up from so much energy in combat that they immediately consume all the benefits of eating and effectively go home without food, which means they will not survive. So, now let's try adding a hawk creature to our simulation and see what happens a good time to pause and predict what you think will happen. (light music) Okay, it looks like we have a mix that is about half and half way around.
And there are also fewer creatures overall, even with the same amount of food, an example of how natural selection does not necessarily work for the benefit of the species. And to cover our basics, let's try starting with all of the hawks. (Popular music) Okay, not too surprising, they are tearing each other apart, and your maximum population size didn't even reach half the population size of the pigeons.
Now, if we add a pigeon to the mix the next day, what do you think will happen? Okay, so it took the pigeons a while to gain a foothold, but at some point we get into a similar situation with a fluctuating mix of hawks and pigeons. So why do we care? Well this is a situation where survival of the fittest does not help us understand what is going on. We translate our rules of conflict from earlier into a table.
If two pigeons face each other, they each get a feed. When a pigeon faces a hawk, the pigeon gets half the food and the hawk one and a half or three-half food. And if we reverse perspective, when a hawk faces a pigeon, they get three and a half.
And when one hawk faces another hawk, everyone will end up with zero after wasting a lot of energy in battle. Now that we have this table, let's imagine blobs that can choose which strategy to play. Let's say I control the blob on top and you control the blob on the left.
Say you know I a. play hawk strategy which i am of course what to do? Well, you'd better just go back and take half your food. This could be annoying as it feels like I'm going to win somehow and you might be tempted to challenge me and also play hawk to teach me that I can't just push you around.
That might make sense if we played this game against each other over and over again, like two people could do, and that's what we'll talk about in future articles. But in this situation we're just those simple blobs of no social structure that interact once, and even if we meet again, we won't remember, so the only thing that counts is how much food we take home with us, and when If you want to maximize your chances of survival and reproduction you play pigeon. Discretion is the better part of valor here.
Let's record this by drawing an arrow. If we're in the right column because I play falcon, the situation in the top right box is the best you can do. Okay, in the other case where I'm not that mean, you know I'll be playing pigeon strategy.
In that case, you'd better play falcon, you may be tempted to think about the future and want to reward me for playing nice and playing pigeon myself, but we're just these really simple blob-creatures who may never meet again see. So if you want to maximize your chance of reproducing, you will play Falcon. And we can take this up with another arrow.
To complete this table we can flip the perspectives and think about what to do in response to you, which I won't go through in this detail in this case, it's the same reasoning. But we would get similar arrows in the ranks here. These arrows all indicate more beneficial strategies, and the interesting thing is that there are two stable situations: either you play falcon and I play pigeon do, or you play pigeon and I play falcon.
If we find ourselves in either of these two situations, each of us would be worse off choosing a different strategy. And by the way, this way of analyzing decisions is called game theory, which is a whole field of mathematics. In a situation where no one benefits from changing their strategy, it's called a Nash Equilibrium, named after John Nash who some would say has a lovely mind.
So the best strategy is not a hawk or a pigeon. It's the opposite of doing what your opponent is doing. When there are many of the pigeons it is better to be a hawk, and when there are many hawks it is better to be a pigeon.
There is a certain equilibrium proportion of pigeons to which the population is always drawn. Great, so we have the most important conceptual point below, but we can deepen our understanding by calculating what that equilibrium fraction should be. The population will be in equilibrium when pigeons and hawks have the same expected average score in a competition.
Correct? Equilibrium is when, on average, we don't expect a change in one direction or the other, so we can't have a better strategy. They are equal. Our goal is to find the fraction of pigeons that meet this requirement.
On our way there we first calculate the expected average score for a pigeon in a hypothetical example. Let's say where the rest of the population is 90% pigeons. So let's see, a pigeon has a 90% chance of meeting another pigeon, in which case it receives the pigeon-pigeon payment for a feed Pigeon also has a 10% chance of encountering a hawk, right? That's just the rest of the creatures.
In this case, she only gets half a meal. So if a pigeon encounters another creature when the rest of the population is 90% pigeons, it receives an average of 0.95 food.
This number is pretty meaningless on its own. But once we have calculated the expected hawk value, we can compare the two to see if the equilibrium condition is met. Let's find out the expected falcon score.
It might be good to take a break and try this yourself to make sure it all makes sense. Maybe even rewind to watch the pigeon part again. Okay, like before, the rest of the population is 90% pigeons, and for one pigeon a hawk will get one and a half food for three halves.
And again there is a 10% chance of meeting another hawk, in which case our hawk goes home without food gives an average of 1.35 food. Notice that 1.35 is more than 0.95.
So with 90% pigeons, hawks will do better and we expect the proportion of hawks to increase in the next generation. So it's not a balance. Not 90%.
Now to find out which fraction of pigeons meet the equilibrium condition, we can write the fractions of pigeons and Hawksas variables instead of just guessing certain numbers. And now you could say, 'Wow, that's a lot of letters,' which is a fair point, but we're almost there and our next step is to get rid of one of those letters. It's been a nice treat.
Pigeons and hawks make up all creatures, so their factions must add up to one. And that means we can replace the lowercase h with one minus the lowercase d. And now the expected pigeon and hawk values are both written as functions of one variable, and the same variable, so we can graph them on top of each other, the expected values are the same when the graphed lines cross, and in fact the equilibrium condition is at 50% Pigeons met.
And if we run a simulation with a lot more creatures than before, unfortunately too many to animate, the randomness is smoothed out a bit and we can see that the prediction is true, just to verify what we are working on already thought. But the fraction of pigeons will not always be half. It depends on the numbers in our payout grid.
The most interesting number to play with here is the hawk versus hawk payout so far we've said the hawks get a piece of food but waste all of the F's energy.But what if they only use most of the energy instead waste, not the entire, and go home with a score of 1/4? When we put that in, we see the population moving towards 1/3 pigeons. We can see this in the simulation.
At this point, congratulations, we have a fairly detailed understanding of how hawk and pigeon populations work. And as fundamental as this model is, with just two simple strategies, it's a powerful starting point for analyzing real-world behavior. And before we get started, I'd like to give you some teasers on how we can build on that to reflect reality in future articles First, creatures in the real world can play more than one strategy.
So instead of having their behavior entirely determined by a single gene, our creatures could have multiple genes that affect their behavior, giving them different chances of being hawk or hawk Playing pigeon. The game theory term for this is mixed strategies. There may also be more complex, conditional strategies that act differently.
For example, there could be a strategy that fights hawks but is nice to pigeons. And there could also be a strategy that tries to threaten a fight but runs away when the going gets serious.What happens with these types of strategies can help us understand why some animals make threatening representations while rarely actually fighting, or have ritual fights that usually don't harm anyone.
Next, most conflicts are actually asymmetrical. Everyone has an equal amount to win and lose, and that all creatures are equal. But when that changes, we can begin to understand things like territorial behavior and dominance hierarchies.
Falcon payouts are getting less and less bad. Let's say we get to three quarters. Now the drawn lines don't cross at all.
There is no balance. At this point, even if you know you are facing a hawk, eating three-quarters of the fight getting ing is better than half what you get when you are nice. So these arrows should actually turn around, and it only ever makes sense to play falcon.
We get into this tragic situation where everyone struggles all the time, even though they would do better if you could just cooperate. This type of situation has a special name. It's called the prisoner's dilemma.
It can feel kind of grim, but there are ways out that we'll talk about in future articles. See you then. Okay, now I have a few people to thank you for.

How do I enable sharing Wizard in Windows 10?
To enable it, open Folder Options, go to the View tab, and, in the list of advanced settings, check the 'Use Sharing Wizard' option. Then click or tap OK to apply your setting.
Hello, today I'm going to show you how to connect multiple computers on a local network with Windows 10. If there are computers with Windows 7 or Windows 8 on the network, the sharing settings for them are configured similarly to those configured in Windows 10 on a computer with Windows 10, will be displayed without problems in the network environment on Windows 7 computers and vice versa, the main thing is that network detection is enabled on all computers computer number First, you have to make the computer visible on the network click on start settings network and internet then open the network and the sharing center then change advanced sharing settings Now I have to say that what you see on your screen may be different from mine because Windows 10 is constantly updating and its functions may change their appearance, here we can see that the current profile on my computer is guest or public network, but to connect to the local network it is necessary to connect to the private network, it is advisable to install this P. rofilon only if you are connected to your network and with your router which is reliably protected and now I will change these settingswe close these windows in the Internet areaclick here and change the network profilereopen the network and the Sharingcenterthen change the advanced sharing settings now see we that my current profile has a value private private should be noted here come to network detection and go to automatic configuration for network devices in this section it should be noted that we are not interested in the guest room when sharing files and printers, then we open the tab All Share networks so network users can read and write files and shared folder streaming is disabled by default, but you can enable and enjoy music photos and articles on computers on your network.
Here we leave 128-bit encryption for next If you log in to this computer with a password, you have to activate the password-protected release If you do not have a login password Deactivate password-protected release i disa ble this function here the settings are complete click on save changes and close this window snow we have to find additional system parameters for this we open Right click on this computer and select Properties as I said after the latest updates some of the functions of Windows 10 now look different if you have not received these updates, then this window opens and in the top left you have to click Advanced Clicking System Preferences in my window I'm going to click Additional System Parameters here on the Computer Name tab You can change its name and give the workgroup a different name. I open the Change tab and write a new name PC number oneclick ok the system asks to restart the computer but we need to change another setting now we open the remote tab the check box should be checked to allow remote assistance connections to this computer and check Allow remote connections to this computer click on Apply to activate remote desktop, opens a port on the computer that is visible on the local network click ok and you have to restart your computer for the changes to take effect. After that, you need to make the same sharing settings on other computers.
If you do this, all computers from the network neighborhood will be immediately displayed in Explorer on the Network tab. Computer number one is also displayed together with other computers Computer number two and so I made the same settings on the second computer Step by step I repeated all the settings they do not differ at all from what you have already seen here and restarted now we see what igotopen explorer network clicks and we see how the connection with all devices from the network environment is made here we see computer number one and number two that I have connected to the local network, the third computer was previously connected. Double click on computer number two and here we see the user folder which by default has several folders for exchanging data on a shared network where you can copy and delete files delete To see how it works, open the s Hared Documents folder and copy You the program shortcut from my desktop there you will be reminded that this was done on computer number two computer number one now on computer number one eye open explorer click network click computer number two open the home folder then click general documents and general here we see the shortcut of the program that I placed earlier in it, in addition to these folders on the local network, you can share any file folder or disk and also configure access to the printer on your computer, but this will be a separate topic and so set up we just e into local network between two Windows 10 computers and we got it right, thank you for watching
What are the two permission levels within the Windows Sharing Wizard?
Windows 10 uses three different share permission levels — Read, Change and Full Control. Below is a summary of what these share permission levels convey to bother users and security groups.
