Theorem of central limit

Hi all

I did a little VI apply the theorem of central limit, it works fine except that it is slow, I know I can use a more powerful computer and it will be faster, but I want to optimize this vi for the minimum time.

can anyone help?

what I do in this vi: 1 - generate numbers of positive integer randomly unigue N (usually 30)

2-i use this 30 integers as indices to select 30 random elements in a table X (which has at least 40 samples)

3. I have the average of the 30 items randomly table X

4 i, repeat previous 3 steps at least 10 ^ 6 times.

5. I draw a histogram.

is there a way to make this faster vi (as possible), even if I change the algorithm, so it does the same thing.

Thank you

Here's what I'd do.

1 M samples, to abour 2 s on my computer.

If you parallelize the outer loop, it will be proportionally faster (total ~0.15s on my 16 core Xeon dual )

This code assumes that the input array is > 30 and you want to select 30 random items. Change to the constantly wired schema to N for the inner loop to change the sample size (or put in place a control on the toplevel diagram).

  • Limit on the expansion of network?

    I have 3 AirPort Extreme base stations, 2 are 5th generation and a 3rd generation. I also have an AirPort Express in the mixture. I have a 3rd generation connected to the FiOS router and I consider that it is the "primary" router Initially, it worked. I had 2 Extreme extending by connecting to the 'main' and the Express has been connected to one of the Extreme 2 extension. This morning, an extreme extension 2 has been disconnected. The error was that he was unable to expand the network. I checked the range and it's well within 100 feet of the central station. I checked the network password and that's OK. I unplugged the other extreme, which extends and restarted then that gave the error. This time, he connected very well to the main but when I turned on the other that I had turned off, he started too give the error of not being able to expand the network.

    Yes, is there as a limit to how many base stations can connect to one to extend a network?

    I checked the range and it's well within 100 feet of the central station.

    100 feet is quite far away... even if you have line of sight between the main airport and the airports of their extension. If there are walls on the signal path, get a good signal for extending airport is going to be quite a challenge.

    The golden rule for the placement of an airport that will extend wireless is the place to a point that is about halfway between the airport and the area that needs more wireless coverage.  For example, if you need more wireless coverage has a few rooms at the other end of the House, extending airport would be located in between the main airport and the other end of the House.

    The reason is that the airport expansion "to extend" the quality and the speed of the signal it receives. If it is located too far from the main airport, then it gets a signal low and slow to expand, so there are few vested benefits.

    I had 2 Extreme extending by connecting to the 'main '.

    Understand that.  If all goes well, the two extremes are found as they are at equal distance between the main airport and each Extender... And each extension's closest major airport that it is another extension unit.

    and the Express has been connected to one of the Extreme 2 extension.

    The Express is unable to extend the signal to a device that is already expanding the network. In other words, you can have multiple devices, the expansion of the network, but each extension must connect directly to the main airport... not at another airport that already is the extension of the network.  In your case, the AirPort Express is actually 'join' the network... so it will work for AirPlay or a printer USB remote... but the Express provides no additional wireless signal coverage in this type of installation.

    For the moment... try turning off all the... from the 'main' airport and all other airports.

    Wait a few seconds and then starts the 'main' airport and run a minute or two

    Turn on one of the extreme airport which extend the network and let it run for a minute or two

    Assuming that the AirPort Extreme that works you just turned correctly, turn on the other AirPort Extreme

    Post back your results, and we are going to discuss options for the Express.

  • Security for the family - windows live essentials vs windows 8 (Central reports seems to be lost)

    I used Family Safety as a component of Windows Live Essentials on PCs of my sons of Windows 7 and the central of the report and the blocking of Web sites has worked well, however it would never connect any other activity such as playing games or use software in general. Since I've upgraded to Windows 8, I realize that parental control is now integrated into the operating system itself and works very well in a sense that it reports properly time spent on a computer in general and it is then broken down by applications. In addition, it also has the ability not only to restrict web browsing, but also to limit the time spent on a PC. However, the reports that I keep getting seem to be empty, and I can check only parental control so I log on the local computer and then run reports. I would also like to stress that my children and I have same connection to our Windows 8 PCs using our Hotmail accounts however 'the link' with central reporting seems to be lost. We are talking 2 different and separate, versions or what I need to configure something?

    Hello

    Family Safety isn't a standard lag time, but the information must be in sync soon once Family Safety detects activity on the computer.

    As for your second question, you can use it as a main administrator account. You can remove the old local account, but you have backup your files, and the new master account must have full administrator privileges.

    Thank you!

  • How can I limit the amount of memory consumed by snapshots

    Is there a way to limit the amount of storage space that each VM is allowed to use through clichés?  For example-, I create a virtual machine with a 50 GB hard drive, using a provisioning.  Snapshots are taken regularly, until the size of the hard disk of the virtual machine plus size of all of his shots is 100 GB.  Assume that 100 GB is all the storage I want to allow any virtual machine to consume on the SAN.  Can I create a parameter through VMware or a tool of management of open source, which will be shot at 100 GB and prevent the snapshots taken once reached the limit of 100 GB?   I'm looking for a parameter that can be defined once and applied to all virtual machines in the environment.

    Thanks for your comments.

    as far as I know, this is not possible. You can set permission on the question of whether a user has the features of snapshot, but you cannot set a quota, etc. You cannot control the number of snapshots, a user might take or how much it can grow by. A single snapshot can develop up to the initial size of the virtual machine.

    VMware has an interesting poll on the management of the snapshot some time ago and some of the questions can suggest future features that could allow a type of instant control growth, etc. We will have to wait and see, but as it is today, it is not configurable. You can probably write scripts to monitor these virtual machines and after reaching a threshold, you can draw attention to it and maybe disable the snapshot feature but that will not stop a snapshot to give more if there are major changes in delta.

  • Opera support & height limit of screenshots

    Hello

    Overall, BrowserLab is a great product. Only, I have two problems with it:

    1. lack of support for the Opera browser (I know this is not popular in the United States, but it is much more popular in Europe, reaching 10 to 15% of market share in Central Europe).

    2 height limit (about 4000 pixels I think?) for the screenshots - why is it necessary? Sometimes Web sites rich in content, the pages are more than that and it is impossible to test.

    Thank you
    Jacek

    Hi Jacek,

    Thanks for your comments. I will pass on your comment about Opera along to our product manager and see what we can do about it.

    As far as your 2nd question goes, the reason is due to a current limitation of the Flash Player which limits the images we can treat 4095 pixels by max aside. We have some ideas how to get around this limitation, but it's going to take a lot of work on our part and therefore is not likely to happen in the near future. I can assure you that this issue is on our radar and is a limitation that we want to get it over with.

    Hope this helps,

    Mark

  • Cannot disable ad followed limit

    I try to use an application called FeaturePoints, which requires monitoring limit announcement is disabled. When I go into the settings, it is impossible to turn off and on. I tried to change the restrictions. Any ideas?

    Hello. You use a profile which may limit your flexibility? If so, it will be located in the settings > general > profile. What happens if you disable restrictions completely?

    Note that "limit followed ad" is a property of your Apple ID, as described here

    "If you chose to activate limit Ad Tracking, advertising platform from Apple will choose your Apple to receive targeted ads on your areas of interest regardless of what device you are using ID." Apps or advertisers who do not use any Apple ad platform are required to check the parameter Ad limit and are not allowed by the guidelines from Apple to serve you targeted ads if you limit active follow-up Ad." (from comments advertising & Privacy - Apple Support)

    Thus, it can be activated on another device so that you cannot turn off the coast.
