JSF 2 : Status-Description selectonemenu
I have 2 selectonemenu elements, one that contains the status of the
request, and the other contains a description of that status.
Im trying to implement it as follows :
I have a class called status that has 2 fields : status & description.
the selectonemenu would be :
<h:outputText id="requestStatusH" value="Status : " />
<h:selectOneMenu id="statusDD" value="#{exApp.status}">
<f:selectItems value="#{exApp.statusList}" />
</h:selectOneMenu>
and my bean would be :
private RequestStatus status;
private List<RequestStatus> statusList;
//Getters + Setters
when i select a status in one selectonemenu i want the corresponding
description to appear in another disabled selectonemenu.
The problem is that im not able to even get the selected value in to the
backing bean variables. after i submit the page, nothing is happening.
I tried to look into the stackoverflow selectonemenu guide, and i couldnt
find anything about converters.
any help would be highly appreciated.

How to echo multiple rows with data based on checkbox input?
How to echo multiple rows with data based on checkbox input?
Got stuck trying to echo out multiple rows with data based on checkbox
input. As of current code it processes data from only one checkbox, no
matter how many checkboxes are ticked. Please help!
while($row = mysql_fetch_assoc($r))
{
$pals .= '<input type="checkbox" name="pal_num[]"
value="'.$row['pal_num'].'">'.$row['pal_num'].'<br>';
}
if($pal == '') {
echo '';
} else {
echo '<form name="get_pal" action="post2.php" method="POST">';
echo $pals;
echo '<input type="submit" name="post" value="Go!">';
echo '</form>';
}
post2.php:
$w = $_POST['pal_num'];
$rrr = mysql_query("SELECT * FROM pl_tab WHERE pal_num".$w[0]);
while($row = mysql_fetch_array($rrr))
{
echo '<tr><td>'.' '.'</td>';
echo '<td rowspan="5">'.$row['descr'].'</td>';
echo '<td><b>'.'Total weight'.'<b></td>';
echo '<td>'.' '.'</td><td>'.' '.'</td></tr>';
echo '<td>'.' '.'</td>';
echo '<td colspan="3">'.' '.'</td>';
//this part should multiple based on how many checkboxes are ticked.

Making/Initializing Array of Struct Like Objects in Java
Making/Initializing Array of Struct Like Objects in Java
I am using Java SE on NetBeans 7.3.1.
I would like to form a Java array similar to the following in C
typedef struct sNewStruct{
int min;
int max;
} NewStruct;
NewTruct nsVar[19];
I tried the following
class IntRange{
int min, max;
}
IntRange[] rangeNodes = new IntRange[19];
My problem is that, while rangeNodes is successfully allocated, all of its
elements are nulls.

Jquery pagination - Applying class to items
Jquery pagination - Applying class to items
I am trying to design a pagination system in Jquery. The bit I am stuck on
is when I click on different page number links, I want it to move the
"active" class to the newly clicked page.
In the example page "1" has the active class. When I click "2" I want the
active class to move to "2" and be removed from "1".
http://jsfiddle.net/qKyNL/24/
$('a').click(function(event){
event.preventDefault();
var number = $(this).attr('href');
$.ajax({
url: "/ajax_json_echo/",
type: "GET",
dataType: "json",
timeout: 5000,
beforeSend: function () {
$('#content').fadeTo(500, 0.5);
},
success: function (data, textStatus) {
// TO DO: Load in new content
$('html, body').animate({
scrollTop: '0px'
}, 300);
// TO DO: Change URL
// TO DO: Set number as active class
},
error: function (x, t, m) {
if (t === "timeout") {
alert("Request timeout");
} else {
alert('Request error');
}
},
complete: function () {
$('#content').fadeTo(500, 1);
}
});
});
I'm quite new to Jqeury and could do with some help. Can anyone please
give me some guidance on how to do this?

access elements in Ruby nested hash
access elements in Ruby nested hash
I am trying to access the elements in a nested hash where keys are similar
symbols.
favs = {
:art => "painters",
:survey1 => [
{:name=>"Josh", :painter=>"Dali" },{:name=>"Mona", :painter=>"Monet"}
],
:survey2 => [
{:name => "Leon", :answer => "None"},
{:name=>"Port", :answer => "Picasso"},
]
}
Q1: Delete Leon-
I came up with this:
favs[:survey2].each { |hash|
hash.delete_if { |k,v|
v=="Leon"
}
}
but I couldn't figure out how to tie the second key value pair in (the
answer/painter) after removing just the name.
Q2 Return Josh's favorite painter - same problem, I can find :name=>Josh
but not sure how to return corresponding painter.
Thanks in advance

Would a partial index be used on a query?
Would a partial index be used on a query?
Given this partial index:
CREATE INDEX orders_id_created_at_index ON orders(id) WHERE created_at <
'2013-12-31';
Would this query use the index?
SELECT * FROM orders WHERE id = 123 AND created_at = ''2013-10-12';
As per the documentation, "a partial index can be used in a query
only if the system can recognize that the WHERE condition of the query
mathematically implies the predicate of the index". Does that mean that
the index will or will not be used?

Load images in jar file
Load images in jar file
I'm trying to load an image from an executable JAR file.
I've followed the information from here, then the information from here.
This is the function to retrieve the images:
public static ImageIcon loadImage(String fileName, Object o) {
BufferedImage buff = null;
try {
buff = ImageIO.read(o.getClass().getResource(fileName));
// Also tried getResourceAsStream
} catch (IOException e) {
e.printStackTrace();
return null;
}
if (buff == null) {
System.out.println("Image Null");
return null;
}
return new ImageIcon(buff);
}
And this is how it's being called:
logo = FileConverter.loadImage("/pictures/Logo1.png", this);
JFrame.setIconImage(logo.getImage());
With this being a simple Object. I'm also not getting a
NullPointerException unless it is being masked by the UI.
I checked the JAR file and the image is at:
/pictures/Logo1.png
This current code works both in eclipse and when it's been exported to a
JAR and run in a terminal, but doesn't work when the JAR is double
clicked, in which case the icon is the default JFrame icon.
Thanks for you're help. It's probably only me missing something obvious.

Does a TCP peer reset the connection after exhaust the send retry counter?
Does a TCP peer reset the connection after exhaust the send retry counter?
Supose a Windows TCP peer sending a TCP packet and the remote peer not
ACK'ing it neither reseting the connection (kernel crash, power/hardware
failure,etc.)
Does the windows peer reset the connection after exhaust the send retry
counter?
Does the TCP RFC say something about it?
My doubt arises after reading the following sentence (in "Re-transmission
Behavior" paragraph of this page
http://support.microsoft.com/kb/169292/en-us):
After computer "X's" retries are exhausted, you may not see a "Reset"
right away. If computer "Y" finally responds, computer "X" may then reset
the connection.
Thanks in advance and forgive me for my rudimentary english.

[Ljava.lang.String;@a0a595
Please somebody help me to solve this problem.
I am a beginner. I want to pass an array of check box values from one JSP
page to another. The page getting data is
<%
ResultSet rs=s.notapprovedqns();
%>
<%
while(rs.next())
{ %>
<tr><td><input name="qns[]" type="checkbox" value="<%
out.println(rs.getInt("question_id")); %>"
/></td><td><center><%=rs.getString("question_id")
%></center></td><td><%=rs.getString("question") %></td></td></tr>
<%
}
%>
How can i receive check box values in JSP another page. I have tried the
following code but its not working properly
String[] h=null;
h=request.getParameterValues("qns[]");
But its passing the value
[Ljava.lang.String;@a0a595
Please somebody help me to solve this problem.
Troubles using jquery on a form
Troubles using jquery on a form
I'm trying to use Jquery in order to validate a form's input. On top of
that, I want to auto-fill some fields if they are left blank. Here is how
I proceed :
$(form).submit(function () {
var result = true;
var timeRegex = /^([0-9]|0[0-9]|1[0-9]|2[0-3]):([0-5][0-9])$/;
if ($("#newStartTime").val().length == 0)
$("#newStartTime").val("00:00");
if (!timeRegex.test($("#newStartTime").val())) {
$("#newStartTime").wrap("<div class='error' />");
result = false;
}
return result;
});
What's happening here is that the input is set to 00:00, but the submit is
rejected (and the field wrapped as an error). If I re-click on submit, it
works fine.
The way I see things, Jquery doesn't treat the modifications made after
the 'submit' was called. If that's the case, is there a way to achieve
what I want without using ".submit()" twice ? If I'm mistaken, what's
wrong ?

How can I use a macro for collecting variable names?
How can I use a macro for collecting variable names?
I would like to simplify the following
class A {
int a;
int b;
int c;
std::vector<int*> addrs;
public:
A() : addrs{ &a, &b, &c } {}
};
so that I don't have the write the list of fields in two places, i.e. the
declarations and the initializer for addrs. Is there some way to use a
macro to collect the declarations and use them later. E.g.,
class A {
VAR_DECL(a);
VAR_DECL(b);
VAR_DECL(c);
std::vector<int*> addrs;
public:
A() : addrs{ VAR_ADDRESSES } {}
};
For context this is intended for implementing some kind of property
introspection system.

blueimp/jQuery-File-Upload & jquery tree traversal methods on input element
blueimp/jQuery-File-Upload & jquery tree traversal methods on input element
I'm trying to implement file uploading with the help of
https://github.com/blueimp/jQuery-File-Upload and have come across some
weird behavior that I hope somebody can explain to me, or it might
actually be a bug, I don't know.
I followed the minimal setup guide
(https://github.com/blueimp/jQuery-File-Upload/wiki/Basic-plugin) and
setup a new project where I change this (only the script):
<body>
<input id="fileupload" type="file" name="files[]" multiple>
</body>
-
<script>
$(function () {
$('#fileupload').fileupload({
dataType: 'json',
done: function (e, data) {
$.each(data.result.files, function (index, file) {
$('<p/>').text(file.name).appendTo(document.body);
});
}
});
});
</script>
to this (to illustrate the issue I have). I introduce a variable and
assign $('#fileupload') to it and work with the variable from there on:
<script>
$(function () {
var $elem = $('#fileupload');
$('#fileupload').fileupload({
dataType: 'json',
done: function (e, data) {
$.each(data.result.files, function (index, file) {
$('<p/>').text(file.name).appendTo(document.body);
});
}
});
$elem.on('change', function(e) {
console.log($elem.parent());
console.log($elem.next());
console.log($elem.prev());
console.log($elem.siblings());
});
</script>
Int the second example for some reason jQuery's tree traversal methods
like parent(), next(), prev() or sibling() won't work with
$elem
any more after clicking the input button and loading some random image. Is
this a bug or am I simply missing something here?
thx for the help

What does the standard say about how calling clear on a vector changes the capacity?
What does the standard say about how calling clear on a vector changes the
capacity?
This website implies that clearing a vector MAY change the capacity:
http://en.cppreference.com/w/cpp/container/vector/clear
"Many implementations will not release allocated memory after a call to
clear(), effectively leaving the capacity() of the vector unchanged."
But according to @JamesKanze this is wrong and the standard mandates that
clear will not change capacity.

No module named zlib in python 2.6?
I tried to install Python2.6(built from source) in my Debian 7 system, but

I have installed both zlib1g and zlib1g-dev, and built it again but still
failed. Also, I have tried ./configure --with-zlib and ./configure

I really got zlib.h in /usr/include/zlib.h which version is 1.2.7.
And I found this in setup.py under Python 2.6 source code:
I tried to debug to figure out why.When I jump to line 1131, it was False
and jump to line 1140. So, I was told I didn't have zlib! (Why?)

Setting Sql Query Output to a list in ASP.NET
Setting Sql Query Output to a list in ASP.NET
I'm working on a project for work, and this issue has been holding me up
all day. My database consists of 9 Columns that are used to identify a
specific row based on user inputs and 7 columns that contain the relevant
data for that user given their inputs match the first 9 columns of the row
match. This may not be the most efficient way of structure the database,
but it's an artifact of the prototype and I'd really rather not change it.
I have a SQL Query that selects the correct row based on the user's
inputs, and now I want to assign a variable to each of the remaining 7
columns (called OA5,OA10,OA15,OA20,OA25,OA30,and OALife), so that I can
graph them for the user. I haven't been able to figure out how to do this
given the way I have my sql query structured below.

How to stream screen from Android device to another Android
How to stream screen from Android device to another Android
I have a game implemented with OpenGl 1.x. I'd like to create multiplayer
mode that requires streaming from one's screen to another device's screen
(and vice versa). Can anyone direct me to find the best solution for
getting the whole screen, stream it to the other device and show the
stream on a part of the other device?
I was thinking about using Java Sockets for this, but I don't know how to
screen the stream that I currently being shown on the GLSurfaceView. And
I'm not even sure the Sockets are the most efficient solution for this (Is
there any other?)

Extraction Of Face From a Bitmap
Extraction Of Face From a Bitmap
After being given suggestions to use circular crop i implemented it in my
application to use to extract face from the bitmap but its too inefficient
i mean its of no use and similar to cropping from the rectangular face.
Now here is what i have done up til now:
Launched Camera
Taken Picture
Detected The face in the Picture
Painting a rectangular window in the area face has been detected
Now the serious issue am facing is getting face from that bitmap. I just
want to get the face. Ignore all the other details that were in the face
detection window. If it was matlab it could have been too simpler with the
help of edge detection techniques and segmentation algorithms and
function. I want to know how can i do the same process in android
application? plz do share the code snippets if u know of any. This is
taking too much of my time and i just want to get over with this face

Spring transactional dont rollback when exception is mapped by ExceptionMapper
Spring transactional dont rollback when exception is mapped by
ExceptionMapper
I have a RestFull service (implemented by jersey) . The service is marked
with @Transactional.
I declared an ExceptionMapper like this:
@Provider public class ThrowableMapper implements ExceptionMapper {
private static final Logger log = Logger.getLogger(ThrowableMapper.class);
public Response toResponse(Throwable ex) {
log.error("throwable", ex);
return Response.status(500).entity("Internal
Error").type("text/plain").build();
}
}
when exceptionmapper is not declared than transaction is rollback.
However, when i have an ExceptionMapper transaction is commit without
rollback.
I assume that since exception is caught by ExceptionMapper than spring
transaction proxy dosnt detect that exception was thrown ,so transaction
is not rollback.
Is there a way to overcome this?

GD resize image and crop edges
GD resize image and crop edges
Basically if I have a 3400x3400 image and my target size is 340x200 then I
would like to grab the respective 3400x2000 from the middle of the
original image and then scale it down to 340x200, I have a rough idea of
how it will look, here is what I have so far:
$RealWidth=164;
$RealHeight=126;
$org_img = imagecreatefromjpeg($newname);
list($width, $height) = getimagesize($newname);
$ratio2 = $height/$width;
$ratio = $RealHeight/$RealWidth;
$img = imagecreatetruecolor($RealWidth,$RealHeight);
$ims = getimagesize($newname);
imagecopyresized($img,$org_img, 0, 0, 0, 0, $RealWidth, $RealHeight,
$height*$ratio2, $height);
imagejpeg($img,$newname,90);
imagedestroy($img);
I am a bit confused with the math, I also want it to be able to crop a
region from the top/bottom if needed as well.

C++ or Cython memory leakage?
C++ or Cython memory leakage?
I am working on a python extension module written in cython, that wraps a
C++ class I have written.
The crash
I have a simple python code that imports this python module and process
some data with it. Now, about 1 time out of 4, the program segfaults just
before termination, after the calls to the module. This meaning as well
that all the data is correctly processed. It segfaults like this:
/Users/axe/anaconda/bin/python.app: line 2: 73168 Segmentation fault: 11
debugging with gdb, running gdb python and then run code.py, I get
Program received signal EXC_BAD_ACCESS, Could not access memory.
Reason: 13 at address: 0x0000000000000000
0x00000001000894ae in PyObject_ClearWeakRefs ()
the output of backtrace is
#0 0x00000001000894ae in PyObject_ClearWeakRefs ()
#1 0x00000001010edae4 in array_dealloc ()
#2 0x000000010007503e in tupledealloc ()
#3 0x00000001000559b7 in insertdict_by_entry ()

#8 0x0000000100107e1b in Py_Main ()
#9 0x0000000100000f54 in start ()
So the segfault happens outside of my python code. I mention that the
problem persists if I run the code from within ipython, or change
interpreter/ipython to the one from the Enthought distribution, or if I
downgrade Cython from 1.9.1 to 1.6.
Memory leakage in C++ (?)
Since this could look like a memory leak (please let me know if there are
other possible explanations) in the C++ code, I ran Valgrind on some C++
test code of the C++ class, but it didn't find any problems. (I am not
100% sure it is free of problems, because I am on OSX Mountain Lion, and
despite having used the latest trunk version of Valgrind, it is known to
have problems. I am using a OSX10.8 suppression file, with the one
suggested here as a start). Anyway, the C++ class doesn't use
new/delete/malloc/free, so it SHOULD be fine.
Memory leakage in Cython (?)
I tried running valgrind on the python code that crashes. I have added a
python suppression file in addition to the OSX suppression file mentioned
above. Valgrind generates a lot of output and then crashes. In the output
there isn't any reference to my source codes. This is the incriminated
cython code:
def split_props(np.ndarray[fptype, ndim=1, mode="c"] x,
np.ndarray[fptype, ndim=1, mode="c"] y,
np.ndarray[fptype, ndim=1, mode="c"] ylines):
cdef np.ndarray[fptype, ndim = 1, mode = "c"] areas =
np.zeros((ylines.shape[0] + 1), dtype=np.float64, order="c")
cdef np.ndarray[fptype, ndim = 1, mode = "c"] static_moments_x =
np.zeros((ylines.shape[0] + 1), dtype=np.float64, order="c")
cdef np.ndarray[fptype, ndim = 1, mode = "c"] inertia_moments_xx =
np.zeros((ylines.shape[0] + 1), dtype=np.float64, order="c")
cdef SplitPolygon * SPINSTANCE = new SplitPolygon(100, 100)
SPINSTANCE.split_props(& x[0], # = <fptype *> x.data
& y[0],
x.shape[0],
& ylines[0],
ylines.shape[0],
& areas[0],
& static_moments_x[0],
& inertia_moments_xx[0]
)
del SPINSTANCE
return areas, static_moments_x, inertia_moments_xx
Above, the C++ class is SplitPolygon. In the python code, I import from
the cython module only the function split_props above, so the memory leak
must be in this part of the code or in the C++ code. Moreover, the
functionality of the python code is the same of the C++ test code.
I report below also another part of the module, that is very similar, but
does NOT cause any memory leakage
def SplitCirc(np.ndarray[fptype, ndim=1, mode="c"] ycenters,
np.ndarray[fptype, ndim=1, mode="c"] radii,
np.ndarray[fptype, ndim=1, mode="c"] ylines):
cdef np.ndarray[fptype, ndim = 1, mode = "c"] areas =
np.zeros((len(ylines) + 1), dtype=np.float64, order="c")
cdef np.ndarray[fptype, ndim = 1, mode = "c"] static_moments_x =
np.zeros((len(ylines) + 1), dtype=np.float64, order="c")
cdef np.ndarray[fptype, ndim = 1, mode = "c"] inertia_moments_xx =
np.zeros((len(ylines) + 1), dtype=np.float64, order="c")
split_circles(& ycenters[0], & radii[0], len(ycenters),
& ylines[0], len(ylines),
& areas[0], & static_moments_x[0], & inertia_moments_xx[0])
return areas, static_moments_x, inertia_moments_xx
Now, I am really stuck at this point. Does the cython code look good to
you? Is there any test case I can code to check that the C++ class
SplitPolygon is really leak-free? Can the crash happen for some other
reasons?

Why does my Android OS state that there's, "Not enough free space to install the program", when there's plenty of free space?
Why does my Android OS state that there's, "Not enough free space to
install the program", when there's plenty of free space?
My hard drive on my smartphone has 100 MB free, and the app I'm trying to
install is 2 MB.
I just recently deleted apps totalling to about 88.3 MB, and the computed
size has already been adjusted, and is displayed on the screen.
However, I have to wait 10 or 15 minutes to install it.
It's as if the updated, computed space is not registered in some way to
the operating system immediately.
It's Android 2.3.4 Gingerbread, no root, no unlocked; factory pre-set all
the way(not for long though).
So, basically, is that the problem? Why do I have to wait a while after
uninstalling apps, and re-computing space availability to above par to
install a new, extremely small app, to actually work?
Is this all the OS's fault, or is something else at play here(e.g., hard
drive or circuit-level operations reigning outside the control of just the
OS software)?
Because if the re-computed size is what it's going to be, at least let the
end-user know that rather than give the impression that you have the
available space, but it won't install anything.

Packed structure reading from EFS giving strange result
Packed structure reading from EFS giving strange result
I have created one EFS item, that has the following structure struct {
uint8 version; // uint8 - 1 byte data type, uint16 - 2 byte uint16 y1;
uint16 y2; uint16 y3; uint8 reserved[9]; } Now the EFS file size comes out
to be 16 byte, so I think it is packed.
Now I have same structure, on which on power up I read the values from
EFS, But the Size of the structure returned by my compiler comes out to be
18 byte( Compiler doesn't support Packing, so EFS reading was failing).
I read only 16 byte and It passed.
Questions: 1. If I read only 16 byte, isn't there a risk of data loss, as
After the first member there will be one byte padded space in my
structure( as my compiler doesn't support Packed structure and I cannot
use it) I wrote the following values to the EFS, version -0 y1 -6 y2 -10
y3 -60
I read only 16 byte, and every member of my structure was assigned correct
values. is there any scenario where my structure will have wrong values.
Due to confusion at step one, i created one temporary struture like below
struct { uint8 version; uint8 y1_a; uint8 y1_b; uint8 y2_a; uint8 y2_b;
uint8 y3_a; uint8 y3_b; uint8 reserved[9]; }
Now both the EFS and structure size is 16 byte, Now when I give the input
to EFS as version =0, y1=6, y2=10, y3=60,
The members are assigned values like this :version=0,y1_a = 6, y1_b =0,
y2_a = 10, y2_b =0, y3_a =60, y3_b =0;
can someone help in understanding this? My idea is to read in temp
structure( so that both the size of EFs and my structre comes out to be
same) and then assign values to my original struture from temp struture
I have created one EFS item, that has the following structure struct {
uint8 version; // uint8 - 1 byte data type, uint16 - 2 byte uint16 y1;
uint16 y2; uint16 y3; uint8 reserved[9]; } Now the EFS file size comes out
to be 16 byte, so I think it is packed.
Now I have same structure, on which on power up I read the values from
EFS, But the Size of the structure returned by my compiler comes out to be
18 byte( Compiler doesn't support Packing, so EFS reading was failing).
I read only 16 byte and It passed.
Questions: 1. If I read only 16 byte, isn't there a risk of data loss, as
After the first member there will be one byte padded space in my
structure( as my compiler doesn't support Packed structure and I cannot
use it) I wrote the following values to the EFS, version -0 y1 -6 y2 -10
y3 -60
I read only 16 byte, and every member of my structure was assigned correct
values. is there any scenario where my structure will have wrong values.
Due to confusion at step one, i created one temporary struture like below
struct { uint8 version; uint8 y1_a; uint8 y1_b; uint8 y2_a; uint8 y2_b;
uint8 y3_a; uint8 y3_b; uint8 reserved[9]; }
Now both the EFS and structure size is 16 byte, Now when I give the input
to EFS as version =0, y1=6, y2=10, y3=60,
The members are assigned values like this :version=0,y1_a = 6, y1_b =0,
y2_a = 10, y2_b =0, y3_a =60, y3_b =0;
can someone help in understanding this? My idea is to read in temp

Rename terms in fitted model object
Rename terms in fitted model object
I have a list of regression models which all the same number of terms
(that is, the same number of predictive variables). Substantively, that
they all have different model terms is right. But when it comes to putting
them in a regression table, I want them all the models to share a single
formula, simply for the sake of presentation.
Some indicative data
library(plyr)
d1 <- data.frame(y = rnorm(100),
x1 = runif(100),
x2 = runif(100),
x3 = runif(100),
x4 = runif(100))
Fit the models
mods.form <- paste("y ~ x", 1:4, sep = "")
mod.list <- llply(mods.form, function(i) lm(i, d1))
Here are the terms I want to modify
llply(mod.list, function(i) attr(terms(i), "variables"))
[[1]]
list(y, x1)
[[2]]
list(y, x2)
[[3]]
list(y, x3)
[[4]]
list(y, x4)
I want every model in the list to have the same variable names as the
first model, so I tried:
mod.list2 <- llply(mod.list, function(i) attr(terms(i), "variables") =
list("y", "x1"))
which provides this error
Error in attr(terms(i), "variables") = list("y", "x1") :
could not find function "terms<-"
Is there a simple solution here?

Best network file system for live development
Best network file system for live development
I used to have a local development server (nginx+php-fpm+mysql) on my
workstation.
But then I got problems and had to reformat and found out that
reconfiguring everything right on OS X can be a pain in the butt
sometimes. So now I'm configuring my local server as my new development
server.
Now I need to know what network file system would be the most appropriate
for live development? I'm developing on OS X so that needs to be fast
using OS X. For example using NFS is a bad idea when using OS X since it's
slow.
I thought of maybe using AFP which is Apple's own network file system but
I wanted to have advice before doing so as in my memory configuring AFP is
kinda complex.
Any suggestion is welcome!
Thanks and have a nice day

C# Can I make a namespace accessible everywhere in my dot net web site for code-behind and classes
C# Can I make a namespace accessible everywhere in my dot net web site for
code-behind and classes
I have an extension method for String that I want to be available on every
code behind and class in my solution. The method is sitting in a
particular namespace. I'd like everywhere to have access to that namespace
without me having to include it in every class.
I've used the "namespaces" tag in the web config to successfully include
it on every aspx page, but this does not make it accessible on code behind
or elsewhere.
So, is there a similar way to include a namespace everywhere?

How to find out which backported packages are available, and avoid losing packages when manually upgrading?
How to find out which backported packages are available, and avoid losing
packages when manually upgrading?
I was surprised to see that since Natty 11.04, even when we have enabled a
backports repository, updated packages aren't automatically installed from
that repository. We have to install individual updates manually, e.g. via
apt-get install ipython/precise-backports
as explained at UbuntuBackports - Community Ubuntu Documentation. I guess
I just didn't get the memo....
First question: how do we find out what our options are for upgrades via
backports? I'm surprised that even if I ask for status, e.g. via
wajig status ipython
it doesn't tell me there is a new version available. I'd like a list of
all upgrades for packages which I've already installed.
Next, how do I avoid losing existing packages just because I upgrade via a
backport?
E.g. the above ipython install tells me:
The following packages will be REMOVED:
ipython-notebook ipython-qtconsole
How do I say I want the latest backported ipython, as well as any other
packages for which updates are available that depend on it, without
manually figuring them all out and installing them also?
I know I can change the pinning so that I get all updates, but I'm
hesitant to go against the general advice not to. But if a user asks for
one package to be updated, wouldn't it be natural to update all the
dependencies, like you'd get from a ppa?

Overlay 2 PDF documents within a C/C++ application
Overlay 2 PDF documents within a C/C++ application
Been trying to figure this problem out for quite a while and haven't had
much luck. So I have this program that outputs a PDF file (1.3 version).
The Outputted PDF is basically a plain text PDF so the idea is to have the
user open another PDF which has graphics and have the text PDF overlay the
other.
However I haven't been able to find any way to do this for C/C++. Is there
a API that I could use? Would need to work for both Mac/Windows OS.
Any assistance would be greatly appreciated. Thank you.

Slow file transfer with VM EXSi 4.0: I tried everything but it's still slow
Slow file transfer with VM EXSi 4.0: I tried everything but it's still slow
I was asked to setup an older HP server with VMware and some Virtual
machine window servers.
File transfer from another machine on the network to the Win 2008 server
VM is ultra slow(under 70kbs usually). What's really strange is that it
occasionally is much fast(7MB+) but usually reverts back later.
Hardware:
Corsair SSD
Nvidia 10/100 mbs onboard NIC(set for auto negotiation)
Netgear Gigabyte switch(the higher end models for server rooms)
HP Proliant DL385 running Vmware 4.0.0 ESXi(NIC also set for auto
negotiation)
Other info:
The VM has it's own separate AD and Domain since it's intended to be
installed in a new office but the DNS/DCHP server isn't configured yet.
So far I've tried:
Disabling all TCP offloading options on both NIC cards: in the card menu
and via the registry
Tried the E1000 and VMXnet3 NIC on the VM...no difference
Removed a dying hard drive from the RAID array
Various network configurations
Disabling firewalls on both
Installed VMtools
Monitored the server stats; memory, cpu, etc. aren't being stressed
greatly at all by the VM.
Moving files on the same disk to another location via another
computer(accessed as a shared network folder) moves just as slowly. If I
connect and do the same thing via RDP the speed is 7-10mb moving them on
the same disk.
I'm completely befuddled....any ideas? Could it be some security
rule/configuration that I need to remove? Upgrade to the lastest VM?

Bind slave records are unreadable
Bind slave records are unreadable
I noticed that a month or two ago that my bind records for the slave
server became unreadable. The consequence of having an unreadable record
is that it appears as though Webmin cannot read the record. I used to be
able to go into Webmin on the slave machine to validate that the record
was updated there, I can no longer do that.
It appears to still be a valid record because I can query the server
itself and it returns the same data (NSLOOKUP, etc). So it appears as
though Bind can read the file fine.
I would like this resolved, but I'm not sure where to look. Any thoughts?

JQuery get id from $(this) not working, but getting another attribute does
JQuery get id from $(this) not working, but getting another attribute does
I've searched the web and tried every proposed method I can find, but
nothing seems right for my case.
The problem is this: I need to get the id of the checked element so I know
which element to change/manipulate later.
My problem is most curious because I do a $(this).attr("tag"); and get the
right value returned for later use.
But then I try $(this).attr("id") and when I alert it, it's just an empty
alert. I have also tried alternate methods.
I've done this.id and var $this = $(this); $this.id/$this.attr("id");
I cannot for the life of me figure out why it works on one attribute, but
not another when they're both within the same method, right after one
another.
$('.jq-toggleExternal').click(function () {
var refNo = $(this).attr("tag");
var checked = $(this).find(':checkbox').is(':checked');
var controls = getReferenceContolsByRefNo(refNo);
var id = $(this).attr('id');
alert(id);
<asp:CheckBox ID="r_chkRef1External" runat="server"
CssClass="jq-toggleExternal"
tag="1" Text="Ekstern" onClick="changed(this)" />
I've also tried changing the ID to id, but same result and if I change the
attr search to attr("ID") it says undefined.
Any possible solutions/alternative ways to get the id is highly appreciated.

How to deploy a simple Drools application?
Please note that this is not a web-application. It's just a simple rules
engine application that evaluates a set of facts pertaining to a set of
POJO variables.
I couldn't find any specific information on the official Drools website or
in Google search results/stack overflow.
I'm working my way through the Drools examples
(http://docs.jboss.org/drools/release/5.5.0.Final/drools-expert-docs/html_single/#d0e8772)
on Eclipse and would like to deploy a simple example on a Linux machine -
as a stepping stone to deploying a more complex application.
Shouldn't this be straightforward as in exporting a runnable JAR from
Eclipse, copying out this JAR to a Linux machine and then invoking this
JAR by way of # java -jar .jar ?
Help appreciated. Thanks.

Use "appId|appSecret" as access_token
Use "appId|appSecret" as access_token
I've found in documentation that it is possible to use appId and appSecret
pair as access_token in the format "appId|appSecret".
The problem, when I'm using this technique with graph API, I don't receive
the full information, only some of the fields (permissions are set in the
app settings). When I'm trying to use it with FQL I get "A user access
token is required to request this resource." exception.
Could somebody route me on the right track how to perform API requests?
My application is running on the server-side, that's why I've chosen these
method.

Can you write a c# decorator function that can take any number of arguments?
Can you write a c# decorator function that can take any number of arguments?
I currently have code which acts much like a python decorator, it takes a
function as argument and returns the same function wrapped by another (in
this case opening and closing a perforce connection).
public Func<TArg, TReturn> EnableP4<TReturn, TArgs>(Func<TArg,
TReturn> function)
{
Func<TArg, TReturn> p4Wrapper = (TArg funcArg) =>
{
try
{
if (con.Status.Equals(ConnectionStatus.Disconnected)) {
con.Connect(options); }
return function(funcArg);
}
finally { con.Disconnect(); }
};
return p4Wrapper;
}
At the moment this only works for functions with one argument and I was
wondering if it could be made more general (maybe if there is a way of
unpacking an array into a method?).
(Something along the lines of this?)
public Func<TArgs, TReturn> EnableP4<TReturn, TArgs>(Func<TArgs,
TReturn> function)

if (con.Status.Equals(ConnectionStatus.Disconnected)) {
con.Connect(options); }
return function(*args);
}
finally { con.Disconnect(); }

Javascript - Get LONG* from COM/ActiveX
Javascript - Get LONG* from COM/ActiveX
I'm using an embedded ActiveX media player which I'm calling from
JS/JQuery. I can call functions and set properties in the player without
issue. However, one of the properties I need from the ActiveX control is a
LONG* pointer, which has the signature....
get_CurrentPlaybackTime_Sec(LONG* pVal)
..and I'm not really sure where to start. I've done some Googling and
found some loose references to BSTR in Javascript, but I'm unsure how to
implement it. I need an equivilent of an 'out' that I use in C# I suppose.
Here is where I am so far...
$("#fooBtn").click(function(){
var currTime;
o.get_CurrentPlaybackTime_Sec(currTime);
$("#fooDiv").text(currTime);
});
Can someone point me in the right direction please? Any help much
appreciated.

Custom UITableViewCell Indentation Issue
Custom UITableViewCell Indentation Issue
I've got an interesting problem (please forgive me if this was asked... I
searched Google, actually Bing since I don't use Google, and stack with no
results).
I am creating a custom UITableViewCell with UIIMageView (310 x 310) inside
of the content view of the cell. When everything is said and done and I
actually set the image of the imageView in my controller using cellForRow:
[feedCell.imageView setImage:[UIImage imageNamed:@"image-placeholder"]];
I get this result:
^ Not what I want.
When I get the image view from the tableView using viewWithTag method and
then set the image of the imageView directly, I get the desired result:
UIImageView *imageView = (UIImageView *)[tableView viewWithTag:1];
[imageView setImage:[UIImage imageNamed:@"image-placeholder"]];
So the question is, what is it that I am missing? Why would setting the
imageView via custom cell class be so off while it works otherwise? I
would love to use custom subclass.
P.S. Don't mind Batman stuff. Although I am kind of a fan... liked the 2nd
one the best.

Finding path, the sum of whose numbered edges is 48
Finding path, the sum of whose numbered edges is 48
Let $G$ be a graph with vertices $\{1,...,10\}$. Two vertices $a,b$ have
an edge if $a|b$ or $b|a$. Find a path in $G$ so that the sum of the
corners in the path equals 48.
I solved this using "brute force", $9-3-6-2-8-4-1-10-5$, but is there a
more efficient way? In particular one that doesn't rely on drawing the
graph in a clever way.

Data structure with fast contiguous ranges retrieval
Data structure with fast contiguous ranges retrieval
Imagine data structure, that manipulates some contiguous container, and
allows quick retrieval of contiguous ranges of indices, within this array,
that contains data (and probably free ranges too). Let's call this ranges
"blocks". Each block knows its head and tail index:
struct Block
{
size_t begin;
size_t end;
}
When we manipulating array, our data structure updates blocks:
array view blocks [begin, end]
--------------------------------------------------------------
0 1 2 3 4 5 6 7 8 9 [0, 9]
pop 2 block 1 splitted
0 1 _ 3 4 5 6 7 8 9 [0, 1] [3, 9]
pop 7, 8 block 2 splitted
0 1 _ 3 4 5 6 _ _ 9 [0, 1] [3, 6] [9, 9]
push 7 changed end of block 3
0 1 _ 3 4 5 6 7 _ 9 [0, 1] [3, 7] [9, 9]
push 5 error: already in
0 1 _ 3 4 5 6 7 _ 9 [0, 1] [3, 7] [9, 9]
push 2 blocks 1, 2 merged
0 1 2 3 4 5 6 7 _ 9 [0, 7] [9, 9]
Even before profiling, we know that blocks retrieval speed will be
cornerstone of application performance. Basically usage is: - very often
retrieval of contiguous blocks - quite often write - quite rare
insertions/deletions
What we have already tried:
std::vector<bool> + std::list<Block*>. On every change: write true/false
to vector, then traverse it in for loop and re-generate list. On every
query of blocks return list. Slower than we wanted.
std::list<Block*> update list directly, so no traversing. Return list.
Much code to debug/test.
Questions:
Is that data structure has some generic name?
Is there already such data structures implemented (debugged and tested)?
If no, what can you advice on fast and robust implementation of such data
structure?
Sorry if my explanation is not quite clear.

Passing a cursor to an Oracle stored procedure via MyBatis
Passing a cursor to an Oracle stored procedure via MyBatis
I have a stored procedure which takes a list of records as a cursor. I
would like to call it from a MyBatis mapper. I assumed that this would be
similar to reading a cursor as an output parameter, but this does not
appear to be the case. Below is the mapper entry:
@Select({CALL pkg_transaction_info.pr_transaction_add("
+ "#{pcur_trx_info, mode=IN, jdbcType=CURSOR,
javaType=java.sql.ResultSet, resultMap=txnInfoRM})
@ResultMap("txnInfoRM")
@Options(statementType = StatementType.CALLABLE)
public void addTransactionInfo(Map<String, Object> params);
... where txnInfoRM describes the mapping between my Java objects and the
columns that the stored procedure expects. In the parameter map I've tried
passing in a list of objects, hoping that the translation to a ResultSet
would happen implicitly, as it does when receiving a cursor as an output
parameter, but to no avail. Is it even possible to pass in a Cursor in
this manner? Do I need to write a custom typehandler to open it for me
using the Oracle api?

I set it to 1, I get 300 as answer.
int f;
f = (((mv*ptv*txtv)/10^3)*100);

Formatting Decimal Number
Formatting Decimal Number
I am formatting decimal number and I have the following criteria to format
it:
Number should be atmost two decimal places (10.1234=>10.12)
If there is only one digit after decimal then it will ends up with 0
(10.5=>10.50)
Thousand separator will be comma (12345.2345 => 12,345.23)
I have written following logic:
double x = Double.parseDouble(value.toString());
String dec = x % 1 == 0 ? new
java.text.DecimalFormat("###,###.##").format(x) : new
java.text.DecimalFormat("###,###.00").format(x);
Now it is printing:
11111111111110.567=>11,111,111,111,110.57
111111111111110.567=>111,111,111,111,110.56
1111111111111110.567=>1,111,111,111,111,110.60
11111111111111110.567=>11,111,111,111,111,110
111111111111111110.567=>111,111,111,111,111,104
1111111111111111110.567=>1,111,111,111,111,111,170
I don't understand why the behavior changes. If I what to print
1111111111111111110.567 as 1,111,111,111,111,111,110.57 what should I do?

Terminal Command Fails because of Space in Path
Terminal Command Fails because of Space in Path
I tried setting up a Ruby on Rails project on my nice safe volume "Data
RAID". The set up with some strange that I eventually tracked down to the
space in the path name. It works if I execute it on another volume. I
tried setting up a symlink to the directory, which works fine with the CD
command, but doesn't help with the set up. Is it possible to get an
application to use a symlink or other method that avoids the pathname with
a space?
The command I'm running that error out is
Rails new projectnamae
One other twist is something I set up to specify the location of the gems:
mkdir ~/.bundle
touch ~/.bundle/config
echo 'BUNDLE_PATH: vendor/bundle' >> ~/.bundle/config
It is with the gems that I'm getting the error.

java.lang.OutOfMemoryError: GC overhead limit
java.lang.OutOfMemoryError: GC overhead limit
I have a program that reads a large list of sequences from a file and does
a calculation among all of the pairs in that list. It then stores all of
these calculations into a hashset. When running this program about halfway
through, I get a GC overhead limit error.
I realize this is because the garbage collector is using up 98% of the
computation time and is unable to recover even 2% of the heap. Here is the
code I have:
ArrayList<String> c = loadSequences("file.txt"); // Loads 60 char DNA
sequences
HashSet<DNAPair,Double> LSA = new HashSet<DNAPair,Double>();
for(int i = 0; i < c.size(); i++) {
for(int j = i+1; j < c.size(); j++) {
LSA.put(new
DNAPair(c.get(i),c.get(j)),localSeqAlignmentSimilarity(c.get(i),c.get(j)));
}
}
And here's the code for the actual method:
public static double localSeqAlignmentSimilarity(String s1, String s2) {
s1 = " " + s1;
s2 = " " + s2;
int max = 0,h = 0,maxI = 0,maxJ = 0;
int[][] score = new int[61][61];
int[][] pointers = new int[61][61];
for(int i = 1; i < s1.length(); i++) {
pointers[i][0] = 2;
}
for(int i = 1; i < s2.length(); i++) {
pointers[0][i] = 1;
}
boolean inGap = false;
for(int i = 1; i < s1.length(); i++) {

I thought that this was because of all the variables I declare inside the
method (the two int arrays and the stringbuilders etc.) creating more and
more objects every time the method is run so I changed them all to static
fields and cleared them everytime (ex. Arrays.fill(score,0);) instead of
creating a new object.
However this didn't help at all and I still got the same error.
Could it be that the hashset that stores all of the calculations is
getting too big and is unable to be stored by java? I'm not getting an out
of heap space error so it seems kind of strange.
I also changed the command line argument to give more space to the JVM but
that didn't seem to help.
Any insight on this problem would be helpful. Thanks!
I have a program that reads a large list of sequences from a file and does
a calculation among all of the pairs in that list. It then stores all of
these calculations into a hashset. When running this program about halfway
through, I get a GC overhead limit error.
I realize this is because the garbage collector is using up 98% of the
computation time and is unable to recover even 2% of the heap. Here is the
code I have:
ArrayList<String> c = loadSequences("file.txt"); // Loads 60 char DNA
sequences
HashSet<DNAPair,Double> LSA = new HashSet<DNAPair,Double>();
for(int i = 0; i < c.size(); i++) {
for(int j = i+1; j < c.size(); j++) {
LSA.put(new
DNAPair(c.get(i),c.get(j)),localSeqAlignmentSimilarity(c.get(i),c.get(j)));
}
}
And here's the code for the actual method:
public static double localSeqAlignmentSimilarity(String s1, String s2) {
s1 = " " + s1;
s2 = " " + s2;
int max = 0,h = 0,maxI = 0,maxJ = 0;

I need to submit the form with the enter key, but it is not like the other
questions in this website in my case. I do not have a

MySQL sort varchar as number issue
MySQL sort varchar as number issue
I have seen lots of question like this on SO and I tried to implement the
answers into my particular situation but I am having no luck. Some help
would be greatly appreciated.
Query
SELECT `avatar` from `users` ORDER BY ABS(`avatar`) ASC;
Result
+--------------------------------+

| 2/12_wefwefwef.jpg |
| 2/1_default.jpg |
+--------------------------------+
I tried to sort by ABS and columns but unless I made a new column or a
dedicated table, I cannot find a way to sort this the way I want it to.
Essentially, I want to sort it numerically and a desired outcome would be
something like:
Desired result
0/1
1/3
1/25
1/122
1/321
2/1
2/12
From the searches on SO, I know there is the SUBSTR function but with the
'/' in the middle, I am not sure how I can get it to sort properly.

How to bind a dynamically created object to the document ready event?
How to bind a dynamically created object to the document ready event?
I have a function that dynamically creates a slider element using the
following code:
function NewDiv(){
for (var count=0; count < parseFloat(sessvars.storey_count); count++)
{
var string="<br><div id='my-slider"+count+"'
class='dragdealer'><div class='red-bar handle'><span
id='drag-button"+count+"'>drag me</span></div></div>";
$("body").append(string);
var slider_id ="my-slider"+count;
var drag_button_id = "drag-button"+count;
//OBJECT GETS CREATED BELOW
new Dragdealer(slider_id,{horizontal:
true,x:Math.random(),animationCallback: function(x, y){
document.getElementById(drag_button_id).innerHTML =
x.toFixed(2);
}
});
}
}
However, the animationCallback function which is invoked everytime the
slider is moved has to be embedded within a function listener, and I have
to somehow bind it to maybe the ready event. Is this the best way to make
the slider update when its value changes? And if so, how do I go about
doing this?

I made this test code to test this plugin, but can't seem to get it to
work, any ideas why? It does not add the -'s in like masked input should.

Layering UIImageView and UIBezierPath
Layering UIImageView and UIBezierPath
I have a an array of UIBezierPaths which I drew and also a UIImageView all
put on a UIView. When I draw a UIBezierPath and save it to the array, then
add a UIImageView, then draw another path, the second path will appear
behind the image. Is there something such as a bringSubViewToFront sort of
thing for UIBezierPath?

Pyglet window will not redraw on resize
Pyglet window will not redraw on resize
I have a class that is subclassed to pyglet.window.Window, and I need it
to be a resizable window. I figured out how to enable it to be resized,
but I need to make it redraw everything on the screen when I actually do
resize it. Here's what I have so far:
if __name__ == '__main__':
window = Application()
@window.event()
def on_resize(x,y):
window.label.x = window.WindowSize[0]/2
window.label.y = window.WindowSize[1]*15/16
@window.event()
def on_draw():
window.clear()
window.label.draw()
for control in window.controls:
control.draw()
pyglet.app.run()
so we make our window and then have those two window events. I hope I did
that right--I'm fairly new to pyglet. As I said, the main problem is that
when I resize the window it doesn't actually change anything unless I
press one of the buttons on the window which changes the positions.

Cocos2d - scheduled selector never called
Cocos2d - scheduled selector never called
For some reason one of the methods I'm scheduling isn't getting called.
The class's parent's parent inherits from CCNode. The class's parent has a
method called resetCoolDown like this:
- (void) resetCoolDown:(ccTime)dt {
_onCoolDown = false;
}
I schedule like this:
[self scheduleOnce:@selector(resetCoolDown:) delay:1];
There are no issues scheduling the selector, but for some reason
resetCoolDown is never called.
Am I doing something wrong?

Flyway seems to not be overriding properties
Flyway seems to not be overriding properties
I have my standard flyway config in my pom file and I am trying to
override in through system properties, as mentioned here.
Here is my configuration in the pom file:
<plugin>
<groupId>com.googlecode.flyway</groupId>
<artifactId>flyway-maven-plugin</artifactId>
<version>2.1.1</version>
<configuration>
<url>dbUrl</url>
<user>dbUser</user>
<password>dbPass</password>
<schemas>
<schema>core</schema>
<schema>public</schema>
</schemas>
</configuration>
</plugin>
And following is the command line that I'm running:
mvn clean compile flyway:migrate -Dflyway.url=anotherDbUrl
-Dflyway.user=anotherDbUser -Dflyway.password=anotherDbPass
The documentation in the above link says System properties > Maven
properties > Plugin configuration. Am I missing something?
