Generally speaking, I tend to use path parameters when there is an obvious 'hierarchy' in the resource, such as:

/region/state/42

If that single resource has a status, one could:

/region/state/42/status

However, if 'region' is not really part of the resource being exposed, it probably belongs as one of the query parameters - similar to pagination (as you mentioned).

Change key in Project > Build Setting "typecheck calls to printf/scanf : NO"

Explanation : [How it works]

Check calls to printf and scanf, etc., to make sure that the arguments supplied have types appropriate to the format string specified, and that the conversions specified in the format string make sense.

Hope it work

Given answers are enough to deal with the problem but I want to share another way which may be introduced the new version of Spark (I am not sure about it) so given answer didn't catch it.

We can reach the column in spark statement with col("colum_name") keyword:

from pyspark.sql.functions import col , column
changedTypedf = joindf.withColumn("show", col("show").cast("double"))

You cannot. A basic numeric constant is considered an integer (or long if followed by a "L"), so you must explicitly downcast it to a byte to pass it as a parameter. As far as I know there is no shortcut.

in older bash (or in sh) that does not support declare -A, following style can be used to emulate key/value

# key
env=staging


# values
image_dev=gcr.io/abc/dev
image_staging=gcr.io/abc/stage
image_production=gcr.io/abc/stable

img_var_name=image_$env

# active_image=${!var_name}
active_image=$(eval "echo \$$img_var_name")

echo $active_image

Oh, that's an interesting beast.

I've spent considerable time of getting that right, there are three main issues that differs from locale to locale: - currency symbol and direction - thousand separator - decimal point

I've written my own rather extensive implementation of this which is part of the kiwi python framework, check out the LGPL:ed source here:

http://svn.async.com.br/cgi-bin/viewvc.cgi/kiwi/trunk/kiwi/currency.py?view=markup

The code is slightly Linux/Glibc specific, but shouldn't be too difficult to adopt to windows or other unixes.

Once you have that installed you can do the following:

>>> from kiwi.datatypes import currency
>>> v = currency('10.5').format()

Which will then give you:

'$10.50'

or

'10,50 kr'

Depending on the currently selected locale.

The main point this post has over the other is that it will work with older versions of python. locale.currency was introduced in python 2.5.

Callback for whenever a TR element is created for the table's body.

$('#example').dataTable( {
      "createdRow": function( row, data, dataIndex ) {
        if ( data[4] == "A" ) {
          $(row).addClass( 'important' );
        }
      }
    } );

There are 3 scenarios, you describe:

1. with 2 .c files and with int i; in the header.
2. With 2 .c files and with int i=100; in the header (or any other value; that doesn't matter).
3. With 1 .c file and with int i=100; in the header.

In each scenario, imagine the contents of the header file inserted into the .c file and this .c file compiled into a .o file and then these linked together.

Then following happens:

1. works fine because of the already mentioned "tentative definitions": every .o file contains one of them, so the linker says "ok".

2. doesn't work, because both .o files contain a definition with a value, which collide (even if they have the same value) - there may be only one with any given name in all .o files which are linked together at a given time.

3. works of course, because you have only one .o file and so no possibility for collision.

IMHO a clean thing would be

• to put either extern int i; or just int i; into the header file,
• and then to put the "real" definition of i (namely int i = 100;) into file1.c. In this case, this initialization gets used at the start of the program and the corresponding line in main() can be omitted. (Besides, I hope the naming is only an example; please don't name any global variables as i in real programs.)

I recommend you start reading the documentation (4.6.18. Formatting cells). When applying a lot of formatting it's better to use applyFromArray() According to the documentation this method is also suppose to be faster when you're setting many style properties. There's an annex where you can find all the possible keys for this function.

This will work for you:

$phpExcel = new PHPExcel();

$styleArray = array(
    'font'  => array(
        'bold'  => true,
        'color' => array('rgb' => 'FF0000'),
        'size'  => 15,
        'name'  => 'Verdana'
    ));

$phpExcel->getActiveSheet()->getCell('A1')->setValue('Some text');
$phpExcel->getActiveSheet()->getStyle('A1')->applyFromArray($styleArray);

To apply font style to complete excel document:

 $styleArray = array(
   'font'  => array(
        'bold'  => true,
        'color' => array('rgb' => 'FF0000'),
        'size'  => 15,
        'name'  => 'Verdana'
    ));      
 $phpExcel->getDefaultStyle()
    ->applyFromArray($styleArray);

You are looking for 2 options to java:

• -Xmx maximum heap size
• -Xms starting heap size

Put them in your command line invocation of the java executable, like this:

java -Xms512M -Xmx1024M my.package.MainClass

Keep in mind that you may want the starting and max heap sizes to be the same, depending on the application, as it avoids resizing the heap during runtime (which can take up time in applications that need to be responsive). Resizing the heap can entail moving a lot of objects around and redoing bookkeeping.

For every-day projects, make them whatever you think is good enough. Profile for help.

Unlike another programming languages, any variable declared outside any function automatically becomes global,

<script>

//declare global variable
var __foo = '123';

function __test(){
 //__foo is global and visible here
 alert(__foo);
}

//so, it will alert '123'
__test();

</script>

You problem is that you declare variable inside ready() function, which means that it becomes visible (in scope) ONLY inside ready() function, but not outside,

Solution: So just make it global, i.e declare this one outside $(document).ready(function(){});

Apparently the thread you refer is about C++.

In C your snippet will always work. I like the simpler if (p) { /* ... */ }.

The problem is

listModel.addElement(listaRosa.getSelectedValue());
listModel.removeElement(listaRosa.getSelectedValue());

you may be adding an element and immediatly removing it since both add and remove operations are on the same listModel.

Try

private void aggiungiTitolareButtonActionPerformed(java.awt.event.ActionEvent evt) {                                                       

    DefaultListModel lm2 = (DefaultListModel) listaTitolari.getModel();
    DefaultListModel lm1  = (DefaultListModel) listaRosa.getModel();
    if(lm2 == null)
    {
        lm2 = new DefaultListModel();
        listaTitolari.setModel(lm2);
    }
    lm2.addElement(listaTitolari.getSelectedValue());
    lm1.removeElement(listaTitolari.getSelectedValue());        
} 

You can do it with decorators like in this example below for TypeScript:

class YourClass {

    @Singleton static singleton() {}

}

function Singleton(target, name, descriptor) {
    var instance;
    descriptor.value = () => {
        if(!instance) instance = new target;
        return instance;
    };
}

Then you use your singleton like this:

var myInstance = YourClass.singleton();

As of this writing, decorators are not readily available in JavaScript engines. You would need to make sure your JavaScript runtime has decorators actually enabled or use compilers like Babel and TypeScript.

Also note that the singleton instance is created "lazy", i.e., it is created only when you use it for the first time.

import time  
current = time.time()

...job...
end = time.time()
diff = end - current

would that work for you?

cliff.meyers's original answer that suggested using <env-entry> will not help when using only System.getProperty()

According to the Tomcat 6.0 docs <env-entry> is for JNDI. So that means it won't have any effect on System.getProperty().

With the <env-entry> from cliff.meyers's example, the following code

System.getProperty("SMTP_PASSWORD");

will return null, not the value "abc123ftw".

According to the Tomcat 6 docs, to use <env-entry> you'd have to write code like this to use <env-entry>:

// Obtain our environment naming context
Context initCtx = new InitialContext();
Context envCtx = (Context) initCtx.lookup("java:comp/env");

// Look up our data source
String s = (String)envCtx.lookup("SMTP_PASSWORD");

Caveat: I have not actually tried the example above. But I have tried <env-entry> with System.getProperty(), and that definitely does not work.

Try this:

if [ $STATUS -ne 200 -a "$STRING" != "$VALUE" ]; then

You could declare a variable as a temporary table like this:

declare @myList table (Id int)

Which means you can use the insert statement to populate it with values:

insert into @myList values (1), (2), (5), (7), (10)

Then your select statement can use either the in statement:

select * from DBTable
where id in (select Id from @myList)

Or you could join to the temporary table like this:

select *
from DBTable d
join @myList t on t.Id = d.Id

And if you do something like this a lot then you could consider defining a user-defined table type so you could then declare your variable like this:

declare @myList dbo.MyTableType

BalusC is right. Version 1.0.13 is current, but 1.0.9 appears to have the required bundles:

$ jar tf lib/jfreechart-1.0.9.jar | grep LocalizationBundle.properties 
org/jfree/chart/LocalizationBundle.properties
org/jfree/chart/editor/LocalizationBundle.properties
org/jfree/chart/plot/LocalizationBundle.properties

Since "zebra" is a remote branch, I was thinking I don't have its data locally.

You are correct that you don't have the right data, but tried to resolve it in the wrong way. To collect data locally from a remote source, you need to use git fetch. When you did git checkout zebra you switched to whatever the state of that branch was the last time you fetched. So fetch from the remote first:

# fetch just the one remote
git fetch <remote>
# or fetch from all remotes
git fetch --all
# make sure you're back on the branch you want to cherry-pick to
git cherry-pick xyz

It's hard to infer what you're looking for from the question, but my best guess is as follows.

If we assume you have a DataFrame where some column is 'Category' and contains integers (or otherwise unique identifiers) for categories, then we can do the following.

Call the DataFrame dfrm, and assume that for each row, dfrm['Category'] is some value in the set of integers from 1 to N. Then,

for elem in dfrm['Category'].unique():
    dfrm[str(elem)] = dfrm['Category'] == elem

Now there will be a new indicator column for each category that is True/False depending on whether the data in that row are in that category.

If you want to control the category names, you could make a dictionary, such as

cat_names = {1:'Some_Treatment', 2:'Full_Treatment', 3:'Control'}
for elem in dfrm['Category'].unique():
    dfrm[cat_names[elem]] = dfrm['Category'] == elem

to result in having columns with specified names, rather than just string conversion of the category values. In fact, for some types, str() may not produce anything useful for you.

You can find online tools that use a dictionary to retrieve the original message.

In some cases, the dictionary method might just be useless:

• if the message is hashed using a SALT message
  
• if the message is hash more than once
  

For example, here is one MD5 decrypter online tool.

Using Node.js

sync mode:

var fs = require("fs");
var text = fs.readFileSync("./mytext.txt");
var textByLine = text.split("\n")

async mode:

var fs = require("fs");
fs.readFile("./mytext.txt", function(text){
    var textByLine = text.split("\n")
});

UPDATE

As of at least Node 6, readFileSync returns a Buffer, so it must first be converted to a string in order for split to work:

var text = fs.readFileSync("./mytext.txt").toString('utf-8');

Or

var text = fs.readFileSync("./mytext.txt", "utf-8");

Simplifying a bit, you can imagine map() doing something like this:

def mymap(func, lst):
    result = []
    for e in lst:
        result.append(func(e))
    return result

As you can see, it takes a function and a list, and returns a new list with the result of applying the function to each of the elements in the input list. I said "simplifying a bit" because in reality map() can process more than one iterable:

If additional iterable arguments are passed, function must take that many arguments and is applied to the items from all iterables in parallel. If one iterable is shorter than another it is assumed to be extended with None items.

For the second part in the question: What role does this play in making a Cartesian product? well, map() could be used for generating the cartesian product of a list like this:

lst = [1, 2, 3, 4, 5]

from operator import add
reduce(add, map(lambda i: map(lambda j: (i, j), lst), lst))

... But to tell the truth, using product() is a much simpler and natural way to solve the problem:

from itertools import product
list(product(lst, lst))

Either way, the result is the cartesian product of lst as defined above:

[(1, 1), (1, 2), (1, 3), (1, 4), (1, 5),
 (2, 1), (2, 2), (2, 3), (2, 4), (2, 5),
 (3, 1), (3, 2), (3, 3), (3, 4), (3, 5),
 (4, 1), (4, 2), (4, 3), (4, 4), (4, 5),
 (5, 1), (5, 2), (5, 3), (5, 4), (5, 5)]

• Use a dictionary when you have a set of unique keys that map to values.

• Use a list if you have an ordered collection of items.

• Use a set to store an unordered set of items.

I agree that Google's Gson is clear and easy to use. But you should create a result class for getting an instance from JSON string. If you can't clarify the result class, use json-simple:

// import static org.hamcrest.CoreMatchers.is;
// import static org.junit.Assert.assertThat;
// import org.json.simple.JSONObject;
// import org.json.simple.JSONValue;
// import org.junit.Test;

@Test
public void json2Object() {
    // given
    String jsonString = "{\"name\" : \"John\",\"age\" : \"20\","
            + "\"address\" : \"some address\","
            + "\"someobject\" : {\"field\" : \"value\"}}";

    // when
    JSONObject object = (JSONObject) JSONValue.parse(jsonString);

    // then
    @SuppressWarnings("unchecked")
    Set<String> keySet = object.keySet();
    for (String key : keySet) {
        Object value = object.get(key);
        System.out.printf("%s=%s (%s)\n", key, value, value.getClass()
                .getSimpleName());
    }

    assertThat(object.get("age").toString(), is("20"));
}

Pros and cons of Gson and json-simple is pretty much like pros and cons of user-defined Java Object and Map. The object you define is clear for all fields (name and type), but less flexible than Map.

Convert.ToString(object) converts to string. If the object is null, Convert.ToString converts it to an empty string.

Calling .ToString() on an object with a null value throws a System.NullReferenceException.

EDIT:

Two exceptions to the rules:

1) ConvertToString(string) on a null string will always return null.

2) ToString(Nullable<T>) on a null value will return "" .

Code Sample:

// 1) Objects:

object obj = null;

//string valX1 = obj.ToString();           // throws System.NullReferenceException !!!
string val1 = Convert.ToString(obj);    

Console.WriteLine(val1 == ""); // True
Console.WriteLine(val1 == null); // False


// 2) Strings

String str = null;
//string valX2 = str.ToString();    // throws System.NullReferenceException !!!
string val2 = Convert.ToString(str); 

Console.WriteLine(val2 == ""); // False
Console.WriteLine(val2 == null); // True            


// 3) Nullable types:

long? num = null;
string val3 = num.ToString();  // ok, no error

Console.WriteLine(num == null); // True
Console.WriteLine(val3 == "");  // True
Console.WriteLine(val3 == null); // False 

val3 = Convert.ToString(num);  

Console.WriteLine(num == null);  // True
Console.WriteLine(val3 == "");  // True
Console.WriteLine(val3 == null); // False

v = alli.max()
index = alli.argmax()
x, y = index/8, index%8

You can use to way below. It's very simple, but similar to the good answer given by Charlie Haley.

df1 = df.pop('b') # remove column b and store it in df1
df2 = df.pop('x') # remove column x and store it in df2
df['b']=df1 # add b series as a 'new' column.
df['x']=df2 # add b series as a 'new' column.

Now you have your dataframe with the columns 'b' and 'x' in the end. You can see this video from OSPY : https://youtu.be/RlbO27N3Xg4

One issue I noticed that could cause errors is that in rrichter's answer, the code below:

<img src="b.jpg" style="position: absolute; top: 30; left: 70;"/>

should include the px units within the style eg.

<img src="b.jpg" style="position: absolute; top: 30px; left: 70px;"/>

Other than that, the answer worked fine. Thanks.

There is a way simpler way. You put the href in a paragraph just created for that href. For example:

HREF name

NSArray *array = mutableArray;

This [mutableArray copy] antipattern is all over sample code. Stop doing so for throwaway mutable arrays that are transient and get deallocated at the end of the current scope.

There is no way the runtime could optimize out the wasteful copying of a mutable array that is just about to go out of scope, decrefed to 0 and deallocated for good.

one way to do this would be to use indexing with .loc.

Example

In the absence of an example dataframe, I'll make one up here:

import numpy as np
import pandas as pd

df = pd.DataFrame({'c1': list('abcdefg')})
df.loc[5, 'c1'] = 'Value'

>>> df
      c1
0      a
1      b
2      c
3      d
4      e
5  Value
6      g

Assuming you wanted to create a new column c2, equivalent to c1 except where c1 is Value, in which case, you would like to assign it to 10:

First, you could create a new column c2, and set it to equivalent as c1, using one of the following two lines (they essentially do the same thing):

df = df.assign(c2 = df['c1'])
# OR:
df['c2'] = df['c1']

Then, find all the indices where c1 is equal to 'Value' using .loc, and assign your desired value in c2 at those indices:

df.loc[df['c1'] == 'Value', 'c2'] = 10

And you end up with this:

>>> df
      c1  c2
0      a   a
1      b   b
2      c   c
3      d   d
4      e   e
5  Value  10
6      g   g

If, as you suggested in your question, you would perhaps sometimes just want to replace the values in the column you already have, rather than create a new column, then just skip the column creation, and do the following:

df['c1'].loc[df['c1'] == 'Value'] = 10
# or:
df.loc[df['c1'] == 'Value', 'c1'] = 10

Giving you:

>>> df
      c1
0      a
1      b
2      c
3      d
4      e
5     10
6      g

2⁹ = 512 values, because that's how many combinations of zeroes and ones you can have.

What those values represent however will depend on the system you are using. If it's an unsigned integer, you will have:

000000000 = 0 (min)
000000001 = 1
...
111111110 = 510
111111111 = 511 (max)

In two's complement, which is commonly used to represent integers in binary, you'll have:

000000000 = 0
000000001 = 1
...
011111110 = 254
011111111 = 255 (max)
100000000 = -256 (min) <- yay integer overflow
100000001 = -255
...
111111110 = -2
111111111 = -1

In general, with k bits you can represent 2^k values. Their range will depend on the system you are using:

Unsigned: 0 to 2^k-1
Signed: -2^k-1 to 2^k-1-1

Another approach is to filter using LINQ before the loop executes:

foreach ( int number in numbers.Where(n => n >= 0) )
{
    // process number
}

Is there really a difference between:

class User implements IUser

and

class UserImpl implements User

if all we're talking about is naming conventions?

Personally I prefer NOT preceding the interface with I as I want to be coding to the interface and I consider that to be more important in terms of the naming convention. If you call the interface IUser then every consumer of that class needs to know its an IUser. If you call the class UserImpl then only the class and your DI container know about the Impl part and the consumers just know they're working with a User.

Then again, the times I've been forced to use Impl because a better name doesn't present itself have been few and far between because the implementation gets named according to the implementation because that's where it's important, e.g.

class DbBasedAccountDAO implements AccountDAO
class InMemoryAccountDAO implements AccountDAO

Here's an alternative

Typescript:

function objectDefined <T>(obj: T): T {
  const acc: Partial<T> = {};
  for (const key in obj) {
    if (obj[key] !== undefined) acc[key] = obj[key];
  }
  return acc as T;
}

Javascript:

function objectDefined(obj) {
  const acc = {};
  for (const key in obj) {
    if (obj[key] !== undefined) acc[key] = obj[key];
  }
  return acc;
}

I referred a blog by Kim for doing this and its working fine for me. See the blog

The automated execution of macro can be accomplished with the help of a VB Script file which is being invoked by Windows Task Scheduler at specified times.

Remember to replace 'YourWorkbook' with the name of the workbook you want to open and replace 'YourMacro' with the name of the macro you want to run.

See the VB Script File (just named it RunExcel.VBS):

    ' Create a WshShell to get the current directory
Dim WshShell
Set WshShell = CreateObject("WScript.Shell")

' Create an Excel instance
Dim myExcelWorker
Set myExcelWorker = CreateObject("Excel.Application") 

' Disable Excel UI elements
myExcelWorker.DisplayAlerts = False
myExcelWorker.AskToUpdateLinks = False
myExcelWorker.AlertBeforeOverwriting = False
myExcelWorker.FeatureInstall = msoFeatureInstallNone

' Tell Excel what the current working directory is 
' (otherwise it can't find the files)
Dim strSaveDefaultPath
Dim strPath
strSaveDefaultPath = myExcelWorker.DefaultFilePath
strPath = WshShell.CurrentDirectory
myExcelWorker.DefaultFilePath = strPath

' Open the Workbook specified on the command-line 
Dim oWorkBook
Dim strWorkerWB
strWorkerWB = strPath & "\YourWorkbook.xls"

Set oWorkBook = myExcelWorker.Workbooks.Open(strWorkerWB)

' Build the macro name with the full path to the workbook
Dim strMacroName
strMacroName = "'" & strPath & "\YourWorkbook" & "!Sheet1.YourMacro"
on error resume next 
   ' Run the calculation macro
   myExcelWorker.Run strMacroName
   if err.number <> 0 Then
      ' Error occurred - just close it down.
   End If
   err.clear
on error goto 0 

oWorkBook.Save 

myExcelWorker.DefaultFilePath = strSaveDefaultPath

' Clean up and shut down
Set oWorkBook = Nothing

' Don’t Quit() Excel if there are other Excel instances 
' running, Quit() will shut those down also
if myExcelWorker.Workbooks.Count = 0 Then
   myExcelWorker.Quit
End If

Set myExcelWorker = Nothing
Set WshShell = Nothing

You can test this VB Script from command prompt:

>> cscript.exe RunExcel.VBS

Once you have the VB Script file and workbook tested so that it does what you want, you can then use Microsoft Task Scheduler (Control Panel-> Administrative Tools--> Task Scheduler) to execute ‘cscript.exe RunExcel.vbs’ automatically for you.

Please note the path of the macro should be in correct format and inside single quotes like:

strMacroName = "'" & strPath & "\YourWorkBook.xlsm'" & 
"!ModuleName.MacroName"

It is simply possible with childElementCount in pure javascript

var countItems = document.getElementsByTagName("ul")[0].childElementCount;_x000D_
console.log(countItems);

<div id="selected">_x000D_
  <ul>_x000D_
    <li>29</li>_x000D_
    <li>16</li>_x000D_
    <li>5</li>_x000D_
    <li>8</li>_x000D_
    <li>10</li>_x000D_
    <li>7</li>_x000D_
  </ul>_x000D_
</div>

If you use MyISAM tables, then you can recover any data you deleted, just

open file: mysql/data/[your_db]/[your_table].MYD

with any text editor

Just to add to what Cade said, this is usually a front-end display thing and should therefore be handled there. I know that sometimes it's easier to write something 100% in SQL for things like file export or other "SQL only" solutions, but most of the times this concatenation should be handled in your display layer.

fwrite($handle, "<br>"."\r\n");

Add this under

$password = $_POST['password'].PHP_EOL;

this. .

I was having the same problem so I decided to download the source kit and install it according to how you posted above...

1. Downloaded Source Kit
2. Opened command prompt on that folder and typed python setup.py build
3. Then I typed python setup.py install

It worked perfectly!

Now, some notes: when I typed python setup.py build, I saw that Microsoft Visual Studio v9.0 C compiler was being used to build everything.

So probably it's something with your compiler not correctly configured or something...

Anyways, that worked with me so thank you!

You can access the MySQL command line with XAMPP for Windows

1. click XAMPP icon to launch its cPanel

2. click on Shell button

3. Type this mysql -h localhost -u root and click enter

You should see all the command lines and what they do

Setting environment for using XAMPP for Windows.
Your PC c:\xampp

# mysql -h localhost - root

mysql  Ver 15.1 Distrib 10.1.19-MariaDB, for Win32 (AMD64)
Copyright (c) 2000, 2016, Oracle, MariaDB Corporation Ab and others.

Usage: mysql [OPTIONS] [database]

Default options are read from the following files in the given order:
C:\WINDOWS\my.ini C:\WINDOWS\my.cnf C:\my.ini C:\my.cnf C:\xampp\mysql\my.ini C:\xampp\mysql\my.cnf C:\xampp\mysql\bin\my.ini C:\xampp\mysql\bin\my.cnf
The following groups are read: mysql client client-server client-mariadb
The following options may be given as the first argument:
--print-defaults        Print the program argument list and exit.
--no-defaults           Don't read default options from any option file.
--defaults-file=#       Only read default options from the given file #.
--defaults-extra-file=# Read this file after the global files are read.

  -?, --help          Display this help and exit.
  -I, --help          Synonym for -?
  --abort-source-on-error
Abort 'source filename' operations in case of errors
  --auto-rehash       Enable automatic rehashing. One doesn't need to use
                      'rehash' to get table and field completion, but startup
                      and reconnecting may take a longer time. Disable with
                      --disable-auto-rehash.
                      (Defaults to on; use --skip-auto-rehash to disable.)
  -A, --no-auto-rehash
                      No automatic rehashing. One has to use 'rehash' to get
                      table and field completion. This gives a quicker start of
                      mysql and disables rehashing on reconnect.
  --auto-vertical-output
                      Automatically switch to vertical output mode if the
                      result is wider than the terminal width.
  -B, --batch         Don't use history file. Disable interactive behavior.
                      (Enables --silent.)
  --character-sets-dir=name
                      Directory for character set files.
  --column-type-info  Display column type information.
  -c, --comments      Preserve comments. Send comments to the server. The
                      default is --skip-comments (discard comments), enable
                      with --comments.
  -C, --compress      Use compression in server/client protocol.
  -#, --debug[=#]     This is a non-debug version. Catch this and exit.
  --debug-check       Check memory and open file usage at exit.
  -T, --debug-info    Print some debug info at exit.
  -D, --database=name Database to use.
  --default-character-set=name
                      Set the default character set.
  --delimiter=name    Delimiter to be used.
  -e, --execute=name  Execute command and quit. (Disables --force and history
                      file.)
  -E, --vertical      Print the output of a query (rows) vertically.
  -f, --force         Continue even if we get an SQL error. Sets
                      abort-source-on-error to 0
  -G, --named-commands
                      Enable named commands. Named commands mean this program's
                      internal commands; see mysql> help . When enabled, the
                      named commands can be used from any line of the query,
                      otherwise only from the first line, before an enter.
                      Disable with --disable-named-commands. This option is
                      disabled by default.
  -i, --ignore-spaces Ignore space after function names.
  --init-command=name SQL Command to execute when connecting to MySQL server.
                      Will automatically be re-executed when reconnecting.
  --local-infile      Enable/disable LOAD DATA LOCAL INFILE.
  -b, --no-beep       Turn off beep on error.
  -h, --host=name     Connect to host.
  -H, --html          Produce HTML output.
  -X, --xml           Produce XML output.
  --line-numbers      Write line numbers for errors.
                      (Defaults to on; use --skip-line-numbers to disable.)
  -L, --skip-line-numbers
                      Don't write line number for errors.
  -n, --unbuffered    Flush buffer after each query.
  --column-names      Write column names in results.
                      (Defaults to on; use --skip-column-names to disable.)
  -N, --skip-column-names
                      Don't write column names in results.
  --sigint-ignore     Ignore SIGINT (CTRL-C).
  -o, --one-database  Ignore statements except those that occur while the
                      default database is the one named at the command line.
  -p, --password[=name]
                      Password to use when connecting to server. If password is
                      not given it's asked from the tty.
  -W, --pipe          Use named pipes to connect to server.
  -P, --port=#        Port number to use for connection or 0 for default to, in
                      order of preference, my.cnf, $MYSQL_TCP_PORT,
                      /etc/services, built-in default (3306).
  --progress-reports  Get progress reports for long running commands (like
                      ALTER TABLE)
                      (Defaults to on; use --skip-progress-reports to disable.)
  --prompt=name       Set the mysql prompt to this value.
  --protocol=name     The protocol to use for connection (tcp, socket, pipe,
                      memory).
  -q, --quick         Don't cache result, print it row by row. This may slow
                      down the server if the output is suspended. Doesn't use
                      history file.
  -r, --raw           Write fields without conversion. Used with --batch.
  --reconnect         Reconnect if the connection is lost. Disable with
                      --disable-reconnect. This option is enabled by default.
                      (Defaults to on; use --skip-reconnect to disable.)
  -s, --silent        Be more silent. Print results with a tab as separator,
                      each row on new line.
  --shared-memory-base-name=name
                      Base name of shared memory.
  -S, --socket=name   The socket file to use for connection.
  --ssl               Enable SSL for connection (automatically enabled with
                      other flags).
  --ssl-ca=name       CA file in PEM format (check OpenSSL docs, implies
                      --ssl).
  --ssl-capath=name   CA directory (check OpenSSL docs, implies --ssl).
  --ssl-cert=name     X509 cert in PEM format (implies --ssl).
  --ssl-cipher=name   SSL cipher to use (implies --ssl).
  --ssl-key=name      X509 key in PEM format (implies --ssl).
  --ssl-crl=name      Certificate revocation list (implies --ssl).
  --ssl-crlpath=name  Certificate revocation list path (implies --ssl).
  --ssl-verify-server-cert
                      Verify server's "Common Name" in its cert against
                      hostname used when connecting. This option is disabled by

                      also. Does not work in batch mode. Disable with
                      --disable-tee. This option is disabled by default.
  -u, --user=name     User for login if not current user.
  -U, --safe-updates  Only allow UPDATE and DELETE that uses keys.
  -U, --i-am-a-dummy  Synonym for option --safe-updates, -U.

  -V, --version       Output version information and exit.
  -w, --wait          Wait and retry if connection is down.
  --connect-timeout=# Number of seconds before connection timeout.
  --max-allowed-packet=#
                      The maximum packet length to send to or receive from
                      server.
  --net-buffer-length=#
                      The buffer size for TCP/IP and socket communication.

  --binary-mode       By default, ASCII '\0' is disallowed and '\r\n' is
                      translated to '\n'. This switch turns off both features,
                      and also turns off parsing of all clientcommands except
                      \C and DELIMITER, in non-interactive mode (for input
                      piped to mysql or loaded using the 'source' command).
                      This is necessary when processing output from mysqlbinlog
                      that may contain blobs.

template <typename T>
std::vector<T> initVector (int len, ...)
{

  va_list vl;
  va_start(vl, len);
  for (int i = 0; i < len; ++i)
    v.push_back(va_arg(vl, T));
  va_end(vl);
  return v;

int main ()

I have just uploaded this Vim plugin for the development of Java Maven projects.

And don't forget to set the highlighting if you haven't already:

https://github.com/sentientmachine/erics_vim_syntax_and_color_highlighting

You can fix your example with the iterator pattern by changing the parametrization of the class:

List<Room> rooms = new ArrayList<Room>();
rooms.add(room1);
rooms.add(room2);
for(Iterator<Room> i = rooms.iterator(); i.hasNext(); ) {
  String item = i.next();
  System.out.println(item);
}

or much simpler way:

List<Room> rooms = new ArrayList<Room>();
rooms.add(room1);
rooms.add(room2);
for(Room room : rooms) {
  System.out.println(room);
}

If you want to change ng-view you'll have to use the '#'

$window.location.href= "#operation";

ArrayList implements the List Interface.

If you look at the Javadoc for List at the contains method you will see that it uses the equals() method to evaluate if two objects are the same.

You don't have that kind of control with a bare a tag. But you can hook up the tag's onclick handler to call window.open(...) with the right parameters. See here for examples: https://developer.mozilla.org/En/DOM/Window.open

I still don't think you can force window over tab directly though-- that depends on the browser and the user's settings.

Using a CLI, the easiest way (cross-platform) I've found is to use the NPM package https://github.com/sindresorhus/open-cli

npm install --global open-cli

Installing it globally allows running something like open-cli https://unlyed.github.io/next-right-now/.

You can also install it locally (e.g: in a project) and run npx open-cli https://unlyed.github.io/next-right-now/

Or, using a NPM script (which is how I actually use it): "doc:online": "open-cli https://unlyed.github.io/next-right-now/",

Running yarn doc:online will open the webpage, and this works on any platform (windows, mac, linux).

add in manifiest file ,

  android:theme="@android:style/Theme.Translucent.NoTitleBar"

add following line into ur java file,

  this.requestWindowFeature(Window.FEATURE_NO_TITLE);

I had this path in my machine:

C:/xampp5.0/htdocs/project-recordando-symfony/project-recordando-symfony

Then I ran composer install or/and composer update and it returned this error:

ErrorException ZipArchive::extractTo...

That error is because your path is too much long, I changed to:

C:/xampp5.0/htdocs/p-symfony/*

and worked!

Git doesn't think in terms of file versions. A version in git is a snapshot of the entire tree.

Given this, what you really want is a tree that has the latest content of most files, but with the contents of one file the same as it was 5 commits ago. This will take the form of a new commit on top of the old ones, and the latest version of the tree will have what you want.

I don't know if there's a one-liner that will revert a single file to the contents of 5 commits ago, but the lo-fi solution should work: checkout master~5, copy the file somewhere else, checkout master, copy the file back, then commit.

Maybe it is time to start revising this answer? Personally I would vote for setActive() and unsetActive() (alternatives can be setUnActive(), notActive(), disable(), etc. depending on context) since "setActive" implies you activate it at all times, which you don't. It's kind of counter intuitive to say "setActive" but actually remove the active state.

Another problem is, you can can not listen to specifically a SetActive event in a CQRS way, you would need to listen to a 'setActiveEvent' and determine inside that listener wether is was actually set active or not. Or of course determine which event to call when calling setActive() but that then goes against the Separation of Concerns principle.

A good read on this is the FlagArgument article by Martin Fowler: http://martinfowler.com/bliki/FlagArgument.html

However, I come from a PHP background and see this trend being adopted more and more. Not sure how much this lives with Java development.

Above suggestions didn't worked for me. I got it running on my windows, using inspiration from http://butlerccwebdev.net/support/testingserver/vhosts-setup-win.html

For Http inside httpd-vhosts.conf

AllowOverride All
Require all granted
</Directory>

##Letzgrow
<VirtualHost *:80>
DocumentRoot "D:/Projects/letzgrow"
ServerName letz.dev
ServerAlias letz.dev

For using Https (Open SSL) inside httpd-ssl.conf

##Letzgrow

Hope it helps someone !!

If you still need to server static locally (e.g. for testing without debug) you can run devserver in insecure mode:

manage.py runserver --insecure

"ModelState.IsValid" tells you that the model is consumed by the view (i.e. PaymentAdviceEntity) is satisfy all types of validation or not specified in the model properties by DataAnotation.

In this code the view does not bind any model properties. So if you put any DataAnotations or validation in model (i.e. PaymentAdviceEntity). then the validations are not satisfy. say if any properties in model is Name which makes required in model.Then the value of the property remains blank after post.So the model is not valid (i.e. ModelState.IsValid returns false). You need to remove the model level validations.

If you are trying to debug your virtual host configuration, you may find the Apache -S command line switch useful. That is, type the following command:

httpd -S

This command will dump out a description of how Apache parsed the configuration file. Careful examination of the IP addresses and server names may help uncover configuration mistakes. (See the docs for the httpd program for other command line options).

"\t" not '\t', php doesnt escape in single quotes

Without over-complicating the problem, to grant the EXECUTE on chosen database:

USE [DB]
GRANT EXEC TO [User_Name];

Java ArrayList has an indexOf method. Java arrays have no such method.

I'm guessing from your last question, asked 20 minutes before this one, that you are trying to parse (read and convert) the XML found through using GeoNames' FindNearestAddress.

If your XML is in a string variable called txt and looks like this:

<address>
  <street>Roble Ave</street>
  <mtfcc>S1400</mtfcc>
  <streetNumber>649</streetNumber>
  <lat>37.45127</lat>
  <lng>-122.18032</lng>
  <distance>0.04</distance>
  <postalcode>94025</postalcode>
  <placename>Menlo Park</placename>
  <adminCode2>081</adminCode2>
  <adminName2>San Mateo</adminName2>
  <adminCode1>CA</adminCode1>
  <adminName1>California</adminName1>
  <countryCode>US</countryCode>
</address>

Then you can parse the XML with Javascript DOM like this:

if (window.DOMParser)
{
    parser = new DOMParser();
    xmlDoc = parser.parseFromString(txt, "text/xml");
}
else // Internet Explorer
{
    xmlDoc = new ActiveXObject("Microsoft.XMLDOM");
    xmlDoc.async = false;
    xmlDoc.loadXML(txt);
}

And get specific values from the nodes like this:

//Gets house address number
xmlDoc.getElementsByTagName("streetNumber")[0].childNodes[0].nodeValue;

//Gets Street name
xmlDoc.getElementsByTagName("street")[0].childNodes[0].nodeValue;

//Gets Postal Code
xmlDoc.getElementsByTagName("postalcode")[0].childNodes[0].nodeValue;

JSFiddle

Feb. 2019 edit:

In response to @gaugeinvariante's concerns about xml with Namespace prefixes. Should you have a need to parse xml with Namespace prefixes, everything should work almost identically:

NOTE: this will only work in browsers that support xml namespace prefixes such as Microsoft Edge

// XML with namespace prefixes 's', 'sn', and 'p' in a variable called txt_x000D_
txt = `_x000D_
<address xmlns:p='example.com/postal' xmlns:s='example.com/street' xmlns:sn='example.com/streetNum'>_x000D_
  <s:street>Roble Ave</s:street>_x000D_
  <sn:streetNumber>649</sn:streetNumber>_x000D_
  <p:postalcode>94025</p:postalcode>_x000D_
</address>`;_x000D_
_x000D_
//Everything else the same_x000D_
if (window.DOMParser)_x000D_
{_x000D_
    parser = new DOMParser();_x000D_
    xmlDoc = parser.parseFromString(txt, "text/xml");_x000D_
}_x000D_
else // Internet Explorer_x000D_
{_x000D_
    xmlDoc = new ActiveXObject("Microsoft.XMLDOM");_x000D_
    xmlDoc.async = false;_x000D_
    xmlDoc.loadXML(txt);_x000D_
}_x000D_
_x000D_
//The prefix should not be included when you request the xml namespace_x000D_
//Gets "streetNumber" (note there is no prefix of "sn"_x000D_
console.log(xmlDoc.getElementsByTagName("streetNumber")[0].childNodes[0].nodeValue);_x000D_
_x000D_
//Gets Street name_x000D_
console.log(xmlDoc.getElementsByTagName("street")[0].childNodes[0].nodeValue);_x000D_

Try via context.getResources().getDisplayMetrics() if you have a context available.

This will do it for you:

var yourSelect = document.getElementById( "your-select-id" );
alert( yourSelect.options[ yourSelect.selectedIndex ].value )

3 - It doesn't matter.

BUT, I tend to only use a <span> inside an <a> if it's only for a part of the contents of the tag i.e.

<a href="#">some <span class="red">text</span></a>

Rather than:

<a href="#"><span class="red">some text</span></a>

Which should obviously just be:

<a href="#" class="red">some text</a>

Note the guidelines for performing work on a UI thread, collected on my blog:

• Don't block the UI thread for more than 50ms at a time.
• You can schedule ~100 continuations on the UI thread per second; 1000 is too much.

There are two techniques you should use:

1) Use ConfigureAwait(false) when you can.

E.g., await MyAsync().ConfigureAwait(false); instead of await MyAsync();.

ConfigureAwait(false) tells the await that you do not need to resume on the current context (in this case, "on the current context" means "on the UI thread"). However, for the rest of that async method (after the ConfigureAwait), you cannot do anything that assumes you're in the current context (e.g., update UI elements).

For more information, see my MSDN article Best Practices in Asynchronous Programming.

2) Use Task.Run to call CPU-bound methods.

You should use Task.Run, but not within any code you want to be reusable (i.e., library code). So you use Task.Run to call the method, not as part of the implementation of the method.

So purely CPU-bound work would look like this:

// Documentation: This method is CPU-bound.
void DoWork();

Which you would call using Task.Run:

await Task.Run(() => DoWork());

Methods that are a mixture of CPU-bound and I/O-bound should have an Async signature with documentation pointing out their CPU-bound nature:

// Documentation: This method is CPU-bound.
Task DoWorkAsync();

Which you would also call using Task.Run (since it is partially CPU-bound):

await Task.Run(() => DoWorkAsync());

You can use Google Page Speed API to achieve your task easily. In my current project, I have used Google Page Speed API`s query written in Python to capture screenshots of any Web URL provided and save it to a location. Have a look.

import urllib2
import json
import base64
import sys
import requests
import os
import errno

#   The website's URL as an Input
site = sys.argv[1]
imagePath = sys.argv[2]

#   The Google API.  Remove "&strategy=mobile" for a desktop screenshot
api = "https://www.googleapis.com/pagespeedonline/v1/runPagespeed?screenshot=true&strategy=mobile&url=" + urllib2.quote(site)

#   Get the results from Google
try:
    site_data = json.load(urllib2.urlopen(api))
except urllib2.URLError:
    print "Unable to retreive data"
    sys.exit()

try:
    screenshot_encoded =  site_data['screenshot']['data']
except ValueError:
    print "Invalid JSON encountered."
    sys.exit()

#   Google has a weird way of encoding the Base64 data
screenshot_encoded = screenshot_encoded.replace("_", "/")
screenshot_encoded = screenshot_encoded.replace("-", "+")

#   Decode the Base64 data
screenshot_decoded = base64.b64decode(screenshot_encoded)

if not os.path.exists(os.path.dirname(impagepath)):
    try:
        os.makedirs(os.path.dirname(impagepath))
        except  OSError as exc:
            if exc.errno  != errno.EEXIST:
                raise

#   Save the file
with open(imagePath, 'w') as file_:
    file_.write(screenshot_decoded)

Unfortunately, following are the drawbacks. If these do not matter, you can proceed with Google Page Speed API. It works well.

• The maximum width is 320px
• According to Google API Quota, there is a limit of 25,000 requests per day

Try this:

    ServersTable.Columns.Clear();
    ServersTable.DataSource = SBind;

If you don't want to clear all the existing columns, you have to set DataPropertyName for each existing column like this:

for (int i = 0; i < ServersTable.ColumnCount; ++i) {
  DTable.Columns.Add(new DataColumn(ServersTable.Columns[i].Name));
  ServersTable.Columns[i].DataPropertyName = ServersTable.Columns[i].Name;
}

Or simply:

PRINT SUBSTRING(@SQL_InsertQuery, 1, 8000)
PRINT SUBSTRING(@SQL_InsertQuery, 8001, 16000)

import android.graphics.Matrix
public Bitmap getResizedBitmap(Bitmap bm, int newWidth, int newHeight) {
    int width = bm.getWidth();
    int height = bm.getHeight();
    float scaleWidth = ((float) newWidth) / width;
    float scaleHeight = ((float) newHeight) / height;
    // CREATE A MATRIX FOR THE MANIPULATION
    Matrix matrix = new Matrix();
    // RESIZE THE BIT MAP
    matrix.postScale(scaleWidth, scaleHeight);

    // "RECREATE" THE NEW BITMAP
    Bitmap resizedBitmap = Bitmap.createBitmap(
        bm, 0, 0, width, height, matrix, false);
    bm.recycle();
    return resizedBitmap;
}

EDIT: as suggested by by @aveschini, I have added bm.recycle(); for memory leaks. Please note that in case if you are using the previous object for some other purposes, then handle accordingly.

TLDR; The formula is n(n-1)/2 where n is the number of items in the set.

Explanation:

To find the number of unique pairs in a set, where the pairs are subject to the commutative property (AB = BA), you can calculate the summation of 1 + 2 + ... + (n-1) where n is the number of items in the set.

The reasoning is as follows, say you have 4 items:

A
B
C
D

The number of items that can be paired with A is 3, or n-1:

AB
AC
AD

It follows that the number of items that can be paired with B is n-2 (because B has already been paired with A):

BC
BD

and so on...

(n-1) + (n-2) + ... + (n-(n-1))

which is the same as

1 + 2 + ... + (n-1)

or

n(n-1)/2

Use the pandas.DataFrame.rename funtion. Check this link for description.

data.rename(columns = {'gdp': 'log(gdp)'}, inplace = True)

If you intend to rename multiple columns then

data.rename(columns = {'gdp': 'log(gdp)', 'cap': 'log(cap)', ..}, inplace = True)

import java.util.ArrayList;
import java.util.List;

public class Test {
    public static void main(String[] args) {
        for (String part : getParts("foobarspam", 3)) {
            System.out.println(part);
        }
    }
    private static List<String> getParts(String string, int partitionSize) {
        List<String> parts = new ArrayList<String>();
        int len = string.length();
        for (int i=0; i<len; i+=partitionSize)
        {
            parts.add(string.substring(i, Math.min(len, i + partitionSize)));
        }
        return parts;
    }
}

This is the most simple method to generate unique random values in a range or from an array.

In this example, I will be using a predefined array but you can adapt this method to generate random numbers as well. First, we will create a sample array to retrieve our data from.

1. Generate a random number and add it to the new array.
2. Generate another random number and check if it is already stored in the new array.
3. If not then add it and continue
4. else reiterate the step.

ArrayList<Integer> sampleList = new ArrayList<>();
sampleList.add(1);
sampleList.add(2);
sampleList.add(3);
sampleList.add(4);
sampleList.add(5);
sampleList.add(6);
sampleList.add(7);
sampleList.add(8);

Now from the sampleList we will produce five random numbers that are unique.

int n;
randomList = new ArrayList<>();
for(int  i=0;i<5;i++){
    Random random = new Random();
    n=random.nextInt(8);     //Generate a random index between 0-7

    if(!randomList.contains(sampleList.get(n)))
    randomList.add(sampleList.get(n));
    else
        i--;    //reiterating the step
}
        

This is conceptually very simple. If the random value generated already exists then we will reiterate the step. This will continue until all the values generated are unique.

If you found this answer useful then you can vote it up as it is much simple in concept as compared to the other answers.

When formatting number to 2 decimal places you have two options TRUNCATE and ROUND. You are looking for TRUNCATE function.

Examples:

Without rounding:

TRUNCATE(0.166, 2)
-- will be evaluated to 0.16

TRUNCATE(0.164, 2)
-- will be evaluated to 0.16

docs: http://www.w3resource.com/mysql/mathematical-functions/mysql-truncate-function.php

With rounding:

ROUND(0.166, 2)
-- will be evaluated to 0.17

ROUND(0.164, 2)
-- will be evaluated to 0.16

docs: http://www.w3resource.com/mysql/mathematical-functions/mysql-round-function.php

You can repaint and / or requery:

On the close event of form B:

Forms!FormA.Requery

Is this what you mean?

Other answers are over complicating things. This question is simply logic question. Just get your statement right.

$boolString = 'false';
$result = 'true' === $boolString;

Now your answer will be either

• false, if the string was 'false',
• or true, if your string was 'true'.

I have to note that filter_var( $boolString, FILTER_VALIDATE_BOOLEAN ); still will be a better option if you need to have strings like on/yes/1 as alias for true.

You may need to set up a billing account when you try to enable the Google Cloud Translation API in your account.

Below is a quick start example which translates two English strings to Spanish:

import com.google.api.client.json.gson.GsonFactory;
import com.google.api.services.translate.Translate;
import com.google.api.services.translate.model.TranslationsListResponse;
import com.google.api.services.translate.model.TranslationsResource;

public class QuickstartSample
{
    public static void main(String[] arguments) throws IOException, GeneralSecurityException
    {
        Translate t = new Translate.Builder(
                GoogleNetHttpTransport.newTrustedTransport()
                , GsonFactory.getDefaultInstance(), null)
                // Set your application name
                .setApplicationName("Stackoverflow-Example")
                .build();
        Translate.Translations.List list = t.new Translations().list(
                Arrays.asList(
                        // Pass in list of strings to be translated
                        "Hello World",
                        "How to use Google Translate from Java"),
                // Target language
                "ES");

        // TODO: Set your API-Key from https://console.developers.google.com/
        list.setKey("your-api-key");
        TranslationsListResponse response = list.execute();
        for (TranslationsResource translationsResource : response.getTranslations())
        {
            System.out.println(translationsResource.getTranslatedText());
        }
    }

For those who came here looking for a command-line solution, like me, cURL's --data-urlencode works fine:

curl -G -v -s --data-urlencode 'query={"type" : "/music/artist"}' 'https://www.googleapis.com/freebase/v1/mqlread'

sends

GET /freebase/v1/mqlread?query=%7B%22type%22%20%3A%20%22%2Fmusic%2Fartist%22%7D HTTP/1.1

, for example. Larger JSON data can be put in a file and you'd use the @ syntax to specify a file to slurp in the to-be-escaped data from. For example, if

$ cat 1.json 
{
  "type": "/music/artist",
  "name": "The Police",
  "album": []
}

you'd use

curl -G -v -s --data-urlencode [email protected] 'https://www.googleapis.com/freebase/v1/mqlread'

And now, this is also a tutorial on how to query Freebase from the command line :-)

@Presto Thanks! Yours worked perfectly for me, but I came up with a simpler version to save changing everything around.

Add a <span> tag around the desired link text, specifying class within. (e.g. home tag)

<nav id="top-menu">
    <ul>
        <li> <a href="home.html"><span class="currentLink">Home</span></a> </li>
        <li> <a href="about.html">About</a> </li>
        <li> <a href="cv.html">CV</a> </li>
        <li> <a href="photos.html">Photos</a> </li>
        <li> <a href="archive.html">Archive</a> </li>
        <li> <a href="contact.html">Contact</a></li>
    </ul>
</nav>

Then edit your CSS accordingly:

.currentLink {
    color:#baada7;
}

If you need to work a lot with database in your code and you know the structure of your table, I suggest you do it as follow:

First of all you can define a class which will help you to make objects capable of keeping your table rows data. For example in my project I created a class named Document.java to keep data of a single document from my database and I made an array list of these objects to keep data of my table which is gain by a query.

package financialdocuments;

import java.lang.*;
import java.util.HashMap;

/**
 *
 * @author Administrator
 */
public class Document {

 private int document_number; 
 private boolean document_type;
 private boolean document_status; 
 private StringBuilder document_date;
 private StringBuilder document_statement;
 private int document_code_number;
 private int document_employee_number;
 private int document_client_number;
 private String document_employee_name;
 private String document_client_name;
 private long document_amount;
 private long document_payment_amount;

 HashMap<Integer,Activity> document_activity_hashmap;


public Document(int dn,boolean dt,boolean ds,String dd,String dst,int dcon,int den,int dcln,long da,String dena,String dcna){

    document_date = new StringBuilder(dd);
    document_date.setLength(10);
    document_date.setCharAt(4, '.');
    document_date.setCharAt(7, '.');
    document_statement = new StringBuilder(dst);
    document_statement.setLength(50);
    document_number = dn; 
    document_type = dt;
    document_status = ds;
    document_code_number = dcon;
    document_employee_number = den;
    document_client_number = dcln;
    document_amount = da;
    document_employee_name = dena;
    document_client_name = dcna;

    document_payment_amount = 0;

    document_activity_hashmap = new HashMap<>();

}

public Document(int dn,boolean dt,boolean ds, long dpa){

    document_number = dn; 
    document_type = dt;
    document_status = ds;

    document_payment_amount = dpa;

    document_activity_hashmap = new HashMap<>();

}

// Print document information 
public void printDocumentInformation (){
    System.out.println("Document Number:" + document_number); 
    System.out.println("Document Date:" + document_date); 
    System.out.println("Document Type:" + document_type); 
    System.out.println("Document Status:" + document_status); 
    System.out.println("Document Statement:" + document_statement); 
    System.out.println("Document Code Number:" + document_code_number); 
    System.out.println("Document Client Number:" + document_client_number); 
    System.out.println("Document Employee Number:" + document_employee_number); 
    System.out.println("Document Amount:" + document_amount); 
    System.out.println("Document Payment Amount:" + document_payment_amount); 
    System.out.println("Document Employee Name:" + document_employee_name); 
    System.out.println("Document Client Name:" + document_client_name); 

} 
} 

Second of all, you can define a class to handle your database needs. For example I defined a class named DataBase.java which handles my connections to the database and my needed queries. And I instantiated an objected of it in my main class.

package financialdocuments;

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;
import java.util.ArrayList;
import java.util.HashMap;
import java.util.logging.Level;
import java.util.logging.Logger;

private ResultSet result;

// Strings needed to set connection

I hope this could be a little help.

On my system: CentOS 5

I can use \s outside of collections but have to use [:space:] inside of collections. In fact I can use [:space:] only inside collections. So to match a single space using this I have to use [[:space:]] Which is really strange.

echo a b cX | sed -r "s/(a\sb[[:space:]]c[^[:space:]])/Result: \1/"

Result: a b cX

• first space I match with \s
• second space I match alternatively with [[:space:]]
• the X I match with "all but no space" [^[:space:]]

These two will not work:

a[:space:]b  instead use a\sb or a[[:space:]]b

a[^\s]b      instead use a[^[:space:]]b

First, create an angular filter using LoDash:

angular.module('myApp').filter('times', function(){
   return function(value){
      return _.times(value || 0);
   }
});

The LoDash times function is capable of handling null, undefined, 0, numbers, and string representation of numbers.

Then, use it in your HTML as this:

<span ng-repeat="i in 5 | times">
 <!--DO STUFF-->
</span>

or

<span ng-repeat="i in myVar | times">
 <!--DO STUFF-->
</span>

memory mapping is not only used to map files into memory but is also a tool to request RAM from kernel. These are those inode 0 entries - your stack, heap, bss segments and more

I ended up using ideas from this post to come up with a solution that is pretty similar to AtZako's version.

 jQuery.fn.preventDoubleSubmission = function() {

    var last_clicked, time_since_clicked;

    $(this).bind('submit', function(event){

    if(last_clicked) 
      time_since_clicked = event.timeStamp - last_clicked;

    last_clicked = event.timeStamp;

    if(time_since_clicked < 2000)
      return false;

    return true;
  });   
};

Using like this:

$('#my-form').preventDoubleSubmission();

I found that the solutions that didn't include some kind of timeout but just disabled submission or disabled form elements caused problems because once the lock-out is triggered you can't submit again until you refresh the page. That causes some problems for me when doing ajax stuff.

This can probably be prettied up a bit as its not that fancy.

• laravel site load with domain/public/index.php
• laravel project does not redirect correctly

If the column is not in the WHERE/JOIN/GROUP BY/ORDER BY, but only in the column list in the SELECT clause is where you use INCLUDE.

The INCLUDE clause adds the data at the lowest/leaf level, rather than in the index tree. This makes the index smaller because it's not part of the tree

INCLUDE columns are not key columns in the index, so they are not ordered. This means it isn't really useful for predicates, sorting etc as I mentioned above. However, it may be useful if you have a residual lookup in a few rows from the key column(s)

Another MSDN article with a worked example

why not

def pairwise(iterable):
    "s -> (s0,s1), (s1,s2), (s2, s3), ..."
    a, b = tee(iterable)
    next(b, None)
    return zip(a, b)

It is documented in Python doc . You can easily extend it to wider window.

Here is one way you could do it...

find . -type f -name "*_peaks.bed" | egrep -v "^(./tmp/|./scripts/)"

Using HttpClient (Http's replacement) in Angular 4.3+, the entire mapping/casting process is made simpler/eliminated.

Using your CountryData class, you would define a service method like this:

getCountries()  {
  return this.httpClient.get<CountryData[]>('http://theUrl.com/all');
}

Then when you need it, define an array like this:

countries:CountryData[] = [];

and subscribe to it like this:

this.countryService.getCountries().subscribe(countries => this.countries = countries);

A complete setup answer is posted here also.

My answer seems like less code and it works for me:

    class Nose {
      constructor() {
        this.booger = 'ready'; 
      }
      
      pick() {
        console.log('pick your nose')
      } 
    }
    
    class Ear {
      constructor() {
        this.wax = 'ready'; 
      }
      
      dig() {
        console.log('dig in your ear')
      } 
    }
    
    class Gross extends Classes([Nose,Ear]) {
      constructor() {
        super();
        this.gross = true;
      }
    }
    
    function Classes(bases) {
      class Bases {
        constructor() {
          bases.forEach(base => Object.assign(this, new base()));
        }
      }
      bases.forEach(base => {
        Object.getOwnPropertyNames(base.prototype)
        .filter(prop => prop != 'constructor')
        .forEach(prop => Bases.prototype[prop] = base.prototype[prop])
      })
      return Bases;
    }

    
    // test it
    
    var grossMan = new Gross();
    grossMan.pick(); // eww
    grossMan.dig();  // yuck!

You can overwrite the existing jenkins.war file with the new one and then restart Jenkins.

This file is usually located in /usr/share/jenkins.

If this is not the case for your system, in Manage Jenkins -> System Information, it will display the path to the .war file under executable-war.

If you don't want to use a library, this should cover most/all of the same form element types.

function serialize(form) {
  if (!form || !form.elements) return;

  var serial = [], i, j, first;
  var add = function (name, value) {
    serial.push(encodeURIComponent(name) + '=' + encodeURIComponent(value));
  }

  var elems = form.elements;
  for (i = 0; i < elems.length; i += 1, first = false) {
    if (elems[i].name.length > 0) { /* don't include unnamed elements */
      switch (elems[i].type) {
        case 'select-one': first = true;
        case 'select-multiple':
          for (j = 0; j < elems[i].options.length; j += 1)
            if (elems[i].options[j].selected) {
              add(elems[i].name, elems[i].options[j].value);
              if (first) break; /* stop searching for select-one */
            }
          break;
        case 'checkbox':
        case 'radio': if (!elems[i].checked) break; /* else continue */
        default: add(elems[i].name, elems[i].value); break;
      }
    }
  }

  return serial.join('&');
}

Doesn't sun have their own now? What's this:
http://www.java2s.com/Open-Source/Java-Document/6.0-JDK-Modules-com.sun/istack/com.sun.istack.internal.htm

This seems to be packaged with all the versions of Java I've used within the last few years.

Edit: As mentioned in the comments below, you probably don't want to use these. In that case, my vote is for the IntelliJ jetbrains annotations!

I wrote this for strings AND functionality (I know it's not the question but I searched for it and got here), maybe it can be expanded.

String.prototype.contains = function(str) {
  return this.indexOf(str) != -1;
};

String.prototype.containsAll = function(strArray) {
  for (var i = 0; i < strArray.length; i++) {
    if (!this.contains(strArray[i])) {
      return false;
    }
  }
  return true;
}

app.filter('filterMultiple', function() {
  return function(items, filterDict) {
    return items.filter(function(item) {
      for (filterKey in filterDict) {
        if (filterDict[filterKey] instanceof Array) {
          if (!item[filterKey].containsAll(filterDict[filterKey])) {
            return false;
          }
        } else {
          if (!item[filterKey].contains(filterDict[filterKey])) {
            return false;
          }
        }
      }
      return true;
    });  
  };
});

Usage:

<li ng-repeat="x in array | filterMultiple:{key1: value1, key2:[value21, value22]}">{{x.name}}</li>

xcopy  "C:\Documents and Settings\user\Desktop\?????????" "D:\Backup" /s /e /y /i

Probably the problem is the space.Try with quotes.

1. another odd testing function

Ok, the assignment was handed in 8+ years ago, but here is another solution based on bit shifting operations:

def isodd(i):
    return(bool(i>>0&1))

testing gives:

>>> isodd(2)
False
>>> isodd(3)
True
>>> isodd(4)
False

2. Nearest Odd number alternative approach

However, instead of a code that says "give me this precise input (an integer odd number) or otherwise I won't do anything" I also like robust codes that say, "give me a number, any number, and I'll give you the nearest pyramid to that number".

In that case this function is helpful, and gives you the nearest odd (e.g. any number f such that 6<=f<8 is set to 7 and so on.)

def nearodd(f):
    return int(f/2)*2+1

Example output:

nearodd(4.9)
5

nearodd(7.2)
7

nearodd(8)
9  

I think this is the best way:

this.stops.stream().filter(s -> Objects.equals(s.getStation().getName(), this.name)).findFirst().orElse(null);

Very simple example:

def loadById(self, id):
    if id in range(len(self.itemList)):
        self.load(self.itemList[id])

I can't think of a solution that does not use the range-len composition quickly.

But probably instead this should be done with try .. except to stay pythonic i guess..

The /EXCLUDE: argument expects a file containing a list of excluded files.

So create a file called excludedfileslist.txt containing:

.cs\

Then a command like this:

xcopy /r /d /i /s /y /exclude:excludedfileslist.txt C:\dev\apan C:\web\apan

Alternatively you could use Robocopy, but would require installing / copying a robocopy.exe to the machines.

Update

An anonymous comment edit which simply stated "This Solution exclude also css file!"

This is true creating a excludedfileslist.txt file contain just:

.cs

(note no backslash on the end)

Will also exclude all of the following:

• file1.cs
• file2.css
• dir1.cs\file3.txt
• dir2\anyfile.cs.something.txt

Sometimes people don't read or understand the XCOPY command's help, here is an item I would like to highlight:

Using /exclude

• List each string in a separate line in each file. If any of the listed strings match any part of the absolute path of the file to be copied, that file is then excluded from the copying process. For example, if you specify the string "\Obj\", you exclude all files underneath the Obj directory. If you specify the string ".obj", you exclude all files with the .obj extension.

As the example states it excludes "all files with the .obj extension" but it doesn't state that it also excludes files or directories named file1.obj.tmp or dir.obj.output\example2.txt.

There is a way around .css files being excluded also, change the excludedfileslist.txt file to contain just:

.cs\

(note the backslash on the end).

Here is a complete test sequence for your reference:

C:\test1>ver

Microsoft Windows [Version 6.1.7601]

5 File(s) copied

C:\test1>echo .cs > excludedfileslist.txt
C:\test1>xcopy /r /i /s /y /exclude:excludedfileslist.txt .\src .\dst
.\src\dir1\file3.txt
1 File(s) copied

C:\test1>echo .cs\ > excludedfileslist.txt

.\src\file2.css
.\src\dir1\file3.txt
.\src\dir1\file4.cs.txt
3 File(s) copied

This test was completed on a Windows 7 command line and retested on Windows 10 "10.0.14393".

Note that the last example does exclude .\src\dir2.cs\file5.txt which may or may not be unexpected for you.

I think one major reason for the bad reputation is that maven2 solves several complex problems (build automation, dependencies, managing repositories) as a one shot solution. Therefore you have to face these tough problems while starting to use maven. So it is a kind of "kill the messenger"-effect.

Other approaches (e.g. ant+ivy) often do not give you the chance to blame one single tool for all the problems you encounter. It is more like "okay ant not really easy to get started, ivy has some issues. But at least we don't have to wrestle with maven!" Saying that one does not recognize that all these problems taken together do not differ too much from the issues you encounter when using maven. It just may be a litte bit easier to tackle one at a time. BTW, I set up a build system based on ant+ivy in the past months. And I am really glad I did not have to use maven2 ;-)

Post uses the message body to send the information back to the server, as opposed to Get, which uses the query string (everything after the question mark). It is possible to send both a Get query string and a Post message body in the same request, but that can get a bit confusing so is best avoided.

Generally, best practice dictates that you use Get when you want to retrieve data, and Post when you want to alter it. (These rules aren't set in stone, the specs don't forbid altering data with Get, but it's generally avoided on the grounds that you don't want people making changes just by clicking a link or typing a URL)

Conversely, you can use Post to retrieve data without changing it, but using Get means you can bookmark the page, or share the URL with other people, things you couldn't do if you'd used Post.

• http://en.wikipedia.org/wiki/GET_%28HTTP%29
• http://en.wikipedia.org/wiki/POST_%28HTTP%29

As for the actual format of the data sent in the message body, that's entirely up to the sender and is specified with the Content-Type header. If not specified, the default content-type for HTML forms is application/x-www-form-urlencoded, which means the server will expect the post body to be a string encoded in a similar manner to a GET query string. However this can't be depended on in all cases. RFC2616 says the following on the Content-Type header:

Any HTTP/1.1 message containing an entity-body SHOULD include a
Content-Type header field defining the media type of that body. If
and only if the media type is not given by a Content-Type field, the
recipient MAY attempt to guess the media type via inspection of its
content and/or the name extension(s) of the URI used to identify the
resource. If the media type remains unknown, the recipient SHOULD
treat it as type "application/octet-stream".

i've mandained some similar page (classic asp...)

my approach was to use Q promise directly on the popup.

For example my problem was that the popup i wanted to print close itself too fast ... and the print previw was empty, i solved this way :

Caller :

var popup = window.open("index.asp","popupwindow","width=800,height=500,left=200,top=5,scrollbars,toolbar=0,resizable");

Popup (at the end of the page):

<script src="/Scripts/jquery-1.9.1.min.js"></script>
<script src="/Scripts/q.min.js"></script>
<script type="text/javascript">
    Q(window.print()).then(function () {window.close();});
</script>

I think that your "parent lock" could be solved in a similar way

i would try :

var w = whatever;
Q(
  // fill your popup
).then(function () {
 w.print();
}).then(function () {
 w.close();
}); 

that makes "the print" and "the close" async... so the parent will be immediately "unlocked"

I believe this excerpt from the Apache documentation, complements well the previous answers :

This directive is required when you use a relative path in a substitution in per-directory (htaccess) context unless either of the following conditions are true:

• The original request, and the substitution, are underneath the DocumentRoot (as opposed to reachable by other means, such as Alias).

• The filesystem path to the directory containing the RewriteRule, suffixed by the relative substitution is also valid as a URL path on the server (this is rare).

As previously mentioned, in other contexts, it is only useful to make your rule shorter. Moreover, also as previously mentioned, you can achieve the same thing by placing the htaccess file in the subdirectory.

Is there anything wrong with Nahuel Greco's solution aside from the compilation error?

If I change one line

// Compilation error
setsockopt(fd, SO_SNDTIMEO, &timeout, sizeof(timeout));

to

// Fixed?
setsockopt(fd, SOL_SOCKET, SO_SNDTIMEO, &timeout, sizeof(timeout));

then it seems to work as advertised - socket() returns a timeout error.

Resulting code:

struct timeval timeout;
timeout.tv_sec  = 7;  // after 7 seconds connect() will timeout
timeout.tv_usec = 0;
setsockopt(fd, SOL_SOCKET, SO_SNDTIMEO, &timeout, sizeof(timeout));
connect(...)

I'm not versed enough to know the tradeoffs are between a send timeout and a non-blocking socket, but I'm curious to learn.

Depending on your timezone, you may lose a few minutes (1650-01-01 00:00:00 becomes 1649-12-31 23:52:58)

Use the following code to avoid that

new Timestamp(localDateTime.getYear() - 1900, localDateTime.getMonthOfYear() - 1, localDateTime.getDayOfMonth(), localDateTime.getHourOfDay(), localDateTime.getMinuteOfHour(), localDateTime.getSecondOfMinute(), fractional);

Architecturally, System.web should not be referred in Business Logic Layer (BLL). Employ BLL into the solution structure to follow the separate of concern principle so refer System.Web is a bad practice. BLL should not load/run in Asp.net context. Because of the reason you should consider using of System.AppDomain.CurrentDomain.BaseDirectory instead of System.Web.HttpContext.Current.Server.MapPath

In a very rare case, with custom segue, the top most view controller is not in a navigation stack or tab bar controller or presented, but its view is inserted to the top of key windown's subviews.

In such situation, it's necessary to check if UIApplication.shared.keyWindow.subviews.last == self.view to determine if the current view controller is the top most.

I had the same error because i had not installed mongoDB. Make sure that you have mongodb installed and if not, you can download it from here https://www.mongodb.com/download-center/community

Even though it is about international numbers I would want the code to be like :

/^(\+|\d)[0-9]{7,16}$/;

As you can have international numbers starting with '00' as well.

Why I prefer 15 digits : http://en.wikipedia.org/wiki/E.164

Something like this will work

$('#usersSearch').keypress(function(ev){
    if (ev.which === 13)
        $('#searchButton').click();
});

Checking for the length of the string also works and is compact:

where length(stringexpression) > 0;

The most Pythonic idiom is to clearly document what the function expects and then just try to use whatever gets passed to your function and either let exceptions propagate or just catch attribute errors and raise a TypeError instead. Type-checking should be avoided as much as possible as it goes against duck-typing. Value testing can be OK – depending on the context.

The only place where validation really makes sense is at system or subsystem entry point, such as web forms, command line arguments, etc. Everywhere else, as long as your functions are properly documented, it's the caller's responsibility to pass appropriate arguments.

Say you have a DIV you want centred horizontally:

 <div id="foo">Lorem ipsum</div>

In the CSS you'd style it with this:

#foo
{
  margin:0 auto; 
  width:30%;
}

Which states that you have a top and bottom margin of zero pixels, and on either left or right, automatically work out how much is needed to be even.

Doesn't really matter what you put in for the width, as long as it's there and isn't 100%. Otherwise you wouldn't be setting the centre on anything.

But if you float it, left or right, then the bets are off since that pulls it out of the normal flow of elements on the page and the auto margin setting won't work.

You forgot the () at the end. It is not a variable, but a function and when there are not parameters, you still need the () at the end.

For future coding practices, I would highly recommend reforming the code a little bit as this can become frustrating to read:

 public string LastName
 { get { return lastName; } set { lastName = value; } }

If there is any kind of processing which happens in here (thankfully doesn't happen here), it will become very confusing. If you're going to pass your code onto someone else, I would recommend:

public string LastName
{
  get
  {
     return lastName;
  }
  set
  {
     lastName = value;
  }
}

It's a lot longer, but it's much easier to read when glancing at a huge section of code.

You can listen resize event and fire where some dimension change

directive

(function() {
'use strict';

    angular
    .module('myApp.directives')
    .directive('resize', ['$window', function ($window) {
        return {
            link: link,
            restrict: 'A'
        };

        function link(scope, element, attrs){
            scope.width = $window.innerWidth;
            function onResize(){
                // uncomment for only fire when $window.innerWidth change   
                // if (scope.width !== $window.innerWidth)
                {
                    scope.width = $window.innerWidth;
                    scope.$digest();
                }
            };

            function cleanUp() {
                angular.element($window).off('resize', onResize);
            }

            angular.element($window).on('resize', onResize);
            scope.$on('$destroy', cleanUp);
        }
    }]);
})();

In html

<div class="row" resize> ,
    <div class="col-sm-2 col-xs-6" ng-repeat="v in tag.vod"> 
        <h4 ng-bind="::v.known_as"></h4>
    </div> 
</div> 

Controller :

$scope.$watch('width', function(old, newv){
     console.log(old, newv);
 })

There is probably a more efficient solution to your question, but following formula should do the trick:

=SUM(COUNTIFS(J1:J196,"agree",A1:A196,"yes"),COUNTIFS(J1:J196,"agree",A1:A196,"no"))

<?php
    header("Location: index.html");
?>

Just make sure nothing is actually written to the page prior to this code, or it won't work.

There is an easy way without the need to use an external tool - it runs fine with Windows 7, 8, 8.1 and 10 and is backwards-compatible too (Windows XP doesn't have any UAC, thus elevation is not needed - in that case the script just proceeds).

Check out this code (I was inspired by the code by NIronwolf posted in the thread Batch File - "Access Denied" On Windows 7?), but I've improved it - in my version there isn't any directory created and removed to check for administrator privileges):

 ECHO %batchName% Arguments: P1=%1 P2=%2 P3=%3 P4=%4 P5=%5 P6=%6 P7=%7 P8=%8 P9=%9
 cmd /k

The script takes advantage of the fact that NET FILE requires administrator privilege and returns errorlevel 1 if you don't have it. The elevation is achieved by creating a script which re-launches the batch file to obtain privileges. This causes Windows to present the UAC dialog and asks you for the administrator account and password.

I have tested it with Windows 7, 8, 8.1, 10 and with Windows XP - it works fine for all. The advantage is, after the start point you can place anything that requires system administrator privileges, for example, if you intend to re-install and re-run a Windows service for debugging purposes (assumed that mypackage.msi is a service installer package):

msiexec /passive /x mypackage.msi
msiexec /passive /i mypackage.msi
net start myservice

Without this privilege elevating script, UAC would ask you three times for your administrator user and password - now you're asked only once at the beginning, and only if required.

If your script just needs to show an error message and exit if there aren't any administrator privileges instead of auto-elevating, this is even simpler: You can achieve this by adding the following at the beginning of your script:

@ECHO OFF & CLS & ECHO.
NET FILE 1>NUL 2>NUL & IF ERRORLEVEL 1 (ECHO You must right-click and select &
  ECHO "RUN AS ADMINISTRATOR"  to run this batch. Exiting... & ECHO. &
  PAUSE & EXIT /D)
REM ... proceed here with admin rights ...

This way, the user has to right-click and select "Run as administrator". The script will proceed after the REM statement if it detects administrator rights, otherwise exit with an error. If you don't require the PAUSE, just remove it. Important: NET FILE [...] EXIT /D) must be on the same line. It is displayed here in multiple lines for better readability!

On some machines, I've encountered issues, which are solved in the new version above already. One was due to different double quote handling, and the other issue was due to the fact that UAC was disabled (set to lowest level) on a Windows 7 machine, hence the script calls itself again and again.

I have fixed this now by stripping the quotes in the path and re-adding them later, and I've added an extra parameter which is added when the script re-launches with elevated rights.

The double quotes are removed by the following (details are here):

setlocal DisableDelayedExpansion
set "batchPath=%~0"
setlocal EnableDelayedExpansion

You can then access the path by using !batchPath!. It doesn't contain any double quotes, so it is safe to say "!batchPath!" later in the script.

The line

if '%1'=='ELEV' (shift & goto gotPrivileges)

checks if the script has already been called by the VBScript script to elevate rights, hence avoiding endless recursions. It removes the parameter using shift.

Update:

• To avoid having to register the .vbs extension in Windows 10, I have replaced the line
  "%temp%\OEgetPrivileges.vbs"
  by
  "%SystemRoot%\System32\WScript.exe" "%temp%\OEgetPrivileges.vbs"
  in the script above; also added cd /d %~dp0 as suggested by Stephen (separate answer) and by Tomáš Zato (comment) to set script directory as default.

• Now the script honors command line parameters being passed to it. Thanks to jxmallet, TanisDLJ and Peter Mortensen for observations and inspirations.

• According to Artjom B.'s hint, I analyzed it and have replaced SHIFT by SHIFT /1, which preserves the file name for the %0 parameter

• Added del "%temp%\OEgetPrivileges_%batchName%.vbs" to the :gotPrivileges section to clean up (as mlt suggested). Added %batchName% to avoid impact if you run different batches in parallel. Note that you need to use for to be able to take advantage of the advanced string functions, such as %%~nk, which extracts just the filename.

• Optimized script structure, improvements (added variable vbsGetPrivileges which is now referenced everywhere allowing to change the path or name of the file easily, only delete .vbs file if batch needed to be elevated)

• In some cases, a different calling syntax was required for elevation. If the script does not work, check the following parameters:
  set cmdInvoke=0
set winSysFolder=System32
  Either change the 1st parameter to set cmdInvoke=1 and check if that already fixes the issue. It will add cmd.exe to the script performing the elevation.
  Or try to change the 2nd parameter to winSysFolder=Sysnative, this might help (but is in most cases not required) on 64 bit systems. (ADBailey has reported this). "Sysnative" is only required for launching 64-bit applications from a 32-bit script host (e.g. a Visual Studio build process, or script invocation from another 32-bit application).

• To make it more clear how the parameters are interpreted, I am displaying it now like P1=value1 P2=value2 ... P9=value9. This is especially useful if you need to enclose parameters like paths in double quotes, e.g. "C:\Program Files".

• If you want to debug the VBS script, you can add the //X parameter to WScript.exe as first parameter, as suggested here (it is described for CScript.exe, but works for WScript.exe too).

You could just:

print(foo[randint(0,4)])

A more detailed answer for dummies like me:

1. Open the SDK manager
2. Select the SDK Tools tab.
3. Download – Make sure that intel x86 Emulator Accelerator (HAXM) is downloaded.
4. Install – Now that HAXM is downloaded, make sure it is installed. In the SDK window it will show you where the SDK is located on your computer: Click/tap 3 times quickly to highlight this text and copy the folder location. Open the file explorer and paste in the file location. From here you can search “hax” to find the folder location for HAXM stuff. Once a file comes up in the search results, right click and select “open file location”. For me the location was C:\Users\Datu1\AppData\Local\Android\Sdk\extras\intel\Hardware_Accelerated_Execution_Manager . Find the file intelhaxm-android.exe and open/run it. Follow the instructions when it runs. You may wish to run haxm_check as an administrator (it’s in this same folder), but it may or may not work for you. The surefire way to tell if you can run hardware acceleration and if it’s enabled is to go to your computer’s bios settings from the startup menu.

5. BIOS settings – Make sure hardware acceleration is enabled in your BIOS settings. The way to do this may vary a bit from system to system. You may need to press f10 or esc on startup. But with most (updated) Windows 10 computers you can access the BIOS settings by doing the following: type “advanced startup” in the Windows search bar; click on “change advanced startup uptions:” when it comes up. Click “Restart now”. After your computer restarts click on Troubleshoot. Click advanced options >firmware settings, then restart to change EUFI firmware settings. Wait for the restart then select the menu option for bios settings. With Intel processors the steps will be as follows or similar: Press the right arrow to go to the Configuration tab. Arrow down to Intel Virtual/Virtualizaion Technology and turn it on (should say Enabled). Exit and save changes.

6. If Virtual Technology was previously disabled in your bios settings You will need to run the intelhaxm-android.exe file now to install haxm.

7. Try restarting Android Studio and running your emulator again. If it’s still not working, restart your computer and try again, it should work.

NOTE: if you have Windows Hyper-V turned on this will cause you to not be able to run haxm. If you are having an issue with Hyper-V, make sure it is turned off in your settings: search in the Windows bar for “hyper”; the search result should take you to “Turn Windows features on or off”. Then make sure all the Hyper-V boxes are unchecked.

That's a lot of questions.

1. Why EOF is -1: usually -1 in POSIX system calls is returned on error, so i guess the idea is "EOF is kind of error"

2. any boolean operation (including !=) returns 1 in case it's TRUE, and 0 in case it's FALSE, so getchar() != EOF is 0 when it's FALSE, meaning getchar() returned EOF.

3. in order to emulate EOF when reading from stdin press Ctrl+D

Instead of defining: COLUMN_HEADINGS("columnHeadings")

Try defining it as: COLUMNHEADINGS("columnHeadings")

Then when you call getByName(String name) method, call it with the upper-cased String like this: getByName(myStringVariable.toUpperCase())

I had the same problem as you, and this worked for me.

This is most likely because the IIS user doesn't have access to the private key for your certificate. You can set this by following these steps...

1. Start ? Run ? MMC
2. File ? Add/Remove Snapin
3. Add the Certificates Snap In
4. Select Computer Account, then hit next
5. Select Local Computer (the default), then click Finish
6. On the left panel from Console Root, navigate to Certificates (Local Computer) ? Personal ? Certificates
7. Your certificate will most likely be here.
8. Right click on your certificate ? All Tasks ? Manage Private Keys
9. Set your private key settings here.

See the mysql manual, Unicode Character Sets section:

For any Unicode character set, operations performed using the _general_ci collation are faster than those for the _unicode_ci collation. For example, comparisons for the utf8_general_ci collation are faster, but slightly less correct, than comparisons for utf8_unicode_ci. The reason for this is that utf8_unicode_ci supports mappings such as expansions; that is, when one character compares as equal to combinations of other characters. For example, in German and some other languages “ß” is equal to “ss”. utf8_unicode_ci also supports contractions and ignorable characters. utf8_general_ci is a legacy collation that does not support expansions, contractions, or ignorable characters. It can make only one-to-one comparisons between characters.

So to summarize, utf_general_ci uses a smaller and less correct (according to the standard) set of comparisons than utf_unicode_ci which should implement the entire standard. The general_ci set will be faster because there is less computation to do.

HTTP doesn't support redirection to a page using POST. When you redirect somewhere, the HTTP "Location" header tells the browser where to go, and the browser makes a GET request for that page. You'll probably have to just write the code for your page to accept GET requests as well as POST requests.

The reason for using dictionaries in the first place is performance. Although it is correct that you can use named vectors and lists for the task the issue is that they are becoming quite slow and memory hungry with more data.

Yet what many people don't know is that R has indeed an inbuilt dictionary data structure: environments with the option hash = TRUE

See the following example for how to make it work:

# vectorize assign, get and exists for convenience
assign_hash <- Vectorize(assign, vectorize.args = c("x", "value"))
get_hash <- Vectorize(get, vectorize.args = "x")
exists_hash <- Vectorize(exists, vectorize.args = "x")

# keys and values
key<- c("tic", "tac", "toe")
value <- c(1, 22, 333)

# initialize hash
hash = new.env(hash = TRUE, parent = emptyenv(), size = 100L)
# assign values to keys
assign_hash(key, value, hash)
## tic tac toe 
##   1  22 333
# get values for keys
get_hash(c("toe", "tic"), hash)
## toe tic 
## 333   1
# alternatively:
mget(c("toe", "tic"), hash)
## $toe
## [1] 333
## 
## $tic
## [1] 1
# show all keys
ls(hash)
## [1] "tac" "tic" "toe"
# show all keys with values
get_hash(ls(hash), hash)
## tac tic toe 
##  22   1 333
# remove key-value pairs
rm(list = c("toe", "tic"), envir = hash)
get_hash(ls(hash), hash)
## tac 
##  22
# check if keys are in hash
exists_hash(c("tac", "nothere"), hash)
##     tac nothere 
##    TRUE   FALSE
# for single keys this is also possible:
# show value for single key
hash[["tac"]]
## [1] 22
# create new key-value pair
hash[["test"]] <- 1234
get_hash(ls(hash), hash)
##  tac test 
##   22 1234
# update single value
hash[["test"]] <- 54321
get_hash(ls(hash), hash)
##   tac  test 
##    22 54321

Edit: On the basis of this answer I wrote a blog post with some more context: http://blog.ephorie.de/hash-me-if-you-can

a = np.subtract(a, 0., dtype=np.float32)

If you use eclipse (Eclipse can put utf8 code for you even you write utf8 character. You will see normal utf8 character when you programming but background will be utf8 code) ;

1. Select Project
2. Right click and select Properties
3. Select Resource on Resource Panel(Top of right menu which opened after 2.)
4. You can see in Resource Panel, Text File Encoding, select other which you want

P.S : this will ok if you static value in code. For Example String test = "IIIIIiiiiiiççççç";

Double parenthesis (( ... )) is used for arithmetic operations.

Double square brackets [[ ... ]] can be used to compare and examine numbers (only integers are supported), with the following operators:

· NUM1 -eq NUM2 returns true if NUM1 and NUM2 are numerically equal.

· NUM1 -ne NUM2 returns true if NUM1 and NUM2 are not numerically equal.

· NUM1 -gt NUM2 returns true if NUM1 is greater than NUM2.

· NUM1 -ge NUM2 returns true if NUM1 is greater than or equal to NUM2.

· NUM1 -lt NUM2 returns true if NUM1 is less than NUM2.

· NUM1 -le NUM2 returns true if NUM1 is less than or equal to NUM2.

For example

if [[ $age > 21 ]] # bad, > is a string comparison operator

if [ $age > 21 ] # bad, > is a redirection operator

if [[ $age -gt 21 ]] # okay, but fails if $age is not numeric

if (( $age > 21 )) # best, $ on age is optional

This one always keeps the right frame:

I can offer you a jquery solution

add this in your <head></head> tag

<script type="text/javascript" src="http://code.jquery.com/jquery-1.10.2.min.js"></script>

add this after </ul>

 <script> $('ul li:first').remove(); </script> 

Your problems have nothing to do with POST/GET but only with how you specify parameters in RouteAttribute. To ensure this, I added support for both verbs in my samples.

Let's go back to two very simple working examples.

[Route("api/deliveryitems/{anyString}")]
[HttpGet, HttpPost]
public HttpResponseMessage GetDeliveryItemsOne(string anyString)
{
    return Request.CreateResponse<string>(HttpStatusCode.OK, anyString);
}

And

[Route("api/deliveryitems")]
[HttpGet, HttpPost]
public HttpResponseMessage GetDeliveryItemsTwo(string anyString = "default")
{
    return Request.CreateResponse<string>(HttpStatusCode.OK, anyString);
}

The first sample says that the "anyString" is a path segment parameter (part of the URL).

First sample example URL is:

• localhost:xxx/api/deliveryItems/dkjd;dslkf;dfk;kkklm;oeop
  • returns "dkjd;dslkf;dfk;kkklm;oeop"

The second sample says that the "anyString" is a query string parameter (optional here since a default value has been provided, but you can make it non-optional by simply removing the default value).

Second sample examples URL are:

• localhost:xxx/api/deliveryItems?anyString=dkjd;dslkf;dfk;kkklm;oeop
  • returns "dkjd;dslkf;dfk;kkklm;oeop"
• localhost:xxx/api/deliveryItems
  • returns "default"

Of course, you can make it even more complex, like with this third sample:

[Route("api/deliveryitems")]
[HttpGet, HttpPost]
public HttpResponseMessage GetDeliveryItemsThree(string anyString, string anotherString = "anotherDefault")
{
    return Request.CreateResponse<string>(HttpStatusCode.OK, anyString + "||" + anotherString);
}

Third sample examples URL are:

• localhost:xxx/api/deliveryItems?anyString=dkjd;dslkf;dfk;kkklm;oeop
  • returns "dkjd;dslkf;dfk;kkklm;oeop||anotherDefault"
• localhost:xxx/api/deliveryItems
  • returns "No HTTP resource was found that matches the request URI ..." (parameter anyString is mandatory)
• localhost:xxx/api/deliveryItems?anotherString=bluberb&anyString=dkjd;dslkf;dfk;kkklm;oeop
  • returns "dkjd;dslkf;dfk;kkklm;oeop||bluberb"
  • note that the parameters have been reversed, which does not matter, this is not possible with "URL-style" of first example

When should you use path segment or query parameters? Some advice has already been given here: REST API Best practices: Where to put parameters?

this also works, and prolly is more readable than the echo version:

printf "`date` User `whoami` started the script.\r\n" >> output.log

None of the above answers worked for me but this does -- Use <P style='line-height: 8px;'> to replace <p> wherever needed (or put it in the style tag like <style>P {line-height: 8px;}</style> to affect all <p> tags). I realise Mauro says this, but if someone comes here for help, I expect they would want to see an example.

You can just use .animate() the scrollTop property, like this:

$("html, body").animate({ scrollTop: "300px" });

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical"
    android:padding="20dp" >

    <TextView
        android:id="@+id/textview"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center_horizontal"
        android:shadowColor="#000"
        android:shadowDx="0"
        android:shadowDy="0"
        android:shadowRadius="50"
        android:text="Text Shadow Example1"
        android:textColor="#FBFBFB"
        android:textSize="28dp"
        android:textStyle="bold" />

    <TextView
        android:id="@+id/textview2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center_horizontal"
        android:text="Text Shadow Example2"
        android:textColor="#FBFBFB"
        android:textSize="28dp"
        android:textStyle="bold" />

</LinearLayout>

In the above XML layout code, the textview1 is given with Shadow effect in the layout. below are the configuration items are

android:shadowDx – specifies the X-axis offset of shadow. You can give -/+ values, where -Dx draws a shadow on the left of text and +Dx on the right

android:shadowDy – it specifies the Y-axis offset of shadow. -Dy specifies a shadow above the text and +Dy specifies below the text.

android:shadowRadius – specifies how much the shadow should be blurred at the edges. Provide a small value if shadow needs to be prominent. android:shadowColor – specifies the shadow color

Shadow Effect on Android TextView pragmatically

Use below code snippet to get the shadow effect on the second TextView pragmatically.

TextView textv = (TextView) findViewById(R.id.textview2);
textv.setShadowLayer(30, 0, 0, Color.RED);        

Output :

Use \t to add tab and \n for new line, here is a simple example below.

<string name="list_with_tab_tag">\tbanana\torange\tblueberry\tmango</string>
<string name="sentence_with_new_line_tag">This is the first sentence\nThis is the second scentence\nThis is the third sentence</string>

Much simpler using only SimpleDateFormat, without passing all the parameters individual:

    String FORMATER = "yyyy-MM-dd'T'HH:mm:ss'Z'";

    DateFormat format = new SimpleDateFormat(FORMATER);

    Date date = new Date();
    XMLGregorianCalendar gDateFormatted =
        DatatypeFactory.newInstance().newXMLGregorianCalendar(format.format(date));

Full example here.

Note: This is working only to remove the last 2 fields: milliseconds and timezone or to remove the entire time component using formatter yyyy-MM-dd.

This library adds a desiredAccuracy and maxWait option to geolocation calls, which means it will keep trying to get a position until the accuracy is within a specified range.

You can't determine the amount of data in a stream without reading it; you can, however, ask for the size of a file:

http://java.sun.com/javase/6/docs/api/java/io/File.html#length()

If that isn't possible, you can write the bytes you read from the input stream to a ByteArrayOutputStream which will grow as required.

You can use this code:

STR(<Your Field>, Length, Scale)

Your Field = Float field for convert

Length = Total length of your float number with Decimal point

Scale = Number of length after decimal point

For Example:

SELECT STR(1234.5678912,8,3)

Result is: 1234.568

Note that the last digit is also round up.

Good luck.

if faceing that error like geocoding access denied : so you can enable geocoding api service from getKey account.enter image description here

Super easy with flexbox. Leave room for some space by changing the columns to col-md-5

<div class="row widgets">
    <div class="text-center col-md-5">
        Widget 1
    </div>
    <div class="text-center col-md-5">
        Widget 2

    justify-content: space-around;
}

The class Doctrine\ORM\EntityRepository implements Doctrine\Common\Collections\Selectable API.

The Selectable interface is very flexible and quite new, but it will allow you to handle comparisons and more complex criteria easily on both repositories and single collections of items, regardless if in ORM or ODM or completely separate problems.

This would be a comparison criteria as you just requested as in Doctrine ORM 2.3.2:

$criteria = new \Doctrine\Common\Collections\Criteria();
$criteria->where($criteria->expr()->gt('prize', 200));

$result = $entityRepository->matching($criteria);

The major advantage in this API is that you are implementing some sort of strategy pattern here, and it works with repositories, collections, lazy collections and everywhere the Selectable API is implemented.

This allows you to get rid of dozens of special methods you wrote for your repositories (like findOneBySomethingWithParticularRule), and instead focus on writing your own criteria classes, each representing one of these particular filters.

That's the "forall" (for all) symbol, as seen in Wikipedia's table of mathematical symbols or the Unicode forall character (\u2200, ?).

Big-O is to little-o as = is to <. Big-O is an inclusive upper bound, while little-o is a strict upper bound.

For example, the function f(n) = 3n is:

• in O(n²), o(n²), and O(n)
• not in O(lg n), o(lg n), or o(n)

Analogously, the number 1 is:

• = 2, < 2, and = 1
• not = 0, < 0, or < 1

Here's a table, showing the general idea:

(Note: the table is a good guide but its limit definition should be in terms of the superior limit instead of the normal limit. For example, 3 + (n mod 2) oscillates between 3 and 4 forever. It's in O(1) despite not having a normal limit, because it still has a lim sup: 4.)

I recommend memorizing how the Big-O notation converts to asymptotic comparisons. The comparisons are easier to remember, but less flexible because you can't say things like n^O(1) = P.

Test Data

DECLARE @Table1 TABLE(ID INT, Value INT)
INSERT INTO @Table1 VALUES (1,100),(1,200),(1,300),(1,400)

Query

SELECT  ID
       ,STUFF((SELECT ', ' + CAST(Value AS VARCHAR(10)) [text()]
         FROM @Table1 
         WHERE ID = t.ID
         FOR XML PATH(''), TYPE)
        .value('.','NVARCHAR(MAX)'),1,2,' ') List_Output
FROM @Table1 t
GROUP BY ID

Result Set

+--------------------------+
¦ ID ¦     List_Output     ¦
¦----+---------------------¦
¦  1 ¦  100, 200, 300, 400 ¦
+--------------------------+

SQL Server 2017 and Later Versions

If you are working on SQL Server 2017 or later versions, you can use built-in SQL Server Function STRING_AGG to create the comma delimited list:

DECLARE @Table1 TABLE(ID INT, Value INT);
INSERT INTO @Table1 VALUES (1,100),(1,200),(1,300),(1,400);


SELECT ID , STRING_AGG([Value], ', ') AS List_Output
FROM @Table1
GROUP BY ID;

Result Set

+--------------------------+
¦ ID ¦     List_Output     ¦
¦----+---------------------¦
¦  1 ¦  100, 200, 300, 400 ¦
+--------------------------+

you can use Array.select or Array.index to do that.

<div id="video_box">
  <div id="video_overlays"></div>
  <div>
    <video id="player" src="http://video.webmfiles.org/big-buck-bunny_trailer.webm" type="video/webm" onclick="this.play();">Your browser does not support this streaming content.</video>
  </div>
</div>

for this you need to just add css like this:

#video_overlays {
  position: absolute;
  background-color: rgba(0, 0, 0, 0.46);
  z-index: 2;
  left: 0;
  right: 0;
  top: 0;
  bottom: 0;
}
#video_box{position: relative;}

I needed to import javaee-api as well.

  <dependency>
     <groupId>javax</groupId>
     <artifactId>javaee-api</artifactId>
     <version>7.0</version>
  </dependency>

Unless I got following error:

package javax.servlet.http does not exist
javax.servlet.annotation does not exist
javax.servlet.http does not exist
...

I had the same problem with a folder full of temporary images that was growing day by day and this command helped me to clear the folder

find . -name "*.png" -mtime +50 -exec rm {} \;

The difference with the other commands is the mtime parameter that will take only the files older than X days (in the example 50 days)

Using that multiple times, decreasing on every execution the day range, I was able to remove all the unnecessary files

You could try:

List<ManagementObject> managementList = new List<ManagementObject>(managementObjects.ToArray());

Not sure if .ToArray() is available for the collection. If you do use the code you posted, make sure you initialize the List with the number of existing elements:

List<ManagementObject> managementList = new List<ManagementObject>(managementObjects.Count);  // or .Length

After searching for an hour or two ,I've found a simple solution below.

const date = new Date(`${date from client} GMT`);

inside double ticks, there is a date from client side plust GMT.

I'm first time commenting, constructive criticism will be welcomed.

Here is one to sort various columns in a csv file by numeric and dictionary order, columns 5 and after as dictionary order

~/test>sort -t, -k1,1n -k2,2n -k3,3d -k4,4n -k5d  sort.csv
1,10,b,22,Ga
2,2,b,20,F
2,2,b,22,Ga
2,2,c,19,Ga
2,2,c,19,Gb,hi
2,2,c,19,Gb,hj
2,3,a,9,C

~/test>cat sort.csv
2,3,a,9,C
2,2,b,20,F
2,2,c,19,Gb,hj
2,2,c,19,Gb,hi
2,2,c,19,Ga
2,2,b,22,Ga
1,10,b,22,Ga

Note the -k1,1n means numeric starting at column 1 and ending at column 1. If I had done below, it would have concatenated column 1 and 2 making 1,10 sorted as 110

~/test>sort -t, -k1,2n -k3,3 -k4,4n -k5d  sort.csv
2,2,b,20,F
2,2,b,22,Ga
2,2,c,19,Ga
2,2,c,19,Gb,hi
2,2,c,19,Gb,hj
2,3,a,9,C
1,10,b,22,Ga

Year(Date)

Year(): Returns the year portion of the date argument.
Date: Current date only.

In answer to your second question: Yes a HashMap can hold different types of objects. Whether that's a good idea or not depends on the problem you're trying to solve.

That said, your example won't work. The int value is not an Object. You have to use the Integer wrapper class to store an int value in a HashMap

For the record, I am testing two codes: That simply try to convert from a string to a number and if it fail then assign number to zero.

        if (!Int32.TryParse(txt,out tmpint)) {
            tmpint = 0;
        }

and:

        try {
            tmpint = Convert.ToInt32(txt);
        } catch (Exception) {
            tmpint = 0;
        }

For c#, the best option is to use tryparse because try&Catch alternative thrown the exception

A first chance exception of type 'System.FormatException' occurred in mscorlib.dll

That it is painful slow and undesirable, however, the code does not stop unless Debug's exception are settled for stop with it.

<script type="text/javascript">
     $(document).ready(function() {
     var asdf = $('.capsf').text();

    $('.capsf').text(asdf.toLowerCase());
     });
     </script>
<div style="text-transform: capitalize;"  class="capsf">sd GJHGJ GJHgjh gh hghhjk ku</div>

Due to the nature of <img> being a replaced element, document styling doesn’t affected it.

To reference it anyway, <picture> provides an ideal, native wrapper that can have pseudo-elements attached to it, like so:

img:after, picture:after{_x000D_
    content:"\1F63B";_x000D_
    font-size:larger;_x000D_
    margin:-1em;_x000D_
}

<img src="//placekitten.com/110/80">_x000D_
_x000D_
<picture>_x000D_
    <img src="//placekitten.com/110/80">_x000D_
</picture>

In my case the error was caused by the insufficient memory allocated to the "test" lifecycle of maven. It was fixed by adding <argLine>-Xms3512m -Xmx3512m</argLine> to:

<pluginManagement>
  <plugins>
    <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-surefire-plugin</artifactId>
        <version>2.16</version>
        <configuration>
            <argLine>-Xms3512m -Xmx3512m</argLine>

Thanks @crazycoder for pointing this out (and also that it is not related to IntelliJ; in this case).

If your tests are forked, they run in a new JVM that doesn't inherit Maven JVM options. Custom memory options must be provided via the test runner in pom.xml, refer to Maven documentation for details, it has very little to do with the IDE.

Ok If I understand what your asking you would do this;

You have your DIV container called #main-container and .my-element that is within it. Use this to get you started;

#main-container { 
  position:relative;
}
/*To make the element absolute - floats above all else within the parent container do this.*/
.my-element {
  position:absolute;
  top:0;
  right:10px;
}

/*To make the element apart of elements, something tangible that affects the position of other elements on the same level within the parent then do this;*/
.my-element {
  float:right;
  margin-right:10px;
}

By the way, it better practice to use classes if you referencing a lower level element within a page (I assume you are hence my name change above.

int main(){
.... example with file
     //input is a file
    if(input.is_open()){
        cin.ignore(1,'\n'); //it ignores everything after new line
        cin.getline(buffer,255); // save it in buffer
        input<<buffer; //save it in input(it's a file)
        input.close();
    }
}

The raw_json_encode() function above did not solve me the problem (for some reason, the callback function raised an error on my PHP 5.2.5 server).

But this other solution did actually work.

https://www.experts-exchange.com/questions/28628085/json-encode-fails-with-special-characters.html

Credits should go to Marco Gasi. I just call his function instead of calling json_encode():

function jsonRemoveUnicodeSequences( $json_struct )
{ 
    return preg_replace( "/\\\\u([a-f0-9]{4})/e", "iconv('UCS-4LE','UTF-8',pack('V', hexdec('U$1')))", json_encode( $json_struct ) );
}

You could add android:textAllCaps="false" to the button.

The button text might be transformed to uppercase by your app's theme that applies to all buttons. Check themes / styles files for setting the attribute android:textAllCaps.

Filename=url.java

public class url {

    public static final String BASEURL = "http://192.168.1.122/";

}

if u want to call the variable just use this:

url.BASEURL + "your code here";

Since my initial answer was criticised on the basis that my special-purpose constructors did not call the (unique) default constructor, I post here a modified version that honours the wishes that all constructors shall call the default one:

class Cheese:
    def __init__(self, *args, _initialiser="_default_init", **kwargs):
        """A multi-initialiser.
        """
        getattr(self, _initialiser)(*args, **kwargs)

    def _default_init(self, ...):
        """A user-friendly smart or general-purpose initialiser.
        """
        ...

    def _init_parmesan(self, ...):
        """A special initialiser for Parmesan cheese.
        """
        ...

    def _init_gouda(self, ...):
        """A special initialiser for Gouda cheese.
        """
        ...

    @classmethod
    def make_parmesan(cls, *args, **kwargs):
        return cls(*args, **kwargs, _initialiser="_init_parmesan")

    @classmethod
    def make_gouda(cls, *args, **kwargs):
        return cls(*args, **kwargs, _initialiser="_init_gouda")

By default, Xcode sets the bundle identifier to the bundle/company identifier that you set during project creation + project name.

This is similar to what you see in the Project > Summary screen.

But you can change this in the Project > Info screen. (This is the Info.plist.)

You can use .is(':visible') to test if something is visible and .is(':hidden') to test for the opposite:

$('#offers').toggle(!$('#column-left form').is(':visible')); // or:
$('#offers').toggle($('#column-left form').is(':hidden'));

Track the remote branch

You can specify the default remote repository for pushing and pulling using git-branch’s track option. You’d normally do this by specifying the --track option when creating your local master branch, but as it already exists we’ll just update the config manually like so:

Edit your .git/config

[branch "master"]
  remote = origin
  merge = refs/heads/master

Now you can simply git push and git pull.

One can use runner package for moving functions. In this case mean_run function. Problem with cummean is that it doesn't handle NA values, but mean_run does. runner package also supports irregular time series and windows can depend on date:

library(runner)
set.seed(11)
x1 <- rnorm(15)
x2 <- sample(c(rep(NA,5), rnorm(15)), 15, replace = TRUE)
date <- Sys.Date() + cumsum(sample(1:3, 15, replace = TRUE))

One can also specify other options like lag, and roll only at specific indexes. More in package and function documentation.

You create the array each time and add a value to it ... its working as expected ?

Moving the array outside of the live() function works fine :

var myarray = []; // more efficient than new Array()
$("#test").live("click",function() {
        myarray.push($("#drop").val());
        alert(myarray);
});

http://jsfiddle.net/dKWnb/5/

Also note that in later versions of jQuery v1.7 -> the live() method is deprecated and replaced by the on() method.

My solution was to change the name of my signing config from the default "config" to "debug". To verify, I changed it to some other random name and got the error again, and then changed it back to "debug" and the error was gone. So while it seems artificial and I tend to not believe this is the whole story, give this solution a try.

please Press fn +ins key together

Don't forget the easy route:

    static void Main(string[] args)
    {
        var text = File.ReadAllText(@"C:\words.txt");
        File.WriteAllText(@"C:\words.txt", text + "DERP");
    }

You didn't mention the fancy indexing capabilities of dataframes, e.g.:

>>> df = pd.DataFrame({"class":[1,1,1,2,2], "value":[1,2,3,4,5]})
>>> df[df["class"]==1].sum()
class    3
value    6
dtype: int64
>>> df[df["class"]==1].sum()["value"]
6
>>> df[df["class"]==1].count()["value"]
3

You could replace df["class"]==1by another condition.

Version 1.18 of Lombok introduced the @SuperBuilder annotation. We can use this to solve our problem in a simpler way.

You can refer to https://www.baeldung.com/lombok-builder-inheritance#lombok-builder-and-inheritance-3.

so in your child class, you will need these annotations:

@Data
@SuperBuilder
@NoArgsConstructor
@EqualsAndHashCode(callSuper = true)

in your parent class:

@Data
@SuperBuilder
@NoArgsConstructor

You can catch it like any other exception:

try {
  foo();
}
catch (const std::bad_alloc&) {
  return -1;
}

Quite what you can usefully do from this point is up to you, but it's definitely feasible technically.

In general you cannot, and should not try, to respond to this error. bad_alloc indicates that a resource cannot be allocated because not enough memory is available. In most scenarios your program cannot hope to cope with that, and terminating soon is the only meaningful behaviour.

Worse, modern operating systems often over-allocate: on such systems, malloc and new can return a valid pointer even if there is not enough free memory left – std::bad_alloc will never be thrown, or is at least not a reliable sign of memory exhaustion. Instead, attempts to access the allocated memory will then result in a segmentation fault, which is not catchable (you can handle the segmentation fault signal, but you cannot resume the program afterwards).

The only thing you could do when catching std::bad_alloc is to perhaps log the error, and try to ensure a safe program termination by freeing outstanding resources (but this is done automatically in the normal course of stack unwinding after the error gets thrown if the program uses RAII appropriately).

In certain cases, the program may attempt to free some memory and try again, or use secondary memory (= disk) instead of RAM but these opportunities only exist in very specific scenarios with strict conditions:

1. The application must ensure that it runs on a system that does not overcommit memory, i.e. it signals failure upon allocation rather than later.
2. The application must be able to free memory immediately, without any further accidental allocations in the meantime.

It’s exceedingly rare that applications have control over point 1 — userspace applications never do, it’s a system-wide setting that requires root permissions to change.¹

OK, so let’s assume you’ve fixed point 1. What you can now do is for instance use a LRU cache for some of your data (probably some particularly large business objects that can be regenerated or reloaded on demand). Next, you need to put the actual logic that may fail into a function that supports retry — in other words, if it gets aborted, you can just relaunch it:

lru_cache<widget> widget_cache;

double perform_operation(int widget_id) {
    std::optional<widget> maybe_widget = widget_cache.find_by_id(widget_id);
    if (not maybe_widget) {
        maybe_widget = widget_cache.store(widget_id, load_widget_from_disk(widget_id));
    }
    return maybe_widget->frobnicate();
}

…

for (int num_attempts = 0; num_attempts < MAX_NUM_ATTEMPTS; ++num_attempts) {
    try {
        return perform_operation(widget_id);
    } catch (std::bad_alloc const&) {
        if (widget_cache.empty()) throw; // memory error elsewhere.
        widget_cache.remove_oldest();
    }
}

// Handle too many failed attempts here.

But even here, using std::set_new_handler instead of handling std::bad_alloc provides the same benefit and would be much simpler.

¹ If you’re creating an application that does control point 1, and you’re reading this answer, please shoot me an email, I’m genuinely curious about your circumstances.

What is the C++ Standard specified behavior of new in c++?

The usual notion is that if new operator cannot allocate dynamic memory of the requested size, then it should throw an exception of type std::bad_alloc.
However, something more happens even before a bad_alloc exception is thrown:

C++03 Section 3.7.4.1.3: says

An allocation function that fails to allocate storage can invoke the currently installed new_handler(18.4.2.2), if any. [Note: A program-supplied allocation function can obtain the address of the currently installed new_handler using the set_new_handler function (18.4.2.3).] If an allocation function declared with an empty exception-specification (15.4), throw(), fails to allocate storage, it shall return a null pointer. Any other allocation function that fails to allocate storage shall only indicate failure by throw-ing an exception of class std::bad_alloc (18.4.2.1) or a class derived from std::bad_alloc.

Consider the following code sample:

#include <iostream>
#include <cstdlib>

// function to call if operator new can't allocate enough memory or error arises
void outOfMemHandler()
{
    std::cerr << "Unable to satisfy request for memory\n";

    std::abort();
}

int main()
{
    //set the new_handler
    std::set_new_handler(outOfMemHandler);

    //Request huge memory size, that will cause ::operator new to fail
    int *pBigDataArray = new int[100000000L];

    return 0;
}

In the above example, operator new (most likely) will be unable to allocate space for 100,000,000 integers, and the function outOfMemHandler() will be called, and the program will abort after issuing an error message.

As seen here the default behavior of new operator when unable to fulfill a memory request, is to call the new-handler function repeatedly until it can find enough memory or there is no more new handlers. In the above example, unless we call std::abort(), outOfMemHandler() would be called repeatedly. Therefore, the handler should either ensure that the next allocation succeeds, or register another handler, or register no handler, or not return (i.e. terminate the program). If there is no new handler and the allocation fails, the operator will throw an exception.

What is the new_handler and set_new_handler?

new_handler is a typedef for a pointer to a function that takes and returns nothing, and set_new_handler is a function that takes and returns a new_handler.

Something like:

typedef void (*new_handler)();
new_handler set_new_handler(new_handler p) throw();

set_new_handler's parameter is a pointer to the function operator new should call if it can't allocate the requested memory. Its return value is a pointer to the previously registered handler function, or null if there was no previous handler.

How to handle out of memory conditions in C++?

Given the behavior of newa well designed user program should handle out of memory conditions by providing a proper new_handlerwhich does one of the following:

Make more memory available: This may allow the next memory allocation attempt inside operator new's loop to succeed. One way to implement this is to allocate a large block of memory at program start-up, then release it for use in the program the first time the new-handler is invoked.

Install a different new-handler: If the current new-handler can't make any more memory available, and of there is another new-handler that can, then the current new-handler can install the other new-handler in its place (by calling set_new_handler). The next time operator new calls the new-handler function, it will get the one most recently installed.

(A variation on this theme is for a new-handler to modify its own behavior, so the next time it's invoked, it does something different. One way to achieve this is to have the new-handler modify static, namespace-specific, or global data that affects the new-handler's behavior.)

Uninstall the new-handler: This is done by passing a null pointer to set_new_handler. With no new-handler installed, operator new will throw an exception ((convertible to) std::bad_alloc) when memory allocation is unsuccessful.

Throw an exception convertible to std::bad_alloc. Such exceptions are not be caught by operator new, but will propagate to the site originating the request for memory.

Not return: By calling abort or exit.

The answer from dhams is correct (after having been edited several times), but as the many edits of the code shows, it is difficult to write correct and robust code for deleting a directory (with sub-dirs) yourself. So I strongly suggest using Apache Commons IO, or some other API that does this for you:

import org.apache.commons.io.FileUtils;

...

// Delete local cache dir (ignoring any errors):
FileUtils.deleteQuietly(context.getCacheDir());

PS: Also delete the directory returned by context.getExternalCacheDir() if you use that.

To be able to use Apache Commons IO, add this to your build.gradle file, in the dependencies part:

compile 'commons-io:commons-io:2.4'

How to import images into the gallery of an Android Virtual Device using Android Studio: I'm using Android Studio 1.4.1 and a API 15 virtual device.

Warning: This is manual intensive so it is not a good solution for a large number of images.

1. Create a virtual device using Android's Device Manager (AVD), Menu /Tools/Android/AVD Manager.
2. Start this virtual device.
3. Start the Android Device monitor, Menu */Tools/Android/Android Device Monitor. In the Devices tab (upper left) you should see your device. It should be Online (see this screenshot)
4. On the right window is the File Explorer. Go there and select the /mnt/sdcard/Pictures directory. It should be highlighted (see this screenshot)
5. Add jpegs to this directory by clicking on the Push a file onto the device icon (the little phone icon I highlighted in the above screenshot. You can add only one photo at a time, dadburnit.
6. Go to your device and run the Dev Tools app.
7. Scroll down and select Media Provider.
8. Click on the Scan SD Card button. This should copy the images you added in step 5 to the gallery. Go to the gallery and look, they should be there.

I had similar situation. I found that one of my config maps was duplicated. I had two configmaps for the same namespace. One had the correct namespace reference, the other was pointing to the wrong namespace.

I deleted and recreated the configmap with the correct file (or fixed file). I am only using one, and that seemed to make the particular cluster happier.

So I would check the files for any typos or duplicate items that could be causing conflict.
