QMessageBox includes static methods to quickly ask such questions:

#include <QApplication>
#include <QMessageBox>

int main(int argc, char **argv)
{
    QApplication app{argc, argv};
    while (QMessageBox::question(nullptr,
                                 qApp->translate("my_app", "Test"),
                                 qApp->translate("my_app", "Are you sure you want to quit?"),
                                 QMessageBox::Yes|QMessageBox::No)
           != QMessageBox::Yes)
        // ask again
        ;
}

If your needs are more complex than provided for by the static methods, you should construct a new QMessageBox object, and call its exec() method to show it in its own event loop and obtain the pressed button identifier. For example, we might want to make "No" be the default answer:

#include <QApplication>
#include <QMessageBox>

int main(int argc, char **argv)
{
    QApplication app{argc, argv};
    auto question = new QMessageBox(QMessageBox::Question,
                                    qApp->translate("my_app", "Test"),
                                    qApp->translate("my_app", "Are you sure you want to quit?"),
                                    QMessageBox::Yes|QMessageBox::No,
                                    nullptr);
    question->setDefaultButton(QMessageBox::No);

    while (question->exec() != QMessageBox::Yes)
        // ask again
        ;
}

As long as your selector is actually working, I see nothing wrong with your code that checks the length of the array. That should do what you want. There are a lot of ways to clean up your code to be simpler and more readable. Here's a cleaned up version with notes about what I cleaned up.

var album_text = [];

$("input[name='album_text[]']").each(function() {
    var value = $(this).val();
    if (value) {
        album_text.push(value);
    }
});
if (album_text.length === 0) {
    $('#error_message').html("Error");
}

else {
  //send data
}

Some notes on what you were doing and what I changed.

1. $(this) is always a valid jQuery object so there's no reason to ever check if ($(this)). It may not have any DOM objects inside it, but you can check that with $(this).length if you need to, but that is not necessary here because the .each() loop wouldn't run if there were no items so $(this) inside your .each() loop will always be something.
2. It's inefficient to use $(this) multiple times in the same function. Much better to get it once into a local variable and then use it from that local variable.
3. It's recommended to initialize arrays with [] rather than new Array().
4. if (value) when value is expected to be a string will both protect from value == null, value == undefined and value == "" so you don't have to do if (value && (value != "")). You can just do: if (value) to check for all three empty conditions.
5. if (album_text.length === 0) will tell you if the array is empty as long as it is a valid, initialized array (which it is here).

What are you trying to do with this selector $("input[name='album_text[]']")?

You can use flexbox with flex-grow to push the last element to the right.

<div style="display: flex;">
  <div style="flex-grow: 1;">Left</div>
  <div>Right</div>
</div>

I asked a question that kinda duplicated on this topic a while back, and after excessive research, and seeing a lot of information missing that should be here, I feel I have something valuable to add to this older post.

• Firstly I want to address that there are several ways to obtain the value of a property and store it in a dynamic Variable. The first most popular, and easiest way IMHO would be:

let properyValue = element.style['enter-a-property'];

however I rarely go this route because it doesn't work on property values assigned via style-sheets. To give you an example, I'll demonstrate with a bit of pseudo code.

 let elem = document.getElementById('someDiv');
 let cssProp = elem.style['width'];

Using the code example above; if the width property of the div element that was stored in the 'elem' variable was styled in a CSS style-sheet, and not styled inside of its HTML tag, you are without a doubt going to get a return value of undefined stored inside of the cssProp variable. The undefined value occurs because in-order to get the correct value, the code written inside a CSS Style-Sheet needs to be computed in-order to get the value, therefore; you must use a method that will compute the value of the property who's value lies within the style-sheet.

• Henceforth the getComputedStyle() method!

function getCssProp(){
  let ele = document.getElementById("test");
  let cssProp = window.getComputedStyle(ele,null).getPropertyValue("width");
}

W3Schools getComputedValue Doc This gives a good example, and lets you play with it, however, this link Mozilla CSS getComputedValue doc talks about the getComputedValue function in detail, and should be read by any aspiring developer who isn't totally clear on this subject.

• As a side note, the getComputedValue method only gets, it does not set. This, obviously is a major downside, however there is a method that gets from CSS style-sheets, as well as sets values, though it is not standard Javascript. The JQuery method...

$(selector).css(property,value)

...does get, and does set. It is what I use, the only downside is you got to know JQuery, but this is honestly one of the very many good reasons that every Javascript Developer should learn JQuery, it just makes life easy, and offers methods, like this one, which is not available with standard Javascript. Hope this helps someone!!!

Simple way of creating newtonsoft JObject from Properties.

This is a Sample User Properties

public class User
{
    public string Name;
    public string MobileNo;
    public string Address;
}

and i want this property in newtonsoft JObject is:

JObject obj = JObject.FromObject(new User()
{
    Name = "Manjunath",
    MobileNo = "9876543210",
    Address = "Mumbai, Maharashtra, India",
});

Output will be like this:

{"Name":"Manjunath","MobileNo":"9876543210","Address":"Mumbai, Maharashtra, India"}

 just change it to 

compile 'com.google.android.gms:play-services-maps:9.6.0'
compile 'com.google.android.gms:play-services-location:9.6.0'

this works for me current version is 10.0.1

You can use a ComboBox with its ComboBoxStyle (appears as DropDownStyle in later versions) set to DropDownList. See: http://msdn.microsoft.com/en-us/library/system.windows.forms.comboboxstyle.aspx

• AF = Address Family
• PF = Protocol Family

Meaning, AF_INET refers to addresses from the internet, IP addresses specifically. PF_INET refers to anything in the protocol, usually sockets/ports.

Consider reading the man pages for socket(2) and bind(2). For the sin_addr field, just do something like the following to set it:

struct sockaddr_in addr;
inet_pton(AF_INET, "127.0.0.1", &addr.sin_addr); 

Its fine to just do char **strings;, char **strings = NULL, or char **strings = {NULL}

but to initialize it you'd have to use malloc:

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

int main(){
    // allocate space for 5 pointers to strings
    char **strings = (char**)malloc(5*sizeof(char*));
    int i = 0;
    //allocate space for each string
    // here allocate 50 bytes, which is more than enough for the strings
    for(i = 0; i < 5; i++){
        printf("%d\n", i);
        strings[i] = (char*)malloc(50*sizeof(char));
    }
    //assign them all something
    sprintf(strings[0], "bird goes tweet");
    sprintf(strings[1], "mouse goes squeak");
    sprintf(strings[2], "cow goes moo");
    sprintf(strings[3], "frog goes croak");
    sprintf(strings[4], "what does the fox say?");
    // Print it out
    for(i = 0; i < 5; i++){
        printf("Line #%d(length: %lu): %s\n", i, strlen(strings[i]),strings[i]);
    } 
    //Free each string
    for(i = 0; i < 5; i++){
        free(strings[i]);
    }
    //finally release the first string
    free(strings);
    return 0;
}

You are using wrong formatting sequence for double, you should use %lf instead of %ld:

double a;
scanf("%lf",&a);

Drag & Drop

To install apk in avd, just manually drag and drop the apk file in the opened emulated device

The same if you want to copy a file to the sd card

Use getattr if you have an attribute in string form:

>>> class User(object):
       name = 'John'

>>> u = User()
>>> param = 'name'
>>> getattr(u, param)
'John'

Otherwise use the dot .:

>>> class User(object):
       name = 'John'

>>> u = User()
>>> u.name
'John'

Your friend's PC is missing the runtime support DLLs for your program:

• Visual C++ Redistributable for Visual Studio 2015

The command below will search all the files recursively whose name matches the search pattern and will replace the string:

find /path/to/searchdir/ -name "serachpatter" -type f | xargs sed -i 's/stringone/StrIngTwo/g'

Also if you want to limit the depth of recursion you can put the limits as well:

find /path/to/searchdir/ -name "serachpatter" -type f -maxdepth 4 -mindepth 2 | xargs sed -i 's/stringone/StrIngTwo/g'

You were probably changing the layout margin after it has been drawn. mOldTextView.invalidate() is useless. you needed to call requestLayout() on the parent to relayout the new configuration. When you moved the layout changing code before the drawing took place, everything worked fine.

You can also capture jquery ready event this way:

$('#iframeid').ready(function () {
//Everything you need.
});

Here is a working example:

http://jsfiddle.net/ZrFzF/

You can use the 'describe pod' syntax

For OpenShift use:

oc describe pod <pod-id>  

For vanilla Kubernetes:

kubectl describe pod <pod-id>  

Examine the events of the output. In my case it shows Back-off pulling image coredns/coredns:latest

In this case the image coredns/coredns:latest can not be pulled from the Internet.

Additional debuging steps

1. try to pull the docker image and tag manually on your computer
2. Identify the node by doing a 'kubectl/oc get pods -o wide'
3. ssh into the node (if you can) that can not pull the docker image
4. check that the node can resolve the DNS of the docker registry by performing a ping.
5. try to pull the docker image manually on the node
6. If you are using a private registry, check that your secret exists and the secret is correct. Your secret should also be in the same namespace. Thanks swenzel
7. Some registries have firewalls that limit ip address access. The firewall may block the pull
8. Some CIs create deployments with temporary docker secrets. So the secret expires after a few days (You are asking for production failures...)

Maps have also had factory methods added in Java 9. For up to 10 entries Maps have overloaded constructors that take pairs of keys and values. For example we could build a map of various cities and their populations (according to google in October 2016) as follow:

Map<String, Integer> cities = Map.of("Brussels", 1_139000, "Cardiff", 341_000);

The var-args case for Map is a little bit harder, you need to have both keys and values, but in Java, methods can’t have two var-args parameters. So the general case is handled by taking a var-args method of Map.Entry<K, V> objects and adding a static entry() method that constructs them. For example:

Map<String, Integer> cities = Map.ofEntries(
    entry("Brussels", 1139000), 
    entry("Cardiff", 341000)
);

The accepted answer has a bug in it where it still eats the first character of the input string if the delimiter is not found.

$str = '1-2-3-4-5';
echo substr($str, strrpos($str, '-') + 1);

Produces the expected result: 5

$str = '1-2-3-4-5';
echo substr($str, strrpos($str, ';') + 1);

Produces -2-3-4-5

$str = '1-2-3-4-5';
if (($pos = strrpos($str, ';')) !== false)
    echo substr($str, $pos + 1);
else
    echo $str;

Produces the whole string as desired.

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

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

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

Just also to draw your attention to this:

https://code.msdn.microsoft.com/windowsdesktop/C-and-Python-interprocess-171378ee

It works great.

yes you can do that.

declaring class abstract means that class will not be instantiated by any other class.

and there should be at least one abstract method inside that and meaning of that you can declare abstract method in that class if you are not declaring method than its ok.

example:

public abstract class abs {

    protected int cx = 0, cy = 0;

    public void p() {
        System.out.print("hello");
    }
}

this will work for sure.

I suggest using the amazing tool direnv. With it you can inject environment variables once you cd into the project. These steps worked for me:

.envrc file

source_up
dotenv

.env file

_JAVA_OPTIONS="-DYourEnvHere=123"

replace class:

echo str_replace('sub-menu', 'menu menu_sub', wp_nav_menu( array(
    'echo' => false,
    'theme_location' => 'sidebar-menu',
    'items_wrap' => '<ul class="menu menu_sidebar">%3$s</ul>' 
  ) )
);

This is a good thing to handle with a revision control system. That way when you get a bug report from a user, you can check out that revision of code and (hopefully) reproduce the bug running the exact same code as the user.

The idea is that every time you do a build, you will run a script that gets the current revision number of your code and updates a file within your project (usually with some form of token replacement). You can then write an error handling routine that always includes the revision number in the error output, or you can display it on an "About" page.

In some cases you might end up having chain of observables, wherein your observable would return another observable. 'flatmap' kind of unwraps the second observable which is buried in the first one and let you directly access the data second observable is spitting out while subscribing.

Just adding another solution that works for me.. You can simply append it in the marker options:

var marker = new google.maps.Marker({
    map: map, 
    position: position,

    // Custom Attributes / Data / Key-Values
    store_id: id,
    store_address: address,
    store_type: type
});

And then retrieve them with:

marker.get('store_id');
marker.get('store_address');
marker.get('store_type');

Just subtract the number of milliseconds in an hour from the date.

currentDate.setTime(currentDate.getTime() - 3600 * 1000));

     foreach (DataRow row in DataRow row in GridView1.Rows)
        {
            foreach (DataColumn c in GridView1.Columns)

               bool ckbVal = (bool)(row[c.ColumnName]);

        }

services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_2)
                .AddJsonOptions(options => {
                    var resolver = options.SerializerSettings.ContractResolver;
                    if (resolver != null)
                        (resolver as DefaultContractResolver).NamingStrategy = null;
                });

            services.AddDbContext<PaymentDetailContext>(options => options.UseSqlServer(Configuration.GetConnectionString("DevConnection"))); //Dependency Injection
            // options => options.UseSqlServer() Lamda Expression

            services.AddCors(options =>
            {
                options.AddPolicy(MyAllowSpecificOrigins,
                    builder =>
                    {
                        builder.WithOrigins("http://localhost:4200").AllowAnyHeader()
                                .AllowAnyMethod(); ;
                    });
            });

Hi if you are going to subtract only Integer value from DateTime then you have to write code like this

DateTime.Now.AddHours(-2)

Here I am subtracting 2 hours from the current date and time

I had the same problem in the iphone or desktop, didnt manage to close the dialog when pressing the close button.

i found out that The <button> tag defines a clickable button and is needed to specify the type attribute for a element as follow:

<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>

check the example code for bootstrap modals at : BootStrap javascript Page

If you have the table definition to have an IDENTITY column e.g. IDENTITY(1,1) then don't include MyId in your INSERT INTO statement. The point of IDENTITY is it gives it the next unused value as the primary key value.

insert into MYDB.dbo.MainTable (MyFirstName, MyLastName, MyAddress, MyPort)
values(@myFirstName, @myLastName, @myAddress, @myPort)

There is then no need to pass the @MyId parameter into your stored procedure either. So change it to:

CREATE PROCEDURE [dbo].[sp_Test]
@myFirstName nvarchar(50)
,@myLastName nvarchar(50)
,@myAddress nvarchar(MAX)
,@myPort int

AS 

If you want to know what the ID of the newly inserted record is add

SELECT @@IDENTITY

to the end of your procedure. e.g. http://msdn.microsoft.com/en-us/library/ms187342.aspx

You will then be able to pick this up in which ever way you are calling it be it SQL or .NET.

P.s. a better way to show you table definision would have been to script the table and paste the text into your stackoverflow browser window because your screen shot is missing the column properties part where IDENTITY is set via the GUI. To do that right click the table 'Script Table as' --> 'CREATE to' --> Clipboard. You can also do File or New Query Editor Window (all self explanitory) experient and see what you get.

You need to define further routes in global.asax.cs like this:

routes.MapHttpRoute(
    name: "Api with action",
    routeTemplate: "api/{controller}/{action}/{id}",
    defaults: new { id = RouteParameter.Optional }
);

routes.MapHttpRoute(
    name: "DefaultApi",
    routeTemplate: "api/{controller}/{id}",
    defaults: new { id = RouteParameter.Optional }
);

as answered above by: kcoppock and Joril

go here : https://github.com/android/platform_frameworks_base/tree/master/core/res/res/layout

just right click the layout file you want, then select 'Save As', save somewhere, then copy it in 'layout' folder in your android project(eclipse)...

you can see how the layout looks like :)

way to go...

The codes above wouldn't work in Excel 2010 My code bellow allows you to go through number of sheets you would like then select tables and delete rows

    Selection.AutoFilter

    'Determine if ActiveCell is inside a Table
    On Error GoTo NoTableSelected
    TableName = SelectedCell.ListObject.Name
    Set ActiveTable = ActiveSheet.ListObjects(TableName)
    On Error GoTo 0

    'Clear first Row
    ActiveTable.DataBodyRange.Rows(1).ClearContents
    'Delete all the other rows `IF `they exist
    On Error Resume Next
    ActiveTable.DataBodyRange.Offset(1, 0).Resize(ActiveTable.DataBodyRange.Rows.Count - 1, _
    ActiveTable.DataBodyRange.Columns.Count).Rows.Delete
    Selection.AutoFilter
    On Error GoTo 0
Next i
Exit Sub
'Error Handling
NoTableSelected:
  MsgBox "There is no Table currently selected!", vbCritical

End Sub

If the sent_at field is not there when its not set then:

db.emails.count({sent_at: {$exists: false}})

If its there and null, or not there at all:

db.emails.count({sent_at: null})

If you need to install a global version gulp as described on the gulpjs.com site and still have issues, you may need to clean npm's cache. For instance, if you have previously installed gulp and managed to blow it away by accident, it may not install properly again because it's looking for directories that no longer exist. In which case, run:

sudo npm cache clean

Then install gulp as you normally would.

1. Open IIS Manager from the start button
2. Double click on features delegate
3. Make all the properties read and write
4. go to ISPAI and remove all the permissions

If above not worked properly. Then, make sure that u have installed the visual studio first before installation of IIS,

For better solution uninstall visual studio and then again install first IIS properly then visual studio

I think it is possible for the server to return content in response to a PUT. If you are using a response envelop format that allows for sideloaded data (such as the format consumed by ember-data), then you can also include other objects that may have been modified via database triggers, etc. (Sideloaded data is explicitly to reduce # of requests, and this seems like a fine place to optimize.)

If I just accept the PUT and have nothing to report back, I use status code 204 with no body. If I have something to report, I use status code 200, and include a body.

On Windows 64 bits, just add the following to the PATH environment variable: "C:\Program Files\Tesseract-OCR" and it will work.

var array = [];

//length array now = 0
array[array.length] = 'hello';
//length array now = 1
//            0
//array = ['hello'];//length = 1

There are two flavors of table valued functions. One that is just a select statement and one that can have more rows than just a select statement.

This can not have a variable:

create function Func() returns table
as
return
select 10 as ColName

You have to do like this instead:

create function Func()
returns @T table(ColName int)
as
begin
  declare @Var int
  set @Var = 10
  insert into @T(ColName) values (@Var)
  return
end

This is a working option.

public static String showDuration(LocalTime otherTime){          
    DateTimeFormatter df = DateTimeFormatter.ISO_LOCAL_TIME;
    LocalTime now = LocalTime.now();
    System.out.println("now: " + now);
    System.out.println("otherTime: " + otherTime);
    System.out.println("otherTime: " + otherTime.format(df));

    Duration span = Duration.between(otherTime, now);
    LocalTime fTime = LocalTime.ofNanoOfDay(span.toNanos());
    String output = fTime.format(df);

    System.out.println(output);
    return output;
}

Call the method with

System.out.println(showDuration(LocalTime.of(9, 30, 0, 0)));

Produces something like:

otherTime: 09:30
otherTime: 09:30:00
11:31:27.463
11:31:27.463

Here's a query that will return all results within a range of days.

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">

    <item android:drawable="@drawable/ico_100_checked" android:state_selected="true"/>
    <item android:drawable="@drawable/ico_100_unchecked"/>

</selector>

And in my onCreate I call:

final ImageButton ib = (ImageButton) value.findViewById(R.id.imageButton);

    OnClickListener ocl =new OnClickListener() {
        @Override
        public void onClick(View button) {
            if (button.isSelected()){
                button.setSelected(false);
            } else {
                ib.setSelected(false);
                //put all the other buttons you might want to disable here...
                button.setSelected(true);
            }
        }
    };

ib.setOnClickListener(ocl);
//add ocl to all the other buttons

done. hope this helps. took me a while to figure out.

I had this problem in my .NET Framework Web API, because my model existed in a .NET Standard project that referenced a different version of data annotations.

Adding the ReadAsAsync line below highlighted the cause for me:

public async Task<HttpResponseMessage> Register(RegistrationDetails registrationDetails)
{
    var regDetails = await Request.Content.ReadAsAsync<RegistrationDetails>();

Detecting CSS 3D transforms

Modernizr can detect CSS 3D transforms, yeah. The truthiness of Modernizr.csstransforms3d will tell you if the browser supports them.

The above link lets you select which tests to include in a Modernizr build, and the option you're looking for is available there.

Detecting IE specifically

Alternatively, as user356990 answered, you can use conditional comments if you're searching for IE and IE alone. Rather than creating a global variable, you can use HTML5 Boilerplate's <html> conditional comments trick to assign a class:

<!--[if lt IE 7]>      <html class="no-js lt-ie9 lt-ie8 lt-ie7"> <![endif]-->
<!--[if IE 7]>         <html class="no-js lt-ie9 lt-ie8"> <![endif]-->
<!--[if IE 8]>         <html class="no-js lt-ie9"> <![endif]-->
<!--[if gt IE 8]><!--> <html class="no-js"> <!--<![endif]-->

If you already have jQuery initialised, you can just check with $('html').hasClass('lt-ie9'). If you need to check which IE version you're in so you can conditionally load either jQuery 1.x or 2.x, you can do something like this:

myChecks.ltIE9 = (function(){
    var htmlElemClasses = document.querySelector('html').className.split(' ');
    if (!htmlElemClasses){return false;}
    for (var i = 0; i < htmlElemClasses.length; i += 1 ){
      var klass = htmlElemClasses[i];
      if (klass === 'lt-ie9'){
        return true;
      }
    }
    return false;
}());

N.B. IE conditional comments are only supported up to IE9 inclusive. From IE10 onwards, Microsoft encourages using feature detection rather than browser detection.

Whichever method you choose, you'd then test with

if ( myChecks.ltIE9 || Modernizr.csstransforms3d ){
    // iframe or flash fallback
} 

Don't take that || literally, of course.

In your onCreate(), write the following

LinearLayout myRoot = (LinearLayout) findViewById(R.id.my_root);
LinearLayout a = new LinearLayout(this);
a.setOrientation(LinearLayout.HORIZONTAL);
a.addView(view1);
a.addView(view2);
a.addView(view3);
myRoot.addView(a);

view1, view2 and view3 are your TextViews. They're easily created programmatically.

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

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

A simple solution if you are using the Entity Framework is the add a partical class and define a constructor for the entity as the framework does not define one. For example if you have an entity named Example you would put the following code in a seperate file.

namespace EntityExample
{
    public partial class Example : EntityObject
    {
        public Example()
        {
            // Initialize certain default values here.
            this._DateCreated = DateTime.Now;
        }
    }
}

if(isset($_POST['form_field_name'])) {
    $variable_name = $_POST['form_field_name'];
}

%~dp0 will be the directory. Here's some documentation on all of the path modifiers. Fun stuff :-)

To remove the final backslash, you can use the :n,m substring syntax, like so:

SET mypath=%~dp0
echo %mypath:~0,-1%

I don't believe there's a way to combine the %0 syntax with the :~n,m syntax, unfortunately.

Performance characteristics for lists are described on Effbot.

Python lists are actually implemented as vector for fast random access, so the container will basically hold as many items as there is space for in memory. (You need space for pointers contained in the list as well as space in memory for the object(s) being pointed to.)

Appending is O(1) (amortized constant complexity), however, inserting into/deleting from the middle of the sequence will require an O(n) (linear complexity) reordering, which will get slower as the number of elements in your list.

Your sorting question is more nuanced, since the comparison operation can take an unbounded amount of time. If you're performing really slow comparisons, it will take a long time, though it's no fault of Python's list data type.

Reversal just takes the amount of time it required to swap all the pointers in the list (necessarily O(n) (linear complexity), since you touch each pointer once).

It seems like what you want is http://msdn.microsoft.com/en-us/library/ms186323.aspx.

In your example it would be (starts with):

set @isExpress = (CharIndex('Express Edition', @edition) = 1)

Or contains

set @isExpress = (CharIndex('Express Edition', @edition) >= 1)

Use whichever suits your need.

Output (same for all):

You have a lot of unnecessary keyframes. Don't think of keyframes as individual frames, think of them as "steps" in your animation and the computer fills in the frames between the keyframes.

Here is a solution that cleans up a lot of code and makes the animation start from the center:

.gps_ring {
    border: 3px solid #999;
    -webkit-border-radius: 30px;
    height: 18px;
    width: 18px;
    position: absolute;
    left:20px;
    top:214px;
    -webkit-animation: pulsate 1s ease-out;
    -webkit-animation-iteration-count: infinite; 
    opacity: 0.0
}
@-webkit-keyframes pulsate {
    0% {-webkit-transform: scale(0.1, 0.1); opacity: 0.0;}
    50% {opacity: 1.0;}
    100% {-webkit-transform: scale(1.2, 1.2); opacity: 0.0;}
}

You can see it in action here: http://jsfiddle.net/Fy8vD/

A subtle alternative to MaxNoe's answer where you aren't explicitly setting the ticks but instead setting the cadence.

import matplotlib.pyplot as plt
from matplotlib.ticker import (AutoMinorLocator, MultipleLocator)

fig, ax = plt.subplots(figsize=(10, 8))

# Set axis ranges; by default this will put major ticks every 25.
ax.set_xlim(0, 200)
ax.set_ylim(0, 200)

# Change major ticks to show every 20.
ax.xaxis.set_major_locator(MultipleLocator(20))
ax.yaxis.set_major_locator(MultipleLocator(20))

# Change minor ticks to show every 5. (20/4 = 5)
ax.xaxis.set_minor_locator(AutoMinorLocator(4))
ax.yaxis.set_minor_locator(AutoMinorLocator(4))

# Turn grid on for both major and minor ticks and style minor slightly
# differently.
ax.grid(which='major', color='#CCCCCC', linestyle='--')
ax.grid(which='minor', color='#CCCCCC', linestyle=':')

Sometimes you don't have the option of editing the php file to set $_GET to the parameters passed in, and sometimes you can't or don't want to install php-cgi.

I found this to be the best solution for that case:

php -r '$_GET["key"]="value"; require_once("script.php");' 

This avoids altering your php file and lets you use the plain php command. If you have php-cgi installed, by all means use that, but this is the next best thing. Thought this options was worthy of mention

the -r means run the php code in the string following. you set the $_GET value manually there, and then reference the file you want to run.

Its worth noting you should run this in the right folder, often but not always the folder the php file is in. Requires statements will use the location of your command to resolve relative urls, NOT the location of the file

I think the question is incomplete. if you meant that you wish to get the type information of some typeclass then below:

If you wish to print as you have specified then:

scala>  def manOf[T: Manifest](t: T): Manifest[T] = manifest[T]
manOf: [T](t: T)(implicit evidence$1: Manifest[T])Manifest[T]

scala> val x = List(1,2,3)
x: List[Int] = List(1, 2, 3)

scala> println(manOf(x))
scala.collection.immutable.List[Int]

If you are in repl mode then

scala> :type List(1,2,3)
List[Int]

Or if you just wish to know what the class type then as @monkjack explains "string".getClass might solve the purpose

Default values are only used if the arguments are not specified. In your case you did specify the arguments - both were supplied, with a value of NULL. (Yes, in this case NULL is considered a real value :-). Try:

EXEC TEST()

Share and enjoy.

Addendum: The default values for procedure parameters are certainly buried in a system table somewhere (see the SYS.ALL_ARGUMENTS view), but getting the default value out of the view involves extracting text from a LONG field, and is probably going to prove to be more painful than it's worth. The easy way is to add some code to the procedure:

CREATE OR REPLACE PROCEDURE TEST(X IN VARCHAR2 DEFAULT 'P',
                                 Y IN NUMBER DEFAULT 1)
AS
  varX VARCHAR2(32767) := NVL(X, 'P');
  varY NUMBER          := NVL(Y, 1);
BEGIN
  DBMS_OUTPUT.PUT_LINE('X=' || varX || ' -- ' || 'Y=' || varY);
END TEST;

If all you are doing is adding css to the page, then I would suggest you use the Stylish addon, and write a user style instead of a user script, because a user style is more efficient and appropriate.

Python Extension. From the Python Docs:

The solution chosen by the Perl developers was to use (?...) as the extension syntax. ? immediately after a parenthesis was a syntax error because the ? would have nothing to repeat, so this didn’t introduce any compatibility problems. The characters immediately after the ? indicate what extension is being used, so (?=foo) is one thing (a positive lookahead assertion) and (?:foo) is something else (a non-capturing group containing the subexpression foo).

Python supports several of Perl’s extensions and adds an extension syntax to Perl’s extension syntax.If the first character after the question mark is a P, you know that it’s an extension that’s specific to Python

Based on twitter scroll trouble (http://ejohn.org/blog/learning-from-twitter/).

Here is my solution, throttling the js scroll event (usefull for mobile devices)

JS:

$(function() {
    var $document, didScroll, offset;
    offset = $('.menu').position().top;
    $document = $(document);
    didScroll = false;
    $(window).on('scroll touchmove', function() {
      return didScroll = true;
    });
    return setInterval(function() {
      if (didScroll) {
        $('.menu').toggleClass('fixed', $document.scrollTop() > offset);
        return didScroll = false;
      }
    }, 250);
  });

CSS:

.menu {
  background: pink;
  top: 5px;
}

.fixed {
  width: 100%;
  position: fixed;
  top: 0;
}

HTML:

<div class="menu">MENU FIXED ON TOP</div>

http://codepen.io/anon/pen/BgqHw

I have the almost the same situation as yours; that if the screen width is less than the my specified width it should hide the div. This is the jquery code I used that worked for me.

$(window).resize(function() {

  if ($(this).width() < 1024) {

    $('.divIWantedToHide').hide();

  } else {

    $('.divIWantedToHide').show();

    }

});

Click File > Preferences > Keyboard Shortcuts:

Search for copyLinesDownAction or copyLinesUpAction in your keyboard shortcuts

Usually it is SHIFT+ALT + ?

Update for Ubuntu:

It seems that Ubuntu is hiding that shortcut from being seen by VSCode (i.e. it uses it probably by its own). There is an issue about that on GitHub.

In order to work in Ubuntu you will have to define your own shortcut, e.g. to copy the line using ctrl+shift+alt+j and CTRL +SHIFT + ALT + k you could use a keybindings.json like this:

[
    { "key": "ctrl+shift+alt+j", "command": "editor.action.copyLinesDownAction",
                                    "when": "editorTextFocus && !editorReadonly" },
    { "key": "ctrl+shift+alt+k", "command": "editor.action.copyLinesUpAction",
                                    "when": "editorTextFocus && !editorReadonly" }
]

SQLite Boolean Datatype:
SQLite does not have a separate Boolean storage class. Instead, Boolean values are stored as integers 0 (false) and 1 (true).

You can convert boolean to int in this way:

int flag = (boolValue)? 1 : 0;

You can convert int back to boolean as follows:

 // Select COLUMN_NAME  values from db. 
 // This will be integer value, you can convert this int value back to Boolean as follows
Boolean flag2 = (intValue == 1)? true : false;

If you want to explore sqlite, here is a tutorial.
I have given one answer here. It is working for them.

The DISTINCT Keyword

SELECT DISTINCT * FROM MyFooTable;

If you group by all columns, you are just requesting that duplicate data be removed.

For example a table with the following data:

 id |     value      
----+----------------
  1 | foo
  2 | bar
  1 | foo
  3 | something else

If you perform the following query which is essentially the same as SELECT * FROM MyFooTable GROUP BY * if you are assuming * means all columns:

SELECT * FROM MyFooTable GROUP BY id, value;

 id |     value      
----+----------------
  1 | foo
  3 | something else
  2 | bar

It removes all duplicate values, which essentially makes it semantically identical to using the DISTINCT keyword with the exception of the ordering of results. For example:

SELECT DISTINCT * FROM MyFooTable;

 id |     value      
----+----------------
  1 | foo
  2 | bar
  3 | something else

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++) {

    }

Update (as 2019):

cd ~/.vim
git clone git://github.com/tpope/vim-haml.git pack/bundle/start/haml

Explanation (from :h pack ad :h packages):

1. All the directories found are added to runtimepath. They must be in ~/.vim/pack/whatever/start [you can only change whatever].
2. the plugins found in the plugins dir in runtimepath are sourced.

So this load the plugin on start (hence the name start).

You can also get optional plugin (loaded with :packadd) if you put them in ~/.vim/pack/bundle/opt

Generate a migration and use change_column_default, is succinct and reversible:

class SetDefaultAgeInPeople < ActiveRecord::Migration[5.2]
  def change
    change_column_default :people, :age, { from: nil, to: 0 }
  end
end

it's in <algorithm> and called std::find.

For a load with more writes and reads, you will benefit from InnoDB. Because InnoDB provides row-locking rather than table-locking, your SELECTs can be concurrent, not just with each other but also with many INSERTs. However, unless you are intending to use SQL transactions, set the InnoDB commit flush to 2 (innodb_flush_log_at_trx_commit). This gives you back a lot of raw performance that you would otherwise lose when moving tables from MyISAM to InnoDB.

Also, consider adding replication. This gives you some read scaling and since you stated your reads don't have to be up-to-date, you can let the replication fall behind a little. Just be sure that it can catch up under anything but the heaviest traffic or it will always be behind and will never catch up. If you go this way, however, I strongly recommend you isolate reading from the slaves and replication lag management to your database handler. It is so much simpler if the application code does not know about this.

Finally, be aware of different table loads. You will not have the same read/write ratio on all tables. Some smaller tables with near 100% reads could afford to stay MyISAM. Likewise, if you have some tables that are near 100% write, you may benefit from INSERT DELAYED, but that is only supported in MyISAM (the DELAYED clause is ignored for an InnoDB table).

But benchmark to be sure.

Is not nice to define textbox width without using CSS, be warned ;-)

<input type="text" name="d" value="4" size="4" />

Dataframes have a sort_index method which returns a copy by default. Pass inplace=True to operate in place.

import pandas as pd
df = pd.DataFrame([1, 2, 3, 4, 5], index=[100, 29, 234, 1, 150], columns=['A'])
df.sort_index(inplace=True)
print(df.to_string())

Gives me:

     A
1    4
29   2
100  1
150  5
234  3

IO manipulators are what you need. setw, in particular. Here's an example from the reference page:

// setw example
#include <iostream>
#include <iomanip>
using namespace std;

int main () {
  cout << setw (10);
  cout << 77 << endl;
  return 0;
}

Justifying the field to the left and right is done with the left and right manipulators.

Also take a look at setfill. Here's a more complete tutorial on formatting C++ output with io manipulators.

For those of you landing here but searching how to break out of a loop that contains an include statement use return instead of break or continue.

<?php

for ($i=0; $i < 100; $i++) { 
    if (i%2 == 0) {
        include(do_this_for_even.php);
    }
    else {
        include(do_this_for_odd.php);
    }
}

?>

If you want to break when being inside do_this_for_even.php you need to use return. Using break or continue will return this error: Cannot break/continue 1 level. I found more details here

Plugins -> Plugin Manager -> Show Plugin Manager -> Setting -> Check mark On Force HTTP instead of HTTPS for downloading Plugin List & Use development plugin list (may contain untested, unvalidated or un-installable plugins). -> OK.

After thinking this through carefully, I think this is the best way. It lets you step off in the middle easily without using break, which I think is important, and it requires minimal computation, so I think it's the fastest. It also doesn't require that li be a list or tuple. It could be any iterator.

from itertools import cycle

li = [0, 1, 2, 3]

running = True
licycle = cycle(li)
# Prime the pump
nextelem = next(licycle)
while running:
    thiselem, nextelem = nextelem, next(licycle)

I'm leaving the other solutions here for posterity.

All of that fancy iterator stuff has its place, but not here. Use the % operator.

li = [0, 1, 2, 3]

running = True
while running:
    for idx, elem in enumerate(li):
        thiselem = elem
        nextelem = li[(idx + 1) % len(li)]

Now, if you intend to infinitely cycle through a list, then just do this:

li = [0, 1, 2, 3]

running = True
idx = 0
while running:
    thiselem = li[idx]
    idx = (idx + 1) % len(li)
    nextelem = li[idx]

I think that's easier to understand than the other solution involving tee, and probably faster too. If you're sure the list won't change size, you can squirrel away a copy of len(li) and use that.

This also lets you easily step off the ferris wheel in the middle instead of having to wait for the bucket to come down to the bottom again. The other solutions (including yours) require you check running in the middle of the for loop and then break.

DISCLAIMER: I'm the author of kids.cache.

You should check kids.cache, it provides a @cache decorator that works on python 2 and python 3. No dependencies, ~100 lines of code. It's very straightforward to use, for instance, with your code in mind, you could use it like this:

pip install kids.cache

Then

from kids.cache import cache
...
class MyClass(object):
    ...
    @cache            # <-- That's all you need to do
    @property
    def name(self):
        return 1 + 1  # supposedly expensive calculation

Or you could put the @cache decorator after the @property (same result).

Using cache on a property is called lazy evaluation, kids.cache can do much more (it works on function with any arguments, properties, any type of methods, and even classes...). For advanced users, kids.cache supports cachetools which provides fancy cache stores to python 2 and python 3 (LRU, LFU, TTL, RR cache).

IMPORTANT NOTE: the default cache store of kids.cache is a standard dict, which is not recommended for long running program with ever different queries as it would lead to an ever growing caching store. For this usage you can plugin other cache stores using for instance (@cache(use=cachetools.LRUCache(maxsize=2)) to decorate your function/property/class/method...)

This could be due to a face palm moment: if you switch between several clones it is easy to find yourself in the wrong source tree trying to pull a non-existent branch. It is easier when the clones have similar names, or the repos are distinct clones for the same project from each of multiple contributors. A new git clone would obviously seem to solve that "problem" when the real problem is losing focus or working context or both.

Just wondering why you are using 2 directives?

It seems like, in this case it would be more straightforward to have a controller as the parent - handle adding the data from your service to its $scope, and pass the model you need from there into your warrantyDirective.

Or for that matter, you could use 0 directives to achieve the same result. (ie. move all functionality out of the separate directives and into a single controller).

It doesn't look like you're doing any explicit DOM transformation here, so in this case, perhaps using 2 directives is overcomplicating things.

Alternatively, have a look at the Angular documentation for directives: http://docs.angularjs.org/guide/directive The very last example at the bottom of the page explains how to wire up dependent directives.

Make all parent element with 100% width and 100% height and use display: table; and display:table-cell;, check the working sample.

The Spinner class implements DialogInterface.OnClickListener, thereby effectively hijacking the standard View.OnClickListener.

If you are not using a sub-classed Spinner or don't intend to, choose another answer.

Otherwise just add the following code to your custom Spinner:

@Override
/** Override triggered on 'tap' of closed Spinner */
public boolean performClick() {
    // [ Do anything you like here ]
    return super.performClick();
}

Example: Display a pre-supplied hint via Snackbar whenever the Spinner is opened:

private String sbMsg=null;      // Message seen by user when Spinner is opened.
public void setSnackbarMessage(String msg) { sbMsg=msg; }
@Override
/** Override triggered on 'tap' of closed Spinner */
public boolean performClick() {
    if (sbMsg!=null && !sbMsg.isEmpty()) { /* issue Snackbar */ }
    return super.performClick();

A custom Spinner is a terrific starting point for programmatically standardising Spinner appearance throughout your project.

I had the same issue as above and I am using PostgreSQL 10.5. I tried everything as above but nothing seems to be working.

Then I closed the pgadmin and opened a session for the PSQL terminal. Logged into the PSQL and connected to the database and schema respectively :

\c <DATABASE_NAME>;
set search_path to <SCHEMA_NAME>;

Then, restarted the pgadmin console and then I was able to work without issue in the query-tool of the pagadmin.

Ctrl + Alt + MouseWheel will work in Visual Studio 2015.

The code looks strange because the printf are not in any function blocks.

If speed and memory is no problem, dom4j is a really good option. If you need speed, using a StAX parser like Woodstox is the right way, but you have to write more code to get things done and you have to get used to process XML in streams.

1. First, check existing mode(s) are using the following command in your terminal:

   $ mysql -u root -p -e "SHOW VARIABLES LIKE 'sql_mode';"

   or

   mysql> show variables like 'sql_mode';

   You would see an output like below

   

2. Disable mode(s) via my.cnf: In this case, you need to remove NO_ZERO_IN_DATE, NO_ZERO_DATE modes

   Open my.cnf file (Generally you could find my.cnf file located in /etc/my.cnf or /etc/mysql/my.cnf)

   Update modes in my.cnf under [mysqld] heading

   sql_mode=ONLY_FULL_GROUP_BY,STRICT_TRANS_TABLES,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION

   Here I have omitted NO_ZERO_IN_DATE, NO_ZERO_DATE modes

3. Restart mysql server

   $ /etc/init.d/mysql restart

Even if you do xcode-select --install it was not fixing that for me as it showed some network error. The problem was that it could not connect to the app store. I did the following to fix it.

1. Open keystore
2. Go to system root and select certificates.
3. Open digicert high assurance EV.
4. Expand the trust section, mark it as never trust.
5. Restart system now repeat step 1, 2, 3. and mark the trust policy as back to use system defaults.

Your app store should work now and you should be able to run xcode-select --install

HashMap and HashTable

• Some important points about HashMap and HashTable. please read below details.

1) Hashtable and Hashmap implement the java.util.Map interface 2) Both Hashmap and Hashtable is the hash based collection. and working on hashing. so these are similarity of HashMap and HashTable.

• What is the difference between HashMap and HashTable?

1) First difference is HashMap is not thread safe While HashTable is ThreadSafe
2) HashMap is performance wise better because it is not thread safe. while Hashtable performance wise is not better because it is thread safe. so multiple thread can not access Hashtable at the same time.

I have used the following for this issue. I know it's not very elegant, but it's working.

DateTime zeroTime = new DateTime(1, 1, 1);
var date1 = new DateTime(1983, 03, 04);
var date2 = DateTime.Now;
var dif = date2 - date1;
int years = (zeroTime + dif).Year - 1;
Log.DebugFormat("Years -->{0}", years);

If DAO use

RS.Move 0, RS.LastModified
lngID = RS!AutoNumberFieldName

If ADO use

cn.Execute "INSERT INTO TheTable.....", , adCmdText + adExecuteNoRecords
Set rs = cn.Execute("SELECT @@Identity", , adCmdText)
Debug.Print rs.Fields(0).Value

cn being a valid ADO connection, @@Identity will return the last Identity (Autonumber) inserted on this connection.

Note that @@Identity might be troublesome because the last generated value may not be the one you are interested in. For the Access database engine, consider a VIEW that joins two tables, both of which have the IDENTITY property, and you INSERT INTO the VIEW. For SQL Server, consider if there are triggers that in turn insert records into another table that also has the IDENTITY property.

BTW DMax would not work as if someone else inserts a record just after you've inserted one but before your Dmax function finishes excecuting, then you would get their record.

Correct the ORACLE_HOME path.

There could be two oracle clients in the system.

I had the same issue, the reason being my ORACLE_HOME was pointed to the oracle installation which was not having the tns.ora file.

Changing the ORACLE_HOME to the Oracle directory which is having the tns.ora solved it.

tns.ora lies in client2\network\admin\

Go to Network Preferences.

At the bottom of the list of network adapters, click the + icons

Select the existing interface that you want to arp (say Ethernet 1), and give the Service Name that you want for the new port (say Ethernet 1.1) then press create.

Now you have the new virtual interface in the gui and can manage IP addresses etc it in the normal way.

ifconfig -a will confirm that you have multiple IPs on the interface, and these will still be there when you reboot.

Its a Mac. Don't fight it, do it the easy way.

You can use linq:

var q = from tag in Week orderby Convert.ToDateTime(tag.date) select tag;
List<cTag> Sorted = q.ToList()

Currently there is still no native solution in Javascript for this behavior. Tagged templates are something related, but don't solve it.

Here there is a refactor of alex's solution with an object for replacements.

The solution uses arrow functions and a similar syntax for the placeholders as the native Javascript interpolation in template literals ({} instead of %%). Also there is no need to include delimiters (%) in the names of the replacements.

There are two flavors (three with the update): descriptive, reduced, elegant reduced with groups.

Descriptive solution:

const stringWithPlaceholders = 'My Name is {name} and my age is {age}.';

const replacements = {
  name: 'Mike',
  age: '26',
};

const string = stringWithPlaceholders.replace(
  /{\w+}/g,
  placeholderWithDelimiters => {
    const placeholderWithoutDelimiters = placeholderWithDelimiters.substring(
      1,
      placeholderWithDelimiters.length - 1,
    );
    const stringReplacement = replacements[placeholderWithoutDelimiters] || placeholderWithDelimiters;
    return stringReplacement;
  },
);

console.log(string);

Reduced solution:

const stringWithPlaceholders = 'My Name is {name} and my age is {age}.';

const replacements = {
  name: 'Mike',
  age: '26',
};

const string = stringWithPlaceholders.replace(/{\w+}/g, placeholder =>
  replacements[placeholder.substring(1, placeholder.length - 1)] || placeholder
);

console.log(string);

UPDATE 2020-12-10

Elegant reduced solution with groups, as suggested by @Kade in the comments:

const stringWithPlaceholders = 'My Name is {name} and my age is {age}.';

const replacements = {
  name: 'Mike',
  age: '26',
};

const string = stringWithPlaceholders.replace(
  /{(\w+)}/g, 
  (placeholderWithDelimiters, placeholderWithoutDelimiters) =>
    replacements[placeholderWithoutDelimiters] || placeholderWithDelimiters
);

console.log(string);

UPDATE 2021-01-21

Support empty string as a replacement, as suggested by @Jesper in the comments:

const stringWithPlaceholders = 'My Name is {name} and my age is {age}.';

const replacements = {
  name: 'Mike',
  age: '',
};

const string = stringWithPlaceholders.replace(
  /{(\w+)}/g, 
  (placeholderWithDelimiters, placeholderWithoutDelimiters) =>
  replacements.hasOwnProperty(placeholderWithoutDelimiters) ? 
    replacements[placeholderWithoutDelimiters] : placeholderWithDelimiters
);

console.log(string);

I found a very simple method which is more modern and elegant way.

const el = document.querySelector('.m-element');

// To toggle
['class1', 'class2'].map((e) => el.classList.toggle(e));

// To add
['class1', 'class2'].map((e) => el.classList.add(e));

// To remove
['class1', 'class2'].map((e) => el.classList.remove(e));

Good thing is you can extend the class array or use any coming from API easily.

Set the val to ""

function clear_form_elements(ele) {

        $(ele).find(':input').each(function() {
            switch(this.type) {
                case 'password':
                case 'select-multiple':
                case 'select-one':
                case 'text':
                case 'textarea':
                    $(this).val('');
                    break;
                case 'checkbox':
                case 'radio':
                    this.checked = false;
            }
        });

    }

<input onclick="clear_form_elements(this.form)" type="button" value="Clear All" />  
<input onclick="clear_form_elements('#example_1')" type="button" value="Clear Section 1" />
<input onclick="clear_form_elements('#example_2')" type="button" value="Clear Section 2" />
<input onclick="clear_form_elements('#example_3')" type="button" value="Clear Section 3" />

You could also try something like this:

  function clearForm(form) {

    // iterate over all of the inputs for the form

    // element that was passed in

    $(':input', form).each(function() {

      var type = this.type;

      var tag = this.tagName.toLowerCase(); // normalize case

      // it's ok to reset the value attr of text inputs,

      // password inputs, and textareas

      if (type == 'text' || type == 'password' || tag == 'textarea')

        this.value = "";

      // checkboxes and radios need to have their checked state cleared

      // but should *not* have their 'value' changed

      else if (type == 'checkbox' || type == 'radio')

        this.checked = false;

      // select elements need to have their 'selectedIndex' property set to -1

      // (this works for both single and multiple select elements)

      else if (tag == 'select')

        this.selectedIndex = -1;

    });

  };

Add the type for the script

<script src="https://maps.googleapis.com/maps/api/js" type="text/javascript"></script>

So the important part is the type text/javascript.

1. Put source files into a zip file (as it does for java source)
2. Go to Project properties -> Libraries
3. Select Source attachment and click 'Edit'
4. On Source Attachment Configuration click 'Variable'
5. On "Variable Selection" click 'New'
6. Put a meaningful name and select the zip file created in step 1

The "official" way to get the vs2015 is to go to https://my.visualstudio.com/ ; join the " Visual Studio Dev Essentials" and then search the relevant file to download https://my.visualstudio.com/Downloads?q=Visual%20Studio%202015%20with%20Update%203

You can't do it with pure html/javascript. This is because you have a seperate connection to the webserver to retrieve a separate file (the image) and a normal webserver will serve the file with content headers set so that the browser reading the content type will decide that the type can be handled internally.

The way to force the browser not to handle the file internally is to change the headers (content-disposition prefereably, or content-type) so the browser will not try to handle the file internally. You can either do this by writing a script on the webserver that dynamically sets the headers (i.e. download.php) or by configuring the webserver to return different headers for the file you want to download. You can do this on a per-directory basis on the webserver, which would allow you to get away without writing any php or javascript - simply have all your download images in that one location.

Simple thing i did to get it working:

Went in eclipse > Window > Preferences

(Optional)typed in the search box "file" to help trim the tree of options. Went to General > Editors > File associations.

Clicked the ".class" type. Below there were 2 editors present, i clicked on the "Class File Editor" - the one with the icon from JD, clicked the "Default" button on the right.

Done. Now all ur class are belong to us.

Personally, for me, the best solution for a similar issue was:

HTML

<input type="radio" name="selectAll" value="true" />
<input type="radio" name="selectAll" value="false" />

JQuery

var $selectAll = $( "input:radio[name=selectAll]" );
    $selectAll.on( "change", function() {
         console.log( "selectAll: " + $(this).val() );
         // or
         alert( "selectAll: " + $(this).val() );
    });

*The event "click" can work in place of "change" as well.

Hope this helps!

super is used to call the constructor, methods and properties of parent class.

Well, actually, React is not suitable for calling child methods from the parent. Some frameworks, like Cycle.js, allow easily access data both from parent and child, and react to it.

Also, there is a good chance you don't really need it. Consider calling it into existing component, it is much more independent solution. But sometimes you still need it, and then you have few choices:

• Pass method down, if it is a child (the easiest one, and it is one of the passed properties)
• add events library; in React ecosystem Flux approach is the most known, with Redux library. You separate all events into separated state and actions, and dispatch them from components
• if you need to use function from the child in a parent component, you can wrap in a third component, and clone parent with augmented props.

UPD: if you need to share some functionality which doesn't involve any state (like static functions in OOP), then there is no need to contain it inside components. Just declare it separately and invoke when need:

let counter = 0;
function handleInstantiate() {
   counter++;
}

constructor(props) {
   super(props);
   handleInstantiate();
}

Set these on php.ini:

;display_startup_errors = On
display_startup_errors=off
display_errors =on
html_errors= on

From your PHP page, use a suitable filter for error reporting.

error_reporting(E_ALL);

Filers can be made according to requirements.

E_ALL
E_ALL | E_STRICT

Another way starting from c# 7.0 would be using local functions. You could name the local function with a meaningful name, and call it directly before declaring it (for clarity). Here is your example rewritten:

public void Method()
{
    // Some code here
    bool something = true, something2 = true;

    DoSomething();
    void DoSomething()
    {
        if (something)
        {
            //some code
            if (something2)
            {
                // now I should break from ifs and go to te code outside ifs
                return;
            }
            return;
        }
    }

    // The code i want to go if the second if is true
    // More code here
}

The following code assumes:

• There is always a single text node within the editable <div> and no other nodes
• The editable div does not have the CSS white-space property set to pre

Found a workaround solution. Say that you want to scroll to an div, Element here for example, and you want to have a spacing of 20px above it. Set the ref to a created div above it:

<div ref={yourRef} style={{position: 'relative', bottom: 20}}/> <Element />

Doing so will create this spacing that you want.

If you have a header, create an empty div as well behind the header and assign to it a height equal to the height of the header and reference it.

Yes, it is a hash mapping or hash table. You can read a description of python's dict implementation, as written by Tim Peters, here.

That's why you can't use something 'not hashable' as a dict key, like a list:

>>> a = {}
>>> b = ['some', 'list']
>>> hash(b)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: list objects are unhashable
>>> a[b] = 'some'
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: list objects are unhashable

You can read more about hash tables or check how it has been implemented in python and why it is implemented that way.

I'm no c++ guy, but you should be able to get the gist from this.

public static string Reverse(string s) {
    if (s == null || s.Length < 2) {
        return s;
    }

    int length = s.Length;
    int loop = (length >> 1) + 1;
    int j;
    char[] chars = new char[length];
    for (int i = 0; i < loop; i++) {
        j = length - i - 1;
        chars[i] = s[j];
        chars[j] = s[i];
    }
    return new string(chars);
}

I assume your game has a main loop, and all your sprites are in a list called sprites.

In your main loop, get all events, and check for the MOUSEBUTTONDOWN or MOUSEBUTTONUP event.

while ... # your main loop
  # get all events
  ev = pygame.event.get()

  # proceed events
  for event in ev:

    # handle MOUSEBUTTONUP
    if event.type == pygame.MOUSEBUTTONUP:
      pos = pygame.mouse.get_pos()

      # get a list of all sprites that are under the mouse cursor
      clicked_sprites = [s for s in sprites if s.rect.collidepoint(pos)]
      # do something with the clicked sprites...

So basically you have to check for a click on a sprite yourself every iteration of the mainloop. You'll want to use mouse.get_pos() and rect.collidepoint().

Pygame does not offer event driven programming, as e.g. cocos2d does.

Another way would be to check the position of the mouse cursor and the state of the pressed buttons, but this approach has some issues.

if pygame.mouse.get_pressed()[0] and mysprite.rect.collidepoint(pygame.mouse.get_pos()):
  print ("You have opened a chest!")

You'll have to introduce some kind of flag if you handled this case, since otherwise this code will print "You have opened a chest!" every iteration of the main loop.

handled = False

while ... // your loop

  if pygame.mouse.get_pressed()[0] and mysprite.rect.collidepoint(pygame.mouse.get_pos()) and not handled:
    print ("You have opened a chest!")
    handled = pygame.mouse.get_pressed()[0]

Of course you can subclass Sprite and add a method called is_clicked like this:

class MySprite(Sprite):
  ...

  def is_clicked(self):
    return pygame.mouse.get_pressed()[0] and self.rect.collidepoint(pygame.mouse.get_pos())

So, it's better to use the first approach IMHO.

Since this question is quite old, but still comes up in google searches, I thought it would be good to point out the newer (and recommended) way to save Keras models. Instead of saving them using the older h5 format like has been shown before, it is now advised to use the SavedModel format, which is actually a dictionary that contains both the model configuration and the weights.

More information can be found here: https://www.tensorflow.org/guide/keras/save_and_serialize

The snippets to save & load can be found below:

model.fit(test_input, test_target)
# Calling save('my_model') creates a SavedModel folder 'my_model'.
model.save('my_model')

# It can be used to reconstruct the model identically.
reconstructed_model = keras.models.load_model('my_model')

Indeed. The thing is that the 2008 R2 version is very tricky. The JTDs driver seems to work on some cases. In a certain server, the jTDS worked fine for an 2008 R2 instance. In another server, though, I had to use Microsoft's JBDC driver sqljdbc4.jar. But then, it would only work after setting the JRE environment to 1.6(or higher).

I used 1.5 for the other server, so I waisted a lot of time on this.

Tricky issue.

Separate classes by white space

$('element').removeClass('class1 class2');

Proxy: It is making the request on behalf of the client. So, the server will return the response to the proxy, and the proxy will forward the response to the client. In fact, the server will never "learn" who the client was (the client's IP address); it will only know the proxy. However, the client definitely knows the server, since it essentially formats the HTTP request destined for the server, but it just hands it to the proxy.

Reverse Proxy: It is receiving the request on behalf of the server. It forwards the request to the server, receives the response and then returns the response to the client. In this case, the client will never "learn" who was the actual server (the server's IP address) (with some exceptions); it will only know the proxy. The server will or won't know the actual client, depending on the configurations of the reverse proxy.

srand doesn't return anything so you can't initialize a with its return value because, well, because it doesn't return a value. Did you mean to call rand as well?

You could also use a list comprehension:

j = [l for l in i]

or make a copy of it using the statement:

j = i[:]

Updated code:

This is purported to work officially.

#if TARGET_IPHONE_SIMULATOR
NSString *hello = @"Hello, iPhone simulator!";
#elif TARGET_OS_IPHONE
NSString *hello = @"Hello, device!";
#else
NSString *hello = @"Hello, unknown target!";
#endif

This code will tell you if you are running in a simulator.

#ifdef __i386__
NSLog(@"Running in the simulator");

SharedPreferences are stored in an xml file in the app data folder, i.e.

/data/data/YOUR_PACKAGE_NAME/shared_prefs/YOUR_PREFS_NAME.xml

or the default preferences at:

/data/data/YOUR_PACKAGE_NAME/shared_prefs/YOUR_PACKAGE_NAME_preferences.xml

SharedPreferences added during runtime are not stored in the Eclipse project.

Note: Accessing /data/data/<package_name> requires superuser privileges

If anyone is still wondering what the value in CV_CAP_PROP_EXPOSURE might be:

Depends. For my cheap webcam I have to enter the desired value directly, e.g. 0.1 for 1/10s. For my expensive industrial camera I have to enter -5 to get an exposure time of 2^-5s = 1/32s.

That is why the new __dir__() method has been added in python 2.6

You should follow the guidelines on Add a secondary horizontal axis:

Add a secondary horizontal axis

To complete this procedure, you must have a chart that displays a secondary vertical axis. To add a secondary vertical axis, see Add a secondary vertical axis.

1. Click a chart that displays a secondary vertical axis. This displays the Chart Tools, adding the Design, Layout, and Format tabs.

2. On the Layout tab, in the Axes group, click Axes.

   

3. Click Secondary Horizontal Axis, and then click the display option that you want.

Add a secondary vertical axis

You can plot data on a secondary vertical axis one data series at a time. To plot more than one data series on the secondary vertical axis, repeat this procedure for each data series that you want to display on the secondary vertical axis.

1. In a chart, click the data series that you want to plot on a secondary vertical axis, or do the following to select the data series from a list of chart elements:

   • Click the chart.

     This displays the Chart Tools, adding the Design, Layout, and Format tabs.

   • On the Format tab, in the Current Selection group, click the arrow in the Chart Elements box, and then click the data series that you want to plot along a secondary vertical axis.

     

2. On the Format tab, in the Current Selection group, click Format Selection. The Format Data Series dialog box is displayed.

   Note: If a different dialog box is displayed, repeat step 1 and make sure that you select a data series in the chart.

3. On the Series Options tab, under Plot Series On, click Secondary Axis and then click Close.

   A secondary vertical axis is displayed in the chart.

4. To change the display of the secondary vertical axis, do the following:

   • On the Layout tab, in the Axes group, click Axes.

   • Click Secondary Vertical Axis, and then click the display option that you want.

5. To change the axis options of the secondary vertical axis, do the following:

   • Right-click the secondary vertical axis, and then click Format Axis.

   • Under Axis Options, select the options that you want to use.

Use ProcessBuilder to separate commands and arguments instead of spaces. This should work regardless of shell used:

import java.io.BufferedReader;
import java.io.File;
import java.io.IOException;
import java.io.InputStreamReader;
import java.util.ArrayList;
import java.util.List;

public class Test {

    public static void main(final String[] args) throws IOException, InterruptedException {
        //Build command 
        List<String> commands = new ArrayList<String>();
        commands.add("/bin/cat");
        //Add arguments
        commands.add("/home/narek/pk.txt");
        System.out.println(commands);

        //Run macro on target
        ProcessBuilder pb = new ProcessBuilder(commands);
        pb.directory(new File("/home/narek"));
        pb.redirectErrorStream(true);
        Process process = pb.start();

        //Read output
        StringBuilder out = new StringBuilder();
        BufferedReader br = new BufferedReader(new InputStreamReader(process.getInputStream()));
        String line = null, previous = null;
        while ((line = br.readLine()) != null)
            if (!line.equals(previous)) {
                previous = line;
                out.append(line).append('\n');
                System.out.println(line);
            }

        //Check result
        if (process.waitFor() == 0) {
            System.out.println("Success!");
            System.exit(0);
        }

        //Abnormal termination: Log command parameters and output and throw ExecutionException
        System.err.println(commands);
        System.err.println(out.toString());
        System.exit(1);
    }
}

If other solutions does not look good for some reason, you can still use this good old workaround of presenting with the delay of 0, like this:

dispatch_after(0, dispatch_get_main_queue(), ^{
    finishViewController *finished = [self.storyboard instantiateViewControllerWithIdentifier:@"finishViewController"];
    [self presentViewController:finished animated:NO completion:NULL];    
});

While I've seen no documented guarantee that your VC would be on the view hierarchy on the time dispatch block is scheduled to execution, I've observed it would work just fine.

Using delay of e.g. 0.2 sec is also an option. And the best thing - this way you don't need to mess with boolean variable in viewDidAppear:

You can use my libary called RDALogger. Here is github link.

With this library, you can log your message with method name/class name/line number and anchor link. With this link, when you click log, screen goes to this line of code.

To use library, you must do implementations below.

in root level gradle

allprojects {
        repositories {
            ...
            maven { url 'https://jitpack.io' }
        }
    }

in app level gradle

dependencies {
            implementation 'com.github.ardakaplan:RDALogger:1.0.0'
    }

For initializing library, you should start like this (in Application.class or before first use)

RDALogger.start("TAG NAME").enableLogging(true);

And than you can log whatever you want;

    RDALogger.info("info");
    RDALogger.debug("debug");
    RDALogger.verbose("verbose");
    RDALogger.warn("warn");
    RDALogger.error("error");
    RDALogger.error(new Throwable());
    RDALogger.error("error", new Throwable());

And finally output shows you all you want (class name, method name, anchor link, message)

08-09 11:13:06.023 20025-20025/com.ardakaplan.application I/Application: IN CLASS : (ENApplication.java:29)   ///   IN METHOD : onCreate
    info

data=np.genfromtxt(csv_file, delimiter=',', dtype='unicode')

It works fine for me.

Add "pscx" module

No, it isn't built into PowerShell. And the mklink utility cannot be called on its own on Windows Vista/Windows 7 because it is built directly into cmd.exe as an "internal command".

You can use the PowerShell Community Extensions (free). There are several cmdlets for reparse points of various types:

• New-HardLink,
• New-SymLink,
• New-Junction,
• Remove-ReparsePoint
• and others.

Frustratingly, you have to enable showing the dividers from code in your activity. For example:

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

    // Set the view to your layout
    setContentView(R.layout.yourlayout);

    // Find the LinearLayout within and enable the divider
    ((LinearLayout)v.findViewById(R.id.llTopBar)).
        setShowDividers(LinearLayout.SHOW_DIVIDER_MIDDLE);

}

You can't. It's not a trusted event.

Events that are generated by the user agent, either as a result of user interaction, or as a direct result of changes to the DOM, are trusted by the user agent with privileges that are not afforded to events generated by script through the DocumentEvent.createEvent("Event") method, modified using the Event.initEvent() method, or dispatched via the EventTarget.dispatchEvent() method. The isTrusted attribute of trusted events has a value of true, while untrusted events have a isTrusted attribute value of false.

Most untrusted events should not trigger default actions, with the exception of click or DOMActivate events.

You have to add a class and add/remove that on the mouseover/mouseout events manually.

Side note, I'm answering this here after I marked this as a duplicate since no answer here really covers the issue from what I see. Hopefully, one day it'll be merged.

Hello. I always have had some issues with the solutions above (and on other sites).
I, as a developer, am programming a addon for a API. The API prevents the use of any external libraries or 3rd party tools. The setup also consists of a mixture of code in jar or zip files and class files located directly in some directories. So my code had to be able to work arround every setup. After a lot of research I have come up with a method that will work in at least 95% of all possible setups.

The following code is basically the overkill method that will always work.

The code:

This code scans a given package for all classes that are included in it. It will only work for all classes in the current ClassLoader.

/**
 * Private helper method
 * 
 * @param directory
 *            The directory to start with
 * @param pckgname
 *            The package name to search for. Will be needed for getting the
 *            Class object.
 * @param classes
 *            if a file isn't loaded but still is in the directory
 * @throws ClassNotFoundException

private static void checkDirectory(File directory, String pckgname,
        ArrayList<Class<?>> classes) throws ClassNotFoundException {
    File tmpDirectory;

    if (directory.exists() && directory.isDirectory()) {
        final String[] files = directory.list();

        for (final String file : files) {
            if (file.endsWith(".class")) {
                try {
                    classes.add(Class.forName(pckgname + '.'
                            + file.substring(0, file.length() - 6)));
                } catch (final NoClassDefFoundError e) {
                    // do nothing. this class hasn't been found by the
                    // loader, and we don't care.
                }
            } else if ((tmpDirectory = new File(directory, file))
                    .isDirectory()) {
                checkDirectory(tmpDirectory, pckgname + "." + file, classes);

    return classes;
}

These three methods provide you with the ability to find all classes in a given package.
You use it like this:

getClassesForPackage("package.your.classes.are.in");

The explanation:

The method first gets the current ClassLoader. It then fetches all resources that contain said package and iterates of these URLs. It then creates a URLConnection and determines what type of URl we have. It can either be a directory (FileURLConnection) or a directory inside a jar or zip file (JarURLConnection). Depending on what type of connection we have two different methods will be called.

First lets see what happens if it is a FileURLConnection.
It first checks if the passed File exists and is a directory. If that's the case it checks if it is a class file. If so a Class object will be created and put in the ArrayList. If it is not a class file but is a directory, we simply iterate into it and do the same thing. All other cases/files will be ignored.

If the URLConnection is a JarURLConnection the other private helper method will be called. This method iterates over all Entries in the zip/jar archive. If one entry is a class file and is inside of the package a Class object will be created and stored in the ArrayList.

After all resources have been parsed it (the main method) returns the ArrayList containig all classes in the given package, that the current ClassLoader knows about.

If the process fails at any point a ClassNotFoundException will be thrown containg detailed information about the exact cause.

You will use the following query:

SELECT * FROM [table] GROUP BY NUMBER;

Where [table] is the name of the table.

This provides a unique listing for the NUMBER column however the other columns may be meaningless depending on the vendor implementation; which is to say they may not together correspond to a specific row or rows.

Consider you want to pass a custom attribute named myAttr with value myValue, this will work:

<MyComponent data-myAttr={myValue} />

You can use actual html tags <xmp> and </xmp> to output the string as is to show all of the tags in between the xmp tags.

Or you can also use on the server Server.UrlEncode or HttpUtility.HtmlEncode.

change PYTHONHOME to the parent folder of the bin file of python, like /usr,which is the parent folder of /usr/bin.

OK let's inspect some code.
File.java lines 428 to 435 in File.<init>:

String p = uri.getPath();
if (p.equals(""))
    throw new IllegalArgumentException("URI path component is empty");

// Okay, now initialize
p = fs.fromURIPath(p);
if (File.separatorChar != '/')
p = p.replace('/', File.separatorChar);

And let's read fs/*(FileSystem)*/.fromURIPath() docs:

java.io.FileSystem
public abstract String fromURIPath(String path)
Post-process the given URI path string if necessary. This is used on win32, e.g., to transform "/c:/foo" into "c:/foo". The path string still has slash separators; code in the File class will translate them after this method returns.

This means FileSystem.fromURIPath() does post processing on URI path only in Windows, and because in the next line:

p = p.replace('/', File.separatorChar);

It replaces each '/' with system dependent seperatorChar, you can always be sure that '/' is safe in every OS.

Object.keys(top_brands).forEach(function(key) {
  var value = top_brands[key];
  // use "key" and "value" here...
});

Btw, note that Object.keys and forEach are not available in ancient browsers, but you should use some polyfill anyway.

I trained a neural network in Keras to perform non linear regression on some data. This is some part of my code for testing on new data using previously saved model configuration and weights.

fname = r"C:\Users\tauseef\Desktop\keras\tutorials\BestWeights.hdf5"
modelConfig = joblib.load('modelConfig.pkl')
recreatedModel = Sequential.from_config(modelConfig)
recreatedModel.load_weights(fname)
unseenTestData = np.genfromtxt(r"C:\Users\tauseef\Desktop\keras\arrayOf100Rows257Columns.txt",delimiter=" ")
X_test = unseenTestData
standard_scalerX = StandardScaler()
standard_scalerX.fit(X_test)
X_test_std = standard_scalerX.transform(X_test)
X_test_std = X_test_std.astype('float32')
unseenData_predictions = recreatedModel.predict(X_test_std)

Wordpress uses MD5 Password hashing. Creates a hash of a plain text password. Unless the global $wp_hasher is set, the default implementation uses PasswordHash, which adds salt to the password and hashes it with 8 passes of MD5. MD5 is used by default because it's supported on all platforms. You can configure PasswordHash to use Blowfish or extended DES (if available) instead of MD5 with the $portable_hashes constructor argument or property.

select sys_context('USERENV','INSTANCE_NAME') from dual;

&

select instance_name from v$instance;

will give you the instance name. You can also use select * from global_name; to view the global name of the instance.

Speaking for the JS only solutions, I've found that, inelegant as it may be, a simple indexed for loop is more performant than its alternatives.

Extracting single property from a 100000 element array (via jsPerf)

Traditional for loop 368 Ops/sec

var vals=[];
for(var i=0;i<testArray.length;i++){
   vals.push(testArray[i].val);
}

ES6 for..of loop 303 Ops/sec

var vals=[];
for(var item of testArray){
   vals.push(item.val); 
}

Array.prototype.map 19 Ops/sec

var vals = testArray.map(function(a) {return a.val;});

TL;DR - .map() is slow, but feel free to use it if you feel readability is worth more than performance.

Edit #2: 6/2019 - jsPerf link broken, removed.

This is how I currently store a reference to the previous path in the $rootScope:

run(['$rootScope', function($rootScope) {
        $rootScope.$on('$locationChangeStart', function() {
            $rootScope.previousPage = location.pathname;
        });
}]);

An easy way of doing this:

SELECT  ('[' || to_json('Some "text"'::TEXT) || ']')::json ->> 0;

Just convert the json string into a json list

I encount this while I was calculating np.var(np.array([])). np.var will divide size of the array which is zero in this case.

I did what FD_ said and it crashed with errors as it was looking for "Landroid/support/v7/cardview/R$styleable;", which was not compiled with it

If you really want to use CardView before in eclipse before it gets its own library, you can extract the classes from the classes.jar, copy and paste them into your project, with the values.xml from above from Android Studio and change all the references to android.support.v7.R to yourpackagename.R in the copied classes. This worked and ran for me

The first step would be to add

position: 'absolute',

then if you want the element full width, add

left: 0,
right: 0,

then, if you want to put the element in the bottom, add

bottom: 0,
// don't need set top: 0

if you want to position the element at the top, replace bottom: 0 by top: 0

You also can use:

element.addEventListener("click", function(){
    // call execute function here...
}, false);

ConcurrentLinkedQueue is lock-free, LinkedBlockingQueue is not. Every time you invoke LinkedBlockingQueue.put() or LinkedBlockingQueue.take(), you need acquire the lock first. In other word, LinkedBlockingQueue has poor concurrency. If you care performance, try ConcurrentLinkedQueue + LockSupport.

Per https://developer.mozilla.org/en-US/docs/Web/API/WindowBase64/Base64_encoding_and_decoding and http://en.wikipedia.org/wiki/Basic_access_authentication , here is how to do Basic auth with a header instead of putting the username and password in the URL. Note that this still doesn't hide the username or password from anyone with access to the network or this JS code (e.g. a user executing it in a browser):

$.ajax({
  type: 'POST',
  url: http://theappurl.com/api/v1/method/,
  data: {},
  crossDomain: true,
  beforeSend: function(xhr) {
    xhr.setRequestHeader('Authorization', 'Basic ' + btoa(unescape(encodeURIComponent(YOUR_USERNAME + ':' + YOUR_PASSWORD))))
  }
});

SELECT Convert(varchar(10),CONVERT(date,'columnname',105),105) as "end";

OR

SELECT CONVERT(VARCHAR(10), CAST(event_enddate AS DATE), 105) AS [end];

will return the particular date in the format of 'dd-mm-yyyy'

The result would be like this..

04-07-2016

Maven will not run your tests if the project has <packaging>pom</packaging>

You need to set the packaging to jar (or some other java artefact type) for the tests to run: <packaging>jar</packaging>

MATLAB is a popular and widely adapted piece of a sophisticated software package. It'd be a mistake to think it's merely a math software since it has a wide range of "toolboxes". I recently used Matplotlib to plot some data from a database and it did the job without needing all the bells and whistles of MATLAB. However, it may not be proper to compare Python and MATLAB in every situation. As with everything else the decision depends on what you need to do.

I used MATLAB in undergrad for control systems design and simulation and also for image processing in grad school. For these fields MATLAB makes the most sense because of the powerful control and image processing toolboxes. As everyone mentioned, array operations, which are used in every MATLAB script you'd need to write, are very easy with MATLAB.

Another nice thing about MATLAB is that it's very easy and fast to do prototyping and trying out ideas using the built in toolbox functions. For instance, it takes no effort to import an image and compute it's histogram or do some simple processing on it. One disadvantage of MATLAB could be it's speed because of its interpreted nature. However, if one really needs speed than he can choose to implement the tested logic in C/C++, etc.

For further comparison with Python, I can say that MATLAB provides a full package for you to do your work without the need of looking around for external libraries and implementing extra functions.

One last point about MATLAB which I see is not mentioned in the answers here is that it has a very powerful visual modeling/simulation environment called Simulink. It's easier to design and simulate larger systems with Simulink.

Finally, again, it all depends on the problem you need to solve. If your problem domain can make use of one of MATLAB's toolboxes and you have access to MATLAB then you can be sure that you'll have the right tool to solve it.

I got this on Firefox (FF58). I fixed this with:

1. It is still experimental on Firefox (from v54): You have to set to true the variable dom.moduleScripts.enabled in about:config

Source: Import page on mozilla (See Browser compatibility)

2. Add type="module" to your script tag where you import the js file

<script type="module" src="appthatimports.js"></script>

3. Import files have to be prefixed (./, /, ../ or http:// before)

import * from "./mylib.js"

For more examples, this blog post is good.

I'm pretty sure you can completely delete the <stuff> , which will generate a warning and you can use an, @ suppress warnings. If you really want it to be generic, but to use any of its elements you will have to do type casting. For instance, I made a simple bubble sort function and it uses a generic type when sorting the list, which is actually an array of Comparable in this case. If you wish to use an item, do something like: System.out.println((Double)arrayOfDoubles[0] + (Double)arrayOfDoubles[1]); because I stuffed Double(s) into Comparable(s) which is polymorphism since all Double(s) inherit from Comparable to allow easy sorting through Collections.sort()

        //INDENT TO DISPLAY CODE ON STACK-OVERFLOW
@SuppressWarnings("unchecked")
public static void simpleBubbleSort_ascending(@SuppressWarnings("rawtypes") Comparable[] arrayOfDoubles)
{
//VARS
    //looping
    int end      =      arrayOfDoubles.length - 1;//the last index in our loops
    int iterationsMax = arrayOfDoubles.length - 1;

    //swapping
    @SuppressWarnings("rawtypes")
    Comparable tempSwap = 0.0;//a temporary double used in the swap process
    int elementP1 = 1;//element + 1,   an index for comparing and swapping


//CODE
    //do up to 'iterationsMax' many iterations
    for (int iteration = 0; iteration < iterationsMax; iteration++)
    {
        //go through each element and compare it to the next element
        for (int element = 0; element < end; element++)
        {
            elementP1 = element + 1;

            //if the elements need to be swapped, swap them
            if (arrayOfDoubles[element].compareTo(arrayOfDoubles[elementP1])==1)
            {
                //swap
                tempSwap = arrayOfDoubles[element];
                arrayOfDoubles[element] = arrayOfDoubles[elementP1];
                arrayOfDoubles[elementP1] = tempSwap;
            }
        }
    }
}//END public static void simpleBubbleSort_ascending(double[] arrayOfDoubles)

Express makes this kind of stuff really intuitive. The syntax looks like below :

var app = require('express').createServer();
app.get("/string", function(req, res) {
    var strings = ["rad", "bla", "ska"]
    var n = Math.floor(Math.random() * strings.length)
    res.send(strings[n])
})
app.listen(8001)

https://expressjs.com

If you're using jQuery on the client side you can do something like this:

$.get("/string", function(string) {
    alert(string)
})

The problem here is that you are trying to await an array of promises rather than a promise. This doesn't do what you expect.

When the object passed to await is not a Promise, await simply returns the value as-is immediately instead of trying to resolve it. So since you passed await an array (of Promise objects) here instead of a Promise, the value returned by await is simply that array, which is of type Promise<number>[].

What you need to do here is call Promise.all on the array returned by map in order to convert it to a single Promise before awaiting it.

According to the MDN docs for Promise.all:

The Promise.all(iterable) method returns a promise that resolves when all of the promises in the iterable argument have resolved, or rejects with the reason of the first passed promise that rejects.

So in your case:

var arr = [1, 2, 3, 4, 5];

var results: number[] = await Promise.all(arr.map(async (item): Promise<number> => {
    await callAsynchronousOperation(item);
    return item + 1;
}));

This will resolve the specific error you are encountering here.

I haven't had much luck with any of the answers on this page, however, below seemed to do the trick.

Add a server.js file with the following content:

const express = require('express')
const path = require('path')
const port = process.env.PORT || 3000
const app = express()

// serve static assets normally
app.use(express.static(__dirname + '/dist'))

// handle every other route with index.html, which will contain
// a script tag to your application's JavaScript file(s).
app.get('*', function (request, response){
  response.sendFile(path.resolve(__dirname, 'dist', 'index.html'))
})

app.listen(port)
console.log("server started on port " + port)

Also make sure that you require express. Run yarn add express --save or npm install express --save depending on your setup (I can recommend yarn it's pretty fast).

You may change dist to whatever folder you are serving your content is. For my simple project, I wasn't serving from any folder, so I simply removed the dist filename.

Then you may run node server.js. As I had to upload my project to a Heroku server, I needed to add the following to my package.json file:

  "scripts": {
    "start": "node server.js"
  }

Like the comments suggest, the solution is to use nested spans/rows.

<div class="container">
    <div class="row">
        <div class="span4">1</div>
        <div class="span8">
            <div class="row">
                <div class="span4">2</div>
                <div class="span4">3</div>
            </div>
            <div class="row">
                <div class="span4">4</div>
                <div class="span4">5</div>
            </div>
        </div>
    </div>
    <div class="row">
        <div class="span4">6</div>
        <div class="span4">7</div>
        <div class="span4">8</div>
    </div>
</div>

The easiest way is to make the "button image" as a separate image. Then place it over the main image (using "style="position: absolute;". Assign the URL link to "button image". and smile :)

On my system, I don't have the rename command. Here is a simple one liner. It finds all the HTML files recursively and adds prefix_ in front of their names:

for f in $(find . -name '*.html'); do mv "$f" "$(dirname "$f")/prefix_$(basename "$f")"; done

If you are trying to only serialize then pprint may also be a good option. It requires the object to be serialized and a file stream.

Here's some code:

from pprint import pprint
my_dict = {1:'a',2:'b'}
with open('test_results.txt','wb') as f:
    pprint(my_dict,f)

I am not sure if we can deserialize easily. I was using json to serialize and deserialze earlier which works correctly in most cases.

f.write(json.dumps(my_dict, sort_keys = True, indent = 2, ensure_ascii=True))

However, in one particular case, there were some errors writing non-unicode data to json.

Make sure the user has a localhost entry in the users table. That was the problem I was having. EX:

CREATE USER 'username'@'localhost' IDENTIFIED BY 'password';

I had a similar question, so I worked up a complete runnable answer below. What I needed to do is pass a class (C) to an object (O) of an unrelated class and have that object (O) emit new objects of class (C) back to me when I asked for them.

The example below shows how this is done. There is a MagicGun class that you load with any subtype of the Projectile class (Pebble, Bullet or NuclearMissle). The interesting is you load it with subtypes of Projectile, but not actual objects of that type. The MagicGun creates the actual object when it's time to shoot.

The Output

You've annoyed the target!
You've holed the target!
You've obliterated the target!
click

Your import has a subtle error:

import java.awt.List;

It should be:

import java.util.List;

The problem is that both awt and Java's util package provide a class called List. The former is a display element, the latter is a generic type used with collections. Furthermore, java.util.ArrayList extends java.util.List, not java.awt.List so if it wasn't for the generics, it would have still been a problem.

Edit: (to address further questions given by OP) As an answer to your comment, it seems that there is anther subtle import issue.

import org.omg.DynamicAny.NameValuePair;

should be

import org.apache.http.NameValuePair

nameValuePairs now uses the correct generic type parameter, the generic argument for new UrlEncodedFormEntity, which is List<? extends NameValuePair>, becomes valid, since your NameValuePair is now the same as their NameValuePair. Before, org.omg.DynamicAny.NameValuePair did not extend org.apache.http.NameValuePair and the shortened type name NameValuePair evaluated to org.omg... in your file, but org.apache... in their code.

Make sure you have the prerequisite, a JVM (http://wiki.eclipse.org/Eclipse/Installation#Install_a_JVM) installed.

This will be a JRE and JDK package.

There are a number of sources which includes: http://www.oracle.com/technetwork/java/javase/downloads/index.html.

Use backticks for system commands, which helps to store their results into Perl variables.

my $pid = 5892;
my $not = ``top -H -p $pid -n 1 | grep myprocess | wc -l`; 
print "not = $not\n";

INSERT INTO prices(group, id, price)
SELECT 7, articleId, 1.50
FROM article where name like 'ABC%';

Try this:

string fileName = Path.GetFileNameWithoutExtension(@"C:\Program Files\hello.txt");

This will return "hello" for fileName.

Tagging of the image isn't supported inside the Dockerfile. This needs to be done in your build command. As a workaround, you can do the build with a docker-compose.yml that identifies the target image name and then run a docker-compose build. A sample docker-compose.yml would look like

version: '2'

services:
  man:
    build: .
    image: dude/man:v2

That said, there's a push against doing the build with compose since that doesn't work with swarm mode deploys. So you're back to running the command as you've given in your question:

docker build -t dude/man:v2 .

Personally, I tend to build with a small shell script in my folder (build.sh) which passes any args and includes the name of the image there to save typing. And for production, the build is handled by a ci/cd server that has the image name inside the pipeline script.

If you are using Apache place a .htaccess file in your root web directory containing the following:

RewriteEngine on
RewriteCond $1 !^(index\.php|[Javascript / CSS / Image root Folder name(s)]|robots\.txt)
RewriteRule ^(.*)$ /index.php/$1 [L]

EDIT: look at this answer. Using np.cumsum is much faster than np.convolve

A quick and dirty way to smooth data I use, based on a moving average box (by convolution):

x = np.linspace(0,2*np.pi,100)
y = np.sin(x) + np.random.random(100) * 0.8

def smooth(y, box_pts):
    box = np.ones(box_pts)/box_pts
    y_smooth = np.convolve(y, box, mode='same')
    return y_smooth

plot(x, y,'o')
plot(x, smooth(y,3), 'r-', lw=2)
plot(x, smooth(y,19), 'g-', lw=2)

I think you need to run that .msi to install the dlls. After I ran that .msi I can go to (VS 2012) Add References > Assemblies > Extensions and all of the Microsoft.Office.Interop dlls are there.

On my computer the dlls are found in "c:\Program Files(x86)\Microsoft Visual Studio 12.0\Visual Studio Tools for Office\PIA" so you could check in a similar/equivalent directory on yours just to make sure they're not there?

The following will give you the hex encoding for the low byte of each character, which looks like what you're asking for:

StringBuilder sb = new StringBuilder();
foreach (char c in asciiString)
{
    uint i = (uint)c;
    sb.AppendFormat("{0:X2}", (i & 0xff));
}
return sb.ToString();

My advice is to use a library. There are several available at pypi.org.

I use this one, it it works good: https://pypi.python.org/pypi/asjson

You can code like two input box inside one div

<div class="input-group">
            <span class="input-group-addon"><i class="glyphicon glyphicon-user"></i></span>
            <input style="width:50% " class="form-control " placeholder="first name"  name="firstname" type="text" />
            <input style="width:50% " class="form-control " placeholder="lastname"  name="lastname" type="text" />
        </div>

There is no built-in date-only type in .NET.

The convention is to use a DateTime with the time portion set to midnight.

The static DateTime.Today property will give you today's date.

In redux-saga, the equivalent of the above example would be

export function* loginSaga() {
  while(true) {
    const { user, pass } = yield take(LOGIN_REQUEST)
    try {
      let { data } = yield call(request.post, '/login', { user, pass });
      yield fork(loadUserData, data.uid);
      yield put({ type: LOGIN_SUCCESS, data });
    } catch(error) {
      yield put({ type: LOGIN_ERROR, error });
    }  
  }
}

export function* loadUserData(uid) {
  try {
    yield put({ type: USERDATA_REQUEST });
    let { data } = yield call(request.get, `/users/${uid}`);
    yield put({ type: USERDATA_SUCCESS, data });
  } catch(error) {
    yield put({ type: USERDATA_ERROR, error });
  }
}

The first thing to notice is that we're calling the api functions using the form yield call(func, ...args). call doesn't execute the effect, it just creates a plain object like {type: 'CALL', func, args}. The execution is delegated to the redux-saga middleware which takes care of executing the function and resuming the generator with its result.

The main advantage is that you can test the generator outside of Redux using simple equality checks

const iterator = loginSaga()

assert.deepEqual(iterator.next().value, take(LOGIN_REQUEST))

// resume the generator with some dummy action
const mockAction = {user: '...', pass: '...'}
assert.deepEqual(
  iterator.next(mockAction).value, 
  call(request.post, '/login', mockAction)
)

// simulate an error result
const mockError = 'invalid user/password'
assert.deepEqual(
  iterator.throw(mockError).value, 
  put({ type: LOGIN_ERROR, error: mockError })
)

Note we're mocking the api call result by simply injecting the mocked data into the next method of the iterator. Mocking data is way simpler than mocking functions.

The second thing to notice is the call to yield take(ACTION). Thunks are called by the action creator on each new action (e.g. LOGIN_REQUEST). i.e. actions are continually pushed to thunks, and thunks have no control on when to stop handling those actions.

In redux-saga, generators pull the next action. i.e. they have control when to listen for some action, and when to not. In the above example the flow instructions are placed inside a while(true) loop, so it'll listen for each incoming action, which somewhat mimics the thunk pushing behavior.

The pull approach allows implementing complex control flows. Suppose for example we want to add the following requirements

• Handle LOGOUT user action

• upon the first successful login, the server returns a token which expires in some delay stored in a expires_in field. We'll have to refresh the authorization in the background on each expires_in milliseconds

• Take into account that when waiting for the result of api calls (either initial login or refresh) the user may logout in-between.

How would you implement that with thunks; while also providing full test coverage for the entire flow? Here is how it may look with Sagas:

function* authorize(credentials) {
  const token = yield call(api.authorize, credentials)
  yield put( login.success(token) )
  return token
}

function* authAndRefreshTokenOnExpiry(name, password) {
  let token = yield call(authorize, {name, password})
  while(true) {
    yield call(delay, token.expires_in)
    token = yield call(authorize, {token})
  }
}

function* watchAuth() {
  while(true) {
    try {
      const {name, password} = yield take(LOGIN_REQUEST)

      yield race([
        take(LOGOUT),
        call(authAndRefreshTokenOnExpiry, name, password)
      ])

      // user logged out, next while iteration will wait for the
      // next LOGIN_REQUEST action

    } catch(error) {
      yield put( login.error(error) )
    }
  }
}

In the above example, we're expressing our concurrency requirement using race. If take(LOGOUT) wins the race (i.e. user clicked on a Logout Button). The race will automatically cancel the authAndRefreshTokenOnExpiry background task. And if the authAndRefreshTokenOnExpiry was blocked in middle of a call(authorize, {token}) call it'll also be cancelled. Cancellation propagates downward automatically.

You can find a runnable demo of the above flow

I had the same issue in 14.04, but I fixed it by these steps:

1. sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 7F0CEB10
2. echo "deb http://repo.mongodb.org/apt/ubuntu "$(lsb_release -sc)"/mongodb- org/3.0 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-3.0.list
3. sudo apt-get update
4. sudo apt-get install -y mongodb

It worked like charm :)

You need to access the matches in order to get at the SDI number. Here is a function that will do it (assuming there is only 1 SDI number per cell).

For the regex, I used "sdi followed by a space and one or more numbers". You had "sdi followed by a space and zero or more numbers". You can simply change the + to * in my pattern to go back to what you had.

Function ExtractSDI(ByVal text As String) As String

Dim result As String
Dim allMatches As Object
Dim RE As Object
Set RE = CreateObject("vbscript.regexp")

RE.pattern = "(sdi \d+)"
RE.Global = True
RE.IgnoreCase = True
Set allMatches = RE.Execute(text)

If allMatches.count <> 0 Then
    result = allMatches.Item(0).submatches.Item(0)
End If

ExtractSDI = result

End Function

If a cell may have more than one SDI number you want to extract, here is my RegexExtract function. You can pass in a third paramter to seperate each match (like comma-seperate them), and you manually enter the pattern in the actual function call:

Ex) =RegexExtract(A1, "(sdi \d+)", ", ")

Here is:

Function RegexExtract(ByVal text As String, _
                      ByVal extract_what As String, _
                      Optional seperator As String = "") As String

Dim i As Long, j As Long
Dim result As String
Dim allMatches As Object
Dim RE As Object
Set RE = CreateObject("vbscript.regexp")

RE.pattern = extract_what
RE.Global = True
Set allMatches = RE.Execute(text)

For i = 0 To allMatches.count - 1
    For j = 0 To allMatches.Item(i).submatches.count - 1
        result = result & seperator & allMatches.Item(i).submatches.Item(j)
    Next
Next

If Len(result) <> 0 Then
    result = Right(result, Len(result) - Len(seperator))
End If

RegexExtract = result

End Function

*Please note that I have taken "RE.IgnoreCase = True" out of my RegexExtract, but you could add it back in, or even add it as an optional 4th parameter if you like.

For apache-tomcat-8.5.28

modify JDPA_OPTS like the below then run like catalina.bat jpda start

JPDA_OPTS="-agentlib:jdwp=transport=$JPDA_TRANSPORT,address=$JPDA_ADDRESS,server=y,suspend=$JPDA_SUSPEND"
JPDA_OPTS="-agentlib:jdwp=transport=$JPDA_TRANSPORT,address=8000,server=y,suspend=$JPDA_SUSPEND"

The advantage of IEnumerable is deferred execution (usually with databases). The query will not get executed until you actually loop through the data. It's a query waiting until it's needed (aka lazy loading).

If you call ToList, the query will be executed, or "materialized" as I like to say.

There are pros and cons to both. If you call ToList, you may remove some mystery as to when the query gets executed. If you stick to IEnumerable, you get the advantage that the program doesn't do any work until it's actually required.

You can style the button using CSS or use an image-input. Additionally you might use the button element which supports inline content.

<button type="submit"><img src="/path/to/image" alt="Submit"></button>

Fix it by install metro-config of the latest version (0.57.0 for now) they had fixed the problem:

npm install metro-config

you can remove it later, after react-native guys update module versions

Yes, you can do a 3 table join for an update statement. Here is an example :

    UPDATE customer_table c 

      JOIN  
          employee_table e
          ON c.city_id = e.city_id  
      JOIN 
          anyother_ table a
          ON a.someID = e.someID

    SET c.active = "Yes"

    WHERE c.city = "New york";

Someone asked about adding attributes (specifically, 'rows' and 'cols'). If you're using Razor, you could just do this:

@Html.TextAreaFor(model => model.Text, new { cols = 35, @rows = 3 })

That works for me. The '@' is used to escape keywords so they are treated as variables/properties.

I had also similar problem. In my case brokerUrl was not configured properly. So that's way I received following Error:

Cause: Error While attempting to add new Connection to the pool: nested exception is javax.jms.JMSException: Could not connect to broker URL : tcp://localhost:61616. Reason: java.net.ConnectException: Connection refused

& I resolved it following way.

   ActiveMQConnectionFactory connectionFactory = new ActiveMQConnectionFactory();

  connectionFactory.setBrokerURL("tcp://hostname:61616");
  connectionFactory.setUserName("admin");
  connectionFactory.setPassword("admin");
