Which version of php add anonymous functions
|
In manual there is `create_function` function and you can pass result from that function to `array_map`, I thought that that is the only way to have something like anonymous functions and closures, but then I found that I can just put function like in javascript
array_map(function($a) {
return $a+1;
}, array(1, 2, 3, 4, 5));
In which version of php I can do this? I this was always there?

Creating a private MSMQ queue in a Microsoft Cluster via a script
|
We are migrating to Windows 2008 R2 Standard and will be using a Microsoft Clustering (active-passive) configuration. Our application is heavily dependent on MSMQ private queues and our install creates well over 100 private queues using the following C# code.
MessageQueue.Create(".\private$\myqueue", false);
Since the install is not running inside the context of the cluster, the queues are created on the local node and not in the cluster.
We then tried changing the code to:
MessageQueue.Create("MYCLUSTERNAME\private$\myqueue", false);
However, you can't create private queues on a different server (in this case the cluster server context) and you receive the error "Invalid queue path name".
My two questions are:
1) Is there a way I can run the install in the cluster's context so that when creating a private queue, it would actually be creating the queue in the cluster?
2) If not, what's the best approach on creating queues in the cluster via .NET? I've read some blogs where people create a middle-man Windows service that resides inside the cluster and then their install uses interprocess communication to tell the service which queues to create. That seems like a hack, but is doable if that turns out to be the only approach.

Dynamically change text on Twitter Bootstrap button whilst preserving icon?
|
How do I use javascript/jquery to change the text on a button in Twitter Bootstrap *without destroying the icon*?
So, this is my static markup:
<a class="btn" id="myButton" onclick="doSomething()"><i class="icon-ok"></i> Do it...</a>
I am able to change the icon, like this:
$('#myButton i:first-child').attr('class','icon icon-remove');
Which is fine, but for the love of all that is good I cannot find a way to set the button text without then wiping out the icon. Eg. if I do this:
$('#myButton').text('Some Remove Text');
I lose the icon element, so how can I access *just the text* and edit that, whilst preserving any child elements?

if ($num_results !="")

$row = mysql_fetch_array($result);
$email = stripslashes($row['email']);
$to = "Undisclosed Recipients";
$subject = strip_tags($_POST['subject']);

Configuring Haproxy with Tomcat to use context
|
I'm a newbie with haproxy and I'm trying to figure out how to do something which seems quite simple. I want to proxy a tomcat context.
For example http://bobsautomotive.com:8080/HelloWorld
Here is my haproxy config:
global
daemon
maxconn 256
log 127.0.0.1 local0
defaults
mode http
option httplog
option logasap
log global
timeout connect 5000ms
timeout client 50000ms
timeout server 50000ms
frontend http-in
bind *:80
default_backend servers
backend servers
balance roundrobin
option redispatch
option httpclose
option forwardfor
cookie JSESSIONID prefix
server one tomcat.bobsautomotive.com:8009 cookie tomcat1 check
stats uri /admin?stats
stats realm haproxy
stats scope .
This works fine to get to the Tomcat main page. But, If I try to change it to use a context like:
server one tomcat.bobsautomotive.com:8009/han cookie tomcat1 check
It won't work...
Any ideas?
Thanks

git: ignoring files in the origin
|
Is there a way to tell git to ignore a file that's stored in its origin? Since the files in question are in the upstream repository, just adding them to .gitignore or .git/info/exclude don't work.
**Background**:
My upstream repository has some generated files in it. Every time I do a local rebuild, these generated files are changed and differ from the committed version. The generated files are in the repository because many users don't have the software to generate them (and I don't have the power to change this). These generated files are never generated by hand and I never want to commit them to my git repository. I have a separate mechanism to push them to the master repository (and I have no control over this separate mechanism).
I'm using a private git repository for making edits to an upstream subversion repository. To do this, I have a git repository just for pulling commits from subversion. That git repository is periodically synced via a cronjob. I then have private git repositories that are clones of the upstream git repository. I want git to not bug me about the generated files. I'm happy with either of these two results: the files are no longer tracked by my local git repository (but they should be tracked by the one that syncs with svn), or git will silently update my generated files but it will never commit my changes and the files will never show up in the "Changed but not updated:" section of "git status".

how to use a sphinx to autogenerate documentation for that?
I want something like that
for each in settings module or INSTALLED_APPS (not starting with django.* or 3rdparty.*) give me a auto documentation output based on docstring
and autogen documentation and run tests before git commit
btw.
I tried doing .rst files by hand with
.. automodule:: module_name
:members:
but is sucks for such a big project,
and it does not works for settings
Is there an autogen method or something?
I am not tied to sphinx, is there a better solution for my problem?

cell programming guide

Can anyone give me link to some guide for cell programming. I'm searching for a long time. But all the resources I'm getting is not in the programming perspective. I need a document mainly focusing on Cell programming. I have enough basic architecture knowledge about CELL/BE architecture by studying a lot more pdfs online. So please tell me some resource that only concentrates on programming Cell.

Jquery Click Event Not Firing On First Click, but does on second click, why?
|
I've got a jquery code, which
$("a.reply").click(function() {
//code
});
When I click the link with .reply class the first time, nothing happens. The second time I click, the code inside the click function works.
The link is being inserted on the page using php from a mysql database. so it's not being inserted dynamically.
Why is this happening? Any solution?

Export HTML to EXCEL with PHP & jQuery
|
I would like to export an HTML `table` to a MS Excel document (and PDF ideally) as it is displayed on the HTML/CSS page. I read a lot of pages and topics about it (on stack mainly) but everyone seemed to be talking about exporting the table, and not formatting the final excel file.
I think it should work like this:
1. click on export button: call to jQuery
2. jQuery creates a pure HTML document from the HTML/CSS of the `table`
3. jQuery calls a PHP function/class ([http://phpexcel.codeplex.com][1] maybe) to generate the EXCEL file from the HTML code reformatted
4. With the headers sent by PHP, the browser asks the user to save/open the excel generated file
Would this work? If so do you know any jQuery plugins and PHP classes/functions to do so? If not, what is your idea about it?
<br />
Cheers,<br />
Nicolas.

Hello I have one c++ Programming assignment question.
I tried hard but somehow I am not getting.
Ques:
Assuming you are given a class “Engine” that has the “start()” method prototyped below, write a “Car” class with a “turnKey()” method that tells you whether the car started or not. The Car class should encapsulate the “Engine” class.
bool Engine::start();
Can anybody please help me?

How should I make my VBA code compatible with 64-bit Windows?
|
I have a VBA application developed in Excel 2007, and it contains the following code to allow access to the `ShellExecute` function from `Shell32.dll`:
Private Declare Function ShellExecute Lib "shell32.dll" Alias "ShellExecuteA" (ByVal hwnd As Long, ByVal lpOperation As String, ByVal lpFile As String, ByVal lpParameters As String, ByVal lpDirectory As String, ByVal nShowCmd As Long) As Long
Apparently the application will not compile on a 64-bit version of Windows (still using 32-bit Office 2007). I assume that this is because the `Declare` declaration needs updated.
I've read that Office 2010 introduced a new VBA runtime (VB7), and that this has some new keywords that can be used in the `Declare` statement to allow it to work properly on 64-bit Windows. VB7 also has new predefined compiler constants to support conditional compilation where either the old or new declaration will be used, depending on whether the application is running on 32 or 64-bit Windows.
However, since I'm stuck with Office 2007 I need an alternative solution. What are my options? (I'd really prefer not to have to release 2 separate versions of my application if at all possible).

Internal DNS configuration woes
|
Alright, I am going to state up front that this question may be too involved (amount of detail not complexity) for this medium. But I figured this was the best place to start.
I am attempting to setup a proof of concept project and my BIND configuration is my first big hurdle. I want to setup 3 DNS servers on 3 physical boxes. **None** of these boxes needs to resolve public addresses, this is internal **only**. I have read through how to setup internal roots in the (mostly) excellent DNS & BIND 5th ed book. But my translation of their example is not functional. All IP's are RFC 1918 non-routable.
Box 1 will be authoritative for addresses on the *box1.bogus* domain, and Box 2 will be authoritative for addresses on the *box2.bogus* domain. Box 3 will act as both an internal root and the TLD server for the domain *bogus*.
Current unresolved issues:
- I have a hints file on box 1 and 2 that contains a single **NS** record to the NS definition of the root zone. Additionally there is an **A** record that translates the NS to the ip of the root. if I `dig .` from box 1 I get an *authority* Section with the NS name, not an *answer* and *additional* record section. Therefore I am unable to actually resolve the IP of the root server from box 1.
- If I point my `/etc/resolv.conf` from box 1 directly at the root server and do a `dig box1.bogus` I get the ns.box1.bogus *answer* record and the translation in the *additional* section. However on the next iteration (when should get the A record) I get `dig: couldn't get address for ns.box1.bogus`
Obviously my configs are **not** correct. I don't see a way to attach them to this post, so if people want to walk through this step by step I will cut'n'paste them into a comment for this question. Otherwise I am open to taking this 'offline' with a "DNS guy" to figure out where I'm missing a '.' or have one too many!
I personally think the web could do with another internal root example that doesn't make use of the Movie-U example.

SQL query filtering by list of parameters
|
I have a query where I want to return all the rows which are associated with a list of values. You could write this very simply as:
select * from TableA where ColumnB in (1, 2, 3, 5)
I could generate this query in C# and execute it. However this is obviously less than ideal as it doesn't use parameters, it will suffer when trying to cache query plans and is obviously vulnerable to a SQL injection attack.
An alternative is to write this as:
select * from TableA where ColumnB = @value
This could be executed many times by C#, however this will result in N DB hits.
The only other alternative I can see is to create a temp table and join it that way, however I don't see this point of this as it would be more complex and suffer from the same limitations as the first option.
Which of these three methods is more efficient? Have I missed an alternative?

Replace all characters not in range (Java String)
|
How do you replace all of the characters in a string that do not fit a criteria. I'm having trouble specifically with the NOT operator.
Specifically, I'm trying to remove all characters that are not a digit, I've tried this so far:
String number = "703-463-9281";
String number2 = number.replaceAll("[0-9]!", ""); // produces: "703-463-9281" (no change)
String number3 = number.replaceAll("[0-9]", ""); // produces: "--"
String number4 = number.replaceAll("![0-9]", ""); // produces: "703-463-9281" (no change)
String number6 = number.replaceAll("^[0-9]", ""); // produces: "03-463-9281"

Auto-delete Max/Min from Array on creation
|
I have a script that gathers prices for a query from google api and spits out the min/max of the array created. See the below output. How do I get it to delete the value of the variables `$minval` and `$maxval` aka the minimum value and maximum value within the array?
<?php
$url = 'https://www.googleapis.com/shopping/search/v1/public/products?key=thekey&country=US&q=nintendo+wii';
$data = curl_init($url);
curl_setopt($data, CURLOPT_RETURNTRANSFER, TRUE);
curl_setopt($data, CURLOPT_HEADER, 0);
$product_result = curl_exec($data);
curl_close($data);
$arr = json_decode($product_result, true);
$prices = array();
foreach ($arr['items'] as $item)
{
if (isset($item['product']['inventories'][0]['price']) !== false)
{
$prices[] = $item['product']['inventories'][0]['price'];
}
}
echo '<pre>';
print_r($prices);
echo '<br /><br />';
$minval = min($prices);
$maxval = max($prices);
$avgofval = array_sum($prices) / count($prices) ;
echo "min is ". $minval . "<br>Max is ". $maxval . "<br />avg is " . $avgofval ;
echo '</pre>';
?>

Auto-delete Max/Min from Array on creation
===
I have a script that gathers prices for a query from google api and spits out the min/max of the array created. See the below output. How do I get it to delete the value of the variables `$minval` and `$maxval` aka the minimum value and maximum value within the array?
<?php
$url = 'https://www.googleapis.com/shopping/search/v1/public/products?key=thekey&country=US&q=nintendo+wii';
$data = curl_init($url);
curl_setopt($data, CURLOPT_RETURNTRANSFER, TRUE);
curl_setopt($data, CURLOPT_HEADER, 0);
$product_result = curl_exec($data);
curl_close($data);
$arr = json_decode($product_result, true);
$prices = array();
foreach ($arr['items'] as $item)
{
if (isset($item['product']['inventories'][0]['price']) !== false)
{
$prices[] = $item['product']['inventories'][0]['price'];
}
}
echo '<pre>';
print_r($prices);
echo '<br /><br />';
$minval = min($prices);
$maxval = max($prices);
$avgofval = array_sum($prices) / count($prices) ;
echo "min is ". $minval . "<br>Max is ". $maxval . "<br />avg is " . $avgofval ;
echo '</pre>';
?>
Output:

Switch from Web programming to data warehousing? Should I?
|
I was looking a report on internet that data warehousing is much lucrative and highly paid IT career. I am talking about technologies like abinitio etl datastage teradata. I work in ASP.net and sql server 05. Is it a good thought to move from web programming to data warehousing technologies. Since I would have no experience with data warehousing would I be eligible for a good pay? What technologies other than data warehousing are hot in terms to salary? I know, this may sound immature but I am planning to start my own business in future and would need capital for that.
Thanks

Using South migrations with Heroku.

I have successfully synced my database using south on the local server. I am having problems using south in Heroku. When I run
git add app/migrations/*
git commit -m 'adding new migrations'
heroku run python manage.py migrate app
I am getting a DatabaseError. Relation field already exists.
Any ideas why this isn't working? Also, do I need to run migrations locally and on the production environment each time one of my models change? Thanks for reading.

Lambda calculus representation of "if" structure and boolean "True"

I was wandering if anyone could tell me alternative lambda calculus representations for the "IF - THEN - ELSE" structure and the boolean "TRUE" besides the "classical" ones (i.e. for "if": \pca.pca ; and for true: \xy.x ).
I would really appreciate it if you could give me two different solutions.

Easy typing for non-english keyboards vim users

In English or US keyboards keys like `\` `/` `[` `]` are very easily typed with only one key stroke. Usually is not the same for non-english keyboards. Is there a way to achieve the same easiness of typing for these type of keyboards?
If it is a matter of `mapping keys` can you please put clear instructions to do it? (Spanish layout example is welcome)

Notepad++, Remember previous line folds on startup/file-open?

How do I get Notepad++ to remember previous line folds when I start the program or re-open a file?
Example:

-----------------------------------------
//Closed and re-opened file or Notepad++
[-] My code is no longer collapsed/folded, Notepad++ doesn't remember the previous file state

I would like it to behave just like Visual Studio does if possible.

StringBuffer going to append path for every method call
|
i am setting contextPath dynamically by using StringBuffer in java file. Here for every call the path is appending to StringBuffer Object based on number of calls. How can i run below code properly.
StringBuffer blankDeposit = new StringBuffer();
blankDeposit.setLength(0);
String rcp = request.getContextPath();
String create = "Create";
blankDeposit.append("<a href="+rcp+"/deposit/showBlankDepositSheet.do>"+create+"</a>"+"a blank Deposit Sheet.");
ActionHelper.formatInfoMessage(
mapping,
request,blankDeposit.toString());
Here `blankDeposit` should have the contextPath(/myapp)with the String. But i am getting a blank space instead of this. How can i do for this.
And the `blankDeposit` is appending the string by number of times i run. if i call five times then the above variable blankDeposit containing five times the appended string.

Pros of storing image resources inside a .bundle
|
I've been told that it's best practice to do so. I know the [Facebook iOS SDK][1] does this (look inside the `FBDialog.bundle` file). There are a few SO questions about [how to create them][2] as well. Apple also has a [Bundle Programming Guide][3].
But in a nutshell (and localization aside), are there significant pros of storing image resources inside a .bundle file?

Masking image on Shape
|
I'm not sure if the title explains what I want to do, but here goes:
I have drawn a circle with a shape. I have an photo.
What I want to be able to do is somehow make it so that only the parts of the photo that are within this circle are visible and what is outside is not visible. Therefore being able to drag the image to position how I want within the circle and therefore ending up with an image which is in the shape of a circle
Is this possible?

winsock gethostbyname fails
|
Visual Studio C++ 2008
I am using this code. However, gethostbyname always returns an error. Everything looks ok to me, so I don't understand why I am getting this error.
This is the code I am using up to getting the gethostbyname.
Any think obvious that I might be doing wrong?
int32_t sockfd;
/* struct definition */
struct sockaddr_in conn_addr;
/* gethostbyname for the function and struct definition */
struct hostent *server_hostname;
/* set address to connect to the local loopback */
char buffer[BUF_SIZE] = "127.0.0.1";
char data[BUF_SIZE] = {0};
/* getting hostname for the ip address stored in the buffer */
if((server_hostname = gethostbyname(buffer)) == NULL)
{
/* gethostbyname uses a special h_errno for error number */
fprintf(stderr, "gethostbyname [ %s ] [ %s ] [ %d ]\n", strerror(h_errno), __FUNCTION__, __LINE__);
return CS_FAILURE;
}
The error that gets returned is 'Unknown Error' which doesn't help too much.
Many thanks for any suggestions,

Code refactoring tools for C, Usable on GNU/Linux? FOSS prefrable
|
Variations of this question have been asked, but not specific to GNU/Linux and C. I use Komodo Edit as my usual Editor, but I'd actually prefer something that can be used from CLI.
I don't need C++ support, its fine if the tool can only handle plain C.
I really appreciate any direction, as I was unable to find anything.
I hope I'm not forced to 'roll' something myself.

Mastering technology like LINQ, WCF really necessary or is OOPS enough?
|
I am a C# developer.
My observation in the IT industry as a C# developer is that, technology is always changing or being updated by Microsoft like LINQ, WCF, and WPF etc.
OOPS has been the fundamental for all kinds of developments that we see today in any language.
My question is,
1. Is it good if I am a decent programmer in OOPS but not mastering any specific technology?
2. As a winforms developer, is it necessary to know C++ with C# for better job perspective?
Thanks for your support.

Calendar button behaving badly
|
This is a beginner level task. I am trying to implement a calendar widget in django using the following
example: `http://djangosnippets.org/snippets/1629/`
I am putting this calendar inside a form with that already has a submit button.
The problem I am having is that my calendar button submits my form rather than
displaying the calendar widget. The calendar icon and button display properly and I can
see that it has the right code from firebug, but that's about it.
What I really need is an EASY calendar to go along with a ModelForm. I don't
care so much about using the JSCal2 as much as making any calendar work.
Why is my calbutton submitting my form? How do I make it display the widget
and work properly? Any other suggestions to easily get a working calendar?
-------------widgets.py ---------------------
calbtn = u"""<input id="calendar-inputField" /><button id="calendar-trigger"> <img src="%simages/calbutton.gif" alt="calendar" id="%s_btn"

Grails. Select tag
|
I am using 2 select tags. Their content can be modified inside the web page(via javascript).
By default grails will take only the selected option (or all selected options if multiple is enabled) and pass it to the controller.
How could I pass to the controller all the available rows from a select box ?

Hide action bar menu items from invisible fragment
|
I use 3 FrameLayouts in my activity view xml into which I dynamically insert different fragments. Many of these fragments contribute ActionBar MenuItems. Now I have a situation where I hide a FrameLayout (set visibility to View.GONE) and therefore the Fragment in it becomes invisible. However it still contributes the menu item since the fragment does not to seem to be paused or anything so I cant seem to call a method that actively hides the action bar item.
As a solution I now just insert a fragment into the FrameLayout that has no menu item when I switch the FrameLayout to invisible. While that works it feels like a hack to me. What is the proper way to hide any action bar menu items? What states does the fragment go into if I just hide the layout it is in?
I am doing all this with the compatibility library r6 in case that matters.

C++: Array index as reference to instance
|
I have to do some code for the university which gives me a headache. Some of you brilliant minds might help me out :D
I'm asked to create a table in which studentdata is stored (like age and name), and everyone has a unique number for identifying. Though the number shall be stored in an array which will be searched by an algorhithm later on to find specific students.
Now my problem: How do I link the number in the array with the proper instance of class student? Given hint points towards the array index as reference, but I have no clue at all how to implement that.
Thanks in advance :)

Higher-level languages for stored procedures
|
I'm getting increasingly frustrated with the limitations and verbosity required to actually commit some business logic to stored procedures, using languages such as Transact-SQL or PL/SQL. I would love to convert some current databases to Oracle and take advantage of its support for Java stored procedures, but that option is not available at the moment.
What other alternatives would you recommend in the way of databases that support high level stored procedure languages?

How to avoid certain formatting with PAR?
|
PAR does i.m.o. a much better formatting as Vim default formatter.
But sometimes PAR does't work very well.
p.e.
<pre>this is a test this is a test this is a test.
this is my text this is my text this is my text.</pre>
formatting with par 44 becomes:
<pre>this is a test this is a test this is a t.
this is tes my text this is my text this t.
this is is my tex t.</pre>
Is there a way to resolve this kind of formattion?

I believe i have to do something under "private DropListener mDropListener" to save the change and the i need to read the new item position onCreate?

I believe i have to do something under "private DropListener mDropListener" to save the change and the i need to read the new item position onCreate?

How to express current date in MQL Freebase Query?

How to get to /public outside WEB-INF when using Spring MVC

i'm having hard time uploading images to public folder.The public folder is a sibbling of WEB-INF inside Webapp folder.
attempts like
`this.getClass().getResource("/images/16x16").toString()` returns null pointer exception.
i've added image folder as resource
<mvc:resources mapping="/images/**" location="/public/images/" />
is there a way to achieve that? thanks for reading this

Control Best Practices
|
Is it better to only create an instance variable for a control or an instance variable with a property in objective c/xcode?
If you are to create a property is it best to make it atomic or nonatomic (for a control).
For example, what is the best practice for doing the following:
@interface blah
{
UILabel *label;
}
@property (nonatomic, retain) IBOutlet UILabel *label;
OR
@interface blah
{
IBOutlet UILabel *label;
}
OR
@interface blah
{
UILabel *label;
}
@property (retain) IBOutlet UILabel *label;
Then when I dealloc is it best to do:
[self.label release]
or
[label release]

Making a better Makefile
|
so I learned what a Makefile was some time ago, created a template Makefile and all I do is copy and alter the same file for every program I'm doing. I changed it a few times, but it's still a very crude Makefile. How should I improve it? This is an example of my current version:
CC = g++
CFLAGS = -std=gnu++0x -m64 -O3 -Wall
IFLAGS = -I/usr/include/igraph
LFLAGS = -ligraph -lgsl -lgslcblas -lm
DFLAGS = -g -pg
# make all
all: run test
# make a fresh compilation from scratch
fresh: clean test
#makes the final executable binary
run: main.o foo1.o foo2.o
$(CC) $(CFLAGS) $(LFLAGS) $^ -o $@
#makes the test executable with debugging and profiling tags
test: test.o foo1.o foo2.o
$(CC) $(DFLAGS) $(CFLAGS) $(LFLAGS) $^ -o $@
#makes teste.o
teste.o: teste.cpp
$(CC) $(CFLAGS) $(IFLAGS) -c $^ -o $@
#makes main.o
main.o: main.cpp
$(CC) $(CFLAGS) $(IFLAGS) -c $^ -o $@
#file foo1
foo1.o: foo1.cpp
$(CC) $(CFLAGS) $(IFLAGS) -c $^ -o $@
#file foo2
foo2.o: foo2.cpp
$(CC) $(CFLAGS) $(IFLAGS) -c $^ -o $@
clean: clean-test clean-o clean-annoying
clean-test:
rm test-rfv
clean-o:
rm *.o -rfv
clean-annoying:
rm *~ -rfv
Just by visually comparing with other makefiles I saw around in the web, this seems to be not a very bright Makefile. I don't know how they work, but I can see there's significantly less boilerplate and more generic code in them.
Can this can be made better, safer, and easier to particularize for each project?

If you've had a good experience with a book or two that covers these topics could you please share them?

BigDecimal from Double incorrect value?

I am trying to make a BigDecimal from a string. Don't ask me why, I just need it! This is my code:
Double theDouble = new Double(".3");
System.out.println("The Double: " + theDouble.toString());
BigDecimal theBigDecimal = new BigDecimal(theDouble);
System.out.println("The Big: " + theBigDecimal.toString());
This is the output I get?
The Double: 0.3
The Big: 0.299999999999999988897769753748434595763683319091796875
Any ideas?

Nginx name based virtual hosting default site
|
I am trying to figure out how to configure my Nginx virtual host files. Here's what I have.
In my DNS (at the registrar), I direct *.sitename.com to a single IP address, say 123.456.789.012
Now, on the server itself, I am running Nginx, with virtual hosts.
I have serveral virtual hosts, say
www.sitename.com
demo1.sitename.com
...etc...
demo5.sitename.com
The problem I am trying to solve, is that I want to redirect all requests for subdomains not defined explicitly as virtual hosts, to the www.sitename.com.
So, if someone requests someundefined.sitename.com, I want to redirect this request to www.sitename.com
At the moment though, Nginx just redirects them to demo1.sitename.com ... I cannot figure out how to keep all the other virtual hosts working, whilst redirecting all the unnamed ones to the main site.

What is the best way to implement notification in a C# web application?
|
What is the best way to implement notification in a C# web application? If this was an EAI BPEL application, I would be using the notification feature within the BPEL specifications to emit events at key tasks I want to monitor. Since this is a C# web application, what are the architectural options? Should I drop messages via pub/sub using NServiceBus at points I want to monitor or should I use .Net event handling to attach to methods I care about or a mixture of both or is there an option I'm not aware of. The case I'm trying to optimize is the least amount of code with the maximum flexibility and scalability.

multiple threads in Intel core 2, i-series of processors?
|
Will the performance be improved more than 25% if the a singled threaded task (pure computation) is split into multiple threads in Intel core 2, i-series of processors ?
Note - As I know One core executes one thread at a time
The hardware is changed from 2000 to 2012, but the style of programming is not changed that much
Scenarios1 - Just one application is running which is very ideal case
Scenario 2 - Multiple applications are running which is our day to day usage
Thanks in advance

How to use two TSplitter with different aligns (Horizontal and Vertical) ?
|
I have a form with three sections, and I want to allow the users to resize them as they please
There is one section on the left (which take the whole height) and one on the right that is again cut in two vertically. See below:
11|22<br />
11|---<br />
11|33<br />
Using one splitter is quite easy:
<pre>Component1.align := alLeft
Splitter1.align := alLeft
Component2.align := alClient</pre>
Now, starting with that I have absolutely no idea how to get a vertical splitter working. If I set my second splitter to alTop or alBottom, it does all the way to the top/bottom and not only in the right half.
One possible solution is to use a panel as my right side and then use a splitter INSIDE this pannel for vertical splitting but it doesn't really feels like the right way.
Thanks

How to collect data from social networks using C# or other OOP?
|
I'm having a reasearch called "Data Mining on Social Networks". In the first part I used user ready programs like NodeXL and Netminer. Because of the programs limitations the reasearchs mining part lacked. So I need to have a more sophisticated data mining reasearch using object oriented programs and I am asking how.

Postgresql breaking rails querying functionality
|
I have a rails app that was working fine with sqlite but upon switching over to postgre I'm having an issue with this query:
User.find(2).ratings.query
Querying for just one user works, e.g.
User.find(1)
produces
SELECT "users".* FROM "users" WHERE "users"."id" = $1 LIMIT 1 [["id", 1]]
however if I append ratings like so:
User.find(1).ratings
produces
User Load (1.4ms) SELECT "users".* FROM "users" WHERE "users"."id" = $1 LIMIT 1 [["id", 1]]
Rating Load (0.9ms) SELECT "ratings".* FROM "ratings" WHERE "ratings"."user_id" = 1
PG::Error: ERROR: operator does not exist: character varying = integer
LINE 1: ...CT "ratings".* FROM "ratings" WHERE "ratings"."user_id" = 1
^
HINT: No operator matches the given name and argument type(s). You might need to add explicit type casts.
: SELECT "ratings".* FROM "ratings" WHERE "ratings"."user_id" = 1
ActiveRecord::StatementInvalid: PG::Error: ERROR: operator does not exist: character varying = integer
LINE 1: ...CT "ratings".* FROM "ratings" WHERE "ratings"."user_id" = 1
^
Whether a pass the :id as an int or string it still produces the above error. The models are set up so :ratings belongs_to User which has_many :ratings. Any ideas? Thanks in advance.

How to implement a log in system using CI sessions that is stored in databases

I tried adding 2 more columns(`is_logged`, `user_id`), but my PHP script just assign it to `NULL`,
Other columns are assigned automatically by Codeigniter.
this is my PHP script:
$user_data = array(

Jquery mobile orientation change returns opposite value
|
I am currently working on a mobile website using jquery mobile and I encountered problem in detecting orientation change. My mobile website detects the orientation as "landscape" when in portrait mode and vice versa when testing on my Samsung Galaxy. However, working properly on iphone n HTC Desire. I did find in some forums that described that as Android bug and someone used setTimeOut to tackle it. But I can't solve the problem using that. Not sure if it's my syntax error or not. Can someone kindly enlighten me? Thanks in advance.
Sample code will be much appreciated.
Here is my current code:
$(document).ready(function() {
$(window).bind("orientationchange", function (event) {
setTimeout(detectOri(event),100);
});
function detectOri(event)
{
alert(event.orientation);
if(event.orientation == 'portrait')
{
//load portrait mode page
}
else if(event.orientation == 'landscape')
{
//load landscape mode page
}
}
});

WPF - How to make Style.Triggers trigger a different named style to be applied
|
Lets say I have the below:
<Style TargetType="{x:Type TextBox}">
<Setter Property="BorderThickness" Value="1" />
<Setter Property="BorderBrush" Value="Gray" />
<Style.Triggers>
<Trigger Property="IsFocused" Value="true">
<Setter Property="BorderBrush" Value="Green" />
<Setter Property="BorderThickness" Value="2" />
</Trigger>
</Style.Triggers>
</Style>
This works fine and there is nothing too much wrong here, but it is a fairly simple case. What happens if I want to have the IsFocused style state listed as a exsplicit style how do reference that style as being the IsFocused style, i.e.
<Style x:key="ActiveStyle" TargetType="{x:Type TextBox}">
<Setter Property="BorderBrush" Value="Green" />
<Setter Property="BorderThickness" Value="2" />
</Style>
<Style TargetType="{x:Type TextBox}">
<Setter Property="BorderThickness" Value="1" />
<Setter Property="BorderBrush" Value="Gray" />
<Style.Triggers>
<Trigger Property="IsFocused" Value="true">
-- Here I want to reference ActiveStyle and not copy the copy the setters
</Trigger>
</Style.Triggers>
</Style>

css not working in table "td" , but it works for "th"....what's going on?
|
I've been coding a webapp for some time now and all the layout, css was working fine. Some time in the last week or so I made some kind of a change that I absolutely have no idea what I changed that is causing this problem and I've tried reversing the code with no luck. I have figured out however that the problem goes away if I use a `<th>` in place of a `<td>` in my tables. Problem is there are thousands of lines of code that have to be modified and I'm using the tables to display my columnar data read out of the db. If I can avoid having to change the `<td>` tags to `<th>` I will be really happy.
I use css to style the column names. Can anyone explain why the following now fails when it has worked fine for 8 months now. I know the code obviously changed somewhere, but I'm clueless where to look....perhaps your explanation will give me an idea where to look in my code.
This used to work but now displays only grey text in the FIELD_name area:
`<td class="FIELD_name">Field Name:</td><td class="FIELD_text">small grey text here"</td>`
If I do this I get the proper display (using "th" instead of "td"):
`<th class="FIELD_name">Field Name:</th><th class="FIELD_text">small grey text here"</th>`
or if I use a span tag like this it also works:
`<td><span class="FIELD_name">Field Name:</span></td><td class="FIELD_text">small grey text here"</td>`
Here's the CSS:
.FIELD_name {
font-family: Tahoma;
font-size: 11px;
font-style: normal;
color: #135386;
font-weight: bold;
}
.FIELD_text {
font-family: "Times New Roman", Times, serif;
font-size: 12px;
font-style: normal;
color: #666666;
font-weight: bold;
}
I'm hoping it's just a simple code fix somewhere...your help is appreciated. thanks.

NServiceBus: How to stop distributor acting as a processing bottleneck (reduces rate 65%)
|
We have an event processing system that will process events sent directly from the source to handler process at 200 eps (events per second). The queues and message sends are transactional. Adding the NSB distributor between the event generator and the handler process reduces this rate from 200 eps to 70 eps. The disk usage and CPU on the distributor box become significantly higher as well.
Seen with commercial build of NServiceBus, version 2.6.0.1505.
Has anyone else seen this behaviour or have any advice?

PYTHON- Given a starting word, which sequence of letters will allow you to maximize the number of valid words that can be spelled
|
I was inspired to write a program based on the card game Scrabble Slam! I'm new to algorithms, however, and can't think of an efficient way of solving this problem:
You start with a string containing an English-valid 4 letter word. You can place one letter on that word at a time such that by placing the letter you form a new dictionary-valid word. The letters that you have are equal to the letters in the alphabet.
For example if the starting word was "cart", this could be a valid sequence of moves:
sand --> sane --> sine --> line --> lins --> pins --> fins , etc.
The goal is to maximize the number of words in a sequence by using as many letters of the alphabet (without using a letter more than once).
My algorithm can't find the longest sequence, just a guess at what the longest might be.
First, it gets a list of all words that can be formed by changing one letter of the starting word. That list is called 'adjacentList.' It then looks through all the words in adjacentList and finds which of those words have the most adjacent words. Whichever word has the most adjacentWords, it chooses to turn the starting word into.
For example, the word sane can be turned in 28 other words, the word sine can be turned into 27 other words, the word line can be turned into 30 other words-- each one of these choices was made to maximize the likelihood that more and more words could be spelled.
##Returns a list of all adjacent words. Lists contain tuples of the adjacent word and the letter that
##makes the difference between those two words.
def adjacentWords(userWord):
adjacentList, exactMatches, wrongMatches = list(), list(), str()
for dictWords in allWords:
for a,b in zip(userWord, dictWords):
if a==b: exactMatches.append(a)
else: wrongMatches = b
if len(exactMatches) == 3:
adjacentList.append((dictWords, wrongMatches))
exactMatches, wrongMatches = list(), list()
return adjacentList
#return [dictWords for dictWords in allWords if len([0 for a,b in zip(userWord, dictWords) if a==b]) == 3]
def adjacentLength(content):
return (len(adjacentWords(content[0])), content[0], content[1])
#Find a word that can be turned into the most other words by changing one letter
def maxLength(adjacentList, startingLetters):
return max(adjacentLength(content) for content in adjacentList if content[1] in startingLetters)
def main():
startingWord = "sand"
startingLetters = "a, b, c, d, e, f, g, h, i, j, k, l, m, n, o, p, q, r, s, t, u, v, w, x, y, z".replace(" ", "").split(',')
existingWords = list()
while True:
adjacentList = adjacentWords(startingWord)
letterChoice = maxLength(adjacentList, startingLetters)
if letterChoice[1] not in existingWords:
print "Going to use letter: "+ str(letterChoice[2]) + " to spell the word "+ str(letterChoice[1]) + " with "+ str(letterChoice[0]) + " possibilities."
existingWords.append(letterChoice[1])
startingLetters.remove(str(letterChoice[2]))
startingWord = letterChoice[1]

You start with a string containing an English-valid 4 letter word. You can place one letter on that word at a time such that by placing the letter you form a new dictionary-valid word. The letters that you have are equal to the letters in the alphabet.
For example if the starting word was "cart", this could be a valid sequence of moves:
sand --> sane --> sine --> line --> lins --> pins --> fins , etc.
The goal is to maximize the number of words in a sequence by using as many letters of the alphabet (without using a letter more than once).
My algorithm can't find the longest sequence, just a guess at what the longest might be.
First, it gets a list of all words that can be formed by changing one letter of the starting word. That list is called 'adjacentList.' It then looks through all the words in adjacentList and finds which of those words have the most adjacent words. Whichever word has the most adjacentWords, it chooses to turn the starting word into.
For example, the word sane can be turned in 28 other words, the word sine can be turned into 27 other words, the word line can be turned into 30 other words-- each one of these choices was made to maximize the likelihood that more and more words could be spelled.
##Returns a list of all adjacent words. Lists contain tuples of the adjacent word and the letter that
##makes the difference between those two words.
def adjacentWords(userWord):
adjacentList, exactMatches, wrongMatches = list(), list(), str()
for dictWords in allWords:
for a,b in zip(userWord, dictWords):
if a==b: exactMatches.append(a)
else: wrongMatches = b
if len(exactMatches) == 3:
adjacentList.append((dictWords, wrongMatches))
exactMatches, wrongMatches = list(), list()
return adjacentList
#return [dictWords for dictWords in allWords if len([0 for a,b in zip(userWord, dictWords) if a==b]) == 3]
def adjacentLength(content):
return (len(adjacentWords(content[0])), content[0], content[1])
#Find a word that can be turned into the most other words by changing one letter
def maxLength(adjacentList, startingLetters):
return max(adjacentLength(content) for content in adjacentList if content[1] in startingLetters)
def main():
startingWord = "sand"
startingLetters = "a, b, c, d, e, f, g, h, i, j, k, l, m, n, o, p, q, r, s, t, u, v, w, x, y, z".replace(" ", "").split(',')
existingWords = list()
while True:
adjacentList = adjacentWords(startingWord)
letterChoice = maxLength(adjacentList, startingLetters)
if letterChoice[1] not in existingWords:
print "Going to use letter: "+ str(letterChoice[2]) + " to spell the word "+ str(letterChoice[1]) + " with "+ str(letterChoice[0]) + " possibilities."
existingWords.append(letterChoice[1])
startingLetters.remove(str(letterChoice[2]))
startingWord = letterChoice[1]
main()

Serial <> Ethernet converter and SerialPort.Write()
|
I'm trying to achieve maximum throughput on a serial port. I believe my C# code is causing a buffer overrun condition. SerialPort.Write() is usually a blocking method.
The problem is the unit/driver doing the Ethernet to Serial conversion doesn't block for the duration it takes for it to transmit the message. It doesn't appear to block at at all. Until it ends up blocking forever once too much data is written to it too fast. Then the SerialPort needs to be disposed before it will work again. Another issue is BytesToWrite always == 0 directly after thw write. Driver???
So, how do I get around this issue?
I tried doing a Sleep directly after the write for the duration it would take send the message out, but it doesn't work.
com.Write(buffer, 0, length);
double sleepTime = ((length + 1) * .000572916667) * 1000; //11 bits, 19.2K baud
Thread.Sleep((int) sleepTime);
I realize there may be some delay between when the unit receives the message and when it sends it out the COM port. Perhaps this is the reason why the driver does not block the .Write call?
I could wait for the message to be ack'd by the node. Problem is I'm dealing with thousands of nodes and some messages are broadcast globally. It is not feasible to wait for everyone to ack. What to do?
Any ideas?

Accessing the array typed mustache partial
|
I am using Mustache with PHP for my view layer. And I want to use an easy&dirty workaround for i18n. So I'm just curious;
I have a predefined partial set as;
$messages = array();
$messages['welcome'] = 'Hello World to you {{user.getName}}';
$messages['put'] = 'you put a {{variable}} here.'; //and etc
And the main partial set includes the messages as;
$partials['messages'] = $messages;
And of course this is rendered with a silly line of;
$mustache->render($template, $parameters, $partials);
I want to make use of the messages easily in my template. Such as;
{{>#messages}}{{>put}}{{>/messages}}
I don't want to mix the messages and partials because there are some minor conflicts.
Is there any way to reach those 'nested' partials?

Best database for inserting records
|
What would be the best DB for Inserting records at a very high rate.
The DB will have only one table and the Application is very simple. Insert a row into the DB and commit it but the insertion rate will be very high.
Targetting about 5000 Row Insert per second.
Any of the very expensive DB's like Oracle\SQLServer are out of option.
Also what are the technologies for taking a DB Backup and will it be possible to create one DB from the older backed up DB's ?

Should programmers have to be part of a professional body to practice?
|
Accountants, lawyers, doctors (and many other professions) have respected professional bodies that are responsible for awarding chartered status to the members. Through this mechanism, they gain trust and respect and can demonstrate that they adhere to a code of standards and ethics, and maintain their skills to keep them current.
Programming has a similarly large body of knowledge and a similar need for study and continual development. It is far younger a discipline than any of the examples quoted, but is of growing consequince to business, the economy, and most areas of life.
Will programming eventually become as respected a profession with a powerful professional body? (Lawyer and accountant jokes aside!) Shold we be aiming for this?

check return of sql command in c#

i want to check if my query returns anv value or not and write the remaining logic accordingly.
SqlCommand myCommand = new SqlCommand("Select * from phc.userbase where [user]='@Username' and [password]='@password'", myConnection);
I want to know this command returns null or not. I tried
myReader = myCommand.ExecuteReader();
bool rd = myReader.Read();
if rd==false
but i can't get it working.any ideas?
here are my prameters .
SqlParameter myParam = new SqlParameter("@Username", SqlDbType.VarChar, 25);
myParam.Value = usr;
SqlParameter myParam2 = new SqlParameter("@password", SqlDbType.VarChar, 25);
