trying to reenter IT field after a break of over 5 years
|
I have had some misfortune in life - I was unwell and had to stay out of work for an extended period of about 5 years.Before that I used to work as an Oracle/Oracle Ebusiness suite consultant (I was charging very good contract rates). But now I am fully recovered ,feeling sharper than ever. But there arent many opportunities in my areas of expertise in a small market like New Zealand and the long absence is no help either. So for the last 5 months I have been training myself in C# ,ASP .NET,WEB technologies like HTML,JQuery,CSS and also SQL Server.I had some previous experience with JAVA and VB .NET (few months). But I am fully confident of my abilities and believe I can hit the ground running given a chance.I used to be an expert with SQL and C language and these skills are portable to SQL Server and C#.
Another problem I face is my age- I am over 50.
What is your opinion - Am I doing the right thing. Can I get back into an IT career-I am willing to start all over again at a junior level, I am really facing a crisis in my life.

Next step and IBM Web-based training: any good ?
|
I am a junior, lone developer at my company. I have some years of experience in other areas of IT, but I am now mostly in a software developer role. I have generated and maintained some simple-yet-efficient applications for a couple of years now, but I realize my skills are still rough and my knowledge not very broad.
Having coded before in Oracle PLSQL and PHP, I am fairly new to Object-Oriented Programming, using mainly VB .NET in my daily work. I want to learn more about OOP and methodologies.
- What do you think would be a next
step in my learning as a sodftware
dev ? I am thinking of picking up
some UML and Design Patterns
knowledge.
- Has anyone taken [IBM Rational
web-based training][1] ? Do you think
it is any good ?
This is a major concern, as I have no colleagues or tutors here to learn from. Also, I am not talking about "hard skills" like Java or C#; rather, I want to learn techniques and methodologies that will help me go prepare for a future position in a more "professional" (dev shop) development environment.

Excel VBA Newbie, help please
|
I'm new to excel VBA though I tried putting efforts but of no luck.
Problem Statement: I have a sheet with Source (color white) row and Destination (color Yellow) row, for each source there is a corresponding destination row in next line. I have to look for an application name which user input at the beginning and will search throughout the sheet (more than 10000 rows) in column 6 and it must extract the source row also if found in destination and destination row also if found in source row in sheet2.
And also one cell may have many application name within it so it should trim all other app names from that cell and leave only the searched app name.
Here is the partial code i tried :
Sub GetInterfaceCounts()
Dim RANGEBOTTOM As String
Dim cell
Dim strAction As String
Dim intAdd As Integer
Dim strName As String
intAdd = 0
RANGEBOTTOM = "G700"
strName = InputBox(Prompt:="Please enter the application name.", _
Title:="Application Name", Default:="Application")
For Each cell In Range("G2:" & RANGEBOTTOM)
strAction = cell.Value
If InStr(1, strAction, strName) <> 0 Then
intAdd = intAdd + 1
End If
Next
MsgBox "Total number of " & strName & " counts are :" & CStr(intAdd)
GetMS4AppInventory (strName)
End Sub
Sub GetMS4AppInventory(strName As String)
Dim strAction
Dim intAdd As Integer
Dim RowIndex As Integer
RowIndex = 0
Sheets("Sheet1").Select
'For Each cell In Range("G2:G700")
With Worksheets("Sheet1").Range("G2:G700")
Set strAction = .Find(strName, LookIn:=xlValues)
'strAction = cell.Value
If Not strAction Is Nothing Then
Do
If InStr(1, strAction, strName) <> 0 Then
Rows(strAction.Row).Select
Selection.Copy
Sheets("MS4Inventory").Select
Rows(RowIndex + 1).Select
Selection.Insert Shift:=xlDown
Rows(RowIndex + 2).Select
Application.CutCopyMode = False
Selection.Insert Shift:=xlDown, CopyOrigin:=xlFormatFromLeftOrAbove
Cells(RowIndex + 3, 1).Select
End If
Set strAction = .FindNext(strAction) //gets hanged here go to infinite loop
Loop While Not strAction Is Nothing
End If
If anybody could help me it will be great else manually doing seggregation of inventory will suck me.
Regards
Vijay

End Sub

How can I write this regular expression for Java?
|
I have a string which reprsents a mathematical expression. I wish to break it up into tokens, via the String.split() command.
I know that I basically want to use the regular expression: <code>"[0-9]+|[*+-^()]"</code> but that I must not be escaping the right things because it isn't working.
I want it to split all integers: 0-9, and all operators *+-^().
So, 578+223-5^2
Will be split into:
578
+
223
-
5
^
2
What do I need to do to: <code>"[0-9]+|[*+-^()]"</code>, to make it work with java's split command?

2. http://tinymvc.org & http://code.google.com/p/php-tinymvc/ - Adrian Wieczorek
3. http://code.google.com/p/tiny-mvc/ - Hung-Fu Aaron Chang

BATCH/CMD: Print each line of a .txt into a variable
|
Goal: Have every dll file in a computer passed into regsvr32.exe
Accomplished:
cd\
::REM Exports every file and directory (/s) into a file in root of c: called dir.txt with only file names (/b)
dir /s /b>>dir.txt
::REM Now, this will contain every extension type. We only want dll's, so we findstr it into dll.txt:
findstr ".dll$" dir.txt>>dll.txt
The Kink:
Now, if I want to regsvr32.exe "file" every file that is now in dll.txt, I somehow need to get out every individual filename that is individually on each line. I was wondering if there is a third party command line tool that can export each line of the file into a variable. This way, I could:
==========
::REM assume this tool had switches /l for the line number, and /v:"" for variable to use, and used "file" at the end:
set line=1
:loop
set dll=
tool.exe /l %line% /v:"dll" "dll.txt"
::REM We if defined here because if the line doesn't exist in dll.txt, the tool would return nothing to the variable.
if not defined %dll% exit
::REM With the variable defined, we can continue
regsvr32.exe %dll%
set /a line=%line%+1
goto loop
=======================
Then the tool would process each path of each line of the file until it exits automatically, because there would be no more lines. Notice right after loop I set dll to nothing so that 'if not defined' will work each time.
If this type of third-party tool cannot be done, is there a way to do that with for??
I honestly never learned for, and tried to but could never figure it out.
Any help is greatly appreciated!
Sorry if this has already been answered.

In ASP.NET, trying to find the assigned visibility value of a control that may be inside an invisible container
|
I am trying to find out whether a particular control on an asp.net page has had it's "Visible" property assign to true or false. The problem is that the visible property crawl up the list of parents and if any of them show as invisible, the queried control will also show as invisible. I need to know what the control itself has been set to.
I did some searching and found the post http://stackoverflow.com/q/2005322/487909 which offered the following solution
public static bool LocalVisible(this Control control){
var flags = typeof (Control)
.GetField("flags", BindingFlags.Instance | BindingFlags.NonPublic)
.GetValue(control);
return ! (bool) flags.GetType()
.GetProperty("Item", BindingFlags.Instance | BindingFlags.NonPublic)
.GetValue(flags, new object[] {0x10});
}
But when I tried it, it returned an "Ambiguous Match Found" error on GetProperty.
Can someone point out what I'm doing wrong, or show another way of getting what I want?

Strange Core Data Error During Migration
|
I'm absolutely pulling my hair out with Core Data after yet another bizarre error that I can't seem to solve.
This will be the fourth version of the Data model, the previous migrations have worked (albeit with some headaches).
All I'm trying to do is add a property of String type to an 'Engines' entity. I create a new version of the model (version 4) based on the current version (v3). I select the newly created version 4 as the 'Current model' and add the string property to the Engines entity. I then create a new mapping model, using v3 as the source and v4 as the target. I delete the previous Engines NSManagedObject subclass, and create a new one using the new, modified Engines entity, checking to make sure that the new String property is in the header file. I clean build the app and run it, and boom! I get this error, about 18 times:
{NSDetailedErrors=(
"Error Domain=NSCocoaErrorDomain Code=1570 \"The operation couldn\U2019t be completed. (Cocoa error 1570.)\" UserInfo=0x6015820 {NSValidationErrorObject=<NSManagedObject: 0x60a4ec0> (entity: BodySet; id: 0x60ba670 <x-coredata://F868DFA6-CB09-46AC-9CCE-73FC12C8BD98/BodySet/p14> ; data: <fault>), NSValidationErrorKey=availableCar, NSLocalizedDescription=The operation couldn\U2019t be completed. (Cocoa error 1570.)}",
BodySet is another entity in the model, but I haven't touch it during this migration, so why is causing all these errors?
I'm not sure if this is a help or not, but here's my Core Data code:
- (NSManagedObjectContext *) managedObjectContext {
if (managedObjectContext != nil) {
return managedObjectContext;

Strange Core Data Error During Migration
===
I'm absolutely pulling my hair out with Core Data after yet another bizarre error that I can't seem to solve.
This will be the fourth version of the Data model, the previous migrations have worked (albeit with some headaches).
All I'm trying to do is add a property of String type to an 'Engines' entity. I create a new version of the model (version 4) based on the current version (v3). I select the newly created version 4 as the 'Current model' and add the string property to the Engines entity. I then create a new mapping model, using v3 as the source and v4 as the target. I delete the previous Engines NSManagedObject subclass, and create a new one using the new, modified Engines entity, checking to make sure that the new String property is in the header file. I clean build the app and run it, and boom! I get this error, about 18 times:
{NSDetailedErrors=(
"Error Domain=NSCocoaErrorDomain Code=1570 \"The operation couldn\U2019t be completed. (Cocoa error 1570.)\" UserInfo=0x6015820 {NSValidationErrorObject=<NSManagedObject: 0x60a4ec0> (entity: BodySet; id: 0x60ba670 <x-coredata://F868DFA6-CB09-46AC-9CCE-73FC12C8BD98/BodySet/p14> ; data: <fault>), NSValidationErrorKey=availableCar, NSLocalizedDescription=The operation couldn\U2019t be completed. (Cocoa error 1570.)}",
BodySet is another entity in the model, but I haven't touch it during this migration, so why is causing all these errors?
I'm not sure if this is a help or not, but here's my Core Data code:
- (NSManagedObjectContext *) managedObjectContext {
if (managedObjectContext != nil) {
return managedObjectContext;
}
NSPersistentStoreCoordinator *coordinator = [self persistentStoreCoordinator];
if (coordinator != nil) {
managedObjectContext = [[NSManagedObjectContext alloc] init];
[managedObjectContext setPersistentStoreCoordinator: coordinator];
}
return managedObjectContext;
}
- (NSManagedObjectModel *)managedObjectModel {
if (managedObjectModel != nil) {
return managedObjectModel;
}
NSString *path = [[NSBundle mainBundle] pathForResource:@"CoreDataTest" ofType:@"momd"];
NSURL *momURL = [NSURL fileURLWithPath:path];
managedObjectModel = [[NSManagedObjectModel alloc] initWithContentsOfURL:momURL];
return managedObjectModel;
}
- (NSPersistentStoreCoordinator *)persistentStoreCoordinator {
if (persistentStoreCoordinator != nil) {
return persistentStoreCoordinator;
}
stringByAppendingPathComponent:@"<Project Name>.sqlite"]];
//get the DB from the Documents directory:
NSURL *storeUrl = [NSURL fileURLWithPath: [[self applicationDocumentsDirectory]
stringByAppendingPathComponent: @"<Project Name>.sqlite"]];
NSLog(@"Loading DB at path: %@", [storeUrl path]);
NSError *error = nil;
persistentStoreCoordinator = [[NSPersistentStoreCoordinator alloc]
initWithManagedObjectModel:[self managedObjectModel]];
NSDictionary *options = [NSDictionary dictionaryWithObjectsAndKeys:
[NSNumber numberWithBool:YES], NSMigratePersistentStoresAutomaticallyOption,
[NSNumber numberWithBool:YES], NSInferMappingModelAutomaticallyOption, nil];
if(![persistentStoreCoordinator addPersistentStoreWithType:NSSQLiteStoreType
configuration:nil URL:storeUrl options:options error:&error]) {
/*Error for store creation should be handled in here*/
NSLog(@"Something went wrong....%@", [error description]);
}
return persistentStoreCoordinator;
}
Any help with this is very much appreciated.

How to allow null date in Spring 3 MVC
|
I've defined a global formatter for date bindings:
<annotation-driven conversion-service="conversionService" />
<beans:bean id="conversionService"
class="org.springframework.format.support.FormattingConversionServiceFactoryBean">
<beans:property name="converters">
<beans:list>
...
</beans:list>
</beans:property>
<beans:property name="formatters">
<beans:set>
<beans:bean id="dateFormatter"
class="org.springframework.format.datetime.DateFormatter">
<beans:constructor-arg><beans:value>dd/MM/yyyy</beans:value></beans:constructor-arg>
</beans:bean>
</beans:set>
</beans:property>
</beans:bean>
This is working fine but now the problem is: I need that a particular date field can be blank. How can I configure the formatter (or this very field) to accept null value?
Thanks! :)

Implementing CSRF into OpenID iframe
|
I've implemented Janrain Open ID on my Codeigniter 2.0 website. It was working great until I enabled CSRF protection in my codeigniter config file.
I read up on it and it seems that in all my forms on my website I should include a hidden form element containing a token, which is then verified against a cookie token after the post is read from the receiving page.
This is all fine and dandy, but where I'm a bit stuck is when I try to log into my site now using OpenID (of which the login form comes from an iframe that is hosted on janrain.com) I cannot include any sort of hidden post values because I have no control over what the form looks like, and can only supply a return url so that janrain knows what page to return me to.
**How can I get my CSRF token to submit with the form if the form is in an iframe which I don't control?**

Python: Indentation Error
|
My younger cousin somehow got hold of a python book and has been trying to learn Python. He's asked me for help. But I'm having trouble doing that.
He is using IDLE and he reports that he gets this error:
Error: Inconsistent indentation detected!
1) Your indentation is outright incorrect (easy to fix), OR
2) Your indentation mixes tabs and spaces.
To fix case 2, change all tabs to spaces by using Edit->Select All
Followed by Format->Untabify Region and specify the number of
Columns used by each tab.
He sent me a copy of his code, and the indentation is correct in it. It fails to run because of a number of syntax errors, but that's not important. He reports that he used the Format->Untabify Region but the problem was not fixed.
I can't for the life of me figure out why I can run his python file, but he can't. Does anybody have any idea what is going on with that? I'm sadly currently located a five hour plane flight away else I'd physically see what was going on.

What would be the best server for a bandwidth sensitive Google App
|
I have a Google App developed in php. Google App Engine is not an option since it does not support php (but Python). We have hosted the app in MT, but our users are not satisfied of the speed and response delay.
This application communicates a large amount of data with Google API. The requirement is a high band width web server. We plan to go for a VPS for the next year and up-scale to a dedicated server after that.
What we need is not only outgoing bandwidth. More than server to client bandwidth, we will need high volume data transmission (both ways) with Google Servers. For every 1MB from server to client, there will be 10MB from Server to Google API.
Can anyone recommend a good server for this specific requirement.

Well-respected technical/developer blogs written by non-famous people
|
Many of us probably follow the technology blogs of well-known names - Joel Spolsky, Jeff Atwood, etc.
Many of us probably also follow the technical blogs of people we've come to know through our careers or our interactions. These could be blogs of exceedingly high quality that are just not as well known.

Regex search and replace across multiple files
|
I need to refactor some code across multiple php files stored in multiple folders.
Code instances like:
trim(ucfirst($userinfo['first_name'])).' '.trim(ucfirst($userinfo['last_name']))
Need to be replaced with:
formatUserName($userinfo['first_name'],$userinfo['last_name'])
Note that the $ variable name will be different, but everything else will be the same*.
I am on a Windows machine, but have php and perl installed - would prefer to use that instead of sed.
*There are variations of this line in our code, which once I have an understanding of how to build the proper regex, I'll attempt on my own.

Probability density function between -1 and 1?
|
I'm currently using Gaussian distribution as a [mutation operator](http://www.iue.tuwien.ac.at/phd/heitzinger/node27.html) for my genetic algorithm. However, I only want to obtain values between -1 and 1. I also don't wish to truncate my Gaussian distribution, which leaves me with lots of 1's and -1's.
What type of probability density function can I use to obtain values between -1 and 1, based on a mean value between -1 and 1?
Here's an image for the distribution that I'm looking for with mean values of 0, -0.5, and 0.5:

Get 2 strings from a random dictionary in a .plist
|
I am new to iphone programming. I have been struggling with this problem and have tried so many different online solutions but can't get the desired result.
I want to display 2 strings from a random array or dictionary (i'm not sure what is best to use) It would show a random question with the paired answer. Here's what i have so far:
<dict>
<key>q2</key>
<array>
<string>answer2</string>
<string>question2</string>
</array>
<key>q1</key>
<array>
<string>answer1</string>
<string>question1</string>
</array>
</dict>
.m:
NSString *fileContents = [[NSBundle mainBundle] pathForResource:@"questions" ofType:@"plist"];
NSMutableDictionary *plistDict = [[NSMutableDictionary alloc] initWithContentsOfFile:fileContents];
NSMutableArray *array = [plistDict objectForKey:@"q1"];
srandom(time(NULL));
int r = arc4random() %[array count];
NSString *arrayData1 = [array objectAtIndex:r];
NSString *arrayData2 = [array objectAtIndex:r+1];
label1.text = arrayData1;
label2.text = arrayData2;
This shows the correct result. But obviously its only picking it out of the 'q1' array. I would like to be able to get it from any array. Any help would be greatly appreciated. Thanks.

Trouble with inner joins in hibernate (HQL)
|
I'm using Struts+Spring+Hibernate and I'm having trouble getting my HQL to execute properly.
I have four objects, objectA, objectB, objectC, and objectD. Object A has a one to many relationship with Object B, and they are related as ObjectB has a FK ObjectA.Id. This pattern continues through the objects ie Object B has a one-many relationship with Object C etc.
What I've been doing right now is calling "FROM ObjectXVO WHERE objectXId = ?" to get a list of objects. My application is becoming more complicated so I need to do some more complicated HQL.
Essentially what I need is, given ObjectBVO.objectBId I need to return certain columns of the ObjectA that has the given ObjectB, certain columns of the ObjectCs that are part of the given ObjectB, and ALL columns of the ObjectDs that are part of the ObjectCs that are part of the given ObjectBs.
This is my SQL Statement that I'm using in Microsoft SQL Server. It's working and hopefully will demonstrate my model.
SELECT ObjectB.ObjectBID, ObjectB.ObjectBName, ObjectC.ObjectCDescription,
ObjectD.*, ObjectA.ObjectAID
FROM ObjectB, ObjectC, ObjectD, ObjectA
WHERE ObjectB.ObjectBID = 2
AND ObjectA.ObjectAID = ObjectB.ObjectAID
AND ObjectB.ObjectBID = ObjectC.ObjectBID
AND ObjectD.ObjectCID = ObjectC.ObjectCID
This is the code in the DAOimpl object I'm attempting to use to return List< ObjectDVO >
List<ObjectDVO> objectDs;
try{
String hql = "SELECT ObjectBVO.objectBId, ObjectBVO.objectBName,
ObjectCVO.objectCDescription, ObjectCVO.objectCId,"
+" ObjectAVO.objectAId, ObjectAVO.objectAName, ObjectDVO"
+" FROM ObjectBVO, ObjectAVO, ObjectCVO, ObjectDVO"
+" WHERE ObjectBVO.objectBId = ?"
+" AND ObjectAVO.objectAId = ObjectBVO.objectAId"
+" AND ObjectBVO.objectBId = ObjectCVO.objectBId"
+" AND ObjectDVO.objectCId = ObjectCVO.objectCId";
objectDs = getHibernateTemplate().find(hql, objectBID);
}
This just throws an error saying null. I've looked at the HQL documentation and some tutorials but it's not really clear how to do this more multiple VO objects. Can anyone help? Thanks.

VB.NET Bound ComboBox SelectedValue does not display
|
I bind a datatable to the combobox.DataSource on load. I then give the combobox a DisplayMember and a ValueMember (2 different columns out of the datatable). In the SelectedIndexChanged of the combobox I would like to use the SelectedValue property of the combobox, just to test I MsgBox(combobox.SelectedValue) and I get "Argument 'Prompt' cannot be converted to type 'String'." Why isn't it displaying the value? :(

gtk_init(&argc, &argv);
window = gtk_window_new(GTK_WINDOW_TOPLEVEL);

How to get ajax querystring from javascript given data object
|
When you make an ajax request using jquery you can specify the data property that will be passed to the sever. If the data contains an array of objects it passes it to the server in format something like this:
MyArray[0][MyPropertyA]=123&MyArray[1][MyPropertyA]=456
Is there a way to get the query string it will generate for the ajax request without actually doing the ajax request?

How to design a comment system using Entity Framework?
|
I am developing a web site where users can comment on things, which are completely independent types using Entity Framework. For example a user can comment on:
- Pictures
- Videos
- Comments
- and so on
So, I want a comment class which have a navigation property to user who wrote the comment and the thing(Picutres, Videos, Comments) the comment written to.
public class User
{
public AccountInfo AccountInfo;
public List<Comment> Comments;
}
public class Comment
{
public int Id;
public User WrittenBy;
public Thing(?) WrittenTo; // How should this part be?
}
The aim is to access comments from a User object and then get the thing which the comment was written to. I can derive all the thing classes from a base class like Commentable and then use inheritance. But I want to know if there is an elegant solution.

OPENQUERY on SQL Server 2005 64bit behaves weird
|
I just recently moved a SQL DB from SQL2005 32 bit --> 64 bit. I am having an issue connecting to Oracle using the OraOLEDB.Oracle Provider.
I was able to install Oracle 10G Client , ODAC 64 bit. I was also able to add a linked server to the Oracle instance. I am able to run a query using the linked server name directly:
SELECT top 10 *
FROM [DB0PBB0]..[DB0PBB0].[DM_CLICK]
So far it is good, however, the problem occurs when I try to use OPENQUERY. I tried the following:
select * from
OPENQUERY(DB0PBB0,'select * from DB0PBB0.DM_CLICK where Date_stamp <''24-Jul-09'' and Date_stamp >= ''23-Jul-09'' ')
SET FMTONLY OFF
select * from
OPENQUERY(DB0PBB0,'select * from DB0PBB0.DM_CLICK where Date_stamp <''24-Jul-09'' and Date_stamp >= ''23-Jul-09'' ')
and I get only the column names, no rows :(
if I run this script:
SET FMTONLY OFF
select * from
OPENQUERY(DB0PBB0,'select ''hello'' from dual ')
I get
> hello
My question is, has anyone tried running OPENQUERY against Oracle from a SQL05 64bit ? Any ?Idea why would I get only columns back instead of data? I tried the same query on another server with the same link and it worked, it returned rows.

I know how to play mp3 files and whatnot in Xcode iOS. But how do I play a certain frequency.. Like if I just wanted to emit a C# note for 25 seconds how might I do that? (The synth isn't as important to me as just the pitch of the note)

Venmo transactions
|
I am interested in finding out more about how transactions are processed within Venmo (https://venmo.com/info/product) ie
- How individual user accounts are created, and associated with their wells fargo account
- how their servers interact with individual users banks, and some more info on Verisign security
- how accounts are verified (Yodlee?)
- how transactions are processed so quickly (1 business day)
I understand most of this is proprietary information/code but would appreciate any "best guesses" or points in the direction of more info.
Thanks!

MS UnitTest - Private Accesor not always recognized
|
This problem doesnt occur in all projects, hence it makes it even more frustrating.
If I click on a Private method to create a unit test, it would generate a TestProject assembly and create a predefined class in there. It woudl also create a Accessor for that class.
[TestMethod()]
[DeploymentItem("xxx.Client.dll")]
public void PopulateIncomeCostsDataSetTest()
{
CashFlowOperations_Accessor target = new CashFlowOperations_Accessor(); // TODO: Initialize to an appropriate value
CashflowModel cashflowModel = null; // TODO: Initialize to an appropriate value
CashflowDataSet ds = null; // TODO: Initialize to an appropriate value
target.PopulateIncomeCostsDataSet(cashflowModel, ds);
Assert.Inconclusive("A method that does not return a value cannot be verified.");
}
As long as I create this unit test for private methods in a library assembly (dll) its all fine, but if I create it for a Console application where `[DeploymentItem("xxx.exe")]` is an executable, my Accesor stays in red color and I cant access the internal private methods of that accessor.
Has anyone experienced this problem before?
Many Thanks,

Sotred Procedure could not be found
|
We use SQL server 2008 as our RDBMS and we have a database that has a different user rather than dbo as its owner.
The problem is in one machine a stored procedure can not run unless its owner is mentioned.
If we connect to our database using this user and try to execute the following :
exec ourSP
we get a "could not find ourSP" error but this works fine:
exec user.ourSP
Does anybody knows what can lead to such a strange behavior?

Class variable defined at @implementation rather than @interface?
|
I'm new to Objective-C, but I am curious about something that I haven't really seen addressed anywhere else.
Could anyone tell me what is the difference between a private variable that is declared at the `@interface` block versus a variable that is declared within the `@implementation` block outside of the class methods, i.e:
@interface Someclass : NSObject {
NSString *forExample;
}
@end
vs.
@implementation Someclass
NSString *anotherExample;
-(void)methodsAndSuch {}
@end
It seems both variables ( `forExample`, `anotherExample` ) are equally accessible throughout the class and I can't really find a difference in their behaviour. Is the second form also called an instance variable?

MVVM - connect to grid in main window
|
I had a simple application where I opened a user control in the main window and placed it in a grid:
private void MenuItem_Click(object sender, RoutedEventArgs e)
{
DataViewUC _dataViewUC = new DataViewUC();
this.mainGrid.Children.Add(_dataViewUC);
Grid.SetColumn(_dataViewUC, 2);
Grid.SetRow(_dataViewUC, 2);
}
I changed it to a MVVM application and try to do there the same (open the user control in the cell of a grid):
public void ShowDataView()
{
_dataViewUC = new DataViewUC();
DataViewModel dataViewModel = new DataViewModel();
_dataViewUC.DataContext = dataViewModel;
}
But how do I get access to the grid in the main window?
This is not working here:
this.mainGrid.Children.Add(_dataViewUC);
Grid.SetColumn(_dataViewUC, 2);
Grid.SetRow(_dataViewUC, 2);

How to avoid reference count underflow in _NSCFURLProtocolBridge in custom NSURLProtocol in GC environment
|
The basics are I have a custom `NSURLProtocol`. In `startLoading`, `[self client]` is of type
<_NSCFURLProtocolBridge> {NSURLProtocol, CFURLProtocol}
The problem is running this in a garbage-collected environment. Because I'm writing a screensaver, I'm forced to make it garbage-collected. However, the _NSCFURLProtocolBridge protocol seems to always throw:
malloc: reference count underflow for (memory_id_here), break on auto_refcount_underflow_error to debug
An example dump to the debug console is:
ScreenSaverEngine[1678:6807] client is <_NSCFURLProtocolBridge 0x20025ab00> {NSURLProtocol 0x200258ec0, CFURLProtocol 0x20029c400}
ScreenSaverEngine(1678,0x102eda000) malloc: reference count underflow for 0x20025ab00, break on auto_refcount_underflow_error to debug.
You can see that the underflow is `0x20025ab00` for `<_NSCFURLProtocolBridge 0x20025ab00>`
When I break on `auto_refcount_underflow_error`, it seems to stack-trace back up to `URLProtocolDidFinishLoading:` in:
id client = [self client];
...
[client URLProtocolDidFinishLoading:self];
This problem seems to have existed for a while, but there seems to be no answer at all online:
http://lists.apple.com/archives/cocoa-dev/2008/May/msg01272.html
http://www.cocoabuilder.com/archive/message/cocoa/2007/12/17/195056
The bug only shows itself in garbage-collected environments for these listed bugs as well. Any thoughts on how I can work around this without causing memory issues? I'm assuming this probably has something to do with the CF type underneath NSURLProtocol being released improperly?

How can I get a list of SQVI queries by User ID?
|
Just as some background, I intend to write an Excel add-in with .NET that can execute queries from an SAP system.
Thus, I'm looking for a list of function modules for SAP's SQVI transaction. I can't seem to find much information about them; the few forum posts I had found before seem to have gone into the internet oblivion.
Specifically, I want to be able to look up the queries created by a user and then display the results in Excel. I can manage the Excel manipulation as well as remotely executing SAP function modules; I simply can't find which SQVI function modules I need to execute.

URL Sniffing in Python
|
Does anyone know how to write a live data sniffer in Python which extracts the originating IP address and the full URL that was being accessed? I have looked at pulling data from urlsnarf however IPv6 is not supported (and the connections will be to IPv6 hosts).
While I can pull data from tcpdump and greping for GET/POST that would leave me with simply the path on the webserver, and I would not obtain the associated FQDN. Unfortunately using SQUID w/ IPv6 TPROXY is not an option due to the configuration of the environment.
Does anyone have any ideas on how to do this with Python bindings for libpcap? Your help would be most appreciated :)
Thanks :)

Algorithms for detection of fingertips or nails
|
Can you give me some advices on what could be the best algorithm(s) to use for detection of fingertips/nails in image. First thing that crossed my mind was Viola - Jones, but I'd like some more advices. Also, as this is going to be a student's project with a purpose of learning, I'am not allowed to use OpenCV or similar frameworks. Below is typical image that will be processed. (note it's not top-down view). There is no need for thumb detection.

Who is responsible for your UI / User Experience?
|
Looking for input from all, though mostly interested in small engineering teams / small companies (10 - 20 people) that develop web applications:
1. Who is responsible for the overall look and feel of your UI (i.e. setting standards)? Is this person a dedicated resource or does he / she have other responsibilities? What type of background does this person have?
2. What about the look / feel of individual features? The BA's that design the features? The engineers that implement them? A combination of both? Somebody completely separate (i.e. engineer codes core functionality and passes it on to somebody else to "pretty it up")?

How to add widget configuration activity to launcher?
|
I have a widget with a configuration activity.
Currently the configuration launches when you click on the widget.
I want to add the configuration as an app icon to the launcher.
The problem is that when the configuration launches on click, I get a specific widget id , so each widget instance can have a different configuration.
What will happen if I start the activity from the launcher?
I wont be able to show multiple configurations on the same activity.
Thanks.

iterating through TWO sparse matrices
|
I'm using boost sparse matrices holding bool's and trying to write a comparison function for storing them in a map. It is a very simple comparison function. Basically, the idea is to look at the matrix as a binary number (after being flattened into a vector) and sorting based on the value of that number. This can be accomplished in this way:
for(unsigned int j = 0; j < maxJ; j++)
{
for(unsigned int i = 0; i < maxI; i++)
{
if(matrix1(i,j) < matrix2(i,j) return true;
else if(matrix1(i,j) > matrix2(i,j) return false;
}
}
return false;
However, this is inefficient because of the sparseness of the matrices and I'd like to use iterators for the same result. The algorithm seems straightforward, i.e.
1) grab the first nonzero cell in each matrix, 2) compare j*maxJ+i for both, 3) if equal, grab the next nonzero cells in each matrix and repeat.
What I'm wondering is (a) is there a better way to do this and (b) is there a simple way to get the "next nonzero cell" for both matrices? Obviously, I can't use nested for loops like one would to iterate through one sparse matrix.
Thanks for your help.

# do cool things here and print the new self.test
print self.test

self.test.append('test from B')
class C(A)

Graphs and ASP.Net MVC
|
I have a graph which I would like to represent using an image on a website. The problem is generating this image dynamically based on the current state of the graph.
I'm using ASP.Net MVC 3 with C#.
I've been thinking about generating the image on the harddisk using some tool(Graphwiz etc.) and then passing the path of the file to the view.
Security isn't a real issue, as this is just internal project based work for now, it is much more important that its easy to implement.
I've been trying quickgraph, and eventually i've had it generating DOT files (apperently it ignores my attempts to make PNG's) but the code fails because the program don't have access to where the files are generated. I suppose this is easy to fix, though.
Do you have any suggestions to how I could do this (If i should do something completely different or how i can get the DOT files rendered as PNG)?
Best regards,
Daniel

UIAccelerometer which moments it manage ?

The apple developer documentation explains the handled movement by this image :
![Developer documentation][1]
[1]: http://i.stack.imgur.com/BDAZU.jpg
I'm pretty confused now... because doing some tests i get that the Accelerometer doesn't handle translation on the axis but a little set of rotations ... in example if i move my device on the `X` axe nothing happen .. if i rotate it on the `Z` i get acceleration on `X`.
Here the code i use for my test:
-(void)accelerometer:(UIAccelerometer *)accelerometer didAccelerate:(UIAcceleration *)acceleration{
[self.sliderX setProgress:fabsf(acceleration.x)];
[self.sliderY setProgress:fabsf(acceleration.y)];
[self.sliderZ setProgress:fabsf(acceleration.z)];

In plain English, why is it "possible" to translate Python code to say C, but not possible to translate Perl code to say C?
|
Been looking at the differences between Perl, Python, and Ruby -- and this to me has been one of the most interesting differences I've found so far, that being that it appears it's possible to [transcribe Python into C][1], but it's not possible to transcribe [Perl into any language][2]. Haven't found anything about Ruby, but guessing that it's approach to 99.99% of everything is a object might make this hard if not impossible to do a transcription to another language.
Main focus of this question is finding an answer in plain English of why Python, Perl, and Ruby are what they are when it comes to porting them to another language.

Illegal prime numbers: What is it exactly?

I don't know if you know this situation, but sometimes I'm just browsing from one Wikipedia page to the next. So I also saw [this one][1] about illegal primes. I read the article and it sounds really interesting, but I didn't really understand what it's really about.
As far as I understand illegal primes are prime numbers that can be somehow use to generate malicious code? But how? Are there any other examples than the one in the article?
And what is the real life use of them?

Messed up someone's site - need urgent help
|
Few days ago I was editing 3 files on some site that's run by ArticleLive CMS and the site is hosted on Godaddy. On that hosting account (croatia.org) there are 3 or 4 other sites (domains) too and the. In the root folder there is index.php which forwards to croatia.org/crown. I didn't do any big changes (added few icons and edited css file). Suddenly (at the same time when I was making and testing those changes) the site stops working - actually none of the links on site are working except Links (and Forum which is outside crown folder) and they forward to Page Not Found (currently they are forwarding to the crown folder). First thing that crossed my mind is that this could be the problem with url rewriting.<br>
I have tried following:<br>
- Downloaded some of the files from crown folder necessary to display data from database
- Tried it locally and locally I can open all links
- Uploaded it on one of my hosting servers (not Godaddy) and it also works - sinj.com.hr/crown (the same folder structure exists in croatia-org/crown2 but none of the links work)
- We've spent hours and hours with hosting support but nothing helped.
We have also tried to restore full site but it didn't help. I have also tried small url rewrite test and in that case it works (www.croatia.org/rtest/sdfsdf). A day before this happened I have tried to compress some of the folders using [sitebackup.php][1] file in order to make easier backup - possible that this caused some changes on the server (although gd's support says they don't see any changes?
Is it possible that some of the files from folders that are outside the crown folders could influence this?
There are really too many folders there and I would like to avoid deleting everything to check if that's the problem... any suggestions?
Thanks in advance!<br>

App architecture: Node.js, Socket.io and MongoDB
|
I recently competed in the [Node Knockout][1] and after the contest realized that my (unfinished) app had completely wrong architecture.
I am new to the Node world in general, about a month and a half of experience with it so I was hoping that someone could help me understand what would have been a good architecture.
What we had was a game doing real time communication in the browser. We were storing the game as a variable inside of `io.sockets.on('connection')` and that was clearly a major problem with timing because it would be possible to have a Game object that wasn't up to date. I realized after the contest that I should have been storing the Game object somewhere else. It was already stored in the database, but is it fast enough for "real time" gameplay to grab the Game from MongoDB on every Socket.io event instance?
If anyone has any links discussing architecture of applications like this please share, or better yet, share your personal experiences as SO needs more discussion about Node.

What is out of box features in sharepoint. The features which we can develop through the code are know as out of box features? I am confused to know about it. I wonder if any one has an explanation. These are new in sharpeoint 2010 or existed in WSS3.0 also?

Where can you find fun/educational programming challenges?
|
I've searched around for different challenge sites, and most of them seem to be geared towards difficulty in problem solving logically, rather than trying to use your language of choice to do something you haven't used it for. Their center is around mathematics rather than function design.
Some kind of point system for correctly solving challenges, or solving them the most efficient/smallest would be neat as well.

show table deleted message in webpage when it is deleted from database

I've to show errors in backend database or server in frontend.
(like table deletion,mismatch password,server connection etc.)
I am not getting idea to do this.
I've done:

<script type="text/javascript">
$(document).ready(function() {

} else if (jqXHR.status == 404) {
alert('Requested page not found. [404]');
} else if (jqXHR.status == 500) {
alert('Internal Server Error [500].');
} else if (exception === 'parsererror') {
alert('Requested JSON parse failed.');
} else if (exception === 'timeout') {
alert('Time out error.');
} else if (exception === 'abort') {
alert('Ajax request aborted.');
} else {
alert('Uncaught Error.\n' + jqXHR.responseText);
}
}
});
});

while executing from front end, I delete the table test_tbl from the back end, but the webpage is not showing any alert. I also typed the wrong pwd but also
it did not show any error. how can I solve this problem??
I've to show **alert boxes** when:
**when there is no table in the backend**.
the above ajax code shows alert boxes for n/w errors but **how to show alert box when there is no table in database or mismatch password/username**???

Wordpress Centralized Managament
|
Are there any tools or how to setup the system which can manage the Wordpress verion or contents from one side?
As I did a research, I found manageWP and infiniteWP.
**manageWP** looks to pay money and it is quite expensive.
**infiniteWP** is quite OK, but actually I need is that there will be only one pack of Wordpress files/plug-ins/themes . All domains will share those files except their own content files - upload folder.
For example, assume that foo.com and bar.com are in the centralized system. They should ...
- Those domains will use the same and actual Wordpress files. That means, if I changed wp-mail.php in the root folder, they will see the same thing that I did a change.
- As well as the plug-ins and themes, they are also shared to foo.com and bar.com, but it depends on users.
- In case of they are get hacked, just fix only one file or one time. Then, all domains will be fixed.
Actually, I tried to setup the system by my own hand. But it is quite to make a lot of modification in both database and files. That's really hard.
Any help with this would be much appreciated.

RoR web service and mobile app development cicle design
|
i wanted to ask a couple of questions about web services with Ruby On Rails and mobile applications design cycle. I would like to know about how to design a project.
Lets say i would like to create a web service based on web app (RoR3) and mobile app (iOS and Android for instance). Obviously, if you don't create the basic structure for the web service in RoR (data base model, users, services, etc), you can't start with mobile development.
But the main question is, how a project should be approached? i mean, if you have a team of developers (art designer, front-end designer, back-end developer in RoR, iPhone art developer, iOS developer, etc), how do you approach diferent stages and phases, which one is first, etc?
-the timeframe
-developing cycle
-layout - mockup
-list of features
-core engine
-database model
thank you very much in advance!

Relation between programming languages
|
I was wondering about the following questions:
1. What does it mean "some language is
a subset/superset of another"? Can
it be defined in mathematics? Is it
related to the subset/superset
concept in elementary set theory?
2. Are almost all existing languages
implemented/written in some small
number of low-level languages? For
example, are most languages written
in C? Is C++ written in C?
Is there some relation between the
implementation relation and the
concept of subset/superset of
languages?
3. In terms of language features, some
languages have more than some other.
In some cases, some has all the
features of some other, for example,
does C++ have all the features of C?
Is there some relation between the
subset/superset relation in terms of
the set of features and the
subset/superset relation between
languages?
4. Are there other aspects that
characterize relation between
languages?
Thanks and regards!

web parts in asp.net mvc
|
This might be the most trivial question asked, but I raise it again. Am planning to get started with asp.net MVC on a personal project and here am struck if it supports webparts or any other alternative to it is present. I intend to have a start page similar to igoogle or pageflakes, but my initial research pointed out that as there's no ViewState nor Postback concepts in ASP.NET MVC implementing web parts is not possible.
If that is the case, are there any resources which helps in building a start page as the one i wish to using MVC.

"Back button" - Native support for ajax
|
Its been a while since ajax has gone main stream with the most popular websites using it (in some or other form). Also, during this period, almost all major browsers have had more than one major release yet we do not see native support for the "Back Button", and handling the event on back button press in case of ajax based requests is left to scripting 'hacks'.
What are challenges in having native support for back button in case of Ajax for browsers? Why has it still not been implemented?

How to group text columns into one column.
|
I need something like :
SELECT dt, (???) AS C FROM (SELECT dt,c1,c2,c3,c4 ...
dt - datetime and by the way I've got some weird structure , for example :
24.02.2011 null null null "text"
25.02.2011 null "te" null "text"
26.02.2011 null "te" null null
it must became
24.02.2011 "text"
25.02.2011 "te"
25.02.2011 "text"
26.02.2011 "te"
or maybe
24.02.2011 "c4" "text"
25.02.2011 "c2" "te"
25.02.2011 "c4 "text"
26.02.2011 "c2" "te"
if I do `select dt, с1+с2+с3+с4 as C from select dt,c1,c2,c3,c4`
there will be
25.02.2011 "tetext"
so I need any idea how can I exchange rows+columns to rows.
thank you.

jQuery snippet that won't work in IE7
|
I use the following snippet to move a table to another column. It works in all browsers except IE7 (didn't test lower than that). It seems like the remove() is actually removing the contents of the var, too, and not just the remaining element I set employment to. Any guidance is appreciated!
bQuery('#bsd-contribution-header-employment').parent().nextAll().andSelf().wrapAll('<table id="employment" />');
var employment = bQuery('table#employment').html();
bQuery('table#employment').remove();
bQuery('td.contribcolumn:last').append(employment);

I have this iOS app idea but since it is my first app, hopefully one of you can give me advice.
The app stores posts of different categories. I want there to be tab bars at the bottom to navigate between those categories.
On each category should be a table view. And each tableviewcell stores the post. I think the cells should be a custom view so it will give the user options to vote up/down.
These posts should be drawn from an online database.
Any ideas would be appreciated!

Everything moves to the right - Cocoa Touch
|
I have 2 landscape views. Once the app starts everything is fine. But once I go into the second view, everything decides to move abit to the left leaving a White space. And when I switch back to the first view the White space is still there. Bit of a weird flaw.
Thanks

UILabel Small Shifts After Zoom
|
After trolling Stack Overflow for a year and finding lots of help for my various iPhoneSDK issues, I need some help with an issue I have not found any clues on how to solve, if it is solvable at all.
My issue is this: After zooming into or out of my UIScrollView/UIView-based app, the text and frames of the various UILabels shift slightly after I re-render them based on the scaling factor passed into scrollViewDidEndZooming. This is most noticeable if small zooms are done. I have created a test application to show this here: <http://dl.dropbox.com/u/10939606/UILabelZoom.zip>
Is this something that can be fixed with my current UIScrollView/UIView implementation (and if so how?) or would I need to switch to a different method of displaying the text? Thanks for any help!

General classes/source code for solving Java algorithmic problems?
|
I need to build a small repository of algorithms with implementation and description. I found recently, for example, an efficient permutations generator for permutations of arbitrary length. Where can I find full source code implementations with short descriptions of other such algorithms?
Anything covered in the Java API is not needed, so I don't need Euclid's algorithm for GCD, as that's implemented in BigInteger.
Solutions for max-flow/prims/etc. are all welcome, as well as any useful algorithm-solving/creating Java tools.

Third party Application's Idle Session expiry
|
We have a third party application running. It shows login dialog when idle for 20 minutes. We need to prevent the application to display login screen.
We do not have any idea how idle state is handled internally in that application.
We have done the follwoing with no luck.
1. Created an small application in c# which focus it after every 5 minutes (using [SetForegroundWindow()][1]) and send a [BM_CLICK][2] message to one of its child window. Does not work.
2. focus it after every 5 minutes (using [SetForegroundWindow()][1]) and move the cursor few pixels then restore cursor at its previous position. This does not work too!
Is there any other way to achieve the goal?

How to know the user response in window.onbeforeunload
|
I have written a function which warn a user before refreshing the (I require it for some reason).
What I also want to implement is, call another function if the user clicks on `Leave this page`. If the user clicks on `stay on this page` I have to do nothing.
`function warnuser()`
{
return "Don't refresh the page.";
}
window.onbeforeunload = warnuser;
`//if returns true call another function!`
Thank you.

Boundary representation data structure

I've been reading about using the [winged-edge data structure][1] for storing a boundary representation. However, the linked site says that this is one of the oldest data structres for storing b-reps, are there newer better ones?
Secondly, is there an implementation of this in C#?

News: news list (OOP PHP5)
|
I design the project on OOP. I started with elementary - news. Here is an example code:
// Create list for news
$newsList = new ArrayList();
// Get news from DB
$db -> executeQuery('...');
while ($newsData = $db -> getFetchArray()) {
// Create news
$newsItem = new News(array(
'newsKey' => $newsData['newsKey'],
'imageMini' => $newsData['imageMini'],
'name' => $newsData['name'],
'shortlyText' => $newsData['shortlyText'],
'addedAt' => $newsData['addedAt'],
));
// Add news item into news list
$newsList -> add(array(
'newsKey' => $newsItem -> getNewsKey(),
'imageMini' => $newsItem -> getImageMini(),
'name' => $newsItem -> getName(),
'shortlyText' => $newsItem -> getShortlyText(),
'link' => $newsItem -> getLink(),
'addedAt' => LangDateTime :: toFormat(LangDateTime :: DATETIME_FORMAT, $newsItem -> getAddedAt())
));
}
// Save news list in template
$template -> set('newsList', $newsList -> toArray());
This is double the work in the cycle while(). Can it be done easier and better? Can group you want to create a class or method NewsList in Class News. Maybe need to create a class NewsList or method in the class News.
Thanks.

Can i execute any code when my app is installed on an iPhone/iPad?
|
I would like to know if I can execute any code when my app is being (or after it's) installed on an iOS device, actually I can execute the code when the user runs the app for the first time but I don't want the first run to take so long
Thank you,

How to do reverse engineering once most efficiently?
|
RE for me is a completely new subject, so this may be naive.
I would like read data directly from the file -- the thing is the format of the file is unknown, it can be encrypted as well. I know what is in the file so I can probe it if it necessary, but I don't know how it is written (for example if "hello" is written as "hello" or "HELLO" or "h e l l o", and so on).
I figure it out that I use some RE tool and disassemble a function from the program which already reads that data. But when I checked the prices for the most popular tools (IDA Pro) it appeared that this "one time job" would cost me a lot -- IDA Pro is around 400 EUR and Decompiler for it around 1600 EUR.
Well, I cannot afford such purchase not only because I don't have such money, but simply because I am not sure if I won't fail with the task. And this is only done as a hobby.
So -- are there any others tools without not such steep prices? Or is there other approach? Writing my own disk filter driver, or something like that?
Thank you for any help in advance!
