  • Does SQLIO lie when run from a Hyper-V guest on a VHD?

    - by ScottStonehouse
    SQLIO seems like a useful tool. I thought it would be interesting to try to measure the speed difference between a physical disk and a VHD. So I ran SQLIO on the Hyper-V host on the physical drive. Results seemed reasonable. Then I ran it from the guest to test the vhd (on the same physical disk). I expected it to be a bit slower. But instead it was way faster - like 0ms average latency. So I'm trying to learn something here. It seems like hyper-v is fooling SQLIO somehow but I don't understand it well enough to figure it out. It's a dynamic vhd, no snapshots or anything, and the vhd is the only file on the disk. The physical disk is actually a two SAS drive RAID 1.

  • Swing verify code on event dispatch thread at runtime

    - by Jeff Storey
    Are there any libraries that instrument code to verify that methods called on swing components are called on the event dispatch thread? It probably wouldn't be too difficult to write some basic code for doing this, but I'm sure there are edge cases and whatnot that other people have handled. I'm looking for this at runtime though, not for unit tests. thanks, Jeff

  • In what situation should the built-in 'operator' module be used in python?

    - by apphacker
    I'm speaking of this module: http://docs.python.org/library/operator.html From the article: The operator module exports a set of functions implemented in C corresponding to the intrinsic operators of Python. For example, operator.add(x, y) is equivalent to the expression x+y. The function names are those used for special class methods; variants without leading and trailing __ are also provided for convenience. I'm not sure I understand the benefit or purpose of this module.

  • Call private method in Flex, Actionscript.

    - by core07
    I need it in FlexUnit to test private methods. Is there any possibility to do this via reflection by using describeType or maybe flexUnit has some build in facility? I dislike artificial limitation that i cannot test private functions, it greatly reduces flexibility. Yes it is good design for me to test private functions, so please do not advise me to refactor my code. I do not want to break the encapsulation for the sake of unit testing.

  • from one-dimensional to two-dimensional array

    - by Thijs
    Hi again, I have this PHP one dimensional array: Array ( [Female--N] => 11 [Male--N] => 11 [Humans--N] => 11 [Adult--N] => 8 [Adolescent--N] => 8 [Reaction Time-physiology--N] => 6 [Acoustic Stimulation-methods--N] => 6 [Schizophrenia-genetics--Y] => 5 [Motion Perception--N] => 3 ) And i want a new array from this that looks like (i think this tow-dimensional..?): Array ( [Female][N] => 11 [Male][N] => 11 [Humans][N] => 11 [Adult][N] => 8 [Adolescent][N] => 8 [Reaction Time-physiology][N] => 6 [Acoustic Stimulation-methods][N] => 6 [Schizophrenia-genetics][Y] => 5 [Motion Perception][N] => 3 ) Can i use split method on key elements? Little bit harder... i also need to split on the single '_' underscore, i did this to prevent the columns getting mixed up... But the example below doesn't do the job right... $new_array = array(); foreach($MeshtagsArray as $key => $value) { $parts = explode('__', $key, 2); $parts2 = explode('_', $key, 2); $new_array[] = array( 'discriptor' => $parts[0], 'qualifier' => $parts2[1], 'major' => $parts[1], '#occurence' => $value ); So the output should be something like: [0] => Array ( [discriptor] => Female [qualifier] => [major] => N [#occurence] => 11 ........ [5] => Array ( [discriptor] => Reaction Time [qualifier] => physiology [major] => N [#occurence] => 6 Best regards, Thijs

  • Pull row of data from one place in spreadsheet to another

    - by bookcasey
    I have a list of names and their assorted properties. I am trying to find a way to quickly move an entire row's worth of data into a different sheet so I can manipulate it. Currently I can accomplish this by copy and pasting the entire row, but this is not elegant nor dynamic (the number in blue does not update with this method): My ideal solution: A name is typed into the "Name" column. The spreadsheet program pulls the associated row from the "main" sheet into the new sheet. I am currently using Numbers.app, but am curious if this is possible in Excel, OpenOffice Calc, Google Docs, or any other spreadsheet program. Thank you.

  • Why Directly Accesing property is not recommended in OOPs PHP?

    - by Parth
    If I have a class "person" with a property $name and its getter(get_name()) and setter(set_name()) methods, then after instantiating the objects and setting the property i.e. $paddy = new person(); $paddy->set_name("Padyster Dave"); echo "Paddy's full name: ".$paddy->name; //WHY THIS IS NOT RECOMMENDED... In the above code $paddy->name;WHY THIS IS NOT RECOMMENDED?

  • How do i mitigate DDOS attacks on static servers?

    - by acidzombie24
    Here is a slightly different take on DDOS attacks. Rather than a server with dynamic content being attack i was curious how to deal with attacks on servers with STATIC CONTENT. This means cpu tends to not be an issue. Its either bandwidth or connection problems. How would i mitigate a DDOS attack knowing nothing about the attacker (for example country, ip address or anything else). I was wondering is shorting the timeout and increasing amount of connections is an acceptable solution? Or maybe that is completely useless? Also i would limit the amount of connections per IP address. Would the above help or be pointless? Keeping in mind everything is static checking for multiple request of the same page (html, css, js, etc) could be a sign of a attack. What are some measures i can take on a static content server?

    Hi there Can someone explain the differences between an Observable and a ConnectableObservable? The Rx Extensions documentation is very sparse and I don't understand in what cases the ConnectableObservable is useful. This class is used in the Replay/Prune methods.

  • Good suggestions for learning OOP PHP

    - by Doug
    I've been trying to learn PHP OOP and have looked at multiple articles, but have yet to find a good resource for learning. I want to learn from the user of setters and getters, $this-, constructors, and so on...! Can anyone please suggest me something? I noticed MOST teachings leave out the explanation of $this-. I want to learn magic methods, decorators, encapsulation, etc... Feel free to suggest something that I haven't explicitly listed.

  • Python thinks I'm a different IP

    - by Yongho
    I'm trying to set a page that displays the visitor's IP. All the methods I have tried show an IP different from the IP my computer has. I've tried: Looking up http://www.whatismyip.com/automation/n09230945.asp Using socket.getaddrinfo(socket.gethostname(), None)[0][4][0] How can I find the real IP of the visitor?

  • Generic data input form in asp.net mvc application

    - by Diego
    Hello, I have an application that have EF 16 classes that share this information: They all are classes only with a key field and a description. I think it should be a waste if I make a controller with just 1 method just to present a form to fill these classes info, then I was thinking in to make a generic form(with key, description) and dynamically fill the right class through a sort of selection the selected info in any way, any good suggestion or pattern to do that? Where the generic methods should be located.

  • Finding leaks under GeneralBlock-16?

    - by erastusnjuki
    If ObjectAlloc cannot deduce type information for the block, it uses 'GeneralBlock'. Any strategies to get leaks from this block that may eliminate the need of my 'trial and error' methods that I use? The Extended Detail thing doesn't really do it for me as I just keep guessing.

  • What are some fun project ideas for a new Python developer?

    - by Sergio Tapia
    I'm new to Python 3 and so far it seems like a decent language. I really like the string manipulation methods you can use and they are pretty radical. :) I'm stuck however in thinking of a project to do with Python. Is there a site similar to Coding4Fun but for Python? Community Wiki because I think this question is really interesting. :D
