Major differences between mod_fastcgi and mod_proxy_fcgi
Major differences between mod_fastcgi and mod_proxy_fcgi
I noticed there are a couple of modules for Apache that provide FastCGI
support. The two most popular seem to be mod_fastcgi and mod_proxy_fcgi.
There seem to be other ones as well.
My questions are:
Which of these module are the most popular?
Which of them are considered obsolete.
The reason I am asking is that I'm writing FastCGI support for a certain
scripting language and I wonder which setups I should primarily test with.
Granted, FastCGI is a standard so, in theory everything should be
portable. On the other hand, there seem to be certain differences
concerning application server start-up, etc. I would also like to write
some "how-to's" once I'm finished, so I would like to know which options
to cover primarily.
Hope this is not an open-ended question.

want to do is delete a particular row using a check box which user
selects. Can anyone tell me how can i detect which check box user has

2 calculations with one populate button
2 calculations with one populate button
I have a simple worksheet that auto populates hours based on key values.
This all works fine. The problem I have now is that I need to add some
form of a contingency column which is a percentage figure of the total
hours used up to this column. Add the contingency figures to the sheet and
carry on with the populate.
Is there anyway i can do the first populate up to the contingency column.
Stop. Get the current value (for total hours) then do some calculations
and then carry on with the auto populate?
I don't really have any code I can share, but any pointers in the right
direction would be extremely useful.
Thankyou for your time.

Why is Internet traffic being blocked for .NET programs ONLY?
Why is Internet traffic being blocked for .NET programs ONLY?
We have a POS-based application in Windows Forms written in VB.NET, which
we're rolling out to franchise stores - 70, so far.
The application replicates data by means of a connection to a head office
server: all communication is by means of Web Services (upload & download).
All is working really well, except - you knew it was coming - on literally
a handful of stores we cannot connect to the web services, although we
know that the Internet service is good!
Here's a bullet-point summary of the situation:
in this handful of stores, ALL .NET (only) internet traffic fails on this
POS computer.
primarily this traffic is using port 80 to connect to web services, using
SOAP (standard)
BUT they can successfully use a browser in the POS to see web pages; also,
a test program I created in Clarion (straight Win 32) also connects to the
web service ok.
In addition, an associated data conversion app (again in VB.NET) also
fails when trying to connect to MS SQL at HQ (and only for this handful of
stores). Note: this uses a standard ADO connection, thus a completely
different protocol to the above.
So it's just all .NET Internet that fails... different apps, different
protocol. The error message in all cases is "The operation has timed out"
Note: timeout is set to 15 seconds - ample time for simple web service,
esp. as the initial method is just a time-check.
Take a POS that's failing to connect and move to a different site: all good
Take a POS that's failing to connect and change the router: all good
But the routers in failing stores are not all the same
It looks as if the .NET setup on the POS pc is somehow being 'blocked'.
Too weird - what am I missing here?
Grateful for pointers... I'm stumped! Steve.

How to load a column generated by awk into a python list
How to load a column generated by awk into a python list
With awk it is very easy to extract a column of data in the bash terminal
using.
awk '{print $1}'
I am doing this inside a python script where i use a bash sequence to
extract the data i'm interested in
os.system(" qstat | awk '{print $1}' ")
If i call this in a certain context I get a column of numbers. I would
like to load all of those numbers into a python list. Can this be done
easily?

Turn off vibration inside my app
Turn off vibration inside my app
I'm developing an app and need to completely turn off vibration alerts
when my app is running. For example if an call comes in while my app is
open I don't want to have the vibration alert, the same with emails and
anyother notification.
So I've been googling around for a while and found this:
AudioManager amanager=(AudioManager)getSystemService(Context.AUDIO_SERVICE);
amanager.setVibrateSetting(AudioManager.VIBRATE_TYPE_RINGER,AudioManager.VIBRATE_SETTING_OFF);
The problem is that this method is deprecated. And I can't find an other
way of doing this.
The minSdkVersion = 9 and targetSdkVersion = 17.
Any idea?
Thanks!!

SAS / SAS2..... compatible?
SAS / SAS2..... compatible?
Is it theoretically possible to mix a SAS2 controller with a SAS expander?
We just happen to have this scenario - the expander (which works fine with
an older SAS adaptec controller) is not found and Adaptec (which handle
the new 71605Q raid controller) insists on telling me this is because the
expander is a SA expander and not a SAS2 expander.
We are in the proces of upgrading our infrastructure - so this test case
is not by any means a deaster - but we can not remove certain SAS elements
YET (mostly because not everything is available as SAS2 yet).
I was using my google-fu trying to find an answer but I can not find any
auhorititative document / description about whether this should work in
general.

How to create a self configuring mobile app with Javascript
How to create a self configuring mobile app with Javascript
I am looking at using Jquery mobile and Phonegap to create a mobile app.
If I know the structure of my app beforehand I can do this. However, I
want to be able to have the ability for the app to connect to a server and
add/remove pages based on the configuration for the app stored on the
server.
Once the app has reconfigured itself it should work completely offline.
Is there some way to manage this in Javascript land or do I need to manage
the reconfiguration with native code?

jQuery slider opacity error only on Google Chrome
jQuery slider opacity error only on Google Chrome
I have a custom built slider on a Magento site. It's responsive and have
custom touch behaviour on it. The behaviour should be the following:
Three images slider, the middle one should have opacity 1.0, the rest just
0.15
On smaller resolutions, only show 2 images. The one on the right should
have 1.0 the left image should have 0.15 opacity
On mobile, show 1 image. The current shown image should have 1.0 opacity.
I made it work with CSS/jQuery mix.
HTML
<ul class="more-views">
<li><a href="someURL"><img src=..... /></li>
<li class="active"><a href="someURL"><img src=..... /></li>
<li><a href="someURL"><img src=..... /></li>
<li><a href="someURL"><img src=..... /></li>
<li><a href="someURL"><img src=..... /></li>
</ul>
CSS .more-views ul li { opacity: .15; } .more-views ul li.active {
opacity: 1.0; }
JAVASCRIPT is long, you might want to inspect element. But the idea is the
following. When you click NEXT arrow, the first element of the list is
cloned, appended to the back of the and destroyed from the first position.
Later on the active class is removed and added to the second <li> in the
list. Something like this
<ul>
<li class="elem1"></li>
<li class="elem2 active"></li>
<li class="elem3"></li>
<li class="elem4"></li>
</ul>
STEP 1
<ul>
<li class="elem1"></li>
<li class="elem2 active"></li>
<li class="elem3"></li>
<li class="elem4"></li>
<li class="elem1"></li>
</ul>
STEP 2
<ul>
<li class="elem2 active"></li>
<li class="elem3"></li>
<li class="elem4"></li>
<li class="elem1"></li>
</ul>
STEP 3
<ul>
<li class="elem2"></li>
<li class="elem3 active"></li>
<li class="elem4"></li>
<li class="elem1"></li>
</ul>
Current small issue is the following: 1. If you click the right arrow
(next arrow) one time, the first element in the list keeps the opacity as
1.0 (only on Chrome). 2. If you inspect the element is says it has an
opacity of 0.15 3. If you resize the browser you'll see that the opacity
is set to .15 again 4. If you enable/disable the opacity in Firebug it
works like it should. 5. If you click 2 times on the next arrow the
opacity error disappears.

Below is a class I have for a 2 class project. Basically I want to parse
the title of the wiki page, and save it to the string title or something I
can call from another class using something like
retrieveTitle.setText(WikiSearcherExtension.title); In eclipse its telling
me the local variable title isnt being used at all to store the node
information.
It wouldnt let me paste the xml as a block of code so here is the url I
have been using
http://en.wikipedia.org/w/api.php?action=query&prop=revisions&format=xml&rvprop=timestamp&rvlimit=1&rvtoken=rollback&titles=test&redirects=
public class WikiParserTrials {
private String wikiInformation;
private String wikiUrl;
String title;
public void urlRefactor(String url) throws IOException {
String wikiPageName = url.replaceAll(" ", "_");
wikiUrl =
"http://en.wikipedia.org/w/api.php?action=query&prop=revisions&format=xml&rvprop=timestamp&rvlimit=1&rvtoken=rollback&titles=test&redirects=";
setUrlInformation();
}
private void setUrlInformation() throws IOException {
URL url = new URL(wikiUrl);
URLConnection connection = url.openConnection();
BufferedReader reader = new BufferedReader(new
InputStreamReader(connection.getInputStream()));
wikiInformation = "";
for (String line = reader.readLine(); line != null; line =
reader.readLine()) {
wikiInformation += line;
}
}
public class ReadAndPrintXMLFile {
public void main(String argv[]) {
try {
DocumentBuilderFactory dbf =
DocumentBuilderFactory.newInstance();
DocumentBuilder db = dbf.newDocumentBuilder();
InputSource is = new InputSource();
is.setCharacterStream(new StringReader(wikiInformation));
Document doc = db.parse(is);
NodeList nodes = doc.getElementsByTagName("normalized");
for (int i = 0; i < nodes.getLength(); i++) {
Element element = (Element) nodes.item(i);
NodeList name = element.getElementsByTagName("to");
Element line = (Element) name.item(0);
String title = (getCharacterDataFromElement(line));

PayPal PDT auth parameter
PayPal PDT auth parameter
I'm setting up PayPal PDT and IPN for a subscription/recurring payment
button.
I'm using PayPal's documentation to explain the returned parameters, but
one of them is not mentioned.
The auth parameter is ~87 characters long and looks like this:
AHJkv4ukrM7kwTPe7tt9Q.TPnHnUeQWJyNz4WQsMOKhYrZoaPknmceOp-G.voqTJ2V0ODJYC2u1maUdxl9-iBkg
What is this parameter? and how can I use it?

What would be a safe and practical way to copy a string as defined by this prompt in C?
What would be a safe and practical way to copy a string as defined by this
prompt in C?
The purpose of this function is to copy a string into a "buffer" -
essentially another string. However, the problem seems overly complicated
than what would be practical.
"Copies at most n-1 characters of string in into the buffer pointed to by
out. If n is reached, returns -2. Otherwise, returns -1 for malformed
input and 0 upon successful completion."
This is what I have:
#include <stdio.h>
#include <assert.h>
int copyStringN(register char *in, register char *out, register int n){
//Declarations
int i; //Dummy index
if(!in || !out) return -1;
for(i=0; i<n; i++){
*out++ = *in++;
}
*out = '\0';
return 0;
}
int main(void){
//Declarations
char in[] = "I'm not trying to inject malicious code...\\x29A.";
const int N = sizeof(in);
char out[N];
int err;
//Main execution
printf("\nThis function will copy at most n-1 characters of string
into\nthe buffer pointed to by out.\n\n");
err = copyStringN(in, out, N);
assert(!err);
printf("%s\n", out);
printf("\nPlease press enter to exit...");
getchar();
return 0;
}
This general form was suggested, but it seems overly convoluted than what
needs to be done. Why would n ever be reached? The execution should stop
before n. Furthermore, wouldn't N = sizeof(in) match the length of the
original string?
Personally, I would rather use a function closer to
int copyStringN(register char *in, register char *out)
{
if((!in || !out) && (sizeof(in)<=sizeof(out))) return -1;
else{
while(*t++ = *from++);
return 0;
}
}
int main(void){
//Declarations
char in[] = "I'm not trying to inject malicious code...\\x29A.";
const int N = sizeof(in);
char out[N];
int err;
..
..
..
I believe it would have the same effect with less statements. Let me make
this more of a question, how could I write a function that copies a string
into another array with the protection defined in the prompt? Also, are
the two programs that I presented somehow vulnerable in a way I don't
recognize?
Constructive input is appreciated.

PHP - Force integer conversion to float with three decimals
PHP - Force integer conversion to float with three decimals
I am trying to convert a big array of numbers to a specific format which
is +/-NNN.NNN. So, if I have these numbers:
$numbers1 = array(-1.23, 0.3222, 10, 5.54);
I want their final format to be
$numbers2 = array(-001.023, +000.322, +010.000, +005.054);
I am trying to do it like this:
foreach ($numbers1 as $n) {
$fnum = abs(number_format((float)$n, 3, '.', ''));
if ($fnum>0 && $fnum<10) {
$fnum = '00'.$fnum;
} else if ($fnum >= 10 && $fnum<100) {
$fnum = '0'.$fnum;
}
if ($n>0) $fnum = '+'.$fnum;
if ($n<0) $fnum = '-'.$fnum;
if ($n == 0) $fnum = '+000.000';
$numbers2[] = $fnum;
}
This is wrong and I just don't know what to use in order to achieve it.

Haskell differenct in showing Data.Text
Haskell differenct in showing Data.Text
Consider the next code in GHCi:

*> let r = R $ pack "¶"

¶
*> s r
"\182"
Why does it shows the paragraph sign without the quotes and when showing R
datatype. And showing like [Char] (actually, :t s r is Text) when showing
s r?

matplotlib.pyplot contourf function introduces holes or gaps when plotting regular data
matplotlib.pyplot contourf function introduces holes or gaps when plotting
regular data
I am trying to plot a 3D dataset using the contourf function in
matplotlib.pyplot. All of this is being run inside an iPython notebook. A
surface plot of the data looks fine, but the contourf plot has a big hole
in it.
A simplified version of the code I am using is:
import numpy as np # import modules
import scipy.io as spio
import matplotlib.pyplot as plt
from mpl_toolkits.mplot3d import Axes3D
fig = plt.figure(figsize=(12,5))
zMin = 1.2
data = spio.loadmat('./OD_SurfMatFiles/surf_k2_c3.mat')
X = data['xVal']
Y = data['yVal']
Z = data['zVal']
plotX, plotY = numpy.meshgrid(X, Y)
ax = fig.add_subplot(1,2,1, projection='3d')
colourLevels = [0.0, 0.4, 0.8, 1.2, 1.6, 2.0, 2.4];
cset = ax.contourf(plotX, plotY, Z, colourLevels, zdir='z',offset=zMin,
cmap=cm.autumn)
CB = plt.colorbar(cset, shrink=0.5, extend='both')

how totalorder partitioner works in hadoop?
how totalorder partitioner works in hadoop?
i am new to this concept of totalorder partitioner in hadoop
i have some questions on this concept
1) how the sorting happens internally using totalorder partitioner?
2)why are we using an input sampler in this concept?
3)how can i know the number of reducers to set?
4) why are we using partitioner here?
5)what is a partition file?
i had above doubts while going through that concept.can anyone explain me
these concepts?
Thanks in Advance

Alphabetical selection sort of a 2D array
Alphabetical selection sort of a 2D array
My assignment asks me to store inputted data in a 2D array and use a
selection sort to sort the crimes in alphabetical order. How can I alter
the following selection sort:
//selection sort
for(i = 0; i < criminal.length; i++){
smallest = i;
for(j = i; j < criminal.length; j++){
//compare smallest to current position
if(criminal[j] < criminal[smallest]){
smallest = j;
}
//swap smallest with position in the array
temp = criminal[i];
criminal[i] = criminal[smallest];
age[smallest] = temp;
}
}
//output
for(i = 0; i < criminal.length; i++){
System.out.println(criminal[i]);
}
So that it can accommodate a 2D array that looks like this:
//loop to request to fill array
for (i = 0; i < criminals.length ; i++) {
System.out.print("Enter first and last name of criminal: ");
criminals[i][0] = br.readLine(); //Criminal Name
System.out.print("Enter crime committed: ");
criminals[i][1] = br.readLine(); //Criminal Crime
System.out.print("Enter year of conviction: ");
criminals[i][2] = br.readLine(); //Year of conviction
}
That's it. Any help would be great! I really need to finish this ASAP.
Thanks in advance. :)

How would I create a long running process in C#?
How would I create a long running process in C#?
This may seem very elementary, but I don't really have any experience in
this realm - all my experience has been on the web side of things.
I need to create a process of some sort that will repeatedly query an API
(around 5 times a second), get the results from the API (in JSON format),
and then my process will do what it needs to do with the results (in my
case, insert them into a SQL database). These details don't really matter
to the scope of the question I have, I just want to give you an idea on
what I'm trying to achieve in case someone wants to recommend a better way
of doing it.
My first thought was to create a console app that basically never quits
(unless I specifically tell it to). Is a console app the way to go for
this? The idea is I'll have a VM set up which will host my solution,
including this "process" I create. I'm not all too familiar with Windows
Services, or Windows Tasks, but I probably need to write some custom code
so therefore I imagine I can't use the Windows Task Scheduler, am I right?

Preventing Pages theme from being imposed on each aspx page directive during compilation
Preventing Pages theme from being imposed on each aspx page directive
during compilation
in my web.config i use the following pages declaration
<pages maintainScrollPositionOnPostBack="true" Theme="Theme1">
with the intention of being able to use different themes on a web
application to customize the way it displays for a few different
clients(some of which want their own branding on the web application's
pages)
if i leave out the theme directive in my development code, it doesn't
display properly when debugging, so i want to have the Theme defined in
the web.config... however when it is defined as above and i go to publish
my solution every .aspx page declaration goes from this:
<%@ Page Language="VB" CodeFile="MRSHome.aspx.vb"%>
to this:
<%@ page language="VB" inherits="App_Web_peiwi24o" theme="Theme1"
maintainScrollPositionOnPostBack="true" %>
and page level theme declarations override the ones set in the web.config
file, i need that to remain the case since some pages programmatically
switch to a print friendly theme when the user needs it.
How do i prevent the web.configs pages settings from being appended to
each page's page declaration during compilation?

Design best practice: How to display in JSP an object with partial collection needed, for application that uses Hibernate?
Design best practice: How to display in JSP an object with partial
collection needed, for application that uses Hibernate?
I have an object Master that has a collection of Student objects. I have a
list of Master objects and I would want to display in the JSP the Master
fields and only the Students that have a score greater than some constant.
I cannot partially load a collection to have only the desired students
because Hibernate does not function like this. I can only filter it in
another collection but I won't have the collection bound to the Master
object for displaying this in the JSP.
My solution for displaying this in the JSP is to use an Wrapper object and
create instances after loading the data from the DB. After that I can use
the object to display it in the JSP:
Class WrapperMaster{
Master master;
Set<Student> filteredStudents;
}
Questions:
Won't this be just a silly and maybe reduntant thing to do?
I will have encapsulated persistent objects contained in another object
(that is unpersistent). Is this a best practice?
An alternative would be to not use the Wrapper object, but filter manually
the collection of students from the Master object in the JSP. I use
Struts2 so I would have to use many <s:if> tags.

should they be used
I am learning javascript. I am confused between the following two
notations where the newly created objects inherit the properties. How are
they different and when should i use them?
Code 1:
var Vehicle = function Vehicle() {
this.wheel=2
}
var vehicle = new Vehicle();
alert(vehicle.wheel);
Code 2:
var Vehicle = function Vehicle() {
}
Vehicle.prototype.wheel = 4;
var vehicle = new Vehicle();
alert(vehicle.wheel);
When is the keyword prototype used?

Java Math.min() Error on Integer.Max_Value
Java Math.min() Error on Integer.Max_Value
This code, which should return the smaller of the two numbers, returns a
negative number similar to the greater number:
Math.min(15, 21474836477) --> returns -2147483642
I suspected this had something to do with the range of int's, so I changed
the values to long and the program worked fine.
I don't quite understand the seemingly random number it returns- why is it
-2147483643 and not the actual number I put in, -21474836477? Is the
difference caused by the amount it overflowed, or is it influenced by the
other parameter of Math.min in some way?

Mysql datatype SET with rails
Mysql datatype SET with rails
So for some reason, our database guy decided to use the mysql datatype
set. I'm trying to make it work with rails. Here is our column:
actions => set('spoke_to','left_voicemail','emailed')
To make it work I have the following code which i'm sure could be far better:
def actions=(type)
write_attribute(:actions, pack(type))
end
def actions
read_attribute(:actions).split(",") unless
read_attribute(:actions).nil?
end
private
def pack(type)
acs = self.actions
if acs.present? && acs.include?(type)
acs.delete(type)
delete_actions(acs)
else
write_actions(acs, type)
end
end
def delete_actions(acs)
if acs.empty?
write_attribute(:actions, nil)
else
write_attribute(:actions, acs)
end
end
def write_actions(acs, type)

if acs.present?
write_attribute(:actions, acs.push(type).join(","))
else
write_attribute(:actions, type)
end
end
However, setting the action(s) works just like fine, but when I try to
unset one I have the following weird query being generated:
(72.5ms) BEGIN
(73.6ms) UPDATE `service_requests` SET `actions` = '---\n- spoke_to\n-
left_voicemail\n' WHERE `service_requests`.`nid` = 69524843
(78.2ms) COMMIT
And I have no idea why.
So for some reason, our database guy decided to use the mysql datatype
set. I'm trying to make it work with rails. Here is our column:
actions => set('spoke_to','left_voicemail','emailed')
To make it work I have the following code which i'm sure could be far better:
def actions=(type)
write_attribute(:actions, pack(type))
end
def actions
read_attribute(:actions).split(",") unless
read_attribute(:actions).nil?
end
private
def pack(type)
acs = self.actions
if acs.present? && acs.include?(type)
acs.delete(type)
delete_actions(acs)
else
write_actions(acs, type)
end
end
def delete_actions(acs)
if acs.empty?
write_attribute(:actions, nil)
else
write_attribute(:actions, acs)

MySql query 7 days prior to say days ahead
MySql query 7 days prior to say days ahead
I am trying to construct a mysql query that will pull records from a
timestamp that is from 7 days from todays date and 7 days out from todays
date. I can get the rows that are 7 days either way but not both and cant
seem to figure out how to make this work. Thanks for you help.

NodeJS | Passing an object as function parameter
NodeJS | Passing an object as function parameter
I've had a small problem I couldn't overcome this week, I'm trying to pass
a JSON object as a parameter in a function but it always tells me that I
can't do that, but I don't want to end up sending the 50 values separately
from my json object.
Here is the set up on my app, this is working as intended with express :
app.get('/', routes.index);
Here is the routing index from the previous line of code (Note that I'm
using jade for rendering and I'm using the next function to pass
parameters to it like the name in this one :
exports.index = function(req, res){
getprofile.profileFunc(function(result) {
res.render('index', { name: result });
});
};
Next it calls the function profileFunc from getprofile :
var profileFunc = function(callback) {
var sapi = require('sapi')('rest');
sapi.userprofile('name_here', function(error, profile) {
var result = [profile.data.name];
callback.apply(null, result);
});
};
exports.profileFunc = profileFunc;
Note that I was only able to pass a string result and have it displayed in
the jade render, what I want to do is pass the profile object to use it in
the render to display name, age, birthday but I can't get it to work, it
will either pass a undefined object or not pass.
Thanks for taking time to read this.

Android - How to cache Json using SQLite
Android - How to cache Json using SQLite
My application should work not only in online but also in offline mode.
When my app have internet connection, it will download data (parse from
Json) and save to SQLite database. If I turn off internet, it will get
data from SQLite to display. My problems are how I know when data update
or have new data from server. I want update current records and add new
records when data change.
Ex:
First load - Load 50 records >>> save to SQLite
Second load - Load 30 records (20 current records change & 15 new records)
Total - 65 records in SQLite
Thanks for any help

Execute function only when called by using header:location PHP
Execute function only when called by using header:location PHP
I'd like to be able to only execute a PHP function when I call it by using
header location.
function username() {
$_GET['username'];
}
and only run that function when I call it from a header as followed.
header('Location:www.domain.com/index.php?=getusername')
Once I type that in the URL then the function would execute, how do I
accomplish such use?

closing mongodb connection in node.js while inserting lot of data
closing mongodb connection in node.js while inserting lot of data
I am trying write a program to parse and insert iis logs data in to
mongodb. The files aren't that huge it's around 600 lines. Trying to
convince my management nodejs and mongodb is better for this compared to
.net and sql server :).
Have a look at the below code in nodejs. Logic: I parse every line and
convert into json and insert the save in db. i am using mongonative
driver.
Issue : The db connection gets closed even before all lines are inserted
into the Db.
I see the log file has 6000 lines, but num of records in db is only arnd
4000. I understand it's nodejs's async characteristic, in this how can i
close the connection in more deterministic way (after checking if all
lines got inserted)?
var MongoClient = require('mongodb').MongoClient;
var mongoServer = require('mongodb').Server;
var serverOptions = {
'auto_reconnect': true,
'poolSize': 5
};
var fs = require('fs');
var readline = require('readline');
var rd = readline.createInterface({
input:
fs.createReadStream('C:/logs/Advisor_Metrics/UI/P20VMADVSRUI01/u_ex130904.log'),
output: process.stdout,
terminal: false
});
var mongoClient = new MongoClient(new mongoServer('localhost', 27017,
serverOptions));
var db = mongoClient.db('test');
var collection = db.collection('new_file_test');
var cntr = 0;
mongoClient.open(function (err, mongoClient) {
console.log(err);
if (mongoClient)
{
rd.on('line', function (line) {
if (line.indexOf('#') == -1) {
var lineSplit = line.split(' ');
var data =
{
d: lineSplit[0],

console.log('closing connection');
//db.close();
});
}
});
}
})
rd.on('close', function () {
db.close();
});
Sol 1 : A solution would be parse the json objects and add into an array
and add the array to mongodb. i wouldn't like to do that since that would
like parsing the entire huge log file into memory!, Any other solution?

ASP .NET WebMethods Synchronization
ASP .NET WebMethods Synchronization
I have a webmethod in asp.net .asmx service, wich is supposed to check if
there are records in a DB, and if there are no records it should add a
record
the simplified example of code is like this:
object Mutex = new object();
[WebMethod]
public void InsertIfNotExists(string CLI)
{
lock (Mutex)
{
using (SqlConnection conn = new SqlConnection(ConnectionString))
using (SqlDataAdapter adapter = new SqlDataAdapter())
using (DataSet ds = new System.Data.DataSet()){
{
//I log with log4net
logger.Debug("InsertIfNotExists: Start Function: CLI:" + CLI);
int dummy = 0;
string sql = "SELECT * CLI Promote where CLI=" + CLI + " ";
adapter.SelectCommand = new SqlCommand(sql, conn);
adapter.Fill(ds);
DataTable t = ds.Tables[0];
logger.Debug("InsertIfNotExists: " + t.Rows.Count + " records
found for CLI:" + CLI);
if (t.Rows.Count == 0)
{
logger.Debug("InsertIfNotExists: starting to add to table:
CLI:" + CLI);
DataRow dr = t.NewRow();
dr["CLI"] = CLI;
dr["DateOfSend"] = DateTime.Now;
InsertToTable(t, dr, sql);
logger.Debug("InsertIfNotExists: added to table: CLI:" + CLI +
", starting re-check");
//checking if exist more then one lines - one more time
sql = "SELECT * CLI Promote where CLI=" + CLI + "";
adapter.SelectCommand = new SqlCommand(sql, conn);
adapter.Fill(ds);
t = ds.Tables[0];
logger.Debug("InsertIfNotExists: re-check for CLI:" + CLI + ",
records count=" + t.Rows.Count);
}
logger.Debug("InsertIfNotExists: Finish Function for CLI:" + CLI);
}
}
}
Actually it does more checks and logic, that's why I implement it in .net
and not in the SQL statement itself, but essentially that is it.
Most of the time the code works well, but sometimes I get into race
conditions because of multithreading, though I use lock.
Sample output I got today:

What we see here that 3 threads attempted to insert CLI 0501234567 to the
table in the parallel. Threads 21 and 13 entered the race conditons and
each one inserted 1 record. Then thread 27 also tried to insert a record,
but found existing records and exited.
Why did they do it when locked on mutex?
Additional strange thing is that the thread 21 did never got to the line
logger.Debug("InsertIfNotExists: Finish Function for CLI:" + CLI);
and somehow jumped to starting the function from the beginning for another
CLI.

Changing background color with setInterval
Changing background color with setInterval
Hi I'm trying to make a row of divs blink, but one div should blink at a
time.(not all the divs should blink at the same time [i could do that])..
kind of like the way a traffic light works. each light is part of a row of
lights and each light turns on and off one at a time going through a loop.
in my case the blinking is meant to remind the users that the divs or
clickable.
I put each box in an array but I couldn't figure out how to change the
color of each box in a loop. I guess a way to solve this is by adding and
removing a classes that contains the colors and it should do that after 1
or 2 seconds so setInterval should come in to play. I couldn't figure it
out.
but here is my sad code
var arr =[];
$(".boxes").each(function(){
arr.push($(this));
});
function bgChange(){
for(i = 0; i < arr.length; i++){
arr[i].addClass("red");
}
}
setInterval(bgChange, 2000);
});
I'm looking to forward to seeing the creative ways that you guys could
come up with to make this work.

jQuery shows hidden content on refresh
jQuery shows hidden content on refresh
I use this fancy little jQuery toggle on my site, works great. But now I
have a little larger text area I want to hide, and therefore I've included
it in another php file, but when the site opens\refreshes the content is
briefly shown and then hidden? Have I done something wrong or does it
simply not work right with includes in it ?

c pointer Segmentation fault

*buf points to string "/index.html HTTP/1.0". This while loop stores the

instead and Segmentation fault (core dumped) occurs, what is wrong with
the code and how do i fix it?

Top align 3 floating divs
Top align 3 floating divs
I am trying to get 3 divs that span the width of the page to align to the
top. The idea is to have:
Left Div| Center Div | Right Div
with both the left and right divs taking 25% of the width and the centre
taking 50%. I am using float to get the left and right div's to align to
the sides of the screen. However, my problem is that once I set the center
div to 50% , the right div no longer aligns to the top. Setting 45% width
for the center gets the desired effect in terms of aligning the tops,
however the center div does not take up all the available space
simple HTML demonstrating the problem:
<div class="parent">
<div class="title-bar">Title goes Here</div>
<div class="sidecontent left">Some content</div>
<div class="content">More content and more and more More content and more
and more More content and more and more</div>
<div class="sidecontent right">Some Content</div>
</div>
CSS
.title-bar {
color: @color;
background-color: @title-color;
padding: 5px;
font-family: @font-family;
margin-bottom: 10px;

How to create NSDate timer with selector and time interval
How to create NSDate timer with selector and time interval
Hi I want to create an NSDate object with the following functionality as
the NSTimer line below.
[NSTimer scheduledTimerWithTimeInterval:(slider.value * 60) target:self
selector:@selector(nextFunction) userInfo:nil repeats:NO];
So what is it that appeals to me about the above like is that I can put in
the time I want for it to countdown. Also once the timer has reached 0 the
nextFunction method is called. But I need to use NSDate for a future
operation that cannot be completed with NSTimer. In summary, I want to
create an NSDate that will countdown from whatever current value my slider
holds then upon completion of countdown to call the nextFunction method.
Thanks

SQL Server Table Lock during bulk insert
SQL Server Table Lock during bulk insert
Below is the sample query, consider A
INSERT INTO Target (Col1,Col2,Col3,Col4) ----------------Statement#1
Select A.Col1,B.Col2,A.Col3,C.Col4 ----------------Statement#2
FROM A WITH(NOLOCK) INNER JOIN B WITH(NOLOCK)
ON A.Id = B.ID
LEFT JOIN C WITH NOLOCK
ON C.Id = B.ID
Where A.Id = 11
At which stage the lock will be applied on table [exclusive lock?], how
SQL is going to execute the query?
Result will be fetched from table A, B and C based on join and where clause.
On ready result, start inserting data in table and at same time apply the
lock on table.
So when actual data is written on the page table is locked but not during
select even though it is INSERT INTO with SELECT?

Figuring out R error-handler stack

Having spent more time chasing my tail on this than is healthy, I'm just

In R, [how] can one figure out what error handlers are in force at a given

errors, and I want them to stop!
Thank you -

List all suggested fields given the label
List all suggested fields given the label
I have a field that has a label like First Name. Now I have a user defined
field that he chooses or types. Once he submits the typed label I want to
give him the list of suggested fields that he can map to.
So If user submitted a field labels: Name, First, Hello would get
suggested field First Name for both Name and First.
I am not asking for code. I just need an algorithm I can follow to do this.
Note: I can not use simple CONTAINS method since there might be two or
three words in user submitted label and I need to match any of those words
to existing fields.
Any mapping algorithms would be appreciated. All I need is name of
algorithm and I'll figure it out myself.

How is an event parameter passed?
How is an event parameter passed?
I've noticed in C# I can override methods in the Form() parent class, like
so:
protected override void OnPaint(PaintEventArgs e)
{
}
I don't understand how PaintEventArgs is generated and how/when it is
passed to this function. I've got to assume OnPaint() is called every time
the form needs repainting.
Furthermore, when I create button press events they look like this:
private void button1_Click(object sender, EventArgs e)
{
}
Once again, I don't understand how/why these parameters are passed when a
button click is activated.
I've noticed in C# I can override methods in the Form() parent class, like
so:
protected override void OnPaint(PaintEventArgs e)
{
}
I don't understand how PaintEventArgs is generated and how/when it is
passed to this function. I've got to assume OnPaint() is called every time
the form needs repainting.

Powerpoint VBA/Python: Applying different Font size to words in TextBox Programatically
Powerpoint VBA/Python: Applying different Font size to words in TextBox
Programatically
Aim: To programatically adjust Font size of group of words in a SINGLE
textbox in powerpoint.
Details:
I have two lists:
Labels = ["Mahon Point Retail","Park","Blackpool Drive","Balance","Finglas
Point"]
FontSize = [10,23,15,20,40]
I would like to apply the font sizes in FontSize to the labels in Labels,
by their indexes.
My script thus far:
#add all items in Labels to a single textbox
for i, label in enumerate(labels):
Shape.TextFrame.TextRange.Text += " " + label
#apply font size from FontSize list to its corresponding label
for x, num in enumerate(FontSize, 1):
Shape.TextFrame.TextRange.Words(x).Font.Size = int(num)
The PROBLEM:
I believe the problem lies with the use of "Words(x)" property, is there
any way I can define what a word is? because right now it thinks "Mahon
Point Retail" is 3 words (which it is) but I would like it to see it as a
single word...
Any advice?

How to get jQuery UI tabs element panels and set visibility on some of them?
How to get jQuery UI tabs element panels and set visibility on some of them?
How to get jQuery UI tabs tab elements panel numbers and set CSS style
visibility on some of them?
I want to get elements' panel numbers for tabs and set visibility on some
of the tabs.
<div id="tabs">
<ul>
<li><a href="#">1</a>
:
<li><a href="#">10</>
</ul>
<div id="tab-contents">
<div id="tab1">some content</div>
:
<div id="tab1">some content</div>
</div>
Get elements panel number by eq() or something, then set style visibility
= hidden; or visible; for some tab(s). I tried the following but it does
not work for jQuery 1.10.2 and jQuery UI 1.10.3.
$(function() {
var panelNumber = $("#tabs").eq();
document.getElementById("div#tabs ul li").visibility = 'hidden';
alert(panelNumber);
)};
I want to set specified tabs visible and rest of them hidden for the page
navigation. Also, I do not want DOM to create or destroy tab on tabs for
navigtion using css visibility is needed for the minimized process time
because it gets slower.
Please answer the question for the jQuery 1.10.2 and jQuery UI 1.10.3
because they deprecated length and many others for jQuery UI 1.9.* update.

Can I create a member variable that is a type parameter of a generic?
Can I create a member variable that is a type parameter of a generic?
I have a lot of proxy classes around services, and all look (almost) the
same. Can I reduce code duplication somehow by using a generics singleton
class, that takes the Service and Port class as type parameters?
This is my completely wrong code with what I want to get started:
public class MyProxy<S extends Service, P extends BindingProvider>
{
private static final MyProxy<S extends Service, P extends
BindingProvider> instance
= new Proxy<S extends Service, P extends BindingProvider>();
private S service;
public static MyProxy<S extends Service, P extends BindingProvider>
getInstance() {
return instance;
}
}
The type parameters for MyProxy I assume to be correct.
Can I declare a static instance singleton member variable, and how?
The member variable service should be more easy, can I have a type
parameter as a member, anyway?
How about the return type of getInstance(), how to I write it?

When does Dropbox request token expire?
When does Dropbox request token expire?
I am creating a request token and the authentication url when pressing one
button,
and then a different button (from another app) is making the
authentication itself
(getting the request token and url as parameters , opens web page(the
url), and obtains access token + secret using the given request token)
But I always get an exception that the session has expired.
It only works when it all happens one directly after the other, but not
when it's split up like that.
Is there a way to modify the expiration time? Or maybe a completely
different way to overcome this issue?
I don't think I can create another request token in the second button in
the other app, because then the url won't match
Maybe holding something like session in web?

Accessing vm on host machine through ip address
Accessing vm on host machine through ip address
I'm trying to set up a centOS vm with vmware fusion and get access to it
through the host.
I was following a tutorial online for this as this is my first time doing
this. When I try to access the ip of the vm through chrome on the host, I
should be seeing the apache centOS home page, but I get the "oops, chrome
couldn't connect to the ip".
Any help would be appreciated
edit: I am able to ping to the ip and everything is ok, is it a problem
with the hosts file? Sort of confused

Why do I get this error when I add another constructor?
Why do I get this error when I add another constructor?
I will gladly change the title of this thread to something more
appropriate once I know what subject this falls under.
If I change the parameters of the error-causing constructor, there is no
error.
This error only occurs if I include that exact constructor:
error: no matching function for call to 'Object::Object(Object)'
note: candidates are: Object::Object(Object&)
note: Object::Object()
Code:
#include <iostream>
using namespace std;
class Object {
public:
Object() {} /* default constructor - no problems at all */
Object( Object & toCopy ) {} /* Cause of error, but no error when
commented out */
Object func() {
Object obj;
return obj;
}
};
int main() {
Object o = o.func(); /* this is the line that the error is actually on */
return 0;
}

jQuery, make dropdown menu hide when click elsewhere
jQuery, make dropdown menu hide when click elsewhere
I'm using jQuery to make a simple drop down menu:
<script>
$("#optionsLink").click(function(){
$("#optionsMenu").slideToggle();
});
</script>
It works fine but I would like the menu to disappear when the user clicks
elsewhere on the screen. A bit like your standard windows drop down menu.
Clicking on "File" in my browser will display the drop down menu but
clicking somewhere else, anywhere on a page for example, will hide the
menu.
How would I go about implementing something like this?

Directly start youtube video play from mobile website
Directly start youtube video play from mobile website
Right, second question here. Hope someone is able to help me out :)
I have made a mobile website for our company, it's basically a microsite
that has a few pages, leading to 5 different categories that all have 2-7
links to youtube videos, each with an image of the item as sort of a
"cover" - nicely stacked up under each other. The problem is, that with
the links that I have inserted, using a standard , it sends the viewer on
to youtube, and then they have to play the video from there. What I need
help with is to "skip" the step of the users going to Youtube and having
to press play, and enable viewers to press the "cover image" and the video
loads up right there. So when they go back from full screen video, they
will go back to my site, and not to youtube, having to press back once
more.
I doubt the code is necessary, but here is the div that I am using to link
with:

How to write regex to verify a comma delimited list of values
How to write regex to verify a comma delimited list of values
I am using SobiPro, a directory system for joomla and I have a field that
will have values that contain alphanumerics and hyphens only, so a sample
of what might be in this text field would be:
Toy Kites, Plastic Wheels, 1-Way Gizmos, Metal Spools, 3M Wire Ties
This regex would validate what they enter on the form prior to a field save.
I thought this: (\w+)(,\s*\w+)*
But clearly I am not right, and it does not account for the hyphens.. any
help! thanks!

In Codeigniter fetching symbols from URI intepret differently
I am fetching '$' symbol from uri. And I have already added $ in

MY Output of above code is this ...
$

it is taking segment as differently. that is why i m having issue in

Why does Visual Studio increment the loop pointer before dereferencing it?
Why does Visual Studio increment the loop pointer before dereferencing it?
I checked out Visual Studio 2012's assembly output from the following SIMD

Read Integers and count them, then rewind---C
Read Integers and count them, then rewind---C
this is a small piece of my homework that I am having difficulty with.
There is more to the function then this part but this is all that I am
having difficulty with(There is more after). When I run this, it tells me
that it failed to read the integer file. Can anyone tell me where I should
start looking on where I went wrong?
int * readIntegers(const char * filename, int * numberOfIntegers)
{
FILE* fp = fopen(filename, "r");
int count = 0;
int array;
if(fp== NULL)
{
return NULL;
}
while(fscanf(fp, "%d", &count)>0)
{
(*numberOfIntegers)++;
}
printf("%d\n",*numberOfIntegers);
Compiler warnings, I am not concerned about these since they don't have to
do with that I posted
warning: return from incompatible pointer type [enabled by default]
warning: function returns address of local variable [enabled by default]
warning: unused variable 'array' [-Wunused-variable]
And when it runs this is what I get...
./pa03 inputs/input0 > outputs/output0 ./pa03 inputs/input0 >
outputs/output0
Failed to read integer-file 'inputs/input0', aborting
cat outputs/output0
Failed to read integer-file 'inputs/input0', aborting
cat outputs/output0
Also, the print statement towards the end was diagnostic, later in the
function I will return an array that will display the answer. I was trying
to see if the numberOfInputs got updated to the correct number, which has
not happened so far. I will update my print statemnet to see if it
works...will update.

Test case: 4 1 3 2 5
this is a small piece of my homework that I am having difficulty with.
There is more to the function then this part but this is all that I am
having difficulty with(There is more after). When I run this, it tells me
that it failed to read the integer file. Can anyone tell me where I should
start looking on where I went wrong?
int * readIntegers(const char * filename, int * numberOfIntegers)
{
FILE* fp = fopen(filename, "r");
int count = 0;
int array;
if(fp== NULL)
{
return NULL;
}
while(fscanf(fp, "%d", &count)>0)
{
(*numberOfIntegers)++;
}
printf("%d\n",*numberOfIntegers);
Compiler warnings, I am not concerned about these since they don't have to
do with that I posted
warning: return from incompatible pointer type [enabled by default]
warning: function returns address of local variable [enabled by default]
warning: unused variable 'array' [-Wunused-variable]
And when it runs this is what I get...
./pa03 inputs/input0 > outputs/output0 ./pa03 inputs/input0 >
outputs/output0
Failed to read integer-file 'inputs/input0', aborting
cat outputs/output0
Failed to read integer-file 'inputs/input0', aborting
cat outputs/output0
Also, the print statement towards the end was diagnostic, later in the
function I will return an array that will display the answer. I was trying
to see if the numberOfInputs got updated to the correct number, which has
not happened so far. I will update my print statemnet to see if it
works...will update.
Here is the entire log now.

Example: I have some articles and comments and I want to get something
like this:
[{
title: "Article 1",
content: "Super long article goes here",
comments: [
{ author: "Troll", message: "You suck, Sir!" },
{ author: "SpamBot", message: "http://superawesomething.com/"}
]
},{
title: "Article 2",
content: "Another long article goes here",
comments: [ ... ]
}]
Right now I see two solutions:
Get the articles first, then the comments in a second query with some IN
condition and finally add the comments to the respective articles.
Good old joins. For one I will still have to fiddle around with the data a
lot to get into the structure I want. But beyond that I'm a little
concerned since payload like articles.content will be transmitted for
every comment - unless there is a way to do the join I am not aware of.
I'm hoping that my SQL-illiteracy makes me miss the simple solution.
