In a LinkedList the elements have a reference to the element before and after it. In an ArrayList the data structure is just an array.

1. A LinkedList needs to iterate over N elements to get the Nth element. An ArrayList only needs to return element N of the backing array.

2. The backing array needs to either be reallocated for the new size and the array copied over or every element after the deleted element needs to be moved up to fill the empty space. A LinkedList just needs to set the previous reference on the element after the removed to the one before the removed and the next reference on the element before the removed element to the element after the removed element. Longer to explain, but faster to do.

3. Same reason as deletion here.

Vertical alignment doesn't work with floated elements, indeed. That's because float lifts the element from the normal flow of the document. You might want to use other vertical aligning techniques, like the ones based on transform, display: table, absolute positioning, line-height, js (last resort maybe) or even the plain old html table (maybe the first choice if the content is actually tabular). You'll find that there's a heated debate on this issue.

However, this is how you can vertically align YOUR 3 divs:

.wrap{
    width: 500px;
    overflow:hidden;    
    background: pink;
}

.left {
    width: 150px;       
    margin-right: 10px;
    background: yellow;  
    display:inline-block;
    vertical-align: middle; 
}

.left2 {
    width: 150px;    
    margin-right: 10px;
    background: aqua; 
    display:inline-block;
    vertical-align: middle; 
}

.right{
    width: 150px;
    background: orange;
    display:inline-block;
    vertical-align: middle; 
}

Not sure why you needed both fixed width, display: inline-block and floating.

Here's a solution with flexbox for images with variable width and height:

.container {
  display: flex;
  flex-wrap: no-wrap;
  overflow-x: auto;
  margin: 20px;
}
img {
  flex: 0 0 auto;
  width: auto;
  height: 100px;
  max-width: 100%;
  margin-right: 10px;
}

We use WMI to get the mac address of the interface with the lowest metric, e.g. the interface windows will prefer to use, like this:

public static string GetMACAddress()
{
    ManagementObjectSearcher searcher = new ManagementObjectSearcher("SELECT * FROM Win32_NetworkAdapterConfiguration where IPEnabled=true");
    IEnumerable<ManagementObject> objects = searcher.Get().Cast<ManagementObject>();
    string mac = (from o in objects orderby o["IPConnectionMetric"] select o["MACAddress"].ToString()).FirstOrDefault();
    return mac;
}

Or in Silverlight (needs elevated trust):

public static string GetMACAddress()
{
    string mac = null;
    if ((Application.Current.IsRunningOutOfBrowser) && (Application.Current.HasElevatedPermissions) && (AutomationFactory.IsAvailable))
    {
        dynamic sWbemLocator = AutomationFactory.CreateObject("WbemScripting.SWBemLocator");
        dynamic sWbemServices = sWbemLocator.ConnectServer(".");
        sWbemServices.Security_.ImpersonationLevel = 3; //impersonate

        string query = "SELECT * FROM Win32_NetworkAdapterConfiguration where IPEnabled=true";
        dynamic results = sWbemServices.ExecQuery(query);

        int mtu = int.MaxValue;
        foreach (dynamic result in results)
        {
            if (result.IPConnectionMetric < mtu)
            {
                mtu = result.IPConnectionMetric;
                mac = result.MACAddress;
            }
        }
    }
    return mac;
}

items[node.ind] = items[node.ind]._replace(v=node.v)

(Note: Don't be discouraged to use this solution because of the leading underscore in the function _replace. Specifically for namedtuple some functions have leading underscore which is not for indicating they are meant to be "private")

I tried Gaby's answer (+1) above but it only partially solved my problem. Instead I used the following CSS, where content-box was changed to border-box:

input, select {
    -webkit-box-sizing: border-box;
       -moz-box-sizing: border-box;
            box-sizing: border-box;
}

You cannot open Java Applets (nor any other NPAPI plugin) in Microsoft Edge - they aren't supported and won't be added in the future.

Further you should be aware that in the next release of Google Chrome (v45 - due September 2015) NPAPI plugins will also no longer be supported.

Work-arounds

There are a couple of things that you can do:

Use Internet Explorer 11
You will find that in Windows 10 you will already have Internet Explorer 11 installed. IE 11 continues to support NPAPI (incl Java Applets). IE11 is squirrelled away (c:\program files\internet explorer\iexplore.exe). Just pin this exe to your task bar for easy access.

Use FireFox
You can also install and use a Firefox 32-bit Extended Support Release in Win10. Firefox have disabled NPAPI by default, but this can be overridden. This will only be supported until early 2018.

Order Collection Limit :

$orderCollection = Mage::getResourceModel('sales/order_collection'); 
$orderCollection->getSelect()->limit(10);

foreach ($orderCollection->getItems() as $order) :
   $orderModel = Mage::getModel('sales/order');
   $order =   $orderModel->load($order['entity_id']);
   echo $order->getId().'<br>'; 
endforeach; 

Blow codes could help you...

Fetch Numbers:

return string.Concat(input.Where(char.IsNumber));

Fetch Letters:

return string.Concat(input.Where(char.IsLetter));

I don't know why the answer seem so complicated... It seems pretty simple to do this with ps:

mem()
{                                                                                                      
    ps -eo rss,pid,euser,args:100 --sort %mem | grep -v grep | grep -i $@ | awk '{printf $1/1024 "MB"; $1=""; print }'
}

Example usage:

$ mem mysql
0.511719MB 781 root /bin/sh /usr/bin/mysqld_safe
0.511719MB 1124 root logger -t mysqld -p daemon.error
2.53516MB 1123 mysql /usr/sbin/mysqld --basedir=/usr --datadir=/var/lib/mysql --plugin-dir=/usr/lib/mysql/plugin --user=mysql --pid-file=/var/run/mysqld/mysqld.pid --socket=/var/run/mysqld/mysqld.sock --port=3306

Use the .IndexOf() method of the list. Specs for the method can be found on MSDN.

You should note that this is not necessarily the best design pattern. From the looks of it, you are essentially using your App Delegate to store what amounts to a global variable.

Matt Gallagher covered the issue of globals well in his Cocoa with Love article at http://cocoawithlove.com/2008/11/singletons-appdelegates-and-top-level.html. In all likelyhood, your ClassA should be a singleton rather than a global in the AppDelegate, although its possible you intent ClassA to be more general purpose and not simply a singleton. In that case, you'd probably be better off with either a class method to return a pre-configured instance of Class A, something like:

+ (ClassA*) applicationClassA
{
    static ClassA* appClassA = nil;
    if ( !appClassA ) {
        appClassA = [[ClassA alloc] init];
        appClassA.downloadURL = @"http://www.abc.com/";
    }
    return appClassA;
}

Or alternatively (since that would add application specific stuff to what is possibly a general purpose class), create a new class whose sole purpose is to contain that class method.

The point is that application globals do not need to be part of the AppDelegate. Just because the AppDelegate is a known singleton, does not mean every other app global should be mixed in with it even if they have nothing conceptually to do with handling the NSApplication delegate methods.

Another solution could be:

var eventsCustom = eventCustomRepository.FindAllEventsCustomByUniqueStudentReference(userDevice.UniqueStudentReference).AsEnumerable()
   .Where(x => x.DateTimeStart.Date == currentDate.Date).AsQueryable();

If you are ok with depending on system commands you can use the following:

Linux and Mac OS X:

import os
os.system('read -s -n 1 -p "Press any key to continue..."')
print()

Windows:

import os
os.system("pause")

Yes. You were missing a '{' under the public class line. And then one at the end of your code to close it.

Using C++ in MS Visual Studio 2015 (14), I use:

#include <chrono>

string NowToString()
{
  chrono::system_clock::time_point p = chrono::system_clock::now();
  time_t t = chrono::system_clock::to_time_t(p);
  char str[26];
  ctime_s(str, sizeof str, &t);
  return str;
}

Set the 'target' attribute of the link to _blank:

<a href="#" target="_blank" rel="noopener noreferrer">Link</a>

Edit: for other examples, see here: http://www.w3schools.com/tags/att_a_target.asp

(Note: I previously suggested blank instead of _blank because, if used, it'll open a new tab and then use the same tab if the link is clicked again. However, this is only because, as GolezTrol pointed out, it refers to the name a of a frame/window, which would be set and used when the link is pressed again to open it in the same tab).

Security Consideration!

The rel="noopener noreferrer" is to prevent the newly opened tab from being able to modify the original tab maliciously. For more information about this vulnerability see these resources:

If you want to set environment variables permanently in Git-Bash, you have two options:

1. Set a regular Windows environment variable. Git-bash gets all existing Windows environment variables at startupp.

2. Set up env variables in .bash_profile file.

.bash_profile is by default located in a user home folder, like C:\users\userName\git-home\.bash_profile. You can change the path to the bash home folder by setting HOME Windows environment variable.

.bash_profile file uses the regular Bash syntax and commands

# Export a variable in .bash_profile
export DIR=c:\dir
# Nix path style works too
export DIR=/c/dir

# And don't forget to add quotes if a variable contains whitespaces
export ANOTHER_DIR="c:\some dir"

Read more information about Bash configurations files.

This doesn't explain why it should be like that, but it explains why it could happen. The following byte-code sets -1 to the internal updateCount flag in the SQLServerStatement constructor:

// Method descriptor #401 (Lcom/microsoft/sqlserver/jdbc/SQLServerConnection;II)V
// Stack: 5, Locals: 8
SQLServerStatement(
  com.microsoft.sqlserver.jdbc.SQLServerConnection arg0, int arg1, int arg2) 
throws com.microsoft.sqlserver.jdbc.SQLServerException;

// [...]

34 aload_0 [this]
35 iconst_m1
36 putfield com.microsoft.sqlserver.jdbc.SQLServerStatement.updateCount:int [27]

Now, I will not analyse all possible control-flows, but I'd just say that this is the internal default initialisation value that somehow leaks out to client code. Note, this is also done in other methods:

// Method descriptor #383 ()V
// Stack: 2, Locals: 1
final void resetForReexecute() 
throws com.microsoft.sqlserver.jdbc.SQLServerException;

// [...]

10 aload_0 [this]
11 iconst_m1
12 putfield com.microsoft.sqlserver.jdbc.SQLServerStatement.updateCount:int [27]

// Method descriptor #383 ()V
// Stack: 3, Locals: 3
final void clearLastResult();
0 aload_0 [this]
1 iconst_m1
2 putfield com.microsoft.sqlserver.jdbc.SQLServerStatement.updateCount:int [27]

In other words, you're probably safe interpreting -1 as being the same as 0. If you rely on this result value, maybe stay on the safe side and do your checks as follows:

// No rows affected
if (stmt.executeUpdate() <= 0) {
}
// Rows affected
else {
}

UPDATE: While reading Mark Rotteveel's answer, I tend to agree with him, assuming that -1 is the JDBC-compliant value for "unknown update counts". Even if this isn't documented on the relevant method's Javadoc, it's documented in the JDBC specs, chapter 13.1.2.3 Returning Unknown or Multiple Results. In this very case, it could be said that an IF .. INSERT .. statement will have an "unknown update count", as this statement isn't SQL-standard compliant anyway.

On windows forms it is available, at the top of the class put

  static void Main(string[] args)
    {
        ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;
       //other stuff here
    }

since windows is single threaded, its all you need, in the event its a service you need to put it right above the call to the service (since there is no telling what thread you'll be on).

using System.Security.Principal 

is also needed.

RewriteEngine on
RewriteCond %{HTTP_HOST} ^(www\.)?olddomain\.com$ [NC]
RewriteRule ^(.*)$ "http://www.thenewdomain.com/" [R=301,L]

You should update the "Microsoft.CodeDom.Providers.DotNetCompilerPlatform" and "Microsoft.Net.Compilers" packages in your project .

You are incorrectly using the super and this keyword. Here is an example of how they work:

class Animal {
    public name: string;
    constructor(name: string) { 
        this.name = name;
    }
    move(meters: number) {
        console.log(this.name + " moved " + meters + "m.");
    }
}

class Horse extends Animal {
    move() {
        console.log(super.name + " is Galloping...");
        console.log(this.name + " is Galloping...");
        super.move(45);
    }
}

var tom: Animal = new Horse("Tommy the Palomino");

Animal.prototype.name = 'horseee'; 

tom.move(34);
// Outputs:

// horseee is Galloping...
// Tommy the Palomino is Galloping...
// Tommy the Palomino moved 45m.

Explanation:

1. The first log outputs super.name, this refers to the prototype chain of the object tom, not the object tom self. Because we have added a name property on the Animal.prototype, horseee will be outputted.
2. The second log outputs this.name, the this keyword refers to the the tom object itself.
3. The third log is logged using the move method of the Animal base class. This method is called from Horse class move method with the syntax super.move(45);. Using the super keyword in this context will look for a move method on the prototype chain which is found on the Animal prototype.

Remember TS still uses prototypes under the hood and the class and extends keywords are just syntactic sugar over prototypical inheritance.

I think it is better to use Array.Exists than Array.FindAll.

You need to stringify the object.

fs.writeFileSync('../data/phraseFreqs.json', JSON.stringify(output));

Webkit is the html/css rendering engine used in Apple's Safari browser, and in Google's Chrome. css values prefixes with -webkit- are webkit-specific, they're usually CSS3 or other non-standardised features.

to answer update 2 w3c is the body that tries to standardize these things, they write the rules, then programmers write their rendering engine to interpret those rules. So basically w3c says DIVs should work "This way" the engine-writer then uses that rule to write their code, any bugs or mis-interpretations of the rules cause the compatibility issues.

This code takes number of row and column from user then takes elements and displays as a matrix.

m = int(input('number of rows, m : '))
n = int(input('number of columns, n : '))
a=[]
for i in range(1,m+1):
  b = []
  print("{0} Row".format(i))
  for j in range(1,n+1):
    b.append(int(input("{0} Column: " .format(j))))
  a.append(b)
print(a)

If you want a Popup that closes automatically, you should look for Toasts. But if you want a dialog that the user has to close first before proceeding, you should look for a Dialog.

For both approaches it is possible to read a text file with the text you want to display. But you could also hardcode the text or use R.String to set the text.

Adding to the solution of array.slice(); be aware that if you have multidimensional array sub-arrays will be copied by references. What you can do is to loop and slice() each sub-array individually

var arr = [[1,1,1],[2,2,2],[3,3,3]];
var arr2 = arr.slice();

arr2[0][1] = 55;
console.log(arr2[0][1]);
console.log(arr[0][1]);

function arrCpy(arrSrc, arrDis){
 for(elm in arrSrc){
  arrDis.push(arrSrc[elm].slice());
}
}

var arr3=[];
arrCpy(arr,arr3);

arr3[1][1] = 77;

console.log(arr3[1][1]);
console.log(arr[1][1]);

same things goes to array of objects, they will be copied by reference, you have to copy them manually

I believe that if you download the offline ISO image file, and use that to install Visual Studio Express, you won't have to register.

Go here and find the link that says "All - Offline Install ISO image file". Click on it to expand it, select your language, and then click "Download".

Otherwise, it's possible that online registration is simply down for a while, as the error message indicates. You have 30 days before it expires, so give it a few days before starting to panic.

function createDate() {
            var date    = new Date(),
                yr      = date.getFullYear(),
                month   = date.getMonth()+1,
                day     = date.getDate(),
                todayDate = yr + '-' + month + '-' + day;
            console.log("Today date is :" + todayDate);

To resolve such 403 during push error you have to go in .git directory config file and change the given line:

precomposeunicode = true
[remote "origin"]
http://[email protected]:abc/xyz.git

Change the line to this

precomposeunicode = true
[remote "origin"]
ssh://[email protected]/abc/xyz.git

This resolved my issue.

Try vi with the -b option, this will show special end of line characters (I typically use it to see windows line endings in a txt file on a unix OS)

But if you want a scripted solution obviously vi wont work so you can try the -f or -e options with grep and pipe the result into sed or awk. From grep man page:

Matcher Selection -E, --extended-regexp Interpret PATTERN as an extended regular expression (ERE, see below). (-E is specified by POSIX.)

   -F, --fixed-strings
          Interpret PATTERN as a list of fixed strings, separated by newlines, any of which is to be matched.  (-F is specified
          by POSIX.)

Try this :

$('#input_id :selected').val(); //for getting value from selected option
$('#input_id :selected').text(); //for getting text from selected option

Reboot the phone.

Seriously! Completely power down and power up. That fixed it for me.

@everestial007 's solution worked for me. This is how I improved it for my use case, which is to have the columns of each different df with a different suffix so I can more easily differentiate between the dfs in the final merged dataframe.

from functools import reduce
import pandas as pd
dfs = [df1, df2, df3, df4]
suffixes = [f"_{i}" for i in range(len(dfs))]
# add suffixes to each df
dfs = [dfs[i].add_suffix(suffixes[i]) for i in range(len(dfs))]
# remove suffix from the merging column
dfs = [dfs[i].rename(columns={f"date{suffixes[i]}":"date"}) for i in range(len(dfs))]
# merge
dfs = reduce(lambda left,right: pd.merge(left,right,how='outer', on='date'), dfs)

the best way to calculate the equation is simplified. That is, find the maximum divisor between two numbers and divide:

ex.

1920:1080 maximum common divisor 120 = 16:9
1024:768  maximum common divisor 256 = 4:3
1280:768  maximum common divisor 256 = 5:3

may happen also some approaches

I was not able to copy Jenkins job from subfolder. copy from option did not show the suggestion which i was looking for.Without using suggestion copying the job name didn't work.

So if you want to create a job from outer folder, you need to first create the job in subfolder and then move it in different folder where you need to place it.

Suppose you want to check a boolean. If true, do something. Else, do something else. You can write:

if(condition==true){

}
else{   //else means this checks for the opposite of what you checked at if

}

instead of that, you can do it simply like:

if(condition){  //this will check if condition is true 

}
else{ 

}

Inversely. If you were to do something if condition was false and do something else if condition was true. Then you would write:

if(condition!=true){   //if(condition=false)

}
else{

}

But following the simple path. We do:

if(!condition){  //it reads out as: if condition is not true. Which means if condition is false right?

}
else{

}

Think about it. You'll get it in no time.

You can use xpath as follows, try this one :

driver.findElement(By.xpath("(.//[@href='/docs/configuration'])")).click();

With attribute selector we target input type text in CSS

input[type=text] {
background:gold;
font-size:15px;
 }

Check the namespace from where we are importing

import { MatDialogModule } from **"@angular/material/dialog";**
import { MatCardModule } from **"@angular/material/card";**
import { MatButtonModule } from **"@angular/material/button";**

If you want your dependency files to be in some specific folder you can simply use a copy task for it. For Eg.

task copyDepJars(type: Copy) {
  from configurations.compile
  into 'C:\\Users\\athakur\\Desktop\\lib'
}

Mine is a bit more smaller and simpler:

/// <summary>
/// Runs a PowerShell script taking it's path and parameters.
/// </summary>
/// <param name="scriptFullPath">The full file path for the .ps1 file.</param>
/// <param name="parameters">The parameters for the script, can be null.</param>
/// <returns>The output from the PowerShell execution.</returns>
public static ICollection<PSObject> RunScript(string scriptFullPath, ICollection<CommandParameter> parameters = null)
{
    var runspace = RunspaceFactory.CreateRunspace();
    runspace.Open();
    var pipeline = runspace.CreatePipeline();
    var cmd = new Command(scriptFullPath);
    if (parameters != null)
    {
        foreach (var p in parameters)
        {
            cmd.Parameters.Add(p);
        }
    }
    pipeline.Commands.Add(cmd);
    var results = pipeline.Invoke();
    pipeline.Dispose();
    runspace.Dispose();
    return results;
}

transferring file from local to remote host

scp -i (path of your key) (path for your file to be transferred) (username@ip):(path where file to be copied)

e.g scp -i aws.pem /home/user1/Desktop/testFile   ec2-user@someipAddress:/home/ec2-user/

P.S. - ec2-user@someipAddress of this ip address should have access to the destination folder in my case /home/ec2-user/

Actually I want timestamp based shorter unique identifier, hence tried the below program.

It is guessable with nanosecond + ( endians.length * endians.length ) combinations.

public class TimStampShorterUUID {

    private static final Character [] endians = 
           {'a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j', 
            'k', 'l', 'm', 'n', 'o', 'p', 'q', 'r', 's', 't', 
            'u', 'v', 'w', 'x', 'y', 'z', 
            'A', 'B', 'C', 'D', 'E', 'F', 'G', 'H', 'I', 'J', 
            'K', 'L', 'M', 'N', 'O', 'P', 'Q', 'R', 'S', 'T', 
            'U', 'V', 'W', 'X', 'Y', 'Z',
            '0', '1', '2', '3', '4', '5', '6', '7', '8', '9'
            };

   private static ThreadLocal<Character> threadLocal =  new ThreadLocal<Character>();

   private static AtomicLong iterator = new AtomicLong(-1);


    public static String generateShorterTxnId() {
        // Keep this as secure random when we want more secure, in distributed systems
        int firstLetter = ThreadLocalRandom.current().nextInt(0, (endians.length));

        //Sometimes your randomness and timestamp will be same value,
        //when multiple threads are trying at the same nano second
        //time hence to differentiate it, utilize the threads requesting
        //for this value, the possible unique thread numbers == endians.length
        Character secondLetter = threadLocal.get();
        if (secondLetter == null) {
            synchronized (threadLocal) {
                if (secondLetter == null) {
                    threadLocal.set(endians[(int) (iterator.incrementAndGet() % endians.length)]);
                }
            }
            secondLetter = threadLocal.get();
        }
        return "" + endians[firstLetter] + secondLetter + System.nanoTime();
    }


    public static void main(String[] args) {

UPDATE: This code will work on single JVM, but we should think on distributed JVM, hence i am thinking two solutions one with DB and another one without DB.

with DB

Company name (shortname 3 chars) ---- Random_Number ---- Key specific redis COUNTER
(3 char) ------------------------------------------------ (2 char) ---------------- (11 char)

without DB

IPADDRESS ---- THREAD_NUMBER ---- INCR_NUMBER ---- epoch milliseconds
(5 chars) ----------------- (2char) ----------------------- (2 char) ----------------- (6 char)

will update you once coding is done.

If you really need to go this way, then this is what you can do. There are probably better ways of doing it, but this is all that I have at the moment. I did no database calls, I just used dummy data. Please modify the code to fit in with your scenario. I used jQuery to populate the HTML table.

In my controller I have the an action method called GetEmployees that returns a JSON result with all the employees. This is where you would call your repository to return the users from a database:

public ActionResult GetEmployees()
{
     List<User> userList = new List<User>();

     User user1 = new User
     {
          Id = 1,
          FirstName = "First name 1",
          LastName = "Last name 1"
     };

     User user2 = new User
     {
          Id = 2,
          FirstName = "First name 2",
          LastName = "Last name 2"
     };

     userList.Add(user1);
     userList.Add(user2);

     return Json(userList, JsonRequestBehavior.AllowGet);
}

The User class looks like this:

public class User
{
     public int Id { get; set; }
     public string FirstName { get; set; }
     public string LastName { get; set; }
}

In your view you could have the following:

<div id="users">
     <table></table>
</div>

<script>

     $(document).ready(function () {

          var url = '/Home/GetEmployees';

          $.getJSON(url, function (data) {

               $.each(data, function (key, val) {

                    var user = '<tr><td>' + val.FirstName + '</td></tr>';

                    $('#users table').append(user);

               });
          });
     });

</script>

Regarding the code above: var url = '/Home/GetEmployees'; Home is the controller and GetEmployees is the action method that you defined above.

I hope this helps.

UPDATE:

This is how I would have done it..

I always create a view model class for a view. In this case I would have called it something like UserListViewModel:

public class UserListViewModel
{
     IEnumerable<User> Users { get; set; }
}

In my controller I would populate this Users list from a call to the database returning all the users:

public ActionResult List()
{
     UserListViewModel viewModel = new UserListViewModel
     {
          Users = userRepository.GetAllUsers()
     };

     return View(viewModel);
}

And in my view I would have the following:

<table>

@foreach(User user in Model.Users)
{
     <tr>
          <td>First Name:</td>
          <td>user.FirstName</td>
     </tr>
}

</table>

With JQuery this stuff is pretty easy to do. Since you can bind to sets.

Its NOT enough to do the onbeforeunload, you want to only trigger the navigate away if someone started editing stuff.

Just add plt.pyplot.show(), that would be fine.

The best solution is disabling SciView.

to allow periods and any other character just add them like so:

change: '#[^a-zA-Z ]#' to:'#[^a-zA-Z .()!]#'

You can use custom camera with thumbnail image. You can look my project.

1.Update project

Right Click on your project maven > update project

2.Build project

Right Click on your project again. run as > Maven build

If you have not created a “Run configuration” yet, it will open a new configuration with some auto filled values.

You can change the name. "Base directory" will be a auto filled value for you. Keep it as it is. Give maven command to ”Goals” fields.

i.e, “clean install” for building purpose

Click apply

Click run.

3.Run project on tomcat

Right Click on your project again. run as > Run-Configuration. It will open Run-Configuration window for you.

Right Click on “Maven Build” from the right side column and Select “New”. It will open a blank configuration for you.

Change the name as you want. For the base directory field you can choose values using 3 buttons(workspace,FileSystem,Variables). You can also copy and paste the auto generated value from previously created Run-configuration. Give the Goals as “tomcat:run”. Click apply. Click run.

If you want to get more clear idea with snapshots use the following link.

I tried the approach mentioned by Onkaar Singh,

1. Open POSTMAN
2. Click on "import" tab on the upper left side.
3. Select the Raw Text option and paste your cURL command.
4. Hit import and you will have the command in your Postman builder!

But the problem is it didn't work for the Apis which requires authorisation.

This was my curl request:

curl -v -H "Accept: application/json" -H "Content-type:
application/json" -X POST -d ' 
{"customer_id":"812122", "event":"add_to_cart", "email": "[email protected]", }' 
-u 9f4d7f5445e7: https://api.myapp.com/api/event

After importing the body got imported correctly, the headers and the Url also got imported. Only the api key 9f4d7f5445e7 which is

-u 9f4d7f5445e7: https://api.myapp.com/api/v1/event 

in the curl request did not import.

The way I solved it is, -u is basically used for Authorization. So while using it in Postman, you have to take the API key (which is 9f4d7f5445e7 in this case) and do Base64 Encode. Once encoded it will return the value OWY0ZDdmNTQ0NWU3. Then add a new header, the key name would be Authorization and key value would be Basic OWY0ZDdmNTQ0NWU3. After making that changes, the request worked for me.

There are online Base64 Encoders available, the one I used is http://www.url-encode-decode.com/base64-encode-decode/

Hope it helps!!!

This is Worked for me i have made the following changes in Style.xml

Change the Following Code:

<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">

With

<style name="AppTheme" parent="Base.Theme.AppCompat.Light.DarkActionBar">

If you are on Java 10, you can use var for that:

var ordinal = new Object() { int value; };
list.forEach(s -> {
    s.setOrdinal(ordinal.value);
    ordinal.value++;
});

Oracle optimizer chooses join order of tables for inner join. Optimizer chooses the join order of tables only in simple FROM clauses . U can check the oracle documentation in their website. And for the left, right outer join the most voted answer is right. The optimizer chooses the optimal join order as well as the optimal index for each table. The join order can affect which index is the best choice. The optimizer can choose an index as the access path for a table if it is the inner table, but not if it is the outer table (and there are no further qualifications).

The optimizer chooses the join order of tables only in simple FROM clauses. Most joins using the JOIN keyword are flattened into simple joins, so the optimizer chooses their join order.

The optimizer does not choose the join order for outer joins; it uses the order specified in the statement.

When selecting a join order, the optimizer takes into account: The size of each table The indexes available on each table Whether an index on a table is useful in a particular join order The number of rows and pages to be scanned for each table in each join order

As already mentioned by several people, eq is the right operator here.

If you use warnings; in your script, you'll get warnings about this (and many other useful things); I'd recommend use strict; as well.

Turn on gzip if you want to do it properly. You can also just do something like this:

$this->output = preg_replace(
    array(
        '/ {2,}/',
        '/<!--.*?-->|\t|(?:\r?\n[ \t]*)+/s'
    ),
    array(
        ' ',
        ''
    ),
    $this->output
);

This removes about 30% of the page size by turning your html into one line, no tabs, no new lines, no comments. Mileage may vary

You can create a scaling factor which is applied to the second geom and right y-axis. This is derived from Sebastian's solution.

library(ggplot2)

scaleFactor <- max(mtcars$cyl) / max(mtcars$hp)

ggplot(mtcars, aes(x=disp)) +
  geom_smooth(aes(y=cyl), method="loess", col="blue") +
  geom_smooth(aes(y=hp * scaleFactor), method="loess", col="red") +
  scale_y_continuous(name="cyl", sec.axis=sec_axis(~./scaleFactor, name="hp")) +
  theme(
    axis.title.y.left=element_text(color="blue"),
    axis.text.y.left=element_text(color="blue"),
    axis.title.y.right=element_text(color="red"),
    axis.text.y.right=element_text(color="red")
  )

Note: using ggplot2 v3.0.0

From the Overview tab of jQuery autocomplete plugin:

The local data can be a simple Array of Strings, or it contains Objects for each item in the array, with either a label or value property or both. The label property is displayed in the suggestion menu. The value will be inserted into the input element after the user selected something from the menu. If just one property is specified, it will be used for both, eg. if you provide only value-properties, the value will also be used as the label.

So your "two-dimensional" array could look like:

var $local_source = [{
    value: 1,
    label: "c++"
}, {
    value: 2,
    label: "java"
}, {
    value: 3,
    label: "php"
}, {
    value: 4,
    label: "coldfusion"
}, {
    value: 5,
    label: "javascript"
}, {
    value: 6,
    label: "asp"
}, {
    value: 7,
    label: "ruby"
}];

You can access the label and value properties inside focus and select event through the ui argument using ui.item.label and ui.item.value.

Edit

Seems like you have to "cancel" the focus and select events so that it does not place the id numbers inside the text boxes. While doing so you can copy the value in a hidden variable instead. Here is an example.

I might do something like the following. Of course, with the wealth of Collection classes, i can't imagine ever needing to use this in any practical code.

public class Shift {
  public static <T> T[] left (final T... i) {
    if (1 >= i.length) {
      return i;
    }
    final T t = i[0];
    int x = 0;
    for (; x < i.length - 1; x++) {
      i[x] = i[x + 1];
    }
    i[x] = t;
    return i;
  }
}

Called with two arguments, it's a swap.

It can be used as follows:

int x = 1;
int y = 2;
Integer[] yx = Shift.left(x,y);

Alternatively:

Integer[] yx = {x,y};
Shift.left(yx);

Then

x = yx[0];
y = yx[1];

Note: it auto-boxes primitives.

It's working for me:

File file = path.toFile();
String mimeType = Files.probeContentType(path);     

DiskFileItem fileItem = new DiskFileItem("file", mimeType, false, file.getName(), (int) file.length(),
            file.getParentFile());
fileItem.getOutputStream();
MultipartFile multipartFile = new CommonsMultipartFile(fileItem);

    try 
    {  
      String datestr="06/27/2007";
      DateFormat formatter; 
      Date date; 
      formatter = new SimpleDateFormat("MM/dd/yyyy");
      date = (Date)formatter.parse(datestr);  
    } 
    catch (Exception e)
    {}

month is MM, minutes is mm..

A faster way to do this is by right clicking the refresh icon beside the address bar and choosing Empty Cache and Hard reload

Just make sure Chrome's dev tools is open. (Press F12) By the way... This trick only works on Chrome for Windows, Ubuntu, and Mac OS

A very simple solution:

df <- read.csv("df.csv",sep=",",head=T)
x <- cbind(df$Xax,df$Xax,df$Xax,df$Xax)
y <- cbind(df$A,df$B,df$C,df$D)
matplot(x,y,type="p")

please note it just plots the data and it does not plot any regression line.

You could use the SQL%ROWCOUNT Oracle variable:

UPDATE table1
  SET field2 = value2, 
      field3 = value3 
WHERE field1 = value1; 

IF (SQL%ROWCOUNT = 0) THEN 

  INSERT INTO table (field1, field2, field3)
  VALUES (value1, value2, value3);

END IF; 

It would be easier just to determine if your primary key (i.e. field1) has a value and then perform an insert or update accordingly. That is, if you use said values as parameters for a stored procedure.

Javascript is flexible:

var arr = {
  "fred": {"apple": 2, "orange": 4},
  "mary": {}
  //etc, etc
};

alert(arr.fred.orange);
alert(arr["fred"]["orange"]);
for (key in arr.fred)
    alert(key + ": " + arr.fred[key]);

Just set in XAML:

        <TextBox IsReadOnly="True" Style="{x:Null}" />

So that text will not be grayed-out.

Spaces are horrible in filenames or directory names.

The correct syntax for this is to include every directory name that includes spaces, in double quotes

cmd /c C:\"Program Files"\"Microsoft Visual Studio 9.0"\Common7\IDE\devenv.com mysolution.sln /build "release|win32"

Edit: the api call has been removed by google. so it is no longer functioning.

Agree with Pareshkumar's answer. Now there is a python wrapper googlefinance for the url call.

Install googlefinance

$pip install googlefinance

It is easy to get current stock price:

>>> from googlefinance import getQuotes
>>> import json
>>> print json.dumps(getQuotes('AAPL'), indent=2)
[
  {
    "Index": "NASDAQ", 
    "LastTradeWithCurrency": "129.09", 
    "LastTradeDateTime": "2015-03-02T16:04:29Z", 
    "LastTradePrice": "129.09", 
    "Yield": "1.46", 
    "LastTradeTime": "4:04PM EST", 
    "LastTradeDateTimeLong": "Mar 2, 4:04PM EST", 
    "Dividend": "0.47", 
    "StockSymbol": "AAPL", 
    "ID": "22144"
  }
]

Google finance is a source that provides real-time stock data. There are also other APIs from yahoo, such as yahoo-finance, but they are delayed by 15min for NYSE and NASDAQ stocks.

You can try:

select(data, matches("search_string"))

It is more general than contains - you can use regex (e.g. "one_string|or_the_other").

For more examples, see: http://rpackages.ianhowson.com/cran/dplyr/man/select.html.

As seen in the other answers, the syntax to use is:

  30 2 * * * /your/command
# ^  ^
# |   hour
# minute

Following the crontab standard format:

 +---------------- minute (0 - 59)
 |  +------------- hour (0 - 23)
 |  |  +---------- day of month (1 - 31)
 |  |  |  +------- month (1 - 12)
 |  |  |  |  +---- day of week (0 - 6) (Sunday=0 or 7)
 |  |  |  |  |
 *  *  *  *  *  command to be executed

It is also useful to use crontab.guru to check crontab expressions.

The expressions are added into crontab using crontab -e. Once you are done, save and exit (if you are using vi, typing :x does it). The good think of using this tool is that if you write an invalid command you are likely to get a message prompt on the form:

$ crontab -e
crontab: installing new crontab
"/tmp/crontab.tNt1NL/crontab":7: bad minute
errors in crontab file, can't install.
Do you want to retry the same edit? (y/n) 

If you have further problems with crontab not running you can check Debugging crontab or Why is crontab not executing my PHP script?.

It is possible of course, use -l: instead of -l. For example -l:libXYZ.a to link with libXYZ.a. Notice the lib written out, as opposed to -lXYZ which would auto expand to libXYZ.

This is how I do it:

using System.IO;
using System.Security.Cryptography;

public string checkMD5(string filename)
{
    using (var md5 = MD5.Create())
    {
        using (var stream = File.OpenRead(filename))
        {
            return Encoding.Default.GetString(md5.ComputeHash(stream));
        }
    }
}

is null is the syntax I use for such things, when COALESCE is of no help.

Try:

if (@zipCode is null)
  begin
    ([Portal].[dbo].[Address].Position.Filter(@radiusBuff) = 1)   
  end
else 
  begin
    ([Portal].[dbo].[Address].PostalCode=@zipCode )
  end  

explode is an alternative. However, if you meant to split through a regular expression, the alternative is preg_split instead.

span {display:block;} also adds a line-break.

To avoid that, use span {display:inline-block;} and then you can add width and height to the inline element, and you can align it within the block as well:

span {
        display:inline-block;
        width: 5em;
        font-weight: normal;
        text-align: center
     }

You can get the path via fp.name. Example:

>>> f = open('foo/bar.txt')
>>> f.name
'foo/bar.txt'

You might need os.path.basename if you want only the file name:

>>> import os
>>> f = open('foo/bar.txt')
>>> os.path.basename(f.name)
'bar.txt'

Remy Sharp has a good description of the process in his article "Doing it right: skipping the iPhone url bar":

Making the iPhone hide the url bar is fairly simple, you need run the following JavaScript:

window.scrollTo(0, 1); 

However there's the question of when? You have to do this once the height is correct so that the iPhone can scroll to the first pixel of the document, otherwise it will try, then the height will load forcing the url bar back in to view.

You could wait until the images have loaded and the window.onload event fires, but this doesn't always work, if everything is cached, the event fires too early and the scrollTo never has a chance to jump. Here's an example using window.onload: http://jsbin.com/edifu4/4/

I personally use a timer for 1 second - which is enough time on a mobile device while you wait to render, but long enough that it doesn't fire too early:

setTimeout(function () {   window.scrollTo(0, 1); }, 1000);

However, you only want this to setup if it's an iPhone (or just mobile) browser, so a sneaky sniff (I don't generally encourage this, but I'm comfortable with this to prevent "normal" desktop browsers from jumping one pixel):

/mobile/i.test(navigator.userAgent) && setTimeout(function
() {   window.scrollTo(0, 1); }, 1000); 

The very last part of this, and this is the part that seems to be missing from some examples I've seen around the web is this: if the user specifically linked to a url fragment, i.e. the url has a hash on it, you don't want to jump. So if I navigate to http://full-frontal.org/tickets#dayconf - I want the browser to scroll naturally to the element whose id is dayconf, and not jump to the top using scrollTo(0, 1):

/mobile/i.test(navigator.userAgent) && !location.hash &&
setTimeout(function () {   window.scrollTo(0, 1); }, 1000);?

Try this out on an iPhone (or simulator) http://jsbin.com/edifu4/10 and you'll see it will only scroll when you've landed on the page without a url fragment.

Seems like a connection issue. You can use the Data link properties to find if the connection is fine. Do the following:

1. Create a blank notepad and rename it to "X.UDL"
2. Double click to open it
3. Under connections tab choose the server name/enter the name use the correct credentials and DB
4. Click OK to save it.

Now open the file in Notepad and compare the connection string properties.

Using interpolation string & format specifier:

var filename = $"{DateTime.Now:yyyy.dd.M HH-mm-ss}"

Example Output for January 1st, 2020 at 10:40:45AM:

2020.28.01 10-40-45

Or if you want a standard date format:

var filename = $"{DateTime.Now:yyyy.M.dd HH-mm-ss}"

Note: this feature is available in C# 6 and later versions of the language.

The people above have already pretty much explained the issue, but one thing that might make things clear is that, though people use <br/> and such all the time in HTML documents, any / in such a position is basically ignored, and only used when trying to make something both parseable as XML and HTML. Try <p/>foo</p>, for example, and you get a regular paragraph.

I had the same problem in letsencrypt (certbot) and nginx,

ref: https://github.com/certbot/certbot/issues/5486

this error does not have a solution yet

so, a changed a cron for renew (putting a reload after renew) (using suggest from certbot)

-- in /etc/cron.d/certbot
from
0 */12 * * * root test -x /usr/bin/certbot -a \! -d /run/systemd/system && perl -e 'sleep int(rand(3600))' && certbot -q renew 
to
0 */12 * * * root test -x /usr/bin/certbot -a \! -d /run/systemd/system && perl -e 'sleep int(rand(3600))' && certbot -q renew --pre-hook "service nginx stop" --post-hook "service nginx start"

Use This:

Update Table Set Column = CAST(NULL As Column Type) where Condition

Like This:

Update News Set Title = CAST(NULL As nvarchar(100)) Where ID = 50

This may not be as slick as a one-liner, but I use it to perform date manipulation mainly for reports:

DECLARE @Date datetime
SET @Date = GETDATE()

-- Set all time components to zero
SET @Date = DATEADD(ms, -DATEPART(ms, @Date), @Date) -- milliseconds = 0
SET @Date = DATEADD(ss, -DATEPART(ss, @Date), @Date) -- seconds = 0
SET @Date = DATEADD(mi, -DATEPART(mi, @Date), @Date) -- minutes = 0
SET @Date = DATEADD(hh, -DATEPART(hh, @Date), @Date) -- hours = 0

-- Extra manipulation for month and year
SET @Date = DATEADD(dd, -DATEPART(dd, @Date) + 1, @Date) -- day = 1
SET @Date = DATEADD(mm, -DATEPART(mm, @Date) + 1, @Date) -- month = 1

I use this to get hourly, daily, monthly, and yearly dates used for reporting and performance indicators, etc.

According to this issue comment, editing cross-env path will fix the problem. Change cross-env to node node_modules/cross-env/dist/bin/cross-env.js in package.json like this:

    "dev": "npm run development",
    "development": "node node_modules/cross-env/dist/bin/cross-env.js NODE_ENV=development node_modules/webpack/bin/webpack.js --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js",
    "watch": "node node_modules/cross-env/dist/bin/cross-env.js NODE_ENV=development node_modules/webpack/bin/webpack.js --watch --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js",
    "watch-poll": "npm run watch -- --watch-poll",
    "hot": "node node_modules/cross-env/dist/bin/cross-env.js NODE_ENV=development node_modules/webpack-dev-server/bin/webpack-dev-server.js --inline --hot --config=node_modules/laravel-mix/setup/webpack.config.js",
    "prod": "npm run production",
    "production": "node node_modules/cross-env/dist/bin/cross-env.js NODE_ENV=production node_modules/webpack/bin/webpack.js --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js"

I would use just getTime(); and for example Date.now() to return difference in milliseconds:

 //specified date:

var oneDate = new Date("November 02, 2017 06:00:00");

//number of milliseconds since midnight Jan 1 1970 till specified date

var oneDateMiliseconds = oneDate.getTime();

////number of milliseconds since midnight Jan 1 1970 till now

var currentMiliseconds = Date.now(); 

//return time difference in miliseconds

alert(currentMiliseconds-oneDateMiliseconds);

In short you have to do like this

repositories {
  maven { url "http://maven.springframework.org/release" }
  maven { url "https://maven.fabric.io/public" }
}

Detail:

You need to specify each maven URL in its own curly braces. Here is what I got working with skeleton dependencies for the web services project I’m going to build up:

apply plugin: 'java'

sourceCompatibility = 1.7
version = '1.0'

repositories {
  maven { url "http://maven.springframework.org/release" }
  maven { url "http://maven.restlet.org" }
  mavenCentral()
}

dependencies {
  compile group:'org.restlet.jee', name:'org.restlet', version:'2.1.1'
  compile group:'org.restlet.jee', name:'org.restlet.ext.servlet',version.1.1'
  compile group:'org.springframework', name:'spring-web', version:'3.2.1.RELEASE'
  compile group:'org.slf4j', name:'slf4j-api', version:'1.7.2'
  compile group:'ch.qos.logback', name:'logback-core', version:'1.0.9'
  testCompile group:'junit', name:'junit', version:'4.11'
}

SimpleDateFormat sdf = new SimpleDateFormat( "yyyy-MM-dd HH:mm:ss" );
// or SimpleDateFormat sdf = new SimpleDateFormat( "MM/dd/yyyy KK:mm:ss a Z" );
sdf.setTimeZone( TimeZone.getTimeZone( "UTC" ) );
System.out.println( sdf.format( new Date() ) );

you can use:

intent.setFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);

From MSDN

string value = "9quali52ty3";

// Convert the string into a byte[].
byte[] asciiBytes = Encoding.ASCII.GetBytes(value);

You now have an array of the ASCII value of the bytes. I got the following:

57 113 117 97 108 105 53 50 116 121 51

It must have been a problem with my Java install. I removed all traces of Java (C://program files/Java/jdk) and jre folders and reinstalled it from the official page and now it works fine.

You can add a hidden input with whatever value you need to send:

$('#form').submit(function(eventObj) {
    $(this).append('<input type="hidden" name="someName" value="someValue">');
    return true;
});

I haven't tried the discussed things myself, but the bigmemory package seems very useful

To check for assignability, you can use the Type.IsAssignableFrom method:

typeof(SomeType).IsAssignableFrom(typeof(Derived))

This will work as you expect for type-equality, inheritance-relationships and interface-implementations but not when you are looking for 'assignability' across explicit / implicit conversion operators.

To check for strict inheritance, you can use Type.IsSubclassOf:

typeof(Derived).IsSubclassOf(typeof(SomeType))

You're making an HTTP POST, but trying to pass parameters with the GET query string syntax. In a POST, the data are passed as named parameters and do not use the param=value&foo=bar syntax. Using jQuery's ajax method lets you create a javascript object with the named parameters, like so:

$.ajax({
  url: '/Home/SaveChart',
  type: 'POST',
  async: false,
  dataType: 'text',
  processData: false,    
  data: { 
      input: JSON.stringify(IVRInstant.data), 
      name: $("#wrkname").val()
  },
  success: function (data) { }
});

as suggested in other posts, probably you don't have any user defined. it's not advisable to manually edit the configuration files. you should use the add-user (.sh or .cmd) utility as explained in https://access.redhat.com/documentation/en-US/JBoss_Enterprise_Application_Platform/6/html/Installation_Guide/chap-Getting_Started_with_JBoss_Enterprise_Application_Platform_6.html#Add_the_Initial_User_for_the_Management_Interfaces

Angular 2.x && Angular 4.x do not support this out of the box

You can use this two pipes to iterate either by key or by value.

Keys pipe:

import {Pipe, PipeTransform} from '@angular/core'

@Pipe({
  name: 'keys',
  pure: false
})
export class KeysPipe implements PipeTransform {
  transform(value: any, args: any[] = null): any {
    return Object.keys(value)
  }
}

Values pipe:

import {Pipe, PipeTransform} from '@angular/core'

@Pipe({
  name: 'values',
  pure: false
})
export class ValuesPipe implements PipeTransform {
  transform(value: any, args: any[] = null): any {
    return Object.keys(value).map(key => value[key])
  }
}

How to use:

let data = {key1: 'value1', key2: 'value2'}

<div *ngFor="let key of data | keys"></div>
<div *ngFor="let value of data | values"></div>

create an xml gradient.xml file under drawable folder

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item>
        <shape android:shape="rectangle"  >
            <corners android:radius="50dip" />
            <stroke android:width="1dip" android:color="#667162" />
            <gradient android:angle="-90" android:startColor="#ffffff" android:endColor="#ffffff" />
        </shape>
    </item>
</selector>

then add this to your TextView

android:background="@drawable/gradient"

If you've already tried ctrl + c and it still doesn't work, you might want to try this. This has worked for me.

1. Run command-line as an Administrator. Then run the command below to find the processID (PID) you want to kill. Type your port number in <yourPortNumber>

   netstat -ano | findstr :<yourPortNumber>

2. Then you execute this command after you have identified the PID.

   taskkill /PID <typeYourPIDhere> /F

If the server is running as the foreground process in a terminal, this can be done by pressing

Ctrl-C

Another way to cleanly shut down a running server is to use the shutdown command,

> use admin
> db.shutdownServer();

Otherwise, a command like kill can be used to send the signal. If mongod has 10014 as its PID, the command would be

kill -2 10014

Default props with class component

Using static defaultProps is correct. You should also be using interfaces, not classes, for the props and state.

Update 2018/12/1: TypeScript has improved the type-checking related to defaultProps over time. Read on for latest and greatest usage down to older usages and issues.

For TypeScript 3.0 and up

TypeScript specifically added support for defaultProps to make type-checking work how you'd expect. Example:

interface PageProps {
  foo: string;
  bar: string;
}

export class PageComponent extends React.Component<PageProps, {}> {
    public static defaultProps = {
        foo: "default"
    };

    public render(): JSX.Element {
        return (
            <span>Hello, { this.props.foo.toUpperCase() }</span>
        );
    }
}

Which can be rendered and compile without passing a foo attribute:

<PageComponent bar={ "hello" } />

Note that:

• foo is not marked optional (ie foo?: string) even though it's not required as a JSX attribute. Marking as optional would mean that it could be undefined, but in fact it never will be undefined because defaultProps provides a default value. Think of it similar to how you can mark a function parameter optional, or with a default value, but not both, yet both mean the call doesn't need to specify a value. TypeScript 3.0+ treats defaultProps in a similar way, which is really cool for React users!
• The defaultProps has no explicit type annotation. Its type is inferred and used by the compiler to determine which JSX attributes are required. You could use defaultProps: Pick<PageProps, "foo"> to ensure defaultProps matches a sub-set of PageProps. More on this caveat is explained here.
• This requires @types/react version 16.4.11 to work properly.

For TypeScript 2.1 until 3.0

Before TypeScript 3.0 implemented compiler support for defaultProps you could still make use of it, and it worked 100% with React at runtime, but since TypeScript only considered props when checking for JSX attributes you'd have to mark props that have defaults as optional with ?. Example:

interface PageProps {
    foo?: string;
    bar: number;
}

export class PageComponent extends React.Component<PageProps, {}> {
    public static defaultProps: Partial<PageProps> = {
        foo: "default"
    };

    public render(): JSX.Element {
        return (
            <span>Hello, world</span>
        );
    }
}

Note that:

• It's a good idea to annotate defaultProps with Partial<> so that it type-checks against your props, but you don't have to supply every required property with a default value, which makes no sense since required properties should never need a default.
• When using strictNullChecks the value of this.props.foo will be possibly undefined and require a non-null assertion (ie this.props.foo!) or type-guard (ie if (this.props.foo) ...) to remove undefined. This is annoying since the default prop value means it actually will never be undefined, but TS didn't understand this flow. That's one of the main reasons TS 3.0 added explicit support for defaultProps.

Before TypeScript 2.1

This works the same but you don't have Partial types, so just omit Partial<> and either supply default values for all required props (even though those defaults will never be used) or omit the explicit type annotation completely.

Default props with Functional Components

You can use defaultProps on function components as well, but you have to type your function to the FunctionComponent (StatelessComponent in @types/react before version 16.7.2) interface so that TypeScript knows about defaultProps on the function:

interface PageProps {
  foo?: string;
  bar: number;
}

const PageComponent: FunctionComponent<PageProps> = (props) => {
  return (
    <span>Hello, {props.foo}, {props.bar}</span>
  );
};

PageComponent.defaultProps = {
  foo: "default"
};

Note that you don't have to use Partial<PageProps> anywhere because FunctionComponent.defaultProps is already specified as a partial in TS 2.1+.

Another nice alternative (this is what I use) is to destructure your props parameters and assign default values directly:

const PageComponent: FunctionComponent<PageProps> = ({foo = "default", bar}) => {
  return (
    <span>Hello, {foo}, {bar}</span>
  );
};

Then you don't need the defaultProps at all! Be aware that if you do provide defaultProps on a function component it will take precedence over default parameter values, because React will always explicitly pass the defaultProps values (so the parameters are never undefined, thus the default parameter is never used.) So you'd use one or the other, not both.

+ theme(plot.title = element_text(size=22))

Here is the full set of things you can change in element_text:

element_text(family = NULL, face = NULL, colour = NULL, size = NULL,
  hjust = NULL, vjust = NULL, angle = NULL, lineheight = NULL,
  color = NULL)

According to MDN, the split() method divides a String into an ordered set of substrings, puts these substrings into an array, and returns the array.

Example

var str = 'Hello my friend'

var split1 = str.split(' ') // ["Hello", "my", "friend"]
var split2 = str.split('') // ["H", "e", "l", "l", "o", " ", "m", "y", " ", "f", "r", "i", "e", "n", "d"]

In your case

var str = 'something -- something_else'
var splitArr = str.split(' -- ') // ["something", "something_else"]

console.log(splitArr[0]) // something
console.log(splitArr[1]) // something_else

See https://stackoverflow.com/a/12900859/104891.

First of all, set the language level/release versions in pom.xml like that:

<properties>
  <maven.compiler.source>1.8</maven.compiler.source>
  <maven.compiler.target>1.8</maven.compiler.target>
</properties>

Maven sets the default to 1.5 otherwise. You will also need to include the maven-compiler-plugin if you haven't already:

<dependency>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-compiler-plugin</artifactId>
  <version>3.8.1</version>
</dependency>

Also, try to change the Java version in each of these places:

File -> Project structure -> Project -> Project SDK -> 11.

File -> Project structure -> Project -> Project language level -> 11.

File -> Project structure -> Project -> Modules -> -> Sources --> 11

In project -> ctrl + alt + s -> Build, Execution, Deployment -> Compiler -> Java Compiler -> Project bytecode version -> 11

In project -> ctrl + alt + s -> Build, Execution, Deployment -> Compiler -> Java Compiler -> Module -> 1.11.

You can also do

SHOW STATUS WHERE `variable_name` = 'Max_used_connections';

for me following worked, just ran these command one by one

git pull -r origin master

git push -f origin your_branch

Use the String.split()

var array = string.split(',');

Things to ponder:

1. Use jquery
2. Which this is your code refering to
3. Isnt getElementById usually document.getElementById?
4. If the image is not found, are you sure your browser would tell you?

You don't need to rely on the preprocessor to ensure your enums and strings are in sync. To me using macros tend to make the code harder to read.

Using Enum And An Array Of Strings

enum fruit                                                                   
{
    APPLE = 0, 
    ORANGE, 
    GRAPE,
    BANANA,
    /* etc. */
    FRUIT_MAX                                                                                                                
};   

const char * const fruit_str[] =
{
    [BANANA] = "banana",
    [ORANGE] = "orange",
    [GRAPE]  = "grape",
    [APPLE]  = "apple",
    /* etc. */  
};

Note: the strings in the fruit_str array don't have to be declared in the same order as the enum items.

How To Use It

printf("enum apple as a string: %s\n", fruit_str[APPLE]);

Adding A Compile Time Check

If you are afraid to forget one string, you can add the following check:

#define ASSERT_ENUM_TO_STR(sarray, max) \                                       
  typedef char assert_sizeof_##max[(sizeof(sarray)/sizeof(sarray[0]) == (max)) ? 1 : -1]

ASSERT_ENUM_TO_STR(fruit_str, FRUIT_MAX);

An error would be reported at compile time if the amount of enum items does not match the amount of strings in the array.

You can suppress the compiler warnings and tell the generics that the code which you had written is legal according to it.

Example:

@SuppressWarnings("unchecked")
public List<ReservationMealPlan> retreiveMealPlan() {
     List<ReservationMealPlan> list=new ArrayList<ReservationMealPlan>();
    TestMenuService testMenuService=new TestMenuService(em, this.selectedInstance);
    list = testMenuService.getMeal(reservationMealPlan);
    return list;
 }

you could add an sed script to your commandline:

ls /home/user/new/*.txt | sed -r 's/^.+\///'

I have several computers, 32 and 64 bits processor, they run on Ubuntu Linux, Maverick (10.10) release.

I had the same problem, and for me, the sudo apt-get install libmysql-ruby libmysqlclient-dev did the job!!!

More simply:

city_name=city_name.replace(/ /gi,'_');

Replaces all spaces with '_'!

You can use the jobs -l command to get to a particular jobL

^Z
[1]+  Stopped                 guard

my_mac:workspace r$ jobs -l
[1]+ 46841 Suspended: 18           guard

In this case, 46841 is the PID.

From help jobs:

-l Report the process group ID and working directory of the jobs.

jobs -p is another option which shows just the PIDs.

The finally block is always run after the try block ends, whether try ends normally or abnormally due to an exception, er, throwable.

If an exception is thrown by any of the code within the try block, then the current method simply re-throws (or continues to throw) the same exception (after running the finally block).

If the finally block throws an exception / error / throwable, and there is already a pending throwable, it gets ugly. Quite frankly, I forget exactly what happens (so much for my certification years ago). I think both throwables get linked together, but there is some special voodoo you have to do (i.e. - a method call I would have to look up) to get the original problem before the "finally" barfed, er, threw up.

Incidentally, try/finally is a pretty common thing to do for resource management, since java has no destructors.

E.g. -

r = new LeakyThing();
try { useResource( r); }
finally { r.release(); }  // close, destroy, etc

"Finally", one more tip: if you do bother to put in a catch, either catch specific (expected) throwable subclasses, or just catch "Throwable", not "Exception", for a general catch-all error trap. Too many problems, such as reflection goofs, throw "Errors", rather than "Exceptions", and those will slip right by any "catch all" coded as:

catch ( Exception e) ...  // doesn't really catch *all*, eh?

do this instead:

catch ( Throwable t) ...

On Mac OS X (MBP), the following (taken from another answer found herein) resolved my issues:

C02L257NDV33:~ jjohnson$ brew install pip
Error: No available formula for pip
Homebrew provides pip via: `brew install python`. However you will then
have two Pythons installed on your Mac, so alternatively you can:
    sudo easy_install pip
C02L257NDV33:~ jjohnson$ sudo easy_install pip

Clearly the root cause here is having a secondary method by which to install python (in my case Homebrew). Hopefully, the people responsible for the pip script can remedy this issue since its still relevant 2 years after first being reported on Stack Overflow.

Based on @lijat, here is a simplified implementation. In my spring-based application I simply load this as a bean.

public static void configureLog4jFromSystemProperties()
{
  final String LOGGER_PREFIX = "log4j.logger.";

  for(String propertyName : System.getProperties().stringPropertyNames())
  {
    if (propertyName.startsWith(LOGGER_PREFIX)) {
      String loggerName = propertyName.substring(LOGGER_PREFIX.length());
      String levelName = System.getProperty(propertyName, "");
      Level level = Level.toLevel(levelName); // defaults to DEBUG
      if (!"".equals(levelName) && !levelName.toUpperCase().equals(level.toString())) {
        logger.error("Skipping unrecognized log4j log level " + levelName + ": -D" + propertyName + "=" + levelName);
        continue;
      }
      logger.info("Setting " + loggerName + " => " + level.toString());
      Logger.getLogger(loggerName).setLevel(level);
    }
  }
}

Here's an example of applying dropshadow to some svg using the 'filter' property. If you want to control the opacity of the dropshadow have a look at this example. The slope attribute controls how much opacity to give to the dropshadow.

Relevant bits from the example:

<filter id="dropshadow" height="130%">
  <feGaussianBlur in="SourceAlpha" stdDeviation="3"/> <!-- stdDeviation is how much to blur -->
  <feOffset dx="2" dy="2" result="offsetblur"/> <!-- how much to offset -->
  <feComponentTransfer>
    <feFuncA type="linear" slope="0.5"/> <!-- slope is the opacity of the shadow -->
  </feComponentTransfer>
  <feMerge> 
    <feMergeNode/> <!-- this contains the offset blurred image -->
    <feMergeNode in="SourceGraphic"/> <!-- this contains the element that the filter is applied to -->
  </feMerge>
</filter>
<circle r="10" style="filter:url(#dropshadow)"/>

Box-shadow is defined to work on CSS boxes (read: rectangles), while svg is a bit more expressive than just rectangles. Read the SVG Primer to learn a bit more about what you can do with SVG filters.

Here's the nearly shortest possible solution to your question. The solution works in python 3.x. For python 2.x change the import to Tkinter rather than tkinter (the difference being the capitalization):

import tkinter as tk
#import Tkinter as tk  # for python 2
    
def create_window():
    window = tk.Toplevel(root)

root = tk.Tk()
b = tk.Button(root, text="Create new window", command=create_window)
b.pack()

root.mainloop()

This is definitely not what I recommend as an example of good coding style, but it illustrates the basic concepts: a button with a command, and a function that creates a window.

You could also use plain Javascript window.innerWidth to compare width.

But use jQuery's .resize() fired automatically for you:

$( window ).resize(function() {
  // your code...
}); 

http://api.jquery.com/resize/

No, YAML does not include any kind of "import" or "include" statement.

If the result of, 'searchResult.Properties [ "user" ] [ 0 ]', is a string:

if ( ( searchResult.Properties [ "user" ].Count > 0 ) ) {

   profile.User = System.Text.Encoding.UTF8.GetString ( searchResult.Properties [ "user" ] [ 0 ].ToCharArray ().Select ( character => ( byte ) character ).ToArray () );

}

The key point being that converting a string to a byte [] can be done using LINQ:

.ToCharArray ().Select ( character => ( byte ) character ).ToArray () )

And the inverse:

.Select ( character => ( char ) character ).ToArray () )

I started by using the answers here, but modified it to use YouTube's new iframe embedding...

$('a.more').on('click', function(event) {
    event.preventDefault();
    $.fancybox({
        'type' : 'iframe',
        // hide the related video suggestions and autoplay the video
        'href' : this.href.replace(new RegExp('watch\\?v=', 'i'), 'embed/') + '?rel=0&autoplay=1',
        'overlayShow' : true,
        'centerOnScroll' : true,
        'speedIn' : 100,
        'speedOut' : 50,
        'width' : 640,
        'height' : 480
    });
});

In SQLDeveloper browse Tools --> Preferences, as shown in below image.



In the Preferences options expand Database --> select Advanced --> under "Tnsnames Directory" --> Browse the directory where tnsnames.ora present.
Then click on Ok.
as shown in below diagram.

You have Done!

Now you can connect via the TNSnames options.

You can basically switch the class using [ngClass]

for example

<button [ngClass]="{'active': selectedItem === 'item1'}" (click)="selectedItem = 'item1'">Button One</button>
<button [ngClass]="{'active': selectedItem === 'item2'}" (click)="selectedItem = 'item2'">Button Two</button>

you can use jQuery selectbox replacement. It's a jQuery plugin.

Use find with a wildcard:

find . -name 'mystring*'

sp_change_users_login is deprecated.

Much easier is:

ALTER USER usr1 WITH LOGIN = login1;

The difference can be demonstrated by this example:

1. generate a matrix

   >>> A = numpy.matrix(numpy.ones((3,3)))
   >>> A
   matrix([[ 1.,  1.,  1.],
           [ 1.,  1.,  1.],
           [ 1.,  1.,  1.]])
   

2. use numpy.array to modify A. Doesn't work because you are modifying a copy

   >>> numpy.array(A)[2]=2
   >>> A
   matrix([[ 1.,  1.,  1.],
           [ 1.,  1.,  1.],
           [ 1.,  1.,  1.]])
   

3. use numpy.asarray to modify A. It worked because you are modifying A itself

   >>> numpy.asarray(A)[2]=2
   >>> A
   matrix([[ 1.,  1.,  1.],
           [ 1.,  1.,  1.],
           [ 2.,  2.,  2.]])
   

Hope this helps!

Click just triggers the click event / events not the actually "goto-the-links-href" action.

You have to write your own handler and then your $('#myAnchor').trigger('click'); will work...

$("#myAnchor").click(function(event)
{
  var link = $(this);
  var target = link.attr("target");

  if($.trim(target).length > 0)
  {
    window.open(link.attr("href"), target);
  }
  else
  {
     window.location = link.attr("href");
  }

  event.preventDefault();
});

Although Simon Cross's answer is accepted and correct, I thought I would beef it up a bit with an example (Android) of what needs to be done. I'll keep it as general as I can and focus on just the question. Personally I wound up storing things in a database so the loading was smooth, but that requires a CursorAdapter and ContentProvider which is a bit out of scope here.

I came here myself and then thought, now what?!

The Issue

Just like user3594351, I was noticing the friend data was blank. I found this out by using the FriendPickerFragment. What worked three months ago, no longer works. Even Facebook's examples broke. So my issue was 'How Do I create FriendPickerFragment by hand?

What Did Not Work

Option #1 from Simon Cross was not strong enough to invite friends to the app. Simon Cross also recommended the Requests Dialog, but that would only allow five requests at a time. The requests dialog also showed the same friends during any given Facebook logged in session. Not useful.

What Worked (Summary)

Option #2 with some hard work. You must make sure you fulfill Facebook's new rules: 1.) You're a game 2.) You have a Canvas app (Web Presence) 3.) Your app is registered with Facebook. It is all done on the Facebook developer website under Settings.

To emulate the friend picker by hand inside my app I did the following:

1. Create a tab activity that shows two fragments. Each fragment shows a list. One fragment for available friend (/me/friends) and another for invitable friends (/me/invitable_friends). Use the same fragment code to render both tabs.
2. Create an AsyncTask that will get the friend data from Facebook. Once that data is loaded, toss it to the adapter which will render the values to the screen.

        int numberOfRecords = 0;
        JSONArray dataArray = (JSONArray) graphObject.getProperty("data");
        if (dataArray.length() > 0) {

            // Ensure the user has at least one friend ...
            for (int i = 0; i < dataArray.length(); i++) {

                JSONObject jsonObject = dataArray.optJSONObject(i);
                FacebookFriend facebookFriend = new FacebookFriend(jsonObject, pickType[0]);

                if (facebookFriend.isValid()) {
                    numberOfRecords++;

                    myList.add(facebookFriend);
                }
            }
        }

        // Make sure there are records to process
        if (numberOfRecords > 0){
            return true;
        } else {
            return false;
        }
    }

    @Override
    protected void onProgressUpdate(Boolean... booleans) {
        // No need to update this, wait until the whole thread finishes.
    }

    @Override
    protected void onPostExecute(Boolean result) {
        if (result) {
            /*
            User the array "myList" to create the adapter which will control showing items in the list.
             */

        } else {
            Log.i(TAG, "Facebook Thread unable to Get/Parse friend data. Type = " + pickType);
        }
    }

The FacebookFriend class I created

public class FacebookFriend {

    String facebookId;
    String name;
    String pictureUrl;
    boolean invitable;
    boolean available;
    boolean isValid;
    public enum Type {AVAILABLE, INVITABLE};

    public FacebookFriend(JSONObject jsonObject, Type type) {
        //
        //Parse the Facebook Data from the JSON object.
        //
        try {
            if (type == Type.INVITABLE) {
                //parse /me/invitable_friend
                this.facebookId =  jsonObject.getString("id");
                this.name = jsonObject.getString("name");

                // Handle the picture data.
                JSONObject pictureJsonObject = jsonObject.getJSONObject("picture").getJSONObject("data");
                boolean isSilhouette = pictureJsonObject.getBoolean("is_silhouette");
                if (!isSilhouette) {
                    this.pictureUrl = pictureJsonObject.getString("url");

                } else {
                    this.pictureUrl = "";
                }

                this.invitable = true;
            } else {
                // Parse /me/friends
                this.facebookId =  jsonObject.getString("id");
                this.name = jsonObject.getString("name");
                this.available = true;
                this.pictureUrl = "";
            }

            isValid = true;
        } catch (JSONException e) {
            Log.w("#", "Warnings - unable to process Facebook JSON: " + e.getLocalizedMessage());
        }
    }
}

This should do it using built in functions.

public static int minIndex (ArrayList<Float> list) {
  return list.indexOf (Collections.min(list)); }

I am working on an angular js app, andhavecome across a similar issue. What i did was display the image from the db, then created a button to remove or keep the current image. If the user decided to keep the current image, i changed the ng-submit attribute to another function whihc doesnt require image validation, and updated the record in the db without touching the original image path name. The remove image function also changed the ng-submit attribute value back to a function that submits the form and includes image validation and upload. Also a bit of javascript to slide the into view to upload a new image.

Cinn's answer is great, but there's one thing wrong with it.

The PreferredSize widget will start immediately at the top of the screen, without accounting for the status bar, so some of its height will be shadowed by the status bar's height. This also accounts for the side notches.

The solution: Wrap the preferredSize's child with a SafeArea

appBar: PreferredSize(
  //Here is the preferred height.
  preferredSize: Size.fromHeight(50.0),
  child: SafeArea(
    child: AppBar(
      flexibleSpace: ...
    ),
  ),
),

If you don't wanna use the flexibleSpace property, then there's no need for all that, because the other properties of the AppBar will account for the status bar automatically.

The best ans for me is to write the file / directory(to be copied) to the vagrant file directory, now any file present there is available to vagrant in path /vagrant.

That's it, no need of scp or any other methods,

similarly you can copy any file from VM to host by pasting in /vagrant directory.

Sipwiz is correct the only way to do this properly is the HTTP and DNS hybrid approach. My registrar is a re-seller for Tucows and they offer root domain forwarding as a free value added service.

If your domain is blah.com they will ask you where you would like the domain forwarded to, and you type in www.blah.com. They assign the A record to their apache server and automaticly add blah.com as a DNS vhost. The vhost responds with an HTTP 302 error redirecting them to the proper URL. It's simple to script/setup and can be handled by low end would otherwise be scrapped hardware.

Run the following command for an example: curl -v eclecticengineers.com

This has been partially answered here: MySQL Like multiple values

I advise against

$search = explode( ' ', $search );

and input them directly into the SQL query as this makes prone to SQL inject via the search bar. You will have to escape the characters first in case they try something funny like: "--; DROP TABLE name;

$search = str_replace('"', "''", search );

But even that is not completely safe. You must try to use SQL prepared statements to be safer. Using the regular expression is much easier to build a function to prepare and create what you want.

function makeSQL_search_pattern($search) {
    search_pattern = false;
    //escape the special regex chars
    $search = str_replace('"', "''", $search);
    $search = str_replace('^', "\\^", $search);
    $search = str_replace('$', "\\$", $search);
    $search = str_replace('.', "\\.", $search);
    $search = str_replace('[', "\\[", $search);
    $search = str_replace(']', "\\]", $search);
    $search = str_replace('|', "\\|", $search);
    $search = str_replace('*', "\\*", $search);
    $search = str_replace('+', "\\+", $search);
    $search = str_replace('{', "\\{", $search);
    $search = str_replace('}', "\\}", $search);
    $search = explode(" ", $search);
    for ($i = 0; $i < count($search); $i++) {
        if ($i > 0 && $i < count($search) ) {
           $search_pattern .= "|";
        }
        $search_pattern .= $search[$i];
    }
    return search_pattern;
}

$search_pattern = makeSQL_search_pattern($search);
$sql_query = "SELECT name FROM Products WHERE name REGEXP :search LIMIT 6"
$stmt = pdo->prepare($sql_query);
$stmt->bindParam(":search", $search_pattern, PDO::PARAM_STR);
$stmt->execute();

I have not tested this code, but this is what I would do in your case. I hope this helps.

I solved it by deleting "/.idea/libraries" from project. Thanks

you should man date first

date +%Y-%m-%d
date +%Y-%m-%d -d yesterday

you should change cr_date(str) to datetime object then you 'll change the date to the specific format:

cr_date = '2013-10-31 18:23:29.000227'
cr_date = datetime.datetime.strptime(cr_date, '%Y-%m-%d %H:%M:%S.%f')
cr_date = cr_date.strftime("%m/%d/%Y")

In mongodb _id field is reserved for primary key. Mongodb use an internal ObjectId value if you don't define it in your object and also create an index to ensure performance.

But you can put your own unique value for _id and Mongodb will use it instead of making one for you. And even if you want to use multiple field as primary key you can use an object:

{ _id : { a : 1, b: 1} }

Just be careful when creating these ids that the order of keys (a and b in the example) matters, if you swap them around, it is considered a different object.

This YouTube embed generator solve all my problems with video embedding.

I have written a component for the task, designed to handle large numbers of elements extremely fast (to the tune of <10ms for 1000 elements on a slow mobile).

It works with every type of scroll container you have access to – window, HTML elements, embedded iframe, spawned child window – and is very flexible in what it detects (full or partial visibility, border box or content box, custom tolerance zone, etc).

A huge, mostly auto-generated test suite ensures that it works as advertised, cross-browser.

Give it a shot if you like: jQuery.isInView. Otherwise, you might find inspiration in the source code, e.g. here.

Check whether you have put name="your_radio" where you have inserted radio tag

if you have done this then check your php code. Use isset()

e.g.

   if(isset($_POST['submit']))
   {
    /*other variables*/
    $radio_value = $_POST["your_radio"];
   }

If you have done this as well then we need to look through your codes

Try this

declare @v varchar(20)
set @v = 'Number'
select case when isnumeric(@v) = 1 then @v
else @v end

and

declare @v varchar(20)
set @v = '7082.7758172'
select case when isnumeric(@v) = 1 then @v
else convert(numeric(18,0),@v) end

A little bit more context: this works in JavaScript because of a language feature called "variable hoisting" - basically, think of it like variable/function declarations are put at the top of the scope (more info).

@Jonathan Leffler: Thank you. Your solution works.

A complete working example:

/** compile-time dispatch 

   $ gcc -Wall -DTEST_FUN=another_func macro_sub.c -o macro_sub && ./macro_sub
*/
#include <stdio.h>

#define QUOTE(name) #name
#define STR(macro) QUOTE(macro)

#ifndef TEST_FUN
#  define TEST_FUN some_func
#endif

#define TEST_FUN_NAME STR(TEST_FUN)

void some_func(void)
{
  printf("some_func() called\n");
}

void another_func(void)
{
  printf("do something else\n");
}

int main(void)
{
  TEST_FUN();
  printf("TEST_FUN_NAME=%s\n", TEST_FUN_NAME);
  return 0;
}

Example:

$ gcc -Wall -DTEST_FUN=another_func macro_sub.c -o macro_sub && ./macro_sub
do something else
TEST_FUN_NAME=another_func

but.onclick = function() { yourjavascriptfunction();};

or

but.onclick = function() { functionwithparam(param);};

Consider using a Spinner instead of a Number Picker in a Dialog. It's not exactly what was asked for, but it's much easier to implement, more contextual UI design, and should fulfill most use cases. The equivalent code for a Spinner is:

Spinner picker = new Spinner(this);
ArrayAdapter<String> adapter = new ArrayAdapter<String>(getActivity(), android.R.layout.simple_spinner_item, yourStringList);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
picker.setAdapter(adapter);

Using Guava you can easily combine different type of criteria. For your specific solution you can use:

value = CharMatcher.inRange('0', '9')
        .or(CharMatcher.inRange('a', 'z')
        .or(CharMatcher.inRange('A', 'Z'))).retainFrom(value)

a bit late but you can do this now by using $j(object).offset().left and .top accordingly.

In python, for loops iterate over iterables, instead of incrementing a counter, so you have a couple choices. Using a skip flag like Artsiom recommended is one way to do it. Another option is to make a generator from your range and manually advance it by discarding an element using next().

iGen = (i for i in range(0, 6))
for i in iGen:
    print i
    if not i % 2:
        iGen.next()

But this isn't quite complete because next() might throw a StopIteration if it reaches the end of the range, so you have to add some logic to detect that and break out of the outer loop if that happens.

In the end, I'd probably go with aw4ully's solution with the while loops.

There's a JS QrCode scanner, that works on mobile sites with a camera:

https://github.com/LazarSoft/jsqrcode

I have worked with it for one of my project and it works pretty good !

With regard to Brent.Longborough's answer (appering only on page 2 onward), perhaps you need to set the \thispagestyle{} after \begin{document}. I wonder if the letter class is setting the first page style to empty.

str.startswith allows you to supply a tuple of strings to test for:

if link.lower().startswith(("js", "catalog", "script", "katalog")):

From the docs:

str.startswith(prefix[, start[, end]])

Return True if string starts with the prefix, otherwise return False. prefix can also be a tuple of prefixes to look for.

Below is a demonstration:

>>> "abcde".startswith(("xyz", "abc"))
True
>>> prefixes = ["xyz", "abc"]
>>> "abcde".startswith(tuple(prefixes)) # You must use a tuple though
True
>>>

You have several options:

1. Use the standard FB Share button and set text via Open Graph API and meta tags on your page.
2. Instead of Share, use FB.ui's stream.publish method, which let's you control the URL, title, caption, description and thumbnail at run-time.
3. Or use http://www.facebook.com/sharer.php with appropriate parameters.

In swift 3 , to change UIBarButton back button arrow color

self.navigationController?.navigationBar.tintColor = UIColor.black

This ERROR can happen when you use Mockito to mock final classes.

Consider using Mockito inline or Powermock instead.

$("#ans").attr('checked') 

will tell you if it's checked. You can also use a second parameter true/false to check/uncheck the checkbox.

$("#ans").attr('checked', true);

Per comment, use prop instead of attr when available. E.g:

$("#ans").prop('checked')

For dynamic values!

<div class="col-md-4" ng-repeat="(k, v) in tiposAcesso">
    <label class="control-label">
        <input type="radio" name="tipoAcesso" ng-model="userLogin.tipoAcesso" value="{{k}}" ng-change="changeTipoAcesso(k)" />              
        <span ng-bind="v"></span>
    </label>
</div>

in controller

$scope.changeTipoAcesso = function(value) {
    console.log(value);
};

This can be done in 2 ways:

if (str.match(/abc|def/)) {
                       ...
                    }


if (/abc|def/.test(str)) {
                        ....
                    }

According to the matplotlib legend documentation:

The location can also be a 2-tuple giving the coordinates of the lower-left corner of the legend in axes coordinates (in which case bbox_to_anchor will be ignored).

Thus, one could use:

plt.legend(loc=(x, y))

to set the legend's lower left corner to the specified (x, y) position.

When I were trying install librosa package with pip (pip install librosa), this error were appeared:

ERROR: Cannot uninstall 'llvmlite'. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall.

I tried to remove llvmlite, but pip uninstall could not remove it. So, I used capability of ignore of pip by this code:

pip install librosa --ignore-installed llvmlite

Indeed, you can use this rule for ignoring a package you don't want to consider:

pip install {package you want to install} --ignore-installed {installed package you don't want to consider}

Just starting a new cmd-level from the command line gives you directly the version!

I'm not sure if I understand your question, but I'll take a stab at it:

Let's pretend you want to live in the immutable world and do NOT want to modify the original but want to create a new dict that is the result of adding a new key to the original.

In Python 3.5+ you can do:

params = {'a': 1, 'b': 2}
new_params = {**params, **{'c': 3}}

The Python 2 equivalent is:

params = {'a': 1, 'b': 2}
new_params = dict(params, **{'c': 3})

After either of these:

params is still equal to {'a': 1, 'b': 2}

and

new_params is equal to {'a': 1, 'b': 2, 'c': 3}

There will be times when you don't want to modify the original (you only want the result of adding to the original). I find this a refreshing alternative to the following:

params = {'a': 1, 'b': 2}
new_params = params.copy()
new_params['c'] = 3

or

params = {'a': 1, 'b': 2}
new_params = params.copy()
new_params.update({'c': 3})

Sharing a few functions which I created for dates:

Please note that I wanted to get time for a particular location (not just UTC time). If you want UTC time, just remove loc variable and .In(loc) function call.

func GetTimeStamp() string {
     loc, _ := time.LoadLocation("America/Los_Angeles")
     t := time.Now().In(loc)
     return t.Format("20060102150405")
}
func GetTodaysDate() string {
    loc, _ := time.LoadLocation("America/Los_Angeles")
    current_time := time.Now().In(loc)
    return current_time.Format("2006-01-02")
}

func GetTodaysDateTime() string {
    loc, _ := time.LoadLocation("America/Los_Angeles")
    current_time := time.Now().In(loc)
    return current_time.Format("2006-01-02 15:04:05")
}

func GetTodaysDateTimeFormatted() string {
    loc, _ := time.LoadLocation("America/Los_Angeles")
    current_time := time.Now().In(loc)
    return current_time.Format("Jan 2, 2006 at 3:04 PM")
}

func GetTimeStampFromDate(dtformat string) string {
    form := "Jan 2, 2006 at 3:04 PM"
    t2, _ := time.Parse(form, dtformat)
    return t2.Format("20060102150405")
}

GOOGLEFINANCE can have a 20 minutes delay, so refreshing every minute would not really help.

Instead of GOOGLEFINANCE you can use different source. I'm using this RealTime stock prices(I tried a couple but this is the easiest by-far to implement. They have API that retuen JSON { Name: CurrentPrice }

Here's a little script you can use in Google Sheets(Tools->Script Editor)

function GetStocksPrice() {      
   var url = 'https://financialmodelingprep.com/api/v3/stock/real-time- 
   price/AVP,BAC,CHK,CY,GE,GPRO,HIMX,IMGN,MFG,NIO,NMR,SSSS,UCTT,UMC,ZNGA';
   var response = UrlFetchApp.fetch(url);

   // convert json string to json object
   var jsonSignal = JSON.parse(response);    

  // define an array of all the object keys
  var headerRow = Object.keys(jsonSignal);
  // define an array of all the object values
  var values = headerRow.map(function(key){ return jsonSignal[key]});   
  var data = values[0];

  // get sheet by ID -  
  // you can get the sheet unqiue ID from the your current sheet url
  var jsonSheet = SpreadsheetApp.openById("Your Sheet UniqueID");  
  //var name = jsonSheet.getName();

  var sheet = jsonSheet.getSheetByName('Sheet1'); 

  // the column to put the data in -> Y
  var letter = "F";

  // start from line 
  var index = 4;
  data.forEach(function( row, index2 ) { 

     var keys = Object.keys(row);
     var value2 = row[keys[1]];            

     // set value loction
     var cellXY = letter +  index;      
     sheet.getRange(cellXY).setValue(value2);  
  
     index = index + 1;    
 });  
}

Now you need to add a trigger that will execute every minute.

1. Go to Project Triggers -> click on the Watch icon next to the Save icon
2. Add Trigger
3. In -> Choose which function to run -> GetStocksPrice
4. In -> Select event source -> Time-driven
5. In -> Select type of time based trigger -> Minutes timer
6. In -> Select minute interval -> Every minute

And your set :)

In 5.2.47 (at least on mac), go the location of the preferences is: MySQLWorkbench->Preferences->SQL Editor

Then you'll see both:

DBMS connection keep-alive interval (in seconds): DBMS connection read time out (in seconds):

The latter is where you'll want to up the limit from 600 to something a bit more.

Use RETURN QUERY:

CREATE OR REPLACE FUNCTION word_frequency(_max_tokens int)
  RETURNS TABLE (txt   text   -- also visible as OUT parameter inside function
               , cnt   bigint
               , ratio bigint) AS
$func$
BEGIN
   RETURN QUERY
   SELECT t.txt
        , count(*) AS cnt                 -- column alias only visible inside
        , (count(*) * 100) / _max_tokens  -- I added brackets
   FROM  (
      SELECT t.txt
      FROM   token t
      WHERE  t.chartype = 'ALPHABETIC'
      LIMIT  _max_tokens
      ) t
   GROUP  BY t.txt
   ORDER  BY cnt DESC;                    -- potential ambiguity 
END
$func$  LANGUAGE plpgsql;

Call:

SELECT * FROM word_frequency(123);

Explanation:

• It is much more practical to explicitly define the return type than simply declaring it as record. This way you don't have to provide a column definition list with every function call. RETURNS TABLE is one way to do that. There are others. Data types of OUT parameters have to match exactly what is returned by the query.

• Choose names for OUT parameters carefully. They are visible in the function body almost anywhere. Table-qualify columns of the same name to avoid conflicts or unexpected results. I did that for all columns in my example.

  But note the potential naming conflict between the OUT parameter cnt and the column alias of the same name. In this particular case (RETURN QUERY SELECT ...) Postgres uses the column alias over the OUT parameter either way. This can be ambiguous in other contexts, though. There are various ways to avoid any confusion:

  1. Use the ordinal position of the item in the SELECT list: ORDER BY 2 DESC. Example:
     • Select first row in each GROUP BY group?
  2. Repeat the expression ORDER BY count(*).
  3. (Not applicable here.) Set the configuration parameter plpgsql.variable_conflict or use the special command #variable_conflict error | use_variable | use_column in the function. See:
     • Naming conflict between function parameter and result of JOIN with USING clause

• Don't use "text" or "count" as column names. Both are legal to use in Postgres, but "count" is a reserved word in standard SQL and a basic function name and "text" is a basic data type. Can lead to confusing errors. I use txt and cnt in my examples.

• Added a missing ; and corrected a syntax error in the header. (_max_tokens int), not (int maxTokens) - type after name.

• While working with integer division, it's better to multiply first and divide later, to minimize the rounding error. Even better: work with numeric (or a floating point type). See below.

Alternative

This is what I think your query should actually look like (calculating a relative share per token):

CREATE OR REPLACE FUNCTION word_frequency(_max_tokens int)
  RETURNS TABLE (txt            text
               , abs_cnt        bigint
               , relative_share numeric) AS
$func$
BEGIN
   RETURN QUERY
   SELECT t.txt, t.cnt
        , round((t.cnt * 100) / (sum(t.cnt) OVER ()), 2)  -- AS relative_share
   FROM  (
      SELECT t.txt, count(*) AS cnt
      FROM   token t
      WHERE  t.chartype = 'ALPHABETIC'
      GROUP  BY t.txt
      ORDER  BY cnt DESC
      LIMIT  _max_tokens
      ) t
   ORDER  BY t.cnt DESC;
END
$func$  LANGUAGE plpgsql;

The expression sum(t.cnt) OVER () is a window function. You could use a CTE instead of the subquery - pretty, but a subquery is typically cheaper in simple cases like this one.

A final explicit RETURN statement is not required (but allowed) when working with OUT parameters or RETURNS TABLE (which makes implicit use of OUT parameters).

round() with two parameters only works for numeric types. count() in the subquery produces a bigint result and a sum() over this bigint produces a numeric result, thus we deal with a numeric number automatically and everything just falls into place.

You try to access private member of one class from another. The fact that bar-class is declared within foo-class means that bar in visible only inside foo class, but that is still other class.

And what is p->param?

Actually, it isn't clear what do you want to do

I solved my problem by upgrading my .NetFramework version from 4.5.2 to 4.7.2.

With a foreach:

let itemYouWant = null;
array.forEach((item) => {
    if (item.name === 'string 1') {
        itemYouWant = item;
    }
});
console.log(itemYouWant);

You can use node.js http module to do that. You could check the documentation at Node.js HTTP.

You would need to pass the query string as well to the other HTTP Server. You should have that in ServerRequest.url.

Once you have those info, you could pass in the backend HTTP Server and port in the options that you will provide in the http.request()

this.myService.getConfig().subscribe(
  (res) => console.log(res),
  (err) => console.log(err),
  () => console.log('done!')
);

Replace this line:

count(if(ccc_news_comments.id = 'approved', ccc_news_comments.id, 0)) AS comments

With this one:

coalesce(sum(ccc_news_comments.id = 'approved'), 0) comments

It's an extension for the User Controls you have in your project.

A user control is a kind of composite control that works much like an ASP.NET Web page—you can add existing Web server controls and markup to a user control, and define properties and methods for the control. You can then embed them in ASP.NET Web pages, where they act as a unit.

Simply, if you want to have some functionality that will be used on many pages in your project then you should create a User control or Composite control and use it in your pages. It just helps you to keep the same functionality and code in one place. And it makes it reusable.

An iframe has another scope, so you can't access it to style or to change its content with javascript.

It's basically "another page".
