It can very much be an ssh-agent issue. Check whether there is an ssh-agent PID currently running with eval "$(ssh-agent -s)"

Check whether your identity is added with ssh-add -l and if not, add it with ssh-add <pathToYourRSAKey>.

Then try again your ssh command (or any other command that spawns ssh daemons, like autossh for example) that returned 255.

Take a look at SimpleDateFormat:

java.util.Date utilDate = new java.util.Date();
java.sql.Timestamp sq = new java.sql.Timestamp(utilDate.getTime());  

SimpleDateFormat sdf = new SimpleDateFormat("dd.MM.yyyy HH:mm:ss");
System.out.println(sdf.format(sq));

instead of doing pure jquery, i would do:

$(".mytext").mouseover(function() {
    x= $(this).position().left - document.scrollLeft
    y= $(this).position().top - document.scrollTop
    $("#dialog").dialog('option', 'position', [y, x]);
}

if i am understanding your question correctly, the code you have is positioning the dialog as if the page had no scroll, but you want it to take the scroll into account. my code should do that.

Here is an example of concatenation operator:

architecture EXAMPLE of CONCATENATION is
   signal Z_BUS : bit_vector (3 downto 0);
   signal A_BIT, B_BIT, C_BIT, D_BIT : bit;
begin
   Z_BUS <= A_BIT & B_BIT & C_BIT & D_BIT;
end EXAMPLE;

Invoking of validation on form element could be handled by triggering change event on this element:

a) exemple: trigger change on separated element in form

$scope.formName.elementName.$$element.change();

b) exemple: trigger change event for each of form elements for example on ng-submit, ng-click, ng-blur ...

vm.triggerChangeForFormElements = function() {
    // trigger change event for each of form elements
    angular.forEach($scope.formName, function (element, name) {
        if (!name.startsWith('$')) {
            element.$$element.change();
        }
    });
};

c) and one more way for that

    var handdleChange = function(form){
        var formFields = angular.element(form)[0].$$controls;
        angular.forEach(formFields, function(field){
            field.$$element.change();
        });
    };

Tickcount is good, however i suggest running it 100 or 1000 times, and calculating an average. Not only makes it more measurable - in case of really fast/short functions, but helps dealing with some one-off effects caused by the overhead.

Create a file called "SetFile.bat" that contains the following line with no carriage return at the end of it...

set FileContents=

Then in your batch file do something like this...

   @echo off
   copy SetFile.bat + %1 $tmp$.bat > nul
   call $tmp$.bat
   del $tmp$.bat

%1 is the name of your input file and %FileContents% will contain the contents of the input file after the call. This will only work on a one line file though (i.e. a file containing no carriage returns). You could strip out/replace carriage returns from the file before calling the %tmp%.bat if needed.

This worked:

$("#theSelectId").prepend("<option value='' selected='selected'></option>");

Firebug Output:

  <option value="saab">Saab</option>
  <option value="mercedes">Mercedes</option>
  <option value="audi">Audi</option>

You could also use .prependTo if you wanted to reverse the order:

?$("<option>", { value: '', selected: true }).prependTo("#theSelectId");???????????

Originally, I created a database and then restored the backup file to my new empty database:

Right click on Databases > Restore Database > General : Device: [the path of back up file] ? OK

This was wrong. I shouldn't have first created the database.

Now, instead, I do this:

Right click on Databases > Restore Database > General : Device: [the path of back up file] ? OK

you can do it better with two datagridview, you add the same datasource , hide the headers of the second, set the height of the second = to the height of the rows of the first, turn off all resizable atributes of the second, synchronize the scrollbars of both, only horizontal, put the second on the botton of the first etc.

take a look:

   dgv3.ColumnHeadersVisible = false;
   dgv3.Height = dgv1.Rows[0].Height;
   dgv3.Location = new Point(Xdgvx, this.dgv1.Height - dgv3.Height - SystemInformation.HorizontalScrollBarHeight);
   dgv3.Width = dgv1.Width;

   private void dgv1_Scroll(object sender, ScrollEventArgs e)
        {
            if (e.ScrollOrientation == ScrollOrientation.HorizontalScroll)
            {
                dgv3.HorizontalScrollingOffset = e.NewValue;
            }
        }

Browser have cross domain security at client side which verify that server allowed to fetch data from your domain. If Access-Control-Allow-Origin not available in response header, browser disallow to use response in your JavaScript code and throw exception at network level. You need to configure cors at your server side.

You can fetch request using mode: 'cors'. In this situation browser will not throw execption for cross domain, but browser will not give response in your javascript function.

So in both condition you need to configure cors in your server or you need to use custom proxy server.

It means, essentially, what it says; that 'this is important, ignore subsequent rules, and any usual specificity issues, apply this rule!'

In normal use a rule defined in an external stylesheet is overruled by a style defined in the head of the document, which, in turn, is overruled by an in-line style within the element itself (assuming equal specificity of the selectors). Defining a rule with the !important 'attribute' (?) discards the normal concerns as regards the 'later' rule overriding the 'earlier' ones.

Also, ordinarily, a more specific rule will override a less-specific rule. So:

a {
    /* css */
}

Is normally overruled by:

body div #elementID ul li a {
    /* css */
}

As the latter selector is more specific (and it doesn't, normally, matter where the more-specific selector is found (in the head or the external stylesheet) it will still override the less-specific selector (in-line style attributes will always override the 'more-', or the 'less-', specific selector as it's always more specific.

If, however, you add !important to the less-specific selector's CSS declaration, it will have priority.

Using !important has its purposes (though I struggle to think of them), but it's much like using a nuclear explosion to stop the foxes killing your chickens; yes, the foxes will be killed, but so will the chickens. And the neighbourhood.

It also makes debugging your CSS a nightmare (from personal, empirical, experience).

This is more a long comment on @Sergey and @Steffen's answers. Having written similar code myself in the past I decided to check what was most performant while remembering that clarity is important too.

Result

Here is an example test run result for 10 million iterations:

2257 ms for FirstDayOfMonth_AddMethod()
2406 ms for FirstDayOfMonth_NewMethod()
6342 ms for LastDayOfMonth_AddMethod()
4037 ms for LastDayOfMonth_AddMethodWithDaysInMonth()
4160 ms for LastDayOfMonth_NewMethod()
4212 ms for LastDayOfMonth_NewMethodWithReuseOfExtMethod()
2491 ms for LastDayOfMonth_SpecialCase()

Code

I used LINQPad 4 (in C# Program mode) to run the tests with compiler optimization turned on. Here is the tested code factored as Extension methods for clarity and convenience:

public static class DateTimeDayOfMonthExtensions
{
    public static DateTime FirstDayOfMonth_AddMethod(this DateTime value)
    {
        return value.Date.AddDays(1 - value.Day);
    }
    
    public static DateTime FirstDayOfMonth_NewMethod(this DateTime value)
    {
        return new DateTime(value.Year, value.Month, 1);
    }
    
    public static DateTime LastDayOfMonth_AddMethod(this DateTime value)
    {
        return value.FirstDayOfMonth_AddMethod().AddMonths(1).AddDays(-1);
    }
    
    public static DateTime LastDayOfMonth_AddMethodWithDaysInMonth(this DateTime value)
    {
        return value.Date.AddDays(DateTime.DaysInMonth(value.Year, value.Month) - value.Day);
    }
    
    public static DateTime LastDayOfMonth_SpecialCase(this DateTime value)
    {
        return value.AddDays(DateTime.DaysInMonth(value.Year, value.Month) - 1);
    }
    
    public static int DaysInMonth(this DateTime value)
    {
        return DateTime.DaysInMonth(value.Year, value.Month);
    }
    
    public static DateTime LastDayOfMonth_NewMethod(this DateTime value)
    {
        return new DateTime(value.Year, value.Month, DateTime.DaysInMonth(value.Year, value.Month));
    }

    public static DateTime LastDayOfMonth_NewMethodWithReuseOfExtMethod(this DateTime value)
    {
        return new DateTime(value.Year, value.Month, value.DaysInMonth());
    }
}

void Main()
{
    Random rnd = new Random();
    DateTime[] sampleData = new DateTime[10000000];
    
    for(int i = 0; i < sampleData.Length; i++) {
        sampleData[i] = new DateTime(1970, 1, 1).AddDays(rnd.Next(0, 365 * 50));
    }
    
    GC.Collect();
    System.Diagnostics.Stopwatch sw = System.Diagnostics.Stopwatch.StartNew();
    for(int i = 0; i < sampleData.Length; i++) {
        DateTime test = sampleData[i].FirstDayOfMonth_AddMethod();
    }
    string.Format("{0} ms for FirstDayOfMonth_AddMethod()", sw.ElapsedMilliseconds).Dump();
    
    GC.Collect();
    sw.Restart();
    for(int i = 0; i < sampleData.Length; i++) {
        DateTime test = sampleData[i].FirstDayOfMonth_NewMethod();
    }
    string.Format("{0} ms for FirstDayOfMonth_NewMethod()", sw.ElapsedMilliseconds).Dump();
    
    GC.Collect();
    sw.Restart();
    for(int i = 0; i < sampleData.Length; i++) {
        DateTime test = sampleData[i].LastDayOfMonth_AddMethod();
    }
    string.Format("{0} ms for LastDayOfMonth_AddMethod()", sw.ElapsedMilliseconds).Dump();

    GC.Collect();
    sw.Restart();
    for(int i = 0; i < sampleData.Length; i++) {
        DateTime test = sampleData[i].LastDayOfMonth_AddMethodWithDaysInMonth();
    }
    string.Format("{0} ms for LastDayOfMonth_AddMethodWithDaysInMonth()", sw.ElapsedMilliseconds).Dump();

    GC.Collect();
    sw.Restart();
    for(int i = 0; i < sampleData.Length; i++) {
        DateTime test = sampleData[i].LastDayOfMonth_NewMethod();
    }
    string.Format("{0} ms for LastDayOfMonth_NewMethod()", sw.ElapsedMilliseconds).Dump();

    GC.Collect();
    sw.Restart();
    for(int i = 0; i < sampleData.Length; i++) {
        DateTime test = sampleData[i].LastDayOfMonth_NewMethodWithReuseOfExtMethod();
    }
    string.Format("{0} ms for LastDayOfMonth_NewMethodWithReuseOfExtMethod()", sw.ElapsedMilliseconds).Dump();

    for(int i = 0; i < sampleData.Length; i++) {
        sampleData[i] = sampleData[i].FirstDayOfMonth_AddMethod();
    }
    
    GC.Collect();
    sw.Restart();
    for(int i = 0; i < sampleData.Length; i++) {
        DateTime test = sampleData[i].LastDayOfMonth_SpecialCase();
    }
    string.Format("{0} ms for LastDayOfMonth_SpecialCase()", sw.ElapsedMilliseconds).Dump();
    
}

Analysis

I was surprised by some of these results.

Although there is not much in it the FirstDayOfMonth_AddMethod was slightly faster than FirstDayOfMonth_NewMethod in most runs of the test. However, I think the latter has a slightly clearer intent and so I have a preference for that.

LastDayOfMonth_AddMethod was a clear loser against LastDayOfMonth_AddMethodWithDaysInMonth, LastDayOfMonth_NewMethod and LastDayOfMonth_NewMethodWithReuseOfExtMethod. Between the fastest three there is nothing much in it and so it comes down to your personal preference. I choose the clarity of LastDayOfMonth_NewMethodWithReuseOfExtMethod with its reuse of another useful extension method. IMHO its intent is clearer and I am willing to accept the small performance cost.

LastDayOfMonth_SpecialCase assumes you are providing the first of the month in the special case where you may have already calculated that date and it uses the add method with DateTime.DaysInMonth to get the result. This is faster than the other versions, as you would expect, but unless you are in a desperate need for speed I don't see the point of having this special case in your arsenal.

Conclusion

Here is an extension method class with my choices and in general agreement with @Steffen I believe:

public static class DateTimeDayOfMonthExtensions
{
    public static DateTime FirstDayOfMonth(this DateTime value)
    {
        return new DateTime(value.Year, value.Month, 1);
    }
    
    public static int DaysInMonth(this DateTime value)
    {
        return DateTime.DaysInMonth(value.Year, value.Month);
    }
    
    public static DateTime LastDayOfMonth(this DateTime value)
    {
        return new DateTime(value.Year, value.Month, value.DaysInMonth());
    }
}

If you have got this far, thank you for time! Its been fun :¬). Please comment if you have any other suggestions for these algorithms.

From the man git-stash page:

The modifications stashed away by this command can be listed with git stash list, inspected with git stash show

show [<stash>]
       Show the changes recorded in the stash as a diff between the stashed state and
       its original parent. When no <stash> is given, shows the latest one. By default,
       the command shows the diffstat, but it will accept any format known to git diff
       (e.g., git stash show -p stash@{1} to view the second most recent stash in patch
       form).

To list the stashed modifications

git stash list

To show files changed in the last stash

git stash show

So, to view the content of the most recent stash, run

git stash show -p

To view the content of an arbitrary stash, run something like

git stash show -p stash@{1}

I know you said you don't care about how secure it is, but if you chose DES you might as well take AES it is the more up-to-date encryption method.

Try:

RENAME database1 TO database2;

There are two ways to access properties of an object:

• Dot notation: something.bar
• Bracket notation: something['bar']

The value between the brackets can be any expression. Therefore, if the property name is stored in a variable, you have to use bracket notation:

var something = {
  bar: 'foo'
};
var foo = 'bar';

// both x = something[foo] and something[foo] = x work as expected
console.log(something[foo]);
console.log(something.bar)

You cannot use the syntax you have suggested. If you have a C99 compiler, though, you can do this:

int *p;

p = malloc(3 * sizeof p[0]);
memcpy(p, (int []){ 0, 1, 2 }, 3 * sizeof p[0]);

If your compiler does not support C99 compound literals, you need to use a named template to copy from:

int *p;

p = malloc(3 * sizeof p[0]);
{
    static const int p_init[] = { 0, 1, 2 };
    memcpy(p, p_init, 3 * sizeof p[0]);
}

Auth::routes() is just a helper class that helps you generate all the routes required for user authentication. You can browse the code here https://github.com/laravel/framework/blob/5.3/src/Illuminate/Routing/Router.php instead.

Here are the routes

// Authentication Routes...
$this->get('login', 'Auth\LoginController@showLoginForm')->name('login');
$this->post('login', 'Auth\LoginController@login');
$this->post('logout', 'Auth\LoginController@logout')->name('logout');

// Registration Routes...
$this->get('register', 'Auth\RegisterController@showRegistrationForm')->name('register');
$this->post('register', 'Auth\RegisterController@register');

// Password Reset Routes...
$this->get('password/reset', 'Auth\ForgotPasswordController@showLinkRequestForm');
$this->post('password/email', 'Auth\ForgotPasswordController@sendResetLinkEmail');
$this->get('password/reset/{token}', 'Auth\ResetPasswordController@showResetForm');
$this->post('password/reset', 'Auth\ResetPasswordController@reset');

This works in webpack 3:

in the webpack.config.babel.js file:

resolve: {
    alias: {
         jquery: "jquery/src/jquery"
    },
 ....
}

And use ProvidePlugin

new webpack.ProvidePlugin({
        '$': 'jquery',
        'jQuery': 'jquery',
    })

There's also a really useful discussion about converting the array in place, In-place type conversion of a NumPy array. If you're concerned about copying your array (which is whatastype() does) definitely check out the link.

function myfunction() {
     if(a == 'stop') 
         return false;
}

return false; is much better than just return;

SELECT * FROM Customers ORDER BY ID DESC LIMIT 1

Then get the ID.

The answer is in the documentation:

Real partial mocks (Since 1.8.0)

Finally, after many internal debates & discussions on the mailing list, partial mock support was added to Mockito. Previously we considered partial mocks as code smells. However, we found a legitimate use case for partial mocks.

Before release 1.8 spy() was not producing real partial mocks and it was confusing for some users. Read more about spying: here or in javadoc for spy(Object) method.

callRealMethod() was introduced after spy(), but spy() was left there of course, to ensure backward compatibility.

Otherwise, you're right: all the methods of a spy are real unless stubbed. All the methods of a mock are stubbed unless callRealMethod() is called. In general, I would prefer using callRealMethod(), because it doesn't force me to use the doXxx().when() idiom instead of the traditional when().thenXxx()

I recommend you to use the open-source package guzzle that is fully unit tested and uses the latest coding practices.

Installing Guzzle

Go to the command line in your project folder and type in the following command (assuming you already have the package manager composer installed). If you need help how to install Composer, you should have a look here.

php composer.phar require guzzlehttp/guzzle

Using Guzzle to send a POST request

The usage of Guzzle is very straight forward as it uses a light-weight object-oriented API:

// Initialize Guzzle client
$client = new GuzzleHttp\Client();

// Create a POST request
$response = $client->request(
    'POST',
    'http://example.org/',
    [
        'form_params' => [
            'key1' => 'value1',
            'key2' => 'value2'
        ]
    ]
);

// Parse the response object, e.g. read the headers, body, etc.
$headers = $response->getHeaders();
$body = $response->getBody();

// Output headers and body for debugging purposes
var_dump($headers, $body);

You have two options:

1. Configure Workspace Settings (disable the validation for the current workspace): Go to Window > Preferences > Validation and uncheck the manual and build for: XML Schema Validator, XML Validator

2. Check enable project specific settings (disable the validation for this project): Right-click on the project, select Properties > Validation and uncheck the manual and build for: XML Schema Validator, XML Validator

Right-click on the project and select Validate to make the errors disappear.

Actually, your code will pretty much work as is, just declare your callback as an argument and you can call it directly using the argument name.

The basics

function doSomething(callback) {
    // ...

    // Call the callback
    callback('stuff', 'goes', 'here');
}

function foo(a, b, c) {
    // I'm the callback
    alert(a + " " + b + " " + c);
}

doSomething(foo);

That will call doSomething, which will call foo, which will alert "stuff goes here".

Note that it's very important to pass the function reference (foo), rather than calling the function and passing its result (foo()). In your question, you do it properly, but it's just worth pointing out because it's a common error.

More advanced stuff

Sometimes you want to call the callback so it sees a specific value for this. You can easily do that with the JavaScript call function:

function Thing(name) {
    this.name = name;
}
Thing.prototype.doSomething = function(callback) {
    // Call our callback, but using our own instance as the context
    callback.call(this);
}

function foo() {
    alert(this.name);
}

var t = new Thing('Joe');
t.doSomething(foo);  // Alerts "Joe" via `foo`

You can also pass arguments:

function Thing(name) {
    this.name = name;
}
Thing.prototype.doSomething = function(callback, salutation) {
    // Call our callback, but using our own instance as the context
    callback.call(this, salutation);
}

function foo(salutation) {
    alert(salutation + " " + this.name);
}

var t = new Thing('Joe');
t.doSomething(foo, 'Hi');  // Alerts "Hi Joe" via `foo`

Sometimes it's useful to pass the arguments you want to give the callback as an array, rather than individually. You can use apply to do that:

function Thing(name) {
    this.name = name;
}
Thing.prototype.doSomething = function(callback) {
    // Call our callback, but using our own instance as the context
    callback.apply(this, ['Hi', 3, 2, 1]);
}

function foo(salutation, three, two, one) {
    alert(salutation + " " + this.name + " - " + three + " " + two + " " + one);
}

var t = new Thing('Joe');
t.doSomething(foo);  // Alerts "Hi Joe - 3 2 1" via `foo`

You can use

Trace.WriteLine("text");

This will output to the "Output" window in Visual Studio (when debugging).

make sure to have the Diagnostics assembly included:

using System.Diagnostics;

I have a similar situation but I want a consistent way to be able to use DateTime.Parse from the filename as well, so I went with

DateTime.Now.ToString("s").Replace(":", ".") // <-- 2016-10-25T16.50.35

When I want to parse, I can simply reverse the Replace call. This way I don't have to type in any yymmdd stuff or guess what formats DateTime.Parse allows.

I'd also suggest moving the event handler outside render.

var OnSubmitTest = React.createClass({

  submit: function(e){
    e.preventDefault();
    alert('it works!');
  }

  render: function() {
    return (
      <form onSubmit={this.submit}>
        <button>Click me</button>
      </form>
    );
  }
});

There are multiple ways of applying aggregate functions to multiple columns.

GroupedData class provides a number of methods for the most common functions, including count, max, min, mean and sum, which can be used directly as follows:

• Python:

  df = sqlContext.createDataFrame(
      [(1.0, 0.3, 1.0), (1.0, 0.5, 0.0), (-1.0, 0.6, 0.5), (-1.0, 5.6, 0.2)],
      ("col1", "col2", "col3"))
  
  df.groupBy("col1").sum()
  
  ## +----+---------+-----------------+---------+
  ## |col1|sum(col1)|        sum(col2)|sum(col3)|
  ## +----+---------+-----------------+---------+
  ## | 1.0|      2.0|              0.8|      1.0|
  ## |-1.0|     -2.0|6.199999999999999|      0.7|
  ## +----+---------+-----------------+---------+
  

• Scala

  val df = sc.parallelize(Seq(
    (1.0, 0.3, 1.0), (1.0, 0.5, 0.0),
    (-1.0, 0.6, 0.5), (-1.0, 5.6, 0.2))
  ).toDF("col1", "col2", "col3")
  
  df.groupBy($"col1").min().show
  
  // +----+---------+---------+---------+
  // |col1|min(col1)|min(col2)|min(col3)|
  // +----+---------+---------+---------+
  // | 1.0|      1.0|      0.3|      0.0|
  // |-1.0|     -1.0|      0.6|      0.2|
  // +----+---------+---------+---------+
  

Optionally you can pass a list of columns which should be aggregated

df.groupBy("col1").sum("col2", "col3")

You can also pass dictionary / map with columns a the keys and functions as the values:

• Python

  exprs = {x: "sum" for x in df.columns}
  df.groupBy("col1").agg(exprs).show()
  
  ## +----+---------+
  ## |col1|avg(col3)|
  ## +----+---------+
  ## | 1.0|      0.5|
  ## |-1.0|     0.35|
  ## +----+---------+
  

• Scala

  val exprs = df.columns.map((_ -> "mean")).toMap
  df.groupBy($"col1").agg(exprs).show()
  
  // +----+---------+------------------+---------+
  // |col1|avg(col1)|         avg(col2)|avg(col3)|
  // +----+---------+------------------+---------+
  // | 1.0|      1.0|               0.4|      0.5|
  // |-1.0|     -1.0|3.0999999999999996|     0.35|
  // +----+---------+------------------+---------+
  

Finally you can use varargs:

• Python

  from pyspark.sql.functions import min
  
  exprs = [min(x) for x in df.columns]
  df.groupBy("col1").agg(*exprs).show()
  

• Scala

  import org.apache.spark.sql.functions.sum
  
  val exprs = df.columns.map(sum(_))
  df.groupBy($"col1").agg(exprs.head, exprs.tail: _*)
  

There are some other way to achieve a similar effect but these should more than enough most of the time.

The order of execution of ng-click and ng-model is different with angular 1.2 vs 1.6

You must test, with 1.2 and 1.6,

for example, with angular 1.2, ng-click get execute before ng-model, with angular 1.6, ng-model maybe get excute before ng-click.

so you get 'true checked' / 'false uncheck' value maybe not you expect

function GetPixel(context, x, y)
{
    var p = context.getImageData(x, y, 1, 1).data; 
    var hex = "#" + ("000000" + rgbToHex(p[0], p[1], p[2])).slice(-6);  
    return hex;
}

function rgbToHex(r, g, b) {
    if (r > 255 || g > 255 || b > 255)
        throw "Invalid color component";
    return ((r << 16) | (g << 8) | b).toString(16);
}

You need to correctly separate static data from instance data. In your code, onLoan and setLoanItem() are instance members. If you want to reference/call them you must do so via an instance. So you either want

public void loanItem() {
    this.media.setLoanItem("Yes");
}

or

public void loanItem(Media object) {
    object.setLoanItem("Yes");
}

depending on how you want to pass that instance around.

You can use segments to add the bars in base graphics. Here epsilon controls the line across the top and bottom of the line.

plot (x, y, ylim=c(0, 6))
epsilon = 0.02
for(i in 1:5) {
    up = y[i] + sd[i]
    low = y[i] - sd[i]
    segments(x[i],low , x[i], up)
    segments(x[i]-epsilon, up , x[i]+epsilon, up)
    segments(x[i]-epsilon, low , x[i]+epsilon, low)
}

As @thelatemail points out, I should really have used vectorised function calls:

segments(x, y-sd,x, y+sd)
epsilon = 0.02
segments(x-epsilon,y-sd,x+epsilon,y-sd)
segments(x-epsilon,y+sd,x+epsilon,y+sd)

JLabel is actually capable of displaying some rudimentary HTML, which is why it is not responding to your use of the newline character (unlike, say, System.out).

If you put in the corresponding HTML and used <BR>, you would get your newlines.

To resolve this problem set value for apc.shm_size as integer Locate your apc.ini file (In my system apc.ini file location /etc/php5/conf.d/apc.ini) and set: apc.shm_size = 1000

My solution to the problem is to wrap the function and thread in a class. Does not require using pools,queues, or c type variable passing. It is also non blocking. You check status instead. See example of how to use it at end of code.

import threading

class ThreadWorker():
    '''
    The basic idea is given a function create an object.
    The object can then run the function in a thread.
    It provides a wrapper to start it,check its status,and get data out the function.
    '''
    def __init__(self,func):
        self.thread = None
        self.data = None
        self.func = self.save_data(func)

    def save_data(self,func):
        '''modify function to save its returned data'''
        def new_func(*args, **kwargs):
            self.data=func(*args, **kwargs)

        return new_func

    def start(self,params):
        self.data = None
        if self.thread is not None:
            if self.thread.isAlive():
                return 'running' #could raise exception here

        #unless thread exists and is alive start or restart it
        self.thread = threading.Thread(target=self.func,args=params)
        self.thread.start()
        return 'started'

    def status(self):
        if self.thread is None:
            return 'not_started'
        else:
            if self.thread.isAlive():
                return 'running'
            else:
                return 'finished'

    def get_results(self):
        if self.thread is None:
            return 'not_started' #could return exception
        else:
            if self.thread.isAlive():
                return 'running'
            else:
                return self.data

def add(x,y):
    return x +y

add_worker = ThreadWorker(add)
print add_worker.start((1,2,))
print add_worker.status()
print add_worker.get_results()

In C++ and C switches only work on integer types. Use an if else ladder instead. C++ could obviously have implemented some sort of swich statement for strings - I guess nobody thought it worthwhile, and I agree with them.

Lambda expressions are typically used to encapsulate algorithms so that they can be passed to another function. However, it is possible to execute a lambda immediately upon definition:

[&](){ ...your code... }(); // immediately executed lambda expression

is functionally equivalent to

{ ...your code... } // simple code block

This makes lambda expressions a powerful tool for refactoring complex functions. You start by wrapping a code section in a lambda function as shown above. The process of explicit parameterization can then be performed gradually with intermediate testing after each step. Once you have the code-block fully parameterized (as demonstrated by the removal of the &), you can move the code to an external location and make it a normal function.

Similarly, you can use lambda expressions to initialize variables based on the result of an algorithm...

int a = []( int b ){ int r=1; while (b>0) r*=b--; return r; }(5); // 5!

As a way of partitioning your program logic, you might even find it useful to pass a lambda expression as an argument to another lambda expression...

[&]( std::function<void()> algorithm ) // wrapper section
   {
   ...your wrapper code...
   algorithm();
   ...your wrapper code...
   }
([&]() // algorithm section
   {
   ...your algorithm code...
   });

Lambda expressions also let you create named nested functions, which can be a convenient way of avoiding duplicate logic. Using named lambdas also tends to be a little easier on the eyes (compared to anonymous inline lambdas) when passing a non-trivial function as a parameter to another function. Note: don't forget the semicolon after the closing curly brace.

auto algorithm = [&]( double x, double m, double b ) -> double
   {
   return m*x+b;
   };

int a=algorithm(1,2,3), b=algorithm(4,5,6);

If subsequent profiling reveals significant initialization overhead for the function object, you might choose to rewrite this as a normal function.

Here is the alternative command:

gnuplot -p -e 'plot for [file in system("find . -name \\*.txt -depth 1")] file using 1:2 title file with lines'

I've developed a dotnet library that might come in useful. I have fixed the problem of never getting all of the data if it exceeds the buffer, which many posts have discounted. Still some problems with the solution but works descently well https://github.com/NicholasLKSharp/DotNet-TCP-Communication

There`s my solution. It will compare arrays which also have objects and arrays. Elements can be stay in any positions. Example:

const array1 = [{a: 1}, {b: 2}, { c: 0, d: { e: 1, f: 2, } }, [1,2,3,54]];
const array2 = [{a: 1}, {b: 2}, { c: 0, d: { e: 1, f: 2, } }, [1,2,3,54]];

const arraysCompare = (a1, a2) => {
  if (a1.length !== a2.length) return false;
  const objectIteration = (object) => {
    const result = [];
    const objectReduce = (obj) => {
      for (let i in obj) {
        if (typeof obj[i] !== 'object') {
          result.push(`${i}${obj[i]}`);
        } else {
          objectReduce(obj[i]);
        }
      }
    };
    objectReduce(object);
    return result;
  };
  const reduceArray1 = a1.map(item => {
    if (typeof item !== 'object') return item;
    return objectIteration(item).join('');
  });
  const reduceArray2 = a2.map(item => {
    if (typeof item !== 'object') return item;
    return objectIteration(item).join('');
  });
  const compare =  reduceArray1.map(item => reduceArray2.includes(item));
  return compare.reduce((acc, item) => acc + Number(item)) === a1.length;
};

console.log(arraysCompare(array1, array2));

One more way:

scala> val xs = Array("first", "second", "third")
xs: Array[java.lang.String] = Array(first, second, third)

scala> for (i <- xs.indices)
     |   println(i + ": " + xs(i))
0: first
1: second
2: third

Just a quick chime in here to hopefully help others... Especially with the newer version (since this is 2 years old)...

Instead of having some static fields defined in JS, you can also use the data-rule-* attributes. You can use built-in rules as well as custom rules.

See http://jqueryvalidation.org/documentation/#link-list-of-built-in-validation-methods for built-in rules.

Example:

<p><label>Email: <input type="text" name="email" id="email" data-rule-email="true" required></label></p>
<p><label>Confirm Email: <input type="text" name="email" id="email_confirm" data-rule-email="true" data-rule-equalTo="#email" required></label></p>

Note the data-rule-* attributes.

I use a css class like so to target the modal-dialog class:

.app-modal-window .modal-dialog {
  width: 500px;
}

Then in the controller calling the modal window, set the windowClass:

    $scope.modalButtonClick = function () {
        var modalInstance = $modal.open({
            templateUrl: 'App/Views/modalView.html',
            controller: 'modalController',
            windowClass: 'app-modal-window'
        });
        modalInstance.result.then(
            //close
            function (result) {
                var a = result;
            },
            //dismiss
            function (result) {
                var a = result;
            });
    };

The script below is a generic solution that works for me. It is based on ideas pulled from this and other threads.

When a link with an href attribute beginning with "#" is clicked, it scrolls the page smoothly to the indicated div. Where only the "#" is present, it scrolls smoothly to the top of the page.

$('a[href^=#]').click(function(){
    event.preventDefault();
    var target = $(this).attr('href');
    if (target == '#')
      $('html, body').animate({scrollTop : 0}, 600);
    else
      $('html, body').animate({
        scrollTop: $(target).offset().top - 100
    }, 600);
});

For example, When the code above is present, clicking a link with the tag <a href="#"> scrolls to the top of the page at speed 600. Clicking a link with the tag <a href="#mydiv"> scrolls to 100px above <div id="mydiv"> at speed 600. Feel free to change these numbers.

I hope it helps!

You can find a whole bunch of Linq examples in visual studio. Just select Help -> Samples, and then unzip the Linq samples.

Open the linq samples solution and open the LinqSamples.cs of the SampleQueries project.

The answer you are looking for is in method Linq14:

int[] numbersA = { 0, 2, 4, 5, 6, 8, 9 };
int[] numbersB = { 1, 3, 5, 7, 8 };

var pairs =
   from a in numbersA
   from b in numbersB
   where a < b
   select new {a, b};

Using IReadOnlyCollection<T> or IReadOnlyList<T> in the method signature instead of IEnumerable<T>, has the advantage of making explicit that you might need to check the count before iterating, or to iterate multiple times for some other reason.

However they have a huge downside that will cause problems if you try to refactor your code to use interfaces, for instance to make it more testable and friendly to dynamic proxying. The key point is that IList<T> does not inherit from IReadOnlyList<T>, and similarly for other collections and their respective read-only interfaces. (In short, this is because .NET 4.5 wanted to keep ABI compatibility with earlier versions. But they didn't even take the opportunity to change that in .NET core.)

This means that if you get an IList<T> from some part of the program and want to pass it to another part that expects an IReadOnlyList<T>, you can't! You can however pass an IList<T> as an IEnumerable<T>.

In the end, IEnumerable<T> is the only read-only interface supported by all .NET collections including all collection interfaces. Any other alternative will come back to bite you as you realize that you locked yourself out from some architecture choices. So I think it's the proper type to use in function signatures to express that you just want a read-only collection.

(Note that you can always write a IReadOnlyList<T> ToReadOnly<T>(this IList<T> list) extension method that simple casts if the underlying type supports both interfaces, but you have to add it manually everywhere when refactoring, where as IEnumerable<T> is always compatible.)

As always this is not an absolute, if you're writing database-heavy code where accidental multiple enumeration would be a disaster, you might prefer a different trade-off.

I know this question already have been answer but I have made some update to the GD function :

  ### COST FUNCTION

def cost(theta,X,y):
     ### Evaluate half MSE (Mean square error)
     m = len(y)
     error = np.dot(X,theta) - y
     J = np.sum(error ** 2)/(2*m)
     return J

 cost(theta,X,y)



def GD(X,y,theta,alpha):

    cost_histo = [0]
    theta_histo = [0]

    # an arbitrary gradient, to pass the initial while() check
    delta = [np.repeat(1,len(X))]
    # Initial theta
    old_cost = cost(theta,X,y)

    while (np.max(np.abs(delta)) > 1e-6):
        error = np.dot(X,theta) - y
        delta = np.dot(np.transpose(X),error)/len(y)
        trial_theta = theta - alpha * delta
        trial_cost = cost(trial_theta,X,y)
        while (trial_cost >= old_cost):
            trial_theta = (theta +trial_theta)/2
            trial_cost = cost(trial_theta,X,y)
            cost_histo = cost_histo + trial_cost
            theta_histo = theta_histo +  trial_theta
        old_cost = trial_cost
        theta = trial_theta
    Intercept = theta[0] 
    Slope = theta[1]  
    return [Intercept,Slope]

res = GD(X,y,theta,alpha)

This function reduce the alpha over the iteration making the function too converge faster see Estimating linear regression with Gradient Descent (Steepest Descent) for an example in R. I apply the same logic but in Python.

Git will automatically detect the move/rename if your modification is not too severe. Just git add the new file, and git rm the old file. git status will then show whether it has detected the rename.

additionally, for moves around directories, you may need to:

1. cd to the top of that directory structure.
2. Run git add -A .
3. Run git status to verify that the "new file" is now a "renamed" file

If git status still shows "new file" and not "renamed" you need to follow Hank Gay’s advice and do the move and modify in two separate commits.

If you want to create dynamically/runtime data table in VB.Net then you should follow these steps as mentioned below :

• Create Data table object.
• Add columns into that data table object.
• Add Rows with values into the object.

For eg.

Dim dt As New DataTable

dt.Columns.Add("Id", GetType(Integer))
dt.Columns.Add("FirstName", GetType(String))
dt.Columns.Add("LastName", GetType(String))

dt.Rows.Add(1, "Test", "data")
dt.Rows.Add(15, "Robert", "Wich")
dt.Rows.Add(18, "Merry", "Cylon")
dt.Rows.Add(30, "Tim", "Burst")

To define this on a permanent basis for the current user, create (or edit) the .vimrc file:

$ vim ~/.vimrc

Then, paste the configuration below into the file. Once vim is restarted, the tab settings will apply.

set tabstop=4       " The width of a TAB is set to 4.
                    " Still it is a \t. It is just that
                    " Vim will interpret it to be having
                    " a width of 4.

set shiftwidth=4    " Indents will have a width of 4

set softtabstop=4   " Sets the number of columns for a TAB

set expandtab       " Expand TABs to spaces

Expanding Rentering.com's answer, in scenarios where a whole graph of many types is to be taken care of, and you're looking for a strongly typed solution, this class can help, see usage (fluent) below.

The short answer is: most of the time time.clock() will be better. However, if you're timing some hardware (for example some algorithm you put in the GPU), then time.clock() will get rid of this time and time.time() is the only solution left.

Note: whatever the method used, the timing will depend on factors you cannot control (when will the process switch, how often, ...), this is worse with time.time() but exists also with time.clock(), so you should never run one timing test only, but always run a series of test and look at mean/variance of the times.

That's the usual problem, you cannot see a missing unmanaged DLL with Fuslogvw.exe. Best thing to do is to run SysInternals' ProcMon utility. You'll see it searching for the DLL and not find it. Profile mode in Dependency Walker can show it too.

break used to get out from the loop statement, but continue just stop script on specific condition and then continue looping statement until reach the end..

for($i=0; $i<10; $i++){
    if($i == 5){
        echo "It reach five<br>";
        continue;
    }
    echo $i . "<br>";
}

echo "<hr>";

for($i=0; $i<10; $i++){
    if($i == 5){
         echo "It reach end<br>";
         break;

It's not smart enough to realize it's still a "vector" in math terms.

Say rather that it's smart enough to recognize a difference in dimensionality. :-)

I think the simplest thing you can do is select that row positionally using iloc, which gives you a Series with the columns as the new index and the values as the values:

>>> df = pd.DataFrame([list(range(5))], columns=["a{}".format(i) for i in range(5)])
>>> df
   a0  a1  a2  a3  a4
0   0   1   2   3   4
>>> df.iloc[0]
a0    0
a1    1
a2    2
a3    3
a4    4
Name: 0, dtype: int64
>>> type(_)
<class 'pandas.core.series.Series'>

list.append returns None, since it is an in-place operation and you are assigning it back to dates_dict[key]. So, the next time when you do dates_dict.get(key, []).append you are actually doing None.append. That is why it is failing. Instead, you can simply do

dates_dict.setdefault(key, []).append(date)

But, we have collections.defaultdict for this purpose only. You can do something like this

from collections import defaultdict
dates_dict = defaultdict(list)
for key, date in cur:
    dates_dict[key].append(date)

This will create a new list object, if the key is not found in the dictionary.

Note: Since the defaultdict will create a new list if the key is not found in the dictionary, this will have unintented side-effects. For example, if you simply want to retrieve a value for the key, which is not there, it will create a new list and return it.

To overrule the default strategy you can create a simple method in the class where you are wired your restTemplate:

 protected void acceptEveryCertificate() throws KeyStoreException, NoSuchAlgorithmException, KeyManagementException {

    TrustStrategy acceptingTrustStrategy = new TrustStrategy() {
        @Override
        public boolean isTrusted(X509Certificate[] x509Certificates, String s) throws CertificateException {
            return true;
        }
    };

    restTemplate.setRequestFactory(new HttpComponentsClientHttpRequestFactory(
            HttpClientBuilder
                    .create()
                    .setSSLContext(SSLContexts.custom().loadTrustMaterial(null, acceptingTrustStrategy).build())
                    .build()));
}

Note: Surely you need to handle exceptions since this method only throws them further!

I have experienced exactly the same problem. In my case, the source of it was the permissions of the folder in which I wanted to create the zip file that were all set to read only. I changed it to read and write and it worked.

If the file is not created on your local-server when you run the script, you most probably have the same problem as I did.

Basically we had to enable TLS 1.2 for .NET 4.x. Making this registry changed worked for me, and stopped the event log filling up with the Schannel error.

More information on the answer can be found here

Linked Info Summary

Enable TLS 1.2 at the system (SCHANNEL) level:

Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.2]
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.2\Client]
"DisabledByDefault"=dword:00000000
"Enabled"=dword:00000001
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.2\Server]
"DisabledByDefault"=dword:00000000
"Enabled"=dword:00000001

(equivalent keys are probably also available for other TLS versions)

Tell .NET Framework to use the system TLS versions:

Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework\v4.0.30319]
"SystemDefaultTlsVersions"=dword:00000001
[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\.NETFramework\v4.0.30319]
"SystemDefaultTlsVersions"=dword:00000001

This may not be desirable for edge cases where .NET Framework 4.x applications need to have different protocols enabled and disabled than the OS does.

There is an excellent summary of this feature in the article The For-Each Loop. It shows by example how using the for-each style can produce clearer code that is easier to read and write.

remove the http or https from wget https:github.com/facebook/facebook-php-sdk/archive/master.zip . this worked fine for me.

It's rather difficult to give a practical answer because the difference is about the language definition itself. It's possible to build an interpreter for every compiled language, but it's not possible to build an compiler for every interpreted language. It's very much about the formal definition of a language.

One interesting difference :

lst=[1]
print lst          // prints [1]
print type(lst)    // prints <type 'list'>

notATuple=(1)
print notATuple        // prints 1
print type(notATuple)  // prints <type 'int'>
                                         ^^ instead of tuple(expected)

A comma must be included in a tuple even if it contains only a single value. e.g. (1,) instead of (1).

While working with spark in EMR I was having the same problem and setting maximizeResourceAllocation=true did the trick; hope it helps someone. You have to set it when you create the cluster. From the EMR docs:

aws emr create-cluster --release-label emr-5.4.0 --applications Name=Spark \
--instance-type m3.xlarge --instance-count 2 --service-role EMR_DefaultRole --ec2-attributes InstanceProfile=EMR_EC2_DefaultRole --configurations https://s3.amazonaws.com/mybucket/myfolder/myConfig.json

Where myConfig.json should say:

[
  {
    "Classification": "spark",
    "Properties": {
      "maximizeResourceAllocation": "true"
    }
  }
]

Easiest way to Get SHA-1 For Release and Debug mode android studio gradle. Check this

How about this?

fscanf(file,"%d %d %d %d %d %d %d",&line1_1,&line1_2, &line1_3, &line2_1, &line2_2, &line3_1, &line3_2); 

In this case spaces in fscanf match multiple occurrences of any whitespace until the next token in found.

This is a modified function from a similar question, modified as per the suggestion of https://stackoverflow.com/a/18267932/700597.

This function will convert a hexadecimal string - NOT prepended with "0x" - with an even number of characters to the number of bytes specified. It will return -1 if it encounters an invalid character, or if the hex string has an odd length, and 0 on success.

//convert hexstring to len bytes of data
//returns 0 on success, -1 on error
//data is a buffer of at least len bytes
//hexstring is upper or lower case hexadecimal, NOT prepended with "0x"
int hex2data(unsigned char *data, const unsigned char *hexstring, unsigned int len)
{
    unsigned const char *pos = hexstring;
    char *endptr;
    size_t count = 0;

    if ((hexstring[0] == '\0') || (strlen(hexstring) % 2)) {
        //hexstring contains no data
        //or hexstring has an odd length
        return -1;
    }

    for(count = 0; count < len; count++) {
        char buf[5] = {'0', 'x', pos[0], pos[1], 0};
        data[count] = strtol(buf, &endptr, 0);
        pos += 2 * sizeof(char);

        if (endptr[0] != '\0') {
            //non-hexadecimal character encountered
            return -1;
        }
    }

    return 0;
}

If tomorrow you decide you don't love Marry either she can be replaced as well:

Although this question is old, it is still asked by many who use MSYS2.

I started to use it this year to replace CygWin, and I'm getting pretty satisfied.

To install make, open the MSYS2 shell and type the following commands:

# Update the package database and core system packages
pacman -Syu
# Close shell and open again if needed

# Update again
pacman -Su

# Install make
pacman -S make

# Test it (show version)
make -v

Really depends on your requirement, although lately I have seen a trend for classes with at least one bare constructor defined.

The upside of posting your parameters in via constructor is that you know those values can be relied on after instantiation. The downside is that you'll need to put more work in with any library that expects to be able to create objects with a bare constructor.

My personal preference is to go with a bare constructor and set any properties as part of the declaration.

Person p=new Person()
{
   Name = "Han Solo",
   Age = 39
};

This gets around the "class lacks bare constructor" problem, plus reduces maintenance ( I can set more things without changing the constructor ).

You can also map the share to a local drive as follows:

net use X: "\\servername\share" /user:morgan password

I had similar problems and to my surprise what I found that one of my developer had saved web.config in the same folder/solution as web123.config and by mistake both of these files were uploaded.

As soon as I deleted the web123.config file, this error disappeared and ajax framework was loading correctly. even though I have

<compilation debug="true">

In my case I also have following segment. My project is using framework 3.5

I know this is a little late, but if someone else comes across this looking, you can now use public_path(); in Laravel 4, it has been added to the helper.php file in the support folder see here.

DON'T DO THIS. Raising a bare Exception is absolutely not the right thing to do; see Aaron Hall's excellent answer instead.

Can't get much more pythonic than this:

raise Exception("I know python!")

See the raise statement docs for python if you'd like more info.

Here's an updated version of the procedure which is safer.

git reset --hard HEAD^ 
git push --force-with-lease

git push -f will indiscriminately replace the remote repository with your own changes. If someone else has pushed changes they will be lost. git push --force-with-lease will only push your rebase if the repository is as you expect. If someone else has already pushed your push will fail.

See –force considered harmful; understanding git’s –force-with-lease.

I recommend aliasing this as repush = push --force-with-lease.

What if somebody has already pulled the repo? What would I do then?

Tell them to git pull --rebase=merges. Instead of a git fetch origin and git merge origin/master it will git fetch origin and git rebase -r origin/master. This will rewrite any of their local changes to master on top of the new rebased origin/master. -r will preserve any merges they may have made.

I recommend making this the default behavior for pulling. It is safe, will handle other's rebasing, and results in less unnecessary merges.

[pull]
        rebase = merges

I wanted to add to this a little bit as I am a new Android developer as well. The accepted answer is great, but I did run into some trouble. I wasn't sure how to add in the color to the colors.xml file. Here is how it should be done:

colors.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>
     <color name="class_zero_background">#7f040000</color>
     <color name="transparent">#00000000</color>
</resources>

In my original colors.xml file I had the tag "drawable":

<drawable name="class_zero_background">#7f040000</drawable>

And so I did that for the color as well, but I didn't understand that the "@color/" reference meant look for the tag "color" in the XML. I thought that I should mention this as well to help anyone else out.

I think this answers the question best, it actually changes the alpha value of something that has been drawn already. Maybe this wasn't part of the api when this question was asked.

Given 2d context c.

function reduceAlpha(x, y, w, h, dA) {
    let screenData = c.getImageData(x, y, w, h);
    for(let i = 3; i < screenData.data.length; i+=4){
        screenData.data[i] -= dA; //delta-Alpha
    }
    c.putImageData(screenData, x, y );
}

Use the .str()-method:

Manages the contents of the underlying string object.

1) Returns a copy of the underlying string as if by calling rdbuf()->str().

2) Replaces the contents of the underlying string as if by calling rdbuf()->str(new_str)...

Notes

The copy of the underlying string returned by str is a temporary object that will be destructed at the end of the expression, so directly calling c_str() on the result of str() (for example in auto *ptr = out.str().c_str();) results in a dangling pointer...

Encountered similar error. resetting chrome://net-internals/#hsts did not work for me. The issue was that my vm's clock was skewed by days. resetting the time did work out to resolve this issue. https://support.google.com/chrome/answer/4454607?hl=en

There are a few ways to go about this. One option would be to use inputfile.read() instead of inputfile.readlines() - you'd need to write separate code to strip the first four lines, but if you want the final output as a single string anyway, this might make the most sense.

A second, simpler option would be to rejoin the strings after striping the first four lines with my_text = ''.join(my_text). This is a little inefficient, but if speed isn't a major concern, the code will be simplest.

Finally, if you actually want the output as a list of strings instead of a single string, you can just modify your data parser to iterate over the list. That might looks something like this:

def data_parser(lines, dic):
    for i, j in dic.iteritems():
        for (k, line) in enumerate(lines):
            lines[k] = line.replace(i, j)
    return lines

Try this: use Find to iterate through all lines with "Current date/time", and write each line to the same file:

for /f "usebackq delims==" %i in (`find "Current date" log.txt`) do (echo %i > log-time.txt)
type log-time.txt

Set delims= to a character not relevant in the date/time lines. Use %%i in batch files.

Explanation (update):

Find extracts all lines from log.txt containing the search string.

For /f loops through each line the command inside (...) generates.

As echo > log-time.txt (single > !) overwrites log-time.txt every time it's executed, only the last matching line remains in log-time.txt

All below options worked for me.

Option 1: Annotation for FIELD at class & field level with getter/setter methods

 @XmlRootElement(name = "fields")
 @XmlAccessorType(XmlAccessType.FIELD)
    public class Fields {

        @XmlElement(name = "field")
        List<Field> fields = new ArrayList<Field>();
            //getter, setter
    }

Option 2: No Annotation for FIELD at class level(@XmlAccessorType(XmlAccessType.FIELD) and with only getter method. Adding Setter method will throw the error as we are not including the Annotation in this case. Remember, setter is not required when you explicitly set the values in your XML file.

@XmlRootElement(name = "fields")
    public class Fields {

        @XmlElement(name = "field")
        List<Field> fields = new ArrayList<Field>();
            //getter
    }

Option 3: Annotation at getter method alone. Remember we can also use the setter method here as we are not doing any FIELD level annotation in this case.

@XmlRootElement(name = "fields")
    public class Fields {

        List<Field> fields = new ArrayList<Field>();

        @XmlElement(name = "field")
        //getter

        //setter
    }

DataTable myCustomers = myDataset.Tables["Customers"];
DataRow currentRow = null;
for (int i = 0; i < myCustomers.Rows.Count; i++)
{
    currentRow = myCustomers.Rows[i];
    listBox1.Items.Add(string.Format("{0} is {1} YEARS OLD", currentRow["Name"], currentRow["Age"]));    
}

Of course it does:

@Html.TextBoxFor(x => x.Email, new { @placeholder = "Email" })

@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;
}

Use this:

Button loginBtn = view.findViewById(R.id.loginBtn);
loginBtn.setOnClickListener(new View.OnClickListener() {
   public void onClick(View v) {
      InputMethodManager imm = (InputMethodManager) getActivity().getSystemService(getActivity().INPUT_METHOD_SERVICE);
      imm.hideSoftInputFromWindow(v.getWindowToken(), 0);
   }
});

ASP.NET Technical Articles

SUMMARY: In ASP.NET, every Web page derives from the System.Web.UI.Page class. The Page class aggregates an instance of the HttpSession object for session data. The Page class exposes different events and methods for customization. In particular, the OnInit method is used to set the initialize state of the Page object. If the request does not have the Session cookie, a new Session cookie will be issued to the requester.

EDIT:

Session: A Concept for Beginners

SUMMARY: Session is created when user sends a first request to the server for any page in the web application, the application creates the Session and sends the Session ID back to the user with the response and is stored in the client machine as a small cookie. So ideally the "machine that has disabled the cookies, session information will not be stored".

If you have many cases and do not want to write a ton of strcmp() calls, you could do something like:

switch(my_hash_function(the_string)) {
    case HASH_B1: ...
    /* ...etc... */
}

You just have to make sure your hash function has no collisions inside the set of possible values for the string.

In NuGet 3.0 the Get-Package command is deprecated and replaced with Find-Package command.

Find-Package Common.Logging -AllVersions

See the NuGet command reference docs for details.

This is the message shown if you try to use Get-Package in Visual Studio 2015.

This Command/Parameter combination has been deprecated and will be removed
in the next release. Please consider using the new command that replaces it: 
'Find-Package [-Id] -AllVersions'

Or as @Yishai said, you can use the version number dropdown in the NuGet screen in Visual Studio.

Check it's value property:

In jQuery (since your tag mentions it):

$('#fileInput').val()

Or in vanilla JavaScript:

document.getElementById('myFileInput').value

If you want to get rid of it entirely, I've adjusted the code in the previous answers so it works on hover, active and focus too:

input:-webkit-autofill, input:-webkit-autofill:hover, input:-webkit-autofill:active, input:-webkit-autofill:focus {
    -webkit-box-shadow: 0 0 0 1000px white inset;
}

In PostgreSQL there is no merge command, and actually writing it is not trivial - there are actually strange edge cases that make the task "interesting".

The best (as in: working in the most possible conditions) approach, is to use function - such as one shown in manual (merge_db).

If you don't want to use function, you can usually get away with:

updated = db.execute(UPDATE ... RETURNING 1)
if (!updated)
  db.execute(INSERT...)

Just remember that it is not fault proof and it will fail eventually.

$cookie_name = "my cookie";
$cookie_value = "my value";
$cookie_new_value = "my new value";

// Create a cookie,
setcookie($cookie_name, $cookie_value , time() + (86400 * 30), "/"); //86400 = 24 hours in seconds

// Get value in a cookie,
$cookie_value = $_COOKIE[$cookie_name];

// Update a cookie,
setcookie($cookie_name, $cookie_new_value , time() + (86400 * 30), "/");

// Delete a cookie,
setcookie($cookie_name, '' , time() - 3600, "/"); //  time() - 3600 means, set the cookie expiration date to the past hour.

Try the value property, like this:

var fu1 = document.getElementById("FileUpload1");
alert("You selected " + fu1.value);

NOTE: It looks like FileUpload1 is an ASP.Net server-side FileUpload control.
If so, you should get its ID using the ClientID property, like this:

var fu1 = document.getElementById("<%= FileUpload1.ClientID %>");

you should use tagName property and attr('type') for inputs

I found this page when I was trying to set the backgroundImage attribute of a div, but hadn't wrapped the backgroundImage value with url(). This worked fine:

for (var i=0; i<20; i++) {
  // add a wrapper around an image element
  var wrapper = document.createElement('div');
  wrapper.className = 'image-cell';

  // add the image element
  var img = document.createElement('div');
  img.className = 'image';
  img.style.backgroundImage = 'url(http://via.placeholder.com/350x150)';

  // add the image to its container; add both to the body
  wrapper.appendChild(img);
  document.body.appendChild(wrapper);
}

x86 is a 32 bit instruction set, x86_64 is a 64 bit instruction set... the difference is simple architecture. in case of windows os you better use the x86/32bit version for compatibility issues. in case of Linux you will not be able to use a 64 bit s/w if the os does not have the long mode flag.

Whatever I recommend if you have a windows 7 32 bit OS then go for 32bit or x86 binaries and as for Ubuntu 12.04 use command uname -a or grep lm /proc/cpuinfo (grep lm /proc/cpuinfo does not return value for 32 bit as 32 bit os does not has the cpuinfo flag) to know the architecture OS your OS then use the binaries according to your OS.

** Note. Remember you can always install 64 bit os in 32 bit system as long as it supports enhanced 64 bit.. 64 bit os works better some times for multi purpose work and also supports more ram than 32bits. also you can install 32bit s/w in 64 bit os..

** OS = Operating system.

all you have to do is: 1. open site manager on filezilla 2. add new site 3. give host address and port if port is not default port 4. communnication type: SFTP 5. session type key file 6. put username 7. choose key file directory but beware on windows file explorer looks for ppk file as default choose all files on dropdown then choose your pem file and you are good to go.

since you add new site and configured next time when you want to connect just choose your saved site and connect. That is it.

if you have nested panels then you may also need to specify which ones by adding another class name to distinguish between them and add this to the a selector in the above JavaScript

You can use JavaScripts Fetch API (available in your browser) to make network requests.

If using node, you will need to install the node-fetch package.

const url = "https://api.wit.ai/message?v=20140826&q=";

const options = {
  headers: {
    Authorization: "Bearer 6Q************"
  }
};

fetch(url, options)
  .then( res => res.json() )
  .then( data => console.log(data) );

You can use wc -l to figure out the total # of lines.

You can then combine head and tail to get at the range you want. Let's assume the log is 40,000 lines, you want the last 1562 lines, then of those you want the first 838. So:

tail -1562 MyHugeLogFile.log | head -838 | ....

Or there's probably an easier way using sed or awk.

conio.h is a C header file used in old MS-DOS compilers to create text user interfaces. Compilers that targeted non-DOS operating systems, such as Linux, Win32 and OS/2, provided different implementations of these functions.

The #include <curses.h> will give you almost all the functionalities that was provided in conio.h

nucurses need to be installed at the first place

[Update Sep 2016]: This answer was intended for docker compose file v1 (as shown by the sample compose file below). For v2, see the other answer by @Windsooon.

[Original answer]:

It is pretty clear in the documentation. depends_on decides the dependency and the order of container creation and links not only does these, but also

Containers for the linked service will be reachable at a hostname identical to the alias, or the service name if no alias was specified.

For example, assuming the following docker-compose.yml file:

web:
  image: example/my_web_app:latest
  links:
    - db
    - cache

db:
  image: postgres:latest

cache:
  image: redis:latest

With links, code inside web will be able to access the database using db:5432, assuming port 5432 is exposed in the db image. If depends_on were used, this wouldn't be possible, but the startup order of the containers would be correct.

They do this with some basic javascript, but this does not actually hide your HTML source! In many browsers you can simply go to view->source on the menu. Even if you couldn't, it is trivial to simply load up a debugging proxy like Fiddler, or packet-sniff the connection.

It is impossible to effectively hide the HTML, JavaScript, or any other resource sent to the client. Impossible, and isn't all that useful either.

Furthermore, don't try to disable right-click, as there are many other items on that menu (such as print!) that people use regularly.

If ctrl+c doesn't respond right away because your script is too long/complex, hold it.

The break command doesn't run when matlab is executing some of its deeper scripts, and either it won't log a ctrl sequence in the buffer, or it clears the buffer just before or just after it completes those pieces of code. In either case, when matlab returns to execute more of your script, it will recognize that you are holding ctrl+c and terminate.

For longer running programs, I usually try to find a good place to provide a status update and I always accompany that with some measure of time using tic and toc. Depending on what I am doing, I might use run time, segment time, some kind of average, etc...

For really long running programs, I found this to be exceptionally useful http://www.mathworks.com/matlabcentral/fileexchange/16649-send-text-message-to-cell-phone/content/send_text_message.m

but it looks like they have some newer functions for this too.

Since 2019, Array.prototype.flatMap is a good option.

images.flatMap(({src}) => src.endsWith('.json') ? [] : src);

From MDN:

flatMap can be used as a way to add and remove items (modify the number of items) during a map. In other words, it allows you to map many items to many items (by handling each input item separately), rather than always one-to-one. In this sense, it works like the opposite of filter. Simply return a 1-element array to keep the item, a multiple-element array to add items, or a 0-element array to remove the item.

The correct script for postgres (Ubuntu) is:

COPY (SELECT * FROM tbl) TO '/var/lib/postgres/myfile1.csv';

I had a similar warning/error/failure when I was simply trying to make an executable from two different object files (main.o and add.o). I was using the command:

gcc -o exec main.o add.o

But my program is a C++ program. Using the g++ compiler solved my issue:

g++ -o exec main.o add.o

I was always under the impression that gcc could figure these things out on its own. Apparently not. I hope this helps someone else searching for this error.

window.open('http://somelocation.com','mywin','width=500,height=500');

From Business Intelligence Studio:

File->New Project->Integration Services Project

Now in solution explorer there is a SSIS Packages folder, right click it and select "Add Existing Package", and there will be a drop down that can be changed to File System, and the very bottom box allows you to browse to the file. Note that this will copy the file from where ever it is into the project's directory structure.

The filter function can also provide an interesting solution:

result = list(filter(lambda x: x.count(1) > 0, a))

which searches the tuples in the list a for any occurrences of 1. If the search is limited to the first element, the solution can be modified into:

result = list(filter(lambda x: x[0] == 1, a))

Choice one! But the first is very simple. The last maybe util for file manipulation:

//Method 1 (I like this)
File.AppendAllLines(
    "FileAppendAllLines.txt", 
    new string[] { "line1", "line2", "line3" });

//Method 2
File.AppendAllText(
    "FileAppendAllText.txt",
    "line1" + Environment.NewLine +
    "line2" + Environment.NewLine +
    "line3" + Environment.NewLine);

//Method 3
using (StreamWriter stream = File.AppendText("FileAppendText.txt"))
{
    stream.WriteLine("line1");
    stream.WriteLine("line2");
    stream.WriteLine("line3");
}

//Method 4
using (StreamWriter stream = new StreamWriter("StreamWriter.txt", true))
{
    stream.WriteLine("line1");
    stream.WriteLine("line2");
    stream.WriteLine("line3");
}

//Method 5
using (StreamWriter stream = new FileInfo("FileInfo.txt").AppendText())
{
    stream.WriteLine("line1");
    stream.WriteLine("line2");
    stream.WriteLine("line3");
}

final long usedMemInMB=(runtime.totalMemory() - runtime.freeMemory()) / 1048576L;
final long maxHeapSizeInMB=runtime.maxMemory() / 1048576L;
final long availHeapSizeInMB = maxHeapSizeInMB - usedMemInMB;

It is a strange code. It return MaxMemory - (totalMemory - freeMemory). If freeMemory equals 0, then the code will return MaxMemory - totalMemory, so it can more or equals 0. Why freeMemory not used?

Extra info:

If you are using PhpStorm as IDE, after updating the path variable you need to restart PhpStorm so that it takes effect.

Restarting terminal window was not enough for me. (PhpStorm 2020.3.2)

You can go with @greenAfrican example, if it's possible for you to rewrite your function. But if you don't want to rewrite your function, you can wrap it into anonymous function inside apply, like this:

>>> def fxy(x, y):
...     return x * y

>>> df['newcolumn'] = df.apply(lambda x: fxy(x['A'], x['B']), axis=1)
>>> df
    A   B  newcolumn
0  10  20        200
1  20  30        600
2  30  10        300

Finding the first occurrence

There's a recipe for that in itertools:

def first_true(iterable, default=False, pred=None):
    """Returns the first true value in the iterable.

    If no true value is found, returns *default*

    If *pred* is not None, returns the first item
    for which pred(item) is true.

    """
    # first_true([a,b,c], x) --> a or b or c or x
    # first_true([a,b], x, f) --> a if f(a) else b if f(b) else x
    return next(filter(pred, iterable), default)

For example, the following code finds the first odd number in a list:

>>> first_true([2,3,4,5], None, lambda x: x%2==1)
3  

I used this regex expression:

    string s = "søme string";
    Regex regex = new Regex(@"[^a-zA-Z0-9\s]", (RegexOptions)0);
    return regex.Replace(s, "");

You've got what rebase does backwards. git rebase master does what you're asking for — takes the changes on the current branch (since its divergence from master) and replays them on top of master, then sets the head of the current branch to be the head of that new history. It doesn't replay the changes from master on top of the current branch.

This works if the value contains a space:

FOR /F "skip=2 tokens=1,2*" %%A IN ('REG QUERY "%KEY_NAME%" /v "%VALUE_NAME%" 2^>nul') DO (
    set ValueName=%%A
    set ValueType=%%B
    set ValueValue=%%C
)

if defined ValueName (
    echo Value Name = %ValueName%
    echo Value Type = %ValueType%
    echo Value Value = %ValueValue%
) else (
    @echo "%KEY_NAME%"\"%VALUE_NAME%" not found.
)

It depends on number of entities which are going to be updated, if you have large number of entities using JPA Query Update statement is better as you dont have to load all the entities from database, if you are going to update just one entity then using find and update is fine.

Settings for compiler

In the project where you want to #include the header file from another project, you will need to add the path of the header file into the Additional Include Directories section in the project configuration.

To access the project configuration:

1. Right-click on the project, and select Properties.
2. Select Configuration Properties->C/C++->General.
3. Set the path under Additional Include Directories.

How to include

To include the header file, simply write the following in your code:

#include "filename.h"

Note that you don't need to specify the path here, because you include the directory in the Additional Include Directories already, so Visual Studio will know where to look for it.

If you don't want to add every header file location in the project settings, you could just include a directory up to a point, and then #include relative to that point:

// In project settings
Additional Include Directories    ..\..\libroot

// In code
#include "lib1/lib1.h"    // path is relative to libroot
#include "lib2/lib2.h"    // path is relative to libroot

Setting for linker

If using static libraries (i.e. .lib file), you will also need to add the library to the linker input, so that at linkage time the symbols can be linked against (otherwise you'll get an unresolved symbol):

1. Right-click on the project, and select Properties.
2. Select Configuration Properties->Linker->Input
3. Enter the library under Additional Dependencies.

In 2015, if you still getting this confusing error, blame python default setuptools that PIP uses.

1. Download and install minimal Microsoft Visual C++ Compiler for Python 2.7 required to compile python 2.7 modules from http://www.microsoft.com/en-in/download/details.aspx?id=44266
2. Update your setuptools - pip install -U setuptools
3. Install whatever python package you want that require C compilation. pip install blahblah

It will work fine.

UPDATE: It won't work fine for all libraries. I still get some error with few modules, that require lib-headers. They only thing that work flawlessly is Linux platform

Another way is,

mysql > SHOW CREATE TABLE my_db.my_table;

You should get the table name and create table sql

we can also use interface for same as broadcastManger here i am sharing the testd code for broadcastManager but by interface.

first make an interface like:

public interface MyInterface {
     void GetName(String name);
}

2-this is the first class that need implementation

public class First implements MyInterface{

    MyInterface interfc;    
    public static void main(String[] args) {
      First f=new First();      
      Second s=new Second();
      f.initIterface(s);
      f.GetName("Paddy");
  }
  private void initIterface(MyInterface interfc){
    this.interfc=interfc;
  }
  public void GetName(String name) {
    System.out.println("first "+name);
    interfc.GetName(name);  
  }
}

3-here is the the second class that implement the same interface whose method call automatically

public class Second implements MyInterface{
   public void GetName(String name) {
     System.out.println("Second"+name);
   }
}

so by this approach we can use the interface functioning same as broadcastManager.

IN ECLIPSE LUNA I ve resolved this issue by using contet menu on my Project : ANdroid Tools > Add support Library ...

Sometimes all you need is to push again. It happen to me today due to slow internet connection(when you are downloading or using p2p).

Please see screenshot below:

Use Docker CE app

macOS

Use the new Docker Community Edition app for macOS. For example:

1. Uninstall all Docker Homebrew packages which you've installed so far:

   brew uninstall docker-compose
   brew uninstall docker-machine
   brew uninstall docker
   

2. Install an app manually or via Homebrew-Cask:

   brew cask install docker
   

   ^{Note: This app will create necessary links to docker, docker-compose, docker-machine, etc.}

3. After running the app, checkout the a Docker whale icon in the status menu.

4. Now you should be able to use docker, docker-compose, docker-machine commands as usual in the Terminal.

Related:

• Brew install docker does not include docker engine?
• Cannot connect to the Docker daemon on macOS

You can use the following function to subtract 1 or any years from a date.

 function yearstodate($years) {

        $now = date("Y-m-d");
        $now = explode('-', $now);
        $year = $now[0];
        $month   = $now[1];
        $day  = $now[2];
        $converted_year = $year - $years;
        echo $now = $converted_year."-".$month."-".$day;

    }

$number_to_subtract = "1";
echo yearstodate($number_to_subtract);

And looking at above examples you can also use the following

$user_age_min = "-"."1";
echo date('Y-m-d', strtotime($user_age_min.'year'));

You'll need to use an Iterator to loop through the keys to get their values.

Here's a Kotlin implementation, you will realised that the way I got the string is using optString(), which is expecting a String or a nullable value.

val keys = jsonObject.keys()
while (keys.hasNext()) {
    val key = keys.next()
    val value = targetJson.optString(key)        
}

There might be a lot of reasons behind the blank screen without errors. I have faced this problem many times whenever I want to upload laravel project in shared hosting.

Reason: Incorrect PHP Version

In my case, issue was because of incorrect php version. I had php 7.1 version in local computer where as in shared hosting cpanel, there was php 5.6 version. Switching up the version from 5.6 to 7.1 worked for me.

You can change php version in cpanel from multiphp manager available in cpanel home page.

func Contain(target interface{}, list interface{}) (bool, int) {

        for i := 0; i < listvalue.Len(); i++ {
            if target == listvalue.Index(i).Interface() {
                return true, i
            }

some dynamic situation holder.edit_pin.setInputType(InputType.TYPE_CLASS_NUMBER); will not work so better use both like that

holder.edit_pin.setInputType(InputType.TYPE_CLASS_NUMBER);
holder.edit_pin.setTransformationMethod(PasswordTransformationMethod.getInstance());

Note : this is suitable for when you are using dynamic controls like using arrayaapter

Ok for all of you out there that arrived here in desperation searching for the same problem. I hope you will find this quicker then I did ;O.

This is how it is solved. JoostK told me at github that "the first argument to join is the table (or data) you're joining.". And he was right.

Here is the code. Different table and names but you will get the idea right? It t

DB::table('users')
        ->select('first_name', 'TotalCatches.*')

        ->join(DB::raw('(SELECT user_id, COUNT(user_id) TotalCatch,
               DATEDIFF(NOW(), MIN(created_at)) Days,
               COUNT(user_id)/DATEDIFF(NOW(), MIN(created_at))
               CatchesPerDay FROM `catch-text` GROUP BY user_id)
               TotalCatches'), 
        function($join)
        {
           $join->on('users.id', '=', 'TotalCatches.user_id');
        })
        ->orderBy('TotalCatches.CatchesPerDay', 'DESC')
        ->get();

Date has the time as well, just add HH:mm:ss to the date format:

import java.text.SimpleDateFormat
def date = new Date()
def sdf = new SimpleDateFormat("MM/dd/yyyy HH:mm:ss")
println sdf.format(date)

In case you are using JRE 8 you can use LoaclDateTime:

import java.time.*

LocalDateTime t = LocalDateTime.now();
return t as String

On a side note, in PowerShell 3.0 you can use the Get-Content cmdlet with the new Raw switch:

$text = Get-Content .\file.txt -Raw 

You can check for type of a variable using __name__ of a type.

Ex:

>>> a = [1,2,3,4]  
>>> b = 1  
>>> type(a).__name__
'list'
>>> type(a).__name__ == 'list'
True
>>> type(b).__name__ == 'list'
False
>>> type(b).__name__
'int'

It was not clear to me in the question if ts.tax_status_code is a primary or alternate key or not. Same thing with recipient_code. This would be useful to know.

You can deal with the possibility of your bind variable being null using an OR as follows. You would bind the same thing to the first two bind variables.

If you are concerned about performance, you would be better to check if the values you intend to bind are null or not and then issue different SQL statement to avoid the OR.

insert into account_type_standard 
(account_type_Standard_id, tax_status_id, recipient_id)
(
select 
   account_type_standard_seq.nextval,
   ts.tax_status_id, 
   r.recipient_id
from tax_status ts, recipient r
where (ts.tax_status_code = ? OR (ts.tax_status_code IS NULL and ? IS NULL))
and (r.recipient_code = ? OR (r.recipient_code IS NULL and ? IS NULL))

As Matt Johnson said

If you can limit your usage to modern web browsers, you can now do the following without any special libraries:

new Date().toLocaleString("en-US", {timeZone: "America/New_York"})

This isn't a comprehensive solution, but it works for many scenarios that require only output conversion (from UTC or local time to a specific time zone, but not the other direction).

So although the browser can not read IANA timezones when creating a date, or has any methods to change the timezones on an existing Date object, there seems to be a hack around it:

function changeTimezone(date, ianatz) {

  // suppose the date is 12:00 UTC
  var invdate = new Date(date.toLocaleString('en-US', {
    timeZone: ianatz
  }));

  // then invdate will be 07:00 in Toronto
  // and the diff is 5 hours
  var diff = date.getTime() - invdate.getTime();

  // so 12:00 in Toronto is 17:00 UTC
  return new Date(date.getTime() - diff); // needs to substract

}

// E.g.
var here = new Date();
var there = changeTimezone(here, "America/Toronto");

console.log(`Here: ${here.toString()}\nToronto: ${there.toString()}`);

Unfortunately the answers given so far (including the most voted) are either "just" common sense, plain wrong or confusing at best. None of crucial keywords¹ pop up!

I wrote 3 answers:

1. This explanation (start here).
2. Concrete answers to OP’s questions.
3. Improved detailed HTML.

To understand the role of the html elements discussed here you have to know that some of them section the document. Each and every html document can be sectioned according to the HTML5 outline algorithm for the purpose of creating an outline—⁠or⁠—table of contents (TOC). The outline is not generally visible (these days), but authors should use html in such a way that the resulting outline reflects their intentions.

You can create sections with exactly these elements and nothing else:

• creating (explicit) subsections
  • <section> sections
  • <article> sections
  • <nav> sections
  • <aside> sections
• creating sibling sections or subsections
  • sections of unspecified type with <h*>² (not all do this, see below)
• to level up close the current explicit (sub)section

Sections can be named:

• <h*> created sections name themselves
• <section|article|nav|aside> sections will be named by the first <h*> if there is one
  • these <h*> are the only ones which don’t create sections themselves

There is one more thing to sections: the following contexts (i.e. elements) create "outline boundaries". Whatever sections they contain is private to them:

• the document itself with <body>
• table cells with <td>
• <blockquote>
• <details>, <dialog>, <fieldset>, and <figure>
• nothing else

example HTML
<body> <h3>if you want siblings at top level...</h3> <h3>...you have to use untyped sections with <h*>...</h3> <article> <h1>...as any other section will descent</h1> </article> <nav> <ul> <li><a href=...>...</a></li> </ul> </nav> </body> has this outline
1. if you want siblings at top level... 2. ...you have to use untyped sections with <h*>... 2.1. ...as any other section will descent 2.2. (unnamed navigation)

This raises two questions:

What is the difference between <article> and <section>?

• both can:
  • be nested in each other
  • take a different notion in a different context or nesting level
• <section>s are like book chapters
  • they usually have siblings (maybe in a different document?)
  • together they have something in common, like chapters in a book
• one author, one <article>, at least on the lowest level
  • standard example: a single blog comment
  • a blog entry itself is also a good example
  • a blog entry <article> and its comment <article>s could also be wrapped with an <article>
  • it’s some "complete" thing, not a part in a series of similar
• <section>s in an <article> are like chapters in a book
• <article>s in a <section> are like poems in a volume (within a series)

How do <header>, <footer> and <main> fit in?

• they have zero influence on sectioning
• <header> and <footer>
  • they allow you to mark zones of each and every section
  • even within a section you can have them several times
  • to differentiate from the main part in this section
  • limited only by the author’s taste
  • <header>
    • may mark the title/name of this section
    • may contain a logo for this section
    • has no need to be at the top or upper part of the section
  • <footer>
    • may mark the credits/author of this section
    • can come at the top of the section
    • can even be above a <header>
• <main>
  • only allowed once
  • marks the main part of the top level section (i.e. the document, <body> that is)
  • subsections themselves have no markup for their main part
  • <main> can even “hide” in some subsections of the document, while document’s <header> and <footer> can’t (that markup would mark header/footer of that subsection then)
    • but it is not allowed in <article> sections³
  • helps to distinguish “the real thing” from document’s non-header, non-footer, non-main content, if that makes sense in your case...
    

^{1 to mind comes: outline, algorithm, implicit sectioning
2 I use <h*> as shorthand for <h1>, <h2>, <h3>, <h4>, <h5> and <h6>
3 neither is <main> allowed in <aside> or <nav>, but that is of no surprise. – In effect: <main> can only hide in (nested) descending <section> sections or appear at top level, namely <body>}

I had the same problem, and found a detailed explanation in http://www.webmasterworld.com/apache/3163397.htm

My solution (the subdomains contents should be in a folder called sd_subdomain:

Options +FollowSymLinks -MultiViews

RewriteEngine On
RewriteBase /

RewriteCond %{HTTP_HOST} !^www\.
RewriteCond %{HTTP_HOST} subdomain\.domain\.com
RewriteCond $1 !^sd_
RewriteRule (.*) /sd_subdomain/$1 [L]

The Reason is that your previous build is still running in the background. I solve this problem by following these steps:

• Open Task Manager
• Goto Details Tab
• Find Your Application
• End Task it by right clicking on it
• Done!

Update: See rdlowrey's update below regarding the use of fwrite(STDERR, print_r($myDebugVar, TRUE)); as a much simpler work around

This behaviour is intentional (as jasonbar has pointed out). The conflicting state of the manual has been reported to PHPUnit.

A work-around is to have PHPUnit assert the expected output is empty (when infact there is output) which will trigger the unexpected output to be shown.

class theTest extends PHPUnit_Framework_TestCase
{
    /**
     * @outputBuffering disabled
     */
    public function testOutput() {
        $this->expectOutputString(''); // tell PHPUnit to expect '' as output
        print_r("Hello World");
        print "Ping";
        echo "Pong";
        $out = "Foo";
        var_dump($out);
    }   
}

gives:

I have same idea with user KM. but do not need extra table Number. Just this function only.

CREATE FUNCTION [dbo].[FN_ListToTable]
(
    @SplitOn              char(1)              --REQUIRED, the character to split the @List string on
   ,@List                 varchar(8000)        --REQUIRED, the list to split apart
)
RETURNS
@ParsedList table
(
    ListValue varchar(500)
)
AS
BEGIN
    DECLARE @number int = 0
    DECLARE @childString varchar(502) = ''
    DECLARE @lengthChildString int = 0
    DECLARE @processString varchar(502) = @SplitOn + @List + @SplitOn

    WHILE @number < LEN(@processString)
    BEGIN
        SET @number = @number + 1
        SET @lengthChildString = CHARINDEX(@SplitOn, @processString, @number + 1) - @number - 1
        IF @lengthChildString > 0
        BEGIN
            SET @childString = LTRIM(RTRIM(SUBSTRING(@processString, @number + 1, @lengthChildString)))

            IF @childString IS NOT NULL AND @childString != ''
            BEGIN
                INSERT INTO @ParsedList(ListValue) VALUES (@childString)
                SET @number = @number + @lengthChildString - 1
            END
        END
    END

RETURN

END

And here is the test:

SELECT ListValue FROM dbo.FN_ListToTable('/','a/////bb/c')

Result:

Have you verified that there is in fact a row where Staff_Id = @PersonID? What you've posted works fine in a test script, assuming the row exists. If you comment out the insert statement, then the error is raised.

set nocount on

create table Timesheet_Hours (Staff_Id int, BookedHours int, Posted_Flag bit)

insert into Timesheet_Hours (Staff_Id, BookedHours, Posted_Flag) values (1, 5.5, 0)

I was searching an answer for this same question and found ENTRYPOINT in Dockerfile solution for me.

Dockerfile

...
ENTRYPOINT /my-script.sh ; /my-script2.sh ; /bin/bash

Now the scripts are executed when I start the container and I get the bash prompt after the scripts has been executed.

Solution for object and primitive types:

public static final <T> void swap(final T[] arr, final int i, final int j) {
    T tmp = arr[i];
    arr[i] = arr[j];
    arr[j] = tmp;
}
public static final void swap(final boolean[] arr, final int i, final int j) {
    boolean tmp = arr[i];
    arr[i] = arr[j];
    arr[j] = tmp;
}
public static final void swap(final byte[] arr, final int i, final int j) {
    byte tmp = arr[i];
    arr[i] = arr[j];
    arr[j] = tmp;

public static final void swap(final short[] arr, final int i, final int j) {
    short tmp = arr[i];

Just like with nextSibling and nextElementSibling, just remember that, properties with "element" in their name always returns Element or null. Properties without can return any other kind of node.

console.log(document.body.parentNode, "is body's parent node");    // returns <html>
console.log(document.body.parentElement, "is body's parent element"); // returns <html>

var html = document.body.parentElement;
console.log(html.parentNode, "is html's parent node"); // returns document
console.log(html.parentElement, "is html's parent element"); // returns null

If you are willing to use custom table header as table header, try the followings....

Updated for swift 3.0

Step 1

Create UITableViewHeaderFooterView for custom header..

import UIKit

class MapTableHeaderView: UITableViewHeaderFooterView {

    @IBOutlet weak var testView: UIView!

}

Step 2

Add custom header to UITableView

    override func viewDidLoad() {
            super.viewDidLoad()

            tableView.delegate = self
            tableView.dataSource = self

            //register the header view

            let nibName = UINib(nibName: "CustomHeaderView", bundle: nil)
            self.tableView.register(nibName, forHeaderFooterViewReuseIdentifier: "CustomHeaderView")


    }

    extension BranchViewController : UITableViewDelegate{

    }

    extension BranchViewController : UITableViewDataSource{

        func tableView(_ tableView: UITableView, heightForHeaderInSection section: Int) -> CGFloat {
            return 200
        }

        func tableView(_ tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {
            let headerView = self.tableView.dequeueReusableHeaderFooterView(withIdentifier: "CustomHeaderView" ) as! MapTableHeaderView

            return headerView
        }

        func tableView(_ tableView: UITableView, numberOfRowsInSection section: 

    Int) -> Int {
            // retuen no of rows in sections
        }

        func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell { 
            // retuen your custom cells    
        }

        func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {

        }

        func numberOfSections(in tableView: UITableView) -> Int {
            // retuen no of sections
        }

        func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
            // retuen height of row
        }


    }

Use StringTokenizer to parse the string.

String s ="SALES:0,SALE_PRODUCTS:1,EXPENSES:2,EXPENSES_ITEMS:3";
    Map<String, Integer> lMap=new HashMap<String, Integer>();


    StringTokenizer st=new StringTokenizer(s, ",");
    while(st.hasMoreTokens())
    {
        String [] array=st.nextToken().split(":");
        lMap.put(array[0], Integer.valueOf(array[1]));
    }

Dependency between async javascript calls.

Another good example of how yield can be used.

function request(url) {_x000D_
  axios.get(url).then((reponse) => {_x000D_
    it.next(response);_x000D_
  })_x000D_
}_x000D_
_x000D_
function* main() {_x000D_
  const result1 = yield request('http://some.api.com' );_x000D_
  const result2 = yield request('http://some.otherapi?id=' + result1.id );_x000D_
  console.log('Your response is: ' + result2.value);_x000D_
}_x000D_
_x000D_
var it = main();_x000D_
it.next()

Extract Day, Month and Year

The highest voted function and the accepted one do NOT work locale-independently since the DATE command is subject to localization too. For example (the accepted one): In English you have YYYY for year and in Holland it is JJJJ. So this is a no-go. The following script takes the users' localization from the registry, which is locale-independent.

@echo off

::: Begin set date
setlocal EnableExtensions EnableDelayedExpansion

:: Determine short date format (independent from localization) from registry
for /f "skip=1 tokens=3-5 delims=- " %%L in ( '2^>nul reg query "HKCU\Control Panel\International" /v "sShortDate"' ) do ( 

    :: Since we can have multiple (short) date formats we only use the first char from the format in a new variable
    set "_L=%%L" && set "_L=!_L:~0,1!" && set "_M=%%M" && set "_M=!_M:~0,1!" && set "_N=%%N" && set "_N=!_N:~0,1!"

    :: Now assign the date values to the new vars
    for /f "tokens=2-4 delims=/-. " %%D in ( "%date%" ) do ( set "!_L!=%%D" && set "!_M!=%%E" && set "!_N!=%%F" )
)


:: Print the values as is
echo.
echo This is the original date string --^> %date%
echo These are the splitted values    --^> Day: %d%, Month:%m%, Year: %y%.
echo.

endlocal

Extract only the Year

For a script I wrote I wanted only to extract the year (locale-independent) so I came up with this oneliner as I couldn't find any solution. It uses the 'DATE' var, multiple delimiters and checks for a number greater than 31. That then will be the current year. It's low on resources in contrast to some of the other solutions.

@echo off

setlocal EnableExtensions

for /f " tokens=2-4 delims=-./ " %%D in ( "%date%" ) do ( if %%D gtr 31 ( set "_YEAR=%%D" ) else ( if %%E gtr 31 ( set "_YEAR=%%E" ) else ( if %%F gtr 31 ( set "_YEAR=%%F" ) ) ) )

echo And the year is... %_YEAR%.
echo.

endlocal

According to the documentation. You can use:

$locationProvider.html5Mode(true).hashPrefix('!');

NB: If your browser does not support to HTML 5. Dont worry :D it have fallback to hashbang mode. So, you don't need to check with if(window.history && window.history.pushState){ ... } manually

For example: If you click: <a href="/other">Some URL</a>

In HTML5 Browser: angular will automatically redirect to example.com/other

In Not HTML5 Browser: angular will automatically redirect to example.com/#!/other

In mdcharm it is like this:

* [Descripción](#descripcion)
* [Funcionamiento](#funcionamiento)
* [Instalación](#instalacion)
* [Configuración](#configuracion)

### Descripción {#descripcion}
### Funcionamiento {#funcionamiento}
### Instalación {#instalacion}
### Configuración {#configuracion}

Right-click on your project's name in Eclipse's Project Explorer, then click Run As followed by Run on Server. Click the Next button. Make sure your project's name is listed in the Configured: column on the right. If it is, then you should be able to access it with this URL:

http://localhost:8085/projectname/

Additionally, whenever you make new additions (such as new JSPs, graphics or other resources) to your project, be sure to refresh the project by clicking on its name and then hitting F5. Otherwise Eclipse does not know that those new resources are available and will not make them available to Tomcat to serve.

This is what worked for me. I am not sure why the syntax is different, But it was extremely frustrating trying every combination of activate, inactive, deactivated, disabled, etc. In lower case upper case in quotes out of quotes in brackets out of brackets etc. Well, here's the winning combination for me, for some reason.. different than everyone else?

import tkinter

class App(object):
    def __init__(self):
        self.tree = None
        self._setup_widgets()

    def _setup_widgets(self):
        butts = tkinter.Button(text = "add line", state="disabled")
        butts.grid()

def main():  
    root = tkinter.Tk()
    app = App()
    root.mainloop()

if __name__ == "__main__":
    main()

If you want to know on which platform you are on out of "Linux", "Windows", or "Darwin" (Mac), without more precision, you should use:

>>> import platform
>>> platform.system()
'Linux'  # or 'Windows'/'Darwin'

The platform.system function uses uname internally.

Yes, it is possible:

jQuery.now()

or simply

$.now()

see jQuery Documentation for jQuery.now()

Minimalistic Solution

Here is a "minimal" solution.

class SortedArrayList<T> extends ArrayList<T> {

    @SuppressWarnings("unchecked")
    public void insertSorted(T value) {
        add(value);
        Comparable<T> cmp = (Comparable<T>) value;
        for (int i = size()-1; i > 0 && cmp.compareTo(get(i-1)) < 0; i--)
            Collections.swap(this, i, i-1);
    }
}

The insert runs in linear time, but that would be what you would get using an ArrayList anyway (all elements to the right of the inserted element would have to be shifted one way or another).

Inserting something non-comparable results in a ClassCastException. (This is the approach taken by PriorityQueue as well: A priority queue relying on natural ordering also does not permit insertion of non-comparable objects (doing so may result in ClassCastException).)

Overriding List.add

Note that overriding List.add (or List.addAll for that matter) to insert elements in a sorted fashion would be a direct violation of the interface specification. What you could do, is to override this method to throw an UnsupportedOperationException.

From the docs of List.add:

boolean add(E e)
    Appends the specified element to the end of this list (optional operation).

Same reasoning applies for both versions of add, both versions of addAll and set. (All of which are optional operations according to the list interface.)

Some tests

SortedArrayList<String> test = new SortedArrayList<String>();

test.insertSorted("ddd");    System.out.println(test);
test.insertSorted("aaa");    System.out.println(test);
test.insertSorted("ccc");    System.out.println(test);
test.insertSorted("bbb");    System.out.println(test);
test.insertSorted("eee");    System.out.println(test);

....prints:

[ddd]
[aaa, ddd]
[aaa, ccc, ddd]
[aaa, bbb, ccc, ddd]
[aaa, bbb, ccc, ddd, eee]

You want to do $arrayOfString[0].Title -eq $myPbiject.item(0).Title

-match is for regex matching ( the second argument is a regex )

Ahhhh, now it is clear. You seem to have problems binding back the value. Not with displaying it on the view. Indeed, that's the fault of the default model binder. You could write and use a custom one that will take into consideration the [DisplayFormat] attribute on your model. I have illustrated such a custom model binder here: https://stackoverflow.com/a/7836093/29407

Apparently some problems still persist. Here's my full setup working perfectly fine on both ASP.NET MVC 3 & 4 RC.

Model:

public class MyViewModel
{
    [DisplayName("date of birth")]
    [DataType(DataType.Date)]
    [DisplayFormat(DataFormatString = "{0:dd/MM/yyyy}", ApplyFormatInEditMode = true)]
    public DateTime? Birth { get; set; }
}

Controller:

public class HomeController : Controller
{
    public ActionResult Index()
    {
        return View(new MyViewModel
        {
            Birth = DateTime.Now
        });
    }

    [HttpPost]
    public ActionResult Index(MyViewModel model)
    {
        return View(model);
    }
}

View:

@model MyViewModel

@using (Html.BeginForm())
{
    @Html.LabelFor(x => x.Birth)
    @Html.EditorFor(x => x.Birth)
    @Html.ValidationMessageFor(x => x.Birth)
    <button type="submit">OK</button>
}

Registration of the custom model binder in Application_Start:

ModelBinders.Binders.Add(typeof(DateTime?), new MyDateTimeModelBinder());

And the custom model binder itself:

public class MyDateTimeModelBinder : DefaultModelBinder
{
    public override object BindModel(ControllerContext controllerContext, ModelBindingContext bindingContext)
    {
        var displayFormat = bindingContext.ModelMetadata.DisplayFormatString;
        var value = bindingContext.ValueProvider.GetValue(bindingContext.ModelName);

        if (!string.IsNullOrEmpty(displayFormat) && value != null)
        {
            DateTime date;
            displayFormat = displayFormat.Replace("{0:", string.Empty).Replace("}", string.Empty);
            // use the format specified in the DisplayFormat attribute to parse the date
            if (DateTime.TryParseExact(value.AttemptedValue, displayFormat, CultureInfo.InvariantCulture, DateTimeStyles.None, out date))
            {
                return date;
            }
            else
            {
                bindingContext.ModelState.AddModelError(
                    bindingContext.ModelName,
                    string.Format("{0} is an invalid date format", value.AttemptedValue)
                );
            }
        }

        return base.BindModel(controllerContext, bindingContext);

Now, no matter what culture you have setup in your web.config (<globalization> element) or the current thread culture, the custom model binder will use the DisplayFormat attribute's date format when parsing nullable dates.

You can verify the key length limit:

int maxKeyLen = Cipher.getMaxAllowedKeyLength("AES");
System.out.println("MaxAllowedKeyLength=[" + maxKeyLen + "].");

I used System.Data.Linq.SqlClient.SqlMethods.Like(row.Name, "test") in my query.

This performs a case-insensitive comparison.

adb shell
am start -n com.package.name/com.package.name.ActivityName

Or you can use this directly:

adb shell am start -n com.package.name/com.package.name.ActivityName

You can also specify actions to be filter by your intent-filters:

am start -a com.example.ACTION_NAME -n com.package.name/com.package.name.ActivityName

You can simulate private methods like this:

function Restaurant() {
}

Restaurant.prototype = (function() {
    var private_stuff = function() {
        // Private code here
    };

    return {

        constructor:Restaurant,

        use_restroom:function() {
            private_stuff();
        }

    };
})();

var r = new Restaurant();

// This will work:
r.use_restroom();

// This will cause an error:
r.private_stuff();

I had this issue, as I had copied a (fairly generic) webpage from one of my ASP.Net applications into a new application.

I changed the relevant namespace commands, to reflect the new location of the file... but... I had forgotten to change the Inherits parameter in the aspx page itself.

<%@ Page MasterPageFile="" StylesheetTheme="" Language="C#"
    AutoEventWireup="true" CodeBehind="MikesReports.aspx.cs" 
    Inherits="MikesCompany.MikesProject.MikesReports" %>

Once I had changed the Inherits parameter, the error went away.

To install Python package from github, you need to clone that repository.

git clone https://github.com/jkbr/httpie.git

Then just run the setup.py file from that directory,

sudo python setup.py install

When divided by zero

1. If you divide double by 0, JVM will show Infinity.

   public static void main(String [] args){ double a=10.00; System.out.println(a/0); }
   

   Console: Infinity

2. If you divide int by 0, then JVM will throw Arithmetic Exception.

   public static void main(String [] args){
       int a=10;
       System.out.println(a/0);
   }
   

   Console: Exception in thread "main" java.lang.ArithmeticException: / by zero

Put the code inside a function and it won't run until you call the function. You should have a main function in your main.py. with the statement:

if __name__ == '__main__':
  main()

Then, if you call python main.py the main() function will run. If you import main.py, it will not. Also, you should probably rename main.py to something else for clarity's sake.

Try this:

<tr ng-repeat="player in players | filter:{id: player_id, name:player_name} | filter:ageFilter">

$scope.ageFilter = function (player) {
    return (player.age > $scope.min_age && player.age < $scope.max_age);
}

This is basically Muhammad Saqib's answer except two diffs:

1: Adds width and height function parameters.

2: This is a small nuance which can be ignored... Saying 'As Bitmap', instead of 'As Image'. 'As Image' does work just fine. I just prefer to match Return types. See Image VS Bitmap Class.

Public Shared Function ResizeImage(ByVal InputBitmap As Bitmap, width As Integer, height As Integer) As Bitmap
    Return New Bitmap(InputImage, New Size(width, height))
End Function

Ex.

Dim someimage As New Bitmap("C:\somefile")
someimage = ResizeImage(someimage,800,600)
