I used ubuntu 12.04 I solved that problem by installing redis-server
redis-server installation for ubuntu 12.04
some configuration will new root permission Also listed manuals for other OS
Thanks
Use get_browser()
From Manual:
echo $_SERVER['HTTP_USER_AGENT'] . "\n\n";
$browser = get_browser(null, true);
print_r($browser);
Will return:

I think you could just use the String#length method...
http://ruby-doc.org/core-1.9.3/String.html#method-i-length
Example:
text = 'The quick brown fox jumps over the lazy dog.'
puts text.length > 25 ? 'Too many characters' : 'Accepted'
The default
keyword works for me:
mysql> insert into user_table (user_id, ip, partial_ip, source, user_edit_date, username) values
(default, '39.48.49.126', null, 'user signup page', now(), 'newUser');
---
Query OK, 1 row affected (0.00 sec)
I'm running mysql --version
5.1.66:
mysql Ver 14.14 Distrib **5.1.66**, for debian-linux-gnu (x86_64) using readline 6.1
You will have to define the functions inside your header file.
You cannot separate definition of template functions in to the source file and declarations in to header file.
When a template is used in a way that triggers its intstantation, a compiler needs to see that particular templates definition. This is the reason templates are often defined in the header file in which they are declared.
Reference:
C++03 standard, § 14.7.2.4:
The definition of a non-exported function template, a non-exported member function template, or a non-exported member function or static data member of a class template shall be present in every translation unit in which it is explicitly instantiated.
EDIT:
To clarify the discussion on the comments:
Technically, there are three ways to get around this linking problem:
.cpp
file. #include
the .cpp
file defining the template at the .cpp
file using the template. Each of them have their pros and cons,
Moving the defintions to header files may increase the code size(modern day compilers can avoid this) but will increase the compilation time for sure.
Using the explicit instantiation approach is moving back on to traditional macro like approach.Another disadvantage is that it is necessary to know which template types are needed by the program. For a simple program this is easy but for complicated program this becomes difficult to determine in advance.
While including cpp files is confusing at the same time shares the problems of both above approaches.
I find first method the easiest to follow and implement and hence advocte using it.
Every time I get a Working copy locked error I run a "Clean up". After that everything is back to normal.
On the command line you can execute svn cleanup
which also removes lock files.
Note: Perform this operation on one level up directory and that should resolve most of the times.
I know it's a little late for an answer, but I've created a polyfill for the .live() method. I've tested it in jQuery 1.11, and it seems to work pretty well. I know that we're supposed to implement the .on() method wherever possible, but in big projects, where it's not possible to convert all .live() calls to the equivalent .on() calls for whatever reason, the following might work:
if(jQuery && !jQuery.fn.live) {
jQuery.fn.live = function(evt, func) {
$('body').on(evt, this.selector, func);
}
}
Just include it after you load jQuery and before you call live().
I provide this post for both IntelliJ and Eclipse.
Eclipse:
For making unit test for your project, please follow these steps (I am using Eclipse in order to write this test):
1- Click on New -> Java Project.
2- Write down your project name and click on finish.
3- Right click on your project. Then, click on New -> Class.
4- Write down your class name and click on finish.
Then, complete the class like this:
public class Math {
int a, b;
Math(int a, int b) {
this.a = a;
this.b = b;
}
public int add() {
return a + b;
}
}
5- Click on File -> New -> JUnit Test Case.
6- Check setUp() and click on finish. SetUp() will be the place that you initialize your test.
7- Click on OK.
8- Here, I simply add 7 and 10. So, I expect the answer to be 17. Complete your test class like this:
import org.junit.Assert;
import org.junit.Before;
import org.junit.Test;
public class MathTest {
Math math;
@Before
public void setUp() throws Exception {
math = new Math(7, 10);
}
@Test
public void testAdd() {
Assert.assertEquals(17, math.add());
}
}
9- Write click on your test class in package explorer and click on Run as -> JUnit Test.
10- This is the result of the test.
IntelliJ: Note that I used IntelliJ IDEA community 2020.1 for the screenshots. Also, you need to set up your jre before these steps. I am using JDK 11.0.4.
1- Right-click on the main folder of your project-> new -> directory. You should call this 'test'. 2- Right-click on the test folder and create the proper package. I suggest creating the same packaging names as the original class. Then, you right-click on the test directory -> mark directory as -> test sources root. 3- In the right package in the test directory, you need to create a Java class (I suggest to use Test.java). 4- In the created class, type '@Test'. Then, among the options that IntelliJ gives you, select Add 'JUnitx' to classpath. 5- Write your test method in your test class. The method signature is like:
@Test
public void test<name of original method>(){
...
}
You can do your assertions like below:
Assertions.assertTrue(f.flipEquiv(node1_1, node2_1));
These are the imports that I added:
import org.junit.jupiter.api.Assertions;
import org.junit.jupiter.api.Test;
This is the test that I wrote:
You can check your methods like below:
Assertions.assertEquals(<Expected>,<actual>);
Assertions.assertTrue(<actual>);
...
For running your unit tests, right-click on the test and click on Run .
If your test passes, the result will be like below:
I hope it helps. You can see the structure of the project in GitHub https://github.com/m-vahidalizadeh/problem_solving_project.
Canvas would be a great way to do this, as @pst said above. Check out this answer for a good example:
Some code that would serve you specifically as well:
var imgd = context.getImageData(x, y, width, height);
var pix = imgd.data;
for (var i = 0, n = pix.length; i < n; i += 4) {
console.log pix[i+3]
}
This will go row by row, so you'd need to convert that into an x,y and either convert the for loop to a direct check or run a conditional inside.
Reading your question again, it looks like you want to be able to get the point that the person clicks on. This can be done pretty easily with jquery's click event. Just run the above code inside a click handler as such:
$('el').click(function(e){
console.log(e.clientX, e.clientY)
}
Those should grab your x and y values.
Simply use the Get-Content
and Set-Content
cmdlets:
Get-Content inputFile1.txt, inputFile2.txt | Set-Content joinedFile.txt
You can concatenate more than two files with this style, too.
If the source files are named similarly, you can use wildcards:
Get-Content inputFile*.txt | Set-Content joinedFile.txt
Note 1: PowerShell 5 and older versions allowed this to be done more concisely using the aliases cat
and sc
for Get-Content
and Set-Content
respectively. However, these aliases are problematic because cat
is a system command in *nix systems, and sc
is a system command in Windows systems - therefore using them is not recommended, and in fact sc
is no longer even defined as of PowerShell Core (v7). The PowerShell team recommends against using aliases in general.
Note 2: Be careful with wildcards - if you try to output to examples.txt
(or similar that matches the pattern), PowerShell will get into an infinite loop! (I just tested this.)
Note 3: Outputting to a file with >
does not preserve character encoding! This is why using Set-Content
is recommended.
For getting straight to "who is blocked/blocking" I combined/abbreviated sp_who and sp_lock into a single query which gives a nice overview of who has what object locked to what level.

Copied from: sp_WhoLock – a T-SQL stored proc combining sp_who and sp_lock...
NB the [Xclusive lock for command] column can be misleading -- it shows the current command for that spid; but the X lock could have been triggered by an earlier command in the transaction.
When you use append
, jQuery expects it to be well-formed HTML (plain text counts). append
is not like doing +=
.
You need to make the table first, then append it.
var $table = $('<table/>');
for(var i=0; i<3; i++){
$table.append( '<tr><td>' + 'result' + i + '</td></tr>' );
}
$('#here_table').append($table);
Following SierraX and Peter's suggestion about text manipulation, curly brackets {}
are used to pass a variable to a command, for instance:
Let's say you have a sposi.txt file containing the first line of a well-known Italian novel:
> sposi="somewhere/myfolder/sposi.txt"
> cat $sposi
Ouput: quel ramo del lago di como che volge a mezzogiorno
Now create two variables:
# Search the 2nd word found in the file that "sposi" variable points to
> word=$(cat $sposi | cut -d " " -f 2)
# This variable will replace the word
> new_word="filone"
Now substitute the word variable content with the one of new_word, inside sposi.txt file
> sed -i "s/${word}/${new_word}/g" $sposi
> cat $sposi
Ouput: quel filone del lago di como che volge a mezzogiorno
The word "ramo" has been replaced.
Use this: https://github.com/gilamran/JQuery-Plugin-AnyChange
It handles all the ways to change the input, including content menu (Using the mouse)
I didn't apply paging on my gridview and it extends to more than 600 records (with checkbox, buttons, etc.) and the value of 2001 didn't work. You may increase the value, say 10000 and test.
<appSettings>
<add key="aspnet:MaxHttpCollectionKeys" value="10000" />
</appSettings>
According to Html5 specs you should use -- element.options[e.selectedIndex].text
e.g. if you have select box like below :
<select id="selectbox1">
<option value="1">First</option>
<option value="2" selected="selected">Second</option>
<option value="3">Third</option>
</select>
<br/>
<button onClick="GetItemValue('selectbox1');">Get Item</button>
you can get value using following script :
<script>
function GetItemValue(q) {
var e = document.getElementById(q);
var selValue = e.options[e.selectedIndex].text ;
alert("Selected Value: "+selValue);
}
</script>
Tried and tested.
Try placing the host name (db01.mysql.vm.MyHostingServer.net
) in your windows host (C:\windows\system32\drivers\etc\host
) file along with it's IP address and port number and see if that helps.
First activate Google+ API, then you will get "Simple API access" box, from there you can get developer key as API key https://code.google.com/apis/console/?api=plus or read this: http://code.google.com/p/google-api-php-client/wiki/OAuth2
if user doesn't have any qr reader, what will happen to the application? if it crashes, may i ask user to download for example QrDroid and after that use it?
Interestingly, Google now introduced Mobile Vision APIs, they are integrated in play services itself.
In your Gradle file just add:
compile 'com.google.android.gms:play-services-vision:11.4.0'
Taken from this QR code tutorial.
UPDATE 2020:
Now QR code scanning is also a part of ML Kit, so you can bundle the model inside the app and use it by integrating the following gradle dependency:
dependencies {
// ...
// Use this dependency to bundle the model with your app
implementation 'com.google.mlkit:barcode-scanning:16.0.3'
}
Or you can use the following gradle dependency to dynamically download the models from Google Play Services:
dependencies {
// ...
// Use this dependency to use the dynamically downloaded model in Google Play Services
implementation 'com.google.android.gms:play-services-mlkit-barcode-scanning:16.1.2'
}

Seems I don't have enough rep to post a comment, so another answer will have to do.
When you unlink a node using removeChild() or by setting the innerHTML property on the parent, you also need to make sure that there is nothing else referencing it otherwise it won't actually be destroyed and will lead to a memory leak. There are lots of ways in which you could have taken a reference to the node before calling removeChild() and you have to make sure those references that have not gone out of scope are explicitly removed.
Doug Crockford writes here that event handlers are known a cause of circular references in IE and suggests removing them explicitly as follows before calling removeChild()
function purge(d) {
var a = d.attributes, i, l, n;
if (a) {
for (i = a.length - 1; i >= 0; i -= 1) {
n = a[i].name;
if (typeof d[n] === 'function') {
d[n] = null;
}
}
}
a = d.childNodes;
if (a) {
l = a.length;
for (i = 0; i < l; i += 1) {
purge(d.childNodes[i]);
}
}
}
And even if you take a lot of precautions you can still get memory leaks in IE as described by Jens-Ingo Farley here.
And finally, don't fall into the trap of thinking that Javascript delete is the answer. It seems to be suggested by many, but won't do the job. Here is a great reference on understanding delete by Kangax.
I guess I'm a bit late to the party but I have written a small function to accomplish this task. It also takes care of attributes, text content and even if multiple nodes with the same node-name are siblings.
Dislaimer: I'm not a PHP native, so please bear with simple mistakes.
function xml2js($xmlnode) {
$root = (func_num_args() > 1 ? false : true);
$jsnode = array();
if (!$root) {
if (count($xmlnode->attributes()) > 0){
$jsnode["$"] = array();
foreach($xmlnode->attributes() as $key => $value)
$jsnode["$"][$key] = (string)$value;
}
$textcontent = trim((string)$xmlnode);
if (count($textcontent) > 0)
$jsnode["_"] = $textcontent;
foreach ($xmlnode->children() as $childxmlnode) {
$childname = $childxmlnode->getName();
if (!array_key_exists($childname, $jsnode))
$jsnode[$childname] = array();
array_push($jsnode[$childname], xml2js($childxmlnode, true));
}
return $jsnode;
} else {
$nodename = $xmlnode->getName();
$jsnode[$nodename] = array();
array_push($jsnode[$nodename], xml2js($xmlnode, true));
return json_encode($jsnode);
}
}
Usage example:
$xml = simplexml_load_file("myfile.xml");
echo xml2js($xml);
Example Input (myfile.xml):
<family name="Johnson">
<child name="John" age="5">
<toy status="old">Trooper</toy>
<toy status="old">Ultrablock</toy>
<toy status="new">Bike</toy>
</child>
</family>
Example output:
{"family":[{"$":{"name":"Johnson"},"child":[{"$":{"name":"John","age":"5"},"toy":[{"$":{"status":"old"},"_":"Trooper"},{"$":{"status":"old"},"_":"Ultrablock"},{"$":{"status":"new"},"_":"Bike"}]}]}]}
Pretty printed:
{
"family" : [{
"$" : {
"name" : "Johnson"
},
"child" : [{
"$" : {
"name" : "John",
"age" : "5"
},
"toy" : [{
"$" : {
"status" : "old"
},
"_" : "Trooper"
}, {
"$" : {
"status" : "old"
},
"_" : "Ultrablock"
}, {
"$" : {
"status" : "new"
},
"_" : "Bike"
}
]
}
]
}
]
}
Quirks to keep in mind: Several tags with the same tagname can be siblings. Other solutions will most likely drop all but the last sibling. To avoid this each and every single node, even if it only has one child, is an array which hold an object for each instance of the tagname. (See multiple "" elements in example)
Even the root element, of which only one should exist in a valid XML document is stored as array with an object of the instance, just to have a consistent data structure.
To be able to distinguish between XML node content and XML attributes each objects attributes are stored in the "$" and the content in the "_" child.
Edit: I forgot to show the output for your example input data
{
"states" : [{
"state" : [{
"$" : {
"id" : "AL"
},
"name" : [{
"_" : "Alabama"
}
]
}, {
"$" : {
"id" : "AK"
},
"name" : [{
"_" : "Alaska"
}
]
}
]
}
]
}
If it is a category page,you can get id of current category by:
$category = get_category( get_query_var( 'cat' ) );
$cat_id = $category->cat_ID;
If you want to get category id of any particular category on any page, try using :
$category_id = get_cat_ID('Category Name');
elasticsearch(ES) supports both a GET or a POST request for getting the data from the ES cluster index.
When we do a GET:
http://localhost:9200/[your index name]/_search?size=[no of records you want]&q=*:*
When we do a POST:
http://localhost:9200/[your_index_name]/_search
{
"size": [your value] //default 10
"from": [your start index] //default 0
"query":
{
"match_all": {}
}
}
I would suggest to use a UI plugin with elasticsearch http://mobz.github.io/elasticsearch-head/ This will help you get a better feeling of the indices you create and also test your indices.
Here is a table that is not a SELECT * FROM
SHOW TABLES FROM `db` LIKE 'tablename'; //zero rows = not exist
Got this from a database pro, here is what I was told:
select 1 from `tablename`; //avoids a function call
select * from INFORMATION_SCHEMA.tables where schema = 'db' and table = 'table' // slow. Field names not accurate
SHOW TABLES FROM `db` LIKE 'tablename'; //zero rows = does not exist
I was also having above doubt, what worked for me is
ALTER TABLE `your_table` CHANGE `property` `property`
VARCHAR(whatever_you_want) CHARACTER SET utf8 COLLATE utf8_unicode_ci NOT NULL;
I don't understand what exactly is the problem with implementing location listening functionality in the Service. It looks pretty similar to what you do in Activity. Just define a location listener and register for location updates. You can refer to the following code as example:
Manifest file:
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<application
android:icon="@drawable/ic_launcher"
android:label="@string/app_name" >
<activity android:label="@string/app_name" android:name=".LocationCheckerActivity" >
<intent-filter >
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<service android:name=".MyService" android:process=":my_service" />
</application>
The service file:
import android.app.Service;

I tried the above solutions but the following worked on me
export JAVA_HOME=/usr/java/default
I just updated matplotlib to 1.1.0 on my system and it now allows me to save to jpg with savefig
.
To upgrade to matplotlib 1.1.0 with pip
, use this command:
pip install -U 'http://sourceforge.net/projects/matplotlib/files/matplotlib/matplotlib-1.1.0/matplotlib-1.1.0.tar.gz/download'
EDIT (to respond to comment):
pylab
is simply an aggregation of the matplotlib.pyplot and numpy namespaces (as well as a few others) jinto a single namespace.
On my system, pylab
is just this:
from matplotlib.pylab import *
import matplotlib.pylab
__doc__ = matplotlib.pylab.__doc__
You can see that pylab
is just another namespace in your matplotlib installation. Therefore, it doesn't matter whether or not you import it with pylab
or with matplotlib.pyplot
.
If you are still running into problem, then I'm guessing the macosx backend doesn't support saving plots to jpg. You could try using a different backend. See here for more information.

If you want to use SimpleDateFormat
, you could write:
private final SimpleDateFormat sdf =
new SimpleDateFormat("yyyy-MM-dd HH:mm:ss.SSS");
{ sdf.setTimeZone(TimeZone.getTimeZone("GMT")); }
private long parseTimeToMillis(final String time) throws ParseException
{ return sdf.parse("1970-01-01 " + time).getTime(); }
But a custom method would be much more efficient. SimpleDateFormat
, because of all its calendar support, time-zone support, daylight-savings-time support, and so on, is pretty slow. The slowness is worth it if you actually need some of those features, but since you don't, it might not be. (It depends how often you're calling this method, and whether efficiency is a concern for your application.)
Also, SimpleDateFormat
is non-thread-safe, which is sometimes a pain. (Without knowing anything about your application, I can't guess whether that matters.)
Personally, I'd probably write a custom method.
The quick and dirty way to check what string you need it to look at the generated .resources files.
Your .resources are generated in the resources projects obj/Debug directory. (if not right click on .resx file in solution explorer and hit 'Run Custom Tool' to generate the .resources files)
Navigate to this directory and have a look at the filenames. You should see a file ending in XYZ.resources. Copy that filename and remove the trailing .resources and that is the file you should be loading.
For example in my obj/Bin directory I have the file:
MyLocalisation.Properties.Resources.resources
If the resource files are in the same Class library/Application I would use the following C#
ResourceManager RM = new ResourceManager("MyLocalisation.Properties.Resources", Assembly.GetExecutingAssembly());
However, as it sounds like you are using the resources file from a separate Class library/Application you probably want
Assembly localisationAssembly = Assembly.Load("MyLocalisation");
ResourceManager RM = new ResourceManager("MyLocalisation.Properties.Resources", localisationAssembly);
This seems to provide the info on Windows:
1.) Open a windows command prompt.
2.) Key in: java -XshowSettings:all and hit ENTER.
3.) A lot of information will be displayed on the command window. Scroll up until you find the string: sun.arch.data.model.
4.) If it says sun.arch.data.model = 32, your VM is 32 bit. If it says sun.arch.data.model = 64, your VM is 64 bit.
I prepared my commit that I wanted to amend with an older one and was surprised to see that rebase -i complained that I have uncommitted changes. But I didn't want to make my changes again specifying edit option of the older commit. So the solution was pretty easy and straightforward:
git rebase -i <commit you want to amend>^
- notice the ^
so you see the said commit in the text editoryou will get sometihng like this:
pick 8c83e24 use substitution instead of separate subsystems file to avoid jgroups.xml and jgroups-e2.xml going out of sync
pick 799ce28 generate ec2 configuration out of subsystems-ha.xml and subsystems-full-ha.xml to avoid discrepancies
pick e23d23a fix indentation of jgroups.xml
now to combine e23d23a with 8c83e24 you can change line order and use squash like this:
pick 8c83e24 use substitution instead of separate subsystems file to avoid jgroups.xml and jgroups-e2.xml going out of sync
squash e23d23a fix indentation of jgroups.xml
pick 799ce28 generate ec2 configuration out of subsystems-ha.xml and subsystems-full-ha.xml to avoid discrepancies
write and exit the file, you will be present with an editor to merge the commit messages. Do so and save/exit the text document

Unfortunately you can't do this with out adding a little extra HTML and having one piece of CSS rely on another.
HTML
First you need to wrap your header
,footer
and #body
into a #holder
div:
<div id="holder">
<header>.....</header>
<div id="body">....</div>
<footer>....</footer>
</div>
CSS
Then set height: 100%
to html
and body
(actual body, not your #body
div) to ensure you can set minimum height as a percentage on child elements.
Now set min-height: 100%
on the #holder
div so it fills the content of the screen and use position: absolute
to sit the footer at the bottom of the #holder
div.
Unfortunately, you have to apply padding-bottom
to the #body
div that is the same height as the footer
to ensure that the footer
does not sit above any content:
html,body{
height: 100%
}
#holder{
min-height: 100%;
position:relative;
}
#body{
padding-bottom: 100px; /* height of footer */
}
footer{
height: 100px;
width:100%;
position: absolute;
left: 0;
bottom: 0;
}

Nothing to add to the semantic aspects of "final".
But I'd like to add to chris green's comment that "final" might become a very important compiler optimization technique in the not so distant future. Not only in the simple case he mentioned, but also for more complex real-world class hierarchies which can be "closed" by "final", thus allowing compilers to generate more efficient dispatching code than with the usual vtable approach.
One key disadvantage of vtables is that for any such virtual object (assuming 64-bits on a typical Intel CPU) the pointer alone eats up 25% (8 of 64 bytes) of a cache line. In the kind of applications I enjoy to write, this hurts very badly. (And from my experience it is the #1 argument against C++ from a purist performance point of view, i.e. by C programmers.)
In applications which require extreme performance, which is not so unusual for C++, this might indeed become awesome, not requiring to workaround this problem manually in C style or weird Template juggling.
This technique is known as Devirtualization. A term worth remembering. :-)
There is a great recent speech by Andrei Alexandrescu which pretty well explains how you can workaround such situations today and how "final" might be part of solving similar cases "automatically" in the future (discussed with listeners):
http://channel9.msdn.com/Events/GoingNative/2013/Writing-Quick-Code-in-Cpp-Quickly
window.location.href = "URL2"
inside a JS block on the page or in an included file; that's assuming you really want to do it on the client. Usually, the server sends the redirect via a 300-series response.
Have a look at json_encode() in PHP. You can get $.ajax to recognize this with the dataType: "json" parameter.
As Mike Nakis said, echo off
only prevents the printing of commands, not results. To hide the result of a command add >nul
to the end of the line, and to hide errors add 2>nul
. For example:
Del /Q *.tmp >nul 2>nul
Like Krister Andersson said, the reason you get an error is your variable is expanding with spaces:
set INSTALL_PATH=C:\My App\Installer
if exist %INSTALL_PATH% (
Becomes:
if exist C:\My App\Installer (
Which means:
If "C:\My" exists, run "App\Installer" with "(" as the command line argument.
You see the error because you have no folder named "App". Put quotes around the path to prevent this splitting.

I had the exact error when deleting a file. It was a Windows Service running under a Service Account which was unable to delete a .pdf document from a Shared Folder even though it had Full Control of the folder.
What worked for me was navigating to the Security tab of the Shared Folder > Advanced > Share > Add.
I then added the service account to the administrators group, applied the changes and the service account was then able to perform all operations on all files within that folder.
You can get the Parent of a control via
myControl.Parent

Try this code
ArrayList<String> list = new ArrayList<String>();
JSONArray jsonArray = (JSONArray)jsonObject;
int len = jsonArray.length();
if (jsonArray != null) {
for (int i=0;i<len;i++){
list.add(jsonArray.get(i).toString());
}
}
//Remove the element from arraylist
list.remove(position);
//Recreate JSON Array
JSONArray jsArray = new JSONArray(list);
Edit:
Using ArrayList
will add "\"
to the key and values. So, use JSONArray
itself
JSONArray list = new JSONArray();
JSONArray jsonArray = new JSONArray(jsonstring);
int len = jsonArray.length();
if (jsonArray != null) {
for (int i=0;i<len;i++)
{
//Excluding the item at position
if (i != position)
{
list.put(jsonArray.get(i));
}
}
}
An alternative is to use String.format
:
double[] arr = { 23.59004,
35.7,
3.0,
9
};
for ( double dub : arr ) {
System.out.println( String.format( "%.2f", dub ) );
}
output:
23.59
35.70
3.00
9.00
You could also use System.out.format
(same method signature), or create a java.util.Formatter
which works in the same way.
I broke my head to understand why your answers for WPA/WPA2 don't work...after hours of tries I found what you are missing:
conf.allowedAuthAlgorithms.set(WifiConfiguration.AuthAlgorithm.OPEN);
is REQUIRED for WPA networks!!!!
Now, it works :)
Below are two methods that are superior to looping. Both handle a "no-find" case.
VLOOKUP
with error-handling if the variable doesn't exist (INDEX/MATCH
may be a better route than VLOOKUP
, ie if your two columns A and B were in reverse order, or were far apart)VBAs FIND
method (matching a whole string in column A given I use the xlWhole
argument)
Sub Method1()
Dim strSearch As String
Dim strOut As String
Dim bFailed As Boolean
strSearch = "trees"
On Error Resume Next
strOut = Application.WorksheetFunction.VLookup(strSearch, Range("A:B"), 2, False)
If Err.Number <> 0 Then bFailed = True
On Error GoTo 0
If Not bFailed Then
MsgBox "corresponding value is " & vbNewLine & strOut
Else
MsgBox strSearch & " not found"
End If
End Sub
Sub Method2()
Dim rng1 As Range
Dim strSearch As String
strSearch = "trees"
Set rng1 = Range("A:A").Find(strSearch, , xlValues, xlWhole)
If Not rng1 Is Nothing Then
MsgBox "Find has matched " & strSearch & vbNewLine & "corresponding cell is " & rng1.Offset(0, 1)
Else
MsgBox strSearch & " not found"
End If
End Sub
I have a situation where I need a function from bash script which must not be executed before (e.g. by source
) and the problem with @$
is that myScript.sh is then run twice, it seems... So I've come up with the idea to get the function out with sed:
sed -n "/^func ()/,/^}/p" myScript.sh
And to execute it at the time I need it, I put it in a file and use source
:
sed -n "/^func ()/,/^}/p" myScript.sh > func.sh; source func.sh; rm func.sh

I was also trying to join my path using path.join(__dirname, 'access.log')
but it was throwing the same error.
Here is how I fixed it:
I first imported the path package and declared a variable named __dirname
, then called the resolve
path method.
In CommonJS
var path = require("path");
var __dirname = path.resolve();
In ES6+
import path from 'path';
const __dirname = path.resolve();

For those of you who hasn't seen one valid argument against use of Thread.Sleep in SCENARIO 2, there really is one - application exit be held up by the while loop (SCENARIO 1/3 is just plain stupid so not worthy of more mentioning)
Many who pretend to be in-the-know, screaming Thread.Sleep is evil failed to mentioned a single valid reason for those of us who demanded a practical reason not to use it - but here it is, thanks to Pete - Thread.Sleep is Evil (can be easily avoided with a timer/handler)
static void Main(string[] args)
{
Thread t = new Thread(new ThreadStart(ThreadFunc));
t.Start();
Console.WriteLine("Hit any key to exit.");
Console.ReadLine();
Console.WriteLine("App exiting");
return;
}
static void ThreadFunc()
{
int i=0;
try
{
while (true)
{
Console.WriteLine(Thread.CurrentThread.ThreadState.ToString() + " " + i);
Thread.Sleep(1000 * 10);
i++;
}
}
finally
{
Console.WriteLine("Exiting while loop");
}
return;
}
Another way to do this is by using the bitstring
module:
>>> from bitstring import BitArray
>>> input_str = '0xff'
>>> c = BitArray(hex=input_str)
>>> c.bin
'0b11111111'
And if you need to strip the leading 0b
:
>>> c.bin[2:]
'11111111'
The bitstring
module isn't a requirement, as jcollado's answer shows, but it has lots of performant methods for turning input into bits and manipulating them. You might find this handy (or not), for example:
>>> c.uint
255
>>> c.invert()
>>> c.bin[2:]
'00000000'
etc.
FWIW, I got this error when I was implementing core data in to an existing project. It turned out I forgot to link CoreData.h to my project. I had already added the CoreData framework to my project but solved the issue by linking to the framework in my pre-compiled header just like Apple's templates do:
#import <Availability.h>
#ifndef __IPHONE_5_0
#warning "This project uses features only available in iOS SDK 5.0 and later."
#endif
#ifdef __OBJC__

The best way using a button is
<input type= 'button' onclick='javascript:history.back();return false;' value='Back'>
The other answer didn't work for me. I had to use mongoose.disconnect();

You can use the onclick
attribute, just return false
if you don't want continue;
<script type="text/javascript">
function confirm_alert(node) {
return confirm("Please click on OK to continue.");
}
</script>
<a href="http://www.google.com" onclick="return confirm_alert(this);">Click Me</a>
Let me start out by saying that I don't recommend using the method I'm about to suggest. It's much better to use event driven development and bind events only to the elements you're interested in knowing whether or not the mouse is over with mouseover
, mouseout
, mouseenter
, mouseleave
, etc.
If you absolutely must have the ability to know which element the mouse is over, you'd need to write a function that binds the mouseover
event to everything in the DOM, and then store whatever the current element is in some variable.
You could so something like this:
window.which_element_is_the_mouse_on = (function() {
var currentElement;
$("body *").on('mouseover', function(e) {
if(e.target === e.currentTarget) {
currentElement = this;
}
});
return function() {
console.log(currentElement);
}
}());
Basically, I've created an immediate function which sets the event on all elements and stores the current element within the closure to minimize your footprint.
Here's a working demo that calls window.which_element_is_the_mouse_on
every second and logs what element the mouse is currently over to the console.
"Headers already sent" means that your PHP script already sent the HTTP headers, and as such it can't make modifications to them now.
Check that you don't send ANY content before calling session_start
. Better yet, just make session_start
the first thing you do in your PHP file (so put it at the absolute beginning, before all HTML etc).
If you are already using Alamofire for all the RESTful Api, here is what you can benifit from that.
You can add following class to your app, and call MNNetworkUtils.main.isConnected()
to get a boolean on whether its connected or not.
#import Alamofire
class MNNetworkUtils {
static let main = MNNetworkUtils()
init() {
manager = NetworkReachabilityManager(host: "google.com")
listenForReachability()
}
private let manager: NetworkReachabilityManager?
private var reachable: Bool = false
private func listenForReachability() {
self.manager?.listener = { [unowned self] status in
switch status {
case .notReachable:
self.reachable = false
case .reachable(_), .unknown:
self.reachable = true
}
}
self.manager?.startListening()
}
func isConnected() -> Bool {
return reachable
}
}
This is a singleton class. Every time, when user connect or disconnect the network, it will override self.reachable
to true/false correctly, because we start listening for the NetworkReachabilityManager
on singleton initialization.
Also in order to monitor reachability, you need to provide a host, currently I am using google.com
feel free to change to any other hosts or one of yours if needed.
Assuming that EXIT_CODE is referring to System . exit
( exit_code ) then you could do
enum ExitCode
{
NORMAL_SHUTDOWN ( 0 ) , EMERGENCY_SHUTDOWN ( 10 ) , OUT_OF_MEMORY ( 20 ) , WHATEVER ( 30 ) ;
private int value ;
ExitCode ( int value )
{
this . value = value ;
}
public void exit ( )
{
System . exit ( value ) ;
}
}
Then you can put the following at appropriate spots in your code
ExitCode . NORMAL_SHUTDOWN . exit ( ) '
Are you setting up a local 'm4
' directory? e.g.,
> aclocal -I m4 --install
Some packages come with an autogen.sh
or initgen.sh
shell script to run glibtoolize, autoheader, autoconf, automake. Here's an autogen.sh
script I use:
#! /bin/sh
case `uname` in Darwin*) glibtoolize --copy ;;
*) libtoolize --copy ;; esac
autoheader
aclocal -I m4 --install
autoconf
automake --foreign --add-missing --force-missing --copy
EDIT
You may need to add ACLOCAL_AMFLAGS = -I m4
to the top-level Makefile.am
.
Here's a somewhat cleaner way of implementing this. This makes the following changes:
.src
attributes instead of DOM elements to make it work properly.Code:
function imageCache(base, firstNum, lastNum) {
this.cache = [];
var img;
for (var i = firstNum; i <= lastnum; i++) {
img = new Image();
img.src = base + i + ".jpg";
this.cache.push(img);
}
}
imageCache.prototype.nextImage(id) {
var element = document.getElementById(id);
var targetSrc = element.src;
var cache = this.cache;
for (var i = 0; i < cache.length; i++) {
if (cache[i].src) === targetSrc) {
i++;
if (i >= cache.length) {
i = 0;
}
element.src = cache[i].src;
return;
}
}
}
// sample usage
var myCache = new imageCache('images/img/Splash_image', 1, 6);
myCache.nextImage("foo");
Some advantages of this more object oriented and DRYed approach:
P.S. If you don't know what DRY stands for, it's "Don't Repeat Yourself" and basically means that you should never have many copies of similar looking code. Anytime you have that, it should be reduced somehow to a loop or function or something that removes the need for lots of similarly looking copies of code. The end result will be smaller, usually easier to maintain and often more reusable.
class Rectangle : public Area<int> {

Solution via pure CSS as mentioned in answer marked as the best is not suitable for this situation.
The example in this topic does not have normal static href attribute, it is calling of JS only, so it will not do anything without JS.
So it is good to switch on pointer with JS only. So, solution
onMouseOver="this.style.cursor='pointer'"
as mentioned above (but I can not comment there) is the best one in this case. (But yes, generaly, for normal links not demanding JS, it is better to work with pure CSS without JS.)
I have slightly improved answer, which handles extended CSS definitions like:
background-image: url(http://d36xtkk24g8jdx.cloudfront.net/bluebar/359de8f/images/shared/noise-1.png), -webkit-linear-gradient(top, rgb(81, 127, 164), rgb(48, 96, 136))
JavaScript code:
var bg = $("div").css("background-image")
bg = bg.replace(/.*\s?url\([\'\"]?/, '').replace(/[\'\"]?\).*/, '')
Result:
"http://d36xtkk24g8jdx.cloudfront.net/bluebar/359de8f/images/shared/noise-1.png"
I had the same problem and I fixed it with:
<div id="container" style="width: 100%; height: 100%; position:absolute"></div>
The chart fits perfect to the browser even if I resize it. You can change the percentage according to your needs.
I think you can use the overload of Regex.Replace to specify the maximum number of times to replace...
var regex = new Regex(Regex.Escape("o"));
var newText = regex.Replace("Hello World", "Foo", 1);
You can enforce VM arguments for a JAR
file with the following code:

public JVMArgumentEnforcer(String argument)
{
this.argument = argument;

java.lang.management.ManagementFactory.getOperatingSystemMXBean();
return bean.getTotalPhysicalMemorySize();
}
public static boolean isUsing64BitJavaInstallation()
{
String bitVersion = System.getProperty("sun.arch.data.model");
return bitVersion.equals("64");
}
private boolean hasTargetArgument()
{
RuntimeMXBean runtimeMXBean = ManagementFactory.getRuntimeMXBean();
List<String> inputArguments = runtimeMXBean.getInputArguments();
return inputArguments.contains(argument);
}
public void forceArgument() throws Exception
{
if (!hasTargetArgument())
{
// This won't work from IDEs
if (JARUtilities.isRunningFromJARFile())
{
// Supply the desired argument
restartApplication();
} else
{
throw new IllegalStateException("Please supply the VM argument with your IDE: " + argument);
}
}
}
private void restartApplication() throws Exception
{
String javaBinary = getJavaBinaryPath();
ArrayList<String> command = new ArrayList<>();
command.add(javaBinary);
command.add("-jar");
command.add(argument);
String currentJARFilePath = JARUtilities.getCurrentJARFilePath();
command.add(currentJARFilePath);
ProcessBuilder processBuilder = new ProcessBuilder(command);
processBuilder.start();
// Kill the current process
System.exit(0);
}
private String getJavaBinaryPath()
{
return System.getProperty("java.home")
+ File.separator + "bin"
+ File.separator + "java";
}
public static class JARUtilities
{
static boolean isRunningFromJARFile() throws URISyntaxException
{
File currentJarFile = getCurrentJARFile();
return currentJarFile.getName().endsWith(".jar");
}
static String getCurrentJARFilePath() throws URISyntaxException
{
File currentJarFile = getCurrentJARFile();
return currentJarFile.getPath();
}
private static File getCurrentJARFile() throws URISyntaxException
{
return new File(JVMArgumentEnforcer.class.getProtectionDomain().getCodeSource().getLocation().toURI());
}
}
}
It is used as follows:
JVMArgumentEnforcer jvmArgumentEnforcer = new JVMArgumentEnforcer("-Duser.language=pt-BR"); // For example
jvmArgumentEnforcer.forceArgument();
Set the step
attribute to 1
:
<input type="number" step="1" />
This seems a bit buggy in Chrome right now so it might not be the best solution at the moment.
A better solution is to use the pattern
attribute, that uses a regular expression to match the input:
<input type="text" pattern="\d*" />
\d
is the regular expression for a number, *
means that it accepts more than one of them.

I had the same issue, and CTRL+L worked for me on Windows 10.
When this problem comes up with multiprocessing
a simple solution is to switch from Pool
to ThreadPool
. This can be done with no change of code other than the import-
from multiprocessing.pool import ThreadPool as Pool
This works because ThreadPool shares memory with the main thread, rather than creating a new process- this means that pickling is not required.
The downside to this method is that python isn't the greatest language with handling threads- it uses something called the Global Interpreter Lock to stay thread safe, which can slow down some use cases here. However, if you're primarily interacting with other systems (running HTTP commands, talking with a database, writing to filesystems) then your code is likely not bound by CPU and won't take much of a hit. In fact I've found when writing HTTP/HTTPS benchmarks that the threaded model used here has less overhead and delays, as the overhead from creating new processes is much higher than the overhead for creating new threads.
So if you're processing a ton of stuff in python userspace this might not be the best method.
There is also a flag CV_VERSION which will print out the full version of opencv
The mail function do not guarantee the actual delivery of mail. All it do is to pass the message to external program (usually sendmail). You need a properly configured SMTP server in order for this to work. Also keep in mind it does not support SMTP authentication. You may check out the PEAR::Mail library of SwiftMailer, both of them give you more options.
You have a risk of NullPointerException
if your calculateStr()
method returns null and then you try to call a method on str.
More generally, avoid having variables with a null value. It stronger for class attributes, by the way.
getElementById will return false if the element was not found in the DOM.
var el = document.getElementById("customx");
if (el !== null && el.value === "")
{
//The element was found and the value is empty.
}
RanRag has already answered it for your specific question.
However, more generally, what you are doing with
if [[ "$string" =~ ^hello ]]
is a regex match. To do the same in Python, you would do:
import re
if re.match(r'^hello', somestring):
# do stuff
Obviously, in this case, somestring.startswith('hello')
is better.
When you'll play enough with LocalBroadcastReceiver I'll suggest you to give Green Robot's EventBus a try - you will definitely realize the difference and usefulness of it compared to LBR. Less code, customizable about receiver's thread (UI/Bg), checking receivers availability, sticky events, events could be used as data delivery etc.
The Best Way I Can Use My Project.Use hasOwnProperty
in Tricky Way!.
var arr = []; (or) arr = new Array();
var obj = {}; (or) arr = new Object();
arr.constructor.prototype.hasOwnProperty('push') //true (This is an Array)
obj.constructor.prototype.hasOwnProperty('push') // false (This is an Object)
This can be achieved using java.util.Date
. The following code will subtract 1 hour from your date.
Date date = new Date(yourdate in date format);
Date newDate = DateUtils.addHours(date, -1)
Similarly for subtracting 20 seconds from your date
newDate = DateUtils.addSeconds(date, -20)
brew help
will show you the list of commands that are available.
brew list
will show you the list of installed packages. You can also append formulae, for example brew list postgres
will tell you of files installed by postgres (providing it is indeed installed).
brew search <search term>
will list the possible packages that you can install. brew search post
will return multiple packages that are available to install that have post in their name.
brew info <package name>
will display some basic information about the package in question.
You can also search http://searchbrew.com or https://brewformulas.org (both sites do basically the same thing)

Okay, so now we see that the parentheses are clearly balanced. What else could it be? Let's check the following code snippet's error:
int main() {
delete new T();
}
This may seem like weird usage, and it is, but I really hate memory leaks. However, the output does seem useful:
In function 'int main()':
Line 2: error: expected type-specifier before 'T'
Aha! Now we're just left with the error about the parentheses. I can't find what causes that; however, I think you are forgetting to include the file that defines Rect2f
.
findstr
sometimes hangs unexpectedly when searching large files.
I haven't confirmed the exact conditions or boundary sizes. I suspect any file larger 2GB may be at risk.
I have had mixed experiences with this, so it is more than just file size. This looks like it may be a variation on FINDSTR hangs on XP and Windows 7 if redirected input does not end with LF, but as demonstrated this particular problem manifests when input is not redirected.
The following command line session (Windows 7) demonstrates how findstr
can hang when searching a 3GB file.

Note, I've verified in a hex editor that all lines are terminated with CRLF
. The only anomaly is that the file is terminated with 0x1A
due to the way copy
works. Note however, that this anomaly doesn't cause a problem on "small" files.
With additional testing I have confirmed the following:
copy
with the /b
option for binary files prevents the addition of the 0x1A
character, and findstr
doesn't hang on the 3GB file.findstr
to hang.0x1A
character doesn't cause any problems on a "small" file. (Similarly for other terminating characters.)CRLF
after 0x1A
resolves the problem. (LF
by itself would probably suffice.)type
to pipe the file into findstr
works without hanging. (This might be due to a side effect of either type
or |
that inserts an additional End Of Line.)<
also causes findstr
to hang. But this is expected; as explained in dbenham's post: "redirected input must end in LF
".Gotcha!
You have to use RegisterStartupScript
instead of RegisterClientScriptBlock

Math.Ceiling
always rounds up (towards the ceiling)
Math.Floor
always rounds down (towards to floor)
what you are after is simply
Math.Round
which rounds as per this post
I noticed that you can also get errors if you don't specify the angles correctly, even when using glm::rotate(Model, angle_in_degrees, glm::vec3(x, y, z))
you still might run into problems. The fix I found for this was specifying the type as glm::rotate(Model, (glm::mediump_float)90, glm::vec3(x, y, z))
instead of just saying glm::rotate(Model, 90, glm::vec3(x, y, z))
Or just write the second argument, the angle in radians (previously in degrees), as a float with no cast needed such as in:
glm::mat4 rotationMatrix = glm::rotate(glm::mat4(1.0f), 3.14f, glm::vec3(1.0));
You can add glm::radians() if you want to keep using degrees. And add the includes:
#include "glm/glm.hpp"
#include "glm/gtc/matrix_transform.hpp"
Necromancing.
It looks you have just as good a schema to work with as me...
Here is how to do it correctly:
In this example, the table name is dbo.T_SYS_Language_Forms, and the column name is LANG_UID
-- First, chech if the table exists...
IF 0 < (
SELECT COUNT(*) FROM INFORMATION_SCHEMA.TABLES
WHERE TABLE_TYPE = 'BASE TABLE'
AND TABLE_SCHEMA = 'dbo'
AND TABLE_NAME = 'T_SYS_Language_Forms'
)
BEGIN
-- Check for NULL values in the primary-key column
IF 0 = (SELECT COUNT(*) FROM T_SYS_Language_Forms WHERE LANG_UID IS NULL)
BEGIN
ALTER TABLE T_SYS_Language_Forms ALTER COLUMN LANG_UID uniqueidentifier NOT NULL
-- No, don't drop, FK references might already exist...
-- Drop PK if exists
-- ALTER TABLE T_SYS_Language_Forms DROP CONSTRAINT pk_constraint_name
--DECLARE @pkDropCommand nvarchar(1000)
--SET @pkDropCommand = N'ALTER TABLE T_SYS_Language_Forms DROP CONSTRAINT ' + QUOTENAME((SELECT CONSTRAINT_NAME FROM INFORMATION_SCHEMA.TABLE_CONSTRAINTS
--WHERE CONSTRAINT_TYPE = 'PRIMARY KEY'
--AND TABLE_SCHEMA = 'dbo'
--AND TABLE_NAME = 'T_SYS_Language_Forms'
----AND CONSTRAINT_NAME = 'PK_T_SYS_Language_Forms'
--))
---- PRINT @pkDropCommand
--EXECUTE(@pkDropCommand)
-- Instead do
-- EXEC sp_rename 'dbo.T_SYS_Language_Forms.PK_T_SYS_Language_Forms1234565', 'PK_T_SYS_Language_Forms';
-- Check if they keys are unique (it is very possible they might not be)
IF 1 >= (SELECT TOP 1 COUNT(*) AS cnt FROM T_SYS_Language_Forms GROUP BY LANG_UID ORDER BY cnt DESC)
BEGIN
-- If no Primary key for this table
IF 0 =
(
SELECT COUNT(*) FROM INFORMATION_SCHEMA.TABLE_CONSTRAINTS
WHERE CONSTRAINT_TYPE = 'PRIMARY KEY'
AND TABLE_SCHEMA = 'dbo'
AND TABLE_NAME = 'T_SYS_Language_Forms'
-- AND CONSTRAINT_NAME = 'PK_T_SYS_Language_Forms'
)
ALTER TABLE T_SYS_Language_Forms ADD CONSTRAINT PK_T_SYS_Language_Forms PRIMARY KEY CLUSTERED (LANG_UID ASC)
;
-- Adding foreign key
IF 0 = (SELECT COUNT(*) FROM INFORMATION_SCHEMA.REFERENTIAL_CONSTRAINTS WHERE CONSTRAINT_NAME = 'FK_T_ZO_SYS_Language_Forms_T_SYS_Language_Forms')
ALTER TABLE T_ZO_SYS_Language_Forms WITH NOCHECK ADD CONSTRAINT FK_T_ZO_SYS_Language_Forms_T_SYS_Language_Forms FOREIGN KEY(ZOLANG_LANG_UID) REFERENCES T_SYS_Language_Forms(LANG_UID);
END -- End uniqueness check
ELSE
PRINT 'FSCK, this column has duplicate keys, and can thus not be changed to primary key...'
END -- End NULL check
ELSE
PRINT 'FSCK, need to figure out how to update NULL value(s)...'
END
A common case for simply setting -fpermissive and not sweating it exists: the thoroughly-tested and working third-party library that won't compile on newer compiler versions without -fpermissive. These libraries exist, and are very likely not the application developer's problem to solve, nor in the developer's schedule budget to do it.
Set -fpermissive and move on in that case.
Try running the following query:
repair table <table_name>;
I had the same issue and it solved me the problem.
This is an ES6 version
let date = new Date()
let newDate = new Date(date.setDate(date.getDate()-30))
console.log(newDate.getMonth()+1 + '/' + newDate.getDate() + '/' + newDate.getFullYear() )
If you are running a script, instead of a statement, you can increase this by selecting Tools/Preferences/Worksheet and increasing "Max Rows to print in a script". The default is 5000, you can change it to any size.
If you don't have any fancy gem action, but do have JSON, this CLI line will work on a hash:
puts JSON.pretty_generate(my_hash).gsub(":", " =>")
#=>
{
:key1 => "value1",
:key2 => "value2",
:key3 => "value3"
}
Your calculation is likely the culprit. Try using:
bmi = weight / Math.pow(height / 100.0, 2.0);
Because both height
and 100
are integers, you were likely getting the wrong answer when dividing. However, 100.0
is a double. I suggest you make weight
a double as well. Also, the ^
operator is not for powers. Use the Math.pow()
method instead.
I'd rather use static widths and if you'd like your page to resize depending on screen size, you can have a look at media queries.
Or, you can set a min-width on elements like header, navigation, content etc.
To me, the correct way of doing it would be the ones listed. Either ajax
or ajaxSetup
. If you really want to use get
and not use ajaxSetup
then you could create your own parameter and give it the value of the the current date/time.
I would however question your motives in not using one of the other methods.
