Just adding this answer in case others are directed here by Google Search as I was. I used the elevate module in my Python script and the script executed with Administrator Privileges in Windows 10.

It will be better for you to write your code like this.

In your Controller Write this code.

    function new_blank_order_summary() {
     $query = $this->sales_model->order_summary_insert();
     if($query) {
        $this->load->view('sales/new_blank_order_summary'); 
    } else {
        $this->load->view('sales/data_insertion_failed');
    }
  }

and in your Model

function order_summary_insert() {
    $orderLines = trim(xss_clean($this->input->post('orderlines')));
    $customerName = trim(xss_clean($this->input->post('customer')));
    $data = array(
        'OrderLines'=>$orderLines,
        'CustomerName'=>$customerName
    );

    $this->db->insert('Customer_Orders',$data);
    return ($this->db->affected_rows() != 1) ? false : true;
}

According to the spec for locating Schemas

there may or may not be a schema retrievable via the namespace name... User community and/or consumer/provider agreements may establish circumstances in which [trying to retrieve an xsd from the namespace url] is a sensible default strategy

(thanks for being unambiguous, spec!)

and

in case a document author (human or not) created a document with a particular schema in view, and warrants that some or all of the document conforms to that schema, the schemaLocation and noNamespaceSchemaLocation [attributes] are provided.

So basically with specifying just a namespace, your XML "might" be attempted to be validated against an xsd at that location (even if it lacks a schemaLocation attribute), depending on your "community." If you specify a specific schemaLocation, then it basically is implying that the xml document "should" be conformant to said xsd, so "please validate it" (as I read it). My guess is that if you don't do a schemaLocation or noNamespaceSchemaLocation attribute it just "isn't validated" most of the time (based on the other answers, appears java does it this way).

Another wrinkle here is that typically, with xsd validation in java libraries [ex: spring config xml files], if your XML files specifies a particular schemaLocation xsd url in an XML file, like xsi:schemaLocation="http://somewhere http://somewhere/something.xsd" typically within one of your dependency jars it will contain a copy of that xsd file, in its resources section, and spring has a "mapping" capability saying to treat that xsd file as if it maps to the url http://somewhere/something.xsd (so you never end up going to web and downloading the file, it just exists locally). See also https://stackoverflow.com/a/41225329/32453 for slightly more info.

Try to use classpath*: prefix instead.

Also please try to deploy exploded war, to ensure that all files are there.

Yes, safari will detect the *.ipa and will try to install it, but the ipa needs to be correctly signed and only allowed devices would be able to install it.

All of this is for Ad-hoc distribution, not for production apps.

In your Controller

public function updtitle() 
{   
    $data = array(
        'table_name' => 'your_table_name_to_update', // pass the real table name
        'id' => $this->input->post('id'),
        'title' => $this->input->post('title')
    );

    $this->load->model('Updmodel'); // load the model first
    if($this->Updmodel->upddata($data)) // call the method from the model
    {
        // update successful
    }
    else
    {
        // update not successful
    }

}

In Your Model

public function upddata($data) {
    extract($data);
    $this->db->where('emp_no', $id);
    $this->db->update($table_name, array('title' => $title));
    return true;
}

The active record query is similar to

"update $table_name set title='$title' where emp_no=$id"

I also like itertuples()

for row in df.itertuples():
    print(row.A)
    print(row.Index)

since row is a named tuples, if you meant to access values on each row this should be MUCH faster

speed run :

df = pd.DataFrame([x for x in range(1000*1000)], columns=['A'])
st=time.time()
for index, row in df.iterrows():
    row.A
print(time.time()-st)
45.05799984931946

st=time.time()
for row in df.itertuples():
    row.A
print(time.time() - st)
0.48400020599365234

There's also npm install https://github.com/{USER}/{REPO}/tarball/{BRANCH} to use a different branch.

As with many, in my situation I was also getting this because of an error. And sadly I could just read the CSS of the html error page.

The source of my problem was also a rewrite rule on the server. It was rewriting http to https.

You might want Python's UUID functions:

21.15. uuid — UUID objects according to RFC 4122

eg:

import uuid
print uuid.uuid4()

7d529dd4-548b-4258-aa8e-23e34dc8d43d

Try

this.router.navigate([], { 
  queryParams: {
    query: value
  }
});

will work for same route navigation other than single quotes.

You are checking it the array index contains a string "undefined", you should either use the typeof operator:

typeof predQuery[preId] == 'undefined'

Or use the undefined global property:

predQuery[preId] === undefined

The first way is safer, because the undefined global property is writable, and it can be changed to any other value.

According to the Cloudera documentation - What's New in CDH 5.7.0 it includes Spark 1.6.0.

Java 8 style, using the java.time classes:

// Monday, February 29 is a leap day in 2016 (otherwise, February only has 28 days)
LocalDate start = LocalDate.parse("2016-02-28"),
          end   = LocalDate.parse("2016-03-02");

// 4 days between (end is inclusive in this example)
Stream.iterate(start, date -> date.plusDays(1))
        .limit(ChronoUnit.DAYS.between(start, end) + 1)
        .forEach(System.out::println);

Output:

2016-02-28
2016-02-29
2016-03-01
2016-03-02

Alternative:

LocalDate next = start.minusDays(1);
while ((next = next.plusDays(1)).isBefore(end.plusDays(1))) {
    System.out.println(next);
}

Java 9 added the datesUntil() method:

start.datesUntil(end.plusDays(1)).forEach(System.out::println);

'*' works as a modifier for the previous item. So 'abc*def' searches for 'ab' followed by 0 or more 'c's follwed by 'def'.

What you probably want is 'abc.*def' which searches for 'abc' followed by any number of characters, follwed by 'def'.

An application when installed on a device or on an emulator will install at:

/data/data/APP_PACKAGE_NAME

The APK itself is placed in the /data/app/ folder.

These paths, however, are in the System Partition and to access them, you will need to have root. This is for a device. On the emulator, you can see it in your logcat (DDMS) in the File Explorer tab

By the way, it only shows the package name that is defined in your Manifest.XML under the package="APP_PACKAGE_NAME" attribute. Any other packages you may have created in your project in Eclipse do not show up here.

This isn't part of numpy, but it will work with numpy.ndarray objects. A numpy.matrix can be converted to a numpy.ndarray and a numpy.ndarray can be converted to a numpy.matrix.

from sklearn.metrics import mean_squared_error
mse = mean_squared_error(A, B)

See Scikit Learn mean_squared_error for documentation on how to control axis.

Given a sample dataframe df as:

a,b
1,2
2,3
3,4
4,5

what you want is:

df['a'] = df['a'].apply(lambda x: x + 1)

that returns:

   a  b
0  2  2
1  3  3
2  4  4
3  5  5

This is, in essence, what AJAX is for. Your page loads, and you add an event to an element. When the user causes the event to be triggered, say by clicking something, your Javascript uses the XMLHttpRequest object to send a request to a server.

After the server responds (presumably with output), another Javascript function/event gives you a place to work with that output, including simply sticking it into the page like any other piece of HTML.

You can do it "by hand" with plain Javascript , or you can use jQuery. Depending on the size of your project and particular situation, it may be more simple to just use plain Javascript .

Plain Javascript

In this very basic example, we send a request to myAjax.php when the user clicks a link. The server will generate some content, in this case "hello world!". We will put into the HTML element with the id output.

The javascript

// handles the click event for link 1, sends the query
function getOutput() {
  getRequest(
      'myAjax.php', // URL for the PHP file
       drawOutput,  // handle successful request
       drawError    // handle error
  );
  return false;
}  
// handles drawing an error message
function drawError() {
    var container = document.getElementById('output');
    container.innerHTML = 'Bummer: there was an error!';
}
// handles the response, adds the html
function drawOutput(responseText) {
    var container = document.getElementById('output');
    container.innerHTML = responseText;
}
// helper function for cross-browser request object
function getRequest(url, success, error) {
    var req = false;
    try{
        // most browsers
        req = new XMLHttpRequest();
    } catch (e){
        // IE
        try{
            req = new ActiveXObject("Msxml2.XMLHTTP");
        } catch(e) {
            // try an older version
            try{
                req = new ActiveXObject("Microsoft.XMLHTTP");
            } catch(e) {
                return false;
            }
        }
    }
    if (!req) return false;
    if (typeof success != 'function') success = function () {};
    if (typeof error!= 'function') error = function () {};
    req.onreadystatechange = function(){
        if(req.readyState == 4) {
            return req.status === 200 ? 
                success(req.responseText) : error(req.status);
        }
    }
    req.open("GET", url, true);
    req.send(null);
    return req;
}

The HTML

<a href="#" onclick="return getOutput();"> test </a>
<div id="output">waiting for action</div>

The PHP

// file myAjax.php
<?php
  echo 'hello world!';
?>

With a javascript library (jQuery et al)

Arguably, that is a lot of Javascript code. You can shorten that up by tightening the blocks or using more terse logic operators, of course, but there's still a lot going on there. If you plan on doing a lot of this type of thing on your project, you might be better off with a javascript library.

Using the same HTML and PHP from above, this is your entire script (with jQuery included on the page). I've tightened up the code a little to be more consistent with jQuery's general style, but you get the idea:

// handles the click event, sends the query
function getOutput() {
   $.ajax({
      url:'myAjax.php',
      complete: function (response) {
          $('#output').html(response.responseText);
      },
      error: function () {
          $('#output').html('Bummer: there was an error!');
      }
  });
  return false;
}

Try it out: http://jsfiddle.net/GRMule/WQXXT/

Don't rush out for jQuery just yet: adding any library is still adding hundreds or thousands of lines of code to your project just as surely as if you had written them. Inside the jQuery library file, you'll find similar code to that in the first example, plus a whole lot more. That may be a good thing, it may not. Plan, and consider your project's current size and future possibility for expansion and the target environment or platform.

If this is all you need to do, write the plain javascript once and you're done.

Preflight is a web security feature implemented by the browser. For Chrome you can disable all web security by adding the --disable-web-security flag.

For example: "C:\Program Files\Google\Chrome\Application\chrome.exe" --disable-web-security --user-data-dir="C:\newChromeSettingsWithoutSecurity" . You can first create a new shortcut of chrome, go to its properties and change the target as above. This should help!

In my python interpreter exit is actually a string and not a function -- 'Use Ctrl-D (i.e. EOF) to exit.'. You can check on your interpreter by entering type(exit)

In active python what is happening is that exit is a function. If you do not call the function it will print out the string representation of the object. This is the default behaviour for any object returned. It's just that the designers thought people might try to type exit to exit the interpreter, so they made the string representation of the exit function a helpful message. You can check this behaviour by typing str(exit) or even print exit.

function getExt(filename)
{
    var ext = filename.split('.').pop();
    if(ext == filename) return "";
    return ext;
}

I would agree with @evillinux, It would be best to make your background image semi transparent so it supports < ie8

The other suggestions of using another div are also a great option, and it's the way to go if you want to do this in css. For example if the site had such features as selecting your own background color. I would suggest using a filter for older IE. eg:

filter:Alpha(opacity=50)

Use jquery change event

Description: Bind an event handler to the "change" JavaScript event, or trigger that event on an element.

An example

$("input[type='text']").change( function() {
  // your code
});

The advantage that .change has over .keypress , .focus , .blur is that .change event will fire only when input has changed

You could just divide your two numbers and multiply by 100. Note that this will throw an error if "whole" is 0, as asking what percentage of 0 a number is does not make sense:

def percentage(part, whole):
  return 100 * float(part)/float(whole)

Or with a % at the end:

 def percentage(part, whole):
  Percentage = 100 * float(part)/float(whole)
  return str(Percentage) + “%”

Or if the question you wanted it to answer was "what is 5% of 20", rather than "what percentage is 5 of 20" (a different interpretation of the question inspired by Carl Smith's answer), you would write:

def percentage(percent, whole):
  return (percent * whole) / 100.0

In case you want to use str() and a custom str method. This also works for repr.

class TypeProxy:
    def __init__(self, _type):
        self._type = _type

    def __call__(self, *args, **kwargs):
        return self._type(*args, **kwargs)

    def __str__(self):
        return self._type.__name__

    def __repr__(self):
        return "TypeProxy(%s)" % (repr(self._type),)

>>> str(TypeProxy(str))
'str'
>>> str(TypeProxy(type("")))
'str'

This gives you fixed length for the lines, but works great. The lines lengths are controlled by adding or taking '\00a0' (unicode space).

h1:before, h1:after {_x000D_
  content:'\00a0\00a0\00a0\00a0';_x000D_
  text-decoration: line-through;_x000D_
  margin: auto 0.5em;_x000D_
}

<h1>side lines</h1>

This worked best for me when I wanted to check out the code, given the commit ID <commit_id_SHA1>

git fetch origin <commit_id_SHA1>
git checkout -b new_branch FETCH_HEAD

guys i got a new way get system time. though its lengthy and is full of silly works but in this way you can get system time in integer format.

#include <stdio.h>
#include <stdlib.h>

int main()
{
    FILE *fp;
    char hc1,hc2,mc1,mc2;
    int hi1,hi2,mi1,mi2,hour,minute;
    system("echo %time% >time.txt");
    fp=fopen("time.txt","r");
    if(fp==NULL)
       exit(1) ;
    hc1=fgetc(fp);
    hc2=fgetc(fp);
    fgetc(fp);
    mc1=fgetc(fp);
    mc2=fgetc(fp);
    fclose(fp);
    remove("time.txt");
    hi1=hc1;
    hi2=hc2;
    mi1=mc1;
    mi2=mc2;
    hi1-=48;
    hi2-=48;
    mi1-=48;
    mi2-=48;
    hour=hi1*10+hi2;
    minute=mi1*10+mi2;
    printf("Current time is %d:%d\n",hour,minute);
    return 0;
}

This is almost your original proposal but almost a 1-liner. Not that complicated as other valid answers, and not so depending on bash versions (can work with old bashes).

OK=0 ; MP_FLAVOURS="vanilla lemon hazelnut straciatella"
for FLAV in $MP_FLAVOURS ; do [ $FLAV == $FLAVOR ] && { OK=1 ; break; } ; done
[ $OK -eq 0 ] && { echo "$FLAVOR not a valid value ($MP_FLAVOURS)" ; exit 1 ; }

I guess my proposal can still be improved, both in length and style.

Check out the use of the supressionCommentFilter at http://checkstyle.sourceforge.net/config_filters.html#SuppressionCommentFilter. You'll need to add the module to your checkstyle.xml

<module name="SuppressionCommentFilter"/>

and it's configurable. Thus you can add comments to your code to turn off checkstyle (at various levels) and then back on again through the use of comments in your code. E.g.

//CHECKSTYLE:OFF
public void someMethod(String arg1, String arg2, String arg3, String arg4) {
//CHECKSTYLE:ON

Or even better, use this more tweaked version:

<module name="SuppressionCommentFilter">
    <property name="offCommentFormat" value="CHECKSTYLE.OFF\: ([\w\|]+)"/>
    <property name="onCommentFormat" value="CHECKSTYLE.ON\: ([\w\|]+)"/>
    <property name="checkFormat" value="$1"/>
</module>

which allows you to turn off specific checks for specific lines of code:

//CHECKSTYLE.OFF: IllegalCatch - Much more readable than catching 7 exceptions
catch (Exception e)
//CHECKSTYLE.ON: IllegalCatch

*Note: you'll also have to add the FileContentsHolder:

<module name="FileContentsHolder"/>

See also

<module name="SuppressionFilter">
    <property name="file" value="docs/suppressions.xml"/>
</module>

under the SuppressionFilter section on that same page, which allows you to turn off individual checks for pattern matched resources.

So, if you have in your checkstyle.xml:

<module name="ParameterNumber">
   <property name="id" value="maxParameterNumber"/>
   <property name="max" value="3"/>
   <property name="tokens" value="METHOD_DEF"/>
</module>

You can turn it off in your suppression xml file with:

<suppress id="maxParameterNumber" files="YourCode.java"/>

Another method, now available in Checkstyle 5.7 is to suppress violations via the @SuppressWarnings java annotation. To do this, you will need to add two new modules (SuppressWarningsFilter and SuppressWarningsHolder) in your configuration file:

<module name="Checker">
   ...
   <module name="SuppressWarningsFilter" />
   <module name="TreeWalker">
       ...
       <module name="SuppressWarningsHolder" />
   </module>
</module> 

Then, within your code you can do the following:

@SuppressWarnings("checkstyle:methodlength")
public void someLongMethod() throws Exception {

or, for multiple suppressions:

@SuppressWarnings({"checkstyle:executablestatementcount", "checkstyle:methodlength"})
public void someLongMethod() throws Exception {

NB: The "checkstyle:" prefix is optional (but recommended). According to the docs the parameter name have to be in all lowercase, but practice indicates any case works.

You can use the HH command to open any website.

hh <http://url>

For example,

hh http://shuvankar.com

Though it will not open the website in the browser, but this will open the website in an HTML help window.

For those of you looking for python 3.4 I found a git repo with an installer that just works. Here are the direct links for x64 and x32

The substitute of fcntl on windows are win32api calls. The usage is completely different. It is not some switch you can just flip.

In other words, porting a fcntl-heavy-user module to windows is not trivial. It requires you to analyze what exactly each fcntl call does and then find the equivalent win32api code, if any.

There's also the possibility that some code using fcntl has no windows equivalent, which would require you to change the module api and maybe the structure/paradigm of the program using the module you're porting.

If you provide more details about the fcntl calls people can find windows equivalents.

Try calling it like: obj.some_function( '1', 2, '3', g="foo", h="bar" ). After the required positional arguments, you can specify specific optional arguments by name.

Yes. You'd use the urllib2 module, and encode using the multipart/form-data content type. Here is some sample code to get you started -- it's a bit more than just file uploading, but you should be able to read through it and see how it works:

                logging.info ('Ignoring non-image file %r', path)

    total_count = len (matching_filenames)
    for index, file_path in enumerate (matching_filenames):
        upload_file (file_path, index + 1, total_count)

def run_upload (options, paths):
    upload_file = make_upload_file (**options)

    for arg in paths:
        path = abspath (arg)
        if isdir (path):
            upload_directory (path, upload_file)
        elif isfile (path):
            upload_file (path)
        else:
            logging.error ('No such path: %r' % path)

    logging.info ('Done!')

Another possibility is that the result is not awaited on the client side. This can happen if any one method on the call stack does not use the await keyword to wait for the call to be completed.

If you just copy&paste the example URL that Google gives in their website http://maps.google.com/maps/api/geocode/json?address=1600+Amphitheatre+Parkway,+Mountain+View,+CA&sensor=true_or_false it will fail because of the wrong parameter of the sensor. You should change it to true or false and not the one that they wrote. Maybe is the error that you have had, like it happened to me...

JQuery:

$(function () {
      $('.SendEmail').click(function (event) {
        var email = '[email protected]';

        var attach = 'path';
        document.location = "mailto:"+email+"?subject="+subject+"&body="+emailBody+
            "?attach="+attach;
      });

If you are using Twig as a standalone component here's some example of how to enable debugging as it's unlikely the dump(variable) function will work straight out of the box

Standalone

This was found on the link provided by icode4food

$twig = new Twig_Environment($loader, array(
    'debug' => true,
    // ...
));
$twig->addExtension(new Twig_Extension_Debug());

Silex

$app->register(new \Silex\Provider\TwigServiceProvider(), array(
    'debug' => true,
    'twig.path' => __DIR__.'/views'
));

In case you need to check each of the Employee object whether it is a Manager object, use the OfType method:

List<Employee> employees = new List<Employee>();

//Code to add some Employee or Manager objects..

var onlyManagers = employees.OfType<Manager>();

foreach (Manager m in onlyManagers) {
  // Do Manager specific thing..
}

other way(unicode string even):

$res = array();
$str = 'test 1234 555 2.7 string ..... 2.2 3.3';
$str = preg_replace("/[^0-9\.]/", " ", $str);
$str = trim(preg_replace('/\s+/u', ' ', $str));
$arr = explode(' ', $str);
for ($i = 0; $i < count($arr); $i++) {
    if (is_numeric($arr[$i])) {
        $res[] = $arr[$i];
    }
}
print_r($res); //Array ( [0] => 1234 [1] => 555 [2] => 2.7 [3] => 2.2 [4] => 3.3 ) 

In a modern browser with ECMAScript 5.1 / Array.prototype.map, you can also use

jQuery._data(DOCUMENTELEMENT,'events')["EVENT_NAME"].map(function(elem){return elem.handler;});

in your browser console, which will print the source of the handlers, comma delimited. Useful for glancing at what all is running on a particular event.

Use a semicolon

OpenFileDialog of = new OpenFileDialog();
of.Filter = "Excel Files|*.xls;*.xlsx;*.xlsm";

Ruby 2.4 has Regexp#match?: (with a ?)

def integer?(str)
  /\A[+-]?\d+\z/.match? str
end

For older Ruby versions, there's Regexp#===. And although direct use of the case equality operator should generally be avoided, it looks very clean here:

def integer?(str)
  /\A[+-]?\d+\z/ === str
end

integer? "123"    # true
integer? "-123"   # true
integer? "+123"   # true

integer? "a123"   # false
integer? "123b"   # false
integer? "1\n2"   # false

See dmp's answer below. I'd delete this answer if I could, but it was accepted so this is the next best thing :)

You can't. JS Interpreters require you to compare against the switch statement (e.g. there is no "case when" statement). If you really want to do this, you can just make if(){ .. } else if(){ .. } blocks.

In the above XML, set the android:layout_weight of the linear layout as 2: android:layout_weight="2"

Another reason the breakpoints can turn yellow is if the application binary you are debugging has been modified since it was first run. In my case, I added a folder to the application's Contents/Resources folder after having debugged the program once. On the debug run after adding the folder, the breakpoints turned yellow and were ignored. I modified my procedure: I did a clean, a build, added the folder, then ran, and all was well.

Perhaps Xcode (or OS X) creates and remembers its own digital signature of the application (which was not digitally signed) and then, sensing that the application was modified, refuses to try to set breakpoints. By making my mods before the first (debug) run of the application, the digital signature was made with my mods.

All this on OS X 10.6.8 using Xcode 3.2.2.

I'd go with EXISTS over IN, see below link:

SQL Server: JOIN vs IN vs EXISTS - the logical difference

There is a common misconception that IN behaves equally to EXISTS or JOIN in terms of returned results. This is simply not true.

IN: Returns true if a specified value matches any value in a subquery or a list.

Exists: Returns true if a subquery contains any rows.

Join: Joins 2 resultsets on the joining column.

SafeAreaLayoutGuide is UIView property,

The top of the safeAreaLayoutGuide indicates the unobscured top edge of the view (e.g, not behind the status bar or navigation bar, if present). Similarly for the other edges.

Use safeAreaLayoutGuide for avoid our objects clipping/overlapping from rounded corners, navigation bars, tab bars, toolbars, and other ancestor views.

We can create safeAreaLayoutGuide object & set object constraints respectively.

Constraints for Portrait + Landscape is -

        self.edgesForExtendedLayout = []//Optional our as per your view ladder

        let newView = UIView()
        newView.backgroundColor = .red
        self.view.addSubview(newView)
        newView.translatesAutoresizingMaskIntoConstraints = false
        if #available(iOS 11.0, *) {
            let guide = self.view.safeAreaLayoutGuide
            newView.trailingAnchor.constraint(equalTo: guide.trailingAnchor).isActive = true
            newView.leadingAnchor.constraint(equalTo: guide.leadingAnchor).isActive = true
            newView.topAnchor.constraint(equalTo: guide.topAnchor).isActive = true
            newView.heightAnchor.constraint(equalToConstant: 100).isActive = true

        }
        else {
            NSLayoutConstraint(item: newView, attribute: .top, relatedBy: .equal, toItem: view, attribute: .top, multiplier: 1.0, constant: 0).isActive = true
            NSLayoutConstraint(item: newView, attribute: .leading, relatedBy: .equal, toItem: view, attribute: .leading, multiplier: 1.0, constant: 0).isActive = true
            NSLayoutConstraint(item: newView, attribute: .trailing, relatedBy: .equal, toItem: view, attribute: .trailing, multiplier: 1.0, constant: 0).isActive = true

            newView.heightAnchor.constraint(equalToConstant: 100).isActive = true
        }

$(document)[0].styleSheets[styleSheetIndex].insertRule(rule, lineIndex);

styleSheetIndex is the index value that corresponds to which order you loaded the file in the <head> (e.g. 0 is the first file, 1 is the next, etc. if there is only one CSS file, use 0).

rule is a text string CSS rule. Like this: "body { display:none; }".

lineIndex is the line number in that file. To get the last line number, use $(document)[0].styleSheets[styleSheetIndex].cssRules.length. Just console.log that styleSheet object, it's got some interesting properties/methods.

Because CSS is a "cascade", whatever rule you're trying to insert for that selector you can just append to the bottom of the CSS file and it will overwrite anything that was styled at page load.

In some browsers, after manipulating the CSS file, you have to force CSS to "redraw" by calling some pointless method in DOM JS like document.offsetHeight (it's abstracted up as a DOM property, not method, so don't use "()") -- simply adding that after your CSSOM manipulation forces the page to redraw in older browsers.

So here's an example:

var stylesheet = $(document)[0].styleSheets[0]; stylesheet.insertRule('body { display:none; }', stylesheet.cssRules.length);

Yes.

new ArrayList<String>(){{
   add("A");
   add("B");
}}

What this is actually doing is creating a class derived from ArrayList<String> (the outer set of braces do this) and then declare a static initialiser (the inner set of braces). This is actually an inner class of the containing class, and so it'll have an implicit this pointer. Not a problem unless you want to serialise it, or you're expecting the outer class to be garbage collected.

I understand that Java 7 will provide additional language constructs to do precisely what you want.

EDIT: recent Java versions provide more usable functions for creating such collections, and are worth investigating over the above (provided at a time prior to these versions)

Detect the operating system using two simple tricks:

• First the environment variable OS
• Then the uname command

ifeq ($(OS),Windows_NT)     # is Windows_NT on XP, 2000, 7, Vista, 10...
    detected_OS := Windows
else
    detected_OS := $(shell uname)  # same as "uname -s"
endif

Or a more safe way, if not on Windows and uname unavailable:

ifeq ($(OS),Windows_NT) 
    detected_OS := Windows
else
    detected_OS := $(shell sh -c 'uname 2>/dev/null || echo Unknown')
endif

Ken Jackson proposes an interesting alternative if you want to distinguish Cygwin/MinGW/MSYS/Windows. See his answer that looks like that:

ifeq '$(findstring ;,$(PATH))' ';'
    detected_OS := Windows
else
    detected_OS := $(shell uname 2>/dev/null || echo Unknown)
    detected_OS := $(patsubst CYGWIN%,Cygwin,$(detected_OS))
    detected_OS := $(patsubst MSYS%,MSYS,$(detected_OS))
    detected_OS := $(patsubst MINGW%,MSYS,$(detected_OS))
endif

Then you can select the relevant stuff depending on detected_OS:

ifeq ($(detected_OS),Windows)
    CFLAGS += -D WIN32
endif
ifeq ($(detected_OS),Darwin)        # Mac OS X
    CFLAGS += -D OSX
endif
ifeq ($(detected_OS),Linux)
    CFLAGS   +=   -D LINUX
endif
ifeq ($(detected_OS),GNU)           # Debian GNU Hurd
    CFLAGS   +=   -D GNU_HURD
endif
ifeq ($(detected_OS),GNU/kFreeBSD)  # Debian kFreeBSD
    CFLAGS   +=   -D GNU_kFreeBSD
endif
ifeq ($(detected_OS),FreeBSD)
    CFLAGS   +=   -D FreeBSD
endif
ifeq ($(detected_OS),NetBSD)
    CFLAGS   +=   -D NetBSD
endif
ifeq ($(detected_OS),DragonFly)
    CFLAGS   +=   -D DragonFly
endif
ifeq ($(detected_OS),Haiku)
    CFLAGS   +=   -D Haiku
endif

Notes:

• Command uname is same as uname -s because option -s (--kernel-name) is the default. See why uname -s is better than uname -o.

• The use of OS (instead of uname) simplifies the identification algorithm. You can still use solely uname, but you have to deal with if/else blocks to check all MinGW, Cygwin, etc. variations.

• The environment variable OS is always set to "Windows_NT" on different Windows versions (see %OS% environment variable on Wikipedia).

• An alternative of OS is the environment variable MSVC (it checks the presence of MS Visual Studio, see example using Visual C++).

Below I provide a complete example using make and gcc to build a shared library: *.so or *.dll depending on the platform. The example is as simplest as possible to be more understandable.

To install make and gcc on Windows see Cygwin or MinGW.

My example is based on five files

 +-- lib
 ¦   +-- Makefile
 ¦   +-- hello.h
 ¦   +-- hello.c
 +-- app
     +-- Makefile
     +-- main.c

Reminder: Makefile is indented using tabulation. Caution when copy-pasting below sample files.

The two Makefile files

1. lib/Makefile

ifeq ($(OS),Windows_NT)
    uname_S := Windows
else
    uname_S := $(shell uname -s)
endif

ifeq ($(uname_S), Windows)
    target = hello.dll
endif
ifeq ($(uname_S), Linux)
    target = libhello.so
endif
#ifeq ($(uname_S), .....) #See https://stackoverflow.com/a/27776822/938111
#    target = .....
#endif

%.o: %.c
    gcc  -c $<  -fPIC  -o $@
    # -c $<  => $< is first file after ':' => Compile hello.c
    # -fPIC  => Position-Independent Code (required for shared lib)
    # -o $@  => $@ is the target => Output file (-o) is hello.o

$(target): hello.o
    gcc  $^  -shared  -o $@
    # $^      => $^ expand to all prerequisites (after ':') => hello.o
    # -shared => Generate shared library
    # -o $@   => Output file (-o) is $@ (libhello.so or hello.dll)

2. app/Makefile

ifeq ($(OS),Windows_NT)
    uname_S := Windows
else
    uname_S := $(shell uname -s)
endif

ifeq ($(uname_S), Windows)
    target = app.exe
endif
ifeq ($(uname_S), Linux)
    target = app
endif
#ifeq ($(uname_S), .....) #See https://stackoverflow.com/a/27776822/938111
#    target = .....
#endif

%.o: %.c
    gcc  -c $< -I ../lib  -o $@
    # -c $<     => compile (-c) $< (first file after :) = main.c
    # -I ../lib => search headers (*.h) in directory ../lib
    # -o $@     => output file (-o) is $@ (target) = main.o

$(target): main.o
    gcc  $^  -L../lib  -lhello  -o $@
    # $^       => $^ (all files after the :) = main.o (here only one file)
    # -L../lib => look for libraries in directory ../lib
    # -lhello  => use shared library hello (libhello.so or hello.dll)
    # -o $@    => output file (-o) is $@ (target) = "app.exe" or "app"

To learn more, read Automatic Variables documentation as pointed out by cfi.

The source code

- lib/hello.h

#ifndef HELLO_H_
#define HELLO_H_

const char* hello();

#endif

- lib/hello.c

#include "hello.h"

const char* hello()
{
    return "hello";
}

- app/main.c

#include "hello.h" //hello()
#include <stdio.h> //puts()

int main()
{
    const char* str = hello();
    puts(str);
}

The build

Fix the copy-paste of Makefile (replace leading spaces by one tabulation).

> sed  's/^  */\t/'  -i  */Makefile

The make command is the same on both platforms. The given output is on Unix-like OSes:

> make -C lib
make: Entering directory '/tmp/lib'
gcc  -c hello.c  -fPIC  -o hello.o
# -c hello.c  => hello.c is first file after ':' => Compile hello.c
# -fPIC       => Position-Independent Code (required for shared lib)
# -o hello.o  => hello.o is the target => Output file (-o) is hello.o
gcc  hello.o  -shared  -o libhello.so
# hello.o        => hello.o is the first after ':' => Link hello.o
# -shared        => Generate shared library
# -o libhello.so => Output file (-o) is libhello.so (libhello.so or hello.dll)
make: Leaving directory '/tmp/lib'

> make -C app
make: Entering directory '/tmp/app'
gcc  -c main.c -I ../lib  -o main.o
# -c main.c => compile (-c) main.c (first file after :) = main.cpp
# -I ../lib => search headers (*.h) in directory ../lib
# -o main.o => output file (-o) is main.o (target) = main.o
gcc  main.o  -L../lib  -lhello  -o app
# main.o   => main.o (all files after the :) = main.o (here only one file)
# -L../lib => look for libraries in directory ../lib
# -lhello  => use shared library hello (libhello.so or hello.dll)
# -o app   => output file (-o) is app.exe (target) = "app.exe" or "app"
make: Leaving directory '/tmp/app'

The run

The application requires to know where is the shared library.

On Windows, a simple solution is to copy the library where the application is:

> cp -v lib/hello.dll app
`lib/hello.dll' -> `app/hello.dll'

On Unix-like OSes, you can use the LD_LIBRARY_PATH environment variable:

> export LD_LIBRARY_PATH=lib

Run the command on Windows:

> app/app.exe
hello

Run the command on Unix-like OSes:

> app/app
hello

You can try group by on name and count the ids in that group.

SELECT name, count(id) as COUNT FROM table group by name

Oracle's free SQL Developer will do this:

http://www.oracle.com/technetwork/developer-tools/sql-developer/overview/index.html

You just find your table, right-click on it and choose Export Data->Insert

This will give you a file with your insert statements. You can also export the data in SQL Loader format as well.

Looks like this is on the bottom left now as an icon with overlapping windows and the "Undock into separate window." tooltip.

In MSSQL, this could be the way:

select distinct city from station 
where
right(city,1) in ('a', 'e', 'i', 'o','u') and left(city,1) in ('a', 'e', 'i', 'o','u') 

The ByteBuffer class is important because it forms a basis for the use of channels in Java. ByteBuffer class defines six categories of operations upon byte buffers, as stated in the Java 7 documentation:

• Absolute and relative get and put methods that read and write single bytes;

• Relative bulk get methods that transfer contiguous sequences of bytes from this buffer into an array;

• Relative bulk put methods that transfer contiguous sequences of bytes from a byte array or some other byte buffer into this buffer;

• Absolute and relative get and put methods that read and write values of other primitive types, translating them to and from sequences of bytes in a particular byte order;

• Methods for creating view buffers, which allow a byte buffer to be viewed as a buffer containing values of some other primitive type; and

• Methods for compacting, duplicating, and slicing a byte buffer.

Example code : Putting Bytes into a buffer.

    // Create an empty ByteBuffer with a 10 byte capacity
    ByteBuffer bbuf = ByteBuffer.allocate(10);

    // Get the buffer's capacity
    int capacity = bbuf.capacity(); // 10

    // Use the absolute put(int, byte).
    // This method does not affect the position.
    bbuf.put(0, (byte)0xFF); // position=0

    // Set the position
    bbuf.position(5);

    // Use the relative put(byte)
    bbuf.put((byte)0xFF);

    // Get the new position
    int pos = bbuf.position(); // 6

    // Get remaining byte count
    int rem = bbuf.remaining(); // 4

    // Set the limit
    bbuf.limit(7); // remaining=1

    // This convenience method sets the position to 0
    bbuf.rewind(); // remaining=7

The Predicate will always return a boolean, by definition.

Predicate<T> is basically identical to Func<T,bool>.

Predicates are very useful in programming. They are often used to allow you to provide logic at runtime, that can be as simple or as complicated as necessary.

For example, WPF uses a Predicate<T> as input for Filtering of a ListView's ICollectionView. This lets you write logic that can return a boolean determining whether a specific element should be included in the final view. The logic can be very simple (just return a boolean on the object) or very complex, all up to you.

The documentation has been updated. My answer has substantial changes vs the accepted answer: I wanted to reflect documentation is up-to-date, and accepted answer has a few broken links.

Also, I didn't understand when the accepted answer said "it defaults to node server.js". I think the documentation clarifies the default behavior:

npm-start

Start a package

Synopsis

npm start [-- <args>]

Description

This runs an arbitrary command specified in the package's "start" property of its "scripts" object. If no "start" property is specified on the "scripts" object, it will run node server.js.

In summary, running npm start could do one of two things:

1. npm start {command_name}: Run an arbitrary command (i.e. if such command is specified in the start property of package.json's scripts object)
2. npm start: Else if no start property exists (or no command_name is passed): Run node server.js, (which may not be appropriate, for example the OP doesn't have server.js; the OP runs nodeapp.js )
3. I said I would list only 2 items, but are other possibilities (i.e. error cases). For example, if there is no package.json in the directory where you run npm start, you may see an error: npm ERR! enoent ENOENT: no such file or directory, open '.\package.json'

This is known as the "fragment identifier" and is typically used to identify a portion of an HTML document that sits within a fully qualified URL:

The best option is probably to have a still image which you replace the gif with when you want to stop it.

<img src="gif/1303552574110.1.gif" alt="" class="anim" >
<img src="gif/1302919192204.gif" alt="" class="anim" >
<img src="gif/1303642234740.gif" alt="" class="anim" >
<img src="gif/1303822879528.gif" alt="" class="anim" >
<img src="gif/1303825584512.gif" alt="" class="anim" >

$(window).load(function() {
  $(".anim").src("stillimage.gif");
});

$(".anim").mouseover(function {
  $(this).src("animatedimage.gif");
});

$(".anim").mouseout(function {
  $(this).src("stillimage.gif");
});

You probably want to have two arrays containing paths to the still and animated gifs which you can assign to each image.

Browsers other than IE treat the conditional statements as comments because they're enclosed inside comment tags.

<!--[if IE]>
Non-IE browsers ignore this
<![endif]-->

However, when you're targeting a browser that is NOT IE you have to use 2 comments, one before and one after the code. IE will ignore the code between them, whereas other browsers will treat it as normal code. The syntax for targeting non-IE browsers is therefore:

<!--[if !IE]-->
IE ignores this
<!--[endif]-->

Note: These conditional comments are no longer supported from IE 10 onwards.

if you need double quoted JSON use JSON.stringify( object)

var $items = $('#firstName, #lastName,#phoneNumber,#address ')
var obj = {}
$items.each(function() {
    obj[this.id] = $(this).val();
})

var json= JSON.stringify( obj);

DEMO: http://jsfiddle.net/vANKa/1

this worked:

    Date date = null;
    String dateStr = rs.getString("doc_date");
    if (dateStr != null) {
        date = dateFormat.parse(dateStr);
    }

using SimpleDateFormat.

If you are connected to Wi-Fi network, then it is much simpler. Just find the Ip in which you have connected to the Wi-Fi. Eg:

your-ip is "10.10.55.67".

Then start the xampp server in your machine.

Then in anyother computer connected to the same Wi-Fi n/w, type

http://your-ip

Eg:http://10.10.55.67

1. Go to Toolbar -> Settings -> Compiler
2. In the Selected compiler drop-down menu, make sure GNU GCC Compiler is selected
3. Below that, select the compiler settings tab and then the compiler flags tab underneath
4. In the list below, make sure the box for "Have g++ follow the C++11 ISO C++ language standard [-std=c++11]" is checked
5. Click OK to save

Ok, if it doesn't matter which value in the non-duplicated column you select, this should be pretty easy:

dat <- data.frame(id=c(1,1,3),id2=c(1,1,4),somevalue=c("x","y","z"))
> dat[!duplicated(dat[,c('id','id2')]),]
  id id2 somevalue
1  1   1         x
3  3   4         z

Inside the duplicated call, I'm simply passing only those columns from dat that I don't want duplicates of. This code will automatically always select the first of any ambiguous values. (In this case, x.)

Try disabling firewall.

This might be a very weird solution but I had the same problem and I'm running Android 2.3 on windows 32 bit . I deleted the current app and disabled firewall. Upon creating a new project everything worked fine.

Try to call randomize() before rand() to initialize random generator.

(look at: srand() — why call it only once?)

The default constructor initializes the string to the empty string. This is the more economic way of saying the same thing.

However, the comparison to NULL stinks. That is an older syntax still in common use that means something else; a null pointer. It means that there is no string around.

If you want to check whether a string (that does exist) is empty, use the empty method instead:

if (myStr.empty()) ...

System.String is a reference type and already "nullable".

Nullable<T> and the ? suffix are for value types such as Int32, Double, DateTime, etc.

I was struggling a lot with different solutions including \vspace{-Xmm} on the top and bottom of the page and dealing with warnings and errors. Finally I found this answer:

You can change the margins of just one or more pages and then restore it to its default:

\usepackage{geometry}
...
... 
...
\newgeometry{top=5mm, bottom=10mm}     % use whatever margins you want for left, right, top and bottom.
...
... %<The contents of enlarged page(s)>
...    
\restoregeometry     %so it does not affect the rest of the pages.
...
... 
...

PS:

1- This can also fix the following warning:

LaTeX Warning: Float too large for page by ...pt on input line ...

2- For more detailed answer look at this.

3- I just found that this is more elaboration on Kevin Chen's answer.

Try this so you don't need to worry about where your logs are:

dmesg -T | egrep -i 'killed process'

-T - readable timestamps

If you would like it to go back to first option try this:

   document.getElementById("select").selectedIndex = 0;

You can first concatenate the strings in the list with the separator ';' using the function join and then use the split function in order create the list:

l = ['Facebook;Google+;MySpace', 'Apple;Android']

l1 = ";".join(l)).split(";")  

print l1

outputs

['Facebook', 'Google+', 'MySpace', 'Apple', 'Android']

Small And Better One

var i = 0;
$("#container > option").each(function(){ 
    if($(this).val().length > i) {
        i = $(this).val().length;

        console.log(i);
        console.log($(this).val());
    }
});

Use listboxControl.Column(intColumn,intRow). Both Column and Row are zero-based.

Note in Python 2.6+ and Py3K, the %f character catches microseconds.

>>> datetime.datetime.strptime("2008-09-03T20:56:35.450686Z", "%Y-%m-%dT%H:%M:%S.%fZ")

See issue here

var str = "Hello, this is Mike (example)";

alert(str.replace(/\s*\(.*?\)\s*/g, ''));

That'll also replace excess whitespace before and after the parentheses.

You could also consider:

RUN apt-get update && apt-get install -y iputils-ping

(as Contango comments: you must first run apt-get update, to avoid error with missing repository).

See "Replacing ifconfig with ip"

it is most often recommended to move forward with the command that has replaced ifconfig. That command is ip, and it does a great job of stepping in for the out-of-date ifconfig.

But as seen in "Getting a Docker container's IP address from the host", using docker inspect can be more useful depending on your use case.

In Opera, try:

    print_win.document.write('</body></html>');
    print_win.document.close(); // This bit is important
    print_win.print();
    print_win.close();

If you want a GUI to access SVN repos you can use http://tortoisesvn.tigris.org/ (and its Repobrwoser) If you want a browser based tool, to browse ANY SVN repo without installing SVn on your machine, i don't such a tool. I know only tools to install to your webserver and needed a installed SVN client on these server. To checkout or export a svn repo you need a svn client. (or you copy the files from the command line =) )

If you just want to filter null values out of a stream, you can simply use a method reference to java.util.Objects.nonNull(Object). From its documentation:

This method exists to be used as a Predicate, filter(Objects::nonNull)

For example:

List<String> list = Arrays.asList( null, "Foo", null, "Bar", null, null);

list.stream()
    .filter( Objects::nonNull )  // <-- Filter out null values
    .forEach( System.out::println );

This will print:

Foo
Bar

Use kebab-case for all package, folder and file names.

Why?

You should imagine that any folder or file might be extracted to its own package some day. Packages cannot contain uppercase letters.

New packages must not have uppercase letters in the name. https://docs.npmjs.com/files/package.json#name

Therefore, camelCase should never be used. This leaves snake_case and kebab-case.

kebab-case is by far the most common convention today. The only use of underscores is for internal node packages, and this is simply a convention from the early days.

Alternatives:

>>> map(a.__getitem__, b)
[1, 5, 5]

>>> import operator
>>> operator.itemgetter(*b)(a)
(1, 5, 5)

HTML:

<div class="foo">
    /* whatever is required */
</div>

CSS:

.foo {
    top: 0;
    transition: top ease 0.5s;
}

.foo:hover{
    top: -10px;
}

This is just a basic transition to ease the div tag up by 10px when it is hovered on. The transition property's values can be edited along with the class.hover properties to determine how the transition works.

I wanted to note that the fourth part of Accepted Answer is wrong .

theApp.factory('mainInfo', function($http) { 

var obj = {content:null};

$http.get('content.json').success(function(data) {
    // you can do some processing here
    obj.content = data;
});    

return obj;    
});

The above code as @Karl Zilles wrote will fail because obj will always be returned before it receives data (thus the value will always be null) and this is because we are making an Asynchronous call.

The details of similar questions are discussed in this post

In Angular, use $promise to deal with the fetched data when you want to make an asynchronous call.

The simplest version is

theApp.factory('mainInfo', function($http) { 
    return {
        get:  function(){
            $http.get('content.json'); // this will return a promise to controller
        }
});


// and in controller

mainInfo.get().then(function(response) { 
    $scope.foo = response.data.contentItem;
});

The reason I don't use success and error is I just found out from the doc, these two methods are deprecated.

The $http legacy promise methods success and error have been deprecated. Use the standard then method instead.

You can try the following: (This may be duplicate of the answers posted but I have added description)

Display all users that can be seen by the current user:

SELECT * FROM all_users;

Display all users in the Database:

SELECT * FROM dba_users;

Display the information of the current user:

SELECT * FROM user_users;

Lastly, this will display all users that can be seen by current users based on creation date:

SELECT * FROM all_users
ORDER BY created;

You could use conditional compilation:

#ifdef WINDOWS
#include <Windows.h>
void beep() {
  Beep(440, 1000);
}
#elif LINUX
#include <stdio.h>
void beep() {
  system("echo -e "\007" >/dev/tty10");
}
#else
#include <stdio.h>
void beep() {
  cout << "\a" << flush;
}
#endif

I would use the reverse() function from the <algorithm> library.

Run it online: repl.it/@abranhe/Reverse-Array

#include <iostream>
#include <algorithm>
using namespace std;

int main()
{
  int arr [10] = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10};

  reverse(begin(arr), end(arr));

  for(auto item:arr)
  {
    cout << item << " ";
  }
}

Output:

10 9 8 7 6 5 4 3 2 1

Hope you like this approach.

How about alias gcc99= gcc -std=c99?

To run function onLoad

jQuery(window).on("load", function(){
    ..code..
});

To run code onDOMContentLoaded (also called onready)

jQuery(document).ready(function(){
    ..code..
});

or the recommended shorthand for onready

jQuery(function($){
    ..code.. ($ is the jQuery object)
});

onready fires when the document has loaded

onload fires when the document and all the associated content, like the images on the page have loaded.

Use the below Power shell command to change the execution timeout (Request Timeout)

Please note that I have given this for default web site, before using these please change the site and then try to use this.

 Set-WebConfigurationProperty -pspath 'MACHINE/WEBROOT/APPHOST/Default Web Site'  -filter "system.web/httpRuntime" -name "executionTimeout" -value "00:01:40"

Or, You can use the below C# code to do the same thing

using System;
using System.Text;
using Microsoft.Web.Administration;

internal static class Sample {

    private static void Main() {

        using(ServerManager serverManager = new ServerManager()) { 
            Configuration config = serverManager.GetWebConfiguration("Default Web Site");

            ConfigurationSection httpRuntimeSection = config.GetSection("system.web/httpRuntime");
            httpRuntimeSection["executionTimeout"] = TimeSpan.Parse("00:01:40");

            serverManager.CommitChanges();
        }
    }
}

Or, you can use the JavaScript to do this.

var adminManager = new ActiveXObject('Microsoft.ApplicationHost.WritableAdminManager');
adminManager.CommitPath = "MACHINE/WEBROOT/APPHOST/Default Web Site";

var httpRuntimeSection = adminManager.GetAdminSection("system.web/httpRuntime", "MACHINE/WEBROOT/APPHOST/Default Web Site");
httpRuntimeSection.Properties.Item("executionTimeout").Value = "00:01:40";

adminManager.CommitChanges();

Or, you can use the AppCmd commands.

appcmd.exe set config "Default Web Site" -section:system.web/httpRuntime /executionTimeout:"00:01:40" 

Reproducing tim_yates answer on current hardware and adding leftShift() and concat() method to check the finding:

  'String leftShift' {
    foo << bar << baz
  }
  'String concat' {
    foo.concat(bar)
       .concat(baz)
       .toString()
  }

The outcome shows concat() to be the faster solution for a pure String, but if you can handle GString somewhere else, GString template is still ahead, while honorable mention should go to leftShift() (bitwise operator) and StringBuffer() with initial allocation:

On Windows, Ctrl+Shift+r would force reload the script in chrome.

XSLT 1.0 does not have an integer data type, only double. You can use number() to convert a string to a number.

return is part of a function definition, while print outputs text to the standard output (usually the console).

A function is a procedure accepting parameters and returning a value. return is for the latter, while the former is done with def.

Example:

def timestwo(x):
    return x*2

You can use OnClientClick event to call a JavaScript function:

<asp:Button ID="Button1" runat="server" Text="Button" onclientclick='redirect()' />

JavaScript code:

function redirect() {
  location.href = 'page.aspx';
}

But i think the best would be to style a hyperlink with css.

Example :

.button {
  display: block;
  height: 25px;
  background: #f1f1f1;
  padding: 10px;
  text-align: center;
  border-radius: 5px;
  border: 1px solid #e1e1e2;
  color: #000;
  font-weight: bold;
}

You don't have to give up simple css :)

.short { max-width: 300px; }
<input type="text" class="form-control short" id="...">

Using standard java libs, I suggest looking at the HttpUrlConnection class http://java.sun.com/javase/6/docs/api/java/net/HttpURLConnection.html

It can handle most of what curl can do with setting up the connection. What you do with the stream is up to you.

I had the same problem with a freshly installed copy of Chrome. If nothing works, and your Use a proxy server your LAN setting is unchecked, check it and then uncheck it . Believe it or not it might work. I don't know if I should consider it a bug or not.

When using the apache poi 4.1.2. The celltype changes a bit. Below is an example

    try {
        File excel = new File("/home/name/Downloads/bb.xlsx");
        FileInputStream fis = new FileInputStream(excel);
        XSSFWorkbook book = new XSSFWorkbook(fis);
        XSSFSheet sheet = book.getSheetAt(0);

        Iterator<Row> itr = sheet.iterator();

        // Iterating over Excel file in Java
        while (itr.hasNext()) {
            Row row = itr.next();

            Iterator<Cell> cellIterator = row.cellIterator();
            while (cellIterator.hasNext()) {



                Cell cell = cellIterator.next();



                switch (cell.getCellType()) {
                case STRING:
                    System.out.print(cell.getStringCellValue() + "\t");
                    break;
                case NUMERIC:
                    System.out.print(cell.getNumericCellValue() + "\t");
                    break;
                case BOOLEAN:
                    System.out.print(cell.getBooleanCellValue() + "\t");
                    break;
                default:


                }
            }
            System.out.println("");}
        }catch (Exception e) {
            // TODO: handle exception
            e.printStackTrace();
        }

It is possible to use a handler to do this, even in MVC4. Here's an example from one i made earlier:

public class ImageHandler : IHttpHandler
{
    byte[] bytes;

    public void ProcessRequest(HttpContext context)
    {
        int param;
        if (int.TryParse(context.Request.QueryString["id"], out param))
        {
            using (var db = new MusicLibContext())
            {
                if (param == -1)
                {
                    bytes = File.ReadAllBytes(HttpContext.Current.Server.MapPath("~/Images/add.png"));

                    context.Response.ContentType = "image/png";
                }
                else
                {
                    var data = (from x in db.Images
                                where x.ImageID == (short)param
                                select x).FirstOrDefault();

                    bytes = data.ImageData;

                    context.Response.ContentType = "image/" + data.ImageFileType;
                }

                context.Response.Cache.SetCacheability(HttpCacheability.NoCache);
                context.Response.BinaryWrite(bytes);
                context.Response.Flush();
                context.Response.End();
            }
        }
        else
        {
            //image not found
        }
    }

    public bool IsReusable
    {
        get
        {
            return false;
        }
    }
}

In the view, i added the ID of the photo to the query string of the handler.

String rawData = "id=10";
String type = "application/x-www-form-urlencoded";
String encodedData = URLEncoder.encode( rawData, "UTF-8" ); 
URL u = new URL("http://www.example.com/page.php");
HttpURLConnection conn = (HttpURLConnection) u.openConnection();
conn.setDoOutput(true);
conn.setRequestMethod("POST");
conn.setRequestProperty( "Content-Type", type );
conn.setRequestProperty( "Content-Length", String.valueOf(encodedData.length()));
OutputStream os = conn.getOutputStream();
os.write(encodedData.getBytes());

This is a quite old question, still comments show, that still people have problems, so here is my solution with following additional features:

• adjust the animation (speed, type, ...)
• does not need to extend any class
• in my case, animateLayoutChanges has problems in the new CoordinatorLayout

Function - Example (I have this function in an utility class)

public static void animateViewVisibility(final View view, final int visibility)
{
    // cancel runnning animations and remove and listeners
    view.animate().cancel();
    view.animate().setListener(null);

    // animate making view visible
    if (visibility == View.VISIBLE)
    {
        view.animate().alpha(1f).start();
        view.setVisibility(View.VISIBLE);
    }
    // animate making view hidden (HIDDEN or INVISIBLE)
    else
    {
        view.animate().setListener(new AnimatorListenerAdapter()
        {
            @Override
            public void onAnimationEnd(Animator animation)
            {
                view.setVisibility(visibility);
            }
        }).alpha(0f).start();
    }
}

Adjust animation

After calling view.animate() you can adjust the animation to whatever you want (set duration, set interpolator and more...). You may as well hide a view by scaling it instead of adjusting it's alpha value, just replace the alpha(...) with scaleX(...) or scaleY(...) in the utility method if you want that

The fix is really simple: just replace YOUR_API_KEY on the last line of your code with your actual API key!

If you don't have one, you can get it for free on the Google Developers Website.

I do the following, if you want to use it then paste it in some where and set your handler code in locationHashChanged(qs) where commented, and then call changeHashValue(hashQuery) every time you load an ajax request. Its not a quick-fix answer and there are none, so you will need to think about it and pass sensible hashQuery args (ie a=1&b=2) to changeHashValue(hashQuery) and then cater for each combination of said args in your locationHashChanged(qs) callback ...

// Add code below ...
function locationHashChanged(qs)
{
  var q = parseQs(qs);
  // ADD SOME CODE HERE TO LOAD YOUR PAGE ELEMS AS PER q !!
  // YOU SHOULD CATER FOR EACH hashQuery ATTRS COMBINATION
  //  THAT IS PASSED TO changeHashValue(hashQuery)
}

// CALL THIS FROM YOUR AJAX LOAD CODE EACH LOAD ...
function changeHashValue(hashQuery)
{
  stopHashListener();
  hashValue     = hashQuery;
  location.hash = hashQuery;
  startHashListener();
}

// AND DONT WORRY ABOUT ANYTHING BELOW ...
function checkIfHashChanged()
{
  var hashQuery = getHashQuery();
  if (hashQuery == hashValue)
    return;
  hashValue = hashQuery;
  locationHashChanged(hashQuery);
}

function parseQs(qs)
{
  var q = {};
  var pairs = qs.split('&');
  for (var idx in pairs) {
    var arg = pairs[idx].split('=');
    q[arg[0]] = arg[1];
  }
  return q;
}

function startHashListener()
{
  hashListener = setInterval(checkIfHashChanged, 1000);
}

function stopHashListener()
{
  if (hashListener != null)
    clearInterval(hashListener);
  hashListener = null;
}

function getHashQuery()
{
  return location.hash.replace(/^#/, '');
}

var hashListener = null;
var hashValue    = '';//getHashQuery();
startHashListener();

Use timer.scheduleAtFixedRate

public void scheduleAtFixedRate(TimerTask task,
                                long delay,
                                long period)

Schedules the specified task for repeated fixed-rate execution, beginning after the specified delay. Subsequent executions take place at approximately regular intervals, separated by the specified period.
In fixed-rate execution, each execution is scheduled relative to the scheduled execution time of the initial execution. If an execution is delayed for any reason (such as garbage collection or other background activity), two or more executions will occur in rapid succession to "catch up." In the long run, the frequency of execution will be exactly the reciprocal of the specified period (assuming the system clock underlying Object.wait(long) is accurate).

Fixed-rate execution is appropriate for recurring activities that are sensitive to absolute time, such as ringing a chime every hour on the hour, or running scheduled maintenance every day at a particular time. It is also appropriate for recurring activities where the total time to perform a fixed number of executions is important, such as a countdown timer that ticks once every second for ten seconds. Finally, fixed-rate execution is appropriate for scheduling multiple repeating timer tasks that must remain synchronized with respect to one another.

Parameters:

• task - task to be scheduled.
• delay - delay in milliseconds before task is to be executed.
• period - time in milliseconds between successive task executions.

Throws:

• IllegalArgumentException - if delay is negative, or delay + System.currentTimeMillis() is negative.
• IllegalStateException - if task was already scheduled or cancelled, timer was cancelled, or timer thread terminated.

I'm not sure you have gotten past this yet, but I had to work on something very similar today and I got your fiddle working like you are asking, basically what I did was make another table row under it, and then used the accordion control. I tried using just collapse but could not get it working and saw an example somewhere on SO that used accordion.

Here's your updated fiddle: http://jsfiddle.net/whytheday/2Dj7Y/11/

Since I need to post code here is what each collapsible "section" should look like ->

<tr data-toggle="collapse" data-target="#demo1" class="accordion-toggle">
    <td>1</td>
    <td>05 May 2013</td>
    <td>Credit Account</td>
    <td class="text-success">$150.00</td>
    <td class="text-error"></td>
    <td class="text-success">$150.00</td>
</tr>

<tr>
    <td colspan="6" class="hiddenRow">
        <div class="accordion-body collapse" id="demo1">Demo1</div>
    </td>
</tr>

According to spark documentation "where() is an alias for filter()"

filter(condition) Filters rows using the given condition. where() is an alias for filter().

Parameters: condition – a Column of types.BooleanType or a string of SQL expression.

>>> df.filter(df.age > 3).collect()
[Row(age=5, name=u'Bob')]
>>> df.where(df.age == 2).collect()
[Row(age=2, name=u'Alice')]

>>> df.filter("age > 3").collect()
[Row(age=5, name=u'Bob')]
>>> df.where("age = 2").collect()
[Row(age=2, name=u'Alice')]

So many great answers but since I've just written a function (plotMultipleHistograms() in 'basicPlotteR' package) function to do this, I thought I would add another answer.

The advantage of this function is that it automatically sets appropriate X and Y axis limits and defines a common set of bins that it uses across all the distributions.

Here's how to use it:

# Install the plotteR package
install.packages("devtools")
devtools::install_github("JosephCrispell/basicPlotteR")
library(basicPlotteR)

# Set the seed
set.seed(254534)

# Create random samples from a normal distribution
distributions <- list(rnorm(500, mean=5, sd=0.5), 
                      rnorm(500, mean=8, sd=5), 
                      rnorm(500, mean=20, sd=2))

# Plot overlapping histograms
plotMultipleHistograms(distributions, nBins=20, 
                       colours=c(rgb(1,0,0, 0.5), rgb(0,0,1, 0.5), rgb(0,1,0, 0.5)), 
                       las=1, main="Samples from normal distribution", xlab="Value")

The plotMultipleHistograms() function can take any number of distributions, and all the general plotting parameters should work with it (for example: las, main, etc.).

...
WHERE ...
      AND (@Location is null OR (Location like '%' + @Location + '%'))
      AND (@Date is null OR (Date = @Date))

This way it is more obvious the parameter is not used when null.

function removeHash () { 
    history.pushState("", document.title, window.location.pathname
                                          + window.location.search);
}


App.$router.replace({name:"my-route", hash: '#update'})
App.$router.replace({name:"my-route", hash: ' ', params: {a: 100} })
setTimeout(removeHash, 0)

Notes:

1. And the # must have some value after it.
2. The second route hash is a space, not empty string.
3. setTimeout, not $nextTick to keep the url clean.

Easy solution - copy from excel and paste into google sheets. It copies all of your reference cells as absolute cells so you can begin from scratch. Then sort and download back as an excel grid and reformat to your needs.

Adrian's answer threw "fatal: This operation must be run in a work tree." The following is what worked for us.

git worktree add <new-dir> --no-checkout --detach
cd <new-dir>
git checkout <some-ref> -- <existing-dir>

Notes:

• --no-checkout Do not checkout anything into the new worktree.
• --detach Do not create a new branch for the new worktree.
• <some-ref> works with any ref, for instance, it works with HEAD~1.
• Cleanup with git worktree prune.

As mentioned before, you cannot create free certificates for S3 buckets. However, you can create Cloud Front distribution and then assign the certificate for the Cloud Front instead. You request the certificate for your domain and then just assign it to the Cloud Front distribution in the Cloud Front settings. I've used this method to serve static websites via SSL as well as serve static files.

For static website creation Amazon is the go to place. It is really affordable to get a static website with SSL.

function setMarkers(map,locations){

for (var i = 0; i < locations.length; i++)
 {  

 var loan = locations[i][0];
 var lat = locations[i][1];
 var long = locations[i][2];
 var add =  locations[i][3];

 latlngset = new google.maps.LatLng(lat, long);

 var marker = new google.maps.Marker({  
          map: map, title: loan , position: latlngset  
 });
 map.setCenter(marker.getPosition());


 marker.content = "<h3>Loan Number: " + loan +  '</h3>' + "Address: " + add;


 google.maps.events.addListener(marker,'click', function(map,marker){
          map.infowindow.setContent(marker.content);
          map.infowindow.open(map,marker);

 });

 }
}

Then move var infowindow = new google.maps.InfoWindow() to the initialize() function:

function initialize() {

    var myOptions = {
      center: new google.maps.LatLng(33.890542, 151.274856),
      zoom: 8,
      mapTypeId: google.maps.MapTypeId.ROADMAP

    };
    var map = new google.maps.Map(document.getElementById("default"),
        myOptions);
    map.infowindow = new google.maps.InfoWindow();

    setMarkers(map,locations)

  }

1. What exactly doesn't work?
2. Why are you using a 2d array?

3. If you must use a 2d array:

   int numOfPairs = 10;  String[][] array = new String[numOfPairs][2]; for(int i = 0; i < array.length; i++){     for(int j = 0; j < array[i].length; j++){         array[i] = new String[2];         array[i][0] = "original word";         array[i][1] = "rearranged word";     }    } 

Does this give you a hint?

May be this will be usefull for u: ReGExp on-line editor

Why are you wrapping the $_POST array in an array?

You can access your "id" and "value" arrays using the following

// assuming the appropriate isset() checks for $_POST['id'] and $_POST['value']

$ids = $_POST['id'];
$values = $_POST['value'];

foreach ($ids as $idx => $id) {
    // ...
}

foreach ($values as $idx => $value) {
    // ...
}

Well to create extra elements we can use :after, :before (so we don’t have to change the HTML that much). Then for radio buttons and checkboxes we can use :checked. There are a few other pseudo elements we can use as well (such as :hover). Using a mixture of these we can create some pretty cool custom forms. check this

Data validation drop down

There is a list option in Data validation. If this is combined with a VLOOKUP formula you would be able to convert the selected value into a number.

The steps in Excel 2010 are:

• Create your list with matching values.
• On the Data tab choose Data Validation
• The Data validation form will be displayed
• Set the Allow dropdown to List
• Set the Source range to the first part of your list
• Click on OK (User messages can be added if required)

In a cell enter a formula like this

=VLOOKUP(A2,$D$3:$E$5,2,FALSE)

which will return the matching value from the second part of your list.

Form control drop down

Alternatively, Form controls can be placed on a worksheet. They can be linked to a range and return the position number of the selected value to a specific cell.

The steps in Excel 2010 are:

• Create your list of data in a worksheet
• Click on the Developer tab and dropdown on the Insert option
• In the Form section choose Combo box or List box
• Use the mouse to draw the box on the worksheet
• Right click on the box and select Format control
• The Format control form will be displayed
• Click on the Control tab
• Set the Input range to your list of data
• Set the Cell link range to the cell where you want the number of the selected item to appear
• Click on OK

git add B # Add it to the index
git reset A # Remove it from the index
git commit # Commit the index

If the command sha256sum is not available (on Mac OS X v10.9 (Mavericks) for example), you can use:

echo -n "foobar" | shasum -a 256

Java 9 - JEP 259: Stack-Walking API

JEP 259 provides an efficient standard API for stack walking that allows easy filtering of, and lazy access to, the information in stack traces. Before Stack-Walking API, common ways of accessing stack frames were:

Throwable::getStackTrace and Thread::getStackTrace return an array of StackTraceElement objects, which contain the class name and method name of each stack-trace element.

SecurityManager::getClassContext is a protected method, which allows a SecurityManager subclass to access the class context.

JDK-internal sun.reflect.Reflection::getCallerClass method which you shouldn't use anyway

Using these APIs are usually inefficient:

These APIs require the VM to eagerly capture a snapshot of the entire stack, and they return information representing the entire stack. There is no way to avoid the cost of examining all the frames if the caller is only interested in the top few frames on the stack.

In order to find the immediate caller's class, first obtain a StackWalker:

StackWalker walker = StackWalker
                           .getInstance(StackWalker.Option.RETAIN_CLASS_REFERENCE);

Then either call the getCallerClass():

Class<?> callerClass = walker.getCallerClass();

or walk the StackFrames and get the first preceding StackFrame:

walker.walk(frames -> frames
      .map(StackWalker.StackFrame::getDeclaringClass)
      .skip(1)
      .findFirst());

Here's what's this TS snippet compiled into (via TS Playground):

define(["require", "exports"], function(require, exports) {
    var Library = (function () {
        function Library() {
        }
        Library.BOOK_SHELF_NONE = "None";
        Library.BOOK_SHELF_FULL = "Full";
        return Library;
    })();
    exports.Library = Library;
});

As you see, both properties defined as public static are simply attached to the exported function (as its properties); therefore they should be accessible as long as you properly access the function itself.

I faced the same problem, tried the first answer but something was missing.

If you guys are using Webpack, your css will be loaded as a style tag which is not supported by respond.js, it needs a file, so make sure bootstrap is loaded as a css file

Personally I used extract-text-webpack-plugin

const webpack = require("webpack")
const ExtractTextPlugin = require("extract-text-webpack-plugin")
const path = require("path")

module.exports = {
    context: __dirname+"/src",
    entry: "./index.js",
    output: {
        filename: "./dist/bundle.js",
        path: __dirname
    },
    plugins: [
        ...,
        new ExtractTextPlugin("./dist/bootstrap.css", {
            allChunks: true
        })
    ],
    module: {
        loaders: [
            ...,
            // your css loader excluding bootstrap
            {
                test: /\.css$/,
                loader: "style!css",
                exclude: [
                    path.resolve(__dirname, "node_modules/bootstrap/dist/css/bootstrap.css")
                ]
            },

            {
                // loads bootstrap as a file, change path accordingly if needs be, path needs to be absolute
                include: [
                    path.resolve(__dirname, "node_modules/bootstrap/dist/css/bootstrap.css")
                ],
                loader: ExtractTextPlugin.extract("style-loader", "css-loader?minimize")
            }
        ]
    }
}

use /// to begin each line of the comment and have the comment contain the appropriate xml for the meta data reader.

public void SayHello();

Although personally, I believe that these comments are usually misguided, unless you are developing classes where the code cannot be read by its consumers.

Just specifying the uri endpoint worked for me, bower 1.3.9

  "dependencies": {
    "jquery.cookie": "latest",
    "everestjs": "http://www.everestjs.net/static/st.v2.js"
  }

Running bower install, I received following output:

bower new           version for http://www.everestjs.net/static/st.v2.js#*
bower resolve       http://www.everestjs.net/static/st.v2.js#*
bower download      http://www.everestjs.net/static/st.v2.js

You could also try updating bower

• npm update -g bower

According to documentation: the following types of urls are supported:

http://example.com/script.js
http://example.com/style.css
http://example.com/package.zip (contents will be extracted)
http://example.com/package.tar (contents will be extracted)

There are at least two ways for achieving this in base graph (my examples are for the x-axis, but work the same for the y-axis):

1. Use par(xaxp = c(x1, x2, n)) or plot(..., xaxp = c(x1, x2, n)) to define the position (x1 & x2) of the extreme tick marks and the number of intervals between the tick marks (n). Accordingly, n+1 is the number of tick marks drawn. (This works only if you use no logarithmic scale, for the behavior with logarithmic scales see ?par.)

2. You can suppress the drawing of the axis altogether and add the tick marks later with axis().
   To suppress the drawing of the axis use plot(... , xaxt = "n").
   Then call axis() with side, at, and labels: axis(side = 1, at = v1, labels = v2). With side referring to the side of the axis (1 = x-axis, 2 = y-axis), v1 being a vector containing the position of the ticks (e.g., c(1, 3, 5) if your axis ranges from 0 to 6 and you want three marks), and v2 a vector containing the labels for the specified tick marks (must be of same length as v1, e.g., c("group a", "group b", "group c")). See ?axis and my updated answer to a post on stats.stackexchange for an example of this method.

If you are using ES6 Classes and ControllerAs syntax, you need to do something slightly different.

See the snippet below and note that vm is the ControllerAs value of the parent Controller as used in the parent HTML

myApp.directive('name', function() {
  return {
    // no scope definition
    link : function(scope, element, attrs, ngModel) {

        scope.vm.func(...)

Casting is not a mathematical operation and doesn't behave as such. Try

int y = (int)round(x);

The below answer is good:

grep -r -i --include \*.h --include \*.cpp CP_Image ~/path[12345] | mailx -s GREP [email protected]

But can be updated to:

grep -r -i --include \*.{h,cpp} CP_Image ~/path[12345] | mailx -s GREP [email protected]

Which can be more simple.

It is varchar and not var_char

CREATE DATABASE IF NOT EXISTS courses;

USE courses;

CREATE TABLE IF NOT EXISTS teachers(
    id INT(10) UNSIGNED PRIMARY KEY NOT NULL AUTO_INCREMENT,
    name VARCHAR(50) NOT NULL,
    addr VARCHAR(255) NOT NULL,
    phone INT NOT NULL
);

You should use a SQL tool to visualize possbile errors like MySQL Workbench.

I'm using this to address the security implications noted in @CMS's answer.

// example 1: www.example.com/index.html#foo

// load correct subpage from URL hash if it exists
$(window).on('load', function () {
    var hash = window.location.hash;
    if (hash) {
        hash = hash.replace('#',''); // strip the # at the beginning of the string
        hash = hash.replace(/([^a-z0-9]+)/gi, '-'); // strip all non-alphanumeric characters
        hash = '#' + hash; // hash now equals #foo with example 1

        // do stuff with hash
        $( 'ul' + hash + ':first' ).show();
        // etc...
    }
});

The precise wording of the question makes me think it's impossible.

return to me means you have a function, which you have passed a string as a parameter.

You cannot change this parameter. Assigning to it will only change the value of the parameter within the function, not the passed in string. E.g.

>>> def removeAndReturnLastCharacter(a):
        c = a[-1]
        a = a[:-1]
        return c

>>> b = "Hello, Gaukler!"
>>> removeAndReturnLastCharacter(b)
!

>>> b    # b has not been changed
Hello, Gaukler!

I got this error message, because I was migrating an application from SVN to GitHub and it's not enough to invoke a git init in the location of the source code checked out from SVN, but you need to invoke a git svn clone in order to have all the commit history. This way the two source codes on GitHub will have a mutual history and I was able to open pull requests.

Reloading existing classes with existing data is likely to break things.

You can load new code into new class loaders relatively easily:

ClassLoader loader = URLClassLoader.newInstance(
    new URL[] { yourURL },
    getClass().getClassLoader()
);
Class<?> clazz = Class.forName("mypackage.MyClass", true, loader);
Class<? extends Runnable> runClass = clazz.asSubclass(Runnable.class);
// Avoid Class.newInstance, for it is evil.
Constructor<? extends Runnable> ctor = runClass.getConstructor();
Runnable doRun = ctor.newInstance();
doRun.run();

Class loaders no longer used can be garbage collected (unless there is a memory leak, as is often the case with using ThreadLocal, JDBC drivers, java.beans, etc).

If you want to keep the object data, then I suggest a persistence mechanism such as Serialisation, or whatever you are used to.

Of course debugging systems can do fancier things, but are more hacky and less reliable.

It is possible to add new classes into a class loader. For instance, using URLClassLoader.addURL. However, if a class fails to load (because, say, you haven't added it), then it will never load in that class loader instance.

Most of the time this is due to an incorrect export/import.

Common error:

// File: LeComponent.js
export class LeComponent extends React.Component { ... }

// File: App.js
import LeComponent from './LeComponent';

Possible option:

// File: LeComponent.js 
export default class LeComponent extends React.Component { ... }

// File: App.js
import LeComponent from './LeComponent';

There are a few ways it could be wrong, but that error is because of an import/export mismatch 60% of the time, everytime.

Edit

Typically you should get a stacktrace that indicates an approximate location of where the failure occurs. This generally follows straight after the message you have in your original question.

If it doesn't show, it might be worth investigating why (it might be a build setting that you're missing). Regardless, if it doesn't show, the only course of action is narrowing down where the export/import is failing.

Sadly, the only way to do it, without a stacktrace is to manually remove each module/submodule until you don't get the error anymore, then work your way back up the stack.

Edit 2

Via comments, it was indeed an import issue, specifically importing a module that didn't exist

this will be more efficient:

public static class StringExtension
{
    public static string clean(this string s)
    {
        return new StringBuilder(s)
              .Replace("&", "and")
              .Replace(",", "")
              .Replace("  ", " ")
              .Replace(" ", "-")
              .Replace("'", "")
              .Replace(".", "")
              .Replace("eacute;", "é")
              .ToString()
              .ToLower();
    }
}

Your code could be reduced to

SimpleDateFormat sdf = new SimpleDateFormat("dd/MM/yyyy");
Date strDate = sdf.parse(valid_until);
if (new Date().after(strDate)) {
    catalog_outdated = 1;
}

or

SimpleDateFormat sdf = new SimpleDateFormat("dd/MM/yyyy");
Date strDate = sdf.parse(valid_until);
if (System.currentTimeMillis() > strDate.getTime()) {
    catalog_outdated = 1;
}

For Windows & Mac Users, there is another pretty easy and friendly way to change the mapping port:

1. download kitematic

2. go to the settings page of the container, on the ports tab, you can directly modify the published port there.

3. start the container again

move c:\Sourcefoldernam\*.* e:\destinationFolder

^ This did not work for me for some reason

But when I tried using quotation marks, it suddenly worked:

move "c:\Sourcefoldernam\*.*" "e:\destinationFolder"

I think its because my directory had spaces in one of the folders. So if it doesn't work for you, try with quotation marks!

String currency = "135.69";
System.out.println(new BigDecimal(currency));

//will print 135.69

You could access the underlying array and call its tolist method:

>>> df = pd.DataFrame([[1,2,3],[3,4,5]])
>>> lol = df.values.tolist()
>>> lol
[[1L, 2L, 3L], [3L, 4L, 5L]]

n = str(input("Enter the number\n"))

list1 = []

for each_number in n:

        list1.append(int(each_number))

print(sum(list1))

I have just cooked up another solution for this, where it's not longer necessary to use a -much to high- max-height value. It needs a few lines of javascript code to calculate the inner height of the collapsed DIV but after that, it's all CSS.

1) Fetching and setting height

Fetch the inner height of the collapsed element (using scrollHeight). My element has a class .section__accordeon__content and I actually run this in a forEach() loop to set the height for all panels, but you get the idea.

document.querySelectorAll( '.section__accordeon__content' ).style.cssText = "--accordeon-height: " + accordeonPanel.scrollHeight + "px";

2) Use the CSS variable to expand the active item

Next, use the CSS variable to set the max-height value when the item has an .active class.

.section__accordeon__content.active {
  max-height: var(--accordeon-height);
}

Final example

So the full example goes like this: first loop through all accordeon panels and store their scrollHeight values as CSS variables. Next use the CSS variable as the max-height value on the active/expanded/open state of the element.

Javascript:

document.querySelectorAll( '.section__accordeon__content' ).forEach(
  function( accordeonPanel ) {
    accordeonPanel.style.cssText = "--accordeon-height: " + accordeonPanel.scrollHeight + "px";
  }
);

CSS:

.section__accordeon__content {
  max-height: 0px;
  overflow: hidden;
  transition: all 425ms cubic-bezier(0.465, 0.183, 0.153, 0.946);
}

.section__accordeon__content.active {
  max-height: var(--accordeon-height);
}

And there you have it. A adaptive max-height animation using only CSS and a few lines of JavaScript code (no jQuery required).

Hope this helps someone in the future (or my future self for reference).

well in mysql 5.5 , like operator is insensitive...so if your vale is elm or ELM or Elm or eLM or any other , and you use like '%elm%' , it will list all the matching values.

I cant say about earlier versions of mysql.

If you go in Oracle , like work as case-sensitive , so if you type like '%elm%' , it will go only for this and ignore uppercases..

Strange , but this is how it is :)

A little hint. The message often appears during rename operation. The quick workaround for me is pressing Ctrl-Y (redo shortcut) after message confirmation. It works only if the renaming affects a single file.

When you run the command git checkout commit_id then HEAD detached from 13ca5593d(say commit-id) and branch will be on longer available.

Move back to previous location run the command step wise -

1. git pull origin branch_name (say master)
2. git checkout branch_name
3. git pull origin branch_name

You will be back to the previous location with an updated commit from the remote repository.

You've tagged this question with the ssl tag, and SSL is the answer. Curious.

Here '~' refers to the root directory ,where Home is controller and Download_Excel_File is actionmethod

 <a href="~/Home/Download_Excel_File" />

Yes, in my perspective there is no reason why you should write your own. Most of the Open Source BPM/Workflow frameworks are extremely flexible, you just need to learn the basics. If you choose jBPM you will get much more than a simple workflow engine, so it depends what are you trying to build.

Cheers

For the impatient:

UPDATE target AS t
INNER JOIN (
  SELECT s.id, COUNT(*) AS count
  FROM source_grouped AS s
  -- WHERE s.custom_condition IS (true)
  GROUP BY s.id
) AS aggregate ON aggregate.id = t.id
SET t.count = aggregate.count

That's @mellamokb's answer, as above, reduced to the max.

try this.. I had it too but now it solved in XP..

C:\ YourFolder >set path=C:\Program Files\Java\jdk1.7.0_09\bin;

|| returns a boolean value by OR'ing two values (Thats why its known as a LOGICAL or)

IE:

if (A || B) 

Would return true if either A or B is true, or false if they are both false.

| is an operator that performs a bitwise operation on two values. To better understand bitwise operations, you can read here:

http://en.wikipedia.org/wiki/Bitwise_operation

Using list comprehension:

print [x for x in item if x not in Z]

or using filter function :

filter(lambda x: x not in Z, item)

Using set in any form may create a bug if the list being checked contains non-unique elements, e.g.:

print item

Out[39]: [0, 1, 1, 2, 3, 4, 5, 6, 7, 8, 9]

print Z

Out[40]: [3, 4, 5, 6]

set(item) - set(Z)

Out[41]: {0, 1, 2, 7, 8, 9}

vs list comprehension as above

print [x for x in item if x not in Z]

Out[38]: [0, 1, 1, 2, 7, 8, 9]

or filter function:

filter(lambda x: x not in Z, item)

Out[38]: [0, 1, 1, 2, 7, 8, 9]

I found that I initialised my slider using inline script in the body, which meant it was being called before slick.js had been loaded. I fixed using inline JS in the footer to initialise the slider after including the slick.js file.

        slidesToShow: 1,

You import the function from outside the main instance, and don't add it to the methods block. so the context of this is not the vm.

Either do this:

ready() {
  checkAuth.call(this)
}

or add the method to your methods first (which will make Vue bind this correctly for you) and call this method:

methods: {
  checkAuth: checkAuth
},
ready() {
  this.checkAuth()
}

On a Mac:

I was running this out of the Maven com.github.eirslett Frontend Plugin when I had the same error.

Eventually I had to:

Install Node.js via the installer download here: http://nodejs.org/

Delete all the node/ and node_modules/ folders from within my maven build structure.

Please note: this answer is obsolete, the functionality was removed from iOS simulator.

I have just found that you don't need to copy the mobile application bundle to the iPhone Simulator's folder to start it on the simulator, as described in the forum. That way you need to click on the app to get it started, not confortable when you want to do testing and start the app numerous times.

There are undocumented command line parameters for the iOS Simulator, which can be used for such purposes. The one you are looking for is: -SimulateApplication

An example command line starting up YourFavouriteApp:

/Developer/Platforms/iPhoneSimulator.platform/Developer/Applications/iPhone\ Simulator.app/Contents/MacOS/iPhone\ Simulator -SimulateApplication path_to_your_app/YourFavouriteApp.app/YourFavouriteApp

This will start up your application without any installation and works with iOS Simulator 4.2 at least. You cannot reach the home menu, though.

There are other unpublished command line parameters, like switching the SDK. Happy hunting for those...

you can use:

define("PATH_ROOT", dirname(__FILE__));
include_once PATH_ROOT . "/PoliticalForum/headerSite.php";

SQL Server drops and recreates the tables only if you:

• Add a new column
• Change the Allow Nulls setting for a column
• Change the column order in the table
• Change the column data type

Using ALTER is safer, as in case the metadata is lost while you re-create the table, your data will be lost.

A few comments:

import sun.misc.*; Don't do this. It is non-standard and not guaranteed to be the same between implementations. There are other libraries with Base64 conversion available.

byte[] encVal = c.doFinal(Data.getBytes()); You are relying on the default character encoding here. Always specify what character encoding you are using: byte[] encVal = c.doFinal(Data.getBytes("UTF-8")); Defaults might be different in different places.

As @thegrinner pointed out, you need to explicitly check the length of your byte arrays. If there is a discrepancy, then compare them byte by byte to see where the difference is creeping in.

Quick Fix for Development

For development, you could just disable the cache in Chrome Dev Tools (Disabling Chrome cache for website development). The cache disabling happens only if the dev tools dialog is open, so you need not worry about toggling this option every time you do regular browsing.

Note: Using 'urlArgs' is the proper solution in production so that users get the latest code. But it makes debugging difficult because chrome invalidates breakpoints with every refresh (because its a 'new' file being served each time).

use: opener.document.<id of document>.innerHTML = xmlhttp.responseText;

Three years later, I ran into the same problem. Here's my solution, everybody feel free to cut-n-paste. The simplest things keep us up all night! Running on an ATMega, and Adafruit Feather M0:

void setup() {
  // turn on Serial so we can see...
  Serial.begin(9600);

  // the culprit:
  uint8_t my_str[6];    // an array big enough for a 5 character string

  // give it something so we can see what it's doing
  my_str[0] = 'H';
  my_str[1] = 'e';
  my_str[2] = 'l';
  my_str[3] = 'l';
  my_str[4] = 'o';
  my_str[5] = 0;  // be sure to set the null terminator!!!

  // can we see it?
  Serial.println((char*)my_str);

  // can we do logical operations with it as-is?
  Serial.println((char*)my_str == 'Hello');

  // okay, it can't; wrong data type (and no terminator!), so let's do this:
  String str((char*)my_str);

  // can we see it now?
  Serial.println(str);

  // make comparisons
  Serial.println(str == 'Hello');

  // one more time just because
  Serial.println(str == "Hello");

  // one last thing...!
  Serial.println(sizeof(str));
}

void loop() {
  // nothing
}

And we get:

Hello    // as expected
0        // no surprise; wrong data type and no terminator in comparison value
Hello    // also, as expected
1        // YAY!
1        // YAY!
6        // as expected

Hope this helps someone!

Are you missing the 'SET' statement when assigning to your variables in the IF .. ELSE block?

Intent serviceIntent = new Intent(this,YourActivity.class);

startService(serviceIntent);

add service in manifist

<service android:enabled="true" android:name="YourActivity.class" />

for running service on oreo and greater devices use for ground service and show notification to user

or use geofencing service for location update in background reference http://stackoverflow.com/questions/tagged/google-play-services

TextPad will allow you to perform this operation.

example:

test this sentence

Find what: \([^ ]*\) \(.*\) Replace with: \U\1\E \2

the \U will cause all following chars to be upper

the \E will turn off the \U

the result will be:

TEST this sentence

You can use curl instead.

version=1.2.3
artifact="artifact"
repoId=repositoryId
groupId=org/myorg
REPO_URL=http://localhost:8081/nexus

curl -u username:password --upload-file filename.tgz $REPO_URL/content/repositories/$repoId/$groupId/$artefact/$version/$artifact-$version.tgz

No, the powers that be at Google chose not to support that.

@Sheridan thx.. if I try your example with "DisplayedImagePath" on both sides, it works with absolute path as you show.

As for the relative paths, this is how I always connect relative paths, I first include the subdirectory (!) and the image file in my project.. then I use ~ character to denote the bin-path..

    public string DisplayedImagePath
    {
        get { return @"~\..\images\osc.png"; }
    }

This was tested, see below my Solution Explorer in VS2015..

)

Note: if you want a Click event, use the Button tag around the image,

<Button Click="image_Click" Width="128" Height="128"  Grid.Row="2" VerticalAlignment="Top" HorizontalAlignment="Left">_x000D_
  <Image x:Name="image" Source="{Binding DisplayedImagePath}" Margin="0,0,0,0" />_x000D_
</Button>

If you don't mind a third party dependency, there is a class named Collectors2 in Eclipse Collections which contains methods returning Collectors for summing and summarizing BigDecimal and BigInteger. These methods take a Function as a parameter so you can extract a BigDecimal or BigInteger value from an object.

List<BigDecimal> list = mList(
        BigDecimal.valueOf(0.1),
        BigDecimal.valueOf(1.1),
        BigDecimal.valueOf(2.1),
        BigDecimal.valueOf(0.1));

BigDecimal sum =
        list.stream().collect(Collectors2.summingBigDecimal(e -> e));
Assert.assertEquals(BigDecimal.valueOf(3.4), sum);

BigDecimalSummaryStatistics statistics =
        list.stream().collect(Collectors2.summarizingBigDecimal(e -> e));
Assert.assertEquals(BigDecimal.valueOf(3.4), statistics.getSum());
Assert.assertEquals(BigDecimal.valueOf(0.1), statistics.getMin());
Assert.assertEquals(BigDecimal.valueOf(2.1), statistics.getMax());
Assert.assertEquals(BigDecimal.valueOf(0.85), statistics.getAverage());

Note: I am a committer for Eclipse Collections.

Just for yumers,

yum install php-mcrypt
service httpd restart
chown -R apache:apache apppath

Maybe you need install remi repo

Note to under

connetionString =@"server=XXX;Trusted_Connection=yes;database=yourDB;";

Note: XXX = . OR .\SQLEXPRESS OR .\MSSQLSERVER OR (local)\SQLEXPRESS OR (localdb)\v11.0 &...

you can replace 'server' with 'Data Source'

too you can replace 'database' with 'Initial Catalog'

Sample:

 connetionString =@"server=.\SQLEXPRESS;Trusted_Connection=yes;Initial Catalog=books;";

I just wanted to add to the William Smash solution as I couldn't get to his blog so answers which may have been in there to my simple questions could not be found.

Took me a while to realise, but maybe I was just having a moment...

If you haven't had to do so already you'll need to add a reference to System.Windows.Forms in the project properties.

Also you'll need to add

Imports System.Windows.Forms 

to the file where you're adding the override class.

For OnPaintBackground you'll need to add a reference for System.Drawing then

Imports System.Drawing.Printing.PrintEventArgs

I use Portable winpython in Windows, it includes IPython QT console, I could achieve the following.

>>>print ("??")
??

>>>print ("????")
????

>>>str = "??"


>>>print (str)
??

your console interpreter should support unicode in order to show unicode characters.

I just found a new trick to center a box in the middle of the screen even if you don't have fixed dimensions. Let's say you would like a box 60% width / 60% height. The way to make it centered is by creating 2 boxes: a "container" box that position left: 50% top :50%, and a "text" box inside with reverse position left: -50%; top :-50%;

It works and it's cross browser compatible.

Check out the code below, you probably get a better explanation:

  jQuery('#message').fadeOut();_x000D_

If you can save the workbook then you have the option to use ADO and Jet/ACE to treat the workbook as a database, and execute SQL against the sheet.

The MSDN information on how to hit Excel using ADO can be found here.

If you prefer to use style='{', fmt="{asctime}.{msecs:0<3.0f}" will 0-pad your microseconds to three places for consistency.

To avoid confusion, paraphrasing both question and answer. I am assuming that user who posted this question wanted to save dictionary type object in JSON file format but when the user used json.dump, this method dumped all its content in one line. Instead, he wanted to record each dictionary entry on a new line. To achieve this use:

with g as outfile:
  json.dump(hostDict, outfile,indent=2)

Using indent = 2 helped me to dump each dictionary entry on a new line. Thank you @agf. Rewriting this answer to avoid confusion.

As per String literals:

String literals can be enclosed within single quotes (i.e. '...') or double quotes (i.e. "..."). They can also be enclosed in matching groups of three single or double quotes (these are generally referred to as triple-quoted strings).

The backslash character (i.e. \) is used to escape characters which otherwise will have a special meaning, such as newline, backslash itself, or the quote character. String literals may optionally be prefixed with a letter r or R. Such strings are called raw strings and use different rules for backslash escape sequences.

In triple-quoted strings, unescaped newlines and quotes are allowed, except that the three unescaped quotes in a row terminate the string.

Unless an r or R prefix is present, escape sequences in strings are interpreted according to rules similar to those used by Standard C.

So ideally you need to replace the line:

data = open("C:\Users\miche\Documents\school\jaar2\MIK\2.6\vektis_agb_zorgverlener")

To any one of the following characters:

• Using raw prefix and single quotes (i.e. '...'):

    data = open(r'C:\Users\miche\Documents\school\jaar2\MIK\2.6\vektis_agb_zorgverlener')
  

• Using double quotes (i.e. "...") and escaping backslash character (i.e. \):

    data = open("C:\\Users\\miche\\Documents\\school\\jaar2\\MIK\\2.6\\vektis_agb_zorgverlener")
  

• Using double quotes (i.e. "...") and forwardslash character (i.e. /):

    data = open("C:/Users/miche/Documents/school/jaar2/MIK/2.6/vektis_agb_zorgverlener")
  

Custom serialization and deserialization.

"from_json" (class method) builds a Model object based on json data.

"deserialize" could be called only on instance, and merge all data from json into Model instance.

"serialize" - recursive serialization

__write_only__ property is needed to define write only properties ("password_hash" for example).

class Serializable(object):
    __exclude__ = ('id',)
    __include__ = ()
    __write_only__ = ()

    @classmethod
    def from_json(cls, json, selfObj=None):
        if selfObj is None:
            self = cls()
        else:
            self = selfObj
        exclude = (cls.__exclude__ or ()) + Serializable.__exclude__
        include = cls.__include__ or ()
        if json:
            for prop, value in json.iteritems():
                # ignore all non user data, e.g. only
                if (not (prop in exclude) | (prop in include)) and isinstance(
                        getattr(cls, prop, None), QueryableAttribute):
                    setattr(self, prop, value)
        return self

    def deserialize(self, json):
        if not json:
            return None
        return self.__class__.from_json(json, selfObj=self)

    @classmethod
    def serialize_list(cls, object_list=[]):
        output = []
        for li in object_list:
            if isinstance(li, Serializable):
                output.append(li.serialize())
            else:
                output.append(li)
        return output

    def serialize(self, **kwargs):

        # init write only props
        if len(getattr(self.__class__, '__write_only__', ())) == 0:
            self.__class__.__write_only__ = ()
        dictionary = {}
        expand = kwargs.get('expand', ()) or ()
        prop = 'props'
        if expand:
            # expand all the fields
            for key in expand:
                getattr(self, key)
        iterable = self.__dict__.items()
        is_custom_property_set = False
        # include only properties passed as parameter
        if (prop in kwargs) and (kwargs.get(prop, None) is not None):
            is_custom_property_set = True
            iterable = kwargs.get(prop, None)
        # loop trough all accessible properties
        for key in iterable:
            accessor = key
            if isinstance(key, tuple):
                accessor = key[0]
            if not (accessor in self.__class__.__write_only__) and not accessor.startswith('_'):
                # force select from db to be able get relationships
                if is_custom_property_set:
                    getattr(self, accessor, None)
                if isinstance(self.__dict__.get(accessor), list):
                    dictionary[accessor] = self.__class__.serialize_list(object_list=self.__dict__.get(accessor))
                # check if those properties are read only
                elif isinstance(self.__dict__.get(accessor), Serializable):
                    dictionary[accessor] = self.__dict__.get(accessor).serialize()
                else:
                    dictionary[accessor] = self.__dict__.get(accessor)
        return dictionary

querySelectorAll with standard class selectors also works for this.

document.querySelectorAll('.class1.class2');

var student = [];
var obj = {
    'first_name': name,
    'last_name': name,
    'age': age,
}
student.push(obj);

Format String Syntax.

https://docs.python.org/3/library/string.html#formatstrings

from math import pi
var1, var2, var3, var4 = pi, pi*2, pi*3, pi*4
'{:0.2f}, kg={:0.2f}, lb={:0.2f}, gal={:0.2f}'.format(var1, var2, var3, var4)

The output would be:

'3.14, kg=6.28, lb=9.42, gal=12.57'

I know this is quite an old question -

A = [[1, 2, 3],
     [4, 5, 6],
     [7, 8, 9]]

Let's say, you want to extract the first 2 rows and first 3 columns

A_NEW = A[0:2, 0:3]
A_NEW = [[1, 2, 3],
         [4, 5, 6]]

Understanding the syntax

A_NEW = A[start_index_row : stop_index_row, 
          start_index_column : stop_index_column)]

If one wants row 2 and column 2 and 3

A_NEW = A[1:2, 1:3]

Reference the numpy indexing and slicing article - Indexing & Slicing

Case: If you need to ignore the merge commit created by default, follow these steps.

Say, a new feature branch is checked out from master having 2 commits already,

• "Added A" , "Added B"

Checkout a new feature_branch

• "Added C" , "Added D"

Feature branch then adds two commits-->

• "Added E", "Added F"

Now if you want to merge feature_branch changes to master, Do git merge feature_branch sitting on the master.

This will add all commits into master branch (4 in master + 2 in feature_branch = total 6) + an extra merge commit something like 'Merge branch 'feature_branch'' as the master is diverged.

If you really need to ignore these commits (those made in FB) and add the whole changes made in feature_branch as a single commit like 'Integrated feature branch changes into master', Run git merge feature_merge --no-commit.

With --no-commit, it perform the merge and stop just before creating a merge commit, We will have all the added changes in feature branch now in master and get a chance to create a new commit as our own.

for me I simply had to add configure my git username and email with the following commands:

git config --global user.email "[email protected]"
git config --global user.name "Your Name"

To get newly created branches

git fetch

To switch into another branch

git checkout BranchName

You need to make sure that you add forward slash before your link to socket.io:

<script src="/socket.io/socket.io.js"></script>

Then in the view/controller just do:

var socket = io.connect()

That should solve your problem.
