Excel: if any field in a row is not null, set the cell in the first column to an incrementing row number?
|
I'm trying to create a formula that will have the effect of automatically adding an incremental row number to the first column of my spreadsheet when any data is entered in any column of the row.
So for example, if my table looks like this:
a b c d e f
1 # x x x x x
2 # x x x x x
3 # x x
4 # x
5 # x
I would like the 'a' column to read:
0
1
2
3
4
And if I added more data in any column, e.g.:
a b c d e f
1 # x x x x x
2 # x x x x x
3 # x x x
4 # x x
5 # x x
6 # x
7 # x
It would then automatically up the index row 'a' to read as:
0
1
2
3
4
5
6
I hope this makes sense! Any help, or even just a tutorial to point me in the right direction would be so appreciated!

How long should I prepare for SCJP?
|
Ok I know this might sound a bit silly, as it depends on the person, but on average how much time should I spend on preparing for SCJP? I already have some experience with Java (a few small and medium projects for my university, from implementing a simple "ships" game to some client-server stuff).
I was thinking about taking it around jun-july '10 so I'd have around 7-8months, is it enough/too much/not enough?
Also I've been looking for a good book, is there anything better than: "Sun Certified Programmer for Java 6 Study Guide" by Kathy Sierra and Bert Bates? And what about some practical questions (like "implement this and this" or "write a piece of code which does...")?
Ah and is it really worth it (I'd spend my own money). I'm not asking if it will make me a better programmer (as I've seen such a thread on stackoverflow alread) but do the employers even care about it?

When will the first CSS4-compatible browsers start showing up?

I know that CSS3 is still very new, but from what I understand, the CSS4 spec has already been partially written, and among the new features, is the much-anticipated parent element selector. When will the first CSS4-supporting browsers start coming out?

Php database creation and jscript validation
|
Need to make a page with a private registration form and invite codes. In a two step process. First the user inputs a unique invite code, the code needs to be checked through JavaScript to ensure it passes as a valid code, if not rejected. If the code appears valid it must be validated through the database with PHP, if valid in the database the user is redirected to register, if invalid the user is sent to another page.
After the user registers they are sent a confirmation email and a unique "invite code" will be automatically emailed to the user. This user can then give their invite to other users who will be can then register.
The database needs to keep track of which invite codes the users are utilizing to register.
How would I accomplish this using JavaScript and PHP and a database? Please keep in mind I am new at this and need as much help as possible. Thank you in advance for your help. Message me if you need further details.

I installed oracle 11g xe and home page was not coming up. similar thing is happening when I installed oracle 10g xe. The home page cannot be connected and run sql command line is also not opening. I checked in services.msc that OracleServiceXE and OracleXETNSListener is running.
Firewall is off. Using XP SP3. Previously had Oracle 8i and uninstalled it and deleted all its files.
I opened cmd and typed

Insert TextBoxes into a Repeater dynamically and retrieve their value
|
I have a Repeater bound from SQL, containing a mixture of editable and read-only elements. When you click the "Edit" button on a row, the editable portions should convert to textboxes, and when you click "Update", it should save your changes.
Here's a (very) simplified version of the Edit and Update buttons' OnClick code:
switch(commandName)
{
case "Edit":
Label1.Visible = false; //hide read-only version
PlaceHolder1.Visible = true; //show editing version
//Dict1 is Dictionary<string, string> in this example.
foreach (var key in Dict1)
{
//insert a TextBox dynamically into the PlaceHolder
PlaceHolder1.Controls.Add(new TextBox
{
ID = "txt" + key,
Text = Dict1[key]
});
}
break;
case "Update":
//retrieve user input from dynamically-added TextBoxes
foreach (var TextBox1 in PlaceHolder1.Controls.Where(c => c.ID.StartsWith("txt")))
{
doStuff(TextBox1);
}
Label1.Visible = true; //show read-only version
PlaceHolder1.Visible = false; //hide editing version
break;
}
The problem is that my dynamically-added TextBoxes aren't there when the page posts back. I've examined `PlaceHolder1.Controls` in the debugger, and there are no TextBoxes in it. `PlaceHolder1` itself is inside a Repeater, but I'm not rebinding the Repeater on PostBack.
I've considered using raw HTML in place of TextBox controls and pulling the values out of Request.Form, but that feels hackish to me. How can I make the dynamically-added TextBoxes persistent across postbacks?

PlaceHolder1.Visible = false; //hide editing version
break;
}
The problem is that my dynamically-added TextBoxes aren't there when the page posts back. I've examined `PlaceHolder1.Controls` in the debugger, and there are no TextBoxes in it. `PlaceHolder1` itself is inside a Repeater, but I'm not rebinding the Repeater on PostBack.
I've considered using raw HTML in place of TextBox controls and pulling the values out of Request.Form, but that feels hackish to me. How can I make the dynamically-added TextBoxes persistent across postbacks?

How do you collect programming knowledge
|
Everyday we are faced with programming problems ranging from easy to complex. For me it is important to record that knowledge so that I can find it in the future. The features that I consider that most important is recording ease of use (WYSIWIG would be good), good search capabilities and perhaps hierarchical organization or tags enabled.
**What tools do you use to collect programming knowledge?**
Try to give one solution per answer. Perhaps something like a short one liner clear description followed by a blank line and a paragraph explaining the rationale for your solution. You can include what you consider the strong and weak points of your choice.

Vertical flip of CGContext
|
I have a UIView that I am trying to render into a UIImage using [CALayer renderInContext:]. However, I find that the resultant image is flipped vertically. I kind of expect this due to the different coordinate systems. However, I then try and flip the context back to normal with an affine transform - but it doesn't have any effect:
CGAffineTransform flipVertical = CGAffineTransformMake(
1, 0, 0, -1, 0, imageContextHeight
);
CGContextConcatCTM(imageContext, flipVertical);
CGImageRef cgImage = CGBitmapContextCreateImage(imageContext);
UIImage* uiImage = [[UIImage imageWithCGImage:cgImage] retain];
CGImageRelease(cgImage);
What am I doing wrong?

Rich native client for MSDN library documentation
|
The [MSDN Library][1] provides great documentation for .NET/C#. However, the primary delivery medium, HTML via a web browser is suboptimal. A rich native Windows client for browsing this documentation seems like a perfect opportunity to showcase WPF. Is there such a client available? Are there any alternative interfaces to the MSDN Library?

I am creating a dialog in VISUAL STUDIO C++ using MFC application.
There is a sentence : First choose two edit boxes and placed them on dialog. Use the Class Wizard from the View menu to connect each to a float, value number1 or number2 .
Edit boxes are there. Now how to connect them to a float, value number 1 ? What's the procedure?
Thanks

What's wrong with Jsch and Maven?
|
I try to use Jsch 0.1.44 together with Maven.
I have the following dependency in my pom.xml.
<dependency>
<groupId>com.jcraft</groupId>
<artifactId>jsch</artifactId>
<version>0.1.44</version>
<scope>compile</scope>
</dependency>
If I run <code>mvn compile</code> maven looks normal and tells me that Jsch has been successful downloaded.
But when it comes to compile, the Jsch classes could not be found. If I look into my local repository I can see that the Jsch-jar has only a size of 3kb. If I open the jar file I can also see that there is only the META-INF folder.
So what is wrong here, how can I fix this?

Is it still worth to invest time into OpenMP implementations?
|
Since clang/llvm has no plan to support OpenMP any time soon, and Intel is going far away down the road of TBB library. Is it still worth to implement multi-thread scientific libraries (I am working on ccv: http://github.com/liuliu/ccv) on top of OpenMP? Despite all the criticisms, my experience with OpenMP is quite happy (it is super easy to use, and the performance gain is reasonable). But if it is a dying technology, what's the replacement for easier-multi-thread in C? (not pthread, and TBB is C++ thing). Thanks!

Blogging Tool Needed for Standards Compliant Webpages
|
A programmer I know has a website that is fully Standards Compliant. It uses Unicode-encoded fully-validated XHTML 1.1 with CSS. The pages are frames-free, table-free and JavaScript-free.
He would like to be directed to a blogging tool that does not demand any particular database system or web server, but does create static pages that comply with the above standards and best practices and is itself a professionally finished native Windows application.
...and it should be able to produce an RSS feed as well.
Is there anything out there that comes close to this?

iPhone chat program (with server)

I am trying to make an iPhone chat program.
Found a website that guides me to do it but I am having trouble making it work.
http://www.devx.com/wireless/Article/43551/1954
When I login, it is not showing on the textview that I logged in.
Neither C# compiler, the server side, or on Xcode, the client side, is showing the error message on the console.
Can anyone try out creating the chat programmed with the link on the top or find the problem of my chat program.
Thank you.
P.S. I used vmware to run Window 7 and MonoDevelop to create a the server.
Client Program
http://dl.dropbox.com/u/12439052/Network.zip
Server Program

Ah plus is there any iPhone Book that shows how to make a chat program, not the internal network one with Bonjour, chat program for external network, "long distance internet".
Thanks.

String search in shell
|
I'm creating a shell script to a basic program.
One option is to delete a user, but the problem is that if I search for a string that belongs to the username in question, the program will assume it as a user aswell.
For example, if I have the user adminaaa if I search for admin the program will recognize it as a user, even if "admin" is not a user.
The piece of code that I'm using is the following:
existe=`cat meusutilizadores.txt|grep "$user" |wc -l`
if [ $existe = 1 ]
then
fullUser=`grep $user meusutilizadores.txt`
passUser=$(echo $fullUser|awk -F ':' '{ print $2 }')
What I need is to be able to program it to recognize the user for his entire string, not only a part of it.
I hope I was able to express myself well enough for you to understand.
Hope you can help me.
Best regards

Use of typename keyword with template function parameters
|
In C++, the `typename` keyword is needed so the compiler can disambiguate between nested types and nested values in templates. However, there are certain situations where no ambiguity is possible, such as when a derived class inherits from a nested class type.
template <class T>
class Derived : public T::type
{ };
Here the `typename` keyword is not required, and is in fact not even allowed. This makes sense, because the context removes the ambiguity. Here, `T::type` must refer to a type, since you obviously can't inherit from a value.
I would think the same thing would hold true for function template parameters.
template <class T>
void foo(const T::type& v)
{
}
In this case, the context makes it clear that `T::type` must refer to a type, since a function parameter can't be a value. Yet, the compiler doesn't accept this. It wants `const typename T::type&`. This seems inconsistent. Why does the language allow the implicit assumption of a nested type in the context of inheritance, but *not* in the context of function parameters? In both cases there can be no ambiguity, so why the need for `typename` in one but not the other?

Is it good practice to compose an application through multiple .exe?
|
in a book - I think it was Eric S. Raymonds "the art of unix programming" - I read sth. like that applications should be built by putting multiple small tools together.
So, I would like to know if it's a good idea to develop a windows application, for example, by creating one small .exe for every task?
For example: You have a Document Managing System:
This could be put together like:
- an .exe for searching and displaying documents (GUI)
- an .exe for indexing document (put documents into a database)
- an .exe for deleting documents
- etc.
Do you think this would be a good idea or should it be put into one big .exe with multiple DLLs (this would be the way I saw most applications built)?
What would be the pros and cons?

MySQL - Limit the amount of rows in a join?

sites
id site_name
1 www.a.com
2 www.b.com
....
I'm trying to select the last 2 rows (ordered by date desc) in site_text for each site. Can you do this with one query? Something like, but have it only find 2 rows of each site?
SELECT * FROM site_text st JOIN sites s ON st.site_id=s.id WHERE st.date_added > '2010-02-01 23:32:04' ORDER BY s.id, st.date_added DESC
In the end, I would be looking for site_text.id = 4,2,5,3.

Android - Find all internal and external storage
|
So I've noticed that from device-to-device, there are many different configurations for internal vs. external. On my Evo there's just internal storage and the external SD card, but on a Droid Incredible from the same year, there's internal storage, internal SD card (~8GB) and external SD card (default 1GB). Presumably there are other configurations as well, and there will be more forthcoming.
However, all I can seem to find about enumerating the number of storage media available are things like [Environment][1], where you can do things like getExternalStorageDirectory(), which returns a File, not File[] or anything like that. Is there a safer, generalized way to enumerate all the storage media available? Do you just have to navigate to /mnt/ and get a listing there to see all the mounted volumes?

However, all I can seem to find about enumerating the number of storage media available are things like [Environment][1], where you can do things like getExternalStorageDirectory(), which returns a File, not File[] or anything like that. Is there a safer, generalized way to enumerate all the storage media available? Do you just have to navigate to /mnt/ and get a listing there to see all the mounted volumes?

Android - why ContentObserver invokes itself?
|
I am trying to delete received SMS in ContentObserver (on "content://sms/") onChange() method using contentResolver.delete, but after deleting ContentObserver is invoked one more time.
Could you explaing my, whe ContentObserver invokes itself despite deliverSelfNotifications() returns false?
I foud soultion to uregister ContentObserver before deleting the sms and register again after, but is inelegant.
My code:
private class SmsMmsContentObserver extends ContentObserver {
public SmsMmsContentObserver(Handler handler)
{
super(handler);
}
@Override public boolean deliverSelfNotifications() {
return false;
}
@Override
public void onChange(boolean selfChange) {
super.onChange(selfChange);
Uri uriSMSURI = Uri.parse("content://sms/");
Cursor cur = getContentResolver().query(uriSMSURI, null, null,
null, null);
if (cur.moveToNext())
{
int threadIdIn = cur.getInt(cur.getColumnIndex("thread_id"));
getContentResolver().delete(Uri.parse("content://sms/conversations/" + threadIdIn), null, null);
}
}
}
Methods to register observer in on of services.
private void registerSmsMmsObserver()
{
if (observer == null)
{
observer = new SmsMmsContentObserver(new Handler());
contentResolver = getContentResolver();
contentResolver.registerContentObserver(uriSmsMms, true, observer);
}
}
private void unregisterSmsMmsObserver()
{
if (contentResolver != null)
contentResolver.unregisterContentObserver(observer);
observer = null;

Scraping Data From a Dynamic Website
|
Background: The page has a table with data in it. There are several hyperlinks that when clicked, the data in the table is replaced with new data. Also, the page is an aspx page.
Goal: I want to scrape the data in the table for all hyperlinks pressed.
I have looked at what is going on via firebug and when a hyperlink is clicked, it generates an http post back to the server via ajax. The problem is that there are a lot of really garbage post parameters being sent. I assume this is because asp does some sessioning type things. I assume that even if I copied the exact parameters my browser sent, most of them won't be valid later anyway.
How do people usually write http scripts that deal with this kind of stuff?

I need help in creating my first application in MS Access 2007.
Consider a table in MS Access with a column "AgeGroup" and the possible values for this column are "Child" and "Adult". Is there an option in MS Access to enter data into this column using a combo-box with these two values in **Datasheet** view?

How to pass parameters to an action that's called on JQuery dialog() Open event
|
Good morning.
I have a modal JQuery dialog that on Open calls and loads a Partial View. Good example can be seen here http://stackoverflow.com/a/4802423/1193841 but I'll re-paste:
<script type="text/javascript">
$(function () {
$('#dialog').dialog({
autoOpen: false,
width: 400,
resizable: false,
title: 'hi there',
modal: true,
open: function(event, ui) {
//Load the CreateAlbumPartial action which will return
// the partial view _CreateAlbumPartial
$(this).load("@Url.Action("CreateAlbumPartial")");
},
buttons: {
"Close": function () {
$(this).dialog("close");
}
}
});
$('#my-button').click(function () {
$('#dialog').dialog('open');
});
});
</script>
<div id="dialog" title="Create Album" style="overflow: hidden;">
In my case ActionMethod "CreateAlbumPartial" takes an ID parameter that's passed from another page with onclick="" event.
How can I make that Id available to pass to an ActionMethod when its called as shown above ? Something like
$('#dialog').dialog('open',Id)
Would be awesome but I dont think that's how it works.
P.S. Right now I'm displaying my popup by doing $.post() to load .html(data) to div and then displaying that DIV in a .show().dialog('open').
However, instead of having my Action method call and Dialog related stuff separately I would really like to re-do it the way I'm asking to keep all logic in one place.
Thank you in advance.

Is it possible to compile flex 3 charts in intellij?
|
I'm aware that mx.charts is part of flex builder professional.
I've downloaded the trial version of flex builder professional and added the datavisualization.swc to my intellij Flex_sdk classpath. The IDE is now aware of the classes, but when I come to compile I still get:
"Type was not found"
Is there a license or something I need to add to the classpath.
Can anyone give a step by step guide to compiling a flex app that uses charts, either in intellij, or from the command line.
Thanks.

C++ Builder Forms crashing

Form 1: (frmStart)
void __fastcall TfrmStart::btnRunClick(TObject *Sender)
{
frmStart->Hide();
Application->CreateForm(__classid(TfrmRunning), &frmRunning);
}
Form 2: (Running)
void __fastcall TfrmRunning::FormCreate(TObject *Sender)
{
frmRunning->Show();
//Here i do a lot of stuff to run my main program
}
The problem is that my first form loads and hides properly. When the second form loads no components are displayed just a GUI that looks like it has crashed/. When the program actually finisihes, the GUI returns to a normal state.
Where did i go wrong?

Can you scale SQL Server to handle 100's of Terabytes?
|
One of my colleagues told me the other day SQL Server wasn't designed to handle Terabytes of data.....that could possibly be true for SQL 2000 or any DB 10 years ago, but I don't believe that to be the case today. How have others approached the situations where they need to store massive amounts of data (100 + Terabytes)? Growing one Single server is probably not the option, but I would think we could partition the data across many smaller servers and use views, etc to allow us to make one query call across the servers. Any idea how concurrency, etc performs in a model like this where data is Horizontally Partitioned across servers?
Any suggestions / comments is greatly appreciated.
Thanks,
S

MSMQ vs RabbitMQ For a .NET Project
|
I am mainly looking for pros and cons to using MSMQ vs RabbitMQ for a .NET project (to tie a web front-end to backend workers, standard enterprise setup).
Especially if you have used both, or replaced one for the other, please let me know what factors led to your decision. Reliability in case of messaging server reboot, as well as possibility for queue clustering (to enable better up-time) is crucial, so if you have experiences with how well related features work in either, that'll be really great.
Many thanks.

Importing into SiteFinity
|
I just finished installing SiteFinity 3.7 standard version on windows server 2008. Is there a way to entirely/partially import an already existing .NET project (ASP.NET) into SiteFinity with some minor changes in the code of course (may be by changinf a couple of xml files or something similar). I could only see an "export" under Administration->Tools section but no import. I am new to SiteFinity so a detailed help/guidance would be much appreciated.
Thanks.

Advantages of using SQLDataReader over a reader that implements IDatareader?
|
What are the advantages of using a SQLDataReader as opposed to a reader that just implements IDatareader if I'm using SQL Server >= 2005?
Does the SQLDatareader simply have more functionality to choose from, or are there performance improvements using the SQLDatareader?
Any articles that discuss this would be appreciated.
Thanks!

How can I calculate the trending nature of a link?
|
![enter image description here][1]
[1]: http://i.stack.imgur.com/BdhY5.jpg
The above image represents an article's page views over time. I'm looking for a decent, not to complex either physics or statistical calculation that would be able to give me (based on the history of the page views) what the current trending of the page views is for the past n days (which is represented by the blue box).
So basically, in the past 5 days is this link trending unusually higher than it usually does and if so by what degree/magnitude?
Ideally the accepted answer would provide an algorithm class that applies to this problem as well as some example of that using the data provided from this chart above.
thanks!

How do you get the fact that a cell of a datagridview has been modified without the cell losing focus?
|
I have a datagridview with a check box in it. The point is when the user clicks the check box I immediately want to perform an action. The problem I have is, If I process the cell click method this does not work if the user uses the keyboard. I can tie onto the currentcelldirtystatechanged event but this is only raised the first time the cell is changed but not subsequent times. Essentially I want to act immediately and not force the user to change the cell that is currently in focus.

Wrapper to make boost nicer? [boost beginner]
|
[Sorry, a totally boost beginner question.]
I just gave boost a first look. But already the sample code looks quite deterrent to me. I seems to consists only of scopus operators, namespaces, template instantiations, etc. Compared to MFC it looks quite bloated and not easy readable to me.
Are there any wrappers to make boost more user-friendly?

I want to change the background which I did but it still shows a red border all around (see picture http://imageshack.us/f/710/wordpressg.png/). Where do I delete the frame? Can not find it. Would also like to do the framing / page wider. Seems like I have to change several times in my css or where do I change it?

IE bug, autocomplete box position in iframe
|
After a few hours' of google search, i found that there is autocomplete box bug since almost 10 years ago, until now, on IE9 the bug is still there.
<hr/>
problem:
<br/>when i have an input:text inside iframe, there are positioning bug of the autocomplete box - tested on IE8-compatibility mode, IE8, IE9.
<hr/>
The problem maybe related to the iframe's parent class (note: may not be the style, because i tested on IE9 console, disabling the class style will not solve the problem; on the other hand, giving the same style but removing the class solved the autocomplete box positioning bug, unfortunately only on IE9).
<br/><br/>on IE8 and IE8 compatibility-mode, tried the same method, the position of the autocomplete box bug is still present: sometimes it is located around 50px below the input:text, sometimes it is about 8px above the input:text bottom (like IE9).
<hr/>
solution i founded from google result, people suggest "position:relative; left:0; top:0;", tested, doesn't work.
<hr/>
similar problem from another person: http://forums.asp.net/t/1538225.aspx/1
<br/><br/><br/>
thanks for your help

$GLOBAL associative array getting reset on page redirection
|
I tried the following code to create a superglobal variable using $GLOBALS.
test.php
<?php
$GLOBALS['test']='hello';
header("location:test3.php");
?>
Here is the test3.php
<?php
var_dump($GLOBALS);
echo $GLOBALS['test'];
?>
The output i get is
array(5) { ["GLOBALS"]=> *RECURSION* ["_POST"]=> array(0) { } ["_GET"]=>
array(0) { }["_COOKIE"]=> array(1) {"PHPSESSID"]=>string(26)"oer267anbfrrhtj64lpqrocdd3"}
["_FILES"]=> array(0) { } }
The $GLOBAL['test'] is not getting set.
But when I try var_dump in test.php,I find $GLOBAL array to have a key 'test' with value 'hello'.
What is the reason of this behaviour?
Also I wish to create a superglobal database connection object using the $GLOBAL.Is it recommended?

Vim Macro with arguments
|
I need to do some search and replace in vim regularly. Using regex I did some operations to get the desired result this time. However since these operations are a bit complicated I would like to have a mechanism where I can take the range of lines under consideration and carry out the sequential operations I have already developed.
Is this possible with vim?
Now suppose lets say everytime I have to replace a particular word with a desired word which is not fixed, can this also be passed through that mechanism.
Thanks.

How to differeniate capital letters from lower ones in onkeydown event handler method
|
<html>
<head>
<title>Test</title>
<script type="text/javascript">
function showChar(e){
if(e.keyCode!=16)
alert(
"keyCode: " + e.keyCode + "\n"
+ "SHIFT key pressed: " + e.shiftKey + "\n"
);
}
</script>
</head>
<body onkeydown="showChar(event);">
<p>Press any character key, with or without holding down
the SHIFT key.<br /></p>
</body>
</html>
How can I differentiate capital **A** from lowercase **a** in onkeydown event handler method? Above algorithm fires the same keyCode value. I need to detect the capital letters when they are pressed in onkeydown.
Note: The code contains an exception for SHIFT key. Otherwise it does not allow to type capital letters. BTW, I need to use onkeydown for my trial.

Java Input Buffer Garbage

Why is good practice to empty the 'Garbage' from the input buffer in a block of code like this? What would happen if I didn't?
try{
age = scanner.nextInt();
// If the exception is thrown, the following line will be skipped over.
// The flow of execution goes directly to the catch statement (Hence, Exception is caught)
finish = true;
}catch(InputMismatchException e){
System.out.println("Invalid input. age must be a number.");
// The following line empties the "garbage" left in the input buffer
scanner.next();

Css and jQuery: How do I trigger the repositioning of a CSS3-animated element back to where it was before the animation?
|
http://jsfiddle.net/cD4Gr/4/
Le Code:
$j(document).bind('click', function() {
$j("#test").css({ bottom:0px })
});
Looking in the inspector, even when the element is at the top of the page, it still says it's bottom value is 0.
Maybe I need to play the animation in reverse somehow? or play a different animation? (Using Bottom %, rather than top %)

XCode 4 crashes loading mapping model
|
I have a core data model, which includes two objects with a relationship named "contains" - which now that I'm trying to create a new version of the model I'm realizing is a reserved word (see this [answer][1]. I can change the name of this property in the new model, but the problem is that Xcode 4 crashes trying to deal with that property in the mapping file. If I click on either entity mapping that has the "contains" property, I get a crash - the details contain the following:
<pre>
Application Specific Information:
ProductBuildVersion: 4A304a
UNCAUGHT EXCEPTION (NSInvalidArgumentException): Unable to parse the format string "FUNCTION($manager ,'destinationInstancesForSourceRelationshipNamed:sourceInstances:' , 'contains' , $source.contains) == 1"
UserInfo: (null)
Hints: None
</pre>
If I manually edit the xcmapping.xml file in vim, find the entries for the "contains" properties, and prefix it with a '#', I can get Xcode to load the file, and show me the mapping, but after fixing the mapping, it won't save the file: I don't get an error, Xcode just hangs. I'm downloading 3.2 now to see if I can at least edit the file there - any workarounds for Xcode 4? I have reported this problem.

Just got a Windows Phone 7, when I put in my google account, the phone pulled down every person I’ve ever emailed and placed them in the “people” hub. I only want people that I have phone numbers for as contacts. With android there was a way to display contacts with phone numbers only, is there a way to do this with windows phone 7?

Implementing a security typed variant of Scala - which method is best?
|
Hio there Scala folks, I'm actually writing my master thesis and I have to implement a security typed language in Scala. So this means I have to add annotations to specify the special permissions levels for the variables and other programming constructs in Scala. The idea to add this comes from Jif (a real security typed language http://www.cs.cornell.edu/jif/) and FlowCaml (http://www.normalesup.org/~simonet/soft/flowcaml/). I still have to check how this languages add their security extensions.
I talked to my advisor and he suggested three possibilities how I can implement this feature in Scala:
1. source-to-source compiler (I don't think this is the best solution to write the things from the scratch because I will be busy with the parser and semantic and out of own experience I know that I don't have quite enough time to work on the main stuff)
2. type-checker plugin (I haven't wrote a plugin for compiler and think this just won't work on further versions of Scala because the compiler is still under development)
3. build a library in Scala (syntax are here simply free, so I can easily build something like this in a language I want => think this is like inventing a DSL and I believe that this is the best solution)
If you have another idea how to implement please let me know and if you have pros and cons for the methods mentioned above please let me know. I'm convinced that I will learn after this project of to program with pleasure in Scala (I'm familiar with Java and Ruby).
Greetings

Camera Troubles in Mathematica
|
I'm trying to animate a torus being cut by a plane, so that as the plane enters the torus the part in front of the plane disappears (the idea is to show the cross section). That much I can do, but I can't seem to get the camera to behave. I'd like everything to stay the same size and position, but despite setting `ViewVector`, `ViewAngle`, and `ViewVertical` the scene becomes smaller as the animation progresses. Note that I chose the settings pretty arbitrarily. I am baffled as to why the camera view changes with these three options fixed.
Here is the code (I produce the frames in a table, and then export them for the animation).
Table[Show[
ContourPlot3D[(1 - Sqrt[x^2 + (y + 1/2)^2])^2 + z^2 - 1/4 ==
0, {x, -2, 2}, {y, -2, 2 - 2 t}, {z, -2, 2}, Mesh -> False], (*The torus*)
ContourPlot3D[y == 2 - 2 t, {x, -2, 2}, {y, -2, 2}, {z, -2, 2},
Mesh -> False, ContourStyle -> {White, Opacity[.5]}], (*The plane*)
Axes -> False, Boxed -> True,
ViewVector -> {{5 Sqrt[6], 10 Sqrt[6], 5 Sqrt[6]}, {0, 0, 0}},
ViewAngle -> 3 Pi/50, ViewVertical -> {0, 0, 1}], {t, 0, 1, .5}]
And here is the result.
![Torus cross sections][1]
As you can see, the camera zooms out and seems to rotate slightly. Any idea how to fix this?

401 - Unauthorized Signature Invalid Intuit Partner Platform
|
When implementing OAuth in Intuit Anywhere, I get 401 Unauthorized (Signature Invalid) error while requesting request token.
I am sure that I have implemented my signature part correctly. I verified it with the result of an available tool as well.
I have included oauth_callback also in my signature generation apart from other oauth_* parameters.
Intuit Anywhere asks for certain URLs like application URL, disconnect URL, manage users URL. What is the significance of these URLs?
I am trying to develop a non ui application which would consume IPP's data services.
Please help.
Thanks in advance.

How do you pick neutral fonts for smartphone?
|
When you should make apps for smartphone on multi-platform - iOS, Android, WP7, ... -,
how do you make a decision what fonts will be used, and how to deploy it?
I thought using just embed truetype fonts or neutral font things, like in following article : http://www.bluetrainmobile.com/blog/choosing-fonts-for-your-mobile-website, but I don't have an idea which way will be better one.
Any suggestion?

Integrating command-line generated python .coverage files with PyDev
|
My build environment is configured to compile, run and create coverage file at the command line (using Ned Batchelder coverage.py tool).
I'm using Eclipse with PyDev as my editor, but for practical reasons, it's not possible/convenient for me to convert my whole build environment to Eclipse (and thus generate the coverage data directly from the IDE, as it's designed to do)
PyDev seems to be using the same coverage tool (or something very similar to it) to generate its coverage information, so I'm guessing there should be some way of integrating my external coverage files into Eclipse/PyDev.
Any idea on how to do this?

"No item exists at https://<internal_url>" after file upload when accessing the site externally
|
I have created a SharePoint 2010 site that is accessible both internally and externally. I have created alternate access mappings for `https://<internal_url>` (Extranet) and `https://<external_url>` (Internet). Requests, however, only come to the internal_url as there is a reverse proxy which translates the addresses.
This setup generally works fine as SharePoint uses relative URLs for most things. However, I'm experience some problematic bits, with the most annoying one being the following error after file upload:
No item exists at https://**<internal_path>**/Forms/EditForm.aspx?Mode=Upload&CheckInComment=&ID=5&RootFolder=/<path>&IsDlg=1. It may have been deleted or renamed by another user.
Web Parts Maintenance Page: If you have permission, you can use this page to temporarily close Web Parts or remove personal settings. For more information, contact your site administrator.
Troubleshoot issues with Microsoft SharePoint Foundation.
Note that the upload is successful but the popup window shows this error. It's not a critical issue but I know the user base, they are not very technical and we'll be facing constant support calls and lack of confidence in the solution.
Obviously, the confirmation tries to open the site at the internal URL (by which it has been requested any way, after the domain name translation at the reverse proxy), which is naturally unavailable externally.
I get this error only when Web Client service is started - when it's not in the same popup I get "Internet Explorer Cannot Open the Webpage" (although the logs may show the same error)
I'm also getting the same error when creating lists and document libraries
Can I make this work properly without messing with the general architecture of the DMZ infrastructure?

Why do you need webservices to access a database from Silverlight?
|
I am at the moment looking into several options to create a new app which can be accessed using the browser by multiple user in a closed intranet.
I thought about using Silverlight for its user-friendliness and its WPF design so close to the rich clients the future users are used to.
The project (of course) requires access to a database also within the intranet, hence I browsed the internet to see how data access was handled. I was surprised to see that you apparently _have_ to use web services to interact with data, as mentioned in [this SO post][1] which points [this tutorial][2] (one of many ways to use webservices).
Having already created various rich client within an intranet all interacting with database, I was surprised to be forced to use web services.
Indeed, I do understand the advantages of the web services; the security it provides, and all the other features of created a good DAL generally in software architecture. However, I can't see why you can't simply create (for example) a library containing the Linq to SQL classes and use this library as reference in the silverlight project to access data directly as you can do with classic rich client application. I understand that by doing that, you store the access data within the connection string of the app, but I can't see why it shouldn't work with a silverlight client.
So, two questions:
1. Do we actually _have_ to access data through web services?
2. If so, why is it different from the classic rich client approach?

What happens to Azure Virtual Machine (not VM role) on host failure?

I'm exploring leveraging the new virtual machine (not VM role) capability in Azure. The candidate application will not work (w/o significant rewrork) in a VM server farm to support high availability.
So my question is, what happens to the virtual machine on a host server failure? Does the virtual machine restart on a new host? Assuming that it does, what is a ballpark expectation for the restart to occur?

How to get a delphi application (that's running) to do something at a particular time/date
|
My application sits in the system tray when it's not being used.
The user can configure events to occur at particular schedule. For example they may way the task performed mon-fri at 5pm or every wednesday at 3pm or on the 16th of every month at 10am.
Assuming my delphi program is always running, it starts at boot-up, what is the best way in delphi to support the triggering of these scheduled events.
Obviously a TTimer can be used to schedule events based on elapsed time but they don't seem suited to this problem.
Cheers

Install ANT (and JAVA) on server
===
I am trying to install ANT (to build/compile Android apps) on a local Linux (Ubuntu) installation so that I can install it on a live server (work out the kinks first).
The following is a set of commands I have run to get to where I am:
> wget http://archive.apache.org/dist/ant/ant-current-src.zip
> /dest/folder
>
> unzip ant-current-src.zip
>
> wget http://download.oracle.com/otn-pub/java/jdk/6u25-b06/jdk-6u25-linux-x64.bin
> /dest/folder
>
> ./jdk-6u25-linux-x64.bin
>
> (backup PATH :P )
> export JAVA_HOME=jdk1.6.0_25 export
> PATH=$PATH:jdk1.6.0_25/bin
> wget http://voxel.dl.sourceforge.net/project/junit/junit/4.10/junit-4.10.jar
>
> cp junit-4.10.jar junit.jar
>
> rm junit-4.10.jar
>
> export CLASSPATH=$CLASSPATH:$JUNIT_HOME
