Read File in chunks and then read line by line using LineNumberReader.
Repeat this activity
I have a file containing some 6.5 lakh lines. Now I wish to read every
line of this file using LineNumberReader.
However I am encountering an outofMemoryError on adding these many number
of lines to another 3rd party library..
What I intend to do is, read 200000 lines of a file at a time and add
these lines to 3rd party library.
I am using LineNumberReader but I think the entire file is being read
although I have provided condition that when line count reaches 200000
break the loop and add these to 3rd party library..
A code snippet for the same:
LineNumberReader lnr=new LineNumberReader(new FileReader(file));
String line=null;
int i=0;
while(flags)
{
while( null != (line = lnr.readLine()) ){
i++;
3rdPartyLibrary.add(line.trim());
if(i==200000)
{
System.out.println("Breaking");
lnr.mark(i);
break;
}
if(i==400000)
{
System.out.println("" );
lnr.mark(i);
break;
}
if(i==600000)
{
System.out.println("BREAKING " );
lnr.mark(i);
break;
}
}
if(line==null)
{
System.out.println(" FLAG");
flags=false;
}
lnr.reset();
}
What I am intending to do here is read file from 0-200000 in first
iteration. Then read each individual line and add to 3rd party lib.. Once
this is done, read another 200000 lines from (200001-400000) and then
repeat the same activity.
Need help..Can someone please guide..

GLSL Shader Ported From HLSL Is Not Working
GLSL Shader Ported From HLSL Is Not Working
I have this HLSL Shader for blur:
struct VS_INPUT
{
float4 Position : POSITION0;
float2 TexCoord : TEXCOORD0;
float4 Color : TEXCOORD1;
};
struct VS_OUTPUT
{
float4 Position : POSITION0;
float4 Color : COLOR0;
float2 TexCoord : TEXCOORD0;
};
float4x4 al_projview_matrix;
VS_OUTPUT vs_main(VS_INPUT Input)
{
VS_OUTPUT Output;
Output.Position = mul(Input.Position, al_projview_matrix);
Output.Color = Input.Color;
Output.TexCoord = Input.TexCoord;
return Output;
}
Frag
texture al_tex;
sampler2D s = sampler_state {
texture = <al_tex>;
};
int tWidth;
int tHeight;
float blurSize = 5.0;
float4 ps_main(VS_OUTPUT Input) : COLOR0
{
float2 pxSz = float2(1.0 / tWidth,1.0 / tHeight);
float4 outC = 0;
float outA = 0;
outA += Input.Color.a * tex2D(s, Input.TexCoord.xy + float2(0,-4.0 *
pxSz.y * blurSize)).a * 0.05;
outA += Input.Color.a * tex2D(s, Input.TexCoord.xy + float2(0,-3.0 *
pxSz.y * blurSize)).a * 0.09;
outA += Input.Color.a * tex2D(s, Input.TexCoord.xy + float2(0,-2.0 *
pxSz.y * blurSize)).a * 0.12;
outA += Input.Color.a * tex2D(s, Input.TexCoord.xy +
float2(0,-pxSz.y * blurSize)).a * 0.15;
outA += Input.Color.a * tex2D(s, Input.TexCoord.xy + float2(0,0)).a
* 0.16;
outA += Input.Color.a * tex2D(s, Input.TexCoord.xy + float2(0,pxSz.y
* blurSize)).a * 0.15;
outA += Input.Color.a * tex2D(s, Input.TexCoord.xy + float2(0,2.0 *
pxSz.y * blurSize)).a * 0.12;
outA += Input.Color.a * tex2D(s, Input.TexCoord.xy + float2(0,3.0 *
pxSz.y * blurSize)).a * 0.09;
outA += Input.Color.a * tex2D(s, Input.TexCoord.xy + float2(0,4.0 *
pxSz.y * blurSize)).a * 0.05;
outC.a = outA;
return outC;
}
There is a similar one for horizontal...
The idea is, I provide tWidth, tHeight for the texture with and height,
and use that to get the 'size' of a pixel relative to UV coords.
I then use this to do normal blur by taking a weighted average of neighbors.
I ported this to GLSL:
attribute vec4 al_pos;
attribute vec4 al_color;
attribute vec2 al_texcoord;
uniform mat4 al_projview_matrix;
varying vec4 varying_color;
varying vec2 varying_texcoord;
void main()
{
varying_color = al_color;
varying_texcoord = al_texcoord;
gl_Position = al_projview_matrix * al_pos;
}
Frag
uniform sampler2D al_tex;
varying float blurSize;
varying float tWidth;
varying float tHeight;
varying vec2 varying_texcoord;
varying vec4 varying_color;
void main()
{
vec4 sum = vec4(0.0);
vec2 pxSz = vec2(1.0 / tWidth,1.0 / tHeight);
// blur in x
// take nine samples, with the distance blurSize between them
sum += texture2D(al_tex, varying_texcoord.xy + vec2(0,-4.0 * pxSz.y *
blurSize))* 0.05;
sum += texture2D(al_tex, varying_texcoord.xy + vec2(0,-3.0 * pxSz.y *
blurSize))* 0.09;
sum += texture2D(al_tex, varying_texcoord.xy + vec2(0,-2.0 * pxSz.y *
blurSize))* 0.12;
sum += texture2D(al_tex, varying_texcoord.xy + vec2(0,-pxSz.y *
blurSize))* 0.15;
sum += texture2D(al_tex, varying_texcoord.xy + vec2(0,0))* 0.16;
sum += texture2D(al_tex, varying_texcoord.xy + vec2(0,pxSz.y *
blurSize))* 0.15;
sum += texture2D(al_tex, varying_texcoord.xy + vec2(0,2.0 * pxSz.y *
blurSize))* 0.12;
sum += texture2D(al_tex, varying_texcoord.xy + vec2(0,3.0 * pxSz.y *
blurSize))* 0.09;
sum += texture2D(al_tex, varying_texcoord.xy + vec2(0,4.0 * pxSz.y *
blurSize))* 0.05;
gl_FragColor = varying_color;
}
This is a little different, but it's the same logic. I convert pixel
coords to UV coords, and multiply by the blur factor, same as the hlsl
factor. Yet, the glsl one gives me an unblurred, slightly more transparent
version of the original.
What could cause this?
Thanks

I don't understand what exactly Camel does. If you could give in 101 words
an introduction to Camel:
What exactly is it? How does it interact with an application written in
Java? Is it something that goes together with the server? Is it an
independent program?
Can you give me an sample.

Pass a Nokogiri::XML::Element into Delayed Job
Pass a Nokogiri::XML::Element into Delayed Job
I create a variable, called node:
doc.xpath('//Product').each do |node|
and pass it into a delayed job like this:
delay.create_new_book_record(client_id, user_id, node)
and although the variable 'node' I'm passing in looks something like this
just before I pass it into the delayed method:
//node.inspect #=>
<Product>
<RecordReference>9780857380272</RecordReference>
<NotificationType>02</NotificationType>
#...etc
it is passed in like this to delayed job which looks like an empty hash to
me:
INSERT INTO "delayed_jobs"
....
:create_new_book_record\nargs:\n- 1\n- 2\n-
!ruby/object:Nokogiri::XML::Element {}\n"]
And the error that gets thrown when I try to parse node in the delayed_job
task is
wrong argument type Nokogiri::XML::Element (expected Data)
So: how do I pass a Nokogiri::XML::Element into a delayed job task so that
it can be processed within the task?

Multiple templates with same match
Multiple templates with same match
I'm currently stuck on applying multiple xsl:template with the same match
for an element. The example below shows the problem.
Does anyone knows a XSL template that creates the expected output using
two "template match"s? For technical reasons it's not possible to put the
two "template" elements together.
Input
<root>
<elem>123.45</elem>
<elem>789.12</elem>
</root>
XSLT
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:decimal-format name="de" decimal-separator=","
grouping-separator="."/>
<xsl:template match="@* | node()">
<xsl:copy>
<xsl:apply-templates select="@* | node()"/>
</xsl:copy>
</xsl:template>
<xsl:template match="/root/elem">
<xsl:element name="renamed">
<xsl:apply-templates select="@* | node()"/>
</xsl:element>
</xsl:template>
<xsl:template match="/root/elem">
<xsl:element name="elem">
<xsl:value-of select="format-number(.,'#.##0,0000','de')" />
</xsl:element>
</xsl:template>
</xsl:stylesheet>
Output:

I'm currently stuck on applying multiple xsl:template with the same match
for an element. The example below shows the problem.
Does anyone knows a XSL template that creates the expected output using
two "template match"s? For technical reasons it's not possible to put the
two "template" elements together.
Input
<root>
<elem>123.45</elem>
<elem>789.12</elem>
</root>
XSLT
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:decimal-format name="de" decimal-separator=","
grouping-separator="."/>
<xsl:template match="@* | node()">
<xsl:copy>
<xsl:apply-templates select="@* | node()"/>
</xsl:copy>
</xsl:template>
<xsl:template match="/root/elem">
<xsl:element name="renamed">
<xsl:apply-templates select="@* | node()"/>
</xsl:element>
</xsl:template>
<xsl:template match="/root/elem">
<xsl:element name="elem">
<xsl:value-of select="format-number(.,'#.##0,0000','de')" />
</xsl:element>
</xsl:template>
</xsl:stylesheet>
Output:
<root>
<elem>123,4500</elem>
<elem>789,1200</elem>
</root>
Expected output:
<root>
<renamed>123,4500</renamed>

Proerties and dynamic values for display
Proerties and dynamic values for display
In the below code, is it possible to get the value (Value='ABC' or 'CDE' )
dynamically?.
<logic:equal name="screen1" property="prefix" value="ABC">
<td colspan="7"> </td>
</logic:equal>
<logic:equal name="screen1" property="prefix" value="CDE">
<td class="fldlabel"><bean:message key="label.Group"/></td>
<td colspan="5"> </td>
</logic:equal>
In example, I need to implement below logic
if prefix (ABC, LMN, EYX, FDG ) then display text box1 else prefix (GGG,
RRR, RRR, MMM ) then display text box 2 else display nothing.
Please help me to fix this.
if i have function to find like below would be better
if (ABC, LMN, EYX, FDG ) then category 1
if (GGG, RRR, RRR, MMM ) then category 2 .
then i can display the text box based on category.

Import project into Android-Studio
Import project into Android-Studio
I have been given an Android project created in Eclipse which I need to
port to Android-Studio.
I'm using the most up-to-date version of the Android-Studio (0.2.6 build
130.795381) which includes a bundled gradle distribution (version 1.7).
I followed the instructions written here and asked the guy that handed me
the project to provide me with the products of this procedure.
So he did and sent me a "build.gradle" file which suppose to make the
import possible.
I opened the Android-Studio and tried to import the project (using any of
the possible options) and it failed due to:
I tried to download gradle version 1.6 and choose it by selecting the
"local gradle distribution" option, but this time it fails due to:
How can I overcome this problem?

Apache POI - formatting output to HTML
Apache POI - formatting output to HTML
I am writing to an Excel file using Apache POI, but I want my output to be
formatted as HTML not as literal text.
SXSSFWorkbook workbook = new SXSSFWorkbook();
Sheet sheet0 = workbook.createSheet("sheet0");
Row row0 = sheet0.createRow(2);
Cell cell0 = row0.createCell(2);
cell0.setCellValue("<html><b>blah blah blah</b></html>");
What appears when I open the Excel file is:
"<html><b>blah blah blah</b></html>"
but I want:
"blah blah blah"
essentially I am looking for a piece of code along the lines of:
cell0.setCellFormat(CellFormat.HTML);
Except, that doesn't exist.

is an offset between the layers and the googlemap, it disappears if I
switch-on and off some developing tool in a browser, like firebug on

ASP.NET MVC 4 - How to setup HTTPS secured webpage
ASP.NET MVC 4 - How to setup HTTPS secured webpage
I'am writing a web application (ASP.NET MVC4) which has a view to insert
some sensitive user information (not specifically username and password).
I want to secure this screen with the HTTPS protocol and want to store
this information in a secured cookie. First i want to set it up in my
ASP.NET development server of visual studio, afterwards i want to deploy
to azure websites.
I have decorated my controller action with "[RequireHttps]" keyword.
[RequireHttps]
public ActionResult BlobSettings()
{
ViewBag.Message = "Settings";
return View();
}
I have also enabled SSL in my project settings of visual studio. Now two
instances are created in IIS Express (HTTP and HTTPS). When i open HTTPS
url, my whole website is running with the HTTPS Protocol.Not really bad,
but i thought to work with HTTP and HTTPS pages (the other pages should
not be secured).
So my fist question is how can you setup project to work with HTTP and
HTTPS pages and how should you test it with ASP.net developer server?

MaxMind free GeoLiteCity.dat file size issue
Last year I downloaded maxmind free GeoLiteCity.dat from
http://www.maxmind.com website and it's file size around 30MB, but today I
was trying to download new bat file from maxmind
http://dev.maxmind.com/geoip/legacy/geolite/. But it has only 17MB file
size.
So any one know that 17MB file has more ip address than they offered 30MB
file?

Samsung S4 not sending emails when they have an attachment
Samsung S4 not sending emails when they have an attachment
I am using the std email app on the Samsung S4. I cannot send emails when
they have an attachment. The email just sits in the outbox. When I send
the same email without an attachment is gets sent. I have tried all file
formats for the attachment, including word, excel, jpeg in case it was
only affecting certain file types. I have also tried different file sizes,
and it does not matter, even very small attachments of a few bytes will
not work.

Perl use Return as EOL instead of Ctrl-D in Linux
Perl use Return as EOL instead of Ctrl-D in Linux
I'm a beginner to perl, and just started reading user input in my script.
chomp(my $inp = <> );
I have been used to using Return key as the terminator for user input in
other languages, and am unsure how to stop reading user input after
getting a single key press, or some characters followed by Return key. In
perl running on unix, capturing input via the diamond operator, seems to
require pressing Ctrl-D for end of input.
My problem is that I'd like to build an interactive menu where user is
presented a list and asked to press "A", "B" or "C". Once he presses any
of these keys, I'd like to loop according to conditions, without waiting
for him to press Ctrl D. How can I get this level of interactive user
input in perl? In C, I'd use getch. In Bash, I'd use a read and $REPLY.

I need to update a table(MySQL DB) from the JSON received for a different
table controller. I have an "Lists" Controller(for List table in DB) and a
"Table" (for Tables table in DB)Controller. I get the JSON to insert a new
row in Lists table. Now from the JSON received, I need to pick the table
number and update the Tables table too. Below is the JSON recieved

not sure what I am missing. Please advise. Thanks.

Changing aspect ratio of Virtualbox VM under OSX
Changing aspect ratio of Virtualbox VM under OSX
I have a Windows guest on an OSX host, running at 1024x768. I want to use
scale-mode to make the window small enough to have on the side of my
screen, but the problem is that since I maximised the VM in scale mode
earlier, the aspect ratio is now nearer my 16:10. I've tried resizing in
only one dimension, disabling and re-enabling scale mode and also
reinstalling guest additions. A search of the Virtualbox docs does tell me
that maintaining aspect ratio is doable under OSX, but it doesn't say how.
I'd really like to be able to fix this without reinstalling my VM if
possible.
I'm running Virtualbox 4.2.16 r86992 under OSX 10.8.4 with a Window 7 guest.

I'm trying to get a pdf file I'm composing (using LaTeX et. al.) to have a
functional hypertext link that will open a remote pdf file on the web
(ideally in the same PDF viewer I'm using to read the one I'm composing
although I don't think that's possible is it?) and then navigate to a
certain page while fitting the height of that page to the viewing window.
Here's my MWE:

I want this \href[page=10,pdfremotestartview=FitV]{http://www.ctex.org/
documents/packages/layout/geometry.pdf}{link} to take me to page 10 of the
linked PDF file while fitting the height of the page to the window. And while
it does switch to my web browser which then downloads the PDF file and opens
that file (using the browser plugin) in a browser window, the browser/plugin
does not navigate to page 10 or fit the vertical height of the page to the
window.
\end{document}
As I write in the MWE, it works part of the way, but not all the way.
Am I doing something wrong here?
I found this, but I think it's much more complex a problem than the one I
face, and although it was helpful to me, it didn't completely solve the
problem I'm having now.
Any suggestions?

Is turning input and label into block level items okey?
I know that you can't (semantically) do something like:

I am working on the comment_form() for WordPress:
<form...>
<div<
<label>Label<label><input...>
</div>
...
</form>
I am using Foundation's mixin's (sass) to set a grid to label and input.
This mixin will make the label and input a block (those are normally a
inline). Is this, okey? Should I put the label and input in 2 different
div's again and set the grid mixins on those instead?
What I also found in the default comment_form() function is:
<p class="form-submit">
<input name="submit" type="submit" id="<?php echo esc_attr(
$args['id_submit'] ); ?>" value="<?php echo esc_attr(
$args['label_submit'] ); ?>" />
<?php comment_id_fields( $post_id ); ?>
</p>
Because I can't change that p to a div I probably have to recreate the
hole function. I think I need to do this because Foundation will set the
display to block for the input submit. Should I leave it as is or if I
want semantic markup, should I recreate the function?

Play! 2 WS library : Detect and handle closed connection in streaming http
response
In the play WS library, I am using this call to process a streaming http
response:
def get[A](consumer: ResponseHeaders => Iteratee[Array[Byte], A]):
Future[Iteratee[Array[Byte], A]]
I am passing it something like: _ => (Iteratee.foreach(chunk =>
println(chunk)))
Everything works fine, but at some point the connection seems to close and
I don't know how to handle this. I tried adding .mapDone to print out some
stuff when the Iteratee is done, but it never happens.
On this get request, how can I detect that the connection has been closed
and handle that event?

Efficient collision detection between balls (ellipses)
Efficient collision detection between balls (ellipses)
I'm running a simple sketch in an HTML5 canvas using Processing.js that
creates "ball" objects which are just ellipses that have position, speed,
and acceleration vectors as well as a diameter. In the draw function, I
call on a function called applyPhysics() which loops over each ball in a
hashmap and checks them against each other to see if their positions make
them crash. If they do, their speed vectors are reversed.
Long story short, the number of calculations as it is now is (number of
balls)^2 which ends up being a lot when I get to into the hundreds of
balls. Using this sort of check slows down the sketch too much so I'm
looking for ways to do smart collisions some other way.
Any suggestions? Using PGraphics somehow maybe?

Split a vector into three vectors of unequal length in R
Split a vector into three vectors of unequal length in R
a questions from a relative n00b: I'd like to split a vector into three
vectors of different lengths, with the values assigned to each vector at
random. For example, I'd like to split the vector of length 12 below into
vectors of length 2,3, and 7
I can get three equal sized vectors using this:
test<-1:12 split(test,sample(1:3))
Any suggestions on how to split test into vectors of 2,3, and 7 instead of
three vectors of length 4?

How to add a hyperlink dynamically using javascript?
How to add a hyperlink dynamically using javascript?
I am using jQuery's getJson to get a Json object and want to display it on
html page.
I can display them successfully with code like this:
$.getJSON(full_name, {}, function(data) {
$.each(data, function(index, field){
$("div").append(index + " : " + field + "<br>");
});
});
And in json data, there is an item with index called 'reference'. I want
to change its field from a simple text to a hyperlink. And when I click
this link, it will send a GET method request to an url, and display
something get from the server on a new page.
How to change my page to achieve this function?
Thanks, guys!

I am following this example of a Hello World Wicket application
https://www.ibm.com/developerworks/web/library/wa-aj-wicket/
In particular I placed HelloWorld.html in my source directory next to
HelloWorld.java.
My file structure looks like this:
$ tree
..
„¥„Ÿ„Ÿ pom.xml
„¥„Ÿ„Ÿ src
„ „¥„Ÿ„Ÿ main
„ „ „¥„Ÿ„Ÿ java
„ „ „ „¤„Ÿ„Ÿ com

„ „ „¤„Ÿ„Ÿ WEB-INF
„ „ „¤„Ÿ„Ÿ web.xml
„ „¤„Ÿ„Ÿ test
„ „¤„Ÿ„Ÿ java
„¤„Ÿ„Ÿ wicketTest.iml
However when I compile this to a war file, and load in Jetty, i recieve
this error, in the browser:
Unexpected RuntimeException
Last cause: Can not determine Markup. Component is not yet connected to a

i 'm working on my web application security and want to know if i use this:
<machineKey validationKey="AutoGenerate,IsolateApps"
compatibilityMode="Framework45" decryptionKey="AutoGenerate,IsolateApps"

in my web.config , now first user send first request to my site and in
this time validationKey will be create and after that second user send
second request now validationkey will be create again or what ?
and are the same these validations keys for all user ?
what is deference between that config and this?

Eclipse not Starting up. JDK not installing
Eclipse not Starting up. JDK not installing
Okay, so this is a bit of a long and compound question. I intended to
start developing on a different computer while I was away, so obviously
had to go through the process of grabbing everything. I downloaded the 64
bit Android SDK and used the installer to grab everything other than the
disk images for android 4.0.3 (I have a physical 4.0.3 device to test on
with me). So, then I try to start Eclipse.
Failed to load the JNI shared library "C:\Program
Files(x86)\Java\jre7\bin\client\jvm.dll"
So obviously I checked the path and there is jvm.dll in the folder. I went
looking around the internet and the conclusion was to make sure I had 64
bit java, something I knew I already had, anyway in the hope it might fix
the problem I downloaded
jdk-7u25-windows-x64.exe
however when I try to run it I get the following error, which I cannot
find a solution for
This version of the file is not compatible with the version of Windows
you're running. Check your computer's system information to see weather
you need an x86 (32-bit) or x64 (64-bit) version of the program, and then
contact the software publisher.
I am running 64 bit Windows 7 Home Premium (SP1) on an AMD Turion II P540
Dual-Core Processor.
Any suggestions?

How to receive 2 notifications via NSNotificationCenter
How to receive 2 notifications via NSNotificationCenter
I have three methods:
- (void)viewDidAppear:(BOOL)animated
{
[self updateViews];
[[NSNotificationCenter defaultCenter] addObserver:self
selector:@selector(receiveNotification:) name:@"itemQuantityChanged"
object:nil];
[[NSNotificationCenter defaultCenter] addObserver:self
selector:@selector(receiveNotification:) name:[NSString
stringWithFormat:@"Item %@ deleted", itemUUID] object:nil];
}
- (void)viewDidDisappear:(BOOL)animated
{
[[NSNotificationCenter defaultCenter] removeObserver:self];
}
- (void) receiveNotification: (NSNotification *)notification
{
if ([[notification name] isEqualToString:@"itemQuantityChanged"])
[self updateViews];
if ([[notification name] isEqualToString:[NSString
stringWithFormat:@"Item %@ deleted", itemUUID]])
NSLog(@"FAIL!");
}
The main idea is that for this class I need to receive 2 different
notifications and in case of receiving them need to perform different
actions. Is everything ok with the realization? I believe that it is
possible to simplify this code. How to removeObserver correctly? I don't
use ARC.

Parallel Image Proccessing with C# 5.0
Parallel Image Proccessing with C# 5.0
. .
I'm trying to do some image proccessing with C# using that same old GDI
techniques, iterating throught every pixel with a nested for-loop, then
using the GetPixel and SetPixel methods on that (Bitmap) image.
I have already got the same results with the pointers approach (using
unsafe context) but I'm trying now to do the old-school Get/Set-Pixel
Methods to play with my Bitmaps . . .
Bitmap ToGrayscale(Bitmap source)
{
for (int y = 0; y < source.Height;y++ )
{
for (int x = 0; x < source.Width; x++)
{
Color current = source.GetPixel(x, y);
int avg = (current.R + current.B + current.G) / 3;
Color output = Color.FromArgb(avg, avg, avg);
source.SetPixel(x, y, output);
}
}
return source;
}
considering performance with the code above . . . it takes just tooooo
musch to finish while stressing the user out waiting for his 1800x1600
image to finish processing.
So i thought that i could use the technique that we use working with HLSL,
running a seperate function for each pixel (Pixel Shader engine (as i was
tought) copies the function returning the float4 (Color) thousands of
times on GPU to do the processing parallel).
So I tried to run a seperate Task (function) for each pixel, putting these
Task variables into a List and the 'await' for List.ToArray(). But I
failed doing that as every new Task 'awaits' to be finished before the
next one runs.
I wanted to call a new Task for each pixel to run this :
Color current = source.GetPixel(x, y);
int avg = (current.R + current.B + current.G) / 3;
Color output = Color.FromArgb(avg, avg, avg);
source.SetPixel(x, y, output);
At the end of the day I got my self an async non-blocking code but not
parallel . . . Any suggesions guys?
Thanks in advance, Zaid A.

Chrome randomly opening new blank tabs
Chrome randomly opening new blank tabs
Starting a few weeks ago, Chrome has started randomly opening new blank
tabs. It happens mostly when I open an application from the dash, but not
every time. I've tried removing Chrome and re-installing and clearing all
my cookies from Chrome. I haven't figured out any other patterns to this,
but it's pretty annoying. Has anyone else seen this and might know a fix?

Vertically and horizontally centering a matrix bigger than margins
Vertically and horizontally centering a matrix bigger than margins
This question is a follow-up on a previous question: positioning of a
matrix bigger than margins
That question dealt with positioning a pgf matrix that exceeded the
horizontal margins of the page (although I imagine this works for floats
as well?), and both answers provide a solution to the problem.
However, none of those solutions work if the matrix is bigger than the
margins both horizontally and vertically.
How can I make sure that a matrix that is (slightly) too big for the
margins is centered on the page, both vertically and horizontally?
It seems to me that, out of the answers provided in the previous question,
the one based on stackengine might be more up to the task (that's why I
chose to use that one below), but this may well not be the case, and of
course I'm open to all sorts of suggestions.
This is a sample document using the stackengine solution:

How do you hide a div by clicking anywhere outside that div?
How do you hide a div by clicking anywhere outside that div?
I'm displaying an iframe overlay with a z-index of 9999 with 100% width
and height. The actual div inside the iframe is is only 620px wide. The
problem is, I can not hide the iframe by simply click outside that div.
Here's the code I'm using now
$(document).click(function() {
alert("hide iframe");
});
$(".myDivInsideMyIframe").click(function(e) {
e.stopPropagation();
return false;
});

How do you use $sce.trustAsHtml(string) to replicate ng-bind-html-unsafe in Angular 1.2+
How do you use $sce.trustAsHtml(string) to replicate ng-bind-html-unsafe
in Angular 1.2+
ng-bind-html-unsafe was removed in Angular 1.2
I'm trying to implement something where I need to use ng-bind-html-unsafe.
In the docs and on the github commit they say:
ng-bind-html provides ng-html-bind-unsafe like behavior (innerHTML's the
result without sanitization) when bound to the result of
$sce.trustAsHtml(string).

in following example val e contains all the selected clients from select

Hy, I have an XtraReport and I want to export to an Excel File
after that I need to print it , but I loose all the page formats (Header ,
Footer , Repeat on each Page ... )
string reportPath = "c:\\Test.xls";
// Create a report instance.
XtraReport1 report = new XtraReport1();
reportDS c = new reportDS();
c.Init();
// genereaza report
report.DataSource = new reportDS[] { c };
// Get its XLS export options.

// Set XLS-specific export options.
xlsOptions.ShowGridLines = true;
xlsOptions.TextExportMode = TextExportMode.Value;
// Export the report to XLS.
report.ExportToXls(reportPath);
// Show the result.

MongoDB Java driver: distinct with sort
MongoDB Java driver: distinct with sort
Using the MongoDB console I can write a native MongoDB query using
distinct key with a sort like this:
db.mycollection.distinct('mykey').sort('mykey', 1)
Using the Java driver I would expect to be able to write the same query
like this:
myCollection.distinct("myKey").sort(new BasicDBObject("myKey", 1));
However, this doesn't work because DBCollection#distinct() returns type
List and not type DBCursor like DBCollection#find().
How can I write the distinct query with a sort using the Java driver?

Is it possible to use multiple SiteMapNodes with the same Controller and Action, but different titles?
Is it possible to use multiple SiteMapNodes with the same Controller and
Action, but different titles?
I am constructing a Wizard, and use the same "Master" Controller and
Action to orchestrate which child controller and action is called to
implement the step.
I am trying to put together a breadcrumb trail to represent the Wizard
flow, with some difficulty. It is not helped by the fact that one cannot
have multiple "mvcSiteMapNode"s in mvc.SiteMap with the same controller
and action. It seems to need the master controller name ie "Wizard" and
"Index" as opposed to the child controller name ie "Step1" and "Index".
So, on its own, this will work:
<mvcSiteMapNode title="Step1" controller="Wizard"
action="Index" preservedRouteParameters="id"
route="Wizard"/>
However I would like to do, for multiple wizard steps:
<mvcSiteMapNode title="Step1" controller="Wizard"
action="Index" preservedRouteParameters="id"
route="Wizard"/>
<mvcSiteMapNode title="Step2" controller="Wizard"
action="Index" preservedRouteParameters="id"
route="Wizard"/>
But the above will not work, unless there is another way to differentiate
these nodes.
Any wisdom appreciated!
Thanks.

Including jsp images within a jsp file
Including jsp images within a jsp file
I have a page customer.jsp that displays textual information stored within
an object called Customer. On that page, I include an image that is
generated dynamically based on the information stored in Customer, by
including the HTML
<img src="cust_image.jsp" />,
where cust_image.jsp has content type image/jpeg. What is the best way to
make the Customer object available to cust_image.jsp, bearing in mind that
the user could have several open instances of customer.jsp displaying
different customers' details? Is there a way to avoid postfixing
cust_image.jsp with the customer ID?

Firefox: Failure"nsresult: "0x80004005 (NS_ERROR_FAILURE)
Firefox: Failure"nsresult: "0x80004005 (NS_ERROR_FAILURE)
I faced with following error in Firefox 23(this code works fine in IE and
Chrome) during send of XMLHttpRequest:
[Exception... "Failure" nsresult: "0x80004005 (NS_ERROR_FAILURE)"
location: "JS frame :: :: loadUiDesXml :: line 1" data: no] {
message="Failure", result=2147500037, name="NS_ERROR_FAILURE", more...}
I can't google what 2147500037 error means and this error is very strange
for me. This is a piece of code:
var xmlHttp = new XMLHttpRequest();
if (typeof theFile === "string")
{
xmlHttp.open("POST",theFile,false);
}else{
xmlHttp.open("POST",theFile.baseURI,false);
}
xmlHttp.send("");
The file variable is "/emWeb_6-0/des/en/ld117/ept.xml", domen origin
policy shouldn't prevent this request. The most strange thing, that I can
recieve ept.xml in other pages. For example, I can recieve this file
successfully in the following scenario: 1. Recieve ept.xml file on page1.
2. Redirect to page2, recieve ept.xml again 3. Redirect to page3, recieve
some other files, including ept.xml 4. Redirect back to page1, recieve
status.xml, then I try to recieve ept.xml and I get error duting send("")
The network trace is the following:
POST ept.xml
POST ept.xml
POST pch.xml
POST node.xml
POST ftpRslt.xml
POST ept.xml
POST status.xml
POST status.xml
I can't execute xmlHttp.send("") here.
This code works inside frame, I think that it can be related with the
error. Can anyone explain what is the root cause of this?

Flexslider 2 direction nav pointers missing from download
Flexslider 2 direction nav pointers missing from download
Can anyone point me to where I can get Flexslider2's image file for the
direction nav pointers: bg_direction_nav.png
Couldn't work out why I kept getting strange text 'Fl' or 'Fi' in place of
the arrows on the slider. Checking through everything, I have found that
the background image and the css pointing to it is missing from the
download package!
Hopefully the missing image is my missing link... and I can adapt the css?
Can anyone help please?

Why width CSS attribute of label doesn't work without float?
Why width CSS attribute of label doesn't work without float?
I'm new in CSS, and I've got one question. I'd like to make a good simple
form, and there is the following code:
<form>
<div class="row"><label for="name">Some text field</label><input
type="text" name="name" /></div>
<div class="row"><label for="surname">Some another text
field</label><input type="text" name="surname" /></div>
</form>
Some CSS code:
label {
float: left;
width: 230px;
text-align: right;
margin: 5px;
}
.row {
clear: left;
}
I copied and pasted this code from some book. I understand floating,
clearing, but I don't understand why does "width" attribute work with
label (because it inline element) and, in this case, why doesn't "width"
work without "float"? Please, make me clear. Thanks
I'm new in CSS, and I've got one question. I'd like to make a good simple
form, and there is the following code:
<form>
<div class="row"><label for="name">Some text field</label><input
type="text" name="name" /></div>
<div class="row"><label for="surname">Some another text
field</label><input type="text" name="surname" /></div>
</form>
Some CSS code:
label {
float: left;
width: 230px;
text-align: right;
margin: 5px;
}
.row {
clear: left;
}
I copied and pasted this code from some book. I understand floating,
clearing, but I don't understand why does "width" attribute work with
label (because it inline element) and, in this case, why doesn't "width"
work without "float"? Please, make me clear. Thanks

Horizonal LinearLayout with max width TextView
Horizonal LinearLayout with max width TextView
I have a LinearLayout with horizontal orientation and two TextView
children. My goal is to have the left TextView expand to fit its text
content, but only up to a maximum width (to leave room for the right
TextView). The key is I want to be able to express this maximum width in
terms of a percentage similar to the way layout_weight is specified.
The problem with setting the layout_weight is that the TextView is then
unconditionally expanded to fill the maximum width, even if the contents
don't require the extra space.
Here's my current layout:
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<TextView android:id="@+id/subject"
android:textSize="18sp"
android:layout_width="0dip"
android:layout_height="wrap_content"
android:layout_weight="0.8"/>
<TextView android:id="@+id/date"
android:textSize="14sp"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
</LinearLayout>
Thanks!
