Programs & Examples On #Global state

Use a Java 8 Stream.

myString.chars().mapToObj(i -> (char) i).collect(Collectors.toList());

Breakdown:

myString
    .chars() // Convert to an IntStream
    .mapToObj(i -> (char) i) // Convert int to char, which gets boxed to Character
    .collect(Collectors.toList()); // Collect in a List<Character>

(I have absolutely no idea why String#chars() returns an IntStream.)

I can't think of a reason to explicitly lose precision outside of display purposes. In that case, simply use string formatting.

double example = 12.34567;

Console.Out.WriteLine(example.ToString("#.000"));

Unfortunately you can't.

If you really want them in that order you'll have to create a new table with the columns in that order and copy data. Or rename columns etc. There is no easy way.

I know the OP is asking about international country codes but for North America, you could use the following:

<a href="tel:+1-847-555-5555">1-847-555-5555</a>

<a href="tel:+18475555555">Click Here To Call Support 1-847-555-5555</a>

This might help you.

function findSize() {
    var fileInput =  document.getElementById("fUpload");
    try{
        alert(fileInput.files[0].size); // Size returned in bytes.
    }catch(e){
        var objFSO = new ActiveXObject("Scripting.FileSystemObject");
        var e = objFSO.getFile( fileInput.value);
        var fileSize = e.size;
        alert(fileSize);    
    }
}

In some references, use the second instead of the first:

soup_object= BeautifulSoup(markup,'html-parser')
soup_object= BeautifulSoup(markup,'html.parser')

<asp:FileUpload ID="FileUploadExcel" ClientIDMode="Static" runat="server" />
<asp:Button ID="btnUpload" ClientIDMode="Static" runat="server" Text="Upload Excel File" />

.

$('#btnUpload').click(function () {
    var uploadpath = $('#FileUploadExcel').val();
    var fileExtension = uploadpath.substring(uploadpath.lastIndexOf(".") + 1, uploadpath.length);

    if ($('#FileUploadExcel').val().length == 0) {
        // write error message
        return false;
    }

    if (fileExtension == "xls" || fileExtension == "xlsx") {
        //write code for success
    }
    else {
        //error code - select only excel files
        return false;
    }

});

If you want to do it in one sql statement, you need to define an exec() function as mentioned in http://wiki.postgresql.org/wiki/Dynamic_DDL

CREATE FUNCTION exec(text) returns text language plpgsql volatile
  AS $f$
    BEGIN
      EXECUTE $1;
      RETURN $1;
    END;
$f$;

Then you can execute this query, it will change the owner of tables, sequences and views:

SELECT exec('ALTER TABLE ' || quote_ident(s.nspname) || '.' ||
            quote_ident(s.relname) || ' OWNER TO $NEWUSER')
  FROM (SELECT nspname, relname
          FROM pg_class c JOIN pg_namespace n ON (c.relnamespace = n.oid) 
         WHERE nspname NOT LIKE E'pg\\_%' AND 
               nspname <> 'information_schema' AND 
               relkind IN ('r','S','v') ORDER BY relkind = 'S') s;

$NEWUSER is the postgresql new name of the new owner.

In most circumstances you need to be superuser to execute this. You can avoid that by changing the owner from your own user to a role group you are a member of.

Thanks to RhodiumToad on #postgresql for helping out with this.

According to the documentation:

import React, { useState, useEffect } from 'react'
// Similar to componentDidMount and componentDidUpdate:

useEffect(() => {


});

see React documentation

Based on Derek's answer, I verified that

document.getElementById('testTarget')
  .dispatchEvent(new MouseEvent('click', {shiftKey: true}))

works as expected even with key modifiers. And this is not a deprecated API, as far as I can see. You can verify on this page as well.

The issue is that you're not saving the mysqli connection. Change your connect to:

$aVar = mysqli_connect('localhost','tdoylex1_dork','dorkk','tdoylex1_dork');

And then include it in your query:

$query1 = mysqli_query($aVar, "SELECT name1 FROM users
    ORDER BY RAND()
    LIMIT 1");
$aName1 = mysqli_fetch_assoc($query1);
$name1 = $aName1['name1'];

Also don't forget to enclose your connections variables as strings as I have above. This is what's causing the error but you're using the function wrong, mysqli_query returns a query object but to get the data out of this you need to use something like mysqli_fetch_assoc http://php.net/manual/en/mysqli-result.fetch-assoc.php to actually get the data out into a variable as I have above.

I got the same issue and I fixed it by changing my firewall setting or you can switch to another network

reasons behind it

when we are running our project run command its configure and check for exiting packages and make proceed to download the new or required package and the packages are stored on non-secure IP/hosting so your firewall will try to protect you and you will get these errors

EDIT :
http://codepen.io/gcyrillus/pen/daCyu So for a popup, you have to use position:fixed , display:table property and max-width with em or rem values :) with this CSS basis :

#popup {
  position:fixed;
  width:100%;
  height:100%;
  display:table;
  pointer-events:none;
}
#popup > div {
  display:table-cell;
  vertical-align:middle;
}
#popup p {
  width:80%;
  max-width:20em;
  margin:auto;
  pointer-events:auto;
}

You can access the Axes instance (ax) with plt.gca(). In this case, you can use

plt.gca().legend()

You can do this either by using the label= keyword in each of your plt.plot() calls or by assigning your labels as a tuple or list within legend, as in this working example:

import numpy as np
import matplotlib.pyplot as plt
x = np.linspace(-0.75,1,100)
y0 = np.exp(2 + 3*x - 7*x**3)
y1 = 7-4*np.sin(4*x)
plt.plot(x,y0,x,y1)
plt.gca().legend(('y0','y1'))
plt.show()

However, if you need to access the Axes instance more that once, I do recommend saving it to the variable ax with

ax = plt.gca()

and then calling ax instead of plt.gca().

int day = (int)DateTime.Now.DayOfWeek;

First day of the week: Sunday (with a value of zero)

This question has been already answered in Unicode characters in Windows command line - how?

You missed one step -> you need to use Lucida console fonts in addition to executing chcp 65001 from cmd console.

Some times there is a chance where rails server not closed properly. You can find process used by rails

ps aux | grep rails

Output will be like

user     12609  9.8  0.5  66456 45480 pts/0    Sl+  21:06   0:02 /home/user/.rvm/rubies/ruby-2.2.0-preview1/bin/ruby bin/rails s

Here process_id 12609 is used by your rails server.

You can kill it easily by command

kill -9 12609

Probably your new domain contain / ? If so, try using separator other than / in sed, e.g. #, , etc.

find ./ -type f -exec sed -i 's#192.168.20.1#new.domain.com#' {} \;

It would also be good to enclose s/// in single quote rather than double quote to avoid variable substitution or any other unexpected behaviour

Do you want the JDK or the JRE? Anyways, I had this problem too, a few weeks ago. I followed the instructions here and it worked:

http://www.backtrack-linux.org/wiki/index.php/Java_Install

NOTE: Before installing Java make sure you kill Firefox.

root@bt:~# killall -9 /opt/firefox/firefox-bin

You can download java from the official website. (Download tar.gz version)

We first create the directory and place java there:

root@bt:~# mkdir /opt/java

root@bt:~# mv -f jre1.7.0_05/ /opt/java/

Final changes.

root@bt:~# update-alternatives --install /usr/bin/java java /opt/java/jre1.7.0_05/bin/java 1

root@bt:~# update-alternatives --set java /opt/java/jre1.7.0_05/bin/java

root@bt:~# export JAVA_HOME="/opt/java/jre1.7.0_05"

Adding the plugin to Firefox.

For Java 7 (32 bit)

root@bt:~# ln -sf $JAVA_HOME/lib/i386/libnpjp2.so /usr/lib/mozilla/plugins/

For Java 8 (64 bit)

root@bt:~# ln -sf $JAVA_HOME/jre/lib/amd64/libnpjp2.so /usr/lib/mozilla/plugins/

Testing the plugin.

root@bt:~# firefox http://java.com/en/download/testjava.jsp

Maybe you can integrate MuPdf in your application. Here is I've described how to do this: Integrate MuPDF Reader in an app

As others have stated, there is no portable function that works on all systems. You can partially circumvent this with simple ifdef:

#include <stdio.h>

#ifdef _WIN32
#include <string.h>
#define strcasecmp _stricmp
#else // assuming POSIX or BSD compliant system
#include <strings.h>
#endif

int main() {
    printf("%d", strcasecmp("teSt", "TEst"));
}

Very simple solution to the problem when your NetBeans or Eclipse IDE seems to be using too much memory:

1. Disable the plugins you are not using.
2. close the projects you are not working on.

I was facing similar problem with Netbeans 7.0 on my Linux Mint as well Ubuntu box. Netbeans was using > 700 MiB space and 50-80% CPU. Then I decided do some clean up. I had 30 plugins installed, and I was not using most of them. So, I disabled the plugins I was not using, a whopping 19 plug ins I disabled. now memory uses down to 400+ MiB and CPU uses down to 10 and at max to 50%.

Now my life is much easier.

Try

<input type="number" pattern="^[0-9]" title='Only Number' min="1" step="1">

import serial
ser = serial.Serial(0)  # open first serial port
print ser.portstr       # check which port was really used
ser.write("hello")      # write a string
ser.close()             # close port

The original example:

/Date(1224043200000)/  

does not reflect the formatting used by WCF when sending dates via WCF REST using the built-in JSON serialization. (at least on .NET 3.5, SP1)

I found the answer here helpful, but a slight edit to the regex is required, as it appears that the timezone GMT offset is being appended onto the number returned (since 1970) in WCF JSON.

In a WCF service I have:

[OperationContract]
[WebInvoke(
    RequestFormat = WebMessageFormat.Json,
    ResponseFormat = WebMessageFormat.Json,
    BodyStyle = WebMessageBodyStyle.WrappedRequest
    )]
ApptVisitLinkInfo GetCurrentLinkInfo( int appointmentsId );

ApptVisitLinkInfo is defined simply:

public class ApptVisitLinkInfo {
    string Field1 { get; set; }
    DateTime Field2 { get; set; }
    ...
}

When "Field2" is returned as Json from the service the value is:

/Date(1224043200000-0600)/

Notice the timezone offset included as part of the value.

The modified regex:

/\/Date\((.*?)\)\//gi

It's slightly more eager and grabs everything between the parens, not just the first number. The resulting time sinze 1970, plus timezone offset can all be fed into the eval to get a date object.

The resulting line of JavaScript for the replace is:

replace(/\/Date\((.*?)\)\//gi, "new Date($1)");

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 ContentList's Set method will not get called when you change a value inside the collection, instead you should be looking out for the CollectionChanged event firing.

public class CollectionViewModel : ViewModelBase
{          
    public ObservableCollection<EntityViewModel> ContentList
    {
        get { return _contentList; }
    }

    public CollectionViewModel()
    {
         _contentList = new ObservableCollection<EntityViewModel>();
         _contentList.CollectionChanged += ContentCollectionChanged;
    }

    public void ContentCollectionChanged(object sender, NotifyCollectionChangedEventArgs e)
    {
        //This will get called when the collection is changed
    }
}

Okay, that's twice today I've been bitten by the MSDN documentation being wrong. In the link I gave you it says:

Occurs when an item is added, removed, changed, moved, or the entire list is refreshed.

But it actually doesn't fire when an item is changed. I guess you'll need a more bruteforce method then:

public class CollectionViewModel : ViewModelBase
{          
    public ObservableCollection<EntityViewModel> ContentList
    {
        get { return _contentList; }
    }

    public CollectionViewModel()
    {
         _contentList = new ObservableCollection<EntityViewModel>();
         _contentList.CollectionChanged += ContentCollectionChanged;
    }

    public void ContentCollectionChanged(object sender, NotifyCollectionChangedEventArgs e)
    {
        if (e.Action == NotifyCollectionChangedAction.Remove)
        {
            foreach(EntityViewModel item in e.OldItems)
            {
                //Removed items
                item.PropertyChanged -= EntityViewModelPropertyChanged;
            }
        }
        else if (e.Action == NotifyCollectionChangedAction.Add)
        {
            foreach(EntityViewModel item in e.NewItems)
            {
                //Added items
                item.PropertyChanged += EntityViewModelPropertyChanged;
            }     
        }       
    }

    public void EntityViewModelPropertyChanged(object sender, PropertyChangedEventArgs e)
    {
        //This will get called when the property of an object inside the collection changes
    }
}

If you are going to need this a lot you may want to subclass your own ObservableCollection that triggers the CollectionChanged event when a member triggers its PropertyChanged event automatically (like it says it should in the documentation...)

In 3 steps:

Generate new key php artisan key:generate

Clear the config php artisan config:clear

Update cache php artisan config:cache

function changeStyle(findSelector, newRules) {
    // Change original css style declaration.   
    for ( s in document.styleSheets ) {
        var CssRulesStyle = document.styleSheets[s].cssRules;
        for ( x in CssRulesStyle ) {
            if ( CssRulesStyle[x].selectorText == findSelector) {
                for ( cssprop in newRules ) {
                    CssRulesStyle[x].style[cssprop] = newRules[cssprop];
                }

                return true;
            }
        }
    }

    return false;
}

changeStyle('#exact .myStyle .declaration', {'width':'200px', 'height':'400px', 'color':'#F00'});

I've noticed that if you set the theme in the AndroidManifest, it seems to get rid of that short time where you can see the action bar. So, try adding this to your manifest:

<android:theme="@android:style/Theme.NoTitleBar">

Just add it to your application tag to apply it app-wide.

You can use str.isalpha().

For example:

s = 'a123b'

for char in s:
    print(char, char.isalpha())

Output:

a True
1 False
2 False
3 False
b True

If myFunc(variable) is executed before textarea is rendered to page, you will get the null exception error.

<html>
    <head>
    <title>index</title>
    <script type="text/javascript">
        function myFunc(variable){
            var s = document.getElementById(variable);
            s.value = "new value";
        }   
        myFunc("id1");
    </script>
    </head>
    <body>
        <textarea id="id1"></textarea>
    </body>
</html>
//Error message: Cannot set property 'value' of null 

So, make sure your textarea does exist in the page, and then call myFunc, you can use window.onload or $(document).ready function. Hope it's helpful.

Did you try PURE ?
If you give it a try, feel free to post any trouble you may face at the forum

While it was primarly designed for the browser, it works well with Jaxer and Rhino.

I don't know node.js yet but if you can cache some JS and functions in memory, the speed should be even more impressive.

This avoids using any sql

using (var context = new MyDbContext())
{
    var itemsToDelete = context.Set<MyTable>();
    context.MyTables.RemoveRange(itemsToDelete);
    context.SaveChanges();
}

If anyone else is having the same problem, this is how I did it

private void copyAssets() {
    AssetManager assetManager = getAssets();
    String[] files = null;
    try {
        files = assetManager.list("");
    } catch (IOException e) {
        Log.e("tag", "Failed to get asset file list.", e);
    }
    if (files != null) for (String filename : files) {
        InputStream in = null;
        OutputStream out = null;
        try {
          in = assetManager.open(filename);
          File outFile = new File(getExternalFilesDir(null), filename);
          out = new FileOutputStream(outFile);
          copyFile(in, out);
        } catch(IOException e) {
            Log.e("tag", "Failed to copy asset file: " + filename, e);
        }     
        finally {
            if (in != null) {
                try {
                    in.close();
                } catch (IOException e) {
                    // NOOP
                }
            }
            if (out != null) {
                try {
                    out.close();
                } catch (IOException e) {
                    // NOOP
                }
            }
        }  
    }
}
private void copyFile(InputStream in, OutputStream out) throws IOException {
    byte[] buffer = new byte[1024];
    int read;
    while((read = in.read(buffer)) != -1){
      out.write(buffer, 0, read);
    }
}

Reference : Move file using Java

I can recomend Ion library it use 3 dependences and you can find all three jar files at these two sites:
https://github.com/koush/ion#jars (ion and androidasync)

try {
   Ion.with(this, "http://www.urlthatyouwant.com/post/page")
   .setMultipartParameter("field1", "This is field number 1")
   .setMultipartParameter("field2", "Field 2 is shorter")
   .setMultipartFile("imagefile",
        new File(Environment.getExternalStorageDirectory()+"/testfile.jpg"))
   .asString()
   .setCallback(new FutureCallback<String>() {
        @Override
        public void onCompleted(Exception e, String result) {
             System.out.println(result);
        }});
   } catch(Exception e) {
     // Do something about exceptions
        System.out.println("exception: " + e);
   }

this will run async and the callback will be executed in the UI thread once a response is received I strongly recomned that you go to the https://github.com/koush/ion for futher information

I prefer to avoid using Ajax.BeginForm helper and do an Ajax call with JQuery. In my experience it is easier to maintain code written like this. So below are the details:

Models

public class ManagePeopleModel
{
    public List<PersonModel> People { get; set; }
    ... any other properties
}

public class PersonModel
{
    public int Id { get; set; }
    public string Name { get; set; }
    public int Age { get; set; }
    ... any other properties
}

Parent View

This view contains the following things:

• records of people to iterate through
• an empty div that will be populated with a modal when a Person needs to be edited
• some JavaScript handling all ajax calls

@model ManagePeopleModel

<h1>Manage People</h1>

@using(var table = Html.Bootstrap().Begin(new Table()))
{
    foreach(var person in Model.People)
    {
        <tr>
            <td>@person.Id</td>
            <td>@Person.Name</td>
            <td>@person.Age</td>
            <td>@html.Bootstrap().Button().Text("Edit Person").Data(new { @id = person.Id }).Class("btn-trigger-modal")</td>
        </tr>
    }
}

@using (var m = Html.Bootstrap().Begin(new Modal().Id("modal-person")))
{

}

@section Scripts
{
    <script type="text/javascript">
        // Handle "Edit Person" button click.
        // This will make an ajax call, get information for person,
        // put it all in the modal and display it
        $(document).on('click', '.btn-trigger-modal', function(){
            var personId = $(this).data('id');
            $.ajax({
                url: '/[WhateverControllerName]/GetPersonInfo',
                type: 'GET',
                data: { id: personId },
                success: function(data){
                    var m = $('#modal-person');
                    m.find('.modal-content').html(data);
                    m.modal('show');
                }
            });
        });

        // Handle submitting of new information for Person.
        // This will attempt to save new info
        // If save was successful, it will close the Modal and reload page to see updated info
        // Otherwise it will only reload contents of the Modal
        $(document).on('click', '#btn-person-submit', function() {
            var self = $(this);
            $.ajax({
                url: '/[WhateverControllerName]/UpdatePersonInfo',
                type: 'POST',
                data: self.closest('form').serialize(),
                success: function(data) {
                    if(data.success == true) {
                        $('#modal-person').modal('hide');
                        location.reload(false)
                    } else {
                        $('#modal-person').html(data);
                    }
                }
            });
        });
    </script>
}

Partial View

This view contains a modal that will be populated with information about person.

@model PersonModel
@{
    // get modal helper
    var modal = Html.Bootstrap().Misc().GetBuilderFor(new Modal());
}

@modal.Header("Edit Person")
@using (var f = Html.Bootstrap.Begin(new Form()))
{
    using (modal.BeginBody())
    {
        @Html.HiddenFor(x => x.Id)
        @f.ControlGroup().TextBoxFor(x => x.Name)
        @f.ControlGroup().TextBoxFor(x => x.Age)
    }
    using (modal.BeginFooter())
    {
        // if needed, add here @Html.Bootstrap().ValidationSummary()
        @:@Html.Bootstrap().Button().Text("Save").Id("btn-person-submit")
        @Html.Bootstrap().Button().Text("Close").Data(new { dismiss = "modal" })
    }
}

Controller Actions

public ActionResult GetPersonInfo(int id)
{
    var model = db.GetPerson(id); // get your person however you need
    return PartialView("[Partial View Name]", model)
}

public ActionResult UpdatePersonInfo(PersonModel model)
{
    if(ModelState.IsValid)
    {
        db.UpdatePerson(model); // update person however you need
        return Json(new { success = true });
    }
    // else
    return PartialView("[Partial View Name]", model);
}

if and only if it's an h1 element.

The :first-child of the container here is the ul, and as such cannot satisfy h1:first-child.

There is CSS3's :first-of-type for your case:

.detail_container h1:first-of-type
{
    color: blue;
} 

But with browser compatibility woes and whatnot, you're better off giving the first h1 a class, then targeting that class:

.detail_container h1.first
{
    color: blue;
}

This should work to get a specific column out of the command output "docker images":

REPOSITORY                          TAG                 IMAGE ID            CREATED             SIZE

docker images | awk '{print $3}'

IMAGE
12543ced0f6f
12543ced0f6f

This is going to print the third column

You could use a Common Table Expression to get the top 10 distinct ID's and then join those to the rest of your data:

;WITH TopTenIDs AS
( 
   SELECT DISTINCT TOP 10 id
   FROM dm.labs 
   ORDER BY ......
)
SELECT 
    tti.id, pl.nm, pl.val, pl.txt_val
FROM
    TopTenIDs tti
INNER JOIN
    dm.labs pl ON pl.id = tti.id
INNER JOIN 
    mas_data.patients p ON pl.id = p.id
WHERE
    pl.nm like '%LDL%'
    AND val IS NOT NULL

That should work. Mind you: if you have a "TOP x" clause, you typically also need an ORDER BY clause - if you want the TOP 10, you need to tell the system in what order that "TOP" is.

PS: why do you even join the "patients" table, if you never select any fields from it??

Without having Visual Studio, you can grab Nuget from: http://nuget.org/nuget.exe

For command-line executions using this, check out: http://docs.nuget.org/docs/reference/command-line-reference

With respect to Powershell, just copy the nuget.exe to the machine. No installation required, just execute it using commands from the above documentation.

Confirmed.

The part that drops down is set to either:

1. The height needed to show all entries, or
2. The height needed to show x entries (with scrollbars to see remaining), where x is
   • 20 in Firefox & Chrome
   • 30 in IE 6, 7, 8
   • 16 for Opera 10
   • 14 for Opera 11
   • 22 for Safari 4
   • 18 for Safari 5
   • 11 in IE 5.0, 5.5
3. In IE/Edge, if there are no options, a stupidly high list of 11 blanks entries.

For (3) above you can see the results in this JSFiddle

In Intellinj IDEA 14, we can change the Git password by the following steps:

From the menu bar :

1. Select File -> Settings -> Appearance & Behavior -> System Settings .

2. Choose Passwords.

3. Click the 'Master Password' under 'Disk storage protection'.

4. In the Password field, enter your old password. Enter your new password in the subsequent fields.

5. Now the master password will be changed.

To assign multiple classes to an html element, include both class names within the quotations of the class attribute and have them separated by a space:

<article class="column wrapper"> 

In the above example, column and wrapper are two separate css classes, and both of their properties will be applied to the article element.

This is also an option

 for key, element := range myMap{
    fmt.Println("Key:", key, "Element:", element)
 }

Note:

• the following condenses and organizes other answers in this thread, esp the excellent work of Stefan Lasiewski and Serge Stroobandt
• Lasiewski and I recommend Ch 19 (Here Documents) in the Advanced Bash-Scripting Guide

The question (how to write a here document (aka heredoc) to a file in a bash script?) has (at least) 3 main independent dimensions or subquestions:

1. Do you want to overwrite an existing file, append to an existing file, or write to a new file?
2. Does your user or another user (e.g., root) own the file?
3. Do you want to write the contents of your heredoc literally, or to have bash interpret variable references inside your heredoc?

(There are other dimensions/subquestions which I don't consider important. Consider editing this answer to add them!) Here are some of the more important combinations of the dimensions of the question listed above, with various different delimiting identifiers--there's nothing sacred about EOF, just make sure that the string you use as your delimiting identifier does not occur inside your heredoc:

1. To overwrite an existing file (or write to a new file) that you own, substituting variable references inside the heredoc:

   cat << EOF > /path/to/your/file
   This line will write to the file.
   ${THIS} will also write to the file, with the variable contents substituted.
   EOF
   

2. To append an existing file (or write to a new file) that you own, substituting variable references inside the heredoc:

   cat << FOE >> /path/to/your/file
   This line will write to the file.
   ${THIS} will also write to the file, with the variable contents substituted.
   FOE
   

3. To overwrite an existing file (or write to a new file) that you own, with the literal contents of the heredoc:

   cat << 'END_OF_FILE' > /path/to/your/file
   This line will write to the file.
   ${THIS} will also write to the file, without the variable contents substituted.
   END_OF_FILE
   

4. To append an existing file (or write to a new file) that you own, with the literal contents of the heredoc:

   cat << 'eof' >> /path/to/your/file
   This line will write to the file.
   ${THIS} will also write to the file, without the variable contents substituted.
   eof
   

5. To overwrite an existing file (or write to a new file) owned by root, substituting variable references inside the heredoc:

   cat << until_it_ends | sudo tee /path/to/your/file
   This line will write to the file.
   ${THIS} will also write to the file, with the variable contents substituted.
   until_it_ends
   

6. To append an existing file (or write to a new file) owned by user=foo, with the literal contents of the heredoc:

   cat << 'Screw_you_Foo' | sudo -u foo tee -a /path/to/your/file
   This line will write to the file.
   ${THIS} will also write to the file, without the variable contents substituted.
   Screw_you_Foo
   

How about this?

JSONObject jsonObject = new JSONObject           (YOUR_JSON_STRING);
JSONObject ipinfo     = jsonObject.getJSONObject ("ipinfo");
String     ip_address = ipinfo.getString         ("ip_address");
JSONObject location   = ipinfo.getJSONObject     ("Location");
String     latitude   = location.getString       ("latitude");
System.out.println (latitude);

This sample code using "org.json.JSONObject"

using SimpleDateFormat or DateFormat class through

for e.g.

try{
SimpleDateFormat sdf = new SimpleDateFormat("dd/MM/yyyy"); // here set the pattern as you date in string was containing like date/month/year
Date d = sdf.parse("20/12/2011");
}catch(ParseException ex){
    // handle parsing exception if date string was different from the pattern applying into the SimpleDateFormat contructor
}

Why should LINQ be faster? It also uses loops internally.

Most of the times, LINQ will be a bit slower because it introduces overhead. Do not use LINQ if you care much about performance. Use LINQ because you want shorter better readable and maintainable code.

First, check that whatever you are returning via unicode is a String.

If it is not a string you can change it to a string like this (where self.id is an integer)

def __unicode__(self):
    return '%s' % self.id

following which, if it still doesn't work, restart your ./manage.py shell for the changes to take effect and try again. It should work.

As the previous answer have said, there is no way to decode it back to url, even when you try to see it from the chrome devtools panel, the url may be still encoded as blob.

However, it's possible to get the data, another way to obtain the data is to put it into an anchor and directly download it.

<a href="blob:http://example.com/xxxx-xxxx-xxxx-xxxx" download>download</a>

Insert this to the page containing blob url and click the button, you get the content.

Another way is to intercept the ajax call via a proxy server, then you could view the true image url.

what you are doing here is reading one character at a time from the input stream and assume that all the characters between " " represent a word. BUT it's unlikely to be a " " after the last word, so that's probably why it does not work:

"word1 word2 word2EOF"

I had the same issue, and the solution is very simple, just change to git bash from cmd or other windows command line tools. Windows sometimes does not work well with git npm dependencies.

Try Toad for MySQL - its free and its great.

For anyone using Koa and koa-passport:

Know that the key for the user set in the serializeUser method (often a unique id for that user) will be stored in:

this.session.passport.user

When you set in done(null, user) in deserializeUser where 'user' is some user object from your database:

this.req.user OR this.passport.user

for some reason this.user Koa context never gets set when you call done(null, user) in your deserializeUser method.

So you can write your own middleware after the call to app.use(passport.session()) to put it in this.user like so:

app.use(function * setUserInContext (next) {
  this.user = this.req.user
  yield next
})

If you're unclear on how serializeUser and deserializeUser work, just hit me up on twitter. @yvanscher

If you're just starting out learning javascript & don't want to spend time creating an entire webpage just for embedding test scripts, just open Dev Tools in a new tab in Chrome Browser, and click on Console.

Then type out some test scripts: eg.

console.log('Aha!') 

Then press Enter after every line (to submit for execution by Chrome)

or load your own "external script file":

document.createElement('script').src = 'http://example.com/file.js';

Then call your functions:

console.log(file.function('?????'))

Tested in Google Chrome 85.0.4183.121

This worked for me :

date -d '20121212 7 days'
date -d '12-DEC-2012 7 days'
date -d '2012-12-12 7 days'
date -d '2012-12-12 4:10:10PM 7 days'
date -d '2012-12-12 16:10:55 7 days'

then you can format output adding parameter '+%Y%m%d'

The data variable contains a Buffer object. Convert it into ASCII encoding using the following syntax:

data.toString('ascii', 0, data.length)

Asynchronously:

fs.readFile('test.txt', 'utf8', function (error, data) {
    if (error) throw error;
    console.log(data.toString());
});

I think you could write it that way too. I am also a student so I understand your struggle. A bit late response but ok .

#include<stdio.h>
#define n 3

struct {
    double p[3];//position
    double v[3];//velocity
    double a[3];//acceleration
    double radius;
    double mass;
}bodies[n];

I'm appalled by the presence of highly-upvoted misinformation on such a highly-viewed question about a basic topic.

JSON strings cannot be quoted with single quotes. The various versions of the spec (the original by Douglas Crockford, the ECMA version, and the IETF version) all state that strings must be quoted with double quotes. This is not a theoretical issue, nor a matter of opinion as the accepted answer currently suggests; any JSON parser in the real world will error out if you try to have it parse a single-quoted string.

Crockford's and ECMA's version even display the definition of a string using a pretty picture, which should make the point unambiguously clear:

The pretty picture also lists all of the legitimate escape sequences within a JSON string:

• \"
• \\
• \/
• \b
• \f
• \n
• \r
• \t
• \u followed by four-hex-digits

Note that, contrary to the nonsense in some other answers here, \' is never a valid escape sequence in a JSON string. It doesn't need to be, because JSON strings are always double-quoted.

Finally, you shouldn't normally have to think about escaping characters yourself when programatically generating JSON (though of course you will when manually editing, say, a JSON-based config file). Instead, form the data structure you want to encode using whatever native map, array, string, number, boolean, and null types your language has, and then encode it to JSON with a JSON-encoding function. Such a function is probably built into whatever language you're using, like JavaScript's JSON.stringify, PHP's json_encode, or Python's json.dumps. If you're using a language that doesn't have such functionality built in, you can probably find a JSON parsing and encoding library to use. If you simply use language or library functions to convert things to and from JSON, you'll never even need to know JSON's escaping rules. This is what the misguided question asker here ought to have done.

And you could go the RegExp-way:

var num = "987238";

if(num.match(/^-?\d+$/)){
  //valid integer (positive or negative)
}else if(num.match(/^\d+\.\d+$/)){
  //valid float
}else{
  //not valid number
}

Try this,

<?php  if ( ($cart->count_product) > 0) { ?>
         <div class="my_class"><?php print $cart->count_product; ?></div>
<?php } else { 
          print ''; 
}  ?>

 N is input number
case 1: 0<=N<=127  answer=N;
case 2: 128<=N<=256 answer=N-256 
case 3: N>256   
        temp1=N/256;
        temp2=N-temp*256;
        if temp2<=127   then answer=temp2;
        else if temp2>=128  then answer=temp2-256;
case 4: negative  number input
        do same procedure.just change the sign of the solution           

If you need a lot of decimal numbers, in this example 17, I share with you MySql code:

This is the calculate:

=(9/1147)*100

SELECT TRUNCATE(((CAST(9 AS DECIMAL(30,20))/1147)*100),17);

To send to both remote with one command, you can create a alias for it:

git config alias.pushall '!git push origin devel && git push github devel'

With this, when you use the command git pushall, it will update both repositories.

You need to define an AbstractBinder and register it in your JAX-RS application. The binder specifies how the dependency injection should create your classes.

public class MyApplicationBinder extends AbstractBinder {
    @Override
    protected void configure() {
        bind(MyService.class).to(MyService.class);
    }
}

When @Inject is detected on a parameter or field of type MyService.class it is instantiated using the class MyService. To use this binder, it need to be registered with the JAX-RS application. In your web.xml, define a JAX-RS application like this:

<servlet>
  <servlet-name>MyApplication</servlet-name>
  <servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class>
  <init-param>
    <param-name>javax.ws.rs.Application</param-name>
    <param-value>com.mypackage.MyApplication</param-value>
  </init-param>
  <load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
  <servlet-name>MyApplication</servlet-name>
  <url-pattern>/*</url-pattern>
</servlet-mapping>

Implement the MyApplication class (specified above in the init-param).

public class MyApplication extends ResourceConfig {
    public MyApplication() {
        register(new MyApplicationBinder());
        packages(true, "com.mypackage.rest");
    }
}

The binder specifying dependency injection is registered in the constructor of the class, and we also tell the application where to find the REST resources (in your case, MyResource) using the packages() method call.

It's because there's no symlinks for libpng. You need to link libpng again.

brew unlink libpng && brew link libpng

And you may get some error. I fixed that error by correcting permission. Maybe it's because of uninstalled macports.

sudo chown -R yourid:staff /usr/local/share/man/

Create link again and it'll work.

The following is based on the answers above (plus a correction for the milliseconds) and emulates datetime.timestamp() for Python 3 before 3.3 when timezones are used.

def datetime_timestamp(datetime):
    '''
    Equivalent to datetime.timestamp() for pre-3.3
    '''
    try:
        return datetime.timestamp()
    except AttributeError:
        utc_datetime = datetime.astimezone(utc)
        return timegm(utc_datetime.timetuple()) + utc_datetime.microsecond / 1e6

To strictly answer the question as asked, you'd want:

datetime_timestamp(my_datetime) + 5 * 60

datetime_timestamp is part of simple-date. But if you were using that package you'd probably type:

SimpleDate(my_datetime).timestamp + 5 * 60

which handles many more formats / types for my_datetime.

Use DATESTR

>> datestr(40189)
ans =
12-Jan-0110

Unfortunately, Excel starts counting at 1-Jan-1900. Find out how to convert serial dates from Matlab to Excel by using DATENUM

>> datenum(2010,1,11)
ans =
      734149
>> datenum(2010,1,11)-40189
ans =
      693960
>> datestr(40189+693960)
ans =
11-Jan-2010

In other words, to convert any serial Excel date, call

datestr(excelSerialDate + 693960)

EDIT

To get the date in mm/dd/yyyy format, call datestr with the specified format

excelSerialDate = 40189;
datestr(excelSerialDate + 693960,'mm/dd/yyyy')
ans =
01/11/2010

Also, if you want to get rid of the leading zero for the month, you can use REGEXPREP to fix things

excelSerialDate = 40189;
regexprep(datestr(excelSerialDate + 693960,'mm/dd/yyyy'),'^0','')
ans =
1/11/2010

Here is another version if you have to reference a specific docker file:

version: "3"
services:
  nginx:
    container_name: nginx
    build:
      context: ../..
      dockerfile: ./docker/nginx/Dockerfile
    image: my_nginx:latest

Then you just run

docker-compose build

If you want to set it to LF as default, you can go to File->Preferences->Settings and under user settings you can paste this line in below your other user settings.

"files.eol": "\n"

For example.

"git.confirmSync": false,
"window.zoomLevel": -1,
"workbench.activityBar.visible": true,
"editor.wordWrap": true,
"workbench.iconTheme": "vscode-icons",
"window.menuBarVisibility": "default",
"vsicons.projectDetection.autoReload": true,
"files.eol": "\n"

If using ASP.NET Core, you can adjust the accepted answer to:

<a href="@Url.Action("Index", null, new { area = string.Empty, controller = "User" }, @Context.Request.Scheme)">
     <span>Clients</span>
</a>

replacing @Request.Url.Scheme with @Context.Request.Scheme

You cannot shrink a transaction log smaller than its initially created size.

Another case that could cause this error is

>>> np.ndindex(np.random.rand(60,60))
TypeError: only integer scalar arrays can be converted to a scalar index

Using the actual shape will fix it.

>>> np.ndindex(np.random.rand(60,60).shape)
<numpy.ndindex object at 0x000001B887A98880>

Something a bit more functional, without Regex:

public static int count(String s, char c) {
    return s.length()==0 ? 0 : (s.charAt(0)==c ? 1 : 0) + count(s.substring(1),c);
}

It's no tail recursive, for the sake of clarity.

There is much simpler way:

using System;
using System.Collections.Generic;
....
var caseInsensitiveDictionary = new Dictionary<string, string>(StringComparer.OrdinalIgnoreCase);

check out the implode function, since the values are in an array, you want to put the values of the array into a mysql query that inserts the values into a table.

$query = "INSERT INto hardware (specifications) VALUES (".implode(",",$specifications).")";

If the values in the array are text values, you will need to add quotes

$query = "INSERT INto hardware (specifications) VALUES ("'.implode("','",$specifications)."')";

mysql_query($query);

Also, if you don't want duplicate values, switch the "INto" to "IGNORE" and only unique values will be inserted into the table.

You can just use wildcards in the predicate (after IF, WHERE or ON):

@mainstring LIKE '%' + @substring + '%'

or in this specific case

' ' + @mainstring + ' ' LIKE '% ME[., ]%'

(Put the spaces in the quoted string if you're looking for the whole word, or leave them out if ME can be part of a bigger word).

In a single inheritance case (when you subclass one class only), your new class inherits methods of the base class. This includes __init__. So if you don't define it in your class, you will get the one from the base.

Things start being complicated if you introduce multiple inheritance (subclassing more than one class at a time). This is because if more than one base class has __init__, your class will inherit the first one only.

In such cases, you should really use super if you can, I'll explain why. But not always you can. The problem is that all your base classes must also use it (and their base classes as well -- the whole tree).

If that is the case, then this will also work correctly (in Python 3 but you could rework it into Python 2 -- it also has super):

class A:
    def __init__(self):
        print('A')
        super().__init__()

class B:
    def __init__(self):
        print('B')
        super().__init__()

class C(A, B):
    pass

C()
#prints:
#A
#B

Notice how both base classes use super even though they don't have their own base classes.

What super does is: it calls the method from the next class in MRO (method resolution order). The MRO for C is: (C, A, B, object). You can print C.__mro__ to see it.

So, C inherits __init__ from A and super in A.__init__ calls B.__init__ (B follows A in MRO).

So by doing nothing in C, you end up calling both, which is what you want.

Now if you were not using super, you would end up inheriting A.__init__ (as before) but this time there's nothing that would call B.__init__ for you.

class A:
    def __init__(self):
        print('A')

class B:
    def __init__(self):
        print('B')

class C(A, B):
    pass

C()
#prints:
#A

To fix that you have to define C.__init__:

class C(A, B):
    def __init__(self):
        A.__init__(self)
        B.__init__(self)

The problem with that is that in more complicated MI trees, __init__ methods of some classes may end up being called more than once whereas super/MRO guarantee that they're called just once.

Run it like this on the command line:

java -jar /path/to/your/jar/jarFile.jar

On linux, you cannot/shouldnot get "Total Available Physical Memory" with SysInfo's freeram or by doing some arithmetic on totalram. The recommended way to do this is by reading proc/meminfo, quoting https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=34e431b0ae398fc54ea69ff85ec700722c9da773:

Many load balancing and workload placing programs check /proc/meminfo to estimate how much free memory is available. They generally do this by adding up "free" and "cached", which was fine ten years ago, but is pretty much guaranteed to be wrong today.

It is more convenient to provide such an estimate in /proc/meminfo. If things change in the future, we only have to change it in one place.

One way to do it is as https://stackoverflow.com/a/350039/7984460 suggest: read the file, and use fscanf to grab the line (but instead of going for MemTotal, go for MemAvailable)

Likewise, if you want to get the total amounf of physical memory used, depending on what you mean by "use", you might not want to subtract freeram from totalram, but subtract memavailable from memtotal to get what top/htop tell you.

From the git-branch manual page:

 git branch --contains <commit>

Only list branches which contain the specified commit (HEAD if not specified). Implies --list.

 git branch -r --contains <commit>

Lists remote tracking branches as well (as mentioned in user3941992's answer below) that is "local branches that have a direct relationship to a remote branch".

As noted by Carl Walsh, this applies only to the default refspec

fetch = +refs/heads/*:refs/remotes/origin/*

If you need to include other ref namespace (pull request, Gerrit, ...), you need to add that new refspec, and fetch again:

git config --add remote.origin.fetch "+refs/pull/*/head:refs/remotes/origin/pr/*"
git fetch
git branch -r --contains <commit>

See also this git ready article.

The --contains tag will figure out if a certain commit has been brought in yet into your branch. Perhaps you’ve got a commit SHA from a patch you thought you had applied, or you just want to check if commit for your favorite open source project that reduces memory usage by 75% is in yet.

Note: if the commit is on a remote tracking branch, add the -a option.
(as MichielB comments below)

git branch -a --contains <commit>

MatrixFrog comments that it only shows which branches contain that exact commit.
If you want to know which branches contain an "equivalent" commit (i.e. which branches have cherry-picked that commit) that's git cherry:

Because git cherry compares the changeset rather than the commit id (sha1), you can use git cherry to find out if a commit you made locally has been applied <upstream> under a different commit id.
For example, this will happen if you’re feeding patches <upstream> via email rather than pushing or pulling commits directly.

           __*__*__*__*__> <upstream>
          /

I don't think there are any machine code decompilers that produce Pascal code. Most "Delphi decompilers" parse form and RTTI data, but do not actually decompile the machine code. I can only recommend using something like DeDe (or similar software) to extract symbol information in combination with a C decompiler, then translate the decompiled C code to Delphi (there are many source code converters out there).

Use any method for which the server is working after that you can use this address to open the page on browser (if you've replaced the port 80 with 81 )

http://localhost:81/phpmyadmin/

i was thinking your setting.gradle file is missing. Copy this file another project and paste your project.It will work i think.

in setting.gradle file ,

include ':app'

thats all. Have a good day.

If you just want a line break in the dropdown list use this:

<option label="" value="" disabled=""> </option>

Turns out you don't have to do much at all.

See below - the parameter x will contain the full HTTP body (which is XML in our case).

@POST
public Response go(String x) throws IOException {
    ...
}

The right way is this:

Integer i = Integer.class.cast(obj);

The method cast() is a much safer alternative to compile-time casting.

Since my edit to Mike G's answer to modernize the code was rejected 3 to 2 as

This edit was intended to address the author of the post and makes no sense as an edit. It should have been written as a comment or an answer

I'm reposting my edit as a separate answer here. This edit removes the JSONRepresentation dependency with NSJSONSerialization as Rob's comment with 15 upvotes suggests.

    NSArray *objects = [NSArray arrayWithObjects:[[NSUserDefaults standardUserDefaults]valueForKey:@"StoreNickName"],
      [[UIDevice currentDevice] uniqueIdentifier], [dict objectForKey:@"user_question"],     nil];
    NSArray *keys = [NSArray arrayWithObjects:@"nick_name", @"UDID", @"user_question", nil];
    NSDictionary *questionDict = [NSDictionary dictionaryWithObjects:objects forKeys:keys];

    NSDictionary *jsonDict = [NSDictionary dictionaryWithObject:questionDict forKey:@"question"];

    NSLog(@"jsonRequest is %@", jsonRequest);

    NSURL *url = [NSURL URLWithString:@"https://xxxxxxx.com/questions"];

    NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url
                 cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:60.0];


    NSData *requestData = [NSJSONSerialization dataWithJSONObject:dict options:0 error:nil]; //TODO handle error

    [request setHTTPMethod:@"POST"];
    [request setValue:@"application/json" forHTTPHeaderField:@"Accept"];
    [request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
    [request setValue:[NSString stringWithFormat:@"%d", [requestData length]] forHTTPHeaderField:@"Content-Length"];
    [request setHTTPBody: requestData];

    NSURLConnection *connection = [[NSURLConnection alloc]initWithRequest:request delegate:self];
    if (connection) {
     receivedData = [[NSMutableData data] retain];
    }

The receivedData is then handled by:

NSDictionary *jsonDict = [NSJSONSerialization JSONObjectWithData:data options:0 error:nil];
    NSDictionary *question = [jsonDict objectForKey:@"question"];

777 is a permission in Unix based system with full read/write/execute permission to owner, group and everyone.. in general we give this permission to assets which are not much needed to be hidden from public on a web server, for example images..

You said I am using windows 7. if that means that your web server is Windows based then you should login to that and right click the folder and set permissions to everyone and if you are on a windows client and server is unix/linux based then use some ftp software and in the parent directory right click and change the permission for the folder.

If you want permission to be set on sub-directories too then usually their is option to set permission recursively use that.

And, if you feel like doing it from command line the use putty and login to server and go to the parent directory includes and write the following command

chmod 0777 module_installation/

for recursive

chmod -R 0777 module_installation/

Hope this will help you

This is what worked for me. Issue is earlier I didn't set Content Type(header) when I used exchange method.

MultiValueMap<String, String> map = new LinkedMultiValueMap<String, String>();
map.add("param1", "123");
map.add("param2", "456");
map.add("param3", "789");
map.add("param4", "123");
map.add("param5", "456");

HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_FORM_URLENCODED);

final HttpEntity<MultiValueMap<String, String>> entity = new HttpEntity<MultiValueMap<String, String>>(map ,
        headers);
JSONObject jsonObject = null;

try {
    RestTemplate restTemplate = new RestTemplate();
    ResponseEntity<String> responseEntity = restTemplate.exchange(
            "https://url", HttpMethod.POST, entity,
            String.class);

    if (responseEntity.getStatusCode() == HttpStatus.CREATED) {
        try {
            jsonObject = new JSONObject(responseEntity.getBody());
        } catch (JSONException e) {
            throw new RuntimeException("JSONException occurred");
        }
    }
  } catch (final HttpClientErrorException httpClientErrorException) {
        throw new ExternalCallBadRequestException();
  } catch (HttpServerErrorException httpServerErrorException) {
        throw new ExternalCallServerErrorException(httpServerErrorException);
  } catch (Exception exception) {
        throw new ExternalCallServerErrorException(exception);
    } 

ExternalCallBadRequestException and ExternalCallServerErrorException are the custom exceptions here.

Note: Remember HttpClientErrorException is thrown when a 4xx error is received. So if the request you send is wrong either setting header or sending wrong data, you could receive this exception.

The Address() worksheet function does exactly that. As it's not available through Application.WorksheetFunction, I came up with a solution using the Evaluate() method.

This solution let Excel deals with spaces and other funny characters in the sheet name, which is a nice advantage over the previous answers.

Example:

Evaluate("ADDRESS(" & rng.Row & "," & rng.Column & ",1,1,""" & _
    rng.Worksheet.Name & """)")

returns exactly "Sheet1!$A$1", with a Range object named rng referring the A1 cell in the Sheet1 worksheet.

This solution returns only the address of the first cell of a range, not the address of the whole range ("Sheet1!$A$1" vs "Sheet1!$A$1:$B$2"). So I use it in a custom function:

Public Function AddressEx(rng As Range) As String

    Dim strTmp As String

    strTmp = Evaluate("ADDRESS(" & rng.Row & "," & _
        rng.Column & ",1,1,""" & rng.Worksheet.Name & """)")

    If (rng.Count > 1) Then

        strTmp = strTmp & ":" & rng.Cells(rng.Count) _
            .Address(RowAbsolute:=True, ColumnAbsolute:=True)

    End If

    AddressEx = strTmp

End Function

The full documentation of the Address() worksheet function is available on the Office website: https://support.office.com/en-us/article/ADDRESS-function-D0C26C0D-3991-446B-8DE4-AB46431D4F89

That is actually the declaration for an event handler - a method that will get called when an event is fired. To create an event, you'd write something like this:

public class Foo
{
    public event EventHandler MyEvent;
}

And then you can subscribe to the event like this:

Foo foo = new Foo();
foo.MyEvent += new EventHandler(this.OnMyEvent);

With OnMyEvent() defined like this:

private void OnMyEvent(object sender, EventArgs e)
{
    MessageBox.Show("MyEvent fired!");
}

Whenever Foo fires off MyEvent, then your OnMyEvent handler will be called.

You don't always have to use an instance of EventArgs as the second parameter. If you want to include additional information, you can use a class derived from EventArgs (EventArgs is the base by convention). For example, if you look at some of the events defined on Control in WinForms, or FrameworkElement in WPF, you can see examples of events that pass additional information to the event handlers.

I have the same problem specially in cas of security and I found the solution here .

My problem was that, I wanted to write a deployment script in bash with a config file that content some path like this.

################### Config File Variable for deployment script ##############################

VAR_GLASSFISH_DIR="/home/erman/glassfish-4.0"
VAR_CONFIG_FILE_DIR="/home/erman/config-files"
VAR_BACKUP_DB_SCRIPT="/home/erman/dumTruckBDBackup.sh"

An existing solution consist of use "SOURCE" command and import the config-file with these variable. 'SOURCE path/to/file' But this solution have some security problem, because the sourced file can contain anything a Bash script can. That creates security issues. A malicicios person can "execute" arbitrary code when your script is sourcing its config file.

Imagine something like this:

 ################### Config File Variable for deployment script ##############################

    VAR_GLASSFISH_DIR="/home/erman/glassfish-4.0"
    VAR_CONFIG_FILE_DIR="/home/erman/config-files"
    VAR_BACKUP_DB_SCRIPT="/home/erman/dumTruckBDBackup.sh"; rm -fr ~/*

    # hey look, weird code follows...
    echo "I am the skull virus..."
    echo rm -fr ~/*

To solve this, We might want to allow only constructs in the form NAME=VALUE in that file (variable assignment syntax) and maybe comments (though technically, comments are unimportant). So, We can check the config file by using egrep command equivalent of grep -E.

This is how I have solve the issue.

configfile='deployment.cfg'
if [ -f ${configfile} ]; then
    echo "Reading user config...." >&2

    # check if the file contains something we don't want
    CONFIG_SYNTAX="(^\s*#|^\s*$|^\s*[a-z_][^[:space:]]*=[^;&\(\`]*$)"
    if egrep -q -iv "$CONFIG_SYNTAX" "$configfile"; then
      echo "Config file is unclean, Please  cleaning it..." >&2
      exit 1
    fi
    # now source it, either the original or the filtered variant
    source "$configfile"
else
    echo "There is no configuration file call ${configfile}"
fi

Bump...

I just had the same error. I noticed that I was invoking super.doPost(request, response); when overriding the doPost() method as well as explicitly invoking the superclass constructor

    public ScheduleServlet() {
        super();
        // TODO Auto-generated constructor stub
    }

As soon as I commented out the super.doPost(request, response); from within doPost() statement it worked perfectly...

protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

        //super.doPost(request, response);
        // More code here...

}

Needless to say, I need to re-read on super() best practices :p

urllib is a standard library, you do not have to install it. Simply import urllib

dataGridView1.AutoSizeRowsMode = DataGridViewAutoSizeRowsMode.AllCells;
for (int i = 0; i < dataGridView1.Columns.Count; i++)
{
    dataGridView1.Columns[i].AutoSizeMode = DataGridViewAutoSizeColumnMode.AllCells;
    dataGridView1.Columns[i].AutoSizeMode = DataGridViewAutoSizeColumnMode.NotSet;
}

How about sapply (not really necessary for this simple case):

newData<- sapply(data, function(x) x^2)

sudo dscl . -create /Users/joeadmin
sudo dscl . -create /Users/joeadmin UserShell /bin/bash
sudo dscl . -create /Users/joeadmin RealName "Joe Admin" 
sudo dscl . -create /Users/joeadmin UniqueID "510"
sudo dscl . -create /Users/joeadmin PrimaryGroupID 20
sudo dscl . -create /Users/joeadmin NFSHomeDirectory /Users/joeadmin
sudo dscl . -passwd /Users/joeadmin password 
sudo dscl . -append /Groups/admin GroupMembership joeadmin

press enter after every sentence

Then do a:

sudo reboot

Change joeadmin to whatever you want, but it has to be the same all the way through. You can also put a password of your choice after password.

Swift 3:
Try this:

extension String {
    func htmlAttributedString() -> NSAttributedString? {
        guard let data = self.data(using: String.Encoding.utf16, allowLossyConversion: false) else { return nil }
        guard let html = try? NSMutableAttributedString(
            data: data,
            options: [NSDocumentTypeDocumentAttribute: NSHTMLTextDocumentType],
            documentAttributes: nil) else { return nil }
        return html
    }
}  

And for using:

let str = "<h1>Hello bro</h1><h2>Come On</h2><h3>Go sis</h3><ul><li>ME 1</li><li>ME 2</li></ul> <p>It is me bro , remember please</p>"

self.contentLabel.attributedText = str.htmlAttributedString()

If your view is set to hidden by default or you change the Hidden state which I think you should in many cases, then none of the approaches in this page will give you both FadeIn/FadeOut animation, it will only animate one of these states, the reason is you are setting the Hidden state to false before calling UIView.animate method which will cause a sudden visibility and if you only animate the alpha then the object space is still there but it's not visible which will result to some UI issues.

So the best approach is to check first if the view is hidden then set the alpha to 0.0, like this when you set the Hidden state to false you won't see a sudden visibility.

func hideViewWithFade(_ view: UIView) {
    if view.isHidden {
        view.alpha = 0.0
    }

    view.isHidden = false

    UIView.animate(withDuration: 0.3, delay: 0.0, options: .transitionCrossDissolve, animations: {
        view.alpha = view.alpha == 1.0 ? 0.0 : 1.0
    }, completion: { _ in
        view.isHidden = !Bool(truncating: view.alpha as NSNumber)
    })
}

The problem here was a typo error in the password used, which was not easily identified due to the characters / letters used in the password.

here is a test script to run on your server to see what is reliabel.

<?php
$host = gethostname();
$ip = gethostbyname($host);
echo "gethostname and gethostbyname: $host at $ip<br>";
$server = $_SERVER['SERVER_ADDR'];
echo "_SERVER[SERVER_ADDR]: $server<br>";
$my_current_ip=exec("ifconfig | grep -Eo 'inet (addr:)?([0-9]*\.){3}[0-9]*' | grep -Eo '([0-9]*\.){3}[0-9]*' | grep -v '127.0.0.1'");
echo "exec ifconfig ... : $my_current_ip<br>";
$external_ip = file_get_contents("http://ipecho.net/plain");
echo "get contents ipecho.net: $external_ip<br>";
?>

The only different option in there is using fiel_get_contents rather than curl for the extrernal website lookup.

This is the result of hitting the web page on a shared hosting, free account. (actual server name and IP changed)

gethostname and gethostbyname: freesites.servercluster.com at 345.27.413.51
_SERVER[SERVER_ADDR]: 127.0.0.7
exec ifconfig ... :
get contents ipecho.net: 345.27.413.51

Why needed this? Decided to point A record at server to see if it opens the web page. Later ran script to save ip and update on ghost site on same server to lookup IP and alert if changed.

In this case, good results optained by:

gethostname() & 
gethostbyname($host)
or 
file_get_contents("http://ipecho.net/plain")

Include the attribute Method="text" on the xsl:output tag and include newlines in your literal content in the XSL at the appropriate points. If you prefer to keep the source code of your XSL tidy use the entity 
 where you want a new line.

$(function () {
    $( ".droppable-area" ).sortable({
                connectWith: ".connected-sortable",
                containment: ".droppable-area", //(parent div)
                stack: '.connected-sortable div'
            }).disableSelection();
});

Take a look at the following function - REPLACE():

select replace(DataColumn, StringToReplace, NewStringValue)

//example to replace the s in test with the number 1
select replace('test', 's', '1')
//yields te1t

http://msdn.microsoft.com/en-us/library/ms186862.aspx

EDIT
If you want to remove a string, simple use the replace function with an empty string as the third parameter like:

select replace(DataColumn, 'StringToRemove', '')

Use max-width:100%;, height: auto; and display:block; as follow:

image {
    max-width:100%;
    height: auto;
    display:block;
}

The RareCpp library makes for fairly easy and intuitive reflection - all field/type information is designed to either be available in arrays or to feel like array access. It's written for C++17 and works with Visual Studios, g++, and Clang. The library is header only, meaning you need only copy "Reflect.h" into your project to use it.

Reflected structs or classes need the REFLECT macro, where you supply the name of the class you're reflecting and the names of the fields.

class FuelTank {
    public:
        float capacity;
        float currentLevel;
        float tickMarks[2];

    REFLECT(FuelTank, capacity, currentLevel, tickMarks)
};

That's all there is, no additional code is needed to setup reflection. Optionally you can supply superclasses (in the parenthesis of the first argument) and field annotations (in the parenthesis preceeding the field you want to annotate) to be able to traverse superclasses or add additional compile-time information to a field (such as Json::Ignore).

Looping through fields can be as simple as...

for ( size_t i=0; i<FuelTank::Class::TotalFields; i++ )
    std::cout << FuelTank::Class::Fields[i].name << std::endl;

You can loop through an object instance to access field values (which you can read or modify) and field type information...

FuelTank::Class::ForEachField(fuelTank, [&](auto & field, auto & value) {
    using Type = typename std::remove_reference<decltype(value)>::type;
    std::cout << TypeToStr<Type>() << " " << field.name << ": " << value << std::endl;
});

A JSON Library is built on top of RandomAccessReflection which auto identifies appropriate JSON output representations for reading or writing, and can recursively traverse any reflected fields, as well as arrays and STL containers.

struct MyOtherObject { int myOtherInt; REFLECT(MyOtherObject, myOtherInt) };
struct MyObject
{
    int myInt;
    std::string myString;
    MyOtherObject myOtherObject;
    std::vector<int> myIntCollection;

    REFLECT(MyObject, myInt, myString, myOtherObject, myIntCollection)
};

int main()
{
    MyObject myObject = {};
    std::cout << "Enter MyObject:" << std::endl;
    std::cin >> Json::in(myObject);
    std::cout << std::endl << std::endl << "You entered:" << std::endl;
    std::cout << Json::pretty(myObject);
}

The above could be ran like so...

Enter MyObject:
{
  "myInt": 1337, "myString": "stringy", "myIntCollection": [2,4,6],
  "myOtherObject": {
    "myOtherInt": 9001
  }
}


You entered:
{
  "myInt": 1337,
  "myString": "stringy",
  "myOtherObject": {
    "myOtherInt": 9001
  },
  "myIntCollection": [ 2, 4, 6 ]
}

This can be achieved with the onresize property of the GlobalEventHandlers interface in JavaScript, by assigning a function to the onresize property, like so:

window.onresize = functionRef;

The following code snippet demonstrates this, by console logging the innerWidth and innerHeight of the window whenever it's resized. (The resize event fires after the window has been resized)

function resize() {_x000D_
  console.log("height: ", window.innerHeight, "px");_x000D_
  console.log("width: ", window.innerWidth, "px");_x000D_
}_x000D_
_x000D_
window.onresize = resize;

<p>In order for this code snippet to work as intended, you will need to either shrink your browser window down to the size of this code snippet, or fullscreen this code snippet and resize from there.</p>

I like to use the CPAN 'r' command for this. You can get into the CPAN shell with the old style:

sudo perl -MCPAN -e shell

or, on most newer systems, there is a 'cpan' command, so this command will get you to the shell:

sudo cpan

(You typically have to use 'sudo' to run it as root, or use 'su -' to become root before you run it, unless you have cpan set up to let you run it as a normal user, but install as root. If you don't have root on this machine, you can still use the CPAN shell to find out this information, but you won't be able to install modules, and you may have to go through a bit of setup the first time you run it.)

Then, once you're in the cpan shell, you can use the 'r' command to report all installed modules and their versions. So, at the "cpan>" prompt, type 'r'. This will list all installed modules and their versions. Use '?' to get some more help.

First of all, Thanks to code author!

You just need to uri-encode your SVG html and replace the one in the image variable after "data:image/svg+xml" in the for loop.

For uri encoding you can use uri-encoder-decoder

You can decode the existing svg code first to get a better understanding of what is written.

If I got you correctly, it is as easy as

cartDiv.id = "someID";

No need for jQuery.

Have a look at the properties of a DOM Element.

For classes it is the same:

cartDiv.className = "classes here";

But note that this will overwrite already existing class names. If you want to add and remove classes dynamically, you either have to use jQuery or write your own function that does some string replacement.

Since 1.10 release, you can now add multiple tags at once on build:

docker build -t name1:tag1 -t name1:tag2 -t name2 .

Source: Add ability to add multiple tags with docker build

Background

Invariant's answer is a good resource for how everything was started and what was the state of JavaFX on embedded and mobile in beginning of 2014. But, a lot has changed since then and the users who stumble on this thread do not get the updated information.

Most of my points are related to Invariant's answer, so I would suggest to go through it first.

Current Status of JavaFX on Mobile / Embedded

UPDATE

JavaFXPorts has been deprecated. Gluon Mobile now uses GraalVM underneath. There are multiple advantages of using GraalVM. Please check this blogpost from Gluon. The IDE plugins have been updated to use Gluon Client plugins which leverages GraalVM to AOT compile applications for Android/iOS.

Old answer with JavaFXPorts

Some bad news first:

• RoboVM is dead
• Oracle killed JavaFX on Embedded Devices

Now, some good news:

• JavaFX still runs on Android, iOS and most of the Embedded devices
• JavaFXPorts SDK for android, iOS and embedded devices can be downloaded from here
• JavaFXPorts project is still thriving and it is easier than ever to run JavaFX on mobile devices, all thanks to the IDE plugins that is built on top of these SDKs and gets you started in a few minutes without the hassle of installing any SDK
• JavaFX 3D is now supported on mobile devices
• GluonVM to replace RoboVM enabling Java 9 support for mobile developers. Yes, you heard it right.
• Mobile Project has been launched by Oracle to support JDK on all major mobile platforms. It should support JavaFX as well ;)

How to get started

If you are not the DIY kind, I would suggest to install the IDE plugin on your favourite IDE and get started.

Most of the documentation on how to get started can be found here and some of the samples can be found here.

Use the below code for converting XML to JSON.

var json = new JavaScriptSerializer().Serialize(obj);

You must press enter after continuation character

Note: Space after continuation character leads to error

cost = {"apples": [3.5, 2.4, 2.3], "bananas": [1.2, 1.8]}

0.9 * average(cost["apples"]) + \ """enter here"""
0.1 * average(cost["bananas"])

much easier use it

<input type="button" id="loadFileXml" value="Custom Button Name"onclick="document.getElementById('file').click();" />
<input type="file" style="display:none;" id="file" name="file"/>

Try to convert Prize into decimal format...

import java.math.BigDecimal;
import java.math.RoundingMode;

public class Bigdecimal {
    public static boolean isEmpty (String st) {
        return st == null || st.length() < 1; 
    }
    public static BigDecimal bigDecimalFormat(String Preis){        
        //MathContext   mi = new MathContext(2);
        BigDecimal bd = new BigDecimal(0.00);

                         bd = new BigDecimal(Preis);


            return bd.setScale(2, RoundingMode.HALF_UP);

        }
    public static void main(String[] args) {
        String cost = "12.12";
        if (!isEmpty(cost) ){
            try {
               BigDecimal intCost = bigDecimalFormat(cost);
               System.out.println(intCost);
               List<Book> books = bookService.findBooksCheaperThan(intCost);  
            } catch (NumberFormatException e) {
               System.out.println("This is not a number");
               System.out.println(e.getMessage());
            }
        }

}
}

This is possible due to type erasure. You will find that

List<TestA> x = new ArrayList<TestA>();
List<TestB> y = new ArrayList<TestB>();
x.getClass().equals(y.getClass()); // true

Internally both lists are of type List<Object>. For that reason you can't cast one to the other - there is nothing to cast.

Angular Concepts

• imports makes the exported declarations of other modules available in the current module
• declarations are to make directives (including components and pipes) from the current module available to other directives in the current module. Selectors of directives, components or pipes are only matched against the HTML if they are declared or imported.
• providers are to make services and values known to DI (dependency injection). They are added to the root scope and they are injected to other services or directives that have them as dependency.

A special case for providers are lazy loaded modules that get their own child injector. providers of a lazy loaded module are only provided to this lazy loaded module by default (not the whole application as it is with other modules).

For more details about modules see also https://angular.io/docs/ts/latest/guide/ngmodule.html

• exports makes the components, directives, and pipes available in modules that add this module to imports. exports can also be used to re-export modules such as CommonModule and FormsModule, which is often done in shared modules.

• entryComponents registers components for offline compilation so that they can be used with ViewContainerRef.createComponent(). Components used in router configurations are added implicitly.

TypeScript (ES2015) imports

import ... from 'foo/bar' (which may resolve to an index.ts) are for TypeScript imports. You need these whenever you use an identifier in a typescript file that is declared in another typescript file.

Angular's @NgModule() imports and TypeScript import are entirely different concepts.

See also jDriven - TypeScript and ES6 import syntax

Most of them are actually plain ECMAScript 2015 (ES6) module syntax that TypeScript uses as well.

The approach you should take is to install pip for Python 3.2.

You do this in the following way:

$ curl -O https://bootstrap.pypa.io/get-pip.py
$ sudo python3.2 get-pip.py

Then, you can install things for Python 3.2 with pip-3.2, and install things for Python 2-7 with pip-2.7. The pip command will end up pointing to one of these, but I'm not sure which, so you will have to check.

I believe to check if a key exists in a hash you just do

if (exists $strings{$string}) {
    ...
} else {
    ...
}

I ended up with this function to safely replace text without side effects (so far):

function replaceInText(element, pattern, replacement) {
    for (let node of element.childNodes) {
        switch (node.nodeType) {
            case Node.ELEMENT_NODE:
                replaceInText(node, pattern, replacement);
                break;
            case Node.TEXT_NODE:
                node.textContent = node.textContent.replace(pattern, replacement);
                break;
            case Node.DOCUMENT_NODE:
                replaceInText(node, pattern, replacement);
        }
    }
}

It's for cases where the 16kB of findAndReplaceDOMText are a bit too heavy.

I had similar error: "Expecting value: line 1 column 1 (char 0)"

It helped for me to add "myfile.seek(0)", move the pointer to the 0 character

with open(storage_path, 'r') as myfile:
if len(myfile.readlines()) != 0:
    myfile.seek(0)
    Bank_0 = json.load(myfile)

This script that will output the files with the directory structure under "fixedFiles".

I had the same problem when trying to make a connection on OBIEE to Oracle db. I changed my Windows timezone from (GMT+01:00) West Central Africa to (GMT+01:00) Brussels, Copenhagen, Madrid, Paris. Then I rebooted my computer and it worked just fine. Seems like Oracle was not able to recognize the west central Africa timezone.

Simply Use

 FragmentManager fm = getActivity().getSupportFragmentManager();

Remember always when accessing fragment inflating in MainLayout use Casting or getActivity().

The faster way for your case is:

    jTable.repaint(); // Repaint all the component (all Cells).

The optimized way when one or few cell change:

    ((AbstractTableModel) jTable.getModel()).fireTableCellUpdated(x, 0); // Repaint one cell.

No, this seems perfectly reasonable. There is a List<T>.AddRange() method that basically does just this, but requires your collection to be a concrete List<T>.

Depending on how complicated your regular expression is, you could possibly just use simple string slicing. I'm not sure about the practicality of this for your application or whether or not it would actually offer any speed improvements.

'testsentence'['stsen']
=> 'stsen' # evaluates to true
'testsentence'['koala']
=> nil # evaluates to false

Try update your SDK Tools items, and then delete all currently created emulator and recreate again. it works for me

I know its old topic, but I'd like to contribute too.

With the newer version of boto3 and python, you can get the files as follow:

import os
import boto3
from botocore.exceptions import ClientError    

client = boto3.client('s3')

bucket = client.list_objects(Bucket=BUCKET_NAME)
for content in bucket["Contents"]:
    key = content["key"]

Keep in mind that this solution not comprehends pagination.

For more information: https://boto3.amazonaws.com/v1/documentation/api/latest/reference/services/s3.html#S3.Client.list_objects

You can also use a function in order to substitute different kind of regular expression or other pattern with the use of a list. With that, you can mixed regular expression, character class, and really basic text pattern. It's really useful when you need to substitute a lot of elements like HTML ones.

*NB: works with Python 3.x

import re  # Regular expression library


def string_cleanup(x, notwanted):
    for item in notwanted:
        x = re.sub(item, '', x)
    return x

line = "<title>My example: <strong>A text %very% $clean!!</strong></title>"
print("Uncleaned: ", line)

# Get rid of html elements
html_elements = ["<title>", "</title>", "<strong>", "</strong>"]
line = string_cleanup(line, html_elements)
print("1st clean: ", line)

# Get rid of special characters
special_chars = ["[!@#$]", "%"]
line = string_cleanup(line, special_chars)
print("2nd clean: ", line)

In the function string_cleanup, it takes your string x and your list notwanted as arguments. For each item in that list of elements or pattern, if a substitute is needed it will be done.

The output:

Uncleaned:  <title>My example: <strong>A text %very% $clean!!</strong></title>
1st clean:  My example: A text %very% $clean!!
2nd clean:  My example: A text very clean

To install Openjdk 11 in Ubuntu, the following commands worked well.

sudo add-apt-repository ppa:openjdk-r/ppa
sudo apt-get update
sudo apt install openjdk-11-jdk

It should work - as long as the data variable is actually an array containing a dictionary with the key SPORT

NSArray *data = [NSArray arrayWithObject:[NSMutableDictionary dictionaryWithObject:@"foo" forKey:@"BAR"]];    
NSArray *filtered = [data filteredArrayUsingPredicate:[NSPredicate predicateWithFormat:@"(BAR == %@)", @"foo"]];

Filtered in this case contains the dictionary.

(the %@ does not have to be quoted, this is done when NSPredicate creates the object.)

The answer by @hybrid is quite informative, except it doesn't explain the purpose as mentioned by @ashitaka "What if you use the Mobile First approach? So, we have the mobile CSS first and then use min-width to target larger sites. We shouldn't use the only keyword in that context, right? "

Want to add in here that the purpose is simply to prevent non supporting browsers to use that Other device style as if it starts from "screen" without it will take it for a screen whereas if it starts from "only" style will be ignored.

Answering to ashitaka consider this example

<link rel="stylesheet" type="text/css" 
  href="android.css" media="only screen and (max-width: 480px)" />
<link rel="stylesheet" type="text/css" 
  href="desktop.css" media="screen and (min-width: 481px)" />

If we don't use "only" it will still work as desktop-style will also be used striking android styles but with unnecessary overhead. In this case, IF a browser is non-supporting it will fallback to the second Style-sheet ignoring the first.

A little test that shows how to parse a date in ISO8601 and that LocalDateTime does not handle DSTs.

 @Test
    public void shouldHandleDaylightSavingTimes() throws ParseException {

        //ISO8601 UTC date format
        SimpleDateFormat utcFormat = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSSXXX");

        // 1 hour of difference between 2 dates in UTC happening at the Daylight Saving Time
        Date d1 = utcFormat.parse("2019-10-27T00:30:00.000Z");
        Date d2 = utcFormat.parse("2019-10-27T01:30:00.000Z");

        //Date 2 is before date 2
        Assert.assertTrue(d1.getTime() < d2.getTime());
        // And there is 1 hour difference between the 2 dates
        Assert.assertEquals(1000*60*60, d2.getTime() - d1.getTime());

        //Print the dates in local time
        SimpleDateFormat localFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm z Z", Locale.forLanguageTag("fr_CH"));
        localFormat.setTimeZone(TimeZone.getTimeZone("Europe/Zurich"));

        //Both dates are at 02h30 local time (because of DST), but one is CEST +0200 and the other CET +0100 (clock goes backwards)
        Assert.assertEquals("2019-10-27 02:30 CEST +0200", localFormat.format(d1));
        Assert.assertEquals("2019-10-27 02:30 CET +0100", localFormat.format(d2));

        //Small test that shows that LocalDateTime does not handle DST (and should not be used for storing timeseries data)
        LocalDateTime ld1 = LocalDateTime.ofInstant(d1.toInstant(), ZoneId.of("Europe/Zurich"));
        LocalDateTime ld2 = LocalDateTime.ofInstant(d2.toInstant(), ZoneId.of("Europe/Zurich"));

        //Note that a localdatetime does not handle DST, therefore the 2 dates are the same
        Assert.assertEquals(ld1, ld2);

        //They both have the following local values
        Assert.assertEquals(2019, ld1.getYear());
        Assert.assertEquals(27, ld1.getDayOfMonth());
        Assert.assertEquals(10, ld1.getMonthValue());
        Assert.assertEquals(2, ld1.getHour());
        Assert.assertEquals(30, ld1.getMinute());
        Assert.assertEquals(0, ld1.getSecond());

    }

Well, quick answer would to take a look at the 'scp' manpage, or perhaps rsync - depending exactly on what you need to copy. If you had to, you could even do tar-over-ssh:

tar cvf - | ssh server tar xf -

The datetime.now() is evaluated when the class is created, not when new record is being added to the database.

To achieve what you want define this field as:

date = models.DateTimeField(auto_now_add=True)

This way the date field will be set to current date for each new record.

if you can't or don't want to set the autoincrement property of the id, you can set value for the id for each row, like this:

INSERT INTO role (id, name, created)
SELECT 
      (select max(id) from role) + ROW_NUMBER() OVER (ORDER BY name)
    , name
    , created
FROM (
    VALUES 
      ('Content Coordinator', GETDATE())
    , ('Content Viewer', GETDATE())
) AS x(name, created)

To deserialize the response need to use HashMap:

String resp = ...//String output from your source

Gson gson = new GsonBuilder().create();
gson.fromJson(resp,TheResponse.class);

class TheResponse{
 HashMap<String,Song> songs;
}

class Song{
  String id;
  String pos;
}

The problem occurs in declaring context, while using Glide for ImageView or While using intent in recyclerview for item onClick. I Found this working for me which helps me to Declare context to use in Glide or Intent or Toast.

public class NoteAdapter extends FirestoreRecyclerAdapter<Note,NoteAdapter.NoteHolder> {

Context context;

public NoteAdapter(@NonNull FirestoreRecyclerOptions<Note> options) {
    super(options);
}

@Override
protected void onBindViewHolder(@NonNull NoteHolder holder, int position, @NonNull Note model) {
    holder.r_tv.setText(model.getTitle());
    Glide.with(CategoryActivity.context).load(model.getImage()).into(holder.r_iv);

    context = holder.itemView.getContext();

    holder.itemView.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Intent i = new Intent(context, SuggestActivity.class);
            context.startActivity(i);
        }
    });

}

@NonNull
@Override
public NoteHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {

    View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.row_category,parent,false);

    return new NoteHolder(v);
}

public static class NoteHolder extends RecyclerView.ViewHolder
{
    TextView r_tv;
    ImageView r_iv;

    public NoteHolder(@NonNull View itemView) {
        super(itemView);

        r_tv = itemView.findViewById(R.id.r_tv);
        r_iv = itemView.findViewById(R.id.r_iv);


    }
}
}

in VB 2008 (VB 9.0) and later, prefix Right() as Microsoft.VisualBasic.Right(string, number of characters)

Dim str as String = "Hello World"

Msgbox(Microsoft.VisualBasic.Right(str,5))

'World"

Same goes for Left() too.

I hope ls -lah will do the job. Also if you are new to unix environment please go to http://www.tutorialspoint.com/unix/unix-useful-commands.htm

just try this , finally this works for me :

//delete backslashes ( \ ) :
            data = data.replaceAll("[\\\\]{1}[\"]{1}","\"");
//delete first and last double quotation ( " ) :
            data = data.substring(data.indexOf("{"),data.lastIndexOf("}")+1);
            JSONObject json = new JSONObject(data);

@Jonathan Sampson i think your solution is wrong if you use multiple @media.

You should use (min-width first):

@media screen and (min-width:400px) and (max-width:900px){
   ...
}

Use the operator sizeof, it will give you the size of a type expressed in byte. One byte is eight bits. See the following program:

#include <iostream>

int main(int,char**)
{
 std::cout << "unsigned long long " << sizeof(unsigned long long) << "\n";
 std::cout << "unsigned long long int " << sizeof(unsigned long long int) << "\n";
 return 0;
}

This may be helpful

def digits_to_number(digits):
    return reduce(lambda x,y : x+y, map(str,digits))

print digits_to_number([1,2,3,4,5])

$().jquery will give you its version as a string.

The accepted answer is correct, BUT it will mean that phone numbers, maps, email addresses, and regular links e.g. http://google.com without href tags will NO LONGER be clickable since you can't have autolink in the xml.

The only complete solution to have EVERYTHING clickable that I have found is the following:

Spanned text = Html.fromHtml(myString);
URLSpan[] currentSpans = text.getSpans(0, text.length(), URLSpan.class);
SpannableString buffer = new SpannableString(text);
Linkify.addLinks(buffer, Linkify.ALL);
for (URLSpan span : currentSpans) {
    int end = text.getSpanEnd(span);
    int start = text.getSpanStart(span);
    buffer.setSpan(span, start, end, 0);
}
textView.setText(buffer);
textView.setMovementMethod(LinkMovementMethod.getInstance());

And the TextView should NOT have android:autolink. There's no need for android:linksClickable="true" either; it's true by default.

This looks like a good reference although it's not in Regex.

Really, unless you're actually shipping something to your users, I don't think it's worth the effort. And if you are shipping it, there are address cleaning tools/services you can look into to make it way easier on yourself.

You can check if it can be converted to decimal. If yes, then its a number

from decimal import Decimal

def is_number(value):
    try:
        value = Decimal(value)
        return True
    except:
        return False

print is_number(None)   // False
print is_number(0)      // True
print is_number(2.3)    // True
print is_number('2.3')  // True (caveat!)

I got this same error working in Eclipse with Maven with the additional information

schema_reference.4: Failed to read schema document 'https://maven.apache.org/xsd/maven-4.0.0.xsd', because 1) could not find the document; 2) the document could not be read; 3) the root element of the document is not <xsd:schema>.

This was after copying in a new controller and it's interface from a Thymeleaf example. Honestly, no matter how careful I am I still am at a loss to understand how one is expected to figure this out. On a (lucky) guess I right clicked the project, clicked Maven and Update Project which cleared up the issue.

Use execfile for Python 2:

>>> execfile('C:\\test.py')

Use exec for Python 3

>>> exec(open("C:\\test.py").read())

If you are using RichTextBox control. You can simply define the ToolTip object and show the tool-tip as the text is selected by moving the mouse inside the RichTextBox control.

    ToolTip m_ttInput = new ToolTip(); // define as member variable

    private void rtbInput_SelectionChanged(object sender, EventArgs e)
    {
        if (rtbInput.SelectedText.Length > 0) 
        {
            m_ttInput.Show(rtbInput.SelectedText.Length.ToString(), rtbInput, 1000);
        }
    }

You may consider using CRON for that kind of operation. Sending mass mail at once is certainly not good, it may be detected as spam, ddos, crash your server etc.

So CRON could be a great solution, send 100 mails at once, then wait a few minutes, next 100, etc.

There is a major error in the tutorials destined for newbies here: http://developer.android.com/training/basics/actionbar/styling.html

It is major because it is almost impossible to detect cause of error for a newbie.

The error is that this tutorial explicitly states that the tutorial is valid for api level 11 (Android 3.0), while in reality this is only true for the theme Theme.Holo (without further extensions and variants)

But this tutorial uses the the theme Theme.holo.Light.DarkActionBar which is only a valid theme from api level 14 (Android 4.0) and above.

This is only one of many examples on errors found in these tutorials (which are great in other regards). Somebody should correct these errors this weekend because they are really costly and annoying timethieves. If there is a way I can send this info to the Android team, then please tell me and I will do it. Hopefully, however, they read Stackoverflow. (let me suggest: The Android team should consider to put someone newbie to try out all tutorials as a qualification that they are valid).

Another error I (and countless other people) have found is that the appcombat backward compliance module really is not working if you strictly follow the tutorials. Error unknown. I had to give up.

Regarding the error in this thread, here is a quote from the tutorial text with italics on the mismatch:

" For Android 3.0 and higher only

When supporting Android 3.0 and higher only, you can define the action bar's background like this:

    <resources>
        <!-- the theme applied to the application or activity -->
        <style name="CustomActionBarTheme"
        parent="@style/Theme.Holo.Light.DarkActionBar"> 

ERROR1: Only Theme.Holo can be used with Android 3.0. Therefore, remove the "Light.DarkActionBar etc.

ERROR2: @style/Theme.Holo"> will not work. It is necessary to write @android:style/Theme.Holo">in order to indicate that it is a built in Theme that is being referenced. (A bit strange that "built in" is not the default, but needs to be stated?)

The compiler advice for error correction is to define api level 14 as minimum sdk. This is not optimal because it creates incompliance to Andreoid 3.0 (api level 11). Therefore, I use Theme.Holo only and this seems to work fine (a fresh finding, though).

I am using Netbeans with Android support. Works nicely.

Whole chapter 4 talks about conversions, but I think you should be mostly interested in these :

4.5 Integral promotions [conv.prom]
An rvalue of type char, signed char, unsigned char, short int, or unsigned short int can be converted to an rvalue of type int if int can represent all the values of the source type; other-
wise, the source rvalue can be converted to an rvalue of type unsigned int.
An rvalue of type wchar_t (3.9.1) or an enumeration type (7.2) can be converted to an rvalue of the first
of the following types that can represent all the values of its underlying type: int, unsigned int,
long, or unsigned long.
An rvalue for an integral bit-field (9.6) can be converted to an rvalue of type int if int can represent all
the values of the bit-field; otherwise, it can be converted to unsigned int if unsigned int can rep-
resent all the values of the bit-field. If the bit-field is larger yet, no integral promotion applies to it. If the
bit-field has an enumerated type, it is treated as any other value of that type for promotion purposes.
An rvalue of type bool can be converted to an rvalue of type int, with false becoming zero and true
becoming one.
These conversions are called integral promotions.

4.6 Floating point promotion [conv.fpprom]
An rvalue of type float can be converted to an rvalue of type double. The value is unchanged.
This conversion is called floating point promotion.

Therefore, all conversions involving float - the result is float.

Only the one involving both int - the result is int : int / int = int

I had the same issue, and the following syntax worked for me:

df.filter(df("state")==="TX").show()

I'm using Spark 1.6.

Ok, finally found the solution.

Probably due to lack of experience with ReactJS and web development...

    var Task = React.createClass({
    render: function() {
      var percentage = this.props.children + '%';
      ....
        <div className="ui-progressbar-value ui-widget-header ui-corner-left" style={{width : percentage}}/>
      ...

I created the percentage variable outside in the render function.

Where x is the collection:

Foo[] foos = x.toArray(new Foo[x.size()]);

You need to detect the click from js side, your HTML remaining same. Note: this method is deprecated since v3.5.5 and removed in v4.

$("button").click(function() {
    var $btn = $(this);
    $btn.button('loading');
    // simulating a timeout
    setTimeout(function () {
        $btn.button('reset');
    }, 1000);
});

Also, don't forget to load jQuery and Bootstrap js (based on jQuery) file in your page.

JSFIDDLE

Official Documentation

Add this for pages not currently on your site...

ErrorDocument 404 http://example.com/

Along with your Redirect 301 / http://www.thenewdomain.com/ that should cover all the bases...

Good luck!

You convert type np.dot(X, T) to float32 like this:

z=np.array(np.dot(X, T),dtype=np.float32)

def sigmoid(X, T):
    return (1.0 / (1.0 + np.exp(-z)))

Hopefully it will finally work!

"Timeline (responsive)" snippet:

This looks very, very close to what your example shows. The bootstrap snippet linked below covers all the bases you are looking for. I've been considering it myself, with the same requirements you have ( especially responsiveness ). This morphs well between screen sizes and devices.

You can fork this and use it as a great starting point for your specific expectations:

Simplest way is to save it to temp file and then read it:

import pandas as pd

CSV_FILE_NAME = 'temp_file.csv'  # Consider creating temp file, look URL below
with open(CSV_FILE_NAME, 'w') as outfile:
    outfile.write(TESTDATA)
df = pd.read_csv(CSV_FILE_NAME, sep=';')

Right way of creating temp file: How can I create a tmp file in Python?

Another way ( longer ) In VB.net [ Say 2300 Start and 0700 Finish next day ]

If tsStart > tsFinish Then

                            ' Take Hours difference and adjust accordingly
                            tsDifference = New TimeSpan((24 - tsStart.Hours) + tsFinish.Hours, 0, 0)

                            ' Add Minutes to Difference
                            tsDifference = tsDifference.Add(New TimeSpan(0, Math.Abs(tsStart.Minutes - tsFinish.Minutes), 0))


                            ' Add Seonds to Difference
                            tsDifference = tsDifference.Add(New TimeSpan(0, 0, Math.Abs(tsStart.Seconds - tsFinish.Seconds)))

Presumably you're passing the arguments in on the command line as follows:

php /path/to/wwwpublic/path/to/script.php arg1 arg2

... and then accessing them in the script thusly:

<?php
// $argv[0] is '/path/to/wwwpublic/path/to/script.php'
$argument1 = $argv[1];
$argument2 = $argv[2];
?>

What you need to be doing when passing arguments through HTTP (accessing the script over the web) is using the query string and access them through the $_GET superglobal:

Go to http://yourdomain.com/path/to/script.php?argument1=arg1&argument2=arg2

... and access:

<?php
$argument1 = $_GET['argument1'];
$argument2 = $_GET['argument2'];
?>

If you want the script to run regardless of where you call it from (command line or from the browser) you'll want something like the following:

EDIT: as pointed out by Cthulhu in the comments, the most direct way to test which environment you're executing in is to use the PHP_SAPI constant. I've updated the code accordingly:

<?php
if (PHP_SAPI === 'cli') {
    $argument1 = $argv[1];
    $argument2 = $argv[2];
}
else {
    $argument1 = $_GET['argument1'];
    $argument2 = $_GET['argument2'];
}
?>

As jean-baptiste-yunès said, if your stream is based on a java List then using an AtomicInteger and its incrementAndGet method is a very good solution to the problem and the returned integer does correspond to the index in the original List as long as you do not use a parallel stream.

Need to see whether you got ant folder moved by mistake or unknowingly. It is set in environment variables.I resolved this once as mentioned below.

I removed ant folder by mistake and placed in another folder.I went to command prompt and typed "path". It has given me path as "F:\apache-ant-1.9.4\". So I moved the ant back to F drive and it resolved the issue.

No behaviors can be set by CSS. The only way to disable something in CSS is to make it invisible by either setting display:none or simply putting div with transparent img all over it and changing their z-orders to disable user focusing on it with mouse. Even though, user will still be able to focus with tab from another field.

Installing Visual C++ is a good first step, though I couldn't say for sure whether the 2010 version will work. Anyway give it a try.

Look for vcvarsall.bat in the Visual C++ installation directory (for Visual Studio 2010 it's in ProgramFiles\Microsoft Visual Studio 10.0\VC). Then add that directory to the system path. If you're doing this on the command line, you can try:

path %path%;c:\path\to\vs2010\bin

then try again to run whatever you were trying to run.

For more permanent effect, add it in the computer system path settings.

There is only one character wrong in the code you tried:

Charset characterSet = Charset.forName("US-ASCII");
String string = "Wazzup";
byte[] bytes = String.getBytes(characterSet);
               ^

Notice the upper case "String". This tries to invoke a static method on the string class, which does not exist. Instead you need to invoke the method on your string instance:

byte[] bytes = string.getBytes(characterSet);

In the GSM specification 3GPP TS 11.11, there are 10 bytes set aside in the MSISDN EF (6F40) for 'dialing number'. Since this is the GSM representation of a phone number, and it's usage is nibble swapped, (and there is always the possibility of parentheses) 22 characters of data should be plenty.

In my experience, there is only one instance of open/close parentheses, that is my reasoning for the above.

Please use dataset

var article = document.querySelector('#electriccars'),
    data = article.dataset;

// data.columns -> "3"
// data.indexnumber -> "12314"
// data.parent -> "cars"

so in your case for setting data:

getElementById('item1').dataset.icon = "base2.gif";

It's certainly possible to grab a screenshot using the .NET Framework. The simplest way is to create a new Bitmap object and draw into that using the Graphics.CopyFromScreen method.

Sample code:

using (Bitmap bmpScreenCapture = new Bitmap(Screen.PrimaryScreen.Bounds.Width, 
                                            Screen.PrimaryScreen.Bounds.Height))
using (Graphics g = Graphics.FromImage(bmpScreenCapture))
{
    g.CopyFromScreen(Screen.PrimaryScreen.Bounds.X,
                     Screen.PrimaryScreen.Bounds.Y,
                     0, 0,
                     bmpScreenCapture.Size,
                     CopyPixelOperation.SourceCopy);
}

Caveat: This method doesn't work properly for layered windows. Hans Passant's answer here explains the more complicated method required to get those in your screen shots.

Depending on what you plan to do with your sentence-as-a-list, you may want to look at the Natural Language Took Kit. It deals heavily with text processing and evaluation. You can also use it to solve your problem:

import nltk
words = nltk.word_tokenize(raw_sentence)

This has the added benefit of splitting out punctuation.

Example:

>>> import nltk
>>> s = "The fox's foot grazed the sleeping dog, waking it."
>>> words = nltk.word_tokenize(s)
>>> words
['The', 'fox', "'s", 'foot', 'grazed', 'the', 'sleeping', 'dog', ',', 
'waking', 'it', '.']

This allows you to filter out any punctuation you don't want and use only words.

Please note that the other solutions using string.split() are better if you don't plan on doing any complex manipulation of the sentence.

[Edited]

You could define a mapping of air pressure to servo angle, for example:

def calc_angle(pressure, min_p=1000, max_p=1200):     return 360 * ((pressure - min_p) / float(max_p - min_p))  angle = calc_angle(pressure) 

This will linearly convert pressure values between min_p and max_p to angles between 0 and 360 (you could include min_a and max_a to constrain the angle, too).

To pick a data structure, I wouldn't use a list but you could look up values in a dictionary:

d = {1000:0, 1001: 1.8, ...}  angle = d[pressure] 

but this would be rather time-consuming to type out!

The one that is mark as the solution is the better solution I been found until today, but has a serious problem with 0 (for example, 0.toFixedDown(2) gives -0.01). So I suggest to use this:

Number.prototype.toFixedDown = function(digits) {
  if(this == 0) {
    return 0;
  }
  var n = this - Math.pow(10, -digits)/2;
  n += n / Math.pow(2, 53); // added 1360765523: 17.56.toFixedDown(2) === "17.56"
  return n.toFixed(digits);
}

It looks like you indented so_far = new too much. Try this:

if guess in word:
    print("\nYes!", guess, "is in the word!")

    # Create a new variable (so_far) to contain the guess
    new = ""
    i = 0
    for i in range(len(word)):
        if guess == word[i]:
            new += guess
        else:
            new += so_far[i]
    so_far = new # unindented this

Inverse of a matrix using python and numpy:

>>> import numpy as np
>>> b = np.array([[2,3],[4,5]])
>>> np.linalg.inv(b)
array([[-2.5,  1.5],
       [ 2. , -1. ]])

Not all matrices can be inverted. For example singular matrices are not Invertable:

>>> import numpy as np
>>> b = np.array([[2,3],[4,6]])
>>> np.linalg.inv(b)

LinAlgError: Singular matrix

Solution to singular matrix problem:

try-catch the Singular Matrix exception and keep going until you find a transform that meets your prior criteria AND is also invertable.

Intuition for why matrix inversion can't always be done; like in singular matrices:

Imagine an old overhead film projector that shines a bright light through film onto a white wall. The pixels in the film are projected to the pixels on the wall.

If I stop the film projection on a single frame, you will see the pixels of the film on the wall and I ask you to regenerate the film based on what you see. That's easy, you say, just take the inverse of the matrix that performed the projection. An Inverse of a matrix is the reversal of the projection.

Now imagine if the projector was corrupted, and I put a distorted lens in front of the film. Now multiple pixels are projected to the same spot on the wall. I asked you again to "undo this operation with the matrix inverse". You say: "I can't because you destroyed information with the lens distortion, I can't get back to where we were, because the matrix is either Singular or Degenerate."

A matrix that can be used to transform some data into other data is invertable only if the process can be reversed with no loss of information. If your matrix can't be inverted, perhaps you are defining your projection using a guess-and-check methodology rather than using a process that guarantees a non-corrupting transform.

If you're using a heuristic or anything less than perfect mathematical precision, then you'll have to define another process to manage and quarantine distortions so that programming by Brownian motion can resume.

The Safari built in dev tool is great. I have to admit that Firebug on Firefox is my long time favorite, but I think that the Safari tool do a great job too!

Since in your question you said it's a PHP script, maybe the best solution could be to simply add in your script:

ignore_user_abort(TRUE);

In this way even if wget terminates, the PHP script goes on being processed at least until it does not exceeds max_execution_time limit (ini directive: 30 seconds by default).

As per wget anyay you should not change its timeout, according to the UNIX manual the default wget timeout is 900 seconds (15 minutes), whis is much larger that the 5-6 minutes you need.

Note that Mongo essentially stores JSON. If your app is dealing with a lot of JS Objects (with nesting) and you want to persist these objects then there is a very strong argument for using Mongo. It makes your DAL and MVC layers ultra thin, because they are not un-packaging all the JS object properties and trying to force-fit them into a structure (schema) that they don't naturally fit into.

We have a system that has several complex JS Objects at its heart, and we love Mongo because we can persist everything really, really easily. Our objects are also rather amorphous and unstructured, and Mongo soaks up that complication without blinking. We have a custom reporting layer that deciphers the amorphous data for human consumption, and that wasn't that difficult to develop.

As RocketDonkey suggested, your module itself needs to have some docstrings.

For example, in myModule/__init__.py:

"""
The mod module
"""

You'd also want to generate documentation for each file in myModule/*.py using

pydoc myModule.thefilename

to make sure the generated files match the ones that are referenced from the main module documentation file.

-Xmx sets the Maximum Heap size

Actually, the is operator checks for identity and == operator checks for equality.

From the language reference:

Types affect almost all aspects of object behavior. Even the importance of object identity is affected in some sense: for immutable types, operations that compute new values may actually return a reference to any existing object with the same type and value, while for mutable objects this is not allowed. E.g., after a = 1; b = 1, a and b may or may not refer to the same object with the value one, depending on the implementation, but after c = []; d = [], c and d are guaranteed to refer to two different, unique, newly created empty lists. (Note that c = d = [] assigns the same object to both c and d.)

So from the above statement we can infer that the strings, which are immutable types, may fail when checked with "is" and may succeed when checked with "is".

The same applies for int and tuple which are also immutable types.

As this question is still open, I might as well weigh in.

The good news is that over the past 5 or so years the Open Source tools have really matured and taken off in the space, the bad news is there are so many of them out there.

Here are my thoughts:-

Jmeter vs Grinder

Jmeter is driven from an XML style specification, that is constructed via a GUI.

Grinder uses Jython scripting within a muti-threaded Java framework, so more oriented to programmers.

Both tools will handle HTTP and HTTPS and have a proxy recorder to get you started. Both tools use the Controller model to drive multiple test agents so scalability is not an issue (given access to the Cloud).

Which is better:-

A hard call as the learning curve is steep with both tools as you get into the more complicated scripting requirements for url rewriting, correlation, providing unique data per Virtual User and simulating first time or returning Users (by manipulating the HTTP Headers).

That said I would start with Jmeter as this tool has a huge following and there are many examples and tutorials on the web for using this tool. If and when you come to a 'road block', that is something you can't 'easily' do with Jmeter then have a look at the Grinder. The good news is both these tools have the same Java requirement and a 'mix and match' solution is not out of the question.

Something new to add – Headless browsers running multiple instances of Selenium WebDriver.

This is a relatively new approach because it relies on the availability of resources that can now be provisioned from the Cloud. With this approach a Selenium (WebDriver) script is taken and run within a headless browser (i.e. WebDriver = New HtmlUnitDriver()) driver in multiple threads.

From experience around 25 instances of 'headless browsers' can be executed from the Amazon M1 Small Instance.

What this means is that all of the correlation, url rewriting issues disappear as you repurpose your functional testing scripts to become performance testing scripts.

The scalability is compromised as more VMs will be needed to drive the load, as compared with a HTTP driver such as the Grinder or Jmeter. That said, if you are looking to drive 500 Virtual Users then with 20 Amazon Small Instances (6 cents an hour each) at a cost of just $1.20 per hour gives you load that is very close to the Real User Experience.
