Android set height of custom title bar
|
I made a custom title bar. In the title bar are two imageviews next to each other and one textview beneath it. It works fine but I just see the top of the textview. So I think the title bar get cropped at the underside. Does somebody know how to set the height of a custom title bar?

Iterating through IQueryable with foreach results in an out of memory exception.
|
I'm iterating through a smallish (~10GB) table with a foreach / IQueryable and LINQ-to-SQL.
Looks something like this:
using (var conn = new DbEntities() { CommandTimeout = 600*100})
{
var dtable = conn.DailyResults.Where(dr => dr.DailyTransactionTypeID == 1);
foreach (var dailyResult in dtable)
{
//Math here, results stored in-memory, but this table is very small.
//At the very least compared to stuff I already have in memory. :)
}
}
The Visual Studio debugger throws an out-of memory exception after a short while at the base of the foreach loop. I'm assuming that the rows of dtable are not being flushed. What to do?
Thanks in advance.

Is there a way to do the same thing that does clear data button from Settings->Application->Manage Applications to an application programmatically?
Or else i want on click to delete all sharedpreferences. How to do that?

List Box enable/disable one column
|
Access 2007: Is it possible to enable/disable one column in a List Box on a form. For example: Say you have 2 columns A,B - If Me.A = title Then Me.B.Enabled = True Else Me.B.Enabled = False.
If so, where would it go? On Got Focus, On Click??
Thanks

Now I am being asked to use Classes and move functionality into the classes. Specifically, you should have at least the
following classes:
1. A Bank class which consists of an array of Accounts and the number of accounts currently active in the bank.
2 An Account class which consists of a Depositor, an account number, an account type, and a balance.
3 A Depositor class which has a Name and a social security number.
4 A Name class which consists of first and last names.
You must add appropriate member functions (or methods) to each class so as to implement the functionality of each of the
functions of the previous assignment (HW2). Each of the functions of HW2 should be re-implemented using a class method.
HE GAVE US A CLUE AS TO HOW WE CAN GET STARTED:
1. The Bank class should have at least have the following methods:
openAccount(...)
getBalance(...)
getAccountInfo(...)
makeDeposit(...)
makeWithdrawal(...)
closeAccount(...)
2. The Account class should at least have a constructor that would allow statements of the form:
account[j] = Account(...);
3. The Depositor class should at least have a constructor that would allow statements of the form:
depositor = Depositor(...);
4. The Name class should at least have a constructor that would allow statements of the form:
name = Name(...);
5. Add additional methods to each class as necessary.
6. All I/O should be done outside of the class implementations.
I DONT KNOW WHAT TO PUT INTO THESE POSSIBLE METHOD PARAMETERS TO GET THESE FUNCTIONS TO WORK AS THEY WERE BEFORE THE CLASS SPECICIFICATIONS AND IMPLEMENTATIONS. CAN SOMEONE POINT ME THE RIGHT DIRECTION OF HOW TO GET THIS GOING PLEASE!!!!

Now I am being asked to use Classes and move functionality into the classes. Specifically, you should have at least the
following classes:
1. A Bank class which consists of an array of Accounts and the number of accounts currently active in the bank.
2 An Account class which consists of a Depositor, an account number, an account type, and a balance.
3 A Depositor class which has a Name and a social security number.
4 A Name class which consists of first and last names.
You must add appropriate member functions (or methods) to each class so as to implement the functionality of each of the
functions of the previous assignment (HW2). Each of the functions of HW2 should be re-implemented using a class method.
HE GAVE US A CLUE AS TO HOW WE CAN GET STARTED:
1. The Bank class should have at least have the following methods:
openAccount(...)
getBalance(...)
getAccountInfo(...)
makeDeposit(...)
makeWithdrawal(...)
closeAccount(...)
2. The Account class should at least have a constructor that would allow statements of the form:
account[j] = Account(...);
3. The Depositor class should at least have a constructor that would allow statements of the form:
depositor = Depositor(...);
4. The Name class should at least have a constructor that would allow statements of the form:
name = Name(...);
5. Add additional methods to each class as necessary.
6. All I/O should be done outside of the class implementations.
I DONT KNOW WHAT TO PUT INTO THESE POSSIBLE METHOD PARAMETERS TO GET THESE FUNCTIONS TO WORK AS THEY WERE BEFORE THE CLASS SPECICIFICATIONS AND IMPLEMENTATIONS. CAN SOMEONE POINT ME THE RIGHT DIRECTION OF HOW TO GET THIS GOING PLEASE!!!!
THANK YOU

Trouble in implementing link list sorting in c#
|
I am having trouble implementing a sort algo (merge) for singly list as defined below
My mergesort method always gives me null..I am not able to figure out what is wrong
Can you guys help me out?
Node class
public class Node
{
private int data;
private Node next;
}
Linked List class

return;
AlternateSplitting(a, x, y);
MergeSort(x);
MergeSort(y);
a = SortedMerge(x, y);

I implemented following helper methods to implement merge sort
AlternateSplitting: This method will split the list into 2 lists

{
while (src.Head != null)
{
MoveNode(odd, src);

return b;
else

Images tile on Google map in android
|
I am developing an android application where I have place image tiles on Google map in android.
I can do with simple javascript but can anyone tell how I do this in android.Here is my JavaScript code.
function initialize() {
var center = new google.maps.LatLng(37.4419, -122.1419);
var map = new google.maps.Map(document.getElementById('map'), {
zoom: 3,
center: center,
mapTypeId: google.maps.MapTypeId.ROADMAP
});
var globalfoovar = new google.maps.ImageMapType({
getTileUrl: function(tile, zoom) {
return "http://demoserver.com";
},
tileSize: new google.maps.Size(256, 256),
opacity:0.60,
isPng: true
});
map.overlayMapTypes.push(null); // create empty overlay entry
map.overlayMapTypes.setAt("0",globalfoovar); // set the overlay, 0 index
Can any translate the above to android Google map.
Thanks in android

Java Eclipse+Jigloo. Abstract class
|
I'm using eclipse with jigloo plugin. I have an abstract class - NewFrame, and a class which extends it - UserFrame. When I'm trying to open UserFrame with Jigloo GUI, there is a mistake: "Error: The class UserFrame extends the abstract class NewFrame - you should implement the getGUIBuilderInstance method for UserFrame."
I found the decision [here][1], so I created NewJFrame-class with constructor and added getGUIBuilderInstance()-method to UserFrame-class. But it still doesn't work. I'm doing something wrong?

Available screen size on Linux in QT 3

QDesktopWidget * screen = QApplication::desktop();
QRect size = screen->availableGeometry(this);
Qt doc says,
What is available will be subrect of screenGeometry() based on what
the platform decides is available (for example excludes the Dock and
Menubar on Mac OS X, or the taskbar on Windows).
What I want to know is how can i get available screen geometry (without panels) on LINUX ? I tried above code on linux, but it returns physical screen size.

MySQL order by not working with join
|
I am attempting to create a mysql query that ranks MMA fighters based on their score, and whether or not they are professional, and their weight class, together creating a fighters division. I have a table with all of the fighters that contains their weight, status (professional or amateur), and a bunch of other columns. I also have a table that contains scores that are calculated from all of their fights. The records need to be ordered by both division and score, but I can only get my query to order by the division:
INSERT INTO fa_rankings (fighter_id, rank, division)
SELECT
fa_scores.fighter_id,
@r := CASE WHEN @div <> f_division THEN 1 ELSE @r+1 END as f_rank,
@div := f_division
FROM
(SELECT @div := NULL) d,
(SELECT @r := 0) r,
fa_scores
JOIN (SELECT fa_fighters.fighter_id,
CONCAT(
IF(status = 'professional', 'a', 'b'),
CASE
WHEN weight < 126 THEN 0
WHEN weight BETWEEN 126 AND 135 THEN 1
WHEN weight BETWEEN 136 AND 145 THEN 2
WHEN weight BETWEEN 146 AND 155 THEN 3
WHEN weight BETWEEN 156 AND 170 THEN 4
WHEN weight BETWEEN 171 AND 185 THEN 5
WHEN weight BETWEEN 186 AND 205 THEN 6
WHEN weight BETWEEN 206 AND 265 THEN 7
ELSE 8 END) as f_division
FROM fa_fighters
ORDER BY f_division ASC) as fighters using (fighter_id)
ORDER BY score DESC
I'm guessing this has something to do with where the last order by statement is, but I can't figure out where else to put it, because it doesn't work with in the joined query. Right now this query generates the following:
Rankings Table Compared with Scores
+------------+------+----------+ +-------+
| fighter_id | rank | division | | score |
+------------+------+----------+ +-------+
| 131 | 1 | a1 | | 0 |
| 23 | 2 | a1 | | 34 |
| 332 | 3 | a1 | | 4 |
| 1233 | 1 | a2 | | 0 |
| 643 | 2 | a2 | | 44 |
+------------+------+----------+ +-------+
EDIT: I had previous query that did not use a join, but that only grouped by whether or not the fighter was professional, and that query did apply the rankings correctly, so I suspect it has something to with the join.

Android TextView carry text by letters
|
Is there any way to carry text in TextView by letters in Android?
If no settings have been set – TextView carries text by words and situation is possible when with too long word you have big whitespace in TextView.
Example – what I’m talking about:
![Carry text by words][1]

type = db.Column(db.Integer)
def __init__(self,title,question,lang=0,type=0):
self.title = title
self.question = question
self.lang = lang
self.type = type
Now if i do
collection = db.session.query(Collection).get(1)
collection.questions does not return a list of questions, instead it returns the following query.
SELECT question.id AS question_id, question.title AS question_title, question.question AS question_question, question.lang AS question_lang, question.type AS question_type
FROM question, collections_questions
WHERE :param_1 = collections_questions.collection_id AND question.id = collections_questions.question_id
Any help would be greatly apprecieted!

Jqgrid on rails
|
I am unable to get proper documentation on using jqgrid in rails. Client part is working fine. That is, I am able to make AJAX call using jqgrid. I am able to receive all parameters like page, rows etc. I am not sure on how to send my data back to client. Server side code is not querying the db. It is some having code where I make many rest calls(like to twitter) and few parsing to create an array of object. What is the best way to send data.
Ex code: Server side
T1 = Triple.new(1,2); // creating new object of type Triple(fname, lname)
T2 = Triple.new(3,4); // creating new object of type Triple(fname, lname)
T << T1 //Adding it to array
T << T2 //Adding it to array
// How to construct final json out of the above mentioned array for jqgrid?
Do I need to use any gem in rails part? Or can I just construct json object and send that. A sample code for above mentioned example will be really helpful.
Sample client code which I am planning to use
jQuery("#tb2Id").jqGrid({
url:'/reference_uri.json
datatype: "json",
colNames: ['First Name', 'Last Name'],
colModel:[
{name:'Name',index:'fnames', width:55}
{name:'Name',index:'lnames', width:55}
],
rowNum:10,
rowList:[10,20,30],
pager: '#pager',
viewrecords: true,
caption:"JSON Example"
});

jQuery Ajax Combo box not working
|
I have the following combo box which sets the number of images displayed per page. I had the original php code working, but I am having a lot of trouble using jQuery to change it to Ajax.
It appears the combo box part is working, but it's hard to tell as the images are not displaying.
I'm hoping someone can help me.
**The HTML**
<form>
<label>Images Number:</label>
<select id="imgNum" name="imgNum">
<option value="12">12</option>
<option value="16">16</option>
<option value="20">20</option>
</select>
</form>
<div id="imgTray"></div>
**The jQuery**
//Bind the onChange event to Fetch images on combox selection
$("#imgNum").change(function(){
//The combo box
var sel = $(this);
//Selected value
var value = sel.value();
//Fetch the images
$.get("get_images.php",{imgs: value}, function(data){
//Add images to the document
$("#imgTray").html(data);
});
})
//You should store the current selected option in a cookie
//For the sake of the example i'll set the default permanently to 12
var imgNum_selected = 12;
//set the initial selected option and trigger the event
$("#imgNum [value='"+imgNum_selected+"']")
.prop("selected","selected")
.change();
**The PHP**
<?php
if((int) $_GET['imgs'] > 0){
$limit = (int) $_GET['imgs'];
} else {
$limit = 12;
}
$curPage = 0;
if(isset($_GET['page'])){
$curPage = (int) $_GET['page'];
}
$mysql_link = mysql_connect("localhost", "root", "root");
mysql_select_db("new_arrivals_imgs") or die("Could not select database");
$query = mysql_query("SELECT `imgURL`,`imgTitle` FROM `images` ".
"ORDER BY `imgDate` DESC LIMIT " . $limit * $curPage . ", $limit") or die(mysql_error());
if(!$query) {
echo "Cannot retrieve information from database.";
} else {
while($row = mysql_fetch_assoc($query)) {
echo "<li><a href='new_arrivals_img/".$row['imgURL']."' class='gallery' title='".$row['imgTitle']."'><img src='new_arrivals_img/thumbnails/".$row['imgURL']."'></a></li>";
}

Justifying Text Java
|
I came across a question in an old computer olympiad where you are required to justify text in java.
Bassically, you are given a sentence that stays the same throughout the program for example:
The existence of religion in all of the world's major societies is the result of the process of Darwinian natural selection. Religion is a set of beliefs made by the elders in a society to enforce the moral values necessary to preserve the society which exploits a belief and supernatural powers to enforce “the rules.”
The user inputs the column width (how many characters should fit on a line) and then the text is outputted as such.
eg column width 13
The existence
rest of text

How to completely quit an android apllication?
|
I'm facing a similar issue like [this one][1]. I'm using some static class members inlcuding singletons in my aplication. When I leave the main activity using finish() and start it again, all static members are still present. It seems not to be a good soloution to call Process.killProcess(Process.myPid()); and I also don't want to need to unset all static members when I leave the application because this is error-prone when extending the application. So how would one completely quit an android application properly?

Colour the border of an image in a map
===
I am using MS Chart control, where in within a point chart I have to populate some mini charts (pie or bar) based on the position of the points.
And when the user clicks or hovers over those point it should fire some events (circle/mark the image border or show data). I have completed all except the last part, I cannot apply the css to the image border.
I will paste the rendered html from the page here:
<html>
<head>
<title></title>
<script src="Scripts/jquery-1.7.2.min.js" type="text/javascript"></script>
<script type="text/javascript">
function showData(pie) {
debugger;
$(pie).css("border-width", "thick");
$(pie).css("border-color", "Red");
$(pie).css("border-style", "dotted");
}
</script>
</head>

Random numbers 1-6
|
Im trying to create a simple high/low app but the application crashes when I try to get a random number.
Here is some code:
final TextView counter = (TextView) findViewById(R.id.tcounter);
Button high = (Button) findViewById(R.id.bhigh);
Button low = (Button) findViewById(R.id.blow);
Button start = (Button) findViewById(R.id.bplay);
final Random rstart = new Random();
final int counternr = rstart.nextInt(5) + 1;
start.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
counter.setText(counternr);
That is supposed to set the TextView "counter" to a random number from 1-6, but gives me a crash.
Thanks in advance!

Parameter binding of POST action method
|
You can see what **GET Delete** action method passes DDW2File object to view. Is it possible somehow to bind this object back to **ddw2file** parameter of **POST Delete** action method? Now I have **null** value in it.
Code fragment:
public class DDW2FileController : Controller
{
...
public ActionResult Delete(string fileName)
{
return View(repository.GetFile(fileName));
}
[AcceptVerbs(HttpVerbs.Post)]
public ActionResult Delete(DDW2File ddw2file)
{
repository.Delete(file);
return View("Index", repository.Files);
}
}
...
public class DDW2File
{
public string Name { get; set; }
public long Length { get; set; }
}
Thanks!

Can a Backbone.js View have a Model and a Collection?
|
Can a Backbone.js `View` have a `Model` and a `Collection`?
The reason I am asking is because I'm working with a View that holds a map with places plotted on it (using the leaflet library).
The `Collection` is of a group of models that hold coordinates to be plotted on the map.
The `Model` holds stuff like the map bounds and map shape.
Not sure how else to pull this one off...
Any help is appreciated, thanks!

have div fadein on video "ended" only if it's the last in an array

Basically, it's what the question says. I need a div to fadeIn and another fadeOut (or show, I just used fadeIn) when a video ends, but only when it's the last video in an array of 6. I have
$("#myVid").bind("ended", function() {
if(currentVideo == videos.length) {
$(".control").fadeOut();
$("#final").fadeIn();
}
and I've tried
$("#myVid").bind("ended", function() {
if(currentVideo == 6) {
$(".control").fadeOut();
$("#final").fadeIn();
}
so, I should be doing it's job, but something isn't doing it, but I can't figure it out... Can I get some help here?

Password strength checking library
|
Can anyone recommend a Java library that contains methods that are suitable for performing server-side password strength checking in a webapp. Ideally the checker should be:
- configurable, allowing the deployer to supply different dictionaries, adjust weights of different criteria, and so on
- extensible allowing new criteria to be implemented if required
- implemented in pure Java
- not fundamentally intertwined with a tag libraries, UI components or "password management" functionality
- compatible with a GPL 3 project
- compatible with Spring wiring
- mavenized (ideally available through Maven Central)

Does anyone know how to write a permutation in Java when the start and end can very per digit?
Ex: The first digit can be 1 to 5, but the second can be 1 to 8 and the third 1 to 3?

Use JQuery to do server side validation then send user to another site
|
I want to 'postpone' (stop the default behavior of the form) sending the user to 'http://www.othersite.com' until server side validation is finished on check.php
Once complete, send the user on their way to 'http://www.othersite.com'. I can send to the validation page no problem, but I need to validate then send to another website. Say I have a form like this
$(document).ready(function(){
$('#sendbutton').click(function(){
$('#error').empty();
$('#send').ajaxForm(function (data, textStatus) {
$('#error').append(data);
});
});
});
<form id="send" name="send" method="post" action="http://www.othersite.com/index.htm">
<input type="text" id="fname" name="fname" />
<input type="text" id="lname" name="lname" />
<input type="text" id="address" name="address" />
<input type="text" id="city" name="city" />
<input type="text" id="state" name="state" />
<button id="sendbutton">Submit</button>
</form>
<div id="error"></div>
And server side validation occurs on check.php
check field inputs here on check.php
if not correct
echo error message
if successful echo "validation_ok"
If the returned data is 'validation_ok' then send the user to complete form submission on 'http://www.othersite.com'

Percona MYSQL / Ruby mysql2 gem - Data loss on insert
|
I'm not sure which is causing the problem: whether it is mysql itself or the ruby mysql2 gem, but I am experiencing some data loss in my queries.
I am using mysql2's multi_statement support, so I have a series of INSERT statements separated by a semi-colon like so:
INSERT INTO some_table (col) VALUES (val); INSERT INTO some_table (col) VALUES (val2)
The problem with this is that if I have more than three statements, the **3rd** statement gets lost. It doesn't return errors or anything, it just skips the insertion process, so, for example, I have 10 INSERT statements, only 9 are inserted.
Does anyone know how this is? Or have you experienced a similar situation?

Prevent implicit import of units in Delphi packages
|
Is there a way to prevent packages in Delphi to implicitly import units that are not listed in the "Contains" list? I'm looking for a compiler directive that makes the build to fail if it tries to do an implicit import.
Problems occur when you install a package into the IDE that implicitly imports unit A and then you try to install another package that really contains unit A and the IDE tells you that it cannot install that package because unit A is already contained in the first package even if it shouldn't be!

Second level cache with NHibernate filters?
|
I am configuring 2nd level cache with NHibernate 3.0. 2nd level cache works great for Entities and Collections but I also have some Entities which have filtered collections.
<bag name="EntityTrans" cascade="all-delete-orphan" table="EntityTrans">
<key column="entityId" not-null="true" />
<one-to-many class="MyDomain.EntityTran, MyDomain" />
<filter name="cultureFilter" condition=":cultureCode = CultureCode" />
</bag>
NHibernate 2nd level caching does not cache the above collection. My NHibernate config file has the following entries.
<class-cache class="MyDomain.EntityTran, MuDomain" region="MyRegion" usage="read-only"/>
<collection-cache collection="MyDomain.Entity.EntityTrans" region="MyRegion" usage="read-only"/>
Do I need to add something more to cache the filtered collection?

Getting started with GDI+ and creating a 2d drawing program
|
I have never done anything with a windows c++ GUI and I need to make basically a 2d drawing application using GDI+ where there is a grid to draw shapes on. I cant find any information on getting started on doing this. What are some good resources to look at to learn how to do this?
The goal is to have a program where the user can click a button to pick a tool then draw with that tool on the grid.

Double self-referencing property with Entity Framework
|
This code represents in small scale my problem:
public class Person
{
public int ID { get; set; }
public string Name { get; set; }
public virtual Person Parent { get; set; }
public virtual ICollection<Person> Friends { get; set; }
}
When I use this class in an Entity Framework (4.1) scenario, the system generates one only relation, thinking that Parent and Friends are the two faces of the same relation.
How can I tell to semantically separate the properties, and generate two different relations in SQL Server (since we can see that Friends are totally different from Parents :-)).
I tried with the fluent interfaces, but I think I don't know the right calls to do.
Thanks to all.

Toolbar not showing in UIView

I am having different views in one Xib file and am moving from one to the next and back. All views have a button that should reveal the same toolbar which I added in IB in its own view. Only when the toolbar gets called it is always behind the view. How do I get it to show on top of the view?

Generalized least square model giving auto correlated residuals
|
I work for a financial institution, we often times run into analysis of time series data. A lot of times we end up doing regression using time series variables. As this happens, we often encounter residuals with time series structure that violates basic assumption of independent errors in OLS regression. We are building another model in which I believe we have regression with auto correlated errors. The residuals from linear model (lm(object)) clearly has a AR(1) structure, as evident from ACF and PACF. I fit the model using Generalized least square model using gls() in R. My expectation was that the residuals from gls(object) is white noise,but residuals from gls(object) still have the same ARIMA structure as in the ordinary regression. Unfortunately there is something wrong in what I am doing which I could not figure out. Hence I decided to manually adjust the regression coefficients from the linear model (OLS estimates). Surprisingly that seems to be working when I plotted the residuals from adjusted regression (residuals are white noise). I really want to use gls() in ‘nlme’ package so that coding will be lot simpler and easier.

JavaScript code to handle comment folding (similar to Reddit's?

I really like the way Reddit's comment system works - particulary the ability to smoothly fold/unfold a tree of comments.
Is there some standard JavaScript code/library that does this? Or did Reddit develop this inhouse and is not portable?
I'm fairly a beginner in JS, so browsing through Reddit's page source is not that helpful.

Does a SQL UNION with a LIMIT optimize away uneeded queries?
|
Say I have a sequence of queries that progressively get more expensive. I can join all these with a union but I'm only interested in the top 10 results so I add a LIMIT. The query looks something like this:
(SELECT col1, col2 FROM table WHERE colx = 'x')
UNION
(SELECT col1, col2 FROM table WHERE colx LIKE '%x%')
UNION
(SELECT col1, col2 FROM table WHERE colx LIKE '%x%' AND unindexedcol LIKE '%y%')
LIMIT 10
I know that this is not guaranteed to be the top 10 from the first query as the MySQL documentation states
> UNION by default produces an unordered
> set of rows
but in practice it appears that the results are ordered select 1 followed by select 2 etc until the limit is reached.
So does MySQL execute the queries sequentially and stop when it hits the limit? If not then what is a better way to execute this style of query where only a subset of results are needed and prioritisation of less expensive queries is preferred to minimize execution time?

Error logging into SQL Azure using manage link on Azure portal
|
I have logged into Azure and navigated to Database link. I created a new database using "create' on the azure portal. Now i try to test connectivity. It fails. So i try to debug by clicking on "manage". Here i enter the database name user id and password. It fails, stating "Login is disabled or credentials are invalid"
I am using windows azure in conjunction with Visual Studio express (trial edition). I have tried with checking the "allow other windows azure services.." box and also by providing the IP designated to the db server in firewall rules. In both cases i get the same error.
This effort is part of deploying the sample VS 2010 windows azure web application on azure. It works fine on the emulator, but fails when actually deployed, at the time for registering a user. I have changed the default connection string to point to SQL azure as described @ http://msdn.microsoft.com/library/hh369932.aspx#SQLAzure.
Any pointers would be appreciated
regards

Does anybody have suggestions for good resources and exercises on Java concurrency, particularly the new Java 5 constructs? They should have model answers ideally.

Android parse time in default timezone
|
I want to parse a time value formatted as `"12:34:56"`, which comes from an external web service, to a `Date`, `Calendar` or anything that I can later compare to current time.
The problem is that on Android, `DateFormat.parse` seems to ignore the user's default timezone and parse the value as if it was in UTC. Given this code:
DateFormat timeFormat = new SimpleDateFormat("HH:mm:ss");
String inTime = "12:34:56";
Date time = timeFormat.parse(inTime);
I get the wanted result on my desktop (Java 1.6.0_29):
Thu Jan 01 12:34:56 CET 1970
However, on Android this is one hour off:
Thu Jan 01 11:34:56 GMT+0100 1970
I even tried setting the timezone using `timeFormat.setTimeZone(TimeZone.getDefault())`, but this does not help. Is there any way to get `DateFormat.parse` to work correctly, or do I have to convert everything to UTC and back to get it working on Android?

php returns a whole html file instead of a string (ajax)

AVAssetWriter can't create m4a file on iPhone 3G

I'm trying to use AVAssetWriter to create an m4a file. It works perfectly on any devices exclude iPhone 3G. Some says, that problem is in 3G does not support AAC encoding. Is it true? if ([assetWriter canAddInput:assetWriterInput]) returns NO.
AVAssetWriter *assetWriter = [AVAssetWriter assetWriterWithURL:exportURL
fileType:AVFileTypeAppleM4A
error:&assetError];
if (assetError) {
NSLog (@"error: %@", assetError);
return;
}
AudioChannelLayout channelLayout;
memset(&channelLayout, 0, sizeof(AudioChannelLayout));
channelLayout.mChannelBitmap = 0;
channelLayout.mNumberChannelDescriptions = 0;
channelLayout.mChannelLayoutTag = kAudioChannelLayoutTag_Stereo;
NSDictionary *outputSettings = [NSDictionary dictionaryWithObjectsAndKeys:
[ NSNumber numberWithInt: kAudioFormatMPEG4AAC], AVFormatIDKey,
[ NSNumber numberWithInt: 2], AVNumberOfChannelsKey,
[ NSNumber numberWithFloat: 44100.0], AVSampleRateKey,
[ NSData dataWithBytes: &channelLayout length:sizeof( AudioChannelLayout ) ], AVChannelLayoutKey,

AVAssetWriterInput *assetWriterInput = [AVAssetWriterInput assetWriterInputWithMediaType:AVMediaTypeAudio
outputSettings:outputSettings];
if ([assetWriter canAddInput:assetWriterInput]) {
[assetWriter addInput:assetWriterInput];
}
Anybody knows, how to create m4a file on a iPhone 3G?

Writing Standard Input and waiting for Standar Output
|
I'm trying to create a Thread that keeps netsh windows command-line tool open so I can execute netsh commands without open it every single time.
The thing is, once I've created the Thread, just the first command call works... the subsequent calls seems to have no effect.
Here is my code:
public class NetshThread implements Runnable{
private static Process netshProcess = null;
private static BufferedInputStream netshInStream = null;
private static BufferedOutputStream netshOutStream = null;
public BufferedReader inPipe = null;
public void run(){
startNetsh();
}
public void startNetsh(){
try {
netshProcess = Runtime.getRuntime().exec("netsh");
netshInStream = new BufferedInputStream(netshProcess.getInputStream());
netshOutStream = new BufferedOutputStream(netshProcess.getOutputStream());
inPipe = new BufferedReader(new InputStreamReader(netshInStream));
} catch (IOException e) {
e.printStackTrace();
}
}
public void executeCommand(String command){
System.out.println("Executing: " + command);
try {
String str = "";
netshOutStream.write(command.getBytes());
netshOutStream.close();
while ((str = inPipe.readLine()) != null) {
System.out.println(str);
}
} catch (IOException e) {
e.printStackTrace();
}
}
public void closeNetsh(){
executeCommand("exit");
}
public static void main(String[] args){
NetshThread nthread = new NetshThread();
nthread.run();
String command = "int ip set address " +
"\"Local Area Connection 6\" static .69.69.69 255.255.255.0";
nthread.executeCommand(command);
command = "int ip set address " +
"\"Local Area Connection 6\" static 69.69.69.69 255.255.255.0";
nthread.executeCommand(command);
System.out.println("*** DONE ***");
}

CKEditor charset
|
I updated my web app to use UTF-8 instead of ANSI.
I did the following measures to define charset:
mysql_set_charset("utf8"); // PHP
<meta http-equiv="Content-Type" content="text/html; charset=utf-8"> // HTML
utf8_general_ci // In MySQL
I also edited the CKEditor config to remove htmlentities because I need the correct character (i.e. `é` and not `é`) for MySQL fulltext search.
config.entities = false;
config.entities_latin = false;
In the database (phpMyAdmin view) and on normal text fields output (HTML, `<input>` or `<textarea>`), everything looks fine (I see `é`, not `é`, not `é`, yay).
However, CKEditor has some trouble with the encoding. See attached image for the same field taken from the database, displayed in a textarea, then in a textarea repalced by CKEditor:
![CKEditor Encoding Problems][1]
This seems to be in the CKEditor JavaScript code (probably a fixed charset), but I can't find it in the config. Again, since the `é` displays correctly in normal HTML (real UTF-8 `é`, not `é` nor `é`), I'm quite sure it's not the PHP/MySQL query that's wrong (but I might be mistaken).

Correct way of declaring pointer variables in C/C++
|
I noticed some people use the following notation for declaring pointer variables.
(a) char* p;
instead of
(b) char *p;
I use the (b). What is the rational behind the notation (a)?
Notation (b) makes more sense to me because character pointer is not a type itself. Instead the type is character and the variable may be a pointer to the character.
char* c;
This looks like there is a type char* and the variable c is of that type. But in fact the type is char and *c (the memory location pointed by c) is of that type (char). If you declare multiple variables at once this distinction becomes obvious.
char* c, *d;
This looks weird. Both c and d are same kind of pointers that point to a character. In this since the next one looks more natural.
char *c, *d;
Thanks.

Configuring HandlerInterceptors within a @Configuration context
|
I'm using @Configuration in Spring 3.0.6 to use dependency injection without using .xml definition files.
I use a mixed approach for defining Controllers, I put them in the DispatcherServlet's @Configuration, using @Bean("/sample/path") *and* use @RequestMapping in their methods to further refine the mapping (including using it to append to the bean's path).
This works fairly well with the default HandlerMapper configuration.
Now, I want to add some HandlerInterceptors to the mix. It seems that I need to duplicate the default HandlerMapper configuration and then add my HandlerInterceptor.
However, this does not seem a great idea. Is there any way to add my HandlerInterceptor to the default HandlerMapper config?
Cheers,
Alex

I'm trying to let the user select his birthday with:
<% form_for :user, :url => users_path do |f| %>
<%= f.date_select :birthday, :start_year => 2010 , :end_year =>1920, :discard_day => true %>
<% end %>
The problem is that it doesn't get saved... birthday is a date field in the users table and to save it I call
@user = User.new(params[:user])
@user.save
what could be the problem?
Thanks

Inserting an EMF into LaTeX
|
After years of playing around with different figure formats in R I have found the one to hold it's quality best is an EMF. I have just started using LaTeX and cannot get LaTeX to read my EMFs. I am using the graphicx package (which I have read supports EMF files) but its still not reading it.
\usepackage{graphicx}
\begin{figure}[h]
\centering
\includegraphics*[width=1\textwidth]{combined_DMC}
\caption{Frequency of fires for each month of the year}
\label{fig_fire_month}
\end{figure}
I am not sure if I am telling latex to use the graphicx package (as opposed to the standard graphics package) by using includegraphics*
Thanks

Debugging a world of hell when trying to install MySQL-Python on Mac OS X
|
I've been trying for weeks and weeks to install MySQL-python with absolutely no luck, on Mac OS X 10.6 with Python 7.0 from the Enthought Python Distribution. Many of the issues I ran into have been described in other posts and I'm pretty sure I read all of those, but still cannot fix this issue. I tried installing and reinstalling various MySQL packages for 64bit OS X but finally just compiled it from scratch. MySQL, as far as I know, works and lives in the directory /usr/local/mysql-5.5.9-osx10.6-x86/.
I was able to install MySQL-python-1.2.3 using "sudo setup.py install". However, when I import it, I get the error:
$ python

I looked to see, as other posters on here suggested, what _mysql.so is referencing using otool:

/usr/lib/libgcc_s.1.dylib (compatibility version 1.0.0, current version 438.0.0)
The correct file seems to exist here:

I tried several approaches to make _mysql.so recognize this file:
1. Making symbolic links, as others suggested, to the right file:
$ sudo ln -s /usr/local/mysql-5.5.9-osx10.6-x86/lib/libmysqlclient.16.dylib /usr/lib/libmysqlclient.18.dylib
when I do this, I get a new error:

2. Setting DYLD_LIBRARY_PATH, as follows (after removing the previous symbolic link):
$ export DYLD_LIBRARY_PATH=$DYLD_LIBRARY_PATH:/usr/local/mysql-5.5.9-osx10.6-x86/lib/
Then I get the same error as initially:

Any ideas on what can be done to fix this? I'd really like to get this package working... I tried for a while and could not get it to work. I understand it's a common issue but I could not get any of the posted solutions to work.
Thanks very much for your help.

global vs local (variables and lists) by byte consumption JAVA
|
I' trying to create a web site and some times i took the PermGen exception. So i start searching for ways to reduce the amount of the created objects and also to reduce the memory consumption. I read some articles. But i'm not sure about some things. For example is better to declare lists outside of a method(global), or to create them into a method? What's the difference in terms of memory consumption at this case? If i declare them as local that means that after the use the garbage collector will collect them and thus will release space at the heap? Can anyone propose me ways to reduce more the memory consumption and the amount of the create objects(is the @Autowired better way to declare on object)?

Wt (C++) or Ruby on Rails, or Django (Python)? for a computer science student
|
I am a 2nd year computer science student and I am looking for advice. I have done JAVA and a little bit of C so far in school. In my own time I like to make small web applications because they can easily be deployed and are much easy to code compared to standalone programs. I have been using PHP for the past 3 years and was told to move on to different language to enhance my learning experience and broaden the job skills.
I want to know what language out of the three mentioned is good for:
1. Someone wanting to pursue a computer science/software engineering career.
2. Something that will help me with my degree (e.g I heard Ruby on rails helps to better understand OOP concepts)
3. A language that is in demand (Which is why I am leaning towards Wt, that case I get to practice my C++ skills)
I know it depends on what kind of application you want to build, so heres what I intend to do:
Make websites that allow :
1. Data storage (easy interface with database systems perhaps?)
2. Graphics library. I want to program a web graphics program where you can make wallpapers on the go.
Thanks

Easy but effective way of solving huge one-page site?
|
Simple question, but I'll probably go around the world a few times before I get to the point. I'm currently designing a site dedicated to 'The Legend of Zelda' called Zelda Timeline, which will follow the official timeline as revealed by Nintendo recently in their Japanese book, 'Hyrule Historia'.
The idea is you go on the site and presented firstly with an brief about and slider, then scroll down to view the game in list order. Currently, I have a one-page template set up to put each game in order, and then when 'Next' is clicked is jumps to the next game in the list. That's the easy part...
Nintendo being Nintendo, they decided to split the Zelda timeline into three parts from the game 'Ocarina of Time' so there are three parallel timelines from that game: A, B, C we'll say for now. [This image explains it better](http://chzfandom.files.wordpress.com/2011/12/timeline.png). Now, the easy option would be have Split A running straight on from the main timeline, then B, then C with the user clicking Split B, skipping Split A completely, or the user clicking Split C and skipping A and B. The only fault with this solution is that if the user wants to, they can just keep scrolling, therefore bypassing the jumps and scrolling the content out of order.
I had the idea of once you get to the game where it splits - 'Ocarina of Time' - the user is presented with three choices as above: A, B, or C. When the user presses their choice, the are taken diagonally down-left for A, down for B, diagonally down-right for C, but cannot scroll down to the actual content unless the choices is made? When the choice has loaded, the normal vertical scrolling is resumed to follow that timeline? [See this image](http://dl.dropbox.com/u/6174165/horizontal-timeline.jpg).
Is this feasible? I remember seeing a form a while ago, that once each section was filled and submitted, it loaded the next section in a horizontal manner and a mix of jQuery and AJAX comes to mind?
What are your thought and ideas on this, and would it be easy to implement for someone with decent HTML/CSS and jQuery knowledge?

CAPTCHA and it's legality?

I am sourcing some info from the OWASP (open application security community) web site (http://owasp.org) and came across some info in their Authentication section.

[http://www.owasp.org/index.php/Guide_to_Authentication][1]
They are saying that their useage is illegal due to discrimination laws in place for Disabled Citizens.
I know OWASP is pretty good for info on security, but I have to question how serious the legality of implementing something like CAPTCHA is.
So. Can anyone reference or point me in the direction of any type of documentation confirming there is an issue of legality with using CAPTCHA? Is it specific to all countries or just U.S.?
Is implmementing speech features for the CAPTCHA enough to overcome the legality?
Extra points if you can find the relevant documents to support this in Canada. As I work in Canada for a large multinational company which uses CAPTCHA extensively.
Cheers Mates!

What is the best advertisement service to put on your site?
|
I have a site I'm currently building and I want to make it free, but support it with advertisements. I see a lot of sites using Google's Adsense program and others using Ebay & Amazon. But I noticed with StackOverflow, it looks like they're partnering up directly with sellers. I have Google's adsense on my blog, but I still haven't made a cent from it. Not saying I have a great number of visitors, but I'm starting to wonder if Google is not the way to go.
What experience have you guys had with advertisements and what do you recommend?
With the new closing rules in place, I can finally get my answer. ;-)

How can I get OProfile / Xenoprof to use event counters when running on EC2?
|
I'm writing a cluster-wide profiling tool for EC2 that is designed to collect data by running OProfile on each instance. I'd eventually like to aggregate the XML output generated by opreport, and analyze it later.
Right now, I'm stuck on getting OProfile to see hardware events -- all I can do is build profiles in Timer Interrupt mode. I have a feeling this is due to the fact that EC2 instances run in a virtualized environment, where OProfile cannot see hardware events.
I looked into this hunch a bit, and came up with Xenoprof as a possible solution, but there's very limited documentation on how to get it up and running with EC2.
If anyone's had any success running Xenoprof on EC2 (and I know there must be some successes, because there are several papers about it), could you clue me in as to what's going wrong?
When I run
yum install oprofile
and then
man opcontrol
on the instance, I see the options for xen are there, which I *think* means that Xenoprof must be installed. I just don't know what to do to get the hardware events as my samples.
Any advice would be much appreciated! Thanks.

I want to find the most significant bit that is set to 1. I have tried every possible way from & to ORing all of the bits from 1 to 31 and it doesn't work. Like if 1000000 I would like to have 7. Thank you.
