  • Shell loops using non-integers?

    - by mary
    I wrote a .sh file to compile and run a few programs for a homework assignment. I have a "for" loop in the script, but it won't work unless I use only integers: #!/bin/bash for (( i=10; i<=100000; i+=100)) do ./hw3_2_2 $i done The variable $i is an input for the program hw3_2_2, and I have non-integer values I'd like to use. How could I loop through running the code with a list of decimal numbers?

  • machine learning and code generator from strings

    - by BCS
    The problem: Given a set of hand categorized strings (or a set of ordered vectors of strings) generate a decision function to categorize more input. The question: are there any tools out there that will do that? I'm thinking of some kind of reasonably polished, download, install and go kind of things, as opposed to to some library or a brittle academic program.

  • How do I protect my website from javascript injection attacks when using rich text editors?

    - by VJ
    Hi all I am using the markitup editor to get the value for one of my fields and storing it a sql server 2008 db. Now I guess the problem is people having script tags and javascript in the editor and injecting malicious scripts and I have my validate input turned false. So can anyone suggest me a way to write a custom validation method that maybe checks for script tags and removes them...or just guide me through the steps i need to do ?...also are there other things also that I should be worried about..?

  • hexdump confusion

    - by zedoo
    I am playing with the unix hexdump utility. My input file is UTF-8 encoded, containing a single character ñ, which is C3 B1 in hexadecimal UTF-8. hexdump test.txt 0000000 b1c3 0000002 Huh? This shows B1 C3 - the inverse of what I expected! Can someone explain? For getting the expected output I do: hexdump -C test.txt 00000000 c3 b1 |..| 00000002 I was thinking I understand encoding systems..

  • Mock Object and Interface

    - by tunl
    I'm a newbie in Unit Test with Mock Object. I use EasyMock. I try to understand this example: import java.io.IOException; public interface ExchangeRate { double getRate(String inputCurrency, String outputCurrency) throws IOException; } import java.io.IOException; public class Currency { private String units; private long amount; private int cents; public Currency(double amount, String code) { this.units = code; setAmount(amount); } private void setAmount(double amount) { this.amount = new Double(amount).longValue(); this.cents = (int) ((amount * 100.0) % 100); } public Currency toEuros(ExchangeRate converter) { if ("EUR".equals(units)) return this; else { double input = amount + cents/100.0; double rate; try { rate = converter.getRate(units, "EUR"); double output = input * rate; return new Currency(output, "EUR"); } catch (IOException ex) { return null; } } } public boolean equals(Object o) { if (o instanceof Currency) { Currency other = (Currency) o; return this.units.equals(other.units) && this.amount == other.amount && this.cents == other.cents; } return false; } public String toString() { return amount + "." + Math.abs(cents) + " " + units; } } import junit.framework.TestCase; import org.easymock.EasyMock; import java.io.IOException; public class CurrencyTest extends TestCase { public void testToEuros() throws IOException { Currency testObject = new Currency(2.50, "USD"); Currency expected = new Currency(3.75, "EUR"); ExchangeRate mock = EasyMock.createMock(ExchangeRate.class); EasyMock.expect(mock.getRate("USD", "EUR")).andReturn(1.5); EasyMock.replay(mock); Currency actual = testObject.toEuros(mock); assertEquals(expected, actual); } } So, i wonder how to Currency use ExchangeRate in toEuros(..) method. rate = converter.getRate(units, "EUR"); The behavior of getRate(..) method is not specified because ExchangeRate is an interface.

  • Looping through all attributes of a XML element in XSLT

    - by TheGNUGuy
    Hey everyone, I am trying to use <xsl:for-each select="@*"> to grab all the attributes of a given element but when i do that my <xsl:choose> statement doesn't execute. Here is the element that I'm working with: <textBox id="Airfare" value="" label="text 1"/> Here is the XSLT template I'm using: <xsl:template match="textBox"> <div> <xsl:choose> <xsl:when test="@label"> <xsl:value-of select="@label"/> </xsl:when> <xsl:otherwise> <xsl:text>No Label Defined</xsl:text> </xsl:otherwise> </xsl:choose> <xsl:element name="input"> <xsl:attribute name="type">text</xsl:attribute> <xsl:for-each select="@*"> <xsl:choose> <xsl:when test="@id"> <xsl:attribute name="name">form_<xsl:value-of select="@id"/></xsl:attribute> <xsl:attribute name="id">form_<xsl:value-of select="@id"/></xsl:attribute> </xsl:when> <xsl:when test="@label"> </xsl:when> <xsl:otherwise> <xsl:copy-of select="current()"/> </xsl:otherwise> </xsl:choose> </xsl:for-each> </xsl:element> </div> And when I generate the HTML using PHP I get this: <div>text 1<input type="text" id="Airfare" value="" label="text 1"></div> As you can see it didn't add form_ to the id attribute it didn't generate a name attribute and it didn't skip over the label attribute. Thanks for your help!

  • Web application starter kit

    - by Steve Robillard
    I am looking for a site that allows you to input a project name, choose a doctype, a js library etc. and then generates the directory structure and files to start a web project. I know about project deploy, but it is no longer maintained. There was a new one that was created within the last 2 or 3 months, but for the life of me I can't find it either through Google nor my delicious bookmarks. Any help would be greatly appreciated. Thanks, Steve

  • Django admin breaking with non-default primary_key for model with a m2m relationship ?

    - by Gj
    I have a simple Post model with a m2m field to a Tag model. The Tag had for some reason to use a non default primary key. Inside the admin page for a Post, the labels for the multiple selection field for Tags appear, but not the input field itself. I also tried using the filter_horizontal for the tags, but still only the labels appear without the actual field. Any ideas why it breaks and/or workarounds? Thanks!

    - by SimonNet

So as I enter it becomes, P -- *a -- **s etc.. How is this done? I presume its javascript? If somone can point me in the right direction that would be great.

  • How to make a text box in a command line window?

    - by The.Anti.9
    I'm working with .NET (specifically Boo, but answers would work in C# too) and I want to know how I could create an editable box inside the command line, such that I could display a section of output in the top part of the command line, and have a one line box at the bottom for input, much like the program irssi (the IRC client) does. I assume this is possible with .NET, how would I approach this?

  • Automatically open files given as command line arguments in Python

    - by mk
    I have a lot of Perl scripts that looks something like the following. What it does is that it will automatically open any file given as a command line argument and in this case print the content of that file. If no file is given it will instead read from standard input. while ( <> ) { print $_; } Is there a way to do something similar in Python without having to explicitly open each file?

  • Linq Aggregate function

    - by Nyla Pareska
    I have a List like "test", "bla", "something", "else" But when I use the Aggrate on it and in the mean time call a function it seems to me that after 2 'iterations' the result of the first gets passed in? I am using it like : myList.Aggregate((current, next) => someMethod(current) + ", "+ someMethod(next)); and while I put a breakpoint in the someMethod function where some transformation on the information in the myList occurs, I notice that after the 3rd call I get a result from a former transformation as input paramter.
