Programs & Examples On #Mysql error 1242

We follow the guidelines listed on this page: C++ Programming Style Guidelines

I'd also recommend you read The Elements of C++ Style by Misfeldt et al, which is quite an excellent book on this topic.

For the first one: your program will go through the loop once for every row in the result set returned by the query. You can know in advance how many results there are by using mysql_num_rows().

For the second one: this time you are only using one row of the result set and you are doing something for each of the columns. That's what the foreach language construct does: it goes through the body of the loop for each entry in the array $row. The number of times the program will go through the loop is knowable in advance: it will go through once for every column in the result set (which presumably you know, but if you need to determine it you can use count($row)).

This worked for me when value came from a TextBox:

string.replace(/\n|\r\n|\r/g, '<br/>');

You can solve this problem by using AJAX. You don't need to load JQuery for AJAX but it has a better error and success handling than native JS.

I would do it like so:

1) add an click eventlistener to all my anchors on the page. 2) on click, you can setup an ajax-request to your php, in the POST-DATA you set the anchor id or the text-value 3) the php gets the value and you can setup a request to your database. Then you return the value which you need and echo it to the ajax-request. 4) your success function of the ajax-request is doing some stuff

For more information about ajax-requests look back here:

-> Ajax-Request NATIVE https://blog.garstasio.com/you-dont-need-jquery/ajax/

A simple JQuery examle:

$("button").click(function(){
  $.ajax({url: "demo_test.txt", success: function(result){
    $("#div1").html(result);
  }});
});

Works fine for me

if (/^win/i.test(process.platform)) {
    // TODO: Windows
} else {
    // TODO: Linux, Mac or something else
}

The i modifier is used to perform case-insensitive matching.

You can use the mixin make-col-ready and set the gutter width to zero:

@include make-col-ready(0);

here a solution based on @Danield solution, that works even within a div.

In that example, I am using Angular but it can quickly move to vanilla JS or another framework.

The main idea is just to move the @Danield solution within an empty iframe and copy the dimensions after iframe window size changes.

That iframe has to fit dimensions with its father element.

Here a few screenshots:

Python habitually returns None from functions and methods that mutate the data, such as list.sort, list.append, and random.shuffle, with the idea being that it hints to the fact that it was mutating.

If you want to take an iterable and return a new, sorted list of its items, use the sorted builtin function.

I know you had the issue with Occidentalis, but I had the issue on Windows too, and I didn't found anything helpful. So if you have windows, and you've installed opencv, but you still get an Import error, this method will maybe solve the issue.

I managed to solve the issue, by reactivating anaconda.

First I deleted your\path\to\anaconda3 and your\path\to\anaconda3\Scripts from PATH (you will need these later, so remember these paths)

Then if you run python from cmd it will say:

Warning:
This Python interpreter is in a conda environment, but the environment has
not been activated. Libraries may fail to load. To activate this environment
please see https://conda.io/activation.

Then in Anaconda prompt I ran these:

your\path\to\anconda3\Scripts\activate base 
conda activate --stack your\path\to\anaconda3

I'm not sure about is this the easiest way to reactivate anaconda, but this is what worked for me.

I usually use the accelerometers. A sudden change of position in a short period implies high acceleration. If this is not reflected in accelerometer telemetry it is almost certainly due to a change in the "best three" satellites used to compute position (to which I refer as GPS teleporting).

When an asset is at rest and hopping about due to GPS teleporting, if you progressively compute the centroid you are effectively intersecting a larger and larger set of shells, improving precision.

To do this when the asset is not at rest you must estimate its likely next position and orientation based on speed, heading and linear and rotational (if you have gyros) acceleration data. This is more or less what the famous K filter does. You can get the whole thing in hardware for about $150 on an AHRS containing everything but the GPS module, and with a jack to connect one. It has its own CPU and Kalman filtering on board; the results are stable and quite good. Inertial guidance is highly resistant to jitter but drifts with time. GPS is prone to jitter but does not drift with time, they were practically made to compensate each other.

This really belongs with @Ramnath's answer but I can't comment as I don't have enough reputation yet. You can also use the arrange function from the dplyr package in the same way as the plyr package.

library(dplyr)
arrange(DF, ID, desc(num))

$('b').contents().unwrap();

This selects all <b> elements, then uses .contents() to target the text content of the <b>, then .unwrap() to remove its parent <b> element.

For the greatest performance, always go native:

var b = document.getElementsByTagName('b');

while(b.length) {
    var parent = b[ 0 ].parentNode;
    while( b[ 0 ].firstChild ) {
        parent.insertBefore(  b[ 0 ].firstChild, b[ 0 ] );
    }
     parent.removeChild( b[ 0 ] );
}

This will be much faster than any jQuery solution provided here.

There's a big productivity boost if you add an Alt + F3 key binding to the Open Implementation feature, and just use F3 to go to interfaces, and Alt + F3 to go to implementations.

Just use a while loop:

var (i, sum) = (0, 0)
while (sum < 1000) {
  sum += i
  i += 1
}

I think the XML format can be so diverse that it's impossible to write a code that could do this without a very strict defined XML format. Here is what I mean:

<persons>
    <person>
        <name>Koen Bok</name>
        <age>26</age>
    </person>
    <person>
        <name>Plutor Heidepeen</name>
        <age>33</age>
    </person>
</persons>

Would become

{'persons': [
    {'name': 'Koen Bok', 'age': 26},
    {'name': 'Plutor Heidepeen', 'age': 33}]
}

But what would this be:

<persons>
    <person name="Koen Bok">
        <locations name="defaults">
            <location long=123 lat=384 />
        </locations>
    </person>
</persons>

See what I mean?

Edit: just found this article: http://www.xml.com/pub/a/2006/05/31/converting-between-xml-and-json.html

IMHO, onclick is the preferred method over .click only when the following conditions are met:

• there are many elements on the page
• only one event to be registered for the click event
• You're worried about mobile performance/battery life

I formed this opinion because of the fact that the JavaScript engines on mobile devices are 4 to 7 times slower than their desktop counterparts which were made in the same generation. I hate it when I visit a site on my mobile device and receive jittery scrolling because the jQuery is binding all of the events at the expense of my user experience and battery life. Another recent supporting factor, although this should only be a concern with government agencies ;) , we had IE7 pop-up with a message box stating that JavaScript process is taking to long...wait or cancel process. This happened every time there were a lot of elements to bind to via jQuery.

you can do it with SVN/Tortoise git as well.

just right click on node_modules -> Tortoise git -> add to ignore list.

This will generate .gitIgnore for you and you won't find node_modules folder in staging again.

Create a .htaccess file in directory and add this code to .htaccess file

AddHandler x-httpd-php .html .htm

or

AddType application/x-httpd-php .html .htm

It will force Apache server to parse HTML or HTM files as PHP Script

No, there are no dictionaries in php. The closest thing you have is an array. However, an array is different than a dictionary in that arrays have both an index and a key. Dictionaries only have keys and no index. What do I mean by that?

$array = array(
    "foo" => "bar",
    "bar" => "foo"
);

// as of PHP 5.4
$array = [
    "foo" => "bar",
    "bar" => "foo",
];

The following line is allowed with the above array but would give an error if it was a dictionary.

print $array[0]

Python has both arrays and dictionaries.

You can use it like this: http://plnkr.co/edit/vtNjEgmpItqxX5fdwtPi?p=preview

Like you found, filter accepts predicate function which accepts item by item from the array. So, you just have to create an predicate function based on the given criteria.

In this example, criteriaMatch is a function which returns a predicate function which matches the given criteria.

template:

<div ng-repeat="item in items | filter:criteriaMatch(criteria)">
  {{ item }}
</div>

scope:

$scope.criteriaMatch = function( criteria ) {
  return function( item ) {
    return item.name === criteria.name;
  };
};

Or just call mysql command with --version option.

mysql --version

In C++ operators (for POD types) always act on objects of the same type.
Thus if they are not the same one will be promoted to match the other.
The type of the result of the operation is the same as operands (after conversion).

If either is      long          double the other is promoted to      long          double
If either is                    double the other is promoted to                    double
If either is                    float  the other is promoted to                    float
If either is long long unsigned int    the other is promoted to long long unsigned int
If either is long long          int    the other is promoted to long long          int
If either is long      unsigned int    the other is promoted to long      unsigned int
If either is long               int    the other is promoted to long               int
If either is           unsigned int    the other is promoted to           unsigned int
If either is                    int    the other is promoted to                    int
Both operands are promoted to int

Note. The minimum size of operations is int. So short/char are promoted to int before the operation is done.

In all your expressions the int is promoted to a float before the operation is performed. The result of the operation is a float.

int + float =>  float + float = float
int * float =>  float * float = float
float * int =>  float * float = float
int / float =>  float / float = float
float / int =>  float / float = float
int / int                     = int
int ^ float =>  <compiler error>

For this particular relationship, you could use np.sign:

>>> df["C"] = np.sign(df.A - df.B)
>>> df
   A  B  C
a  2  2  0
b  3  1  1
c  1  3 -1

Here is a method that returns the image dimensions:

from PIL import Image
import os

def get_image_dimensions(imagefile):
    """
    Helper function that returns the image dimentions

    :param: imagefile str (path to image)
    :return dict (of the form: {width:<int>, height=<int>, size_bytes=<size_bytes>)
    """
    # Inline import for PIL because it is not a common library
    with Image.open(imagefile) as img:
        # Calculate the width and hight of an image
        width, height = img.size

    # calculat ethe size in bytes
    size_bytes = os.path.getsize(imagefile)

    return dict(width=width, height=height, size_bytes=size_bytes)

In Post API call we are sending data in request body. So if we will send data by adding any extra header to an API call. Then first OPTIONS API call will happen and then post call will happen. Therefore, you have to handle OPTION API call first.

You can handle the issue by writing a filter and inside that you have to check for option call API call and return a 200 OK status. Below is the sample code:

package com.web.filter;

import java.io.IOException;

import javax.servlet.Filter;
import javax.servlet.FilterChain;
import javax.servlet.FilterConfig;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.apache.catalina.connector.Response;

public class CustomFilter implements Filter {
    public void doFilter(ServletRequest req, ServletResponse res, FilterChain chain)
            throws IOException, ServletException {
        HttpServletResponse response = (HttpServletResponse) res;
        HttpServletRequest httpRequest = (HttpServletRequest) req;
        response.setHeader("Access-Control-Allow-Origin", "*");
        response.setHeader("Access-Control-Allow-Methods", "POST, GET, PUT, OPTIONS, DELETE");
        response.setHeader("Access-Control-Max-Age", "3600");
        response.setHeader("Access-Control-Allow-Headers", "x-requested-with, Content-Type");
        if (httpRequest.getMethod().equalsIgnoreCase("OPTIONS")) {
            response.setStatus(Response.SC_OK);
        }
        chain.doFilter(req, res);
    }

    public void init(FilterConfig filterConfig) {
        // TODO
    }

    public void destroy() {
        // Todo
    }

}

The #! line tells the kernel (specifically, the implementation of the execve system call) that this program is written in an interpreted language; the absolute pathname that follows identifies the interpreter. Programs compiled to machine code begin with a different byte sequence -- on most modern Unixes, 7f 45 4c 46 (^?ELF) that identifies them as such.

You can put an absolute path to any program you want after the #!, as long as that program is not itself a #! script. The kernel rewrites an invocation of

./script arg1 arg2 arg3 ...

where ./script starts with, say, #! /usr/bin/perl, as if the command line had actually been

/usr/bin/perl ./script arg1 arg2 arg3

Or, as you have seen, you can use #! /bin/sh to write a script intended to be interpreted by sh.

The #! line is only processed if you directly invoke the script (./script on the command line); the file must also be executable (chmod +x script). If you do sh ./script the #! line is not necessary (and will be ignored if present), and the file does not have to be executable. The point of the feature is to allow you to directly invoke interpreted-language programs without having to know what language they are written in. (Do grep '^#!' /usr/bin/* -- you will discover that a great many stock programs are in fact using this feature.)

Here are some rules for using this feature:

• The #! must be the very first two bytes in the file. In particular, the file must be in an ASCII-compatible encoding (e.g. UTF-8 will work, but UTF-16 won't) and must not start with a "byte order mark", or the kernel will not recognize it as a #! script.
• The path after #! must be an absolute path (starts with /). It cannot contain space, tab, or newline characters.
• It is good style, but not required, to put a space between the #! and the /. Do not put more than one space there.
• You cannot put shell variables on the #! line, they will not be expanded.
• You can put one command-line argument after the absolute path, separated from it by a single space. Like the absolute path, this argument cannot contain space, tab, or newline characters. Sometimes this is necessary to get things to work (#! /usr/bin/awk -f), sometimes it's just useful (#! /usr/bin/perl -Tw). Unfortunately, you cannot put two or more arguments after the absolute path.
• Some people will tell you to use #! /usr/bin/env interpreter instead of #! /absolute/path/to/interpreter. This is almost always a mistake. It makes your program's behavior depend on the $PATH variable of the user who invokes the script. And not all systems have env in the first place.
• Programs that need setuid or setgid privileges can't use #!; they have to be compiled to machine code. (If you don't know what setuid is, don't worry about this.)

Regarding csh, it relates to sh roughly as Nutrimat Advanced Tea Substitute does to tea. It has (or rather had; modern implementations of sh have caught up) a number of advantages over sh for interactive usage, but using it (or its descendant tcsh) for scripting is almost always a mistake. If you're new to shell scripting in general, I strongly recommend you ignore it and focus on sh. If you are using a csh relative as your login shell, switch to bash or zsh, so that the interactive command language will be the same as the scripting language you're learning.

Its better to access the count with the laravels count method

$count = Model::where('status','=','1')->count();

or

$count = Model::count();

Change your default controller which is in config file.

i.e : config/routes.php

$route['default_controller'] = "Your controller name";

Hope this will help.

You can use the CssClass property of the hyperlink:

LiteralControl ltr = new LiteralControl();
        ltr.Text = "<style type=\"text/css\" rel=\"stylesheet\">" +

I saw a lot of solutions but all was wrong or uncomplet. You can solve all problems with 5 lines in viewDidLoad and autolayout. This for objetive C:

_tableView.delegate = self;
_tableView.dataSource = self;
self.tableView.estimatedRowHeight = 80;//the estimatedRowHeight but if is more this autoincremented with autolayout
self.tableView.rowHeight = UITableViewAutomaticDimension;
[self.tableView setNeedsLayout];
[self.tableView layoutIfNeeded];
self.tableView.contentInset = UIEdgeInsetsMake(20, 0, 0, 0) ;

For swift 2.0:

 self.tableView.estimatedRowHeight = 80
 self.tableView.rowHeight = UITableViewAutomaticDimension      
 self.tableView.setNeedsLayout()
 self.tableView.layoutIfNeeded()
 self.tableView.contentInset = UIEdgeInsetsMake(20, 0, 0, 0)

Now create your cell with xib or into tableview in your Storyboard With this you no need implement nothing more or override. (Don forget number os lines 0) and the bottom label (constrain) downgrade "Content Hugging Priority -- Vertical to 250"

You can donwload the code in the next url: https://github.com/jposes22/exampleTableCellCustomHeight

You are looking for the command scandir.

$path    = '/tmp';
$files = scandir($path);

Following code will remove . and .. from the returned array from scandir:

$files = array_diff(scandir($path), array('.', '..'));

I need to produce both a logical model and a conceptual model. All the explanations here are really vague. The link posted above just shows the difference being that a conceptual model is a logical model without fields. Ok fine, I don't mention the name of the database. It appears to be totally redundant.

I really don't know what 'semantic' means. can someone explain what I would do differently using 'english' and possibly post a link to better examples than a picture that shows one picture that has fields and one that does not. The buzzwords are all well and good, but its so vague its not useful to practically implement.

do I do anything other than take my logical model (which is basically my physical model reversed engineered out of the DB, click a button in said tools and the images look a little different and then take off the data types).

From what i can practically see (and without buzzwords)

physical model: actually tables. The little pictures have data types in them and named pk/fk constraints Logical Model: click the little button my tool (using Oracles SQL Developer Data Modeller, I dont have an erwin license and 2010 visio no longer reverse engineers out of the DB), and then the images on the screen change slightly. The data types are gone and the names of the constraints are gone, then the colors of the table representations changes to purple (so now I call them entities).

ok. so what would my Conceptual model look like other then: exact same thing as my logical model minus the fields. I would think there is more to it than this. Reciting that its a 'semantic' representation of data sounds real nice and fancy, but doesn't make sense to someone who has not made one of these before.

For those who want to hide back button title globally.

You can swizzle viewDidLoad of UIViewController like this.

+ (void)overrideBackButtonTitle {

    NSError *error;

    // I use `Aspects` for easier swizzling.

    [UIViewController aspect_hookSelector:@selector(viewDidLoad)
                              withOptions:AspectPositionBefore
                               usingBlock:^(id<AspectInfo> aspectInfo)
    {

        UIViewController *vc = (UIViewController *)aspectInfo.instance;

        // Check whether this class is my app's view controller or not.
        // We don't want to override this for Apple's view controllers,
        // or view controllers from external framework.

        NSString *className = NSStringFromClass([vc class]);
        Class class = [NSBundle.mainBundle classNamed:className];
        if (!class) {
           return;
        }

        UIBarButtonItem *backButton = [[UIBarButtonItem alloc] initWithTitle:@" " style:UIBarButtonItemStylePlain target:nil action:nil];
        vc.navigationItem.backBarButtonItem = backButton;

    } error:&error];

    if (error) {
        NSLog(@"%s error: %@", __FUNCTION__, error.localizedDescription);
    }

}

Usage:

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    [[self class] overrideBackButtonTitle];
    return YES;
}

I would prefer the C++ min/max functions, if you are using C++, because they are type-specific. fmin/fmax will force everything to be converted to/from floating point.

Also, the C++ min/max functions will work with user-defined types as long as you have defined operator< for those types.

If you want to use the numbers method, you need an int array to store the returned value.

public static void main(String[] args){
    int[] someNumbers = numbers();
    //do whatever you want with them...
    System.out.println(Arrays.toString(someNumbers));
}

//Properly Formatted

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

Use the ajaxStop event.

For example, let's say you have a loading ... message while fetching 100 ajax requests and you want to hide that message once loaded.

From the jQuery doc:

$("#loading").ajaxStop(function() {
  $(this).hide();
});

Do note that it will wait for all ajax requests being done on that page.

If you are using Docker you need to make sure ports are exposed as well

It appears that the correct answer varies in different JS engines. Here are the results I got from the test suite linked in ninjagecko's answer:

• [].concat.apply is fastest in Chrome 83 on Windows and Android, followed by reduce (~56% slower);
• looped concat is fastest in Safari 13 on Mac, followed by reduce (~13% slower);
• reduce is fastest in Safari 12 on iOS, followed by looped concat (~40% slower);

Question 1: How can I know which conda environment is my jupyter notebook running on?

• Launch your Anaconda Prompt and run the command conda env list to list all the available conda environments.

  

  You can clearly see that I've two different conda environments installed on my PC, with my currently active environment being root(Python 2.7), indicated by the asterisk(*) symbol ahead of the path.

Question 2: How can I launch jupyter from a new conda environment?

• Now, to launch the desired conda environment, simply run activate <environment name>. In this case, activate py36

Here's a fairly simple way to achieve it by enclosing both the magnifying glass icon and the input field inside a div with relative positioning.

Absolute positioning is applied to the icon, which takes it out of the normal document layout flow. The icon is then positioned inside the input. Left padding is applied to the input so that the user's input appears to the right of the icon.

Note that this example places the magnifying glass icon on the left instead of the right. This is recommended when using <input type="search"> as Chrome adds an X button in the right side of the searchbox. If we placed the icon there it would overlay the X button and look fugly.

Here is the needed Bootstrap markup.

<div class="position-relative">
    <i class="fa fa-search position-absolute"></i>
    <input class="form-control" type="search">
</div>

...and a couple CSS classes for the things which I couldn't do with Bootstrap classes:

i {
    font-size: 1rem;
    color: #333;
    top: .75rem;
    left: .75rem
}

input {
    padding-left: 2.5rem;
}

You may have to fiddle with the values for top, left, and padding-left.

There have been a slew of recent changes in this arena, so I thought a fresh answer would be helpful.

To have a cookie sent by the browser to another site during a request the following criteria must be met:

• The Set-Cookie header from the target site must contain the SameSite=None and Secure labels. If Secure is not used the SameSite header will be ignored.
• The request must be made to a https endpoint, a requirement of the Secure flag.
• The XHRRequest must be made with withCredentials=true. If using $.ajax() this is accomplished with the xhrFields parameter (requiring jQuery=1.5.1+)
• The server must respond with Access-Control-Allow-Origin header that matches the request Origin header. (* will not be respected in this case)

A lot of people find their way to this post trying to do local development against a remote endpoint, which is possible if the above criteria are met.

I had the same question. While there are good answers here I decided to create a table-valued function. With a table (or scalar) valued function you don't have to change your stored proc. I simply did a select from the table-valued function. Note that the parameter (MyParameter is optional).

CREATE FUNCTION [dbo].[MyDateFunction] 
(@MyParameter varchar(max))
RETURNS TABLE 
AS
RETURN 
(
    --- Query your table or view or whatever and select the results.
    SELECT DateValue FROM MyTable WHERE ID = @MyParameter;
)

To assign to your variable you simply can do something like:

Declare @MyDate datetime;
SET @MyDate = (SELECT DateValue FROM MyDateFunction(@MyParameter));

You can also use a scalar valued function:

CREATE FUNCTION TestDateFunction()  
RETURNS datetime  
BEGIN  
    RETURN (SELECT GetDate());
END

Then you can simply do

Declare @MyDate datetime;
SET @MyDate = (Select dbo.TestDateFunction());
SELECT @MyDate;

In General:

An example of an easy way to post XML data and get the response (as a string) would be the following function:

public string postXMLData(string destinationUrl, string requestXml)
{
    HttpWebRequest request = (HttpWebRequest)WebRequest.Create(destinationUrl);
    byte[] bytes;
    bytes = System.Text.Encoding.ASCII.GetBytes(requestXml);
    request.ContentType = "text/xml; encoding='utf-8'";
    request.ContentLength = bytes.Length;
    request.Method = "POST";
    Stream requestStream = request.GetRequestStream();
    requestStream.Write(bytes, 0, bytes.Length);
    requestStream.Close();
    HttpWebResponse response;
    response = (HttpWebResponse)request.GetResponse();
    if (response.StatusCode == HttpStatusCode.OK)
    {
        Stream responseStream = response.GetResponseStream();
        string responseStr = new StreamReader(responseStream).ReadToEnd();
        return responseStr;
    }
    return null;
}

In your specific situation:

Instead of:

request.ContentType = "application/x-www-form-urlencoded";

use:

request.ContentType = "text/xml; encoding='utf-8'";

Also, remove:

string postData = "XMLData=" + Sendingxml;

And replace:

byte[] byteArray = Encoding.UTF8.GetBytes(postData);

with:

byte[] byteArray = Encoding.UTF8.GetBytes(Sendingxml.ToString());

set termout off doesn't work from the command line, so create a file e.g. termout_off.sql containing the line:

set termout off

and call this from the SQL prompt:

SQL> @termout_off

To create the datepicker and set the date.

$('.next_date').datepicker({ dateFormat: 'dd-mm-yy'}).datepicker("setDate", new Date());

You need to update the date format:

select * from hockey_stats 
where game_date between '2012-03-11 00:00:00' and '2012-05-11 23:59:00' 
order by game_date desc;

Did the following for a spring application running static, rest and websocket content.

The Apache is used as Proxy and SSL Endpoint for the following URIs:

• /app → static content
• /api → REST API
• /api/ws → websocket

Apache configuration

<VirtualHost *:80>
    ServerName xxx.xxx.xxx    

    ProxyRequests Off
    ProxyVia Off
    ProxyPreserveHost On

    <Proxy *>
         Require all granted
    </Proxy>

    RewriteEngine On

    # websocket 
    RewriteCond %{HTTP:Upgrade}         =websocket                      [NC]
    RewriteRule ^/api/ws/(.*)           ws://localhost:8080/api/ws/$1   [P,L]

    # rest
    ProxyPass /api http://localhost:8080/api
    ProxyPassReverse /api http://localhost:8080/api

    # static content    
    ProxyPass /app http://localhost:8080/app
    ProxyPassReverse /app http://localhost:8080/app 
</VirtualHost>

I use the same vHost config for the SSL configuration, no need to change anything proxy related.

Spring configuration

server.use-forward-headers: true

Try doing this in a shell:

var="  3918912k"
echo ${var//[[:blank:]]/}

That uses parameter expansion (it's a non posix feature)

[[:blank:]] is a POSIX regex class (remove spaces, tabs...), see http://www.regular-expressions.info/posixbrackets.html

You can use Class#getDeclaredFields() to get all declared fields of the class. You can use Field#get() to get the value.

In short:

Object someObject = getItSomehow();
for (Field field : someObject.getClass().getDeclaredFields()) {
    field.setAccessible(true); // You might want to set modifier to public first.
    Object value = field.get(someObject); 
    if (value != null) {
        System.out.println(field.getName() + "=" + value);
    }
}

To learn more about reflection, check the Sun tutorial on the subject.

That said, the fields does not necessarily all represent properties of a VO. You would rather like to determine the public methods starting with get or is and then invoke it to grab the real property values.

for (Method method : someObject.getClass().getDeclaredMethods()) {
    if (Modifier.isPublic(method.getModifiers())
        && method.getParameterTypes().length == 0
        && method.getReturnType() != void.class
        && (method.getName().startsWith("get") || method.getName().startsWith("is"))
    ) {
        Object value = method.invoke(someObject);
        if (value != null) {
            System.out.println(method.getName() + "=" + value);
        }
    }
}

That in turn said, there may be more elegant ways to solve your actual problem. If you elaborate a bit more about the functional requirement for which you think that this is the right solution, then we may be able to suggest the right solution. There are many, many tools available to massage javabeans.

Duck typing:

If it talks and walks like a duck, then it is a duck

This is typically called abduction (abductive reasoning or also called retroduction, a clearer definition I think):

• from C (conclusion, what we see) and R (rule, what we know), we accept/decide/assume P (Premise, property) in other words a given fact

  ... the very basis of medical diagnosis

  with ducks: C = walks, talks, R = like a duck, P = it's a duck

Back to programming:

• object o has method/property mp1 and interface/type T requires/defines mp1

• object o has method/property mp2 and interface/type T requires/defines mp2

• ...

So, more than simply accepting mp1... on any object as long has it meets some definition of mp1..., compiler/runtime should also be okay with the assertion o is of type T

And well, is it the case with examples above? Is Duck typing is essentially no typing at all? Or should we call it implicit typing?

Python does have a multiline string/comment syntax in the sense that unless used as docstrings, multiline strings generate no bytecode -- just like #-prepended comments. In effect, it acts exactly like a comment.

On the other hand, if you say this behavior must be documented in the official documentation to be a true comment syntax, then yes, you would be right to say it is not guaranteed as part of the language specification.

In any case, your text editor should also be able to easily comment-out a selected region (by placing a # in front of each line individually). If not, switch to a text editor that does.

Programming in Python without certain text editing features can be a painful experience. Finding the right editor (and knowing how to use it) can make a big difference in how the Python programming experience is perceived.

Not only should the text editor be able to comment-out selected regions, it should also be able to shift blocks of code to the left and right easily, and it should automatically place the cursor at the current indentation level when you press Enter. Code folding can also be useful.

To protect against link decay, here is the content of Guido van Rossum's tweet:

@BSUCSClub Python tip: You can use multi-line strings as multi-line comments. Unless used as docstrings, they generate no code! :-)

Since Node 7.6, you can combine the functions promisify function from the utils module with setTimeout() .

Node.js

const sleep = require('util').promisify(setTimeout)

Javascript

const sleep = m => new Promise(r => setTimeout(r, m))

Usage

(async () => {
    console.time("Slept for")
    await sleep(3000)
    console.timeEnd("Slept for")
})()

You cannot have spaces around the = sign.

When you write:

STR = "foo"

bash tries to run a command named STR with 2 arguments (the strings = and foo)

When you write:

STR =foo

bash tries to run a command named STR with 1 argument (the string =foo)

When you write:

STR= foo

bash tries to run the command foo with STR set to the empty string in its environment.

I'm not sure if this helps to clarify or if it is mere obfuscation, but note that:

1. the first command is exactly equivalent to: STR "=" "foo",
2. the second is the same as STR "=foo",
3. and the last is equivalent to STR="" foo.

The relevant section of the sh language spec, section 2.9.1 states:

A "simple command" is a sequence of optional variable assignments and redirections, in any sequence, optionally followed by words and redirections, terminated by a control operator.

In that context, a word is the command that bash is going to run. Any string containing = (in any position other than at the beginning of the string) which is not a redirection and in which the portion of the string before the = is a valid variable name is a variable assignment, while any string that is not a redirection or a variable assignment is a command. In STR = "foo", STR is not a variable assignment.

You can run OpenSSH on Cygwin, and even install it as a Windows service.

I once used it this way to easily add backups of a Unix system - it would rsync a bunch of files onto the Windows server, and the Windows server had full tape backups.

In the last statement you are converting the duration to time which also considers the timezone. I assume that your timezone is +530, so 5 hours and 30 minutes gets added to 30 minutes. You can do as given below.

var eventTime= 1366549200; // Timestamp - Sun, 21 Apr 2013 13:00:00 GMT
var currentTime = 1366547400; // Timestamp - Sun, 21 Apr 2013 12:30:00 GMT
var diffTime = eventTime - currentTime;
var duration = moment.duration(diffTime*1000, 'milliseconds');
var interval = 1000;

setInterval(function(){
  duration = moment.duration(duration - interval, 'milliseconds');
    $('.countdown').text(duration.hours() + ":" + duration.minutes() + ":" + duration.seconds())
}, interval);

It will also work with display:table - a useful display property in this case because it doesn't require a width to be set. (I know this post is 5 years old, but it's still relevant to passers-by ;)

Here is my solution:

dependencies: Gmaps.js, jQuery

var Maps = function($) {
   var lost_addresses = [],
       geocode_count  = 0;

   var addMarker = function() { console.log('Marker Added!') };

   return {
     getGecodeFor: function(addresses) {
        var latlng;
        lost_addresses = [];
        for(i=0;i<addresses.length;i++) {
          GMaps.geocode({
            address: addresses[i],
            callback: function(response, status) {
              if(status == google.maps.GeocoderStatus.OK) {
                addMarker();
              } else if(status == google.maps.GeocoderStatus.OVER_QUERY_LIMIT) {
                lost_addresses.push(addresses[i]);
              }

               geocode_count++;
               // notify listeners when the geocode is done
               if(geocode_count == addresses.length) {
                 $.event.trigger({ type: 'done:geocoder' });
               }
            }
          });
        }
     },
     processLostAddresses: function() {
       if(lost_addresses.length > 0) {
         this.getGeocodeFor(lost_addresses);
       }
     }
   };
}(jQuery);

Maps.getGeocodeFor(address);

// listen to done:geocode event and process the lost addresses after 1.5s
$(document).on('done:geocode', function() {
  setTimeout(function() {
    Maps.processLostAddresses();
  }, 1500);
});

MySQL INSERT Syntax does not support the WHERE clause so your query as it stands will fail. Assuming your id column is unique or primary key:

If you're trying to insert a new row with ID 1 you should be using:

INSERT INTO Users(id, weight, desiredWeight) VALUES(1, 160, 145);

If you're trying to change the weight/desiredWeight values for an existing row with ID 1 you should be using:

UPDATE Users SET weight = 160, desiredWeight = 145 WHERE id = 1;

If you want you can also use INSERT .. ON DUPLICATE KEY syntax like so:

INSERT INTO Users (id, weight, desiredWeight) VALUES(1, 160, 145) ON DUPLICATE KEY UPDATE weight=160, desiredWeight=145

OR even like so:

INSERT INTO Users SET id=1, weight=160, desiredWeight=145 ON DUPLICATE KEY UPDATE weight=160, desiredWeight=145

It's also important to note that if your id column is an autoincrement column then you might as well omit it from your INSERT all together and let mysql increment it as normal.

You don't have to do this locally either. You can do it through a remote repository, for example:

svn export http://<repo>/process/test.txt /path/to/code/

Use this code

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

    <corners
        android:bottomLeftRadius="5dp"
        android:bottomRightRadius="5dp"
        android:radius="0.1dp"
        android:topLeftRadius="5dp"
        android:topRightRadius="5dp" />

    <solid android:color="#Efffff" />

    <stroke
        android:width="2dp"
        android:color="#25aaff" />

</shape>

And the correct answer is (Visual Studio 2010):

From the menus:

Tools -> Options --> Environment -> Fonts and Colors:

Select "Plain Text".

On the right of that, under "Item backgroud:" hit the dropdown list.

As you will see, the "default" list of colours in here are way too strong for a background, so you'll have to hit "Custom...".

I highly recommend a very, very pale creamy yellow colour. When you've dragged the crosshair over the exact colour you wish, hit the hue arrow sidebar indicator on the right of the colour palette in order to view your selected colour in the "Color" indicator.

If you wish to save this colour for future reference, click on a vacant white space under "Custom Colours:", and hit the "Add to Custom Colors" button. Your newly selected colour will be saved here. Click OK twice.

Tip: In order to overwrite any of these custom colours with a new one, make sure you click the required square so the dotted surround appears, before adding the new colour to the palette position.

My work is done here.

:)

The problem is that you can't use a list as the key in a dict, since dict keys need to be immutable. Use a tuple instead.

This is a list:

[x, y]

This is a tuple:

(x, y)

Note that in most cases, the ( and ) are optional, since , is what actually defines a tuple (as long as it's not surrounded by [] or {}, or used as a function argument).

You might find the section on tuples in the Python tutorial useful:

Though tuples may seem similar to lists, they are often used in different situations and for different purposes. Tuples are immutable, and usually contain an heterogeneous sequence of elements that are accessed via unpacking (see later in this section) or indexing (or even by attribute in the case of namedtuples). Lists are mutable, and their elements are usually homogeneous and are accessed by iterating over the list.

And in the section on dictionaries:

Unlike sequences, which are indexed by a range of numbers, dictionaries are indexed by keys, which can be any immutable type; strings and numbers can always be keys. Tuples can be used as keys if they contain only strings, numbers, or tuples; if a tuple contains any mutable object either directly or indirectly, it cannot be used as a key. You can’t use lists as keys, since lists can be modified in place using index assignments, slice assignments, or methods like append() and extend().

In case you're wondering what the error message means, it's complaining because there's no built-in hash function for lists (by design), and dictionaries are implemented as hash tables.

Using the documented jquery .data(obj) syntax allows you to store an object on the DOM element. Inspecting the element will not show the data- attribute because there is no key specified for the value of the object. However, data within the object can be referenced by key with .data("foo") or the entire object can be returned with .data().

So assuming you set up a loop and result[i] = { name: "image_name" } :

$('.delete')[i].data(results[i]); // => <button class="delete">Delete</delete>
$('.delete')[i].data('name'); // => "image_name"
$('.delete')[i].data(); // => { name: "image_name" }

If I want tranfer only the response variable y instead of a linear model with x specified, eg I wanna transfer/normalize a list of data, I can take 1 for x, then the object becomes a linear model:

library(MASS)
y = rf(500,30,30)
hist(y,breaks = 12)
result = boxcox(y~1, lambda = seq(-5,5,0.5))
mylambda = result$x[which.max(result$y)]
mylambda
y2 = (y^mylambda-1)/mylambda
hist(y2)

If you have some changes on your workspace and you want to stash them into a new branch use this command:

git stash branch branchName

It will make:

1. a new branch
2. move changes to this branch
3. and remove latest stash (Like: git stash pop)

Basic Structure Here is an example of a JUnit output file, showing a skip and failed result, as well as a single passed result.

<?xml version="1.0" encoding="UTF-8"?>
<testsuites>
   <testsuite name="JUnitXmlReporter" errors="0" tests="0" failures="0" time="0" timestamp="2013-05-24T10:23:58" />
   <testsuite name="JUnitXmlReporter.constructor" errors="0" skipped="1" tests="3" failures="1" time="0.006" timestamp="2013-05-24T10:23:58">
      <properties>
         <property name="java.vendor" value="Sun Microsystems Inc." />
         <property name="compiler.debug" value="on" />
         <property name="project.jdk.classpath" value="jdk.classpath.1.6" />
      </properties>
      <testcase classname="JUnitXmlReporter.constructor" name="should default path to an empty string" time="0.006">
         <failure message="test failure">Assertion failed</failure>
      </testcase>
      <testcase classname="JUnitXmlReporter.constructor" name="should default consolidate to true" time="0">
         <skipped />
      </testcase>
      <testcase classname="JUnitXmlReporter.constructor" name="should default useDotNotation to true" time="0" />
   </testsuite>
</testsuites>

Below is the documented structure of a typical JUnit XML report. Notice that a report can contain 1 or more test suite. Each test suite has a set of properties (recording environment information). Each test suite also contains 1 or more test case and each test case will either contain a skipped, failure or error node if the test did not pass. If the test case has passed, then it will not contain any nodes. For more details of which attributes are valid for each node please consult the following section "Schema".

<testsuites>        => the aggregated result of all junit testfiles
  <testsuite>       => the output from a single TestSuite
    <properties>    => the defined properties at test execution
      <property>    => name/value pair for a single property
      ...
    </properties>
    <error></error> => optional information, in place of a test case - normally if the tests in the suite could not be found etc.
    <testcase>      => the results from executing a test method
      <system-out>  => data written to System.out during the test run
      <system-err>  => data written to System.err during the test run
      <skipped/>    => test was skipped
      <failure>     => test failed
      <error>       => test encountered an error
    </testcase>
    ...
  </testsuite>
  ...
</testsuites>

This is the simplest way I use to make request: using 'request' module.

Command to install 'request' module :

$ npm install request

Example code:

var request = require('request')

var options = {
  method: 'post',
  body: postData, // Javascript object
  json: true, // Use,If you are sending JSON data
  url: url,
  headers: {
    // Specify headers, If any
  }
}

request(options, function (err, res, body) {
  if (err) {
    console.log('Error :', err)
    return
  }
  console.log(' Body :', body)

});

You can also use Node.js's built-in 'http' module to make request.

This solution worked for me:

just add another class into your table element: w-100 d-block d-md-table

so it would be : <table class="table table-responsive w-100 d-block d-md-table">

for bootstrap 4 w-100 set the width to 100% d-block (display: block) and d-md-table (display: table on min-width: 576px)

Bootstrap 4 display docs

I think it is the autoboxing that is throwing you off.

This part of your code:

   public static Integer inc(Integer i) {
        i = i+1;    // I think that this must be **sneakally** creating a new integer...  
        System.out.println("Inc: "+i);
        return i;
    }

Really boils down to code that looks like:

  public static Integer inc(Integer i) {
        i = new Integer(i) + new Integer(1);      
        System.out.println("Inc: "+i);
        return i;
    }

Which of course.. will not changes the reference passed in.

You could fix it with something like this

  public static void main(String[] args) {
        Integer integer = new Integer(0);
        for (int i =0; i<10; i++){
            integer = inc(integer);
            System.out.println("main: "+integer);
        }
    }

The solution above won't work if the original string has no spaces.

Try this:

var title = "This is your title";
var shortText = jQuery.trim(title).substring(0, 10)
                          .trim(this) + "...";

Extending @Ryogi answer above, you can take advantage of the lower.tail parameter like so:

qt(0.25/2, 40, lower.tail = FALSE) # 75% confidence

qt(0.01/2, 40, lower.tail = FALSE) # 99% confidence

You have to be sure to use UIPickerViewDataSource and UIPickerViewDelegate protocols or it will throw an AppDelegate error as of swift 3

Also please take note of the change in syntax:

func numberOfComponentsInPickerView(pickerView: UIPickerView) -> Int

is now:

public func numberOfComponents(in pickerView: UIPickerView) -> Int

The following below worked for me.

import UIkit

class ViewController: UIViewController, UIPickerViewDataSource, UIPickerViewDelegate {

    @IBOutlet weak var textBox: UITextField!
    @IBOutlet weak var dropDown: UIPickerView!

    var list = ["1", "2", "3"]

    public func numberOfComponents(in pickerView: UIPickerView) -> Int{
        return 1
    }

    public func pickerView(_ pickerView: UIPickerView, numberOfRowsInComponent component: Int) -> Int{

        return list.count
    }

    func pickerView(_ pickerView: UIPickerView, titleForRow row: Int, forComponent component: Int) -> String? {

        self.view.endEditing(true)
        return list[row]
    }

    func pickerView(_ pickerView: UIPickerView, didSelectRow row: Int, inComponent component: Int) {

        self.textBox.text = self.list[row]
        self.dropDown.isHidden = true
    }

    func textFieldDidBeginEditing(_ textField: UITextField) {

        if textField == self.textBox {
            self.dropDown.isHidden = false
            //if you don't want the users to se the keyboard type:

            textField.endEditing(true)
        }
    }
}

For anyone else who doesn't need to do it programmatic, here's a quick way:

(probably for paid users only)

1. Open the channel in web or the desktop app, and click the cog (top right).
2. Choose "Additional options..." to bring up the archival menu. notes
3. Select "Set the channel message retention policy".
4. Set "Retain all messages for a specific number of days".
5. All messages older than this time are deleted permanently!

I usually set this option to "1 day" to leave the channel with some context, then I go back into the above settings, and set it's retention policy back to "default" to go continue storing them from now-on.

Notes:
Luke points out: If the option is hidden: you have to go to global workspace Admin settings, Message Retention & Deletion, and check "Let workspace members override these settings"

// array of $ids that you need to select
$ids = array('1', '2', '3', '4', '5', '6', '7', '8');

// create sql part for IN condition by imploding comma after each id
$in = '(' . implode(',', $ids) .')';

// create sql
$sql = 'SELECT * FROM products WHERE catid IN ' . $in;

// see what you get
var_dump($sql);

Update: (a short version and update missing comma)

$ids = array('1','2','3','4');
$sql = 'SELECT * FROM products WHERE catid IN (' . implode(',', $ids) . ')';

It should be pretty obvious from your question that you're actually just asking about the difference between git merge and git rebase.

So let's suppose you're in the common case - you've done some work on your master branch, and you pull from origin's, which also has done some work. After the fetch, things look like this:

- o - o - o - H - A - B - C (master)
               \
                P - Q - R (origin/master)

If you merge at this point (the default behavior of git pull), assuming there aren't any conflicts, you end up with this:

- o - o - o - H - A - B - C - X (master)
               \             /
                P - Q - R --- (origin/master)

If on the other hand you did the appropriate rebase, you'd end up with this:

- o - o - o - H - P - Q - R - A' - B' - C' (master)
                          |
                          (origin/master)

The content of your work tree should end up the same in both cases; you've just created a different history leading up to it. The rebase rewrites your history, making it look as if you had committed on top of origin's new master branch (R), instead of where you originally committed (H). You should never use the rebase approach if someone else has already pulled from your master branch.

Finally, note that you can actually set up git pull for a given branch to use rebase instead of merge by setting the config parameter branch.<name>.rebase to true. You can also do this for a single pull using git pull --rebase.

Here is my version. Can be extended to accommodate more number of parameters and can extend formatting based on type. Currently only date and datetime types are formatted.

Example:

select dbo.FormatString('some string %s some int %s date %s','"abcd"',100,cast(getdate() as date),DEFAULT,DEFAULT)
select dbo.FormatString('some string %s some int %s date time %s','"abcd"',100,getdate(),DEFAULT,DEFAULT)

Output:

some string "abcd" some int 100 date 29-Apr-2017
some string "abcd" some int 100 date time 29-Apr-2017 19:40

Functions:

       select @result = REPLACE(CONVERT(CHAR(11), @param, 106), ' ', '-')
    end
    else  if (SQL_VARIANT_PROPERTY(@param,'BaseType') in ('datetime','datetime2'))

Initially: confusion

When originally writing this answer, I had recently made the switch from Visual Studio (with years of experience) to Linux and the first thing I did was try to find a reasonable IDE. At the time this was impossible: no good IDE existed.

Epiphany: UNIX is an IDE. All of it.¹

And then I realised that the IDE in Linux is the command line with its tools:

• First you set up your shell
  • Bash, in my case, but many people prefer
  • fish or
  • (Oh My) Zsh;
• and your editor; pick your poison — both are state of the art:
  • Neovim² or
  • Emacs.

Depending on your needs, you will then have to install and configure several plugins to make the editor work nicely (that’s the one annoying part). For example, most programmers on Vim will benefit from the YouCompleteMe plugin for smart autocompletion.

Once that’s done, the shell is your command interface to interact with the various tools — Debuggers (gdb), Profilers (gprof, valgrind), etc. You set up your project/build environment using Make, CMake, SnakeMake or any of the various alternatives. And you manage your code with a version control system (most people use Git). You also use tmux (previously also screen) to multiplex (= think multiple windows/tabs/panels) and persist your terminal session.

The point is that, thanks to the shell and a few tool writing conventions, these all integrate with each other. And that way the Linux shell is a truly integrated development environment, completely on par with other modern IDEs. (This doesn’t mean that individual IDEs don’t have features that the command line may be lacking, but the inverse is also true.)

To each their own

I cannot overstate how well the above workflow functions once you’ve gotten into the habit. But some people simply prefer graphical editors, and in the years since this answer was originally written, Linux has gained a suite of excellent graphical IDEs for several different programming languages (but not, as far as I’m aware, for C++). Do give them a try even if — like me — you end up not using them. Here’s just a small and biased selection:

• For Python development, there’s PyCharm
• For R, there’s RStudio
• For JavaScript and TypeScript, there’s Visual Studio Code (which is also a good all-round editor)
• And finally, many people love the Sublime Text editor for general code editing.

Keep in mind that this list is far from complete.

¹ I stole that title from dsm’s comment.

² I used to refer to Vim here. And while plain Vim is still more than capable, Neovim is a promising restart, and it’s modernised a few old warts.

Just in case you have a nullable property in your class object:

private static DataTable ConvertToDatatable<T>(List<T> data)
{
    PropertyDescriptorCollection props = TypeDescriptor.GetProperties(typeof(T));
    DataTable table = new DataTable();
    for (int i = 0; i < props.Count; i++)
    {
        PropertyDescriptor prop = props[i];
        if (prop.PropertyType.IsGenericType && prop.PropertyType.GetGenericTypeDefinition() == typeof(Nullable<>))
            table.Columns.Add(prop.Name, prop.PropertyType.GetGenericArguments()[0]); 
        else
            table.Columns.Add(prop.Name, prop.PropertyType);
    }

    object[] values = new object[props.Count];
    foreach (T item in data)
    {
        for (int i = 0; i < values.Length; i++)
        {
            values[i] = props[i].GetValue(item);
        }
        table.Rows.Add(values);
    }
    return table;
 }

The easiest approach to get things working with both java 8 and java 7 is to use a profile in the build:

<profiles>
  <profile>
    <id>doclint-java8-disable</id>
    <activation>
      <jdk>[1.8,)</jdk>
    </activation>

    <build>
      <plugins>
        <plugin>
          <groupId>org.apache.maven.plugins</groupId>
          <artifactId>maven-javadoc-plugin</artifactId>
          <configuration>
            <additionalparam>-Xdoclint:none</additionalparam>
          </configuration>
        </plugin>
      </plugins>
    </build>
  </profile>
</profiles>

Use regular expression to match your requirement.

String num,num1,num2;
String str = "123-456-789";
String regex ="(\\d+)";
Matcher matcher = Pattern.compile( regex ).matcher( str);
while (matcher.find( ))
{
num = matcher.group();     
System.out.print(num);                 
}

I recently struggled with this issue for 3 days. How the client is sending the request might not be the cause, the server might not be configured to handle multipart requests. This is what I had to do to get it working:

pom.xml - Added commons-fileupload dependency (download and add the jar to your project if you are not using dependency management such as maven)

<dependency>
  <groupId>commons-fileupload</groupId>
  <artifactId>commons-fileupload</artifactId>
  <version>${commons-version}</version>
</dependency>

web.xml - Add multipart filter and mapping

<filter>
  <filter-name>multipartFilter</filter-name>
  <filter-class>org.springframework.web.multipart.support.MultipartFilter</filter-class>
</filter>
<filter-mapping>
  <filter-name>multipartFilter</filter-name>
  <url-pattern>/springrest/*</url-pattern>
</filter-mapping>

app-context.xml - Add multipart resolver

<beans:bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
    <beans:property name="maxUploadSize">
        <beans:value>10000000</beans:value>
    </beans:property>
</beans:bean>

Your Controller

@RequestMapping(value=Constants.REQUEST_MAPPING_ADD_IMAGE, method = RequestMethod.POST, produces = { "application/json"})
public @ResponseBody boolean saveStationImage(
        @RequestParam(value = Constants.MONGO_STATION_PROFILE_IMAGE_FILE) MultipartFile file,
        @RequestParam(value = Constants.MONGO_STATION_PROFILE_IMAGE_URI) String imageUri, 
        @RequestParam(value = Constants.MONGO_STATION_PROFILE_IMAGE_TYPE) String imageType, 
        @RequestParam(value = Constants.MONGO_FIELD_STATION_ID) String stationId) {
    // Do something with file
    // Return results
}

Your client

public static Boolean updateStationImage(StationImage stationImage) {
    if(stationImage == null) {
        Log.w(TAG + ":updateStationImage", "Station Image object is null, returning.");
        return null;
    }

    Log.d(TAG, "Uploading: " + stationImage.getImageUri());
    try {
        RestTemplate restTemplate = new RestTemplate();
        FormHttpMessageConverter formConverter = new FormHttpMessageConverter();
        formConverter.setCharset(Charset.forName("UTF8"));
        restTemplate.getMessageConverters().add(formConverter);
        restTemplate.getMessageConverters().add(new MappingJackson2HttpMessageConverter());

        restTemplate.setRequestFactory(new HttpComponentsClientHttpRequestFactory());

        HttpHeaders httpHeaders = new HttpHeaders();
        httpHeaders.setAccept(Collections.singletonList(MediaType.parseMediaType("application/json")));

        MultiValueMap<String, Object> parts = new LinkedMultiValueMap<String, Object>();

        parts.add(Constants.STATION_PROFILE_IMAGE_FILE, new FileSystemResource(stationImage.getImageFile()));
        parts.add(Constants.STATION_PROFILE_IMAGE_URI, stationImage.getImageUri());
        parts.add(Constants.STATION_PROFILE_IMAGE_TYPE, stationImage.getImageType());
        parts.add(Constants.FIELD_STATION_ID, stationImage.getStationId());

        return restTemplate.postForObject(Constants.REST_CLIENT_URL_ADD_IMAGE, parts, Boolean.class);
    } catch (Exception e) {
        StringWriter sw = new StringWriter();
        e.printStackTrace(new PrintWriter(sw));

        Log.e(TAG + ":addStationImage", sw.toString());
    }

    return false;
}

That should do the trick. I added as much information as possible because I spent days, piecing together bits and pieces of the full issue, I hope this will help.

It is the simplest one I could come up with, so wanted to share here,

#include<iostream.h>
#include<conio.h>
void main()
{
//clear the screen.
clrscr();
//declare variable type float
float cel, fah;
//Input the Temperature in given unit save them in ‘cel’
cout<<”Enter the Temperature in Celsius”<<endl;
cin>>cel;
//convert and save it in ‘fah’
fah=1.8*cel+32.0;
//show the output ‘fah’
cout<<”Temperature in Fahrenheit is “<<fah;
//get character
getch();
}

Source: Celsius to Fahrenheit

I had the same issues on my notebook which runs Windows 8.1

Try this:

• Check if Hyper-V options in "Windows Features activate or deactivate" are deactivated
• Download and install the latest Oracle VirtualBox
• Reboot
• Install HAXM
• Reboot-->open BIOS--> Enable 'Execute Disable'

It looks like that the installation of VirtualBox sets a flag that "turns" VT-X on.

you can try this:

Uninstall office365

then install only Access Database Engine 2016 Redistributable 64 bit

Also set Project Configuration Properties for Debugging Run64BitRuntime = False

It should work.

November 2020 Update

I searched for the top NodeJS html parser libraries.

Because my use cases didn't require a library with many features, I could focus on stability and performance.

By stability I mean that I want the library to be used long enough by the community in order to find bugs and that it will be still maintained and that open issues will be closed.

Its hard to understand the future of an open source library, but I did a small summary based on the top 10 libraries in openbase.

I divided into 2 groups according to the last commit (and on each group the order is according to Github starts):

Last commit is in the last 6 months:

jsdom - Last commit: 3 Months, Open issues: 331, Github stars: 14.9K.

htmlparser2 - Last commit: 8 days, Open issues: 2, Github stars: 2.7K.

parse5 - Last commit: 2 Months, Open issues: 21, Github stars: 2.5K.

swagger-parser - Last commit: 2 Months, Open issues: 48, Github stars: 663.

html-parse-stringify - Last commit: 4 Months, Open issues: 3, Github stars: 215.

node-html-parser - Last commit: 7 days, Open issues: 15, Github stars: 205.

Last commit is 6 months and above:

cheerio - Last commit: 1 year, Open issues: 174, Github stars: 22.9K.

koa-bodyparser - Last commit: 6 months, Open issues: 9, Github stars: 1.1K.

sax-js - Last commit: 3 Years, Open issues: 65, Github stars: 941.

draftjs-to-html - Last commit: 1 Year, Open issues: 27, Github stars: 233.

I picked Node-html-parser because it seems quiet fast and very active at this moment.

(*) Openbase adds much more information regarding each library like the number of contributors (with +3 commits), weekly downloads, Monthly commits, Version etc'.

(**) The table above is a snapshot according to the specific time and date - I would check the reference again and as a first step check the level of recent activity and then dive into the smaller details.

its a way to do things over and over indefinitely such that every option is used.

for example if you wanted to get all the links on an html page you will want to have recursions because when you get all the links on page 1 you will want to get all the links on each of the links found on the first page. then for each link to a newpage you will want those links and so on... in other words it is a function that calls itself from inside itself.

when you do this you need a way to know when to stop or else you will be in an endless loop so you add an integer param to the function to track the number of cycles.

in c# you will have something like this:

private void findlinks(string URL, int reccursiveCycleNumb)    {
   if (reccursiveCycleNumb == 0)
        {
            return;
        }

        //recursive action here
        foreach (LinkItem i in LinkFinder.Find(URL))
        {
            //see what links are being caught...
            lblResults.Text += i.Href + "<BR>";

            findlinks(i.Href, reccursiveCycleNumb - 1);
        }

        reccursiveCycleNumb -= reccursiveCycleNumb;
}

If using NuGet all I had to do was:

1. right click project and click Manage NuGet Packages..

2. click the cog in top right

3. click General tab in NuGet Package Manager above Package Sources

4. check "Skip Applying binding redirects" in Binding Redirects

5. Clean and rebuild and the warning's gone

Easy peasy

If it IS a foreach loop as you have described in the question, using $key => $value is fast and efficient.

thisReader.GetString(int columnIndex)

Strings are immutable, so you need to say

sInputString = sInputString("\"","");

not just the right side of the =

You could create an extension method to add all property values through reflection:

public static DataSet ToDataSet<T>(this IList<T> list)
{
    Type elementType = typeof(T);
    DataSet ds = new DataSet();
    DataTable t = new DataTable();
    ds.Tables.Add(t);

    //add a column to table for each public property on T
    foreach(var propInfo in elementType.GetProperties())
    {
        t.Columns.Add(propInfo.Name, propInfo.PropertyType);
    }

    //go through each property on T and add each value to the table
    foreach(T item in list)
    {
        DataRow row = t.NewRow();
        foreach(var propInfo in elementType.GetProperties())
        {
            row[propInfo.Name] = propInfo.GetValue(item, null);
        }
    }

    return ds;
}

this.$('#datepicker').datepicker({minDate: 1});

minDate:0 - Enable dates in the calender from the current date. MinDate:1 enable dates in the calender currentDate+1

To Restrict date between from tomorrow and the same day next month u need to give something like

$( "#datepicker" ).datepicker({ minDate: 1, maxDate: "+1M" });

I am sure there is a smarter way for doing what you want but this should work:

- name         : Test var
  hosts        : all
  gather_facts : no
  vars:
    myvariable : false
  tasks:
    - name: param1
      set_fact:
        myvariable: "{{param1}}"
      when: param1 is defined

    - name: param2
      set_fact:
        myvariable: "{{ param2 if not myvariable else myvariable + ',' + param2 }}"
      when: param2 is defined

    - name: param3
      set_fact:
        myvariable: "{{ param3 if not myvariable else myvariable + ',' + param3 }}"
      when: param3 is defined

    - name: default
      set_fact:
        myvariable: "default"
      when: not myvariable

    - debug:
       var=myvariable

Hope that helps. I am not sure if you can construct variables dynamically and do this in an iterator. But you could also write a small python code or any other language and plug it into ansible

I know this has several answers, but none of these really helped me. I found [this article][1] which explains why my sticky wasn't operating as expected.

Basically, you cannot use position: sticky; on <thead> or <tr> elements. However, they can be used on <th>.

The minimum code I needed to make it work is as follows:

table {
  text-align: left;
  position: relative;
}

th {
  background: white;
  position: sticky;
  top: 0;
}

With the table set to relative the <th> can be set to sticky, with the top at 0 [1]: https://css-tricks.com/position-sticky-and-table-headers/

NOTE: It's necessary to wrap the table with a div with max-height:

<div id="managerTable" >
...
</div>

where:

#managerTable {
    max-height: 500px;
    overflow: auto;
}

Public SUB test()
    Dim mdate As Date
    mdate = now()
    MsgBox (Round(CDbl(mdate), 0))
End SUB

@xtrem's answer is good, but I think the toFixed and the makePercentage are common use. Define two functions, and we can use that at everywhere.

const R = require('ramda')
const RA = require('ramda-adjunct')

const fix = R.invoker(1, 'toFixed')(2)

const makePercentage = R.when(
  RA.isNotNil,
  R.compose(R.flip(R.concat)('%'), fix, R.multiply(100)),
)

let a = 0.9988
let b = null

makePercentage(b) // -> null
makePercentage(a) // -> ?????99.88%?????

I've implemented a number of good, short and fast Pseudorandom number generator (PRNG) functions in plain JavaScript. All of them can be seeded and provide good quality numbers.

First of all, take care to initialize your PRNGs properly. Most of the generators below have no built-in seed generating procedure (for sake of simplicity), but accept one or more 32-bit values as the initial state of the PRNG. Similar seeds (e.g. a simple seed of 1 and 2) can cause correlations in weaker PRNGs, resulting in the output having similar properties (such as randomly generated levels being similar). To avoid this, it is best practice to initialize PRNGs with a well-distributed seed.

Thankfully, hash functions are very good at generating seeds for PRNGs from short strings. A good hash function will generate very different results even when two strings are similar. Here's an example based on MurmurHash3's mixing function:

function xmur3(str) {
    for(var i = 0, h = 1779033703 ^ str.length; i < str.length; i++)
        h = Math.imul(h ^ str.charCodeAt(i), 3432918353),
        h = h << 13 | h >>> 19;
    return function() {
        h = Math.imul(h ^ h >>> 16, 2246822507);
        h = Math.imul(h ^ h >>> 13, 3266489909);
        return (h ^= h >>> 16) >>> 0;
    }
}

Each subsequent call to the return function of xmur3 produces a new "random" 32-bit hash value to be used as a seed in a PRNG. Here's how you might use it:

// Create xmur3 state:
var seed = xmur3("apples");
// Output four 32-bit hashes to provide the seed for sfc32.
var rand = sfc32(seed(), seed(), seed(), seed());

// Output one 32-bit hash to provide the seed for mulberry32.
var rand = mulberry32(seed());

// Obtain sequential random numbers like so:
rand();
rand();

Alternatively, simply choose some dummy data to pad the seed with, and advance the generator a few times (12-20 iterations) to mix the initial state thoroughly. This is often seen in reference implementations of PRNGs, but it does limit the number of initial states.

var seed = 1337 ^ 0xDEADBEEF; // 32-bit seed with optional XOR value
// Pad seed with Phi, Pi and E.
// https://en.wikipedia.org/wiki/Nothing-up-my-sleeve_number
var rand = sfc32(0x9E3779B9, 0x243F6A88, 0xB7E15162, seed);
for (var i = 0; i < 15; i++) rand();

The output of these PRNG functions produce a positive 32-bit number (0 to 2³²-1) which is then converted to a floating-point number between 0-1 (0 inclusive, 1 exclusive) equivalent to Math.random(), if you want random numbers of a specific range, read this article on MDN. If you only want the raw bits, simply remove the final division operation.

Another thing to note are the limitations of JS. Numbers can only represent whole integers up to 53-bit resolution. And when using bitwise operations, this is reduced to 32. This makes it difficult to implement algorithms written in C or C++, that use 64-bit numbers. Porting 64-bit code requires shims that can drastically reduce performance. So for the sake of simplicity and efficiency, I've only considered algorithms that use 32-bit math, as it is directly compatible with JS.

Now, onward to the the generators. (I maintain the full list with references here)

sfc32 (Simple Fast Counter)

sfc32 is part of the PractRand random number testing suite (which it passes of course). sfc32 has a 128-bit state and is very fast in JS.

function sfc32(a, b, c, d) {
    return function() {
      a >>>= 0; b >>>= 0; c >>>= 0; d >>>= 0; 
      var t = (a + b) | 0;
      a = b ^ b >>> 9;
      b = c + (c << 3) | 0;
      c = (c << 21 | c >>> 11);
      d = d + 1 | 0;
      t = t + d | 0;
      c = c + t | 0;
      return (t >>> 0) / 4294967296;
    }
}

Mulberry32

Mulberry32 is a simple generator with a 32-bit state, but is extremely fast and has good quality (author states it passes all tests of gjrand testing suite and has a full 2³² period, but I haven't verified).

function mulberry32(a) {
    return function() {
      var t = a += 0x6D2B79F5;
      t = Math.imul(t ^ t >>> 15, t | 1);
      t ^= t + Math.imul(t ^ t >>> 7, t | 61);
      return ((t ^ t >>> 14) >>> 0) / 4294967296;
    }
}

I would recommend this if you just need a simple but decent PRNG and don't need billions of random numbers (see Birthday problem).

xoshiro128**

As of May 2018, xoshiro128** is the new member of the Xorshift family, by Vigna & Blackman (professor Vigna was also responsible for the Xorshift128+ algorithm powering most Math.random implementations under the hood). It is the fastest generator that offers a 128-bit state.

function xoshiro128ss(a, b, c, d) {
    return function() {
        var t = b << 9, r = a * 5; r = (r << 7 | r >>> 25) * 9;
        c ^= a; d ^= b;
        b ^= c; a ^= d; c ^= t;
        d = d << 11 | d >>> 21;
        return (r >>> 0) / 4294967296;
    }
}

The authors claim it passes randomness tests well (albeit with caveats). Other researchers have pointed out that fails some tests in TestU01 (particularly LinearComp and BinaryRank). In practice, it should not cause issues when floats are used (such as these implementations), but may cause issues if relying on the raw low bits.

JSF (Jenkins' Small Fast)

This is JSF or 'smallprng' by Bob Jenkins (2007), the guy who made ISAAC and SpookyHash. It passes PractRand tests and should be quite fast, although not as fast as SFC.

function jsf32(a, b, c, d) {
    return function() {
        a |= 0; b |= 0; c |= 0; d |= 0;
        var t = a - (b << 27 | b >>> 5) | 0;
        a = b ^ (c << 17 | c >>> 15);
        b = c + d | 0;
        c = d + t | 0;
        d = a + t | 0;
        return (d >>> 0) / 4294967296;
    }
}

LCG (aka Lehmer/Park-Miller RNG or MCG)

LCG is extremely fast and simple, but the quality of its randomness is so low, that improper use can actually cause bugs in your program! Nonetheless, it is significantly better than some answers suggesting to use Math.sin or Math.PI! It's a one-liner though, which is nice :).

var LCG=s=>()=>(2**31-1&(s=Math.imul(48271,s)))/2**31;

This implementation is called the minimal standard RNG as proposed by Park–Miller in 1988 & 1993 and implemented in C++11 as minstd_rand. Keep in mind that the state is 31-bit (31 bits give 2 billion possible states, 32 bits give double that). This is the very type of PRNG that others are trying to replace!

It will work, but I wouldn't use it unless you really need speed and don't care about randomness quality (what is random anyway?). Great for a game jam or a demo or something. LCGs suffer from seed correlations, so it is best to discard the first result of an LCG. And if you insist on using an LCG, adding an increment value may improve results, but it is probably an exercise in futility when much better options exist.

There seems to be other multipliers offering a 32-bit state (increased state-space):

var LCG=s=>()=>(s=Math.imul(741103597,s)>>>0)/2**32;
var LCG=s=>()=>(s=Math.imul(1597334677,s)>>>0)/2**32;

These LCG values are from: P. L'Ecuyer: A table of Linear Congruential Generators of different sizes and good lattice structure, April 30 1997.

Here I am going to explain not only the GROUP clause use, but also the Aggregate functions use.

The GROUP BY clause is used in conjunction with the aggregate functions to group the result-set by one or more columns. e.g.:

-- GROUP BY with one parameter:
SELECT column_name, AGGREGATE_FUNCTION(column_name)
FROM table_name
WHERE column_name operator value
GROUP BY column_name;

-- GROUP BY with two parameters:
SELECT
    column_name1,
    column_name2,
    AGGREGATE_FUNCTION(column_name3)
FROM
    table_name
GROUP BY
    column_name1,
    column_name2;

Remember this order:

1. SELECT (is used to select data from a database)

2. FROM (clause is used to list the tables)

3. WHERE (clause is used to filter records)

4. GROUP BY (clause can be used in a SELECT statement to collect data across multiple records and group the results by one or more columns)

5. HAVING (clause is used in combination with the GROUP BY clause to restrict the groups of returned rows to only those whose the condition is TRUE)

6. ORDER BY (keyword is used to sort the result-set)

You can use all of these if you are using aggregate functions, and this is the order that they must be set, otherwise you can get an error.

Aggregate Functions are:

MIN() returns the smallest value in a given column

MAX() returns the maximum value in a given column.

SUM() returns the sum of the numeric values in a given column

AVG() returns the average value of a given column

COUNT() returns the total number of values in a given column

COUNT(*) returns the number of rows in a table

SQL script examples about using aggregate functions:

Let's say we need to find the sale orders whose total sale is greater than $950. We combine the HAVING clause and the GROUP BY clause to accomplish this:

SELECT 
    orderId, SUM(unitPrice * qty) Total
FROM
    OrderDetails
GROUP BY orderId
HAVING Total > 950;

Counting all orders and grouping them customerID and sorting the result ascendant. We combine the COUNT function and the GROUP BY, ORDER BY clauses and ASC:

SELECT 
    customerId, COUNT(*)
FROM
    Orders
GROUP BY customerId
ORDER BY COUNT(*) ASC;

Retrieve the category that has an average Unit Price greater than $10, using AVG function combine with GROUP BY and HAVING clauses:

SELECT 
    categoryName, AVG(unitPrice)
FROM
    Products p
INNER JOIN
    Categories c ON c.categoryId = p.categoryId
GROUP BY categoryName
HAVING AVG(unitPrice) > 10;

Getting the less expensive product by each category, using the MIN function in a subquery:

SELECT categoryId,
       productId,
       productName,
       unitPrice
FROM Products p1
WHERE unitPrice = (
                SELECT MIN(unitPrice)
                FROM Products p2
                WHERE p2.categoryId = p1.categoryId)

The following statement groups rows with the same values in both categoryId and productId columns:

SELECT 
    categoryId, categoryName, productId, SUM(unitPrice)
FROM
    Products p
INNER JOIN
    Categories c ON c.categoryId = p.categoryId
GROUP BY categoryId, productId

from this example here, you can see the the conversions both ways:

NSString *str=@"5678901234567890";

long long verylong;
NSRange range;
range.length = 15;
range.location = 0;

[[NSScanner scannerWithString:[str substringWithRange:range]] scanLongLong:&verylong];

NSLog(@"long long value %lld",verylong);

First of all, when you put that code in applicationDidFinishLaunching, it might be the case that controllers instantiated from Interface Builder are not yet linked to your application (so "red" and "blue" are still nil).

But to answer your initial question, what you're doing wrong is that you're calling dismissModalViewControllerAnimated: on the wrong controller! It should be like this:

[blue presentModalViewController:red animated:YES];
[red dismissModalViewControllerAnimated:YES];

Usually the "red" controller should decide to dismiss himself at some point (maybe when a "cancel" button is clicked). Then the "red" controller could call the method on self:

[self dismissModalViewControllerAnimated:YES];

If it still doesn't work, it might have something to do with the fact that the controller is presented in an animation fashion, so you might not be allowed to dismiss the controller so soon after presenting it.

For those not interested in USB debugging or using adb there is an easier solution. In Android 6 (Not sure about prior version) there is an option under developer tools: Take Bug Report

Clicking this option will prepare a bug report and prompt you to save it to drive or have it sent in email.

I found this to be the easiest way to get logs. I don't like to turn on USB debugging.

System.Data.SqlClient is the .NET Framework Data Provider for SQL Server. ie .NET library for SQL Server.

I don't know where providerName=SqlServer comes from. Could you be getting this confused with the provider keyword in your connection string? (I know I was :) )

In the web.config you should have the System.Data.SqlClient as the value of the providerName attribute. It is the .NET Framework Data Provider you are using.

<connectionStrings>
   <add 
      name="LocalSqlServer" 
      connectionString="data source=.\SQLEXPRESS;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|aspnetdb.mdf;User Instance=true" 
      providerName="System.Data.SqlClient"
   />
</connectionStrings>

See http://msdn.microsoft.com/en-US/library/htw9h4z3(v=VS.80).aspx

Another way of escaping the apostrophe is to write a string literal:

insert into Person (First, Last) values (q'[Joe]', q'[O'Brien]')

This is a better approach, because:

1. Imagine you have an Excel list with 1000's of names you want to upload to your database. You may simply create a formula to generate 1000's of INSERT statements with your cell contents instead of looking manually for apostrophes.

2. It works for other escape characters too. For example loading a Regex pattern value, i.e. ^( *)(P|N)?( *)|( *)((<|>)\d\d?)?( *)|( )(((?i)(in|not in)(?-i) ?(('[^']+')(, ?'[^']+'))))?( *)$ into a table.

Thank Mathias Lin, tested and it works!

In addition, sample implementation of Mathias's method in activity can be as follows.

public class DirectionMapActivity extends MapActivity {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.directionmap);

        String locationProvider = LocationManager.NETWORK_PROVIDER;
        Location lastKnownLocation = locationManager.getLastKnownLocation(locationProvider);

Do you have the SSH2 extension available?

Docs: http://www.php.net/manual/en/function.ssh2-exec.php

$connection = ssh2_connect('shell.example.com', 22);
ssh2_auth_password($connection, 'username', 'password');

$stream = ssh2_exec($connection, '/usr/local/bin/php -i');

It is also very important to distinguish a SENDING multicast socket from a RECEIVING multicast socket.

I agree with all the answers above regarding RECEIVING multicast sockets. The OP noted that binding a RECEIVING socket to an interface did not help. However, it is necessary to bind a multicast SENDING socket to an interface.

For a SENDING multicast socket on a multi-homed server, it is very important to create a separate socket for each interface you want to send to. A bound SENDING socket should be created for each interface.

  // This is a fix for that bug that causes Servers to pop offline/online.
  // Servers will intermittently pop offline/online for 10 seconds or so.
  // The bug only happens if the machine had a DHCP gateway, and the gateway is no longer accessible.
  // After several minutes, the route to the DHCP gateway may timeout, at which
  // point the pingponging stops.
  // You need 3 machines, Client machine, server A, and server B
  // Client has both ethernets connected, and both ethernets receiving CITP pings (machine A pinging to en0, machine B pinging to en1)
  // Now turn off the ping from machine B (en1), but leave the network connected.
  // You will notice that the machine transmitting on the interface with
  // the DHCP gateway will fail sendto() with errno 'No route to host'
  if ( theErr == 0 )
  {
     // inspired by 'ping -b' option in man page:      
     //      -b boundif
     //             Bind the socket to interface boundif for sending.
     struct sockaddr_in bindInterfaceAddr;
     bzero(&bindInterfaceAddr, sizeof(bindInterfaceAddr));
     bindInterfaceAddr.sin_len = sizeof(bindInterfaceAddr);
     bindInterfaceAddr.sin_family = AF_INET;
     bindInterfaceAddr.sin_addr.s_addr = htonl(interfaceipaddr);
     bindInterfaceAddr.sin_port = 0; // Allow the kernel to choose a random port number by passing in 0 for the port.
     theErr = bind(mSendSocketID, (struct sockaddr *)&bindInterfaceAddr, sizeof(bindInterfaceAddr));
     struct sockaddr_in serverAddress;
     int namelen = sizeof(serverAddress);  
     if (getsockname(mSendSocketID, (struct sockaddr *)&serverAddress, (socklen_t *)&namelen) < 0) {
        DLogErr(@"ERROR Publishing service... getsockname err");
     }
     else
     {
        DLog( @"socket %d bind, %@ port %d", mSendSocketID, [NSString stringFromIPAddress:htonl(serverAddress.sin_addr.s_addr)], htons(serverAddress.sin_port) );
     }

Without this fix, multicast sending will intermittently get sendto() errno 'No route to host'. If anyone can shed light on why unplugging a DHCP gateway causes Mac OS X multicast SENDING sockets to get confused, I would love to hear it.

Strange answers here! You can insert strings into other strings easily with sprintf [link to documentation]. The function is extremely powerful and can handle multiple elements and other data types too.

$color = 'green';
sprintf('I like %s apples.', $color);

gives you the string

I like green apples.

Some of you have highly over complicated this. I found this to be extremely simple.

1) Create a database with the same name as your .bak file database name !Important

2) right click the database | Tasks > Restore > Database

3) Under "Source for restore" select "From Device"

4) Select .bak file

5) Select the check box for the database in the gridview below

6) Under "Select a Page" on the right Select "Options"

7) Select the checkbox labeled "Preserve the replication settings(WITH KEEP_REPLICATION)

Now Go back to the General page and click OK to restore the database...That is it.

You could use the ones on CodePlex or http://www.enterprisedt.com/general/press/20060818.html

<select>
  <option value="" disabled selected hidden>Select an Option</option>
  <option value="one">Option 1</option>
  <option value="two">Option 2</option>
</select>

def send_email(user, pwd, recipient, subject, body):
    import smtplib

    FROM = user
    TO = recipient if isinstance(recipient, list) else [recipient]
    SUBJECT = subject
    TEXT = body

    # Prepare actual message
    message = """From: %s\nTo: %s\nSubject: %s\n\n%s
    """ % (FROM, ", ".join(TO), SUBJECT, TEXT)
    try:
        server = smtplib.SMTP("smtp.gmail.com", 587)
        server.ehlo()
        server.starttls()
        server.login(user, pwd)
        server.sendmail(FROM, TO, message)
        server.close()
        print 'successfully sent the mail'
    except:
        print "failed to send mail"

if you want to use Port 465 you have to create an SMTP_SSL object:

# SMTP_SSL Example
server_ssl = smtplib.SMTP_SSL("smtp.gmail.com", 465)
server_ssl.ehlo() # optional, called by login()
server_ssl.login(gmail_user, gmail_pwd)  
# ssl server doesn't support or need tls, so don't call server_ssl.starttls() 
server_ssl.sendmail(FROM, TO, message)
#server_ssl.quit()
server_ssl.close()
print 'successfully sent the mail'

You call both event listeners using .on() then use a if inside the function:

$(function(){
  $('#searchButton').on('keypress click', function(e){
    var search = $('#usersSearch').val();
    if (e.which === 13 || e.type === 'click') {
      $.post('../searchusers.php', {search: search}, function (response) {
        $('#userSearchResultsTable').html(response);
      });
    }
  });
});

You don't need to convert to decimal; you can also enter 46 23S, 115 22E. You can add seconds after the minutes, also separated by a space.

The following code works fine:

@using (Html.BeginForm("Upload", "Upload", FormMethod.Post, 
                                      new { enctype = "multipart/form-data" }))
{
    @Html.ValidationSummary(true)
    <fieldset>
        Select a file <input type="file" name="file" />
        <input type="submit" value="Upload" />
    </fieldset>
}

and generates as expected:

<form action="/Upload/Upload" enctype="multipart/form-data" method="post">    
    <fieldset>
        Select a file <input type="file" name="file" />
        <input type="submit" value="Upload" />
    </fieldset>
</form>

On the other hand if you are writing this code inside the context of other server side construct such as an if or foreach you should remove the @ before the using. For example:

@if (SomeCondition)
{
    using (Html.BeginForm("Upload", "Upload", FormMethod.Post, 
                                      new { enctype = "multipart/form-data" }))
    {
        @Html.ValidationSummary(true)
        <fieldset>
            Select a file <input type="file" name="file" />
            <input type="submit" value="Upload" />
        </fieldset>
    }
}

As far as your server side code is concerned, here's how to proceed:

[HttpPost]
public ActionResult Upload(HttpPostedFileBase file) 
{
    if (file != null && file.ContentLength > 0) 
    {
        var fileName = Path.GetFileName(file.FileName);
        var path = Path.Combine(Server.MapPath("~/content/pics"), fileName);
        file.SaveAs(path);
    }
    return RedirectToAction("Upload");
}

The second option is feasible also if you're using safe updates mode (and you're getting an error indicating that you've tried to update a table without a WHERE that uses a KEY column), by adding:

UPDATE TableB  
SET TableB.value = (  
SELECT TableA.value  
    FROM TableA  
    WHERE TableA.name = TableB.name  
)  
**where TableB.id < X**  
;

One of the most straightforward ways to do it is

git for-each-ref --format='%(refname:short)' refs/heads/

This works perfectly for scripts as well.

Interestingly, it seems that in Windows Embedded Compact 7, you cannot specify a title string. The first parameter has to be the command or program.

this will prevent any zoom action by the user in ios safari and also prevent the "zoom to tabs" feature:

document.addEventListener('gesturestart', function(e) {
    e.preventDefault();
    // special hack to prevent zoom-to-tabs gesture in safari
    document.body.style.zoom = 0.99;
});

document.addEventListener('gesturechange', function(e) {
    e.preventDefault();
    // special hack to prevent zoom-to-tabs gesture in safari
    document.body.style.zoom = 0.99;
});

It's way late but you should look at this. Not CLI I know but still worth just knocking out a little shell script to do what you need:

https://pypi.org/project/aws-list-all/

It's a python library that in it's own words:

"Project description List all resources in an AWS account, all regions, all services(*). Writes JSON files for further processing.

(*) No guarantees for completeness. Use billing alerts if you are worried about costs."

Use the set built-in to load up the $@ array:

IN="[email protected];[email protected]"
IFS=';'; set $IN; IFS=$' \t\n'

Then, let the party begin:

echo $#
for a; do echo $a; done
ADDR1=$1 ADDR2=$2

You can use the following command:
:%s/^V^M//g
where the '^' means use CTRL key.

call srand(sameSeed) before calling rand(). More details here.

..and to detect a change in resolution to handle it (once you're using Docking and Anchoring like SwDevMan81 suggested) use the SystemEvents.DisplaySettingsChanged event in Microsoft.Win32.

With jQuery, I've done it this way:

function checkKey(e){
     switch (e.keyCode) {
        case 40:
            alert('down');
            break;
        case 38:
            alert('up');
            break;
        case 37:
            alert('left');
            break;
        case 39:
            alert('right');
            break;
        default:
            alert('???');  
            }      
}

if ($.browser.mozilla) {
    $(document).keypress (checkKey);
} else {
    $(document).keydown (checkKey);
}

Also, try these plugins, which looks like they do all that work for you:

I Would like to add how the pythonic key function works while sorting :

Decorate-Sort-Undecorate Design Pattern :

Python’s support for a key function when sorting is implemented using what is known as the decorate-sort-undecorate design pattern.

It proceeds in 3 steps:

1. Each element of the list is temporarily replaced with a “decorated” version that includes the result of the key function applied to the element.

2. The list is sorted based upon the natural order of the keys.

3. The decorated elements are replaced by the original elements.

Key parameter to specify a function to be called on each list element prior to making comparisons. docs

I would like to know what exactly is the difference between querySelector and querySelectorAll against getElementsByClassName and getElementById?

The syntax and the browser support.

querySelector is more useful when you want to use more complex selectors.

e.g. All list items descended from an element that is a member of the foo class: .foo li

document.querySelector("#view:_id1:inputText1") it doesn't work. But writing document.getElementById("view:_id1:inputText1") works. Any ideas why?

The : character has special meaning inside a selector. You have to escape it. (The selector escape character has special meaning in a JS string too, so you have to escape that too).

document.querySelector("#view\\:_id1\\:inputText1")

Use a vertical bar (|) for "or".

As you've already noticed svn log command ran without any arguments shows all log messages that relate to the URL you specify or to the working copy folder where you run the command.

You can always refine/limit the svn log results:

• svn log --limit NUM will show only the first NUM of revisions,
• svn log --revision REV1(:REV2) will show the log message for REV1 revision or for REV1 -- REV2 range,
• svn log --search will show revisions that match the search pattern you specify (the command is available in Subversion 1.8 and newer client). You can search by
  • revision's author (i.e. committers username),
  • date when the revision was committed,
  • revision comment text (log message),
  • list of paths changed in revision.

  int a = srand(time(NULL));

The prototype for srand is void srand(unsigned int) (provided you included <stdlib.h>).
This means it returns nothing ... but you're using the value it returns (???) to assign, by initialization, to a.

Edit: this is what you need to do:

#include <stdlib.h> /* srand(), rand() */
#include <time.h>   /* time() */

#define ARRAY_SIZE 1024

void getdata(int arr[], int n)
{
    for (int i = 0; i < n; i++)
    {
        arr[i] = rand();
    }
}

int main(void)
{
    int arr[ARRAY_SIZE];
    srand(time(0));
    getdata(arr, ARRAY_SIZE);
    /* ... */
}

NameValueCollection n = Request.QueryString;

if (n.HasKeys())
   {
       //something
   }

Return Value Type: System.Boolean true if the NameValueCollection contains keys that are not null; otherwise, false. LINK

As a general rule, you can use Database_Default collation so you don't need to figure out which one to use. However, I strongly suggest reading Simons Liew's excellent article Understanding the COLLATE DATABASE_DEFAULT clause in SQL Server

SELECT *
  FROM [FAEB].[dbo].[ExportaComisiones] AS f
  JOIN [zCredifiel].[dbo].[optPerson] AS p
  ON (p.vTreasuryId = f.RFC) COLLATE Database_Default

If jQuery is available, angular.element is an alias for the jQuery function.

var app = angular.module('myApp',[]);

app.controller('Ctrl', function($scope) {

    $scope.click=function(){

      angular.element('#div1').addClass("alpha");
    };
});
<div id='div1'>Text</div>
<button ng-click="click()">action</button>

Use this to set the orientation of the screen:

setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);

or

setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);

and don't forget to add this to your manifest:

android:configChanges = "orientation"

I think you must use rawurlencode() instead urlencode() for your purpose.

sample

$image = 'some images.jpg';
$url   = 'http://example.com/'

With urlencode($str) will result

echo $url.urlencode($image); //http://example.com/some+images.jpg

its not change to %20 at all

but with rawurlencode($image) will produce

echo $url.rawurlencode(basename($image)); //http://example.com/some%20images.jpg

You need a dict:

my_dict = {'cheese': 'cake'}

Example code (from the docs):

>>> a = dict(one=1, two=2, three=3)
>>> b = {'one': 1, 'two': 2, 'three': 3}
>>> c = dict(zip(['one', 'two', 'three'], [1, 2, 3]))
>>> d = dict([('two', 2), ('one', 1), ('three', 3)])
>>> e = dict({'three': 3, 'one': 1, 'two': 2})
>>> a == b == c == d == e
True

You can read more about dictionaries here.

Trying to uninstall Python with

brew uninstall python

will not remove the natively installed Python but rather the version installed with brew.

You can remove the entire line below:

 .map((res: Response) => res.json());

No need to use the map method at all.

The first part of your question is easy. As already pointed out, cut accepts omission of either the starting or the ending index of a column range, interpreting this as meaning either “from the start to column n (inclusive)” or “from column n (inclusive) to the end,” respectively:

$ printf 'this:is:a:test' | cut -d: -f-2
this:is
$ printf 'this:is:a:test' | cut -d: -f3-
a:test

It also supports combining ranges. If you want, e.g., the first 3 and the last 2 columns in a row of 7 columns:

$ printf 'foo:bar:baz:qux:quz:quux:quuz' | cut -d: -f-3,6-
foo:bar:baz:quux:quuz

However, the second part of your question can be a bit trickier depending on what kind of input you’re expecting. If by “last n columns” you mean “last n columns (regardless of their indices in the overall row)” (i.e. because you don’t necessarily know how many columns you’re going to find in advance) then sadly this is not possible to accomplish using cut alone. In order to effectively use cut to pull out “the last n columns” in each line, the total number of columns present in each line must be known beforehand, and each line must be consistent in the number of columns it contains.

If you do not know how many “columns” may be present in each line (e.g. because you’re working with input that is not strictly tabular), then you’ll have to use something like awk instead. E.g., to use awk to pull out the last 2 “columns” (awk calls them fields, the number of which can vary per line) from each line of input:

$ printf '/a\n/a/b\n/a/b/c\n/a/b/c/d\n' | awk -F/ '{print $(NF-1) FS $(NF)}'
/a
a/b
b/c
c/d

It behaves the way you want if called as a function:

>>> def test():
...     a = iter(list(range(10)))
...     for i in a:
...         print(i)
...         next(a)
... 
>>> test()
0
2
4
6
8

import platform
platform.architecture()

From the Python docs:

Queries the given executable (defaults to the Python interpreter binary) for various architecture information.

Returns a tuple (bits, linkage) which contain information about the bit architecture and the linkage format used for the executable. Both values are returned as strings.

Answer above is not suitable for complicate Linq expression. All you need is:

// set up the "main query"
var test = from p in _db.test select _db.test;
// if str1 is not null, add a where-condition
if(str1 != null)
{
    test = test.Where(p => p.test == str);
}

If you're using npm >=1.0, you can use npm link <global-package> to create a local link to a package already installed globally. (Caveat: The OS must support symlinks.)

However, this doesn't come without its problems.

npm link is a development tool. It's awesome for managing packages on your local development box. But deploying with npm link is basically asking for problems, since it makes it super easy to update things without realizing it.

As an alternative, you can install the packages locally as well as globally.

For additional information, see

• https://nodejs.org/en/blog/npm/npm-1-0-link/
• https://nodejs.org/en/blog/npm/npm-1-0-global-vs-local-installation/

A simpler way is

ggplot(data=df, aes(x=xvar, y=yvar)) + 
geom_point()

ggsave(path = path, width = width, height = height, device='tiff', dpi=700)

Another variation of answer suggested by JAR.JAR.beans

(Math.random()*1e32).toString(36)

By changing multiplicator 1e32 you can change length of random string.

In my case the only way I could keep using GetGroups() without any expcetion was adding the user (USER_WITH_PERMISSION) to the group which has permission to read the AD (Active Directory). It's extremely essential to construct the PrincipalContext passing this user and password.

var pc = new PrincipalContext(ContextType.Domain, domain, "USER_WITH_PERMISSION", "PASS");
var user = UserPrincipal.FindByIdentity(pc, IdentityType.SamAccountName, userName);
var groups = user.GetGroups();

Steps you may follow inside Active Directory to get it working:

1. Into Active Directory create a group (or take one) and under secutiry tab add "Windows Authorization Access Group"
2. Click on "Advanced" button
3. Select "Windows Authorization Access Group" and click on "View"
4. Check "Read tokenGroupsGlobalAndUniversal"
5. Locate the desired user and add to the group you created (taken) from the first step

Its an injector error. You may have use lots of JavaScript files so the injector may be missing.

Some are here:

var app = angular.module('app', 
    ['ngSanitize', 'ui.router', 'pascalprecht.translate', 'ngResource', 
     'ngMaterial', 'angularMoment','md.data.table', 'angularFileUpload', 
     'ngMessages', 'ui.utils.masks', 'angular-sortable-view',          
     'mdPickers','ngDraggable','as.sortable', 'ngAnimate', 'ngTouch']
);

Please check the injector you need to insert in your app.js

Truncate table is faster than delete * from XXX. Delete is slow because it works one row at a time. There are a few situations where truncate doesn't work, which you can read about on MSDN.

Very late answer for someone that, like me, comes here looking for a simple and quick answer.

In Python 2.7 you could use an additional parameter msg to add information to the error message like this:

self.assertEqual(f.bar(t2), 2, msg='{0}, {1}'.format(t1, t2))

For any of you still having problems as of Sept. 2012, go here: http://support.microsoft.com/kb/2527041 ...and grab the SQLManagementStudio_x(32|64)_ENU.exe (if you've already installed SQL Server 2008 Express R2), or SQL Server 2008 Express R2 with Tools, i.e. SQLEXPRWT_x64_ENU.exe or SQLEXPRWT_x32_ENU.exe (if you haven't).

From there, follow similar instructions as above (i.e. use the "Perform new installation and add shared features" selection, as "Management Tools - Basic" is considered a "shared feature"), if you've already installed SQL Server Express 2008 R2 (as I had). And if you haven't done that yet, then of course you're going to follow this way as you need to install the new instance anyway.

This solved things for me, and hopefully it will for you, too!

The difference between substring and slice - is how they work with negative and overlooking lines abroad arguments:

substring (start, end)

Negative arguments are interpreted as zero. Too large values ??are truncated to the length of the string:   alert ( "testme" .substring (-2)); // "testme", -2 becomes 0

Furthermore, if start > end, the arguments are interchanged, i.e. plot line returns between the start and end:

alert ( "testme" .substring (4, -1)); // "test"
// -1 Becomes 0 -> got substring (4, 0)
// 4> 0, so that the arguments are swapped -> substring (0, 4) = "test"

slice

Negative values ??are measured from the end of the line:

alert ( "testme" .slice (-2)); // "me", from the end position 2
alert ( "testme" .slice (1, -1)); // "estm", from the first position to the one at the end.

It is much more convenient than the strange logic substring.

A negative value of the first parameter to substr supported in all browsers except IE8-.

If the choice of one of these three methods, for use in most situations - it will be slice: negative arguments and it maintains and operates most obvious.

You could decorate the property you wish controlling its name with the [JsonProperty] attribute which allows you to specify a different name:

using Newtonsoft.Json;
// ...

[JsonProperty(PropertyName = "FooBar")]
public string Foo { get; set; }

MyList.Add("HELLO");
MyList.Add("WORLD");

listBox1.DataSource = MyList;

I like this method (it looks a little cleaner):

text = text.replace(new RegExp("cat","g"), "dog"); 

No this is not possible. The only solution will be to have regular backups. This is very important.

Just type npm version in your command line and it will display all the version details about node, npm, v8 engine etc.

This happens when you have Cors option configured at multiple locations. In my case I had it at the controller level as well as in the Startup.Auth.cs/ConfigureAuth.

My understanding is if you want it application wide then just configure it under Startup.Auth.cs/ConfigureAuth like this...You will need reference to Microsoft.Owin.Cors

public void ConfigureAuth(IAppBuilder app)
        {
          app.UseCors(CorsOptions.AllowAll);

If you rather keep it at the controller level then you may just insert at the Controller level.

[EnableCors("http://localhost:24589", "*", "*")]
    public class ProductsController : ApiController
    {
        ProductRepository _prodRepo;

Make sure that each Application Pool in IIS, under Advanced Settings has Enable 32 bit Applications set to True

Basically, tree conflicts arise if there is some restructure in the folder structure on the branch. You need to delete the conflict folder and use svn clean once. Hope this solves your conflict.

You can create the .p8 file for it in https://developer.apple.com/account/

Then go to Certificates, Identifiers & Profiles > Keys > add

Select Apple Push Notification service (APNs), put a Key Name (whatever).

Then click on "continue", after "register" and you get it and you can download it.

This is easier:

location.href = 'http://address.com';

Or

location.replace('http://address.com'); // <-- No history saved.

Which specific index? If you want 'Add New' to be first on the dropdownlist you can add it though the code like this:

<asp:DropDownList ID="DropDownList1" AppendDataBoundItems="true" runat="server">
     <asp:ListItem Text="Add New" Value="0" />
</asp:DropDownList>

If you want to add it at a different index, maybe the last then try:

ListItem lst = new ListItem ( "Add New" , "0" );

DropDownList1.Items.Insert( DropDownList1.Items.Count-1 ,lst);

The idea that you need to get the reference to the object that is contained inside a Set object is common. It can be archived by 2 ways:

1. Use HashSet as you wanted, then:

   public Object getObjectReference(HashSet<Xobject> set, Xobject obj) {
       if (set.contains(obj)) {
           for (Xobject o : set) {
               if (obj.equals(o))
                   return o;
           }
       }
       return null;
   }
   

For this approach to work, you need to override both hashCode() and equals(Object o) methods In the worst scenario we have O(n)

2. Second approach is to use TreeSet

   public Object getObjectReference(TreeSet<Xobject> set, Xobject obj) {
       if (set.contains(obj)) {
           return set.floor(obj);
       }
       return null;
   }
   

This approach gives O(log(n)), more efficient. You don't need to override hashCode for this approach but you have to implement Comparable interface. ( define function compareTo(Object o)).

It's possible, use the structure below:

<li><a><span></span></a></li>
<li><a><span></span></a></li>

etc...

Where the <li> contains an <a> anchor tag that contains a span as shown above. Then insert the following css:

• LI get position: relative;
• Give <a> tag a height, width
• Set <span> width & height to 100%, so that both <a> and <span> have same dimensions
• Both <a> and <span> get position: relative;.
• Assign the same background image to each element
• <a> tag will have the 'OFF' background-position, and the <span> will have the 'ON' background-poisiton.
• For 'OFF' state use opacity 0 for <span>
• For 'ON' :hover state use opacity 1 for <span>
• Set the -webkit or -moz transition on the <span> element

You'll have the ability to use the transition effect while still defaulting to the old background-position swap. Don't forget to insert IE alpha filter.

Other answers are great. This is another way it can be done.

1. Here I use SizedBox.expand() to fill available space and for passing tight constraints for its children (Container).
2. BoxFit.cover enum to Zoom the image and cover whole screen

 Widget build(BuildContext context) {
    return Scaffold(
      body: SizedBox.expand( // -> 01
        child: Container(
          decoration: BoxDecoration(
            image: DecorationImage(
              image: NetworkImage('https://flutter.github.io/assets-for-api-docs/assets/widgets/owl-2.jpg'),
              fit: BoxFit.cover,    // -> 02
            ),
          ),
        ),
      ),
    );
  }

Bash

To get list of keys in Bash, follow the these steps.

First, define the following wrapper function to make it simple to use (copy and paste into shell):

function memcmd() {
  exec {memcache}<>/dev/tcp/localhost/11211
  printf "%s\n%s\n" "$*" quit >&${memcache}
  cat <&${memcache}
}

Memcached 1.4.31 and above

You can use lru_crawler metadump all command to dump (most of) the metadata for (all of) the items in the cache.

As opposed to cachedump, it does not cause severe performance problems and has no limits on the amount of keys that can be dumped.

Example command by using the previously defined function:

memcmd lru_crawler metadump all

See: ReleaseNotes1431.

Memcached 1.4.30 and below

Get list of slabs by using items statistics command, e.g.:

memcmd stats items

For each slub class, you can get list of items by specifying slub id along with limit number (0 - unlimited):

memcmd stats cachedump 1 0
memcmd stats cachedump 2 0
memcmd stats cachedump 3 0
memcmd stats cachedump 4 0
...

^{Note: You need to do this for each memcached server.}

To list all the keys from all stubs, here is the one-liner (per one server):

for id in $(memcmd stats items | grep -o ":[0-9]\+:" | tr -d : | sort -nu); do
    memcmd stats cachedump $id 0
done

^{Note: The above command could cause severe performance problems while accessing the items, so it's not advised to run on live.}

Notes:

stats cachedump only dumps the HOT_LRU (IIRC?), which is managed by a background thread as activity happens. This means under a new enough version which the 2Q algo enabled, you'll get snapshot views of what's in just one of the LRU's.

If you want to view everything, lru_crawler metadump 1 (or lru_crawler metadump all) is the new mostly-officially-supported method that will asynchronously dump as many keys as you want. you'll get them out of order but it hits all LRU's, and unless you're deleting/replacing items multiple runs should yield the same results.

If you do Code-First and already have a Database:

public override void Up()
{
    AlterColumn("dbo.MyTable","Id", c =>  c.Guid(nullable: false, identity: true, defaultValueSql: "newsequentialid()"));
}

This is my trigger example:

/************ ROLE ************/_x000D_
drop table if exists `role`;_x000D_
create table `role` (_x000D_
    `id_role` bigint(20) unsigned not null auto_increment,_x000D_
    `date_created` datetime,_x000D_
    `date_deleted` datetime,_x000D_
    `name` varchar(35) not null,_x000D_
    `description` text,_x000D_
    primary key (`id_role`)_x000D_
) comment='';_x000D_
_x000D_
drop trigger if exists `role_date_created`;_x000D_
create trigger `role_date_created` before insert_x000D_
    on `role`_x000D_
    for each row _x000D_
    set new.`date_created` = now();

This is normal (and has nothing to do with Python) because 8.83 cannot be represented exactly as a binary float, just as 1/3 cannot be represented exactly in decimal (0.333333... ad infinitum).

If you want to ensure absolute precision, you need the decimal module:

>>> import decimal
>>> a = decimal.Decimal("8.833333333339")
>>> print(round(a,2))
8.83

It doesn't - the C# compiler does :)

So this code:

string x = "hello";
string y = "there";
string z = "chaps";
string all = x + y + z;

actually gets compiled as:

string x = "hello";
string y = "there";
string z = "chaps";
string all = string.Concat(x, y, z);

(Gah - intervening edit removed other bits accidentally.)

The benefit of the C# compiler noticing that there are multiple string concatenations here is that you don't end up creating an intermediate string of x + y which then needs to be copied again as part of the concatenation of (x + y) and z. Instead, we get it all done in one go.

EDIT: Note that the compiler can't do anything if you concatenate in a loop. For example, this code:

string x = "";
foreach (string y in strings)
{
    x += y;
}

just ends up as equivalent to:

string x = "";
foreach (string y in strings)
{
    x = string.Concat(x, y);
}

... so this does generate a lot of garbage, and it's why you should use a StringBuilder for such cases. I have an article going into more details about the two which will hopefully answer further questions.

We used express' 404 handling approach

// path to the static react build directory    
const frontend = path.join(__dirname, 'react-app/build');

// map the requests to the static react build directory
app.use('/', express.static(frontend));

// all the unknown requests are redirected to the react SPA
app.use(function (req, res, next) {
    res.sendFile(path.join(frontend, 'index.html'));
});

Works like a charm. A live demo is our site

I think you are looking for Return instead of Break. Break is typically used for loops and only breaks from the innermost code block. Use Return to exit a function or script.

... WHERE date_column >='2012-12-25' AND date_column <'2012-12-26' may potentially work better(if you have an index on date_column) than DATE.

I can recommend make pre-init of future index value, this is very usefull in a lot of case like multi work, some export e.t.c.

just create additional User_Seq table: with two fields: id Uniq index and SeqVal nvarchar(1)

and create next SP, and generated ID value from this SP and put to new User row!

Basically reload as in allyourcode's asnwer. But it won't change underlying the code of already instantiated object or referenced functions. Extending from his answer:

#Make a simple function that prints "version 1"
shell1$ echo 'def x(): print "version 1"' > mymodule.py

# Run the module
shell2$ python
>>> import mymodule
>>> mymodule.x()
version 1
>>> x = mymodule.x
>>> x()
version 1
>>> x is mymodule.x
True


# Change mymodule to print "version 2" (without exiting the python REPL)
shell2$ echo 'def x(): print "version 2"' > mymodule.py

# Back in that same python session
>>> reload(mymodule)
<module 'mymodule' from 'mymodule.pyc'>
>>> mymodule.x()
version 2
>>> x()
version 1
>>> x is mymodule.x
False

You will get an error if you try to close/disconnect outside of the method. The best solution is to close the connection in both callbacks in the method. The dummy code is here.

const newTodo = new Todo({text:'cook dinner'});

newTodo.save().then((docs) => {
  console.log('todo saved',docs);
  mongoose.connection.close();
},(e) => {
  console.log('unable to save');
});

There can be many causes to this problem.

My suggestion is to turn on WP_DEBUG in wp-config.php

define('WP_DEBUG', true);

Besides using one of the default formats you can specify any size you want in the unit you specify.

For example:

// Document of 210mm wide and 297mm high
new jsPDF('p', 'mm', [297, 210]);
// Document of 297mm wide and 210mm high
new jsPDF('l', 'mm', [297, 210]);
// Document of 5 inch width and 3 inch high
new jsPDF('l', 'in', [3, 5]);

The 3rd parameter of the constructor can take an array of the dimensions. However they do not correspond to width and height, instead they are long side and short side (or flipped around).

Your 1st parameter (landscape or portrait) determines what becomes the width and the height.

In the sourcecode on GitHub you can see the supported units (relative proportions to pt), and you can also see the default page formats (with their sizes in pt).

You can log process output using below code:

ProcessStartInfo pinfo = new ProcessStartInfo(item);
pinfo.CreateNoWindow = false;
pinfo.UseShellExecute = true;
pinfo.RedirectStandardOutput = true;
pinfo.RedirectStandardInput = true;
pinfo.RedirectStandardError = true;
pinfo.WindowStyle = System.Diagnostics.ProcessWindowStyle.Normal;
var p = Process.Start(pinfo);
p.WaitForExit();
Process process = Process.Start(new ProcessStartInfo((item + '>' + item + ".txt"))
{
    UseShellExecute = false,
    RedirectStandardOutput = true
});
process.WaitForExit();
string output = process.StandardOutput.ReadToEnd();
if (process.ExitCode != 0) { 
}

Use file. Examples:

> file --mime-type image.png
image.png: image/png

> file -b --mime-type image.png
image/png

> file -i FILE_NAME
image.png: image/png; charset=binary

The first answer covers it.

Im guessing that somewhere down the line you may decide to store your info in a different class/structure. In that case you probably wouldn't want the results going in to an array from the split() method.

You didn't ask for it, but I'm bored, so here is an example, hope it's helpful.

This might be the class you write to represent a single person:

class Person {
            public String firstName;
            public String lastName;
            public int id;
            public int age;

      public Person(String firstName, String lastName, int id, int age) {
         this.firstName = firstName;
         this.lastName = lastName;
         this.id = id;
         this.age = age;
      }  
      // Add 'get' and 'set' method if you want to make the attributes private rather than public.
} 

Then, the version of the parsing code you originally posted would look something like this: (This stores them in a LinkedList, you could use something else like a Hashtable, etc..)

try 
{
    String ruta="entrada.al";
    BufferedReader reader = new BufferedReader(new FileReader(ruta));

    LinkedList<Person> list = new LinkedList<Person>();

    String line = null;         
    while ((line=reader.readLine())!=null)
    {
        if (!(line.equals("%")))
        {
            StringTokenizer st = new StringTokenizer(line, "*");
            if (st.countTokens() == 4)          
                list.add(new Person(st.nextToken(), st.nextToken(), Integer.parseInt(st.nextToken()), Integer.parseInt(st.nextToken)));         
            else            
                // whatever you want to do to account for an invalid entry
                  // in your file. (not 4 '*' delimiters on a line). Or you
                  // could write the 'if' clause differently to account for it          
        }
    }
    reader.close();
}

For me below code worked, first sending json string with proper headers

$.ajax({
        type: "POST",
        url : 'save',
        data : JSON.stringify(valObject),
        contentType:"application/json; charset=utf-8",
        dataType:"json",
        success : function(resp){
            console.log(resp);
        },
        error : function(resp){
            console.log(resp);
        }
    });

And then on Spring side -

@RequestMapping(value = "/save", 
                method = RequestMethod.POST,
                consumes="application/json")
public @ResponseBody String  save(@RequestBody ArrayList<KeyValue> keyValList) {
    //Saving call goes here
    return "";
}

Here KeyValue is simple pojo that corresponds to your JSON structure also you can add produces as you wish, I am simply returning string.

My json object is like this -

[{"storedKey":"vc","storedValue":"1","clientId":"1","locationId":"1"},
 {"storedKey":"vr","storedValue":"","clientId":"1","locationId":"1"}]

And many lines may look like this. The html here is sample only.

var div = document.createElement("div");

div.innerHTML =
    '<div class="slideshow-container">\n' +
    '<div class="mySlides fade">\n' +
    '<div class="numbertext">1 / 3</div>\n' +
    '<img src="image1.jpg" style="width:100%">\n' +
    '<div class="text">Caption Text</div>\n' +
    '</div>\n' +

    '<div class="mySlides fade">\n' +
    '<div class="numbertext">2 / 3</div>\n' +
    '<img src="image2.jpg" style="width:100%">\n' +
    '<div class="text">Caption Two</div>\n' +
    '</div>\n' +

    '<div class="mySlides fade">\n' +
    '<div class="numbertext">3 / 3</div>\n' +
    '<img src="image3.jpg" style="width:100%">\n' +
    '<div class="text">Caption Three</div>\n' +
    '</div>\n' +

    '<a class="prev" onclick="plusSlides(-1)">&#10094;</a>\n' +
    '<a class="next" onclick="plusSlides(1)">&#10095;</a>\n' +
    '</div>\n' +
    '<br>\n' +

    '<div style="text-align:center">\n' +
    '<span class="dot" onclick="currentSlide(1)"></span> \n' +
    '<span class="dot" onclick="currentSlide(2)"></span> \n' +
    '<span class="dot" onclick="currentSlide(3)"></span> \n' +
    '</div>\n';

document.body.appendChild(div);

According to MSDN:

By initializing strings with the Empty value instead of null, you can reduce the chances of a NullReferenceException occurring.

Always using IsNullOrEmpty() is good practice nevertheless.

EDIT:

Ok I found why the int.ToString() in LINQtoEF fails, please read this post: Problem with converting int to string in Linq to entities

This works on my side :

        List<string> materialTypes = (from u in result.Users
                                      select u.LastName)
                       .Union(from u in result.Users
                               select SqlFunctions.StringConvert((double) u.UserId)).ToList();

On yours it should be like this:

    IList<String> materialTypes = ((from tom in context.MaterialTypes
                                       where tom.IsActive == true
                                       select tom.Name)
                                       .Union(from tom in context.MaterialTypes
                                       where tom.IsActive == true
                                       select SqlFunctions.StringConvert((double)tom.ID))).ToList();

Thanks, i've learnt something today :)

SimpleDateFormat.format() method takes a Date as a parameter. You can get a Date from a Calendar by calling its getTime() method:

public static String format(GregorianCalendar calendar) {
    SimpleDateFormat fmt = new SimpleDateFormat("dd-MMM-yyyy");
    fmt.setCalendar(calendar);
    String dateFormatted = fmt.format(calendar.getTime());

    return dateFormatted;
}

Also note that the months start at 0, so you probably meant:

int month = Integer.parseInt(splitDate[1]) - 1;

With Kotlin you can do,

// to disable clicks
myButton.isClickable = false 

// to disable button
myButton.isEnabled = false

// to enable clicks
myButton.isClickable = true 

// to enable button
myButton.isEnabled = true

I got the same issue. To solve the issue you need to update your PHP version.
