AngularJS - Why select drop down doesn't have $event on change
I am newbie to AngularJS. I have a question, why does select doesn't
passes the $event?
HTML
<div ng-controller="foo">
<select ng-model="item" ng-options="opts as opts.name for opts in
sels" ng-change="lstViewChange($event)"
ng-click="listViewClick($event)"></select>
</div>
Script
var myApp = angular.module('myApp', []);
angular.element(document).ready(function() {
angular.bootstrap(document, ['myApp']);
});
function foo($scope) {
$scope.sels = [{id: 1, name: 'a'}, {id: 2, name: 'b'}];
$scope.lstViewChange = function($event){
console.log('change', $event);
}
$scope.listViewClick = function($event){
console.log('click', $event);
}
}
Have a look at this fiddle http://jsfiddle.net/dkrotts/BtrZH/7/. Click
passes a event but change doesn't.

How can I download a file from Google Drive?
How can I download a file from Google Drive?
I have been searching non-stop for this and have not found the answer. I
have a text file uploaded to Google Drive and want my VB application to
download it. I have tried the 'My.Computer.Network.DownloadFile' method
which downloads the html file of the file which says you are being
redirected (as google drive download link redirects you to a unique link
which expires after a period of time) and I have tried the WebClient
method which does not download the file at all. The url is along the basis
of: https://docs.google.com/uc?export=download&id=THEfileID. When I search
for the way to download from google drive on Google people say to look at
the Google drive api but I do not understand that at all. If you need any
additional information please ask. Thanks, zacy5000
Additional information: The link is not a direct download link but a link
that will redirect you to a temporary download link. I need it to download
WITHOUT being logged in to a account (the file is set to 'With url only'
in the sharing properties and it is a plain txt file.

Using exceptions for control flow
Using exceptions for control flow
I have read that using exceptions for control flow is not good, but how
can I achieve the following easily without throwing exceptions? So if user
enters username that is already in use, I want to show error message next
to the input field. Here is code from my sign up page:
public String signUp() {
User user = new User(username, password, email);
try {
if ( userService.save(user) != null ) {
// ok
}
else {
// not ok
}
}
catch ( UsernameInUseException e ) {
// notify user that username is already in use
}
catch ( EmailInUseException e ) {
// notify user that email is already in use
}
catch ( DataAccessException e ) {
// notify user about db error
}
return "index";
}
save method of my userService:
@Override
@Transactional
public User save(User user) {
if ( userRepository.findByUsername(user.getUsername()) != null ) {
LOGGER.debug("Username '{}' is already in use", user.getUsername());
throw new UsernameInUseException();
}
else if ( userRepository.findByEmail(user.getEmail()) != null ) {
LOGGER.debug("Email '{}' is already in use", user.getEmail());
throw new EmailInUseException();
}
user.setPassword(BCrypt.hashpw(user.getPassword(), BCrypt.gensalt()));
user.setRegisteredOn(DateTime.now(DateTimeZone.UTC));
return userRepository.save(user);
}

Script to detect and record network statistics?
Script to detect and record network statistics?
I am new to scripting, I have a requirement to write scripts to be used on
my MacBook pro to record data usage on my broadband connection.
My Requirements
The script should detect Internet connection is via dongle or wifi
If via dongle then record number of bytes sent and received upon every
connection
It should log to a file at regular interval
If possible summarise total number of bytes sent and received may be once
in a day from 6 am to 6am. (it can also summarise upon next start of the
system ..next start of the system could be at 10am...but once summarised
should not be considered for next run)....Or Once a month
Able to figure out total bandwidth usage ....for a month...
My question is... On Mac...which script language would be better?...Apple
script's, or shell script or using python...etc...
If possible please provide pointers for the same. Thanks in Advance

FFT returns large values which become NaN

I'm using a FFT class to get the fundamental frequency. I'm passing an

NaN. Im using below FFT class and I'm confused in where is the problem.

java.net.ProtocolException: Connection already established ( Not Found

In one of my android app, i am getting error "java.net.ProtocolException:

"Connection already established" exception in HttpsURLConnection for
solution but not useful)
Below is my code to call API. Code is working for all the API except the

throwing error for that API.

Pythonic way to specify comparison operators?
Pythonic way to specify comparison operators?
I am looking for some advice for the most pythonic (readable,
straightforward, etc) way to specify comparison operators for later use in
comparisons (to be executed via javascript). Something like (this is just
one example implementation that comes to mind - there are lots of other
possible formats):
comparisons = (('a', '>', 'b'), ('b', '==', 'c'))
which would later be evaluated like: (EDIT: this actually not how it will
get evaluated. It will be evaluated in Javascript, not python - read on
for details.)
if a > b:
do something...
if b == c:
do another thing...
The context is that I am working on a Django app (ultimately for
distribution as a plugin) which will require users to write comparisons in
whatever syntax I choose (hence the question about making it pythonic).
The comparisons will reference form fields, and will ultimately be
converted to javascript conditional form display. I suppose an example is
in order:
class MyModel(models.Model):
yes_or_no = models.SomeField...choices are yes or no...
why = models.SomeField...text, but only relevant if yes_or_no == yes...
#here i am inventing some syntax...open to suggestions!!
why.show_if = ('yes_or_no','==','yes')
(hand waving...convert MyModel to ModelForm using
model_form_factory()...gather all "field.show_if" conditions in a
dictionary and attach to ModelForm as MyModelForm.conditions or
something...)
Now in a chunk of javascript in a template, each condition in
MyModelForm.condtions will become a function that listens for a change in
the value of a field, and shows or hides another field in response.
Basically (in pseudo-Javascript/Jquery):
when yes_or_no changes...
if (yes_or_no.value == 'yes'){
$('#div that contains *why* field).show(); }
else {
$('#div that contains *why* field).hide(); }
The goal here is to let the end user specify the conditional display logic
in a straightforward, pythonic way inside the model definition (there may
be an option to specify the conditions on the form class instead, which I
think is more "Djangonic"(??), but for my use case they need to go in the
models). Then my plugin behind the scenes turns that into Javascript in a
template. So you get conditional form display without having to write any
Javascript. Since this will be in the hands of python/django developers, I
am looking for suggestions for the most native, comfortable way to specify
those conditions.

What happens when we close the script two times?
This might be a silly question but i want to clarify this. what happens
when we close a javascript two times.
<script type="text/javascript">
alert("hello");
</script>
</script>
i did this but am not getting any error.its like we closed the script so
there wont be any execution so no error will trigger i believe. will this
create trouble under any situation?
why am asking this is i would like to insert a </script> at the end of a
plugin where user submits their script.

Sencha touch 2 segmented control check which button pressed
Sencha touch 2 segmented control check which button pressed
I have checked this out over the sencha touch examples that the items in
the segmented button can be handled programmatically. The issue that i am
facing currently is how to get the button that is pressed.
I need to store the index of the button that is pressed in my stores for
further references so that when i launch the screen again I am able to
select the buttons over the segmented control based on the selection.
I am handling the toggle event of the segmented button which takes three
arguments: - segmentedbutton - button that is pressed - pressed state.
I have access to the button when the event is generated but I am not able
to find out how to get the index of the button.
Can someone provide some light on this ?
Thanks J

How can I create a duration slider using seconds as raw value in jQuery?
How can I create a duration slider using seconds as raw value in jQuery?
Let's say I have an input that is a text field.
If I typed 3600 then the value would be 60 minutes. I'm tracking the value
of duration based on seconds.
How could I dynamically display a slider that showed seconds if under 1
minute, and over 1 minute it would say 1 minute and x seconds, etc... and
if over a hour it would go 1 hour and 30 minutes and 5 seconds, and so on.
Limited to hours/minutes/seconds.
This slider is just a UI wrapper for seconds as the real value for the input.

Disable input language switching shortcut
Disable input language switching shortcut
I'm not sure what the issue is on my Windows computer but I can't seem to
determine what triggers the input language switcher that I seem to
accidentally press too often.
I have three inputs set up:
English - US Keyboard
French - US Keyboard
French - Canadian Multilingual Standard Keyboard
I know that Windows + Space triggers a menu to choose a language but I
know that is not what I accidentally hit because 1) the menu doesn't show
up and 2) it is rare to press Windows + Space accidentally.
I've heard that Alt + Shift is also another combination and it seems
plausible that that's triggering the behaviour but it isn't because I just
tried to replicate the problem and have tried all combinations of Ctrl,
Shift, and Alt.
The thing is, my input preferences have no keyboard shortcuts configured:

hide element without setting the display to none in jquery
hide element without setting the display to none in jquery
I want to fold a section of the form without setting its display to none.
If i set the display to none, the validation is bypassed that is why I
don't want to set the display to none. I know I can set the visibility to
hidden and visible but this solution is not feasible for rendering the
view as the space for the folded section stays there. This results in a
very odd look of the view with an empty white space with no content on it.
So my question is to hide a section of the html form (without intacting a
placeholder for it) without setting its display to none, so that I could
still perform the validation.

ASCII subset for readable random keys (no O, 0, 1, I or l confusion)?
ASCII subset for readable random keys (no O, 0, 1, I or l confusion)?
Every so often you have to enter a product activation code or similar.
If it's badly designed you end up trying to guess if you're looking at
zeroes or capital Os, or at ones, lowercase Ls or uppercase Is.
Such characters can often only be distinguished by humans by context, i.e.
their use in real words, and so shouldn't be used in random sequences.
Has anyone done any work to determine the subset of letters that most
people can uniquely distinguish in most reasonable fonts irrespective of
context (and assuming reasonable print quality)?
E.g. characters suitable for use in keys sent by plain text email - one
cannot know what font the end user will use to read the email - but it's
likely not too unusual. For printed material one obviously has more
control.
I'll point out before anyone else does that this question is similar to
(some might consider it a duplicate of) "OCR - most "different" or
"recognizable" ASCII characters?"

Salted Password Validation in PHP
Salted Password Validation in PHP
On crackstation.net it is stated:
To Validate a Password
Retrieve the user's salt and hash from the database.
Prepend the salt to the given password and hash it using the same hash
function.
Compare the hash of the given password with the hash from the
database. If they match, the password is correct. Otherwise, the
password is incorrect.
However in the source code listed at the bottom of the page, I can't
figure out how the validate_password function takes into account the salt.
I mean where is the salt prepended to the given password?

I have written proxy as

All the request from http, which contains /req will go to

But the problem is, it is redirected into http://example.com/req

How do I make a button stay pressed in XCode?
How do I make a button stay pressed in XCode?
Okay so I have an app I'm building that is almost complete. I'm just
having one problem, when I press my button it makes a sound and the
button's image changes. However the image on changes when it is being
touched or "highlighted" and I would like the buttons image to remain
changed through the duration of the sound effect then after the sound
effect I would like it to revert back to the original image. Is there
anyway I can set up a UIButton "set time" or something for the
"highlighted" option?
I feel so embarrassed sometimes, because I seem to get tripped up by these
most trivial things, when I handle the core coding exceptionally well and
near finish a full app in a days time, but this is my first app and I'm
still a newbie to XCode. I really appreciate this community's help any
answer that pushes me forward is always appreciated!
I further apologize for my questions formatting I typed this on my iPhone
I hope it's not too awkward or lacking in detail. If anyone needs more
detail just ask!

Complex polynomial identity with norm condition
Complex polynomial identity with norm condition
In this question, the following was shown:
If $R(z)=\dfrac{P(z)}{Q(z)}$, where $P,Q$ are polynomials in a complex
variable $z$, satisfies the condition that $|R(z)|=1$ whenever $|z|=1$,
then the identity $R(z)\overline{R(1/\overline{z})}=1$ holds for all
complex $z$.
The proof given there uses the identity theorem. Since I'm not familiar
with the theorem yet, I would like to find an easier approach.
So I try direct substitution. Writing
$P(z)=a_nz^n+a_{n-1}z^{n-1}+\ldots+a_0$ and
$Q(z)=b_mx^m+b_{m-1}x^{m-1}+\ldots+b_0$, we find that
$$R(z)=\frac{P(z)}{Q(z)}=\frac{a_nz^n+a_{n-1}z^{n-1}+\ldots+a_0}{b_mz^m+b_{m-1}z^{m-1}+\ldots+b_0}$$
and $$\overline{R(1/\overline{z})} =
\frac{\overline{P(1/\overline{z})}}{\overline{Q(1/\overline{z})}} =
\frac{\overline{a_n}+\overline{a_{n-1}}z+\ldots+\overline{a_0}z^n}{\overline{b_m}+\overline{b_{m-1}}z+\ldots+\overline{b_0}z^m}\cdot
z^{m-n}$$
So the identity $R(z)\overline{R(1/\overline{z})}=1$ that we wants to
prove can be turned into
$$z^{m-n}(a_nz^n+a_{n-1}z^{n-1}+\ldots+a_0)(\overline{a_0}z^n + \ldots +
\overline{a_{n-1}}z + \overline{a_n}) =
(b_mz^m+b_{m-1}z^{m-1}+\ldots+b_0)(\overline{b_0}z^m+\ldots+\overline{b_{m-1}}z+\overline{b_m}).$$
where we have the condition that for any $|z|=1$,
$$|a_nz^n+a_{n-1}z^{n-1}+\ldots+a_0| =
|b_mz^m+b_{m-1}z^{m-1}+\ldots+b_0|.$$
How can we proceed from here?
In this question, the following was shown:
If $R(z)=\dfrac{P(z)}{Q(z)}$, where $P,Q$ are polynomials in a complex
variable $z$, satisfies the condition that $|R(z)|=1$ whenever $|z|=1$,
then the identity $R(z)\overline{R(1/\overline{z})}=1$ holds for all
complex $z$.
The proof given there uses the identity theorem. Since I'm not familiar
with the theorem yet, I would like to find an easier approach.
So I try direct substitution. Writing
$P(z)=a_nz^n+a_{n-1}z^{n-1}+\ldots+a_0$ and
$Q(z)=b_mx^m+b_{m-1}x^{m-1}+\ldots+b_0$, we find that
$$R(z)=\frac{P(z)}{Q(z)}=\frac{a_nz^n+a_{n-1}z^{n-1}+\ldots+a_0}{b_mz^m+b_{m-1}z^{m-1}+\ldots+b_0}$$
and $$\overline{R(1/\overline{z})} =
\frac{\overline{P(1/\overline{z})}}{\overline{Q(1/\overline{z})}} =
\frac{\overline{a_n}+\overline{a_{n-1}}z+\ldots+\overline{a_0}z^n}{\overline{b_m}+\overline{b_{m-1}}z+\ldots+\overline{b_0}z^m}\cdot
z^{m-n}$$
So the identity $R(z)\overline{R(1/\overline{z})}=1$ that we wants to
prove can be turned into
$$z^{m-n}(a_nz^n+a_{n-1}z^{n-1}+\ldots+a_0)(\overline{a_0}z^n + \ldots +
\overline{a_{n-1}}z + \overline{a_n}) =
(b_mz^m+b_{m-1}z^{m-1}+\ldots+b_0)(\overline{b_0}z^m+\ldots+\overline{b_{m-1}}z+\overline{b_m}).$$
where we have the condition that for any $|z|=1$,
$$|a_nz^n+a_{n-1}z^{n-1}+\ldots+a_0| =
|b_mz^m+b_{m-1}z^{m-1}+\ldots+b_0|.$$
How can we proceed from here?

Just this code nothing else (not saving to db I'm only running above i.e.
create the objects). It takes 15 mins for 5000 messages objects to be
created in the query. Is this right? Why is Django so slow?
This is the model it creates, again I'm not saving here. I think there ahs
to be an issue in the model when an object is created, that or Django is
just too slow for my needs.

com.apple.finder AppleShowAllFiles updates automatically [duplicate]
com.apple.finder AppleShowAllFiles updates automatically [duplicate]
This question already has an answer here:
AppleShowAllFiles does not show hidden files 5 answers
I have been trying to write a shell script which could toggle visibility
of hidden files
CURRENT_STATUS=`defaults read com.apple.Finder AppleShowAllFiles`
NEW_STATUS="YES"
if [ "$CURRENT_STATUS" = "YES" ]; then
NEW_STATUS="NO"
fi
defaults write com.apple.Finder AppleShowAllFiles $NEW_STATUS
sudo killall Finder
Something really weird happens when I run this script. After I have
updated the Status using the write command sometimes (not always) the
value reverts back. So say for example if I set the value as YES after
sometime on restarting the Finder app the value will turn back to NO. Can
someone help in figuring out why this happens?
Update: I found the solution here: AppleShowAllFiles does not show hidden

Git .gitignore not working
Git .gitignore not working
I am having some problems with my GIT repo ... I have a few folders added
in my ".gitignore" file. They contain over 100k files. Mainly images, tmp
and cache stuff. What I need is to be able to commit changes to my code
with out commiting what happens in those folders. I thought adding them
into the ".gitignore" would do the trick but for some reason it's not
working at all... I havant been abble to commit anything to the repo in
days because every time I try the push command it trys sending 100k files
then it frozes and times out.
root@serveur [/home/***/***]# git push origin master
Password:
Counting objects: 110300, done.
How can I force GIT to reindex the tree while taking in consideration the
ignored folders so I can finaly commit all the changes I made to the code.
A merge is planed today !

Javascript: function associated with create element not working
Javascript: function associated with create element not working
I have a select element from createElement which I want to have replaced
with a text input element with an onchange event, but my code for it
doesn't work. Here's the code (the select element itself is appended to
other div elements that are also created):
<script>
var countess = 0;
function adadd(){
var child = document.getElementById("geneadd");
if (child.value === "add")
{countess++;
if (countess < 2)
{
var divi=document.createElement("div");
divi.name = "diviena";
divi.id = "divienid";
divi.class = "table";
var elemdivi = document.getElementById("fieldsetid");
elemdivi.appendChild(divi);
}
var divii=document.createElement("div");
divii.name = "divienaa" + countess;
divii.id = "divienidd" + countess;

PHP Chaining: how to get data from a mysql table?
PHP Chaining: how to get data from a mysql table?
I am trying to implement PHP chaining method in my web development
project. But I seem can't get it right.
class foo extends base{
public $query = null;
public $item = array();
public function __construct($connection){
parent::__construct($connection);
}
public function select($query){
$this->query = $query;
return $this;
}
public function where($query){
$this->query = $query;
return $this;
}
public function __toString()
{
$this->item = $this->connection->fetch_assoc($this->query);
return var_export($this->item, true);
}
}
$connection = new db($dsn = 'mysql:host=localhost;dbname=xxx',$username =
'xxx',$password = 'xxx');
$foo = new foo($connection);
$select = $foo->select("SELECT * FROM page")->where("page_id = 10 ");
print_r($select->item);
the result I get,
Array
(
)
But I should get a row of data. Just like I normally do it in this way,
class boo extends base{
...
public function select() {
$sql = "
SELECT *
FROM page
WHERE page_id = ?
";
$item = $connection->fetch_assoc($sql,array(1));
return $item;
}
}
What have I missed in my chaining method?

Recipe from Python Cookbook
Recipe from Python Cookbook
I'm trying to implement a recipe from O'Reilly's Python Cookbook (2nd ed.)

someone could help me figure out why.
The recipe is "5.14: Enhancing the Dictionary Type with Ratings
Functionality." I've got most of the code working, but I get an error when
trying to change the 'ranking' of a key. I've left in all the comments as
the author's so as anyone trying to help will have a good idea about what
the "unders" and "dunders" are for. Especially the "_rating" aspect, which
I believe is somehow causing the error.

trying to change the 'ranking' of a key. I've left in all the comments as
the author's so as anyone trying to help will have a good idea about what
the "unders" and "dunders" are for. Especially the "_rating" aspect, which
I believe is somehow causing the error.

wordpress: remove duplicate phrases in a foreach loop
wordpress: remove duplicate phrases in a foreach loop
I have the following problem:
In my wordpres 3.6 I have for posts a custom field called: "topics". The
field is automaticlly filled with phrases from another website by RSS, and
it adds multiple criteria. It is filled in like this:
"Cars,Bikes,Stuff,Gadget"
When I query wordpress with get_posts I get in my foreach loop this:
Cars,Bikes,Stuff,Gadget
Cars,Bikes
Bikes,Stuff
Gadget
I put this into a string and replace some stuff:
$topic_filter = get_posts(
array(
'numberposts' => -1,
'post_status' => 'private',
)
);
$search_topic = array(' ', '-&-', '-|-', '-/-', '---');
$replace_topic = array("-", "-", "-", "-", "-", "");
foreach ($topic_filter as $post_topic) {
$str = str_replace($search_topic, $replace_topic,
get_post_meta($post_topic->ID, 'topic', true));
echo $str;
}
final echo putput is then:
Cars,Bikes,Stuff,Gadget,Cars,Bikes,Bikes,Stuff,Gadget
So far so good. But how to remove the duplicates now?
I tried implode / explode, but it doesn't do anything, because the items
are in a foreach loop I think, and it only apply inside for each post.
But I need the foreach loop, because in the end the goal is to get this
cleaned string as a list in an html output something like this:
<input
type="button"
value="Cars"
class="filter-button"
data-control-type="button-filter"
data-control-action="filter"
data-control-name="Cars-btn"
data-path=".Cars"
/>
<input
type="button"
value="Bikes"
class="filter-button"
data-control-type="button-filter"
data-control-action="filter"
data-control-name="Bikes-btn"
data-path=".Bikes"
/>
<input
type="button"
value="Gadget"
class="filter-button"
data-control-type="button-filter"
data-control-action="filter"
data-control-name="Gadget-btn"
data-path=".Gadget"
/>
seems pretty complicated to me :-(
any ideas? I would be really happy for your help!
Thanks!

Netbeans. Code auto-formatting - Swing layouts section
Netbeans. Code auto-formatting - Swing layouts section
Do you know if is it possible to turn off the auto-code-formatting
(ALT+SHIFT+F) for some particular code fragments in Netbeans? I found some
similar questions, so I see I'm not alone:
Post on netbeans-org
NetBeans, Turn off **ANY** auto indentation / auto formatting
Auto code formatting is excellent and I use it very often, but there are
some cases in which I would like to turn it off. The most frequent case
is, when I have code with Swing's GroupLayout. Example:
inputPanelLayout.setHorizontalGroup(inputPanelLayout.createParallelGroup(javax.swing.GroupLayout.Alignment.LEADING)
.addGroup(inputPanelLayout.createSequentialGroup()
.addGroup(inputPanelLayout.createParallelGroup(javax.swing.GroupLayout.Alignment.LEADING)
.addComponent(lbl1, labelWidth1, labelWidth1, 100)
.addComponent(lbl2, labelWidth1, labelWidth1, 100)
.addComponent(lbl3, labelWidth1, labelWidth1, 100)
.addComponent(lbl4, labelWidth1, labelWidth1, 100)
.addComponent(lbl5, labelWidth1, labelWidth1, 100)
.addComponent(lbl6, labelWidth1, labelWidth1, 100)
.addComponent(lbl6, labelWidth1, labelWidth1, 100))
.addGap(10, 10, 10)
.addGroup(inputPanelLayout.createParallelGroup(javax.swing.GroupLayout.Alignment.LEADING)
.addGroup(inputPanelLayout.createSequentialGroup()
.addComponent(getTxtSomeField(), 50, 100, 150)
.addGap(EDIT_BTN_GAP)
.addComponent(lbl12))
.addComponent(txt5, 50, 122, 150)
.addComponent(txt3, 50, 122, 150)
.addComponent(txt6, 50, 122, 150)
.addComponent(txt7, 50, 122, 150)
.addComponent(txt3, 50, 122, 150)
.addComponent(txt4, 50, 122, 150))
.addGap(16, 16, 16) ... etc
Everything is aligned to left and it's a horror when I have to add
something inside existing layout when it has, for instance, 50 components.
Question: Have you ever came across any solution, which enables to turn
auto-formatting for some particular code fragment?

When hovering over link, website randomly changes the hover background size
When hovering over link, website randomly changes the hover background size
While working on my website, I have decided to incorporate PHP just to
play around with. I figure I'm paying for it in hosting (sort of), so
might as well use it. The problem I am having is when I hover over a link
in the nav bar I have made, the hover "decoration" that I am using changes
the hover background height. Problem is, it does it on every page BUT not
all the time. Seems random. For some reason it seems to be doing it more
on my about page but I have seen it do it on others. I haven't made any
changes to the others to make them stop nor any changes to the about to
make it start more.

At the top of the about page I included the Facebook code that I am using
so that you all know it is there in case you all might think that is it. I
have poured over the code a lot but I cant see an error. The fact that it
is the same php file used on all pages and every page has had issue at
least once but not always confuses me.
I have tested on Firefox and IE 10

Clientaccesspolicy.xml File Garbled When Accessed from Silverlight App
Clientaccesspolicy.xml File Garbled When Accessed from Silverlight App
I'm stumped. I have created a WCF service for serving up Telerik reports
to a Silverlight 4 application (actually a VS LightSwitch 2010 app). The
service is on a different subdomain (let's call it reports.mydomain.com)
from the Silverlight application (say app.mydomain.com) so I have placed a
clientaccesspolicy.xml file in the root of the IIS7.5-hosted service site
that looks like this:
<?xml version="1.0" encoding="utf-8" ?>
<access-policy>
<cross-domain-access>
<policy>
<allow-from http-request-headers="*" http-methods="*">
<domain uri="http://app.mydomain.com">
</domain>
</allow-from>
<grant-to>
<resource path="/">
</resource>
</grant-to>
</policy>
</cross-domain-access>
</access-policy>
When I browse to the clientaccesspolicy.xml file in Firefox, I see the XML
just fine. However, when my Telerik Silverlight report viewer control
attempts to access it (I'm verifying this with FireBug), the response it
gets is garbled.
Here's the Firebug output:
And here:
I tried turning off compression in IIS for the WCF site but this had no
effect. Still garbled.
Finally, here's the XML file when accessed in the browser:
Any ideas?

Column-Width and Image Wrapping in Firefox
Column-Width and Image Wrapping in Firefox
Using the CSS3 column-width property in Firefox seems to not work as
expected. When an image that is taller than it's container exists, the
image does not wrap onto a new column as expected:
Example in JSFiddle
<div id="container">
<img src="http://placehold.it/300x600" alt="" />
</div>
and
#container {
border: 1px solid #000;
width: 1200px;
height: 300px;
-moz-column-width: 300px;
-webkit-column-width: 300px;
}
One would expect two columns with the top half on the left followed by the
bottom half of the image. This works as expected on Chrome, however with
Firefox, it seems to simply overflow. Is there an additional CSS style
that needs to be applied in this case, or is this something that is
broken/not implemented in Firefox?

gcc c error: expected ')' before numeric constant
gcc c error: expected ')' before numeric constant
Hi I have been trying to port LWIP to a new arm device. When compiling the
code i get the error message:
"lwip/lwip-1.4.0/src/include/lwip/memp_std.h:35:23: error: expected ')'
before numeric constant"
When I go to this file this and below this several similar macros is what
I find on that line:
LWIP_MEMPOOL(RAW_PCB, MEMP_NUM_RAW_PCB, sizeof(struct raw_pcb),
"RAW_PCB")
If I remove the need for this macro with a define to deactivate the RAW
functionality the erorr.
The define it seems to want to put a ')' in front of is defined as this:
#define MEMP_NUM_RAW_PCB 1
The RAW_PCB is not defined but is "combined with MEMP_" to create an
element in an enum.
I have tried to complie the whole ting with the -E option to get human
redable object files and see if i can find any open '(' around the areas
where MEMP_RAW_PCB apears and the substitution of MEMP_NUM_RAW_PCB to 1
but I have not found any by manual inspection yet.
Are there any suggestions on what can be going on here or what more I can
do or look for to find the cause of the error?
I should maybe add that so far I don't call on any of the LWIP code from
main() or any of the functions used in main().

Use CreateThread with a lambda
Just experimenting, but I was wondering if it's possible to make this code
work:
void main() {
int number = 5;
DWORD(*dontThreadOnMe)(PVOID) = [](PVOID data) {
int value = *(int*) data;
cout << value << endl;
cout << "This callback executed successsfully" << endl;
};
CreateThread(NULL, NULL, dontThreadOnMe, &number, NULL, NULL);
cin.get();
}
I have this nagging suspicion that because the standard signature for a
LPTHREAD_START_ROUTINE callback is DWORD WINAPI Callback(PVOID) I won't be
able to get this to compile without the added (but grammatically illegal)
WINAPI tag. Speaking of which, what exactly are the WINAPI and CALLBACK
(for say WndProc) attributes? I've never really understood why in certain
circumstances you could have multiple attributes on a function.

Switch scope between the browser and dev tools (normal pane and mini console) with keyboard
Switch scope between the browser and dev tools (normal pane and mini
console) with keyboard
In Chrome, when using the dev tools, I sometimes want to switch between
the actual bowser window, and the dev tools window. What keyboard shortcut
exists if at all? Currently I have to click on on window to switch scope.

How do i use Apache for Upload and Nginx for Secure Download
How do i use Apache for Upload and Nginx for Secure Download
I have a website, for file sharing which is in perl, now there is file
index.dl which is used for download request. In apache it creates a very
high load, the load goes almost at 100.
Now i can not use nginx proxy.
I want to set apache to handle all the uploads, and nginx to handle the
download requests.
I have checked there is a module "http-secure-link-module" so i have
installed that as well.
Now our site generates the file download link like
xyz.com/d/$hash/filename.xyz
now this is the code that generates the link
sub genDirectLink
{
my ($file,$mode,$mins,$fname)=@_;
require HCE_MD5;
my $hce = HCE_MD5->new($c->{dl_key},"mysecret");
my $usr_id = $ses->getUser ? $ses->getUserId : 0;
my $dx =
sprintf("%d",($file->{file_real_id}||$file->{file_id})/$c->{files_per_folder});
my $hash = &encode32( $hce->hce_block_encrypt(pack("SLLSA12ASC4L",
$file->{srv_id},
$file->{file_id},
$usr_id,
$dx,
$file->{file_real},
$mode||'f',
$c->{down_speed},
split(/\./,$ses->getIP),
time+60*$mins)) );
#$file->{file_name}=~s/%/%25/g;
#$file->{srv_htdocs_url}=~s/\/files//;
my ($url) = $file->{srv_htdocs_url}=~/(http:\/\/.+?)\//i;
$fname||=$file->{file_name};
return "$url:182/d/$hash/$fname";
}
sub encode32
{
$_=shift;
my($l,$e);
$_=unpack('B*',$_);
s/(.....)/000$1/g;
$l=length;
if($l & 7)
{
$e=substr($_,$l & ~7);
$_=substr($_,0,$l & ~7);
$_.="000$e" . '0' x (5-length $e);
}
$_=pack('B*', $_);
tr|\0-\37|A-Z2-7|;
lc($_);
}
and i have setup my nginx config as
server {
listen 182;
server_name myhost.com www.myhost.com;
location / {
root /home/user/domains/hostname.com/public_html/files;
}
location /d/ {
secure_link_secret mysecret;
if ($secure_link = "") {
return 403;
}
rewrite ^ /files/$secure_link;
}
location /files/ {
internal;
}
So now the problem is, when i tried to visit any link, it gives 404 error.

How to automatically create a cart for a customer in prestashop?
How to automatically create a cart for a customer in prestashop?
I would like to create automatically a cart for a customer with a product.
Then the customer can login on the site and validate the cart.
I saw how to create a cart in my module but i don't understand how to
affect the cart to a customer?

Python multiprocessing exiting cleanly
Python multiprocessing exiting cleanly
I've got a daemon that runs a number of child processes intended to
maintain a telnet connection to collect data from a bunch of weather
stations. I've set it up so that these child processes read from that
telnet connection forever, passing the weather readings back to the parent
process via a multiprocessing.Queue. I can't seem to get these child
processes to exit cleanly when I stop the daemon with ./test.py stop. Is
there an easy way to close the child processes on exit? A quick google
mentioned someone using multiprocessing.Event, what's the best way to set
this event on exit to ensure the processes exit? Here's our current code:
from daemon import runner
from multiprocessing import Process, Queue
import telnetlib
from django.utils.encoding import force_text
from observations.weather.models import WeatherStation
import os
os.environ['DJANGO_SETTINGS_MODULE'] = 'settings'

print "Started process to get data for", name
client = telnetlib.Telnet(ip_address, port)
while True:
response = client.read_until('\r\n'.encode('utf8'))
queue.put((name, force_text(response)))
client.close()

def __init__(self):
self.stdin_path = '/dev/null'

for station in WeatherStation.objects.filter(active=True):
p = Process(target=read_weather_data,
args=(station.name, station.ip_address, station.port,

p.start()
while True:
name, data = queue.get()
