freeing the popup twice crashes applcation
In my execute block that gets called with a button click, I create a popup
menu to appear where the button was clicked. It current appears properly,
with a few items with one of them having a couple sub items. When this
that runs once then calls the destructor, it is fine. But if I execute it
twice (show the popup and click an item twice) then destruct, the
application crashes. I think it is because I'm not freeing the popup
correctly (which is declared as a private property).
procedure TPlugIn.Execute(AParameters : WideString);
var
i: Integer;
pnt: TPoint;
begin
GetCursorPos(pnt);
FPopup := TPopupMenu.Create(nil);
FPopup.OwnerDraw:=True;
FPopup.AutoHotkeys := maManual;
//SQL Upgrade
Item := TMenuItem.Create(FPopup);
Item.Caption := 'Database Install/Upgrade';
Item.OnClick := ShowItemCaption;
FPopup.Items.Add(Item);
//Language Folder
Item := TMenuItem.Create(FPopup);
Item.Caption := 'Language Folder';
Item.OnClick := ShowItemCaption;
FPopup.Items.Add(Item);
//Machines
Item := TMenuItem.Create(FPopup);
Item.Caption := 'Machines';
MachineItem := TMenuItem.Create(FPopup);
MachineItem.Caption := 'Sample Machine 1';
MachineItem.OnClick := ShowItemCaption;
Item.Add(MachineItem);
MachineItem := TMenuItem.Create(FPopup);
MachineItem.Caption := 'Sample Machine 2';
MachineItem.OnClick := ShowItemCaption;
Item.Add(MachineItem);
FPopup.Items.Add(Item);
Self.FPopup := FPopup;
FPopup.Popup(pnt.X, pnt.Y);
end;
In the ShowItemCaption procedure I just show the caption of that sender
object. I haven't coded specific events yet. If it free the popup in the
execute procedure, the popup doesn't appear anymore.
destructor TPlugIn.Destroy;
begin
inherited;
FPopup.Free;
//ShowMessage('freed');
end;

IList Property stays null even when member is instantiated
IList Property stays null even when member is instantiated
I am having trouble using an IList property which always seems to return
null, even though the member is is getting is instantiated:
private List<ModelRootEntity> _validTargets = new
List<ModelRootEntity>();
public IList<IModelRootEntity> ValidTargets
{
get
{
return _validTargets as IList<IModelRootEntity>;
}
protected internal set
{
if (value == null)
_validTargets.Clear();
else
_validTargets = value as List<ModelRootEntity>;
}
}
ModelRootEntity implements IModelRootEntity. I watched both values during
debugging, whilst the member shows a positive count, the property stays
null.
I also tried raising an exception within the property getter to throw if
the counts of _validTargets and _validTargets as List<ModelRootEntity> are
different, but it never threw.
Found question [Dictionary properties are always null despite dictionaries
being instantiated, which seems similar, however in my case this seems to
happen regardless of serialization.
Any ideas?

store php multidimensional array in localstorage
store php multidimensional array in localstorage
I'm building a site where a user can use the site and input data. However
to save their data, they need to log into my site (using facebook
connect). The data that they input is stored in a php multidimensional
array with the following structure:
$order = array();
$order[] = array('rank'=>'1', 'day'=>'Tues'); // This $order[] has input
inputted several times by the user
// I haven't included all the code because it's big, all that's really
needed is to see the structure of $order
My question is, how do I convert the php multidimensional array into
javascript and then how do I store it onto localStorage using
localStorage.setItem() so that once they've logged in with facebook
connect I can use that data? Is this the best way of going about it or
should I be doing something else?
<?php
require_once 'src/facebook.php';
$order = array();
$order[] = array('rank'=>$column, 'day'=>$day);
$loginUrl = $facebook->getLoginUrl(array('scope'=>'user_about_me,email'));
?>

function fblogin() {
var fk = "<?php echo $loginUrl; ?>";
// What do I do here to convert $order into javascript?

NumPy : array methods and functions not working
NumPy : array methods and functions not working
I have a problem regarding NumPy arrays.
I cannot get array methods like .T or functions like numpy.concatenate to
work with arrays I create:
>>> a=np.array([1,2,3])
>>> a
array([1, 2, 3])
>>> a.T
array([1, 2, 3])
>>> np.concatenate((a,a),axis=0)
array([1, 2, 3, 1, 2, 3])
>>> np.concatenate((a,a),axis=1)
array([1, 2, 3, 1, 2, 3])
>>>
However when I create an array using bult-in functions like rand
everything is fine
>>> a=np.random.rand(1,4)
>>> a.T
array([[ 0.75973189],
[ 0.23873578],
[ 0.6422108 ],
[ 0.47079987]])
>>> np.concatenate((a,a),axis=0)
array([[ 0.92191111, 0.50662157, 0.75663621, 0.65802565],
[ 0.92191111, 0.50662157, 0.75663621, 0.65802565]])
Do you think it has to do with element types (int32 vs float64) ?
I anm running python 2.7 on windows 7
Any help would be greatly appreciated.
Thanks !

What is the best cloud hosting solution for nodejs and mongodb application?
What is the best cloud hosting solution for nodejs and mongodb application?
I am working on a new application which uses nodejs and mongodb. I am new
to both of these. I have earlier worked on AWS and simple unix servers.
But I need a solution like heroku which can be scaled with least efforts.
Please give some feedback regarding that.
I have googled a bit and I liked https://modulus.io/ . Its scalable and
cheap.
Heroku + Mongolab seems costly.
Also I am not aware of what issues I am going to face.
Pardon me if you find this question unsuitable for stackoverflow.

How can you secure a JavaScript application's API calls?
How can you secure a JavaScript application's API calls?
I have a JavaScript application.
It's built with jQuery.
It uses $.get() to pull JSON data from a server, and uses the data to load
a puzzle.
I want to distribute the JavaScript application to clients, and make it
easy for them to install.
I'd like it to simply give them a JavaScript block they can drop into
their page, and it will interact with my API.
I'm not passing sensitive data, any my API is protecting the database from
SQL injection, etc.
I just want to try to prevent unauthorized use of my API, and I can't
think of a way to do that with JavaScript, since anyone with a DOM
inspector can scrape any credentials from any variables or can monitor any
server traffic POST or GET data...
Would it be possible to authenticate the referrer on the other side?
I know that's not bulletproof, but it's not sensitive data. I just want to
reduce the unauthorized use as much as possible..
Any ideas?

Excel VBA: How to set range to variable?
Excel VBA: How to set range to variable?
I'm trying to save a range from another sheet to a variable and then
compare it to a cell. I have this code:
Function collectUtfall(A1 As String, Ax As String)
Dim rng As Variant
Dim sum as Integer
sum = 0
Set rng = Sheets("Utfall").Range("N2").Value <------- This line
If rng = Ax Then
sum = sum + 10
Else: sum = 33
End If
collectUtfall = sum
End Function
The problem is that it's not acting the way I hoped. I get #Value error,
and I have narrowed it down to the line marked in the code. If I remove
that line I don't get the error but of course the result is only 0.
I have tried to dim rng As Range also, doesn't work.

How to post dynamic fields in IE9
How to post dynamic fields in IE9
I have a form in which users can fill static fields. Below them a button
allows to add dynamically new fields :
<form action="url" method="POST">
<table class="table" id="mytable">
<thead>
<tr>
<th>Foo</th>
<th>Bar</th>
</tr>
</thead>
<tbody>
</tbody>
</table>
<button id="new-field">Add new fields</button>
</form>
Here is my JS code :
$('#new-field').click(function(e) {
e.preventDefault();
var i = $('#mytable tbody tr').length + 1;
$('<tr><td><input type="text" name="newfield['+ i
+']['foo']"></td><td><input type="text" name="newfield['+ i
+'][bar]]"></tr>').appendTo($('#mytable tbody'));
});
New fields are displayed correctly, but when I post the form (via a submit
button), new fields are not considered on IE9... It works on Firefox and
Chrome.
Apparently here is a solution : Dynamically added form elements are not
POSTED in IE 9 But I can't use the compatibility mode for my project.
Have you got any solution please ?

How to detect hashed password length?
How to detect hashed password length?
I've started learning of password hashing. And I wonder how to detect
hashed password length? Right now I'm experimenting with sha512 and one of
the question is how to get user typed password length? Or is it impossible
and I should validate user typed password length (e.g. if it is more than
8 characters) with javascript before sending a password to server? Could
anybody explain me or suggest some learning material?

selecting two diffferent data from different table and display the value
i have two tables tbl_product and tbl_sales. my problem is that how
can i get the data from two different table and display it
horizontally and sum the "total" and "discount" from tbl_rsales. for
example
the ff data in my tbl_products are
id|pcode|pdesc |
1 |1000 |wire |
2 |1443 |capactor |
and the ff data in my tbl_sales are
id|total|discount| pcode |
1 |1000 |10 | 1000 |
2 |2000 |20 | 1443 |
3 |1000 |10 | 1000 |
4 |1000 |20 | 1443 |
the expected output must be something like this. how can i select it from
two different table?
id | pcode | pdesc | total | discount |
1 | 1000 | wire | 2000 | 20 |
2 | 1443 | capacitor | 3000 | 40 |

How to print from MVC4 controller from server
How to print from MVC4 controller from server
Code below is used to print from ASP .NET MVC4 application to Samsung
ML-331x Series printer connected to IP address in LAN and shared in server
as Samsung ML-331x Series
Nothing is printed. Execution stops at doc.Print() line. Every controller
call adds new unfinished job:
Those jobs are never finished, only iisreset clears them.
Server is Windows 2003 + IIS It worked in MVC2 .NET 3.5 application.
ForteSSL VPN was installed in server and application was upgraded to MVC3
and .NET 4. (After that printing was not checked immediately, so I'm not
sure is this related to those changes).
User NETWORK SERVICE with all permissions is added to printer users but
problem persists. Running application in development computer by pressing
F5 in visual studio with Web Developer server and calling with controller
to print to PDF Creator works OK.
How to print from controller in server ?
public ActionResult PrintTest()
{
var doc = new PrintDocument();
doc.PrinterSettings.PrinterName = "Samsung ML-331x Series";
doc.PrintPage += new PrintPageEventHandler(TestProvideContent);
doc.Print();
return new ContentResult()
{
Content = "Printed"
};
}
public void TestProvideContent(object sender, PrintPageEventArgs e)
{
e.Graphics.DrawString("Test",
new Font("Arial", 12),
Brushes.Black,
e.MarginBounds.Left,
e.MarginBounds.Top);
}
Update
Application runs at full trust Level. Application log in event viewer does
not have any entries about this.
Using Programmatically "hello world" default SERVER-side printer in
ASP.NET MVC I tried to use printer name with server name as
\\SERVER\Samsung ML-331x Series but problem persists.

Wine Fatal Error - Invalid command line parameter: -changedir
Wine Fatal Error - Invalid command line parameter: -changedir
When ever I start Plants Vs. Zombies one 'Fatal Error' window appears with
message: Invalid command line parameter: -changedir. Previously I was able
to play such games in Wine but I don't know exactly what happened.
Here is the error when I execute this game from terminal:
$ wine PlantsVsZombies.exe
fixme:ole:CoInitializeSecurity ((nil),-1,(nil),(nil),0,3,(nil),0,(nil)) -
stub!

I tried re-installing wine many times, deleted all configuration files and
other files and directories:
$ sudo find / | grep wine | sudo xargs rm -r wine
But it never worked for me. I am using latest wine1.6 downloaded from wine
repository:
$ sudo add-apt-repository ppa:ubuntu-wine/ppa
If someone knows please help me. I don't want to switch to Windows in
order to play games.

PHP remove timestamp from string
PHP remove timestamp from string
In a PHP script I need to remove the 00:00:00 from "2003-01-28 00:00:00".
No matter what numbers are in the 00:00:00 it should be stripped if
exists. Is there some sort of formula (regex maybe?) that can detect and
remove it?
Additionally, the 00:00:00 may not always be in the string. That's why I
need to detect it first.
How would I go about this? Any ideas or functions?

Correct Focus Management: JavaFX and Swing Interop
Correct Focus Management: JavaFX and Swing Interop
I've been developing Swing applications for many years, and recently tried
getting my feet wet with JavaFX. Everything's been going well for the most
part, but I'm having problems with inter-operating Swing and JavaFX
components when it comes to focus.
Basically, is there a right way to manage focus between JavaFX and Swing?
In the application I'm making, each component requests for focus in the
window when the mouse enters it's bounds. Unfortunately, this makes JavaFX
components like Popup freeze in place, instead of auto-hiding as it is
defaulted to do when it loses focus.
Thank you in advance.
Edit: To be more clear, the Popup doesn't actually freeze, buttons and
other stuff work, but TextFields become ineditable. I'm sure other
controls suffer the same problem as well.

Fibre channel long distance woes
Fibre channel long distance woes
I need a fresh pair of eyes.
We're using a 15km fibre optic line across which fibrechannel and 10GbE is
multiplexed (passive optical CWDM). For FC we have long distance lasers
suitable up to 40km (Skylane SFCxx0404F0D). The multiplexer is limited by
the SFPs which can do max. 4Gb fibrechannel. The FC switch is a Brocade
5000 series. The respective wavelengths are 1550,1570,1590 and 1610nm for
FC and 1530nm for 10GbE.
Optics
Here is the power output of one port summarized (collected using sfpshow
on different switches)
SITE-A units=uW (microwatt) SITE-B
**********************************************
FAB1
SW1 TX 1234.3 RX 49.1 SW3 1550nm (ko)
RX 95.2 TX 1175.6
FAB2
SW2 TX 1422.0 RX 104.6 SW4 1610nm (ok)
RX 54.3 TX 1468.4
What I find curious at this point is the asymmetry in the power levels.
While SW2 transmits with 1422uW which SW4 receives with 104uW, SW2 only
receives the SW4 signal with similar original power only with 54uW.
Vice versa for SW1-3.
Anyway the SFPs have RX sensitivity down to -18dBm (ca. 20uW) so in any
case it should be fine... But nothing is.
Some SFPs have been diagnosed as malfunctioning by the manufacturer (the
1550nm ones shown above with "ko"). The 1610nm ones apparently are ok,
they have been tested using a traffic generator. The leased line has also
been tested more than once. All is within tolerances. I'm awaiting the
replacements but for some reason I don't believe it will make things
better as the apparently good ones don't produce ZERO errors either.
Earlier there was active equipment involved (some kind of 4GFC retimer)
before putting the signal on the line. No idea why. That equipment was
eliminated because of the problems so we now only have:
the long distance laser in the switch,
(new) 10m LC-SC monomode cable to the mux (for each fabric),
the leased line,
the same thing but reversed on the other side of the link.
FC switches
Here is a port config from the Brocade portcfgshow (it's like that on both
sides, obviously)
Area Number: 0
Speed Level: 4G
Fill Word(On Active) 0(Idle-Idle)
Fill Word(Current) 0(Idle-Idle)

NPIV PP Limit: 126
CSCTL mode: OFF
The problem is the 4GbFC fabrics are almost never clean. Sometimes they
are for a while even with a lot of traffic on them. Then they may suddenly
start producing errors (RX CRC, RX encoding, RX disparity, ...) even with
only marginal traffic on them. I am attaching some error and traffic
graphs. Errors are currently in the order of 50-100 errors per 5 minutes
when with 1Gb/s traffic.
Forcing the links on 2GbFC produces no errors, but we bought 4GbFC and we
want 4GbFC.
I don't know where to look anymore. Any ideas what to try next or how to
proceed?
If we can't make 4GbFC work reliably I wonder what the people working with
8 or 16 do... I don't assume that "a few errors here and there" are
acceptable.
Oh and BTW we are in contact with everyone of the manufacturers (FC
switch, MUX, SFPs, ...) Except for the SFPs to be changed (some have been
changed before) nobody has a clue. Brocade SAN Health says the fabric is
ok. MUX, well, it's passive, it's only a prism, nature at it's best.
Any shots in the dark?

Ubuntu failed to upgrade
Ubuntu failed to upgrade
So i was trying to upgrade ubuntu.. and what i did was that i used the
update manager to upgrade it for me. i had the LTS version ans i was
trying to upgrade it to 12.10 so when i started the upgrade i closed all
the programs and started to upgrade and everything went well until the
installing process. it was like fail to install this package a couple of
times and then i displayed that an error occurred and that ubuntu needs to
fix and that it wil run a recovery but it didnt and when i turned off the
computer and turned it back on and tried to run ubuntu first i get the
normal purple/pink starting color with nothing going on and then the
screen flashes and goes dark then it just lights up but its black.. hope
someone can help me fix this and sorry for the weird long explanation

Call controller function from Bootstrap-UI Typeahead template
Call controller function from Bootstrap-UI Typeahead template
I am unable to call a controller-function from inside a custom-template
with ui-typeahead:
<input typeahead="val for val in autoComplete($viewValue)"
typeahead-template-url="searchAutocompleteTpl.html"
ng-model="query"/>
<script type="text/ng-template" id="searchAutocompleteTpl.html">
<span ng-repeat="eqp in match.model.equipment"/>
<a href="" ng-click="showItem(eqp.model)">
found in: {{eqp.model}}

The problem is that the controller's scope seems to be absent in the
template:
showItem(eqp.model)
is never called. I have also tried with:
$parent.showItem(eqp.model)
to no avail
How can I call a function/value on the controller's scope then?

AJAX Script - Now need to update more than one
AJAX Script - Now need to update more than one
I have a results table that allows users to delete library books from
their list of selected books at the checkout stage. I've implemented a
simple AJAX technique so that when the user clicks the Delete button next
to a book in the list it removes it from the page without having to reload
the page - this is all working well.
I now also need to update another element on the page that handles the
pagination showing how many selected books they have. At the top of the
list there is this pagination summary:
<div class="recordlist_nav">Displaying records 1 - 10 of 10 records
selected</div>
As well as removing the book from the list I also need to update this, for
example if they deleted one book it should change to:
<div class="recordlist_nav">Displaying records 1 - 9 of 9 records
selected</div>
I can generate the updated string but not sure how I get my AJAX script to
update multiple elements at the same time. Here's my script:
<script type="text/javascript">
function deleteRecord(recid,articleID) {
// Allocate an XMLHttpRequest object
if (window.XMLHttpRequest) {
// IE7+, Firefox, Chrome, Opera, Safari
var xmlhttp=new XMLHttpRequest();
} else {
// IE6, IE5
var xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
// Set up the readyState change event handler
xmlhttp.onreadystatechange = function() {
if ((this.readyState == 4) && (this.status == 200)) {
document.getElementById("selectedRecord" +
recid).innerHTML=xmlhttp.responseText;
}
}
// Open an asynchronous POST connection and send request
xmlhttp.open("POST", "delete_record.php", true);
xmlhttp.setRequestHeader("Content-type","application/x-www-form-urlencoded");
xmlhttp.send("recid="+recid+"&articleID="+articleID);
return false; // Do not follow hyperlink
}
</script>
At present the delete_record.php simply echoes out an empty string when it
deletes the selected record:
$result = '';
echo $result ;
I'm storing the updated pagination header in a $navigation variable. I now
need to pass this back to the script and have that script replace the
contents of the with the contents of the $navigation variable.
I have a results table that allows users to delete library books from
their list of selected books at the checkout stage. I've implemented a
simple AJAX technique so that when the user clicks the Delete button next
to a book in the list it removes it from the page without having to reload
the page - this is all working well.
I now also need to update another element on the page that handles the
pagination showing how many selected books they have. At the top of the
list there is this pagination summary:
<div class="recordlist_nav">Displaying records 1 - 10 of 10 records
selected</div>
As well as removing the book from the list I also need to update this, for
example if they deleted one book it should change to:
<div class="recordlist_nav">Displaying records 1 - 9 of 9 records
selected</div>
I can generate the updated string but not sure how I get my AJAX script to
update multiple elements at the same time. Here's my script:
<script type="text/javascript">
function deleteRecord(recid,articleID) {
// Allocate an XMLHttpRequest object
if (window.XMLHttpRequest) {
// IE7+, Firefox, Chrome, Opera, Safari
var xmlhttp=new XMLHttpRequest();
} else {
// IE6, IE5
var xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
// Set up the readyState change event handler
xmlhttp.onreadystatechange = function() {
if ((this.readyState == 4) && (this.status == 200)) {
document.getElementById("selectedRecord" +
recid).innerHTML=xmlhttp.responseText;
}
}
// Open an asynchronous POST connection and send request
xmlhttp.open("POST", "delete_record.php", true);
xmlhttp.setRequestHeader("Content-type","application/x-www-form-urlencoded");
xmlhttp.send("recid="+recid+"&articleID="+articleID);
return false; // Do not follow hyperlink
}
</script>
At present the delete_record.php simply echoes out an empty string when it
deletes the selected record:
$result = '';
echo $result ;
I'm storing the updated pagination header in a $navigation variable. I now
need to pass this back to the script and have that script replace the
contents of the with the contents of the $navigation variable.
[ Mathematics ] Open Question : Can fractions be multiplied on the calculator?
[ Mathematics ] Open Question : Can fractions be multiplied on the
calculator?
I am learning how to multiply fractions in the simplest form and ran
across a problem I don't know how to do. If I wanted to figure this out on
the calculator how would I go about doing it? 7/11 x 6/11= I have a
Scientific Calculator. Can I use this one, or would I need a different
type of calculator? Thank you.

Sortable images with jquery sortable in HTML
Sortable images with jquery sortable in HTML
I'm trying to make sortable images with jquery in HTML. What is wrong with
the source here? I've defined the jquery sortable function in a
functions.js file and tested it on this page with text, so I know it
works. But I can't get it to work with the divs of the images and their
respective titles. Do I have to set up the CSS for the image divs a
certain way?
Here is the source. See "sortable" for the sortable div, which surrounds
the image divs.

Adding JSON elements to two dimensional array
Adding JSON elements to two dimensional array
Good Day,
I have this JSON object that i want to push and change the two values in
to another array
var line4 = [
{"viewed":2, "sumDate":1377129600000, "redeemed" : 8},
{"viewed":12, "sumDate":1377129600000, "redeemed" : 3},
{"viewed":18, "sumDate":1377129600000, "redeemed" : 13}
];
i want the new line4 to be like this format
line4 = [["2008-06-30", 2], ["2008-7-14", 12, ["2008-7-28", 18]]
i cant seem to format it correctly to my array
$(line4).each(function (index, value) {
console.log("value: " + value);
$(value).map(function(){
d = new Date(parseInt(this.sumDate));
this.sumDate = (1 + d.getMonth()) + '/'+ d.getDate() + '/' +

console.log("sumdate : " +this.sumDate);
console.log("viewed : " +this.viewed);
line5.push([this.sumDate, this.viewed]);

If i write my comment data to logcat via System.out.println i can get data
but i couldn't wrote them to listview.
My Adapter's code:

What's wrong with my join statement? It returns BOOLEAN in PHP
What's wrong with my join statement? It returns BOOLEAN in PHP
To make my question as clear as possible (I've been moaned at previously
for being too vague), here's the structure and data of two tables I'm
working with in a project. Table 1 contains a list of football games,
table 2 contains UK football teams that will be recorded in table 1.
I'm just learning about SQL from a book I took out from the library. I've
followed the instructions on joining table data. Here, I am simply trying
to echo the data onto the page, to make sure my query is right before
styling the page around this data.
<?php
//Set DB Variables
$dbc = mysql_connect(host, username, password);
$db = mysql_select_db(database);
$results= mysql_query("SELECT 'tbl_games.game_ID',
'tbl_games.game_date', 'tbl_teams.team_name' FROM tbl_teams,
tbl_games
WHERE 'tbl_games.team1_ID' = 'tbl_teams.team_ID' AND
'tbl_games.team2_ID' = 'tbl_teams.team_ID' AND
'tbl_games.team1_score' IS NULL AND 'tbl_games.team2_score' IS
NULL");
while ($row = mysql_fetch_array($results)) {
foreach ($row as $columnName => $results) {
echo 'Column name: '.$columnName.' Column data:
'.$columnData.'<br/>';
}
}
?>
There are no errors being printed on the page when I run the code, it just
doesn't print anything. But there are (or at least should be) some results
showing up. What did I get wrong here?

I use recursive Automake since some of the thirdpaty libraries are
distributed with their own Automake files. src/Makefile.am includes the
usual libtool macros:
lib_LTLIBRARIES = libmylib.la
libmylib_la_SOURCES = scrfile1.h srcfile1.cpp ...
How do I link the main library to the third party ones? The Autotools
manual leads me to believe that the third party libraries nees to be built
as libtool conveniece libraries, so I have the following in
thirdparty/lib1/Makefile.am:
noinst_LTLIBRARIES = libthirdpaty1.la
libthirdpaty1_la_SOURCES = lib1.cpp lib1.h
And add the following in src/Makefile.am:
libmylib_la_LIBADD = $(top_buildir)/thirdparty/lib1/libthirdpaty1.la
My root Makefile.am holds the INCLUDES macro:
INCLUDES = -I$(top_builddir)/thirdparty
But building with this configuration gives me undefined symbol errors.
What is the correct way to structure this srouce code and link all the
libraries together?

Best way to manage Listview items from Indy 10 thread
Best way to manage Listview items from Indy 10 thread
I'm making a multi user remote administration tool, a sort of VNC but
which support multi remote desktop viewer a bit like Teamviewer does.
I have a Delphi Form which only contains a TListview, this listview
contains users list which are currently connected to the server.
When a connection is dropped, the listview item is deleted.
For some reason I got some random problems while deleting more than a
single item, for example if I decide to flush the whole server
connections, if I have more than 1 listview item, it start going crazy.
Sometimes no error show up, just some items remain listed, sometimes it
shows "address violations errors".
As I was before using pure Winsock API to make Client / Server
application, I maybe use badly Indy components.
A short explanation about my way of managing the Server component.
My application is Multi Server, which means user could create one or many
servers at the same time. When a new Server is created by the user it run
a new thread which will create a new indy Server component and setup
needed events (OnConnect, OnExecute, OnDisconnect) etc...
Every commands that acts with some VCL form are of course Synchronize
using the Synchronize(); delphi method.
When a new connection show up, i create from the Server Execute method a
new listview item, then i set the new listview item to the AContext.data
property.
When a connection is dropped on the OnDisconnect event, I delete the
listview item then empty the AContext data to be sure, he wont do it again
when he will be automatically destroy.
Synchronize(procedure begin
TListItem(AContext.data).Delete;
end);
AContext.data := nil;
This way of doing works very badly when I have more than a single
connection. After debugging it seems even with the Synchronize commands
are executed at the same time which could result conflicts in the VCL
form.
I'm not an expert in Indy10, any advice would be surely appreciate.
Thank you in advance and sorry for my poor english.

Does every infinite set have a denumerable subset?
Does every infinite set have a denumerable subset?
This question is answered with a mere "Yes" in the textbook (Theory of
Sets by Joseph Breuer), but I'm not sure where the confidence comes from.
For instance, if we have a non-denumerable set, then it seems to me that
no matter what pattern we choose, we'll end up with a subset with the same
cardinal number. Or won't we?
I guess what makes matters worse is that the question right after proving
the theorem that "If a denumrable set is subtracted from a non-denumrable
set, the resulting set is no-denumerable." I understood the proof, and can
even reproduce it perfectly, but I have no idea I understand what it
means. An example would make things clearer, I guess.
I'm thoroughly confused; please help!
This question is answered with a mere "Yes" in the textbook (Theory of
Sets by Joseph Breuer), but I'm not sure where the confidence comes from.
For instance, if we have a non-denumerable set, then it seems to me that
no matter what pattern we choose, we'll end up with a subset with the same
cardinal number. Or won't we?

How can I find top 5 countries with highest population per continent. I
just want to use below 1 table:
URL: http://dev.mysql.com/doc/index-other.html
Database: world database (MyISAM version, used in MySQL certifications and
training)
Below is what I came up with:
select Continent,

How to deal with unwanted characters in date with strptime in R
How to deal with unwanted characters in date with strptime in R
I have been sent many datasets with the date in the following format:
10.18.12 klo 04.00.00 ap.
10.18.12 klo 04.00.00 ip.
The dates are in Finnish. 'klo' is for time, ap. is for 'am' and ip. is
for 'pm'. I am trying to read it with strptime but I can't see how to deal
with unwanted characters like "klo", nor how I can tell strptime that what
ap and ip stand for. I thought that something like this might work
time = strptime(paste(date),format='%m.%d.%y%n%n%n%n%n%I.%M%S%n%p%n')
because I thought that I could define unwanted characters as white space
but it doesn't work. Any advice?
Thanks.

how to implement the output of decision tree built using the ctree (party
package)?
I have built a decision tree using the ctree function via party package.
it has 1700 nodes. Firstly, is there a way in ctree to give the 'maxdepth'
value.I tried control_ctree option but, it threw some error message saying
couldnt find ctree function.
Also, how can I consume the output of this tree?. How can it be
implemented for other platforms like SAS or SQL. I also have another doubt
as to what does the value "* weights = 4349 " at the end of the node
signify. How will I know, that which terminal node votes for which
predicted value.

Hibernate + MSSQL Server: using both nvarchar and char strings (jtds driver)
Hibernate + MSSQL Server: using both nvarchar and char strings (jtds driver)
Is it ever possible to use both unicode and non-unicode strings in
Hibernate (version 4) and Microsoft SQL server (2008/2012)?
What we have now - customised SQL Server dialect that generate nvarchar
for strings:
public class SQLServerUnicodeDialect extends SQLServerDialect {
public SQLServerUnicodeDialect(){
super();
// Use Unicode Characters
registerColumnType( Types.VARCHAR, "nvarchar($l)" );
...
}
At jdbc level we're using JTDS driver that convert all strings as unicode
by default (see parameter sendStringParametersAsUnicode).
So I see 2 problems in the task:
How to say hibernate separate unicode and non-unicode strings?
Which jdbc driver support both string types (looks like JTDS has 1 option
- all strings as unicode or no)?
Any thoughts are welcome.

Streaming Replication Resource Management (PGSQL) on FreeBSD 8.x
Streaming Replication Resource Management (PGSQL) on FreeBSD 8.x
I am attempting to set up PGSQL-HA streaming replication on freeBSD 8.2
(willing to upgrade to 8.4 if need be).
The set up is simple: 2 nodes, one active one standby. I have successfully
set up streaming replication between the two nodes, but I am now trying to
set up a resource agent/manager to deal with automatic failover and
STONITH.
I have attempted to use Heartbeat/Corosync/Pacemaker for this, but am
running into difficulty building them from source (Pacemaker, in
particular).
Is there an easier way than using Pacemaker for a simple 2 node set up? I
have little experience with this and especially with freeBSD.
Thanks!
*Note: FreeBSD 8.x is required, the servers are running other services
that would make it too difficult to upgrade or change the OS

But it doesn't feel right. Is there a better way to achieve what I want?

if i use "$(document).ready(function()" newly added users won't delete.
Could you please check this script for errors and tell me if it's script

How are concatenated strings allocated?
How are concatenated strings allocated?
I was wondering how strings and memory work together.
As far as I'm aware, I know that when a string is created, it puts some
array of characters + '\0' into memory. I also know that they're
immutable. So for things like concatenation, what happens in memory that
allows you to access the same string?
I don't imagine that the string or character you concatenated is put
directly after the addresses of the original strings because that might
overlap some needed memory.
In C# and other languages, you can say:
string s = "Hello" ... s = s + '!'
Would this be creating a new string? One that is pointing to a new
location that says "Hello!", leaving the original never to be referenced?
Or is there a default char buffer that strings use that allows for some
space in concatenation?

Rails - Polymorphic Self-Join Model Associations
Rails - Polymorphic Self-Join Model Associations
I'm working on building an app to keep track of product designs, and I'm
having some trouble with my associations. Basically I have a model
(Assembly) which needs to have polymorphic association, but also needs to
be able to belong to itself.
To illustrate, I have three models: Product, Assembly, and Part.
A Product can have many Assemblies.
An Assembly can have many Parts AND Assemblies.
An Assembly belongs to a Product OR an Assembly.
A Part belongs to an Assembly.
My model definitions are currently like this:
product.rb
class Product < ActiveRecord::Base
belongs_to :product_family
has_many :assemblies, as: :assemblable
end
assembly.rb
class Assembly < ActiveRecord::Base
belongs_to :assemblable, polymorphic: true
has_many :parts
has_many :subassemblies, as: :assemblable
end
part.rb
class Part < ActiveRecord::Base
belongs_to :assembly
belongs_to :product_family
end
What I would like to be able to do is, given an assembly called "top_assy":
top_assy.subassemblies.create
However, when I try this, I get the following error:
NameError: uninitialized constant Assembly::Subassembly
I'm clearly doing something wrong here - what am I missing? I have already
tried adding 'class_name: "Assembly"' as an argument to the 'has_many
:subassemblies' command.
Thanks in advance!

Why can't I compare a count of a new array?
Why can't I compare a count of a new array?
Can someone explain this to me ?
if(0 <= -1)

if([NSArray new].count <= -1)
NSLog(@"What the **** ? %i", [NSArray new].count);
if([[NSArray alloc] init].count <= -1)
NSLog(@"What the **** ? %i", [[NSArray alloc] init].count );
Output is twice What the **** ? 0 and I was expecting no output I expect
to have 0 as count.
If I put the count in a int or log it it ouputs 0 (zero), but the if
statement generates a true on this.

NSLog(@"What the **** ? %i", [[NSArray alloc] init].count );
Output is twice What the **** ? 0 and I was expecting no output I expect
to have 0 as count.
If I put the count in a int or log it it ouputs 0 (zero), but the if
statement generates a true on this.

I am building Dashboard page which contains graphs(using HighCharts for
same). my html also contains jQuery Tabs.
In one tab there are 4 different charts.charts are getting loaded properly
but it comes with vertical scroll bar. being a dashboard page i want to
hide vertical scroll bar.
Here is My HTML
<div id="container" style="width:98%;">
<ul>
<li><a href="#divP1">Dashboard</a></li>
<li><a href="#divP2">Network</a></li>
<li><a href="#divP3">> 24 Hours</a></li>
</ul>
<div id="divP1" style="margin:0 auto;">
<div id="divDailyUptimeLineChart"
style="width:650px;height:250px;float:left;"></div>
<div style="width:500px;height:250px;margin-left:750px;"
id="divUptimeGauge"></div>
<br />
<div style="clear:both;width:700px;float:left;"
id="divFaultCount"></div>
<div style="margin-left:700px;" id="divTicketTypeCount"></div>
<br />
</div>
<div id="divP2" style="margin:0 auto;">
<div id="divFaultTicketType" style="width:49%;float:left;"
></div>
<div id="divCRATicketType"
style="margin-left:49%;width:49%"></div>
</div>
<div id="divP3" style="margin:0 auto;">
