If you can't just limit the query itself with a where clause, you can use the fact that the count aggregate only counts the non-null values:

select count(case Position when 'Manager' then 1 else null end)
from ...

You can also use the sum aggregate in a similar way:

select sum(case Position when 'Manager' then 1 else 0 end)
from ...

Maybe you should try

^[#;].*$

^ matches the beggining, $ the end.

The Return View(model) returns you error because you don't fill the model with the values in your post method and the model data for the dropdown is empty. Please provide the Get method to explain further how to manage displaying the error. In order to the error to be shown you should use this:

[HttpPost]
public ActionResult form_edit(FormModels model)
{          
   if(ModelState.IsValid())
   {
      --- operations 
      return Redirect("OtherAction", "SomeController");
   }

   // here you can use a little trick
   //fill the model property that holds the information for the dropdown with the data 

   // you haven't provided the get method but it should look something like this
   model.Countries = ... some data goes here;
   model.dd_value = ... some other data;
   model.dd_text = ... other data;

   ModelState.AddModelError("", "adfdghdghgdhgdhdgda");
   return View(model);
}

and then in the view just use :

@model mvc_cs.Models.FormModels
@using ctrlr = mvc_cs.Controllers.FormController


@using (Html.BeginForm("form_edit", "Form", FormMethod.Post))
{

    <table>
    <tr>
    <td>       
    @Html.ValidationSummary(true)             
    </td>
    </tr>
<tr>
    <th>
        @Html.DisplayNameFor(model => model.content_name)
        @Html.DropDownListFor(x => x.selectedvalue, new SelectList(Model.Countries, Model.dd_value, Model.dd_text), "-- Select Product--")

    </th>
</tr>
</table>

<table>
<tr>
    <td>
        <input  type="submit" value="Submit" />
    </td>
</tr>
</table>
}

This should work okay.

If you just use RedirectToAction it will redirect you to the get method --> you will have no error but the view will be just reloaded and no error would be shown.

other way around is that you can pass the error not by ModelState.AddError, but with ViewData["error"] like this:

[HttpPost]
public ActionResult form_edit(FormModels model)
{          
   TempData["error"] = "someErrorMessage";
   return RedirectToAction("form_Post", "Form");
}

[HttpGet]
public ActionResult form_edit()
{
    do stuff here ----
    ViewData["error"] = TempData["error"];
    return View();
}

@model mvc_cs.Models.FormModels
@using ctrlr = mvc_cs.Controllers.FormController


@using (Html.BeginForm("form_edit", "Form", FormMethod.Post))
{

    <table>
    <tr>
    <td>       
    <div>@ViewData["error"]</div>             
    </td>
    </tr>
<tr>
    <th>
        @Html.DisplayNameFor(model => model.content_name)
        @Html.DropDownListFor(x => x.selectedvalue, new SelectList(Model.Countries, Model.dd_value, Model.dd_text), "-- Select Product--")

    </th>
</tr>
</table>

<table>
<tr>
    <td>
        <input  type="submit" value="Submit" />
    </td>
</tr>
</table>
}

Swift

if let url = NSURL(string: "tel://\(number)"), 
    UIApplication.sharedApplication().canOpenURL(url) {
        UIApplication.shared.open(url, options: [:], completionHandler: nil)
}

$array  = data();

print_r($array);

There are only two ways:

• If the memory pointer to by your char * represents a C string (that is, it contains characters that have a 0-byte to mark its end), you can use strlen(a).

• Otherwise, you need to store the length somewhere. Actually, the pointer only points to one char. But we can treat it as if it points to the first element of an array. Since the "length" of that array isn't known you need to store that information somewhere.

const myMap = new Map(
    Object
        .keys(myObj)
        .map(
            key => [key, myObj[key]]
        )
)

You can also convert your array to a list and call remove on the list. You can then convert back to your array.

int[] numbers = {1, 3, 4, 9, 2};
var numbersList = numbers.ToList();
numbersList.Remove(4);

can i just throw in that if you distort your images too much, ie take them out of a ratio, they may not look right, - a tiny amount is fine, but one way to do this is put the images inside a 'container' and set the container to the 100 x 100, then set your image to overflow none, and set the smallest width to the maximum width of the container, this will crop a bit of your image though,

for example

<h4>Products</h4>
<ul class="products">
    <li class="crop">
        <img src="ipod.jpg" alt="iPod" />
    </li>
</ul>



.crop {
 height: 300px;
 width: 400px;
 overflow: hidden;
}
.crop img {
 height: auto;
 width: 400px;
}

This way the image will stay the size of its container, but will resize without breaking constraints

There's no need, just use fadeToggle() on the element:

$('#testElement').fadeToggle('fast');

Here's a demo.

It is probably better to create a dedicated function to create the link so you can avoid creating two anonymous functions. Thus:

<div id="div"></div>

<script>
  function getLink(id)
  {
    var link = document.createElement('a');
    link.setAttribute('href', '#');
    link.innerHTML = id;
    link.onclick = function()
    {
      onClickLink(id);
    };
    link.style.display = 'block';
    return link;
  }
  var div = document.getElementById('div');
  for (var i = 0; i < 10; i += 1)
  {
    div.appendChild(getLink(i.toString()));
  }
</script>

Although in both cases you end up with two functions, I just think it is better to wrap it in a function that is semantically easier to comprehend.

Go to Efficient Editing with vim and learn what you need to get started. Not everything on that page is essential starting off, so cherry pick what you want.

From there, use vim for everything. "hjkl", "y", and "p" will get you a long way, even if it's not the most efficient way. When you come up against a task for which you don't know the magic key to do it efficiently (or at all), and you find yourself doing it more than a few times, go look it up. Little by little it will become second nature.

I found vim daunting many moons ago (back when it didn't have the "m" on the end), but it only took about a week of steady use to get efficient. I still find it the quickest editor in which to get stuff done.

You can use:

if [ 1 -eq 0 ]; then
  echo "The code that you want commented out goes here."
  echo "This echo statement will not be called."

I have worked with SSRS for over 10 years and the answers above are the go to answers. BUT. If nothing works, and you are completely stuffed....remove items from the report until the problem goes away. Once you have identified which row or report item is causing the problem, put it inside a rectangle container. That's it. Has helped us many many times! Extra pages are mostly caused by report items flowing over the right margin. When all else fails, putting things inside a rectangle or an empty rectangle to the right of an item, can stop this from happening. Good luck out there!

Solution is very Simple, put the following lines into your style.xml

For dark mode:

<item name="android:windowLightStatusBar">false</item>
<item name="android:statusBarColor">@color/black</item>

Make an /login url, than accept "user" and "password" parameters via GET and don't require basic auth. Here, use php, node, java, whatever and parse your passwd file and match parameters (user/pass) against it. If there is a match then redirect to http://user:[email protected]/ (this will set credential on your browser) if not, send 401 response (without WWW-Authenticate header).

For Intellij IDEA type sout and press Tab.

For Eclipse type syso and press Ctrl+Space.

I know this has been answered a lot of times, but here are my two cents to the issue.

I found the answers by samvermette and ribeto really useful, and also the comment by maxpower in the ribeto's answer. But there is a problem with those approaches. The problem that matt mentions in the samvermette's answer and it's that if the user wants to paste something with a line break inside it, the keyboard would hide without pasting anything.

So my approach is a mixture of the three above mentioned solutions and only checking if the string entered is a new line when the length of the string is 1 so we make sure the user is typing instead of pasting.

Here is what I have done:

- (BOOL)textView:(UITextView *)textView shouldChangeTextInRange:(NSRange)range replacementText:(NSString *)text {
    NSRange resultRange = [text rangeOfCharacterFromSet:[NSCharacterSet newlineCharacterSet] options:NSBackwardsSearch];
    if ([text length] == 1 && resultRange.location != NSNotFound) {
        [textView resignFirstResponder];
        return NO;
    }

    return YES;
}

Not sure what the author of that code wanted to achieve. Definining a function inside another function does NOT mean that the inner function is only visible inside the outer function. After calling x() the first time, the y() function will be in global scope as well.

As other answers note, the correct way to find the Java home directory is to use /usr/libexec/java_home.

The official documentation for this is in Apple's Technical Q&A QA1170: Important Java Directories on OS X: https://developer.apple.com/library/mac/qa/qa1170/_index.html

I guess you should add android:centerColor

<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<gradient
  android:startColor="#FFFFFF"
  android:centerColor="#000000"
  android:endColor="#FFFFFF"
  android:angle="0" />
</shape>

This example displays a horizontal gradient from white to black to white.

The problem must be with the value Model.Id which is null. You can confirm by assigning a value, e.g

@{         
     var blogPostId = 1;          
 }

If the error disappers, then u need to make sure that your model Id has a value before passing it to the view

According to this article, if you would like to have the same precision of DateTime using DateTime2 you simply have to use DateTime2(3). This should give you the same precision, take up one fewer bytes, and provide an expanded range.

using (SqlConnection connection =  new SqlConnection("Data Source=localhost;Initial Catalog=LoginScreen;Integrated Security=True"))
{
    SqlCommand command =
    new SqlCommand("select * from Pending_Tasks WHERE CustomerId=...", connection);
    connection.Open();

    SqlDataReader read= command.ExecuteReader();

    while (read.Read())
    {
        CustID.Text = (read["Customer_ID"].ToString());
        CustName.Text = (read["Customer_Name"].ToString());
        Add1.Text = (read["Address_1"].ToString());
        Add2.Text = (read["Address_2"].ToString());
        PostBox.Text = (read["Postcode"].ToString());
        PassBox.Text = (read["Password"].ToString());
        DatBox.Text = (read["Data_Important"].ToString());
        LanNumb.Text = (read["Landline"].ToString());
        MobNumber.Text = (read["Mobile"].ToString());
        FaultRep.Text = (read["Fault_Report"].ToString());
    }
    read.Close();
}

Make sure you have data in the query : select * from Pending_Tasks and you are using "using System.Data.SqlClient;"

I had a the same error and solved it after moving initialization of formBuilder from ngOnInit to constructor.

I would suggest to use ExpectedConditions and alertIsPresent(). ExpectedConditions is a wrapper class that implements useful conditions defined in ExpectedCondition interface.

public boolean isAlertPresent(){
    boolean foundAlert = false;
    WebDriverWait wait = new WebDriverWait(driver, 0 /*timeout in seconds*/);
    try {
        wait.until(ExpectedConditions.alertIsPresent());
        foundAlert = true;
    } catch (TimeoutException eTO) {
        foundAlert = false;
    }
    return foundAlert;
}

Note: this is based on the answer by nilesh, but adapted to catch the TimeoutException which is thrown by the wait.until() method.

There are a lot of 365.25 answers here. Remember how leap years are defined:

• Every four years
  • except every 100 years
    • except every 400 years

ALTER TABLE <tablename> CHANGE COLUMN <colname> <colname> VARCHAR(65536);

You have to list the column name twice, even if you aren't changing its name.

Note that after you make this change, the data type of the column will be MEDIUMTEXT.

Miky D is correct, the MODIFY command can do this more concisely.

Re the MEDIUMTEXT thing: a MySQL row can be only 65535 bytes (not counting BLOB/TEXT columns). If you try to change a column to be too large, making the total size of the row 65536 or greater, you may get an error. If you try to declare a column of VARCHAR(65536) then it's too large even if it's the only column in that table, so MySQL automatically converts it to a MEDIUMTEXT data type.

mysql> create table foo (str varchar(300));
mysql> alter table foo modify str varchar(65536);
mysql> show create table foo;
CREATE TABLE `foo` (
  `str` mediumtext
) ENGINE=MyISAM DEFAULT CHARSET=latin1
1 row in set (0.00 sec)

I misread your original question, you want VARCHAR(65353), which MySQL can do, as long as that column size summed with the other columns in the table doesn't exceed 65535.

mysql> create table foo (str1 varchar(300), str2 varchar(300));
mysql> alter table foo modify str2 varchar(65353);
ERROR 1118 (42000): Row size too large. 
The maximum row size for the used table type, not counting BLOBs, is 65535. 
You have to change some columns to TEXT or BLOBs

A great way to learn more about anything (any function) is to remember that everything is a function! That general mantra helps, but in specific cases like operators, it helps to remember this little trick:

:t (.)
(.) :: (b -> c) -> (a -> b) -> a -> c

and

:t ($)
($) :: (a -> b) -> a -> b

Just remember to use :t liberally, and wrap your operators in ()!

Set the g modifier for a global match:

/…/g

Using the stat.* bit masks does seem to me the most portable and explicit way of doing this. But on the other hand, I often forget how best to handle that. So, here's an example of masking out the 'group' and 'other' permissions and leaving 'owner' permissions untouched. Using bitmasks and subtraction is a useful pattern.

import os
import stat
def chmodme(pn):
    """Removes 'group' and 'other' perms. Doesn't touch 'owner' perms."""
    mode = os.stat(pn).st_mode
    mode -= (mode & (stat.S_IRWXG | stat.S_IRWXO))
    os.chmod(pn, mode)

After changing language newly created activities display with changed new language, but current activity and previously created activities which are in pause state are not updated.How to update activities ?

Pre API 11 (Honeycomb), the simplest way to make the existing activities to be displayed in new language is to restart it. In this way you don't bother to reload each resources by yourself.

private void restartActivity() {
    Intent intent = getIntent();
    finish();
    startActivity(intent);
}

Register an OnSharedPreferenceChangeListener, in its onShredPreferenceChanged(), invoke restartActivity() if language preference was changed. In my example, only the PreferenceActivity is restarted, but you should be able to restart other activities on activity resume by setting a flag.

Update (thanks @stackunderflow): As of API 11 (Honeycomb) you should use recreate() instead of restartActivity().

public class PreferenceActivity extends android.preference.PreferenceActivity implements
        OnSharedPreferenceChangeListener {

    // ...

    @Override
    public void onSharedPreferenceChanged(SharedPreferences sharedPreferences, String key) {
        if (key.equals("pref_language")) {
            ((Application) getApplication()).setLocale();
            restartActivity();
        }
    }

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        addPreferencesFromResource(R.xml.preferences);
        getPreferenceScreen().getSharedPreferences().registerOnSharedPreferenceChangeListener(this);
    }

    @Override
    protected void onStop() {
        super.onStop();
        getPreferenceScreen().getSharedPreferences().unregisterOnSharedPreferenceChangeListener(this);
    }
}

I have a blog post on this topic with more detail, but it's in Chinese. The full source code is on github: PreferenceActivity.java

Can't get exactly what you are asking but if you are using an aggregate SUM function which implies that you are grouping the table.

The query goes for MYSQL like this

Select IFNULL(SUM(COLUMN1),0) as total from mytable group by condition

The answers on here are specific to using the custom UI Editor. I spent some time creating the interface without that wonderful program, so I am documenting the solution here to help anyone else decide if they need that custom UI editor or not.

I came across the following microsoft help webpage - https://msdn.microsoft.com/en-us/library/office/ff861787.aspx. This shows how to set up the interface manually, but I had some trouble when pointing to my custom add-in code.

To get the buttons to work with your custom macros, setup the macro in your .xlam subs to be called as described in this SO answer - Calling an excel macro from the ribbon. Basically, you'll need to add that "control As IRibbonControl" paramter to any module pointed from your ribbon xml. Also, your ribbon xml should have the onAction="myaddin!mymodule.mysub" syntax to properly call any modules loaded by the add in.

Using those instructions I was able to create an excel add in (.xlam file) that has a custom tab loaded when my VBA gets loaded into Excel along with the add in. The buttons execute code from the add in and the custom tab uninstalls when I remove the add in.

The .title() method won't work in all test cases, so using .capitalize(), .replace() and .split() together is the best choice to capitalize the first letter of each word.

eg: def caps(y):

     k=y.split()
     for i in k:
        y=y.replace(i,i.capitalize())
     return y

The problem is autofill is handled differently by different browsers. Some dispatch the change event, some don't. So it is almost impossible to hook onto an event which is triggered when browser autocompletes an input field.

• Change event trigger for different browsers:

  • For username/password fields:

    1. Firefox 4, IE 7, and IE 8 don't dispatch the change event.
    2. Safari 5 and Chrome 9 do dispatch the change event.

  • For other form fields:

    1. IE 7 and IE 8 don't dispatch the change event.
    2. Firefox 4 does dispatch the change change event when users select a value from a list of suggestions and tab out of the field.
    3. Chrome 9 does not dispatch the change event.
    4. Safari 5 does dispatch the change event.

You best options are to either disable autocomplete for a form using autocomplete="off" in your form or poll at regular interval to see if its filled.

For your question on whether it is filled on or before document.ready again it varies from browser to browser and even version to version. For username/password fields only when you select a username password field is filled. So altogether you would have a very messy code if you try to attach to any event.

You can have a good read on this HERE

You could use string.Join:

List<string> list = new List<string>()
{
    "Red",
    "Blue",
    "Green"
};

string output = string.Join(Environment.NewLine, list.ToArray());    
Console.Write(output);

The result would be:

Red    
Blue    
Green

As an alternative to Environment.NewLine, you can replace it with a string based line-separator of your choosing.

Rounded Button Demo Examples on DartPad

if you do not intend to have static functions just get rid of the "this" keyword in the arguments.

If your targetSdkVersion is 24 or higher, you can not use file: Uri values in Intents on Android 7.0+ devices.

Your choices are:

1. Drop your targetSdkVersion to 23 or lower, or

2. Put your content on internal storage, then use FileProvider to make it available selectively to other apps

For example:

Intent i=new Intent(Intent.ACTION_VIEW, FileProvider.getUriForFile(this, AUTHORITY, f));

i.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
startActivity(i);

(from this sample project)

This is most probably an encoding error. For example I had an xml file encoded in UTF-8-BOM (checked from the Notepad++ Encoding menu) and got similar error message.

The workaround (Python 3.6)

import io
from xml.etree import ElementTree as ET

with io.open(file, 'r', encoding='utf-8-sig') as f:
    contents = f.read()
    tree = ET.fromstring(contents)

Check the encoding of your xml file. If it is using different encoding, change the 'utf-8-sig' accordingly.

In order to avoid to pass this argument i use class derived from Application

public class MyApplication extends Application {

private static Context sContext;

@Override
public void onCreate() {
    super.onCreate();
    sContext=   getApplicationContext();

}

public static Context getContext() {
    return sContext;
}

and invoke MyApplication.getContext() in Helper classes.

Don't forget to update the manifest.

<?xml version="1.0" encoding="utf-8"?> 
<manifest xmlns:android="http://schemas.android.com/apk/res/android" 
package="com.example"> 
      <application 
       android:name=".MyApplication"
       android:allowBackup="true" 
       android:icon="@mipmap/ic_launcher" 
       android:label="@string/app_name"> 
         <activity....>
            ......
         </activity>
     </application> 
</manifest>

I find it disturbing that the word 'cohesion' does not appear anywhere in these posts (until now). And I'm also disturbed that anyone thinks enabling or encouraging huge classes and methods is somehow a good thing. If you're trying to understand and maintain a code-base 'partial' sucks.

Here is bitmap extension .convertToByteArray wrote in Kotlin.

/**
 * Convert bitmap to byte array using ByteBuffer.
 */
fun Bitmap.convertToByteArray(): ByteArray {
    //minimum number of bytes that can be used to store this bitmap's pixels
    val size = this.byteCount

    //allocate new instances which will hold bitmap
    val buffer = ByteBuffer.allocate(size)
    val bytes = ByteArray(size)

    //copy the bitmap's pixels into the specified buffer
    this.copyPixelsToBuffer(buffer)

    //rewinds buffer (buffer position is set to zero and the mark is discarded)
    buffer.rewind()

    //transfer bytes from buffer into the given destination array
    buffer.get(bytes)

    //return bitmap's pixels

You can't do regular ping in browser Javascript, but you can find out if remote server is alive by for example loading an image from the remote server. If loading fails -> server down.

You can even calculate the loading time by using onload-event. Here's an example how to use onload event.

You just have to define the property below inside the activity element in your AndroidManifest.xml file. It will restrict your orientation to portrait.

android:screenOrientation="portrait"

Example:

        <activity
            android:name="com.example.demo_spinner.MainActivity"
            android:label="@string/app_name"
            android:screenOrientation="portrait" >
        </activity>

if you want this to apply to the whole app define the property below inside the application tag like so:

        <application>
         android:screenOrientation="sensorPortrait"
        </application>

Additionaly, as per Eduard Luca's comment below, you can also use screenOrientation="sensorPortrait" if you want to enable rotation by 180 degrees.

Fundamentally you hadn't declare location which is what nginx uses to bind URL with resources.

 server {
            listen       80;
            server_name  localhost;

            access_log  logs/localhost.access.log  main;

            location / {
                root /var/www/board/public;
                index index.html index.htm index.php;
            }
       }

You code should be:

   <section id="right">
      <label for="form_msg">Message</label>
      <textarea name="form_msg" id="#msg_text"></textarea>
      <input id="submit" class="button" name="submit" type="submit" value="Send">
   </section>

Js

var data = {
    name: $("#form_name").val(),
    email: $("#form_email").val(),
    message: $("#msg_text").val()
};
$.ajax({
    type: "POST",
    url: "email.php",
    data: data,
    success: function(){
        $('.success').fadeIn(1000);
    }
});

The PHP:

<?php
if($_POST){
    $name = $_POST['name'];
    $email = $_POST['email'];
    $message = $_POST['text'];

//send email
    mail("[email protected]","My Subject:",$email,$message);
}
?>

Example for the first point by dlaliberte:

A closure is not only created when you return an inner function. In fact, the enclosing function does not need to return at all. You might instead assign your inner function to a variable in an outer scope, or pass it as an argument to another function where it could be used immediately. Therefore, the closure of the enclosing function probably already exists at the time that enclosing function was called since any inner function has access to it as soon as it is called.

var i;
function foo(x) {
    var tmp = 3;
    i = function (y) {
        console.log(x + y + (++tmp));
    }
}
foo(2);
i(3);

This issue will usually happen when you migrate from react-native < 0.60 to react-native >0.60. If you create a new project in react-native >0.60 you will see the same settings as above mentioned

All this tricks just look (more or less) as local functions, but they don't work like that. In a local function you can use local variables of it's super functions. It's kind of semi-globals. Non of these tricks can do that. The closest is the lambda trick from c++0x, but it's closure is bound in definition time, not the use time.

Firstly, in general:

If these .h files are indeed typical C-style header files (as opposed to being something completely different that just happens to be named with .h extension), then no, there's no reason to "compile" these header files independently. Header files are intended to be included into implementation files, not fed to the compiler as independent translation units.

Since a typical header file usually contains only declarations that can be safely repeated in each translation unit, it is perfectly expected that "compiling" a header file will have no harmful consequences. But at the same time it will not achieve anything useful.

Basically, compiling hello.h as a standalone translation unit equivalent to creating a degenerate dummy.c file consisting only of #include "hello.h" directive, and feeding that dummy.c file to the compiler. It will compile, but it will serve no meaningful purpose.

Secondly, specifically for GCC:

Many compilers will treat files differently depending on the file name extension. GCC has special treatment for files with .h extension when they are supplied to the compiler as command-line arguments. Instead of treating it as a regular translation unit, GCC creates a precompiled header file for that .h file.

You can read about it here: http://gcc.gnu.org/onlinedocs/gcc/Precompiled-Headers.html

So, this is the reason you might see .h files being fed directly to GCC.

$time = '22-09-2008';
echo strtotime($time);

The casting of malloc is unnecessary in C but mandatory in C++.

Casting is unnecessary in C because of:

• void * is automatically and safely promoted to any other pointer type in the case of C.
• It can hide an error if you forgot to include <stdlib.h>. This can cause crashes.
• If pointers and integers are differently sized, then you're hiding a warning by casting and might lose bits of your returned address.
• If the type of the pointer is changed at its declaration, one may also need to change all lines where malloc is called and cast.

On the other hand, casting may increase the portability of your program. i.e, it allows a C program or function to compile as C++.

You can use AWS cloudwatch metrics for s3 to see exact count for each bucket.

Apart from changing to SSH you can also keep using HTTPS, if you don't mind to put your password in clear text. Put this in your ~/.netrc and it won't ask for your username/password (at least on Linux and Mac):

machine github.com
       login <user>
       password <password>

Addition (see VonC's second comment): on Windows the file name is %HOME%\_netrc.

Also read VonC's first comment in case you want to encrypt.

Another addition (see user137717's comment) which you can use if you have Git 1.7.10 or newer.

Cache your GitHub password in Git using a credential helper:

If you're cloning GitHub repositories using HTTPS, you can use a credential helper to tell Git to remember your GitHub username and password every time it talks to GitHub.

This also works on Linux, Mac, and Windows.

Also it'd work to just specify ifelse() twice:

plot(pos,cn, col= ifelse(cn >= 3, "red", ifelse(cn <= 1,"blue", "black")), ylim = c(0, 10))

I have a very simple answer which works:

1. Open PowerShell in administrator mode
2. Run: set-executionpolicy unrestricted
3. Open a regular PowerShell window and run your script.

I found this solution following the link that was given as part of error message: About Execution Policies

You can absolutely inject mocks on MyLauncher in your test. I am sure if you show what mocking framework you are using someone would be quick to provide an answer. With mockito I would look into using @RunWith(MockitoJUnitRunner.class) and using annotations for myLauncher. It would look something like what is below.

@RunWith(MockitoJUnitRunner.class)
public class MyLauncherTest
    @InjectMocks
    private MyLauncher myLauncher = new MyLauncher();

    @Mock
    private MyService myService;

    @Test
    public void someTest() {

    }
}

Guava's function Maps.transformValues is what you are looking for, and it works nicely with lambda expressions:

Maps.transformValues(originalMap, val -> ...)

The other solutions should work, but here is a solution for docker-compose.

To fix that error, you need to pass $DISPLAY and .X11-unix to docker, as well as grant the user who started docker access to xhost.

Within docker-compose.yml file:

version: '2'
services:
    node:
        build: .
        container_name: node
        environment:
            - DISPLAY
        volumes:
            - /tmp/.X11-unix:/tmp/.X11-unix

In terminal or script:

• xhost +si:localuser:$USER
• xhost +local:docker
• export DISPLAY=$DISPLAY
• docker-compose up

On the back of James Lee Baker's reply, I prefer this solution as it removes the reliance on browser support for :first :selected ...

$('#target').children().prop('selected', false);
$($('#target').children()[0]).prop('selected', 'selected');

Use cl scr on the Sql* command line tool to clear all the matter on the screen.

React-Router V4 comes with a NavLink component out of the box

To use, simply set the activeClassName attribute to the class you have appropriately styled, or directly set activeStyle to the styles you want. See the docs for more details.

<NavLink
  to="/hello"
  activeClassName="active"
>Hello</NavLink>

You can use the init files. Check the MySQL official documentation on How to Reset the Root Password (including comments for alternative solutions).

So basically using init files, you can add any SQL queries that you need for fixing your access (such as GRAND, CREATE, FLUSH PRIVILEGES, etc.) into init file (any file).

Here is my example of recovering root account:

echo "CREATE USER 'root'@'localhost' IDENTIFIED BY 'root';" > your_init_file.sql
echo "GRANT ALL PRIVILEGES ON *.* TO 'root'@'localhost' WITH GRANT OPTION;" >> your_init_file.sql 
echo "FLUSH PRIVILEGES;" >> your_init_file.sql

and after you've created your file, you can run:

killall mysqld
mysqld_safe --init-file=$PWD/your_init_file.sql

then to check if this worked, press Ctrl+Z and type: bg to run the process from the foreground into the background, then verify your access by:

mysql -u root -proot
mysql> show grants;
+-------------------------------------------------------------------------------------------------------------+
| Grants for root@localhost                                                                                   |
+-------------------------------------------------------------------------------------------------------------+
| GRANT USAGE ON *.* TO 'root'@'localhost' IDENTIFIED BY PASSWORD '*81F5E21E35407D884A6CD4A731AEBFB6AF209E1B' |

Just in case it may help somebody, you may also try this animator ViewPropertyAnimator as below

myView.animate().x(50f).y(100f);

myView.animate().translateX(pixelInScreen) 

Note: This pixel is not relative to the view. This pixel is the pixel position in the screen.

Or in your SQL query wrap that field with IsNull or Coalesce (SQL Server).

Either way works, I like to put that logic in the query so the report has to do less.

Here ya go - works just any other iterable:

d = {'param' : 'test'}

def f(dictionary):
    for key in dictionary:
        print key

f(d)

Just adding my problem i had:

$this->load->model("planning/plan_model.php");

and the .php shouldnt be there, so it should have been:

$this->load->model("planning/plan_model");

hope this helps someone

I came across this because I was trying to load a JSON file dumped from MongoDB. It was giving me an error

JSONDecodeError: Extra data: line 2 column 1

The MongoDB JSON dump has one object per line, so what worked for me is:

import json
data = [json.loads(line) for line in open('data.json', 'r')]

Python: The Mutable Default Argument

Default arguments get evaluated at the time the function is compiled into a function object. When used by the function, multiple times by that function, they are and remain the same object.

When they are mutable, when mutated (for example, by adding an element to it) they remain mutated on consecutive calls.

They stay mutated because they are the same object each time.

Equivalent code:

Since the list is bound to the function when the function object is compiled and instantiated, this:

def foo(mutable_default_argument=[]): # make a list the default argument
    """function that uses a list"""

is almost exactly equivalent to this:

_a_list = [] # create a list in the globals

def foo(mutable_default_argument=_a_list): # make it the default argument
    """function that uses a list"""

del _a_list # remove globals name binding

Demonstration

Here's a demonstration - you can verify that they are the same object each time they are referenced by

• seeing that the list is created before the function has finished compiling to a function object,
• observing that the id is the same each time the list is referenced,
• observing that the list stays changed when the function that uses it is called a second time,
• observing the order in which the output is printed from the source (which I conveniently numbered for you):

example.py

print('1. Global scope being evaluated')

def create_list():
    '''noisily create a list for usage as a kwarg'''
    l = []
    print('3. list being created and returned, id: ' + str(id(l)))
    return l

print('2. example_function about to be compiled to an object')

def example_function(default_kwarg1=create_list()):
    print('appending "a" in default default_kwarg1')
    default_kwarg1.append("a")
    print('list with id: ' + str(id(default_kwarg1)) + 
          ' - is now: ' + repr(default_kwarg1))

print('4. example_function compiled: ' + repr(example_function))


if __name__ == '__main__':
    print('5. calling example_function twice!:')
    example_function()
    example_function()

and running it with python example.py:

1. Global scope being evaluated
2. example_function about to be compiled to an object
3. list being created and returned, id: 140502758808032
4. example_function compiled: <function example_function at 0x7fc9590905f0>
5. calling example_function twice!:
appending "a" in default default_kwarg1
list with id: 140502758808032 - is now: ['a']
appending "a" in default default_kwarg1
list with id: 140502758808032 - is now: ['a', 'a']

Does this violate the principle of "Least Astonishment"?

This order of execution is frequently confusing to new users of Python. If you understand the Python execution model, then it becomes quite expected.

The usual instruction to new Python users:

But this is why the usual instruction to new users is to create their default arguments like this instead:

def example_function_2(default_kwarg=None):
    if default_kwarg is None:
        default_kwarg = []

This uses the None singleton as a sentinel object to tell the function whether or not we've gotten an argument other than the default. If we get no argument, then we actually want to use a new empty list, [], as the default.

As the tutorial section on control flow says:

If you don’t want the default to be shared between subsequent calls, you can write the function like this instead:

def f(a, L=None):
    if L is None:
        L = []
    L.append(a)
    return L

When constructing a BigInteger with a string, the string must be formatted as a decimal number. You cannot use letters, unless you specify a radix in the second argument, you can specify up to 36 in the radix. 36 will give you alphanumeric characters only [0-9,a-z], so if you use this, you will have no formatting. You can create: new BigInteger("ihavenospaces", 36) Then to convert back, use a .toString(36)

BUT TO KEEP FORMATTING: Use the byte[] method that a couple people mentioned. That will pack the data with formatting into the smallest size, and allow you to keep track of number of bytes easily

That should be perfect for an RSA public key crypto system example program, assuming you keep the number of bytes in the message smaller than the number of bytes of PQ

(I realize this thread is old)

In MSVC++ you can use keyword override

class child : public parent {
public:
  virtual void handle_event(int something) <b>override</b> {
    // new exciting code
  }
};

override works both for native and CLR code in MSVC++.

The use operator is for giving aliases to names of classes, interfaces or other namespaces. Most use statements refer to a namespace or class that you'd like to shorten:

use My\Full\Namespace;

is equivalent to:

use My\Full\Namespace as Namespace;
// Namespace\Foo is now shorthand for My\Full\Namespace\Foo

If the use operator is used with a class or interface name, it has the following uses:

// after this, "new DifferentName();" would instantiate a My\Full\Classname
use My\Full\Classname as DifferentName;

// global class - making "new ArrayObject()" and "new \ArrayObject()" equivalent
use ArrayObject;

The use operator is not to be confused with autoloading. A class is autoloaded (negating the need for include) by registering an autoloader (e.g. with spl_autoload_register). You might want to read PSR-4 to see a suitable autoloader implementation.

there is the class I mentioned in the comment we had with Sean Patrick Floyd : I did it with a peculiar use which needs WeakReference, but you can change it by any object with ease.

Hoping this can help someone someday :)

Straight from the ECMA-262, Fifth Edition ECMAScript Specification:

7.9.1 Rules of Automatic Semicolon Insertion

There are three basic rules of semicolon insertion:

1. When, as the program is parsed from left to right, a token (called the offending token) is encountered that is not allowed by any production of the grammar, then a semicolon is automatically inserted before the offending token if one or more of the following conditions is true:
   • The offending token is separated from the previous token by at least one LineTerminator.
   • The offending token is }.
2. When, as the program is parsed from left to right, the end of the input stream of tokens is encountered and the parser is unable to parse the input token stream as a single complete ECMAScript Program, then a semicolon is automatically inserted at the end of the input stream.
3. When, as the program is parsed from left to right, a token is encountered that is allowed by some production of the grammar, but the production is a restricted production and the token would be the first token for a terminal or nonterminal immediately following the annotation "_{[no LineTerminator here]}" within the restricted production (and therefore such a token is called a restricted token), and the restricted token is separated from the previous token by at least one LineTerminator, then a semicolon is automatically inserted before the restricted token.

However, there is an additional overriding condition on the preceding rules: a semicolon is never inserted automatically if the semicolon would then be parsed as an empty statement or if that semicolon would become one of the two semicolons in the header of a for statement (see 12.6.3).

A well-explained answer is already given by @mkobit, but I will add a big picture of the range key and hash key.

In a simple words range + hash key = composite primary key CoreComponents of Dynamodb

A primary key is consists of a hash key and an optional range key. Hash key is used to select the DynamoDB partition. Partitions are parts of the table data. Range keys are used to sort the items in the partition, if they exist.

So both have a different purpose and together help to do complex query. In the above example hashkey1 can have multiple n-range. Another example of range and hashkey is game, userA(hashkey) can play Ngame(range)

The Music table described in Tables, Items, and Attributes is an example of a table with a composite primary key (Artist and SongTitle). You can access any item in the Music table directly, if you provide the Artist and SongTitle values for that item.

A composite primary key gives you additional flexibility when querying data. For example, if you provide only the value for Artist, DynamoDB retrieves all of the songs by that artist. To retrieve only a subset of songs by a particular artist, you can provide a value for Artist along with a range of values for SongTitle.

For me the most compact and compliant solution to the request is

$ a='1   2\t \t3     4   5   6 7 \t 8\t '; 
$ echo -e "$a" | awk -v n=3 '{while (i<n) {i++; sub($1 FS"*", "")}; print $0}'

And if you have more lines to process as for instance file foo.txt, don't forget to reset i to 0:

$ awk -v n=3 '{i=0; while (i<n) {i++; sub($1 FS"*", "")}; print $0}' foo.txt

Thanks your forum.

Inspired by Martijn Pieters' response.

In case you only need to delete the header from the csv file, you can work more efficiently if you write using the standard Python file I/O library, avoiding writing with the CSV Python library:

with open("tmob_notcleaned.csv", "rb") as infile, open("tmob_cleaned.csv", "wb") as outfile:
   next(infile)  # skip the headers
   outfile.write(infile.read())

sort dictionary 'in_dict' by value in decreasing order

sorted_dict = {r: in_dict[r] for r in sorted(in_dict, key=in_dict.get, reverse=True)}

example above

sorted_d = {r: d[r] for r in sorted(d, key=d.get('key3'), reverse=True)}

I was trying to run this from within the Visual Studio 2017 Package Manager Console. None of the above suggestions worked.

See this link where Microsoft states "The solution is not to use package manager for angular development, but instead use powershell command line. ".

Sorry but all the answers I see here are either hacky or fail if you sneeze a little harder.

If you use a table you can (if you wish) add a space between the divs, set borders, padding...

<table width="100%" cellspacing="0">
    <tr>
        <td style="width:50%;">A</td>
        <td style="width:50%;">B</td>            
    </tr>
</table>

Check a more complete example here: http://jsfiddle.net/qPduw/5/

Solution 1 - largest 'range' with most flexible length

string get_unique_string(int string_length) {
    using(var rng = new RNGCryptoServiceProvider()) {
        var bit_count = (string_length * 6);
        var byte_count = ((bit_count + 7) / 8); // rounded up
        var bytes = new byte[byte_count];
        rng.GetBytes(bytes);
        return Convert.ToBase64String(bytes);
    }
}

This solution has more range than using a GUID because a GUID has a couple of fixed bits that are always the same and therefore not random, for example the 13 character in hex is always "4" - at least in a version 6 GUID.

This solution also lets you generate a string of any length.

Solution 2 - One line of code - good for up to 22 characters

Convert.ToBase64String(Guid.NewGuid().ToByteArray()).Substring(0, 8);

You can't generate strings as long as Solution 1 and the string doesn't have the same range due to fixed bits in GUID's, but in a lot of cases this will do the job.

Solution 3 - Slightly less code

Guid.NewGuid().ToString("n").Substring(0, 8);

Mostly keeping this here for historical purpose. It uses slightly less code, that though comes as the expense of having less range - because it uses hex instead of base64 it takes more characters to represent the same range compared the other solutions.

Which means more chance of collision - testing it with 100,000 iterations of 8 character strings generated one duplicate.

Use rc-if-else module

Use /fonts/ or /font/ before font type name in your CSS stylesheet. I face this error but after that its working fine.

@font-face {

         url('../fonts/Roboto-Regular-webfont.woff') format('woff'),
         url('../fonts/Roboto-Regular-webfont.ttf') format('truetype'),
         url('../fonts/Roboto-Regular-webfont.svg#robotoregular') format('svg');
    font-weight: normal;
    font-style: normal;

}

like this:

final String str = "This is a long sentence";
final String[] arr = str.split(" ", 2);
System.out.println(Arrays.toString(arr));

arr[0] is the first word, arr[1] is the rest

I wanted to answer to the following question which is a little bit different than this:

Best way to print messages on multiple lines

He wanted to show lines from repeated characters too. He wanted this output:

----------------------------------------
# Operator Micro-benchmarks
# Run_mode: short
# Num_repeats: 5
# Num_runs: 1000

----------------------------------------

You can create those lines inside f-strings with a multiplication, like this:

run_mode, num_repeats, num_runs = 'short', 5, 1000

s = f"""
{'-'*40}
# Operator Micro-benchmarks
# Run_mode: {run_mode}
# Num_repeats: {num_repeats}
# Num_runs: {num_runs}

{'-'*40}
"""

print(s)

Just use os.path.join to join your path with the filename and extension. Use sys.argv to access arguments passed to the script when executing it:

#!/usr/bin/env python3
# coding: utf-8

# import netCDF4 as nc
import numpy as np
import numpy.ma as ma
import csv as csv

import os.path
import sys

basedir = '/data/reu_data/soil_moisture/'
suffix = 'nc'


def read_fid(filename):
    fid = nc.MFDataset(filename,'r')
    fid.close()
    return fid

def read_var(file, varname):
    fid = nc.Dataset(file, 'r')
    out = fid.variables[varname][:]
    fid.close()
    return out


if __name__ == '__main__':
    if len(sys.argv) < 2:
        print('Please specify a year')

    else:
        filename = os.path.join(basedir, '.'.join((sys.argv[1], suffix)))
        time = read_var(ncf, 'time')
        lat = read_var(ncf, 'lat')
        lon = read_var(ncf, 'lon')
        soil = read_var(ncf, 'soilw')

Simply run the script like:

   # on windows-based systems
   python script.py year

   # on unix-based systems
   ./script.py year

I wanted to change default java version form 1.6* to 1.7*. I tried the following steps and it worked for me:

• Removed link "java" from under /usr/bin
• Created it again, pointing to the new location:

ln -s /Library/Java/JavaVirtualMachines/jdk1.7.0_51.jdk/Contents/Home/bin/java java

• verified with "java -version"

java version "1.7.0_51"
Java(TM) SE Runtime Environment (build 1.7.0_51-b13)
Java HotSpot(TM) 64-Bit Server VM (build 24.51-b03, mixed mode)

Without regex:

str = str.split("\n").join("<br />");

Say you have a drop down called ddlMonths:

ddlMonths.Items.Insert(0,new ListItem("Select a month","-1");

Use regular expressions. In this case, you can use gsub:

gsub("^.*?_","_","ATGAS_1121")
[1] "_1121"

This regular expression matches the beginning of the string (^), any character (.) repeated zero or more times (*), and underscore (_). The ? makes the match "lazy" so that it only matches are far as the first underscore. That match is replaced with just an underscore. See ?regex for more details and references

The better option is create a new table copy the rows to the destination table, drop the actual table and rename the newly created table . This method is good for small tables,

You're comparing apples to oranges here:

• webHttpBinding is the REST-style binding, where you basically just hit a URL and get back a truckload of XML or JSON from the web service

• basicHttpBinding and wsHttpBinding are two SOAP-based bindings which is quite different from REST. SOAP has the advantage of having WSDL and XSD to describe the service, its methods, and the data being passed around in great detail (REST doesn't have anything like that - yet). On the other hand, you can't just browse to a wsHttpBinding endpoint with your browser and look at XML - you have to use a SOAP client, e.g. the WcfTestClient or your own app.

So your first decision must be: REST vs. SOAP (or you can expose both types of endpoints from your service - that's possible, too).

Then, between basicHttpBinding and wsHttpBinding, there differences are as follows:

• basicHttpBinding is the very basic binding - SOAP 1.1, not much in terms of security, not much else in terms of features - but compatible to just about any SOAP client out there --> great for interoperability, weak on features and security

• wsHttpBinding is the full-blown binding, which supports a ton of WS-* features and standards - it has lots more security features, you can use sessionful connections, you can use reliable messaging, you can use transactional control - just a lot more stuff, but wsHttpBinding is also a lot *heavier" and adds a lot of overhead to your messages as they travel across the network

For an in-depth comparison (including a table and code examples) between the two check out this codeproject article: Differences between BasicHttpBinding and WsHttpBinding

Just put the labels in a div inside the TD and put the height and overflow.. like below.

<table>
<tr>
  <td><div style="height:40px; overflow:hidden">Sample</div></td>
  <td><div style="height:40px; overflow:hidden">Text</div></td>
  <td><div style="height:40px; overflow:hidden">Here</div></td>
</tr>
</table>

// String.class here is the parameter type, that might not be the case with you
Method method = clazz.getMethod("methodName", String.class);
Object o = method.invoke(null, "whatever");

In case the method is private use getDeclaredMethod() instead of getMethod(). And call setAccessible(true) on the method object.

CGRect Can be simply created using an instance of a CGPoint or CGSize, thats given below.

let rect = CGRect(origin: CGPoint(x: 0,y :0), size: CGSize(width: 100, height: 100))  

// Or

let rect = CGRect(origin: .zero, size: CGSize(width: 100, height: 100))

Or if we want to specify each value in CGFloat or Double or Int, we can use this method.

let rect = CGRect(x: 0, y: 0, width: 100, height: 100) // CGFloat, Double, Int

CGPoint Can be created like this.

 let point = CGPoint(x: 0,y :0) // CGFloat, Double, Int

CGSize Can be created like this.

let size = CGSize(width: 100, height: 100) // CGFloat, Double, Int

Also size and point with 0 as the values, it can be done like this.

let size = CGSize.zero // width = 0, height = 0
let point = CGPoint.zero // x = 0, y = 0, equal to CGPointZero
let rect = CGRect.zero // equal to CGRectZero

CGRectZero & CGPointZero replaced with CGRect.zero & CGPoint.zero in Swift 3.0.

Adding to Jacks solution. I need to Deserialize using the JsonProperty and Serialize while ignoring the JsonProperty (or vice versa). ReflectionHelper and Attribute Helper are just helper classes that get a list of properties or attributes for a property. I can include if anyone actually cares. Using the example below you can serialize the viewmodel and get "Amount" even though the JsonProperty is "RecurringPrice".

    /// <summary>
    /// Ignore the Json Property attribute. This is usefule when you want to serialize or deserialize differently and not 
    /// let the JsonProperty control everything.
    /// </summary>
    /// <typeparam name="T"></typeparam>
    public class IgnoreJsonPropertyResolver<T> : DefaultContractResolver
    {
        private Dictionary<string, string> PropertyMappings { get; set; }

        public IgnoreJsonPropertyResolver()
        {
            this.PropertyMappings = new Dictionary<string, string>();
            var properties = ReflectionHelper<T>.GetGetProperties(false)();
            foreach (var propertyInfo in properties)
            {
                var jsonProperty = AttributeHelper.GetAttribute<JsonPropertyAttribute>(propertyInfo);
                if (jsonProperty != null)
                {
                    PropertyMappings.Add(jsonProperty.PropertyName, propertyInfo.Name);
                }
            }
        }

        protected override string ResolvePropertyName(string propertyName)
        {
            string resolvedName = null;
            var resolved = this.PropertyMappings.TryGetValue(propertyName, out resolvedName);
            return (resolved) ? resolvedName : base.ResolvePropertyName(propertyName);
        }
    }

Usage:

        var settings = new JsonSerializerSettings();
        settings.DateFormatString = "YYYY-MM-DD";
        settings.ContractResolver = new IgnoreJsonPropertyResolver<PlanViewModel>();
        var model = new PlanViewModel() {Amount = 100};
        var strModel = JsonConvert.SerializeObject(model,settings);

Model:

public class PlanViewModel
{

    /// <summary>
    ///     The customer is charged an amount over an interval for the subscription.
    /// </summary>
    [JsonProperty(PropertyName = "RecurringPrice")]
    public double Amount { get; set; }

    /// <summary>
    ///     Indicates the number of intervals between each billing. If interval=2, the customer would be billed every two
    ///     months or years depending on the value for interval_unit.
    /// </summary>
    public int Interval { get; set; } = 1;

    /// <summary>
    ///     Number of free trial days that can be granted when a customer is subscribed to this plan.
    /// </summary>
    public int TrialPeriod { get; set; } = 30;

    /// <summary>
    /// This indicates a one-time fee charged upfront while creating a subscription for this plan.
    /// </summary>
    [JsonProperty(PropertyName = "SetupFee")]
    public double SetupAmount { get; set; } = 0;


    /// <summary>
    /// String representing the type id, usually a lookup value, for the record.
    /// </summary>
    [JsonProperty(PropertyName = "TypeId")]
    public string Type { get; set; }

    /// <summary>
    /// Billing Frequency
    /// </summary>
    [JsonProperty(PropertyName = "BillingFrequency")]
    public string Period { get; set; }


    /// <summary>
    /// String representing the type id, usually a lookup value, for the record.
    /// </summary>
    [JsonProperty(PropertyName = "PlanUseType")]
    public string Purpose { get; set; }
}

I have 1 simpler work around...

What you can do is while inserting data/document into your main collection "things" you must insert the attributes in 1 separate collection lets say "things_attributes".

so every time you insert in "things", you do get from "things_attributes" compare values of that document with your new document keys if any new key present append it in that document and again re-insert it.

So things_attributes will have only 1 document of unique keys which you can easily get when ever you require by using findOne()

You have to use reflection to get all the member fields of User class, iterate through them and find their annotations

something like this:

public void getAnnotations(Class clazz){
    for(Field field : clazz.getDeclaredFields()){
        Class type = field.getType();
        String name = field.getName();
        field.getDeclaredAnnotations(); //do something to these
    }
}

If your abstract class contains concrete functionality that has business value, then I will usually test it directly by creating a test double that stubs out the abstract data, or by using a mocking framework to do this for me. Which one I choose depends a lot on whether I need to write test-specific implementations of the abstract methods or not.

The most common scenario in which I need to do this is when I'm using the Template Method pattern, such as when I'm building some sort of extensible framework that will be used by a 3rd party. In this case, the abstract class is what defines the algorithm that I want to test, so it makes more sense to test the abstract base than a specific implementation.

However, I think it's important that these tests should focus on the concrete implementations of real business logic only; you shouldn't unit test implementation details of the abstract class because you'll end up with brittle tests.

I couldn't get this to work and found that I needed to add the "selected" html attribute not only to the correct <option> tag but also to the <select> tag. MDN's docs on the selected attribute of the select tag say:

selected - Boolean attribute indicates that a specific option can be initially selected.

That means the code should look like:

f.select :project_id, options_for_select(@project_select, default_val), html: {selected: true}

What is the difference between iterators and generators? Some examples for when you would use each case would be helpful.

In summary: Iterators are objects that have an __iter__ and a __next__ (next in Python 2) method. Generators provide an easy, built-in way to create instances of Iterators.

A function with yield in it is still a function, that, when called, returns an instance of a generator object:

def a_function():
    "when called, returns generator object"
    yield

A generator expression also returns a generator:

a_generator = (i for i in range(0))

For a more in-depth exposition and examples, keep reading.

A Generator is an Iterator

Specifically, generator is a subtype of iterator.

>>> import collections, types
>>> issubclass(types.GeneratorType, collections.Iterator)
True

We can create a generator several ways. A very common and simple way to do so is with a function.

Specifically, a function with yield in it is a function, that, when called, returns a generator:

>>> def a_function():
        "just a function definition with yield in it"
        yield
>>> type(a_function)
<class 'function'>
>>> a_generator = a_function()  # when called
>>> type(a_generator)           # returns a generator
<class 'generator'>

And a generator, again, is an Iterator:

>>> isinstance(a_generator, collections.Iterator)
True

An Iterator is an Iterable

An Iterator is an Iterable,

>>> issubclass(collections.Iterator, collections.Iterable)
True

which requires an __iter__ method that returns an Iterator:

>>> collections.Iterable()
Traceback (most recent call last):
  File "<pyshell#79>", line 1, in <module>
    collections.Iterable()
TypeError: Can't instantiate abstract class Iterable with abstract methods __iter__

Some examples of iterables are the built-in tuples, lists, dictionaries, sets, frozen sets, strings, byte strings, byte arrays, ranges and memoryviews:

>>> all(isinstance(element, collections.Iterable) for element in (
        (), [], {}, set(), frozenset(), '', b'', bytearray(), range(0), memoryview(b'')))
True

Iterators require a next or __next__ method

In Python 2:

>>> collections.Iterator()
Traceback (most recent call last):
  File "<pyshell#80>", line 1, in <module>
    collections.Iterator()
TypeError: Can't instantiate abstract class Iterator with abstract methods next

And in Python 3:

>>> collections.Iterator()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: Can't instantiate abstract class Iterator with abstract methods __next__

We can get the iterators from the built-in objects (or custom objects) with the iter function:

>>> all(isinstance(iter(element), collections.Iterator) for element in (
        (), [], {}, set(), frozenset(), '', b'', bytearray(), range(0), memoryview(b'')))
True

The __iter__ method is called when you attempt to use an object with a for-loop. Then the __next__ method is called on the iterator object to get each item out for the loop. The iterator raises StopIteration when you have exhausted it, and it cannot be reused at that point.

From the documentation

From the Generator Types section of the Iterator Types section of the Built-in Types documentation:

Python’s generators provide a convenient way to implement the iterator protocol. If a container object’s __iter__() method is implemented as a generator, it will automatically return an iterator object (technically, a generator object) supplying the __iter__() and next() [__next__() in Python 3] methods. More information about generators can be found in the documentation for the yield expression.

(Emphasis added.)

So from this we learn that Generators are a (convenient) type of Iterator.

Example Iterator Objects

You might create object that implements the Iterator protocol by creating or extending your own object.

class Yes(collections.Iterator):

    def __init__(self, stop):
        self.x = 0
        self.stop = stop

    def __iter__(self):
        return self

    def next(self):
        if self.x < self.stop:
            self.x += 1
            return 'yes'
        else:
            # Iterators must raise when done, else considered broken
            raise StopIteration

    __next__ = next # Python 3 compatibility

But it's easier to simply use a Generator to do this:

def yes(stop):
    for _ in range(stop):
        yield 'yes'

Or perhaps simpler, a Generator Expression (works similarly to list comprehensions):

yes_expr = ('yes' for _ in range(stop))

They can all be used in the same way:

>>> stop = 4             
>>> for i, y1, y2, y3 in zip(range(stop), Yes(stop), yes(stop), 
                             ('yes' for _ in range(stop))):
...     print('{0}: {1} == {2} == {3}'.format(i, y1, y2, y3))
...     
0: yes == yes == yes
1: yes == yes == yes
2: yes == yes == yes
3: yes == yes == yes

Conclusion

You can use the Iterator protocol directly when you need to extend a Python object as an object that can be iterated over.

However, in the vast majority of cases, you are best suited to use yield to define a function that returns a Generator Iterator or consider Generator Expressions.

Finally, note that generators provide even more functionality as coroutines. I explain Generators, along with the yield statement, in depth on my answer to "What does the “yield” keyword do?".

I'm using, Angular CLI: 8.1.2 Node: 12.14.1 OS: win32 x64

Strangely, this helped me

npm cache clean --force
npm uninstall @angular/cli
npm install @angular/[email protected]

This code work for me:

    BufferedImage image = null;
    try {
        URL file = getClass().getResource("water.bmp");
        image = ImageIO.read(file);
    } catch (IOException ioex) {

    }
    ImageIcon icon = new ImageIcon(image);
    JButton quitButton = new JButton(icon);

Xml example: will produce a circle of 5dp

 <com.example.CircleView

        android:layout_height="10dp"/>

Up until now (December 2017), this is the only solution I found which works both inside and outside the IDE.

Use PathMatchingResourcePatternResolver

Note: it works also in spring-boot

In this example I'm reading some files located in src/main/resources/my_folder:

try {
    // Get all the files under this inner resource folder: my_folder
    String scannedPackage = "my_folder/*";
    PathMatchingResourcePatternResolver scanner = new PathMatchingResourcePatternResolver();
    Resource[] resources = scanner.getResources(scannedPackage);

    if (resources == null || resources.length == 0)
        log.warn("Warning: could not find any resources in this scanned package: " + scannedPackage);
    else {
        for (Resource resource : resources) {
            log.info(resource.getFilename());
            // Read the file content (I used BufferedReader, but there are other solutions for that):
            BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(resource.getInputStream()));
            String line = null;
            while ((line = bufferedReader.readLine()) != null) {
                // ...
                // ...                      
            }
            bufferedReader.close();
        }
    }
} catch (Exception e) {
    throw new Exception("Failed to read the resources folder: " + e.getMessage(), e);

One step (IMHO) better

$result .= $personCount . ' people';

Another way:

var main = App.Current.MainWindow as MainWindow;

TL;DR: Specify key file in group variable file, since 'tag_Name_server1' is a group.

Note: I'm assuming you're using the EC2 external inventory script. If you're using some other dynamic inventory approach, you might need to tweak this solution.

This is an issue I've been struggling with, on and off, for months, and I've finally found a solution, thanks to Brian Coca's suggestion here. The trick is to use Ansible's group variable mechanisms to automatically pass along the correct SSH key file for the machine you're working with.

The EC2 inventory script automatically sets up various groups that you can use to refer to hosts. You're using this in your playbook: in the first play, you're telling Ansible to apply 'role1' to the entire 'tag_Name_server1' group. We want to direct Ansible to use a specific SSH key for any host in the 'tag_Name_server1' group, which is where group variable files come in.

Assuming that your playbook is located in the 'my-playbooks' directory, create files for each group under the 'group_vars' directory:

my-playbooks
|-- test.yml
+-- group_vars
     |-- tag_Name_server1.yml
     +-- tag_Name_server2.yml

Now, any time you refer to these groups in a playbook, Ansible will check the appropriate files, and load any variables you've defined there.

Within each group var file, we can specify the key file to use for connecting to hosts in the group:

# tag_Name_server1.yml
# --------------------
# 
# Variables for EC2 instances named "server1"
---
ansible_ssh_private_key_file: /path/to/ssh/key/server1.pem

Now, when you run your playbook, it should automatically pick up the right keys!

Using environment vars for portability

I often run playbooks on many different servers (local, remote build server, etc.), so I like to parameterize things. Rather than using a fixed path, I have an environment variable called SSH_KEYDIR that points to the directory where the SSH keys are stored.

In this case, my group vars files look like this, instead:

# tag_Name_server1.yml
# --------------------
# 
# Variables for EC2 instances named "server1"
---
ansible_ssh_private_key_file: "{{ lookup('env','SSH_KEYDIR') }}/server1.pem"

Further Improvements

There's probably a bunch of neat ways this could be improved. For one thing, you still need to manually specify which key to use for each group. Since the EC2 inventory script includes details about the keypair used for each server, there's probably a way to get the key name directly from the script itself. In that case, you could supply the directory the keys are located in (as above), and have it choose the correct keys based on the inventory data.

if ( 100 < 500 ) {
   //any action
}
else if ( 100 > 500 ){
   //any another action
}

Easy, use space

As far as I know there is no mechanism for doing this in JUnit, however you could try subclassing Suite and overriding the run() method with a version that does provide hooks.

EDIT: For a better description, see x86 Disassembly/Functions and Stack Frames in a WikiBook about x86 assembly. I try to add some info you might be interested in using Visual Studio.

Storing the caller EBP as the first local variable is called a standard stack frame, and this may be used for nearly all calling conventions on Windows. Differences exist whether the caller or callee deallocates the passed parameters, and which parameters are passed in registers, but these are orthogonal to the standard stack frame problem.

Speaking about Windows programs, you might probably use Visual Studio to compile your C++ code. Be aware that Microsoft uses an optimization called Frame Pointer Omission, that makes it nearly impossible to do walk the stack without using the dbghlp library and the PDB file for the executable.

This Frame Pointer Omission means that the compiler does not store the old EBP on a standard place and uses the EBP register for something else, therefore you have hard time finding the caller EIP without knowing how much space the local variables need for a given function. Of course Microsoft provides an API that allows you to do stack-walks even in this case, but looking up the symbol table database in PDB files takes too long for some use cases.

To avoid FPO in your compilation units, you need to avoid using /O2 or need to explicitly add /Oy- to the C++ compilation flags in your projects. You probably link against the C or C++ runtime, which uses FPO in the Release configuration, so you will have hard time to do stack walks without the dbghlp.dll.

Parse a time with timezone, Z in pattern is for time zone

String aTime = "2017-10-25T11:39:00+09:00";
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ssZ", Locale.getDefault());
try {
    Calendar cal = Calendar.getInstance();
    cal.setTime(sdf.parse(aTime));
    Log.i(TAG, "time = " + cal.getTimeInMillis()); 
} catch (ParseException e) {
    e.printStackTrace();
}

Output: it will return the UTC time

1508899140000

If we don't set the time zone in pattern like yyyy-MM-dd'T'HH:mm:ss. SimpleDateFormat will use the time zone which have set in Setting

Because '' is not a valid Javascript/JSON object. An empty object would be '{}'

For Apache Cassandra 2.0 you need to take into account the following TCP ports: (See EC2 security group configuration and Apache Cassandra FAQ)

Cassandra

• 7199 JMX monitoring port
• 1024 - 65355 Random port required by JMX. Starting with Java 7u4 a specific port can be specified using the com.sun.management.jmxremote.rmi.port property.
• 7000 Inter-node cluster
• 7001 SSL inter-node cluster
• 9042 CQL Native Transport Port
• 9160 Thrift

DataStax OpsCenter

• 61620 opscenterd daemon
• 61621 Agent
• 8888 Website

Architecture

A possible architecture with Cassandra + OpsCenter on EC2 could look like this:

CODE:

import codecs

path="D:\\Users\\html\\abc.html" 
file=codecs.open(path,"rb")
file1=file.read()
file1=str(file1)

As many excellent answers noted, there are a lot of limits that depend on your version of C++ compiler, operating system and computer characteristics. However, I suggest the following script on Python that checks the limit on your machine.

It uses binary search and on each iteration checks if the middle size is possible by creating a code that attempts to create an array of the size. The script tries to compile it (sorry, this part works only on Linux) and adjust binary search depending on the success. Check it out:

import os

cpp_source = 'int a[{}]; int main() {{ return 0; }}'

def check_if_array_size_compiles(size):
        #  Write to file 1.cpp
        f = open(name='1.cpp', mode='w')
        f.write(cpp_source.format(m))
        f.close()
        #  Attempt to compile
        os.system('g++ 1.cpp 2> errors')
        #  Read the errors files
        errors = open('errors', 'r').read()
        #  Return if there is no errors
        return len(errors) == 0

#  Make a binary search. Try to create array with size m and
#  adjust the r and l border depending on wheather we succeeded
#  or not
l = 0
r = 10 ** 50
while r - l > 1:
        m = (r + l) // 2
        if check_if_array_size_compiles(m):
                l = m
        else:
                r = m

answer = l + check_if_array_size_compiles(r)
print '{} is the maximum avaliable length'.format(answer)

You can save it to your machine and launch it, and it will print the maximum size you can create. For my machine it is 2305843009213693951.

::-webkit-scrollbar {
  display: none;
}

It will not work in Firefox, as the Firefox abandoned the support for hidden scrollbars with functionality (you can use overflow: -moz-scrollbars-none; in old versions).

you can do like this.....the below example shows text box(user control) value changed

   // Declare a delegate 
public delegate void ValueChangedEventHandler(object sender, ValueChangedEventArgs e);
public partial class SampleUserControl : TextBox 
{    
    public SampleUserControl() 
    { 
        InitializeComponent(); 
    }

    // Declare an event 
    public event ValueChangedEventHandler ValueChanged;

    protected virtual void OnValueChanged(ValueChangedEventArgs e) 
    { 
        if (ValueChanged != null) 
            ValueChanged(this,e); 
    }    
    private void SampleUserControl_TextChanged(object sender, EventArgs e) 
    { 
        TextBox tb  = (TextBox)sender; 
        int value; 
        if (!int.TryParse(tb.Text, out value)) 
            value = 0; 
        // Raise the event 
       OnValueChanged( new ValueChangedEventArgs(value)); 
    }    
}

I really like the philosophy of the ezSQL database library, which wraps the native SQL methods in an easier-to-use interface.

Fetching a single value from the database is trivial:

  $id = $db->get_var("SELECT id FROM games WHERE ...");

It also makes it easy to fetch a single row, column, or set of rows.

I don't know why my web service has the same structure with you but it doesn't need Class for parameter, just is array.

Since I can not comment because of not having enough reward points I have to answer to correct answer given by @Burhan Khalid.
In very layman language Enter key press is combination of carriage return and line feed.
Carriage return points the cursor to the beginning of the line horizontly and Line feed shifts the cursor to the next line vertically.Combination of both gives you new line(\n) effect.
Reference - https://en.wikipedia.org/wiki/Carriage_return#Computers

The difference is that raw_input() does not exist in Python 3.x, while input() does. Actually, the old raw_input() has been renamed to input(), and the old input() is gone, but can easily be simulated by using eval(input()). (Remember that eval() is evil. Try to use safer ways of parsing your input if possible.)

Try manually start the service from Windows services, Start -> cmd.exe -> services.msc. Also try to configure the MySQL server to run on another port and try starting it again. Change the my.ini file to change the port number.

The code from Alex works great. Just note that when you use request.getParameter you must use a request dispatcher

//Pass results back to the client
RequestDispatcher dispatcher =   getServletContext().getRequestDispatcher("TestPages/ServiceServlet.jsp");
dispatcher.forward(request, response);

You should use the new available m2e plugin for Maven integration in Eclipse. With help of that plugin, you should create a new project and move your sources into that project. These are the steps:

• Check if m2e (or the former m2eclipse) are installed in your Eclipse distribution. If not, install it.
• Open the "New Project Wizard": File > New > Project...
• Open Maven and select Maven Project and click Next.
• Select Create a simple project (to skip the archetype selection).
• Add the necessary information: Group Id, Artifact Id, Packaging == jar, and a Name.
• Finish the Wizard.
• Your new Maven project is now generated, and you are able to move your sources and test packages to the relevant location in your workspace.
• After that, you can build your project (inside Eclipse) by selecting your project, then calling from the context menu Run as > Maven install.

You do not need the latex2exp package to do what you wanted to do. The following code would do the trick.

ggplot(smr, aes(Fuel.Rate, Eng.Speed.Ave., color=Eng.Speed.Max.)) + 
  geom_point() + 
  labs(title=expression("Fuel Efficiency"~(alpha*Omega)), 
color=expression(alpha*Omega), x=expression(Delta~price))

Also, some comments (unanswered as of this point) asked about putting an asterisk (*) after a Greek letter. expression(alpha~"*") works, so I suggest giving it a try.

More comments asked about getting ? Price and I find the most straightforward way to achieve that is expression(Delta~price)). If you need to add something before the Greek letter, you can also do this: expression(Indicative~Delta~price) which gets you:

Looking at your code, I'm not sure why you're getting that error, but I had this same error but with EditText fields.

Changing android:inputType="text" (or any of the other inputType text variations) to android:inputType="textNoSuggestions" (or android:inputType="textEmailAddress|textNoSuggestions", for example) fixed it for me.

You can also set this in Code with something like

mInputField.setInputType(InputType.TYPE_CLASS_TEXT | InputType.TYPE_TEXT_FLAG_NO_SUGGESTIONS);

Looks like Android assumes by default that EditText fields will have suggestions. When they don't, it errors. Not 100% confident in that explanation, but the above mentioned changes fixed it for me.

There is a CSS3 working draft that will (hopefully soon) allow you to write just:

p { text-indent: 200px hanging; }

Keep an eye on: https://developer.mozilla.org/en-US/docs/Web/CSS/text-indent

1. Download the "google-service.json" file from Firebase
2. Go to this address in windows explorer "C:\Users\Your-Username\AndroidStudioProjects" You will see a list of your Android Studio projects
3. Open a desired project, navigate to "app" folder and paste the .json file
4. Go to Android Studio and click on "Sync with file system", located in dropdown menu (File>Sync with file system)
5. Now sync with Gradle and everything should be fine

In HTML in <input> field write: (keypress)="onlyNumberKey($event)"

and in ts file write:

onlyNumberKey(event) {
    return (event.charCode == 8 || event.charCode == 0) ? null : event.charCode >= 48 && event.charCode <= 57;
}

You could just do this:

var rnd = new Random();
return (MyEnum) rnd.Next(Enum.GetNames(typeof(MyEnum)).Length);

No need to store arrays

I ran into this problem since I've been doing React Native since the early days. Google has deprecated the commandline tools and insists on Android studio. The solution for me was to remove the commandline tools

rm -rf /usr/local/Cellar/android-sdk

rm /usr/local/bin/android

open up AS install sdk v6 as instructed https://facebook.github.io/react-native/docs/getting-started.html#1-install-android-studio

make a new AVD and it'll launch without error

DAO is an act like as "Persistence Manager " in 3 tier architecture as well as DAO also design pattern as you can consult "Gang of Four" book. Your application service layer just need to call the method of DAO class without knowing hidden & internal details of DAO's method.

First, I would try and refactor these tables to get away from using phone numbers as natural keys. I am not a fan of natural keys and this is a great example why. Natural keys, especially things like phone numbers, can change and frequently so. Updating your database when that change happens will be a HUGE, error-prone headache. *

Method 1 as you describe it is your best bet though. It looks a bit terse due to the naming scheme and the short aliases but... aliasing is your friend when it comes to joining the same table multiple times or using subqueries etc.

I would just clean things up a bit:

SELECT t.PhoneNumber1, t.PhoneNumber2, 
   t1.SomeOtherFieldForPhone1, t2.someOtherFieldForPhone2
FROM Table1 t
JOIN Table2 t1 ON t1.PhoneNumber = t.PhoneNumber1
JOIN Table2 t2 ON t2.PhoneNumber = t.PhoneNumber2

What i did:

• No need to specify INNER - it's implied by the fact that you don't specify LEFT or RIGHT
• Don't n-suffix your primary lookup table
• N-Suffix the table aliases that you will use multiple times to make it obvious

*One way DBAs avoid the headaches of updating natural keys is to not specify primary keys and foreign key constraints which further compounds the issues with poor db design. I've actually seen this more often than not.

In my case, I had a nested list as the series that I wanted to use as an input.

First check: If

df['nestedList'][0]

outputs a list like [1,2,3], you have a nested list.

Then check if you still get the error when changing to input df['nestedList'][0].

Then your next step is probably to concatenate all nested lists into one unnested list, using

[item for sublist in df['nestedList'] for item in sublist]

This flattening of the nested list is borrowed from How to make a flat list out of list of lists?.

Three options here.

1. Standard JavaScript answer: Use a framework! Most Ajax frameworks will have abstracted you an easy way to make an XMLHTTPRequest POST.

2. Make the XMLHTTPRequest request yourself, passing post into the open method instead of get. (More information in Using POST method in XMLHTTPRequest (Ajax).)

3. Via JavaScript, dynamically create a form, add an action, add your inputs, and submit that.

My variation of Bufke's answer. Avoids a bit of branching with the array and ignores empty cells / columns.

Now fixed for non-string cell values.

ws = your current worksheet
dims = {}
for row in ws.rows:
    for cell in row:
        if cell.value:
            dims[cell.column] = max((dims.get(cell.column, 0), len(str(cell.value))))    
for col, value in dims.items():
    ws.column_dimensions[col].width = value

As of openpyxl version 3.0.3 you need to use

 dims[cell.column_letter] = max((dims.get(cell.column_letter, 0), len(str(cell.value))))

as the openpyxl library will raise a TypeError if you pass column_dimensions a number instead of a column letter, everything else can stay the same.

There are a number of "is methods" on strings. islower() and isupper() should meet your needs:

>>> 'hello'.islower()
True

>>> [m for m in dir(str) if m.startswith('is')]
['isalnum', 'isalpha', 'isdigit', 'islower', 'isspace', 'istitle', 'isupper']

Here's an example of how to use those methods to classify a list of strings:

>>> words = ['The', 'quick', 'BROWN', 'Fox', 'jumped', 'OVER', 'the', 'Lazy', 'DOG']
>>> [word for word in words if word.islower()]
['quick', 'jumped', 'the']
>>> [word for word in words if word.isupper()]
['BROWN', 'OVER', 'DOG']
>>> [word for word in words if not word.islower() and not word.isupper()]
['The', 'Fox', 'Lazy']

This is the very basic

awk '/pattern/{ print $0 }' file

ask awk to search for pattern using //, then print out the line, which by default is called a record, denoted by $0. At least read up the documentation.

If you only want to get print out the matched word.

awk '{for(i=1;i<=NF;i++){ if($i=="yyy"){print $i} } }' file

My approach is very close to Garret Wilson's (thanks, I voted you up ;)

In addition it provides downward compatibility with Android < 3.

I just recognized that my solution is even closer to the one by Kevin Remo. It's just a wee bit cleaner (as it does not rely on the "expection" antipattern).

public class MyPreferenceActivity extends PreferenceActivity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        if (Build.VERSION.SDK_INT < Build.VERSION_CODES.HONEYCOMB) {
            onCreatePreferenceActivity();
        } else {
            onCreatePreferenceFragment();
        }
    }

    /**
     * Wraps legacy {@link #onCreate(Bundle)} code for Android < 3 (i.e. API lvl
     * < 11).
     */
    @SuppressWarnings("deprecation")
    private void onCreatePreferenceActivity() {
        addPreferencesFromResource(R.xml.preferences);
    }

    /**
     * Wraps {@link #onCreate(Bundle)} code for Android >= 3 (i.e. API lvl >=
     * 11).
     */
    @TargetApi(Build.VERSION_CODES.HONEYCOMB)
    private void onCreatePreferenceFragment() {
        getFragmentManager().beginTransaction()
                .replace(android.R.id.content, new MyPreferenceFragment ())
                .commit();
    }
}

For a "real" (but more complex) example see NusicPreferencesActivity and NusicPreferencesFragment.

Yes, right click the project. Click Run as then Run Configurations. You can change the parameters passed to the JVM in the Arguments tab in the VM Arguments box.

That configuration can then be used as the default when running the project.

I had the same problem on windows 10, IIS/10.0 was using port 80

To solve that:

• find service "W3SVC"
• disable it, or set it to "manual"

French name is: "Service de publication World Wide Web"

English name is: "World Wide Web Publishing Service"

german name is: "WWW-Publishingdienst" – thanks @fiffy

Expanding the shortand properties

According to W3C CSS2.1 specification (“Omitted values are set to their initial values”), the following properties are equivalent:

border: hidden;    border-style: hidden;
                   border-width: medium;
                   border-color: <the same as 'color' property>

border: none;      border-style: none;
                   border-width: medium;
                   border-color: <the same as 'color' property>

border: 0;         border-style: none;
                   border-width: 0;
                   border-color: <the same as 'color' property>

If these rules are the most specific ones applied to the borders of an element, then the borders won't be shown, either because of zero-width, or because of hidden/none style. So, at the first look, these three rules look equivalent. However, they behave in different ways when combined with other rules.

Borders in a table context in collapsing border model

When a table is rendered using border-collapse: collapse, then each rendered border is shared between multiple elements (inner borders are shared among as neighbor cells; outer borders are shared between cells and the table itself; but also rows, row groups, columns and column groups share borders). The specification defines some rules for border conflict resolution:

1. Borders with the border-style of hidden take precedence over all other conflicting borders. […]

2. Borders with a style of none have the lowest priority. […]

3. If none of the styles are hidden and at least one of them is not none, then narrow borders are discarded in favor of wider ones. […]

4. If border styles differ only in color, […]

So, in a table context, border: hidden (or border-style: hidden) will have the highest priority and will make the shared border hidden, no matter what.

On the other end of the priorities, border: none (or border-style: none) have the lowest priority, followed by the zero-width border (because it is the narrowest border). This means that a computed value of border-style: none and a computed value of border-width: 0 are essentially the same.

Cascading rules and inheritance

Since none and 0 affect different properties (border-style and border-width), they will behave differently when a more specific rule defines just the style or just the width. See Chris answer for an example.

Live demo!

Want to see all these cases in one single page? Open the live demo!

This function will tell you the x,y position of the element relative to the page. Basically you have to loop up through all the element's parents and add their offsets together.

function getPos(el) {
    // yay readability
    for (var lx=0, ly=0;
         el != null;
         lx += el.offsetLeft, ly += el.offsetTop, el = el.offsetParent);
    return {x: lx,y: ly};
}

However, if you just wanted the x,y position of the element relative to its container, then all you need is:

var x = el.offsetLeft, y = el.offsetTop;

To put an element directly below this one, you'll also need to know its height. This is stored in the offsetHeight/offsetWidth property.

var yPositionOfNewElement = el.offsetTop + el.offsetHeight + someMargin;

Using the length property you can do this.

jQuery.fn.exists = function(){return ($(this).length < 0);}
if ($(selector).exists()) { 
   //do somthing
}

Based on this Connect feedback I fixed it by closing all opened documents and restarting Visual Studio. I use Visual Studio 2015.

Just check the length of files property, which is a FileList object contained on the input element

if( document.getElementById("videoUploadFile").files.length == 0 ){
    console.log("no files selected");
}

I assume bash is running on a vt100-compatible terminal in which the user did not explicitly turn off the support for formatting.

First, turn on support for special characters in echo, using -e option. Later, use ansi escape sequence ESC[1m, like:

echo -e "\033[1mSome Text"

More on ansi escape sequences for example here: ascii-table.com/ansi-escape-sequences-vt-100.php

You shouldn't use both ngRoute and UI-router. Here's a sample code for UI-router:

repoApp.config(function($stateProvider, $urlRouterProvider) {_x000D_
  _x000D_
  $stateProvider_x000D_
    .state('state1', {_x000D_
      url: "/state1",_x000D_
      templateUrl: "partials/state1.html",_x000D_
      controller: 'YourCtrl'_x000D_
    })_x000D_
    _x000D_
    .state('state2', {_x000D_
      url: "/state2",_x000D_
      templateUrl: "partials/state2.html",_x000D_
      controller: 'YourOtherCtrl'_x000D_
    });_x000D_
    $urlRouterProvider.otherwise("/state1");_x000D_
});_x000D_
//etc.

You can find a great answer on the difference between these two in this thread: What is the difference between angular-route and angular-ui-router?

You can also consult UI-Router's docs here: https://github.com/angular-ui/ui-router

I like ggplot too.

Here's one example:

df1 = data.frame(
date_id = c('2017-08-01', '2017-08-02', '2017-08-03', '2017-08-04'),          
nation = c('China', 'USA', 'China', 'USA'), 
value = c(4.0, 5.0, 6.0, 5.5))

ggplot(df1, aes(date_id, value, group=nation, colour=nation))+geom_line()+xlab(label='dates')+ylab(label='value')

echo $_product->getImageUrl();

This method of the Product class should do the trick for you.

android:inputType="text"

should bring the same effect. After hiting next to bring the focus to the next element.

android:nextFocusDown="@+id/.."

use this in addition if you dont want the next view to get the focus

this may help

string parentOfStartupPath = Path.GetFullPath(Path.Combine(Application.StartupPath, @"../../")) + "Orders.xml";
if (File.Exists(parentOfStartupPath))
{
    // file found
}

The difference between GET and POST should not be viewed in terms of security, but rather in their intentions towards the server. GET should never change data on the server - at least other than in logs - but POST can create new resources.

Nice proxies won't cache POST data, but they may cache GET data from the URL, so you could say that POST is supposed to be more secure. But POST data would still be available to proxies that don't play nicely.

As mentioned in many of the answers, the only sure bet is via SSL.

But DO make sure that GET methods do not commit any changes, such as deleting database rows, etc.

Try shelljs to call c/c++ program or shared libraries by using node program from linux/unix . node-cmd an option in windows. Both packages basically enable us to call c/c++ program similar to the way we call from terminal/command line.

Eg in ubuntu:

const shell = require('shelljs');

shell.exec("command or script name");

In windows:

const cmd = require('node-cmd');
cmd.run('command here');

Note: shelljs and node-cmd are for running os commands, not specific to c/c++.

I believe using --no-index is what you're looking for:

git diff [<options>] --no-index [--] <path> <path>

as mentioned in the git manual:

This form is to compare the given two paths on the filesystem. You can omit the --no-index option when running the command in a working tree controlled by Git and at least one of the paths points outside the working tree, or when running the command outside a working tree controlled by Git.

In my case, while using the --date option, my git process crashed. May be I did something terrible. And as a result some index.lock file appeared. So I manually deleted the .lock files from .git folder and executed, for all modified files to be commited in passed dates and it worked this time. Thanx for all the answers here.

git commit --date="`date --date='2 day ago'`" -am "update"

Here is a simple snippet that read's in a json text file from a dictionary. Note that your json file must follow the json standard, so it has to have " double quotes rather then ' single quotes.

Your JSON dump.txt File:

{"test":"1", "test2":123}

Python Script:

import json
with open('/your/path/to/a/dict/dump.txt') as handle:
    dictdump = json.loads(handle.read())

According to Google documentation they said that this is the best way to do it. First create this function to find out how many markers there are/

   function setMapOnAll(map1) {
    for (var i = 0; i < markers.length; i++) {
      markers[i].setMap(map1);
    }
  }

Next create another function to take away all these markers

 function clearMarker(){
setMapOnAll(null);
}

Then create this final function to erase all the markers when ever this function is called upon.

 function delateMarkers(){
clearMarker()
markers = []
//console.log(markers) This is just if you want to

}

Hope that helped good luck

DROP USER 'user'@'localhost';

The above command will drop the user from the database, however, it is Important to know if the same user is already using the database, that session will not end until the user closes that session. It is important to note that dropped user will STILL access the database and perform any operations. DROPPING THE USER DOES NOT DROP THE CURRENT USER SESSION

Check The port 1521 in your server. May be its blocked by firewall. Or disable firewall and try.

You have to declare your functions before main()

(or declare the function prototypes before main())

As it is, the compiler sees my_print (my_string); in main() as a function declaration.

Move your functions above main() in the file, or put:

void my_print (char *);
void my_print2 (char *);

Above main() in the file.

You have to write your own transformation. Only decimal, hex and octal numbers are supported with format specifiers.

Currently, there is no cross browser, script-free way of styling a native date picker.

As for what's going on inside WHATWG/W3C... If this functionality does emerge, it will likely be under the CSS-UI standard or some Shadow DOM-related standard. The CSS4-UI wiki page lists a few appearance-related things that were dropped from CSS3-UI, but to be honest, there doesn't seem to be a great deal of interest in the CSS-UI module.

I think your best bet for cross browser development right now, is to implement pretty controls with JavaScript based interface, and then disable the HTML5 native UI and replace it. I think in the future, maybe there will be better native control styling, but perhaps more likely will be the ability to swap out a native control for your own Shadow DOM "widget".

It is annoying that this isn't available, and petitioning for standard support is always worthwhile. Though it does seem like jQuery UI's lead has tried and was unsuccessful.

While this is all very discouraging, it's also worth considering the advantages of the HTML5 date picker, and also why custom styles are difficult and perhaps should be avoided. On some platforms, the datepicker looks extremely different and I personally can't think of any generic way of styling the native datepicker.

Hopefully this is self explanatory enough. Use the comments in the code to help understand what is happening. Pass a single cell to this function. The value of that cell will be the base file name. If the cell contains "AwesomeData" then we will try and create a file in the current users desktop called AwesomeData.pdf. If that already exists then try AwesomeData2.pdf and so on. In your code you could just replace the lines filename = Application..... with filename = GetFileName(Range("A1"))

Function GetFileName(rngNamedCell As Range) As String
    Dim strSaveDirectory As String: strSaveDirectory = ""
    Dim strFileName As String: strFileName = ""
    Dim strTestPath As String: strTestPath = ""
    Dim strFileBaseName As String: strFileBaseName = ""
    Dim strFilePath As String: strFilePath = ""
    Dim intFileCounterIndex As Integer: intFileCounterIndex = 1

    ' Get the users desktop directory.
    strSaveDirectory = Environ("USERPROFILE") & "\Desktop\"
    Debug.Print "Saving to: " & strSaveDirectory

    ' Base file name
    strFileBaseName = Trim(rngNamedCell.Value)
    Debug.Print "File Name will contain: " & strFileBaseName

    ' Loop until we find a free file number
    Do
        If intFileCounterIndex > 1 Then
            ' Build test path base on current counter exists.
            strTestPath = strSaveDirectory & strFileBaseName & Trim(Str(intFileCounterIndex)) & ".pdf"
        Else
            ' Build test path base just on base name to see if it exists.
            strTestPath = strSaveDirectory & strFileBaseName & ".pdf"
        End If

        If (Dir(strTestPath) = "") Then
            ' This file path does not currently exist. Use that.
            strFileName = strTestPath
        Else
            ' Increase the counter as we have not found a free file yet.
            intFileCounterIndex = intFileCounterIndex + 1
        End If

    Loop Until strFileName <> ""

    ' Found useable filename
    Debug.Print "Free file name: " & strFileName
    GetFileName = strFileName

End Function

The debug lines will help you figure out what is happening if you need to step through the code. Remove them as you see fit. I went a little crazy with the variables but it was to make this as clear as possible.

In Action

My cell O1 contained the string "FileName" without the quotes. Used this sub to call my function and it saved a file.

Sub Testing()
    Dim filename As String: filename = GetFileName(Range("o1"))

    ActiveWorkbook.Worksheets("Sheet1").Range("A1:N24").ExportAsFixedFormat Type:=xlTypePDF, _
                                              filename:=filename, _
                                              Quality:=xlQualityStandard, _
                                              IncludeDocProperties:=True, _

Where is your code located in reference to everything else? Perhaps you need to make a module if you have not already and move your existing code into there.

You can also achieve this effect using XML, as seen here, which removes the limitation of the answers provided which all seem to include recursion in some fashion. The particular use I've made here allows for up to a 32-character delimiter, but that could be increased however large it needs to be.

create FUNCTION [dbo].[Split] (@sep VARCHAR(32), @s VARCHAR(MAX))
RETURNS TABLE
AS
    RETURN
    (
        SELECT r.value('.','VARCHAR(MAX)') as Item
        FROM (SELECT CONVERT(XML, N'<root><r>' + REPLACE(REPLACE(REPLACE(@s,'& ','&amp; '),'<','&lt;'), @sep, '</r><r>') + '</r></root>') as valxml) x
        CROSS APPLY x.valxml.nodes('//root/r') AS RECORDS(r)
    )

Then you can invoke it using:

SELECT * FROM dbo.Split(' ', 'I hate bunnies')

Which returns:

-----------
|I        |
|---------|
|hate     |
|---------|
|bunnies  |
-----------

CREATE FUNCTION [dbo].[Split] (@sep VARCHAR(32), @s VARCHAR(MAX))
RETURNS TABLE
AS
    RETURN
    (
        SELECT r.value('.','VARCHAR(MAX)') as Item
        FROM (SELECT CONVERT(XML, N'<root><r>' + REPLACE(@s, @sep, '</r><r>') + '</r></root>') as valxml) x
        CROSS APPLY x.valxml.nodes('//root/r') AS RECORDS(r)
    )

You have to use Javascript Filereader for this. (Introduction into filereader-api: http://www.html5rocks.com/en/tutorials/file/dndfiles/)

Once the user have choose a image you can read the file-path of the chosen image and place it into your html.

Example:

<form id="form1" runat="server">
    <input type='file' id="imgInp" />
    <img id="blah" src="#" alt="your image" />
</form>

Javascript:

function readURL(input) {
    if (input.files && input.files[0]) {
        var reader = new FileReader();

        reader.onload = function (e) {
            $('#blah').attr('src', e.target.result);
        }

        reader.readAsDataURL(input.files[0]);
    }
}

$("#imgInp").change(function(){
    readURL(this);
});

SHOW TABLES only lists the non-TEMPORARY tables in a given database.

https://dev.mysql.com/doc/refman/5.0/en/show-tables.html

This one worked like a charm for me where the date picker just has previous and next buttons and Month and year as texts.

Page objects are as follows

    [FindsBy(How =How.ClassName, Using = "ui-datepicker-calendar")]
    public IWebElement tblCalendar;

    [FindsBy(How = How.XPath, Using = "//a[@title=\"Prev\"]")]
    public IWebElement btnPrevious;

    [FindsBy(How = How.XPath, Using = "//a[@title=\"Next\"]")]
    public IWebElement btnNext;

    [FindsBy(How = How.ClassName, Using = "ui-datepicker-year")]
    public IWebElement lblYear;

    [FindsBy(How = How.ClassName, Using = "ui-datepicker-month")]
    public IWebElement lblMonth;



    public void SelectDateFromDatePicker(string year, string month, string date)
    {

        while (year != lblYear.Text)
        {
            if (int.Parse(year) < int.Parse(lblYear.Text))
            {
                btnPrevious.Clicks();
            }
            else
            {
                btnNext.Clicks();
            }
        }

        while (lblMonth.Text != "January")
        {
            btnPrevious.Clicks();
        }

        while (month != lblMonth.Text)
        {
               btnNext.Clicks();
        }

        IWebElement dateField = PropertiesCollection.driver.FindElement(By.XPath("//a[text()=\""+ date+"\"]"));
        dateField.Clicks();
    }

These are really two questions.

The first one is answered here: Calling a Sub in VBA

To the second one, protip: there is no main subroutine in VBA. Forget procedural, general-purpose languages. VBA subs are "macros" - you can run them by hitting Alt+F8 or by adding a button to your worksheet and calling up the sub you want from the automatically generated "ButtonX_Click" sub.

Besides the usual recommendation:

1. Drop index for bulk insert.
2. Batch inserts/updates in large transactions.
3. Tune your buffer cache/disable journal /w PRAGMAs.
4. Use a 64bit machine (to be able to use lots of cache™).
5. [added July 2014] Use common table expression (CTE) instead of running multiple SQL queries! Requires SQLite release 3.8.3.

I have learnt the following from my experience with SQLite3:

1. For maximum insert speed, don't use schema with any column constraint. (Alter table later as needed You can't add constraints with ALTER TABLE).
2. Optimize your schema to store what you need. Sometimes this means breaking down tables and/or even compressing/transforming your data before inserting to the database. A great example is to storing IP addresses as (long) integers.
3. One table per db file - to minimize lock contention. (Use ATTACH DATABASE if you want to have a single connection object.
4. SQLite can store different types of data in the same column (dynamic typing), use that to your advantage.

Question/comment welcome. ;-)

In java8, I would use the Instant class which is already in UTC and is convenient to work with.

import java.time.Instant;

Instant ins = Instant.now();
long ts = ins.toEpochMilli();

Instant ins2 = Instant.ofEpochMilli(ts)

Alternatively, you can use the following:

import java.time.*;

Instant ins = Instant.now(); 

OffsetDateTime odt = ins.atOffset(ZoneOffset.UTC);
ZonedDateTime zdt = ins.atZone(ZoneId.of("UTC"));

Back to Instant

Instant ins4 = Instant.from(odt);

Yes it is very easy to use, but you need to load javascript file in browser by script tag

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

and then user in js file like

var moduel = require('./module');

I am making a app using electron and it works as expected.

#include? should work, it works for general objects, not only strings. Your problem in example code is this test:

unless @suggested_horses.exists?(horse.id)
  @suggested_horses<< horse
end

(even assuming using #include?). You try to search for specific object, not for id. So it should be like this:

unless @suggested_horses.include?(horse)
  @suggested_horses << horse
end

ActiveRecord has redefined comparision operator for objects to take a look only for its state (new/created) and id

Please check that you have <?PHP at the top of your code. If you forget it, this error will appear.

Alternatives

• CSV: Super simple format (read & write)
• JSON: Nice for writing human-readable data; VERY commonly used (read & write)
• YAML: YAML is a superset of JSON, but easier to read (read & write, comparison of JSON and YAML)
• pickle: A Python serialization format (read & write)
• MessagePack (Python package): More compact representation (read & write)
• HDF5 (Python package): Nice for matrices (read & write)
• XML: exists too *sigh* (read & write)

For your application, the following might be important:

• Support by other programming languages
• Reading / writing performance
• Compactness (file size)

1. centralize all cookies in a single domain, let's say cookiemaker.com
2. when the user makes a request to example.com you redirect him to cookiemaker.com
3. cookiemaker.com redirects him back to example.com with the information you need

Of course, it's not completely secure, and you have to create some kind of internal protocol between your apps to do that.

Lastly, it would be very annoying for the user if you do something like that in every request, but not if it's just the first.

But I think there is no other way...
