  • How do I read from a file consists of city names and coordinates/Populations and create functions to get the coordinates and population?

    - by Braybray
    I'm using Python, and I have a file which has city names and information such as names, coordinates of the city and population of the city: Youngstown, OH[4110,8065]115436 Yankton, SD[4288,9739]12011 966 Yakima, WA[4660,12051]49826 1513 2410 Worcester, MA[4227,7180]161799 2964 1520 604 Wisconsin Dells, WI[4363,8977]2521 1149 1817 481 595 How can I create a function to take the city name and return a list containing the latitude and longitude of the given city? fin = open ("miles.dat","r") def getCoordinates cities = [] for line in fin: cities.append(line.rstrip()) for word in line: print line.split() That's what I tried now; how could I get the coordinates of the city by calling the names of the city and how can I return the word of each line but not letters? Any help will be much appreciated, thanks all.

  • What is the purpose of OCaml's Lazy.lazy_from_val?

    - by Ricardo
    The doc of Lazy.lazy_from_val states that this function is for special cases: val lazy_from_val : 'a -> 'a t lazy_from_val v returns an already-forced suspension of v This is for special purposes only and should not be confused with lazy (v). Which cases are they talking about? If I create a pair of suspended computation from a value like: let l1 = lazy 123 let l2 = Lazy.lazy_from_val 123 What is the difference between these two? Because Lazy.lazy_is_val l1 and Lazy.lazy_is_val l2 both return true saying that the value is already forced!

  • Making a jQuery plugin work on all objects

    - by Jon Winstanley
    I am using the jQuery physics plugin for a pet project I am working on. The plugin enables the moving of DOM objects in realistic ways using velocity, gravity, wind etc. However I want to use the plugin to calculate where objects are to be placed inside a canvas element, not DOM objects. How do I change the plugin script functions to work on any object with 'top' and 'left' properties rather than only working with DOM objects: Currently the script functions look like this: jQuery.fn.funname = function() { return this; };

  • How do I write a scheme macro that defines a variable and also gets the name of that variable as a s

    - by Jason Baker
    This is mostly a follow-up to this question. I decided to just keep YAGNI in mind and created a global variable (libpython). I set it to #f initially, then set! it when init is called. I added a function that should handle checking if that value has been initialized: (define (get-cpyfunc name type) (lambda args (if libpython (apply (get-ffi-obj name libpython type) args) (error "Call init before using any Python C functions")))) So now here's what I want to do. I want to define a macro that will take the following: (define-cpyfunc Py_Initialize (_fun -> _void)) And convert it into this: (define Py_Initialize (get-cpyfunc "Py_Initialize" (_fun -> _void))) I've been reading through the macro documentation to try figuring this out, but I can't seem to figure out a way to make it work. Can anyone help me with this (or at least give me a general idea of what the macro would look like)? Or is there a way to do this without macros?

  • Applying styles for custom TextArea in ActionScript 3

    - by Vijay Dev
    I have the following code to create and apply a few styles for a custom TextArea in ActionScript 3. public class MyCustomTextArea extends TextArea { override protected function createChildren():void { super.createChildren(); this.styleSheet.setStyle("sup", { display: "inline", fontFamily: "ArialSup", fontSize:"12"}); this.styleSheet.setStyle("sub", { display: "inline", fontFamily: "ArialSub", fontSize:"12"}); this.setStyle("fontFamily", "Arial"); } } I have two problems with this code. this.styleSheet is always null when I create an instance of the class. If this.styleSheet is initialized to new StyleSheet() to avoid this issue, then the TextArea instance does not seem to recognize any of the HTML tags that can be used with the htmlText property. Can anyone help in fixing these two issues? Thanks.

  • System.Diagnostics.Debugger.Debug() stopped working

    - by Andrew Miner
    I'm working on a program which uses the System.Diagnostics.Debugger.Break() method to allow the user to set a breakpoint from the command-line. This has worked fine for many weeks now. However, when I was working on fixing a unit test today, I tried to use the debug switch from the command-line, and it didn't work. Here's what I've tried: I've confirmed that the Debug() method is really being called (by putting a System.Console.WriteLine() after it) I've confirmed that the build is still in Debug I've done a clean build I've restarted Product Studio A quick Google search didn't reveal anything, and the API documentation for .Net doesn't mention anything about this function not performing correctly. So... any ideas?

  • jQuery selector question

    I have a span and an anchor inside a table cell. I have the anchor set up to show a tooltip. I would like the text inside the span to be used for the tooltip.

  • GMap in iframe gets off-center

    - by Daj pan spokój
    I have a Google Map (API 2) that used to work fine as a standalone page. However, when I load the map page within an iframe (with Thickbox), the map gets off-center: normally it's centered over Germany and in the iframe it centers on Iran, instead. How to make the map center correctly? My guesses: The problem can result from the iframe loading time. I guess, that the script calculates window size basing on the iframe size when it's still loading. It's strange since I load the map when the document is ready. $(document).ready(function() { setupSearchForm(); setupMap(); setupResults(); }); For instance, when I refresh the already loaded iframe the center comes back to Germany. A sample of code loading the map

  • customisable JSLint

    - by Don
    Hi, I'm looking for a tool that checks JS code, which can be integrated into a Maven build. I need a tool that will check for errors such as use of reserved words as identifiers trailing semi-colon, e.g. var obj = { a: 1, b, 2, } JSLint seems like a perfect candidate, but the problem is that it is too strict, because it also checks for various coding patterns which are (arguably) bad style, but do not actually generate errors in a browser. Examples of such issues include Disallow ++ and -- and Allow one var statement per function If possible, I would like the errors to fail the build, and I would like the other rules to only print warnings (or disable them completely). Obviously, I need the ability to specify which of the available rules I consider errors and which I consider warnings. Thanks, Don

    Can anyone help me with this major issue I have. I have downloaded my Drupal 7 site running fine on current server, but I cant run it on localhost or on the new server where I am trying to move it... It just gives me the "White Screen of Death"... and after commenting "set_error_handler" in boostrap.inc, I find out that the errors are all related to "public://" wrapper. This is how all the errors look like: Warning: is_dir() [function.is-dir]: Unable to find the wrapper "public" - did you forget to enable it when you configured PHP All these errors are coming from the following file: /includes/file.inc

  • JSP 2.0 SEO friendly links encoding

    - by victor hugo
    Currently I have something like this in my JSP <c:url value="/teams/${contact.id}/${contact.name}" /> The important part of my URL is the ID, I just put the name on it for SEO purposes (just like stackoverflow.com does). I was just wondering if there is a quick and clean way to encode the name (change spaces per +, latin chars removal, etc). I'd like it to be like this: <c:url value="/teams/${contact.id}/${supercool(contact.name)}" /> Is there a function like that out there or should I make my own?

  • C++ word to bytes

    - by Vit
    Hi, I tried to read CPUID using assembler in C++. I know there is function for it in , but I want the asm way. So, after CPUID is executed, it should fill eax,ebx,ecx registers with ASCII coded string. But my problem is, since I can in asm adress only full, or half eax register, how to break that 32 bits into 4 bytes. I used this: #include <iostream> #include <stdlib.h> int main() { _asm { cpuid /*There I need to mov values from eax,ebx and ecx to some propriate variables*/ } system("PAUSE"); return(0); }

  • Dashcode Web App: How to programmatically manipulate bound array in dataSource?

    - by Kross
    Hi Everyone, I've started using Dashcode to write an interface for presenting the report data for some of our Cocoa tools. I am using a Dashcode data source and bindings to populate the elements in the WebView, and it all seems to be working well so far. One of the objects in my dataSource is an array of objects that I would like to manipulate programmatically. I can change the object values in the array just fine but if I want to replace the array, or any objects in the array, my bound table isn't able to observe the added objects. Here is the code that I thought would let me easily replace the bound array with new content: var dataSource = dashcode.getDataSource("reportData"); var newDetailArray = testArray(); dataSource.setValueForKeyPath(newDetailArray, "content.detailArray"); But this throws the exception: Exception while binding "content" to keypath "arrangedObjects " TypeError: Result of expression 'this.object.valueForKeyPath' [undefined] is not a function. Is there something I'm missing that will let me easily manipulate the array's contents programmatically?

  • Why doesn't this work?

    - by user146780
    I'v tried to solve a memory leak in the GLU callback by creating a global variable but now it dos not draw anything: GLdouble *gluptr = NULL; void CALLBACK combineCallback(GLdouble coords[3], GLdouble *vertex_data[4], GLfloat weight[4], GLdouble **dataOut) { GLdouble *vertex; if(gluptr == NULL) { gluptr = (GLdouble *) malloc(6 * sizeof(GLdouble)); } vertex = (GLdouble*)gluptr; vertex[0] = coords[0]; vertex[1] = coords[1]; vertex[2] = coords[2]; for (int i = 3; i < 6; i++) { vertex[i] = weight[0] * vertex_data[0][i] + weight[1] * vertex_data[0][i] + weight[2] * vertex_data[0][i] + weight[3] * vertex_data[0][i]; } *dataOut = vertex; } basically instead of doing malloc each time in the loop (thus the memory leak) im using a global pointer, but this doesn't work (drawing to the screen). Why would using malloc to a pointer created in the function work any different than a global variable? Thanks

  • MySQL: Get only count of result set.

    - by Varun
    I am using MVC with PHP/MySQL. Suppose I am using 10 functions with different queries for fetching details from the database. But at other times I may want to get only the count of the result that will be returned by the query. What is the standard way to handle such situation. Should I write 10 more functions which duplicate almost whole query and return only the count. Or Should I always return the count also with the result set Or I can pass a flag to indicate that the function should return count only, and then based on the flag I will dynamically generate the (select part of) query. Or Is there a better way?

  • create a folder and files in c:\program files\myApp\data in windows 7

    - by ile
    I have an old c++ application that needs to be modified to work with windows 7. Problem is in creating a new folder and saving a file in that folder. This folder should be created in c:\program files\myApp\data\newFolder. This is function I use to create new folder and get errors: if(!CreateDirectory(pathSamples,NULL)) //Throw Error { DWORD errorcode = GetLastError(); LPVOID lpMsgBuf; FormatMessage(FORMAT_MESSAGE_ALLOCATE_BUFFER | FORMAT_MESSAGE_FROM_SYSTEM | FORMAT_MESSAGE_IGNORE_INSERTS, NULL, errorcode, MAKELANGID(LANG_NEUTRAL, SUBLANG_DEFAULT), (LPTSTR)&lpMsgBuf, 0, NULL ); MessageBox(NULL, (LPCTSTR)lpMsgBuf, TEXT("Error"), MB_OK); } In XP this works, but in Windows 7 it doesn't. If I run application as administrator than the folder is created, otherwise "Access is denied" error is thrown. My question is following: Is there an option to make changes to the code so that the folder can be created in "program files" nad that files can be saved in this folder? PS I saw this thread already but it doesn't answer my question. Thanks, Ilija

But once the form is placed in an iframe, the cancel function does not work. Can you please help? Here is the code: public class Cancell extends com.ford.forms.types.Button { /** * Cancel constructor comment. */ public Cancell() { setImageName("../images/cancel.png"); setOnClickScript("if (confirm('This selection will clear your entries and close this form.

  • Passing dependent objects to a parent constructor in Scala

    - by Nick Johnson
    Suppose I have the following class heirarchy: class A() class B(a:A) class C(b:B) class BaseClass(b:B, c:C) Now I want to implement a subclass of BaseClass, which is given an instance of A, and constructs instances of B and C, which it passes to its superclass constructor. If I could use arbitrary expressions, I'd do something like this: b = new B(a) c = new C(b) super(b, c) Because the second argument to the parent constructor depends on the value of the first argument, though, I can't see any way to do this, without using a factory function, or a gratuitous hack, such as : class IntermediateSubclass(b:B) extends BaseClass(b, new C(b)) class RealSubclass(a:A) extends IntermediateSubclass(new B(a)) Is there clean way to do this?
