I found this to occur when you mix ggplot charts with plot charts in the same session. Using the 'dev.off' solution suggested by Paul solves the issue.

You can add it like this

header('Location: http://linkhere.com/'.$url_endpoint);

It is very bad style to define external interfaces in .c files. .

You should do this

a.h

    extern void doSomething (int    sig);

a.c

    void doSomething (int    sig)
    {
       ... do stuff 
    }

b.c

#include "a.h"
.....
signal(SIGNAL, doSomething); 

.

Tim Stone's solution is on the right track, but his initial rewriterule and and his cookie name in the final condition are different, and you can not write and read a cookie in the same request.

Here is the finalized working code:

RewriteEngine on
RewriteBase /
# Check if this is the noredirect query string
RewriteCond %{QUERY_STRING} (^|&)m=0(&|$)
# Set a cookie, and skip the next rule
RewriteRule ^ - [CO=mredir:0:www.website.com]

# Check if this looks like a mobile device
# (You could add another [OR] to the second one and add in what you
#  had to check, but I believe most mobile devices should send at
#  least one of these headers)
RewriteCond %{HTTP:x-wap-profile} !^$ [OR]
RewriteCond %{HTTP:Profile}       !^$ [OR]
RewriteCond %{HTTP_USER_AGENT} "acs|alav|alca|amoi|audi|aste|avan|benq|bird|blac|blaz|brew|cell|cldc|cmd-" [NC,OR]
RewriteCond %{HTTP_USER_AGENT} "dang|doco|eric|hipt|inno|ipaq|java|jigs|kddi|keji|leno|lg-c|lg-d|lg-g|lge-" [NC,OR]

Note Slipstream's response, that base64.b64encode and base64.b64decode need bytes-like object, not string.

Here is a Swift extension to UIImage that rotates the image by any arbitrary angle. Use it like this: let rotatedImage = image.rotated(byDegrees: degree). I used the Objective-C code in one of the other answers and removed a few lines that we incorrect (rotated box stuff) and turned it into an extension for UIImage.

extension UIImage {

func rotate(byDegrees degree: Double) -> UIImage {
    let radians = CGFloat(degree*M_PI)/180.0 as CGFloat
    let rotatedSize = self.size
    let scale = UIScreen.mainScreen().scale
    UIGraphicsBeginImageContextWithOptions(rotatedSize, false, scale)
    let bitmap = UIGraphicsGetCurrentContext()
    CGContextTranslateCTM(bitmap, rotatedSize.width / 2, rotatedSize.height / 2);
    CGContextRotateCTM(bitmap, radians);
    CGContextScaleCTM(bitmap, 1.0, -1.0);
    CGContextDrawImage(bitmap, CGRectMake(-self.size.width / 2, -self.size.height / 2 , self.size.width, self.size.height), self.CGImage );
    let newImage = UIGraphicsGetImageFromCurrentImageContext()

    return newImage
}
}

Switching to the use of https works. First switch to https rather than ssh keys. git remote set-url origin

It will then request for the git username and password.

None of the previous answers (to this date) gives the correct difference in days between two dates.

The one that comes closest is by thatdankent. A full answer would convert to_i and then divide:

(Time.now.to_i - 23.hours.ago.to_i) / 86400
>> 0

(Time.now.to_i - 25.hours.ago.to_i) / 86400
>> 1

(Time.now.to_i - 1.day.ago.to_i) / 86400
>> 1

In the question's specific example, one should not parse to Date if the time passed is relevant. Use Time.parse instead.

I guess compatible way:

hash=`genhash --use-ssl -s $IP -p 443 --url $URL | grep MD5 | grep -c $MD5`

but I prefer

hash="$(genhash --use-ssl -s $IP -p 443 --url $URL | grep MD5 | grep -c $MD5)"

Use CSS3 PIE, which emulates some CSS3 properties in older versions of IE.

It supports box-shadow (except for the inset keyword).

commons-lang3 from Apache contains valuable utility/convenience methods for all kinds of 'problems', including this one.

System.out.println(StringUtils.isAsciiPrintable("!@£$%^&!@£$%^"));

I would sugest to init the Class from RSC:

import Foundation
import UIKit

// Don't forget the delegate!
class ViewController: UIViewController, UITextFieldDelegate {

required init(coder aDecoder: NSCoder) {
    fatalError("init(coder:) has not been implemented")
}

@IBOutlet var myTextField : UITextField?

override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view, typically from a nib.

    self.myTextField.delegate = self;
}

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
    // Dispose of any resources that can be recreated.
}

func textFieldShouldReturn(textField: UITextField!) -> Bool {
    self.view.endEditing(true);
    return false;
}

}

Just use the sys.getsizeof function defined in the sys module.

sys.getsizeof(object[, default]):

Return the size of an object in bytes. The object can be any type of object. All built-in objects will return correct results, but this does not have to hold true for third-party extensions as it is implementation specific.

Only the memory consumption directly attributed to the object is accounted for, not the memory consumption of objects it refers to.

The default argument allows to define a value which will be returned if the object type does not provide means to retrieve the size and would cause a TypeError.

getsizeof calls the object’s __sizeof__ method and adds an additional garbage collector overhead if the object is managed by the garbage collector.

See recursive sizeof recipe for an example of using getsizeof() recursively to find the size of containers and all their contents.

Usage example, in python 3.0:

>>> import sys
>>> x = 2
>>> sys.getsizeof(x)
24
>>> sys.getsizeof(sys.getsizeof)
32
>>> sys.getsizeof('this')
38
>>> sys.getsizeof('this also')
48

If you are in python < 2.6 and don't have sys.getsizeof you can use this extensive module instead. Never used it though.

Did you try df.groupby('id').head(2)

Ouput generated:

>>> df.groupby('id').head(2)
       id  value
id             
1  0   1      1
   1   1      2 
2  3   2      1
   4   2      2
3  7   3      1
4  8   4      1

(Keep in mind that you might need to order/sort before, depending on your data)

EDIT: As mentioned by the questioner, use df.groupby('id').head(2).reset_index(drop=True) to remove the multindex and flatten the results.

>>> df.groupby('id').head(2).reset_index(drop=True)
    id  value
0   1      1
1   1      2
2   2      1
3   2      2
4   3      1
5   4      1

You need to use the jQuery AJAX or XMLHttpRequest() for post the data to the server. After data posting you can redirect your page to another page by window.location.href.

Example:

 var xhttp = new XMLHttpRequest();
  xhttp.onreadystatechange = function() {
    if (this.readyState == 4 && this.status == 200) {
      window.location.href = 'https://website.com/my-account';
    }
  };
  xhttp.open("POST", "demo_post.asp", true);
  xhttp.send();

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

instance = getattr(modul, class_name)()

Integer is wrapper class and int is primitive data type.Always prefer using Integer in ArrayList.

Slight update to @no1cobla answer. This hides the period. This solution works in IE8+.

.class:after
{
    content: '.';
    visibility: hidden;
}

It could be that the user identity is outdated, especially if you've tried starting a stopped app pool and the next request again fails.

In IIS, go to the Application Pools under the Server, then find the correct Application Pool for your web site, and click on it. On the Advanced Settings menu to the right, select Identity and change it and enter new user and password. Click on your Application Pool again, and select Recycle to restart it.

You can also try looking at the error message in Event Viewer, under Windows Logs, Application, Details tab.

If you are looking for a custom configuration section like following

<CustomApplicationConfig>
        <Credentials Username="itsme" Password="mypassword"/>
        <PrimaryAgent Address="10.5.64.26" Port="3560"/>
        <SecondaryAgent Address="10.5.64.7" Port="3570"/>
        <Site Id="123" />
        <Lanes>
          <Lane Id="1" PointId="north" Direction="Entry"/>
          <Lane Id="2" PointId="south" Direction="Exit"/>
        </Lanes> 
</CustomApplicationConfig>

then you can use my implementation of configuration section so to get started add System.Configuration assembly reference to your project

Look at the each nested elements I used, First one is Credentials with two attributes so lets add it first

Credentials Element

public class CredentialsConfigElement : System.Configuration.ConfigurationElement
    {
        [ConfigurationProperty("Username")]
        public string Username
        {
            get 
            {
                return base["Username"] as string;
            }
        }

        [ConfigurationProperty("Password")]
        public string Password
        {
            get
            {
                return base["Password"] as string;
            }
        }
    }

PrimaryAgent and SecondaryAgent

Both has the same attributes and seem like a Address to a set of servers for a primary and a failover, so you just need to create one element class for both of those like following

public class ServerInfoConfigElement : ConfigurationElement
    {
        [ConfigurationProperty("Address")]
        public string Address
        {
            get
            {
                return base["Address"] as string;
            }
        }

        [ConfigurationProperty("Port")]
        public int? Port
        {
            get
            {
                return base["Port"] as int?;
            }
        }
    }

I'll explain how to use two different element with one class later in this post, let us skip the SiteId as there is no difference in it. You just have to create one class same as above with one property only. let us see how to implement Lanes collection

it is splitted in two parts first you have to create an element implementation class then you have to create collection element class

LaneConfigElement

public class LaneConfigElement : ConfigurationElement
    {
        [ConfigurationProperty("Id")]
        public string Id
        {
            get
            {
                return base["Id"] as string;
            }
        }

        [ConfigurationProperty("PointId")]
        public string PointId
        {
            get
            {
                return base["PointId"] as string;
            }
        }

        [ConfigurationProperty("Direction")]
        public Direction? Direction
        {
            get
            {
                return base["Direction"] as Direction?;
            }
        }
    }

    public enum Direction
    { 
        Entry,
        Exit
    }

you can notice that one attribute of LanElement is an Enumeration and if you try to use any other value in configuration which is not defined in Enumeration application will throw an System.Configuration.ConfigurationErrorsException on startup. Ok lets move on to Collection Definition

[ConfigurationCollection(typeof(LaneConfigElement), AddItemName = "Lane", CollectionType = ConfigurationElementCollectionType.BasicMap)]
    public class LaneConfigCollection : ConfigurationElementCollection
    {
        public LaneConfigElement this[int index]
        {
            get { return (LaneConfigElement)BaseGet(index); }
            set
            {
                if (BaseGet(index) != null)
                {
                    BaseRemoveAt(index);
                }
                BaseAdd(index, value);
            }
        }

        public void Add(LaneConfigElement serviceConfig)
        {
            BaseAdd(serviceConfig);
        }

        public void Clear()
        {
            BaseClear();
        }

        protected override ConfigurationElement CreateNewElement()
        {
            return new LaneConfigElement();
        }

        protected override object GetElementKey(ConfigurationElement element)
        {
            return ((LaneConfigElement)element).Id;
        }

        public void Remove(LaneConfigElement serviceConfig)
        {
            BaseRemove(serviceConfig.Id);
        }

        public void RemoveAt(int index)
        {
            BaseRemoveAt(index);
        }

        public void Remove(String name)
        {
            BaseRemove(name);
        }

    }

you can notice that I have set the AddItemName = "Lane" you can choose whatever you like for your collection entry item, i prefer to use "add" the default one but i changed it just for the sake of this post.

Now all of our nested Elements have been implemented now we should aggregate all of those in a class which has to implement System.Configuration.ConfigurationSection

CustomApplicationConfigSection

public class CustomApplicationConfigSection : System.Configuration.ConfigurationSection
    {
        private static readonly ILog log = LogManager.GetLogger(typeof(CustomApplicationConfigSection));
        public const string SECTION_NAME = "CustomApplicationConfig";

        [ConfigurationProperty("Credentials")]
        public CredentialsConfigElement Credentials
        {
            get
            {
                return base["Credentials"] as CredentialsConfigElement;
            }
        }

        [ConfigurationProperty("PrimaryAgent")]
        public ServerInfoConfigElement PrimaryAgent
        {
            get
            {
                return base["PrimaryAgent"] as ServerInfoConfigElement;
            }
        }

        [ConfigurationProperty("SecondaryAgent")]
        public ServerInfoConfigElement SecondaryAgent
        {
            get
            {
                return base["SecondaryAgent"] as ServerInfoConfigElement;
            }
        }

        [ConfigurationProperty("Site")]
        public SiteConfigElement Site
        {
            get
            {
                return base["Site"] as SiteConfigElement;
            }
        }

        [ConfigurationProperty("Lanes")]
        public LaneConfigCollection Lanes
        {
            get { return base["Lanes"] as LaneConfigCollection; }
        }
    }

Now you can see that we have two properties with name PrimaryAgent and SecondaryAgent both have the same type now you can easily understand why we had only one implementation class against these two element.

Before you can use this newly invented configuration section in your app.config (or web.config) you just need to tell you application that you have invented your own configuration section and give it some respect, to do so you have to add following lines in app.config (may be right after start of root tag).

<configSections>
    <section name="CustomApplicationConfig" type="MyNameSpace.CustomApplicationConfigSection, MyAssemblyName" />
  </configSections>

NOTE: MyAssemblyName should be without .dll e.g. if you assembly file name is myDll.dll then use myDll instead of myDll.dll

to retrieve this configuration use following line of code any where in your application

CustomApplicationConfigSection config = System.Configuration.ConfigurationManager.GetSection(CustomApplicationConfigSection.SECTION_NAME) as CustomApplicationConfigSection;

I hope above post would help you to get started with a bit complicated kind of custom config sections.

Happy Coding :)

****Edit**** To Enable LINQ on LaneConfigCollection you have to implement IEnumerable<LaneConfigElement>

And Add following implementation of GetEnumerator

public new IEnumerator<LaneConfigElement> GetEnumerator()
        {
            int count = base.Count;
            for (int i = 0; i < count; i++)
            {
                yield return base.BaseGet(i) as LaneConfigElement;
            }
        }

for the people who are still confused about how yield really works read this nice article

Two key points taken from above article are

it doesn’t really end the method’s execution. yield return pauses the method execution and the next time you call it (for the next enumeration value), the method will continue to execute from the last yield return call. It sounds a bit confusing I think… (Shay Friedman)

Yield is not a feature of the .Net runtime. It is just a C# language feature which gets compiled into simple IL code by the C# compiler. (Lars Corneliussen)

After instantiating a Formatter I usually set formatter.converter = gmtime. So in order for @unutbu's answer to work in this case you'll need:

class MyFormatter(logging.Formatter):
    def formatTime(self, record, datefmt=None):
        ct = self.converter(record.created)
        if datefmt:
            s = time.strftime(datefmt, ct)
        else:
            t = time.strftime("%Y-%m-%d %H:%M:%S", ct)
            s = "%s.%03d" % (t, record.msecs)
        return s

What you're doing is a static include. A static include is resolved at compile time, and may thus not use a parameter value, which is only known at execution time.

What you need is a dynamic include:

<jsp:include page="..." />

Note that you should use the JSP EL rather than scriptlets. It also seems that you're implementing a central controller with index.jsp. You should use a servlet to do that instead, and dispatch to the appropriate JSP from this servlet. Or better, use an existing MVC framework like Stripes or Spring MVC.

I wrote a blog entry to answer my own question

Adding html attributes support for Templates - ASP.Net MVC 2.0 Beta

You write like this-:

xAxis: {
        type: 'datetime',
        dateTimeLabelFormats: {
           day: '%d %b %Y'    //ex- 01 Jan 2016
        }
}

also check for other datetime format

To both style the hover color and avoid the OS default color in Firefox, you need to add a box-shadow to both the select option and select option:hover declarations, setting the color of the box-shadow on "select option" to the menu background color.

select option {
  background: #f00; 
  color: #fff; 
  box-shadow: inset 20px 20px #f00
} 

select option:hover {
  color: #000; 
  box-shadow: inset 20px 20px #00f;
}

numberList=[16,19,42,43,74,66]

largest = numberList[0]

for num2 in numberList:

    if num2 > largest:

        largest=num2

print(largest)

gives largest number out of the numberslist without using a Max statement

The fragment already has startActivityForResult, which would call onActivityResult in the fragment if you use it, instead of getActivity()...

If the script is in the head of your HTML document, the body of your HTML document has not yet been created by the browser, regardless of what will eventually be there (the same result occurs if your script is in the HTML file but above the element). When your variable tries to find document.getElementById("status") it does not yet exist, and so it returns a value of null. When you then use the variable later in your code, the initial value (null) is used and not the current one, because nothing has updated the variable.

I didn't want to move my script link out of the HTML head, so instead I did this in my JS file:

var idPost //define a global variable
function updateVariables(){
    idPost = document.getElementById("status").innerHTML; //update the global variable
}

And this in the HTML file:

<body onload="updateVariables()">

If you already have an onload function in place, you can just add the additional line to it or call the function.

If you don't want the variable to be global, define it locally in the function that you are trying to run and make sure the function is not called before the page has fully loaded.

$(document).ready(function() {

  // place this within dom ready function
  function showpanel() {     
    $(".navigation").hide();
    $(".page").children(".panel").fadeIn(1000);
 }

 // use setTimeout() to execute
 setTimeout(showpanel, 1000)

});

For more see here

This works very well.

ArrayList<String[]> a = new ArrayList<String[]>();
    a.add(new String[3]);
    a.get(0)[0] = "Zubair";
    a.get(0)[1] = "Borkala";
    a.get(0)[2] = "Kerala";
System.out.println(a.get(0)[1]);

Result will be

Borkala

this will point to the <ul> selected by .nav-list. You can use delegation instead!

$('.nav-list').on('click', 'li', function() {
    $('.nav-list li.active').removeClass('active');
    $(this).addClass('active');
});

I had the following configuration:

• NGINX (running user: nginx)
• PHP-FPM

And applied permissions correctly as @bgies suggested in the accepted answer. The problem in my case was the php-fpm's configured running user and group which was originally apache.

If you're using NGINX with php-fpm, you should open php-fpm's config file:

nano /etc/php-fpm.d/www.config

And replace user and group options' value with one NGINX is configured to work with; in my case, both were nginx:

... ; Unix user/group of processes ; Note: The user is mandatory. If the group is not set, the default user's group ; will be used. ; RPM: apache Choosed to be able to access some dir as httpd user = nginx ; RPM: Keep a group allowed to write in log dir. group = nginx ...

Save it and restart nginx and php-fpm services.

Don't code, Xcode !

Instead of using UILabel for this specific matter, I suggest you to take a look at UIButton. It gives, out of the box, the ability to set Content Insets (top, left, bottom, right) in the Size inspector. Set the desired margins, after that disable the button right in Xcode and done.

Maybe the dot notation for current folder is incorrect?

Print the result of File.getCanonicalFile() to check the path.

Can anyone explain to me why src isn't the current folder?

Your IDE is setting the class-path when invoking the JVM.

E.G. (reaches for Netbeans) If you select menus File | Project Properties (all classes) you might see something similar to:

It is the Working Directory that is of interest here.

Check out the GLPaint example.

http://developer.apple.com/library/ios/#samplecode/GLPaint/Introduction/Intro.html

Two examples of filtering out multiple lines with grep:

Put this in filename.txt:

abc
def
ghi
jkl

grep command using -E option with a pipe between tokens in a string:

grep -Ev 'def|jkl' filename.txt

prints:

abc
ghi

Command using -v option with pipe between tokens surrounded by parens:

egrep -v '(def|jkl)' filename.txt

prints:

abc
ghi

Set a transparent border and then change it:

.default{
border: 2px solid transparent;
}

.new{
border: 2px solid red;
}

Upon trying all the answers above, I found that using "RequestsCookieJar" instead of the regular CookieJar for subsequent requests fixed my problem.

import requests
import json

# The Login URL
authUrl = 'https://whatever.com/login'

# The subsequent URL
testUrl = 'https://whatever.com/someEndpoint'

# Logout URL
testlogoutUrl = 'https://whatever.com/logout'

# Whatever you are posting
login_data =  {'formPosted':'1', 
               'login_email':'[email protected]', 
               'password':'pw'
               }

# The Authentication token or any other data that we will receive from the Authentication Request. 
token = ''

# Post the login Request
loginRequest = requests.post(authUrl, login_data)
print("{}".format(loginRequest.text))

# Save the request content to your variable. In this case I needed a field called token. 
token = str(json.loads(loginRequest.content)['token'])  # or ['access_token']
print("{}".format(token))

# Verify Successful login
print("{}".format(loginRequest.status_code))

# Create your Requests Cookie Jar for your subsequent requests and add the cookie
jar = requests.cookies.RequestsCookieJar()
jar.set('LWSSO_COOKIE_KEY', token)

# Execute your next request(s) with the Request Cookie Jar set
r = requests.get(testUrl, cookies=jar)
print("R.TEXT: {}".format(r.text))
print("R.STCD: {}".format(r.status_code))

# Execute your logout request(s) with the Request Cookie Jar set
r = requests.delete(testlogoutUrl, cookies=jar)
print("R.TEXT: {}".format(r.text))  # should show "Request Not Authorized"
print("R.STCD: {}".format(r.status_code))  # should show 401

/\S/.test(string) returns true if and only if there's a non-space character in string. Tab and newline count as spaces.

I've listed a complete JavaScript for creating an MD5 at the bottom but it's really pointless without a secure connection for several reasons.

If you MD5 the password and store that MD5 in your database then the MD5 is the password. People can tell exactly what's in your database. You've essentially just made the password a longer string but it still isn't secure if that's what you're storing in your database.

If you say, "Well I'll MD5 the MD5" you're missing the point. By looking at the network traffic, or looking in your database, I can spoof your website and send it the MD5. Granted this is a lot harder than just reusing a plain text password but it's still a security hole.

Most of all though you can't salt the hash client side without sending the salt over the 'net unencrypted therefore making the salting pointless. Without a salt or with a known salt I can brute force attack the hash and figure out what the password is.

If you are going to do this kind of thing with unencrypted transmissions you need to use a public key/private key encryption technique. The client encrypts using your public key then you decrypt on your end with your private key then you MD5 the password (using a user unique salt) and store it in your database. Here's a JavaScript GPL public/private key library.

Anyway, here is the JavaScript code to create an MD5 client side (not my code):

In API level 29, WifiManager.enableNetwork() method is deprecated. As per Android API documentation(check here):

1. See WifiNetworkSpecifier.Builder#build() for new mechanism to trigger connection to a Wi-Fi network.
2. See addNetworkSuggestions(java.util.List), removeNetworkSuggestions(java.util.List) for new API to add Wi-Fi networks for consideration when auto-connecting to wifi. Compatibility Note: For applications targeting Build.VERSION_CODES.Q or above, this API will always return false.

From API level 29, to connect to WiFi network, you will need to use WifiNetworkSpecifier. You can find example code at https://developer.android.com/reference/android/net/wifi/WifiNetworkSpecifier.Builder.html#build()

The previous posts information is correct, but it does not have details on how to link containers, which should be connected as "external_links".

Hope this example make more clear to you:

• Suppose you have app1/docker-compose.yml, with two services (svc11 and svc12), and app2/docker-compose.yml with two more services (svc21 and svc22) and suppose you need to connect in a crossed fashion:

• svc11 needs to connect to svc22's container

• svc21 needs to connect to svc11's container.

So the configuration should be like this:

this is app1/docker-compose.yml:

version: '2'
services:
    svc11:
        container_name: container11
        [..]
        networks:
            - default # this network
            - app2_default # external network
        external_links:
            - container22:container22
        [..]
    svc12:
       container_name: container12
       [..]

networks:
    default: # this network (app1)
        driver: bridge
    app2_default: # external network (app2)
        external: true

this is app2/docker-compose.yml:

version: '2'
services:
    svc21:
        container_name: container21
        [..]
        networks:
            - default # this network (app2)
            - app1_default # external network (app1)
        external_links:

to modify more css property values, you may use css object. such as:

hilight_css = {"border-bottom-color":"red", 
               "background-color":"#000"};
$(".msg").css(hilight_css);

but if the modification code is bloated. you should consider the approach March suggested. do it this way:

first, in your css file:

.hilight { border-bottom-color:red; background-color:#000; }
.msg { /* something to make it notifiable */ }

second, in your js code:

$(".msg").addClass("hilight");
// to bring message block to normal
$(".hilight").removeClass("hilight");

if ie 6 is not an issue, you can chain these classes to have more specific selectors.

The URL file://[servername]/[sharename] should open an explorer window to the shared folder on the network.

$('input:radio[checked=false]');

this will also work

input:radio:not(:checked)

or

:radio:not(:checked)

Had the same problem...im also new at javascript but i solved this with req.connection.remoteAddress; that gave me th IP address (but in ipv6 format ::ffff.192.168.0.101 ) and then .slice to remove the 7 first digits.

var ip = req.connection.remoteAddress;

if (ip.length < 15) 
{   
   ip = ip;
}
else
{
   var nyIP = ip.slice(7);
   ip = nyIP;
}

Could not add as comment because of size: Not sure if this is true, besides updating retention.ms and retention.bytes, but I noticed topic cleanup policy should be "delete" (default), if "compact", it is going to hold on to messages longer, i.e., if it is "compact", you have to specify delete.retention.ms also.

./bin/kafka-configs.sh --zookeeper localhost:2181 --describe --entity-name test-topic-3-100 --entity-type topics
Configs for topics:test-topic-3-100 are retention.ms=1000,delete.retention.ms=10000,cleanup.policy=delete,retention.bytes=1

Also had to monitor earliest/latest offsets should be same to confirm this successfully happened, can also check the du -h /tmp/kafka-logs/test-topic-3-100-*

./bin/kafka-run-class.sh kafka.tools.GetOffsetShell --broker-list "BROKER:9095" --topic test-topic-3-100 --time -1 | awk -F ":" '{sum += $3} END {print sum}' 26599762

./bin/kafka-run-class.sh kafka.tools.GetOffsetShell --broker-list "BROKER:9095" --topic test-topic-3-100 --time -2 | awk -F ":" '{sum += $3} END {print sum}' 26599762

The other problem is, you have to get current config first so you remember to revert after deletion is successful: ./bin/kafka-configs.sh --zookeeper localhost:2181 --describe --entity-name test-topic-3-100 --entity-type topics

Assuming you can put ID's on the inputs:

$('#name').change(function() {
    $('#firstname').val($(this).val());
});

JSFiddle Example

Otherwise you'll have to select using the names:

$('input[name="name"]').change(function() {
    $('input[name="firstname"]').val($(this).val());
});

As what has already been mentioned by others, what behind the mystery is Branch Predictor.

I'm not trying to add something but explaining the concept in another way. There is a concise introduction on the wiki which contains text and diagram. I do like the explanation below which uses a diagram to elaborate the Branch Predictor intuitively.

In computer architecture, a branch predictor is a digital circuit that tries to guess which way a branch (e.g. an if-then-else structure) will go before this is known for sure. The purpose of the branch predictor is to improve the flow in the instruction pipeline. Branch predictors play a critical role in achieving high effective performance in many modern pipelined microprocessor architectures such as x86.

Two-way branching is usually implemented with a conditional jump instruction. A conditional jump can either be "not taken" and continue execution with the first branch of code which follows immediately after the conditional jump, or it can be "taken" and jump to a different place in program memory where the second branch of code is stored. It is not known for certain whether a conditional jump will be taken or not taken until the condition has been calculated and the conditional jump has passed the execution stage in the instruction pipeline (see fig. 1).

Based on the described scenario, I have written an animation demo to show how instructions are executed in a pipeline in different situations.

1. Without the Branch Predictor.

Without branch prediction, the processor would have to wait until the conditional jump instruction has passed the execute stage before the next instruction can enter the fetch stage in the pipeline.

The example contains three instructions and the first one is a conditional jump instruction. The latter two instructions can go into the pipeline until the conditional jump instruction is executed.

It will take 9 clock cycles for 3 instructions to be completed.

2. Use Branch Predictor and don't take a conditional jump. Let's assume that the predict is not taking the conditional jump.

It will take 7 clock cycles for 3 instructions to be completed.

3. Use Branch Predictor and take a conditional jump. Let's assume that the predict is not taking the conditional jump.

It will take 9 clock cycles for 3 instructions to be completed.

The time that is wasted in case of a branch misprediction is equal to the number of stages in the pipeline from the fetch stage to the execute stage. Modern microprocessors tend to have quite long pipelines so that the misprediction delay is between 10 and 20 clock cycles. As a result, making a pipeline longer increases the need for a more advanced branch predictor.

As you can see, it seems we don't have a reason not to use Branch Predictor.

It's quite a simple demo that clarifies the very basic part of Branch Predictor. If those gifs are annoying, please feel free to remove them from the answer and visitors can also get the live demo source code from BranchPredictorDemo

Plots created using seaborn need to be displayed like ordinary matplotlib plots. This can be done using the

plt.show()

function from matplotlib.

Originally I posted the solution to use the already imported matplotlib object from seaborn (sns.plt.show()) however this is considered to be a bad practice. Therefore, simply directly import the matplotlib.pyplot module and show your plots with

import matplotlib.pyplot as plt
plt.show()

If the IPython notebook is used the inline backend can be invoked to remove the necessity of calling show after each plot. The respective magic is

%matplotlib inline

You can do this way:

String cert = DataAccessUtils.singleResult(
    jdbcTemplate.queryForList(
        "select ID_NMB_SRZ from codb_owner.TR_LTM_SLS_RTN where ID_STR_RT = :id_str_rt and ID_NMB_SRZ = :id_nmb_srz",
        new MapSqlParameterSource()
            .addValue("id_str_rt", "999")
            .addValue("id_nmb_srz", "60230009999999"),
        String.class
    )
)

DataAccessUtils.singleResult + queryForList:

• returns null for empty result
• returns single result if exactly 1 row found
• throws exception if more then 1 rows found. Should not happen for primary key / unique index search

DataAccessUtils.singleResult

I found a way that works for me. It is not 100% exact but it eliminates all strings that contain more than just the word I am looking for because I check for the string not containing individual spaces too. By the way you don't need these " ". jQuery knows you are looking for a string. Make sure you only have one space in the :contains( ) part otherwise it won't work.

<p>hello</p>
<p>hello world</p>
$('p:contains(hello):not(:contains( ))').css('font-weight', 'bold');

And yes I know it won't work if you have stuff like <p>helloworld</p>

finally solved my problem.

I created a new project in XCode with the sources and changed the C++ Standard Library from the default libc++ to libstdc++ as in this and this.

Have a look at this HTML5 rocks post - http://www.html5rocks.com/en/mobile/fullscreen/ basically you can use JS, or the Fullscreen API (better option IMO) or add some metadata to the head to indicate that the page is a webapp

You can put the img tag in a div tag and do both, but I would recommend against scaling images in the browser. It does a lousy job most of the time because browsers have very simplistic scaling algorithms. Better to do your scaling in Photoshop or ImageMagick first, then serve it up to the client nice and pretty.

Use slf4android lib.
It's simple implementation of slf4j api using android java.util.logging.*.

Features:

• logging to file out of the box
• logging to any other destination by LoggerConfiguration.configuration().addHandlerToLogger
• shake your device to send logs with screenshot via email
• really small, it tooks only ~55kB

slf4android is maintained mainly by @miensol.

Either two different IP addresses (like recommended) or one web server is reverse-proxying the other (which is listening on a port <>80).

For instance: Apache listens on port 80, IIS on port 8080. Every http request goes to Apache first (of course). You can then decide to forward every request to a particular (named virtual) domain or every request that contains a particular directory (e.g. http://www.example.com/winapp/) to the IIS.

Advantage of this concept is that you have only one server listening to the public instead of two, you are more flexible as with two distinct servers.

Drawbacks: some webapps are crappily designed and a real pain in the ass to integrate into a reverse-proxy infrastructure. A working IIS webapp is dependent on a working Apache, so we have some inter-dependencies.

You have to add a CSP meta tag in the head section of your app's index.html

As per https://github.com/apache/cordova-plugin-whitelist#content-security-policy

Content Security Policy

Controls which network requests (images, XHRs, etc) are allowed to be made (via webview directly).

On Android and iOS, the network request whitelist (see above) is not able to filter all types of requests (e.g. <video> & WebSockets are not blocked). So, in addition to the whitelist, you should use a Content Security Policy <meta> tag on all of your pages.

On Android, support for CSP within the system webview starts with KitKat (but is available on all versions using Crosswalk WebView).

Here are some example CSP declarations for your .html pages:

<!-- Good default declaration:
    * gap: is required only on iOS (when using UIWebView) and is needed for JS->native communication
    * https://ssl.gstatic.com is required only on Android and is needed for TalkBack to function properly
    * Disables use of eval() and inline scripts in order to mitigate risk of XSS vulnerabilities. To change this:
        * Enable inline JS: add 'unsafe-inline' to default-src
        * Enable eval(): add 'unsafe-eval' to default-src
-->
<meta http-equiv="Content-Security-Policy" content="default-src 'self' data: gap: https://ssl.gstatic.com; style-src 'self' 'unsafe-inline'; media-src *">

<!-- Allow requests to foo.com -->
<meta http-equiv="Content-Security-Policy" content="default-src 'self' foo.com">

<!-- Enable all requests, inline styles, and eval() -->
<meta http-equiv="Content-Security-Policy" content="default-src *; style-src 'self' 'unsafe-inline'; script-src 'self' 'unsafe-inline' 'unsafe-eval'">

<!-- Allow XHRs via https only -->
<meta http-equiv="Content-Security-Policy" content="default-src 'self' https:">

<!-- Allow iframe to https://cordova.apache.org/ -->
<meta http-equiv="Content-Security-Policy" content="default-src 'self'; frame-src 'self' https://cordova.apache.org">

And there are a couple of other cases where if you catch an Error, you have to rethrow it. For example ThreadDeath should never be caught, it can cause big problem is you catch it in a contained environment (eg. an application server) :

An application should catch instances of this class only if it must clean up after being terminated asynchronously. If ThreadDeath is caught by a method, it is important that it be rethrown so that the thread actually dies.

The answer above not work for me. I just solved it by appending the absolute path of the module which not found to the sys.path at top of the test_xxx.py (your test module), like:

import sys
sys.path.append('path')

How about:

public static final byte[] intToByteArray(int value) {
    return new byte[] {
            (byte)(value >>> 24),
            (byte)(value >>> 16),
            (byte)(value >>> 8),
            (byte)value};
}

The idea is not mine. I've taken it from some post on dzone.com.

As others have mentioned, perhaps the main advantage of matrix was that it provided a convenient notation for matrix multiplication.

However, in Python 3.5 there is finally a dedicated infix operator for matrix multiplication: @.

With recent NumPy versions, it can be used with ndarrays:

A = numpy.ones((1, 3))
B = numpy.ones((3, 3))
A @ B

So nowadays, even more, when in doubt, you should stick to ndarray.

As said above -- use Euclidean distance.

from math import hypot

def in_radius(c_x, c_y, r, x, y):
    return math.hypot(c_x-x, c_y-y) <= r

An alternative solution would be to use some sort of regex:

for example:

    String s = "apple car 04:48 05:18 05:46 06:16 06:46 07:16 07:46 16:46 17:16 17:46 18:16 18:46 19:16";
    String results=  s.replaceAll("[0-9]", "").replaceAll(" :", ""); //first removing all the numbers then remove space followed by :
    System.out.println(results); // output 9
    System.out.println(results.length());// output "apple car"

Your code looks correct but sometimes google blocks an IP when you try to send a email from an unusual location. You can try to unblock it by visiting https://accounts.google.com/DisplayUnlockCaptcha from the IP and following the prompts.

To get the id of the parent div:

$(buttonSelector).parents('div:eq(0)').attr('id');

Also, you can refactor your code quite a bit:

$('button').click( function() {
 var correct = Number($(this).attr('rel'));
 validate(Number($(this).siblings('input').val()), correct);
 $(this).parents('div:eq(0)').html(feedback);
});

Now there is no need for a button-class

explanation
eq(0), means that you will select one element from the jQuery object, in this case element 0, thus the first element. http://docs.jquery.com/Selectors/eq#index
$(selector).siblings(siblingsSelector) will select all siblings (elements with the same parent) that match the siblingsSelector http://docs.jquery.com/Traversing/siblings#expr
$(selector).parents(parentsSelector) will select all parents of the elements matched by selector that match the parent selector. http://docs.jquery.com/Traversing/parents#expr
Thus: $(selector).parents('div:eq(0)'); will match the first parent div of the elements matched by selector.

You should have a look at the jQuery docs, particularly selectors and traversing:

• http://docs.jquery.com/
• http://docs.jquery.com/Selectors
• http://docs.jquery.com/Traversing

you can get the current project path use System.getProperty("user.dir")

in that method you write Key name to get your different-different paths, and if you don't know key, you can find all property use of System.getProperties() this method is return all property with key. and you can find key name manually from it.

and write System.getProperty("KEY NAME")

and get your require path.

You could put an index on MemberType.

The other answers will break if output of command contains spaces (which is rather frequent) or glob characters like *, ?, [...].

To get the output of a command in an array, with one line per element, there are essentially 3 ways:

1. With Bash=4 use mapfile—it's the most efficient:

   mapfile -t my_array < <( my_command )
   

2. Otherwise, a loop reading the output (slower, but safe):

   my_array=()
   while IFS= read -r line; do
       my_array+=( "$line" )
   done < <( my_command )
   

3. As suggested by Charles Duffy in the comments (thanks!), the following might perform better than the loop method in number 2:

   IFS=$'\n' read -r -d '' -a my_array < <( my_command && printf '\0' )
   

   Please make sure you use exactly this form, i.e., make sure you have the following:

   • IFS=$'\n' on the same line as the read statement: this will only set the environment variable IFS for the read statement only. So it won't affect the rest of your script at all. The purpose of this variable is to tell read to break the stream at the EOL character \n.
   • -r: this is important. It tells read to not interpret the backslashes as escape sequences.
   • -d '': please note the space between the -d option and its argument ''. If you don't leave a space here, the '' will never be seen, as it will disappear in the quote removal step when Bash parses the statement. This tells read to stop reading at the nil byte. Some people write it as -d $'\0', but it is not really necessary. -d '' is better.
   • -a my_array tells read to populate the array my_array while reading the stream.
   • You must use the printf '\0' statement after my_command, so that read returns 0; it's actually not a big deal if you don't (you'll just get an return code 1, which is okay if you don't use set -e – which you shouldn't anyway), but just bear that in mind. It's cleaner and more semantically correct. Note that this is different from printf '', which doesn't output anything. printf '\0' prints a null byte, needed by read to happily stop reading there (remember the -d '' option?).

If you can, i.e., if you're sure your code will run on Bash=4, use the first method. And you can see it's shorter too.

If you want to use read, the loop (method 2) might have an advantage over method 3 if you want to do some processing as the lines are read: you have direct access to it (via the $line variable in the example I gave), and you also have access to the lines already read (via the array ${my_array[@]} in the example I gave).

Note that mapfile provides a way to have a callback eval'd on each line read, and in fact you can even tell it to only call this callback every N lines read; have a look at help mapfile and the options -C and -c therein. (My opinion about this is that it's a little bit clunky, but can be used sometimes if you only have simple things to do — I don't really understand why this was even implemented in the first place!).

Now I'm going to tell you why the following method:

my_array=( $( my_command) )

is broken when there are spaces:

$ # I'm using this command to test:
$ echo "one two"; echo "three four"
one two
three four
$ # Now I'm going to use the broken method:
$ my_array=( $( echo "one two"; echo "three four" ) )
$ declare -p my_array
declare -a my_array='([0]="one" [1]="two" [2]="three" [3]="four")'
$ # As you can see, the fields are not the lines
$
$ # Now look at the correct method:
$ mapfile -t my_array < <(echo "one two"; echo "three four")
$ declare -p my_array
declare -a my_array='([0]="one two" [1]="three four")'
$ # Good!

Then some people will then recommend using IFS=$'\n' to fix it:

$ IFS=$'\n'
$ my_array=( $(echo "one two"; echo "three four") )
$ declare -p my_array
declare -a my_array='([0]="one two" [1]="three four")'
$ # It works!

But now let's use another command, with globs:

$ echo "* one two"; echo "[three four]"
* one two
[three four]
$ IFS=$'\n'
$ my_array=( $(echo "* one two"; echo "[three four]") )
$ declare -p my_array
declare -a my_array='([0]="* one two" [1]="t")'
$ # What?

That's because I have a file called t in the current directory… and this filename is matched by the glob [three four]… at this point some people would recommend using set -f to disable globbing: but look at it: you have to change IFS and use set -f to be able to fix a broken technique (and you're not even fixing it really)! when doing that we're really fighting against the shell, not working with the shell.

$ mapfile -t my_array < <( echo "* one two"; echo "[three four]")
$ declare -p my_array
declare -a my_array='([0]="* one two" [1]="[three four]")'

here we're working with the shell!

C++11:

std::map< std::string, std::map<std::string, std::string> > m;
m["name1"]["value1"] = "data1";
m["name1"]["value2"] = "data2";
m["name2"]["value1"] = "data1";
m["name2"]["value2"] = "data2";
m["name3"]["value1"] = "data1";
m["name3"]["value2"] = "data2";

for (auto i : m)
    for (auto j : i.second)
        cout << i.first.c_str() << ":" << j.first.c_str() << ":" << j.second.c_str() << endl;

output:

name1:value1:data1
name1:value2:data2
name2:value1:data1
name2:value2:data2
name3:value1:data1
name3:value2:data2

You're not assigning the parsed float back to your value var:

value = parseFloat(value).toFixed(2);

should fix things up.

Method overriding is when a child class redefines the same method as a parent class, with the same parameters. For example, the standard Java class java.util.LinkedHashSet extends java.util.HashSet. The method add() is overridden in LinkedHashSet. If you have a variable that is of type HashSet, and you call its add() method, it will call the appropriate implementation of add(), based on whether it is a HashSet or a LinkedHashSet. This is called polymorphism.

Method overloading is defining several methods in the same class, that accept different numbers and types of parameters. In this case, the actual method called is decided at compile-time, based on the number and types of arguments. For instance, the method System.out.println() is overloaded, so that you can pass ints as well as Strings, and it will call a different version of the method.

No new line:

File.AppendAllText("file.txt", DateTime.Now.ToString());

and then to get a new line after OK:

File.AppendAllText("file.txt", string.Format("{0}{1}", "OK", Environment.NewLine));

You need call in.close(), in a finally block to ensure it occurs.

From the Eclipse documentation, here is why it flags this particular problem (emphasis mine):

Classes implementing the interface java.io.Closeable (since JDK 1.5) and java.lang.AutoCloseable (since JDK 1.7) are considered to represent external resources, which should be closed using method close(), when they are no longer needed.

The Eclipse Java compiler is able to analyze whether code using such types adheres to this policy.

...

The compiler will flag [violations] with "Resource leak: 'stream' is never closed".

Full explanation here.

If your whole JavaScript code gets processed by PHP, then you can do it just like that.

If you have individual .js files, and you don't want PHP to process them (for example, for caching reasons), then you can just pass variables around in JavaScript.

For example, in your index.php (or wherever you specify your layout), you'd do something like this:

<script type="text/javascript">
    var my_var = <?php echo json_encode($my_var); ?>;
</script>

You could then use my_var in your JavaScript files.

This method also lets you pass other than just simple integer values, as json_encode() also deals with arrays, strings, etc. correctly, serialising them into a format that JavaScript can use.

Try like this,

>>> s = set([1,2,3])
>>> s = list(s)
>>> s
[1, 2, 3]

>>> str = ', '.join(str(e) for e in s)
>>> str = 'set(%s)' % str
>>> str
'set(1, 2, 3)'

The differences between these values always come down to detailed language-specific rules. What you learn for PHP isn't necessarily true for Python, or Perl, or C, etc. While it is valuable to learn the rules for the language(s) you're working with, relying on them too much is asking for trouble. The trouble comes when the next programmer needs to maintain your code and you've used some construct that takes advantage of some little detail of Null vs. False (for example). Your code should look correct (and conversely, wrong code should look wrong).

The condition below:

//Element[@attribute1="abc" and @attribute2="xyz" and Data]

checks for the existence of the element Data within Element and not for element value Data.

Instead you can use

//Element[@attribute1="abc" and @attribute2="xyz" and text()="Data"]

In addition to the answers above:

If you created/edited your .sh script file in Windows, make sure it was saved with line ending in Unix format. By default many editors in Windows will convert Unix line endings to Windows format and Linux will not recognize shebang (#!/bin/sh) at the beginning of the file. So Linux will produce the error message like if there is no shebang.

Tips:

• If you use Notepad++, you need to click "Edit/EOL Conversion/UNIX (LF)"
• If you use Visual Studio, I would suggest installing "End Of Line" plugin. Then you can make line endings visible by pressing Ctrl-R, Ctrl-W. And to set Linux style endings you can press Ctrl-R, Ctrl-L. For Windows style, press Ctrl-R, Ctrl-C.

This method will use the LocationManager service.

Source Link

//Check GPS Status true/false
public static boolean checkGPSStatus(Context context){
    LocationManager manager = (LocationManager) context.getSystemService(Context.LOCATION_SERVICE );
    boolean statusOfGPS = manager.isProviderEnabled(LocationManager.GPS_PROVIDER);
    return statusOfGPS;
};

Use GREATEST()

E.g.:

SELECT GREATEST(2,1);

Note: Whenever if any single value contains null at that time this function always returns null (Thanks to user @sanghavi7)

You can also use CygWin and install the cURL package. It works very well and flawlessly!!

Not sure if this is still relevant, but I use this way

Public bEnableEvents As Boolean
Public bclickok As Boolean
Public booRestoreErrorChecking As Boolean   'put this at the top of the module

 Private Declare Function apiGetComputerName Lib "kernel32" Alias _
"GetComputerNameA" (ByVal lpBuffer As String, nSize As Long) As Long
Private Declare Function apiGetUserName Lib "advapi32.dll" Alias _
"GetUserNameA" (ByVal lpBuffer As String, nSize As Long) As Long

Function GetUserID() As String
' Returns the network login name
On Error Resume Next
Dim lngLen As Long, lngX As Long
Dim strUserName As String
strUserName = String$(254, 0)
lngLen = 255
lngX = apiGetUserName(strUserName, lngLen)
If lngX <> 0 Then
    GetUserID = Left$(strUserName, lngLen - 1)
Else
    GetUserID = ""
End If
Exit Function
End Function

This next bit I save file as PDF, but can change to suit

Public Sub SaveToDesktop()
Dim LoginName As String
LoginName = UCase(GetUserID)

ChDir "C:\Users\" & LoginName & "\Desktop\"
Debug.Print LoginName
ActiveSheet.ExportAsFixedFormat Type:=xlTypePDF, Filename:= _
    "C:\Users\" & LoginName & "\Desktop\MyFileName.pdf", Quality:=xlQualityStandard, _
    IncludeDocProperties:=True, IgnorePrintAreas:=False, OpenAfterPublish:= _
    True
End Sub

Ok, this is actually four different question. I'll address them one by one:

are both equals for the compiler? (speed, perf...)

Yes. The pointer dereferenciation and decay from type int (*)[100][280] to int (*)[280] is always a noop to your CPU. I wouldn't put it past a bad compiler to generate bogus code anyways, but a good optimizing compiler should compile both examples to the exact same code.

is one of these solutions eating more memory than the other?

As a corollary to my first answer, no.

what is the more frequently used by developers?

Definitely the variant without the extra (*pointer) dereferenciation. For C programmers it is second nature to assume that any pointer may actually be a pointer to the first element of an array.

what is the best way, the 1st or the 2nd?

That depends on what you optimize for:

• Idiomatic code uses variant 1. The declaration is missing the outer dimension, but all uses are exactly as a C programmer expects them to be.

• If you want to make it explicit that you are pointing to an array, you can use variant 2. However, many seasoned C programmers will think that there's a third dimension hidden behind the innermost *. Having no array dimension there will feel weird to most programmers.

Download the code from github into the node_modules directory

var moduleName = require("<name of directory>")

that should do it.

if the module has dependancies and has a package.json, open the module and enter npm install.

Hope this helps

We can create a tag for some past commit:

git tag [tag_name] [reference_of_commit]

eg:

git tag v1.0 5fcdb03

querySelector() matched the id in document. You must write id of password in .html

Then pass it to querySelector() with #symbol & .value property.

Example:

let myVal = document.querySelector('#pwd').value

UPDATE:

Okay, now I definitely have the solution:

files=$(ls xorg-x11-fonts* 2> /dev/null | wc -l)
if [ "$files" != "0" ]
then
   echo "Exists"
else
    echo "None found."
fi

> Exists

You can fix this issue without opening the storyboard as a source. This warning is triggered by UILabels if numberOfLines !=1 and deployment target is < 8.0

HOW TO FIND IT?

1. Go to Issue Navigator (CMD+8) and Select latest built with the warning
2. Locate the warning(s) (search for "Automatic Preferred Max Layout") and press expand button on the right
   
3. Find the Object ID of the UILabel
4. Open the Storyboard and SEARCH (CMD+f) for the object. It will SELECT AND HIGHLIGHT the UILabel
5. Set Preferred Width = 0 "Explicit" as others suggested

I solved the problem this way:

• On the orange WAMP icon, click Apache > Service > Test Port 80. Came back with "Port 80 not accessible -- (could be Skype)"
• Sign out from Skype and close program.
• Click orange icon and hit Apache > Service > Install Service
• Click orange icon and hit Apache > Service > Start Service
• Click orange icon and hit Put Online
• Icon turns green and service is started and online

Java doesn't have delegates and is proud of it :). From what I read here I found in essence 2 ways to fake delegates: 1. reflection; 2. inner class

Reflections are slooooow! Inner class does not cover the simplest use-case: sort function. Do not want to go into details, but the solution with inner class basically is to create a wrapper class for an array of integers to be sorted in ascending order and an class for an array of integers to be sorted in descending order.

preventDefault is what you're looking for. To just block the button from submitting

<Button onClick={this.onClickButton} ...

code

onClickButton (event) {
  event.preventDefault();
}

If you have a form which you want to handle in a custom way you can capture a higher level event onSubmit which will also stop that button from submitting.

<form onSubmit={this.onSubmit}>

and above in code

onSubmit (event) {
  event.preventDefault();

  // custom form handling here
}

post in http
Put http.request.method == "POST" in the display filter of wireshark to only show POST requests. Click on the packet

0.1 second Google search:

BOOL DirectoryExists(const char* dirName) {
  DWORD attribs = ::GetFileAttributesA(dirName);
  if (attribs == INVALID_FILE_ATTRIBUTES) {
    return false;
  }
  return (attribs & FILE_ATTRIBUTE_DIRECTORY);
}

Instead of

extends Fragment

use

extends android.support.v4.app.Fragment 

This works for me. for *API14 and above

Iterative development implies revisiting usual waterfall model steps over the course of product lifetime. The stages can even overlap, i.e. while doing end-to-end testing you could already start preparing new requirements.

Incremental development means you roadmap your features and implement them incrementally.

Agile aims at creating "potentially shippable product" after every sprint. How you achieve it is a different story. Agile tries to employ "best" techniques from various fields (e.g. extreme programming). Agile does not exclude running neither incremental nor iterative development.

The quickest way I found is through editing mode:

1. Press yy to copy the line.
2. Then dd to delete the line.
3. Then p to paste the line.

It lets you handle Many to Many relationship. Example:

Table 1: post

post has following columns
____________________
|  ID     |  DATE   |
|_________|_________|
|         |         |
|_________|_________|

Table 2: user

user has the following columns:

____________________
|     ID  |NAME     |
|_________|_________|
|         |         |
|_________|_________|

Join Table lets you create a mapping using:

@JoinTable(
  name="USER_POST",
  joinColumns=@JoinColumn(name="USER_ID", referencedColumnName="ID"),
  inverseJoinColumns=@JoinColumn(name="POST_ID", referencedColumnName="ID"))

will create a table:

____________________
|  USER_ID| POST_ID |
|_________|_________|
|         |         |
|_________|_________|

I don't have experience with Django but the concepts from front-end to back-end and front-end framework to framework are the same.

1. React will consume your Django REST API. Front-ends and back-ends aren't connected in any way. React will make HTTP requests to your REST API in order to fetch and set data.
2. React, with the help of Webpack (module bundler) & Babel (transpiler), will bundle and transpile your Javascript into single or multiple files that will be placed in the entry HTML page. Learn Webpack, Babel, Javascript and React and Redux (a state container). I believe you won't use Django templating but instead allow React to render the front-end.
3. As this page is rendered, React will consume the API to fetch data so React can render it. Your understanding of HTTP requests, Javascript (ES6), Promises, Middleware and React is essential here.

Here are a few things I've found on the web that should help (based on a quick Google search):

• Django and React API Youtube tutorial
• Setting up Django with React (replaced broken link with archive.org link)
• Search for other resources using the bolded terms above. Try "Django React Webpack" first.

Hope this steers you in the right direction! Good luck! Hopefully others who specialize in Django can add to my response.

With async/await and promisification.

const crypto = require('crypto')
const randomBytes = Util.promisify(crypto.randomBytes)
const plain = (await randomBytes(24)).toString('base64').replace(/\W/g, '')

Generates something similar to VjocVHdFiz5vGHnlnwqJKN0NdeHcz8eM

You have it exactly right, all you have to do is set selectedIndex in your ng-click.

ng-click="selectedIndex = 1"

Here is how I implemented a set of buttons that change the ng-view, and highlights the button of the currently selected view.

<div id="sidebar" ng-init="partial = 'main'">
    <div class="routeBtn" ng-class="{selected:partial=='main'}" ng-click="router('main')"><span>Main</span></div>
    <div class="routeBtn" ng-class="{selected:partial=='view1'}" ng-click="router('view1')"><span>Resume</span></div>
    <div class="routeBtn" ng-class="{selected:partial=='view2'}" ng-click="router('view2')"><span>Code</span></div>
    <div class="routeBtn" ng-class="{selected:partial=='view3'}" ng-click="router('view3')"><span>Game</span></div>
  </div>

and this in my controller.

$scope.router = function(endpoint) {
    $location.path("/" + ($scope.partial = endpoint));
};

It can also solve without using any lodash function like this:

let paramsVal = [
    { name: 'foo', input: 'bar' },
    { name: 'baz', input: 'zle' }
];
let output = {};

paramsVal.forEach(({name, input})=>{
  output[name] = input;
})


console.log(output);

Make sure your AndroidManifest file contains a package name in the manifest node. Setting a package name fixed this problem for me.

Hashtable is similar to the HashMap and has a similar interface. It is recommended that you use HashMap, unless you require support for legacy applications or you need synchronisation, as the Hashtables methods are synchronised. So in your case as you are not multi-threading, HashMaps are your best bet.

Very similar to Marc, only difference I would make would be to spool to a parameter like so:

WHENEVER SQLERROR EXIT 1
SET LINES 32000
SET TERMOUT OFF ECHO OFF NEWP 0 SPA 0 PAGES 0 FEED OFF HEAD OFF TRIMS ON TAB OFF
SET SERVEROUTPUT ON

spool &1

-- Code

spool off
exit

And then to call the SQLPLUS as

sqlplus -s username/password@sid @tmp.sql /tmp/output.txt

There's now also Leaflet, which is built with mobile devices in mind.

There is a Quick Start Guide for leaflet. Besides basic features such as markers, with plugins it also supports routing using an external service.

For a simple map, it is IMHO easier and faster to set up than OpenLayers, yet fully configurable and tweakable for more complex uses.

Alternatives

An alternative to this:

async function main() {
  try {
    var quote = await getQuote();
    console.log(quote);
  } catch (error) {
    console.error(error);
  }
}

would be something like this, using promises explicitly:

function main() {
  getQuote().then((quote) => {
    console.log(quote);
  }).catch((error) => {
    console.error(error);
  });
}

or something like this, using continuation passing style:

function main() {
  getQuote((error, quote) => {
    if (error) {
      console.error(error);
    } else {
      console.log(quote);
    }
  });
}

Original example

What your original code does is suspend the execution and wait for the promise returned by getQuote() to settle. It then continues the execution and writes the returned value to var quote and then prints it if the promise was resolved, or throws an exception and runs the catch block that prints the error if the promise was rejected.

You can do the same thing using the Promise API directly like in the second example.

Performance

Now, for the performance. Let's test it!

I just wrote this code - f1() gives 1 as a return value, f2() throws 1 as an exception:

function f1() {
  return 1;
}

function f2() {
  throw 1;
}

Now let's call the same code million times, first with f1():

var sum = 0;
for (var i = 0; i < 1e6; i++) {
  try {
    sum += f1();
  } catch (e) {
    sum += e;
  }
}
console.log(sum);

And then let's change f1() to f2():

var sum = 0;
for (var i = 0; i < 1e6; i++) {
  try {
    sum += f2();
  } catch (e) {
    sum += e;
  }
}
console.log(sum);

This is the result I got for f1:

$ time node throw-test.js 
1000000

real    0m0.073s
user    0m0.070s
sys     0m0.004s

This is what I got for f2:

$ time node throw-test.js 
1000000

real    0m0.632s
user    0m0.629s
sys     0m0.004s

It seems that you can do something like 2 million throws a second in one single-threaded process. If you're doing more than that then you may need to worry about it.

Summary

I wouldn't worry about things like that in Node. If things like that get used a lot then it will get optimized eventually by the V8 or SpiderMonkey or Chakra teams and everyone will follow - it's not like it's not optimized as a principle, it's just not a problem.

Even if it isn't optimized then I'd still argue that if you're maxing out your CPU in Node then you should probably write your number crunching in C - that's what the native addons are for, among other things. Or maybe things like node.native would be better suited for the job than Node.js.

I'm wondering what would be a use case that needs throwing so many exceptions. Usually throwing an exception instead of returning a value is, well, an exception.

The problem is that your PATH does not include the location of the node executable.

You can likely run node as "/usr/local/bin/node".

You can add that location to your path by running the following command to add a single line to your bashrc file:

echo 'export PATH=$PATH:/usr/local/bin' >> $HOME/.bashrc

Instead of saying:

if [ "$cms" != "wordpress" && "$cms" != "meganto" && "$cms" != "typo3" ]; then

say:

if [[ "$cms" != "wordpress" && "$cms" != "meganto" && "$cms" != "typo3" ]]; then

You might also want to refer to Conditional Constructs.

As other answers have stated, this could happend if cp is an alias of cp -i.

You can append a \ before the cp command to use it without alias.

\cp -fR source target

SASS stands for Syntactically Awesome StyleSheets. It is an extension of CSS that adds power and elegance to the basic language. SASS is newly named as SCSS with some chages, but the old one SASS is also there. Before you use SCSS or SASS please see the below difference.

An example of some SCSS and SASS syntax:

SCSS

$font-stack:    Helvetica, sans-serif;
$primary-color: #333;

body {
  font: 100% $font-stack;
  color: $primary-color;
}

//Mixins
@mixin transform($property) {
  -webkit-transform: $property;
      -ms-transform: $property;
          transform: $property;
}

.box { @include transform(rotate(30deg)); }

SASS

$font-stack:    Helvetica, sans-serif
$primary-color: #333

body
  font: 100% $font-stack
  color: $primary-color

//Mixins
=transform($property)
  -webkit-transform: $property
  -ms-transform:     $property
  transform:         $property

.box
  +transform(rotate(30deg))

Output CSS after Compilation(Same for Both)

body {
  font: 100% Helvetica, sans-serif;
  color: #333;
}
//Mixins
.box {
  -webkit-transform: rotate(30deg);
  -ms-transform: rotate(30deg);
  transform: rotate(30deg);
}

I've tested this using the following powershell script and using (,) between the addresses. It worked for me!

$EmailFrom = "<[email protected]>";
$EmailPassword = "<password>";
$EmailTo = "<[email protected]>,<[email protected]>";
$SMTPServer = "<smtp.server.com>";
$SMTPPort = <port>;
$SMTPClient = New-Object Net.Mail.SmtpClient($SmtpServer,$SMTPPort);
$SMTPClient.EnableSsl = $true;
$SMTPClient.Credentials = New-Object System.Net.NetworkCredential($EmailFrom, $EmailPassword);
$Subject = "Notification from XYZ";
$Body = "this is a notification from XYZ Notifications..";
$SMTPClient.Send($EmailFrom, $EmailTo, $Subject, $Body);

You should try using the Grid Template.

Here's what I've used for a two Column Layout of a <ul>

<ul class="list-group row">
     <li class="list-group-item col-xs-6">Row1</li>
     <li class="list-group-item col-xs-6">Row2</li>
     <li class="list-group-item col-xs-6">Row3</li>
     <li class="list-group-item col-xs-6">Row4</li>
     <li class="list-group-item col-xs-6">Row5</li>
</ul>

This worked for me.

I've used the following code a few times and it works sweet:

$("body").click(function(e){ 
    // Check what has been clicked:
    var target = $(e.target); 
    if(target.is("#target")){
    // The target was clicked
    // Do something...
  }
});

Not possible. You can however use a third party javascript library that emulates a popup window, and it will probably look better as well and be less intrusive.

By either escaping those characters with htmlspecialchars, or, perhaps more appropriately, using a library for building XML documents, such as DOMDocument or XMLWriter.

Another alternative would be to use CDATA sections, but then you'd have to look out for occurrences of ]]>.

Take also into consideration that that you must respect the encoding you define for the XML document (by default UTF-8).

Some of the key features of case classes are listed below

1. case classes are immutable.
2. You can instantiate case classes without new keyword.
3. case classes can be compared by value

I had also this problem. Add code like below in the related controller (e.g. UserController)

$users = User::all();
return view('mytemplate.home.homeContent')->with('users',$users);

I assume you're using typescript.

To be extra cautious you can define your type as an array of objects that need to match certain interface:

type MyArrayType = Array<{id: number, text: string}>;

const arr: MyArrayType = [
    {id: 1, text: 'Sentence 1'},
    {id: 2, text: 'Sentence 2'},
    {id: 3, text: 'Sentence 3'},
    {id: 4, text: 'Sentenc4 '},
];

Or short syntax without defining a custom type:

const arr: Array<{id: number, text: string}> = [...];

The following code is functionally equivalent to Jon Skeet's answer.

Tested on .NET 4.5, should work on any earlier version of LINQ.

public static IEnumerable<TSource> DistinctBy<TSource, TKey>(
  this IEnumerable<TSource> source, Func<TSource, TKey> keySelector)
{
  HashSet<TKey> seenKeys = new HashSet<TKey>();
  return source.Where(element => seenKeys.Add(keySelector(element)));
}

Incidentially, check out Jon Skeet's latest version of DistinctBy.cs on Google Code.

Hmm, this seems to be a bit of an old question, but since I've been messing about with Doxygen configuration last few days, while my head's still full of current info let's have a stab at it -

I think the previous answers almost have it:

The missing option is to add COLLABORATION_GRAPH = YES in the Doxyfile. I assume you can do the equivalent thing somewhere in the doxywizard GUI (I don't use doxywizard).

So, as a more complete example, typical "Doxyfile" options related to UML output that I tend to use are:

EXTRACT_ALL          = YES
CLASS_DIAGRAMS      = YES
HIDE_UNDOC_RELATIONS = NO
HAVE_DOT             = YES
CLASS_GRAPH          = YES
COLLABORATION_GRAPH  = YES
UML_LOOK             = YES
UML_LIMIT_NUM_FIELDS = 50
TEMPLATE_RELATIONS   = YES
DOT_GRAPH_MAX_NODES  = 100
MAX_DOT_GRAPH_DEPTH  = 0
DOT_TRANSPARENT      = YES

These settings will generate both "inheritance" (CLASS_GRAPH=YES) and "collaboration" (COLLABORATION_GRAPH=YES) diagrams.

Depending on your target for "deployment" of the doxygen output, setting DOT_IMAGE_FORMAT = svg may also be of use. With svg output the diagrams are "scalable" instead of the fixed resolution of bitmap formats such as .png. Apparently, if viewing the output in browsers other than IE, there is also INTERACTIVE_SVG = YES which will allow "interactive zooming and panning" of the generated svg diagrams. I did try this some time ago, and the svg output was very visually attractive, but at the time, browser support for svg was still a bit inconsistent, so hopefully that situation may have improved lately.

As other comments have mentioned, some of these settings (DOT_GRAPH_MAX_NODES in particular) do have potential performance impacts, so YMMV.

I tend to hate "RTFM" style answers, so apologies for this sentence, but in this case the Doxygen documentation really is your friend, so check out the Doxygen docs on the above mentioned settings- last time I looked you can find the details at http://www.doxygen.nl/manual/config.html.

I got the same problem, I know I wasn't running any other instances, and I could see it with adb devices. I just did a restart of eclipse and it worked.

I won't write your code but what you looking for is something like a jquery dialog

take a look here

jQuery modal-confirmation

$(function() {
    $( "#dialog-confirm" ).dialog({
      resizable: false,
      height:140,
      modal: true,
      buttons: {
        "Delete all items": function() {
          $( this ).dialog( "close" );
        },
        Cancel: function() {
          $( this ).dialog( "close" );
        }
      }
    });
  });

<div id="dialog-confirm" title="Empty the recycle bin?">
  <p>
    <span class="ui-icon ui-icon-alert" style="float:left; margin:0 7px 20px 0;"></span>
    These items will be permanently deleted and cannot be recovered. Are you sure?
  </p>
</div>

In my implementation, the cell I was referencing could have been several options. I used the following format where 'ws' is the current worksheet being edited

For each ws in Activeworkbook.Worksheets
    For i…
       For j...
...
ws.Cells(i, j).Value = "=HYPERLINK(""#'" & SHEET-REF-VAR & "'!" & CELL-REF-VAR & """,""" & SHEET-REF-VAR & """)"

You should be able to see it in the Services panel. Look for a servicename like Sql Server (MSSQLSERVER). The name in the parentheses is your instance name.

This is because the CHARINDEX-1 is returning a -ive value if the look-up for " " (space) is 0. The simplest solution would be to avoid '-ve' by adding

ABS(CHARINDEX(' ', PostCode ) -1))

which will return only +ive values for your length even if CHARINDEX(' ', PostCode ) -1) is a -ve value. Correct me if I'm wrong!

Now there is the pandas_profiling package, which is a more complete alternative to df.describe().

If your pandas dataframe is df, the below will return a complete analysis including some warnings about missing values, skewness, etc. It presents histograms and correlation plots as well.

import pandas_profiling
pandas_profiling.ProfileReport(df)

See the example notebook detailing the usage.

Ok, so here was my process:

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

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

Then I could import it with the keytool:

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

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

    public class ArrayLimitedQueue<E> extends ArrayDeque<E> {

    private int limit;

    public ArrayLimitedQueue(int limit) {
        super(limit + 1);
        this.limit = limit;
    }

    @Override
    public boolean add(E o) {
        boolean added = super.add(o);
        while (added && size() > limit) {
            super.remove();
        }
        return added;
    }

    @Override
    public void addLast(E e) {
        super.addLast(e);
        while (size() > limit) {
            super.removeLast();
        }
    }

    @Override
    public boolean offerLast(E e) {
        boolean added = super.offerLast(e);
        while (added && size() > limit) {
            super.pollLast();
        }
        return added;
    }
}

Maybe this will help:

JSONObject jsonObject = new JSONObject(contents.trim());
Iterator<String> keys = jsonObject.keys();

while(keys.hasNext()) {
    String key = keys.next();
    if (jsonObject.get(key) instanceof JSONObject) {
          // do something with jsonObject here      
    }
}

When you want to make your php value storable, you have to turn it to be a string value, that is what serialize() does. And unserialize() does the reverse thing.

I was working with 3 files: The python script, the image, and the trained model.

Everything worked when I moved these 3 files into their own folder instead of in the directory with the other python scripts.

My typescript solution, maybe it helps you:

type ITreeItem<T> = T & {
    children: ITreeItem<T>[],
};

type IItemKey = string | number;

function createTree<T>(
    flatList: T[],
    idKey: IItemKey,
    parentKey: IItemKey,
): ITreeItem<T>[] {
    const tree: ITreeItem<T>[] = [];

    // hash table.
    const mappedArr = {};
    flatList.forEach(el => {
        const elId: IItemKey = el[idKey];

        mappedArr[elId] = el;
        mappedArr[elId].children = [];
    });

    // also you can use Object.values(mappedArr).forEach(...
    // but if you have element which was nested more than one time
    // you should iterate flatList again:
    flatList.forEach((elem: ITreeItem<T>) => {
        const mappedElem = mappedArr[elem[idKey]];

        if (elem[parentKey]) {
            mappedArr[elem[parentKey]].children.push(elem);
        } else {
            tree.push(mappedElem);
        }
    });

    return tree;
}

Example of usage:

createTree(yourListData, 'id', 'parentId');

If you mean how to check whether member variables have been initialized, you can do this by assigning them sentinel values in the constructor. Choose sentinel values as values that will never occur in normal usage of that variable. If a variables entire range is considered valid, you can create a boolean to indicate whether it has been initialized.

#include <limits>

class MyClass
{
    void SomeMethod();

    char mCharacter;
    bool isCharacterInitialized;
    double mDecimal;

    MyClass()
    : isCharacterInitialized(false)
    , mDecimal( std::numeric_limits<double>::quiet_NaN() )
    {}


};


void MyClass::SomeMethod()
{
    if ( isCharacterInitialized == false )
    {
        // do something with mCharacter.
    }

    if ( mDecimal != mDecimal ) // if true, mDecimal == NaN
    {
        // define mDecimal.
    }
}

this is just as a side note, but generally what you want to do is keep size on the Session and ViewState small. I generally just store IDs and small amounts of packets in Session and ViewState.

for instance if you want to pass large chunks of data from one page to another, you can store an ID in the querystring and use that ID to either get data from a database or a file.

PS: but like I said, this might be totally unrelated to your query :)

Yes to output { in string.Format you have to escape it like this {{

So this

String val = "1,2,3";
String.Format(" foo {{{0}}}", val);

will output "foo {1,2,3}".

BUT you have to know about a design bug in C# which is that by going on the above logic you would assume this below code will print {24.00}

int i = 24;
string str = String.Format("{{{0:N}}}", i); //gives '{N}' instead of {24.00}

But this prints {N}. This is because the way C# parses escape sequences and format characters. To get the desired value in the above case you have to use this instead.

String.Format("{0}{1:N}{2}", "{", i, "}") //evaluates to {24.00}

for example: $TargetDirectory = realpath(__DIR__."/../.."); //Will take you 2 folder's back

String realpath() :: Returns canonicalized absolute pathname ..

This combination (and values near to these) seems to "magically" work for me to keep the colorbar scaled to the plot, no matter what size the display.

plt.colorbar(im,fraction=0.046, pad=0.04)

It also does not require sharing the axis which can get the plot out of square.

you have to add the missing local lang helper: for me the missing ones where de_LU de_LU.UTF-8 . Mongo 2.6.4 worked wihtout mongo 2.6.5 throw an error on this

1 way to do that is

my.NEW.data.frame <- my.data.frame[-boxplot.stats(my.data.frame$my.column)$out, ]

or

my.high.value <- which(my.data.frame$age > 200 | my.data.frame$age < 0) 
my.NEW.data.frame <- my.data.frame[-my.high.value, ]

NOTICE: This is never a recommended use of git. This will overwrite changes on the remote. Only do this if you know 100% that your local changes should be pushed to the remote master.

Try this: git push -f origin master

Note the output while doing the merge - it is saying Fast Forward

In such situations, you want to do:

git merge v1.0 --no-commit --no-ff

I had the same challenge. This is the solution I found to add users to roles.

internal class Security
{
    ApplicationDbContext context = new ApplicationDbContext();

    internal void AddUserToRole(string userName, string roleName)
    {
        var UserManager = new UserManager<ApplicationUser>(new UserStore<ApplicationUser>(context));

        try
        {
            var user = UserManager.FindByName(userName);
            UserManager.AddToRole(user.Id, roleName);
            context.SaveChanges();
        }
        catch
        {
            throw;
        }
    }
}

To ensure full Unicode support and reversibility, consider using:

'\n'.codePointAt(0);

This will ensure that when testing characters over the UTF-16 limit, you will get their true code point value.

e.g.

''.codePointAt(0); // 68181
String.fromCodePoint(68181); // ''

''.charCodeAt(0);  // 55298
String.fromCharCode(55298);  // '?'

nginx also provides the $http_host variable which will pass the port for you. its a concatenation of host and port.

So u just need to do:

proxy_set_header Host $http_host;

Uninstallation :

sudo /Library/PostgreSQL/9.6/uninstall-postgresql.app/Contents/MacOS/installbuilder.sh

Removing the data file :

sudo rm -rf /Library/PostgreSQL

Removing the configs :

sudo rm /etc/postgres-reg.ini

And thats it.

You can use date to get time and date of a day:

[pengyu@GLaDOS ~]$date
Tue Aug 27 15:01:27 CST 2013

Also hwclock would do:

[pengyu@GLaDOS ~]$hwclock
Tue 27 Aug 2013 03:01:29 PM CST  -0.516080 seconds

For customized output, you can either redirect the output of date to something like awk, or write your own program to do that.

Remember to put your own executable scripts/binary into your PATH (e.g. /usr/bin) to make it invokable anywhere.

Try this:

int getYear(Date date1,Date date2){ 
      SimpleDateFormat simpleDateformat=new SimpleDateFormat("yyyy");
      Integer.parseInt(simpleDateformat.format(date1));

      return Integer.parseInt(simpleDateformat.format(date2))- Integer.parseInt(simpleDateformat.format(date1));

    }

Here is my solution:

arr = []
arr.append([1,2,3])
arr.append([4,5,6])
np_arr = np.array(arr)

To compile, you'll need NASM and LINK.EXE (from Visual studio Standard Edition)

   nasm -fwin32 hello.asm
   link /subsystem:console /nodefaultlib /entry:main hello.obj 

If you don't see a certain package, you can access to a full list of ports (also unnoficials, the packages you see on the web) launching the setup.exe with -k argument with value http://cygwinports.org/ports.gpg (example: C:\cygwin\setup\setup-x86.exe -K http://cygwinports.org/ports.gpg).

Doing so, you can choose a lot of extra packages, also extra versions of cURL (compat one). I do that to get Apache, cUrl, php5, php5-curl and some others :)

I don't know if apt-cyg can get those extra packages.

Try using this:

var x:Int!

var xTimesTwo:Int {
    get {
        return x * 2
    }
    set {
        x = newValue / 2
    }
}

This is basically Jack Wu's answer, but the difference is that in Jack Wu's answer his x variable is var x: Int, in mine, my x variable is like this: var x: Int!, so all I did was make it an optional type.

To expand on @Grgur's answer, if you look in your inspector, you'll find that using Link components gives them the preset color value color: -webkit-link. You'll need to override this along with the textDecoration if you don't want it to look like a default hyperlink.

In case that helps anybody I had the same issue with wampserver3.2.0_x64 on Windows 10 Enterprise.

Tried everything from the answers of this thread and nothing helped.

I then installed wampserver3.1.0_x86 instead and got the green light on first launch. I have no explanation but at least the desired end result.

You could remove your node_modules/ folder and then reinstall the dependencies from package.json.

rm -rf node_modules/
npm install

This would erase all installed packages in the current folder and only install the dependencies from package.json. If the dependencies have been previously installed npm will try to use the cached version, avoiding downloading the dependency a second time.

I think this sample explains the difference between the styles:

    element1 = "Hello"

    def __init__(self):
        self.element2 = "World"

obj = MyClass()

print dir(MyClass)
print "--"
print dir(obj)
print "--"
print obj.element1 
print obj.element2
print MyClass.element1 + " " + MyClass.element2
james@bodacious-wired:~$./test.py

--
Hello World
Hello
Traceback (most recent call last):
  File "./test.py", line 17, in <module>

AttributeError: class MyClass has no attribute 'element2'

element1 is bound to the class, element2 is bound to an instance of the class.

Use the oncontextmenu event.

Here's an example:

<div oncontextmenu="javascript:alert('success!');return false;">
    Lorem Ipsum
</div>

And using event listeners (credit to rampion from a comment in 2011):

el.addEventListener('contextmenu', function(ev) {
    ev.preventDefault();
    alert('success!');
    return false;
}, false);

Don't forget to return false, otherwise the standard context menu will still pop up.

If you are going to use a function you've written rather than javascript:alert("Success!"), remember to return false in BOTH the function AND the oncontextmenu attribute.

There is not such a proper way to download all the things all together from JSFiddle but there is a hack way to do just that. Simply add "embedded/" or "embedded/result/" at the end of your JSFiddle URL!, and then you can save the whole page as an HTML file + the external libraries (if you wants).

It can be opened using Visual Studio 2012.Follow the below path in VS after opening the project. View->Server Explorer->

>>> from datetime import date
>>>
>>> repr(date.today())        # calls date.today().__repr__()
'datetime.date(2009, 1, 16)'
>>> eval(_)                   # _ is the output of the last command
datetime.date(2009, 1, 16)

The output is a string that can be parsed by the python interpreter and results in an equal object.

If that's not possible, it should return a string in the form of <...some useful description...>.

SELECT * 
FROM TABLE_NAME
WHERE Date_Column >= DATEADD(MONTH, -3, GETDATE()) 

Mureinik's suggested method will return the same results, but doing it this way your query can benefit from any indexes on Date_Column.

or you can check against last 90 days.

SELECT * 
FROM TABLE_NAME
WHERE Date_Column >= DATEADD(DAY, -90, GETDATE()) 

Not my fiddle, but http://jsfiddle.net/maxisam/QrCXh/ shows the difference. The key piece is:

           scope:{
            /* NOTE: Normally I would set my attributes and bindings
            to be the same name but I wanted to delineate between 
            parent and isolated scope. */                
            isolatedAttributeFoo:'@attributeFoo',
            isolatedBindingFoo:'=bindingFoo',
            isolatedExpressionFoo:'&'
        }        

I realize I am biased as an old C programmer, but there are times when the various Python conventions make things hard to follow. I find the indent convention a bit of an annoyance at times.

Sometimes, clarity of when a statement or block ends is very useful. Standard C code will often read something like this:

for(i=0; i<100; i++) {
    do something here;
    do another thing here;
}

continue doing things;

where you use the whitespace for a lot of clarity - and it is easy to see where the loop ends.

Python does let you terminate with an (optional) semicolon. As noted above, that does NOT mean that there is a statement to execute followed by a 'null' statement. SO, for example,

print(x);
print(y);

Is the same as

print(x)
print(y)

If you believe that the first one has a null statement at the end of each line, try - as suggested - doing this:

print(x);;

It will throw a syntax error.

Personally, I find the semicolon to make code more readable when you have lots of nesting and functions with many arguments and/or long-named args. So, to my eye, this is a lot clearer than other choices:

if some_boolean_is_true:
    call_function(
        long_named_arg_1,
        long_named_arg_2,
        long_named_arg_3,
        long_named_arg_4
    );

since, to me, it lets you know that last ')' ends some 'block' that ran over many lines.

I personally think there is much to much made of PEP style guidelines, IDEs that enforce them, and the belief there is 'only one Pythonic way to do things'. If you believe the latter, go look at how to format numbers: as of now, Python supports four different ways to do it.

I am sure I will be flamed by some diehards, but the compiler/interpreter doesn't care if the arguments have long or short names, and - but for the indentation convention in Python - doesn't care about whitespace. The biggest problem with code is giving clarity to another human (and even yourself after months of work) to understand what is going on, where things start and end, etc.

The data from the request (content, inputs, files, querystring values) is all on this object HttpContext.Current.Request
To read the posted content

StreamReader reader = new StreamReader(HttpContext.Current.Request.InputStream);
string requestFromPost = reader.ReadToEnd();

To navigate through the all inputs

foreach (string key in HttpContext.Current.Request.Form.AllKeys)
{
   string value = HttpContext.Current.Request.Form[key];
}

Well, if you are aware of word embeddings like Glove/Word2Vec/Numberbatch, your job is half done. If not let me explain how this can be tackled. Convert each sentence into word tokens, and represent each of these tokens as vectors of high dimension (using the pre-trained word embeddings, or you could train them yourself even!). So, now you just don't capture their surface similarity but rather extract the meaning of each word which comprise the sentence as a whole. After this calculate their cosine similarity and you are set.

echo "<script>
alert('There are no fields to generate a report');

You were mixing up two different worlds.

Every action in gradle is a task, and so is test. And to exclude a task from gradle run, you can use the option --exclude-task or it's shorthand -x followed by the task name which needs to be excluded. Example:

gradle build -x test

The -x option should be repeated for all the tasks that needs to be excluded.

If you have different tasks for different type of tests in your build.gradle file, then you need to skip all those tasks that executes test. Say you have a task test which executes unit-tests and a task testFunctional which executes functional-tests. In this case, you can exclude all tests like below:

gradle build -x test -x testFunctional

In layman terms, (and probably the easiest way to attain a high level understanding of the problem)

Bubble sort is similar to standing in a line and trying to sort yourselves by height. You keep switching with the person next to you until you are at the right place. This takes place all the way from the left (or right depending on the implementation) and you keep switching until everybody is sorted.

In selection sort, however, what you are doing is similar to arranging a hand of cards. You look at the cards, take the smallest one, place it all the way to the left, and so on.

You can also use the PostAsJsonAsync() method available in HttpClient()

   var requestObj= JsonConvert.SerializeObject(obj);_x000D_
   HttpResponseMessage response = await    client.PostAsJsonAsync($"endpoint",requestObj).ConfigureAwait(false);

For people having a startTime (like 12h:30:30) and a duration (value in minutes like 120), you can guess the endTime like so:

const startTime = '12:30:00';
const durationInMinutes = '120';

const endTime = moment(startTime, 'HH:mm:ss').add(durationInMinutes, 'minutes').format('HH:mm');

// endTime is equal to "14:30"

You’d try from Anaconda Prompt.

You will see (base), now upgrade pip. Example:

(base) C:\>python -m pip install --upgrade pip
Requirement already up-to-date: pip in g:\anaconda3\lib\site-packages (20.0.2)

(base) C:\>pip -V
pip 20.0.2 from G:\Anaconda3\lib\site-packages\pip (python 3.7)

# Try install
(base) C:\>pip install selenium

This takes a longer time, but will also install or upgrade SSL libraries that Anaconda uses internally. Keep Going here

I like

if ('string'[/^str/]) ...

This is a hack. It will not work on all Python implementations distributions (in particular, those that do not have traceback.extract_stack.)

import traceback

def make_dict(*expr):
    (filename,line_number,function_name,text)=traceback.extract_stack()[-2]
    begin=text.find('make_dict(')+len('make_dict(')
    end=text.find(')',begin)
    text=[name.strip() for name in text[begin:end].split(',')]
    return dict(zip(text,expr))

bar=True
foo=False
print(make_dict(bar,foo))
# {'foo': False, 'bar': True}

Note that this hack is fragile:

make_dict(bar,
          foo)

(calling make_dict on 2 lines) will not work.

Instead of trying to generate the dict out of the values foo and bar, it would be much more Pythonic to generate the dict out of the string variable names 'foo' and 'bar':

dict([(name,locals()[name]) for name in ('foo','bar')])

Shorter version:

db.row_factory = lambda c, r: dict([(col[0], r[idx]) for idx, col in enumerate(c.description)])

There are other mechanisms to handle overflow than the simple minded linked list of overflow entries which e.g. wastes a lot of memory.

Which mechanism to use depends among other things on if you can choose the hash function and possible pick more than one (to implement e.g. double hashing to handle collisions); if you expect to often add items or if the map is static once filled; if you intend to remove items or not; ...

The best way to implement this is to first think about all these parameters and then not code it yourself but to pick a mature existing implementation. Google has a few good implementations -- e.g. http://code.google.com/p/google-sparsehash/

java.time

It’s about time someone provides the modern answer. The modern solution uses java.time, the modern Java date and time API. The classes SimpleDateFormat and Date used in the question and in a couple of the other answers are poorly designed and long outdated, the former in particular notoriously troublesome. TimeZone is poorly designed to. I recommend you avoid those.

    ZoneId utc = ZoneId.of("Etc/UTC");
    DateTimeFormatter targetFormatter = DateTimeFormatter.ofPattern(
            "MM/dd/yyyy hh:mm:ss a zzz", Locale.ENGLISH);

    String itsAlarmDttm = "2013-10-22T01:37:56";
    ZonedDateTime utcDateTime = LocalDateTime.parse(itsAlarmDttm)
            .atZone(ZoneId.systemDefault())
            .withZoneSameInstant(utc);
    String formatterUtcDateTime = utcDateTime.format(targetFormatter);
    System.out.println(formatterUtcDateTime);

When running in my time zone, Europe/Copenhagen, the output is:

10/21/2013 11:37:56 PM UTC

I have assumed that the string you got was in the default time zone of your JVM, a fragile assumption since that default setting can be changed at any time from another part of your program or another programming running in the same JVM. If you can, instead specify time zone explicitly, for example ZoneId.of("Europe/Podgorica") or ZoneId.of("Asia/Kolkata").

I am exploiting the fact that you string is in ISO 8601 format, the format the the modern classes parse as their default, that is, without any explicit formatter.

I am using a ZonedDateTime for the result date-time because it allows us to format it with UTC in the formatted string to eliminate any and all doubt. For other purposes one would typically have wanted an OffsetDateTime or an Instant instead.

Use:

$.ajax({
    url: 'feed/4', type: 'POST', data: "_METHOD=PUT&accessToken=63ce0fde", success: function(data) {
        console.log(data);
    }
});

Always remember to use _METHOD=PUT.

Here is a LINQ solution which is O(n) with decent constant factors:

int[] anArray = { 1, 5, 2, 7, 1 };

int index = 0;
int maxIndex = 0;

var max = anArray.Aggregate(
    (oldMax, element) => {
        ++index;
        if (element <= oldMax)
            return oldMax;
        maxIndex = index;
        return element;
    }
);

Console.WriteLine("max = {0}, maxIndex = {1}", max, maxIndex);

But you should really write an explicit for lop if you care about performance.

No, it's not the script, it's the fact that your script is not executed by Python at all. If your script is stored in a file named script.py, you have to execute it as python script.py, otherwise the default shell will execute it and it will bail out at the from keyword. (Incidentally, from is the name of a command line utility which prints names of those who have sent mail to the given username, so that's why it tries to access the mailboxes).

Another possibility is to add the following line to the top of the script:

#!/usr/bin/env python

This will instruct your shell to execute the script via python instead of trying to interpret it on its own.

From my experience and Maven best practices there are two kinds of "parent poms"

• "company" parent pom - this pom contains your company specific information and configuration that inherit every pom and doesn't need to be copied. These informations are:

  • repositories
  • distribution managment sections
  • common plugins configurations (like maven-compiler-plugin source and target versions)
  • organization, developers, etc

  Preparing this parent pom need to be done with caution, because all your company poms will inherit from it, so this pom have to be mature and stable (releasing a version of parent pom should not affect to release all your company projects!)

• second kind of parent pom is a multimodule parent. I prefer your first solution - this is a default maven convention for multi module projects, very often represents VCS code structure

The intention is to be scalable to a large scale build so should be scalable to a large number of projects and artifacts.

Mutliprojects have structure of trees - so you aren't arrown down to one level of parent pom. Try to find a suitable project struture for your needs - a classic exmample is how to disrtibute mutimodule projects

distibution/
documentation/
myproject/
  myproject-core/
  myproject-api/
  myproject-app/
  pom.xml
pom.xml

A few bonus questions:

• Where is the best place to define the various shared configuration as in source control, deployment directories, common plugins etc. (I'm assuming the parent but I've often been bitten by this and they've ended up in each project rather than a common one).

This configuration has to be wisely splitted into a "company" parent pom and project parent pom(s). Things related to all you project go to "company" parent and this related to current project go to project one's.

• How do the maven-release plugin, hudson and nexus deal with how you set up your multi-projects (possibly a giant question, it's more if anyone has been caught out when by how a multi-project build has been set up)?

Company parent pom have to be released first. For multiprojects standard rules applies. CI server need to know all to build the project correctly.

You don't need a CTE for this

sklearn.model_selection.train_test_split(*arrays, **options)[source]

Split arrays or matrices into random train and test subsets

Parameters: ... 
    random_state : int, RandomState instance or None, optional (default=None)

If int, random_state is the seed used by the random number generator; If RandomState instance, random_state is the random number generator; If None, the random number generator is the RandomState instance used by np.random. source: http://scikit-learn.org/stable/modules/generated/sklearn.model_selection.train_test_split.html

'''Regarding the random state, it is used in many randomized algorithms in sklearn to determine the random seed passed to the pseudo-random number generator. Therefore, it does not govern any aspect of the algorithm's behavior. As a consequence, random state values which performed well in the validation set do not correspond to those which would perform well in a new, unseen test set. Indeed, depending on the algorithm, you might see completely different results by just changing the ordering of training samples.''' source: https://stats.stackexchange.com/questions/263999/is-random-state-a-parameter-to-tune

Add more columns when you have variable loops that repeat at different rates. I'm not sure explicitly what you're trying to do, but I think I've done something that could apply.

Creating a single loop in Excel is prettty simple. It actually does the work for you. Try this on a new workbook

1. Enter "1" in A1
2. Enter "=A1+1" in A2

A3 will automatically be "=A2+1" as you drag down. The first steps don't have to be that explicit. Excel will automatically recognize the pattern and count if you just put "2" in A2, but if we want B1-B5 to be "100" and B5-B10 to be "200" (counting up the same way) you can see why knowing how to do it explicitly matters. In this scenario, You just enter:

3. "100" in B1, drag through to B5 and
4. "=B1+100" in B6

B7 will automatically be "=B2+100" etc. as you drag down, so basically it increases every 5 rows infinitely. To make a loop of numbers 1-5 in column A:

5. Enter "=A1" in cell A6. As you drag down, it will automatically be "=A2" in cell A7, etc. because of the way that Excel does things.

So, now we have column A repeating numbers 1-5 while column B is increasing by 100 every 5 cells.You could make column B repeat, for instance, the numbers 100-900 in using the same method as you did with column A as a way to produce, for instance, each possible combination with multiple variables. Drag down the columns and they'll do it infinitely. I'm not explicitly addressing the scenario given, but if you follow the steps and understand them, the concept should give you an answer to the problem that involves adding more columns and concactinating or using them as your variables.

as a general way of working with Fragments, as JafarKhQ noted, you should not pass the params in the constructor but with a Bundle.

the built-in method for that in the Fragment class is setArguments(Bundle) and getArguments().

basically, what you do is set up a bundle with all your Parcelable items and send them on.
in turn, your Fragment will get those items in it's onCreate and do it's magic to them.

the way shown in the DialogFragment link was one way of doing this in a multi appearing fragment with one specific type of data and works fine most of the time, but you can also do this manually.

I've gone through these posts and somehow ended up finding a simple answer, which I'm posting here for those how want short and sweet solutions:

1. Use console.log("Hello World") in your script.
2. Go to https://script.google.com/home/my and select your add-on.
3. Click on the ellipsis menu on Project Details, select Executions.

4. Click on the header of the latest execution and read the log.

This Bash script helped me out:

#!/bin/bash
for branch in $(git branch --all | grep '^\s*remotes' | egrep --invert-match '(:?HEAD|master)$'); do
    git branch --track "${branch##*/}" "$branch"
done

It will create tracking branches for all remote branches, except master (which you probably got from the original clone command). I think you might still need to do a

git fetch --all
git pull --all

to be sure.

One liner: git branch -a | grep -v HEAD | perl -ne 'chomp($_); s|^\*?\s*||; if (m|(.+)/(.+)| && not $d{$2}) {print qq(git branch --track $2 $1/$2\n)} else {$d{$_}=1}' | csh -xfs
As usual: test in your setup before copying rm -rf universe as we know it

You don't need to pass the quotes enclosing the custom headers to curl. Also, your variables in the middle of the data argument should be quoted.

First, write a function that generates the post data of your script. This saves you from all sort of headaches concerning shell quoting and makes it easier to read an maintain the script than feeding the post data on curl's invocation line as in your attempt:

generate_post_data()
{
  cat <<EOF
{
  "account": {
    "email": "$email",
    "screenName": "$screenName",
    "type": "$theType",
    "passwordSettings": {
      "password": "$password",
      "passwordConfirm": "$password"
    }
  },
  "firstName": "$firstName",
  "lastName": "$lastName",
  "middleName": "$middleName",
  "locale": "$locale",
  "registrationSiteId": "$registrationSiteId",
  "receiveEmail": "$receiveEmail",
  "dateOfBirth": "$dob",
  "mobileNumber": "$mobileNumber",
  "gender": "$gender",
  "fuelActivationDate": "$fuelActivationDate",
  "postalCode": "$postalCode",
  "country": "$country",
  "city": "$city",
  "state": "$state",
  "bio": "$bio",
  "jpFirstNameKana": "$jpFirstNameKana",
  "jpLastNameKana": "$jpLastNameKana",
  "height": "$height",
  "weight": "$weight",
  "distanceUnit": "MILES",
  "weightUnit": "POUNDS",
  "heightUnit": "FT/INCHES"
}
EOF
}

It is then easy to use that function in the invocation of curl:

curl -i \
-H "Accept: application/json" \
-H "Content-Type:application/json" \
-X POST --data "$(generate_post_data)" "https://xxx:[email protected]/xxxxx/xxxx/xxxx"

This said, here are a few clarifications about shell quoting rules:

The double quotes in the -H arguments (as in -H "foo bar") tell bash to keep what's inside as a single argument (even if it contains spaces).

The single quotes in the --data argument (as in --data 'foo bar') do the same, except they pass all text verbatim (including double quote characters and the dollar sign).

To insert a variable in the middle of a single quoted text, you have to end the single quote, then concatenate with the double quoted variable, and re-open the single quote to continue the text: 'foo bar'"$variable"'more foo'.

Both answers are valid, but don't forget to initializate the value of the variable, by default is NULL and with T-SQL:

NULL + "Any text" => NULL

It's a very common mistake, don't forget it!

Also is good idea to use ISNULL function:

SELECT @result = @result + ISNULL(StudentId + ',', '') FROM Student

I don't like adding new package into my project just to handle this simple task.

And also, I try my best to avoid RECURSIVE algorithm.... since, for most cases it is slower compared to non Recursive one.

So I made a function to get all the folder content (and its sub folder).... NON-Recursively

var getDirectoryContent = function(dirPath) {
    /* 
        get list of files and directories from given dirPath and all it's sub directories
        NON RECURSIVE ALGORITHM
        By. Dreamsavior
    */
    var RESULT = {'files':[], 'dirs':[]};

    var fs = fs||require('fs');
    if (Boolean(dirPath) == false) {
        return RESULT;
    }
    if (fs.existsSync(dirPath) == false) {
        console.warn("Path does not exist : ", dirPath);
        return RESULT;
    }

    var directoryList = []
    var DIRECTORY_SEPARATOR = "\\";
    if (dirPath[dirPath.length -1] !== DIRECTORY_SEPARATOR) dirPath = dirPath+DIRECTORY_SEPARATOR;

    directoryList.push(dirPath); // initial

    while (directoryList.length > 0) {
        var thisDir  = directoryList.shift(); 
        if (Boolean(fs.existsSync(thisDir) && fs.lstatSync(thisDir).isDirectory()) == false) continue;

        var thisDirContent = fs.readdirSync(thisDir);
        while (thisDirContent.length > 0) { 
            var thisFile  = thisDirContent.shift(); 
            var objPath = thisDir+thisFile

            if (fs.existsSync(objPath) == false) continue;
            if (fs.lstatSync(objPath).isDirectory()) { // is a directory
                let thisDirPath = objPath+DIRECTORY_SEPARATOR; 
                directoryList.push(thisDirPath);
                RESULT['dirs'].push(thisDirPath);

            } else  { // is a file
                RESULT['files'].push(objPath); 

            } 
        } 

    }
    return RESULT;
}

the only drawback of this function is that this is Synchronous function... You have been warned ;)

I just wanted to add this version because this is such a useful thread and I think this is a very simple implementation. I have used this multiple times in various types if multithreaded application:

 Task.Factory.StartNew(() =>
      {
        DoLongRunningWork();
        Application.Current.Dispatcher.BeginInvoke(DispatcherPriority.Normal, new Action(() =>
              { txt.Text = "Complete"; }));
      });

Mac already has Python and a package manager called easy_install, so open Terminal and type

sudo easy_install selenium

For my web application i corrected my mistake by writing

instead of : http://localhost:11472/authorize/
type :      http://localhost/authorize/
