<htmltag id=’elementId’ data-ZZZZ’=’@Html.Raw(Json.Encode(Model))’ />

Refer https://highspeedlowdrag.wordpress.com/2014/08/23/mvc-data-to-jquery-data/

I did below and it works like charm.

<input id="hdnElement" class="hdnElement" type="hidden" value='@Html.Raw(Json.Encode(Model))'>

This happened to me when I tried to install a newer version of PHP. After finding that I also would need to reconfigure Apache for that I switched back to the old PHP version. Here the solution which worked for me:

change the httpd.conf to the correct versions:

 PHPIniDir ...
 LoadModule php5_module ...

Changed the

PATH - Environment Variable

When that does not take any effect

rename or delete the new PHP(-Version)-Folder

For some reason the last step did the trick for me. Even after a restart it did not have an effect before doing this.

In Pandas, I like to use the shape attribute to get number of rows.

df[df.A > 0].shape[0]

gives the number of rows matching the condition A > 0, as desired.

You will need to use ProcessStartInfo with RedirectStandardOutput enabled - then you can read the output stream. You might find it easier to use ">" to redirect the output to a file (via the OS), and then simply read the file.

[edit: like what Ray did: +1]

Neither of the answers resolved the issue for me. Even after I had installed a new version of Tortoise SVN + Ccleaner.

Seems that there is a folder in AppData\Roaming\Subversion that contains all configuration of Tortoise SVN. You need to delete it all and restart Tortoise SVN.

Hope this helps someone as the ultimate solution.

To trim my strings from the both sides I use the oldie but the gooody ;) It can trim anything with ascii less than a space, meaning that the control chars will be trimmed also !

char *trimAll(char *strData)
{
  unsigned int L = strlen(strData);
  if(L > 0){ L--; }else{ return strData; }
  size_t S = 0, E = L;
  while((!(strData[S] > ' ') || !(strData[E] > ' ')) && (S >= 0) && (S <= L) && (E >= 0) && (E <= L))
  {
    if(strData[S] <= ' '){ S++; }
    if(strData[E] <= ' '){ E--; }
  }
  if(S == 0 && E == L){ return strData; } // Nothing to be done
  if((S >= 0) && (S <= L) && (E >= 0) && (E <= L)){
    L = E - S + 1;
    memmove(strData,&strData[S],L); strData[L] = '\0';
  }else{ strData[0] = '\0'; }
  return strData;
}

I will side with nategood's answer as it is complete and it seemed to have please your needs. Though, I would like to add a comment on identifying multiple (1 or more) resource that way:

http://our.api.com/Product/101404,7267261

In doing so, you:

Complexify the clients by forcing them to interpret your response as an array, which to me is counter intuitive if I make the following request: http://our.api.com/Product/101404

Create redundant APIs with one API for getting all products and the one above for getting 1 or many. Since you shouldn't show more than 1 page of details to a user for the sake of UX, I believe having more than 1 ID would be useless and purely used for filtering the products.

It might not be that problematic, but you will either have to handle this yourself server side by returning a single entity (by verifying if your response contains one or more) or let clients manage it.

Example

I want to order a book from Amazing. I know exactly which book it is and I see it in the listing when navigating for Horror books:

1. 10 000 amazing lines, 0 amazing test
2. The return of the amazing monster
3. Let's duplicate amazing code
4. The amazing beginning of the end

After selecting the second book, I am redirected to a page detailing the book part of a list:

--------------------------------------------
Book #1
--------------------------------------------
    Title: The return of the amazing monster
    Summary:
    Pages:
    Publisher:
--------------------------------------------

Or in a page giving me the full details of that book only?

---------------------------------
The return of the amazing monster
---------------------------------
Summary:
Pages:
Publisher:
---------------------------------

My Opinion

I would suggest using the ID in the path variable when unicity is guarantied when getting this resource's details. For example, the APIs below suggest multiple ways to get the details for a specific resource (assuming a product has a unique ID and a spec for that product has a unique name and you can navigate top down):

/products/{id}
/products/{id}/specs/{name}

The moment you need more than 1 resource, I would suggest filtering from a larger collection. For the same example:

/products?ids=

Of course, this is my opinion as it is not imposed.

to Vilx-:

var table = row.parentNode;
while ( table && table.tagName != 'TABLE' )
    table = table.parentNode;

and what if row.parentNode is TBODY?

You should check it out first, and after that do while by .tBodies, probably

Try this command:

pip install pywin32

Note

If it gives the following error:

Could not find a version that satisfies the requirement pywin32>=223 (from pypiwin32) (from versions:)
No matching distribution found for pywin32>=223 (from pypiwin32)

upgrade 'pip', using:

pip install --upgrade pip

What about normal encoded white-space character?

 

This is a known issue. The problem is that a div tag has the style "overflow: auto" which apparently is not implemented well with WebKit which is used by Safari and Chrome (see Emanuele Greco's answer). I did not know how to take advantage of Emanuele's suggestion to use the RS:ReportViewerHost element, but I solved it using JavaScript.

Problem

Solution

Since "overflow: auto" is specified in the style attribute of the div element with id "ctl31_ctl10", we can't override it in a stylesheet file so I resorted to JavaScript. I appended the following code to "C:\Program Files\Microsoft SQL Server\MSRS10_50.MSSQLSERVER\Reporting Services\ReportManager\js\ReportingServices.js"

function FixSafari()
{    
    var element = document.getElementById("ctl31_ctl10");
    if (element) 
    {
        element.style.overflow = "visible";  //default overflow value
    }
}

// Code from http://stackoverflow.com/questions/9434/how-do-i-add-an-additional-window-onload-event-in-javascript
if (window.addEventListener) // W3C standard
{
    window.addEventListener('load', FixSafari, false); // NB **not** 'onload'
} 
else if (window.attachEvent) // Microsoft
{
    window.attachEvent('onload', FixSafari);
}

Note

There appears to be a solution for SSRS 2005 that I have not tried but I don't think it is applicable to SSRS 2008 because I can't find the "DocMapAndReportFrame" class.

 // Get calendar set to the current date and time
Calendar cal = Calendar.getInstance();

// Set time of calendar to 18:00
cal.set(Calendar.HOUR_OF_DAY, 18);
cal.set(Calendar.MINUTE, 0);
cal.set(Calendar.SECOND, 0);
cal.set(Calendar.MILLISECOND, 0);

// Check if current time is after 18:00 today
boolean afterSix = Calendar.getInstance().after(cal);

if (afterSix) {
    System.out.println("Go home, it's after 6 PM!");
}
else {
    System.out.println("Hello!");
}

Upgrading pip using 'pip install --upgrade pip' does not always work because of the dreaded cert issue: There was a problem confirming the ssl certificate: [SSL: TLSV1_ALERT_PROTOCOL_VERSION] tlsv1 alert protocol version

I like to use the one line command for virtual envs:

curl https://bootstrap.pypa.io/get-pip.py | python -

Or if you want to install it box wide you will need

curl https://bootstrap.pypa.io/get-pip.py | sudo python -

you can give curl a -s flag if you want to silence the output when running in an automation script.

I use netfox. It is very easy to use and integrate. You can use it on simulator and device. It shows all of the requests and responses. It supports JSON, XML, HTML, Image and Other types of responses. You can share requests, responses and full log by IOS default sharing formats (Gmail, WhatsApp, email, slack, sms, etc.)

You can check on GitHub: https://github.com/kasketis/netfox

Netfox provides a quick look on all executed network requests performed by your iOS or OSX app. It grabs all requests - of course yours, requests from 3rd party libraries (such as AFNetworking, Alamofire or else), UIWebViews, and more

I resolved it by setting the field blank:

Settings > Compiler > Java Compiler > Project bytecode version

Than IntelliJ uses the JDK default version.

Valerio is almost right with his solution, but there is some logical mistake.

you must firstly check wether angle2 is bigger than angle, before adding 360 at a negative.

otherwise you always have a bigger value than angle

So the correct solution is:

var west = calculateMin(data.longitudes);
var east = calculateMax(data.longitudes);
var angle = east - west;
var north = calculateMax(data.latitudes);
var south = calculateMin(data.latitudes);
var angle2 = north - south;
var zoomfactor;
var delta = 0;
var horizontal = false;

if(angle2 > angle) {
    angle = angle2;
    delta = 3;
}

if (angle < 0) {
    angle += 360;
}

zoomfactor = Math.floor(Math.log(960 * 360 / angle / GLOBE_WIDTH) / Math.LN2) - 2 - delta;

Delta is there, because i have a bigger width than height.

#map {
  float: right;
  width: 700px;
  height: 500px;
}
#list {
  float:left;
  width:200px;
  background: #eee;
  list-style: none;
  padding: 0;
}
#similar {
  float: left;
  clear: left;
  width: 200px;
  background: #000;
}

You are right, by creating object manually you are not letting Spring to perform autowiring. Consider managing your services by Spring as well:

@Component
public class MyServiceFactory {

    @Autowired
    private MyServiceOne myServiceOne;

    @Autowired
    private MyServiceTwo myServiceTwo;

    @Autowired
    private MyServiceThree myServiceThree;

    @Autowired
    private MyServiceDefault myServiceDefault;

    public static MyService getMyService(String service) {
        service = service.toLowerCase();

        if (service.equals("one")) {
            return myServiceOne;
        } else if (service.equals("two")) {
            return myServiceTwo;
        } else if (service.equals("three")) {
            return myServiceThree;
        } else {
            return myServiceDefault;
        }
    }
}

But I would consider the overall design to be rather poor. Wouldn't it better to have one general MyService implementation and pass one/two/three string as extra parameter to checkStatus()? What do you want to achieve?

@Component
public class MyServiceAdapter implements MyService {

    @Autowired
    private MyServiceOne myServiceOne;

    @Autowired
    private MyServiceTwo myServiceTwo;

    @Autowired
    private MyServiceThree myServiceThree;

    @Autowired
    private MyServiceDefault myServiceDefault;

    public boolean checkStatus(String service) {
        service = service.toLowerCase();

        if (service.equals("one")) {
            return myServiceOne.checkStatus();
        } else if (service.equals("two")) {
            return myServiceTwo.checkStatus();
        } else if (service.equals("three")) {
            return myServiceThree.checkStatus();
        } else {
            return myServiceDefault.checkStatus();
        }
    }
}

This is still poorly designed because adding new MyService implementation requires MyServiceAdapter modification as well (SRP violation). But this is actually a good starting point (hint: map and Strategy pattern).

You can't define static methods in an interface because static methods belongs to a class not to an instance of class, and interfaces are not Classes. Read more here.

However, If you want you can do this:

public class A {
  public static void methodX() {
  }
}

public class B extends A {
  public static void methodX() {
  }
}

In this case what you have is two classes with 2 distinct static methods called methodX().

stat -c %s file.txt

This command will give you the size of the file in bytes. You can learn more about why you should avoid parsing output of ls command over here: http://mywiki.wooledge.org/ParsingLs

If you have access to SQL Server 2016, you can use the FOR JSON (with INCLUDE_NULL_VALUES) option to get JSON output from a select statement. Copy the output, then in Visual Studio, paste special -> paste JSON as class.

Kind of a budget solution, but might save some time.

If you want to use classes:

class Singleton {
  constructor(name, age) {
    this.name = name;
    this.age = age;
    if(this.constructor.instance)
      return this.constructor.instance;
    this.constructor.instance = this;
  }
}
let x = new Singleton('s', 1);
let y = new Singleton('k', 2);

Output for the above will be:

console.log(x.name, x.age, y.name, y.age) // s 1 s 1

Another way of writing Singleton using function

function AnotherSingleton (name,age) {
  this.name = name;
  this.age = age;
  if(this.constructor.instance)
    return this.constructor.instance;
  this.constructor.instance = this;
}

let a = new AnotherSingleton('s', 1);
let b = new AnotherSingleton('k', 2);

Output for the above will be:

console.log(a.name, a.age, b.name, b.age) // s 1 s 1

Here is another way to separate your table header and table body:

thead th {
    background-color: #006DCC;
    color: white;
}

tbody td {
    background-color: #EEEEEE;
}

Have a look at this example for separation of head and body of table. JsFiddleLink

string Location = "C:\\Program Files\\hello.txt";

string FileName = Location.Substring(Location.LastIndexOf('\\') +
    1);

since 1.5.0 u can use the 'inline' keyword.

Example: @import (inline) "not-less-compatible.css";

You will use this when a CSS file may not be Less compatible; this is because although Less supports most known standards CSS, it does not support comments in some places and does not support all known CSS hacks without modifying the CSS. So you can use this to include the file in the output so that all CSS will be in one file.

A slightly clumsier but faster approach for larger datasets involves getting the counts for a column of interest, sorting the counts highest to lowest, and then de-duplicating on a subset to only retain the largest cases. The code example is following:

>>> import pandas as pd
>>> source = pd.DataFrame(
        {
            'Country': ['USA', 'USA', 'Russia', 'USA'], 
            'City': ['New-York', 'New-York', 'Sankt-Petersburg', 'New-York'],
            'Short name': ['NY', 'New', 'Spb', 'NY']
        }
    )
>>> grouped_df = source\
        .groupby(['Country','City','Short name'])[['Short name']]\
        .count()\
        .rename(columns={'Short name':'count'})\
        .reset_index()\
        .sort_values('count', ascending=False)\
        .drop_duplicates(subset=['Country', 'City'])\
        .drop('count', axis=1)
>>> print(grouped_df)
  Country              City Short name
1     USA          New-York         NY
0  Russia  Sankt-Petersburg        Spb

Move these two lines:

TextView txt = (TextView) findViewById(R.id.output);
txt.setText("Executed");

out of your AsyncTask's doInBackground method and put them in the onPostExecute method. Your AsyncTask should look something like this:

private class LongOperation extends AsyncTask<String, Void, String> {

    @Override
    protected String doInBackground(String... params) {
        try {
            Thread.sleep(5000); // no need for a loop
        } catch (InterruptedException e) {
            Log.e("LongOperation", "Interrupted", e);
            return "Interrupted";
        }
        return "Executed";
    }      

    @Override
    protected void onPostExecute(String result) {               
        TextView txt = (TextView) findViewById(R.id.output);
        txt.setText(result);
    }
}

In my case, I was downloading a library with sample code of keycloak implementation by mattorg from GITHUB: https://github.com/mattmorg55/Owin.Security.Keycloak/tree/dev/samples

The solution was quite easy, as I used .Net Framework 4.6.1, but the project begged me in the beginning to use 4.6.2. Although I downloaded it, it was first actively chosen, when restartet all instances of Visual Studion (or better close all instances). The project was manipulated to 4.6.1 (although I wished not and chose so).

So after I chose the configuration again to choose .Net Framework 4.6.1 the error vanished immediately.

ctypes module is part of the standard library, and therefore is more stable and widely available than swig, which always tended to give me problems.

With ctypes, you need to satisfy any compile time dependency on python, and your binding will work on any python that has ctypes, not just the one it was compiled against.

Suppose you have a simple C++ example class you want to talk to in a file called foo.cpp:

#include <iostream>

class Foo{
    public:
        void bar(){
            std::cout << "Hello" << std::endl;
        }
};

Since ctypes can only talk to C functions, you need to provide those declaring them as extern "C"

extern "C" {
    Foo* Foo_new(){ return new Foo(); }
    void Foo_bar(Foo* foo){ foo->bar(); }
}

Next you have to compile this to a shared library

g++ -c -fPIC foo.cpp -o foo.o
g++ -shared -Wl,-soname,libfoo.so -o libfoo.so  foo.o

And finally you have to write your python wrapper (e.g. in fooWrapper.py)

from ctypes import cdll
lib = cdll.LoadLibrary('./libfoo.so')

class Foo(object):
    def __init__(self):
        self.obj = lib.Foo_new()

    def bar(self):
        lib.Foo_bar(self.obj)

Once you have that you can call it like

f = Foo()
f.bar() #and you will see "Hello" on the screen

Candidate Key – A Candidate Key can be any column or a combination of columns that can qualify as unique key in database. There can be multiple Candidate Keys in one table. Each Candidate Key can qualify as Primary Key.

Primary Key – A Primary Key is a column or a combination of columns that uniquely identify a record. Only one Candidate Key can be Primary Key.

I had tried many different solutions. This was the only one that worked for me in that it was able to pick up on styles applied at class level and at style as directly attributed on the element. So a font set at css file level and one as a style attribute; it returned the correct font.

It is simple! (Sorry, can't find where I originally found it)

//-- html object
var element = htmlObject; //e.g document.getElementById
//-- or jquery object
var element = htmlObject[0]; //e.g $(selector)

var stylearray = document.defaultView.getComputedStyle(element, null);
var font = stylearray["font-family"]

Alternatively you can list all the style by cycling through the array

for (var key in stylearray) {
console.log(key + ': ' + stylearray[key];
}

The best to get rid of this is to keep activity reference when onAttach is called and use the activity reference wherever needed, for e.g.

@Override
public void onAttach(Context context) {
    super.onAttach(context);
    mContext = context;
}

@Override
public void onDetach() {
    super.onDetach();
    mContext = null;
}

Edited, since onAttach(Activity) is depreciated & now onAttach(Context) is being used

Declare @month as char(2)
Declare @date as char(2)
Declare @year as char(4)
declare @time as char(8)
declare @customdate as varchar(20)

set @month = MONTH(GetDate());
set @date = Day(GetDate());
set @year = year(GetDate());

set @customdate= @month+'/'+@date+'/'+@year+' '+ CONVERT(varchar(8), GETDATE(),108);
print(@customdate)

changed from your code :

private String toDate(long timestamp) {
    Date date = new Date (timestamp * 1000 -  24 * 60 * 60 * 1000);
   return new SimpleDateFormat("yyyy-MM-dd").format(date).toString();

}

but you do better using calendar.

I was having the same issue, where:

No marketplace entries found to handle build-helper-maven-plugin:1.8:add-source in Eclipse. Please see Help for more information.

and clicking the Window > Preferences > Maven > Discovery > open catalog button would report no connection.

Updating from 7u40 to 7u45 on Centos 6.4 and OSX fixes the issue.

update VersionedFields
set Value = replace(replace(value,'<iframe','<a>iframe'), '> </iframe>','</a>')

and you do it in a single pass.

In addition to @takemyoxygen's answer the convention of having a function name that ends in Async is that this function is truly asynchronous. I.e. it does not start a new thread and it doesn't simply call Task.Run. If that is all the code that is in your function, it will be better to remove it completely and simply have:

List<Item> list = await Task.Run(() => manager.GetList());

In my experience over the past few months, I've realized that the best way to achieve this is:

class App extends React.Component{
  constructor(){
   super();
   this.state = {
    serverResponse: ''
   }
  }
  componentDidMount(){
     this.getData();
  }
  async getData(){
   const res = await axios.get('url-to-get-the-data');
   const { data } = await res;
   this.setState({serverResponse: data})
 }
 render(){
  return(
     <div>
       {this.state.serverResponse}
     </div>
  );
 }
}

If you are trying to make post request on events such as click, then call getData() function on the event and replace the content of it like so:

async getData(username, password){
 const res = await axios.post('url-to-post-the-data', {
   username,
   password
 });
 ...
}

Furthermore, if you are making any request when the component is about to load then simply replace async getData() with async componentDidMount() and change the render function like so:

render(){
 return (
  <div>{this.state.serverResponse}</div>
 )
}

As per Where is Maven Installed on Ubuntu it will first create your settings.xml on /usr/share/maven2/, then you can copy to your home folder as jens mentioned

$ cp /usr/share/maven3/conf/settings.xml ~/.m2/settings.xml

I had some problems with this topic too. You have to make sure you define the packages in Spring boot runner class like this example below:

@SpringBootApplication
@EnableAutoConfiguration
@ComponentScan({"controller", "service"})
@EntityScan("entity")
@EnableJpaRepositories("repository")
public class Application {

    public static void main(String[] args){
        SpringApplication.run(Application.class, args);
    }

I hope this helps!

You can also edit the /etc/sysconfig/jenkins file to make any changes to the environment variables, etc. I simply added source /etc/profile to the end of the file. /etc/profile has all all of the proper PATH variables setup. When you do this, make sure you restart Jenkins

/etc/init.d/jenkins restart

We are running ZendServer CE which installs pear, phing, etc in a different path so this was helpful. Also, we don't get the LD_LIBRARY_PATH errors we used to get with Oracle client and Jenkins.

for /r %%v in (*.xls) do ssconvert "%%v" "%%vx"

a couple have people have asked me to explain this, so:

Part 1: for /r %%v in (*.xls)

This part returns an array of files in the current directory that have the xls extension. The %% may look a little curious. This is basically the special % character from command line as used in %PATH% or %TEMP%. To use it in a batch file we need to escape it like so: %%PATH%% or %%TEMP%%. In this case we are simply escaping the temporary variable v, which will hold our array of filenames.

We are using the /r switch to search for files recursively, so any matching files in child folders will also be located.

Part 2: do ssconvert "%%v" "%%vx"

This second part is what will get executed once per matching filename, so if the following files were present in the current folder:

c:\temp\mySheet.xls, c:\temp\mySheet_yesterday.xls, c:\temp\mySheet_20160902.xls

the following commands would be executed:

ssconvert "c:\temp\mySheet.xls" "c:\temp\mySheet.xlsx" ssconvert "c:\temp\mySheet_yesterday.xls" "c:\temp\mySheet_yesterday.xlsx" ssconvert "c:\temp\mySheet_20160902.xls" "c:\temp\mySheet_20160902.xlsx"

on my windows machine 8 machine running IIS 8 I can run the batch file just by putting the bats name and forgettig the path to it. Or by putting the bat in c:\windows\system32 don't ask me how it works but it does. LOL

$test=shell_exec("C:\windows\system32\cmd.exe /c $streamnumX.bat");

This seems to work fine for me:

$("#id")[0].outerHTML

This worked for me :

<?php
$url = parse_url($_SERVER['REQUEST_URI']);
parse_str($url['query'], $params);
?>

$params array contains the parameters passed after the ? character

My approach would be:

/// <summary>
/// Appends CSS Class seprated by a space character
/// </summary>
/// <param name="control">Target control</param>
/// <param name="cssClass">CSS class name to append</param>
public static void AppendCss(HtmlGenericControl control, string cssClass)
{
    // Ensure CSS class is definied
    if (string.IsNullOrEmpty(cssClass)) return;

    // Append CSS class
    if (string.IsNullOrEmpty(control.Attributes["class"]))
    {
        // Set our CSS Class as only one
        control.Attributes["class"] = cssClass;
    }
    else
    {
        // Append new CSS class with space as seprator
        control.Attributes["class"] += (" " + cssClass);
    }
}

Heap overflow should be blame (but not always) for corrupted double-linked list, malloc(): memory corruption, double free or corruption (!prev)-like glibc warnings.

It should be reproduced by the following code:

#include <vector>

using std::vector;


int main(int argc, const char *argv[])
{
    int *p = new int[3];
    vector<int> vec;
    vec.resize(100);
    p[6] = 1024;
    delete[] p;
    return 0;
}

if compiled using g++ (4.5.4):

$ ./heapoverflow

If you thought you might have written a bug like that, here is some hints to trace it out.

First, compile the code with debug flag(-g):

g++ -g foo.cpp

And then, run it using valgrind:

The answer by Nick Mitchinson is for Bootstrap version 2.

If you are using Bootstrap version 3, then forms have changed a bit. For bootstrap 3, use the following instead:

<div class="form-horizontal">
    <div class="form-group">
        <div class="col-md-6">
            <textarea class="form-control" rows="3" placeholder="What's up?" required></textarea>
        </div>
    </div>
</div>

Where, col-md-6 will target medium sized devices. You can add col-xs-6 etc to target smaller devices.

To set the use of scientific notation in your entire R session, you can use the scipen option. From the documentation (?options):

‘scipen’: integer.  A penalty to be applied when deciding to print
          numeric values in fixed or exponential notation.  Positive
          values bias towards fixed and negative towards scientific
          notation: fixed notation will be preferred unless it is more
          than ‘scipen’ digits wider.

So in essence this value determines how likely it is that scientific notation will be triggered. So to prevent scientific notation, simply use a large positive value like 999:

options(scipen=999)

I found the game library Allegro easy to use back in the day. Might be worth a look.

If you are using Node.js modules, __dirname and __filename don't exist.

From the Node.js documentation:

No require, exports, module.exports, __filename, __dirname

These CommonJS variables are not available in ES modules.

require can be imported into an ES module using module.createRequire().

Equivalents of __filename and __dirname can be created inside of each file via import.meta.url:

import { fileURLToPath } from 'url';
import { dirname } from 'path';

const __filename = fileURLToPath(import.meta.url);
const __dirname = dirname(__filename);

https://nodejs.org/docs/latest-v15.x/api/esm.html#esm_no_filename_or_dirname

You're looking for:

.is(':visible')

Although you should probably change your selector to use jQuery considering you're using it in other places anyway:

if($('#testElement').is(':visible')) {
    // Code
}

It is important to note that if any one of a target element's parent elements are hidden, then .is(':visible') on the child will return false (which makes sense).

jQuery 3

:visible has had a reputation for being quite a slow selector as it has to traverse up the DOM tree inspecting a bunch of elements. There's good news for jQuery 3, however, as this post explains (Ctrl + F for :visible):

Thanks to some detective work by Paul Irish at Google, we identified some cases where we could skip a bunch of extra work when custom selectors like :visible are used many times in the same document. That particular case is up to 17 times faster now!

Keep in mind that even with this improvement, selectors like :visible and :hidden can be expensive because they depend on the browser to determine whether elements are actually displaying on the page. That may require, in the worst case, a complete recalculation of CSS styles and page layout! While we don’t discourage their use in most cases, we recommend testing your pages to determine if these selectors are causing performance issues.

Expanding even further to your specific use case, there is a built in jQuery function called $.fadeToggle():

function toggleTestElement() {
    $('#testElement').fadeToggle('fast');
}

Example:

Model:

public class MyViewModel
{
    [Required]
    public string Foo { get; set; }
}

Controller:

public class HomeController : Controller
{
    public ActionResult Index()
    {
        return View(new MyViewModel());
    }

    [HttpPost]
    public ActionResult Index(MyViewModel model)
    {
        return Content("Thanks", "text/html");
    }
}

View:

@model AppName.Models.MyViewModel

<script src="@Url.Content("~/Scripts/jquery.unobtrusive-ajax.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/jquery.validate.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/jquery.validate.unobtrusive.js")" type="text/javascript"></script>

<div id="result"></div>

@using (Ajax.BeginForm(new AjaxOptions { UpdateTargetId = "result" }))
{
    @Html.EditorFor(x => x.Foo)
    @Html.ValidationMessageFor(x => x.Foo)
    <input type="submit" value="OK" />
}

and here's a better (in my perspective) example:

View:

@model AppName.Models.MyViewModel

<script src="@Url.Content("~/Scripts/jquery.validate.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/jquery.validate.unobtrusive.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/index.js")" type="text/javascript"></script>

<div id="result"></div>

@using (Html.BeginForm())
{
    @Html.EditorFor(x => x.Foo)
    @Html.ValidationMessageFor(x => x.Foo)
    <input type="submit" value="OK" />
}

index.js:

$(function () {
    $('form').submit(function () {
        if ($(this).valid()) {
            $.ajax({
                url: this.action,
                type: this.method,
                data: $(this).serialize(),
                success: function (result) {
                    $('#result').html(result);
                }
            });
        }
        return false;
    });
});

which can be further enhanced with the jQuery form plugin.

None of the top-voted answers worked for me, except when I unchecked "Use detected ADB location" as mentioned above by @???. Fortunately, in my case though, the message didn't show up, even when I turned it back on. In other words, the problem might be resolved by restarting "Use detected ADB location" :)

Colors are bit-encoded. If You want to change the Text color in C++ language There are many ways. In the console, you can change the properties of output.click this icon of the console and go to properties and change color.

The second way is calling the system colors.

#include <iostream>
#include <stdlib.h>

using namespace std;

int main()
{
    //Changing Font Colors of the System

    system("Color 7C");
    cout << "\t\t\t ****CEB Electricity Bill Calculator****\t\t\t " << endl;
    cout << "\t\t\t  ***                MENU           ***\t\t\t  " <<endl;

    return 0;

}

To access field or method of an object use dot .:

user = User()
print user.fullName

If a name of the field will be defined at run time, use buildin getattr function:

field_name = "fullName"
print getattr(user, field_name) # prints content of user.fullName

Your title and comments imply that you weren't looking for a sticky footer (stuck to the bottom of the window as content scrolls below it). I assume you were looking for a footer that would be forced to the bottom of the window if the content does not fill the window, and push down to the bottom of the content if the content exceeds the window boundary.

You can accomplish this with the following.

<style>
html,
body {
    margin:0;
    padding:0;
    height:100%;
}
#container {
    min-height:100%;
    position:relative;
}
#header {
    background:#ff0;
    padding:10px;
}
#body {
    padding:10px;
    padding-bottom:60px;   /* Height of the footer */
}
#footer {
    position:absolute;
    bottom:0;
    width:100%;
    height:60px;   /* Height of the footer */
    background:#6cf;
}
</style>

<div id="container">
    <div id="header">header</div>
    <div id="body">body</div>
    <div id="footer">footer</div>
</div>

To do a cross server query, check out the system stored procedure: sp_addlinkedserver in the help files.

Once the server is linked you can run a query against it.

Try

(n+10).toString(36)

chr = n=>(n+10).toString(36);_x000D_
_x000D_
for(i=0; i<26; i++) console.log(`${i} => ${ chr(i) }`);

The problem is with slashes: your variable contains them and the final command will be something like sed "s/string/path/to/something/g", containing way too many slashes.

Since sed can take any char as delimiter (without having to declare the new delimiter), you can try using another one that doesn't appear in your replacement string:

replacement="/my/path"
sed --expression "s@pattern@$replacement@"

Note that this is not bullet proof: if the replacement string later contains @ it will break for the same reason, and any backslash sequences like \1 will still be interpreted according to sed rules. Using | as a delimiter is also a nice option as it is similar in readability to /.

You can't declare an extern local method inside of a method, or any other method with an attribute. Move your DLL import into the class:

using System.Runtime.InteropServices;


public class WindowHandling
{
    [DllImport("User32.dll")]
    public static extern int SetForegroundWindow(IntPtr point);

    public void ActivateTargetApplication(string processName, List<string> barcodesList)
    {
        Process p = Process.Start("notepad++.exe");
        p.WaitForInputIdle();
        IntPtr h = p.MainWindowHandle;
        SetForegroundWindow(h);
        SendKeys.SendWait("k");
        IntPtr processFoundWindow = p.MainWindowHandle;
    }
}

This works well:

{{ app('request')->input('a') }}

Where a is the url parameter.

The line in the theme style works fine, yet that replaces the animation with a white screen. Especially on a slower phone - it is really annoying. So, if you want an instant transition - you could use this in the theme style:

<item name="android:windowAnimationStyle">@null</item>
<item name="android:windowDisablePreview">true</item>

Fetch the remote branch from the origin first.

git fetch origin remote_branch_name

Merge the remote branch to the local branch

git merge origin/remote_branch_name

When you first install maven, .m2 folder will not be present in C:\Users\ {user} path. To generate the folder you have to run any maven command e.g. mvn clean, mvn install etc. so that it searches for settings.xml in .m2 folder and when not found creates one.

So long story cur short, open cmd -> mvn install

It will show could not find any projects(Don't worry maven is working fine :P) now check your user folder.

P.S. If still not able to view .m2 folder try unhiding hidden items.

If your class is non-activity class, and creating an instance of it from the activiy, you can pass an instance of context via constructor of the later as follows:

class YourNonActivityClass{

// variable to hold context
private Context context;

//save the context recievied via constructor in a local variable

public YourNonActivityClass(Context context){
    this.context=context;
}

}

You can create instance of this class from the activity as follows:

new YourNonActivityClass(this);

you can use a generator:

li = [1,2,3,4,5,6]
len_li = len(li)
gen = (len_li-1-i for i in range(len_li))

finally:

for i in gen:
    print(li[i])

hope this help you.

A short version would be:

echo sh(script: 'ls -al', returnStdout: true).result

You can either do this on a PHP level or on a Javascript level. If you use Javascript, and/or JQuery, you can check and validate if all the checkboxes are checked with a selector...

Jquery also offers several validation libraries. Check out: http://jqueryvalidation.org/

The problem with using Javascript to validate is that it may be bypassed so it is wise to check on the server too.

Example using PHP and assuming you are calling a PO

<?php
    if( $_GET["BoxSelect"] )

are you sure that the id of the modal is "myModal"? if not then the call will not trigger it.

also - just from reading your post - you are triggering a function / validation with this button

<button type="button" id="creatNewAcount" class="btn btn-default" data-toggle="modal">Sign up</button>

and then if all is well - you want to trigger the modal. - if this is hte case - then you should remove the toggle from this button click. I presume you have an event handler tied to this click? you need the .modal("show") as a part of that function. not toggled from this button. also - is this id correct "creatNewAcount" as opposed to this spelling "createNewAccount"

<button type="button" id="creatNewAcount" class="btn btn-default" >Sign up</button>

If the XML have identities with same name in different levels there is a solution. You don´t have to ever submit a raw XML (this PHP SOAP object don´t allows send a RAW XML), so you have to always translate your XML to a array, like the example below:

$originalXML = "
<xml>
  <firstClient>
      <name>someone</name>
      <adress>R. 1001</adress>
  </firstClient>
  <secondClient>
      <name>another one</name>
      <adress></adress>
  </secondClient>
</xml>"

//Translate the XML above in a array, like PHP SOAP function requires
$myParams = array('firstClient' => array('name' => 'someone',
                                  'adress' => 'R. 1001'),
            'secondClient' => array('name' => 'another one',
                                  'adress' => ''));

$webService = new SoapClient($someURL);
$result = $webService->someWebServiceFunction($myParams);

or

$soapUrl = "http://privpakservices.schenker.nu/package/package_1.3/packageservices.asmx?op=SearchCollectionPoint";

$xml_post_string = '<?xml version="1.0" encoding="utf-8"?><soap12:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap12="http://www.w3.org/2003/05/soap-envelope"><soap12:Body><SearchCollectionPoint xmlns="http://privpakservices.schenker.nu/"><customerID>XXX</customerID><key>XXXXXX-XXXXXX</key><serviceID></serviceID><paramID>0</paramID><address>RiksvŠgen 5</address><postcode>59018</postcode><city>Mantorp</city><maxhits>10</maxhits></SearchCollectionPoint></soap12:Body></soap12:Envelope>';

$headers = array(
"POST /package/package_1.3/packageservices.asmx HTTP/1.1",
"Host: privpakservices.schenker.nu",
"Content-Type: application/soap+xml; charset=utf-8",
"Content-Length: ".strlen($xml_post_string)
); 

$url = $soapUrl;

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $xml_post_string);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

$response = curl_exec($ch); 
curl_close($ch);

$response1 = str_replace("<soap:Body>","",$response);
$response2 = str_replace("</soap:Body>","",$response1);

$parser = simplexml_load_string($response2);

If you want to initialize the list with N elements of some fixed value:

public List<T> InitList<T>(int count, T initValue)
{
  return Enumerable.Repeat(initValue, count).ToList();
}

A short example what is the difference between @Scope("singleton") (default) and @Scope("prototype"):

DAO class:

package com.example.demo;

public class Manager {
    private String name;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }
}

Configuration:

@Configuration
public class AppConfiguration {
    @Bean
    @Scope("singleton")
    public Manager getManager(){
        return new Manager();
    }
}

and MainApp:

@SpringBootApplication
public class DemoApplication {

    public static void main(String[] args) {
        SpringApplication.run(DemoApplication.class, args);
        AnnotationConfigApplicationContext context = new AnnotationConfigApplicationContext();
        context.scan("com.example.demo");
        context.refresh();

        Manager firstManager = context.getBean(Manager.class);
        firstManager.setName("Karol");

        Manager secondManager = context.getBean(Manager.class);
        System.out.println(secondManager.getName());
    }

}

In this example the result is: Karol even if we set this name only for firstManager object. It's because Spring IoC container created one instance of object. However when we change scope to @Scope("prototype") in Configuration class then result is: null because Spring IoC container creates a new bean instance of the object when request for that bean is made.

I put this in my makefile, right the next line after adb install ...

adb shell monkey -p `cat .identifier` -c android.intent.category.LAUNCHER 1

For this to work there must be a .identifier file with the app's bundle identifier in it, like com.company.ourfirstapp

No need to hunt activity name.

This may help Setting the header:

WebClient client = new WebClient();

string authInfo = this.credentials.UserName + ":" + this.credentials.Password;
authInfo = Convert.ToBase64String(Encoding.Default.GetBytes(authInfo));
client.Headers["Authorization"] = "Basic " + authInfo;

>>> l = [19, 1, 2, 3, 4, 20, 20]
>>> sorted(set(l))[-2]
19

Adding the tomcat server in the server runtime will do the job :

Project Properties-> Java Build Path-> Add Library -> Select "Server Runtime" from the list-> Next->Select "Apache Tomcat"-> Finish

I can't get that constructor to work either. This however seems to work:

# $temp = Get-ResourceFiles
$resourceFiles = New-Object System.Collections.ArrayList($null)
$resourceFiles.AddRange($temp)

You can also pass an integer in the constructor to set an initial capacity.

What do you mean when you say you want to enumerate the files? Why can't you just filter the wanted values into a fresh array?

Edit:

It seems that you can use the array constructor like this:

$resourceFiles = New-Object System.Collections.ArrayList(,$someArray)

Note the comma. I believe what is happening is that when you call a .NET method, you always pass parameters as an array. PowerShell unpacks that array and passes it to the method as separate parameters. In this case, we don't want PowerShell to unpack the array; we want to pass the array as a single unit. Now, the comma operator creates arrays. So PowerShell unpacks the array, then we create the array again with the comma operator. I think that is what is going on.

Hi Guys you cant convert directly string to bigdecimal

you need to first convert it into long after that u will convert big decimal

String currency = "135.69"; 
Long rate1=Long.valueOf((currency ));            
System.out.println(BigDecimal.valueOf(rate1));

1. Open your favorite text editor
2. Create a new file named whatever.h
3. Put your function prototypes in it

DONE.

Example whatever.h

#ifndef WHATEVER_H_INCLUDED
#define WHATEVER_H_INCLUDED
int f(int a);
#endif

Note: include guards (preprocessor commands) added thanks to luke. They avoid including the same header file twice in the same compilation. Another possibility (also mentioned on the comments) is to add #pragma once but it is not guaranteed to be supported on every compiler.

Example whatever.c

#include "whatever.h"

int f(int a) { return a + 1; }

And then you can include "whatever.h" into any other .c file, and link it with whatever.c's object file.

Like this:

sample.c

#include "whatever.h"

int main(int argc, char **argv)
{
    printf("%d\n", f(2)); /* prints 3 */
    return 0;
}

To compile it (if you use GCC):

$ gcc -c whatever.c -o whatever.o
$ gcc -c sample.c -o sample.o

To link the files to create an executable file:

$ gcc sample.o whatever.o -o sample

You can test sample:

$ ./sample
3
$

I spent too much time to figure out this problem for me.

I had PHP version 5.5 and I needed to upgrade to 5.6.

In versions < 5.6 Guzzle will use it's own cacert.pem file, but in higher versions of PHP it will use system's cacert.pem file.

I also downloaded file from here https://curl.haxx.se/docs/caextract.html and set it in php.ini.

Answer found in Guzzles StreamHandler.php file https://github.com/guzzle/guzzle/blob/0773d442aa96baf19d7195f14ba6e9c2da11f8ed/src/Handler/StreamHandler.php#L437

        // PHP 5.6 or greater will find the system cert by default. When
        // < 5.6, use the Guzzle bundled cacert.

There's a section of @media print code in the css file (Bootstrap 3.3.1 [UPDATE:] to 3.3.5), this strips virtually all the styling, so you get fairly bland print-outs even when it is working.

For now I've had to resort to stripping out the @media print section from bootstrap.css - which I'm really not happy about but my users want direct screen-grabs so this'll have to do for now. If anyone knows how to suppress it without changes to the bootstrap files I'd be very interested.

Here's the 'offending' code block, starts at line #192:

@media print {

  *:before,enter code here

    content: "";

To answer the question:

What is the fastest way to stream live video using JavaScript? Is WebSockets over TCP a fast enough protocol to stream a video of, say, 30fps?

Yes, Websocket can be used to transmit over 30 fps and even 60 fps.

The main issue with Websocket is that it is low-level and you have to deal with may other issues than just transmitting video chunks. All in all it's a great transport for video and also audio.

Do not forget to run the command php artisan config:clear after you have made the changes to the .env file. Done this again php artisan env, which will return the correct version.

Ref: http://docs.python.org/howto/unicode

Reading Unicode from a file is therefore simple:

import codecs
with codecs.open('unicode.rst', encoding='utf-8') as f:
    for line in f:
        print repr(line)

It's also possible to open files in update mode, allowing both reading and writing:

with codecs.open('test', encoding='utf-8', mode='w+') as f:
    f.write(u'\u4500 blah blah blah\n')
    f.seek(0)
    print repr(f.readline()[:1])

EDIT: I'm assuming that your intended goal is just to be able to read the file properly into a string in Python. If you're trying to convert to an ASCII string from Unicode, then there's really no direct way to do so, since the Unicode characters won't necessarily exist in ASCII.

If you're trying to convert to an ASCII string, try one of the following:

1. Replace the specific unicode chars with ASCII equivalents, if you are only looking to handle a few special cases such as this particular example

2. Use the unicodedata module's normalize() and the string.encode() method to convert as best you can to the next closest ASCII equivalent (Ref https://web.archive.org/web/20090228203858/http://techxplorer.com/2006/07/18/converting-unicode-to-ascii-using-python):

   >>> teststr
   u'I don\xe2\x80\x98t like this'
   >>> unicodedata.normalize('NFKD', teststr).encode('ascii', 'ignore')
   'I donat like this'
   

See https://polarssl.org/kb/cryptography/asn1-key-structures-in-der-and-pem (search the page for "BEGIN RSA PRIVATE KEY") (archive link for posterity, just in case).

BEGIN RSA PRIVATE KEY is PKCS#1 and is just an RSA key. It is essentially just the key object from PKCS#8, but without the version or algorithm identifier in front. BEGIN PRIVATE KEY is PKCS#8 and indicates that the key type is included in the key data itself. From the link:

The unencrypted PKCS#8 encoded data starts and ends with the tags:

-----BEGIN PRIVATE KEY-----
BASE64 ENCODED DATA
-----END PRIVATE KEY-----

Within the base64 encoded data the following DER structure is present:

PrivateKeyInfo ::= SEQUENCE {
  version         Version,
  algorithm       AlgorithmIdentifier,
  PrivateKey      BIT STRING
}

AlgorithmIdentifier ::= SEQUENCE {
  algorithm       OBJECT IDENTIFIER,
  parameters      ANY DEFINED BY algorithm OPTIONAL
}

So for an RSA private key, the OID is 1.2.840.113549.1.1.1 and there is a RSAPrivateKey as the PrivateKey key data bitstring.

As opposed to BEGIN RSA PRIVATE KEY, which always specifies an RSA key and therefore doesn't include a key type OID. BEGIN RSA PRIVATE KEY is PKCS#1:

RSA Private Key file (PKCS#1)

The RSA private key PEM file is specific for RSA keys.

It starts and ends with the tags:

-----BEGIN RSA PRIVATE KEY-----
BASE64 ENCODED DATA
-----END RSA PRIVATE KEY-----

Within the base64 encoded data the following DER structure is present:

RSAPrivateKey ::= SEQUENCE {
  version           Version,
  modulus           INTEGER,  -- n
  publicExponent    INTEGER,  -- e
  privateExponent   INTEGER,  -- d
  prime1            INTEGER,  -- p
  prime2            INTEGER,  -- q
  exponent1         INTEGER,  -- d mod (p-1)
  exponent2         INTEGER,  -- d mod (q-1)
  coefficient       INTEGER,  -- (inverse of q) mod p
  otherPrimeInfos   OtherPrimeInfos OPTIONAL
}

Adding bootstrap current version 4 to angular:

1/ First you have to install those:

npm install jquery --save
npm install popper.js --save
npm install bootstrap --save

2/ Then add the needed script files to scripts in angular.json:

"scripts": [
  "node_modules/jquery/dist/jquery.slim.js",
  "node_modules/popper.js/dist/umd/popper.js",
  "node_modules/bootstrap/dist/js/bootstrap.js"
],

3/Finally add the Bootstrap CSS to the styles array in angular.json:

"styles": [
  "node_modules/bootstrap/dist/css/bootstrap.css",
  "src/styles.css"
],`

check this link

As per comments, First you need to install an instance of SQL Server if you don't already have one - https://msdn.microsoft.com/en-us/library/ms143219.aspx

Once this is installed you must connect to this instance (server) and then you can create a database here - https://msdn.microsoft.com/en-US/library/ms186312.aspx

Using url-loader, described here (SurviveJS - Loading Images), you can then use in your code :

import LogoImg from 'YOUR_PATH/logo.png';

and

<img src={LogoImg}/>

Edit: a precision, images are inlined in the js archive with this technique. It can be worthy for small images, but use the technique wisely.

If you want to try with java code. Here you go -

    final LayoutParams params = new LayoutParams(LayoutParams.WRAP_CONTENT, 
                                             LayoutParams.WRAP_CONTENT);
    yourView.setLayoutParams(params);
    params.gravity = Gravity.BOTTOM; // set gravity

The following configs works on Cent OS 6 or earlier

As stated above first have to disable selinux.

Step 1 nano /etc/sysconfig/selinux

Make sure the file has this configurations

SELINUX=disabled

SELINUXTYPE=targeted

Then restart the system

Step 2

iptables -A INPUT -m state --state NEW -p tcp --dport 8080 -j ACCEPT

Step 3

sudo service iptables save

For Cent OS 7

step 1

firewall-cmd --zone=public --permanent --add-port=8080/tcp

Step 2

firewall-cmd --reload

(A || B) && !(A && B)

The first part is A OR B, which is the Inclusive OR; the second part is, NOT A AND B. Together you get A or B, but not both A and B.

This will provide the XOR proved in the truth table below.

|-----|-----|-----------|
|  A  |  B  |  A XOR B  |
|-----|-----|-----------|
|  T  |  T  |   False   |
|-----|-----|-----------|
|  T  |  F  |   True    |
|-----|-----|-----------|
|  F  |  T  |   True    |
|-----|-----|-----------|
|  F  |  F  |   False   |
|-----|-----|-----------|

If your list of values is to be hard-coded in the script, it's fairly simple to test using case. Here's a short example, which you can adapt to your requirements:

for item in $list
do
    case "$x" in
      item1|item2)
        echo "In the list"
        ;;
      not_an_item)
        echo "Error" >&2
        exit 1
        ;;
    esac
done

If the list is an array variable at runtime, one of the other answers is probably a better fit.

To set permanent PuTTY session parameters do:

1. Create sessions in PuTTY. Name it as "MyskinPROD"

2. Configure the path for this session to point to "C:\dir\&Y&M&D&T_&H_putty.log".

3. Create a Windows "Shortcut" to C:...\Putty.exe.

4. Open "Shortcut" Properties and append "Target" line with parameters as shown below:

   "C:\Program Files (x86)\UTL\putty.exe" -ssh -load MyskinPROD user@ServerIP -pw password
   

Now, your PuTTY shortcut will bring in the "MyskinPROD" configuration every time you open the shortcut.

As well as pointers and references to incomplete types, you can also declare function prototypes that specify parameters and/or return values that are incomplete types. However, you cannot define a function having a parameter or return type that is incomplete, unless it is a pointer or reference.

Examples:

struct X;              // Forward declaration of X

void f1(X* px) {}      // Legal: can always use a pointer
void f2(X&  x) {}      // Legal: can always use a reference
X f3(int);             // Legal: return value in function prototype
void f4(X);            // Legal: parameter in function prototype
void f5(X) {}          // ILLEGAL: *definitions* require complete types

I'm probably spoiled by abundant ram, but 15 M is not huge. Reading into memory with readlines() is what I usually do with files of this size. Accessing a line after that is trivial.

This command will show also if the file is hidden adb shell ls -laR | grep filename

The Solution is to 'break' the relationship between the objects, and then try to delete again. The answer is in your log:

(remove deleted object from associations): [com.xeno.advertisingsuite.web.domain.PlaylistadMap#6]

Explain: what?(remove association) Where?[PlaylistadMap object with id#6]

The problem is in this method:

  public static byte[] encrypt(String toEncrypt) throws Exception{

This is the method signature which pretty much says:

• what the method name is: encrypt
• what parameter it receives: a String named toEncrypt
• its access modifier: public static
• and if it may or not throw an exception when invoked.

In this case the method signature says that when invoked this method "could" potentially throw an exception of type "Exception".

    ....
    concatURL = padString(concatURL, ' ', 16);
    byte[] encrypted = encrypt(concatURL); <-- HERE!!!!!
    String encryptedString = bytesToHex(encrypted);
    content.removeAll();
    ......

So the compilers is saying: Either you surround that with a try/catch construct or you declare the method ( where is being used ) to throw "Exception" it self.

The real problem is the "encrypt" method definition. No method should ever return "Exception", because it is too generic and may hide some other kinds of exception better is to have an specific exception.

Try this:

public static byte[] encrypt(String toEncrypt) {
    try{
      String plaintext = toEncrypt;
      String key = "01234567890abcde";
      String iv = "fedcba9876543210";

      SecretKeySpec keyspec = new SecretKeySpec(key.getBytes(), "AES");
      IvParameterSpec ivspec = new IvParameterSpec(iv.getBytes());

      Cipher cipher = Cipher.getInstance("AES/CBC/NoPadding");
      cipher.init(Cipher.ENCRYPT_MODE,keyspec,ivspec);
      byte[] encrypted = cipher.doFinal(toEncrypt.getBytes());

      return encrypted;
    } catch ( NoSuchAlgorithmException nsae ) { 
        // What can you do if the algorithm doesn't exists??
        // this usually won't happen because you would test 
        // your code before shipping. 
        // So in this case is ok to transform to another kind 
        throw new IllegalStateException( nsae );
    } catch ( NoSuchPaddingException nspe ) { 
       // What can you do when there is no such padding ( whatever that means ) ??
       // I guess not much, in either case you won't be able to encrypt the given string
        throw new IllegalStateException( nsae );
    }
    // line 109 won't say it needs a return anymore.
  }

Basically in this particular case you should make sure the cryptography package is available in the system.

Java needs an extension for the cryptography package, so, the exceptions are declared as "checked" exceptions. For you to handle when they are not present.

In this small program you cannot do anything if the cryptography package is not available, so you check that at "development" time. If those exceptions are thrown when your program is running is because you did something wrong in "development" thus a RuntimeException subclass is more appropriate.

The last line don't need a return statement anymore, in the first version you were catching the exception and doing nothing with it, that's wrong.

try { 
    // risky code ... 
} catch( Exception e ) { 
    // a bomb has just exploited
    // you should NOT ignore it 
} 

// The code continues here, but what should it do???

If the code is to fail, it is better to Fail fast

Here are some related answers:

• Catching Exceptions in Java

• When to choose checked and unchecked exceptions

• Why don’t you have to explicitly declare that you might throw some built in exceptions in Java?

• Exception other than RuntimeException

Thanks all for your help! Finally I used JQuery/AJAX as you suggested, passing the parameter using model.

So, in JS:

$('#divPoints').load('/Schedule/UpdatePoints', UpdatePointsAction);
var points= $('#newpoints').val();
$element.find('PointsDiv').html("You have" + points+ " points");

In Controller:

var model = _newPoints;
return PartialView(model);

In View

<div id="divPoints"></div>
@Html.Hidden("newpoints", Model)

The dig utility is pretty convenient to use. The order of the arguments don't really matter.I'll show you some easy examples.
To get all root name servers use

# dig

To get a TXT record of a specific host use

# dig example.com txt
# dig host.example.com txt

To query a specific name server just add @nameserver.tld

# dig host.example.com txt @a.iana-servers.net

The SPF RFC4408 says that SPF records can be stored as SPF or TXT. However nearly all use only TXT records at the moment. So you are pretty safe if you only fetch TXT records.

I made a SPF checker for visualising the SPF records of a domain. It might help you to understand SPF records better. You can find it here: http://spf.myisp.ch

Another option is the janitor package:

df <- remove_empty_cols(df)

Instead of hard-coded converters, how about CSV support for Jackson (JSON processor): https://github.com/FasterXML/jackson-dataformat-csv. So core Jackson can read JSON in as POJOs, Maps, JsonNode, almost anything. And CSV support can do the same with CSV. Combine the two and it's very powerful but simple converter between multiple formats (there are backends for XML, YAML already, and more being added).

An article that shows how to do this can be found here.

we have to create your own docker volume mapped with the host directory before we mention in the docker-compose.yml as external

1.Create volume named share

docker volume create --driver local \
--opt type=none \
--opt device=/home/mukundhan/share \
--opt o=bind share

2.Use it in your docker-compose

version: "3"

volumes:
  share:
    external: true

services:
  workstation:
    container_name: "workstation"
    image: "ubuntu"
    stdin_open: true
    tty: true
    volumes:
      - share:/share:consistent
      - ./source:/source:consistent
    working_dir: /source
    ipc: host
    privileged: true
    shm_size: '2gb'
  db:
    container_name: "db"
    image: "ubuntu"
    stdin_open: true
    tty: true
    volumes:
      - share:/share:consistent
    working_dir: /source
    ipc: host

This way we can share the same directory with many services running in different containers

I had the same issue. I think it was a deadlock issue with SQL. You can just force close the SQL process from Task Manager. If that didn't fix it, just restart your computer. You don't need to drop the table and reload the data.

Lists typically preserve the order in which items are added. Do you definitely need a list, or would a sorted set (e.g. TreeSet<E>) be okay for you? Basically, do you need to need to preserve duplicates?

Problem is system is not able to find the file tools.jar

So first check that the file is there in the JDK installation of the directory.

Make the below entry in POM.xml as rightly pointed by others

<dependency>
<groupId>com.sun</groupId>
<artifactId>tools</artifactId>
<version>1.6</version>
<scope>system</scope>
<systemPath>C:\Program Files\Java\jdk1.8.0_241\lib\tools.jar</systemPath>
</dependency> 

then Follow the below steps also to remove the problem

1) Right Click on your project

2) Click on Build path

As per the below image, select the workspace default JRE and click on finish.

TL;DR. You can get around this by expressing your queries as MyModel::query()->find(10); instead of MyModel::find(10);.

To the best of my knowledge, starting PhpStorm 2017.2 code inspection fails for methods such as MyModel::where(), MyModel::find(), etc (check this thread). This could get quite annoying, when you try let's say to use PhpStorm's Git integration before committing your code, PhpStorm won't stop complaining about these static method call warnings.

One elegant way (IMOO) to get around this is to explicitly call ::query() wherever it makes sense to. This will let you benefit from a free auto-completion and a nice query formatting.

Examples

Snippet where inspection complains about static method calls

$myModel = MyModel::find(10); // static call complaint

// another poorly formatted query with code inspection complaints
$myFilteredModels = MyModel::where('is_beautiful', true)
    ->where('is_not_smart', false)
    ->get();

Well formatted code with no complaints

$myModel = MyModel::query()->find(10);

// a nicely formatted query with no complaints
$myFilteredModels = MyModel::query()
    ->where('is_beautiful', true)
    ->where('is_not_smart', false)
    ->get();

Can use generics to combine arrays. Following code can easily be expanded to three arrays. This way you never need to duplicate code for different type of arrays. Some of the above answers seem overly complex to me.

private static T[] CombineTwoArrays<T>(T[] a1, T[] a2)
    {
        T[] arrayCombined = new T[a1.Length + a2.Length];
        Array.Copy(a1, 0, arrayCombined, 0, a1.Length);
        Array.Copy(a2, 0, arrayCombined, a1.Length, a2.Length);
        return arrayCombined;
    }

Use a parameter array with the params modifier:

public static int AddUp(params int[] values)
{
    int sum = 0;
    foreach (int value in values)
    {
        sum += value;
    }
    return sum;
}

If you want to make sure there's at least one value (rather than a possibly empty array) then specify that separately:

public static int AddUp(int firstValue, params int[] values)

(Set sum to firstValue to start with in the implementation.)

Note that you should also check the array reference for nullity in the normal way. Within the method, the parameter is a perfectly ordinary array. The parameter array modifier only makes a difference when you call the method. Basically the compiler turns:

int x = AddUp(4, 5, 6);

into something like:

int[] tmp = new int[] { 4, 5, 6 };
int x = AddUp(tmp);

You can call it with a perfectly normal array though - so the latter syntax is valid in source code as well.

Let's start with the problems these tools want to solve:

My system package manager don't have the Python versions I wanted or I want to install multiple Python versions side by side, Python 3.9.0 and Python 3.9.1, Python 3.5.3, etc

Then use pyenv.

I want to install and run multiple applications with different, conflicting dependencies.

Then use virtualenv or venv. These are almost completely interchangeable, the difference being that virtualenv supports older python versions and has a few more minor unique features, while venv is in the standard library.

I'm developing an /application/ and need to manage my dependencies, and manage the dependency resolution of the dependencies of my project.

Then use pipenv or poetry.

I'm developing a /library/ or a /package/ and want to specify the dependencies that my library users need to install

Then use setuptools.

I used virtualenv, but I don't like virtualenv folders being scattered around various project folders. I want a centralised management of the environments and some simple project management

Then use virtualenvwrapper. Variant: pyenv-virtualenvwrapper if you also use pyenv.

Not recommended

• pyvenv. This is deprecated, use venv or virtualenv instead. Not to be confused with pipenv or pyenv.

"Unicode" is unfortunately used in various different ways, depending on the context. Its most correct use (IMO) is as a coded character set - i.e. a set of characters and a mapping between the characters and integer code points representing them.

UTF-8 is a character encoding - a way of converting from sequences of bytes to sequences of characters and vice versa. It covers the whole of the Unicode character set. ASCII is encoded as a single byte per character, and other characters take more bytes depending on their exact code point (up to 4 bytes for all currently defined code points, i.e. up to U-0010FFFF, and indeed 4 bytes could cope with up to U-001FFFFF).

When "Unicode" is used as the name of a character encoding (e.g. as the .NET Encoding.Unicode property) it usually means UTF-16, which encodes most common characters as two bytes. Some platforms (notably .NET and Java) use UTF-16 as their "native" character encoding. This leads to hairy problems if you need to worry about characters which can't be encoded in a single UTF-16 value (they're encoded as "surrogate pairs") - but most developers never worry about this, IME.

Some references on Unicode:

• The Unicode consortium web site and in particular the tutorials section
• Joel's article
• My own article (.NET-oriented)

How about something like:

\documentclass{article}

\usepackage{amssymb,amsmath}

\begin{document}

\begin{equation}\label{A_Label}
  \begin{split}
    w^T x_i + b \geqslant 1-\xi_i \text{ if } y_i &= 1, \\
    w^T x_i + b \leqslant -1+\xi_i \text{ if } y_i &= -1
  \end{split}
\end{equation}

\end{document}

which produces:

For arrays containing only strings or numbers you can do something with sorting, as per some of the other answers. For the general case of arrays of arbitrary objects I don't think you can avoid doing it the long way. The following will give you the intersection of any number of arrays provided as parameters to arrayIntersection:

var arrayContains = Array.prototype.indexOf ?
    function(arr, val) {
        return arr.indexOf(val) > -1;
    } :
    function(arr, val) {
        var i = arr.length;
        while (i--) {
            if (arr[i] === val) {
                return true;
            }
        }
        return false;
    };

function arrayIntersection() {
    var val, arrayCount, firstArray, i, j, intersection = [], missing;
    var arrays = Array.prototype.slice.call(arguments); // Convert arguments into a real array

    // Search for common values
    firstArray = arrays.pop();
    if (firstArray) {
        j = firstArray.length;
        arrayCount = arrays.length;
        while (j--) {
            val = firstArray[j];
            missing = false;

            // Check val is present in each remaining array 
            i = arrayCount;
            while (!missing && i--) {
                if ( !arrayContains(arrays[i], val) ) {
                    missing = true;
                }
            }
            if (!missing) {
                intersection.push(val);
            }
        }
    }
    return intersection;
}

arrayIntersection( [1, 2, 3, "a"], [1, "a", 2], ["a", 1] ); // Gives [1, "a"]; 

I have used similar code for downloading logs from servers. I debug my code and discovered that implementation of URLConnection which is returned is sun.net.www.protocol.http.HttpURLConnection.

Abstract class java.net.URLConnection have two attributes connectTimeout and readTimeout and setters are in abstract class. Believe or not implementation sun.net.www.protocol.http.HttpURLConnection have same attributes connectTimeout and readTimeout without setters and attributes from implementation class are used in getInputStream method. So there is no use of setting connectTimeout and readTimeout because they are never used in getInputStream method. In my opinion this is bug in sun.net.www.protocol.http.HttpURLConnection implementation.

My solution for this was to use HttpClient and Get request.

It's also cleaner to use @JoinTable when an Entity could be the child in several parent/child relationships with different types of parents. To follow up with Behrang's example, imagine a Task can be the child of Project, Person, Department, Study, and Process.

Should the task table have 5 nullable foreign key fields? I think not...

Obviously there is no periodic checking of Scope whether there is any change in the Objects attached to it. Not all the objects attached to scope are watched . Scope prototypically maintains a $$watchers . Scope only iterates through this $$watchers when $digest is called .

Angular adds a watcher to the $$watchers for each of these

1. {{expression}} — In your templates (and anywhere else where there’s an expression) or when we define ng-model.
   
2. $scope.$watch(‘expression/function’) — In your JavaScript we can just attach a scope object for angular to watch.

$watch function takes in three parameters:

1. First one is a watcher function which just returns the object or we can just add an expression.
   

2. Second one is a listener function which will be called when there is a change in the object. All the things like DOM changes will be implemented in this function.
   

3. The third being an optional parameter which takes in a boolean . If its true , angular deep watches the object & if its false Angular just does a reference watching on the object. Rough Implementation of $watch looks like this

Scope.prototype.$watch = function(watchFn, listenerFn) {
   var watcher = {
       watchFn: watchFn,
       listenerFn: listenerFn || function() { },
       last: initWatchVal  // initWatchVal is typically undefined
   };
   this.$$watchers.push(watcher); // pushing the Watcher Object to Watchers  
};

There is an interesting thing in Angular called Digest Cycle. The $digest cycle starts as a result of a call to $scope.$digest(). Assume that you change a $scope model in a handler function through the ng-click directive. In that case AngularJS automatically triggers a $digest cycle by calling $digest().In addition to ng-click, there are several other built-in directives/services that let you change models (e.g. ng-model, $timeout, etc) and automatically trigger a $digest cycle. The rough implementation of $digest looks like this.

Scope.prototype.$digest = function() {
      var dirty;
      do {
          dirty = this.$$digestOnce();
      } while (dirty);
}
Scope.prototype.$$digestOnce = function() {
   var self = this;
   var newValue, oldValue, dirty;
   _.forEach(this.$$watchers, function(watcher) {
          newValue = watcher.watchFn(self);
          oldValue = watcher.last;   // It just remembers the last value for dirty checking
          if (newValue !== oldValue) { //Dirty checking of References 
   // For Deep checking the object , code of Value     
   // based checking of Object should be implemented here
             watcher.last = newValue;
             watcher.listenerFn(newValue,
                  (oldValue === initWatchVal ? newValue : oldValue),
                   self);
          dirty = true;
          }
     });
   return dirty;
 };

If we use JavaScript’s setTimeout() function to update a scope model, Angular has no way of knowing what you might change. In this case it’s our responsibility to call $apply() manually, which triggers a $digest cycle. Similarly, if you have a directive that sets up a DOM event listener and changes some models inside the handler function, you need to call $apply() to ensure the changes take effect. The big idea of $apply is that we can execute some code that isn't aware of Angular, that code may still change things on the scope. If we wrap that code in $apply , it will take care of calling $digest(). Rough implementation of $apply().

Scope.prototype.$apply = function(expr) {
       try {
         return this.$eval(expr); //Evaluating code in the context of Scope
       } finally {
         this.$digest();
       }
};

The following will be able to process very large files quickly.

$file = New-Object System.IO.StreamReader -Arg "file1.txt"
$outstream = [System.IO.StreamWriter] "file2.txt"
$count = 0 

while ($line = $file.ReadLine()) {
      $count += 1
      $s = $line -replace "`n", "`r`n"
      $outstream.WriteLine($s)
  }

$file.close()
$outstream.close()

Write-Host ([string] $count + ' lines have been processed.')

I solve the problem the following way (MySQL only)

$q = $dbh->prepare("DESCRIBE tablename");
$q->execute();
$table_fields = $q->fetchAll(PDO::FETCH_COLUMN);

Like others, I've found that the plugin can be made (via JS) to shrink when the container shrinks, but afterwards will not grow when it expands.

The issue is that the original FB.XFBML.parse() creates a set of child nodes with fixed styles in the document tree, and later invocations will not properly clean out the old nodes. If you do it yourself in your code, all is well.

Facebook HTML (I merely added ID elements to what Facebook provided, to avoid any selector accidents):

<div id="divFacebookFeed" class="fb-page" data-href="..." ...>
    <blockquote id="bqNoFeed" cite="(your URL)" class="fb-xfbml-parse-ignore">
        <a href="(your URL)">Your Site</a>
    </blockquote>
</div>

...JQuery code to resize the widget to 500px and preserve the inner fallback element:

var bq = $('#bqNoFeed').detach();
var fbdiv = $('#divFacebookFeed');

fbdiv.attr('data-width', 500);
fbdiv.empty();
fbdiv.append(bq);
FB.XFBML.parse();

You can create simple float-based forms without having to lose your liquid layout. For example:

<style type="text/css">
    .row { clear: left; padding: 6px; }
    .row label { float: left; width: 10em; }
    .row .field { display: block; margin-left: 10em; }
    .row .field input, .row .field select {
        width: 100%;
        box-sizing: border-box;
        -moz-box-sizing: border-box; -webkit-box-sizing: border-box; -khtml-box-sizing: border-box;
    }
</style>

<div class="row">
    <label for="f-firstname">First name</label>
    <span class="field"><input name="firstname" id="f-firstname" value="Bob" /></span>
</div>
<div class="row">
    <label for="f-state">State</label>
    <span class="field"><select name="state" id="f-state">
        <option value="NY">NY</option>
    </select></span>
</div>

This does tend to break down, though, when you have complex form layouts where there's a grid of multiple fixed and flexible width columns. At that point you have to decide whether to stick with divs and abandon liquid layout in favour of just dropping everything into fixed pixel positions, or let tables do it.

For me personally, liquid layout is a more important usability feature than the exact elements used to lay out the form, so I usually go for tables.

That is not possible bro, Laravel assumes everything is in public folder.

So my suggestion is:

1. Go to the public folder.
2. Create a folder, preferably named css.
3. Create the folder for the respective views to make things organized.
4. Put the respective css inside of those folders, that would be easier for you.

Or

If you really insist to put css inside of views folder, you could try creating Symlink (you're mac so it's ok, but for windows, this will only work for Vista, Server 2008 or greater) from your css folder directory to the public folder and you can use {{HTML::style('your_view_folder/myStyle.css')}} inside of your view files, here's a code for your convenience, in the code you posted, put these before the return View::make():

$css_file = 'myStyle.css';
$folder_name = 'your_view_folder';
$view_path = app_path() . '/views/' . $folder_name . '/' . $css_file;
$public_css_path = public_path() . '/' . $folder_name;
if(file_exists($public_css_path)) exec('rm -rf ' . $public_css_path);
exec('mkdir ' . $public_css_path);
exec('ln -s ' . $view_path .' ' . $public_css_path . '/' . $css_file);

If you really want to try doing your idea, try this:

<link rel="stylesheet" href="<?php echo app_path() . 'views/your_view_folder/myStyle.css'?>" type="text/css">

But it won't work even if the file directory is correct because Laravel won't do that for security purposes, Laravel loves you that much.

Sidenote: With modern Git (>= 1.6.6), you are able to use just

git checkout test

(note that it is 'test' not 'origin/test') to perform magical DWIM-mery and create local branch 'test' for you, for which upstream would be remote-tracking branch 'origin/test'.

The * (no branch) in git branch output means that you are on unnamed branch, in so called "detached HEAD" state (HEAD points directly to commit, and is not symbolic reference to some local branch). If you made some commits on this unnamed branch, you can always create local branch off current commit:

git checkout -b test HEAD

** EDIT (by editor not author) **

I found a comment buried below which seems to modernize this answer:

@Dennis: git checkout <non-branch>, for example git checkout origin/test results in detached HEAD / unnamed branch, while git checkout test or git checkout -b test origin/test results in local branch test (with remote-tracking branch origin/test as upstream) – Jakub Narebski Jan 9 '14 at 8:17

emphasis on git checkout origin/test

My DBA asked me when I asked about the best way to store GUIDs for my objects why I needed to store 16 bytes when I could do the same thing in 4 bytes with an Integer. Since he put that challenge out there to me I thought now was a good time to mention it. That being said...

You can store a guid as a CHAR(16) binary if you want to make the most optimal use of storage space.

I would use two classes. Keep your test class and add a second class called testhover which you only add to those you want to hover - alongside the test class. This isn't directly what you asked but without more context it feels like the best solution and is possibly the cleanest and simplest way of doing it.

Example:

.test {  border: 0px; }_x000D_
.testhover:hover {  border: 1px solid red; }

<div class="test"> blah </div>_x000D_
<div class="test"> blah </div>_x000D_
<div class="test testhover"> blah </div>

});

// resize the window by passed w,h parameter
sampleWnd.resize(screen.width, screen.height);

Drop the public $bar; declaration and it should work as expected.

Well it's 2016 and there is still no easy way to do a combo ... sure we have datalist but without safari/ios support it's not really usable. At least we have ES6 .. below is an attempt at a combo class that wraps a div or span, turning it into a combo by putting an input box on top of select and binding the relevant events.

see the code at: https://github.com/kofifus/Combo

(the code relies on the class pattern from https://github.com/kofifus/New)

Creating a combo is easy ! just pass a div to it's constructor:

let mycombo=Combo.New(document.getElementById('myCombo'));_x000D_
mycombo.options(['first', 'second', 'third']);_x000D_
_x000D_
mycombo.onchange=function(e, combo) {_x000D_
  let val=combo.value;_x000D_
  // let val=this.value; // same as above_x000D_
  alert(val);_x000D_
 }

<script src="https://rawgit.com/kofifus/New/master/new.min.js"></script>_x000D_
<script src="https://rawgit.com/kofifus/Combo/master/combo.min.js"></script>_x000D_
_x000D_
<div id="myCombo" style="width:100px;height:20px;"></div>

Shouldn't it simply be:

<button ng-click="clickingCallback()">Click me<button>

Why do you want to write a new directive just to map your click event to a callback on your scope ? ng-click already does that for you.

The python 2.5 documentation explains it well.

Tuples and lists are compared lexicographically using comparison of corresponding elements. This means that to compare equal, each element must compare equal and the two sequences must be of the same type and have the same length.

If not equal, the sequences are ordered the same as their first differing elements. For example, cmp([1,2,x], [1,2,y]) returns the same as cmp(x,y). If the corresponding element does not exist, the shorter sequence is ordered first (for example, [1,2] < [1,2,3]).

Unfortunately that page seems to have disappeared in the documentation for more recent versions.

Also note, if you just want to see the changed files between the last commit and the one before it. This works fine: git show --name-only

Usually, if the command is an external program, you can use the OS to help you here.

command > file_output.txt

So your C code would be doing something like

exec("command > file_output.txt");

Then you can use the file_output.txt file.

function confirmDelete()
{
var r=confirm("Are you sure you want to delte this image");
if (r==true)
{
//User Pressed okay. Delete

}
else
{
//user pressed cancel. Do nothing
    }
 }
<img src="deleteicon.png" onclick="confirmDelete()">

You might want to pass some data with confirmDelete to determine which entry is to be deleted

I use PLAY JSON library you can find the mavn repo for only the JSON library not the whole framework here

    val json = "com.typesafe.play" %% "play-json" % version
    val typesafe = "typesafe.com" at "http://repo.typesafe.com/typesafe/releases/"

A very good tutorials about how to use them, are available here:

http://mandubian.com/2012/09/08/unveiling-play-2-dot-1-json-api-part1-jspath-reads-combinators/

In MYSQL server version: 5.0.27 i tried this and it worked fine for me check in your version

ALTER TABLE carmake
     MODIFY `country` ENUM('Japan', 'USA', 'England', 'Australia', 'Germany', 'France', 'Italy', 'Spain', 'Czech Republic', 'China', 'South Korea', 'India', 'Sweden', 'Malaysia');

I don't know if this is a bug or a feature, but there is very important (for some cases at least) difference I found: <input type="submit"> creates key value pair in your request and <button type="submit"> doesn't. Tested in Chrome and Safari.

So when you have multiple submit buttons in your form and want to know which one was clicked - do not use button, use input type="submit" instead.

Right click on the Project name > Configure > Convert to Maven Project > click finish. Here you will add some dependencies to download and add your expected jar file.

This will create an auto-generated pom.xml file. Open that file in xml format in your eclipse editor. After build tag (</build>) add your dependencies which you can copy from maven website and add them there. Now you are good to go. These dependencies will automatically add your required jar files.

You can use df.isnull().sum(). It shows all columns and the total NaNs of each feature.

And with Prototype:

$('yourDivId').setStyle({top: '100px', left:'80px'});

A one-liner solution. Result in bytes.

$size=array_sum(array_map('filesize', glob("{$dir}/*.*")));

Added bonus: you can simply change the file mask to whatever you like, and count only certain files (eg by extension).

date('Y-m', strtotime('first day of last month'));

Try below one:

svn copy http://svn.example.com/repos/calc/trunk@rev-no 
       http://svn.example.com/repos/calc/branches/my-calc-branch 
  -m "Creating a private branch of /calc/trunk."  --parents

No slash "\" between the svn URLs.

afaik to make a request to information_schema you need privileges. If you need simple list of keys you can use this command:

SHOW INDEXES IN <tablename>

The short answer is:

1. choose the iOS scheme from the drop-down near the run button from the menu bar
2. choose product > archive in the window that pops-up
3. click 'validate'
4. upon successful validation, click 'submit'

I sometimes use a bit of a trick to do just that. I put an invisible focus holder somewhere on the top of the layout. It would be e.g. like this

 <EditText android:id="@id/editInvisibleFocusHolder"
          style="@style/InvisibleFocusHolder"/>

with this style

<style name="InvisibleFocusHolder">
    <item name="android:layout_width">0dp</item>
    <item name="android:layout_height">0dp</item>
    <item name="android:focusable">true</item>
    <item name="android:focusableInTouchMode">true</item>
    <item name="android:inputType">none</item>
</style>

and then in onResume I would call

    editInvisibleFocusHolder.setInputType(InputType.TYPE_NULL);
    editInvisibleFocusHolder.requestFocus();

That works nicely for me from 1.6 up to 4.x

If they're meant to be separate values, try this:

var values = "554,20".split(",")
var v1 = parseFloat(values[0])
var v2 = parseFloat(values[1])

If they're meant to be a single value (like in French, where one-half is written 0,5)

var value = parseFloat("554,20".replace(",", "."));

"Access violation reading location 0x00000000" means that you're derefrencing a pointer that hasn't been initialized and therefore has garbage values. Those garbage values could be anything, but usually it happens to be 0 and so you try to read from the memory address 0x0, which the operating system detects and prevents you from doing.

Check and make sure that the array invaders[] is what you think it should be.

Also, you don't seem to be updating i ever - meaning that you keep placing the same Invader object into location 0 of invaders[] at every loop iteration.

Here is another dirty hack :)

.application-title > img {
display: none;
}

.application-title::before {
content: url(path/example.jpg);
}

How about this?

1. Your PHP script that holds the form saves a flag or some value into a database or file.
2. A second PHP script polls for this value periodically and if it's been set, it triggers the Email script in a synchronous manner.

This second PHP script should be set to run as a cron.

As an addition to @C??? answer, make sure the title of the tooltip has not already been set manually in the HTML element. In my case, the span class for the tooltip already had a fixed tittle text, because of this my JQuery function $('[data-toggle="tooltip"]').prop('title', 'your new title'); did not work.

When I removed the title attribute in the HTML span class, the jQuery was working.

So:

<span class="showTooltip" data-target="#showTooltip" data-id="showTooltip">
      <span id="MyTooltip" class="fas fa-info-circle" data-toggle="tooltip" data-placement="top" title="this is my pre-set title text"></span>
</span>

Should becode:

<span class="showTooltip" data-target="#showTooltip" data-id="showTooltip">
      <span id="MyTooltip" class="fas fa-info-circle" data-toggle="tooltip" data-placement="top"></span>
</span>

So far best solution that I've made:

function convertHtmlToJQueryObject(html){
    var htmlDOMObject = new DOMParser().parseFromString(html, "text/html");
    return $(htmlDOMObject.documentElement);
}

Just use gnome, just type in the address and away you go!

Try location.href='#yourId'

Like this:

<button onclick="javascript:location.href='#yourId'">Show</button>

   $('#textbox').on('keypress', function (e) {
         if(e.which === 13){

            //Disable textbox to prevent multiple submit
            $(this).attr("disabled", "disabled");

            //Do Stuff, submit, etc..

            //Enable the textbox again if needed.
            $(this).removeAttr("disabled");
         }
   });

There is already a Connect Middleware for Timeout support:

var timeout = express.timeout // express v3 and below
var timeout = require('connect-timeout'); //express v4

app.use(timeout(120000));
app.use(haltOnTimedout);

function haltOnTimedout(req, res, next){
  if (!req.timedout) next();
}

If you plan on using the Timeout middleware as a top-level middleware like above, the haltOnTimedOut middleware needs to be the last middleware defined in the stack and is used for catching the timeout event. Thanks @Aichholzer for the update.

Side Note:

Keep in mind that if you roll your own timeout middleware, 4xx status codes are for client errors and 5xx are for server errors. 408s are reserved for when:

The client did not produce a request within the time that the server was prepared to wait. The client MAY repeat the request without modifications at any later time.

Map.Entry is a key and its value combined into one class. This allows you to iterate over Map.entrySet() instead of having to iterate over Map.keySet(), then getting the value for each key. A better way to write what you have is:

for (Map.Entry<String, JButton> entry : listbouton.entrySet())
{
  String key = entry.getKey();
  JButton value = entry.getValue();

  this.add(value);
}

If this wasn't clear let me know and I'll amend my answer.

I will answer your question using a math analogy:

In this instance, the number 0 will represent no value. If you pick a random number, say 15, how many times can 0 be subtracted from 15? Infinite times because 0 has no value, thus you are taking nothing out of 15. Do you have difficulty accepting that 15 - 0 = 15 instead of ERROR? So if we switch this analogy back to Java coding, the String "" represents no value. Pick a random string, say "hello world", how many times can "" be subtracted from "hello world"?

I was getting the same issue and found that OpenSSH service was not running and it was causing the issue. After starting the SSH service it worked.

To check if SSH service is running or not:

ssh localhost

To start the service, if OpenSSH is already installed:

sudo /etc/init.d/ssh start

Incrementing date's year with vanilla js:

start_date_value = "01/01/2019"
var next_year = new Date(start_date_value);
next_year.setYear(next_year.getYear() + 1);
console.log(next_year.getYear()); //=> 2020

Just in case someone wants to increment other value than the date (day)

try it proxy package.json add code:

"proxy":"https://localhost:port"

and restart npm enjoy

same code

const instance = axios.create({
  baseURL: "/api/list", 
 
});

Try this:

$("a").removeAttr('href');

EDIT-

From your updated code:

 var location= $('#link1').attr("href");
 $("#link1").removeAttr('href');
 $('ul').addClass('expanded');
 $('ul.expanded').fadeIn(300);
 $("#link1").attr("href", location);

To align one flex child to the right set it withmargin-left: auto;

From the flex spec:

One use of auto margins in the main axis is to separate flex items into distinct "groups". The following example shows how to use this to reproduce a common UI pattern - a single bar of actions with some aligned on the left and others aligned on the right.

.wrap div:last-child {
  margin-left: auto;
}

Updated fiddle

.wrap {_x000D_
  display: flex;_x000D_
  background: #ccc;_x000D_
  width: 100%;_x000D_
  justify-content: space-between;_x000D_
}_x000D_

  <div>One</div>_x000D_
  <div>Two</div>_x000D_
  <div>Three</div>_x000D_
</div>

Note:

You could achieve a similar effect by setting flex-grow:1 on the middle flex item (or shorthand flex:1) which would push the last item all the way to the right. (Demo)

The obvious difference however is that the middle item becomes bigger than it may need to be. Add a border to the flex items to see the difference.

  display: flex;_x000D_

I suggest using the URLSearchParams interface:

const searchParams = new URLSearchParams();
const params = {foo: "hi there", bar: "100%" };
Object.keys(params).forEach(key => searchParams.append(key, params[key]));
console.log(searchParams.toString())

Or by passing the search object into the constructor like this:

const params = {foo: "hi there", bar: "100%" };
const queryString = new URLSearchParams(params).toString();
console.log(queryString);

This works:

sc.exe config "[servicename]" obj= "[.\username]" password= "[password]"

Where each of the [bracketed] items are replaced with the true arguments. (Keep the quotes, but don't keep the brackets.)

Just keep in mind that:

• The spacing in the above example matters. obj= "foo" is correct; obj="foo" is not.
• '.' is an alias to the local machine, you can specify a domain there (or your local computer name) if you wish.
• Passwords aren't validated until the service is started
• Quote your parameters, as above. You can sometimes get by without quotes, but good luck.

DSM has the accepted answer, but the coding doesn't seem to work for everyone. Here is one that works with the current version of pandas (0.23.4 as of 8/2018):

import pandas as pd

df = pd.DataFrame({'col1': [1, 2, 2, 3, 1],
            'col2': ['negative', 'positive', 'neutral', 'neutral', 'positive']})

conversion_dict = {'negative': -1, 'neutral': 0, 'positive': 1}
df['converted_column'] = df['col2'].replace(conversion_dict)

print(df.head())

You'll see it looks like:

   col1      col2  converted_column
0     1  negative                -1
1     2  positive                 1
2     2   neutral                 0
3     3   neutral                 0
4     1  positive                 1

The docs for pandas.DataFrame.replace are here.

Along with having something along the lines of : ENTRYPOINT ["tail", "-f", "/dev/null"] in your docker file, you should also run the docker container with -td option. This is particularly useful when the container runs on a remote m/c. Think of it more like you have ssh'ed into a remote m/c having the image and started the container. In this case, when you exit the ssh session, the container will get killed unless it's started with -td option. Sample command for running your image would be: docker run -td <any other additional options> <image name>

This holds good for docker version 20.10.2

Regexes can also limit the number of characters.

r = re.compile("^[a-z]{1,15}$")

gives you a regex that only matches if the input is entirely lowercase ASCII letters and 1 to 15 characters long.

In PyCharm go to

1. File ? Settings, or use Ctrl + Alt + S
2. < project name > ? Project Interpreter ? gear symbol ? Add Local
3. navigate to C:\Miniconda3\envs\my_env\python.exe, where my_env is the environment you want to use

Alternatively, in step 3 use C:\Miniconda3\python.exe if you did not create any further environments (if you never invoked conda create -n my_env python=3).

You can get a list of your current environments with conda info -e and switch to one of them using activate my_env.

__call__ is also used to implement decorator classes in python. In this case the instance of the class is called when the method with the decorator is called.

class EnterExitParam(object):

    def __init__(self, p1):
        self.p1 = p1

    def __call__(self, f):
        def new_f():
            print("Entering", f.__name__)
            print("p1=", self.p1)
            f()
            print("Leaving", f.__name__)
        return new_f


@EnterExitParam("foo bar")
def hello():
    print("Hello")


if __name__ == "__main__":
    hello()

program output:

Entering hello
p1= foo bar
Hello
Leaving hello

Here is how you would construct your query for this type of requirement.

select ID,Item_Name,max(Flavor) as Flavor,max(Extra_Cheese) as Extra_Cheese
    from (select i.*,
                    case when o.Option_Number=43 then o.value else null end as Flavor,
                    case when o.Option_Number=44 then o.value else null end as Extra_Cheese
                from Ordered_Item i,Ordered_Options o) a
    group by ID,Item_Name;

You basically "case out" each column using case when, then select the max() for each of those columns using group by for each intended item.

In Swift 3 there are some changes. Here is an extension to UIImage:

public extension UIImage {
    public func resize(height: CGFloat) -> UIImage? {
        let scale = height / self.size.height
        let width = self.size.width * scale
        UIGraphicsBeginImageContext(CGSize(width: width, height: height))
        self.draw(in: CGRect(x:0, y:0, width:width, height:height))
        let resultImage = UIGraphicsGetImageFromCurrentImageContext()
        UIGraphicsEndImageContext()
        return resultImage
    }
}

The swoole extension. https://github.com/matyhtf/swoole Asynchronous & concurrent networking framework for PHP.

$client = new swoole_client(SWOOLE_SOCK_TCP, SWOOLE_SOCK_ASYNC);

$client->on("connect", function($cli) {
    $cli->send("hello world\n");
});

$client->on("receive", function($cli, $data){
    echo "Receive: $data\n";
});

$client->on("error", function($cli){
    echo "connect fail\n";
});

$client->on("close", function($cli){
    echo "close\n";
});

$client->connect('127.0.0.1', 9501, 0.5);

$.ajax() is the most configurable one, where you get fine grained control over HTTP headers and such. You're also able to get direct access to the XHR-object using this method. Slightly more fine-grained error-handling is also provided. Can therefore be more complicated and often unecessary, but sometimes very useful. You have to deal with the returned data yourself with a callback.

$.get() is just a shorthand for $.ajax() but abstracts some of the configurations away, setting reasonable default values for what it hides from you. Returns the data to a callback. It only allows GET-requests so is accompanied by the $.post() function for similar abstraction, only for POST

.load() is similar to $.get() but adds functionality which allows you to define where in the document the returned data is to be inserted. Therefore really only usable when the call only will result in HTML. It is called slightly differently than the other, global, calls, as it is a method tied to a particular jQuery-wrapped DOM element. Therefore, one would do: $('#divWantingContent').load(...)

It should be noted that all $.get(), $.post(), .load() are all just wrappers for $.ajax() as it's called internally.

I think the textbox you are trying to access is not yet loaded onto the page at the time your javascript is being executed.

ie., For the Javascript to be able to read the textbox from the DOM of the page, the textbox must be available as an element. If the javascript is getting called before the textbox is written onto the page, the textbox will not be visible and so NULL is returned.

The general consensus is that you do not (should not) need to dispose of HttpClient.

Many people who are intimately involved in the way it works have stated this.

See Darrel Miller's blog post and a related SO post: HttpClient crawling results in memory leak for reference.

I'd also strongly suggest that you read the HttpClient chapter from Designing Evolvable Web APIs with ASP.NET for context on what is going on under the hood, particularly the "Lifecycle" section quoted here:

Although HttpClient does indirectly implement the IDisposable interface, the standard usage of HttpClient is not to dispose of it after every request. The HttpClient object is intended to live for as long as your application needs to make HTTP requests. Having an object exist across multiple requests enables a place for setting DefaultRequestHeaders and prevents you from having to re-specify things like CredentialCache and CookieContainer on every request as was necessary with HttpWebRequest.

Or even open up DotPeek.

use var array = entry.split("");

-(void) addBlurEffectOverImageView:(UIImageView *) _imageView
{
    UIVisualEffect *blurEffect;
    blurEffect = [UIBlurEffect effectWithStyle:UIBlurEffectStyleDark];

    UIVisualEffectView *visualEffectView;
    visualEffectView = [[UIVisualEffectView alloc] initWithEffect:blurEffect];

    visualEffectView.frame = _imageView.bounds;
    [_imageView addSubview:visualEffectView];
}

Use the return value of sprintf()

Buffer += sprintf(Buffer,"Hello World");
Buffer += sprintf(Buffer,"Good Morning");
Buffer += sprintf(Buffer,"Good Afternoon");

1. git checkout my_other_branch
2. git add my_file my_other_file
3. git commit -m

And provide your commit message.

>>> l = [list(range(i, i+4)) for i in range(10,1,-1)]
>>> l
[[10, 11, 12, 13], [9, 10, 11, 12], [8, 9, 10, 11], [7, 8, 9, 10], [6, 7, 8, 9], [5, 6, 7, 8], [4, 5, 6, 7], [3, 4, 5, 6], [2, 3, 4, 5]]
>>> sorted(l, key=sum)
[[2, 3, 4, 5], [3, 4, 5, 6], [4, 5, 6, 7], [5, 6, 7, 8], [6, 7, 8, 9], [7, 8, 9, 10], [8, 9, 10, 11], [9, 10, 11, 12], [10, 11, 12, 13]]

The above works. Are you doing something different?

Notice that your key function is just sum; there's no need to write it explicitly.

I forgot to mention. This should also accept whitespace.

You could use:

/^[-@.\/#&+\w\s]*$/

Note how this makes use of the character classes \w and \s.

EDIT:- Added \ to escape /

In my case it was because of other compile errors. When other errors have been solved this seemingly related error was also removed from the list. Specially the errors at the bottom of the errors list and on pages you have recently changed.

So do not pay attention to this error directly and focus on other errors at first.

To avoid this sort of trouble, you can use replace (which takes a plain string) instead of replaceAll (which takes a regular expression). You will still need to escape backslashes, but not in the wild ways required with regular expressions.

Try this:

$("#message span").text("hello world!");

See it in your code!

function Errormessage(txt) {
    var m = $("#message");

    // set text before displaying message
    m.children("span").text(txt);

    // bind close listener
    m.children("a.close-notify").click(function(){
      m.fadeOut("slow");
    });

    // display message
    m.fadeIn("slow");
}

inspect.getargspec()

Get the names and default values of a function’s arguments. A tuple of four things is returned: (args, varargs, varkw, defaults). args is a list of the argument names (it may contain nested lists). varargs and varkw are the names of the * and ** arguments or None. defaults is a tuple of default argument values or None if there are no default arguments; if this tuple has n elements, they correspond to the last n elements listed in args.

Changed in version 2.6: Returns a named tuple ArgSpec(args, varargs, keywords, defaults).

Whenever you type cast integer to char it will return the ascii value of that int (once go through the ascii table for better understanding)

    int a=68;
    char b=(char)a;

    System.out.println(b);//it will return ascii value of 68

    //output- D

You can use the sprintf method, however the arg method is preferred as it supports unicode.

QString str;
str.sprintf("%s %d", "string", 213);

I've come to the conclusion the best way to get the number of jobs on a queue is to use rabbitmqctl as has been suggested several times here. To allow any chosen user to run the command with sudo I followed the instructions here (I did skip editing the profile part as I don't mind typing in sudo before the command.)

I also grabbed jamesc's grep and cut snippet and wrapped it up in subprocess calls.

from subprocess import Popen, PIPE
p1 = Popen(["sudo", "rabbitmqctl", "list_queues", "-p", "[name of your virtula host"], stdout=PIPE)
p2 = Popen(["grep", "-e", "^celery\s"], stdin=p1.stdout, stdout=PIPE)
p3 = Popen(["cut", "-f2"], stdin=p2.stdout, stdout=PIPE)
p1.stdout.close()
p2.stdout.close()
print("number of jobs on queue: %i" % int(p3.communicate()[0]))

Here is another working example (@angular/cli 1.0.4):

proxy.conf.json :

{
  "/api/*" : {
    "target": "http://localhost:8181",
    "secure": false,
    "logLevel": "debug"
  },
  "/login.html" : {
    "target": "http://localhost:8181/login.html",
    "secure": false,
    "logLevel": "debug"
  }
}

run with :

ng serve --proxy-config proxy.conf.json

Seems based on benchmarks at JSPerf that using += is the fastest method, though not necessarily in every browser.

For building strings in the DOM, it seems to be better to concatenate the string first and then add to the DOM, rather then iteratively add it to the dom. You should benchmark your own case though.

(Thanks @zAlbee for correction)

Currently, ExplorerCanvas is the only option to emulate HTML5 canvas for IE6, 7, and 8. You're also right about its performance, which is pretty poor.

I found a particle simulatior that benchmarks the difference between true HTML5 canvas handling in Google Chrome, Safari, and Firefox, vs ExplorerCanvas in IE. The results show that the major browsers that do support the canvas tag run about 20 to 30 times faster than the emulated HTML5 in IE with ExplorerCanvas.

I doubt that anyone will go through the effort of creating an alternative because 1) excanvas.js is about as cleanly coded as it gets and 2) when IE9 is released all of the major browsers will finally support the canvas object. Hopefully, We'll get IE9 within a year

Best:

 std::string subCondition;

This creates an empty string.

This:

std::string myStr = "";

does a copy initialization - creates a temporary string from "", and then uses the copy constructor to create myStr.

Bonus:

std::string myStr("");

does a direct initialization and uses the string(const char*) constructor.

To check if a string is empty, just use empty().
