Referring to the answer of jnml, you could prevent new instances of Base type by not exporting the Base type at all (i.e. write it lowercase). If needed, you may make an exportable interface that has a method that returns a base type. This interface could be used in functions from the outside that deal with Bases, i.e.

package a

type base int

const (
    A base = iota
    C
    T
    G
)


type Baser interface {
    Base() base
}

// every base must fulfill the Baser interface
func(b base) Base() base {
    return b
}


func(b base) OtherMethod()  {
}

package main

import "a"

// func from the outside that handles a.base via a.Baser
// since a.base is not exported, only exported bases that are created within package a may be used, like a.A, a.C, a.T. and a.G
func HandleBasers(b a.Baser) {
    base := b.Base()
    base.OtherMethod()
}


// func from the outside that returns a.A or a.C, depending of condition
func AorC(condition bool) a.Baser {
    if condition {
       return a.A
    }
    return a.C
}

Inside the main package a.Baser is effectively like an enum now. Only inside the a package you may define new instances.

JavaScript does not have such declarations. It would be:

var cubes = ...

regardless

But you can do:

for(var i = 0; i < cubes.length; i++)
{
  for(var j = 0; j < cubes[i].length; j++)
  {

  }
}

Note that JavaScript allows jagged arrays, like:

[
  [1, 2, 3],
  [1, 2, 3, 4]
]

since arrays can contain any type of object, including an array of arbitrary length.

As noted by MDC:

"for..in should not be used to iterate over an Array where index order is important"

If you use your original syntax, there is no guarantee the elements will be visited in numeric order.

Here's a Javascript implementation of @Stochastically's Java implementation for anyone needing it:

class GPSKalmanFilter {
  constructor (decay = 3) {
    this.decay = decay
    this.variance = -1
    this.minAccuracy = 1
  }

  process (lat, lng, accuracy, timestampInMs) {
    if (accuracy < this.minAccuracy) accuracy = this.minAccuracy

    if (this.variance < 0) {
      this.timestampInMs = timestampInMs
      this.lat = lat
      this.lng = lng
      this.variance = accuracy * accuracy
    } else {
      const timeIncMs = timestampInMs - this.timestampInMs

      if (timeIncMs > 0) {
        this.variance += (timeIncMs * this.decay * this.decay) / 1000
        this.timestampInMs = timestampInMs
      }

      const _k = this.variance / (this.variance + (accuracy * accuracy))
      this.lat += _k * (lat - this.lat)
      this.lng += _k * (lng - this.lng)

      this.variance = (1 - _k) * this.variance
    }

    return [this.lng, this.lat]
  }
}

Usage example:

   const kalmanFilter = new GPSKalmanFilter()
   const updatedCoords = []

    for (let index = 0; index < coords.length; index++) {
      const { lat, lng, accuracy, timestampInMs } = coords[index]
      updatedCoords[index] = kalmanFilter.process(lat, lng, accuracy, timestampInMs)
    }

No need to apologize for asking a question! Try using the RIGHT function. It returns the last n characters of a string.

=RIGHT(A1, 1)

Download whatever configuration script that your browser is using.

the script would have various host:port configuration. based on the domain you want to connect , one of the host:port is selected by the borwser.

in the eclipse network setting you can try to put on of the host ports and see if that works.

worked for me.

the config script looks like,

if (isPlainHostName(host))
    return "DIRECT";
else if (dnsDomainIs(host, "<***sample host name *******>"))
    return "PROXY ***some ip*****; DIRECT";
else if (dnsDomainIs(host, "address.com")
        || dnsDomainIs(host, "adress2..com")
        || dnsDomainIs(host, "address3.com")
        || dnsDomainIs(host, "address4.com")        
    return "PROXY <***some proxyhost****>:8080";

you would need to look for the host port in the return statement.

You can use Target-specific Variable Values. Example:

CXXFLAGS = -g3 -gdwarf2
CCFLAGS = -g3 -gdwarf2

all: executable

debug: CXXFLAGS += -DDEBUG -g
debug: CCFLAGS += -DDEBUG -g
debug: executable

executable: CommandParser.tab.o CommandParser.yy.o Command.o
    $(CXX) -o output CommandParser.yy.o CommandParser.tab.o Command.o -lfl

CommandParser.yy.o: CommandParser.l 
    flex -o CommandParser.yy.c CommandParser.l
    $(CC) -c CommandParser.yy.c

Remember to use $(CXX) or $(CC) in all your compile commands.

Then, 'make debug' will have extra flags like -DDEBUG and -g where as 'make' will not.

On a side note, you can make your Makefile a lot more concise like other posts had suggested.

Primary keys are for uniquely identifying rows. This is done by comparing all parts of a key to the input.

Per definition, NULL cannot be part of a successful comparison. Even a comparison to itself (NULL = NULL) will fail. This means a key containing NULL would not work.

Additonally, NULL is allowed in a foreign key, to mark an optional relationship.^(*) Allowing it in the PK as well would break this.

^(*)A word of caution: Having nullable foreign keys is not clean relational database design.

If there are two entities A and B where A can optionally be related to B, the clean solution is to create a resolution table (let's say AB). That table would link A with B: If there is a relationship then it would contain a record, if there isn't then it would not.

jQuery(document).ready(function () {
        jQuery('.select-all').on('change', function () {
            if (jQuery(this).is(':checked')) {
                jQuery('input.class-name').each(function () {
                    this.checked = true;
                });
            } else {
                jQuery('input.class-name').each(function () {
                    this.checked = false;
                });
            }
        });
    });

First of all you should get JdK 8.

if you have Jdk installed.

you should set its path using cmd prompt or system variables.

sometimes it can happen that the path is not set due to which eclipse is unable to get the properties for jdk.

Installing latest ecipse luna can solve your problem.

i have indigo and luna. i can set 1.8 in luna but 1.7 in indigo.Eclipse luna

You can check the eclipse site. it says that the eclipse luna was certainly to associate the properties for jdk 8.

When the first characters in a script are #!, that is called the shebang. If your file starts with #!/path/to/something the standard is to run something and pass the rest of the file to that program as an input.

With that said, the difference between #!/bin/bash, #!/bin/sh, or even #!/bin/zsh is whether the bash, sh, or zsh programs are used to interpret the rest of the file. bash and sh are just different programs, traditionally. On some Linux systems they are two copies of the same program. On other Linux systems, sh is a link to dash, and on traditional Unix systems (Solaris, Irix, etc) bash is usually a completely different program from sh.

Of course, the rest of the line doesn't have to end in sh. It could just as well be #!/usr/bin/python, #!/usr/bin/perl, or even #!/usr/local/bin/my_own_scripting_language.

If you are asking whether there is a built in Pythonic range-like function, there isn't. You have to do it the brute force way. Maybe rangy would be of interest to you.

The more recent tidyverse way is to use the mutate_at function:

library(tidyverse)
library(magrittr)
set.seed(88)

data <- data.frame(matrix(sample(1:40), 4, 10, dimnames = list(1:4, LETTERS[1:10])))
cols <- c("A", "C", "D", "H")

data %<>% mutate_at(cols, funs(factor(.)))
str(data)
 $ A: Factor w/ 4 levels "5","17","18",..: 2 1 4 3   
 $ B: int  36 35 2 26
 $ C: Factor w/ 4 levels "22","31","32",..: 1 2 4 3
 $ D: Factor w/ 4 levels "1","9","16","39": 3 4 1 2
 $ E: int  3 14 30 38
 $ F: int  27 15 28 37
 $ G: int  19 11 6 21
 $ H: Factor w/ 4 levels "7","12","20",..: 1 3 4 2
 $ I: int  23 24 13 8
 $ J: int  10 25 4 33

function setEqualHeight(columns) {
  var tallestColumn = 0;

  columns.each(function(){
    var currentHeight = $(this).height();

    if(currentHeight > tallestColumn){
      tallestColumn  = currentHeight;
    }
  });

  columns.height(tallestColumn);
}

=> setEqualHeight($('.column'));

In cases where you do not have access to the derived class source, but need all the source of the derived class besides the current method, then I would recommended you should also do a derived class and call the implementation of the derived class.

Here is an example:

//No access to the source of the following classes
public class Base
{
     public virtual void method1(){ Console.WriteLine("In Base");}
}
public class Derived : Base
{
     public override void method1(){ Console.WriteLine("In Derived");}
     public void method2(){ Console.WriteLine("Some important method in Derived");}
}

//Here should go your classes
//First do your own derived class
public class MyDerived : Base
{         
}

//Then derive from the derived class 
//and call the bass class implementation via your derived class
public class specialDerived : Derived
{
     public override void method1()
     { 
          MyDerived md = new MyDerived();
          //This is actually the base.base class implementation
          MyDerived.method1();  
     }         
}

You can use querySelectorAll:

document.querySelectorAll('[data-foo]');

When you work with unsigned types, modular arithmetic (also known as "wrap around" behavior) is taking place. To understand this modular arithmetic, just have a look at these clocks:

9 + 4 = 1 (13 mod 12), so to the other direction it is: 1 - 4 = 9 (-3 mod 12). The same principle is applied while working with unsigned types. If the result type is unsigned, then modular arithmetic takes place.

Now look at the following operations storing the result as an unsigned int:

unsigned int five = 5, seven = 7;
unsigned int a = five - seven;      // a = (-2 % 2^32) = 4294967294 

int one = 1, six = 6;
unsigned int b = one - six;         // b = (-5 % 2^32) = 4294967291

When you want to make sure that the result is signed, then stored it into signed variable or cast it to signed. When you want to get the difference between numbers and make sure that the modular arithmetic will not be applied, then you should consider using abs() function defined in stdlib.h:

int c = five - seven;       // c = -2
int d = abs(five - seven);  // d =  2

Be very careful, especially while writing conditions, because:

if (abs(five - seven) < seven)  // = if (2 < 7)
    // ...

if (five - seven < -1)          // = if (-2 < -1)
    // ...

if (one - six < 1)              // = if (-5 < 1)
    // ...

if ((int)(five - seven) < 1)    // = if (-2 < 1)
    // ...

but

if (five - seven < 1)   // = if ((unsigned int)-2 < 1) = if (4294967294 < 1)
    // ...

if (one - six < five)   // = if ((unsigned int)-5 < 5) = if (4294967291 < 5)
    // ...

Ok, finally found the solution.

Probably due to lack of experience with ReactJS and web development...

    var Task = React.createClass({
    render: function() {
      var percentage = this.props.children + '%';
      ....
        <div className="ui-progressbar-value ui-widget-header ui-corner-left" style={{width : percentage}}/>
      ...

I created the percentage variable outside in the render function.

break is used to exit (escape) the for-loop, while-loop, switch-statement that you are currently executing.

return will exit the entire method you are currently executing (and possibly return a value to the caller, optional).

So to answer your question (as others have noted in comments and answers) you cannot use either break nor return to escape an if-else-statement per se. They are used to escape other scopes.

Consider the following example. The value of x inside the while-loop will determine if the code below the loop will be executed or not:

void f()
{
   int x = -1;
   while(true)
   {
     if(x == 0)
        break;         // escape while() and jump to execute code after the the loop 
     else if(x == 1)
        return;        // will end the function f() immediately,
                       // no further code inside this method will be executed.

     do stuff and eventually set variable x to either 0 or 1
     ...
   }

   code that will be executed on break (but not with return).
   ....
}

The more easy way its by executing the next command:

ls -ls /usr/bin/python*

Output look like this:

/usr/bin/python           /usr/bin/python2.7        /usr/bin/pythonw
/usr/bin/python-config    /usr/bin/python2.7-config /usr/bin/pythonw2.7

For Symfony 3.4

Check the constant in this file vendor/symfony/http-kernel/Kernel.php

const VERSION = '3.4.3';

OR

composer show | grep symfony/http-kernel

On 32-bit machine sizeof pointer is 32 bits ( 4 bytes), while on 64 bit machine it's 8 byte. Regardless of what data type they are pointing to, they have fixed size.

If you are using Hibernate its not possible to create an Entity without a primary key. This issues can create problem if you are working with an existing database which was created with plain sql/ddl scripts, and no primary key was added

LOL, a super lame hack, but at least curl and firefox accepts it:

while true ; do (dd if=/dev/zero count=10000;echo -e "HTTP/1.1\n\n $(date)") | nc -l  1500  ; done

You better replace it soon with something proper!

Ah yes, my nc were not exactly the same as yours, it did not like the -p option.

Here's an easy function you can use to get it. I used axios to make the API request, but you can use anything else.

async function getCountry(lat, long) {
  const { data: { results } } = await axios.get(`https://maps.googleapis.com/maps/api/geocode/json?latlng=${lat},${long}&key=${GOOGLE_API_KEY}`);
  const { address_components } = results[0];

  for (let i = 0; i < address_components.length; i++) {
    const { types, long_name } = address_components[i];

    if (types.indexOf("country") !== -1) return long_name;
  }
}

You need to publish the exposed ports by using the following options:

-P (upper case) or --publish-all that will tell Docker to use random ports from your host and map them to the exposed container's ports.

-p (lower case) or --publish=[] that will tell Docker to use ports you manually set and map them to the exposed container's ports.

The second option is preferred because you already know which ports are mapped. If you use the first option then you will need to call docker inspect demo and check which random ports are being used from your host at the Ports section.

Just run the following command:

docker run -it -p 8080:8080 demo

After that your url will work.

^ used at the beginning of a character range, or negative lookahead/lookbehind assertions.

If you have been given a database file and have not installed the correct server (either SQLite or MySQL), try this tool: https://dbconvert.com/sqlite/mysql/ The trial version allows converting the first 50 records of each table, the rest of the data is watermarked. This is a Windows program, and can either dump into a running database server, or can dump output to a .sql file

Quick fix. Create whole structure tr > td > button; then find button inside; attach event on it; end filtering of chain and at the and insert it into dom.

$("#myButton").click(function () {
    var test = $('<tr><td><button>Test</button></td></tr>').find('button').click(function () {
        alert('hi');
    }).end();

    $("#nodeAttributeHeader").attr('style', 'display: table-row;');
    $("#addNodeTable tr:last").before(test);
});

It exists, but it's hard to search for. I think most people call it the "splat" operator.

It's in the documentation as "Unpacking argument lists".

You'd use it like this: foo(*values). There's also one for dictionaries:

d = {'a': 1, 'b': 2}
def foo(a, b):
    pass
foo(**d)

The subject of the certificate is the entity its public key is associated with (i.e. the "owner" of the certificate).

As RFC 5280 says:

The subject field identifies the entity associated with the public key stored in the subject public key field. The subject name MAY be carried in the subject field and/or the subjectAltName extension.

X.509 certificates have a Subject (Distinguished Name) field and can also have multiple names in the Subject Alternative Name extension.

The Subject DN is made of multiple relative distinguished names (RDNs) (themselves made of attribute assertion values) such as "CN=yourname" or "O=yourorganization".

In the context of the article you're linking to, the subject would be the user/owner of the cert.

The 2nd parameter of http.post is the body of the message, ie the payload and not the url search parameters. Pass data in that parameter.

From the documentation

post(url: string, body: any, options?: RequestOptionsArgs) : Observable<Response>

public post(cmd: string, data: object): Observable<any> {

    const params = new URLSearchParams();
    params.set('cmd', cmd);

    const options = new RequestOptions({
      headers: this.getAuthorizedHeaders(),
      responseType: ResponseContentType.Json,
      params: params,
      withCredentials: false
    });

    console.log('Options: ' + JSON.stringify(options));

    return this.http.post(this.BASE_URL, data, options)
      .map(this.handleData)
      .catch(this.handleError);
  }

Edit

You should also check out the 1st parameter (BASE_URL). It must contain the complete url (minus query string) that you want to reach. I mention in due to the name you gave it and I can only guess what the value currently is (maybe just the domain?).

Also there is no need to call JSON.stringify on the data/payload that is sent in the http body.

If you still can't reach your end point look in the browser's network activity in the development console to see what is being sent. You can then further determine if the correct end point is being called wit the correct header and body. If it appears that is correct then use POSTMAN or Fiddler or something similar to see if you can hit your endpoint that way (outside of Angular).

10 weeks? Apparently you can do it in 24 hours!

http://www.amazon.com/Sams-Teach-Yourself-Programming-Hours/dp/0672328445

EDIT:

Okay, so only 1 person found my answer amusing, but not amusing enough to upvote. The real question is how good do you need to be in 10 weeks?

If you get yourself a good book (the one linked above has some good reviews on Amazon), then in 10 weeks you might be proficient enough to do something useful in Java, but it takes years to become expert. Any time spent between 10 weeks and several years will move you from beginner towards expert.

Oh and read Teach Yourself Programming in Ten Years.

Dirk's answer is a great one. If you want an appearance like what hist produces, you can also try this:

buckets <- c(0,1,2,3,4,5,25)
mydata_hist <- hist(mydata$V3, breaks=buckets, plot=FALSE)
bp <- barplot(mydata_hist$count, log="y", col="white", names.arg=buckets)
text(bp, mydata_hist$counts, labels=mydata_hist$counts, pos=1)

The last line is optional, it adds value labels just under the top of each bar. This can be useful for log scale graphs, but can also be omitted.

I also pass main, xlab, and ylab parameters to provide a plot title, x-axis label, and y-axis label.

If you have LWP installed, it provides a binary simply named "GET".

wget -O-, curl, and lynx -source behave similarly.

Consider Android Development:

IDE: Eclipse etc..

Library: android.app.Activity library (Class with all code)

API: Interface basically all functions with which we call

SDK: The Android SDK provides you the API libraries and developer tools necessary to build, test, and debug apps for Android (----tools - DDMS,Emulator ----platforms - Android OS versions, ----platform-tools - ADB, ----API docs)

ToolKit: Could be ADT Bundle

Framework: Big library but more of architecture-oriented

I think we can improve the best answer a little bit, I'm using:

len = sum(1 for _ in reader)

Moreover, we shouldnt forget pythonic code not always have the best performance in the project. In example: If we can do more operations at the same time in the same data set Its better to do all in the same bucle instead make two or more pythonic bucles.

If you want to scroll down to bottom of infinite page (like linkedin.com), you can use this code:

SCROLL_PAUSE_TIME = 0.5

# Get scroll height
last_height = driver.execute_script("return document.body.scrollHeight")

while True:
    # Scroll down to bottom
    driver.execute_script("window.scrollTo(0, document.body.scrollHeight);")

    # Wait to load page
    time.sleep(SCROLL_PAUSE_TIME)

    # Calculate new scroll height and compare with last scroll height
    new_height = driver.execute_script("return document.body.scrollHeight")
    if new_height == last_height:
        break
    last_height = new_height

use Contains of jquery Contains like this

if ($('.type:contains("> <")').length > 0)

There is no tuple type in Go, and you are correct, the multiple values returned by functions do not represent a first-class object.

Nick's answer shows how you can do something similar that handles arbitrary types using interface{}. (I might have used an array rather than a struct to make it indexable like a tuple, but the key idea is the interface{} type)

My other answer shows how you can do something similar that avoids creating a type using anonymous structs.

These techniques have some properties of tuples, but no, they are not tuples.

I recommend PowerGrep

I had to do an e-discovery project several years ago. I found that fisdstr had some limitations, most especially fisdstr would eventually fail

the script had to search across thousands of files using a couple of dozen search terms/phrases.

Cygwin's grep worked much better, it didn't choke often, but ultimately I went to PowerGrep because the graphical interface made it much easier to tell when and where it crashed, and also it was really easy to edit in all the conditionals and output that I wanted. Ultimately PowerGrep was the most reliable of the three.

Other answers already on Stackoverflow:

• How do I install modules locally without root access...
• How can I use a new Perl module without install permissions?

From perlfaq8:

When you build modules, tell Perl where to install the modules.

For Makefile.PL-based distributions, use the INSTALL_BASE option when generating Makefiles:

perl Makefile.PL INSTALL_BASE=/mydir/perl

You can set this in your CPAN.pm configuration so modules automatically install in your private library directory when you use the CPAN.pm shell:

% cpan
cpan> o conf makepl_arg INSTALL_BASE=/mydir/perl
cpan> o conf commit

For Build.PL-based distributions, use the --install_base option:

perl Build.PL --install_base /mydir/perl

You can configure CPAN.pm to automatically use this option too:

% cpan

I didn't find any of the mentioned options to be correct or work for me when I came to this page. They did give me ideas to test things out and I found that this worked for me.

dontGoToLink(e) {
  e.preventDefault();
 }

render() {
  return (<a href="test.com" onClick={this.dontGoToLink} />});
}

The below packages are also helps you,

yum install gcc glibc glibc-common gd gd-devel -y

CMake takes a CMakeList file, and outputs it to a platform-specific build format, e.g. a Makefile, Visual Studio, etc.

You run CMake on the CMakeList first. If you're on Visual Studio, you can then load the output project/solution.

Basically indexOf() is a method belongs to string(array object also), But while calling the function you are passing a number, try to cast it to a string and pass it.

document.getElementById("oset").innerHTML = timeD2C(timeofday + "");

 var timeofday = new Date().getHours() + (new Date().getMinutes()) / 60;_x000D_
_x000D_
_x000D_
_x000D_
_x000D_
 function timeD2C(time) { // Converts 11.5 (decimal) to 11:30 (colon)_x000D_
    var pos = time.indexOf('.');_x000D_
    var hrs = time.substr(1, pos - 1);_x000D_
    var min = (time.substr(pos, 2)) * 60;_x000D_
_x000D_
    if (hrs > 11) {_x000D_
        hrs = (hrs - 12) + ":" + min + " PM";_x000D_
    } else {_x000D_
        hrs += ":" + min + " AM";_x000D_
    }_x000D_
    return hrs;_x000D_
}_x000D_
alert(timeD2C(timeofday+""));

And it is good to do the string conversion inside your function definition,

function timeD2C(time) { 
  time = time + "";
  var pos = time.indexOf('.');

So that the code flow won't break at times when devs forget to pass a string into this function.

If you know the location of installed jboss folder then simply open it and look for version.txt file.

You could try this via SSH: rm -rf foldernamehere

var settings = new JsonSerializerSettings();
settings.ContractResolver = new CamelCasePropertyNamesContractResolver();
settings.NullValueHandling = NullValueHandling.Ignore;

You don't need to specify PropertyConfigurator.configure("log4j.properties"); in your Log4J class, If you have already defined the log4j.properties in your project structure.

In case of Web Dynamic Project: -

You need to save your log4j.properties under WebContent -> WEB-INF -> log4j.properties

I hope this may help you.

Simple rules of bidirectional relationships:

1.For many-to-one bidirectional relationships, the many side is always the owning side of the relationship. Example: 1 Room has many Person (a Person belongs one Room only) -> owning side is Person

2.For one-to-one bidirectional relationships, the owning side corresponds to the side that contains the corresponding foreign key.

3.For many-to-many bidirectional relationships, either side may be the owning side.

Hope can help you.

I had the same error when I imported web requests from fiddler captured sessions to Visual Studio webtests. Some POST requests did not have a StringHttpBody tag. I added an empty one to them and the error was gone. Add this after the Headers tag:

    <StringHttpBody ContentType="" InsertByteOrderMark="False">
  </StringHttpBody>

You can run below commands. I believe this is what you want!

Note: Make sure the port 8080 is open. If not, kill the process that is using 8080 port using sudo kill -9 $(sudo lsof -t -i:8080)

 ./catalina.sh run

Default Rpi resolution is : 1366x768 if i'm not mistaken.

You can change it though.

Hope it helps.

For a VB or C# app, one way to do this is by using Office Interop. This depends on which version of Excel you're working with.

For Excel 2003, this MSDN article is a good place to start. Understanding the Excel Object Model from a Visual Studio 2005 Developer's Perspective

You'll basically need to do the following:

• Start the Excel application.
• Open the Excel workbook.
• Retrieve the worksheet from the workbook by name or index.
• Iterate through all the Cells in the worksheet which were retrieved as a range.
• Sample (untested) code excerpt below for the last step.

    Excel.Range allCellsRng;
    string lowerRightCell = "IV65536";
    allCellsRng = ws.get_Range("A1", lowerRightCell).Cells;
    foreach (Range cell in allCellsRng)
    {
        if (null == cell.Value2 || isBlank(cell.Value2))
        {
          // Do something.
        }
        else if (isText(cell.Value2))
        {
          // Do something.
        }
        else if (isNumeric(cell.Value2))
        {
          // Do something.
        }
    }

For Excel 2007, try this MSDN reference.

I am using in the way and it is working for me.

public static void main(String[] args) {
    new CarpoolDBAppTest();

}

public CarpoolDBAppTest(){
    ApplicationContext context = new ClassPathXmlApplicationContext("application-context.xml");
    Student stud = (Student) context.getBean("yourBeanId");
}

Here Student is my classm you will get the class matching yourBeanId.

Now work on that object with whatever operation you want to do.

This was a fun question! Another way to handle this for variable length lists is to build a function that takes full advantage of the .format method and list unpacking. In the following example I don't use any fancy formatting, but that can easily be changed to suit your needs.

list_1 = [1,2,3,4,5,6]
list_2 = [1,2,3,4,5,6,7,8]

# Create a function that can apply formatting to lists of any length:
def ListToFormattedString(alist):
    # Create a format spec for each item in the input `alist`.
    # E.g., each item will be right-adjusted, field width=3.
    format_list = ['{:>3}' for item in alist] 

    # Now join the format specs into a single string:
    # E.g., '{:>3}, {:>3}, {:>3}' if the input list has 3 items.
    s = ','.join(format_list)

    # Now unpack the input list `alist` into the format string. Done!
    return s.format(*alist)

# Example output:
>>>ListToFormattedString(list_1)
'  1,  2,  3,  4,  5,  6'
>>>ListToFormattedString(list_2)
'  1,  2,  3,  4,  5,  6,  7,  8'

Use:

#include <windows.h>

Sleep(sometime_in_millisecs); // Note uppercase S

And here's a small example that compiles with MinGW and does what it says on the tin:

#include <windows.h>
#include <stdio.h>

int main() {
    printf( "starting to sleep...\n" );
    Sleep(3000); // Sleep three seconds
    printf("sleep ended\n");
}

to pass many options you can pass a object to a @Input decorator with custom data in a single line.

In the template

<li *ngFor = 'let opt of currentQuestion.options' 
                [selectable] = 'opt'
                [myOptions] ="{first: opt.val1, second: opt.val2}" // these are your multiple parameters
                (selectedOption) = 'onOptionSelection($event)' >
     {{opt.option}}
</li>

so in Directive class

@Directive({
  selector: '[selectable]'
})

export class SelectableDirective{
  private el: HTMLElement;
  @Input('selectable') option:any;
  @Input('myOptions') data;

  //do something with data.first
  ...
  // do something with data.second
}

import urllib, urllib2, cookielib

username = 'myuser'
password = 'mypassword'

cj = cookielib.CookieJar()
opener = urllib2.build_opener(urllib2.HTTPCookieProcessor(cj))
login_data = urllib.urlencode({'username' : username, 'j_password' : password})
opener.open('http://www.example.com/login.php', login_data)
resp = opener.open('http://www.example.com/hiddenpage.php')
print resp.read()

resp.read() is the straight html of the page you want to open, and you can use opener to view any page using your session cookie.

irb(main)> varA
=> {0=>["12", "34", "35", "231"]}
irb(main)> varA = Hash[*ex.collect{|a,b| [a,b.join(",")]}.flatten]
...

You can also have a look at the method findText(const QString & text) from QComboBox; it returns the index of the element which contains the given text, (-1 if not found). The advantage of using this method is that you don't need to set the second parameter when you add an item.

Here is a little example :

/* Create the comboBox */
QComboBox   *_comboBox = new QComboBox;

/* Create the ComboBox elements list (here we use QString) */
QList<QString> stringsList;
stringsList.append("Text1");
stringsList.append("Text3");
stringsList.append("Text4");
stringsList.append("Text2");
stringsList.append("Text5");

/* Populate the comboBox */
_comboBox->addItems(stringsList);

/* Create the label */
QLabel *label = new QLabel;

/* Search for "Text2" text */
int index = _comboBox->findText("Text2");
if( index == -1 )
    label->setText("Text2 not found !");
else
    label->setText(QString("Text2's index is ")
                   .append(QString::number(_comboBox->findText("Text2"))));

/* setup layout */
QVBoxLayout *layout = new QVBoxLayout(this);
layout->addWidget(_comboBox);
layout->addWidget(label);

SELECT datname FROM pg_database WHERE datistemplate = false

#for postgres

You can use the Copy method in the System.IO.File class.

The answers provided above are absolutely correct and worth to read but I just wanted to give a straight forward answer to the question.

The question asked is just a type conversion question and here its conversion from int data type to float data type and for that you can do it by the function :

float()

And for more details you can visit this page.

Here's a snippet which I wrote which performs the same functionality.

This code is similar to the one written by Kunal Wadhwa.

char *dynamicCharString()
{
char *str, c;
int i;
str = (char*)malloc(1*sizeof(char));

while(c = getc(stdin),c!='\n')
{
    str[i] = c;
    i++;
    realloc(str,i*sizeof(char));
}
str[i] = '\0';
return str;
}

Use the following JavaScript to get the value after hash (#) from a URL. You don't need to use jQuery for that.

var hash = location.hash.substr(1);

I have got this code and tutorial from here - How to get hash value from URL using JavaScript

It may be useful package list-to-tree Install:

bower install list-to-tree --save

or

npm install list-to-tree --save

For example, have list:

var list = [
  {
    id: 1,
    parent: 0
  }, {
    id: 2,
    parent: 1
  }, {
    id: 3,
    parent: 1
  }, {
    id: 4,
    parent: 2
  }, {
    id: 5,
    parent: 2
  }, {
    id: 6,
    parent: 0
  }, {
    id: 7,
    parent: 0
  }, {
    id: 8,
    parent: 7
  }, {
    id: 9,
    parent: 8
  }, {
    id: 10,
    parent: 0
  }
];

Use package list-to-tree:

var ltt = new LTT(list, {
  key_id: 'id',
  key_parent: 'parent'
});
var tree = ltt.GetTree();

Result:

[{
  "id": 1,
  "parent": 0,
  "child": [
    {
      "id": 2,
      "parent": 1,
      "child": [
        {
          "id": 4,
          "parent": 2
        }, {
          "id": 5, "parent": 2
        }
      ]
    },
    {
      "id": 3,
      "parent": 1
    }
  ]
}, {
  "id": 6,
  "parent": 0
}, {
  "id": 7,
  "parent": 0,
  "child": [
    {
      "id": 8,
      "parent": 7,
      "child": [
        {
          "id": 9,
          "parent": 8
        }
      ]
    }
  ]
}, {
  "id": 10,
  "parent": 0
}];

You could use remove(). More information on jQuery remove().

$(this).children("ul").remove();

Note that this will remove all ul elements that are children.

The only time I have experienced this was when the MVC framework was not installed on the server. Could that be the case?

A missing Pages section in Views\Web.config could also be at fault.

    private int GetSync()
    {
        try
        {
            ManualResetEvent mre = new ManualResetEvent(false);
            int result = null;

            Parallel.Invoke(async () =>
            {
                result = await SomeCalcAsync(5+5);
                mre.Set();
            });

            mre.WaitOne();
            return result;
        }
        catch (Exception)
        {
            return null;
        }
    }

Classes are not meant to be just collections of methods. A class is supposed to represent an abstract concept, with both state (fields) and behaviour (methods) which changes the state. Using inheritance just to get some desired behaviour sounds like bad OO design, and exactly the reason why many languages disallow multiple inheritance: in order to prevent "spaghetti inheritance", i.e. extending 3 classes because each has a method you need, and ending up with a class that inherits 100 method and 20 fields, yet only ever uses 5 of them.

You can easily make lists of lists

list1 <- list(a = 2, b = 3)
list2 <- list(c = "a", d = "b")
mylist <- list(list1, list2)

mylist is now a list that contains two lists. To access list1 you can use mylist[[1]]. If you want to be able to something like mylist$list1 then you need to do somethingl like

mylist <- list(list1 = list1, list2 = list2)
# Now you can do the following
mylist$list1

Edit: To reply to your edit. Just use double bracket indexing

a <- list_all[[1]]
a[[1]]
#[1] 1
a[[2]]
#[1] 2

export https_proxy=http://user:pswd@host:port
                   ^^^^

Use http for https_proxy instead of https

you need to open the connection using connection.open() on the SqlCommand.Connection object before executing ExecuteNonQuery()

OAuth is all about delegating Authorization (choosing someone who can do Authorization for you). Note that Authentication and Authorization are different things. OAuth is Authorization (Access control), and if you want to implement Authentication (ID verification) also, OpenID protocol can be used on top of OAuth.

All big companies like Facebook, Google, Github,... use this kind of authentication/authorization nowadays. For example, I just signed in on this website using my Google account, this means Stackoverflow doesn't know my password, it receives the allowance from Google where my password (hashed obviously) is saved. This gives a lot of benefits, one of them is; In the near future you won't have to make several accounts on every website. One website (which you trust most) can be used to login to all other websites. So you'll only have to remember one password.

If you are working with Android's MediaStore database, here is how to store an image and then display it after it is saved.

on button click write this

 Intent in = new Intent(Intent.ACTION_PICK,
                    android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
            in.putExtra("crop", "true");
            in.putExtra("outputX", 100);
            in.putExtra("outputY", 100);
            in.putExtra("scale", true);
            in.putExtra("return-data", true);

            startActivityForResult(in, 1);

then do this in your activity

@Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        // TODO Auto-generated method stub
        super.onActivityResult(requestCode, resultCode, data);

        if (requestCode == 1 && resultCode == RESULT_OK && data != null) {

            Bitmap bmp = (Bitmap) data.getExtras().get("data");

            img.setImageBitmap(bmp);
            btnadd.requestFocus();

            ByteArrayOutputStream baos = new ByteArrayOutputStream();
            bmp.compress(Bitmap.CompressFormat.JPEG, 100, baos);
            byte[] b = baos.toByteArray();
            String encodedImageString = Base64.encodeToString(b, Base64.DEFAULT);

            byte[] bytarray = Base64.decode(encodedImageString, Base64.DEFAULT);
            Bitmap bmimage = BitmapFactory.decodeByteArray(bytarray, 0,
                    bytarray.length);

        }

    }

Create a class in your CSS file:

.active {
  z-index: 20;
  background: rgb(23,55,94)
  color: #fff;
}

Then in your jQuery

$(this).addClass("active");

Not sure this was around when this question was asked but:

df.describe().show("columnName")

gives mean, count, stdtev stats on a column. I think it returns on all columns if you just do .show()

There are lots of great answers here, particularly @oma's. But one other thing you could try is to use custom column serialization. If you don't mind everything being stored lowercase in your db then you could create:

# lib/serializers/downcasing_string_serializer.rb
module Serializers
  class DowncasingStringSerializer
    def self.load(value)
      value
    end

    def self.dump(value)
      value.downcase
    end
  end
end

Then in your model:

# app/models/my_model.rb
serialize :name, Serializers::DowncasingStringSerializer
validates_uniqueness_of :name, :case_sensitive => false

The benefit of this approach is that you can still use all the regular finders (including find_or_create_by) without using custom scopes, functions, or having lower(name) = ? in your queries.

The downside is that you lose casing information in the database.

Enter "#!/bin/sh" before script. Then save it as script.sh for example. copy it to $HOME/bin or $HOME/usr/bin
The directory can be different on different linux distros but they end with 'bin' and are in home directory cd $HOME/bin or $HOME/usr/bin
Type chmod 700 script.sh
And you can run it just by typing run.sh on terminal. If it not work, try chmod +x run.sh instead of chmod 700 run.sh

try apt-file. It is difficult to remember the package name where the missing file resides. It is generic and useful for any package files.

For example:

root@ubuntu234:~/auto# apt-file search --regexp '/Python.h$'
pypy-dev: /usr/lib/pypy/include/Python.h
python2.7-dbg: /usr/include/python2.7_d/Python.h
python2.7-dev: /usr/include/python2.7/Python.h
python3.2-dbg: /usr/include/python3.2dmu/Python.h
python3.2-dev: /usr/include/python3.2mu/Python.h
root@ubuntu234:~/auto# 

Now you can make an expert guess as to which one to choose from.

1. For MySQL:

SELECT FIND_IN_SET(5, columnname) AS result 
FROM table

2.For Postgres SQL :

SELECT * 
FROM TABLENAME f
WHERE 'searchvalue' = ANY (string_to_array(COLUMNNAME, ','))

Example

select * 
from customer f
where '11' = ANY (string_to_array(customerids, ','))

In your onCreateView method, container is actually a ViewPager instance.

So, just calling

ViewPager vpViewPager = (ViewPager) container;
vpViewPager.setCurrentItem(1);

will change current fragment in your ViewPager.

The only visible result I was able to understand was first to connect with the user I wanted to get the rights, then with the following query:

SELECT GRANTEE, PRIVILEGE, TABLE_NAME FROM USER_TAB_PRIVS;

If you do overflow:hidden then keep in mind that it will also hide the comment box that comes up in XFBML version... after user likes it. So best if you do this...

/* make the like button smaller */
.fb_edge_widget_with_comment iframe
{
    width:47px !important;
}

/* but make the span that holds the comment box larger */
span.fb_edge_comment_widget.fb_iframe_widget iframe
{
    width:401px !important;
}

it depends on your php settings...
use phpinfo() and take a look at the session chapter. There are values like session.gc_maxlifetime and session.cache_expire and session.cookie_lifetime which affects the sessions lifetime

EDIT: it's like Martin write before

this code works for me name it cmd.bat

@echo off
title This is Only A Test
echo.
:Loop
set /p the="%cd%"
%the%
echo.
goto loop

Here is a good table for printf specifiers. So it should be %hu for unsigned short int.

And link to Wikipedia "C data types" too.

For me the issue was caused by config file automatically genearted by importing the WSDL. I updated the binding to from basicHttpBinding to customBinding. Adding additional exception handling did not help pointing this out.

Before

<basicHttpBinding>
            <binding name="ServiceName">
                <security mode="Transport" />
            </binding>
        </basicHttpBinding>`

After

<customBinding>
        <binding name="ServiceName">
          <textMessageEncoding messageVersion="Soap12" />
          <httpsTransport />
        </binding>
      </customBinding>`

Your printf needs a format string:

printf("%d\n", x);

This reference page gives details on how to use printf and related functions.

if you have numbers in list, you can use map to apply str to each element:

print ', '.join(map(str, LIST))

^ map is C code so it's faster than str(i) for i in LIST

Just had a similar problem, except i needed a NodeList and not a Document, here's what I came up with. It's mostly the same solution as before, augmented to get the root element down as a NodeList and using erickson's suggestion of using an InputSource instead for character encoding issues.

private String DOC_ROOT="root";
String xml=getXmlString();
Document xmlDoc=loadXMLFrom(xml);
Element template=xmlDoc.getDocumentElement();
NodeList nodes=xmlDoc.getElementsByTagName(DOC_ROOT);

public static Document loadXMLFrom(String xml) throws Exception {
        InputSource is= new InputSource(new StringReader(xml));
        DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
        factory.setNamespaceAware(true);
        DocumentBuilder builder = null;
        builder = factory.newDocumentBuilder();
        Document doc = builder.parse(is);
        return doc;
    }

Call SYS_CONTEXT to get the current schema. From Ask Tom "How to get current schema:

select sys_context( 'userenv', 'current_schema' ) from dual;

My solution

ALTER TABLE `table_name` MODIFY COLUMN `column_name` TIMESTAMP NOT
NULL DEFAULT CURRENT_TIMESTAMP;

If you want your anchor to still appear to be clickable:

$("a").removeAttr("href").css("cursor","pointer");

And if you wanted to remove the href from only anchors with certain attributes (eg ones that just have a hash mark as the href - this can be useful in asp.net)

$("a[href='#']").removeAttr("href").css("cursor","pointer");

I started using the AngiesList.Redis.RedisSessionStateModule, which aside from using the (very fast) Redis server for storage (I'm using the windows port -- though there is also an MSOpenTech port), it does absolutely no locking on the session.

In my opinion, if your application is structured in a reasonable way, this is not a problem. If you actually need locked, consistent data as part of the session, you should specifically implement a lock/concurrency check on your own.

MS deciding that every ASP.NET session should be locked by default just to handle poor application design is a bad decision, in my opinion. Especially because it seems like most developers didn't/don't even realize sessions were locked, let alone that apps apparently need to be structured so you can do read-only session state as much as possible (opt-out, where possible).

Do it in simple. According to documentation https://developer.android.com/training/data-storage/files

String imageName = "IMG_" + String.valueOf(System.currentTimeMillis()) +".jpg";
        picFile = new File(ProfileActivity.this.getCacheDir(),imageName);

and delete it after usage

picFile.delete()

In postgresql you can use regular expressions in WHERE clause. Check http://www.postgresql.org/docs/8.4/static/functions-matching.html

MySQL has something simmilar: http://dev.mysql.com/doc/refman/5.5/en/regexp.html

Simply use

java.util.Collections.sort(list)

without String.CASE_INSENSITIVE_ORDER comparator parameter.

You could store this into a temporary table.

So instead of doing the CTE/sub query you would use a temp table.

Good article on these here http://codingsight.com/introduction-to-temporary-tables-in-sql-server/

If you are simply looking for the occurrence of "Miami" or "Florida" inside a string (since you put * at both ends), it's probably better to use the InStr function instead of Like. Not only are the results more predictable, but I believe you'll get better performance.

Also, VBA is not short-circuited so when you use the AND keyword, it will test both sides of the AND, regardless if the first test failed or not. In VBA, it is more optimal to use 2 if-statements in these cases, that way you aren't checking for "Florida" if you don't find "Miami".

The other advice I have is that a for-each loop is faster than a for-loop. Using .offset, you can achieve the same thing, but with better effeciency. Of course there are even better ways (like variant arrays), but those will add a layer of complexity not needed in this example.

Here is some sample code:

Sub test()

Application.ScreenUpdating = False
Dim lastRow As Long
Dim cell As Range
lastRow = Range("A" & Rows.Count).End(xlUp).Row

For Each cell In Range("A1:A" & lastRow)
    If InStr(1, cell.Value, "Miami") <> 0 Then
        If InStr(1, cell.Offset(, 3).Value, "Florida") <> 0 Then
            cell.Offset(, 2).Value = "BA"
        End If
    End If
Next

Application.ScreenUpdating = True
End Sub

I hope you find some of this helpful, and keep at it with VBA! ^^

MFMailComposeViewController is the way to go after the release of iPhone OS 3.0 software. You can look at the sample code or the tutorial I wrote.

After trying few answers they are either not related to my project or , I have tried cleaning and rebuilding (https://stackoverflow.com/a/48760966/8463813). But it didn't work for me directly. I have compared it with older version of code, in which i observed some library files(jars and aars in External Libraries directory) are missing. Tried Invalidate Cache and Restart worked, which created all the libraries and working fine.

You can use this snippet to validate 16 digits card numbers with the Luhn algorithm:

function validateCardNumber(number) {
    var regex = new RegExp("^[0-9]{16}$");
    if (!regex.test(number))
        return false;

    return luhnCheck(number);
}

function luhnCheck(val) {
    var sum = 0;
    for (var i = 0; i < val.length; i++) {
        var intVal = parseInt(val.substr(i, 1));
        if (i % 2 == 0) {
            intVal *= 2;
            if (intVal > 9) {
                intVal = 1 + (intVal % 10);
            }
        }
        sum += intVal;
    }
    return (sum % 10) == 0;
}

I had the same issue and it appears that the Node.js version was the problem.

I installed the previous version of Node.js (10.14.2) and everything was ok using nvm (allow you to install several version of Node.js and quickly switch from a version to another).

It is not a "clean" solution, but it can serve you temporarly.

Your code doesn't work for binary files because they can't be cast to strings in the data event handler. If you need to manipulate binary files you'll need to use a buffer. Sorry, I do not have an example of using a buffer because in my case I needed to manipulate HTML files. I just check the content type and then for text/html files update them as needed:

app.get('/*', function(clientRequest, clientResponse) {
  var options = { 
    hostname: 'google.com',
    port: 80, 
    path: clientRequest.url,
    method: 'GET'
  };  

  var googleRequest = http.request(options, function(googleResponse) { 
    var body = ''; 

    if (String(googleResponse.headers['content-type']).indexOf('text/html') !== -1) {
      googleResponse.on('data', function(chunk) {
        body += chunk;
      }); 

      googleResponse.on('end', function() {
        // Make changes to HTML files when they're done being read.
        body = body.replace(/google.com/gi, host + ':' + port);
        body = body.replace(
          /<\/body>/, 
          '<script src="http://localhost:3000/new-script.js" type="text/javascript"></script></body>'
        );

        clientResponse.writeHead(googleResponse.statusCode, googleResponse.headers);
        clientResponse.end(body);
      }); 
    }   
    else {
      googleResponse.pipe(clientResponse, {
        end: true
      }); 
    }   
  }); 

  googleRequest.end();
});    

Remove stop words from the text file using Python

print('====THIS IS HOW TO REMOVE STOP WORS====')

with open('one.txt','r')as myFile:

    str1=myFile.read()

    stop_words ="not", "is", "it", "By","between","This","By","A","when","And","up","Then","was","by","It","If","can","an","he","This","or","And","a","i","it","am","at","on","in","of","to","is","so","too","my","the","and","but","are","very","here","even","from","them","then","than","this","that","though","be","But","these"

    myList=[]

    myList.extend(str1.split(" "))

    for i in myList:

        if i not in stop_words:

            print ("____________")

            print(i,end='\n')

You don't need to use an indexer (since it a bit less typesafe). You have two options :

interface EnumServiceItem {
    id: number; label: string; key: any
}

interface EnumServiceItems extends Array<EnumServiceItem>{}


// Option A 
var result: EnumServiceItem[] = [
    { id: 0, label: 'CId', key: 'contentId' },
    { id: 1, label: 'Modified By', key: 'modifiedBy' },
    { id: 2, label: 'Modified Date', key: 'modified' },
    { id: 3, label: 'Status', key: 'contentStatusId' },
    { id: 4, label: 'Status > Type', key: ['contentStatusId', 'contentTypeId'] },
    { id: 5, label: 'Title', key: 'title' },
    { id: 6, label: 'Type', key: 'contentTypeId' },
    { id: 7, label: 'Type > Status', key: ['contentTypeId', 'contentStatusId'] }
];

// Option B
var result: EnumServiceItems = [
    { id: 0, label: 'CId', key: 'contentId' },
    { id: 1, label: 'Modified By', key: 'modifiedBy' },
    { id: 2, label: 'Modified Date', key: 'modified' },
    { id: 3, label: 'Status', key: 'contentStatusId' },
    { id: 4, label: 'Status > Type', key: ['contentStatusId', 'contentTypeId'] },
    { id: 5, label: 'Title', key: 'title' },
    { id: 6, label: 'Type', key: 'contentTypeId' },
    { id: 7, label: 'Type > Status', key: ['contentTypeId', 'contentStatusId'] }
]

Personally I recommend Option A (simpler migration when you are using classes not interfaces).

Add the css:

   html,body{
        height:100%;
        }
    .bg-img {
        background: url(image.jpg) no-repeat center top; 
        background-size: cover; 
        height:100%;     
    }

And html is:

<div class="bg-mg"></div>

CSS: stretching background image to 100% width and height of screen?

sometime you missed some file like I missed my one file rt.java so better to check yours .........

C:\Program Files\Java\jdk1.8.0_112\jre\lib

#include <stdio.h>
#include <string.h>

int main()
{
    char string[] = "Strlwr in C";

    printf("%s\n",strlwr(string));

    return  0;
}

use strlwr for lowering the case

With an already-set origin master, you just have to use the below command -

git pull "https://github.com/yourUserName/yourRepo.git"

Generally, this is a missing package problem, just place the caret at the unresolved reference and press Alt+Enter to reveal the options, then you should know how to solve it.

brew install cask
brew cask install xquartz
brew tap homebrew/science
brew install r

This way, everything is packager managed, so there's no need to manually download and install anything.

What's about similar approach, but without boxing to the Long objects:

File[] files = directory.listFiles();

Arrays.sort(files, new Comparator<File>() {
    public int compare(File f1, File f2) {
        return Long.compare(f1.lastModified(), f2.lastModified());
    }
});

Most probably it has to do with caching on the device. Catching the exception and ignoring is not nice but my problem was fixed and it seems to work.

A WAR (Web Archive) is a module that gets loaded into a Web container of a Java Application Server. A Java Application Server has two containers (runtime environments) - one is a Web container and the other is a EJB container.

The Web container hosts Web applications based on JSP or the Servlets API - designed specifically for web request handling - so more of a request/response style of distributed computing. A Web container requires the Web module to be packaged as a WAR file - that is a special JAR file with a web.xml file in the WEB-INF folder.

An EJB container hosts Enterprise java beans based on the EJB API designed to provide extended business functionality such as declarative transactions, declarative method level security and multiprotocol support - so more of an RPC style of distributed computing. EJB containers require EJB modules to be packaged as JAR files - these have an ejb-jar.xml file in the META-INF folder.

Enterprise applications may consist of one or more modules that can either be Web modules (packaged as a WAR file), EJB modules (packaged as a JAR file), or both of them. Enterprise applications are packaged as EAR files - these are special JAR files containing an application.xml file in the META-INF folder.

Basically, EAR files are a superset containing WAR files and JAR files. Java Application Servers allow deployment of standalone web modules in a WAR file, though internally, they create EAR files as a wrapper around WAR files. Standalone web containers such as Tomcat and Jetty do not support EAR files - these are not full-fledged Application servers. Web applications in these containers are to be deployed as WAR files only.

In application servers, EAR files contain configurations such as application security role mapping, EJB reference mapping and context root URL mapping of web modules.

Apart from Web modules and EJB modules, EAR files can also contain connector modules packaged as RAR files and Client modules packaged as JAR files.

I have tried this query in SQL Server and this worked for me :

SELECT name FROM sys.columns WHERE OBJECT_ID = OBJECT_ID('table_name')

No, Bootstrap doesn't have a class for that, but this kind of class is considered a "utility" class, similar to the ".pull-right" class that @anton mentioned.

If you look at utilities.less you will see very few utility classes in Bootstrap, the reason being that this kind of class is generally frowned upon, and is recommended to be used for either: a) prototyping and development - so you can quickly build out your pages, then remove the pull-right and pull-left classes in favor of applying floats to more semantic classes or to the elements themselves, or b) when it's clearly more practical than a more semantic solution.

In your case, by your question it looks like you wish to have certain text align on the right in your table, but not all of it. Semantically, it would be better to do something like (I'm just going to make up a few classes here, except for the default bootstrap class, .table):

  <table class="table price-table">
    <thead>
      <th class="price-label">Total</th>
    </thead>
    <tbody>
      <tr>
        <td class="price-value">$1,000,000.00</td>
      </tr>
    </tbody>
  </table>

And just apply the text-align: left or text-align: right declarations to the price-value and price-label classes (or whatever classes work for you).

The problem with applying align-right as a class, is that if you want to refactor your tables you will have to redo the markup and the styles. If you use semantic classes you might be able to get away with refactoring only the CSS content. Plus, if are taking the time to apply a class to an element, it's best practice to try to assign semantic value to that class so that the markup is easier to navigate for other programmers (or you three months later).

One way to think of it is this: when you pose the question "What is this td for?", you will not get clarification from the answer "align-right".

Another way of finding out your key information is to go to your java folder, for me it was at

C:\Program Files\Java\jdk1.8.0_60\bin

and run the following command

keytool -list -v -keystore "%USERPROFILE%\.android\debug.keystore" -alias androiddebugkey -storepass android -keypass android

from the command you can easily see that keystore address is "c:\users/<%mylogin%>.android\debug.keystore" , alias is "androiddebugkey" store password is "android" key password is "android"

This is the default configuration from the Android 'Get API Key' documentation. https://developers.google.com/maps/documentation/android-api/signup

Leaving this answer here for others who ran into my situation.

My codeigniter app was working fine in localhost/WAMP, but was unable to route and produced 404 not found errors when pushing to an AWS EC2 instance. My issue was solved from the answer from HERE htaccess works in localhost but doesn't work in EC2 instance

(route to my admin page) {domain}/admin was producing 404

the /etc/httpd/conf/httpd.conf file needs to be modified.

-after every instance of "DocumentRoot "/var/www/html"" (2 places) "AllowOverride None" needed to be changed to "AllowOverride All".

Restarted the EC2 instance from the AWS dashboard.

{domain}/admin is now accessible and working as intended.

hope this helps someone else like it helped me!

Due to https://mywiki.wooledge.org/BashPitfalls#Non-atomic_writes_with_xargs_-P (output from parallel jobs in xargs risks being mixed), I would use GNU Parallel instead of xargs to parallelize:

cat url.lst |
  parallel -P0 -q curl -o /dev/null --silent --head --write-out '%{url_effective}: %{http_code}\n' > outfile

In this particular case it may be safe to use xargs because the output is so short, so the problem with using xargs is rather that if someone later changes the code to do something bigger, it will no longer be safe. Or if someone reads this question and thinks he can replace curl with something else, then that may also not be safe.

Use USE. This will enable you to select the database.

USE photogallery;

12.8.4: USE Syntax

You can also specify the database you want when connecting:

$ mysql -u user -p photogallery

In my case updating buildToolsVersion in app level build.gradle worked perfectly. If you don't know which to use you can create new project and copy buildToolsVersion from that into existing one.

This should give you the current date minus 1 year:

select now() - interval '1 year';

I picked up the content using JavaScript and created a window that I could print in stead...

In iOS6, Apple supports this via the <input type="file"> tag. I couldn't find a useful link in Apple's developer documentation, but there's an example here.

It looks like overlays and more advanced functionality is not yet available, but this should work for a lot of use cases.

EDIT: The w3c has a spec that iOS6 Safari seems to implement a subset of. The capture attribute is notably missing.

I also had the same issue. I've fixed it by using the following code.

        <Button Width="30" Margin="0,5" HorizontalAlignment="Stretch"  Click="OnSearch" >
            <DockPanel>
                <Image Source="../Resources/Back.jpg"/>
            </DockPanel>
        </Button>

Note: Make sure the build action of the image in the property window, should be Resource.

There are multiple nuget packages read in the following order:

1. First the NuGetDefaults.Config file. You will find this in %ProgramFiles(x86)%\NuGet\Config.
2. The computer-level file.
3. The user-level file. You will find this in %APPDATA%\NuGet\nuget.config.
4. Any file named nuget.config beginning from the root of your drive up to the directory where nuget.exe is called.
5. The config file you specify in the -configfile option when calling nuget.exe

You can find more information here.

As defined in App_start.BundleConfig, it's just calling

bundles.Add(new StyleBundle("~/Content/css").Include("~/Content/site.css"));

Nothing happens even if you remove that section.

As the error message states, the method used to get the F score is from the "Classification" part of sklearn - thus the talking about "labels".

Do you have a regression problem? Sklearn provides a "F score" method for regression under the "feature selection" group: http://scikit-learn.org/stable/modules/generated/sklearn.feature_selection.f_regression.html

In case you do have a classification problem, @Shovalt's answer seems correct to me.

I found that place to put the redirect complent of react-router is in the method render, but if you want to redirect after some validation, by example, the best way to redirect is using the old reliable, window.location.href, i.e.:

evalSuccessResponse(data){
   if(data.code===200){
    window.location.href = urlOneSignHome;
   }else{
     //TODO Something
   }    
}

When you are programming React Native never will need to go outside of the app, and the mechanism to open another app is completely different.

Summary (@Freek Wiekmeijer, @gtalarico) other's answer:

Logic of Login

• Many resource(pages, api) need authentication, then can access, otherwise 405 Not Allowed
• Common authentication=grant access method are:
  • cookie
  • auth header
    • Basic xxx
    • Authorization xxx

How use cookie in requests to auth

1. first get/generate cookie
2. send cookie for following request

• manual set cookie in headers
• auto process cookie by requests's
  • session to auto manage cookies
  • response.cookies to manually set cookies

use requests's session auto manage cookies

curSession = requests.Session() 
# all cookies received will be stored in the session object

payload={'username': "yourName",'password': "yourPassword"}
curSession.post(firstUrl, data=payload)
# internally return your expected cookies, can use for following auth

# internally use previously generated cookies, can access the resources
curSession.get(secondUrl)

curSession.get(thirdUrl)

manually control requests's response.cookies

payload={'username': "yourName",'password': "yourPassword"}
resp1 = requests.post(firstUrl, data=payload)

# manually pass previously returned cookies into following request
resp2 = requests.get(secondUrl, cookies= resp1.cookies)

resp3 = requests.get(thirdUrl, cookies= resp2.cookies)

I would do it this way:

UPDATE YourTable SET B = COALESCE(B, A);

COALESCE is a function that returns its first non-null argument.

In this example, if B on a given row is not null, the update is a no-op.

If B is null, the COALESCE skips it and uses A instead.

I've had good success with the asyncproc module, which deals nicely with the output from the processes. For example:

import os
from asynproc import Process
myProc = Process("myprogram.app")

while True:
    # check to see if process has ended
    poll = myProc.wait(os.WNOHANG)
    if poll is not None:
        break
    # print any new output
    out = myProc.read()
    if out != "":
        print out

geonames.org has an api and a data dump of worldwide geographical places.

If you download the 64 bit version of Eclipse; it will look for the 64 bit version of JRE. If you download the 32 bit version of Eclipse; it will look for the 32 bit version of JRE

What I did was to install the both the 32 and 64 bit version of JRE. You can get that from the SUN Oracle site. The JAVA site seems to automatically install the 32 bit version of Java. I guess that's because of the web browser.

Some awk version.

awk '/19:55/{c=5} c-->0'
awk '/19:55/{c=5} c && c--'

When pattern found, set c=5
If c is true, print and decrease number of c

Address already in use means that the port you are trying to allocate for your current execution is already occupied/allocated to some other process.

If you are a developer and if you are working on an application which require lots of testing, you might have an instance of your same application running in background (may be you forgot to stop it properly)

So if you encounter this error, just see which application/process is using the port.

In linux try using netstat -tulpn. This command will list down a process list with all running processes.

Check if an application is using your port. If that application or process is another important one then you might want to use another port which is not used by any process/application.

Anyway you can stop the process which uses your port and let your application take it.

If you are in linux environment try,

• Use netstat -tulpn to display the processes
• kill <pid> This will terminate the process

If you are using windows,

• Use netstat -a -o -n to check for the port usages
• Use taskkill /F /PID <pid> to kill that process

A bit too late but I got the same issue and fixed it switching schemalocation into schemaLocation in the persistence.xml file (line 1).

Another way to do this would to first get row indices, append extra copies of the df, and then order by the indices:

df$index = 1:nrow(df)
df = rbind(df,df)
df = df[order(df$index),][,-ncol(df)]

Although the other solutions may be shorter, this method may be more advantageous in certain situations.

This should work, I just tested it out and it worked as expected: no expansion, substitution, or what-have-you took place.

cat <<< '
#!/bin/bash
curr=`cat /sys/class/backlight/intel_backlight/actual_brightness`
if [ $curr -lt 4477 ]; then
  curr=$((curr+406));
  echo $curr  > /sys/class/backlight/intel_backlight/brightness;
fi' > file # use overwrite mode so that you don't keep on appending the same script to that file over and over again, unless that's what you want. 

Using the following also works.

cat <<< ' > file
 ... code ...'

Also, it's worth noting that when using heredocs, such as << EOF, substitution and variable expansion and the like takes place. So doing something like this:

cat << EOF > file
cd "$HOME"
echo "$PWD" # echo the current path
EOF

will always result in the expansion of the variables $HOME and $PWD. So if your home directory is /home/foobar and the current path is /home/foobar/bin, file will look like this:

cd "/home/foobar"
echo "/home/foobar/bin"

instead of the expected:

cd "$HOME"
echo "$PWD"

numpy.random.randint accepts a third argument (size) , in which you can specify the size of the output array. You can use this to create your DataFrame -

df = pd.DataFrame(np.random.randint(0,100,size=(100, 4)), columns=list('ABCD'))

Here - np.random.randint(0,100,size=(100, 4)) - creates an output array of size (100,4) with random integer elements between [0,100) .

Demo -

import numpy as np
import pandas as pd
df = pd.DataFrame(np.random.randint(0,100,size=(100, 4)), columns=list('ABCD'))

which produces:

     A   B   C   D
0   45  88  44  92
1   62  34   2  86
2   85  65  11  31
3   74  43  42  56
4   90  38  34  93
5    0  94  45  10
6   58  23  23  60
..  ..  ..  ..  ..

If you want to delete the index of array:

Use array_name.pop(index_no.)

ex:-

>>> arr = [1,2,3,4]
>>> arr.pop(2)
>>>arr
[1,2,4]

If you want to delete a particular string/element from the array then

>>> arr1 = ['python3.6' , 'python2' ,'python3']
>>> arr1.remove('python2')
>>> arr1
['python3.6','python3']

Here is a small extension for accessing keys and values in dictionary by index:

extension Dictionary {
    subscript(i: Int) -> (key: Key, value: Value) {
        return self[index(startIndex, offsetBy: i)]
    }
}

For Kotlin you can Try this.

var builder = NotificationCompat.Builder(this,CHANNEL_ID)
     .setVibrate(longArrayOf(1000, 1000, 1000, 1000, 1000))
     .setSound(Settings.System.DEFAULT_NOTIFICATION_URI)

I think sometimes stupid mistakes can give us this error.

<div id="#main"> <--- id with hashtag
    <div id="mainActivity" v-component="{{currentActivity}}" class="activity"></div>
</div>

To

<div id="main"> <--- id without hashtag
    <div id="mainActivity" v-component="{{currentActivity}}" class="activity"></div>
</div>

In class A, set value for key:

let text = "hai"  
UserDefaults.standard.setValue(text, forKey: "textValue")

In class B, get the value for the text using the key which declared in class A and assign it to respective variable which you need:

var valueOfText  = UserDefaults.value(forKey: "textValue")

There is extensive paramiko API documentation you can find at: http://docs.paramiko.org/en/stable/index.html

I use the following method to execute commands on a password protected client:

import paramiko

nbytes = 4096
hostname = 'hostname'
port = 22
username = 'username' 
password = 'password'
command = 'ls'

client = paramiko.Transport((hostname, port))
client.connect(username=username, password=password)

stdout_data = []
stderr_data = []
session = client.open_channel(kind='session')
session.exec_command(command)
while True:
    if session.recv_ready():
        stdout_data.append(session.recv(nbytes))
    if session.recv_stderr_ready():
        stderr_data.append(session.recv_stderr(nbytes))
    if session.exit_status_ready():
        break

print 'exit status: ', session.recv_exit_status()
print ''.join(stdout_data)
print ''.join(stderr_data)

session.close()
client.close()

You need to attach a click event handler and clear the contents of the textarea from that handler.

HTML

<input type="button" value="Clear" id="clear"> 
<textarea id='output' rows=20 cols=90></textarea>

JS

var input = document.querySelector('#clear');
var textarea = document.querySelector('#output');

input.addEventListener('click', function () {
    textarea.value = '';
}, false);

and here's the working demo.

As stated by Oracle, JavaFX is the next step in their Java based rich client strategy. Accordingly, this is what I recommend for your situation:

What would be easier and cleaner to maintain

• JavaFX has introduced several improvements over Swing, such as, possibility to markup UIs with FXML, and theming with CSS. It has great potential to write a modular, clean & maintainable code.

What would be faster to build from scratch

• This is highly dependent on your skills and the tools you use.
  • For swing, various IDEs offer tools for rapid development. The best I personally found is the GUI builder in NetBeans.
  • JavaFX has support from various IDEs as well, though not as mature as the support Swing has at the moment. However, its support for markup in FXML & CSS make GUI development on JavaFX intuitive.

MVC Pattern Support

• JavaFX is very friendly with MVC pattern, and you can cleanly separate your work as: presentation (FXML, CSS), models(Java, domain objects) and logic(Java).
• IMHO, the MVC support in Swing isn't very appealing. The flow you'll see across various components lacks consistency.

For more info, please take a look these FAQ post by Oracle regarding JavaFX here.

In my travels I have found that if you try either of the following while you are recording audio, the device will not vibrate even if it is enabled.

1) AudioServicesPlayAlertSound(kSystemSoundID_Vibrate);
2) AudioServicesPlaySystemSound(kSystemSoundID_Vibrate);

My method was called at a specific time in the measurement of the devices movements. I had to stop the recording and then restart it after the vibration had occurred.

It looked like this.

-(void)vibrate {
    [recorder stop];
    AudioServicesPlaySystemSound (kSystemSoundID_Vibrate);
    [recorder start];
}

recorder is an AVRecorder instance.

Hope this helps others that have had the same problem before.

See Python's document on sharing global variables across modules:

The canonical way to share information across modules within a single program is to create a special module (often called config or cfg).

config.py:

x = 0   # Default value of the 'x' configuration setting

Import the config module in all modules of your application; the module then becomes available as a global name.

main.py:

import config
print (config.x)

or

from config import x
print (x)

In general, don’t use from modulename import *. Doing so clutters the importer’s namespace, and makes it much harder for linters to detect undefined names.

use:

array.splice(2, 1);

This removes one item from the array, starting at index 2 (3rd item)

Here is another way you can change the selected option of a <select> element in javascript. You can use

document.getElementById('salesperson').selectedIndex=1;

Setting it to 1 will make the second element of the dropdown selected. The select element index start from 0.

Here is a sample code. Check if you can use this type of approach:

<html>
<head>
<script language="javascript">

function changeSelected() { 
document.getElementById('salesperson').selectedIndex=1;

} 

</script>
</head>
<body>
<form name="f1">

<select id="salesperson" > 
   <option value"">james</option>
   <option value"">john</option>  
</select> 
<input type="button" value="Change Selected" onClick="changeSelected();">

</form>
</body>
</html>

Share your folder for "everyone" or some specific group and try this:

<a href="file://YOURSERVERNAME/AmberCRO%20SOP/2011-07-05/SOP-SOP-3.0.pdf"> Download PDF </a> 

When you put the username and password in front of the host, this data is not sent that way to the server. It is instead transformed to a request header depending on the authentication schema used. Most of the time this is going to be Basic Auth which I describe below. A similar (but significantly less often used) authentication scheme is Digest Auth which nowadays provides comparable security features.

With Basic Auth, the HTTP request from the question will look something like this:

GET / HTTP/1.1
Host: example.com
Authorization: Basic Zm9vOnBhc3N3b3Jk

The hash like string you see there is created by the browser like this: base64_encode(username + ":" + password).

To outsiders of the HTTPS transfer, this information is hidden (as everything else on the HTTP level). You should take care of logging on the client and all intermediate servers though. The username will normally be shown in server logs, but the password won't. This is not guaranteed though. When you call that URL on the client with e.g. curl, the username and password will be clearly visible on the process list and might turn up in the bash history file.

When you send passwords in a GET request as e.g. http://example.com/login.php?username=me&password=secure the username and password will always turn up in server logs of your webserver, application server, caches, ... unless you specifically configure your servers to not log it. This only applies to servers being able to read the unencrypted http data, like your application server or any middleboxes such as loadbalancers, CDNs, proxies, etc. though.

Basic auth is standardized and implemented by browsers by showing this little username/password popup you might have seen already. When you put the username/password into an HTML form sent via GET or POST, you have to implement all the login/logout logic yourself (which might be an advantage and allows you to more control over the login/logout flow for the added "cost" of having to implement this securely again). But you should never transfer usernames and passwords by GET parameters. If you have to, use POST instead. The prevents the logging of this data by default.

When implementing an authentication mechanism with a user/password entry form and a subsequent cookie-based session as it is commonly used today, you have to make sure that the password is either transported with POST requests or one of the standardized authentication schemes above only.

Concluding I could say, that transfering data that way over HTTPS is likely safe, as long as you take care that the password does not turn up in unexpected places. But that advice applies to every transfer of any password in any way.

You can also do it "the joiner way" by inserting "U+2060 Word Joiner".

If Accept-Charset permits, the unicode character itself can be inserted directly into the HTML output.

Otherwise, it can be done using entity encoding. E.g. to join the text red-brown, use:

red-⁠brown

or (decimal equivalent):

red-⁠brown

. Another usable character is "U+FEFF Zero Width No-break Space"^{[⁠ ⁠1 ]}:

red-brown

and (decimal equivalent):

red-brown

^{[1]: Note that while this method still works in major browsers like Chrome, it has been deprecated since Unicode 3.2.}

Comparison of "the joiner way" with "U+2011 Non-breaking Hyphen":

• The word joiner can be used for all other characters, not just hyphens.

• When using the word joiner, most renderers will rasterize the text identically. On Chrome, FireFox, IE, and Opera, the rendering of normal hyphens, eg:

  a-b-c-d-e-f-g-h-i-j-k-l-m-n-o-p-q-r-s-t-u-v-w-x-y-z

  is identical to the rendering of normal hyphens (with U+2060 Word Joiner), eg:

  a-⁠b-⁠c-⁠d-⁠e-⁠f-⁠g-⁠h-⁠i-⁠j-⁠k-⁠l-⁠m-⁠n-⁠o-⁠p-⁠q-⁠r-⁠s-⁠t-⁠u-⁠v-⁠w-⁠x-⁠y-⁠z

  while the above two renders differ from the rendering of "Non-breaking Hyphen", eg:

  a‑b‑c‑d‑e‑f‑g‑h‑i‑j‑k‑l‑m‑n‑o‑p‑q‑r‑s‑t‑u‑v‑w‑x‑y‑z

  . (The extent of the difference is browser-dependent and font-dependent. E.g. when using a font declaration of "arial", Firefox and IE11 show relatively huge variations, while Chrome and Opera show smaller variations.)

Comparison of "the joiner way" with <span class=c1></span> (CSS .c1 {white-space:nowrap;}) and <nobr></nobr>:

• The word joiner can be used for situations where usage of HTML tags is restricted, e.g. forms of websites and forums.

• On the spectrum of presentation and content, majority will consider the word joiner to be closer to content, when compared to tags.

^{• As tested on Windows 8.1 Core 64-bit using:
    • IE 11.0.9600.18205
    • Firefox 43.0.4
    • Chrome 48.0.2564.109 (Official Build) m (32-bit)
    • Opera 35.0.2066.92}

Please refer the link from JQuery

http://api.jquery.com/keypress/

It says

The keypress event is sent to an element when the browser registers keyboard input. This is similar to the keydown event, except that modifier and non-printing keys such as Shift, Esc, and delete trigger keydown events but not keypress events. Other differences between the two events may arise depending on platform and browser.

That means you can not use keypress in case of arrows.

Please try module pexpect. Here is my code:

import pexpect
remove = pexpect.spawn('sudo dpkg --purge mytool.deb')
remove.logfile = open('log/expect-uninstall-deb.log', 'w')
remove.logfile.write('try to dpkg --purge mytool\n')
if remove.expect(['(?i)password.*']) == 0:
    # print "successfull"
    remove.sendline('mypassword')
    time.sleep(2)
    remove.expect(pexpect.EOF,5)
else:
    raise AssertionError("Fail to Uninstall deb package !")

This can be checked using regular expression.

 ###    
    echo $var|egrep '^[0-9]+$'
    if [ $? -eq 0 ]; then
        echo "$var is a number"
    else
        echo "$var is not a number"
    fi

To make the file public before uploading you can use the #withCannedAcl method of PutObjectRequest:

myAmazonS3Client.putObject(new PutObjectRequest('some-grails-bucket',  'somePath/someKey.jpg', new    File('/Users/ben/Desktop/photo.jpg')).withCannedAcl(CannedAccessControlList.PublicRead))

A foreign key with a cascade delete means that if a record in the parent table is deleted, then the corresponding records in the child table will automatically be deleted. This is called a cascade delete.

You are saying in a opposite way, this is not that when you delete from child table then records will be deleted from parent table.

UPDATE 1:

ON DELETE CASCADE option is to specify whether you want rows deleted in a child table when corresponding rows are deleted in the parent table. If you do not specify cascading deletes, the default behaviour of the database server prevents you from deleting data in a table if other tables reference it.

If you specify this option, later when you delete a row in the parent table, the database server also deletes any rows associated with that row (foreign keys) in a child table. The principal advantage to the cascading-deletes feature is that it allows you to reduce the quantity of SQL statements you need to perform delete actions.

So it's all about what will happen when you delete rows from Parent table not from child table.

So in your case when user removes entries from CATs table then rows will be deleted from books table. :)

Hope this helps you :)

One way to test private methods is through reflection. This applies to NUnit and XUnit, too:

MyObject objUnderTest = new MyObject();
MethodInfo methodInfo = typeof(MyObject).GetMethod("SomePrivateMethod", BindingFlags.NonPublic | BindingFlags.Instance);
object[] parameters = {"parameters here"};
methodInfo.Invoke(objUnderTest, parameters);

char c = 'A';
printf("ptr: %p,\tvalue: %c,\tand also address: %zu", &c, c, &c);

Result:

ptr: 0x7ffc48e5105f,    value: A,    and also address: 140721531457631

If this string is for presentation to the end user, you should use NSNumberFormatter. This will add thousands separators, and will honor the localization settings for the user:

NSInteger n = 10000;
NSNumberFormatter *formatter = [[NSNumberFormatter alloc] init];
formatter.numberStyle = NSNumberFormatterDecimalStyle;
NSString *string = [formatter stringFromNumber:@(n)];

In the US, for example, that would create a string 10,000, but in Germany, that would be 10.000.

I use this method and it works well:

1- Copy And paste the .jar files under the libs folder.

2- Add compile fileTree(dir: 'libs', include: '*.jar') to dependencies in build.gradle then all the jars in the libs folder will be included..

3- Right click on libs folder and select 'Add as library' option from the list.

A global variable for using in controllers; you can set in AppServiceProvider like this :

public function boot()
{
    $company=DB::table('company')->where('id',1)->first();
    config(['yourconfig.company' => $company]);
}

usage

config('yourconfig.company');

A Java Bean is a Java class (conceptual) that should follow the following conventions:

1. It should have a no-argument constructor.
2. It should be serializable.
3. It should provide methods to set and get the values of the properties, known as getter and setter methods.

It is a reusable software component. It can encapsulate many objects into one object so that same object can be accessed from multiples places and is a step towards easy maintenance of code.

Unfortunately that approach is not portable C++ (so far).

All standard names are in namespace std and moreover you cannot know which names are NOT defined by including and header (in other words it's perfectly legal for an implementation to declare the name std::string directly or indirectly when using #include <vector>).

Despite this however you are required by the language to know and tell the compiler which standard header includes which part of the standard library. This is a source of portability bugs because if you forget for example #include <map> but use std::map it's possible that the program compiles anyway silently and without warnings on a specific version of a specific compiler, and you may get errors only later when porting to another compiler or version.

In my opinion there are no valid technical excuses because this is necessary for the general user: the compiler binary could have all standard namespace built in and this could actually increase the performance even more than precompiled headers (e.g. using perfect hashing for lookups, removing standard headers parsing or loading/demarshalling and so on).

The use of standard headers simplifies the life of who builds compilers or standard libraries and that's all. It's not something to help users.

However this is the way the language is defined and you need to know which header defines which names so plan for some extra neurons to be burnt in pointless configurations to remember that (or try to find and IDE that automatically adds the standard headers you use and removes the ones you don't... a reasonable alternative).

Needs ensure library but you can compare list by:

ensure([1, 2]).contains_only([2, 1])

This will not raise assert exception. Documentation of thin is really thin so i would recommend to look at ensure's codes on github

if you use the site http://www.lfd.uci.edu/~gohlke/pythonlibs/#mysql-python , download the file:

• mysqlclient-1.3.6-cp34-none-win32.whl or

• mysqlclient-1.3.6-cp34-none-win_amd64.whl

depending on the version of python you have (these are for python 3.4) and the type of windows you have (x64 or x32)

extract this file into C:\Python34\Lib\site-packages and your project will work

If you want to keep adding a new object to the array i've been using:

_methodName = (para1, para2) => {
  this.setState({
    arr: this.state.arr.concat({para1, para2})
  })
}

For update() and saveOrUpdate() methods, id generator value should be there in the database. For the save() method, id generator is not required.

I find that some of these answers are vague and complicated, I find the best way to figure out these things for sure is to just open up the console and test it yourself.

var x;

x == null            // true
x == undefined       // true
x === null           // false
x === undefined      // true

var y = null;

y == null            // true
y == undefined       // true
y === null           // true
y === undefined      // false

typeof x             // 'undefined'
typeof y             // 'object'

var z = {abc: null};

z.abc == null        // true
z.abc == undefined   // true
z.abc === null       // true
z.abc === undefined  // false

z.xyz == null        // true
z.xyz == undefined   // true
z.xyz === null       // false
z.xyz === undefined  // true

null = 1;            // throws error: invalid left hand assignment
undefined = 1;       // works fine: this can cause some problems

So this is definitely one of the more subtle nuances of JavaScript. As you can see, you can override the value of undefined, making it somewhat unreliable compared to null. Using the == operator, you can reliably use null and undefined interchangeably as far as I can tell. However, because of the advantage that null cannot be redefined, I might would use it when using ==.

For example, variable != null will ALWAYS return false if variable is equal to either null or undefined, whereas variable != undefined will return false if variable is equal to either null or undefined UNLESS undefined is reassigned beforehand.

You can reliably use the === operator to differentiate between undefined and null, if you need to make sure that a value is actually undefined (rather than null).

According to the ECMAScript 5 spec:

• Both Null and Undefined are two of the six built in types.

4.3.9 undefined value

primitive value used when a variable has not been assigned a value

4.3.11 null value

primitive value that represents the intentional absence of any object value

Based on Doug Shore's method but make it more copy-paste friendly

You can do it like below in SQL Server

ALTER TABLE one
ADD two_id int foreign key
REFERENCES two(id)

Here is an example

Query query = em.createQuery("from Student");
             java.util.List list = query.getResultList();
             for (int i = 0; i < list.size(); i++) 
             {

                 student = (Student) list.get(i);
                 System.out.println(student.id  + "  " + student.age + " " + student.name + " " + student.prenom);

             }

According to the documentation of Spring-Cloud-Config there is one extra scope next to the existing five. It is @RefreshScope.

This is the short description of RefreshScope:

When there is a configuration change, a Spring @Bean that is marked as @RefreshScope gets special treatment. This feature addresses the problem of stateful beans that only get their configuration injected when they are initialized. For instance, if a DataSource has open connections when the database URL is changed via the Environment, you probably want the holders of those connections to be able to complete what they are doing. Then, the next time something borrows a connection from the pool, it gets one with the new URL.

Sometimes, it might even be mandatory to apply the @RefreshScope annotation on some beans which can be only initialized once. If a bean is "immutable", you will have to either annotate the bean with @RefreshScope or specify the classname under the property key spring.cloud.refresh.extra-refreshable.

Refresh scope beans are lazy proxies that initialize when they are used (that is, when a method is called), and the scope acts as a cache of initialized values. To force a bean to re-initialize on the next method call, you must invalidate its cache entry.

The RefreshScope is a bean in the context and has a public refreshAll() method to refresh all beans in the scope by clearing the target cache. The /refresh endpoint exposes this functionality (over HTTP or JMX). To refresh an individual bean by name, there is also a refresh(String) method.

gzip > stdin.gz perhaps? Otherwise, you need to flesh out your question.

If you want know, the how may nodejs processes running then you can use this command

ps -aef | grep node

So it will give list of nodejs process with it's project name. It will be helpful when you are running multipe nodejs application & you want kill specific process for the specific project.

Above command will give output like

XXX  12886  1741  1 12:36 ?        00:00:05 /home/username/.nvm/versions/node/v9.2.0/bin/node --inspect-brk=43443 /node application running path.

So to kill you can use following command

kill -9 12886

So it will kill the spcefic node process

Here is the C# method. Int.TryParse Method (String, Int32)

Unless you need to identify the columns automatically, I found this to be the simplest solution:

df$name <- as.factor(df$name)

This makes column name in dataframe df a factor.

if anyone gets in here again this worked for me...

"aoColumnDefs": [{ "bVisible": false, "aTargets": [0] }]

A minor update to this: a sender should never set the Return-Path: header. There's no such thing as a Return-Path: header for a message in transit. That header is set by the MTA that makes final delivery, and is generally set to the value of the 5321.From unless the local system needs some kind of quirky routing.

It's a common misunderstanding because users rarely see an email without a Return-Path: header in their mailboxes. This is because they always see delivered messages, but an MTA should never see a Return-Path: header on a message in transit. See http://tools.ietf.org/html/rfc5321#section-4.4

The boolean value for NO in Swift is false.

button.isEnabled = false

should do it.

Here is the Swift documentation for UIControl's isEnabled property.

document.getElementById('id').style = 'left: 55%; z-index: 999; overflow: hidden; width: 0px; height: 0px; opacity: 0; display: none;';

works for me

I want to work with exec_query of the ActiveRecord class, because it returns the mapping of the query transforming into object, so it gets very practical and productive to iterate with the objects when the subject is Raw SQL.

Example:

values = ActiveRecord::Base.connection.exec_query("select * from clients")
p values

and return this complete query:

[{"id": 1, "name": "user 1"}, {"id": 2, "name": "user 2"}, {"id": 3, "name": "user 3"}]

To get only list of values

p values.rows

[[1, "user 1"], [2, "user 2"], [3, "user 3"]]

To get only fields columns

p values.columns

["id", "name"]

Use SelectList to bind @HtmlDropdownListFor and specify selectedValue parameter in it.

http://msdn.microsoft.com/en-us/library/dd492553(v=vs.108).aspx

Example : you can do like this for getting venderid

@Html.DropDownListFor(m => m.VendorId,Model.Vendor)


   public class MobileViewModel 
   {          
    public List<tbInsertMobile> MobileList;
    public SelectList Vendor { get; set; }
    public int VenderID{get;set;}
   }
   [HttpPost]
   public ActionResult Action(MobileViewModel model)
   {
            var Id = model.VenderID;

For Elasticbeanstalk environments, you can apply a key-value pair to a running instance like this:

• Create a key-value pair from EC2 -> Key Pairs (Under NETWORK & SECURITY tab)
• Go to Elasticbeanstalk and click on your application
• Go to configuration page and modify security settings
• Choose your EC2 key pair and click Apply
• Click confirm to confirm the update. It will terminate the environment and apply the key value to your environment.

In your Apache .htaccess file:

#Create filter to match files you want to cache

import re
pattern = re.compile("<(\d{4,5})>")

for i, line in enumerate(open('test.txt')):
    for match in re.finditer(pattern, line):
        print 'Found on line %s: %s' % (i+1, match.group())

A couple of notes about the regex:

• You don't need the ? at the end and the outer (...) if you don't want to match the number with the angle brackets, but only want the number itself
• It matches either 4 or 5 digits between the angle brackets

Update: It's important to understand that the match and capture in a regex can be quite different. The regex in my snippet above matches the pattern with angle brackets, but I ask to capture only the internal number, without the angle brackets.

More about regex in python can be found here : Regular Expression HOWTO

json is a built-in module, you don't need to install it with pip.

LENGTH() does return the string length (just verified). I suppose that your data is padded with blanks - try

SELECT typ, LENGTH(TRIM(t1.typ))
FROM AUTA_VIEW t1;

instead.

As OraNob mentioned, another cause could be that CHAR is used in which case LENGTH() would also return the column width, not the string length. However, the TRIM() approach also works in this case.
