This is due to the series df[cat] containing elements that have varying data types e.g.(strings and/or floats). This could be due to the way the data is read, i.e. numbers are read as float and text as strings or the datatype was float and changed after the fillna operation.

In other words

pandas data type 'Object' indicates mixed types rather than str type

so using the following line:

df[cat] = le.fit_transform(df[cat].astype(str))

should help

1. The syntax for specifying url is {% url namespace:url_name %}. So, check if you have added the app_name in urls.py.
2. In my case, I had misspelled the url_name. The urls.py had the following content path('<int:question_id>/', views.detail, name='question_detail') whereas the index.html file had the following entry <li><a href="{% url 'polls:detail' question.id %}">{{ question.question_text }}</a></li>. Notice the incorrect name.

I found all answers above incomplete somehow, Below are exact steps to get it working.

1. We use npm in order to install the package. For this open the Console and go to your Laravel application directory. Enter the following:

   npm install font-awesome --save-dev

2. Now we have to copy the needed files to the public/css and public/fonts directory. In order to do this open the webpack.mix.js file and add the following:

   mix.copy('node_modules/font-awesome/css/font-awesome.min.css', 'public/css'); mix.copy('node_modules/font-awesome/fonts/*', 'public/fonts');

3. Run the following command in order to execute Laravel Mix:

   npm run dev

4. Add the stylesheet for the Font Awesome in your applications layout file (resources/views/layouts/app.blade.phpapp.blade.php):

   <link href="{{ asset('css/font-awesome.min.css') }}" rel="stylesheet" />

5. Use font awesome icons in templates like

   <i class="fa fa-address-book" aria-hidden="true"></i>

I hope it helps!

I don't remember the specific source, but I am using:

    /* Number of Cards by Row based on Viewport */
    @media (min-width: 576px) {
        .card-deck .card {
            min-width: 50.1%; /* 1 Column */
            margin-bottom: 12px;

    }
    @media (min-width: 768px) {
        .card-deck .card {

        }
    }
    @media (min-width: 1200px) {
        .card-deck .card {

You may want to tinker with the specific values to fit your needs.

After updating my Android SDK I stumbled upon this very problem and I tried many ways without success. What was most irritating to me when searching for a fix, were the lots of answers suggesting to change the CompileSdkVersion to a certain number while obviously this number changes with time, so here's what I did instead.

I created a new project and ran it on the emulator to make sure it's working, then checked its "\android\app\build.gradle" file and copied the numeric value of CompileSdkVersion and pasted into the same file in my other project that could not be built properly anymore. Now my problem's gone. Hope that helps.

UPDATE: In Bootstrap 4, flexbox is now default, and each card-deck row will contain 3 cards. The cards will fill to full height.

http://www.codeply.com/go/x91w5Cl6ip

The Bootstrap 4 alpha card-columns uses CSS3 columns which don't really support equal heights (except column-fill which is only suppored in Firefox).

If you instead enable Bootstrap 4 flexbox mode, you could instead use the card-deck and a little CSS to equalize the height and wrap every 3 columns.

@media (min-width:34em) {
    .card-deck > .card
    {
        width: 29%;
        flex-wrap: wrap;
        flex: initial; 
    }
}

Lists of bytes are subscriptable (at least in Python 3.6). This way you can retrieve the decimal value of each byte individually.

>>> intlist = [64, 4, 26, 163, 255]
>>> bytelist = bytes(intlist)       # b'@x04\x1a\xa3\xff'

>>> for b in bytelist:
...    print(b)                     # 64  4  26  163  255

>>> [b for b in bytelist]           # [64, 4, 26, 163, 255]

>>> bytelist[2]                     # 26 

you should change your compiledsdkversion and targetversion to 23 in the build gradle file specific to the app.Make sure you installed sdk 23, version 6.0 before this.You can watch this vid for more help.https://www.youtube.com/watch?v=pw4jKsOU7go

First off, it might not be good to just go by recall alone. You can simply achieve a recall of 100% by classifying everything as the positive class. I usually suggest using AUC for selecting parameters, and then finding a threshold for the operating point (say a given precision level) that you are interested in.

For how class_weight works: It penalizes mistakes in samples of class[i] with class_weight[i] instead of 1. So higher class-weight means you want to put more emphasis on a class. From what you say it seems class 0 is 19 times more frequent than class 1. So you should increase the class_weight of class 1 relative to class 0, say {0:.1, 1:.9}. If the class_weight doesn't sum to 1, it will basically change the regularization parameter.

For how class_weight="auto" works, you can have a look at this discussion. In the dev version you can use class_weight="balanced", which is easier to understand: it basically means replicating the smaller class until you have as many samples as in the larger one, but in an implicit way.

From the 18.03 docs:

I want to connect from a container to a service on the host

The host has a changing IP address (or none if you have no network access). From 18.03 onwards our recommendation is to connect to the special DNS name host.docker.internal, which resolves to the internal IP address used by the host.

The gateway is also reachable as gateway.docker.internal.

EXAMPLE: Here's what I use for my MySQL connection string inside my container to access the MySQL instance on my host:

mysql://host.docker.internal:3306/my_awesome_database

I used placeholders so just follow along, as you might want to still keep the inheritance from the original style.

Before

    android:background="?attr/colorPrimary"
    android:elevation="4dp"
    android:theme="@style/{{originalBaseStyle}}"
    app:popupTheme="@style/ThemeOverlay.AppCompat.Light"/>

This has happened to me after I "updated" into 5.0 SDK and wanted to create a new application with support library

In both Projects (project.properties file) in the one you want to use support library and the support library itself it has to be set the same target

e.g. for my case it worked

1. In project android-support-v7-appcompat Change project.properties into target=android-21
2. Cleanandroid-support-v7-appcompat In my project (where I desire support library)
3. In my project, Change project.properties into target=android-21 and android.library.reference.1=../android-support-v7-appcompat (or add support library in project properties)
4. Clean the project

Just select target api level to 21 for compiling, click Apply -> click OK, clean and build project and run it.

To create icon you can use Glyphicon in Bootstrap:

<a href="#" class="btn btn-info btn-sm">
    <span class="glyphicon glyphicon-menu-hamburger"></span>
</a>

And then control size of icon in css:

.glyphicon-menu-hamburger {
  font-size: npx;
}

use - !important - to override default black

.fa-heart:hover{_x000D_
   color:red !important;_x000D_
}_x000D_
.fa-heart-o:hover{_x000D_
   color:red !important;_x000D_
}

<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/font-awesome/4.7.0/css/font-awesome.min.css">_x000D_
_x000D_
<i class="fa fa-heart fa-2x"></i>_x000D_
<i class="fa fa-heart-o fa-2x"></i>

I've the same problem right now. check if you fix fetch in lazy with a @jsonIQgnore

@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name="teachers")
@JsonIgnoreProperties("course")
Teacher teach;

Just delete the "(fetch=...)" or the annotation "@jsonIgnore" and it will work

@ManyToOne
@JoinColumn(name="teachers")
@JsonIgnoreProperties("course")
Teacher teach;

The syntax is :

.nav navbar-nav .navbar-right > li > a {
   color: blue;
}

The placeholder image you're including has a height of 50px. It is wrapped in an anchor (.navbar-brand) with a padding-top of 15px and a height of 50px. That's why the placeholder logo flows out of the bar. Try including a smaller image or play with the anchor's padding by assigning a class or an id to it wich you can reference in your css.

EDIT Or remove the static height: 50px from .navbar-brand. Your navbar will then take the height of its highest child.

h3 in bootstrap by default has a padding-top of 20px. Again, it is wrapped with that padding-top: 15px anchor. That's why it's not vertically centered like you want it. You could give the h3 a class or and id that resets the margin-top. And the same you could do with the padding of the anchor.

Here's something to play with: http://jsbin.com/jelec/1/edit?html,output

The reason is that when you use lazy load, the session is closed.

There are two solutions.

1. Don't use lazy load.

   Set lazy=false in XML or Set @OneToMany(fetch = FetchType.EAGER) In annotation.

2. Use lazy load.

   Set lazy=true in XML or Set @OneToMany(fetch = FetchType.LAZY) In annotation.

   and add OpenSessionInViewFilter filter in your web.xml

Detail See my post.

https://stackoverflow.com/a/27286187/1808417

What about inv?

e.g.: my_inverse_array = inv(my_array)

In bootstrap 4 use:

<ul class="nav navbar-nav ml-auto">

This will push the navbar to the right. Use mr-auto to push it to the left, this is the default behaviour.

use flexbox as you can use it at your disposal. The solution offered by bootstrap 4 still hunting overlap content in responsive layout, e.g: it will break in mobile view, i come across the most neat trick is to use flexbox solution demo shown at here:(https://philipwalton.github.io/solved-by-flexbox/demos/sticky-footer/) this way we do not have to deal with fixed height issue which is an obsolete solution by now...this solution works for bootstrap 3 and 4 whichever you using.

<body class="Site">
  <header>…</header>
  <main class="Site-content">…</main>
  <footer>…</footer>
</body>

.Site {
  display: flex;
  min-height: 100vh;
  flex-direction: column;
}

.Site-content {
  flex: 1;
}

The class is .navbar-default. You need to create a class on your custom css .navbar-default.And follow the css code. Also if you don’t want box-shadow on your menu, you can put on the same class.

 .navbar-default {
      background-color:transparent !important;
      border-color:transparent;
      background-image:none;
      box-shadow:none;  
 }

To change font navbar color, the class is to change – .navbar-default .navbar-nav>li>a see the code bellow:

  .navbar-default .navbar-nav>li>a {
     font-size:20px; 
     color:#fff; 
 }

ref : http://twitterbootstrap.org/bootstrap-navbar-background-color-transparent/

There are just two minor things here.

The first is in the following carousel indicator list items:

<li data-target="carousel" data-slide-to="0"></li>

You need to pass the data-target attribute a selector which means the ID must be prefixed with #. So change them to the following:

<li data-target="#carousel" data-slide-to="0"></li>

Secondly, you need to give the carousel a starting point so both the carousel indicator items and the carousel inner items must have one active class. Like this:

<ol class="carousel-indicators">
    <li data-target="#carousel" data-slide-to="0" class="active"></li>
    <!-- Other Items -->
</ol>
<div class="carousel-inner">
    <div class="item active">
        <img src="https://picsum.photos/1500/600?image=1" alt="Slide 1" />
    </div>
    <!-- Other Items -->
</div>

Working Demo in Fiddle

NORMSINV (mentioned in a comment) is the inverse of the CDF of the standard normal distribution. Using scipy, you can compute this with the ppf method of the scipy.stats.norm object. The acronym ppf stands for percent point function, which is another name for the quantile function.

In [20]: from scipy.stats import norm

In [21]: norm.ppf(0.95)
Out[21]: 1.6448536269514722

Check that it is the inverse of the CDF:

In [34]: norm.cdf(norm.ppf(0.95))
Out[34]: 0.94999999999999996

By default, norm.ppf uses mean=0 and stddev=1, which is the "standard" normal distribution. You can use a different mean and standard deviation by specifying the loc and scale arguments, respectively.

In [35]: norm.ppf(0.95, loc=10, scale=2)
Out[35]: 13.289707253902945

If you look at the source code for scipy.stats.norm, you'll find that the ppf method ultimately calls scipy.special.ndtri. So to compute the inverse of the CDF of the standard normal distribution, you could use that function directly:

In [43]: from scipy.special import ndtri

In [44]: ndtri(0.95)
Out[44]: 1.6448536269514722

I would like to add another Bootstrap 4 solution. One that worked for me.

The CSS "Order" property, combined with a media query, can be used to re-order columns when they get stacked in smaller screens.

Something like this:

@media only screen and (max-width: 768px) {
    #first {
        order: 2;
    }
    #second {
        order: 4;
    }
    #third {
        order: 1;
    }
    #fourth {
        order: 3;
    }
}

CodePen Link: https://codepen.io/preston206/pen/EwrXqm

Adjust the screen size and you'll see the columns get stacked in a different order.

I'll tie this in with the original poster's question. With CSS, the navbar, sidebar, and content can be targeted and then order properties applied within a media query.

I found that you don't necessarily need the text vertically centred, it also looks good near the bottom of the row, it's only when it's at the top (or above centre?) that it looks wrong. So I went with this to push the links to the bottom of the row:

.navbar-brand {
    min-height: 80px;
}

@media (min-width: 768px) {
    #navbar-collapse {
        position: absolute;
        bottom: 0px;
        left: 250px;
    }
}

My brand image is SVG and I used height: 50px; width: auto which makes it about 216px wide. It spilled out of its container vertically so I added the min-height: 80px; to make room for it plus bootstrap's 15px margins. Then I tweaked the navbar-collapse's left setting until it looked right.

with this globals variables idea, I saved MainActivity instance in onCreate(); Android global variable

public class ApplicationController extends Application {

    public static MainActivity this_MainActivity;
}

and Open dialog like this. it worked.

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    // Global Var
    globals = (ApplicationController) this.getApplication();
    globals.this_MainActivity = this;
}

and in a thread, I open dialog like this.

AlertDialog.Builder alert = new AlertDialog.Builder(globals.this_MainActivity);

1. Open MainActivity
2. Start a thread.
3. Open dialog from thread -> work.
4. Click "Back button" ( onCreate will be called and remove first MainActivity)
5. New MainActivity will start. ( and save it's instance to globals )
6. Open dialog from first thread --> it will open and work.

: )

Proper way to do it is to change the width on the online customizer here:

http://getbootstrap.com/customize/

download the recompiled source, overwrite the existing bootstrap dist dir, and reload (mind the browser cache!!!)

All your changes will be retained in the .json configuration file

To apply again the all the changes just upload the json file and you are ready to go

If you use android studio, this might be useful for you.

I had a similar problem and i solved it by changing the skd path from the default C:\Program Files (x86)\Android\android-studio\sdk to C:\Program Files (x86)\Android\android-sdk .

It seems the problem came from the compiler version (gradle sets it automatically to the highest one available in the sdk folder) which doesn't support this theme, and since android studio had only the api 7 in its sdk folder, it gave me this error.

I had the same issue I remove the following script and it worked for me.

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.2/jquery.min.js"></script>

You can use localStorage ( http://www.w3schools.com/html/html5_webstorage.asp ) to save values before refreshing the page.

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'

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

Simply add this to your css :-

.navbar-inner {
    background:transparent;
}

This is how I did it. This makes the images in the slideshow take up the full screen if it´s aspect ratio allows it, othervice it scales down.

.carousel {
    height: 100vh;
    width: 100%;
    overflow:hidden;
}
.carousel .carousel-inner {
    height:100%;    
}

To allways get a full screen slideshow, no matter screen aspect ratio, you can also use object-fit: (doesn´t work in IE or Edge)

.carousel .carousel-inner img {
    display:block;
    object-fit: cover;
}

Another way of getting the results

SELECT * from table WHERE SUBSTRING(tester, 1, 8)  <> 'username' or tester is null

According to documentation you can use the reverse argument.

filter:orderBy(array, expression[, reverse]);

Change your filter to:

orderBy: 'created_at':true

if you use EntityRepository then use saveAndFlush instead of save

Building on @general03's answer, you can use Android's built-in style to customize the dialog quickly. You can find the dialog themes under android.R.style.Theme_DeviceDefault_Dialogxxx.

For example:

builder = new AlertDialog.Builder(this, android.R.style.Theme_DeviceDefault_Dialog_MinWidth);
builder = new AlertDialog.Builder(this, android.R.style.Theme_DeviceDefault_Dialog_NoActionBar);
builder = new AlertDialog.Builder(this, android.R.style.Theme_DeviceDefault_DialogWhenLarge);

You should use partial views. I use the following approach:

Use a view model so you're not passing your domain models to your views:

public class EditPersonViewModel
{
    public int Id { get; set; }   // this is only used to retrieve record from Db
    public string Name { get; set; }
    public string Age { get; set; }
}

In your PersonController:

[HttpGet] // this action result returns the partial containing the modal
public ActionResult EditPerson(int id)
{  
    var viewModel = new EditPersonViewModel();
    viewModel.Id = id;
    return PartialView("_EditPersonPartial", viewModel);
}

[HttpPost] // this action takes the viewModel from the modal
public ActionResult EditPerson(EditPersonViewModel viewModel)
{
    if (ModelState.IsValid)
    {
        var toUpdate = personRepo.Find(viewModel.Id);
        toUpdate.Name = viewModel.Name;
        toUpdate.Age = viewModel.Age;
        personRepo.InsertOrUpdate(toUpdate);
        personRepo.Save();
        return View("Index");
    }
}

Next create a partial view called _EditPersonPartial. This contains the modal header, body and footer. It also contains the Ajax form. It's strongly typed and takes in our view model.

@model Namespace.ViewModels.EditPersonViewModel
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>
    <h3 id="myModalLabel">Edit group member</h3>
</div>
<div>
@using (Ajax.BeginForm("EditPerson", "Person", FormMethod.Post,
                    new AjaxOptions
                    {
                        InsertionMode = InsertionMode.Replace,
                        HttpMethod = "POST",
                        UpdateTargetId = "list-of-people"
                    }))
{
    @Html.ValidationSummary()
    @Html.AntiForgeryToken()
    <div class="modal-body">
        @Html.Bootstrap().ControlGroup().TextBoxFor(x => x.Name)
        @Html.Bootstrap().ControlGroup().TextBoxFor(x => x.Age)
    </div>
    <div class="modal-footer">
        <button class="btn btn-inverse" type="submit">Save</button>
    </div>
}

Now somewhere in your application, say another partial _peoplePartial.cshtml etc:

<div>
   @foreach(var person in Model.People)
    {
        <button class="btn btn-primary edit-person" data-id="@person.PersonId">Edit</button>
    }
</div>
// this is the modal definition
<div class="modal hide fade in" id="edit-person">
    <div id="edit-person-container"></div>
</div>

    <script type="text/javascript">
    $(document).ready(function () {
        $('.edit-person').click(function () {
            var url = "/Person/EditPerson"; // the url to the controller
            var id = $(this).attr('data-id'); // the id that's given to each button in the list
            $.get(url + '/' + id, function (data) {
                $('#edit-person-container').html(data);
                $('#edit-person').modal('show');
            });
        });
     });
   </script>

You have to add the selector parameter, otherwise the event is directly bound instead of delegated, which only works if the element already exists (so it doesn't work for dynamically loaded content).

See http://api.jquery.com/on/#direct-and-delegated-events

Change your code to

$(document.body).on('click', '.update' ,function(){

The jQuery set receives the event then delegates it to elements matching the selector given as argument. This means that contrary to when using live, the jQuery set elements must exist when you execute the code.

As this answers receives a lot of attention, here are two supplementary advises :

1) When it's possible, try to bind the event listener to the most precise element, to avoid useless event handling.

That is, if you're adding an element of class b to an existing element of id a, then don't use

$(document.body).on('click', '#a .b', function(){

but use

$('#a').on('click', '.b', function(){

2) Be careful, when you add an element with an id, to ensure you're not adding it twice. Not only is it "illegal" in HTML to have two elements with the same id but it breaks a lot of things. For example a selector "#c" would retrieve only one element with this id.

What onetrickpony posted is okay, but if you want to have a more general solution, you can just use the code below.

Instead of selecting just the id of the anchor, you can make it bit more standard-like and just selecting the attribute name of the <a>-Tag. This will save you from writing an extra id tag. Just add the smoothscroll class to the navbar element.

What changed

1) $('#nav ul li a[href^="#"]') to $('#nav.smoothscroll ul li a[href^="#"]')

2) $(this.hash) to $('a[name="' + this.hash.replace('#', '') + '"]')

Final Code

/* Enable smooth scrolling on all links with anchors */
$('#nav.smoothscroll ul li a[href^="#"]').on('click', function(e) {

  // prevent default anchor click behavior
  e.preventDefault();

  // store hash
  var hash = this.hash;

  // animate
  $('html, body').animate({
    scrollTop: $('a[name="' + this.hash.replace('#', '') + '"]').offset().top
  }, 300, function(){

    // when done, add hash to url
    // (default click behaviour)
    window.location.hash = hash;

  });
});

I don't believe that the framework itself has this class. Maybe a third-party library...

But why not create a Period value-object class to handle this complexity? That way you can ensure other constraints, like validating start vs end datetimes. Something like:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace Whatever.Domain.Timing {
    public class Period {
        public DateTime StartDateTime {get; private set;}
        public DateTime EndDateTime {get; private set;}

        public Period(DateTime StartDateTime, DateTime EndDateTime) {
            if (StartDateTime > EndDateTime)
                throw new InvalidPeriodException("End DateTime Must Be Greater Than Start DateTime!");
            this.StartDateTime = StartDateTime;
            this.EndDateTime = EndDateTime;
        }


        public bool Overlaps(Period anotherPeriod){
            return (this.StartDateTime < anotherPeriod.EndDateTime && anotherPeriod.StartDateTime < this.EndDateTime)
        }

        public TimeSpan GetDuration(){
            return EndDateTime - StartDateTime;
        }

    }

    public class InvalidPeriodException : Exception {
        public InvalidPeriodException(string Message) : base(Message) { }    
    }
}

That way you will be able to individually compare each period...

If you want a list of lists:

>>> [list(t) for t in zip(*l)]
[[1, 3, 8], [2, 4, 9]]

If a list of tuples is OK:

>>> zip(*l)
[(1, 3, 8), (2, 4, 9)]

This is all a bit roundabout..

I've used the glyphs like this

  </div>
        <div class="span2">
            <span class="glyphicons thumbs_up"><i class="green"></i></span>
        </div>
        <div class="span2">
            <span class="glyphicons thumbs_down"><i class="red"></i></span>
        </div>

and to affect the color, i included a bit of css at the head like this

<style>
        i.green:before {
            color: green;
        }
        i.red:before {
            color: red;
        }
    </style>

Voila, green and red thumbs.

My bible for JPA work is the Java Persistence wikibook. It has a section on unidirectional OneToMany which explains how to do this with a @JoinColumn annotation. In your case, i think you would want:

@OneToMany
@JoinColumn(name="TXTHEAD_CODE")
private Set<Text> text;

I've used a Set rather than a List, because the data itself is not ordered.

The above is using a defaulted referencedColumnName, unlike the example in the wikibook. If that doesn't work, try an explicit one:

@OneToMany
@JoinColumn(name="TXTHEAD_CODE", referencedColumnName="DATREG_META_CODE")
private Set<Text> text;

Note that if you care about speed and do not need to worry about singularities, solve() should be preferred to ginv() because it is much faster, as you can check:

require(MASS)
mat <- matrix(rnorm(1e6),nrow=1e3,ncol=1e3)

t0 <- proc.time()
inv0 <- ginv(mat)
proc.time() - t0 

t1 <- proc.time()
inv1 <- solve(mat)
proc.time() - t1 

Python dictionaries have a key and a value, what you are asking for is what key(s) point to a given value.

You can only do this in a loop:

[k for (k, v) in i.iteritems() if v == 0]

Note that there can be more than one key per value in a dict; {'a': 0, 'b': 0} is perfectly legal.

If you want ordering you either need to use a list or a OrderedDict instance instead:

items = ['a', 'b', 'c']
items.index('a') # gives 0
items[0]         # gives 'a'

I actual ran into the same requirement. I simply used CSS override like this

.navbar .btn-toolbar { margin-top: 0; margin-bottom: 0 }

grep matches, grep -v does the inverse. If you need to "match A but not B" you usually use pipes:

grep "${PATT}" file | grep -v "${NOTPATT}"

As it was already mentioned in previous answers, your matrix cannot be inverted, because its determinant is 0. But if you still want to get inverse matrix, you can use np.linalg.pinv, which leverages SVD to approximate initial matrix.

Added: I found something that should do the trick right away, but the rest of the code below also offers an alternative.

Use the subplots_adjust() function to move the bottom of the subplot up:

fig.subplots_adjust(bottom=0.2) # <-- Change the 0.02 to work for your plot.

Then play with the offset in the legend bbox_to_anchor part of the legend command, to get the legend box where you want it. Some combination of setting the figsize and using the subplots_adjust(bottom=...) should produce a quality plot for you.

Alternative: I simply changed the line:

fig = plt.figure(1)

to:

fig = plt.figure(num=1, figsize=(13, 13), dpi=80, facecolor='w', edgecolor='k')

and changed

lgd = ax.legend(loc=9, bbox_to_anchor=(0.5,0))

to

lgd = ax.legend(loc=9, bbox_to_anchor=(0.5,-0.02))

and it shows up fine on my screen (a 24-inch CRT monitor).

Here figsize=(M,N) sets the figure window to be M inches by N inches. Just play with this until it looks right for you. Convert it to a more scalable image format and use GIMP to edit if necessary, or just crop with the LaTeX viewport option when including graphics.

You can pass a numpy array or matrix as an argument when initializing a sparse matrix. For a CSR matrix, for example, you can do the following.

>>> import numpy as np
>>> from scipy import sparse
>>> A = np.array([[1,2,0],[0,0,3],[1,0,4]])
>>> B = np.matrix([[1,2,0],[0,0,3],[1,0,4]])

>>> A
array([[1, 2, 0],
       [0, 0, 3],
       [1, 0, 4]])

>>> sA = sparse.csr_matrix(A)   # Here's the initialization of the sparse matrix.
>>> sB = sparse.csr_matrix(B)

>>> sA
<3x3 sparse matrix of type '<type 'numpy.int32'>'
        with 5 stored elements in Compressed Sparse Row format>

>>> print sA
  (0, 0)        1
  (0, 1)        2
  (1, 2)        3
  (2, 0)        1
  (2, 2)        4

git add . (add all files in this directory)

git add -all (add all files in all directories)

git add -N can be helpful for for listing which ones for later....

I resolved by removing @Basic(optional = false) property or just update boolean @Basic(optional = true)

Two solutions 1. use merge if you want to update the object 2. use save if you want to just save new object (make sure identity is null to let hibernate or database generate it) 3. if you are using mapping like
@OneToOne(fetch = FetchType.EAGER,cascade=CascadeType.ALL) @JoinColumn(name = "stock_id")

Then use CascadeType.ALL to CascadeType.MERGE

It takes color value from your Res/Values/Colors.xml -> colorAccent if you change it, your progressBar color changes aswell.

Mostly in Hibernate , need to add the Entity class in hibernate.cfg.xml like-

<hibernate-configuration>
  <session-factory>

    ....
    <mapping class="xxx.xxx.yourEntityName"/>
 </session-factory>
</hibernate-configuration>

Well, I don't have a function in python but I have a function in C which you can easily convert to python, in the below c function extended euclidian algorithm is used to calculate inverse mod.

int imod(int a,int n){
int c,i=1;
while(1){
    c = n * i + 1;
    if(c%a==0){
        c = c/a;
        break;
    }
    i++;
}
return c;}

Python Function

def imod(a,n):
  i=1
  while True:
    c = n * i + 1;
    if(c%a==0):
      c = c/a
      break;
    i = i+1

  return c

Reference to the above C function is taken from the following link C program to find Modular Multiplicative Inverse of two Relatively Prime Numbers

For folks who find this posting through the search engines, another possible cause of this problem is from importing the wrong package version of @Transient. Make sure that you import javax.persistence.transient and not some other package.

It looks like, cargo can have one or more item. Each item would have a reference to its corresponding cargo.

From the log, item object is inserted first and then an attempt is made to update the cargo object (which does not exist).

I guess what you actually want is cargo object to be created first and then the item object to be created with the id of the cargo object as the reference - so, essentally re-look at the save() method in the Action class.

What you are referring to is metadata, data about data. I had this same issue for the project I am currently working on and had to spend some time trying to figure it out. It's too much information to post here, but below are two links you may find useful. They do reference the Symfony framework, but are based on the Doctrine ORM.

Good luck, and nice Metallica references!

If you anticipate this rather unwanted behaviour, then one away around it would be to pass an extra parameter from the jQuery.trigger() to the checkbox's click handler. This extra parameter is to notify the click handler that click has been triggered programmatically, rather than by the user directly clicking on the checkbox itself. The checkbox's click handler can then invert the reported check status.

So here's how I'd trigger the click event on a checkbox with the ID "myCheckBox". Note that I'm also passing an object parameter with an single member, nonUI, which is set to true:

$("#myCheckbox").trigger('click', {nonUI : true})

And here's how I handle that in the checkbox's click event handler. The handler function checks for the presence of the nonUI object as its second parameter. (The first parameter is always the event itself.) If the parameter is present and set to true then I invert the reported .checked status. If no such parameter is passed in - which there won't be if the user simply clicked on the checkbox in the UI - then I report the actual .checked status:

$("#myCheckbox").click(function(e, parameters) {
   var nonUI = false;
        try {
            nonUI = parameters.nonUI;
        } catch (e) {}
        var checked = nonUI ? !this.checked : this.checked;
        alert('Checked = ' + checked);
    });

I've tested with Chrome, Firefox and IE 8.

The entity which has the table with foreign key in the database is the owning entity and the other table, being pointed at, is the inverse entity.

This version is 26% shorter than yours but functions identically, even for redundant/ambiguous values (returns the first match, as yours does). However, it is probably twice as slow as yours, because it creates a list from the dict twice.

key = dict_obj.keys()[dict_obj.values().index(value)]

Or if you prefer brevity over readability you can save one more character with

key = list(dict_obj)[dict_obj.values().index(value)]

And if you prefer efficiency, @PaulMcGuire's approach is better. If there are lots of keys that share the same value it's more efficient not to instantiate that list of keys with a list comprehension and instead use use a generator:

key = (key for key, value in dict_obj.items() if value == 'value').next()

def base(decimal ,base) :
    list = "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ"
    other_base = ""
    while decimal != 0 :
        other_base = list[decimal % base] + other_base
        decimal    = decimal / base
    if other_base == "":
        other_base = "0"
    return other_base

print base(31 ,16)

output:

"1F"

In res/color place a file "text_selector.xml":

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:color="@color/blue" android:state_focused="true" />
    <item android:color="@color/blue" android:state_selected="true" />
    <item android:color="@color/green" />
</selector>

Then in TextView use it:

<TextView
    android:id="@+id/value_1"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:text="Text"
    android:textColor="@color/text_selector"
    android:textSize="15sp"
    />

And in code you'll need to set a click listener.

private var isPressed = false

private fun TextView.setListener() {
    this.setOnClickListener { v ->
        run {
            if (isPressed) {
                v.isSelected = false
                v.clearFocus()
            } else {
                v.isSelected = true
                v.requestFocus()
            }
            isPressed = !isPressed
        }
    }
}

override fun onResume() {
    super.onResume()
    textView.setListener()
}

override fun onPause() {
    textView.setOnClickListener(null)
    super.onPause()
}

Sorry if there are errors, I changed a code before publishing and didn't check.

Add one more property in your view model, which will return reverse value. And bind that to button. Like;

in view model:

public bool IsNotReadOnly{get{return !IsReadOnly;}}

in xaml:

IsEnabled="{Binding IsNotReadOnly"}

Why don't you try to code it yourself? Take it as a challenge. :)

when you want to write a 1D Array in a Excel sheet you have to transpose it and you don't have to create a 2D array with 1 column ([n, 1]) as I read above! Here is a example of code :

You may want to check out the jblas project. It's a relatively new Java library that uses BLAS, LAPACK and ATLAS for high-performance matrix operations.

The developer has posted some benchmarks in which jblas comes off favourably against MTJ and Colt.

A good way of reducing the number of collision checks is to split the screen into different sections. You then only compare each ball to the balls in the same section.

If you want to avoid the mem cost of using the exec command, I believe you can do better with xargs. I think the following is a more efficient alternative to

find foo -type f ! -name '*Music*' -exec cp {} bar \; # new proc for each exec



find . -maxdepth 1 -name '*Music*' -prune -o -print0 | xargs -0 -i cp {} dest/

You should have a look at numpy if you do matrix manipulation. This is a module mainly written in C, which will be much faster than programming in pure python. Here is an example of how to invert a matrix, and do other matrix manipulation.

from numpy import matrix
from numpy import linalg
A = matrix( [[1,2,3],[11,12,13],[21,22,23]]) # Creates a matrix.
x = matrix( [[1],[2],[3]] )                  # Creates a matrix (like a column vector).
y = matrix( [[1,2,3]] )                      # Creates a matrix (like a row vector).
print A.T                                    # Transpose of A.
print A*x                                    # Matrix multiplication of A and x.
print A.I                                    # Inverse of A.
print linalg.solve(A, x)     # Solve the linear equation system.

You can also have a look at the array module, which is a much more efficient implementation of lists when you have to deal with only one data type.

In PCRE and similar variants, you can actually create a regex that matches any line not containing a value:

^(?:(?!Andrea).)*$

This is called a tempered greedy token. The downside is that it doesn't perform well.

Since it returns tuples (and can use tons of memory), the zip(*zipped) trick seems more clever than useful, to me.

Here's a function that will actually give you the inverse of zip.

def unzip(zipped):
    """Inverse of built-in zip function.
    Args:
        zipped: a list of tuples

    Returns:
        a tuple of lists

    Example:
        a = [1, 2, 3]
        b = [4, 5, 6]
        zipped = list(zip(a, b))

        assert zipped == [(1, 4), (2, 5), (3, 6)]

        unzipped = unzip(zipped)

        assert unzipped == ([1, 2, 3], [4, 5, 6])

    """

    unzipped = ()
    if len(zipped) == 0:

You can do it without setlocal, because of the setlocal command the variable won't survive an endlocal because it was created in setlocal. In this way the variable will be defined the right way.

To do that use this code:

set var1=A

set var2=B

set AB=hi

call set newvar=%%%var1%%var2%%%

echo %newvar% 

Note: You MUST use call before you set the variable or it won't work.

You have to define a PersistentVolume providing disc space to be consumed by the PersistentVolumeClaim.

When using storageClass Kubernetes is going to enable "Dynamic Volume Provisioning" which is not working with the local file system.

To solve your issue:

• Provide a PersistentVolume fulfilling the constraints of the claim (a size >= 100Mi)
• Remove the storageClass-line from the PersistentVolumeClaim
• Remove the StorageClass from your cluster

How do these pieces play together?

At creation of the deployment state-description it is usually known which kind (amount, speed, ...) of storage that application will need.
To make a deployment versatile you'd like to avoid a hard dependency on storage. Kubernetes' volume-abstraction allows you to provide and consume storage in a standardized way.

The PersistentVolumeClaim is used to provide a storage-constraint alongside the deployment of an application.

The PersistentVolume offers cluster-wide volume-instances ready to be consumed ("bound"). One PersistentVolume will be bound to one claim. But since multiple instances of that claim may be run on multiple nodes, that volume may be accessed by multiple nodes.

A PersistentVolume without StorageClass is considered to be static.

"Dynamic Volume Provisioning" alongside with a StorageClass allows the cluster to provision PersistentVolumes on demand. In order to make that work, the given storage provider must support provisioning - this allows the cluster to request the provisioning of a "new" PersistentVolume when an unsatisfied PersistentVolumeClaim pops up.

Example PersistentVolume

In order to find how to specify things you're best advised to take a look at the API for your Kubernetes version, so the following example is build from the API-Reference of K8S 1.17:

apiVersion: v1
kind: PersistentVolume
metadata:
  name: ckan-pv-home
  labels:
    type: local
spec:
  capacity:
    storage: 100Mi
  hostPath:
    path: "/mnt/data/ckan"

The PersistentVolumeSpec allows us to define multiple attributes. I chose a hostPath volume which maps a local directory as content for the volume. The capacity allows the resource scheduler to recognize this volume as applicable in terms of resource needs.

Additional Resources:

        list2.stream().map(x->x.getStr()).collect(Collectors.toSet())
        .contains(str1)).collect(Collectors.toList());

This may work more efficient.

I've been frustrated by this problem as well. Find/Replace can be helpful though, because if you don't put anything in the "replace" field it will replace with an -actual- NULL. So the steps would be something along the lines of:

1: Place some unique string in your formula in place of the NULL output (i like to use a password-like string)

2: Run your formula

3: Open Find/Replace, and fill in the unique string as the search value. Leave "replace with" blank

4: Replace All

Obviously, this has limitations. It only works when the context allows you to do a find/replace, so for more dynamic formulas this won't help much. But, I figured I'd put it up here anyway.

Is this going to put people off coming to Scala?

I don't think it is the main factor that will affect how popular Scala will become, because Scala has a lot of power and its syntax is not as foreign to a Java/C++/PHP programmer as Haskell, OCaml, SML, Lisps, etc..

But I do think Scala's popularity will plateau at less than where Java is today, because I also think the next mainstream language must be much simplified, and the only way I see to get there is pure immutability, i.e. declarative like HTML, but Turing complete. However, I am biased because I am developing such a language, but I only did so after ruling out over a several month study that Scala could not suffice for what I needed.

Is this going to give Scala a bad name in the commercial world as an academic plaything that only dedicated PhD students can understand? Are CTOs and heads of software going to get scared off?

I don't think Scala's reputation will suffer from the Haskell complex. But I think that some will put off learning it, because for most programmers, I don't yet see a use case that forces them to use Scala, and they will procrastinate learning about it. Perhaps the highly-scalable server side is the most compelling use case.

And, for the mainstream market, first learning Scala is not a "breath of fresh air", where one is writing programs immediately, such as first using HTML or Python. Scala tends to grow on you, after one learns all the details that one stumbles on from the start. However, maybe if I had read Programming in Scala from the start, my experience and opinion of the learning curve would have been different.

Was the library re-design a sensible idea?

Definitely.

If you're using Scala commercially, are you worried about this? Are you planning to adopt 2.8 immediately or wait to see what happens?

I am using Scala as the initial platform of my new language. I probably wouldn't be building code on Scala's collection library if I was using Scala commercially otherwise. I would create my own category theory based library, since the one time I looked, I found Scalaz's type signatures even more verbose and unwieldy than Scala's collection library. Part of that problem perhaps is Scala's way of implementing type classes, and that is a minor reason I am creating my own language.

I decided to write this answer, because I wanted to force myself to research and compare Scala's collection class design to the one I am doing for my language. Might as well share my thought process.

The 2.8 Scala collections use of a builder abstraction is a sound design principle. I want to explore two design tradeoffs below.

1. WRITE-ONLY CODE: After writing this section, I read Carl Smotricz's comment which agrees with what I expect to be the tradeoff. James Strachan and davetron5000's comments concur that the meaning of That (it is not even That[B]) and the mechanism of the implicit is not easy to grasp intuitively. See my use of monoid in issue #2 below, which I think is much more explicit. Derek Mahar's comment is about writing Scala, but what about reading the Scala of others that is not "in the common cases".

   One criticism I have read about Scala, is that it is easier to write it, than read the code that others have written. And I find this to be occasionally true for various reasons (e.g. many ways to write a function, automatic closures, Unit for DSLs, etc), but I am undecided if this is major factor. Here the use of implicit function parameters has pluses and minuses. On the plus side, it reduces verbosity and automates selection of the builder object. In Odersky's example the conversion from a BitSet, i.e. Set[Int], to a Set[String] is implicit. The unfamiliar reader of the code might not readily know what the type of collection is, unless they can reason well about the all the potential invisible implicit builder candidates which might exist in the current package scope. Of course, the experienced programmer and the writer of the code will know that BitSet is limited to Int, thus a map to String has to convert to a different collection type. But which collection type? It isn't specified explicitly.

2. AD-HOC COLLECTION DESIGN: After writing this section, I read Tony Morris's comment and realized I am making nearly the same point. Perhaps my more verbose exposition will make the point more clear.

   In "Fighting Bit Rot with Types" Odersky & Moors, two use cases are presented. They are the restriction of BitSet to Int elements, and Map to pair tuple elements, and are provided as the reason that the general element mapping function, A => B, must be able to build alternative destination collection types. However, afaik this is flawed from a category theory perspective. To be consistent in category theory and thus avoid corner cases, these collection types are functors, in which each morphism, A => B, must map between objects in the same functor category, List[A] => List[B], BitSet[A] => BitSet[B]. For example, an Option is a functor that can be viewed as a collection of sets of one Some( object ) and the None. There is no general map from Option's None, or List's Nil, to other functors which don't have an "empty" state.

   There is a tradeoff design choice made here. In the design for collections library of my new language, I chose to make everything a functor, which means if I implement a BitSet, it needs to support all element types, by using a non-bit field internal representation when presented with a non-integer type parameter, and that functionality is already in the Set which it inherits from in Scala. And Map in my design needs to map only its values, and it can provide a separate non-functor method for mapping its (key,value) pair tuples. One advantage is that each functor is then usually also an applicative and perhaps a monad too. Thus all functions between element types, e.g. A => B => C => D => ..., are automatically lifted to the functions between lifted applicative types, e.g. List[A] => List[B] => List[C] => List[D] => .... For mapping from a functor to another collection class, I offer a map overload which takes a monoid, e.g. Nil, None, 0, "", Array(), etc.. So the builder abstraction function is the append method of a monoid and is supplied explicitly as a necessary input parameter, thus with no invisible implicit conversions. (Tangent: this input parameter also enables appending to non-empty monoids, which Scala's map design can't do.) Such conversions are a map and a fold in the same iteration pass. Also I provide a traversable, in the category sense, "Applicative programming with effects" McBride & Patterson, which also enables map + fold in a single iteration pass from any traversable to any applicative, where most every collection class is both. Also the state monad is an applicative and thus is a fully generalized builder abstraction from any traversable.

   So afaics the Scala collections is "ad-hoc" in the sense that it is not grounded in category theory, and category theory is the essense of higher-level denotational semantics. Although Scala's implicit builders are at first appearance "more generalized" than a functor model + monoid builder + traversable -> applicative, they are afaik not proven to be consistent with any category, and thus we don't know what rules they follow in the most general sense and what the corner cases will be given they may not obey any category model. It is simply not true that adding more variables makes something more general, and this was one of huge benefits of category theory is it provides rules by which to maintain generality while lifting to higher-level semantics. A collection is a category.

   I read somewhere, I think it was Odersky, as another justification for the library design, is that programming in a pure functional style has the cost of limited recursion and speed where tail recursion isn't used. I haven't found it difficult to employ tail recursion in every case that I have encountered so far.

Additionally I am carrying in my mind an incomplete idea that some of Scala's tradeoffs are due to trying to be both an mutable and immutable language, unlike for example Haskell or the language I am developing. This concurs with Tony Morris's comment about for comprehensions. In my language, there are no loops and no mutable constructs. My language will sit on top of Scala (for now) and owes much to it, and this wouldn't be possible if Scala didn't have the general type system and mutability. That might not be true though, because I think Odersky & Moors ("Fighting Bit Rot with Types") are incorrect to state that Scala is the only OOP language with higher-kinds, because I verified (myself and via Bob Harper) that Standard ML has them. Also appears SML's type system may be equivalently flexible (since 1980s), which may not be readily appreciated because the syntax is not so much similar to Java (and C++/PHP) as Scala. In any case, this isn't a criticism of Scala, but rather an attempt to present an incomplete analysis of tradeoffs, which is I hope germane to the question. Scala and SML don't suffer from Haskell's inability to do diamond multiple inheritance, which is critical and I understand is why so many functions in the Haskell Prelude are repeated for different types.

if value.to_s == 'true'
  true
elsif value.to_s == 'false'
  false
end

d = {} is an empty object right now.

And d[a] is also an empty object.

It does not have any key values. So you should initialize the key values to this.

d[a] = {
greetings:'',
data:''
}

arr.sort(function(a,b) {
    a = a.toLowerCase();
    b = b.toLowerCase();
    if( a == b) return 0;
    if( a > b) return 1;
    return -1;
});

In above function, if we just compare when lower case two value a and b, we will not have the pretty result.

Example, if array is [A, a, B, b, c, C, D, d, e, E] and we use the above function, we have exactly that array. It's not changed anything.

To have the result is [A, a, B, b, C, c, D, d, E, e], we should compare again when two lower case value is equal:

function caseInsensitiveComparator(valueA, valueB) {
    var valueALowerCase = valueA.toLowerCase();
    var valueBLowerCase = valueB.toLowerCase();

    if (valueALowerCase < valueBLowerCase) {
        return -1;
    } else if (valueALowerCase > valueBLowerCase) {
        return 1;
    } else { //valueALowerCase === valueBLowerCase
        if (valueA < valueB) {
            return -1;
        } else if (valueA > valueB) {
            return 1;
        } else {
            return 0;
        }
    }
}

<label>
    <input
        type="checkbox"
        onclick="$('input[type=checkbox]').attr('checked', $(this).is(':checked'));"
    />
    Check all
</label>

I believe it's:

git checkout master
git checkout -b good_quickfix2
git cherry-pick quickfix2^
git cherry-pick quickfix2

You can find the min/max index and value at the same time if you enumerate the items in the list, but perform min/max on the original values of the list. Like so:

import operator
min_index, min_value = min(enumerate(values), key=operator.itemgetter(1))
max_index, max_value = max(enumerate(values), key=operator.itemgetter(1))

This way the list will only be traversed once for min (or max).

Actually, neither statement says anything about heap or stack. The code

Object o;

creates one of the following, depending on its context:

• a local variable with automatic storage,
• a static variable at namespace or file scope,
• a member variable that designates the subobject of another object.

This means that the storage location is determined by the context in which the object is defined. In addition, the C++ standard does not talk about stack vs heap storage. Instead, it talks about storage duration, which can be either automatic, dynamic, static or thread-local. However, most implementations implement automatic storage via the call stack, and dynamic storage via the heap.

Local variables, which have automatic storage, are thus created on the stack. Static (and thread-local) objects are generally allocated in their own memory regions, neither on the stack nor on the heap. And member variables are allocated wherever the object they belong to is allocated. They have their containing object’s storage duration.

To illustrate this with an example:

struct Foo {
    Object o;
};

Foo foo;

int main() {
    Foo f;
    Foo* p = new Foo;
    Foo* pf = &f;
}

Now where is the object Foo::o (that is, the subobject o of an object of class Foo) created? It depends:

• foo.o has static storage because foo has static storage, and therefore lives neither on the stack nor on the heap.
• f.o has automatic storage since f has automatic storage (= it lives on the stack).
• p->o has dynamic storage since *p has dynamic storage (= it lives on the heap).
• pf->o is the same object as f.o because pf points to f.

In fact, both p and pf in the above have automatic storage. A pointer’s storage is indistinguishable from any other object’s, it is determined by context. Furthermore, the initialising expression has no effect on the pointer storage.

The pointee (= what the pointer points to) is a completely different matter, and could refer to any kind of storage: *p is dynamic, whereas *pf is automatic.

I think you need the SCHEDULER_ADMIN role to see the dba_scheduler tables (however this may grant you too may rights)

ALTER TABLE `tbl_celebrity_rows` ADD CONSTRAINT `tbl_celebrity_rows_ibfk_1` FOREIGN KEY (`celebrity_id`) 
REFERENCES `tbl_celebrities`(`id`) ON DELETE CASCADE ON UPDATE RESTRICT;

I found a simple way around this in 2005. Here are my steps:

1. Create a string parameter with values ‘Y’ and ‘N’ called ‘PageBreaks’.
2. Add a group level above the group (value) which was used to split the data to the multiple sheets in Excel.
3. Inserted into the first textbox field for this group, the expression for the ‘PageBreaks’ as such… =IIF(Parameters!PageBreaks.Value="Y",Fields!DISP_PROJECT.Value,"") Note: If the parameter =’Y’ then you will get the multiple sheets for each different value. Otherwise the field is NULL for every group record (which causes only one page break at the end).
4. Change the visibility hidden value of the new grouping row to ‘True’.
5. NOTE: When you do this it will also determine whether or not you have a page break in the view, but my users love it since they have the control.

I prefer to use

<input type='date' id='hasta' value='<?php echo date('Y-m-d');?>'>

that works well

I was searching for this answer for a while. Now I got it in the official gulp documentation.

If you want to perform a gulp task when the last one is complete, you have to return a stream:

gulp.task('wiredep', ['dev-jade'], function () {_x000D_
    var stream = gulp.src(paths.output + '*.html')_x000D_
        .pipe($.wiredep())_x000D_
        .pipe(gulp.dest(paths.output));_x000D_
_x000D_
    return stream; // execute next task when this is completed_x000D_
});_x000D_
_x000D_
// First will execute and complete wiredep task_x000D_
gulp.task('prod-jade', ['wiredep'], function() {_x000D_
    gulp.src(paths.output + '**/*.html')_x000D_
        .pipe($.minifyHtml())_x000D_
        .pipe(gulp.dest(paths.output));_x000D_
});

The problem here is that the "on" is applied to all elements that exists AT THE TIME. When you create an element dynamically, you need to run the on again:

$('form').on('submit',doFormStuff);

createNewForm();

// re-attach to all forms
$('form').off('submit').on('submit',doFormStuff);

Since forms usually have names or IDs, you can just attach to the new form as well. If I'm creating a lot of dynamic stuff, I'll include a setup or bind function:

function bindItems(){
    $('form').off('submit').on('submit',doFormStuff); 
    $('button').off('click').on('click',doButtonStuff);
}   

So then whenever you create something (buttons usually in my case), I just call bindItems to update everything on the page.

createNewButton();
bindItems();

I don't like using 'body' or document elements because with tabs and modals they tend to hang around and do things you don't expect. I always try to be as specific as possible unless its a simple 1 page project.

Please see the following link - here is where I found a solution that worked for me.

Rendering problems in Android Studio v 1.1 / 1.2

Changing the Android Version when rendering layouts worked for me - I flipped it back to 21 and my "Hello World" app then rendered the basic activity_main.xml OK - at 22 I got this error. I borrowed the image from this posting to show you where to click in the Design tab of the XML preview. What is wierd is that when I flip back to 22 the problem is still gone :-).

TreeSet would not work because they do not allow duplicates plus they do not provide method to fetch element at specific position. PriorityQueue would not work because it does not allow fetching elements at specific position which is a basic requirement for a list. I think you need to implement your own algorithm to maintain a sorted list in Java with O(logn) insert time, unless you do not need duplicates. Maybe a solution could be using a TreeMap where the key is a subclass of the item overriding the equals method so that duplicates are allowed.

Adding this here as it doesn't seem to be here.

Aside from the excellent solution of form.append("blob",blob, filename); you can also turn the blob into a File instance:

var blob = new Blob([JSON.stringify([0,1,2])], {type : 'application/json'});
var fileOfBlob = new File([blob], 'aFileName.json');
form.append("upload", fileOfBlob);

The view you get passed in on onClick() is the Button you are looking for.

public void onClick(View v) {
    // 1) Possibly check for instance of first 
    Button b = (Button)v;
    String buttonText = b.getText().toString();
}

1) If you are using a non-anonymous class as onClickListener, you may want to check for the type of the view before casting it, as it may be something different than a Button.

This questions is already answered here. Just put height: 100% in both the div and the container td.

You add a

float: left;

to the style of the 3 elements and make sure the parent container has

overflow: hidden; position: relative;

this makes sure the floats take up actual space.

<html>
    <head>
        <title>Website Title </title>
    </head>
    <body>
        <div id="the-whole-thing" style="position: relative; overflow: hidden;">
            <div id="leftThing" style="position: relative; width: 25%; background-color: blue; float: left;">
                Left Side Menu
            </div>
            <div id="content" style="position: relative; width: 50%; background-color: green; float: left;">
                Random Content
            </div>
            <div id="rightThing" style="position: relative; width: 25%; background-color: yellow; float: left;">
                Right Side Menu
            </div>
        </div>
    </body>
</html>

Also please note that the width: 100% and height: 100% need to be removed from the container, otherwise the 3rd block will wrap to a 2nd line.

I just encountered this issue and would recommend csvsql (releases) for bulk imports to Postgres. To perform a bulk insert you'd simply createdb and then use csvsql, which connects to your database and creates individual tables for an entire folder of CSVs.

$ createdb test 
$ csvsql --db postgresql:///test --insert examples/*.csv

By default require() is not a valid function in client side javascript. I recommend you look into require.js as this does extend the client side to provide you with that function.

in my case .. setting parameterLimit:50000 fixed the problem

app.use( bodyParser.json({limit: '50mb'}) );
app.use(bodyParser.urlencoded({
  limit: '50mb',
  extended: true,
  parameterLimit:50000
}));

You might want to check HTML frames, which can do pretty much exactly what you are looking for. They are considered outdated however.

Add System.Configuration as a reference.

For some bizarre reason it's not included by default.

See http://angular-ui.github.io/bootstrap/#/collapse

function CollapseDemoCtrl($scope) {
  $scope.isCollapsed = false;
}



<div ng-controller="CollapseDemoCtrl">
    <button class="btn" ng-click="isCollapsed = !isCollapsed">Toggle collapse</button>
    <hr>
    <div collapse="isCollapsed">
        <div class="well well-large">Some content</div> 
    </div>
</div>

I came with a pretty simple solution. I'm not sure whether it is the correct way to do it but it works in a practical sense. Let's directly watch what we want to be rendered. For example in a directive that includes some ng-repeats, I would watch out for the length of text (you may have other things!) of paragraphs or the whole html. The directive will be like this:

.directive('myDirective', [function () {
    'use strict';
    return {

        link: function (scope, element, attrs) {
            scope.$watch(function(){
               var whole_p_length = 0;
               var ps = element.find('p');
                for (var i=0;i<ps.length;i++){
                    if (ps[i].innerHTML == undefined){
                        continue
                    }
                    whole_p_length+= ps[i].innerHTML.length;
                }
                //it could be this too:  whole_p_length = element[0].innerHTML.length; but my test showed that the above method is a bit faster
                console.log(whole_p_length);
                return whole_p_length;
            }, function (value) {   
                //Code you want to be run after rendering changes
            });
        }
}]);

NOTE that the code actually runs after rendering changes rather complete rendering. But I guess in most cases you can handle the situations whenever rendering changes happen. Also you could think of comparing this ps length (or any other measure) with your model if you want to run your code only once after rendering completed. I appreciate any thoughts/comments on this.

You can edit style with pure Javascript. No library needed, supported by all browsers except IE where you need to set to '' instead of null (see comments).

var element = document.getElementById('sample_id');

element.style.width = null;
element.style.height = null;

For more information, you can refer to HTMLElement.style documentation on MDN.

I just discovered the Hmisc package:

Contains many functions useful for data analysis, high-level graphics, utility operations, functions for computing sample size and power, importing and annotating datasets, imputing missing values, advanced table making, variable clustering, character string manipulation, conversion of R objects to LaTeX and html code, and recoding variables.

library(Hmisc)    
plot(...)
minor.tick(nx=10, ny=10) # make minor tick marks (without labels) every 10th

Note: the accepted solution is now outdated and part of legacy code. http://legacy.datatables.net/ref The solutions might not be appropriate for those working with the newer versions of DataTables (its legacy now) For the newer solution: you could use: https://datatables.net/reference/api/columns().visible()

alternatives you could implement a button: https://datatables.net/extensions/buttons/built-in look at the last option under the link provided that allows having a button that could toggle column visibility.

It sounds like you want an out of source build. There are a couple of ways you can create an out of source build.

1. Do what you were doing, run

   cd /path/to/my/build/folder
   cmake /path/to/my/source/folder
   

   which will cause cmake to generate a build tree in /path/to/my/build/folder for the source tree in /path/to/my/source/folder.

   Once you've created it, cmake remembers where the source folder is - so you can rerun cmake on the build tree with

   cmake /path/to/my/build/folder
   

   or even

   cmake .
   

   if your current directory is already the build folder.

2. For CMake 3.13 or later, use these options to set the source and build folders

   cmake -B/path/to/my/build/folder -S/path/to/my/source/folder
   

3. For older CMake, use some undocumented options to set the source and build folders:

   cmake -B/path/to/my/build/folder -H/path/to/my/source/folder
   

   which will do exactly the same thing as (1), but without the reliance on the current working directory.

CMake puts all of its outputs in the build tree by default, so unless you are liberally using ${CMAKE_SOURCE_DIR} or ${CMAKE_CURRENT_SOURCE_DIR} in your cmake files, it shouldn't touch your source tree.

The biggest thing that can go wrong is if you have previously generated a build tree in your source tree (i.e. you have an in source build). Once you've done this the second part of (1) above kicks in, and cmake doesn't make any changes to the source or build locations. Thus, you cannot create an out-of-source build for a source directory with an in-source build. You can fix this fairly easily by removing (at a minimum) CMakeCache.txt from the source directory. There are a few other files (mostly in the CMakeFiles directory) that CMake generates that you should remove as well, but these won't cause cmake to treat the source tree as a build tree.

Since out-of-source builds are often more desirable than in-source builds, you might want to modify your cmake to require out of source builds:

# Ensures that we do an out of source build

MACRO(MACRO_ENSURE_OUT_OF_SOURCE_BUILD MSG)
     STRING(COMPARE EQUAL "${CMAKE_SOURCE_DIR}"
     "${CMAKE_BINARY_DIR}" insource)
     GET_FILENAME_COMPONENT(PARENTDIR ${CMAKE_SOURCE_DIR} PATH)
     STRING(COMPARE EQUAL "${CMAKE_SOURCE_DIR}"
     "${PARENTDIR}" insourcesubdir)
    IF(insource OR insourcesubdir)
        MESSAGE(FATAL_ERROR "${MSG}")
    ENDIF(insource OR insourcesubdir)
ENDMACRO(MACRO_ENSURE_OUT_OF_SOURCE_BUILD)

MACRO_ENSURE_OUT_OF_SOURCE_BUILD(
    "${CMAKE_PROJECT_NAME} requires an out of source build."
)

The above macro comes from a commonly used module called MacroOutOfSourceBuild. There are numerous sources for MacroOutOfSourceBuild.cmake on google but I can't seem to find the original and it's short enough to include here in full.

Unfortunately cmake has usually written a few files by the time the macro is invoked, so although it will stop you from actually performing the build you will still need to delete CMakeCache.txt and CMakeFiles.

You may find it useful to set the paths that binaries, shared and static libraries are written to - in which case see how do I make cmake output into a 'bin' dir? (disclaimer, I have the top voted answer on that question...but that's how I know about it).

In my case, I had an error in my AndroidManifest.xml. Others have said that your XML files must be free from errors, but I was only looking in the res/ folder. Find and fix as many possible errors and the problem may well resolve itself.

Quick answer:

<ImageView
        android:id="@+id/imageView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:scaleType="center"
        android:src="@drawable/yourImage"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent" />

Step 1: Restart VS Code as an adminstrator

(click the windows key, search for "Visual Studio Code", right click, and you'll see the administrator option)

Step 2: In your VS code powershell terminal run Set-ExecutionPolicy Unrestricted

Strace Overview
strace can be seen as a light weight debugger. It allows a programmer / user to quickly find out how a program is interacting with the OS. It does this by monitoring system calls and signals.

Uses
Good for when you don't have source code or don't want to be bothered to really go through it.
Also, useful for your own code if you don't feel like opening up GDB, but are just interested in understanding external interaction.

A good little introduction
I ran into this intro to strace use just the other day: strace hello world

I am using AngluarJS in html5 mode. I found following solution as most reliable:

Use angular-google-analytics library. Initialize it with something like:

//Do this in module that is always initialized on your webapp    
angular.module('core').config(["AnalyticsProvider",
  function (AnalyticsProvider) {
    AnalyticsProvider.setAccount(YOUR_GOOGLE_ANALYTICS_TRACKING_CODE);

    //Ignoring first page load because of HTML5 route mode to ensure that page view is called only when you explicitly call for pageview event
    AnalyticsProvider.ignoreFirstPageLoad(true);
  }
]);

After that, add listener on $stateChangeSuccess' and send trackPage event.

angular.module('core').run(['$rootScope', '$location', 'Analytics', 
    function($rootScope, $location, Analytics) {
        $rootScope.$on('$stateChangeSuccess', function(event, toState, toParams, fromState, fromParams, options) {
            try {
                Analytics.trackPage($location.url());
            }
            catch(err) {
              //user browser is disabling tracking
            }
        });
    }
]);

At any moment, when you have your user initalized you can inject Analytics there and make call:

Analytics.set('&uid', user.id);

Error 127 means one of two things:

1. file not found: the path you're using is incorrect. double check that the program is actually in your $PATH, or in this case, the relative path is correct -- remember that the current working directory for a random terminal might not be the same for the IDE you're using. it might be better to just use an absolute path instead.
2. ldso is not found: you're using a pre-compiled binary and it wants an interpreter that isn't on your system. maybe you're using an x86_64 (64-bit) distro, but the prebuilt is for x86 (32-bit). you can determine whether this is the answer by opening a terminal and attempting to execute it directly. or by running file -L on /bin/sh (to get your default/native format) and on the compiler itself (to see what format it is).

if the problem is (2), then you can solve it in a few diff ways:

1. get a better binary. talk to the vendor that gave you the toolchain and ask them for one that doesn't suck.
2. see if your distro can install the multilib set of files. most x86_64 64-bit distros allow you to install x86 32-bit libraries in parallel.
3. build your own cross-compiler using something like crosstool-ng.
4. you could switch between an x86_64 & x86 install, but that seems a bit drastic ;).

You can use a regular expression as below:

return string1.toLowerCase().replace(/^[a-zA-z]|\s(.)/ig, L => L.toUpperCase());

I made the following code so that even beginners can understand. Just copy the code and read comments. Note that message to be send is declared as a global variable which you can change just before sending the message. General changes can be done in Handler function.

The algorithm choice probably doesn't matter that much. I'd use AES since it's been better researched. What's much more important is choosing the right operation mode and key derivation function.

You might want to take a look at the TrueCrypt format specification for inspiration if you want fast random access. If you don't need random access than XTS isn't the optimal mode, since it has weaknesses other modes don't. And you might want to add some kind of integrity check(or message authentication code) too.

I would suggest that you use a dictionary like so:

arr = {}

arr[1] = (1, 2, 4)
arr[18] = (3, 4, 5)

print(arr[1])
>>> (1, 2, 4)

If you're not sure an entry is defined in the dictionary, you'll need a validation mechanism when calling "arr[x]", e.g. try-except.

in my case, i have a cdn,and i am going to place all my processed static files (js,imgs,fonts...) into my cdn,suppose the url is http://my.cdn.com/

so if there is a js file which is the orginal refer url in html is './js/my.js' it should became http://my.cdn.com/js/my.js in production environment

in that case,what i need to do is just set publicpath equals http://my.cdn.com/ and webpack will automatic add that prefix

DataTable dr_art_line_2 = ds.Tables["QuantityInIssueUnit"];

for (int i = 0; i < dr_art_line_2.Rows.Count; i++)
{
    QuantityInIssueUnit_value = Convert.ToInt32(dr_art_line_2.Rows[i]["columnname"]);
    //Similarly for QuantityInIssueUnit_uom.
}

Slight change to Nico's, since .children() will return an empty set if we're referencing a text element like an h1 or p. So we'll use .contents() instead, and use this instead of $(this) since we're creating a method on a jQuery object.

$.fn.textWidth = function(){
    var contents = this.contents(),
        wrapper  = '<span style="display: inline-block;" />',
        width    = '';

    contents.wrapAll(wrapper);
    width = contents.parent().width(); // parent is now the wrapper
    contents.unwrap();
    return width;
    };

By default, unlike an exception, a warning doesn't interrupt.

After import warnings, it is possible to specify a Warnings class when generating a warning. If one is not specified, it is literally UserWarning by default.

>>> warnings.warn('This is a default warning.')
<string>:1: UserWarning: This is a default warning.

To simply use a preexisting class instead, e.g. DeprecationWarning:

>>> warnings.warn('This is a particular warning.', DeprecationWarning)
<string>:1: DeprecationWarning: This is a particular warning.

Creating a custom warning class is similar to creating a custom exception class:

>>> class MyCustomWarning(UserWarning):
...     pass
... 
... warnings.warn('This is my custom warning.', MyCustomWarning)

<string>:1: MyCustomWarning: This is my custom warning.

For testing, consider assertWarns or assertWarnsRegex.

As an alternative, especially for standalone applications, consider the logging module. It can log messages having a level of debug, info, warning, error, etc. Log messages having a level of warning or higher are by default printed to stderr.

<div style="background-color:#006600; width:300px; text-align:center; padding:50px 0px 50px 0px;">
<img src="imges/import.jpg" width="200" height="200"/>
</div>

In my case i never put return inside a arrow function so my code is follow

`<ProductConsumer>
   {(myvariable)=>{
      return  <h1>{myvariable}</h1>
   }}
</ProductConsumer> `

I'm guessing you want to center the box both vertically and horizontally, regardless of browser window size. Since you have a fixed width and height for the box, this should work:

Markup:

<div></div>

CSS:

div {
    height: 200px;
    width: 400px;
    background: black;

    position: fixed;
    top: 50%;
    left: 50%;
    margin-top: -100px;
    margin-left: -200px;
}

The div should remain in the center of the screen even if you resize the browser. Just replace the margin-top and margin-left with half of the height and width of your table.

Edit: Credit goes to CSS-Tricks, where I got the original idea.

Editing the hosts file is less of a pain when you run "ipconfig /flushdns" from the windows command prompt, instead of restarting your computer.

I couldn't get The DataRowAttribute to work in Visual Studio 2015, and this is what I ended up with:

[TestClass]
public class Tests
{
    private Foo _toTest;

    [TestInitialize]
    public void Setup()
    {
        this._toTest = new Foo();
    }

    [TestMethod]
    public void ATest()
    {
        this.Perform_ATest(1, 1, 2);
        this.Setup();

        this.Perform_ATest(100, 200, 300);
        this.Setup();

        this.Perform_ATest(817001, 212, 817213);
        this.Setup();
    }

    private void Perform_ATest(int a, int b, int expected)
    {
        // Obviously this would be way more complex...

        Assert.IsTrue(this._toTest.Add(a,b) == expected);
    }
}

public class Foo
{
    public int Add(int a, int b)
    {
        return a + b;
    }
}

The real solution here is to just use NUnit (unless you're stuck in MSTest like I am in this particular instance).

It is always ideal to use the json.dumps() method. To get rid of this error, I used the following code

json.dumps(YOUR_DICT_STRING).replace("'", '"')

            <xsl:value-of select="OU_COUNTRY"/>

Now, to your question:

how to compare two elements coming from xml as string

In Xpath 1.0 strings can be compared only for equality (or inequality), using the operator = and the function not() together with the operator =.

$str1 = $str2

evaluates to true() exactly when the string $str1 is equal to the string $str2.

not($str1 = $str2)

evaluates to true() exactly when the string $str1 is not equal to the string $str2.

There is also the != operator. It generally should be avoided because it has anomalous behavior whenever one of its operands is a node-set.

Now, the rules for comparing two element nodes are similar:

$el1 = $el2

evaluates to true() exactly when the string value of $el1 is equal to the string value of $el2.

not($el1 = $el2)

evaluates to true() exactly when the string value of $el1 is not equal to the string value of $el2.

However, if one of the operands of = is a node-set, then

 $ns = $str

evaluates to true() exactly when there is at least one node in the node-set $ns1, whose string value is equal to the string $str

$ns1 = $ns2

evaluates to true() exactly when there is at least one node in the node-set $ns1, whose string value is equal to the string value of some node from $ns2

Therefore, the expression:

OU_NAME='OU_ADDR1'

evaluates to true() only when there is at least one element child of the current node that is named OU_NAME and whose string value is the string 'OU_ADDR1'.

This is obviously not what you want!

Most probably you want:

OU_NAME=OU_ADDR1

This expression evaluates to true exactly there is at least one OU_NAME child of the current node and one OU_ADDR1 child of the current node with the same string value.

Finally, in XPath 2.0, strings can be compared also using the value comparison operators lt, le, eq, gt, ge and the inherited from XPath 1.0 general comparison operator =.

Trying to evaluate a value comparison operator when one or both of its arguments is a sequence of more than one item results in error.

Since you can just create and throw exceptions it could be as easy as

if ( word.contains(" ") )
{
     throw new RuntimeException ( "Word contains one or more spaces" ) ;
}

If you would like to be more formal, you can create an Exception class

class SpaceyWordException extends RuntimeException
{

}

Either way, if you use RuntimeException, your new Exception will be unchecked.

Use below function with below example for changing image size :

//Example : 
System.Net.Mime.MediaTypeNames.Image newImage = System.Net.Mime.MediaTypeNames.Image.FromFile("SampImag.jpg");
System.Net.Mime.MediaTypeNames.Image temImag = FormatImage(newImage, 100, 100);

//image size modification unction   
public static System.Net.Mime.MediaTypeNames.Image FormatImage(System.Net.Mime.MediaTypeNames.Image img, int outputWidth, int outputHeight)
{

    Bitmap outputImage = null;
    Graphics graphics = null;
    try
    {
         outputImage = new Bitmap(outputWidth, outputHeight, System.Drawing.Imaging.PixelFormat.Format16bppRgb555);
         graphics = Graphics.FromImage(outputImage);
         graphics.DrawImage(img, new Rectangle(0, 0, outputWidth, outputHeight),
         new Rectangle(0, 0, img.Width, img.Height), GraphicsUnit.Pixel);

         return outputImage;
     }
     catch (Exception ex)
     {
           return img;
     }
}

First ensure that hlsearch is enabled by issuing the following command

:set hlsearch

You can also add this to your .vimrc file as set

set hlsearch

now when you use the quick search mechanism in command mode or a regular search command, all results will be highlighted. To move forward between results, press 'n' to move backwards press 'N'

In normal mode, to perform a quick search for the word under the cursor and to jump to the next occurrence in one command press '*', you can also search for the word under the cursor and move to the previous occurrence by pressing '#'

In normal mode, quick search can also be invoked with the

/searchterm<Enter>

to remove highlights on ocuurences use, I have bound this to a shortcut in my .vimrc

:nohl

I see the status field on the jqXhr object, here is a fiddle with it working:

http://jsfiddle.net/magicaj/55HQq/3/

$.ajax({
    //...        
    success: function(data, textStatus, xhr) {
        console.log(xhr.status);
    },
    complete: function(xhr, textStatus) {
        console.log(xhr.status);
    } 
});

That works with :

 var element = document.getElementById('myElem');
 if (typeof (element) != undefined && typeof (element) != null && typeof (element) != 'undefined') {
     console.log('element exists');
 }
 else{
     console.log('element NOT exists');
 }

Also take a look at BackendPro

Ultimately you will probably end up writing something custom, but there's nothing wrong with borrowing concepts from DX Auth, Freak Auth, BackendPro, etc.

My experiences with the packaged apps is they are specific to certain structures and I have had problems integrating them into my own applications without requiring hacks, then if the pre-package has an update, I have to migrate them in.

I also use Smarty and ADOdb in my CI code, so no matter what I would always end up making major code changes.

My take on it...obviously, you've got to do something with the data you read in. If it involves writing it to the sheet, that'll be deadly slow with a normal For Loop. I came up with the following based upon a rehash of some of the items there, plus some help from the Chip Pearson website.

Reading in the text file (assuming you don't know the length of the range it will create, so only the startingCell is given):

Public Sub ReadInPlainText(startCell As Range, Optional textfilename As Variant)

   If IsMissing(textfilename) Then textfilename = Application.GetOpenFilename("All Files (*.*), *.*", , "Select Text File to Read")
   If textfilename = "" Then Exit Sub

   Dim filelength As Long
   Dim filenumber As Integer
   filenumber = FreeFile
   filelength = filelen(textfilename)
   Dim text As String
   Dim textlines As Variant

   Open textfilename For Binary Access Read As filenumber

   text = Space(filelength)
   Get #filenumber, , text

   'split the file with vbcrlf
   textlines = Split(text, vbCrLf) 

   'output to range
   Dim outputRange As Range
   Set outputRange = startCell
   Set outputRange = outputRange.Resize(UBound(textlines), 1)
   outputRange.Value = Application.Transpose(textlines)

   Close filenumber
 End Sub

Conversely, if you need to write out a range to a text file, this does it quickly in one print statement (note: the file 'Open' type here is in text mode, not binary..unlike the read routine above).

Public Sub WriteRangeAsPlainText(ExportRange As Range, Optional textfilename As Variant)
   If IsMissing(textfilename) Then textfilename = Application.GetSaveAsFilename(FileFilter:="Text Files (*.txt), *.txt")
   If textfilename = "" Then Exit Sub

   Dim filenumber As Integer
   filenumber = FreeFile
   Open textfilename For Output As filenumber

   Dim textlines() As Variant, outputvar As Variant

   textlines = Application.Transpose(ExportRange.Value)
   outputvar = Join(textlines, vbCrLf)
   Print #filenumber, outputvar
   Close filenumber
End Sub

The method has been renamed to findById(…) returning an Optional so that you have to handle absence yourself:

Optional<Foo> result = repository.findById(…);

result.ifPresent(it -> …); // do something with the value if present
result.map(it -> …); // map the value if present
Foo foo = result.orElse(null); // if you want to continue just like before

How about just this?

org.apache.commons.io.IOUtils.toString(new URL("http://www.someurl.com/"));

What about angular-scroll, it's actively maintained and there is no dependency to jQuery..

This worked for me:

hoja_trabajo.Cells[i + 2, j + 1] = fecha.ToString("dd-MMM-yyyy").Replace(".", "");

You can do it the old fashioned way... with an SQL statement that looks something like this

ALTER TABLE table_name
    ADD CONSTRAINT fk_foreign_key_name
    FOREIGN KEY (foreign_key_name)
    REFERENCES target_table(target_key_name);

This assumes the keys already exist in the relevant table

The posted setdiff answer is nice. I just thought I'd post this related function I wrote a while back. Its usefulness is up to the reader :-).

lstype<-function(type='closure'){ 
    inlist<-ls(.GlobalEnv)
    if (type=='function') type <-'closure'
    typelist<-sapply(sapply(inlist,get),typeof)
    return(names(typelist[typelist==type]))
}

$location won't help you with external URLs, use the $window service instead:

$window.location.href = 'http://www.google.com';

Note that you could use the window object, but it is bad practice since $window is easily mockable whereas window is not.

At least write the code without the bushy tree:

#!/bin/bash

PASSED=$1

if   [ -d "${PASSED}" ]
then echo "${PASSED} is a directory";
elif [ -f "${PASSED}" ]
then echo "${PASSED} is a file";
else echo "${PASSED} is not valid";
     exit 1
fi

When I put that into a file "xx.sh" and create a file "xx sh", and run it, I get:

$ cp /dev/null "xx sh"
$ for file in . xx*; do sh "$file"; done
. is a directory
xx sh is a file
xx.sh is a file
$

Given that you are having problems, you should debug the script by adding:

ls -l "${PASSED}"

This will show you what ls thinks about the names you pass the script.

No, how you are doing it is correct.

http://www.w3.org/MarkUp/html-spec/html-spec_8.html#SEC8.2.2

One line solution without using extra int variable:

String name = "admin";
System.out.println((int)name.charAt(0));

passing api key in parameters makes it difficult for clients to keep their APIkeys secret, they tend to leak keys on a regular basis. A better approach is to pass it in header of request url.you can set user-key header in your code . For testing your request Url you can use Postman app in google chrome by setting user-key header to your api-key.

I recommend you to follow the android trainning post for capturing a photo. They show in an example how to take small and big pictures. You can also download the source code from here

You can use:

 Handler handler = new Handler()
 handler.postDelayed(new Runnable())

Or you can use:

 handler.removeCallbacksAndMessages(null);

Docs

public final void removeCallbacksAndMessages (Object token)

Added in API level 1 Remove any pending posts of callbacks and sent messages whose obj is token. If token is null, all callbacks and messages will be removed.

Or you could also do like the following:

Handler handler =  new Handler()
Runnable myRunnable = new Runnable() {
public void run() {
    // do something
}
};
handler.postDelayed(myRunnable,zeit_dauer2);

Then:

handler.removeCallbacks(myRunnable);

Docs

public final void removeCallbacks (Runnable r)

Added in API level 1 Remove any pending posts of Runnable r that are in the message queue.

public final void removeCallbacks (Runnable r, Object token)

Edit:

Change this:

@Override
public void onClick(View v) {
    Handler handler =  new Handler();
    Runnable myRunnable = new Runnable() {

To:

@Override
public void onClick(View v) {
    handler = new Handler();
    myRunnable = new Runnable() { /* ... */}

Because you have the below. Declared before onCreate but you re-declared and then initialized it in onClick leading to a NPE.

Handler handler; // declared before onCreate
Runnable myRunnable;

Based on previous answers

const groupBy = (prop) => (xs) =>
  xs.reduce((rv, x) =>
    Object.assign(rv, {[x[prop]]: [...(rv[x[prop]] || []), x]}), {});

and it's a little nicer to look at with object spread syntax, if your environment supports.

const groupBy = (prop) => (xs) =>
  xs.reduce((acc, x) => ({
    ...acc,
    [ x[ prop ] ]: [...( acc[ x[ prop ] ] || []), x],
  }), {});

Here, our reducer takes the partially-formed return value (starting with an empty object), and returns an object composed of the spread out members of the previous return value, along with a new member whose key is calculated from the current iteree's value at prop and whose value is a list of all values for that prop along with the current value.

Using Spring Boot (1.2.4) and Jackson (2.4.6) the following annotation based configuration worked for me.

@Configuration
public class JacksonConfiguration {

    @Bean
    public ObjectMapper objectMapper() {
        ObjectMapper mapper = new ObjectMapper();
        mapper.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false);
        mapper.configure(MapperFeature.DEFAULT_VIEW_INCLUSION, true);

        return mapper;
    }
}

Simple solution:

int str_case_ins_cmp(const char* a, const char* b) {
  int rc;

  while (1) {
    rc = tolower((unsigned char)*a) - tolower((unsigned char)*b);
    if (rc || !*a) {
      break;
    }

    ++a;
    ++b;
  }

  return rc;
}

In my case the solution was to close to restart Android Studio

I am a little bit surprised nobody mentioned

sp_help 'mytable'

an Event will fire multiple time when it is registered multiple times (even if to the same handler).

eg $("ctrl").on('click', somefunction) if this piece of code is executed every time the page is partially refreshed, the event is being registered each time too. Hence even if the ctrl is clicked only once it may execute "somefunction" multiple times - how many times it execute will depend on how many times it was registered.

this is true for any event registered in javascript.

solution:

ensure to call "on" only once.

and for some reason if you cannot control the architecture then do this:

$("ctrl").off('click'); $("ctrl").on('click', somefunction);

If you followed instructions like these:

https://getcomposer.org/doc/00-intro.md

Which tell you to do the following:

$ curl -sS https://getcomposer.org/installer | php
$ mv composer.phar /usr/local/bin/composer

Then it's likely that you, like me, ran those commands and didn't read the next part of the page telling you to stop referring to composer.phar by its full name and abbreviate it as an executable (that you just renamed with the mv command). So this:

$ php composer.phar update friendsofsymfony/elastica-bundle

Becomes this:

$ composer update friendsofsymfony/elastica-bundle

My solution for changing seconds (number) to string format (for example: 'mm:ss'):

const formattedSeconds = moment().startOf('day').seconds(S).format('mm:ss');

Write your seconds instead 'S' in example. And just use the 'formattedSeconds' where you need.

It look's like some permissions problem.

Try to set all permisions like you did in mysite1 to the others site.

By default file permissions should be 644 and dirs 755. Also check if the user that runs nginx have permission to read that files and dirs.

<?php

$string = 'foo';

if (preg_match('/[\'^£$%&*()}{@#~?><>,|=_+¬-]/', $string))
{
    // one or more of the 'special characters' found in $string
}

I'd like to give more codes to make it clear.

struct A
{
    operator bool() const { return true; }
};

struct B
{
    explicit operator bool() const { return true; }
};

int main()
{
    A a1;
    if (a1) cout << "true" << endl; // OK: A::operator bool()
    bool na1 = a1; // OK: copy-initialization selects A::operator bool()
    bool na2 = static_cast<bool>(a1); // OK: static_cast performs direct-initialization

    B b1;     
    if (b1) cout << "true" << endl; // OK: B::operator bool()
    // bool nb1 = b1; // error: copy-initialization does not consider B::operator bool()
    bool nb2 = static_cast<bool>(b1); // OK: static_cast performs direct-initialization
}

Try JSMin, got C#, Java, C and other ports and readily available too.

• Create your points using Point values of Geometry data types in MyISAM table. As of Mysql 5.7.5, InnoDB tables now also support SPATIAL indices.

• Create a SPATIAL index on these points

• Use MBRContains() to find the values:

  SELECT  *
  FROM    table
  WHERE   MBRContains(LineFromText(CONCAT(
          '('
          , @lon + 10 / ( 111.1 / cos(RADIANS(@lon)))
          , ' '
          , @lat + 10 / 111.1
          , ','
          , @lon - 10 / ( 111.1 / cos(RADIANS(@lat)))
          , ' '
          , @lat - 10 / 111.1 
          , ')' )
          ,mypoint)
  

, or, in MySQL 5.1 and above:

    SELECT  *
    FROM    table
    WHERE   MBRContains
                    (
                    LineString
                            (
                            Point (
                                    @lon + 10 / ( 111.1 / COS(RADIANS(@lat))),
                                    @lat + 10 / 111.1
                                  ),
                            Point (
                                    @lon - 10 / ( 111.1 / COS(RADIANS(@lat))),
                                    @lat - 10 / 111.1
                                  ) 
                            ),
                    mypoint
                    )

This will select all points approximately within the box (@lat +/- 10 km, @lon +/- 10km).

This actually is not a box, but a spherical rectangle: latitude and longitude bound segment of the sphere. This may differ from a plain rectangle on the Franz Joseph Land, but quite close to it on most inhabited places.

• Apply additional filtering to select everything inside the circle (not the square)

• Possibly apply additional fine filtering to account for the big circle distance (for large distances)

You can do it using named-entity recognition (NER). It's fairly simple and there are out-of-the-shelf tools out there to do it, such as spaCy.

NER is an NLP task where a neural network (or other method) is trained to detect certain entities, such as names, places, dates and organizations.

Example:

Sponge Bob went to South beach, he payed a ticket of $200!
I know, Michael is a good person, he goes to McDonalds, but donates to charity at St. Louis street.

Returns:

Just be aware that this is not 100%!

Here are a little snippet for you to try out:

import spacy

phrases = ['Sponge Bob went to South beach, he payed a ticket of $200!', 'I know, Michael is a good person, he goes to McDonalds, but donates to charity at St. Louis street.']
nlp = spacy.load('en')
for phrase in phrases:
   doc = nlp(phrase)
   replaced = ""
   for token in doc:
      if token in doc.ents:
         replaced+="XXXX "
      else:
         replaced+=token.text+" "

Read more here: https://spacy.io/usage/linguistic-features#named-entities

You could, instead of replacing with XXXX, replace based on the entity type, like:

if ent.label_ == "PERSON":
   replaced += "<PERSON> "

Then:

import re, random

personames = ["Jack", "Mike", "Bob", "Dylan"]

phrase = re.replace("<PERSON>", random.choice(personames), phrase)

As we were already using jQuery for a graphical eye-candy feature we ended up using this. A code like

$(document).ready(function() {
    // any code goes here
    init();
});

did everything we wanted and cares about browser incompatibilities at its own.

This might be simplest way -

Collections.sort(listOfStudent,new Comparator<Student>(){
                     public int compare(Student s1,Student s2){
                           // Write your logic here.
                     }});

Using Java 8(lambda expression) -

listOfStudent.sort((s1, s2) -> s1.age - s2.age); 

To solve your other problem, where you need to set scrolled if the user scrolls manually, you'd have to attach a handler to the window scroll event. Generally this is a bad idea as the handler will fire a lot, a common technique is to set a timeout, like so:

var timer = 0;
$(window).scroll(function() {
  if (timer) {
    clearTimeout(timer);
  }
  timer = setTimeout(function() {
    scrolled = $(window).scrollTop();
  }, 250);
});

That its the correct code of background size :

<div class="html-mobile-background">
</div>

<style type="text/css">
html {
    /* Whatever you want */
}
.html-mobile-background {
    position: fixed;
    z-index: -1;
    top: 0;
    left: 0;
    width: 100%;
    height: 100%; /* To compensate for mobile browser address bar space */
    background: url(YOUR BACKGROUND URL HERE) no-repeat; 
 center center fixed; 
-webkit-background-size: cover;
-moz-background-size: cover;
-o-background-size: cover;
background-size: cover;
 background-size: 100% 100%
}
</style>

Example template for C++

template< class T >
T mod( T a, T b )
{
    T const r = a%b;
    return ((r!=0)&&((r^b)<0) ? r + b : r);
}

With this template, the returned remainder will be zero or have the same sign as the divisor (denominator) (the equivalent of rounding towards negative infinity), instead of the C++ behavior of the remainder being zero or having the same sign as the dividend (numerator) (the equivalent of rounding towards zero).

Add HTML inside div using JavaScript

Syntax:

element.innerHTML += "additional HTML code"

or

element.innerHTML = element.innerHTML + "additional HTML code"

Remove HTML inside div using JavaScript

elementChild.remove();

Within Crystal, you can do it by creating a formula that uses the ToNumber function. It might be a good idea to code for the possibility that the field might include non-numeric data - like so:

If NumericText ({field}) then ToNumber ({field}) else 0

Alternatively, you might find it easier to convert the field's datatype within the query used in the report.

You need to do two things:

1. Rename and re-order the factor levels before the plot
2. Rename the title of each legend to the same title

The code:

dtt$model <- factor(dtt$model, levels=c("mb", "ma", "mc"), labels=c("MBB", "MAA", "MCC"))

library(ggplot2)
ggplot(dtt, aes(x=year, y=V, group = model, colour = model, ymin = lower, ymax = upper)) +
  geom_ribbon(alpha = 0.35, linetype=0)+ 
  geom_line(aes(linetype=model), size = 1) +       
  geom_point(aes(shape=model), size=4)  +      
  theme(legend.position=c(.6,0.8)) +
  theme(legend.background = element_rect(colour = 'black', fill = 'grey90', size = 1, linetype='solid')) +
  scale_linetype_discrete("Model 1") +
  scale_shape_discrete("Model 1") +
  scale_colour_discrete("Model 1")

However, I think this is really ugly as well as difficult to interpret. It's far better to use facets:

ggplot(dtt, aes(x=year, y=V, group = model, colour = model, ymin = lower, ymax = upper)) +
  geom_ribbon(alpha=0.2, colour=NA)+ 
  geom_line() +       
  geom_point()  +      
  facet_wrap(~model)

Connecting to Oracle is ugly. Here is some cleaner code with a using statement. A lot of the other samples don't call the IDisposable Methods on the objects they create.

using (OracleConnection connection = new OracleConnection("ConnectionString"))
    using (OracleCommand command = new OracleCommand("ProcName", connection))             
    {
          command.CommandType = CommandType.StoredProcedure;
          command.Parameters.Add("ParameterName", OracleDbType.Varchar2).Value = "Your Data Here";
          command.Parameters.Add("SomeOutVar", OracleDbType.Varchar2, 120);
          command.Parameters["return_out"].Direction = ParameterDirection.Output;
          command.Parameters.Add("SomeOutVar1", OracleDbType.Varchar2, 120);
          command.Parameters["return_out2"].Direction = ParameterDirection.Output;
          connection.Open();
          command.ExecuteNonQuery();
          string SomeOutVar = command.Parameters["SomeOutVar"].Value.ToString();
          string SomeOutVar1 = command.Parameters["SomeOutVar1"].Value.ToString();
    }

ArrayIndexOutOfBoundsException in simple words is -> you have 10 students in your class (int array size 10) and you want to view the value of the 11th student (a student who does not exist)

if you make this int i[3] then i takes values i[0] i[1] i[2]

for your problem try this code structure

double[] array = new double[50];

    for (int i = 0; i < 24; i++) {

    }

    for (int j = 25; j < 50; j++) {

    }

CSV is a Comma Seperated File. Generally the delimiter is a comma, but I have seen many other characters used as delimiters. They are just not as frequently used.

As for advising you on what to use, we need to know your application. Is the file specific to your application/program, or does this need to work with other programs?

You can use the instanceof operator to test to see if it is a double prior to casting. You can then safely cast it to a double. In addition you can test it against other known types (e.g. Integer) and then coerce them into a double manually if desired.

    Double d = null;
    if (obj instanceof Double) {
        d = (Double) obj;
    }

In Addition to @Yifei answer. If you have special character like @, &, $

You have to go with percent-encode | encode the special characters. E.g. instead of this:

http://foo:B@[email protected]:80

you write this:

http://foo:B%[email protected]:80

So @ gets replaced with %40.

you need to place the opening brace after main , not before it

#include <stdio.h>
#include <stdlib.h>
#include <time.h>

int main(void)
{

A combination of some of the answers:

var d = new Date(date);
date = [
  d.getFullYear(),
  ('0' + (d.getMonth() + 1)).slice(-2),
  ('0' + d.getDate()).slice(-2)
].join('-');

var result = from sc in enumerableOfSomeClass
             join soc in enumerableOfSomeOtherClass
             on sc.Property1 equals soc.Property2
             select new { SomeClass = sc, SomeOtherClass = soc };

Would be equivalent to:

var result = enumerableOfSomeClass
    .Join(enumerableOfSomeOtherClass,
          sc => sc.Property1,
          soc => soc.Property2,
          (sc, soc) => new
                       {
                           SomeClass = sc,
                           SomeOtherClass = soc
                       });

As you can see, when it comes to joins, query syntax is usually much more readable than lambda syntax.

var myNumber: number = 1200;_x000D_
//convert to hexadecimal value_x000D_
console.log(myNumber.toString(16)); //will return  4b0_x000D_
//Other way of converting to hexadecimal_x000D_
console.log(Math.abs(myNumber).toString(16)); //will return  4b0_x000D_
//convert to decimal value_x000D_
console.log(parseFloat(myNumber.toString()).toFixed(2)); //will return  1200.00

Use an extension on String

Swift 3

extension String {
    func height(withConstrainedWidth width: CGFloat, font: UIFont) -> CGFloat {
        let constraintRect = CGSize(width: width, height: .greatestFiniteMagnitude)
        let boundingBox = self.boundingRect(with: constraintRect, options: .usesLineFragmentOrigin, attributes: [NSFontAttributeName: font], context: nil)
    
        return ceil(boundingBox.height)
    }

    func width(withConstrainedHeight height: CGFloat, font: UIFont) -> CGFloat {
        let constraintRect = CGSize(width: .greatestFiniteMagnitude, height: height)
        let boundingBox = self.boundingRect(with: constraintRect, options: .usesLineFragmentOrigin, attributes: [NSFontAttributeName: font], context: nil)

        return ceil(boundingBox.width)
    }
}

and also on NSAttributedString (which is very useful at times)

extension NSAttributedString {
    func height(withConstrainedWidth width: CGFloat) -> CGFloat {
        let constraintRect = CGSize(width: width, height: .greatestFiniteMagnitude)
        let boundingBox = boundingRect(with: constraintRect, options: .usesLineFragmentOrigin, context: nil)
    
        return ceil(boundingBox.height)
    }

    func width(withConstrainedHeight height: CGFloat) -> CGFloat {
        let constraintRect = CGSize(width: .greatestFiniteMagnitude, height: height)
        let boundingBox = boundingRect(with: constraintRect, options: .usesLineFragmentOrigin, context: nil)
    
        return ceil(boundingBox.width)
    }
}

Swift 4 & 5

Just change the value for attributes in the extension String methods

from

[NSFontAttributeName: font]

to

[.font : font]

why not both to be sure?

if(opener.document){
  $("#testdiv",opener.document).doStuff();
}else{
  $("#testdiv",window.opener).doStuff();
}

To use C# (C# Script was initialized at 2015) on ASPX page you can make use the following syntax.

Start Tag:- <% End tag:- %> Please make sure that all the C# code must reside inside this <%%> .

Syntax Example:-

• <%@ Import Namespace="System.Web.UI.WebControls" %> (For importing Namespace) Reference to some basic namespaces for working with ASPX page.

  <%@ Import Namespace="System.Web.UI.WebControls" %> <%@ Import Namespace="System.Diagnostics" %> <%@ Import Namespace="System" %> <%@ Import Namespace="System.Web" %> <%@ Import Namespace="System.Web.UI" %> <%@ Import Namespace="System.IO" %>

C# Code:-

`<%
if (Session["New"] != null)
{
    Page.Title = ActionController.GetName(Session["New"].ToString());
}
%>`

Features of C# Script:

• No need of compilation. Run time execution is occurred like Java Script.

Before using C# script make sure the following things:-

• You are on WebForm. Not on WebForm with master page.
• If you are in WebForm with master page make sure that you have written your C# script at Master page file.

• C# script can be inserted anywhere in the aspx page but after the page meta declaration like

  <%@ Master Language="C#" AutoEventWireup="true" CodeBehind="Profile.master.cs" Inherits="OOSDDemo.Profile" %>

  <%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm1.aspx.cs" Inherits="WebApplication3.WebForm1" %> (For WebForm)

One of the first things that you should check is that the SQL Server (MSSQLSERVER) is started. You can go to the Services Console (services.msc) and look for SQL Server (MSSQLSERVER) to see that it is started. If not, then start the service.

You could also do this through an elevated command prompt by typing net start mssqlserver.

you just have to add following code in alert dialog box on save click

          recyclerData.add(position, updateText.getText().toString());
          recyclerAdapter.notifyItemChanged(position);

For me it was the

article:modified_time

in the page source.

Thanks from all, Load the Scripts in specific pages that you use, not for all pages, sometimes using swiper.js or other library it may cause this error message, the only way to solve this issue it to load the JS library on specific pages that ID is exist and prevent loading of the same library in all pages.

Hope this help you.

In simple words (mainly for newbie in coding), we can say,

    `return`: exits the function,
    `exit()`: exits the program (called as process while running)

Also if you observed, this is very basic, but...,

    `return`: is the keyword
    `exit()`: is the function

    .then(data => console.log(`Done: `, data), err => console.log(`Error: `, err))
 
setTimeout(()=> chain.cancel(), 1000); // abort the request after 1000ms 

You can make it wait using $RANDOM, a default random number generator. In the below I am using 240 seconds. Hope that helps @

if you're using yarn:

1. delete yarn.lock
2. run yarn

I tried the following and presto changeo, my transparent window was no longer frozen in place but could be moved!! (throw away all those other complex solutions above...)

   private void Window_MouseLeftButtonDown(object sender, MouseButtonEventArgs e)
    {
        base.OnMouseLeftButtonDown(e);
        // Begin dragging the window
        this.DragMove();
    }

According to the error message, you declared myLoc as a pointer to an NSInteger (NSInteger *myLoc) rather than an actual NSInteger (NSInteger myLoc). It needs to be the latter.

On top of what @wisekiddo said, you can also modify your build settings in the project.pbxproj file by setting the Swift 3 @obj Inference to default like SWIFT_SWIFT3_OBJC_INFERENCE = Default; for your build flavors (i.e. debug and release), especially if you're coming from some other environment besides Xcode

In simple word "you can't do it through simple setListAdapter" . you must used custom listview for freely changes in text color or in any other views

for Custom Listview you can go with this link

import operator
sortedlist = sorted(reader, key=operator.itemgetter(3), reverse=True)

or use lambda

sortedlist = sorted(reader, key=lambda row: row[3], reverse=True)

select min (salary) from Employee where Salary in (Select Top 3 Salary from Employee order by Salary desc)

Freddy's answer helped me a lot to get this working. For the sake of completeness here's how you could implement hashing of the token:

private string ComputeHash(Guid input)
{
    byte[] source = input.ToByteArray();

    var encoder = new SHA256Managed();
    byte[] encoded = encoder.ComputeHash(source);

    return Convert.ToBase64String(encoded);
}

In CreateAsync:

var guid = Guid.NewGuid();
...
_refreshTokens.TryAdd(ComputeHash(guid), refreshTokenTicket);
context.SetToken(guid.ToString());

ReceiveAsync:

public async Task ReceiveAsync(AuthenticationTokenReceiveContext context)
{
    Guid token;

    if (Guid.TryParse(context.Token, out token))
    {
        AuthenticationTicket ticket;

        if (_refreshTokens.TryRemove(ComputeHash(token), out ticket))
        {
            context.SetTicket(ticket);
        }
    }
}

This kind of thing doesn't just magically happen on its own; you changed something! In industry we use version control to make regular savepoints, so when something goes wrong we can trace back the specific changes we made that resulted in that problem.

Since you haven't done that here, we can only really guess. In Visual Studio, Intellisense (the technology that gives you auto-complete dropdowns and those squiggly red lines) works separately from the actual C++ compiler under the bonnet, and sometimes gets things a bit wrong.

In this case I'd ask why you're including both cstdlib and stdlib.h; you should only use one of them, and I recommend the former. They are basically the same header, a C header, but cstdlib puts them in the namespace std in order to "C++-ise" them. In theory, including both wouldn't conflict but, well, this is Microsoft we're talking about. Their C++ toolchain sometimes leaves something to be desired. Any time the Intellisense disagrees with the compiler has to be considered a bug, whichever way you look at it!

Anyway, your use of using namespace std (which I would recommend against, in future) means that std::system from cstdlib now conflicts with system from stdlib.h. I can't explain what's going on with std::cout and std::cin.

Try removing #include <stdlib.h> and see what happens.

If your program is building successfully then you don't need to worry too much about this, but I can imagine the false positives being annoying when you're working in your IDE.

bind -p will show a list of bound escaped keys in your shell, that might help giving you more ideas / search terms.

Based on Haim's answer here's a simplified example if you're looking to compare values that exist in BOTH tables, otherwise if there's a row in one table but not the other it will also return it....

Took me a couple of hours to figure out. Here's a fully tested simply query for comparing "tbl_a" and "tbl_b"

SELECT ID, col
FROM
(
    SELECT
    tbl_a.ID, tbl_a.col FROM tbl_a
    UNION ALL
    SELECT
    tbl_b.ID, tbl_b.col FROM tbl_b
) t
WHERE ID IN (select ID from tbl_a) AND ID IN (select ID from tbl_b)
GROUP BY
ID, col
HAVING COUNT(*) = 1
 ORDER BY ID

So you need to add the extra "where in" clause:

WHERE ID IN (select ID from tbl_a) AND ID IN (select ID from tbl_b)

Also:

For ease of reading if you want to indicate the table names you can use the following:

SELECT tbl, ID, col
FROM
(
    SELECT
    tbl_a.ID, tbl_a.col, "name_to_display1" as "tbl" FROM tbl_a
    UNION ALL
    SELECT
    tbl_b.ID, tbl_b.col, "name_to_display2" as "tbl" FROM tbl_b
) t
WHERE ID IN (select ID from tbl_a) AND ID IN (select ID from tbl_b)
GROUP BY
ID, col
HAVING COUNT(*) = 1
 ORDER BY ID

If you are using getActivity() then you have to make sure that the calling activity is added already. If activity has not been added in such case so you may get null when you call getActivity()

in such cases getContext() is safe

then the code for starting the activity will be slightly changed like,

Intent intent = new Intent(getContext(), mFragmentFavorite.class);
startActivity(intent);

Activity, Service and Application extends ContextWrapper class so you can use this or getContext() or getApplicationContext() in the place of first argument.

In case your index exports a module - That module should not import its components from the same index, it should import them directly from the components file.

I had this issue, and when I changed from importing the components in the module file using the index to importing them using the direct file, this resolved.

e.g changed:

import { NgModule } from '@angular/core';
import { MainNavComponent } from './index';
@NgModule({
  imports: [],
  exports: [MainNavComponent],
  declarations: [ MainNavComponent ],
  bootstrap:    [ MainNavComponent ]
})
export class MainNavModule {}

to:

import { NgModule } from '@angular/core';
import { MainNavComponent } from './MainNavComponent';
@NgModule({
  imports: [],
  exports: [MainNavComponent],
  declarations: [ MainNavComponent ],
  bootstrap:    [ MainNavComponent ]
})
export class MainNavModule {}

also remove the now unnecessary exports from you index, e.g:

export { MainNavModule } from './MainNavModule';
export { MainNavComponent } from './MainNavComponent';

to:

export { MainNavModule } from './MainNavModule';

This function converts a Blob into a File and it works great for me.

Vanilla JavaScript

function blobToFile(theBlob, fileName){
    //A Blob() is almost a File() - it's just missing the two properties below which we will add
    theBlob.lastModifiedDate = new Date();
    theBlob.name = fileName;
    return theBlob;
}

TypeScript (with proper typings)

public blobToFile = (theBlob: Blob, fileName:string): File => {
    var b: any = theBlob;
    //A Blob() is almost a File() - it's just missing the two properties below which we will add
    b.lastModifiedDate = new Date();
    b.name = fileName;

    //Cast to a File() type
    return <File>theBlob;
}

Usage

var myBlob = new Blob();

//do stuff here to give the blob some data...

var myFile = blobToFile(myBlob, "my-image.png");

I realize you've found another answer - but the fact is that your original code was nearly correct but for a syntax error.

Your code contained the line

set /A COUNTER=%COUNTER%+1

and the syntax that would work is simply...

set /A COUNTER=COUNTER+1

See http://ss64.com/nt/set.html for all the details on the SET command. I just thought I'd add this clarification for anyone else who doesn't have the option of using FreeDOS.

OP's question is about plain JavaScript and not jQuery. Although there are plenty of answers and I like @Pawan Nogariya answer, please check this alternative out.

You can use XPATH in JavaScript. More info on the MDN article here.

The document.evaluate() method evaluates an XPATH query/expression. So you can pass XPATH expressions there, traverse into the HTML document and locate the desired element.

In XPATH you can select an element, by the text node like the following, whch gets the div that has the following text node.

//div[text()="Hello World"]

To get an element that contains some text use the following:

//div[contains(., 'Hello')]

The contains() method in XPATH takes a node as first parameter and the text to search for as second parameter.

Check this plunk here, this is an example use of XPATH in JavaScript

Here is a code snippet:

var headings = document.evaluate("//h1[contains(., 'Hello')]", document, null, XPathResult.ANY_TYPE, null );
var thisHeading = headings.iterateNext();

console.log(thisHeading); // Prints the html element in console
console.log(thisHeading.textContent); // prints the text content in console

thisHeading.innerHTML += "<br />Modified contents";  

As you can see, I can grab the HTML element and modify it as I like.

Here I have used omit() for the respective 'key' which you want to remove... by using the Lodash library:

var credentials = [{
        fname: "xyz",
        lname: "abc",
        age: 23
}]

let result = _.map(credentials, object => {
                       return _.omit(object, ['fname', 'lname'])
                   })

console.log('result', result)

Guys I found the issue

I just tried by adding the qualifier name in employee service finally it solved my issue.

@Service("employeeService")

public class EmployeeServiceImpl implements EmployeeService{

}

Or you can tell javascript where to write it.

<script type="text/javascript">
    var elem = document.getElementById('myDiv');
    var msg= 'Hello<br />';
    elem.innerHTML = msg;
</script>

You can combine this with other functions to have function write content after being evaluated.

Enter the following into the result cell and then press Ctrl & Shift while pushing ENTER:

=MIN(If(A1:E1>0,A1:E1))

here is the simple example :

select <duplicate_column_name> from <table_name> group by <duplicate_column_name> having count(*)>=2

It will definitly work. :)

Native browser smooth scrolling in JavaScript is like this:

// scroll to specific values,
// same as window.scroll() method.
// for scrolling a particular distance, use window.scrollBy().
window.scroll({
  top: 2500, 
  left: 0, 
  behavior: 'smooth' 
});

// scroll certain amounts from current position 
window.scrollBy({ 
  top: 100, // negative value acceptable
  left: 0, 
  behavior: 'smooth' 
});

// scroll to a certain element
document.querySelector('.hello').scrollIntoView({ 
  behavior: 'smooth' 
});

Look at the r.status_code attribute:

if r.status_code == 404:
    # A 404 was issued.

Demo:

>>> import requests
>>> r = requests.get('http://httpbin.org/status/404')
>>> r.status_code
404

If you want requests to raise an exception for error codes (4xx or 5xx), call r.raise_for_status():

>>> r = requests.get('http://httpbin.org/status/404')
>>> r.raise_for_status()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "requests/models.py", line 664, in raise_for_status
    raise http_error
requests.exceptions.HTTPError: 404 Client Error: NOT FOUND
>>> r = requests.get('http://httpbin.org/status/200')
>>> r.raise_for_status()
>>> # no exception raised.

You can also test the response object in a boolean context; if the status code is not an error code (4xx or 5xx), it is considered ‘true’:

if r:
    # successful response

If you want to be more explicit, use if r.ok:.

You need to include the library path (-L/usr/local/lib/)

gcc -o Opentest Opentest.c -L/usr/local/lib/ -lssl -lcrypto

It works for me.

Use empty(). It checks for both empty strings and null.

if (!empty($_POST['user'])) {
  // do stuff
}

From the manual:

The following things are considered to be empty:

"" (an empty string)  
0 (0 as an integer)  
0.0 (0 as a float)  
"0" (0 as a string)    
NULL  
FALSE  
array() (an empty array)  
var $var; (a variable declared, but without a value in a class)  

If you aren't dynamically loading scripts or marking them as defer or async, then scripts are loaded in the order encountered in the page. It doesn't matter whether it's an external script or an inline script - they are executed in the order they are encountered in the page. Inline scripts that come after external scripts are held until all external scripts that came before them have loaded and run.

Async scripts (regardless of how they are specified as async) load and run in an unpredictable order. The browser loads them in parallel and it is free to run them in whatever order it wants.

There is no predictable order among multiple async things. If one needed a predictable order, then it would have to be coded in by registering for load notifications from the async scripts and manually sequencing javascript calls when the appropriate things are loaded.

When a script tag is inserted dynamically, how the execution order behaves will depend upon the browser. You can see how Firefox behaves in this reference article. In a nutshell, the newer versions of Firefox default a dynamically added script tag to async unless the script tag has been set otherwise.

A script tag with async may be run as soon as it is loaded. In fact, the browser may pause the parser from whatever else it was doing and run that script. So, it really can run at almost any time. If the script was cached, it might run almost immediately. If the script takes awhile to load, it might run after the parser is done. The one thing to remember with async is that it can run anytime and that time is not predictable.

A script tag with defer waits until the entire parser is done and then runs all scripts marked with defer in the order they were encountered. This allows you to mark several scripts that depend upon one another as defer. They will all get postponed until after the document parser is done, but they will execute in the order they were encountered preserving their dependencies. I think of defer like the scripts are dropped into a queue that will be processed after the parser is done. Technically, the browser may be downloading the scripts in the background at any time, but they won't execute or block the parser until after the parser is done parsing the page and parsing and running any inline scripts that are not marked defer or async.

Here's a quote from that article:

script-inserted scripts execute asynchronously in IE and WebKit, but synchronously in Opera and pre-4.0 Firefox.

The relevant part of the HTML5 spec (for newer compliant browsers) is here. There is a lot written in there about async behavior. Obviously, this spec doesn't apply to older browsers (or mal-conforming browsers) whose behavior you would probably have to test to determine.

A quote from the HTML5 spec:

Then, the first of the following options that describes the situation must be followed:

If the element has a src attribute, and the element has a defer attribute, and the element has been flagged as "parser-inserted", and the element does not have an async attribute The element must be added to the end of the list of scripts that will execute when the document has finished parsing associated with the Document of the parser that created the element.

The task that the networking task source places on the task queue once the fetching algorithm has completed must set the element's "ready to be parser-executed" flag. The parser will handle executing the script.

If the element has a src attribute, and the element has been flagged as "parser-inserted", and the element does not have an async attribute The element is the pending parsing-blocking script of the Document of the parser that created the element. (There can only be one such script per Document at a time.)

The task that the networking task source places on the task queue once the fetching algorithm has completed must set the element's "ready to be parser-executed" flag. The parser will handle executing the script.

If the element does not have a src attribute, and the element has been flagged as "parser-inserted", and the Document of the HTML parser or XML parser that created the script element has a style sheet that is blocking scripts The element is the pending parsing-blocking script of the Document of the parser that created the element. (There can only be one such script per Document at a time.)

Set the element's "ready to be parser-executed" flag. The parser will handle executing the script.

If the element has a src attribute, does not have an async attribute, and does not have the "force-async" flag set The element must be added to the end of the list of scripts that will execute in order as soon as possible associated with the Document of the script element at the time the prepare a script algorithm started.

The task that the networking task source places on the task queue once the fetching algorithm has completed must run the following steps:

If the element is not now the first element in the list of scripts that will execute in order as soon as possible to which it was added above, then mark the element as ready but abort these steps without executing the script yet.

Execution: Execute the script block corresponding to the first script element in this list of scripts that will execute in order as soon as possible.

Remove the first element from this list of scripts that will execute in order as soon as possible.

If this list of scripts that will execute in order as soon as possible is still not empty and the first entry has already been marked as ready, then jump back to the step labeled execution.

If the element has a src attribute The element must be added to the set of scripts that will execute as soon as possible of the Document of the script element at the time the prepare a script algorithm started.

The task that the networking task source places on the task queue once the fetching algorithm has completed must execute the script block and then remove the element from the set of scripts that will execute as soon as possible.

Otherwise The user agent must immediately execute the script block, even if other scripts are already executing.

What about Javascript module scripts, type="module"?

Javascript now has support for module loading with syntax like this:

<script type="module">
  import {addTextToBody} from './utils.mjs';

  addTextToBody('Modules are pretty cool.');
</script>

Or, with src attribute:

<script type="module" src="http://somedomain.com/somescript.mjs">
</script>

All scripts with type="module" are automatically given the defer attribute. This downloads them in parallel (if not inline) with other loading of the page and then runs them in order, but after the parser is done.

Module scripts can also be given the async attribute which will run inline module scripts as soon as possible, not waiting until the parser is done and not waiting to run the async script in any particular order relative to other scripts.

There's a pretty useful timeline chart that shows fetch and execution of different combinations of scripts, including module scripts here in this article: Javascript Module Loading.

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

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

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

Just do System.out.println(e.getActionCommand()); inside actionPerformed(ActionEvent e) function. This will tell you which command is just performed.

or

if(e.getActionCommand().equals("Add")){

   System.out.println("Add button pressed");
}

Just add one more block to Ozzy's code so the thing looks like this:

public static Dimension getScaledDimension(Dimension imgSize,Dimension boundary) {

    int original_width = imgSize.width;
    int original_height = imgSize.height;
    int bound_width = boundary.width;
    int bound_height = boundary.height;
    int new_width = original_width;
    int new_height = original_height;

    // first check if we need to scale width
    if (original_width > bound_width) {
        //scale width to fit
        new_width = bound_width;
        //scale height to maintain aspect ratio
        new_height = (new_width * original_height) / original_width;
    }

    // then check if we need to scale even with the new height
    if (new_height > bound_height) {
        //scale height to fit instead
        new_height = bound_height;
        //scale width to maintain aspect ratio
        new_width = (new_height * original_width) / original_height;
    }
    // upscale if original is smaller
    if (original_width < bound_width) {
        //scale width to fit
        new_width = bound_width;
        //scale height to maintain aspect ratio
        new_height = (new_width * original_height) / original_width;
    }

    return new Dimension(new_width, new_height);
}

adding muted="muted" property to HTML5 tag solved my issue

This is a two part question:

How to iterate over the entries of a Map - @ScArcher2 has answered that perfectly.

What is the order of iteration - if you are just using Map, then strictly speaking, there are no ordering guarantees. So you shouldn't really rely on the ordering given by any implementation. However, the SortedMap interface extends Map and provides exactly what you are looking for - implementations will aways give a consistent sort order.

NavigableMap is another useful extension - this is a SortedMap with additional methods for finding entries by their ordered position in the key set. So potentially this can remove the need for iterating in the first place - you might be able to find the specific entry you are after using the higherEntry, lowerEntry, ceilingEntry, or floorEntry methods. The descendingMap method even gives you an explicit method of reversing the traversal order.

Eureka!

xy.list <- as.list(as.data.frame(t(xy.df)))

/Images/myImage.png

this has to be in root of your domain/subdomain

http://website.to/Images/myImage.png

and it will work

However, I think it would work like this, too

• images
  • yourimage.png
• styles
  • style.css

style.css:

body{
    background: url(../images/yourimage.png);
}

According to the documentation there are several ways to do the inlining.
The right way you must choose based on the situation.

1) Simply put the variable from server to javascript :

<script th:inline="javascript">
/*<![CDATA[*/

var message = [[${message}]];
alert(message);

/*]]>*/
</script>

2) Combine javascript variables with server side variables, e.g. you need to create link for requesting inside the javascript:

<script th:inline="javascript">
        /*<![CDATA[*/
        function sampleGetByJquery(v) {
            /*[+
            var url = [[@{/my/get/url(var1=${#httpServletRequest.getParameter('var1')})}]] 
                      + "&var2="+v;
             +]*/
            $("#myPanel").load(url, function() {});
        }
        /*]]>*/
        </script>

The one situation I can't resolve - then I need to pass javascript variable inside the Java method calling inside the template (it's impossible I guess).

It has been three years since this question was asked, but I am just now coming across it. Since this answer is so far down the stack, please allow me to repeat it:

Q: I am interested if there are any limits to what types of values can be set using const in JavaScript—in particular functions. Is this valid? Granted it does work, but is it considered bad practice for any reason?

I was motivated to do some research after observing one prolific JavaScript coder who always uses const statement for functions, even when there is no apparent reason/benefit.

In answer to "is it considered bad practice for any reason?" let me say, IMO, yes it is, or at least, there are advantages to using function statement.

It seems to me that this is largely a matter of preference and style. There are some good arguments presented above, but none so clear as is done in this article:

Constant confusion: why I still use JavaScript function statements by medium.freecodecamp.org/Bill Sourour, JavaScript guru, consultant, and teacher.

I urge everyone to read that article, even if you have already made a decision.

Here's are the main points:

Function statements have two clear advantages over [const] function expressions:

Advantage #1: Clarity of intent

When scanning through thousands of lines of code a day, it’s useful to be able to figure out the programmer’s intent as quickly and easily as possible.

Advantage #2: Order of declaration == order of execution

Ideally, I want to declare my code more or less in the order that I expect it will get executed.

This is the showstopper for me: any value declared using the const keyword is inaccessible until execution reaches it.

What I’ve just described above forces us to write code that looks upside down. We have to start with the lowest level function and work our way up.

My brain doesn’t work that way. I want the context before the details.

Most code is written by humans. So it makes sense that most people’s order of understanding roughly follows most code’s order of execution.

Regarding client timeouts and the use of XACT_ABORT to handle them, in my opinion there is at least one very good reason to have timeouts in client APIs like SqlClient, and that is to guard the client application code from deadlocks occurring in SQL server code. In this case the client code has no fault, but has to protect it self from blocking forever waiting for the command to complete on the server. So conversely, if client timeouts have to exist to protect client code, so does XACT_ABORT ON has to protect server code from client aborts, in case the server code takes longer to execute than the client is willing to wait for.

Maybe you have a file/directory named test in the directory. If this directory exists, and has no dependencies that are more recent, then this target is not rebuild.

To force rebuild on these kind of not-file-related targets, you should make them phony as follows:

.PHONY: all test clean

Note that you can declare all of your phony targets there.

A phony target is one that is not really the name of a file; rather it is just a name for a recipe to be executed when you make an explicit request.

I strongly suspect that's because of the network connection or the web server you're talking to - it's not BufferedReader's fault. Try measuring this:

InputStream stream = conn.getInputStream();
byte[] buffer = new byte[1000];
// Start timing
while (stream.read(buffer) > 0)
{
}
// End timing

I think you'll find it's almost exactly the same time as when you're parsing the text.

Note that you should also give InputStreamReader an appropriate encoding - the platform default encoding is almost certainly not what you should be using.

Actually, curl has an option explicitly for this: --resolve

Instead of curl -H 'Host: yada.com' http://127.0.0.1/something

use curl --resolve 'yada.com:80:127.0.0.1' http://yada.com/something

What's the difference, you ask?

Among others, this works with HTTPS. Assuming your local server has a certificate for yada.com, the first example above will fail because the yada.com certificate doesn't match the 127.0.0.1 hostname in the URL.

The second example works correctly with HTTPS.

In essence, passing a "Host" header via -H does hack your Host into the header set, but bypasses all of curl's host-specific intelligence. Using --resolve leverages all of the normal logic that applies, but simply pretends the DNS lookup returned the data in your command-line option. It works just like /etc/hosts should.

Note --resolve takes a port number, so for HTTPS you would use

curl --resolve 'yada.com:443:127.0.0.1' https://yada.com/something

The right way to add further configurations to the Spring Boot peconfigured ObjectMapper is to define a Jackson2ObjectMapperBuilderCustomizer. Else you are overwriting Springs configuration, which you do not want to lose.

 @Configuration
public class MyJacksonConfigurer implements Jackson2ObjectMapperBuilderCustomizer {
    @Override
    public void customize(Jackson2ObjectMapperBuilder builder) {
        builder.deserializerByType(LocalDate.class, new MyOwnJsonLocalDateTimeDeserializer());
    }
}

You can also add -oHostKeyAlgorithms=+ssh-dss in your ssh line:

ssh -oHostKeyAlgorithms=+ssh-dss user@host

For Ubuntu 20.04

After trying many solution

sudo apt install adb

worked for me.

After installing try command adb devices for starting daemon successfully then again use same command adb devices to get the list of devices

According to the json.org specification, your return is invalid. The names are always quoted, so you should be returning

{ "title": "One", "key": "1" }

and

[ { "title": "One", "key": "1" }, { "title": "Two", "key": "2" } ]

This may not be the problem with your setup, since you say one of them works now, but it should be fixed for correctness in case you need to switch to another JSON parser in the future.

The other answers set the timezone for all dates in your system. This doesn't always work well if you want to support multiple timezones for your users.

Here's the short version:

<?php
$date = new DateTime("now", new DateTimeZone('America/New_York') );
echo $date->format('Y-m-d H:i:s');

Works in PHP >= 5.2.0

List of supported timezones: php.net/manual/en/timezones.php

Here's a version with an existing time and setting timezone by a user setting

<?php

$usersTimezone = 'America/New_York';
$date = new DateTime( 'Thu, 31 Mar 2011 02:05:59 GMT', new DateTimeZone($usersTimezone) );
echo $date->format('Y-m-d H:i:s');

Here is a more verbose version to show the process a little more clearly

<?php

// Date for a specific date/time:
$date = new DateTime('Thu, 31 Mar 2011 02:05:59 GMT');

// Output date (as-is)
echo $date->format('l, F j Y g:i:s A');     

// Output line break (for testing)
echo "\n<br />\n";

// Example user timezone (to show it can be used dynamically)
$usersTimezone = 'America/New_York';

// Convert timezone
$tz = new DateTimeZone($usersTimezone);
$date->setTimeZone($tz);

// Output date after 
echo $date->format('l, F j Y g:i:s A');

Libraries

• Carbon — A very popular date library.
• Chronos — A drop-in replacement for Carbon focused on immutability. See below on why that's important.
• jenssegers/date — An extension of Carbon that adds multi-language support.

I'm sure there are a number of other libraries available, but these are a few I'm familiar with.

Bonus Lesson: Immutable Date Objects

While you're here, let me save you some future headache. Let's say you want to calculate 1 week from today and 2 weeks from today. You might write some code like:

<?php

// Create a datetime (now, in this case 2017-Feb-11)
$today = new DateTime();

echo $today->format('Y-m-d') . "\n<br>";
echo "---\n<br>";

$oneWeekFromToday = $today->add(DateInterval::createFromDateString('7 days'));
$twoWeeksFromToday = $today->add(DateInterval::createFromDateString('14 days'));

echo $today->format('Y-m-d') . "\n<br>";
echo $oneWeekFromToday->format('Y-m-d') . "\n<br>";
echo $twoWeeksFromToday->format('Y-m-d') . "\n<br>";
echo "\n<br>";

The output:

2017-02-11 
--- 
2017-03-04 
2017-03-04 
2017-03-04

Hmmmm... That's not quite what we wanted. Modifying a traditional DateTime object in PHP not only returns the updated date but modifies the original object as well.

This is where DateTimeImmutable comes in.

$today = new DateTimeImmutable();

echo $today->format('Y-m-d') . "\n<br>";
echo "---\n<br>";

$oneWeekFromToday = $today->add(DateInterval::createFromDateString('7 days'));
$twoWeeksFromToday = $today->add(DateInterval::createFromDateString('14 days'));

echo $today->format('Y-m-d') . "\n<br>";
echo $oneWeekFromToday->format('Y-m-d') . "\n<br>";
echo $twoWeeksFromToday->format('Y-m-d') . "\n<br>";

The output:

2017-02-11 
--- 
2017-02-11 
2017-02-18 
2017-02-25 

In this second example, we get the dates we expected back. By using DateTimeImmutable instead of DateTime, we prevent accidental state mutations and prevent potential bugs.

Front :

  <Image Name="camImage"/>

Back:

 public async void Base64ToImage(string base64String)
        {
            // read stream
            var bytes = Convert.FromBase64String(base64String);
            var image = bytes.AsBuffer().AsStream().AsRandomAccessStream();

            // decode image
            var decoder = await BitmapDecoder.CreateAsync(image);
            image.Seek(0);

            // create bitmap
            var output = new WriteableBitmap((int)decoder.PixelHeight, (int)decoder.PixelWidth);
            await output.SetSourceAsync(image);

            camImage.Source = output;
        }

If using SASS and Bootstrap 4, you can change the alternating background row color for both .table and .table-dark with:

$table-accent-bg: #990000;
$table-dark-accent-bg: #990000;

No, you can't undo, rollback or reverse a commit.

STOP THE DATABASE!

(Note: if you deleted the data directory off the filesystem, do NOT stop the database. The following advice applies to an accidental commit of a DELETE or similar, not an rm -rf /data/directory scenario).

If this data was important, STOP YOUR DATABASE NOW and do not restart it. Use pg_ctl stop -m immediate so that no checkpoint is run on shutdown.

You cannot roll back a transaction once it has commited. You will need to restore the data from backups, or use point-in-time recovery, which must have been set up before the accident happened.

If you didn't have any PITR / WAL archiving set up and don't have backups, you're in real trouble.

Urgent mitigation

Once your database is stopped, you should make a file system level copy of the whole data directory - the folder that contains base, pg_clog, etc. Copy all of it to a new location. Do not do anything to the copy in the new location, it is your only hope of recovering your data if you do not have backups. Make another copy on some removable storage if you can, and then unplug that storage from the computer. Remember, you need absolutely every part of the data directory, including pg_xlog etc. No part is unimportant.

Exactly how to make the copy depends on which operating system you're running. Where the data dir is depends on which OS you're running and how you installed PostgreSQL.

Ways some data could've survived

If you stop your DB quickly enough you might have a hope of recovering some data from the tables. That's because PostgreSQL uses multi-version concurrency control (MVCC) to manage concurrent access to its storage. Sometimes it will write new versions of the rows you update to the table, leaving the old ones in place but marked as "deleted". After a while autovaccum comes along and marks the rows as free space, so they can be overwritten by a later INSERT or UPDATE. Thus, the old versions of the UPDATEd rows might still be lying around, present but inaccessible.

Additionally, Pg writes in two phases. First data is written to the write-ahead log (WAL). Only once it's been written to the WAL and hit disk, it's then copied to the "heap" (the main tables), possibly overwriting old data that was there. The WAL content is copied to the main heap by the bgwriter and by periodic checkpoints. By default checkpoints happen every 5 minutes. If you manage to stop the database before a checkpoint has happened and stopped it by hard-killing it, pulling the plug on the machine, or using pg_ctl in immediate mode you might've captured the data from before the checkpoint happened, so your old data is more likely to still be in the heap.

Now that you have made a complete file-system-level copy of the data dir you can start your database back up if you really need to; the data will still be gone, but you've done what you can to give yourself some hope of maybe recovering it. Given the choice I'd probably keep the DB shut down just to be safe.

Recovery

You may now need to hire an expert in PostgreSQL's innards to assist you in a data recovery attempt. Be prepared to pay a professional for their time, possibly quite a bit of time.

I posted about this on the Pg mailing list, and ?????? ?????? linked to depesz's post on pg_dirtyread, which looks like just what you want, though it doesn't recover TOASTed data so it's of limited utility. Give it a try, if you're lucky it might work.

See: pg_dirtyread on GitHub.

I've removed what I'd written in this section as it's obsoleted by that tool.

Prevention

See my blog entry Preventing PostgreSQL database corruption.

On a semi-related side-note, if you were using two phase commit you could ROLLBACK PREPARED for a transction that was prepared for commit but not fully commited. That's about the closest you get to rolling back an already-committed transaction, and does not apply to your situation.

if you want to stay DRY, use an include.

{% if foo %}
  {% with a as b %}
    {% include "snipet.html" %}
  {% endwith %} 
{% else %}
  {% with bar as b %}
    {% include "snipet.html" %}
  {% endwith %} 
{% endif %}

or, even better would be to write a method on the model that encapsulates the core logic:

def Patient(models.Model):
    ....
    def get_legally_responsible_party(self):
       if self.age > 18:
          return self
       else:
          return self.parent

Then in the template:

{% with patient.get_legally_responsible_party as p %}
  Do html stuff
{% endwith %} 

Then in the future, if the logic for who is legally responsible changes you have a single place to change the logic -- far more DRY than having to change if statements in a dozen templates.

I think Alt+R+F is the correct one for creating property from a variable declaration

Always : If you always want vertical scrollbar, use overflow-y: scroll;

jsFiddle:

<div style="overflow-y: scroll;">
......
</div>

When needed: If you only want vertical scrollbar when needed, use overflow-y: auto; (You need to specify a height in this case)

jsFiddle:

<div style="overflow-y: auto; height:150px; ">
....
</div>

You could use a "variable" inside the output filename, for example:

/tmp/FetchBlock-${current_date}.txt

current_date:

Returns the current system time formatted as yyyyMMdd_HHmm. An optional argument can be used to provide alternative formatting. The argument must be valid pattern for java.util.SimpleDateFormat.

Or you can also use a system_property or an env_var to specify something dynamic (either one needs to be specified as arguments)

Try this

Snackbar.make(findViewById(android.R.id.content), "Got the Result", Snackbar.LENGTH_LONG)
                        .setAction("Submit", mOnClickListener)
                        .setActionTextColor(Color.RED)
                        .show();

You can chain your wheres directly, without function(q). There's also a nice date handling package in laravel, called Carbon. So you could do something like:

$projects = Project::where('recur_at', '>', Carbon::now())
    ->where('recur_at', '<', Carbon::now()->addWeek())
    ->where('status', '<', 5)
    ->where('recur_cancelled', '=', 0)
    ->get();

Just make sure you require Carbon in composer and you're using Carbon namespace (use Carbon\Carbon;) and it should work.

EDIT: As Joel said, you could do:

$projects = Project::whereBetween('recur_at', array(Carbon::now(), Carbon::now()->addWeek()))
    ->where('status', '<', 5)
    ->where('recur_cancelled', '=', 0)
    ->get();

You could use a watch instead, because that has the old and new value, but then you're adding to the digest cycle.

I'd just keep a second variable in the controller and set that.

You don't have to use gdb. GCC will do it.

 gcc -S foo.c

This will create foo.s which is the assembly.

gcc -m32 -c -g -Wa,-a,-ad foo.c > foo.lst

The above version will create a listing file that has both the C and the assembly generated by it. GCC FAQ

You can use set to remove duplicates:

mylist = list(set(mylist))

But note the results will be unordered. If that's an issue:

mylist.sort()

If getData is protected then try making it public. The problem could exist in JAVA 1.6 and be absent in 1.5x

I got this for your problem. Illegal access error

I think the nearest in the .NET Framework is

string.Split()

rem This is the command line version
cscript "C:\Users\guest\Desktop\123\MyScript.vbs"

OR

rem This is the windowed version
wscript "C:\Users\guest\Desktop\123\MyScript.vbs"

You can also add the option //e:vbscript to make sure the scripting engine will recognize your script as a vbscript.

Windows/DOS batch files doesn't require escaping \ like *nix.

You can still use "C:\Users\guest\Desktop\123\MyScript.vbs", but this requires the user has *.vbs associated to wscript.

Recently I came across an issue in grep. I was trying to match the pattern x.y.z and grep returned x.y-z.Using some regular expression we may can overcome this, but with grep whole word matching did not help. Since the script I was writing is a generic one, I cannot restrict search for a specific way as in like x.y.z or x.y-z ..

Quick way I figured is to run a grep and then a condition check var="x.y.z" var1=grep -o x.y.z file.txt if [ $var1 == $var ] echo "Pattern match exact" else echo "Pattern does not match exact" fi

Just adding this for reference in case anybody needs to restart and immediatly run a command.

I'm using this approach just to clear RAM from the system. Make sure you have deleted all objects no longer required. Maybe gc() can also help before hand. But nothing will clear RAM better as restarting the R session.

library(rstudioapi)
restartSession(command = "print('x')")

Oracle 11g R2:

create table table1 (
  id number,
  name varchar2(10),
  desc_ varchar2(10)
);

create table table2 (
  id number,
  name varchar2(10),
  desc_ varchar2(10)
);

insert into table1 values(1, 'a', 'abc');
insert into table1 values(2, 'b', 'def');
insert into table1 values(3, 'c', 'ghi');

insert into table2 values(1, 'x', '123');
insert into table2 values(2, 'y', '456');

merge into table1 t1
using (select * from table2) t2
on (t1.id = t2.id)
when matched then update set t1.name = t2.name, t1.desc_ = t2.desc_;

select * from table1;

        ID NAME       DESC_
---------- ---------- ----------
         1 x          123
         2 y          456
         3 c          ghi

You can also use the unix style time to calculate:

$newtime = time() + ($hours * 60 * 60); // hours; 60 mins; 60secs
echo 'Now:       '. date('Y-m-d') ."\n";
echo 'Next Week: '. date('Y-m-d', $newtime) ."\n";

chart.series[0].setData(data,true);

The setData method itself will call the redraw method

Notepad++ works just fine, although I choose to stick with Notepad, -m, or even sometimes the built-in "edit."

The problem you are encountering using Notepad++ is related to how Git is launching the editor executable. My solution to this is to set environment variable EDITOR to a batch file, rather than the actual editor executable, that does the following:

start /WAIT "E:\PortableApps\Notepad++Portable\Notepad++Portable.exe" %*

/WAIT tells the command line session to halt until the application exits, thus you will be able to edit to your heart's content while Git happily waits for you. %* passes all arguments to the batch file through to Notepad++.

C:\src> echo %EDITOR%
C:\tools\runeditor.bat

add to your code:

"#include < stdlib.h>"

return EXIT_SUCCESS;

at the end of main()

Please make sure that your file name should not be panda.py or pd.py. Also, make sure that panda is there in your Lib/site-packages directory, if not that you need to install panda using below command line:

pip install pandas

if you work with proxy then try calling below in command prompt:

python.exe -m pip install pandas --proxy="YOUR_PROXY_IP:PORT"

This fixes it:

let str = "This-is-a-news-item-";
str = str.replace(/-/g, ' ');
alert(str);

There were two problems with your code:

1. First, String.replace() doesn’t change the string itself, it returns a changed string.
2. Second, if you pass a string to the replace function, it will only replace the first instance it encounters. That’s why I passed a regular expression with the g flag, for 'global', so that all instances will be replaced.
