A bit late to the party, but nevertheless...

I've been using JarBrowser to find in which jar a particular class is present. It's got an easy to use GUI which allows you to browse through the contents of all the jars in the selected path.

Is this perhaps what you are looking for?

I just made an imageCrop and Upload feature with

https://www.npmjs.com/package/react-image-crop

to get the ImagePreview ( the cropped image rendering in a canvas)

https://developer.mozilla.org/en-US/docs/Web/API/HTMLCanvasElement/toBlob

canvas.toBlob(function(blob){...}, 'image/jpeg', 0.95);

I prefer sending data in blob with content type image/jpeg rather than toDataURL ( a huge base64 string`

My implementation for uploading to Azure Blob using SAS URL

axios.post(azure_sas_url, image_in_blob, {
   headers: {
      'x-ms-blob-type': 'BlockBlob',
      'Content-Type': 'image/jpeg'
   }
})

It's very simple. Just Set width of img to 100%

I achieved satisfying results with:

min-height: 100%;
min-width: 100%;

this way you always maintain the aspect ratio.

The complete css for an image that will replace "object-fit: cover;":

width: auto;
height: auto;
min-width: 100%;
min-height: 100%;
position: absolute;
right: 50%;
transform: translate(50%, 0);

From the official Swift programming guide:

Global variables are variables that are defined outside of any function, method, closure, or type context. Global constants and variables are always computed lazily.

You can define it in any file and can access it in current module anywhere. So you can define it somewhere in the file outside of any scope. There is no need for static and all global variables are computed lazily.

 var yourVariable = "someString"

You can access this from anywhere in the current module.

However you should avoid this as Global variables are not good for application state and mainly reason of bugs.

As shown in this answer, in Swift you can encapsulate them in struct and can access anywhere. You can define static variables or constant in Swift also. Encapsulate in struct

struct MyVariables {
    static var yourVariable = "someString"
}

You can use this variable in any class or anywhere

let string = MyVariables.yourVariable
println("Global variable:\(string)")

//Changing value of it
MyVariables.yourVariable = "anotherString"

you can use getopt to handle parameters in your bash script. there are not many explanations for getopt out there. here is an example:

#!/bin/sh

OPTIONS=$(getopt -o hf:gb -l help,file:,foo,bar -- "$@")

if [ $? -ne 0 ]; then
  echo "getopt error"
  exit 1
fi

eval set -- $OPTIONS

while true; do
  case "$1" in
    -h|--help) HELP=1 ;;
    -f|--file) FILE="$2" ; shift ;;
    -g|--foo)  FOO=1 ;;
    -b|--bar)  BAR=1 ;;
    --)        shift ; break ;;
    *)         echo "unknown option: $1" ; exit 1 ;;
  esac
  shift
done

if [ $# -ne 0 ]; then
  echo "unknown option(s): $@"
  exit 1
fi

echo "help: $HELP"
echo "file: $FILE"
echo "foo: $FOO"
echo "bar: $BAR"

If you need to join xpath-selected text nodes but can not use string-join (when you are stuck with XSL 1.0) this might help:

<xsl:variable name="x">
    <xsl:apply-templates select="..." mode="string-join-mode"/>
</xsl:variable>
joined and normalized: <xsl:value-of select="normalize-space($x)"/>

<xsl:template match="*" mode="string-join-mode">
    <xsl:apply-templates mode="string-join-mode"/>
</xsl:template>    

<xsl:template match="text()" mode="string-join-mode">
    <xsl:value-of select="."/>
</xsl:template>    

In the Window menu, open Show View -> Other ... and type log to find it.

The argument to remove() is a filter document, so passing in an empty document means 'remove all':

db.user.remove({})

However, if you definitely want to remove everything you might be better off dropping the collection. Though that probably depends on whether you have user defined indexes on the collection i.e. whether the cost of preparing the collection after dropping it outweighs the longer duration of the remove() call vs the drop() call.

More details in the docs.

If you do not specifically need the alt text of an image, then you can just target the class/id of the image.

$('img.propImg').each(function(){ 
     enter code here
}

I know it’s not quite answering the question, though I’d spent ages trying to figure this out and this question gave me the solution :). In my case I needed to hide any image tags with a specific src.

$('img.propImg').each(function(){ //for each loop that gets all the images. 
        if($(this).attr('src') == "img/{{images}}") { // if the src matches this
        $(this).css("display", "none") // hide the image.
    }
});

Here's what I ended up with. It's a listing of all properties and methods, and I listed all parameters for each method. I didn't succeed on getting all of the values.

foreach(System.Reflection.AssemblyName an in System.Reflection.Assembly.GetExecutingAssembly().GetReferencedAssemblies()){                      
            System.Reflection.Assembly asm = System.Reflection.Assembly.Load(an.ToString());
            foreach(Type type in asm.GetTypes()){   
                //PROPERTIES
                foreach (System.Reflection.PropertyInfo property in type.GetProperties()){
                    if (property.CanRead){
                        Response.Write("<br>" + an.ToString() + "." + type.ToString() + "." + property.Name);       
                    }
                }
                //METHODS
                var methods = type.GetMethods();
                foreach (System.Reflection.MethodInfo method in methods){               
                    Response.Write("<br><b>" + an.ToString() + "."  + type.ToString() + "." + method.Name  + "</b>");

                    {
                        Response.Write("<br><i>Param=" + param.Name.ToString());
                        Response.Write("<br>  Type=" + param.ParameterType.ToString());
                        Response.Write("<br>  Position=" + param.Position.ToString());
                        Response.Write("<br>  Optional=" + param.IsOptional.ToString() + "</i>");
                    }
                }
            }
        }

driver.find_element_by_id('foo').clear()

columnDefinition will override the sql DDL generated by hibernate for this particular column, it is non portable and depends on what database you are using. You can use it to specify nullable, length, precision, scale... ect.

Use

implementation 'com.android.support:appcompat-v7:27.1.1'

Don't use like

implementation 'com.android.support:appcompat-v7:27.+'

It may give you an error and don't use an older version than this.

or event don't do like this

implementation 'com.android.support:appcompat-v7:27.1.1'
implementation 'com.android.support:design:27.1.1' 

etc... numbers of libraries and then

implementation 'com.android.support:appcompat-v7:27.+'

the same library but it has a different version, it can give you an error.

Objects in JavaScript are collections of unordered properties. Objects are hashtables.

If you want your properties to be in alphabetical order, one possible solution would be to create an index for your properties in a separate array. Just a few hours ago, I answered a question on Stack Overflow which you may want to check out:

• Iterating over a JavaScript object in sort order based on particular key value of a child object

Here's a quick adaptation for your object¹:

var obj = {
    "set1": [1, 2, 3],
    "set2": [4, 5, 6, 7, 8],
    "set3": [9, 10, 11, 12]
};

var index = [];

// build the index
for (var x in obj) {
   index.push(x);
}

// sort the index
index.sort(function (a, b) {    
   return a == b ? 0 : (a > b ? 1 : -1); 
}); 

Then you would be able to do the following:

console.log(obj[index[1]]);

The answer I cited earlier proposes a reusable solution to iterate over such an object. That is unless you can change your JSON to as @Jacob Relkin suggested in the other answer, which could be easier.

¹ You may want to use the hasOwnProperty() method to ensure that the properties belong to your object and are not inherited from Object.prototype.

I'm having a similar issue.

I found

conda install pyodbc

is wrong!

when I use

apt-get install python-pyodbc

I solved this problem?

If working on EJB client library:

You need to mention the argument for getting the initial context.

InitialContext ctx = new InitialContext();

If you do not, it will look in the project folder for properties file. Also you can include the properties credentials or values in your class file itself as follows:

Properties props = new Properties();
props.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory");
props.put(Context.URL_PKG_PREFIXES, "org.jboss.ejb.client.naming");
props.put(Context.PROVIDER_URL, "jnp://localhost:1099");

InitialContext ctx = new InitialContext(props);

URL_PKG_PREFIXES: Constant that holds the name of the environment property for specifying the list of package prefixes to use when loading in URL context factories.

The EJB client library is the primary library to invoke remote EJB components.
This library can be used through the InitialContext. To invoke EJB components the library creates an EJB client context via a URL context factory. The only necessary configuration is to parse the value org.jboss.ejb.client.naming for the java.naming.factory.url.pkgs property to instantiate an InitialContext.

I went ahead and downloaded the project from the link you provided: http://javapapers.com/android/android-chat-bubble/

Since this is an old tutorial, you simply need to upgrade the software, gradle, the android build tools and plugin.

Make sure you have the latest Gradle and Android Studio:

• https://www.gradle.org/
• http://tools.android.com/tech-docs/new-build-system/version-compatibility

build.gradle:

buildscript {
    repositories {
        jcenter()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:2.1.2'
    }
}

allprojects {
    repositories {
        jcenter()
    }
}

app/build.gradle:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 23
    buildToolsVersion '23.0.3'

    defaultConfig {
        minSdkVersion 9
        targetSdkVersion 23
        versionCode 1
        versionName '1.0'
    }
}

dependencies {
    compile 'com.android.support:appcompat-v7:23.2.1'
}

Then run gradle:

gradle installDebug

Under Windows only: You may try to use ini_set() function^Docs for the SMTP^Docs and smtp_port^Docs settings:

ini_set('SMTP', 'mysmtphost'); 
ini_set('smtp_port', 25); 

Based on David's answer I personally like to check the given object first if it is a string at all. Otherwise calling .trim() on a not existing object would throw an exception:

function isEmpty(value) {
  return typeof value == 'string' && !value.trim() || typeof value == 'undefined' || value === null;
}

Usage:

isEmpty(undefined); // true
isEmpty(null); // true
isEmpty(''); // true
isEmpty('foo'); // false
isEmpty(1); // false
isEmpty(0); // false

Use the join method from the Array type.

a.value = [a, b, c, d, e, f];
var stringValueYouWant = a.join();

The join method will return a string that is the concatenation of all the array elements. It will use the first parameter you pass as a separator - if you don't use one, it will use the default separator, which is the comma.

I would give a min-height and min-width to your overlay div of the size of the image, and change the background color on hover

.overlay { position: absolute; top: 0; left: 0;  z-index: 200; min-height:200px; min-width:200px; background-color: none;}
.overlay:hover { background-color: red;}

In my case, this error was caused by a db.close(); out of a 'await' section inside of 'async'

MongoClient.connect(url, {poolSize: 10, reconnectTries: Number.MAX_VALUE, reconnectInterval: 1000}, function(err, db) {
    // Validate the connection to Mongo
    assert.equal(null, err);    
    // Query the SQL table 
    querySQL()
    .then(function (result) {
        console.log('Print results SQL');
        console.log(result);
        if(result.length > 0){

            processArray(db, result)
            .then(function (result) {
                console.log('Res');
                console.log(result);
            })
            .catch(function (err) {
                console.log('Err');
                console.log(err);
            })
        } else {
            console.log('Nothing to show in MySQL');
        }
    })
    .catch(function (err) {
        console.log(err);
    });
    db.close(); // <--------------------------------THIS LINE
});

This problem might occur if you are behind corporate proxy and corporation uses its own certificate. Just add "--no-check-certificate" in the command. e.g. wget --no-check-certificate -qO - http://pkg.jenkins-ci.org/debian/jenkins-ci.org.key | sudo apt-key add -

It works. If you want to see what is going on, you can use verbose command instead of quiet before adding "--no-check-certificate" option. e.g. wget -vO - http://pkg.jenkins-ci.org/debian/jenkins-ci.org.key | sudo apt-key add - This will tell you to use "--no-check-certificate" if you are behind proxy.

Three alternative solutions:

1) With data.table:

You can use the same melt function as in the reshape2 package (which is an extended & improved implementation). melt from data.table has also more parameters that the melt-function from reshape2. You can for example also specify the name of the variable-column:

library(data.table)
long <- melt(setDT(wide), id.vars = c("Code","Country"), variable.name = "year")

which gives:

> long
    Code     Country year  value
 1:  AFG Afghanistan 1950 20,249
 2:  ALB     Albania 1950  8,097
 3:  AFG Afghanistan 1951 21,352
 4:  ALB     Albania 1951  8,986
 5:  AFG Afghanistan 1952 22,532
 6:  ALB     Albania 1952 10,058
 7:  AFG Afghanistan 1953 23,557
 8:  ALB     Albania 1953 11,123
 9:  AFG Afghanistan 1954 24,555
10:  ALB     Albania 1954 12,246

Some alternative notations:

melt(setDT(wide), id.vars = 1:2, variable.name = "year")
melt(setDT(wide), measure.vars = 3:7, variable.name = "year")
melt(setDT(wide), measure.vars = as.character(1950:1954), variable.name = "year")

2) With tidyr:

library(tidyr)
long <- wide %>% gather(year, value, -c(Code, Country))

Some alternative notations:

wide %>% gather(year, value, -Code, -Country)
wide %>% gather(year, value, -1:-2)
wide %>% gather(year, value, -(1:2))
wide %>% gather(year, value, -1, -2)
wide %>% gather(year, value, 3:7)
wide %>% gather(year, value, `1950`:`1954`)

3) With reshape2:

library(reshape2)
long <- melt(wide, id.vars = c("Code", "Country"))

Some alternative notations that give the same result:

# you can also define the id-variables by column number
melt(wide, id.vars = 1:2)

# as an alternative you can also specify the measure-variables
# all other variables will then be used as id-variables
melt(wide, measure.vars = 3:7)
melt(wide, measure.vars = as.character(1950:1954))

NOTES:

• reshape2 is retired. Only changes necessary to keep it on CRAN will be made. (source)
• If you want to exclude NA values, you can add na.rm = TRUE to the melt as well as the gather functions.

Another problem with the data is that the values will be read by R as character-values (as a result of the , in the numbers). You can repair that with gsub and as.numeric:

long$value <- as.numeric(gsub(",", "", long$value))

Or directly with data.table or dplyr:

# data.table
long <- melt(setDT(wide),
             id.vars = c("Code","Country"),
             variable.name = "year")[, value := as.numeric(gsub(",", "", value))]

# tidyr and dplyr
long <- wide %>% gather(year, value, -c(Code,Country)) %>% 
  mutate(value = as.numeric(gsub(",", "", value)))

Data:

wide <- read.table(text="Code Country        1950    1951    1952    1953    1954
AFG  Afghanistan    20,249  21,352  22,532  23,557  24,555
ALB  Albania        8,097   8,986   10,058  11,123  12,246", header=TRUE, check.names=FALSE)

A canvas element with some JavaScript would work great.

In fact, Signature Pad (a jQuery plugin) already has this implemented.

Simply use eval function.

var myJson = eval(theJsibStr);

Here's what I eventually came up with to print the first n primes:

numprimes = raw_input('How many primes to print?  ')
count = 0
potentialprime = 2

def primetest(potentialprime):
    divisor = 2
    while divisor <= potentialprime:
        if potentialprime == 2:
            return True
        elif potentialprime % divisor == 0:
            return False
            break
        while potentialprime % divisor != 0:
            if potentialprime - divisor > 1:
                divisor += 1
            else:
                return True

while count < int(numprimes):
    if primetest(potentialprime) == True:
        print 'Prime #' + str(count + 1), 'is', potentialprime
        count += 1
        potentialprime += 1
    else:
        potentialprime += 1

step 1: add

<asp:FileUpload runat="server" id="fileUpload1" Multiple="Multiple">
    </asp:FileUpload>

step 2: add

Protected Sub uploadBtn_Click(sender As Object, e As System.EventArgs) Handles uploadBtn.Click
    Dim ImageFiles As HttpFileCollection = Request.Files
    For i As Integer = 0 To ImageFiles.Count - 1
        Dim file As HttpPostedFile = ImageFiles(i)
        file.SaveAs(Server.MapPath("Uploads/") & ImageFiles(i).FileName)
    Next

End Sub

All the previous solutions seem to be overly complicated for what I think you need, and often didn't work for me. The following one-line command does what you want:

import os
ROOT_DIR = os.path.abspath(os.curdir)

Sub don't return values and functions don't have side effects.

Sometimes you want both side effect and return value.

This is easy to be done once you know that VBA passes arguments by default by reference so you can write your code in this way:

Sub getValue(retValue as Long)
    ...
    retValue = 42 
End SUb 

Sub Main()
    Dim retValue As Long
    getValue retValue 
    ... 
End SUb

http://locomotivejs.org/ provides a way to structure an app built with Node.js and Express.

From the website:

"Locomotive is a web framework for Node.js. Locomotive supports MVC patterns, RESTful routes, and convention over configuration, while integrating seamlessly with any database and template engine. Locomotive builds on Express, preserving the power and simplicity you've come to expect from Node."

If you want to sort based on first column (which contains number value), then try this:

arr.sort(function(a,b){
  return a[0]-b[0]
})

If you want to sort based on second column (which contains string value), then try this:

arr.sort(function(a,b){
  return a[1].charCodeAt(0)-b[1].charCodeAt(0)
})

P.S. for the second case, you need to compare between their ASCII values.

Hope this helps.

Assign something to your strings. This will definitely help.

You can do this by setting the display to 'table-cell' and applying a vertical-align: middle;:

    {
        display: table-cell;
        vertical-align: middle;
    }

This is however not supported by all versions of Internet Explorer according to this excerpt I copied from http://www.w3schools.com/cssref/pr_class_display.asp without permission.

Note: The values "inline-table", "table", "table-caption", "table-cell", "table-column", "table-column-group", "table-row", "table-row-group", and "inherit" are not supported by Internet Explorer 7 and earlier. Internet Explorer 8 requires a !DOCTYPE. Internet Explorer 9 supports the values.

The following table shows the allowed display values also from http://www.w3schools.com/cssref/pr_class_display.asp.

It's the same. Your international format is already correct, and is recommended for use in all cases, where possible.

function removeParam(parameter)
{
  var url=document.location.href;
  var urlparts= url.split('?');

 if (urlparts.length>=2)
 {
  var urlBase=urlparts.shift(); 
  var queryString=urlparts.join("?"); 

  var prefix = encodeURIComponent(parameter)+'=';
  var pars = queryString.split(/[&;]/g);
  for (var i= pars.length; i-->0;)               
      if (pars[i].lastIndexOf(prefix, 0)!==-1)   
          pars.splice(i, 1);
  url = urlBase+'?'+pars.join('&');
  window.history.pushState('',document.title,url); // added this line to push the new url directly to url bar .

}
return url;
}

This will resolve your problem

Put the control you want to bring to front at the end of your xaml code. I.e.

<Grid>
  <TabControl ...>
  </TabControl>
  <Button Content="ALways on top of TabControl Button"/>
</Grid>

Add this to your css:

.row-centered {
   text-align:center;
}


.col-centered {
   display:inline-block;
   float:none;
   /* reset the text-align */
   text-align:left;
   /* inline-block space fix */
   margin-right:-4px;
}

Then, in your HTML code:

    <div class=" row row-centered">
        <div class="col-*-*  col-centered>
           Your content
        </div>
    </div>

In Java 8 :

    List<String> players = new ArrayList<>();
     players.forEach(System.out::println);

They are not the same.

Undeclared variable (without var) are treated as properties of the global object. (Usually the window object, unless you're in a with block)

Variables declared with var are normal local variables, and are not visible outside the function they're declared in. (Note that Javascript does not have block scope)

Update: ECMAScript 2015

let was introduced in ECMAScript 2015 to have block scope.

They're the same thing. A URI is a generalization of a URL. Originally, URIs were planned to be divided into URLs (addresses) and URNs (names) but then there was little difference between a URL and URI and http URIs were used as namespaces even though they didn't actually locate any resources.

with string GMT/UTC +/-0400 or GMT/UTC +/-1000 based on local timings

Your custom format is just missing O to give you the timezone offsets from local time.

Difference to Greenwich time (GMT) in hours Example: +0200

date_default_timezone_set('America/La_Paz');
echo date('Y-m-d H:i:s O');

2018-01-12 12:10:11 -0400

However, for maximized portability/interoperability, I would recommend using the ISO8601 date format c

date_default_timezone_set('America/La_Paz');
echo date('c');

2018-01-12T12:10:11-04:00

date_default_timezone_set('Australia/Brisbane');
echo date('c');

2018-01-13T02:10:11+10:00

You can use also gmdate and the timezone offset string will always be +00:00

date_default_timezone_set('America/La_Paz');
echo gmdate('c');

2018-01-12T16:10:11+00:00

date_default_timezone_set('Australia/Brisbane');
echo gmdate('c');

2018-01-12T16:10:11+00:00

You have to replace YourID and value="3" for your current ones.

$(document).ready(function() {_x000D_
  $('#YourID option[value="3"]').attr("selected", "selected");_x000D_
});

It is possible to do with CSS only by selecting active and focus pseudo element of the button.

button:active{
    background:olive;
}

button:focus{
    background:olive;
}

See codepen: http://codepen.io/fennefoss/pen/Bpqdqx

You could also write a simple jQuery click function which changes the background color.

HTML:

<button class="js-click">Click me!</button>

CSS:

button {
  background: none;
}

JavaScript:

  $( ".js-click" ).click(function() {
    $( ".js-click" ).css('background', 'green');
  });

Check out this codepen: http://codepen.io/fennefoss/pen/pRxrVG

Check if there is already a Node server running on your machine and then close it.

MyModel.objects.get(pk=1).delete()

this will raise exception if the object with specified primary key doesn't exist because at first it tries to retrieve the specified object.

MyModel.objects.filter(pk=1).delete()

this wont raise exception if the object with specified primary key doesn't exist and it directly produces the query

DELETE FROM my_models where id=1

You can use the StringUtils class in Apache Commons:

StringUtils.substringAfterLast(one, "-");

In modern browsers you can do:

.reMode_hover:not(.reMode_selected):hover{}

Solution With Less XAML and More C#

If you define the ListView in XAML:

<ListView x:Name="listView"/>

Then you can add columns and populate it in C#:

public Window()
{
    // Initialize
    this.InitializeComponent();

    // Add columns
    var gridView = new GridView();
    this.listView.View = gridView;
    gridView.Columns.Add(new GridViewColumn { 
        Header = "Id", DisplayMemberBinding = new Binding("Id") });
    gridView.Columns.Add(new GridViewColumn { 
        Header = "Name", DisplayMemberBinding = new Binding("Name") });

    // Populate list
    this.listView.Items.Add(new MyItem { Id = 1, Name = "David" });
}

See definition of MyItem below.

Solution With More XAML and less C#

However, it's easier to define the columns in XAML (inside the ListView definition):

<ListView x:Name="listView">
    <ListView.View>
        <GridView>
            <GridViewColumn Header="Id" DisplayMemberBinding="{Binding Id}"/>
            <GridViewColumn Header="Name" DisplayMemberBinding="{Binding Name}"/>
        </GridView>
    </ListView.View>
</ListView>

And then just populate the list in C#:

public Window()
{
    // Initialize
    this.InitializeComponent();

    // Populate list
    this.listView.Items.Add(new MyItem { Id = 1, Name = "David" });
}

See definition of MyItem below.

MyItem Definition

MyItem is defined like this:

public class MyItem
{
    public int Id { get; set; }

    public string Name { get; set; }
}

As of ASP.NET MVC 5.1, adding a class to an EditorFor is possible (the original question specified ASP.NET MVC 3, and the accepted answer is still the best with that considered).

@Html.EditorFor(x=> x.MyProperty,
    new { htmlAttributes = new { @class = "MyCssClass" } })

See: What's New in ASP.NET MVC 5.1, Bootstrap support for editor templates

In my case it was due to 'lower_case_table_names' parameter.

The error number 39 thrown out when I tried to drop the databases which consists upper case table names with lower_case_table_names parameter is enabled.

This is fixed by reverting back the lower case parameter changes to the previous state.

if your table is like this

rowId     col1    col2    col3    col4
 1          a       e       12       2
 2          b       f       42       5
 3          a       e       32       2
 4          b       f       44       5


var grouped = myTable.AsEnumerable().GroupBy(r=> new {pp1 =  r.Field<int>("col1"), pp2 = r.Field<int>("col2")});

Well Facebook has undergone MANY many changes and it wasn't originally designed to be efficient. It was designed to do it's job. I have absolutely no idea what the code looks like and you probably won't find much info about it (for obvious security and copyright reasons), but just take a look at the API. Look at how often it changes and how much of it doesn't work properly, anymore, or at all.

I think the biggest ace up their sleeve is the Hiphop. http://developers.facebook.com/blog/post/358 You can use HipHop yourself: https://github.com/facebook/hiphop-php/wiki

But if you ask me it's a very ambitious and probably time wasting task. Hiphop only supports so much, it can't simply convert everything to C++. So what does this tell us? Well, it tells us that Facebook is NOT fully taking advantage of the PHP language. It's not using the latest 5.3 and I'm willing to bet there's still a lot that is PHP 4 compatible. Otherwise, they couldn't use HipHop. HipHop IS A GOOD IDEA and needs to grow and expand, but in it's current state it's not really useful for that many people who are building NEW PHP apps.

There's also PHP to JAVA via things like Resin/Quercus. Again, it doesn't support everything...

Another thing to note is that if you use any non-standard PHP module, you aren't going to be able to convert that code to C++ or Java either. However...Let's take a look at PHP modules. They are ARE compiled in C++. So if you can build PHP modules that do things (like parse XML, etc.) then you are basically (minus some interaction) working at the same speed. Of course you can't just make a PHP module for every possible need and your entire app because you would have to recompile and it would be much more difficult to code, etc.

However...There are some handy PHP modules that can help with speed concerns. Though at the end of the day, we have this awesome thing known as "the cloud" and with it, we can scale our applications (PHP included) so it doesn't matter as much anymore. Hardware is becoming cheaper and cheaper. Amazon just lowered it's prices (again) speaking of.

So as long as you code your PHP app around the idea that it will need to one day scale...Then I think you're fine and I'm not really sure I'd even look at Facebook and what they did because when they did it, it was a completely different world and now trying to hold up that infrastructure and maintain it...Well, you get things like HipHop.

Now how is HipHop going to help you? It won't. It can't. You're starting fresh, you can use PHP 5.3. I'd highly recommend looking into PHP 5.3 frameworks and all the new benefits that PHP 5.3 brings to the table along with the SPL libraries and also think about your database too. You're most likely serving up content from a database, so check out MongoDB and other types of databases that are schema-less and document-oriented. They are much much faster and better for the most "common" type of web site/app.

Look at NEW companies like Foursquare and Smugmug and some other companies that are utilizing NEW technology and HOW they are using it. For as successful as Facebook is, I honestly would not look at them for "how" to build an efficient web site/app. I'm not saying they don't have very (very) talented people that work there that are solving (their) problems creatively...I'm also not saying that Facebook isn't a great idea in general and that it's not successful and that you shouldn't get ideas from it....I'm just saying that if you could view their entire source code, you probably wouldn't benefit from it.

Solved this by adding following

RewriteCond %{ENV:REDIRECT_STATUS} 200 [OR]
 RewriteCond %{REQUEST_FILENAME} -f [OR]
 RewriteCond %{REQUEST_FILENAME} -d
 RewriteRule ^ - [L]

In Eclipse Kepler it is very easy to generate Web Service Client classes,You can achieve this by following steps .

RightClick on any Project->Create New Other ->Web Services->Web Service Client->Then paste the wsdl url(or location) in Service Definition->Next->Finish

You will see the generated classes are inside your src folder.

NOTE :Without eclipse also you can generate client classes from wsdl file by using wsimport command utility which ships with JDK.

refer this link Create Web service client using wsdl

You coud try java.net.URLClassloader with the url of the folder/jar where your updated class resides and use it instead of the default classloader when creating a new thread.

You can also do

console.log("a = %o, b = %o", a, b);

where a and b are objects.

I found I needed to enable the SSL module in Apache (obviously prefix commands with sudo if you are not running as root):

a2enmod ssl

then restart Apache:

/etc/init.d/apache2 restart

More details of SSL in Apache for Ubuntu / Debian here.

In my case clicking the checkbox for 'import project into workspace' fixed the error, even though the project was already in the workspace folder and didn't actually get moved their by eclipse.

If you're using JNA, you can do thisPlatform.is64Bit().

Important: Unless you have a very particular use-case, do not encrypt passwords, use a password hashing algorithm instead. When someone says they encrypt their passwords in a server-side application, they're either uninformed or they're describing a dangerous system design. Safely storing passwords is a totally separate problem from encryption.

Be informed. Design safe systems.

Portable Data Encryption in PHP

If you're using PHP 5.4 or newer and don't want to write a cryptography module yourself, I recommend using an existing library that provides authenticated encryption. The library I linked relies only on what PHP provides and is under periodic review by a handful of security researchers. (Myself included.)

If your portability goals do not prevent requiring PECL extensions, libsodium is highly recommended over anything you or I can write in PHP.

Update (2016-06-12): You can now use sodium_compat and use the same crypto libsodium offers without installing PECL extensions.

If you want to try your hand at cryptography engineering, read on.

First, you should take the time to learn the dangers of unauthenticated encryption and the Cryptographic Doom Principle.

• Encrypted data can still be tampered with by a malicious user.
• Authenticating the encrypted data prevents tampering.
• Authenticating the unencrypted data does not prevent tampering.

Encryption and Decryption

Encryption in PHP is actually simple (we're going to use openssl_encrypt() and openssl_decrypt() once you have made some decisions about how to encrypt your information. Consult openssl_get_cipher_methods() for a list of the methods supported on your system. The best choice is AES in CTR mode:

• aes-128-ctr
• aes-192-ctr
• aes-256-ctr

There is currently no reason to believe that the AES key size is a significant issue to worry about (bigger is probably not better, due to bad key-scheduling in the 256-bit mode).

Note: We are not using mcrypt because it is abandonware and has unpatched bugs that might be security-affecting. Because of these reasons, I encourage other PHP developers to avoid it as well.

    public static function encrypt($message, $key, $encode = false)
    {
        $nonceSize = openssl_cipher_iv_length(self::METHOD);
        $nonce = openssl_random_pseudo_bytes($nonceSize);

        $ciphertext = openssl_encrypt(

        }
        return $nonce.$ciphertext;

        }

        $nonceSize = openssl_cipher_iv_length(self::METHOD);
        $nonce = mb_substr($message, 0, $nonceSize, '8bit');

Usage Example

$message = 'Ready your ammunition; we attack at dawn.';
$key = hex2bin('000102030405060708090a0b0c0d0e0f101112131415161718191a1b1c1d1e1f');

$encrypted = UnsafeCrypto::encrypt($message, $key);
$decrypted = UnsafeCrypto::decrypt($encrypted, $key);

var_dump($encrypted, $decrypted);

Demo: https://3v4l.org/jl7qR

The above simple crypto library still is not safe to use. We need to authenticate ciphertexts and verify them before we decrypt.

Note: By default, UnsafeCrypto::encrypt() will return a raw binary string. Call it like this if you need to store it in a binary-safe format (base64-encoded):

$message = 'Ready your ammunition; we attack at dawn.';
$key = hex2bin('000102030405060708090a0b0c0d0e0f101112131415161718191a1b1c1d1e1f');

$encrypted = UnsafeCrypto::encrypt($message, $key, true);
$decrypted = UnsafeCrypto::decrypt($encrypted, $key, true);

If anyone wishes to use this SaferCrypto library in a production environment, or your own implementation of the same concepts, I strongly recommend reaching out to your resident cryptographers for a second opinion before you do. They'll be able tell you about mistakes that I might not even be aware of.

You will be much better off using a reputable cryptography library.

The Swift 4 solution I use, takes in keyboard size. Replace serverStatusStackView with whatever view you care about, e.g.: self.view:

deinit {
    NotificationCenter.default.removeObserver(self)
}

@objc func keyboardWillShow(notification: NSNotification) {
    if let keyboardSize = (notification.userInfo?[UIKeyboardFrameBeginUserInfoKey] as? NSValue)?.cgRectValue {
        serverStatusStackView.frame.origin.y = keyboardSize.height * 2 - serverStatusStackView.frame.height
    }
}

@objc func keyboardWillHide(notification: NSNotification) {
    if let keyboardSize = (notification.userInfo?[UIKeyboardFrameBeginUserInfoKey] as? NSValue)?.cgRectValue {
        serverStatusStackView.frame.origin.y += keyboardSize.height
    }
}

override func viewDidLoad() {
    super.viewDidLoad()
    NotificationCenter.default.addObserver(self, selector: #selector(keyboardWillShow(notification:)), name: NSNotification.Name.UIKeyboardWillShow, object: nil)

    NotificationCenter.default.addObserver(self, selector: #selector(keyboardWillHide(notification:)), name: NSNotification.Name.UIKeyboardWillHide, object: nil)
}

I came across the join() while learning about race condition and I will clear the doubts I was having. So let us take this small example

Thread t2 = new Thread(
             new Runnable() {
                 public void run () {
                     //do something
                 }
              }
);
Thread t1 = new Thread(
             new Runnable() {
                 public void run () {
                     //do something
                 }
              }
);
t2.start(); //Line 11
t1.start(); //Line 12
t2.join();  //Line 13
t1.join();  //Line 14
System.out.print("<Want to print something that was being modified by t2 and t1>")

My AIM
Three threads are running namely t1, t2 and the main thread. I want to print something after the t1 and t2 has finished. The printing operation is on my main thread therefore for the expected answer I need to let t1 and t2 finish and then print my output.

So t1.join() just makes the main thread wait, till the t1 thread completes before going to the next line in program.

Here is the definition as per GeeksforGeeks:

java.lang.Thread class provides the join() method which allows one thread to wait until another thread completes its execution.

Here is one question that might solve your doubt

Q-> Will t1 thread get the time slice to run by the thread scheduler, when the program is processing the t2.join() at Line 13?

ANS-> Yes it will be eligible to get the time slice to run as we have already made it eligible by running the line t1.start() at Line 11.
t2.join() only applies the condition when the JVM will go to next line, that is Line 14.
It might be also possible that t1 might get finished processing at Line 13.

String[] split = data.split("\\|",-1);

This is not the actual requirement in all the time. The Drawback of above is show below:

Scenerio 1:
When all data are present:
    String data = "5|6|7||8|9|10|";
    String[] split = data.split("\\|");
    String[] splt = data.split("\\|",-1);
    System.out.println(split.length); //output: 7
    System.out.println(splt.length); //output: 8

When data is missing:

Scenerio 2: Data Missing
    String data = "5|6|7||8|||";
    String[] split = data.split("\\|");
    String[] splt = data.split("\\|",-1);
    System.out.println(split.length); //output: 5
    System.out.println(splt.length); //output: 8

Real requirement is length should be 7 although there is data missing. Because there are cases such as when I need to insert in database or something else. We can achieve this by using below approach.

    String data = "5|6|7||8|||";
    String[] split = data.split("\\|");
    String[] splt = data.replaceAll("\\|$","").split("\\|",-1);
    System.out.println(split.length); //output: 5
    System.out.println(splt.length); //output:7

What I've done here is, I'm removing "|" pipe at the end and then splitting the String. If you have "," as a seperator then you need to add ",$" inside replaceAll.

You were close. You can do:

var element = $("#parentDiv").find(".myClassNameOfInterest");

• .find() - http://api.jquery.com/find

Alternatively, you can do:

var element = $(".myClassNameOfInterest", "#parentDiv");

...which sets the context of the jQuery object to the #parentDiv.

EDIT:

Additionally, it may be faster in some browsers if you do div.myClassNameOfInterest instead of just .myClassNameOfInterest.

I think the question makes it seem like the answer is simpler than it really is.

Running of pip will sometimes require native compilation of a module (64-bit NumPy is a common example of that). In order for pip's compilation to succeed, you need Python which was compiled with the same version of Microsoft Visual C++ as the one pip is using.

Standard Python distributions are compiled with Microsoft Visual C++ 2008. You can install an Express version of Microsoft Visual C++ 2008, but it is not maintained. Your best bet is to get an express version of a later Microsoft Visual C++ and compile Python. Then PIP and Python will be using the same Microsoft Visual C++ version.

I had used home-brew to install 2.7 on OS X 10.10 and the new install was missing the sym links. I ran

brew link --overwrite python

as mentioned in How to symlink python in Homebrew? and it solved the problem.

In cassandra , the difference between primary key,partition key,composite key, clustering key always makes some confusion.. So I am going to explain below and co relate to each others. We use CQL (Cassandra Query Language) for Cassandra database access. Note:- Answer is as per updated version of Cassandra. Primary Key :-

In cassandra there are 2 different way to use primary Key .

CREATE TABLE Cass (
    id int PRIMARY KEY,
    name text 
);

Create Table Cass (
   id int,
   name text,
   PRIMARY KEY(id) 
);

In CQL, the order in which columns are defined for the PRIMARY KEY matters. The first column of the key is called the partition key having property that all the rows sharing the same partition key (even across table in fact) are stored on the same physical node. Also, insertion/update/deletion on rows sharing the same partition key for a given table are performed atomically and in isolation. Note that it is possible to have a composite partition key, i.e. a partition key formed of multiple columns, using an extra set of parentheses to define which columns forms the partition key.

Partitioning and Clustering The PRIMARY KEY definition is made up of two parts: the Partition Key and the Clustering Columns. The first part maps to the storage engine row key, while the second is used to group columns in a row.

CREATE TABLE device_check (
  device_id   int,
  checked_at  timestamp,
  is_power    boolean,
  is_locked   boolean,
  PRIMARY KEY (device_id, checked_at)
);

Here device_id is partition key and checked_at is cluster_key.

We can have multiple cluster key as well as partition key too which depends on declaration.

The [0] needs to be inside the ).

Replacing forward(/) slash with backward(\) slash will do the job. The folder separator in Windows is \ not /

Use "$@" to represent all the arguments:

for var in "$@"
do
    echo "$var"
done

This will iterate over each argument and print it out on a separate line. $@ behaves like $* except that when quoted the arguments are broken up properly if there are spaces in them:

sh test.sh 1 2 '3 4'
1
2
3 4

Web Site = use when the website is created by graphic designers and the programmers only edit one or two pages

Web Application = use when the application is created by programmers and the graphic designers only edit one or two paged/images.

Web Sites can be worked on using any HTML tools without having to have developer studio, as project files don’t need to be updated, etc. Web applications are best when the team is mostly using developer studio and there is a high code content.

(Some coding errors are found in Web Applications at compile time that are not found in Web Sites until run time.)

Warning: I wrote this answer many years ago and have not used Asp.net since. I expect things have now moved on.

You could make a method:

public byte[] toBytes(char[] data) {
byte[] toRet = new byte[data.length];
for(int i = 0; i < toRet.length; i++) {
toRet[i] = (byte) data[i];
}
return toRet;
}

Hope this helps

I had faced a similar issue and this is what worked for me:

    string excelPath = Server.MapPath("~/Files/") + Path.GetFileName(FileUpload1.PostedFile.FileName);

    FileUpload1.SaveAs(excelPath);



    string conString = string.Empty;

    string extension = Path.GetExtension(FileUpload1.PostedFile.FileName);

    switch (extension)

    {

        case ".xls": //Excel 97-03

            conString = ConfigurationManager.ConnectionStrings["Excel03ConString"].ConnectionString;

The code I use with jQuery:

$("a.btn_external").click(function() {
    url_to_open = $(this).attr("href");
    window.open(url_to_open, '_blank');
    return false;
});

This is useful to distinguish between the click events of a parent in a child. By using this method, you do not trigger the parent's click event.

I think we also need to give the fpm container the volume, dont we? So =>

fpm:
    image: php:fpm
    volumes:
        - ./:/var/www/test/

If i dont do this, i run into this exception when firing a request, as fpm cannot find requested file:

[error] 6#6: *4 FastCGI sent in stderr: "Primary script unknown" while reading response header from upstream, client: 172.17.42.1, server: localhost, request: "GET / HTTP/1.1", upstream: "fastcgi://172.17.0.81:9000", host: "localhost"

I wrote this code snippet and it works fine:

<a href="#" class="clickable">Blah</a>
<input id="textbox">
<script type="text/javascript">
    $(document).ready(function(){
        $("a.clickable").click(function(event){
            event.preventDefault();
            $("input#textbox").val($(this).html());
        });  
    });
</script>

Maybe you forgot to give a class name "clickable" to your links?

Caveats

Here are two worthy caveats from the comments.

Either you want user to be of type User | {} or Partial<User>, or you need to redefine the User type to allow an empty object. Right now, the compiler is correctly telling you that user is not a User. – jcalz

I don't think this should be considered a proper answer because it creates an inconsistent instance of the type, undermining the whole purpose of TypeScript. In this example, the property Username is left undefined, while the type annotation is saying it can't be undefined. – Ian Liu Rodrigues

Answer

One of the design goals of TypeScript is to "strike a balance between correctness and productivity." If it will be productive for you to do this, use Type Assertions to create empty objects for typed variables.

type User = {
    Username: string;
    Email: string;
}

const user01 = {} as User;
const user02 = <User>{};

user01.Email = "[email protected]";

Here is a working example for you.

The following has worked for me.

I had a lot of local changes and needed to discard those in the local copy and checkout the last stable version in SVN.

1. Check the status of all files, including the ignored files.

2. Grep all the lines to get the newly added and ignored files.

3. Replace those with //.

4. and rm -rf all the lines.

   svn status --no-ignore | grep '^[?I]' | sed "s/^[?I] //" | xargs -I{} rm -rf "{}"

const loop (fn, times) => {
  if (!times) { return }
  fn()
  loop(fn, times - 1)
}

loop(something, 3)

I believe because cases must be constant values, the switch statement does the equivelent of a goto, so based on the value of the variable it jumps to the right case, whereas in the if/then statement it must evaluate each expression.

[Javascript] After a bit of jiggery pokery, this worked for me:

 let dateEvents = (
            {
                'Count': 2,
                'Items': [
                    {
                        'LastPostedDateTime': {
                            "S": "10/16/2019 11:04:59"
                        }
                    },
                    {
                        'LastPostedDateTime': {
                            "S": "10/30/2019 21:41:39"
                        }
                    }
                ],
            }
        );
        console.log('dateEvents', dateEvents);

The problem I needed to solve was that I might have any number of events and they would all have the same name: LastPostedDateTime all that is different is the date and time.

In my code I use DATETIME DEFAULT CURRENT_TIMESTAMP as the type and constraint of the column.

In your case your table definition would be

create table notes (
  _id integer primary key autoincrement, 
  created_date date default CURRENT_DATE
)

1. Yes, it means that for example if you do UPDATE parent SET id = 20 WHERE id = 10 all children parent_id's of 10 will also be updated to 20

2. If you don't update the field the foreign key refers to, this setting is not needed

3. Can't think of any other use.

4. You can't do that as the foreign key constraint would fail.

As mentioned in the error, the official manual and the comments:

Replace

public function TSStatus($host, $queryPort)

with

public function __construct($host, $queryPort)

You might also try giving the full path to the binary you're trying to run. That solved my problem when trying to use ImageMagick.

SHOW OPEN TABLES to show each table status and its lock.

For named locks look Show all current locks from get_lock

private function getFormDataArray($form)
{
    $data = [];
    foreach ( $form as $key => $value) {
        $data[$key] = $value->getData();
    }
    return $data;
}

for me this worked:

import org.apache.http.client.utils.URIBuilder;

String encodedString = new URIBuilder()
  .setParameter("i", stringToEncode)
  .build()
  .getRawQuery() // output: i=encodedString
  .substring(2);

or with a different UriBuilder

import javax.ws.rs.core.UriBuilder;

String encodedString = UriBuilder.fromPath("")
  .queryParam("i", stringToEncode)
  .toString()   // output: ?i=encodedString
  .substring(3);

In my opinion using a standard library is a better idea rather than post processing manually. Also @Chris answer looked good, but it doesn't work for urls, like "http://a+b c.html"

Modern browsers do not currently implement JSONRequest (as far as I know) since it is only a draft right now. I have found someone who has implemented it as a library that you can include in your page: http://devpro.it/JSON/files/JSONRequest-js.html (please note that it has a few dependencies).

Otherwise, you might want to go with another JS library like jQuery or Mootools.

<td class="virtualTd" onclick="putThis(this)">my td value </td>

function putThis(control) { 
    alert(control.innerText);
}

In .NET Core 2.0 the user already exists as part of the underlying inherited controller. Just use the User as you would normally or pass across to any repository code.

[Authorize(AuthenticationSchemes = JwtBearerDefaults.AuthenticationScheme, Policy = "TENANT")]
[HttpGet("issue-type-selection"), Produces("application/json")]
public async Task<IActionResult> IssueTypeSelection()
{
    try
    {
        return new ObjectResult(await _item.IssueTypeSelection(User));
    }
    catch (ExceptionNotFound)
    {
        Response.StatusCode = (int)HttpStatusCode.BadRequest;
        return Json(new
        {
            error = "invalid_grant",
            error_description = "Item Not Found"
        });
    }
}

This is where it inherits it from

I implemented this simple solution that works for me (not yet on production environment):

function verificarNovaVersio() {
    var sVersio = localStorage['gcf_versio'+ location.pathname] || 'v00.0.0000';
    $.ajax({
        url: "./versio.txt"
        , dataType: 'text'
        , cache: false
        , contentType: false
        , processData: false
        , type: 'post'
     }).done(function(sVersioFitxer) {
        console.log('Versió App: '+ sVersioFitxer +', Versió Caché: '+ sVersio);
        if (sVersio < (sVersioFitxer || 'v00.0.0000')) {
            localStorage['gcf_versio'+ location.pathname] = sVersioFitxer;
            location.reload(true);
        }
    });
}

I've a little file located where the html are:

"versio.txt":

v00.5.0014

This function is called in all of my pages, so when loading it checks if the localStorage's version value is lower than the current version and does a

location.reload(true);

...to force reload from server instead from cache.

(obviously, instead of localStorage you can use cookies or other persistent client storage)

I opted for this solution for its simplicity, because only mantaining a single file "versio.txt" will force the full site to reload.

The queryString method is hard to implement and is also cached (if you change from v1.1 to a previous version will load from cache, then it means that the cache is not flushed, keeping all previous versions at cache).

I'm a little newbie and I'd apreciate your professional check & review to ensure my method is a good approach.

Hope it helps.

Problem

I was running into the same error message while calling a third party API from my ASP.NET Core MVC project.

Could not establish secure channel for SSL/TLS with authority '{base_url_of_WS}'.

Solution

It turned out that the third party API's server required TLS 1.2. To resolve this issue, I added the following line of code to my controller's constructor:

System.Net.ServicePointManager.SecurityProtocol = System.Net.SecurityProtocolType.Tls12;

To the radio buttons works correctly, you must to have grouped by his name. (Ex. name="type")

 <fieldset>
    <legend>Please select one of the following</legend>
    <input type="radio" name="type" id="track" value="track" /><label for="track">Track Submission</label><br />
    <input type="radio" name="type" id="event" value="event"  /><label for="event">Events and Artist booking</label><br />
    <input type="radio" name="type" id="message" value="message" /><label for="message">Message us</label><br />

It will returns the value of the radio button checked (Ex. track | event | message)

You can try something like below

$($.parseHTML(<<table html string variable here>>)).find("td:contains('<<some text to find>>')").first().prev().text();

There is one difference - you can't use String without using System; beforehand.

set myPATH="C:\Users\DEB\Downloads\10.1.1.0.4"
cd %myPATH%

• The single quotes do not indicate a string, they make it starts: 'C:\ instead of C:\ so

• %name% is the usual syntax for expanding a variable, the !name! syntax needs to be enabled using the command setlocal ENABLEDELAYEDEXPANSION first, or by running the command prompt with CMD /V:ON.

• Don't use PATH as your name, it is a system name that contains all the locations of executable programs. If you overwrite it, random bits of your script will stop working. If you intend to change it, you need to do set PATH=%PATH%;C:\Users\DEB\Downloads\10.1.1.0.4 to keep the current PATH content, and add something to the end.

For windows

;extension=php_mcrypt.dll to extension=php_mcrypt.dll 
 then restart your apache server

For Redhat

sudo yum install php55-mcrypt //if php5.5
sudo yum install php-mcrypt //if less than 5.4
sudo service httpd restart //if apache 2.4
sudo /etc/init.d/httpd restart //if apache 2.2 or less

For Ubuntu

sudo apt-get install php5-mcrypt
sudo service apache2 restart //if server not reloaded automatically 

Still not working?

sudo php5enmod mcrypt && sudo service apache2 restart

If you're interested in making .xlsx (Office 2007 and beyond) files, you're in luck. Office 2007+ uses OpenXML which for lack of a more apt description is XML files inside of a zip named .xlsx

Take an excel file (2007+) and rename it to .zip, you can open it up and take a look. If you're using .NET 3.5 you can use the System.IO.Packaging library to manipulate the relationships & zipfile itself, and linq to xml to play with the xml (or just DOM if you're more comfortable).

Otherwise id reccomend DotNetZip, a powerfull library for manipulation of zipfiles.

OpenXMLDeveloper has lots of resources about OpenXML and you can find more there.

If you want .xls (2003 and below) you're going to have to look into 3rd party libraries or perhaps learn the file format yourself to achieve this without excel installed.

Wes McKinney (pandas' author) in Python for Data Analysis provides the following recipe:

groups = dict(list(gb))

which returns a dictionary whose keys are your group labels and whose values are DataFrames, i.e.

groups['foo']

will yield what you are looking for:

     A         B   C
0  foo  1.624345   5
2  foo -0.528172  11
4  foo  0.865408  14

    Asset::add('style', 'template/style.css');
    Asset::add('style2', 'css/style.css');

});

and using blade template engine

The thread is old, but maybe someone is still interested. The shortest form I found is further improvement on the example from ?lex and bmargulies. The execution tag will look like:

<execution>
    <id>TheNameOfTheRelevantExecution</id>
    <phase/>
</execution>

2 points I want to highlight:

1. phase is set to nothing, which looks less hacky than 'none', though still a hack.
2. id must be the same as execution you want to override. If you don't specify id for execution, Maven will do it implicitly (in a way not expected intuitively by you).

After posting found it is already in stackoverflow: In a Maven multi-module project, how can I disable a plugin in one child?

WHERE is applied as a limitation on the set returned by SQL; it uses SQL's built-in set oeprations and indexes and therefore is the fastest way to filter result sets. Always use WHERE whenever possible.

HAVING is necessary for some aggregate filters. It filters the query AFTER sql has retrieved, assembled, and sorted the results. Therefore, it is much slower than WHERE and should be avoided except in those situations that require it.

SQL Server will let you get away with using HAVING even when WHERE would be much faster. Don't do it.

FYI

Using netbeans New Entity Classes from Database with a mysql *auto_increment* column, creates you an attribute with the following annotations:

@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
@Basic(optional = false)
@Column(name = "id")
@NotNull
private Integer id;

This was getting me the same an error saying the column must not be null, so i simply removed the @NotNull anotation leaving the attribute null, and it works!

Since Java 1.5, String.format() can be used to left/right pad a given string.

public static String padRight(String s, int n) {
     return String.format("%-" + n + "s", s);  
}

public static String padLeft(String s, int n) {
    return String.format("%" + n + "s", s);  
}

...

public static void main(String args[]) throws Exception {
 System.out.println(padRight("Howto", 20) + "*");
 System.out.println(padLeft("Howto", 20) + "*");
}

And the output is:

Howto               *
               Howto*

Wouldn't establishing a connection to the database do this for you? If the database isn't up you won't be able to establish a connection.

This is the simple answer I can give.

If you have empty rows, not NAs, you can do:

data[!apply(data == "", 1, all),]

To remove both (NAs and empty):

data <- data[!apply(is.na(data) | data == "", 1, all),]

When you use only integers in a division, you will get integer division. When you use (at least one) double or float, you will get floating point division (and the answer you want to get).

So you can

1. declare one or both of the variables as float/double
2. cast one or both of the variables to float/double.

Do not just cast the result of the integer division to double: the division was already performed as integer division, so the numbers behind the decimal are already lost.

Another simple version working on PC:

Sub CreateDir(strPath As String)
    Dim elm As Variant
    Dim strCheckPath As String

    strCheckPath = ""
    For Each elm In Split(strPath, "\")
        strCheckPath = strCheckPath & elm & "\"
        If Len(Dir(strCheckPath, vbDirectory)) = 0 Then MkDir strCheckPath
    Next
End Sub

JsonLint is good for validating and formatting JSON.

Two points come to mind:

1. Security (but as long as you generate the string to be evaluated yourself, this might be a non-issue)

2. Performance: until the code to be executed is unknown, it cannot be optimized. (about javascript and performance, certainly Steve Yegge's presentation)

Purpose of view is displaying model. You should use controller to redirect request before creating model and passing it to view. Use Controller.RedirectToAction method for this.

Click in the logcat window (on a log even). Followed by "Ctrl + A" (select all). Then either "Right click with the mouse" or "Ctrl +C" (copy). Then paste it anywhere you like using any editor you like. One could also delete the logcat output before the logs relevant to us appear (before we start testing our use case) to get only relevant logs in the logcat.

Above answer won't work if the Display class will not work then you can get the width and height by below method.

private static final int WIDTH_INDEX = 0;
private static final int HEIGHT_INDEX = 1;

    public static int[] getScreenSize(Context context) {
        int[] widthHeight = new int[2];
        widthHeight[WIDTH_INDEX] = 0;
        widthHeight[HEIGHT_INDEX] = 0;

        try {
            WindowManager windowManager = (WindowManager) context.getSystemService(Context.WINDOW_SERVICE);
            Display display = windowManager.getDefaultDisplay();

            Point size = new Point();
            display.getSize(size);
            widthHeight[WIDTH_INDEX] = size.x;
            widthHeight[HEIGHT_INDEX] = size.y;

            if (!isScreenSizeRetrieved(widthHeight))
            {
                DisplayMetrics metrics = new DisplayMetrics();
                display.getMetrics(metrics);
                widthHeight[0] = metrics.widthPixels;
                widthHeight[1] = metrics.heightPixels;
            }

            // Last defense. Use deprecated API that was introduced in lower than API 13
            if (!isScreenSizeRetrieved(widthHeight)) {
                widthHeight[0] = display.getWidth(); // deprecated
                widthHeight[1] = display.getHeight(); // deprecated
            }
        } catch (Exception e) {
            e.printStackTrace();
        }

        return widthHeight;
    }

    private static boolean isScreenSizeRetrieved(int[] widthHeight) {
        return widthHeight[WIDTH_INDEX] != 0 && widthHeight[HEIGHT_INDEX] != 0;
    }

Use Notepad to create a text document and copy/paste this:

rmdir /s/q "%temp%"
mkdir "%temp%"

Select Save As and file name:

delete_temp.bat

Save as type: All files and click the Save button.

It works on any kind of account (administrator or a standard user). Just run it!

I use a temporary variable in this example, but you can use any other! PS: For Windows OS only!

If you open the Event Log viewer before the event source is created, for example while installing a service, you'll get that error message. You don't need to restart the OS: you simply have to close and open the event viewer.

NOTE: I don't provide a custom messages file. The creation of the event source uses the default configuration, as shown on Matt's answer.

Finally,

hmemcpy answer was totally for me and thanks to other friends who answered.

I grab the HttpValueCollection using Reflector and wrote the following code

        var hebe = new HttpValueCollection();
        hebe.Add(HttpUtility.ParseQueryString(Request.Url.Query));

        if (!string.IsNullOrEmpty(hebe["Language"]))
            hebe.Remove("Language");

        Response.Redirect(Request.Url.AbsolutePath + "?" + hebe );

 try {
        String result = URLDecoder.decode(urlString, "UTF-8");
    } catch (UnsupportedEncodingException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

Using true/false as the value will have the field pre-filled if the model passed to the form has this attribute already filled:

= f.radio_button(:public?, true)
= f.label(:public?, "yes", value: true)
= f.radio_button(:public?, false)
= f.label(:public?, "no", value: false)

Output size of sha1 is 160 bits. Which is 160/8 == 20 chars (if you use 8-bit chars) or 160/16 = 10 (if you use 16-bit chars).

Another simple way:

ActiveSheet.Rows(ActiveSheet.UsedRange.Rows.Count+1).Select    
Selection.EntireRow.Delete

or simpler:

ActiveSheet.Rows(ActiveSheet.UsedRange.Rows.Count+1).EntireRow.Delete

Use the "Edit top 200" option, then click on "Show SQL panel", modify your query with your WHERE clause, and execute the query. You'll be able to edit the results.

My team moved away from Bower and migrated to npm because:

• Programmatic usage was painful
• Bower's interface kept changing
• Some features, like the url shorthand, are entirely broken
• Using both Bower and npm in the same project is painful
• Keeping bower.json version field in sync with git tags is painful
• Source control != package management
• CommonJS support is not straightforward

For more details, see "Why my team uses npm instead of bower".

I noticed the same thing about BOTHER not being defined. Like Jamey Sharp said, you can find it in <asm/termios.h>. Just a forewarning, I think I ran into problems including both it and the regular <termios.h> file at the same time.

Aside from that, I found with the glibc I have, it still didn't work because glibc's tcsetattr was doing the ioctl for the old-style version of struct termios which doesn't pay attention to the speed setting. I was able to set a custom speed by manually doing an ioctl with the new style termios2 struct, which should also be available by including <asm/termios.h>:

struct termios2 tio;

ioctl(fd, TCGETS2, &tio);
tio.c_cflag &= ~CBAUD;
tio.c_cflag |= BOTHER;
tio.c_ispeed = 12345;
tio.c_ospeed = 12345;
ioctl(fd, TCSETS2, &tio);

My case was solved with SESSION_DOMAIN, in my local machine had to be set to xxx.localhost. It was causing conflicts with the production SESSION_DOMAIN, xxx.com that was set directly in the session.php config file.

Cross posting my answer from this SO question for another simple, pip version proof solution.

try:  # for pip >= 10
    from pip._internal.req import parse_requirements
    from pip._internal.download import PipSession
except ImportError:  # for pip <= 9.0.3
    from pip.req import parse_requirements
    from pip.download import PipSession

requirements = parse_requirements(os.path.join(os.path.dirname(__file__), 'requirements.txt'), session=PipSession())

if __name__ == '__main__':
    setup(
        ...
        install_requires=[str(requirement.req) for requirement in requirements],
        ...
    )

Then just throw in all your requirements under requirements.txt under project root directory.

var i2 = JsonConvert.DeserializeObject(obj["id"].ToString(), type);

throws a parsing exception due to missing quotes around the first argument (I think). I got it to work by adding the quotes:

var i2 = JsonConvert.DeserializeObject("\"" + obj["id"].ToString() + "\"", type);

I've been using Bitvise SSH Server and it's really great. From install to administration it does it all through a GUI so you won't be putting together a sshd_config file. Plus if you use their client, Tunnelier, you get some bonus features (like mapping shares, port forwarding setup up server side, etc.) If you don't use their client it will still work with the Open Source SSH clients.

It's not Open Source and it costs $39.95, but I think it's worth it.

UPDATE 2009-05-21 11:10: The pricing has changed. The current price is $99.95 per install for commercial, but now free for non-commercial/personal use. Here is the current pricing.

The NSDictionary and NSMutableDictionary docs are probably your best bet. They even have some great examples on how to do various things, like...

...create an NSDictionary

NSArray *keys = [NSArray arrayWithObjects:@"key1", @"key2", nil];
NSArray *objects = [NSArray arrayWithObjects:@"value1", @"value2", nil];
NSDictionary *dictionary = [NSDictionary dictionaryWithObjects:objects 
                                                       forKeys:keys];

...iterate over it

for (id key in dictionary) {
    NSLog(@"key: %@, value: %@", key, [dictionary objectForKey:key]);
}

...make it mutable

NSMutableDictionary *mutableDict = [dictionary mutableCopy];

Note: historic version before 2010: [[dictionary mutableCopy] autorelease]

...and alter it

[mutableDict setObject:@"value3" forKey:@"key3"];

...then store it to a file

[mutableDict writeToFile:@"path/to/file" atomically:YES];

...and read it back again

NSMutableDictionary *anotherDict = [NSMutableDictionary dictionaryWithContentsOfFile:@"path/to/file"];

...read a value

NSString *x = [anotherDict objectForKey:@"key1"];

...check if a key exists

if ( [anotherDict objectForKey:@"key999"] == nil ) NSLog(@"that key is not there");

...use scary futuristic syntax

From 2014 you can actually just type dict[@"key"] rather than [dict objectForKey:@"key"]

There is a new Android api that allows the user to select their phonenumber without the need for a permission. Take a look at: https://android-developers.googleblog.com/2017/10/effective-phone-number-verification.html

// Construct a request for phone numbers and show the picker
private void requestHint() {
    HintRequest hintRequest = new HintRequest.Builder()
       .setPhoneNumberIdentifierSupported(true)
       .build();

    PendingIntent intent = Auth.CredentialsApi.getHintPickerIntent(
        apiClient, hintRequest);
    startIntentSenderForResult(intent.getIntentSender(),
        RESOLVE_HINT, null, 0, 0, 0);
} 

Your format specifier is incorrect. From the printf() man page on my machine:

0 A zero '0' character indicating that zero-padding should be used rather than blank-padding. A '-' overrides a '0' if both are used;

Field Width: An optional digit string specifying a field width; if the output string has fewer characters than the field width it will be blank-padded on the left (or right, if the left-adjustment indicator has been given) to make up the field width (note that a leading zero is a flag, but an embedded zero is part of a field width);

Precision: An optional period, '.', followed by an optional digit string giving a precision which specifies the number of digits to appear after the decimal point, for e and f formats, or the maximum number of characters to be printed from a string; if the digit string is missing, the precision is treated as zero;

For your case, your format would be %09.3f:

#include <stdio.h>

int main(int argc, char **argv)
{
  printf("%09.3f\n", 4917.24);
  return 0;
}

Output:

$ make testapp
cc     testapp.c   -o testapp
$ ./testapp 
04917.240

Note that this answer is conditional on your embedded system having a printf() implementation that is standard-compliant for these details - many embedded environments do not have such an implementation.

I tried the following and it worked from my local file system.. Basically spark can read from local, HDFS and AWS S3 path

listrdd=sc.textFile("file:////home/cloudera/Downloads/master-data/retail_db/products")

According to MDN: Determining the dimensions of elements

offsetWidth and offsetHeight return the "total amount of space an element occupies, including the width of the visible content, scrollbars (if any), padding, and border"

clientWidth and clientHeight return "how much space the actual displayed content takes up, including padding but not including the border, margins, or scrollbars"

scrollWidth and scrollHeight return the "actual size of the content, regardless of how much of it is currently visible"

So it depends on whether the measured content is expected to be out of the current viewable area.

Microsoft recommends using singular for Enums unless the Enum represents bit fields (use the FlagsAttribute as well). See Enumeration Type Naming Conventions (a subset of Microsoft's Naming Guidelines).

To respond to your clarification, I see nothing wrong with either of the following:

public enum OrderStatus { Pending, Fulfilled, Error };

public class SomeClass { 
    public OrderStatus OrderStatus { get; set; }
}

or

public enum OrderStatus { Pending, Fulfilled, Error };

public class SomeClass {
    public OrderStatus Status { get; set; }
}

You can use the ID field as the equality identifier. You can't use the adhoc object for this case because AngularJS checks references equality when comparing objects.

<select 
    ng-model="Choice.SelectedOption.ID" 
    ng-options="choice.ID as choice.Name for choice in Choice.Options">
</select>

Problem is that while runtime generic type is erased so new E[10] would be equivalent to new Object[10].

This would be dangerous because it would be possible to put in array other data than of E type. That is why you need to explicitly say that type you want by either

• creating Object array and cast it to E[] array, or
• useing Array.newInstance(Class componentType, int length) to create real instance of array of type passed in componentType argiment.

Ok, sorry for the poor question. gbn got me on the right track. This is what I was looking for in an answer.

SELECT [FirstName], [MiddleName], [LastName], [Date] 
FROM #temp 
PIVOT
(   MIN([Data]) 
    FOR [DBColumnName] IN ([FirstName], [MiddleName], [LastName], [Date]) 
)AS p

Then I had to use a while statement and build the above statement as a varchar and use dynmaic sql.

Using something like this

SET @fullsql = @fullsql + 'SELECT ' + REPLACE(REPLACE(@fulltext,'(',''),')','')
SET @fullsql = @fullsql + 'FROM #temp '
SET @fullsql = @fullsql + 'PIVOT'
SET @fullsql = @fullsql + '('
SET @fullsql = @fullsql + ' MIN([Data])'
SET @fullsql = @fullsql + ' FOR [DBColumnName] IN '+@fulltext
SET @fullsql = @fullsql + ')'
SET @fullsql = @fullsql + 'AS p'

EXEC (@fullsql)

Having a to build @fulltext using a while loop and select the distinct column names out of the table. Thanks for the answers.

If you are using @Configuation then instantiate below static bean. If not static @Configutation is instantiated very early and and the BeanPostProcessors responsible for resolving annotations like @Value, @Autowired etc, cannot act on it. Refer here

@Bean
public static PropertySourcesPlaceholderConfigurer propertyConfigurer() {
   return new PropertySourcesPlaceholderConfigurer();
}

The code starts file search from root colon, If I want to start search from a specific directory, to avoid going to that directory every time, where I should put one. I did it like

Sub GetFilePath()
FileSelected = "G:\Audits\A2010"
Set myFile = Application.FileDialog(msoFileDialogOpen)
With myFile
.Title = "Choose File"
.AllowMultiSelect = False
If .Show <> -1 Then
Exit Sub
End If
FileSelected = .SelectedItems(1)

But it could not start reach from "G:\Audits\A2010"

Another way without JavaScript is to use <form autocomplete="off"> to prevent the browser from re-filling the form with the last values.

Tested this only with a single <input type="text"> inside the form, but works fine in current Chrome and Firefox, unfortunately not in IE10.

I have dealt WCF with large file (serveral GB) upload where store data in memory is not an option. My solution is to store message stream to a temp file and use seek to find out begin and end of binary data.

If you have a class file at build/com/foo/Hello.class, you can check what java version it is compiled at using the command:

javap -v build/com/foo/Hello.class | grep "major"

Example usage:

$ javap -v build/classes/java/main/org/aguibert/liberty/Book.class | grep major
  major version: 57

According to the table in the OP, major version 57 means the class file was compiled to JDK 13 bytecode level

I had this issue while testing software. Drivers were not signed.

Tip for me was: in cmd line: (administrator) bcdedit /set TESTSIGNING ON and reboot the machine (shutdown -r -t 5)

Note that setTimeout and setInterval are very different functions:

• setTimeout will execute the code once, after the timeout.
• setInterval will execute the code forever, in intervals of the provided timeout.

Both functions return a timer ID which you can use to abort the timeout. All you have to do is store that value in a variable and use it as argument to clearTimeout(tid) or clearInterval(tid) respectively.

So, depending on what you want to do, you have two valid choices:

// set timeout
var tid = setTimeout(mycode, 2000);
function mycode() {
  // do some stuff...
  tid = setTimeout(mycode, 2000); // repeat myself
}
function abortTimer() { // to be called when you want to stop the timer
  clearTimeout(tid);
}

or

// set interval
var tid = setInterval(mycode, 2000);
function mycode() {
  // do some stuff...
  // no need to recall the function (it's an interval, it'll loop forever)
}
function abortTimer() { // to be called when you want to stop the timer
  clearInterval(tid);
}

Both are very common ways of achieving the same.

Preliminary notes

• Although there's a clear differentiation between file and directory terms in the question text, some may argue that directories are actually special files
• The statement: "all files of a directory" can be interpreted in two ways:
  1. All direct (or level 1) descendants only
  2. All descendants in the whole directory tree (including the ones in sub-directories)

• When the question was asked, I imagine that Python 2, was the LTS version, however the code samples will be run by Python 3(.5) (I'll keep them as Python 2 compliant as possible; also, any code belonging to Python that I'm going to post, is from v3.5.4 - unless otherwise specified). That has consequences related to another keyword in the question: "add them into a list":

  • In pre Python 2.2 versions, sequences (iterables) were mostly represented by lists (tuples, sets, ...)
  • In Python 2.2, the concept of generator ([Python.Wiki]: Generators) - courtesy of [Python 3]: The yield statement) - was introduced. As time passed, generator counterparts started to appear for functions that returned/worked with lists
  • In Python 3, generator is the default behavior
  • Not sure if returning a list is still mandatory (or a generator would do as well), but passing a generator to the list constructor, will create a list out of it (and also consume it). The example below illustrates the differences on [Python 3]: map(function, iterable, ...)

  >>> import sys
  >>> sys.version
  '2.7.10 (default, Mar  8 2016, 15:02:46) [MSC v.1600 64 bit (AMD64)]'
  >>> m = map(lambda x: x, [1, 2, 3])  # Just a dummy lambda function
  >>> m, type(m)
  ([1, 2, 3], <type 'list'>)
  >>> len(m)
  3
  

  
  

  >>> import sys
  >>> sys.version
  '3.5.4 (v3.5.4:3f56838, Aug  8 2017, 02:17:05) [MSC v.1900 64 bit (AMD64)]'
  >>> m = map(lambda x: x, [1, 2, 3])
  >>> m, type(m)
  (<map object at 0x000001B4257342B0>, <class 'map'>)
  >>> len(m)
  Traceback (most recent call last):
    File "<stdin>", line 1, in <module>
  TypeError: object of type 'map' has no len()
  >>> lm0 = list(m)  # Build a list from the generator
  >>> lm0, type(lm0)
  ([1, 2, 3], <class 'list'>)
  >>>
  >>> lm1 = list(m)  # Build a list from the same generator
  >>> lm1, type(lm1)  # Empty list now - generator already consumed
  ([], <class 'list'>)
  

• The examples will be based on a directory called root_dir with the following structure (this example is for Win, but I'm using the same tree on Lnx as well):

  E:\Work\Dev\StackOverflow\q003207219>tree /f "root_dir"

Solutions

Programmatic approaches:

1. [Python 3]: os.listdir(path='.')

   Return a list containing the names of the entries in the directory given by path. The list is in arbitrary order, and does not include the special entries '.' and '..' ...

   
   

   >>> import os
   >>> root_dir = "root_dir"  # Path relative to current dir (os.getcwd())
   >>>
   >>> os.listdir(root_dir)  # List all the items in root_dir
   ['dir0', 'dir1', 'dir2', 'dir3', 'file0', 'file1']
   >>>
   >>> [item for item in os.listdir(root_dir) if os.path.isfile(os.path.join(root_dir, item))]  # Filter items and only keep files (strip out directories)
   ['file0', 'file1']
   

   A more elaborate example (code_os_listdir.py):

   import os
   from pprint import pformat
   
   
   def _get_dir_content(path, include_folders, recursive):
       entries = os.listdir(path)
       for entry in entries:
           entry_with_path = os.path.join(path, entry)
           if os.path.isdir(entry_with_path):
               if include_folders:
                   yield entry_with_path
               if recursive:
                   for sub_entry in _get_dir_content(entry_with_path, include_folders, recursive):
                       yield sub_entry
           else:
               yield entry_with_path
   
   
   def get_dir_content(path, include_folders=True, recursive=True, prepend_folder_name=True):
       path_len = len(path) + len(os.path.sep)
       for item in _get_dir_content(path, include_folders, recursive):
           yield item if prepend_folder_name else item[path_len:]
   
   
   def _get_dir_content_old(path, include_folders, recursive):
       entries = os.listdir(path)
       ret = list()
       for entry in entries:
           entry_with_path = os.path.join(path, entry)
           if os.path.isdir(entry_with_path):
               if include_folders:
                   ret.append(entry_with_path)
               if recursive:
                   ret.extend(_get_dir_content_old(entry_with_path, include_folders, recursive))
           else:
               ret.append(entry_with_path)
       return ret
   
   
   def get_dir_content_old(path, include_folders=True, recursive=True, prepend_folder_name=True):
       path_len = len(path) + len(os.path.sep)
       return [item if prepend_folder_name else item[path_len:] for item in _get_dir_content_old(path, include_folders, recursive)]
   
   
   def main():
       root_dir = "root_dir"
       ret0 = get_dir_content(root_dir, include_folders=True, recursive=True, prepend_folder_name=True)
       lret0 = list(ret0)
       print(ret0, len(lret0), pformat(lret0))
       ret1 = get_dir_content_old(root_dir, include_folders=False, recursive=True, prepend_folder_name=False)
       print(len(ret1), pformat(ret1))
   
   
   if __name__ == "__main__":
       main()
   

   Notes:

   • There are two implementations:
     • One that uses generators (of course here it seems useless, since I immediately convert the result to a list)
     • The classic one (function names ending in _old)
   • Recursion is used (to get into subdirectories)
   • For each implementation there are two functions:
     • One that starts with an underscore (_): "private" (should not be called directly) - that does all the work
     • The public one (wrapper over previous): it just strips off the initial path (if required) from the returned entries. It's an ugly implementation, but it's the only idea that I could come with at this point
   • In terms of performance, generators are generally a little bit faster (considering both creation and iteration times), but I didn't test them in recursive functions, and also I am iterating inside the function over inner generators - don't know how performance friendly is that
   • Play with the arguments to get different results

2. [Python 3]: os.scandir(path='.') (Python 3.5+, backport: [PyPI]: scandir)

   Return an iterator of os.DirEntry objects corresponding to the entries in the directory given by path. The entries are yielded in arbitrary order, and the special entries '.' and '..' are not included.

   Using scandir() instead of listdir() can significantly increase the performance of code that also needs file type or file attribute information, because os.DirEntry objects expose this information if the operating system provides it when scanning a directory. All os.DirEntry methods may perform a system call, but is_dir() and is_file() usually only require a system call for symbolic links; os.DirEntry.stat() always requires a system call on Unix but only requires one for symbolic links on Windows.

   
   

   >>> import os
   >>> root_dir = os.path.join(".", "root_dir")  # Explicitly prepending current directory
   >>> root_dir
   '.\\root_dir'
   >>>
   >>> scandir_iterator = os.scandir(root_dir)
   >>> scandir_iterator
   <nt.ScandirIterator object at 0x00000268CF4BC140>
   >>> [item.path for item in scandir_iterator]
   ['.\\root_dir\\dir0', '.\\root_dir\\dir1', '.\\root_dir\\dir2', '.\\root_dir\\dir3', '.\\root_dir\\file0', '.\\root_dir\\file1']
   >>>
   >>> [item.path for item in scandir_iterator]  # Will yield an empty list as it was consumed by previous iteration (automatically performed by the list comprehension)
   []
   >>>
   >>> scandir_iterator = os.scandir(root_dir)  # Reinitialize the generator
   >>> for item in scandir_iterator :
   ...     if os.path.isfile(item.path):
   ...             print(item.name)
   ...
   file0
   file1
   

   Notes:

   • It's similar to os.listdir
   • But it's also more flexible (and offers more functionality), more Pythonic (and in some cases, faster)

3. [Python 3]: os.walk(top, topdown=True, onerror=None, followlinks=False)

   Generate the file names in a directory tree by walking the tree either top-down or bottom-up. For each directory in the tree rooted at directory top (including top itself), it yields a 3-tuple (dirpath, dirnames, filenames).

   
   

   >>> import os
   >>> root_dir = os.path.join(os.getcwd(), "root_dir")  # Specify the full path
   >>> root_dir
   'E:\\Work\\Dev\\StackOverflow\\q003207219\\root_dir'
   >>>
   >>> walk_generator = os.walk(root_dir)
   >>> root_dir_entry = next(walk_generator)  # First entry corresponds to the root dir (passed as an argument)
   >>> root_dir_entry
   ('E:\\Work\\Dev\\StackOverflow\\q003207219\\root_dir', ['dir0', 'dir1', 'dir2', 'dir3'], ['file0', 'file1'])
   >>>
   >>> root_dir_entry[1] + root_dir_entry[2]  # Display dirs and files (direct descendants) in a single list
   ['dir0', 'dir1', 'dir2', 'dir3', 'file0', 'file1']
   >>>
   >>> [os.path.join(root_dir_entry[0], item) for item in root_dir_entry[1] + root_dir_entry[2]]  # Display all the entries in the previous list by their full path
   ['E:\\Work\\Dev\\StackOverflow\\q003207219\\root_dir\\dir0', 'E:\\Work\\Dev\\StackOverflow\\q003207219\\root_dir\\dir1', 'E:\\Work\\Dev\\StackOverflow\\q003207219\\root_dir\\dir2', 'E:\\Work\\Dev\\StackOverflow\\q003207219\\root_dir\\dir3', 'E:\\Work\\Dev\\StackOverflow\\q003207219\\root_dir\\file0', 'E:\\Work\\Dev\\StackOverflow\\q003207219\\root_dir\\file1']
   >>>
   >>> for entry in walk_generator:  # Display the rest of the elements (corresponding to every subdir)
   ...     print(entry)
   ...
   ('E:\\Work\\Dev\\StackOverflow\\q003207219\\root_dir\\dir0', ['dir00', 'dir01', 'dir02'], [])
   ('E:\\Work\\Dev\\StackOverflow\\q003207219\\root_dir\\dir0\\dir00', ['dir000'], ['file000'])
   ('E:\\Work\\Dev\\StackOverflow\\q003207219\\root_dir\\dir0\\dir00\\dir000', [], ['file0000'])
   ('E:\\Work\\Dev\\StackOverflow\\q003207219\\root_dir\\dir0\\dir01', [], ['file010', 'file011'])
   ('E:\\Work\\Dev\\StackOverflow\\q003207219\\root_dir\\dir0\\dir02', ['dir020'], [])
   ('E:\\Work\\Dev\\StackOverflow\\q003207219\\root_dir\\dir0\\dir02\\dir020', ['dir0200'], [])
   ('E:\\Work\\Dev\\StackOverflow\\q003207219\\root_dir\\dir0\\dir02\\dir020\\dir0200', [], [])
   ('E:\\Work\\Dev\\StackOverflow\\q003207219\\root_dir\\dir1', [], ['file10', 'file11', 'file12'])
   ('E:\\Work\\Dev\\StackOverflow\\q003207219\\root_dir\\dir2', ['dir20'], ['file20'])
   ('E:\\Work\\Dev\\StackOverflow\\q003207219\\root_dir\\dir2\\dir20', [], ['file200'])
   ('E:\\Work\\Dev\\StackOverflow\\q003207219\\root_dir\\dir3', [], [])
   

   Notes:

   • Under the scenes, it uses os.scandir (os.listdir on older versions)
   • It does the heavy lifting by recurring in subfolders

4. [Python 3]: glob.glob(pathname, *, recursive=False) ([Python 3]: glob.iglob(pathname, *, recursive=False))

   Return a possibly-empty list of path names that match pathname, which must be a string containing a path specification. pathname can be either absolute (like /usr/src/Python-1.5/Makefile) or relative (like ../../Tools/*/*.gif), and can contain shell-style wildcards. Broken symlinks are included in the results (as in the shell).
   ...
   Changed in version 3.5: Support for recursive globs using “**”.

   
   

   >>> import glob, os
   >>> wildcard_pattern = "*"
   >>> root_dir = os.path.join("root_dir", wildcard_pattern)  # Match every file/dir name
   >>> root_dir
   'root_dir\\*'
   >>>
   >>> glob_list = glob.glob(root_dir)
   >>> glob_list
   ['root_dir\\dir0', 'root_dir\\dir1', 'root_dir\\dir2', 'root_dir\\dir3', 'root_dir\\file0', 'root_dir\\file1']
   >>>
   >>> [item.replace("root_dir" + os.path.sep, "") for item in glob_list]  # Strip the dir name and the path separator from begining
   ['dir0', 'dir1', 'dir2', 'dir3', 'file0', 'file1']
   >>>
   >>> for entry in glob.iglob(root_dir + "*", recursive=True):
   ...     print(entry)
   ...
   root_dir\
   root_dir\dir0
   root_dir\dir0\dir00
   root_dir\dir0\dir00\dir000
   root_dir\dir0\dir00\dir000\file0000
   root_dir\dir0\dir00\file000
   root_dir\dir0\dir01
   root_dir\dir0\dir01\file010
   root_dir\dir0\dir01\file011
   root_dir\dir0\dir02
   root_dir\dir0\dir02\dir020
   root_dir\dir0\dir02\dir020\dir0200
   root_dir\dir1
   root_dir\dir1\file10
   root_dir\dir1\file11
   root_dir\dir1\file12
   root_dir\dir2
   root_dir\dir2\dir20
   root_dir\dir2\dir20\file200
   root_dir\dir2\file20
   root_dir\dir3
   root_dir\file0
   root_dir\file1
   

   Notes:

   • Uses os.listdir
   • For large trees (especially if recursive is on), iglob is preferred
   • Allows advanced filtering based on name (due to the wildcard)

5. [Python 3]: class pathlib.Path(*pathsegments) (Python 3.4+, backport: [PyPI]: pathlib2)

   >>> import pathlib
   >>> root_dir = "root_dir"
   >>> root_dir_instance = pathlib.Path(root_dir)
   >>> root_dir_instance
   WindowsPath('root_dir')
   >>> root_dir_instance.name
   'root_dir'
   >>> root_dir_instance.is_dir()
   True
   >>>
   >>> [item.name for item in root_dir_instance.glob("*")]  # Wildcard searching for all direct descendants
   ['dir0', 'dir1', 'dir2', 'dir3', 'file0', 'file1']
   >>>
   >>> [os.path.join(item.parent.name, item.name) for item in root_dir_instance.glob("*") if not item.is_dir()]  # Display paths (including parent) for files only
   ['root_dir\\file0', 'root_dir\\file1']
   

   Notes:

   • This is one way of achieving our goal
   • It's the OOP style of handling paths
   • Offers lots of functionalities

6. [Python 2]: dircache.listdir(path) (Python 2 only)

   • But, according to [GitHub]: python/cpython - (2.7) cpython/Lib/dircache.py, it's just a (thin) wrapper over os.listdir with caching

   
   

   def listdir(path):
       """List directory contents, using cache."""
       try:
           cached_mtime, list = cache[path]
           del cache[path]
       except KeyError:
           cached_mtime, list = -1, []
       mtime = os.stat(path).st_mtime
       if mtime != cached_mtime:
           list = os.listdir(path)
           list.sort()
       cache[path] = mtime, list
       return list
   

7. [man7]: OPENDIR(3) / [man7]: READDIR(3) / [man7]: CLOSEDIR(3) via [Python 3]: ctypes - A foreign function library for Python (POSIX specific)

           dirent_addr = readdir(dir_stream)

       root_dir = "root_dir"

       print(entries)

   Notes:

   • It loads the three functions from libc (loaded in the current process) and calls them (for more details check [SO]: How do I check whether a file exists without exceptions? (@CristiFati's answer) - last notes from item #4.). That would place this approach very close to the Python / C edge
   • LinuxDirent64 is the ctypes representation of struct dirent64 from [man7]: dirent.h(0P) (so are the DT_ constants) from my machine: Ubtu 16 x64 (4.10.0-40-generic and libc6-dev:amd64). On other flavors/versions, the struct definition might differ, and if so, the ctypes alias should be updated, otherwise it will yield Undefined Behavior
   • It returns data in the os.walk's format. I didn't bother to make it recursive, but starting from the existing code, that would be a fairly trivial task
   • Everything is doable on Win as well, the data (libraries, functions, structs, constants, ...) differ

8. [ActiveState.Docs]: win32file.FindFilesW (Win specific)

   Retrieves a list of matching filenames, using the Windows Unicode API. An interface to the API FindFirstFileW/FindNextFileW/Find close functions.

   
   

   >>> import os, win32file, win32con
   >>> root_dir = "root_dir"

   ['root_dir\\file0', 'root_dir\\file1']
   

   Notes:

   • win32file.FindFilesW is part of [GitHub]: mhammond/pywin32 - Python for Windows (pywin32) Extensions, which is a Python wrapper over WINAPIs
   • The documentation link is from ActiveState, as I didn't find any PyWin32 official documentation

9. Install some (other) third-party package that does the trick
   • Most likely, will rely on one (or more) of the above (maybe with slight customizations)

Notes:

• Code is meant to be portable (except places that target a specific area - which are marked) or cross:

  • platform (Nix, Win, )
  • Python version (2, 3, )

• Multiple path styles (absolute, relatives) were used across the above variants, to illustrate the fact that the "tools" used are flexible in this direction

• os.listdir and os.scandir use opendir / readdir / closedir ([MS.Docs]: FindFirstFileW function / [MS.Docs]: FindNextFileW function / [MS.Docs]: FindClose function) (via [GitHub]: python/cpython - (master) cpython/Modules/posixmodule.c)

• win32file.FindFilesW uses those (Win specific) functions as well (via [GitHub]: mhammond/pywin32 - (master) pywin32/win32/src/win32file.i)

• _get_dir_content (from point #1.) can be implemented using any of these approaches (some will require more work and some less)

  • Some advanced filtering (instead of just file vs. dir) could be done: e.g. the include_folders argument could be replaced by another one (e.g. filter_func) which would be a function that takes a path as an argument: filter_func=lambda x: True (this doesn't strip out anything) and inside _get_dir_content something like: if not filter_func(entry_with_path): continue (if the function fails for one entry, it will be skipped), but the more complex the code becomes, the longer it will take to execute

• Nota bene! Since recursion is used, I must mention that I did some tests on my laptop (Win 10 x64), totally unrelated to this problem, and when the recursion level was reaching values somewhere in the (990 .. 1000) range (recursionlimit - 1000 (default)), I got StackOverflow :). If the directory tree exceeds that limit (I am not an FS expert, so I don't know if that is even possible), that could be a problem.
  I must also mention that I didn't try to increase recursionlimit because I have no experience in the area (how much can I increase it before having to also increase the stack at OS level), but in theory there will always be the possibility for failure, if the dir depth is larger than the highest possible recursionlimit (on that machine)

• The code samples are for demonstrative purposes only. That means that I didn't take into account error handling (I don't think there's any try / except / else / finally block), so the code is not robust (the reason is: to keep it as simple and short as possible). For production, error handling should be added as well

Other approaches:

1. Use Python only as a wrapper

   • Everything is done using another technology
   • That technology is invoked from Python

   • The most famous flavor that I know is what I call the system administrator approach:

     • Use Python (or any programming language for that matter) in order to execute shell commands (and parse their outputs)
     • Some consider this a neat hack
     • I consider it more like a lame workaround (gainarie), as the action per se is performed from shell (cmd in this case), and thus doesn't have anything to do with Python.
     • Filtering (grep / findstr) or output formatting could be done on both sides, but I'm not going to insist on it. Also, I deliberately used os.system instead of subprocess.Popen.

     (py35x64_test) E:\Work\Dev\StackOverflow\q003207219>"e:\Work\Dev\VEnvs\py35x64_test\Scripts\python.exe" -c "import os;os.system(\"dir /b root_dir\")"
     dir0
     dir1
     dir2
     dir3
     file0
     file1
     

   In general this approach is to be avoided, since if some command output format slightly differs between OS versions/flavors, the parsing code should be adapted as well; not to mention differences between locales).

In addition to all the answers about how to find unpartitioned space, you may also have space allocated to an LVM volume but not actually in use. You can list physical volumes with the pvdisplay and see which volume groups each physical volume is associated with. If a physical volume isn't associated with any volume group, it's safe to reallocate or destroy. Assuming that it it is associated with a volume group, the next step is to use vgdisplay to show your those. Among other things, this will show if you have any free "physical extents" — blocks of storage you can assign to a logical volume. You can get this in a concise form with vgs:

$ sudo vgs
  VG     #PV #LV #SN Attr   VSize   VFree
  fedora   1   3   0 wz--n- 237.46g    0 

... and here you can see I have nothing free. If I did, that last number would be bigger than zero.

This is important, because that free space is invisible to du, df, and the like, and also will show up as an allocated partition if you are using fdisk or another partitioning tool.

function getURLParameter(name) {
  return decodeURIComponent((new RegExp('[?|&]' + name + '=' + '([^&;]+?)(&|#|;|$)').exec(location.search) || [null, ''])[1].replace(/\+/g, '%20')) || null;
}

So you can use:

myvar = getURLParameter('myvar');

This worked for me when I got the same error message...

JavaScript only has a Number type that stores floating point values.

There is no int.

Edit:

If you want to format the number as a string with two digits after the decimal point use:

(4).toFixed(2)

\p{L} matches a single code point in the category "letter".
\p{N} matches any kind of numeric character in any script.

I ran into this problem today after they switched our anti-virus software to Kaspersky.
In my case, the platform is Windows 7. My workspace is stored on mapped network drive. The strange thing is that, even though this appears to be a permission issue, I could manipulate files and folders at the same level as the inaccessible file without incident. So far, the only two workarounds are to move the workspace to the local drive or to uninstall Kaspersky. Removing and re-installing Kaspersky without the firewall feature did not do the trick.

I will update this answer if and when we find a more accommodating solution, though I expect that will involve adjusting the anti-virus software, not Eclipse.

SWIFT 4.x

The Strings in double quotes always confuse me, so I think answer to this question needs some graphical presentation to clear this out.

For a banking app, I have a LoginViewController and a BalanceViewController. Each have their respective screens.

The app starts and shows the Login screen. When login is successful, app opens the Balance screen.

Here is how it looks:

The login success is handled like this:

let storyBoard: UIStoryboard = UIStoryboard(name: "Balance", bundle: nil)
let balanceViewController = storyBoard.instantiateViewController(withIdentifier: "balance") as! BalanceViewController
self.present(balanceViewController, animated: true, completion: nil)

As you can see, the storyboard ID 'balance' in small letters is what goes in the second line of the code, and this is the ID which is defined in the storyboard settings, as in the attached screenshot.

The term 'Balance' with capital 'B' is the name of the storyboard file, which is used in the first line of the code.

We know that using hard coded Strings in code is a very bad practice, but somehow in iOS development it has become a common practice, and Xcode doesn't even warn about them.

when in pyspark multiple conditions can be built using &(for and) and | (for or).

Note:In pyspark t is important to enclose every expressions within parenthesis () that combine to form the condition

%pyspark
dataDF = spark.createDataFrame([(66, "a", "4"), 
                                (67, "a", "0"), 
                                (70, "b", "4"), 
                                (71, "d", "4")],
                                ("id", "code", "amt"))
dataDF.withColumn("new_column",
       when((col("code") == "a") | (col("code") == "d"), "A")
      .when((col("code") == "b") & (col("amt") == "4"), "B")
      .otherwise("A1")).show()

In Spark Scala code (&&) or (||) conditions can be used within when function

//scala
val dataDF = Seq(
      (66, "a", "4"), (67, "a", "0"), (70, "b", "4"), (71, "d", "4"
      )).toDF("id", "code", "amt")
dataDF.withColumn("new_column",
       when(col("code") === "a" || col("code") === "d", "A")
      .when(col("code") === "b" && col("amt") === "4", "B")
      .otherwise("A1")).show()

=======================

Output:
+---+----+---+----------+
| id|code|amt|new_column|
+---+----+---+----------+
| 66|   a|  4|         A|
| 67|   a|  0|         A|

sudo mysql -h127.0.0.1 -P3306 -uroot -e"UPDATE mysql.user SET password = PASSWORD('yourpassword') WHERE user = 'root'"

Well, there are lots of exceptions to throw, but here is how you throw an exception:

throw new IllegalArgumentException("INVALID");

Also, yes, you can create your own custom exceptions.

A note about exceptions. When you throw an exception (like above) and you catch the exception: the String that you supply in the exception can be accessed throw the getMessage() method.

try{
    methodThatThrowsException();
}catch(IllegalArgumentException e)
{
  e.getMessage();
}

You can register another directive on top of ng-click which amends the default behaviour of ng-click and stops the event propagation. This way you wouldn't have to add $event.stopPropagation by hand.

app.directive('ngClick', function() {
    return {
        restrict: 'A',
        compile: function($element, attr) {
            return function(scope, element, attr) {
                element.on('click', function(event) {
                    event.stopPropagation();
                });
            };
        }
    }
});

I prefer to do some filtering, based on @memmons's answer

In Objective-C:

// in the private class extension
@property (nonatomic, assign) CGFloat lastContentOffset;

// in the class implementation
- (void)scrollViewDidScroll:(UIScrollView *)scrollView {

    if (fabs(self.lastContentOffset - scrollView.contentOffset.x) > 20 ) {
        self.lastContentOffset = scrollView.contentOffset.x;
    }

    if (self.lastContentOffset > scrollView.contentOffset.x) {
        //  Scroll Direction Left
        //  do what you need to with scrollDirection here.
    } else {
        //  omitted 
        //  if (self.lastContentOffset < scrollView.contentOffset.x)

        //  do what you need to with scrollDirection here.
        //  Scroll Direction Right
    } 
}

When tested in - (void)scrollViewDidScroll:(UIScrollView *)scrollView:

NSLog(@"lastContentOffset: --- %f,   scrollView.contentOffset.x : --- %f", self.lastContentOffset, scrollView.contentOffset.x);

self.lastContentOffset changes very fast, the value gap is nearly 0.5f.

It is not necessary.

And occasionally, when handled in accurate condition, your orientation maybe get lost. (implementation statements skipped sometimes)

such as :

- (void)scrollViewDidScroll:(UIScrollView *)scrollView{

    CGFloat viewWidth = scrollView.frame.size.width;

    self.lastContentOffset = scrollView.contentOffset.x;
    // Bad example , needs value filtering

    NSInteger page = scrollView.contentOffset.x / viewWidth;

    if (page == self.images.count + 1 && self.lastContentOffset < scrollView.contentOffset.x ){
          //  Scroll Direction Right
          //  do what you need to with scrollDirection here.
    }
   ....

In Swift 4:

var lastContentOffset: CGFloat = 0

func scrollViewDidScroll(_ scrollView: UIScrollView) {

     if (abs(lastContentOffset - scrollView.contentOffset.x) > 20 ) {
         lastContentOffset = scrollView.contentOffset.x;
     }

     if (lastContentOffset > scrollView.contentOffset.x) {
          //  Scroll Direction Left
          //  do what you need to with scrollDirection here.
     } else {
         //  omitted
         //  if (self.lastContentOffset < scrollView.contentOffset.x)

         //  do what you need to with scrollDirection here.
         //  Scroll Direction Right
    }
}

You don't necessarily need to force a re-render.

This might not help OP, but in my case I only needed to update the width and height attributes on my canvas (which you can't do with CSS).

It looks like this:

import React from 'react';
import styled from 'styled-components';
import {throttle} from 'lodash';

class Canvas extends React.Component {

    componentDidMount() {
        window.addEventListener('resize', this.resize);
        this.resize();
    }

    componentWillUnmount() {
        window.removeEventListener('resize', this.resize);
    }

    resize = throttle(() => {
        this.canvas.width = this.canvas.parentNode.clientWidth;
        this.canvas.height = this.canvas.parentNode.clientHeight;
    },50)

    setRef = node => {
        this.canvas = node;
    }

    render() {
        return <canvas className={this.props.className} ref={this.setRef} />;
    }
}

export default styled(Canvas)`
   cursor: crosshair;
`

Use assign:

assign(paste("orca", i, sep = ""), list_name[[i]])

So this option has been renamed in version 2.1 (18 October 2015)

From the changelog:

 Mouse-mode has been rewritten.  There's now no longer options for:
    - mouse-resize-pane
    - mouse-select-pane
    - mouse-select-window
    - mode-mouse

  Instead there is just one option:  'mouse' which turns on mouse support

So this is what I'm using now in my .tmux.conf file

set -g mouse on

I found a faster way of embedding:

• Just copy the link.
• Paste the link and remove the "?s=19" part and add "/video/1"
• That's it.

Unique ID with count information

import java.util.concurrent.atomic.AtomicLong;

public class RandomIdUtils {

    private static AtomicLong atomicCounter = new AtomicLong();

    public static String createId() {

        String currentCounter = String.valueOf(atomicCounter.getAndIncrement());
        String uniqueId = UUID.randomUUID().toString();

        return uniqueId + "-" + currentCounter;
    }
}

the following works for me,

  mockMvc.perform(
            MockMvcRequestBuilders.post("/api/test/url")
                    .contentType(MediaType.APPLICATION_JSON)
                    .content(asJsonString(createItemForm)))
            .andExpect(status().isCreated());

  public static String asJsonString(final Object obj) {
    try {
        return new ObjectMapper().writeValueAsString(obj);
    } catch (Exception e) {
        throw new RuntimeException(e);
    }
}

from y import * 

• Say you have a file x and y.
• You want to import y file to x.

then go to your x file and place the above command. To test this just put a print function in your y file and when your import was successful then in x file it should print it.

You can't access element like you did (document.frm_new_user_request). You have to use the function getElementById:

document.getElementById("frm_new_user_request")

So getting a value from an input could look like this:

var value = document.getElementById("frm_new_user_request").value

Also you can use some JavaScript framework, e.g. jQuery, which simplifies operations with DOM (Document Object Model) and also hides differences between various browsers from you.

Getting a value from an input using jQuery would look like this:

• input with ID "element": var value = $("#element).value
• input with class "element": var value = $(".element).value

Are you looking for a particular extension? In your phpinfo();, just hit Ctrl+F in your web browser, type in the first 3-4 letters of the extension you're looking for, and it should show you whether or not its loaded.

Usually in phpinfo() it doesn't show you all the loaded extensions in one location, it has got a separate section for each loaded extension where it shows all of its variables, file paths, etc, so if there is no section for your extension name it probably means it isn't loaded.

Alternatively you can open your php.ini file and use the Ctrl+F method to find your extension, and see if its been commented out (usually by a semicolon near the start of the line).

Using AddDays(-1) worked for me until I tried to cross months. When I tried to subtract 2 days from 2017-01-01 the result was 2016-00-30. It could not handle the month change correctly (though the year seemed to be fine).

I used date = Convert.ToDateTime(date).Subtract(TimeSpan.FromDays(2)).ToString("yyyy-mm-dd"); and have no issues.

The latest version of core-js lib provides the polyfills from a different path. so use the following in the polyfills.js. And also change the target value to es5 in the tsconfig.base.json

What we do, is to create two tables for each multilingual object.

E.g. the first table contains only language-neutral data (primary key, etc.) and the second table contains one record per language, containing the localized data plus the ISO code of the language.

In some cases we add a DefaultLanguage field, so that we can fall-back to that language if no localized data is available for a specified language.

Example:

Table "Product":
----------------
ID                 : int
<any other language-neutral fields>


Table "ProductTranslations"
---------------------------
ID                 : int      (foreign key referencing the Product)
Language           : varchar  (e.g. "en-US", "de-CH")
IsDefault          : bit
ProductDescription : nvarchar
<any other localized data>

With this approach, you can handle as many languages as needed (without having to add additional fields for each new language).

Update (2014-12-14): please have a look at this answer, for some additional information about the implementation used to load multilingual data into an application.

Use re.findall or re.finditer instead.

re.findall(pattern, string) returns a list of matching strings.

re.finditer(pattern, string) returns an iterator over MatchObject objects.

Example:

re.findall( r'all (.*?) are', 'all cats are smarter than dogs, all dogs are dumber than cats')
# Output: ['cats', 'dogs']

[x.group() for x in re.finditer( r'all (.*?) are', 'all cats are smarter than dogs, all dogs are dumber than cats')]
# Output: ['all cats are', 'all dogs are']

If you are eager to know how to use an OR condition in a Ruby switch case:

So, in a case statement, a , is the equivalent of || in an if statement.

case car
   when 'Maruti', 'Hyundai'
      # Code here
end

See "How A Ruby Case Statement Works And What You Can Do With It".

The table normally contains multiple rows. Use a loop and use row.Field<string>(0) to access the value of each row.

foreach(DataRow row in dt.Rows)
{
    string file = row.Field<string>("File");
}

You can also access it via index:

foreach(DataRow row in dt.Rows)
{
    string file = row.Field<string>(0);
}

If you expect only one row, you can also use the indexer of DataRowCollection:

string file = dt.Rows[0].Field<string>(0); 

Since this fails if the table is empty, use dt.Rows.Count to check if there is a row:

if(dt.Rows.Count > 0)
    file = dt.Rows[0].Field<string>(0);

this simple script worked for me.

<?php

foreach($_FILES as $file){
  //echo $file['name']; 
  echo $file['tmp_name'].'</br>'; 
  move_uploaded_file($file['tmp_name'], "./uploads/".$file["name"]);
}

?>

Best way I came across doing is like this:

HTML5:

<p>Initial Colors <a id="new-color">Different Colors</a></p>

CSS3:

p {
    color: #000000;
    text-decoration-line: underline;
    text-decoration-color: #a11015;
}

p #new-color{
    color: #a11015;
    text-decoration-line: underline;
    text-decoration-color: #000000;
}

Updated: My first answer was premature and contained a bug.

I expanded just slightly on the isValidDate function Thorbin posted above (using a regex). We use a regex to check the format (to prevent us from getting another format which would be valid for Date). After this loose check we then actually run it through the Date constructor and return true or false if it is valid within this format. If it is not a valid date we will get false from this function.

function isValidDate(dateString) {_x000D_
  var regEx = /^\d{4}-\d{2}-\d{2}$/;_x000D_
  if(!dateString.match(regEx)) return false;  // Invalid format_x000D_
  var d = new Date(dateString);_x000D_
  var dNum = d.getTime();_x000D_
  if(!dNum && dNum !== 0) return false; // NaN value, Invalid date_x000D_
  return d.toISOString().slice(0,10) === dateString;_x000D_
}_x000D_
_x000D_
_x000D_
/* Example Uses */_x000D_
console.log(isValidDate("0000-00-00"));  // false_x000D_
console.log(isValidDate("2015-01-40"));  // false_x000D_
console.log(isValidDate("2016-11-25"));  // true_x000D_
console.log(isValidDate("1970-01-01"));  // true = epoch_x000D_
console.log(isValidDate("2016-02-29"));  // true = leap day_x000D_
console.log(isValidDate("2013-02-29"));  // false = not leap day

An ioctl, which means "input-output control" is a kind of device-specific system call. There are only a few system calls in Linux (300-400), which are not enough to express all the unique functions devices may have. So a driver can define an ioctl which allows a userspace application to send it orders. However, ioctls are not very flexible and tend to get a bit cluttered (dozens of "magic numbers" which just work... or not), and can also be insecure, as you pass a buffer into the kernel - bad handling can break things easily.

An alternative is the sysfs interface, where you set up a file under /sys/ and read/write that to get information from and to the driver. An example of how to set this up:

static ssize_t mydrvr_version_show(struct device *dev,
        struct device_attribute *attr, char *buf)
{
    return sprintf(buf, "%s\n", DRIVER_RELEASE);
}

static DEVICE_ATTR(version, S_IRUGO, mydrvr_version_show, NULL);

And during driver setup:

device_create_file(dev, &dev_attr_version);

You would then have a file for your device in /sys/, for example, /sys/block/myblk/version for a block driver.

Another method for heavier use is netlink, which is an IPC (inter-process communication) method to talk to your driver over a BSD socket interface. This is used, for example, by the WiFi drivers. You then communicate with it from userspace using the libnl or libnl3 libraries.

the simpleset solution

look at my selector

$myForm.find('#fieldsetUserInfo input:disabled').prop("disabled", false);

the fieldsetUserInfo is div contains all inputs I want to disabled or Enable

hope this helps you

Files named __init__.py are used to mark directories on disk as Python package directories. If you have the files

mydir/spam/__init__.py
mydir/spam/module.py

and mydir is on your path, you can import the code in module.py as

import spam.module

or

from spam import module

If you remove the __init__.py file, Python will no longer look for submodules inside that directory, so attempts to import the module will fail.

The __init__.py file is usually empty, but can be used to export selected portions of the package under more convenient name, hold convenience functions, etc. Given the example above, the contents of the init module can be accessed as

import spam

based on this

For each works with JQuery as in

$(<selector>).each(function() {
   //this points to item
   alert('<msg>');
});

JQuery also, for a popup, has in the UI library a dialog widget: http://jqueryui.com/demos/dialog/

Check it out, works really well.

HTH.

Strangely, no one answered the bottom part of the question for years even though this is an important one -- data.frames are simply lists with the right attributes, so if you have large data you don't want to use as.data.frame or similar for a list. It's much faster to simply "turn" a list into a data frame in-place:

attr(df, "row.names") <- .set_row_names(length(df[[1]]))
class(df) <- "data.frame"

This makes no copy of the data so it's immediate (unlike all other methods). It assumes that you have already set names() on the list accordingly.

[As for loading large data into R -- personally, I dump them by column into binary files and use readBin() - that is by far the fastest method (other than mmapping) and is only limited by the disk speed. Parsing ASCII files is inherently slow (even in C) compared to binary data.]

What are you expecting? The default Tomcat homepage? If so, you'll need to configure Eclipse to take control over from Tomcat.

Doubleclick the Tomcat server entry in the Servers tab, you'll get the server configuration. At the left column, under Server Locations, select Use Tomcat installation (note, when it is grayed out, read the section leading text! ;) ). This way Eclipse will take full control over Tomcat, this way you'll also be able to access the default Tomcat homepage with the Tomcat Manager when running from inside Eclipse. I only don't see how that's useful while developing using Eclipse.

The port number is not the problem. You would otherwise have gotten an exception in Tomcat's startup log and the browser would show a browser-specific "Connection timed out" error page (and thus not a Tomcat-specific error page which would impossibly be served when Tomcat was not up and running!)

Eclipse for PHP Developers Package

Looking for the Eclipse for PHP Developers Package?

Due to lack of a package maintainer for the Indigo release there will be no PHP (PDT) package. If you would like to install PDT into your Eclipse installtion you can do so by using the Install New Software feature from the Help Menu and installing the PHP Development Tools (PDT) SDK Feature from the Eclipse Indigo Repo >> http://download.eclipse.org/releases/indigo

log4j2 has a very flexible configuration system (which IMHO is more a distraction than a help), you can even use JSON. See https://logging.apache.org/log4j/2.x/manual/configuration.html for a reference.

Personally, I just recently started using log4j2, but I'm tending toward the "strict XML" configuration (that is, using attributes instead of element names), which can be schema-validated.

Here is my simple example using autoconfiguration and strict mode, using a "Property" for setting the filename:

<?xml version="1.0" encoding="UTF-8"?>
<Configuration monitorinterval="30" status="info" strict="true">
    <Properties>
        <Property name="filename">log/CelsiusConverter.log</Property>
    </Properties>
    <Appenders>
        <Appender type="Console" name="Console">
            <Layout type="PatternLayout" pattern="%d %p [%t] %m%n" />
        </Appender>
        <Appender type="Console" name="FLOW">
            <Layout type="PatternLayout" pattern="%C{1}.%M %m %ex%n" />
        </Appender>
        <Appender type="File" name="File" fileName="${filename}">
            <Layout type="PatternLayout" pattern="%d %p %C{1.} [%t] %m%n" />
        </Appender>
    </Appenders>
    <Loggers>
        <Root level="debug">
            <AppenderRef ref="File" />
            <AppenderRef ref="Console" />
            <!-- Use FLOW to trace down exact method sending the msg -->
            <!-- <AppenderRef ref="FLOW" /> -->
        </Root>
    </Loggers>
</Configuration>

For portability, one should probably use std::signal from the standard C++ library, but there is a lot of restriction on what a signal handler can do. Unfortunately, it is not possible to catch a SIGSEGV from within a C++ program without introducing undefined behavior because the specification says:

1. it is undefined behavior to call any library function from within the handler other than a very narrow subset of the standard library functions (abort, exit, some atomic functions, reinstall current signal handler, memcpy, memmove, type traits, `std::move, std::forward, and some more).
2. it is undefined behavior if handler use a throw expression.
3. it is undefined behavior if the handler returns when handling SIGFPE, SIGILL, SIGSEGV

This proves that it is impossible to catch SIGSEGV from within a program using strictly standard and portable C++. SIGSEGV is still caught by the operating system and is normally reported to the parent process when a wait family function is called.

You will probably run into the same kind of trouble using POSIX signal because there is a clause that says in 2.4.3 Signal Actions:

The behavior of a process is undefined after it returns normally from a signal-catching function for a SIGBUS, SIGFPE, SIGILL, or SIGSEGV signal that was not generated by kill(), sigqueue(), or raise().

A word about the longjumps. Assuming we are using POSIX signals, using longjump to simulate stack unwinding won't help:

Although longjmp() is an async-signal-safe function, if it is invoked from a signal handler which interrupted a non-async-signal-safe function or equivalent (such as the processing equivalent to exit() performed after a return from the initial call to main()), the behavior of any subsequent call to a non-async-signal-safe function or equivalent is undefined.

This means that the continuation invoked by the call to longjump cannot reliably call usually useful library function such as printf, malloc or exit or return from main without inducing undefined behavior. As such, the continuation can only do a restricted operations and may only exit through some abnormal termination mechanism.

To put things short, catching a SIGSEGV and resuming execution of the program in a portable is probably infeasible without introducing UB. Even if you are working on a Windows platform for which you have access to Structured exception handling, it is worth mentioning that MSDN suggest to never attempt to handle hardware exceptions: Hardware Exceptions.

At last but not least, whether any SIGSEGV would be raised when dereferencing a null valued pointer (or invalid valued pointer) is not a requirement from the standard. Because indirection through a null valued pointer or any invalid valued pointer is an undefined behaviour, which means the compiler assumes your code will never attempt such a thing at runtime, the compiler is free to make code transformation that would elide such undefined behavior. For example, from cppreference,

int foo(int* p) {
    int x = *p;
    if(!p)
        return x; // Either UB above or this branch is never taken
    else
        return 0;
}
 
int main() {
    int* p = nullptr;
    std::cout << foo(p);
}

Here the true path of the if could be completely elided by the compiler as an optimization; only the else part could be kept. Said otherwise, the compiler infers foo() will never receive a null valued pointer at runtime since it would lead to an undefined behaviour. Invoking it with a null valued pointer, you may observe the value 0 printed to standard output and no crash, you may observe a crash with SIGSEG, in fact you could observe anything since no sensible requirements are imposed on programs that are not free of undefined behaviors.
