  • Parsec Haskell to HTML

    - by Martin
    I'm using Text.ParserCombinators.Parsec and Text.XHtml to parse an input like this: hello 123 --this is an emphasized text-- bye\n And my output should be: <p>hello 123 <em>this is an emphasized text</em> bye\n</p> Any ideas? Thanks!!

  • 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..

  • 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?

  • 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.

  • Java app makes screen display unresponsive after 10 minutes of user idle time

    - by Ross
    I've written a Java app that allows users to script mouse/keyboard input (JMacro, link not important, only for the curious). I personally use the application to automate character actions in an online game overnight while I sleep. Unfortunately, I keep coming back to the computer in the morning to find it unresponsive. Upon further testing, I'm finding that my application causes the computer to become unresponsive after about 10 minutes of user idle time (even if the application itself it simulating user activity). I can't seem to pin-point the issue, so I'm hoping somebody else might have a suggestion of where to look or what might be causing the issue. The relevant symptoms and characteristics: Unresponsiveness occurs after user is idle for 10 minutes User can still move the mouse pointer around the screen Everything but the mouse appears frozen... mouse clicks have no effect and no applications update their displays, including the Windows 7 desktop I left the task manager up along the with the app overnight so I could see the last task manager image before the screen freezes... the Java app is at normal CPU/Memory usage and total CPU usage is only ~1% After moving the mouse (in other words, the user comes back from being idle), the screen image starts updating again within 30 minutes (this is very hit and miss... sometimes 10 minutes, sometimes no results after two hours) User can CTRL-ALT-DEL to get to Windows 7's CTRL-ALT-DEL screen (after a 30 second pause). User is still able to move mouse pointer, but clicking any of the button options causes the screen to appear to freeze again On some very rare occasions, the system never freezes, and I come back to it in the morning with full responsiveness The Java app automatically stops input scripting in the middle of the night, so Windows 7 detects "real" idleness and turns the monitors into Standby mode... which they successfully come out of upon manually moving the mouse in the morning when I wake up, even though the desktop display still appears frozen Given the symptoms and characteristics of the issue, it's as if the Java app is causing the desktop display of the logged in user to stop updating, including any running applications. Programming concepts and Java packages used: Multi-threading Standard out and err are rerouted to a javax.swing.JTextArea The application uses a Swing GUI awt.Robot (very heavily used) awt.PointerInfo awt.MouseInfo System Specs: Windows 7 Professional Java 1.6.0 u17 In conclusion, I should stress that I'm not looking for any specific solutions, as I'm not asking a very specific question. I'm just wondering if anybody has run into a similar problem when using the Java libraries that I'm using. I would also gladly appreciate any suggestions for things to try to attempt to further pinpoint what is causing my problem. Thanks! Ross PS, I'll post an update/answer if I manage to stumble across anything else while I continue to debug this.

  • 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..?

  • 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?

  • How do I create a simple seach box with a submit button to bring back a result set in MVC?

    - by RJ
    I am very new to MVC and just learning the basics. I have been following along in Nerd Dinner and used the demo as a way to create my own app. I have created a page that lists out some food items with calories, fat, protein,etc... (http://rjsfitness.net/CalorieList) This is one of my own personal sites that I set up to test out MVC. I got a lot of it working but I am stuck on the textbox with a search button. My view page has this code for the search: <form action="/CalorieList/Search" method="post" id="searchForm"> <input type="text" name="searchTerm" id="searchTerm" value="" size="10" maxlength ="30" /> <input type ="submit" value="Search" /> </form> My global.asax has this code for the routing: routes.MapRoute( "Search", // Route name "CalorieList/Search/{searchTerm}", // URL with parameters new { controller = "CalorieList", action = "Search", search = "" } // Parameter defaults ); My Controller has this code: public ActionResult Index(int? page) { const int pageSize = 10; //load a list with the calorie list var calorieLists = calorieListRepository.GetAllCalorieLists(); //var paginatedCalorieLists = calorieLists.Skip((page ?? 0) * pageSize).Take(pageSize).ToList(); var paginatedCalorieLists = new PaginatedList<CalorieList>(calorieLists, page ?? 0, pageSize); return View("Index", paginatedCalorieLists); } public ActionResult Search(String searchTerm) { const int pageSize = 100; int? page = 0; var calorieLists = calorieListRepository.GetCalorieListsBySearch(searchTerm); var paginatedCalorieLists = new PaginatedList<CalorieList>(calorieLists, page ?? 0, pageSize); return View("Index", paginatedCalorieLists); } return View("Index", paginatedCalorieLists); } When I enter a value and click the button, the Index method fires instead of the Seach method in the controller and I get the full list again. If I manually type the url (http://rjsfitness.net/CalorieList/Search/choc) I get the right listing. Why isn't my button click using the right routing and giving me the search results?

  • 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.

  • How to disable html button using JavaScript?

    - by Jack Roscoe
    Hi, I've read that you can disable (make physically unclickable) a html button simply but appending 'disable' to its tag, but not as an attribute, as follows: <input type="button" name=myButton value="disable" disabled> Since this setting is not an attribute, how can I add this in dynamically via JavaScript to disable a button that was previously enabled?

  • How can I securely check if a username is already taken?

    - by Geo
    I have a form where someone can create a new user. I'd like to add some AJAX to check if a username is taken, as soon as the input field loses focus. I'm not really sure how to go about this, as this could pave the way to bruteforce attack, since you could check for any username and see whether or not it exists. Any suggestions?

  • 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.
