What's the Pythonic way to loop through an iterator when the first few values are special?
|
<p>The standard away is:</p>
<pre><code>it = iter(sequence)
for value in it:
print value
</code></pre>
<p>I'm using a third party library that returns an iterator with the first value being a header, the second value being metadata and the rest of the values being records. I have tried something like:</p>
<pre><code>db = dbfreader(f)
headers = db.next()
spec = db.next()
record = db.next()
while record:
print record
record = db.next()
</code></pre>
<p>But that results in a StopIteration error</p>

C# Abstract class clarification
|
<p>As abstract class can not be initialized,why the constructors are allowed?</p>
<p>I thought ,Incase i need to pass information to base class (abstract class in this class),i need to have constructor. I .. mean</p>
<pre><code> abstract class Person
{
string regNo,name;
public Person(string regNo,string name)
{
this.regNo = regNo;
this.name = name;
}
public string RegNo
{
get { return regNo; }
}
public string Name
{
get { return name; }
}
}
class student : Person
{
student(string regno, string name)
: base(regno, name)
{
}
}
</code></pre>
<p>is this the purpose the constructor is allowed inside abstract class?</p>

Having trouble writing XML in Python
|
<p>I have a XML file that I read with Python. I want to make some changes in the XML file and write it back out.</p>
<p>Here is my code:</p>
<pre><code>from xml.dom.minidom import *
filename = "file.xml"
dom = xml.dom.minidom.parse(filename)
dicts = dom.getElementsByTagName("dict")
for dict in dictList:
keys = dict.getElementsByTagName("key")
for key in keys:
keyCData = key.firstChild.wholeText
if keyCData == "kind":
print keyCData #prints "kind"
key.firstChild.wholeText = "new text"
print key.firstChild.wholeText #prints "new text"
f = open("temp.xml", 'w')
dom.writexml(f)
f.close()
</code></pre>
<p>When I open "temp.xml" to look at though, all my elements with the "key" tag still have their CData as "kind" instead of "new text". So how do I get the new data to be written out to the file?</p>

Static analysis of Python code, in a codebase that includes multiple implementations of the same module all having the same interface
|
<p>I don't miss having to type out type declarations all the time - that's one of many reasons I love python.</p>
<p>But I like to at least have some "variable used before set", "variable set but never used" and "wrong number of arguments" checks, to avoid trivial errors.</p>
<p>pylint is reportedly the most stringent static analysis tool for Python, so I've been using it to get such checks.</p>
<p>However, I have a bit of a disappointment with pylint: EG, I have 3 modules that do compression in 3 different ways (subprocess, ctypes, bz2 module), and I want to add a 4th (the new lzma module in CPython 3.3, which hasn't yet been released). These modules all have slightly different portability and behavior. I want pylint to be able to check these alternatives, but it seems to get lost.</p>
<p>So I started using a tiny "dispatch module" for a while, that would do nothing but choose between the different compression alternatives, and that Wouldn't Be Pylint'd, and that sort of works, but not as well as I'd like. It allows me to pylint most of my code, but it seems to make pylint unable to check uses of the compression code.</p>
<p>Is there some way of getting static analysis for python that allows the checking of multiple modules all providing the same interface, as well as calls into those modules from the same code? Maybe pyflakes? Or a magic "# pylint:" hint I don't don't know about?</p>
<p>Thanks!</p>

How To Modify This Array Into Associative Array?

<pre><code><option selected value='M'>Male</option>
<option value='F'>Female</option>

<pre><code>$genders = array('M'=>'Male', 'F'=>'Female');
</code></pre>
<p>but how to get array's index so it can be used as value on the option tag?</p>

Specifying startup window/form location on multiple displays
|
<p>I have two displays (two monitors) connected to my machine, and I noticed a strange thing happening today. I had an Explorer window open with my compiled exe on my primary display, and when I double-clicked it, it opened in the primary display (left monitor). However if I pressed enter to launch the executable, it started in the secondary display (right monitor). The window state of the initial form is maximized. Is there a way to tell C# to open the initial form in the primary display?</p>

Calling a new activity when threads running - IllegalThreadStateException
|
<p>I am developing a game which so far has involved just two activities: a splash screen and a main activity. The main activity starts up a new thread which handles the drawing and game mechanics. So far the game has been working nicely. Now I have just added a new button for the purposes of viewing a "high scores" page in a new activity. So I set up an onClick handler and when the button is clicked I call the following code:</p>
<pre><code>in = new Intent("android.intent.action.HIGH");
startActivity(in);
</code></pre>
<p>and in the high scores activity I have an [Ok] button which instigates the following:</p>
<pre><code>back_but.setOnClickListener(new OnClickListener()
{
public void onClick(View arg0)
{
finish();
}
});
</code></pre>
<p>When I click the button to view the high scores, the high scores activity starts up fine, unfortunately when I click the [Ok] button the program crashes with an IllegalThreadStateException.</p>
<p>Should I have stopped or paused the game thread in the main program before calling the new activity?</p>

Structuring an iPhone app with several views
|
<p>I am confused by the relationship between the appDelegate, MainWindow and the various views (and corresponding contollers). What I want to achieve is to immediately after app launch, hand control over to a "mainController" class that in turn loads the nib-files as needed (to minimize program logic in the app delegate). First, I need to load a login screen, and after successful login the application content, whose logic I have read ideally should reside outside the appDelegate, hence the "mainController" class.</p>
<p>Does the "mainController" need to be connected with a (blank) nib-file? Should this mainController subclass the UIViewController class albeit it holds no GUI contents on itself and be instanciated with [window addSubview:mainViewController.view]; [window makeKeyAndVisible]; ? Or should I use the alloc/init syntax. In which case, how do I reference the window from the (sub)views in order to add views programmatically?</p>
<p>Any hints, tips or tutorials would be helpful.</p>

Fill out javascript with python?

<p>I am trying to parse an html page but I need to filter the results before I parse the page.</p>
<p>For instance, 'http://www.ksl.com/index.php?nid=443' is a classified listing of cars in Utah. Instead of parsing ALL the cars, I'd like to filter it first (ie find all BMWs) and then only parse those pages. Is it possible to fill in a javascript form with python?</p>
<p>Here's what I have so far:</p>
<pre><code>import urllib
content = urllib.urlopen('http://www.ksl.com/index.php?nid=443').read()
f = open('/var/www/bmw.html',"w")
f.write(content)
f.close()

</code></pre>
<p>When I click my galleryButtonLeft to move it <code>300px</code> to the left, the page immediately goes to the top if I have my browser unmaximized and scroll to the middle of the page where my gallery sits. I want the page to stay where it is and not jump to the top everytime the button is clicked. How do I do that?</p>

Installation error: INSTALL_PARSE_FAILED_NO_CERTIFICATES
|
<p>At the risk of repeating what appears to be a very common complaint, I think I have a substantial variation on this bug.</p>
<p>The application won't install from Eclipse and this appears in the console: Installation error: INSTALL_PARSE_FAILED_NO_CERTIFICATES.</p>
<p>LogCat provides some illumination: Package com.xxx has no certificates at entry assets/fonts/helvetica_neue.ttf; ignoring!</p>
<p>Meaning that the device (or emulator) believes that this particular file wasn't signed.</p>
<p>The usual solutions proposed for this are:<br/>
- Rename the offending file. We've tried that, it then complains about the next file, then the next, and so on.<br/>
- Add a dummy file. Tried that too. It complains about the new file, regardless of what it's called.<br/>
- Compile for greater than Android 1.6. We're compiling for 2.3.</p>
<p>It's worth noting this only happens when we launch a unit test. We can install the "real" application on its own with no difficulties. We're also using Maven and, of course, the Maven Android plugin.</p>
<p>Any insights or suggestions would be very welcome and of course if we figure it out on our own I'll post any findings.</p>

PHP Parse Error: syntax error, unexpected T_ENCAPSED_AND_WHITESPACE, expecting T_STRING or T_VARIABLE or T_NUM_STRING
|
<p>I've been trying to debug this for the past five minutes, I just don't get what the problem is:</p>
<p>Here's my code, lines 33 - 37:</p>
<pre><code>for($i = 0; $i < 5; $i++) {
$followers_change[$i] = $en_array1[$i]['followers']-$en_array2[$i]['followers'];
$rank_change[$i] = $en_array1[$i]['rank']-$en_array2[$i]['rank'];
echo "<tr><td>$en_array1[$i]['rank']</td><td><img src='$en_array1[$i]['imageurl']' width='48' height='48'/></td><td>$en_array1[$i]['name']</td><td>$en_array1[$i]['followers]'</td><td>$en_array1['followers_change']</td></tr>";
}
</code></pre>
<p>I keep getting the error:</p>
<blockquote>
<p>Parse error: syntax error, unexpected T_ENCAPSED_AND_WHITESPACE, expecting T_STRING or T_VARIABLE or T_NUM_STRING in /.../ on line 36</p>
</blockquote>
<p>I apologize for this being such a stupid/rookie error, I'm just stumped and tired at the same time (which doesn't make a good combination :)).</p>

Looking to pass size of files back to a directory listing
|
<p>I needed some help with passing the size of a list of files to a method and having it list the files size next to the name. For some reason I am having an issue getting this to pass through.
I have all the files assigned to a value "directory"</p>
<p>I have the files called and the method as a private String xyz(long size)</p>
<p>I have tried calling by xyz(directory), or long file = new directory.legnth then xyz(directory)....</p>
<p>I am banging my head against the wall with this any assistance appreciated.</p>
<p>EDIT 1:</p>
<p>When I say directory that is just what I am using to refer to the path of the directory to be traversed, I have one method that is recursively listing the files in a folder, and I am trying to pass a long variable to anther method to return the size of each file. So currently I get a listing of all files but thats about it. For some reason it will just not come to me as to how to get the method called.</p>

Does java(compiler or jvm) handles static final members of class differently? If yes how

<p>It seems logical to do some optimization around static final constants ( e.g. replace the variable with literals etc ) to improve the performance</p>

Strange javascript operator: expr >>> 0
|
<p>the following function is designed to implement the <code>indexOf</code> property in IE. If you've ever had to do this, I'm sure you've seen it before.</p>
<pre><code>if (!Array.prototype.indexOf){
Array.prototype.indexOf = function(elt, from){
var len = this.length >>> 0;
var from = Number(arguments[1]) || 0;
from = (from < 0)
? Math.ceil(from)
: Math.floor(from);
if (from < 0)
from += len;
for (; from < len; from++){
if (from in this &&
this[from] === elt)
return from;
}
return -1;
};
}
</code></pre>
<p>I'm wondering if it's common to use three greater than signs as the author has done in the initial length check? </p>
<p><code>var len = this.length >>> 0</code></p>
<p>Doing this in a console simply returns the length of the object I pass to it, not true or false, which left me pondering the purpose of the syntax. Is this some high-level JavaScript Ninja technique that I don't know about? If so, please enlighten me!</p>

Get a contact's groups?
|
<p>I'm trying to make a many-to-many mapping of contacts to groups.</p>
<p>For example, if I have:</p>
<ul>
<li>User 1, belongs to group 701, 702, 704</li>
<li>User 2, belongs to no groups</li>
<li>User 3, belongs to group 702</li>
</ul>
<p>I'm hoping to get a relation that looks like this:</p>
<pre><code>userID | groupID
1 | 701
1 | 702
1 | 704
3 | 702
</code></pre>
<p>I've tried this:</p>
<pre><code>Cursor cursor = contentResolver.query(ContactsContract.Data.CONTENT_URI, null, new String[] {
ContactsContract.CommonDataKinds.GroupMembership.CONTACT_ID,
ContactsContract.CommonDataKinds.GroupMembership.GROUP_SOURCE_ID
}, null, null, null);
</code></pre>
<p>But that doesn't quite work. The GROUP_SOURCE_ID column returns weird numbers that aren't the ID of any groups. Sometimes it even returns 0 or a negative number.</p>
<p>I could construct a mapping of this by going through each group, and finding all contacts in that group, but that would take a lot of queries, and I'm trying to stay fast (apparently, just those few queries are quite slow!).</p>
<p>Can anyone tell me how I can get this contacts-to-groups mapping in one query?</p>
<p>Thanks!</p>

How to invoke Application.AddMessageFilter in a Dll
|
<p>I'd like to create a dll file in C# that has a static method calling Application.AddMessageFilter() on a Win form loading this dll.</p>
<p>For example,</p>
<pre><code>public Form1()
{
// initializing
MyDll.InvokeFilter(SomeClass); // Perfect!
}
</code></pre>
<p>And I don't want it to look like as below, (I don't even think that this code would correctly work though)</p>
<pre><code>public Form1()
{
// initializing
// Send also the delegate to Application.AddMessageFilter as a parameter
// to let MyDll know it, which is not as good.
MyDll.InvokeFilterWithDelegate(SomeClass, Application.AddMessageFilter);
}
</code></pre>
<p>The thing is I don't know how to invoke Application.AddMessageFilter from my Dll file because Application class belongs to Form1, not to my Dll library.</p>
<p>What am I missing? </p>
<p>Thanks in advance.</p>

erase(remove_if()) anomaly

<p>I've created a function to run through a vector of strings and remove any strings of length 3 or less. This is a lesson in using the STL Algorithm library.</p>
<p>I'm having trouble in that the functions work but not only does it delete strings of length 3 or less but it also appends the string "vector" to the end. </p>

<p>and instead it is</p>
<pre><code>This test vector vector"
</code></pre>
<p>How can I fix it?</p>
<pre><code>/*
* using remove_if and custom call back function, write RemoveShortWords
* that accepts a vector<string> and removes all strings of length 3 or
* less from it. *shoot for 2 lines of code in functions.

Does jQuery continue filtering if it finds 0 matches?
|
<p>I have a question regarding efficiency of jQuery filtering. I've just written quite a lengthy expression and I was wondering if jQuery stops filtering if the current number of matches is 0.</p>
<pre><code>passengers.filter('input.FromDate[value="01/09/2011"]')
.closest('tr')
.filter('input.ToDate[value="08/09/2011"]')
.length;
</code></pre>
<p>If after the first <code>filter()</code> call the number of matches is 0 will jQuery continue to search the DOM or will it forego the additional calls and just return 0?</p>

Android 9-patch batch
|
<p>I am using the Android 9-patch tool to generate my 9-patch images. I have to support a number of different resolutions and button states. This means that for a single 9-patch button I need to generate 16 separate assets. Currently I am generating each of these separately using the Android 9-patch tool interface which is taking a lot of my time. If I was able to specify the 9-patch dot for a range of buttons which have the same properties this would save me a lot of time. Is there the equivalent of a command line tool or other approach which would help.</p>

Possible to assign to multiple variables from an array?
|
<p>Is it a standard way to assign to multiple variables from an array in JavaScript?
In Firefox and Opera, you can do:</p>
<pre><code>var [key, value] = "key:value".split(":");
alert(key + "=" + value); // will alert "key = value";
</code></pre>
<p>But it doesn't work in IE8 or Google Chrome.</p>
<p>Does anyone know a nice way to do this in other browsers without a tmp variable?</p>
<pre><code>var tmp = "key:value".split(":");
var key=tmp[0], value=tmp[1];
</code></pre>
<p>Is this something that will come in an upcoming JavaScript version, or just custom implementation in FF and Opera?</p>

.ashx File Downloader - Auto-Detect MIME Type
|
<p>I'm throwing together a simple file upload/download component for the navigation menu on our intranet site to give it some really basic document management functionality. It's nothing you probably haven't seen a dozen times before, but the downloader code is included below for reference. This is ASP.NET 3.5 on IIS 7.5</p>
<p>The big question is how can I have the MIME type automatically set using the IIS MIME type map for the site? I'd like to have the handler do its work getting the file content and filename from the database, then tell IIS, "Here, you figure out the MIME type, since you're so good at it."</p>
<pre><code>public void ProcessRequest(HttpContext context) {
int id = Int32.Parse(context.Request.QueryString["id"]);
string AttachmentName = null;
byte[] Attachment = null;
using (SqlConnection dbconn = new SqlConnection(WebConfigurationManager.ConnectionStrings["NavMenu"].ConnectionString)) {
dbconn.Open();
using (SqlCommand sql = new SqlCommand("NavMenu_GetFile", dbconn)) {
sql.CommandType = CommandType.StoredProcedure;
sql.Parameters.AddWithValue("@id", id);
using (SqlDataReader reader = sql.ExecuteReader()) {
if (reader.Read()) {
AttachmentName = reader["AttachmentName"] as string;
Attachment = (byte[])reader["Attachment"];
} else {
return;
}
}
}
dbconn.Close();
}
context.Response.AddHeader("Content-Disposition", String.Format("attachment;filename={0}", AttachmentName));
context.Response.BinaryWrite(Attachment);

-1 as a return value
|
<p>This question is specifically about PHP, but I'm guessing it might be applicable to other languages as well.</p>
<p>I've noticed that between PHP4 and PHP5, the designers of the language shifted away from using <code>-1</code> as a return value to using constants or other forms of output. This makes sense, as <code>-1</code> is not particularly evocative, and I'm guessing this practice led to confusion.</p>
<p>That said, I am sometimes inclined to return <code>-1</code> when I want to quickly add another return option to a function, and <code>-1</code> often seems like a perfectly valid way to express the outcome I am coding for. </p>
<p>So here are my questions:</p>
<ol>
<li><p>Is my observation generally correct, regarding the move away from <code>-1</code> as a return value in PHP5 vs PHP4?</p></li>
<li><p>What are the cons of returning <code>-1</code>, beyond for the reason I mentioned above, wherein the <code>-1</code> return value doesn't contribute positively to code clarity?</p></li>
</ol>

Which way of checking for Document ready() is better in jQuery from a performance point of view?

<p>I've read <a href="http://viralpatel.net/blogs/20-top-jquery-tips-tricks-for-jquery-programmers/" rel="nofollow">an article about 20 top jQuery tips</a> that uses the below code snippet: </p>
<pre><code>//Use
$(function(){

</code></pre>
<p>is better than using the below code: </p>
<pre><code>//Instead of
$(document).ready(function() {
//document ready

</code></pre>
<p>I've always used the second code snippet. Is there any benefit on using the first one? Why is the second code snippet is better from performance perspective?</p>

How do I make Java return a HTTP header in JSON as a Key Value Array
|
<p>I have the following as part of a method that is basically grabbing a webpage, I want to map the resulting header and body to JSON, the body is spat out as a string but ideally I want the header values split into key value so in the JavaScript I can access them directly.</p>
<pre><code>Map<String, String> assoc = new HashMap<String, String>();
Map<String, List<String>> headerMap = new LinkedHashMap<String, List<String>>();
headerMap = connection.getHeaderFields();
for (String key : headerMap.keySet()) {
assoc.put(key, headerMap.get(key).toString());
}
JSONObject returnObj = new JSONObject();
returnObj.put("header", assoc);
returnObj.put("body", sb.toString());
return returnObj.toString(); //Set digit to add indent spacing.
</code></pre>
<p>This unfortunately returns the header as a string rather than an array...</p>
<pre><code>{"header":"{cache-control=[max-age=0], content-type=[text\/html], connection=[Keep-Alive],
</code></pre>
<p>Ideally this would be more like (friendlier for javascript)...</p>

"headers": [
{"test": "testval"},
{"testb": "testbval"}

<p><strong>The CSS:</strong></p>
<pre><code>.span {

</code></pre>
<p>But no matter what IE do not seem to recognize it.</p>
<p>Looping through each resulting unexpected:</p>
<pre><code>$('.span:first-line').each(function() {
$(this).wrap('<em></em>');
});
</code></pre>
<p><strong>Bad Result:</strong></p>
<pre><code><em><span class="span">.................</span></em>

Is it safe to cast away template arguments in C++?
|
<p>I'm playing around with inheritance of template arguments in C++. I've got a Child class and a Parent class. The Parent class attempts to cast itself as the Child class. Although this does compile and appears to work, I'd like to know if it's safe to do. Here's the code:</p>
<pre><code>class Empty { };
template<class T> class Child : public T
{
public:
void do_something() { /* ... */ }
};
class Parent
{
public:
void go_crazy()
{
Child<Empty> & self_as_child = *((Child<Empty> *)this);
self_as_child.do_something();
}
}
void main()
{
Child<Parent> c;
c.go_crazy();
}
</code></pre>
<p>So, is the self-cast unreliable? It appears to work, but maybe that's just because I got lucky with my particular compiler.</p>

<p>It refers to main.css as the stylesheet to use, but when I get down into a subdirectory, i.e. /foo, the link obviously breaks because it's pointing to main.css and not ../main.css. What's the best way to guarantee it always points toward that top-level where main.css lives? I've got </p>

Problems accessing newly built elements
|
<p>This one is killing me :(. I'm loading saved filter sets and building each filter dynamically, inside a $.get() response function. I'm finding that, even though I'm correctly creating unique IDs for each of my selects and inputs, I'm not able to access the values of these inputs while inside the function that builds them. I tried multiple ways of adding delays to the jQuery selection process but nothing worked.</p>
<pre><code>function onSavedFilterChange(item){
$.get('url',
function(response) {
//filters with uniquely ID'd inputs get built here
//Can't access them here, immediately after creation
}
);
// Can't access them here either
}
$(document).ready(function(){
$('#randomButton').click(function(){
// but here, I can access the new inputs!!
});
});
</code></pre>
<p>My way of adding the elements is a bit complicated and may be the root of my problems. For each saved filter set returned, I start by cloning an initialized div and setting it's id attribute:</p>
<pre><code>newFilter = $('#initialFilter')
.clone()
.removeAttr('id')
.attr('id', 'fd_'+filterCount);
</code></pre>
<p>This div has three inputs; the first two are selects, the third can be a select or a text input. After that div has been cloned, I set the value of the first select like so:</p>
<pre><code>var thisSelect = newFilter.find('select.filterBy');
var thisFieldName = rows[filterCount-1]['FIELD_NAME'];
thisSelect.val(thisFieldName);
</code></pre>
<p>Next, depending upon the value of thisFieldName, I build the options of the second select using another ajax call, and I build the third input using yet another ajax call.</p>
<p>And it just occurred to me... because I'm modifying an existing site built with ColdFusion, the last two ajax calls are called through ExtJS ajax proxies. I'm gonna bet that ExtJS isn't playing nice with jQuery and I'm going to have to rewrite those two functions.</p>
<p>Either that or I'm insane to nest get calls inside get calls???</p>
