For example: conda install -c conda-forge spacy
On Mac OS X El Capitan I had to run these two commands to fix this error:
xcode-select --install
pip install lxml
Which ended up installing lxml-3.5.0
When you run the xcode-select command you may have to sign a EULA (so have an X-Term handy for the UI if you're doing this on a headless machine).
For me that have Visual Studio 2015 this works:
Search this in the start menu: Developer Command Prompt for VS2015
and run the program in the search result.
You can now execute your command in it, for example: cl /?
A couple of tips:
My problem was a combination of previously stated: I have set the compiler version to 15 instead of 14 and when corrected, I had to delete the cache.
I also started the Visual Studio command prompt as an administrator and from there I ran the cmake-gui.exe
Then everything worked as it was supposed to.
Get someone with access to the root account on that server to run sudo apt-get install build-essential
. If you don't know who has root access, contact the support team for your shared hosting and ask them.
Edit: If you aren't allowed access to root, you aren't ever going to get it working. You'll have to change hosting provider I'm afraid.
Maybe gcc is not in your path? Try finding gcc using which gcc
and add it to your path if it's not already there.
The easiest way to install PyQt is to just use the installer (Link in your answer, step #5). If you install python 3.3, the installer will add all of the PyQt5 extras to that python installation automatically. You won't need to do any compiling (none of: nmake, nmake install, python configure).
All of the build options are available for if you need a custom install (for instance, using a different version of python, where there isn't an installer provided by riverbank computing).
If you do need to compile your own version of PyQt5, the steps (as you have found) are here, but assume you have python and a compiler installed and in your path. The installed and in your path have been where you have been running into trouble it seems. I'd recommend using the installer version, but you need to install python 3.3 first.
Use the following instead:
boost::function<void (int)> f2( boost::bind( &myclass::fun2, this, _1 ) );
This forwards the first parameter passed to the function object to the function using place-holders - you have to tell Boost.Bind how to handle the parameters. With your expression it would try to interpret it as a member function taking no arguments.
See e.g. here or here for common usage patterns.
Note that VC8s cl.exe regularly crashes on Boost.Bind misuses - if in doubt use a test-case with gcc and you will probably get good hints like the template parameters Bind-internals were instantiated with if you read through the output.
As the transcript for SciPy told you, SciPy isn't really supposed to work on Win64:
Warning: Windows 64 bits support is experimental, and only available for
testing. You are advised not to use it for production.
So I would suggest to install the 32-bit version of Python, and stop attempting to build SciPy yourself. If you still want to try anyway, you first need to compile BLAS and LAPACK, as PiotrLegnica says. See the transcript for the places where it was looking for compiled versions of these libraries.
Just run it without options.

Another solution is to build an associative array with date format and then reformat data.
This method is useful for date formatted in an unussual way.
An example:
mydate='01.02.12 10:20:43':
myformat='dd/mm/yy HH:MM:ss';
dtsplit=mydate.split(/[\/ .:]/);
dfsplit=myformat.split(/[\/ .:]/);
// creates assoc array for date
df = new Array();
for(dc=0;dc<6;dc++) {
df[dfsplit[dc]]=dtsplit[dc];
}
// uses assc array for standard mysql format
dstring[r] = '20'+df['yy']+'-'+df['mm']+'-'+df['dd'];
dstring[r] += ' '+df['HH']+':'+df['MM']+':'+df['ss'];
I liked fab's answer but didn't want to use a dictionary for my situation so I substituted a list of tuples.
// set up your data
public static List<Tuple<string, string>> List = new List<Tuple<string, string>>
{
new Tuple<string, string>("Item1", "Item2")
}
// bind to the combo box
comboBox.DataSource = new BindingSource(List, null);
comboBox.ValueMember = "Item1";
comboBox.DisplayMember = "Item2";
//Get selected value
string value = ((Tuple<string, string>)queryList.SelectedItem).Item1;
Your logic is slightly off. The second ||
should be &&
:
if ((!isset($action)) || ($action != "add" && $action != "delete"))
You can see why your original line fails by trying out a sample value. Let's say $action
is "delete"
. Here's how the condition reduces down step by step:
// $action == "delete"
if ((!isset($action)) || ($action != "add" || $action != "delete"))
if ((!true) || ($action != "add" || $action != "delete"))
if (false || ($action != "add" || $action != "delete"))
if ($action != "add" || $action != "delete")
if (true || $action != "delete")
if (true || false)
if (true)
Oops! The condition just succeeded and printed "error", but it was supposed to fail. In fact, if you think about it, no matter what the value of $action
is, one of the two !=
tests will return true. Switch the ||
to &&
and then the second to last line becomes if (true && false)
, which properly reduces to if (false)
.
There is a way to use ||
and have the test work, by the way. You have to negate everything else using De Morgan's law, i.e.:
if ((!isset($action)) || !($action == "add" || $action == "delete"))
You can read that in English as "if action is not (either add or remove), then".
Changing the index variable i
from within the loop is unlikely to do what you expect. You may need to use a while
loop instead, and control the incrementing of the loop variable yourself. Each time around the for
loop, i
is reassigned with the next value from range()
. So something like:
i = 2
while i < n:
if(something):
do something
else:
do something else
i = 2 # restart the loop
continue
i += 1
In my example, the continue
statement jumps back up to the top of the loop, skipping the i += 1
statement for that iteration. Otherwise, i
is incremented as you would expect (same as the for
loop).
Local storage can store up to 5mb offline data, whereas session can also store up to 5 mb data. But cookies can store only 4kb data in text format.
LOCAl and Session storage data in JSON format, thus easy to parse. But cookies data is in string format.
Go to /etc/apache2/apache2.conf
You have to edit that file (you should have root permission). Change directory text as bellow:
<Directory /var/www/>
Options Indexes FollowSymLinks
AllowOverride All
Require all granted
Now you have to restart apache.
service apache2 restart
You should check for ''
(empty string) before pushing into your array. Your array has elements that are empty strings. Then your album_text.length === 0
will work just fine.
Use procmon to define your problem.
A simple working configuration using
@TestPropertySource and properties

}
1. Installing OpenCV 2.4.3
First, get OpenCV 2.4.3 from sourceforge.net. Its a self-extracting so just double click to start the installation. Install it in a directory, say C:\
.
Wait until all files get extracted. It will create a new directory C:\opencv
which
contains OpenCV header files, libraries, code samples, etc.
Now you need to add the directory C:\opencv\build\x86\vc10\bin
to your system PATH. This directory contains OpenCV DLLs required for running your code.
Open Control Panel → System → Advanced system settings → Advanced Tab → Environment variables...
On the System Variables section, select Path (1), Edit (2), and type C:\opencv\build\x86\vc10\bin;
(3), then click Ok.
On some computers, you may need to restart your computer for the system to recognize the environment path variables.
This will completes the OpenCV 2.4.3 installation on your computer.
2. Create a new project and set up Visual C++
Open Visual C++ and select File → New → Project... → Visual C++ → Empty Project. Give a name for your project (e.g: cvtest
) and set the project location (e.g: c:\projects
).
Click Ok. Visual C++ will create an empty project.
Make sure that "Debug" is selected in the solution configuration combobox. Right-click cvtest
and select Properties → VC++ Directories.
Select Include Directories to add a new entry and type C:\opencv\build\include
.
Click Ok to close the dialog.
Back to the Property dialog, select Library Directories to add a new entry and type C:\opencv\build\x86\vc10\lib
.
Click Ok to close the dialog.
Back to the property dialog, select Linker → Input → Additional Dependencies to add new entries. On the popup dialog, type the files below:
opencv_calib3d243d.lib
opencv_contrib243d.lib
opencv_core243d.lib
opencv_features2d243d.lib
opencv_flann243d.lib
opencv_gpu243d.lib
opencv_haartraining_engined.lib
opencv_highgui243d.lib
opencv_imgproc243d.lib
opencv_legacy243d.lib
opencv_ml243d.lib
opencv_nonfree243d.lib
opencv_objdetect243d.lib
opencv_photo243d.lib
opencv_stitching243d.lib
opencv_ts243d.lib
opencv_video243d.lib
opencv_videostab243d.lib
Note that the filenames end with "d" (for "debug"). Also note that if you have installed another version of OpenCV (say 2.4.9) these filenames will end with 249d instead of 243d (opencv_core249d.lib..etc).
Click Ok to close the dialog. Click Ok on the project properties dialog to save all settings.
NOTE:
These steps will configure Visual C++ for the "Debug" solution. For "Release" solution (optional), you need to repeat adding the OpenCV directories and in Additional Dependencies section, use:
opencv_core243.lib
opencv_imgproc243.lib
...
instead of:
opencv_core243d.lib
opencv_imgproc243d.lib
...
You've done setting up Visual C++, now is the time to write the real code. Right click your project and select Add → New Item... → Visual C++ → C++ File.
Name your file (e.g: loadimg.cpp
) and click Ok. Type the code below in the editor:
#include <opencv2/highgui/highgui.hpp>
#include <iostream>
using namespace cv;
using namespace std;
int main()
{
Mat im = imread("c:/full/path/to/lena.jpg");
if (im.empty())
{
cout << "Cannot load image!" << endl;
return -1;
}
imshow("Image", im);
waitKey(0);
}
The code above will load c:\full\path\to\lena.jpg
and display the image. You can
use any image you like, just make sure the path to the image is correct.
Type F5 to compile the code, and it will display the image in a nice window.
And that is your first OpenCV program!
3. Where to go from here?
Now that your OpenCV environment is ready, what's next?
c:\opencv\samples\cpp
.Similar to Harry Johnston's answer, I loop until it works.
set dirPath=C:\temp\mytest
:removedir
if exist "%dirPath%" (
rd /s /q "%dirPath%"
goto removedir
)
In case of a 2D array (matrix), you can use:
[val, idx] = max(A, [], 2);
The idx part will contain the column number of containing the max element of each row.
If the command should work with both tabs and spaces as the delimiter I would use awk
:
awk '{print $100,$101,$102,$103,$104,$105}' myfile > outfile
As long as you just need to specify 5 fields it is imo ok to just type them, for longer ranges you can use a for
loop:
awk '{for(i=100;i<=105;i++)print $i}' myfile > outfile
If you want to use cut
, you need to use the -f
option:
cut -f100-105 myfile > outfile
If the field delimiter is different from TAB
you need to specify it using -d
:
cut -d' ' -f100-105 myfile > outfile
Check the man page for more info on the cut command.
The good semantic way would be to use a checkbox, and then style it in different ways if it is checked or not. But there are no good ways do to it. You have to add extra span, extra div, and, for a really nice look, add some javascript.
So the best solution is to use a small jQuery function and two background images for styling the two different statuses of the button. Example with an up/down effect given by borders:
$(document).ready(function() {_x000D_
$('a#button').click(function() {_x000D_
$(this).toggleClass("down");_x000D_
});_x000D_
});
_x000D_
a {_x000D_
background: #ccc;_x000D_
cursor: pointer;_x000D_
border-top: solid 2px #eaeaea;_x000D_
border-left: solid 2px #eaeaea;_x000D_
border-bottom: solid 2px #777;_x000D_
border-right: solid 2px #777;_x000D_
padding: 5px 5px;_x000D_
}_x000D_
_x000D_
a.down {_x000D_
background: #bbb;_x000D_
border-top: solid 2px #777;_x000D_
border-left: solid 2px #777;_x000D_
border-bottom: solid 2px #eaeaea;_x000D_
border-right: solid 2px #eaeaea;_x000D_
}
_x000D_
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<a id="button" title="button">Press Me</a>
_x000D_
Obviously, you can add background images that represent button up and button down, and make the background color transparent.
selectedIndex is a JavaScript Select Property. For jQuery you can use this code:
jQuery(document).ready(function($) {
$("#dropDownMenuKategorie").change(function() {
// I personally prefer using console.log(), but if you want you can still go with the alert().
console.log($(this).children('option:selected').index());
});
});
Yes,
You are trying to access an element of the list that does not exist.
MyList = ["item1", "item2"]
print MyList[0] # Will work
print MyList[1] # Will Work
print MyList[2] # Will crash.
Have you got an off-by-one error?
I needed to use element.attr('form')
instead of element.form
.
I use Firefox on Fedora 12.

Try this:

Error control operator
In case the warning is expected you can use the error control operator @
to suppress thrown messages.
$role_arr = getRole(@$response->records);
While this reduces clutter in your code you should use it with caution as it may make debugging future errors harder. An example where using @
may be useful is when creating an object from user input and running it through a validation method before using it in further logic.
Null Coalesce Operator
Another alternative is using the isset_ternary operator ??
. This allows you to avoid warnings and assign default value in a short one line fashion.
$role_arr = getRole($response->records ?? null);
In Android you can create shared buffer between C++ and Java (with directAlloc method) and manipulate it in both sides.
In Webdriver, you should use driver.switchTo().defaultContent();
to get out of a frame.
You need to get out of all the frames first, then switch into outer frame again.
// between step 4 and step 5
// remove selenium.selectFrame("relative=up");
driver.switchTo().defaultContent(); // you are now outside both frames
driver.switchTo().frame("cq-cf-frame");
// now continue step 6
driver.findElement(By.xpath("//button[text()='OK']")).click();
For the Python module import to work, you must have "src" in your path, not "gen_py/lib".
When processing an import like import gen_py.lib
, it looks for a module gen_py
, then looks for a submodule lib
.
As the module gen_py
won't be in "../gen_py/lib" (it'll be in ".."), the path you added will do nothing to help the import process.
Depending on where you're running it from, try adding the relative path to the "src" folder. Perhaps it's sys.path.append('..')
. You might also have success running the script while inside the src folder directly, via relative paths like python main/MyServer.py
For Python 2.6 and later if you are dealing with bytes then a bytearray
is the most obvious choice:
>>> str(bytearray([17, 24, 121, 1, 12, 222, 34, 76]))
'\x11\x18y\x01\x0c\xde"L'
To me this is even more direct than Alex Martelli's answer - still no string manipulation or len
call but now you don't even need to import anything!
If you have no concrete implementations of the class and the methods aren't static
whats the point of testing them? If you have a concrete class then you'll be testing those methods as part of the concrete class's public API.
I know what you are thinking "I don't want to test these methods over and over thats the reason I created the abstract class", but my counter argument to that is that the point of unit tests is to allow developers to make changes, run the tests, and analyze the results. Part of those changes could include overriding your abstract class's methods, both protected
and public
, which could result in fundamental behavioral changes. Depending on the nature of those changes it could affect how your application runs in unexpected, possibly negative ways. If you have a good unit testing suite problems arising from these types changes should be apparent at development time.
In matplotlib grey colors can be given as a string of a numerical value between 0-1.
For example c = '0.1'
Then you can convert your third variable in a value inside this range and to use it to color your points.
In the following example I used the y position of the point as the value that determines the color:
from matplotlib import pyplot as plt
x = [1, 2, 3, 4, 5, 6, 7, 8, 9]
y = [125, 32, 54, 253, 67, 87, 233, 56, 67]
color = [str(item/255.) for item in y]
plt.scatter(x, y, s=500, c=color)
plt.show()
typeof will serve the purpose I think
if(typeof foo != "undefined"){}
Open cmd and navigate to project location i.e. where you run npm install or ng serve for the project.
and then run the command - ng serve --host 10.202.32.45
where 10.202.32.45
is your IP address.
You will be able to access your page at 10.202.32.45:4200
where 4200 is your port number.
Note: If you serve your app using this command then you won't be able to access localhost:4200
Run package declaration and body separately.
DELETE FROM table WHERE edit_user IS NULL;
Anyone who is here in 2021, can use @SteeveDroz answer; but unfortunately, that is only for 1 character. So I put it into a for loop to loop through and change each character of the string.
function binary_encode($str){
$bin = "";
for($i = 0, $j = strlen($str); $i < $j; $i++) $bin .= decbin(ord($str[$i])) . " ";
$bin = substr($bin, 0, strlen($bin) - 1);
return $bin;
}
function binary_decode($bin){
$char = explode(' ', $bin);
$nstr = '';
foreach($char as $ch) $nstr .= chr(bindec($ch));
return $nstr;
}
Usage:
$bin = binary_encode("String Here");
$str = binary_decode("1010011 1110100 1110010 1101001 1101110 1100111 100000 1001000 1100101 1110010 1100101");
http://sandbox.onlinephpfunctions.com/code/2553fc9e26c5148fddbb3486091d119aa59ae464
It is also possible to split the string into a character array using fold
and then iterate over this array:
for char in `echo "??????" | fold -w1`; do
echo $char
done
Use microsoft's tool for remote commands executions: PsExec
If there isn't your bat-file on remote host, copy it first. For example:
copy D:\apache-tomcat-6.0.20\apache-tomcat-7.0.30\bin\shutdown.bat \\RemoteServerNameOrIP\d$\apache-tomcat-6.0.20\apache-tomcat-7.0.30\bin\
And then execute:
psexec \\RemoteServerNameOrIP d:\apache-tomcat-6.0.20\apache-tomcat-7.0.30\bin\shutdown.bat
Note: filepath for psexec is path to file on remote server, not your local.
I have used the following in my project. you can try too.
ajax = new XMLHttpRequest();
ajax.onreadystatechange = function () {
if (ajax.status) {
if (ajax.status == 200 && (ajax.readyState == 4)){
//To do tasks if any, when upload is completed
}
}
}
ajax.upload.addEventListener("progress", function (event) {
var percent = (event.loaded / event.total) * 100;
//**percent** variable can be used for modifying the length of your progress bar.
console.log(percent);
});
ajax.open("POST", 'your file upload link', true);
ajax.send(formData);
//ajax.send is for uploading form data.
If you use the callback URL, then the API can connect to the callback URL and send or receive some data. That means API can connect to you later (after API call).
Exact definition should be in API documentation.
In my case the contents of my cell is HTML as result of a formatter. I want the value inside anchor tag. By fetching the cell contents and then creating an element out of the html via jQuery I am able to then access the raw value by calling .text() on my newly created element.
var cellContents = grid.getCell(rowid, 'ColNameHere');
console.log($(cellContents));
//in my case logs <h3><a href="#">The Value I'm After</a></h3>
var cellRawValue = $(cellContents).text();
console.log(cellRawValue); //outputs "The Value I'm After!"
my answer is based on @LLQ answer, but since in my case my cellContents isn't an input I needed to use .text()
instead of .val()
to access the raw value so I thought I'd post this in case anyone else is looking for a way to access the raw value of a formatted jqGrid cell.
This is a Pythonic way to do it:
import httplib
import yaml
c = httplib.HTTPConnection(address)
c.request('GET', url_path)
r = c.getresponse()
# get the date into a datetime object
lmd = r.getheader('last-modified')
if lmd != None:
cur_data = { url: datetime.strptime(lmd, '%a, %d %b %Y %H:%M:%S %Z') }
else:
print "Hmmm, no last-modified data was returned from the URL."
print "Returned header:"
print yaml.dump(dict(r.getheaders()), default_flow_style=False)
The rest of the script includes an example of archiving a page and checking for changes against the new version, and alerting someone by email.
As @Houcem Berrayana say
If you would like to use n>24
then you can use the code like:
Date dateBefore = new Date((d.getTime() - n * 24 * 3600 * 1000) - n * 24 * 3600 * 1000);
Suppose you want to find last 30 days date, then you'd use:
Date dateBefore = new Date((d.getTime() - 24 * 24 * 3600 * 1000) - 6 * 24 * 3600 * 1000);
When passing a struct to another function, it would usually be better to do as Donnell suggested above and pass it by reference instead.
A very good reason for this is that it makes things easier if you want to make changes that will be reflected when you return to the function that created the instance of it.
Here is an example of the simplest way to do this:
#include <stdio.h>
typedef struct student {
int age;
} student;
void addStudent(student *s) {
/* Here we can use the arrow operator (->) to dereference
the pointer and access any of it's members: */
s->age = 10;
}
int main(void) {
student aStudent = {0}; /* create an instance of the student struct */
addStudent(&aStudent); /* pass a pointer to the instance */
printf("%d", aStudent.age);
return 0;
}
In this example, the argument for the addStudent()
function is a pointer to an instance of a student
struct - student *s
. In main()
, we create an instance of the student
struct and then pass a reference to it to our addStudent()
function using the reference operator (&
).
In the addStudent()
function we can make use of the arrow operator (->
) to dereference the pointer, and access any of it's members (functionally equivalent to: (*s).age
).
Any changes that we make in the addStudent()
function will be reflected when we return to main()
, because the pointer gave us a reference to where in the memory the instance of the student
struct is being stored. This is illustrated by the printf()
, which will output "10" in this example.
Had you not passed a reference, you would actually be working with a copy of the struct you passed in to the function, meaning that any changes would not be reflected when you return to main
- unless you implemented a way of passing the new version of the struct back to main or something along those lines!
Although pointers may seem off-putting at first, once you get your head around how they work and why they are so handy they become second nature, and you wonder how you ever coped without them!
type C:\temp\test.bat>C:\temp\test.log
Yes, all these are possible when you have the direct access to the servers. But what if you have only access to the server from a web / application server? Well, the situation was this with us a long back and the solution was SQL Server Export to CSV.
On Windows when you are using PowerShell you have to enclose all parameters with quotes.

In my understanding according to Python glossary, when you create a instance of objects that are hashable, an unchangeable value is also calculated according to the members or values of the instance. For example, that value could then be used as a key in a dict as below:
>>> tuple_a = (1,2,3)
>>> tuple_a.__hash__()
2528502973977326415
>>> tuple_b = (2,3,4)
>>> tuple_b.__hash__()
3789705017596477050
>>> tuple_c = (1,2,3)
>>> tuple_c.__hash__()
2528502973977326415
>>> id(a) == id(c) # a and c same object?
False
>>> a.__hash__() == c.__hash__() # a and c same value?
True
>>> dict_a = {}
>>> dict_a[tuple_a] = 'hiahia'
>>> dict_a[tuple_c]
'hiahia'
we can find that the hash value of tuple_a and tuple_c are the same since they have the same members. When we use tuple_a as the key in dict_a, we can find that the value for dict_a[tuple_c] is the same, which means that, when they are used as the key in a dict, they return the same value because the hash values are the same. For those objects that are not hashable, the method hash is defined as None:
>>> type(dict.__hash__)
<class 'NoneType'>
I guess this hash value is calculated upon the initialization of the instance, not in a dynamic way, that's why only immutable objects are hashable. Hope this helps.
You can iterate through the array or you can convert it to a String
and use indexOf
.
if (new String(charArray).indexOf('q') < 0) {
break;
}
Creating a new String
is a bit wasteful, but it's probably the tersest code. You can also write a method to imitate the effect without incurring the overhead.
Dim
and Private
work the same, though the common convention is to use Private
at the module level, and Dim
at the Sub/Function level. Public
and Global
are nearly identical in their function, however Global
can only be used in standard modules, whereas Public
can be used in all contexts (modules, classes, controls, forms etc.) Global
comes from older versions of VB and was likely kept for backwards compatibility, but has been wholly superseded by Public
.
Note for ES2+
Starting with ES 1.5.3 the delete-by-query API is deprecated, and is completely removed since ES 2.0
Instead of the API, the Delete By Query is now a plugin.
In order to use the Delete By Query plugin you must install the plugin on all nodes of the cluster:
sudo bin/plugin install delete-by-query
All of the nodes must be restarted after the installation.
The usage of the plugin is the same as the old API. You don't need to change anything in your queries - this plugin will just make them work.
*For complete information regarding WHY the API was removed you can read more here.
var $table = $('#myTable2');
$table.bootstrapTable('destroy');
Worked for me
Try this method:
set t=20;
select *
from myTable
where age > '${hiveconf:t}';
it works well on my platform.
You can use AudioStream this way as well:
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.IOException;
import java.io.InputStream;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JPanel;
import sun.audio.AudioPlayer;
import sun.audio.AudioStream;
public class AudioWizz extends JPanel implements ActionListener {
private static final long serialVersionUID = 1L; //you like your cereal and the program likes their "serial"
static AudioWizz a;
static JButton playBuddon;
static JFrame frame;
public static void main(String arguments[]){
frame= new JFrame("AudioWizz");
frame.setSize(300,300);
frame.setVisible(true);
a= new AudioWizz();
playBuddon= new JButton("PUSH ME");
playBuddon.setBounds(10,10,80,30);
playBuddon.addActionListener(a);
frame.add(playBuddon);
frame.add(a);
}
public void actionPerformed(ActionEvent e){ //an eventListener
if (e.getSource() == playBuddon) {
try {
InputStream in = new FileInputStream("*.wav");
AudioStream sound = new AudioStream(in);
AudioPlayer.player.start(sound);
} catch(FileNotFoundException e1) {
e1.printStackTrace();
} catch (IOException e1) {
e1.printStackTrace();
}
}
}
}
Gagravarr's answer is quite good!
But if you assume that a cell is also empty if it contains an empty String (""
), you need some additional code. This can happen, if a cell was edited and then not cleared properly (for how to clear a cell properly, see further below).
I wrote myself a helper to check if an XSSFCell
is empty (including an empty String).
/**
* Checks if the value of a given {@link XSSFCell} is empty.
*
* @param cell
* The {@link XSSFCell}.
* @return {@code true} if the {@link XSSFCell} is empty. {@code false}
* otherwise.
*/
public static boolean isCellEmpty(final XSSFCell cell) {
if (cell == null) { // use row.getCell(x, Row.CREATE_NULL_AS_BLANK) to avoid null cells
return true;
}
if (cell.getCellType() == Cell.CELL_TYPE_BLANK) {
return true;
}
if (cell.getCellType() == Cell.CELL_TYPE_STRING && cell.getStringCellValue().trim().isEmpty()) {
return true;
}
return false;
}
Pay attention for newer POI Version
They first changed getCellType()
to getCellTypeEnum()
as of Version 3.15 Beta 3
and then moved back to getCellType()
as of Version 4.0
.
Version >= 3.15 Beta 3
:
CellType.BLANK
and CellType.STRING
instead of Cell.CELL_TYPE_BLANK
and Cell.CELL_TYPE_STRING
Version >= 3.15 Beta 3
&& Version < 4.0
Cell.getCellTypeEnum()
instead of Cell.getCellType()
But better double check yourself, because they planned to change it back in future releases.
This JUnit test shows the case in which the additional empty check is needed.
Scenario: the content of a cell is changed within a Java program. Later on, in the same Java program, the cell is checked for emptiness. The test will fail if the isCellEmpty(XSSFCell cell)
function doesn't check for empty Strings.
@Test
public void testIsCellEmpty_CellHasEmptyString_ReturnTrue() {
// Arrange
XSSFCell cell = new XSSFWorkbook().createSheet().createRow(0).createCell(0);
boolean expectedValue = true;
boolean actualValue;
// Act
cell.setCellValue("foo");
cell.setCellValue("bar");
cell.setCellValue(" ");
actualValue = isCellEmpty(cell);
// Assert
Assert.assertEquals(expectedValue, actualValue);
}
Just in case if someone wants to know, how to clear the content of a cell properly. There are two ways to archive that (I would recommend way 1).
// way 1
public static void clearCell(final XSSFCell cell) {
cell.setCellType(Cell.CELL_TYPE_BLANK);
}
// way 2
public static void clearCell(final XSSFCell cell) {
String nullString = null;
cell.setCellValue(nullString);
}
Why way 1? Explicit is better than implicit (thanks, Python)
Way 1: sets the cell type explicitly back to blank
.
Way 2: sets the cell type implicitly back to blank
due to a side effect when setting a cell value to a null
String.
Regards winklerrr
I'd like to shed a little bit more light on the interplay of iter
, __iter__
and __getitem__
and what happens behind the curtains. Armed with that knowledge, you will be able to understand why the best you can do is
try:
iter(maybe_iterable)
print('iteration will probably work')
except TypeError:
print('not iterable')
I will list the facts first and then follow up with a quick reminder of what happens when you employ a for
loop in python, followed by a discussion to illustrate the facts.
You can get an iterator from any object o
by calling iter(o)
if at least one of the following conditions holds true:
a) o
has an __iter__
method which returns an iterator object. An iterator is any object with an __iter__
and a __next__
(Python 2: next
) method.
b) o
has a __getitem__
method.
Checking for an instance of Iterable
or Sequence
, or checking for the
attribute __iter__
is not enough.
If an object o
implements only __getitem__
, but not __iter__
, iter(o)
will construct
an iterator that tries to fetch items from o
by integer index, starting at index 0. The iterator will catch any IndexError
(but no other errors) that is raised and then raises StopIteration
itself.
In the most general sense, there's no way to check whether the iterator returned by iter
is sane other than to try it out.
If an object o
implements __iter__
, the iter
function will make sure
that the object returned by __iter__
is an iterator. There is no sanity check
if an object only implements __getitem__
.
__iter__
wins. If an object o
implements both __iter__
and __getitem__
, iter(o)
will call __iter__
.
If you want to make your own objects iterable, always implement the __iter__
method.
for
loopsIn order to follow along, you need an understanding of what happens when you employ a for
loop in Python. Feel free to skip right to the next section if you already know.
When you use for item in o
for some iterable object o
, Python calls iter(o)
and expects an iterator object as the return value. An iterator is any object which implements a __next__
(or next
in Python 2) method and an __iter__
method.
By convention, the __iter__
method of an iterator should return the object itself (i.e. return self
). Python then calls next
on the iterator until StopIteration
is raised. All of this happens implicitly, but the following demonstration makes it visible:
import random
class DemoIterable(object):
def __iter__(self):
print('__iter__ called')
return DemoIterator()
class DemoIterator(object):
def __iter__(self):
return self
def __next__(self):
print('__next__ called')
r = random.randint(1, 10)
if r == 5:
print('raising StopIteration')
raise StopIteration
return r
Iteration over a DemoIterable
:
>>> di = DemoIterable()
>>> for x in di:
... print(x)
...
__iter__ called
__next__ called
9
__next__ called
8
__next__ called
10
__next__ called
3
__next__ called
10
__next__ called
raising StopIteration
On point 1 and 2: getting an iterator and unreliable checks
Consider the following class:
class BasicIterable(object):
def __getitem__(self, item):
if item == 3:
raise IndexError
return item
Calling iter
with an instance of BasicIterable
will return an iterator without any problems because BasicIterable
implements __getitem__
.
>>> b = BasicIterable()
>>> iter(b)
<iterator object at 0x7f1ab216e320>
However, it is important to note that b
does not have the __iter__
attribute and is not considered an instance of Iterable
or Sequence
:
>>> from collections import Iterable, Sequence
>>> hasattr(b, '__iter__')
False
>>> isinstance(b, Iterable)
False
>>> isinstance(b, Sequence)
False
This is why Fluent Python by Luciano Ramalho recommends calling iter
and handling the potential TypeError
as the most accurate way to check whether an object is iterable. Quoting directly from the book:
As of Python 3.4, the most accurate way to check whether an object
x
is iterable is to calliter(x)
and handle aTypeError
exception if it isn’t. This is more accurate than usingisinstance(x, abc.Iterable)
, becauseiter(x)
also considers the legacy__getitem__
method, while theIterable
ABC does not.
On point 3: Iterating over objects which only provide __getitem__
, but not __iter__
Iterating over an instance of BasicIterable
works as expected: Python
constructs an iterator that tries to fetch items by index, starting at zero, until an IndexError
is raised. The demo object's __getitem__
method simply returns the item
which was supplied as the argument to __getitem__(self, item)
by the iterator returned by iter
.
>>> b = BasicIterable()
>>> it = iter(b)
>>> next(it)
0
>>> next(it)
1
>>> next(it)
2
>>> next(it)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
StopIteration
Note that the iterator raises StopIteration
when it cannot return the next item and that the IndexError
which is raised for item == 3
is handled internally. This is why looping over a BasicIterable
with a for
loop works as expected:
>>> for x in b:
... print(x)
...
0
1
2
Here's another example in order to drive home the concept of how the iterator returned by iter
tries to access items by index. WrappedDict
does not inherit from dict
, which means instances won't have an __iter__
method.
class WrappedDict(object): # note: no inheritance from dict!
def __init__(self, dic):
self._dict = dic
def __getitem__(self, item):
try:
return self._dict[item] # delegate to dict.__getitem__
except KeyError:
raise IndexError
Note that calls to __getitem__
are delegated to dict.__getitem__
for which the square bracket notation is simply a shorthand.
>>> w = WrappedDict({-1: 'not printed',
... 0: 'hi', 1: 'StackOverflow', 2: '!',
... 4: 'not printed',
... 'x': 'not printed'})
>>> for x in w:
... print(x)
...
hi
StackOverflow
!
On point 4 and 5: iter
checks for an iterator when it calls __iter__
:
When iter(o)
is called for an object o
, iter
will make sure that the return value of __iter__
, if the method is present, is an iterator. This means that the returned object
must implement __next__
(or next
in Python 2) and __iter__
. iter
cannot perform any sanity checks for objects which only
provide __getitem__
, because it has no way to check whether the items of the object are accessible by integer index.
class FailIterIterable(object):
def __iter__(self):
return object() # not an iterator
class FailGetitemIterable(object):
def __getitem__(self, item):
raise Exception
Note that constructing an iterator from FailIterIterable
instances fails immediately, while constructing an iterator from FailGetItemIterable
succeeds, but will throw an Exception on the first call to __next__
.
>>> fii = FailIterIterable()
>>> iter(fii)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: iter() returned non-iterator of type 'object'
>>>
>>> fgi = FailGetitemIterable()
>>> it = iter(fgi)
>>> next(it)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/path/iterdemo.py", line 42, in __getitem__
raise Exception
Exception
On point 6: __iter__
wins
This one is straightforward. If an object implements __iter__
and __getitem__
, iter
will call __iter__
. Consider the following class
class IterWinsDemo(object):
def __iter__(self):
return iter(['__iter__', 'wins'])
def __getitem__(self, item):
return ['__getitem__', 'wins'][item]
and the output when looping over an instance:
>>> iwd = IterWinsDemo()
>>> for x in iwd:
... print(x)
...
__iter__
wins
On point 7: your iterable classes should implement __iter__
You might ask yourself why most builtin sequences like list
implement an __iter__
method when __getitem__
would be sufficient.
class WrappedList(object): # note: no inheritance from list!
def __init__(self, lst):
self._list = lst
def __getitem__(self, item):
return self._list[item]
After all, iteration over instances of the class above, which delegates calls to __getitem__
to list.__getitem__
(using the square bracket notation), will work fine:
>>> wl = WrappedList(['A', 'B', 'C'])
>>> for x in wl:
... print(x)
...
A
B
C
The reasons your custom iterables should implement __iter__
are as follows:
__iter__
, instances will be considered iterables, and isinstance(o, collections.abc.Iterable)
will return True
.__iter__
is not an iterator, iter
will fail immediately and raise a TypeError
.__getitem__
exists for backwards compatibility reasons. Quoting again from Fluent Python:That is why any Python sequence is iterable: they all implement
__getitem__
. In fact, the standard sequences also implement__iter__
, and yours should too, because the special handling of__getitem__
exists for backward compatibility reasons and may be gone in the future (although it is not deprecated as I write this).

The answer is that java.sql.Timestamp
is a mess and should be avoided. Use java.time.LocalDateTime
instead.
So why is it a mess? From the java.sql.Timestamp
JavaDoc, a java.sql.Timestamp
is a "thin wrapper around java.util.Date
that allows the JDBC API to identify this as an SQL TIMESTAMP value". From the java.util.Date
JavaDoc, "the Date
class is intended to reflect coordinated universal time (UTC)". From the ISO SQL spec a TIMESTAMP WITHOUT TIME ZONE "is a data type that is datetime without time zone". TIMESTAMP is a short name for TIMESTAMP WITHOUT TIME ZONE. So a java.sql.Timestamp
"reflects" UTC while SQL TIMESTAMP is "without time zone".
Because java.sql.Timestamp
reflects UTC its methods apply conversions. This causes no end of confusion. From the SQL perspective it makes no sense to convert a SQL TIMESTAMP value to some other time zone as a TIMESTAMP has no time zone to convert from. What does it mean to convert 42 to Fahrenheit? It means nothing because 42 does not have temperature units. It's just a bare number. Similarly you can't convert a TIMESTAMP of 2020-07-22T10:38:00 to Americas/Los Angeles because 2020-07-22T10:30:00 is not in any time zone. It's not in UTC or GMT or anything else. It's a bare date time.
java.time.LocalDateTime
is also a bare date time. It does not have a time zone, exactly like SQL TIMESTAMP. None of its methods apply any kind of time zone conversion which makes its behavior much easier to predict and understand. So don't use java.sql.Timestamp
. Use java.time.LocalDateTime
.
LocalDateTime ldt = rs.getObject(col, LocalDateTime.class);
ps.setObject(param, ldt, JDBCType.TIMESTAMP);
PHP 5.3+ solution.
$new_time = DateTime::createFromFormat('h:i A', '01:00 PM');
$time_24 = $new_time->format('H:i:s');
Output: 13:00:00
Works great when formatting date is required. Check This Answer for details.
Inline items cannot have a width. You have to use display: block
or display:inline-block
, but the latter is not supported everywhere.
For this purpose, you can create your own function. For example:
$ echo 'mkfile() { mkdir -p "$(dirname "$1")" && touch "$1" ; }' >> ~/.bashrc
$ source ~/.bashrc
$ mkfile ./fldr1/fldr2/file.txt
Explanation:
~/.bashrc
file using the echo
command-p
flag is for creating the nested folders, such as fldr2
~/.bashrc
file with the source
commandmkfile
function to create the fileConstructors are not normal methods and they cannot be "overridden". Saying that a constructor can be overridden would imply that a superclass constructor would be visible and could be called to create an instance of a subclass. This isn't true... a subclass doesn't have any constructors by default (except a no-arg constructor if the class it extends has one). It has to explicitly declare any other constructors, and those constructors belong to it and not to its superclass, even if they take the same parameters that the superclass constructors take.
The stuff you mention about default no arg constructors is just an aspect of how constructors work and has nothing to do with overriding.

If you are OS X 10.6/iOS 4.0 or later, you're probably better off with blocks than NSPredicate. See -[NSArray indexesOfObjectsPassingTest:]
or write your own category to add a handy -select:
or -filter:
method (example).
Want somebody else to write that category, test it, etc.? Check out BlocksKit (array docs). And there are many more examples to be found by, say, searching for e.g. "nsarray block category select".
It's usually the code. Here's a simple example:
import java.util.*;
public class GarbageCollector {
public static void main(String... args) {
System.out.printf("Testing...%n");
List<Double> list = new ArrayList<Double>();
for (int outer = 0; outer < 10000; outer++) {
// list = new ArrayList<Double>(10000); // BAD
// list = new ArrayList<Double>(); // WORSE
list.clear(); // BETTER
for (int inner = 0; inner < 10000; inner++) {
list.add(Math.random());
}
if (outer % 1000 == 0) {
System.out.printf("Outer loop at %d%n", outer);
}
}
System.out.printf("Done.%n");
}
}
Using Java 1.6.0_24-b07 on a Windows 7 32 bit.
java -Xloggc:gc.log GarbageCollector
Then look at gc.log
Now granted, this is not the best test or the best design but when faced with a situation where you have no choice but implementing such a loop or when dealing with existing code that behaves badly, choosing to reuse objects instead of creating new ones can reduce the number of times the garbage collector gets in the way...
In C++11, we have decltype. There is no way in standard c++ to display exact type of variable declared using decltype. We can use boost typeindex i.e type_id_with_cvr
(cvr stands for const, volatile, reference) to print type like below.
#include <iostream>
#include <boost/type_index.hpp>
using namespace std;
using boost::typeindex::type_id_with_cvr;
int main() {
int i = 0;
const int ci = 0;
cout << "decltype(i) is " << type_id_with_cvr<decltype(i)>().pretty_name() << '\n';
cout << "decltype((i)) is " << type_id_with_cvr<decltype((i))>().pretty_name() << '\n';
cout << "decltype(ci) is " << type_id_with_cvr<decltype(ci)>().pretty_name() << '\n';
cout << "decltype((ci)) is " << type_id_with_cvr<decltype((ci))>().pretty_name() << '\n';
cout << "decltype(std::move(i)) is " << type_id_with_cvr<decltype(std::move(i))>().pretty_name() << '\n';
cout << "decltype(std::static_cast<int&&>(i)) is " << type_id_with_cvr<decltype(static_cast<int&&>(i))>().pretty_name() << '\n';
return 0;
}

View: A view is a virtual table whose contents are defined by a query. Unless indexed, a view does not exist as a stored set of data values in a database. Advantages over table are
I have now come up with an own solution to this:
1. Created a general function to extract specific attributes from arrays
The function below extract only specific attributes from an associative array, or an array of associative arrays (the last is what you get when doing $collection->toArray() in Laravel).
It can be used like this:
$data = array_extract( $collection->toArray(), ['id','url'] );
I am using the following functions:
function array_is_assoc( $array )
{
return is_array( $array ) && array_diff_key( $array, array_keys(array_keys($array)) );
}
function array_extract( $array, $attributes )
{
$data = [];
if ( array_is_assoc( $array ) )
{
foreach ( $attributes as $attribute )
{
$data[ $attribute ] = $array[ $attribute ];
}
}
else
{
foreach ( $array as $key => $values )
{
$data[ $key ] = [];
foreach ( $attributes as $attribute )
{
$data[ $key ][ $attribute ] = $values[ $attribute ];
}
}
}
return $data;
}
This solution does not focus on performance implications on looping through the collections in large datasets.
2. Implement the above via a custom collection i Laravel
Since I would like to be able to simply do $collection->extract('id','url');
on any collection object, I have implemented a custom collection class.
First I created a general Model, which extends the Eloquent model, but uses a different collection class. All you models need to extend this custom model, and not the Eloquent Model then.
<?php
namespace App\Models;
use Illuminate\Database\Eloquent\Model as EloquentModel;
use Lib\Collection;
class Model extends EloquentModel
{
public function newCollection(array $models = [])
{
return new Collection( $models );
}
}
?>
Secondly I created the following custom collection class:
<?php
namespace Lib;
use Illuminate\Support\Collection as EloquentCollection;
class Collection extends EloquentCollection
{
public function extract()
{
$attributes = func_get_args();
return array_extract( $this->toArray(), $attributes );
}
}
?>
Lastly, all models should then extend your custom model instead, like such:
<?php
namespace App\Models;
class Article extends Model
{
...
Now the functions from no. 1 above are neatly used by the collection to make the $collection->extract()
method available.
Like already said, the -cp is just for telling the jvm in the command line which class to use for the main thread and where it can find the libraries (define classpath). In -jar it expects the class-path and main-class to be defined in the jar file manifest. So other is for defining things in command line while other finding them inside the jar manifest. There is no difference in performance. You can't use them at the same time, -jar will override the -cp.
Though even if you use -cp, it will still check the manifest file. So you can define some of the class-paths in the manifest and some in the command line. This is particularly useful when you have a dependency on some 3rd party jar, which you might not provide with your build or don't want to provide (expecting it to be found already in the system where it's to be installed for example). So you can use it to provide external jars. It's location may vary between systems or it may even have a different version on different system (but having the same interfaces). This way you can build the app with other version and add the actual 3rd party dependency to class-path on the command line when running it on different systems.
NOTE: Doesn't work on newer versions of jQuery.
Since you are using jQuery please use it's seralize function to serialize data and then pass it into the data parameter of ajax call:
info[0] = 'hi';
info[1] = 'hello';
var data_to_send = $.serialize(info);
$.ajax({
type: "POST",
url: "index.php",
data: data_to_send,
success: function(msg){
$('.answer').html(msg);
}
});
@tcaswell already answered, but I was in the middle of typing my answer up, so I'll go ahead and post it...
There are a number of different ways you could do this. To begin with, matplotlib
will automatically cycle through colors. By default, it cycles through blue, green, red, cyan, magenta, yellow, black:
import matplotlib.pyplot as plt
import numpy as np
x = np.linspace(0, 1, 10)
for i in range(1, 6):
plt.plot(x, i * x + i, label='$y = {i}x + {i}$'.format(i=i))
plt.legend(loc='best')
plt.show()
If you want to control which colors matplotlib cycles through, use ax.set_color_cycle
:
import matplotlib.pyplot as plt
import numpy as np
x = np.linspace(0, 1, 10)
fig, ax = plt.subplots()
ax.set_color_cycle(['red', 'black', 'yellow'])
for i in range(1, 6):
plt.plot(x, i * x + i, label='$y = {i}x + {i}$'.format(i=i))
plt.legend(loc='best')
plt.show()
If you'd like to explicitly specify the colors that will be used, just pass it to the color
kwarg (html colors names are accepted, as are rgb tuples and hex strings):
import matplotlib.pyplot as plt
import numpy as np
x = np.linspace(0, 1, 10)
for i, color in enumerate(['red', 'black', 'blue', 'brown', 'green'], start=1):
plt.plot(x, i * x + i, color=color, label='$y = {i}x + {i}$'.format(i=i))
plt.legend(loc='best')
plt.show()
Finally, if you'd like to automatically select a specified number of colors from an existing colormap:
import matplotlib.pyplot as plt
import numpy as np
x = np.linspace(0, 1, 10)
number = 5
cmap = plt.get_cmap('gnuplot')
colors = [cmap(i) for i in np.linspace(0, 1, number)]
for i, color in enumerate(colors, start=1):
plt.plot(x, i * x + i, color=color, label='$y = {i}x + {i}$'.format(i=i))
plt.legend(loc='best')
plt.show()
Try disabling Project->Build Automatically.
As Scorpio suggested, there's a process running that's got a lock on a file somewhere.
I have a large multi-module maven project that regularly fails on clean and this resolves it for me. I re-enable Build Automatically when I'm done.
Yes, it is possible to specify your own credentials without modifying the current code. It requires a small piece of code from your part though.
Create an assembly called SomeAssembly.dll with this class :
namespace SomeNameSpace
{
public class MyProxy : IWebProxy
{
public ICredentials Credentials
{
get { return new NetworkCredential("user", "password"); }
//or get { return new NetworkCredential("user", "password","domain"); }
set { }
}
public Uri GetProxy(Uri destination)
{
return new Uri("http://my.proxy:8080");
}
public bool IsBypassed(Uri host)
{
return false;
}
}
}
Add this to your config file :
<defaultProxy enabled="true" useDefaultCredentials="false">
<module type = "SomeNameSpace.MyProxy, SomeAssembly" />
</defaultProxy>
This "injects" a new proxy in the list, and because there are no default credentials, the WebRequest class will call your code first and request your own credentials. You will need to place the assemble SomeAssembly in the bin directory of your CMS application.
This is a somehow static code, and to get all strings like the user, password and URL, you might either need to implement your own ConfigurationSection, or add some information in the AppSettings, which is far more easier.

We just have to use @
in front of the deprecated function. No need to change anything as mentioned in above posts. For example: if(!@session_is_registered("username")){ }
. Just put @
and problem is solved.
I had the same issue and below steps resolved the issue:
Delete the JRE from PROJECT> properties>java build path> libraries.
Restart the eclipse
Add the JRE again
Rebuild the project using Project>Clean and chose option to build automatically.
Please try.
About your command line:
root@debian:/# sudo iptables -A INPUT -p tcp --dport 3306 --jump ACCEPT
root@debian:/# iptables-save
You are already authenticated as root
so sudo
is redundant there.
You are missing the -j
or --jump
just before the ACCEPT
parameter (just tought that was a typo and you are inserting it correctly).
About yout question:
If you are inserting the iptables
rule correctly as you pointed it in the question, maybe the issue is related to the hypervisor (virtual machine provider) you are using.
If you provide the hypervisor name (VirtualBox, VMWare?) I can further guide you on this but here are some suggestions you can try first:
check your vmachine network settings and:
if it is set to NAT, then you won't be able to connect from your base machine to the vmachine.
if it is set to Hosted, you have to configure first its network settings, it is usually to provide them an IP in the range 192.168.56.0/24, since is the default the hypervisors use for this.
if it is set to Bridge, same as Hosted but you can configure it whenever IP range makes sense for you configuration.
Hope this helps.

Download java jdk<version>-linux-x64.tar.gz
file from https://www.oracle.com/technetwork/java/javase/downloads/index.html.
Extract this file where you want. like: /home/java
(Folder name created by user in home directory).
Now open terminal.
Set path JAVA_HOME=path
of your jdk folder(open jdk folder then right click on any folder, go to properties then copy the path using select all)
and paste here.
Like: JAVA_HOME=/home/xxxx/java/JDK1.8.0_201
Let Ubuntu know where our JDK/JRE is located.
sudo update-alternatives --install /usr/bin/java java /home/xxxx/java/jdk1.8.0_201/bin/java 20000
sudo update-alternatives --install /usr/bin/javac javac /home/xxxx/java/jdk1.8.0_201/bin/javac 20000
sudo update-alternatives --install /usr/bin/javaws javaws /home/xxxx/java/jdk1.8.0_201/bin/javaws 20000
Tell Ubuntu that our installation i.e., jdk1.8.0_05 must be the default Java.
sudo update-alternatives --set java /home/xxxx/sipTest/jdk1.8.0_201/bin/java
sudo update-alternatives --set javac /home/xxxx/java/sipTest/jdk1.8.0_201/bin/javac
sudo update-alternatives --set javaws /home/xxxxx/sipTest/jdk1.8.0_201/bin/javaws
Now try:
$ sudo update-alternatives --config java
There are 3 choices for the alternative java (providing /usr/bin/java

Parsing JSON in Swift is an excellent job for code generation. I've created a tool at http://www.guideluxe.com/JsonToSwift to do just that.
You supply a sample JSON object with a class name and the tool will generate a corresponding Swift class, as well as any needed subsidiary Swift classes, to represent the structure implied by the sample JSON. Also included are class methods used to populate Swift objects, including one that utilizes the NSJSONSerialization.JSONObjectWithData method. The necessary mappings from the NSArray and NSDictionary objects are provided.
From the generated code, you only need to supply an NSData object containing JSON that matches the sample provided to the tool.
Other than Foundation, there are no dependencies.
My work was inspired by http://json2csharp.com/, which is very handy for .NET projects.
Here's how to create an NSData object from a JSON file.
let fileUrl: NSURL = NSBundle.mainBundle().URLForResource("JsonFile", withExtension: "json")!
let jsonData: NSData = NSData(contentsOfURL: fileUrl)!
For .NET DLLs you can use ildasm
You didn't say on which event.Just use below on your event listener.Or in your page load
$('#models').empty()
Then to repopulate
$.getJSON('@Url.Action("YourAction","YourController")',function(data){
var dropdown=$('#models');
dropdown.empty();
$.each(data, function (index, item) {
dropdown.append(
$('<option>', {
value: item.valueField,
text: item.DisplayField
}, '</option>'))
}
)});
There are already nice solution has been given. The below code can help others to query over datatable and get the value of each row of the datatable for the ImagePath column.
for (int i = 0; i < dataTable.Rows.Count; i++)
{
var theUrl = dataTable.Rows[i]["ImagePath"].ToString();
}
Be sure to have both objects created in controller: @post
and @comment
for the post, eg:
@post = Post.find params[:post_id]
@comment = Comment.new(:post=>@post)
Then in view:
<%= form_for([@post, @comment]) do |f| %>
Be sure to explicitly define the array in the form_for, not just comma separated like you have above.
def updateJsonFile():
jsonFile = open("replayScript.json", "r") # Open the JSON file for reading
data = json.load(jsonFile) # Read the JSON into the buffer
jsonFile.close() # Close the JSON file
## Working with buffered content
tmp = data["location"]
data["location"] = path
data["mode"] = "replay"
## Save our changes to JSON file
jsonFile = open("replayScript.json", "w+")
jsonFile.write(json.dumps(data))
jsonFile.close()
I ran into this problem when my Java class was under src/main/kotlin
. After I moved it to src/main/java
, the problem was gone.
I managed to solve this using macros.
I started recording a macro:
Name it something useful like, "SaveAndMake".
Now just remove the Save all keybinding, and add the same keybinding to your macro!
So now, every time i save, it saves and makes a dirty compile, and jRebel now detects all changes correctly.
DECLARE @ValueTable TABLE
(
Value VARCHAR (100)
)
SELECT @sql = N'SELECT SRS_SizeSetDetails.'+@COLUMN_NAME+' FROM SRS_SizeSetDetails WHERE FSizeID = '''+@FSizeID+''' AND SRS_SizeSetID = '''+@SRS_SizeSetID+'''';
INSERT INTO @ValueTable
EXEC sp_executesql @sql;
SET @Value='';
SET @Value = (SELECT TOP 1 Value FROM @ValueTable)
DELETE FROM @ValueTable
In my case I needed to do this because I had passed a method to the thread I was waiting for and that caused the lock becuase the metod was run on the GUI thread and the thread code called that method sometimes.
Task<string> myTask = Task.Run(() => {
// Your code or method call
return "Maybe you want to return other datatype, then just change it.";
});
// Some other code maybe...
while (true)
{
myTask.Wait(10);
Application.DoEvents();
if (myTask.IsCompleted) break;
}
Most commands/programs return a 0 on success and some other value, called errorlevel
, to signal an error.
You can check for this in you batch for example by:
call <THE_COMMAND_HERE>
if %ERRORLEVEL% == 0 goto :next
echo "Errors encountered during execution. Exited with status: %errorlevel%"
goto :endofscript
:next
echo "Doing the next thing"
:endofscript
echo "Script complete"
This is not the most glamorous way but works.
(must have using System.Linq;
)
int maxValue = anArray.Max();
int maxIndex = anArray.ToList().IndexOf(maxValue);
From MSDN:
The foreach statement repeats a group of embedded statements for each element in an array or an object collection that implements the System.Collections.IEnumerable or System.Collections.Generic.IEnumerable(Of T) interface.
So, it's not necessarily Array. It could even be a lazy collection with no idea about the count of items in the collection.
Method overloading can come in handy here Like:
<code>
public class myClass
{
int add(int a, int b)
{
return (a + b);
}
String add(String a, String b)
{
return (c + d);
}
public static void main(String args[])
{
myClass ob1 = new myClass);
ob1.add(2, 3);
//will return 5
ob1.add("Hello, ", "World!");
//will return Hello, World!
}
}
This answer is a complement to @Evert's on the legend position.
My first try on @Evert's solution failed due to overlaps of the legend and the subplot's title.
In fact, the overlaps are caused by fig.tight_layout()
, which changes the subplots' layout without considering the figure legend. However, fig.tight_layout()
is necessary.
In order to avoid the overlaps, we can tell fig.tight_layout()
to leave spaces for the figure's legend by fig.tight_layout(rect=(0,0,1,0.9))
.
You can use .is(':visible')
Selects all elements that are visible.
For example:
if($('#selectDiv').is(':visible')){
Also, you can get the div which is visible by:
$('div:visible').callYourFunction();
Live example:
console.log($('#selectDiv').is(':visible'));_x000D_
console.log($('#visibleDiv').is(':visible'));
_x000D_
#selectDiv {_x000D_
display: none; _x000D_
}
_x000D_
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<div id="selectDiv"></div>_x000D_
<div id="visibleDiv"></div>
_x000D_
The problem is that you are not specifying the name of the remote: Instead of
git remote add https://github.com/username/project.git
you should use:
git remote add origin https://github.com/username/project.git
From now onwards after API 24, Uri.parse(filePath)
won't work. You need to use this
final File videoFile = new File("path to your video file");
Uri fileUri = FileProvider.getUriForFile(mContext, "{yourpackagename}.fileprovider", videoFile);
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(fileUri, "video/*");
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);//DO NOT FORGET THIS EVER
startActivity(intent);
But before using this you need to understand how file provider works. Go to official document link to understand file provider better.
try this out:
SELECT
`userName`,
`carPrice`
FROM `users`
LEFT JOIN `cars`
ON cars.belongsToUser=users.id
WHERE `id`='4'
ORDER BY `carPrice` DESC
LIMIT 1

These are exactly the same. android:onClick
was added in API level 4 to make it easier, more Javascript-web-like, and drive everything from the XML. What it does internally is add an OnClickListener
on the Button, which calls your DoIt
method.
Here is what using a android:onClick="DoIt"
does internally:
Button button= (Button) findViewById(R.id.buttonId);
button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
DoIt(v);
}
});
The only thing you trade off by using android:onClick
, as usual with XML configuration, is that it becomes a bit more difficult to add dynamic content (programatically, you could decide to add one listener or another depending on your variables). But this is easily defeated by adding your test within the DoIt
method.
I think you can use the nrows
parameter. From the docs:
nrows : int, default None
Number of rows of file to read. Useful for reading pieces of large files
which seems to work. Using one of the standard large test files (988504479 bytes, 5344499 lines):
In [1]: import pandas as pd
In [2]: time z = pd.read_csv("P00000001-ALL.csv", nrows=20)
CPU times: user 0.00 s, sys: 0.00 s, total: 0.00 s
Wall time: 0.00 s
In [3]: len(z)
Out[3]: 20
In [4]: time z = pd.read_csv("P00000001-ALL.csv")
CPU times: user 27.63 s, sys: 1.92 s, total: 29.55 s
Wall time: 30.23 s
Here's how you read a file, and then write to it (overwriting any existing data), without closing and reopening:
with open(filename, "r+") as f:
data = f.read()
f.seek(0)
f.write(output)
f.truncate()
Non of the above solutions worked for me. I used the code that exists in the documentation of NodeMailer. It looks like this:
let transporter = nodemailer.createTransport({
host: 'smtp.gmail.com',
port: 465,
secure: true,
auth: {
type: 'OAuth2',
user: '[email protected]',
serviceClient: '113600000000000000000',
privateKey: '-----BEGIN PRIVATE KEY-----\nMIIEvgIBADANBg...',
accessToken: 'ya29.Xx_XX0xxxxx-xX0X0XxXXxXxXXXxX0x',
expires: 1484314697598
}
});
In your pg_hba.conf file, I see some incorrect and confusing lines:
# fine, this allows all dbs, all users, to be trusted from 192.168.0.1/32
# not recommend because of the lax permissions
host all all 192.168.0.1/32 trust
# wrong, /128 is an invalid netmask for ipv4, this line should be removed
host all all 192.168.0.1/128 trust
# this conflicts with the first line
# it says that that the password should be md5 and not plaintext
# I think the first line should be removed
host all all 192.168.0.1/32 md5
# this is fine except is it unnecessary because of the previous line
# which allows any user and any database to connect with md5 password
host chaosLRdb postgres 192.168.0.1/32 md5
# wrong, on local lines, an IP cannot be specified
# remove the 4th column
local all all 192.168.0.1/32 trust
I suspect that if you md5'd the password, this might work if you trim the lines. To get the md5 you can use perl or the following shell script:
echo -n 'chaos123' | md5sum
> d6766c33ba6cf0bb249b37151b068f10 -
So then your connect line would like something like:
my $dbh = DBI->connect("DBI:PgPP:database=chaosLRdb;host=192.168.0.1;port=5433",
"chaosuser", "d6766c33ba6cf0bb249b37151b068f10");
For more information, here's the documentation of postgres 8.X's pg_hba.conf file.
- (IBAction)logOutButton:(id)sender
{
//show confirmation message to user
CustomAlert* alert = [[CustomAlert alloc] initWithTitle:@"Confirmation" message:@"Do you want to exit?" delegate:self cancelButtonTitle:@"Cancel" otherButtonTitles:@"OK", nil];
alert.style = AlertStyleWhite;
[alert setFontName:@"Helvetica" fontColor:[UIColor blackColor] fontShadowColor:[UIColor clearColor]];
[alert show];
}
- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{
if (buttonIndex != 0) // 0 == the cancel button
{
//home button press programmatically
UIApplication *app = [UIApplication sharedApplication];
[app performSelector:@selector(suspend)];
//wait 2 seconds while app is going background
[NSThread sleepForTimeInterval:2.0];
//exit app when app is in background
NSLog(@"exit(0)");
exit(0);
}
}
According to the standard, you should be safe with that assumption. The C++ bool
type has two values - true
and false
with corresponding values 1 and 0.
The thing to watch about for is mixing bool
expressions and variables with BOOL
expression and variables. The latter is defined as FALSE = 0
and TRUE != FALSE
, which quite often in practice means that any value different from 0 is considered TRUE
.
A lot of modern compilers will actually issue a warning for any code that implicitly tries to cast from BOOL
to bool
if the BOOL
value is different than 0 or 1.

In the latest version of Chrome (Version 50.0.2661.94 m) you can accomplish this by going to the menu and then clicking -> More Tools -> Add to Desktop. You will then want to check off "Open as Window" in the popup that appears and then click "Add". Screen shots below:
based on several answers here, i found something that worked for me and i wanted to generalize and explain what's going on.
convert:
LEFT JOIN table2 t2 ON (t2.thing = t1.thing)
to:
LEFT JOIN table2 t2 ON (t2.p_key = (SELECT MIN(t2_.p_key)
FROM table2 t2_ WHERE (t2_.thing = t1.thing) LIMIT 1))
the condition that connects t1 and t2 is moved from the ON
and into the inner query WHERE
. the MIN(primary key)
or LIMIT 1
makes sure that only 1 row is returned by the inner query.
after selecting one specific row we need to tell the ON
which row it is. that's why the ON
is comparing the primary key of the joined tabled.
you can play with the inner query (i.e. order+limit) but it must return one primary key of the desired row that will tell the ON
the exact row to join.
Update - for MySQL 5.7+
another option relevant to MySQL 5.7+ is to use ANY_VALUE
+GROUP BY
. it will select an artist name that is not necessarily the first one.
SELECT feeds.*,ANY_VALUE(feeds_artists.name) artist_name
FROM feeds
LEFT JOIN feeds_artists ON feeds.id = feeds_artists.feed_id
GROUP BY feeds.id
more info about ANY_VALUE: https://dev.mysql.com/doc/refman/5.7/en/group-by-handling.html
Just because I made this mistake every time when using the submit function.
This is the full code you need:
Add the id "yourid" to the HTML form tag.
<form id="yourid" action='XXX' name='form' method='POST' accept-charset='UTF-8' enctype='multipart/form-data'>
the jQuery code:
$('#yourid').submit(function() {
// do something
});
Mu. No correct way exists, not even one that's consistent across browsers.
This is a problem that comes from the HTTP specification (section 15.6):
Existing HTTP clients and user agents typically retain authentication information indefinitely. HTTP/1.1. does not provide a method for a server to direct clients to discard these cached credentials.
On the other hand, section 10.4.2 says:
If the request already included Authorization credentials, then the 401 response indicates that authorization has been refused for those credentials. If the 401 response contains the same challenge as the prior response, and the user agent has already attempted authentication at least once, then the user SHOULD be presented the entity that was given in the response, since that entity might include relevant diagnostic information.
In other words, you may be able to show the login box again (as @Karsten says), but the browser doesn't have to honor your request - so don't depend on this (mis)feature too much.
Also, to complete what @claudio said, when cherry-picking you can also use a merging strategy.
So you could something like this git cherry-pick --strategy=recursive -X theirs commit
or git cherry-pick --strategy=recursive -X ours commit
A PDOStatement
(which you have in $users
) is a forward-cursor. That means, once consumed (the first foreach
iteration), it won't rewind to the beginning of the resultset.
You can close the cursor after the foreach
and execute the statement again:
$users = $dbh->query($sql);
foreach ($users as $row) {
print $row["name"] . "-" . $row["sex"] ."<br/>";
}
$users->execute();
foreach ($users as $row) {
print $row["name"] . "-" . $row["sex"] ."<br/>";
}
Or you could cache using tailored CachingIterator
with a fullcache:
$users = $dbh->query($sql);
$usersCached = new CachedPDOStatement($users);
foreach ($usersCached as $row) {
print $row["name"] . "-" . $row["sex"] ."<br/>";
}
foreach ($usersCached as $row) {
print $row["name"] . "-" . $row["sex"] ."<br/>";
}
You find the CachedPDOStatement
class as a gist. The caching itertor is probably more sane than storing the resultset into an array because it still offers all properties and methods of the PDOStatement
object it has wrapped.
This is the code JConsole, and potentially jps and VisualVM uses. It utilizes classes from
sun.jvmstat.monitor.*
package, from tool.jar

mvm = monitoredHost.getMonitoredVm(new VmIdentifier(vmPid.toString()));
String mvmMainClass = MonitoredVmUtil.mainClass(mvm, true);
if (mainClass.getName().equals(mvmMainClass)) {
return vmPid;
}
} finally {

}
}
} catch (java.net.URISyntaxException e) {
throw new InternalError(e.getMessage());
} catch (MonitorException e) {
throw new InternalError(e.getMessage());
}
return null;
}
}
There are few catches:
tool.jar
is a library distributed with Oracle JDK but not JRE! tool.jar
from Maven repo; configure it with Maven is a bit trickytool.jar
probably contains platform dependent (native?) code so it is not easily
distributableUPDATE: I have just double checked that JPS uses this way, that is Jvmstat library (part of tool.jar). So there is no need to call JPS as external process, call Jvmstat library directly as my example shows. You can aslo get list of all JVMs runnin on localhost this way. See JPS source code:
You could use a look-ahead assertion:
(?!999)\d{3}
This example matches three digits other than 999
.
But if you happen not to have a regular expression implementation with this feature (see Comparison of Regular Expression Flavors), you probably have to build a regular expression with the basic features on your own.
A compatible regular expression with basic syntax only would be:
[0-8]\d\d|\d[0-8]\d|\d\d[0-8]
This does also match any three digits sequence that is not 999
.

Simple solution for vertical align middle... for me it works like a charm

li{display:inline-block; text-align:center;}
li.items_inside_li{display:inline-block; vertical-align:middle;}
I think you are not configured properly,
if you are using XAMPP then you can easily send mail from localhost.
for example you can configure C:\xampp\php\php.ini
and c:\xampp\sendmail\sendmail.ini
for gmail to send mail.
in C:\xampp\php\php.ini
find extension=php_openssl.dll
and remove the semicolon from the beginning of that line to make SSL working for gmail for localhost.
in php.ini file find [mail function]
and change
SMTP=smtp.gmail.com
smtp_port=587
sendmail_from = [email protected]
sendmail_path = "C:\xampp\sendmail\sendmail.exe -t"
(use the above send mail path only and it will work)
Now Open C:\xampp\sendmail\sendmail.ini
. Replace all the existing code in sendmail.ini with following code
[sendmail]
smtp_server=smtp.gmail.com
smtp_port=587
error_logfile=error.log
debug_logfile=debug.log
[email protected]
auth_password=my-gmail-password
[email protected]
Now you have done!! create php file with mail function and send mail from localhost.
Update
First, make sure you PHP installation has SSL support (look for an "openssl" section in the output from phpinfo()
).
You can set the following settings in your PHP.ini:
ini_set("SMTP","ssl://smtp.gmail.com");
ini_set("smtp_port","465");
You can try the following:
private void button1_Click(object sender, EventArgs e)
{
OpenFileDialog fDialog = new OpenFileDialog();
fDialog.Title = "Select file to be upload";
fDialog.Filter = "All Files|*.*";
// fDialog.Filter = "PDF Files|*.pdf";
if (fDialog.ShowDialog() == DialogResult.OK)
{
textBox1.Text = fDialog.FileName.ToString();
}
}
And this is how it works upwards
private T FindParent<T>(DependencyObject item, Type StopAt) where T : class
{
if (item is T)
{
return item as T;
}
else
{
DependencyObject _parent = VisualTreeHelper.GetParent(item);
if (_parent == null)
{
return default(T);
}
else
{
Type _type = _parent.GetType();
if (StopAt != null)
{
if ((_type.IsSubclassOf(StopAt) == true) || (_type == StopAt))
{
return null;
}
}

I know you asked about C#, but if you're willing to use any .Net language then I highly recommend Visual Basic for this exact problem. Visual Basic has a feature called XML Literals that will allow you to write code like this.
Module Module1
Sub Main()
Dim myTitle = "Hello HTML"
Dim myHTML = <html>
<head>
<title><%= myTitle %></title>
</head>
<body>
<h1>Welcome</h1>
<table>
<tr><th>ID</th><th>Name</th></tr>
<tr><td>1</td><td>CouldBeAVariable</td></tr>
</table>
</body>
</html>
Console.WriteLine(myHTML)
End Sub
End Module
This allows you to write straight HTML with expression holes in the old ASP style and makes your code super readable. Unfortunately this feature is not in C#, but you could write a single module in VB and add it as a reference to your C# project.
Writing in Visual Studio also allows proper indentation for most XML Literals and expression wholes. Indentation for the expression holes is better in VS2010.
Note The accepted is perfectly fine - but wanted to add a version4 example because they are different enough.
import React from 'react';
import { Link } from 'react-router';
export default class Nav extends React.Component {
render() {
return (
<nav className="Nav">
<div className="Nav__container">
<Link to="/" className="Nav__brand">
<img src="logo.svg" className="Nav__logo" />
</Link>
<div className="Nav__right">
<ul className="Nav__item-wrapper">
<li className="Nav__item">
<Link className="Nav__link" to="/path1">Link 1</Link>
</li>
<li className="Nav__item">
<Link className="Nav__link" to="/path2">Link 2</Link>
</li>
<li className="Nav__item">
<Link className="Nav__link" to="/path3">Link 3</Link>
</li>
</ul>
</div>
</div>
</nav>
);
}
}
import React from 'react';
import { Link, Switch, Route } from 'react-router';
import Nav from './nav';
import Page1 from './page1';
import Page2 from './page2';
import Page3 from './page3';
export default class App extends React.Component {
render() {
return (
<div className="App">
<Router>
<div>
<Nav />
<Switch>
<Route exactly component={Landing} pattern="/" />
<Route exactly component={Page1} pattern="/path1" />
<Route exactly component={Page2} pattern="/path2" />
<Route exactly component={Page3} pattern="/path3" />
<Route component={Page404} />
</Switch>
</div>
</Router>
</div>
);
}
}
Alternatively, if you want a more dynamic nav, you can look at the excellent v4 docs: https://reacttraining.com/react-router/web/example/sidebar
A few people have asked about a page without the Nav, such as a login page. I typically approach it with a wrapper Route component
import React from 'react';
import { Link, Switch, Route } from 'react-router';
import Nav from './nav';
import Page1 from './page1';
import Page2 from './page2';
import Page3 from './page3';
const NavRoute = ({exact, path, component: Component}) => (
<Route exact={exact} path={path} render={(props) => (
<div>
<Header/>
<Component {...props}/>
</div>
)}/>
)
export default class App extends React.Component {
render() {
return (
<div className="App">
<Router>
<Switch>
<NavRoute exactly component={Landing} pattern="/" />
<Route exactly component={Login} pattern="/login" />
<NavRoute exactly component={Page1} pattern="/path1" />
<NavRoute exactly component={Page2} pattern="/path2" />
<NavRoute component={Page404} />
</Switch>
</Router>
</div>
);
}
}
Using Guava's Joiner
(which in r18 internally uses StringBuilder
)
String[] arr= {"1","2","3"};
Joiner noSpaceJoiner = Joiner.on("");
noSpaceJoiner.join(arr))
Joiner
is useful because it is thread-safe and immutable and can be reused in many places without having to duplicate code. In my opinion it also is more readable.
Using Java 8's Stream
support, we can also reduce this down to a one-liner.
String concat = Stream.of(arr).collect(Collectors.joining());
Both outputs in this case are 123
Example in Swift, picturing the foundry's explanation above and the Apple's documentation:
ViewController.swift
import UIKit
protocol ViewControllerProtocol {
func dismissViewController1AndPresentViewController2()
}
class ViewController: UIViewController, ViewControllerProtocol {
@IBAction func goToViewController1BtnPressed(sender: UIButton) {
let vc1: ViewController1 = self.storyboard?.instantiateViewControllerWithIdentifier("VC1") as ViewController1
vc1.delegate = self
vc1.modalTransitionStyle = UIModalTransitionStyle.FlipHorizontal
self.presentViewController(vc1, animated: true, completion: nil)
}
func dismissViewController1AndPresentViewController2() {
self.dismissViewControllerAnimated(false, completion: { () -> Void in
let vc2: ViewController2 = self.storyboard?.instantiateViewControllerWithIdentifier("VC2") as ViewController2
self.presentViewController(vc2, animated: true, completion: nil)
})
}
}
ViewController1.swift
import UIKit
class ViewController1: UIViewController {
var delegate: protocol<ViewControllerProtocol>!
@IBAction func goToViewController2(sender: UIButton) {
self.delegate.dismissViewController1AndPresentViewController2()
}
}
ViewController2.swift

}

let vc1: ViewController1 = self.storyboard?.instantiateViewControllerWithIdentifier("VC1") as ViewController1
vc1.delegate = self
self.navigationController?.pushViewController(vc1, animated: true)
}
func popViewController1AndPushViewController2() {
self.navigationController?.popViewControllerAnimated(false)
let vc2: ViewController2 = self.storyboard?.instantiateViewControllerWithIdentifier("VC2") as ViewController2
self.navigationController?.pushViewController(vc2, animated: true)
}
}

In JavaScript, we can declare a new empty object in two ways:
var obj1 = new Object();
var obj2 = {};
I have found nothing to suggest that there is any significant difference these two with regard to how they operate behind the scenes (please correct me if i am wrong – I would love to know). However, the second method (using the object literal notation) offers a few advantages.
Consider a new object that contains the members Name and TelNo. Using the new Object() convention, we can create it like this:
var obj1 = new Object();
obj1.Name = "A Person";
obj1.TelNo = "12345";
The Expando Properties feature of JavaScript allows us to create new members this way on the fly, and we achieve what were intending. However, this way isn’t very structured or encapsulated. What if we wanted to specify the members upon creation, without having to rely on expando properties and assignment post-creation?
This is where the object literal notation can help:
var obj1 = {Name:"A Person",TelNo="12345"};
Here we have achieved the same effect in one line of code and significantly fewer characters.
A further discussion the object construction methods above can be found at: JavaScript and Object Oriented Programming (OOP).
And finally, what of the idiot who overrode Object? Did you think it wasn’t possible? Well, this JSFiddle proves otherwise. Using the object literal notation prevents us from falling foul of this buffoonery.
(From http://www.jameswiseman.com/blog/2011/01/19/jslint-messages-use-the-object-literal-notation/)
I also had a similar problem
My problem was solved by doing the following:
You should stick to the NSInteger
data types when possible. So you'd create the number like that:
NSInteger myValue = 1;
NSNumber *number = [NSNumber numberWithInteger: myValue];
Decoding works with the integerValue
method then:
NSInteger value = [number integerValue];
Try this instead:
sumall = summ + sumd + sumy
print "The sum of your numbers is", sumall
sumall = str(sumall) # add this line
sumln = (int(sumall[0])+int(sumall[1]))
print "Your lucky number is", sumln
sumall
is a number, and you can't access its digits using the subscript notation (sumall[0]
, sumall[1]
). For that to work, you'll need to transform it back to a string.
Add this in your module gradle file. Its not there in default project. Then u will surely find the APK in /build/outputs/apk/
buildTypes {
debug {
applicationIdSuffix ".debug"
}
}
find( sub[, start[, end]])
Return the lowest index in the string where substring sub is found, such that sub is contained in the range [start, end]. Optional arguments start and end are interpreted as in slice notation. Return -1 if sub is not found.
From the docs.
Try Logic Friday 1
It includes tools from the Univerity of California (Espresso and misII) and makes them usable with a GUI. You can enter boolean equations and truth tables as desired. It also features a graphical gate diagram input and output.
The minimization can be carried out two-level or multi-level. The two-level form yields a minimized sum of products. The multi-level form creates a circuit composed out of logical gates. The types of gates can be restricted by the user.
Your expression simplifies to C
.
Depends upon the version. The If
operator in VB.NET 2008 is a ternary operator (as well as a null coalescence operator). This was just introduced, prior to 2008 this was not available. Here's some more info: Visual Basic If announcement
Example:
Dim foo as String = If(bar = buz, cat, dog)
[EDIT]
Prior to 2008 it was IIf
, which worked almost identically to the If
operator described Above.
Example:
Dim foo as String = IIf(bar = buz, cat, dog)
You can directly access BODY.values
:
for (var ln = 0; ln < names.length; ln++) {
var item1 = {
"person": {
"_path": "/people/"+names[ln],
},
};
BODY.values.push(item1);
}
Nice job! I've been having the exact same problem. Adding and removing the Session module worked perfectly for me too. It didn't however bring back by HttpContext.Current.User so I tried your little trick with the FormsAuth module and sure enough, that did it.
<remove name="FormsAuthentication" />
<add name="FormsAuthentication" type="System.Web.Security.FormsAuthenticationModule"/>
New introduction 2
In the previous version of macro "SaveEmailDetails" I used this statement to find Inbox:
Set FolderTgt = CreateObject("Outlook.Application"). _
GetNamespace("MAPI").GetDefaultFolder(olFolderInbox)
I have since installed a newer version of Outlook and I have discovered that it does not use the default Inbox. For each of my email accounts, it created a separate store (named for the email address) each with its own Inbox. None of those Inboxes is the default.
This macro, outputs the name of the store holding the default Inbox to the Immediate Window:
Sub DsplUsernameOfDefaultStore()
Dim NS As Outlook.NameSpace
Dim DefaultInboxFldr As MAPIFolder
Set NS = CreateObject("Outlook.Application").GetNamespace("MAPI")
Set DefaultInboxFldr = NS.GetDefaultFolder(olFolderInbox)
Debug.Print DefaultInboxFldr.Parent.Name
End Sub
On my installation, this outputs: "Outlook Data File".
I have added an extra statement to macro "SaveEmailDetails" that shows how to access the Inbox of any store.
New introduction 1
A number of people have picked up the macro below, found it useful and have contacted me directly for further advice. Following these contacts I have made a few improvements to the macro so I have posted the revised version below. I have also added a pair of macros which together will return the MAPIFolder object for any folder with the Outlook hierarchy. These are useful if you wish to access other than a default folder.
The original text referenced one question by date which linked to an earlier question. The first question has been deleted so the link has been lost. That link was to Update excel sheet based on outlook mail (closed)
Original text
There are a surprising number of variations of the question: "How do I extract data from Outlook emails to Excel workbooks?" For example, two questions up on [outlook-vba] the same question was asked on 13 August. That question references a variation from December that I attempted to answer.
For the December question, I went overboard with a two part answer. The first part was a series of teaching macros that explored the Outlook folder structure and wrote data to text files or Excel workbooks. The second part discussed how to design the extraction process. For this question Siddarth has provided an excellent, succinct answer and then a follow-up to help with the next stage.
What the questioner of every variation appears unable to understand is that showing us what the data looks like on the screen does not tell us what the text or html body looks like. This answer is an attempt to get past that problem.
The macro below is more complicated than Siddarth’s but a lot simpler that those I included in my December answer. There is more that could be added but I think this is enough to start with.
The macro creates a new Excel workbook and outputs selected properties of every email in Inbox to create this worksheet:
Near the top of the macro there is a comment containing eight hashes (#). The statement below that comment must be changed because it identifies the folder in which the Excel workbook will be created.
All other comments containing hashes suggest amendments to adapt the macro to your requirements.
How are the emails from which data is to be extracted identified? Is it the sender, the subject, a string within the body or all of these? The comments provide some help in eliminating uninteresting emails. If I understand the question correctly, an interesting email will have Subject = "Task Completed"
.
The comments provide no help in extracting data from interesting emails but the worksheet shows both the text and html versions of the email body if they are present. My idea is that you can see what the macro will see and start designing the extraction process.
This is not shown in the screen image above but the macro outputs two versions on the text body. The first version is unchanged which means tab, carriage return, line feed are obeyed and any non-break spaces look like spaces. In the second version, I have replaced these codes with the strings [TB], [CR], [LF] and [NBSP] so they are visible. If my understanding is correct, I would expect to see the following within the second text body:
Activity[TAB]Count[CR][LF]Open[TAB]35[CR][LF]HCQA[TAB]42[CR][LF]HCQC[TAB]60[CR][LF]HAbst[TAB]50 45 5 2 2 1[CR][LF] and so on
Extracting the values from the original of this string should not be difficult.
I would try amending my macro to output the extracted values in addition to the email’s properties. Only when I have successfully achieved this change would I attempt to write the extracted data to an existing workbook. I would also move processed emails to a different folder. I have shown where these changes must be made but give no further help. I will respond to a supplementary question if you get to the point where you need this information.
Good luck.

If you want to append
text or html to span
then you can do it as below.
$('p span#add_here').append('text goes here');
append will add text to span tag at the end.
to replace entire text or html inside of span you can use .text()
or .html()
I closed Visual studio IDE and reopened it by right clicking on the Visual Studio icon and saying "Run as Administrator", Then when I ran the host , It worked!!!
You can make your code simpler and more readable like this
bad_words = ['bad', 'naughty']
with open('oldfile.txt') as oldfile, open('newfile.txt', 'w') as newfile:
for line in oldfile:
if not any(bad_word in line for bad_word in bad_words):
newfile.write(line)
using a Context Manager and any.
This worked for me. It's similar to previous answers but the path to the packages is different.
Plaform: MacOS High Sierra version 10.13.3
If the strings are not even of equal length, you can use this
def strxor(a, b): # xor two strings of different lengths
if len(a) > len(b):
return "".join([chr(ord(x) ^ ord(y)) for (x, y) in zip(a[:len(b)], b)])
else:
return "".join([chr(ord(x) ^ ord(y)) for (x, y) in zip(a, b[:len(a)])])
The syntax is wrong in this clause (and similar ones)
CASE lkey WHEN lkey > 5 THEN
lkey + 2
ELSE
lkey
END
It's either
CASE WHEN [condition] THEN [expression] ELSE [expression] END
or
CASE [expression] WHEN [value] THEN [expression] ELSE [expression] END
So in your case it would read:
CASE WHEN lkey > 5 THEN
lkey + 2
ELSE
lkey
END
Check out the documentation (The CASE expression):
2A. As far as last seven days have much less rows than whole table an index can help
2B. If you are interested only in Created_Date you can try using some group by and count, it should help with the result set size
You can use dblink to create a view that is resolved in another database. This database may be on another server.
$(document).ready(function() {

// then show div2
$('#div2').show(300);
});

I know this question has been asked years ago but still wanted to share how I usually compile multiple c++ files.
g++ -c *.cpp -o myprogram
. "myprogram"
./myprogram
that's all!!
The reason I'm using * is that what if you have 30 cpp files would you type all of them? or just use the * sign and save time :)
p.s Use this method only if you don't care about makefile.
Change the Encoding of the stream writer. It's a property.
http://msdn.microsoft.com/en-us/library/system.io.streamwriter.encoding.aspx
So:
sw.Encoding = Encoding.GetEncoding(28591);
Prior to writing to the stream.
Firstly you should test your python idle to see if you have tkinter:
import tkinter
tkinter._test()
Trying typing it, copy paste doesn't work.
So after 20 hours of trying every way that recommended on those websites figured out that you can't use "tkinter.py" or any other file name that contains "tkinter..etc.py". If you have the same problem, just change the file name.
To add to the valuable content, I would like to create this reminder on why sometimes RegEx within VBA is not ideal. Not all expressions are supported, but instead may throw an Error 5017
and may leave the author guessing (which I am a victim of myself).
Whilst we can find some sources on what is supported, it would be helpfull to know which metacharacters etc. are not supported. A more in-depth explaination can be found here. Mentioned in this source:
"Although "VBScript’s regular expression ... version 5.5 implements quite a few essential regex features that were missing in previous versions of VBScript. ... JavaScript and VBScript implement Perl-style regular expressions. However, they lack quite a number of advanced features available in Perl and other modern regular expression flavors:"
So, not supported are:
\A
, alternatively use the ^
caret to match postion before 1st char in string\Z
, alternatively use the $
dollar sign to match postion after last char in string(?<=a)b
(whilst postive LookAhead is supported)(?<!a)b
(whilst negative LookAhead is supported)\{uFFFF}
/i
(case sensitivity) or /g
(global) etc. Set these through the RegExp
object properties > RegExp.Global = True
and RegExp.IgnoreCase = True
if available.'
comments in script I already hit a wall more than once using regular expressions within VBA. Usually with LookBehind
but sometimes I even forget the modifiers. I have not experienced all these above mentioned backdrops myself but thought I would try to be extensive referring to some more in-depth information. Feel free to comment/correct/add. Big shout out to regular-expressions.info for a wealth of information.
P.S. You have mentioned regular VBA methods and functions, and I can confirm they (at least to myself) have been helpful in their own ways where RegEx would fail.

In a method of your Form or Control, you have 3 choices:
this.Invalidate(); // request a delayed Repaint by the normal MessageLoop system
this.Update(); // forces Repaint of invalidated area
this.Refresh(); // Combines Invalidate() and Update()
Normally, you would just call Invalidate()
and let the system combine that with other Screen updates. If you're in a hurry you should call Refresh()
but then you run the risk that it will be repainted several times consecutively because of other controls (especially the Parent) Invalidating.
The normal way Windows (Win32 and WinForms.Net) handles this is to wait for the MessageQueue to run empty and then process all invalidated screen areas. That is efficient because when something changes that usually cascades into other things (controls) changing as well.
The most common scenario for Update() is when you change a property (say, label1.Text, which will invalidate the Label) in a for-loop and that loop is temporarily blocking the Message-Loop. Whenever you use it, you should ask yourself if you shouldn't be using a Thread instead. But the answer is't always Yes.
Its very simple, just add the quartzCore header in your file(for that you have to add the quartz framework to your project)
and then do this
[[button layer] setCornerRadius:8.0f];
[[button layer] setMasksToBounds:YES];
[[button layer] setBorderWidth:1.0f];
you can change the float values as required.
enjoy.
Here's some typical modern code ...
self.buttonTag.layer.borderWidth = 1.0f;
self.buttonCancel.layer.borderWidth = 1.0f;
self.buttonTag.layer.borderColor = [UIColor blueColor].CGColor;
self.buttonCancel.layer.borderColor = [UIColor blueColor].CGColor;
self.buttonTag.layer.cornerRadius = 4.0f;
self.buttonCancel.layer.cornerRadius = 4.0f;
that's a similar look to segmented controls.
UPDATE for Swift:
Just do:
button.layer.cornerRadius = 8.0
button.layer.borderWidth = 1.0
button.layer.borderColor = UIColor.black.cgColor
I saw in at least one other place that people don't realize Date-Time
takes in times as well, so I figured I'd share it here since it's really short to do so:
Get-Date # Following the OP's example, let's say it's Friday, March 12, 2010 9:00:00 AM
(Get-Date '22:00').AddDays(-1) # Thursday, March 11, 2010 10:00:00 PM
It's also the shortest way to strip time information and still use other parameters of Get-Date
. For instance you can get seconds since 1970 this way (Unix timestamp):
Get-Date '0:00' -u '%s' # 1268352000
Or you can get an ISO 8601 timestamp:
Get-Date '0:00' -f 's' # 2010-03-12T00:00:00
Then again if you reverse the operands, it gives you a little more freedom with formatting with any date object:
'The sortable timestamp: {0:s}Z{1}Vs measly human format: {0:D}' -f (Get-Date '0:00'), "`r`n"
# The sortable timestamp: 2010-03-12T00:00:00Z
# Vs measly human format: Friday, March 12, 2010
However if you wanted to both format a Unix timestamp (via -u
aka -UFormat
), you'll need to do it separately. Here's an example of that:
'ISO 8601: {0:s}Z{1}Unix: {2}' -f (Get-Date '0:00'), "`r`n", (Get-Date '0:00' -u '%s')
# ISO 8601: 2010-03-12T00:00:00Z
# Unix: 1268352000
Hope this helps!

I asked recently about something similar.
If you use flags you can add an extension method to enums to make checking the contained flags easier (see post for detail)
This allows you to do:
[Flags]
public enum PossibleOptions : byte
{
None = 0,
OptionOne = 1,
OptionTwo = 2,
OptionThree = 4,
OptionFour = 8,
//combinations can be in the enum too
OptionOneAndTwo = OptionOne | OptionTwo,
OptionOneTwoAndThree = OptionOne | OptionTwo | OptionThree,
...
}
Then you can do:
PossibleOptions opt = PossibleOptions.OptionOneTwoAndThree
if( opt.IsSet( PossibleOptions.OptionOne ) ) {
//optionOne is one of those set
}
I find this easier to read than the most ways of checking the included flags.
In practice, POST works well for creating resources. The URL of the newly created resource should be returned in the Location response header. PUT should be used for updating a resource completely. Please understand that these are the best practices when designing a RESTful API. HTTP specification as such does not restrict using PUT/POST with a few restrictions for creating/updating resources. Take a look at http://techoctave.com/c7/posts/71-twitter-rest-api-dissected that summarizes the best practices.
All of these options are fine, if you have the option to re-export the data.
But if you need to use an existing SQL file, and use a specific table from it, then this perl script in the TimeSheet blog, with enable you to extract the table to a separate SQL file, and then import it.
The original link is dead, so it is a good thing that someone has put it instead of the author, Jared Cheney, on GitHub, in this link.
ER/Studio by Embarcadero is one of the costlier ones, but the hierarchical mode it present is by far the best one for understanding database models. It makes query writing the easiest task in the world.
It also is incredible with normalization, denormalization, warehousing, documentation, etc.
The downside is that it is a pretty expensive tool especially when you go multiplatform.
You can't. Variables defined inside a method are local to that method.
If you want to share variables between methods, then you'll need to specify them as member variables of the class. Alternatively, you can pass them from one method to another as arguments (this isn't always applicable).
Looks like you're using instance methods instead of static ones.
If you don't want to create an object, you should declare all your methods static, so something like
private static void methodName(Argument args...)
If you want a variable to be accessible by all these methods, you should initialise it outside the methods and to limit its scope, declare it private.
private static int[][] array = new int[3][5];
Global variables are usually looked down upon (especially for situations like your one) because in a large-scale program they can wreak havoc, so making it private will prevent some problems at the least.
Also, I'll say the usual: You should try to keep your code a bit tidy. Use descriptive class, method and variable names and keep your code neat (with proper indentation, linebreaks etc.) and consistent.
Here's a final (shortened) example of what your code should be like:
public class Test3 {
//Use this array in your methods
private static int[][] scores = new int[3][5];
/* Rather than just "Scores" name it so people know what
* to expect
*/
private static void createScores() {
//Code...
}
//Other methods...
/* Since you're now using static methods, you don't
* have to initialise an object and call its methods.
*/
public static void main(String[] args){
createScores();
MD(); //Don't know what these do
sumD(); //so I'll leave them.
}
}
Ideally, since you're using an array, you would create the array in the main method and pass it as an argument across each method, but explaining how that works is probably a whole new question on its own so I'll leave it at that.
You cannot put spaces around the =
sign when you do:
export foo=bar
Remove the spaces you have and you should be good to go.
If you type:
export foo = bar
the shell will interpret that as a request to export three names: foo
, =
and bar
. =
isn't a valid variable name, so the command fails. The variable name, equals sign and it's value must not be separated by spaces for them to be processed as a simultaneous assignment and export.
I also came across this issue trying to push via https to a repo using a self-signed SSL certificate.
The solution for me was running (from the local repository root):
git config http.sslVerify false
I do not like referring to the number, the sybolic name is much more expressive and avoid having to add a comment that could become obsolete over time.
So I'd rather do:
#pylint: disable-msg=too-many-arguments
And I would also recommend to not leave it dangling there: it will stay active until the file ends or it is disabled, whichever comes first.
So better doing:
#pylint: disable-msg=too-many-arguments
code_which_would_trigger_the_msg
#pylint: enable-msg=too-many-arguments
I would also recommend enabling/disabling one single warning/error per line.
Use HashMap
most of the times but use TreeMap
when you need the key to be sorted (when you need to iterate the keys).
I created a bit of a hybrid approach between Paul & Adam's approach:
The link that opens the array of links is already in the html. The jquery just creates the array of links and opens each one when the "open-all" button is clicked:
HTML:
<ul class="links">
<li><a href="http://www.google.com/"></a></li>
<li><a href="http://www.yahoo.com/"></a></li>
</ul>
<a id="open-all" href="#">OPEN ALL</a>
JQUERY:
$(function() { // On DOM content ready...
var hrefs = [];
$('.links a').each(function() {
hrefs.push(this.href); // Store the URLs from the links...
});
$('#open-all').click(function() {
for (var i in hrefs) {
window.open(hrefs[i]); // ...that opens each stored link in its own window when clicked...
}
});
});
You can check it out here: https://jsfiddle.net/daveaseeman/vonob51n/1/
You use the available API of JTable
and do not try to mess with the colors.
Some selection methods are available directly on the JTable
(like the setRowSelectionInterval
). If you want to have access to all selection-related logic, the selection model is the place to start looking
I just modified your code. It works fine in my system. See if this helps
class round{
public static void main(String args[]){
double a = 123.13698;
double roundOff = Math.round(a*100)/100.00;
System.out.println(roundOff);
}
}
Louis' answer is great, but I thought I would try to sum it up succinctly:
The bang operator tells the compiler to temporarily relax the "not null" constraint that it might otherwise demand. It says to the compiler: "As the developer, I know better than you that this variable cannot be null right now".
Do this to use a profile with name 'dev':
session = boto3.session.Session(profile_name='dev')
s3 = session.resource('s3')
for bucket in s3.buckets.all():
print(bucket.name)
if you want the original style of your Ui to remain and the title bar to be removed with no effect on that, you have to remove the title bar in your activity rather than the manifest. leave the original theme style that you had in the manifest and in each activity that you want no title bar use this.requestWindowFeature(Window.FEATURE_NO_TITLE);
in the oncreate()
method before setcontentview()
like this:
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
this.requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.activity_signup);
...
}
Note that datetime.datetime.fromtimestamp(timestamp) and .utcfromtimestamp(timestamp) fail on windows for dates before Jan. 1, 1970 while negative unix timestamps seem to work on unix-based platforms. The docs say this:

There is a a new option as well: get it via pip! There is a package pypiwin32 with wheels available, so you can just install with: pip install pypiwin32
!
Edit: Per comment from @movermeyer, the main project now publishes wheels at pywin32, and so can be installed with pip install pywin32
result = []
# Make a set of your "types":
input_set = set([tpl[1] for tpl in input])
>>> set(['ETH', 'KAT', 'NOT'])
# Iterate over the input_set
for type_ in input_set:
# a dict to gather things:
D = {}
# filter all tuples from your input with the same type as type_
tuples = filter(lambda tpl: tpl[1] == type_, input)
# write them in the D:
D["type"] = type_
D["itmes"] = [tpl[0] for tpl in tuples]
# append D to results:
result.append(D)

For each form data key you can set Content-Type, there is a postman button on the right to add the Content-Type column, and you don't have to parse a json from a string inside your Controller.
If you are using ES6 with NPM, you can try node module "fetch-jsonp". Fetch API Provides support for making a JsonP call as a regular XHR call.
Prerequisite:
you should be using isomorphic-fetch
node module in your stack.
I had the same error because I was using proxy. As the answer is given but in case you are using proxy then please set your proxy first using these commands:
git config --global http.proxy http://proxy_username:proxy_password@proxy_ip:port
git config --global https.proxy https://proxy_username:proxy_password@proxy_ip:port
Another approach if you want to use a varying portion of the dataset instead of a single value is to use rollapply(data, width, FUN, ...)
. Using a vector of widths allows you to apply a function on a varying window of the dataset. I've used this to build an adaptive filtering routine, though it isn't very efficient.
Seems like your view is typed dynamic
. Set the right type on the view and you'll see the error go away.
You cannot use items
instead iteritems
in all places in Python. For example, the following code:
class C:
def __init__(self, a):
self.a = a
def __iter__(self):
return self.a.iteritems()
>>> c = C(dict(a=1, b=2, c=3))
>>> [v for v in c]
[('a', 1), ('c', 3), ('b', 2)]
will break if you use items
:
class D:
def __init__(self, a):
self.a = a
def __iter__(self):
return self.a.items()
>>> d = D(dict(a=1, b=2, c=3))
>>> [v for v in d]
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: __iter__ returned non-iterator of type 'list'
The same is true for viewitems, which is available in Python 3.
Also, since items returns a copy of the dictionary’s list of (key, value)
pairs, it is less efficient, unless you want to create a copy anyway.
In Python 2, it is best to use iteritems
for iteration. The 2to3
tool can replace it with items
if you ever decide to upgrade to Python 3.
$('form :input').change(function() {
// Something has changed
});
You just need to set selector
of button
in your layout file.
<Button
android:id="@+id/button1"
android:background="@drawable/selector_xml_name"
android:layout_width="200dp"
android:layout_height="126dp"
android:text="Hello" />
and done.
Edit
Following is button_effect.xml
file in drawable
directory
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="@drawable/numpad_button_bg_selected" android:state_selected="true"></item>
<item android:drawable="@drawable/numpad_button_bg_pressed" android:state_pressed="true"></item>
<item android:drawable="@drawable/numpad_button_bg_normal"></item>
</selector>
In this, you can see that there are 3 drawables, you just need to place this button_effect
style to your button
, as i wrote above. You just need to replace selector_xml_name
with button_effect
.
I had the same problem, when i loaded a text file via fs.readFile()
, I tried to set the encodeing to UTF8, it keeped the same. my solution now is this:
myString = JSON.parse( JSON.stringify( myString ) )
after this an Ö is realy interpreted as an Ö.
All older answers' methods are deprecated by Google (supposedly because of troubles like this), since API 21 you need to use the Camera 2 API:
This class was deprecated in API level 21. We recommend using the new android.hardware.camera2 API for new applications.
In the newer API you have almost complete power over the Android device camera and documentation explicitly advice to
String[] getCameraIdList()
and then use obtained CameraId to open the camera:
void openCamera(String cameraId, CameraDevice.StateCallback callback, Handler handler)
99% of the frontal cameras have id = "1", and the back camera id = "0" according to this:
Non-removable cameras use integers starting at 0 for their identifiers, while removable cameras have a unique identifier for each individual device, even if they are the same model.
However, this means if device situation is rare like just 1-frontal -camera tablet you need to count how many embedded cameras you have, and place the order of the camera by its importance ("0"). So CAMERA_FACING_FRONT == 1 CAMERA_FACING_BACK == 0, which implies that the back camera is more important than frontal.
I don't know about a uniform method to identify the frontal camera on all Android devices. Simply said, the Android OS inside the device can't really find out which camera is exactly where for some reasons: maybe the only camera hardcoded id is an integer representing its importance or maybe on some devices whichever side you turn will be .. "back".
Documentation: https://developer.android.com/reference/android/hardware/camera2/package-summary.html
Explicit Examples: https://github.com/googlesamples/android-Camera2Basic
For the older API (it is not recommended, because it will not work on modern phones newer Android version and transfer is a pain-in-the-arse). Just use the same Integer CameraID (1) to open frontal camera like in this answer:
cam = Camera.open(1);
If you trust OpenCV to do the camera part:
Inside
<org.opencv.android.JavaCameraView
../>
use the following for the frontal camera:
opencv:camera_id="1"

You could use your own subclass of ExecutorCompletionService to wrap taskExecutor
, and your own implementation of BlockingQueue to get informed when each task completes and perform whatever callback or other action you desire when the number of completed tasks reaches your desired goal.
I had a similar problem today. I had a list of items that needed checking; if the objects passed the check, they were added to a result list. If they didn't pass, I changed them a bit and if they might still work (size > 0 after the change), I'd add them on to the back of the list for rechecking.
I went for a solution like
items = [...what I want to check...]
result = []
while items:
recheck_items = []
for item in items:
if check(item):
result.append(item)
else:
item = change(item) # Note that this always lowers the integer size(),
# so no danger of an infinite loop
if item.size() > 0:
recheck_items.append(item)
items = recheck_items # Let the loop restart with these, if any
My list is effectively a queue, should probably have used some sort of queue. But my lists are small (like 10 items) and this works too.

I have been working with Titanium for over a week now and feel like I have a good feel about its weakness.
1) If you hoping you use the same code on multiple platforms good luck! You'll see something like backgroundGradient and be amazed until you find out android version doesn't support it. Then have to revert to using a gradient image, might as well use it for both versions to make the code easier right?
2) A lot of weird behaviors, on the Titanium android sdk you need to understand what a "heavy" window is just to get the back button to work, or even better orientation event tracking. This isn't how the android platform really is, its just how Titanium tries to make their API work.
3) Your thrown in the dark, Things will crash and you have to start to comment code and then when you find it, never use it. There are certain obvious bugs, like orientation and percents on android that have been a problem for over six months.
4) Bugs .... there are a lot of bugs and they will be reported, sit around for months, get fixed in a few days. I am surprised they even are planning to release a black berry mobile sdk when there are so many other problems with android.
5) Titanium Iphone versus Titanium Android javascript engines are completely different. On android version you can download remote javascript files, include and use libraries like mootools, jquery and so on. I was in heaven when I found this out because I didn't have to keep compiling my android app. The android apk installation process takes so long! Iphone none of that is possible, also the iphone version has a much faster javascript engine.
If you stay away from a lot of the native UI parts, i.e instead use setInterval to detect orientation changes, sticking with gradient images, forget about the back button, build your own animations, forget window header, toolbars, and dashboard. You really can make an api that works on both that doesn't require of lot of rewriting. But at that points its just as sluggish as a webapp.
So is it worth it? After all the pain, its worth every minute. You can abstract the logic and just build different UI for each rather then if elseing everywhere. Titanium lets you make fluid applications, that feel fast. You lose the powerful layout abilities of each platform but if you think simple, things can get done under a single language.
Why not a web app? On entry level market android phones its horribly slow to generate a webview and consumes a lot of memory you could be using to do more complex logic.
if you work with pandas
what solved the issue for me was that i was trying to do calculations when I had NA values, the solution was to run:
df = df.dropna()
And after that the calculation that failed.
That's a difficult problem to solve since visually similar PDFs may have a wildly differing structure depending on how they were produced. In the worst case the library would need to basically act like an OCR. On the other hand, the PDF may contain sufficient structure and metadata for easy removal of tables and figures, which the library can be tailored to take advantage of.
I'm pretty sure there are no open source tools which solve your problem for a wide variety of PDFs, but I remember having heard of commercial software claiming to do exactly what you ask for. I'm sure you'll run into them while googling.
You could use sp_executesql
instead of exec
. That allows you to specify an output parameter.
declare @out_var varchar(max);
execute sp_executesql
N'select @out_var = ''hello world''',
N'@out_var varchar(max) OUTPUT',
@out_var = @out_var output;
select @out_var;
This prints "hello world".
Microsoft Virtual WiFi Miniport
should start and bind automatically to the underlying function driver. Try disabling and reenabling the AR9285

Thanks to this answer for pointing it out!
You need to understand the different between pass-by-reference and pass-by-value.
Basically, C only support pass-by-value. So you can't reference a variable directly when pass it to a function. If you want to change the variable out a function, which the swap do, you need to use pass-by-reference. To implement pass-by-reference in C, need to use pointer, which can dereference to the value.
The function:
void intSwap(int* a, int* b)
It pass two pointers value to intSwap, and in the function, you swap the values which a/b pointed to, but not the pointer itself. That's why R. Martinho & Dan Fego said it swap two integers, not pointers.
For chars, I think you mean string, are more complicate. String in C is implement as a chars array, which referenced by a char*, a pointer, as the string value. And if you want to pass a char* by pass-by-reference, you need to use the ponter of char*, so you get char**.
Maybe the code below more clearly:
typedef char* str;
void strSwap(str* a, str* b);
The syntax swap(int& a, int& b) is C++, which mean pass-by-reference directly. Maybe some C compiler implement too.
Hope I make it more clearly, not comfuse.
Amazon EC2 cannot offer Mac OS X EC2 instances due to Apple's tight licensing to only allow it to legally run on Apple hardware and the current EC2 infrastructure relies upon virtualized hardware.
Apple Mac image on Amazon EC2?
Can you run OS X on an Amazon EC2 instance?
There are other companies that do provide Mac OS X hosting, presumably on Apple hardware. One example is Go Daddy:

To find more, search for "Mac OS X hosting" and you'll find more options.
The onclick
attribute of a button takes a string of JavaScript, not an href like you provided. Just remove the "javascript:" part.

Rails has an except/except! method that returns the hash with those keys removed. If you're already using Rails, there's no sense in creating your own version of this.
class Hash
# Returns a hash that includes everything but the given keys.
# hash = { a: true, b: false, c: nil}
# hash.except(:c) # => { a: true, b: false}
# hash # => { a: true, b: false, c: nil}
#
# This is useful for limiting a set of parameters to everything but a few known toggles:
# @person.update(params[:person].except(:admin))
def except(*keys)
dup.except!(*keys)
end
# Replaces the hash without the given keys.
# hash = { a: true, b: false, c: nil}
# hash.except!(:c) # => { a: true, b: false}
# hash # => { a: true, b: false }
def except!(*keys)
keys.each { |key| delete(key) }
self
end
end
