If you're ok with using a third party library, check out traex/RippleEffect. It allows you to add a Ripple effect to ANY view with just a few lines of code. You just need to wrap, in your xml layout file, the element you want to have a ripple effect with a com.andexert.library.RippleView container.

As an added bonus it requires Min SDK 9 so you can have design consistency across OS versions.

Here's an example taken from the libraries' GitHub repo:

<com.andexert.library.RippleView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    app:rv_centered="true">

    <ImageView
        android:layout_width="100dp"
        android:layout_height="100dp"
        android:src="@android:drawable/ic_menu_edit"
        android:background="@android:color/holo_blue_dark"/> 

</com.andexert.library.RippleView>

You can change the ripple colour by adding this attribute the the RippleView element: app:rv_color="@color/my_fancy_ripple_color

$('input[name=myradiobutton]:radio:checked') will get you the selected radio button $('input[name=myradiobutton]:radio:not(:checked)') will get you the unselected radio buttons

Using this you can do this

$('input[name=myradiobutton]:radio:not(:checked)').val("0");

Update: After reading your Update I think I understand You will want to do something like this

var myRadioValue;

function radioValue(jqRadioButton){
  if (jqRadioButton.length) {
    myRadioValue = jqRadioButton.val();
  }
  else {
    myRadioValue = 0;
  }
}

$(document).ready(function () {
  $('input[name=myradiobutton]:radio').click(function () {   //Hook the click event for selected elements
    radioValue($('input[name=myradiobutton]:radio:checked'));
  });

  radioValue($('input[name=myradiobutton]:radio:checked')); //check for value on page load
});

http://www.scala-lang.org/docu/files/api/scala/Enumeration.html

Example use

  object Main extends App {

    object WeekDay extends Enumeration {
      type WeekDay = Value
      val Mon, Tue, Wed, Thu, Fri, Sat, Sun = Value
    }
    import WeekDay._

    def isWorkingDay(d: WeekDay) = ! (d == Sat || d == Sun)

    WeekDay.values filter isWorkingDay foreach println
  }

As explained in the section 9 of the official ECMA specification (http://www.ecma-international.org/publications/files/ECMA-ST/ECMA-404.pdf) in JSON, the following chars have to be escaped:

• U+0022 (", the quotation mark)
• U+005C (\, the backslash or reverse solidus)
• U+0000 to U+001F (the ASCII control characters)

In addition, in order to safely embed JSON in HTML, the following chars have to be also escaped:

• U+002F (/)
• U+0027 (')
• U+003C (<)
• U+003E (>)
• U+0026 (&)
• U+0085 (Next Line)
• U+2028 (Line Separator)
• U+2029 (Paragraph Separator)

Some of the above characters can be escaped with the following short escape sequences defined in the standard:

• \" represents the quotation mark character (U+0022).
• \\ represents the reverse solidus character (U+005C).
• \/ represents the solidus character (U+002F).
• \b represents the backspace character (U+0008).
• \f represents the form feed character (U+000C).
• \n represents the line feed character (U+000A).
• \r represents the carriage return character (U+000D).
• \t represents the character tabulation character (U+0009).

The other characters which need to be escaped will use the \uXXXX notation, that is \u followed by the four hexadecimal digits that encode the code point.

The \uXXXX can be also used instead of the short escape sequence, or to optionally escape any other character from the Basic Multilingual Plane (BMP).

This should do it:

sed -e s/deletethis//g -i *
sed -e "s/deletethis//g" -i.backup *
sed -e "s/deletethis//g" -i .backup *

it will replace all occurrences of "deletethis" with "" (nothing) in all files (*), editing them in place.

In the second form the pattern can be edited a little safer, and it makes backups of any modified files, by suffixing them with ".backup".

The third form is the way some versions of sed like it. (e.g. Mac OS X)

man sed for more information.

I know several responses have suggested exporting the file to csv or some other text format, and then comparing them. I haven't seen it mentioned specifically, but Beyond Compare 3 has a number of additional file formats that it supports. See Additional File Formats. Using one of the Microsoft Excel File Formats you can easily compare two Excel files without going through the export to another format option.

Use int64_t, that portable C99 code.

int64_t var = 0x0000444400004444LL;

For printing:

#define __STDC_FORMAT_MACROS
#include <inttypes.h>

printf("blabla %" PRIi64 " blabla\n", var);

A bit surprised to see None of the above answers considers it can be multiple times faster using a thread pool. Here, parallel uses a fork-join thread pool and automatically break the stream in multiple parts and run them parallel and then merge. If you just remember the following line of code you can use it many places.

So the award for the fastest short and sweet code goes to -

int[] nums = {1,2,3};
int sum =  Arrays.stream(nums).parallel().reduce(0, (a,b)-> a+b);

Lets say you want to do sum of squares , then Arrays.stream(nums).parallel().map(x->x*x).reduce(0, (a,b)-> a+b). Idea is you can still perform reduce , without map .

Square brackets:

jsObj['key' + i] = 'example' + 1;

In JavaScript, all arrays are objects, but not all objects are arrays. The primary difference (and one that's pretty hard to mimic with straight JavaScript and plain objects) is that array instances maintain the length property so that it reflects one plus the numeric value of the property whose name is numeric and whose value, when converted to a number, is the largest of all such properties. That sounds really weird, but it just means that given an array instance, the properties with names like "0", "5", "207", and so on, are all treated specially in that their existence determines the value of length. And, on top of that, the value of length can be set to remove such properties. Setting the length of an array to 0 effectively removes all properties whose names look like whole numbers.

OK, so that's what makes an array special. All of that, however, has nothing at all to do with how the JavaScript [ ] operator works. That operator is an object property access mechanism which works on any object. It's important to note in that regard that numeric array property names are not special as far as simple property access goes. They're just strings that happen to look like numbers, but JavaScript object property names can be any sort of string you like.

Thus, the way the [ ] operator works in a for loop iterating through an array:

for (var i = 0; i < myArray.length; ++i) {
  var value = myArray[i]; // property access
  // ...
}

is really no different from the way [ ] works when accessing a property whose name is some computed string:

var value = jsObj["key" + i];

The [ ] operator there is doing precisely the same thing in both instances. The fact that in one case the object involved happens to be an array is unimportant, in other words.

When setting property values using [ ], the story is the same except for the special behavior around maintaining the length property. If you set a property with a numeric key on an array instance:

myArray[200] = 5;

then (assuming that "200" is the biggest numeric property name) the length property will be updated to 201 as a side-effect of the property assignment. If the same thing is done to a plain object, however:

myObj[200] = 5;

there's no such side-effect. The property called "200" of both the array and the object will be set to the value 5 in otherwise the exact same way.

One might think that because that length behavior is kind-of handy, you might as well make all objects instances of the Array constructor instead of plain objects. There's nothing directly wrong about that (though it can be confusing, especially for people familiar with some other languages, for some properties to be included in the length but not others). However, if you're working with JSON serialization (a fairly common thing), understand that array instances are serialized to JSON in a way that only involves the numerically-named properties. Other properties added to the array will never appear in the serialized JSON form. So for example:

var obj = [];
obj[0] = "hello world";
obj["something"] = 5000;

var objJSON = JSON.stringify(obj);

the value of "objJSON" will be a string containing just ["hello world"]; the "something" property will be lost.

ES2015:

If you're able to use ES6 JavaScript features, you can use Computed Property Names to handle this very easily:

var key = 'DYNAMIC_KEY',
    obj = {
        [key]: 'ES6!'
    };

console.log(obj);
// > { 'DYNAMIC_KEY': 'ES6!' }

Just wanted to add that if you want to add several parameters with the same key name for example: www.test.com/home?id=1&id=2

let params = new HttpParams();
params = params.append(key, value);

Use append, if you use set, it will overwrite the previous value with the same key name.

So I'm going to go a bit deeper in to why this doesn't work because I'm the kind of person that can't sleep at night without knowing haha. I'm using jQuery validate 1.10 and Microsoft jQuery Unobtrusive Validation 2.0.20710.0 which was published on 1/29/2013.

I started by searching for the setDefaults method in jQuery Validate and found it on line 261 of the unminified file. All this function really does is merge your json settings in to the existing $.validator.defaults which are initialized with the ignore property being set to ":hidden" along with the other defaults defined in jQuery Validate. So at this point we've overridden ignore. Now let's see where this defaults property is being referenced at.

When I traced through the code to see where $.validator.defaults is being referenced. I noticed that is was only being used by the constructor for a form validator, line 170 in jQuery validate unminified file.

// constructor for validator
$.validator = function( options, form ) {
    this.settings = $.extend( true, {}, $.validator.defaults, options );
    this.currentForm = form;
    this.init();
};

At this point a validator will merge any default settings that were set and attach it to the form validator. When you look at the code that is doing the validating, highlighting, unhighlighting, etc they all use the validator.settings object to pull the ignore property. So we need to make sure if we are to set the ignore with the setDefaults method then it has to occur before the $("form").validate() is called.

If you're using Asp.net MVC and the unobtrusive plugin, then you'll realize after looking at the javascript that validate is called in document.ready. I've also called my setDefaults in the document.ready block which is going to execute after the scripts, jquery validate and unobtrusive because I've defined those scripts in the html before the one that has the call in it. So my call obviously had no impact on the default functionality of skipping hidden elements during validation. There is a couple of options here.

Option 1 - You could as Juan Mellado pointed out have the call outside of the document.ready which would execute as soon as the script has been loaded. I'm not sure about the timing of this since browsers are now capable of doing parallel script loading. If I'm just being over cautious then please correct me. Also, there's probably ways around this but for my needs I did not go down this path.

Option 2a - The safe bet in my eyes is to just replace the $.validator.setDefaults({ ignore: '' }); inside of the document.ready event with $("form").data("validator").settings.ignore = "";. This will modify the ignore property that is actually used by jQuery validate when doing each validation on your elements for the given form.

Options 2b - After looking in to the code a bit more you could also use $("form").validate().settings.ignore = ""; as a way of setting the ignore property. The reason is that when looking at the validate function it checks to see if a validator object has already been stored for the form element via the $.data() function. If it finds a validator object stored with the form element then it just returns the validator object instead of creating another one.

<% ViewData.ModelState.IsValid %>

or

<% ViewData.ModelState.Values.Any(x => x.Errors.Count >= 1) %>

and for a specific property...

<% ViewData.ModelState["Property"].Errors %> // Note this returns a collection

This is a little late to the party, and a shameless plug for a package I wrote, but you can also check out the Columnar package.

It takes a list of lists of input and a list of headers and outputs a table-formatted string. This snippet creates a docker-esque table:

from columnar import columnar

headers = ['name', 'id', 'host', 'notes']

data = [
    ['busybox', 'c3c37d5d-38d2-409f-8d02-600fd9d51239', 'linuxnode-1-292735', 'Test server.'],
    ['alpine-python', '6bb77855-0fda-45a9-b553-e19e1a795f1e', 'linuxnode-2-249253', 'The one that runs python.'],
    ['redis', 'afb648ba-ac97-4fb2-8953-9a5b5f39663e', 'linuxnode-3-3416918', 'For queues and stuff.'],
    ['app-server', 'b866cd0f-bf80-40c7-84e3-c40891ec68f9', 'linuxnode-4-295918', 'A popular destination.'],
    ['nginx', '76fea0f0-aa53-4911-b7e4-fae28c2e469b', 'linuxnode-5-292735', 'Traffic Cop'],
]

table = columnar(data, headers, no_borders=True)
print(table)

Or you can get a little fancier with colors and borders.

All answers mentioned here are too old and lengthy.The best and short solution that work with latest Navigationview is

@Override
public void onDrawerSlide(View drawerView, float slideOffset) {
    super.onDrawerSlide(drawerView, slideOffset);

    try {
        //int currentapiVersion = android.os.Build.VERSION.SDK_INT;
        if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.LOLLIPOP){
            // Do something for lollipop and above versions

        Window window = getWindow();

        // clear FLAG_TRANSLUCENT_STATUS flag:
        window.clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);

        // add FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS flag to the window
        window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);

        // finally change the color to any color with transparency

         window.setStatusBarColor(getResources().getColor(R.color.colorPrimaryDarktrans));}

    } catch (Exception e) {

        Crashlytics.logException(e);

    }
}

this is going to change your status bar color to transparent when you open the drawer

Now when you close the drawer you need to change status bar color again to dark.So you can do it in this way.

        public void onDrawerClosed(View drawerView) {
        super.onDrawerClosed(drawerView);
        try {
    if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.LOLLIPOP){
    // Do something for lollipop and above versions

    Window window = getWindow();

    // clear FLAG_TRANSLUCENT_STATUS flag:
    window.clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);

    // add FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS flag to the window
    window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);

    // finally change the color again to dark
    window.setStatusBarColor(getResources().getColor(R.color.colorPrimaryDark));}
    } catch (Exception e) {
    Crashlytics.logException(e);
                    }
                    }

and then in main layout add a single line i.e

            android:fitsSystemWindows="true"

and your drawer layout will look like

            <android.support.v4.widget.DrawerLayout     
            xmlns:android="http://schemas.android.com/apk/res/android"
            xmlns:app="http://schemas.android.com/apk/res-auto"
            xmlns:tools="http://schemas.android.com/tools"
            android:id="@+id/drawer_layout"
            android:fitsSystemWindows="true"
            android:layout_width="match_parent"
            android:layout_height="match_parent">

and your navigation view will look like

    <android.support.design.widget.NavigationView
        android:id="@+id/navigation_view"
        android:layout_height="match_parent"
        android:layout_width="wrap_content"
        android:layout_gravity="start"
        android:fitsSystemWindows="true"
        app:headerLayout="@layout/navigation_header"
        app:menu="@menu/drawer"
        />

I have tested it and its fully working.Hope it helps someone.This may not be the best approach but it works smoothly and is simple to implement. Mark it up if it helps.Happy coding :)

First of all as the name suggests a view is immutable. thats because a view is nothing other than a virtual table created from a stored query in the DB. Because of this you have some characteristics of views:

• you can show only a subset of the data
• you can join multiple tables into a single view
• you can aggregate data in a view (select count)
• view dont actually hold data, they dont need any tablespace since they are virtual aggregations of underlying tables

so there are a gazillion of use cases for which views are better fitted than tables, just think about only displaying active users on a website. a view would be better because you operate only on a subset of the data which actually is in your DB (active and inactive users)

check out this article

hope this helped..

On Windows

if not exist "$(OBJDIR)" mkdir $(OBJDIR)

On Unix | Linux

if [ ! -d "$(OBJDIR)" ]; then mkdir $(OBJDIR); fi

Try this:

public class Person {
    public int Id { get; set; }
    public string Name { get; set; }
}

And then:

var list = new[] {   
    new Person { Id = 1, Name = "Name1" }, 
    new Person { Id = 2, Name = "Name2" }, 
    new Person { Id = 3, Name = "Name3" } 
};

var selectList = new SelectList(list, "Id", "Name", 2);
ViewData["People"] = selectList;

Html.DropDownList("PeopleClass", (SelectList)ViewData["People"])

With MVC RC2, I get:

<select id="PeopleClass" name="PeopleClass">
    <option value="1">Name1</option>
    <option selected="selected" value="2">Name2</option>
    <option value="3">Name3</option>
</select>

If you have the need to keep the environment variables in a script you can put your command in a here document like this. Especially if you have lots of variables to set things look tidy this way.

# prepare a script e.g. for running maven
runmaven=/tmp/runmaven$$
# create the script with a here document 
cat << EOF > $runmaven
#!/bin/bash
# run the maven clean with environment variables set
export ANT_HOME=/usr/share/ant
export MAKEFLAGS=-j4
mvn clean install
EOF
# make the script executable
chmod +x $runmaven
# run it
sudo $runmaven
# remove it or comment out to keep
rm $runmaven

work with you apply runat="server" in your div section...

<div runat="server" id="hideid">

On your button click event:

 protected void btnSubmit_Click(object sender, EventArgs e)
    {
      hideid.Visible = false;
    }

Just add "D".

int i = 6;
double d = i / 2D; // This will divide bei double.
System.out.println(d); // This will print a double. = 3D

This error arises when you don't use brackets with pop operation. Write the code in this manner.

listb.pop(0)

This is a valid python expression.

I had to do this and used subprocess.

import subprocess

subprocess.run("python3 script1.py & python3 script2.py", shell=True)

You could do it this way but it leaves it as a varchar

declare @s varchar(50)

set @s = '2011-09-28 18:01:00'

select convert(varchar, cast(@s as datetime), 105) + RIGHT(@s, 9)

or

select convert(varchar(20), @s, 105)

Taken from the MySQL 8.0 Reference Manual:

• utf8mb4: A UTF-8 encoding of the Unicode character set using one to four bytes per character.

• utf8mb3: A UTF-8 encoding of the Unicode character set using one to three bytes per character.

In MySQL utf8 is currently an alias for utf8mb3 which is deprecated and will be removed in a future MySQL release. At that point utf8 will become a reference to utf8mb4.

So regardless of this alias, you can consciously set yourself an utf8mb4 encoding.

To complete the answer, I'd like to add the @WilliamEntriken's comment below (also taken from the manual):

To avoid ambiguity about the meaning of utf8, consider specifying utf8mb4 explicitly for character set references instead of utf8.

Behavior is the most convenient way here.

• From one hand, it can be binded to the given viewmodel (that can signal "close the form!")

• From another hand, it has access to the form itself so can subscribe to necessary form-specific events, or show confirmation dialog, or anything else.

Writing necessary behavior can be seen boring very first time. However, from now on, you can reuse it on every single form you need by exact one-liner XAML snippet. And if necessary, you can extract it as a separate assembly so it can be included into any next project you want.

from subprocess import call

def cp_dir(source, target):
    call(['cp', '-a', source, target]) # Linux

cp_dir('/a/b/c/', '/x/y/z/')

It works for me. Basically, it executes shell command cp.

If you're chaining a view functions to the array e.g.

array.map(i => i+1).filter(i => i > 3)

And want the first element after these functions you can simply add a .shift() it doesn't modify the original array, its a nicer way then array.map(i => i+1).filter(=> i > 3)[0]

If you want the first element of an array without modifying the original you can use array[0] or array.map(n=>n).shift() (without the map you will modify the original. In this case btw i would suggest the ..[0] version.

       <TextView android:layout_width="match_parent"
                 android:layout_height="wrap_content"

                 android:focusable="true"
                 android:focusableInTouchMode="true">

                <requestFocus/>
      </TextView>

      <EditText android:layout_width="match_parent"
                android:layout_height="wrap_content"/>

So, eventually I did that thing that all developers hate doing. I went and checked the server log files and found a report of a syntax error in line n.

tail -n 20 /var/log/apache2/error.log

The easy way is to make a for where you verify if the atrrtibute name of the custom object have the desired string

    for(Datapoint d : dataPointList){
        if(d.getName() != null && d.getName().contains(search))
           //something here
    }

I think this helps you.

It should be this:

if (myString!="-1")
{
//Do things
}

Your equals and exclamation are the wrong way round.

matrix = [[1,2,3],
          [1,2,3],
          [1,2,3],
          [1,2,3],
          [1,2,3],
          [1,2,3],
          [1,2,3]]
    
rows = len(matrix)
cols = len(matrix[0])

transposed = []
while len(transposed) < cols:
    transposed.append([])
    while len(transposed[-1]) < rows:
        transposed[-1].append(0)

for i in range(rows):
    for j in range(cols):
        transposed[j][i] = matrix[i][j]

for i in transposed:
    print(i)

You might also encounter this error if you are not using origin keyword and the branch isn't one of your own.

git checkout <to-branch> 
git merge origin/<from-branch>

Based on your comment under @Raul's answer, I can think of two ways to include a callback:

1. Have getScript call the file that loads the css.
2. Load the contents of the css file with AJAX, and append to <style>. Your callback would be the callback from $.get or whatever you use to load the css file contents.

in case if your table has tbody

let tbl = document.getElementById("tbl").getElementsByTagName('tbody')[0];
console.log(tbl.rows[0].cells[0].innerHTML)

For python 3 it would be like this n,m,p=map(int,input().split())

And if you need to extract several properties from each object, then

let newArr = _.map(arr, o => _.pick(o, ['name', 'surname', 'rate']));

On this page, the Arduino sketch defines a couple of Structs (plus a couple of methods) which are then called in the setup loop and main loop. Simple enough to interpret, even for a barely-literate programmer like me.

We are working on a framework for strict REST services, check out http://prestans.googlecode.com

Its in early Alpha at the moment, we are testing against mod_wsgi and Google's AppEngine.

Looking for testers and feedback. Thanks.

If your web application is configured to impersonate a client, then using a trusted connection will potentially have a negative performance impact. This is because each client must use a different connection pool (with the client's credentials).

Most web applications don't use impersonation / delegation, and hence don't have this problem.

See this MSDN article for more information.

i also ran into this problem due to syntax error. Using "(" instead of "[" in array index:

   foreach($arr_parameters as $arr_key=>$arr_value) {
        $arr_named_parameters(":$arr_key") = $arr_value;
    }

isFakeGPSInstalled = Utils.isPackageInstalled(Utils.PACKAGE_ID_FAKE_GPS, this.getPackageManager());

    try {
      packageManager.getPackageInfo(packageName, 0);
    } catch (PackageManager.NameNotFoundException e) {
      found = false;
    }

    return found;
  }

One main difference is the Local part of LocalDateTime. If you live in Germany and create a LocalDateTime instance and someone else lives in USA and creates another instance at the very same moment (provided the clocks are properly set) - the value of those objects would actually be different. This does not apply to Instant, which is calculated independently from time zone.

LocalDateTime stores date and time without timezone, but it's initial value is timezone dependent. Instant's is not.

Moreover, LocalDateTime provides methods for manipulating date components like days, hours, months. An Instant does not.

apart from the nanosecond precision advantage of Instant and the time-zone part of LocalDateTime

Both classes have the same precision. LocalDateTime does not store timezone. Read javadocs thoroughly, because you may make a big mistake with such invalid assumptions: Instant and LocalDateTime.

Here is a few ways to do it (Just assume I'm using Dependency Injection for the DbConext)

public class Example
{
    private readonly DbContext Context;

    public Example(DbContext context)
    {
        Context = context;
    }

    public DbSetSampleOne[] DbSamples { get; set; }

    public void ExampleMethod DoSomething()
    {
        // Example 1: This will select everything from the entity you want to select
        DbSamples = Context.DbSetSampleOne.ToArray();

        // Example 2: If you want to apply some filtering use the following example
        DbSamples = Context.DbSetSampleOne.ToArray().Where(p => p.Field.Equals("some filter"))

    }

In general compact is preferable to repairDatabase. But one advantage of repair over compact is you can issue repair to the whole cluster. compact you have to log into each shard, which is kind of annoying.

Alternative

Use element .innerHTML= which is quite fast in modern browsers

document.body.innerHTML = "<canvas width=500 height=150 id='CursorLayer'>";


// TEST

var ctx = CursorLayer.getContext("2d");
ctx.fillStyle = "red";
ctx.fillRect(100, 100, 50, 50);

canvas { border: 1px solid black }

I solved this by writing the explicit IP address defined in the Listener.ora file as the hostname.



So, instead of "localhost", I wrote "192.168.1.2" as the "Hostname" in the SQL Developer field.

In the below picture I highlighted the input boxes that I've modified:

Looks like you created a separate question. I was answering your other question How to change flat file source using foreach loop container in an SSIS package? with the same answer. Anyway, here it is again.

Create two string data type variables namely DirPath and FilePath. Set the value C:\backup\ to the variable DirPath. Do not set any value to the variable FilePath.

Select the variable FilePath and select F4 to view the properties. Set the EvaluateAsExpression property to True and set the Expression property as @[User::DirPath] + "Source" + (DT_STR, 4, 1252) DATEPART("yy" , GETDATE()) + "-" + RIGHT("0" + (DT_STR, 2, 1252) DATEPART("mm" , GETDATE()), 2) + "-" + RIGHT("0" + (DT_STR, 2, 1252) DATEPART("dd" , GETDATE()), 2)

This worked like a charm for me, of-course it requires super-user privileges :-)

# hcitool cc <target-bdaddr>; hcitool auth <target-bdaddr>

To get <target-bdaddr> you may issue below command:
$ hcitool scan

Note: Exclude # & $ as they are command line prompts.

Here is another way without extra modules:

I needed to guess the environment from the task name, I have a 'dev' task and a 'prod' task.

When I run gulp prod it should be set to prod environment. When I run gulp dev or anything else it should be set to dev environment.

For that I just check the running task name:

devEnv = process.argv[process.argv.length-1] !== 'prod';

https://firebase.google.com/docs/auth/web/manage-users

You have to add an auth state change observer.

firebase.auth().onAuthStateChanged(function(user) {
  if (user) {
    // User is signed in.
  } else {
    // No user is signed in.
  }
});

For a quick and lazy solution, (and not using VS at all) try these online converters:

• xsd-to-xml-converter here
• xmltocsharp converter here

XSD => XML => C# classes

Example XSD:

<?xml version="1.0" encoding="UTF-8" ?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">

<xs:element name="shiporder">
  <xs:complexType>
    <xs:sequence>
      <xs:element name="orderperson" type="xs:string"/>
      <xs:element name="shipto">
        <xs:complexType>
          <xs:sequence>
            <xs:element name="name" type="xs:string"/>
            <xs:element name="address" type="xs:string"/>
            <xs:element name="city" type="xs:string"/>
            <xs:element name="country" type="xs:string"/>
          </xs:sequence>
        </xs:complexType>
      </xs:element>
      <xs:element name="item" maxOccurs="unbounded">
        <xs:complexType>
          <xs:sequence>
            <xs:element name="title" type="xs:string"/>
            <xs:element name="note" type="xs:string" minOccurs="0"/>
            <xs:element name="quantity" type="xs:positiveInteger"/>
            <xs:element name="price" type="xs:decimal"/>
          </xs:sequence>
        </xs:complexType>
      </xs:element>
    </xs:sequence>
    <xs:attribute name="orderid" type="xs:string" use="required"/>
  </xs:complexType>
</xs:element>

</xs:schema>

Converts to XML:

Attention! Take in account that this is just to Get-You-Started, the results obviously need refinements!

You cannot do so - the browser will not allow this because of security concerns.

When a file is selected by using the input type=file object, the value of the value property depends on the value of the "Include local directory path when uploading files to a server" security setting for the security zone used to display the Web page containing the input object.

The fully qualified filename of the selected file is returned only when this setting is enabled. When the setting is disabled, Internet Explorer 8 replaces the local drive and directory path with the string C:\fakepath\ in order to prevent inappropriate information disclosure.

And other

You missed ); this at the end of the change event function.

Also do not create function for change event instead just use it as below,

<script type="text/javascript">

    $(function()
    {
        $('#fileUpload').on('change',function ()
        {
            var filePath = $(this).val();
            console.log(filePath);
        });
    });

</script>

PHP is run server-side. JavaScript is run client-side in the browser of the user requesting the page. By the time the JavaScript is executed, there is no access to PHP on the server whatsoever. Please read this article with details about client-side vs server-side coding.

What happens in a nutshell is this:

• You click a link in your browser on your computer under your desk
• The browser creates an HTTP request and sends it to a server on the Internet
• The server checks if he can handle the request
• If the request is for a PHP page, the PHP interpreter is started
• The PHP interpreter will run all PHP code in the page you requested
• The PHP interpreter will NOT run any JS code, because it has no clue about it
• The server will send the page assembled by the interpreter back to your browser
• Your browser will render the page and show it to you
• JavaScript is executed on your computer

In your case, PHP will write the JS code into the page, so it can be executed when the page is rendered in your browser. By that time, the PHP part in your JS snippet does no longer exist. It was executed on the server already. It created a variable $result that contained a SQL query string. You didn't use it, so when the page is send back to your browser, it's gone. Have a look at the sourcecode when the page is rendered in your browser. You will see that there is nothing at the position you put the PHP code.

The only way to do what you are looking to do is either:

• do a redirect to a PHP script or
• do an AJAX call to a PHP script

with the values you want to be insert into the database.

stoi is a C++11 function. If you aren't using a compiler that understands C++11, this simply won't compile.

You can use a stringstream instead to read the input:

stringstream ss(hours0);
ss >> hours;

find the below explanation:

int main()
{
    int a = 10;// say address of 'a' is 2000;
    int *p = &a; //it means 'p' is pointing[referencing] to 'a'. i.e p->2000
    int c = *p; //*p means dereferncing. it will give the content of the address pointed by 'p'. in this case 'p' is pointing to 2000[address of 'a' variable], content of 2000 is 10. so *p will give 10. 
}

conclusion :

1. & [address operator] is used for referencing.
2. * [star operator] is used for de-referencing .

Write-Host "filesizecounter : " $filesizecounter 

alter table table_name add field_name (size);

alter table arnicsc add place number(10);

Edit:

Here is a viable replacement for jQuery ready

function ready(callback){
    // in case the document is already rendered
    if (document.readyState!='loading') callback();
    // modern browsers
    else if (document.addEventListener) document.addEventListener('DOMContentLoaded', callback);
    // IE <= 8
    else document.attachEvent('onreadystatechange', function(){
        if (document.readyState=='complete') callback();
    });
}

ready(function(){
    // do something
});

Taken from https://plainjs.com/javascript/events/running-code-when-the-document-is-ready-15/

Another good domReady function here taken from https://stackoverflow.com/a/9899701/175071

As the accepted answer was very far from complete, I stitched together a "ready" function like jQuery.ready() based on jQuery 1.6.2 source:

var ready = (function(){

    var readyList,
        DOMContentLoaded,
        class2type = {};
        class2type["[object Boolean]"] = "boolean";
        class2type["[object Number]"] = "number";
        class2type["[object String]"] = "string";
        class2type["[object Function]"] = "function";
        class2type["[object Array]"] = "array";
        class2type["[object Date]"] = "date";
        class2type["[object RegExp]"] = "regexp";
        class2type["[object Object]"] = "object";

    var ReadyObj = {
        // Is the DOM ready to be used? Set to true once it occurs.
        isReady: false,
        // A counter to track how many items to wait for before
        // the ready event fires. See #6781
        readyWait: 1,
        // Hold (or release) the ready event
        holdReady: function( hold ) {
            if ( hold ) {
                ReadyObj.readyWait++;
            } else {
                ReadyObj.ready( true );
            }
        },
        // Handle when the DOM is ready
        ready: function( wait ) {
            // Either a released hold or an DOMready/load event and not yet ready
            if ( (wait === true && !--ReadyObj.readyWait) || (wait !== true && !ReadyObj.isReady) ) {
                // Make sure body exists, at least, in case IE gets a little overzealous (ticket #5443).
                if ( !document.body ) {
                    return setTimeout( ReadyObj.ready, 1 );
                }

                // Remember that the DOM is ready
                ReadyObj.isReady = true;
                // If a normal DOM Ready event fired, decrement, and wait if need be
                if ( wait !== true && --ReadyObj.readyWait > 0 ) {
                    return;
                }
                // If there are functions bound, to execute
                readyList.resolveWith( document, [ ReadyObj ] );

                // Trigger any bound ready events
                //if ( ReadyObj.fn.trigger ) {
                //    ReadyObj( document ).trigger( "ready" ).unbind( "ready" );
                //}
            }
        },
        bindReady: function() {
            if ( readyList ) {
                return;
            }
            readyList = ReadyObj._Deferred();

            // Catch cases where $(document).ready() is called after the
            // browser event has already occurred.
            if ( document.readyState === "complete" ) {
                // Handle it asynchronously to allow scripts the opportunity to delay ready
                return setTimeout( ReadyObj.ready, 1 );
            }

            // Mozilla, Opera and webkit nightlies currently support this event
            if ( document.addEventListener ) {
                // Use the handy event callback
                document.addEventListener( "DOMContentLoaded", DOMContentLoaded, false );
                // A fallback to window.onload, that will always work
                window.addEventListener( "load", ReadyObj.ready, false );

            // If IE event model is used
            } else if ( document.attachEvent ) {
                // ensure firing before onload,
                // maybe late but safe also for iframes
                document.attachEvent( "onreadystatechange", DOMContentLoaded );

                // A fallback to window.onload, that will always work
                window.attachEvent( "onload", ReadyObj.ready );

                // If IE and not a frame

                var toplevel = false;

        DOMContentLoaded = function() {

        // Attach the listeners
        ReadyObj.bindReady();

        var type = ReadyObj.type( fn );

        // Add the callback
        readyList.done( fn );//readyList is result of _Deferred()
    }
    return ready;
})();

How to use:

<script>
    ready(function(){
        alert('It works!');
    });
    ready(function(){
        alert('Also works!');
    });
</script>

I am not sure how functional this code is, but it worked fine with my superficial tests. This took quite a while, so I hope you and others can benefit from it.

PS.: I suggest compiling it.

Or you can use http://dustindiaz.com/smallest-domready-ever:

function r(f){/in/.test(document.readyState)?setTimeout(r,9,f):f()}
r(function(){/*code to run*/});

or the native function if you only need to support the new browsers (Unlike jQuery ready, this won't run if you add this after the page has loaded)

document.addEventListener('DOMContentLoaded',function(){/*fun code to run*/})

editText.setTypeface(Typeface.createFromAsset(getAssets(), ttfFilePath));
etitText.setTypeface(et.getTypeface(), Typeface.BOLD);

will set both typface as well as style to Bold.

You can use the datapart to maintain time date type and you can compare it to another time.
Check below example:

declare @fromtime time = '09:30'
declare @totime time
SET @totime=CONVERT(TIME, CONCAT(DATEPART(HOUR, GETDATE()),':', DATEPART(MINUTE, GETDATE())))
if @fromtime <= @totime 
begin print 'true' end
else begin print 'no' end

You could as well get more easy-to-interpret picture of where tags point to using

git log --graph |git name-rev --stdin --tags |less

and then scroll to the tag you're looking for via /.

More compact view (--pretty=oneline) plus all heads (-a) could also help:

git log -a --pretty=oneline --graph |git name-rev --stdin --tags |less

Looks a bit terrifying, but could also be aliased in ~/.gitconfig if necessary.

~/.gitconfig

[alias]
ls-tags = !git log -a --pretty=oneline --graph |git name-rev --stdin --tags |less

Note in 2018: readAsBinaryString is outdated. For use cases where previously you'd have used it, these days you'd use readAsArrayBuffer (or in some cases, readAsDataURL) instead.

readAsBinaryString says that the data must be represented as a binary string, where:

...every byte is represented by an integer in the range [0..255].

JavaScript originally didn't have a "binary" type (until ECMAScript 5's WebGL support of Typed Array* (details below) -- it has been superseded by ECMAScript 2015's ArrayBuffer) and so they went with a String with the guarantee that no character stored in the String would be outside the range 0..255. (They could have gone with an array of Numbers instead, but they didn't; perhaps large Strings are more memory-efficient than large arrays of Numbers, since Numbers are floating-point.)

If you're reading a file that's mostly text in a western script (mostly English, for instance), then that string is going to look a lot like text. If you read a file with Unicode characters in it, you should notice a difference, since JavaScript strings are UTF-16** (details below) and so some characters will have values above 255, whereas a "binary string" according to the File API spec wouldn't have any values above 255 (you'd have two individual "characters" for the two bytes of the Unicode code point).

If you're reading a file that's not text at all (an image, perhaps), you'll probably still get a very similar result between readAsText and readAsBinaryString, but with readAsBinaryString you know that there won't be any attempt to interpret multi-byte sequences as characters. You don't know that if you use readAsText, because readAsText will use an encoding determination to try to figure out what the file's encoding is and then map it to JavaScript's UTF-16 strings.

You can see the effect if you create a file and store it in something other than ASCII or UTF-8. (In Windows you can do this via Notepad; the "Save As" as an encoding drop-down with "Unicode" on it, by which looking at the data they seem to mean UTF-16; I'm sure Mac OS and *nix editors have a similar feature.) Here's a page that dumps the result of reading a file both ways:

If I use that with a "Testing 1 2 3" file stored in UTF-16, here are the results I get:

Text (13):

54 65 73 74 69 6e 67 20 31 20 32 20 33

Binary (28):

ff fe 54 00 65 00 73 00 74 00 69 00 6e 00 67 00 20 00 31 00 20 00 32 00 20 00 33 00

As you can see, readAsText interpreted the characters and so I got 13 (the length of "Testing 1 2 3"), and readAsBinaryString didn't, and so I got 28 (the two-byte BOM plus two bytes for each character).

* XMLHttpRequest.response with responseType = "arraybuffer" is supported in HTML 5.

** "JavaScript strings are UTF-16" may seem like an odd statement; aren't they just Unicode? No, a JavaScript string is a series of UTF-16 code units; you see surrogate pairs as two individual JavaScript "characters" even though, in fact, the surrogate pair as a whole is just one character. See the link for details.

Short answers:

Q1: Yes.

Q2: Doesn't matter which you use.

Long answer:

A select ... for update will (as it implies) select certain rows but also lock them as if they have already been updated by the current transaction (or as if the identity update had been performed). This allows you to update them again in the current transaction and then commit, without another transaction being able to modify these rows in any way.

Another way of looking at it, it is as if the following two statements are executed atomically:

select * from my_table where my_condition;

update my_table set my_column = my_column where my_condition;

Since the rows affected by my_condition are locked, no other transaction can modify them in any way, and hence, transaction isolation level makes no difference here.

Note also that transaction isolation level is independent of locking: setting a different isolation level doesn't allow you to get around locking and update rows in a different transaction that are locked by your transaction.

What transaction isolation levels do guarantee (at different levels) is the consistency of data while transactions are in progress.

If you're on Linux, or have cygwin available on Windows, you can run the input XML through a simple sed script that will replace <Active>True</Active> with <Active>true</Active>, like so:

cat <your XML file> | sed 'sX<Active>True</Active>X<Active>true</Active>X' | xmllint --schema -

If you're not, you can still use a non-validating xslt pocessor (xalan, saxon etc.) to run a simple xslt transformation on the input, and only then pipe it to xmllint.

What the xsl should contain something like below, for the example you listed above (the xslt processor should be 2.0 capable):

<?xml version="1.0"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="2.0">
    <xsl:output method="xml" indent="yes"/>
    <xsl:template match="/">
    <xsl:for-each select="XML">
        <xsl:for-each select="Active">
            <xsl:value-of select=" replace(current(), 'True','true')"/>
        </xsl:for-each>
    </xsl:for-each>
    </xsl:template>
</xsl:stylesheet>

Exceding the maximum value of a long doesnt throw an exception, instead it cicles back. If you do this:

Long.MAX_VALUE + 1

you will notice that the result is the equivalent to Long.MIN_VALUE.

From here: java number exceeds long.max_value - how to detect?

Anytime you're changing the headers of an HttpWebRequest, you need to use the appropriate properties on the object itself, if they exist. If you have a plain WebRequest, be sure to cast it to an HttpWebRequest first. Then Referrer in your case can be accessed via ((HttpWebRequest)request).Referrer, so you don't need to modify the header directly - just set the property to the right value. ContentLength, ContentType, UserAgent, etc, all need to be set this way.

IMHO, this is a shortcoming on MS part...setting the headers via Headers.Add() should automatically call the appropriate property behind the scenes, if that's what they want to do.

I recently had to revert to a particular revision to debug an older build and this worked like magic:

svn up -r 3340 (or what ever your desired revision number)

I had to resolve all conflicts using "tc" option as I did not care about local changes (checked in everything I cared about prior to reverting)

To get back to head revision was simple too:

svn up

Or, if you want to use minimal "powers" (e.g. if you don't want a cascade delete) to achieve what you want, use

import org.hibernate.annotations.Cascade;
import org.hibernate.annotations.CascadeType;

...

@Cascade({CascadeType.SAVE_UPDATE})
private Set<Child> children;

Use geom_boxplot(outlier.shape = NA) to not display the outliers and scale_y_continuous(limits = c(lower, upper)) to change the axis limits.

An example.

n <- 1e4L
dfr <- data.frame(
  y = exp(rlnorm(n)),  #really right-skewed variable
  f = gl(2, n / 2)
)

p <- ggplot(dfr, aes(f, y)) + 
  geom_boxplot()
p   # big outlier causes quartiles to look too slim

p2 <- ggplot(dfr, aes(f, y)) + 
  geom_boxplot(outlier.shape = NA) +
  scale_y_continuous(limits = quantile(dfr$y, c(0.1, 0.9)))
p2  # no outliers plotted, range shifted

Actually, as Ramnath showed in his answer (and Andrie too in the comments), it makes more sense to crop the scales after you calculate the statistic, via coord_cartesian.

coord_cartesian(ylim = quantile(dfr$y, c(0.1, 0.9)))

(You'll probably still need to use scale_y_continuous to fix the axis breaks.)

What you may want to do is first, on your local machine, make a bare clone of the repository

git clone --bare /path/to/repo /path/to/bare/repo.git  # don't forget the .git!

Now, archive up the new repo.git directory using tar/gzip or whatever your favorite archiving tool is and then copy the archive to the server.

Unarchive the repo on your server. You'll then need to set up a remote on your local repository:

git remote add repo-name user@host:/path/to/repo.git #this assumes you're using SSH

You will then be able to push to and pull from the remote repo with:

git push repo-name branch-name
git pull repo-name branch-name

If you want to delete all rows of a table, you can execute sql command

using (var context = new DataDb())
{
     context.Database.ExecuteSqlCommand("TRUNCATE TABLE [TableName]");
}

TRUNCATE TABLE (Transact-SQL) Removes all rows from a table without logging the individual row deletions. TRUNCATE TABLE is similar to the DELETE statement with no WHERE clause; however, TRUNCATE TABLE is faster and uses fewer system and transaction log resources.

Using new api fetch:

const dataToSend = JSON.stringify({"email": "[email protected]", "password": "101010"});
let dataReceived = ""; 
fetch("", {
    credentials: "same-origin",
    mode: "same-origin",
    method: "post",
    headers: { "Content-Type": "application/json" },
    body: dataToSend
})
    .then(resp => {
        if (resp.status === 200) {
            return resp.json()
        } else {
            console.log("Status: " + resp.status)
            return Promise.reject("server")
        }
    })
    .then(dataJson => {
        dataReceived = JSON.parse(dataJson)
    })
    .catch(err => {
        if (err === "server") return
        console.log(err)
    })

console.log(`Received: ${dataReceived}`)

You're comparing apples to oranges here:

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

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

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

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

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

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

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

Based on your question history, you're using JSF 2.x. So, here's a JSF 2.x targeted answer. In JSF 1.x you would be forced to wrap item values/labels in ugly SelectItem instances. This is fortunately not needed anymore in JSF 2.x.

Basic example

To answer your question directly, just use <f:selectItems> whose value points to a List<T> property which you preserve from the DB during bean's (post)construction. Here's a basic kickoff example assuming that T actually represents a String.

<h:selectOneMenu value="#{bean.name}">
    <f:selectItems value="#{bean.names}" />
</h:selectOneMenu>

with

@ManagedBean
@RequestScoped
public class Bean {

    private String name;
    private List<String> names; 

    @EJB
    private NameService nameService;

    @PostConstruct
    public void init() {
        names = nameService.list();
    }

    // ... (getters, setters, etc)
}

Simple as that. Actually, the T's toString() will be used to represent both the dropdown item label and value. So, when you're instead of List<String> using a list of complex objects like List<SomeEntity> and you haven't overridden the class' toString() method, then you would see com.example.SomeEntity@hashcode as item values. See next section how to solve it properly.

Also note that the bean for <f:selectItems> value does not necessarily need to be the same bean as the bean for <h:selectOneMenu> value. This is useful whenever the values are actually applicationwide constants which you just have to load only once during application's startup. You could then just make it a property of an application scoped bean.

<h:selectOneMenu value="#{bean.name}">
    <f:selectItems value="#{data.names}" />
</h:selectOneMenu>

Complex objects as available items

Whenever T concerns a complex object (a javabean), such as User which has a String property of name, then you could use the var attribute to get hold of the iteration variable which you in turn can use in itemValue and/or itemLabel attribtues (if you omit the itemLabel, then the label becomes the same as the value).

Example #1:

<h:selectOneMenu value="#{bean.userName}">
    <f:selectItems value="#{bean.users}" var="user" itemValue="#{user.name}" />
</h:selectOneMenu>

with

private String userName;
private List<User> users;

@EJB
private UserService userService;

@PostConstruct
public void init() {
    users = userService.list();
}

// ... (getters, setters, etc)

Or when it has a Long property id which you would rather like to set as item value:

Example #2:

<h:selectOneMenu value="#{bean.userId}">
    <f:selectItems value="#{bean.users}" var="user" itemValue="#{user.id}" itemLabel="#{user.name}" />
</h:selectOneMenu>

with

private Long userId;
private List<User> users;

// ... (the same as in previous bean example)

Complex object as selected item

Whenever you would like to set it to a T property in the bean as well and T represents an User, then you would need to bake a custom Converter which converts between User and an unique string representation (which can be the id property). Do note that the itemValue must represent the complex object itself, exactly the type which needs to be set as selection component's value.

<h:selectOneMenu value="#{bean.user}" converter="#{userConverter}">
    <f:selectItems value="#{bean.users}" var="user" itemValue="#{user}" itemLabel="#{user.name}" />
</h:selectOneMenu>

with

private User user;
private List<User> users;

// ... (the same as in previous bean example)

and

@ManagedBean
@RequestScoped
public class UserConverter implements Converter {

    @EJB
    private UserService userService;

    @Override
    public Object getAsObject(FacesContext context, UIComponent component, String submittedValue) {
        if (submittedValue == null || submittedValue.isEmpty()) {
            return null;
        }

        try {
            return userService.find(Long.valueOf(submittedValue));
        } catch (NumberFormatException e) {
            throw new ConverterException(new FacesMessage(String.format("%s is not a valid User ID", submittedValue)), e);
        }
    }

    @Override
    public String getAsString(FacesContext context, UIComponent component, Object modelValue) {
        if (modelValue == null) {
            return "";
        }

        if (modelValue instanceof User) {
            return String.valueOf(((User) modelValue).getId());
        } else {
            throw new ConverterException(new FacesMessage(String.format("%s is not a valid User", modelValue)), e);
        }
    }

}

(please note that the Converter is a bit hacky in order to be able to inject an @EJB in a JSF converter; normally one would have annotated it as @FacesConverter(forClass=User.class), but that unfortunately doesn't allow @EJB injections)

Don't forget to make sure that the complex object class has equals() and hashCode() properly implemented, otherwise JSF will during render fail to show preselected item(s), and you'll on submit face Validation Error: Value is not valid.

public class User {

    private Long id;

    @Override
    public boolean equals(Object other) {
        return (other != null && getClass() == other.getClass() && id != null)
            ? id.equals(((User) other).id)
            : (other == this);
    }

    @Override
    public int hashCode() {
        return (id != null) 
            ? (getClass().hashCode() + id.hashCode())
            : super.hashCode();
    }

}

Complex objects with a generic converter

Head to this answer: Implement converters for entities with Java Generics.

Complex objects without a custom converter

The JSF utility library OmniFaces offers a special converter out the box which allows you to use complex objects in <h:selectOneMenu> without the need to create a custom converter. The SelectItemsConverter will simply do the conversion based on readily available items in <f:selectItem(s)>.

<h:selectOneMenu value="#{bean.user}" converter="omnifaces.SelectItemsConverter">
    <f:selectItems value="#{bean.users}" var="user" itemValue="#{user}" itemLabel="#{user.name}" />
</h:selectOneMenu>

To convert IQuerable or IEnumerable to a list, you can do one of the following:

IQueryable<object> q = ...;
List<object> l = q.ToList();

or:

IQueryable<object> q = ...;
List<object> l = new List<object>(q);

in connection.php: mysqli_set_charset($con,“utf8”); and in sql collation utf=8

foo = "blahblahblah"
bar = "somethingblahblahblahmeep"
if foo in bar:
    # do something

(By the way - try to not name a variable string, since there's a Python standard library with the same name. You might confuse people if you do that in a large project, so avoiding collisions like that is a good habit to get into.)

New location for mysql config file is

In my case where each splash screen was individually designed instead of autogenerated or laid out in a story board format, I had to stick with my Legacy Launch screen configuration and add portrait and landscape images to target iPhoneX 1125×2436 orientations to the config.xml like so:

<splash height="2436" src="resources/ios/splash/Default-2436h.png" width="1125" />
<splash height="1125" src="resources/ios/splash/Default-Landscape-2436h.png" width="2436" />

After adding these to config.xml ("viewport-fit=cover" was already set in index.hml) my app built with Ionic Pro fills the entire screen on iPhoneX devices.

You could use svcutil.exe to generate client code. This would include the definition of the service contract and any data contracts and fault contracts required.

Then, simply delete the client code: classes that implement the service contracts. You'll then need to implement them yourself, in your service.

It's in the python docs.

import datetime
datetime.datetime.combine(datetime.date(2011, 1, 1), 
                          datetime.time(10, 23))

returns

datetime.datetime(2011, 1, 1, 10, 23)

The only reason I'd worry about is that Dog is now allocated on the stack, rather than the heap. So if Dog is megabytes in size, you may have a problem,

If you do need to go the new/delete route, be wary of exceptions. And because of this you should use auto_ptr or one of the boost smart pointer types to manage the object lifetime.

You can just try to establish a TCP connection to a remote host:

public boolean hostAvailable(String host, int port) {
  try (Socket socket = new Socket()) {
    socket.connect(new InetSocketAddress(host, port), 2000);
    return true;
  } catch (IOException e) {
    // Either we have a timeout or unreachable host or failed DNS lookup
    System.out.println(e);
    return false;
  }
}

Then:

boolean online = hostAvailable("www.google.com", 80);

For the v4 LTS version use:

curl --silent --location https://rpm.nodesource.com/setup_4.x | bash -
yum -y install nodejs

For the Node.js v6 use:

curl --silent --location https://rpm.nodesource.com/setup_6.x | bash -
yum -y install nodejs

I also ran into some problems when trying to install native addons on Amazon Linux. If you want to do this you should also install build tools:

yum install gcc-c++ make

I use this code:

bool AlmostEqual(double v1, double v2)
    {
        return (std::fabs(v1 - v2) < std::fabs(std::min(v1, v2)) * std::numeric_limits<double>::epsilon());
    }

For anyone looking to use variable with the match method, this worked for me

var alpha = 'fig';
'food fight'.match(alpha + 'ht')[0]; // fight

Had the same issue but half of your approach didn't work for me . i took the path the way you did :from the output of react-native-cli instal but then manually wrote in ect/pathes with:

sudo nano /etc/paths

at the end i've added the path from output then ctrl x and y to save . Only this way worked but big thanks for the clue!

What about Bootstrap Email? This seems to really nice and compatible with bootstrap 4.

If your application needs to react on request of type post, use this:

if(strtoupper($_SERVER['REQUEST_METHOD']) === 'POST') { // if form submitted with post method
    // validate request, 
    // manage post request differently, 
    // log or don't log request,
    // redirect to avoid resubmition on F5 etc
}

If your application needs to react on any data received through post request, use this:

if(!empty($_POST)) {  // if received any post data
   // process $_POST values, 
   // save data to DB,
   // ... 
}

if(!empty($_FILES)) { // if received any "post" files
   // validate uploaded FILES
   // move to uploaded dir
   // ...
}

It is implementation specific, but you a going to use both, + $_FILES superglobal.

If you use Spring you can use DataSourceInitializer:

@Bean
public DataSourceInitializer dataSourceInitializer(@Qualifier("dataSource") final DataSource dataSource) {
    ResourceDatabasePopulator resourceDatabasePopulator = new ResourceDatabasePopulator();
    resourceDatabasePopulator.addScript(new ClassPathResource("/data.sql"));
    DataSourceInitializer dataSourceInitializer = new DataSourceInitializer();
    dataSourceInitializer.setDataSource(dataSource);
    dataSourceInitializer.setDatabasePopulator(resourceDatabasePopulator);
    return dataSourceInitializer;
}

Used to set up a database during initialization and clean up a database during destruction.

https://docs.spring.io/spring-framework/docs/current/javadoc-api/org/springframework/jdbc/datasource/init/DataSourceInitializer.html

This commonly happened use case for any developer.

It is better to have it as function in your local system. (So better to keep this script in one of the shell profile like ksh/zsh or bash profile based on the user preference)

function killport {
   kill -9 `lsof -i tcp:"$1" | grep LISTEN | awk '{print $2}'`
}

Usage:

killport port_number

Example:

killport 8080

You can find the info here: http://www.php.net/manual/en/language.operators.comparison.php

It's scarce because it wasn't added until PHP4. What you have is fine though, if you know there may be a type difference then it's a much better comparison, since it's testing value and type in the comparison, not just value.

That should work. I am not sure why it's failing. You're quoting your variables properly. What happens if you use this script with double [[ ]]?

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

Double square brackets is a bash extension to [ ]. It doesn't require variables to be quoted, not even if they contain spaces.

Also worth trying: -e to test if a path exists without testing what type of file it is.

In newer version of windows the Certuil has [CertificateStoreName] where we can give the store name. In earlier version windows this was not possible.

Installing *.pfx certificate: certutil -f -p "" -enterprise -importpfx root ""

For more details below command can be executed in windows cmd. C:>certutil -importpfx -? Usage: CertUtil [Options] -importPFX [CertificateStoreName] PFXFile [Modifiers]

In Genymotion just drag and drop the *.apk file in to the emulator and it will automatically installs and runs.

A possible explanation is that the selectlist value that you are binding to is not a string.

So in that example, is the parameter 'PageOptionsDropDown' a string in your model? Because if it isn't then the selected value in the list wouldn't be shown.

It depends on the web application being loaded. Try some of the approaches below:

Set higher render priority (deprecated from API 18+):

webview.getSettings().setRenderPriority(RenderPriority.HIGH);

Enable/disable hardware acceleration:

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
    // chromium, enable hardware acceleration
    webView.setLayerType(View.LAYER_TYPE_HARDWARE, null);
} else {
    // older android version, disable hardware acceleration
    webView.setLayerType(View.LAYER_TYPE_SOFTWARE, null);
}

Disable the cache (if you have problems with your content):

webview.getSettings().setCacheMode(WebSettings.LOAD_NO_CACHE);

Class objects support two kinds of operations: attribute references and instantiation

Attribute references use the standard syntax used for all attribute references in Python: obj.name. Valid attribute names are all the names that were in the class’s namespace when the class object was created. So, if the class definition looked like this:

class MyClass:
    """A simple example class"""
    i = 12345

    def f(self):
        return 'hello world'

then MyClass.i and MyClass.f are valid attribute references, returning an integer and a function object, respectively. Class attributes can also be assigned to, so you can change the value of MyClass.i by assignment. __doc__ is also a valid attribute, returning the docstring belonging to the class: "A simple example class".

Class instantiation uses function notation. Just pretend that the class object is a parameterless function that returns a new instance of the class. For example:

x = MyClass()

The instantiation operation (“calling” a class object) creates an empty object. Many classes like to create objects with instances customized to a specific initial state. Therefore a class may define a special method named __init__(), like this:

def __init__(self):
    self.data = []

When a class defines an __init__() method, class instantiation automatically invokes __init__() for the newly-created class instance. So in this example, a new, initialized instance can be obtained by:

x = MyClass()

Of course, the __init__() method may have arguments for greater flexibility. In that case, arguments given to the class instantiation operator are passed on to __init__(). For example,

class Complex:
    def __init__(self, realpart, imagpart):
        self.r = realpart
        self.i = imagpart

x = Complex(3.0, -4.5)
x.r, x.i

Taken from official documentation which helped me the most in the end.

Here is my example

class Bill():
    def __init__(self,apples,figs,dates):
        self.apples = apples
        self.figs = figs
        self.dates = dates
        self.bill = apples + figs + dates
        print ("Buy",self.apples,"apples", self.figs,"figs 
                and",self.dates,"dates. 
                Total fruitty bill is",self.bill," pieces of fruit :)")

When you create instance of class Bill:

purchase = Bill(5,6,7)

You get:

> Buy 5 apples 6 figs and 7 dates. Total fruitty bill is 18  pieces of
> fruit :)

when using String array, you have to give size of array while initializing

eg

String[] str = new String[10];

you can use index 0-9 to store values

str[0] = "value1"
str[1] = "value2"
str[2] = "value3"
str[3] = "value4"
str[4] = "value5"
str[5] = "value6"
str[6] = "value7"
str[7] = "value8"
str[8] = "value9"
str[9] = "value10"

if you are using ArrayList instread of string array, you can use it without initializing size of array ArrayList str = new ArrayList();

you can add value by using add method of Arraylist

str.add("Value1");

get retrieve a value from arraylist, you can use get method

String s = str.get(0);

find total number of items by size method

int nCount = str.size();

Maybe a bit simpler approach with ngInit and Lodash's debounce method without the need of custom directive:

Controller:

$scope.items = [1, 2, 3, 4];

$scope.refresh = _.debounce(function() {
    // Debounce has timeout and prevents multiple calls, so this will be called 
    // once the iteration finishes
    console.log('we are done');
}, 0);

Template:

<ul>
    <li ng-repeat="item in items" ng-init="refresh()">{{item}}</li>
</ul>

Update

There is even simpler pure AngularJS solution using ternary operator:

Template:

<ul>
    <li ng-repeat="item in items" ng-init="$last ? doSomething() : null">{{item}}</li>
</ul>

Be aware that ngInit uses pre-link compilation phase - i.e. the expression is invoked before child directives are processed. This means that still an asynchronous processing might be required.

You can use JPGraph and Graphpite

element = findElement(By.xpath("//*[@test-id='test-username']");
element = findElement(By.xpath("//input[@test-id='test-username']");

If you're on Ubuntu 16.04 and face the unrecognized service error, these instructions will fix it for you:-

1. Open a terminal window.
2. Issue the command sudo apt-key adv —keyserver hkp://keyserver.ubuntu.com:80 —recv EA312927
3. Issue the command sudo touch /etc/apt/sources.list.d/mongodb-org.list
4. Issue the command sudo gedit /etc/apt/sources.list.d/mongodb-org.list
5. Copy and paste one of the following lines from below (depending upon your release) into the open file. For 12.04: deb http://repo.mongodb.org/apt/ubuntu precise/mongodb-org/3.6 multiverse For 14.04: deb http://repo.mongodb.org/apt/ubuntu trusty/mongodb-org/3.6 multiverse For 16.04: deb http://repo.mongodb.org/apt/ubuntu xenial/mongodb-org/3.6 multiverse

Make sure to edit the version number with the appropriate latest version and save the file.

Installation Open a terminal window and issue command sudo apt-get update && sudo apt-get install -y mongodb-org

Let the installation complete.

Running MongoDB To start the database, issue the command sudo service mongodb start. You should now be able to issue the command to see that MongoDB is running: systemctl status mongodb

Ubuntu 16.04 solution If you are using Ubuntu 16.04, you may run into an issue where you see the error mongodb: unrecognized service due to the switch from upstart to systemd. To get around this, you have to follow these steps.

• If you added the /etc/apt/sources.list.d/mongodb-org.list, remove it with the command sudo rm /etc/apt/sources.list.d/mongodb-org.list

• Update apt with the command sudo apt-get update

• Install the official MongoDB version from the standard repositories with the command sudo apt-get install mongodb in order to get the service set up properly

• Remove what you just installed with the command sudo apt-get remove mongodb && sudo apt-get autoremove

Now follow steps 1 through 5 listed above to install MongoDB; this should re-install the latest version of MongoDB with the systemd services already in place. When you issue the command systemctl status mongodb you should see that the server is active.

I mostly copy pasted the above (with minor modifications and typo fixes) from here - https://www.techrepublic.com/article/how-to-install-mongodb-community-edition-on-ubuntu-linux/

You can/should set your parameter to value to DBNull.Value;

if (variable == "")
{
     cmd.Parameters.Add("@Param", SqlDbType.VarChar, 500).Value = DBNull.Value;
}
else
{
     cmd.Parameters.Add("@Param", SqlDbType.VarChar, 500).Value = variable;
}

Or you can leave your server side set to null and not pass the param at all.

Everything is contained in the .git directory. Just back that up along with your project as you would any file.

For

throw new Exception('test exception');

I got 500 (but didn't see anything in the browser), until I put

php_flag display_errors on

in my .htaccess (just for a subfolder). There are also more detailed settings, see Enabling error display in php via htaccess only

Change visible="false" to style="visibility:hidden" on your tags..

or better use a class to show/hide the labels..

.hidden{
   visibility:hidden;
}

then on your labels add class="hidden"

and with your script remove the class

document.getElementById("endTimeLabel").className = 'hidden'; // to hide

and

document.getElementById("endTimeLabel").className = ''; // to show

Something like this should work, calling the ArrayList constructor that takes a Collection:

List theList = new ArrayList(coll);

In Python 3.6

a, b=1, 2 

print ("Value of variable a is: ", a, "and Value of variable b is :", b)

print(f"Value of a is: {a}")

Logical OR is ||, logical AND is &&. If you need the negation NOT, prefix your expression with !.

Example:

X = (A && B) || C || !D;

Then X will be true when either A and B are true or if C is true or if D is not true (i.e. false).

If you wanted bit-wise AND/OR/NOT, you would use &, | and ~. But if you are dealing with boolean/truth values, you do not want to use those. They do not provide short-circuit evaluation for example due to the way a bitwise operation works.

Other answers would have you disallow a particular number, or tell the user to enter something non-numeric in order to terminate input. Perhaps a better solution is to use std::getline() to read a line of input, then use std::istringstream to read all of the numbers from that line into the vector.

#include <iostream>
#include <sstream>
#include <vector>

int main(int argc, char** argv) {

    std::string line;
    int number;
    std::vector<int> numbers;

    std::cout << "Enter numbers separated by spaces: ";
    std::getline(std::cin, line);
    std::istringstream stream(line);
    while (stream >> number)
        numbers.push_back(number);

    write_vector(numbers);

}

Also, your write_vector() implementation can be replaced with a more idiomatic call to the std::copy() algorithm to copy the elements to an std::ostream_iterator to std::cout:

#include <algorithm>
#include <iterator>

template<class T>
void write_vector(const std::vector<T>& vector) {
    std::cout << "Numbers you entered: ";
    std::copy(vector.begin(), vector.end(),
        std::ostream_iterator<T>(std::cout, " "));
    std::cout << '\n';
}

You can also use std::copy() and a couple of handy iterators to get the values into the vector without an explicit loop:

std::copy(std::istream_iterator<int>(stream),
    std::istream_iterator<int>(),
    std::back_inserter(numbers));

But that’s probably overkill.

You can use this one 24H, seconds are optional

I did some research and found out that byte.Parse is even slower than Convert.ToByte. The fastest conversion I could come up with uses approximately 15 ticks per byte.

    public static byte[] StringToByteArrayFastest(string hex) {
        if (hex.Length % 2 == 1)
            throw new Exception("The binary key cannot have an odd number of digits");

        byte[] arr = new byte[hex.Length >> 1];

        for (int i = 0; i < hex.Length >> 1; ++i)
        {
            arr[i] = (byte)((GetHexVal(hex[i << 1]) << 4) + (GetHexVal(hex[(i << 1) + 1])));
        }

        return arr;
    }

    public static int GetHexVal(char hex) {
        int val = (int)hex;
        //For uppercase A-F letters:
        //return val - (val < 58 ? 48 : 55);
        //For lowercase a-f letters:
        //return val - (val < 58 ? 48 : 87);
        //Or the two combined, but a bit slower:
        return val - (val < 58 ? 48 : (val < 97 ? 55 : 87));
    }

// also works on .NET Micro Framework where (in SDK4.3) byte.Parse(string) only permits integer formats.

Yet another way of getting the last item from a MongoDB Collection (don't mind about the examples):

> db.collection.find().sort({'_id':-1}).limit(1)

Normal Projection

> db.Sports.find()
{ "_id" : ObjectId("5bfb5f82dea65504b456ab12"), "Type" : "NFL", "Head" : "Patriots Won SuperBowl 2017", "Body" : "Again, the Pats won the Super Bowl." }
{ "_id" : ObjectId("5bfb6011dea65504b456ab13"), "Type" : "World Cup 2018", "Head" : "Brazil Qualified for Round of 16", "Body" : "The Brazilians are happy today, due to the qualification of the Brazilian Team for the Round of 16 for the World Cup 2018." }
{ "_id" : ObjectId("5bfb60b1dea65504b456ab14"), "Type" : "F1", "Head" : "Ferrari Lost Championship", "Body" : "By two positions, Ferrari loses the F1 Championship, leaving the Italians in tears." }

Sorted Projection ( _id: reverse order )

> db.Sports.find().sort({'_id':-1})
{ "_id" : ObjectId("5bfb60b1dea65504b456ab14"), "Type" : "F1", "Head" : "Ferrari Lost Championship", "Body" : "By two positions, Ferrari loses the F1 Championship, leaving the Italians in tears." }
{ "_id" : ObjectId("5bfb6011dea65504b456ab13"), "Type" : "World Cup 2018", "Head" : "Brazil Qualified for Round of 16", "Body" : "The Brazilians are happy today, due to the qualification of the Brazilian Team for the Round of 16 for the World Cup 2018." }
{ "_id" : ObjectId("5bfb5f82dea65504b456ab12"), "Type" : "NFL", "Head" : "Patriots Won SuperBowl 2018", "Body" : "Again, the Pats won the Super Bowl" }

sort({'_id':-1}), defines a projection in descending order of all documents, based on their _ids.

Sorted Projection ( _id: reverse order ): getting the latest (last) document from a collection.

> db.Sports.find().sort({'_id':-1}).limit(1)
{ "_id" : ObjectId("5bfb60b1dea65504b456ab14"), "Type" : "F1", "Head" : "Ferrari Lost Championship", "Body" : "By two positions, Ferrari loses the F1 Championship, leaving the Italians in tears." }

"Alter column position" in the PostgreSQL Wiki says:

PostgreSQL currently defines column order based on the attnum column of the pg_attribute table. The only way to change column order is either by recreating the table, or by adding columns and rotating data until you reach the desired layout.

That's pretty weak, but in their defense, in standard SQL, there is no solution for repositioning a column either. Database brands that support changing the ordinal position of a column are defining an extension to SQL syntax.

One other idea occurs to me: you can define a VIEW that specifies the order of columns how you like it, without changing the physical position of the column in the base table.

you can also refactor your solution removing the first loop:

Set<Integer> set = new HashSet<Integer>();
Collection<Integer> removeCandidates = new LinkedList<Integer>(set);

for(Integer element : set)
   if(element % 2 == 0)
       removeCandidates.add(element);

set.removeAll(removeCandidates);

Rather than html encoding your URL parameter, you need to URL encode it:

http://www.facebook.com/sharer.php?&t=FOOBAR&u=http%3A%2F%2Fwww.foobar.com%2F%3Ffirst%3D12%26sec%3D25%26position%3D

You can do this easily in most languages - in javascript:

var encodedParam = encodeURIComponent('www.foobar.com/?first=1&second=12&third=5');
// encodedParam = 'http%3A%2F%2Fwww.foobar.com%2F%3Ffirst%3D12%26sec%3D25%26position%3D'

(there are equivalent methods in other languages too)

You can modify just the two lines:

->where('(library.available_until >=', date("Y-m-d H:i:s"), FALSE)
->or_where("library.available_until = '00-00-00 00:00:00')", NULL, FALSE)

EDIT:

Omitting the FALSE parameter would have placed the backticks before the brackets and make them a part of the table name/value, making the query unusable.

The NULL parameter is there just because the function requires the second parameter to be a value, and since we don't have one, we send NULL.

If you don't care about the difference between an unset variable or a variable with an empty value, you can use the default-value parameter expansion:

foo=${DEPLOY_ENV:-default}

If you do care about the difference, drop the colon

foo=${DEPLOY_ENV-default}

You can also use the -v operator to explicitly test if a parameter is set.

if [[ ! -v DEPLOY_ENV ]]; then
    echo "DEPLOY_ENV is not set"
elif [[ -z "$DEPLOY_ENV" ]]; then
    echo "DEPLOY_ENV is set to the empty string"
else
    echo "DEPLOY_ENV has the value: $DEPLOY_ENV"
fi

Try the following code:

//...
By mySelector = By.xpath("/html/body/div[1]/div/section/div/div[2]/form[1]/div/ul/li");
List<WebElement> myElements = driver.findElements(mySelector);
for(WebElement e : myElements) {
  System.out.println(e.getText());
}

It will returns with the whole content of the <li> tags, like:

<a class="extra">Vše</a> (950)</li>

But you can easily get the number now from it, for example by using split() and/or substring().

Here's a simple function:

function setParent(el, newParent)
{
    newParent.appendChild(el);
}

el's childNodes are the elements to be moved, newParent is the element el will be moved to, so you would execute the function like:

var l = document.getElementById('old-parent').childNodes.length;
var a = document.getElementById('old-parent');
var b = document.getElementById('new-parent');
for (var i = l; i >= 0; i--)
{
    setParent(a.childNodes[0], b);
}

Here is the Demo

The syntax error is just due to a missing alias for the subquery:

select COUNT(*) from
(
select m.Company_id
from Monitor as m
    inner join Monitor_Request as mr on mr.Company_ID=m.Company_id
    group by m.Company_id
    having COUNT(m.Monitor_id)>=5)  mySubQuery  /* Alias */

You have a couple of questions here, so I'll address them separately:

I need to store a number of selected items in one field in a database

My general rule is: don't. This is something which all but requires a second table (or third) with a foreign key. Sure, it may seem easier now, but what if the use case comes along where you need to actually query for those items individually? It also means that you have more options for lazy instantiation and you have a more consistent experience across multiple frameworks/languages. Further, you are less likely to have connection timeout issues (30,000 characters is a lot).

You mentioned that you were thinking about using ENUM. Are these values fixed? Do you know them ahead of time? If so this would be my structure:

Base table (what you have now):

| id primary_key sequence
| -- other columns here.

Items table:

| id primary_key sequence
| descript VARCHAR(30) UNIQUE

Map table:

| base_id  bigint
| items_id bigint

Map table would have foreign keys so base_id maps to Base table, and items_id would map to the items table.

And if you'd like an easy way to retrieve this from a DB, then create a view which does the joins. You can even create insert and update rules so that you're practically only dealing with one table.

What format should I use store the data?

If you have to do something like this, why not just use a character delineated string? It will take less processing power than a CSV, XML, or JSON, and it will be shorter.

What column type should I use store the data?

Personally, I would use TEXT. It does not sound like you'd gain much by making this a BLOB, and TEXT, in my experience, is easier to read if you're using some form of IDE.

Try ctrl+F5, it will hold your Screen until you press any key. Regards

ModRewrite is not the only answer. You could also use Options +MultiViews in .htaccess and then check $_SERVER REQUEST_URI to find everything that is in URL.

You can get the UserProfile path with just this:

Environment.GetFolderPath(Environment.SpecialFolder.UserProfile);

try this

satView.setOnCheckedChangeListener(new android.widget.CompoundButton.OnCheckedChangeListener.OnCheckedChangeListener() {
        @Override
        public void onCheckedChanged(RadioGroup group, int checkedId) {
            if (isChecked){
                // perform logic
            }
        }

    });

I have put this in my partial view:

@HttpContext.Current.Request.RequestContext.RouteData.Values["controller"].ToString()

in the same kind of situation you describe, and it shows the controller described in the URL (Category for you, Product for me), instead of the actual location of the partial view.

So use this alert instead:

alert('@HttpContext.Current.Request.RequestContext.RouteData.Values["controller"].ToString()');

cat find_replace | while read pattern replacement ; do
sed -i "/${pattern}/c ${replacement}" file    
done 

find_replace file contains 2 columns, c1 with pattern to match, c2 with replacement, the sed loop replaces each line conatining one of the pattern of variable 1

You can use cstdlib

Although- http://www.cplusplus.com/articles/j3wTURfi/

#include <cstdlib>

const int dir= system("mkdir -p foo");
if (dir< 0)
{
     return;
}

you can also check if the directory exists already by using

#include <dirent.h>

The Python Magic library provides the functionality you need.

You can install the library with pip install python-magic and use it as follows:

>>> import magic

>>> magic.from_file('iceland.jpg')
'JPEG image data, JFIF standard 1.01'

>>> magic.from_file('iceland.jpg', mime=True)
'image/jpeg'

>>> magic.from_file('greenland.png')
'PNG image data, 600 x 1000, 8-bit colormap, non-interlaced'

>>> magic.from_file('greenland.png', mime=True)
'image/png'

The Python code in this case is calling to libmagic beneath the hood, which is the same library used by the *NIX file command. Thus, this does the same thing as the subprocess/shell-based answers, but without that overhead.

list.insert with any index >= len(of_the_list) places the value at the end of list. It behaves like append

Python 3.7.4
>>>lst=[10,20,30]
>>>lst.insert(len(lst), 101)

I'm also reading an exported file which contains french and German languages. I used Encoding.GetEncoding("iso-8859-1"), true which worked out without any challenges.

Can't import all at once but can use following combination:

ALT + Enter --> Show intention actions and quick-fixes.

F2 --> Next highlighted error.

I also come across same problem, I changed transaction timeout to 15 minutes and it works. I hope this helps.

TransactionOptions options = new TransactionOptions();
options.IsolationLevel = System.Transactions.IsolationLevel.ReadCommitted;
options.Timeout = new TimeSpan(0, 15, 0);
using (TransactionScope scope = new TransactionScope(TransactionScopeOption.Required,options))
{
    sp1();
    sp2();
    ...

}

Using @Pavel's answer as guide, here's a helper method if you don't have the points but have start x,y and height and width. Also can draw inverted/upside down - which is useful for me as it was used as end of vertical barchart.

 private void drawTriangle(int x, int y, int width, int height, boolean inverted, Paint paint, Canvas canvas){

        Point p1 = new Point(x,y);
        int pointX = x + width/2;
        int pointY = inverted?  y + height : y - height;

        Point p2 = new Point(pointX,pointY);
        Point p3 = new Point(x+width,y);


        Path path = new Path();
        path.setFillType(Path.FillType.EVEN_ODD);
        path.moveTo(p1.x,p1.y);
        path.lineTo(p2.x,p2.y);
        path.lineTo(p3.x,p3.y);
        path.close();

        canvas.drawPath(path, paint);
    }

The colClasses vector must have length equal to the number of imported columns. Supposing the rest of your dataset columns are 5:

colClasses=c("character",rep("numeric",5))

Use

// aspect-type.js
class AspectType {

}

export default AspectType;

Then to import it

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

There's no version of it, but the solution isn't hacky at all.

$pos = strpos($haystack, $needle);
if ($pos !== false) {
    $newstring = substr_replace($haystack, $replace, $pos, strlen($needle));
}

Pretty easy, and saves the performance penalty of regular expressions.

Bonus: If you want to replace last occurrence, just use strrpos in place of strpos.

There is Pattern library for data mining.

http://www.clips.ua.ac.be/pages/pattern-web

You can even decide what tags to keep:

s = URL('http://www.clips.ua.ac.be').download()
s = plaintext(s, keep={'h1':[], 'h2':[], 'strong':[], 'a':['href']})
print s

The proper way to get LF endings in Windows is to first set core.autocrlf to false:

git config --global core.autocrlf false

You need to do this if you are using msysgit, because it sets it to true in its system settings.

Now git won’t do any line ending normalization. If you want files you check in to be normalized, do this: Set text=auto in your .gitattributes for all files:

* text=auto

And set core.eol to lf:

git config --global core.eol lf

Now you can also switch single repos to crlf (in the working directory!) by running

git config core.eol crlf

After you have done the configuration, you might want git to normalize all the files in the repo. To do this, go to to the root of your repo and run these commands:

git rm --cached -rf .
git diff --cached --name-only -z | xargs -n 50 -0 git add -f

If you now want git to also normalize the files in your working directory, run these commands:

git ls-files -z | xargs -0 rm
git checkout .

I got this with data driven tests using:

Microsoft Excel Driver (*.xls, *.xlsx, *.xlsm, *.xlsb)

The problem is the above driver only is 32 bit. I had switched visual studio testsettings file to 64 bit to test a 64-bit-only application.

Switching back to 32 bit in the testsettings file fixed the issue.

using a test settings file

I got really tired of going through answers only to find it did not work as expected.

Solution

Make a vbs script to run a hidden batch file which launches the powershell script. Seems silly to make 3 files for this task but atleast the total size is less than 2KB and it runs perfect from tasker or manually (you dont see anything).

scriptName.vbs

Set WinScriptHost = CreateObject("WScript.Shell")
WinScriptHost.Run Chr(34) & "C:\Users\leathan\Documents\scriptName.bat" & Chr(34), 0
Set WinScriptHost = Nothing

scriptName.bat

powershell.exe -ExecutionPolicy Bypass C:\Users\leathan\Documents\scriptName.ps1

    if not os.path.isdir(h):
        mk_dir_recursive(h)

    new_path = join_paths(h, t)
    if not os.path.isdir(new_path):
        os.mkdir(new_path)

Use p{width} for your column specifiers instead of l/r/c.

\begin{tabular}{|p{1cm}|p{3cm}|}
  This text will be wrapped & Some more text \\
\end{tabular}

EDIT: (based on the comments)

\begin{table}[ht]
    \centering
    \begin{tabular}{p{0.35\linewidth} | p{0.6\linewidth}}
      Column 1  & Column2 \\ \hline
      This text will be wrapped & Some more text \\
      Some text here & This text maybe wrapped here if its tooooo long \\
    \end{tabular}
    \caption{Caption}
    \label{tab:my_label}
\end{table}

we get:

Just invert the indexes' order like this:

for (int j = 0; j<array[0].length; j++){
     for (int i = 0; i<array.length; i++){

because all rows has same amount of columns you can use this condition j < array[0].lengt in first for condition due to the fact you are iterating over a matrix

The usage of yield is similar to the keyword return, except that it will return a generator. And the generator object will only traverse once.

yield has two benefits:

1. You do not need to read these values twice;
2. You can get many child nodes but do not have to put them all in memory.

There is another clear explanation maybe help you.

you can simply cast it.

char c = (char)100;

Need to make sure once switched into a frame, need to switch back to default content for accessing webelements in another frames. As Webdriver tend to find the new frame inside the current frame.

driver.switchTo().defaultContent()

There is a blog post with some C# sample code on how to do it here.

It's because you're calling doGet() without actually implementing doGet(). It's the default implementation of doGet() that throws the error saying the method is not supported.

Could you try the correct type for your script tags? I see you use text/Scripts, which is not the right mimetype for javascript.

Use this:

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.6.2/jquery.min.js"></script> 
<script type="text/javascript" src="../Scripts/jquery.dropdownPlain.js"></script>
<script type="text/javascript" src="../Scripts/facebox.js"></script>

end edit

or you could take a look at require.js which is a loader for your javascript code.

depending on your project, this could however be a bit overkill

urllib is a standard library, you do not have to install it. Simply import urllib

I find out the way how to set the image path just remove the "/" before the destination folder as "images/66.jpg" not "/images/66.jpg" And its working fine for me.

This is an example for refreshing data with completely new content. You can easily modify it to fit your needs. I solved this in my case by calling:

notifyItemRangeRemoved(0, previousContentSize);

before:

notifyItemRangeInserted(0, newContentSize);

This is the correct solution and is also mentioned in this post by an AOSP project member.

Horrible Answers Galore

Ozgur Ozcitak

When you cast from signed to unsigned (and vice versa) the internal representation of the number does not change. What changes is how the compiler interprets the sign bit.

This is completely wrong.

Mats Fredriksson

When one unsigned and one signed variable are added (or any binary operation) both are implicitly converted to unsigned, which would in this case result in a huge result.

This is also wrong. Unsigned ints may be promoted to ints should they have equal precision due to padding bits in the unsigned type.

smh

Your addition operation causes the int to be converted to an unsigned int.

Wrong. Maybe it does and maybe it doesn't.

Conversion from unsigned int to signed int is implementation dependent. (But it probably works the way you expect on most platforms these days.)

Wrong. It is either undefined behavior if it causes overflow or the value is preserved.

Anonymous

The value of i is converted to unsigned int ...

Wrong. Depends on the precision of an int relative to an unsigned int.

Taylor Price

As was previously answered, you can cast back and forth between signed and unsigned without a problem.

Wrong. Trying to store a value outside the range of a signed integer results in undefined behavior.

Now I can finally answer the question.

Should the precision of int be equal to unsigned int, u will be promoted to a signed int and you will get the value -4444 from the expression (u+i). Now, should u and i have other values, you may get overflow and undefined behavior but with those exact numbers you will get -4444 [1]. This value will have type int. But you are trying to store that value into an unsigned int so that will then be cast to an unsigned int and the value that result will end up having would be (UINT_MAX+1) - 4444.

Should the precision of unsigned int be greater than that of an int, the signed int will be promoted to an unsigned int yielding the value (UINT_MAX+1) - 5678 which will be added to the other unsigned int 1234. Should u and i have other values, which make the expression fall outside the range {0..UINT_MAX} the value (UINT_MAX+1) will either be added or subtracted until the result DOES fall inside the range {0..UINT_MAX) and no undefined behavior will occur.

What is precision?

Integers have padding bits, sign bits, and value bits. Unsigned integers do not have a sign bit obviously. Unsigned char is further guaranteed to not have padding bits. The number of values bits an integer has is how much precision it has.

[Gotchas]

The macro sizeof macro alone cannot be used to determine precision of an integer if padding bits are present. And the size of a byte does not have to be an octet (eight bits) as defined by C99.

[1] The overflow may occur at one of two points. Either before the addition (during promotion) - when you have an unsigned int which is too large to fit inside an int. The overflow may also occur after the addition even if the unsigned int was within the range of an int, after the addition the result may still overflow.

If you want to commit on top of the current HEAD with the exact state at a different commit, undoing all the intermediate commits, then you can use reset to create the correct state of the index to make the commit.

# Reset the index and working tree to the desired tree
# Ensure you have no uncommitted changes that you want to keep
git reset --hard 56e05fced

# Move the branch pointer back to the previous HEAD
git reset --soft HEAD@{1}

git commit -m "Revert to 56e05fced"

Since you're using JPA, use the Lob annotation (and optionally the Column annotation). Here is what the JPA specification says about it:

9.1.19 Lob Annotation

A Lob annotation specifies that a persistent property or field should be persisted as a large object to a database-supported large object type. Portable applications should use the Lob annotation when mapping to a database Lob type. The Lob annotation may be used in conjunction with the Basic annotation. A Lob may be either a binary or character type. The Lob type is inferred from the type of the persistent field or property, and except for string and character-based types defaults to Blob.

So declare something like this:

@Lob 
@Column(name="CONTENT", length=512)
private String content;

References

• JPA 1.0 specification:
  • Section 9.1.19 "Lob Annotation"

function gitcheckoutall() {
    git diff --name-only --diff-filter=U | sed 's/^/"/;s/$/"/' | xargs git checkout --$1
}

I've added this function in .zshrc file.

Use them this way: gitcheckoutall theirs or gitcheckoutall ours

If you are allowed to change the code of the document inside your iframe and that content is visible only using its parent window, simply add the following CSS in your iframe:

body {
    overflow:hidden;
}

Here a very simple example:

http://jsfiddle.net/u5gLoav9/

This solution allow you to:

• Keep you HTML5 valid as it does not need scrolling="no" attribute on the iframe (this attribute in HTML5 has been deprecated).

• Works on the majority of browsers using CSS overflow:hidden

• No JS or jQuery necessary.

Notes:

To disallow scroll-bars horizontally, use this CSS instead:

overflow-x: hidden;

Extending @marcg solution, you can normally throw and catch a checked exception in Streams; that is, compiler will ask you to catch/re-throw as is you were outside streams!!

@FunctionalInterface
public interface Predicate_WithExceptions<T, E extends Exception> {
    boolean test(T t) throws E;
}

/**
 * .filter(rethrowPredicate(t -> t.isActive()))
 */
public static <T, E extends Exception> Predicate<T> rethrowPredicate(Predicate_WithExceptions<T, E> predicate) throws E {
    return t -> {
        try {
            return predicate.test(t);
        } catch (Exception exception) {
            return throwActualException(exception);
        }
    };
}

@SuppressWarnings("unchecked")
private static <T, E extends Exception> T throwActualException(Exception exception) throws E {
    throw (E) exception;
}

Then, your example would be written as follows (adding tests to show it more clearly):

@Test
public void testPredicate() throws MyTestException {
    List<String> nonEmptyStrings = Stream.of("ciao", "")
            .filter(rethrowPredicate(s -> notEmpty(s)))
            .collect(toList());
    assertEquals(1, nonEmptyStrings.size());
    assertEquals("ciao", nonEmptyStrings.get(0));
}

private class MyTestException extends Exception { }

private boolean notEmpty(String value) throws MyTestException {
    if(value==null) {
        throw new MyTestException();
    }
    return !value.isEmpty();
}

@Test
public void testPredicateRaisingException() throws MyTestException {
    try {
        Stream.of("ciao", null)
                .filter(rethrowPredicate(s -> notEmpty(s)))
                .collect(toList());
        fail();
    } catch (MyTestException e) {
        //OK
    }
}

The computer "name" is resolved from the IP address by the underlying DNS (Domain Name System) library of the OS. There's no universal concept of a computer name across OSes, but DNS is generally available. If the computer name hasn't been configured so DNS can resolve it, it isn't available.

import java.net.InetAddress;
import java.net.UnknownHostException;

String hostname = "Unknown";

try
{
    InetAddress addr;
    addr = InetAddress.getLocalHost();
    hostname = addr.getHostName();
}
catch (UnknownHostException ex)
{
    System.out.println("Hostname can not be resolved");
}

First of all unit tests are, by design, supposed to run completely without interaction.

With that aside, I don't think there's a possibility that was thought of.

You could try hacking with the AllocConsole P/Invoke which will open a console even when your current application is a GUI application. The Console class will then post to the now opened console.

There is no way to create a file without opening it There is os.mknod("newfile.txt") (but it requires root privileges on OSX). The system call to create a file is actually open() with the O_CREAT flag. So no matter how, you'll always open the file.

So the easiest way to simply create a file without truncating it in case it exists is this:

open(x, 'a').close()

Actually you could omit the .close() since the refcounting GC of CPython will close it immediately after the open() statement finished - but it's cleaner to do it explicitely and relying on CPython-specific behaviour is not good either.

In case you want touch's behaviour (i.e. update the mtime in case the file exists):

import os
def touch(path):
    with open(path, 'a'):
        os.utime(path, None)

You could extend this to also create any directories in the path that do not exist:

basedir = os.path.dirname(path)
if not os.path.exists(basedir):
    os.makedirs(basedir)

You could use System.Xml.Linq objects. They were totally redesigned from the old System.Xml days which made constructing XML from scratch really annoying.

Other than the doctype I guess, you could easily do something like:

var html = new XElement("html",
    new XElement("head",
        new XElement("title", "My Page")
    ),
    new XElement("body",
        "this is some text"
    )
);

Add org.hibernate.dialect.OracleDialect for Oracle11g database. It will resolve this error.

You have 2 options:

• You can take the Down from the bad migration and put it in a new migration (you will also need to make the subsequent changes to the model). This is effectively rolling up to a better version.

  I use this option on things that have gone to multiple environments.

• The other option is to actually run Update-Database –TargetMigration: TheLastGoodMigration against your deployed database and then delete the migration from your solution. This is kinda the hulk smash alternative and requires this to be performed against any database deployed with the bad version.

  Note: to rescaffold the migration you can use Add-Migration [existingname] -Force. This will however overwrite your existing migration, so be sure to do this only if you have removed the existing migration from the database. This does the same thing as deleting the existing migration file and running add-migration

  I use this option while developing.

Well you seem to have mistaken them both for what they do.

$(window).height() gets you an unit-less pixel value of the height of the (browser) window aka viewport. With respect to the web browsers the viewport here is visible portion of the canvas(which often is smaller than the document being rendered).

$(document).height() returns an unit-less pixel value of the height of the document being rendered. However, if the actual document’s body height is less than the viewport height then it will return the viewport height instead.

Hope that clears things a little.

Ideas from a twisted mind :

class mytwistedclass{
static std::vector<int> initVector;
mytwistedclass()
{
    //initialise with initVector[0] and then delete it :-)
}

};

now set this initVector to something u want to before u instantiate an object. Then your objects are initialized with your parameters.

Pros:

Clustered indexes work great for ranges (e.g. select * from my_table where my_key between @min and @max)

In some conditions, the DBMS will not have to do work to sort if you use an orderby statement.

Cons:

Clustered indexes are can slow down inserts because the physical layouts of the records have to be modified as records are put in if the new keys are not in sequential order.

Also check out the attr() function of the CSS content attribute. It outputs a given attribute of the element as a text node. Use it like so:

<div class="Owner Joe" />

div:before {
  content: attr(class);
}

Or even with the new HTML5 custom data attributes:

<div data-employeename="Owner Joe" />

div:before {
  content: attr(data-employeename);
}

Hi @daniel.lozynski. Access-Control-Allow-Origin is one of the worst problems web developers face when working with APIs, and I've been working on solutions for a long time.

One way to get rid of Access-Control-Allow-Origin is to use proxies. Of course, proxies sometimes have their own problems.

1. One of their problems is that it slows down your requests.
2. The next problem is that some of these proxies make a small number of requests to you during the day and sometimes leave you with an too many requests error. Of course, this problem is eliminated by switching between proxies.

However, these are all temporary problems and only occur to you during development.

Below is a list of the best proxies I have ever found.

1. https://cors-anywhere.herokuapp.com/
2. https://cors-proxy.htmldriven.com/?url=
3. https://thingproxy.freeboard.io/fetch/
4. https://thingproxy.freeboard.io
5. http://thingproxy.freeboard.io
6. http://www.whateverorigin.org/get?url=
7. http://alloworigin.com/get?url=
8. https://api.allorigins.win/get?url=
9. https://yacdn.org/proxy/

But how to use these proxies?

You can easily equip the API with a proxy and get rid of Access-Control-Allow-Origin by adding any of these addresses before your IP address.

Consider a few examples below:

• https://cors-anywhere.herokuapp.com/http://example.com/posts
• https://thingproxy.freeboard.io/fetch/http://example.com/blog/posts
• https://yacdn.org/proxy/http://example.com/blog/posts

Important:

Use of proxies is limited to online APIs. And you can not use proxies in local APIs. In the following, I will tell you to answer for local APIs as well...

So what do I think is the best solution?

I recently came across a very good Chrome extension that has not had those two proxy problems for me so far and I am very happy with it since I used it.

But the only problem with using this plugin is that you can no longer debug your project on your mobile phone with IP address. This is because this plugin only creates a proxy on your browser and no longer affects data transmission over cable by IP.

You can find and install this plugin from this link.

Allow CORS: Access-Control-Allow-Origin

You can just install this extension on your Chrome browser and have fun...!

Using this plugin is very, very simple and you just need to install it and then activate it. However, if you have a problem with it, on the page of this plugin in 'Chrome Extensions', there is a YouTube video that will completely solve your problems by watching it.

Because my favorite browser is to develop Chrome, I did not look for solutions for other extensions. So if you use Chrome, this plugin will be very useful for you as well.

The answer posted by Mahomedalid has a small problem:

Inside replace function code was replacing "<columns_to_delete>," by "", this replacement has a problem if the field to replace is the last one in the concat string due to the last one doesn't have the char comma "," and is not removed from the string.

My proposal:

SET @sql = CONCAT('SELECT ', (SELECT REPLACE(GROUP_CONCAT(COLUMN_NAME),
                  '<columns_to_delete>', '\'FIELD_REMOVED\'')
           FROM INFORMATION_SCHEMA.COLUMNS
           WHERE TABLE_NAME = '<table>'
             AND TABLE_SCHEMA = '<database>'), ' FROM <table>');

Replacing <table>, <database> and `

The column removed is replaced by the string "FIELD_REMOVED" in my case this works because I was trying to safe memory. (The field I was removing is a BLOB of around 1MB)

There are three methods:

• First shutdown your Tomcat from the its bin directory (sh shutdown.sh). Then delete all the content of your Tomcat webapps folder (rm -fr *). Then rename your WAR file to ROOT.war, and finally start your Tomcat from the bin directory (sh startup.sh).

• Leave your war file in $CATALINA_BASE/webapps under its original name. Turn off autoDeploy and deployOnStartup in your Host element in the server.xml file. Explicitly define all application Contexts in server.xml, specifying both the path and docBase attributes. You must do this because you have disabled all the Tomcat auto-deploy mechanisms, and Tomcat will not deploy your applications anymore unless it finds their Context in the server.xml.

  second method: in order to make any change to any application, you will have to stop and restart Tomcat.

• Place your WAR file outside of $CATALINA_BASE/webapps (it must be outside to prevent double deployment). Place a context file named ROOT.xml in $CATALINA_BASE/conf/. The single element in this context file MUST have a docBase attribute pointing to the location of your WAR file. The path element should not be set - it is derived from the name of the .xml file, in this case ROOT.xml. See the documentation for the Context container for details.

Haskell's standard list data type forall t. [t] in implementation closely resembles a canonical C linked list, and shares its essentially properties. Linked lists are very different from arrays. Most notably, access by index is a O(n) linear-, instead of a O(1) constant-time operation.

If you require frequent random access, consider the Data.Array standard.

!! is an unsafe partially defined function, provoking a crash for out-of-range indices. Be aware that the standard library contains some such partial functions (head, last, etc.). For safety, use an option type Maybe, or the Safe module.

Example of a reasonably efficient, robust total (for indices = 0) indexing function:

data Maybe a = Nothing | Just a

lookup :: Int -> [a] -> Maybe a
lookup _ []       = Nothing
lookup 0 (x : _)  = Just x
lookup i (_ : xs) = lookup (i - 1) xs

Working with linked lists, often ordinals are convenient:

nth :: Int -> [a] -> Maybe a
nth _ []       = Nothing
nth 1 (x : _)  = Just x
nth n (_ : xs) = nth (n - 1) xs

To support older version Space can be replaced with View as below. Add this view between after left most component and before right most component. This view with weight=1 will stretch and fill the space

    <View
        android:layout_width="0dp"
        android:layout_height="20dp"
        android:layout_weight="1" />

Complete sample code is given here. It has has 4 components. Two arrows will be on the right and left side. The Text and Spinner will be in the middle.

    <ImageButton
        android:id="@+id/btnGenesis"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center|center_vertical"
        android:layout_marginBottom="2dp"

****In Swift 3****

To create border

 btnName.layer.borderWidth = 1
 btnName.layer.borderColor = UIColor.black.cgColor

To make corner rounded

 btnName.layer.cornerRadius = 5

Do you mean like:

$val1 = rand( 1, 10 ); // gives one integer between 1 and 10
$val2 = rand( 20, 40 ) ; // gives one integer between 20 and 40

or perhaps:

$range = range( 1, 10 ); // gives array( 1, 2, ..., 10 );
$range2 = range( 20, 40 ); // gives array( 20, 21, ..., 40 );

or maybe:

$truth1 = $val >= 1 && $val <= 10; // true if 1 <= x <= 10
$truth2 = $val >= 20 && $val <= 40; // true if 20 <= x <= 40

suppose you wanted:

$in_range = ( $val > 1 && $val < 10 ) || ( $val > 20 && $val < 40 ); // true if 1 < x < 10 OR 20 < x < 40

It's easy to get this error in a multi-module project. If, for example, you made changes to modules A, B, and C, but then you try to compile just module B, you are susceptible to this error. Say module B has a dependency on module A. Since only module B was compiled, the class files from module A are now out of date and possibly invalid.

Compiling all the modules (or modules in the proper hierarchical dependency order) resolves this error, if this is the nature of your problem.

This is how you save the relevant file as a Excel12 (.xlsx) file... It is not as you would intuitively think i.e. using Excel.XlFileFormat.xlExcel12 but Excel.XlFileFormat.xlOpenXMLWorkbook. The actual C# command was

excelWorkbook.SaveAs(strFullFilePathNoExt, Excel.XlFileFormat.xlOpenXMLWorkbook, Missing.Value,
    Missing.Value, false, false, Excel.XlSaveAsAccessMode.xlNoChange, 
    Excel.XlSaveConflictResolution.xlUserResolution, true, 
    Missing.Value, Missing.Value, Missing.Value);

I hope this helps someone else in the future.

Missing.Value is found in the System.Reflection namespace.

Try this :

<style type="text/css">
        .myTableStyle
        {
           position:absolute;
           top:50%;
           left:50%; 

            /*Alternatively you could use: */
           /*
              position: fixed;
               bottom: 50%;
               right: 50%;
           */


        }
    </style>

try

 String s = "SALES:0,SALE_PRODUCTS:1,EXPENSES:2,EXPENSES_ITEMS:3";
    HashMap<String,Integer> hm =new HashMap<String,Integer>();
    for(String s1:s.split(",")){
       String[] s2 = s1.split(":");
        hm.put(s2[0], Integer.parseInt(s2[1]));
    }

the way most developers will do is:

<div id="web-title">
   <a href="http://website.com" title="Website" rel="home">
       <span class="webname">Website Name</span>
   </a>
</div>

.webname {
   display: none;
}

I used to do it too, until i realized that you are hiding content for devices. aka screen-readers and such.

So by passing:

#web-title span {text-indent: -9000em;}

you ensure that the text still is readable.

The whole :action =>, :controller => bit that I've seen around a lot didn't work for me.

Spent hours digging and this method definitely worked for me in a loop.

<%=link_to( image_tag(participant.user.profile_pic.url(:small)), user_path(participant.user), :class=>"work") %>

Ruby on Rails using link_to with image_tag

Also, I'm using Rails 4.

In order to format a date as e.g. 10-Aug-2010, you might want to use .toDateString() and ES6 array destructuring.

const formattedDate = new Date().toDateString()
// The above yields e.g. 'Mon Jan 06 2020'

const [, month, day, year] = formattedDate.split(' ')

const ddMmmYyyy = `${day}-${month}-${year}`
// or
const ddMmmYyyy = [day, month, year].join('-')

Probably there's something wrong with the input values for X and/or T. The function from the question works ok:

import numpy as np
from math import e

def sigmoid(X, T):
  return 1.0 / (1.0 + np.exp(-1.0 * np.dot(X, T)))

X = np.array([[1, 2, 3], [5, 0, 0]])
T = np.array([[1, 2], [1, 1], [4, 4]])

print(X.dot(T))
# Just to see if values are ok
print([1. / (1. + e ** el) for el in [-5, -10, -15, -16]])
print()
print(sigmoid(X, T))

Result:

[[15 16]
 [ 5 10]]

[0.9933071490757153, 0.9999546021312976, 0.999999694097773, 0.9999998874648379]

[[ 0.99999969  0.99999989]
 [ 0.99330715  0.9999546 ]]

Probably it's the dtype of your input arrays. Changing X to:

X = np.array([[1, 2, 3], [5, 0, 0]], dtype=object)

Gives:

Traceback (most recent call last):
  File "/[...]/stackoverflow_sigmoid.py", line 24, in <module>
    print sigmoid(X, T)
  File "/[...]/stackoverflow_sigmoid.py", line 14, in sigmoid
    return 1.0 / (1.0 + np.exp(-1.0 * np.dot(X, T)))
AttributeError: exp

Within Java 7 you can define multiple catch clauses like:

catch (IllegalArgumentException | SecurityException e)
{
    ...
}

You could replace the original jQuery addClass and removeClass functions with your own that would call the original functions and then trigger a custom event. (Using a self-invoking anonymous function to contain the original function reference)

(function( func ) {
    $.fn.addClass = function() { // replace the existing function on $.fn
        func.apply( this, arguments ); // invoke the original function
        this.trigger('classChanged'); // trigger the custom event
        return this; // retain jQuery chainability
    }
})($.fn.addClass); // pass the original function as an argument

(function( func ) {
    $.fn.removeClass = function() {
        func.apply( this, arguments );
        this.trigger('classChanged');
        return this;
    }
})($.fn.removeClass);

Then the rest of your code would be as simple as you'd expect.

$(selector).on('classChanged', function(){ /*...*/ });

Update:

This approach does make the assumption that the classes will only be changed via the jQuery addClass and removeClass methods. If classes are modified in other ways (such as direct manipulation of the class attribute through the DOM element) use of something like MutationObservers as explained in the accepted answer here would be necessary.

Also as a couple improvements to these methods:

• Trigger an event for each class being added (classAdded) or removed (classRemoved) with the specific class passed as an argument to the callback function and only triggered if the particular class was actually added (not present previously) or removed (was present previously)

• Only trigger classChanged if any classes are actually changed

  (function( func ) {
      $.fn.addClass = function(n) { // replace the existing function on $.fn
          this.each(function(i) { // for each element in the collection
              var $this = $(this); // 'this' is DOM element in this context
              var prevClasses = this.getAttribute('class'); // note its original classes
              var classNames = $.isFunction(n) ? n(i, prevClasses) : n.toString(); // retain function-type argument support
              $.each(classNames.split(/\s+/), function(index, className) { // allow for multiple classes being added
                  if( !$this.hasClass(className) ) { // only when the class is not already present
                      func.call( $this, className ); // invoke the original function to add the class
                      $this.trigger('classAdded', className); // trigger a classAdded event
                  }
              });
              prevClasses != this.getAttribute('class') && $this.trigger('classChanged'); // trigger the classChanged event
          });
          return this; // retain jQuery chainability
      }
  })($.fn.addClass); // pass the original function as an argument
  
  (function( func ) {
      $.fn.removeClass = function(n) {
          this.each(function(i) {
              var $this = $(this);
              var prevClasses = this.getAttribute('class');
              var classNames = $.isFunction(n) ? n(i, prevClasses) : n.toString();
              $.each(classNames.split(/\s+/), function(index, className) {
                  if( $this.hasClass(className) ) {
                      func.call( $this, className );
                      $this.trigger('classRemoved', className);
                  }
              });
              prevClasses != this.getAttribute('class') && $this.trigger('classChanged');
          });
          return this;
      }
  })($.fn.removeClass);
  

With these replacement functions you can then handle any class changed via classChanged or specific classes being added or removed by checking the argument to the callback function:

$(document).on('classAdded', '#myElement', function(event, className) {
    if(className == "something") { /* do something */ }
});

A very direct way is to just use read.table on your character vector:

> read.table(text = text, sep = ".", colClasses = "character")
   V1 V2  V3  V4
1   F US CLE V13
2   F US CA6 U13
3   F US CA6 U13
4   F US CA6 U13
5   F US CA6 U13
6   F US CA6 U13
7   F US CA6 U13
8   F US CA6 U13
9   F US  DL U13
10  F US  DL U13
11  F US  DL U13
12  F US  DL Z13
13  F US  DL Z13

colClasses needs to be specified, otherwise F gets converted to FALSE (which is something I need to fix in "splitstackshape", otherwise I would have recommended that :) )

Update (> a year later)...

Alternatively, you can use my cSplit function, like this:

cSplit(as.data.table(text), "text", ".")
#     text_1 text_2 text_3 text_4
#  1:      F     US    CLE    V13
#  2:      F     US    CA6    U13
#  3:      F     US    CA6    U13
#  4:      F     US    CA6    U13
#  5:      F     US    CA6    U13
#  6:      F     US    CA6    U13
#  7:      F     US    CA6    U13
#  8:      F     US    CA6    U13
#  9:      F     US     DL    U13
# 10:      F     US     DL    U13
# 11:      F     US     DL    U13
# 12:      F     US     DL    Z13
# 13:      F     US     DL    Z13

Or, separate from "tidyr", like this:

library(dplyr)
library(tidyr)

as.data.frame(text) %>% separate(text, into = paste("V", 1:4, sep = "_"))
#    V_1 V_2 V_3 V_4
# 1    F  US CLE V13
# 2    F  US CA6 U13
# 3    F  US CA6 U13
# 4    F  US CA6 U13
# 5    F  US CA6 U13
# 6    F  US CA6 U13
# 7    F  US CA6 U13
# 8    F  US CA6 U13
# 9    F  US  DL U13
# 10   F  US  DL U13
# 11   F  US  DL U13
# 12   F  US  DL Z13
# 13   F  US  DL Z13

Having run both queries on a SQL Server 2012 instance, I can confirm the first query was fastest in my case.

The query with the LIKE keyword showed a clustered index scan.

The CONTAINS also had a clustered index scan with additional operators for the full text match and a merge join.

I wrote this comment already more than 4 years ago and decided now to make it to an answer.

The script from jruzafa can be a bit simplified:

#!/bin/bash

USER="zend"
PASSWORD=""
ExcludeDatabases="Database|information_schema|performance_schema|mysql"
databases=`mysql -u $USER -p$PASSWORD -e "SHOW DATABASES;" | tr -d "| " | egrep -v $ExcludeDatabases`

for db in $databases; do
    echo "Dumping database: $db"
    mysqldump -u $USER -p$PASSWORD --databases $db > `date +%Y%m%d`.$db.sql
    # gzip $OUTPUT`date +%Y%m%d`.$db.sql
done

Note:

1. The excluded databases - prevalently the system tables - are provided in the variable ExcludeDatabases
2. Please be aware that the password is provided in the command line. This is considered as insecure. Study this question.

Found one solution for WIFI (works for Android 4.3, 4.4):

1. Connect to WIFI network (e.g. 'Alex')
2. Settings->WIFI
3. Long tap on connected network's name (e.g. on 'Alex')
4. Modify network config-> Show advanced options
5. Set proxy settings

If you reaallly have to do this... it'll take reflection and quite some time to do this. Event handlers are managed in an event-to-delegate-map inside a control. You would need to

• Reflect and obtain this map in the control instance.
• Iterate for each event, get the delegate
  • each delegate in turn could be a chained series of event handlers. So call obControl.RemoveHandler(event, handler)

In short, a lot of work. It is possible in theory... I never tried something like this.

See if you can have better control/discipline over the subscribe-unsubscribe phase for the control.

This should work in C++11 without boost:
