This is what I've come up for post order iterator:

    class PostOrderIterator
    implements Iterator<T> {

        private Stack<Node<T>> stack;
        private Node<T> prev;

        PostOrderIterator(Node<T> root) {
            this.stack = new Stack<>();
            recurse(root);
            this.prev = this.stack.peek();
        }

        private void recurse(Node<T> node) {
            if(node == null) {
                return;
            }

            while(node != null) {
                stack.push(node);
                node = node.left;
            }
            recurse(stack.peek().right);
        }

        @Override
        public boolean hasNext() {
            return !stack.isEmpty();
        }

        @Override
        public T next() {
            if(stack.peek().right != this.prev) {
                recurse(stack.peek().right);
            }

            Node<T> next = stack.pop();
            this.prev = next;
            return next.value;
        }
    }

Basically, the main idea is that you should think how the initialization process puts the first item to print on the top of the stack, while the rest of the stack follow the nodes that would have been touched by the recursion. The rest would just then become a lot easier to nail.

Also, from design perspective, PostOrderIterator is an internal class exposed via some factory method of the tree class as an Iterator<T>.

For those who are still looking for an answer. Here is a recursive approach to get the paths in a dictionary.

import os


def list_files(startpath):
    for root, dirs, files in os.walk(startpath):
        dir_content = []
        for dir in dirs:
            go_inside = os.path.join(startpath, dir)
            dir_content.append(list_files(go_inside))
        files_lst = []
        for f in files:
            files_lst.append(f)
        return {'name': root, 'files': files_lst, 'dirs': dir_content}

As of HTML5 browsers one can use inputElement.form - the value of the attribute must be an id of a <form> element in the same document. More info on MDN.

Using prevUntil() will allow us to get a distant sibling without having to get all. I had a particularly long set that was too CPU intensive using prevAll().

var category = $('li.current_sub').prev('li.par_cat');
if (category.length == 0){
  category = $('li.current_sub').prevUntil('li.par_cat').last().prev();
}
category.show();

This gets the first preceding sibling if it matches, otherwise it gets the sibling preceding the one that matches, so we just back up one more with prev() to get the desired element.

No need for jQuery.

JavaScript arrays have a find method, so you can achieve that in one line:

array.find((o) => { return o[propertyName] === propertyValue }

Example

const purposeObjects = [
    {purpose: "daily"},
    {purpose: "weekly"},
    {purpose: "monthly"}
];

purposeObjects.find((o) => { return o["purpose"] === "weekly" }

// output -> {purpose: "weekly"}

If you need IE compatibility, import this polyfill in your code.

// The string must contain at least one special character, escaping reserved RegEx characters to avoid conflict
  const hasSpecial = password => {
    const specialReg = new RegExp(
      '^(?=.*[!@#$%^&*"\\[\\]\\{\\}<>/\\(\\)=\\\\\\-_´+`~\\:;,\\.€\\|])',
    );
    return specialReg.test(password);
  };

window.scroll({top: 0, left: 0, behavior: 'smooth' });

Got it from an article about Smooth Scrolling.

If needed, there are some polyfills available.

Try add min-width: 100% to style of your textarea:

<textarea class="form-control" style="min-width: 100%"></textarea>

a little modification to @Cogwheel answer

public static bool IsValidEmail(this string email)
{
  // skip the exception & return early if possible
  if (email.IndexOf("@") <= 0) return false;

  try
  {
    var address = new MailAddress(email);
    return address.Address == email;
  }
  catch
  {
    return false;
  }
}

Do display:table; and set margin to auto

Important bit of code:

.relatedProducts {
    display: table;
    margin-left: auto;
    margin-right: auto;
}

No matter how many elements you got now it will auto align in center

Example in code snippet:

.relatedProducts {_x000D_
    display: table;_x000D_
    margin-left: auto;_x000D_
    margin-right: auto;_x000D_
}_x000D_
a {_x000D_
  text-decoration:none;_x000D_
}

<div class="row relatedProducts">_x000D_
<div class="homeContentTitle" style="margin: 100px auto 35px; width: 250px">Similar Products</div>_x000D_
     _x000D_
<a href="#">test1 </a>_x000D_
<a href="#">test2 </a>_x000D_
<a href="#">test3 </a>_x000D_
</div>

You can do as many Outlines as you like, and there's enough scope for coming up with lots of creative ideas.

Have fun!

Be careful with the syntax! Great Turtle used them interchangeably, but:

error_page 404 = /404.html;

Will return the 404.html page with a status code of 200 (because = has relayed that to this page)

error_page 404 /404.html;

Will return the 404.html page with a (the original) 404 error code.

I have experienced that it is not safe (VS2010) to delete[] NULL (i.e. array syntax). I'm not sure whether this is according to the C++ standard.

It is safe to delete NULL (scalar syntax).

Your code actually works on FF, it doesn't work on Chrome.

This works on FF and Chrome.

$(document).ready(function() {
        // Solution for disabling the submit temporarily for all the submit buttons.
        // Avoids double form submit.
        // Doing it directly on the submit click made the form not to submit in Chrome.
        // This works in FF and Chrome.
        $('form').on('submit', function(e){
          //console.log('submit2', e, $(this).find('[clicked=true]'));
          var submit = $(this).find('[clicked=true]')[0];
          if (!submit.hasAttribute('disabled'))
          {
            submit.setAttribute('disabled', true);
            setTimeout(function(){
              submit.removeAttribute('disabled');
            }, 1000);
          }
          submit.removeAttribute('clicked');
          e.preventDefault();
        });
        $('[type=submit]').on('click touchstart', function(){
          this.setAttribute('clicked', true);
        });
      });
    </script>

I have done it by the following way

1. Start cmd
2. Go to the "C:\Program Files\MySQL\MySQL Server 5.6\bin"
3. type mysqld --install

Like the following image. See for more information.

As TokenMacGuy says, you should use thread.is_alive() to check if a thread is still running. To remove no longer running threads from your list you can use a list comprehension:

for t in my_threads:
    if not t.is_alive():
        # get results from thread
        t.handled = True
my_threads = [t for t in my_threads if not t.handled]

This avoids the problem of removing items from a list while iterating over it.

You can use this function, ORACLE DB

 public string getMaximumSequenceOfUser(string columnName, string tableName, string username)
    {
        string result = "";
        var query = string.Format("Select MAX ({0})from {1} where CREATED_BY = {2}", columnName, tableName, username.ToLower());

        OracleConnection conn = new OracleConnection(_context.Database.Connection.ConnectionString);
        OracleCommand cmd = new OracleCommand(query, conn);
        try
        {
            conn.Open();
            OracleDataReader dr = cmd.ExecuteReader();
            dr.Read();
            result = dr[0].ToString();
            dr.Dispose();
        }
        finally
        {
            conn.Close();
        }
        return result;
    }

Try this:

select distinct a.FirstName, a.LastName, v.District
from AddTbl a 
  inner join ValTbl v
  on a.LastName = v.LastName
order by a.FirstName;

Or this (it does the same, but the syntax is different):

select distinct a.FirstName, a.LastName, v.District
from AddTbl a, ValTbl v
where a.LastName = v.LastName
order by a.FirstName;

I ran into this issue on a corporate development VM which wasn't running OpenVPN. Checking out etc/docker/daemon.json, I found

...
"default-address-pools": [
  {
    "base": "192.168.11.0/24",
    "size": 24
  }
],
...

Strangely, removing the default-address-pools field and then restarting docker with sudo systemctl restart docker fixed the issue for me. I'm assuming this let docker choose a more suitable default, but I don't know what the problem was with the chosen default.

Few other points which might be helpful to understand differences between local and session storage

1. Both local storage and session storage are scoped to document origin, so

   https://mydomain.com/
   http://mydomain.com/
   https://mydomain.com:8080/

   All of the above URL's will not share the same storage. (Notice path of the web page does not affect the web storage)

2. Session storage is different even for the document with same origin policy open in different tabs, so same web page open in two different tabs cannot share the same session storage.

3. Both local and session storage are also scoped by browser vendors. So storage data saved by IE cannot be read by Chrome or FF.

Hope this helps.

The Esentutl /y option allows copyng (single) file files with progress bar like this :

the command should look like :

esentutl /y "FILE.EXT" /d "DEST.EXT" /o

The command is available on every windows machine but the y option is presented in windows vista. As it works only with single files does not look very useful for a small ones. Other limitation is that the command cannot overwrite files. Here's a wrapper script that checks the destination and if needed could delete it (help can be seen by passing /h).

The SettingWithCopyWarning was created to flag potentially confusing "chained" assignments, such as the following, which does not always work as expected, particularly when the first selection returns a copy. [see GH5390 and GH5597 for background discussion.]

df[df['A'] > 2]['B'] = new_val  # new_val not set in df

The warning offers a suggestion to rewrite as follows:

df.loc[df['A'] > 2, 'B'] = new_val

However, this doesn't fit your usage, which is equivalent to:

df = df[df['A'] > 2]
df['B'] = new_val

While it's clear that you don't care about writes making it back to the original frame (since you are overwriting the reference to it), unfortunately this pattern cannot be differentiated from the first chained assignment example. Hence the (false positive) warning. The potential for false positives is addressed in the docs on indexing, if you'd like to read further. You can safely disable this new warning with the following assignment.

import pandas as pd
pd.options.mode.chained_assignment = None  # default='warn'

The data containing the date column can be read by using the below code:

data = pd.csv(file_path,parse_dates=[date_column])

Once the data is read by using the above line of code, the column containing the information about the date can be accessed using pd.date_time() like:

pd.date_time(data[date_column], format = '%d/%m/%y')

to change the format of date as per the requirement.

In my case I'm calling an API hosted by AWS (API Gateway). The error happened when I tried to call the API from a domain other than the API own domain. Since I'm the API owner I enabled CORS for the test environment, as described in the Amazon Documentation.

In production this error will not happen, since the request and the api will be in the same domain.

I hope it helps!

Sometimes none of these would work for me. So I used to create a new web project in VS and select Authorization as "Individual User Accounts". I believe this work with some higher version of .NET Framework or something. But when you do this it will have your connection details. Mostly something like this

(LocalDb)\MSSQLLocalDB

You can use a Singleton Pattern like this:

package com.ramps;

public class MyProperties {
private static MyProperties mInstance= null;

public int someValueIWantToKeep;

protected MyProperties(){}

public static synchronized MyProperties getInstance() {
        if(null == mInstance){
            mInstance = new MyProperties();
        }
        return mInstance;
    }
}

In your application you can access your singleton in this way:

MyProperties.getInstance().someValueIWantToKeep

This is the way I prefer:

class Klass(object):

    @staticmethod
    def stat_func():
        return 42

    _ANS = stat_func.__func__()

    def method(self):
        return self.__class__.stat_func() + self.__class__._ANS

I prefer this solution to Klass.stat_func, because of the DRY principle. Reminds me of the reason why there is a new super() in Python 3 :)

But I agree with the others, usually the best choice is to define a module level function.

For instance with @staticmethod function, the recursion might not look very good (You would need to break DRY principle by calling Klass.stat_func inside Klass.stat_func). That's because you don't have reference to self inside static method. With module level function, everything will look OK.

You can wrap the Promise in a class.

class Deferred {
    constructor(handler) {
        this.promise = new Promise((resolve, reject) => {
            this.reject = reject;
            this.resolve = resolve;
            handler(resolve, reject);
        });

        this.promise.resolve = this.resolve;
        this.promise.reject = this.reject;

        return this.promise;
    }
    promise;
    resolve;
    reject;
}

// How to use.
const promise = new Deferred((resolve, reject) => {
  // Use like normal Promise.
});

promise.resolve(); // Resolve from any context.

You could also use something like that:

<div class="comeBack_up" *ngIf="isEmptyObject(previous_info)"  >

with the isEmptyObject method defined in your component:

isEmptyObject(obj) {
  return (obj && (Object.keys(obj).length === 0));
}

Integer has no method length. Try string

var testvar={};
testvar[1]="2";
alert(testvar[1].length);

You could try to save the image using this approach

SaveFileDialog dialog = new SaveFileDialog();
if (dialog.ShowDialog() == DialogResult.OK)
{
   int width = Convert.ToInt32(drawImage.Width); 
   int height = Convert.ToInt32(drawImage.Height); 
   Bitmap bmp = new Bitmap(width,height);        
   drawImage.DrawToBitmap(bmp, new Rectangle(0, 0, width, height);
   bmp.Save(dialog.FileName, ImageFormat.Jpeg);
}

It depends on the package. If the Makefile is generated by GNU autotools (./configure) you can usually set the target location like so:

./configure --prefix=/somewhere/else/than/usr/local

If the Makefile is not generated by autotools, but distributed along with the software, simply open it up in an editor and change it. The install target directory is probably defined in a variable somewhere.

Probably the most useful thing you could do is to peruse the online book [http://git-scm.com/book/en/]. It's really a pretty decent read and gives you the conceptual context with which to execute things properly.

Best way i learnt is using express with html files as express gives lots of advantage. Also you can extend it to a Heroku platform if you want..Just saying :)

var express = require("express");
var app     = express();
var path    = require("path");


app.get('/',function(req,res){
  res.sendFile(path.join(__dirname+'/index.html'));
});

app.listen(3000);



console.log("Running at Port 3000");

Clean and best..!!!

I have found better option,

<style type="text/css">
    .form {
        margin: 0 auto;
        width: 210px;
    }
    .form label{
        display: inline-block;
        text-align: right;
        float: left;
    }
    .form input{
        display: inline-block;
        text-align: left;
        float: right;
    }
</style>

Demo here: https://jsfiddle.net/durtpwvx/

That error means that a function call is only matched by an existing function if all its arguments are of the same type and passed in same order. So if the next f() function

create function f() returns integer as $$ 
    select 1;
$$ language sql;

is called as

select f(1);

It will error out with

ERROR:  function f(integer) does not exist
LINE 1: select f(1);
               ^
HINT:  No function matches the given name and argument types. You might need to add explicit type casts.

because there is no f() function that takes an integer as argument.

So you need to carefully compare what you are passing to the function to what it is expecting. That long list of table columns looks like bad design.

Since this thread is the first one from Google I found, one accurate and lazy way I found is :

const momentObject = moment().toObject();
// date doesn't exist with duration, but day does so use it instead
//   -1 because moment start from date 1, but a duration start from 0
const durationCompatibleObject = { ... momentObject, day: momentObject.date - 1 };
delete durationCompatibleObject.date;

const yourDuration = moment.duration(durationCompatibleObject);
// yourDuration.asMilliseconds()

now just add some prototypes (such as toDuration()) / .asMilliseconds() into moment and you can easily switch to milliseconds() or whatever !

Without extensions (cheat)

SELECT uuid_in(md5(random()::text || clock_timestamp()::text)::cstring);

output>> c2d29867-3d0b-d497-9191-18a9d8ee7830

(works at least in 8.4)

• Thanks to @Erwin Brandstetter for clock_timestamp() explanation.

If you need a valid v4 UUID

SELECT uuid_in(overlay(overlay(md5(random()::text || ':' || clock_timestamp()::text) placing '4' from 13) placing to_hex(floor(random()*(11-8+1) + 8)::int)::text from 17)::cstring);

* Thanks to @Denis Stafichuk @Karsten and @autronix

Also, in modern Postgres, you can simply cast:

SELECT md5(random()::text || clock_timestamp()::text)::uuid

The command has to be entered in the directory of the repository. The error is complaining that your current directory isn't a git repo

1. Are you in the right directory? Does typing ls show the right files?
2. Have you initialized the repository yet? Typed git init? (git-init documentation)

Either of those would cause your error.

Look at java.lang.BigDecimal, may solve your problem.

http://docs.oracle.com/javase/7/docs/api/java/math/BigDecimal.html

There's always a better way for doing things.

var number = 51.93999999999761;

I would like to get four digits precision: 51.94

just do:

number.toPrecision(4);

the result will be: 51.94

This will show image of base 64 data:

<style>
.logo {
      width: 290px;
      height: 63px;
      background: url(data:image/png;base64,copy-paste-base64-data-here) no-repeat;
}
</style>

<div class="logo"></div>

I solved the problem by cat'ing all the pems together:

cat cert.pem chain.pem fullchain.pem >all.pem
openssl pkcs12 -export -in all.pem -inkey privkey.pem -out cert_and_key.p12 -name tomcat -CAfile chain.pem -caname root -password MYPASSWORD
keytool -importkeystore -deststorepass MYPASSWORD -destkeypass MYPASSWORD -destkeystore MyDSKeyStore.jks -srckeystore cert_and_key.p12 -srcstoretype PKCS12 -srcstorepass MYPASSWORD -alias tomcat
keytool -import -trustcacerts -alias root -file chain.pem -keystore MyDSKeyStore.jks -storepass MYPASSWORD

(keytool didn't know what to do with a PKCS7 formatted key)

I got all the pems from letsencrypt

One neat trick to disable margin collapsing that has no visual impact, as far as I know, is setting the padding of the parent to 0.05px:

.parentClass {
    padding: 0.05px;
}

The padding is no longer 0 so collapsing won't occur anymore but at the same time the padding is small enough that visually it will round down to 0.

If some other padding is desired, then apply padding only to the "direction" in which margin collapsing is not desired, for example padding-top: 0.05px;.

Working example:

Edit: changed the value from 0.1 to 0.05. As Chris Morgan mentioned in a comment bellow, and from this small test, it seems that indeed Firefox takes the 0.1px padding into consideration. Though, 0.05px seemes to do the trick.

The best way is probably trying to open it, using just opendir() for instance.

Note that it's always best to try to use a filesystem resource, and handling any errors occuring because it doesn't exist, rather than just checking and then later trying. There is an obvious race condition in the latter approach.

Solved it. Turns out the column had a limited set of characters it would accept, changed it, and now the query works fine.

I think is better to change the logical function in the plugin. Around row 552 i change this:

            var zIndex = parseInt(this.element.parents().filter(function(){
                return $(this).css('z-index') !== 'auto';
            }).first().css('z-index'))+10;

into this:

            var zIndex = parseInt(this.element.parents().filter(function(){
                return $(this).css('z-index') !== 'auto';
            }).first().css('z-index')) + 10 * 1000; //think is enought

public static class GlobalVariables
{
    // readonly variable
    public static string Foo
    {
        get
        {
            return "foo";
        }
    }

    // read-write variable
    public static string Bar
    {
        get
        {
            return HttpContext.Current.Application["Bar"] as string;
        }
        set
        {
            HttpContext.Current.Application["Bar"] = value;
        }
    }
}

clock() returns the number of clock ticks since your program started. There is a related constant, CLOCKS_PER_SEC, which tells you how many clock ticks occur in one second. Thus, you can test any operation like this:

clock_t startTime = clock();
doSomeOperation();
clock_t endTime = clock();
clock_t clockTicksTaken = endTime - startTime;
double timeInSeconds = clockTicksTaken / (double) CLOCKS_PER_SEC;

From the document

npm-start :

This runs an arbitrary command specified in the package's "start" property of its "scripts" object. If no "start" property is specified on the "scripts" object, it will run node server.js.

which means it will call the start scripts inside the package.json

"scripts": {
"start": "tsc && concurrently \"npm run tsc:w\" \"npm run lite --baseDir ./app --port 8001\" ",
"lite": "lite-server",
 ...
}

ng serve:

Provided by angular/angular-cli to start angular2 apps which created by angular-cli. when you install angular-cli, it will create ng.cmd under C:\Users\name\AppData\Roaming\npm (for windows) and execute "%~dp0\node.exe" "%~dp0\node_modules\angular-cli\bin\ng" %*

So using npm start you can make your own execution where is ng serve is only for angular-cli

See Also : What happens when you run ng serve?

$host = $_SERVER['HTTP_HOST'];
preg_match("/[^\.\/]+\.[^\.\/]+$/", $host, $matches);
$domain = $matches[0];
$url = explode($domain, $host);
$subdomain = str_replace('.', '', $url[0]);

echo 'subdomain: '.$subdomain.'<br />';
echo 'domain: '.$domain.'<br />';

I belive the answer is:

echo date('Y-m-d H:i:s');

Modulus division is pretty simple. It uses the remainder instead of the quotient.

    1.0833... <-- Quotient
   __
12|13
   12
    1 <-- Remainder
    1.00 <-- Remainder can be used to find decimal values
     .96
     .040
     .036
     .0040 <-- remainder of 4 starts repeating here, so the quotient is 1.083333...

13/12 = 1R1, ergo 13%12 = 1.

It helps to think of modulus as a "cycle".

In other words, for the expression n % 12, the result will always be < 12.

That means the sequence for the set 0..100 for n % 12 is:

{0,1,2,3,4,5,6,7,8,9,10,11,0,1,2,3,4,5,6,7,8,9,10,11,0,[...],4}

In that light, the modulus, as well as its uses, becomes much clearer.

I often use the bibliography style natbib because it supplies quite complete set of formats as well as tags for us.

In OS X, too see the connections directly on the network interface, just do:

$ lsof -n -i4TCP:27017

Are you looking for something like this?

    COLUMN_NAMES=['A','B','C','D','E','F','G']
    df = pd.DataFrame(columns=COLUMN_NAMES)
    df.columns

   Index(['A', 'B', 'C', 'D', 'E', 'F', 'G'], dtype='object')

Assuming you have a list of object of type Person, using Lambda expression, you can sort the last names of users for instance by doing the following:

import java.util.Arrays;
import java.util.Collections;
import java.util.Comparator;
import java.util.List;

class Person {
        private String firstName;
        private String lastName;

        public Person(String firstName, String lastName){
            this.firstName = firstName;
            this.lastName = lastName;
        }

        public String getLastName(){
            return this.lastName;
        }

        public String getFirstName(){
            return this.firstName;
        }

        @Override
        public String toString(){
            return "Person: "+ this.getFirstName() + " " + this.getLastName();
        }
    }

    class TestSort {
        public static void main(String[] args){
            List<Person> people = Arrays.asList(
                                  new Person("John", "Max"), 
                                  new Person("Coolio", "Doe"), 
                                  new Person("Judith", "Dan")
            );

            //Making use of lambda expression to sort the collection
            people.sort((p1, p2)->p1.getLastName().compareTo(p2.getLastName()));

            //Print sorted 
            printPeople(people);
        }

        public static void printPeople(List<Person> people){
            for(Person p : people){
                System.out.println(p);
            }
        }
    }

You get the value of the textarea, use it :

$('.type').keyup(function() {
    var v = $('.type').val(); // you'd better use this.value here
    if (v.indexOf('> <')!=-1) {
       console.log('contains > <');        
    }
});

think of operator as unary function: is_false(type value) which returns true or false, depending on the exact implementation for specific type and value. Consider if statement to invoke such function implicitly, via syntactic sugar.

other possibility is that type has cast operator, which turns type into another type implicitly, in this case string to Boolean.

PHP does not expose such details, but C++ allows operator overloading which exposes fine details of operator implementation.

x.each_with_index { |v, i| puts "current index...#{i}" }

To mark a lambda async, simply prepend async before its argument list:

// Add a command to delete the current Group
contextMenu.Commands.Add(new UICommand("Delete this Group", async (contextMenuCmd) =>
{
    SQLiteUtils slu = new SQLiteUtils();
    await slu.DeleteGroupAsync(groupName);
}));

These two ways can live together just fine and actually support each other.

Composition is just playing it modular: you create interface similar to the parent class, create new object and delegate calls to it. If these objects need not to know of each other, it's quite safe and easy to use composition. There are so many possibilites here.

However, if the parent class for some reason needs to access functions provided by the "child class" for inexperienced programmer it may look like it's a great place to use inheritance. The parent class can just call it's own abstract "foo()" which is overwritten by the subclass and then it can give the value to the abstract base.

It looks like a nice idea, but in many cases it's better just give the class an object which implements the foo() (or even set the value provided the foo() manually) than to inherit the new class from some base class which requires the function foo() to be specified.

Why?

Because inheritance is a poor way of moving information.

The composition has a real edge here: the relationship can be reversed: the "parent class" or "abstract worker" can aggregate any specific "child" objects implementing certain interface + any child can be set inside any other type of parent, which accepts it's type. And there can be any number of objects, for example MergeSort or QuickSort could sort any list of objects implementing an abstract Compare -interface. Or to put it another way: any group of objects which implement "foo()" and other group of objects which can make use of objects having "foo()" can play together.

I can think of three real reasons for using inheritance:

1. You have many classes with same interface and you want to save time writing them
2. You have to use same Base Class for each object
3. You need to modify the private variables, which can not be public in any case

If these are true, then it is probably necessary to use inheritance.

There is nothing bad in using reason 1, it is very good thing to have a solid interface on your objects. This can be done using composition or with inheritance, no problem - if this interface is simple and does not change. Usually inheritance is quite effective here.

If the reason is number 2 it gets a bit tricky. Do you really only need to use the same base class? In general, just using the same base class is not good enough, but it may be a requirement of your framework, a design consideration which can not be avoided.

However, if you want to use the private variables, the case 3, then you may be in trouble. If you consider global variables unsafe, then you should consider using inheritance to get access to private variables also unsafe. Mind you, global variables are not all THAT bad - databases are essentially big set of global variables. But if you can handle it, then it's quite fine.

This is simple with numpy.add()

import numpy

list1 = numpy.array([1, 2, 3])
list2 = numpy.array([4, 5, 6])
result = numpy.add(list1, list2) # result receive element-wise addition of list1 and list2
print(result)
array([5, 7, 9])

See doc here

If you want to receiver a python list:

result.tolist()

Some more options. In Ipython with pylab enabled, dedent is already in the namespace. I checked and it is from matplotlib. Or it can be imported with:

from matplotlib.cbook import dedent

In documentation it states that it is faster than the textwrap equivalent one and in my tests in ipython it is indeed 3 times faster on average with my quick tests. It also has the benefit that it discards any leading blank lines this allows you to be flexible in how you construct the string:

"""
line 1 of string
line 2 of string
"""

"""\
line 1 of string
line 2 of string
"""

"""line 1 of string
line 2 of string
"""

Using the matplotlib dedent on these three examples will give the same sensible result. The textwrap dedent function will have a leading blank line with 1st example.

Obvious disadvantage is that textwrap is in standard library while matplotlib is external module.

Some tradeoffs here... the dedent functions make your code more readable where the strings get defined, but require processing later to get the string in usable format. In docstrings it is obvious that you should use correct indentation as most uses of the docstring will do the required processing.

When I need a non long string in my code I find the following admittedly ugly code where I let the long string drop out of the enclosing indentation. Definitely fails on "Beautiful is better than ugly.", but one could argue that it is simpler and more explicit than the dedent alternative.

def example():
    long_string = '''\
Lorem ipsum dolor sit amet, consectetur adipisicing
elit, sed do eiusmod tempor incididunt ut labore et
dolore magna aliqua. Ut enim ad minim veniam, quis
nostrud exercitation ullamco laboris nisi ut aliquip.\
'''
    return long_string

SHOW TABLES only lists the non-TEMPORARY tables in a given database.

https://dev.mysql.com/doc/refman/5.0/en/show-tables.html

To get all tables with columns columnA or ColumnB in the database YourDatabase:

SELECT DISTINCT TABLE_NAME 
    FROM INFORMATION_SCHEMA.COLUMNS
    WHERE COLUMN_NAME IN ('columnA','ColumnB')
        AND TABLE_SCHEMA='YourDatabase';

One reason could be that the chosen ABI does not fit to your system. For me, only arm64 is working.

a bit change in format

format : "DD/MM/YYYY"

You can use text-center for the row and can make sure the internal divs have display:inline-block (with not float).

As:

<div class="container">
    <div class="row text-center" style="background-color : black;">
        <div class="redBlock">A red block</div>
        <div class="whiteBlock">A white block</div>
        <div class="yellowBlock">A yellow block</div>
    </div>
</div>

And CSS:

.redBlock {
    width: 100px;
    height: 100px;
    background-color: aqua;
    display: inline-block
}
.whiteBlock {
    width: 100px;
    height: 100px;
    background-color: white;
    display: inline-block
}
.yellowBlock {
    width: 100px;
    height: 100px;
    background-color: yellow;
    display: inline-block
}

Method call setSelectedIndex("item_value"); doesn't work because setSelectedIndex use sequential index.

For Visual Studio 2015 the connection string is:

"Data Source=(localdb)\MSSQLLocalDB;AttachDbFilename=|DataDirectory|Database1.mdf;Integrated Security=True"

You're giving parameters to your program instead to Java. Use

java -Dtest="true" -jar myApplication.jar 

instead.

Consider using

"true".equalsIgnoreCase(System.getProperty("test"))

to avoid the NPE. But do not use "Yoda conditions" always without thinking, sometimes throwing the NPE is the right behavior and sometimes something like

System.getProperty("test") == null || System.getProperty("test").equalsIgnoreCase("true")

is right (providing default true). A shorter possibility is

!"false".equalsIgnoreCase(System.getProperty("test"))

but not using double negation doesn't make it less hard to misunderstand.

Use offset() function of jQuery. Here it would be:

$container.offset({
        'left': 100,
        'top': mouse.y - ( event_state.mouse_y - event_state.container_top ) 
    });

Your tables should have as immediate children just tbody and thead elements, with the rows within*. So, amend the HTML to be:

<table border="1" width="100%" id="test">
  <tbody>
    <tr>
     <td>
      <table border="1" width="100%">
        <tbody>
          <tr>
            <td>table 2</td>
          </tr>
        </tbody>
      </table>
     </td>
    </tr> 
    <tr><td>table 1</td></tr>
    <tr><td>table 1</td></tr>
    <tr><td>table 1</td></tr>
  </tbody>
</table>

Then amend your selector slightly to this:

#test > tbody > tr:last-child { background:#ff0000; }

See it in action here. That makes use of the child selector, which:

...separates two selectors and matches only those elements matched by the second selector that are direct children of elements matched by the first.

So, you are targeting only direct children of tbody elements that are themselves direct children of your #test table.

Alternative solution

The above is the neatest solution, as you don't need to over-ride any styles. The alternative would be to stick with your current set-up, and over-ride the background style for the inner table, like this:

#test tr:last-child { background:#ff0000; }
#test table tr:last-child { background:transparent; }

* It's not mandatory but most (all?) browsers will add these in, so it's best to make it explicit. As @BoltClock states in the comments:

...it's now set in stone in HTML5, so for a browser to be compliant it basically must behave this way.

I've found a way to solve the problem. This is a nasty hack but it works: open the doc with Open Office, then save it into any excel format; the resulting .xls or .xlsx will display the accentuated characters.

There are three packagers, and two compilers:

free packager: PAR
commercial packagers: perl2exe, perlapp
compilers: B::C, B::CC

http://search.cpan.org/dist/B-C/perlcompile.pod

(Note: perlfaq3 is still wrong)

For strawberry you need perl-5.16 and B-C from git master (1.43), as B-C-1.42 does not support 5.16.

Did you try this ?

 $("*").click(function(){
    $(this).attr("id"); 
 });

How to make a simple Android popup window

This is a fuller example. It is a supplemental answer that deals with creating a popup window in general and not necessarily the specific details of the OP's problem. (The OP asks for a cancel button, but this is not necessary because the user can click anywhere on the screen to cancel it.) It will look like the following image.

Make a layout for the popup window

Add a layout file to res/layout that defines what the popup window will look like.

popup_window.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:background="#62def8">

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerInParent="true"
        android:layout_margin="30dp"
        android:textSize="22sp"
        android:text="This is a popup window."/>

</RelativeLayout>

Inflate and show the popup window

Here is the code for the main activity of our example. Whenever the button is clicked, the popup window is inflated and shown over the activity. Touching anywhere on the screen dismisses the popup window.

MainActivity.java

public class MainActivity extends AppCompatActivity {

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

    public void onButtonShowPopupWindowClick(View view) {

        // inflate the layout of the popup window
        LayoutInflater inflater = (LayoutInflater)
                getSystemService(LAYOUT_INFLATER_SERVICE);
        View popupView = inflater.inflate(R.layout.popup_window, null);

        // create the popup window
        int width = LinearLayout.LayoutParams.WRAP_CONTENT;
        int height = LinearLayout.LayoutParams.WRAP_CONTENT;
        boolean focusable = true; // lets taps outside the popup also dismiss it
        final PopupWindow popupWindow = new PopupWindow(popupView, width, height, focusable);

        // show the popup window
        // which view you pass in doesn't matter, it is only used for the window tolken
        popupWindow.showAtLocation(view, Gravity.CENTER, 0, 0);

        // dismiss the popup window when touched
        popupView.setOnTouchListener(new View.OnTouchListener() {
            @Override
            public boolean onTouch(View v, MotionEvent event) {
                popupWindow.dismiss();
                return true;
            }
        });
    }
}

That's it. You're finished.

You can also add a shadow.

Adding another option, if jq is available:

export NAMES="{
  \"Mary\":\"100\",
  \"John\":\"200\",
  \"Mary\":\"50\",
  \"John\":\"300\",
  \"Paul\":\"100\",
  \"Paul\":\"400\",
  \"David\":\"100\"
}"
export NAME=David
echo $NAMES | jq --arg v "$NAME" '.[$v]' | tr -d '"' 

You might find mimeTeX useful.

The 500 (internal server error) means something went wrong on the server's side. It could be several things, but I would start by verifying that the URL and parameters are correct. Also, make sure that whatever handles the request is expecting the request as a GET and not a POST.

One useful way to learn more about what's going on is to use a tool like Fiddler which will let you watch all HTTP requests and responses so you can see exactly what you're sending and the server is responding with.

If you don't have a compelling reason to write your own Ajax code, you would be far better off using a library that handles the Ajax interactions for you. jQuery is one option.

A late but useful answer, PHP has a function specifically for this purpose.

mb_strimwidth

$string = mb_strimwidth($string, 0, 100);
$string = mb_strimwidth($string, 0, 97, '...'); //optional characters for end

You could also use python reduce:

def deep_get(dictionary, *keys):
    return reduce(lambda d, key: d.get(key) if d else None, keys, dictionary)

Alternatively, can use for particular table

 <table style="width:1000px; height:100px;">
    <tr>
        <td align="center" valign="top">Text</td> //Remove it
        <td class="tableFormatter">Text></td>
    </tr>
</table>

Add this css in external file

.tableFormatter
{
width:100%;
vertical-align:top;
text-align:center;
}

Swift 4.2 example:

let group = DispatchGroup.group(count: 2)
group.notify(queue: DispatchQueue.main) {
     self.renderingLine = false
     // all groups are done
}
DispatchQueue.main.async {
    self.renderTargetNode(floorPosition: targetPosition, animated: closedContour) {
        group.leave()
        // first done
    }
    self.renderCenterLine(position: targetPosition, animated: closedContour) {
        group.leave()
        // second done
    }
 }

UPDATE: For Xcode 8.0+ you need to follow below Steps:

1. Download application from iTunes
2. Select downloaded app, right click show in finder
3. Copy .ipa file to Desktop, rename it to .zip file
4. Extract that .zip file and you will get directory with application name

5. Check that directory you will find app file in Payload folder, copy this app file

6. Go to ~/Library/Developer/CoreSimulator/Devices

FYI: Library folder is hidden by default in mac, you can see hidden file using below command.

defaults write com.apple.finder AppleShowAllFiles YES;
killall Finder /System/Library/CoreServices/Finder.app

Now here you'll see many directories with long hexadecimal names, these all are simulators.

To find your desired simulator, sort these directories using "Arranged By > Date Modified".

Select that simulator file and go to below location.

1. <HEXADECIMAL-SIMULATOR-STRING>/data/Containers/Bundle/Application/
2. Create new folder name with <download-app-name> and paste app file in that folder

3. Open Terminal and run below command to install this application

   xcrun simctl install booted <APP_FILE_PATH>
   

Example <APP_FILE_PATH> will be looks like below:

~/Library/Developer/CoreSimulator/Devices/<HEXADECIMAL-SIMULATOR-STRING>/data/Containers/Bundle/Application/<APP_NAME>

Try this: It will open the default mail directly.

<a href="mailto:[email protected]"><img src="ICON2.png"></a>

You have to rely on '#' but to make the task easier in vi you can perform the following (press escape first):

:10,20 s/^/#

with 10 and 20 being the start and end line numbers of the lines you want to comment out

and to undo when you are complete:

:10,20 s/^#//

If you're using a real device, you've simply run out of internal memory. Just go to Android settings -> Applications, and move some apps to the SD card or uninstall some apps.

If you're using the emulator, see RacZo's answer.

This cannot be done with the native javascript dialog box, but a lot of javascript libraries include more flexible dialogs. You can use something like jQuery UI's dialog box for this.

You'll want to register yourself for the 2 keyboard notifications:

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardDidShow:) name: UIKeyboardDidShowNotification object:nil];
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector (keyboardDidHide:) name: UIKeyboardDidHideNotification object:nil];

Great post on how to adjust your TextField to the keyboard - http://iosdevelopertips.com/user-interface/adjust-textfield-hidden-by-keyboard.html

Instead of using HibernateUtil.java, to create sessionfactory object, you should use this:

SessionFactory sessionFactory=new AnnotationConfiguration().configure().buildSessionFactory();

Because in order to avoid the exception, you'll have to declare the class object in HibernateUtil.java file as configuration.addAnnotatedClass(Student_Info.class); which looks dumb because we have provided the entry already in hibernate.cfg.xml file.

To use the AnnotationConfiguration class you'll have to add a jar to your project build path: http://www.java2s.com/Code/Jar/h/Downloadhibernate353jar.htm

I have encountered the same problem while my first Spring boot application.

In tutorial i could see following dependency to start sample application

• Spring Boot 1.4.2.RELEASE
• Maven 3
• java 8

I have done the same, my Spring STS is recognizing all class but when i am annotating my main class with @SpringBootApplication it's not recognizing this class whereas i could see jar was available in the class path.

I have following to resolve issues

• Replaced my Spring Boot 1.4.2.RELEASE to 1.5.3.RELEASE
• Right click on project and -> Maven-> Download Resources
• right click on project -> Maven-> Update project

After that it worked.

Thanks

You should be evaluating against the checked property of the checkbox element.

for (i=0; i<arrChecks.length; i++)
{
    var attribute = arrChecks[i].getAttribute("xid")
    if (attribute == elementName)
    {
        // if the current state is checked, unchecked and vice-versa
        if (arrChecks[i].checked)
        {
            arrChecks[i].checked = false;
        } else {
            arrChecks[i].checked = true;
        }

    } else {
        arrChecks[i].checked = false;
    }
}

I was running into the same problem, here is how I got it working..

open terminal:

mkdir testExpress
cd testExpress
npm install request

or

sudo npm install -g request // If you would like to globally install.

now don't use

node app.js or node test.js, you will run into this problem doing so. You can also print the problem that is being cause by using this command.. "node -p app.js"

The above command to start nodeJs has been deprecated. Instead use

npm start

You should see this..

[email protected] start /Users/{username}/testExpress
node ./bin/www

Open your web browser and check for localhost:3000

You should see Express install (Welcome to Express)

This is expected. Refer to Javadocs for split.

Splits this string around matches of the given regular expression.

This method works as if by invoking the two-argument split(java.lang.String,int) method with the given expression and a limit argument of zero. Trailing empty strings are therefore not included in the resulting array.

To do TDD many times I've used 'friend' keyword in C++.

Can a friend know everything about me?

Updated: I found this valuable answer about "friend" keyword from Bjarne Stroustrup site.

"Friend" is an explicit mechanism for granting access, just like membership.

I'm not sure that you want to send two SELECT statements in one request statement because you may not be able to access both ResultSets. The database may only return the last result set.

Multiple ResultSets

However, if you're calling a stored procedure that you know can return multiple resultsets something like this will work

CallableStatement stmt = con.prepareCall(...);
try {
...

boolean results = stmt.execute();

while (results) {
    ResultSet rs = stmt.getResultSet();
    try {
    while (rs.next()) {
        // read the data
    }
    } finally {
        try { rs.close(); } catch (Throwable ignore) {}
    }

    // are there anymore result sets?
    results = stmt.getMoreResults();
}
} finally {
    try { stmt.close(); } catch (Throwable ignore) {}
}

Multiple SQL Statements

If you're talking about multiple SQL statements and only one SELECT then your database should be able to support the one String of SQL. For example I have used something like this on Sybase

StringBuffer sql = new StringBuffer( "SET rowcount 100" );
sql.append( " SELECT * FROM tbl_books ..." );
sql.append( " SET rowcount 0" );

stmt = conn.prepareStatement( sql.toString() );

This will depend on the syntax supported by your database. In this example note the addtional spaces padding the statements so that there is white space between the staments.

Well, it's co.lemonlabs, you have a typo in your build.gradle:

compile 'co.lemonlabs:expandable-button-menu:1.0.0'

If you want to check the type of input within form, use the following code:

<script>
    function getFind(obj) {
    for (i = 0; i < obj.childNodes.length; i++) {
        if (obj.childNodes[i].tagName == "INPUT") {
            if (obj.childNodes[i].type == "text") {
                alert("this is Text Box.")
            }
            if (obj.childNodes[i].type == "checkbox") {
                alert("this is CheckBox.")
            }
            if (obj.childNodes[i].type == "radio") {
                alert("this is Radio.")
            }
        }
        if (obj.childNodes[i].tagName == "SELECT") {
            alert("this is Select")
        }
    }
}
</script>     

<script>    
    getFind(document.myform);  
</script>

In Spring every request will go through the DispatcherServlet. To avoid Static file request through DispatcherServlet(Front contoller) we configure MVC Static content.

Spring 3.1. introduced the ResourceHandlerRegistry to configure ResourceHttpRequestHandlers for serving static resources from the classpath, the WAR, or the file system. We can configure the ResourceHandlerRegistry programmatically inside our web context configuration class.

• we have added the /js/** pattern to the ResourceHandler, lets include the foo.js resource located in the webapp/js/ directory
• we have added the /resources/static/** pattern to the ResourceHandler, lets include the foo.html resource located in the webapp/resources/ directory

@Configuration
@EnableWebMvc
public class StaticResourceConfiguration implements WebMvcConfigurer {

    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        System.out.println("WebMvcConfigurer - addResourceHandlers() function get loaded...");
        registry.addResourceHandler("/resources/static/**")
                .addResourceLocations("/resources/");

        registry
            .addResourceHandler("/js/**")
            .addResourceLocations("/js/")
            .setCachePeriod(3600)
            .resourceChain(true)
            .addResolver(new GzipResourceResolver())
            .addResolver(new PathResourceResolver());
    }
}

XML Configuration

<mvc:annotation-driven />
  <mvc:resources mapping="/staticFiles/path/**" location="/staticFilesFolder/js/"
                 cache-period="60"/>

Spring Boot MVC Static Content if the file is located in the WAR’s webapp/resources folder.

spring.mvc.static-path-pattern=/resources/static/**

You could use one of these for the relative path root:

ThisWorkbook.Path
App.Path

"How do I do that? I explored PHPMyAdmin, and I can't find a "change engine" functionality."

In direct response to this part of your question, you can issue an ALTER TABLE tbl engine=InnoDB; and it'll recreate the table in the proper engine.

Here's mine command for reference:

mongoexport --db AppDB --collection files --pretty --out output.json

On Windows 7 (MongoDB 3.4), one has to move the cmd to the place where mongod.exe and mongo.exe file resides => C:\MongoDB\Server\3.4\bin else it won't work saying it does not recongnize mongoexport command.

Update in July 2020:

During the last 16 months, maybe the most notable change in the React community is React hooks.

According to what I observe, in order to gain better compatibility with functional components and hooks, projects (even those large ones) would tend to use:

1. hook + async thunk (hook makes everything very flexible so you could actually place async thunk in where you want and use it as normal functions, for example, still write thunk in action.ts and then useDispatch() to trigger the thunk: https://stackoverflow.com/a/59991104/5256695),
2. useRequest,
3. GraphQL/Apollo useQuery useMutation
4. react-fetching-library
5. other popular choices of data fetching/API call libraries, tools, design patterns, etc

In comparison, redux-saga doesn't really provide significant benefit in most normal cases of API calls comparing to the above approaches for now, while increasing project complexity by introducing many saga files/generators (also because the last release v1.1.1 of redux-saga was on 18 Sep 2019, which was a long time ago).

But still, redux-saga provides some unique features such as racing effect and parallel requests. Therefore, if you need these special functionalities, redux-saga is still a good choice.

Original post in March 2019:

Just some personal experience:

1. For coding style and readability, one of the most significant advantages of using redux-saga in the past is to avoid callback hell in redux-thunk — one does not need to use many nesting then/catch anymore. But now with the popularity of async/await thunk, one could also write async code in sync style when using redux-thunk, which may be regarded as an improvement in redux-thunk.

2. One may need to write much more boilerplate codes when using redux-saga, especially in Typescript. For example, if one wants to implement a fetch async function, the data and error handling could be directly performed in one thunk unit in action.js with one single FETCH action. But in redux-saga, one may need to define FETCH_START, FETCH_SUCCESS and FETCH_FAILURE actions and all their related type-checks, because one of the features in redux-saga is to use this kind of rich “token” mechanism to create effects and instruct redux store for easy testing. Of course one could write a saga without using these actions, but that would make it similar to a thunk.

3. In terms of the file structure, redux-saga seems to be more explicit in many cases. One could easily find an async related code in every sagas.ts, but in redux-thunk, one would need to see it in actions.

4. Easy testing may be another weighted feature in redux-saga. This is truly convenient. But one thing that needs to be clarified is that redux-saga “call” test would not perform actual API call in testing, thus one would need to specify the sample result for the steps which may be used after the API call. Therefore before writing in redux-saga, it would be better to plan a saga and its corresponding sagas.spec.ts in detail.

5. Redux-saga also provides many advanced features such as running tasks in parallel, concurrency helpers like takeLatest/takeEvery, fork/spawn, which are far more powerful than thunks.

In conclusion, personally, I would like to say: in many normal cases and small to medium size apps, go with async/await style redux-thunk. It would save you many boilerplate codes/actions/typedefs, and you would not need to switch around many different sagas.ts and maintain a specific sagas tree. But if you are developing a large app with much complex async logic and the need for features like concurrency/parallel pattern, or have a high demand for testing and maintenance (especially in test-driven development), redux-sagas would possibly save your life.

Anyway, redux-saga is not more difficult and complex than redux itself, and it does not have a so-called steep learning curve because it has well-limited core concepts and APIs. Spending a small amount of time learning redux-saga may benefit yourself one day in the future.

This coffeescript works for me with Node - the trick is that the _id get's stripped of its ObjectID wrapper when sent and returned from the client and so this needs to be replaced for updates (when no _id is provided, save will revert to insert and add one).

app.post '/new', (req, res) ->
    # post data becomes .query
    data = req.query
    coll = db.collection 'restos'
    data._id = ObjectID(data._id) if data._id

    coll.save data, {safe:true}, (err, result) ->
        console.log("error: "+err) if err
        return res.send 500, err if err

        console.log(result)
        return res.send 200, JSON.stringify result

After trying many of the above solutions with no fix, it came down to making sure 'Auto-generate binding redirects' was turned on within your application in Visual Studio.

From the terminal run

jupyter nbconvert --execute --to notebook --inplace --allow-errors --ExecutePreprocessor.timeout=-1 my_nb.ipynb

The default timeout is 30 seconds. -1 removes the restriction.

If you wish to save the output notebook to a new notebook you can use the flag --output my_new_nb.ipynb

Assuming the class name is Book:

return (Number) session.createCriteria("Book")

It is at least a Number, most likely a Long.

Wow, this had me tearing my hair out, banging my head against walls, tables and other things. I had the same or a similar issue as the OP where it was either missing / not downloading the jar files or downloading them, but not including them in the Maven dependencies with the same error message. My limited knowledge of java packaging and maven probably didn't help.

For me the problem seems to have been caused by the Dependency Type "bundle" (but I don't know how or why). I was using the Add Dependency dialog in Eclipse Mars on the pom.xml, which allows you to search and browse the central repository. I was searching and adding a dependency to jackson-core libraries, picking the latest version, available as a bundle. This kept failing.

So finally, I changed the dependency properties form bundle to jar (again using the dependency properties window), which finally downloaded and referenced the dependencies properly after saving the changes.

That approach will be good if the date-time in question is in UTC, or represents local time in an area that has never observed daylight saving time. The DateTime difference routines do not take into account Daylight Saving Time, and consequently will regard midnight June 1 as being a multiple of 24 hours after midnight January 1. I'm unaware of anything in Windows that reports historical daylight-saving rules for the current locale, so I don't think there's any good way to correctly handle any time prior to the most recent daylight-saving rule change.

The first part is for setting cron job and the next part to call your function.

To use the hex encoding in Python 3, use

>>> import codecs
>>> codecs.encode(b"c", "hex")
b'63'

In legacy Python, there are several other ways of doing this:

>>> hex(ord("c"))
'0x63'
>>> format(ord("c"), "x")
'63'
>>> "c".encode("hex")
'63'

There's no need to manually set the colors. Instead, specify a grayscale colormap...

import numpy as np
import matplotlib.pyplot as plt

# Generate data...
x = np.random.random(10)
y = np.random.random(10)

# Plot...
plt.scatter(x, y, c=y, s=500)
plt.gray()

plt.show()

Or, if you'd prefer a wider range of colormaps, you can also specify the cmap kwarg to scatter. To use the reversed version of any of these, just specify the "_r" version of any of them. E.g. gray_r instead of gray. There are several different grayscale colormaps pre-made (e.g. gray, gist_yarg, binary, etc).

import matplotlib.pyplot as plt
import numpy as np

# Generate data...
x = np.random.random(10)
y = np.random.random(10)

plt.scatter(x, y, c=y, s=500, cmap='gray')
plt.show()

I would like to suggest simppl as an option for consideration. It is a module that is available via pypi: pip install simppl and was runs on python3.

simppl allows the user to run shell commands and read the output from the screen.

The developers suggest three types of use cases:

1. The simplest usage will look like this:

    from simppl.simple_pipeline import SimplePipeline
    sp = SimplePipeline(start=0, end=100):
    sp.print_and_run('<YOUR_FIRST_OS_COMMAND>')
    sp.print_and_run('<YOUR_SECOND_OS_COMMAND>') ```

2. To run multiple commands concurrently use:

    commands = ['<YOUR_FIRST_OS_COMMAND>', '<YOUR_SECOND_OS_COMMAND>']
    max_number_of_processes = 4
    sp.run_parallel(commands, max_number_of_processes) ```

3. Finally, if your project uses the cli module, you can run directly another command_line_tool as part of a pipeline. The other tool will be run from the same process, but it will appear from the logs as another command in the pipeline. This enables smoother debugging and refactoring of tools calling other tools.

    from example_module import example_tool
    sp.print_and_run_clt(example_tool.run, ['first_number', 'second_nmber'], 
                                 {'-key1': 'val1', '-key2': 'val2'},
                                 {'--flag'}) ```

Note that the printing to STDOUT/STDERR is via python's logging module.

Here is a complete code to show how simppl works:

import logging
from logging.config import dictConfig

logging_config = dict(
    version = 1,
    formatters = {
        'f': {'format':
              '%(asctime)s %(name)-12s %(levelname)-8s %(message)s'}
        },
    handlers = {
        'h': {'class': 'logging.StreamHandler',
              'formatter': 'f',
              'level': logging.DEBUG}
        },
    root = {
        'handlers': ['h'],
        'level': logging.DEBUG,
        },
)
dictConfig(logging_config)

from simppl.simple_pipeline import SimplePipeline
sp = SimplePipeline(0, 100)
sp.print_and_run('ls')

I would say that it's preferable to use as few special characters as possible in REST URLs. One of the benefits of REST is that it makes the "interface" for a service easy to read. Camel case or Pascal case is probably good for the resource names (Users or users). I don't think there are really any hard standards around REST.

Also, I think Gandalf is right, it's usually cleaner in REST to not use query string parameters, but instead create paths that define which resources you want to deal with.

It won't let you map back onto Product since that is your table you are querying. You need an anonymous function, then you can add it to a ViewModel, and add each ViewModel to a List<MyViewModel> and return these. It's a slight digression, but I include caveats about handling nullable dates because these are a pain in the behind to deal with, just in case you have any. This is how I handled it.

Hopefully you have a ProductViewModel:

public class ProductViewModel
{
    [Key]
    public string ID { get; set; }
    public string Name { get; set; }
}

I have dependency injection/repository framework where I call a function to grab my data. Using your post as an example, in your Controller function call, it would look like this:

int categoryID = 1;
var prods = repository.GetProducts(categoryID);

In the repository class:

public IEnumerable<ProductViewModel> GetProducts(int categoryID)
{
   List<ProductViewModel> lstPVM = new List<ProductViewModel>();

   var anonymousObjResult = from p in db.Products
                            where p.CategoryID == categoryID 
                            select new
                            {
                                CatID = p.CategoryID,
                                Name = p.Name
                            };

        // NOTE: If you have any dates that are nullable and null, you'll need to
        // take care of that:  ClosedDate = (DateTime?)p.ClosedDate ?? DateTime.Now

        // If you want a particular date, you have to define a DateTime variable,
        // assign your value to it, then replace DateTime.Now with that variable. You
        // cannot call a DateTime.Parse there, unfortunately. 
        // Using 
        //    new Date("1","1","1800"); 
        // works, though. (I add a particular date so I can edit it out later.)

        // I do this foreach below so I can return a List<ProductViewModel>. 
        // You could do: return anonymousObjResult.ToList(); here
        // but it's not as clean and is an anonymous type instead of defined
        // by a ViewModel where you can control the individual field types

        foreach (var a in anonymousObjResult)
        {                
            ProductViewModel pvm = new ProductViewModel();
            pvm.ID = a.CatID;  
            pvm.Name = a.Name;
            lstPVM.Add(rvm);
        }

        // Obviously you will just have ONE item there, but I built it 
        // like this so you could bring back the whole table, if you wanted
        // to remove your Where clause, above.

        return lstPVM;
    }

Back in the controller, you do:

 List<ProductViewModel> lstProd = new List<ProductViewModel>();

 if (prods != null) 
 {
    // For setting the dates back to nulls, I'm looking for this value:
    // DateTime stdDate = DateTime.Parse("01/01/1800");

    foreach (var a in prods)
    {
        ProductViewModel o_prod = new ReportViewModel();
        o_prod.ID = a.ID;
        o_prod.Name = a.Name;
       // o_prod.ClosedDate = a.ClosedDate == stdDate ? null : a.ClosedDate;
        lstProd.Add(o_prod);
    }
}
return View(lstProd);  // use this in your View as:   @model IEnumerable<ProductViewModel>

I mean a prompt script would work if the variable was not needed for the HTML aspect, even then in certain situations, a function could be used.

var save_user_input = prompt('what needs to be saved?');
//^ makes a variable of the prompt's answer
if (save_user_input == null) {
//^ if the answer is null, it is nothing
//however, if it is nothing, it is cancelled (as seen below). If it is "null" it is what the user said, then assigned to the variable(i think), but also null as in nothing in the prompt answer window, but ok pressed. So you cant do an or "null" (which would look like: if (save_user_input == null || "null") {)because (I also don't really know if this is right) the variable is "null". Very confusing
alert("cancelled");
//^ alerts the user the cancel button was pressed. No long explanation this time.
}
//^ is an end for the if (i got stumped as to why it wasn’t working and then realised this. very important to remember.)
else {
alert(save_user_input + " is what you said");
//^ alerts the user the variable and adds the string " is what you said" on the end
}

Here comes the improved and recursive version of AgileJon's solution (demo):

function loopThrough(obj){
  for(var key in obj){
    // skip loop if the property is from prototype
    if(!obj.hasOwnProperty(key)) continue;

    if(typeof obj[key] !== 'object'){
      //your code
      console.log(key+" = "+obj[key]);
    } else {
      loopThrough(obj[key]);
    }
  }
}
loopThrough(validation_messages);

This solution works for all kinds of different depths.

Based on your question, I think that you may be a bit confused about the difference between a User and a Login. A Login is an account on the SQL Server as a whole - someone who is able to log in to the server and who has a password. A User is a Login with access to a specific database.

Creating a Login is easy and must (obviously) be done before creating a User account for the login in a specific database:

CREATE LOGIN NewAdminName WITH PASSWORD = 'ABCD'
GO

Here is how you create a User with db_owner privileges using the Login you just declared:

Use YourDatabase;
GO

IF NOT EXISTS (SELECT * FROM sys.database_principals WHERE name = N'NewAdminName')
BEGIN
    CREATE USER [NewAdminName] FOR LOGIN [NewAdminName]
    EXEC sp_addrolemember N'db_owner', N'NewAdminName'
END;
GO

Now, Logins are a bit more fluid than I make it seem above. For example, a Login account is automatically created (in most SQL Server installations) for the Windows Administrator account when the database is installed. In most situations, I just use that when I am administering a database (it has all privileges).

However, if you are going to be accessing the SQL Server from an application, then you will want to set the server up for "Mixed Mode" (both Windows and SQL logins) and create a Login as shown above. You'll then "GRANT" priviliges to that SQL Login based on what is needed for your app. See here for more information.

UPDATE: Aaron points out the use of the sp_addsrvrolemember to assign a prepared role to your login account. This is a good idea - faster and easier than manually granting privileges. If you google it you'll see plenty of links. However, you must still understand the distinction between a login and a user.

If you are using MYSQL-WORKBENCH, then you can select blob column normally and right click on column and click open value in editor. refer screenshot:

if {le_gur_bond.gur1}="" or IsNull({le_gur_bond.gur1})   Then
    ""
else 
 "and " + {le_gur_bond.gur2} + " of "+ {le_gur_bond.grr_2_address2}

I had the same problem while installing ionic@beta. I tried the following items and they didn't help me.

1. npm cache clean
2. Manually delete cache from %temp%\npm-*
3. Command prompt "Run As Administrator"

I solved the problem by installing node-v5.10.1-x64.msi (Previous version was node-v5.9.0-x64.msi) and run an npm cache clean before installing ionic@beta

It worked!

You can invoke lambda function directly (at least via Java) by using AWSLambdaClient as described in the AWS' blog post.

I got the similar error when install bundle

sudo apt-get install ruby-dev

Works great for me and solve the problem Mint 16 ruby1.9.3

You need to compile the bibtex file.

Suppose you have article.tex and article.bib. You need to run:

• latex article.tex (this will generate a document with question marks in place of unknown references)
• bibtex article (this will parse all the .bib files that were included in the article and generate metainformation regarding references)
• latex article.tex (this will generate document with all the references in the correct places)
• latex article.tex (just in case if adding references broke page numbering somewhere)

Assuming, we want to get image dimensions of <img id="an-img" src"...">

// Query after all the elements on the page have loaded.
// Or, use `onload` on a particular element to check if it is loaded.
document.addEventListener('DOMContentLoaded', function () {
  var el = document.getElementById("an-img");

  console.log({
    "naturalWidth": el.naturalWidth, // Only on HTMLImageElement
    "naturalHeight": el.naturalHeight, // Only on HTMLImageElement
    "offsetWidth": el.offsetWidth,
    "offsetHeight": el.offsetHeight
  });

Natural Dimensions

el.naturalWidth and el.naturalHeight will get us the natural dimensions, the dimensions of the image file.

Layout Dimensions

el.offsetWidth and el.offsetHeight will get us the dimensions at which the element is rendered on the document.

BernardSaucier has already given you an answer. My post is not an answer but an explanation as to why you shouldn't be using UsedRange.

UsedRange is highly unreliable as shown HERE

To find the last column which has data, use .Find and then subtract from it.

With Sheets("Sheet1")
    If Application.WorksheetFunction.CountA(.Cells) <> 0 Then
        lastCol = .Cells.Find(What:="*", _
                      After:=.Range("A1"), _
                      Lookat:=xlPart, _
                      LookIn:=xlFormulas, _
                      SearchOrder:=xlByColumns, _
                      SearchDirection:=xlPrevious, _
                      MatchCase:=False).Column
    Else
        lastCol = 1
    End If
End With

If lastCol > 8 Then
    'Debug.Print ActiveSheet.UsedRange.Columns.Count - 8

    'The above becomes

    Debug.Print lastCol - 8
End If

Motif: *args and **kwargs serves as a placeholder for the arguments that need to be passed to a function call

using *args and **kwargs to call a function

def args_kwargs_test(arg1, arg2, arg3):
    print "arg1:", arg1
    print "arg2:", arg2
    print "arg3:", arg3

Now we'll use *args to call the above defined function

#args can either be a "list" or "tuple"
>>> args = ("two", 3, 5)  
>>> args_kwargs_test(*args)

result:

arg1: two
arg2: 3
arg3: 5

Now, using **kwargs to call the same function

#keyword argument "kwargs" has to be a dictionary
>>> kwargs = {"arg3":3, "arg2":'two', "arg1":5}
>>> args_kwargs_test(**kwargs)

result:

arg1: 5
arg2: two
arg3: 3

Bottomline : *args has no intelligence, it simply interpolates the passed args to the parameters(in left-to-right order) while **kwargs behaves intelligently by placing the appropriate value @ the required place

The Apache filter is built for iterating files in a known directory. To allow wildcards in the directory also, you would have to split the path on '\' or '/' and do a filter on each part separately.

For me, parameter (JSONObject inputJsonObj) was not working. I am using jersey 2.* Hence I feel this is the

java(Jax-rs) and Angular way

@POST
@Consumes(MediaType.TEXT_PLAIN)
@Produces(MediaType.APPLICATION_JSON)
public Map<String, String> methodName(String data) throws Exception {
    JSONObject recoData = new JSONObject(data);
    //Do whatever with json object
}

Client side I used AngularJS

factory.update = function () {
data = {user:'Shreedhar Bhat',address:[{houseNo:105},{city:'Bengaluru'}]};
        data= JSON.stringify(data);//Convert object to string
        var d = $q.defer();
        $http({
            method: 'POST',
            url: 'REST/webApp/update',
            headers: {'Content-Type': 'text/plain'},
            data:data
        })
        .success(function (response) {
            d.resolve(response);
        })
        .error(function (response) {
            d.reject(response);
        });

        return d.promise;
    };

UPDATE: As the behaviour of spring.config.location now overrides the default instead of adding to it. You need to use spring.config.additional-location to keep the defaults. This is a change in behaviour from 1.x to 2.x

When using Spring Boot the properties are loaded in the following order (see Externalized Configuration in the Spring Boot reference guide).

1. Command line arguments.
2. Java System properties (System.getProperties()).
3. OS environment variables.
4. JNDI attributes from java:comp/env
5. A RandomValuePropertySource that only has properties in random.*.
6. Application properties outside of your packaged jar (application.properties including YAML and profile variants).
7. Application properties packaged inside your jar (application.properties including YAML and profile variants).
8. @PropertySource annotations on your @Configuration classes.
9. Default properties (specified using SpringApplication.setDefaultProperties).

When resolving properties (i.e. @Value("${myprop}") resolving is done in the reverse order (so starting with 9).

To add different files you can use the spring.config.location properties which takes a comma separated list of property files or file location (directories).

-Dspring.config.location=your/config/dir/

The one above will add a directory which will be consulted for application.properties files.

-Dspring.config.location=classpath:job1.properties,classpath:job2.properties

This will add the 2 properties file to the files that are loaded.

The default configuration files and locations are loaded before the additonally specified spring.config.location ones meaning that the latter will always override properties set in the earlier ones. (See also this section of the Spring Boot Reference Guide).

If spring.config.location contains directories (as opposed to files) they should end in / (and will be appended with the names generated from spring.config.name before being loaded). The default search path classpath:,classpath:/config,file:,file:config/ is always used, irrespective of the value of spring.config.location. In that way you can set up default values for your application in application.properties (or whatever other basename you choose with spring.config.name) and override it at runtime with a different file, keeping the defaults.

And on my Windows 7 machine it is here:

C:\Program Files (x86)\Microsoft SDKs\Windows\v8.1A\bin\NETFX 4.5.1 Tools

Note that the file wsdl.exe is portable, in that you can copy it to another windows machine and it works. I have not tried to see if the 4.5 exe will work on a machine that only have .NET 2.0, but this would be interesting to know.

We had this error on Oracle RAC 11g on Windows, and the solution was to create the same OS directory tree and external file on both nodes.

• The first danger lies in reload(sys).

  When you reload a module, you actually get two copies of the module in your runtime. The old module is a Python object like everything else, and stays alive as long as there are references to it. So, half of the objects will be pointing to the old module, and half to the new one. When you make some change, you will never see it coming when some random object doesn't see the change:

  (This is IPython shell)
  
  In [1]: import sys
  
  In [2]: sys.stdout
  Out[2]: <colorama.ansitowin32.StreamWrapper at 0x3a2aac8>
  
  In [3]: reload(sys)
  <module 'sys' (built-in)>
  
  In [4]: sys.stdout
  Out[4]: <open file '<stdout>', mode 'w' at 0x00000000022E20C0>
  
  In [11]: import IPython.terminal
  
  In [14]: IPython.terminal.interactiveshell.sys.stdout
  Out[14]: <colorama.ansitowin32.StreamWrapper at 0x3a9aac8>
  

• Now, sys.setdefaultencoding() proper

  All that it affects is implicit conversion str<->unicode. Now, utf-8 is the sanest encoding on the planet (backward-compatible with ASCII and all), the conversion now "just works", what could possibly go wrong?

  Well, anything. And that is the danger.

  • There may be some code that relies on the UnicodeError being thrown for non-ASCII input, or does the transcoding with an error handler, which now produces an unexpected result. And since all code is tested with the default setting, you're strictly on "unsupported" territory here, and no-one gives you guarantees about how their code will behave.
  • The transcoding may produce unexpected or unusable results if not everything on the system uses UTF-8 because Python 2 actually has multiple independent "default string encodings". (Remember, a program must work for the customer, on the customer's equipment.)
    • Again, the worst thing is you will never know that because the conversion is implicit -- you don't really know when and where it happens. (Python Zen, koan 2 ahoy!) You will never know why (and if) your code works on one system and breaks on another. (Or better yet, works in IDE and breaks in console.)

Alot of these answers are shocking, really. Heres some code from my XanderUI Control library that fixes this.

private void OnChanged(object sender, FilesystemEventArgs e)
{
    if (FSWatcher.IncludeSubdirectories == true)
    {
        if (File.Exists(e.FullPath)) { DO YOUR FILE CHANGE STUFF HERE... }
    }
    else DO YOUR DIRECTORY CHANGE STUFF HERE...
}

Sort a two dimensional array based on one column
The first column is a date of format "yyyy.MM.dd HH:mm" and the second column is a String.

Since you say 2-D array, I assume "date of format ..." means a String. Here's code for sorting a 2-D array of String[][]:

import java.util.Arrays;
import java.util.Comparator;

public class Asdf {

    public static void main(final String[] args) {
        final String[][] data = new String[][] {
                new String[] { "2009.07.25 20:24", "Message A" },
                new String[] { "2009.07.25 20:17", "Message G" },
                new String[] { "2009.07.25 20:25", "Message B" },
                new String[] { "2009.07.25 20:30", "Message D" },
                new String[] { "2009.07.25 20:01", "Message F" },
                new String[] { "2009.07.25 21:08", "Message E" },
                new String[] { "2009.07.25 19:54", "Message R" } };

        Arrays.sort(data, new Comparator<String[]>() {
            @Override
            public int compare(final String[] entry1, final String[] entry2) {
                final String time1 = entry1[0];
                final String time2 = entry2[0];
                return time1.compareTo(time2);
            }
        });

        for (final String[] s : data) {
            System.out.println(s[0] + " " + s[1]);
        }
    }

}

Output:

2009.07.25 19:54 Message R
2009.07.25 20:01 Message F
2009.07.25 20:17 Message G
2009.07.25 20:24 Message A
2009.07.25 20:25 Message B
2009.07.25 20:30 Message D
2009.07.25 21:08 Message E

Its not possible thats the whole point of hashing. You can however bruteforce by going through all possibilities (using all possible digits characters in every possible order) and hashing them and checking for a collision.

for more information on hashing and MD5 etc see: http://en.wikipedia.org/wiki/MD5 , http://en.wikipedia.org/wiki/Hash_function , http://en.wikipedia.org/wiki/Cryptographic_hash_function and http://onin.com/hhh/hhhexpl.html

I myself created my own app to do this, its open source you can check the link: http://sourceforge.net/projects/jpassrecovery/ and of course the source. Here is the source for easy access it has a basic implementation in the comments:

You shouldn't edit any code manually jetify should do this job for you, if you are running/building from cli using react-native you dont' need to do anything but if you are running/building Andriod studio you need to run jetify as pre-build, here is how can you automate this:

1- From the above menu go to edit configurations:

2- Add the bottom of the screen you will find before launch click on the plus and choose Run External Tool

2- Fill the following information, note that the working directory is your project root directory (not the android directory):

3- Make sure this run before anything else, in the end, your configuration should look something like this:

You could also use PyAutoGui to send a virtual key presses.

Here's the documentation: https://pyautogui.readthedocs.org/en/latest/

import pyautogui


pyautogui.press('Any key combination')

You can also send keys like the shift key or enter key with:

import pyautogui

pyautogui.press('shift')

Pyautogui can also send straight text like so:

import pyautogui

pyautogui.typewrite('any text you want to type')

As for pressing the "A" key 1000 times, it would look something like this:

import pyautogui

for i in range(999):
    pyautogui.press("a")

alt-tab or other tasks that require more than one key to be pressed at the same time:

import pyautogui

# Holds down the alt key
pyautogui.keyDown("alt")

# Presses the tab key once
pyautogui.press("tab")

# Lets go of the alt key
pyautogui.keyUp("alt")

You can also use barcodefragmentlib which is an extension of zxing but provides barcode scanning as fragment library, so can be very easily integrated.

Here is the supporting documentation for usage of library

Permanent generation

request.POST is just a dictionary-like object, so just index into it with dict syntax.

Assuming your form field is fred, you could do something like this:

if 'fred' in request.POST:
    mydata = request.POST['fred']

Alternately, use a form object to deal with the POST data.

A simple way using std::next_permutation:

#include <iostream>
#include <algorithm>
#include <vector>

int main() {
    int n, r;
    std::cin >> n;
    std::cin >> r;

    std::vector<bool> v(n);
    std::fill(v.end() - r, v.end(), true);

    do {
        for (int i = 0; i < n; ++i) {
            if (v[i]) {
                std::cout << (i + 1) << " ";
            }
        }
        std::cout << "\n";
    } while (std::next_permutation(v.begin(), v.end()));
    return 0;
}

or a slight variation that outputs the results in an easier to follow order:

#include <iostream>
#include <algorithm>
#include <vector>

int main() {
   int n, r;
   std::cin >> n;
   std::cin >> r;

   std::vector<bool> v(n);
   std::fill(v.begin(), v.begin() + r, true);

   do {
       for (int i = 0; i < n; ++i) {
           if (v[i]) {
               std::cout << (i + 1) << " ";
           }
       }
       std::cout << "\n";
   } while (std::prev_permutation(v.begin(), v.end()));
   return 0;
}

A bit of explanation:

It works by creating a "selection array" (v), where we place r selectors, then we create all permutations of these selectors, and print the corresponding set member if it is selected in in the current permutation of v.

You can implement it if you note that for each level r you select a number from 1 to n.

In C++, we need to 'manually' keep the state between calls that produces results (a combination): so, we build a class that on construction initialize the state, and has a member that on each call returns the combination while there are solutions: for instance

#include <iostream>
#include <iterator>
#include <vector>
#include <cstdlib>

using namespace std;

struct combinations
{
    typedef vector<int> combination_t;

    // initialize status
   combinations(int N, int R) :
       completed(N < 1 || R > N),
       generated(0),
       N(N), R(R)
   {
       for (int c = 1; c <= R; ++c)
           curr.push_back(c);
   }

   // true while there are more solutions
   bool completed;

   // count how many generated
   int generated;

   // get current and compute next combination
   combination_t next()
   {
       combination_t ret = curr;

       // find what to increment
       completed = true;
       for (int i = R - 1; i >= 0; --i)
           if (curr[i] < N - R + i + 1)
           {
               int j = curr[i] + 1;
               while (i <= R-1)
                   curr[i++] = j++;
               completed = false;
               ++generated;
               break;
           }

       return ret;
   }

private:

   int N, R;
   combination_t curr;
};

int main(int argc, char **argv)
{
    int N = argc >= 2 ? atoi(argv[1]) : 5;
    int R = argc >= 3 ? atoi(argv[2]) : 2;
    combinations cs(N, R);
    while (!cs.completed)
    {
        combinations::combination_t c = cs.next();
        copy(c.begin(), c.end(), ostream_iterator<int>(cout, ","));
        cout << endl;
    }
    return cs.generated;
}

I would second the notion that you may wish to consider a subclass instead of the approach you've outlined. However, not knowing your specific scenario, YMMV :-)

What you're thinking of is a metaclass. The __new__ function in a metaclass is passed the full proposed definition of the class, which it can then rewrite before the class is created. You can, at that time, sub out the constructor for a new one.

Example:

def substitute_init(self, id, *args, **kwargs):
    pass

class FooMeta(type):

    def __new__(cls, name, bases, attrs):
        attrs['__init__'] = substitute_init
        return super(FooMeta, cls).__new__(cls, name, bases, attrs)

class Foo(object):

Replacing the constructor is perhaps a bit dramatic, but the language does provide support for this kind of deep introspection and dynamic modification.

First of all you need to remove the data-toggle attribute. We will use some JQuery, so make sure you include it.

  <ul class='nav nav-tabs'>
    <li class='active'><a href='#home'>Home</a></li>
    <li><a href='#menu1'>Menu 1</a></li>
    <li><a href='#menu2'>Menu 2</a></li>
    <li><a href='#menu3'>Menu 3</a></li>
  </ul>

  <div class='tab-content'>
    <div id='home' class='tab-pane fade in active'>
      <h3>HOME</h3>
    <div id='menu1' class='tab-pane fade'>
      <h3>Menu 1</h3>
    </div>
    <div id='menu2' class='tab-pane fade'>
      <h3>Menu 2</h3>
    </div>
    <div id='menu3' class='tab-pane fade'>
      <h3>Menu 3</h3>
    </div>
  </div>
</div>

<script>
$(document).ready(function(){
// Handling data-toggle manually
    $('.nav-tabs a').click(function(){
        $(this).tab('show');
    });
// The on tab shown event
    $('.nav-tabs a').on('shown.bs.tab', function (e) {
        alert('Hello from the other siiiiiide!');
        var current_tab = e.target;
        var previous_tab = e.relatedTarget;
    });
});
</script>

numpy.savetxt saves an array to a text file.

import numpy
a = numpy.asarray([ [1,2,3], [4,5,6], [7,8,9] ])
numpy.savetxt("foo.csv", a, delimiter=",")

You can achieve LinearLayout cascading like this:

LinearLayout root = (LinearLayout) findViewById(R.id.my_root);    
LinearLayout llay1 = new LinearLayout(this);    
root.addView(llay1);
LinearLayout llay2 = new LinearLayout(this);    
llay1.addView(llay2);

this.props.location is a react-router feature, you'll have to install if you want to use it.

Note: doesn't return the full url.

A lot of answers above have fields compared in single comparator method which is not actually working. There are some answers though with different comparators implemented for each field, I am posting this because this example would be much more clearer and simple to understand I am believing.

class Student{
    Integer bornYear;
    Integer bornMonth;
    Integer bornDay;
    public Student(int bornYear, int bornMonth, int bornDay) {

        this.bornYear = bornYear;
        this.bornMonth = bornMonth;
        this.bornDay = bornDay;
    }
    public Student(int bornYear, int bornMonth) {

        this.bornYear = bornYear;
        this.bornMonth = bornMonth;

    }
    public Student(int bornYear) {

        this.bornYear = bornYear;

    }
    public Integer getBornYear() {
        return bornYear;
    }
    public void setBornYear(int bornYear) {
        this.bornYear = bornYear;
    }
    public Integer getBornMonth() {
        return bornMonth;
    }
    public void setBornMonth(int bornMonth) {
        this.bornMonth = bornMonth;
    }
    public Integer getBornDay() {
        return bornDay;
    }
    public void setBornDay(int bornDay) {
        this.bornDay = bornDay;
    }
    @Override
    public String toString() {
        return "Student [bornYear=" + bornYear + ", bornMonth=" + bornMonth + ", bornDay=" + bornDay + "]";
    }

@Autowired to autowire(or search) by-type
@Qualifier to autowire(or search) by-name
Other alternate option for @Qualifier is @Primary

@Component
@Qualifier("beanname")
public class A{}

public class B{

//Constructor
@Autowired  
public B(@Qualifier("beanname")A a){...} //  you need to add @autowire also 

//property
@Autowired
@Qualifier("beanname")
private A a;

}

//If you don't want to add the two annotations, we can use @Resource
public class B{

//property
@Resource(name="beanname")
private A a;

//Importing properties is very similar
@Value("${property.name}")  //@Value know how to interpret ${}
private String name;
}

more about @value

This is definitely a syntax issue, when it happened to me I discovered I typed

module.export = Component; instead of module.exports = Component;

If your object could contain any key/value pairs, you could declare an interface called keyable like :

interface keyable {
    [key: string]: any  
}

then use it as follows :

let countryProviders: keyable[];

or

let countryProviders: Array<keyable>;

In the parent table, try setting

border-collapse:separate; 
border-spacing:5em;

Plus a border declaration, and see if this achieves your desired effect. Beware, though, that IE doesn't support the "separated borders" model.

When an error occurs, the execution will continue on the next line without interrupting the script.

Try this code :

input[type="text"]{
 padding:10px 0;}

This way it remains independent of what textsize has been set for the textbox. You are increasing the height using padding instead.

In latin1 each character is exactly one byte long. In utf8 a character can consist of more than one byte. Consequently utf8 has more characters than latin1 (and the characters they do have in common aren't necessarily represented by the same byte/bytesequence).

This worked for me

If your intent is to copy the found files into /home/shantanu/tosend, you have the order of the arguments to cp reversed:

find /home/shantanu/processed/ -name '*2011*.xml' -exec cp "{}" /home/shantanu/tosend  \;

Please, note: the find command use {} as placeholder for matched file.

I achieved this via -

 <p style="display:none">{{user.role="store_user"}}</p>

$keys = array_keys($arr);
$keys = rsort($keys);

print $keys[0];

should print "10"

You want to keep the selector, so adding/removing it won't work. Instead of writing a hard and fast CSS selectors (or two), perhaps you can just use the original selector to apply new CSS rule to that element based on some criterion:

$(".test").hover(
  if(some evaluation) {
    $(this).css('border':0);
  }
);

This is a modification of nate_weldon's answer with a few improvements:

• More robust releasing of Excel objects
• Set application.DisplayAlerts = false; before attempting to save to hide prompts

Also note that the application.Workbooks.Open and ws.SaveAs methods expect sourceFilePath and targetFilePath to be full paths (ie. directory path + filename)

private static void SaveAs(string sourceFilePath, string targetFilePath)
{
    Application application = null;
    Workbook wb = null;
    Worksheet ws = null;

    try
    {
        application = new Application();
        application.DisplayAlerts = false;
        wb = application.Workbooks.Open(sourceFilePath);
        ws = (Worksheet)wb.Sheets[1];
        ws.SaveAs(targetFilePath, XlFileFormat.xlCSV);
    }
    catch (Exception e)
    {
        // Handle exception
    }
    finally
    {
        if (application != null) application.Quit();
        if (ws != null) Marshal.ReleaseComObject(ws);
        if (wb != null) Marshal.ReleaseComObject(wb);
        if (application != null) Marshal.ReleaseComObject(application);
    }
}

You need to start the SQL Server manually. Press

windows + R

type

sqlservermanager12.msc

right click ->Start

Service configuration does not display SQL Server?

The problem is that you forgot to import os. Add this line of code:

import os

And everything should be fine. Hope this helps!

If you don't care about supporting old browsers, you can use :not() to exclude that element:

.parent:hover span:not(:hover) {
    border: 10px solid red;
}

Demo: http://jsfiddle.net/vz9A9/1/

If you do want to support them, the I guess you'll have to either use JavaScript or override the CSS properties again:

.parent span:hover {
    border: 10px solid green;
}

I don't understand why no one has mentioned upgrading your graphics card... Surely if you got a high-end NVIDIA Quadro FX 4800 or something (192 CUDA cores) this would go faster...

Of course if you could afford a few NVIDIA Qadro Plex 2200 S4s (at 960 CUDA cores each), this calculation would really scream. Perhaps NVIDIA would be willing to loan you a few for a "Technology Demonstration" as a PR stunt?

Surely they'd want to be part of this historic calculation...

With this simple code:

String example="hello";

example=example.substring(0,1).toUpperCase()+example.substring(1, example.length());

System.out.println(example);

Result: Hello

EDIT: Changed the regular expression to exclude A-Z

Regular expression solution is the fastest pure python solution so far

reg=re.compile('^[a-z0-9\.]+$')
>>>reg.match('jsdlfjdsf12324..3432jsdflsdf')
True
>>> timeit.Timer("reg.match('jsdlfjdsf12324..3432jsdflsdf')", "import re; reg=re.compile('^[a-z0-9\.]+$')").timeit()
0.70509696006774902

Compared to other solutions:

>>> timeit.Timer("set('jsdlfjdsf12324..3432jsdflsdf') <= allowed", "import string; allowed = set(string.ascii_lowercase + string.digits + '.')").timeit()
3.2119350433349609
>>> timeit.Timer("all(c in allowed for c in 'jsdlfjdsf12324..3432jsdflsdf')", "import string; allowed = set(string.ascii_lowercase + string.digits + '.')").timeit()
6.7066690921783447

If you want to allow empty strings then change it to:

reg=re.compile('^[a-z0-9\.]*$')
>>>reg.match('')
False

Under request I'm going to return the other part of the answer. But please note that the following accept A-Z range.

You can use isalnum

test_str.replace('.', '').isalnum()

>>> 'test123.3'.replace('.', '').isalnum()
True
>>> 'test123-3'.replace('.', '').isalnum()
False

EDIT Using isalnum is much more efficient than the set solution

>>> timeit.Timer("'jsdlfjdsf12324..3432jsdflsdf'.replace('.', '').isalnum()").timeit()
0.63245487213134766

EDIT2 John gave an example where the above doesn't work. I changed the solution to overcome this special case by using encode

test_str.replace('.', '').encode('ascii', 'replace').isalnum()

And it is still almost 3 times faster than the set solution

timeit.Timer("u'ABC\u0131\u0661'.encode('ascii', 'replace').replace('.','').isalnum()", "import string; allowed = set(string.ascii_lowercase + string.digits + '.')").timeit()
1.5719811916351318

In my opinion using regular expressions is the best to solve this problem

It is there to specify another column as the default id column of the other table, e.g. consider the following

TableA
  id int identity
  tableb_key varchar


TableB
  id int identity
  key varchar unique

// in class for TableA
@JoinColumn(name="tableb_key", referencedColumnName="key")

Using the getBytes method, giving it the appropriate Charset (or Charset name).

Example:

String s = "Hello, there.";
byte[] b = s.getBytes(StandardCharsets.US_ASCII);

(Before Java 7: byte[] b = s.getBytes("US-ASCII");)

$ sudo rm -rf /Library/Developer/CommandLineTools
$ xcode-select --install

You were able to use the PHP Horde_Text_Diff package.

However this package is no longer available.

use "" with the string resource value.

Example :

<string>"value with spaces"</string>

OR

use \u0020 code for spaces.

Well, as most of the answers pointed out, you can include the jQuery file locally as well as use Google's CDN/Microsoft CDN servers. On choosing Google vs. Microsoft CDN go Google_CDN vs. Microsoft_CDN depending on your requirement.

Generally for intranet applications include jQuery file locally and never use the CDN method since for intranet, the LAN is 10x times faster than Internet. For Internet and public facing applications use a hybrid approach as suggested by cowgod elsewhere. Also don't forget to use the nice tool JS_Compressor to compress the extra JavaScript code you add to your jQuery library. It makes JavaScript really fast.

But, sometimes, even with user-select and touch-callout turned off, cursor: pointer; may cause this effect, so, just set cursor: default; and it'll work.

That's phpDoc syntax.

You could use the :after pseudo-selector to achieve this, though I am unsure of the backward compatibility of that selector.

body {
    background: #000000
}
body:after {
    content:'';
    position: fixed;
    height: 100%;
    width: 50%;
    left: 50%;
    background: #116699
}

I have used this to have two different gradients on a page background.

USING PHP, HTML AND JAVASCRIPT for prompting

Just if someone looking for using php, html and javascript in a single file, the answer below is working for me.. i attached with the used of bootstrap icon "trash" for the link.

<a class="btn btn-danger" href="<?php echo "delete.php?&var=$var"; ?>" onclick="return confirm('Are you sure want to delete this?');"><span class="glyphicon glyphicon-trash"></span></a>

the reason i used php code in the middle is because i cant use it from the beginning..

the code below doesnt work for me:-

echo "<a class='btn btn-danger' href='delete.php?&var=$var' onclick='return confirm('Are you sure want to delete this?');'><span class='glyphicon glyphicon-trash'></span></a>";

and i modified it as in the 1st code then i run as just what i need.. I hope that can i can help someone inneed of my case.

One more example:

If you have Column from A to D, and need to highlight the whole line (e.g. from A to D) if B is "Complete", then you can do it following:

"Custom formula is":  =$B:$B="Completed" 
Background Color:     red 
Range:                A:D

Of course, you can change Range to A:T if you have more columns.

If B contains "Complete", use search as following:

"Custom formula is":  =search("Completed",$B:$B) 
Background Color:     red 
Range:                A:D

Ganymede's version of WTP includes a revamped Javascript editor that's worth a try. The key version numbers are Eclipse 3.4 and WTP 3.0. See http://live.eclipse.org/node/569

Well a fix for you could be to put it on the UpdatedDate field and have a trigger that updates the AddedDate field with the UpdatedDate value only if AddedDate is null.

Right click on the project in which you want to put jar file. A window will open like this

Click on the AddExternal Jars there you can give the path to that jar file

-- @RowsPerPage  can be a fixed number and @PageNumber number can be passed 
DECLARE @RowsPerPage INT = 10, @PageNumber INT = 2

SELECT *

ORDER BY EmployeeNumber

OFFSET @PageNumber*@RowsPerPage ROWS

FETCH NEXT 10 ROWS ONLY

I'm no expert with DOM or Javascript/Typescript but I think that the DOM-Tags can't handle real javascript object somehow. But putting the whole object in as a string and parsing it back to an Object/JSON worked for me:

interface TestObject {
  name:string;

I found your question looking for a solution to the same problem; and what other answers fail to point is a way to use a variable to change the name of the table for every execution of your procedure in a permanent form, not temporary.

So far what I do is concatenate the entire SQL code with the variables to use. Like this:

declare @table_name as varchar(30)
select @table_name = CONVERT(varchar(30), getdate(), 112)
set @table_name = 'DAILY_SNAPSHOT_' + @table_name

EXEC('
        SELECT var1, var2, var3
        INTO '+@table_name+'
        FROM my_view
        WHERE string = ''Strings must use double apostrophe''
    ');

I hope it helps, but it could be cumbersome if the code is too large, so if you've found a better way, please share!

I also had this issue and it arose because I re-made the project and then forgot to re-link it by reference in a dependent project.

Thus it was linking by reference to the old project instead of the new one.

It is important to know that there is a bug in re-adding a previously linked project by reference. You've got to manually delete the reference in the vcxproj and only then can you re-add it. This is a known issue in Visual studio according to msdn.

Invoke mysql with the -N (the alias for -N is --skip-column-names) option:

mysql -N ...
use testdb;
select * from names;

+------+-------+
|    1 | pete  |
|    2 | john  |
|    3 | mike  |
+------+-------+
3 rows in set (0.00 sec)

Credit to ErichBSchulz for pointing out the -N alias.

To remove the grid (the vertical and horizontal lines) around the results use -s (--silent). Columns are separated with a TAB character.

mysql -s ...
use testdb;
select * from names;

id  name
1   pete
2   john
3   mike

To output the data with no headers and no grid just use both -s and -N.

mysql -sN ...

In your ipython_config.py file, search for the following lines

# c.InteractiveShellApp.matplotlib = None

and

# c.InteractiveShellApp.pylab = None

and uncomment them. Then, change None to the backend that you're using (I use 'qt4') and save the file. Restart IPython, and matplotlib and pylab should be loaded - you can use the dir() command to verify which modules are in the global namespace.

How about User-Defined Type Guards? https://www.typescriptlang.org/docs/handbook/advanced-types.html

interface Bird {
    fly();
    layEggs();
}

interface Fish {
    swim();
    layEggs();
}

function isFish(pet: Fish | Bird): pet is Fish { //magic happens here
    return (<Fish>pet).swim !== undefined;
}

// Both calls to 'swim' and 'fly' are now okay.

if (isFish(pet)) {
    pet.swim();
}
else {
    pet.fly();
}

For docker run:

Simply add the option --user <user> to change to another user when you start the docker container.

docker run -it --user nobody busybox

For docker attach or docker exec:

Since the command is used to attach/execute into the existing process, therefore it uses the current user there directly.

docker run -it busybox  # CTRL-P/Q to quit
docker attach <container id>  # then you have root user
/ # id
uid=0(root) gid=0(root) groups=10(wheel)

docker run -it --user nobody busybox # CTRL-P/Q to quit
docker attach <container id>  
/ $ id
uid=99(nobody) gid=99(nogroup)

If you really want to attach to the user you want to have, then

1. start with that user run --user <user> or mention it in your Dockerfile using USER
2. change the user using `su

if you are using netbeans you can add a jlabel to the frame and through properties change its icon to your image and remove the text. then move the jlabel to the bottom of the Jframe or any content pane through navigator

As seen in Install crontab on CentOS, the crontab package in CentOS is vixie-cron. Hence, do install it with:

yum install vixie-cron

And then start it with:

service crond start

To make it persistent, so that it starts on boot, use:

chkconfig crond on

On CentOS 7 you need to use cronie:

yum install cronie

On CentOS 6 you can install vixie-cron, but the real package is cronie:

yum install vixie-cron

and

yum install cronie

In both cases you get the same output:

In case you want to add the URL parameter in JavaScript, see this answer. As suggested there, you can use the URLSeachParams API in modern browsers as follows:

<script>
function addUrlParameter(name, value) {
  var searchParams = new URLSearchParams(window.location.search)
  searchParams.set(name, value)
  window.location.search = searchParams.toString()
}
</script>

<body>
...
  <a onclick="addUrlParameter('like', 'like')">Like this page</a>
...
</body>

I'm using Tower and for some reason my folder name was .git/refs/remotes/origin/Github. Changing it to lowercase .git/refs/remotes/origin/github solved the issue.
