You haven't reserved enough space in your vector object to hold the contents of your set.

std::vector<double> output(input.size());
std::copy(input.begin(), input.end(), output.begin());

1. Create a UNIQUE constraint on your subs_email column, if one does not already exist:

   ALTER TABLE subs ADD UNIQUE (subs_email)
   

2. Use INSERT ... ON DUPLICATE KEY UPDATE:

   INSERT INTO subs
     (subs_name, subs_email, subs_birthday)
   VALUES
     (?, ?, ?)
   ON DUPLICATE KEY UPDATE
     subs_name     = VALUES(subs_name),
     subs_birthday = VALUES(subs_birthday)
   

You can use the VALUES(col_name) function in the UPDATE clause to refer to column values from the INSERT portion of the INSERT ... ON DUPLICATE KEY UPDATE - dev.mysql.com

3. Note that I have used parameter placeholders in the place of string literals, as one really should be using parameterised statements to defend against SQL injection attacks.

Usually this means that your schema and mapping files are not in synch and there is a renamed or missing column someplace.

Atom does not have a specific comment-block function, but if you select more rows and then use the normal ctrl-/ (Windows or Linux) cmd-/ (Mac), it will comment all the lines.

>>> takeClosest = lambda num,collection:min(collection,key=lambda x:abs(x-num))
>>> takeClosest(5,[4,1,88,44,3])
4

A lambda is a special way of writing an "anonymous" function (a function that doesn't have a name). You can assign it any name you want because a lambda is an expression.

The "long" way of writing the the above would be:

def takeClosest(num,collection):
   return min(collection,key=lambda x:abs(x-num))

The following steps are necessary to create .exe i.e. executable files which are as 1) Open visual studio framework 2) Then, create a new project or application 3) Build or execute your application by pressing F5

You can add a form onsubmit handler, something like:

<form onsubmit="return validate();">

</form>


<script>function validate() {
 // check if input is bigger than 3
 var value = document.getElementById('titleeee').value;
 if (value.length < 3) {
   return false; // keep form from submitting
 }

 // else form is good let it submit, of course you will 
 // probably want to alert the user WHAT went wrong.

 return true;
}</script>

The has_many :choices creates an association named choices, not choice. Try using current_user.choices instead.

See the ActiveRecord::Associations documentation for information about about the has_many magic.

Please be aware, this is a simplified explanation intended as a first step in seeking to understand this complex functionality.

May be helpful for visual learners who want to visualise what their project state looks like after each of these commands:

For those who use Terminal with colour turned on (git config --global color.ui auto):

git reset --soft A and you will see B and C's stuff in green (staged and ready to commit)

git reset --mixed A (or git reset A) and you will see B and C's stuff in red (unstaged and ready to be staged (green) and then committed)

git reset --hard A and you will no longer see B and C's changes anywhere (will be as if they never existed)

Or for those who use a GUI program like 'Tower' or 'SourceTree'

git reset --soft A and you will see B and C's stuff in the 'staged files' area ready to commit

git reset --mixed A (or git reset A) and you will see B and C's stuff in the 'unstaged files' area ready to be moved to staged and then committed

git reset --hard A and you will no longer see B and C's changes anywhere (will be as if they never existed)

Width: MediaQuery.of(context).size.width,

Height: MediaQuery.of(context).size.height,

Unfortunately, setTimeout() is the only reliable way (not the only way, but the only reliable way) to pause the execution of the script without blocking the UI.

It's not that hard to use actually, instead of writing this:

var x = 1;

// Place mysterious code that blocks the thread for 100 ms.

x = x * 3 + 2;
var y = x / 2;

you use setTimeout() to rewrite it this way:

var x = 1;
var y = null; // To keep under proper scope

setTimeout(function() {
    x = x * 3 + 2;
    y = x / 2;
}, 100);

I understand that using setTimeout() involves more thought than a desirable sleep() function, but unfortunately the later doesn't exist. Many workarounds are there to try to implement such functions. Some using busy loops:

function sleep(milliseconds) {
  var start = new Date().getTime();
  for (var i = 0; i < 1e7; i++) {
    if ((new Date().getTime() - start) > milliseconds){
      break;
    }
  }
}

others using an XMLHttpRequest tied with a server script that sleeps for a amount of time before returning a result.

Unfortunately, those are workarounds and are likely to cause other problems (such as freezing browsers). It is recommended to simply stick with the recommended way, which is setTimeout()).

You need to pass an array of element to jsx. The problem is that forEach does not return anything (i.e it returns undefined). So it's better to use map because map returns an array:

class QuestionSet extends Component {
render(){ 
    <div className="container">
       <h1>{this.props.question.text}</h1>
       {this.props.question.answers.map((answer, i) => {     
           console.log("Entered");                 
           // Return the element. Also pass key     
           return (<Answer key={answer} answer={answer} />) 
        })}
}

export default QuestionSet;

$(document).keydown(function(e){
    if (e.which == 37) { 
       alert("left pressed");
       return false;
    }
});

Character codes:

37 - left

38 - up

39 - right

40 - down

try something like

public static Document loadXML(String xml) throws Exception
{
   DocumentBuilderFactory fctr = DocumentBuilderFactory.newInstance();
   DocumentBuilder bldr = fctr.newDocumentBuilder();
   InputSource insrc = new InputSource(new StringReader(xml));
   return bldr.parse(insrc);
}

I suggest using "outline" instead of "border". For example: outline: 1px solid #1e5180.

Other languages such as PHP accept a parameter for break (i.e. break 2;) to specify the amount of nested loop levels you want to break out of, C++ however doesn't. You will have to work it out by using a boolean that you set to false prior to the loop, set to true in the loop if you want to break, plus a conditional break after the nested loop, checking if the boolean was set to true and break if yes.

You can achieve this by using Newtonsoft.json. Install Newtonsoft.json from NuGet. And then:

using Newtonsoft.Json;

var jsonString = JsonConvert.SerializeObject(obj);

GoDaddy shared server solution

I had the same issue when trying to deploy separate Laravel project on a subdomain level.

File structure

- public_html (where the main web app resides)
    [works fine]

    - booking.mydomain.com (folder for separate Laravel project)
        [showing error 403 forbidden]

Solution

1. go to cPanel of your GoDaddy account

2. open File Manager

3. browse to the folder that shows 403 forbidden error

4. in the File Manager, right-click on the folder (in my case booking.mydomain.com)

5. select Change Permissions

6. select following checkboxes

    a) user - read, write, execute
    b) group - read, execute
    c) world - read, execute
   
    Permission code must display as 755
   

7. Click change permissions

Just for fun, another approach would be to just leave the paging and horizontal scrolling set, add a method that changes the order of the array items to convert from 'top to bottom, left to right' to visually 'left to right, top to bottom' and fill the in-between cells with empty hidden cells to make the spacing right. In case of 7 items in a grid of 9, this would go like this:

[1][4][7]
[2][5][ ]
[3][6][ ]

should become

[1][2][3]
[4][5][6]
[7][ ][ ]

so 1=1, 2=4, 3=7 etc. and 6=empty. You can reorder them by calculating the total number of rows and columns, then calculate the row and column number for each cell, change the row for the column and vice versa and then you have the new indexes. When the cell doesn't have a value corresponding to the image you can return an empty cell and set cell.hidden = YES; to it.

It works quite well in a soundboard app I built, so if anyone would like working code I'll add it. Only little code is required to make this trick work, it sounds harder than it is!

Update

I doubt this is the best solution, but by request here's working code:

- (void)viewDidLoad {
    // Fill an `NSArray` with items in normal order
    items = [NSMutableArray arrayWithObjects:
             [NSDictionary dictionaryWithObjectsAndKeys:@"Some label 1", @"label", @"Some value 1", @"value", nil],
             [NSDictionary dictionaryWithObjectsAndKeys:@"Some label 2", @"label", @"Some value 2", @"value", nil],
             [NSDictionary dictionaryWithObjectsAndKeys:@"Some label 3", @"label", @"Some value 3", @"value", nil],
             [NSDictionary dictionaryWithObjectsAndKeys:@"Some label 4", @"label", @"Some value 4", @"value", nil],
             [NSDictionary dictionaryWithObjectsAndKeys:@"Some label 5", @"label", @"Some value 5", @"value", nil],
              nil
              ];

    // Calculate number of rows and columns based on width and height of the `UICollectionView` and individual cells (you might have to add margins to the equation based on your setup!)
    CGFloat w = myCollectionView.frame.size.width;
    CGFloat h = myCollectionView.frame.size.height;
    rows = floor(h / cellHeight);
    columns = floor(w / cellWidth);
}

// Calculate number of sections
- (NSInteger)numberOfSectionsInCollectionView:(UICollectionView *)collectionView {
    return ceil((float)items.count / (float)(rows * columns));
}

// Every section has to have every cell filled, as we need to add empty cells as well to correct the spacing
- (NSInteger)collectionView:(UICollectionView *)collectionView numberOfItemsInSection:(NSInteger)section {
    return rows*columns;
}

// And now the most important one
- (UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath {
    UICollectionViewCell *cell = [collectionView dequeueReusableCellWithReuseIdentifier@"myIdentifier" forIndexPath:indexPath];

    // Convert rows and columns
    int row = indexPath.row % rows;
    int col = floor(indexPath.row / rows);
    // Calculate the new index in the `NSArray`
    int newIndex = ((int)indexPath.section * rows * columns) + col + row * columns;

    // If the newIndex is within the range of the items array we show the cell, if not we hide it
    if(newIndex < items.count) {
        NSDictionary *item = [items objectAtIndex:newIndex];
        cell.label.text = [item objectForKey:@"label"];
        cell.hidden = NO;
    } else {
        cell.hidden = YES;
    }

    return cell;
}

If you'd like to use the didSelectItemAtIndexPath method you have to use the same conversion that is used in cellForItemAtIndexPath to get the corresponding item. If you have cell margins you need to add them to the rows and columns calculation, as those have to be correct in order for this to work.

String[] string=new String[60];
System.out.println(string.length);

it is initialization and getting the STRING LENGTH code in very simple way for beginners

The projects you are trying to open are in the new .NET Core csproj format. This means you need to use Visual Studio 2017 which supports this new format.

For a little bit of history, initially .NET Core used project.json instead of *.csproj. However, after some considerable internal deliberation at Microsoft, they decided to go back to csproj but with a much cleaner and updated format. However, this new format is only supported in VS2017.

If you want to open the projects but don't want to wait until March 7^th for the official VS2017 release, you could use Visual Studio Code instead.

char c = '1';
int i = (int)(c-'0');

and you can create a static method out of it:

static int ToInt(this char c)
{
    return (int)(c - '0');
}

Just for the sake of completeness, appending values to a vector in a for loop is not really the philosophy in R. R works better by operating on vectors as a whole, as @BrodieG pointed out. See if your code can't be rewritten as:

ouput <- sapply(values, function(v) return(2*v))

Output will be a vector of return values. You can also use lapply if values is a list instead of a vector.

Check your antivirus and firewall settings.

From one day to the other, git did not work anymore. With what is described above, I found that Kaspersky puts a self-signed Anti-virus personal root certificate in the middle. I did not manage to let Git accept that certificate following the instructions above. I gave up on that. What works for me is to disable the feature to Scan encrypted connections.

1. Open Kaspersky
2. Settings > Additional > Network > Do not scan encrypted connections

After this, git works again with sslVerify enabled.

Note. This is still not satisfying for me, because I would like to have that feature of my Anti-Virus active. In the advanced settings, Kaspersky shows a list of websites that will not work with that feature. Github is not listed as one of them. I will check it at the Kaspersky forum. There seem to be some topics, e.g. https://forum.kaspersky.com/index.php?/topic/395220-kis-interfering-with-git/&tab=comments#comment-2801211

I had this same problem, read this post, but ended building this solution that selects the divs dynamically by fetching the ID from a custom class on the href using JQuery's attr() function.

Here's the JQuery:

$('a.custom_class').click(function(e) {
  var div = $(this).attr('href');
  $(div).toggle('fast');
  e.preventDefault();
}

And you just have to create a link like this then in the HTML:

<a href="#" class="#1">Link Text</a>
<div id="1">Div Content</div>

Why not set ON CASCADE DELETE on Foreign Key patron_info.pid?

This is actual version of benchmark provided by @cd1 (Go 1.8, linux x86_64) with the fixes of bugs mentioned by @icza and @PickBoy.

Bytes.Buffer is only 7 times faster than direct string concatenation via + operator.

package performance_test

import (
    "bytes"
    "fmt"
    "testing"
)

const (
    concatSteps = 100
)

func BenchmarkConcat(b *testing.B) {
    for n := 0; n < b.N; n++ {
        var str string
        for i := 0; i < concatSteps; i++ {
            str += "x"
        }
    }
}

func BenchmarkBuffer(b *testing.B) {
    for n := 0; n < b.N; n++ {
        var buffer bytes.Buffer
        for i := 0; i < concatSteps; i++ {
            buffer.WriteString("x")
        }
    }
}

Timings:

BenchmarkConcat-4                             300000          6869 ns/op
BenchmarkBuffer-4                            1000000          1186 ns/op

Another interesting usecase for split in Hive is when, for example, a column ipname in the table has a value "abc11.def.ghft.com" and you want to pull "abc11" out:

SELECT split(ipname,'[\.]')[0] FROM tablename;

Encountered similar problem: parsing CSV file with special characters like é, è, ö etc ...

The following worked fine for me:

To represent the characters correctly on the html page, the header was needed :

header('Content-Type: text/html; charset=UTF-8');

In order to parse every character correctly, I used:

utf8_encode(fgets($file));

Dont forget to use in all following string operations the 'Multibyte String Functions', like:

mb_strtolower($value, 'UTF-8');

Just Change the Connection mysql string to 127.0.0.1 and it will work

You can reference those remote tracking branches ~(listed with git branch -r) with the name of their remote.

You need to fetch the remote branch:

git fetch origin aRemoteBranch

If you want to merge one of those remote branches on your local branch:

git checkout master
git merge origin/aRemoteBranch

Note 1: For a large repo with a long history, you will want to add the --depth=1 option when you use git fetch.

Note 2: These commands also work with other remote repos so you can setup an origin and an upstream if you are working on a fork.

Note 3: user3265569 suggests the following alias in the comments:

From aLocalBranch, run git combine remoteBranch
Alias:

combine = !git fetch origin ${1} && git merge origin/${1}

Opposite scenario: If you want to merge one of your local branch on a remote branch (as opposed to a remote branch to a local one, as shown above), you need to create a new local branch on top of said remote branch first:

git checkout -b myBranch origin/aBranch
git merge anotherLocalBranch

The idea here, is to merge "one of your local branch" (here anotherLocalBranch) to a remote branch (origin/aBranch).
For that, you create first "myBranch" as representing that remote branch: that is the git checkout -b myBranch origin/aBranch part.
And then you can merge anotherLocalBranch to it (to myBranch).

You could use timeit like this to test a script named module.py

$ python -mtimeit -s 'import module'

As an addition

basically the number of columns have to be equal to the number of columns in the GROUP BY clause

is not a correct statement.

• Any attribute which is not a part of GROUP BY clause can not be used for selection
• Any attribute which is a part of GROUP BY clause can be used for selection but not mandatory.

You can always create an array of pointers , pointing to car objects and then create objects, in a for loop, as you want and save their address in the array , for example :

#include <iostream>
class Car
{
private:
  Car(){};
  int _no;
public:
  Car(int no)
  {
    _no=no;
  }
  void printNo()
  {
    std::cout<<_no<<std::endl;
  }
};
void printCarNumbers(Car *cars, int length)
{
    for(int i = 0; i<length;i++)
         std::cout<<cars[i].printNo();
}

int main()
{
  int userInput = 10;
  Car **mycars = new Car*[userInput];
  int i;
  for(i=0;i<userInput;i++)
      mycars[i] = new Car(i+1);

note new method !!!

  printCarNumbers_new(mycars,userInput);


  return 0;
}    

All you have to change in new method is handling cars as pointers than static objects in parameter and when calling method printNo() for example :

void printCarNumbers_new(Car **cars, int length)
{
    for(int i = 0; i<length;i++)
         std::cout<<cars[i]->printNo();
}

at the end of main is good to delete all dynamicly allocated memory like this

for(i=0;i<userInput;i++)
  delete mycars[i];      //deleting one obgject
delete[] mycars;         //deleting array of objects

Hope I helped, cheers!

This method worked in my case.

video=getElementsByTagName('video');
function removeControls(video){
  video.removeAttribute('controls');
}
window.onload=removeControls(video);

I just give other option for this question - you need to use '.dt' in your code:

import pandas as pd_x000D_
_x000D_
df.index = pd.to_datetime(df.index)_x000D_
_x000D_
#for get year_x000D_
df.index.dt.year_x000D_
_x000D_
#for get month_x000D_
df.index.dt.month_x000D_
_x000D_
#for get day_x000D_
df.index.dt.day_x000D_
_x000D_
#for get hour_x000D_
df.index.dt.hour_x000D_
_x000D_
#for get minute_x000D_
df.index.dt.minute

In the source header you can declare:

#!/usr/bin/env python
# -*- coding: utf-8 -*-
....

It is described in the PEP 0263:

Then you can use UTF-8 in strings:

#!/usr/bin/env python
# -*- coding: utf-8 -*-

u = 'idzie waz waska drózka'
uu = u.decode('utf8')
s = uu.encode('cp1250')
print(s)

This declaration is not needed in Python 3 as UTF-8 is the default source encoding (see PEP 3120).

In addition, it may be worth verifying that your text editor properly encodes your code in UTF-8. Otherwise, you may have invisible characters that are not interpreted as UTF-8.

Encapsulate hides variables or some implementation that may be changed so often in a class to prevent outsiders access it directly. They must access it via getter and setter methods.

Abstraction is used to hiding something too but in a higher degree(class, interface). Clients use an abstract class(or interface) do not care about who or which it was, they just need to know what it can do.

<style>
    .col {display:table-cell;max-width:50px;width:50px;overflow:hidden;white-space: nowrap;}
</style>
<table>
    <tr>
        <td class="col">123456789123456789</td>
    </tr>
</table>

displays 123456

Making a class static just prevents people from trying to make an instance of it. If all your class has are static members it is a good practice to make the class itself static.

@Simon Goldstone: Thanks for your solution, it can be perfectly applied in my case. The only problem is I had to translate it to VB. But now it is done and to save other people's time (in case they need it) I put it here:

Imports System.Runtime.CompilerServices
Imports System.ComponentModel
Imports System.Linq.Expressions

Public Module HtmlHelpers
    Private Function GetNonNullableModelType(modelMetadata As ModelMetadata) As Type
        Dim realModelType = modelMetadata.ModelType

        Dim underlyingType = Nullable.GetUnderlyingType(realModelType)

        If Not underlyingType Is Nothing Then
            realModelType = underlyingType
        End If

        Return realModelType
    End Function

    Private ReadOnly SingleEmptyItem() As SelectListItem = {New SelectListItem() With {.Text = "", .Value = ""}}

        Dim fi = value.GetType().GetField(value.ToString())

        Dim attributes = DirectCast(fi.GetCustomAttributes(GetType(DescriptionAttribute), False), DescriptionAttribute())

        If Not attributes Is Nothing AndAlso attributes.Length > 0 Then

        Dim enumType As Type = GetNonNullableModelType(metaData)
        Dim values As IEnumerable(Of TEnum) = [Enum].GetValues(enumType).Cast(Of TEnum)()

        Dim items As IEnumerable(Of SelectListItem) = From value In values
            Select New SelectListItem With
            {
                .Text = GetEnumDescription(value),
                .Value = value.ToString(),
                .Selected = value.Equals(metaData.Model)
            }

        ' If the enum is nullable, add an 'empty' item to the collection
        If metaData.IsNullableValueType Then
            items = SingleEmptyItem.Concat(items)
        End If

        Return htmlHelper.DropDownListFor(expression, items, htmlAttributes)
    End Function
End Module

End You use it like this:

@Html.EnumDropDownListFor(Function(model) (model.EnumField))

Bass can do just this. Play from Byte[] in memory or a through file delegates where you return the data, so with that you can play as soon as you have enough data to start the playback..

Use "attr" method in jquery.

$('.test').click(function(){
    var id = $(this).attr('id');
});

We have a similar situation at work, where the production machines have no access to the Internet; therefore everything has to be managed offline and off-host.

Here is what I tried with varied amounts of success:

1. basket which is a small utility that you run on your internet-connected host. Instead of trying to install a package, it will instead download it, and everything else it requires to be installed into a directory. You then move this directory onto your target machine. Pros: very easy and simple to use, no server headaches; no ports to configure. Cons: there aren't any real showstoppers, but the biggest one is that it doesn't respect any version pinning you may have; it will always download the latest version of a package.

2. Run a local pypi server. Used pypiserver and devpi. pypiserver is super simple to install and setup; devpi takes a bit more finagling. They both do the same thing - act as a proxy/cache for the real pypi and as a local pypi server for any home-grown packages. localshop is a new one that wasn't around when I was looking, it also has the same idea. So how it works is your internet-restricted machine will connect to these servers, they are then connected to the Internet so that they can cache and proxy the actual repository.

The problem with the second approach is that although you get maximum compatibility and access to the entire repository of Python packages, you still need to make sure any/all dependencies are installed on your target machines (for example, any headers for database drivers and a build toolchain). Further, these solutions do not cater for non-pypi repositories (for example, packages that are hosted on github).

We got very far with the second option though, so I would definitely recommend it.

Eventually, getting tired of having to deal with compatibility issues and libraries, we migrated the entire circus of servers to commercially supported docker containers.

This means that we ship everything pre-configured, nothing actually needs to be installed on the production machines and it has been the most headache-free solution for us.

We replaced the pypi repositories with a local docker image server.

You can easily use xml (from the Python standard library) to convert to a pandas.DataFrame. Here's what I would do (when reading from a file replace xml_data with the name of your file or file object):

import pandas as pd
import xml.etree.ElementTree as ET
import io

def iter_docs(author):
    author_attr = author.attrib
    for doc in author.iter('document'):
        doc_dict = author_attr.copy()

etree = ET.parse(xml_data) #create an ElementTree object 
doc_df = pd.DataFrame(list(iter_docs(etree.getroot())))

If there are multiple authors in your original document or the root of your XML is not an author, then I would add the following generator:

def iter_author(etree):
    for author in etree.iter('author'):
        for row in iter_docs(author):
            yield row

and change doc_df = pd.DataFrame(list(iter_docs(etree.getroot()))) to doc_df = pd.DataFrame(list(iter_author(etree)))

Have a look at the ElementTree tutorial provided in the xml library documentation.

The other (and perhaps simplest) option for acheiving a clearfix is to use overflow:hidden; on the containing element. For example

.parent {_x000D_
  background: red;_x000D_
  overflow: hidden;_x000D_
}_x000D_
.segment-a {_x000D_
  float: left;_x000D_
}_x000D_
.segment-b {_x000D_
  float: right;_x000D_
}

<div class="parent">_x000D_
  <div class="segment-a">_x000D_
    Float left_x000D_
  </div>_x000D_
  <div class="segment-b">_x000D_
    Float right_x000D_
  </div>_x000D_
</div>

Of course this can only be used in instances where you never wish the content to overflow.

Many answers using external programs, which is not really using Bash.

If you know you will have Bash4 available you should really just use the ${VAR,,} notation (it is easy and cool). For Bash before 4 (My Mac still uses Bash 3.2 for example). I used the corrected version of @ghostdog74 's answer to create a more portable version.

One you can call lowercase 'my STRING' and get a lowercase version. I read comments about setting the result to a var, but that is not really portable in Bash, since we can't return strings. Printing it is the best solution. Easy to capture with something like var="$(lowercase $str)".

How this works

The way this works is by getting the ASCII integer representation of each char with printf and then adding 32 if upper-to->lower, or subtracting 32 if lower-to->upper. Then use printf again to convert the number back to a char. From 'A' -to-> 'a' we have a difference of 32 chars.

Using printf to explain:

$ printf "%d\n" "'a"
97
$ printf "%d\n" "'A"
65

97 - 65 = 32

And this is the working version with examples.
Please note the comments in the code, as they explain a lot of stuff:

#!/bin/bash

# lowerupper.sh

# Prints the lowercase version of a char
lowercaseChar(){
    case "$1" in
        [A-Z])
            n=$(printf "%d" "'$1")
            n=$((n+32))
            printf \\$(printf "%o" "$n")
            ;;
        *)
            printf "%s" "$1"
            ;;
    esac
}

# Prints the lowercase version of a sequence of strings
lowercase() {
    word="$@"
    for((i=0;i<${#word};i++)); do
        ch="${word:$i:1}"
        lowercaseChar "$ch"
    done
}

# Prints the uppercase version of a char
uppercaseChar(){
    case "$1" in
        [a-z])
            n=$(printf "%d" "'$1")
            n=$((n-32))
            printf \\$(printf "%o" "$n")
            ;;
        *)
            printf "%s" "$1"
            ;;
    esac
}

# Prints the uppercase version of a sequence of strings
uppercase() {
    word="$@"
    for((i=0;i<${#word};i++)); do
        ch="${word:$i:1}"
        uppercaseChar "$ch"
    done
}

# The functions will not add a new line, so use echo or
# append it if you want a new line after printing

# Printing stuff directly
lowercase "I AM the Walrus!"$'\n'
uppercase "I AM the Walrus!"$'\n'

echo "----------"

# Printing a var
str="A StRing WITH mixed sTUFF!"
lowercase "$str"$'\n'
uppercase "$str"$'\n'

echo "----------"

# Not quoting the var should also work, 
# since we use "$@" inside the functions
lowercase $str$'\n'
uppercase $str$'\n'

echo "----------"

# Assigning to a var
myLowerVar="$(lowercase $str)"
myUpperVar="$(uppercase $str)"
echo "myLowerVar: $myLowerVar"
echo "myUpperVar: $myUpperVar"

echo "----------"

# You can even do stuff like
if [[ 'option 2' = "$(lowercase 'OPTION 2')" ]]; then
    echo "Fine! All the same!"
else
    echo "Ops! Not the same!"
fi

exit 0

And the results after running this:

$ ./lowerupper.sh 
i am the walrus!
I AM THE WALRUS!
----------
a string with mixed stuff!
A STRING WITH MIXED STUFF!
----------
a string with mixed stuff!
A STRING WITH MIXED STUFF!
----------
myLowerVar: a string with mixed stuff!
myUpperVar: A STRING WITH MIXED STUFF!
----------
Fine! All the same!

This should only work for ASCII characters though.

For me it is fine, since I know I will only pass ASCII chars to it.
I am using this for some case-insensitive CLI options, for example.

Adding on to superM's and Jeff's answer,

If there are 2 views in the LinearLayout, the first with a layout_weight of 1, the second with a layout_weight of 2 and no weightSum is specified, by default, the weightSum is calculated to be 3 (sum of the weights of the children) and the first view takes 1/3 of the space while the second takes 2/3.

However, if we were to specify the weightSum as 5, the first would take 1/5th of the space while the second would take 2/5th. So a total of 3/5th of the space would be occupied by the layout keeping the rest empty.

SELECT DATEADD (DAY, -1 * (DAY(GETDATE()) - 1), GETDATE())

.....................................................................

If you dont want the time, then convert it to DATE or if want to make to time to 0:00:00, Convert to DATE and then back to DATETIME.

SELECT CONVERT (DATETIME,  
CONVERT (DATE, DATEADD (DAY, -1 * (DAY(GETDATE()) - 1),
GETDATE())))

Change GETDATE() to the date you want

^(-+)?[1-9][0-9]*$ starts with a - or + for 0 or 1 times, then you want a non zero number (because there is not such a thing -0 or +0) and then it continues with any number from 0 to 9

I know this is old, but i think i have good solution. Comparing to other answers and also comparing to accepted, mine accepts multiple values. Basically filter object with key:value search parameters (also object within object). Also it works with numbers etc, cause when comparing, it converts them to string.

parseInt(string) will convert a string containing non-numeric characters to a number, as long as the string begins with numeric characters

'10px' => 10

Number(string) will return NaN if the string contains any non-numeric characters

'10px' => NaN

It might be the JavaScript check for some valid condition.
Two things you can perform a/c to your requirements:

1. either check for the valid string-input in the text-box.
2. or set a loop against that text box to enter the value until you post the form/request.

String barcode="0000000047166";

WebElement strLocator = driver.findElement(By.xpath("//*[@id='div-barcode']"));
strLocator.sendKeys(barcode);

In your example, a refers first to "a", and then to "ty". You're not mutating any String instance; you're just changing which String instance a refers to. For example, this:

String a = "a";
String b = a; // b refers to the same String as a
a = "b"; // a now refers to a different instance
System.out.println(b);

prints "a", because we never mutate the String instance that b points to.

Addition:

When using the MySQL client library, then you should prevent a conversion back to your connection's default charset. (see mysql_set_character_set()[1])

In this case, use an additional cast to binary:

SELECT column1, CAST(CONVERT(column2 USING utf8) AS binary)
FROM my_table
WHERE my_condition;

Otherwise, the SELECT statement converts to utf-8, but your client library converts it back to a (potentially different) default connection charset.

This is very good: http://simononsoftware.com/virtualenv-tutorial-part-2/

And this is a slightly more practical one: https://web.archive.org/web/20160404222648/https://iamzed.com/2009/05/07/a-primer-on-virtualenv/

Vim's <leader> key is a way of creating a namespace for commands you want to define. Vim already maps most keys and combinations of Ctrl + (some key), so <leader>(some key) is where you (or plugins) can add custom behavior.

For example, if you find yourself frequently deleting exactly 3 words and 7 characters, you might find it convenient to map a command via nmap <leader>d 3dw7x so that pressing the leader key followed by d will delete 3 words and 7 characters. Because it uses the leader key as a prefix, you can be (relatively) assured that you're not stomping on any pre-existing behavior.

The default key for <leader> is \, but you can use the command :let mapleader = "," to remap it to another key (, in this case).

Usevim's page on the leader key has more information.

The problem is that you are trying to insert data into the database without using columns. Sql server gives you that error message.

error: insert into users values('1', '2','3') - this works fine as long you only have 3 columns

if you have 4 columns but only want to insert into 3 of them

correct: insert into users (firstName,lastName,city) values ('Tom', 'Jones', 'Miami')

hope this helps

I am impressed with this one:

http://www.computerhope.com/batch.htm#02

choice /n /c y /d y /t 5 > NUL

Technically, you're telling the choice command to accept only y. It defaults to y, to do so in 5 seconds, to draw no prompt, and to dump anything it does say to NUL (like null terminal on Linux).

Disabled is a Boolean Attribute of the select element as stated by WHATWG, that means the RIGHT WAY TO DISABLE with jQuery would be

jQuery("#selectId").attr('disabled',true);

This would make this HTML

<select id="selectId" name="gender" disabled="disabled">
    <option value="-1">--Select a Gender--</option>
    <option value="0">Male</option>
    <option value="1">Female</option>
</select>

This works for both XHTML and HTML (W3School reference)

Yet it also can be done using it as property

jQuery("#selectId").prop('disabled', 'disabled');

getting

<select id="selectId" name="gender" disabled>

Which only works for HTML and not XTML

NOTE: A disabled element will not be submitted with the form as answered in this question: The disabled form element is not submitted

NOTE2: A disabled element may be greyed out.

NOTE3:

A form control that is disabled must prevent any click events that are queued on the user interaction task source from being dispatched on the element.

TL;DR

<script>
    var update_pizza = function () {
        if ($("#pizza").is(":checked")) {
            $('#pizza_kind').attr('disabled', false);
        } else {
            $('#pizza_kind').attr('disabled', true);
        }
    };
    $(update_pizza);
    $("#pizza").change(update_pizza);
</script>

The "uni" in unistd stands for "UNIX" - you won't find it on a Windows system.

Most widely used, portable libraries should offer alternative builds or detect the platform and only try to use headers/functions that will be provided, so it's worth checking documentation to see if you've missed some build step - e.g. perhaps running "make" instead of loading a ".sln" Visual C++ solution file.

If you need to fix it yourself, remove the include and see which functions are actually needed, then try to find a Windows equivalent.

Wrap the task in FutureTask and you can specify timeout for the FutureTask. Look at the example in my answer to this question,

Unless you try to extend the Android CardView class, you cannot customize that attribute from XML.

Nonetheless, there is a way of obtaining that effect.

Place a CardView inside another CardView and apply a transparent background to your outer CardView and remove its corner radius ("cornerRadios = 0dp"). Your inner CardView will have a cornerRadius value of 3dp, for example. Then apply a marginTop to your inner CardView, so its bottom bounds will be cut by the outer CardView. This way, the bottom corner radius of your inner CardView will be hidden.

The XML code is the following:

 <android.support.v7.widget.CardView
    xmlns:card_view="http://schemas.android.com/apk/res-auto"
    android:id="@+id/card_view_outer"
    android:layout_width="match_parent"
    android:layout_height="200dp"
    android:layout_gravity="center"
    card_view:cardBackgroundColor="@android:color/transparent"
    card_view:cardCornerRadius="0dp"
    card_view:cardElevation="3dp" >

    <android.support.v7.widget.CardView
        xmlns:card_view="http://schemas.android.com/apk/res-auto"
        android:id="@+id/card_view_inner"
        android:layout_width="match_parent"
        android:layout_height="200dp"
        android:layout_gravity="center"
        android:layout_marginTop="3dp"
        card_view:cardBackgroundColor="@color/green"
        card_view:cardCornerRadius="4dp"
        card_view:cardElevation="0dp" >
    </android.support.v7.widget.CardView>
</android.support.v7.widget.CardView>

And the visual effect is the following:

Always put your content in your Inner CardView. Your outer CardView serves only the purpose of "hiding" the bottom Rounded Corners of the inner CardView.

You can go to jwt.io, paste your token and read the contents. This is jarring for a lot of people initially.

The short answer is that JWT doesn't concern itself with encryption. It cares about validation. That is to say, it can always get the answer for "Have the contents of this token been manipulated"? This means user manipulation of the JWT token is futile because the server will know and disregard the token. The server adds a signature based on the payload when issuing a token to the client. Later on it verifies the payload and matching signature.

The logical question is what is the motivation for not concerning itself with encrypted contents?

1. The simplest reason is because it assumes this is a solved problem for the most part. If dealing with a client like the web browser for example, you can store the JWT tokens in a cookie that is secure (is not transmitted via HTTP, only via HTTPS) and httpOnly (can't be read by Javascript) and talks to the server over an encrypted channel (HTTPS). Once you know you have a secure channel between the server and client you can securely exchange JWT or whatever else you want.

2. This keeps thing simple. A simple implementation makes adoption easier but it also lets each layer do what it does best (let HTTPS handle encryption).

3. JWT isn't meant to store sensitive data. Once the server receives the JWT token and validates it, it is free to lookup the user ID in its own database for additional information for that user (like permissions, postal address, etc). This keeps JWT small in size and avoids inadvertent information leakage because everyone knows not to keep sensitive data in JWT.

It's not too different from how cookies themselves work. Cookies often contain unencrypted payloads. If you are using HTTPS then everything is good. If you aren't then it's advisable to encrypt sensitive cookies themselves. Not doing so will mean that a man-in-the-middle attack is possible--a proxy server or ISP reads the cookies and then replays them later on pretending to be you. For similar reasons, JWT should always be exchanged over a secure layer like HTTPS.

I find the STR function the cleanest means of accomplishing this.

SELECT STR(ceiling(123.415432875), 6, 2)

$(document).ready( function() { YOUR CODE HERE } )

To my understanding - we do not declare a variable with a data type so by default R has set any number without L to be a numeric. If you wrote:

> x <- c(4L, 5L, 6L, 6L)
> class(x)
>"integer" #it would be correct

Example of Integer:

> x<- 2L
> print(x)

Example of Numeric (kind of like double/float from other programming languages)

> x<-3.4
> print(x)

It will be something like:

R.drawable.resourcename

Make sure you don't have the Android.R namespace imported as it can confuse Eclipse (if that's what you're using).

If that doesn't work, you can always use a context's getResources method ...

Drawable resImg = this.context.getResources().getDrawable(R.drawable.resource);

Where this.context is intialised as an Activity, Service or any other Context subclass.

Update:

If it's the name you want, the Resources class (returned by getResources()) has a getResourceName(int) method, and a getResourceTypeName(int)?

Update 2:

The Resources class has this method:

public int getIdentifier (String name, String defType, String defPackage) 

Which returns the integer of the specified resource name, type & package.

you should have three tables: users, comments and comment_users.

comment_users has just two fields: fk_user_id and fk_comment_id

That way you can keep your performance up to a maximum :)

You can convert that time in Unix timestamp by using

select UNIX_TIMESTAMP('2013-11-26 01:24:34')

then convert it in the readable format in whatever format you need

select from_unixtime(UNIX_TIMESTAMP('2013-11-26 01:24:34'),"%Y-%m-%d");

You can use GNU awk:

$ cat hta
RewriteCond %{HTTP_HOST} !^www\.mysite\.net$
RewriteRule (.*) http://www.mysite.net/$1 [R=301,L]

$ gawk 'match($0, /.*(http.*?)\$/, m) { print m[1]; }' < hta

To clarify, a database created under SQL Server 2008 R2 was being opened in an instance of SQL Server 2008 (the version prior to R2). The solution for me was to simply perform an upgrade installation of SQL Server 2008 R2. I can only speak for the Express edition, but it worked.

Oddly, though, the Web Platform Installer indicated that I had Express R2 installed. The better way to tell is to ask the database server itself:

SELECT @@VERSION

This should do the trick!

// convert object => json
$json = json_encode($myObject);

// convert json => object
$obj = json_decode($json);

Here's an example

$foo = new StdClass();
$foo->hello = "world";
$foo->bar = "baz";

$json = json_encode($foo);
echo $json;
//=> {"hello":"world","bar":"baz"}

print_r(json_decode($json));
// stdClass Object
// (
//   [hello] => world
//   [bar] => baz
// )

If you want the output as an Array instead of an Object, pass true to json_decode

print_r(json_decode($json, true));
// Array
// (
//   [hello] => world
//   [bar] => baz
// )

For Scala 2.11, if getLines doesn't do exactly what you want you can also copy the a file out of the jar to the local file system.

Here's a snippit that reads a binary google .p12 format API key from /resources, writes it to /tmp, and then uses the file path string as an input to a spark-google-spreadsheets write.

In the world of sbt-native-packager and sbt-assembly, copying to local is also useful with scalatest binary file tests. Just pop them out of resources to local, run the tests, and then delete.

import java.io.{File, FileOutputStream}
import java.nio.file.{Files, Paths}

def resourceToLocal(resourcePath: String) = {

Try this:

First, you declared $db outside the function. If you want to use it inside the function, you should put this at the begining of your function code:

global $db;

And I guess, when you wrote:

if($result->num_rows){
        return (mysqli_result($query, 0) == 1) ? true : false;

what you really wanted was:

if ($result->num_rows==1) { return true; } else { return false; }

A StaticResource will be resolved and assigned to the property during the loading of the XAML which occurs before the application is actually run. It will only be assigned once and any changes to resource dictionary ignored.

A DynamicResource assigns an Expression object to the property during loading but does not actually lookup the resource until runtime when the Expression object is asked for the value. This defers looking up the resource until it is needed at runtime. A good example would be a forward reference to a resource defined later on in the XAML. Another example is a resource that will not even exist until runtime. It will update the target if the source resource dictionary is changed.

My resolution was kind of stupid.

• I installed a copy of .net 3.5

• Created another app pool and selected .net 3.5 (it says 2.0.5077 in the drop down)

• Added my website to that app pool

• Recycled the old and new pools and the site started working.

It came down to me not having 3.5 installed even though the turn on windows features said I did and creating another app pool to use. I hope this helps others.

"Commercial use" in cases like this is actually just a shorthand to indicate that the product is dual-licensed under both an open source and a traditional paid-for commercial license.

Any "true" open source license will not discriminate against commercial use. (See clause 6 of the Open Source Definition.) However, open source licenses like the GPL contain clauses that are incompatible with most companies' approach to commercial software (since the GPL requires that you make your source code available if you incorporate GPL'ed code into your product).

Duel-licensing is a way to accommodate this and also provides a revenue stream for the company providing the software. For users that don't mind the restrictions of the GPL and don't need support, the product is available under an open source license. For users for whom the GPL's restrictions would be incompatible with their business model, and for users that do need support, a commercial license is available.

You gave the specific example of the Screwturn wiki, which is dual-licensed under the GPL and a commercial license. Under the terms of the GPL (i.e., without getting a "commercial" license), you can do the following:

• Use it internally as much as you want (see here)
• Run it on your internal servers for external users / clients / customers, or run it on your internal servers for paying clients if you're an ISP / hosting provider. (If Screwturn were licensed under the AGPL instead of the GPL, that might restrict this.)
• Distribute it to others, either free of charge or for a payment that covers the shipping, as long as you're willing to also distribute the source code
• Incorporate it into your product, as long as you're willing to also distribute the source code, and as long as either (a) it remains a separate program that you merely aggregate with your product or (b) you release the source code to your product under an open source license compatible with the GPL

In other words, there's a lot that you can do without getting a commercial license. This is especially true for web-based software, since people can use web-based software without it being distributed to them. Screwturn's web site even acknowledges this: they state that the commercial license is for "either integrating it in a commercial application, or using it in an enterprise environment where free software is not allowed," not for any use related to commerce.

All of the preceding is merely my understanding and is not intended to be legal advice. Consult your lawyer to be certain.

This is a simple way to do it without any triggers or sequences:

insert into WORKQUEUE (ID, facilitycode, workaction, description)
  values ((select max(ID)+1 from WORKQUEUE), 'J', 'II', 'TESTVALUES')

It worked for me but would not work with an empty table, I guess.

You can not check for version support via command line. Best option would be checking OpenSSL changelog.

Openssl versions till 1.0.0h supports SSLv2, SSLv3 and TLSv1.0. From Openssl 1.0.1 onward support for TLSv1.1 and TLSv1.2 is added.

Alternatively (I'd say preferably), you can do it like this:

$(function () {
  $("div.class, div.secondclass").click(function(){
    //Doo something
  });
});

You can try this as well:

from time import perf_counter

t0 = perf_counter()

...

t1 = perf_counter()
time_taken = t1 - t0

Comprehensive answer is here: https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/putty.html

Your problem can be related to incorrect login which varies depending on AMIs. Use following logins on following AMIs:

• ubuntu or root on ubuntu AMIs
• ec2-user on Amazon Linux AMI
• centos on Centos AMI
• debian or root on Debian AMIs
• ec2-user or fedora on Fedora
• ec2-user or root on: RHEL AMI, SUSE AMI, other ones.

If you are using OS:

• Windows - get PEM key from AWS website and generate PPK file using PuttyGen. Then use Putty to use the PPK (select it using left-column: Connection->SSH->Auth: Private key for authorization)
• Linux - run: ssh -i your-ssh-key.pem login@IP-or-DNS

Good luck.

You probably want

SELECT sum(bytes)
  FROM dba_segments
 WHERE owner = <<owner of schema>>

If you are logged in as the schema owner, you can also

SELECT SUM(bytes)
  FROM user_segments

That will give you the space allocated to the objects owned by the user in whatever tablespaces they are in. There may be empty space allocated to the tables that is counted as allocated by these queries.

defaultMember already is an alias - it doesn't need to be the name of the exported function/thing. Just do

import alias from 'my-module';

Alternatively you can do

import {default as alias} from 'my-module';

but that's rather esoteric.

In summary, the most reliable way to have MiniDLNA rescan all media files is by issuing the following set of commands:

$ sudo minidlnad -R
$ sudo service minidlna restart

Client-side script to rescan server

However, every so often MiniDLNA will be running on a server. Here is a client-side script to request a rescan on such a server:

#!/usr/bin/env bash
ssh -t server.on.lan 'sudo minidlnad -R && sudo service minidlna restart'

This is great!

You could simply use the modulo operation (MOD or % in mysql) to make your code simple at the end:

Instead of:

AND (
    ( CASE ( 1299132000 - EM1.`meta_value` )
        WHEN 0
          THEN 1
        ELSE ( 1299132000 - EM1.`meta_value` )
      END
    ) / EM2.`meta_value`
) = 1

Do:

$current_timestamp = 1299132000 ;

AND ( ('$current_timestamp' - EM1.`meta_value` ) MOD EM2.`meta_value`) = 1")

To take this further, one could include events that do not recur for ever.

Something like "repeat_interval_1_end" to denote the date of the last "repeat_interval_1" could be added. This however, makes the query more complicated and I can't really figure out how to do this ...

Maybe someone could help!

To center the div on a page, check the fiddle link.

#vh {_x000D_
    margin: auto;_x000D_
    position: absolute;_x000D_
    top: 0;_x000D_
    left: 0;_x000D_
    bottom: 0;_x000D_
    right: 0;_x000D_
}_x000D_
.box{_x000D_
    border-radius: 15px;_x000D_
    box-shadow: 0 0 8px rgba(0, 0, 0, 0.4);_x000D_
    padding: 25px;_x000D_
    width: 100px;_x000D_
    height: 100px;_x000D_
    background: white;_x000D_
}

<div id="vh" class="box">Div to be aligned vertically</div>

Another option is to use flex box, check the fiddle link.

.vh {_x000D_
    background-color: #ddd;_x000D_
    height: 400px;_x000D_
    align-items: center;_x000D_
    display: flex;_x000D_
}_x000D_
.vh > div {_x000D_
    width: 100%;_x000D_
    text-align: center;_x000D_
    vertical-align: middle;_x000D_
}

<div class="vh">_x000D_
    <div>Div to be aligned vertically</div>_x000D_
</div>

Another option is to use a CSS 3 transform:

#vh {_x000D_
    position: absolute;_x000D_
    top: 50%;_x000D_
    left: 50%;_x000D_
    /*transform: translateX(-50%) translateY(-50%);*/_x000D_
    transform: translate(-50%, -50%);_x000D_
}_x000D_
.box{_x000D_
    border-radius: 15px;_x000D_
    box-shadow: 0 0 8px rgba(0, 0, 0, 0.4);_x000D_
    padding: 25px;_x000D_
    width: 100px;_x000D_
    height: 100px;_x000D_
    background: white;_x000D_
}

<div id="vh" class="box">Div to be aligned vertically</div>

I have met the same problem as I install it globally, then I try to install it locally, and it work.

You can try this.

txt = <file_path>
txt_opn = open(txt)
print txt_opn.read()

This will give you file output.

We use Maven (Ant's big brother) for all our java projects, and it has a very nifty WAR plugin. Tutorials and usage can be found there.

It's a lot easier than Ant, fully compatible with Eclipse (use maven eclipse:eclipse to create Eclipse projects) and easy to configure.

It should be "datepicker", not "datePicker" if you are using the jQuery UI DatePicker plugin. Perhaps, you have a different but similar plugin that doesn't support the select handler.

Since **kwargs is used when the number of arguments is unknown, why not doing this?

class Exampleclass(object):
  def __init__(self, **kwargs):
    for k in kwargs.keys():
       if k in [acceptable_keys_list]:
          self.__setattr__(k, kwargs[k])

<div ng-controller="ExampleController">
  <form name="myForm">
    <label for="repeatSelect"> Repeat select: </label>
    <select name="repeatSelect" id="repeatSelect" ng-model="data.model">
      <option ng-repeat="option in data.availableOptions" value="{{option.id}}">{{option.name}}</option>
    </select>
  </form>
  <hr>
  <tt>model = {{data.model}}</tt><br/>
</div>

AngularJS:

angular.module('ngrepeatSelect', [])
 .controller('ExampleController', ['$scope', function($scope) {
   $scope.data = {
    model: null,
    availableOptions: [
      {id: '1', name: 'Option A'},
      {id: '2', name: 'Option B'},
      {id: '3', name: 'Option C'}
    ]
   };

After studying the Internet for a day I found my own solution for selecting an item after create a normal treeview in a normal WPF/C# environment

private void BuildSortTree(int sel)
        {
            MergeSort.Items.Clear();
            TreeViewItem itTemp = new TreeViewItem();
            itTemp.Header = SortList[0];
            MergeSort.Items.Add(itTemp);
            TreeViewItem prev;
            itTemp.IsExpanded = true;
            if (0 == sel) itTemp.IsSelected= true;
            prev = itTemp;
            for(int i = 1; i<SortList.Count; i++)
            {

                TreeViewItem itTempNEW = new TreeViewItem();
                itTempNEW.Header = SortList[i];
                prev.Items.Add(itTempNEW);
                itTempNEW.IsExpanded = true;
                if (i == sel) itTempNEW.IsSelected = true;
                prev = itTempNEW ;
            }
        }

You need to wrap your your rows in <thead> for the column headers and <tbody> for the rows. Also ensure that you have matching no. of column headers <th> as you do for the td

This was previously asked on R-Help, so that's worth reviewing.

One suggestion there was to use readChar() and then do string manipulation on the result with strsplit() and substr(). You can see the logic involved in readChar is much less than read.table.

I don't know if memory is an issue here, but you might also want to take a look at the HadoopStreaming package. This uses Hadoop, which is a MapReduce framework designed for dealing with large data sets. For this, you would use the hsTableReader function. This is an example (but it has a learning curve to learn Hadoop):

str <- "key1\t3.9\nkey1\t8.9\nkey1\t1.2\nkey1\t3.9\nkey1\t8.9\nkey1\t1.2\nkey2\t9.9\nkey2\"
cat(str)
cols = list(key='',val=0)
con <- textConnection(str, open = "r")
hsTableReader(con,cols,chunkSize=6,FUN=print,ignoreKey=TRUE)
close(con)

The basic idea here is to break the data import into chunks. You could even go so far as to use one of the parallel frameworks (e.g. snow) and run the data import in parallel by segmenting the file, but most likely for large data sets that won't help since you will run into memory constraints, which is why map-reduce is a better approach.

Also when I hit the post(Config.getURL("login"), values) the app seems to pause for a while (seems weird - thought the idea behind a service was that it runs on a different thread!)

In this case its better to use asynctask, which runs on a different thread and return result back to the ui thread on completion.

I'm not sure how necessary this is, and it adds a call to getElementById, but if you're really keen on getting inline JavaScript out of your code, you can pass it as an HTML attribute, namely:

<span class="metadata" id="metadata-size-of-widget" title="<?php echo json_encode($size_of_widget) ?>"></span>

And then in your JavaScript:

var size_of_widget = document.getElementById("metadata-size-of-widget").title;

Here is another option:

Task.Run(()=>{
//Here is a new thread
});

I would say that a scrollBottom as a direct opposite of scrollTop should be:

var scrollBottom = $(document).height() - $(window).height() - $(window).scrollTop();

Here is a small ugly test that works for me:

// SCROLLTESTER START //
$('<h1 id="st" style="position: fixed; right: 25px; bottom: 25px;"></h1>').insertAfter('body');

$(window).scroll(function () {
  var st = $(window).scrollTop();
  var scrollBottom = $(document).height() - $(window).height() - $(window).scrollTop();

  $('#st').replaceWith('<h1 id="st" style="position: fixed; right: 25px; bottom: 25px;">scrollTop: ' + st + '<br>scrollBottom: ' + scrollBottom + '</h1>');
});
// SCROLLTESTER END //

I faced the same issue of Firebase cloud messaging not received by device.

In my case package name defined on Firebase Console Project was diferent than that the one defined on Manifest & Gradle of my Android Project.

As a result I received token correctly but no messages at all.

To sumarize, it's mandatory that Firebase Console package name and Manifest & Gradle matchs.

You must also keep in mind that to receive Messages sent from Firebase Console, App must be in background, not started neither hidden.

What about this. Seems to give better performance.

byte[] bytes = new byte[1000];

StringBuilder x = new StringBuilder();

int numRead = 0;
while ((numRead = is.read(bytes)) >= 0) {
    x.append(new String(bytes, 0, numRead));
}

Edit: Actually this sort of encompasses both steelbytes and Maurice Perry's

I accomplished this by creating a ::before selector for the first inline element in the row, and making that selector a block with a top or bottom margin to separate rows a little bit.

.1st_item::before
{
  content:"";
  display:block;
  margin-top: 5px;
}

.1st_item
{
  color:orange;
  font-weight: bold;
  margin-right: 1em;
}

.2nd_item
{
  color: blue;
}

I believe you can diff against files in your index and untracked files by simply supplying the path to both files.

git diff --no-index tracked_file untracked_file

Here is the simplest way to do it with CSS3:

#mybox:hover {
  color: transparent;
}

regardless of the container color you can make the text color transparent on hover.

The lock screen works without keyguard i have tested it. The home button stops working and you can't get to task manager by holding the home key. I wish they didn't develop a new process when it used to be built into system ui or whatever. I don't see the need for the change and extra process

Initialize instance:

private String imagePath;
private List<String> imagePathList;

In onActivityResult You have to write this, If-else 2 block. One for single image and another for multiple image.

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

    imagePathList = new ArrayList<>();

    if(data.getClipData() != null){

        int count = data.getClipData().getItemCount();
        for (int i=0; i<count; i++){

            Uri imageUri = data.getClipData().getItemAt(i).getUri();
            getImageFilePath(imageUri);
        }
    }
    else if(data.getData() != null){

        Uri imgUri = data.getData();
        getImageFilePath(imgUri);
    }

public void getImageFilePath(Uri uri) {

    File file = new File(uri.getPath());
    String[] filePath = file.getPath().split(":");
    String image_id = filePath[filePath.length - 1];

    Cursor cursor = getContentResolver().query(android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI, null, MediaStore.Images.Media._ID + " = ? ", new String[]{image_id}, null);
    if (cursor!=null) {
        cursor.moveToFirst();
        imagePath = cursor.getString(cursor.getColumnIndex(MediaStore.Images.Media.DATA));
        imagePathList.add(imagePath);
        cursor.close();
    }
}

Hope this can help you.

Yes, Python does support Short-circuit evaluation, minimal evaluation, or McCarthy evaluation for Boolean operators. It is used to reduce the number of evaluations for computing the output of boolean expression. Example -

Base Functions

def a(x):
    print('a')
    return x

def b(x):
    print('b')
    return x 

AND

if(a(True) and b(True)):
    print(1,end='\n\n')

if(a(False) and b(True)):
    print(2,end='\n\n') 

AND-OUTPUT

a
b
1

a 

OR

if(a(True) or b(False)):
    print(3,end='\n\n')

if(a(False) or b(True)):
    print(4,end='\n\n') 

OR-OUTPUT

a
3

a
b
4 

Add a type to your variable and then return.

Eg:

const myVariable : string [] = ['hello', 'there'];

const result = myVaraible.map(x=> {
  return
  {
    x.id
  }
});

=> Important part is adding the string[] type etc:

You should probably use SQL_Latin1_General_Cp1_CI_AS_KI_WI as your collation. The one you specify in your question is explictly case sensitive.

You can see a list of collations here.

abs() : Returns the absolute value as per the argument i.e. if argument is int then it returns int, if argument is float it returns float. Also it works on complex variable also i.e. abs(a+bj) also works and returns absolute value i.e.math.sqrt(((a)**2)+((b)**2)

math.fabs() : It only works on the integer or float values. Always returns the absolute float value no matter what is the argument type(except for the complex numbers).

This might be the simplest you can get:

function text2Binary(string) {
    return string.split('').map(function (char) {
        return char.charCodeAt(0).toString(2);
    }).join(' ');
}

Using GNU parallel (sudo apt install parallel) is super easy

It runs the commands multithreaded where '{}' is the argument passed

E.g.

ls /tmp/myfiles* | parallel 'rm {}'

The oneliner:

open("out1.txt", "w").writelines([l for l in open("in.txt").readlines() if "tests/file/myword" in l])

Recommended with with:

with open("in.txt") as f:
    lines = f.readlines()
    lines = [l for l in lines if "ROW" in l]
    with open("out.txt", "w") as f1:
        f1.writelines(lines)

Using less memory:

with open("in.txt") as f:
    with open("out.txt", "w") as f1:
        for line in f:
            if "ROW" in line:
                f1.write(line) 

If you are using Bootstrap, you can do it directly with bootstrap way via dropdowns (Bootstrap component).

<div class="input-group">
    <div class="input-group-btn">
        <button aria-expanded="false" aria-haspopup="true" class="btn btn-default dropdown-toggle" data-toggle="dropdown" type="button">
            Toggle Drop Down. <span class="fa fa-sort-alpha-asc"></span>
        </button>
        <ul class="dropdown-menu">
            <li>List 1</li>
            <li>List 2</li>
            <li>List 3</li>
        </ul>
    </div>
</div>

Now it's OK to put (click)="clickButton()" stuff on the button. http://getbootstrap.com/javascript/#dropdowns

If you aren't comfortable with using negative margins, check this out.

div {
  position: fixed;
  left: 50%;
  bottom: 20px;
  transform: translate(-50%, -50%);
  margin: 0 auto;
}

<div>
  Your Text
</div>

Especially useful when you don't know the width of the div.

align="center" has no effect.

Since you have position:absolute, I would recommend positioning it 50% from the left and then subtracting half of its width from its left margin.

#manipulate {
    position:absolute;
    width:300px;
    height:300px;
    background:#063;
    bottom:0px;
    right:25%;
    left:50%;
    margin-left:-150px;
}

If you do a lot of this sort of thing then it might be worth defining the function for yourself.

if (typeof NodeList.prototype.forEach == "undefined"){
    NodeList.prototype.forEach = function (cb){
        for (var i=0; i < this.length; i++) {
            var node = this[i];
            cb( node, i );
        }
    };
}

By using the Nuget Package Manager UI as mentioned above it helps to uninstall the nuget package first. I always have problems when going back on a nuget package version if I don't uninstall first. Some references are not cleaned properly. So I suggest the following workflow when installing an old nuget package through the Nuget Package Manager:

1. Selected your nuget server / source
2. Find and select the nuget package your want to install an older version
3. Uninstall current version
4. Click on the install drop-down > Select older version > Click Install

Good Luck :)

MySQL 4.1 and above has a default character set that it calls utf8 but which is actually only a subset of UTF-8 (allows only three-byte characters and smaller).

Use utf8mb4 as your charset if you want "full" UTF-8.

I saw this question a lot when I worked for an address verification company. I'm posting the answer here to make it more accessible to programmers searching around with the same question. The company I was at processed billions of addresses, and we learned a lot in the process.

First, we need to understand a few things about addresses.

Addresses are not regular

This means that regular expressions are out. I've seen it all, from simple regular expressions that match addresses in a very specific format, to this:

/\s+(\d{2,5}\s+)(?![a|p]m\b)(([a-zA-Z|\s+]{1,5}){1,2})?([\s|,|.]+)?(([a-zA-Z|\s+]{1,30}){1,4})(court|ct|street|st|drive|dr|lane|ln|road|rd|blvd)([\s|,|.|;]+)?(([a-zA-Z|\s+]{1,30}){1,2})([\s|,|.]+)?\b(AK|AL|AR|AZ|CA|CO|CT|DC|DE|FL|GA|GU|HI|IA|ID|IL|IN|KS|KY|LA|MA|MD|ME|MI|MN|MO|MS|MT|NC|ND|NE|NH|NJ|NM|NV|NY|OH|OK|OR|PA|RI|SC|SD|TN|TX|UT|VA|VI|VT|WA|WI|WV|WY)([\s|,|.]+)?(\s+\d{5})?([\s|,|.]+)/i

... to this where a 900+ line-class file generates a supermassive regular expression on the fly to match even more. I don't recommend these (for example, here's a fiddle of the above regex, that makes plenty of mistakes). There isn't an easy magic formula to get this to work. In theory and by theory, it's impossible to match addresses with a regular expression.

USPS Publication 28 documents the many formats of addresses that are possible, with all their keywords and variations. Worst of all, addresses are often ambiguous. Words can mean more than one thing ("St" can be "Saint" or "Street"), and there are words that I'm pretty sure they invented. (Who knew that "Stravenue" was a street suffix?)

You'd need some code that really understands addresses, and if that code does exist, it's a trade secret. But you could probably roll your own if you're really into that.

Addresses come in unexpected shapes and sizes

Here are some contrived (but complete) addresses:

1)  102 main street
    Anytown, state

2)  400n 600e #2, 52173

3)  p.o. #104 60203

Even these are possibly valid:

4)  829 LKSDFJlkjsdflkjsdljf Bkpw 12345

5)  205 1105 14 90210

Obviously, these are not standardized. Punctuation and line break are not guaranteed. Here's what's going on:

1. Number 1 is complete because it contains a street address and a city and state. With that information, there's enough to identify the address, and it can be considered "deliverable" (with some standardization).

2. Number 2 is complete because it contains a street address (with secondary/unit number) and a 5-digit ZIP code, which is enough to identify an address.

3. Number 3 is a complete post office box format, as it contains a ZIP code.

4. Number 4 is also complete because the ZIP code is unique, meaning that a private entity or corporation has purchased that address space. A unique ZIP code is for high-volume or concentrated delivery spaces. Anything addressed to ZIP code 12345 goes to General Electric in Schenectady, NY. This example won't reach anyone in particular, but the USPS would still deliver it.

5. Number 5 is also complete, believe it or not. With just those numbers, the full address can be discovered when parsed against a database of all possible addresses. Filling in the missing directionals, secondary designator, and ZIP+4 code is trivial when you see each number as a component. Here's what it looks like, fully expanded and standardized:

205 N 1105 W Apt 14

Beverly Hills CA 90210-5221

Address data is not your own

In most countries that provide official address data to licensed vendors, the address data itself belongs to the governing agency. In the US, the USPS owns the addresses. The same is true for Canada Post, Royal Mail, and others, though each country enforces or defines ownership a little differently. Knowing this is important since it usually forbids reverse-engineering the address database. You have to be careful how to acquire, store, and use the data.

Google Maps is a common go-to for quick address fixes, but the TOS is rather prohibitive; for example, you can't use their data or APIs without showing a Google Map, and for non-commercial purposes only (unless you pay), and you can't store the data (except for temporary caching). Makes sense. Google's data is some of the best in the world. However, Google Maps does not verify the address. If an address does not exist, it will still show you where the address would be if it did exist (try it on your own street; use a house number that you know doesn't exist). This is useful sometimes, but be aware of that.

Nominatim's usage policy is similarly limiting, especially for high volume and commercial use, and the data is mostly drawn from free sources, so it isn't as well maintained (such as the nature of open projects). However, this may still suit your needs. A great community supports it.

The USPS itself has an API, but it goes down a lot and comes with no guarantees nor support. It might also be hard to use. Some people use it sparingly with no problems. But it's easy to miss that the USPS requires that you use their API only for confirming addresses to ship through them.

People expect addresses to be hard

Unfortunately, we've conditioned our society to expect addresses to be complicated. There are dozens of good UX articles all over the Internet about this. Still, the fact is, if you have an address form with individual fields, that's what users expect, even though it makes it harder for edge-case addresses that don't fit the format the form is expecting, or maybe the form requires a field it shouldn't. Or users don't know where to put a certain part of their address.

I could go on and on about the bad UX of checkout forms these days, but instead, I'll say that combining the addresses into a single field will be a welcome change -- people will be able to type their address how they see fit, rather than trying to figure out your lengthy form. However, this change will be unexpected and users may find it a little jarring at first. Just be aware of that.

Part of this pain can be alleviated by putting the country field out front, before the address. When they fill out the country field first, you know how to make your form appear. Maybe you have a good way to deal with single-field US addresses, so if they select the United States, you can reduce your form to a single field, otherwise show the component fields. Just things to think about!

Now we know why it's hard; what can you do about it?

The USPS licenses vendors through a process called CASS™ Certification to provide verified addresses to customers. These vendors have access to the USPS database, updated monthly. Their software must conform to rigorous standards to be certified, and they don't often require agreement to such limiting terms as discussed above.

Many CASS-Certified companies can process lists or have APIs: Melissa Data, Experian QAS, and SmartyStreets, to name a few.

(Due to getting flak for "advertising," I've truncated my answer at this point. It's up to you to find a solution that works for you.)

The Truth: Really, folks, I don't work at any of these companies. It's not an advertisement.

Call the pd.DataFrame constructor directly:

df = pd.DataFrame(table, columns=headers)
df

   Heading1  Heading2
0         1         2
1         3         4

The PrimeFaces ajax events sometimes are very poorly documented, so in most cases you must go to the source code and check yourself.

p:selectOneMenu supports change event:

<p:selectOneMenu ..>
    <p:ajax event="change" update="msgtext"
        listener="#{post.subjectSelectionChanged}" />
    <!--...-->
</p:selectOneMenu>

which triggers listener with AjaxBehaviorEvent as argument in signature:

public void subjectSelectionChanged(final AjaxBehaviorEvent event)  {...}

I got a similar error and it took me a while to realize that in my case I named the array variable payInvoices and the function also payInvoices. It confused AngularJs. Once I changed the name to processPayments() it finally worked. Just wanted to share this error and solution as it took me long time to figure this out.

You should also consider the OPTIMIZE FOR n ROWS clause. More details on all of this in the DB2 LUW documentation in the Guidelines for restricting SELECT statements topic:

• The OPTIMIZE FOR clause declares the intent to retrieve only a subset of the result or to give priority to retrieving only the first few rows. The optimizer can then choose access plans that minimize the response time for retrieving the first few rows.

You can with regular expressions Input Patterns (check browser compatibility)

<input id="password" name="password" type="password" pattern="^\S{6,}$" onchange="this.setCustomValidity(this.validity.patternMismatch ? 'Must have at least 6 characters' : ''); if(this.checkValidity()) form.password_two.pattern = this.value;" placeholder="Password" required>

<input id="password_two" name="password_two" type="password" pattern="^\S{6,}$" onchange="this.setCustomValidity(this.validity.patternMismatch ? 'Please enter the same Password as above' : '');" placeholder="Verify Password" required>

Adding my two cents for those searching for "Ensure that the org.eclipse.core.runtime bundle is resolved and started":

Adding "arbitrary" bundles to the list of bundles just because it seems that they are missing is not always the best solution. Sometimes it can get quite frustrating, because those new plugins might depend on other missing bundles, which need even more bundles and so on...

So, before adding a new dependency to the list of required bundles, make sure you understand why the bundle is needed (the debugger is your friend!).

This question here doesn't provide enough information to make this a valid answer in all cases, but if you encounter the message that the org.eclipse.core.runtime is missing, try setting the eclipse.application.launchDefault system property to false, especially if you try to run an application which is not an "eclipse application" (but maybe just a headless runtime on top of equinox).

This link might come in handy: http://help.eclipse.org/indigo/index.jsp?topic=%2Forg.eclipse.platform.doc.isv%2Freference%2Fmisc%2Fruntime-options.html, look for the eclipse.application.launchDefault system property.

rand(3..10)

When max is a Range, rand returns a random number where range.member?(number) == true.

add .ts file location in 'include' tag then compile work fine. ex.

In Java 8 that parameter is commonly used to print a warning message like this one:

Java HotSpot(TM) 64-Bit Server VM warning: ignoring option MaxPermSize=512m; support was removed in 8.0

The reason why you get this message in Java 8 is because Permgen has been replaced by Metaspace to address some of PermGen's drawbacks (as you were able to see for yourself, one of those drawbacks is that it had a fixed size).

FYI: an article on Metaspace: http://java-latte.blogspot.in/2014/03/metaspace-in-java-8.html

Observe if the view has the model required:

View

@model IEnumerable<WFAccess.Models.ViewModels.SiteViewModel>

<div class="row">
    <table class="table table-striped table-hover table-width-custom">
        <thead>
            <tr>
....

Controller

[HttpGet]
public ActionResult ListItems()
{
    SiteStore site = new SiteStore();
    site.GetSites();

    IEnumerable<SiteViewModel> sites =
        site.SitesList.Select(s => new SiteViewModel
        {
            Id = s.Id,
            Type = s.Type
        });

    return PartialView("_ListItems", sites);
}

In my case I Use a partial view but runs in normal views

You don't need to convert it. List<T> implements the IEnumerable<T> interface so it is already an enumerable.

This means that it is perfectly fine to have the following:

public IEnumerable<Book> GetBooks()
{
    List<Book> books = FetchEmFromSomewhere();    
    return books;
}

as well as:

public void ProcessBooks(IEnumerable<Book> books)
{
    // do something with those books
}

which could be invoked:

List<Book> books = FetchEmFromSomewhere();    
ProcessBooks(books);

Steven Levithan once wrote about how to implement a Faster JavaScript Trim. It’s definitely worth a look.

Another option is to create a shortcut with the following properties:

Target should be:

"%SYSTEMDRIVE%\Program Files (x86)\Git\bin\sh.exe" --login

Start in is the folder you wish your Git Bash prompt to launch into.

This is how I've added a bot to my channel and set up notifications:

1. Make sure the channel is public (you can set it private later)
2. Add administrators > Type the bot username and make it administrator
3. Your bot will join your channel
4. set a channel id by setting the channel url like

telegram.me/whateverIWantAndAvailable

the channel id will be @whateverIWantAndAvailable

Now set up your bot to send notifications by pusshing the messages here:

https://api.telegram.org/botTOKENOFTHEBOT/sendMessage?chat_id=@whateverIWantAndAvailable&text=Test

the message which bot will notify is: Test

I strongly suggest an urlencode of the message like

https://api.telegram.org/botTOKENOFTHEBOT/sendMessage?chat_id=@whateverIWantAndAvailable&text=Testing%20if%20this%20works

in php you can use urlencode("Test if this works"); in js you can encodeURIComponent("Test if this works");

I hope it helps

Seems like this question is kind of duplicate with another one, where I've collect some marshal/unmarshal solutions into one post. You may check it here: Dynamic tag names with JAXB.

In short:

1. A container class for @xmlAnyElement should be created
2. An XmlAdapter can be used in pair with @XmlJavaTypeAdapter to convert between the container class and Map<>;

Using boost is the best option as it helps you to provide a neat and concise code, but if you want to stick to STL

void listbox_add(const char* item, ListBox &lb)
{
    lb.add(item);
}

int foo()
{
    const char* starr[] = {"ram", "mohan", "sita"};
    ListBox listBox;
    std::for_each(starr,
                  starr + sizeof(starr)/sizeof(char*),
                  std::bind2nd(std::ptr_fun(&listbox_add), listBox));

}

There is an example of "Currying in ReasonML".

let run = () => {
    Js.log("Curryed function: ");
    let sum = (x, y) => x + y;
    Printf.printf("sum(2, 3) : %d\n", sum(2, 3));
    let per2 = sum(2);
    Printf.printf("per2(3) : %d\n", per2(3));
  };

Application.Exit is for Windows Forms applications - it informs all message pumps that they should terminate, waits for them to finish processing events and then terminates the application. Note that it doesn't necessarily force the application to exit.

Environment.Exit is applicable for all Windows applications, however it is mainly intended for use in console applications. It immediately terminates the process with the given exit code.

In general you should use Application.Exit in Windows Forms applications and Environment.Exit in console applications, (although I prefer to let the Main method / entry point run to completion rather than call Environment.Exit in console applications).

For more detail see the MSDN documentation.

Try this:

<img v-bind:src="'/media/avatars/' + joke.avatar" /> 

Don't forget single quote around your path string. also in your data check you have correctly defined image variable.

joke: {
  avatar: 'image.jpg'
}

You can use the CheckedChanged event for all your RadioButtons. Sender will be the unchecked and checked RadioButtons.

Many of the List implementation support limited support to add/remove, and Arrays.asList(membersArray) is one of that. You need to insert the record in java.util.ArrayList or use the below approach to convert into ArrayList.

With the minimal change in your code, you can do below to convert a list to ArrayList. The first solution is having a minimum change in your solution, but the second one is more optimized, I guess.

    String[] membersArray = request.getParameterValues('members');
    ArrayList<String> membersList = new ArrayList<>(Arrays.asList(membersArray));

OR

    String[] membersArray = request.getParameterValues('members');
    ArrayList<String> membersList = Stream.of(membersArray).collect(Collectors.toCollection(ArrayList::new));

I had to restart the browser after changing the ip address (laptop wireless DHCP) which was my "cross-host" I was referring to in my web app, which resolved the issue.

Also make sure all the cors headers being added by your browser/host are accepted/allowed by including then in the cors.allowed.headers

I've struggled with this before too.

Here's an analogy for what seems to be going on... A new visitor, Joe, comes to the site and logs in via the login page using FormsAuthentication. ASP.NET generates a new identity for Joe, and gives him a cookie. That cookie is like the key to the house, and as long as Joe returns with that key, he can open the lock. Each visitor is given a new key and a new lock to use.

When FormsAuthentication.SignOut() is called, the system tells Joe to lose the key. Normally, this works, since Joe no longer has the key, he cannot get in.

However, if Joe ever comes back, and does have that lost key, he is let back in!

From what I can tell, there is no way to tell ASP.NET to change the lock on the door!

The way I can live with this is to remember Joe's name in a Session variable. When he logs out, I abandon the Session so I don't have his name anymore. Later, to check if he is allowed in, I simply compare his Identity.Name to what the current session has, and if they don't match, he is not a valid visitor.

In short, for a web site, do NOT rely on User.Identity.IsAuthenticated without also checking your Session variables!

If it's a .mdf database and the connection string was saved when it was created, you should be able to access it via:

    Dim cn As SqlConnection = New SqlConnection(My.Settings.DatabaseNameConnectionString)

Hope that helps someone.

This query stands good for fetching the values between current date and its next 3 dates

SELECT * FROM tableName
WHERE columName BETWEEN CURDATE() AND DATE_ADD(CURDATE(), INTERVAL 3 DAY)

This will eventually add extra 3 days of buffer to the current date.

Answering to myself. From the RequireJS website:

//THIS WILL FAIL
define(['require'], function (require) {
    var namedModule = require('name');
});

This fails because requirejs needs to be sure to load and execute all dependencies before calling the factory function above. [...] So, either do not pass in the dependency array, or if using the dependency array, list all the dependencies in it.

My solution:

// Modules configuration (modules that will be used as Jade helpers)
define(function () {
    return {
        'moment':   'path/to/moment',
        'filesize': 'path/to/filesize',
        '_':        'path/to/lodash',
        '_s':       'path/to/underscore.string'
    };
});

The loader:

define(['jade', 'lodash', 'config'], function (Jade, _, Config) {
    var deps;

    // Dynamic require
    require(_.values(Config), function () {
        deps = _.object(_.keys(Config), arguments);

        // Use deps...
    });
});

Quite an old article on mssqlcity attempts to explain the types of locks:

Shared locks are used for operations that do not change or update data, such as a SELECT statement.

Update locks are used when SQL Server intends to modify a page, and later promotes the update page lock to an exclusive page lock before actually making the changes.

Exclusive locks are used for the data modification operations, such as UPDATE, INSERT, or DELETE.

What it doesn't discuss are Intent (which basically is a modifier for these lock types). Intent (Shared/Exclusive) locks are locks held at a higher level than the real lock. So, for instance, if your transaction has an X lock on a row, it will also have an IX lock at the table level (which stops other transactions from attempting to obtain an incompatible lock at a higher level on the table (e.g. a schema modification lock) until your transaction completes or rolls back).

The concept of "sharing" a lock is quite straightforward - multiple transactions can have a Shared lock for the same resource, whereas only a single transaction may have an Exclusive lock, and an Exclusive lock precludes any transaction from obtaining or holding a Shared lock.

Don't use jQuery to manipulate the DOM when you're using React. React components should render a representation of what they should look like given a certain state; what DOM that translates to is taken care of by React itself.

What you want to do is store the "state which determines what gets rendered" higher up the chain, and pass it down. If you are rendering n children, that state should be "owned" by whatever contains your component. eg:

class AppComponent extends React.Component {
  state = {
    numChildren: 0
  }

  render () {
    const children = [];

    for (var i = 0; i < this.state.numChildren; i += 1) {
      children.push(<ChildComponent key={i} number={i} />);
    };

    return (
      <ParentComponent addChild={this.onAddChild}>
        {children}
      </ParentComponent>
    );
  }

  onAddChild = () => {
    this.setState({
      numChildren: this.state.numChildren + 1
    });
  }
}

const ParentComponent = props => (
  <div className="card calculator">
    <p><a href="#" onClick={props.addChild}>Add Another Child Component</a></p>
    <div id="children-pane">
      {props.children}
    </div>
  </div>
);

const ChildComponent = props => <div>{"I am child " + props.number}</div>;

A single regular expression replace should do it:

var stringWithSmallIntegers = "4° 7' 34"W, 168° 1' 23"N";

var paddedString = stringWithSmallIntegers.replace(
    /\d+/g,
    function pad(digits) {
        return digits.length === 1 ? '0' + digits : digits;
    });

alert(paddedString);

shows the expected output.

If #error is not supported, you may use static_assert (C++0x) keyword. Or you may implement custom STATIC_ASSERT, or just declare an array of size 0, or have switch that has duplicate cases. In short, produce error at compile time and not at runtime

You need to use the proper git URL:

pip install git+https://github.com/jkbr/httpie.git#egg=httpie

Also see the VCS Support section of the pip documentation.

Don’t forget to include the egg=<projectname> part to explicitly name the project; this way pip can track metadata for it without having to have run the setup.py script.

also happens when you use jinja templates (which have different syntax for calling object methods) and you forget to set it in settings.py

Try:

set sw=2

set ts=2

set smartindent

I just figured out that for a case where the path involves the use of white space characters, for example, when I need to access the app xyz which location is :

C:\Program Files\ab cd\xyz.exe

To run this from windows cmd prompt, you need to use

C:\"Program Files"\"ab cd"\xyz.exe

or

"C:\Program Files\ab cd\xyz.exe"

The reason the code isn't working is because lastrow is measured from whatever sheet is currently active, and "A:A500" (or other number) is not a valid range reference.

Private Sub CommandButton1_Click()
    Dim lastrow As Long

    lastrow = Sheets("Summary Info").Range("A65536").End(xlUp).Row    ' or + 1
    Range("A3:E3").Copy Destination:=Sheets("Summary Info").Range("A" & lastrow)
End Sub

There are some great answers above. Here is an all-in-one solution. Three overloads for different circumstances.

// Extension method, call for any object, eg "if (x.IsNumeric())..."
public static bool IsNumeric(this object x) { return (x==null ? false : IsNumeric(x.GetType())); }

// Method where you know the type of the object
public static bool IsNumeric(Type type) { return IsNumeric(type, Type.GetTypeCode(type)); }

// Method where you know the type and the type code of the object
public static bool IsNumeric(Type type, TypeCode typeCode) { return (typeCode == TypeCode.Decimal || (type.IsPrimitive && typeCode != TypeCode.Object && typeCode != TypeCode.Boolean && typeCode != TypeCode.Char)); }

A filter argument with a trailing * can be evaluated almost instantaneously via an index lookup. A leading * implies a sequential search through the index, so it is O(N). It will take ages.

I suggest you reconsider the requirement.

Five years later (I hope this developer isn't still waiting for a fix to this..)

I had the same issue, caused by the same error: I was declaring the SmtpClient inside the loop.

The fix is simple - declare it once, outside the loop...

MailAddress mail = null;
SmtpClient client = new SmtpClient();
client.Port = 25;
client.EnableSsl = false;
client.DeliveryMethod = SmtpDeliveryMethod.Network;
client.UseDefaultCredentials = true;
client.Host = smtpAddress;       //  Enter your company's email server here!

for(int i = 0; i < number ; i++)
{
    mail = new MailMessage(iMail.from, iMail.to);
    mail.Subject = iMail.sub;
    mail.Body = iMail.body;
    mail.IsBodyHtml = true;
    mail.Priority = MailPriority.Normal;
    mail.Sender = from;
    client.Send(mail);
}
mail.Dispose();
client.Dispose();

I've tried many times.

And at last I just put autoindex on; in http but outside of server, and it's OK.

I wrote some code to do this, i'll put in a few snippets:

$dir = getcwd(); // Get current working directory where this .php script lives
$fileList = scandir($dir); // scan the directory where this .php lives and make array of file names

Then get the CSV headers so you can tell mysql how to import (note: make sure your mysql columns exactly match the csv columns):

//extract headers from .csv for use in import command
$headers = str_replace("\"", "`", array_shift(file($path)));
$headers = str_replace("\n", "", $headers);

Then send your query to the mysql server:

mysqli_query($cons, '
        LOAD DATA LOCAL INFILE "'.$path.'"
            INTO TABLE '.$dbTable.'  
            FIELDS TERMINATED by \',\' ENCLOSED BY \'"\'
            LINES TERMINATED BY \'\n\'
            IGNORE 1 LINES
            ('.$headers.')
            ;
        ')or die(mysql_error());

Improving upon the answer of @Arjen de Mooij a bit by making the AllowJsonGetAttribute applicable to mvc-controllers (not just individual action-methods):

using System.Web.Mvc;
public sealed class AllowJsonGetAttribute : ActionFilterAttribute, IActionFilter
{
    void IActionFilter.OnActionExecuted(ActionExecutedContext context)
    {
        var jsonResult = context.Result as JsonResult;
        if (jsonResult == null) return;

        jsonResult.JsonRequestBehavior = JsonRequestBehavior.AllowGet;
    }

    public override void OnResultExecuting(ResultExecutingContext filterContext)
    {
        var jsonResult = filterContext.Result as JsonResult;
        if (jsonResult == null) return;

        jsonResult.JsonRequestBehavior = JsonRequestBehavior.AllowGet;
        base.OnResultExecuting(filterContext);
    }
}

Your code only creates a time without a date. If your assumption is correct that when it runs the application.wait the time actually already reached that time it will wait for 24 hours exactly. I also worry a bit about calling now() multiple times (could be different?) I would change the code to

 application.wait DateAdd("s", 1, Now)

!important, after your CSS declaration.

div {
   color: blue !important; 

   /* This Is Now Working */
}

If you're working in a virtual environment (virtualenv), you'll definitely need to update the python.lintint.pylintPath setting (and probably the python.pythonPath setting, as well, if you haven't already) if you want linting to work, like this:

// File "settings.json" (workspace-specific one is probably best)
{
    // ...
    "python.linting.pylintPath": "C:/myproject/venv/Scripts/pylint.exe",
    "python.pythonPath": "C:/myproject/venv/Scripts/python.exe",
    // ...
}

That's for Windows, but other OSs are similar. The .exe extension was necessary for it to work for me on Windows, even though it's not required when actually running it in the console.

If you just want to disable it, then use the python.linting.pylintEnabled": false setting as mentioned in Ben Delaney's answer.

I spent a good deal of time researching this situation for my own needs. This and several other SO threads helped me a great deal, so I wanted to share what I came up with.

While having access to the interpolated query string is a significant benefit while troubleshooting, we wanted to be able to maintain a log of only certain queries (therefore, using the database logs for this purpose was not ideal). We also wanted to be able to use the logs to recreate the condition of the tables at any given time, therefore, we needed to make certain the interpolated strings were escaped properly. Finally, we wanted to extend this functionality to our entire code base having to re-write as little of it as possible (deadlines, marketing, and such; you know how it is).

My solution was to extend the functionality of the default PDOStatement object to cache the parameterized values (or references), and when the statement is executed, use the functionality of the PDO object to properly escape the parameters when they are injected back in to the query string. We could then tie in to execute method of the statement object and log the actual query that was executed at that time (or at least as faithful of a reproduction as possible).

As I said, we didn't want to modify the entire code base to add this functionality, so we overwrite the default bindParam() and bindValue() methods of the PDOStatement object, do our caching of the bound data, then call parent::bindParam() or parent::bindValue(). This allowed our existing code base to continue to function as normal.

Finally, when the execute() method is called, we perform our interpolation and provide the resultant string as a new property E_PDOStatement->fullQuery. This can be output to view the query or, for example, written to a log file.

The extension, along with installation and configuration instructions, are available on github:

https://github.com/noahheck/E_PDOStatement

DISCLAIMER:
Obviously, as I mentioned, I wrote this extension. Because it was developed with help from many threads here, I wanted to post my solution here in case anyone else comes across these threads, just as I did.

It's easy.. try this

html

<select id="ddl00">  
 <option>"test 01"</option>  
</select>

javascript

document.getElementById("ddl00").focus();

[^,]*$

might do. (Matches everything after the last comma).

Explanation: [^,] matches every character except for ,. The * denotes that the regexp matches any number of repetition of [^,]. The $ sign matches the end of the line.

As for me all things must be simple. For running script just need to execute

new ProcessBuilder("pathToYourShellScript").start();

Just adding my part to the above collection.

If you are after less code and maybe cool UI. Check out my GitHub for Progressbar for VBA

a customisable one:

The Dll is thought for MS-Access but should work in all VBA platform with minor changes. There is also an Excel file with samples. You are free to expand the vba wrappers to suit your needs.

This project is currently under development and not all errors are covered. So expect some!

You should be worried about 3rd party dlls and if you are, please feel free to use any trusted online antivirus before implementing the dll.

Peer dependency warnings, more often than not, can be ignored. The only time you will want to take action is if the peer dependency is missing entirely, or if the version of a peer dependency is higher than the version you have installed.

Let's take this warning as an example:

npm WARN @angular/[email protected] requires a peer of @angular/[email protected] but none is installed. You must install peer dependencies yourself.

With Angular, you would like the versions you are using to be consistent across all packages. If there are any incompatible versions, change the versions in your package.json, and run npm install so they are all synced up. I tend to keep my versions for Angular at the latest version, but you will need to make sure your versions are consistent for whatever version of Angular you require (which may not be the most recent).

In a situation like this:

npm WARN [email protected] requires a peer of @angular/core@^2.4.0 || ^4.0.0 but none is installed. You must install peer dependencies yourself.

If you are working with a version of Angular that is higher than 4.0.0, then you will likely have no issues. Nothing to do about this one then. If you are using an Angular version under 2.4.0, then you need to bring your version up. Update the package.json, and run npm install, or run npm install for the specific version you need. Like this:

npm install @angular/[email protected] --save

You can leave out the --save if you are running npm 5.0.0 or higher, that version saves the package in the dependencies section of the package.json automatically.

In this situation:

npm WARN optional SKIPPING OPTIONAL DEPENDENCY: [email protected] (node_modules\fsevents): npm WARN notsup SKIPPING OPTIONAL DEPENDENCY: Unsupported platform for [email protected]: wanted {"os":"darwin","arch":"any"} (current: {"os":"win32","arch":"x64"})

You are running Windows, and fsevent requires OSX. This warning can be ignored.

Hope this helps, and have fun learning Angular!

This is the answer for everyone who knows everything is correct and has checked 50 times.....

Make sure you are not repeatedly looking at RouteConfig.cs.

The file you want to edit is named WebApiConfig.cs

Also, it should probably look exactly like this:

using System.Web.Http;

namespace My.Epic.Website
{
    public static class WebApiConfig
    {
        public static void Register(HttpConfiguration config)
        {
          config.MapHttpAttributeRoutes();

          // api/Country/WithStates
          config.Routes.MapHttpRoute(
            name: "ControllerAndActionOnly",
            routeTemplate: "api/{controller}/{action}",
            defaults: new { },
            constraints: new { action = @"^[a-zA-Z]+([\s][a-zA-Z]+)*$" });

          config.Routes.MapHttpRoute(
            name: "DefaultActionApi",
            routeTemplate: "api/{controller}/{action}/{id}",
            defaults: new { id = RouteParameter.Optional }
          );
    }
    }
}

I could have saved myself about 3 hours.

Always use tax_query to get posts/products from a particular category or any other taxonomy. You can also get the products using ID/slug of particular taxonomy...

$the_query = new WP_Query( array(
    'post_type' => 'product',
    'tax_query' => array(
        array (
            'taxonomy' => 'product_cat',
            'field' => 'slug',
            'terms' => 'accessories',
        )
    ),
) );

while ( $the_query->have_posts() ) :
    $the_query->the_post();
    the_title(); echo "<br>";
endwhile;


wp_reset_postdata();

If you look at the code for the component you can see that it uses the className prop passed to it to combine with the row class to get the resulting set of classes (<Row className="aaa bbb"... works).Also, if you provide the id prop like <Row id="444" ... it will actually set the id attribute for the element.

Based on @Nick keets answer, here is a more complete example:

extension String: Error {} // Enables you to throw a string

extension String: LocalizedError { // Adds error.localizedDescription to Error instances
    public var errorDescription: String? { return self }
}

func test(color: NSColor) throws{
    if color == .red {
        throw "I don't like red"
    }else if color == .green {
        throw "I'm not into green"
    }else {
        throw "I like all other colors"
    }
}

do {
    try test(color: .green)
} catch let error where error.localizedDescription == "I don't like red"{
    Swift.print ("Error: \(error)") // "I don't like red"
}catch let error {
    Swift.print ("Other cases: Error: \(error.localizedDescription)") // I like all other colors
}

Originally published on my swift blog: http://eon.codes/blog/2017/09/01/throwing-simple-errors/

The solving is very simple

var my_obj = {1:[Array-Data], 2:[Array-Data]}
Object.keys(my_obj).map(function(property_name){ 
    return my_obj[property_name]; 
});

I think the MatTableDataSource object is some way linked with the data array that you pass to MatTableDataSource constructor.

For instance:

dataTable: string[];
tableDS: MatTableDataSource<string>;

ngOnInit(){
   // here your pass dataTable to the dataSource
   this.tableDS = new MatTableDataSource(this.dataTable); 
}

So, when you have to change data; change on the original list dataTable and then reflect the change on the table by call _updateChangeSubscription() method on tableDS.

For instance:

this.dataTable.push('testing');
this.tableDS._updateChangeSubscription();

That's work with me through Angular 6.

It's a measureable difference.

Run the following:

Create Table #TempTester (id int, col1 varchar(20), value varchar(20))
go

INSERT INTO #TempTester (id, col1, value)
VALUES
(1, 'this is #1', 'abcdefghij')
GO

INSERT INTO #TempTester (id, col1, value)
VALUES
(2, 'this is #2', 'foob'),
(3, 'this is #3', 'abdefghic'),
(4, 'this is #4', 'other'),
(5, 'this is #5', 'zyx'),
(6, 'this is #6', 'zyx'),
(7, 'this is #7', 'zyx'),
(8, 'this is #8', 'klm'),
(9, 'this is #9', 'klm'),
(10, 'this is #10', 'zyx')
GO 10000

CREATE CLUSTERED INDEX ixId ON #TempTester(id)CREATE CLUSTERED INDEX ixId ON #TempTester(id)

CREATE NONCLUSTERED INDEX ixTesting ON #TempTester(value)

Then:

SET SHOWPLAN_XML ON

Then:

SELECT * FROM #TempTester WHERE value LIKE 'abc%'

SELECT * FROM #TempTester WHERE value = 'abcdefghij'

The resulting execution plan shows you that the cost of the first operation, the LIKE comparison, is about 10 times more expensive than the = comparison.

If you can use an = comparison, please do so.

git fetch origin our-team

or

git pull origin our-team

but first you should make sure that you already on the branch you want to update to (featurex).

Replace

DataFrame object has powerful and flexible replace method:

DataFrame.replace(
        to_replace=None,
        value=None,
        inplace=False,
        limit=None,
        regex=False, 
        method='pad',
        axis=None)

Note, if you need to make changes in place, use inplace boolean argument for replace method:

Inplace

inplace: boolean, default False If True, in place. Note: this will modify any other views on this object (e.g. a column form a DataFrame). Returns the caller if this is True.

Snippet

df['BrandName'].replace(
    to_replace=['ABC', 'AB'],
    value='A',
    inplace=True
)

def valid = pointAddress.findAll { a ->
    validPointTypes.any { a.contains(it) }
}

Should do it

There are some other ways too. I have used the following script:

$File = "D:\Dev\somefilename.zip";
$ftp = "ftp://username:[email protected]/pub/incoming/somefilename.zip";

Write-Host -Object "ftp url: $ftp";

$webclient = New-Object -TypeName System.Net.WebClient;
$uri = New-Object -TypeName System.Uri -ArgumentList $ftp;

Write-Host -Object "Uploading $File...";

$webclient.UploadFile($uri, $File);

And you could run a script against the windows FTP command line utility using the following command

ftp -s:script.txt 

(Check out this article)

The following question on SO also answers this: How to script FTP upload and download?

Delete Dan from employee.data - No need to manage a new data.frame.

employee.data <- subset(employee.data, name!="Dan")

<p>Which one true?</p>
<select id="sel">
    <option>-</option>
    <option>A</option>
    <option>B</option>
    <option>C</option>
</select>

( display just first option of all options)

document.getElementById("sel").options.length=1; 

This is a bug in the Maven compiler plugin, related to JDK7 I think. Works fine with JDK6.

What about this?

function Delete_Directory($Dir) 
{
  if(is_dir($Dir))
  {
      $files = glob( $Dir . '*', GLOB_MARK ); //GLOB_MARK adds a slash to directories returned

      foreach( $files as $file )
      {
          Delete_Directory( $file );      
      }
      if(file_exists($Dir))
      {
          rmdir($Dir);
      }
  } 
  elseif(is_file($Dir)) 
  {
     unlink( $Dir );  
  }
}

Refrence: https://paulund.co.uk/php-delete-directory-and-files-in-directory

There is a another way also

1. step 1: create a sample.html file
2. step 2: create a div tag with some id=loadhtml Eg : <div id="loadhtml"></div>

3. step 3: in Any Controller

       var htmlcontent = $('#loadhtml ');
       htmlcontent.load('/Pages/Common/contact.html')
       $compile(htmlcontent.contents())($scope);
   

This Will Load a html page in Current page

This works for modifying childkey value using JSONObject. import used is

import org.json.JSONObject;

ex json:(convert json file to string while giving as input)

{
    "parentkey1": "name",
    "parentkey2": {
     "childkey": "test"
    },
}

Code

JSONObject jObject  = new JSONObject(String jsoninputfileasstring);
jObject.getJSONObject("parentkey2").put("childkey","data1");
System.out.println(jObject);

output:

{
    "parentkey1": "name",
    "parentkey2": {
     "childkey": "data1"
    },
}
