So I ran into this today.

Was attempting to validate an uploaded CSV file's MIME type by looking at $_FILES['upload_file']['type'], but for certain users on various browsers (and not necessarily the same browsers between said users; for instance it worked fine for me in FF but for another user it didn't work on FF) the $_FILES['upload_file']['type'] was coming up as "application/vnd.ms-excel" instead of the expected "text/csv" or "text/plain".

So I resorted to using the (IMHO) much more reliable finfo_* functions something like this:

$acceptable_mime_types = array('text/plain', 'text/csv', 'text/comma-separated-values');

if (!empty($_FILES) && array_key_exists('upload_file', $_FILES) && $_FILES['upload_file']['error'] == UPLOAD_ERR_OK) {
    $tmpf = $_FILES['upload_file']['tmp_name'];

    // Make sure $tmpf is kosher, then:

    $finfo = finfo_open(FILEINFO_MIME_TYPE);
    $mime_type = finfo_file($finfo, $tmpf);

    if (!in_array($mime_type, $acceptable_mime_types)) {
        // Unacceptable mime type.
    }
}

If you are looking for a programmatical modal creation, you might love this:

http://nakupanda.github.io/bootstrap3-dialog/

Even though Bootstrap's modal provides a javascript way for modal creation, you still need to write modal's html markups first.

You're trying to pass file objects as filenames. Try using

infile = '110331_HS1A_1_rtTA.result'
outfile = '2.txt'

at the top of your code.

(Not only does the doubled usage of open() cause that problem with trying to open the file again, it also means that infile and outfile are never closed during the course of execution, though they'll probably get closed once the program ends.)

Probably you try to send your data from mydomain.com to www.mydomain.com or reverse, NOTE you missed "www". http://mydomain.com and http://www.mydomain.com are different domains to javascript.

To format String use

import org.apache.commons.lang.StringUtils;

public class test {

    public static void main(String[] args) {

        String result = StringUtils.leftPad("wrwer", 10, "0");
        System.out.println("The String : " + result);

    }
}

Output : The String : 00000wrwer

Where the first argument is the string to be formatted, Second argument is the length of the desired output length and third argument is the char with which the string is to be padded.

The quick answer is to use a for() loop in place of your foreach() loops. Something like:

@for(var themeIndex = 0; themeIndex < Model.Theme.Count(); themeIndex++)
{
   @Html.LabelFor(model => model.Theme[themeIndex])

   @for(var productIndex=0; productIndex < Model.Theme[themeIndex].Products.Count(); productIndex++)
   {
      @Html.LabelFor(model=>model.Theme[themeIndex].Products[productIndex].name)
      @for(var orderIndex=0; orderIndex < Model.Theme[themeIndex].Products[productIndex].Orders; orderIndex++)
      {
          @Html.TextBoxFor(model => model.Theme[themeIndex].Products[productIndex].Orders[orderIndex].Quantity)
          @Html.TextAreaFor(model => model.Theme[themeIndex].Products[productIndex].Orders[orderIndex].Note)
          @Html.EditorFor(model => model.Theme[themeIndex].Products[productIndex].Orders[orderIndex].DateRequestedDeliveryFor)
      }
   }
}

But this glosses over why this fixes the problem.

There are three things that you have at least a cursory understanding before you can resolve this issue. I have to admit that I cargo-culted this for a long time when I started working with the framework. And it took me quite a while to really get what was going on.

Those three things are:

• How do the LabelFor and other ...For helpers work in MVC?
• What is an Expression Tree?
• How does the Model Binder work?

All three of these concepts link together to get an answer.

How do the LabelFor and other ...For helpers work in MVC?

So, you've used the HtmlHelper<T> extensions for LabelFor and TextBoxFor and others, and you probably noticed that when you invoke them, you pass them a lambda and it magically generates some html. But how?

So the first thing to notice is the signature for these helpers. Lets look at the simplest overload for TextBoxFor

public static MvcHtmlString TextBoxFor<TModel, TProperty>(
    this HtmlHelper<TModel> htmlHelper,
    Expression<Func<TModel, TProperty>> expression
) 

First, this is an extension method for a strongly typed HtmlHelper, of type <TModel>. So, to simply state what happens behind the scenes, when razor renders this view it generates a class. Inside of this class is an instance of HtmlHelper<TModel> (as the property Html, which is why you can use @Html...), where TModel is the type defined in your @model statement. So in your case, when you are looking at this view TModel will always be of the type ViewModels.MyViewModels.Theme.

Now, the next argument is a bit tricky. So lets look at an invocation

@Html.TextBoxFor(model=>model.SomeProperty);

It looks like we have a little lambda, And if one were to guess the signature, one might think that the type for this argument would simply be a Func<TModel, TProperty>, where TModel is the type of the view model and TProperty is inferred as the type of the property.

But thats not quite right, if you look at the actual type of the argument its Expression<Func<TModel, TProperty>>.

So when you normally generate a lambda, the compiler takes the lambda and compiles it down into MSIL, just like any other function (which is why you can use delegates, method groups, and lambdas more or less interchangeably, because they are just code references.)

However, when the compiler sees that the type is an Expression<>, it doesn't immediately compile the lambda down to MSIL, instead it generates an Expression Tree!

What is an Expression Tree?

So, what the heck is an expression tree. Well, it's not complicated but its not a walk in the park either. To quote ms:

| Expression trees represent code in a tree-like data structure, where each node is an expression, for example, a method call or a binary operation such as x < y.

Simply put, an expression tree is a representation of a function as a collection of "actions".

In the case of model=>model.SomeProperty, the expression tree would have a node in it that says: "Get 'Some Property' from a 'model'"

This expression tree can be compiled into a function that can be invoked, but as long as it's an expression tree, it's just a collection of nodes.

So what is that good for?

So Func<> or Action<>, once you have them, they are pretty much atomic. All you can really do is Invoke() them, aka tell them to do the work they are supposed to do.

Expression<Func<>> on the other hand, represents a collection of actions, which can be appended, manipulated, visited, or compiled and invoked.

So why are you telling me all this?

So with that understanding of what an Expression<> is, we can go back to Html.TextBoxFor. When it renders a textbox, it needs to generate a few things about the property that you are giving it. Things like attributes on the property for validation, and specifically in this case it needs to figure out what to name the <input> tag.

It does this by "walking" the expression tree and building a name. So for an expression like model=>model.SomeProperty, it walks the expression gathering the properties that you are asking for and builds <input name='SomeProperty'>.

For a more complicated example, like model=>model.Foo.Bar.Baz.FooBar, it might generate <input name="Foo.Bar.Baz.FooBar" value="[whatever FooBar is]" />

Make sense? It is not just the work that the Func<> does, but how it does its work is important here.

(Note other frameworks like LINQ to SQL do similar things by walking an expression tree and building a different grammar, that this case a SQL query)

How does the Model Binder work?

So once you get that, we have to briefly talk about the model binder. When the form gets posted, it's simply like a flat Dictionary<string, string>, we have lost the hierarchical structure our nested view model may have had. It's the model binder's job to take this key-value pair combo and attempt to rehydrate an object with some properties. How does it do this? You guessed it, by using the "key" or name of the input that got posted.

So if the form post looks like

Foo.Bar.Baz.FooBar = Hello

And you are posting to a model called SomeViewModel, then it does the reverse of what the helper did in the first place. It looks for a property called "Foo". Then it looks for a property called "Bar" off of "Foo", then it looks for "Baz"... and so on...

Finally it tries to parse the value into the type of "FooBar" and assign it to "FooBar".

PHEW!!!

And voila, you have your model. The instance the Model Binder just constructed gets handed into requested Action.

So your solution doesn't work because the Html.[Type]For() helpers need an expression. And you are just giving them a value. It has no idea what the context is for that value, and it doesn't know what to do with it.

Now some people suggested using partials to render. Now this in theory will work, but probably not the way that you expect. When you render a partial, you are changing the type of TModel, because you are in a different view context. This means that you can describe your property with a shorter expression. It also means when the helper generates the name for your expression, it will be shallow. It will only generate based on the expression it's given (not the entire context).

So lets say you had a partial that just rendered "Baz" (from our example before). Inside that partial you could just say:

@Html.TextBoxFor(model=>model.FooBar)

Rather than

@Html.TextBoxFor(model=>model.Foo.Bar.Baz.FooBar)

That means that it will generate an input tag like this:

<input name="FooBar" />

Which, if you are posting this form to an action that is expecting a large deeply nested ViewModel, then it will try to hydrate a property called FooBar off of TModel. Which at best isn't there, and at worst is something else entirely. If you were posting to a specific action that was accepting a Baz, rather than the root model, then this would work great! In fact, partials are a good way to change your view context, for example if you had a page with multiple forms that all post to different actions, then rendering a partial for each one would be a great idea.

Now once you get all of this, you can start to do really interesting things with Expression<>, by programatically extending them and doing other neat things with them. I won't get into any of that. But, hopefully, this will give you a better understanding of what is going on behind the scenes and why things are acting the way that they are.

To multiply, use mult for signed multiplication and multu for unsigned multiplication. Note that the result of the multiplication of two 32-bit numbers yields a 64-number. If you want the result back in $v0 that means that you assume the result will fit in 32 bits.

The 32 most significant bits will be held in the HI special register (accessible by mfhi instruction) and the 32 least significant bits will be held in the LO special register (accessible by the mflo instruction):

E.g.:

li $a0, 5
li $a1, 3
mult $a0, $a1
mfhi $a2 # 32 most significant bits of multiplication to $a2
mflo $v0 # 32 least significant bits of multiplication to $v0

To divide, use div for signed division and divu for unsigned division. In this case, the HI special register will hold the remainder and the LO special register will hold the quotient of the division.

E.g.:

div $a0, $a1
mfhi $a2 # remainder to $a2
mflo $v0 # quotient to $v0

I added to the migration itself

Schema::defaultStringLength(191);
Schema::create('users', function (Blueprint $table) {
    $table->increments('id');
    $table->string('name');
    $table->string('email')->unique();
    $table->string('password');
    $table->rememberToken();
    $table->timestamps();
});

yes, I know I need to consider it on every migration but I would rather that than have it tucked away in some completely unrelated service provider

Make sure nodejs in the PATH is in front of anything that uses node.

I see two options here

var link = $('a').attr('href');
var equalPosition = link.indexOf('='); //Get the position of '='
var number = link.substring(equalPosition + 1); //Split the string and get the number.

I dont know if you're gonna use it for paging and have the text in the <a>-tag as you have it, but if you should you can also do

var number = $('a').text();

subprocess.Popen() is strict super-set of os.system().

You can call javascript functions from c# using Jering.Javascript.NodeJS, an open-source library by my organization:

string javascriptModule = @"
module.exports = (callback, x, y) => {  // Module must export a function that takes a callback as its first parameter
    var result = x + y; // Your javascript logic
    callback(null /* If an error occurred, provide an error object or message */, result); // Call the callback when you're done.
}";

// Invoke javascript
int result = await StaticNodeJSService.InvokeFromStringAsync<int>(javascriptModule, args: new object[] { 3, 5 });

// result == 8
Assert.Equal(8, result);

The library supports invoking directly from .js files as well. Say you have file C:/My/Directory/exampleModule.js containing:

module.exports = (callback, message) => callback(null, message);

You can invoke the exported function:

string result = await StaticNodeJSService.InvokeFromFileAsync<string>("C:/My/Directory/exampleModule.js", args: new[] { "test" });

// result == "test"
Assert.Equal("test", result);

Sorry to come in late but the OP wants to allow 076 but probably does NOT want to allow 0000000000.

So in this case we want a string of one or more digits containing at least one non-zero. That is

^[0-9]*[1-9][0-9]*$

Give the form an id, and then:

document.getElementById("yourFormId").submit();

Best practice would probably be to give your link an id too, and get rid of the event handler:

document.getElementById("yourLinkId").onclick = function() {
    document.getElementById("yourFormId").submit();
}

For anyone who came here looking for how to get the true accordion effect and only allow one row to be expanded at a time, you can add an event handler for show.bs.collapse like so:

$('.collapse').on('show.bs.collapse', function () {
    $('.collapse.in').collapse('hide');
});

I modified this example to do so here: http://jsfiddle.net/QLfMU/116/

You can use onlinefontconverter.com site. It works fine and have plenty of output formats (afm bin cff dfont eot pfa pfb pfm ps pt3 suit svg t42 tfm ttc ttf woff). One of the advantages I saw, is that it export all the fonts contained inside the ttc at once (which is very convenient).

Just for reference, if you are using:

 $(el).offset().top 

To get the position, it can be affected by the position of the parent element. Thus you may want to be consistent and use the following to set it:

$(el).offset({top: pos});

As opposed to the CSS methods above.

The instantclient works only by defining the folder in the windows PATH environment variable. But you can "install" manually to create some keys in the Windows registry. How?

1) Download instantclient (http://www.oracle.com/technetwork/topics/winsoft-085727.html)

2) Unzip the ZIP file (eg c:\oracle\instantclient).

3) Include the above path in the PATH.

4) Create the registry key:

• Windows 32bit: [HKEY_LOCAL_MACHINE\SOFTWARE\ORACLE]
• Windows 64bit: [HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\ORACLE]

5) In the above registry key, create a sub-key starts with "KEY_" followed by the name of the installation you want:

• Windows 32bit: [HKEY_LOCAL_MACHINE\SOFTWARE\ORACLE\KEY_INSTANTCLIENT]
• Windows 64bit: [HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\ORACLE\KEY_INSTANTCLIENT]

6) Now create at least three string values ??in the above key:

• NLS_LANG = BRAZILIAN PORTUGUESE_BRAZIL.WE8MSWIN1252 (complete list here: http://docs.oracle.com/cd/B19306_01/install.102/b14317/gblsupp.htm)
• ORACLE_HOME = c:\oracle\instantclient (the same folder in PATH)
• ORACLE_HOME_NAME = MY_INSTANTCLIENT (choose any name)

For those who use Quest SQL Navigator or Quest Toad for Oracle will see that it works. Displays the message "Home is valid.":

The registry keys are now displayed for selecting the oracle client:

Let's not forget math.hypot:

dist = math.hypot(x2-x1, y2-y1)

Here's hypot as part of a snippet to compute the length of a path defined by a list of (x, y) tuples:

from math import hypot

pts = [
    (10,10),
    (10,11),
    (20,11),
    (20,10),
    (10,10),
    ]

# Py2 syntax - no longer allowed in Py3
# ptdiff = lambda (p1,p2): (p1[0]-p2[0], p1[1]-p2[1])
ptdiff = lambda p1, p2: (p1[0]-p2[0], p1[1]-p2[1])

diffs = (ptdiff(p1, p2) for p1, p2 in zip (pts, pts[1:]))
path = sum(hypot(*d) for d in  diffs)
print(path)

Take a surprise from gnu11!

typedef struct {
    uint8_t messType;
    uint8_t ax;  //axis
    uint32_t position;
    uint32_t velocity;
}TgotoData;

TgotoData tmpData = { 0 };

nothing is zero.

For Power-Shell

./adb shell getprop | Select-String -Pattern '(model)|(version.sdk)|(manufacturer)|(platform)|(serialno)|(product.name)|(brand)'

For linux(burrowing asnwer from @0x8BADF00D)

adb shell getprop | grep "model\|version.sdk\|manufacturer\|hardware\|platform\|revision\|serialno\|product.name\|brand"

For single string find in power shell

./adb shell getprop | Select-String -Pattern 'model'

or

./adb shell getprop | Select-String -Pattern '(model)'

For multiple

./adb shell getprop | Select-String -Pattern '(a|b|c|d)'

Based on the other answers to this question, I've implemented a new approach using bcrypt.

Why use bcrypt

If I understand correctly, the argument to use bcrypt over SHA512 is that bcrypt is designed to be slow. bcrypt also has an option to adjust how slow you want it to be when generating the hashed password for the first time:

# The '12' is the number that dictates the 'slowness'
bcrypt.hashpw(password, bcrypt.gensalt( 12 ))

Slow is desirable because if a malicious party gets their hands on the table containing hashed passwords, then it is much more difficult to brute force them.

Implementation

def get_hashed_password(plain_text_password):
    # Hash a password for the first time
    #   (Using bcrypt, the salt is saved into the hash itself)
    return bcrypt.hashpw(plain_text_password, bcrypt.gensalt())

def check_password(plain_text_password, hashed_password):
    # Check hashed password. Using bcrypt, the salt is saved into the hash itself
    return bcrypt.checkpw(plain_text_password, hashed_password)

Notes

I was able to install the library pretty easily in a linux system using:

pip install py-bcrypt

However, I had more trouble installing it on my windows systems. It appears to need a patch. See this Stack Overflow question: py-bcrypt installing on win 7 64bit python

If you know the number of elements per "row" and the width of the container you can use a selector to add a margin to the elements you need to cause a justified look.

I had rows of three divs I wanted justified so used the:

.tile:nth-child(3n+2) { margin: 0 10px }

this allows the center div in each row to have a margin that forces the 1st and 3rd div to the outside edges of the container

Also great for other things like borders background colors etc

This is an image from the new version of the article:

strtolower only works on iso-8859-1 encoded strings. You could try with mb_strtolower.

Or, if you have to mangle with multibyte-extensions, you might as well use iconv's transliteration support:

iconv("UTF-8", "ISO-8859-1//TRANSLIT", $text);

Edit:

It seems I was a bit fast. You appear to use iso-8859-1, so your current strategy will work. You just need to write the regexp's properly. Eg.:

'/(ð|é|ê|è|ë)/'

not:

'/[ð|é|ê|è|ë]/'

this works for me

Remove all the texts in android/settings.gradle and paste the below code

rootProject.name = '****Your Project Name****'

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

You can use SHOW:

SHOW max_connections;

This returns the currently effective setting. Be aware that it can differ from the setting in postgresql.conf as there are a multiple ways to set run-time parameters in PostgreSQL. To reset the "original" setting from postgresql.conf in your current session:

RESET max_connections;

However, not applicable to this particular setting. The manual:

This parameter can only be set at server start.

To see all settings:

SHOW ALL;

There is also pg_settings:

The view pg_settings provides access to run-time parameters of the server. It is essentially an alternative interface to the SHOW and SET commands. It also provides access to some facts about each parameter that are not directly available from SHOW, such as minimum and maximum values.

For your original request:

SELECT *
FROM   pg_settings
WHERE  name = 'max_connections';

Finally, there is current_setting(), which can be nested in DML statements:

SELECT current_setting('max_connections');

Another option is to create a exclude list, this is particulary usefull when you have a long list of things to exclude.

vi /root/scripts/exclude_list.txt

Now add what you would like to exclude

Nopaging the limit is
keyword to remove is

Now use grep to remove lines from your file log file and view information not excluded.

grep -v -f /root/scripts/exclude_list.txt /var/log/admin.log

The easiest way is to use the request module.

request('https://example.com/url?a=b', function (error, response, body) {
  if (!error && response.statusCode == 200) {
    console.log(body);
  }
});

You Can do by Two ways,

1. Cloning the Remote Repo to your Local host

example: git clone https://github.com/user-name/repository.git

2. Pulling the Remote Repo to your Local host

First you have to create a git local repo by,

example: git init or git init repo-name then, git pull https://github.com/user-name/repository.git

That's all, All commits and branch in the remote repo now available in the local repository of your computer.

Happy Coding, cheers -:)

I made a slight change though as using it in a Private Sub already.

Dim GetIPAddress()

Dim strHostName As String

Dim strIPAddress As String

strHostName = System.Net.Dns.GetHostName()

strIPAddress = System.Net.Dns.GetHostByName(strHostName).AddressList(0).ToString()

MessageBox.Show("Host Name: " & strHostName & vbCrLf & "IP Address: " & strIPAddress)

But also made a change to the way the details are displayed so that they can show on seperate lines using & vbCrLf &

MessageBox.Show("Host Name: " & strHostName & vbCrLf & "IP Address: " & strIPAddress)

Hope this helps someone.

A simple solution would be to kill the focus, just create your own class:

public class ViewOnlyTextBox : System.Windows.Forms.TextBox {
    // constants for the message sending
    const int WM_SETFOCUS = 0x0007;
    const int WM_KILLFOCUS = 0x0008;

    protected override void WndProc(ref Message m) {
        if(m.Msg == WM_SETFOCUS) m.Msg = WM_KILLFOCUS;

        base.WndProc (ref m);
    }
}

self.navigationItem.rightBarButtonItem=[[[UIBarButtonItem alloc]initWithTitle:@"Save" style:UIBarButtonItemStylePlain target:self action:@selector(saveAction:)]autorelease];

-(void)saveAction:(UIBarButtonItem *)sender{

//perform your action

}

From now on is better to use the .prop() function instead of the .attr() one.

Here the jQuery documentation:

As of jQuery 1.6, the .attr() method returns undefined for attributes that have not been set. In addition, .attr() should not be used on plain objects, arrays, the window, or the document. To retrieve and change DOM properties, use the .prop() method.

var div1Class = $('#div1').prop('class');

The dot itself is not an operator, .^ is.

The .^ is a pointwise¹ (i.e. element-wise) power, as .* is the pointwise product.

.^ Array power. A.^B is the matrix with elements A(i,j) to the B(i,j) power. The sizes of A and B must be the same or be compatible.

C.f.

• "Array vs. Matrix Operations": https://mathworks.com/help/matlab/matlab_prog/array-vs-matrix-operations.html

• "Element-Wise Operations": http://www.glue.umd.edu/afs/glue.umd.edu/system/info/olh/Numerical/Matlab_Matrix_Manipulation_Software/Matrix_Vector_Operations/elementwise

From .NET 2.0 you shouldn't need to do this. If you do not explicitly set the Proxy property on a web request it uses the value of the static WebRequest.DefaultWebProxy. If you wanted to change the proxy being used by all subsequent WebRequests, you can set this static DefaultWebProxy property.

The default behaviour of WebRequest.DefaultWebProxy is to use the same underlying settings as used by Internet Explorer.

If you wanted to use different proxy settings to the current user then you would need to code

WebRequest webRequest = WebRequest.Create("http://stackoverflow.com/");
webRequest.Proxy = new WebProxy("http://proxyserver:80/",true);

or

WebRequest.DefaultWebProxy = new WebProxy("http://proxyserver:80/",true);

You should also remember the object model for proxies includes the concept that the proxy can be different depending on the destination hostname. This can make things a bit confusing when debugging and checking the property of webRequest.Proxy. Call

webRequest.Proxy.GetProxy(new Uri("http://google.com.au")) to see the actual details of the proxy server that would be used.

There seems to be some debate about whether you can set webRequest.Proxy or WebRequest.DefaultWebProxy = null to prevent the use of any proxy. This seems to work OK for me but you could set it to new DefaultProxy() with no parameters to get the required behaviour. Another thing to check is that if a proxy element exists in your applications config file, the .NET Framework will NOT use the proxy settings in Internet Explorer.

The MSDN Magazine article Take the Burden Off Users with Automatic Configuration in .NET gives further details of what is happening under the hood.

public - can be access by anyone anywhere.
private - can only be accessed from with in the class it is a part of.
protected - can only be accessed from with in the class or any object that inherits off of the class.

Nothing is like null but in VB.
Static means you have one instance of that object, method for every instance of that class.

Not to raise the dead after more than a year, but all the previous answers miss some crucial points:

1. @EnableWebMvc on your class will disable org.springframework.boot.autoconfigure.web.WebMvcAutoConfiguration. That's fine if you want complete control but otherwise, it's a problem.

2. There's no need to write any code to add another location for static resources in addition to what is already provided. Looking at org.springframework.boot.autoconfigure.web.ResourceProperties from v1.3.0.RELEASE, I see a field staticLocations that can be configured in the application.properties. Here's a snippet from the source:

   /**
    * Locations of static resources. Defaults to classpath:[/META-INF/resources/,
    * /resources/, /static/, /public/] plus context:/ (the root of the servlet context).
    */
   private String[] staticLocations = RESOURCE_LOCATIONS;
   

3. As mentioned before, the request URL will be resolved relative to these locations. Thus src/main/resources/static/index.html will be served when the request URL is /index.html. The class that is responsible for resolving the path, as of Spring 4.1, is org.springframework.web.servlet.resource.PathResourceResolver.

4. Suffix pattern matching is enabled by default which means for a request URL /index.html, Spring is going to look for handlers corresponding to /index.html. This is an issue if the intention is to serve static content. To disable that, extend WebMvcConfigurerAdapter (but don't use @EnableWebMvc) and override configurePathMatch as shown below:

   @Override
   public void configurePathMatch(PathMatchConfigurer configurer) {
       super.configurePathMatch(configurer);
   
       configurer.setUseSuffixPatternMatch(false);
   }
   

IMHO, the only way to have fewer bugs in your code is not to write code whenever possible. Use what is already provided, even if that takes some research, the return is worth it.

First, update your Virtual Host configuration;

<VirtualHost *:80>
    ServerName example.com
    DocumentRoot /var/www/html/example-project/public
    <Directory /var/www/html/example-project/public/>
        AllowOverride All
        Require all granted
    </Directory>
</VirtualHost>

Then, change both permission and ownership of the asset as illustrated below.

$ sudo chgrp -R www-data /var/www/html/example-project
$ sudo chmod -R 775 /var/www/html/example-project

For naming template parameters, typename and class are equivalent. §14.1.2:

There is no semantic difference between class and typename in a template-parameter.

typename however is possible in another context when using templates - to hint at the compiler that you are referring to a dependent type. §14.6.2:

A name used in a template declaration or definition and that is dependent on a template-parameter is assumed not to name a type unless the applicable name lookup finds a type name or the name is qualified by the keyword typename.

Example:

typename some_template<T>::some_type

Without typename the compiler can't tell in general whether you are referring to a type or not.

[0] or .First() will give you the same performance whatever happens.
But your Dictionary could contains IEnumerable<Component> instead of List<Component>, and then you cant use the [] operator. That is where the difference is huge.

So for your example, it doesn't really matters, but for this code, you have no choice to use First():

var dic = new Dictionary<String, IEnumerable<Component>>();
foreach (var components in dic.Values)
{
    // you can't use [0] because components is an IEnumerable<Component>
    var firstComponent = components.First(); // be aware that it will throw an exception if components is empty.
    var depCountry = firstComponent.ComponentValue("Dep");
}

EDIT

• Class name changed from bar to progress-bar in v3.1.1

jQuery used in the fiddle below and on the document.ready

$(document).ready(function(){

    var progress = setInterval(function() {
        var $bar = $('.bar');

        if ($bar.width()>=400) {
            clearInterval(progress);
            $('.progress').removeClass('active');
        } else {
            $bar.width($bar.width()+40);
        }
        $bar.text($bar.width()/4 + "%");
    }, 800);

});?

Well try ini_set('memory_limit', '256M');

134217728 bytes = 128 MB

Or rewrite the code to consume less memory.

Opsss. after I change user to 'admin', it doesn't have privelege to add database.. so I change back the user to 'root'.

Then I change the password from the browser.

1. Go to http://localhost/security/ and then click on the link http://localhost/security/xamppsecurity.php . After that change pasword for superuser to 'root'.

2. After that open your http://localhost/phpmyadmin/

   Now it works.

Regarding the accepted solution, the one posted by Ashley Davis, the method described still prints the attribute in the DOM, regardless of the fact that the value it has been assigned is undefined.

For example, on an input field setup with both an ng-model and a value attribute:

<input type="text" name="myInput" data-ng-attr-value="{{myValue}}" data-ng-model="myModel" />

Regardless of what's behind myValue, the value attribute still gets printed in the DOM, thus, interpreted. Ng-model then, becomes overridden.

A bit unpleasant, but using ng-if does the trick:

<input type="text" name="myInput" data-ng-if="value" data-ng-attr-value="{{myValue}}" data-ng-model="myModel" />
<input type="text" name="myInput" data-ng-if="!value" data-ng-model="myModel" />

I would recommend using a more detailed check inside the ng-if directives :)

Is it simply that static is for static functions of structs and enums, and class for classes and protocols?

That's the main difference. Some other differences are that class functions are dynamically dispatched and can be overridden by subclasses.

Protocols use the class keyword, but it doesn't exclude structs from implementing the protocol, they just use static instead. Class was chosen for protocols so there wouldn't have to be a third keyword to represent static or class.

From Chris Lattner on this topic:

We considered unifying the syntax (e.g. using "type" as the keyword), but that doesn't actually simply things. The keywords "class" and "static" are good for familiarity and are quite descriptive (once you understand how + methods work), and open the door for potentially adding truly static methods to classes. The primary weirdness of this model is that protocols have to pick a keyword (and we chose "class"), but on balance it is the right tradeoff.

And here's a snippet that shows some of the override behavior of class functions:

class MyClass {
    class func myFunc() {
        println("myClass")
    }
}

class MyOtherClass: MyClass {
    override class func myFunc() {
        println("myOtherClass")
    }
}

var x: MyClass = MyOtherClass()
x.dynamicType.myFunc() //myOtherClass
x = MyClass()
x.dynamicType.myFunc() //myClass

You can change the way Safari opens a new page in Safari > Preferences > Tabs > 'Open pages in tabs instead of windows' > 'Automatically'

The problem with this situation is by using a arraylist you get a time complexity of o(n) for adding at a specific position. If you use an array you create a memory location by declaring your array therefore it is constant

In order to query a table for the number of rows in that table, you want your query to be as efficient as possible. Reference.

Use something like this:

/**
 * Query the Number of Entries in a Sqlite Table
 * */
public long QueryNumEntries()
{
    SQLiteDatabase db = this.getReadableDatabase();
    return DatabaseUtils.queryNumEntries(db, "table_name");
}

<a href="#" onClick="window.open('http://www.yahoo.com', '_blank')">test</a>

Easy as that.

Or without JS

<a href="http://yahoo.com" target="_blank">test</a>

i was facing the same issue and solved it by removing the xmlns:wsu attribute.Try not adding it in the usernameToken.Hope this solves your issue too.

If you want to find out whether a whole word is in a space-separated list of words, simply use:

def contains_word(s, w):
    return (' ' + w + ' ') in (' ' + s + ' ')

contains_word('the quick brown fox', 'brown')  # True
contains_word('the quick brown fox', 'row')    # False

This elegant method is also the fastest. Compared to Hugh Bothwell's and daSong's approaches:

>python -m timeit -s "def contains_word(s, w): return (' ' + w + ' ') in (' ' + s + ' ')" "contains_word('the quick brown fox', 'brown')"
1000000 loops, best of 3: 0.351 usec per loop

>python -m timeit -s "import re" -s "def contains_word(s, w): return re.compile(r'\b({0})\b'.format(w), flags=re.IGNORECASE).search(s)" "contains_word('the quick brown fox', 'brown')"
100000 loops, best of 3: 2.38 usec per loop

>python -m timeit -s "def contains_word(s, w): return s.startswith(w + ' ') or s.endswith(' ' + w) or s.find(' ' + w + ' ') != -1" "contains_word('the quick brown fox', 'brown')"
1000000 loops, best of 3: 1.13 usec per loop

Edit: A slight variant on this idea for Python 3.6+, equally fast:

def contains_word(s, w):
    return f' {w} ' in f' {s} '

Here is a very simple way to create an IP certificate that Chrome will trust.

The ssl.conf file...

[ req ]
default_bits       = 4096
distinguished_name = req_distinguished_name
req_extensions     = req_ext
prompt             = no

[ req_distinguished_name ]
commonName                  = 192.168.1.10

[ req_ext ]
subjectAltName = IP:192.168.1.10

Where, of course 192.168.1.10 is the local network IP we want Chrome to trust.

Create the certificate:

openssl genrsa -out key1.pem
openssl req -new -key key1.pem -out csr1.pem -config ssl.conf
openssl x509 -req -days 9999 -in csr1.pem -signkey key1.pem -out cert1.pem -extensions req_ext -extfile ssl.conf
rm csr1.pem

On Windows import the certificate into the Trusted Root Certificate Store on all client machines. On Android Phone or Tablet download the certificate to install it. Now Chrome will trust the certificate on windows and Android.

On windows dev box the best place to get openssl.exe is from "c:\Program Files\Git\usr\bin\openssl.exe"

A late answer, but and approach using data.table

library(data.table)
DT <- data.table(dat)

DT[, .SD[which.max(Score),], by = Group]

Or, if it is possible to have more than one equally highest score

DT[, .SD[which(Score == max(Score)),], by = Group]

Noting that (from ?data.table

.SD is a data.table containing the Subset of x's Data for each group, excluding the group column(s)

Modals always load the content into an element on the page, which more often than not is a div. Think of this div as the iframe equivalent when it comes to jQuery UI Dialogs. Now it depends on your requirements whether you want static content that resides within the page or you want to fetch the content from some other location. You may use this code and see if it works for you:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">

//modal window start
$(".example").unbind('click');
$(".example").bind('click',function(){
    showDialog();
    var titletext=$(this).attr("title");
    var openpage=$(this).attr("href");
    $("#dialog").dialog( "option", "title", titletext );
    $("#dialog").dialog( "option", "resizable", false );
    $("#dialog").dialog( "option", "buttons", { 
        "Close": function() { 
            $(this).dialog("close");
            $(this).dialog("destroy");
        } 
    });
    $("#dialog").load(openpage);
    return false;
});

//modal window end

//Modal Window Initiation start

function showDialog(){
    $("#dialog").dialog({
        height: 400,
        width: 500,
        modal: true

There are, however, a few things which you should keep in mind. You will not be able to load remote URL's on your local system, you need to upload to a server if you want to load remote URL. Even then, you may only load URL's which belong to the same domain; e.g. if you upload this file to 'www.example.com' you may only access files hosted on 'www.example.com'. For loading external links this might help. All this information you will find in the link as suggested by @Robin.

I had also faced this problem. Those time I followed some steps like:

1. File > New > Import module > select your library_project. Then include 'library_project' will be added in settings.gradle file.

2. File > Project Structure > App > Dependencies Tab > select library_project. If library_project not displaying then, Click on + button then select your library_project.

3. Clean and build your project. The following lines will be added in your app module build.gradle (hint: this is not the one where classpath is defined).

 dependencies {
     compile fileTree(dir: 'libs', include: ['*.jar'])
     compile project(':library_project')
 }

4. If these lines are not present, you must add them manually and clean and rebuild your project again (Ctrl + F9).

5. A folder named library_project will be created in your app folder.

6. If any icon or task merging error is created, go to AndroidManifest file and add <application tools:replace="icon,label,theme">

How about this?

List<string> monValues = Application["mondayValues"] as List<string>;
int sum = monValues.ConvertAll(Convert.ToInt32).Sum();

Kotlin for XML

app:cardBackgroundColor="@android:color/red"

code

cardName.setCardBackgroundColor(ContextCompat.getColor(this, R.color.colorGray));

One way of doing this is via an exists clause:

select * from genes g
where exists
(select null from genes g1
 where g.locus = g1.locus and g.chromosome = g1.chromosome and g.id <> g1.id)

Alternatively, in MySQL you can get a summary of all matching ids with a single table access, using group_concat:

select group_concat(id) matching_ids, chromosome, locus 
from genes
group by chromosome, locus
having count(*) > 1

For anyone who is still having issues after trying all the answers on this page, the following (finally) worked:

sudo apt-get install libgmp3-dev
gem install pg

It's simple. On the sender side, use Intent.putExtra:

Intent myIntent = new Intent(A.this, B.class);
myIntent.putExtra("intVariableName", intValue);
startActivity(myIntent);

On the receiver side, use Intent.getIntExtra:

 Intent mIntent = getIntent();
 int intValue = mIntent.getIntExtra("intVariableName", 0);

Of course you can use floats or doubles for "critical" things ... Many applications do nothing but crunch numbers using these datatypes.

You might have misunderstood some of the various caveats regarding floating-point numbers, such as the recommendation to never compare for exact equality, and so on.

I use following code for get different result from condition That worked for me.

Select A.column, B.column
FROM TABLE1 A
INNER JOIN
TABLE2 B
ON A.Id = (case when (your condition) then b.Id else (something) END)

Cannot resolve symbol AppCompatActivity Issue.

Do the Simple Step to resolve the problem.

i) Exit the Android studio.

ii) Go to your project directory.

iii) Find the .idea folder in your project directory.

iv) Delete .idea folder.

v) Restart your android studio.

vi) The Issue Will be resolved.

In case you would like to use timeout middleware and exclude a specific route:

var timeout = require('connect-timeout');
app.use(timeout('5s')); //set 5s timeout for all requests

app.use('/my_route', function(req, res, next) {
    req.clearTimeout(); // clear request timeout
    req.setTimeout(20000); //set a 20s timeout for this request
    next();
}).get('/my_route', function(req, res) {
    //do something that takes a long time
});

You should find that the following schema allows the what you have proposed.

  <xs:element name="foo">
    <xs:complexType>
      <xs:sequence minOccurs="0" maxOccurs="unbounded">
        <xs:choice>
          <xs:element maxOccurs="unbounded" name="child1" type="xs:unsignedByte" />
          <xs:element maxOccurs="unbounded" name="child2" type="xs:string" />
        </xs:choice>
      </xs:sequence>
    </xs:complexType>
  </xs:element>

This will allow you to create a file such as:

<?xml version="1.0" encoding="utf-8" ?>
<foo>
  <child1>2</child1>
  <child1>3</child1>
  <child2>test</child2>
  <child2>another-test</child2>
</foo>

Which seems to match your question.

The assertNotNull() method means "a passed parameter must not be null": if it is null then the test case fails.
The assertNull() method means "a passed parameter must be null": if it is not null then the test case fails.

String str1 = null;
String str2 = "hello";              

// Success.
assertNotNull(str2);

// Fail.
assertNotNull(str1);

// Success.
assertNull(str1);

// Fail.
assertNull(str2);

There are two best contenders:

1. Create a 1×1 image data, set the color, and putImageData at the location:

   var id = myContext.createImageData(1,1); // only do this once per page
   var d  = id.data;                        // only do this once per page
   d[0]   = r;
   d[1]   = g;
   d[2]   = b;
   d[3]   = a;
   myContext.putImageData( id, x, y );     
   

2. Use fillRect() to draw a pixel (there should be no aliasing issues):

   ctx.fillStyle = "rgba("+r+","+g+","+b+","+(a/255)+")";
   ctx.fillRect( x, y, 1, 1 );
   

You can test the speed of these here: http://jsperf.com/setting-canvas-pixel/9 or here https://www.measurethat.net/Benchmarks/Show/1664/1

I recommend testing against browsers you care about for maximum speed. As of July 2017, fillRect() is 5-6× faster on Firefox v54 and Chrome v59 (Win7x64).

Other, sillier alternatives are:

• using getImageData()/putImageData() on the entire canvas; this is about 100× slower than other options.

• creating a custom image using a data url and using drawImage() to show it:

  var img = new Image;
  img.src = "data:image/png;base64," + myPNGEncoder(r,g,b,a);
  // Writing the PNGEncoder is left as an exercise for the reader
  

• creating another img or canvas filled with all the pixels you want and use drawImage() to blit just the pixel you want across. This would probably be very fast, but has the limitation that you need to pre-calculate the pixels you need.

Note that my tests do not attempt to save and restore the canvas context fillStyle; this would slow down the fillRect() performance. Also note that I am not starting with a clean slate or testing the exact same set of pixels for each test.

The range(n) in python returns from 0 to n-1. Respectively, the range(1,n) from 1 to n-1. So, if you want to omit the first value and get also the last value (n) you can do it very simply using the following code.

for i in range(1, n + 1):
        print(i) #prints from 1 to n

brew install wget

Homebrew is a package manager for OSX analogous to yum, apt-get, choco, emerge, etc. Be aware that you will also need to install Xcode and the Command Line Tools. Virtually anyone who uses the command line in OSX will want to install these things anyway.

If you can't or don't want to use homebrew, you could also:

Install wget manually:

curl -# "http://ftp.gnu.org/gnu/wget/wget-1.17.1.tar.xz" -o "wget.tar.xz"
tar xf wget.tar.xz
cd wget-1.17.1
./configure --with-ssl=openssl -with-libssl-prefix=/usr/local/ssl && make -j8 && make install

Or, use a bash alias:

function _wget() { curl "${1}" -o $(basename "${1}") ; };
alias wget='_wget'

I use this script: https://github.com/maksimr/vim-jsbeautify

In the above link you have all the info:

1. Install
2. Configure (copy from the first example)
3. Run :call HtmlBeautify()

Does the job beautifully!

There are multiple settings for adjusting the legend size. The two I find most useful are:

• labelspacing: which sets the spacing between label entries in multiples of the font size. For instance with a 10 point font, legend(..., labelspacing=0.2) will reduce the spacing between entries to 2 points. The default on my install is about 0.5.
• prop: which allows full control of the font size, etc. You can set an 8 point font using legend(..., prop={'size':8}). The default on my install is about 14 points.

In addition, the legend documentation lists a number of other padding and spacing parameters including: borderpad, handlelength, handletextpad, borderaxespad, and columnspacing. These all follow the same form as labelspacing and area also in multiples of fontsize.

These values can also be set as the defaults for all figures using the matplotlibrc file.

I just saw this test:

bool getFileExists(const TCHAR *file)
{ 
  return (GetFileAttributes(file) != 0xFFFFFFFF);
}

I'm using the environment variable COMPUTERNAME:

copy "C:\Program Files\Windows Resource Kits\Tools\" %SYSTEMROOT%\system32
srvcheck \\%COMPUTERNAME% > c:\shares.txt
echo %COMPUTERNAME%

I have found the only reliable, portable method to be

bytes(bytearray([n]))

Just bytes([n]) does not work in python 2. Taking the scenic route through bytearray seems like the only reasonable solution.

You may need to declare the radio buttons in the onCreate method of your code and use them.

RadioButton rb1 = (RadioButton) findViewById(R.id.option1);
rb1.setChecked(true);

map.at("key") throws exception if missing key

If k does not match the key of any element in the container, the function throws an out_of_range exception.

http://www.cplusplus.com/reference/map/map/at/

One way to solve this problem is to get the starting points from the values themselves:

var minLen, maxLen uint
if len(sliceOfThings) > 0 {
  minLen = sliceOfThings[0].minLen
  maxLen = sliceOfThings[0].maxLen
  for _, thing := range sliceOfThings[1:] {
    if minLen > thing.minLen { minLen = thing.minLen }
    if maxLen < thing.maxLen { maxLen = thing.maxLen }
  }
}

Yes. IMHO, overriding GetWebRequest() is the best solution to WebClient's limited functionalty. Before I knew about this option, I wrote lots of really painful code at the HttpWebRequest layer because WebClient almost, but not quite, did what I needed. Derivation is much easier.

Another option is to use the regular WebClient class, but manually populate the Cookie header before making the request and then pull out the Set-Cookies header on the response. There are helper methods on the CookieContainer class which make creating and parsing these headers easier: CookieContainer.SetCookies() and CookieContainer.GetCookieHeader(), respectively.

I prefer the former approach since it's easier for the caller and requires less repetitive code than the second option. Also, the derivation approach works the same way for multiple extensibility scenarios (e.g. cookies, proxies, etc.).

You can simply do:

"123456".Select(q => new string(q,1)).ToArray();

to have an enumerable of integers, as per comment request, you can:

"123456".Select(q => int.Parse(new string(q,1))).ToArray();

It is a little weak since it assumes the string actually contains numbers.

The best way for DateTime is use a Trigger:

/************ ROLE ************/
drop table if exists `role`;
create table `role` (
    `id_role` bigint(20) unsigned not null auto_increment,
    `date_created` datetime,
    `date_deleted` datetime,
    `name` varchar(35) not null,
    `description` text,
    primary key (`id_role`)
) comment='';

drop trigger if exists `role_date_created`;
create trigger `role_date_created` before insert
    on `role`
    for each row 
    set new.`date_created` = now();

YOu can also rewrite it like this

FROM Resource r WHERE r.ResourceNo IN
        ( 
            SELECT m.ResourceNo FROM JobMember m
            JOIN Job j ON j.JobNo = m.JobNo
            WHERE j.ProjectManagerNo = @UserResourceNo 
            OR
            j.AlternateProjectManagerNo = @UserResourceNo

            Union All

            SELECT m.ResourceNo FROM JobMember m
            JOIN JobTask t ON t.JobTaskNo = m.JobTaskNo
            WHERE t.TaskManagerNo = @UserResourceNo
            OR
            t.AlternateTaskManagerNo = @UserResourceNo

        )

Also a return table is expected in your RETURN statement

You can use a list comprehension to filter it:

j2 = [i for i in j if i >= 5]

If you actually want it sorted like your example was, you can use sorted:

j2 = sorted(i for i in j if i >= 5)

or call sort on the final list:

j2 = [i for i in j if i >= 5]
j2.sort()

I think it's a little simpler to use the dplyr functions select and left_join ; at least it's easier for me to understand. The join function from dplyr are made to mimic sql arguments.

 library(tidyverse)

 DF2 <- DF2 %>%
   select(client, LO)

 joined_data <- left_join(DF1, DF2, by = "Client")

You don't actually need to use the "by" argument in this case because the columns have the same name.

As the others already mentioned: the division operator is / rather than **. If you wanna print the ** character within a string you have to escape it:

print("foo \\")
# will print: foo \

I think to print the string you wanted I think you gonna need this code:

print("Length between sides: " + str((length*length)*2.6) + " \\ 1.5 = " + str(((length*length)*2.6)/1.5) + " Units")

And this one is a more readable version of the above (using the format method):

message = "Length between sides: {0} \\ 1.5 = {1} Units"
val1 = (length * length) * 2.6
val2 = ((length * length) * 2.6) / 1.5
print(message.format(val1, val2))

When you are not sure of the number of rows, then you can do it this way:

followers_df.index = range(len(followers_df))

Look at DATEADD

SELECT DATEADD(mm, 1, OrderDate)AS TimeFrame

Here's the MSDN

In your case

...WHERE reference_dt = DATEADD(MM,1, myColDate)

you might want to start with max(trans_seq_no) + 1.

watch:

SQL> create table my_numbers(my_number number not null primary key);

Table created.

SQL> insert into my_numbers(select rownum from user_objects);

260 rows created.

SQL> select max(my_number) from my_numbers;

MAX(MY_NUMBER)
--------------
           260

SQL> create sequence my_number_sn start with 260;

Sequence created.

SQL> insert into my_numbers(my_number) values (my_number_sn.NEXTVAL);
insert into my_numbers(my_number) values (my_number_sn.NEXTVAL)
*
ERROR at line 1:
ORA-00001: unique constraint (NEIL.SYS_C00102439) violated

When you create a sequence with a number, you have to remember that the first time you select against the sequence, Oracle will return the initial value that you assigned it.

SQL> drop sequence my_number_sn;

Sequence dropped.

SQL> create sequence my_number_sn start with 261;

Sequence created.

SQL>  insert into my_numbers(my_number) values (my_number_sn.NEXTVAL);

1 row created.

If you're trying to do the 'gapless' thing, I strongly advise you to

1 not do it, and #2 not use a sequence for it.

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.

In this sample in catch block i change the value of counter and it will break while block:

class TestBreak {
    public static void main(String[] a) {
        int counter = 0;

        while(counter<5) {
            try {
                counter++;
                int x = counter/0;
            }
            catch(Exception e) {
                counter = 1000;    
            }
        }
    }
}k

You could do:

import inspect

mydict = {'one': 1, 'two': 2}

source = inspect.getsourcelines(inspect.getmodule(inspect.stack()[0][0]))[0]
print [x for x in source if x.startswith("mydict = ")]

Also: make sure not to shadow the dict builtin!

SELECT TIMESTAMPDIFF (YEAR, YOUR_COLUMN, CURDATE()) FROM YOUR_TABLE AS AGE

Click for demo..

Simple but elegant..

You can also try this

Private Declare Function GetWindowText Lib "user32.dll" (ByVal hwnd As IntPtr, ByVal lpString As StringBuilder, ByVal cch As Integer) As Integer

I always use Declare Function instead of DllImport... Its more simply, its shorter and does the same

I would go this way:

using GalaSoft.MvvmLight;
using GalaSoft.MvvmLight.Command;    
using GalaSoft.MvvmLight.Messaging; 

// View

public partial class TestCloseWindow : Window
{
    public TestCloseWindow() {
        InitializeComponent();
        Messenger.Default.Register<CloseWindowMsg>(this, (msg) => Close());
    }
}

// View Model

public class MainViewModel: ViewModelBase
{
    ICommand _closeChildWindowCommand;

    public ICommand CloseChildWindowCommand {
        get {
            return _closeChildWindowCommand?? (_closeChildWindowCommand = new RelayCommand(() => {
                Messenger.Default.Send(new CloseWindowMsg());
        }));
        }
    }
}

public class CloseWindowMsg
{
}

Place your assets in public directory and use the following

URL::to()

example

<link rel="stylesheet" type="text/css" href="{{ URL::to('css/style.css') }}">
<script type="text/javascript" src="{{ URL::to('js/jquery.min.js') }}"></script>

I have this function in the document ready event so that the reCaptcha is dynamically sized. Anyone should be able to drop this in place and go.

function ScaleReCaptcha()
{
if (document.getElementsByClassName('g-recaptcha').length > 0)
{parentWidth = document.getElementsByClassName('g-recaptcha') [0].parentNode.clientWidth;
         childWidth = document.getElementsByClassName('g-recaptcha')[0].firstChild.clientWidth;
         scale = (parentWidth) / (childWidth);
         new_width = childWidth * scale;
         document.getElementsByClassName('g-recaptcha')[0].style.transform = 'scale(' + scale + ')';
         document.getElementsByClassName('g-recaptcha')[0].style.transformOrigin = '0 0';
     }
}

As @KaptajnKold had answered

var x = [ 'p0', 'p1', 'p2' ];
call_me.apply(this, x);

And you don't need to define every parameters for call_me function either. You can just use arguments

function call_me () {
    // arguments is a array consisting of params.
    // arguments[0] == 'p0',
    // arguments[1] == 'p1',
    // arguments[2] == 'p2'
}

While you can use a virtualenv, you don't need to. The trick is passing the PEP370 --user argument to the setup.py script. With the latest version of pip, one way to do it is:

pip install --user mercurial

This should result in the hg script being installed in $HOME/.local/bin/hg and the rest of the hg package in $HOME/.local/lib/pythonx.y/site-packages/.

Note, that the above is true for Python 2.6. There has been a bit of controversy among the Python core developers about what is the appropriate directory location on Mac OS X for PEP370-style user installations. In Python 2.7 and 3.2, the location on Mac OS X was changed from $HOME/.local to $HOME/Library/Python. This might change in a future release. But, for now, on 2.7 (and 3.2, if hg were supported on Python 3), the above locations will be $HOME/Library/Python/x.y/bin/hg and $HOME/Library/Python/x.y/lib/python/site-packages.

Similar behavior exists when module attribute names begin with a single underscore (e.g. _foo).

Module attributes named as such will not be copied into an importing module when using the from* method, e.g.:

from bar import *

However, this is a convention and not a language constraint. These are not private attributes; they can be referenced and manipulated by any importer. Some argue that because of this, Python can not implement true encapsulation.

It should be noted that the documentation recommends using a Layout rather than Canvas.drawText directly. My full answer about using a StaticLayout is here, but I will provide a summary below.

String text = "This is some text.";

TextPaint textPaint = new TextPaint();
textPaint.setAntiAlias(true);
textPaint.setTextSize(16 * getResources().getDisplayMetrics().density);
textPaint.setColor(0xFF000000);

int width = (int) textPaint.measureText(text);
StaticLayout staticLayout = new StaticLayout(text, textPaint, (int) width, Layout.Alignment.ALIGN_NORMAL, 1.0f, 0, false);
staticLayout.draw(canvas);

Here is a fuller example in the context of a custom view:

public class MyView extends View {

    String mText = "This is some text.";
    TextPaint mTextPaint;
    StaticLayout mStaticLayout;

    // use this constructor if creating MyView programmatically
    public MyView(Context context) {
        super(context);
        initLabelView();
    }

    // this constructor is used when created from xml
    public MyView(Context context, AttributeSet attrs) {
        super(context, attrs);
        initLabelView();
    }

    private void initLabelView() {
        mTextPaint = new TextPaint();
        mTextPaint.setAntiAlias(true);
        mTextPaint.setTextSize(16 * getResources().getDisplayMetrics().density);
        mTextPaint.setColor(0xFF000000);

        // default to a single line of text
        int width = (int) mTextPaint.measureText(mText);
        mStaticLayout = new StaticLayout(mText, mTextPaint, (int) width, Layout.Alignment.ALIGN_NORMAL, 1.0f, 0, false);

        // New API alternate
        //
        // StaticLayout.Builder builder = StaticLayout.Builder.obtain(mText, 0, mText.length(), mTextPaint, width)
        //        .setAlignment(Layout.Alignment.ALIGN_NORMAL)
        //        .setLineSpacing(1, 0) // multiplier, add
        //        .setIncludePad(false);
        // mStaticLayout = builder.build();
    }

    @Override
    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
        // Tell the parent layout how big this view would like to be
        // but still respect any requirements (measure specs) that are passed down.

        // determine the width
        int width;
        int widthMode = MeasureSpec.getMode(widthMeasureSpec);
        int widthRequirement = MeasureSpec.getSize(widthMeasureSpec);
        if (widthMode == MeasureSpec.EXACTLY) {
            width = widthRequirement;
        } else {
            width = mStaticLayout.getWidth() + getPaddingLeft() + getPaddingRight();
            if (widthMode == MeasureSpec.AT_MOST) {
                if (width > widthRequirement) {
                    width = widthRequirement;
                    // too long for a single line so relayout as multiline
                    mStaticLayout = new StaticLayout(mText, mTextPaint, width, Layout.Alignment.ALIGN_NORMAL, 1.0f, 0, false);
                }
            }
        }

        // determine the height
        int height;
        int heightMode = MeasureSpec.getMode(heightMeasureSpec);
        int heightRequirement = MeasureSpec.getSize(heightMeasureSpec);
        if (heightMode == MeasureSpec.EXACTLY) {
            height = heightRequirement;
        } else {
            height = mStaticLayout.getHeight() + getPaddingTop() + getPaddingBottom();
            if (heightMode == MeasureSpec.AT_MOST) {
                height = Math.min(height, heightRequirement);
            }
        }

        // Required call: set width and height
        setMeasuredDimension(width, height);
    }

    @Override
    protected void onDraw(Canvas canvas) {
        super.onDraw(canvas);
        // do as little as possible inside onDraw to improve performance

        // draw the text on the canvas after adjusting for padding
        canvas.save();
        canvas.translate(getPaddingLeft(), getPaddingTop());
        mStaticLayout.draw(canvas);
        canvas.restore();
    }
}

Neither above helped me, instead, I connected my phone through the back USB hubs (I used forward USB hubs previously), and this helped me!

HTML:

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

JS:

document.getElementById("log").innerHTML="WHATEVER YOU WANT...";

import datetime

def utc_str_to_local_str(utc_str: str, utc_format: str, local_format: str):
    """
    :param utc_str: UTC time string
    :param utc_format: format of UTC time string
    :param local_format: format of local time string
    :return: local time string
    """
    temp1 = datetime.datetime.strptime(utc_str, utc_format)
    temp2 = temp1.replace(tzinfo=datetime.timezone.utc)
    local_time = temp2.astimezone()
    return local_time.strftime(local_format)

utc = '2018-10-17T00:00:00.111Z'
utc_fmt = '%Y-%m-%dT%H:%M:%S.%fZ'
local_fmt = '%Y-%m-%dT%H:%M:%S+08:00'
local_string = utc_str_to_local_str(utc, utc_fmt, local_fmt)
print(local_string)   # 2018-10-17T08:00:00+08:00

for example, my timezone is '+08:00'. input utc = 2018-10-17T00:00:00.111Z, then I will get output = 2018-10-17T08:00:00+08:00

I figured out myself.

cmp calls ComputeBetasAndNuHat which returns a list which has objective as minusloglik

So I can change the function cmp to get this value.

In my case
Make sure your (test package name) of YourApplicationTests is equivalent to the (main package name).

$ git clone --mirror $URL

is a short-hand for

$ git clone --bare $URL
$ (cd $(basename $URL) && git remote add --mirror=fetch origin $URL)

(Copied directly from here)

How the current man-page puts it:

Compared to --bare, --mirror not only maps local branches of the source to local branches of the target, it maps all refs (including remote branches, notes etc.) and sets up a refspec configuration such that all these refs are overwritten by a git remote update in the target repository.

An enum is nearly an integer. To simplify a lot

enum yourenum { a, b, c };

is almost like

#define a 0
#define b 1
#define c 2

Of course, it is not really true. I'm trying to explain that enum are some kind of coding...

This one worked for me (just keep it for reference when in need)

# Go into your existing directory and run below commands
cd docker-spring-boot
echo "# docker-spring-boot" >> README.md
git init
git add -A
git commit -m "first commit"
git branch -M master
git remote add origin https://github.com/devopsmaster/docker-spring-boot.git
git push -u origin master
                

Use >> to append:

command >> file

You can tell it's playing using:

AVPlayer *player = ...
if ((player.rate != 0) && (player.error == nil)) {
    // player is playing
}

Swift 3 extension:

extension AVPlayer {
    var isPlaying: Bool {
        return rate != 0 && error == nil
    }
}

For multiple elements, you should give it a class rather than id eg:

<input type="text" class="task" name="task[]" />

Now you can get those using jquery something like this:

$('.task').each(function(){
   alert($(this).val());
});

For Retrofit retrofit:2.0.0-beta4 the code goes as follows:

OkHttpClient client = new OkHttpClient.Builder()
    .addInterceptor(logging)
    .connectTimeout(30, TimeUnit.SECONDS)
    .readTimeout(30, TimeUnit.SECONDS)
    .writeTimeout(30, TimeUnit.SECONDS)
    .build();

Retrofit retrofit = new Retrofit.Builder()
    .baseUrl("http://api.yourapp.com/")
    .addConverterFactory(GsonConverterFactory.create())
    .client(client)
    .build();

String a = "..."; 
String b = "...";  

int compare = a.compareTo(b);  

if (compare < 0) {  
    //a is smaller
}
else if (compare > 0) {
    //a is larger 
}
else {  
    //a is equal to b
} 

Okay, there are a lot of people here saying, "yes" and "yes, but it will be hard" so I'll differ.

No.

The problem isn't "learning Java" in 10 weeks, because I think that by the time 10 weeks is up, you'll be able to program some things and have an idea of what to do to solve some simple things.

But that won't make you ready for a J2ME fast track course. Fast track courses tend to be for people that have a strong background in the prerequisites. You might be able to do many of the things as you are going along, but without the background to understand the why of what you're doing, it will seem like a lot of semi-random things to memorize by rote, and will likely quickly vanish.

Basically, I think it just takes time: time to let lessons sink in, time to experiment and fail a few times so that the why suddenly jumps out at you...

Ultimately, I suspect that you could get through it, but that you would not end up being very proficent at all. (the final two paragraphs of Uri's post say it all.)

I don't want to be a complete downer, and I definitely hope you do well and succeed...but I would hate to bet money on it.

(Understand, I don't know you from Adam...so I'm making statements based on my experience with how it was for me, and people I've worked with...so this isn't a slight against you...just an observation that this is a very big meal you're setting down to eat.)

The following illustrates the solution, assign your string to a variable pointer to a constant array of char (a string is a constant pointer to a constant array of char - plus length info):

#include <iostream>

void Swap(const char * & left, const char * & right) {
    const char *const temp = left;
    left = right;
    right = temp;
}

int main() {
    const char * x = "Hello"; // These works because you are making a variable
    const char * y = "World"; // pointer to a constant string
    std::cout << "x = " << x << ", y = " << y << '\n';
    Swap(x, y);
    std::cout << "x = " << x << ", y = " << y << '\n';
}

I'd have to recommend NumPy as well

Not only is it faster for doing vector math, but it also has a ton of convenience functions.

If you want something even faster for 1d vectors, try vop

It's similar to MatLab, but free and stuff. Here's an example of what you'd do

from numpy import matrix
a = matrix((2,2,2))
b = matrix((1,1,1))
ret = a - b
print ret
>> [[1 1 1]]

Boom.

Just push to the branch that the pull request references. As long as the pull request is still open, it should get updated with any added commits automatically.

i was facing same problem while copying form source directory to destination

source directory had files ~3 lakcs

i used cp with option -r and it's worked for me

cp -r abc/ def/

it will copy all files from abc to def without giving warning of Argument list too long

After stripping all characters except '+' and digits from your input, this should do it:

^\+[1-9]{1}[0-9]{3,14}$

If you want to be more exact with the country codes see this question on List of phone number country codes

However, I would try to be not too strict with my validation. Users get very frustrated if they are told their valid numbers are not acceptable.

Here are a few ways to create a list with N of continuous natural numbers starting from 1.

1 range:

def numbers(n): 
    return range(1, n+1);

2 List Comprehensions:

def numbers(n):
    return [i for i in range(1, n+1)]

You may want to look into the method xrange and the concepts of generators, those are fun in python. Good luck with your Learning!

DAO and Repository pattern are ways of implementing Data Access Layer (DAL). So, let's start with DAL, first.

Object-oriented applications that access a database, must have some logic to handle database access. In order to keep the code clean and modular, it is recommended that database access logic should be isolated into a separate module. In layered architecture, this module is DAL.

So far, we haven't talked about any particular implementation: only a general principle that putting database access logic in a separate module.

Now, how we can implement this principle? Well, one know way of implementing this, in particular with frameworks like Hibernate, is the DAO pattern.

DAO pattern is a way of generating DAL, where typically, each domain entity has its own DAO. For example, User and UserDao, Appointment and AppointmentDao, etc. An example of DAO with Hibernate: http://gochev.blogspot.ca/2009/08/hibernate-generic-dao.html.

Then what is Repository pattern? Like DAO, Repository pattern is also a way achieving DAL. The main point in Repository pattern is that, from the client/user perspective, it should look or behave as a collection. What is meant by behaving like a collection is not that it has to be instantiated like Collection collection = new SomeCollection(). Instead, it means that it should support operations such as add, remove, contains, etc. This is the essence of Repository pattern.

In practice, for example in the case of using Hibernate, Repository pattern is realized with DAO. That is an instance of DAL can be both at the same an instance of DAO pattern and Repository pattern.

Repository pattern is not necessarily something that one builds on top of DAO (as some may suggest). If DAOs are designed with an interface that supports the above-mentioned operations, then it is an instance of Repository pattern. Think about it, If DAOs already provide a collection-like set of operations, then what is the need for an extra layer on top of it?

In format function your can use timestamp_format function. Example, if the format is YYYYMMDD you can do it :

select TIMESTAMP_FORMAT(yourcolumnchar, 'YYYYMMDD') as YouTimeStamp 
from yourtable

you can then adapt then format with elements format foundable here

Official document of Crypto++ AES is a good start. And from my archive, a basic implementation of AES is as follows:

Please refer here with more explanation, I recommend you first understand the algorithm and then try to understand each line step by step.

#include <iostream>
#include <iomanip>

#include "modes.h"
#include "aes.h"
#include "filters.h"

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

    //Key and IV setup
    //AES encryption uses a secret key of a variable length (128-bit, 196-bit or 256-   
    //bit). This key is secretly exchanged between two parties before communication   
    //begins. DEFAULT_KEYLENGTH= 16 bytes
    CryptoPP::byte key[ CryptoPP::AES::DEFAULT_KEYLENGTH ], iv[ CryptoPP::AES::BLOCKSIZE ];
    memset( key, 0x00, CryptoPP::AES::DEFAULT_KEYLENGTH );
    memset( iv, 0x00, CryptoPP::AES::BLOCKSIZE );

    //

    stfEncryptor.Put( reinterpret_cast<const unsigned char*>( plaintext.c_str() ), plaintext.length() );
    stfEncryptor.MessageEnd();

    //
    std::cout << "Cipher Text (" << ciphertext.size() << " bytes)" << std::endl;

    for( int i = 0; i < ciphertext.size(); i++ ) {

        std::cout << "0x" << std::hex << (0xFF & static_cast<CryptoPP::byte>(ciphertext[i])) << " ";
    }

    std::cout << std::endl << std::endl;

    CryptoPP::CBC_Mode_ExternalCipher::Decryption cbcDecryption( aesDecryption, iv );

    CryptoPP::StreamTransformationFilter stfDecryptor(cbcDecryption, new CryptoPP::StringSink( decryptedtext ) );
    stfDecryptor.Put( reinterpret_cast<const unsigned char*>( ciphertext.c_str() ), ciphertext.size() );
    stfDecryptor.MessageEnd();

    //
    // Dump Decrypted Text
    //
    std::cout << "Decrypted Text: " << std::endl;
    std::cout << decryptedtext;
    std::cout << std::endl << std::endl;

TL;DR

Just returning response()->json($promotion) won't solve the issue in this question. $promotion is an Eloquent object, which Laravel will automatically json_encode for the response. The json encoding is failing because of the img property, which is a PHP stream resource, and cannot be encoded.

Details

Whatever you return from your controller, Laravel is going to attempt to convert to a string. When you return an object, the object's __toString() magic method will be invoked to make the conversion.

Therefore, when you just return $promotion from your controller action, Laravel is going to call __toString() on it to convert it to a string to display.

On the Model, __toString() calls toJson(), which returns the result of json_encode. Therefore, json_encode is returning false, meaning it is running into an error.

Your dd shows that your img attribute is a stream resource. json_encode cannot encode a resource, so this is probably causing the failure. You should add your img attribute to the $hidden property to remove it from the json_encode.

class Promotion extends Model
{
    protected $hidden = ['img'];

    // rest of class
}

There're several open-source libraries which allow console table formatting, ranging from simple (like the code samples in the answers here) to more advanced.

ConsoleTable

Judging by NuGet stats, the most popular library for formatting tables is ConsoleTable. Tables are constructed like this (from the readme file):

var table = new ConsoleTable("one", "two", "three");
table.AddRow(1, 2, 3)
     .AddRow("this line should be longer", "yes it is", "oh");

Tables can be formatted using one of the predefined styles. It'll look like this:

--------------------------------------------------
| one                        | two       | three |
--------------------------------------------------
| 1                          | 2         | 3     |
--------------------------------------------------
| this line should be longer | yes it is | oh    |
--------------------------------------------------

This library expects single-line cells with no formatting.

There're a couple of libraries based on ConsoleTable with slightly extended feature sets, like more line styles.

CsConsoleFormat

If you need more complex formatting, you can use CsConsoleFormat.† Here's a table generated from a process list (from a sample project):

new Grid { Stroke = StrokeHeader, StrokeColor = DarkGray }
    .AddColumns(
        new Column { Width = GridLength.Auto },
        new Column { Width = GridLength.Auto, MaxWidth = 20 },
        new Column { Width = GridLength.Star(1) },
        new Column { Width = GridLength.Auto }
    )
    .AddChildren(
        new Cell { Stroke = StrokeHeader, Color = White }
            .AddChildren("Id"),
        new Cell { Stroke = StrokeHeader, Color = White }
            .AddChildren("Name"),
        new Cell { Stroke = StrokeHeader, Color = White }
            .AddChildren("Main Window Title"),
        new Cell { Stroke = StrokeHeader, Color = White }
            .AddChildren("Private Memory"),
        processes.Select(process => new[] {
            new Cell { Stroke = StrokeRight }
                .AddChildren(process.Id),
            new Cell { Stroke = StrokeRight, Color = Yellow, TextWrap = TextWrapping.NoWrap }
                .AddChildren(process.ProcessName),
            new Cell { Stroke = StrokeRight, Color = White, TextWrap = TextWrapping.NoWrap }
                .AddChildren(process.MainWindowTitle),
            new Cell { Stroke = LineThickness.None, Align = HorizontalAlignment.Right }
                .AddChildren(process.PrivateMemorySize64.ToString("n0")),
        })
    )

The end result will look like this:

It supports any kind of table lines (several included and customizable), multi-line cells with word wrap, colors, columns growing based on content or percentage, text alignment etc.

_{† CsConsoleFormat was developed by me.}

The DataTable has a collection .Rows of DataRow elements.

Each DataRow corresponds to one row in your database, and contains a collection of columns.

In order to access a single value, do something like this:

 foreach(DataRow row in YourDataTable.Rows)
 { 
     string name = row["name"].ToString();
     string description = row["description"].ToString();
     string icoFileName = row["iconFile"].ToString();
     string installScript = row["installScript"].ToString();
 }

Use getattr to get an attribute from a name in a string. In other words, get the instance as

instance = getattr(modul, class_name)()

Have just attempted this fix with 5.3.3 and there's no change. Googling around I found this web page http://anothersysadmin.wordpress.com/2012/02/16/php-5-3-max_input_vars-and-big-forms/ detailing other settings which need changing if your server uses the Suhosin patch which Apache under Debian does.

The site explains:

So, if you want to increase this number to, say, 3000 from the default number which is 1000, you have to put in your php.ini these lines:

max_input_vars = 3000 suhosin.post.max_vars = 3000 suhosin.request.max_vars = 3000

I tested it (added settings to php.ini both in /etc/php5/apache2 and /etc/php5/cli, and restarted Apache successfully) but still no max_input_vars variable in phpinfo.

A few sites point to PHP 5.3.9 as the first PHP version in which this change will take, so my fault for not RTM properly in the first place, although I'm interested to see people reporting it working in version above 5.3.3 but below 5.3.9.

Regarding this answer, the snapshot function is deprecated in version 3.6, according to this update. So, on version 3.6 and above, it is possible to perform the operation this way:

db.person.find().forEach(
    function (elem) {
        db.person.update(
            {
                _id: elem._id
            },
            {
                $set: {
                    name: elem.firstname + ' ' + elem.lastname
                }
            }
        );
    }
);

If support for the iPad 2 or iPod Touch is important for your application, I'd choose a barcode scanner SDK that can decode barcodes in blurry images, such as our Scandit barcode scanner SDK for iOS and Android. Decoding blurry barcode images is also helpful on phones with autofocus cameras because the user does not have to wait for the autofocus to kick in.

Scandit comes with a free community price plan and also has a product API that makes it easy to convert barcode numbers into product names.

(Disclaimer: I'm a co-founder of Scandit)

For performance, it usually best to make the code as simple and clear as possible and this will often perform well (as the JIT will optimise this code best). In your case, the simplest examples are also likely to be the fastest.

I would do either

int cmp = a > b ? +1 : a < b ? -1 : 0;

or a longer version

int cmp;
if (a > b)
   cmp = +1;
else if (a < b)
   cmp = -1;
else
   cmp = 0;

or

int cmp = Integer.compare(a, b); // in Java 7
int cmp = Double.compare(a, b); // before Java 7

It's best not to create an object if you don't need to.

Performance wise, the first is best.

If you know for sure that you won't get an overflow you can use

int cmp = a - b; // if you know there wont be an overflow.

you won't get faster than this.

header("Content-Type: text/html; charset=utf8");
$url  = simplexml_load_file("http://URI.com");

 foreach ($url->PRODUCT as $product) {  
    foreach($urun->attributes() as $k => $v) {
        echo $k." : ".$v.' <br />';
    }
    echo '<hr/>';
}

Obviously, you'll need a rooted android device. Then set up an FTP server and transfer the files.

You can simply make the start_date required using

<input type="submit" value="Submit" required />

You don't even need the checkform() then.

You can give a try to my jQuery plugin, FixTo.

Usage:

$('#mydiv').fixTo('#centeredContainer');

Here is a simple way using an ArrayList:

List<Integer> solution = new ArrayList<>();
for (int i = 1; i <= 6; i++) {
    solution.add(i);
}
Collections.shuffle(solution);

First option (bad because of throw-catch, but MS will do work for you):

bool IsValidEmail(string email)

    try {
        var mail = new System.Net.Mail.MailAddress(email);
        return true;
    }
    catch {
        return false;
    }
}

Second option is read I Knew How To Validate An Email Address Until I Read The RFC and RFC specification

if [[ $(ls -A | head -c1 | wc -c) -ne 0 ]]; then ...; fi

Thanks to netj for a suggestion to improve my original:
if [[ $(ls -A | wc -c) -ne 0 ]]; then ...; fi

This is an old question but I see at least two things that need some improvement or at least some clarification.

First problem

First problem I see is that most of the examples provided here simply don't work. They use the ls -al and ls -Al commands - both of which output non-empty strings in empty directories. Those examples always report that there are files even when there are none.

For that reason you should use just ls -A - Why would anyone want to use the -l switch which means "use a long listing format" when all you want is test if there is any output or not, anyway?

So most of the answers here are simply incorrect.

Second problem

The second problem is that while some answers work fine (those that don't use ls -al or ls -Al but ls -A instead) they all do something like this:

1. run a command
2. buffer its entire output in RAM
3. convert the output into a huge single-line string
4. compare that string to an empty string

What I would suggest doing instead would be:

1. run a command
2. count the characters in its output without storing them
   • or even better - count the number of maximally 1 character using head -c1
     (thanks to netj for posting this idea in the comments below)
3. compare that number with zero

So for example, instead of:

if [[ $(ls -A) ]]

I would use:

if [[ $(ls -A | wc -c) -ne 0 ]]
# or:
if [[ $(ls -A | head -c1 | wc -c) -ne 0 ]]

Instead of:

if [ -z "$(ls -lA)" ]

I would use:

if [ $(ls -lA | wc -c) -eq 0 ]
# or:
if [ $(ls -lA | head -c1 | wc -c) -eq 0 ]

and so on.

For small outputs it may not be a problem but for larger outputs the difference may be significant:

$ time [ -z "$(seq 1 10000000)" ]

real    0m2.703s
user    0m2.485s
sys 0m0.347s

Compare it with:

$ time [ $(seq 1 10000000 | wc -c) -eq 0 ]

real    0m0.128s
user    0m0.081s
sys 0m0.105s

And even better:

$ time [ $(seq 1 10000000 | head -c1 | wc -c) -eq 0 ]

real    0m0.004s
user    0m0.000s
sys 0m0.007s

Full example

Updated example from the answer by Will Vousden:

if [[ $(ls -A | wc -c) -ne 0 ]]; then
    echo "there are files"
else
    echo "no files found"
fi

Updated again after suggestions by netj:

if [[ $(ls -A | head -c1 | wc -c) -ne 0 ]]; then
    echo "there are files"
else
    echo "no files found"
fi

Additional update by jakeonfire:

grep will exit with a failure if there is no match. We can take advantage of this to simplify the syntax slightly:

if ls -A | head -c1 | grep -E '.'; then
    echo "there are files"
fi

if ! ls -A | head -c1 | grep -E '.'; then
    echo "no files found"
fi

Discarding whitespace

If the command that you're testing could output some whitespace that you want to treat as an empty string, then instead of:

| wc -c

you could use:

| tr -d ' \n\r\t ' | wc -c

or with head -c1:

| tr -d ' \n\r\t ' | head -c1 | wc -c

or something like that.

Summary

1. First, use a command that works.

2. Second, avoid unnecessary storing in RAM and processing of potentially huge data.

The answer didn't specify that the output is always small so a possibility of large output needs to be considered as well.

I tried with gcc and come up with for my need I was forced to use the last alternative, to compile with out error.

typedef enum state {a = 0, b = 1, c = 2} state;

typedef enum state {a = 0, b = 1, c = 2} state;

typedef enum state old; // New type, alias of the state type.
typedef enum state new; // New type, alias of the state type.

new now     = a;
old before  = b;

printf("State   now = %d \n", now);
printf("Sate before = %d \n\n", before);

Based on @brettdj's answer using a VBScript regex ojbect with two modifications:

• The function handles variants and returns a variant. That is, to take care of a null case; and
• Uses explicit object creation, with a reference to the "Microsoft VBScript Regular Expressions 5.5" library

Function GetDigitsInVariant(inputVariant As Variant) As Variant
  ' Returns:
  '     Only the digits found in a varaint.
  ' Examples:
  '     GetDigitsInVariant(Null) => Null
  '     GetDigitsInVariant("") => ""
  '     GetDigitsInVariant(2021-/05-May/-18, Tue) => 20210518
  '     GetDigitsInVariant(2021-05-18) => 20210518
  ' Notes:
  '     If the inputVariant is null, null will be returned.
  '     If the inputVariant is "", "" will be returned.
  ' Usage:
  '     VBA IDE Menu > Tools > References ...
  '       > "Microsoft VBScript Regular Expressions 5.5" > [OK]

  ' With an explicit object reference to RegExp we can get intellisense
  ' and review the object heirarchy with the object browser
  ' (VBA IDE Menu > View > Object Browser).
  Dim regex As VBScript_RegExp_55.RegExp
  Set regex = New VBScript_RegExp_55.RegExp
  
  Dim result As Variant
  result = Null
  
  If IsNull(inputVariant) Then
    result = Null
    
  Else
    With regex
      .Global = True
      .Pattern = "[^\d]+"
      result = .Replace(inputVariant, vbNullString)
    End With
  End If
  
  GetDigitsInVariant = result
End Function

Testing:

Private Sub TestGetDigitsInVariant()
  Dim dateVariants As Variant
  dateVariants = Array(Null, "", "2021-/05-May/-18, Tue", _
          "2021-05-18", "18/05/2021", "3434 ..,sdf,sfd 444")
  
  Dim dateVariant As Variant
  For Each dateVariant In dateVariants
    Debug.Print dateVariant & ": ", , GetDigitsInVariant(dateVariant)
  Next dateVariant
  Debug.Print
End Sub

This should do it:

function collect() {_x000D_
  var ret = {};_x000D_
  var len = arguments.length;_x000D_
  for (var i = 0; i < len; i++) {_x000D_
    for (p in arguments[i]) {_x000D_
      if (arguments[i].hasOwnProperty(p)) {_x000D_
        ret[p] = arguments[i][p];_x000D_
      }_x000D_
    }_x000D_
  }_x000D_
  return ret;_x000D_
}_x000D_
_x000D_
let a = { "one" : 1, "two" : 2 };_x000D_
let b = { "three" : 3 };_x000D_
let c = { "four" : 4, "five" : 5 };_x000D_
_x000D_
let d = collect(a, b, c);_x000D_
console.log(d);

Output:

{
  "one": 1,
  "two": 2,
  "three": 3,
  "four": 4,
  "five": 5
}

To net everything out, this is an example of temporarily disabling a warning:

#pragma GCC diagnostic push
#pragma GCC diagnostic ignored "-Wunused-result"
    write(foo, bar, baz);
#pragma GCC diagnostic pop

You can check the GCC documentation on diagnostic pragmas for more details.

Android WebView fix ERR_CACHE_MISS error solution

you just need add one line code <uses-permission android:name="android.permission.INTERNET"/> in your app/src/main/AndroidManifest.xml file as below screenshots shows.

1. before

2. after

Create a URI like this one:

https://maps.google.com/?q=[lat],[long]

For example:

https://maps.google.com/?q=-37.866963,144.980615

or, if you are using the javascript API

map.setCenter(new GLatLng(0,0))

This, and other helpful info comes from here:

https://developers.google.com/maps/documentation/javascript/reference/?csw=1#Map

Using sessionStorage for this is not possible.

From the MDN Docs

Opening a page in a new tab or window will cause a new session to be initiated.

That means that you can't share between tabs, for this you should use localStorage

The documentation on counting says that for group_by queries it is better to use func.count():

from sqlalchemy import func
session.query(Table.column, func.count(Table.column)).group_by(Table.column).all()

It's pretty simple really:

a[start:stop]  # items start through stop-1
a[start:]      # items start through the rest of the array
a[:stop]       # items from the beginning through stop-1
a[:]           # a copy of the whole array

There is also the step value, which can be used with any of the above:

a[start:stop:step] # start through not past stop, by step

The key point to remember is that the :stop value represents the first value that is not in the selected slice. So, the difference between stop and start is the number of elements selected (if step is 1, the default).

The other feature is that start or stop may be a negative number, which means it counts from the end of the array instead of the beginning. So:

a[-1]    # last item in the array
a[-2:]   # last two items in the array
a[:-2]   # everything except the last two items

Similarly, step may be a negative number:

a[::-1]    # all items in the array, reversed
a[1::-1]   # the first two items, reversed
a[:-3:-1]  # the last two items, reversed
a[-3::-1]  # everything except the last two items, reversed

Python is kind to the programmer if there are fewer items than you ask for. For example, if you ask for a[:-2] and a only contains one element, you get an empty list instead of an error. Sometimes you would prefer the error, so you have to be aware that this may happen.

Relation to slice() object

The slicing operator [] is actually being used in the above code with a slice() object using the : notation (which is only valid within []), i.e.:

a[start:stop:step]

is equivalent to:

a[slice(start, stop, step)]

Slice objects also behave slightly differently depending on the number of arguments, similarly to range(), i.e. both slice(stop) and slice(start, stop[, step]) are supported. To skip specifying a given argument, one might use None, so that e.g. a[start:] is equivalent to a[slice(start, None)] or a[::-1] is equivalent to a[slice(None, None, -1)].

While the :-based notation is very helpful for simple slicing, the explicit use of slice() objects simplifies the programmatic generation of slicing.

If you do not have file access to the repository, I prefer rsvndump (remote Subversion repository dump) to make the dump file.

Most of the roles you see were defined as part of ARIA 1.0, and then later incorporated into HTML via supporting specs like HTML-AAM. Some of the new HTML5 elements (dialog, main, etc.) are even based on the original ARIA roles.

http://www.w3.org/TR/wai-aria/

There are a few primary reasons to use roles in addition to your native semantic element.

Reason #1. Overriding the role where no host language element is appropriate or, for various reasons, a less semantically appropriate element was used.

In this example, a link was used, even though the resulting functionality is more button-like than a navigation link.

<a href="#" role="button" aria-label="Delete item 1">Delete</a>
<!-- Note: href="#" is just a shorthand here, not a recommended technique. Use progressive enhancement when possible. -->

Screen readers users will hear this as a button (as opposed to a link), and you can use a CSS attribute selector to avoid class-itis and div-itis.

[role="button"] {
  /* style these as buttons w/o relying on a .button class */
}

[Update 7 years later: removed the * selector to make some commenters happy, since the old browser quirk that required universal selector on attribute selectors is unnecessary in 2020.]

Reason #2. Backing up a native element's role, to support browsers that implemented the ARIA role but haven't yet implemented the native element's role.

For example, the "main" role has been supported in browsers for many years, but it's a relatively recent addition to HTML5, so many browsers don't yet support the semantic for <main>.

<main role="main">…</main>

This is technically redundant, but helps some users and doesn't harm any. In a few years, this technique will likely become unnecessary for main.

Reason #3. Update 7 years later (2020): As at least one commenter pointed out, this is now very useful for custom elements, and some spec work is underway to define the default accessibility role of a web component. Even if/once that API is standardized, there may be need to override the default role of a component.

Note/Reply

You also wrote:

I see some people make up their own. Is that allowed or a correct use of the role attribute?

That's an allowed use of the attribute unless a real role is not included. Browsers will apply the first recognized role in the token list.

<span role="foo link note bar">...</a>

Out of the list, only link and note are valid roles, and so the link role will be applied in the platform accessibility API because it comes first. If you use custom roles, make sure they don't conflict with any defined role in ARIA or the host language you're using (HTML, SVG, MathML, etc.)

This is what LINQ needs

public static IEnumerable<T> Except<T, TKey>(this IEnumerable<T> items, IEnumerable<T> other, Func<T, TKey> getKey) 
{
    return from item in items
            join otherItem in other on getKey(item)
            equals getKey(otherItem) into tempItems
            from temp in tempItems.DefaultIfEmpty()
            where ReferenceEquals(null, temp) || temp.Equals(default(T))
            select item; 
}

A StreamReader is for text, not plain bytes. Don't use a StreamReader, and instead read directly from the underlying stream.

I am using Bootstrap v3.3.4 and using the code:

 $('.datepicker').datepicker({
    dateFormat: 'dd-mm-yy'
 });

Output is: 16-07-2015

Note: only need "yy" for full year.

Real problem is when you need draw some tile/sprites intersecting/spanning two or more other tiles.

After 2 (hard) months of personal analisys of problem I finally found and implemented a "correct render drawing" for my new cocos2d-js game. Solution consists in mapping, for each tile (susceptible), which sprites are "front, back, top and behind". Once doing that you can draw them following a "recursive logic".

Use

sudo pip install virtualenv

Apparently you will have powers of administrator when adding "sudo" before the line... just don't forget your password.

$('.checkbox').click(function(){
  if ($('.checkbox:checked').length >= 3) {
    $(".checkbox").not(":checked").attr("disabled",true);
  }
  else 
    $(".checkbox").not(":checked").removeAttr('disabled');
});

i used this.

I thought I'd try code this up for fun:

graph = {
        '1': ['2', '3', '4'],
        '2': ['5', '6'],
        '5': ['9', '10'],
        '4': ['7', '8'],
        '7': ['11', '12']
        }

def bfs(graph, forefront, end):
    # assumes no cycles

    next_forefront = [(node, path + ',' + node) for i, path in forefront if i in graph for node in graph[i]]

    for node,path in next_forefront:
        if node==end:
            return path
    else:
        return bfs(graph,next_forefront,end)

print bfs(graph,[('1','1')],'11')

# >>>
# 1, 4, 7, 11

If you want cycles you could add this:

for i, j in for_front: # allow cycles, add this code
    if i in graph:
        del graph[i]

Try Plugins -> XML Tools -> Pretty Print (libXML) or (XML only - with line breaks Ctrl + Alt + Shift + B)

You may need to install XML Tools using your plugin manager in order to get this option in your menu.

In my experience, libXML gives nice output but only if the file is 100% correctly formed.

 @Override
 public boolean onOptionsItemSelected(MenuItem item) {
      int id = item.getItemId();

      if ( id == android.R.id.home ) {
          finish();
          return true;
      }

      return super.onOptionsItemSelected(item);
 }

Try this it works both on toolbar back button as hardware back button.

First of all, with regards to FormatType.JSON: JSON is not a member of FormatType, it's a possible value of the type. FormatType isn't even a composite type — it's a scalar.

Second, the only way to do this is to create a mapping table. The more common way to do this in Objective-C is to create a series of constants referring to your "symbols", so you'd have NSString *FormatTypeJSON = @"JSON" and so on.

I need to integrate with a class that need a Stream to Write on it:

XmlSchema schema;
// ... Use "schema" ...

var ret = "";

using (var ms = new MemoryStream())
{
    schema.Write(ms);
    ret = Encoding.ASCII.GetString(ms.ToArray());
}
//here you can use "ret"
// 6 Lines of code

I create a simple class that can help to reduce lines of code for multiples use:

public static class MemoryStreamStringWrapper
{
    public static string Write(Action<MemoryStream> action)
    {
        var ret = "";
        using (var ms = new MemoryStream())
        {
            action(ms);
            ret = Encoding.ASCII.GetString(ms.ToArray());
        }

        return ret;
    }
}

then you can replace the sample with a single line of code

var ret = MemoryStreamStringWrapper.Write(schema.Write);

You can use triggers.

Also check this introduction guide to triggers.

using java you can do this:

Using the Scanner:

Scanner reader = new Scanner(System.in);
String line = reader.nextLine();
// now you can use some converter to change the String value to the value you need.
// for example Long.parseLong(line) or Integer.parseInt(line) or other type cast

Using the BufferedReader:

BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));
String line = reader.readLine();
// now you can use some converter to change the String value to the value you need.
// for example Long.parseLong(line) or Integer.parseInt(line) or other type cast

In the two cases you need to pass you Default input, in my case System.in

You can fire chnage event by these methods:

First

$('#selectid').change(function () {
    alert('This works');
}); 

Second

$(document).on('change', '#selectid', function() {
    alert('This Works');
});

Third

$(document.body).on('change','#selectid',function(){
    alert('This Works');
});

If this methods not working, check your jQuery working or not:

$(document).ready(function($) {
   alert('Jquery Working');
});

Not in MySQL. I tried it and I get the following error:

ERROR 1054 (42S22): Unknown column 'a' in 'field list'

I wrote this method:

    private string GetUrlParameter(HttpRequestBase request, string parName)
    {
        string result = string.Empty;

        var urlParameters = HttpUtility.ParseQueryString(request.Url.Query);
        if (urlParameters.AllKeys.Contains(parName))
        {
            result = urlParameters.Get(parName);
        }

        return result;
    }

And I call it like this:

string fooBar = GetUrlParameter(Request, "FooBar");
if (!string.IsNullOrEmpty(fooBar))
{

}

Use the parameter named as validate_certs to ignore the ssh validation

- ec2_ami:
    instance_id: i-0661fa8b45a7531a7
    wait: yes
    name: ansible
    validate_certs: false
    tags:
      Name: ansible
      Service: TestService

By doing this it ignores the ssh validation process

This snippet uses wmic.exe to build the date string. It isn't mangled by locale settings

                'data'=>'day', //set default value

numpy has a great tool for this task ("numpy.reshape") link to reshape documentation

a = [[ 0  1]
 [ 2  3]
 [ 4  5]
 [ 6  7]
 [ 8  9]
 [10 11]
 [12 13]
 [14 15]
 [16 17]]

`numpy.reshape(a,(3,3))`

you can also use the "-1" trick

`a = a.reshape(-1,3)`

the "-1" is a wild card that will let the numpy algorithm decide on the number to input when the second dimension is 3

so yes.. this would also work: a = a.reshape(3,-1)

and this: a = a.reshape(-1,2) would do nothing

and this: a = a.reshape(-1,9) would change the shape to (2,9)

You can try the display:inline-block and :after.Like this:

HTML

<ul>
    <li><a href="">I would like this text centered vertically</a></li>
</ul>

CSS

li a {
    width: 300px;
    height: 100px;
    margin: auto 0;
    display: inline-block;
    vertical-align: middle;
    background: red;  
}
li a:after {
  content:"";
  display: inline-block;
  width: 1px solid transparent;
  height: 100%;
  vertical-align: middle;
}

Please view the demo.

Use RegExp, In case if any other options do not work for you, RegExp is a good option. It makes the string case insensitive.

var username = new RegExp("^" + "John" + "$", "i");;

use username in queries, and then its done.

I hope it will work for you too. All the Best.

When you have changes on your working copy, from command line do:

git stash 

This will stash your changes and clear your status report

git pull

This will pull changes from upstream branch. Make sure it says fast-forward in the report. If it doesn't, you are probably doing an unintended merge

git stash pop

This will apply stashed changes back to working copy and remove the changes from stash unless you have conflicts. In the case of conflict, they will stay in stash so you can start over if needed.

if you need to see what is in your stash

git stash list

In my case, the problem was a folder in the project directory containing 300k+ files totaling 11Gb. This was just a temporary folder with images results of some computation. After moving this folder out of the project structure, the slowness disappeared. I hope this can help someone, please check your project structure to see if there is anything that is not necessary.

The full list is:

DB, DW, DD, DQ, DT, DDQ, and DO (used to declare initialized data in the output file.)

See: http://www.tortall.net/projects/yasm/manual/html/nasm-pseudop.html

They can be invoked in a wide range of ways: (Note: for Visual-Studio - use "h" instead of "0x" syntax - eg: not 0x55 but 55h instead):

    db      0x55                ; just the byte 0x55
    db      0x55,0x56,0x57      ; three bytes in succession
    db      'a',0x55            ; character constants are OK
    db      'hello',13,10,'$'   ; so are string constants
    dw      0x1234              ; 0x34 0x12
    dw      'A'                 ; 0x41 0x00 (it's just a number)
    dw      'AB'                ; 0x41 0x42 (character constant)
    dw      'ABC'               ; 0x41 0x42 0x43 0x00 (string)
    dd      0x12345678          ; 0x78 0x56 0x34 0x12
    dq      0x1122334455667788  ; 0x88 0x77 0x66 0x55 0x44 0x33 0x22 0x11
    ddq     0x112233445566778899aabbccddeeff00
    ; 0x00 0xff 0xee 0xdd 0xcc 0xbb 0xaa 0x99
    ; 0x88 0x77 0x66 0x55 0x44 0x33 0x22 0x11
    do      0x112233445566778899aabbccddeeff00 ; same as previous
    dd      1.234567e20         ; floating-point constant
    dq      1.234567e20         ; double-precision float
    dt      1.234567e20         ; extended-precision float

DT does not accept numeric constants as operands, and DDQ does not accept float constants as operands. Any size larger than DD does not accept strings as operands.

It seems you have found your solution, but still it will be helpful to others, on this page on point based on Chrome 59.

4.Note the red triangle in the top-right of the Animation Frame Fired event. Whenever you see a red triangle, it's a warning that there may be an issue related to this event.

If you hover on these triangle you can see those are the violation handler errors and as per point 4. yes there is some issue related to that event.

If you want to set cookie and get it outside of request, Laravel is not your friend.

Laravel cookies are part of Request, so if you want to do this outside of Request object, use good 'ole PHP setcookie(..) and $_COOKIE to get it.

You could easily do it with an IntStream and the max() method.

Example

public static int maxValue(final int[] intArray) {
  return IntStream.range(0, intArray.length).map(i -> intArray[i]).max().getAsInt();
}

Explanation

1. range(0, intArray.length) - To get a stream with as many elements as present in the intArray.

2. map(i -> intArray[i]) - Map every element of the stream to an actual element of the intArray.

3. max() - Get the maximum element of this stream as OptionalInt.

4. getAsInt() - Unwrap the OptionalInt. (You could also use here: orElse(0), just in case the OptionalInt is empty.)

You need to create a view model. Something like this should do...

public class FullNameViewModel
{
     public string FirstName { get; set; }
     public string LastName { get; set; }

     public FullNameViewModel() { } 

     public FullNameViewModel(string firstName, string lastName)
     {
          this.FirstName = firstName;
          this.LastName = lastName;
     }

}

then from your action result pass the model

return View("FullName", new FullNameViewModel("John", "Doe"));

and you will be able to access @Model.FirstName and @Model.LastName accordingly.

Hope this helps somebody: I've been using the registry-based enumeration in my scripts (as suggested by some of the answers above), but have found that it does not properly enumerate 64-bit software when run on Windows 10 x64 via SCCM (which uses a 32-bit client). Found something like this to be the most straightforward solution in my particular case:

Function Get-Programs($Bits) {
  $Result = @()
  $Output = (reg query HKLM\Software\Microsoft\Windows\CurrentVersion\Uninstall /reg:$Bits /s)

  Foreach ($Line in $Output) {
    If ($Line -match '^\s+DisplayName\s+REG_SZ\s+(.+?)$') {
      $Result += New-Object PSObject -Property @{
        DisplayName = $matches[1];
        Bits = "$($Bits)-bit";
      }
    }
  }

  $Result
}

$Software  = Get-Programs 32
$Software += Get-Programs 64

Realize this is a little too Perl-ish in a bad way, but all other alternatives I've seen involved insanity with wrapper scripts and similar clever-clever solutions, and this seems a little more human.

P.S. Trying really hard to refrain from dumping a ton of salt on Microsoft here for making an absolutely trivial thing next to impossible. I.e., enumerating all MS Office versions in use on a network is a task to make a grown man weep.

Good question. These two operators work the same in PHP and C#.

| is a bitwise OR. It will compare two values by their bits. E.g. 1101 | 0010 = 1111. This is extremely useful when using bit options. E.g. Read = 01 (0X01) Write = 10 (0X02) Read-Write = 11 (0X03). One useful example would be opening files. A simple example would be:

File.Open(FileAccess.Read | FileAccess.Write);  //Gives read/write access to the file

|| is a logical OR. This is the way most people think of OR and compares two values based on their truth. E.g. I am going to the store or I will go to the mall. This is the one used most often in code. For example:

if(Name == "Admin" || Name == "Developer") { //allow access } //checks if name equals Admin OR Name equals Developer

I just made a class to handle this with Generics, so it can be used with all the object types that are serializable:

public class SerializableManager {

    /**
     * Saves a serializable object.
     *
     * @param context The application context.
     * @param objectToSave The object to save.
     * @param fileName The name of the file.
     * @param <T> The type of the object.
     */

    public static <T extends Serializable> void saveSerializable(Context context, T objectToSave, String fileName) {
        try {
            FileOutputStream fileOutputStream = context.openFileOutput(fileName, Context.MODE_PRIVATE);
            ObjectOutputStream objectOutputStream = new ObjectOutputStream(fileOutputStream);

            objectOutputStream.writeObject(objectToSave);

            objectOutputStream.close();
            fileOutputStream.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

    /**
     * Loads a serializable object.
     *
     * @param context The application context.
     * @param fileName The filename.
     * @param <T> The object type.
     *
     * @return the serializable object.
     */

    public static<T extends Serializable> T readSerializable(Context context, String fileName) {
        T objectToReturn = null;

        try {
            FileInputStream fileInputStream = context.openFileInput(fileName);
            ObjectInputStream objectInputStream = new ObjectInputStream(fileInputStream);
            objectToReturn = (T) objectInputStream.readObject();

            objectInputStream.close();
            fileInputStream.close();
        } catch (IOException | ClassNotFoundException e) {
            e.printStackTrace();
        }

        return objectToReturn;
    }

    /**
     * Removes a specified file.
     *
     * @param context The application context.
     * @param filename The name of the file.
     */

    public static void removeSerializable(Context context, String filename) {
        context.deleteFile(filename);
    }

}

This is how you would drop the constraint

ALTER TABLE <schema_name, sysname, dbo>.<table_name, sysname, table_name>
   DROP CONSTRAINT <default_constraint_name, sysname, default_constraint_name>
GO

With a script

-- t-sql scriptlet to drop all constraints on a table
DECLARE @database nvarchar(50)
DECLARE @table nvarchar(50)

set @database = 'dotnetnuke'
set @table = 'tabs'

DECLARE @sql nvarchar(255)
WHILE EXISTS(select * from INFORMATION_SCHEMA.TABLE_CONSTRAINTS where constraint_catalog = @database and table_name = @table)
BEGIN
    select    @sql = 'ALTER TABLE ' + @table + ' DROP CONSTRAINT ' + CONSTRAINT_NAME 
    from    INFORMATION_SCHEMA.TABLE_CONSTRAINTS 
    where    constraint_catalog = @database and 
            table_name = @table
    exec    sp_executesql @sql
END

To format code in-line within your text, use the '`' character to surround your code. Usually located to the left of the '1' key on your keyboard.

Example:

`printf("Hello World");`

Same delimiter as Stack Exchange!

You can use this function to get the absolute value:

+(NSNumber *)absoluteValue:(NSNumber *)input {
  return [NSNumber numberWithDouble:fabs([input doubleValue])];
}

this should help you maybe...

If your filenames contain no whitepace and you don't have any subdirectories, you can use a simple for loop:

$ for FILENAME in *; do mv $FILENAME Unix_$FILENAME; done 

Otherwise use the convenient rename command (which is a perl script) - although it might not be available out of the box on every Unix (e.g. OS X doesn't come with rename).

A short overview at debian-administration.org:

• Easily renaming multiple files

If your filenames contain whitespace it's easier to use find, on Linux the following should work:

$ find . -type f -name '*' -printf "echo mv '%h/%f' '%h/Unix_%f\n'" | sh

On BSD systems, there is no -printf option, unfortunately. But GNU findutils should be installable (on e.g. Mac OS X with brew install findutils).

$ gfind . -type f -name '*' -printf "mv \"%h/%f\" \"%h/Unix_%f\"\n" | sh

Here is example which can give you some hints to iterate through existing array and add items to new array. I use UnderscoreJS Module to use as my utility file.

You can download from (https://npmjs.org/package/underscore)

$ npm install underscore

Here is small snippet to demonstrate how you can do it.

var _ = require("underscore");
var calendars = [1, "String", {}, 1.1, true],
    newArray = [];

_.each(calendars, function (item, index) {
    newArray.push(item);
});

console.log(newArray);

This question is old and although you managed to make it work but I feel it would be helpful if I make clear some of points you have raised here.

First about directory name having spaces. I have been playing with apache2 configuration files and I have discovered that, if the directory name has space then enclose it in double quotes and all problems disappear. For example...

    NameVirtualHost     local.webapp.org
    <VirtualHost local.webapp.org:80>
        ServerAdmin [email protected]
        DocumentRoot "E:/Project/my php webapp"
        ServerName local.webapp.org
    </VirtualHost>

Note the way DocumentRoot line is written.

Second is about Access forbidden from xampp. I found that default xampp configuration (..path to xampp/apache/httpd.conf) has a section that looks like the following.

    <Directory>
        AllowOverride none
        Require all denied
    </Directory>

Change it and make it look like below. Save the file restart apache from xampp and that solves the problem.

    <Directory>
       Options Indexes FollowSymLinks Includes ExecCGI
       AllowOverride none
       Require all granted
    </Directory>

I had a similar problem with Ant build (started by hand from IDEA GUI). In my case there was the right solution to right click on the Ant task, choose properties and set a higher value to "Maximum heap space (Mb):" and "Maximum stack space (Mb):" input fields.

In JavaScript, you call the replace method on the String object, e.g. "this is some sample text that i want to replace".replace("want", "dont want"), which will return the replaced string.

var text = "this is some sample text that i want to replace";
var new_text = text.replace("want", "dont want"); // new_text now stores the replaced string, leaving the original untouched

I had "C:\Users\User Name\OneDrive\Fonts", which was mklink'ed ( /D ) to "C:\Windows\Fonts", and I got the same problem. In my case

cd "C:\Users\User Name\OneDrive"

rd /s Fonts

Y (to confirm the action)

helped me. I hope, that it helps you too ;D

Unless you do some kind of post-processing work, the video will never be better than the original frames. Also just like a flip-book, if you have a big "jump" between keyframes it will look funny. You generally need enough "tweens" in between the keyframes to give smooth animation. HTH
