This one worked, double quotes when $user and $password are outside single quotes. Single quotes when inside a single quote statement.

mysql --user="$user" --password="$password" --database="$user" --execute='DROP DATABASE '$user'; CREATE DATABASE '$user';'

This tool saved me a lot, since I have no Admin permission on my machine and already had nodejs installed. For some reason the configuration on my network does not give me access to other machines just pointing the IP on the browser.

# Using a local.dev vhost
$ browser-sync start --proxy

# Using a local.dev vhost with PORT
$ browser-sync start --proxy local.dev:8001

# Using a localhost address in a sub-dir
$ browser-sync start --proxy localhost:8080/site1

With Spring Boot its not necessary to have any config file like persistence.xml. You can configure with annotations Just configure your DB config for JPA in the

application.properties

spring.datasource.driverClassName=oracle.jdbc.driver.OracleDriver
spring.datasource.url=jdbc:oracle:thin:@DB...
spring.datasource.username=username
spring.datasource.password=pass

spring.jpa.database-platform=org.hibernate.dialect....
spring.jpa.show-sql=true

Then you can use CrudRepository provided by Spring where you have standard CRUD transaction methods. There you can also implement your own SQL's like JPQL.

@Transactional
public interface ObjectRepository extends CrudRepository<Object, Long> {
...
}

And if you still need to use the Entity Manager you can create another class.

public class ObjectRepositoryImpl implements ObjectCustomMethods{

    @PersistenceContext
    private EntityManager em;

}

This should be in your pom.xml

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>1.2.5.RELEASE</version>

If you are using Apache on Windows:

1. Check the name of the Apache service with Win+R+services.msc+Enter (if it's not ApacheX.Y, it should have the name of the software you are using with apache, e.g.: "wampapache64");
2. Start a command prompt as Administrator (using Win+R+cmd+Enter is not enough);
3. Change to Apache's directory, e.g.: cd c:\wamp\bin\apache\apache2.4.9\bin;
4. Check if the config file is OK with: httpd.exe -n "YourServiceName" -t (replace the service name by the one you found on step 1);
5. Make sure that the service is stopped: httpd.exe -k stop -n "YourServiceName"
6. Start it with: httpd.exe -k start -n "YourServiceName"

7. If it starts alright, the problem is no longer there, but if you get:

   AH00072: make_sock: could not bind to address IP:PORT_NUMBER

   AH00451: no listening sockets available, shutting down

   If the port number is not the one you wanted to use, then open the Apache config file (e.g. C:\wamp\bin\apache\apache2.4.9\conf\httpd.conf open with a code editor or wordpad, but not notepad - it does not read new lines properly) and replace the number on the line that starts with Listen with the number of the port you want, save it and repeat step 6. If it is the one you wanted to use, then continue:

8. Check the PID of the process that is using that port with Win+R+resmon+Enter, click on Network tab and then on Ports subtab;
9. Kill it with: taskkill /pid NUMBER /f (/f forces it);
10. Recheck resmon to confirm that the port is free now and repeat step 6.

This ensures that Apache's service was started properly, the configuration on virtual hosts config file as sarul mentioned (e.g.: C:\wamp\bin\apache\apache2.4.9\conf\extra\httpd-vhosts.conf) is necessary if you are setting your files path in there and changing the port as well. If you change it again, remember to restart the service: httpd.exe -k restart -n "YourServiceName".

The lodash 4.6.1 docs have this as an example for object key equality:

_.uniqWith(objects, _.isEqual);

https://lodash.com/docs#uniqWith

If you have jQuery enabled you can use an escapeXml function and not have to worry about escaping arrows or special characters.

<pre>
  ${fn:escapeXml('
    <!-- all your code --> 
  ')};
</pre>

How about IndexOf?

Searches for the specified object and returns the index of the first occurrence within the list

For example

> var boys = new List<string>{"Harry", "Ron", "Neville"};  
> boys.IndexOf("Neville")  
2
> boys[2] == "Neville"
True

Note that it returns -1 if the value doesn't occur in the list

> boys.IndexOf("Hermione")  
-1

Since php4 you can use a string formater:

$num = 5;
$word = 'banana';
$format = 'can you say %d times the word %s';
echo sprintf($format, $num, $word);

Source: sprintf()

We can get a list of object in dict:

def queryset_to_dict(query_result):
   query_columns = query_result[0].keys()
   res = [list(ele) for ele in query_result]
   dict_list = [dict(zip(query_columns, l)) for l in res]
   return dict_list

query_result = db.session.query(LanguageMaster).all()
dictvalue=queryset_to_dict(query_result)

If there is no authentication enabled (username/password) and still unable to connect. Just use localhost and default port. Click Test and Save, if test connection is successful.

Click on the class and press the Alt + Shift + R keys, then you can change it to the required name and the corresponding file name will also be changed.

You can use esentutl to copy (mainly big) files with a progress bar:

esentutl /y "my.file" /d "another.file" /o

the progress bar looks like this:

Following @dennmatt 's answer, I noticed that InternetAddress.lookup may return successful results even if the internet connection is off - I tested it by connecting from my simulator to my home WiFi, and then disconnecting my router's cable. I think the reason is that the router caches the domain-lookup results so it does not have to query the DNS servers on each lookup request.

Anyways, if you use Firestore like me, you can replace the try-SocketException-catch block with an empty transaction and catch TimeoutExceptions:

try {
  await Firestore.instance.runTransaction((Transaction tx) {}).timeout(Duration(seconds: 5));
  hasConnection = true;
} on PlatformException catch(_) { // May be thrown on Airplane mode
  hasConnection = false;
} on TimeoutException catch(_) {
  hasConnection = false;
}

Also, please notice that previousConnection is set before the async intenet-check, so theoretically if checkConnection() is called multiple times in a short time, there could be multiple hasConnection=true in a row or multiple hasConnection=false in a row. I'm not sure if @dennmatt did it on purpose or not, but in our use-case there were no side effects (setState was only called twice with the same value).

* This was edited to allow for children of the target class to trigger the events. See bottom of the answer for details. *

An alternative answer to add an event listener to a class where items are frequently being added and removed. This is inspired by jQuery's on function where you can pass in a selector for a child element that the event is listening on.

var base = document.querySelector('#base'); // the container for the variable content
var selector = '.card'; // any css selector for children

base.addEventListener('click', function(event) {
  // find the closest parent of the event target that
  // matches the selector
  var closest = event.target.closest(selector);
  if (closest && base.contains(closest)) {
    // handle class event
  }
});

Fiddle: https://jsfiddle.net/u6oje7af/94/

This will listen for clicks on children of the base element and if the target of a click has a parent matching the selector, the class event will be handled. You can add and remove elements as you like without having to add more click listeners to the individual elements. This will catch them all even for elements added after this listener was added, just like the jQuery functionality (which I imagine is somewhat similar under the hood).

This depends on the events propagating, so if you stopPropagation on the event somewhere else, this may not work. Also, the closest function has some compatibility issues with IE apparently (what doesn't?).

This could be made into a function if you need to do this type of action listening repeatedly, like

function addChildEventListener(base, eventName, selector, handler) {
  base.addEventListener(eventName, function(event) {
    var closest = event.target.closest(selector);
    if (closest && base.contains(closest)) {
      // passes the event to the handler and sets `this`
      // in the handler as the closest parent matching the
      // selector from the target element of the event
      handler.call(closest, event);
    }
  });
}

=========================================
EDIT: This post originally used the matches function for DOM elements on the event target, but this restricted the targets of events to the direct class only. It has been updated to use the closest function instead, allowing for events on children of the desired class to trigger the events as well. The original matches code can be found at the original fiddle: https://jsfiddle.net/u6oje7af/23/

update() is now deprecated and you should use replace_one(), update_one(), or update_many() instead.

In my case I used update_many() and it solved my issue:

db.your_collection.update_many({}, {"$set": {"new_field": "value"}}, upsert=False, array_filters=None)

From documents

update_many(filter, update, upsert=False, array_filters=None, bypass_document_validation=False, collation=None, session=None)


filter: A query that matches the documents to update.

update: The modifications to apply.

upsert (optional): If True, perform an insert if no documents match the filter.

bypass_document_validation (optional): If True, allows the write to opt-out of document level validation. Default is False.

collation (optional): An instance of Collation. This option is only supported on MongoDB 3.4 and above.

array_filters (optional): A list of filters specifying which array elements an update should apply. Requires MongoDB 3.6+.

session (optional): a ClientSession.

Raw sql query is fastest way I suppose

public void DeleteCustomer(int id)
{
   using (var context = new Context())
   {
      const string query = "DELETE FROM [dbo].[Customers] WHERE [id]={0}";
      var rows = context.Database.ExecuteSqlCommand(query,id);
      // rows >= 1 - count of deleted rows,
      // rows = 0 - nothing to delete.
   }
}

I figured out why the portrait view wasn't totally filling the viewport. At least in my case, it was because the scrollbar was always showing. In addition to the viewport code above, try adding this:

    browser.setScrollBarStyle(WebView.SCROLLBARS_OUTSIDE_OVERLAY);
    browser.setScrollbarFadingEnabled(false);

This causes the scrollbar to not take up layout space, and allows the webpage to fill the viewport.

Hope this helps

The easiest might be:

Array(1, 2, 3) :+ 4

Actually, Array can be implcitly transformed in a WrappedArray

This is not possible with the magic methods, however you can achieve this using DQL (Doctrine Query Language). In your example, assuming you have entity named Orders with Product property, just go ahead and do the following:

$dql_query = $em->createQuery("
    SELECT o FROM AcmeCodeBundle:Orders o
    WHERE 
      o.OrderEmail = '[email protected]' AND
      o.Product LIKE 'My Products%'
");
$orders = $dql_query->getResult();

Should do exactly what you need.

Alternatively, I would suggest turning interactive on in the beginning and at the very last plot, turn it off. All will show up, but they will not disappear as your program will stay around until you close the figures.

import matplotlib.pyplot as plt
from matplotlib import interactive

plt.figure(1)
... code to make figure (1)

interactive(True)
plt.show()

plt.figure(2)
... code to make figure (2)

plt.show()

plt.figure(3)
... code to make figure (3)

interactive(False)
plt.show()

Just add this code to .vimrc (or .gvimrc)

nnoremap <A-j> :m+<CR>==
nnoremap <A-k> :m-2<CR>==
inoremap <A-j> <Esc>:m+<CR>==gi
inoremap <A-k> <Esc>:m-2<CR>==gi
vnoremap <A-j> :m'>+<CR>gv=gv
vnoremap <A-k> :m-2<CR>gv=gv

json_decode($json, true); 
// the second param being true will return associative array. This one is easy.

The ODP.Net provider from oracle uses bind by position as default. To change the behavior to bind by name. Set property BindByName to true. Than you can dismiss the double definition of parameters.

using(OracleCommand cmd = con.CreateCommand()) {
    ...
    cmd.BindByName = true;
    ...
}

I had the same error and could not figure it out with the other answers. I found that we can "Consolidate" NuGet packages.

1. Right click on the solution
2. Click Manage Nuget Packages
3. Consolidate tab and update to the same version.

Best approach will be using map where key will be element and value will be the count of each element. Along with that keep an array of size that will contain the index of most popular element . Populate this array while map construction itself so that we don't have to iterate through map again.

Approach 2:-

If someone want to go with two loop, here is the improvisation from accepted answer where we don't have to start second loop from one every time

public class TestPopularElements {
    public static int getPopularElement(int[] a) {
        int count = 1, tempCount;
        int popular = a[0];
        int temp = 0;
        for (int i = 0; i < (a.length - 1); i++) {
            temp = a[i];
            tempCount = 0;
            for (int j = i+1; j < a.length; j++) {
                if (temp == a[j])
                    tempCount++;
            }
            if (tempCount > count) {
                popular = temp;
                count = tempCount;
            }
        }
        return popular;
    }

    public static void main(String[] args) {
        int a[] = new int[] {1,2,3,4,5,6,2,7,7,7};

        System.out.println("count is " +getPopularElement(a));
    }

}

For Mac Catilina 10.15.5 and later version:

add in your ~/.zshrc file

function parse_git_branch() {
    git branch 2> /dev/null | sed -n -e 's/^\* \(.*\)/[\1]/p'
}

setopt PROMPT_SUBST
export PROMPT='%F{grey}%n%f %F{cyan}%~%f %F{green}$(parse_git_branch)%f %F{normal}$%f '

According to mysql docs: "to rename TEMPORARY tables, RENAME TABLE does not work. Use ALTER TABLE instead."

So this is the most portable method:

ALTER TABLE `old_name` RENAME `new_name`;

use pd.to_numeric()

df["DateColumn"] = pd.to_numeric(df["DateColumn"])

simple and clean

I was in a similar situation and wanted to update urllib3 package. What worked for me was:

pip3 install --upgrade --force-reinstall --ignore-installed urllib3==1.25.3

Go to the download page and download the Windows x86 version with filename jdk-7-windows-i586.exe.

You can use TIMESTAMPDIFF(unit, datetime_expr1, datetime_expr2) function:

SELECT TIMESTAMPDIFF(YEAR, '1970-02-01', CURDATE()) AS age

Demo

What I would do is comment out the Dockerfile below and including the offending line. Then you can run the container and run the docker commands by hand, and look at the logs in the usual way. E.g. if the Dockerfile is

RUN foo
RUN bar
RUN baz

and it's dying at bar I would do

RUN foo
# RUN bar
# RUN baz

Then

$ docker build -t foo .
$ docker run -it foo bash
container# bar
...grep logs...

You can also receive a 406 response when invalid cookies are stored or referenced in the browser - for example, when running a Rails server in Dev mode locally.

If you happened to run two different projects on the same port, the browser might reference a cookie from a different localhost session.

This has happened to me...tripped me up for a minute. Looking in browser > Developer Mode > Network showed it.

Java doesn't allow you to do that. You'll need to refer to one of the classes by its fully qualified name and only import the other one.

If you use large values for the paddings (e.g. greater than 0.5em), you'll start to see the text that overflows the content(-box) area, and that might lead you to think that the height is not exactly x rows (that you set), but it is. To understand what's going on, you might want to check out The box model and box-sizing pages.

Could your issue be linked to this other SO question "checkout problem"?

i.e.: a problem related to:

• an old version of Git
• a curious checkout syntax, which should be: git checkout -b [<new_branch>] [<start_point>], with [<start_point>] referring to the name of a commit at which to start the new branch, and 'origin/remote-name' is not that.
  (whereas git branch does support a start_point being the name of a remote branch)

Note: what the checkout.sh script says is:

  if test '' != "$newbranch$force$merge"
  then
    die "git checkout: updating paths is incompatible with switching branches/forcing$hint"
  fi

It is like the syntax git checkout -b [] [remote_branch_name] was both renaming the branch and resetting the new starting point of the new branch, which is deemed incompatible.

When rebase or push to head/master this error may occurred

remote: GitLab: You are not allowed to access some of the refs!
To git@giturl:main/xyz.git
 ! [remote rejected] master -> master (pre-receive hook declined)
error: failed to push some refs to 'git@giturl:main/xyz.git'

To resolve this issue in git dashboard should remove master branch from "Protected branches"

then you can run this command

git push -f origin master

or

git rebase --onto temp $1 master

This work in both Python 2 and 3:

>>> bytearray(b'ABCD')
bytearray(b'ABCD')

Note string started with b.

To get individual chars:

>>> print("DEC HEX ASC")
... for b in bytearray(b'ABCD'):
...     print(b, hex(b), chr(b))
DEC HEX ASC
65 0x41 A
66 0x42 B
67 0x43 C
68 0x44 D

Hope this helps

That is a binary operator in hibernate you should use

is not null

Have a look at 14.10. Expressions

There are several ways to do it. The subplots method creates the figure along with the subplots that are then stored in the ax array. For example:

import matplotlib.pyplot as plt

x = range(10)
y = range(10)

fig, ax = plt.subplots(nrows=2, ncols=2)

for row in ax:
    for col in row:
        col.plot(x, y)

plt.show()

However, something like this will also work, it's not so "clean" though since you are creating a figure with subplots and then add on top of them:

fig = plt.figure()

plt.subplot(2, 2, 1)
plt.plot(x, y)

plt.subplot(2, 2, 2)
plt.plot(x, y)

plt.subplot(2, 2, 3)
plt.plot(x, y)

plt.subplot(2, 2, 4)
plt.plot(x, y)

plt.show()

Here is how to do this as of Typescript 2.0: (tsd and typings are being deprecated in favor of the following):

$ npm install --save lodash

# This is the new bit here: 
$ npm install --save-dev @types/lodash

Then, in your .ts file:

Either:

import * as _ from "lodash";

Or (as suggested by @Naitik):

import _ from "lodash";

I'm not positive what the difference is. We use and prefer the first syntax. However, some report that the first syntax doesn't work for them, and someone else has commented that the latter syntax is incompatible with lazy loaded webpack modules. YMMV.

Edit on Feb 27th, 2017:

According to @Koert below, import * as _ from "lodash"; is the only working syntax as of Typescript 2.2.1, lodash 4.17.4, and @types/lodash 4.14.53. He says that the other suggested import syntax gives the error "has no default export".

Add the following to the top of your file # coding=utf-8

      if (tokenDetails != null && tokenDetails.Any())
      {
         var tokenNo = tokenDetails.FirstOrDefault().Value;
         client.DefaultRequestHeaders.Add("Authorization", "Bearer " + tokenNo);
         client.PostAsJsonAsync("api/menu", messageDetails)
             .ContinueWith((postTask) => postTask.Result.EnsureSuccessStatusCode());
      }
   }
}

The classes of problem that are well suited for a mapreduce style solution are problems of aggregation. Of extracting data from a dataset. In C#, one could take advantage of LINQ to program in this style.

From the following article: http://codecube.net/2009/02/mapreduce-in-c-using-linq/

the GroupBy method is acting as the map, while the Select method does the job of reducing the intermediate results into the final list of results.

var wordOccurrences = words
                .GroupBy(w => w)
                .Select(intermediate => new
                {
                    Word = intermediate.Key,
                    Frequency = intermediate.Sum(w => 1)
                })
                .Where(w => w.Frequency > 10)

As well as \singlespacing mentioned previously to reduce the height of the table, a useful way to reduce the width of the table is to add \tabcolsep=0.11cm before the \begin{tabular} command and take out all the vertical lines between columns. It's amazing how much space is used up between the columns of text. You could reduce the font size to something smaller than \small but I normally wouldn't use anything smaller than \footnotesize.

Strings are hard work in C.

#include <stdio.h>

int main()
{
   int i;
   char buf[12];

   for (i = 0; i < 100; i++) {
      snprintf(buf, 12, "pre_%d_suff", i); // puts string into buffer
      printf("%s\n", buf); // outputs so you can see it
   }
}

The 12 is enough bytes to store the text "pre_", the text "_suff", a string of up to two characters ("99") and the NULL terminator that goes on the end of C string buffers.

This will tell you how to use snprintf, but I suggest a good C book!

First, the enum methods shouldn't be in all caps. They are methods just like other methods, with the same naming convention.

Second, what you are doing is not the best possible way to set up your enum. Instead of using an array of values for the values, you should use separate variables for each value. You can then implement the constructor like you would any other class.

Here's how you should do it with all the suggestions above:

public enum States {
    ...
    MASSACHUSETTS("Massachusetts",  "MA",   true),
    MICHIGAN     ("Michigan",       "MI",   false),
    ...; // all 50 of those

    private final String full;
    private final String abbr;
    private final boolean originalColony;

    private States(String full, String abbr, boolean originalColony) {
        this.full = full;
        this.abbr = abbr;
        this.originalColony = originalColony;
    }

    public String getFullName() {
        return full;
    }

    public String getAbbreviatedName() {
        return abbr;
    }

    public boolean isOriginalColony(){
        return originalColony;
    }
}

To change the color of button programmatically

Here it is :

Button b1;
//colorAccent is the resource made in the color.xml file , you can change it.
b1.setBackgroundResource(R.color.colorAccent);  

There is no direct string compare function in SQL Server

CASE
  WHEN str1 = str2 THEN 0
  WHEN str1 < str2 THEN -1
  WHEN str1 > str2 THEN 1
  ELSE NULL --one of the strings is NULL so won't compare (added on edit)
END

Notes

• you can wraps this via a UDF using CREATE FUNCTION etc
• you may need NULL handling (in my code above, any NULL will report 1)
• str1 and str2 will be column names or @variables

Use explicit injection. No other approach will allow you for instance to run tests in parallel in the same JVM.

Patterns that use anything classloader wide like static log binder or messing with environmental thinks like logback.XML are bust when it comes to testing.

Consider the parallelized tests I mention , or consider the case where you want to intercept logging of component A whose construction is hidden behind api B. This latter case is easy to deal with if you are using a dependency injected loggerfactory from the top, but not if you inject Logger as there no seam in this assembly at ILoggerFactory.getLogger.

And its not all about unit testing either. Sometimes we want integration tests to emit logging. Sometimes we don't. Someone's we want some of the integration testing logging to be selectively suppressed, eg for expected errors that would otherwise clutter the CI console and confuse. All easy if you inject ILoggerFactory from the top of your mainline (or whatever di framework you might use)

So...

Either inject a reporter as suggested or adopt a pattern of injecting the ILoggerFactory. By explicit ILoggerFactory injection rather than Logger you can support many access/intercept patterns and parallelization.

You could simply use echo on and you will see that goto :eof or even exit /b doesn't work as expected.

The code inside of the loop isn't executed anymore, but the loop is expanded for all numbers to the end.
That's why it's so slow.

The only way to exit a FOR /L loop seems to be the variant of exit like the exsample of Wimmel, but this isn't very fast nor useful to access any results from the loop.

This shows 10 expansions, but none of them will be executed

echo on
for /l %%n in (1,1,10) do (
  goto :eof
  echo %%n
)

Try to use the fleqn document class option.

\documentclass[fleqn]{article}

(See also http://en.wikibooks.org/wiki/LaTeX/Basics for a list of other options.)

you can used:

$("#d").val(null).trigger("change"); 

It's very simple and work right! If use with reset button:

$('#btnReset').click(function() {
    $("#d").val(null).trigger("change"); 
});

Something that is frustrating is that when you are developing in Eclipse MyClass.class.getProtectionDomain().getCodeSource().getLocation() returns the /bin directory which is great, but when you compile it to a jar, the path includes the /myjarname.jar part which gives you illegal file names.

To have the code work both in the ide and once it is compiled to a jar, I use the following piece of code:

URL applicationRootPathURL = getClass().getProtectionDomain().getCodeSource().getLocation();
File applicationRootPath = new File(applicationRootPathURL.getPath());
File myFile;
if(applicationRootPath.isDirectory()){
    myFile = new File(applicationRootPath, "filename");
}
else{
    myFile = new File(applicationRootPath.getParentFile(), "filename");
}

You need to add http_proxy and https_proxy environment variables as described here.

Removing ./ from source path should resolve your issue:

 COPY test.json /home/test.json
 COPY test.py /home/test.py

In general, in C++ functions have to be declared before you call them. So sometime before the definition of getSkewNormal(), the compiler needs to see the declaration:

double integrate (double start, double stop, int numSteps, Evaluatable evalObj);

Mostly what people do is put all the declarations (only) in the header file, and put the actual code -- the definitions of the functions and methods -- into a separate source (*.cc or *.cpp) file. This neatly solves the problem of needing all the functions to be declared.

try if( $(response).filter('#result').length ) // do something

Here you can find some public REST services for encryption and security related things: http://security.jelastic.servint.net

You can either use the eval function as in some other answers. (Don't forget the extra braces.) You will know why when you dig deeper), or simply use the jQuery function parseJSON:

var response = '{"result":true , "count":1}'; 
var parsedJSON = $.parseJSON(response);

OR

You can use this below code.

var response = '{"result":true , "count":1}';
var jsonObject = JSON.parse(response);

And you can access the fields using jsonObject.result and jsonObject.count.

Update:

If your output is undefined then you need to follow THIS answer. Maybe your json string has an array format. You need to access the json object properties like this

var response = '[{"result":true , "count":1}]'; // <~ Array with [] tag
var jsonObject = JSON.parse(response);
console.log(jsonObject[0].result); //Output true
console.log(jsonObject[0].count); //Output 1

in my case i have saved a json file with a space like this

google-services .json

and the right one is

google-services.json

and also take care you do not put (_) instead of (-)

may help some one.

As others have answered, scatter() or plot() will generate the plot you want. I suggest two refinements to answers that are already here:

1. Use numpy to create the x-coordinate list and y-coordinate list. Working with large data sets is faster in numpy than using the iteration in Python suggested in other answers.

2. Use pyplot to apply the logarithmic scale rather than operating directly on the data, unless you actually want to have the logs.

   import matplotlib.pyplot as plt
   import numpy as np
   
   data = [(2, 10), (3, 100), (4, 1000), (5, 100000)]
   data_in_array = np.array(data)
   '''
   That looks like array([[     2,     10],
                          [     3,    100],
                          [     4,   1000],
                          [     5, 100000]])
   '''
   
   transposed = data_in_array.T
   '''
   That looks like array([[     2,      3,      4,      5],
                          [    10,    100,   1000, 100000]])
   '''    
   
   x, y = transposed 
   
   # Here is the OO method
   # You could also the state-based methods of pyplot
   fig, ax = plt.subplots(1,1) # gets a handle for the AxesSubplot object
   ax.plot(x, y, 'ro')
   ax.plot(x, y, 'b-')
   ax.set_yscale('log')
   fig.show()
   

I've also used ax.set_xlim(1, 6) and ax.set_ylim(.1, 1e6) to make it pretty.

I've used the object-oriented interface to matplotlib. Because it offers greater flexibility and explicit clarity by using names of the objects created, the OO interface is preferred over the interactive state-based interface.

You could use querySelector() with attribute selector '[attribute="value"]', then affect css rule using .style, as you can see in the example below:

document.querySelector('a[aria-expanded="true"]').style.backgroundColor = "#42DCA3";

<ul><li class="active">_x000D_
  <a href="#3a" class="btn btn-default btn-lg" data-toggle="tab" aria-expanded="true"> <span class="network-name">Google+ with aria expanded true</span></a>_x000D_
  </li>_x000D_
  <li>_x000D_
    <a href="#3a" class="btn btn-default btn-lg" data-toggle="tab" aria-expanded="false"> <span class="network-name">Google+ with aria expanded false</span></a>_x000D_
  </li>_x000D_
</ul>

jQuery solution :

If you want to use a jQuery solution you could simply use css() method :

$('a[aria-expanded="true"]').css('background-color','#42DCA3');

Hope this helps.

you can used this way: create extension

extension UIView {

    func addTapGesture(action : @escaping ()->Void ){
        let tap = MyTapGestureRecognizer(target: self , action: #selector(self.handleTap(_:)))
        tap.action = action
        tap.numberOfTapsRequired = 1

        self.addGestureRecognizer(tap)
        self.isUserInteractionEnabled = true

    }
    @objc func handleTap(_ sender: MyTapGestureRecognizer) {
        sender.action!()
    }
}

class MyTapGestureRecognizer: UITapGestureRecognizer {
    var action : (()->Void)? = nil
}

and use this way:

@IBOutlet weak var testView: UIView!
testView.addTapGesture{
   // ...
}

i have write the answer here How to add/use libraries in Python (3.5.1) but no problem will rewrite it again

if u have or you can create a file requirements.txt which contains the libraries that you want to install for ex:

numpy==1.14.2
Pillow==5.1.0

You gonna situate in your folder which contains that requirements.txt in my case the path to my project is

C:\Users\LE\Desktop\Projet2_Sig_Exo3\exo 3\k-means

now just type

python -m pip install -r ./requirements.txt

and all the libararies that you want gonna install

C:\Users\LE\Desktop\Projet2_Sig_Exo3\exo 3\k-means>python -m pip install -r ./requirements.txt

Just one more alternative using URL

var theUrl = new URL(window.location.href);
theUrl.search = ""; //Remove any params
theUrl //as URL object
theUrl.href //as a string

I started with johncarls solution, but needed to adjust it to get exactly what I needed. Mainly, I needed it to rotate clockwise when the angle increased. I also needed 0 degrees to point NORTH. His solution got me close, but I decided to post my solution as well in case it helps anyone else.

I've added some additional comments to help explain my understanding of the function in case you need to make simple modifications.

/**
 * Calculates the angle from centerPt to targetPt in degrees.
 * The return should range from [0,360), rotating CLOCKWISE, 
 * 0 and 360 degrees represents NORTH,
 * 90 degrees represents EAST, etc...
 *
 * Assumes all points are in the same coordinate space.  If they are not, 
 * you will need to call SwingUtilities.convertPointToScreen or equivalent 
 * on all arguments before passing them  to this function.
 *
 * @param centerPt   Point we are rotating around.
 * @param targetPt   Point we want to calcuate the angle to.  
 * @return angle in degrees.  This is the angle from centerPt to targetPt.
 */
public static double calcRotationAngleInDegrees(Point centerPt, Point targetPt)
{
    // calculate the angle theta from the deltaY and deltaX values
    // (atan2 returns radians values from [-PI,PI])
    // 0 currently points EAST.  
    // NOTE: By preserving Y and X param order to atan2,  we are expecting 
    // a CLOCKWISE angle direction.  
    double theta = Math.atan2(targetPt.y - centerPt.y, targetPt.x - centerPt.x);

    // rotate the theta angle clockwise by 90 degrees 
    // (this makes 0 point NORTH)
    // NOTE: adding to an angle rotates it clockwise.  
    // subtracting would rotate it counter-clockwise
    theta += Math.PI/2.0;

    // convert from radians to degrees
    // this will give you an angle from [0->270],[-180,0]
    double angle = Math.toDegrees(theta);

    // convert to positive range [0-360)
    // since we want to prevent negative angles, adjust them now.
    // we can assume that atan2 will not return a negative value
    // greater than one partial rotation
    if (angle < 0) {
        angle += 360;
    }

    return angle;
}

There's no mystery here, the linker is telling you that you haven't defined the missing symbols, and you haven't.

Similarity::Similarity() or Similarity::~Similarity() are just missing and you have defined the others incorrectly,

void Similarity::readData(Scanner& inStream){
}

not

void readData(Scanner& inStream){
}

etc. etc.

The second one is a function called readData, only the first is the readData method of the Similarity class.

To be clear about this, in Similarity.h

void readData(Scanner& inStream);

but in Similarity.cpp

void Similarity::readData(Scanner& inStream){
}

It was used as a pattern to store in memory as a series of hex bytes (0xde, 0xad, 0xbe, 0xef). You could see if memory was corrupted because of hardware failure, buffer overruns, etc.

it is working in my google chrome browser version 11.0.696.60

I created a simple page with no other items just basic tags and no separate CSS file and got an image

this is what i setup:

<div id="placeholder" style="width: 60px; height: 60px; border: 1px solid black; background-image: url('http://www.mypicx.com/uploadimg/1312875436_05012011_2.png')"></div>

I put an id just in case there was a hidden id tag and it works

Wouldn't you just change:

numero = stmt.executeUpdate(query);

to:

numero = stmt.executeUpdate(query, Statement.RETURN_GENERATED_KEYS);

Take a look at the documentation for the JDBC Statement interface.

Update: Apparently there is a lot of confusion about this answer, but my guess is that the people that are confused are not reading it in the context of the question that was asked. If you take the code that the OP provided in his question and replace the single line (line 6) that I am suggesting, everything will work. The numero variable is completely irrelevant and its value is never read after it is set.

For reference, you can also utilize initWithDictionary to init the NSMutableDictionary with a literal one:

    @"volup": @0,

I had the same issue it was due to that I had the bootstrap class "hidden-lg" on the table which caused it to stupidly become display: block !important;

I wonder how Bootstrap never considered to just instead do this:

@media (min-width: 1200px) {
    .hidden-lg {
         display: none;
    }
}

And then just leave the element whatever display it had before for other screensizes.. Perhaps it is too advanced for them to figure out..

Anyway so:

table {
    display: table; /* check so these really applies */
    width: 100%;
}

should work

            return dtExcelTable;

        catch (Exception e)

I just read in the MySQL documentation that SHOW FULL PROCESSLIST by default only lists the threads from your current user connection.

Quote from the MySQL SHOW FULL PROCESSLIST documentation:

If you have the PROCESS privilege, you can see all threads.

So you can enable the Process_priv column in your mysql.user table. Remember to execute FLUSH PRIVILEGES afterwards :)

DISCLAMER: Following code creates different threads for each function.

This might be useful for some of the cases as it is simpler to use. But know that it is not async but gives illusion of async using multiple threads, even though decorator suggests that.

To make any function non blocking, simply copy the decorator and decorate any function with a callback function as parameter. The callback function will receive the data returned from the function.

import asyncio
import requests


def run_async(callback):
    def inner(func):
        def wrapper(*args, **kwargs):
            def __exec():
                out = func(*args, **kwargs)
                callback(out)
                return out

            return asyncio.get_event_loop().run_in_executor(None, __exec)

        return wrapper

    return inner


def _callback(*args):
    print(args)


# Must provide a callback function, callback func will be executed after the func completes execution !!
@run_async(_callback)
def get(url):
    return requests.get(url)


get("https://google.com")
print("Non blocking code ran !!")

actions in Vuex are asynchronous. The only way to let the calling function (initiator of action) to know that an action is complete - is by returning a Promise and resolving it later.

Here is an example: myAction returns a Promise, makes a http call and resolves or rejects the Promise later - all asynchronously

actions: {
    myAction(context, data) {
        return new Promise((resolve, reject) => {
            // Do something here... lets say, a http call using vue-resource
            this.$http("/api/something").then(response => {
                // http success, call the mutator and change something in state
                resolve(response);  // Let the calling function know that http is done. You may send some data back
            }, error => {
                // http failed, let the calling function know that action did not work out
                reject(error);
            })
        })
    }
}

Now, when your Vue component initiates myAction, it will get this Promise object and can know whether it succeeded or not. Here is some sample code for the Vue component:

export default {
    mounted: function() {
        // This component just got created. Lets fetch some data here using an action
        this.$store.dispatch("myAction").then(response => {
            console.log("Got some data, now lets show something in this component")
        }, error => {
            console.error("Got nothing from server. Prompt user to check internet connection and try again")
        })
    }
}

As you can see above, it is highly beneficial for actions to return a Promise. Otherwise there is no way for the action initiator to know what is happening and when things are stable enough to show something on the user interface.

And a last note regarding mutators - as you rightly pointed out, they are synchronous. They change stuff in the state, and are usually called from actions. There is no need to mix Promises with mutators, as the actions handle that part.

Edit: My views on the Vuex cycle of uni-directional data flow:

If you access data like this.$store.state["your data key"] in your components, then the data flow is uni-directional.

The promise from action is only to let the component know that action is complete.

The component may either take data from promise resolve function in the above example (not uni-directional, therefore not recommended), or directly from $store.state["your data key"] which is unidirectional and follows the vuex data lifecycle.

The above paragraph assumes your mutator uses Vue.set(state, "your data key", http_data), once the http call is completed in your action.

i find that this works for me

db.getCollection('collectionName').findOne({"fieldName" : {$ne: null}})

First, we need GOPATH

The $GOPATH is a folder (or set of folders) specified by its environment variable. We must notice that this is not the $GOROOT directory where Go is installed.

export GOPATH=$HOME/gocode
export PATH=$PATH:$GOPATH/bin

We used ~/gocode path in our computer to store the source of our application and its dependencies. The GOPATH directory will also store the binaries of their packages.

Then check Go env

You system must have $GOPATH and $GOROOT, below is my Env:

GOARCH="amd64"
GOBIN=""
GOCHAR="6"
GOEXE=""
GOHOSTARCH="amd64"
GOHOSTOS="linux"
GOOS="linux"
GOPATH="/home/elpsstu/gocode"
GORACE=""
GOROOT="/home/pravin/go"
GOTOOLDIR="/home/pravin/go/pkg/tool/linux_amd64"
CC="gcc"
GOGCCFLAGS="-fPIC -m64 -pthread -fmessage-length=0"
CXX="g++"
CGO_ENABLED="1"

Now, you run download go package:

go get [-d] [-f] [-fix] [-t] [-u] [build flags] [packages]

Get downloads and installs the packages named by the import paths, along with their dependencies. For more details you can look here.

A Runnable is basically a type of class (Runnable is an Interface) that can be put into a thread, describing what the thread is supposed to do.

The Runnable Interface requires of the class to implement the method run() like so:

public class MyRunnableTask implements Runnable {
     public void run() {
         // do stuff here
     }
}

And then use it like this:

Thread t = new Thread(new MyRunnableTask());
t.start();

If you did not have the Runnable interface, the Thread class, which is responsible to execute your stuff in the other thread, would not have the promise to find a run() method in your class, so you could get errors. That is why you need to implement the interface.

Advanced: Anonymous Type

Note that you do not need to define a class as usual, you can do all of that inline:

Thread t = new Thread(new Runnable() {
    public void run() {
        // stuff here
    }
});
t.start();

This is similar to the above, only you don't create another named class.

Typically one uses an abstract class to provide some incomplete functionality that will be fleshed out by concrete subclasses. It may provide methods that are used by its subclasses; it may also represent an intermediate node in the class hierarchy, to represent a common grouping of concrete subclasses, distinguishing them in some way from other subclasses of its superclass. Since an interface can't derive from a class, this is another situation where a class (abstract or otherwise) would be necessary, versus an interface.

A good rule of thumb is that only leaf nodes of a class hierarchy should ever be instantiated. Making non-leaf nodes abstract is an easy way of ensuring that.

If your databaseName value is correct, then use this: DriverManger.getconnection("jdbc:sqlserver://ServerIp:1433;user=myuser;password=mypassword;databaseName=databaseName;")

I'm surprised this method hasn't been mentioned: "Some string".split(' ').shift()

To answer the question directly:

let firstWords = []
let str = "Hello m|sss sss|mmm ss";
const codeLines = str.split("|");

for (var i = 0; i < codeLines.length; i++) {
  const first = codeLines[i].split(' ').shift()
  firstWords.push(first)
}

I'm writing logs to the files, which are generate on daily basis (per day one log file is getting generated). This approach is working fine for me :

var (
    serverLogger *log.Logger
)

func init() {
    // set location of log file
    date := time.Now().Format("2006-01-02")
    var logpath = os.Getenv(constant.XDirectoryPath) + constant.LogFilePath + date + constant.LogFileExtension
    os.MkdirAll(os.Getenv(constant.XDirectoryPath)+constant.LogFilePath, os.ModePerm)
    flag.Parse()
    var file, err1 = os.OpenFile(logpath, os.O_RDWR|os.O_CREATE|os.O_APPEND, 0666)

    if err1 != nil {
        panic(err1)
    }
    mw := io.MultiWriter(os.Stdout, file)
    serverLogger = log.New(mw, constant.Empty, log.LstdFlags)
    serverLogger.Println("LogFile : " + logpath)
}

// LogServer logs to server's log file
func LogServer(logLevel enum.LogLevel, message string) {
    _, file, no, ok := runtime.Caller(1)
    logLineData := "logger_server.go"
    if ok {
        file = shortenFilePath(file)
        logLineData = fmt.Sprintf(file + constant.ColonWithSpace + strconv.Itoa(no) + constant.HyphenWithSpace)
    }
    serverLogger.Println(logLineData + logLevel.String() + constant.HyphenWithSpace + message)
}

// ShortenFilePath Shortens file path to a/b/c/d.go tp d.go
func shortenFilePath(file string) string {
    short := file
    for i := len(file) - 1; i > 0; i-- {
        if file[i] == constant.ForwardSlash {
            short = file[i+1:]
            break
        }
    }
    file = short
    return file
}

"shortenFilePath()" method used to get the name of the file from full path of file. and "LogServer()" method is used to create a formatted log statement (contains : filename, line number, log level, error statement etc...)

In your custom adapter inside getView method :

button.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        // Do things Here 
    }
});

Now which drive letter did that removable device get?

Two ways to locate e.g. a USB-disk in git Bash:

    $ cat /proc/partitions
    major minor  #blocks  name   win-mounts

        8     0 500107608 sda
        8     1   1048576 sda1
        8     2    131072 sda2
        8     3 496305152 sda3   C:\

        8    80   3952639 sdf
        8    81   3950592 sdf1   E:\

    $ mount
    C:/Program Files/Git on / type ntfs (binary,noacl,auto)
    C:/Program Files/Git/usr/bin on /bin type ntfs (binary,noacl,auto)
    C:/Users/se2982/AppData/Local/Temp on /tmp type ntfs (binary,noacl,posix=0,usertemp)
    C: on /c type ntfs (binary,noacl,posix=0,user,noumount,auto)
    E: on /e type vfat (binary,noacl,posix=0,user,noumount,auto)
    G: on /g type ntfs (binary,noacl,posix=0,user,noumount,auto)
    H: on /h type ntfs (binary,noacl,posix=0,user,noumount,auto)

... so; likely drive letter in this example => /e (or E:\ if you must), when knowing that C, G, and H are other things (in Windows).

Assuming that the length is same for each array in the second dimension, you can use

public class B {    
 public static void main(String [] main){
    int [] [] nir= new int [2] [3];
    System.out.println(nir[0].length);
 }
}

Functionally, you should be able to use

SELECT column_name
  FROM table_name
 WHERE TRIM(column_name) IS NULL

The problem there is that an index on COLUMN_NAME would not be used. You would need to have a function-based index on TRIM(column_name) if that is a selective condition.

While the solution of moving the contact_email to parameters.yml is easy, as proposed in other answers, that can easily clutter your parameters file if you deal with many bundles or if you deal with nested blocks of configuration.

• First, I'll answer strictly the question.
• Later, I'll give an approach for getting those configs from services without ever passing via a common space as parameters.

FIRST APPROACH: Separated config block, getting it as a parameter

With an extension (more on extensions here) you can keep this easily "separated" into different blocks in the config.yml and then inject that as a parameter gettable from the controller.

Inside your Extension class inside the DependencyInjection directory write this:

class MyNiceProjectExtension extends Extension
{
    public function load( array $configs, ContainerBuilder $container )
    {
        // The next 2 lines are pretty common to all Extension templates.
        $configuration = new Configuration();
        $processedConfig = $this->processConfiguration( $configuration, $configs );

        // This is the KEY TO YOUR ANSWER
        $container->setParameter( 'my_nice_project.contact_email', $processedConfig[ 'contact_email' ] );

        // Other stuff like loading services.yml
    }

Then in your config.yml, config_dev.yml and so you can set

my_nice_project:
    contact_email: [email protected]

To be able to process that config.yml inside your MyNiceBundleExtension you'll also need a Configuration class in the same namespace:

class Configuration implements ConfigurationInterface
{
    public function getConfigTreeBuilder()
    {
        $treeBuilder = new TreeBuilder();
        $rootNode = $treeBuilder->root( 'my_nice_project' );

        $rootNode->children()->scalarNode( 'contact_email' )->end();

        return $treeBuilder;
    }
}

Then you can get the config from your controller, as you desired in your original question, but keeping the parameters.yml clean, and setting it in the config.yml in separated sections:

$recipient = $this->container->getParameter( 'my_nice_project.contact_email' );

SECOND APPROACH: Separated config block, injecting the config into a service

For readers looking for something similar but for getting the config from a service, there is even a nicer way that never clutters the "paramaters" common space and does even not need the container to be passed to the service (passing the whole container is practice to avoid).

This trick above still "injects" into the parameters space your config.

Nevertheless, after loading your definition of the service, you could add a method-call like for example setConfig() that injects that block only to the service.

For example, in the Extension class:

class MyNiceProjectExtension extends Extension
{
    public function load( array $configs, ContainerBuilder $container )
    {
        $configuration = new Configuration();
        $processedConfig = $this->processConfiguration( $configuration, $configs );

        // Do not add a paramater now, just continue reading the services.
        $loader = new YamlFileLoader( $container, new FileLocator( __DIR__ . '/../Resources/config' ) );
        $loader->load( 'services.yml' );

        // Once the services definition are read, get your service and add a method call to setConfig()
        $sillyServiceDefintion = $container->getDefinition( 'my.niceproject.sillymanager' );
        $sillyServiceDefintion->addMethodCall( 'setConfig', array( $processedConfig[ 'contact_email' ] ) );
    }
}

Then in your services.yml you define your service as usual, without any absolute change:

services:
    my.niceproject.sillymanager:
        class: My\NiceProjectBundle\Model\SillyManager
        arguments: []

And then in your SillyManager class, just add the method:

class SillyManager
{
    private $contact_email;

    public function setConfig( $newConfigContactEmail )
    {
        $this->contact_email = $newConfigContactEmail;
    }
}

Note that this also works for arrays instead of scalar values! Imagine that you configure a rabbit queue and need host, user and password:

my_nice_project:
    amqp:
        host: 192.168.33.55
        user: guest
        password: guest

Of course you need to change your Tree, but then you can do:

$sillyServiceDefintion->addMethodCall( 'setConfig', array( $processedConfig[ 'amqp' ] ) );

and then in the service do:

class SillyManager
{
    private $host;
    private $user;
    private $password;

    public function setConfig( $config )
    {
        $this->host = $config[ 'host' ];
        $this->user = $config[ 'user' ];
        $this->password = $config[ 'password' ];
    }
}

Hope this helps!

I know that in SQL 2012 (may work in other versions) you can do the following:

1. Right click on the database name in the Object Explorer.
2. Select Reports > Standard Reports > Disk Usage by Top Tables.

That will give you a list of the top 1000 tables and then you can order it by data size etc.

maybe you can try using

SELECT user_name
FROM user_master
WHERE upper(user_name) LIKE '%ME%'

How to include the jars of your project into your runnable jar:

I'm using Eclipse Version: 3.7.2 running on Ubuntu 12.10. I'll also show you how to make the build.xml so you can do the ant jar from command line and create your jar with other imported jars extracted into it.

Basically you ask Eclipse to construct the build.xml that imports your libraries into your jar for you.

1. Fire up Eclipse and make a new Java project, make a new package 'mypackage', add your main class: Runner Put this code in there.

   

2. Now include the mysql-connector-java-5.1.28-bin.jar from Oracle which enables us to write Java to connect to the MySQL database. Do this by right clicking the project -> properties -> java build path -> Add External Jar -> pick mysql-connector-java-5.1.28-bin.jar.

3. Run the program within eclipse, it should run, and tell you that the username/password is invalid which means Eclipse is properly configured with the jar.

4. In Eclipse go to File -> Export -> Java -> Runnable Jar File. You will see this dialog:

   

   Make sure to set up the 'save as ant script' checkbox. That is what makes it so you can use the commandline to do an ant jar later.

5. Then go to the terminal and look at the ant script:

   

So you see, I ran the jar and it didn't error out because it found the included mysql-connector-java-5.1.28-bin.jar embedded inside Hello.jar.

Look inside Hello.jar: vi Hello.jar and you will see many references to com/mysql/jdbc/stuff.class

To do ant jar on the commandline to do all this automatically: Rename buildant.xml to build.xml, and change the target name from create_run_jar to jar.

Then, from within MyProject you type ant jar and boom. You've got your jar inside MyProject. And you can invoke it using java -jar Hello.jar and it all works.

Have you considered applying ON DELETE CASCADE where relevant?

You can do it via the constructor of your class:

public class foo {
  public foo(){
    Bar = "bar";
  }
  public string Bar {get;set;}
}

If you've got another constructor (ie, one that takes paramters) or a bunch of constructors you can always have this (called constructor chaining):

public class foo {
  private foo(){
    Bar = "bar";
    Baz = "baz";
  }
  public foo(int something) : this(){
    //do specialized initialization here
    Baz = string.Format("{0}Baz", something);
  }
  public string Bar {get; set;}
  public string Baz {get; set;}
}

If you always chain a call to the default constructor you can have all default property initialization set there. When chaining, the chained constructor will be called before the calling constructor so that your more specialized constructors will be able to set different defaults as applicable.

Now there is an official way to add "PlantUML integration" plugin to your JetBrains product.

Installation steps please refer: https://stackoverflow.com/a/53387418/5320704

use this

if (userProfile.AccountType == AccountType.Retailer)
{
     ...
}

If you want to get int from your AccountType enum and compare it (don't know why) do this:

if((int)userProfile.AccountType == 1)
{ 
     ...
}

Objet reference not set to an instance of an object exception is because your userProfile is null and you are getting property of null. Check in debug why it's not set.

EDIT (thanks to @Rik and @KonradMorawski) :

Maybe you can do some check before:

if(userProfile!=null)
{
}

or

if(userProfile==null)
{
   throw new ArgumentNullException(nameof(userProfile)); // or any other exception
}

simple load xml file ..

$xml = @simplexml_load_string($retValuet);

$status = (string)$xml->Status; 
$operator_trans_id = (string)$xml->OPID;
$trns_id = (string)$xml->TID;

?>

The reason must be somewhere else. Using only Spring Boot 1.2.2 out of the box with no configuration, it Just Works. Have a look at this repo - can you get it to break?

https://github.com/konrad-garus/so-yaml

Are you sure the YAML file looks exactly the way you pasted? No extra whitespace, characters, special characters, mis-indentation or something of that sort? Is it possible you have another file elsewhere in the search path that is used instead of the one you're expecting?

In case the Jenkins is triggering a build by restricting it to run on a slave or any other server (you may find it in the below setting under 'configure')

then the Path to Git executable should be set as per the 'slave_server_hostname' or any other server where the git commands are executed.

What it does

Maven is a "build management tool", it is for defining how your .java files get compiled to .class, packaged into .jar (or .war or .ear) files, (pre/post)processed with tools, managing your CLASSPATH, and all others sorts of tasks that are required to build your project. It is similar to Apache Ant or Gradle or Makefiles in C/C++, but it attempts to be completely self-contained in it that you shouldn't need any additional tools or scripts by incorporating other common tasks like downloading & installing necessary libraries etc.

It is also designed around the "build portability" theme, so that you don't get issues as having the same code with the same buildscript working on one computer but not on another one (this is a known issue, we have VMs of Windows 98 machines since we couldn't get some of our Delphi applications compiling anywhere else). Because of this, it is also the best way to work on a project between people who use different IDEs since IDE-generated Ant scripts are hard to import into other IDEs, but all IDEs nowadays understand and support Maven (IntelliJ, Eclipse, and NetBeans). Even if you don't end up liking Maven, it ends up being the point of reference for all other modern builds tools.

Why you should use it

There are three things about Maven that are very nice.

1. Maven will (after you declare which ones you are using) download all the libraries that you use and the libraries that they use for you automatically. This is very nice, and makes dealing with lots of libraries ridiculously easy. This lets you avoid "dependency hell". It is similar to Apache Ant's Ivy.

2. It uses "Convention over Configuration" so that by default you don't need to define the tasks you want to do. You don't need to write a "compile", "test", "package", or "clean" step like you would have to do in Ant or a Makefile. Just put the files in the places in which Maven expects them and it should work off of the bat.

3. Maven also has lots of nice plug-ins that you can install that will handle many routine tasks from generating Java classes from an XSD schema using JAXB to measuring test coverage with Cobertura. Just add them to your pom.xml and they will integrate with everything else you want to do.

The initial learning curve is steep, but (nearly) every professional Java developer uses Maven or wishes they did. You should use Maven on every project although don't be surprised if it takes you a while to get used to it and that sometimes you wish you could just do things manually, since learning something new sometimes hurts. However, once you truly get used to Maven you will find that build management takes almost no time at all.

How to Start

The best place to start is "Maven in 5 Minutes". It will get you start with a project ready for you to code in with all the necessary files and folders set-up (yes, I recommend using the quickstart archetype, at least at first).

After you get started you'll want a better understanding over how the tool is intended to be used. For that "Better Builds with Maven" is the most thorough place to understand the guts of how it works, however, "Maven: The Complete Reference" is more up-to-date. Read the first one for understanding, but then use the second one for reference.

For Windows/WSL/Cygwin etc users:

Make sure that your line endings are standard Unix line feeds, i.e. \n (LF) only.

Using Windows line endings \r\n (CRLF) line endings will break the command line break.

This is because having \ at the end of a line with Windows line ending translates to \ \r \n.
As Mark correctly explains above:

The line-continuation will fail if you have whitespace after the backslash and before the newline.

This includes not just space () or tabs (\t) but also the carriage return (\r).

here is my approach:

You can use it in other event.

var id;_x000D_
$("#panel :input").each(function(e){ _x000D_
  id = this.id;_x000D_
  // show id _x000D_
  console.log("#"+id);_x000D_
  // show input value _x000D_
  console.log(this.value);_x000D_
  // disable input if you want_x000D_
  //$("#"+id).prop('disabled', true);_x000D_
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>_x000D_
<div id="panel">_x000D_
  <table>_x000D_

       <td><input id="Search_NazovProjektu" type="text" value="Naz Val" /></td>_x000D_

Angular 2 and Angular 4 

In a ngFor loop it must be look like this:

<div class="column" *ngFor="let u of events ">
                <div class="thumb">
                    <img src="assets/uploads/{{u.image}}">
                    <h4>{{u.name}}</h4>
                </div>
                <div class="info">
                    <img src="assets/uploads/{{u.image}}">
                    <h4>{{u.name}}</h4>
                    <p>{{u.text}}</p>
                </div>
            </div>

In the first example, you are reassigning the variable a, while in the second one you are modifying the data in-place, using the += operator.

See the section about 7.2.1. Augmented assignment statements :

An augmented assignment expression like x += 1 can be rewritten as x = x + 1 to achieve a similar, but not exactly equal effect. In the augmented version, x is only evaluated once. Also, when possible, the actual operation is performed in-place, meaning that rather than creating a new object and assigning that to the target, the old object is modified instead.

+= operator calls __iadd__. This function makes the change in-place, and only after its execution, the result is set back to the object you are "applying" the += on.

__add__ on the other hand takes the parameters and returns their sum (without modifying them).

Use setInterval instead of setTimeout. Though in this case either will be fine but setTimeout inherently triggers only once setInterval continues indefinitely.

<script language="javascript">
setInterval(function(){
   window.location.reload(1);
}, 30000);
</script>

You're looking for a non-greedy (or lazy) match. To get a non-greedy match in regular expressions you need to use the modifier ? after the quantifier. For example you can change .* to .*?.

By default grep doesn't support non-greedy modifiers, but you can use grep -P to use the Perl syntax.

Select the text of all items under produce:

//produce/item/text()

Select all the manager nodes in all departments:

//department/*

Using %lf will help you in solving this problem.

Use :

scanf("%lf",&doub)

try like below it will work...

<html>
<head>
<script>
function displayResult(element)
{
document.getElementById(element).value = 'hi';
}
</script>
</head>
<body>

<textarea id="myTextarea" cols="20">
BYE
</textarea>
<br>

<button type="button" onclick="displayResult('myTextarea')">Change</button>

</body>
</html>

There are two different types of quotation marks in MySQL. You need to use ` for column names and ' for strings. Since you have used ' for the filename column the query parser got confused. Either remove the quotation marks around all column names, or change 'filename' to `filename`. Then it should work.

I had the same problem while using a button to sync a list from the server: 1) I click the button 2) A progress dialog shows up while dowloading the list from server 3) I turn the device to another orientation 4) java.lang.IllegalArgumentException: View not attached to window manager on postExecute() of the AsyncTask during progress.dismiss().

As I tried the fix I figured that even if the problem doesn't occur my list wasn't showing all items.

I figured that what I wanted was for the AsyncTask to finish (and dismiss the dialog) before the activity beign destroyed, so I made the asynctask object an attribute and overrided the onDestroy() method.

If the asynctask takes a lot of time the user maybe will feel that the device is slow, but I think that's the price he pays for trying to change the device orientation while the progress dialog is showing up. And even if it takes some time the app doesn't crash.

private AsyncTask<Boolean, Void, Boolean> atask;

@Override
protected void onDestroy() {
    if (atask!=null)
        try {
            atask.get();
        } catch (InterruptedException e) {
        } catch (ExecutionException e) {
        }
    super.onDestroy();
}

So, after a while of searching, and finding out that strtol is quite slow, I've coded my own function. It only works for uppercase on letters, but adding lowercase functionality ain't a problem.

int hexToInt(PCHAR _hex, int offset = 0, int size = 6)
{
    int _result = 0;
    DWORD _resultPtr = reinterpret_cast<DWORD>(&_result);
    for(int i=0;i<size;i+=2)
    {
        int _multiplierFirstValue = 0, _addonSecondValue = 0;

        char _firstChar = _hex[offset + i];
        if(_firstChar >= 0x30 && _firstChar <= 0x39)
            _multiplierFirstValue = _firstChar - 0x30;
        else if(_firstChar >= 0x41 && _firstChar <= 0x46)
            _multiplierFirstValue = 10 + (_firstChar - 0x41);

        char _secndChar = _hex[offset + i + 1];
        if(_secndChar >= 0x30 && _secndChar <= 0x39)
            _addonSecondValue = _secndChar - 0x30;
        else if(_secndChar >= 0x41 && _secndChar <= 0x46)
            _addonSecondValue = 10 + (_secndChar - 0x41);

        *(BYTE *)(_resultPtr + (size / 2) - (i / 2) - 1) = (BYTE)(_multiplierFirstValue * 16 + _addonSecondValue);
    }
    return _result;
}

Usage:

char *someHex = "#CCFF00FF";
int hexDevalue = hexToInt(someHex, 1, 8);

1 because the hex we want to convert starts at offset 1, and 8 because it's the hex length.

You can't restyle the default MessageBox as that's dependant on the current Windows OS theme, however you can easily create your own MessageBox. Just add a new form (i.e. MyNewMessageBox) to your project with these settings:

FormBorderStyle    FixedToolWindow
ShowInTaskBar      False
StartPosition      CenterScreen

To show it use myNewMessageBoxInstance.ShowDialog();. And add a label and buttons to your form, such as OK and Cancel and set their DialogResults appropriately, i.e. add a button to MyNewMessageBox and call it btnOK. Set the DialogResult property in the property window to DialogResult.OK. When that button is pressed it would return the OK result:

MyNewMessageBox myNewMessageBoxInstance = new MyNewMessageBox();
DialogResult result = myNewMessageBoxInstance.ShowDialog();
if (result == DialogResult.OK)
{
    // etc
}

It would be advisable to add your own Show method that takes the text and other options you require:

public DialogResult Show(string text, Color foreColour)
{
     lblText.Text = text;
     lblText.ForeColor = foreColour;
     return this.ShowDialog();
}

You can use android's inbuilt Patterns:

public boolean validCellPhone(String number)
{
    return android.util.Patterns.PHONE.matcher(number).matches();
}

This pattern is intended for searching for things that look like they might be phone numbers in arbitrary text, not for validating whether something is in fact a phone number. It will miss many things that are legitimate phone numbers.

The pattern matches the following:

• Optionally, a + sign followed immediately by one or more digits. Spaces, dots, or dashes may follow.
• Optionally, sets of digits in parentheses, separated by spaces, dots, or dashes.
• A string starting and ending with a digit, containing digits, spaces, dots, and/or dashes.

Wouldn't Collections.disjoint(A, B) work? From the documentation:

Returns true if the two specified collections have no elements in common.

Thus, the method returns false if the collections contains any common elements.

If you want to keep summing the digits until you get a single-digit number (one of my favorite characteristics of numbers divisible by 9) you can do:

def digital_root(n):
    x = sum(int(digit) for digit in str(n))
    if x < 10:
        return x
    else:
        return digital_root(x)

Which actually turns out to be pretty fast itself...

%timeit digital_root(12312658419614961365)

IF your data won't overflow 4000 characters AND you're on SQL Server 2000 or compatibility level of 8 or SQL Server 2000:

UPDATE [CMS_DB_test].[dbo].[cms_HtmlText] 
SET Content = CAST(REPLACE(CAST(Content as NVarchar(4000)),'ABC','DEF') AS NText)
WHERE Content LIKE '%ABC%' 

For SQL Server 2005+:

UPDATE [CMS_DB_test].[dbo].[cms_HtmlText] 
SET Content = CAST(REPLACE(CAST(Content as NVarchar(MAX)),'ABC','DEF') AS NText)
WHERE Content LIKE '%ABC%' 

Use onKeyDown event, and inside that check the key code of the key pressed by user. Key code of Enter key is 13, check the code and put the logic there.

Check this example:

class CartridgeShell extends React.Component {_x000D_
_x000D_
   constructor(props) {_x000D_
      super(props);_x000D_
      this.state = {value:''}_x000D_
_x000D_
      this.handleChange = this.handleChange.bind(this);_x000D_
      this.keyPress = this.keyPress.bind(this);_x000D_
   } _x000D_
 _x000D_
   handleChange(e) {_x000D_
      this.setState({ value: e.target.value });_x000D_
   }_x000D_
_x000D_
   keyPress(e){_x000D_
      if(e.keyCode == 13){_x000D_
         console.log('value', e.target.value);_x000D_
         // put the login here_x000D_
      }_x000D_
   }_x000D_
_x000D_
   render(){_x000D_
      return(_x000D_
         <input value={this.state.value} onKeyDown={this.keyPress} onChange={this.handleChange} fullWidth={true} />_x000D_
      )_x000D_
    }_x000D_
}_x000D_
_x000D_

<div id = 'app' />

Note: Replace the input element by Material-Ui TextField and define the other properties also.

You should write in this way

public function up()
{
    Schema::create('transactions', function (Blueprint $table) {
        $table->bigIncrements('id');
        $table->float('amount', 11, 2);
        $table->enum('transaction type', ['debit', 'credit']);
        $table->bigInteger('customer_id')->unsigned();      
        $table->timestamps();                 
    });

    Schema::table('transactions', function($table) {
        $table->foreign('customer_id')
              ->references('id')->on('customers')
              ->onDelete('cascade');
    });     
}

The foreign key field should be unsigned, hope it helps!!

Try the following:

List<Map<String, ArrayList<String>>> mapList = 
    new ArrayList<Map<String, ArrayList<String>>>();
mapList.add(map);

If your list must be of type List<HashMap<String, ArrayList<String>>>, then declare your map variable as a HashMap and not a Map.

You can try

Subject[] subjects = new Subject[2];
subjects[0] = new Subject{....};
subjects[1] = new Subject{....};

alternatively you can use List

List<Subject> subjects = new List<Subject>();
subjects.add(new Subject{....});
subjects.add(new Subject{....});

I think the best way to solve this problem is:

l = [1, 2, 3, 0, 0, 1]
while 0 in l:
    l.remove(0)

Instead of iterating over list I remove 0 until there aren't any 0 in list

Be aware: this function won't copy attributes of initial foreign key. It only takes foreign table name / column name, drops current key and replaces with new one.

You can use the getGraphics method of the component on which you would like to draw. This in turn should allow you to draw lines and make other things which are available through the Graphics class

You can also set the color individually for each point/bar if you change the data array to be configuration objects instead of numbers.

data: [
      {y: 34.4, color: 'red'},     // this point is red
      21.8,                        // default blue
      {y: 20.1, color: '#aaff99'}, // this will be greenish
      20]                          // default blue

I will avoid iterator as they can add/remove object during iteration, also for clean code use for loop. it will be simply clean & fewer lines.

Using Java 8 and Lamda [Update 4/2/2019]

import org.json.JSONObject;

public static void printJsonObject(JSONObject jsonObj) {
    jsonObj.keySet().forEach(keyStr ->
    {
        Object keyvalue = jsonObj.get(keyStr);
        System.out.println("key: "+ keyStr + " value: " + keyvalue);

        //for nested objects iteration if required
        //if (keyvalue instanceof JSONObject)
        //    printJsonObject((JSONObject)keyvalue);
    });
}

Using old way [Update 4/2/2019]

import org.json.JSONObject;

public static void printJsonObject(JSONObject jsonObj) {
    for (String keyStr : jsonObj.keySet()) {
        Object keyvalue = jsonObj.get(keyStr);

        //Print key and value
        System.out.println("key: "+ keyStr + " value: " + keyvalue);

        //for nested objects iteration if required
        //if (keyvalue instanceof JSONObject)
        //    printJsonObject((JSONObject)keyvalue);
    }
}

Original Answer

import org.json.simple.JSONObject;
public static void printJsonObject(JSONObject jsonObj) {
    for (Object key : jsonObj.keySet()) {
        //based on you key types
        String keyStr = (String)key;
        Object keyvalue = jsonObj.get(keyStr);

        //Print key and value
        System.out.println("key: "+ keyStr + " value: " + keyvalue);

        //for nested objects iteration if required
        if (keyvalue instanceof JSONObject)
            printJsonObject((JSONObject)keyvalue);

For those of you who just want to allow max. 2 <br> in a row, you can use this:

let text = text.replace(/(\r?\n){2,}/g, '<br><br>');
text = text.replace(/(\r?\n)/g, '<br>');

First line: Search for \n OR \r\n where at least 2 of them are in a row, e.g. \n\n\n\n. Then replace it with 2 br

Second line: Search for all single \r\n or \n and replace them with <br>

Does not work for multidimensional arrays, because references are used here.

import numpy as np

# swaps
data = np.random.random(2)
print(data)
data[0], data[1] = data[1], data[0]
print(data)

# does not swap
data = np.random.random((2, 2))
print(data)
data[0], data[1] = data[1], data[0]
print(data)

I've had some problems sending emails from my gmail account too, which were due to several of the aforementioned situations. Here's a summary of how I got it working, and keeping it flexible at the same time:

• First of all setup your GMail account:
  • Enable IMAP and assert the right maximum number of messages (you can do so here)
  • Make sure your password is at least 7 characters and is strong (according to Google)
  • Make sure you don't have to enter a captcha code first. You can do so by sending a test email from your browser.
• Make changes in web.config (or app.config, I haven't tried that yet but I assume it's just as easy to make it work in a windows application):

<configuration>
    <appSettings>
        <add key="EnableSSLOnMail" value="True"/>   
    </appSettings>

    <!-- other settings --> 

    ...

    <!-- system.net settings -->
    <system.net>
        <mailSettings>
            <smtp from="[email protected]" deliveryMethod="Network">
                <network 
                    defaultCredentials="false" 
                    host="smtp.gmail.com" 
                    port="587" 
                    password="stR0ngPassW0rd" 
                    userName="[email protected]"
                    />
                <!-- When using .Net 4.0 (or later) add attribute: enableSsl="true" and you're all set-->
            </smtp>
        </mailSettings>
    </system.net>
</configuration>

Add a Class to your project:

Imports System.Net.Mail

Public Class SSLMail

    Public Shared Sub SendMail(ByVal e As System.Web.UI.WebControls.MailMessageEventArgs)

        GetSmtpClient.Send(e.Message)

        'Since the message is sent here, set cancel=true so the original SmtpClient will not try to send the message too:
        e.Cancel = True

    End Sub

    Public Shared Sub SendMail(ByVal Msg As MailMessage)
        GetSmtpClient.Send(Msg)
    End Sub

    Public Shared Function GetSmtpClient() As SmtpClient

        Dim smtp As New Net.Mail.SmtpClient
        'Read EnableSSL setting from web.config
        smtp.EnableSsl = CBool(ConfigurationManager.AppSettings("EnableSSLOnMail"))
        Return smtp
    End Function

End Class

And now whenever you want to send emails all you need to do is call SSLMail.SendMail:

e.g. in a Page with a PasswordRecovery control:

Partial Class RecoverPassword
Inherits System.Web.UI.Page

Protected Sub RecoverPwd_SendingMail(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.MailMessageEventArgs) Handles RecoverPwd.SendingMail
    e.Message.Bcc.Add("[email protected]")
    SSLMail.SendMail(e)
End Sub

End Class

Or anywhere in your code you can call:

SSLMail.SendMail(New system.Net.Mail.MailMessage("[email protected]","[email protected]", "Subject", "Body"})

I hope this helps anyone who runs into this post! (I used VB.NET but I think it's trivial to convert it to any .NET language.)

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);


    //setting screen orientation locked so it will be acting as potrait
    setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LOCKED);
}

The lambda:

() -> { System.out.println("Do nothing!"); };

actually represents an implementation for an interface like:

public interface Something {
    void action();
}

which is completely different than the one you've defined. That's why you get an error.

Since you can't extend your @FunctionalInterface, nor introduce a brand new one, then I think you don't have much options. You can use the Optional<T> interfaces to denote that some of the values (return type or method parameter) is missing, though. However, this won't make the lambda body simpler.

Use:

#include <iostream>

...

std::cout << std::hex << a;

There are many other options to control the exact formatting of the output number, such as leading zeros and upper/lower case.

Just try with:

var check = moment(n.entry.date_entered, 'YYYY/MM/DD');

var month = check.format('M');
var day   = check.format('D');
var year  = check.format('YYYY');

JSFiddle

Note: Most modern browsers will now allow you to navigate objects in the developer console. This answer is antiquated.

This method will walk through object properties and write them to the console with increasing indent:

function enumerate(o,s){

    //if s isn't defined, set it to an empty string
    s = typeof s !== 'undefined' ? s : "";

    //if o is null, we need to output and bail
    if(typeof o == "object" && o === null){

       console.log(s+k+": null");

    } else {    

        //iterate across o, passing keys as k and values as v
        $.each(o, function(k,v){

            //if v has nested depth
           if(typeof v == "object" && v !== null){

                //write the key to the console
                console.log(s+k+": ");

                //recursively call enumerate on the nested properties
                enumerate(v,s+"  ");

            } else {

                //log the key & value
                console.log(s+k+": "+String(v));
            }
        });
    }
}

Just pass it the object you want to iterate through:

    var response = $.ajax({
        url: myurl,
        dataType: "json"
    })
    .done(function(a){
       console.log("Returned values:");
       enumerate(a);
    })
    .fail(function(){ console.log("request failed");});

If you have already made some commits, you can do the following

git pull --rebase

This will place all your local commits on top of newly pulled changes.

BE VERY CAREFUL WITH THIS: this will probably overwrite all your present files with the files as they are at the head of the branch in the remote repo! If this happens and you didn't want it to you can UNDO THIS CHANGE with

git rebase --abort 

... naturally you have to do that before doing any new commits!

By using Chrome or Opera

without any plugins, without writing any single XPath syntax character

1. right click the required element, then "inspect"
2. right click on highlighted element tag, choose Copy ? Copy XPath.

;)

You can also use truncate.

truncate table table_name;

Also, you can overwrite some variables:

s = input('UPPER CASE')
lower = s.lower()

If you use like this:

s = "Kilometer"
print(s.lower())     - kilometer
print(s)             - Kilometer

It will work just when called.

I had the same problem and thought I would post in case someone else runs into something similar.

In my case, I had attached a long press gesture recognizer to my UITableViewController.

UILongPressGestureRecognizer *longPressGesture = [[[UILongPressGestureRecognizer alloc]
                                                   initWithTarget:self
                                                   action:@selector(onLongPress:)]
                                                  autorelease];
[longPressGesture setMinimumPressDuration:1];
[self.tableView addGestureRecognizer:longPressGesture];

In my onLongPress selector, I launched my next view controller.

- (IBAction)onLongPress:(id)sender {

    SomeViewController* page = [[SomeViewController alloc] initWithNibName:@"SomeViewController" bundle:nil];

    [self.navigationController pushViewController:page animated:YES];

    [page release];

}

In my case, I received the error message because the long press recognizer fired more than one time and as a result, my "SomeViewController" was pushed onto the stack multiple times.

The solution was to add a boolean to indicate when the SomeViewController had been pushed onto the stack. When my UITableViewController's viewWillAppear method was called, I set the boolean back to NO.

I'm not sure how browsers handle clicks on type="file" elements (security concerns and all), but this should work:

$('input[type="file"]').click();

I've tested this JSFiddle in Chrome, Firefox and Opera and they all show the file browse dialog.

In your git dir, suppose you have sync all changes.

rm -rf .git 

rm -rf .gitmodules

Then do:

git init
git submodule add url_to_repo projectfolder

I think using react-native-responsive-dimensions might help you a little better on your case.

You can still get:

device-width by using and responsiveScreenWidth(100)

and

device-height by using and responsiveScreenHeight(100)

You also can more easily arrange the locations of your absolute components by setting margins and position values with proportioning it over 100% of the width and height

Just an update to this, Thierry's answer is still correct, but there has been an update to Angular2 with regards to:

<ul *ngFor="let item of items; let i = index" [attr.data-index]="i">
  <li>{{item}}</li>
</ul>

The #i = index should now be let i = index

EDIT/UPDATE:

The *ngFor should be on the element you're wanting to foreach, so for this example it should be:

<ul>
  <li *ngFor="let item of items; let i = index" [attr.data-index]="i">{{item}}</li>
</ul>

EDIT/UPDATE

Angular 5

<ul>
  <li *ngFor="let item of items; index as i" [attr.data-index]="i">{{item}}</li>
</ul>

EDIIT/UPDATE

Angular 7/8

<ul *ngFor="let item of items; index as i">
  <li [attr.data-index]="i">{{item}}</li>
</ul>

Use assets like a filesystem to dump any kind of files. And use res to store what it is made for, layouts, images, values.

Use a format string to round up to two decimal places and convert the double to a String:

let currentRatio = Double (rxCurrentTextField.text!)! / Double (txCurrentTextField.text!)!
railRatioLabelField.text! = String(format: "%.2f", currentRatio)

Example:

let myDouble = 3.141
let doubleStr = String(format: "%.2f", myDouble) // "3.14"

If you want to round up your last decimal place, you could do something like this (thanks Phoen1xUK):

let myDouble = 3.141
let doubleStr = String(format: "%.2f", ceil(myDouble*100)/100) // "3.15"

Here it is: http://jsfiddle.net/tQyvp/

Here's the code if you don't like going to jsfiddle:

html

<input id="myinputfield" value="This is some text" type="button">?

Javascript:

$('body').on('click', '#myinputfield', function(){
    var textField = $('#myinputfield');
    textField.val(textField.val()+' after clicking')       
});?

Merging several answers from above into an easy to use function

function GetScriptIfNotLoaded(scriptLocationAndName)
{
  var len = $('script[src*="' + scriptLocationAndName +'"]').length;

  //script already loaded!
  if (len > 0)
      return;

  var head = document.getElementsByTagName('head')[0];
  var script = document.createElement('script');
  script.type = 'text/javascript';
  script.src = scriptLocationAndName;
  head.appendChild(script);
}

Mine is using LOCATE in mysql:

LOCATE(substr,str), LOCATE(substr,str,pos)

This function is multi-byte safe, and is case-sensitive only if at least one argument is a binary string.

In your case:

mysql_query("
SELECT * FROM `table`
WHERE LOCATE('{$needle}','column') > 0
");

In my case I was able to fix that issue by using min-width: 100px instead of width: 100px for the cells th or td.

.table td, .table th {
    min-width: 100px;
}

On top of everything that's been said (

), which is correct, TFS isn't just a VCS. One major feature that TFS provides is natively integrated bug tracking functionality. Changesets are linked to issues and could be tracked. Various policies for check-ins are supported, as well as integration with Windows domain, which is what people who run TFS have. Tightly integrated GUI with Visual Studio is another selling point, which appeals to less than average mouse and click developer and his manager.

Hence comparing Git to TFS isn't a proper question to ask. Correct, though impractical, question is to compare Git with just VCS functionality of TFS. At that, Git blows TFS out of the water. However, any serious team needs other tools and this is where TFS provides one stop destination.

The Best way is to use closedxml. Below is the link for reference

https://closedxml.codeplex.com/wikipage?title=Adding%20DataTable%20as%20Worksheet&referringTitle=Documentation

and you can simple use

    var wb = new ClosedXML.Excel.XLWorkbook();
DataTable dt = GeDataTable();//refer documentaion

wb.Worksheets.Add(dt);

Response.Clear();
Response.ContentType = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet";
Response.AddHeader("content-disposition", "attachment;filename=\"FileName.xlsx\"");

using (var ms = new System.IO.MemoryStream()) {
    wb.SaveAs(ms);
    ms.WriteTo(Response.OutputStream);
    ms.Close();
}

Response.End();

A quick and copy/paste you can use for Chrome and Firefox would be: (change the stuff after the # to change the color)

-moz-border-radius: 10px;
-webkit-border-radius: 10px;
-khtml-border-radius: 10px;
-border-radius: 10px;
-moz-box-shadow: 0 0 15px 5px #666;
-webkit-box-shadow: 0 0 15px 05px #666;

Matt Roberts' answer is correct for webkit browsers (safari, chrome, etc), but I thought someone out there might want a quick answer rather than be told to learn to program to make some shadows.

The python-dateutil package can parse not only RFC 3339 datetime strings like the one in the question, but also other ISO 8601 date and time strings that don't comply with RFC 3339 (such as ones with no UTC offset, or ones that represent only a date).

>>> import dateutil.parser
>>> dateutil.parser.isoparse('2008-09-03T20:56:35.450686Z') # RFC 3339 format
datetime.datetime(2008, 9, 3, 20, 56, 35, 450686, tzinfo=tzutc())
>>> dateutil.parser.isoparse('2008-09-03T20:56:35.450686') # ISO 8601 extended format
datetime.datetime(2008, 9, 3, 20, 56, 35, 450686)
>>> dateutil.parser.isoparse('20080903T205635.450686') # ISO 8601 basic format
datetime.datetime(2008, 9, 3, 20, 56, 35, 450686)
>>> dateutil.parser.isoparse('20080903') # ISO 8601 basic format, date only
datetime.datetime(2008, 9, 3, 0, 0)

Note that dateutil.parser.isoparse is presumably stricter than the more hacky dateutil.parser.parse, but both of them are quite forgiving and will attempt to interpret the string that you pass in. If you want to eliminate the possibility of any misreads, you need to use something stricter than either of these functions.

The Pypi name is python-dateutil, not dateutil (thanks code3monk3y):

pip install python-dateutil

If you're using Python 3.7, have a look at this answer about datetime.datetime.fromisoformat.

With:

global index_add_counter

You are not defining, just declaring so it's like saying there is a global index_add_counter variable elsewhere, and not create a global called index_add_counter. As you name don't exists, Python is telling you it can not import that name. So you need to simply remove the global keyword and initialize your variable:

index_add_counter = 0

Now you can import it with:

from app import index_add_counter

The construction:

global index_add_counter

is used inside modules' definitions to force the interpreter to look for that name in the modules' scope, not in the definition one:

index_add_counter = 0
def test():
  global index_add_counter # means: in this scope, use the global name
  print(index_add_counter)

Here Is my snippet try it. I hope it will helpfull for u.

Similar to getting the length of a dataframe, len(df), the following worked for pandas and blaze:

Total = sum(df['MyColumn'])

or alternatively

Total = sum(df.MyColumn)
print Total

if user find particular array elements then use below code same as integer value.

var arrelemnts = ["sachin", "test", "test1", "test3"]

 if arrelemnts.contains("test"){
    print("found")   }else{

The + (String Concatenation) does not work on SQL Server for the image, ntext, or text data types.

In fact, image, ntext, and text are all deprecated.

ntext, text, and image data types will be removed in a future version of MicrosoftSQL Server. Avoid using these data types in new development work, and plan to modify applications that currently use them. Use nvarchar(max), varchar(max), and varbinary(max) instead.

That said if you are using an older version of SQL Server than you want to use UPDATETEXT to perform your concatenation. Which Colin Stasiuk gives a good example of in his blog post String Concatenation on a text column (SQL 2000 vs SQL 2005+).

If key is present table.put(key, val) will just overwrite the value else it'll create a new entry. Poof! and you are done. :)

you can get the value from a map by using key is table.get(key); That's about it

{{#each array}}
  {{@index}}
{{/each}}

I can see many good answers to the question, but I still would like to share this method, by using Git parameter as follows:

When building the pipeline you will be asked to choose the branch:

After that through the groovy code you could specify the branch you want to clone:

git branch:BRANCH[7..-1], url: 'https://github.com/YourName/YourRepo.git' , credentialsId: 'github' 

Note that I'm using a slice from 7 to the last character to shrink "origin/" and get the branch name.

Also in case you configured a webhooks trigger it still work and it will take the default branch you specified(master in our case).

An int is not null, it may be 0 if not initialized.

If you want an integer to be able to be null, you need to use Integer instead of int.

Integer id;
String name;

public Integer getId() { return id; }

Besides the statement if(person.equals(null)) can't be true, because if person is null, then a NullPointerException will be thrown. So the correct expression is if (person == null)

Add one detail to @J.F. Sebastian's and @Mark Mikofski's answers:
If one wants to get the corresponding indices (rather than the actual values of array), the following code will do:

For satisfying multiple (all) conditions:

select_indices = np.where( np.logical_and( x > 1, x < 5) )[0] #   1 < x <5

For satisfying multiple (or) conditions:

select_indices = np.where( np.logical_or( x < 1, x > 5 ) )[0] # x <1 or x >5

I believe it would be like this

takedata.match(/(\[.+\])/g);

the g at the end means global, so it doesn't stop at the first match.

Since Beautiful Soup 4.4.0. a parameter called string does the work that text used to do in the previous versions.

string is for finding strings, you can combine it with arguments that find tags: Beautiful Soup will find all tags whose .string matches your value for the string. This code finds the tags whose .string is “Elsie”:

soup.find_all("td", string="Elsie")

For more information about string have a look this section https://www.crummy.com/software/BeautifulSoup/bs4/doc/#the-string-argument

The unique name identifier applies to radio buttons:

<input type="radio" />

change your checkboxes to radio and everything should be working

Or simply Use union, for simple array.

_.union([1,2,3,3], [3,5])

// [1,2,3,5]

DO it like

$query = mysql_query("SELECT * FROM table WHERE the_number LIKE '$yourPHPVAR%'");

Do not forget the % at the end

For MVC3 you don't have to add any dummy files to set a certain browser. All you have to do is:

• "Show all files" for the project
• go to bin folder
• right click the only .xml file to find the "Browse With..." option

C:\>FORFILES  /C "cmd /c echo @fname @fsize"


C:\>FORFILES  /?

FORFILES [/P pathname] [/M searchmask] [/S]
         [/C command] [/D [+ | -] {MM/dd/yyyy | dd}]

Description:
    Selects a file (or set of files) and executes a
    command on that file. This is helpful for batch jobs.

Parameter List:
    /P    pathname      Indicates the path to start searching.
                        The default folder is the current working
                        directory (.).

You have two options for concatenating strings in Oracle:

• CONCAT
• Using ||

CONCAT example:

CONCAT(
  CONCAT(
    CONCAT(
      CONCAT(
        CONCAT('I like ', t.type_desc_column), 
        ' cake with '), 
      t.icing_desc_column),
    ' and a '),
  t.fruit_desc_column)

Using || example:

'I like ' || t.type_desc_column || ' cake with ' || t.icing_desc_column || ' and a ' || t.fruit_desc_column

Here is a simple example. I suppose it will be easy to understand:

import java.awt.*;
import javax.swing.JFrame;
import javax.swing.JPanel;

public class Graph extends JFrame {
JFrame f = new JFrame();
JPanel jp;


public Graph() {
    f.setTitle("Simple Drawing");
    f.setSize(300, 300);
    f.setDefaultCloseOperation(EXIT_ON_CLOSE);

    jp = new GPanel();
    f.add(jp);
    f.setVisible(true);
}

public static void main(String[] args) {
    Graph g1 = new Graph();
    g1.setVisible(true);
}

class GPanel extends JPanel {
    public GPanel() {
        f.setPreferredSize(new Dimension(300, 300));
    }

    @Override
    public void paintComponent(Graphics g) {
        //rectangle originates at 10,10 and ends at 240,240
        g.drawRect(10, 10, 240, 240);
        //filled Rectangle with rounded corners.    
        g.fillRoundRect(50, 50, 100, 100, 80, 80);
    }
}

}

And the output looks like this:

__getitem__ can be used to implement "lazy" dict subclasses. The aim is to avoid instantiating a dictionary at once that either already has an inordinately large number of key-value pairs in existing containers, or has an expensive hashing process between existing containers of key-value pairs, or if the dictionary represents a single group of resources that are distributed over the internet.

As a simple example, suppose you have two lists, keys and values, whereby {k:v for k,v in zip(keys, values)} is the dictionary that you need, which must be made lazy for speed or efficiency purposes:

class LazyDict(dict):
    
    def __init__(self, keys, values):
        self.keys = keys
        self.values = values
        super().__init__()
        
    def __getitem__(self, key):
        if key not in self:
            try:
                i = self.keys.index(key)
                self.__setitem__(self.keys.pop(i), self.values.pop(i))
            except ValueError, IndexError:
                raise KeyError("No such key-value pair!!")
        return super().__getitem__(key)

Usage:

>>> a = [1,2,3,4]
>>> b = [1,2,2,3]
>>> c = LazyDict(a,b)
>>> c[1]
1
>>> c[4]
3
>>> c[2]
2
>>> c[3]
2
>>> d = LazyDict(a,b)
>>> d.items()
dict_items([])

So, not directly related but this is the first question that appears when you try to find how to terminate a process running from a specific folder using Python.

It also answers the question in a way(even though it is an old one with lots of answers).

While creating a faster way to scrape some government sites for data I had an issue where if any of the processes in the pool got stuck they would be skipped but still take up memory from my computer. This is the solution I reached for killing them, if anyone knows a better way to do it please let me know!

        temp['id'].append(process.ProcessId)
        temp['path'].append(process.ExecutablePath)
        temp['name'].append(process.Name)
    temp = pd.DataFrame(temp)
    temp = temp.dropna(subset=['path']).reset_index().drop(columns=['index'])
    temp = temp.loc[temp['path'].str.contains(esc)].loc[temp.name.isin(execs)].reset_index().drop(columns=['index'])
    [os.system('taskkill /PID {} /f'.format(t)) for t in temp['id']]

            let cell = tableReport.dequeueReusableCell(withIdentifier: "Cell", for: indexPath)
            cell.textLabel?.text = "Report Name"
            return cell;
        }
}

I'm not sure what you mean by "myself".

Any JavaScript function can be called by an event, but you must have some sort of event to trigger it.

e.g. On page load:

<body onload="myfunction();">

Or on mouseover:

<table onmouseover="myfunction();">

As a result the first question is, "What do you want to do to cause the function to execute?"

After you determine that it will be much easier to give you a direct answer.

All the other solutions require specifying a release/version number which obviously breaks automation.

This solution- currently tested and known to work with Github API v3- however can be used programmatically to grab the LATEST release without specifying any tag or release number and un-TARs the binary to an arbitrary name you specify in switch --one-top-level="pi-ap". Just swap-out user f1linux and repo pi-ap in below example with your own details and Bob's your uncle:

curl -L https://api.github.com/repos/f1linux/pi-ap/tarball | tar xzvf - --one-top-level="pi-ap" --strip-components 1

You can't use placeholders for column names, table names, data type names, or basically anything that isn't data.

You could use Directory.GetCurrentDirectory:

var path = Path.Combine(Directory.GetCurrentDirectory(), "\\fileName.txt");

Which will look for the file fileName.txt in the current directory of the application.

android:editable="false" should work, but it is deprecated, you should be using android:inputType="none" instead.

Alternatively, if you want to do it in the code you could do this :

EditText mEdit = (EditText) findViewById(R.id.yourid);
mEdit.setEnabled(false);

This is also a viable alternative :

EditText mEdit = (EditText) findViewById(R.id.yourid);
mEdit.setKeyListener(null);

If you're going to make your EditText non-editable, may I suggest using the TextView widget instead of the EditText, since using a EditText seems kind of pointless in that case.

EDIT: Altered some information since I've found that android:editable is deprecated, and you should use android:inputType="none", but there is a bug about it on android code; So please check this.

I tried all the above solutions, however none of them worked. If you're on linux/macOS i highly suggest using tsocks over an ssh tunnel. What you need in order to get this setup working is a machine where you can log in via ssh, and in addition to that a programm called tsocks installed.

The idea here is to create a dynamic tunnel via SSH (a socks5 proxy). We then configure tsocks to use this tunnel and to start our applications, in this case:

tsocks gem install ...

or to account for rails 3.0:

tsocks bundle install

A more detailed guide can be found under:

http://blog.byscripts.info/2011/04/bypass-a-proxy-with-ssh-tunnel-and-tsocks-under-ubuntu/

Despite being written for Ubuntu the procedure should be applicable for all Unix based machines. An alternative to tsocks for Windows is FreeCap (http://www.freecap.ru/eng/). A viable SSH client on windows is called putty.

This is a special case, but if you're starting with a predefined hash that you want to grab and make a copy of, you can create a method that returns a hash:

def johns 
    {  "John"=>"Adams","Thomas"=>"Jefferson","Johny"=>"Appleseed"}
end

h1 = johns

The particular scenario that I had was I had a collection of JSON-schema hashes where some hashes built off others. I was initially defining them as class variables and ran into this copy issue.
