A "BEFORE-INSERT"-trigger is the only way to realize same-table updates on an insert, and is only possible from MySQL 5.5+. However, the value of an auto-increment field is only available to an "AFTER-INSERT" trigger - it defaults to 0 in the BEFORE-case. Therefore the following example code which would set a previously-calculated surrogate key value based on the auto-increment value id will compile, but not actually work since NEW.id will always be 0:

create table products(id int not null auto_increment, surrogatekey varchar(10), description text);
create trigger trgProductSurrogatekey before insert on product
for each row set NEW.surrogatekey = 
  (select surrogatekey from surrogatekeys where id = NEW.id);

Although @Remus Rusanu's is already an excelent answer, in case one is looking forward a better insight on SQL Server's Deadlock causes and trace strategies, I would suggest you to read Brad McGehee's How to Track Down Deadlocks Using SQL Server 2005 Profiler

If you don't have a version of date that supports --yesterday and you don't want to use perl, you can use this handy ksh script of mine. By default, it returns yesterday's date, but you can feed it a number and it tells you the date that many days in the past. It starts to slow down a bit if you're looking far in the past. 100,000 days ago it was 1/30/1738, though my system took 28 seconds to figure that out.

    #! /bin/ksh -p

    t=`date +%j`
    ago=$1
    ago=${ago:=1} # in days
    y=`date +%Y`

    function build_year {
            set -A j X $( for m in 01 02 03 04 05 06 07 08 09 10 11 12
                    {
                            cal $m $y | sed -e '1,2d' -e 's/^/ /' -e "s/ \([0-9]\)/ $m\/\1/g"
                    } )
            yeardays=$(( ${#j[*]} - 1 ))
    }

    build_year

    until [ $ago -lt $t ]
    do
            (( y=y-1 ))
            build_year
            (( ago = ago - t ))
            t=$yeardays
    done

    print ${j[$(( t - ago ))]}/$y

I read the comments about contacts app and how it use a theme for each contact.

Probably, contacts app has some predefine themes (for each material primary color from here: http://www.google.com/design/spec/style/color.html).

You can apply a theme before a the setContentView method inside onCreate method.

Then the contacts app can apply a theme randomly to each user.

This method is:

setTheme(R.style.MyRandomTheme);

But this method has a problem, for example it can change the toolbar color, the scroll effect color, the ripple color, etc, but it cant change the status bar color and the navigation bar color (if you want to change it too).

Then for solve this problem, you can use the method before and:

if (Build.VERSION.SDK_INT >= 21) {
        getWindow().setNavigationBarColor(getResources().getColor(R.color.md_red_500));
        getWindow().setStatusBarColor(getResources().getColor(R.color.md_red_700));
    }

This two method change the navigation and status bar color. Remember, if you set your navigation bar translucent, you can't change its color.

This should be the final code:

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setTheme(R.style.MyRandomTheme);
    if (Build.VERSION.SDK_INT >= 21) {
        getWindow().setNavigationBarColor(getResources().getColor(R.color.myrandomcolor1));
        getWindow().setStatusBarColor(getResources().getColor(R.color.myrandomcolor2));
    }
    setContentView(R.layout.activity_main);

}

You can use a switch and generate random number to use random themes, or, like in contacts app, each contact probably has a predefine number associated.

A sample of theme:

<style name="MyRandomTheme" parent="Theme.AppCompat.NoActionBar">
    <!-- Customize your theme here. -->
    <item name="colorPrimary">@color/myrandomcolor1</item>
    <item name="colorPrimaryDark">@color/myrandomcolor2</item>
    <item name="android:navigationBarColor">@color/myrandomcolor1</item>
</style>

Sorry for my english.

The configuration I use in my parent level pom where I have separate unit and integration test phases.

I configure the following properties in the parent POM Properties

    <maven.surefire.report.plugin>2.19.1</maven.surefire.report.plugin>
    <jacoco.plugin.version>0.7.6.201602180812</jacoco.plugin.version>

    <skip.surefire.tests>${skipTests}</skip.surefire.tests>
    <skip.failsafe.tests>${skipTests}</skip.failsafe.tests>

I place the plugin definitions under plugin management.

Note that I define a property for surefire (surefireArgLine) and failsafe (failsafeArgLine) arguments to allow jacoco to configure the javaagent to run with each test.

I had similar problem at my work.

Building the parent project without dependency created parent_project.pom file in the .m2 folder.

Then add the child module in the parent POM and run Maven build.

<modules>
    <module>module1</module>
    <module>module2</module>
    <module>module3</module>
    <module>module4</module>
</modules>

Here's a simpler solution:

var uri = new Uri("http://www.example.com/mypage.aspx?myvalue1=hello&myvalue2=goodbye");
string path = uri.GetLeftPart(UriPartial.Path);

Extends Selenium WebDriver classes to include the request function from the Requests library, while doing all the needed cookie and request headers handling.

Example:

from seleniumrequests import Firefox

webdriver = Firefox()
response = webdriver.request('POST', 'url here', data={"param1": "value1"})
print(response)

C++, O(n):

long long prod = accumulate(in.begin(), in.end(), 1LL, multiplies<int>());
transform(in.begin(), in.end(), back_inserter(res),
          bind1st(divides<long long>(), prod));

To make the answer provided by @abourget more complete, the value of scopeValue[field] in the following line of code could be undefined. This would result in an error when setting subfield:

<textarea ng-model="scopeValue[field][subfield]"></textarea>

One way of solving this problem is by adding an attribute ng-focus="nullSafe(field)", so your code would look like the below:

<textarea ng-focus="nullSafe(field)" ng-model="scopeValue[field][subfield]"></textarea>

Then you define nullSafe( field ) in a controller like the below:

$scope.nullSafe = function ( field ) {
  if ( !$scope.scopeValue[field] ) {
    $scope.scopeValue[field] = {};
  }
};

This would guarantee that scopeValue[field] is not undefined before setting any value to scopeValue[field][subfield].

Note: You can't use ng-change="nullSafe(field)" to achieve the same result because ng-change happens after the ng-model has been changed, which would throw an error if scopeValue[field] is undefined.

We use recaptcha-V3 only to see site traffic quality, and used it as non blocking. Since recaptcha-V3 doesn't require to show on site and can be used as hidden but you have to show recaptcha privacy etc links (as recommended)

Script Tag in Head

<script src="https://www.google.com/recaptcha/api.js?onload=ReCaptchaCallbackV3&render='SITE KEY' async defer></script>

Note: "async defer" make sure its non blocking which is our specific requirement

JS Code:

<script>
    ReCaptchaCallbackV3 = function() {
        grecaptcha.ready(function() {
            grecaptcha.execute("SITE KEY").then(function(token) {
                $.ajax({
                    type: "POST",
                    url: `https://api.${window.appInfo.siteDomain}/v1/recaptcha/score`,
                    data: {
                        "token" : token,
                    },
                    success: function(data) {
                        if(data.response.success) {
                            window.recaptchaScore = data.response.score;
                            console.log('user score ' + data.response.score)
                        }
                    },
                    error: function() {
                        console.log('error while getting google recaptcha score!')
                    }
                });

            });
        });
    };
</script> 

HTML/Css Code:

there is no html code since our requirement is just to get score and don't want to show recaptcha badge.

Backend - Laravel Code:

Route:

Route::post('/recaptcha/score', 'Api\\ReCaptcha\\RecaptchaScore@index');


Class:

class RecaptchaScore extends Controller
{
    public function index(Request $request)
    {
        $score = null;

        $response = (new Client())->request('post', 'https://www.google.com/recaptcha/api/siteverify', [
            'form_params' => [
                'response' => $request->get('token'),
                'secret' => 'SECRET HERE',
            ],
        ]);

        $score = json_decode($response->getBody()->getContents(), true);

        if (!$score['success']) {
            Log::warning('Google ReCaptcha Score', [
                'class' => __CLASS__,
                'message' => json_encode($score['error-codes']),
            ]);
        }

        return [
            'response' => $score,
        ];
    }
} 

we get back score and save in variable which we later user when submit form.

Generic functional form

def select_columns(data_frame, column_names):
    new_frame = data_frame.loc[:, column_names]
    return new_frame

Specific for your problem above

selected_columns = ['A', 'C', 'D']
new = select_columns(old, selected_columns)

It looks like, cargo can have one or more item. Each item would have a reference to its corresponding cargo.

From the log, item object is inserted first and then an attempt is made to update the cargo object (which does not exist).

I guess what you actually want is cargo object to be created first and then the item object to be created with the id of the cargo object as the reference - so, essentally re-look at the save() method in the Action class.

You have to use a Class instance because of the generic type erasure during compilation.

public static <T> T convertInstanceOfObject(Object o, Class<T> clazz) {
    try {
        return clazz.cast(o);
    } catch(ClassCastException e) {
        return null;
    }
}

The declaration of that method is:

public T cast(Object o)

This can also be used for array types. It would look like this:

final Class<int[]> intArrayType = int[].class;
final Object someObject = new int[]{1,2,3};
final int[] instance = convertInstanceOfObject(someObject, intArrayType);

Note that when someObject is passed to convertToInstanceOfObject it has the compile time type Object.

Eric Niebler is working on a range-proposal and some of the examples show how to remove certain elements. Removing 8. Does create a new vector.

#include <iostream>
#include <range/v3/all.hpp>

int main(int argc, char const *argv[])
{
    std::vector<int> vi{2,4,6,8,10};
    for (auto& i : vi) {
        std::cout << i << std::endl;
    }
    std::cout << "-----" << std::endl;
    std::vector<int> vim = vi | ranges::view::remove_if([](int i){return i == 8;});
    for (auto& i : vim) {
        std::cout << i << std::endl;
    }
    return 0;
}

outputs

2
4
6
8
10

In my case, I forgot to tell the type controller that the response is a JSON object. response.setContentType("application/json");

add automaticallyImplyLeading: false, into your Scaffold's Appbar

The best way to solve this problem would be by starting with customizing Bootstrap using their customization tools.

http://getbootstrap.com/customize/

Go down to @headings-color and change it from "inherit" to something that you would like your headers to be across the site (if you like the default just change it to #333).

Note that this will keep all your headings the same color, as you requested.

Now in order to accomplish what you want that after you make this change you can now overwrite them specifically in your own CSS to apply your own color to them. The "inherit" keyword I always have found to be a pain in frameworks.

Complementing in C# with SQL:

SqlConnection conn = new SqlConnection("ConnectionString");
conn.Open();
SqlCommand comm = new SqlCommand("SELECT COUNT(*) FROM table_name", conn);
Int32 count = Convert.ToInt32(comm.ExecuteScalar());
if (count > 0)
{
    lblCount.Text = Convert.ToString(count.ToString()); //For example a Label
}
else
{
    lblCount.Text = "0";
}
conn.Close(); //Remember close the connection

RUN and ENTRYPOINT are two different ways to execute a script.

RUN means it creates an intermediate container, runs the script and freeze the new state of that container in a new intermediate image. The script won't be run after that: your final image is supposed to reflect the result of that script.

ENTRYPOINT means your image (which has not executed the script yet) will create a container, and runs that script.

In both cases, the script needs to be added, and a RUN chmod +x /bootstrap.sh is a good idea.

It should also start with a shebang (like #!/bin/sh)

Considering your script (bootstrap.sh: a couple of git config --global commands), it would be best to RUN that script once in your Dockerfile, but making sure to use the right user (the global git config file is %HOME%/.gitconfig, which by default is the /root one)

Add to your Dockerfile:

RUN /bootstrap.sh

Then, when running a container, check the content of /root/.gitconfig to confirm the script was run.

jQuery Validation Unobtrusive Native is a collection of ASP.Net MVC HTML helper extensions. These make use of jQuery Validation's native support for validation driven by HTML 5 data attributes. Microsoft shipped jquery.validate.unobtrusive.js back with MVC 3. It provided a way to apply data model validations to the client side using a combination of jQuery Validation and HTML 5 data attributes (that's the "unobtrusive" part).

If your activity extends AppCompatActivity you need to override the onSupportNavigateUp() method like so:

public class SecondActivity extends AppCompatActivity {

   @Override
   protected void onCreate(Bundle savedInstanceState) {
       super.onCreate(savedInstanceState);
       setContentView(R.layout.activity_second);
       Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
       setSupportActionBar(toolbar);
       getSupportActionBar().setHomeButtonEnabled(true);
       getSupportActionBar().setDisplayHomeAsUpEnabled(true);
       ...
   }

   @Override
   public void onBackPressed() {
       super.onBackPressed();
       this.finish();
   }

   @Override
   public boolean onSupportNavigateUp() {
       onBackPressed();
       return true;
   }
}

Handle your logic in your onBackPressed() method and just call that method in onSupportNavigateUp() so the back button on the phone and the arrow on the toolbar do the same thing.

I know this is long stagnant topic, but in case anyone searches here is how I deal with multi table foreign keys. With this technique you do not have any DBA enforced cascade operations, so please make sure you deal with DELETE and such in your code.

Table 2 Meat
Pk_meatid, name

1, fruit
2, meat
3, desert

Table 4 Basket (Table using fk_s)

Considering all of your API requests located with a url pattern of /api/.. you can tell spring to secure only this url pattern by using below configuration. Which means that you are telling spring what to secure instead of what to ignore.

@Override
protected void configure(HttpSecurity http) throws Exception {
  http
    .csrf().disable()
     .authorizeRequests()
      .antMatchers("/api/**").authenticated()
      .anyRequest().permitAll()
      .and()
    .httpBasic().and()
    .sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS);
}

I would disagree with converting it on the server side. If you do that it's going to come back as a string type rather than a date type with all that entails (it will sort as a string for example)

My principle when dealing with dates is to keep them typed as a date for as long as you possibly can.

If your facing a performance bottleneck on the report server there are better ways to handle it than compromising your logic.

>>> range(6, 0, -1)
[6, 5, 4, 3, 2, 1]

I hope this helps someone else since a,b,x,y don't have much meaning to me! Suppose you have a text full of sentences and you want an array of words.

# Without list comprehension
list_of_words = []
for sentence in text:
    for word in sentence:
       list_of_words.append(word)
return list_of_words

I like to think of list comprehension as stretching code horizontally.

Try breaking it up into:

# List Comprehension 
[word for sentence in text for word in sentence]

Example:

>>> text = (("Hi", "Steve!"), ("What's", "up?"))
>>> [word for sentence in text for word in sentence]
['Hi', 'Steve!', "What's", 'up?']

This also works for generators

>>> text = (("Hi", "Steve!"), ("What's", "up?"))
>>> gen = (word for sentence in text for word in sentence)
>>> for word in gen: print(word)
Hi
Steve!
What's
up?

// you need to have a list of data that you want the spinner to display
List<String> spinnerArray =  new ArrayList<String>();
spinnerArray.add("item1");
spinnerArray.add("item2");

ArrayAdapter<String> adapter = new ArrayAdapter<String>(
    this, android.R.layout.simple_spinner_item, spinnerArray);

adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
Spinner sItems = (Spinner) findViewById(R.id.spinner1);
sItems.setAdapter(adapter);

also to find out what is selected you could do something like this

String selected = sItems.getSelectedItem().toString();
if (selected.equals("what ever the option was")) {
}

genrsa has been replaced by genpkey & when run manually in a terminal it will prompt for a password:

openssl genpkey -aes-256-cbc -algorithm RSA -out /etc/ssl/private/key.pem -pkeyopt rsa_keygen_bits:4096

However when run from a script the command will not ask for a password so to avoid the password being viewable as a process use a function in a shell script:

get_passwd() {
    local passwd=
    echo -ne "Enter passwd for private key: ? "; read -s passwd
    openssl genpkey -aes-256-cbc -pass pass:$passwd -algorithm RSA -out $PRIV_KEY -pkeyopt rsa_keygen_bits:$PRIV_KEYSIZE
}

What you're trying to accomplish is called Reverse DNS lookup.

However, for the timeout part I have read about people running into problems with this. I would check out PyDNS or this solution for more advanced treatment.

Date has the time part, so we only need to extract it from Date

I personally prefer the default format parameter of the Date when date and time needs to be separated instead of using the extra SimpleDateFormat

Date date = new Date()
String datePart = date.format("dd/MM/yyyy")
String timePart = date.format("HH:mm:ss")

println "datePart : " + datePart + "\ttimePart : " + timePart

:sav newfile | !rm #

Note that it does not remove the old file from the buffer list. If that's important to you, you can use the following instead:

HEAD actually is just a file for storing current branch info

and if you use HEAD in your git commands you are pointing to your current branch

you can see the data of this file by cat .git/HEAD

You can use this snippet :-D

using System;
using System.Reflection;

public static class EnumUtils
{
    public static T GetDefaultValue<T>()
        where T : struct, Enum
    {
        return (T)GetDefaultValue(typeof(T));
    }

    public static object GetDefaultValue(Type enumType)
    {
        var attribute = enumType.GetCustomAttribute<DefaultValueAttribute>(inherit: false);
        if (attribute != null)
            return attribute.Value;

        var innerType = enumType.GetEnumUnderlyingType();
        var zero = Activator.CreateInstance(innerType);
        if (enumType.IsEnumDefined(zero))
            return zero;

        var values = enumType.GetEnumValues();
        return values.GetValue(0);
    }
}

Example:

using System;

public enum Enum1
{
    Foo,
    Bar,
    Baz,
    Quux
}
public enum Enum2
{
    Foo  = 1,
    Bar  = 2,
    Baz  = 3,
    Quux = 0
}
public enum Enum3
{
    Foo  = 1,
    Bar  = 2,
    Baz  = 3,
    Quux = 4
}
[DefaultValue(Enum4.Bar)]
public enum Enum4
{
    Foo  = 1,
    Bar  = 2,
    Baz  = 3,
    Quux = 4
}

public static class Program 
{
    public static void Main() 
    {
        var defaultValue1 = EnumUtils.GetDefaultValue<Enum1>();
        Console.WriteLine(defaultValue1); // Foo

        var defaultValue2 = EnumUtils.GetDefaultValue<Enum2>();
        Console.WriteLine(defaultValue2); // Quux

        var defaultValue3 = EnumUtils.GetDefaultValue<Enum3>();
        Console.WriteLine(defaultValue3); // Foo

        var defaultValue4 = EnumUtils.GetDefaultValue<Enum4>();
        Console.WriteLine(defaultValue4); // Bar
    }
}

If url contains a certen string, redirect to index.php . You need to match against the %{REQUEST_URI} variable to check if the url contains a certen string.

To redirect example.com/foo/bar to /index.php if the uri contains bar anywhere in the uri string , you can use this :

RewriteEngine on

RewriteCond %{REQUEST_URI} bar
RewriteRule ^ /index.php [L,R]

This XPath is specific to the code snippet you've provided. To select <child> with id as #grand you can write //child[@id='#grand'].

To get age //child[@id='#grand']/@age

Hope this helps

Do git rebase -i <sha before the branches diverged> this will allow you to remove the merge commit and the log will be one single line as you wanted. You can also delete any commits that you do not want any more. The reason that your rebase wasn't working was that you weren't going back far enough.

WARNING: You are rewriting history doing this. Doing this with changes that have been pushed to a remote repo will cause issues. I recommend only doing this with commits that are local.

Create the file! try:

mkdir -p .android && touch ~/.android/repositories.cfg

Call the continuation with TaskScheduler.FromCurrentSynchronizationContext():

    Task UITask= task.ContinueWith(() =>
    {
     this.TextBlock1.Text = "Complete"; 
    }, TaskScheduler.FromCurrentSynchronizationContext());

This is suitable only if the current execution context is on the UI thread.

You can use map function

{Object.keys(tifs).map(key => (
    <option value={key}>{tifs[key]}</option>
))}

You can use MODIFY COLUMN to do this. Just do...

ALTER TABLE YourTable
MODIFY COLUMN your_column
your_previous_column_definition COMMENT "Your new comment"

substituting:

• YourTable with the name of your table
• your_column with the name of your comment
• your_previous_column_definition with the column's column_definition, which I recommend getting via a SHOW CREATE TABLE YourTable command and copying verbatim to avoid any traps.*
• Your new comment with the column comment you want.

For example...

mysql> CREATE TABLE `Example` (
    ->   `id` int(10) unsigned NOT NULL AUTO_INCREMENT,
    ->   `some_col` varchar(255) DEFAULT NULL,
    ->   PRIMARY KEY (`id`)
    -> );
Query OK, 0 rows affected (0.18 sec)

mysql> ALTER TABLE Example
    -> MODIFY COLUMN `id`
    -> int(10) unsigned NOT NULL AUTO_INCREMENT COMMENT 'Look, I''m a comment!';
Query OK, 0 rows affected (0.07 sec)
Records: 0  Duplicates: 0  Warnings: 0

mysql> SHOW CREATE TABLE Example;

* Whenever you use MODIFY or CHANGE clauses in an ALTER TABLE statement, I suggest you copy the column definition from the output of a SHOW CREATE TABLE statement. This protects you from accidentally losing an important part of your column definition by not realising that you need to include it in your MODIFY or CHANGE clause. For example, if you MODIFY an AUTO_INCREMENT column, you need to explicitly specify the AUTO_INCREMENT modifier again in the MODIFY clause, or the column will cease to be an AUTO_INCREMENT column. Similarly, if the column is defined as NOT NULL or has a DEFAULT value, these details need to be included when doing a MODIFY or CHANGE on the column or they will be lost.

I have crafted this piece of code that worked for me to detect when I scroll to the end of an element!

let element = $('.element');

if ($(document).scrollTop() > element.offset().top + element.height()) {

     /// do something ///
}

In angular 1.4 +, in addition to adding the dependency

angular.module('myApp', ['ngRoute'])

,we also need to reference the separate angular-route.js file

<script src="angular.js">
<script src="angular-route.js">

see https://docs.angularjs.org/api/ngRoute

Not quite, the AND has to be lower-case.

<xsl:when test="4 &lt; 5 and 1 &lt; 2">
<!-- do something -->
</xsl:when>

As stated by Harry Joy, you can do it on the onclick attr like so:

<input type="button" onclick="func1();func2();" value="Call2Functions" />

Or, in your JS like so:

document.getElementById( 'Call2Functions' ).onclick = function()
{
    func1();
    func2();
};

Or, if you are assigning an onclick programmatically, and aren't sure if a previous onclick existed (and don't want to overwrite it):

var Call2FunctionsEle = document.getElementById( 'Call2Functions' ),
    func1 = Call2FunctionsEle.onclick;

Call2FunctionsEle.onclick = function()
{
    if( typeof func1 === 'function' )
    {
        func1();
    }
    func2();
};

If you need the functions run in scope of the element which was clicked, a simple use of apply could be made:

document.getElementById( 'Call2Functions' ).onclick = function()
{
    func1.apply( this, arguments );
    func2.apply( this, arguments );
};

Chr(Number) should work for you.

select 'Hello' || chr(10) ||' world' from dual

Remember different platforms expect different new line characters:

• CHR(10) => LF, line feed (unix)
• CHR(13) => CR, carriage return (windows, together with LF)

This works: Change your file to:

LLKKKKKKKKMMMMMMMMNNNNNNNNNNNNN GGGGGGGGGHHHHHHHHHHHHHHHHHHHHEEEEEEEE

Then:

file = open("file.txt")
line = file.read()
words = line.split()

This creates a list named words that equals:

['LLKKKKKKKKMMMMMMMMNNNNNNNNNNNNN', 'GGGGGGGGGHHHHHHHHHHHHHHHHHHHHEEEEEEEE']

That got rid of the "\n". To answer the part about the brackets getting in your way, just do this:

for word in words: # Assuming words is the list above
    print word # Prints each word in file on a different line

Or:

print words[0] + ",", words[1] # Note that the "+" symbol indicates no spaces
#The comma not in parentheses indicates a space

This returns:

LLKKKKKKKKMMMMMMMMNNNNNNNNNNNNN, GGGGGGGGGHHHHHHHHHHHHHHHHHHHHEEEEEEEE

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

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

If you're using jQuery Cookie (https://plugins.jquery.com/cookie/), you can use decimal point or fractions.

As one day is 1, one minute would be 1 / 1440 (there's 1440 minutes in a day).

So 30 minutes is 30 / 1440 = 0.02083333.

Final code:

$.cookie("example", "foo", { expires: 30 / 1440, path: '/' });

I've added path: '/' so that you don't forget that the cookie is set on the current path. If you're on /my-directory/ the cookie is only set for this very directory.

In case you are using the annotation method for filter definition (as opposed to defining them in the web.xml), you can do so by just putting an array of mappings in the @WebFilter annotation:

/**
 * Filter implementation class LoginFilter
 */
@WebFilter(urlPatterns = { "/faces/Html/Employee","/faces/Html/Admin", "/faces/Html/Supervisor"})
public class LoginFilter implements Filter {
    ...

And just as an FYI, this same thing works for servlets using the servlet annotation too:

/**
 * Servlet implementation class LoginServlet
 */
@WebServlet({"/faces/Html/Employee", "/faces/Html/Admin", "/faces/Html/Supervisor"})
public class LoginServlet extends HttpServlet {
    ...

Do what is suggested in the answer, but make sure you also click inside the VM so that OSX has the focus before you plug in the phone. In my case, I had to do that to make it work.

According to Dangerously Set innerHTML,

Improper use of the innerHTML can open you up to a cross-site scripting (XSS) attack. Sanitizing user input for display is notoriously error-prone, and failure to properly sanitize is one of the leading causes of web vulnerabilities on the internet.

Our design philosophy is that it should be "easy" to make things safe, and developers should explicitly state their intent when performing “unsafe” operations. The prop name dangerouslySetInnerHTML is intentionally chosen to be frightening, and the prop value (an object instead of a string) can be used to indicate sanitized data.

After fully understanding the security ramifications and properly sanitizing the data, create a new object containing only the key __html and your sanitized data as the value. Here is an example using the JSX syntax:

function createMarkup() {
    return {
       __html: 'First · Second'    };
 }; 

<div dangerouslySetInnerHTML={createMarkup()} /> 

Read more about it using below link:

documentation: React DOM Elements - dangerouslySetInnerHTML.

The final column of my database (it's column F in the spreadsheet) is not used and therefore empty. When I imported the excel CSV file I got the "column count" error.

This is because excel was only saving the columns I use. A-E

Adding a 0 to the first row in F solved the problem, then I deleted it after upload was successful.

Hope this helps and saves someone else time and loss of hair :)

This worked for me:

       jQuery('#tblPaging').dataTable({
            "sort": true,
            "pageLength": 20
        });

How about this:

import sys
import subprocess

theproc = subprocess.Popen("myscript.py", shell = True)
theproc.communicate()                   # ^^^^^^^^^^^^

This tells subprocess to use the OS shell to open your script, and works on anything that you can just run in cmd.exe.

Additionally, this will search the PATH for "myscript.py" - which could be desirable.

In Chrome, go to options (Customize and Control, the 3 dots/bars at top right) ---> More Tools ---> save page as

save page as  
filename     : any_name.html 
save as type : webpage complete.

Then you will get any_name.html and any_name folder.

Here is another take with AWS Example of each service:

IaaS (Infrastructure as a Service): You get the whole infrastructure with hardware. You chose the type of OS that needs to be installed. You will have to install the necessary software.

AWS Example: EC2 which has only the hardware and you select the base OS to be installed. If you want to install Hadoop on that you have to do it yourself, it's just the base infrastructure AWS has provided.

PaaS (Platform as a Service): Provides you the infrastructure with OS and necessary base software. You will have to run your scripts to get the desired output.

AWS Example: EMR Which has the hardware (EC2) + Base OS + Hadoop software already installed. You will have to run hive/spark scripts to query tables and get results. You will need to invoke the instance and wait for 10 min for the setup to be ready. You have to take care of how many clusters you need based on the jobs you are running, but not worry about the cluster configuration.

SaaS (Software as a Service): You don't have to worry about Hardware or even Software. Everything will be installed and available for you to use instantly.

AWS Example: Athena, which is just a UI for you to query tables in S3 (with metadata stored in Glu). Just open the browser login to AWS and start running your queries, no worry about RAM/Storage/CPU/number of clusters, everything the cloud takes care of.

TLDR; Append Script path to the System Path by adding following in the entry point of your python script.

import os.path
import sys
PACKAGE_PARENT = '..'
SCRIPT_DIR = os.path.dirname(os.path.realpath(os.path.join(os.getcwd(), os.path.expanduser(__file__))))
sys.path.append(os.path.normpath(os.path.join(SCRIPT_DIR, PACKAGE_PARENT)))

Thats it now you can run your project in PyCharma as well as from Terminal!!

Using "groupby" and list comprehension:

Storing all the split dataframe in list variable and accessing each of the seprated dataframe by their index.

DF = pd.DataFrame({'chr':["chr3","chr3","chr7","chr6","chr1"],'pos':[10,20,30,40,50],})
ans = [pd.DataFrame(y) for x, y in DF.groupby('chr', as_index=False)]

accessing the separated DF like this:

ans[0]
ans[1]
ans[len(ans)-1] # this is the last separated DF

accessing the column value of the separated DF like this:

ansI_chr=ans[i].chr 

int b;
double a;
a=3669.0;
b=a;
printf("b=%d",b);

this code gives the output as b=3669 only you check it clearly.

Update: use Darin's / John Resig answer, just keep in mind that you dont need to specifiy thisArg for min, so Math.min.apply(null, arr) will work just fine.

or you can just sort the array and get value #1: [2,6,7,4,1].sort()[0]

[!] But without supplying custom number sorting function, this will only work in one, very limited case: positive numbers less than 10. See how it would break:

var a = ['', -0.1, -2, -Infinity, Infinity, 0, 0.01, 2, 2.0, 2.01, 11, 1, 1e-10, NaN];

// correct: 
a.sort( function (a,b) { return a === b ? 0 : a < b ? -1: 1} );
//Array [NaN, -Infinity, -2, -0.1, 0, "", 1e-10, 0.01, 1, 2, 2, 2.01, 11, Infinity]

// incorrect:
a.sort();
//Array ["", -0.1, -2, -Infinity, 0, 0.01, 1, 11, 1e-10, 2, 2, 2.01, Infinity, NaN]

And, also, array is changed in-place, which might not be what you want.

Regex to find trailing and leading whitespaces:

^[ \t]+|[ \t]+$

You just missed an extra pair of brackets for the "OR" symbol. The following should do the trick:

([0-9]+)\s+((\bseconds\b)|(\bminutes\b))

Without those you were either matching a number followed by seconds OR just the word minutes

Yet another way to do it:

//Where $file is an instance of Illuminate\Http\UploadFile
$extension = $file->getClientOriginalExtension();

Not a VIM user myself, so forgive me if this is totally offbase. But according to what I gather from the following VIM Tips site:

" where was an option set  
:scriptnames            : list all plugins, _vimrcs loaded (super)  
:verbose set history?   : reveals value of history and where set  
:function               : list functions  
:func SearchCompl       : List particular function

Use JContainer.Parse(str) method to check if the str is a valid Json. If this throws exception then it is not a valid Json.

JObject.Parse - Can be used to check if the string is a valid Json object
JArray.Parse - Can be used to check if the string is a valid Json Array
JContainer.Parse - Can be used to check for both Json object & Array

The Resource Kit has always included this. At least since Windows 2000.

Also, the Cygwin package has a sleep - plop that into your PATH and include the cygwin.dll (or whatever it's called) and way to go!

One last thing is to check for Event Listeners > "scroll" and test deleting them.

Even if you delete the Javascript that created them, the listeners will stick around and prevent scrolling.

Here is the Groovy way of accessing object properties:

this.class.simpleName    # returns the simple name of the current class

It is a very simple and effective utility build in jquery to implement pagination on html table http://tablesorter.com/docs/example-pager.html

Download the plugin from http://tablesorter.com/addons/pager/jquery.tablesorter.pager.js

After adding this plugin add following code in head script

$(document).ready(function() { 
    $("table") 
    .tablesorter({widthFixed: true, widgets: ['zebra']}) 
    .tablesorterPager({container: $("#pager")}); 
}); 

Other than using the Navigator/Proj Explorer and choosing files and doing 'Compare With'->'Each other'... I prefer opening both files in Eclipse and using 'Compare With'->'Opened Editor'->(pick the opened tab)... You can get this feature via the AnyEdit eclipse plugin located here (you can use Install Software via Eclipse->Help->Install New Software screen): http://andrei.gmxhome.de/eclipse/

I use this code piece while working with indexes for radio group:

radioGroup.check(radioGroup.getChildAt(index).getId());

Os X Mojave 10.14 has:

Error: The Command Line Tools header package must be installed on Mojave.

Solution. Go to

/Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg

location and install the package manually. And brew will start working and we can run:

brew uninstall --force git
brew cleanup --force -s git
brew prune
brew install git

Here's my solution

if [[ "${cms}" != +(wordpress|magento|typo3) ]]; then

Generate any number of hexadecimal character (e.g. 32):

(function(max){let r='';for(let i=0;i<max/13;i++)r+=(Math.random()+1).toString(16).substring(2);return r.substring(0,max).toUpperCase()})(32);

As already recommended, you can use tree. But for using it together with restructured text some additional parameters were required.

The standard tree output will not be printed if your're using pandoc to produce pdf.

tree --dirsfirst --charset=ascii /path/to/directory will produce a nice ASCII tree that can be integrated into your document like this:

Although this is a old post, I have spent 3 hours to fix my issue and I think this might help someone in future.

Here is my jquery-dialog hack to show html content inside an <iframe> :

let modalProperties = {autoOpen: true, width: 900, height: 600, modal: true, title: 'Modal Title'};
let modalHtmlContent = '<div>My Content First div</div><div>My Content Second div</div>';

// create wrapper iframe
let wrapperIframe = $('<iframe src="" frameborder="0" style="width:100%; height:100%;"></iframe>');

// create jquery dialog by a 'div' with 'iframe' appended
$("<div></div>").append(wrapperIframe).dialog(modalProperties);

// insert html content to iframe 'body'
let wrapperIframeDocument = wrapperIframe[0].contentDocument;
let wrapperIframeBody = $('body', wrapperIframeDocument);
wrapperIframeBody.html(modalHtmlContent);

jsfiddle demo

The method getContentAsByteArray() of the Spring class ContentCachingRequestWrapper reads the body multiple times, but the methods getInputStream() and getReader() of the same class do not read the body multiple times:

"This class caches the request body by consuming the InputStream. If we read the InputStream in one of the filters, then other subsequent filters in the filter chain can't read it anymore. Because of this limitation, this class is not suitable in all situations."

In my case more general solution that solved this problem was to add following three classes to my Spring boot project (and the required dependencies to the pom file):

CachedBodyHttpServletRequest.java:

public class CachedBodyHttpServletRequest extends HttpServletRequestWrapper {

    private byte[] cachedBody;

    public CachedBodyHttpServletRequest(HttpServletRequest request) throws IOException {
        super(request);
        InputStream requestInputStream = request.getInputStream();
        this.cachedBody = StreamUtils.copyToByteArray(requestInputStream);
    }

    @Override
    public ServletInputStream getInputStream() throws IOException {
        return new CachedBodyServletInputStream(this.cachedBody);
    }

    @Override
    public BufferedReader getReader() throws IOException {
        // Create a reader from cachedContent
        // and return it
        ByteArrayInputStream byteArrayInputStream = new ByteArrayInputStream(this.cachedBody);
        return new BufferedReader(new InputStreamReader(byteArrayInputStream));
    }
}

CachedBodyServletInputStream.java:

public class CachedBodyServletInputStream extends ServletInputStream {

    private InputStream cachedBodyInputStream;

    public CachedBodyServletInputStream(byte[] cachedBody) {
        this.cachedBodyInputStream = new ByteArrayInputStream(cachedBody);
    }

    @Override
    public boolean isFinished() {
        try {
            return cachedBodyInputStream.available() == 0;
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        return false;
    }

    @Override
    public boolean isReady() {
        return true;
    }

    @Override
    public void setReadListener(ReadListener readListener) {
        throw new UnsupportedOperationException();
    }

    @Override
    public int read() throws IOException {
        return cachedBodyInputStream.read();
    }
}

ContentCachingFilter.java:

@Order(value = Ordered.HIGHEST_PRECEDENCE)
@Component
@WebFilter(filterName = "ContentCachingFilter", urlPatterns = "/*")
public class ContentCachingFilter extends OncePerRequestFilter {

    @Override
    protected void doFilterInternal(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, FilterChain filterChain) throws ServletException, IOException {
        System.out.println("IN  ContentCachingFilter ");
        CachedBodyHttpServletRequest cachedBodyHttpServletRequest = new CachedBodyHttpServletRequest(httpServletRequest);
        filterChain.doFilter(cachedBodyHttpServletRequest, httpServletResponse);
    }
}

I also added the following dependencies to pom:

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-webmvc</artifactId>
    <version>5.2.0.RELEASE</version>
</dependency>

As of now:

• Only the creator of the channel can add a bot.
• Other administrators can't add bots to channels.
• Channel can be public or private (doesn't matter)
• bots can be added only as admins, not members.*

To add the bot to your channel:

• click on the channel name:

• click on admins:

• click on Add Admin:

• search for your bot like @your_bot_name, and click add:**

* In some platforms like mac native telegram client it may look like that you can add bot as a member, but at the end it won't work.
** the bot doesn't need to be in your contact list.

This method does not need to modify dtype or ravel your numpy array.

The core idea is: 1.initialize with one extra row. 2.change the list(which has one more row) to array 3.delete the extra row in the result array e.g.

>>> a = [np.zeros((10,224)), np.zeros((10,))]
>>> np.array(a)
# this will raise error,
ValueError: could not broadcast input array from shape (10,224) into shape (10)

# but below method works
>>> a = [np.zeros((11,224)), np.zeros((10,))]
>>> b = np.array(a)
>>> b[0] = np.delete(b[0],0,0)
>>> print(b.shape,b[0].shape,b[1].shape)
# print result:(2,) (10,224) (10,)

Indeed, it's not necessarily to add one more row, as long as you can escape from the gap stated in @aravk33 and @user707650 's answer and delete the extra item later, it will be fine.

I faced a similar problem, trying to test if jQuery is already present on a page, and if not force it's load, and then execute a function. I tried with @David Hellsing workaround, but with no chance for my needs. In fact, the onload instruction was immediately evaluated, and then the $ usage inside this function was not yet possible (yes, the huggly "$ is not a function." ^^).

So, I referred to this article : https://developer.mozilla.org/fr/docs/Web/Events/load and attached a event listener to my script object.

var script = document.createElement('script');
script.type = "text/javascript";
script.addEventListener("load", function(event) {
    console.log("script loaded :)");
    onjqloaded();
});
script.src = "https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js";
document.getElementsByTagName('head')[0].appendChild(script);

For my needs, it works fine now. Hope this can help others :)

Use the .Select() after grouping:

var agencyContracts = _agencyContractsRepository.AgencyContracts
    .GroupBy(ac => new
                   {
                       ac.AgencyContractID, // required by your view model. should be omited
                                            // in most cases because group by primary key
                                            // makes no sense.
                       ac.AgencyID,
                       ac.VendorID,
                       ac.RegionID
                   })
    .Select(ac => new AgencyContractViewModel
                   {
                       AgencyContractID = ac.Key.AgencyContractID,
                       AgencyId = ac.Key.AgencyID,
                       VendorId = ac.Key.VendorID,
                       RegionId = ac.Key.RegionID,
                       Amount = ac.Sum(acs => acs.Amount),
                       Fee = ac.Sum(acs => acs.Fee)
                   });

That's just a matter of String.contains:

if (input.contains("{item}"))

If you need to know where it occurs, you can use indexOf:

int index = input.indexOf("{item}");
if (index != -1) // -1 means "not found"
{
    ...
}

That's fine for matching exact strings - if you need real patterns (e.g. "three digits followed by at most 2 letters A-C") then you should look into regular expressions.

EDIT: Okay, it sounds like you do want regular expressions. You might want something like this:

private static final Pattern URL_PATTERN =
    Pattern.compile("/\\{[a-zA-Z0-9]+\\}/");

...

if (URL_PATTERN.matches(input).find())

A very simple way of doing this is to use reset_index() method.For a data frame df use the code below:

df.reset_index(inplace=True)

This way, the index will become a column, and by using inplace as True,this become permanent change.

MySQL create function syntax:

DELIMITER //

CREATE FUNCTION GETFULLNAME(fname CHAR(250),lname CHAR(250))
    RETURNS CHAR(250)
    BEGIN
        DECLARE fullname CHAR(250);
        SET fullname=CONCAT(fname,' ',lname);
        RETURN fullname;
    END //

DELIMITER ;

Use This Function In Your Query

SELECT a.*,GETFULLNAME(a.fname,a.lname) FROM namedbtbl as a


SELECT GETFULLNAME("Biswarup","Adhikari") as myname;

Watch this Video how to create mysql function and how to use in your query

Create Mysql Function Video Tutorial

check out this link and then help yourself out.

the basic code is

#create a temp. file
echo "hi " >  t.tmp
# set the file time to 2 hours ago
touch -t 200405121120  t.tmp 
# then check for files
find /admin//dump -type f  -newer t.tmp -print -exec ls -lt {} \; | pg

Put that file in assets.

For project created in Android Studio project you need to create assets folder under the main folder.

Read that file as:

public String loadJSONFromAsset(Context context) {
        String json = null;
        try {
            InputStream is = context.getAssets().open("file_name.json");

            int size = is.available();

            byte[] buffer = new byte[size];

            is.read(buffer);

            is.close();

            json = new String(buffer, "UTF-8");


        } catch (IOException ex) {
            ex.printStackTrace();
            return null;
        }
        return json;

    }

and then you can simply read this string return by this function as

JSONObject obj = new JSONObject(json_return_by_the_function);

For further details regarding JSON see http://www.vogella.com/articles/AndroidJSON/article.html

Hope you will get what you want.

There is actually a comparison of the two in the official WebStorm FAQ. However, the version history of that page shows it was last updated December 13, so I'm not sure if it's maintained.

This is an extract from the FAQs for reference:

What is WebStorm & PhpStorm?

WebStorm & PhpStorm are IDEs (Integrated Development Environment) built on top of JetBrains IntelliJ platform and narrowed for web development.

Which IDE do I need?

PhpStorm is designed to cover all needs of PHP developer including full JavaScript, CSS and HTML support. WebStorm is for hardcore JavaScript developers. It includes features PHP developer normally doesn’t need like Node.JS or JSUnit. However corresponding plugins can be installed into PhpStorm for free.

How often new vesions (sic) are going to be released?

Preliminarily, WebStorm and PhpStorm major updates will be available twice in a year. Minor (bugfix) updates are issued periodically as required.

snip

IntelliJ IDEA vs WebStorm features

IntelliJ IDEA remains JetBrains' flagship product and IntelliJ IDEA provides full JavaScript support along with all other features of WebStorm via bundled or downloadable plugins. The only thing missing is the simplified project setup.

For future reference Python is strongly typed. Unlike other dynamic languages, it will not automagically cast objects from one type or the other (say from str to int) so you must do this yourself. You'll like that in the long-run, trust me!

The answer by Chinmay Kanchi is excellent but I wanted an example of a function which passes and returns a variables/arrays to a C++ code. I though I'd include it here in case it is useful to others.

Passing and returning an integer

The C++ code for a function which takes an integer and adds one to the returned value,

extern "C" int add_one(int i)
{
    return i+1;
}

Saved as file test.cpp, note the required extern "C" (this can be removed for C code). This is compiled using g++, with arguments similar to Chinmay Kanchi answer,

g++ -shared -o testlib.so -fPIC test.cpp

The Python code uses load_library from the numpy.ctypeslib assuming the path to the shared library in the same directory as the Python script,

import numpy.ctypeslib as ctl
import ctypes

libname = 'testlib.so'
libdir = './'
lib=ctl.load_library(libname, libdir)

py_add_one = lib.add_one
py_add_one.argtypes = [ctypes.c_int]
value = 5
results = py_add_one(value)
print(results)

This prints 6 as expected.

Passing and printing an array

You can also pass arrays as follows, for a C code to print the element of an array,

extern "C" void print_array(double* array, int N)
{
    for (int i=0; i<N; i++) 
        cout << i << " " << array[i] << endl;
}

which is compiled as before and the imported in the same way. The extra Python code to use this function would then be,

import numpy as np

py_print_array = lib.print_array
py_print_array.argtypes = [ctl.ndpointer(np.float64, 
                                         flags='aligned, c_contiguous'), 
                           ctypes.c_int]
A = np.array([1.4,2.6,3.0], dtype=np.float64)
py_print_array(A, 3)

where we specify the array, the first argument to print_array, as a pointer to a Numpy array of aligned, c_contiguous 64 bit floats and the second argument as an integer which tells the C code the number of elements in the Numpy array. This then printed by the C code as follows,

1.4
2.6
3.0

In the Notebook

For data exploration in the IPython notebook, my preferred way is this:

sorted(df)

Which will produce an easy to read alphabetically ordered list.

In a code repository

In code I find it more explicit to do

df.columns

Because it tells others reading your code what you are doing.

I seem to be able to get along with simply:

$gpg <path_to_file>

Which outputs like this:

$ gpg /tmp/keys/something.asc 
  pub  1024D/560C6C26 2014-11-26 Something <[email protected]>
  sub  2048g/0C1ACCA6 2014-11-26

The op didn't specify in particular what key info is relevant. This output is all I care about.

The ALTER TABLE MySQL command should do the trick. The following command will change the default character set of your table and the character set of all its columns to UTF8.

ALTER TABLE etape_prospection CONVERT TO CHARACTER SET utf8 COLLATE utf8_general_ci;

This command will convert all text-like columns in the table to the new character set. Character sets use different amounts of data per character, so MySQL will convert the type of some columns to ensure there's enough room to fit the same number of characters as the old column type.

I recommend you read the ALTER TABLE MySQL documentation before modifying any live data.

I know the question is about GCC, but I thought it might be useful to have some information about compilers other compilers as well.

GCC's noinline function attribute is pretty popular with other compilers as well. It is supported by at least:

• Clang (check with __has_attribute(noinline))
• Intel C/C++ Compiler (their documentation is terrible, but I'm certain it works on 16.0+)
• Oracle Solaris Studio back to at least 12.2
• ARM C/C++ Compiler back to at least 4.1
• IBM XL C/C++ back to at least 10.1
• TI 8.0+ (or 7.3+ with --gcc, which will define __TI_GNU_ATTRIBUTE_SUPPORT__)

Additionally, MSVC supports __declspec(noinline) back to Visual Studio 7.1. Intel probably supports it too (they try to be compatible with both GCC and MSVC), but I haven't bothered to verify that. The syntax is basically the same:

__declspec(noinline)
static void foo(void) { }

PGI 10.2+ (and probably older) supports a noinline pragma which applies to the next function:

#pragma noinline
static void foo(void) { }

TI 6.0+ supports a FUNC_CANNOT_INLINE pragma which (annoyingly) works differently in C and C++. In C++, it's similar to PGI's:

#pragma FUNC_CANNOT_INLINE;
static void foo(void) { }

In C, however, the function name is required:

#pragma FUNC_CANNOT_INLINE(foo);
static void foo(void) { }

Cray 6.4+ (and possibly earlier) takes a similar approach, requiring the function name:

#pragma _CRI inline_never foo
static void foo(void) { }

Oracle Developer Studio also supports a pragma which takes the function name, going back to at least Forte Developer 6, but note that it needs to come after the declaration, even in recent versions:

static void foo(void);
#pragma no_inline(foo)

Depending on how dedicated you are, you could create a macro that would work everywhere, but you would need to have the function name as well as the declaration as arguments.

If, OTOH, you're okay with something that just works for most people, you can get away with something which is a little more aesthetically pleasing and doesn't require repeating yourself. That's the approach I've taken for Hedley, where the current version of HEDLEY_NEVER_INLINE looks like:

#if \
  HEDLEY_GNUC_HAS_ATTRIBUTE(noinline,4,0,0) || \
  HEDLEY_INTEL_VERSION_CHECK(16,0,0) || \
  HEDLEY_SUNPRO_VERSION_CHECK(5,11,0) || \
  HEDLEY_ARM_VERSION_CHECK(4,1,0) || \
  HEDLEY_IBM_VERSION_CHECK(10,1,0) || \
  HEDLEY_TI_VERSION_CHECK(8,0,0) || \
  (HEDLEY_TI_VERSION_CHECK(7,3,0) && defined(__TI_GNU_ATTRIBUTE_SUPPORT__))
#  define HEDLEY_NEVER_INLINE __attribute__((__noinline__))
#elif HEDLEY_MSVC_VERSION_CHECK(13,10,0)
#  define HEDLEY_NEVER_INLINE __declspec(noinline)
#elif HEDLEY_PGI_VERSION_CHECK(10,2,0)
#  define HEDLEY_NEVER_INLINE _Pragma("noinline")
#elif HEDLEY_TI_VERSION_CHECK(6,0,0)
#  define HEDLEY_NEVER_INLINE _Pragma("FUNC_CANNOT_INLINE;")
#else
#  define HEDLEY_NEVER_INLINE HEDLEY_INLINE
#endif

If you don't want to use Hedley (it's a single public domain / CC0 header) you can convert the version checking macros without too much effort, but more than I'm willing to put in ?.

You might want to think about aspect-oriented programming. You don't want to litter your code with timings. You want to be able to turn them off and on declaratively.

If you use Spring, take a look at their MethodInterceptor class.

Here is one neat way with easy to understand algorithm.

import copy

nums = [2,3,4,5]
subsets = [[]]

for n in nums:
    prev = copy.deepcopy(subsets)
    [k.append(n) for k in subsets]
    subsets.extend(prev)

print(subsets) 
print(len(subsets))

# [[2, 3, 4, 5], [3, 4, 5], [2, 4, 5], [4, 5], [2, 3, 5], [3, 5], [2, 5], [5], 
# [2, 3, 4], [3, 4], [2, 4], [4], [2, 3], [3], [2], []]

# 16 (2^len(nums))

Yes, you should use semicolons after every statement in JavaScript.

You can use Zend_Debug::Dump($select->assemble()); to get the SQL query.

Or you can enable Zend DB FirePHP profiler which will get you all queries in a neat format in Firebug (even UPDATE statements).

EDIT: Profiling with FirePHP also works also in FF6.0+ (not only in FF3.0 as suggested in link)

You need to go one level deeper in what you are retrieving.

Dim tbl As ListObject
Set tbl = ActiveSheet.ListObjects("MyTable")
MsgBox tbl.Range.Rows.Count
MsgBox tbl.HeaderRowRange.Rows.Count
MsgBox tbl.DataBodyRange.Rows.Count
Set tbl = Nothing

More information at:

ListObject Interface

just use onkeypress event like below:

<input type="text" name="onlyalphabet" onkeypress="return (event.charCode > 64 && event.charCode < 91) || (event.charCode > 96 && event.charCode < 123)">

The function you need is CInt.

ie CInt(PrinterLabel)

See Type Conversion Functions (Visual Basic) on MSDN

Edit: Be aware that CInt and its relatives behave differently in VB.net and VBScript. For example, in VB.net, CInt casts to a 32-bit integer, but in VBScript, CInt casts to a 16-bit integer. Be on the lookout for potential overflows!

Check remote branch list:

git branch -a

Switch to another Branch:

git checkout -b <local branch name> <Remote branch name>
Example: git checkout -b Dev_8.4 remotes/gerrit/Dev_8.4

Check local Branch list:

git branch

Update everything:

git pull

The problem is

listModel.addElement(listaRosa.getSelectedValue());
listModel.removeElement(listaRosa.getSelectedValue());

you may be adding an element and immediatly removing it since both add and remove operations are on the same listModel.

Try

private void aggiungiTitolareButtonActionPerformed(java.awt.event.ActionEvent evt) {                                                       

    DefaultListModel lm2 = (DefaultListModel) listaTitolari.getModel();
    DefaultListModel lm1  = (DefaultListModel) listaRosa.getModel();
    if(lm2 == null)
    {
        lm2 = new DefaultListModel();
        listaTitolari.setModel(lm2);
    }
    lm2.addElement(listaTitolari.getSelectedValue());
    lm1.removeElement(listaTitolari.getSelectedValue());        
} 

From a file:

import re
sep = '...'

with open("requirements.txt") as file_in:
    lines = []
    for line in file_in:
        res = line.split(sep, 1)[0]
        print(res)

if it does not matter to have those element ids appended to the url, you should consider taking a look at this link:

Angular 2 - Anchor Links to Element on Current Page

// html_x000D_
// add (click) event on element_x000D_
<a (click)="scroll({{any-element-id}})">Scroll</a>_x000D_
_x000D_
// in ts file, do this_x000D_
scroll(sectionId) {_x000D_
let element = document.getElementById(sectionId);_x000D_
_x000D_
  if(element) {_x000D_
    element.scrollIntoView(); // scroll to a particular element_x000D_
  }_x000D_
 }

There are 2 possibilities.

You really don't have Label property.

You need to call appropriate GetProperty overload and pass the correct binding flags, e.g. BindingFlags.Public | BindingFlags.Instance

If your property is not public, you will need to use BindingFlags.NonPublic or some other combination of flags which fits your use case. Read the referenced API docs to find the details.

EDIT:

ooops, just noticed you call GetProperty on typeof(MyClass). typeof(MyClass) is Type which for sure has no Label property.

Determine if string is a date, even if string is a non-standard format

(strtotime doesn't accept any custom format)

<?php
function validateDateTime($dateStr, $format)
{
    date_default_timezone_set('UTC');
    $date = DateTime::createFromFormat($format, $dateStr);
    return $date && ($date->format($format) === $dateStr);
}

// These return true
validateDateTime('2001-03-10 17:16:18', 'Y-m-d H:i:s');
validateDateTime('2001-03-10', 'Y-m-d');
validateDateTime('2001', 'Y');
validateDateTime('Mon', 'D');
validateDateTime('March 10, 2001, 5:16 pm', 'F j, Y, g:i a');
validateDateTime('March 10, 2001, 5:16 pm', 'F j, Y, g:i a');
validateDateTime('03.10.01', 'm.d.y');
validateDateTime('10, 3, 2001', 'j, n, Y');
validateDateTime('20010310', 'Ymd');
validateDateTime('05-16-18, 10-03-01', 'h-i-s, j-m-y');
validateDateTime('Monday 8th of August 2005 03:12:46 PM', 'l jS \of F Y h:i:s A');
validateDateTime('Wed, 25 Sep 2013 15:28:57', 'D, d M Y H:i:s');
validateDateTime('17:03:18 is the time', 'H:m:s \i\s \t\h\e \t\i\m\e');
validateDateTime('17:16:18', 'H:i:s');

// These return false
validateDateTime('2001-03-10 17:16:18', 'Y-m-D H:i:s');
validateDateTime('2001', 'm');
validateDateTime('Mon', 'D-m-y');
validateDateTime('Mon', 'D-m-y');
validateDateTime('2001-13-04', 'Y-m-d');

In case when the enum members have different values, you can apply something like this:

public static MyGender? MapToMyGender(this Gender gender)
{
    return gender switch
    {
        Gender.Male => MyGender.Male,
        Gender.Female => MyGender.Female,
        Gender.Unknown => null,
        _ => throw new InvalidEnumArgumentException($"Invalid gender: {gender}")
    };
}

Then you can call: var myGender = gender.MapToMyGender();

Update: This previous code works only with C# 8. For older versions of C#, you can use the switch statement instead of the switch expression:

public static MyGender? MapToMyGender(this Gender gender)
{
    switch (gender)
    {
        case Gender.Male: 
            return MyGender.Male;
        case Gender.Female:
            return MyGender.Female;
        case Gender.Unknown:
            return null;
        default:
            throw new InvalidEnumArgumentException($"Invalid gender: {gender}")
    };
}

The answer is simple.

As I just figured, in case you have a model fitted on multiple linear regression, the above mentioned solution won't work.

You have to create your line manually as a dataframe that contains predicted values for your original dataframe (in your case data).

It would look like this:

# read dataset
df = mtcars

# create multiple linear model
lm_fit <- lm(mpg ~ cyl + hp, data=df)
summary(lm_fit)

# save predictions of the model in the new data frame 
# together with variable you want to plot against
predicted_df <- data.frame(mpg_pred = predict(lm_fit, df), hp=df$hp)

# this is the predicted line of multiple linear regression
ggplot(data = df, aes(x = mpg, y = hp)) + 
  geom_point(color='blue') +
  geom_line(color='red',data = predicted_df, aes(x=mpg_pred, y=hp))

# this is predicted line comparing only chosen variables
ggplot(data = df, aes(x = mpg, y = hp)) + 
  geom_point(color='blue') +
  geom_smooth(method = "lm", se = FALSE)

I keep this build-and-run script handy, whenever I am working from command line:

#!/usr/bin/env bash

echo "Package: $PACKAGE"

echo "Building the project with tasks: $TASKS"

echo "Installing $APK_LOCATION"
adb install $APK_LOCATION

echo "Starting $ACTIVITY"
adb shell am start -n $PACKAGE/$ACTIVITY

a short summary:

track by is used in order to link your data with the DOM generation (and mainly re-generation) made by ng-repeat.

when you add track by you basically tell angular to generate a single DOM element per data object in the given collection

this could be useful when paging and filtering, or any case where objects are added or removed from ng-repeat list.

usually, without track by angular will link the DOM objects with the collection by injecting an expando property - $$hashKey - into your JavaScript objects, and will regenerate it (and re-associate a DOM object) with every change.

full explanation:

An alternative to get a byte array is to encode the string in ascii: b=s.encode('ascii').

Got this error also....

it occurs when save to filepath contains invalid characters, in my case:

path = "C:/somefolder/anotherfolder\file.xls";

Note the existence of both \ and /

*Also may occur if trying to save to directory which doesn't already exist.

Foreign key and check constraints have the concept of being trusted or untrusted, as well as being enabled and disabled. See the MSDN page for ALTER TABLE for full details.

WITH CHECK is the default for adding new foreign key and check constraints, WITH NOCHECK is the default for re-enabling disabled foreign key and check constraints. It's important to be aware of the difference.

Having said that, any apparently redundant statements generated by utilities are simply there for safety and/or ease of coding. Don't worry about them.

Also worth noting the following from a document by the R Core Team summarizing changes in versions of R after v3.5.0 (here):

R has new serialization format (version 3) which supports custom serialization of ALTREP framework objects... Serialized data in format 3 cannot be read by versions of R prior to version 3.5.0.

I encountered this issue when I saved a workspace in v3.6.0, and then shared the file with a colleague that was using v3.4.2. I was able to resolve the issue by adding "version=2" to my save function.

To run tests with node/npm without installing Mocha globally, you can do this:

• Install Mocha locally to your project (npm install mocha --save-dev)

• Optionally install an assertion library (npm install chai --save-dev)

• In your package.json, add a section for scripts and target the mocha binary

"scripts": {
  "test": "node ./node_modules/mocha/bin/mocha"
}

• Put your spec files in a directory named /test in your root directory

• In your spec files, import the assertion library

var expect = require('chai').expect;

• You don't need to import mocha, run mocha.setup, or call mocha.run()

• Then run the script from your project root:

npm test

You can just do this:

long currentTime = (long)(NSTimeInterval)([[NSDate date] timeIntervalSince1970]);

this will return a value en milliseconds, so if you multiply the resulting value by 1000 (as suggested my Eimantas) you'll overflow the long type and it'll result in a negative value.

For example, if I run that code right now, it'll result in

currentTime = 1357234941

and

currentTime /seconds / minutes / hours / days = years
1357234941 / 60 / 60 / 24 / 365 = 43.037637652207

Go from this:

config.Routes.MapHttpRoute("API Default", "api/{controller}/{id}",
            new { id = RouteParameter.Optional });

To this:

config.Routes.MapHttpRoute("API Default", "api/{controller}/{action}/{id}",
            new { id = RouteParameter.Optional });

Hence, you can now specify which action (method) you want to send your HTTP request to.

I tried this in a self hosted WEB API service application and it works like a charm :)

One classic root cause for this message is:

• when the repo has been initialized (git init lis4368/assignments),
• but no commit has ever been made

Ie, if you don't have added and committed at least once, there won't be a local master branch to push to.

Try first to create a commit:

• either by adding (git add .) then git commit -m "first commit"
  (assuming you have the right files in place to add to the index)
• or by create a first empty commit: git commit --allow-empty -m "Initial empty commit"

And then try git push -u origin master again.

See "Why do I need to explicitly push a new branch?" for more.

For the record to go back and forth in basic python3:

a = 10
bin(a)
# '0b1010'

int(bin(a), 2)
# 10
eval(bin(a))
# 10

You can try the following regular expression:

\r?\n

Code:

String input = "\nab\n\n    \n\ncd\nef\n\n\n\n\n";
String[] lines = input.split("\\r?\\n", -1);
int n = 1;
for(String line : lines) {
    System.out.printf("\tLine %02d \"%s\"%n", n++, line);
}

Output:

Line 01 ""
Line 02 "ab"
Line 03 ""
Line 04 "    "
Line 05 ""
Line 06 "cd"
Line 07 "ef"
Line 08 ""
Line 09 ""
Line 10 ""
Line 11 ""
Line 12 ""

You can also use the data-interval attribute eg. <div class="carousel" data-interval="10000">

I usually use Task to interact with Winforms and simple background worker to make it not freezing the UI. here an example when I prefer using Task

private async void buttonDownload_Click(object sender, EventArgs e)
{
    buttonDownload.Enabled = false;
    await Task.Run(() => {
        using (var client = new WebClient())
        {
            client.DownloadFile("http://example.com/file.mpeg", "file.mpeg");
        }
    })
    buttonDownload.Enabled = true;
}

VS

private void buttonDownload_Click(object sender, EventArgs e)
{
    buttonDownload.Enabled = false;
    Thread t = new Thread(() =>
    {
        using (var client = new WebClient())
        {
            client.DownloadFile("http://example.com/file.mpeg", "file.mpeg");
        }
        this.Invoke((MethodInvoker)delegate()
        {
            buttonDownload.Enabled = true;
        });
    });
    t.IsBackground = true;
    t.Start();
}

the difference is you don't need to use MethodInvoker and shorter code.

Try this code. it worked for me.

 function getInvoiceID(url, invoiceId) {
    return $.ajax({
        type: 'POST',
        url: url,
        data: { invoiceId: invoiceId },
        async: false,
    });
}
function isInvoiceIdExists(url, invoiceId) {
    $.when(getInvoiceID(url, invoiceId)).done(function (data) {
        if (!data) {

        }
    });
}

keep the currently selected drop down value with chosen jquery in a global variable before writing the drop down 'on change' action function. If you want to set previous value in the function you can use the global variable.

//global variable
var previousValue=$("#dropDownList").val();
$("#dropDownList").change(function () {
BootstrapDialog.confirm(' Are you sure you want to continue?',
  function (result) {
  if (result) {
     return true;
  } else {
      $("#dropDownList").val(previousValue).trigger('chosen:updated');  
     return false;
         }
  });
});

This doesn't directly answer your question, but here's a generic function which will create a URL that contains query string parameters. The parameters (names and values) are safely escaped for inclusion in a URL.

function buildUrl(url, parameters){
  var qs = "";
  for(var key in parameters) {
    var value = parameters[key];
    qs += encodeURIComponent(key) + "=" + encodeURIComponent(value) + "&";
  }
  if (qs.length > 0){
    qs = qs.substring(0, qs.length-1); //chop off last "&"
    url = url + "?" + qs;
  }
  return url;
}

// example:
var url = "http://example.com/";

var parameters = {
  name: "George Washington",
  dob: "17320222"
};

console.log(buildUrl(url, parameters));
// => http://www.example.com/?name=George%20Washington&dob=17320222

As written by Dave Butenhof himself:

"The biggest of all the big problems with recursive mutexes is that they encourage you to completely lose track of your locking scheme and scope. This is deadly. Evil. It's the "thread eater". You hold locks for the absolutely shortest possible time. Period. Always. If you're calling something with a lock held simply because you don't know it's held, or because you don't know whether the callee needs the mutex, then you're holding it too long. You're aiming a shotgun at your application and pulling the trigger. You presumably started using threads to get concurrency; but you've just PREVENTED concurrency."

A static library is like a bookstore, and a shared library is like... a library. With the former, you get your own copy of the book/function to take home; with the latter you and everyone else go to the library to use the same book/function. So anyone who wants to use the (shared) library needs to know where it is, because you have to "go get" the book/function. With a static library, the book/function is yours to own, and you keep it within your home/program, and once you have it you don't care where or when you got it.

:last-child will not work if the element is not the VERY LAST element

In addition to Harry's answer, I think it's crucial to add/emphasize that :last-child will not work if the element is not the VERY LAST element in a container. For whatever reason it took me hours to realize that, and even though Harry's answer is very thorough I couldn't extract that information from "The last-child selector is used to select the last child element of a parent."

Suppose this is my selector: a:last-child {}

This works:

<div>
    <a></a>
    <a>This will be selected</a>
</div>

This doesn't:

<div>
    <a></a>
    <a>This will no longer be selected</a>
    <div>This is now the last child :'( </div>
</div>

It doesn't because the a element is not the last element inside its parent.

It may be obvious, but it was not for me...

The easiest way to format a TimeSpan is to add it to a DateTime and format that:

string formatted = (DateTime.Today + dateDifference).ToString("HH 'hrs' mm 'mins' ss 'secs'");

This works as long as the time difference is not more than 24 hours.

The Today property returns a DateTime value where the time component is zero, so the time component of the result is the TimeSpan value.

In a previous project I found that changing from *-imports to specific imports reduced compilation time by half (from about 10 minutes to about 5 minutes). The *-import makes the compiler search each of the packages listed for a class matching the one you used. While this time can be small, it adds up for large projects.

A side affect of the *-import was that developers would copy and paste common import lines rather than think about what they needed.

One of these :

    $ip = $_SERVER['REMOTE_ADDR'];
    $ip = $_SERVER['HTTP_CLIENT_IP'];
    $ip = $_SERVER['HTTP_X_FORWARDED_FOR'];
    $ip = $_SERVER['HTTP_X_FORWARDED'];
    $ip = $_SERVER['HTTP_FORWARDED_FOR'];
    $ip = $_SERVER['HTTP_FORWARDED'];

As addition to other answers, one can write something else if variable is None like this:

{{ variable or '' }}

You can use the function outer() to generate it.

Have a look at the demo for the function persp(), which is a base graphics function to draw perspective plots for surfaces.

Here is their first example:

x <- seq(-10, 10, length.out = 50)  
y <- x  
rotsinc <- function(x,y) {
    sinc <- function(x) { y <- sin(x)/x ; y[is.na(y)] <- 1; y }  
    10 * sinc( sqrt(x^2+y^2) )  
}

z <- outer(x, y, rotsinc)  
persp(x, y, z)

The same applies to surface3d():

require(rgl)  
surface3d(x, y, z)

You didn't specify what the error you're seeing is.

Is the problem that gcc is giving you an error, or that you can't run gcc at all?

If it's the latter, the most likely explanation is that you didn't check "UNIX Development Support" when you installed the development tools, so the command-line executables aren't installed in your path. Re-install the development tools, and make sure to click "customize" and check that box.

Try this..

select starttime,endtime, case
  when DATEDIFF(minute,starttime,endtime) < 60  then DATEDIFF(minute,starttime,endtime) 
  when DATEDIFF(minute,starttime,endtime) >= 60
  then '60,'+ cast( (cast(DATEDIFF(minute,starttime,endtime) as int )-60) as nvarchar(50) )
end from TestTable123416

All You need is DateDiff..

Enums are just like Classes in that they are typed. Your current code just checks if it is an Enum without specifying what type of Enum it is a part of.

Because you haven't specified the type of the enum, you will have to use reflection to find out what the list of enum values is.

You can do it like so:

enumValue.getDeclaringClass().getEnumConstants() 

This will return an array of Enum objects, with each being one of the available options.

The answer has been copied from this tutorial I wrote at LearnOpenCV.com explaining various parameters of SimpleBlobDetector. You can find additional details about the parameters in the tutorial.

You can do a post/get using a library which allows you to use HttpClient with strongly-typed callbacks.

The data and the error are available directly via these callbacks.

The library is called angular-extended-http-client.

angular-extended-http-client library on GitHub

angular-extended-http-client library on NPM

Very easy to use.

Traditional approach

In the traditional approach you return Observable<HttpResponse<T>> from Service API. This is tied to HttpResponse.

With this approach you have to use .subscribe(x => ...) in the rest of your code.

This creates a tight coupling between the http layer and the rest of your code.

Strongly-typed callback approach

You only deal with your Models in these strongly-typed callbacks.

Hence, The rest of your code only knows about your Models.

Sample usage

The strongly-typed callbacks are

Success:

• IObservable<T>
• IObservableHttpResponse
• IObservableHttpCustomResponse<T>

Failure:

• IObservableError<TError>
• IObservableHttpError
• IObservableHttpCustomError<TError>

Add package to your project and in your app module

import { HttpClientExtModule } from 'angular-extended-http-client';

and in the @NgModule imports

  imports: [
    .
    .
    .
    HttpClientExtModule
  ],

Your Models

export class SearchModel {
    code: string;
}

//Normal response returned by the API.
export class RacingResponse {
    result: RacingItem[];
}

//Custom exception thrown by the API.
export class APIException {
    className: string;
}

Your Service

In your Service, you just create params with these callback types.

Then, pass them on to the HttpClientExt's get method.

import { Injectable, Inject } from '@angular/core'
import { SearchModel, RacingResponse, APIException } from '../models/models'
import { HttpClientExt, IObservable, IObservableError, ResponseType, ErrorType } from 'angular-extended-http-client';
.
.

@Injectable()
export class RacingService {

    //Inject HttpClientExt component.
    constructor(private client: HttpClientExt, @Inject(APP_CONFIG) private config: AppConfig) {

    }

    //Declare params of type IObservable<T> and IObservableError<TError>.
    //These are the success and failure callbacks.
    //The success callback will return the response objects returned by the underlying HttpClient call.
    //The failure callback will return the error objects returned by the underlying HttpClient call.
    searchRaceInfo(model: SearchModel, success: IObservable<RacingResponse>, failure?: IObservableError<APIException>) {
        let url = this.config.apiEndpoint;

        this.client.post<SearchModel, RacingResponse>(url, model, 
                                                      ResponseType.IObservable, success, 
                                                      ErrorType.IObservableError, failure);
    }
}

Your Component

In your Component, your Service is injected and the searchRaceInfo API called as shown below.

  search() {    


    this.service.searchRaceInfo(this.searchModel, response => this.result = response.result,
                                                  error => this.errorMsg = error.className);

  }

Both, response and error returned in the callbacks are strongly typed. Eg. response is type RacingResponse and error is APIException.

I have another solution. If Alpha and Beta are your only extra class then why not make a static variable with the image of the class.

Like in Alpha class :

public class Alpha{
        public static Alpha alpha;
        public Alpha(){
                this.alpha = this;
}

Now you you can call the function in Beta class by just using these lines :

new Alpha();
Alpha.alpha.DoSomethingAlpha();

on my pc I had the same problem and it was because in properties -> security I didn't have the ownership of the file...

I think your problem was that you thought that the installer in Android SDK Manager would actually INSTALL the Intel HAXM. But the hook is that it WILL NOT INSTALL it. What it does is extracts the files needed for (really) install Intel HAXM.

I found that out when I got the same problem and then read this in Intel's web page:

Downloading through Android* SDK Manager

... Other steps ...

5) The SDK Manager will download the installer to the "extras" directory, under the main SDK directory. Even though the SDK manager says "Installed" it actually means that the Intel HAXM executable was downloaded. You will still need to run the installer from the "extras" directory to get it installed.

6) Run the installer inside the /sdk/extras/intel/Hardware_Accelerated_Execution_Manager/ directory and follow the installation instructions for your platform.

So all I needed to do was go to folder where my Android SDK was, opened that folder (sdk_location/sdk/extras/intel/Hardware_Accelerated_Execution_Manager) and run the silent_install.bat.

After this when I launched my emulator, it said this:

HAXM is working and emulator runs fast virt mode

and everything works as should!

You can also use some useful parameters with silent_install.bat:

• -v Print HAXM version
• -c Check VT/NX capability of the platform
• -h Print usage

Use the constructor of string which accepts a char[]

char[] c = ...;
string s = new string(c);

EDIT (2018): The edited sibling answer by @xinyongCheng is a simpler approach, and should be the accepted answer.

Your approach would be reasonable if you knew the bytes are in the platform's default charset. In your example, this is true because k.getBytes() returns the bytes in the platform's default charset.

More frequently, you'll want to specify the encoding. However, there's a simpler way to do that than the question you linked. The String API provides methods that converts between a String and a byte[] array in a particular encoding. These methods suggest using CharsetEncoder/CharsetDecoder "when more control over the decoding [encoding] process is required."

To get the bytes from a String in a particular encoding, you can use a sibling getBytes() method:

byte[] bytes = k.getBytes( StandardCharsets.UTF_8 );

To put bytes with a particular encoding into a String, you can use a different String constructor:

String v = new String( bytes, StandardCharsets.UTF_8 );

Note that ByteBuffer.array() is an optional operation. If you've constructed your ByteBuffer with an array, you can use that array directly. Otherwise, if you want to be safe, use ByteBuffer.get(byte[] dst, int offset, int length) to get bytes from the buffer into a byte array.

Return a FileResult or FileStreamResult from your action, depending on whether the file exists or you create it on the fly.

public ActionResult GetPdf(string filename)
{
    return File(filename, "application/pdf", Server.UrlEncode(filename));
}

you would have to write down some method to create a temporary array and then copy it like

public String[] increaseArray(String[] theArray, int increaseBy)  
{  
    int i = theArray.length;  
    int n = ++i;  
    String[] newArray = new String[n];  
    for(int cnt=0;cnt<theArray.length;cnt++)
    {  
        newArray[cnt] = theArray[cnt];  
    }  
    return newArray;  
}  

or The ArrayList would be helpful to resolve your problem.

Well, from my understanding, simply for matching this format in a given string, I prefer this regular expression:

pattern='[0-9|/]+'

to match the format in a more strict way, the following works:

pattern='(?:[0-9]{2}/){2}[0-9]{2}'

Personally, I cannot agree with unutbu's answer since sometimes we use regular expression for "finding" and "extract", not only "validating".

While the other answer is correct, here's the fastest way to just go ahead and configure Meld as your visual diff tool. Just copy/paste this:

git config --global diff.tool meld
git config --global difftool.prompt false

Now run git difftool in a directory and Meld will be launched for each different file.

Side note: Meld is surprisingly slow at comparing CSV files, and no Linux diff tool I've found is faster than this Windows tool called Compare It! (last updated in 2010).

Let's say if want to Receive Data from ViewControllerB to ViewControllerA

ViewControllerA (Receiver)

import UIKit

class ViewControllerA: UIViewController  {

    override func viewDidLoad() {
        super.viewDidLoad()

        //MARK: - - - - - Code for Passing Data through Notification Observer - - - - -
        // add observer in controller(s) where you want to receive data
        NotificationCenter.default.addObserver(self, selector: #selector(self.methodOfReceivedNotification(notification:)), name: Notification.Name("NotificationIdentifier"), object: nil)
    }

    //MARK: - - - - - Method for receiving Data through Post Notificaiton - - - - -
    @objc func methodOfReceivedNotification(notification: Notification) {
        print("Value of notification : ", notification.object ?? "")
    }
}

ViewControllerB (Sender)

import UIKit

class ViewControllerB: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()

        //MARK: - - - - - Set data for Passing Data Post Notification - - - - -
        let objToBeSent = "Test Message from Notification"
        NotificationCenter.default.post(name: Notification.Name("NotificationIdentifier"), object: objToBeSent)
    }

}

You don't want git revert. That undoes a previous commit. You want git checkout to get git's version of the file from master.

git checkout -- filename.txt

In general, when you want to perform a git operation on a single file, use -- filename.

• git-revert Documentation

2020 Update

Git introduced a new command git restore in version 2.23.0. Therefore, if you have git version 2.23.0+, you can simply git restore filename.txt - which does the same thing as git checkout -- filename.txt. The docs for this command do note that it is currently experimental.

Answer for Python beginners

In simpler words:

1. The key= parameter of sort requires a key function (to be applied to be objects to be sorted) rather than a single key value and
2. that is just what operator.itemgetter(1) will give you: A function that grabs the first item from a list-like object.

(More precisely those are callables, not functions, but that is a difference that can often be ignored.)

@JAB's answer is fast and concise. But it changes the DataFrame you are trying to sort, which you may or may not want.

_{(Note: You almost certainly will want it, because your date columns should be dates, not strings!)}

In the unlikely event that you don't want to change the dates into dates, you can also do it a different way.

First, get the index from your sorted Date column:

In [25]: pd.to_datetime(df.Date).order().index
Out[25]: Int64Index([0, 2, 1], dtype='int64')

Then use it to index your original DataFrame, leaving it untouched:

In [26]: df.ix[pd.to_datetime(df.Date).order().index]
Out[26]: 
        Date Symbol
0 2015-02-20      A
2 2015-08-21      A
1 2016-01-15      A

Magic!

Note: for Pandas versions 0.20.0 and later, use loc instead of ix, which is now deprecated.

From MSDN
$0 - "Substitutes the last substring matched by group number number (decimal)."

In .NET Regular expressions group 0 is always the entire match. For a literal $ you need to

string value = Regex.Replace("%PolicyAmount%", "%PolicyAmount%", @"$$0", RegexOptions.IgnoreCase);

The following VBA code should get you started. It will copy all of the data in the original workbook to a new workbook, but it will have added 1 to each value, and all blank cells will have been ignored.

Option Explicit

Public Sub exportDataToNewBook()
    Dim rowIndex As Integer
    Dim colIndex As Integer
    Dim dataRange As Range
    Dim thisBook As Workbook
    Dim newBook As Workbook
    Dim newRow As Integer
    Dim temp

    '// set your data range here
    Set dataRange = Sheet1.Range("A1:B100")

    '// create a new workbook
    Set newBook = Excel.Workbooks.Add

    '// loop through the data in book1, one column at a time
    For colIndex = 1 To dataRange.Columns.Count
        newRow = 0
        For rowIndex = 1 To dataRange.Rows.Count
            With dataRange.Cells(rowIndex, colIndex)

            '// ignore empty cells
            If .value <> "" Then
                newRow = newRow + 1
                temp = doSomethingWith(.value)
                newBook.ActiveSheet.Cells(newRow, colIndex).value = temp
                End If

            End With
        Next rowIndex
    Next colIndex
End Sub

Private Function doSomethingWith(aValue)

    '// This is where you would compute a different value
    '// for use in the new workbook
    '// In this example, I simply add one to it.
    aValue = aValue + 1

    doSomethingWith = aValue
End Function

Why can't you just check it yourself and throw an exception if that is what you want.

    try {
        for (int i = 0; i < tab.length; i++) {
            tab[i] = 1.0 / tab[i];

            if (tab[i] == Double.POSITIVE_INFINITY ||
                    tab[i] == Double.NEGATIVE_INFINITY)
                throw new ArithmeticException();
        }
    } catch (ArithmeticException ae) {
        System.out.println("ArithmeticException occured!");
    }

System.Diagnostics.Stopwatch is designed for this task.

Instead of working with positioning and padding/margin and without knowing the header's size, there's a way to keep the header fixed by playing with the scroll.

See the this plunker with a fixed header:

<html lang="en" style="height: 100%">
<body style="height: 100%">
<div style="height: 100%; overflow: hidden">
  <div>Header</div>
  <div style="height: 100%; overflow: scroll">Content - very long Content...

The key here is a mix of height: 100% with overflow.

See a specific question on removing the scroll from the header here and answer here.

You could use JavaScript and trigger the hidden file input when the button input has been clicked.

http://jsfiddle.net/gregorypratt/dhyzV/ - simple

http://jsfiddle.net/gregorypratt/dhyzV/1/ - fancier with a little JQuery

Or, you could style a div directly over the file input and set pointer-events in CSS to none to allow the click events to pass through to the file input that is "behind" the fancy div. This only works in certain browsers though; http://caniuse.com/pointer-events

In code:

editText.setEnabled(false);

Or, in XML:

android:editable="false"

Don't forget URNs. URIs and URLs are both URNs. URLs have a location:

URI: foo
URL: http://some.domain.com/foo
URL: http://some.domain.com:8080/foo
URL: ftp://some.domain.com/foo

They're all URNs.

The solution to when you're using XMLWriter (native to PHP 5.2.x<) is using $xml->startElement('itemName'); this will replace the arrays key.

First thing you should check is that whether the image exists in the root directory or not. This is mostly due to image with height = 0. Which means that cv2.imread(imageName) is not reading the image.

Use collectl which has extensive process I/O monitoring including monitoring threads.

Be warned that there are I/O counters for I/O being written to cache and I/O going to disk. collectl reports them separately. If you're not careful you can misinterpret the data. See http://collectl.sourceforge.net/Process.html

Of course, it shows a lot more than just process stats because you'd want one tool to provide everything rather than a bunch of different one that displays everything in different formats, right?

The result of your code will be the same. The reason is that the two incrementation operations can be seen as two distinct function calls. Both functions cause an incrementation of the variable, and only their return values are different. In this case, the return value is just thrown away, which means that there's no distinguishable difference in the output.

However, under the hood there's a difference: The post-incrementation i++ needs to create a temporary variable to store the original value of i, then performs the incrementation and returns the temporary variable. The pre-incrementation ++i doesn't create a temporary variable. Sure, any decent optimization setting should be able to optimize this away when the object is something simple like an int, but remember that the ++-operators are overloaded in more complicated classes like iterators. Since the two overloaded methods might have different operations (one might want to output "Hey, I'm pre-incremented!" to stdout for example) the compiler can't tell whether the methods are equivalent when the return value isn't used (basically because such a compiler would solve the unsolvable halting problem), it needs to use the more expensive post-incrementation version if you write myiterator++.

Three reasons why you should pre-increment:

1. You won't have to think about whether the variable/object might have an overloaded post-incrementation method (for example in a template function) and treat it differently (or forget to treat it differently).
2. Consistent code looks better.
3. When someone asks you "Why do you pre-increment?" you'll get the chance to teach them about the halting problem and theoretical limits of compiler optimization. :)

I think it's all personal preference. My preferences come from using NHibernate, in .NET, with SQL Server, so they probably differ from what others use.

• Databases: The application that's being used.. ex: Stackoverflow
• Collections: Singular in name, what it's going to be a collection of, ex: Question
• Document fields, ex: MemberFirstName

Honestly, it doesn't matter too much, as long as it's consistent for the project. Just get to work and don't sweat the details :P

@Override
    public boolean onTouch(View v, MotionEvent event) {
       float x = event.getX();
       float y = event.getY();
       return true;
    }

Update a row or column of a table

$update = "UPDATE daily_patients SET queue_status = 'pending' WHERE doctor_id = $room_no and serial_number= $serial_num";

if ($con->query($update) === TRUE) {
    echo "Record updated successfully";
} else {
    echo "Error updating record: " . $con->error;
}

file_name=test.log

# set first K lines:
K=1000

# line count (N): 
N=$(wc -l < $file_name)

# length of the bottom file:
L=$(( $N - $K ))

# create the top of file: 
head -n $K $file_name > top_$file_name

# create bottom of file: 
tail -n $L $file_name > bottom_$file_name

Also, on second thought, split will work in your case, since the first split is larger than the second. Split puts the balance of the input into the last split, so

split -l 300000 file_name

will output xaa with 300k lines and xab with 100k lines, for an input with 400k lines.

OpenWebKitSharp gives you full control over WebKit Nightly, which is very close to webkit in terms of performance and compatibility. Chrome uses WebKit Chromium engine, while WebKit.NET uses Cairo and OpenWebKitSharp Nightly. Chromium should be the best of these builds, while at 2nd place should come Nightly and that's why I suggest OpenWebKitSharp.

string.substring(start,end)

where

start = Required. The position where to start the extraction. First character is at index 0`.

end = Optional. The position (up to, but not including) where to end the extraction. If omitted, it extracts the rest of the string.

    var string = "var1/var2/var3";

    start   = string.lastIndexOf('/');  //console.log(start); o/p:- 9
    end     = string.length;            //console.log(end);   o/p:- 14

    var string_before_last_slash = string.substring(0, start);
    console.log(string_before_last_slash);//o/p:- var1/var2

    var string_after_last_slash = string.substring(start+1, end);
    console.log(string_after_last_slash);//o/p:- var3

OR

    var string_after_last_slash = string.substring(start+1);
    console.log(string_after_last_slash);//o/p:- var3

Here is a comparison with np.einsum to show how the indices are projected

np.allclose(np.einsum('ijk,ijk->ijk', a,b), a*b)        # True 
np.allclose(np.einsum('ijk,ikl->ijl', a,b), a@b)        # True
np.allclose(np.einsum('ijk,lkm->ijlm',a,b), a.dot(b))   # True
