I think You are trying to use the normal URL of video Like this :

Copying Direct URL from YouTube

That doesn't let you display the content on other domains.To Tackle this up , You should use the Copy Embed Code feature provided by the YouTube itself .Like this :

Copy Embed Code ( YouTube )

That would free you up from any issues .

For the above Scenario :

• Go to Youtube Video

• Copy Embed Code

• Paste that into your Code ( Make sure you Escape all the " ( Inverted Commas) by \" .

I think a solution is to put count in back ticks

.filter("`count` >= 2")

I have the same problem, but I resolved adding jquery.min.js before angular.min.js.

By default Chrome extensions do not run in Incognito mode. You have to explicitly enable the extension to run in Incognito.

My version of @sampopes answer

function exportToExcel(that, id, hasHeader, removeLinks, removeImages, removeInputParams) {
if (that == null || typeof that === 'undefined') {
    console.log('Sender is required');
    return false;

if (!(that instanceof HTMLAnchorElement)) {
    console.log('Sender must be an anchor element');
    return false;
}

Requires an iframe

<iframe id="myIframe" style="opacity: 0; width: 100%; height: 0px;" seamless="seamless"></iframe>

Usage

$("#btnExportToExcel").click(function () {
    exportToExcel(this, '#mytable');
});

This has helped me in troubleshooting my problem. I had a similar symptoms in that maven would fail however running junit tests runs fine.

As it turns out my parent pom.xml contains the following definition:

    <plugin>
      <artifactId>maven-surefire-plugin</artifactId>
      <version>2.9</version>
      <configuration>
        <forkMode>pertest</forkMode>
        <argLine>-Xverify:none</argLine>
      </configuration>
    </plugin>

And in my project I override it to remove the argLine:

    <plugin>
       <artifactId>maven-surefire-plugin</artifactId>
       <configuration>
            <forkMode>pertest</forkMode>
            <argLine combine.self="override"></argLine>
          </configuration>
    </plugin>

Hopefully this will help someone in troubleshooting surefire plugin.

I know this post has been (very well) answered by Aquarelle but just in case somebody is having this issue with other tag forms with no text such as inputs i'll leave this here:

If you have an input in your form and placeholder is not showing because a white space at the beginning, this may be caused for you "value" attribute. In case you are using variables to fill the value of an input check that there are no white spaces between the commas and the variables.

example using twig for php framework symfony :

<input type="text" name="subject" value="{{ subject }}" placeholder="hello" />       <-- this is ok
<input type="text" name="subject" value" {{ subject }} " placeholder="hello" />      <-- this will not show placeholder 

In this case the tag between {{ }} is the variable, just make sure you are not leaving spaces between the commas because white space is also a valid character.

for 12-hours format:

SimpleDateFormat simpleDateFormatArrivals = new SimpleDateFormat("hh:mm", Locale.UK);

for 24-hours format:

SimpleDateFormat simpleDateFormatArrivals = new SimpleDateFormat("HH:mm", Locale.UK);

you make the use of the HTML Helper and have

    @using(Html.BeginForm())
    {
        Username: <input type="text" name="username" /> <br />
        Password: <input type="text" name="password" /> <br />
        <input type="submit" value="Login">
        <input type="submit" value="Create Account"/>
    }

or use the Url helper

<form method="post" action="@Url.Action("MyAction", "MyController")" >

Html.BeginForm has several (13) overrides where you can specify more information, for example, a normal use when uploading files is using:

@using(Html.BeginForm("myaction", "mycontroller", FormMethod.Post, new {enctype = "multipart/form-data"}))
{
    < ... >
}

If you don't specify any arguments, the Html.BeginForm() will create a POST form that points to your current controller and current action. As an example, let's say you have a controller called Posts and an action called Delete

public ActionResult Delete(int id)
{
   var model = db.GetPostById(id);
   return View(model);
}

[HttpPost]
public ActionResult Delete(int id)
{
    var model = db.GetPostById(id);
    if(model != null) 
        db.DeletePost(id);

    return RedirectToView("Index");
}

and your html page would be something like:

<h2>Are you sure you want to delete?</h2>
<p>The Post named <strong>@Model.Title</strong> will be deleted.</p>

@using(Html.BeginForm())
{
    <input type="submit" class="btn btn-danger" value="Delete Post"/>
    <text>or</text>
    @Url.ActionLink("go to list", "Index")
}

Litmus may help you. It will take screenshots of your webpage(s) in a wide variety of browsers so you can make sure that your site works in all of them. A free alternative (Litmus is a paid service) is Browsershots, but you do get what you pay for. (In some screenshots that Browershots returns, the browser hasn't yet finished loading the webpage...)

Of course, as other people have suggested, buying a Mac is also a good solution (and may be better, depending on the kind of testing you need to do), because then you can test your website yourself in any of the browsers that run under Mac OS X or Windows.

font-family:'Open Sans' , sans-serif;

For light: font-weight : 100; Or font-weight : lighter;

For normal: font-weight : 500; Or font-weight : normal;

For more bolder: font-weight : 900; Or font-weight : bolder;

Laravel Collection implements the PHP ArrayAccess interface (which is why using foreach is possible in the first place).

If you have the key already you can just use PHP unset.

I prefer this, because it clearly modifies the collection in place, and is easy to remember.

foreach ($collection as $key => $value) {
    unset($collection[$key]);
}

Use the below code :

from django.forms import model_to_dict

instance = Some.objects.get(slug='something')

kwargs = model_to_dict(instance, exclude=['id'])
new_instance = Some.objects.create(**kwargs)

It should work, however http://nginx.org/en/docs/http/ngx_http_core_module.html#alias says:

When location matches the last part of the directive’s value: it is better to use the root directive instead:

which would yield:

server {
  listen        8080;
  server_name   www.mysite.com mysite.com;
  error_log     /home/www-data/logs/nginx_www.error.log;
  error_page    404    /404.html;

  location /public/doc/ {
    autoindex on;
    root  /home/www-data/mysite;
  } 

  location = /404.html {
    root /home/www-data/mysite/static/html;
  }       
}

I resolved it by adding below code to my application.

// enter code here this is error I was getting when I run build.gradle. main class name has not been configured and it could not be resolved

public static void main(String[] args) {
    SpringApplication.run(Application.class, args);
}

Unless you are writing very small files, you should probably use templates.

Example:

- name: copy upstart script
  template: 
    src: myCompany-service.conf.j2 
    dest: "/etc/init/myCompany-service.conf"

I've used Blat ( http://www.blat.net/ ) for many years. It's a simple command line utility that can send email from command line. It's free and opensource.

You can use command like "Blat myfile.txt -to [email protected] -server smtp.domain.com -port 6000"

Here is some other software you can try to send email from command line (I've never used them):
http://caspian.dotconf.net/menu/Software/SendEmail/
http://www.petri.co.il/sendmail.htm
http://www.petri.co.il/software/mailsend105.zip
http://retired.beyondlogic.org/solutions/cmdlinemail/cmdlinemail.htm

Here ( http://www.petri.co.il/send_mail_from_script.htm ) you can find other various way of sending email from a VBS script, plus link to some of the mentioned software

The following VBScript code is taken from that page

Set objEmail = CreateObject("CDO.Message")
objEmail.From = "[email protected]"
objEmail.To = "[email protected]"
objEmail.Subject = "Server is down!"
objEmail.Textbody = "Server100 is no longer accessible over the network."
objEmail.Send

Save the file as something.vbs

Set Msg = CreateObject("CDO.Message")

With Msg

 .To = "[email protected]"
 .From = "[email protected]"
 .Subject = "Hello"
 .TextBody = "Just wanted to say hi."
 .Send

End With

Save the file as something2.vbs

I think these VBS scripts use the windows default mail server, if present. I've not tested these scripts...

You are looking for -H option in gnu grep.

find . -name '*bills*' -exec grep -H "put" {} \;

Here is the explanation

    -H, --with-filename
      Print the filename for each match.

I found a solution using set-url which is concise and fairly easy to understand:

1. create a new repo at Github
2. cd into the existing repository on your local machine (if you haven't cloned it yet, then do this first)
3. git remote set-url origin https://github.com/user/example.git
4. git push -u origin master

You don't need to change the delimiter to display the right part of the string with cut.

The -f switch of the cut command is the n-TH element separated by your delimiter : :, so you can just type :

 grep puddle2_1557936 | cut -d ":" -f2

Another solutions (adapt it a bit) if you want fun :

Using grep :

grep -oP 'puddle2_1557936:\K.*' <<< 'puddle2_1557936:/home/rogers.williams/folderz/puddle2'                                                                        
/home/rogers.williams/folderz/puddle2

or still with look around regex

grep -oP '(?<=puddle2_1557936:).*' <<< 'puddle2_1557936:/home/rogers.williams/folderz/puddle2'                                                                    
/home/rogers.williams/folderz/puddle2

or with perl :

perl -lne '/puddle2_1557936:(.*)/ and print $1' <<< 'puddle2_1557936:/home/rogers.williams/folderz/puddle2'                                                      
/home/rogers.williams/folderz/puddle2

or using ruby (thanks to glenn jackman)

ruby -F: -ane '/puddle2_1557936/ and puts $F[1]' <<< 'puddle2_1557936:/home/rogers.williams/folderz/puddle2'
/home/rogers.williams/folderz/puddle2

or with awk :

awk -F'puddle2_1557936:' '{print $2}'  <<< 'puddle2_1557936:/home/rogers.williams/folderz/puddle2'
/home/rogers.williams/folderz/puddle2

or with python :

python -c 'import sys; print(sys.argv[1].split("puddle2_1557936:")[1])' 'puddle2_1557936:/home/rogers.williams/folderz/puddle2'
/home/rogers.williams/folderz/puddle2

or using only bash :

IFS=: read _ a <<< "puddle2_1557936:/home/rogers.williams/folderz/puddle2"
echo "$a"
/home/rogers.williams/folderz/puddle2

or using js in a shell :

js<<EOF
var x = 'puddle2_1557936:/home/rogers.williams/folderz/puddle2'
print(x.substr(x.indexOf(":")+1))
EOF
/home/rogers.williams/folderz/puddle2

or using php in a shell :

php -r 'preg_match("/puddle2_1557936:(.*)/", $argv[1], $m); echo "$m[1]\n";' 'puddle2_1557936:/home/rogers.williams/folderz/puddle2' 
/home/rogers.williams/folderz/puddle2

Add your start class in your pom:

<properties>
    <!-- The main class to start by executing java -jar -->
    <start-class>com.mycorp.starter.HelloWorldApplication</start-class>
</properties>

or

<build>
<plugins>
    <plugin>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-maven-plugin</artifactId>             
        <configuration>    
            <mainClass>com.mycorp.starter.HelloWorldApplication</mainClass>
        </configuration>
    </plugin>
</plugins>
</build>

I kept getting the same error inspite of making the variable static. Solution: Clean Build, Clean Derived Data, Restart Xcode. Or shortcut Cmd + Shift+Alt+K

UserNotificationCenterWrapper.delegate = self

public static var delegate: UNUserNotificationCenterDelegate? {
        get {
            return UNUserNotificationCenter.current().delegate
        }
        set {
            UNUserNotificationCenter.current().delegate = newValue
        }
    }

Try this... Worked for me and printed 10/22/2013 01:37:56 AM Ofcourse this is your code only with little modifications.

final SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss");
sdf.setTimeZone(TimeZone.getTimeZone("UTC"));   // This line converts the given date into UTC time zone
final java.util.Date dateObj = sdf.parse("2013-10-22T01:37:56");

aRevisedDate = new SimpleDateFormat("MM/dd/yyyy KK:mm:ss a").format(dateObj);
System.out.println(aRevisedDate);

Basic difference between getAttribute() and getParameter() is the return type.

java.lang.Object getAttribute(java.lang.String name)
java.lang.String getParameter(java.lang.String name)

One of the Related posts gave me the (simple) answer.

Apparently the auto value on the grid-template-rows property does exactly what I was looking for.

.grid {
    display:grid;
    grid-template-columns: 1fr 1.5fr 1fr;
    grid-template-rows: auto auto 1fr 1fr 1fr auto auto;
    grid-gap:10px;
    height: calc(100vh - 10px);
}

To help guard against SQL injection, I normally try to use functions wherever possible. In this case, you could do:

...
SET @TableName = '<[db].><[schema].>tblEmployees'
SET @TableID   = OBJECT_ID(TableName) --won't resolve if malformed/injected.
...
SET @SQLQuery = 'SELECT * FROM ' + OBJECT_NAME(@TableID) + ' WHERE EmployeeID = @EmpID' 

<select name="flowers" size="5" style="height:200px">
 <option value="1">Rose</option>
 <option value="2">Tulip</option>
</select>

This simple solution allows to obtain visually a list of options, but to be able to select only one.

See responses to this question. Essentially what you are seeing is a natural consequence of using floating point arithmetic.

You could pick some arbitrary precision (significant digits of your inputs?) and round your result to it, if you feel comfortable doing that.

This works well in ASP.NET webforms.

Change the script to

<img src="' + imagePath + 'chevron-large-right-grey.gif" alt="'.....

I have a master page for each directory level and this is in the Page_Init event

  Dim vPath As String = ResolveUrl("~/Images/")
    Dim SB As New StringBuilder
    SB.Append("var imagePath = '" & vPath & "'; ")
    ScriptManager.RegisterClientScriptBlock(Me, Me.GetType(), "LoadImagePath", SB.ToString, True)

Now regardless of whether the application is run locally or deployed you get the correct full path

http://localhost:57387/Images/chevron-large-left-blue.png

I want to propose a solution where both flavors of a many-to-many configuration can be achieved.

The "catch" is we need to create a view that targets the Join Table, since EF validates that a schema's table may be mapped at most once per EntitySet.

This answer adds to what's already been said in previous answers and doesn't override any of those approaches, it builds upon them.

The model:

public class Member
{
    public int MemberID { get; set; }

    public string FirstName { get; set; }
    public string LastName { get; set; }

    public virtual ICollection<Comment> Comments { get; set; }
    public virtual ICollection<MemberCommentView> MemberComments { get; set; }
}

public class Comment
{
    public int CommentID { get; set; }
    public string Message { get; set; }

    public virtual ICollection<Member> Members { get; set; }
    public virtual ICollection<MemberCommentView> MemberComments { get; set; }
}

public class MemberCommentView
{
    public int MemberID { get; set; }
    public int CommentID { get; set; }
    public int Something { get; set; }
    public string SomethingElse { get; set; }

    public virtual Member Member { get; set; }
    public virtual Comment Comment { get; set; }
}

The configuration:

using System.ComponentModel.DataAnnotations.Schema;
using System.Data.Entity.ModelConfiguration;

public class MemberConfiguration : EntityTypeConfiguration<Member>
{
    public MemberConfiguration()
    {
        HasKey(x => x.MemberID);

        Property(x => x.MemberID).HasColumnType("int").IsRequired();
        Property(x => x.FirstName).HasColumnType("varchar(512)");
        Property(x => x.LastName).HasColumnType("varchar(512)")

        // configure many-to-many through internal EF EntitySet
        HasMany(s => s.Comments)
            .WithMany(c => c.Members)
            .Map(cs =>
            {
                cs.ToTable("MemberComment");
                cs.MapLeftKey("MemberID");
                cs.MapRightKey("CommentID");
            });
    }
}

public class CommentConfiguration : EntityTypeConfiguration<Comment>
{
    public CommentConfiguration()
    {
        HasKey(x => x.CommentID);

        Property(x => x.CommentID).HasColumnType("int").IsRequired();
        Property(x => x.Message).HasColumnType("varchar(max)");
    }
}

public class MemberCommentViewConfiguration : EntityTypeConfiguration<MemberCommentView>
{
    public MemberCommentViewConfiguration()
    {
        ToTable("MemberCommentView");
        HasKey(x => new { x.MemberID, x.CommentID });

        Property(x => x.MemberID).HasColumnType("int").IsRequired();
        Property(x => x.CommentID).HasColumnType("int").IsRequired();
        Property(x => x.Something).HasColumnType("int");
        Property(x => x.SomethingElse).HasColumnType("varchar(max)");

        // configure one-to-many targeting the Join Table view
        // making all of its properties available
        HasRequired(a => a.Member).WithMany(b => b.MemberComments);
        HasRequired(a => a.Comment).WithMany(b => b.MemberComments);
    }
}

The context:

using System.Data.Entity;

public class MyContext : DbContext
{
    public DbSet<Member> Members { get; set; }
    public DbSet<Comment> Comments { get; set; }
    public DbSet<MemberCommentView> MemberComments { get; set; }

    protected override void OnModelCreating(DbModelBuilder modelBuilder)
    {
        base.OnModelCreating(modelBuilder);

        modelBuilder.Configurations.Add(new MemberConfiguration());
        modelBuilder.Configurations.Add(new CommentConfiguration());
        modelBuilder.Configurations.Add(new MemberCommentViewConfiguration());

        OnModelCreatingPartial(modelBuilder);
     }
}

From Saluma's (@Saluma) answer

If you now want to find all comments of members with LastName = "Smith" for example you can write a query like this:

This still works...

var commentsOfMembers = context.Members
    .Where(m => m.LastName == "Smith")
    .SelectMany(m => m.MemberComments.Select(mc => mc.Comment))
    .ToList();

...but could now also be...

var commentsOfMembers = context.Members
    .Where(m => m.LastName == "Smith")
    .SelectMany(m => m.Comments)
    .ToList();

Or to create a list of members with name "Smith" (we assume there is more than one) along with their comments you can use a projection:

This still works...

var membersWithComments = context.Members
    .Where(m => m.LastName == "Smith")
    .Select(m => new
    {
        Member = m,
        Comments = m.MemberComments.Select(mc => mc.Comment)
    })
    .ToList();

...but could now also be...

var membersWithComments = context.Members
    .Where(m => m.LastName == "Smith")
    .Select(m => new
    {
        Member = m,
        m.Comments
    })
        .ToList();

If you want to remove a comment from a member

var comment = ... // assume comment from member John Smith
var member = ... // assume member John Smith

member.Comments.Remove(comment);

If you want to Include() a member's comments

var member = context.Members
    .Where(m => m.FirstName == "John", m.LastName == "Smith")
    .Include(m => m.Comments);

This all feels like syntactic sugar, however it does get you a few perks if you're willing to go through the additional configuration. Either way you seem to be able to get the best of both approaches.

As myJSON is an object you can just set its properties, for example:

myJSON.list1 = ["1","2"];

If you dont know the name of the properties, you have to use the array access syntax:

myJSON['list'+listnum] = ["1","2"];

If you want to add an element to one of the properties, you can do;

myJSON.list1.push("3");

Whether can we declare the same bean id in other xml for other reference e.x.

Servlet-Initialize.xml

<bean id="inheritedTestBean"   class="org.springframework.beans.TestBean">
  <property name="name" value="parent"/>
  <property name="age" value="1"/>
</bean>

Other xml (Document.xml)

<bean id="inheritedTestBean"  class="org.springframework.beans.Document">
  <property name="name" value="document"/>
  <property name="age" value="1"/>
</bean>

You do not include a <scope> tag in your dependency. If you add it, your dependency becomes something like:

<dependency>
     <groupId>org.openrdf.sesame</groupId>
     <artifactId>sesame-runtime</artifactId>
     <version>2.7.2</version>

The "scope" tag tells maven at which stage of the build your dependency is needed. Examples for the values to put inside are "test", "provided" or "runtime" (omit the quotes in your pom). I do not know your dependency so I cannot tell you what value to choose. Please consult the Maven documentation and the documentation of your dependency.

Simple OSM Slippy Map Demo/Example

Click on "Run code snippet" to see an embedded OpenStreetMap slippy map with a marker on it. This was created with Leaflet.

Code

// Where you want to render the map.
var element = document.getElementById('osm-map');

// Height has to be set. You can do this in CSS too.
element.style = 'height:300px;';

// Create Leaflet map on map element.
var map = L.map(element);

// Add OSM tile leayer to the Leaflet map.
L.tileLayer('http://{s}.tile.osm.org/{z}/{x}/{y}.png', {
    attribution: '&copy; <a href="http://osm.org/copyright">OpenStreetMap</a> contributors'
}).addTo(map);

// Target's GPS coordinates.
var target = L.latLng('47.50737', '19.04611');

// Set map's center to target with zoom 14.
map.setView(target, 14);

// Place a marker on the same location.
L.marker(target).addTo(map);

<script src="https://unpkg.com/[email protected]/dist/leaflet.js"></script>
<link href="https://unpkg.com/[email protected]/dist/leaflet.css" rel="stylesheet"/>
<div id="osm-map"></div>

Specs

• Uses OpenStreetMaps.
• Centers the map to the target GPS.
• Places a marker on the target GPS.
• Only uses Leaflet as a dependency.

Note:

I used the CDN version of Leaflet here, but you can download the files so you can serve and include them from your own host.

Try data-trigger="focus" instead of "click".

This solved the problem for me.

There is an OFFSET as well that should do the trick:

SELECT column FROM table
LIMIT 10 OFFSET 10

v4l support has been dropped in recent kernel versions (including the one shipped with Ubuntu 11.04).

EDIT: Your question is connected to a recent message that was sent to the OpenCV users group, which has instructions to compile OpenCV 2.2 in Ubuntu 11.04. Your approach is not ideal.

I solved in this way:

I created the 'ObjectControls' module for ThreeJS that allows you to rotate a single OBJECT (or a Group), and not the SCENE.

Include the libary:

<script src="ObjectControls.js"></script>

Usage:

var controls = new ObjectControls(camera, renderer.domElement, yourMesh);

You can find here a live demo here: https://albertopiras.github.io/threeJS-object-controls/

Here is the repo: https://github.com/albertopiras/threeJS-object-controls.

I followed around five different answers as well as all the blog posts in the previous answers and still had problems. I was trying to add a listener to some existing code that was tracing using the TraceSource.TraceEvent(TraceEventType, Int32, String) method where the TraceSource object was initialised with a string making it a 'named source'.

For me the issue was not creating a valid combination of source and switch elements to target this source. Here is an example that will log to a file called tracelog.txt. For the following code:

TraceSource source = new TraceSource("sourceName");
source.TraceEvent(TraceEventType.Verbose, 1, "Trace message");

I successfully managed to log with the following diagnostics configuration:

<system.diagnostics>
    <sources>
        <source name="sourceName" switchName="switchName">
            <listeners>
                <add
                    name="textWriterTraceListener"
                    type="System.Diagnostics.TextWriterTraceListener"
                    initializeData="tracelog.txt" />
            </listeners>
        </source>
    </sources>

    <switches>
        <add name="switchName" value="Verbose" />
    </switches>
</system.diagnostics>

$(document).on('click', 'selector', handler);

Where click is an event name, and handler is an event handler, like reference to a function or anonymous function function() {}

PS: if you know the particular node you're adding dynamic elements to - you could specify it instead of document.

Additionally, please note a.update( b ) is 2x faster than a + b

from collections import Counter
a = Counter({'menu': 20, 'good': 15, 'happy': 10, 'bar': 5})
b = Counter({'menu': 1, 'good': 1, 'bar': 3})

%timeit a + b;
## 100000 loops, best of 3: 8.62 µs per loop
## The slowest run took 4.04 times longer than the fastest. This could mean that an intermediate result is being cached.

%timeit a.update(b)
## 100000 loops, best of 3: 4.51 µs per loop

Typically you must set java.library.path on the JVM's command line:

java -Djava.library.path=/path/to/my/dll -cp /my/classpath/goes/here MainClass

select t1.*, sq.*
from table1 t1,
   (select a,b,c from table2 ...) sq
where ...

You can also do this with Portainer web application for a different visual experience.

First pull the Portainer image:

docker pull portainer/portainer

Then create a volume for Portainer:

docker volume create portainer_data

Also create a Portainer container:

docker run -d -p 8000:8000 -p 9000:9000 --name=portainer --restart=always -v /var/run/docker.sock:/var/run/docker.sock -v portainer_data:/data portainer/portainer

You will be able to access the web app with your browser at this URL: "http://localhost:9000". At the first login, you will be prompted to set your Portainer admin credentials.

In the web app, follow these menus and buttons: (Container > Add container > Fill settings > Deploy Container)

I had trouble to create a "mount" volume with Portainer and I realized I had to click "bind" when creating my container's volume. Below is an illustration of the volume binding settings that worked for my container creation with a mounted volume binded to the host.

P.S.: I'm using Docker 19.035 and Portainer 1.23.1

Use "&" instead of "&".

Recursion in Python works just as recursion in an other language, with the recursive construct defined in terms of itself:

For example a recursive class could be a binary tree (or any tree):

class tree():
    def __init__(self):
        '''Initialise the tree'''
        self.Data = None
        self.Count = 0
        self.LeftSubtree = None
        self.RightSubtree = None

    def Insert(self, data):
        '''Add an item of data to the tree'''
        if self.Data == None:
            self.Data = data
            self.Count += 1
        elif data < self.Data:
            if self.LeftSubtree == None:
                # tree is a recurive class definition
                self.LeftSubtree = tree()
            # Insert is a recursive function
            self.LeftSubtree.Insert(data)
        elif data == self.Data:
            self.Count += 1
        elif data > self.Data:
            if self.RightSubtree == None:
                self.RightSubtree = tree()
            self.RightSubtree.Insert(data)

if __name__ == '__main__':
    T = tree()
    # The root node
    T.Insert('b')
    # Will be put into the left subtree
    T.Insert('a')
    # Will be put into the right subtree
    T.Insert('c')

As already mentioned a recursive structure must have a termination condition. In this class, it is not so obvious because it only recurses if new elements are added, and only does it a single time extra.

Also worth noting, python by default has a limit to the depth of recursion available, to avoid absorbing all of the computer's memory. On my computer this is 1000. I don't know if this changes depending on hardware, etc. To see yours :

import sys
sys.getrecursionlimit()

and to set it :

import sys #(if you haven't already)
sys.setrecursionlimit()

edit: I can't guarentee that my binary tree is the most efficient design ever. If anyone can improve it, I'd be happy to hear how

The integer passed to the constructor represents its initial capacity, i.e., the number of elements it can hold before it needs to resize its internal array (and has nothing to do with the initial number of elements in the list).

To initialize an list with 60 zeros you do:

List<Integer> list = new ArrayList<Integer>(Collections.nCopies(60, 0));

If you want to create a list with 60 different objects, you could use the Stream API with a Supplier as follows:

List<Person> persons = Stream.generate(Person::new)
                             .limit(60)
                             .collect(Collectors.toList());

Additional description for John Smith's answer from the official documentation. To understand why it is.

Main host goes away

If you are adding virtual hosts to an existing web server, you must also create a block for the existing host. The ServerName and DocumentRoot included in this virtual host should be the same as the global ServerName and DocumentRoot. List this virtual host first in the configuration file so that it will act as the default host.

For example, to work properly with XAMPP, to prevent VirtualHost overriding the main host, add the follow lines into file httpd-vhosts.conf:

# Main host
<VirtualHost *:80>
    ServerName localhost
    DocumentRoot "/xampp/htdocs"
</VirtualHost>

# Additional host
<VirtualHost *:80>
    # Over directives there
</VirtualHost>

I would like to add one more thing to what the other answers have said. It is not compulsory that path will be:

C:\Users\<user>\AppData\Local\GitHub\PortableGit_<guid>\bin\git.exe

In my computer I did not found Git there.

BUT git and cmd are located in

git.exe

C:\Program Files\Git\bin\git.exe

cmd

C:\Program Files\Git\cmd

To add into PATH:

• Right-Click on My Computer
• Click on Advanced System Settings
• Click on Environment Variables
• Then, under System Variables, look for the path variable and click edit

• Add the path to git’s bin and cmd at the end of the string like this:

  ;C:\Program Files\Git\bin\git.exe;C:\Program Files\Git\cmd

OR

;C:\Users\<user>\AppData\Local\GitHub\PortableGit_<guid>\bin;C:\Users\<user>\AppData\Local\GitHub\PortableGit_<guid>\cmd

To verify, restart cmd and type git --version in cmd

I would like Web applications to not override my default shortcut keys, honestly. Ctrl+S already does something in browsers. Having that change abruptly depending on the site I'm viewing is disruptive and frustrating, not to mention often buggy. I've had sites hijack Ctrl+Tab because it looked the same as Ctrl+I, both ruining my work on the site and preventing me from switching tabs as usual.

If you want shortcut keys, use the accesskey attribute. Please don't break existing browser functionality.

You can use .is(':visible')

Selects all elements that are visible.

For example:

if($('#selectDiv').is(':visible')){

Also, you can get the div which is visible by:

$('div:visible').callYourFunction();

Live example:

console.log($('#selectDiv').is(':visible'));_x000D_
console.log($('#visibleDiv').is(':visible'));

#selectDiv {_x000D_
  display: none;  _x000D_
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<div id="selectDiv"></div>_x000D_
<div id="visibleDiv"></div>

Another example. When building a complex map of maps, the computeIfAbsent() method is a replacement for map's get() method. Through chaining of computeIfAbsent() calls together, missing containers are constructed on-the-fly by provided lambda expressions:

  // Stores regional movie ratings
  Map<String, Map<Integer, Set<String>>> regionalMovieRatings = new TreeMap<>();

  // This will throw NullPointerException!
  regionalMovieRatings.get("New York").get(5).add("Boyhood");

  // This will work
  regionalMovieRatings
    .computeIfAbsent("New York", region -> new TreeMap<>())
    .computeIfAbsent(5, rating -> new TreeSet<>())
    .add("Boyhood");

Just use the background property in your CSS.

<input id="foo" type="text" />

#foo
{
    background: url(/img/foo.png);
}

I think these both blog post should help you solving your problem.

http://blog.the-dargans.co.uk/2007/04/programmatically-adding-items-to.html http://asadewa.wordpress.com/2007/11/19/adding-a-custom-content-type-specific-item-on-a-sharepoint-list/

Short walk through:

1. Get a instance of the list you want to add the item to.

2. Add a new item to the list:

   SPListItem newItem = list.AddItem();
   

3. To bind you new item to a content type you have to set the content type id for the new item:

   newItem["ContentTypeId"] = <Id of the content type>;
   

4. Set the fields specified within your content type.

5. Commit your changes:

   newItem.Update();
   

Just wrap your WebElement into Select Object as shown below

Select dropdown = new Select(driver.findElement(By.id("identifier")));

Once this is done you can select the required value in 3 ways. Consider an HTML file like this

<html>
<body>
<select id = "designation">
<option value = "MD">MD</option>
<option value = "prog"> Programmer </option>
<option value = "CEO"> CEO </option>
</option>
</select>
<body>
</html>

Now to identify dropdown do

Select dropdown = new Select(driver.findElement(By.id("designation")));

To select its option say 'Programmer' you can do

dropdown.selectByVisibleText("Programmer ");

or

dropdown.selectByIndex(1);

or

 dropdown.selectByValue("prog");

The ISO C++ standard way to do it is to #include <iomanip> and use io manipulators like std::setw. However, that said, those io manipulators are a real pain to use even for text, and are just about unusable for formatting numbers (I assume you want your dollar amounts to line up on the decimal, have the correct number of significant digits, etc.). Even for just plain text labels, the code will look something like this for the first part of your first line:

// using standard iomanip facilities
cout << setw(20) << "Artist"
     << setw(20) << "Title"
     << setw(8) << "Price";
// ... not going to try to write the numeric formatting...

If you are able to use the Boost libraries, run (don't walk) and use the Boost.Format library instead. It is fully compatible with the standard iostreams, and it gives you all the goodness for easy formatting with printf/Posix formatting string, but without losing any of the power and convenience of iostreams themselves. For example, the first parts of your first two lines would look something like:

// using Boost.Format
cout << format("%-20s %-20s %-8s\n")  % "Artist" % "Title" % "Price";
cout << format("%-20s %-20s %8.2f\n") % "Merle" % "Blue" % 12.99;

If that is a copy/paste from your script, you've permuted this line:

#!/usr/env/bin bash

There's no #!/usr/env/bin, you meant #!/usr/bin/env.

As others have pointed out, you should use zipfile. The documentation tells you what functions are available, but doesn't really explain how you can use them to zip an entire directory. I think it's easiest to explain with some example code:

#!/usr/bin/env python
import os
import zipfile

def zipdir(path, ziph):
    # ziph is zipfile handle
    for root, dirs, files in os.walk(path):
        for file in files:
            ziph.write(os.path.join(root, file), os.path.relpath(os.path.join(root, file), os.path.join(path, '..')))
  
if __name__ == '__main__':
    zipf = zipfile.ZipFile('Python.zip', 'w', zipfile.ZIP_DEFLATED)
    zipdir('tmp/', zipf)
    zipf.close()
 

Adapted from: http://www.devshed.com/c/a/Python/Python-UnZipped/

Omit the "~\":

var path = @"FolderIcon\Folder.ico";

~\ doesn't mean anything in terms of the file system. The only place I've seen that correctly used is in a web app, where ASP.NET replaces the tilde with the absolute path to the root of the application.

You can typically assume the paths are relative to the folder where the EXE is located. Also, make sure that the image is specified as "content" and "copy if newer"/"copy always" in the properties tab in Visual Studio.

Please try it

<li>
<input id="checkid" type="checkbox" value="test" style="float: left;">
<label style="word-wrap: break-word; line-height: 16px; float: left;">testdata</label>
</li>

You should bind the tap event, the click does not exist on mobile safari or in the UIWbview. You can also use this polyfill ,to avoid the 300ms delay when a link is touched.

I don't know why your code doesn't work on chrome, but I suggest you use some workarounds :

$el.is(':visible') === $el.is(':not(:hidden)');

or

$el.is(':visible') === !$el.is(':hidden');  

If you are certain that jQuery gives you some bad results in chrome, you can just rely on the css rule checking :

if($el.css('display') !== 'none') {
    // i'm visible
}

Plus, you might want to use the latest jQuery because it might have bugs from older version fixed.

You either need to create an object of type Beta in the Alpha class or its method

Like you do here in the Main Beta cBeta = new Beta();

If you want to use the variable you create in your Main then you have to parse it to cAlpha as a parameter by making the Alpha constructor look like

public class Alpha 
{

    Beta localInstance;

    public Alpha(Beta _beta)
    {
        localInstance = _beta;
    }


     public void DoSomethingAlpha() 
     {
          localInstance.DoSomethingAlpha();     
     }
}

That is an object, not an array. So you would do:

var json = { cool: 34.33, alsocool: 45454 };
json.supercool = 3.14159;
console.dir(json);

Just use a compiler (or provide it with the arguments it needs) such that it compiles for a more recent version of the C standard, C99 or C11. E.g for the GCC family of compilers that would be -std=c99.

    <br>

                    connection = DriverManager.getConnection(connectionUrl + database, userid, password);
                    statement = connection.createStatement();
                    String sql = "select * from track where track_id="+ id;
                    resultSet = statement.executeQuery(sql);
                    while (resultSet.next()) {

                    connection.close();
                } catch (Exception e) {
                    e.printStackTrace();

As MaxPRafferty mentioned:

Just a note to anyone landing here from google, the answers setting path are all correct, but this problem probably stems from not giving the python installer administrative rights it needs to set the path itself. An alternative may be to simply right click the installer and select run as administrator, then repair the installation. If that still doesn't work, choose the [Environment] answer below that corresponds to your python version and installation directory. – MaxPRafferty Nov 18 '15 at 20:06

Maybe it is wise to let Python installer to add the path itself. The trap here is that by default Python installer does NOT add path for you. You should look carefully (by scrolling down to see what has been installed) during the installation process instead of directly nexting to the end.

What he missed saying is that you cannot run as administrator once you have installed it. Uninstall and reinstall may do, but the simplest is to right click and Troubleshoot compatibility, being careful this time to check the 'add path' in the "what to install" dialog before hiting next. Then restart powershell. Voilà. It works for me.

First set Storage Engine as InnoDB

Set the html tag, too. This way no weird position hacks are required.

Relative path:

ConnectionString = "Data Source=|DataDirectory|\Database.sdf";

Modifying DataDirectory as executable's path:

string executable = System.Reflection.Assembly.GetExecutingAssembly().Location;
string path = (System.IO.Path.GetDirectoryName(executable));
AppDomain.CurrentDomain.SetData("DataDirectory", path);

What you can do and what you should do are different matters.

If the list is very short, or you are only ever going to call find once then use the linear approach above.

However linear-search is one of the biggest evils I find in slow code, and consider using an ordered collection (set or multiset if you allow duplicates). If you need to keep a list for other reasons eg using an LRU technique or you need to maintain the insertion order or some other order, create an index for it. You can actually do that using a std::set of the list iterators (or multiset) although you need to maintain this any time your list is modified.

Table structure...very basic:

create table tabla(ID int, Stuff varchar (50));

insert into tabla values(1, '32.43');
insert into tabla values(2, '43.33');
insert into tabla values(3, '23.22');

Query:

SELECT SUM(cast(Stuff as decimal(4,2))) as result FROM tabla

Or, try this:

SELECT SUM(cast(isnull(Stuff,0) as decimal(12,2))) as result FROM tabla

You can see above that update-alternatives is run to set up links for the various Java binaries.

After this install, there are also links in /usr/bin, links in /etc/alternatives, and files for each binary in /var/lib/dpkg/alternatives.

ls -l /usr/bin/java /etc/alternatives/java /var/lib/dpkg/alternatives/java
lrwxrwxrwx 1 root root  40 2013-01-16 14:44 /etc/alternatives/java -> /usr/lib/jvm/java-6-openjdk/jre/bin/java

Let's contast this with installing without purging.

As you see, update-alternatives is not triggered.

After this install, there are no files for the Java binaries in /var/lib/dpkg/alternatives, no links in /etc/alternatives, and no links in /usr/bin.

The removal of the files in /var/lib/dpkg/alternatives also breaks update-java-alternatives.

The below both ways works fine.

System.out.println("The Class Name is: " + this.getClass().getName());

Usually a good place to start when you run into problems is the manual. The page on configuring email explains that there's a big difference between the PHP mail command running on MSWindows and on every other operating system; it's a good idea when posting a question to provide relevant information on how that part of your system is configured and what operating system it is running on.

Your PHP is configured to talk to an SMTP server - the default for an MSWindows machine, but either you have no MTA installed or it's blocking connections. While for a commercial website running your own MTA robably comes quite high on the list of things to do, it is not a trivial exercise - you really need to know what you're doing to get one configured and running securely. It would make a lot more sense in your case to use a service configured and managed by someone else.

Since you'll be connecting to a remote MTA using a gmail address, then you should probably use Gmail's server; you will need SMTP authenticaton and probably SSL support - neither of which are supported by the mail() function in PHP. There's a simple example here using swiftmailer with gmail or here's an example using phpmailer

this does not affect resulting code - it is compilation time operator and the code generated with or without it will be the same. When you have to use it, depends on context. For example you have to use it, as you said, when you have local variable that shadows class variable and you want refer to class variable and not local one.

edit: by "resulting code will be the same" I mean of course, when some variable in local scope doesn't hide the one belonging to class. Thus

class POJO {
   protected int i;

   public void modify() {
      i = 9;
   }

   public void thisModify() {
      this.i = 9;
   }
}

resulting code of both methods will be the same. The difference will be if some method declares local variable with the same name

  public void m() {
      int i;
      i = 9;  // i refers to variable in method's scope
      this.i = 9; // i refers to class variable
  }

This should actually do what the OP specifies:

One-liner in Bash:

$ for first_level in `find . -maxdepth 1 -type d`; do find $first_level -printf "%TY-%Tm-%Td %TH:%TM:%TS $first_level\n" | sort -n | tail -n1 ; done

which gives output such as:

2020-09-12 10:50:43.9881728000 .
2020-08-23 14:47:55.3828912000 ./.cache
2018-10-18 10:48:57.5483235000 ./.config

2020-08-23 14:48:19.6171696000 ./.local
2020-08-23 14:24:17.9773605000 ./.nano

This lists each first-level directory with the human-readable timestamp of the latest file within those folders, even if it is in a subfolder, as requested in

"I need to make a list of all these directories that is constructed in a way such that every first-level directory is listed next to the date and time of the latest created/modified file within it."

If you use a List<T>, you can also use this code:

List<string> list = new List<string>();
list.Add("1");
list.Add("2");
list.Add("3");
list.Reverse();

This is a method that write the list reverse in itself.

Now the foreach:

foreach(string s in list)
{
    Console.WriteLine(s);
}

The output is:

3
2
1

You can use python within the bash script too. I didn't have much success with some of the top answers here, and found this to work without the need for loops:

#!/bin/bash
python
filetosearch = '/home/ubuntu/ip_table.txt'
texttoreplace = 'tcp443'
texttoinsert = 'udp1194'

s = open(filetosearch).read()
s = s.replace(texttoreplace, texttoinsert)
f = open(filetosearch, 'w')
f.write(s)
f.close()
quit()

For me, it was skype causing the problem. Once I stopped skype, everything worked. I have 1.7.1 xampp (mysql and apache) running on Windows 7 x64.

string message = null;
//reset the password
var result = await IdentityManager.Passwords.ResetPasswordAsync(model.Token, model.Password);
if (result.Success)
{
    message = "The password has been reset.";
    return RedirectToAction("PasswordResetCompleted", new { message = message });
}
else
{
    AddErrors(result);
}

This snippet of code is taken out of the AspNetIdentitySample project available on github

If you do "git status" while having a merge conflict, the first thing git shows you is how to abort the merge.

If you want to do it in multiple, easy-to-remember commands:

1. list stopped containers:

docker ps -a

2. copy the name or the container id of the container you want to attach to, and start the container with:

docker start -i <name/id>

The -i flag tells docker to attach to the container's stdin.

If the container wasn't started with an interactive shell to connect to, you need to do this to run a shell:

docker start <name/id>
docker exec -it <name/id> /bin/sh

The /bin/sh is the shell usually available with alpine-based images.

View(function_name) - eg. View(mean) Make sure to use uppercase [V]. The read-only code will open in the editor.

We do it differently. IMHO we do it in an easier way: in master we are working on the next major version.

Each larger feature gets its own branch (derived from master) and will be rebased (+ force pushed) on top of master regularly by the developer. Rebasing only works fine if a single developer works on this feature. If the feature is finished, it will be freshly rebased onto master and then the master fast-forwarded to the latest feature commit.

To avoid the rebasing/forced push one also can merge master changes regularly to the feature branch and if it's finished merge the feature branch into master (normal merge or squash merge). But IMHO this makes the feature branch less clear and makes it much more difficult to reorder/cleanup the commits.

If a new release is coming, we create a side-branch out of master, e.g. release-5 where only bugs get fixed.

There does exist a split function based on regular expressions. It's not listed in the tutorial, but it is listed on the language manual on the wiki:

split(string str, string pat)
   Split str around pat (pat is a regular expression) 

In your case, the delimiter "|" has a special meaning as a regular expression, so it should be referred to as "\\|".

There isn't an elegant way in vanilla Java.

Google Guava

The Google Guava library is great - check out their Iterables class. This method will throw a NoSuchElementException if the list is empty, as opposed to an IndexOutOfBoundsException, as with the typical size()-1 approach - I find a NoSuchElementException much nicer, or the ability to specify a default:

lastElement = Iterables.getLast(iterableList);

You can also provide a default value if the list is empty, instead of an exception:

lastElement = Iterables.getLast(iterableList, null);

or, if you're using Options:

lastElementRaw = Iterables.getLast(iterableList, null);
lastElement = (lastElementRaw == null) ? Option.none() : Option.some(lastElementRaw);

You can fire an event yourself in ngOnInit() of your Angular root component and then listen for this event outside of Angular.

This is Dart code (I don't know TypeScript) but should't be to hard to translate

@Component(selector: 'app-element')
@View(
    templateUrl: 'app_element.html',
)
class AppElement implements OnInit {
  ElementRef elementRef;
  AppElement(this.elementRef);

  void ngOnInit() {
    DOM.dispatchEvent(elementRef.nativeElement, new CustomEvent('angular-ready'));
  }
}

I wanted to add a method which I think was simplest of all.

1. Simply right click the pfx file, click "Install" follow the wizard, and add it to a store (I added to the Personal store).

2. In start menu type certmgr.msc and go to CertManager program.

3. Find your pfx certificate (tabs at top are the various stores), click the export button and follow the wizard (there is an option to export as .CER)

Essentially it does the same thing as Andrew's answer, but it avoids using Windows Management Console (goes straight to the import/export).

the one easy way to do it is to open Excel create sheet containing test data you want to export then say to excel save as xml open the xml see the xml format excel is expecting and generate it by head replacing the test data with export data

The problem is that the CASE statement won't work in the way you're trying to use it. You can only use it to switch the value of one field in a query. If I understand what you're trying to do, you might need this:

SELECT 
   ActivityID,
   FieldName = CASE 
                  WHEN ActivityTypeID <> 2 THEN
                      (Some Aggregate Sub Query)
                  ELSE
                     (Some Aggregate Sub Query with diff result)
               END,
   FieldName2 = CASE
                  WHEN ActivityTypeID <> 2 THEN
                      (Some Aggregate Sub Query)
                  ELSE
                     (Some Aggregate Sub Query with diff result)
               END

Try this solution.

$mainModelData = mainModel::where('column', $value)
    ->join('relationModal', 'main_table_name.relation_table_column', '=', 'relation_table.id')
    ->orderBy('relation_table.title', 'ASC')
    ->with(['relationModal' => function ($q) {
        $q->where('column', 'value');
    }])->get();

Example:

$user = User::where('city', 'kullu')
    ->join('salaries', 'users.id', '=', 'salaries.user_id')
    ->orderBy('salaries.amount', 'ASC')
    ->with(['salaries' => function ($q) {
        $q->where('amount', '>', '500000');
    }])->get();

You can change the column name in join() as per your database structure.

you can use lst.pop() or del lst[-1]

pop() removes and returns the item, in case you don't want have a return use del

You can update your python version to 3.8 in conda using the command

conda install -c anaconda python=3.8

as per https://anaconda.org/anaconda/python. Though not all packages support 3.8 yet, running

conda update --all

may resolve some dependency failures. You can also create a new environment called py38 using this command

conda create -n py38 python=3.8

Edit - note that the conda install option will potentially take a while to solve the environment, and if you try to abort this midway through you will lose your Python installation (usually this means it will resort to non-conda pre-installed system Python installation).

For SQL Server 2005 upwards:

SELECT [name] AS [TableName], [create_date] AS [CreatedDate] FROM sys.tables

For SQL Server 2000 upwards:

SELECT so.[name] AS [TableName], so.[crdate] AS [CreatedDate]
FROM INFORMATION_SCHEMA.TABLES AS it, sysobjects AS so 
WHERE it.[TABLE_NAME] = so.[name]

Here's a Boolean thing:

but

if not (suffix == "flac"  or suffix == "cue" ):     # CORRECT!
       print  filename + ' is not a flac or cue file'

(not a) or (not b) == not ( a and b ) , is false only if a and b are both true

not (a or b) is true only if a and be are both false.

Solution 1 - Using VirtualBox

As Muhammad Sahputra suggested in this post, it is possible to run Windows OS inside VirtualBox (using VBoxHeadless - without graphical interface) inside Docker container.

Also, a NAT setup inside the VM network configurations can do a port forwarding which gives you the ability to pass-through any traffic that comes to and from the Docker container. This eventually, in a wide perspective, allows you to run any Windows-based service on top of Linux machine.

Maybe this is not a typical use-case of a Docker container, but it definitely an interesting approach to the problem.

Solution 2 - Using Wine

For simple applications and maybe more complicated, you can try to use wine inside a docker container.

This docker hub page may help you to achieve your goal.

I hope that Docker will release a native solution soon, like they did with docker-machine on Windows several years ago.

You can do it without having to create a real Hibernate mapping. Try this:

SELECT * FROM Employee e, Team t WHERE e.Id_team=t.Id_team

If I get your question correctly, you could do something like this.

>>> import matplotlib.pyplot as plt
>>> testList =[(0, 6.0705199999997801e-08), (1, 2.1015700100300739e-08), 
 (2, 7.6280656623374823e-09), (3, 5.7348209304555086e-09), 
 (4, 3.6812203579604238e-09), (5, 4.1572516753310418e-09)]
>>> from math import log
>>> testList2 = [(elem1, log(elem2)) for elem1, elem2 in testList]

>>> zip(*testList2)
[(0, 1, 2, 3, 4, 5), (-16.617236475334405, -17.67799605473062, -18.691431541177973, -18.9767093108359, -19.420021520728017, -19.298411635970396)]
>>> plt.scatter(*zip(*testList2))
>>> plt.show()

which would give you something like

Or as a line plot,

>>> plt.plot(*zip(*testList2))
>>> plt.show()

EDIT - If you want to add a title and labels for the axis, you could do something like

>>> plt.scatter(*zip(*testList2))
>>> plt.title('Random Figure')
>>> plt.xlabel('X-Axis')
>>> plt.ylabel('Y-Axis')
>>> plt.show()

which would give you

Math.abs(num) => Always positive
-Math.abs(num) => Always negative

You do realize however, that for your code

if($this.find('.pdxslide-activeSlide').index() < slideNum-1){ slideNum = -slideNum }
console.log(slideNum)

If the index found is 3 and slideNum is 3,
then 3 < 3-1 => false
so slideNum remains positive??

It looks more like a logic error to me.

You can use requests-html which will download and use chromium underneath.

3. Get their row handles from grid (Note here grid is already updated with new rows)
4. Checking if the row handle is valid or not.
5. When valid row handle then select it.

Where itemList is list of rows to be selected in the grid view.

In function post():

todo.author = users.get_current_user()

So, to get str(todo.author), you need str(users.get_current_user()). What is returned by get_current_user() function ?

If it is an object, check does it contain a str()" function?

I think the error lies there.

I wrote a relatively simple answer for this.

I have a table that's using one of the "sticky table header" plugins to stick right below a particular div on my page, but the menu to the left of the table didn't stick (as it's not part of the table.)

For my purposes, I knew the div that needed "stickiness" was always going to start at 385 pixels below the top of the window, so I created an empty div right above that:

<div id="stopMenu" class="stopMenu"></div>

Then ran this:

$(window).scroll(function(){   
   if ( $(window).scrollTop() > 385 ) {
    extraPadding = $(window).scrollTop() - 385;
    $('#stopMenu').css( "padding-top", extraPadding );
   } else {
     $('#stopMenu').css( "padding-top", "0" );
   }
});

As the user scrolls, it adds whatever the value of $(window).scrollTop() is to the integer 385, then adds that value to the stopMenu div that's above the thing I want to stay focused.

In the event the user scrolls all the way back up, I just set the extra padding to 0.

This doesn't require the user to do anything IN CSS particularly, but it's kind of a nice effect to make a small delay, so I put the class="stopMenu" in as well:

.stopMenu {
  .transition: all 0.1s;
}

The best format to use is "yyyy'-'MM'-'dd'T'HH':'mm':'ss'.'fffK".

The last K on string will be changed to 'Z' if the date is UTC or with timezone (+-hh:mm) if is local. (http://msdn.microsoft.com/en-us/library/8kb3ddd4.aspx)

As LukeH said, is good to use the ToUniversalTime if you want that all the dates will be UTC.

The final code is:

string foo = yourDateTime.ToUniversalTime()
                         .ToString("yyyy'-'MM'-'dd'T'HH':'mm':'ss'.'fffK");

Since itunesconnect has been changed i am updating with the new steps here.

You have to follow through these steps

1. Login to itunesconnect
2. Choose your app in My Apps section
3. Under Appstore tab choose "Pricing and Availability"

Not really an answer to your question as asked, but thought I'd chip in about your general objective.

There already is a method to generate random file names in .NET.

See System.Path.GetTempFileName and GetRandomFileName.

Alternatively, it is a common practice to use a GUID to name random files.

In my case, I just restarted the docker and just worked.

first search for tabs in your file : /^I :set expandtab :retab

will work.

I found this on google, but I don't want to use XStream, because it causes to much overhead in my environment. I only needed to parse a file and since I did not find anything I like I created my own simple solution for parsing a file of the format that you describe. So here is my solution:

public class XmlToMapUtil {
    public static Map<String, String> parse(InputSource inputSource) throws SAXException, IOException, ParserConfigurationException {
        final DataCollector handler = new DataCollector();
        SAXParserFactory.newInstance().newSAXParser().parse(inputSource, handler);
        return handler.result;
    }

    private static class DataCollector extends DefaultHandler {
        private final StringBuilder buffer = new StringBuilder();
        private final Map<String, String> result = new HashMap<String, String>();

        @Override
        public void endElement(String uri, String localName, String qName) throws SAXException {
            final String value = buffer.toString().trim();
            if (value.length() > 0) {
                result.put(qName, value);
            }
            buffer.setLength(0);
        }

        @Override
        public void characters(char[] ch, int start, int length) throws SAXException {
            buffer.append(ch, start, length);
        }
    }
}

Here are a couple of TestNG+FEST Assert Tests:

public class XmlToMapUtilTest {

    @Test(dataProvider = "provide_xml_entries")
    public void parse_returnsMapFromXml(String xml, MapAssert.Entry[] entries) throws Exception {
        // execution
        final Map<String, String> actual = XmlToMapUtil.parse(new InputSource(new StringReader(xml)));

        // evaluation
        assertThat(actual)
            .includes(entries)
            .hasSize(entries.length);
    }

    @DataProvider
    public Object[][] provide_xml_entries() {
        return new Object[][]{
                {"<root />", new MapAssert.Entry[0]},

                {
                    "<root><a>aVal</a></root>", new MapAssert.Entry[]{
                            MapAssert.entry("a", "aVal")
                    },
                },

                {
                    "<root><a>aVal</a><b>bVal</b></root>", new MapAssert.Entry[]{
                            MapAssert.entry("a", "aVal"),
                            MapAssert.entry("b", "bVal")
                    },
                },

                {
                    "<root> \t <a>\taVal </a><b /></root>", new MapAssert.Entry[]{
                            MapAssert.entry("a", "aVal")
                    },
                },
        };
    }
}

I had the same problem. If I add one Environment.Newline I get one new line in the textbox. But if I add two Environment.Newline I get one new line. In my web app I use a whitespace modul that removes all unnecessary white spaces. If i disable this module I get two new lines in my textbox. Hope that helps.

Great answer above. Another way is to use the great yaml jq wrapper tool, yq at https://github.com/kislyuk/yq

Save your JSON example to a file, say ex.json and then

yq -y '.' ex.json

Some Android phones contain Busybox. Was hard to find.

To see if busybox was around:

ls -lR / | grep busybox

If you know it's around. You need some read/write space. Try you flash drive, /sdcard

cd /sdcard
ls -lR / >lsoutput.txt

upload to your computer. Upload the file. Get some text editor. Search for busybox. Will see what directory the file was found in.

busybox find /sdcard -iname 'python*'

to make busybox easier to access, you could:

cd /sdcard
ln -s /where/ever/busybox/is  busybox
/sdcard/busybox find /sdcard -iname 'python*'

Or any other place you want. R

Solution without need of regular expression:

string ExtractString(string s, string tag) {
     // You should check for errors in real-world code, omitted for brevity
     var startTag = "<" + tag + ">";
     int startIndex = s.IndexOf(startTag) + startTag.Length;
     int endIndex = s.IndexOf("</" + tag + ">", startIndex);
     return s.Substring(startIndex, endIndex - startIndex);
}

README.md or .mkdn or .markdown denotes that the file is markdown formatted. Markdown is a markup language. With it you can easily display headers or have italic words, or bold or almost anything that can be done to text

For some reason, the above answer did not work for me; I did not return to the command prompt after running it as I expected with the trailing &. Instead, I simply tried with

nohup some_command > nohup2.out&

and it works just as I want it to. Leaving this here in case someone else is in the same situation. Running Bash 4.3.8 for reference.

Note that if you're using the IBM JDK you may also have to set

You can use the curses.h library in linux as mentioned in the other answer.

You can install it in Ubuntu by:

sudo apt-get update

sudo apt-get install ncurses-dev

I took the installation part from here.

A simple way to do it without the use of such a complicated draw statement:

    //Make a backup so that we can reset our graphics object after using it.
    AffineTransform backup = g2d.getTransform();
    //rx is the x coordinate for rotation, ry is the y coordinate for rotation, and angle
    //is the angle to rotate the image. If you want to rotate around the center of an image,
    //use the image's center x and y coordinates for rx and ry.
    AffineTransform a = AffineTransform.getRotateInstance(angle, rx, ry);
    //Set our Graphics2D object to the transform
    g2d.setTransform(a);
    //Draw our image like normal
    g2d.drawImage(image, x, y, null);
    //Reset our graphics object so we can draw with it again.
    g2d.setTransform(backup);

$.post does not work if you have CORS (Cross Origin Resource Sharing) issue. Try to use $.ajax in following format:

$.ajax({
        url: someurl,
        contentType: 'application/json',
        data: requestInJSONFormat,
        headers: { 'Access-Control-Allow-Origin': '*' },
        dataType: 'json',
        type: 'POST',
        async: false,
        success: function (Data) {...}
});

only variable/object declaration statement are written outside of method

public class details{
    public static void main(String arg[]){
        BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
        System.out.println("What is your name?");
        String name = in.readLine(); ;
        System.out.println("Hello " + name);
    }
}

here is example try to learn java book and see the syntax then try to develop the program

Here is how you can add an icon while creating an exe file from a Python file

• open command prompt at the place where Python file exist

• type:

  pyinstaller --onefile -i"path of icon"  path of python file
  

Example-

pyinstaller --onefile -i"C:\icon\Robot.ico" C:\Users\Jarvis.py

This is the easiest way to add an icon.

The MediaStore API is probably throwing away the alpha channel (i.e. decoding to RGB565). If you have a file path, just use BitmapFactory directly, but tell it to use a format that preserves alpha:

BitmapFactory.Options options = new BitmapFactory.Options();
options.inPreferredConfig = Bitmap.Config.ARGB_8888;
Bitmap bitmap = BitmapFactory.decodeFile(photoPath, options);
selected_photo.setImageBitmap(bitmap);

As an aside to those that stumble along across this, one nice way to run test level on using the HostingEnvironment call, is if accessing say a UNC share: \example\ that is mapped to ~/example/ you could execute this to get around IIS-Express issues:

#if DEBUG
    var fs = new FileStream(@"\\example\file",FileMode.Open, FileAccess.Read);
#else
    var fs = new FileStream(HostingEnvironment.MapPath("~/example/file"), FileMode.Open, FileAccess.Read);
#endif

I find that helpful in case you have rights to locally test on a file, but need the env mapping once in production.

I compared the suggested alternatives for speed and found that, for large enough vectors/matrices to fill, all alternatives except val * ones and array(n * [val]) are equally fast.

Code to reproduce the plot:

import numpy
import perfplot

val = 42.0


def fill(n):
    a = numpy.empty(n)
    a.fill(val)
    return a


def colon(n):
    a = numpy.empty(n)
    a[:] = val
    return a


def full(n):
    return numpy.full(n, val)


def ones_times(n):
    return val * numpy.ones(n)


def list(n):
    return numpy.array(n * [val])


perfplot.show(
    setup=lambda n: n,
    kernels=[fill, colon, full, ones_times, list],
    n_range=[2 ** k for k in range(20)],
    logx=True,
    logy=True,
    xlabel="len(a)",
)

Is there an easy way to do this in Java? The java.util.Date class seems rather limited.

Here is my quick and dirty Java solution:

import java.util.Date;
import javax.management.timer.Timer;

String getRelativeDate(Date date) {     
  long delta = new Date().getTime() - date.getTime();
  if (delta < 1L * Timer.ONE_MINUTE) {
    return toSeconds(delta) == 1 ? "one second ago" : toSeconds(delta) + " seconds ago";
  }
  if (delta < 2L * Timer.ONE_MINUTE) {
    return "a minute ago";
  }
  if (delta < 45L * Timer.ONE_MINUTE) {
    return toMinutes(delta) + " minutes ago";
  }
  if (delta < 90L * Timer.ONE_MINUTE) {
    return "an hour ago";
  }
  if (delta < 24L * Timer.ONE_HOUR) {
    return toHours(delta) + " hours ago";
  }
  if (delta < 48L * Timer.ONE_HOUR) {
    return "yesterday";
  }
  if (delta < 30L * Timer.ONE_DAY) {
    return toDays(delta) + " days ago";
  }
  if (delta < 12L * 4L * Timer.ONE_WEEK) { // a month
    long months = toMonths(delta); 
    return months <= 1 ? "one month ago" : months + " months ago";
  }
  else {
    long years = toYears(delta);
    return years <= 1 ? "one year ago" : years + " years ago";
  }
}

private long toSeconds(long date) {
  return date / 1000L;
}

private long toMinutes(long date) {
  return toSeconds(date) / 60L;
}

private long toHours(long date) {
  return toMinutes(date) / 60L;
}

private long toDays(long date) {
  return toHours(date) / 24L;
}

private long toMonths(long date) {
  return toDays(date) / 30L;
}

private long toYears(long date) {
  return toMonths(date) / 365L;
}

For those wanting to explicitly declare they are pulling from dockerhub when using fabric8 maven plugin, add a new property: <docker.pull.registry>registry.hub.docker.com/library</docker.pull.registry>

I arrived on this page trying to solve problem of pulling from my AWS ECR registry when building Docker images using fabric8.

Nikl's version doesn't pass get query parameters, I used the following modified version:

window.location.href = window.location.protocol +'//'+ window.location.host + window.location.pathname + window.location.search;

or in my case I needed to refresh the topmost page\frame, so I used the following version

window.top.location.href = window.top.location.protocol +'//'+ window.top.location.host + window.top.location.pathname + window.top.location.search;

When you just want to do a try catch without handling the exception, how do you do it in Python?

This will help you to print what the exception is:( i.e. try catch without handling the exception and print the exception.)

import sys
try:
    doSomething()
except:
    print "Unexpected error:", sys.exc_info()[0]

You need to remove the static from your accessor methods - these methods need to be instance methods and access the instance variables

public class IDCard {
    public String name, fileName;
    public int id;

    public IDCard(final String name, final String fileName, final int id) {
        this.name = name;
        this.fileName = fileName
        this.id = id;
    }

    public String getName() {
        return name;
    }
}

You can the create an IDCard and use the accessor like this:

final IDCard card = new IDCard();
card.getName();

Each time you call new a new instance of the IDCard will be created and it will have it's own copies of the 3 variables.

If you use the static keyword then those variables are common across every instance of IDCard.

A couple of things to bear in mind:

1. don't add useless comments - they add code clutter and nothing else.
2. conform to naming conventions, use lower case of variable names - name not Name.

await blob.arrayBuffer() is good.

The problem is when iOS / Safari support is needed.. for that one would need this:

Blob.prototype.arrayBuffer ??=function(){ return new Response(this).arrayBuffer() }

try to empty your innerHtml everytime. just like this:

curl_getinfo() must be added before closing the curl handler

import difflib

lines1 = '''

'''.strip().splitlines()

# Changes:

# changed gophers to gopher
# removed hound
# added mouse

for line in difflib.unified_diff(lines1, lines2, fromfile='file1', tofile='file2', lineterm=''):
    print line

Outputs the following:

--- file1
+++ file2
@@ -1,7 +1,7 @@
+cat
 dog
-cat
 bird
 buffalo
-gophers
-hound
+gopher
 horse
+mouse

This diff gives you context -- surrounding lines to help make it clear how the file is different. You can see "cat" here twice, because it was removed from below "dog" and added above it.

You can use n=0 to remove the context.

for line in difflib.unified_diff(lines1, lines2, fromfile='file1', tofile='file2', lineterm='', n=0):
    print line

Outputting this:

--- file1
+++ file2
@@ -0,0 +1 @@
+cat
@@ -2 +2,0 @@
-cat
@@ -5,2 +5 @@
-gophers
-hound
+gopher
@@ -7,0 +7 @@
+mouse

But now it's full of the "@@" lines telling you the position in the file that has changed. Let's remove the extra lines to make it more readable.

for line in difflib.unified_diff(lines1, lines2, fromfile='file1', tofile='file2', lineterm='', n=0):
    for prefix in ('---', '+++', '@@'):
        if line.startswith(prefix):
            break
    else:
        print line

Giving us this output:

+cat
-cat
-gophers
-hound
+gopher
+mouse

Now what do you want it to do? If you ignore all removed lines, then you won't see that "hound" was removed. If you're happy just showing the additions to the file, then you could do this:

diff = difflib.unified_diff(lines1, lines2, fromfile='file1', tofile='file2', lineterm='', n=0)
lines = list(diff)[2:]
added = [line[1:] for line in lines if line[0] == '+']
removed = [line[1:] for line in lines if line[0] == '-']

print 'additions:'
for line in added:
    print line
print
print 'additions, ignoring position'
for line in added:
    if line not in removed:
        print line

Outputting:

additions:
cat
gopher
mouse

additions, ignoring position:
gopher
mouse

You can probably tell by now that there are various ways to "print the differences" of two files, so you will need to be very specific if you want more help.

This is discouraged (if you want to create/distribute a clean Docker image), since the PATH variable is set by /etc/profile script, the value can be overridden.

head /etc/profile:

if [ "`id -u`" -eq 0 ]; then
  PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin"
else
  PATH="/usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/games"
fi
export PATH

At the end of the Dockerfile, you could add:

RUN echo "export PATH=$PATH" > /etc/environment

So PATH is set for all users.

I use this JS snippet code :

First of all, I reach all the classes then according to index of my target class, I set className = "".

Target = document.getElementsByClassName("yourClass")[1];
Target.className="";

I am not sure whether the database backup file, you trying to restore, is coming from the same environment as you trying to restore it onto.

Remember that destination path of .mdf and .ldf files lives with the backup file itself.

If this is not a case, that means the backup file is coming from a different environment from your current hosting one, make sure that .mdf and .ldf file path is the same (exists) as on your machine, relocate these otherwise. (Mostly a case of restoring db in Docker image)

The way how to do it: In Databases -> Restore database -> [Files] option -> (Check "Relocate all files to folder" - mostly default path is populated on your hosting environment already)

There are two ways to achieve this:

final PageRequest page1 = new PageRequest(
  0, 20, Direction.ASC, "lastName", "salary"
);

final PageRequest page2 = new PageRequest(
  0, 20, new Sort(
    new Order(Direction.ASC, "lastName"), 
    new Order(Direction.DESC, "salary")
  )
);

dao.findAll(page1);

As you can see the second form is more flexible as it allows to define different direction for every property (lastName ASC, salary DESC).

try this.

table 
{
    background-color: #aaa;
}

tbody 
{
    background-color: #ddd;
    height: 100px;
    overflow-y: scroll;
    position: absolute;
}

td 
{
    padding: 3px 10px;
    color: green;
    width: 100px;
}

You might want to :

• Check that auto-commit is off
• Open Connection
• Send multiple batches of inserts in a single transaction (size of about 4000-10000 rows ? you see)
• Close connection

Depending on how well your server scales (its definitively ok with PostgreSQl, Oracle and MSSQL), do the thing above with multiple threads and multiple connections.

If the whole purpose is to communicate data with some other application, use Intent's sendBroadcast methods.

Swift 4 with customType:

let button = UIButton(frame: aRectHere)
    let buttonImage = UIImage(named: "imageName")
    button.setImage(buttonImage?.withRenderingMode(.alwaysTemplate), for: .normal)
    button.tintColor = .white

…just because this method hasn't been mentioned so far - open the console and type:

$ === jQuery

As @Juhana mentioned above $().jquery will return the version number.

An alternative solution is to use a wrapper for the String, for instances this:

public class StringResponse {
    private String response;
    public StringResponse(String response) {
        this.response = response;
    }
    public String getResponse() {
        return response;
    }
}

Then return this in your controller's methods:

ResponseEntity<StringResponse>

I've reworked VonC's script to do everything automatically and not ask me for anything. You give it two commit SHA1s and it will squash everything between them into one commit named "squashed history":

#!/bin/sh
# Go back to the last commit that we want
# to form the initial commit (detach HEAD)
git checkout $2

# reset the branch pointer to the initial commit (= $1),
# but leaving the index and working tree intact.
git reset --soft $1

# amend the initial tree using the tree from $2
git commit --amend -m "squashed history"

# remember the new commit sha1
TARGET=`git rev-list HEAD --max-count=1`

# go back to the original branch (assume master for this example)
git checkout master

# Replay all the commits after $2 onto the new initial commit
git rebase --onto $TARGET $2

Just as zero is a number - just a number that represents none - an empty list is still a list, just a list with nothing in it. null is no list at all; it's therefore different from an empty list.

Similarly, a list that contains null items is a list, and is not an empty list. Because it has items in it; it doesn't matter that those items are themselves null. As an example, a list with three null values in it, and nothing else: what is its length? Its length is 3. The empty list's length is zero. And, of course, null doesn't have a length.

in Frag1:

Bundle b = new Bundle();

b.putStringArray("arrayname that use to retrive in frag2",StringArrayObject);

Frag2.setArguments(b);

in Frag2:

Bundle b = getArguments();

String[] stringArray = b.getStringArray("arrayname that passed in frag1");

It's that simple.

Another simple routine.

def flatten_columns(df, sep='.'):
    def _remove_empty(column_name):
        return tuple(element for element in column_name if element)
    def _join(column_name):
        return sep.join(column_name)

    new_columns = [_join(_remove_empty(column)) for column in df.columns.values]
    df.columns = new_columns

NOTE if you are using python 3.x:

request.FILES is a multivalue dictionary like object that keeps the files uploaded through an upload file button. Say in your html code the name of the button (type="file") is "myfile" so "myfile" will be the key in this dictionary. If you uploaded one file, then the value for this key will be only one and if you uploaded multiple files, then you will have multiple values for that specific key. If you use request.FILES['myfile'] you will get the first or last value (I cannot say for sure). This is fine if you only uploaded one file, but if you want to get all files you should do this:

list=[] #myfile is the key of a multi value dictionary, values are the uploaded files
for f in request.FILES.getlist('myfile'): #myfile is the name of your html file button
    filename = f.name
    list.append(filename)

of course one can squeeze the whole thing in one line, but this is easy to understand

Yes, you can write virtual "functions" in Java.

Steps to get sources of a jar file as a zip :

1. Download JD-GUI from http://java-decompiler.github.io/ and save it at any location on your system.

2. Drag and drop the jar or open .jar file for which you want the sources on the JD.

3. Java Decompiler will open with all the package structure in a tree format.

4. Click on File menu and select save jar sources. It will save the sources as a zip with the same name as the jar.

Example:-

We can use Eclipse IDE for Java EE Developers as well for update/extract code if require.

From eclipse chose Import Jar and then select jar which you need. Follow instruction as per image below

Not sure if your teacher allows you to use filters but...

filter(lambda x: x.isalpha(), "a1a2a3s3d4f5fg6h")

returns-

'aaasdffgh'

Much more efficient than looping...

Example:

for i in range(10):
  a.replace(str(i),'')

Interesting discussion. I was asking myself this question too. The main difference between fluid and fixed is simply that the fixed layout has a fixed width in terms of the whole layout of the website (viewport). If you have a 960px width viewport each colum has a fixed width which will never change.

The fluid layout behaves different. Imagine you have set the width of your main layout to 100% width. Now each column will only be calculated to it's relative size (i.e. 25%) and streches as the browser will be resized. So based on your layout purpose you can select how your layout behaves.

Here is a good article about fluid vs. flex.

After opening a file using vi

1) You can press Shift + g to go the end of the file

and

2) Press g twice to go to the beginning of the file

NOTE : - g is case-sensitive (Thanks to @Ben for pointing it out)

=== #---case equality

== #--- generic equality

both works similar but "===" even do case statements

"test" == "test"  #=> true
"test" === "test" #=> true

here the difference

String === "test"   #=> true
String == "test"  #=> false

I'll jump in with the notorious "Do you really want to do that" answer.

It seems like your focus is on playing with Java and seeing what it can do. However, if you want to actually develop a web app, you should be aware that, although Java is used in web applications (and in serious ones), there are other technology options which might be more adequate.

Personally, I like (and use) Java for powerful, portable backend services on a server. I've never tried building websites with it, because it never seemed the most obvious ting to do. After growing tired of PHP (which I have been using for years), I lately fell in love with Django, a Python-based web framework.

The Ruby on Rails people have a number of very funny videos on youtube comparing different web technologies to RoR. Of course, these are obviously exaggerated and maybe slightly biased, but I'd say there's more than one grain of truth in each of them. The one about Java is here. ;-)

An index is just a data structure that makes the searching faster for a specific column in a database. This structure is usually a b-tree or a hash table but it can be any other logic structure.

First of all, before providing an answer I would like to be upfront about the fact that by trusting headers you are opening the door to security vulnerabilities such as phishing. So for redirection purposes, don't use values from headers without first validating the URL is authorized.

Then, your operating system hostname might not necessarily match the DNS one. In fact, one IP might have more than one DNS name. So for HTTP purposes there is no guarantee that the hostname assigned to your machine in your operating system configuration is useable.

The best choice I can think of is to obtain your HTTP listener public IP and resolve its name via DNS. See the dns.reverse method for more info. But then, again, note that an IP might have multiple names associated with it.

This is similar to what has been posted, but it's clean, fast, and easy to read.

def fib(n):
# start with first two fib numbers
fib_list = [0, 1]
i = 0
# Create loop to iterate through n numbers, assuming first two given
while i < n - 2:
    i += 1
    # append sum of last two numbers in list to list
    fib_list.append(fib_list[-2] + fib_list[-1])
return fib_list

The following works in Python 2.6, 2.7, and 3.2:

import os
import sys
buf_arg = 0
if sys.version_info[0] == 3:
    os.environ['PYTHONUNBUFFERED'] = '1'
    buf_arg = 1
sys.stdout = os.fdopen(sys.stdout.fileno(), 'a+', buf_arg)
sys.stderr = os.fdopen(sys.stderr.fileno(), 'a+', buf_arg)

Yes, each package must be defined in its own directory.

The source structure is defined in How to Write Go Code.

A package is a component that you can use in more than one program, that you can publish, import, get from an URL, etc. So it makes sense for it to have its own directory as much as a program can have a directory.

sep='\t' is often used for Tab-delimited file.

I use the following rake task to override the Rails drop_database method.

lib/database.rake

require 'active_record/connection_adapters/postgresql_adapter'
module ActiveRecord
  module ConnectionAdapters
    class PostgreSQLAdapter < AbstractAdapter
      def drop_database(name)
        raise "Nah, I won't drop the production database" if Rails.env.production?
        execute <<-SQL
          UPDATE pg_catalog.pg_database
          SET datallowconn=false WHERE datname='#{name}'
        SQL

        execute <<-SQL
          SELECT pg_terminate_backend(pg_stat_activity.pid)
          FROM pg_stat_activity
          WHERE pg_stat_activity.datname = '#{name}';
        SQL
        execute "DROP DATABASE IF EXISTS #{quote_table_name(name)}"
      end
    end
  end
end

Edit: This is for Postgresql 9.2+

static_cast, aside from manipulating pointers to classes, can also be used to perform conversions explicitly defined in classes, as well as to perform standard conversions between fundamental types:

double d = 3.14159265;
int    i = static_cast<int>(d);

Here you go this should give you the correct answers every time!

a = int(input("Enter the coefficients of a: "))
b = int(input("Enter the coefficients of b: "))
c = int(input("Enter the coefficients of c: "))

d = b**2-4*a*c # discriminant

if d < 0:
    print ("This equation has no real solution")
elif d == 0:
    x = (-b+math.sqrt(b**2-4*a*c))/2*a
    print ("This equation has one solutions: "), x
else:
    x1 = (-b+math.sqrt((b**2)-(4*(a*c))))/(2*a)
    x2 = (-b-math.sqrt((b**2)-(4*(a*c))))/(2*a)
    print ("This equation has two solutions: ", x1, " or", x2)

Swift 5:

1- Create a String extension to get attributedText

extension String {

    var underLined: NSAttributedString {
        NSMutableAttributedString(string: self, attributes: [.underlineStyle: NSUnderlineStyle.single.rawValue])
    }

}

2- Use it

On buttons:

button.setAttributedTitle(yourButtonTitle.underLined, for: .normal)

On Labels:

label.attributedText = yourLabelTitle.underLined

Or Stoyboard version

File sdCard = Environment.getExternalStorageDirectory();
File dir = new File (sdCard.getAbsolutePath() + "/dir1/dir2");
dir.mkdirs();
File file = new File(dir, "filename");

FileOutputStream f = new FileOutputStream(file);
...

The reason you are getting the the IOException is because you are not catching the IOException of your countLines method. You'll want to do something like this:

public static void main(String[] args) {
  int lines = 0;  

  // TODO - Need to get the filename to populate sFileName.  Could
  // come from the command line arguments.

   try {
       lines = LineCounter.countLines(sFileName);
    }
    catch(IOException ex){
        System.out.println (ex.toString());
        System.out.println("Could not find file " + sFileName);
    }

   if(lines > 0) {
     // Do rest of program.
   }
}

Below is a class which will accomplish the very basics of what you want to do when reading data from a MySQL database into a JTable in Java.

                    }

In the NetBeans IDE which you are using - you will need to add the MySQL JDBC Driver in Project Properties as I display here:

Otherwise the code will throw an SQLException stating that the driver cannot be found.

Now in my example, yourdb is the name of the database and animals is the name of the table that I am performing a query against.

Here is what will be output:

Parting note:

You stated that you were a novice and needed some help understanding some of the basic classes and concepts of Java. I will list a few here, but remember you can always browse the docs on Oracle's site.

• ArrayList
• Vector
• Try-with-resources statement

You must use an integer value for the CURLOPT_SSLVERSION value, not a string as listed above

Try this:

curl_setopt ($setuploginurl, CURLOPT_SSLVERSION, 6); //Integer NOT string TLS v1.2

http://php.net/manual/en/function.curl-setopt.php

value should be an integer for the following values of the option parameter: CURLOPT_SSLVERSION

One of

CURL_SSLVERSION_DEFAULT (0)
CURL_SSLVERSION_TLSv1 (1)
CURL_SSLVERSION_SSLv2 (2)
CURL_SSLVERSION_SSLv3 (3)
CURL_SSLVERSION_TLSv1_0 (4)
CURL_SSLVERSION_TLSv1_1 (5)
CURL_SSLVERSION_TLSv1_2 (6).

Use the following sed command for removing the null characters in a file.

sed -i 's/\x0//g' null.txt

this solution edits the file in place, important if the file is still being used. passing -i'ext' creates a backup of the original file with 'ext' suffix added.

For windows-

1. In the Control Panel, choose Add or Remove Programs or Uninstall a program, and then select Python 3.6 (Anaconda) or your version of Python.
2. Use Windows Explorer to delete the envs and pkgs folders prior to Running the uninstall in the root of your installation.

Inside the component put the input box in the following way.

<input className="class-name"
              type= "text"
              id="id-123"
              value={ this.state.value || "" }
              name="field-name"
              placeholder="Enter Name"
              />

You want

String[] strarray = strlist.toArray(new String[0]);

See here for the documentation and note that you can also call this method in such a way that it populates the passed array, rather than just using it to work out what type to return. Also note that maybe when you print your array you'd prefer

System.out.println(Arrays.toString(strarray));

since that will print the actual elements.

For me "Restarting Mac System" got worked

var array = [[1, "grape", 42], [2, "fruit", 9]];

array.sort(function(a, b)
{
    // a and b will here be two objects from the array
    // thus a[1] and b[1] will equal the names

    // if they are equal, return 0 (no sorting)
    if (a[1] == b[1]) { return 0; }
    if (a[1] > b[1])
    {
        // if a should come after b, return 1
        return 1;
    }
    else
    {
        // if b should come after a, return -1
        return -1;
    }
});

The sort function takes an additional argument, a function that takes two arguments. This function should return -1, 0 or 1 depending on which of the two arguments should come first in the sorting. More info.

I also fixed a syntax error in your multidimensional array.

You could use char(39)

insert into my_table values('hi, my name'+char(39)+'s tim.')

Or in this case:

Replace(@strip,char(39),'')

You can also use file_put_contents():

file_put_contents('ids.txt', implode("\n", $gemList) . "\n", FILE_APPEND);

To post files as from byte arrays:

private static string UploadFilesToRemoteUrl(string url, IList<byte[]> files, NameValueCollection nvc) {

        string boundary = "----------------------------" + DateTime.Now.Ticks.ToString("x");

        var request = (HttpWebRequest) WebRequest.Create(url);
        request.ContentType = "multipart/form-data; boundary=" + boundary;
        request.Method = "POST";
        request.KeepAlive = true;
        var postQueue = new ByteArrayCustomQueue();

        var formdataTemplate = "\r\n--" + boundary + "\r\nContent-Disposition: form-data; name=\"{0}\";\r\n\r\n{1}";

        foreach (string key in nvc.Keys) {
            var formitem = string.Format(formdataTemplate, key, nvc[key]);
            var formitembytes = Encoding.UTF8.GetBytes(formitem);
            postQueue.Write(formitembytes);
        }

        var headerTemplate = "\r\n--" + boundary + "\r\n" +
            "Content-Disposition: form-data; name=\"{0}\"; filename=\"{1}\"\r\n" + 
            "Content-Type: application/zip\r\n\r\n";

        var i = 0;
        foreach (var file in files) {
            var header = string.Format(headerTemplate, "file" + i, "file" + i + ".zip");
            var headerbytes = Encoding.UTF8.GetBytes(header);
            postQueue.Write(headerbytes);
            postQueue.Write(file);
            i++;
        }

        postQueue.Write(Encoding.UTF8.GetBytes("\r\n--" + boundary + "--"));

        request.ContentLength = postQueue.Length;

        using (var requestStream = request.GetRequestStream()) {
            postQueue.CopyToStream(requestStream);
            requestStream.Close();
        }

        var webResponse2 = request.GetResponse();

        using (var stream2 = webResponse2.GetResponseStream())
        using (var reader2 = new StreamReader(stream2)) {

            var res =  reader2.ReadToEnd();
            webResponse2.Close();
            return res;
        }
    }

public class ByteArrayCustomQueue {

    private LinkedList<byte[]> arrays = new LinkedList<byte[]>();

    /// <summary>
    /// Writes the specified data.

In order to generate key hash you need to follow some easy steps.

1) Download Openssl from: here.

2) Make a openssl folder in C drive

3) Extract Zip files into this openssl folder created in C Drive.

4) Copy the File debug.keystore from .android folder in my case (C:\Users\SYSTEM.android) and paste into JDK bin Folder in my case (C:\Program Files\Java\jdk1.6.0_05\bin)

5) Open command prompt and give the path of JDK Bin folder in my case (C:\Program Files\Java\jdk1.6.0_05\bin).

6) Copy the following code and hit enter

keytool -exportcert -alias androiddebugkey -keystore debug.keystore > c:\openssl\bin\debug.txt

7) Now you need to enter password, Password = android.

8) If you see in openssl Bin folder, you will get a file with the name of debug.txt

9) Now either you can restart command prompt or work with existing command prompt

10) get back to C drive and give the path of openssl Bin folder

11) copy the following code and paste

openssl sha1 -binary debug.txt > debug_sha.txt

12) you will get debug_sha.txt in openssl bin folder

13) Again copy following code and paste

openssl base64 -in debug_sha.txt > debug_base64.txt

14) you will get debug_base64.txt in openssl bin folder

15) open debug_base64.txt file Here is your Key hash.

                             $join->on('rooms.id', '=', 'bookings.room_type_id');
                             $join->on('arrival','>=',DB::raw("'2012-05-01'"));
                             $join->on('arrival','<=',DB::raw("'2012-05-10'"));
                             $join->on('departure','>=',DB::raw("'2012-05-01'"));
                             $join->on('departure','<=',DB::raw("'2012-05-10'"));
                         })
                     ->where('bookings.room_type_id', '=', NULL)
                     ->get();

Not quite sure if the between clause can be added to the join in laravel.

Notes:

• DB::raw() instructs Laravel not to put back quotes.
• By passing a closure to join methods you can add more join conditions to it, on() will add AND condition and orOn() will add OR condition.

try this  **USE ORDER BY** :

   public class Employee
    {
        public string Id { get; set; }
        public string Name { get; set; }
    }

 private static IList<Employee> GetItems()
        {
            List<Employee> lst = new List<Employee>();

            lst.Add(new Employee { Id = "1", Name = "Emp1" });
            lst.Add(new Employee { Id = "2", Name = "Emp2" });
            lst.Add(new Employee { Id = "7", Name = "Emp7" });
            lst.Add(new Employee { Id = "4", Name = "Emp4" });
            lst.Add(new Employee { Id = "5", Name = "Emp5" });
            lst.Add(new Employee { Id = "6", Name = "Emp6" });
            lst.Add(new Employee { Id = "3", Name = "Emp3" });

            return lst;
        }

**var lst = GetItems().AsEnumerable();

            var orderedLst = lst.OrderBy(t => t.Id).ToList();

            orderedLst.ForEach(emp => Console.WriteLine("Id - {0} Name -{1}", emp.Id, emp.Name));**

Use

// aspect-type.js
class AspectType {

}

export default AspectType;

Then to import it

// some-other-file.js
import AspectType from './aspect-type';

Here's my solution, which has a few improvements over other suggestions:

String.prototype.truncate = function(){
    var re = this.match(/^.{0,25}[\S]*/);
    var l = re[0].length;
    var re = re[0].replace(/\s$/,'');
    if(l < this.length)
        re = re + "&hellip;";
    return re;
}

// "This is a short string".truncate();
"This is a short string"

// "Thisstringismuchlongerthan25characters".truncate();
"Thisstringismuchlongerthan25characters"

// "This string is much longer than 25 characters and has spaces".truncate();
"This string is much longer&hellip;"

It:

• Truncates on the first space after 25 characters
• Extends the JavaScript String object, so it can be used on (and chained to) any string.
• Will trim the string if truncation results in a trailing space;
• Will add the unicode hellip entity (ellipsis) if the truncated string is longer than 25 characters

Run the following commands from git CLI:

# move to the wanted commit
git reset --hard <commit-hash> 

# update remote
git push --force origin <branch-name> 

map(lambda s: s.strip(), mylist) would be a little better than explicitly looping. Or for the whole thing at once: map(lambda s:s.strip(), string.split(','))

You need Pexpect to get the best of both worlds (expect and ssh wrappers).

Solution

To see the option for USB debugging mode in Nexus 4 or Android 4.2 or higher OS, do the following:

• Open up your device’s “Settings”. This can be done by pressing the Menu button while on your home screen and tapping “System settings”
• Now scroll to the bottom and tap “About phone” or “About tablet”.
• At the “About” screen, scroll to the bottom and tap on “Build number” seven times.
  • Make sure you tap seven times. If you see a “Not need, you are already a developer!” message pop up, then you know you have done it correctly.

Done! By tapping on “Build number” seven times, you have unlocked USB debugging mode on Android 4.2 and higher. You can now enable/disable it whenever you desire by going to “Settings” -> “Developer Options” -> “Debugging” ->” USB debugging”.

CONCLUSION

That was easy. The best part is you only have to do the tap-build-number-seven-times once. After you do it once, USB debugging has been unlocked and you can enable or disable at your leisure. Please restart after done these steps.

It worked using PSCP. Instructions:

1. Download PSCP.EXE from Putty download page
2. Open command prompt and type set PATH=<path to the pscp.exe file>
3. In command prompt point to the location of the pscp.exe using cd command
4. Type pscp

5. use the following command to copy file form remote server to the local system

   pscp [options] [user@]host:source target
   

So to copy the file /etc/hosts from the server example.com as user fred to the file c:\temp\example-hosts.txt, you would type:

pscp [email protected]:/etc/hosts c:\temp\example-hosts.txt

JAVA HOME is used for setting up the environment variable for JAVA. It means that you are providing a path for compiling a JAVA program and also running the same. So, if you do not set the JAVA HOME( PATH ) and try to run a java or any dependent program in the command prompt.

You will deal with an error as javac : not recognized as internal or external command. Now to set this, Just open your Java jdk then open bin folder then copy the PATH of that bin folder.

Now, go to My computer right click on it----> select properties-----> select Advanced system settings----->Click on Environment Variables------>select New----->give a name in the text box Variable Name and then paste the path in Value.

That's All!!

If you bracket the @ you can use it directly

declare @TEMP table (ID int, Name varchar(max))
insert into @temp values (1,'one'), (2,'two')

SELECT * FROM @TEMP 
WHERE [@TEMP].[ID] = 1
