If you have problems with numbers (say 1, 2, 10, 12 which will be sorted 1, 10, 12, 2) you can use LINQ:

var arr = arr.OrderBy(x=>x).ToArray();

In my case I had all of the proper references in my project. I found that by building the solution the nuget packages were automatically restored.

I just had this issue. I noticed that even after I closed my browser I had many Chrome processes running. Turns out these were each from my Chrome extension.

Under advanced settings I unchecked 'Continue running background apps when Google Chrome is closed' and my session cookies started working as they should.

Still a pain in the rear for all of us developers that have been coding expecting that session cookies would get cleared when the user is done browsing.

Use Convert.ToInt32() for conversion. You can have a look at How to convert string to ASCII value in C# and ASCII values.

In Laravel 5.2 Input:: is replaced with Request::

use

Request::

Add to the top of Controller or any other Class

use Illuminate\Http\Request;

I believe that, as stated above, using d2.update(d1) is the best approach and that you can also copy d2 first if you still need it.

Although, I want to point out that dict(d1, **d2) is actually a bad way to merge dictionnaries in general since keyword arguments need to be strings, thus it will fail if you have a dict such as:

{
  1: 'foo',
  2: 'bar'
}

Another silly mistake you can do is copy recursive function from non class environment to class and don`t change inner self calls to $this->method_name()

i`m writing this because couldn`t understand why i got this error and this thread is first in google when you search for this error.

Use the Chart Wizard.

On Step 2 of 4, there is a tab labeled "Series". There are 3 fields and a list box on this tab. The list box shows the different series you are already including on the chart. Each series has both a "Name" field and a "Values" field that is specific to that series. The final field is the "Category (X) axis labels" field, which is common to all series.

Click on the "Add" button below the list box. This will add a blank series to your list box. Notice that the values for "Name" and for "Values" change when you highlight a series in the list box.

Select your new series.

There is an icon in each field on the right side. This icon allows you to select cells in the workbook to pull the data from. When you click it, the Wizard temporarily hides itself (except for the field you are working in) allowing you to interact with the workbook.

Select the appropriate sheet in the workbook and then select the fields with the data you want to show in the chart. The button on the right of the field can be clicked to unhide the wizard.

Hope that helps.

EDIT: The above applies to 2003 and before. For 2007, when the chart is selected, you should be able to do a similar action using the "Select Data" option on the "Design" tab of the ribbon. This opens up a dialog box listing the Series for the chart. You can select the series just as you could in Excel 2003, but you must use the "Add" and "Edit" buttons to define custom series.

Maybe this would help:

String[] some_array = getResources().getStringArray(R.array.your_string_array)

So you get the array-list as a String[] and then choose any i, some_array[i].

I found more accurate way to adding views like linear layouts in kotlin (Pass parent layout in inflate() and false)

val parentLayout = view.findViewById<LinearLayout>(R.id.llRecipientParent)
val childView = layoutInflater.inflate(R.layout.layout_recipient, parentLayout, false)
parentLayout.addView(childView)

Simplest solution:

$converted_res = $res ? 'true' : 'false';

May I suggest Node ORM?

https://github.com/dresende/node-orm2

There's documentation on the Readme, supports MySQL, PostgreSQL and SQLite.

MongoDB is available since version 2.1.x (released in July 2013)

UPDATE: This package is no longer maintained, per the project's README. It instead recommends bookshelf and sequelize

Here's a nifty little extension method that you can use if you want to check guid uniqueness in many places in your code.

internal static class GuidExt
{
    public static bool IsUnique(this Guid guid)
    {
        while (guid != Guid.NewGuid())
        { }
        return false;
    }
}

To call it, simply call Guid.IsUnique whenever you generate a new guid...

Guid g = Guid.NewGuid();
if (!g.IsUnique())
{
    throw new GuidIsNotUniqueException();
}

...heck, I'd even recommend calling it twice to make sure it got it right in the first round.

We do it this way...

String.prototype.getValueByKey = function (k) {
    var p = new RegExp('\\b' + k + '\\b', 'gi');
    return this.search(p) != -1 ? decodeURIComponent(this.substr(this.search(p) + k.length + 1).substr(0, this.substr(this.search(p) + k.length + 1).search(/(&|;|$)/))) : "";
};

Technically, you can't return more than one value. However, there are multiple ways to work around that limitation. The way that acts most like returning multiple values, is with the list keyword:

function getXYZ()
{
    return array(4,5,6);
}

list($x,$y,$z) = getXYZ();

// Afterwards: $x == 4 && $y == 5 && $z == 6
// (This will hold for all samples unless otherwise noted)

Technically, you're returning an array and using list to store the elements of that array in different values instead of storing the actual array. Using this technique will make it feel most like returning multiple values.

The list solution is a rather php-specific one. There are a few languages with similar structures, but more languages that don't. There's another way that's commonly used to "return" multiple values and it's available in just about every language (in one way or another). However, this method will look quite different so may need some getting used to.

// note that I named the arguments $a, $b and $c to show that
// they don't need to be named $x, $y and $z
function getXYZ(&$a, &$b, &$c)
{
    $a = 4;
    $b = 5;
    $c = 6; 
}

getXYZ($x, $y, $z);

This technique is also used in some functions defined by php itself (e.g. $count in str_replace, $matches in preg_match). This might feel quite different from returning multiple values, but it is worth at least knowing about.

A third method is to use an object to hold the different values you need. This is more typing, so it's not used quite as often as the two methods above. It may make sense to use this, though, when using the same set of variables in a number of places (or of course, working in a language that doesn't support the above methods or allows you to do this without extra typing).

class MyXYZ
{
    public $x;
    public $y;
    public $z;
}

function getXYZ()
{
    $out = new MyXYZ();
    
    $out->x = 4;
    $out->y = 5;
    $out->z = 6;
    
    return $out;
}

$xyz = getXYZ();

$x = $xyz->x;
$y = $xyz->y;
$z = $xyz->z;

The above methods sum up the main ways of returning multiple values from a function. However, there are variations on these methods. The most interesting variations to look at, are those in which you are actually returning an array, simply because there's so much you can do with arrays in PHP.

First, we can simply return an array and not treat it as anything but an array:

function getXYZ()
{
    return array(1,2,3);
}

$array = getXYZ();

$x = $array[0];
$y = $array[1];
$z = $array[2];

The most interesting part about the code above is that the code inside the function is the same as in the very first example I provided; only the code calling the function changed. This means that it's up to the one calling the function how to treat the result the function returns.

Alternatively, one could use an associative array:

function getXYZ()
{
    return array('x' => 4,
                 'y' => 5,
                 'z' => 6);
}

$array = getXYZ();

$x = $array['x'];
$y = $array['y'];
$z = $array['z'];

Php does have the compact function that allows you to do same as above but while writing less code. (Well, the sample won't have less code, but a real world application probably would.) However, I think the amount of typing saving is minimal and it makes the code harder to read, so I wouldn't do it myself. Nevertheless, here's a sample:

function getXYZ()
{
    $x = 4;
    $y = 5;
    $z = 6;
    
    return compact('x', 'y', 'z');
}

$array = getXYZ();

$x = $array['x'];
$y = $array['y'];
$z = $array['z'];

It should be noted that while compact does have a counterpart in extract that could be used in the calling code here, but since it's a bad idea to use it (especially for something as simple as this) I won't even give a sample for it. The problem is that it will do "magic" and create variables for you, while you can't see which variables are created without going to other parts of the code.

Finally, I would like to mention that list doesn't really play well with associative array. The following will do what you expect:

function getXYZ()
{
    return array('x' => 4,
                 'y' => 5,
                 'z' => 6);
}

$array = getXYZ();

list($x, $y, $z) = getXYZ();

However, the following will do something different:

function getXYZ()
{
    return array('x' => 4,
                 'z' => 6,
                 'y' => 5);
}

$array = getXYZ();

list($x, $y, $z) = getXYZ();

// Pay attention: $y == 6 && $z == 5

If you used list with an associative array, and someone else has to change the code in the called function in the future (which may happen just about any situation) it may suddenly break, so I would recommend against combining list with associative arrays.

Had the same problem, it turned out it was the WindowsFirewall blocking connections. Try to disable WindowsFirewall for a while to see if helps and if it is the problem open ports as needed.

What if you don't immediately set the button to disabled, but delay that through setTimeout? Your 'disable' function would return and the submit would continue.

See this answer: there is in Ruby 1.9.2, but not in earlier versions. Personally I think rand(8) + 3 is fine, but if you're interested check out the Random class described in the link.

You need to change the seed.

int main() {

    srand(time(NULL));
    cout << (rand() % 101);
    return 0;
}

the srand seeding thing is true also for a c language code.

I only use Elastic-search. Since I found solr is very hard to start. Elastic-search's features:

1. Easy to start, very few setting. Even a newbie can setup a cluster step by step.
2. Simple Restful API which using NoSQL query. And many language libraries for easy accessing.
3. Good document, you can read the book: . There is a web version on official website.

vector<vector> matrix(row, vector(col, 0));

This will initialize a 2D vector of rows=row and columns = col with all initial values as 0. No need to initialize and use resize.

Since the vector is initialized with size, you can use "[]" operator as in array to modify the vector.

matrix[x][y] = 2;

Documented couple of design issues with this in a comment above. Short story, in Oracle, you need to limit the results manually when you have large tables and/or tables with same column names (and you don't want to explicit type them all out and rename them all). Easy solution is to figure out your breakpoint and limit that in your query. Or you could also do this in the inner query if you don't have the conflicting column names constraint. E.g.

WHERE m_api_log.created_date BETWEEN TO_DATE('10/23/2015 05:00', 'MM/DD/YYYY HH24:MI') 
                                 AND TO_DATE('10/30/2015 23:59', 'MM/DD/YYYY HH24:MI')  

will cut down the results substantially. Then you can ORDER BY or even do the outer query to limit rows.

Also, I think TOAD has a feature to limit rows; but, not sure that does limiting within the actual query on Oracle. Not sure.

On Windows pip3 should be in the Scripts path of your Python installation:

C:\path\to\python\Scripts\pip3

Use:

where python

to find out where your Python executable(s) is/are located. The result should look like this:

C:\path\to\python\python.exe

or:

C:\path\to\python\python3.exe

You can check if pip3 works with this absolute path:

C:\path\to\python\Scripts\pip3

if yes, add C:\path\to\python\Scripts to your environmental variable PATH .

We can use following code

textBox1.DataBindings.Add("Text", model, "Name", false, DataSourceUpdateMode.OnPropertyChanged);

Where

• "Text" – the property of textbox
• model – the model object enter code here
• "Name" – the value of model which to bind the textbox.

We, the Javascript lovers, don't have to use Ruby (Jekyll or Octopress) to generate static pages in Github pages, we can use Node.js and Harp, for example:

These are the steps. Abstract:

1. Create a New Repository

2. Clone the Repository

   git clone https://github.com/your-github-user-name/your-github-user-name.github.io.git
   

3. Initialize a Harp app (locally):

   harp init _harp
   

make sure to name the folder with an underscore at the beginning; when you deploy to GitHub Pages, you don’t want your source files to be served.

4. Compile your Harp app

   harp compile _harp ./
   

5. Deploy to Gihub

   git add -A
   git commit -a -m "First Harp + Pages commit"
   git push origin master
   

And this is a cool tutorial with details about nice stuff like layouts, partials, Jade and Less.

I believe the intent was to rename System32, but so many applications hard-coded for that path, that it wasn't feasible to remove it.

SysWoW64 wasn't intended for the dlls of 64-bit systems, it's actually something like "Windows on Windows64", meaning the bits you need to run 32bit apps on a 64bit windows.

This article explains a bit:

"Windows x64 has a directory System32 that contains 64-bit DLLs (sic!). Thus native processes with a bitness of 64 find “their” DLLs where they expect them: in the System32 folder. A second directory, SysWOW64, contains the 32-bit DLLs. The file system redirector does the magic of hiding the real System32 directory for 32-bit processes and showing SysWOW64 under the name of System32."

Edit: If you're talking about an installer, you really should not hard-code the path to the system folder. Instead, let Windows take care of it for you based on whether or not your installer is running on the emulation layer.

You create the relationships the other way around; add foreign keys to the Person type to create a Many-to-One relationship:

class Person(models.Model):
    name = models.CharField(max_length=50)
    birthday = models.DateField()
    anniversary = models.ForeignKey(
        Anniversary, on_delete=models.CASCADE)
    address = models.ForeignKey(
        Address, on_delete=models.CASCADE)

class Address(models.Model):
    line1 = models.CharField(max_length=150)
    line2 = models.CharField(max_length=150)
    postalcode = models.CharField(max_length=10)
    city = models.CharField(max_length=150)
    country = models.CharField(max_length=150)

class Anniversary(models.Model):
    date = models.DateField()

Any one person can only be connected to one address and one anniversary, but addresses and anniversaries can be referenced from multiple Person entries.

Anniversary and Address objects will be given a reverse, backwards relationship too; by default it'll be called person_set but you can configure a different name if you need to. See Following relationships "backward" in the queries documentation.

Well you can try this.

  <object data="URL_TO_Default_img.png" type="image/png">

1. A Buffer is just a view for looking into an ArrayBuffer.

A Buffer, in fact, is a FastBuffer, which extends (inherits from) Uint8Array, which is an octet-unit view (“partial accessor”) of the actual memory, an ArrayBuffer.

class FastBuffer extends Uint8Array {
  constructor(arg1, arg2, arg3) {
    super(arg1, arg2, arg3);
  }
}
FastBuffer.prototype.constructor = Buffer;
internalBuffer.FastBuffer = FastBuffer;

Buffer.prototype = FastBuffer.prototype;

2. The size of an ArrayBuffer and the size of its view may vary.

Reason #1: Buffer.from(arrayBuffer[, byteOffset[, length]]).

With Buffer.from(arrayBuffer[, byteOffset[, length]]), you can create a Buffer with specifying its underlying ArrayBuffer and the view's position and size.

const test_buffer = Buffer.from(new ArrayBuffer(50), 40, 10);
console.info(test_buffer.buffer.byteLength); // 50; the size of the memory.
console.info(test_buffer.length); // 10; the size of the view.

Reason #2: FastBuffer's memory allocation.

It allocates the memory in two different ways depending on the size.

• If the size is less than the half of the size of a memory pool and is not 0 (“small”): it makes use of a memory pool to prepare the required memory.
• Else: it creates a dedicated ArrayBuffer that exactly fits the required memory.

function allocate(size) {
  if (size <= 0) {
    return new FastBuffer();
  }
  if (size < (Buffer.poolSize >>> 1)) {
    if (size > (poolSize - poolOffset))
      createPool();
    var b = new FastBuffer(allocPool, poolOffset, size);
    poolOffset += size;
    alignPool();
    return b;
  } else {
    return createUnsafeBuffer(size);
  }
}

function createUnsafeBuffer(size) {
  return new FastBuffer(createUnsafeArrayBuffer(size));
}

What do you mean by a “memory pool?”

A memory pool is a fixed-size pre-allocated memory block for keeping small-size memory chunks for Buffers. Using it keeps the small-size memory chunks tightly together, so prevents fragmentation caused by separate management (allocation and deallocation) of small-size memory chunks.

In this case, the memory pools are ArrayBuffers whose size is 8 KiB by default, which is specified in Buffer.poolSize. When it is to provide a small-size memory chunk for a Buffer, it checks if the last memory pool has enough available memory to handle this; if so, it creates a Buffer that “views” the given partial chunk of the memory pool, otherwise, it creates a new memory pool and so on.

You can access the underlying ArrayBuffer of a Buffer. The Buffer's buffer property (that is, inherited from Uint8Array) holds it. A “small” Buffer's buffer property is an ArrayBuffer that represents the entire memory pool. So in this case, the ArrayBuffer and the Buffer varies in size.

const zero_sized_buffer = Buffer.allocUnsafe(0);
const small_buffer = Buffer.from([0xC0, 0xFF, 0xEE]);
const big_buffer = Buffer.allocUnsafe(Buffer.poolSize >>> 1);

// A `Buffer`'s `length` property holds the size, in octets, of the view.
// An `ArrayBuffer`'s `byteLength` property holds the size, in octets, of its data.

console.info(zero_sized_buffer.length); /// 0; the view's size.
console.info(zero_sized_buffer.buffer.byteLength); /// 0; the memory..'s size.
console.info(Buffer.poolSize); /// 8192; a memory pool's size.

console.info(small_buffer.length); /// 3; the view's size.
console.info(small_buffer.buffer.byteLength); /// 8192; the memory pool's size.
console.info(Buffer.poolSize); /// 8192; a memory pool's size.

console.info(big_buffer.length); /// 4096; the view's size.
console.info(big_buffer.buffer.byteLength); /// 4096; the memory's size.
console.info(Buffer.poolSize); /// 8192; a memory pool's size.

3. So we need to extract the memory it “views.”

An ArrayBuffer is fixed in size, so we need to extract it out by making a copy of the part. To do this, we use Buffer's byteOffset property and length property, which are inherited from Uint8Array, and the ArrayBuffer.prototype.slice method, which makes a copy of a part of an ArrayBuffer. The slice()-ing method herein was inspired by @ZachB.

const test_buffer = Buffer.from(new ArrayBuffer(10));
const zero_sized_buffer = Buffer.allocUnsafe(0);
const small_buffer = Buffer.from([0xC0, 0xFF, 0xEE]);
const big_buffer = Buffer.allocUnsafe(Buffer.poolSize >>> 1);

function extract_arraybuffer(buf)
{
    // You may use the `byteLength` property instead of the `length` one.
    return buf.buffer.slice(buf.byteOffset, buf.byteOffset + buf.length);
}

// A copy -
const test_arraybuffer = extract_arraybuffer(test_buffer); // of the memory.
const zero_sized_arraybuffer = extract_arraybuffer(zero_sized_buffer); // of the... void.
const small_arraybuffer = extract_arraybuffer(small_buffer); // of the part of the memory.
const big_arraybuffer = extract_arraybuffer(big_buffer); // of the memory.

console.info(test_arraybuffer.byteLength); // 10
console.info(zero_sized_arraybuffer.byteLength); // 0
console.info(small_arraybuffer.byteLength); // 3
console.info(big_arraybuffer.byteLength); // 4096

4. Performance improvement

If you're to use the results as read-only, or it is okay to modify the input Buffers' contents, you can avoid unnecessary memory copying.

const test_buffer = Buffer.from(new ArrayBuffer(10));
const zero_sized_buffer = Buffer.allocUnsafe(0);
const small_buffer = Buffer.from([0xC0, 0xFF, 0xEE]);
const big_buffer = Buffer.allocUnsafe(Buffer.poolSize >>> 1);

function obtain_arraybuffer(buf)
{
    if(buf.length === buf.buffer.byteLength)
    {
        return buf.buffer;
    } // else:
    // You may use the `byteLength` property instead of the `length` one.
    return buf.subarray(0, buf.length);
}

// Its underlying `ArrayBuffer`.
const test_arraybuffer = obtain_arraybuffer(test_buffer);
// Just a zero-sized `ArrayBuffer`.
const zero_sized_arraybuffer = obtain_arraybuffer(zero_sized_buffer);
// A copy of the part of the memory.
const small_arraybuffer = obtain_arraybuffer(small_buffer);
// Its underlying `ArrayBuffer`.
const big_arraybuffer = obtain_arraybuffer(big_buffer);

console.info(test_arraybuffer.byteLength); // 10
console.info(zero_sized_arraybuffer.byteLength); // 0
console.info(small_arraybuffer.byteLength); // 3
console.info(big_arraybuffer.byteLength); // 4096

You can use the Set structure from ES6 to make your code faster and more readable:

// Create Set
this.items = new Set();

add(item) {
    this.items.add(item);

    // Set to array
    console.log([...this.items]);
}

you can use the weight value specified in the Google Fonts.

Wxruby is a great framework, simple and clean. Try it or use glade with ruby (the simpliest option)

Note that this problem usually occure for two reasons:

1-Port 80 is busy.

2-Port 443 is busy.

For number one as the others said, you can kill Skype and SQL Serever Reporter from

Windows Task Manager>"Services" Tab>"Services..." Button.

But if it dosen't worked, it's probably because of port 443, so try this one:

If you use VMware, go to

Windows Task Manager>"Services" Tab>"Services..." Button, and find "VMware Workstation Server" service, double click on it and press "Stop" button.

There is no need to stop other VMware's services.

Then again try to run Apache

One notable exception seems to be ALU mul vs FPU mul. Addition and subtraction seem trivially different.

A few points:

1) "DataBind()" is only for web apps (not windows apps).

2) Your code looks very 'JAVAish' (not a bad thing, just an observation).

Try this:

mnuActionLanguage.ComboBox.DataSource = languages;

If that doesn't work... then I'm assuming that your datasource is being stepped on somewhere else in the code.

var firstName = "John";
var id = 12;

ctx.Database.ExecuteSqlCommand(@"Update [User] SET FirstName = {0} WHERE Id = {1}"
, new object[]{ firstName, id });

This is so simple !!!

Image for knowing parameter reference

You can just do (a,). No need to use a function. (Note that the comma is necessary.)

Essentially, tuple(a) means to make a tuple of the contents of a, not a tuple consisting of just a itself. The "contents" of a string (what you get when you iterate over it) are its characters, which is why it is split into characters.

# Original code
df = pd.DataFrame({'a': [1, 2, 3, 'bad', 5],
                   'b': [0.1, 0.2, 0.3, 0.4, 0.5],
                   'item': ['a', 'b', 'c', 'd', 'e']})
df = df.set_index('item')

Convert to numeric using 'coerce' which fills bad values with 'nan'

a = pd.to_numeric(df.a, errors='coerce')

Use isna to return a boolean index:

idx = a.isna()

Apply that index to the data frame:

df[idx]

output

Returns the row with the bad data in it:

        a    b
item          
d     bad  0.4

<ul class="col col-double clearfix">
 <li class="col__item" ng-repeat="location in searchLocations">
   <label>
    <input type="checkbox" ng-click="onLocationSelectionClicked($event)" checklist-model="selectedAuctions.locations" checklist-value="location.code" checklist-change="auctionSelectionChanged()" id="{{location.code}}"> {{location.displayName}}
   </label>



$scope.onLocationSelectionClicked = function($event) {
      if($scope.limitSelectionCountTo &&         $scope.selectedAuctions.locations.length == $scope.limitSelectionCountTo) {
         $event.currentTarget.checked=false;
      }
   };

The DataTable.Clone() method works great when you want to create a completely new DataTable, but there might be cases where you would want to add the schema columns from one DataTable to another existing DataTable.

For example, if you've derived a new subclass from DataTable, and want to import schema information into it, you couldn't use Clone().

E.g.:

public class CoolNewTable : DataTable {
   public void FillFromReader(DbDataReader reader) {
       // We want to get the schema information (i.e. columns) from the 
       // DbDataReader and 
       // import it into *this* DataTable, NOT a new one.
       DataTable schema = reader.GetSchemaTable(); 
       //GetSchemaTable() returns a DataTable with the columns we want.

       ImportSchema(this, schema); // <--- how do we do this?
   }
}

The answer is just to create new DataColumns in the existing DataTable using the schema table's columns as templates.

I.e. the code for ImportSchema would be something like this:

void ImportSchema(DataTable dest, DataTable source) {
    foreach(var c in source.Columns)
        dest.Columns.Add(c);
}

or, if you're using Linq:

void ImportSchema(DataTable dest, DataTable source) {
    var cols = source.Columns.Cast<DataColumn>().ToArray();
    dest.Columns.AddRange(cols);
}

This was just one example of a situation where you might want to copy schema/columns from one DataTable into another one without using Clone() to create a completely new DataTable. I'm sure I've come across several others as well.

Basically this error comes when you have not specified a password, it means that you have an incorrect password listed in some option file.

Read this DOC on understanding how to assign and manage Passwords to accounts.

Also , Check if the permission on the folder /var/lib/mysql/mysql is 711 or not.

As @Seth Holladay @MinusFour commented, you are parsing an undefined variable.
Try adding an if condition before doing the parse.

if (typeof test1 !== 'undefined') { test2 = JSON.parse(test1); }

Note: This is just a check for undefined case. Any other parsing issues still need to be handled.

Solution 1: Framework blackboxing

Works great, minimal setup and no third parties.

According to Chrome's documentation:

What happens when you blackbox a script?

Exceptions thrown from library code will not pause (if Pause on exceptions is enabled), Stepping into/out/over bypasses the library code, Event listener breakpoints don't break in library code, The debugger will not pause on any breakpoints set in library code. The end result is you are debugging your application code instead of third party resources.

1. Pop open Chrome Developer Tools (F12 or ?+?+i), go to settings (upper right, or F1). Find a tab on the left called "Blackboxing"

2. This is where you put the RegEx pattern of the files you want Chrome to ignore while debugging. For example: jquery\..*\.js (glob pattern/human translation: jquery.*.js)
3. If you want to skip files with multiple patterns you can add them using the pipe character, |, like so: jquery\..*\.js|include\.postload\.js (which acts like an "or this pattern", so to speak. Or keep adding them with the "Add" button.
4. Now continue to Solution 3 described down below.

Bonus tip! I use Regex101 regularly (but there are many others: ) to quickly test my rusty regex patterns and find out where I'm wrong with the step-by-step regex debugger. If you are not yet "fluent" in Regular Expressions I recommend you start using sites that help you write and visualize them such as http://buildregex.com/ and https://www.debuggex.com/

You can also use the context menu when working in the Sources panel. When viewing a file, you can right-click in the editor and choose Blackbox Script. This will add the file to the list in the Settings panel:

Solution 2: Visual Event

It's an excellent tool to have:

Visual Event is an open-source Javascript bookmarklet which provides debugging information about events that have been attached to DOM elements. Visual Event shows:

• Which elements have events attached to them
• The type of events attached to an element
• The code that will be run with the event is triggered
• The source file and line number for where the attached function was defined (Webkit browsers and Opera only)

Solution 3: Debugging

You can pause the code when you click somewhere in the page, or when the DOM is modified... and other kinds of JS breakpoints that will be useful to know. You should apply blackboxing here to avoid a nightmare.

In this instance, I want to know what exactly goes on when I click the button.

1. Open Dev Tools -> Sources tab, and on the right find Event Listener Breakpoints:

   

2. Expand Mouse and select click

3. Now click the element (execution should pause), and you are now debugging the code. You can go through all code pressing F11 (which is Step in). Or go back a few jumps in the stack. There can be a ton of jumps

Solution 4: Fishing keywords

With Dev Tools activated, you can search the whole codebase (all code in all files) with ?+?+F or:

and searching #envio or whatever the tag/class/id you think starts the party and you may get somewhere faster than anticipated.

Be aware sometimes there's not only an img but lots of elements stacked, and you may not know which one triggers the code.

If this is a bit out of your knowledge, take a look at Chrome's tutorial on debugging.

For a default export we do not use { } when we import.

For example,

File player.js

export default vx;

File index.js

import vx from './player';

File index.js

File player.js

If we want to import everything that we export then we use *:

If you're only replacing single characters, you should use strtr()

If you want the entire command line of your java process, you can use: JvmArguments.java (uses a combination of JNA + /proc to cover most unix implementations)

Swift 5
This handy extension handles few more cases than previous answers. These cases are VC(view controller) is the root VC of app window, VC is added as child to parent VC. It tries to return true only if the viewcontroller is modally presented.

extension UIViewController {
    /**
      returns true only if the viewcontroller is presented.
    */
    var isModal: Bool {
        if let index = navigationController?.viewControllers.firstIndex(of: self), index > 0 {
            return false
        } else if presentingViewController != nil {
            if let parent = parent, !(parent is UINavigationController || parent is UITabBarController) {
                return false
            }
            return true
        } else if let navController = navigationController, navController.presentingViewController?.presentedViewController == navController {
            return true
        } else if tabBarController?.presentingViewController is UITabBarController {
            return true
        }
        return false
    }
}

    document.addEventListener("mousedown", handleClickOutside);
    return () => {
      // Unbind the event listener on clean up
      document.removeEventListener("mousedown", handleClickOutside);
    };
  });

  return (
    <div ref={ref}>
        ...
    </div>
  );
}

A likely possibility is that your browser reaches your web service through a proxy, and SoapUI is not configured to use that proxy. For example, I work in a corporate environment and while my IE and FireFox can access external websites, my SoapUI can only access internal web services.

The easy solution is to just open the WSDL in a browser, save it to a .xml file, and base your SoapUI project on that. This won't work if your WSDL relies on external XSDs that it can't get to, however.

You can use count() function, which has however a different behaviour depending on the version of dplyr:

• dplyr 0.7.1: returns an ungrouped table: you need to group again by am

• dplyr < 0.7.1: returns a grouped table, so no need to group again, although you might want to ungroup() for later manipulations

dplyr 0.7.1

mtcars %>%
  count(am, gear) %>%
  group_by(am) %>%
  mutate(freq = n / sum(n))

dplyr < 0.7.1

mtcars %>%
  count(am, gear) %>%
  mutate(freq = n / sum(n))

This results into a grouped table, if you want to use it for further analysis, it might be useful to remove the grouped attribute with ungroup().

Can you use R to replace MATLAB?

Yes.

I used MATLAB for years but switched primarily to R in the last 3 years. At this point, they have much more in common than not. It partially depends on your field and use-case. And as Spencer Graves said previously, it also depends on which "church you happen to frequent". It's best if you look at the MATLAB toolkit vs. CRAN for a specific task before you decide.

A similar question asked on R-Help a few years ago and again more recently. David Hiebeler (at the University of Maine) maintains an extensive R/MATLAB comparison, and is the best reference on the subject. You can also review this comparison of basic functions.

Here are some of the things that I've observed in the past, none of which should be deal-breakers.

• Generally, MATLAB has a better programming environment (e.g. better documentation, better debuggers, better object browser) and is "easier" to use (you can use MATLAB without doing any programming if you want). Simulink allows you to visually program by connecting blocks in graphs. REvolution R is addressing some of these differences by providing a better IDE with improved debugging, but it's still a step behind.
• MATLAB is a little faster with the normal configuration (see this benchmark for an example), although there are things that can be done to improve R performance if that becomes an issue.
• Since it's commercial, it also arguably has more "products" (in the sense of integrated add-ons) and support (but you pay for it). See the product list. For instance, it has things like the MATLAB compiler which creates executable MATLAB programs that can be deployed.
• So far as packages/toolkits are concerned, MATLAB has much more support for the physical sciences while R is stronger for statistics, which is not to say that the other can't perform these tasks. And they can both be easily extended.

So, if ease-of-use isn't a primary concern (and there's no other business reason to avoid using an open-source tool), then I think that there's a real case to be made for using R. It has a very strong community around it (the R mailing lists are amazing), is rapidly developing (see CRAN), and it's free (which isn't a small issue!).

Edit: I would just add one further point to this: the book "Functional Data Analysis with R and MATLAB" includes a chapter on the "Essential Comparisons of the Matlab and R Languages". This covers some important syntax differences (such as the interpretation of a dot, or the meaning of square brackets []). The book itself is well worth reading for anyone interested in functional programming (in either language).

In your /etc/nginx/nginx.conf file you have:

include /etc/nginx/site-enabled/*;

And probably the path you are using is:

/etc/nginx/sites-enabled/default

Notice the missing s in site.

Maybe you can try the following without XPath

from simplified_scrapy.simplified_doc import SimplifiedDoc 
html = '''
<html>
<body>
<div>
    <h1>Example Domain</h1>
    <p>This domain is for use in illustrative examples in documents. You may use this
    domain in literature without prior coordination or asking for permission.</p>
    <p><a href="https://www.iana.org/domains/example">More information...</a></p>
</div>
</body>
</html>
'''
# What XPath can do, so can it
doc = SimplifiedDoc(html)
# The result is the same as doc.getElementByTag('body').getElementByTag('div').getElementByTag('h1').text
print (doc.body.div.h1.text)
print (doc.div.h1.text)
print (doc.h1.text) # Shorter paths will be faster
print (doc.div.getChildren())
print (doc.div.getChildren('p'))

I personally use prepared statements.

Why is it important?

Well it's important because of security. It's very easy to do an SQL injection on someone who use variables in the query.

Instead of using this code:

$query = "SELECT username,userid FROM user WHERE username = 'admin' ";
$result=$conn->query($query);

You should use this

$stmt = $this->db->query("SELECT * FROM users WHERE username = ? AND password = ?");
$stmt->bind_param("ss", $username, $password); //You need the variables to do something as well.
$stmt->execute();

Learn more about prepared statements on:

http://php.net/manual/en/mysqli.quickstart.prepared-statements.php MySQLI

http://php.net/manual/en/pdo.prepared-statements.php PDO

If you using Anaconda3

Just put

conda install -c conda-forge matplotlib

Recently we had a similar problem and had to solve it in a different way. We had to merge two branches up to two commits, which were not the heads of either branches:

branch A: A1 -> A2 -> A3 -> A4
branch B: B1 -> B2 -> B3 -> B4
branch C: C1 -> A2 -> B3 -> C2

For example, we had to merge branch A up to A2 and branch B up to B3. But branch C had cherry-picks from A and B. When using the SHA of A2 and B3 it looked like there was confusion because of the local branch C which had the same SHA.

To avoid any kind of ambiguity we removed branch C locally, and then created a branch AA starting from commit A2:

git co A
git co SHA-of-A2
git co -b AA

Then we created a branch BB from commit B3:

git co B
git co SHA-of-B3
git co -b BB

At that point we merged the two branches AA and BB. By removing branch C and then referencing the branches instead of the commits it worked.

It's not clear to me how much of this was superstition or what actually made it work, but this "long approach" may be helpful.

Both these will give you the first child node:

console.log(parentElement.firstChild); // or
console.log(parentElement.childNodes[0]);

If you need the first child that is an element node then use:

console.log(parentElement.children[0]);

Edit

Ah, I see your problem now; parentElement is an array.

If you know that getElementsByClassName will only return one result, which it seems you do, you should use [0] to dearray (yes, I made that word up) the element:

var parentElement = document.getElementsByClassName("uniqueClassName")[0];

The accepted answers animation does not work on Safari, I've updated it using translate instead of padding-left which makes for a smoother, bulletproof animation.

Wow, after few attempts I finally figured out how to deal with my text edits in vbs. The code works perfectly, it gives me the result I was expecting. Maybe it's not the best way to do this, but it does its job. Here's the code:

Option Explicit

Dim StdIn:  Set StdIn = WScript.StdIn
Dim StdOut: Set StdOut = WScript


Main()

Sub Main()

Dim objFSO, filepath, objInputFile, tmpStr, ForWriting, ForReading, count, text, objOutputFile, index, TSGlobalPath, foundFirstMatch
Set objFSO = CreateObject("Scripting.FileSystemObject")
TSGlobalPath = "C:\VBS\TestSuiteGlobal\Test suite Dispatch Decimal - Global.txt"
ForReading = 1
ForWriting = 2
Set objInputFile = objFSO.OpenTextFile(TSGlobalPath, ForReading, False)
count = 7
text=""
foundFirstMatch = false

Do until objInputFile.AtEndOfStream
    tmpStr = objInputFile.ReadLine
    If foundStrMatch(tmpStr)=true Then
        If foundFirstMatch = false Then
            index = getIndex(tmpStr)
            foundFirstMatch = true
            text = text & vbCrLf & textSubstitution(tmpStr,index,"true")
        End If
        If index = getIndex(tmpStr) Then
            text = text & vbCrLf & textSubstitution(tmpStr,index,"false")
        ElseIf index < getIndex(tmpStr) Then
            index = getIndex(tmpStr)
            text = text & vbCrLf & textSubstitution(tmpStr,index,"true")
        End If
    Else
        text = text & vbCrLf & textSubstitution(tmpStr,index,"false")
    End If
Loop
Set objOutputFile = objFSO.CreateTextFile("C:\VBS\NuovaProva.txt", ForWriting, true)
objOutputFile.Write(text)
End Sub


Function textSubstitution(tmpStr,index,foundMatch)
Dim strToAdd
strToAdd = "<tr><td><a href=" & chr(34) & "../../Logs/CF5.0_Features/Beginning_of_CF5.0_Features_TC" & CStr(index) & ".html" & chr(34) & ">Beginning_of_CF5.0_Features_TC" & CStr(index) & "</a></td></tr>"
If foundMatch = "false" Then
    textSubstitution = tmpStr
ElseIf foundMatch = "true" Then
    textSubstitution = strToAdd & vbCrLf & tmpStr
End If
End Function


Function getIndex(tmpStr)
Dim substrToFind, charAtPos, char1, char2
substrToFind = "<tr><td><a href=" & chr(34) & "../Test case "
charAtPos = len(substrToFind) + 1
char1 = Mid(tmpStr, charAtPos, 1)
char2 = Mid(tmpStr, charAtPos+1, 1)
If IsNumeric(char2) Then
    getIndex = CInt(char1 & char2)
Else
    getIndex = CInt(char1)
End If
End Function

Function foundStrMatch(tmpStr)
Dim substrToFind
substrToFind = "<tr><td><a href=" & chr(34) & "../Test case "
If InStr(tmpStr, substrToFind) > 0 Then
    foundStrMatch = true
Else
    foundStrMatch = false
End If
End Function

This is the original txt file

1. Compile your application with -g, then you'll have debug symbols in the binary file.

2. Use gdb to open the gdb console.

3. Use file and pass it your application's binary file in the console.

4. Use run and pass in any arguments your application needs to start.

5. Do something to cause a Segmentation Fault.

6. Type bt in the gdb console to get a stack trace of the Segmentation Fault.

Essentially:

history.pushState('data', '', 'http://your-domain/path');

You can manipulate the history object to make this work.

It only works on the same domain, but since you're satisfied with using the hash tag approach, that shouldn't matter.

Obviously would need to be cross-browser tested, but since that was posted on the Opera forum I'm safe to assume it would work in Opera, and I just tested it in Chrome and it worked fine.

the World Wide Web Consortium HTML Validator is great at catching HTML errors.

The proper function is int fileno(FILE *stream). It can be found in <stdio.h>, and is a POSIX standard but not standard C.

Try this if this works for you

android:background="@drawable/drop_shadow"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:paddingLeft="3dp"
        android:paddingTop="3dp"
        android:paddingRight="4dp"
        android:paddingBottom="5dp"

public static class Webdriver
{        
    public static void ExecuteJavaScript(string scripts)
    {
        IJavaScriptExecutor js = (IJavaScriptExecutor)driver;
        js.ExecuteScript(scripts);
    }

    public static T ExecuteJavaScript<T>(string scripts)
    {
        IJavaScriptExecutor js = (IJavaScriptExecutor)driver;
        return (T)js.ExecuteScript(scripts);
    }
}

In your code you can then do

string test = Webdriver.ExecuteJavaScript<string>(" return 'hello World'; ");
int test = Webdriver.ExecuteJavaScript<int>(" return 3; ");

How about using the ExecutorService.shutDownNow() method as described in http://docs.oracle.com/javase/7/docs/api/java/util/concurrent/ExecutorService.html? It seems to be the simplest solution.

Node.js is built upon libuv, a cross-platform library that abstracts apis/syscalls for asynchronous (non-blocking) input/output provided by the supported OSes (Unix, OS X and Windows at least).

Asynchronous IO

In this programming model open/read/write operation on devices and resources (sockets, filesystem, etc.) managed by the file-system don't block the calling thread (as in the typical synchronous c-like model) and just mark the process (in kernel/OS level data structure) to be notified when new data or events are available. In case of a web-server-like app, the process is then responsible to figure out which request/context the notified event belongs to and proceed processing the request from there. Note that this will necessarily mean you'll be on a different stack frame from the one that originated the request to the OS as the latter had to yield to a process' dispatcher in order for a single threaded process to handle new events.

The problem with the model I described is that it's not familiar and hard to reason about for the programmer as it's non-sequential in nature. "You need to make request in function A and handle the result in a different function where your locals from A are usually not available."

Node's model (Continuation Passing Style and Event Loop)

Node tackles the problem leveraging javascript's language features to make this model a little more synchronous-looking by inducing the programmer to employ a certain programming style. Every function that requests IO has a signature like function (... parameters ..., callback) and needs to be given a callback that will be invoked when the requested operation is completed (keep in mind that most of the time is spent waiting for the OS to signal the completion - time that can be spent doing other work). Javascript's support for closures allows you to use variables you've defined in the outer (calling) function inside the body of the callback - this allows to keep state between different functions that will be invoked by the node runtime independently. See also Continuation Passing Style.

Moreover, after invoking a function spawning an IO operation the calling function will usually return control to node's event loop. This loop will invoke the next callback or function that was scheduled for execution (most likely because the corresponding event was notified by the OS) - this allows the concurrent processing of multiple requests.

You can think of node's event loop as somewhat similar to the kernel's dispatcher: the kernel would schedule for execution a blocked thread once its pending IO is completed while node will schedule a callback when the corresponding event has occured.

Highly concurrent, no parallelism

As a final remark, the phrase "everything runs in parallel except your code" does a decent job of capturing the point that node allows your code to handle requests from hundreds of thousands open socket with a single thread concurrently by multiplexing and sequencing all your js logic in a single stream of execution (even though saying "everything runs in parallel" is probably not correct here - see Concurrency vs Parallelism - What is the difference?). This works pretty well for webapp servers as most of the time is actually spent on waiting for network or disk (database / sockets) and the logic is not really CPU intensive - that is to say: this works well for IO-bound workloads.

If you are in local branch, could rename the branch "Feature/Name" to "feature/Name"

git -m feature/Name

if you have problems to make a git push make a checkout in other branch (ex develop) and return to renamed branch

git checkout feature/Name

and try again your git push

Just wanted to throw out a real use case that demonstrates idempotence. In JavaScript, say you are defining a bunch of model classes (as in MVC model). The way this is often implemented is functionally equivalent to something like this (basic example):

function model(name) {
  function Model() {
    this.name = name;
  }

  return Model;
}

You could then define new classes like this:

var User = model('user');
var Article = model('article');

But if you were to try to get the User class via model('user'), from somewhere else in the code, it would fail:

var User = model('user');
// ... then somewhere else in the code (in a different scope)
var User = model('user');

Those two User constructors would be different. That is,

model('user') !== model('user');

To make it idempotent, you would just add some sort of caching mechanism, like this:

var collection = {};

function model(name) {
  if (collection[name])
    return collection[name];

  function Model() {
    this.name = name;
  }

  collection[name] = Model;
  return Model;
}

By adding caching, every time you did model('user') it will be the same object, and so it's idempotent. So:

model('user') === model('user');

#include <iostream>

int main ()
{
    using namespace std;
    int arr[] = {2, 7, 1, 111};
    auto array_length = end(arr) - begin(arr);
    cout << "Length of array: " << array_length << endl;
}

Can someone help me with the exact syntax?

It's a three-step process, and it involves modifying the openssl.cnf file. You might be able to do it with only command line options, but I don't do it that way.

Find your openssl.cnf file. It is likely located in /usr/lib/ssl/openssl.cnf:

$ find /usr/lib -name openssl.cnf
/usr/lib/openssl.cnf
/usr/lib/openssh/openssl.cnf
/usr/lib/ssl/openssl.cnf

On my Debian system, /usr/lib/ssl/openssl.cnf is used by the built-in openssl program. On recent Debian systems it is located at /etc/ssl/openssl.cnf

You can determine which openssl.cnf is being used by adding a spurious XXX to the file and see if openssl chokes.

First, modify the req parameters. Add an alternate_names section to openssl.cnf with the names you want to use. There are no existing alternate_names sections, so it does not matter where you add it.

[ alternate_names ]

DNS.1        = example.com
DNS.2        = www.example.com
DNS.3        = mail.example.com
DNS.4        = ftp.example.com

Next, add the following to the existing [ v3_ca ] section. Search for the exact string [ v3_ca ]:

subjectAltName      = @alternate_names

You might change keyUsage to the following under [ v3_ca ]:

keyUsage = digitalSignature, keyEncipherment

digitalSignature and keyEncipherment are standard fare for a server certificate. Don't worry about nonRepudiation. It's a useless bit thought up by computer science guys/gals who wanted to be lawyers. It means nothing in the legal world.

In the end, the IETF (RFC 5280), browsers and CAs run fast and loose, so it probably does not matter what key usage you provide.

Second, modify the signing parameters. Find this line under the CA_default section:

# Extension copying option: use with caution.
# copy_extensions = copy

And change it to:

# Extension copying option: use with caution.
copy_extensions = copy

This ensures the SANs are copied into the certificate. The other ways to copy the DNS names are broken.

Third, generate your self-signed certificate:

$ openssl genrsa -out private.key 3072
$ openssl req -new -x509 -key private.key -sha256 -out certificate.pem -days 730
You are about to be asked to enter information that will be incorporated
into your certificate request.
What you are about to enter is what is called a Distinguished Name or a DN.
...

Finally, examine the certificate:

$ openssl x509 -in certificate.pem -text -noout

Flyway library is really good for this:

    Flyway flyway = new Flyway();
    flyway.setDataSource(dbConfig.getUrl(), dbConfig.getUsername(), dbConfig.getPassword());
    flyway.setLocations("classpath:db/scripts");
    flyway.clean();
    flyway.migrate();

This scans the locations for scripts and runs them in order. Scripts can be versioned with V01__name.sql so if just the migrate is called then only those not already run will be run. Uses a table called 'schema_version' to keep track of things. But can do other things too, see the docs: flyway.

The clean call isn't required, but useful to start from a clean DB. Also, be aware of the location (default is "classpath:db/migration"), there is no space after the ':', that one caught me out.

very old thread but .. i was lookin for an "easier"... a smaller code

i honestly dont understand any of the answers above :D - i´m a noob

but this should do the job. (for smaller sheets)

Set objExcel = CreateObject("Excel.Application")
objExcel.Workbooks.Add

reads every cell in col 1 from bottom up and stops at first empty cell

intRow = 1
Do until objExcel.Cells(intRow, 1).Value = ""
   intRow = intRow + 1
Loop

then you can write your info like this

objExcel.Cells(intRow, 1).Value = "first emtpy row, col 1"
objExcel.Cells(intRow, 2).Value = "first emtpy row, col 2"

etc...

and then i recognize its an vba thread ... lol

You can use the standard JSON object, available in Javascript:

var a: any = {};
a.x = 10;
a.y='hello';
var jsonString = JSON.stringify(a);

I wrote this procedure inspired by Cherian's answer. The difference is that in my version the user name is an argument of the procedure ( and not hard coded ) . I'm also doing a much necessary FLUSH PRIVILEGES after dropping the user.

DROP PROCEDURE IF EXISTS DropUserIfExists;
DELIMITER $$
CREATE PROCEDURE DropUserIfExists(MyUserName VARCHAR(100))
BEGIN
  DECLARE foo BIGINT DEFAULT 0 ;
  SELECT COUNT(*)
  INTO foo
    FROM mysql.user
      WHERE User = MyUserName ;
   IF foo > 0 THEN
         SET @A = (SELECT Result FROM (SELECT GROUP_CONCAT("DROP USER"," ",MyUserName,"@'%'") AS Result) AS Q LIMIT 1);
         PREPARE STMT FROM @A;
         EXECUTE STMT;
         FLUSH PRIVILEGES;
   END IF;
END ;$$
DELIMITER ;

I also posted this code on the CodeReview website ( https://codereview.stackexchange.com/questions/15716/mysql-drop-user-if-exists )

In eclipse try to go to file properties (Alt+Enter) and change the Resource → 'Text File encoding' → Other to UTF-8. Reopen the file and check there will be junk character somewhere in the string/file. Remove it. Save the file.

Change the encoding Resource → 'Text File encoding' back to Default.

Compile and deploy the code.

You can bootstrap multiple angular applications, but:

1) You need to manually bootstrap them

2) You should not use "document" as the root, but the node where the angular interface is contained to:

var todoRootNode = jQuery('[ng-controller=TodoController]');
angular.bootstrap(todoRootNode, ['TodoApp']);

This would be safe.

If you want it really easy and a joy to automate, check out Chocolatey.org/install and you can basically copy and paste these commands and tweak it based on what versions of VC++ you need.

This command is taken from https://chocolatey.org/install

Set-ExecutionPolicy Bypass -Scope Process -Force; [System.Net.ServicePointManager]::SecurityProtocol = [System.Net.ServicePointManager]::SecurityProtocol -bor 3072; iex ((New-Object System.Net.WebClient).DownloadString('https://chocolatey.org/install.ps1'))

Once you have chocolatey installed you can either close and reopen your Powershell terminal or run this command:

Import-Module "$env:ChocolateyInstall\helpers\chocolateyInstaller.psm1" ; Update-SessionEnvironment

Now you can use Chocolatey to install Python (latest version of 3.x is default).

choco install python

# This next command installs the latest VisualStudio installer that lets you get specific versions of the build
# Microsoft has replaced the 2015 and 2017 installer links with this one, and we can still use it to install the 2015 and 2017 components

choco install visualstudio2019buildtools --package-parameters "--add Microsoft.VisualStudio.Component.VC.140 --passive --locale en-US --add Microsoft.VisualStudio.Component.Windows10SDK.$($PSVersionTable.BuildVersion.Build) --no-includeRecommended" -y --timeout 0

# Usually need the "unlimited" timeout aka "0" because Visual Studio Installer takes forever

# Tool portion

Once you have this installed, you should reboot. I've occasionally had things work without a reboot, but your pip install commands will work best if you reboot first.

Now you can pip install pipenv or pip install complex-package and should be good to go.

While inserting multiple rows with a single INSERT statement is generally faster, it leads to a more complicated and often unsafe code. Below I present the best practices when it comes to inserting multiple records in one go using PHP.

To insert multiple new rows into the database at the same time, one needs to follow the following 3 steps:

1. Start transaction (disable autocommit mode)
2. Prepare INSERT statement
3. Execute it multiple times

Using database transactions ensures that the data is saved in one piece and significantly improves performance.

How to properly insert multiple rows using PDO

PDO is the most common choice of database extension in PHP and inserting multiple records with PDO is quite simple.

$pdo = new \PDO("mysql:host=localhost;dbname=test;charset=utf8mb4", 'user', 'password', [
    \PDO::ATTR_ERRMODE => \PDO::ERRMODE_EXCEPTION,
    \PDO::ATTR_EMULATE_PREPARES => false
]);

// Start transaction
$pdo->beginTransaction();

// Prepare statement
$stmt = $pdo->prepare('INSERT 
    INTO `pxlot` (realname,email,address,phone,status,regtime,ip) 
    VALUES (?,?,?,?,?,?,?)');

// Perform execute() inside a loop
// Sample data coming from a fictitious data set, but the data can come from anywhere
foreach ($dataSet as $data) {
    // All seven parameters are passed into the execute() in a form of an array
    $stmt->execute([$data['name'], $data['email'], $data['address'], getPhoneNo($data['name']), '0', $data['regtime'], $data['ip']]);
}

// Commit the data into the database
$pdo->commit();

How to properly insert multiple rows using mysqli

The mysqli extension is a little bit more cumbersome to use but operates on very similar principles. The function names are different and take slightly different parameters.

mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT);
$mysqli = new \mysqli('localhost', 'user', 'password', 'database');
$mysqli->set_charset('utf8mb4');

// Start transaction
$mysqli->begin_transaction();

// Prepare statement
$stmt = $mysqli->prepare('INSERT 
    INTO `pxlot` (realname,email,address,phone,status,regtime,ip) 
    VALUES (?,?,?,?,?,?,?)');

// Perform execute() inside a loop
// Sample data coming from a fictitious data set, but the data can come from anywhere
foreach ($dataSet as $data) {
    // mysqli doesn't accept bind in execute yet, so we have to bind the data first
    // The first argument is a list of letters denoting types of parameters. It's best to use 's' for all unless you need a specific type
    // bind_param doesn't accept an array so we need to unpack it first using '...'
    $stmt->bind_param('sssssss', ...[$data['name'], $data['email'], $data['address'], getPhoneNo($data['name']), '0', $data['regtime'], $data['ip']]);
    $stmt->execute();
}

// Commit the data into the database
$mysqli->commit();

Performance

Both extensions offer the ability to use transactions. Executing prepared statement with transactions greatly improves performance, but it's still not as good as a single SQL query. However, the difference is so negligible that for the sake of conciseness and clean code it is perfectly acceptable to execute prepared statements multiple times. If you need a faster option to insert many records into the database at once, then chances are that PHP is not the right tool.

Obligatory jQuery solution. Finds and sets the title attribute to foo. Note this selects a single element since I'm doing it by id, but you could easily set the same attribute on a collection by changing the selector.

$('#element').attr( 'title', 'foo' );

Open pgAdmin and go to Properties for specific database. Find OID and then open directory

<POSTGRESQL_DIRECTORY>/data/base/<OID>

There should be your DB files.

First check for an error (N/A value) and then try the comparisation against cvErr(). You are comparing two different things, a value and an error. This may work, but not always. Simply casting the expression to an error may result in similar problems because it is not a real error only the value of an error which depends on the expression.

If IsError(ActiveWorkbook.Sheets("Publish").Range("G4").offset(offsetCount, 0).Value) Then
  If (ActiveWorkbook.Sheets("Publish").Range("G4").offset(offsetCount, 0).Value <> CVErr(xlErrNA)) Then
    'do something
  End If
End If

This worked for me:

step 1) Removing the interpreter, auto configuring it again

step 2) Window - Preferences - PyDev - Interpreters - Python Interpreter Go to the Forced builtins tab Click on New... Type the name of the module (curses in my case) and click OK

step 3) Right click in the project explorer on whichever module is giving errors. Go to PyDev->Code analysis.

I created a generic solution out of the existing answers which can be reused for any table:

CREATE OR REPLACE FUNCTION create_if_not_exists (table_name text, create_stmt text)
RETURNS text AS
$_$
BEGIN

IF EXISTS (
    SELECT *
    FROM   pg_catalog.pg_tables 
    WHERE    tablename  = table_name
    ) THEN
   RETURN 'TABLE ' || '''' || table_name || '''' || ' ALREADY EXISTS';
ELSE
   EXECUTE create_stmt;
   RETURN 'CREATED';
END IF;

END;
$_$ LANGUAGE plpgsql;

Usage:

select create_if_not_exists('my_table', 'CREATE TABLE my_table (id integer NOT NULL);');

It could be simplified further to take just one parameter if one would extract the table name out of the query parameter. Also I left out the schemas.

Ok, so here was my process:

keytool -list -v -keystore permanent.jks - got me the alias.

keytool -export -alias alias_name -file certificate_name -keystore permanent.jks - got me the certificate to import.

Then I could import it with the keytool:

keytool -import -alias alias_name -file certificate_name -keystore keystore location

As @Christian Bongiorno says the alias can't already exist in your keystore.

I put together a little test here:

\documentclass[10pt,twocolumn]{article}

\title{Article Title}
\author{

    school\\
    email@edu

\date{\today}

\begin{document}

\maketitle

\begin{abstract}
\ldots
\end{abstract}

\section{Introduction}
\ldots

\end{document}

Things to note, the title, author and date fields are declared before \begin{document}. Also, the multicol package is likely unnecessary in this case since you have declared twocolumn in the document class.

This example puts all four authors on the same line, but if your authors have longer names, departments or emails, this might cause it to flow over onto another line. You might be able to change the font sizes around a little bit to make things fit. This could be done by doing something like {\small First Author}. Here's a more detailed article on \LaTeX font sizes:

https://engineering.purdue.edu/ECN/Support/KB/Docs/LaTeXChangingTheFont

To italicize you can use {\it First Name} or \textit{First Name}.

Be careful though, if the document is meant for publication often times journals or conference proceedings have their own formatting guidelines so font size trickery might not be allowed.

If you are using JetBrains Idea IDE (and derivatives) you can select several lines, right click for the context menu, then Git -> Show history for selection. You will see list of commits which were affecting the selected lines:

If you want get output only when php fail:

php -r 'echo file_get_contents(http://www.example.com/cronit.php);'

This way you receive an email from cronjob only when the script fails and not whenever the php is called.

If using another library is an option, the following may be easier:

package for_so;

import java.io.File;

import rasmus_torkel.xml_basic.read.TagNode;
import rasmus_torkel.xml_basic.read.XmlReadOptions;
import rasmus_torkel.xml_basic.read.impl.XmlReader;

public class Q7704827_SimpleRead
{
    public static void
    main(String[] args)
    {
        String fileName = args[0];

        TagNode emailNode = XmlReader.xmlFileToRoot(new File(fileName), "EmailSettings", XmlReadOptions.DEFAULT);
        String recipient = emailNode.nextTextFieldE("recipient");
        String sender = emailNode.nextTextFieldE("sender");
        String subject = emailNode.nextTextFieldE("subject");
        String description = emailNode.nextTextFieldE("description");
        emailNode.verifyNoMoreChildren();

        System.out.println("recipient =  " + recipient);
        System.out.println("sender =     " + sender);
        System.out.println("subject =    " + subject);
        System.out.println("desciption = " + description);
    }
}

The library and its documentation are at rasmustorkel.com

You need, for example:

<input type="text" name="idtest" value="<?php echo $idtest; ?>" />

The echo function is what actually outputs the value of the variable.

Use attribute queryParamsHandling: 'merge' while changing the url.

this.router.navigate([], {
        queryParams: this.queryParams,
        queryParamsHandling: 'merge',
        replaceUrl: true,
});

Use pd.concat to merge a list of DataFrame into a single big DataFrame.

appended_data = []
for infile in glob.glob("*.xlsx"):
    data = pandas.read_excel(infile)
    # store DataFrame in list
    appended_data.append(data)
# see pd.concat documentation for more info
appended_data = pd.concat(appended_data)
# write DataFrame to an excel sheet 
appended_data.to_excel('appended.xlsx')

Example example;

Here example is an object on the stack.

Example* example=new Example();

This could be broken into:

Example* example;
....
example=new Example();

Here the first statement creates a variable example which is a "pointer to Example". When the constructor is called, memory is allocated for it on the heap (dynamic allocation). It is the programmer's responsibility to free this memory when it is no longer needed. (C++ does not have garbage collection like java).

None of the current answers worked for me. I'm using Bootstrap 3.

I liked what Rob Vermeer was doing and started from his response.

For a fade in and then fade out effect, I just used wrote the following function and used jQuery:

Html on my page to add the alert(s) to:

        <div class="alert-messages text-center">
        </div>

Javascript function to show and dismiss the alert.

function showAndDismissAlert(type, message) {
    var htmlAlert = '<div class="alert alert-' + type + '">' + message + '</div>';

    // Prepend so that alert is on top, could also append if we want new alerts to show below instead of on top.
    $(".alert-messages").prepend(htmlAlert);

    // Since we are prepending, take the first alert and tell it to fade in and then fade out.
    // Note: if we were appending, then should use last() instead of first()
    $(".alert-messages .alert").first().hide().fadeIn(200).delay(2000).fadeOut(1000, function () { $(this).remove(); });
}

Then, to show and dismiss the alert, just call the function like this:

    showAndDismissAlert('success', 'Saved Successfully!');
    showAndDismissAlert('danger', 'Error Encountered');
    showAndDismissAlert('info', 'Message Received');

As a side note, I styled the div.alert-messages fixed on top:

    <style>
    div.alert-messages {
        position: fixed;
        top: 50px;
        left: 25%;
        right: 25%;
        z-index: 7000;
    }
    </style>

First, it usually does not matter that much in practice. Most hash functions are "good enough".

But if you really care, you should know that it is a research subject by itself. There are thousand of papers about that. You can still get a PhD today by studying & designing hashing algorithms.

Your second hash function might be slightly better, because it probably should separate the string "ab" from the string "ba". On the other hand, it is probably less quick than the first hash function. It may, or may not, be relevant for your application.

I'll guess that hash functions used for genome strings are quite different than those used to hash family names in telephone databases. Perhaps even some string hash functions are better suited for German, than for English or French words.

Many software libraries give you good enough hash functions, e.g. Qt has qhash, and C++11 has std::hash in <functional>, Glib has several hash functions in C, and POCO has some hash function.

I quite often have hashing functions involving primes (see Bézout's identity) and xor, like e.g.

#define A 54059 /* a prime */
#define B 76963 /* another prime */
#define C 86969 /* yet another prime */
#define FIRSTH 37 /* also prime */
unsigned hash_str(const char* s)
{
   unsigned h = FIRSTH;
   while (*s) {
     h = (h * A) ^ (s[0] * B);
     s++;
   }
   return h; // or return h % C;
}

But I don't claim to be an hash expert. Of course, the values of A, B, C, FIRSTH should preferably be primes, but you could have chosen other prime numbers.

Look at some MD5 implementation to get a feeling of what hash functions can be.

Most good books on algorithmics have at least a whole chapter dedicated to hashing. Start with wikipages on hash function & hash table.

Style rules can be attached using:

• External Files
• In-page Style Tags
• Inline Style Attribute

Generally, I prefer to use linked style sheets because they:

• can be cached by browsers for performance; and
• are a lot easier to maintain for a development perspective.

However, your question is asking specifically about the style tag versus inline styles. Prefer to use the style tag, in this case, because it:

• provides a clear separation of markup from styling;
• produces cleaner HTML markup; and
• is more efficient with selectors to apply rules to multiple elements on a page improving management as well as making your page size smaller.

Inline elements only affect their respective element.

An important difference between the style tag and the inline attribute is specificity. Specificity determines when one style overrides another. Generally, inline styles have a higher specificity.

Read CSS: Specificity Wars for an entertaining look at this subject.

I hope that helps!

var nvc = new List<KeyValuePair<string, string>>();
nvc.Add(new KeyValuePair<string, string>("Input1", "TEST2"));

Google Chrome provides a built-in debugging tool called "Chrome DevTools" out of the box, which includes a handy feature that can evaluate or validate XPath/CSS selectors without any third party extensions.

This can be done by two approaches:

Use the search function inside Elements panel to evaluate XPath/CSS selectors and highlight matching nodes in the DOM. Execute tokens $x("some_xpath") or $$("css-selectors") in Console panel, which will both evaluate and validate.

From Elements panel

1. Press F12 to open up Chrome DevTools.

2. Elements panel should be opened by default.

3. Press Ctrl + F to enable DOM searching in the panel.

4. Type in XPath or CSS selectors to evaluate.

5. If there are matched elements, they will be highlighted in DOM. However, if there are matching strings inside DOM, they will be considered as valid results as well. For example, CSS selector header should match everything (inline CSS, scripts etc.) that contains the word header, instead of match only elements.

From Console panel

1. Press F12 to open up Chrome DevTools.

2. Switch to Console panel.

3. Type in XPath like $x(".//header") to evaluate and validate.

4. Type in CSS selectors like $$("header") to evaluate and validate.

5. Check results returned from console execution.

If elements are matched, they will be returned in a list. Otherwise an empty list [ ] is shown.

$x(".//article")
[<article class="unit-article layout-post">…</article>]

$x(".//not-a-tag")
[ ]

If the XPath or CSS selector is invalid, an exception will be shown in red text. For example:

$x(".//header/")
SyntaxError: Failed to execute 'evaluate' on 'Document': The string './/header/' is not a valid XPath expression.

$$("header[id=]")
SyntaxError: Failed to execute 'querySelectorAll' on 'Document': 'header[id=]' is not a valid selector.

This is not possible. If you want to display text inside a rect element you should put them both in a group with the text element coming after the rect element ( so it appears on top ).

<svg xmlns="http://www.w3.org/2000/svg">_x000D_
  <g>_x000D_
    <rect x="0" y="0" width="100" height="100" fill="red"></rect>_x000D_
    <text x="0" y="50" font-family="Verdana" font-size="35" fill="blue">Hello</text>_x000D_
  </g>_x000D_
</svg>

If you are doing a presentation, and you don't care about anything lining up, Verdana is a good choice.

If you are going to distribute your presentation, use a font that you know is on everyone's machine, since using something else is going to cause the machine to fall back to one of the common fonts (like Arial or Times) anyway.

If you do care about things lining up, and are not distributing the presentation, consider Consolas:

It is highly legible, reminiscent of Verdana, and is monospaced. The color choices are, of course, a matter of taste.

We can write directly too...

DECLARE @SearchLetter CHAR(1) 

SET @SearchLetter = 'A' 

SELECT * 
FROM   CUSTOMERS 
WHERE  CONTACTNAME LIKE @SearchLetter + '%' 
       AND REGION = 'WY' 

or the following way as well if we have to append all the search characters then,

DECLARE @SearchLetter CHAR(1) 

SET @SearchLetter = 'A' + '%' 

SELECT * 
FROM   CUSTOMERS 
WHERE  CONTACTNAME LIKE @SearchLetter 
       AND REGION = 'WY' 

Both these will work

you should change the jdk path in eclipse.ini here:

/Users/you_username/eclipse/jee-photon/Eclipse.app/Contents/Eclipse/eclipse.ini

after you should restart eclipse :)

you could try this one if it's a lowres cgi 2D Image Filter

Another solution would be to create a helper class How to Create helper classes here

class Helper{
     public static function format_message($message,$type)
    {
         return '<p class="alert alert-'.$type.'">'.$message.'</p>'
    }
}

Then you can do this.

Redirect::to('users/login')->with('message', Helper::format_message('A bla blah occured','error'));

or

Redirect::to('users/login')->with('message', Helper::format_message('Thanks for registering!','info'));

and in your view

@if(Session::has('message'))
    {{Session::get('message')}}
@endif

I've searched config parsing libraries for my project recently and found these libraries:

• http://www.hyperrealm.com/libconfig/ - small but powerfull and easy-to-use library, examples of using are in the source package and here
• http://pocoproject.org/docs/Poco.Util.PropertyFileConfiguration.html - a part of pocoproject. You can use abstraction in your code and behind that use various supported implementations (ini files, Xml configs, even environment variables)

Another way:

$c = 'A';
$chars = array($c);
while ($c < 'Z') $chars[] = ++$c;

Depending on what kind of image you have, it might be better to rework the design so that the main image fades to a set solid color or repeatable pattern. If you center the image in the page and have the solid color as the backgroud.

See http://www.webdesignerwall.com/trends/80-large-background-websites/ for examples of sites using large or scalable backgrounds.

You do not need {{}} in when conditions. What you are searching for is:

- fail: msg="unsupported version"
  when: version not in acceptable_versions

A bit of powershell magic will do the trick:

cmdkey /add:"SERVER:1433" /user:"DOMAIN\USERNAME" /pass:"PASSWORD"

Then just select windows authentication

I use NUnit and in my project directory I have a copy of my App.Config that I change some configuration (example I redirect to a test database...). You need to have it in the same directory of the tested project and you will be fine.

Here is an example of one of our stored procedures that executes multiple stored procedures within it:

ALTER PROCEDURE [dbo].[AssetLibrary_AssetDelete]
(
    @AssetID AS uniqueidentifier
)
AS

SET NOCOUNT ON

SET TRANSACTION ISOLATION LEVEL READ COMMITTED

EXEC AssetLibrary_AssetDeleteAttributes @AssetID
EXEC AssetLibrary_AssetDeleteComponents @AssetID
EXEC AssetLibrary_AssetDeleteAgreements @AssetID
EXEC AssetLibrary_AssetDeleteMaintenance @AssetID

DELETE FROM
    AssetLibrary_Asset
WHERE
    AssetLibrary_Asset.AssetID = @AssetID

RETURN (@@ERROR)

A few comments:

• The Nyquist frequency is half the sampling rate.
• You are working with regularly sampled data, so you want a digital filter, not an analog filter. This means you should not use analog=True in the call to butter, and you should use scipy.signal.freqz (not freqs) to generate the frequency response.
• One goal of those short utility functions is to allow you to leave all your frequencies expressed in Hz. You shouldn't have to convert to rad/sec. As long as you express your frequencies with consistent units, the scaling in the utility functions takes care of the normalization for you.

Here's my modified version of your script, followed by the plot that it generates.

import numpy as np
from scipy.signal import butter, lfilter, freqz
import matplotlib.pyplot as plt


def butter_lowpass(cutoff, fs, order=5):
    nyq = 0.5 * fs
    normal_cutoff = cutoff / nyq
    b, a = butter(order, normal_cutoff, btype='low', analog=False)
    return b, a

def butter_lowpass_filter(data, cutoff, fs, order=5):
    b, a = butter_lowpass(cutoff, fs, order=order)
    y = lfilter(b, a, data)
    return y


# Filter requirements.
order = 6
fs = 30.0       # sample rate, Hz
cutoff = 3.667  # desired cutoff frequency of the filter, Hz

# Get the filter coefficients so we can check its frequency response.
b, a = butter_lowpass(cutoff, fs, order)

# Plot the frequency response.
w, h = freqz(b, a, worN=8000)
plt.subplot(2, 1, 1)
plt.plot(0.5*fs*w/np.pi, np.abs(h), 'b')
plt.plot(cutoff, 0.5*np.sqrt(2), 'ko')
plt.axvline(cutoff, color='k')
plt.xlim(0, 0.5*fs)
plt.title("Lowpass Filter Frequency Response")
plt.xlabel('Frequency [Hz]')
plt.grid()


# Demonstrate the use of the filter.
# First make some data to be filtered.
T = 5.0         # seconds
n = int(T * fs) # total number of samples
t = np.linspace(0, T, n, endpoint=False)
# "Noisy" data.  We want to recover the 1.2 Hz signal from this.
data = np.sin(1.2*2*np.pi*t) + 1.5*np.cos(9*2*np.pi*t) + 0.5*np.sin(12.0*2*np.pi*t)

# Filter the data, and plot both the original and filtered signals.
y = butter_lowpass_filter(data, cutoff, fs, order)

plt.subplot(2, 1, 2)
plt.plot(t, data, 'b-', label='data')
plt.plot(t, y, 'g-', linewidth=2, label='filtered data')
plt.xlabel('Time [sec]')
plt.grid()
plt.legend()

plt.subplots_adjust(hspace=0.35)
plt.show()

Sometimes even autocomplete=off would not prevent to fill in credentials into wrong fields, but not user or nickname field.

This workaround is in addition to apinstein's post about browser behavior.

fix browser autofill in read-only and set writable on focus (click and tab)

 <input type="password" readonly  
     onfocus="this.removeAttribute('readonly');"/>

Update: Mobile Safari sets cursor in the field, but does not show virtual keyboard. New Fix works like before but handles virtual keyboard:

<input id="email" readonly type="email" onfocus="if (this.hasAttribute('readonly')) {
    this.removeAttribute('readonly');
    // fix for mobile safari to show virtual keyboard
    this.blur();    this.focus();  }" />

Live Demo https://jsfiddle.net/danielsuess/n0scguv6/

// UpdateEnd

Because Browser auto fills credentials to wrong text field!?

I notice this strange behavior on Chrome and Safari, when there are password fields in the same form. I guess, the browser looks for a password field to insert your saved credentials. Then it auto fills (just guessing due to observation) the nearest textlike-input field, that appears prior the password field in DOM. As the browser is the last instance and you can not control it,

This readonly-fix above worked for me.

for use sample touch listener just you need this code

@Override
public boolean onTouch(View view, MotionEvent motionEvent) {

    ClipData data = ClipData.newPlainText("", "");
    View.DragShadowBuilder shadowBuilder = new View.DragShadowBuilder(view);
    view.startDrag(data, shadowBuilder, null, 0);

    return true;
}

You need to use a Collection List. You cannot re-dimension an array.

You can only send 1 object as a parameter in the body via post. I would change your Post method to

public void Post(ICollection<Product> products)
{
}

and in your angular code you would pass up a product array in JSON notation

The bottom statement is equivalent to:

.half {
   flex-grow: 0;
   flex-shrink: 0;
   flex-basis: 50%;
}

Which, in this case, would be equivalent as the box is not allowed to flex and therefore retains the initial width set by flex-basis.

Flex-basis defines the default size of an element before the remaining space is distributed so if the element were allowed to flex (grow/shrink) it may not be 50% of the width of the page.

I've found that I regularly return to https://css-tricks.com/snippets/css/a-guide-to-flexbox/ for help regarding flexbox :)

The settings you need are "Local echo" and "Line editing" under the "Terminal" category on the left.

To get the characters to display on the screen as you enter them, set "Local echo" to "Force on".

To get the terminal to not send the command until you press Enter, set "Local line editing" to "Force on".

Explanation:

From the PuTTY User Manual (Found by clicking on the "Help" button in PuTTY):

4.3.8 ‘Local echo’

With local echo disabled, characters you type into the PuTTY window are not echoed in the window by PuTTY. They are simply sent to the server. (The server might choose to echo them back to you; this can't be controlled from the PuTTY control panel.)

Some types of session need local echo, and many do not. In its default mode, PuTTY will automatically attempt to deduce whether or not local echo is appropriate for the session you are working in. If you find it has made the wrong decision, you can use this configuration option to override its choice: you can force local echo to be turned on, or force it to be turned off, instead of relying on the automatic detection.

4.3.9 ‘Local line editing’ Normally, every character you type into the PuTTY window is sent immediately to the server the moment you type it.

If you enable local line editing, this changes. PuTTY will let you edit a whole line at a time locally, and the line will only be sent to the server when you press Return. If you make a mistake, you can use the Backspace key to correct it before you press Return, and the server will never see the mistake.

Since it is hard to edit a line locally without being able to see it, local line editing is mostly used in conjunction with local echo (section 4.3.8). This makes it ideal for use in raw mode or when connecting to MUDs or talkers. (Although some more advanced MUDs do occasionally turn local line editing on and turn local echo off, in order to accept a password from the user.)

Some types of session need local line editing, and many do not. In its default mode, PuTTY will automatically attempt to deduce whether or not local line editing is appropriate for the session you are working in. If you find it has made the wrong decision, you can use this configuration option to override its choice: you can force local line editing to be turned on, or force it to be turned off, instead of relying on the automatic detection.

Putty sometimes makes wrong choices when "Auto" is enabled for these options because it tries to detect the connection configuration. Applied to serial line, this is a bit trickier to do.

Add the css styling text-align: center to the control.

Ideally you would do this through a css class assigned to the control, but if you must do it directly, here is an example:

<asp:TextBox ID="myTextBox" runat="server" style="text-align: center"></asp:TextBox>

I had the same doubt as you until I came across this book by the C++ Guru Scott Meyers. Refer the third Item in this book where he talks in details about using const.

Just follow this advice

1. If the word const appears to the left of the asterisk, what's pointed to is constant
2. If the word const appears to the right of the asterisk, the pointer itself is constant
3. If const appears on both sides, both are constant

If you are using JSP 2.0 and above It will come with the EL support: so that you can write in plain english and use and with empty operators to write your test:

<c:if test="${(empty object_1.attribute_A) and (empty object_2.attribute_B)}">

You can use this to check if there are any results ($result) from a query:

if (mysqli_num_rows($result) != 0)
 {
  //results found
 } else {
  // results not found
 }

Use:

$filelist = @("11", "1", "2")
$filelist | sort @{expression={[int]$_}} | % {$newName = [string]([int]$_ + 1)}
New-Item $newName -ItemType Directory

I made it work by doing this:

tableView.separatorInset = UIEdgeInsetsZero;
tableView.layoutMargins = UIEdgeInsetsZero;
cell.layoutMargins = UIEdgeInsetsZero;

Right Click on Project--> Add--> New Project-->click on Class Library.

Now your class library is created as class1.cs

Right Click on References(of your program/console app)

-->Add Reference-->classLibrary1(whatever you named) Now mention "using ClassLibrary1" in your program/console app

Now u can easily call the method/property in your console app

I had the same problem, but i solved it from Java Control Panel-->Security-->SecurityLevel:MEDIUM. Just so, no Manage certificates, imports ,exports etc..

I really don't know what was so hard about this question, but I managed to do it this way:

[myStringContainingInt intValue];

It should be noted that you can also do:

myStringContainingInt.intValue;

if you include the / at the start of the include, the include will be taken as the path from the root of the site.

if your site is http://www.example.com/game/forum/files/index.php you can add an include to /includes/boot.inc.php which would resolve to http://www.example.com/includes/boot.inc.php .

You have to be careful with .. traversal as some web servers have it disabled; it also causes problems when you want to move your site to a new machine/host and the structure is a little different.

Lots of ways to do this. The most reliable is find.

Dim rLastCell As Range

Set rLastCell = ws.Cells.Find(What:="*", After:=ws.Cells(1, 1), LookIn:=xlFormulas, LookAt:= _
xlPart, SearchOrder:=xlByColumns, SearchDirection:=xlPrevious, MatchCase:=False)

MsgBox ("The last used column is: " & rLastCell.Column)

If you want to find the last column used in a particular row you can use:

Dim lColumn As Long

lColumn = ws.Cells(1, Columns.Count).End(xlToLeft).Column

Using used range (less reliable):

Dim lColumn As Long

lColumn = ws.UsedRange.Columns.Count

Using used range wont work if you have no data in column A. See here for another issue with used range:

See Here regarding resetting used range.

This worked for me for printing response with header:

wget --server-response http://www.example.com/

Unlike other source control systems like SVN or CVS, git stores all of its metadata in a single directory, rather than in every subdirectory of the project. So just delete .git from the root (or use a script like git-export) and you should be fine.

df['y'] will set a column

since you want to set a row, use .loc

Note that .ix is equivalent here, yours failed because you tried to assign a dictionary to each element of the row y probably not what you want; converting to a Series tells pandas that you want to align the input (for example you then don't have to to specify all of the elements)

In [7]: df = pandas.DataFrame(columns=['a','b','c','d'], index=['x','y','z'])

In [8]: df.loc['y'] = pandas.Series({'a':1, 'b':5, 'c':2, 'd':3})

In [9]: df
Out[9]: 
     a    b    c    d
x  NaN  NaN  NaN  NaN
y    1    5    2    3
z  NaN  NaN  NaN  NaN

Try the following:

df[df['Col2'].isnull()]

You can also make this a little simpler by using the following inside the event code:

private void MyDataGridView_MouseDown(object sender, MouseEventArgs e) 
{     
    if (e.Button == MouseButtons.Right)     
    {         
        rowToDelete = e.RowIndex;
        MyDataGridView.Rows.RemoveAt(rowToDelete);         
        MyDataGridView.ClearSelection();     
    } 
}

EDIT: I've added one more option for bootstrap sidebars.

There are actually three manners in which you can make a bootstrap 3 sidebar. I tried to keep the code as simple as possible.

Fixed sidebar

Here you can see a demo of a simple fixed sidebar I've developed with the same height as the page

Sidebar in a column

I've also developed a rather simple column sidebar that works in a two or three column page inside a container. It takes the length of the longest column. Here you can see a demo

Dashboard

If you google bootstrap dashboard, you can find multiple suitable dashboard, such as this one. However, most of them require a lot of coding. I've developed a dashboard that works without additional javascript (next to the bootstrap javascript). Here is a demo

For all three examples you off course have to include the jquery, bootstrap css, js and theme.css files.

Slidebar

If you want the sidebar to hide on pressing a button this is also possible with only a little javascript.Here is a demo

<input type='text' minlength=3 /><br />

if browser supports html5,

it will automatical be validate attributes(minlength) in tag

but Safari(iOS) doesn't working

You can keep rsouces directory in Directory NetBeans: Web Pages Eclipse: webapps

Fetch vs Pull

Git fetch just updates your repo data, but a git pull will basically perform a fetch and then merge the branch pulled

What is the difference between 'git pull' and 'git fetch'?

Merge vs Rebase

from Atlassian SourceTree Blog, Merge or Rebase:

Merging brings two lines of development together while preserving the ancestry of each commit history.

In contrast, rebasing unifies the lines of development by re-writing changes from the source branch so that they appear as children of the destination branch – effectively pretending that those commits were written on top of the destination branch all along.

Also, check out Learn Git Branching, which is a nice game that has just been posted to HackerNews (link to post) and teaches a lot of branching and merging tricks. I believe it will be very helpful in this matter.

I faced this error when I was trying to build Selenium source on Ubuntu. The simple shell script with correct shebang was not able to run even after I had all pre-requisites covered.

file file-name # helped me in understanding that CRLF ending were present in the file.

I opened the file in Vim and I could see that just because I once edited this file on a Windows machine, it was in DOS format. I converted the file to Unix format with below command:

dos2unix filename # actually helped me and things were fine.

I hope that we should take care whenever we edit files across platforms we should take care for the file formats as well.

Open the file again using vi. and then press " i " or press insert key ,

For save and quit

  Enter Esc    

and write the following command

  :wq

without save and quit

  :q!

Using a regex as you described is the simple way (as far as I am aware). If you want a range you could use [^a-f].

An example of Python's way of doing "ternary" expressions:

i = 5 if a > 7 else 0

translates into

if a > 7:
   i = 5
else:
   i = 0

This actually comes in handy when using list comprehensions, or sometimes in return statements, otherwise I'm not sure it helps that much in creating readable code.

The readability issue was discussed at length in this recent SO question better way than using if-else statement in python.

It also contains various other clever (and somewhat obfuscated) ways to accomplish the same task. It's worth a read just based on those posts.

Another example using Deferreds to implement a cache for any kind of computation (typically some performance-intensive or long-running tasks):

var ResultsCache = function(computationFunction, cacheKeyGenerator) {
    this._cache = {};
    this._computationFunction = computationFunction;
    if (cacheKeyGenerator)
        this._cacheKeyGenerator = cacheKeyGenerator;
};

ResultsCache.prototype.compute = function() {
    // try to retrieve computation from cache
    var cacheKey = this._cacheKeyGenerator.apply(this, arguments);
    var promise = this._cache[cacheKey];

    // if not yet cached: start computation and store promise in cache 
    if (!promise) {
        var deferred = $.Deferred();
        promise = deferred.promise();
        this._cache[cacheKey] = promise;

        // perform the computation
        var args = Array.prototype.slice.call(arguments);
        args.push(deferred.resolve);
        this._computationFunction.apply(null, args);
    }

    return promise;
};

// Default cache key generator (works with Booleans, Strings, Numbers and Dates)
// You will need to create your own key generator if you work with Arrays etc.
ResultsCache.prototype._cacheKeyGenerator = function(args) {
    return Array.prototype.slice.call(arguments).join("|");
};

Here is an example of using this class to perform some (simulated heavy) calculation:

// The addingMachine will add two numbers
var addingMachine = new ResultsCache(function(a, b, resultHandler) {
    console.log("Performing computation: adding " + a + " and " + b);
    // simulate rather long calculation time by using a 1s timeout
    setTimeout(function() {
        var result = a + b;
        resultHandler(result);
    }, 1000);
});

addingMachine.compute(2, 4).then(function(result) {
    console.log("result: " + result);
});

addingMachine.compute(1, 1).then(function(result) {
    console.log("result: " + result);
});

// cached result will be used
addingMachine.compute(2, 4).then(function(result) {
    console.log("result: " + result);
});

The same underlying cache could be used to cache Ajax requests:

var ajaxCache = new ResultsCache(function(id, resultHandler) {
    console.log("Performing Ajax request for id '" + id + "'");
    $.getJSON('http://jsfiddle.net/echo/jsonp/?callback=?', {value: id}, function(data) {
        resultHandler(data.value);
    });
});

ajaxCache.compute("anID").then(function(result) {
    console.log("result: " + result);
});

ajaxCache.compute("anotherID").then(function(result) {
    console.log("result: " + result);
});

// cached result will be used
ajaxCache.compute("anID").then(function(result) {
    console.log("result: " + result);
});

You can play with the above code in this jsFiddle.

If you want to enable unblur, you cannot just add the blur CSS to the body, you need to blur each visible child one level directly under the body and then remove the CSS to unblur. The reason is because of the "Cascade" in CSS, you cannot undo the cascading of the CSS blur effect for a child of the body. Also, to blur the body's background image you need to use the pseudo element :before

[Code Igniter frame work] [Import library]

Try right-clicking on the project in a Project Explorer view, choose refresh. All error markers are gone surprisingly to my case.

I'm not good at Eclipse. I started using Android Studio to develop Android. But, it's annoying to see red error markers hovering all the time whilst the whole project still works fine. It happened to me when I use composer to import library like this:

require __DIR__ . '/../../vendor/autoload.php';

use \Firebase\JWT\JWT;

inputString.splitlines()

Will give you a list with each item, the splitlines() method is designed to split each line into a list element.

This only work below IE 11 version.

var ie_version = parseInt(window.navigator.userAgent.substring(window.navigator.userAgent.indexOf("MSIE ") + 5, window.navigator.userAgent.indexOf(".", window.navigator.userAgent.indexOf("MSIE "))));

console.log("version number",ie_version);

Little Edit

Try adding

return new JavascriptResult() { Script = "alert('Successfully registered');" };

in place of

return RedirectToAction("Index");

The definition of method_two is invalid. When you call method_two, you'll get TypeError: method_two() takes 0 positional arguments but 1 was given from the interpreter.

An instance method is a bounded function when you call it like a_test.method_two(). It automatically accepts self, which points to an instance of Test, as its first parameter. Through the self parameter, an instance method can freely access attributes and modify them on the same object.

Execute following commands:

brew update
brew install openssl
echo 'export PATH="/usr/local/opt/openssl/bin:$PATH"' >> ~/.bash_profile
source ~/.bash_profile

You will have the latest version of openssl installed and accessible from cli (command line/terminal). Since the third command will add export path to .bash_profile, the newly installed version of openssl will be accessible across system restarts.

you would just do this

l = [0, 1, 2, 3, 4]
l.pop(0)

or l = l[1:]

Pros and Cons

Using pop you can retrieve the value

say x = l.pop(0) x would be 0

When inserting a row, regardless of the CopyOrigin, Excel will only put vertical borders on the inserted cells if the borders above and below the insert position are the same.

I'm running into a similar (but rotated) situation with inserting columns, but Copy/Paste is too slow for my workbook (tens of thousands of rows, many columns, and complex formatting).

I've found three workarounds that don't require copying the formatting from the source row:

1. Ensure the vertical borders are the same weight, color, and pattern above and below the insert position so Excel will replicate them in your new row. (This is the "It hurts when I do this," "Stop doing that!" answer.)

2. Use conditional formatting to establish the border (with a Formula of "=TRUE"). The conditional formatting will be copied to the new row, so you still end up with a border.Caveats:

   • Conditional formatting borders are limited to the thin-weight lines.
   • Works best for sheets where borders are relatively consistent so you don't have to create a bunch of conditional formatting rules.

3. Set the border on the inserted row in VBA after inserting the row. Setting a border on a range is much faster than copying and pasting all of the formatting just to get a border (assuming you know ahead of time what the border should be or can sample it from the row above without losing performance).

I fixed this on my PC, on my environment iReport was iReport-5.1.0 , both jdk 7 and jdk 8 had been installed.

but iReport did not load

fix:- 1. Find the iReport.conf //C:\Program Files (x86)\Jaspersoft\iReport-5.1.0\etc

2. Open it on text editor

3. copy your jdk installation path //C:\Program Files (x86)\Java\jdk1.8.0_60

4. add jdkhome= into the ireport.conf file jdkhome="C:/Program Files (x86)/Java/jdk1.8.0_60"

Now iReport will work

Yes, the constant CI_VERSION will give you the current CodeIgniter version number. It's defined in: /system/codeigniter/CodeIgniter.php As of CodeIgniter 2, it's defined in /system/core/CodeIgniter.php

For example,

echo CI_VERSION; // echoes something like 1.7.1

I had the same problem and tired all the above solutions and did not work for me! the problem was because multiple networks make conflict between VMware and VirtualBox, and other VPN connections. The solution i followed is:

• solution 1 :

uninstall virtualbox and reinstall the last update of it

• solution 2 :

If solution 1 not working, try this uninstalling all VPN programs, VirtualBox, Genymotion and reinstalled VirtualBox and Genymotion again. both solutions worked with me

I want to serialize objects to strings, and back.

Different from the other answers, but the most straightforward way to do exactly that for most object types is XmlSerializer:

        Subject subject = new Subject();
        XmlSerializer serializer = new XmlSerializer(typeof(Subject));
        using (Stream stream = new MemoryStream())
        {
            serializer.Serialize(stream, subject);
            // do something with stream
            Subject subject2 = (Subject)serializer.Deserialize(stream);
            // do something with subject2
        }

All your public properties of supported types will be serialized. Even some collection structures are supported, and will tunnel down to sub-object properties. You can control how the serialization works with attributes on your properties.

This does not work with all object types, some data types are not supported for serialization, but overall it is pretty powerful, and you don't have to worry about encoding.

You can always do something like this:

update  mytable t
set     SomeColumn = c.ComputedValue
from    (select *, 42 as ComputedValue from mytable where id = 1) c
where t.id = c.id 

You can now also use with statement inside update

update  mytable t
set     SomeColumn = c.ComputedValue
from    (with abc as (select *, 43 as ComputedValue_new from mytable where id = 1
         select *, 42 as ComputedValue, abc.ComputedValue_new  from mytable n1
           inner join abc on n1.id=abc.id) c
where t.id = c.id 

$('#div_id').css({marginTop: '-=15px'});

This will alter the css for the element with the id "div_id"

To get the effect you want I recommend adding the code above to a callback function in your animation (that way the div will be moved up after the animation is complete):

$('#div_id').animate({...}, function () {
    $('#div_id').css({marginTop: '-=15px'});
});

And of course you could animate the change in margin like so:

$('#div_id').animate({marginTop: '-=15px'});

For image data, I find it simpler to use canvas.toBlob (asynchronous)

function b64toBlob(b64, onsuccess, onerror) {
    var img = new Image();

    img.onerror = onerror;

    img.onload = function onload() {
        var canvas = document.createElement('canvas');
        canvas.width = img.width;
        canvas.height = img.height;

        var ctx = canvas.getContext('2d');
        ctx.drawImage(img, 0, 0, canvas.width, canvas.height);

        canvas.toBlob(onsuccess);
    };

    img.src = b64;
}

var base64Data = 'data:image/jpg;base64,/9j/4AAQSkZJRgABAQA...';
b64toBlob(base64Data,
    function(blob) {
        var url = window.URL.createObjectURL(blob);
        // do something with url
    }, function(error) {
        // handle error
    });

Maybe it is easier to convert the Date into the actual integer 20110506105524 and then convert this into a string:

function printDate() {
    var temp = new Date();
    var dateInt =
        ((((temp.getFullYear() * 100 + 
            temp.getMonth() + 1) * 100 + 
           temp.getDate()) * 100 +
          temp.getHours()) * 100 + 
         temp.getMinutes()) * 100 + 
        temp.getSeconds();

    debug ( '' + dateInt );  // convert to String
}

When temp.getFullYear() < 1000 the result will be one (or more) digits shorter.

Caution: this wont work with millisecond precision (i.e. 17 digits) since Number.MAX_SAFE_INTEGER is 9007199254740991 which is only 16 digits.

1. From terminal, find all eclipse directories with

   sudo find / -iname "Eclipse"

2. Delete those directories with rm command.

I use the \! command within MySQL to grep out NULL values from the shell:

\! mysql -e "SELECT * FROM table WHERE column = 123456\G" | grep -v NULL

It works best with a proper .my.cnf where your database/username/password are specified. That way you just have to surround your select with \! mysql e and | grep -v NULL.

Your task declaration is incorrectly combining the Copy task type and project.copy method, resulting in a task that has nothing to copy and thus never runs. Besides, Copy isn't the right choice for renaming a directory. There is no Gradle API for renaming, but a bit of Groovy code (leveraging Java's File API) will do. Assuming Project1 is the project directory:

task renABCToXYZ {     doLast {         file("ABC").renameTo(file("XYZ"))     } } 

Looking at the bigger picture, it's probably better to add the renaming logic (i.e. the doLast task action) to the task that produces ABC.

To create a migration, you may use the migrate:make command on the Artisan CLI. Use a specific name to avoid clashing with existing models

for Laravel 3:

php artisan migrate:make add_paid_to_users

for Laravel 5+:

php artisan make:migration add_paid_to_users_table --table=users

You then need to use the Schema::table() method (as you're accessing an existing table, not creating a new one). And you can add a column like this:

public function up()
{
    Schema::table('users', function($table) {
        $table->integer('paid');
    });
}

and don't forget to add the rollback option:

public function down()
{
    Schema::table('users', function($table) {
        $table->dropColumn('paid');
    });
}

Then you can run your migrations:

php artisan migrate

This is all well covered in the documentation for both Laravel 3:

• Schema Builder
• Migrations

And for Laravel 4 / Laravel 5:

• Schema Builder
• Migrations

Edit:

use $table->integer('paid')->after('whichever_column'); to add this field after specific column.

you can use those function it's so easy the First one for encryption so you just call the function and send the text you wanna encrypt it and take the result from encryptWithAES function and send it to decrypt Function like this:

const CryptoJS = require("crypto-js");


   //The Function Below To Encrypt Text
   const encryptWithAES = (text) => {
      const passphrase = "My Secret Passphrase";
      return CryptoJS.AES.encrypt(text, passphrase).toString();
    };
    //The Function Below To Decrypt Text
    const decryptWithAES = (ciphertext) => {
      const passphrase = "My Secret Passphrase";
      const bytes = CryptoJS.AES.decrypt(ciphertext, passphrase);
      const originalText = bytes.toString(CryptoJS.enc.Utf8);
      return originalText;
    };

  let encryptText = encryptWithAES("YAZAN"); 
  //EncryptedText==>  //U2FsdGVkX19GgWeS66m0xxRUVxfpI60uVkWRedyU15I= 

  let decryptText = decryptWithAES(encryptText);
  //decryptText==>  //YAZAN 

You can use the command line cc.rnl ', ' of ConyEdit (a plugin) to replace new lines with the contents you want.

Note: Parent constructors are not called implicitly if the child class defines a constructor. In order to run a parent constructor, a call to parent::__construct() within the child constructor is required. If the child does not define a constructor then it may be inherited from the parent class just like a normal class method (if it was not declared as private).

Swift 4

AppDelegate

var orientationLock = UIInterfaceOrientationMask.all

func application(_ application: UIApplication, supportedInterfaceOrientationsFor window: UIWindow?) -> UIInterfaceOrientationMask {
    return self.orientationLock
}
struct AppUtility {
    static func lockOrientation(_ orientation: UIInterfaceOrientationMask) {
        if let delegate = UIApplication.shared.delegate as? AppDelegate {
            delegate.orientationLock = orientation
        }
    }

    static func lockOrientation(_ orientation: UIInterfaceOrientationMask, andRotateTo rotateOrientation:UIInterfaceOrientation) {
        self.lockOrientation(orientation)
        UIDevice.current.setValue(rotateOrientation.rawValue, forKey: "orientation")
    }
}

Your ViewController Add Following line if you need only portrait orientation. you have to apply this to all ViewController need to display portrait mode.

override func viewWillAppear(_ animated: Bool) {
AppDelegate.AppUtility.lockOrientation(UIInterfaceOrientationMask.portrait, andRotateTo: UIInterfaceOrientation.portrait)
    }

and that will make screen orientation for others Viewcontroller according to device physical orientation.

override func viewWillDisappear(_ animated: Bool) {
        AppDelegate.AppUtility.lockOrientation(UIInterfaceOrientationMask.all)

    }

Search & Remove duplicate files those are produced from multiple commands.

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

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

No my friend its very simple, try using this:

AlertDialog alertDialog = new AlertDialog.Builder(AlertDialogActivity.this).create();
alertDialog.setTitle("Alert Dialog");
alertDialog.setMessage("Welcome to dear user.");
alertDialog.setIcon(R.drawable.welcome);

alertDialog.setButton(AlertDialog.BUTTON_POSITIVE, "OK", new DialogInterface.OnClickListener() {
    public void onClick(DialogInterface dialog, int which) {
        Toast.makeText(getApplicationContext(), "You clicked on OK", Toast.LENGTH_SHORT).show();
    }
});

alertDialog.show();

This tutorial shows how you can create custom dialog using xml and then show them as an alert dialog.

java.lang.Integer is not a super class of BigInteger. Both BigInteger and Integer do inherit from java.lang.Number, so you could cast to a java.lang.Number.

See the java docs http://docs.oracle.com/javase/1.5.0/docs/api/java/lang/Number.html

As for someone don't like gray background like academic editor, try this:

p <- p + theme_bw()
p

you could have a computed property that returns a boolean dependent on whatever criteria you need.

<input type="text" :disabled=isDisabled>

then put your logic in a computed property...

computed: {
  isDisabled() {
    // evaluate whatever you need to determine disabled here...
    return this.form.validated;
  }
}

A slight variation on Richards answer but readTree can take a string so you can simplify it to:

ObjectMapper mapper = new ObjectMapper();
JsonNode actualObj = mapper.readTree("{\"k1\":\"v1\"}");

I had a similiar post here, addEventListener load on ajax load WITHOUT jquery

How I solved it was to insert calls to functions within my stateChange function. The page I had setup was 3 buttons that would load 3 different pages into the contentArea. Because I had to know which button was being pressed to load page 1, 2 or 3, I could easily use if/else statements to determine which page is being loaded and then which function to run. What I was trying to do was register different button listeners that would only work when the specific page was loaded because of element IDs..

so...

if (page1 is being loaded, pageload = 1) run function registerListeners1

then the same for page 2 or 3.

You can also use the didSet to set the variable to a different value. This does not cause the observer to be called again as stated in Properties guide. For example, it is useful when you want to limit the value as below:

let minValue = 1

var value = 1 {
    didSet {
        if value < minValue {
            value = minValue
        }
    }
}

value = -10 // value is minValue now.

just give rowId and type of data that is going to be update in ContentValues.

public void updateStatus(String id , int status){

SQLiteDatabase db = this.getWritableDatabase();

ContentValues data = new ContentValues();

data.put("status", status);

db.update(TableName, data, "columnName" + " = "+id , null);

}

declare function in global scope with window

first.js

window.fn1 = function fn1() {
    alert("external fn clicked");
}

second.js

document.getElementById("btn").onclick = function() {
   fn1();
}

include like this

<script type="text/javascript" src="first.js"></script>
<script type="text/javascript" src="second.js"></script>

You should also use <label for="checkbox1">Checkbox 1</label> because then people can click on the label text as well as the checkbox itself. Its also easier to style and at least in IE it will be highlighted when you tab through the page's controls.

<%= Html.CheckBox("cbNewColors", true) %><label for="cbNewColors">New colors</label>

This is not just a 'oh I could do it' thing. Its a significant user experience enhancement. Even if not all users know they can click on the label many will.

Please try this one works for me:

<ImageView android:id="@+id/image_view"     
  android:layout_width="wrap_content"  
  android:layout_height="wrap_content"  
  android:adjustViewBounds="true"  
  android:maxWidth="60dp" 
  android:layout_gravity="center" 
  android:maxHeight="60dp"  
  android:scaleType="fitCenter"  
  android:src="@drawable/icon"  
  /> 

You can indeed run multiple animations simultaneously, but your example has two problems. First, the syntax you use only specifies one animation. The second style rule hides the first. You can specify two animations using syntax like this:

-webkit-animation-name: spin, scale
-webkit-animation-duration: 2s, 4s

as in this fiddle (where I replaced "scale" with "fade" due to the other problem explained below... Bear with me.): http://jsfiddle.net/rwaldin/fwk5bqt6/

Second, both of your animations alter the same CSS property (transform) of the same DOM element. I don't believe you can do that. You can specify two animations on different elements, the image and a container element perhaps. Just apply one of the animations to the container, as in this fiddle: http://jsfiddle.net/rwaldin/fwk5bqt6/2/
