  • HT create a new vector in data frame that takes correlation of existing vectors

    - by Milktrader
    I have a time series of two indexes, with each row representing the closing price on the same day. I'd like to go to row 30 and lookback over the last 30 'days' and calculate the pearson correlation. And then store that value in a new vector. Then, repeat the calculation for the entire time series. It is a trivial task in Excel, so I'm convinced it can be done in R. I don't know the method to use though.

  • Should an NSLock instance be "global"?

    - by Alex Reynolds
    Should I make a single NSLock instance in the application delegate, to be used by all classes? Or is it advisable to have each class instantiate its own NSLock instance as needed? Would the locking work in the second case, if I, for example, had access to a managed object context that is spread across two view controllers?

  • Extracting attribute data from a raster

    - by user308827
    Hi, I have a raster file (basically 2D array) with close to a million points. I am trying to extract a circle from the raster (and all the points that lie within the circle. Using ArcGIS is exceedingly slow for this. Can anyone suggest any image processing library that is both easy to learn and powerful and quick enough for something like this? Thanks!

  • NSPredicate of special characters - iPhone

    - by ncohen
    Hi everyone, I'm trying to make a predicate that includes special characters For example: [[myIngredients filteredSetUsingPredicate:[NSPredicate predicateWithFormat:@"name BEGINSWITH[c] %@", [alphabet objectAtIndex:idx]]]; Here I will get all the ingredient which starts with (let say for idx = 5) 'e'. As I have to do my app in english and french, some ingredients start with special character like 'é' or even 'œ' for 'o'. How can I include these special characters in my predicate? Best

  • Powerbuilder : How to compare the old value and new value of a column in data window

    - by Archangel
    Suppose I have a datawindow object which is attached to a datawindow control named 'dw_detail". This object uses grid presentation style and has a database column named 'found'. Now when a user modifies that column's value, I want to compare it with the original value that was fetched from the database. I know I can access the value of that column as 'dw_detail.object.found[row_no]'. Now I am trying to access the original value of the column as 'dw_detail.object.found.original[row_no]', but it is not working. It is not giving any compiling error, but when I debugged, 'dw_detail.object.found.original[row_no]' contains no values. How can I access the original value of that column?

  • If attacker has original data and encrypted data, can they determine the passphrase?

    - by Brad Cupit
    If an attacker has several distinct items (for example: e-mail addresses) and knows the encrypted value of each item, can the attacker more easily determine the secret passphrase used to encrypt those items? Meaning, can they determine the passphrase without resorting to brute force? This question may sound strange, so let me provide a use-case: User signs up to a site with their e-mail address Server sends that e-mail address a confirmation URL (for example: https://my.app.com/confirmEmailAddress/bill%40yahoo.com) Attacker can guess the confirmation URL and therefore can sign up with someone else's e-mail address, and 'confirm' it without ever having to sign in to that person's e-mail account and see the confirmation URL. This is a problem. Instead of sending the e-mail address plain text in the URL, we'll send it encrypted by a secret passphrase. (I know the attacker could still intercept the e-mail sent by the server, since e-mail are plain text, but bear with me here.) If an attacker then signs up with multiple free e-mail accounts and sees multiple URLs, each with the corresponding encrypted e-mail address, could the attacker more easily determine the passphrase used for encryption? Alternative Solution I could instead send a random number or one-way hash of their e-mail address (plus random salt). This eliminates storing the secret passphrase, but it means I need to store that random number/hash in the database. The original approach above does not require storage in the database. I'm leaning towards the the one-way-hash-stored-in-the-db, but I still would like to know the answer: does having multiple unencrypted e-mail addresses and their encrypted counterparts make it easier to determine the passphrase used?

  • How to properly use CoreData validation & error framework ?

    - by Xav
    I've created a model in Xcode, and for various attributes I have minimum & maximum values defined and that are enforced by coreData at runtime. I'm using NSManagedObject validateValue:forKey:error to check for user input values. I was a bit disappointed to see that the localized error message is not specific, and I get a "The operation couldn't be completed. (Cocoa error 1620)" for too small values and a "The operation couldn't be completed. (Cocoa error 1610)" for too large values. It's written in the coreData documentation that "you can localize most aspects of a managed object model, including entity and property names and error messages". Unfortunately it's not very detailed on how you implement it for error messages. So How do you customize error message ? How do you localize them ? Is it possible to customize it in a way where it will mentioned the reference value ex: "Value should be lower than %@" or "Value should be higher than %@" ?

  • unicode data with custom font doesn't work properly in ipad

    - by David Ohanyan
    I am using custom font for label and string which I am getting from unicode characters. And the font is not changing. here is the snippet of my code: NSString* str = @"\u05D0\u05D1\u05D2"; [mMatchingLabel setText:str]; mMatchingLabel.font = [UIFont fontWithName:@"David New Hebrew" size:26]; But when I write for example : NSString* str = @"label"; [mMatchingLabel setText:str]; mMatchingLabel.font = [UIFont fontWithName:@"David New Hebrew" size:26]; The font effect is evident. Can someone explain what's here wrong?

  • Free country/city suggestion list/database

    - by Ilian Iliev
    I'm looking for something similar to facebook suggestion list with cities and countries. You can see what I'm exactly talking about when you try to create new event in facebook, click to add address, and then start typing in the City field. I prefer finding working suggestion tool in jQuery(with the date), but database with city/country will do the trick too. Thanks in advance, Ilian Iliew

  • Visual Studio ReportViewer repeating data block on every page

    - by muhan
    I am using Reportviewer to generate a sales invoice to be printed by the user. How can I get databound fields to be printed on every page of a multi page invoice? The invoice is printed on a pre-printed form. I want the printed form to look roughly like: page 1 customer john smith 123 main st. city, CA 90000 some item1 $100 some item2 $150 some item3 $150 page 2 customer john smith 123 main st. city, CA 90000 some item4 $500 some item5 $250 some item6 $950 Total $2100 Using 1 list which contains databound textbox fields for the customer info, and a table for the items. The problem is if there are many items such that the items flow over to page 2, the next page only contains items, and not the customer info which needs to be printed on second page as well. I tried using page header, but I can't use databound items in page header. Please Help!

  • Neural Network: Handling unavailable inputs (missing or incomplete data)

    - by Mike
    Hopefully the last NN question you'll get from me this weekend, but here goes :) Is there a way to handle an input that you "don't always know"... so it doesn't affect the weightings somehow? Soo... if I ask someone if they are male or female and they would not like to answer, is there a way to disregard this input? Perhaps by placing it squarely in the centre? (assuming 1,0 inputs at 0.5?) Thanks

  • Read data from a text file using Java

    - by Saran
    I need to read a text file line by line using Java. I use available() method of FileInputStream to check and loop over the file. But while reading, the loop terminates after the line before the last one. i.e., if the file has 10lines, the loop reads only the first 9 lines. Snippet used : while(fis.available() > 0) { char c = (char)fis.read(); ..... ..... }

  • Aggregate Functions on subsets of data based on current row values with SQL

    - by aasukisuki
    Hopefully that title makes sense... Let's say I have an employee table: ID | Name | Title | Salary ---------------------------- 1 | Bob | Manager | 15285 2 | Joe | Worker | 10250 3 | Al | Worker | 11050 4 | Paul | Manager | 16025 5 | John | Worker | 10450 What I'd like to do is write a query that will give me the above table, along with an averaged salary column, based on the employee title: ID | Name | Title | Salary | Pos Avg -------------------------------------- 1 | Bob | Manager | 15285 | 15655 2 | Joe | Worker | 10250 | 10583 3 | Al | Worker | 11050 | 10583 4 | Paul | Manager | 16025 | 15655 5 | John | Worker | 10450 | 10583 I've tried doing this with a sub-query along the lines of: Select *, (select Avg(e2.salary) from employee e2 where e2.title = e.title) from employee e But I've come to realize that the sub-query is executed first, and has no knowledge of the table alias'd e I'm sure I'm missing something REALLY obvious here, can anyone point me in the right diretion?

  • Mapping class properties to generic columns in table .NET

    - by Tony_Henrich
    I have have a SQL Server table which has generic names like Text1, Text2.. etc. The table was designed like this because the same structure is used for different projects. I have a class in .NET which has properties. Say a Customer class has a property called FirstName. How can I do the mapping from FirstName to Text1 just once (central place) in the application so that I don't have to remember and hard code the mappings all over the app when I create the different DAL methods? For example, I want the app to know when I want to update, insert a FirstName, the DAL automatically uses Text1. Basically I don't have to remember which property goes to which column. The idea is so the developers do not map the properlies/columns in a wrong way. It's always consistent. Note: Database inserts, updates and deletes are allowed through stored procedures only.

  • Opposite of Bloom filter?

    - by abc
    Hi, I'm trying to optimize a piece of software which is basically running millions of tests. These tests are generated in such a way that there can be some repetitions. Of course, I don't want to spend time running tests which I already ran if I can avoid it efficiently. So, I'm thinking about using a Bloom filter to store the tests which have been already ran. However, the Bloom filter errs on the unsafe side for me. It gives false positives. That is, it may report that I've ran a test which I haven't. Although this could be acceptable in the scenario I'm working on, I was wondering if there's an equivalent to a Bloom filter, but erring on the opposite side, that is, only giving false negatives. I've skimmed through the literature without any luck.

  • Storing expression references to data base

    - by Marcus
    I have standard arithmetic expressions sotred as strings eg. "WIDTH * 2 + HEIGHT * 2" In this example WIDTH and HEIGHT references other objects in my system and the literals WIDTH and HEIGHT refers to a property (Name) on those objects. The problem I'm having is when the Name property on an expression object changes the expression won't match anymore. One solution I came up with is to instead of storing "WIDTH * 2 + HEIGHT * 2" i store "{ID_OF_WIDTH} * 2 + {ID_OF_HEIGHT} * 2" And let my parser be able to parse this new syntax and implement an interface or such on referenced objects IExpressionReference { string IdentifierName { get; } } Anyone have a better/alternative solution to my problem?

  • What is the point in using a "real" database modeling tool?

    - by cdeszaq
    We currently have a 10 year old nasty, spaghetti-code-style SQL Server database that we are soon looking to pretty much re-write from scratch as part of a re-write to a large web application. (The existing application will serve as the functional requirements for the next incarnation of the app). Some have suggested we use Visio to do all the diagramming and to generate the DDL, but others have suggested we use a dedicated database design tool, rather than a diagramming tool that is able to export DDL. Is there any benefit to using "real" DB design tools, such as ModelRight, over general tools like Visio? If so, what are those specific benefits? Edit: In a nutshell, what can real/dedicated tools do that something like Visio can't, and how much do these capabilities matter (from a best-practices standpoint, for example)
