Take a look at http://www.tingodb.com. I believe it does what you looking for. Additionally it fully compatible with MongoDB API. This reduces implementation risks and gives you option to switch to heavy solution as your app grows.

use this one. it will provide 60 spaces. that is your second parameter.

 echo str_repeat(" ", 60); 

To solve this issue you need below three steps:

1. Set page encoding to UTF-8 like below:

   <%@ page language="java" pageEncoding="UTF-8"%>
   <%@ page contentType="text/html;charset=UTF-8" %>
   

2. Set filter in web.xml file as below:

   <filter>
       <filter-name>encodingFilter</filter-name>
       <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
       <init-param>
           <param-name>forceEncoding</param-name>
           <param-value>true</param-value>
       </init-param>
       <init-param>
           <param-name>encoding</param-name>
           <param-value>UTF-8</param-value>
       </init-param>
   </filter>
   <filter-mapping>
       <filter-name>encodingFilter</filter-name>
       <url-pattern>/*</url-pattern>
   </filter-mapping>
   

3. Set resource encoding to UTF-8, in case if you are writing any UTF-8 characters in Java code or JSP directly.

This worked for me: :)

<button (click)="updatePendingApprovals(''+pendingApproval.personId, ''+pendingApproval.personId)">Approve</button>

updatePendingApprovals(planId: string, participantId: string) : void {
  alert('PlanId:' + planId + '    ParticipantId:' + participantId);
}

You can use : org.springframework.util.StringUtils;

String stringDelimitedByComma = StringUtils.collectionToCommaDelimitedString(myList);

You can use the Range object in VBA to set the value of a named cell, just like any other cell.

Range("C1").Value = Inputbox("Which job number would you like to add to the list?)

Where "C1" is the name of the cell you want to update.

My Excel VBA is a little bit old and crusty, so there may be a better way to do this in newer versions of Excel.

In case you have trouble building boost or prefer not to do that, an alternative is to download the lib files from SourceForge. The link will take you to a folder of zipped lib and dll files for version 1.51. But, you should be able to edit the link to specify the version of choice. Apparently the installer from BoostPro has some issues.

You can use the keyCode of the arrow keys (37, 38, 39 and 40 for left, up, right and down):

$('.selector').keydown(function (e) {
  var arrow = { left: 37, up: 38, right: 39, down: 40 };

  switch (e.which) {
    case arrow.left:
      //..
      break;
    case arrow.up:
      //..
      break;
    case arrow.right:
      //..
      break;
    case arrow.down:
      //..
      break;
  }
});

Check the above example here.

The best option is prepared statements. Messing around with quotes and escapes is harder work to begin with, and difficult to maintain. Sooner or later you will end up accidentally forgetting to quote something or end up escaping the same string twice, or mess up something like that. Might be years before you find those type of bugs.

According to https://ipython.org/ipython-doc/3/notebook/nbconvert.html you are looking for the nbconvert command with the --to script option.

ipython nbconvert notebook.ipynb --to script

While answers that refer to @ModelAttribute, @RequestParam, @PathParam and the likes are valid, there is a small gotcha I ran into. The resulting method parameter is a proxy that Spring wraps around your DTO. So, if you attempt to use it in a context that requires your own custom type, you may get some unexpected results.

The following will not work:

@GetMapping(produces = APPLICATION_JSON_VALUE)
public ResponseEntity<CustomDto> request(@ModelAttribute CustomDto dto) {
    return ResponseEntity.ok(dto);
}

In my case, attempting to use it in Jackson binding resulted in a com.fasterxml.jackson.databind.exc.InvalidDefinitionException.

You will need to create a new object from the dto.

if you have a nice selector (for example all .txt files in a dir) you could do:

for i in *.txt; do chmod 755 "$i"; done

bash for loop

or a variant of yours:

while read line; do chmod 755 "$line"; done < file.txt

If you are happy just catching Control-C, it's a done deal. If you really want non-blocking I/O but you don't want the curses library, another alternative is to move lock, stock, and barrel to the AT&T sfio library. It's nice library patterned on C stdio but more flexible, thread-safe, and performs better. (sfio stands for safe, fast I/O.)

It should be

var app = angular.module("MesaViewer", []);

This is the syntax you need to define a module and you need the array to show it has no dependencies.

You use the

angular.module("MesaViewer");

syntax when you are referencing a module you've already defined.

React doesn't really have an opinion about how you make REST calls. Basically you can choose whatever kind of AJAX library you like for this task.

The easiest way with plain old JavaScript is probably something like this:

var request = new XMLHttpRequest();
request.open('POST', '/my/url', true);
request.setRequestHeader('Content-Type', 'application/json; charset=UTF-8');
request.send(data);

In modern browsers you can also use fetch.

If you have more components that make REST calls it might make sense to put this kind of logic in a class that can be used across the components. E.g. RESTClient.post(…)

Differences might not be meaningful in a typical use case, but using the standard DOM functionality

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

is about twice as fast as

$("<div />").append($("#el").clone()).html();

so I would go with:

/* 
 * Return outerHTML for the first element in a jQuery object,
 * or an empty string if the jQuery object is empty;  
 */
jQuery.fn.outerHTML = function() {
   return (this[0]) ? this[0].outerHTML : '';  
};

The filter function can also provide an interesting solution:

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

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

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

You need to parse the string you are sending from javascript object to the JSON object

var json=$.parseJSON(data);

For anyone who wants to pass in arbitrary strings which are exact matches (And not worry about escaping regex special characters), git log takes a --fixed-strings option

git log --fixed-strings --grep "$SEARCH_TERM" 

This seems to be a little buggy in Pandas 0.23.4?

If there are np.nan values then this will throw an error as expected:

df['col'] = df['col'].astype(np.int64)

But doesn't change any values from float to int as I would expect if "ignore" is used:

df['col'] = df['col'].astype(np.int64,errors='ignore') 

It worked if I first converted np.nan:

df['col'] = df['col'].fillna(0).astype(np.int64)
df['col'] = df['col'].astype(np.int64)

Now I can't figure out how to get null values back in place of the zeroes since this will convert everything back to float again:

df['col']  = df['col'].replace(0,np.nan)

string utf8String = "Acción";
string propEncodeString = string.Empty;

byte[] utf8_Bytes = new byte[utf8String.Length];
for (int i = 0; i < utf8String.Length; ++i)
{
   utf8_Bytes[i] = (byte)utf8String[i];
}

propEncodeString = Encoding.UTF8.GetString(utf8_Bytes, 0, utf8_Bytes.Length);

Output should look like

Acción

day’s displays day's

call DecodeFromUtf8();

private static void DecodeFromUtf8()
{
    string utf8_String = "day’s";
    byte[] bytes = Encoding.Default.GetBytes(utf8_String);
    utf8_String = Encoding.UTF8.GetString(bytes);
}

I think you can stop at math.sqrt(n) instead of n/2.

I will give you example so that you can understand it easily. Now the sqrt(28) is 5.29 so ceil(5.29) will be 6. So I if I will stop at 6 then I will can get all the divisors. How?

First see the code and then see image:

import math
def divisors(n):
    divs = [1]
    for i in xrange(2,int(math.sqrt(n))+1):
        if n%i == 0:
            divs.extend([i,n/i])
    divs.extend([n])
    return list(set(divs))

Now, See the image below:

Lets say I have already added 1 to my divisors list and I start with i=2 so

So at the end of all the iterations as I have added the quotient and the divisor to my list all the divisors of 28 are populated.

Source: How to determine the divisors of a number

Source article: Passing a list as an argument to a vararg method

Use the toArray(T[] arr) method.

.getMap(locations.toArray(new WorldLocation[locations.size()]))

(toArray(new WorldLocation[0]) also works, but you would allocate a zero-length array for no reason.)

Here's a complete example:

public static void method(String... strs) {
    for (String s : strs)
        System.out.println(s);
}

...
    List<String> strs = new ArrayList<String>();
    strs.add("hello");
    strs.add("world");
    
    method(strs.toArray(new String[strs.size()]));
    //     ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Create a BufferedImage from file and make it TYPE_INT_RGB

import java.io.*;
import java.awt.image.*;
import javax.imageio.*;
public class Main{
    public static void main(String args[]){
        try{
            BufferedImage img = new BufferedImage( 
                500, 500, BufferedImage.TYPE_INT_RGB );
            File f = new File("MyFile.png");
            int r = 5;
            int g = 25; 
            int b = 255;
            int col = (r << 16) | (g << 8) | b;
            for(int x = 0; x < 500; x++){
                for(int y = 20; y < 300; y++){
                    img.setRGB(x, y, col);
                }
            }
            ImageIO.write(img, "PNG", f); 
        }
        catch(Exception e){ 
            e.printStackTrace();
        }
    }
}

This paints a big blue streak across the top.

If you want it ARGB, do it like this:

    try{
        BufferedImage img = new BufferedImage( 
            500, 500, BufferedImage.TYPE_INT_ARGB );
        File f = new File("MyFile.png");
        int r = 255;
        int g = 10;
        int b = 57;
        int alpha = 255;
        int col = (alpha << 24) | (r << 16) | (g << 8) | b;
        for(int x = 0; x < 500; x++){
            for(int y = 20; y < 30; y++){
                img.setRGB(x, y, col);
            }
        }
        ImageIO.write(img, "PNG", f);
    }
    catch(Exception e){
        e.printStackTrace();
    }

Open up MyFile.png, it has a red streak across the top.

So I discovered that in your ~/.zshrc file, there was a commented line,

# If you come from bash you might have to change your $PATH # export PATH=$HOME/bin:/usr/local/bin:$PATH

Just uncomment the export statement and all your previous bash_profile commands will also be there. If that comment does not exist, you can also just add that export statement to .zshrc file.

regarding Kevin answer to write in a folder tmp, it should be like this:

with open('./tmp/metadata.pdf', 'wb') as f:
    f.write(response.content)

he forgot . before the address and of-course your folder tmp should have been created already

Here's a simple way to get date without time if you are using Java 8+: Use java.time.LocalDate type instead of Date.

LocalDate now = LocalDate.now();
 System.out.println(now.toString());

The output:

Have you tried DevDefined.OAuth?

I have used it to secure my WebApi with 2-Legged OAuth. I have also successfully tested it with PHP clients.

It's quite easy to add support for OAuth using this library. Here's how you can implement the provider for ASP.NET MVC Web API:

1) Get the source code of DevDefined.OAuth: https://github.com/bittercoder/DevDefined.OAuth - the newest version allows for OAuthContextBuilder extensibility.

2) Build the library and reference it in your Web API project.

3) Create a custom context builder to support building a context from HttpRequestMessage:

using System;
using System.Collections.Generic;
using System.Collections.Specialized;
using System.Diagnostics.CodeAnalysis;
using System.Linq;
using System.Net.Http;
using System.Web;

using DevDefined.OAuth.Framework;

public class WebApiOAuthContextBuilder : OAuthContextBuilder
{
    public WebApiOAuthContextBuilder()
        : base(UriAdjuster)
    {
    }

    public IOAuthContext FromHttpRequest(HttpRequestMessage request)
    {
        var context = new OAuthContext
            {
                RawUri = this.CleanUri(request.RequestUri), 
                Cookies = this.CollectCookies(request), 
                Headers = ExtractHeaders(request), 
                RequestMethod = request.Method.ToString(), 
                QueryParameters = request.GetQueryNameValuePairs()
                    .ToNameValueCollection(), 
            };

        if (request.Content != null)
        {
            var contentResult = request.Content.ReadAsByteArrayAsync();
            context.RawContent = contentResult.Result;

            try
            {
                // the following line can result in a NullReferenceException
                var contentType = 
                    request.Content.Headers.ContentType.MediaType;
                context.RawContentType = contentType;

                if (contentType.ToLower()
                    .Contains("application/x-www-form-urlencoded"))
                {
                    var stringContentResult = request.Content
                        .ReadAsStringAsync();
                    context.FormEncodedParameters = 
                        HttpUtility.ParseQueryString(stringContentResult.Result);
                }
            }
            catch (NullReferenceException)
            {
            }
        }

        this.ParseAuthorizationHeader(context.Headers, context);

        return context;
    }

    protected static NameValueCollection ExtractHeaders(
        HttpRequestMessage request)
    {
        var result = new NameValueCollection();

        foreach (var header in request.Headers)
        {
            var values = header.Value.ToArray();
            var value = string.Empty;

            if (values.Length > 0)
            {
                value = values[0];
            }

            result.Add(header.Key, value);
        }

        return result;
    }

    protected NameValueCollection CollectCookies(
        HttpRequestMessage request)
    {
        IEnumerable<string> values;

        if (!request.Headers.TryGetValues("Set-Cookie", out values))
        {
            return new NameValueCollection();
        }

        var header = values.FirstOrDefault();

        return this.CollectCookiesFromHeaderString(header);
    }

    /// <summary>
    /// Adjust the URI to match the RFC specification (no query string!!).
    /// </summary>
    /// <param name="uri">
    /// The original URI. 
    /// </param>
    /// <returns>
    /// The adjusted URI. 
    /// </returns>
    private static Uri UriAdjuster(Uri uri)
    {
        return
            new Uri(
                string.Format(
                    "{0}://{1}{2}{3}", 
                    uri.Scheme, 
                    uri.Host, 
                    uri.IsDefaultPort ?
                        string.Empty :
                        string.Format(":{0}", uri.Port), 
                    uri.AbsolutePath));
    }
}

4) Use this tutorial for creating an OAuth provider: http://code.google.com/p/devdefined-tools/wiki/OAuthProvider. In the last step (Accessing Protected Resource Example) you can use this code in your AuthorizationFilterAttribute attribute:

public override void OnAuthorization(HttpActionContext actionContext)
{
    // the only change I made is use the custom context builder from step 3:
    OAuthContext context = 
        new WebApiOAuthContextBuilder().FromHttpRequest(actionContext.Request);

    try
    {
        provider.AccessProtectedResourceRequest(context);

        // do nothing here
    }
    catch (OAuthException authEx)
    {
        // the OAuthException's Report property is of the type "OAuthProblemReport", it's ToString()
        // implementation is overloaded to return a problem report string as per
        // the error reporting OAuth extension: http://wiki.oauth.net/ProblemReporting
        actionContext.Response = new HttpResponseMessage(HttpStatusCode.Unauthorized)
            {
               RequestMessage = request, ReasonPhrase = authEx.Report.ToString()
            };
    }
}

I have implemented my own provider so I haven't tested the above code (except of course the WebApiOAuthContextBuilder which I'm using in my provider) but it should work fine.

Views in Oracle may be updateable under specific conditions. It can be tricky, and usually is not advisable.

From the Oracle 10g SQL Reference:

Notes on Updatable Views

An updatable view is one you can use to insert, update, or delete base table rows. You can create a view to be inherently updatable, or you can create an INSTEAD OF trigger on any view to make it updatable.

To learn whether and in what ways the columns of an inherently updatable view can be modified, query the USER_UPDATABLE_COLUMNS data dictionary view. The information displayed by this view is meaningful only for inherently updatable views. For a view to be inherently updatable, the following conditions must be met:

• Each column in the view must map to a column of a single table. For example, if a view column maps to the output of a TABLE clause (an unnested collection), then the view is not inherently updatable.
• The view must not contain any of the following constructs:
  • A set operator
  • a DISTINCT operator
  • An aggregate or analytic function
  • A GROUP BY, ORDER BY, MODEL, CONNECT BY, or START WITH clause
  • A collection expression in a SELECT list
  • A subquery in a SELECT list
  • A subquery designated WITH READ ONLY
  • Joins, with some exceptions, as documented in Oracle Database Administrator's Guide

In addition, if an inherently updatable view contains pseudocolumns or expressions, then you cannot update base table rows with an UPDATE statement that refers to any of these pseudocolumns or expressions.

If you want a join view to be updatable, then all of the following conditions must be true:

• The DML statement must affect only one table underlying the join.
• For an INSERT statement, the view must not be created WITH CHECK OPTION, and all columns into which values are inserted must come from a key-preserved table. A key-preserved table is one for which every primary key or unique key value in the base table is also unique in the join view.
• For an UPDATE statement, all columns updated must be extracted from a key-preserved table. If the view was created WITH CHECK OPTION, then join columns and columns taken from tables that are referenced more than once in the view must be shielded from UPDATE.
• For a DELETE statement, if the join results in more than one key-preserved table, then Oracle Database deletes from the first table named in the FROM clause, whether or not the view was created WITH CHECK OPTION.

I would prevent loops in general if i can, set approaches are much more efficient:

INSERT INTO tblFoo
  SELECT TOP (300) n = ROW_NUMBER()OVER (ORDER BY [object_id]) 
  FROM sys.all_objects ORDER BY n;

Try This Code. here we have two longitude and latitude values and selected_location.distanceTo(near_locations) function returns the distance between those places in meters.

Location selected_location = new Location("locationA");
            selected_location.setLatitude(17.372102);
            selected_location.setLongitude(78.484196);
Location near_locations = new Location("locationB");
            near_locations.setLatitude(17.375775);
            near_locations.setLongitude(78.469218);
double distance = selected_location.distanceTo(near_locations);

here "distance" is distance between locationA & locationB (in Meters)

Use

const StartContainer = connect(null, mapDispatchToProps)(Start) 

instead of

const StartContainer = connect(mapDispatchToProps)(Start)

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

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

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

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

You can also use double quotes

x = """
this is 
a multiline
string
"""

2.3.3 :012 > x
 => "\nthis is\na multiline\nstring\n"

If needed to remove line breaks "\n" use backslash "\" at the end of each line

its kind of hacky but it works well-ish

 function close_frame(){
    if(!window.should_close){
        window.should_close=1;
    }else if(window.should_close==1){
        location.reload();
        //or iframe hide or whatever
    }
 }

 <iframe src="iframe_index.php" onload="close_frame()"></iframe>

then inside the frame

$('#close_modal_main').click(function(){
        window.location = 'iframe_index.php?close=1';
});

and if you want to get fancy through a

if(isset($_GET['close'])){
  die;
}

at the top of your frame page to make that reload unnoticeable

so basically the first time the frame loads it doesnt hide itself but the next time it loads itll call the onload function and the parent will have a the window var causing the frame to close

You can also use Route::current()->getName() to check your route name.

Example: routes.php

Route::get('test', ['as'=>'testing', function() {
    return View::make('test');
}]);

View:

@if(Route::current()->getName() == 'testing')
    Hello This is testing
@endif

Please try this:

byte[] decodedString = Base64.decode(person_object.getPhoto(),Base64.NO_WRAP);
InputStream inputStream  = new ByteArrayInputStream(decodedString);
Bitmap bitmap  = BitmapFactory.decodeStream(inputStream);
user_image.setImageBitmap(bitmap);

I know its late but i recently ran into this situation. After wasting entire day I finally found the solution. I am suprised that I got this info on oracle's website whereas this seems nowhere to be found on IBM's website.

If you want to use JDBC drivers for DB2 that are compatible with JDK 1.5 or 1.4 , you need to use the jar db2jcc.jar, which is available in SQLLIB/java/ folder of your db2 installation.

You may use scanf for this purpose with a little trick. Actually, you should allow user input until user hits Enter (\n). This will consider every character, including space. Here is example:

int main()
{
  char string[100], c;
  int i;
  printf("Enter the string: ");
  scanf("%s", string);
  i = strlen(string);      // length of user input till first space
  do
  {
    scanf("%c", &c);
    string[i++] = c;       // reading characters after first space (including it)
  } while (c != '\n');     // until user hits Enter
  string[i - 1] = 0;       // string terminating
return 0;
}

How this works? When user inputs characters from standard input, they will be stored in string variable until first blank space. After that, rest of entry will remain in input stream, and wait for next scanf. Next, we have a for loop that takes char by char from input stream (till \n) and apends them to end of string variable, thus forming a complete string same as user input from keyboard.

Hope this will help someone!

openSession: When you call SessionFactory.openSession, it always creates a new Session object and give it to you.

You need to explicitly flush and close these session objects.

As session objects are not thread safe, you need to create one session object per request in multi-threaded environment and one session per request in web applications too.

getCurrentSession: When you call SessionFactory.getCurrentSession, it will provide you session object which is in hibernate context and managed by hibernate internally. It is bound to transaction scope.

When you call SessionFactory.getCurrentSession, it creates a new Session if it does not exist, otherwise use same session which is in current hibernate context. It automatically flushes and closes session when transaction ends, so you do not need to do it externally.

If you are using hibernate in single-threaded environment , you can use getCurrentSession, as it is faster in performance as compared to creating a new session each time.

You need to add following property to hibernate.cfg.xml to use getCurrentSession method:

<session-factory>
    <!--  Put other elements here -->
    <property name="hibernate.current_session_context_class">
          thread
    </property>
</session-factory>

In my case, I had that error when I'm connected to VPN on my host but not on simulator. Turning the VPN off solved the issue

The json.load() method (without "s" in "load") can read a file directly:

import json
with open('strings.json') as f:
    d = json.load(f)
    print(d)

json.loads() method, which is used for string arguments only.

import json

person = '{"name": "Bob", "languages": ["English", "Fench"]}'
print(type(person))
# Output : <type 'str'>

person_dict = json.loads(person)
print( person_dict)
# Output: {'name': 'Bob', 'languages': ['English', 'Fench']}

print(type(person_dict))
# Output : <type 'dict'>

Here , we can see after using loads() takes a string ( type(str) ) as a input and return dictionary.

<form onSubmit="return captureForm()"> that should do. Make sure that your captureForm() method returns false.

Yes. Use GetValues() method in System.Enum class.

Try

echo getenv('COMPUTERNAME');

This will return your computername.

There is a solution using $element in the controller if you don't want to create another directive for this problem:

appControllers.controller('YourCtrl', ['$scope', '$timeout', '$element',
        function($scope, $timeout, $element) {

    $scope.updateTypeahead = function() {
       // ... some logic here
       $timeout(function() {
           $element[0].getElementsByClassName('search-query')[0].focus();
           // if you have unique id you can use $window instead of $element:
           // $window.document.getElementById('searchText').focus();
       });
    }
}]);

And this will work with ng-change:

<input id="searchText" type="text" class="search-query" ng-change="updateTypeahead()" ng-model="searchText" />

It doesn't work because it doesn't make sense (so little sense that HTML 5 explicitly forbids it).

To fix it, decide if you want a link or a submit button and use whichever one you actually want (Hint: You don't have a form, so a submit button is nonsense).

An example based on Chuck's answer:

myIntToStr :: Int -> String
myIntToStr x
    | x < 3     = show x ++ " is less than three"
    | otherwise = "normal"

Note that without the show the third line will not compile.

I know this question has already been answered, but I came here looking for a way to filter elements in an Array based on some criteria. So here is my solution example: using select, I find all constants in Class that start with "RUBY_"

Class.constants.select {|c| c.to_s =~ /^RUBY_/ }

UPDATE: In the meantime I have discovered that Array#grep works much better. For the above example,

Class.constants.grep /^RUBY_/

did the trick.

Late reply, but adding that Mongoose also has the concept of Subdocuments

With this syntax, you should be able to reference your userSchema as a type in your postSchema like so:

var userSchema = new Schema({
    twittername: String,
    twitterID: Number,
    displayName: String,
    profilePic: String,
});

var postSchema = new Schema({
    name: String,
    postedBy: userSchema,
    dateCreated: Date,
    comments: [{body:"string", by: mongoose.Schema.Types.ObjectId}],
});

Note the updated postedBy field with type userSchema.

This will embed the user object within the post, saving an extra lookup required by using a reference. Sometimes this could be preferable, other times the ref/populate route might be the way to go. Depends on what your application is doing.

Ricardo's answer is correct, however: sometimes you may find yourself in a situation where the container simply doesn't resize as desired as the browser window changes size, thus not allowing highcharts to resize itself.

This always works:

1. Set up a timed and pipelined resize event listener. Example with 500ms on jsFiddle
2. use chart.setSize(width, height, doAnimation = true); in your actual resize function to set the height and width dynamically
3. Set reflow: false in the highcharts-options and of course set height and width explicitly on creation. As we'll be doing our own resize event handling there's no need Highcharts hooks in another one.

I used Custom Action separately coded in C++ DLL and used the DLL to call appropriate function on Uninstalling using this syntax :

<CustomAction Id="Uninstall" BinaryKey="Dll_Name" 
              DllEntry="Function_Name" Execute="deferred" />

Using the above code block, I was able to run any function defined in C++ DLL on uninstall. FYI, my uninstall function had code regarding Clearing current user data and registry entries.

Using Postgres I had issues with DATEDIFF, but had success with this:

  DATE_PART('day',(delivery_time)::timestamp - (placed_time)::timestamp) * 24 + 
  DATE_PART('hour',(delivery_time)::timestamp - (placed_time)::timestamp) +
  DATE_PART('minute',(delivery_time)::timestamp - (placed_time)::timestamp) / 60

which gave me an output like "14.3"

In here:

    if (ValidationUtils.isNullOrEmpty(lastName)) {
        registrationErrors.add(ValidationErrors.LAST_NAME);
    }
    if (!ValidationUtils.isEmailValid(email)) {
        registrationErrors.add(ValidationErrors.EMAIL);
    }

you check for null or empty value on lastname, but in isEmailValid you don't check for empty value. Something like this should do

    if (ValidationUtils.isNullOrEmpty(email) || !ValidationUtils.isEmailValid(email)) {
        registrationErrors.add(ValidationErrors.EMAIL);
    }

or better yet, fix your ValidationUtils.isEmailValid() to cope with null email values. It shouldn't crash, it should just return false.

For ViewPager2,

viewPager.registerOnPageChangeCallback(object : ViewPager2.OnPageChangeCallback() {
  override fun onPageSelected(position: Int) {
    super.onPageSelected(position)
  }
})

where OnPageChangeCallback is a static class with three methods:

onPageScrolled(int position, float positionOffset, @Px int positionOffsetPixels),
onPageSelected(int position), 
onPageScrollStateChanged(@ScrollState int state)

The ffead-cpp provides multiple utility classes for various tasks, one such class is the Date class which provides a lot of features right from Date operations to date arithmetic, there's also a Timer class provided for timing operations. You can have a look at the same.

If you're doing this to several fields, or doing it quite often, then perhaps a plugin is the answer.
Here's the beginnings of a jQuery plugin that formats the value of a field to two decimal places.
It is triggered by the onchange event of the field. You may want something different.

<script type="text/javascript">

    // mini jQuery plugin that formats to two decimal places
    (function($) {
        $.fn.currencyFormat = function() {
            this.each( function( i ) {
                $(this).change( function( e ){
                    if( isNaN( parseFloat( this.value ) ) ) return;
                    this.value = parseFloat(this.value).toFixed(2);
                });
            });
            return this; //for chaining
        }
    })( jQuery );

    // apply the currencyFormat behaviour to elements with 'currency' as their class
    $( function() {
        $('.currency').currencyFormat();
    });

</script>   
<input type="text" name="one" class="currency"><br>
<input type="text" name="two" class="currency">

Curl has a specific option, --write-out, for this:

$ curl -o /dev/null --silent --head --write-out '%{http_code}\n' <url>
200

• -o /dev/null throws away the usual output
• --silent throws away the progress meter
• --head makes a HEAD HTTP request, instead of GET
• --write-out '%{http_code}\n' prints the required status code

To wrap this up in a complete Bash script:

#!/bin/bash
while read LINE; do
  curl -o /dev/null --silent --head --write-out "%{http_code} $LINE\n" "$LINE"
done < url-list.txt

(Eagle-eyed readers will notice that this uses one curl process per URL, which imposes fork and TCP connection penalties. It would be faster if multiple URLs were combined in a single curl, but there isn't space to write out the monsterous repetition of options that curl requires to do this.)

Cannot comment anymore but voted it up and wanted to let folks know that " works very well for the xml config files when forming regex expressions for RegexTransformer in Solr like so: regex=".*img src="(.*)".*" using the escaped version instead of double-quotes.

NOTE: The previous answers here aren't particularly useful if the BLOB is an arbitrary sequence of bytes; e.g. BINARY(16) to store 128-bit GUID or md5 checksum.

In that case, there currently is no editor preference -- though I have submitted a feature request now -- see that request for more detailed explanation.

[Until/unless that feature request is implemented], the solution is HEX function in a query: SELECT HEX(mybinarycolumn) FROM mytable.

An alternative is to use phpMyAdmin instead of MySQL Workbench - there hex is shown by default.

Corse-grained services provides broader functionalities as compared to fine-grained service. Depending on the business domain, a single service can be created to serve a single business unit or specialised multiple fine-grained services can be created if subunits are largely independent of each other. Coarse grained service may get more difficult may be less adaptable to change due to its size while fine-grained service may introduce additional complexity of managing multiple services.

For swift 3.0

if let url = URL(string: "tel://\(number)"), UIApplication.shared.canOpenURL(url) {
    if #available(iOS 10, *) {
        UIApplication.shared.open(url)
    } else {
        UIApplication.shared.openURL(url)
    }
}
else {
    print("Your device doesn't support this feature.")
}

There's no need to do this in two commits, you can add the file and mark it executable in a single commit:

C:\Temp\TestRepo>touch foo.sh

C:\Temp\TestRepo>git add foo.sh

C:\Temp\TestRepo>git ls-files --stage
100644 e69de29bb2d1d6434b8b29ae775ad8c2e48c5391 0       foo.sh

As you note, after adding, the mode is 0644 (ie, not executable). However, we can mark it as executable before committing:

C:\Temp\TestRepo>git update-index --chmod=+x foo.sh

C:\Temp\TestRepo>git ls-files --stage
100755 e69de29bb2d1d6434b8b29ae775ad8c2e48c5391 0       foo.sh

And now the file is mode 0755 (executable).

C:\Temp\TestRepo>git commit -m"Executable!"
[master (root-commit) 1f7a57a] Executable!
 1 file changed, 0 insertions(+), 0 deletions(-)
 create mode 100755 foo.sh

And now we have a single commit with a single executable file.

The selected answer would work for as long as you know the key itself that you want to delete but if it should be truly dynamic you would need to use the [] notation instead of the dot notation.

For example:

var keyToDelete = "key1";
var myObj = {"test": {"key1": "value", "key2": "value"}}

//that will not work.
delete myObj.test.keyToDelete 

instead you would need to use:

delete myObj.test[keyToDelete];

Substitute the dot notation with [] notation for those values that you want evaluated before being deleted.

I took Fredrik's method and modified the return type.

This way, the method supports deferred execution like other LINQ methods.

EDIT: If this wasn't clear, any usage of this method must end with ToList() or any other way to force the method to work on the complete enumerable. Otherwise, the action would not be performed!

public static IEnumerable<T> ForEach<T>(this IEnumerable<T> enumeration, Action<T> action)
{
    foreach (T item in enumeration)
    {
        action(item);
        yield return item;
    }
}

And here's the test to help see it:

[Test]
public void TestDefferedExecutionOfIEnumerableForEach()
{
    IEnumerable<char> enumerable = new[] {'a', 'b', 'c'};

    var sb = new StringBuilder();

    enumerable
        .ForEach(c => sb.Append("1"))
        .ForEach(c => sb.Append("2"))
        .ToList();

    Assert.That(sb.ToString(), Is.EqualTo("121212"));
}

If you remove the ToList() in the end, you will see the test failing since the StringBuilder contains an empty string. This is because no method forced the ForEach to enumerate.

You can check scrollHeight and clientHeight with scrollTop to scroll to bottom of div like code below.

$('#div').scroll(function (event) {_x000D_
  if ((parseInt($('#div')[0].scrollHeight) - parseInt(this.clientHeight)) == parseInt($('#div').scrollTop())) _x000D_
  {_x000D_
    console.log("this is scroll bottom of div");_x000D_
  }_x000D_
  _x000D_
});

if I expect a non-empty input

public static Function<Scanner,String> scanLine = (scan -> {
    String s = scan.nextLine();
    return( s.length() == 0 ? scan.nextLine() : s );
  });

used in above example:

System.out.println("Enter numerical value");    
int option = input.nextInt(); // read numerical value from input

System.out.println("Enter 1st string"); 
String string1 = scanLine.apply( input ); // read 1st string
System.out.println("Enter 2nd string");
String string2 = scanLine.apply( input ); // read 2nd string

In my case, I created a new project and when I ran it the first time, it gave me the following error:

An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using the exception stack trace below.

So my solution was to go to the Package Manager Console inside the Visual Studio and run:Update-Package

Problem solved!!

I was using this way:

        worksheet.get_Range(11, 1, 11, 41)
            .SetHeadFontStyle()
            .SetHeadFillStyle(45)
            .SetBorders(
                XlBorderWeight.xlMedium
                , XlBorderWeight.xlThick
                , XlBorderWeight.xlMedium
                , XlBorderWeight.xlThick)
            ;

SetHeadFontStyle / SetHeadFillStyle is ExtMethod of Range like below:

 public static Range SetHeadFillStyle(this Range rng, int colorIndex)
 {
     //do some operation
     return rng;
 }

do some operation and return the Range for next operation

it's look like Linq :)

but now still can't fully look like it -- propery set value

with cell.Border(xlEdgeTop)
   .LineStyle = xlContinuous
   .Weight = xlMedium
   .ColorIndex = xlAutomatic

Setting the underlying socket ReceiveTimeout property did the trick. You can access it like this: yourTcpClient.Client.ReceiveTimeout. You can read the docs for more information.

Now the code will only "sleep" as long as needed for some data to arrive in the socket, or it will raise an exception if no data arrives, at the beginning of a read operation, for more than 20ms. I can tweak this timeout if needed. Now I'm not paying the 20ms price in every iteration, I'm only paying it at the last read operation. Since I have the content-length of the message in the first bytes read from the server I can use it to tweak it even more and not try to read if all expected data has been already received.

I find using ReceiveTimeout much easier than implementing asynchronous read... Here is the working code:

string SendCmd(string cmd, string ip, int port)
{
  var client = new TcpClient(ip, port);
  var data = Encoding.GetEncoding(1252).GetBytes(cmd);
  var stm = client.GetStream();
  stm.Write(data, 0, data.Length);
  byte[] resp = new byte[2048];
  var memStream = new MemoryStream();
  var bytes = 0;
  client.Client.ReceiveTimeout = 20;
  do
  {
      try
      {
          bytes = stm.Read(resp, 0, resp.Length);
          memStream.Write(resp, 0, bytes);
      }
      catch (IOException ex)
      {
          // if the ReceiveTimeout is reached an IOException will be raised...
          // with an InnerException of type SocketException and ErrorCode 10060
          var socketExept = ex.InnerException as SocketException;
          if (socketExept == null || socketExept.ErrorCode != 10060)
              // if it's not the "expected" exception, let's not hide the error
              throw ex;
          // if it is the receive timeout, then reading ended
          bytes = 0;
      }
  } while (bytes > 0);
  return Encoding.GetEncoding(1252).GetString(memStream.ToArray());
}

If you bracket the @ you can use it directly

declare @TEMP table (ID int, Name varchar(max))
insert into @temp values (1,'one'), (2,'two')

SELECT * FROM @TEMP 
WHERE [@TEMP].[ID] = 1

I would suggest the following:

String[] parsedInput = str.split("\n"); String firstName = parsedInput[0].split(": ")[1]; String lastName = parsedInput[1].split(": ")[1]; myMap.put(firstName,lastName); 

It's also possible to use jQuery's .load()

$('#submitform').click(function() {
  $('#showresults').load('getinfo.asp #showresults', {
    txtsearch: $('#appendedInputButton').val()
  }, function() {
    // alert('Load was performed.')
    // $('#showresults').slideDown('slow')
  });
});

unlike $.get(), allows us to specify a portion of the remote document to be inserted. This is achieved with a special syntax for the url parameter. If one or more space characters are included in the string, the portion of the string following the first space is assumed to be a jQuery selector that determines the content to be loaded.

We could modify the example above to use only part of the document that is fetched:

$( "#result" ).load( "ajax/test.html #container" );

When this method executes, it retrieves the content of ajax/test.html, but then jQuery parses the returned document to find the element with an ID of container. This element, along with its contents, is inserted into the element with an ID of result, and the rest of the retrieved document is discarded.

If you're open to using jQuery:

<script type="text/javascript">
 function fncsave()
 {
    $('#<%= savebtn.ClientID %>').click();
 }
</script>

Also, if you are using .NET 4 or better you can make the ClientIDMode == static and simplify the code:

<script type="text/javascript">
 function fncsave()
 {
    $("#savebtn").click();
 }
</script>

Reference: MSDN Article for Control.ClientIDMode

Here I think it's worth mentioning SORT BY and ORDER BY both clauses and why they different,

SELECT * FROM <table_name> SORT BY <column_name> DESC LIMIT 2

If you are using SORT BY clause it sort data per reducer which means if you have more than one MapReduce task it will result partially ordered data. On the other hand, the ORDER BY clause will result in ordered data for the final Reduce task. To understand more please refer to this link.

SELECT * FROM <table_name> ORDER BY <column_name> DESC LIMIT 2

Note: Finally, Even though the accepted answer contains SORT BY clause, I mostly prefer to use ORDER BY clause for the general use case to avoid any data loss.

Recently I had to migrate some images from Docker registry (docker.mycompany.com) to Artifactory (docker.artifactory.mycompany.com)

docker pull docker.mycompany.com/something/redis:4.0.10
docker tag docker.mycompany.com/something/redis:4.0.10 docker.artifactory.mycompany.com/something/redis:4.0.10
docker push docker.artifactory.mycompany.com/something/redis:4.0.10

TextView t2 = (TextView) findViewById(R.id.textviewidname);
t2.setMovementMethod(LinkMovementMethod.getInstance());

and

<string name="google_stackoverflow"><a href="https://stackoverflow.com/questions/9852184/android-textview-hyperlink?rq=1">google stack overflow</a></string>

The link is, "Android: textview hyperlink"

and the tag is, "google stack overflow"

Define the first code block in your java and the second code block in your strings.xml file. Also, be sure to reference the id of the textView from your page layout in your java.

CHAR is a fixed-length data type that uses as much space as possible. So a:= a||'one '; will require more space than is available. Your problem can be reduced to the following example:

declare
  v_foo char(50);
begin
  v_foo := 'A';
  dbms_output.put_line('length of v_foo(A) = ' || length(v_foo));
  -- next line will raise:
  -- ORA-06502: PL/SQL: numeric or value error: character string buffer too small
  v_foo := v_foo || 'B';
  dbms_output.put_line('length of v_foo(AB) = ' || length(v_foo));  
end;
/

Never use char. For rationale check the following question (read also the links):

• Oracle datatype: Should I use VARCHAR2 or CHAR

If you want to know if the string is found in the array at all, try this function:

Function IsInArray(stringToBeFound As String, arr As Variant) As Boolean
  IsInArray = (UBound(Filter(arr, stringToBeFound)) > -1)
End Function

As SeanC points out, this must be a 1-D array.

Example:

Sub Test()
  Dim arr As Variant
  arr = Split("abc,def,ghi,jkl", ",")
  Debug.Print IsInArray("ghi", arr)
End Sub

(Below code updated based on comment from HansUp)

If you want the index of the matching element in the array, try this:

Function IsInArray(stringToBeFound As String, arr As Variant) As Long
  Dim i As Long
  ' default return value if value not found in array
  IsInArray = -1

  For i = LBound(arr) To UBound(arr)
    If StrComp(stringToBeFound, arr(i), vbTextCompare) = 0 Then
      IsInArray = i
      Exit For
    End If
  Next i
End Function

This also assumes a 1-D array. Keep in mind LBound and UBound are zero-based so an index of 2 means the third element, not the second.

Example:

Sub Test()
  Dim arr As Variant
  arr = Split("abc,def,ghi,jkl", ",")
  Debug.Print (IsInArray("ghi", arr) > -1)
End Sub

If you have a specific example in mind, please update your question with it, otherwise example code might not apply to your situation.

Applying a selector from the .nav-tabs seems to be working: See this demo.

$(document).ready(function(){
    activaTab('aaa');
});

function activaTab(tab){
    $('.nav-tabs a[href="#' + tab + '"]').tab('show');
};

I would prefer @codedme's answer, since if you know which tab you want prior to page load, you should probably change the page html and not use JS for this particular task.

I tweaked the demo for his answer, as well.

(If this is not working for you, please specify your setting - browser, environment, etc.)

You have to use XmlSerializer for XML serialization. Below is a sample snippet.

 XmlSerializer xsSubmit = new XmlSerializer(typeof(MyObject));
 var subReq = new MyObject();
 var xml = "";

 using(var sww = new StringWriter())
 {
     using(XmlWriter writer = XmlWriter.Create(sww))
     {
         xsSubmit.Serialize(writer, subReq);
         xml = sww.ToString(); // Your XML
     }
 }

I was about to ask the very same question. After searching a bit further and decyphering part of webpack's documentation I think that what you want is the output.library and output.libraryTarget in the webpack.config.js file.

For example:

js/index.js:

var foo = 3;
var bar = true;

webpack.config.js

module.exports = {
   ...
   entry: './js/index.js',
   output: {
      path: './www/js/',
      filename: 'index.js',
      library: 'myLibrary',
      libraryTarget: 'var'
   ...
}

Now if you link the generated www/js/index.js file in a html script tag you can access to myLibrary.foo from anywhere in your other scripts.

//Properly Formatted

<script type="text/Javascript">
  $(function ()    
{
    $('<div>').dialog({
        modal: true,
        open: function ()
        {
            $(this).load('mypage.html');
        },         
        height: 400,
        width: 600,
        title: 'Ajax Page'
    });
});

1. Open the "internet protocol properties" section on computer_2.
2. Enter the ip address (192.168.1.2) of computer_1 in "Preferred DNS server" text box and click ok and close the dialog box.

Now try to open the website again on computer_2.

find using an attribute in any tag

<th class="team" data-sort="team">Team</th>    
soup.find_all(attrs={"class": "team"}) 

<th data-sort="team">Team</th>  
soup.find_all(attrs={"data-sort": "team"}) 
 

A PivotTable might suit, though I am not quite certain of the layout of your data:

The bold numbers (one of each pair of duplicates) need not be shown as the field does not have to be subtotalled eg:

Include a few #ifndef name #define name #endif preprocessor that should solve your problem. The issue is it going from the header to the function then back to the header so it is redefining the class with all the preprocessor(#include) multiple times.

Have you tried logging in as the jenkins user?

Try this:

sudo -i -u jenkins #For RedHat you might have to do 'su' instead.
git clone [email protected]:your/repo.git

Often times you see failure if the host has not been added or authorized (hence I always manually login as hudson/jenkins for the first connection to github/bitbucket) but that link you included supposedly fixes that.

If the above doesn't work try recopying the key. Make sure its the pub key (ie id_rsa.pub). Maybe you missed some characters?

Every programming language has its own way of structuring the code.
whenever you write a block of code, it has to be organised in a way to be understood by everyone.

Usually used in conditional and classes and defining the definition.
It represents the parent, child and grandchild and further.

Example:

def example()
    print "name"
    print "my name"
example()

Here you can say example() is a parent and others are children.

Since none of the answers above actually explain what happened, I decided to chime in and bring some more details to this issue.

Yes, the solution is to run the MySQL Upgrade command, as follows: mysql_upgrade -u root -p --force, but what happened?

The root cause for this issue is the corruption of performance_schema, which can be caused by:

• Organic corruption (volumes going kaboom, engine bug, kernel driver issue etc)
• Corruption during mysql Patch (it is not unheard to have this happen during a mysql patch, specially for major version upgrades)
• A simple "drop database performance_schema" will obviously cause this issue, and it will present the same symptoms as if it was corrupted

This issue might have been present on your database even before the patch, but what happened on MySQL 5.7.8 specifically is that the flag show_compatibility_56 changed its default value from being turned ON by default, to OFF. This flag controls how the engine behaves on queries for setting and reading variables (session and global) on various MySQL Versions.

Because MySQL 5.7+ started to read and store these variables on performance_schema instead of on information_schema, this flag was introduced as ON for the first releases to reduce the blast radius of this change and to let users know about the change and get used to it.

OK, but why does the connection fail? Because depending on the driver you are using (and its configuration), it may end up running commands for every new connection initiated to the database (like show variables, for instance). Because one of these commands can try to access a corrupted performance_schema, the whole connection aborts before being fully initiated.

So, in summary, you may (it's impossible to tell now) have had performance_schema either missing or corrupted before patching. The patch to 5.7.8 then forced the engine to read your variables out of performance_schema (instead of information_schema, where it was reading it from because of the flag being turned ON). Since performance_schema was corrupted, the connections are failing.

Running MySQL upgrade is the best approach, despite the downtime. Turning the flag on is one option, but it comes with its own set of implications as it was pointed out on this thread already.

Both should work, but weight the consequences and know your choices :)

For the selected value: $(this).val()

If you need the selected option element, $("option:selected", this)

This is the simplest code to draw a rotated and scaled image:

function drawImage(ctx, image, x, y, w, h, degrees){
  ctx.save();
  ctx.translate(x+w/2, y+h/2);
  ctx.rotate(degrees*Math.PI/180.0);
  ctx.translate(-x-w/2, -y-h/2);
  ctx.drawImage(image, x, y, w, h);
  ctx.restore();
}

Theoretically, yes. Practice, not. Most kernels (incl. linux) doesn't allow you a second bind() to an already allocated port. It weren't a really big patch to make this allowed.

Conceptionally, we should differentiate between socket and port. Sockets are bidirectional communication endpoints, i.e. "things" where we can send and receive bytes. It is a conceptional thing, there is no such field in a packet header named "socket".

Port is an identifier which is capable to identify a socket. In case of the TCP, a port is a 16 bit integer, but there are other protocols as well (for example, on unix sockets, a "port" is essentially a string).

The main problem is the following: if an incoming packet arrives, the kernel can identify its socket by its destination port number. It is a most common way, but it is not the only possibility:

• Sockets can be identified by the destination IP of the incoming packets. This is the case, for example, if we have a server using two IPs simultanously. Then we can run, for example, different webservers on the same ports, but on the different IPs.
• Sockets can be identified by their source port and ip as well. This is the case in many load balancing configurations.

Because you are working on an application server, it will be able to do that.

Yes, you surely can... but it needs some work to make it work seamlessly. This is some code I came up with. Bear in mind that it does not use combobox's auto-complete features, and it might be quite slow if you use it to sift thru a lot of items...

    "Acworth","Ada","Ada","Adair","Adairs","Adair","Adak","Adalberta","Adamkrafft",
    "Adams"

};
public Form1()
{
    InitializeComponent();
}

private void comboBox1_TextChanged(object sender, EventArgs e)
{
    HandleTextChanged();
}

private void HandleTextChanged()
{
    var txt = comboBox1.Text;
    var list = from d in data
               where d.ToUpper().StartsWith(comboBox1.Text.ToUpper())
               select d;
    if (list.Count() > 0)
    {
        comboBox1.DataSource = list.ToList();
        //comboBox1.SelectedIndex = 0;
        var sText = comboBox1.Items[0].ToString();
        comboBox1.SelectionStart = txt.Length;
        comboBox1.SelectionLength = sText.Length - txt.Length;
        comboBox1.DroppedDown = true;
        return;
    }
    else
    {
        comboBox1.DroppedDown = false;
        comboBox1.SelectionStart = txt.Length;
    }
}

private void comboBox1_KeyUp(object sender, KeyEventArgs e)

    if (e.KeyCode == Keys.Back)

        int sStart = comboBox1.SelectionStart;

        {
            sStart--;
            if (sStart == 0)
            {
                comboBox1.Text = "";
            }
            else
            {
                comboBox1.Text = comboBox1.Text.Substring(0, sStart);

Have you got access to SSH?

You can use this command in shell to backup an entire database:

mysqldump -u [username] -p[password] [databasename] > [filename.sql]

This is actually one command followed by the > operator, which says, "take the output of the previous command and store it in this file."

Note: The lack of a space between -p and the mysql password is not a typo. However, if you leave the -p flag present, but the actual password blank then you will be prompted for your password. Sometimes this is recommended to keep passwords out of your bash history.

class CallByName():
    
    def method1(self):
        pass

    def method2(self):
        pass

    def method3(self):
        pass

    def get_method(self, method_name):
        method = getattr(self, method_name)
        return method()


callbyname = CallByName()
method1 = callbyname.get_method(method_name)

```

You could use the global application state.

Update:

Customize and then add this to your AndroidManifest.xml :

<application android:label="@string/app_name" android:debuggable="true" android:name=".CustomApplication"

And then have a class in your project like this :

package com.example;

import android.app.Application;

public class CustomApplication extends Application {
    public int someVariable = -1;
}

And because "It can be accessed via getApplication() from any Activity or Service", you use it like this:

CustomApplication application = (CustomApplication)getApplication();
application.someVariable = 123; 

Hope that helps.

reflect.DeepEqual is often incorrectly used to compare two like structs, as in your question.

cmp.Equal is a better tool for comparing structs.

To see why reflection is ill-advised, let's look at the documentation:

Struct values are deeply equal if their corresponding fields, both exported and unexported, are deeply equal.

....

numbers, bools, strings, and channels - are deeply equal if they are equal using Go's == operator.

If we compare two time.Time values of the same UTC time, t1 == t2 will be false if their metadata timezone is different.

go-cmp looks for the Equal() method and uses that to correctly compare times.

Example:

m1 := map[string]int{
    "a": 1,
    "b": 2,
}
m2 := map[string]int{
    "a": 1,
    "b": 2,
}
fmt.Println(cmp.Equal(m1, m2)) // will result in true

Should anyone face the same problem.

Do this: str.substring (...(trim()) ;

Hope it helps somebodies

There is clearly some confusion here as to what the preferred syntax for skipping a directory should be.

GNU Opinion

To ignore a directory and the files under it, use -prune

From the GNU find man page

Reasoning

-prune stops find from descending into a directory. Just specifying -not -path will still descend into the skipped directory, but -not -path will be false whenever find tests each file.

Issues with -prune

-prune does what it's intended to, but are still some things you have to take care of when using it.

1. find prints the pruned directory.

   • TRUE That's intended behavior, it just doesn't descend into it. To avoid printing the directory altogether, use a syntax that logically omits it.

2. -prune only works with -print and no other actions.

   • NOT TRUE. -prune works with any action except -delete. Why doesn't it work with delete? For -delete to work, find needs to traverse the directory in DFS order, since -deletewill first delete the leaves, then the parents of the leaves, etc... But for specifying -prune to make sense, find needs to hit a directory and stop descending it, which clearly makes no sense with -depth or -delete on.

Performance

I set up a simple test of the three top upvoted answers on this question (replaced -print with -exec bash -c 'echo $0' {} \; to show another action example). Results are below

----------------------------------------------
# of files/dirs in level one directories
.performance_test/prune_me     702702    
.performance_test/other        2         
----------------------------------------------

> find ".performance_test" -path ".performance_test/prune_me" -prune -o -exec bash -c 'echo "$0"' {} \;
.performance_test
.performance_test/other
.performance_test/other/foo
  [# of files] 3 [Runtime(ns)] 23513814

> find ".performance_test" -not \( -path ".performance_test/prune_me" -prune \) -exec bash -c 'echo "$0"' {} \;
.performance_test
.performance_test/other
.performance_test/other/foo
  [# of files] 3 [Runtime(ns)] 10670141

> find ".performance_test" -not -path ".performance_test/prune_me*" -exec bash -c 'echo "$0"' {} \;
.performance_test
.performance_test/other
.performance_test/other/foo
  [# of files] 3 [Runtime(ns)] 864843145

Conclusion

Both f10bit's syntax and Daniel C. Sobral's syntax took 10-25ms to run on average. GetFree's syntax, which doesn't use -prune, took 865ms. So, yes this is a rather extreme example, but if you care about run time and are doing anything remotely intensive you should use -prune.

Note Daniel C. Sobral's syntax performed the better of the two -prune syntaxes; but, I strongly suspect this is the result of some caching as switching the order in which the two ran resulted in the opposite result, while the non-prune version was always slowest.

You can use py2exe as already answered and use Cython to convert your key .py files in .pyc, C compiled files, like .dll in Windows and .so on Linux.

It is much harder to revert than common .pyo and .pyc files (and also gain in performance!).

The __init__ function is setting up all the member variables in the class. So once your bicluster is created you can access the member and get a value back:

mycluster = bicluster(...actual values go here...)
mycluster.left # returns the value passed in as 'left'

Check out the Python Docs for some info. You'll want to pick up an book on OO concepts to continue learning.

If (as I understand) you're trying to completely block inheritance in the web config of your child application, I suggest you to avoid using the tag in web.config. Instead create a new apppool and edit the applicationHost.config file (located in %WINDIR%\System32\inetsrv\Config and %WINDIR%\SysWOW64\inetsrv\config). You just have to find the entry for your apppool and add the attribute enableConfigurationOverride="false" like in the following example:

<add name="MyAppPool" autoStart="true" managedRuntimeVersion="v4.0" managedPipelineMode="Integrated" enableConfigurationOverride="false">
    <processModel identityType="NetworkService" />
</add>

This will avoid configuration inheritance in the applications served by MyAppPool.

Try using BigNumber in C# - Represents an arbitrarily large signed integer.

Program

using System.Numerics;
...
var bigNumber = BigInteger.Parse("837593454735734579347547357233757342857087879423437472347757234945743");
Console.WriteLine(bigNumber.ToString("X"));

Output

4F30DC39A5B10A824134D5B18EEA3707AC854EE565414ED2E498DCFDE1A15DA5FEB6074AE248458435BD417F06F674EB29A2CFECF

Possible Exceptions,

ArgumentNullException - value is null.

FormatException - value is not in the correct format.

Conclusion

You can convert string and store a value in BigNumber without constraints about the size of the number unless the string is empty and non-analphabets

A more powerful way of sorting a list of NSString to use things like NSNumericSearch :

NSArray *sortedArrayOfString = [arrayOfString sortedArrayUsingComparator:^NSComparisonResult(id obj1, id obj2) {
            return [(NSString *)obj1 compare:(NSString *)obj2 options:NSNumericSearch];
        }];

Combined with SortDescriptor, that would give something like :

NSSortDescriptor *sort = [NSSortDescriptor sortDescriptorWithKey:@"name" ascending:YES comparator:^NSComparisonResult(id obj1, id obj2) {
        return [(NSString *)obj1 compare:(NSString *)obj2 options:NSNumericSearch];
    }];
NSArray *sortedArray = [anArray sortedArrayUsingDescriptors:[NSArray arrayWithObject:sort]];

If you are defining a constant to be shared among all the instances of the class, use static const. If the constant is specific to each instance, just use const (but note that all constructors of the class must initialize this const member variable in the initialization list).

It is a bit of hack but will do the task.

Function equalsIgnoreCase(str1 As String, str2 As String) As Boolean
    equalsIgnoreCase = LCase(str1) = LCase(str2)
End Function

A Date object's underlying value is actually in UTC. To prove this, notice that if you type new Date(0) you'll see something like: Wed Dec 31 1969 16:00:00 GMT-0800 (PST). 0 is treated as 0 in GMT, but .toString() method shows the local time.

Big note, UTC stands for Universal time code. The current time right now in 2 different places is the same UTC, but the output can be formatted differently.

What we need here is some formatting

var _date = new Date(1270544790922); 
// outputs > "Tue Apr 06 2010 02:06:30 GMT-0700 (PDT)", for me
_date.toLocaleString('fi-FI', { timeZone: 'Europe/Helsinki' });
// outputs > "6.4.2010 klo 12.06.30"
_date.toLocaleString('en-US', { timeZone: 'Europe/Helsinki' });
// outputs > "4/6/2010, 12:06:30 PM"

This works but.... you can't really use any of the other date methods for your purposes since they describe the user's timezone. What you want is a date object that's related to the Helsinki timezone. Your options at this point are to use some 3rd party library (I recommend this), or hack-up the date object so you can use most of it's methods.

Option 1 - a 3rd party like moment-timezone

moment(1270544790922).tz('Europe/Helsinki').format('YYYY-MM-DD HH:mm:ss')
// outputs > 2010-04-06 12:06:30
moment(1270544790922).tz('Europe/Helsinki').hour()
// outputs > 12

This looks a lot more elegant than what we're about to do next.

Option 2 - Hack up the date object

var currentHelsinkiHoursOffset = 2; // sometimes it is 3
var date = new Date(1270544790922);
var helsenkiOffset = currentHelsinkiHoursOffset*60*60000;
var userOffset = _date.getTimezoneOffset()*60000; // [min*60000 = ms]
var helsenkiTime = new Date(date.getTime()+ helsenkiOffset + userOffset);
// Outputs > Tue Apr 06 2010 12:06:30 GMT-0700 (PDT)

It still thinks it's GMT-0700 (PDT), but if you don't stare too hard you may be able to mistake that for a date object that's useful for your purposes.

I conveniently skipped a part. You need to be able to define currentHelsinkiOffset. If you can use date.getTimezoneOffset() on the server side, or just use some if statements to describe when the time zone changes will occur, that should solve your problem.

Conclusion - I think especially for this purpose you should use a date library like moment-timezone.

While Docker for Windows is perfectly able to run Linux containers, the converse, while theoretically possible, is not implemented due to practical reasons.

The most obvious one is, while Docker for Windows can run a Linux VM freely, Docker for Linux would require a Windows license in order to run it inside a VM.

Also, Linux is completely customizable, so the Linux VM used by Docker for Windows has been stripped down to just a few MB, containing only the bare minimum needed to run the containers, while the smallest Windows distribution available is about 1.5 GB. It may not be an impracticable size, but it is much more cumbersome than the Linux on Windows counterpart.

While it is certainly possible for someone to sell a Docker for Linux variation bundled with a Windows license and ready to run Windows containers under Linux (and I don't know if such product exists), the bottom line is that you can't avoid paying Windows vendor lock-in price: both in money and storage space.

My Problem: "please select Android SDK", But everything is okey :( -> I think one of IntelliJ file was crashed (after blue screen of death)

My resolution:

File -> Settings -> Android SDK -> Android SDK Location Edit -> Next, Next (Android SDK is up to date.), Finished

... and crashed file was repaired!

Aborting a Task is easily possible if you capture the thread in which the task is running in. Here is an example code to demonstrate this:

void Main()
{
    Thread thread = null;

    Task t = Task.Run(() => 
    {
        //Capture the thread
        thread = Thread.CurrentThread;

        //Simulate work (usually from 3rd party code)
        Thread.Sleep(1000);

        //If you comment out thread.Abort(), then this will be displayed
        Console.WriteLine("Task finished!");
    });

    //This is needed in the example to avoid thread being still NULL
    Thread.Sleep(10);

    //Cancel the task by aborting the thread
    thread.Abort();
}

I used Task.Run() to show the most common use-case for this - using the comfort of Tasks with old single-threaded code, which does not use the CancellationTokenSource class to determine if it should be canceled or not.

In bash, use $OSTYPE and $HOSTTYPE, as documented; this is what I do. If that is not enough, and if even uname or uname -a (or other appropriate options) does not give enough information, there’s always the config.guess script from the GNU project, made exactly for this purpose.

Lets do some experimentation, to see how we could get/interpret the length of different dict/array values in a dict.

create our test dict, see list and dict comprehensions:

>>> my_dict = {x:[i for i in range(x)] for x in range(4)}
>>> my_dict
{0: [], 1: [0], 2: [0, 1], 3: [0, 1, 2]}

Get the length of the value of a specific key:

>>> my_dict[3]
[0, 1, 2]
>>> len(my_dict[3])
3

Get a dict of the lengths of the values of each key:

>>> key_to_value_lengths = {k:len(v) for k, v in my_dict.items()}
{0: 0, 1: 1, 2: 2, 3: 3}
>>> key_to_value_lengths[2]
2

Get the sum of the lengths of all values in the dict:

>>> [len(x) for x in my_dict.values()]
[0, 1, 2, 3]
>>> sum([len(x) for x in my_dict.values()])
6

Arrays are objects and they have a length field.

String[] haha = {"olle", "bulle"};

haha.length would be 2

PROBLEM RESOLVED

In my case the problem was that I do the ajax call (with $.ajax, $.get or $.getJSON methods from jQuery) with full path in the url param:

url: "http://mydomain.com/site/cgi-bin/serverApp.php"

But the correct way is to pass the value of url as:

url: "site/cgi-bin/serverApp.php"

Some browser don't conflict and make no distiction between one text or another, but in Firefox 3.6 for Mac OS take this full path as "cross site scripting"... another thing, in the same browser there is a distinction between:

http://mydomain.com/site/index.html

And put

http://www.mydomain.com/site/index.html

In fact it is the correct point view, but most implementations make no distinction, so the solution was to remove all the text that specify the full path to the script in the methods that do the ajax request AND.... remove any BASE tag in the index.html file

base href="http://mydomain.com/" <--- bad idea, remove it!

If you don't remove it, this version of browser for this system may take your ajax request like if it is a cross site request!

I have the same problem but only on the Mac OS machine. The problem is that Firefox treat the ajax response as an "cross site" call, in any other machine/browser it works fine. I didn't found any help about this (I think that is a firefox implementation issue), but I'm going to prove the next code at the server side:

header('Content-type: application/json');

to ensure that browser get the data as "json data" ...

The CLI's webpack config can now be ejected. Check Anton Nikiforov's answer.

outdated:

You can hack the config template in angular-cli/addon/ng2/models. There's no official way to modify the webpack config as of now.

There's a closed "wont-fix" issue on github about this: https://github.com/angular/angular-cli/issues/1656

It's because you're missing position:relative; on #contentframe

<div id="contentframe" style="position:relative; top: 160px; left: 0px;">

position:absolute; positions itself against the closest ancestor that has a position that is not static. Since the default is static that is what was causing your issue.

For renaming the columns here is the simple one which will work for both Default(0,1,2,etc;) and existing columns but not much useful for a larger data sets(having many columns).

For a larger data set we can slice the columns that we need and apply the below code:

df.columns = ['new_name','new_name1','old_name']

simple, try this

position: fixed;
width: 500px;
height: 300px;
top: calc(50% - 150px);
left: calc(50% - 250px);
background-color: red;

For Option 1 used as the placeholder:

select:invalid { color:grey; }

All other options:

select:valid { color:black; }

One way to do this would be to override Equals() on each type involved. For example, your top level object would override Equals() to call the Equals() method of all 5 child objects. Those objects should all override Equals() as well, assuming they are custom objects, and so on until the entire hierarchy could be compared by just performing an equality check on the top level objects.

You also encounter this if you run an Application on a Scheduled Task in Non-Interactive mode.

As soon as you show a Dialog it throws the error:

Showing a modal dialog box or form when the application is not running in UserInteractive mode is not a valid operation. Specify the ServiceNotification or DefaultDesktopOnly style to display a notification from a service application.

You can see its a MessageBox causing the problem in the stack trace:

at System.Windows.Forms.MessageBox.ShowCore(IWin32Window owner, String text, String caption, MessageBoxButtons buttons, MessageBoxIcon icon,  MessageBoxDefaultButton defaultButton, MessageBoxOptions options, Boolean showHelp)  

Solution

If you're running your app on a Scheduled Task send an email instead of showing a Dialog.

You need a regular expression for this. Look here. If you are using .net Framework4.5 then you can also use this. As it is built in .net Framework 4.5. Example

[EmailAddress(ErrorMessage = "Invalid Email Address")]
public string Email { get; set; }

I used the svn2git script and works like a charm.

Use #include <windows.h> instead of #include <windef.h>.

From the windows.h wikipedia page:

There are a number of child header files that are automatically included with windows.h. Many of these files cannot simply be included by themselves (they are not self-contained), because of dependencies.

windef.h is one of the files automatically included with windows.h.

UPDATE (GEOCODE MULTIPLE ADDRESSES)

Here's the working Example Geocoding with multiple addresses.

 <script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=false">
 </script> 
 <script type="text/javascript">
  var delay = 100;
  var infowindow = new google.maps.InfoWindow();
  var latlng = new google.maps.LatLng(21.0000, 78.0000);
  var mapOptions = {
    zoom: 5,
    center: latlng,
    mapTypeId: google.maps.MapTypeId.ROADMAP
  }
  var geocoder = new google.maps.Geocoder(); 
  var map = new google.maps.Map(document.getElementById("map"), mapOptions);
  var bounds = new google.maps.LatLngBounds();

  function geocodeAddress(address, next) {
    geocoder.geocode({address:address}, function (results,status)
      { 
         if (status == google.maps.GeocoderStatus.OK) {
          var p = results[0].geometry.location;
          var lat=p.lat();
          var lng=p.lng();
          createMarker(address,lat,lng);
        }
        else {
           if (status == google.maps.GeocoderStatus.OVER_QUERY_LIMIT) {
            nextAddress--;
            delay++;
          } else {
                        }   
        }
        next();
      }
    );
  }
 function createMarker(add,lat,lng) {
   var contentString = add;
   var marker = new google.maps.Marker({
     position: new google.maps.LatLng(lat,lng),
     map: map,
           });

  google.maps.event.addListener(marker, 'click', function() {
     infowindow.setContent(contentString); 
     infowindow.open(map,marker);
   });

   bounds.extend(marker.position);

 }
  var locations = [
           'New Delhi, India',
           'Mumbai, India',
           'Bangaluru, Karnataka, India',
           'Hyderabad, Ahemdabad, India',
           'Gurgaon, Haryana, India',
           'Cannaught Place, New Delhi, India',
           'Bandra, Mumbai, India',
           'Nainital, Uttranchal, India',
           'Guwahati, India',
           'West Bengal, India',
           'Jammu, India',
           'Kanyakumari, India',
           'Kerala, India',
           'Himachal Pradesh, India',
           'Shillong, India',
           'Chandigarh, India',
           'Dwarka, New Delhi, India',
           'Pune, India',
           'Indore, India',
           'Orissa, India',
           'Shimla, India',
           'Gujarat, India'
  ];
  var nextAddress = 0;
  function theNext() {
    if (nextAddress < locations.length) {
      setTimeout('geocodeAddress("'+locations[nextAddress]+'",theNext)', delay);
      nextAddress++;
    } else {
      map.fitBounds(bounds);
    }
  }
  theNext();

</script>

As we can resolve this issue with setTimeout() function.

Still we should not geocode known locations every time you load your page as said by @geocodezip

Another alternatives of these are explained very well in the following links:

How To Avoid GoogleMap Geocode Limit!

Geocode Multiple Addresses Tutorial By Mike Williams

Example by Google Developers

Ruby 1.9 has removed the current directory from the load path, and so you will need to do a relative require on this file, as David Grayson says:

require_relative 'tokenizer'

There's no need to suffix it with .rb, as Ruby's smart enough to know that's what you mean anyway.

you can return a FileResult from your MVC action.

*********************MVC action************

    public FileResult OpenPDF(parameters)
    {
       //code to fetch your pdf byte array
       return File(pdfBytes, "application/pdf");
    }

**************js**************

Use formpost to post your data to action

    var inputTag = '<input name="paramName" type="text" value="' + payloadString + '">';
    var form = document.createElement("form");
    jQuery(form).attr("id", "pdf-form").attr("name", "pdf-form").attr("class", "pdf-form").attr("target", "_blank");
    jQuery(form).attr("action", "/Controller/OpenPDF").attr("method", "post").attr("enctype", "multipart/form-data");
    jQuery(form).append(inputTag);
    document.body.appendChild(form);
    form.submit();
    document.body.removeChild(form);
    return false;

You need to create a form to post your data, append it your dom, post your data and remove the form your document body.

However, form post wouldn't post data to new tab only on EDGE browser. But a get request works as it's just opening new tab with a url containing query string for your action parameters.

overthink suggested using the setup in the pom:

<project>
...
<build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-eclipse-plugin</artifactId>
            <configuration>
                <downloadSources>true</downloadSources>
                <downloadJavadocs>true</downloadJavadocs>
                ... other stuff ...
            </configuration>
        </plugin>
    </plgins>
</build>
...

First i thought this still won't attach the javadoc and sources (as i tried unsuccessfully with that -DdownloadSources option before).

But surprise - the .classpath file IS getting its sources and javadoc attached when using the POM variant!

A bit of pandas code:

import pandas

def to_millis(dt):
    return int(pandas.to_datetime(dt).value / 1000000)

i couldn't change the permissions on the sharepoint i'm using but got a round it by uploading .url files with the drag and drop multiple files uploader.

Using the normal upload didn't work because they are intepreted by the file open dialog when you try to open them singly so it just tries to open the target not the .url file.

.url files can be made by saving a favourite with internet exploiter.

Personally, I think the concatenation is the better solution. The generic implementation would be

entity shifter is
    generic (
        REGSIZE  : integer := 8);
    port(
        clk      : in  str_logic;
        Data_in  : in  std_logic;
        Data_out : out std_logic(REGSIZE-1 downto 0);
end shifter ;

architecture bhv of shifter is
    signal shift_reg : std_logic_vector(REGSIZE-1 downto 0) := (others<='0');
begin
    process (clk) begin
        if rising_edge(clk) then
            shift_reg <= shift_reg(REGSIZE-2 downto 0) & Data_in;
        end if;
    end process;
end bhv;
Data_out <= shift_reg;

Both will implement as shift registers. If you find yourself in need of more shift registers than you are willing to spend resources on (EG dividing 1000 numbers by 4) you might consider using a BRAM to store the values and a single shift register to contain "indices" that result in the correct shift of all the numbers.

You need the /g for global matching

replace(/\n/g, "<br />");

This works for me for \n - see this answer if you might have \r\n

NOTE: The dupe is the most complete answer for any combination of \r\n, \r or \n

var messagetoSend = document.getElementById('x').value.replace(/\n/g, "<br />");_x000D_
console.log(messagetoSend);

<textarea id="x" rows="9">_x000D_
    Line 1_x000D_
    _x000D_
    _x000D_
    Line 2_x000D_
    _x000D_
    _x000D_
    _x000D_
    _x000D_
    Line 3_x000D_
</textarea>

UPDATE

It seems some visitors of this question have text with the breaklines escaped as

some text\r\nover more than one line"

In that case you need to escape the slashes:

replace(/\\r\\n/g, "<br />");

NOTE: All browsers will ignore \r in a string when rendering.

Type

git push

from the command line inside the repository directory

using ylim() might be the best approach for your purpose:

xValues = list(range(10))
quads = [x** 2 for x in xValues]
plt.ylim(max(quads), 0)
plt.plot(xValues, quads)

will result:

I think you may have missed this part in the tutorial:

Instead of referencing System.Data and System.Data.SqlClient you need to grab from Nuget:

System.Data.Common and System.Data.SqlClient.

Currently this creates dependency in project.json –> aspnetcore50 section to these two libraries.

"aspnetcore50": {
       "dependencies": {
           "System.Runtime": "4.0.20-beta-22523",
           "System.Data.Common": "4.0.0.0-beta-22605",
           "System.Data.SqlClient": "4.0.0.0-beta-22605"
       }
}

Try getting System.Data.Common and System.Data.SqlClient via Nuget and see if this adds the above dependencies for you, but in a nutshell you are missing System.Runtime.

Edit: As per Mozarts answer, if you are using .NET Core 3+, reference Microsoft.Data.SqlClient instead.

Please refer the below steps:

1. First create a page SessionClear.aspx and write the code to clear session

2. Then add following JavaScript code in your page or Master Page:

   <script language="javascript" type="text/javascript">
       var isClose = false;
   
       //this code will handle the F5 or Ctrl+F5 key
       //need to handle more cases like ctrl+R whose codes are not listed here
       document.onkeydown = checkKeycode
       function checkKeycode(e) {
       var keycode;
       if (window.event)
       keycode = window.event.keyCode;
       else if (e)
       keycode = e.which;
       if(keycode == 116)
       {
       isClose = true;
       }
       }
       function somefunction()
       {
       isClose = true;
       }
   
       //<![CDATA[
   
           function bodyUnload() {
   
         if(!isClose)
         {
                 var request = GetRequest();
                 request.open("GET", "SessionClear.aspx", true);
                 request.send();
         }
           }
           function GetRequest() {
               var request = null;
               if (window.XMLHttpRequest) {
                   //incase of IE7,FF, Opera and Safari browser
                   request = new XMLHttpRequest();
               }
               else {
                   //for old browser like IE 6.x and IE 5.x
                   request = new ActiveXObject('MSXML2.XMLHTTP.3.0');
               }
               return request;
           } 
       //]]>
   </script>
   

3. Add the following code in the body tag of master page.

   <body onbeforeunload="bodyUnload();" onmousedown="somefunction()">
   

I solved this issue by redirecting the user to the FQDN of the server hosting the intranet.

IE probably uses the world's worst algorithm for detecting "intranet" sites ... indeed, specifying server.domain.tld solves the problem for me.

Yes, you read that correctly, IE detects intranet sites not by private IP address, like any dev who has heard of TCP/IP would do, no, by the "host" part of the URL, if it has no domain part, must be internal.

Scary to know the IE devs do not understand the most basic TCP/IP concepts.

Note that this was at a BIG enterprise customer, getting them to change GPO for you is like trying to move the Alps east by 4 meters, not gonna happen.

You can use a shortcut that links to the batch file. Just go into properties for the shortcut and select advanced, then "run as administrator".

Then just make the batch file hidden, and run the shortcut.

This way, you can even set your own icon for the shortcut.

Expanding on Chris' answer. I managed to reverse engineer the token generation process.

The token for the request is based on the text and a global TKK variable set in the page script. These are hashed in JavaScript thus resulting in the tk param.

Somewhere in the page script you will find something like this:

TKK='403413';

This is the amount of hours passed since epoch.

The text is pumped in the following function (somewhat deobfuscated):

var query = "Hello person";_x000D_
var cM = function(a) {_x000D_
    return function() {_x000D_
        return a_x000D_
    }_x000D_
};_x000D_

I managed to successfully port this to python in my fork of gTTS, so I know this works.

Edit: By now the token generation code used by gTTS has been moved into gTTS-token.

Edit 2: Google has changed the API (somewhere around 2016-05-10), this method requires some modification. I'm currently working on this. In the meantime changing the client to tw-ob seems to work.

Edit 3:

The changes are minor, yet annoying to say the least. The TKK now has two parts. Looking something like 406986.2817744745. As you can see the first part has remained the same. The second part is the sum of two seemingly random numbers. TKK=eval('((function(){var a\x3d2680116022;var b\x3d137628723;return 406986+\x27.\x27+(a+b)})())'); Here \x3d means = and \x27 is '. Both a and b change every UTC minute. At one of the final steps in the algorithm the token is XORed by the second part.

The new token generation code is:

Of course I can't generate a valid url anymore, since I don't know how a and b are generated.

Here is an answer based on that by Anubis (which is a better approach as it doesn't modify the headers for every request) but which is more equivalent to the code in the original question:

using Newtonsoft.Json;
...

var client = new HttpClient();
var httpRequestMessage = new HttpRequestMessage
    {
        Method = HttpMethod.Post,
        RequestUri = new Uri("https://api.clickatell.com/rest/message"),
        Headers = { 
            { HttpRequestHeader.Authorization.ToString(), "Bearer xxxxxxxxxxxxxxxxxxx" },
            { HttpRequestHeader.Accept.ToString(), "application/json" },
            { "X-Version", "1" }
        },
        Content = new StringContent(JsonConvert.SerializeObject(svm))
    };

var response = client.SendAsync(httpRequestMessage).Result;

SELECT
   logcount, logUserID, maxlogtm,
   DATEDIFF(day, maxlogtm, GETDATE()) AS daysdiff
FROM statslogsummary
WHERE ( DATEDIFF(day, maxlogtm, GETDATE() > 120)

Normally you can't refer to field aliases in the WHERE clause. (Think of it as the entire SELECT including aliases, is applied after the WHERE clause.)

But, as mentioned in other answers, you can force SQL to treat SELECT to be handled before the WHERE clause. This is usually done with parenthesis to force logical order of operation or with a Common Table Expression (CTE):

Parenthesis/Subselect:

SELECT
   *
FROM
(
   SELECT
      logcount, logUserID, maxlogtm,
      DATEDIFF(day, maxlogtm, GETDATE()) AS daysdiff
   FROM statslogsummary   
) as innerTable
WHERE daysdiff > 120

Or see Adam's answer for a CTE version of the same.

#fullDiv {
  position: absolute;
  margin: 0;
  padding: 0;
  left: 0;
  top: 0;
  bottom: 0;
  right: 0;
  overflow: hidden; /* or auto or scroll */
}

Try this

If @NewStatus  = 'InOffice' 
BEGIN
     Update tblEmployee set InOffice = -1 where EmpID = @EmpID
END
Else If @NewStatus  = 'OutOffice'
BEGIN
    Update tblEmployee set InOffice = -1 where EmpID = @EmpID
END
Else If @NewStatus  = 'Home'
BEGIN
    Update tblEmployee set Home = -1 where EmpID = @EmpID
END

Consider adding the switch /D_USE_MATH_DEFINES to your compilation command line, or to define the macro in the project settings. This will drag the symbol to all reachable dark corners of include and source files leaving your source clean for multiple platforms. If you set it globally for the whole project, you will not forget it later in a new file(s).

I think of Divide & Conquer as an recursive approach and Dynamic Programming as table filling.

For example, Merge Sort is a Divide & Conquer algorithm, as in each step, you split the array into two halves, recursively call Merge Sort upon the two halves and then merge them.

Knapsack is a Dynamic Programming algorithm as you are filling a table representing optimal solutions to subproblems of the overall knapsack. Each entry in the table corresponds to the maximum value you can carry in a bag of weight w given items 1-j.

This issue should now be fixed. Update rubygems (gem update --system), make sure openssl is at the latest version on your OS, or try these tips of it's still not working: http://railsapps.github.com/openssl-certificate-verify-failed.html

assert will terminate the program (usually with a message quoting the assert statement) if its argument turns out to be false. It's commonly used during debugging to make the program fail more obviously if an unexpected condition occurs.

For example:

assert(length >= 0);  // die if length is negative.

You can also add a more informative message to be displayed if it fails like so:

assert(length >= 0 && "Whoops, length can't possibly be negative! (didn't we just check 10 lines ago?) Tell jsmith");

Or else like this:

assert(("Length can't possibly be negative! Tell jsmith", length >= 0));

When you're doing a release (non-debug) build, you can also remove the overhead of evaluating assert statements by defining the NDEBUG macro, usually with a compiler switch. The corollary of this is that your program should never rely on the assert macro running.

// BAD
assert(x++);

// GOOD
assert(x);    
x++;

// Watch out! Depends on the function:
assert(foo());

// Here's a safer way:
int ret = foo();
assert(ret);

From the combination of the program calling abort() and not being guaranteed to do anything, asserts should only be used to test things that the developer has assumed rather than, for example, the user entering a number rather than a letter (which should be handled by other means).

The $ symbol simply invokes the jQuery library's selector functionality. So $("#Text") returns the jQuery object for the Text div which can then be modified.

This is my solution in ES6 to create a string contraining the concatenated text of all childnodes (recursive). Note that is also visit the shdowroot of childnodes.

function text_from(node) {
    const extract = (node) => [...node.childNodes].reduce(
        (acc, childnode) => [
            ...acc,
            childnode.nodeType === Node.TEXT_NODE ? childnode.textContent.trim() : '',
            ...extract(childnode),
            ...(childnode.shadowRoot ? extract(childnode.shadowRoot) : [])],
        []);

    return extract(node).filter(text => text.length).join('\n');
}

This solution was inspired by the solution of https://stackoverflow.com/a/41051238./1300775.

Here is a combination of the answer by @Mohsenasm and a comment from @Ghigo adopted to Swift

extension UIView {
    var globalFrame: CGRect? {
        let rootView = UIApplication.shared.keyWindow?.rootViewController?.view
        return self.superview?.convert(self.frame, to: rootView)
    }
}

Because you have used absolute positioning, and specified a top percentage, only margin-top will affect the location of your .item object. If instead you positioned it using bottom: 50%, then you'd need margin-bottom -8px to centre it, and margin-top would have no effect.

Margin affects the boundaries of an element in terms of positioning it, either absolutely as in your case, or relative to neighbouring elements. Imagine that margin is the foundations of your element on which it sits. They are typically the same size as it, but can be made larger or smaller on any or all of the four edges.

Your CSS tells the browser to position the top of your element the margin at a point 50% of the way down the page. However, as all elements are not a single pixel, the browser needs to know which part of it to line up 50% of the way down the page. For lining up the top of the element, it uses the top margin. By default this is in line with the top of the element, but you can alter it with CSS.

In your case, top 50% would result in the top of the element starting in the middle of the page. By applying a negative top margin, the browser uses the point 8px into the element from the top (ie the line across the middle of it) as the place to position at 50%.

If you apply a positive margin to the bottom, this extends the line the browser uses to position the bottom out away from the element itself, giving a gap between it and any adjacent element below, or affecting where it is placed absolutely if positioning based on the bottom.

Let me quickly summarize this for reference:

• error_reporting() adapts the currently active setting for the default error handler.

• Editing the error reporting ini options also changes the defaults.

  • Here it's imperative to edit the correct php.ini version - it's typically /etc/php5/fpm/php.ini on modern servers, /etc/php5/mod_php/php.ini alternatively; while the CLI version has a distinct one.

  • Alternatively you can use depending on SAPI:

    • mod_php: .htaccess with php_flag options
    • FastCGI: commonly a local php.ini
    • And with PHP above 5.3 also a .user.ini
      
      

  • Restarting the webserver as usual.

If your code is unwieldy and somehow resets these options elsewhere at runtime, then an alternative and quick way is to define a custom error handler that just slurps all notices/warnings/errors up:

set_error_handler(function(){});

Again, this is not advisable, just an alternative.

Check that right version is referenced in your project. E.g. the dll it is complaining about, could be from an older version and that's why there could be a version mismatch.

You can try this function

/**
 * Gets the request parameter.
 *
 * @param      string  $key      The query parameter
 * @param      string  $default  The default value to return if not found
 *
 * @return     string  The request parameter.
 */

function get_request_parameter( $key, $default = '' ) {
    // If not request set
    if ( ! isset( $_REQUEST[ $key ] ) || empty( $_REQUEST[ $key ] ) ) {
        return $default;
    }

    // Set so process it
    return strip_tags( (string) wp_unslash( $_REQUEST[ $key ] ) );
}

Here is what is happening in the function

Here three things are happening.

• First we check if the request key is present or not. If not, then just return a default value.
• If it is set, then we first remove slashes by doing wp_unslash. Read here why it is better than stripslashes_deep.
• Then we sanitize the value by doing a simple strip_tags. If you expect rich text from parameter, then run it through wp_kses or similar functions.

All of this information plus more info on the thinking behind the function can be found on this link https://www.intechgrity.com/correct-way-get-url-parameter-values-wordpress/

For Windows 10 if you want use pip in normal cmd, not only in Anaconda prompt. you need add 3 environment paths. like the followings:

D:\Anaconda3 
D:\Anaconda3\Scripts
D:\Anaconda3\Library\bin 

most people only add D:\Anaconda3\Scripts

In Visual Studio Express 2013 for web it's hidden away in View > Other Windows > Toolbox.

Just weighing in here with a nice solution I have been using. This is similar to Lucky Soni's solution above in that it supports aggregation, but doesn't require hard coding of the field names.

cursor = db.<collection_name>.<my_query_with_aggregation>;

headerPrinted = false;
while (cursor.hasNext()) {
    item = cursor.next();
    
    if (!headerPrinted) {
        print(Object.keys(item).join(','));
        headerPrinted = true;
    }

    line = Object
        .keys(item)
        .map(function(prop) {
            return '"' + item[prop] + '"';
        })
        .join(',');
    print(line);
}

Save this as a .js file, in this case we'll call it example.js and run it with the mongo command line like so:

mongo <database_name> example.js --quiet > example.csv

SQL NULL's special, and you have to do WHERE field IS NULL, as NULL cannot be equal to anything,

including itself (ie: NULL = NULL is always false).

See Rule 3 https://en.wikipedia.org/wiki/Codd%27s_12_rules

Check out this great blog post by John Atten: ASP.NET Identity 2.0: Customizing Users and Roles

It has great step-by-step info on the whole process. Go read it : )

Here are some of the basics.

Extend the default ApplicationUser class by adding new properties (i.e.- Address, City, State, etc.):

public class ApplicationUser : IdentityUser
{
    public async Task<ClaimsIdentity> 
    GenerateUserIdentityAsync(UserManager<ApplicationUser> manager)
    {
        var userIdentity = await manager.CreateIdentityAsync(this,  DefaultAuthenticationTypes.ApplicationCookie);
        return userIdentity;
    }
    public string Address { get; set; }
    public string City { get; set; }
    public string State { get; set; }

    // Use a sensible display name for views:
    [Display(Name = "Postal Code")]
    public string PostalCode { get; set; }

    // Concatenate the address info for display in tables and such:
    public string DisplayAddress
    {
        get
        {
            string dspAddress = string.IsNullOrWhiteSpace(this.Address) ? "" : this.Address;
            string dspCity = string.IsNullOrWhiteSpace(this.City) ? "" : this.City;
            string dspState = string.IsNullOrWhiteSpace(this.State) ? "" : this.State;
            string dspPostalCode = string.IsNullOrWhiteSpace(this.PostalCode) ? "" : this.PostalCode;

            return string.Format("{0} {1} {2} {3}", dspAddress, dspCity, dspState, dspPostalCode);
        }
    }

Then you add your new properties to your RegisterViewModel.

    // Add the new address properties:
    public string Address { get; set; }
    public string City { get; set; }
    public string State { get; set; }

Then update the Register View to include the new properties.

    <div class="form-group">
        @Html.LabelFor(m => m.Address, new { @class = "col-md-2 control-label" })
        <div class="col-md-10">
            @Html.TextBoxFor(m => m.Address, new { @class = "form-control" })
        </div>
    </div>

Then update the Register() method on AccountController with the new properties.

    // Add the Address properties:
    user.Address = model.Address;
    user.City = model.City;
    user.State = model.State;
    user.PostalCode = model.PostalCode;

I tested this and it kinda works out :

exec(open('filename').read())  # Don't forget to put the filename between ' '

From the Javadocs for setDisplayOrientation(int) (Requires API level 9):

 public static void setCameraDisplayOrientation(Activity activity,
         int cameraId, android.hardware.Camera camera) {
     android.hardware.Camera.CameraInfo info =
             new android.hardware.Camera.CameraInfo();
     android.hardware.Camera.getCameraInfo(cameraId, info);
     int rotation = activity.getWindowManager().getDefaultDisplay()
             .getRotation();
     int degrees = 0;
     switch (rotation) {
         case Surface.ROTATION_0: degrees = 0; break;
         case Surface.ROTATION_90: degrees = 90; break;
         case Surface.ROTATION_180: degrees = 180; break;
         case Surface.ROTATION_270: degrees = 270; break;
     }

     int result;
     if (info.facing == Camera.CameraInfo.CAMERA_FACING_FRONT) {
         result = (info.orientation + degrees) % 360;
         result = (360 - result) % 360;  // compensate the mirror
     } else {  // back-facing
         result = (info.orientation - degrees + 360) % 360;
     }
     camera.setDisplayOrientation(result);
 }

Many of Microsoft's secure functions, including fopen_s(), are part of C11, so they should be portable now. You should realize that the secure functions differ in exception behaviors and sometimes in return values. Additionally you need to be aware that while these functions are standardized, it's an optional part of the standard (Annex K) that at least glibc (default on Linux) and FreeBSD's libc don't implement.

However, I fought this problem for a few years. I posted a larger set of conversion macros here., For your immediate problem, put the following code in an include file, and include it in your source code:

#pragma once
#if !defined(FCN_S_MACROS_H)
   #define   FCN_S_MACROS_H

   #include <cstdio>
   #include <string> // Need this for _stricmp
   using namespace std;

   // _MSC_VER = 1400 is MSVC 2005. _MSC_VER = 1600 (MSVC 2010) was the current
   // value when I wrote (some of) these macros.

   #if (defined(_MSC_VER) && (_MSC_VER >= 1400) )

      inline extern
      FILE*   fcnSMacro_fopen_s(char *fname, char *mode)
      {  FILE *fptr;
         fopen_s(&fptr, fname, mode);
         return fptr;
      }
      #define fopen(fname, mode)            fcnSMacro_fopen_s((fname), (mode))

   #else
      #define fopen_s(fp, fmt, mode)        *(fp)=fopen( (fmt), (mode))

   #endif //_MSC_VER

#endif // FCN_S_MACROS_H

Of course this approach does not implement the expected exception behavior.

For me, the latest pip (1.5.6) works fine with the insecure nltk package if you just tell it not to be so picky about security:

pip install --upgrade --force-reinstall --allow-all-external --allow-unverified ntlk nltk

It's a linker error. ld is the linker, so if you get an error message ending with "ld returned 1 exit status", that tells you that it's a linker error.

The error message tells you that none of the object files you're linking against contains a definition for avergecolumns. The reason for that is that the function you've defined is called averagecolumns (in other words: you misspelled the function name when calling the function (and presumably in the header file as well - otherwise you'd have gotten a different error at compile time)).

The logic is simple. setOnClickListener belongs to step 2.

1. You create the button
2. You create an instance of OnClickListener* like it's done in that example and override the onClick-method.
3. You assign that OnClickListener to that button using btn.setOnClickListener(myOnClickListener); in your fragments/activities onCreate-method.
4. When the user clicks the button, the onClick function of the assigned OnClickListener is called.

*If you import android.view.View; you use View.OnClickListener. If you import android.view.View.*; or import android.view.View.OnClickListener; you use OnClickListener as far as I get it.

Another way is to let you activity/fragment inherit from OnClickListener. This way you assign your fragment/activity as the listener for your button and implement onClick as a member-function.

I also experienced this problem and found the easy solution to be

public string ReturnValues()
{
    string _var = ""; // Setting an innitial value

    if (.....)  // Looking at conditions
    {
        _var = "true"; // Re-assign the value of _var
    }

    return _var; // Return the value of var
}

This also works with other return types and gives the least amount of problems

The initial value I chose was a fall-back value and I was able to re-assign the value as many times as required.

It uses lzop which is much faster, see:http://pokecraft.first-world.info/wiki/Quick_Benchmark:_Gzip_vs_Bzip2_vs_LZMA_vs_XZ_vs_LZ4_vs_LZO

"s" is not a "char*", it's a "char[4]". And so, "&s" is not a "char**", but actually "a pointer to an array of 4 characater". Your compiler may treat "&s" as if you had written "&s[0]", which is roughly the same thing, but is a "char*".

When you write "char** p = &s;" you are trying to say "I want p to be set to the address of the thing which currently points to "asd". But currently there is nothing which points to "asd". There is just an array which holds "asd";

char s[] = "asd";
char *p = &s[0];  // alternately you could use the shorthand char*p = s;
char **pp = &p;

I was facing the same issue then i saw while pushing my app some jar files which were loaded twice hence multiple dex error .Just go to your project properties -> Java Build Path and try unchecking jar which is being loaded twice.

I had the exact same issue, after rightly have configured in Mac OSX host a SharedFolder with Auto-Mount enabled. On the Guest OS, it is also required to install VirtualBox Guest Additions. For the case of Windows, it is:

VBoxWindowsAdditions.exe

Right after this installation, i could perfectly view the shared folder content under This PC and Network ("\VBOXSVR\Installers").

FacesContext context = FacesContext.getCurrentInstance();
HttpServletResponse response = (HttpServletResponse)context.getExternalContext().getResponse();
response.sendRedirect("somePage.jsp");

You should use the logging library, which has this capability built in. You simply add handlers to a logger to determine where to send the output.

Hello I got the best solution of this, suppose if u have to hide a particular item at on create Menu method and show that item in other fragment. I am taking an example of two menu item one is edit and other is delete. e.g menu xml is as given below:

sell_menu.xml

 <?xml version="1.0" encoding="utf-8"?>
 <menu xmlns:android="http://schemas.android.com/apk/res/android"
 xmlns:app="http://schemas.android.com/apk/res-auto">

<item
    android:id="@+id/action_edit"
    android:icon="@drawable/ic_edit_white_shadow_24dp"
    app:showAsAction="always"
    android:title="Edit" />

<item
    android:id="@+id/action_delete"
    android:icon="@drawable/ic_delete_white_shadow_24dp"
    app:showAsAction="always"
    android:title="Delete" />

Now Override the two method in your activity & make a field variable mMenu as:

  private Menu mMenu;         //  field variable    


  @Override
  public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.sell_menu, menu);
    this.mMenu = menu;

    menu.findItem(R.id.action_delete).setVisible(false);
    return super.onCreateOptionsMenu(menu);
  }

 @Override
 public boolean onOptionsItemSelected(MenuItem item) {
    if (item.getItemId() == R.id.action_delete) {
       // do action
        return true;
    } else if (item.getItemId() == R.id.action_edit) {
      // do action
        return true;
    }

    return super.onOptionsItemSelected(item);
 }

Make two following method in your Activity & call them from fragment to hide and show your menu item. These method are as:

public void showDeleteImageOption(boolean status) {
    if (menu != null) {
        menu.findItem(R.id.action_delete).setVisible(status);
    }
}

public void showEditImageOption(boolean status) {
    if (menu != null) {
        menu.findItem(R.id.action_edit).setVisible(status);
    }
}

That's Solve from my side,I think this explanation will help you.

os.system() returns the (encoded) process exit value. 0 means success:

On Unix, the return value is the exit status of the process encoded in the format specified for wait(). Note that POSIX does not specify the meaning of the return value of the C system() function, so the return value of the Python function is system-dependent.

The output you see is written to stdout, so your console or terminal, and not returned to the Python caller.

If you wanted to capture stdout, use subprocess.check_output() instead:

x = subprocess.check_output(['whoami'])

use ILIKE

SELECT * FROM trees WHERE trees.`title` ILIKE '%elm%';

it worked for me !!

According to Django documentation, inline formsets are for this purpose: "Inline formsets is a small abstraction layer on top of model formsets. These simplify the case of working with related objects via a foreign key".

See https://docs.djangoproject.com/en/dev/topics/forms/modelforms/#inline-formsets

uncaught exception: cannot call methods on button prior to initialization; attempted to call method 'disable'.

this means that you are trying to call it on an element that is not handled as a button, because no .button method was called on it. Therefore your problem MUST be the selector.

You are selecting all inputs $('input'), so it tries to call the method disable from button widget namespace not only on buttons, but on text inputs too.

$('button').attr("disabled", "disabled"); will not work with jQuery Mobile, because you modify the button that is hiden and replaced by a markup that jQuery Mobile generates.

You HAVE TO use jQueryMobile's method of disabling the button with a correct selector like:

$('div#DT1S input[type=button]').button('disable');

yes, simply use colspan.

time1 is the key of the most outer dictionary, eg, feb2012. So then you're trying to index the string, but you can only do this with integers. I think what you wanted was:

for info in courses[time1][course]:

As you're going through each dictionary, you must add another nest.

Following Aditya Singh's answer the generated (unsigned) apk would not install on my phone. I had to generate a signed apk using the instructions here.

The following worked for me:

$ keytool -genkey -v -keystore my-release-key.keystore -alias my-key-alias -keyalg RSA -keysize 2048 -validity 10000

Place the my-release-key.keystore file under the android/app directory in your project folder. Then edit the file ~/.gradle/gradle.properties and add the following (replace **** with the correct keystore password, alias and key password)

MYAPP_RELEASE_STORE_FILE=my-release-key.keystore
MYAPP_RELEASE_KEY_ALIAS=my-key-alias
MYAPP_RELEASE_STORE_PASSWORD=****
MYAPP_RELEASE_KEY_PASSWORD=****

If you're using MacOS, you can store your password in the keychain using the instructions here instead of storing it in plaintext.

Then edit app/build.gradle and ensure the following are there (the sections with signingConfigs signingConfig may need to be added) :

...
android {
    ...
    defaultConfig { ... }
    signingConfigs {
        release {
            if (project.hasProperty('MYAPP_RELEASE_STORE_FILE')) {
                storeFile file(MYAPP_RELEASE_STORE_FILE)
                storePassword MYAPP_RELEASE_STORE_PASSWORD
                keyAlias MYAPP_RELEASE_KEY_ALIAS
                keyPassword MYAPP_RELEASE_KEY_PASSWORD
            }
        }
    }
    buildTypes {
        release {
            ...
            signingConfig signingConfigs.release
        }
    }
}
...

Then run the command cd android && ./gradlew assembleRelease ,

For Windows 'cd android' and then run gradlew assembleRelease command , and find your signed apk under android/app/build/outputs/apk/app-release.apk

To build upon @pozs's answers, here are a couple more PostgreSQL functions which may be useful to some. (Requires PostgreSQL 9.3+)

Delete By Key: Deletes a value from JSON structure by key.

CREATE OR REPLACE FUNCTION "json_object_del_key"(
  "json"          json,
  "key_to_del"    TEXT
)
  RETURNS json
  LANGUAGE sql
  IMMUTABLE
  STRICT
AS $function$
SELECT CASE
  WHEN ("json" -> "key_to_del") IS NULL THEN "json"
  ELSE (SELECT concat('{', string_agg(to_json("key") || ':' || "value", ','), '}')
          FROM (SELECT *
                  FROM json_each("json")
                 WHERE "key" <> "key_to_del"
               ) AS "fields")::json
END
$function$;

Recursive Delete By Key: Deletes a value from JSON structure by key-path. (requires @pozs's json_object_set_key function)

CREATE OR REPLACE FUNCTION "json_object_del_path"(
  "json"          json,
  "key_path"      TEXT[]
)
  RETURNS json
  LANGUAGE sql
  IMMUTABLE
  STRICT
AS $function$
SELECT CASE
  WHEN ("json" -> "key_path"[l] ) IS NULL THEN "json"
  ELSE
     CASE COALESCE(array_length("key_path", 1), 0)
         WHEN 0 THEN "json"
         WHEN 1 THEN "json_object_del_key"("json", "key_path"[l])
         ELSE "json_object_set_key"(
           "json",
           "key_path"[l],
           "json_object_del_path"(
             COALESCE(NULLIF(("json" -> "key_path"[l])::text, 'null'), '{}')::json,
             "key_path"[l+1:u]
           )
         )
       END
    END
  FROM array_lower("key_path", 1) l,
       array_upper("key_path", 1) u
$function$;

Usage examples:

s1=# SELECT json_object_del_key ('{"hello":[7,3,1],"foo":{"mofu":"fuwa", "moe":"kyun"}}',
                                 'foo'),
            json_object_del_path('{"hello":[7,3,1],"foo":{"mofu":"fuwa", "moe":"kyun"}}',
                                 '{"foo","moe"}');

 json_object_del_key |          json_object_del_path
---------------------+-----------------------------------------
 {"hello":[7,3,1]}   | {"hello":[7,3,1],"foo":{"mofu":"fuwa"}}

Python 3.x version of Etaoin's answer for completeness:

from tkinter.filedialog import askopenfilename
filename = askopenfilename()

Just figured it out in Oracle Java the environmental variable is called: JAVA_TOOL_OPTIONS rather than JAVA_OPTS

You should try JRebel, which does the hot deploy stuff pretty well. A bit expensive, but worth the money. They have a trial version.

You could add the default rule with the alter table,

ALTER TABLE mytable ADD COLUMN created_at TIMESTAMP DEFAULT NOW()

then immediately set to null all the current existing rows:

UPDATE mytable SET created_at = NULL

Then from this point on the DEFAULT will take effect.
