There is no universally unique MVC pattern. MVC is a concept rather than a solid programming framework. You can implement your own MVC on any platform. As long as you stick to the following basic idea, you are implementing MVC:

• Model: What to render
• View: How to render
• Controller: Events, user input

Also think about it this way: When you program your model, the model should not need to worry about the rendering (or platform specific code). The model would say to the view, I don't care if your rendering is Android or iOS or Windows Phone, this is what I need you to render. The view would only handle the platform-specific rendering code.

This is particularly useful when you use Mono to share the model in order to develop cross-platform applications.

You have to use the NotifyIcon control from System.Windows.Forms, or alternatively you can use the Notify Icon API provided by Windows API. WPF Provides no such equivalent, and it has been requested on Microsoft Connect several times.

I have code on GitHub which uses System.Windows.Forms NotifyIcon Component from within a WPF application, the code can be viewed at https://github.com/wilson0x4d/Mubox/blob/master/Mubox.QuickLaunch/AppWindow.xaml.cs

Here are the summary bits:

Create a WPF Window with ShowInTaskbar=False, and which is loaded in a non-Visible State.

At class-level:

private System.Windows.Forms.NotifyIcon notifyIcon = null;

During OnInitialize():

notifyIcon = new System.Windows.Forms.NotifyIcon();
notifyIcon.Click += new EventHandler(notifyIcon_Click);
notifyIcon.DoubleClick += new EventHandler(notifyIcon_DoubleClick);
notifyIcon.Icon = IconHandles["QuickLaunch"];

During OnLoaded():

notifyIcon.Visible = true;

And for interaction (shown as notifyIcon.Click and DoubleClick above):

void notifyIcon_Click(object sender, EventArgs e)
{
    ShowQuickLaunchMenu();
}

From here you can resume the use of WPF Controls and APIs such as context menus, pop-up windows, etc.

It's that simple. You don't exactly need a WPF Window to host to the component, it's just the most convenient way to introduce one into a WPF App (as a Window is generally the default entry point defined via App.xaml), likewise, you don't need a WPF Wrapper or 3rd party control, as the SWF component is guaranteed present in any .NET Framework installation which also has WPF support since it's part of the .NET Framework (which all current and future .NET Framework versions build upon.) To date, there is no indication from Microsoft that SWF support will be dropped from the .NET Framework anytime soon.

Hope that helps.

It's a little cheese that you have to use a pre-3.0 Framework Component to get a tray-icon, but understandably as Microsoft has explained it, there is no concept of a System Tray within the scope of WPF. WPF is a presentation technology, and Notification Icons are an Operating System (not a "Presentation") concept.

static T DeserializeXml<T>(string sourceXML) where T : class
{
    var serializer = new XmlSerializer(typeof(T));
    T result = null;

    using (TextReader reader = new StringReader(sourceXML))
    {
        result = (T) serializer.Deserialize(reader);
    }

    return result;
}

Also you can add #include<vector> in the header. When two of the above solutions don't work.

Let's go to the source -- 2.6.32, for example. The message is printed by show_signal_msg() function in arch/x86/mm/fault.c if the show_unhandled_signals sysctl is set.

"error" is not an errno nor a signal number, it's a "page fault error code" -- see definition of enum x86_pf_error_code.

"[7fa44d2f8000+f6f000]" is starting address and size of virtual memory area where offending object was mapped at the time of crash. Value of "ip" should fit in this region. With this info in hand, it should be easy to find offending code in gdb.

If you are using AngularJS you need to pass the body params as string:

    factory.getToken = function(person_username) {
    console.log('Getting DI Token');
    var url = diUrl + "/token";

    return $http({
        method: 'POST',
        url: url,
        data: 'grant_type=password&[email protected]&password=mypass',
        responseType:'json',
        headers: { 'Content-Type': 'application/x-www-form-urlencoded' }
    });
};

Simply create a function like this

  function methodName(params) {
    //the thing  you wanna do
  }

and call it in the place you need

 <Icon onClick = {() => { methodName(theParamsYouwantToPass);} }/>

You do not really need NLTK to remove punctuation. You can remove it with simple python. For strings:

import string
s = '... some string with punctuation ...'
s = s.translate(None, string.punctuation)

Or for unicode:

import string
translate_table = dict((ord(char), None) for char in string.punctuation)   
s.translate(translate_table)

and then use this string in your tokenizer.

P.S. string module have some other sets of elements that can be removed (like digits).

if you give a 2D array to the plot function of matplotlib it will assume the columns to be lines:

If x and/or y is 2-dimensional, then the corresponding columns will be plotted.

In your case your shape is not accepted (100, 1, 1, 8000). As so you can using numpy squeeze to solve the problem quickly:

np.squeez doc: Remove single-dimensional entries from the shape of an array.

import numpy as np
import matplotlib.pyplot as plt

data = np.random.randint(3, 7, (10, 1, 1, 80))
newdata = np.squeeze(data) # Shape is now: (10, 80)
plt.plot(newdata) # plotting by columns
plt.show()

But notice that 100 sets of 80 000 points is a lot of data for matplotlib. I would recommend that you look for an alternative. The result of the code example (run in Jupyter) is:

In a match situation the first would return one match per whitespace, when the second would return a match for each group of whitespaces.

The result is the same because you're replacing it with an empty string. If you replace it with 'x' for instance, the results would differ.

str.replace(/\s/g, '') will return 'xxAxBxxCxxxDxEF '

while str.replace(/\s+/g, '') will return 'xAxBxCxDxEF '

because \s matches each whitespace, replacing each one with 'x', and \s+ matches groups of whitespaces, replacing multiple sequential whitespaces with a single 'x'.

use flex

.parent{
    display: flex
}

.fit-parent{
    display: flex;
    flex-grow: 1
}

I assume you're using typescript.

To be extra cautious you can define your type as an array of objects that need to match certain interface:

type MyArrayType = Array<{id: number, text: string}>;

const arr: MyArrayType = [
    {id: 1, text: 'Sentence 1'},
    {id: 2, text: 'Sentence 2'},
    {id: 3, text: 'Sentence 3'},
    {id: 4, text: 'Sentenc4 '},
];

Or short syntax without defining a custom type:

const arr: Array<{id: number, text: string}> = [...];

How about reinstalling the node module? Go to the root directory of the project and remove the current node modules and install again.

These are the commands : rm -rf node_modules npm install

OR

npm uninstall -g react-native-cli and

npm install -g react-native-cli

Port Access

Firewalls and other security tools may prevent RabbitMQ from binding to a port. When that happens, RabbitMQ will fail to start. Make sure the following ports can be opened:

4369: epmd, a peer discovery service used by RabbitMQ nodes and CLI tools

5672, 5671: used by AMQP 0-9-1 and 1.0 clients without and with TLS

25672: used by Erlang distribution for inter-node and CLI tools communication and is allocated from a dynamic range (limited to a single port by default, computed as AMQP port + 20000). See networking guide for details.

15672: HTTP API clients and rabbitmqadmin (only if the management plugin is enabled)

61613, 61614: STOMP clients without and with TLS (only if the STOMP plugin is enabled)

1883, 8883: (MQTT clients without and with TLS, if the MQTT plugin is enabled

15674: STOMP-over-WebSockets clients (only if the Web STOMP plugin is enabled)

15675: MQTT-over-WebSockets clients (only if the Web MQTT plugin is enabled)

Reference doc: https://www.rabbitmq.com/install-windows-manual.html

name ="bar"
list = [["foo", 1], ["bar", 2], ["baz", 3]]
new_list=[]
for item in list:
    new_list.append(item[0])
print(new_list)
try:
    location= new_list.index(name)
except:
    location=-1
print (location)

This accounts for if the string is not in the list too, if it isn't in the list then location = -1

The href value inside the base tag will become your reference point for all your relative paths and thus override your current directory path value otherwise - the '~' is the root of your site

    <head>
        <base href="~/" />
    </head>

In addition to @takemyoxygen's answer the convention of having a function name that ends in Async is that this function is truly asynchronous. I.e. it does not start a new thread and it doesn't simply call Task.Run. If that is all the code that is in your function, it will be better to remove it completely and simply have:

List<Item> list = await Task.Run(() => manager.GetList());

I got the same issue on MacOS Catalina.

I think I identified the root cause: I have switched the default Apple ID account and the new one was not activated as a Developer account. When I ran the xcode-select --install command, I got the same error as stated in the issue description.

After reading this post on stackoverflow, I went on https://developer.apple.com/downloads and I was asked to accept Developers terms. I think it enabled my account as a developer one. Then, I tried to run xcode-select --install again and it worked.

Create a file with name .env in the main directory besidespackage.json and set PORT variable to desired port number.

For example:

.env

PORT=4200

You can find the documentation for this action here: https://create-react-app.dev/docs/advanced-configuration

Array.filter( document.getElementsByClassName('appBanner'), function(elem){ elem.style.visibility = 'hidden'; });

I am using this in my code.Try this

var x=$("#checkbox").is(":checked");

If the checkbox is checked x will be true otherwise it will be false.

If you want a method like public void doSomething([Object implements Serializable]) you can just type it like this public void doSomething(Serializable serializableObject). You can now pass it any object that implements Serializable but using the serializableObject you only have access to the methods implemented in the object from the Serializable interface.

I had the URL from run time, below gave the correct answer:

let url = "www.site.com/index.php#hello";
alert(url.split('#')[1]);

hope this helps

Using refs is not best practice because it reads the DOM directly, it's better to use React's state instead. Also, your button doesn't change because the component is not re-rendered and stays in its initial state.

You can use setState together with an onChange event listener to render the component again every time the input field changes:

// Input field listens to change, updates React's state and re-renders the component.
<input onChange={e => this.setState({ value: e.target.value })} value={this.state.value} />

// Button is disabled when input state is empty.
<button disabled={!this.state.value} />

Here's a working example:

class AddItem extends React.Component {_x000D_
  constructor() {_x000D_
    super();_x000D_
    this.state = { value: '' };_x000D_

1. Before that <input type="file">, add an image and <input style="position:absolute"> it will occupy the space of <input type="file">

2. Use the following CSS to the file element

   position:relative;  
   opacity:0;  
   z-index:99;
   

I set all element's border-radius to "0" like this:

* {
  border-radius: 0 !important;
}

As I'm sure I don't want to overwrite this later I just use !important.

If you are not compiling your less files just do:

* {
  -webkit-border-radius: 0 !important;
     -moz-border-radius: 0 !important;
          border-radius: 0 !important;
}

In bootstrap 3 if you are compiling it you can now set radius in the variables.less file:

@border-radius-base:        0px;
@border-radius-large:       0px;
@border-radius-small:       0px;

In bootstrap 4 if you are compiling it you can disable radius alltogether in the _custom.scss file:

$enable-rounded:   false;

Once you have .gs and .html files in place save them and reload your spreadsheet. You will see "Custom menu" as the last item of your top menu. Select cell you would like to manage and click on this menu item.

During the first time it will ask you to authorize application - go ahead and do this.

Note (1): make sure that your cell has "Data validation" defined before you click on "Custom menu".

Note (2): it appeared that solution works with "List from a range" criteria for Data validation (it does not work with "List of items")

With reference to Cori's answer, I modified it and used below command, which is working. Without exit, remaining command was actually logging to remote machine, which I didn't want in script

ssh -o StrictHostKeyChecking=no user@ip_of_remote_machine "exit"

You can use the CONCAT function to do that:

UPDATE tbl SET col=CONCAT('test',col);

If you want to get cleverer and only update columns which don't already have test prepended, try

UPDATE tbl SET col=CONCAT('test',col)
WHERE col NOT LIKE 'test%';

Here is a read/write example. The with statements insure the close() statement will be called by the file object regardless of whether an exception is thrown. http://effbot.org/zone/python-with-statement.htm

import sys

fIn = 'symbolsIn.csv'
fOut = 'symbolsOut.csv'

try:
   with open(fIn, 'r') as f:
      file_content = f.read()
      print "read file " + fIn
   if not file_content:
      print "no data in file " + fIn
      file_content = "name,phone,address\n"
   with open(fOut, 'w') as dest:
      dest.write(file_content)
      print "wrote file " + fOut
except IOError as e:
   print "I/O error({0}): {1}".format(e.errno, e.strerror)
except: #handle other exceptions such as attribute errors
   print "Unexpected error:", sys.exc_info()[0]
print "done"

Make sure you remove any java.exe, javaw.exe and javaws.exe from your system.

• if you have an x32 system (Win XP 32 bits) Windows\System32 folder

• if you have an x64 system (Win 7 64 bits) also do the same under Windows\SysWOW64 folder

Add the outerheight to the top and you have the bottom, relative to the parent element:

var $el = $('#bottom');  //record the elem so you don't crawl the DOM everytime  
var bottom = $el.position().top + $el.outerHeight(true); // passing "true" will also include the top and bottom margin

With absolutely positioned elements or when positioning relative to the document, you will need to instead evaluate using offset:

var bottom = $el.offset().top + $el.outerHeight(true);

As pointed out by trnelson this does not work 100% of the time. To use this method for positioned elements, you also must account for offset. For an example see the following code.

var bottom = $el.position().top + $el.offset().top + $el.outerHeight(true);

Change your code into

<input class="my-style" type="text" />

CSS:

.my-style {
  font-size:25px;
}

brew help. If brew is there, you get output. If not, you get 'command not found'. If you need to check in a script, you can work out how to redirect output and check $?.

global is a bit of a misnomer in Python, module_namespace would be more descriptive.

The fully qualified name of foo is file1.foo and the global statement is best shunned as there are usually better ways to accomplish what you want to do. (I can't tell what you want to do from your toy example.)

From Python 3.10 there is a new feature of Parenthesized context managers, which permits syntax such as:

with (
    A() as a,
    B() as b
):
    do_something(a, b)

I just wrote this short script; seems to work.

/**
 * Find all the elements with a tagName that matches.
 * @param {RegExp} regEx  regular expression to match against tagName
 * @returns {Array}       elements in the DOM that match
 */
function getAllTagMatches(regEx) {
  return Array.prototype.slice.call(document.querySelectorAll('*')).filter(function (el) { 
    return el.tagName.match(regEx);
  });
}
getAllTagMatches(/^di/i); // Returns an array of all elements that begin with "di", eg "div"

(1:nrow(mydata_2))[mydata_2[,4] == 1578]

Of course there may be more than one row with a value of 1578.

You may try this method:

    private bool ValidatePassword(string password, out string ErrorMessage)
        {
            var input = password;
            ErrorMessage = string.Empty;

            if (string.IsNullOrWhiteSpace(input))
            {
                throw new Exception("Password should not be empty");
            }

            var hasNumber = new Regex(@"[0-9]+");
            var hasUpperChar = new Regex(@"[A-Z]+");
            var hasMiniMaxChars = new Regex(@".{8,15}");
            var hasLowerChar = new Regex(@"[a-z]+");
            var hasSymbols = new Regex(@"[!@#$%^&*()_+=\[{\]};:<>|./?,-]");

            if (!hasLowerChar.IsMatch(input))
            {
                ErrorMessage = "Password should contain at least one lower case letter.";
                return false;
            }
            else if (!hasUpperChar.IsMatch(input))
            {
                ErrorMessage = "Password should contain at least one upper case letter.";
                return false;
            }
            else if (!hasMiniMaxChars.IsMatch(input))
            {
                ErrorMessage = "Password should not be lesser than 8 or greater than 15 characters.";
                return false;
            }
            else if (!hasNumber.IsMatch(input))
            {
                ErrorMessage = "Password should contain at least one numeric value.";
                return false;
            }

            else if (!hasSymbols.IsMatch(input))
            {
                ErrorMessage = "Password should contain at least one special case character.";
                return false;
            }
            else
            {
                return true;
            }
        }

If you want to keep Parallelise Build enabled and avoid the missing header problems, then provide a pre-build step in your scheme to put the react headers into the derived-data area. Notice the build settings are coming from the React project in this case. Yes it's not a thing of beauty but it gets the job done and also shaves a lot of time off the builds. The prebuild step output ends up in prebuild.log. The exact headers you'll need to copy over will depend on your project react-native dependencies, but you'll get the jist from this.

Get the derived data directory from the environment variables and copy the required react headers over.

#build_prestep.sh (chmod a+x)
derived_root=$(echo $SHARED_DERIVED_FILE_DIR|sed 's/DerivedSources//1')
react_base_headers=$(echo $PROJECT_FILE_PATH|sed 's#React.xcodeproj#Base/#1')
react_view_headers=$(echo $PROJECT_FILE_PATH|sed 's#React.xcodeproj#Views/#1')
react_modules_head=$(echo $PROJECT_FILE_PATH|sed 's#React.xcodeproj#Modules/#1')
react_netw_headers=$(echo $PROJECT_FILE_PATH|sed 's#React/React.xcodeproj#Libraries/Network/#1')
react_image_header=$(echo $PROJECT_FILE_PATH|sed 's#React/React.xcodeproj#Libraries/Image/#1')

echo derived root = ${derived_root}
echo react headers = ${react_base_headers}

mkdir -p ${derived_root}include/React/

find  "${react_base_headers}" -type f -iname "*.h" -exec cp {} "${derived_root}include/React/" \;
find  "${react_view_headers}" -type f -iname "*.h" -exec cp {} "${derived_root}include/React/" \;
find  "${react_modules_head}" -type f -iname "*.h" -exec cp {} "${derived_root}include/React/" \;
find  "${react_netw_headers}" -type f -iname "*.h" -exec cp {} "${derived_root}include/React/" \;
find  "${react_image_header}" -type f -iname "*.h" -exec cp {} "${derived_root}include/React/" \;

The script does get invoked during a build-clean - which is not ideal. In my case there is one env variable which changes letting me exit the script early during a clean.

if [ "$RUN_CLANG_STATIC_ANALYZER" != "NO" ] ; then
    exit 0

Remember that union will merge results (SQL Server to be sure)(feature or bug?)

select 1 as id, 3 as value
union
select 1 as id, 3 as value

id,value

1,3

select * from (select 1 as id, 3 as value) t1 inner join (select 1 as id, 3 as value) t2 on t1.id = t2.id

id,value,id,value

1,3,1,3

Here is the complete solution

html code,

create the text anf file upload fields as shown below

    <div class="form-group">
        <div>
            <label for="usr">User Name:</label>
            <input type="text" id="usr" ng-model="model.username">
        </div>
        <div>
            <label for="pwd">Password:</label>
            <input type="password" id="pwd" ng-model="model.password">
        </div><hr>
        <div>
            <div class="col-lg-6">
                <input type="file" file-model="model.somefile"/>
            </div>


        </div>
        <div>
            <label for="dob">Dob:</label>
            <input type="date" id="dob" ng-model="model.dob">
        </div>
        <div>
            <label for="email">Email:</label>
            <input type="email"id="email" ng-model="model.email">
        </div>


        <button type="submit" ng-click="saveData(model)" >Submit</button>

directive code

create a filemodel directive to parse file

.directive('fileModel', ['$parse', function ($parse) {
return {
    restrict: 'A',
    link: function(scope, element, attrs) {
        var model = $parse(attrs.fileModel);
        var modelSetter = model.assign;

        element.bind('change', function(){
            scope.$apply(function(){
                modelSetter(scope, element[0].files[0]);
            });
        });
    }
};}]);

Service code

append the file and fields to form data and do $http.post as shown below remember to keep 'Content-Type': undefined

 .service('fileUploadService', ['$http', function ($http) {
    this.uploadFileToUrl = function(file, username, password, dob, email, uploadUrl){
        var myFormData = new FormData();

        myFormData.append('file', file);
        myFormData.append('username', username);
        myFormData.append('password', password);
        myFormData.append('dob', dob);
        myFormData.append('email', email);


        $http.post(uploadUrl, myFormData, {
            transformRequest: angular.identity,
            headers: {'Content-Type': undefined}
        })
            .success(function(){

            })
            .error(function(){
            });
    }
}]);

In controller

Now in controller call the service by sending required data to be appended in parameters,

$scope.saveData  = function(model){
    var file = model.myFile;
    var uploadUrl = "/api/createUsers";
    fileUpload.uploadFileToUrl(file, model.username, model.password, model.dob, model.email, uploadUrl);
};

ImageMagick and GD can handle PNGs too; heck, you could even do stuff with nothing but gdk-pixbuf. Are you looking for a graphical editor, or scriptable/embeddable libraries?

Updated Answer

I've noticed a lot of people are using this answer so I decided to update it a little bit. If you want to see the original answer, check below. The new answer demonstrates how you can add some style to your list.

ul > li {_x000D_
    display: inline-block;_x000D_
    /* You can also add some margins here to make it look prettier */_x000D_
    zoom:1;_x000D_
    *display:inline;_x000D_
    /* this fix is needed for IE7- */_x000D_
}

<ul>_x000D_
    <li> <a href="#">some item</a>_x000D_
_x000D_
    </li>_x000D_
    <li> <a href="#">another item</a>_x000D_
_x000D_
    </li>_x000D_
</ul>

If you want to drop a table you should execute the following query in a single step

SET FOREIGN_KEY_CHECKS=0; DROP TABLE table_name;

A2DD.h

class A2DD
{
  private:
  int gx;
  int gy;

  public:
  A2DD(int x,int y);

  int getSum();
};

A2DD.cpp

  A2DD::A2DD(int x,int y)
  {
    gx = x;
    gy = y;
  }

  int A2DD::getSum()
  {
    return gx + gy;
  }

The idea is to keep all function signatures and members in the header file.
This will allow other project files to see how the class looks like without having to know the implementation.

And besides that, you can then include other header files in the implementation instead of the header. This is important because whichever headers are included in your header file will be included (inherited) in any other file that includes your header file.

If you are still interested, Chris Wolf made a prototype implementation of SQLite with Stored Procedures. You can find the details at his blog post: Adding Stored Procedures to SQLite

Customizing CORS for Angular 5 and Spring Security (Cookie base solution)

On the Angular side required adding option flag withCredentials: true for Cookie transport:

constructor(public http: HttpClient) {
}

public get(url: string = ''): Observable<any> {
    return this.http.get(url, { withCredentials: true });
}

On Java server-side required adding CorsConfigurationSource for configuration CORS policy:

@Configuration
@EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {

    @Bean
    CorsConfigurationSource corsConfigurationSource() {
        CorsConfiguration configuration = new CorsConfiguration();
        // This Origin header you can see that in Network tab
        configuration.setAllowedOrigins(Arrays.asList("http:/url_1", "http:/url_2")); 
        configuration.setAllowedMethods(Arrays.asList("GET","POST"));
        configuration.setAllowedHeaders(Arrays.asList("content-type"));
        configuration.setAllowCredentials(true);
        UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
        source.registerCorsConfiguration("/**", configuration);
        return source;
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.cors().and()...
    }
}

Method configure(HttpSecurity http) by default will use corsConfigurationSource for http.cors()

variable declares and call like this in a class

class X {
    var x: Int = 3

}
var y = X()
print("value of x is: ", y.x)

//value of x is:  3

now you want to program to make the default value of x more than or equal to 3. Now take the hypothetical case if x is less than 3, your program will fail. so, you want people to either put 3 or more than 3. Swift got it easy for you and it is important to understand this bit-advance way of dating the variable value because they will extensively use in iOS development. Now let's see how get and set will be used here.

class X {
    var _x: Int = 3
    var x: Int {
        get {
            return _x
        }
        set(newVal) {  //set always take 1 argument
            if newVal >= 3 {
             _x = newVal //updating _x with the input value by the user
            print("new value is: ", _x)
            }
            else {
                print("error must be greater than 3")
            }
        }
    }
}
let y = X()
y.x = 1
print(y.x) //error must be greater than 3
y.x = 8 // //new value is: 8

if you still have doubts, just remember, the use of get and set is to update any variable the way we want it to be updated. get and set will give you better control to rule your logic. Powerful tool hence not easily understandable.

If you can't get text parsing to work using the accepted answer (e.g if your text file contains non uniform rows) then it's worth trying with Python's csv library - here's an example using a user defined Dialect:

 import csv

 csv.register_dialect('skip_space', skipinitialspace=True)
 with open(my_file, 'r') as f:
      reader=csv.reader(f , delimiter=' ', dialect='skip_space')
      for item in reader:
          print(item)

If you are creating many graphs, you could be tired of typing for each graph the lines of code controlling for the size of the titles and texts. What I typically do is creating an object (of class "theme" "gg") that defines the desired theme characteristics. You can do that at the beginning of your code.

My_Theme = theme(
  axis.title.x = element_text(size = 16),
  axis.text.x = element_text(size = 14),
  axis.title.y = element_text(size = 16))

Next, all you will have to do is adding My_Theme to your graphs.

g + My_Theme

g1 + My_Theme 

I provided a couple of reasonably interesting answers to this question:

Nlog - Generating Header Section for a log file

Adding a Header:

The question wanted to know how to add a header to the log file. Using config entries like this allow you to define the header format separately from the format of the rest of the log entries. Use a single logger, perhaps called "headerlogger" to log a single message at the start of the application and you get your header:

Define the header and file layouts:

  <variable name="HeaderLayout" value="This is the header.  Start time = ${longdate} Machine = ${machinename} Product version = ${gdc:item=version}"/>
  <variable name="FileLayout" value="${longdate} | ${logger} | ${level} | ${message}" />

Define the targets using the layouts:

<target name="fileHeader" xsi:type="File" fileName="xxx.log" layout="${HeaderLayout}" />
<target name="file" xsi:type="File" fileName="xxx.log" layout="${InfoLayout}" />

Define the loggers:

<rules>
  <logger name="headerlogger" minlevel="Trace" writeTo="fileHeader" final="true" />
  <logger name="*" minlevel="Trace" writeTo="file" />
</rules>

Write the header, probably early in the program:

  GlobalDiagnosticsContext.Set("version", "01.00.00.25");

  LogManager.GetLogger("headerlogger").Info("It doesn't matter what this is because the header format does not include the message, although it could");

This is largely just another version of the "Treating exceptions differently" idea.

Log each log level with a different layout

Similarly, the poster wanted to know how to change the format per logging level. It wasn't clear to me what the end goal was (and whether it could be achieved in a "better" way), but I was able to provide a configuration that did what he asked:

  <variable name="TraceLayout" value="This is a TRACE - ${longdate} | ${logger} | ${level} | ${message}"/> 
  <variable name="DebugLayout" value="This is a DEBUG - ${longdate} | ${logger} | ${level} | ${message}"/> 
  <variable name="InfoLayout" value="This is an INFO - ${longdate} | ${logger} | ${level} | ${message}"/> 
  <variable name="WarnLayout" value="This is a WARN - ${longdate} | ${logger} | ${level} | ${message}"/> 
  <variable name="ErrorLayout" value="This is an ERROR - ${longdate} | ${logger} | ${level} | ${message}"/> 
  <variable name="FatalLayout" value="This is a FATAL - ${longdate} | ${logger} | ${level} | ${message}"/> 
  <targets> 
    <target name="fileAsTrace" xsi:type="FilteringWrapper" condition="level==LogLevel.Trace"> 
      <target xsi:type="File" fileName="xxx.log" layout="${TraceLayout}" /> 
    </target> 
    <target name="fileAsDebug" xsi:type="FilteringWrapper" condition="level==LogLevel.Debug"> 
      <target xsi:type="File" fileName="xxx.log" layout="${DebugLayout}" /> 
    </target> 
    <target name="fileAsInfo" xsi:type="FilteringWrapper" condition="level==LogLevel.Info"> 
      <target xsi:type="File" fileName="xxx.log" layout="${InfoLayout}" /> 
    </target> 
    <target name="fileAsWarn" xsi:type="FilteringWrapper" condition="level==LogLevel.Warn"> 
      <target xsi:type="File" fileName="xxx.log" layout="${WarnLayout}" /> 
    </target> 
    <target name="fileAsError" xsi:type="FilteringWrapper" condition="level==LogLevel.Error"> 
      <target xsi:type="File" fileName="xxx.log" layout="${ErrorLayout}" /> 
    </target> 
    <target name="fileAsFatal" xsi:type="FilteringWrapper" condition="level==LogLevel.Fatal"> 
      <target xsi:type="File" fileName="xxx.log" layout="${FatalLayout}" /> 
    </target> 
  </targets> 


    <rules> 
      <logger name="*" minlevel="Trace" writeTo="fileAsTrace,fileAsDebug,fileAsInfo,fileAsWarn,fileAsError,fileAsFatal" /> 
      <logger name="*" minlevel="Info" writeTo="dbg" /> 
    </rules> 

Again, very similar to Treating exceptions differently.

What's about a simple writeLines()?

txt <- "Hallo\nWorld"
writeLines(txt, "outfile.txt")

or

txt <- c("Hallo", "World")
writeLines(txt, "outfile.txt")

My experience is the same as some others mentioned. The meta tag...

<meta name = "format-detection" content = "telephone=no">

...works when the website is running in Mobile Safari (i.e., with chrome) but stops working when run as a webapp (i.e., is saved to home screen and runs without chrome).

My less-than-ideal solution is to insert the values into input fields...

<input type="text" readonly="readonly" style="border:none;" value="3105551212">

It's less than ideal because, despite the border being set to none, iOS renders a multi-pixel gray bar above the field. But, it's better than seeing the number as a link.

The getDrawable (int id) method is deprecated as of API 22.

Instead you should use the getDrawable (int id, Resources.Theme theme) for API 21+

Code would look something like this.

Drawable myDrawable;
if(android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.LOLLIPOP){
    myDrawable = context.getResources().getDrawable(id, context.getTheme());
} else {
    myDrawable = context.getResources().getDrawable(id);
}

This may do the trick:

\b\p{L}*Id\b

Where \p{L} matches any (Unicode) letter and \b matches a word boundary.

Because when the script executes the browser has not yet parsed the <body>, so it does not know that there is an element with the specified id.

Try this instead:

<html>
<head>
    <title></title>
    <script type="text/javascript">
        window.onload = (function () {
            var refButton = document.getElementById("btnButton");

            refButton.onclick = function() {
                alert('Dhoor shala!');
            };
        });
    </script>
    </head>
<body>
    <form id="form1">
    <div>
        <input id="btnButton" type="button" value="Click me"/>
    </div>
</form>
</body>
</html>

Note that you may as well use addEventListener instead of window.onload = ... to make that function only execute after the whole document has been parsed.

You are looking for a simple code, like this:

    List<string> tagList = new List<string>(new[]
    {
         "A"
        ,"B"
        ,"C"
        ,"D"
        ,"E"
    });

Try this

myDataTable.Select("[Name] is NULL OR [Name] <> 'n/a'" )

Edit: Relevant sources:

• DataTable.Select Method (String)
• Expression filtering syntax

Most of previous examples will raise an exception in case your string is not long enough.

Another approach is to use 'yourstring'.ljust(100)[:100].strip().

This will give you first 100 chars. You might get a shorter string in case your string last chars are spaces.

Try this:

runas.exe /savecred /user:administrator "%sysdrive%\testScripts\testscript1.ps1" 

It saves the password the first time and never asks again. Maybe when you change the administrator password you will be prompted again.

You can try the following:

First, add async defer. This specifies that the script will be executed asynchronously as soon as it is available and when the page has finished parsing.

Second, add the initMap() function as a callback in a script tag inside your html. In this way the map will be initialized before the document.ready and window.onload:

<script async defer src="{{ 'https://maps.googleapis.com/maps/api/js?key=$key&language='.$language.'&region='.$country.'&callback=initMap' }}"></script>

<script>
    var map;
    function initMap() {
        map = new google.maps.Map(document.getElementById('map'), {
            center: {lat: -34.397, lng: 150.644},
            zoom: 4,
            disableDefaultUI: false,
            scrollwheel: false,
            styles: [{ ... }]
        });
    }
</script> 

Finally, you can use the map object inside your js files.

Now you can use Template Literals:

var w = "the Word";_x000D_
var num1 = 2;_x000D_
var num2 = 3;_x000D_
_x000D_
var long_multiline_string = `This is very long_x000D_
multiline templete string. Putting somthing here:_x000D_
${w}_x000D_
I can even use expresion interpolation:_x000D_
Two add three = ${num1 + num2}_x000D_
or use Tagged template literals_x000D_
You need to enclose string with the back-tick (\` \`)`;_x000D_
_x000D_
console.log(long_multiline_string);

text and varchar have different implicit type conversions. The biggest impact that I've noticed is handling of trailing spaces. For example ...

select ' '::char = ' '::varchar, ' '::char = ' '::text, ' '::varchar = ' '::text

returns true, false, true and not true, true, true as you might expect.

This worked for me.

onClick={() => {window.open('https://www.google.com/');}}

1. Workbenching might result some very small differences in some cases but the way of processing is browser dependent anyway so not worth bothering
2. Because of different ways of processing
3. You can't call it a browser if the behavior would be different anyhow

I had problem with encoding cyrillic letters to URF-8.

I modified one of the above scripts to match cyrillic char map. Implmented is the cyrrilic section of

https://en.wikipedia.org/wiki/UTF-8 and http://www.utf8-chartable.de/unicode-utf8-table.pl?start=1024

If you want your container to have it's own virtual ethernet socket (with it's own MAC address), iptables, then use the Macvlan driver. This may be necessary to route traffic out to your/ISPs router.

https://docs.docker.com/engine/userguide/networking/get-started-macvlan

The following will create a variable length set of arguments of the type of string:

print(String arg1, String... arg2)

You can then refer to arg2 as an array of Strings. This is a new feature in Java 5.

Try this:

this.TextBox3.Text = String.Format("{0: MM.dd.yyyy}",DateTime.Now);

time = Time.now.getutc

Rationale: In my eyes a timestamp is exactly that: A point in time. This can be accurately represented with an object. If you need anything else, a scalar value, e.g. seconds since the Unix epoch, 100-ns intervals since 1601 or maybe a string for display purposes or storing the timestamp in a database, you can readily get that from the object. But that depends very much on your intended use.

Saying that »a true timestamp is the number of seconds since the Unix epoch« is a little missing the point, as that is one way of representing a point in time, but it also needs additional information to even know that you're dealing with a time and not a number. A Time object solves this problem nicely by representing a point in time and also being explicit about what it is.

Context

• Python (version 2.7.2 )

Problem

• You want to generate a urlencoded query string.
• You have a dictionary or object containing the name-value pairs.
• You want to be able to control the output ordering of the name-value pairs.

Solution

• urllib.urlencode
• urllib.quote_plus

Pitfalls

• dictionary output arbitrary ordering of name-value pairs
  • (see also: Why is python ordering my dictionary like so?)
  • (see also: Why is the order in dictionaries and sets arbitrary?)
• handling cases when you DO NOT care about the ordering of the name-value pairs
• handling cases when you DO care about the ordering of the name-value pairs
• handling cases where a single name needs to appear more than once in the set of all name-value pairs

Example

The following is a complete solution, including how to deal with some pitfalls.

### ********************
## init python (version 2.7.2 )
import urllib

### ********************
## first setup a dictionary of name-value pairs
dict_name_value_pairs = {
  "bravo"   : "True != False",
  "alpha"   : "http://www.example.com",
  "charlie" : "hello world",
  "delta"   : "1234567 !@#$%^&*",
  "echo"    : "[email protected]",
  }

### ********************
## setup an exact ordering for the name-value pairs
ary_ordered_names = []
ary_ordered_names.append('alpha')
ary_ordered_names.append('bravo')
ary_ordered_names.append('charlie')
ary_ordered_names.append('delta')
ary_ordered_names.append('echo')

### ********************
## show the output results
if('NO we DO NOT care about the ordering of name-value pairs'):
  queryString  = urllib.urlencode(dict_name_value_pairs)
  print queryString 
  """
  echo=user%40example.com&bravo=True+%21%3D+False&delta=1234567+%21%40%23%24%25%5E%26%2A&charlie=hello+world&alpha=http%3A%2F%2Fwww.example.com
  """

if('YES we DO care about the ordering of name-value pairs'):
  queryString  = "&".join( [ item+'='+urllib.quote_plus(dict_name_value_pairs[item]) for item in ary_ordered_names ] )
  print queryString
  """
  alpha=http%3A%2F%2Fwww.example.com&bravo=True+%21%3D+False&charlie=hello+world&delta=1234567+%21%40%23%24%25%5E%26%2A&echo=user%40example.com

$host is a variable of the Core module.

$host

This variable is equal to line Host in the header of request or name of the server processing the request if the Host header is not available.

This variable may have a different value from $http_host in such cases: 1) when the Host input header is absent or has an empty value, $host equals to the value of server_name directive; 2)when the value of Host contains port number, $host doesn't include that port number. $host's value is always lowercase since 0.8.17.

$http_host is also a variable of the same module but you won't find it with that name because it is defined generically as $http_HEADER (ref).

$http_HEADER

The value of the HTTP request header HEADER when converted to lowercase and with 'dashes' converted to 'underscores', e.g. $http_user_agent, $http_referer...;

Summarizing:

• $http_host equals always the HTTP_HOST request header.
• $host equals $http_host, lowercase and without the port number (if present), except when HTTP_HOST is absent or is an empty value. In that case, $host equals the value of the server_name directive of the server which processed the request.

Add relative positioning to the wrapping div tag, then absolutely position the image within it like this:

CSS:

.div-wrapper {
    position: relative;
    height: 300px;
    width: 300px;
}

.div-wrapper img {
    position: absolute;
    left: 0;
    bottom: 0;
}

HTML:

<div class="div-wrapper">
    <img src="blah.png"/>
</div>

Now the image sits at the bottom of the div.

We can use replace to change the values in 'mpg' to NA that corresponds to cyl==4.

mtcars %>%
     mutate(mpg=replace(mpg, cyl==4, NA)) %>%
     as.data.frame()

To add a bit to accepted answer ...

If you get an UnfinishedStubbingException, be sure to set the method to be stubbed after the when closure, which is different than when you write Mockito.when

Mockito.doNothing().when(mock).method()    //method is declared after 'when' closes

Mockito.when(mock.method()).thenReturn(something)   //method is declared inside 'when'

The problem with the EXIT /B solutions, when more realistically inside a batch file as just one part of it is the following. There is no subsequent processing within the said batch file after the EXIT /B. Usually there is much more to batches than just the one, limited task.

To counter that problem:

@echo off & setlocal enableextensions enabledelayedexpansion
set myfile_=C:\_D\TEST\My test file.txt
set FirstLine=
for /f "delims=" %%i in ('type "%myfile_%"') do (
  if not defined FirstLine set FirstLine=%%i)
echo FirstLine=%FirstLine%
endlocal & goto :EOF

(However, the so-called poison characters will still be a problem.)

More on the subject of getting a particular line with batch commands:

How do I get the n'th, the first and the last line of a text file?" http://www.netikka.net/tsneti/info/tscmd023.htm

[Added 28-Aug-2012] One can also have:

@echo off & setlocal enableextensions
set myfile_=C:\_D\TEST\My test file.txt
for /f "tokens=* delims=" %%a in (
  'type "%myfile_%"') do (
    set FirstLine=%%a& goto _ExitForLoop)
:_ExitForLoop
echo FirstLine=%FirstLine%
endlocal & goto :EOF

This worked for me

On the Zipped folder of the ADT you initially downloaded unzip and navigate to:

adt-bundle-windows-x86_64-20140702\eclipse\plugins

Copy all the executable jar files and paste them on the

C:\adt-bundle-windows-x86_64-20140702\adt-bundle-windows-x86_64-20140702\eclipse\plugins

directory (or wherever your adt is located).
Any executable jar files missing in the plugin folder will be added. You should be able to launch eclipse

Swift You can use following function to open Settings App with Bluetooth Page

func openSettingsApp(){
    if let settings = NSURL(string: "prefs:root=Bluetooth") {
        UIApplication.sharedApplication().openURL(settings)
    }
}

Again this would not open the App's Settings. This would open settings app with Bluetooth as this is deep linking to bluetooth.

For the correct solution after many hours:

1. Open the configuration file
2. Change the connection string with the following

<add name="umbracoDbDSN" connectionString="data source=YOUR_SERVER_NAME;database=nrc;Integrated Security=SSPI;persist security info=True;" providerName="System.Data.SqlClient" />

3. Change the YOUR_SERVER_NAME with your current server name and save
4. Open the IIS Manager
5. Find the name of the application pool that the website or web application is using
6. Right-click and choose Advanced settings
7. From Advanced settings under Process Model change the Identity to Custom account and add your Server Admin details, please see the attached images:

Hope this will help.

Also removing the submodule and then running git submodule init and git submodule update will obviously do the trick, but may not always be appropriate or possible.

You can use a function like this. Complete and modify it to your need :

/**
     * Encode URL (except :, /, ?, &, =, ... characters)
     * @param url to encode
     * @param encodingCharset url encoding charset
     * @return encoded URL
     * @throws UnsupportedEncodingException
     */
    public static String encodeUrl (String url, String encodingCharset) throws UnsupportedEncodingException{
            return new URLCodec().encode(url, encodingCharset).replace("%3A", ":").replace("%2F", "/").replace("%3F", "?").replace("%3D", "=").replace("%26", "&");
    }

Example of use :

String urlToEncode = ""http://www.growup.com/folder/intérieur-à_vendre?o=4";
Utils.encodeUrl (urlToEncode , "UTF-8")

The result is : http://www.growup.com/folder/int%C3%A9rieur-%C3%A0_vendre?o=4

Where you want to get that connection is unclear. One possibility would be to get it from the underlying Hibernate Session used by the EntityManager. With JPA 1.0, you'll have to do something like this:

Session session = (Session)em.getDelegate();
Connection conn = session.connection();

Note that the getDelegate() is not portable, the result of this method is implementation specific: the above code works in JBoss, for GlassFish you'd have to adapt it - have a look at Be careful while using EntityManager.getDelegate().

In JPA 2.0, things are a bit better and you can do the following:

Connection conn = em.unwrap(Session.class).connection();

If you are running inside a container, you could also perform a lookup on the configured DataSource.

If you forget to provide a "name" string as the second argument to the constructor, it creates an "in-memory" database which gets erased when you close the app.

No need to use any external library.

You can use this class instead :) (handles even lists , nested lists and json)

public class Utility {

    public static Map<String, Object> jsonToMap(Object json) throws JSONException {

        if(json instanceof JSONObject)
            return _jsonToMap_((JSONObject)json) ;

        else if (json instanceof String)
        {
            JSONObject jsonObject = new JSONObject((String)json) ;
            return _jsonToMap_(jsonObject) ;
        }
        return null ;
    }


   private static Map<String, Object> _jsonToMap_(JSONObject json) throws JSONException {
        Map<String, Object> retMap = new HashMap<String, Object>();

        if(json != JSONObject.NULL) {
            retMap = toMap(json);
        }
        return retMap;
    }


    private static Map<String, Object> toMap(JSONObject object) throws JSONException {
        Map<String, Object> map = new HashMap<String, Object>();

        Iterator<String> keysItr = object.keys();
        while(keysItr.hasNext()) {
            String key = keysItr.next();
            Object value = object.get(key);

            if(value instanceof JSONArray) {
                value = toList((JSONArray) value);
            }

            else if(value instanceof JSONObject) {
                value = toMap((JSONObject) value);
            }
            map.put(key, value);
        }
        return map;
    }


    public static List<Object> toList(JSONArray array) throws JSONException {
        List<Object> list = new ArrayList<Object>();
        for(int i = 0; i < array.length(); i++) {
            Object value = array.get(i);
            if(value instanceof JSONArray) {
                value = toList((JSONArray) value);
            }

            else if(value instanceof JSONObject) {
                value = toMap((JSONObject) value);
            }
            list.add(value);
        }
        return list;
    }
}

To convert your JSON string to hashmap use this :

HashMap<String, Object> hashMap = new HashMap<>(Utility.jsonToMap(

Attention: The other answers only work on SQL Servers with English configuration! Use SET DATEFIRST 7 to ensure DATEPART(DW, ...) returns 1 for Sunday and 7 for Saturday.

Here's a version that is independent of the local setting and does not require to use :

CREATE FUNCTION [dbo].[fct_IsDateWeekend] ( @date DATETIME )
RETURNS BIT
AS
BEGIN
    RETURN CASE WHEN DATEPART(DW, @date + @@DATEFIRST - 1) > 5  THEN 1 ELSE 0 END;
END;

If you don't want to use the function, simply use this in your SELECT statement:

CASE WHEN DATEPART(DW, YourDateTime + @@DATEFIRST - 1) > 5  THEN 'Weekend' ELSE 'Weekday' END

I have written myself a function that converts most of the stuff one may want to send via AJAX to GET of POST query.
Following part of the function might be of interest:

  if(data.tagName!=null&&data.tagName.toUpperCase()=="FORM") {
    //Get all the input elements in form
    var elem = data.elements;
    //Loop through the element array
    for(var i = 0; i < elem.length; i++) {
      //Ignore elements that are not supposed to be sent
      if(elem[i].disabled!=null&&elem[i].disabled!=false||elem[i].type=="button"||elem[i].name==null||(elem[i].type=="checkbox"&&elem[i].checked==false))
        continue; 
      //Add & to any subsequent entries (that means every iteration except the first one) 
      if(data_string.length>0)
        data_string+="&";
      //Get data for selectbox
      if (elem[i].tagName.toUpperCase() == "SELECT")
      {
        data_string += elem[i].name + "=" + encodeURIComponent(elem[i].options[elem[i].selectedIndex].value) ;
      }
      //Get data from checkbox
      else if(elem[i].type=="checkbox")
      {
        data_string += elem[i].name + "="+(elem[i].value==null?"on":elem[i].value);
      }
      //Get data from textfield
      else
      {
        data_string += elem[i].name + (elem[i].value!=""?"=" + encodeURIComponent(elem[i].value):"=");
      }
    }
    return data_string; 
  }

It does not need jQuery since I don't use it. But I'm sure jquery's $.post accepts string as seconf argument.

Here is the whole function, other parts are not commented though. I can't promise there are no bugs in it:

function ajax_create_request_string(data, recursion) {
  var data_string = '';
  //Zpracovani formulare
  if(data.tagName!=null&&data.tagName.toUpperCase()=="FORM") {
    //Get all the input elements in form
    var elem = data.elements;
    //Loop through the element array
    for(var i = 0; i < elem.length; i++) {
      //Ignore elements that are not supposed to be sent
      if(elem[i].disabled!=null&&elem[i].disabled!=false||elem[i].type=="button"||elem[i].name==null||(elem[i].type=="checkbox"&&elem[i].checked==false))
        continue; 
      //Add & to any subsequent entries (that means every iteration except the first one) 
      if(data_string.length>0)
        data_string+="&";
      //Get data for selectbox
      if (elem[i].tagName.toUpperCase() == "SELECT")
      {
        data_string += elem[i].name + "=" + encodeURIComponent(elem[i].options[elem[i].selectedIndex].value) ;
      }
      //Get data from checkbox
      else if(elem[i].type=="checkbox")
      {
        data_string += elem[i].name + "="+(elem[i].value==null?"on":elem[i].value);
      }
      //Get data from textfield
      else
      {
        if(elem[i].className.indexOf("autoempty")!=-1) {
          data_string += elem[i].name+"=";
        }
        else
          data_string += elem[i].name + (elem[i].value!=""?"=" + encodeURIComponent(elem[i].value):"=");
      }
    }
    return data_string; 
  }
  //Loop through array
  if(data instanceof Array) {
    for(var i=0; i<data.length; i++) {
      if(data_string!="")
        data_string+="&";
      data_string+=recursion+"["+i+"]="+data[i];
    }
    return data_string;
  }
  //Loop through object (like foreach)
  for(var i in data) {
    if(data_string!="")
      data_string+="&";
    if(typeof data[i]=="object") {
      if(recursion==null)
        data_string+= ajax_create_request_string(data[i], i);
      else
        data_string+= ajax_create_request_string(data[i], recursion+"["+i+"]");
    }
    else if(recursion==null)
      data_string+=i+"="+data[i];
    else 
      data_string+=recursion+"["+i+"]="+data[i];
  }
  return data_string;
}

If you have not tried the following command

SELECT TOP 10 * FROM big_table ORDER BY id DESC;

I see it's working when I execute the command

SELECT TOP 10 * FROM Customers ORDER BY CustomerId DESC;

in the Try it yourself command window of https://www.w3schools.com/sql/sql_func_last.asp

In powershell 2.0

split-path $pwd

You can use these steps to import the key to an existing keystore. The instructions are combined from answers in this thread and other sites. These instructions worked for me (the java keystore):

1. Run

openssl pkcs12 -export -in yourserver.crt -inkey yourkey.key -out server.p12 -name somename -certfile yourca.crt -caname root

(If required put the -chain option. Putting that failed for me). This will ask for the password - you must give the correct password else you will get an error (heading error or padding error etc).

2. It will ask you to enter a new password - you must enter a password here - enter anything but remember it. (Let us assume you enter Aragorn).
3. This will create the server.p12 file in the pkcs format.
4. Now to import it into the *.jks file run:
   keytool -importkeystore -srckeystore server.p12 -srcstoretype PKCS12 -destkeystore yourexistingjavakeystore.jks -deststoretype JKS -deststorepass existingjavastorepassword -destkeypass existingjavastorepassword
   (Very important - do not leave out the deststorepass and the destkeypass parameters.)
5. It will ask you for the src key store password. Enter Aragorn and hit enter. The certificate and key is now imported into your existing java keystore.

For Me I just wanted to see the error in my VBA application so in the function I created the below code..

This is what I did for Installing Anaconda Python 3.6 version and Tensorflow on Window 10 64bit.And It was success!

1. Download Anaconda Python 3.6 version for Window 64bit.

2. Create a conda environment named tensorflow by invoking the following command:

   C:> conda create -n tensorflow 
   

3. Activate the conda environment by issuing the following command:

   C:> activate tensorflow
   (tensorflow)C:>  # Your prompt should change 
   

4. Download “tensorflow-1.0.1-cp36-cp36m-win_amd64.whl” from here. (For my case, the file will be located in “C:\Users\Joshua\Downloads” once after downloaded).

5. Install the Tensorflow by using following command:

   (tensorflow)C:>pip install C:\Users\Joshua\Downloads\ tensorflow-1.0.1-cp36-cp36m-win_amd64.whl
   

This is what I got after the installing:

6. Validate installation by entering following command in your Python environment:

   import tensorflow as tf
   hello = tf.constant('Hello, TensorFlow!')
   sess = tf.Session()
   print(sess.run(hello))
   

If the output you got is 'Hello, TensorFlow!',that means you have successfully install your Tensorflow.

The primary purpose of the DataFrame indexing operator, [] is to select columns.

When the indexing operator is passed a string or integer, it attempts to find a column with that particular name and return it as a Series.

So, in the question above: df[2] searches for a column name matching the integer value 2. This column does not exist and a KeyError is raised.

The DataFrame indexing operator completely changes behavior to select rows when slice notation is used

Strangely, when given a slice, the DataFrame indexing operator selects rows and can do so by integer location or by index label.

df[2:3]

This will slice beginning from the row with integer location 2 up to 3, exclusive of the last element. So, just a single row. The following selects rows beginning at integer location 6 up to but not including 20 by every third row.

df[6:20:3]

You can also use slices consisting of string labels if your DataFrame index has strings in it. For more details, see this solution on .iloc vs .loc.

I almost never use this slice notation with the indexing operator as its not explicit and hardly ever used. When slicing by rows, stick with .loc/.iloc.

If you are using 19c then just follow the following steps

1. Login with sys user.
2. alter the session to the pluggable database with the following command.
3. SQL>alter session set container=orclpdb;
4. Next startup the database.
5. SQL>startup After that database will not show the above error.

Try PHP's "get_headers" function.

Something along the lines of:

<?php
    $url = 'http://www.example.com';
    print_r(get_headers($url));
    print_r(get_headers($url, 1));
?>

Here is a slightly modified version of t.dubrownik's answer. Why?

1. As a general template, you should return the return value from the original function.
2. This changes the name of the function, which could affect other decorators / code.

So use @functools.wraps():

from functools import wraps

def decorator(argument):
    def real_decorator(function):
        @wraps(function)
        def wrapper(*args, **kwargs):
            funny_stuff()
            something_with_argument(argument)
            retval = function(*args, **kwargs)
            more_funny_stuff()
            return retval
        return wrapper
    return real_decorator

    private string MonthName(int m)
    {
        string res;
        switch (m)
        {
            case 1:
                res="Ene";
                break;
            case 2:
                res = "Feb";
                break;
            case 3:
                res = "Mar";
                break;
            case 4:
                res = "Abr";
                break;
            case 5:
                res = "May";
                break;
            case 6:
                res = "Jun";
                break;
            case 7:
                res = "Jul";
                break;
            case 8:
                res = "Ago";
                break;
            case 9:
                res = "Sep";
                break;
            case 10:
                res = "Oct";
                break;
            case 11:
                res = "Nov";
                break;
            case 12:
                res = "Dic";
                break;
            default:
                res = "Nulo";
                break;
        }
        return res;
    }

Both the methods are defined in Object class. And both are in its simplest implementation. So when you need you want add some more implementation to these methods then you have override in your class.

For Ex: equals() method in object only checks its equality on the reference. So if you need compare its state as well then you can override that as it is done in String class.

What about:

PrintWriter out = response.getWriter();
out.println("THE_STRING_TO_SEND_AS_RESPONSE");
return null;

This woks for me.

From the Oracle docs:

As implied by its name, this interface models the mathematical set abstraction.

In Set Theory, "a "set" is a collection of distinct objects, considered as an object in its own right." - [Wikipedia - Set].

Mathematically, elements in sets are not individualised. Their only identity is derived from their presence in the set. Therefore, there is no point in getting the "first" element in a set, as conceptually such a task is illogical.

There may be no point to getting the "first" element from a set, but if all you need is to get one single object from a set (with no guarantees as to which object that is) you can do the following:

for(String aSiteId: siteIdSet) {
    siteId = aSiteId;
    break;
}

This is a slightly shorter way (than the method you posted) to get the "first" object of a Set, however since an Iterator is still being created (under the hood) it does not grant any performance benefit.

Try \vspace{-5mm} before the itemize.

I'd suggest getting into one of the JS libraries out there. They ensure compatibility so you can get up and running really fast. jQuery and DOJO are both really great. To do what you're trying to do in jQuery, for example, it would go something like this:

<script type="text/javascript" language="JavaScript">
$.ajax({
    url: "x.html", 
    context: document.body,
    success: function(response) {
        $("#yourDiv").html(response);
    }
});
</script>

You can use the following tag

<body oncontextmenu="return false"><!-- your page body hear--></body>

OR you can create your own menu when right click:

https://github.com/swisnl/jQuery-contextMenu

recyclerView.removeAllViewsInLayout();

The above line would help you remove all views from the layout.

For you:

@Override
protected void onRestart() {
    super.onRestart();

    recyclerView.removeAllViewsInLayout(); //removes all the views

    //then reload the data
    PostCall doPostCall = new PostCall(); //my AsyncTask... 
    doPostCall.execute();
}

I also had a similar issue. Someone might find what worked for me helpful.

Machine is running Ubuntu 16.04 and has Docker CE. After looking through the answers and links provided here, especially from the link from the Docker website given by Elliot Beach, I opened my /etc/apt/sources.list and examined it.

The file had both deb [arch=amd64] https://download.docker.com/linux/ubuntu (lsb_release -cs) stable and deb [arch=amd64] https://download.docker.com/linux/ubuntu xenial stable.

Since the second one was what was needed, I simply commented out the first, saved the document and now the issue is fixed. As a test, I went back into the same document, removed the comment sign and ran sudo apt-get update again. The issue returned when I did that.

So to recap : not only did I have my parent Ubuntu distribution name as stated on the Docker website but I also commented out the line still containing (lsb_release -cs).

In addition to @Eric Bole-Feysot answer:

Thanks to satellite assemblies, localization can be created based on .dll/.exe files. This way:

• source code (VS project) could be separated from language project,
• adding a new language does not require recompiling the project,
• translation could be made even by the end-user.

There is a little known tool called LSACreator (free for non-commercial use or buy option) which allows you to create localization based on .dll/.exe files. In fact, internally (in language project's directory) it creates/manages localized versions of resx files and compiles an assembly in similar way as @Eric Bole-Feysot described.

Other solutions are good enough to answer your query. However, if you are looking for just one command to do that for you -

Create a file name "run", in directory where your Java files are. And save this in your file -

javac "$1.java"
if [ $? -eq 0 ]; then
  echo "--------Run output-------"
  java "$1"
fi

give this file run permission by running -

chmod 777 

Now you can run any of your files by merely running -

./run <yourfilename> (don't add .java in filename)

I recommand the following article : Hit Region Detection For HTML5 Canvas And How To Listen To Click Events On Canvas Shapes which goes through various situations.

However, it does not cover the addHitRegion API, which must be the best way (using math functions and/or comparisons is quite error prone). This approach is detailed on developer.mozilla

Another version:

df[~df['EPS'].isna()]

create a textbox:

 <TextBox Name="tb">
 ..hello..
</TextBox>

focus() ---> it is used to set input focus to the textbox control

tb.focus()

The way you declare the date property as an input looks incorrect but its hard to say if it's the only problem without seeing all your code. Rather than using @Input('date') declare the date property like so: private _date: string;. Also, make sure you are instantiating the model with the new keyword. Lastly, access the property using regular dot notation.

Check your work against this example from https://www.typescriptlang.org/docs/handbook/classes.html :

let passcode = "secret passcode";

class Employee {
    private _fullName: string;

    get fullName(): string {
        return this._fullName;
    }

    set fullName(newName: string) {
        if (passcode && passcode == "secret passcode") {
            this._fullName = newName;
        }
        else {
            console.log("Error: Unauthorized update of employee!");
        }
    }
}

let employee = new Employee();
employee.fullName = "Bob Smith";
if (employee.fullName) {
    console.log(employee.fullName);
}

And here is a plunker demonstrating what it sounds like you're trying to do: https://plnkr.co/edit/OUoD5J1lfO6bIeME9N0F?p=preview

I will use collection.save(the_changed_dict) this way. I've just tested this, and it still works for me. The following is quoted directly from pymongo doc.:

save(to_save[, manipulate=True[, safe=False[, **kwargs]]])

Save a document in this collection.

If to_save already has an "_id" then an update() (upsert) operation is performed and any existing document with that "_id" is overwritten. Otherwise an insert() operation is performed. In this case if manipulate is True an "_id" will be added to to_save and this method returns the "_id" of the saved document. If manipulate is False the "_id" will be added by the server but this method will return None.

<a href="javascript:void(0)" class="aaf" id="users_id">add as a friend</a>

on jquery

$('.aaf').on("click",function(){
  var usersid =  $(this).attr("id");

})

//other method is to use the data attribute

<a href="javascript:void(0)" class="aaf" data-id="102" data-username="sample_username">add as a friend</a>

on jquery

$('.aaf').on("click",function(){
    var usersid =  $(this).data("id");
    var username = $(this).data("username");
})

What's FAT?

FAT may sound like a strange name for a file system, but it's actually an acronym for File Allocation Table. Introduced in 1981, FAT is ancient in computer terms. Because of its age, most operating systems, including Microsoft Windows NT®, Windows 98, the Macintosh OS, and some versions of UNIX, offer support for FAT.

The FAT file system limits filenames to the 8.3 naming convention, meaning that a filename can have no more than eight characters before the period and no more than three after. Filenames in a FAT file system must also begin with a letter or number, and they can't contain spaces. Filenames aren't case sensitive.

What About VFAT?

Perhaps you've also heard of a file system called VFAT. VFAT is an extension of the FAT file system and was introduced with Windows 95. VFAT maintains backward compatibility with FAT but relaxes the rules. For example, VFAT filenames can contain up to 255 characters, spaces, and multiple periods. Although VFAT preserves the case of filenames, it's not considered case sensitive.

When you create a long filename (longer than 8.3) with VFAT, the file system actually creates two different filenames. One is the actual long filename. This name is visible to Windows 95, Windows 98, and Windows NT (4.0 and later). The second filename is called an MS-DOS® alias. An MS-DOS alias is an abbreviated form of the long filename. The file system creates the MS-DOS alias by taking the first six characters of the long filename (not counting spaces), followed by the tilde [~] and a numeric trailer. For example, the filename Brien's Document.txt would have an alias of BRIEN'~1.txt.

An interesting side effect results from the way VFAT stores its long filenames. When you create a long filename with VFAT, it uses one directory entry for the MS-DOS alias and another entry for every 13 characters of the long filename. In theory, a single long filename could occupy up to 21 directory entries. The root directory has a limit of 512 files, but if you were to use the maximum length long filenames in the root directory, you could cut this limit to a mere 24 files. Therefore, you should use long filenames very sparingly in the root directory. Other directories aren't affected by this limit.

You may be wondering why we're discussing VFAT. The reason is it's becoming more common than FAT, but aside from the differences I mentioned above, VFAT has the same limitations. When you tell Windows NT to format a partition as FAT, it actually formats the partition as VFAT. The only time you'll have a true FAT partition under Windows NT 4.0 is when you use another operating system, such as MS-DOS, to format the partition.

FAT32

FAT32 is actually an extension of FAT and VFAT, first introduced with Windows 95 OEM Service Release 2 (OSR2). FAT32 greatly enhances the VFAT file system but it does have its drawbacks.

The greatest advantage to FAT32 is that it dramatically increases the amount of free hard disk space. To illustrate this point, consider that a FAT partition (also known as a FAT16 partition) allows only a certain number of clusters per partition. Therefore, as your partition size increases, the cluster size must also increase. For example, a 512-MB FAT partition has a cluster size of 8K, while a 2-GB partition has a cluster size of 32K.

This may not sound like a big deal until you consider that the FAT file system only works in single cluster increments. For example, on a 2-GB partition, a 1-byte file will occupy the entire cluster, thereby consuming 32K, or roughly 32,000 times the amount of space that the file should consume. This rule applies to every file on your hard disk, so you can see how much space can be wasted.

Converting a partition to FAT32 reduces the cluster size (and overcomes the 2-GB partition size limit). For partitions 8 GB and smaller, the cluster size is reduced to a mere 4K. As you can imagine, it's not uncommon to gain back hundreds of megabytes by converting a partition to FAT32, especially if the partition contains a lot of small files.

Note: This section of the quote/ article (1999) is out of date. Updated info quote below.

As I mentioned, FAT32 does have limitations. Unfortunately, it isn't compatible with any operating system other than Windows 98 and the OSR2 version of Windows 95. However, Windows 2000 will be able to read FAT32 partitions.

The other disadvantage is that your disk utilities and antivirus software must be FAT32-aware. Otherwise, they could interpret the new file structure as an error and try to correct it, thus destroying data in the process.

Finally, I should mention that converting to FAT32 is a one-way process. Once you've converted to FAT32, you can't convert the partition back to FAT16. Therefore, before converting to FAT32, you need to consider whether the computer will ever be used in a dual-boot environment. I should also point out that although other operating systems such as Windows NT can't directly read a FAT32 partition, they can read it across the network. Therefore, it's no problem to share information stored on a FAT32 partition with other computers on a network that run older operating systems.

Updated mentioned in comment by Doktor-J (assimilated to update out of date answer in case comment is ever lost):

I'd just like to point out that most modern operating systems (WinXP/Vista/7/8, MacOS X, most if not all Linux variants) can read FAT32, contrary to what the second-to-last paragraph suggests.

The original article was written in 1999, and being posted on a Microsoft website, probably wasn't concerned with non-Microsoft operating systems anyways.

The operating systems "excluded" by that paragraph are probably the original Windows 95, Windows NT 4.0, Windows 3.1, DOS, etc.

The chunks of SQL are blocked off with "Table structure for table my_table" and "Dumping data for table my_table."

You can use a Windows command line as follows to get the line numbers for the various sections. Adjust the searched string as needed.

find /n "for table `" sql.txt

The following will be returned:

---------- SQL.TXT

[4384]-- Table structure for table my_table

[4500]-- Dumping data for table my_table

[4514]-- Table structure for table some_other_table

... etc.

That gets you the line numbers you need... now, if I only knew how to use them... investigating.

This is one of the few cases where I find the test:

if(! argument2) {  

}

works quite nicely and carries the correct implication syntactically.

(With the simultaneous restriction that I wouldn't allow a legitimate null value for argument2 which has some other meaning; but that would be really confusing.)

EDIT:

This is a really good example of a stylistic difference between loosely-typed and strongly-typed languages; and a stylistic option that javascript affords in spades.

My personal preference (with no criticism meant for other preferences) is minimalism. The less the code has to say, as long as I'm consistent and concise, the less someone else has to comprehend to correctly infer my meaning.

One implication of that preference is that I don't want to - don't find it useful to - pile up a bunch of type-dependency tests. Instead, I try to make the code mean what it looks like it means; and test only for what I really will need to test for.

One of the aggravations I find in some other peoples' code is needing to figure out whether or not they expect, in the larger context, to actually run into the cases they are testing for. Or if they are trying to test for everything possible, on the chance that they don't anticipate the context completely enough. Which means I end up needing to track them down exhaustively in both directions before I can confidently refactor or modify anything. I figure that there's a good chance they might have put those various tests in place because they foresaw circumstances where they would be needed (and which usually aren't apparent to me).

(I consider that a serious downside in the way these folks use dynamic languages. Too often people don't want to give up all the static tests, and end up faking it.)

I've seen this most glaringly in comparing comprehensive ActionScript 3 code with elegant javascript code. The AS3 can be 3 or 4 times the bulk of the js, and the reliability I suspect is at least no better, just because of the number (3-4X) of coding decisions that were made.

As you say, Shog9, YMMV. :D

Two options

for(int i = 0, n = s.length() ; i < n ; i++) { 
    char c = s.charAt(i); 
}

or

for(char c : s.toCharArray()) {
    // process c
}

The first is probably faster, then 2nd is probably more readable.

Do

npm install

to install Grunt locally in ./node_modules (and everything else specified in the package.json file)

I've faced same problem with my registry then i tried the solution listed below from a blog page. It works.

Step 1: Listing catalogs

You can list your catalogs by calling this url:

http://YourPrivateRegistyIP:5000/v2/_catalog

Response will be in the following format:

{
  "repositories": [
    <name>,
    ...
  ]
}

Step 2: Listing tags for related catalog

You can list tags of your catalog by calling this url:

http://YourPrivateRegistyIP:5000/v2/<name>/tags/list

Response will be in the following format:

{
"name": <name>,
"tags": [
    <tag>,
    ...
]

}

Step 3: List manifest value for related tag

You can run this command in docker registry container:

curl -v --silent -H "Accept: application/vnd.docker.distribution.manifest.v2+json" -X GET http://localhost:5000/v2/<name>/manifests/<tag> 2>&1 | grep Docker-Content-Digest | awk '{print ($3)}'

Response will be in the following format:

sha256:6de813fb93debd551ea6781e90b02f1f93efab9d882a6cd06bbd96a07188b073

Run the command given below with manifest value:

curl -v --silent -H "Accept: application/vnd.docker.distribution.manifest.v2+json" -X DELETE http://127.0.0.1:5000/v2/<name>/manifests/sha256:6de813fb93debd551ea6781e90b02f1f93efab9d882a6cd06bbd96a07188b073

Step 4: Delete marked manifests

Run this command in your docker registy container:

bin/registry garbage-collect  /etc/docker/registry/config.yml  

Here is my config.yml

root@c695814325f4:/etc# cat /etc/docker/registry/config.yml
version: 0.1
log:
  fields:
  service: registry
storage:
    cache:

    delete:
        enabled: true

Android SDK Build Tools are exactly what the name says they are; tools for building Android Applications.It is very important to use the latest build tools version (selected automatically by your IDE via the Android SDK) but the reason the old versions are left there is to support backward compatibility, that is If your projects depend on older versions of the Build Tools.

Below solution is a clean work around.It does not compromises security because we are using same strict firewall.

The Steps for fixing is as below:

STEP 1 : Create a Class overriding StrictHttpFirewall as below.

package com.biz.brains.project.security.firewall;

            }

            j = i;
        }

        return true;
    }

}

STEP 2 : Create a FirewalledResponse class

package com.biz.brains.project.security.firewall;

import java.io.IOException;
import java.util.regex.Pattern;

import javax.servlet.http.Cookie;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpServletResponseWrapper;

class FirewalledResponse extends HttpServletResponseWrapper {
    private static final Pattern CR_OR_LF = Pattern.compile("\\r|\\n");
    private static final String LOCATION_HEADER = "Location";
    private static final String SET_COOKIE_HEADER = "Set-Cookie";

    public FirewalledResponse(HttpServletResponse response) {
        super(response);
    }

    @Override
    public void sendRedirect(String location) throws IOException {
        // TODO: implement pluggable validation, instead of simple blacklisting.
        // SEC-1790. Prevent redirects containing CRLF
        validateCrlf(LOCATION_HEADER, location);
        super.sendRedirect(location);
    }

    @Override
    public void setHeader(String name, String value) {
        validateCrlf(name, value);
        super.setHeader(name, value);
    }

    @Override
    public void addHeader(String name, String value) {
        validateCrlf(name, value);
        super.addHeader(name, value);
    }

    @Override
    public void addCookie(Cookie cookie) {
        if (cookie != null) {
            validateCrlf(SET_COOKIE_HEADER, cookie.getName());
            validateCrlf(SET_COOKIE_HEADER, cookie.getValue());
            validateCrlf(SET_COOKIE_HEADER, cookie.getPath());
            validateCrlf(SET_COOKIE_HEADER, cookie.getDomain());
            validateCrlf(SET_COOKIE_HEADER, cookie.getComment());
        }
        super.addCookie(cookie);
    }

    void validateCrlf(String name, String value) {
        if (hasCrlf(name) || hasCrlf(value)) {
            throw new IllegalArgumentException(
                    "Invalid characters (CR/LF) in header " + name);
        }
    }

    private boolean hasCrlf(String value) {
        return value != null && CR_OR_LF.matcher(value).find();
    }
}

STEP 3: Create a custom Filter to suppress the RejectedException

package com.biz.brains.project.security.filter;

import java.io.IOException;
import java.util.Objects;

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

import org.springframework.core.Ordered;
import org.springframework.core.annotation.Order;
import org.springframework.http.HttpHeaders;
import org.springframework.security.web.firewall.RequestRejectedException;
import org.springframework.stereotype.Component;
import org.springframework.web.filter.GenericFilterBean;

import lombok.extern.slf4j.Slf4j;

@Component
@Slf4j
@Order(Ordered.HIGHEST_PRECEDENCE)
public class RequestRejectedExceptionFilter extends GenericFilterBean {

        @Override
        public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain) throws IOException, ServletException {
            try {
                RequestRejectedException requestRejectedException=(RequestRejectedException) servletRequest.getAttribute("isNormalized");
                if(Objects.nonNull(requestRejectedException)) {
                    throw requestRejectedException;
                }else {
                    filterChain.doFilter(servletRequest, servletResponse);
                }
            } catch (RequestRejectedException requestRejectedException) {
                HttpServletRequest httpServletRequest = (HttpServletRequest) servletRequest;
                HttpServletResponse httpServletResponse = (HttpServletResponse) servletResponse;
                log
                    .error(
                            "request_rejected: remote={}, user_agent={}, request_url={}",
                            httpServletRequest.getRemoteHost(),  
                            httpServletRequest.getHeader(HttpHeaders.USER_AGENT),
                            httpServletRequest.getRequestURL(), 
                            requestRejectedException
                    );

                httpServletResponse.sendError(HttpServletResponse.SC_NOT_FOUND);
            }
        }
}

STEP 4: Add the custom filter to spring filter chain in security configuration

@Override
protected void configure(HttpSecurity http) throws Exception {
     http.addFilterBefore(new RequestRejectedExceptionFilter(),
             ChannelProcessingFilter.class);
}

Now using above fix, we can handle RequestRejectedException with Error 404 page.

Developers using a mybatis-like framework will prefer != over <>. Reason being the <> will need to be wrapped in CDATA as it could be interpreted as xml syntax. Easier on the eyes too.

According to the spec RFC 2045 #Syntax of the Content-Type Header Field application/myappname is not allowed, but application/x-myappname is allowed and sounds most appropriate for you're application to me.

This is a shortcut for $(document).ready(), which is executed when the browser has finished loading the page (meaning here, "when the DOM is available"). See http://www.learningjquery.com/2006/09/introducing-document-ready. If you are trying to call example() before the browser has finished loading the page, it may not work.

Don't forget to seed the RNG with srand() first.

You'll have to use an HttpServletRequestWrapper:

public void doFilter(final ServletRequest request, final ServletResponse response, final FilterChain chain) throws IOException, ServletException {
    final HttpServletRequest httpRequest = (HttpServletRequest) request;
    HttpServletRequestWrapper wrapper = new HttpServletRequestWrapper(httpRequest) {
        @Override
        public String getHeader(String name) {
            final String value = request.getParameter(name);
            if (value != null) {
                return value;
            }
            return super.getHeader(name);
        }
    };
    chain.doFilter(wrapper, response);
}

Depending on what you want to do you may need to implement other methods of the wrapper like getHeaderNames for instance. Just be aware that this is trusting the client and allowing them to manipulate any HTTP header. You may want to sandbox it and only allow certain header values to be modified this way.

With JPA 2.1 you should be able to do it.

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.Index;
import javax.persistence.Table;

@Entity
@Table(name = "region",
       indexes = {@Index(name = "my_index_name",  columnList="iso_code", unique = true),
                  @Index(name = "my_index_name2", columnList="name",     unique = false)})
public class Region{

    @Column(name = "iso_code", nullable = false)
    private String isoCode;

    @Column(name = "name", nullable = false)
    private String name;

} 

Update: If you ever need to create and index with two or more columns you may use commas. For example:

@Entity
@Table(name    = "company__activity", 
       indexes = {@Index(name = "i_company_activity", columnList = "activity_id,company_id")})
public class CompanyActivity{

i think it will depend on many things - run EXPLAIN PLAN on each one to see what your optimizer selects. Otherwise - as @rayman suggests - run them both and time them.

How host name verification should be done is defined in RFC 6125, which is quite recent and generalises the practice to all protocols, and replaces RFC 2818, which was specific to HTTPS. (I'm not even sure Java 7 uses RFC 6125, which might be too recent for this.)

From RFC 2818 (Section 3.1):

If a subjectAltName extension of type dNSName is present, that MUST be used as the identity. Otherwise, the (most specific) Common Name field in the Subject field of the certificate MUST be used. Although the use of the Common Name is existing practice, it is deprecated and Certification Authorities are encouraged to use the dNSName instead.

[...]

In some cases, the URI is specified as an IP address rather than a hostname. In this case, the iPAddress subjectAltName must be present in the certificate and must exactly match the IP in the URI.

Essentially, the specific problem you have comes from the fact that you're using IP addresses in your CN and not a host name. Some browsers might work because not all tools follow this specification strictly, in particular because "most specific" in RFC 2818 isn't clearly defined (see discussions in RFC 6215).

If you're using keytool, as of Java 7, keytool has an option to include a Subject Alternative Name (see the table in the documentation for -ext): you could use -ext san=dns:www.example.com or -ext san=ip:10.0.0.1.

EDIT:

You can request a SAN in OpenSSL by changing openssl.cnf (it will pick the copy in the current directory if you don't want to edit the global configuration, as far as I remember, or you can choose an explicit location using the OPENSSL_CONF environment variable).

Set the following options (find the appropriate sections within brackets first):

[req]
req_extensions = v3_req

[ v3_req ]
subjectAltName=IP:10.0.0.1
# or subjectAltName=DNS:www.example.com

There's also a nice trick to use an environment variable for this (rather in than fixing it in a configuration file) here: http://www.crsr.net/Notes/SSL.html

This is works for me. tyr this

exec(“php asyn.php”.” > /dev/null 2>/dev/null &“);

Martijn's method as a prototype function:

String.prototype.escape = function() {
    var tagsToReplace = {
        '&': '&',
        '<': '&lt;',
        '>': '&gt;'
    };
    return this.replace(/[&<>]/g, function(tag) {
        return tagsToReplace[tag] || tag;
    });
};

var a = "<abc>";
var b = a.escape(); // "&lt;abc&gt;"

that depends on what you want to markup.

• if you want a link inside a span, put <a> inside <span>.
• if you want to markup something in a link, put <span> into <a>

In my case, even though Target Framework of Project was 4.7.1, I was still getting same Error, Solution was to change httpRuntime in web.config under system.web to 4.7.1!

Remember that HTML and XML are two distinct concepts in the tree of markup languages. You can't exactly replace HTML with XML . XML can be viewed as a generalized form of HTML, but even that is imprecise. You mainly use HTML to display data, and XML to carry(or store) the data.

This link is helpful: How to read HTML as XML?

More here - difference between HTML and XML

Do Like this

1st put all your HTML content to array, then do json_encode

$html_content="<p>hello this is sample text";
$json_array=array(

'content'=>50,
'html_content'=>$html_content
);
echo json_encode($json_array);

I have wondered the same thing. Basically it appears that the html spec has different content types for html and form data. Json only has a single content type.

According to the spec, a POST of json data should have the content-type:
application/json

Relevant portion of the HTML spec

6.7 Content types (MIME types)
...
Examples of content types include "text/html", "image/png", "image/gif", "video/mpeg", "text/css", and "audio/basic".

17.13.4 Form content types
...
application/x-www-form-urlencoded
This is the default content type. Forms submitted with this content type must be encoded as follows

Relevant portion of the JSON spec

1. IANA Considerations
   The MIME media type for JSON text is application/json.

I just used the event input and it worked fine as follows:

in .html file :

<input type="text" class="form-control" (input)="onSearchChange($event.target.value)">

in .ts file :

onSearchChange(searchValue: string): void {  
  console.log(searchValue);
}

The error shows that com.bd.service.ArticleService is not a registered bean. Add the packages in which you have beans that will be autowired in your application context:

<context:component-scan base-package="com.bd.service"/>
<context:component-scan base-package="com.bd.controleur"/>

Alternatively, if you want to include all subpackages in com.bd:

<context:component-scan base-package="com.bd">
     <context:include-filter type="aspectj" expression="com.bd.*" />
</context:component-scan>

As a side note, if you're using Spring 3.1 or later, you can take advantage of the @ComponentScan annotation, so that you don't have to use any xml configuration regarding component-scan. Use it in conjunction with @Configuration.

@Controller
@RequestMapping("/Article/GererArticle")
@Configuration
@ComponentScan("com.bd.service") // No need to include component-scan in xml
public class ArticleControleur {

    @Autowired
    ArticleService articleService;
    ...
}

You might find this Spring in depth section on Autowiring useful.

Try this, it will give you particular column's value

onSelectRow: function(id) {
    var rowData = jQuery(this).getRowData(id); 
    var temp= rowData['name'];//replace name with you column
    alert(temp);
}

If you want to use an OR operator on one column's value, you can pass an array to .where and ActiveRecord will use IN(value,other_value):

Model.where(:column => ["value", "other_value"]

outputs:

SELECT `table_name`.* FROM `table_name` WHERE `table_name`.`column` IN ('value', 'other_value')

This should achieve the equivalent of an OR on a single column

CheckBoxFor takes a bool, you're passing a List<CheckBoxes> to it. You'd need to do:

@for (int i = 0; i < Model.EmploymentType.Count; i++)
{
    @Html.CheckBoxFor(m => m.EmploymentType[i].Checked, new { id = "employmentType_" + i })
    @Html.HiddenFor(m => m.EmploymentType[i].Text)
    @Html.DisplayFor(m => m.EmploymentType[i].Text)
}

Notice I've added a HiddenFor for the Text property too, otherwise you'd lose that when you posted the form, so you wouldn't know which items you'd checked.

Edit, as shown in your comments, your EmploymentType list is null when the view is served. You'll need to populate that too, by doing this in your action method:

public ActionResult YourActionMethod()
{
    CareerForm model = new CareerForm();

    model.EmploymentType = new List<CheckBox>
    {
        new CheckBox { Text = "Fulltime" },
        new CheckBox { Text = "Partly" },
        new CheckBox { Text = "Contract" }
    };

    return View(model);
}

Should be probably changed to

firstName = firstName.trim().replaceAll("\\.", "");

The find command will take long time, the fastest way to search for file is using locate command, which looks for file names (and path) in a indexed database (updated by command updatedb).

The result will appear immediately with a simple command:

locate {file-name-or-path}

If the command is not found, you need to install mlocate package and run updatedb command first to prepare the search database for the first time.

More detail here: https://medium.com/@thucnc/the-fastest-way-to-find-files-by-filename-mlocate-locate-commands-55bf40b297ab

The id that got generated for your drop down control in the html will be dynamic one. So use the complete id $('ct100_<Your control id>').val(). It will work.

The best way is to check the contects of the text box whenever it loses focus.

You can check whether the contents are a "number" using a regular expression.

Or you can use the Validation plugin, which basically does this automatically.

function Hello()
{
    alert("caller is " + Hello.caller);
}

Note that this feature is non-standard, from Function.caller:

Non-standard
This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.

The following is the old answer from 2008, which is no longer supported in modern Javascript:

function Hello()
{
    alert("caller is " + arguments.callee.caller.toString());
}

Or if you want to have your own implementation, I wrote this quick function as an example:

/**
 * hex2int
 * take a hex string and convert it to a 32bit number (max 8 hex digits)
 */
uint32_t hex2int(char *hex) {
    uint32_t val = 0;
    while (*hex) {
        // get current character then increment
        uint8_t byte = *hex++; 
        // transform hex character to the 4bit equivalent number, using the ascii table indexes
        if (byte >= '0' && byte <= '9') byte = byte - '0';
        else if (byte >= 'a' && byte <='f') byte = byte - 'a' + 10;
        else if (byte >= 'A' && byte <='F') byte = byte - 'A' + 10;    
        // shift 4 to make space for new digit, and add the 4 bits of the new digit 
        val = (val << 4) | (byte & 0xF);
    }
    return val;
}

The data structure of shape (n,) is called a rank 1 array. It doesn't behave consistently as a row vector or a column vector which makes some of its operations and effects non intuitive. If you take the transpose of this (n,) data structure, it'll look exactly same and the dot product will give you a number and not a matrix. The vectors of shape (n,1) or (1,n) row or column vectors are much more intuitive and consistent.

Similar to this answer, here is an example with fs2 (version 1.0.4):

import cats.effect._

import fs2._
import fs2.io

import java.nio.file._

import scala.concurrent.ExecutionContext
import scala.language.higherKinds
import cats.syntax.functor._

object ScalaApp extends IOApp {

  def write[T[_]](p: Path, s: String)
                 (implicit F: ConcurrentEffect[T], cs: ContextShift[T]): T[Unit] = {
    Stream(s)
      .covary[T]
      .through(text.utf8Encode)
      .through(
        io.file.writeAll(
          p,
          scala.concurrent.ExecutionContext.global,
          Seq(StandardOpenOption.CREATE)
        )
      )
      .compile
      .drain
  }


  def run(args: List[String]): IO[ExitCode] = {

    implicit val executionContext: ExecutionContext =
      scala.concurrent.ExecutionContext.Implicits.global

    implicit val contextShift: ContextShift[IO] =
      IO.contextShift(executionContext)

    val outputFile: Path = Paths.get("output.txt")

    write[IO](outputFile, "Hello world\n").as(ExitCode.Success)

  }
}

A pretty nice way to do this is to use SimpleDateFormat I'll show you how:

SimpleDateFormat sdf = new SimpleDateFormat("d MMMM YYYY");
Date d = new Date();
sdf.format(d);

I see that you have the date in a variable:

sdf.format(variable_name);

Cheers.

I ended up overriding the OnPaint and OnBackgroundPaint events and manually drawing the button exactly like I need it. It worked pretty well.

Since there were no exact answers to my question, I made some investigation why my code doesn't work when there are other solutions that works, and decided to post what I found to complete the subject.
As it turns out:

"ssh uses direct TTY access to make sure that the password is indeed issued by an interactive keyboard user." sshpass manpage

which answers the question, why the pipes don't work in this case. The obvious solution was to create conditions so that ssh "thought" that it is run in the regular terminal and since it may be accomplished by simple posix functions, it is beyond what simple bash offers.

The warning from your compiler is telling you that your format specifier doesn't match the data type you're passing to it.

Try using %lx or %llx. For more portability, include inttypes.h and use the PRIx64 macro.

For example: printf("val = 0x%" PRIx64 "\n", val); (note that it's string concatenation)

This seems to be the best solution I’ve found to this problem, as long as your browser supports the ::before pseudo element: CSS-Tricks: Centering in the Unknown.

It doesn’t require any extra markup and seems to work extremely well. I couldn’t use the display: table method because table elements don’t obey the max-height property.

Have to make sure you are not getting an IEnumerable<int> as a return

XAMPP comes preloaded with the FileZilla FTP server. Here is how to setup the service, and create an account.

1. Enable the FileZilla FTP Service through the XAMPP Control Panel to make it startup automatically (check the checkbox next to filezilla to install the service). Then manually start the service.

2. Create an ftp account through the FileZilla Server Interface (its the essentially the filezilla control panel). There is a link to it Start Menu in XAMPP folder. Then go to Users->Add User->Stuff->Done.

3. Try connecting to the server (localhost, port 21).

A possible solution would be to check your proxy settings; under Windows 7 you can find those settings in the other.xml file present under the path C:\Users\YourUsername\\.AndroidStudio\config\options.

Note that if you turn both options "USE_HTTP_PROXY" and "USE_PROXY_PAC" to true the error keep coming but a pop-up should come out noticing the problem of a double configuration and prompting a resolution with a input window for those settings.

UPDATE - Possible solution

I've just managed to complete the wizard at home, maybe the proxy is not the real problem (as the last comment of @meanderingmoose pointed out). It seems there is a problem with the default installer of Android Studio 1.0.0, the one that contain both the IDE and di SDK Tools: the default installation path for the android sdk tools ends with myInstallPath../sdk/android-sdk but the first run setting for the Android Studio points at ..myInstallPath../sdk. So here is what i did.

• Cut & Paste the content of the android-sdk folder outside the folder, so the files are under ..myInstallPath../sdk/
• Use SDK Manager from the new location to update everything (Use this instead of the automatic wizard, you can select which package you want or need and you get also the speed and estimate time for the download)
• Run Android Studio (it should load and check that the SDK is up to date and start the creation of an AVD, after that the IDE will load completely)

UPDATE - Workaround for the "download interrupted: read timed out" problem

The firewall and the proxy prevented my SDK Manager to download some updates, so i've recovered the .xml url for these updates, searched for the .zip files i needed and directly downloaded them with the help of a download manager, then i've manually installed them in their relative folder under the sdk folder ..a bit tricky but worked for me. For example in the Addon_xml_file i've searched for the m2repository, found the entry and downloaded the archive with the link m2repository_r14_zip_file. You always find the files you need in the same base as the .xml file (take a look at the url i've posted for the example).

It is not necessary to use withRouter. This works for me:

In your parent page,

<BrowserRouter>
   <Switch>
        <Route path="/routeA" render={(props)=> (
          <ComponentA {...props} propDummy={50} />
        )} />

        <Route path="/routeB" render={(props)=> (
          <ComponentB {...props} propWhatever={100} />
          )} /> 
      </Switch>
</BrowserRouter>

Then in ComponentA or ComponentB you can access

this.props.history

object, including the this.props.history.push method.

This error is a result of the protection level of ClassB's constructor, not ClassB itself. Since the name of the constructor is the same as the name of the class^* , the error may be interpreted incorrectly. Since you did not specify the protection level of your constructor, it is assumed to be internal by default. Declaring the constructor public will fix this problem:

public ClassB() { } 

^* One could also say that constructors have no name, only a type; this does not change the essence of the problem.

Since you use url-loader:

The url-loader works like the file-loader, but can return a DataURL if the file is smaller than a byte limit.

So another solution to this problem would be making the limit higher enough that the font files are included as DataURL, for example to 100000 which are more or less 100Kb:

{
  module: {
    loaders: [
      // ...
      {
        test: /\.scss$/,
        loaders: ['style', 'css?sourceMap', 'autoprefixer', 'sass?sourceMap'],
      },
      {
        test: /images\/.*\.(png|jpg|svg|gif)$/,
        loader: 'url-loader?limit=10000&name="[name]-[hash].[ext]"',
      },
      {
        test: /\.woff(\?v=\d+\.\d+\.\d+)?$/,
        use: 'url-loader?limit=100000&mimetype=application/font-woff',
      },
      {
        test: /\.woff2(\?v=\d+\.\d+\.\d+)?$/,
        use: 'url-loader?limit=100000&mimetype=application/font-woff',
      },
      {
        test: /\.ttf(\?v=\d+\.\d+\.\d+)?$/,
        use: 'url-loader?limit=100000&mimetype=application/octet-stream',
      },
      {
        test: /\.eot(\?v=\d+\.\d+\.\d+)?$/,
        use: 'file-loader',
      },
      {
        test: /\.svg(\?v=\d+\.\d+\.\d+)?$/,
        use: 'url-loader?limit=100000&mimetype=image/svg+xml',
      },
    ],
  },
}

Allways taking into account on what the limit number represents:

Byte limit to inline files as Data URL

This way you don't need to specify the whole URL of the assets. Which can be difficult when you want Webpack to not only respond from localhost.

Just one last consideration, this configuration is NOT RECOMMENDED for production. This is just for development easiness.

Best way to copy all files from one folder to another using PHP

<?php
$src = "/home/www/example.com/source/folders/123456";  // source folder or file
$dest = "/home/www/example.com/test/123456";   // destination folder or file        

shell_exec("cp -r $src $dest");

echo "<H2>Copy files completed!</H2>"; //output when done
?>

Another version...

Use strtol, wrapping it inside a simple function to hide its complexity :

inline bool isInteger(const std::string & s)
{
   if(s.empty() || ((!isdigit(s[0])) && (s[0] != '-') && (s[0] != '+'))) return false;

   char * p;
   strtol(s.c_str(), &p, 10);

   return (*p == 0);
}

Why strtol ?

As far as I love C++, sometimes the C API is the best answer as far as I am concerned:

• using exceptions is overkill for a test that is authorized to fail
• the temporary stream object creation by the lexical cast is overkill and over-inefficient when the C standard library has a little known dedicated function that does the job.

How does it work ?

strtol seems quite raw at first glance, so an explanation will make the code simpler to read :

strtol will parse the string, stopping at the first character that cannot be considered part of an integer. If you provide p (as I did above), it sets p right at this first non-integer character.

My reasoning is that if p is not set to the end of the string (the 0 character), then there is a non-integer character in the string s, meaning s is not a correct integer.

The first tests are there to eliminate corner cases (leading spaces, empty string, etc.).

This function should be, of course, customized to your needs (are leading spaces an error? etc.).

Sources :

See the description of strtol at: http://en.cppreference.com/w/cpp/string/byte/strtol.

See, too, the description of strtol's sister functions (strtod, strtoul, etc.).

That's exactly what cursor: pointer; is supposed to do.

If you want the cursor to remain normal, you should be using cursor: default

'.'.join() or ".".join().. So any string instance has the method join()

I had the same issue. I solved it by using the following steps(Editor: IntelliJ):

1. View -> Tool Windows -> Maven Project. Opens your projects in a sub-window.
2. Click on the arrow next to your project.
3. Click on the lifecycle.
4. Click on clean.

<div class="container">_x000D_
    <div class="row">_x000D_
        <div class="col d-flex justify-content-center">_x000D_
             CenterContent_x000D_
        </div>_x000D_
    </div>_x000D_
</div>

Enable 'flex' for the column as we want & use justify-content-center

Yes, it can. However, there can only be one public class per .java file, as public classes must have the same name as the source file.

I posted my answer even though another answer has already been accepted; the accepted answer relies on a deprecated function; additionally, this deprecated function is based on Singular Value Decomposition (SVD), which (although perfectly valid) is the much more memory- and processor-intensive of the two general techniques for calculating PCA. This is particularly relevant here because of the size of the data array in the OP. Using covariance-based PCA, the array used in the computation flow is just 144 x 144, rather than 26424 x 144 (the dimensions of the original data array).

Here's a simple working implementation of PCA using the linalg module from SciPy. Because this implementation first calculates the covariance matrix, and then performs all subsequent calculations on this array, it uses far less memory than SVD-based PCA.

(the linalg module in NumPy can also be used with no change in the code below aside from the import statement, which would be from numpy import linalg as LA.)

The two key steps in this PCA implementation are:

• calculating the covariance matrix; and

• taking the eivenvectors & eigenvalues of this cov matrix

In the function below, the parameter dims_rescaled_data refers to the desired number of dimensions in the rescaled data matrix; this parameter has a default value of just two dimensions, but the code below isn't limited to two but it could be any value less than the column number of the original data array.

def PCA(data, dims_rescaled_data=2):
    """
    returns: data transformed in 2 dims/columns + regenerated original data
    pass in: data as 2D NumPy array
    """
    import numpy as NP
    from scipy import linalg as LA
    m, n = data.shape
    # mean center the data
    data -= data.mean(axis=0)
    # calculate the covariance matrix
    R = NP.cov(data, rowvar=False)
    # calculate eigenvectors & eigenvalues of the covariance matrix
    # use 'eigh' rather than 'eig' since R is symmetric, 
    # the performance gain is substantial
    evals, evecs = LA.eigh(R)
    # sort eigenvalue in decreasing order
    idx = NP.argsort(evals)[::-1]
    evecs = evecs[:,idx]
    # sort eigenvectors according to same index
    evals = evals[idx]
    # select the first n eigenvectors (n is desired dimension
    # of rescaled data array, or dims_rescaled_data)
    evecs = evecs[:, :dims_rescaled_data]
    # carry out the transformation on the data using eigenvectors
    # and return the re-scaled data, eigenvalues, and eigenvectors
    return NP.dot(evecs.T, data.T).T, evals, evecs

def test_PCA(data, dims_rescaled_data=2):
    '''
    test by attempting to recover original data array from
    the eigenvectors of its covariance matrix & comparing that
    'recovered' array with the original data
    '''
    _ , _ , eigenvectors = PCA(data, dim_rescaled_data=2)
    data_recovered = NP.dot(eigenvectors, m).T
    data_recovered += data_recovered.mean(axis=0)
    assert NP.allclose(data, data_recovered)


def plot_pca(data):
    from matplotlib import pyplot as MPL
    clr1 =  '#2026B2'
    fig = MPL.figure()
    ax1 = fig.add_subplot(111)
    data_resc, data_orig = PCA(data)
    ax1.plot(data_resc[:, 0], data_resc[:, 1], '.', mfc=clr1, mec=clr1)
    MPL.show()

>>> # iris, probably the most widely used reference data set in ML
>>> df = "~/iris.csv"
>>> data = NP.loadtxt(df, delimiter=',')
>>> # remove class labels
>>> data = data[:,:-1]
>>> plot_pca(data)

The plot below is a visual representation of this PCA function on the iris data. As you can see, a 2D transformation cleanly separates class I from class II and class III (but not class II from class III, which in fact requires another dimension).

If you are after the side effects that happen within the loop, I'd personally go for the range() approach.

If you care about the result of whatever functions you call within the loop, I'd go for a list comprehension or map approach. Something like this:

def f(n):
    return n * n

results = [f(i) for i in range(50)]
# or using map:
results = map(f, range(50))

To my knowledge, no.

Circumstantial indications from $LC_CTYPE, locale and such might seem alluring, but these are completely separated from the encoding the terminal application (actually an emulator) happens to be using when displaying characters on the screen.

They only way to detect encoding for sure is to output something only present in the encoding, e.g. ä, take a screenshot, analyze that image and check if the output character is correct.

So no, it's not possible, sadly.

ALTER TABLE table_name CONVERT to CHARACTER SET utf8;

*IMPORTANT: Back-up first, execute after

I resolved it like this:

<% @user.errors.each do |attr, msg| %>
  <li>
    <%= @user.errors.full_messages_for(attr).first if @user.errors[attr].first == msg %>
  </li>
<% end %>

This way you are using the locales for the error messages.

While the question has been answered, I'd like to add some useful tips when using matplotlib.pyplot.savefig. The file format can be specified by the extension:

from matplotlib import pyplot as plt

plt.savefig('foo.png')
plt.savefig('foo.pdf')

Will give a rasterized or vectorized output respectively, both which could be useful. In addition, you'll find that pylab leaves a generous, often undesirable, whitespace around the image. You can remove the whitespace using:

plt.savefig('foo.png', bbox_inches='tight')

Here is a work around for IE 10 and 11 users that seemed pretty straight forward.

var elem = document.getElementById('elem');

['first','second','third'].forEach(item => elem.classList.add(item));

<div id="elem">Hello World!</div>

Or

var elem = document.getElementById('elem'),
    classes = ['first','second','third'];

classes.forEach(function(item) {
    return elem.classList.add(item);
});

<div id="elem">Hello World!</div>

Scott Gu's quoted blog post explains it nicely.

For me, the answer to the question is in the following statement in that post:

Note how the static method above has a "this" keyword before the first parameter argument of type string. This tells the compiler that this particular Extension Method should be added to objects of type "string". Within the IsValidEmailAddress() method implementation I can then access all of the public properties/methods/events of the actual string instance that the method is being called on, and return true/false depending on whether it is a valid email or not.

          <table id="myData">

          </table>

           <script type="text/javascript">
              $('#search').click(function() {
                    alert("submit handler has fired");
                    $.ajax({
                        type: 'POST',
                        url: 'cityResults.htm',
                        data: $('#cityDetails').serialize(),

                        success: function(data){ 
                            $.each(data, function( index, value ) {
                               var row = $("<tr><td>" + value.city + "</td><td>" + value.cStatus + "</td></tr>");
                               $("#myData").append(row);
                            });
                        },
                        error: function(jqXHR, textStatus, errorThrown){
                            alert('error: ' + textStatus + ': ' + errorThrown);
                        }
                    });
                    return false;//suppress natural form submission
                }); 

   </script>

loop through the data and append it to a table like the code above.

If you don't care about the order of the array, then you may want to get the difference between arr1 and arr2 by id using differenceBy() and then simply use concat() to append all the updated objects.

var result = _(arr1).differenceBy(arr2, 'id').concat(arr2).value();

var arr1 = [{_x000D_
  id: '124',_x000D_
  name: 'qqq'_x000D_
}, {_x000D_
  id: '589',_x000D_
  name: 'www'_x000D_
}, {_x000D_
  id: '45',_x000D_
  name: 'eee'_x000D_
}, {_x000D_
  id: '567',_x000D_
  name: 'rrr'_x000D_
}]_x000D_
_x000D_
var arr2 = [{_x000D_
  id: '124',_x000D_
  name: 'ttt'_x000D_
}, {_x000D_
  id: '45',_x000D_
  name: 'yyy'_x000D_
}];_x000D_
_x000D_
var result = _(arr1).differenceBy(arr2, 'id').concat(arr2).value();_x000D_
_x000D_
console.log(result);

<script src="https://cdnjs.cloudflare.com/ajax/libs/lodash.js/4.13.1/lodash.js"></script>

Just some other formatting options:

printf("name: %s\targs: %s\tvalue %d\tarraysize %d\n", 
        a,        b,        c,        d);

printf("name: %s\targs: %s\tvalue %d\tarraysize %d\n", 
              a,        b,        c,            d);

printf("name: %s\t"      "args: %s\t"      "value %d\t"      "arraysize %d\n", 
        very_long_name_a, very_long_name_b, very_long_name_c, very_long_name_d);

You can add variations on the theme. The idea is that the printf() conversion speficiers and the respective variables are all lined up "nicely" (for some values of "nicely").

You need to ensure that the contents of your file_paths.xml file contains this string => "/Android/data/com.example.marek.myapplication/files/Pictures/"

From the error message, that is path where your pictures are stored. See sample of expected

files_path.xml below:

<external-path name="qit_images" path="Android/data/com.example.marek.myapplication/files/Pictures/" />

You can also try this to determine the current global sql_mode value:

SELECT @@GLOBAL.sql_mode;

or session sql_mode value:

SELECT @@SESSION.sql_mode;

I also had the feeling that the SQL mode was indeed empty.

The below code work fine with me of sure thanks for the above comments. You can add report viewer and change the visible=false and use the below code on submit button:

protected void Button1_Click(object sender, EventArgs e)
{
    Warning[] warnings;
    string[] streamIds;
    string mimeType = string.Empty;
    string encoding = string.Empty;
    string extension = string.Empty;
    string HIJRA_TODAY = "01/10/1435";
    ReportParameter[] param = new ReportParameter[3];
    param[0] = new ReportParameter("CUSTOMER_NUM", CUSTOMER_NUMTBX.Text);
    param[1] = new ReportParameter("REF_CD", REF_CDTB.Text);
    param[2] = new ReportParameter("HIJRA_TODAY", HIJRA_TODAY);

    byte[] bytes = ReportViewer1.LocalReport.Render(
        "PDF", 
        null, 
        out mimeType, 
        out encoding, 
        out extension, 
        out streamIds, 
        out warnings);

    Response.Buffer = true;
    Response.Clear();
    Response.ContentType = mimeType;
    Response.AddHeader(
        "content-disposition", 
        "attachment; filename= filename" + "." + extension);
    Response.OutputStream.Write(bytes, 0, bytes.Length); // create the file  
    Response.Flush(); // send it to the client to download  
    Response.End();
}    

EDIT: If you're not stuck with Java <6 and speed is not critical and/or translation table is too limiting, use answer by David. The point is to use Normalizer (introduced in Java 6) instead of translation table inside the loop.

While this is not "perfect" solution, it works well when you know the range (in our case Latin1,2), worked before Java 6 (not a real issue though) and is much faster than the most suggested version (may or may not be an issue):

    /**
 * Mirror of the unicode table from 00c0 to 017f without diacritics.
 */
private static final String tab00c0 = "AAAAAAACEEEEIIII" +
    "DNOOOOO\u00d7\u00d8UUUUYI\u00df" +
    "aaaaaaaceeeeiiii" +
    "\u00f0nooooo\u00f7\u00f8uuuuy\u00fey" +
    "AaAaAaCcCcCcCcDd" +
    "DdEeEeEeEeEeGgGg" +
    "GgGgHhHhIiIiIiIi" +
    "IiJjJjKkkLlLlLlL" +
    "lLlNnNnNnnNnOoOo" +
    "OoOoRrRrRrSsSsSs" +
    "SsTtTtTtUuUuUuUu" +
    "UuUuWwYyYZzZzZzF";

/**
 * Returns string without diacritics - 7 bit approximation.
 *
 * @param source string to convert
 * @return corresponding string without diacritics
 */
public static String removeDiacritic(String source) {
    char[] vysl = new char[source.length()];
    char one;
    for (int i = 0; i < source.length(); i++) {
        one = source.charAt(i);
        if (one >= '\u00c0' && one <= '\u017f') {
            one = tab00c0.charAt((int) one - '\u00c0');
        }
        vysl[i] = one;
    }
    return new String(vysl);
}

Tests on my HW with 32bit JDK show that this performs conversion from àèélštc89FDC to aeelstc89FDC 1 million times in ~100ms while Normalizer way makes it in 3.7s (37x slower). In case your needs are around performance and you know the input range, this may be for you.

Enjoy :-)

That very well may be a false positive. Like the warning message says, it is common for a capture to start in the middle of a tcp session. In those cases it does not have that information. If you are really missing acks then it is time to start looking upstream from your host for where they are disappearing. It is possible that tshark can not keep up with the data and so it is dropping some metrics. At the end of your capture it will tell you if the "kernel dropped packet" and how many. By default tshark disables dns lookup, tcpdump does not. If you use tcpdump you need to pass in the "-n" switch. If you are having a disk IO issue then you can do something like write to memory /dev/shm. BUT be careful because if your captures get very large then you can cause your machine to start swapping.

My bet is that you have some very long running tcp sessions and when you start your capture you are simply missing some parts of the tcp session due to that. Having said that, here are some of the things that I have seen cause duplicate/missing acks.

1. Switches - (very unlikely but sometimes they get in a sick state)
2. Routers - more likely than switches, but not much
3. Firewall - More likely than routers. Things to look for here are resource exhaustion (license, cpu, etc)
4. Client side filtering software - antivirus, malware detection etc.

SQL keywords are case insensitive themselves.

Names of tables, columns etc, have a case sensitivity which is database dependent - you should probably assume that they are case sensitive unless you know otherwise (In many databases they aren't though; in MySQL table names are SOMETIMES case sensitive but most other names are not).

Comparing data using =, >, < etc, has a case awareness which is dependent on the collation settings which are in use on the individual database, table or even column in question. It's normal however, to keep collation fairly consistent within a database. We have a few columns which need to store case-sensitive values; they have a collation specifically set.

I assume that there exist some internal psql command for this, but you could also run the script command from util-linux-ng package:

DESCRIPTION Script makes a typescript of everything printed on your terminal.

You could use a List<T> and when T is a value type it will be allocated in contiguous memory which would not be the case if T is a reference type.

Example:

List<int> integers = new List<int>();
integers.Add(1);
integers.Add(4);
integers.Add(7);

int someElement = integers[1];

$dateTime = new DateTime('now', new DateTimeZone('Asia/Kolkata')); 
echo $dateTime->modify("+10 minutes")->format("H:i:s A");

IF YOU HAVE PEM FILE: In Eclipse go to Window > Preferences > Network Connections > SSH2, and then add path to your PEM file to "Private keys" and that should solve the problem.

FWIW, here's the dictionary thing. After setting a reference to MS Scripting. You can jack around with the array size of avInput to match your needs.

Sub somemacro()
Dim avInput As Variant
Dim uvals As Dictionary
Dim i As Integer
Dim rop As Range

avInput = Sheets("data").UsedRange
Set uvals = New Dictionary


For i = 1 To UBound(avInput, 1)
    If uvals.Exists(avInput(i, 1)) = False Then
        uvals.Add avInput(i, 1), 1
    Else
        uvals.Item(avInput(i, 1)) = uvals.Item(avInput(i, 1)) + 1
    End If
Next i

ReDim avInput(1 To uvals.Count)
i = 1

For Each kv In uvals.Keys
    avInput(i) = kv
    i = i + 1
Next kv

Set rop = Sheets("sheet2").Range("a1")
rop.Resize(UBound(avInput, 1), 1) = Application.Transpose(avInput)




End Sub

The origin of this error lies in the fact that each and every promise is expected to handle promise rejection i.e. have a .catch(...) . you can avoid the same by adding .catch(...) to a promise in the code as given below.

for example, the function PTest() will either resolve or reject a promise based on the value of a global variable somevar

var somevar = false;
var PTest = function () {
    return new Promise(function (resolve, reject) {
        if (somevar === true)
            resolve();
        else
            reject();
    });
}
var myfunc = PTest();
myfunc.then(function () {
     console.log("Promise Resolved");
}).catch(function () {
     console.log("Promise Rejected");
});

In some cases, the "unhandled promise rejection" message comes even if we have .catch(..) written for promises. It's all about how you write your code. The following code will generate "unhandled promise rejection" even though we are handling catch.

var somevar = false;
var PTest = function () {
    return new Promise(function (resolve, reject) {
        if (somevar === true)
            resolve();
        else
            reject();
    });
}
var myfunc = PTest();
myfunc.then(function () {
     console.log("Promise Resolved");
});
// See the Difference here
myfunc.catch(function () {
     console.log("Promise Rejected");
});

The difference is that you don't handle .catch(...) as chain but as separate. For some reason JavaScript engine treats it as promise without un-handled promise rejection.
