Tinymce url needs to be versatile
I need relative path in links which don't have full url and i don't need
relative path in url which have full url.
When i insert in tinymce:

2. But i don't need full url (relative path) in: "javascript:"
While initializing tinymce i am currently using relative_urls as false and
it is causing problem in number 2 problem as mentioned above. And main
problem is i need it in same page and in same textarea.

phpmyadmin, import CSV-load date with line breaks?
phpmyadmin, import CSV-load date with line breaks?
I have the following problem.
I have a CSV file with articles (for joomla) that I want to import to my
server through phpmyadmin. Now after figuring out how to import date
format i came across my second problem, and that is how to import the
articles that is stored in a cell that is in a csv-load date file????
The problem is that when importing it, I don't see any line breaks in the
articles, not in joomla and not in the html code that sould be stored in
phpmyadmin
So I hope that somebody can help me with that Thanks in advance

Same column for two different relational entities with doctrine
Same column for two different relational entities with doctrine
Well, I have these three tables:
likes
id_like | post | post_type
post: it has the post id where the "like button" was triggered.
post_type: it has the type of the post, it could "article" or "comment".
Comment
id_comment | body
Article
id_article | body
I am trying to create the models "Article" and "Comment" where each one
can has an array of its likes. For example, I have tried this with:
Model Like
/**
* @Entity
* @Table(name="likes")
*/
class Like
{
/**
* @Id @Column(type="integer", nullable=false, name="id_like")
* @GeneratedValue(strategy="AUTO")
*/
protected $id;
/**
* @Column(type="integer", nullable=false, name="like_type")
*/
protected $type;
Model Article
namespace models;
use \Doctrine\Common\Collections\ArrayCollection;
/** * @Entity * @Table(name="article") */ class Article {
/**
* @Id @Column(type="integer", nullable=false, name="id_article")
* @GeneratedValue(strategy="AUTO")
*/
protected $id;
/**
* @OneToMany(targetEntity="Vote", mappedBy="article")
* @JoinColumn(name="id_article", referencedColumnName="post")
*/
protected $likes;
My first problem comes when I try to get the "likes" from the article. If
I do:
$likes = $article->getLikes();
I get this error:
Severity: Notice
Message: Undefined index: article
Filename: Persisters/BasicEntityPersister.php
Line Number: 1574
Now, the second problem (or question) that eventually will come is about
the "Comment" model. Is be possible do a OneToMany from Comment to Likes
using as the same way as Article do?

How to show properly display generated TinyMCE content
How to show properly display generated TinyMCE content
I would like to display in a box the saved content of a TinyMCE generated
bit of text. The text does not appear formatted like I'd like the HTML to
appear. The database has the following saved:
<p><strong>test</strong></p>
Do I need to convert this back to HTML encoding? I would like the content
to actually appear like it was formatted in TinyMCE. Is this possible?

twisted: test my service's stop sequence
twisted: test my service's stop sequence
We have a complex multiservice that needs to do some fairly intricate
accounting when shutting down in order to implement a "graceful" shutdown.
I'm trying to write tests for this under trial. The issue is that the
reactor is effectively a process-global resource, and shutting down my
service means that trial's reactor is also stopped, which (of course)
makes it explode.
This is documented to be a no-no in trial, but I need some kind of
workaround that allows me to write my tests. My first thought was to use a
mock.Mock, but this means we're not really using a reactor that's shutting
down, which isn't going to give me behavior that's faithful to the actual
shutdown process.
I believe what I need is a way to separate trial's reactor from the
reactor of my service-under-test. Sharing a mutable resource between the
test system and the system under test is surely an anti-pattern.

Trouble using cuechange event and track metadata (HTML5 video)
Trouble using cuechange event and track metadata (HTML5 video)
I've Googled and search for a few days, but I can only find HTML5 video
track examples that talk about subtitles, and the ones I've found aren't
really complete. Basically, what I would like to do is the following:
-When I enter a cue, I need to access the data for the cue.
-The text data (at least I think it's the text...) contains a number. That
number corresponds to an img id elsewhere in my document. I do something
to the image then.
This seems like it should be really simple, but I'm not exactly sure where
to start. I'm using Jquery.
Here are some snippets of my code:
In my $(document).ready function, I have the following...
var t = $("#track1")[0];
t.addEventListener("cuechange", function () {
var mycue = this.track.cues[0];
var imgnum = mycue.text;
var image = $("img#" + txt);//I'm not worried about this part yet...I
never get here
//perform actions on image...
});
My html video tag looks like this:
<video id="Video1" controls='controls' width="100%" autoplay>
<source src="videos/video-part1.mp4" type="video/mp4" >
<track id="track1" kind="metadata" src="test.vtt" srclang="en-us" />
HTML5 Video is required for this example. </video>
And my Webvtt file looks like this (The numbers below the time ranges are
the slide numbers I need to use)
WEBVTT
Test1
00:00:00.000 --> 00:00:23.999
00001
Test2
00:00:24.000 --> 00:01:19.999
00121
Test3
00:01:20.000 --> 00:01:39.999
00793
When I debugged my code in Chrome the first few times, there didn't appear
to be any cue data associated with the track (I checked the cues elsewhere
in the code and they were empty). The cuechange event is also not being
hooked. After a while, Chrome started giving me the error about
referencing text tracks across domains. I don't know why it suddenly
started doing that.
But anyway, in short...
-I don't know how to bind something to the cuechange event correctly
(apparently), or the event where you enter a cue either for that matter.
-I don't know how to access the data I need to use.
Just so you know, I also tried kind="captions" and kind="subtitles".
Neither one of those worked for me either. Some help would be lovely. :)

Phone number list manipulation Nested SED
Phone number list manipulation Nested SED
Still about phone manipulation. I have a list of phone numbers as per below:
(855) 422-6932
(899) 991-9054
(855) 912-7326
(833) 390-8072
(867) 934 2368
(898) 731 7056
(899) 251 5372
(855) 137-6285
(855) 294-5537
(844) 680-7479
If you notice the phone number pattern on line number 5 to 7 it has no "-"
how can I insert "-" using sed or awk?
It feels like i will have to do some sort of nested sed conditional
substitution if it is possible at all.
can anyone help?

Android use namespace as prefix for attributes in library
Android use namespace as prefix for attributes in library
I am trying to implement the ActionBar through the support library, v7.
Because I want to support the app for Android 2.1 (API level 7) and above.
I read in http://developer.android.com/guide/topics/ui/actionbar.html
following: "Using XML attributes from the support library Notice that the
showAsAction attribute above uses a custom namespace defined in the tag.
This is necessary when using any XML attributes defined by the support
library, because these attributes do not exist in the Android framework on
older devices. So you must use your own namespace as a prefix for all
attributes defined by the support library."
My question is how do I use my own namespace as a prefix for all
attributes defined by the support library?
Step by step explanation please! //Thanks.

Why does the .net SSLStream not show TLS in Wireshark?
Why does the .net SSLStream not show TLS in Wireshark?
So, I was curious about how the traffic through a .net SSLStream would
look like and I set up a small client/server application you can find
here.
It establishes a TLSv1 connection between the two hosts, with the
following parameters:
Cipher: Aes128 strength 128
Hash: Sha1 strength 160
Key exchange: RsaKeyX strength 2048
Protocol: Tls
Is authenticated: True as server? True
IsSigned: True
Is Encrypted: True
So I expected to see some TLSv1 in my wireshark traces between the two
hosts, but there was not a single one.. I had some SSL and TLSv1.2 in the
protocol-field, between my computer and some other hosts, but not between
the hosts communicating through the .net SSLStream
Is this how it is supposed to look?
I expected something like this: (found on google)..

What is the best way to organize my active directory structure
What is the best way to organize my active directory structure
i would like to adopt the best structure for my active directory domain,
in order to be able to apply GPO efficiently. Here is my schema :
CompanyName\ServiceName{Users, Groups, Workstations, Laptops}
My first question is about geographical sites : we have two geographical
sites, is it better to create this sort of hierarchy :
CompanyName\GeographicalSiteName\ServiceName{Users, Groups, Workstations,
Laptops} or handling geographical sites GPO using Sites policy ? Indeed,
this organization can lead to have to duplicate some services, if they are
split on 2 sites.
My second question is about the {Users, Groups, Workstations, Laptops}, do
you think there is better organization ?
Thanks very much

how to go from String to method
how to go from String to method
I hope the title was understandable .
I have 4 functions :
public void seta1(...);
public void seta2(...);
public void seta3(...);
public void seta4(...);
Now the user gives me a String with the methods partial name ( say String
input = "a1"). Is there a way ( without using case option) to activate the
correct method ?
something like : (set+input)();

Ada enumerations with duplicate values

I'm trying to have a device register as an enumeration. Reading from the

I wrote the following code
type Soft_Reset is (Done, Pending, No_Action, Reset);
for Soft_Reset use
(Done => 0,
Pending => 1,
No_Action => 0,

But this throws an error

HTML script injection via javascript

I have a text field where user can fill href tag script which I have to
show as a link later on. But your can enter some malicious script like
alert message and more like that which will cause execution on unwanted
script at the point where I use that text field value to display. My
question is that how can I restrict user to only enter href tag releated
entry in text field and restrict other script to enter. Thanks In advance.

Using g.applyLayout in controller breaks unit test
Using g.applyLayout in controller breaks unit test
I've got a controller method that needs to return a JSON map, one of the
items inside of which is html from a template. I'm using code like
map['html'] = g.applyLayout(name: 'layoutName', g.render(template:
'template', model: [...])
...
render(map as JSON)
And I've got at Controller unit test that calls this method. However when
I run the test, I get the following exception:
java.lang.IllegalStateException: Cannot return Sitemesh factory it has not
been set!

If I take out the g.applyLayout() and just use the g.render() the test
runs. What am I doing wrong?

Deserialize error with jackson json in case of list in java
I have create a JSON with Jackson based on this class:

I have defined two constructor for each class and I use it for the

Installing C compiler, JDK etc. in Ubuntu
Installing C compiler, JDK etc. in Ubuntu
I am a new to Ubuntu. I have used Windows before, but I am not able to
install new software in Ubuntu from the offline setup files, so I don't
know how to install software in Ubuntu. Please tell me how to install new

Wireless is hard blocked on Asus x75a can't unblock!
Wireless is hard blocked on Asus x75a can't unblock!
I have an Asus x75a laptop on which I have recently installed Ubuntu 13.04
alongside Windows 8. I everything seems to be running smoothly except for
the fact that I can't get the Wi-Fi to work! When I click in the Wi-Fi
widget in the upper right-hand corner of the desktop, Wi-Fi is greyed out
and says that it is disabled by hardware switch. This is odd because my
computer model doesn't HAVE a hardware switch for wireless; it's turned
off and on by the Fn+F2 combination in Windows, but that doesn't seem to
be working here. I don't have any Ethernet or anything else besides
wireless to hook up to so it's a real problem.
I am extremely new to Linux, and I haven't found any good answers for this
problem online.
My computer has an internal Quallcom Atheros AR9485 Wireless Network Adapter.
Here's what I get when I run rfkill list:
0: phy0: Wireless LAN Soft blocked: no Hard blocked: yes 1: asus-wlan:
Wireless LAN: Soft blocked: no Hard blocked: no
I have tried both rfkill unblock all and rfkill unblock 0, both to no avail.
When I go into the settings app and click on network, I see the word
Wireless next to a virtual switch in the off position, but when I flip it
to on it immediately flips back to off.
It's not a problem with the Wireless adapter cuz it works fine in Windows.
It makes no difference whether it's on our off when I exit Windows.
Yes, wireless is enabled in the BIOS (or UEFI, our whatever it's callled
nowadays...)
When I installed Ubuntu, I did not connect to the internet during
installation cuz the only network I have at home is only for wireless
printing etc and no internet so I figured it was useless to connect it to
a dead network. So when I realized that I had this problem, I figured I
should try reinstalling Ubuntu WITH it connected to my dead network to see
if that would get the Wireless working. But when I went to connect to a
network in the reinstallation process, I realized it didn't list my
network at all, but rather listed my ATHEROS AR9485 WIRELESS NETWORK
ADAPTER as an available "network"! But I couldn't connect to this
"network" cuz it insisted I needed a password, which I thought was weird.
Network Adapter don't have password do they? I've never found anything
saying mine has one and I've never created one for that matter. So I
realized it was pointless and cancelled the reinstallation.
That's all the background info I can think of to provide you at the moment.
please help!!!!!!
Thanks!!!!

Confused about BER (Basic Encoding Rules)
Confused about BER (Basic Encoding Rules)
I'm trying to study and understand BER (Basic Encoding Rules).
I've been using the website http://asn1-playground.oss.com/ to experiment
with different ASN.1 objects and encoding them using BER.
However, even the simplest encodings seem to confuse me.
Let's take a simple ASN.1 schema:
World-Schema DEFINITIONS AUTOMATIC TAGS ::=
BEGIN
Human ::= SEQUENCE {
name UTF8String
}
END
So basically this is just a SEQUENCE with a single UTF8String type field
called name.
An example of a value that matches this sequence would be something like:
{ "Bob" }
So, using http://asn1-playground.oss.com/, I produce the BER encoding of
the following data:
some-guy Human ::=
{
name "Bob"
}
I would expect this to produce one sequence object, followed by a single
string object.
What I get is:
30 05 80 03 42 6F 62
Now, I understand some of this encoding. The first octet, 30, is the
identifier which tells us that a SEQUENCE type is the first object. The 30
is 00110000 in binary, which means that we have a class of 0, a PC
(primitive/constructed) bit of 1 (meaning constructed), and a tag number
of 10000 (16 in decimal) which means SEQUENCE
So far so good. The next value is the LENGTH in bytes of the SEQUENCE,
which is 05.
Okay, still so far so good.
But then... I'm totally confused by the next octet 80. What does that
mean??? I would have expected a value of 00001100 (for tag number 12,
meaning UTF8String.)
The bytes following the 80 are pretty straightforward: the 03 means Length
of 3, and the 42 6F 62 is just the UTF8String value itself, "Bob"

the previecontroller is displayed but the transition is not animated. it
just appears without any animation.

How to access data of nested objects in LinkedHashMap
How to access data of nested objects in LinkedHashMap
Data present in LinkedHashMap:-
{
contacts={
id={
version=6,
lastUpdatedTimeStamp=1377,
contactID=23,
firstName=B,
lastName=K
}
}
}
Here, "contacts" & "id" are objects.
I am able to get the values of "contacts" :
LinkedHashMap map = restClient.getLinkedHashMap();
Object contactObj = map.get("contacts");
But how to get the value of "firstName"?
Any help or guidance will be well appreciated.

Help with formulating a linear programming problem
Help with formulating a linear programming problem
I have the following linear programming problem I would like to be verified:
I have sketched the problem in the following picture:
Here is my attempted solution:
I figured that I have ten variables (corresponding to the colored lines,
between each building): $x_1, x_2, ..., x_{10}$ which are the amounts (in
tons) of raw materials from Source 1 --> Plant A, Source 1 --> Plant B,
Source 2 --> Plant A, Source 2 --> Plant B, Plant A --> Market 1, Plant A
--> Market 2, ............, Plant B --> Market 3.
The formulation I get is the following:
$$\text{minimize}\;\;\; 1x_1 + 1.5x_2 + 2x_3 + 1.5x_4 + 4x_5 + 2x_6 + 1x_7
+ 3x_8 + 4x_9 + 2x_{10}$$ $$\text{subject to}\;\;\;x_1 + x_2 = 10$$
$$\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;x_3 + x_4 = 15$$
$$\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;x_5 + x_8 = 8$$
$$\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;x_6 + x_9 = 14$$
$$\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;x_7 + x_{10} = 3$$
$$\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;x_1 \ge 0, x_2 \ge 0, \cdots, x_{10}
\ge 0.$$
I would appreciate if someone could verify the correctness of my answer :)

D3js map color keys?
D3js map color keys?
Background concept: Elevation maps and their color keys for human readers
require a more detailled coverage of lower elevation (<200m), where 80% of
the world population lives.
D3 project:
Given data elevations levels (m) such : 0, 50, 100, 200, 500, 1000, 2000,
3000, 4000, 5000m.
How to add a non linear color ramp key, with ticks at 0, 50, 100, 200,
500, 1000, 2000, 3000, 4000, 5000m.
Comment: I currently goes with an unsatisfying linear ramp code, see this,
which cut my 5000m into 10 equal spans of 500m :
I should actually have 4 differents greens standing for 0, 50, 100, and
200m and less browns/greys/whites.
Var color declaration. Set up the color ramp table by stating the points
where I have color shifts :
// Color-values equivalence var color_elev = d3.scale.linear() .domain([0,
200, 2000, 5000]) // values elevation (m) .range(["#ACD0A5", "#E1E4B5",
"#AA8753", "#FFFFFF"]) // colors .interpolate(d3.interpolateHcl)
each of these 3 spans should indeed have linear color changes.

C# How do I parse a text file of data of unknown row size to a 2D array?
C# How do I parse a text file of data of unknown row size to a 2D array?
I can easily pass a data file to a 2D array if I know the size of the data
file, but thats pretty pointless when you want to add and remove data.
How can I instantiate a 2D array of that Data rows length that is global
and not out of scope to the rest of the program?
Here is the usual code, for an array of 4 rows and 6 columns, but I want
to add/remove data to the data file making it of unknown length in rows.
string[,] allStudentData = new string[4, 6];
string[] allStudents = File.ReadAllLines("data.txt");
for (int i = 0; i < allStudents.Count(); i++)
{
for (int j = 0; j < 6; j++)
{
string[] DataIn = allStudents[i].Split(',');
allStudentData[i, j] = DataIn[j];
}
}
Thanks for your ideas :-)

Can you register multiple system events with one broadcast receiver in android
Can you register multiple system events with one broadcast receiver in
android
I can't find this in the online documentation, but this is what I would
like to do:
In the AndroidManifest.xml add the following receiver:
<receiver android:name="my.package.SystemBroadcastReceiver">
<intent-filter>
<action android:name="android.intent.action.BATTERY_LOW" />
<action android:name="android.intent.action.DEVICE_STORAGE_LOW" />
<action android:name="android.intent.action.LOCALE_CHANGED" />
<action android:name="android.intent.action.TIMEZONE_CHANGED" />
<action android:name="android.intent.action.DATE_CHANGED" />
<action android:name="android.intent.action.AIRPLANE_MODE" />
<action
android:name="android.intent.action.CONFIGURATION_CHANGED" />
</intent-filter>
</receiver>
In the SystemBroadcastReceiver.java add the following code:
@Override
public void onReceive(Context context, Intent intent) {
if (intent.getAction().equalsIgnoreCase(Intent.ACTION_BATTERY_LOW)) {
// stop the app to save battery
}
if (intent.getAction().equalsIgnoreCase(Intent.ACTION_BATTERY_OKAY)) {
// start the app again
}
// if (...) { // next action, etc}
}
I would like to add all system events the app uses in this one receiver.
Or is this bad practice? Also use this receiver to start a Service like
BluetoothService, WifiService, NFCService, etc.
I have seen many tutorials that only mention one system event, not more
than one. Is that for a specific reason?

How to move objects with Window's C++ Graphics (GDI+) library?
How to move objects with Window's C++ Graphics (GDI+) library?
So far, I've only copy/pasted the example that Microsoft has here (but I
removed #include ).
I'm trying to figure out how OnPaint is continually called (as to have
moving objects), but it doesn't seem to be called more than once.
How do I use the standard Windows C++ graphics library (i.e. GDI+, or
another standard Windows API) to create a moving object? Must I call
OnPaint myself? Or is there an easy fix to make it continually be called?
Or is it just not possible?

Problems getting data from XML using Nokogiri and Rails
Problems getting data from XML using Nokogiri and Rails
I'm trying to get information from a XML file with Nokogiri. I can
retrieve file using
f = File.open("/my/path/file.xml")
cac=Nokogiri::XML(f)
And what a get is a fancy noko:file. My row tags are defined like
<z:row ...info..../>
like
<Nokogiri::XML::Element:0x217e7b8 name="z:row"
attributes=[#<Nokogiri::XML::Attr:0x217e754 name="ID_Poblacio" value="3">

s=cac.at_xpath("/*/z:row") or
s=cac.at_xpath("//z:row") or
s=cac.at_xpath("//row") or
s=cac.at_xpath("z:row")...
Probably I'm really fool but I cannot figure out which can be the issue.
Does anyone face this problem?
Thanks in advance.
P:S I tried to paste my cac file directly from bash but something wierd
happens with format so I remove it from question. If anyone can explain
how to do it I will appreciate it.

Change a variable value inside a Jquery .filter() function
I have a table which has id 'myTable'. Now there is a textbox in which I
write down the item name to find whether it exists in the myTable cell or
not. To do this I have written the following code -
var retval=0;
var search = $("#searchitem").val().trim();
$("table#myTable tr td").filter(function() {
if($(this).text() == search){retval=1;alert('Same item found');}
else{retval=0;}
});
The problem is that, when it finds the same item in the table cell it
shows the alertbox. But the value of my variable retval never changes. It
always shows 0. How can I solve it?

i'm trying to compare user-input to database result for example $username

passing through 2 statements without a break, and if i put a break to exit
the loop, it always check for $email == $result2 despite of not entering
any email in the field.
if( isset($_POST['username']) or isset($_POST['email']) )
{
$extract= mysql_query("SELECT username, email FROM users where
username='$username' or email='$email'");
$resultq = mysql_num_rows($extract);

ClientRequestFactory RestEasy Deprecated... Any other RestEasy alternative ?
ClientRequestFactory RestEasy Deprecated... Any other RestEasy alternative ?
I need to create rest-easy client, using de interface of the RestService
created by others... That's work good, except by just one thing...
When i update from rest-easy 2.3.5.Final to rest-easy 3.0.x, the
ClientRequestFactory class appear like @Deprecated.
The actual code is:
ClientRequestFactory crf = new
ClientRequestFactory(UriBuilder.fromUri("http://url-of-service").build());
SomeRestInterface client = crf.createProxy(SomeRestInterface.class);
client.theMethod();
Any one, now what is the alternative of rest-easy for ClientRequestFactory
at version 3.0.x?

SAML IDP and WS-Federation SP with ADFS 2.0
SAML IDP and WS-Federation SP with ADFS 2.0
I am very confused about my current ADFS setup. I have an identity
provider that issues a SAML 2.0 token to ADFS 2.0 in an IDP-Initiated
scenario. ADFS translates the token into WS-Federation, and forwards it on
to a claims aware (WIF) web application. The web application, however
doesn't recognize the user has having authenticated and redirects back to
Home Realm discovery. I've used SAML Tracer in Firefox and I can see the
SAML assertions going in and the WS-Federation claims in the parameters
being sent to the web application. Is there a step I am missing? I set up
custom claim rules to translate the SAML assertion into a WS-Federation
claim (e.g. http://schemas.xmlsoap.org/ws/2005/05/identity/claims/name) If
I switch the SP application to a SAML 2 web app, then everything works
fine.

How can I simplify my "equation" to switch between 3 and 5?
How can I simplify my "equation" to switch between 3 and 5?
It is easy to "switch" between 0 and 1 in the following way:
int i = 0;
i = (++i) % 2; // i = 1
i = (++i) % 2; // i = 0
Similarly, I found that it is possible to "switch" between 3 and 5:
int i = 3;
i = (((i * 2) - 1) % 3) + 3; // i = 5
i = (((i * 2) - 1) % 3) + 3; // i = 3
Whereas this feels cumbersome, I am searching for a more concise way to do
it. Can it be simplified? If so, how? I am actually using this for
something, by the way.

How can I print the contents of an ArrayList in a specific way, in Java?
For example:
System.out.println("A B");
System.out.println("100 100");
System.out.println("200 200");
System.out.println("300 300");
How can I do this with an ArrayList?
I write the array list like this:
ArrayList mathChoices = new ArrayList(3);
mathChoices.add("100");
mathChoices.add("200");
mathChoices.add("300");
ArrayList historyChoices = new ArrayList(3);
historyChoices.add("100");
historyChoices.add("200");
historyChoices.add("300");
And it prints out like this:
Math History
[100, 200, 300] [100, 200, 300]
I want to print out "MATH" and then "HISTORY" with vertical columns of
100,200,300 under each word. It is supposed to be like the questions in
the game show Jeopardy.

Can I restore closed tabs after quitting Chrome?
Can I restore closed tabs after quitting Chrome?
I closed Chrome by accident. Now all the tabs I had open are presumably
gone. I don't want to risk anything by starting Chrome now before asking
for help. I fear that they will be permanently lost (overwritten files) if
I do that. I know from past experience with Firefox that restoring tabs
and browser sessions can be a tricky business.
What can I do at this point? Is there a file or something I need to copy
or rename? I know about the Ctrl+Shift+T command. But I normally use this
while browsing. Will this work AFTER closing Chrome?

Customising up Button in android
Customising up Button in android
I want to customize the up button, I am using appcompat library for my
actionbar. I don't want the default up button which android provides.
Because I am using actionbar that has produced by style generator. So that
up button looks pale with the color of actionbar that I selected. Can
someone please suggest me how to achieve it? I have searched lot but
couldn't find.
I believe it is possible. Because googleplay displays the actionbar with
up button in different color in the apps section.

Anyway to have Audio output come through 2 headsets?
Anyway to have Audio output come through 2 headsets?
So I have a pretty unique sound setup for my YouTube recording... I have
Virtual Audio Cable installed with 3 cables (PC Audio, Skype and an
Output), I don't use the Audio Repeaters, instead I use windows' own
"Listen to this device" which makes it 10x better as there is no delay in
the output...
To explain what I've done:
PC Audio
Skype Audio
Output
I use dxtory to record my PC gameplay, I then record 3 audio streams, 1 is
my microphone, 1 is (1) and the other is (2)... This is so I can remove
white noise from streams (1) and (2).
Both (1) and (2) are heard through (3) which is then "listened" through my
headphones via the "Listen to this device"... Sometimes I have a second
person in the room doing a dual commentary, and it is too much hassle to
change the cables... Is there any way, without using the Audio Repeaters
(they give me a tonne of static noise and choppiness) to output to both my
headsets, if it makes it easier, they are both the Microsoft LifeChat
LX-3000.

Showing 4 planes in the 4D space are in a same 3D hyperplane
Showing 4 planes in the 4D space are in a same 3D hyperplane
Given four 2D planes in the 4D space, how can I specify if they lie on a
3D hyperplane or not. Assume $\langle x_i, y_i, z_i, w_i \rangle$ for
$i=1,\cdots,4$ be the normal vectors of the planes. Is that enough to show
that they are not linearly independent, i.e., the following determinant is
zero?
$$ \begin{vmatrix} x_1& y_1& z_1& w_1 \\ x_2& y_2& z_2& w_2 \\ x_3& y_3&
z_3& w_3 \\ x_4& y_4& z_4& w_4 \end{vmatrix} $$
What about more than 4 dimensions? If we want to show that in $n$
dimensional space, $n$ hyperplanes of dimension $n-2$ lie on a hyperplane
of dimension $n-1$, is that enough to show that the normal vectors of the

I have two questions. First, should I use the adjective "open" or the

MySQL subtract two count columns
MySQL subtract two count columns
I have a table like this:
client msg_type msg_body
------ -------- --------
123 typeA success
123 typeB success
456 typeA success
456 typeB failure
123 typeA success
123 typeA success
etc.
I would like output like this:
client diff
------ ----
123 2
456 1
where diff is the count of typeA:success messages - typeB:success
messages. I can get the count of the typeA success using something like:
select client, count(*) from mytable where msg_type="typeA" and
msg_body="success"
However, I can't figure out how to put another count in there (for typeB)
and also subtract. I tried something like:
select client, count(*) from mytable where msg_type="typeA" and
msg_body="success" - count(*) from mytable where msg_type="typeB" and
msg_body="success"
But of course it didn't work, or I wouldn't be asking here. :) Any advice?

Regex to match blank line and comments in a file
Regex to match blank line and comments in a file
How do I ignore comments or blank/empty lines in a file when reading? I
thought /^[\s#]*$/ would do the job but it didn't:
irb(main):180:0> open(inFile, 'r').each { |ln| puts ln if ln !~ /^[\s#]*$/ }
....
....
# and ..... ThIs Is A cOmMeNt .....
....
....
=> #<File:/tmp/running-instances.txt>
irb(main):181:0>
What am I missing here? Any help would be highly appreciated. Cheers!!
PS.
I can do the separately in two steps though:
open(inFile, 'r').each { |ln| next if ln =~ /^\s*$/; puts ln if ln !~
/#[^#]*$/ }

Fancybox lightbox image group. Load images
Fancybox lightbox image group. Load images
I have an issue: I have some search output with different results. Each
result item has own image, where i call Fancybox. But when i call it -
fancybox go through all images, that are displayed at page. But i need to
load only image groups for specific result item.
Each result box has own attr data-json="{ "photos" :
["http://site.com/1.jpg", "http://site.com/2.jpg"]}" and inside of this
div - <a href="1.jpg" class='fancy'><img src="1.jpg" /></a>
How i can on calling Fancybox with certain image create small fancybox
gallery only with this images from data-json?
Thanks!

Why didnt wordpress include parameter in the save_post action refernce?
Why didnt wordpress include parameter in the save_post action refernce?
http://codex.wordpress.org/Plugin_API/Action_Reference/save_post
Why Wordpress didnt include $post and $post_ID parameter and their
function. I realise these parameter exist only when I checked the source
code, What these parameter actually do?? Don't you think that they need to
include every parameter in the action hook reference so that we can assign
action to the hook

ExtJs 4.2 example build
ExtJs 4.2 example build
I am new to ExtJs.
When practicing in eclipse do we need to include the entire library(52 MB
approx) in the appropriate location?
Is there any shorter version of this library?
Can I delete some files in the library which are not important?
What are the necessary .js files to be included for building a sample MVC
pattern, CRUD operation support application in ExtJs 4.2?

Unreliable Compiling of Very Simple Java Program in Netbeans
Unreliable Compiling of Very Simple Java Program in Netbeans
I'm a few days into learning Java and I am trying to build a simple
calculator.
When I run the code in Netbeans, perhaps 30% of the time it works great.
The window pops up with my buttons. The other 70% of the time just a blank
JFrame pops up.
In both circumstances Netbeans' Output tab is telling me BUILD SUCCESSFUL
(total time: N seconds)
My code is below - I'm certain it contains a untold numbers of problems
and errors, but specifically I'm trying to understand why the outcome of
executing it is so unreliable.
Thanks in advance,

Now I get this error when I try to launch redmine with ruby2.0 (even after

Why FullGC happens every time? I mean CMS have to work without FullGC. My

I have a realtime web application with ~100-1000 request per second. I use
CMS GC and every time when CMS starts to work FGC counter increases by 2.
Why FullGC happens every time? I mean CMS have to work without FullGC. My
JMV options:
-Xms6g
-Xmx6g
-XX:PermSize=512m
-XX:MaxPermSize=512m
-XX:+UseParNewGC
-XX:+UseConcMarkSweepGC
-XX:+UseCMSInitiatingOccupancyOnly
-XX:CMSInitiatingOccupancyFraction=70
-XX:+CMSClassUnloadingEnabled
-XX:+UseLargePages
-XX:LargePageSizeInBytes=2m
-verbose:gc
-Xloggc:gc.log
-XX:+PrintGCDetails
-XX:+PrintGCDateStamps
-Dsun.rmi.dgc.client.gcInterval=3600000
-Dsun.rmi.dgc.server.gcInterval=3600000

C copy char * to char[]
C copy char * to char[]
Hello I am trying to copy a char * pointer to a char [] array.
this is my code so far
char * string_add(char * base, char * toAdd)
{
char * string=malloc(strlen(base)+streln(toAdd)+1);
sprintf(string,"%s%s",base,toAdd);
char returnString[strlen(string)+1];
// here comes my problem:
memcpy(returnString,string,strlen(string)+1);
// want to add free(string) here
return returnString;
}
I want to use such a function to save code. I don't want to look after
every allocated memory. I also tried
memcpy(&returnString,string,strlen(string)+1);
and some variants with strcpy and strncpy. But following problem persists:
if I call the function twice like:
int main(int argc, char * argv[])
{
char * str1=string_add(argv[1],"-test1");
char * str2=string_add(argv[1],"-test2");
printf("%s, %s", str1,str2);
}
the output is like:
abc-test2, abc-test2
How can I realize this?
Thank you in advance!

Remove 'X' from vim tab bar
Remove 'X' from vim tab bar
When using multiple tabs in vim, there is a bar at the top displaying the
tabs. At the far right of that bar there is an X. This is used to close
the current tab if use of the mouse is enabled; however, I don't use the
mouse in vim, so for me it is a bit of useless cruft taking up space.
With many tabs open, vim doesn't display the whole filename in each files,
only the last few characters. Getting rid of this X -- and the small
amount of empty space that seems to be reserved next to it -- would free
up a little bit of space. I would be interested in a method to simply turn
it invisible, but the ideal answer would give me a way to remove it
entirely and free up this space.

Ruby soundcloud Gem : uninitialized constant SoundCloud (NameError)
Ruby soundcloud Gem : uninitialized constant SoundCloud (NameError)
I installed the SoundCloud ruby gem but when I tried running the example
'Print links of the 10 hottest tracks' on this page
https://github.com/soundcloud/soundcloud-ruby I kept getting an error
message "uninitialized constant SoundCloud (NameError)"
I did follow the instruction on the example, registered a client and got
my client_id (not sure how to get the access token, which is not required
in this example)
I followed the instruction on http://docs.rubygems.org/read/chapter/3 to
add require 'soundcloud' to the example code but i still keep getting the
same error message.
I am using OSX terminal.
sorry i'm new to ruby and soundcloud API so my question might be very
entry level.

Trying to make good looking comments to law in Russian
Trying to make good looking comments to law in Russian
Suppose, I have a Russian text: quotes from law and my comments. And I
want to put the comments in a such way, that:
the reader can easily distinguish comments from the text of the law
it won't distract the attention too much from the main text
Something like this:
What I achieved so far is this:
\documentclass[12pt]{article}
\usepackage[a4paper]{geometry}
\usepackage[utf8]{inputenc}
\usepackage[russian]{babel}
\usepackage[T2A]{fontenc}
\setlength{\parindent}{0cm}
\newcommand{\note}[1]{\\\hfill\begin{minipage}{\dimexpr\textwidth-0.5cm}
\begin{itemize}
\item \textbf{\textit{#1}}
\end{itemize}
\xdef\tpd{\the\prevdepth}
\end{minipage}\\
}
\begin{document}
Òåêñò òåêñò òåêñò
\note{Ìîå âàæíîå çàìå÷àíèå}
Òåêñò òåêñò òåêñò
\end{document}
Generating this:
I think, that bold italic it's too distracting.
So, I tried OpenSans font, suggested by egreg here: Why does
\usepackage[T2A]{fontenc} take over?:
\newcommand{\note}[1]{\\\hfill\begin{minipage}{\dimexpr\textwidth-0.5cm}
\begin{itemize}
\item {\fontfamily{fos}\selectfont \footnotesize #1}
\end{itemize}
\xdef\tpd{\the\prevdepth}
\end{minipage}\\
}
This is better, but when I tried to make it italic, it reverted to
computer modern:
\item {\fontfamily{fos}\selectfont \it #1}

TextBox not displayed when rendering form with Html.BeginForm
TextBox not displayed when rendering form with Html.BeginForm
I've just begun learning ASP MVC 4, and I'm working on a basic exercise,
which is a book hosting website.
I'm currently working on a controller for adding a new book to the
repository. The view for the appropriate action is strongly-typed to the
Book class as its model. Book is a very simple model consisting of title,
author and so forth.
My AddBook controller currently looks like this: (I haven't implemented
any database insertion logic on POST, yet)
public class AddBookController : Controller
{
[HttpGet]
public ActionResult AddBook()
{
return View();
}
[HttpPost]
public ActionResult AddBook(Book book)
{
return View();
}
}
My view is also very simple:
@model Bookshare.Models.Book
@{
ViewBag.Title = "AddBook";
}
Add a new book
@using (Html.BeginForm())
{
Html.TextBoxFor(model => model.Title);
Html.TextBoxFor(model => model.Author);
Html.TextBoxFor(model => model.PublishingCompany);
Html.TextBoxFor(model => model.ReleaseYear);
Html.TextBoxFor(model => model.Summary);
}
And yet, when I call this action, all I can see is the "Add a new book"
header and the submit button for the form. No text boxes whatsoever. This
also happens if I use the plain old Html.TextBox syntax. Viewing the
page's source reveals just an empty form tag.
What am I doing wrong here?

URI routing in codeigniter
URI routing in codeigniter
As the title suggests, my issue is with codeIgniter.
I have used a code in an .htaccess file to remove index.php whcih works
all OK.
But I need to go further in changing the URI:
My main controller is page(), so when a user is in my homepage, the
URL-bar shows:
www.example.com/page/
(because homepage is index page, it does not show the page name as usual
the controller suffice),
but If I go to registration page, the URL-bar shows:
www.example.com/page/register
Up to here everything is OK, but I want the codeIgniter to show my domain
without the page() when the user is in my homepage, I don't want foolish
www.example.com/page/ to appear and I think when someone is visiting index
page, the URL-bar better to be www.example.com

Optimization: Algorthm to share 5 Apples with 3 people - compute all valid permutations
Optimization: Algorthm to share 5 Apples with 3 people - compute all valid
permutations
Stuck with a problem.
Given 5 apples and 3 people, compute all possible distribution permutations.
For example:
1) Peter gets 5 Apples, Paul None, Mary None
2) Peter gets 4 Apples, Paul 1, Mary None
etc...
Peter Paul Mary
5 0 0
4 1 0
4 0 1
3 2 0
3 1 1
3 0 2
2 3 0
2 2 1
2 1 2

1 1 3
1 0 4
0 0 5
0 1 4
0 2 3
0 3 2
0 4 1
0 5 0
All 5 apples must be distributed and no more than 5 apples may be
distributed.
Is there an algorithm that will allow me to calculate all permutations,
when when the parameters change.
e.g. 7 Apples and 4 people.
Probably simple for you maths wizards?
Thanks! Harry

Java bytecode manipulation?
Java bytecode manipulation?
So, I'm writing an AV, and I'm developing hooks for a sandbox thing, and I
have a problem: I can't edit the java.lang.* files, nor can I overwrite
them with a classloader. Whenever I try to edit the bytes of a class file,
no good happens. Say, I have a copy of the source code from Runtime(with
reflection for the restricted bits), works 100% the same as the one in
java.lang, I can't modify the bytes to change all references from the lang
one to my custom one. Look at this, I compile this class, which just opens
notepad.exe:
Êþº¾...3.(......Start......java/lang/Object...<init>...()V...Code.............LineNumberTable...LocalVariableTable...this...LStart;...main...([Ljava/lang/String;)V...........java/lang/Runtime........getRuntime...()Ljava/lang/Runtime;......notepad.exe.............exec..'(Ljava/lang/String;)Ljava/lang/Process;...........java/io/IOException..

I got the text dump from HxD.
Then I replace all occurrences of java/lang/Runtime with
JavaProphet/JoustJAV/sandbox/Runtime and I get this:
Êþº¾...3.(......Start......java/lang/Object...<init>...()V...Code.............LineNumberTable...LocalVariableTable...this...LStart;...main...([Ljava/lang/String;)V...........JavaProphet/JoustJAV/sandbox/Runtime........getRuntime...()LJavaProphet/JoustJAV/sandbox/Runtime;......notepad.exe.............exec..'(Ljava/lang/String;)Ljava/lang/Process;...........java/io/IOException..

Now, if I run the first file, notepad opens, if I open the second file, I
get this error:

Now, I assume that those dots are integers or some sort of indexing for
the data in the class file, but what do I need to change to get this class
file to work? I've looked into ASM, but I didn't see a class replacement
mechanism. Suggestions, anyone?
So, I'm writing an AV, and I'm developing hooks for a sandbox thing, and I
have a problem: I can't edit the java.lang.* files, nor can I overwrite
them with a classloader. Whenever I try to edit the bytes of a class file,
no good happens. Say, I have a copy of the source code from Runtime(with
reflection for the restricted bits), works 100% the same as the one in
java.lang, I can't modify the bytes to change all references from the lang
one to my custom one. Look at this, I compile this class, which just opens
notepad.exe:
Êþº¾...3.(......Start......java/lang/Object...<init>...()V...Code.............LineNumberTable...LocalVariableTable...this...LStart;...main...([Ljava/lang/String;)V...........java/lang/Runtime........getRuntime...()Ljava/lang/Runtime;......notepad.exe.............exec..'(Ljava/lang/String;)Ljava/lang/Process;...........java/io/IOException..

I got the text dump from HxD.
Then I replace all occurrences of java/lang/Runtime with
JavaProphet/JoustJAV/sandbox/Runtime and I get this:

Can't publish on Facebook using Facebook SDK for Android
Can't publish on Facebook using Facebook SDK for Android
I'm using com.facebook.widget.UserSettingsFragment to manage login/logout:
Fragment userSettingsFragment = new UserSettingsFragment();
fragmentTransaction.replace(R.id.content_container, userSettingsFragment,
"userSettingsFragment");
Then in another Fragment I want to publish a message on Facebook. I check
the doc and wrote MyFragment shown below.
The connection with com.facebook.widget.UserSettingsFragment seems to
works (I can login/logout), but when I want to publish in MyFragment, it
seems that session.requestNewPublishPermissions(newPermissionsRequest);
does not change the Session, because onSessionStateChange is never called.
Anybody can help?
