String[] errorSoon = { "foo", "bar" };

-- or --

String[] errorSoon = new String[2];
errorSoon[0] = "foo";
errorSoon[1] = "bar";

It's a good idea that using two arc command to draw a full circle.

usually, I use ellipse or circle element to draw a full circle.

Another way is using a ResourceBundle. Basically you get the bundle using its name without the '.properties'

private static final ResourceBundle resource = ResourceBundle.getBundle("config");

And you recover any value using this:

private final String prop = resource.getString("propName");

Rendering happens after change detection. To force change detection, so that component property values that have changed get propagated to the DOM (and then the browser will render those changes in the view), here are some options:

• ApplicationRef.tick() - similar to Angular 1's $rootScope.$digest() -- i.e., check the full component tree
• NgZone.run(callback) - similar to $rootScope.$apply(callback) -- i.e., evaluate the callback function inside the Angular 2 zone. I think, but I'm not sure, that this ends up checking the full component tree after executing the callback function.
• ChangeDetectorRef.detectChanges() - similar to $scope.$digest() -- i.e., check only this component and its children

You will need to import and then inject ApplicationRef, NgZone, or ChangeDetectorRef into your component.

For your particular scenario, I would recommend the last option if only a single component has changed.

Using Moment library, see their website -> https://momentjs.com/timezone/docs/#/using-timezones/converting-to-zone/

i notice they also user their own library in their website, so you can have a try using the browser console before installing it

moment().tz(String);

The moment#tz mutator will change the time zone and update the offset.

moment("2013-11-18").tz("America/Toronto").format('Z'); // -05:00
moment("2013-11-18").tz("Europe/Berlin").format('Z');   // +01:00

This information is used consistently in other operations, like calculating the start of the day.

var m = moment.tz("2013-11-18 11:55", "America/Toronto");
m.format();                     // 2013-11-18T11:55:00-05:00
m.startOf("day").format();      // 2013-11-18T00:00:00-05:00
m.tz("Europe/Berlin").format(); // 2013-11-18T06:00:00+01:00
m.startOf("day").format();      // 2013-11-18T00:00:00+01:00

Without an argument, moment#tz returns:

    the time zone name assigned to the moment instance or
    undefined if a time zone has not been set.

var m = moment.tz("2013-11-18 11:55", "America/Toronto");
m.tz();  // America/Toronto
var m = moment.tz("2013-11-18 11:55");
m.tz() === undefined;  // true

You are running the Command Prompt as an admin. You have only defined PYTHON for your user. You need to define it in the bottom "System variables" section.

Also, you should only point the variable to the folder, not directly to the executable.

divToUpdate.innerHTML =     "";   

I agree with the above comments about overriding toString() on your own classes (and about automating that process as much as possible).

For classes you didn't define, you could write a ToStringHelper class with an overloaded method for each library class you want to have handled to your own tastes:

public class ToStringHelper {
    //... instance configuration here (e.g. punctuation, etc.)
    public toString(List m) {
        // presentation of List content to your liking
    }
    public toString(Map m) {
        // presentation of Map content to your liking
    }
    public toString(Set m) {
        // presentation of Set content to your liking
    }
    //... etc.
}

EDIT: Responding to the comment by xukxpvfzflbbld, here's a possible implementation for the cases mentioned previously.

package com.so.demos;

import java.util.List;
import java.util.Map;
import java.util.Set;

public class ToStringHelper {

    private String separator;
    private String arrow;

    public ToStringHelper(String separator, String arrow) {
        this.separator = separator;
        this.arrow = arrow;
    }

   public String toString(List<?> l) {
        StringBuilder sb = new StringBuilder("(");
        String sep = "";
        for (Object object : l) {
            sb.append(sep).append(object.toString());
            sep = separator;
        }
        return sb.append(")").toString();
    }

    public String toString(Map<?,?> m) {
        StringBuilder sb = new StringBuilder("[");
        String sep = "";
        for (Object object : m.keySet()) {
            sb.append(sep)
              .append(object.toString())
              .append(arrow)
              .append(m.get(object).toString());
            sep = separator;
        }
        return sb.append("]").toString();
    }

    public String toString(Set<?> s) {
        StringBuilder sb = new StringBuilder("{");
        String sep = "";
        for (Object object : s) {
            sb.append(sep).append(object.toString());
            sep = separator;
        }
        return sb.append("}").toString();
    }

}

This isn't a full-blown implementation, but just a starter.

I had similar issue. I resolved it with just CSS.

Basically Object-fit: cover was not working in IE and it was taking 100% width and 100% height and aspect ratio was distorted. In other words image zooming effect wasn't there which I was seeing in chrome.

The approach I took was to position the image inside the container with absolute and then place it right at the centre using the combination:

position: absolute;
top: 50%;
left: 50%;
transform: translate(-50%, -50%);

Once it is in the centre, I give to the image,

// For vertical blocks (i.e., where height is greater than width)
height: 100%;
width: auto;

// For Horizontal blocks (i.e., where width is greater than height)
height: auto;
width: 100%;

This makes the image get the effect of Object-fit:cover.

Here is a demonstration of the above logic.

https://jsfiddle.net/furqan_694/s3xLe1gp/

This logic works in all browsers.

On a responsive site for mobiles the whole thing has to be positioned absolute on a relative div. And fixed height. Media Query set for relevance.

@media only screen and (max-width: 480px){_x000D_
  .scroll-wrapper{_x000D_
    position:absolute;_x000D_
    overflow-x:scroll;_x000D_
  }

Quick sort is typically faster than merge sort when the data is stored in memory. However, when the data set is huge and is stored on external devices such as a hard drive, merge sort is the clear winner in terms of speed. It minimizes the expensive reads of the external drive and also lends itself well to parallel computing.

Starting from ASP.NET Core 3.0, it is much simpler to access the environment variable from both ConfigureServices and Configure.

Simply inject IWebHostEnvironment into the Startup constructor itself. Like so...

public class Startup
{
    public Startup(IConfiguration configuration, IWebHostEnvironment env)
    {
        Configuration = configuration;
        _env = env;
    }

    public IConfiguration Configuration { get; }
    private readonly IWebHostEnvironment _env;

    public void ConfigureServices(IServiceCollection services)
    {
        if (_env.IsDevelopment())
        {
            //development
        }
    }

    public void Configure(IApplicationBuilder app)
    {
        if (_env.IsDevelopment())
        {
            //development
        }
    }
}

Reference: https://docs.microsoft.com/en-us/aspnet/core/fundamentals/environments?view=aspnetcore-3.0#inject-iwebhostenvironment-into-the-startup-class

Try with subprocess

CurlUrl="curl 'https://www.example.com/' -H 'Connection: keep-alive' -H 'Cache- 
          Control: max-age=0' -H 'Origin: https://www.example.com' -H 'Accept-Encoding: 
          gzip, deflate, br' -H 'Cookie: SESSID=ABCDEF' --data-binary 'Pathfinder' -- 
          compressed"

Use getstatusoutput to store the results

status, output = subprocess.getstatusoutput(CurlUrl)

data$anim <- sapply(0, paste0,data$anim)

POD_HOST=$(kubectl get pod $POD_NAME --template={{.status.podIP}})

This command will return you an IP

Do the following thing if you want to use json as a http request and response. So we need to make changes in [context].xml

<!-- Configure to plugin JSON as request and response in method handler -->
<beans:bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter">
    <beans:property name="messageConverters">
        <beans:list>
            <beans:ref bean="jsonMessageConverter"/>
        </beans:list>
    </beans:property>
</beans:bean>
<!-- Configure bean to convert JSON to POJO and vice versa -->
<beans:bean id="jsonMessageConverter" class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
</beans:bean>   

MappingJackson2HttpMessageConverter to the RequestMappingHandlerAdapter messageConverters so that Jackson API kicks in and converts JSON to Java Beans and vice versa. By having this configuration, we will be using JSON in request body and we will receive JSON data in the response.

I am also providing small code snippet for controller part:

    @RequestMapping(value = EmpRestURIConstants.DUMMY_EMP, method = RequestMethod.GET)

    public @ResponseBody Employee getDummyEmployee() {
    logger.info("Start getDummyEmployee");
    Employee emp = new Employee();
    emp.setId(9999);
    emp.setName("Dummy");
    emp.setCreatedDate(new Date());
    empData.put(9999, emp);
    return emp;
}

So in above code emp object will directly convert into json as a response. same will happen for post also.

In my case, it was because of exception inside the constructor of my injected dependency (in your example - inside DashboardRepository constructor). The exception was caught somewhere inside MVC infrastructure. I found this after I added logs in relevant places.

If you don't need the seeding capability just use Math.random() and build helper functions around it (eg. randRange(start, end)).

I'm not sure what RNG you're using, but it's best to know and document it so you're aware of its characteristics and limitations.

Like Starkii said, Mersenne Twister is a good PRNG, but it isn't easy to implement. If you want to do it yourself try implementing a LCG - it's very easy, has decent randomness qualities (not as good as Mersenne Twister), and you can use some of the popular constants.

EDIT: consider the great options at this answer for short seedable RNG implementations, including an LCG option.

function RNG(seed) {_x000D_
  // LCG using GCC's constants_x000D_
  this.m = 0x80000000; // 2**31;_x000D_
  this.a = 1103515245;_x000D_
  this.c = 12345;_x000D_
_x000D_
  this.state = seed ? seed : Math.floor(Math.random() * (this.m - 1));_x000D_
}_x000D_
RNG.prototype.nextInt = function() {_x000D_
  this.state = (this.a * this.state + this.c) % this.m;_x000D_
  return this.state;_x000D_
}_x000D_
RNG.prototype.nextFloat = function() {_x000D_
  // returns in range [0,1]_x000D_
  return this.nextInt() / (this.m - 1);_x000D_
}_x000D_
RNG.prototype.nextRange = function(start, end) {_x000D_
  // returns in range [start, end): including start, excluding end_x000D_
  // can't modulu nextInt because of weak randomness in lower bits_x000D_
  var rangeSize = end - start;_x000D_
  var randomUnder1 = this.nextInt() / this.m;_x000D_
  return start + Math.floor(randomUnder1 * rangeSize);_x000D_
}_x000D_
RNG.prototype.choice = function(array) {_x000D_
  return array[this.nextRange(0, array.length)];_x000D_
}_x000D_
_x000D_
var rng = new RNG(20);_x000D_
for (var i = 0; i < 10; i++)_x000D_
  console.log(rng.nextRange(10, 50));_x000D_
_x000D_
var digits = ['0', '1', '2', '3', '4', '5', '6', '7', '8', '9'];_x000D_
for (var i = 0; i < 10; i++)_x000D_
  console.log(rng.choice(digits));

The FASTEST way, to see all parents, and IN ORDER, just use the built in __mro__

i.e. repr(YOUR_CLASS.__mro__)

>>>
>>>
>>> import getpass
>>> getpass.GetPassWarning.__mro__

outputs, IN ORDER

(<class 'getpass.GetPassWarning'>, <type 'exceptions.UserWarning'>,
<type 'exceptions.Warning'>, <type 'exceptions.Exception'>, 
<type 'exceptions.BaseException'>, <type 'object'>)
>>>

There you have it. The "best" answer right now, has 182 votes (as I am typing this) but this is SO much simpler than some convoluted for loop, looking into bases one class at a time, not to mention when a class extends TWO or more parent classes. Importing and using inspect just clouds the scope unnecessarily. It honestly is a shame people don't know to just use the built-ins

I Hope this Helps!

For small times, less than an hour, I prefer:

long millis = ...

System.out.printf("%1$TM:%1$TS", millis);
// or
String str = String.format("%1$TM:%1$TS", millis);

for longer intervalls:

private static final long HOUR = TimeUnit.HOURS.toMillis(1);
...
if (millis < HOUR) {
    System.out.printf("%1$TM:%1$TS%n", millis);
} else {
    System.out.printf("%d:%2$TM:%2$TS%n", millis / HOUR, millis % HOUR);
}

I suspect you've got the same problem at least twice.

Here:

namespace TimeTest
{
    class TimeTest
    {
}

... you're declaring a type with the same name as the namespace it's in. Don't do that.

Now you apparently have the same problem with Time2. I suspect if you add:

using Time2;

to your list of using directives, your code will compile. But please, please, please fix the bigger problem: the problematic choice of names. (Follow the link above to find out more details of why it's a bad idea.)

(Additionally, unless you're really interested in writing time-based types, I'd advise you not to do so... and I say that as someone who does do exactly that. Use the built-in capabilities, or a third party library such as, um, mine. Working with dates and times correctly is surprisingly hairy. :)

A Python 2+3 compatible solution is:

import sys

if sys.version_info[0] >= 3:
    from urllib.request import urlretrieve
else:
    # Not Python 3 - today, it is most likely to be Python 2
    # But note that this might need an update when Python 4
    # might be around one day
    from urllib import urlretrieve

# Get file from URL like this:
urlretrieve("http://www-scf.usc.edu/~chiso/oldspice/m-b1-hello.mp3")

I suggest the following:

import ast

def is_int(s):
    return isinstance(ast.literal_eval(s), int)

From the docs:

Safely evaluate an expression node or a string containing a Python literal or container display. The string or node provided may only consist of the following Python literal structures: strings, bytes, numbers, tuples, lists, dicts, sets, booleans, and None.

I should note that this will raise a ValueError exception when called against anything that does not constitute a Python literal. Since the question asked for a solution without try/except, I have a Kobayashi-Maru type solution for that:

from ast import literal_eval
from contextlib import suppress

def is_int(s):
    with suppress(ValueError):
        return isinstance(literal_eval(s), int)
    return False

¯\_(?)_/¯

For posterity you might want to use regular expressions as an alternative. Pretty good browser support as well (ref. https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/match#Browser_compatibility)

Try this

if (foo.toString().match(/^(1|3|12)$/)) {
    document.write('Regex me IN<br>');
} else {
    document.write('Regex me OUT<br>');
}

If you don't declare a function and it only appears after being called, it is automatically assumed to be int, so in your case, you didn't declare

void my_print (char *);
void my_print2 (char *);

before you call it in main, so the compiler assume there are functions which their prototypes are int my_print2 (char *); and int my_print2 (char *); and you can't have two functions with the same prototype except of the return type, so you get the error of conflicting types.

As Brian suggested, declare those two methods before main.

It is indeed based on versionCode and not on versionName. However, I noticed that changing the versionCode in AndroidManifest.xml wasn't enough with Android Studio - Gradle build system. I needed to change it in the build.gradle.

select *,
case when column1 < columnl2 And column1 < column3 then column1
when columnl2 < column1 And columnl2 < column3 then columnl2
else column3
end As minValue
from   tbl_example

...
WHERE ...
      AND (@Location is null OR (Location like '%' + @Location + '%'))
      AND (@Date is null OR (Date = @Date))

This way it is more obvious the parameter is not used when null.

The best way is to use the ng-options directive on the select element.

Controller

function Ctrl($scope) {
  // sort options
  $scope.products = [{
    value: 'prod_1',
    label: 'Product 1'
  }, {
    value: 'prod_2',
    label: 'Product 2'
  }];   
}

HTML

<select ng-model="selected_product" 
        ng-options="product as product.label for product in products">           
</select>

This will bind the selected product object to the ng-model property - selected_product. After that you can use this:

<p>Ordered by: {{selected_product.label}}</p>

Access modifiers

From docs.microsoft.com:

public

The type or member can be accessed by any other code in the same assembly or another assembly that references it.

private

The type or member can only be accessed by code in the same class or struct.

protected

The type or member can only be accessed by code in the same class or struct, or in a derived class.

private protected (added in C# 7.2)

The type or member can only be accessed by code in the same class or struct, or in a derived class from the same assembly, but not from another assembly.

internal

The type or member can be accessed by any code in the same assembly, but not from another assembly.

protected internal

The type or member can be accessed by any code in the same assembly, or by any derived class in another assembly.

When no access modifier is set, a default access modifier is used. So there is always some form of access modifier even if it's not set.

static modifier

The static modifier on a class means that the class cannot be instantiated, and that all of its members are static. A static member has one version regardless of how many instances of its enclosing type are created.

A static class is basically the same as a non-static class, but there is one difference: a static class cannot be externally instantiated. In other words, you cannot use the new keyword to create a variable of the class type. Because there is no instance variable, you access the members of a static class by using the class name itself.

However, there is a such thing as a static constructor. Any class can have one of these, including static classes. They cannot be called directly & cannot have parameters (other than any type parameters on the class itself). A static constructor is called automatically to initialize the class before the first instance is created or any static members are referenced. Looks like this:

static class Foo()
{
    static Foo()
    {
        Bar = "fubar";
    }
    
    public static string Bar { get; set; }
}

Static classes are often used as services, you can use them like so:

MyStaticClass.ServiceMethod(...);

However trivial this might be, check your Java installation. For me, rt.jar was missing.

I found this after fiddling for half a day with Eclipse settings and getting nowhere. Desperate, I finally decided to try compiling the project from the command line. I wasn't expecting to see anything wrong since I thought it's an Eclipse issue but to my astonishment I saw this:

Error occurred during initialization of VM
java/lang/NoClassDefFoundError: java/lang/Object

I don't know what happened to my Java installation and where did rt.jar go. Anyway this comes as a reminder to go through the fail checklist and tick all the boxes no matter how unbelievable they are. It would have saved me a lot of time.

You could use this plugin (put it in a js file and use it via script-tag)

http://plugins.jquery.com/project/color

And then use something like this:

jQuery.fn.flash = function( color, duration )
{

    var current = this.css( 'color' );

    this.animate( { color: 'rgb(' + color + ')' }, duration / 2 );
    this.animate( { color: current }, duration / 2 );

}

This adds a 'flash' method to all jQuery objects:

$( '#importantElement' ).flash( '255,0,0', 1000 );

As per DOC:

if-else statements don't work inside JSX. This is because JSX is just syntactic sugar for function calls and object construction.

Basic Rule:

JSX is fundamentally syntactic sugar. After compilation, JSX expressions become regular JavaScript function calls and evaluate to JavaScript objects. We can embed any JavaScript expression in JSX by wrapping it in curly braces.

But only expressions not statements, means directly we can not put any statement (if-else/switch/for) inside JSX.

If you want to render the element conditionally then use ternary operator, like this:

render() {
    return (   
        <View style={styles.container}>
            {this.state.value == 'news'? <Text>data</Text>: null }
        </View>
    )
}

Another option is, call a function from jsx and put all the if-else logic inside that, like this:

renderElement(){
   if(this.state.value == 'news')
      return <Text>data</Text>;
   return null;
}

render() {
    return (   
        <View style={styles.container}>
            { this.renderElement() }
        </View>

}

I solved this by updating SDK Tools and Platform-tools in the Android SDK Manager to newest version.

Create Parcelable class without plugin in Android Studio

implements Parcelable in your class and then put cursor on "implements Parcelable" and hit Alt+Enter and select Add Parcelable implementation (see image). that's it.

Use LOWER function to convert the strings to lower case before comparing.

Try this:

SELECT id 
  FROM groups
 WHERE LOWER(name)=LOWER('Administrator')

'.'.join() or ".".join().. So any string instance has the method join()

I'm afraid I don't think there's a shortcut to do this - if only someone would write a linq wrapper for VB6!

You could write a function that does it by looping through the array and checking each entry - I don't think you'll get cleaner than that.

There's an example article that provides some details here: http://www.vb6.us/tutorials/searching-arrays-visual-basic-6

I'd stick to ActionChains for this.

Here's a function which opens a new tab and switches to that tab:

import time
from selenium.webdriver.common.action_chains import ActionChains

def open_in_new_tab(driver, element, switch_to_new_tab=True):
    base_handle = driver.current_window_handle
    # Do some actions
    ActionChains(driver) \
        .move_to_element(element) \
        .key_down(Keys.COMMAND) \
        .click() \
        .key_up(Keys.COMMAND) \
        .perform()
    
    # Should you switch to the new tab?
    if switch_to_new_tab:
        new_handle = [x for x in driver.window_handles if x!=base_handle]
        assert len new_handle == 1 # assume you are only opening one tab at a time
        
        # Switch to the new window
        driver.switch_to.window(new_handle[0])

        # I like to wait after switching to a new tab for the content to load
        # Do that either with time.sleep() or with WebDriverWait until a basic
        # element of the page appears (such as "body") -- reference for this is 
        # provided below
        time.sleep(0.5)        

        # NOTE: if you choose to switch to the window/tab, be sure to close
        # the newly opened window/tab after using it and that you switch back
        # to the original "base_handle" --> otherwise, you'll experience many
        # errors and a painful debugging experience...

Here's how you would apply that function:

# Remember your starting handle
base_handle = driver.current_window_handle

# Say we have a list of elements and each is a link:
links = driver.find_elements_by_css_selector('a[href]')

# Loop through the links and open each one in a new tab
for link in links:
    open_in_new_tab(driver, link, True)
    
    # Do something on this new page
    print(driver.current_url)
    
    # Once you're finished, close this tab and switch back to the original one
    driver.close()
    driver.switch_to.window(base_handle)
    
    # You're ready to continue to the next item in your loop

Here's how you could wait until the page is loaded.

Setting alpha property of a view affects its subviews. If you want just transparent background set view's backgroundColor proprty to a color that has alpha component smaller than 1.

view.backgroundColor = UIColor.white.withAlphaComponent(0.5)

Shift-tab does that in Flex Builder (Based on Eclipse) - SO it hopefully should work in regular eclipse :)

but select-String doesn't seem to have this option.

Correct. PowerShell is not a clone of *nix shells' toolset.

However it is not hard to build something like it yourself:

$regexes = Get-Content RegexFile.txt | 
           Foreach-Object { new-object System.Text.RegularExpressions.Regex $_ }

$fileList | Get-Content | Where-Object {
  foreach ($r in $regexes) {
    if ($r.IsMatch($_)) {
      $true
      break
    }
  }
  $false
}

Example I have a class Test:

Then. Go to config to run class Test:

Step 1: Add Application

Step 2:

You can input arguments in the Program Arguments textbox.

This would select 4 in your case

SELECT ID FROM TableA WHERE ID NOT IN (SELECT ID FROM TableB)

This would delete them

DELETE FROM TableA WHERE ID NOT IN (SELECT ID FROM TableB)

Maybe it's better to use a String representation than an integer, because the String is still valid if values are added to the enum. You can use the enum's name() method to convert the enum value to a String an the enum's valueOf() method to create an enum representation from the String again. The following example shows how to convert the enum value to String and back (ValueType is an enum):

ValueType expected = ValueType.FLOAT;
String value = expected.name();

System.out.println("Name value: " + value);

ValueType actual = ValueType.valueOf(value);

if(expected.equals(actual)) System.out.println("Values are equal");

Here's how I download an ad banner. It's best to do it in the background if you're downloading a large image or a bunch of images.

- (void)viewDidLoad {
    [super viewDidLoad];

    [self performSelectorInBackground:@selector(loadImageIntoMemory) withObject:nil];

}
- (void)loadImageIntoMemory {
    NSString *temp_Image_String = [[NSString alloc] initWithFormat:@"http://yourwebsite.com/MyImageName.jpg"];
    NSURL *url_For_Ad_Image = [[NSURL alloc] initWithString:temp_Image_String];
    NSData *data_For_Ad_Image = [[NSData alloc] initWithContentsOfURL:url_For_Ad_Image];
    UIImage *temp_Ad_Image = [[UIImage alloc] initWithData:data_For_Ad_Image];
    [self saveImage:temp_Ad_Image];
    UIImageView *imageViewForAdImages = [[UIImageView alloc] init];
    imageViewForAdImages.frame = CGRectMake(0, 0, 320, 50);
    imageViewForAdImages.image = [self loadImage];
    [self.view addSubview:imageViewForAdImages];
}
- (void)saveImage: (UIImage*)image {
    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *documentsDirectory = [paths objectAtIndex:0];
    NSString* path = [documentsDirectory stringByAppendingPathComponent: @"MyImageName.jpg" ];
    NSData* data = UIImagePNGRepresentation(image);
    [data writeToFile:path atomically:YES];
}
- (UIImage*)loadImage {
    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *documentsDirectory = [paths objectAtIndex:0];
    NSString* path = [documentsDirectory stringByAppendingPathComponent:@"MyImageName.jpg" ];
    UIImage* image = [UIImage imageWithContentsOfFile:path];
    return image;
}

You also can use in this form:

<a href="@Url.Action("Information", "Admin", null)"> Admin</a>

Create a mutex that the running thread and the calling thread both have access to. When the running thread starts it locks the mutex, and when it ends it unlocks the mutex. To check if the thread is still running, the calling thread calls mutex.try_lock(). The return value of that is the status of the thread. (Just make sure to unlock the mutex if the try_lock worked)

One small problem with this, mutex.try_lock() will return false between the time the thread is created, and when it locks the mutex, but this can be avoided using a slightly more complex method.

Tested this on a CentOS VMWare image that I keep around for this sort of thing. Note that you probably want to avoid putting passwords as command-line arguments, because anybody on the entire machine can read them out of 'ps -ef'.

That said, this will work:

user="$1"
password="$2"
adduser $user
echo $password | passwd --stdin $user

If you want to use jQuery's validate you can by creating this method:

$.validator.addMethod('filesize', function(value, element, param) {
    // param = size (en bytes) 
    // element = element to validate (<input>)
    // value = value of the element (file name)
    return this.optional(element) || (element.files[0].size <= param) 
});

You would use it:

$('#formid').validate({
    rules: { inputimage: { required: true, accept: "png|jpe?g|gif", filesize: 1048576  }},
    messages: { inputimage: "File must be JPG, GIF or PNG, less than 1MB" }
});

In linux,

find project_directory_name_here -type d -exec chmod 755 {} \;
find project_directory_name_here -type f -exec chmod 644 {} \;

It will replace all files and folder permission of project_directory_name_here and its inside stuff.

What you're looking for is

[ConditionalAttribute("DEBUG")]

attribute.

If you for instance write a method like :

[ConditionalAttribute("DEBUG")]
public static void MyLovelyDebugInfoMethod(string message)
{
    Console.WriteLine("This message was brought to you by your debugger : ");
    Console.WriteLine(message);
}

any call you make to this method inside your own code will only be executed in debug mode. If you build your project in release mode, even call to the "MyLovelyDebugInfoMethod" will be ignored and dumped out of your binary.

Oh and one more thing if you're trying to determine whether or not your code is currently being debugged at the execution moment, it is also possible to check if the current process is hooked by a JIT. But this is all together another case. Post a comment if this is what you2re trying to do.

OPTION 1: if you want to make a common utility function then you can use this

export function getCurrentDate(separator=''){

let newDate = new Date()
let date = newDate.getDate();
let month = newDate.getMonth() + 1;
let year = newDate.getFullYear();

return `${year}${separator}${month<10?`0${month}`:`${month}`}${separator}${date}`
}

and use it by just importing it as

import {getCurrentDate} from './utils'
console.log(getCurrentDate())

OPTION 2: or define and use in a class directly

getCurrentDate(separator=''){

let newDate = new Date()
let date = newDate.getDate();
let month = newDate.getMonth() + 1;
let year = newDate.getFullYear();

return `${year}${separator}${month<10?`0${month}`:`${month}`}${separator}${date}`
}

Other answers rightly point out that there is no need to use jQuery in order to navigate to another URL; that's why there's no jQuery function which does so!

If you're asking how to click a link via jQuery then assuming you have markup which looks like:

<a id="my-link" href="/relative/path.html">Click Me!</a>

You could click() it by executing:

$('#my-link').click();

localStorage.clear();

should work.

Based on the instructions at the link below, do the following.

In VBA insert a new module and paste in this code:

Public Function UserName()
    UserName = Environ$("UserName")
End Function

Call the function using the formula:

=Username()

Based on instructions at:

https://support.office.com/en-us/article/Create-Custom-Functions-in-Excel-2007-2f06c10b-3622-40d6-a1b2-b6748ae8231f

It's due to the echo statements. You could switch your echos to prints and return with an echo. Below works

#!/bin/bash

set -x
echo "enter: "
read input

function password_formula
{
        length=${#input}
        last_two=${input:length-2:length}
        first=`echo $last_two| sed -e 's/\(.\)/\1 /g'|awk '{print $2}'`
        second=`echo $last_two| sed -e 's/\(.\)/\1 /g'|awk '{print $1}'`
        let sum=$first+$second
        sum_len=${#sum}
        print $second
        print $sum

        if [ $sum -gt 9 ]
        then
           sum=${sum:1}
        fi

        value=$second$sum$first
        echo $value
}
result=$(password_formula)
echo $result

Their are two methods you can use to pass an integer. One is as shown below.

A.class

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

B.class

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

The other method converts the integer to a string and uses the following code.

A.class

Intent intent = new Intent(A.this, B.class);
Bundle extras = new Bundle();
extras.putString("StringVariableName", intValue + "");
intent.putExtras(extras);
startActivity(intent);

The code above will pass your integer value as a string to class B. On class B, get the string value and convert again as an integer as shown below.

B.class

   Bundle extras = getIntent().getExtras();
   String stringVariableName = extras.getString("StringVariableName");
   int intVariableName = Integer.parseInt(stringVariableName);

The advantage to a single CSS file is transfer efficiency. Each HTTP request means a HTTP header response for each file requested, and that takes bandwidth.

I serve my CSS as a PHP file with the "text/css" mime type in the HTTP header. This way I can have multiple CSS files on the server side and use PHP includes to push them into a single file when requested by the user. Every modern browser receives the .php file with the CSS code and processes it as a .css file.

In my opinion you should delete this AVD and create new one for API-7. It will work fine if not please let me know I'll send you some more solution.

Regards,

In case you came here looking for a way to modify logging of any (possibly deeply nested) module, use logging.Logger.manager.loggerDict to get a dictionary of all of the logger objects. The returned names can then be used as the argument to logging.getLogger:

import requests
import logging
for key in logging.Logger.manager.loggerDict:
    print(key)
# requests.packages.urllib3.connectionpool
# requests.packages.urllib3.util
# requests.packages
# requests.packages.urllib3
# requests.packages.urllib3.util.retry
# PYREADLINE
# requests
# requests.packages.urllib3.poolmanager

logging.getLogger('requests').setLevel(logging.CRITICAL)
# Could also use the dictionary directly:
# logging.Logger.manager.loggerDict['requests'].setLevel(logging.CRITICAL)

Per user136036 in a comment, be aware that this method only shows you the loggers that exist at the time you run the above snippet. If, for example, a module creates a new logger when you instantiate a class, then you must put this snippet after creating the class in order to print its name.

The public keyword is used only when declaring a class method.

Since you're declaring a simple function and not a class you need to remove public from your code.

Yes, but in what file is pyth_test's definition declared in? Is it also located before it's called?

Edit:

To put it into perspective, create a file called test.py with the following contents:

def pyth_test (x1, x2):
    print x1 + x2

pyth_test(1,2)

Now run the following command:

python test.py

You should see the output you desire. Now if you are in an interactive session, it should go like this:

>>> def pyth_test (x1, x2):
...     print x1 + x2
... 
>>> pyth_test(1,2)
3
>>> 

I hope this explains how the declaration works.

To give you an idea of how the layout works, we'll create a few files. Create a new empty folder to keep things clean with the following:

myfunction.py

def pyth_test (x1, x2):
    print x1 + x2 

program.py

#!/usr/bin/python

# Our function is pulled in here
from myfunction import pyth_test

pyth_test(1,2)

Now if you run:

python program.py

It will print out 3. Now to explain what went wrong, let's modify our program this way:

# Python: Huh? where's pyth_test?
# You say it's down there, but I haven't gotten there yet!
pyth_test(1,2)

# Our function is pulled in here
from myfunction import pyth_test

Now let's see what happens:

$ python program.py 
Traceback (most recent call last):
  File "program.py", line 3, in <module>
    pyth_test(1,2)
NameError: name 'pyth_test' is not defined

As noted, python cannot find the module for the reasons outlined above. For that reason, you should keep your declarations at top.

Now then, if we run the interactive python session:

>>> from myfunction import pyth_test
>>> pyth_test(1,2)
3

The same process applies. Now, package importing isn't all that simple, so I recommend you look into how modules work with Python. I hope this helps and good luck with your learnings!

If you use "Git for Windows"

>cd c:\Program Files\Git\etc\ssh\

add to ssh_config following:

AddKeysToAgent yes
IdentityFile ~/.ssh/id_rsa
IdentityFile ~/.ssh/id_rsa_test

ps. you need ssh version >= 7.2 (date of release 2016-02-28)

On Ubuntu, I had to delete /tmp/pip-build-root.

You can use if(addr && (addr = $.trim(addr)))

This has the advantage of actually removing any outer whitespace from addr instead of just ignoring it when performing the check.

Reference: http://api.jquery.com/jQuery.trim/

import random
import urllib.request

def download_image(url):
    name = random.randrange(1,100)
    fullname = str(name)+".jpg"
    urllib.request.urlretrieve(url,fullname)     
download_image("http://site.meishij.net/r/58/25/3568808/a3568808_142682562777944.jpg")

Separate your rules with a semi colon in a single declaration:

<span style="color:blue;font-style:italic">Test</span>

I think it would be handy to use Session.Clear() rather than using Session.Abandon().

Because the values still exist in session after calling later but are removed after calling the former.

You could use

Click TextFX ? Click TextFX Tools ? Click Sort lines case insensitive (at column) Duplicates and blank lines have been removed and the data has been sorted alphabetically.

as indicated above. However, the way I did it because I need to replace the duplicates by blank lines and not just remove the lines, once sorted alphabetically:

REPLACE:
((^.*$)(\n))(?=\k<1>)

by

$3

This will convert:

Shorts

Shorts
Shorts

Shorts Two Pack
Shorts Two Pack
Signature Braces

Signature Cotton Trousers
Signature Cotton Trousers
Signature Cotton Trousers
Signature Cotton Trousers
Signature Cotton Trousers
Signature Cotton Trousers
Signature Cotton Trousers
Signature Cotton Trousers
Signature Cotton Trousers

to:

Signature Cotton Trousers

That's how I did it because I specifically needed those lines.

This works the best, in my case, I tried it all

.div_class {
    clear: left;
}

i have been working on Apachi Axis1.1 and Axis2.0 and JAX-WS but i would suggest you must JAX-WS because it allow you make wsdl in any format , i was making operation as GetInquiry() in Apache Axis2 it did not allow me to Start Operation name in Upper Case , so i find it not good , so i would suggest you must use JAX-WS

I actually had the same problem.

when I run

mvn clean package

on my maven project, I get this certificate error by the maven tool.

I followed @Andy 's Answer till the point where I downloaded the .cer file

after that the rest of the answer didn't work for me but I did the following(I am running on Linux Debian machine)

first of all, run:

keytool -list -keystore "Java path+"/jre/lib/security/cacerts""

for example in my case it is:

keytool -list -keystore /usr/lib/jvm/jdk-8-oracle-arm32-vfp-hflt/jre/lib/security/cacerts

if it asks about the password, just hit enter.

this command is supposed to list all the ssl certificates accepted by the java. when I ran this command, in my case I got 93 certificates for example.

Now add the downloaded file .cer to the cacerts file by running the following command:

sudo keytool -importcert -file /home/hal/Public/certificate_file_downloaded.cer -keystore /usr/lib/jvm/jdk-8-oracle-arm32-vfp-hflt/jre/security/cacerts

write your sudo password then it will ask you about the keystore password

the default one is changeit

then say y that you trust this certificate.

if you run the command

keytool -list -keystore /usr/lib/jvm/jdk-8-oracle-arm32-vfp-hflt/jre/lib/security/cacerts

once again, in my case, I got 94 contents of the cacerts file

it means, it was added successfully.

In Python2, dictionary.iteritems() is more efficient than dictionary.items() so in Python3, the functionality of dictionary.iteritems() has been migrated to dictionary.items() and iteritems() is removed. So you are getting this error.

Use dict.items() in Python3 which is same as dict.iteritems() of Python2.

Simple use if you want How to execute threads alternatively :-

public class MyThread {
    public static void main(String[] args) {
        final Object lock = new Object();
        new Thread(() -> {
            try {
                synchronized (lock) {
                    for (int i = 0; i <= 5; i++) {
                        System.out.println(Thread.currentThread().getName() + ":" + "A");
                        lock.notify();
                        lock.wait();
                    }
                }
            } catch (Exception e) {}
        }, "T1").start();

        new Thread(() -> {

                        lock.wait();
                    }

Well, I think we had enough of theoretical explanations, so consider this code

public class SOP {
    public static void print(String s) {
        System.out.println(s+"\n");
    }
}

public class TestThread extends Thread {
    String name;
    TheDemo theDemo;
    public TestThread(String name,TheDemo theDemo) {
        this.theDemo = theDemo;
        this.name = name;
        start();
    }
    @Override
    public void run() {
        theDemo.test(name);
    }
}

public class TheDemo {
    public synchronized void test(String name) {
        for(int i=0;i<10;i++) {
            SOP.print(name + " :: "+i);
            try{
                Thread.sleep(500);
            } catch (Exception e) {
                SOP.print(e.getMessage());
            }
        }
    }
    public static void main(String[] args) {
        TheDemo theDemo = new TheDemo();
        new TestThread("THREAD 1",theDemo);
        new TestThread("THREAD 2",theDemo);
        new TestThread("THREAD 3",theDemo);
    }
}

Note: synchronized blocks the next thread's call to method test() as long as the previous thread's execution is not finished. Threads can access this method one at a time. Without synchronized all threads can access this method simultaneously.

When a thread calls the synchronized method 'test' of the object (here object is an instance of 'TheDemo' class) it acquires the lock of that object, any new thread cannot call ANY synchronized method of the same object as long as previous thread which had acquired the lock does not release the lock.

Similar thing happens when any static synchronized method of the class is called. The thread acquires the lock associated with the class(in this case any non static synchronized method of an instance of that class can be called by any thread because that object level lock is still available). Any other thread will not be able to call any static synchronized method of the class as long as the class level lock is not released by the thread which currently holds the lock.

@emunsing's answer is really cool for adding multiple columns, but I couldn't get it to work for me in python 2.7. Instead, I found this works:

mydf = mydf.reindex(columns = np.append( mydf.columns.values, ['newcol1','newcol2'])

You can open the project in the firebase, then you should click on the project overview, then goto project settings you will see the web API Key there.

Try:

s = filter(str.isalnum, s)

in Python3:

s = ''.join(filter(str.isalnum, s))

Edit: realized that the OP wants to replace non-chars with '*'. My answer does not fit

I had the same problem and used Glide library instead. Cache is out of the box there. https://github.com/bumptech/glide

Also something important to add here, in order to set default values for arrays and objects we must use the default function for props:

propE: {
      type: Object,
      // Object or array defaults must be returned from
      // a factory function
      default: function () {
        return { message: 'hello' }
      }
    },

If you are looking to get a comma separated string into a column with CR LF you wont be able to do that in Notepad++, assuming you didn't want to write code, you could manipulate it in Microsoft Excel.

If you copy your string to location B1:

A2 =LEFT(B1,FIND(",",B1)-1)
B2 =MID(B1,FIND(",",B1)+1,10000)

Select A2 and B2, copy the code to successive cells (by dragging):

A3 =LEFT(B2,FIND(",",B2)-1)
B3 =MID(B2,FIND(",",B2)+1,10000)

When you get #VALUE! in the last cell of column A replace it with the previous rows B value.

In the end your A column will contain the desired text. Copy and past it anywhere you wish.

For full numbers (non-floats) in Angular you can use:

if (Number.isInteger(yourVariable)) { ... }

This will work but there is still the possibility of a null record being returned. Though you may be setting the email address to a string of length zero when you insert the record, you may still want to handle the case of a NULL email address getting into the system somehow.

     $aUsers=$this->readToArray('
     SELECT `userID` 
     FROM `users` 
     WHERE `userID` 
     IN(SELECT `userID`
               FROM `users_indvSettings`
               WHERE `indvSettingID`=5 AND `optionID`='.$time.')
     AND `email` != "" AND `email` IS NOT NULL
     ');

Use String split method to remove :00.000

var formatedTime = currentTime.toString().split(':')
Text(formatedTime[0])

======= OR USE BELOW code for YYYY-MM-DD HH:MM:SS format without using library ====

var stringList =  DateTime.now().toIso8601String().split(new RegExp(r"[T\.]"));
var formatedDate = "${stringList[0]} ${stringList[1]}";

#include <bits/stdc++.h> is an implementation file for a precompiled header.

From, software engineering perspective, it is a good idea to minimize the include. If you use it actually includes a lot of files, which your program may not need, thus increase both compile-time and program size unnecessarily. [edit: as pointed out by @Swordfish in the comments that the output program size remains unaffected. But still, it's good practice to include only the libraries you actually need, unless it's some competitive competition]

But in contests, using this file is a good idea, when you want to reduce the time wasted in doing chores; especially when your rank is time-sensitive.

It works in most online judges, programming contest environments, including ACM-ICPC (Sub-Regionals, Regionals, and World Finals) and many online judges.

The disadvantages of it are that it:

• increases the compilation time.
• uses an internal non-standard header file of the GNU C++ library, and so will not compile in MSVC, XCode, and many other compilers

I had the same issue. This is my solution using angular documentation and firebase Token:

getService()  {

const accessToken=this.afAuth.auth.currentUser.getToken().then(res=>{
  const httpOptions = {
    headers: new HttpHeaders({
      'Content-Type':  'application/json',
      'Authorization': res
    })
  };
  return this.http.get('Url',httpOptions)
    .subscribe(res => console.log(res));
}); }}

try this step if you need: Xcode 11.5 1- open terminal: cd Path_project 2- cd pod clean 3- pod install

if nothing change make this step

1- open Build Phases for target -> [CP] Embed Pods FrameWork check this field

My solution to this that works for the modern YouTube embed format is as follows.

Assuming the iframe your video is playing in has id="#video", this simple bit of Javascript will do the job.

$(document).ready(function(){
  var stopVideo = function(player) {
    var vidSrc = player.prop('src');
    player.prop('src', ''); // to force it to pause
    player.prop('src', vidSrc);
  };

  // at some appropriate time later in your code
  stopVideo($('#video'));

});

I've seen proposed solutions to this issue involving use of the YouTube API, but if your site is not an https site, or your video is embedded using the modern format recommended by YouTube, or if you have the no-cookies option set, then those solutions don't work and you get the "TV set to a dead channel" effect instead of your video.

I've tested the above on every browser I could lay my hands on and it works very reliably.

@echo OFF
[your command] >> [Your log file name].txt

I used the command above in my batch file and it works. In the log file, it shows the results of my command.

If the user name that is in the connection string has access to more then one database you have to specify the database you want the connection string to connect to. If your user has only one database available then you are correct that it doesn't matter. But it is good practice to put this in your connection string.

Before teaching yourself Spring and Struts, you should probably learn Java. Output like this

org.classes.database.Employee@d9b02

is the result of the Object#toString() method which all objects inherit from the Object class, the superclass of all classes in Java.

The List sub classes implement this by iterating over all the elements and calling toString() on those. It seems, however, that you haven't implemented (overriden) the method in your Employee class.

Your JSTL here

<c:forEach items="${eList}" var="employee">
    <tr>
        <td>Employee ID: <c:out value="${employee.eid}"/></td>
        <td>Employee Pass: <c:out value="${employee.ename}"/></td>  
    </tr>
</c:forEach>

is fine except for the fact that you don't have a page, request, session, or application scoped attribute named eList.

You need to add it

<% List eList = (List)session.getAttribute("empList");
   request.setAttribute("eList", eList);
%>

Or use the attribute empList in the forEach.

<c:forEach items="${empList}" var="employee">
    <tr>
        <td>Employee ID: <c:out value="${employee.eid}"/></td>
        <td>Employee Pass: <c:out value="${employee.ename}"/></td>  
    </tr>
</c:forEach>

No you can't overload it; a static constructor is useful for initializing any static fields associated with a type (or any other per-type operations) - useful in particular for reading required configuration data into readonly fields, etc.

It is run automatically by the runtime the first time it is needed (the exact rules there are complicated (see "beforefieldinit"), and changed subtly between CLR2 and CLR4). Unless you abuse reflection, it is guaranteed to run at most once (even if two threads arrive at the same time).

In RedHat 7, we need to allow the specific port before running the Jupiter command. Say the port is 8080.

iptables -I INPUT 1 -p tcp --dport 8080 -j ACCEPT

Then we can run it normally. For instance, using:

jupyter notebook --ip 0.0.0.0 --no-browser --port=8080 --allow-root

or whatever you like.

Additionally, you will see that float values are rounded.

// e.g: given values 41.0473112,29.0077011

float(11,7) | decimal(11,7)
---------------------------
41.0473099  | 41.0473112
29.0077019  | 29.0077011

I had the same problem before and i fixed it by creating the same table in a new sheet and deleting all the name ranges associated to the table, i believe whene you're using listobjects you're not alowed to have name ranges contained within your table hope that helps thanks

Where, I solved this problem by adding the visibility attribute to the CSS code, it works on my website

Original code:

#zo2-body-wrap .introText .images:before_x000D_
{_x000D_
background:rgba(136,136,136,0.7);_x000D_
width:100%;_x000D_
height:100%;_x000D_
content:"";_x000D_
position:absolute;_x000D_
top:0;_x000D_
opacity:0;_x000D_
transition:all 0.2s ease-in-out 0s;_x000D_
}

Fixed iOS touch code:

#zo2-body-wrap .introText .images:before_x000D_
{_x000D_
background:rgba(136,136,136,0.7);_x000D_
width:100%;_x000D_
height:100%;_x000D_
content:"";_x000D_
position:absolute;_x000D_
top:0;_x000D_
visibility:hidden;_x000D_
opacity:0;_x000D_
transition:all 0.2s ease-in-out 0s;_x000D_
}

Try this one. It works for me.

SELECT * FROM eventList
WHERE DATE(date) 
  BETWEEN 
    '2013-03-26' 
  AND 
    '2013-03-27'

For a efficient solution, you can use .values() function to get a list of dict objects and then dump it to json response by using i.e. JsonResponse (remember to set safe=False).

Once you have your desired queryset object, transform it to JSON response like this:

...
data = list(queryset.values())
return JsonResponse(data, safe=False)

You can specify field names in .values() function in order to return only wanted fields (the example above will return all model fields in json objects).

In my case, I needed an additional command,

git branch --unset-upstream

to get my renamed branch to push up to origin newname.

(For ease of typing), I first git checkout oldname. Then run the following:

git branch -m newname <br/> git push origin :oldname*or*git push origin --delete oldname
git branch --unset-upstream
git push -u origin newname or git push origin newname

This extra step may only be necessary because I (tend to) set up remote tracking on my branches via git push -u origin oldname. This way, when I have oldname checked out, I subsequently only need to type git push rather than git push origin oldname.

If I do not use the command git branch --unset-upstream before git push origin newbranch, git re-creates oldbranch and pushes newbranch to origin oldbranch -- defeating my intent.

This is what I have after doing purge of all the python versions and reinstalling only 3.6.

I am totally noob at Linux, I just wanted to update Python from 2.x to 3.x so that Platformio could upgrade and now I messed up everything it seems.

Please check the following file

%SystemRoot%\system32\drivers\etc\host

The line which bind the host name with ip is probably missing a line which bind them togather

127.0.0.1  localhost

If the given line is missing. Add the line in the file

Could you also check your MySQL database's user table and tell us the host column value for the user which you are using. You should have user privilege for both the host "127.0.0.1" and "localhost" and use % as it is a wild char for generic host name.

I had this same problem.

Make sure that the prefix (android:[whatever]) is spelled correctly and written correctly. In the case of the line xmlns:android="http://schemas.android.com/apk/res/android" make sure that you have the full prefix xmlns:android and that it is spelled correctly. Same with any other prefixes - make sure they are spelled correctly and have android:[name]. This is what solved my problem.

q  = [1, 2, 3, 4, 1, 2, 5, 1, 2, 3, 4, 5]
vm = [-1, -1, -1, -1,1,2,3,1]

p = []
for v in vm:
    if v in q:
        p.append(q.index(v))
    else:
        p.append(99999)

print p
p = [q.index(v) if v in q else 99999 for v in vm]
print p

Output:

[99999, 99999, 99999, 99999, 0, 1, 2, 0]
[99999, 99999, 99999, 99999, 0, 1, 2, 0]

Instead of using append() in the list comprehension you can reference the p as direct output, and use q.index(v) and 99999 in the LC.

Not sure if this is intentional but note that q.index(v) will find just the first occurrence of v, even tho you have several in q. If you want to get the index of all v in q, consider using a enumerator and a list of already visited indexes

Something in those lines(pseudo-code):

visited = []
for i, v in enumerator(vm):
   if i not in visited:
       p.append(q.index(v))
   else:
       p.append(q.index(v,max(visited))) # this line should only check for v in q after the index of max(visited)
   visited.append(i)

This library works like a charm, easy to integrate and use. https://github.com/dm77/barcodescanner

You can use brew to start/stop pgsql. I've following short cuts in my ~/.bashrc file

alias start-pg='brew services start postgresql'
alias stop-pg='brew services stop postgresql'
alias restart-pg='brew services restart postgresql'

I was able to overcome this by using "gcc" instead of "g++" for my compiler. I know this isn't an option for most people, but thought I'd mention it as a workaround option :)

sort -u will be slightly faster, because it does not need to pipe the output between two commands

also see my question on the topic: calling uniq and sort in different orders in shell

Following closure of Python: efficient way to create a list from dict values with a given order

Retrieving the keys without building the list:

from __future__ import (absolute_import, division, print_function,
                        unicode_literals)

import collections


class DictListProxy(collections.Sequence):
    def __init__(self, klist, kdict, *args, **kwargs):
        super(DictListProxy, self).__init__(*args, **kwargs)
        self.klist = klist
        self.kdict = kdict

    def __len__(self):
        return len(self.klist)

    def __getitem__(self, key):
        return self.kdict[self.klist[key]]


myDict = {'age': 'value1', 'size': 'value2', 'weigth': 'value3'}
order_list = ['age', 'weigth', 'size']

dlp = DictListProxy(order_list, myDict)

print(','.join(dlp))
print()
print(dlp[1])

The output:

value1,value3,value2

value3

Which matches the order given by the list

You don't appear to understand what still reachable means.

Anything still reachable is not a leak. You don't need to do anything about it.

All three way you can use for newline character :

'\n'

"\n"

"""\n"""

Small addition to the help above: I got the mismatch error after adding a static libto an older VST solution using VST 2017 . VST now generates "stdfax.h" for precompiled headers containing these 2 lines:

// Turn off iterator debugging as it makes the compiler very slow on large methods in debug builds
#define _HAS_ITERATOR_DEBUGGING 0

The answer posted by @schellack is perfect for most scenarios, but I wanted Beyond Compare to simulate the '2 Way merge with a result panel' view that Visual Studio uses in its own merge window.

This config hides the middle panel (which is unused in most cases AFAIK).

Since 0.17, you have to use the explicit conversions:

pd.to_datetime, pd.to_timedelta and pd.to_numeric

(As mentioned below, no more "magic", convert_objects has been deprecated in 0.17)

df = pd.DataFrame({'x': {0: 'a', 1: 'b'}, 'y': {0: '1', 1: '2'}, 'z': {0: '2018-05-01', 1: '2018-05-02'}})

df.dtypes

x    object
y    object
z    object
dtype: object

df

   x  y           z
0  a  1  2018-05-01
1  b  2  2018-05-02

You can apply these to each column you want to convert:

df["y"] = pd.to_numeric(df["y"])
df["z"] = pd.to_datetime(df["z"])    
df

   x  y          z
0  a  1 2018-05-01
1  b  2 2018-05-02

df.dtypes

x            object
y             int64
z    datetime64[ns]
dtype: object

and confirm the dtype is updated.

OLD/DEPRECATED ANSWER for pandas 0.12 - 0.16: You can use convert_objects to infer better dtypes:

In [21]: df
Out[21]: 
   x  y
0  a  1
1  b  2

In [22]: df.dtypes
Out[22]: 
x    object
y    object
dtype: object

In [23]: df.convert_objects(convert_numeric=True)
Out[23]: 
   x  y
0  a  1
1  b  2

In [24]: df.convert_objects(convert_numeric=True).dtypes
Out[24]: 
x    object
y     int64
dtype: object

Magic! (Sad to see it deprecated.)

Hadley has a very elegant solution to do this inside data frames in his reshape package, using the function colsplit.

require(reshape)
> df <- data.frame(ID=11:13, FOO=c('a|b','b|c','x|y'))
> df
  ID FOO
1 11 a|b
2 12 b|c
3 13 x|y
> df = transform(df, FOO = colsplit(FOO, split = "\\|", names = c('a', 'b')))
> df
  ID FOO.a FOO.b
1 11     a     b
2 12     b     c
3 13     x     y

THIS IS NOT AN ANSWER TO THE ORIGINAL QUESTION, IT'S AN ANSWER TO @Teddy's QUESTION IN @Dudi's ANSWER'S COMMENTS

Here's a way to list id's in the active presentation to the immediate window (Ctrl + G) in VBA editor:

Sub ListAllShapes()

    Dim curSlide As Slide
    Dim curShape As Shape

    For Each curSlide In ActivePresentation.Slides
        Debug.Print curSlide.SlideID
        For Each curShape In curSlide.Shapes

                If curShape.TextFrame.HasText Then
                    Debug.Print curShape.Id
                End If

        Next curShape
    Next curSlide
End Sub

There are two Things you can do

use

int noOfColumns = sh.getRow(0).getPhysicalNumberOfCells();

or

int noOfColumns = sh.getRow(0).getLastCellNum();

There is a fine difference between them

1. Option 1 gives the no of columns which are actually filled with contents(If the 2nd column of 10 columns is not filled you will get 9)
2. Option 2 just gives you the index of last column. Hence done 'getLastCellNum()'

You'll find that instances of list do not provide a __hash__ --rather, that attribute of each list is actually None (try print [].__hash__). Thus, list is unhashable.

The reason your code works with list and not set is because set constructs a single set of items without duplicates, whereas a list can contain arbitrary data.

Since the only noise terminals tend to make is the bell and if you want it off everywhere, the very simplest way to do it for bash on Windows:

1. Mash backspace a bunch at the prompt
2. Right click sound icon and choose Open Volume Mixer
3. Lower volume on Console Window Host to zero

You can do this the following two ways:

1) Using loop attribute in video element (mentioned in the first answer):

2) and you can use the ended media event:

window.addEventListener('load', function(){
    var newVideo = document.getElementById('videoElementId');
    newVideo.addEventListener('ended', function() {
        this.currentTime = 0;
        this.play();
    }, false);

    newVideo.play();

});

date('Y-m-d H:i:s'). See the manual for more.

The API Guide has it all wrong (really Google?). With Maps API v2 you do not need to enable a layer to show yourself, there is a simple call to the GoogleMaps instance you created with your map.

Google Documentation

The actual documentation that Google provides gives you your answer. You just need to

If you are using Kotlin

// map is a GoogleMap object
map.isMyLocationEnabled = true

If you are using Java

// map is a GoogleMap object
map.setMyLocationEnabled(true);

and watch the magic happen.

Just make sure that you have location permission and requested it at runtime on API Level 23 (M) or above

You have strange expectations. If you gave the chain of arguments that led you to them, we might spot the flaw in them. As it is, I can only give a short primer on generics, hoping to touch on the points you might have misunderstood.

ArrayList<? extends Object> is an ArrayList whose type parameter is known to be Object or a subtype thereof. (Yes, extends in type bounds has a meaning other than direct subclass). Since only reference types can be type parameters, this is actually equivalent to ArrayList<?>.

That is, you can put an ArrayList<String> into a variable declared with ArrayList<?>. That's why a1.add(3) is a compile time error. a1's declared type permits a1 to be an ArrayList<String>, to which no Integer can be added.

Clearly, an ArrayList<?> is not very useful, as you can only insert null into it. That might be why the Java Spec forbids it:

It is a compile-time error if any of the type arguments used in a class instance creation expression are wildcard type arguments

ArrayList<ArrayList<?>> in contrast is a functional data type. You can add all kinds of ArrayLists into it, and retrieve them. And since ArrayList<?> only contains but is not a wildcard type, the above rule does not apply.

To update one column here are some syntax options:

Option 1

var ls=new int[]{2,3,4};
using (var db=new SomeDatabaseContext())
{
    var some= db.SomeTable.Where(x=>ls.Contains(x.friendid)).ToList();
    some.ForEach(a=>a.status=true);
    db.SubmitChanges();
}

Option 2

using (var db=new SomeDatabaseContext())
{
     db.SomeTable
       .Where(x=>ls.Contains(x.friendid))
       .ToList()
       .ForEach(a=>a.status=true);

     db.SubmitChanges();
}

Option 3

using (var db=new SomeDatabaseContext())
{
    foreach (var some in db.SomeTable.Where(x=>ls.Contains(x.friendid)).ToList())
    {
        some.status=true;
    }
    db.SubmitChanges();
}

Update

As requested in the comment it might make sense to show how to update multiple columns. So let's say for the purpose of this exercise that we want not just to update the status at ones. We want to update name and status where the friendid is matching. Here are some syntax options for that:

Option 1

var ls=new int[]{2,3,4};
var name="Foo";
using (var db=new SomeDatabaseContext())
{
    var some= db.SomeTable.Where(x=>ls.Contains(x.friendid)).ToList();
    some.ForEach(a=>
                    {
                        a.status=true;
                        a.name=name;
                    }
                );
    db.SubmitChanges();
}

Option 2

using (var db=new SomeDatabaseContext())
{
    db.SomeTable
        .Where(x=>ls.Contains(x.friendid))
        .ToList()
        .ForEach(a=>
                    {
                        a.status=true;
                        a.name=name;
                    }
                );
    db.SubmitChanges();
}

Option 3

using (var db=new SomeDatabaseContext())
{
    foreach (var some in db.SomeTable.Where(x=>ls.Contains(x.friendid)).ToList())
    {
        some.status=true;
        some.name=name;
    }
    db.SubmitChanges();
}

Update 2

In the answer I was using LINQ to SQL and in that case to commit to the database the usage is:

db.SubmitChanges();

But for Entity Framework to commit the changes it is:

db.SaveChanges()

Write a vba proc like:

Sub E_1()
    Call sndPlaySound32(ThisWorkbook.Path & "\e1.wav", 0)
    Range("AG" & (ActiveCell.Row)).Select 'go to column AG in the same row
End Sub

then go to developer tab, macros, select the macro, click options, then add a shortcut letter or button.

Altering a view could be accomplished by dropping the view and recreating it. Use the following to drop and recreate your view.

IF EXISTS
(SELECT NAME FROM SYS.VIEWS WHERE NAME = 'dbo.test_abc_def')
DROP VIEW dbo.test_abc_def) go

CREATE VIEW dbo.test_abc_def AS
SELECT 
    VCV.xxxx, 
    VCV.yyyy AS yyyy
    ,VCV.zzzz AS zzzz
FROM TABLE_A

You have set the upstream of that branch

(see:

• "How do you make an existing git branch track a remote branch?" and
• "Git: Why do I need to do --set-upstream-to all the time?"
  )

git branch -f --track my_local_branch origin/my_remote_branch
# OR (if my_local_branch is currently checked out):
$ git branch --set-upstream-to my_local_branch origin/my_remote_branch

(git branch -f --track won't work if the branch is checked out: use the second command git branch --set-upstream-to instead, or you would get "fatal: Cannot force update the current branch.")

That means your branch is already configured with:

branch.my_local_branch.remote origin
branch.my_local_branch.merge my_remote_branch

Git already has all the necessary information.
In that case:

# if you weren't already on my_local_branch branch:
git checkout my_local_branch 
# then:
git pull

is enough.

If you hadn't establish that upstream branch relationship when it came to push your 'my_local_branch', then a simple git push -u origin my_local_branch:my_remote_branch would have been enough to push and set the upstream branch.
After that, for the subsequent pulls/pushes, git pull or git push would, again, have been enough.

The corruption in this question is isolated to a single substring at the end of the serialized string with was probably manually replaced by someone who lazily wanted to update the image filename. This fact will be apparent in my demonstration link below using the OP's posted data -- in short, C:fakepath100.jpg does not have a length of 19, it should be 17.

Since the serialized string corruption is limited to an incorrect byte/character count number, the following will do a fine job of updating the corrupted string with the correct byte count value.

The following regex based replacement will only be effective in remedying byte counts, nothing more.

It looks like many of the earlier posts are just copy-pasting a regex pattern from someone else. There is no reason to capture the potentially corrupted byte count number if it isn't going to be used in the replacement. Also, adding the s pattern modifier is a reasonable inclusion in case a string value contains newlines/line returns.

*For those that are not aware of the treatment of multibyte characters with serializing, you must not use mb_strlen() in the custom callback because it is the byte count that is stored not the character count, see my output...

Code: (Demo with OP's data) (Demo with arbitrary sample data) (Demo with condition replacing)

$corrupted = <<<STRING
a:4:{i:0;s:3:"three";i:1;s:5:"five";i:2;s:2:"newline1
newline2";i:3;s:6:"garçon";}
STRING;

$repaired = preg_replace_callback(
        '/s:\d+:"(.*?)";/s',
        //  ^^^- matched/consumed but not captured because not used in replacement
        function ($m) {
            return "s:" . strlen($m[1]) . ":\"{$m[1]}\";";
        },
        $corrupted
    );

echo $corrupted , "\n" , $repaired;
echo "\n---\n";
var_export(unserialize($repaired));

Output:

a:4:{i:0;s:3:"three";i:1;s:5:"five";i:2;s:2:"newline1
Newline2";i:3;s:6:"garçon";}
a:4:{i:0;s:5:"three";i:1;s:4:"five";i:2;s:17:"newline1

---

  0 => 'three',
  1 => 'five',
  2 => 'newline1
Newline2',
  3 => 'garçon',
)

One leg down the rabbit hole... The above works fine even if double quotes occur in a string value, but if a string value contains "; or some other monkeywrenching sbustring, you'll need to go a little further and implement "lookarounds". My new pattern

checks that the leading s is:

• the start of the entire input string or
• preceded by ;

and checks that the "; is:

• at the end of the entire input string or
• followed by } or
• followed by a string or integer declaration s: or i:

I haven't test each and every possibility; in fact, I am relatively unfamiliar with all of the possibilities in a serialized string because I never elect to work with serialized data -- always json in modern applications. If there are additional possible leading or trailing characters, leave a comment and I'll extend the lookarounds.

Extended snippet: (Demo)

        //^^^^^^^^--------------^^^^^^^^^^^^^-- some additional validation
        function ($m) {
            return 's:' . strlen($m[1]) . ":\"{$m[1]}\";";
        },
        $corrupted_byte_counts
    );

echo "corrupted serialized array:\n$corrupted_byte_counts";
echo "\n---\n";
echo "repaired serialized array:\n$repaired";

Here is an example on how to center an object vertically with jQuery:

var div= $('#div_SomeDivYouWantToAdjust');
div.css("top", ($(window).height() - div.height())/2  + 'px');

But you could easily change that to whatever your needs are.

A big part of the REST philosophy is to exploit as many standard features of the HTTP protocol as possible when designing your API. Applying that philosophy to authentication, client and server would utilize standard HTTP authentication features in the API.

Login screens are great for human user use cases: visit a login screen, provide user/password, set a cookie, client provides that cookie in all future requests. Humans using web browsers can't be expected to provide a user id and password with each individual HTTP request.

But for a REST API, a login screen and session cookies are not strictly necessary, since each request can include credentials without impacting a human user; and if the client does not cooperate at any time, a 401 "unauthorized" response can be given. RFC 2617 describes authentication support in HTTP.

TLS (HTTPS) would also be an option, and would allow authentication of the client to the server (and vice versa) in every request by verifying the public key of the other party. Additionally this secures the channel for a bonus. Of course, a keypair exchange prior to communication is necessary to do this. (Note, this is specifically about identifying/authenticating the user with TLS. Securing the channel by using TLS / Diffie-Hellman is always a good idea, even if you don't identify the user by its public key.)

An example: suppose that an OAuth token is your complete login credentials. Once the client has the OAuth token, it could be provided as the user id in standard HTTP authentication with each request. The server could verify the token on first use and cache the result of the check with a time-to-live that gets renewed with each request. Any request requiring authentication returns 401 if not provided.

mysql_real_escape_string() or str_replace() function will help you to solve your problem.

Here you are:

let s = "hello Swift"
if let textRange = s.rangeOfString("Swift") {
    NSLog("exists")
}

You were so close! The kill -HUP method wasn't working for me either.

You were calling:

select @@global.max_connections;

All you needed was to set instead of select:

set @@global.max_connections = 400;

See:

http://www.netadmintools.com/art573.html

http://www.electrictoolbox.com/update-max-connections-mysql/

I was receiving the same error message, and my issue was that I was not in the correct directory when running the command make install. When I changed to the directory that had my makefile it worked.

So possibly you aren't in the right directory.

Try the following:

<script> 
 //Functions to open database and to create, insert data into tables

 getSelectedRow = function(val)
    {
        db.transaction(function(transaction) {
              transaction.executeSql('SELECT * FROM Employ where number = ?;',[parseInt(val)], selectedRowValues, errorHandler);

        });
    };
    selectedRowValues = function(transaction,results)
    {
         for(var i = 0; i < results.rows.length; i++)
         {
             var row = results.rows.item(i);
             alert(row['number']);
             alert(row['name']);                 
         }
    };
</script>

You don't have access to javascript variable names in SQL, you must pass the values to the Database.

in my case, only height: 100vh fix the problem with the expected behavior

Vue 2.x

For Official information:

https://vuejs.org/v2/guide/migration.html#v-el-and-v-ref-replaced

A simple Example:

On any Element you have to add an attribute ref with a unique value

<input ref="foo" type="text" >

To target that elemet use this.$refs.foo

this.$refs.foo.focus(); // it will focus the input having ref="foo"

Try this sample SQL scripts for easy understanding,

CREATE TABLE TABLE1 (REFNO VARCHAR(10))
CREATE TABLE TABLE2 (REFNO VARCHAR(10))

--TRUNCATE TABLE TABLE1
--TRUNCATE TABLE TABLE2

INSERT INTO TABLE1 SELECT 'TEST_NAME'
INSERT INTO TABLE1 SELECT 'KUMAR'
INSERT INTO TABLE1 SELECT 'SIVA'
INSERT INTO TABLE1 SELECT 'SUSHANT'

INSERT INTO TABLE2 SELECT 'KUMAR'
INSERT INTO TABLE2 SELECT 'SIVA'
INSERT INTO TABLE2 SELECT 'SUSHANT'

SELECT * FROM TABLE1
SELECT * FROM TABLE2

DELETE T1 FROM TABLE1 T1 JOIN TABLE2 T2 ON T1.REFNO = T2.REFNO

Your case is:

   DELETE pgc
     FROM guide_category pgc 
LEFT JOIN guide g
       ON g.id_guide = gc.id_guide 
    WHERE g.id_guide IS NULL

• .length is a field, containing the capacity (NOT the number of elements the array contains at the moment) of arrays.

• length() is a method used by Strings (amongst others), it returns the number of chars in the String; with Strings, capacity and number of containing elements (chars) have the same value.

• size() is a method implemented by all members of Collection (lists, sets, stacks,...). It returns the number of elements (NOT the capacity; some collections even don´t have a defined capacity) the collection contains.

Thanks to @CopsOnRoad, his solution was a big help but only works for SDK 26 and higher. My app targets 24 and higher.

To keep Android Studio from complaining you need a conditional directly around the notification. It is not smart enough to know the code is in a method conditional to VERSION_CODE.O.

@Override
public void onCreate(){
    super.onCreate();
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O)
        startMyOwnForeground();
    else
        startForeground(1, new Notification());
}

private void startMyOwnForeground(){

    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O){

        String NOTIFICATION_CHANNEL_ID = "com.example.simpleapp";
        String channelName = "My Background Service";
        NotificationChannel chan = new NotificationChannel(NOTIFICATION_CHANNEL_ID, channelName, NotificationManager.IMPORTANCE_NONE);
        chan.setLightColor(Color.BLUE);
        chan.setLockscreenVisibility(Notification.VISIBILITY_PRIVATE);
        NotificationManager manager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
        assert manager != null;
        manager.createNotificationChannel(chan);

        NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this, NOTIFICATION_CHANNEL_ID);
        Notification notification = notificationBuilder.setOngoing(true)
                .setSmallIcon(AppSpecific.SMALL_ICON)
                .setContentTitle("App is running in background")
                .setPriority(NotificationManager.IMPORTANCE_MIN)
                .setCategory(Notification.CATEGORY_SERVICE)
                .build();
        startForeground(2, notification);
    }
}

Approach: calculate keys to remove, mutate dict

Let's call keys the list/iterator of keys that you are given to remove. I'd do this:

keys_to_remove = set(keys).intersection(set(mydict.keys()))
for key in keys_to_remove:
    del mydict[key]

You calculate up front all the affected items and operate on them.

Approach: calculate keys to keep, make new dict with those keys

I prefer to create a new dictionary over mutating an existing one, so I would probably also consider this:

keys_to_keep = set(mydict.keys()) - set(keys)
new_dict = {k: v for k, v in mydict.iteritems() if k in keys_to_keep}

or:

keys_to_keep = set(mydict.keys()) - set(keys)
new_dict = {k: mydict[k] for k in keys_to_keep}

To sum it up,in object oriented programming, everything is modeled into classes and objects. Classes contain properties and methods. Public, private and protected keywords are used to specify access to these members(properties and methods) of a class from other classes or other .dlls or even other applications.

This problem can be caused by requests for certain files that don't exist. For example, requests for files in wp-content/uploads/ where the file does not exist.

If this is the situation you're seeing, you can solve the problem by going to .htaccess and changing this line:

RewriteRule ^(wp-(content|admin|includes).*) $1 [L]

to:

RewriteRule ^(wp-(content|admin|includes).*) - [L]

The underlying issue is that the rule above triggers a rewrite to the exact same url with a slash in front and because there was a rewrite, the newly rewritten request goes back through the rules again and the same rule is triggered. By changing that line's "$1" to "-", no rewrite happens and so the rewriting process does not start over again with the same URL.

It's possible that there's a difference in how apache 2.2 and 2.4 handle this situation of only-difference-is-a-slash-in-front and that's why the default rules provided by WordPress aren't working perfectly.

Use PowerMockito on top of Mockito.

Example code:

@RunWith(PowerMockRunner.class)
@PrepareForTest(DriverManager.class)
public class Mocker {

    @Test
    public void shouldVerifyParameters() throws Exception {

        //given
        PowerMockito.mockStatic(DriverManager.class);
        BDDMockito.given(DriverManager.getConnection(...)).willReturn(...);

        //when
        sut.execute(); // System Under Test (sut)

        //then
        PowerMockito.verifyStatic();
        DriverManager.getConnection(...);

    }

• Why doesn't Mockito mock static methods?

If the .c source files are converted .cpp (like as in parsec), then the extern needs to be followed by "C" as in

extern "C" void foo();

Solution that worked for me on Windows: Install both the 32-bit and 64-bit versions of the MySQL Connector/C 6.0.2. Open Command Prompt and run:

pip install mysql-python

If you have access to netstat, that can do precisely that.

In jsp you can do it like this:

<%
boolean checkboxDisabled = true; //do your logic here
String checkboxState = checkboxDisabled ? "disabled" : "";
%>
<input type="checkbox" <%=checkboxState%>>

https://github.com/IdentityModel/IdentityModel adds extensions to HttpClient to acquire tokens using different flows and the documentation is great too. It's very handy because you don't have to think how to implement it yourself. I'm not aware if any official MS implementation exists.

d stands for Declaration Files:

When a TypeScript script gets compiled there is an option to generate a declaration file (with the extension .d.ts) that functions as an interface to the components in the compiled JavaScript. In the process the compiler strips away all function and method bodies and preserves only the signatures of the types that are exported. The resulting declaration file can then be used to describe the exported virtual TypeScript types of a JavaScript library or module when a third-party developer consumes it from TypeScript.

The concept of declaration files is analogous to the concept of header file found in C/C++.

declare module arithmetics {
    add(left: number, right: number): number;
    subtract(left: number, right: number): number;
    multiply(left: number, right: number): number;
    divide(left: number, right: number): number;
}

Type declaration files can be written by hand for existing JavaScript libraries, as has been done for jQuery and Node.js.

Large collections of declaration files for popular JavaScript libraries are hosted on GitHub in DefinitelyTyped and the Typings Registry. A command-line utility called typings is provided to help search and install declaration files from the repositories.

MDN docs for parseInt
MDN docs for parseFloat

In parseInt radix is specified as ten so that we are in base 10. In nonstrict javascript a number prepended with 0 is treated as octal. This would obviously cause problems!

parseInt(num1, 10) + parseInt(num2, 10) //base10
parseFloat(num1) + parseFloat(num2)

Also see ChaosPandion's answer for a useful shortcut using a unary operator. I have set up a fiddle to show the different behaviors.

http://jsfiddle.net/EtX6G/

var ten = '10';
var zero_ten = '010';
var one = '1';
var body = document.getElementsByTagName('body')[0];

Append(parseInt(ten) + parseInt(one));
Append(parseInt(zero_ten) + parseInt(one));
Append(+ten + +one);
Append(+zero_ten + +one);

function Append(text) {
    body.appendChild(document.createTextNode(text));
    body.appendChild(document.createElement('br'));
}

You can use this function to convert comma-delimited single character strings to list-

def stringtolist(x):
    mylist=[]
    for i in range(0,len(x),2):
        mylist.append(x[i])
    return mylist

I like using Tiny Types which would wrap either a double, BigDecimal, or int as previous answers have suggested. (I would use a double unless precision problems crop up).

A Tiny Type gives you type safety so you don't confused a double money with other doubles.

for ($s=65; $s<=90; $s++) {
    //echo chr($s);
    $objPHPExcel->getActiveSheet()->getColumnDimension(chr($s))->setAutoSize(true);
}

Iterate over the Array. First initialize the maximum value to the first element of the array and then for each element optimize it if the element under consideration is greater.

Use 51Degrees.com device detection solution to detect browser name, vendor and version.

First, follow the 4-step guide to incorporate device detector in to your project. When I say incorporate I mean download archive with PHP code and database file, extract them and include 2 files. That's all there is to do to incorporate.

Once that's done you can use the following properties to get browser information:
$_51d['BrowserName'] - Gives you the name of the browser (Safari, Molto, Motorola, MStarBrowser etc).
$_51d['BrowserVendor'] - Gives you the company who created browser.
$_51d['BrowserVersion'] - Version number of the browser

Just insert or update mysql.user with value Y in each column privileges.

For passing both a function, and any arguments to the function:

from typing import Callable    

def looper(fn: Callable, n:int, *args, **kwargs):
    """
    Call a function `n` times

    Parameters
    ----------
    fn: Callable
        Function to be called.
    n: int
        Number of times to call `func`.
    *args
        Positional arguments to be passed to `func`.
    **kwargs
        Keyword arguments to be passed to `func`.

    Example
    -------
    >>> def foo(a:Union[float, int], b:Union[float, int]):
    ...    '''The function to pass'''
    ...    print(a+b)
    >>> looper(foo, 3, 2, b=4)
    6
    6
    6       
    """
    for i in range(n):
        fn(*args, **kwargs)

Depending on what you are doing, it could make sense to define a decorator, or perhaps use functools.partial.

I'm using something like this and works very well:* :-)

Note: Linux/Mac/Bash only, though probably there's a way to do that in Windows/PowerShell too.

Basing off of m59's very good answer. I found that model inputs would be blurred if they changed, so you could only change one character at a time. This is a new one for lists of objects for anyone that needs it:

EDIT Updated to handle multiple filters on one page

app.filter('partition', function() {
  var cache = {}; // holds old arrays for difference repeat scopes
  var filter = function(newArr, size, scope) {
    var i,
      oldLength = 0,
      newLength = 0,
      arr = [],
      id = scope.$id,
      currentArr = cache[id];
    if (!newArr) return;

    if (currentArr) {
      for (i = 0; i < currentArr.length; i++) {
        oldLength += currentArr[i].length;
      }
    }
    if (newArr.length == oldLength) {
      return currentArr; // so we keep the old object and prevent rebuild (it blurs inputs)
    } else {
      for (i = 0; i < newArr.length; i += size) {
        arr.push(newArr.slice(i, i + size));
      }
      cache[id] = arr;
      return arr;
    }
  };
  return filter;
}); 

And this would be the usage:

<div ng-repeat="row in items | partition:3:this">
  <span class="span4">
    {{ $index }}
  </span>
</div>

For a one-page web application where I add scrollable sections dynamically, I trigger OSX's scrollbars by programmatically scrolling one pixel down and back up:

// Plain JS:
var el = document.getElementById('scrollable-section');
el.scrollTop = 1;
el.scrollTop = 0;

// jQuery:
$('#scrollable-section').scrollTop(1).scrollTop(0);

This triggers the visual cue fading in and out.

The width of the button is defined by the button text. So if you want to define the width of the button you can use a defined width by using pixel in the css or if you want to by responsive use a percentage value.

Here is a complete example

#include <thread>
#include <iostream>

class Wrapper {
   public:
      void member1() {
          std::cout << "i am member1" << std::endl;
      }
      void member2(const char *arg1, unsigned arg2) {
          std::cout << "i am member2 and my first arg is (" << arg1 << ") and second arg is (" << arg2 << ")" << std::endl;
      }
      std::thread member1Thread() {
          return std::thread([=] { member1(); });
      }
      std::thread member2Thread(const char *arg1, unsigned arg2) {
          return std::thread([=] { member2(arg1, arg2); });
      }
};
int main(int argc, char **argv) {
   Wrapper *w = new Wrapper();
   std::thread tw1 = w->member1Thread();
   std::thread tw2 = w->member2Thread("hello", 100);
   tw1.join();
   tw2.join();
   return 0;
}

Compiling with g++ produces the following result

g++ -Wall -std=c++11 hello.cc -o hello -pthread

i am member1
i am member2 and my first arg is (hello) and second arg is (100)

It's not possible to save content to the website using only client-side scripting such as JavaScript and jQuery, but by submitting the data in an AJAX POST request you could perform the other half very easily on the server-side.

However, I would not recommend having raw content such as scripts so easily writeable to your hosting as this could easily be exploited. If you want to learn more about AJAX POST requests, you can read the jQuery API page:

http://api.jquery.com/jQuery.post/

And here are some things you ought to be aware of if you still want to save raw script files on your hosting. You have to be very careful with security if you are handling files like this!

robocopy:

Robocopy, or "Robust File Copy", is a command-line directory and/or file replication command. Robocopy functionally replaces Xcopy, with more options. It has been available as part of the Windows Resource Kit starting with Windows NT 4.0, and was first introduced as a standard feature in Windows Vista and Windows Server 2008. The command is robocopy...

Using lambdas and functional interfaces in Java 8 makes creating new loop abstractions possible. I can loop over a collection with the index and the collection size:

List<String> strings = Arrays.asList("one", "two","three","four");
forEach(strings, (x, i, n) -> System.out.println("" + (i+1) + "/"+n+": " + x));

Which outputs:

1/4: one
2/4: two
3/4: three
4/4: four

Which I implemented as:

   @FunctionalInterface
   public interface LoopWithIndexAndSizeConsumer<T> {
       void accept(T t, int i, int n);
   }
   public static <T> void forEach(Collection<T> collection,
                                  LoopWithIndexAndSizeConsumer<T> consumer) {
      int index = 0;
      for (T object : collection){
         consumer.accept(object, index++, collection.size());
      }
   }

The possibilities are endless. For example, I create an abstraction that uses a special function just for the first element:

forEachHeadTail(strings, 
                (head) -> System.out.print(head), 
                (tail) -> System.out.print(","+tail));

Which prints a comma separated list correctly:

one,two,three,four

Which I implemented as:

public static <T> void forEachHeadTail(Collection<T> collection, 
                                       Consumer<T> headFunc, 
                                       Consumer<T> tailFunc) {
   int index = 0;
   for (T object : collection){
      if (index++ == 0){
         headFunc.accept(object);
      }
      else{
         tailFunc.accept(object);
      }
   }
}

Libraries will begin to pop up to do these sorts of things, or you can roll your own.

Use an interval instead of an integer:

SELECT *
FROM table
WHERE auth_user.lastactivity > CURRENT_TIMESTAMP - INTERVAL '100 days'

Add this function inside your Auth\LoginController.php

use Illuminate\Http\Request;

And also add this

public function logout(Request $request)
{
    $this->guard()->logout();

    $request->session()->invalidate();

    return $this->loggedOut($request) ?: redirect('/login');
}

This one works for me:

modal

<div class="modal fade" id="searchKaryawan" tabindex="-1" role="dialog" aria-labelledby="SearchKaryawanLabel" aria-hidden="true"> <div class="modal-dialog">
<div class="modal-content">
  <div class="modal-header">
    <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">&times;</span></button>
    <h4 class="modal-title" id="SearchKaryawanLabel">Cari Karyawan</h4>
  </div>
  <div class="modal-body">
    <input type="hidden" name="location">
    <input name="cariNama" type="text" class="form-control" onkeyup="if (this.value.length > 3) cariNikNama();" />
    <div class="links-area" id="links-area"></div>
  </div>
  <div class="modal-footer">
  </div>
</div> </div></div>

script

<script type="text/javascript">$('body').on('hidden.bs.modal', '.modal', function () {  $(".links-area").empty() }); </script>

links-area is area where i put the data and need to clear

I also get this when using the HTTPS everywhere plugin. This plugin has a list of sites that also have https instead of http. So I assume before the actual request is made it is already being cancelled somehow.

So for example when I go to http://stackexchange.com, in Developer I first see a request with status (terminated). This request has some headers, but only the GET, User-Agent, and Accept. No response as well.

Then there is request to https://stackexchange.com with full headers etc.

So I assume it is used for requests that aren't sent.

How to determine the variable type in Python?

So if you have a variable, for example:

one = 1

You want to know its type?

There are right ways and wrong ways to do just about everything in Python. Here's the right way:

Use type

>>> type(one)
<type 'int'>

You can use the __name__ attribute to get the name of the object. (This is one of the few special attributes that you need to use the __dunder__ name to get to - there's not even a method for it in the inspect module.)

>>> type(one).__name__
'int'

Don't use __class__

In Python, names that start with underscores are semantically not a part of the public API, and it's a best practice for users to avoid using them. (Except when absolutely necessary.)

Since type gives us the class of the object, we should avoid getting this directly. :

>>> one.__class__

This is usually the first idea people have when accessing the type of an object in a method - they're already looking for attributes, so type seems weird. For example:

class Foo(object):
    def foo(self):
        self.__class__

Don't. Instead, do type(self):

class Foo(object):
    def foo(self):
        type(self)

Implementation details of ints and floats

How do I see the type of a variable whether it is unsigned 32 bit, signed 16 bit, etc.?

In Python, these specifics are implementation details. So, in general, we don't usually worry about this in Python. However, to sate your curiosity...

In Python 2, int is usually a signed integer equal to the implementation's word width (limited by the system). It's usually implemented as a long in C. When integers get bigger than this, we usually convert them to Python longs (with unlimited precision, not to be confused with C longs).

For example, in a 32 bit Python 2, we can deduce that int is a signed 32 bit integer:

>>> import sys

>>> format(sys.maxint, '032b')
'01111111111111111111111111111111'
>>> format(-sys.maxint - 1, '032b') # minimum value, see docs.
'-10000000000000000000000000000000'

In Python 3, the old int goes away, and we just use (Python's) long as int, which has unlimited precision.

We can also get some information about Python's floats, which are usually implemented as a double in C:

>>> sys.float_info
sys.floatinfo(max=1.7976931348623157e+308, max_exp=1024, max_10_exp=308, 
min=2.2250738585072014e-308, min_exp=-1021, min_10_exp=-307, dig=15, 
mant_dig=53, epsilon=2.2204460492503131e-16, radix=2, rounds=1)

Conclusion

Don't use __class__, a semantically nonpublic API, to get the type of a variable. Use type instead.

And don't worry too much about the implementation details of Python. I've not had to deal with issues around this myself. You probably won't either, and if you really do, you should know enough not to be looking to this answer for what to do.

$array = array("Jonathan","Sampson");

foreach($array as $value) {
  print $value;
}

or

$length = count($array);
for ($i = 0; $i < $length; $i++) {
  print $array[$i];
}

If you want to specifically use java ArrayList then you can do something like this:

fun initList(){
    val list: ArrayList<String> = ArrayList()
    list.add("text")
    println(list)
}

Try downloading apache-jmeter-2.6.zip from http://www.apache.org/dist/jmeter/binaries/

This contains the proper ApacheJMeter.jar that is needed to initiate.

Go to bin folder in the command prompt and try java -jar ApacheJMeter.jar if the download is correct this should open the GUI.

Edit on 23/08/2018:

• The correct answer as of current modern JMeter versions is https://stackoverflow.com/a/51973791/460802

try this one out.

<label for="user">user</label>
<input type="text" name="user" 
onfocus="if(this.value==this.defaultValue)this.value=''"    
onblur="if(this.value=='')this.value=this.defaultValue" 
value="username" maxlength="19" />

hope this helps.

You need to have DocumentFormat.OpenXML.dll in the same folder as your application - or in the 'bin' path if you are developing an ASP.NET application. However, I'm not certain that the OpenXML SDK is supported on non-Windows operating systems - you may need to look into a third-party solution.

Yes, this answer is right, the only difference is that you copy your .dll into bin folder of the project.

I like the Apache Commons IO library. Take a look at its version of ByteArrayOutputStream, which has a toString(String enc) method as well as toByteArray(). Using existing and trusted components like the Commons project lets your code be smaller and easier to extend and repurpose.

provider another solution based on git

start a new project

rails new project_name
cd project_name

initialize git

git init
git commit -m "initial commit"

create a scaffold

rails g scaffold MyScaffold
rake db:migrate

rollback the scaffold

rake db:rollback
git reset --hard
git clean -f -d

Dependency Injection

Instead of instantiating the parts itself a car asks for the parts it needs to function.

class Car
{
    private Engine engine;
    private SteeringWheel wheel;
    private Tires tires;

    public Car(Engine engine, SteeringWheel wheel, Tires tires)
    {
        this.engine = engine;
        this.wheel = wheel;
        this.tires = tires;
    }
}

Factory

Puts the pieces together to make a complete object and hides the concrete type from the caller.

static class CarFactory
{
    public ICar BuildCar()
    {
        Engine engine = new Engine();
        SteeringWheel steeringWheel = new SteeringWheel();
        Tires tires = new Tires();
        ICar car = new RaceCar(engine, steeringWheel, tires);
        return car;
    }   
}

Result

As you can see, Factories and DI complement each other.

static void Main()
{
     ICar car = CarFactory.BuildCar();
     // use car
}

Do you remember goldilocks and the three bears? Well, dependency injection is kind of like that. Here are three ways to do the same thing.

void RaceCar() // example #1
{
    ICar car = CarFactory.BuildCar();
    car.Race();
}

void RaceCar(ICarFactory carFactory) // example #2
{
    ICar car = carFactory.BuildCar();
    car.Race();
}

void RaceCar(ICar car) // example #3
{
    car.Race();
}

Example #1 - This is the worst because it completely hides the dependency. If you looked at the method as a black box you would have no idea it required a car.

Example #2 - This is a little better because now we know we need a car since we pass in a car factory. But this time we are passing too much since all the method actually needs is a car. We are passing in a factory just to build the car when the car could be built outside the method and passed in.

Example #3 - This is ideal because the method asks for exactly what it needs. Not too much or too little. I don't have to write a MockCarFactory just to create MockCars, I can pass the mock straight in. It is direct and the interface doesn't lie.

This Google Tech Talk by Misko Hevery is amazing and is the basis of what I derived my example from. http://www.youtube.com/watch?v=XcT4yYu_TTs

I personally would recommend NOT doing it... If it's responding to some sort of action and it needs to change its appearance, I would prefer raising an event and letting it sort itself out...

This kind of coupling between forms always makes me nervous. I always try to keep the UI as light and independent as possible..

I hope this helps. Perhaps you could expand on the scenario if not?

You can't directly call a function in another shell script.

You can move your function definitions into a separate file and then load them into your script using the . command, like this:

. /path/to/functions.sh

This will interpret functions.sh as if it's content were actually present in your file at this point. This is a common mechanism for implementing shared libraries of shell functions.

Try this:

@echo off
setlocal
cd /d %~dp0
Call :UnZipFile "C:\Temp\" "c:\path\to\batch.zip"
exit /b

:UnZipFile <ExtractTo> <newzipfile>
set vbs="%temp%\_.vbs"
if exist %vbs% del /f /q %vbs%
>%vbs%  echo Set fso = CreateObject("Scripting.FileSystemObject")
>>%vbs% echo If NOT fso.FolderExists(%1) Then
>>%vbs% echo fso.CreateFolder(%1)
>>%vbs% echo End If
>>%vbs% echo set objShell = CreateObject("Shell.Application")
>>%vbs% echo set FilesInZip=objShell.NameSpace(%2).items
>>%vbs% echo objShell.NameSpace(%1).CopyHere(FilesInZip)
>>%vbs% echo Set fso = Nothing
>>%vbs% echo Set objShell = Nothing
cscript //nologo %vbs%
if exist %vbs% del /f /q %vbs%

Revision

To have it perform the unzip on each zip file creating a folder for each use:

@echo off
setlocal
cd /d %~dp0
for %%a in (*.zip) do (
    Call :UnZipFile "C:\Temp\%%~na\" "c:\path\to\%%~nxa"
)
exit /b

If you don't want it to create a folder for each zip, change Call :UnZipFile "C:\Temp\%%~na\" "c:\path\to\%%~nxa" to Call :UnZipFile "C:\Temp\" "c:\path\to\%%~nxa"

According to Parsing HTML documents - The end,

1. The browser parses the HTML source and runs deferred scripts.

2. A DOMContentLoaded is dispatched at the document when all the HTML has been parsed and have run. The event bubbles to the window.

3. The browser loads resources (like images) that delay the load event.

4. A load event is dispatched at the window.

Therefore, the order of execution will be

1. DOMContentLoaded event listeners of window in the capture phase
2. DOMContentLoaded event listeners of document
3. DOMContentLoaded event listeners of window in the bubble phase
4. load event listeners (including onload event handler) of window

A bubble load event listener (including onload event handler) in document should never be invoked. Only capture load listeners might be invoked, but due to the load of a sub-resource like a stylesheet, not due to the load of the document itself.
