Starting Glassfish without Sudo
I am currently having a problem starting Glassfish inside Eclipse on OS X.
It just hangs whilst trying to start the domain.
I think the problem may lie with the permissions of Glassfish - When I use
the 'start-domain domain1' command even in terminal, I must use 'sudo'
otherwise I get a 'permissions denied' error. If I use 'sudo', then the
server starts successfully from terminal.
I think this error may be carrying over into Eclipse - that is, the server
is trying to start but is timing out because Eclipse is not starting the
server with the correct permissions etc.
Is there any way to start the server via Eclipse by giving it root
permissions? Or another solution, is there any way to change the Glassfish
permissions so that it can be started without the 'sudo' command?
Thanks.

Navbar issue in Bootstrap 3.0
Navbar issue in Bootstrap 3.0
I want to create a collapsable, floating navbar to the right hand side of
the Jumbotron in my page. I am using Bootstrap 3.0.
My navbar collapses but the site name disappears when the navbar
collapses. Also the navbar is pinned to the top of my screen rather than
on the right hand side. What am I doing wrong? Thanks for the help.

Change Base Url CodeIgniter and Ionauth
Change Base Url CodeIgniter and Ionauth
This is probably a really simple question but I am entirely new to
codeigniter. I am using ionauth for a secure account system but I would
like to change the url path, simply changing the class name is not
working, it simply gives me a 404 whenever I try access it. I am trying to
change the /auth/ location to /account/ but when I try it by just renaming
class Auth extends CI_Controller { to class Account extends CI_Controller
{ it does not work as expected.
Any suggestions are greatly appreciated, Again I am new to this so please
go easy it's probably a simple fix and me not know code igniter very well.
Thanks, Simon

return code of 256 from python
return code of 256 from python
This is a reposted question from raspberrypi.stackexchange.com. While I am
trying to get something to work on python on the raspberry pi, since it
doesn't involve any pi-specific things, it was suggested by someone I post
here instead. Original post is here.
I am trying to make a web ui to change the date in the rapsberry pi, but I
keep getting a return code of 256.
Currently what I have goes like this:
web page -> submits an ajax request to a python script python checks what
type of command (a time/date command in this case) and pieces together a
string looking like:
sudo date --set="20130901 20:10"
and stores it in a variable commandString. Then python goes:
os.system(commandString)
and the return value is passed all the way up to the web ui where it is
printed out.
I also currently return the commandString value to the web ui too to
verify it and it looks okay.
The problem is that every time I test, I keep getting back 256 as the
error return code. The date on the raspberry pi of course doesn't change
as I manually check it before and after.
However, if I manually go in to python on the raspberry pi and try:
commandString = 'sudo date --set="20130901 20:10"'
os.system(commandString)
It works with no issues. If I try it without sudo then I get a return
value of 256 as well, so I thought maybe it was a permissions issue with
my original script. I tried this link to check my script's permissions and
it seems to be okay? (os.geteuid() is 0)
If it matters, I am using lighttpd and fastcgi to run python from a web
ui. My lighttpd config is currently:
fastcgi.server = (
".py" => (
"python-fcgi" => (
"socket" => "/tmp/fastcgi.python.socket",
"bin-path" => "/var/www/command.py",
"check-local" => "disable",
"max-procs" => 1)
)
)
Any ideas on what I'm missing?
On the original post, it was also suggested I try something like:
echo <password> | sudo -S date --set="20130829 02:02
While it's probably not a good idea to put in my root password like that,
I tried it and got the same result: it works when doing in the
terminal/shell and within the python interpreter, but not via the web ui
to python.

How to pixelate an image with canvas and javascript
How to pixelate an image with canvas and javascript
I've been experimenting a bit with the canvas element and was curious how
to pull off an effect. I've somewhat got what I'm looking for from a
collection of tutorials and demos, but I need some assistance getting the
rest of the way there. What I'm looking for is to pixelate an image on
mouseover, then refocus/un-pixelate it on mouseout. You can see a good
example of the effect at http://www.cropp.com/ when mousing over the
blocks that are below the main carousel.
Here is a link to a fiddle I started. The fiddle won't work because you
can't use cross domain images (womp womp), but you can still see my code
thus far. When mousing over my canvas object I'm able to pixelate the
image, but it's kind of backwards to what I'm attempting to get. Any help
or advice would be greatly appreciated.
var pixelation = 40,
fps = 120,
timeInterval = 1000 / fps,
canvas = document.getElementById('photo'),
context = canvas.getContext('2d'),
imgObj = new Image();
imgObj.src = 'images/me.jpg';
imgObj.onload = function () {
context.drawImage(imgObj, 0, 0);
};
canvas.addEventListener('mouseover', function() {
var interval = setInterval(function () {
context.drawImage(imgObj, 0, 0);
if (pixelation < 1) {
clearInterval(interval);
pixelation = 40;
} else {
pixelate(context, canvas.width, canvas.height, 0, 0);
}
}, timeInterval);
});
function pixelate(context, srcWidth, srcHeight, xPos, yPos) {
var sourceX = xPos,
sourceY = yPos,
imageData = context.getImageData(sourceX, sourceY, srcWidth,
srcHeight),
data = imageData.data;
for (var y = 0; y < srcHeight; y += pixelation) {
for (var x = 0; x < srcWidth; x += pixelation) {
var red = data[((srcWidth * y) + x) * 4],
green = data[((srcWidth * y) + x) * 4 + 1],
blue = data[((srcWidth * y) + x) * 4 + 2];
for (var n = 0; n < pixelation; n++) {
for (var m = 0; m < pixelation; m++) {
if (x + m < srcWidth) {
data[((srcWidth * (y + n)) + (x + m)) * 4] = red;
data[((srcWidth * (y + n)) + (x + m)) * 4 + 1] =
green;
data[((srcWidth * (y + n)) + (x + m)) * 4 + 2] =
blue;
}
}
}
}
}
// overwrite original image
context.putImageData(imageData, xPos, yPos);
pixelation -= 1;

Creating a long precision number in C#
Creating a long precision number in C#
I have a bunch of code written by someone else for a statistics package,
like so:
float myValue = 0.0f;
That makes myValue a single point precision number. Is there a way to make
it go to five decimal places?
Is this the correct way:
float myValue = 0.00000f;

When is a convex polygon inscribable?
When is a convex polygon inscribable?
Defining the diameter of a convex polygon as the maximum possible distance
between all pairs of vertices, can we conclude that the convex polygon is
inscribable (i.e has all its sides as chords of a circle) if the diameter
isn't the diameter of the minimum bounding circle, in which case the
circumscribed circle is the minimum bounding circle?

<input type="text" ng-model="event.name" placeholder="Event Name">
</form>
</div>
</body>
</html>
Now the heading even.name is not getting displayed when I'm using
ng-controller="formController" in that division otherwise its working
fine. When I use ng-controller on the whole page as a division then I get
{{event.name}} and not the content.
How can I display the content of event.name and also use the controller on
form together ?
What mistake am I making ?
I'm having some trouble understanding how to use ng-controller. I've a
form controller in eventController.js.
<html ng-app>
<head>
<script src="angular.js"></script>
<script src="eventController.js"></script>

parsing a JSON fails with missing element in javascript
parsing a JSON fails with missing element in javascript
I am trying to use Youtube's Gdata JSON response in javascript. My code
iterates through the playlist and extract the item data.but for few videos
the rating is not there which throws
"TypeError: item.gd$rating is undefined"
is there a way to check before accessing the element.
this is the code with with i fetch the json response.
var avgrating = item['gd$rating']['average'];
var maxrating = item['gd$rating']['max'];
var minrating = item['gd$rating']['min'];
var numRaters = item['gd$rating']['numRaters'];

Hide Navigation Bar in Interface Builder w/ Storyboards
Hide Navigation Bar in Interface Builder w/ Storyboards
I have a pretty basic storyboard based app, with a UINavigationController,
a main view and a secondary view, both of which are in the navigation
hierarchy. I'm currently hiding the navigation bar on the main view by
using setNavigationBarHidden: as appropriate in viewWillAppear and
viewWillDisappear. It seems like there should be a way to do this in
Interface Builder, rather than in code. Essentially I'd like the options
available in the Simulated Metrics options, but not simulated. Does that
exist?

Algorithm:Sort using Median and Just 1 comparison in $ O(n \log n) $
Algorithm:Sort using Median and Just 1 comparison in $ O(n \log n) $
I am trying to write an sorting algorithm which takes an input array and
produces the sorted array. Following are the constraints for an algorithm.
Time complexity = $O(n \log n)$
Only one comparison operation throughout the algorithm.
We have a function which can provide an median for a set of three elements.
I have tried finding a solution and following is my result.
we use the median function to get the smallest and the largest pair.
Example: Give an array A[1..n], we get the median of the first three
elements, lets call it a set and we receive a $Median$. In next Iteration
we remove the received median from the set and add next element to the set
and again call Median function. This step when repeated over the length
produces a pair of the largest and the smallest element for the entire
array.
We use this pair, use the comparison operation and place them at position
A[0] & A[n-1].
We repeat the same operation over the array A[1..n-2] to get another pair
of the largest and smallest.
We take the median with the A[0] and newly received pair.
Median Value is placed at the A[1].
We take the median with the A[n-1] and newly received pair.
Median Value is placed at the A[n-2].
Step 3~7 are repeated to get a sorted array.
This algorithm satisfies the condition 2 & 3 but not the time complexity.
I hope if someone can provide some guidance how to proceed further.

Easiest to use C API to render utf8 text in OpenGL, outline rendering
prefered [on hold]
What is the easiest C API to render utf8 text in OpenGL.
I would prefer to use outline rendering.
Need to handle non ASCII characters
Huge dependencies would be nice to avoid
My ideal api would be init(),setFont(char*name),drawText(char*text,int
boxWidth,int boxHeight)
I have looked at
http://paulbourke.net/oldstuff/glf/ but this can't handle non ASCII in my
tests
http://quesoglc.sourceforge.net/ looks nice but seems unmaintained and I
get segfaults from it in debian stable
using Freetype directly does not support outline fonts as far as I
understand and freetype seems complicated to use
needs to be cross platform (linux, osx, windows)
So what would you recommend, I do not want C++ libraries as I intend to
use it from D and C bindings are much easier to write.

NSDateFormatter dateFromString conversion
NSDateFormatter dateFromString conversion
I am having problems with conversion of NSString object to NSDate. Here is
what I want to do: I am downloading an RSS Message from the internet. I
have the whole message parsed by NSXMLParser. After that, I have parts
like , or saved to particular NSStrings. I want to convert element (that
includes publication date of RSS Message) to NSDate so that I could
perform some operations on it like on a date object (e.g. sorting, showing
on a clock etc.). Here is the way my looks like:
"Wed, 25 Sep 2013 12:56:57 GMT"
I tried to convert it to NSDate in this way:
*//theString is NSString containing my date as a text
NSDate *dateNS = [[NSDate alloc] init];
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:@"EEE, dd MMM yyyy hh:mm:ss ZZZ"];
dateNS = [dateFormatter dateFromString:theString];*
However, after doing above code, dateNS always appear to be (null).
My question is simple: what is the right way to convert NSString with date
formatted like this to NSDate object?
By the way, I have seen the website
http://www.unicode.org/reports/tr35/tr35-25.html#Date_Format_Patterns It
seems that there are many ways to format particular date, but I could not
find what I am doing wrong.

A variable of which a part is variable
A variable of which a part is variable
I have variables that look something like this:
$INFOMonday
$INFOTuesday
In my Bash script, I would like to use the value of todays variable, so to
say. I extracted the day with:
dayofweek=$(date --date=${dateinfile#?_} "+%A")
What I need help with, is doing the following:
echo $INFO$dayofweek
Is there any way of adding a variable as part of a variables name? For
example, if it's monday, the echo would return the value of $INFOMonday.

Some doubts related to the use of the BorderLayout object
Some doubts related to the use of the BorderLayout object
I am studying Java Swing and I have a doubt related to the use of the
BorderLayout object.
I have this simple example program that create a ToolBar:
package com.andrea.menu;
import java.awt.BorderLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.ImageIcon;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JMenu;
import javax.swing.JMenuBar;
import javax.swing.JToolBar;
import javax.swing.SwingUtilities;
public class ToolBar extends JFrame {
public ToolBar() {
initUI();
}
public final void initUI() {
JMenuBar menubar = new JMenuBar(); // The menu bar containing
the main menu voices
JMenu file = new JMenu("File"); // Creo un menu a tendina
con etichetta "File" e lo aggiungo
menubar.add(file);
setJMenuBar(menubar); // Sets the menubar for
this frame.
JToolBar toolbar = new JToolBar();
ImageIcon icon = new ImageIcon(getClass().getResource("exit.png"));
JButton exitButton = new JButton(icon);
toolbar.add(exitButton);
exitButton.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent event) {
System.exit(0);
}
});
add(toolbar, BorderLayout.NORTH);
setTitle("Simple toolbar");
setSize(300, 200);
setLocationRelativeTo(null);
setDefaultCloseOperation(EXIT_ON_CLOSE);
}
public static void main(String[] args) {
SwingUtilities.invokeLater(new Runnable() {
public void run() {
ToolBar ex = new ToolBar();
ex.setVisible(true);
}
});
}
}
So it create a JToolBar object by the line:
JToolBar toolbar = new JToolBar();
and then it put it in the NORTH position of the BorderLayout object by the
line:
add(toolbar, BorderLayout.NORTH);
Reading the documentation I know that:
A border layout lays out a container, arranging and resizing its
components to fit in five regions: north, south, east, west, and center
My doubt is: the BorderLayout object whom it refers? At the external
JFrame container?
It means that it put the toolbar object in the NORTH position of my
JFrame? Or what?
Tnx

How can I get the number of rows in the image in Objective-C
How can I get the number of rows in the image in Objective-C
I have a TIFF image as an input to me, which I can transform to NSData,
CGImageRef, etc. So, from any of these objects, is there method present to
extract the number of rows present in the image. I need this information
for my project (in MAC OS X).
Also, I don't think that number of rows in the image would be the same as
height of the image.

How to retrieve user's input of label in drop down list in rails 3.2?
How to retrieve user's input of label in drop down list in rails 3.2?
The following simple form takes user input with a drop down list of zone.
The zone_id of user input could be retrieved with
params[:controller][:zone_id].
<%=f.input :zone_id, :label => t('Zone'), :collection =>
Zone.where(:active => true).order('ranking_order'), :label_method =>
:zone_name, :value_method => :id, :include_blank => true %>
In our rails 3.2 app however, we also need to retain the label of user's
input which is zone_name here. Is there a way to retrieve label
(zone_name) of user's input in controller? Thanks.

How to ensure node.js child_process.spawn will write error messages to the console
How to ensure node.js child_process.spawn will write error messages to the
console
I'm having a lot of trouble running child processes and getting their
output written to the console. In this episode, I'm trying to use spawn to
run a windows mklink command. The error is the that I don't have
permission to write the file.
My problem, though, is that the error isn't told to me in any way.
The following prints You do not have sufficient privilege to perform this
operation. to the console:
mklink /D C:\some\path\to\my\intended\link C:\path\to\my\folder
But running this in node.js only gives me Error: spawn ENOENT - which is a
highly useless error message:
require('child_process').spawn('mklink',
['/D', 'C:\\some\\path\\to\\my\\intended\\link',
'C:\\path\\to\\my\\folder'],
{stdio:'inherit'})
I get nothing on the console, despite the stdio:'inherit'. I've also tried
the following:
var x = require('child_process').spawn('mklink',
['/D', 'C:\\some\\path\\to\\my\\intended\\link',
'C:\\path\\to\\my\\folder'])
x.stdout.pipe(process.stdout)
x.stderr.pipe(process.stderr)
But no dice. No console output at all. Note that I do get console output
with exec:
var x = require('child_process')
.exec('mklink /D C:\\some\\path\\to\\my\\intended\\link
C:\\path\\to\\my\\folder')
x.stdout.pipe(process.stdout)
x.stderr.pipe(process.stderr)
This shouldn't need any special knowledge of how windows mklink works - my
problem is simply with error reporting with node.js spawn.
What am I doing wrong here?

Bad gateway 502 after small load test on fastcgi-mono-server through nginx and ServiceStack
Bad gateway 502 after small load test on fastcgi-mono-server through nginx
and ServiceStack
I am trying to run a webservice API with ServiceStack under nginx and
fastcgi-mono-server.
The server starts fine and the API is up and running. I can see the
response times in the browser through ServiceStack profiler and they run
under 10ms.
But as soon as I do a small load test using "siege" (only 500 requests
using 10 connections), I start getting 502 Bad Gateway. And to recover, I
have to restart the fastcgi-mono-server.
The nginx server is fine. The fastcgi-mono-server is the one that stops
responding after this small load.
I've tried using both tcp and unix sockets (I am aware of a permissions
problem with the unix socket, but I already fixed that).
Here are my configurations:
server {
listen 80;
listen local-api.acme.com:80;
server_name local-api.acme.com;
location / {
root /Users/admin/dev/acme/Acme.Api/;
index index.html index.htm default.aspx Default.aspx;
fastcgi_index Default.aspx;
fastcgi_pass unix:/tmp/fastcgi.socket;
include /usr/local/etc/nginx/fastcgi_params;
}
}
To start the fastcgi-mono-server:
sudo fastcgi-mono-server4

Entity Framework Bug, extra decimal places
Entity Framework Bug, extra decimal places
I think I have found a bug in EF5, but I want to verify that this isn't
some weird behavior there is a known fix for (nothing on Google or Bing as
far as I can see).
I'm doing a select on a database value that is 0.06 in a field that is
decimal(18,2). I ran the query I expected EF to generate and got .06 back,
I took the sql profiler query that ef ran an also got .06 back. In my code
however, I got .0675. I checked the EDMX field and it has a matching
precision/scale of 18,2.
My data is "1 version with 4 sets" so my query does a where clause on the
version number and then gets 4 rows back, but only row 3 gets the weird
value. Row 1, 2, and 4 are .03, .04, and .12 and they return as such, but
row 3 is .06 but returns as .0675.
Last thing that could be useful is the EF proxies are the only part that
is wrong. If I select the EF Proxies, that is when this pops up, but if I
do the select into my viewmodel the correct value is returned.
_entities.Sets.Where(x => x.VersionID == versionID) // ---> returns bad value
_entities.Sets.Where(x => x.VersionID == versionID).Select(x => new VM {
Rate = x.Rate}) // ---> returns correctly
Any ideas on this behavior?

jQuery send more then one formdata
jQuery send more then one formdata
Currently my code is
$('#fileupload').bind('fileuploadsubmit', function (e, data) {
// The example input, doesn't have to be part of the upload form:
var adultinput = $('#adult');
data.formData = {adult: adultinput.val()};
if (!data.formData.adult) {
input.focus();
return false;
}
});
Which works just fine to send a post data with adult value from the html code
However there's another input form called thumbsize which i want to send
as well,
I tried
$('#fileupload').bind('fileuploadsubmit', function (e, data) {
// The example input, doesn't have to be part of the upload form:
var adultinput = $('#adult');
var thumbsize = $('#thumbsize');
data.formData = {adult: adultinput.val()};
data.formData = {thumbsize: thumbsize.val()};
if (!data.formData.adult) {
input.focus();
return false;
}
});
But it doesn't seem to work, is there anyway i can go about sending
another parameter?
Thanks!

Websocket Server with Python and Tornado. Always "Connection Closed"
Websocket Server with Python and Tornado. Always "Connection Closed"
I've tried to create a Websocket-Server with Python and Tornado in the
same steps as you can see in this tutorial:
http://mbed.org/cookbook/Websockets-Server
The Server is running and I can see acitvations in the shell. But the main
problem is, that I only get the message "connection closed" when I open
the HelloWorld.html. The same message i can see in the server log and the
websocket handshake is not running. I do not understand the problem and
need help.
The OS is Ubuntu and webserver is Apache2.
many thanks!

Jekill pages on GitHub: how does it work?
Jekill pages on GitHub: how does it work?
I have my gh-pages branch for my project. I am trying to create some
documentation for it. In GitHub, I read that every time I push things onto
the GitHub server, the page is actually fed through to Jakill.
I haven't installed Jakill locally. For now, I just want to use GitHub's,
and essentially act as a "user".
But... how does it actually work? I created a page .markdown, and saw that
the equivalent .html is created -- and marked up. Like this:
---
title: This will be used as the title-tag of the page head
---
Now, let's see.
# Is this working?
But... how do I find out how to actually use Jekill?
I am aware of http://jekyllrb.com/docs/ but I still can't quite figure out
what else I can do, and -- more importantly -- how to simply place a
markdown file that will be "templated" with the current template?
Thank you!

The theory behind frameworks like Prism [on hold]
The theory behind frameworks like Prism [on hold]
I am learning Microsoft's framework Prism and I feel like I am missing
some theoretical stuff. This is not just another library, this is a whole
new way of doing software engineering. Creating flexible and modular big
apps is a big thing, I assume there is something behind.
I don't know what is the theory behind, I just know there is one. Can you
please recommend books or any resources? Or even topic names, then I could
find resources on those myself.
The way I got myself into Prism is I am working on a WPF project that will
grow big after a while, and people recommended Prism as MVVM framework and
much more.

What is cache in C++ programming?
What is cache in C++ programming?
Firstly I would like to tell that I come from a non-Computer Science
background & I have been learning the C++ language. I am unable to
understand what exactly is a cache? It has different meaning in different
contexts. I would like to know what would be called as a cache in a C++
program? For example, if I have some int data in a file. If I read it &
store in an int array, then would this mean that I have 'cached' the data?
To me this seems like common sense to use the data since reading from a
file is always bad than reading from RAM. But I am a little confused due
to this article. It says that reading data from cache is much faster than
from RAM. I thought RAM & cache were the same. Can somebody please clear
my confusion?

Mysql select query bug with '7.56'
Mysql select query bug with '7.56'
This seems to be a very strange issue and I can't seem to get to the
bottom of the cause. When running a mysql select statement we keep getting
no results returned but only when the value comes to a quoted '7.56'. if
we run the same query without the quotes or using a different number it
works as expected. Example queries and results below:
SELECT * FROM orders WHERE itemsTotal = '7.56' LIMIT 0 , 30
MySQL returned an empty result set (i.e. zero rows). ( Query took 0.0334
sec )
SELECT * FROM orders WHERE itemsTotal = 7.56 LIMIT 0 , 30
Showing rows 0 - 0 ( 1 total, Query took 0.0297 sec)
Now if you change the items total to 7.57:
SELECT * FROM orders WHERE itemsTotal = '7.57' LIMIT 0 , 30
Showing rows 0 - 0 ( 1 total, Query took 0.0280 sec)
SELECT * FROM orders WHERE itemsTotal = 7.57 LIMIT 0 , 30
Showing rows 0 - 0 ( 1 total, Query took 0.0284 sec)
This is running mysql 5.5.24 for testing on local host and mysql 5.0.95 in
live environment. Same results when running this query from a PHP file and
phpmyadmin. If anyone can spot an obvious error, please let me know!

Is there a bottleneck here
Is there a bottleneck here
I have run some tests on an IIS (on EC2 @ 7GB RAM + 20 ECUs + ~600MBit
upload) server using JMeter and I'm unsure if there is a bottleneck. It is
serving static content only (images, javascript). JMeter is set to emulate
browser behaviour which downloads all static in parallel (7 per user).
Test 1:
Set to simulate 10 users (7 concurrent connections each)
Averages
Connections = 32
Get requests / sec = 237
CPU = 1%
Bytes sent / sec= ~ 8.5 million
Test 2:
Set to simulate 50 users (7 concurrent connections each)
Averages Connections = 82
Get requests / sec = 236
Bytes sent / sec = ~ 8.5 million
CPU = 1%
The connections average increases yet the requests don't so I suspect
there is something causing a bottleneck. Should the server be able to
handle more requests per second?

Modify File Contents based on starting element/string
I have a HL7 File like:
MSH|^~\&|ABC|000|ABC|ABC|0000||ABC|000|A|00
PID|1|000|||ABC||000|A||||||||||
PV1|1|O||||||||||||||||||||||||||||||||||||||||||

OBX|1|ABC|ABC|1|SGVsbG8=
OBX|2|ABC|ABC|1|XYTA
OBX|3|ABC|ABC|1|UYYA
I have to read only OBX segments and get the text after 5th pipe (|).
Currently I am doing this with:
StreamReader reader = new
StreamReader(@"C:\Users\vemarajs\Desktop\HL7\Ministry\HSHS.txt");
string strTest = reader.ReadToEnd();
string OBX1 = strTest.Split('\n')[3];
File.AppendAllText(@"C:\Users\vemarajs\Desktop\Test\OBX.txt", OBX1 +
Environment.NewLine);
List<string> list = new List<string>();
using (reader)
{
string line;
while ((line = reader.ReadLine()) != null)
{
list.Add(line);
if (line.StartsWith("OBX|") == true)
{
string txt = line.Split('|')[5];
File.AppendAllText(@"C:\Users\vemarajs\Desktop\Test\test.txt",

}

File.AppendAllText(@"C:\Users\vemarajs\Desktop\Test\OBX.txt",

}
This extracts the contents of each OBX segment at element 5 (after 5
pipes) and writes out a file called test.text, in my else statement I am
trying to modify the original HL7 file by deleting OBX|2 and OBX|3 to have
only One OBX|1 as we expect the number of OBX segments inside the HL7 file
to reach 40 or more and we don't wan't to keep those many while returning
the message to its messagebox.
My current code is trying to do this, but adds OBX|1 for each segment that
is not starting with OBX| (this is due my logic), how do I avoid this ?

Python - % Symbol and Invalid Syntax
Python - % Symbol and Invalid Syntax
I'm creating a Python script for my Raspberry Pi Radio. The Pi used
mpd/mpc to play music, and I can type in the following command in Terminal
to see information about the currently playing station:
mpc current -f "[%position%]"
This will show me:
11
As the 11th radio station is playing.
My problem is, when I put this in Python to extract this number to use as
part of my code, it gives me this: (I get a ^ under the first % symbol)
f=os.open("mpc current -f "[%position%]"")
SyntaxError: invalid syntax
This seems odd as I have already used similar commands in a Python script
which have worked, however they have not had the % symbol in them. Such
as:
f=os.popen("mpc current")
I am still learning Python so would appreciate it if someone could correct
me here, as the command seems legit to me, especially with the "" either
side. I even tried using ' instead of ", but if I do, the command doesn't
work.
Many thanks

Access Id of parent entity without actually loading it in EntityFramework code first
Access Id of parent entity without actually loading it in EntityFramework
code first
I have two entities:
public class Parent
{
public Guid Id { get; set; }
public string Name { get; set; }
}
public class Child
{
public Guid Id { get; set; }
public string Name { get; set; }
public Parent Parent { get; set; }
}
I can query Child entity with or without parent by using Include.
public void Test()
{
var child = context.Set<Child>().Include(x => x.Parent)
.FirstOrDefault(x => x.Id == Guid.Parse("<some_id>"));
}
But in some cases I have all Parent entities already cached in memory, And
i want to skip join and query Child entity with only Id propery loaded.
And then get actual Parent from cache by Id:
public void Test()
{
var cachedParents = new List<Parent>();
var child = context.Set<Child>()
.FirstOrDefault(x => x.Id == Guid.Parse("<some_id>"));
var parent = cachedParents.FirstOrDefault(x => x.Id == child.Parent.Id);
}
But child gets loaded with child.Parent == null.
Is there some way to have child.Parent to be loaded or just access
child.Parent.Id (ParentId column) property?
code first
I have two entities:
public class Parent
{
public Guid Id { get; set; }
public string Name { get; set; }
}
public class Child
{
public Guid Id { get; set; }
public string Name { get; set; }
public Parent Parent { get; set; }
}
I can query Child entity with or without parent by using Include.
public void Test()
{
var child = context.Set<Child>().Include(x => x.Parent)
.FirstOrDefault(x => x.Id == Guid.Parse("<some_id>"));
}
But in some cases I have all Parent entities already cached in memory, And
i want to skip join and query Child entity with only Id propery loaded.
And then get actual Parent from cache by Id:
public void Test()
{
var cachedParents = new List<Parent>();
var child = context.Set<Child>()
.FirstOrDefault(x => x.Id == Guid.Parse("<some_id>"));
var parent = cachedParents.FirstOrDefault(x => x.Id == child.Parent.Id);
}
But child gets loaded with child.Parent == null.
Is there some way to have child.Parent to be loaded or just access
child.Parent.Id (ParentId column) property?

UIActivityViewController rotation problems
UIActivityViewController rotation problems
I am having problem with the UIActivityViewController, I instantiate a new
instance each time user presses the 'share' button, but it will not rotate
properly. Is my code lacking something essential?
When I rotate only the status bar and the UIActivityViewController will
rotate (not the view in the background) and also sometimes the
activityView´s size will be wrong.
UIActivityViewController *activityVC;
// Init sharing items and View Controller
NSString *message = [NSString stringWithFormat:@""];
UIImage *imageToShare = [UIImage imageNamed:@"imageName"];
NSArray *postItems = @[message, imageToShare];
activityVC = [[UIActivityViewController alloc]
initWithActivityItems:postItems
applicationActivities:nil];
[self presentViewController:activityVC animated:YES completion:^() {
[activityVC setCompletionHandler:^(NSString *activityType, BOOL
completed) {
// Completed
}];
}];

Naming Convention for ViewModel Child Objects
Naming Convention for ViewModel Child Objects
I am building an ASP.Net MVC application using a ViewModel approach to
keep my domain entities separate from the "models" used by my UI. I am
using the following convention for naming my ViewModel classes.
ViewModelName = ViewName + "ViewModel". For example:
Index + ViewModel = IndexViewModel
So far, so good, this is a fairly common pattern and there is a lot of
guidance on this topic on StackOverflow and elsewhere. My question
concerns child objects used by my ViewModels. If my ViewModel requires a
class with properties identical to my a domain model object, I simply
include the domain model within my ViewModel. For example:
public class PersonViewModel
{
public int PersonID { get; set; }
public Address Address { get; set; }
public string SomeOtherProperty { get; set; }
}
However, I am not sure what naming convention to use when I need a child
object with different properties from my domain model. For example if
Address needed a few additional properties besides what is in the Address
domain model, what should I call it? I considered AddressViewModel like
so:
public class PersonViewModel
{
public int PersonID { get; set; }
public Address AddressViewModel { get; set; }
public string SomeOtherProperty { get; set; }
}
but that just doesn't feel right to me. My gut instinct is that the
ViewModel suffix should only be for the top level ViewModel.
I am looking for suggestions from other developers on what naming
conventions they use in this scenario, specifically what would you call
the child object in this case?

Wired behavior of ExecutorService
Wired behavior of ExecutorService
I have application that pings several IPs at same time. To do that I used
ExecutorService to create threads. Problem is when I call function that is
performing pinging, application ping twice same IP address. When I call
PING function first time, all IPs are pinged correctly and program works
fine but problem is when I submit PINGing again. On second testing
(pinging) each IP address is pinged twice. Here is code that I am using

access public variables of a class from another class of an application C#
access public variables of a class from another class of an application C#
I have a public partial class XYZ: Form. I want to use some public data
(lists etc.) of this class in other class(different file) within same
assembly. XYZ is connected to Database, so it has data, whereas the other
class can get data only from class XYZ.
The other class, let say ABC is a COM visible class library, which has 2
interfaces and 2 classes that implement them. ABC is invoked by Perl and
needs data from XYZ.
How should that be done.
When I try
List<a> lst;
XYZ objxyz= new XYZ();
lst= objxyz.lstxyz;
int count= lst.count();
I get count=0; even though lstxyz has some rows. This happens because when
i create an object through 'new' keyword, it doesnt have any data, so
lstxyz count=0.
How can I get data from other class?
Please help me.Thanks a lot.

How To Remove Object from NSMutableArray After Switching Tab View
How To Remove Object from NSMutableArray After Switching Tab View
So I am trying to remove all objects in an array, [myMutableArray
removeAllObjects], whenever a button is pushed or the tab view changes. I
know that for a button, I can use prepareForSegue:(UIStoryboardSegue
*)segue sender:(id)sender, and it works. But how do I do the same with a
tab?
I am doing this because I am using Parse, a web backend service, and I am
querying for the user's friends and putting it on a tableview, but unless
I remove all the objects from the array, I get duplicates of the names.
Any help is greatly appreciated!!

How to make ServiceStack work with existing MVC/Service/Repository pattern
How to make ServiceStack work with existing MVC/Service/Repository pattern
I am trying to wrap my head around ServiceStack and utilizing it to expose
RESTful services.
I am currently using a MVC/Service/Repository/UnitOfWork type pattern
where a basic operation to get customers might look like this:
MVC Controller Action --> Service Method --> Repository --> SQL Server
My questions are:
What do my SS services return? Domain objects? Or do I return a DTO that
has a collection of customers? And if so, what are the customers? Domain
objects or view models or ??
Should the SS services replace my service layer?
Am I taking the totally wrong approach here?
I guess I am a little confused how to make all of this live side-by-side.
Domain Object
public class Customer
{
public int Id {get;set;}
public string FirstName {get;set;}
public string LastName {get;set;}
}
View Model
public class CustomerViewModel
{
public int Id {get;set;}
public string FirstName {get;set;}
....
}
Controller
public class CustomersController : Controller
{
ICustomerService customerService;
public CustomersController(ICustomerService customerService)
{
this.customerService = customerService;
}
public ActionResult Search(SearchViewModel model)
{
var model = new CustomersViewModel() {
Customers =
customerService.GetCustomersByLastName(model.LastName); //
AutoMap these domain objects to a view model here
};
return View(model);
}
}
Service
public class CustomerService : ICustomerService
{
IRepository<Customer> customerRepo;
public CustomerService(IRepository<Customer> customerRepo)
{
this.customerRepo = customerRepo;
}
public IEnumerable<Customer> GetCustomersByLastName(string lastName)
{

Sketchup API for navigating around a model (eventually to integrate with Leap Motion)
Sketchup API for navigating around a model (eventually to integrate with
Leap Motion)
I'm trying to use to SketchUp API to navigate around 3D models (zoom, pan,
rotate, etc). My ultimate aim is to integrate it with a Leap Motion app.
However, right now I think my first step would be to figure out how to
control the basic navigation gestures via the Sketchup API. After a bit of
research, I see that there are the 'Camera' and the 'Animation'
interfaces, but I think they would be more suited to 'hardcoded' paths and
motions within the script.
Therefore I was wondering - does anyone know how I can write a plugin that
is able to accept inputs from another program (my eventual Leap Motion App
in this case) and translate it into specific navigation commands using the
Sketchup API (like pan, zoom, etc). Can this be done using the 'Camera'
and the 'Animation' interfaces (in some sort of step increments), or are
there other interfaces I should be looking at.
As usual, and examples would be most helpful.
Thanks!

How to select various Task Continuation strategies in TPL
How to select various Task Continuation strategies in TPL
Consider the following continuation:
Task.Factory.StartNew(()=>

As I know the execution will be like this:

MethodB executes after MethodA completes.
MethodC executes after MethodB completes.
What if I wanted the MethodC to continue after MethodA completes.(instead
of waiting for MethodB)
I'm looking for a solution other than manually declaring the task

How can I render 3D objects representing contents (pics, movies) with
HTML5 so I can see them in safari or chrome on my iPhone? I am trying some
options with CSS3 but I was wondering if I can use some other
alternatives.
Thank you. Cyrus

Coding a recursive method in Java that calculates factorials.
Unfortunately it's not working, and I suspect it's because of the 2
parameters that I wasn't too sure about -- which I surrounded with
asterisks. Are those the correct parameters that belong there? Or do I
need to change them to something else and why? Thanks in advance!

How to use multiple Input Dialogs (New to Java)
How to use multiple Input Dialogs (New to Java)
I am trying to create a program that asks a user for a sentinel value (a
value to enter when they want to end the list). It then asks the user to
enter numbers until they re-enter the sentinel value. It then figures out
the max number in the list. I'm very new to Java, and whenever I run the
program is just asks for the sentinel value then does nothing else (never
pops up the second input dialog). I'm sure it's something simple that I'm
doing wrong, but I can't figure it out. Thanks for any help.

git: can I checkout a hotfix branch in a dev environment(with an unmerged
dev branch) or will that cross branches?
I'm new to having git set up for multiple users. I typically used it by
myself with only one branch. I have a questions that I couldn't find safe
answer to via Google:
If I'm currently pulling a feature development branch into my dev server
to test the feature and I suddenly discover the need for a hotfix can I
re-branch(checkout) the hotfix branch (part of master not dev), pull the
files in and start working on/testing a hotfix or will my next "git add ."
add the files from the feature branch(which are still on the server) to
the hotfix branch therefore mixing the two branches?

jdk 1.7.25 doesn't work for my project over windows server 2003
jdk 1.7.25 doesn't work for my project over windows server 2003
I have a jdk version updated from jdk 1.7.21 to jdk 1.7.25, build on
Solaris 10 and production runs over windows server 2003. I have not
updated any java code this time, since build was a success, I would update
java code if compile hits an error, e.g on jdk from 1.6.45 to jdk 1.7.xx,
I have to update a few files to match jdk 1.7 API changes, then it's
running fine, there was a few updates from jdk 1.7.xx to jdk1.7.21, each
time updated was fine. But this time, after build jdk 1.7.25 from 1.7.21
source code, compile was ok, but run time the server runs up ok, but
client is stuck in the middle - there is a SESSION_ADAPTER build failed,
we used OPNORG 1.2 which is over 10 years old, and a 3rd party binary code
only. Wondering where is the really problem on jdk 1.7.25?

Displaying the day on the calendar from the textbox generated
Displaying the day on the calendar from the textbox generated
may i ask on how to display the day (Monday, tuesday,etc) from the textbox
which had a datepicker javascript, into the textbox which would echo the
day from the datepicker.
example: textbox1(datepicker, when the user selects september 12 2013, it
would echo Thursday to textbox2) textbox2 = Thursday. Thank you.

SQLite3 in Embedded Linux NOR MTD Flash
SQLite3 in Embedded Linux NOR MTD Flash
The embedded system has M68K Architecture (MCF547x based), with colilo and
linux kernel 2.6.10 it used MTD (memory Type Device) NOR Flash (Spansion
make). There is around 32 MB of data to be managed (all in forms of
records) and memory available is 40MB as an MTD partition (JFFS2
filesystem). I wanted to understand the performance related problems or
any other memory related problems which i can encounter while doing this
exercise of using SQlite3 (amalgamation version).
By Memory related problem i meant frequent defrag operaton of memory
partition (since that 32 MB of database will be modified almost every
second).
Any experience/insights on this requirement will be very much helpful.
Please share your experience on what has to be taken care.

filesystem). I wanted to understand the performance related problems or
any other memory related problems which i can encounter while doing this
exercise of using SQlite3 (amalgamation version).
By Memory related problem i meant frequent defrag operaton of memory
partition (since that 32 MB of database will be modified almost every
second).
Any experience/insights on this requirement will be very much helpful.
Please share your experience on what has to be taken care.

return Math.max(n%10, maxDigit(n/10));
}
}
console.log(maxDigit(16984));
and the returned value is 9.840000000000003
How can I modifiy this code in order to return just the value 9 ?

How can I use function return val as left val in Python?
How can I use function return val as left val in Python?
I want to make the below c code work in Python, how can I make it?
// low level
typedef int* (*func)(int);
// high level
int a[2];
// high level
int* foo(int i) { return &a[i]; }
// low level
void goo(func f) {
int i = 0;
for(; i < 2; ++i) *f(i) = 7;
}
int main(void)
{
goo(foo);
return 0;
}
When I write a low level function such s goo I want to use the pointer
returned by high level user-defined function foo.
It is really easy in c and I want to make it in Python, How? Thanks!!

something practical, I wanted to create a class where I could connect to

class to convert data and / or array in requests for graphics google...

I know following would be a mess but I couldn't find a better description
to ask. apologies for that.
I had to make a pastebin as I had to point out line numbers.
main app, http://pastebin.com/i9rVyari logs, http://pastebin.com/2c4pU1K8
I am starting many threads (10) in a for loop with instantiating a
runnable class but it seems I am getting same result from db (I am geting
some string from db, then changing it) but with each thread, I get same
string (despite each thread changed it.) . using jdbc for postgresql what
might be the usual issues ?
line 252
and line 223
the link is marked as processed. (true) in db. other threads of crawler
class also do it. so when line 252 should get a link. it should be
processed = false. but I see all threads take same link.
when one of the threads crawled the link . it makes it processed = true.
the others then should not crawl it. (get it) is its marked processed =
true.
getNonProcessedLinkFromDB() returns a non processed link
public String getNonProcessedLink(){ 645
public boolean markLinkAsProcesed(String link){ 705
getNonProcessedLinkFromDB will see for processed = false links and give
one out of them . limit 1 each thread has a starting interval gap of 20
secs.
within one thread. 1 or 2 seconds (estimate processing time for crawling)
line 98 keepS threads from grabbing the same url
if you see the result. one thread made it true. still others access it.
waaaay after some time.
all thread are seperate. even one races. the db makes the link true at the
moment the first thread processes it

If you're already on a child page like /EngineProducts/IsuzuEngines and
try to access a different parent level link like /TransmissionProducts the
IsuzuEngines is left on the link resulting in a page that can't be found.
There's a bunch of overrides for Html.ActionLink and while I looked though
them I don't see a different set of params that looks better.

Find epoch timestamp of Accurev file in my stream OR backing stream?
Find epoch timestamp of Accurev file in my stream OR backing stream?
I'm trying to find the epoch timestamp of whatever version of a file I get
in my stream.
I tried "accurev hist -s stream_name -fx -t highest filename"
That only seems to work if the filename is in the default group of
stream_name. If stream_name inherits the file from a higher stream, I see
"No history corresponding to selection."
I also tried "accurev stat -s stream_name -fe filename" to get the EID,
and then used "-e EID" in the "accurev hist" command. Again, this only
works if the file is in the default group of stream_name, otherwise I get
"No history corresponding to selection."
How can I get the timestamp regardless of whether the file is in my
default group or in the default group of a parent stream?
Thanks.

App opens with Rear Facing Camera launched
App opens with Rear Facing Camera launched
What's the best method of having the rear facing camera run when the app
successfully launches?
I'd like my app to open with a modal view controller first that way the
user can dismiss the camera if they do not wish to take a photo at that
time.
Thanks!

Me.Filter = "[" & Me!cmb_select_field & "] Like " & Chr(34) & "*" &
Me.txt_find_this & "*" & Chr(34)
Which produce a filter [Vendor_name] Like "Vancouver"
Given that cmb_select_field was selected as [Vendor Name] and
txt_find_this had Vancouver entered.
I am working with Access 2010 web pages on sharepoint so I can only use
macros. Is there a way to dynamically create filter strings in Macros. I
can get the string as a Local Variable but when I setfilter I get the
local variable name instead of the string

spyne generates bad WSDL/XSD schema for ComplexModels with ComplexModel children
spyne generates bad WSDL/XSD schema for ComplexModels with ComplexModel
children
I'm trying to use spyne to implement a SOAP service in Python. My client
sends SOAP requests like this:
<ns1:loadServices xmlns:ns1="dummy">
<serviceParams xmlns="dummy">
<header>
<user>foo</user>
<password>secret</password>
</header>
</serviceParams>
</ns1:loadServices>
But I have difficulties putting that structure into a spyne model.
So far I came up with this code:
class Header(ComplexModel):
__type_name__ = 'header'
user = Unicode
password = Unicode
class serviceParams(ComplexModel):
__type_name__ = 'serviceParams'
header = Header()
class DummyService(ServiceBase):
@rpc(serviceParams, _returns=Unicode)
def loadServices(ctx, serviceParams):
return '42'
The problem is that spyne generates and XSD like this:
...
<xs:complexType name="loadServices">
<xs:sequence>
<xs:element name="serviceParams" type="tns:serviceParams"
minOccurs="0" nillable="true"/>
</xs:sequence>
</xs:complexType>
<xs:complexType name="serviceParams"/>
...
which is not what I want because essentially it says that "serviceParams"
is just an empty tag without children.
Is that a bug in spyne? Or am I missing something?

Get request parameters in controller's constructor Zend Framework 2
Get request parameters in controller's constructor Zend Framework 2
I have 10 actions in one Controller. Every action required ID from
request. I want to check ID in constructor for every action, so I want
avoid to write the same code 10 times in every action.
obviously, In constructor I can not use functions like:
$this->params()->fromQuery('paramname'); or
$this->params()->fromRoute('paramname');
So, the question is how to get request params in controller's constructor?

IBM Worklight: No SessionManager in calling Worklight adapter
Sometimes when Worklight adapter is invoked, the following error "No
SessionManager" is encountered in server log. When the adapter is invoked
again, result is returned. I have checked that the session ID remains the
same.
May I know what is the possible reason to have this kind of error? Thanks!

R issue: How to introduce tags from dataframe to specific tag documents inside a corpus
R issue: How to introduce tags from dataframe to specific tag documents
inside a corpus
Is it possible to add an additional tag to a corpus document which has
another tag with a specific value?
I have a corpus with 20 docs. The docs have a character ID set. On the
other hand I have a dataframe with some of the 20 docs. Beside the ID the
dataframe has a tag column. This tags have to be set to all corresponding
docs inside the corpus. How would you find the right doc in the corpus for
all elements inside the dataframe and set the corresponding tag?
Example: library("tm") data(crude) # a corpus with 20 docs meta(crude,
type="local", tag="alphanumID") <- letters[1:20] # adding some additional
IDs to the corpus
mydf <- data.frame(cbind(SomeTag=sample.int(1e8, size = 15, replace =
FALSE, prob = NULL),
alphanumID=paste(letters[1:15], 16:30, sep="")))
# Creating a dataframe with similar IDs
mydf <- mydf[sample(nrow(mydf)),] # permutation of elements (rows)
rownames(mydf) <- 1:15 # overwriting the rownames
mydf
> mydf
