Even though the question is about gaining some space removing the address bar, you can also gain some space by toggling the bookmark bar on and off, using Ctrl + Shift + B, or ? Cmd + Shift + B, in Mac OS.

Since you are using enumerate hence your i is actually the index of the key rather than the key itself.

So, you are getting 3 in the first column of the row 3 4even though there is no key 3.

enumerate iterates through a data structure(be it list or a dictionary) while also providing the current iteration number.

Hence, the columns here are the iteration number followed by the key in dictionary enum

Others Solutions have already shown how to iterate over key and value pair so I won't repeat the same in mine.

Regards to your question... counting one Field? I decided to make it a question, but I hope it helps...

Say I have the following DataFrame

import numpy as np
import pandas as pd

df = pd.DataFrame(np.random.normal(0, 1, (5, 2)), columns=["A", "B"])

You could count a single column by

df.A.count()
#or
df['A'].count()

both evaluate to 5.

The cool thing (or one of many w.r.t. pandas) is that if you have NA values, count takes that into consideration.

So if I did

df['A'][1::2] = np.NAN
df.count()

The result would be

 A    3
 B    5

   const monthNames = ["January", "February", "March", "April", "May", "June",
        "July", "August", "September", "October", "November", "December"];
    const dateObj = new Date();
    const month = monthNames[dateObj.getMonth()];
    const day = String(dateObj.getDate()).padStart(2, '0');
    const year = dateObj.getFullYear();
    const output = month  + '\n'+ day  + ',' + year;

    document.querySelector('.date').textContent = output; 

This works:

    for i,r in data[::-1].iterrows():
        print(r['Odd'], r['Even'])

Can't upvote so I'll repost @jfs comment cause I think it should be more visible.

@AnneTheAgile: shell=True is not required. Moreover you should not use it unless it is necessary (see @ valid's comment). You should pass each command-line argument as a separate list item instead e.g., use ['command', 'arg 1', 'arg 2'] instead of "command 'arg 1' 'arg 2'". – jfs Mar 3 '15 at 10:02

Microsoft recently modified the reflection API rendering most of these answers obsolete. The following should work on modern platforms (including Xamarin.Forms and UWP):

obj.GetType().GetTypeInfo().GetDeclaredMethod("MethodName").Invoke(obj, yourArgsHere);

Or as an extension method:

public static object InvokeMethod<T>(this T obj, string methodName, params object[] args)
{
    var type = typeof(T);
    var method = type.GetTypeInfo().GetDeclaredMethod(methodName);
    return method.Invoke(obj, args);
}

Note:

• If the desired method is in a superclass of obj the T generic must be explicitly set to the type of the superclass.

• If the method is asynchronous you can use await (Task) obj.InvokeMethod(…).

Try these various things

df = pd.DataFrame({"A":["foo", "foo", "foo", "bar","foo"], "B":[0,1,1,1,1], "C":["A","A","B","A","A"]})

>>>df.drop_duplicates( "A" , keep='first')

or

>>>df.drop_duplicates( keep='first')

or

>>>df.drop_duplicates( keep='last')

By the way, if you need to add other characters such as "(" or ")" because the column may be used as "UPPER(bqr)", then those options can be added to the lists of before and after characters.

(\s|\(|\.|,|^)bqr(\s|,|\)|$)

You have to be cautious of double line breaks, which would cause double spaces. Use this really efficient regular expression:

$string = trim(preg_replace('/\s\s+/', ' ', $string));

Multiple spaces and newlines are replaced with a single space.

Edit: As others have pointed out, this solution has issues matching single newlines in between words. This is not present in the example, but one can easily see how that situation could occur. An alternative is to do the following:

$string = trim(preg_replace('/\s+/', ' ', $string));

In Java, you can escape quotes with \:

String value = " \"ROM\" ";

Does this work:

$msgid = $_GET['msgid'];

$oldMessage = '';

$deletedFormat = '';

//read the entire string
$str=file_get_contents('msghistory.txt');

//replace something in the file string - this is a VERY simple example
$str=str_replace($oldMessage, $deletedFormat,$str);

//write the entire string
file_put_contents('msghistory.txt', $str);

the query() method can do that very intuitively. Express your condition in a string to be evaluated like the following example :

df = df.query("columnNameA <= @x or columnNameB == @y")

with x and y are declared variables which you can refer to with @

You can write a script like this:

cd /X/Y
git pull

You can name it something like gitpull.
If you'd rather have it do arbitrary directories instead of /X/Y:

cd $1
git pull

Then you can call it with gitpull /X/Z
Lastly, you can try finding repositories. I have a ~/git folder which contains repositories, and you can use this to do a pull on all of them.

g=`find /X -name .git`
for repo in ${g[@]}
do
    cd ${repo}
    cd ..
    git pull
done

Just fyi, if you're trying to ensure the ship doesn't go off of the screen with

location-=1
if location==-1:
    location=0

you can probably better use

location -= 1
location = max(0, location)

This way if it skips -1 your program doesn't break

Personally, I couldn't use try/except KeyboardInterrupt because I was using standard socket (IPC) mode which is blocking. So the SIGINT was cueued, but came only after receiving data on the socket.

Setting a signal handler behaves the same.

On the other hand, this only works for an actual terminal. Other starting environments might not accept Ctrl+C, or pre-handle the signal.

Also, there are "Exceptions" and "BaseExceptions" in Python, which differ in the sense that interpreter needs to exit cleanly itself, so some exceptions have a higher priority than others (Exceptions is derived from BaseException)

The chosen answer is outdated, same goes to meltingice /ajax-chosen plugin.

With Select2 plugin got many bugs which is i can't resolve it.

Here my answer for this question.

I integrated my solution with function trigger after user type. Thanks to this answer : https://stackoverflow.com/a/5926782/4319179.

//setup before functions
  var typingTimer;                //timer identifier
  var doneTypingInterval = 2000;  //time in ms (2 seconds)
  var selectID = 'YourSelectId';    //Hold select id
  var selectData = [];           // data for unique id array

  //on keyup, start the countdown
  $('#' + selectID + '_chosen .chosen-choices input').keyup(function(){

      // Change No Result Match text to Searching.
      $('#' + selectID + '_chosen .no-results').html('Searching = "'+ $('#' + selectID + '_chosen .chosen-choices input').val() + '"');


      clearTimeout(typingTimer);  //Refresh Timer on keyup 
      if ($('#' + selectID + '_chosen .chosen-choices input').val()) {

           typingTimer = setTimeout(doneTyping, doneTypingInterval);  //Set timer back if got value on input

      }

  });

  //user is "finished typing," do something
  function doneTyping () {

            // This will prevent from select the same thing twice.
            if($.inArray(item.attr_hash,selectData) == -1){

              // if not match then append in select
              $('#' + selectID ).append('<option id="'+item.id+'" data-id = "'+item.id+'">' + item.data + '</option>');

            }            

          });

          // Update chosen again after append <option>
          $('#' + selectID ).trigger("chosen:updated");

        }
      });

  }

  // Chosen event listen on input change eg: after select data / deselect this function will be trigger
  $('#' + selectID ).on('change', function() {

I arrived at this peculiar, hard-to-debug error through a different route. My trouble ended up being that I was using a pattern rule in a build step when the target and the dependency were located in distinct directories. Something like this:

foo/apple.o: bar/apple.c $(FOODEPS)

%.o: %.c
    $(CC) $< -o $@

I had several dependencies set up this way, and was trying to use one pattern recipe for them all. Clearly, a single substitution for "%" isn't going to work here. I made explicit rules for each dependency, and I found myself back among the puppies and unicorns!

foo/apple.o: bar/apple.c $(FOODEPS)
    $(CC) $< -o $@

Hope this helps someone!

You need debounce!

Here is a jQuery plugin, and here is all you need to know about debounce. If you are coming here from Google and Underscore has found its way into the JSoup of your app, it has debounce baked right in!

For center or positioning the background image you should use background-position property . The background-position property sets the starting position of a background image from top and left sides of the element . The CSS Syntax is background-position : xvalue yvalue; .

"xvalue" and "yvalue" supported values are length units like px and percentage and direction names like left, right and etc .

The "xvalue" is the horizontal position of the background and starts from top of the element . It means if you use 50px it will be "50px" away from top of the elements . And "yvalue" is the vertical position that has the same condition .

So if you use background-position: center; your background image will be centered .

But I always use this code :

.yourclass {_x000D_
  background: url(image.png) no-repeat center /cover;_x000D_
 }

I know it is so confusing but it means :

.yourclass {_x000D_
  background-image: url(image.png);_x000D_
  background-position: center;_x000D_
  background-size: cover;_x000D_
  background-repeat: no-repeat;_x000D_
}

And I know that too the background-size is a new property and in the compressed code what is /cover but these codes means fill background sizing and positioning in windows desktop background .

You can see more details about background-position in here and background-size in here .

After reading all answers and some more research I get a few things.

Case statements are only 'labels'

In C, according to the specification,

§6.8.1 Labeled Statements:

labeled-statement:
    identifier : statement
    case constant-expression : statement
    default : statement

In C there isn't any clause that allows for a "labeled declaration". It's just not part of the language.

So

case 1: int x=10;
        printf(" x is %d",x);
break;

This will not compile, see http://codepad.org/YiyLQTYw. GCC is giving an error:

label can only be a part of statement and declaration is not a statement

Even

  case 1: int x;
          x=10;
            printf(" x is %d",x);
    break;

this is also not compiling, see http://codepad.org/BXnRD3bu. Here I am also getting the same error.

In C++, according to the specification,

labeled-declaration is allowed but labeled -initialization is not allowed.

See http://codepad.org/ZmQ0IyDG.

Solution to such condition is two

1. Either use new scope using {}

   case 1:
          {
              int x=10;
              printf(" x is %d", x);
          }
   break;
   

2. Or use dummy statement with label

   case 1: ;
              int x=10;
              printf(" x is %d",x);
   break;
   

3. Declare the variable before switch() and initialize it with different values in case statement if it fulfills your requirement

   main()
   {
       int x;   // Declare before
       switch(a)
       {
       case 1: x=10;
           break;
   
       case 2: x=20;
           break;
       }
   }
   

Some more things with switch statement

Never write any statements in the switch which are not part of any label, because they will never executed:

switch(a)
{
    printf("This will never print"); // This will never executed

    case 1:
        printf(" 1");
        break;

    default:
        break;
}

See http://codepad.org/PA1quYX3.

For a simple two- (or one) liner this code can be:

checkboxes = document.getElementsByName("NameOfCheckboxes");
selectedCboxes = Array.prototype.slice.call(checkboxes).filter(ch => ch.checked==true);

Here the Array.prototype.slice.call() part converts the object NodeList of all the checkboxes holding that name ("NameOfCheckboxes") into a new array, on which you then use the filter method. You can then also, for example, extract the values of the checkboxes by adding a .map(ch => ch.value) on the end of line 2. The => is javascript's arrow function notation.

I solved the problem by cat'ing all the pems together:

keytool -import -trustcacerts -alias root -file chain.pem -keystore MyDSKeyStore.jks -storepass MYPASSWORD

(keytool didn't know what to do with a PKCS7 formatted key)

You can read database value in to a variable and then set the variable as follows

$app_container->assign('checked_flag', $db_data=='0'  ? '' : 'checked');

And in html you can just use the checked_flag variable as follows

<input type="checkbox" id="chk_test" name="chk_test" value="1" {checked_flag}>

my_data is a struct with name as a field and data[] is arry of structs, you are initializing each index. read following:

5.20 Designated Initializers:

In a structure initializer, specify the name of a field to initialize with .fieldname =' before the element value. For example, given the following structure,

struct point { int x, y; };

the following initialization

struct point p = { .y = yvalue, .x = xvalue };

is equivalent to

struct point p = { xvalue, yvalue };

Another syntax which has the same meaning, obsolete since GCC 2.5, is fieldname:', as shown here:

struct point p = { y: yvalue, x: xvalue };

You can also write:

my_data data[] = {
    { .name = "Peter" },
    { .name = "James" },
    { .name = "John" },
    { .name = "Mike" }
};

as:

my_data data[] = {
    [0] = { .name = "Peter" },
    [1] = { .name = "James" },
    [2] = { .name = "John" },
    [3] = { .name = "Mike" }
}; 

or:

my_data data[] = {
    [0].name = "Peter",
    [1].name = "James",
    [2].name = "John",
    [3].name = "Mike"
}; 

Second and third forms may be convenient as you don't need to write in order for example all of the above example are equivalent to:

my_data data[] = {
    [3].name = "Mike",
    [1].name = "James",
    [0].name = "Peter",
    [2].name = "John"
}; 

If you have multiple fields in your struct (for example, an int age), you can initialize all of them at once using the following:

my_data data[] = {
    [3].name = "Mike",
    [2].age = 40,
    [1].name = "James",
    [3].age = 23,
    [0].name = "Peter",
    [2].name = "John"
}; 

To understand array initialization read Strange initializer expression?

I found deleting the app from the device and re-installing with Xcode solved this issue.

You can use Server.Map path to give relative path and then you can either create image using base64 conversion or you can just add base64 string to image src.

byte[] imageArray = System.IO.File.ReadAllBytes(Server.MapPath("~/Images/Upload_Image.png"));

string base64ImageRepresentation = Convert.ToBase64String(imageArray);

You can write as you show in example, but than you get build-error.

For fix this:

1. print app.url_map () in you root .py
2. you see something like:

<Rule '/<userId>/<username>' (HEAD, POST, OPTIONS, GET) -> user.show_0>

and

<Rule '/<userId>' (HEAD, POST, OPTIONS, GET) -> .show_1>

3. than in template you can {{ url_for('.show_0', args) }} and {{ url_for('.show_1', args) }}

In phpMyAdmin, navigate to the table in question and click the "Operations" tab. On the left under Table Options you will be allowed to set the current AUTO_INCREMENT value.

If you are in an environment of ECMAScript 6, using the Spread Operator you could do it this way:

var arr1 = ['a','b','c'];_x000D_
var arr2 = [...arr1]; //copy arr1_x000D_
arr2.push('d');_x000D_
_x000D_
console.log(arr1)_x000D_
console.log(arr2)

From a software tester's perspective

#pragma once is shorter than an include guard, less error prone, supported by most compilers, and some say that it compiles faster (which is not true [any longer]).

But I still suggest you go with standard #ifndef include guards.

Why #ifndef?

Consider a contrived class hierarchy like this where each of the classes A, B, and C lives inside its own file:

a.h

#ifndef A_H
#define A_H

class A {
public:
  // some virtual functions
};

#endif

b.h

#ifndef B_H
#define B_H

#include "a.h"

class B : public A {
public:
  // some functions
};

#endif

c.h

#ifndef C_H
#define C_H

#include "b.h"

class C : public B {
public:
  // some functions
};

#endif

Now let's assume you are writing tests for your classes and you need to simulate the behaviour of the really complex class B. One way to do this would be to write a mock class using for example google mock and put it inside a directory mocks/b.h. Note, that the class name hasn't changed but it's only stored inside a different directory. But what's most important is that the include guard is named exactly the same as in the original file b.h.

mocks/b.h

#ifndef B_H
#define B_H

#include "a.h"
#include "gmock/gmock.h"

class B : public A {
public:
  // some mocks functions
  MOCK_METHOD0(SomeMethod, void());
};

#endif

What's the benefit?

With this approach you can mock the behaviour of class B without touching the original class or telling C about it. All you have to do is put the directory mocks/ in the include path of your complier.

Why can't this be done with #pragma once?

If you would have used #pragma once, you would get a name clash because it cannot protect you from defining the class B twice, once the original one and once the mocked version.

<div class="row-2">
 <ul>
     <li><a href="index.html" class="active"><p style="margin-top: 10px;">Buy</p></a></li>
 </ul>

Play with it

Just do:

echo substr($string, 0, -3);

You don't need to use a strlen call, since, as noted in the substr docs:

If length is given and is negative, then that many characters will be omitted from the end of string

DECLARE @IDQuery VARCHAR(MAX)
SET @IDQuery = 'SELECT ID FROM SomeTable WHERE Condition=Something'
DECLARE @ExcludedList TABLE(ID VARCHAR(MAX))
INSERT INTO @ExcludedList EXEC(@IDQuery)    
SELECT * FROM A WHERE Id NOT IN (@ExcludedList)

I know I'm responding to an old post but I wanted to share an example of how to use Variable Tables when one wants to avoid using dynamic SQL. I'm not sure if its the most efficient way, however this has worked in the past for me when dynamic SQL was not an option.

Better to just use .addClass() and .removeClass() even if you have 1 or more styles to change. It's more maintainable and readable.

If you really have the urge to do multiple CSS properties, then use the following:

.css({
   'font-size' : '10px',
   'width' : '30px',
   'height' : '10px'
});

NB!
Any CSS properties with a hyphen need to be quoted.
I've placed the quotes so no one will need to clarify that, and the code will be 100% functional.

Working gradle dependency

Try this:

compile 'org.jbundle.util.osgi.wrapped:org.jbundle.util.osgi.wrapped.org.apache.http.client:4.1.2'

This is not direct answer to the original question but I hope this suggestion helps someones with similar error:

When using a newer web-api with Webpack+Babel for transpiling and you get

Module parse failed: 'import' and 'export' may only appear at the top level

then you probably forgot to import a polyfill.

For example:
when using fetch() api and targeting for es2015, you should

1. add whatwg-fetch polyfill to package.json
2. add import {fetch} from 'whatwg-fetch'

In C++, your source files are usually parsed from top to bottom in a single pass, so any variable or function must be declared before they can be used. There are some exceptions to this, like when defining functions inline in a class definition, but that's not the case for your code.

Either move the definition of integrate above the one for getSkewNormal, or add a forward declaration above getSkewNormal:

double integrate (double start, double stop, int numSteps, Evaluatable evalObj);

The same applies for sum.

I was unable to use this answer because my linter won't allow unchecked casts.

Here is an alternative you can use. I feel it is actually a cleaner solution.

public <T> List<T> parseJsonArray(String json, Class<T> clazz) throws JsonProcessingException {
  var tree = objectMapper.readTree(json);
  var list = new ArrayList<T>();
  for (JsonNode jsonNode : tree) {
    list.add(objectMapper.treeToValue(jsonNode, clazz));
  }
  return list;

adb shell am broadcast -a android.intent.action.MASTER_CLEAR

or as root

adb shell  "su -c 'am broadcast -a android.intent.action.MASTER_CLEAR'"

If anyone facing similar type of error while adding ShimmerRecyclerView Loader in android , make sure to add maven { url "https://jitpack.io" } under allprojects like below.

    allprojects {
    repositories {
        google()
        jcenter()
        //add it here
        maven { url "https://jitpack.io" }
      }
   }

I had a requirement to provide a report showing details by month where the date field was formatted as date & time, I simply changed the formatting of the date column to "General" and then used the following formula in a new column,

=CONCATENATE(YEAR(C2),MONTH(C2)) 

<script type="text/javascript">

function uwtPBSTree_NodeChecked(treeId, nodeId, bChecked) 
{
    //debugger;
    var selectedNode = igtree_getNodeById(nodeId);
    var ParentNodes = selectedNode.getChildNodes();

    var length = ParentNodes.length;

    if (bChecked) 
    {
/*                if (length != 0) {
                    for (i = 0; i < length; i++) {
                        ParentNodes[i].setChecked(true);
                    }
    }*/
    }
    else 
    {
        if (length != 0) 
        {
            for (i = 0; i < length; i++) 
            {
                ParentNodes[i].setChecked(false);
            }
        }

in my case: 1. in IIS Manager, in left tree, left click the computer name, in right dialog click ISAPI and CGT limitation, in open dialog, select ASP.NET v4.0.30319 and select enable. There is two ASP.Net v4.0, one for 32bit, another for 64 bit. select depending on your OS bit. 2. in left tree select app pool, in right dialog, select the app pool your website used. double click that pool, in open dialog, .net framke item select .net framework v.4.0.30319. and pipe..item select integate. Maybe there is some wrong translation above because my OS is not English version.

Use the Insert method:

ti.Insert(0, initialItem);

The R file can't be generated if your layout contains errors. If your res folder is empty, then it's safe to assume that there's no res/layout folder with any layouts in it, but your activity is probably calling setContentView and not finding anything -- that qualifies as a problem with your layout.

This comes down to browser image support; it looks like the only mainstream browser that supports tiff is Safari:

http://en.wikipedia.org/wiki/Comparison_of_web_browsers#Image_format_support

Where are you getting the tiff images from? Is it possible for them to be generated in a different format?

If you have a static set of images then I'd recommend using something like PaintShop Pro to batch convert them, changing the format.

If this isn't an option then there might be some mileage in looking for a pre-written Java applet (or another browser plugin) that can display the images in the browser.

I really don't understand why Javascript world trying to do thing more complicated. Why not just download and include in html? Trying to have something like Maven in Java? But we have to manually include it in html anyway? So, what is the point? Maybe someday I will understand but not now.

This is how I can get it

• download & install NodeJs
• run "npm install popper.js --save"

• then I get this message

  [email protected] added 1 package in 1.215s

• then where is "add package" ? very informative , right? I found it in my C:\Users\surasin\node_modules\popper.js\dist

Hope this help

I created a string extension for this, hope it helps.

public static string GetStringAfterChar(this string value, char substring)
    {
        if (!string.IsNullOrWhiteSpace(value))
        {
            var index = value.LastIndexOf(substring);
            return index > 0 ? value.Substring(index + 1) : value;
        }

        return string.Empty;
    }

I know it's a relative old post but, I would like to share what worked for me: I've simply input "http://" before "localhost" in the url. Hope it helps somebody.

You should use @input:

<input @input="handleInput" />

@input fires when user changes input value.

@change fires when user changed value and unfocus input (for example clicked somewhere outside)

You can see the difference here: https://jsfiddle.net/posva/oqe9e8pb/

Win: CTRL+P or CTRL+E

Mac: CMD+P or CMD+E

Don't want to remember another shortcut?

Open the Command Palette:

• Menu: View -> Command Palette
• Windows Shortcut: Ctrl+Shift+P

and hit backspace to delete ">" character and then begin typing to search for files via filename. :)

SQL is expecting the GUID as a string. The following in C# returns a string Sql is expecting.

"'" + Guid.NewGuid().ToString() + "'"

Something like

INSERT INTO TABLE (GuidID) VALUE ('4b5e95a7-745a-462f-ae53-709a8583700a')

is what it should look like in SQL.

I developed a software tool that opens (most) Pickle files directly in your browser (nothing is transferred so it's 100% private):

https://pickleviewer.com/

Hiya demo http://jsfiddle.net/LYTbc/

this is a reference to the DOM element, so you can wrap it directly.

attr api: http://api.jquery.com/attr/

The .attr() method gets the attribute value for only the first element in the matched set.

have a nice one, cheers!

code

$(document).ready(function () {
    $(".inputs").click(function () {
         alert(this.id);

        alert(" or " + $(this).attr("id"));

    });

});?

The beauty of the React Native is that it supports lots of JS libraries like Moment.js. Using moment.js would be a better/easier way to handle date/time instead coding from scratch

just run this in the terminal (yarn add moment also works if using React's built-in package manager):

npm install moment --save

And in your React Native js page:

import Moment from 'moment';

render(){
    Moment.locale('en');
    var dt = '2016-05-02T00:00:00';
    return(<View> {Moment(dt).format('d MMM')} </View>) //basically you can do all sorts of the formatting and others
}

You may check the moment.js official docs here https://momentjs.com/docs/

This exception comes from the client, right? Please perform a forward and reverse DNS lookup of the server hostname. Your server has incorrect DNS entries. They are absolutely crucial for Kerberos. The proper place is your DNS server, in your case: domain controller. Figure out the IP address of your DNS server and contact your admin. The other option is a missing SPN, please check that too.

you can try setting the padding instead of the height/width.

i had the same issue. go to Sql Server Configuration management->SQL Server network config->protocols for 'servername' and check named pipes is enabled.

Warning you get is done by compiler, not by library (or utility method).

Simplest way using Jackson directly would be:

HashMap<String,Object> props;

// src is a File, InputStream, String or such
props = new ObjectMapper().readValue(src, new TypeReference<HashMap<String,Object>>() {});
// or:
props = (HashMap<String,Object>) new ObjectMapper().readValue(src, HashMap.class);
// or even just:
@SuppressWarnings("unchecked") // suppresses typed/untype mismatch warnings, which is harmless
props = new ObjectMapper().readValue(src, HashMap.class);

Utility method you call probably just does something similar to this.

Many of these answers were too slow for my source files. My source files were SQL files between 10 MB and 800 MB that needed to split into files of roughly equal line counts.

I found some of the previous answers which use Add-Content to be quite slow. Waiting many hours for a split to finish wasn't uncommon.

I didn't try Typhlosaurus's answer, but it looks to only do splits by file size, not line count.

The following has suited my purposes.

$sw = new-object System.Diagnostics.Stopwatch
$sw.Start()
Write-Host "Reading source file..."
$lines = [System.IO.File]::ReadAllLines("C:\Temp\SplitTest\source.sql")
$totalLines = $lines.Length

Write-Host "Total Lines :" $totalLines

$skip = 0
$count = 100000; # Number of lines per file

# File counter, with sort friendly name
$fileNumber = 1
$fileNumberString = $filenumber.ToString("000")

while ($skip -le $totalLines) {
    $upper = $skip + $count - 1
    if ($upper -gt ($lines.Length - 1)) {
        $upper = $lines.Length - 1
    }

    # Write the lines
    [System.IO.File]::WriteAllLines("C:\Temp\SplitTest\result$fileNumberString.txt",$lines[($skip..$upper)])

    # Increment counters
    $skip += $count
    $fileNumber++
    $fileNumberString = $filenumber.ToString("000")
}

$sw.Stop()

Write-Host "Split complete in " $sw.Elapsed.TotalSeconds "seconds"

For a 54 MB file, I get the output...

Reading source file...
Total Lines : 910030
Split complete in  1.7056578 seconds

I hope others looking for a simple, line-based splitting script that matches my requirements will find this useful.

Pscp.exe is painfully slow.

Uploading files using WinSCP is like 10 times faster.

So, to do that from command line, first you got to add the winscp.com file to your %PATH%. It's not a top-level domain, but an executable .com file, which is located in your WinSCP installation directory.

Then just issue a simple command and your file will be uploaded much faster putty ever could:

WinSCP.com /command "open sftp://username:[email protected]:22" "put your_large_file.zip /var/www/somedirectory/" "exit"

And make sure your check the synchronize folders feature, which is basically what rsync does, so you won't ever want to use pscp.exe again.

WinSCP.com /command "help synchronize"

The compiler may add padding for alignment requirements. Note that this applies not only to padding between the fields of a struct, but also may apply to the end of the struct (so that arrays of the structure type will have each element properly aligned).

For example:

struct foo_t {
    int x;
    char c;
};

Even though the c field doesn't need padding, the struct will generally have a sizeof(struct foo_t) == 8 (on a 32-bit system - rather a system with a 32-bit int type) because there will need to be 3 bytes of padding after the c field.

Note that the padding might not be required by the system (like x86 or Cortex M3) but compilers might still add it for performance reasons.

I would use VMs. Create an XP (or whatever) VM using VMware Workstation or similar product, and snapshot it. That is your oldest version. Then perform the upgrades one at a time, and snapshot each time. Then you can switch to any snapshot you need later, or clone independent VMs based on all the snapshots so you can run them all at once. You probably want to test on different operating systems as well as different versions, so VMs generalize that solution as well rather than some one-off solution of hacking multiple IEs to coexist on a single instance of Windows.

Another way to do it:

declare @week_number int = 6280 -- 2020-05-07
declare @start_weekday int = 0 -- Monday
declare @end_weekday int = 6 -- next Sunday

select 
    dateadd(week, @week_number, @start_weekday), 
    dateadd(week, @week_number, @end_weekday)

Explanation:

• @week_number is the week number since the initial calendar date '1900-01-01'. It can be computed this way: select datediff(week, 0, @wedding_date) as week_number
• @start_weekday for the week first day: 0 for Monday, -1 if Sunday
• @end_weekday for the week last day: 6 for next Sunday, 5 if Saturday
• dateadd(week, @week_number, @end_weekday): adds the given number of weeks and the given number of days into the initial calendar date '1900-01-01'

Use object.defineProperty

With this, you can easily access cookies

Object.defineProperty(window, "Cookies", {
    get: function() {
        return document.cookie.split(';').reduce(function(cookies, cookie) {
            cookies[cookie.split("=")[0]] = unescape(cookie.split("=")[1]);
            return cookies
        }, {});
    }
});

From now on you can just do:

alert( Cookies.obligations );

This will automatically update too, so if you change a cookie, the Cookies will change too.

Assuming you want to add this path for all users on the system, add the following line to your /etc/profile.d/play.sh (and possibly play.csh, etc):

PATH=$PATH:/home/me/play
export PATH

This is the case because the pointer you have for the submodule isn’t what is actually in the submodule directory. To fix this, you must run git submodule update again:

There isn't one built in but you could write your own quite easily:

(function($) {
    $.fn.invisible = function() {
        return this.each(function() {
            $(this).css("visibility", "hidden");
        });
    };
    $.fn.visible = function() {
        return this.each(function() {
            $(this).css("visibility", "visible");
        });
    };
}(jQuery));

You can then call this like so:

$("#someElem").invisible();
$("#someOther").visible();

Here's a working example.

SELECT
  AGE('2012-03-05', '2010-04-01'),
  DATE_PART('year', AGE('2012-03-05', '2010-04-01')) AS years,
  DATE_PART('month', AGE('2012-03-05', '2010-04-01')) AS months,
  DATE_PART('day', AGE('2012-03-05', '2010-04-01')) AS days;

This will give you full years, month, days ... between two dates:

          age          | years | months | days
-----------------------+-------+--------+------
 1 year 11 mons 4 days |     1 |     11 |    4

More detailed datediff information.

Just like @Dampes8N said:

$result = mysql_query($sql,$conecction);
$fp = fopen('file.csv', 'w');
while($row = mysql_fetch_assoc($result)){
    fputcsv($fp, $row);
}

Hope this helps.

ElcomSoft makes Advanced Office Password Breaker and Advanced Office Password Recovery products which may apply to this case, as long as the document was created in Office 2007 or prior.

Mine is more simple than the others hopefully you can understand this if you are a some what new programmer like myself.

import java.util.Scanner;
import java.lang.Math;

public class DigitsSum {

    public static void main(String[] args) {

        Scanner in = new Scanner(System.in);
        int digit = 0;
        System.out.print("Please enter a positive integer: ");
        digit = in.nextInt();
        int D1 = 0;
        int D2 = 0;
        int D3 = 0;
        int G2 = 0;
        D1 = digit / 100;
        D2 = digit % 100;
        G2 = D2 / 10;
        D3 = digit % 10;


        System.out.println(D3 + G2 + D1);

    }
}

Yet another alternative: 

Select FORMAT(date,'MM.yy')
...
...
group by FORMAT(date,'MM.yy')

template <class ForwardIterator>
ForwardIterator min_element ( ForwardIterator first, ForwardIterator last )
{
    ForwardIterator lowest = first;
    if (first == last) return last;
    while (++first != last)
    if (*first < *lowest) 
        lowest = first;
    return lowest;
}

1. Use an event handler to notify other the form to handle it.
2. Create a public property on the child form and access it from parent form (with a valid cast).
3. Create another constructor on the child form for setting form's initialization parameters
4. Create custom events and/or use (static) classes.

The best practice would be #4 if you are using non-modal forms.

Start the project with Ctrl+F5 instead of just F5.

The console window will now stay open with the Press any key to continue . . . message after the program exits.

Note that this requires the Console (/SUBSYSTEM:CONSOLE) linker option, which you can enable as follows:

1. Open up your project, and go to the Solution Explorer. If you're following along with me in K&R, your "Solution" will be 'hello' with 1 project under it, also 'hello' in bold.
2. Right click on the 'hello" (or whatever your project name is.)
3. Choose "Properties" from the context menu.
4. Choose Configuration Properties>Linker>System.
5. For the "Subsystem" property in the right-hand pane, click the drop-down box in the right hand column.
6. Choose "Console (/SUBSYSTEM:CONSOLE)"
7. Click Apply, wait for it to finish doing whatever it does, then click OK. (If "Apply" is grayed out, choose some other subsystem option, click Apply, then go back and apply the console option. My experience is that OK by itself won't work.)

CTRL-F5 and the subsystem hints work together; they are not separate options.

Have a look at using DATEADD

something like

SELECT DATEADD(minute, -30, GETDATE())

From Docker documentation:

docker export does not export the contents of volumes associated with the container. If a volume is mounted on top of an existing directory in the container, docker export will export the contents of the underlying directory, not the contents of the volume. Refer to Backup, restore, or migrate data volumes in the user guide for examples on exporting data in a volume.

You have to specify the format (fmt) of you data in savetxt, in this case as a string (%s):

num.savetxt('test.txt', DAT, delimiter=" ", fmt="%s") 

The default format is a float, that is the reason it was expecting a float instead of a string and explains the error message.

dynamic_cast can determine if the type contains the target type anywhere in the inheritance hierarchy (yes, it's a little-known feature that if B inherits from A and C, it can turn an A* directly into a C*). typeid() can determine the exact type of the object. However, these should both be used extremely sparingly. As has been mentioned already, you should always be avoiding dynamic type identification, because it indicates a design flaw. (also, if you know the object is for sure of the target type, you can do a downcast with a static_cast. Boost offers a polymorphic_downcast that will do a downcast with dynamic_cast and assert in debug mode, and in release mode it will just use a static_cast).

Just to expand on the answer(s) above, in my case, I required sending a yes/no against a single ID serialized to my backend catch.

I set the checkbox elements to contain the ID of a particular database column, aka (default checked):

(Laravel Blade)

<div class="checkbox">
    <label>
        <input type="checkbox" value="{{ $heading->id }}" checked> {{ $heading->name }}
    </label>
</div>

When I did my submission, I grabbed the data with:

(jQuery)

let form = $('#formID input[type="checkbox"]').map(function() {
                return { id: this.value, value: this.checked ? 1 : 0 };
           }).get();

var data = JSON.stringify(form);
$.post( "/your/endpoint", data );

Mostly you don't see a difference, unless you are using set -u:

/home/user1> var=""
/home/user1> echo $var

/home/user1> set -u
/home/user1> echo $var

/home/user1> unset var
/home/user1> echo $var
-bash: var: unbound variable

So really, it depends on how you are going to test the variable.

I will add that my preferred way of testing if it is set is:

[[ -n $var ]]  # True if the length of $var is non-zero

or

[[ -z $var ]]  # True if zero length

Jérôme Petazzoni has a pretty interesting blog post on how to Attach a volume to a container while it is running. This isn't something that's built into Docker out of the box, but possible to accomplish.

As he also points out

This will not work on filesystems which are not based on block devices.

It will only work if /proc/mounts correctly lists the block device node (which, as we saw above, is not necessarily true).

Also, I only tested this on my local environment; I didn’t even try on a cloud instance or anything like that

YMMV

std::string num = "0.6";
double temp = ::atof(num.c_str());

Does it for me, it is a valid C++ syntax to convert a string to a double.

You can do it with the stringstream or boost::lexical_cast but those come with a performance penalty.

Ahaha you have a Qt project ...

QString winOpacity("0.6");
double temp = winOpacity.toDouble();

Extra note:
If the input data is a const char*, QByteArray::toDouble will be faster.

1. You can set it as background-image and use text-indent or a padding to shift the text to the right.
2. You can break it up into two elements.

Honestly, I would avoid usage of HTML5/CSS3 without a good fallback. There are just too many people using old browsers that don't support all the new fancy stuff. It will take a while before we can drop the fallback, unfortunately :(

The first method I mentioned is the safest and easiest. Both ways requires Javascript to hide the icon.

CSS:

input#search {
    background-image: url(bg.jpg);
    background-repeat: no-repeat;
    text-indent: 20px;
}

HTML:

<input type="text" id="search" name="search" onchange="hideIcon(this);" value="search" />

Javascript:

function hideIcon(self) {
    self.style.backgroundImage = 'none';
}

September 25h, 2013

I can't believe I said "Both ways requires JavaScript to hide the icon.", because this is not entirely true.

The most common timing to hide placeholder text is on change, as suggested in this answer. For icons however it's okay to hide them on focus which can be done in CSS with the active pseudo-class.

#search:active { background-image: none; }

Heck, using CSS3 you can make it fade away!

Of course, there's the CSS3 ::before pseudo-elements too. Beware of browser support though!

            Chrome  Firefox     IE      Opera   Safari
:before     (yes)   1.0         8.0     4       4.0
::before    (yes)   1.5         9.0     7       4.0

Use the built-in VBA function Val, if the numbers are at the front end of the string:

Dim str as String
Dim lng as Long

str = "1 149 xyz"
lng = Val(str)

lng = 1149

Val Function, on MSDN

Another solution that does not involve converting to/from strings:

from math import log10

def decompose(n):
    if n == 0:
        return [0]
    b = int(log10(n)) + 1
    return [(n // (10 ** i)) % 10 for i in reversed(range(b))]

i used pixi.js and pixi-sound.js to achieve the auto play in chrome and firefox.

<script>

            PIXI.sound.Sound.from({
            url: 'audios/tuto.mp3',
            loop:true,
            preload: true,
            loaded: function(err, sound) {
                    sound.play();

            document.querySelector("#paused").addEventListener('click', function() {
            const paused = PIXI.sound.togglePauseAll();

            this.className = this.className.replace(/\b(on|off)/g, '');
            this.className += paused ? 'on' : 'off';

            });
            }
            });

</script>

HTML:

<button class="btn1 btn-lg off" id="paused">
    <span class="glyphicon glyphicon-pause off"></span>
    <span class="glyphicon glyphicon-play on"></span>
</button>

it also works on mobile devices but user have to touch somewhere on the screen to trigger the sound.

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

Screen is a full-screen window manager that multiplexes a physical terminal between several processes, typically interactive shells. There is a scrollback history buffer for each virtual terminal and a copy-and-paste mechanism that allows the user to move text regions between windows.

"SET serveroutput ON" is a SQL*Plus command and is not valid PL/SQL.

Based on @lijat, here is a simplified implementation. In my spring-based application I simply load this as a bean.

public static void configureLog4jFromSystemProperties()
{
  final String LOGGER_PREFIX = "log4j.logger.";

  for(String propertyName : System.getProperties().stringPropertyNames())
  {
    if (propertyName.startsWith(LOGGER_PREFIX)) {
      String loggerName = propertyName.substring(LOGGER_PREFIX.length());
      String levelName = System.getProperty(propertyName, "");
      Level level = Level.toLevel(levelName); // defaults to DEBUG
      if (!"".equals(levelName) && !levelName.toUpperCase().equals(level.toString())) {
        logger.error("Skipping unrecognized log4j log level " + levelName + ": -D" + propertyName + "=" + levelName);
        continue;
      }
      logger.info("Setting " + loggerName + " => " + level.toString());
      Logger.getLogger(loggerName).setLevel(level);
    }
  }
}

ASP.Net Web API has Authorization Server build-in already. You can see it inside Startup.cs when you create a new ASP.Net Web Application with Web API template.

OAuthOptions = new OAuthAuthorizationServerOptions
{
    TokenEndpointPath = new PathString("/Token"),
    Provider = new ApplicationOAuthProvider(PublicClientId),
    AuthorizeEndpointPath = new PathString("/api/Account/ExternalLogin"),
    AccessTokenExpireTimeSpan = TimeSpan.FromDays(14),
    // In production mode set AllowInsecureHttp = false
    AllowInsecureHttp = true
};

All you have to do is to post URL encoded username and password inside query string.

/Token/userName=johndoe%40example.com&password=1234&grant_type=password

If you want to know more detail, you can watch User Registration and Login - Angular Front to Back with Web API by Deborah Kurata.

data 52e - Returns when username is valid but password/credential is invalid.

You probably need something like

String dn = "cn=" + userName + "," + "CN=Users," + base;  

I personally prefer the simpler syntax of the ~ operator.

SELECT id FROM TAG_TABLE WHERE 'aaaaaaaa' ~ tag_name;

Worth reading through Difference between LIKE and ~ in Postgres to understand the difference. `

CONVERT is SQL Server specific, CAST is ANSI.

CONVERT is more flexible in that you can format dates etc. Other than that, they are pretty much the same. If you don't care about the extended features, use CAST.

EDIT:

As noted by @beruic and @C-F in the comments below, there is possible loss of precision when an implicit conversion is used (that is one where you use neither CAST nor CONVERT). For further information, see CAST and CONVERT and in particular this graphic: SQL Server Data Type Conversion Chart. With this extra information, the original advice still remains the same. Use CAST where possible.

I wrote and released a small Nuget Package which can be used to print a PDF file to a printerdriver. It can also print to a XPS file or PDF file. Here is a link to it.

@Manuel was part way there. You can add the compiler option as well, like this:

If you have CMake 3.1.0+, this becomes even easier:

set(THREADS_PREFER_PTHREAD_FLAG ON)
find_package(Threads REQUIRED)
target_link_libraries(my_app PRIVATE Threads::Threads)

If you are using CMake 2.8.12+, you can simplify this to:

find_package(Threads REQUIRED)
if(THREADS_HAVE_PTHREAD_ARG)
  target_compile_options(my_app PUBLIC "-pthread")
endif()
if(CMAKE_THREAD_LIBS_INIT)
  target_link_libraries(my_app "${CMAKE_THREAD_LIBS_INIT}")
endif()

Older CMake versions may require:

find_package(Threads REQUIRED)
if(THREADS_HAVE_PTHREAD_ARG)
  set_property(TARGET my_app PROPERTY COMPILE_OPTIONS "-pthread")
  set_property(TARGET my_app PROPERTY INTERFACE_COMPILE_OPTIONS "-pthread")
endif()
if(CMAKE_THREAD_LIBS_INIT)
  target_link_libraries(my_app "${CMAKE_THREAD_LIBS_INIT}")
endif()

If you want to use one of the first two methods with CMake 3.1+, you will need set(THREADS_PREFER_PTHREAD_FLAG ON) there too.

SELECT DISTINCT(firstName), ID, LastName from tableName GROUP BY firstName

Would be the best bet IMO

In case anyone else comes across this problem, this was giving me issues due to the AJAX request and a normal form request being sent. I solved it with the following line:

<form onsubmit="submitfunc(); return false;">

The key there is the return false, which causes the form not to send. You could also just return false from inside of submitfunc(), but I find explicitly writing it to be clearer.

Since there is so much confusion about functionality of standard service accounts, I'll try to give a quick run down.

First the actual accounts:

• LocalService account (preferred)

  A limited service account that is very similar to Network Service and meant to run standard least-privileged services. However, unlike Network Service it accesses the network as an Anonymous user.

  • Name: NT AUTHORITY\LocalService
  • the account has no password (any password information you provide is ignored)
  • HKCU represents the LocalService user account
  • has minimal privileges on the local computer
  • presents anonymous credentials on the network
  • SID: S-1-5-19
  • has its own profile under the HKEY_USERS registry key (HKEY_USERS\S-1-5-19)

   

• NetworkService account

  Limited service account that is meant to run standard privileged services. This account is far more limited than Local System (or even Administrator) but still has the right to access the network as the machine (see caveat above).

  • NT AUTHORITY\NetworkService
  • the account has no password (any password information you provide is ignored)
  • HKCU represents the NetworkService user account
  • has minimal privileges on the local computer
  • presents the computer's credentials (e.g. MANGO$) to remote servers
  • SID: S-1-5-20
  • has its own profile under the HKEY_USERS registry key (HKEY_USERS\S-1-5-20)
  • If trying to schedule a task using it, enter NETWORK SERVICE into the Select User or Group dialog

   

• LocalSystem account (dangerous, don't use!)

  Completely trusted account, more so than the administrator account. There is nothing on a single box that this account cannot do, and it has the right to access the network as the machine (this requires Active Directory and granting the machine account permissions to something)

  • Name: .\LocalSystem (can also use LocalSystem or ComputerName\LocalSystem)
  • the account has no password (any password information you provide is ignored)
  • SID: S-1-5-18
  • does not have any profile of its own (HKCU represents the default user)
  • has extensive privileges on the local computer
  • presents the computer's credentials (e.g. MANGO$) to remote servers

   

Above when talking about accessing the network, this refers solely to SPNEGO (Negotiate), NTLM and Kerberos and not to any other authentication mechanism. For example, processing running as LocalService can still access the internet.

The general issue with running as a standard out of the box account is that if you modify any of the default permissions you're expanding the set of things everything running as that account can do. So if you grant DBO to a database, not only can your service running as Local Service or Network Service access that database but everything else running as those accounts can too. If every developer does this the computer will have a service account that has permissions to do practically anything (more specifically the superset of all of the different additional privileges granted to that account).

It is always preferable from a security perspective to run as your own service account that has precisely the permissions you need to do what your service does and nothing else. However, the cost of this approach is setting up your service account, and managing the password. It's a balancing act that each application needs to manage.

In your specific case, the issue that you are probably seeing is that the the DCOM or COM+ activation is limited to a given set of accounts. In Windows XP SP2, Windows Server 2003, and above the Activation permission was restricted significantly. You should use the Component Services MMC snapin to examine your specific COM object and see the activation permissions. If you're not accessing anything on the network as the machine account you should seriously consider using Local Service (not Local System which is basically the operating system).

In Windows Server 2003 you cannot run a scheduled task as

• NT_AUTHORITY\LocalService (aka the Local Service account), or
• NT AUTHORITY\NetworkService (aka the Network Service account).

That capability only was added with Task Scheduler 2.0, which only exists in Windows Vista/Windows Server 2008 and newer.

A service running as NetworkService presents the machine credentials on the network. This means that if your computer was called mango, it would present as the machine account MANGO$:

require_relative is a convenient subset of require

require_relative('path')

equals:

require(File.expand_path('path', File.dirname(__FILE__)))

if __FILE__ is defined, or it raises LoadError otherwise.

This implies that:

• require_relative 'a' and require_relative './a' require relative to the current file (__FILE__).

  This is what you want to use when requiring inside your library, since you don't want the result to depend on the current directory of the caller.

• eval('require_relative("a.rb")') raises LoadError because __FILE__ is not defined inside eval.

  This is why you can't use require_relative in RSpec tests, which get evaled.

The following operations are only possible with require:

• require './a.rb' requires relative to the current directory

• require 'a.rb' uses the search path ($LOAD_PATH) to require. It does not find files relative to current directory or path.

  This is not possible with require_relative because the docs say that path search only happens when "the filename does not resolve to an absolute path" (i.e. starts with / or ./ or ../), which is always the case for File.expand_path.

The following operation is possible with both, but you will want to use require as it is shorter and more efficient:

• require '/a.rb' and require_relative '/a.rb' both require the absolute path.

Reading the source

When the docs are not clear, I recommend that you take a look at the sources (toggle source in the docs). In some cases, it helps to understand what is going on.

require:

VALUE rb_f_require(VALUE obj, VALUE fname) {
  return rb_require_safe(fname, rb_safe_level());
}

require_relative:

VALUE rb_f_require_relative(VALUE obj, VALUE fname) {
    VALUE base = rb_current_realfilepath();
    if (NIL_P(base)) {
        rb_loaderror("cannot infer basepath");
    }
    base = rb_file_dirname(base);
    return rb_require_safe(rb_file_absolute_path(fname, base), rb_safe_level());
}

This allows us to conclude that

require_relative('path')

is the same as:

require(File.expand_path('path', File.dirname(__FILE__)))

because:

rb_file_absolute_path   =~ File.expand_path
rb_file_dirname1        =~ File.dirname
rb_current_realfilepath =~ __FILE__

Assuming you're the administrator of the machine, Ubuntu has granted you the right to sudo to run any command as any user.
Also assuming you did not restrict the rights in the pg_hba.conf file (in the /etc/postgresql/9.1/main directory), it should contain this line as the first rule:

# Database administrative login by Unix domain socket  
local   all             postgres                                peer

(About the file location: 9.1 is the major postgres version and main the name of your "cluster". It will differ if using a newer version of postgres or non-default names. Use the pg_lsclusters command to obtain this information for your version/system).

Anyway, if the pg_hba.conf file does not have that line, edit the file, add it, and reload the service with sudo service postgresql reload.

Then you should be able to log in with psql as the postgres superuser with this shell command:

sudo -u postgres psql

Once inside psql, issue the SQL command:

ALTER USER postgres PASSWORD 'newpassword';

In this command, postgres is the name of a superuser. If the user whose password is forgotten was ritesh, the command would be:

ALTER USER ritesh PASSWORD 'newpassword';

References: PostgreSQL 9.1.13 Documentation, Chapter 19. Client Authentication

Keep in mind that you need to type postgres with a single S at the end

If leaving the password in clear text in the history of commands or the server log is a problem, psql provides an interactive meta-command to avoid that, as an alternative to ALTER USER ... PASSWORD:

\password username

It asks for the password with a double blind input, then hashes it according to the password_encryption setting and issue the ALTER USER command to the server with the hashed version of the password, instead of the clear text version.

I´ve made a different solution, by eliminating the Control characters, which was my original problem.

It is better than putting in a list all the "special but good" chars

char[] arr = str.Where(c => !char.IsControl(c)).ToArray();    
str = new string(arr);

it´s simpler, so I think it´s better !

Vectors and matrices can only be of a single type and cbind and rbind on vectors will give matrices. In these cases, the numeric values will be promoted to character values since that type will hold all the values.

(Note that in your rbind example, the promotion happens within the c call:

> c(10, "[]", "[[1,2]]")
[1] "10"      "[]"      "[[1,2]]"

If you want a rectangular structure where the columns can be different types, you want a data.frame. Any of the following should get you what you want:

> x = data.frame(v1=c(10, 20), v2=c("[]", "[]"), v3=c("[[1,2]]","[[1,3]]"))
> x
  v1 v2      v3
1 10 [] [[1,2]]
2 20 [] [[1,3]]
> str(x)
'data.frame':   2 obs. of  3 variables:
 $ v1: num  10 20
 $ v2: Factor w/ 1 level "[]": 1 1
 $ v3: Factor w/ 2 levels "[[1,2]]","[[1,3]]": 1 2

or (using specifically the data.frame version of cbind)

> x = cbind.data.frame(c(10, 20), c("[]", "[]"), c("[[1,2]]","[[1,3]]"))
> x
  c(10, 20) c("[]", "[]") c("[[1,2]]", "[[1,3]]")
1        10            []                 [[1,2]]
2        20            []                 [[1,3]]
> str(x)
'data.frame':   2 obs. of  3 variables:
 $ c(10, 20)              : num  10 20
 $ c("[]", "[]")          : Factor w/ 1 level "[]": 1 1
 $ c("[[1,2]]", "[[1,3]]"): Factor w/ 2 levels "[[1,2]]","[[1,3]]": 1 2

or (using cbind, but making the first a data.frame so that it combines as data.frames do):

> x = cbind(data.frame(c(10, 20)), c("[]", "[]"), c("[[1,2]]","[[1,3]]"))
> x
  c.10..20. c("[]", "[]") c("[[1,2]]", "[[1,3]]")
1        10            []                 [[1,2]]
2        20            []                 [[1,3]]
> str(x)
'data.frame':   2 obs. of  3 variables:
 $ c.10..20.              : num  10 20
 $ c("[]", "[]")          : Factor w/ 1 level "[]": 1 1
 $ c("[[1,2]]", "[[1,3]]"): Factor w/ 2 levels "[[1,2]]","[[1,3]]": 1 2

For Swift 4.0, this got easier:

let defaults = UserDefaults.standard
//Set
defaults.set(passwordTextField.text, forKey: "Password")
//Get
let myPassword = defaults.string(forKey: "Password")

Note that, at least for Windows, htonl() is much slower than their intrinsic counterpart _byteswap_ulong(). The former is a DLL library call into ws2_32.dll, the latter is one BSWAP assembly instruction. Therefore, if you are writing some platform-dependent code, prefer using the intrinsics for speed:

#define htonl(x) _byteswap_ulong(x)

This may be especially important for .PNG image processing where all integers are saved in Big Endian with explanation "One can use htonl()..." {to slow down typical Windows programs, if you are not prepared}.

Add a backward slash in FIELDS TERMINATED BY '\;'

For Example:

FROM scn1_rcc1_agg as a LEFT OUTER JOIN scenario_activity_alert as b ON a.tran_uuid = b.activity_id;

I have tested it, and it worked.

var item = list[oldIndex];

list.RemoveAt(oldIndex);

if (newIndex > oldIndex) newIndex--; 
// the actual index could have shifted due to the removal

list.Insert(newIndex, item);

Put into Extension methods they look like:

    public static void Move<T>(this List<T> list, int oldIndex, int newIndex)
    {
        var item = list[oldIndex];

        list.RemoveAt(oldIndex);

        if (newIndex > oldIndex) newIndex--;
        // the actual index could have shifted due to the removal

        list.Insert(newIndex, item);
    }

    public static void Move<T>(this List<T> list, T item, int newIndex)
    {
        if (item != null)
        {
            var oldIndex = list.IndexOf(item);
            if (oldIndex > -1)
            {
                list.RemoveAt(oldIndex);

                if (newIndex > oldIndex) newIndex--;
                // the actual index could have shifted due to the removal

                list.Insert(newIndex, item);
            }
        }

    }

A branch is just a reference to a commit. Until you commit anything to the repository, you don't have any branches. You can see this in a non-bare repository as well.

$ mkdir repo
$ cd repo
$ git init
Initialized empty Git repository in /home/me/repo/.git/
$ git branch
$ touch foo
$ git add foo
$ git commit -m "new file"
1 file changed, 0 insertions(+), 0 deletions(-)
create mode 100644 foo
$ git branch
* master

You can use

git reset

to undo the recently added local files

 git reset file_name

to undo the changes for a specific file

Console applications will exit when the main function has finished running. A "return" will achieve this.

    static void Main(string[] args)
    {
        while (true)
        {
            Console.WriteLine("I'm running!");
            return; //This will exit the console application's running thread
        }
    }

If you're returning an error code you can do it this way, which is accessible from functions outside of the initial thread:

    System.Environment.Exit(-1);

See sys.exit. That function will quit your program with the given exit status.

Just follow 3 steps

1. Enable mode_rewrite using following command

   sudo a2enmod rewrite

Password will be asked. So enter your password

2. Update your 000-default.conf or default.conf file located at /etc/apache2/sites-available/ directory. you can not edit it directly. so use following command to open

   sudo gedit /etc/apache2/sites-available/000-default.conf

Or sudo gedit /etc/apache2/sites-available/default.conf

you will get

DocumentRoot /var/www/html

OR

DocumentRoot /var/www

line. Add following code after it.

<Directory /var/www/html/>
Options Indexes FollowSymLinks
AllowOverride All
Require all granted
</Directory>

Make user the directory tag path is same as shown in your file.

3. Restart your apache server using following command

   sudo service apache2 restart

You could have a look at this video about the list view. Its from last years Google IO and still the best walk-through on list views in my mind.

http://www.youtube.com/watch?v=wDBM6wVEO70

1. It inflates layouts (the xml files on your res/layout/ folder) into java Objects such as LinearLayout and other views.

2. Look at the video, will get you up to date with whats the use of the convert view, basically its a recycled view waiting to be reused by you, to avoid creating a new object and slowing down the scrolling of your list.

3. Allows you to reference you list-view from the adapter.

Corrected a few things and added an alternative select - delete as appropriate.

The answer is on the MSDN site:

The Save (Not Permitted) dialog box warns you that saving changes is not permitted because the changes you have made require the listed tables to be dropped and re-created.

The following actions might require a table to be re-created:

• Adding a new column to the middle of the table
• Dropping a column
• Changing column nullability
• Changing the order of the columns
• Changing the data type of a column

EDIT 1:

Additional useful informations from here:

To change the Prevent saving changes that require the table re-creation option, follow these steps:

1. Open SQL Server Management Studio (SSMS).
2. On the Tools menu, click Options.
3. In the navigation pane of the Options window, click Designers.
4. Select or clear the Prevent saving changes that require the table re-creation check box, and then click OK.

Note If you disable this option, you are not warned when you save the table that the changes that you made have changed the metadata structure of the table. In this case, data loss may occur when you save the table.

Risk of turning off the "Prevent saving changes that require table re-creation" option

Although turning off this option can help you avoid re-creating a table, it can also lead to changes being lost. For example, suppose that you enable the Change Tracking feature in SQL Server 2008 to track changes to the table. When you perform an operation that causes the table to be re-created, you receive the error message that is mentioned in the "Symptoms" section. However, if you turn off this option, the existing change tracking information is deleted when the table is re-created. Therefore, we recommend that you do not work around this problem by turning off the option.

For Spring Tool Suite I do:

File -> Open projects from File System

You can get the user's WindowsIdentity object under Windows Authentication by:

WindowsIdentity identity = HttpContext.Current.Request.LogonUserIdentity;

and then you can get the information about the user like identity.Name.

Please note you need to have HttpContext for these code.

I initially used IsNothing but I've been moving towards using Is Nothing in newer projects, mainly for readability. The only time I stick with IsNothing is if I'm maintaining code where that's used throughout and I want to stay consistent.

You need to be wary of XSS when doing stuff like this:

document.getElementById('<%= Label1.ClientID %>').style.display

The chances are that no-one will be able to tamper with the ClientID of Label1 in this instance, but just to be on the safe side you might want pass it's value through one of the AntiXss library's methods:

document.getElementById('<%= AntiXss.JavaScriptEncode(Label1.ClientID) %>').style.display

Try this->

EditText text = (EditText) findViewById(R.id.text_input);

Editable name = text.getText();

Editable is the return data type of getText() method it will handle both string and integer values

def rot13(s):
    lower_chars = ''.join(chr(c) for c in range (97,123)) #ASCII a-z
    upper_chars = ''.join(chr(c) for c in range (65,91)) #ASCII A-Z
    lower_encode = lower_chars[13:] + lower_chars[:13] #shift 13 bytes
    upper_encode = upper_chars[13:] + upper_chars[:13] #shift 13 bytes
    output = "" #outputstring
    for c in s:
        if c in lower_chars:
                output = output + lower_encode[lower_chars.find(c)]
        elif c in upper_chars:
            output = output + upper_encode[upper_chars.find(c)]
        else:
            output = output + c
    return output

Another solution with shifting. Maybe this code helps other people to understand rot13 better. Haven't tested it completely.

If you have some methods which are not synchronized and are accessing and changing the instance variables. In your example:

 private int a;
 private int b;

any number of threads can access these non synchronized methods at the same time when other thread is in the synchronized method of the same object and can make changes to instance variables. For e.g :-

 public void changeState() {
      a++;
      b++;
    }

You need to avoid the scenario that non synchronized methods are accessing the instance variables and changing it otherwise there is no point of using synchronized methods.

In the below scenario:-

class X {

        private int a;
        private int b;

        public synchronized void addA(){
            a++;
        }

        public synchronized void addB(){
            b++;
        }
     public void changeState() {
          a++;
          b++;
        }
    }

Only one of the threads can be either in addA or addB method but at the same time any number of threads can enter changeState method. No two threads can enter addA and addB at same time(because of Object level locking) but at same time any number of threads can enter changeState.

Try to give permission to full control the python folder.

Find the python root directory-->right button click-->properties-->security-->edit-->give users Full Control-->yes and wait the process finished.

It works for me.

You can try this:

return &Type();

So, this is definitely not the "shorter" version - and one might digress if "shortest" and "Pythonic" are actually compatible.

But if one needs this pattern often, just put the logic in to a 10-liner generator - and get any meta-data related to an element's position directly on the for call. Another advantage here is that it will work wit an arbitrary iterable, not only Sequences.

_sentinel = object()

def iter_check_last(iterable):
    iterable = iter(iterable)
    current_element = next(iterable, _sentinel)
    while current_element is not _sentinel:
        next_element = next(iterable, _sentinel)
        yield (next_element is _sentinel, current_element)
        current_element = next_element

In [107]: for is_last, el in iter_check_last(range(3)):
     ...:     print(is_last, el)
     ...: 
     ...: 
False 0
False 1
True 2

You can use the --table or -t option, which will output a nice looking set of results

echo 'desc table_name' | mysql -uroot database -t

or some other method to pass a query to mysql, like:

mysql -uroot table_name --table < /tmp/somequery.sql

output:

Use .find() method

$(t).find("td:eq(1)");

td:eq(x) // x is index of child you want to retrieve. eq(1) means equal to 1. //1 denote second element

Try:

ArrayListname.get(index);

Where index is the position in the index and ArrayListname is the name of the Arraylist as in your case is mainList.

If you installed gradle with homebrew, then the path is:

/usr/local/Cellar/gradle/X.X/libexec

Where X.X is the version of gradle (currently 2.1)

You need to have your variables exported. So for example in Linux:

export EnvironmentVariableName=foo

Unexported variables are empty in CMAKE.

Can even work with Associative Arrays.. for example in a class.

class Test {

    const 
        CAN = [
            "can bark", "can meow", "can fly"
        ],
        ANIMALS = [
            self::CAN[0] => "dog",
            self::CAN[1] => "cat",
            self::CAN[2] => "bird"
        ];

    static function noParameter() {
        return self::ANIMALS[self::CAN[0]];
    }

    static function withParameter($which, $animal) {
        return "who {$which}? a {$animal}.";
    }

}

echo Test::noParameter() . "s " . Test::CAN[0] . ".<br>";
echo Test::withParameter(
    array_keys(Test::ANIMALS)[2], Test::ANIMALS["can fly"]
);

// dogs can bark.
// who can fly? a bird.

IF EXISTS(SELECT 1 FROM sys.types WHERE name = 'Person' AND is_table_type = 1 AND SCHEMA_ID('VAB') = schema_id)

    ,LastName               VARCHAR(255)
    ,PreferredName          VARCHAR(255)
);

1) Locate server.xml in {Tomcat installation folder}\ conf \ 2) Find following similar statement

       <!-- Define a non-SSL HTTP/1.1 Connector on port 8180 -->
      <Connector port="8080" maxHttpHeaderSize="8192"
           maxThreads="150" minSpareThreads="25" maxSpareThreads="75"
           enableLookups="false" redirectPort="8443" acceptCount="100"
           connectionTimeout="20000" disableUploadTimeout="true" />

For example

<Connector port="8181" protocol="HTTP/1.1" 
           connectionTimeout="20000" 
           redirectPort="8443" />

Edit and save the server.xml file. Restart Tomcat. Done

You can't just return an array of objects because there's nothing telling React how to render that. You'll need to return an array of components or elements like:

render: function() {
  return (
    <span>
      // This will go through all the elements in arrayFromJson and
      // render each one as a <SomeComponent /> with data from the object
      {this.state.arrayFromJson.map(function(object) {
        return (
          <SomeComponent key={object.id} data={object} />
        );
      })}
    </span>
  );
}

One lesson from my experience:

offset floor(random() * N) limit 1 is not faster than order by random() limit 1.

I thought the offset approach would be faster because it should save the time of sorting in Postgres. Turns out it wasn't.

A direct interpretation

An IntPtr is an integer which is the same size as a pointer.

You can use IntPtr to store a pointer value in a non-pointer type. This feature is important in .NET since using pointers is highly error prone and therefore illegal in most contexts. By allowing the pointer value to be stored in a "safe" data type, plumbing between unsafe code segments may be implemented in safer high-level code -- or even in a .NET language that doesn't directly support pointers.

The size of IntPtr is platform-specific, but this detail rarely needs to be considered, since the system will automatically use the correct size.

The name "IntPtr" is confusing -- something like Handle might have been more appropriate. My initial guess was that "IntPtr" was a pointer to an integer. The MSDN documentation of IntPtr goes into somewhat cryptic detail without ever providing much insight about the meaning of the name.

An alternative perspective

An IntPtr is a pointer with two limitations:

1. It cannot be directly dereferenced
2. It doesn't know the type of the data that it points to.

In other words, an IntPtr is just like a void* -- but with the extra feature that it can (but shouldn't) be used for basic pointer arithmetic.

In order to dereference an IntPtr, you can either cast it to a true pointer (an operation which can only be performed in "unsafe" contexts) or you can pass it to a helper routine such as those provided by the InteropServices.Marshal class. Using the Marshal class gives the illusion of safety since it doesn't require you to be in an explicit "unsafe" context. However, it doesn't remove the risk of crashing which is inherent in using pointers.

For example:

sqlplus -s admin/password << EOF
whenever sqlerror exit sql.sqlcode;
set echo off 
set heading off

@pl_script_1.sql
@pl_script_2.sql

exit;
EOF

What is the difference between sorted(list) vs list.sort()?

• list.sort mutates the list in-place & returns None
• sorted takes any iterable & returns a new list, sorted.

sorted is equivalent to this Python implementation, but the CPython builtin function should run measurably faster as it is written in C:

def sorted(iterable, key=None):
    new_list = list(iterable)    # make a new list
    new_list.sort(key=key)       # sort it
    return new_list              # return it

when to use which?

• Use list.sort when you do not wish to retain the original sort order (Thus you will be able to reuse the list in-place in memory.) and when you are the sole owner of the list (if the list is shared by other code and you mutate it, you could introduce bugs where that list is used.)
• Use sorted when you want to retain the original sort order or when you wish to create a new list that only your local code owns.

Can a list's original positions be retrieved after list.sort()?

No - unless you made a copy yourself, that information is lost because the sort is done in-place.

"And which is faster? And how much faster?"

To illustrate the penalty of creating a new list, use the timeit module, here's our setup:

import timeit
setup = """
import random
lists = [list(range(10000)) for _ in range(1000)]  # list of lists
for l in lists:
    random.shuffle(l) # shuffle each list
shuffled_iter = iter(lists) # wrap as iterator so next() yields one at a time
"""

And here's our results for a list of randomly arranged 10000 integers, as we can see here, we've disproven an older list creation expense myth:

Python 2.7

>>> timeit.repeat("next(shuffled_iter).sort()", setup=setup, number = 1000)
[3.75168503401801, 3.7473005310166627, 3.753129180986434]
>>> timeit.repeat("sorted(next(shuffled_iter))", setup=setup, number = 1000)
[3.702025591977872, 3.709248117986135, 3.71071034099441]

Python 3

>>> timeit.repeat("next(shuffled_iter).sort()", setup=setup, number = 1000)
[2.797430992126465, 2.796825885772705, 2.7744789123535156]
>>> timeit.repeat("sorted(next(shuffled_iter))", setup=setup, number = 1000)
[2.675589084625244, 2.8019039630889893, 2.849375009536743]

After some feedback, I decided another test would be desirable with different characteristics. Here I provide the same randomly ordered list of 100,000 in length for each iteration 1,000 times.

import timeit
setup = """
import random
random.seed(0)
lst = list(range(100000))
random.shuffle(lst)
"""

I interpret this larger sort's difference coming from the copying mentioned by Martijn, but it does not dominate to the point stated in the older more popular answer here, here the increase in time is only about 10%

>>> timeit.repeat("lst[:].sort()", setup=setup, number = 10000)
[572.919036605, 573.1384446719999, 568.5923951]
>>> timeit.repeat("sorted(lst[:])", setup=setup, number = 10000)
[647.0584738299999, 653.4040515829997, 657.9457361929999]

I also ran the above on a much smaller sort, and saw that the new sorted copy version still takes about 2% longer running time on a sort of 1000 length.

Poke ran his own code as well, here's the code:

setup = '''
import random
random.seed(12122353453462456)
lst = list(range({length}))
random.shuffle(lst)
lists = [lst[:] for _ in range({repeats})]
it = iter(lists)
'''
t1 = 'l = next(it); l.sort()'
t2 = 'l = next(it); sorted(l)'
length = 10 ** 7
repeats = 10 ** 2
print(length, repeats)
for t in t1, t2:
    print(t)
    print(timeit(t, setup=setup.format(length=length, repeats=repeats), number=repeats))

He found for 1000000 length sort, (ran 100 times) a similar result, but only about a 5% increase in time, here's the output:

10000000 100
l = next(it); l.sort()
610.5015971539542
l = next(it); sorted(l)
646.7786222379655

Conclusion:

A large sized list being sorted with sorted making a copy will likely dominate differences, but the sorting itself dominates the operation, and organizing your code around these differences would be premature optimization. I would use sorted when I need a new sorted list of the data, and I would use list.sort when I need to sort a list in-place, and let that determine my usage.

You can also customize the card theme globally with ThemeData.cardTheme:

MaterialApp(
  title: 'savvy',
  theme: ThemeData(
    cardTheme: CardTheme(
      shape: RoundedRectangleBorder(
        borderRadius: const BorderRadius.all(
          Radius.circular(8.0),
        ),
      ),
    ),
    // ...

If you are receiving that error even after creating a new user and assigning them the database previledges, then the one last thing to look at is to check if the users have been assigned the preiveledges in the database.

To do this log into to your mysql(This is presumably its the application that has restricted access to the database but you as a root can be ablr to access your database table via mysql -u user -p)

commands to apply

mysql -u root -p 

password: (provide your database credentials)

on successful login

type

use mysql;

from this point check each users priveledges if it is enabled from the db table as follows

select User,Grant_priv,Host from db;

if the values of the Grant_priv col for the created user is N update that value to Y with the following command

UPDATE db SET Grant_priv = "Y" WHERE User= "your user";

with that now try accessing the app and making a transaction with the database.

It seems you can provide just the local image name, assuming it is in the same folder...

It suffices like:

background-image: url("img1.png")

I understand this is quite an old question. But would like to clarify that:

Date d = new Date() 

is depriciated in the current versions of Java. The recommended way is using a calendar object. For eg:

Calendar cal = Calendar.getInstance();
Date currentTime = cal.getTime();

I hope this will help people who may refer this question in future. Thank you all.

Match the .env file and the config.php file with your username and password and your hostname in the database settings.if they are not equal,relation will not connect.

Since this is still very relevant, the first Google hit and I just spend some time figuring this out, I'll post my (working in Python 3) solution:

testdict = {'one'   : '1',
            'two'   : '2',
            'three' : '3',
            'four'  : '4'
            }

value = '2'

[key for key in testdict.items() if key[1] == value][0][0]

Out[1]: 'two'

It will give you the first value that matches.

svn co svn://path destination

To specify current directory, use a "." for your destination directory:

svn checkout file:///home/landonwinters/svn/waterproject/trunk .

Looking at your example, I think ArrayBlockingQueue (or its siblings) may be of use. They look after the synchronisation for you, so threads can write to the queue or peek/take without additional synchronisation work on your part.

Try calling setWillNotDraw(false) from surfaceCreated:

public void surfaceCreated(SurfaceHolder holder) {
    try {
        setWillNotDraw(false); 
        mycam.setPreviewDisplay(holder);
        mycam.startPreview();
    } catch (Exception e) {
        e.printStackTrace();

You can call up the color picker from any Cocoa application (TextEdit, Mail, Keynote, Pages, etc.) by hitting Shift-Command-C

The following article explains more about using Mac OS's Color Picker.

You can try:

print('Next Date ' . date('Y-m-d', strtotime('-1 day', strtotime($date_raw))));

toISOString() will return current UTC time only not the current local time. If you want to get the current local time in yyyy-MM-ddTHH:mm:ss.SSSZ format then you should get the current time using following two methods

Method 1:

document.write(new Date(new Date().toString().split('GMT')[0]+' UTC').toISOString());

Method 2:

document.write(new Date(new Date().getTime() - new Date().getTimezoneOffset() * 60000).toISOString());

Because you didn't specify the Header.

I've added an extended example:

var request = (HttpWebRequest)WebRequest.Create(strServer + strURL.Split('&')[1].ToString());

Header(ref request, p_Method);

And the method Header:

private void Header(ref HttpWebRequest p_request, string p_Method)
{
    p_request.ContentType = "application/x-www-form-urlencoded";
    p_request.Method = p_Method;
    p_request.UserAgent = "Mozilla/4.0 (compatible; MSIE 6.0; Windows CE)";
    p_request.Host = strServer.Split('/')[2].ToString();
    p_request.Accept = "*/*";
    if (String.IsNullOrEmpty(strURLReferer))
    {
        p_request.Referer = strServer;
    }
    else
    {
        p_request.Referer = strURLReferer;
    }
    p_request.Headers.Add("Accept-Language", "en-us\r\n");
    p_request.Headers.Add("UA-CPU", "x86 \r\n");
    p_request.Headers.Add("Cache-Control", "no-cache\r\n");
    p_request.KeepAlive = true;
}

1. Install dotenv as devDependencies:

npm i --save-dev dotenv

2. Create a .env file in the root directory:

my-react-app/
|- node-modules/
|- public/
|- src/
|- .env
|- .gitignore
|- package.json
|- package.lock.json.
|- README.md

3. Update the .env file like below & REACT_APP_ is the compulsory prefix for the variable name.

REACT_APP_BASE_URL=http://localhost:8000
REACT_APP_API_KEY=YOUR-API-KEY

4. [ Optional but Good Practice ] Now you can create a configuration file to store the variables and export the variable so can use it from others file.

For example, I've create a file named base.js and update it like below:

export const BASE_URL = process.env.REACT_APP_BASE_URL;
export const API_KEY = process.env.REACT_APP_API_KEY;

5. Or you can simply just call the environment variable in your JS file in the following way:

process.env.REACT_APP_BASE_URL

Generate a Windows command file (batch) for installing extensions:

for /F "tokens=*" %i in ('code --list-extensions')
   do @echo call code --install-extension %i >> install.cmd

If you want a real timer you need to use the date object.

Calculate the difference.

Format your string.

window.onload=function(){
      var start=Date.now(),r=document.getElementById('r');
      (function f(){
      var diff=Date.now()-start,ns=(((3e5-diff)/1e3)>>0),m=(ns/60)>>0,s=ns-m*60;
      r.textContent="Registration closes in "+m+':'+((''+s).length>1?'':'0')+s;
      if(diff>3e5){
         start=Date.now()
      }
      setTimeout(f,1e3);
      })();
}

Example

If you make multiDexEnabled = true in defaultConfig of the app, you will get the desired result.

defaultConfig {
    minSdkVersion 14
    targetSdkVersion 22
    multiDexEnabled = true
}

Why use int at all?

Apple uses int because for a loop control variable (which is only used to control the loop iterations) int datatype is fine, both in datatype size and in the values it can hold for your loop. No need for platform dependent datatype here. For a loop control variable even a 16-bit int will do most of the time.

Apple uses NSInteger for a function return value or for a function argument because in this case datatype [size] matters, because what you are doing with a function is communicating/passing data with other programs or with other pieces of code; see the answer to When should I be using NSInteger vs int? in your question itself...

they [Apple] use NSInteger (or NSUInteger) when passing a value as an argument to a function or returning a value from a function.

Add white-space: nowrap;:

.garage-title {
    clear: both;
    display: inline-block;
    overflow: hidden;
    white-space: nowrap;
}

Best Solution to wait AsynMethod till complete the task is

var result = Task.Run(async() => await yourAsyncMethod()).Result;

All you have to do is create a subset of your dataframe where the isin method evaluates to False:

df = df[df['Column Name'].isin(['Value']) == False]

DateFormat formatter = new SimpleDateFormat("yyyy-MM-dd");

Date date = formatter.parse(dateString);

Timestamp timestamp = new Timestamp(date.getTime());

System.out.println(timestamp);

I want to add to the answers above that it becomes a little more difficult if Jenkins authorization is enabled.

After enabling it I got an error message that anonymous user needs read permission.

I saw two possible solutions:

1: Changing my hook to:

curl --user name:passwd -s http://domain?token=whatevertokenuhave

2: setting project based authorization.

The former solutions has the disadvantage that I had to expose my passwd in the hook file. Unacceptable in my case.

The second works for me. In the global auth settings I had to enable Overall>Read for Anonymous user. In the project I wanted to trigger I had to enable Job>Build and Job>Read for Anonymous.

This is still not a perfect solution because now you can see the project in Jenkins without login. There might be an even better solution using the former approach with http login but I haven't figured it out.

You can use addBatch and executeBatch for batch insert in java See the Example : Batch Insert In Java

To place an emphasis on what everyone else has been saying var foo in top level does not create a global variable. If you want a global variable then write global.foo. but we all know globals are evil.

If you are someone who uses globals like that in a node.js project I was on I would refactor them away for as there are just so few use cases for this (There are a few exceptions but this isn't one).

// Declare application
var app = require('express').createServer();

// Declare usefull stuff for DB purposes
var mongoose = require('mongoose');
var Schema = mongoose.Schema;
var ObjectId = Schema.ObjectId;

require('./models/car.js').make(Schema, mongoose);

in car.js

function make(Schema, mongoose) {
    // Define Car model
    CarSchema = new Schema({
      brand        : String,
      type : String
    });
    mongoose.model('Car', CarSchema);
}

module.exports.make = make;

The answer from brad.v is incorrect! It won't give you a concatenated string.

Here's the correct code, almost like brad.v's but with one important change:

DECLARE @results VarChar(1000)
  SELECT @results = CASE
     WHEN @results IS NULL THEN CONVERT( VarChar(20), [StudentId])
     ELSE @results + ', ' + CONVERT( VarChar(20), [StudentId])
  END
FROM Student WHERE condition = abc;

See the difference? :) brad.v please fix your answer, I can't do anything to correct it or comment on it 'cause my reputation here is zero. I guess I can remove mine after you fix yours. Thanks!

A dynamic $HOME/.zshrc solution, if you're like me ie. Linux @ work; MBP/A @ home

if [[ $(uname) == "Darwin" ]]; then export OSX=1; fi
if [[ $(uname) ==  "Linux" ]]; then export LINUX=1; fi

if [[ -n $OSX ]]; then
        export JAVA_HOME=$(/usr/libexec/java_home)
else
        export JAVA_HOME=/usr/lib/jvm/default-java
fi

Filing this under #wow

Turns out that IIS has different levels of compression configurable from 1-9.

Some of my dynamic SOAP requests have been getting out of control recently. With the uncompressed SOAP being about 14MB and compressed 3MB.

I noticed that in Fiddler when I compressed my request under Transformer it came to about 470KB instead of the 3MB - so I figured there must be some way to get better compression.

Eventually found this very informative blog post

http://weblogs.asp.net/owscott/iis-7-compression-good-bad-how-much

I went ahead and ran this commnd (followed by iisreset):

C:\Windows\System32\Inetsrv\Appcmd.exe set config -section:httpCompression -[name='gzip'].staticCompressionLevel:9 -[name='gzip'].dynamicCompressionLevel:9

Changed dynamic level up to 9 and now my compressed soap matches what Fiddler gave me - and it about 1/7th the size of the existing compressed file.

Milage will vary, but for SOAP this is a massive massive improvement.

you can use the following.

$("#selector").datepicker({
    maxDate: 0
});

It works fine with Salesforce REST API query datetime formats

DateTime now = DateTime.UtcNow;
string startDate = now.AddDays(-5).ToString("yyyy-MM-ddTHH\\:mm\\:ssZ");   
string endDate = now.ToString("yyyy-MM-ddTHH\\:mm\\:ssZ");  
//REST service Query 
string salesforceUrl= https://csxx.salesforce.com//services/data/v33.0/sobjects/Account/updated/?start=" + startDate + "&end=" + endDate;

// https://csxx.salesforce.com/services/data/v33.0/sobjects/Account/updated/?start=2015-03-10T15:15:57Z&end=2015-03-15T15:15:57Z

It returns the results from Salesforce without any issues.

TL;DR: You should add a JProperty to a JObject. Simple. The index query returns a JValue, so figure out how to get the JProperty instead :)

The accepted answer is not answering the question as it seems. What if I want to specifically add a JProperty after a specific one? First, lets start with terminologies which really had my head worked up.

• JToken = The mother of all other types. It can be A JValue, JProperty, JArray, or JObject. This is to provide a modular design to the parsing mechanism.
• JValue = any Json value type (string, int, boolean).
• JProperty = any JValue or JContainer (see below) paired with a name (identifier). For example "name":"value".
• JContainer = The mother of all types which contain other types (JObject, JValue).
• JObject = a JContainer type that holds a collection of JProperties
• JArray = a JContainer type that holds a collection JValue or JContainer.

Now, when you query Json item using the index [], you are getting the JToken without the identifier, which might be a JContainer or a JValue (requires casting), but you cannot add anything after it, because it is only a value. You can change it itself, query more deep values, but you cannot add anything after it for example.

What you actually want to get is the property as whole, and then add another property after it as desired. For this, you use JOjbect.Property("name"), and then create another JProperty of your desire and then add it after this using AddAfterSelf method. You are done then.

This is the code I modified.

public class Program
{
  public static void Main()
  {
    try
    {
      string jsonText = @"
      {
        ""food"": {
          ""fruit"": {
            ""apple"": {
              ""colour"": ""red"",
              ""size"": ""small""
            },
            ""orange"": {
              ""colour"": ""orange"",
              ""size"": ""large""
            }
          }
        }
      }";

      var foodJsonObj = JObject.Parse(jsonText);
      var bananaJson = JObject.Parse(@"{ ""banana"" : { ""colour"": ""yellow"", ""size"": ""medium""}}");

      var fruitJObject = foodJsonObj["food"]["fruit"] as JObject;
      fruitJObject.Property("orange").AddAfterSelf(new JProperty("banana", fruitJObject));

      Console.WriteLine(foodJsonObj.ToString());
    }
    catch (Exception ex)
    {
      Console.WriteLine(ex.GetType().Name + ": " + ex.Message);
    }
  }
}

The official link no longer offers the original source code. The official link and casual google searches will land you with open jdk. Open jdk causes problems with android build unless the build script files are modified. The original package can be found here:

For those who use ASP.NET Identity 2.1 and have changed the primary key from the default string to either int or Guid, if you're still getting

EntityType 'xxxxUserLogin' has no key defined. Define the key for this EntityType.

EntityType 'xxxxUserRole' has no key defined. Define the key for this EntityType.

you probably just forgot to specify the new key type on IdentityDbContext:

public class AppIdentityDbContext : IdentityDbContext<
    AppUser, AppRole, int, AppUserLogin, AppUserRole, AppUserClaim>
{
    public AppIdentityDbContext()
        : base("MY_CONNECTION_STRING")
    {
    }
    ......
}

If you just have

public class AppIdentityDbContext : IdentityDbContext
{
    ......
}

or even

public class AppIdentityDbContext : IdentityDbContext<AppUser>
{
    ......
}

you will get that 'no key defined' error when you are trying to add migrations or update the database.

This has been discussed in many posts but still I could not figure out a solution with:

android:focusable="false"
android:focusableInTouchMode="false"
android:focusableInTouchMode="false"

Below solution will work with any of the ui components : Button, ImageButtons, ImageView, Textview. LinearLayout, RelativeLayout clicks inside a listview cell and also will respond to onItemClick:

Adapter class - getview():

    @Override
        public View getView(int position, View convertView, ViewGroup parent) {
            View view = convertView;
            if (view == null) {
                view = lInflater.inflate(R.layout.my_ref_row, parent, false);
            }
            final Organization currentOrg = organizationlist.get(position).getOrganization();

            TextView name = (TextView) view.findViewById(R.id.name);
            Button btn = (Button) view.findViewById(R.id.btn_check);
            btn.setOnClickListener(new OnClickListener() {

                @Override
                public void onClick(View v) {
                    context.doSelection(currentOrg);

                }
            });

       if(currentOrg.isSelected()){
            btn.setBackgroundResource(R.drawable.sub_search_tick);
        }else{
            btn.setBackgroundResource(R.drawable.sub_search_tick_box);
        }

    }

In this was you can get the button clicked object to the activity. (Specially when you want the button to act as a check box with selected and non-selected states):

    public void doSelection(Organization currentOrg) {
        Log.e("Btn clicked ", currentOrg.getOrgName());
        if (currentOrg.isSelected() == false) {
            currentOrg.setSelected(true);
        } else {
            currentOrg.setSelected(false);
        }
        adapter.notifyDataSetChanged();

    }

Remove "strictNullChecks": true from "compilerOptions" or set it to false in the tsconfig.json file of your Ng app. These errors will go away like anything and your app would compile successfully.

Disclaimer: This is just a workaround. This error appears only when the null checks are not handled properly which in any case is not a good way to get things done.

No there is no built-in String method. You can convert it to a char array, sort it using Arrays.sort and convert that back into a String.

String test= "edcba";
char[] ar = test.toCharArray();
Arrays.sort(ar);
String sorted = String.valueOf(ar);

Or, when you want to deal correctly with locale-specific stuff like uppercase and accented characters:

import java.text.Collator;
import java.util.Arrays;
import java.util.Comparator;
import java.util.Locale;

public class Test
{
  public static void main(String[] args)
  {
    Collator collator = Collator.getInstance(new Locale("fr", "FR"));
    String original = "éDedCBcbAàa";
    String[] split = original.split("");
    Arrays.sort(split, collator);
    String sorted = "";
    for (int i = 0; i < split.length; i++)
    {
      sorted += split[i];
    }
    System.out.println(sorted); // "aAàbBcCdDeé"
  }
}

None of the above solutions worked for me, however instead I wrapped my content in a div (#outer-wrap) and then used the following CSS:

body {
   overflow: hidden;
}
#outer-wrap {
    -webkit-overflow-scrolling: touch;
     height: 100vh;
     overflow: auto;
}

Obviously only works in browsers that support viewport widths/heights of course.

Based on the Roman's most upvoted comment above, here is my implementation, Including "download as" and "retries" mechanism:

def download(url: str, file_path='', attempts=2):
    """Downloads a URL content into a file (with large file support by streaming)

    :param url: URL to download
    :param file_path: Local file name to contain the data downloaded

    :return: New file path. Empty string if the download failed
    """
    if not file_path:
        file_path = os.path.realpath(os.path.basename(url))
    logger.info(f'Downloading {url} content to {file_path}')
    url_sections = urlparse(url)
    if not url_sections.scheme:
        logger.debug('The given url is missing a scheme. Adding http scheme')
        url = f'http://{url}'
        logger.debug(f'New url: {url}')
    for attempt in range(1, attempts+1):
        try:
            if attempt > 1:
                time.sleep(10)  # 10 seconds wait time between downloads
            with requests.get(url, stream=True) as response:

                        out_file.write(chunk)
                logger.info('Download finished successfully')
                return file_path

No. The method for appending an entire sequence is list.extend().

>>> L = [1, 2]
>>> L.extend((3, 4, 5))
>>> L
[1, 2, 3, 4, 5]

SELECT CAST(CAST(@DateField As Date) As DateTime) + CAST(CAST(@TimeField As Time) As DateTime)

The translation you are addressing has to do with Map Projection, which is how the spherical surface of our world is translated into a 2 dimensional rendering. There are multiple ways (projections) to render the world on a 2-D surface.

If your maps are using just a specific projection (Mercator being popular), you should be able to find the equations, some sample code, and/or some library (e.g. one Mercator solution - Convert Lat/Longs to X/Y Co-ordinates. If that doesn't do it, I'm sure you can find other samples - https://stackoverflow.com/search?q=mercator. If your images aren't map(s) using a Mercator projection, you'll need to determine what projection it does use to find the right translation equations.

If you are trying to support multiple map projections (you want to support many different maps that use different projections), then you definitely want to use a library like PROJ.4, but again I'm not sure what you'll find for Javascript or PHP.

You have to create a derived table for the distinct columns and then query the count from that table:

SELECT COUNT(*) 
FROM (SELECT DISTINCT column1,column2
      FROM  tablename  
      WHERE condition ) as dt

Here dt is a derived table.

pprofile

line_profiler (already presented here) also inspired pprofile, which is described as:

Line-granularity, thread-aware deterministic and statistic pure-python profiler

It provides line-granularity as line_profiler, is pure Python, can be used as a standalone command or a module, and can even generate callgrind-format files that can be easily analyzed with [k|q]cachegrind.

vprof

There is also vprof, a Python package described as:

[...] providing rich and interactive visualizations for various Python program characteristics such as running time and memory usage.

You can do it with animate function in jQuery.

$({ countNum: $('.code').html() }).animate({ countNum: 4000 }, {
    duration: 8000,
    easing: 'linear',
    step: function () {
        $('.yourelement').html(Math.floor(this.countNum));
    },
    complete: function () {
        $('.code').html(this.countNum);
        //alert('finished');
   }
});

Demo

andyras is completely correct. One minor addition, try this (for example)

plot 'ls.dat' using 4:xtic(1)

This will keep your datafile in the correct order, but also preserve your version tic labels on the x-axis.
