How to simulate dynamic requests per minute in JMeter where numbers come
from file for each minute
After successfully using JMeter to profile our platform's performance I
got the request to simulate a 24h load based on minute-by-minute
transaction data extracted from the last year's logs.
At this point, having the static nature of thread creation in jmeter I am
wondering if this is easily achievable. I studied the usual plugins
together with those at jmeter-plugins.org but still I could not find a
straightforward way to do this kind of shaping.
I am looking at the alternative to write a groovy script that takes
control of thread creation but I am not sure if this is the proper way to
go.
Any suggestions?
Thanks, Dikran

AHK utilman script gives file not found error
AHK utilman script gives file not found error
I'm trying to create a simple backdoor for myself through utilman on my
computer using autohotkey. Basically I want to have the ease of access
button function normally in all cases on login screen Except when I hold
down the M key, where in this case it opens cmd instead. No batch or cmd
window should pop up, and one doesn't. The issue I'm having is that I get
a file not found error from the script, I compiled the script into
Utilman.exe and tested with a copy of the real utilman (renamed to lol.exe
which is specified in the script to run normally) and this works fine in
its own directory. However when I do this in the system32 folder it gives
an error that lol.exe is not found, also executing lol.exe on it's own
gives the exact same error, as if it reroutes to the script named Utilman
yet again. Here is the script, should be short and simple:
SetWorkingDir %A_ScriptDir%
Sleep 400
GetKeyState, state, m
if state = D
Run cmd.exe
else
Run lol.exe
Sleep 200
ExitApp
Thanks for any pointers, alternative suggestions or ideas. This would be
great to get working.
EDIT: Changing Run lol.exe to Run, "C:\Windows\System32\lol.exe" now gives
instead an exe corrupted error. This also happens if I run lol.exe on it's
own, I'm really not sure what's happening.

Two vertical child elements need to fit 100% height of parent, both dynamic heights
Two vertical child elements need to fit 100% height of parent, both
dynamic heights
I have a feeling that this might not be possible, but I'm hoping someone
will prove me wrong.
I have a parent element of a non-fixed height (although it could be, I
don't think it helps). Within it are two children, stacked vertically. The
height of the first item is unknowable. I'd like the second item to take
up the remaining height.
HTML:
<div class="container">
<a class="snippet" href="#">
<img class="example-image" src="example-image.png">
<div class="snippet-text-section">
<div class="snippet-title">Title for the item - could be one or two
lines long</div>
<div class="snippet-text">Rest of the text, filling the remaining
space.</div>
</div>

Please note I've looked at a lot of posts on here. Most similar ones deal
with the child divs having a horizontal layout. The closest I've come to a
solution (and what I'm currently using) is Two vertical divs within a 100%
height div where I'm forcing the height of the first child, but it's not
ideal.
I'm currently wondering if there's a table-layout solution I've missed...

Doctrine many to one relation with no additional key
Doctrine many to one relation with no additional key
I've made some projects with many-to-one/many relations, foreign keys etc
in doctrine and they all worked well. At least as long as I could join
them by id and some other index.
This time I have a table with invoices and another table with company
addresses etc. A simplified Invoice.orm.yml looks like this:
uniqueConstraints:
event_user_idx:
columns: seller,number
manyToOne:
companyData:
targetEntity: CompanyData
joinColumns:
seller:
referencedColumnName: vatNo
fields:
id:
type: integer
id: true
generator:
strategy: AUTO
seller:
type: string
length: '16'
number:
type: string
length: '32'
while CompanyData.orm.yml looks like this:
indexes:
nip:
columns: [ nip ]
fields:
id:
type: integer
id: true
generator:
strategy: AUTO
name:
type: string
length: '128'
vatNo:
type: string
length: '16'
Usually I would just add a new field to Invoices, like 'company_id' and
everything would (most likely) work well. However, as vatNo is a unique
number (as there are no two companies with the same vat number) I don't
want to create necessary artificial keys. So I've made a unidirectional
many-to-one mapping as above. Everything works well when I get data from
the database. I can make a query like this:
SELECT f, c
FROM MyBundle:Invoices i
LEFT JOIN i.companyData c
WHERE f.seller = :seller
and get all the invoices with companies related to it. However, there's a
problem with adding new entities to the database - after adding a foreign
key, I can no longer change the 'seller' field. I tried
$invoice->setSeller('some string')
and
$invoice->setCompanyData($companyData) //some CompanyData object fetched
from DB
it is set to null anyway. While 'seller' is not nullable, I get an exception.
I've tried to change the mapping to:
manyToOne:
companyData:
targetEntity: CompanyData
joinColumns:
seller_other_column:
referencedColumnName: vatNo
and then the query was successful, but the seller_other_column was set to
null anyway. Another strange thing is that when I call
echo $invoice->getSeller();
print_r($invoice->getCompanyData());
$em->persist($invoice);
$em->flush();
it displays the proper data (vat number and CompanyData object), but these
data are nulled anyway, before saving to the database.
Do you have any idea what's wrong?

How to configure DNS nameservers for Ubuntu cloud machines non-interactively?
I want to setup custom nameservers for my Ubuntu cloud instances (which

If I try to set it in /etc/network/interfaces it works, but this would is
not friendly to script. Is there a easier way to script this so that the
setting remains persistent across reboots?

Sufficient and necessary conditions to get an infinite fiber $g⁻©ö(w)$
Sufficient and necessary conditions to get an infinite fiber $g⁻©ö(w)$
I want to verify the proof of this result and get some start ideas to
overcome the different steps of this proof.
Lemma: Let $g$ be a real analytic function. Then we have the equivalence
$((a)¡ü(b))¢¢(c)$, where the statements $(a),(b)$ and $(c)$ are given by:
(a) $g$ has infinitely many real zeros.
(b) $g$ assumes arbitrarily large and arbitrarily small values, i.e., for
all $K>0$, there are $s©û,s©ü$ with $g(s©û)<-K$ and $g(s©ü)>K$,
(c) The fiber $g⁻©ö(w)$ is infinite for all $w¡ôℝ$.
Proof: (1) To prove that $(a)¡ü(b)¢¡(c)$, assume by contraduction that the
equation $g(s)=w$ has only finitely many solutions $(b_{j})_{1¡Âj¡Âi}$.
That means there are $z©û<z©ü$ such that $g(s)¡Áw$ for $w<z©û$ or $w>z©ü$.
Let $z©ý$ be the largest zero of $g$ smaller than $z©û$, and $z©þ$ the
smallest zero larger than $z©ü$. The exitence of $z©ý$ and $z©þ$ is
guaranteed by the premises that $g$ has infinitely many zeros and the fact
that $g$ is analytic, so $g$ has only finitely many zeros in the compact
interval $[z©û,z©ü]$ (or $g$ is identically $0$, but that has been ruled
out by the premise that it take arbitrarily large values), hence there
must be infinitely many outside the interval. Let
$K=max({|g(s)|:z©ý¡Âs¡Âz©þ})+|w|$. By assumption, there are $s©û,s©ü$ with
$ g(s©û)<-K$ and $g(s©ü)>K$. By the intermediate value theorem, there is
an $s_{w}$ between $z©ý$ or $z©þ$ and $s©û$ or $s©ü$ with $g(s_{w})=w$.
Contradiction.
We note that if $g$ is not analytic then it satisfies conditions (a) and
(b) but does not satisfy (c).
(2) To prove that $(c)¢¡(a)¡ü(b)$, we note first that $g$ has infinitely
many zeros because the fiber $g⁻©ö(0)$ is infinite. This proves item
(a). To prove item (b), let $K>0$ and $w=K+¥å,¥å>0$. The fiber
$g⁻©ö(K+¥å)$ is nonempty because it is infinite, hence there is
$s©ü$ such that $g(s©ü)=w=K+¥å>K$. By the same method, $g⁻©ö(-K-¥å)$
is nonempty, so there is $s©û$ such that $g(s©û)=-K-¥å<-K$.

overcome the different steps of this proof.

That means there are $z©û<z©ü$ such that $g(s)¡Áw$ for $w<z©û$ or $w>z©ü$.
Let $z©ý$ be the largest zero of $g$ smaller than $z©û$, and $z©þ$ the
smallest zero larger than $z©ü$. The exitence of $z©ý$ and $z©þ$ is
guaranteed by the premises that $g$ has infinitely many zeros and the fact
that $g$ is analytic, so $g$ has only finitely many zeros in the compact
interval $[z©û,z©ü]$ (or $g$ is identically $0$, but that has been ruled
out by the premise that it take arbitrarily large values), hence there
must be infinitely many outside the interval. Let
$K=max({|g(s)|:z©ý¡Âs¡Âz©þ})+|w|$. By assumption, there are $s©û,s©ü$ with
$ g(s©û)<-K$ and $g(s©ü)>K$. By the intermediate value theorem, there is
an $s_{w}$ between $z©ý$ or $z©þ$ and $s©û$ or $s©ü$ with $g(s_{w})=w$.
Contradiction.
We note that if $g$ is not analytic then it satisfies conditions (a) and
(b) but does not satisfy (c).
(2) To prove that $(c)¢¡(a)¡ü(b)$, we note first that $g$ has infinitely
many zeros because the fiber $g⁻©ö(0)$ is infinite. This proves item
(a). To prove item (b), let $K>0$ and $w=K+¥å,¥å>0$. The fiber
$g⁻©ö(K+¥å)$ is nonempty because it is infinite, hence there is
$s©ü$ such that $g(s©ü)=w=K+¥å>K$. By the same method, $g⁻©ö(-K-¥å)$
is nonempty, so there is $s©û$ such that $g(s©û)=-K-¥å<-K$.

In UCP, Is SCTS Field is really consistent between ot-51 ack and ot-53
request?
I've been trying to implement a mechanism that communicates with smsc
using the ucp(emi) protocol. on top og that, i was trying to implement a
CDR mechanism, based on three steps: tcp ack, ot-51 ack message and ot-53
notification message. According to the EMI documentation, the SCTS field
should be consistent with the timestamp recieved in the ot-51 ack. i've
noticed that those values are not always consistent, did anyone else came
by this problem? can it be an smsc configuration problem?
thanx in advance :)

How should I communicate with a server?
How should I communicate with a server?
Imagine some fellow wants to query a pizza server for the list of pizzas.
This individual would do simply
GET /pizzas
;=> ["cheese", "extra cheese", "broccoli"]
With pedestal-app's data model and messages, I am not sure how to design
client-server communication. Here are the possibilities some minutes of
hammocking brought:
An effect-consumer that
transforms a message into an HTTP request
transforms back the results (to e.g. [{:type :add :topic [:pizzas] :value
"cheese"} ...])
puts the messages in the queue
A dedicated resource on the server (e.g. "/edn") that
accepts pedestal messages
dispatches to the right function
responds with the raw data (i.e. ["cheese", "extra cheese", "broccoli"])
has the effect-consumer transform back the results to messages
A dedicated resource that uses the routes. Just like #2, but
altering the request
forwarding it to another entry in route table
Messages on both sides, with
the server transforming messages into function calls
the server transforming results back into messages
the client just adding these messages to the queue
It seems to me that with approaches #2 and #4, I'd bypass and lose all the
benefit of the interceptors. With approach #2, I'd need to redouble the
routing logic. With approach #4, I'd also need to generate a lot of code
to accommodate the pedestal client.
Options #1 and #3 seem better, but #3 smells hacky and #1, misdirected.
How are you guys doing it?
Thanks!

java socket buffer and string
java socket buffer and string
For a homework i try to send a file and some parameter corresponding to
this file. So, i send my file and after my string. The problem is my
paramater go to my file and not in my variable. I understand the problem,
my loop while continue to write in the file as long as he receives
something, but i want to stop it and have my parameter outside from my
file.
Here my code client:
public static void transfert(InputStream in, OutputStream out) throws
IOException{

int n;
while((n=in.read(buf))!=-1)
out.write(buf,0,n);

printOut.println("add");
System.out.println("envoie !!!");
printOut.println("1");
printOut.println("3");
// out.write(getBytes("add"),0,0);
printOut.flush();
}
and here my server code :

How to use a php restful api-centric design internal instead of with http request
How to use a php restful api-centric design internal instead of with http
request
Lang: php
Servers: Amazon e2/lamp
Database: MySQL
I am wanting to create a php restful api-centric web application/website.
Where as I have the data/api that gets called from my front end code.
Besides making HTTP/curl request calls each time I load a page, what can I
do for internal API calls using frameworks like slim.
I'm not sure of a way to include the api for internal use in my front end
code and still keep it apart.
My thoughts was something like this:
"example.com/api/story/todays-weather/"
pulls in the json formatted story with a http request with curl or Ajax
But instead could I do something like:
require("/api/internal.php");
$uri = "/story/todays-weather/";
$call = api::getStory($uri);
$result = json_decode($call);
.....
I'm a headed in the right direction or am I way off. =/
The api and front code are on the same cloud box and I am planing on using
memcached for the api.

Accordion on Sharepoint 2010 content query
Accordion on Sharepoint 2010 content query
I am now trying to implement the accordion function for a content query
webpart.
Basically, the content query structure looks like this: Title Content I
want to expand collapse <li class="dwft-item">
<div class="link-item"> Title </div>
<div class="description"> Content I want to expand collapse </div>
</li>
<li class="dwft-item">
<div class="link-item"> Title </div>
<div class="description"> Content I want to expand collapse </div>
</li>
<li class="dwft-item">
<div class="link-item"> Title </div>
<div class="description"> Content I want to expand collapse </div>
</li>
and I have 3-5 of them.
What I want to do now is to expand collapse the description div whenever I
click on the corresponding link-item (title) div.
Here is my JS code:
$(document).ready(function () {
//ACCORDION BUTTON ACTION
$('#MSOZoneCell_WebPartWPQ3 .link-item').click(function () {
//MAKE THE ACCORDION CLOSE ON THE SECOND CLICK
if ($('#MSOZoneCell_WebPartWPQ3 .description').hasClass('openDiv')) {
$('#MSOZoneCell_WebPartWPQ3 .description').toggle('normal');
$(this).next().removeClass('openDiv');
} else {
$('#MSOZoneCell_WebPartWPQ3 .description').toggle('normal');
$(this).next().toggle('normal');
$(this).next().addClass('openDiv');
}
});
//HIDE THE DIVS ON PAGE LOAD
$("#MSOZoneCell_WebPartWPQ3 .description").hide();
});
The problem I have now is that whenever I click on any one of the titles,
ALL the description div expands, which is not what I want because I want
only that particular description under the title I clicked to expand.
Any help here will be much appreciated here ! Thanks!!

Client Specific Localization
Client Specific Localization
Looking for advice for this tricky kind(for me!) of localization. We have
different client in our project and we are making localization for client
wise. Condition if client specific resx file is not available then it
should take the default resx language wise.
We have folder structure like this :-
LocalizationFolder
en-us folder
Client1Folder :- en-us client specific resx file
default resx file
We have tried using getglobalresourceobject and getlocalresourceobject
methods. These methods will go to till the last/deepest path in folder
structure. But it is not picking up the client specific resx file. We have
kept naming convention of resx file same for default and client specific
resx file.
Thats why it giving error as 'default.en-us.resx file already exist OR it
conflicts with other file'.
So my question how can i pick up the resx file based on client name and if
it is not present the pick up the default resx file.
Is this possible Or any different approach needs to be follow.

So my question how can i pick up the resx file based on client name and if
it is not present the pick up the default resx file.
Is this possible Or any different approach needs to be follow.

Dynamicaly alter django model's field return value
Dynamicaly alter django model's field return value
Let's say I have a setup similar to this:
class UnitsOfMeasure(models.Model):
name = models.CharField(max_length=40)
precision = models.PositiveIntegerField()
class Product(models.Model):
name = models.CharField(max_length=100)
uom = models.ForeignKey(UnitsOfMeasure)
qty_available = models.DecimalField(max_tigits=10, decimal_places=10)
Now lets say we have a product related to Units of measure instance with
precision = 2. How can I do that qty_available would return 5.50 instead
of 5.5000000000?
I know I can use property decorator, but this does not solve my problem,
since I want to use qty_available as a field in forms.
Custom Field type? How can I pass and access related model instance then??
Your ideas are very appreciated!

which is best option to publish android app with local database?
which is best option to publish android app with local database?
I am developing an app in which i would need a local database.
So as per my knowledge there are two ways to do it:
First is to add pre filled database file in assets folder & make copy of
local database from it the very first time app is started.
Second is using script to download it from Server for first time of app use?
First way have been pretty well answered by this guy Using your own sqlite
database in android application
Can someone help how can i go with second way of download data from Server?
Should i use JSON/XML for getting that data from my Server?
Or should i go with first option since my app has only around 150 to 200
rows in the db file?

PHP User Based Templating
PHP User Based Templating
Hi I'm creating a system where users can create their own themes, styles,
and templates. I'm storing their page templates in a mysql db and
currently I've written a small replace script that uses tags so the user
can define where content should go in their template elements. The script
replaces their tags with their content during when the page is rendered.
What I want to do now is add the ability for them to define a section
conditionally - so for example they might have an element in their
template that looks like this:
<h1 class="entry-title">
<span class="top-left-ribbon"></span>
@titlebar>heading
<span class="sub-heading">@titlebar>subheading</span>
<span class="right-ribbon"></span>
</h1>
Replacing the titlebar heading and subheading with the required values is
no problem, but I can't figure out how to do the following and replace the
conditionals with php if statements and have it process.
<h1 class="entry-title">
<span class="top-left-ribbon"></span>
@titlebar>heading
@titlebar?subheading
<span class="sub-heading" >@titlebar>subheading</span>
<span class="right-ribbon"></span>
@end?
</h1>
Basically I would want to replace
@titlebar?subheading
@end?
With...
if($titlebar->subheading){ }
And process through php appropriately.
Any suggestions would be appreciates.

Capturing global keystrokes in Objective C (OS X)
Capturing global keystrokes in Objective C (OS X)
I am quite new to Objective C and Xcode, and so I have experienced some
difficulty understanding how to implement advanced functionalities.
Requirements: Detect key presses (whether application window is in focus
or running in background) and execute some code depending on which keys
were pressed. Meant to function as hotkeys/shortcut keys.
KeyEvents in Cocoa and XCode appeared to contain potential solutions, but
I am uncertain as to whether the suggestions there are capable of
capturing key presses which occur outside of the application. I am also
not sure how exactly one would subclass the default NSView object created
by Interface Builder and tie it back to my NSWindow (also magically
created by Interface Builder) -- assuming something like this is required
at all. Not really sure how to refer from code to objects created by the
.xib, but that may be a separate question.
So, bottom line... if this is possible (without hackish OS security
overrides to enable keylogging), I would be interested to know exactly how
to go about it from the point of creating a new project in Xcode and
immediately trying to capture keystrokes.
Thanks

jQuery: Hide a field and mark it as valid
jQuery: Hide a field and mark it as valid
I have the following scenario:
I have a radio-group that hides or shows some input fields onchange which
works fine:
view.selectFormerHRInsurance.change(function() {
if ($(this).val() == true) {
view.sectionHRInsuranceName.show();
view.sectionHRInsuranceNumber.show();
view.sectionHRInsuranceSum.show();
view.sectionHRInsuranceStatus.show();
view.sectionHRInsuranceTerminationDate.show();
} else {
view.sectionHRInsuranceName.hide();
view.sectionHRInsuranceNumber.hide();
view.sectionHRInsuranceSum.hide();
view.sectionHRInsuranceStatus.hide();
view.sectionHRInsuranceTerminationDate.hide();
}
});
When a field is validated and there is an error, the error message appears
on the field and i show a global error message.
My problem is, that the global error message is still present, when i hide
the fields and as you can guess: i don't want that!
I want to "mark" the fields i hide as validated and validate it, when i
show them. How can i achieve this?

Console App that scans for changes in a directory past 24 hours
Console App that scans for changes in a directory past 24 hours
I'm creating a program that scans for changes, not create or delete, in
ALL the files in a given directory, and all of his sub directories, in the
past 24 hours. I've seen lots of other examples/tutorials but not all of
them do what I'm looking for.
This is my code so far:
using System.IO;
public static void Main(string[] args)
{
string myDirectory =
Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments),
@"C:\Path");
var directory = new DirectoryInfo(myDirectory);
DateTime from_date = DateTime.Now.AddDays(-1);
DateTime to_date = DateTime.Now;
var files = directory.GetFiles().Where(file =>
file.LastWriteTime >= from_date && file.LastWriteTime <=
to_date).ToArray();
Console.WriteLine();
}
The problem is that the code above only tells me the last change in the
directory. What I want is a log of all the changes in the directory.
I am a learning student, so lots of explanation would be great! :)
I am NOT, I repeat NOT, looking for FileSystemWatcher, I don't want my
server to stay on for 24 hours straight. I want to start this program once
every 24 hours, make a log, close it. If anyone can help me out with this,
or at least give me something to start with, I would very much appreciate
it!

Why are spurious SAX warnings appearing in my compilation?
Why are spurious SAX warnings appearing in my compilation?
I have a modest-sized multi-project solution written in C# which I am
developing using Microsoft Visual Studio 2010 on Windows XP. In the last
few days it has taken to reporting scores of warnings like the following:-
At least one of the arguments for 'ISAXXMLReader.getBaseURL' cannot be
marshaled by the runtime marshaler. Such arguments will therefore be
passed as a pointer and may require unsafe code to manipulate.
Similar warnings are produced for ISAXLocator, ISAXAttributes,
ISAXXMLFilter, and other apparently SAX related classes. I'm not using XML
at all anywhere in the project.
While this isn't a crippling problem, genuine warnings are getting lost in
the noise.
Does anyone know what the problem is, and what I can do about it?

Year() function and Month() function
Good Day Every one Currently im using this codes to get the data that are
with in a specific month
SELECT * from Table1 d
where
MONTH(d.fld_ExpiryDate)=@month
AND YEAR(d.fld_ExpiryDate)=@year
some of my colleagues told me to use the duration eg.
d.fld_LoanDate >= '2009-11-01' and
d.fld_LoanDate < '2009-12-01'
the question is would it be better to use the range?? and how would i
compute the start of the month and start of next month? if the users input
where just @month int and @year int?
any help would be greatly appreciated im new in tsql that's why i do not
know the work arounds and whats good or not in coding..
Thank You :)

jQuery Hide Class with Slide Transition
jQuery Hide Class with Slide Transition
I'm trying to collapse a vertical left bar with a slide transition. I
start with a larger width (250px), down to a smaller width (50px) toolbar
size.
I can hide/show the wide bar completely with a nice slide transition using:
$("#pnlLeftSide").hide('slide', {direction:'left'}, 300);
$("#pnlLeftSide").show('slide', {direction:'left'}, 300);
Or I can add a class to go from wide to mini, which basically hides a lot
of inner content and then displays a few smaller toolbar type things
using:
$("#pnlLeftSide").toggleClass("min");
But I can't go from wide to mini, with a nice smooth slide transition as
it collapses in size (width).
If I try this, it jerks at the end
$("#pnlLeftSide").hide('slide', {direction:'left'}, 300, function() {
$(this).addClass("min"); });
$("#pnlLeftSide").show('slide', {direction:'left'}, 300, function() {
$(this).removeClass("min"); });

Need to retrieve product descriptor string from USB device on WinXP
Need to retrieve product descriptor string from USB device on WinXP
I have used the code in this post to successfully read the USB product
string in the descriptor for a RNDIS device on Windows 7. I really need
the string from the original USB descriptor and not the one supplied in
the driver INF file. For example, I need to make a user-mode application
able to determine two slightly different products which are identical in
every way except the iProduct - indexed string descriptor. I know that
different products should have different idProduct fields but I have no
control over this.
However, I also need this to work on Windows XP, which apparently does not
support 'DEVPKEY_Device_BusReportedDeviceDesc'.
I believe it may be possible on XP by starting with the usbview project in
the driver development kit, but that looks like tons of work compared to
the relatively simple code referenced above. Does anybody know the easiest
way to get the product string from the USB device's descriptor for a
device which already has a driver installed which works on Windows XP?
The application is unmanaged C++.

plz find my map below.
where in my first script file i am checking if my reference type is equal
to A,B,C,D,E then only the rest of the elements should map to destination
schema, by doing that i am getting below output.
However i don't want to generate empty child tags. Could you please
suggest. I have checked some blogs where suggesting xslt, I have no idea
of xslt so want to do with functoid.

Javascript: Need to proceed to another page
Javascript: Need to proceed to another page
I'm using Javascript for deleting a record. But my problem is, when I
click the image button its not redirecting to the page I want instead it
will remain on the page...
Here's my code:
echo "<button type='submit' name='deletePlaylist[]' value='" .
$row['id']."' onClick='myFunction()' style='border: 0; background:
transparent; cursor: pointer;'><img src='image/delete.png' /></button> ";
I'm using the button because I'm using an image if I used the input its
not working... So I decided to use button
Here's my code in my javascript:
function myFunction()
{
var Xcancel;
var Rokay=confirm("Are you sure you want to delete?");
if (Rokay==true)
{
window.location = 'delete.php';
}
else
{
Xcancel="You pressed Cancel!";
}
}
</script>
I already tried the window.navigate("delete.php"); or the
window.location.href='delete.php' also not working...
The confirmation message is displaying already but my main problem its not
going to the delete.php where in that form is my deleting function...
NOTE:
The button is under of the <form name='form' method='post' action="">, the
delete.php is in the same folder... Before there is no confirmation
message and its going to the delete.php but now I tried to insert a
confirmation message then its not going to the delete.php
Thank you in advance,!

PHP string goes empty unless echoed
PHP string goes empty unless echoed
I have the following test program:
#!/usr/bin/php
<?php
echo "Starting\n";
# Now read the file.
#
$file_pn = "contact.txt";
$fh = fopen($file_pn, 'r');
while (!feof($fh)) {
$line = fgets($fh);
$trimmed = trim($line);
echo "trimmed = <" . $trimmed . ">\n";
if (preg_match('/^\s*$/', $trimmed)) {
echo "Looks blank: trimmed = <" . $trimmed . ">\n";
#continue;
}
}
fclose($fh);
?>
The file being read has some blank lines and some non-blank lines. As
shown here, it acts as one would expect: only the lines that are actually
blank receive the "Looks blank" message, and trimmed = <>. But if I
comment out the echo statement in line 12 and run the script again,
$trimmed always appears to be the empty string when we get to the if
statement. It is as if $trimmed gets clobbered unless it has been echoed.
How can this be?

How to run Dunnett C post hoc test in R?
How to run Dunnett C post hoc test in R?
I ran a two-way anova in r with my data set (unequal sample sizes, unequal
variance): 1 variable measured across 3 species (with males and females in
each species). This produces a significant result between species, so I
want to know which pairwise comparisons produce the significance. I know
that there are functions in packages for performing post hoc tests in R:
e.g.
Dunnett's post hoc test from
http://www.uwlax.edu/faculty/toribio/math305_fall09/multiple.txt
library(multcomp)
?glht
test.dunnett=glht(anova_results,linfct=mcp(method="Dunnett"))
confint(test.dunnett)
plot(test.dunnett)
But Dunett's test is designed to compare all groups to a control. Instead
I want to compare all groups to each other, the Dunnett C. Does anyone
know of a package that performs Dunnett C or knows how to code it?

Will the JVM detect orphaned cycles?
Will the JVM detect orphaned cycles?
"Orphaned cycles" may not be exactly the correct term for what I'm trying
to describe; I heard it from a co-worker, but it may have just been a
casual term. Here is an example of what I'm trying to describe in code:
public class Container {
private Container otherContainer;
public Container(Container otherContainer) {
this.otherContainer = otherContainer;
}
public void setContainer(Container otherContainer) {
this.otherContainer = otherContainer;
}
}
public class Main {
public static void main(String[] args) {
doStuff();
}
public static void doStuff() {
Container c1 = new Container(null);
Container c2 = new Container(c1);
c1.setContainer(c2);
// c1 and c2 now each hold a reference to each other; can they be
garbage-collected
// once this method exits?
}
}
Essentially, the question boils down to this - given a graph of references
containing a cycle, can the JVM collect the references once it would be
safe to do so, or is this a memory leak?

Social Plug-in and like button not working on Blogger
Social Plug-in and like button not working on Blogger
My blog is www.pqed.org
The social plugin was working fine until a couple of months ago. Now, it
says the data can't be scraped, the like button doesn't work, when I share
on Facebook, it doesn't give the title or the post image (just the URL and
sometimes a random image from the site). I removed it, but when I put it
in, sometimes it doesn't even show up.
I suspect there is a corrupt image but I can't find it. I have removed all
the widgets, reset the template, and tried everything.
If may also be an an absolute URL problem after the migration. Or it could
be both.
Please help. Will someone look at the code and see what's up?
I have spent maybe 100 hours on this and I think I've made it all worse
instead of better.
Thanks

This is one of the problems with cookie says the book
The book says "A user often opens many tabs in the same browser window. If
the user browses the same site from multiple tabs, all of the site's
cookies are shared by the pages in each tab. this could be problematic in
web applications that allow the user to parchase in each tab."
Can somebody explain what the book is trying to say because I don't really

Colossal memory usage/stack problems with ANTLR lexer/parser
Colossal memory usage/stack problems with ANTLR lexer/parser
I'm porting over a grammar from flex/bison, and mostly seem to have
everything up and running (in particular, my token stream seems fine, and
my parser grammar is compiling and running), but seem to be running into
problems of runaway stack/memory usage even with very small/moderate sized
inputs to my grammar. What is the preferred construct for chaining
together an unbounded sequence of the same nonterminal? In my Bison
grammar I had production rules of the form:
statements: statement | statement statements
words: | word words
In ANTLR, if I maintain the same rule setup, this seems to perform
admirably on small inputs (on the order of 4kB), but leads to stack
overflow on larger inputs (on the order of 100kB). In both cases the
automated parse tree produced is also rather ungainly.
I experimented with changing these production rules to have an explicitly
additive (rather than recursive form):
statements: statement+
words: word*
However this seems to have lead to absolutely horrific blowup in memory
usage (upwards of 1GB) on even very small inputs, and the parser has not
yet managed to return a parse tree after 20 minutes of letting it run.
Any pointers would be appreciated.

Big image on smaller JFrame/Applet
I have a pretty big image that I want to display on my JFrame and applet,
the JFrame/Applet is 765x503 in size but the image is way larger. I need a
way to display the image in real size. How can I make it so I can move the
screen around to display some of the image and be able to move around the
image?
I want to be able to drag the screen around, not use Scrollbars.

(Java) Looking for advise on the layout and process I have chosen for this task?
(Java) Looking for advise on the layout and process I have chosen for this
task?
I hope this is in the right place, if not my apologies but could someone
point me in a better direction? I've been working on this problem for 3
days now, Only 6 weeks into my first university class for any programming
at all and the first language we're learning is Java.
The problem is as follows:
Exercise Two (Another algorithm with sub modules)
Design an algorithm which will:
-Input the cost of a product and the amount the customer has tendered for
payment. you may assume that the payment is always > cost. You may also
assume that the cost and the amount paid are always in increments of 5
cents.
The algorithm should:
-Calculate the amount of change required.
-Determine the notes and coins to be given to the customer. -Output both
to the user.
I have made multiple attempts at this and scrapped my code multiple times,
I'm not looking for a solution from anyone, I've put enough into this to
hold out for that, but I am after some commentary on whether or not I am
going in right direction or if not a pointer as to where, also any comment
on the comments I've added to the code would be greatly appreciated.
Thanks for even taking the time to read this and a huge thanks to anyone
that can give me a hand. Cheers everyone

task?
I hope this is in the right place, if not my apologies but could someone
point me in a better direction? I've been working on this problem for 3
days now, Only 6 weeks into my first university class for any programming
at all and the first language we're learning is Java.
The problem is as follows:
Exercise Two (Another algorithm with sub modules)
Design an algorithm which will:
-Input the cost of a product and the amount the customer has tendered for
payment. you may assume that the payment is always > cost. You may also
assume that the cost and the amount paid are always in increments of 5
cents.
The algorithm should:
-Calculate the amount of change required.
-Determine the notes and coins to be given to the customer. -Output both
to the user.
I have made multiple attempts at this and scrapped my code multiple times,
I'm not looking for a solution from anyone, I've put enough into this to
hold out for that, but I am after some commentary on whether or not I am
going in right direction or if not a pointer as to where, also any comment
on the comments I've added to the code would be greatly appreciated.
Thanks for even taking the time to read this and a huge thanks to anyone
that can give me a hand. Cheers everyone

Which is more efficient recursion or loops?
Which is more efficient recursion or loops?
I am curious which is more efficient for iteration. I am using one to
break up a parse a string into a List. Is recursion more CPU efficient or
is looping? Is either more memory efficient? By looping, I am referring to
for, for each, do while, while, and any other types. Out of these loops
which are more efficient? Or are they all equally? Just curious.

Using Selenium Webdriver how to connect remote database and run test cases from local machine through eclipse
Using Selenium Webdriver how to connect remote database and run test cases
from local machine through eclipse
I am using selenium web driver java built , editor is eclipse. For testing
one of our website I am using Data driven testing by fetching data from
MySQL database.
I dumped the development server database to my local machine and installed
that dumped data in my machine xampp and able to connect to database and
proceed through the testing process.
To connect to my local machine database i am using this connection string
String url1 ="jdbc:mysql://localhost:3306/databasename";
String dbClass = "com.mysql.jdbc.Driver";
Class.forName(dbClass).newInstance();
Connection con = DriverManager.getConnection(url1, "root", "");
Statement stmt = (Statement) con.createStatement();
Now I need to connect to connect to our original development server
database which is in remote server.
Can any one suggest me how to connect to the remote server database and
what changes are needed to be done in the connection string ? what to put
in the host name ? and how I can run my test cases from my local machine
while connecting to remote server database.
Please provide some suggestion

Bitwise memmove
Bitwise memmove
Is their any implementation available for performing a bitwise memmove?
The method should take an additional destination and source bit-offset and
the count should be in bits too.
I saw that ARM provides a non-standard _membitmove, which does exactly
what I need, but I couldn't find it's or any similar method's source.

heroku restart via new API
heroku restart via new API
I'm a bit confused, as there used to be a method in heroku API to restart
processes of an app. Now this API seems to be deprecated and all links are
leading to https://devcenter.heroku.com/articles/platform-api-reference
where I cannot find any information about restart (even the word restart
itself).
Can someone shed some light on it? This is, I believe, along with showing
logs, one of the most important API commands for a dev, as you can do most
of other tasks via heroku webui.

Dynamic Div Content with just clicking one link/button
Dynamic Div Content with just clicking one link/button
I need help here please.
I want to show dynamic content to a div. I already have the code below:
<script type="text/javascript"><!--
function ReplaceContentInContainer(id,content) {
var container = document.getElementById(id);
container.innerHTML = content;
}
//--></script>
<div id="example1div" style="padding:10px; text-align:left;">
<p>Content 1</p>
</div>
<p align="center"><a
href="javascript:ReplaceContentInContainer('example1div','<p>Content
2</p>')">View another</a></p>
What it does is, when click the "View another" it replace the 'Content 1'
to 'Content 2' but what I want here is that, when 'Content 2' is already
shown, I want to click the "View another" link again and replace the div
content again with the new content like 'Content 3'.
Anyone please help me solve this.
Thanks in advance :)

Cakephp Upload plugin allows any file extension to be uploaded despite validation rules
Cakephp Upload plugin allows any file extension to be uploaded despite
validation rules
'model' => array(
'rule' => array('isValidExtension', array('xls')),
'message' => 'File does not have a stl extension'
),
Allows absolutely any file to be uploaded. I have this is as my first
validation rule. Other validation rules like notEmpty, and isUnique work
fine on the same form element.
Tried adding stl to the array found in the main behavior: 'extensions' =>
array('xls') - also did not work.
Any idea on what I'm doing wrong here?
Also: This appears to happen regardless of the file extension I pick. No
matter what, it doesn't call the file invalid. The same issue appears to
happen with Mime types as well.

How can I catch an exception and show proper error to user that there is
no arguments passed?
In my program I pass an argument from console and save it to a variable.
Let's say
const string FileName= argv[1];
If there is no argument passing I get this
terminate called throwing an exception
How can I catch an exception and show proper error to user that there is
no arguments passed?

How to exit SurfaceView?
How to exit SurfaceView?
I draw something on canvas using SurfaceView. How can I define a way to
cancelling the surfaceView once the user is done? Below is my SurfaceView
implementation. The DrawOnTop class has the onDraw() but I initialize all
the variables in Preview class.
public class Preview extends SurfaceView implements SurfaceHolder.Callback {
SurfaceHolder mHolder;
DrawOnTop mDrawOnTop;
boolean mFinished;
Preview(Context context, DrawOnTop drawOnTop) {
super(context);
mDrawOnTop = drawOnTop;
mFinished = false;
// Install a SurfaceHolder.Callback so we get notified when the
// underlying surface is created and destroyed.
mHolder = getHolder();
mHolder.addCallback(this);
mHolder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);
}
public void surfaceCreated(SurfaceHolder holder) {
//I set the bitmaps etc here
mDrawOnTop.mBitmap = Bitmap.createBitmap(mDrawOnTop.mImageWidth,
mDrawOnTop.mImageHeight, Bitmap.Config.ARGB_8888);
mDrawOnTop.mBitmap.setPixels(mDrawOnTop.mRGBData, 0,
mDrawOnTop.mImageWidth, 0, 0, mDrawOnTop.mImageWidth,
mDrawOnTop.mImageHeight);
mDrawOnTop.invalidate();
}
public void surfaceDestroyed(SurfaceHolder holder) {
mFinished = true;
}
public void surfaceChanged(SurfaceHolder holder, int format, int w,
int h) {
}
}

Matching numbers inside nested numbered groups
Matching numbers inside nested numbered groups
I am trying to find and capture all numbers inside ( and ) separately in
my data, ignoring the rest of the numbers.
My data looks like this
21 [42] (12) 19 25 [44] (25 26 27) 17 (14 3) 8 1 6 (19)
So I want to find matches for 12, 25, 26, 27, 14, 3 and 19
I tried doing \((\d+)\)* but this only gives me 12, 25, 14, 19
Any help is appreciated.

Apache/WordPress Cache Not Refreshing On My IP
Apache/WordPress Cache Not Refreshing On My IP
So I was trying out a caching plugin on my WP site. I had installed it
after my home page never changed (forever static). Uninstalled the plugin,
tried moving the WP files to another sub-domain, and my frontpage still
was static. Even on another sub-domain. This only had happened when I
changed some .htaccess settings for it, but I had already reverted these.
I've tried emptying my local cache. Page is still static. Does anyone know
what is going on?
I also figured out, it only is that page on my IP. And only that page.
Doesn't matter if the file exists, still makes the same old page show up.
Any help?

Micro-optimization of IF statement
Micro-optimization of IF statement
I always look into how to optimize the code more and more every day, and
how I can learn to code faster code.
Looking at some minified JS online I notice the change of a few IF into a
statement and I thought that it might be a very good idea to start using
it in PHP as well.
<?php
if(!isset($myVar) || $myVar == 'val'){
$myVar = 'oldVal';
}
if(isset($myVar) && $myVar == 'oldVal'){
$myVar = 'newVal';
}
?>
into
<?php
(!isset($myVar) || $myVar == 'val') && $myVar = 'oldVal';
isset($myVar) && $myVar == 'oldVal' && $myVar = 'newVal';
?>
As I like the new syntax, I started to use it more and more thinking to
save processing time, but do I really save any or there is no difference
internally between the two ?
(The example code is just an EXAMPLE to only show the technique)

Load JPEG image into a BlobField
Load JPEG image into a BlobField
I would like load JPEG image into a blob field, is it possible? I search a
lot but I don't find a clear answer.
I use this code:
var
BlobField : TBlobField;
Stream : TMemoryStream;
begin
BlobField := ClientDataSet1.FieldByName('image');
// Img is TImage and contain a JPEG image
Img.Picture.Graphic.SaveToStream(Stream);
Stream.Position := 0;
BlobField.LoadFromStream(Stream); // <-- Error: "Bitmap image is not
valid"
I have to use bitmap image?

Is `a
Is `a
I was curious to see if I could use this a<b<c as a conditional without
using the standard a<b and b<c. So I tried it out and my test results
passed.
a = 1
b = 2
c = 3
assert(a<b<c) # In bounds test
assert(not(b<a<c)) # Out of bounds test
assert(not(a<c<b)) # Out of bounds test
Just for good measure I tried more numbers, this time in the negative
region. Where a, b, c = -10, -9, -8. The test passed once again. Even the
test suit at a higher range works a, b, c = 10, 11, 12. Or even a, b, c =
10, 20, 5.
And the same experiment done in C++. This was my mentality going into it:
#include <iostream>
using namespace std;
int main()
{
int a,b,c;
a=10;
b=20;
c=5;
cout << ((a<b<c)?"True":"False") << endl; // Provides True (wrong)
cout << ((a<b && b<c)?"True":"False") << endl; // Provides False
(proper answer)
return 0;
}
I originally though that this implementation would be invalid since in
every other language I have come across would evaluate a boolean before it
would reach c. With those languages, a<b would evaluate to a boolean and
continuing the evaluation, b<c, would be invalid since it would attempt to
evaluate a boolean against a number (most likely throwing a compile time
error or falsifying the intended comparison). This is a little unsettling
to me for some reason. I guess I just need to be reassured that this is
part of the syntax. It would also be helpful to provide a reference to
where this feature is provided in the Python documentation so I can see to
what extent they provide features like this.

Does cout object remain a single instance, i.e. it never gets copied?
Does cout object remain a single instance, i.e. it never gets copied?
Is cout ever copied implicitly?
For example, is the cout object passed to the second overloaded operator
in the code below, and the cout object inside its implementation are the
same objects or is one a copy of cout?
My understanding is that the first implementation is correct because the
<< operator works for any ostream object, e.g. it will work for ofstream
objects for writing to files.
//First implementation
ostream& operator<<(ostream& os, const Date& dt)
{
os << dt.mo << '/' << dt.da << '/' << dt.yr;
return os;
}
//Second implementation
ostream& operator<<(ostream& os, const Date& dt)
{
cout << dt.mo << '/' << dt.da << '/' << dt.yr;
return cout;
}
//using second implementation on object date
cout<<date;

Creating reusable Django models
Creating reusable Django models
Having some trouble designing an application using Django models. More
specifically, I am trying to decide in which application a given model
should go.
A good example would be with a model where different analyses would be
performed on an object. For example, if I were doing an analysis on the
efficiency of a prostitution ring, I would have three models: Pimp, Whore,
and Client:
The pimp object would have a "stable" attribute which represents the
one-to-many relationship between the Pimp and his whores.
The Whore object would have a many-to-many relationship with the Client
object, or, there would be an additional "Trick" object, representing the
relationship between Whores and Clients.
If I wanted to analyze these objects in one way, i.e. seeing each whore's
percent time "occupied", this would be one simple application. But what if
I wanted to do additional analysis on these objects, i.e. see what whores
are the most "in demand"? It would make sense to me that each kind if
analysis belongs to an individual app, but then to which app do these
common objects belong?
Is there a common place where these common models should be stored? Should
all analyses be contained in one app?

printDialog = new Ext.Window({
title: "Print Preview",
width: 500,
autoHeight: true,
items: [{
sourceMap: mapPanel,
printProvider: printProvider,
xtype: "gx_printmappanel",
// use only a PanPanel control
map: {controls: [new OpenLayers.Control.PanPanel()]}
}],
bbar: [{
text: "Create PDF",
handler: function(){ printDialog.items.get(0).print(); }
}]
});
printDialog.show();
}
}]
});
I have tried using without ext.js but was not able to get how to pass the
map div as parameter,so i used the geoext but that was giving the above
exception.

I have downloaded the war file of the mapfish print osm and deployed it in
the tomcat, and used the js files from
http://api.geoext.org/1.1/examples/print-preview-osm.html, but i'm having
an exception
org.mapfish.print.InvalidJsonValueException: spec.layers[0].type has an
invalid value: OSM
is it the right way to do to print the map or can anybody point me in
right direction..my code is:
Ext.onReady(function() {
// The PrintProvider that connects us to the print service
var printProvider = new GeoExt.data.PrintProvider({
url: "http://localhost:8000/print-servlet-1.1/pdf/print.pdf",
method: "GET", // "POST" recommended for production use
capabilities: printCapabilities, // provide url instead for lazy loading
customParams: {
mapTitle: "OSM Printing",
comment: "This demo shows how to use GeoExt.PrintMapPanel with OSM"
}
});
var map = new OpenLayers.Map();
map.addLayer(new OpenLayers.Layer.OSM());
var lonLat = new OpenLayers.LonLat( userLon ,userLat ).transform(
new
OpenLayers.Projection("EPSG:4326"), //
transform from WGS 1984
map.getProjectionObject() // to
Spherical Mercator Projection
);
var zoom=10;
var markers = new
OpenLayers.Layer.Markers( "Markers" );
map.addLayer(markers);
markers.addMarker(new
OpenLayers.Marker(lonLat));
map.setCenter (lonLat, zoom);
// A MapPanel with a "Print..." button
mapPanel = new GeoExt.MapPanel({
renderTo: "content",
width: 1000,
height: 800,
map: map,
zoom: 10,
bbar: [{
text: "Print...",
handler: function(){
// A window with the PrintMapPanel, which we can use to adjust
// the print extent before creating the pdf.
printDialog = new Ext.Window({
title: "Print Preview",
width: 500,
autoHeight: true,
items: [{
sourceMap: mapPanel,
printProvider: printProvider,
xtype: "gx_printmappanel",
// use only a PanPanel control
map: {controls: [new OpenLayers.Control.PanPanel()]}
}],
bbar: [{
text: "Create PDF",
handler: function(){ printDialog.items.get(0).print(); }
}]
});
printDialog.show();
