Programs & Examples On #Asyncsocket

Plug in your network cable into a switch which has no other connection/cables. That should work imho.

I would just like to add that if the String is originally encoded using the wrong encoding it might be impossible to change it to another encoding without errors. The question does not state that the conversion here is made from wrong encoding to correct encoding but I personally stumbled to this question just because of this situation so just a heads up for others as well.

This answer in other question gives an explanation why the conversion does not always yield correct results https://stackoverflow.com/a/2623793/4702806

I found a solution to this on github for select2

https://github.com/ivaynberg/select2/issues/1436

For bootstrap 3, the solution is:

$.fn.modal.Constructor.prototype.enforceFocus = function() {};

Bootstrap 4 renamed the enforceFocus method to _enforceFocus, so you'll need to patch that instead:

$.fn.modal.Constructor.prototype._enforceFocus = function() {};

Explanation copied from link above:

Bootstrap registers a listener to the focusin event which checks whether the focused element is either the overlay itself or a descendent of it - if not it just refocuses on the overlay. With the select2 dropdown being attached to the body this effectively prevents you from entering anything into the the textfield.

You can quickfix this by overwriting the enforceFocus function which registers the event on the modal

I had the same problem as you.

I did git status git fetch git pull, but my branch was still behind to origin. I had folders and files pushed to remote and I saw the files on the web, but on my local they were missing.

Finally, these commands updated all the files and folders on my local:

git fetch --all
git reset --hard origin/master 

or if you want a branch

git checkout your_branch_name_here
git reset --hard origin/your_branch_name_here

The default is 20 minutes. http://msdn.microsoft.com/en-us/library/h6bb9cz9(v=vs.80).aspx

and, for completeness and with regards to this question asking about changing string columns only, there's mutate_if:

data <- cbind(stringVar = sample(c("foo","bar"),10,replace=TRUE),
              data.frame(matrix(sample(1:40), 10, 10, dimnames = list(1:10, LETTERS[1:10]))),stringsAsFactors=FALSE)     

factoredData = data %>% mutate_if(is.character,funs(factor(.)))

The problem is probably coming from the fact that Date is deprecated.

Consider using

java.util.Calendar

or

Joda-Time

Edit 2015:

Java 8 and later has built-in the new java.time package, which is similar to Joda-Time.

The first constructor in the header should not end with a semicolon. #include <string> is missing in the header. string is not qualified with std:: in the .cpp file. Those are all simple syntax errors. More importantly: you are not using references, when you should. Also the way you use the ifstream is broken. I suggest learning C++ before trying to use it.

Let's fix this up:

//polygone.h
# if !defined(__POLYGONE_H__)
# define __POLYGONE_H__

#include <iostream>
#include <string>    

class Polygone {
public:
  // declarations have to end with a semicolon, definitions do not
  Polygone(){} // why would we needs this?
  Polygone(const std::string& fichier);
};

# endif

and

//polygone.cc
// no need to include things twice
#include "polygone.h"
#include <fstream>


Polygone::Polygone(const std::string& nom)
{
  std::ifstream fichier (nom, ios::in);


  if (fichier.is_open())
  {
    // keep the scope as tiny as possible
    std::string line;
    // getline returns the stream and streams convert to booleans
    while ( std::getline(fichier, line) )
    {
      std::cout << line << std::endl;
    }
  }
  else
  {
    std::cerr << "Erreur a l'ouverture du fichier" << std::endl;
  }
}

Follow these instructions,

1. First make sure you have notepad++ installed on your system and that it is the default programme to open .txt files.

2. Then Install gitpad on your system. Note the last I checked the download link was broken, so download it from here as explained.

Then while committing you should see your favorite text editor popping up.

i had the same issue and tried a few of the given solutions but it still didn't work. all i did was to run the "npx yarn" command in the root folder of my project and that was it.

In v2.0 of the Graph API, calling /me/friends returns the person's friends who also use the app.

In addition, in v2.0, you must request the user_friends permission from each user. user_friends is no longer included by default in every login. Each user must grant the user_friends permission in order to appear in the response to /me/friends. See the Facebook upgrade guide for more detailed information, or review the summary below.

The /me/friendlists endpoint and user_friendlists permission are not what you're after. This endpoint does not return the users friends - its lets you access the lists a person has made to organize their friends. It does not return the friends in each of these lists. This API and permission is useful to allow you to render a custom privacy selector when giving people the opportunity to publish back to Facebook.

If you want to access a list of non-app-using friends, there are two options:

1. If you want to let your people tag their friends in stories that they publish to Facebook using your App, you can use the /me/taggable_friends API. Use of this endpoint requires review by Facebook and should only be used for the case where you're rendering a list of friends in order to let the user tag them in a post.

2. If your App is a Game AND your Game supports Facebook Canvas, you can use the /me/invitable_friends endpoint in order to render a custom invite dialog, then pass the tokens returned by this API to the standard Requests Dialog.

In other cases, apps are no longer able to retrieve the full list of a user's friends (only those friends who have specifically authorized your app using the user_friends permission).

For apps wanting allow people to invite friends to use an app, you can still use the Send Dialog on Web or the new Message Dialog on iOS and Android.

The @RequestBody javadoc states

Annotation indicating a method parameter should be bound to the body of the web request.

It uses registered instances of HttpMessageConverter to deserialize the request body into an object of the annotated parameter type.

And the @RequestParam javadoc states

Annotation which indicates that a method parameter should be bound to a web request parameter.

1. Spring binds the body of the request to the parameter annotated with @RequestBody.

2. Spring binds request parameters from the request body (url-encoded parameters) to your method parameter. Spring will use the name of the parameter, ie. name, to map the parameter.

3. Parameters are resolved in order. The @RequestBody is processed first. Spring will consume all the HttpServletRequest InputStream. When it then tries to resolve the @RequestParam, which is by default required, there is no request parameter in the query string or what remains of the request body, ie. nothing. So it fails with 400 because the request can't be correctly handled by the handler method.

4. The handler for @RequestParam acts first, reading what it can of the HttpServletRequest InputStream to map the request parameter, ie. the whole query string/url-encoded parameters. It does so and gets the value abc mapped to the parameter name. When the handler for @RequestBody runs, there's nothing left in the request body, so the argument used is the empty string.

5. The handler for @RequestBody reads the body and binds it to the parameter. The handler for @RequestParam can then get the request parameter from the URL query string.

6. The handler for @RequestParam reads from both the body and the URL query String. It would usually put them in a Map, but since the parameter is of type String, Spring will serialize the Map as comma separated values. The handler for @RequestBody then, again, has nothing left to read from the body.

Try with this

Response.Clear();
Response.AppendHeader("Content-Type", "application/vnd.openxmlformats-officedocument.presentationml.presentation");
Response.AppendHeader("Content-Disposition", string.Format("attachment;filename={0}.pptx;", getLegalFileName(CurrentPresentation.Presentation_NM)));
Response.Flush();                
Response.BinaryWrite(masterPresentation.ToArray());
Response.End();

Another option is to check if it's busy with a timer:

Set the timer as disabled by default. Then whenever navigating, enable it. i.e.:

WebBrowser1.Navigate("https://www.somesite.com")
tmrBusy.Enabled = True

And the timer:

    Private Sub tmrBusy_Tick(sender As Object, e As EventArgs) Handles tmrBusy.Tick

        If WebBrowser1.IsBusy = True Then

            Debug.WriteLine("WB Busy ...")

        Else

            Debug.WriteLine("WB Done.")
            tmrBusy.Enabled = False

        End If

    End Sub

java.time

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

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

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

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

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

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

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

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

You can do something like this.

 List<Map<String, Object>> mapList = jdbctemplate.queryForList(query));
    return mapList.stream().collect(Collectors.toMap(k -> (Long) k.get("userid"), k -> (String) k.get("username")));

Output:

 {
  1: "abc",
  2: "def",
  3: "ghi"
}

Also, the following piece of code shows how, with a single definition of the function "Animal", it can be a) called directly and b) instantiated by treating it as a constructor function

function Animal(){
    this.abc = 1;
    return 1234; 
}

var x = new Animal();
var y = Animal();

console.log(x); //prints object containing property abc set to value 1
console.log(y); // prints 1234

I just had this problem of Chrome storing a Session ID but I do not like the idea of disabling the option to continue where I left off. I looked at the cookies for the website and found a Session ID cookie for the login page. Deleting that did not correct my problem. I search for the domain and found there was another Session ID cookie on the domain. Deleting both Session ID cookies manually fixed the problem and I did not close and reopen the browser which could have restored the cookies.

Here is a bash script that fully answers the (revised) original question. That is, given any .tsv file, it provides the synopsis for each of the columns in turn. Apart from bash itself, it only uses standard *ix/Mac tools: sed tr wc cut sort uniq.

#!/bin/bash
# Syntax: $0 filename   
# The input is assumed to be a .tsv file

FILE="$1"

cols=$(sed -n 1p $FILE | tr -cd '\t' | wc -c)
cols=$((cols + 2 ))
i=0
for ((i=1; i < $cols; i++))
do
  echo Column $i ::
  cut -f $i < "$FILE" | sort | uniq -c
  echo
done

I recommend using passthru and handling the output buffer directly:

ob_start();
passthru('/usr/bin/python2.7 /srv/http/assets/py/switch.py arg1 arg2');
$output = ob_get_clean(); 

You've started right - now you just need to fill the each student structure in the array:

struct student
{
    public int s_id;
    public String s_name, c_name, dob;
}
class Program
{
    static void Main(string[] args)
    {
        student[] arr = new student[4];

        for(int i = 0; i < 4; i++)
        {
            Console.WriteLine("Please enter StudentId, StudentName, CourseName, Date-Of-Birth");


            arr[i].s_id = Int32.Parse(Console.ReadLine());
            arr[i].s_name = Console.ReadLine();
            arr[i].c_name = Console.ReadLine();
            arr[i].s_dob = Console.ReadLine();
       }
    }
}

Now, just iterate once again and write these information to the console. I will let you do that, and I will let you try to make program to take any number of students, and not just 4.

With Python 2, this doesn't work for non-English words in UTF-8. In this case decode('utf-8') can help:

>>> s='????????'
>>> print s.lower()
????????
>>> print s.decode('utf-8').lower()
????????

There also other ways to use the composer autoload features. Ways that can be useful to load packages without namespaces or packages that come with a custom autoload function.

For example if you want to include a single file that contains an autoload function as well you can use the "files" directive as follows:

"autoload": {
    "psr-0": {
        "": "src/",
        "SymfonyStandard": "app/"
    },
    "files": ["vendor/wordnik/wordnik-php/wordnik/Swagger.php"]
},

And inside the Swagger.php file we got:

function swagger_autoloader($className) {
    $currentDir = dirname(__FILE__);
    if (file_exists($currentDir . '/' . $className . '.php')) {
        include $currentDir . '/' . $className . '.php';
    } elseif (file_exists($currentDir . '/models/' . $className . '.php')) {
        include $currentDir . '/models/' . $className . '.php';
    }
}
spl_autoload_register('swagger_autoloader');

https://getcomposer.org/doc/04-schema.md#files

Otherwise you may want to use a classmap reference:

{
    "autoload": {
        "classmap": ["src/", "lib/", "Something.php"]
    }
}

https://getcomposer.org/doc/04-schema.md#classmap

Note: during your tests remember to launch the composer dump-autoload command or you won't see any change!

./composer.phar dump-autoload

Happy autoloading =)

If you are using JavaScript to render then use escape_JavaScript("<%=render partial: partial_name, locals=>{@newval=>@oldval}%>");

We can improve on Mr Assad's code (the current accepted answer) just a little bit by instantiating only the frame we actually need rather than the entire stack:

new StackFrame(1).GetMethod().Name;

This might perform a little better, though in all likelihood it still has to use the full stack to create that single frame. Also, it still has the same caveats that Alex Lyman pointed out (optimizer/native code might corrupt the results). Finally, you might want to check to be sure that new StackFrame(1) or .GetFrame(1) don't return null, as unlikely as that possibility might seem.

See this related question: Can you use reflection to find the name of the currently executing method?

One thing you may be able to do is get the address of the dynamic named range, and use that as the input in your SQL string. Something like:

Sheets("shtName").range("namedRangeName").Address

Which will spit out an address string, something like $A$1:$A$8

Edit:

As I said in my comment below, you can dynamically get the full address (including sheet name) and either use it directly or parse the sheet name for later use:

ActiveWorkbook.Names.Item("namedRangeName").RefersToLocal

Which results in a string like =Sheet1!$C$1:$C$4. So for your code example above, your SQL statement could be

strRangeAddress = Mid(ActiveWorkbook.Names.Item("namedRangeName").RefersToLocal,2)

strSQL = "SELECT * FROM [strRangeAddress]"

Without quotes works for me:

<item name="android:textStyle">bold|italic</item>

"\n" = new line
'\n' = \n
"\t" = tab
'\t' = \t

Vim has three modes of operation: Input mode, Command mode & Ex mode.

Input mode - everything that you type, all keystrokes are echoed on the screen.

Command mode or Escape mode - everything that you type in this mode is interpreted as a command.

Ex mode - this is another editor, ex. It is a line editor. It works per line or based on a range of lines. In this mode, a : appears at the bottom of the screen. This is the ex editor.

In order to exit Vim, you can exit while you are in either the ex mode or in the command mode. You cannot exit Vim when you are in input mode.

Exiting from ex mode

1. You need to be sure that you are in the Command mode. To do that, simply press the Esc key.

2. Go to the ex mode by pressing the : key

3. Use any of the following combinations in ex mode to exit:

   :q - quit :q! - quit without saving :wq - save & quit or write & quit :wq! - same as wq, but force write in case file permissions are readonly :x - write & quit :qa - quit all. useful when multiple files are opened like: vim abc.txt xyz.txt

Exiting from command mode

1. Press the escape key. You probably have done this already if you are in command mode.

2. Press capital ZZ (shift zz) - save & exit

3. Press capital ZQ (shift zq) - exit without saving.

Below are two methods that are superior to looping. Both handle a "no-find" case.

1. The VBA equivalent of a normal function VLOOKUP with error-handling if the variable doesn't exist (INDEX/MATCH may be a better route than VLOOKUP, ie if your two columns A and B were in reverse order, or were far apart)

2. VBAs FIND method (matching a whole string in column A given I use the xlWhole argument)

   Sub Method1()
   Dim strSearch As String
   Dim strOut As String
   Dim bFailed As Boolean
   
   strSearch = "trees"
   
   On Error Resume Next
   strOut = Application.WorksheetFunction.VLookup(strSearch, Range("A:B"), 2, False)
   If Err.Number <> 0 Then bFailed = True
   On Error GoTo 0
   
   If Not bFailed Then
   MsgBox "corresponding value is " & vbNewLine & strOut
   Else
   MsgBox strSearch & " not found"
   End If
   End Sub
   
   Sub Method2()
       Dim rng1 As Range
       Dim strSearch As String
       strSearch = "trees"
       Set rng1 = Range("A:A").Find(strSearch, , xlValues, xlWhole)
       If Not rng1 Is Nothing Then
           MsgBox "Find has matched " & strSearch & vbNewLine & "corresponding cell is " & rng1.Offset(0, 1)
       Else
           MsgBox strSearch & " not found"
       End If
   End Sub
   

It didn't work for me after Enable Incremental Linking -> "No (/INCREMENTAL:NO)", but it works for me after I deleted the rc file.

If you want to stash only some of changed files, simply just Add other files in the Stage, Then execute git stash save --keep-index

It will stash all unstaged changed files

Supposing you use sql server:

WHERE StartTime BETWEEN DATEADD(HOUR, -1, GetDate())
                    AND DATEADD(HOUR, 1, GetDate())

I see all the answer are ugly and not very clean.

I suggest you use a little bit of recursion to solve your problem. This post is very old, but it might be helpful to future coders.

public static void recursion(int number) {
    if(number > 0) {
        recursion(number/10);
        System.out.printf("%d   ", (number%10));
    }
}

Output:

Input: 12345

Output: 1   2   3   4   5 

If you're on Android, you can do this:

Uri uri = Uri.parse(url);
String v = uri.getQueryParameter("v");

Another example is, you have class like :

@obc class Album: NSObject {
    let name:String
    let singer:Singer
    let artwork:URL
    let playingSong:Song


    // ...

    class func getCurrentlyPlayingSongLyric(duration: Int = 0) -> String {
        // ...
       return playingSong.lyric
    }
}

you will also get the same type of error like :

instance member x cannot be used on type x. 

It's because you assign your method with "class" keyword (which makes your method a type method) and using like :

Album.getCurrentlyPlayingSongLyric(duration: 5)

but who set the playingSong variable before? Ok. You shouldn't use class keyword for that case :

 // ...

 func getCurrentlyPlayingSongLyric(duration: Int = 0) -> String {
        // ...
       return playingSong.lyric
 }

 // ...

Now you're free to go.

$string = 'this is my world, not my world';
$find = 'world';
$replace = 'farm';
$result = preg_replace(strrev("/$find/"),strrev($replace),strrev($string),1);
echo strrev($result); //output: this is my world, not my farm

this should work (not tested!)

var url = window.location.href;    
if (url.indexOf('?') > -1){
   url += '&param=1'
}else{
   url += '?param=1'
}
window.location.href = url;

To expand on this (even though it is an older question); It is not not about the MySQL space itself probably, but about space in general, assuming for tmp files or something like that. My mysql data dir was not full, the / (root) partition was

It's called a "finalizer", and you should usually only create one for a class whose state (i.e.: fields) include unmanaged resources (i.e.: pointers to handles retrieved via p/invoke calls). However, in .NET 2.0 and later, there's actually a better way to deal with clean-up of unmanaged resources: SafeHandle. Given this, you should pretty much never need to write a finalizer again.

var result = nullableproperty ?? defaultvalue;

The ?? (null-coalescing operator) means if the first argument is null, return the second one instead.

If there is nothing to lose you could also just delete your fork just go to settings... go to danger zone section below and click delete repository. It will ask you to input the repository name and your password after. After that you just fork the original again.

I believe this is controlled by the css color property applied to the element.

As far as I know there's no way to do a blanket delete of any cookie set on the domain. You can clear a cookie if you know the name and if the script is on the same domain as the cookie.

You can set the value to empty and the expiration date to somewhere in the past:

var mydate = new Date();
mydate.setTime(mydate.getTime() - 1);
document.cookie = "username=; expires=" + mydate.toGMTString(); 

There's an excellent article here on manipulating cookies using javascript.

In case you are interested in the memory allocation, you may compare each approach using something like this jsfiddle in conjunction with chrome dev tools' timeline tab. You will want to use the trash bin icon at the bottom to force a garbage collection after 'clearing' the array. This should give you a more definite answer for the browser of your choice. A lot of answers here are old and I wouldn't rely on them but rather test as in @tanguy_k's answer above.

(for an intro to the aforementioned tab you can check out here)

Stackoverflow forces me to copy the jsfiddle so here it is:

<html>
<script>
var size = 1000*100
window.onload = function() {
  document.getElementById("quantifier").value = size
}

function scaffold()
{
  console.log("processing Scaffold...");
  a = new Array
}
function start()
{
  size = document.getElementById("quantifier").value
  console.log("Starting... quantifier is " + size);
  console.log("starting test")
  for (i=0; i<size; i++){
    a[i]="something"
  }
  console.log("done...")
}

function tearDown()
{
  console.log("processing teardown");
  a.length=0
}

</script>
<body>
    <span style="color:green;">Quantifier:</span>
    <input id="quantifier" style="color:green;" type="text"></input>
    <button onclick="scaffold()">Scaffold</button>
    <button onclick="start()">Start</button>
    <button onclick="tearDown()">Clean</button>
    <br/>
</body>
</html>

And you should take note that it may depend on the type of the array elements, as javascript manages strings differently than other primitive types, not to mention arrays of objects. The type may affect what happens.

for large numbers that display with scientific notation set format to just '#'

if not exists (select dist_id from tbl_stock where dist_id= @cust_id and item_id=@item_id)
    insert into tbl_stock(dist_id,item_id,qty)values(@cust_id, @item_id, @qty); 
else
    update tbl_stock set qty=(qty + @qty) where dist_id= @cust_id and item_id= @item_id;

Every programming language has its own set of rules and conventions for the kinds of names that you're allowed to use, and the Java programming language is no different. The rules and conventions for naming your variables can be summarized as follows:

• Variable names are case-sensitive. A variable's name can be any legal identifier — an unlimited-length sequence of Unicode letters and digits, beginning with a letter, the dollar sign "$", or the underscore character "_". The convention, however, is to always begin your variable names with a letter, not "$" or "_". Additionally, the dollar sign character, by convention, is never used at all. You may find some situations where auto-generated names will contain the dollar sign, but your variable names should always avoid using it. A similar convention exists for the underscore character; while it's technically legal to begin your variable's name with "_", this practice is discouraged. White space is not permitted.

• Subsequent characters may be letters, digits, dollar signs, or underscore characters. Conventions (and common sense) apply to this rule as well. When choosing a name for your variables, use full words instead of cryptic abbreviations. Doing so will make your code easier to read and understand. In many cases it will also make your code self-documenting; fields named cadence, speed, and gear, for example, are much more intuitive than abbreviated versions, such as s, c, and g. Also keep in mind that the name you choose must not be a keyword or reserved word.

• If the name you choose consists of only one word, spell that word in all lowercase letters. If it consists of more than one word, capitalize the first letter of each subsequent word. The names gearRatio and currentGear are prime examples of this convention. If your variable stores a constant value, such as static final int NUM_GEARS = 6, the convention changes slightly, capitalizing every letter and separating subsequent words with the underscore character. By convention, the underscore character is never used elsewhere.

From the official Java Tutorial.

I hope to provide more background knowledge here.

First, constructor signature of the of method threading::Thread:

class threading.Thread(group=None, target=None, name=None, args=(), kwargs={}, *, daemon=None)

args is the argument tuple for the target invocation. Defaults to ().

Second, A quirk in Python about tuple:

Empty tuples are constructed by an empty pair of parentheses; a tuple with one item is constructed by following a value with a comma (it is not sufficient to enclose a single value in parentheses).

On the other hand, a string is a sequence of characters, like 'abc'[1] == 'b'. So if send a string to args, even in parentheses (still a sting), each character will be treated as a single parameter.

However, Python is so integrated and is not like JavaScript where extra arguments can be tolerated. Instead, it throws an TypeError to complain.

On Chrome 16, and possibly earlier versions, you can use "\n". As a sidenote, "\t" also works

You can get height of the content inside UIScrollView by calculate which child "reaches furthers". To calculate this you have to take in consideration origin Y (start) and item height.

float maxHeight = 0;
for (UIView *child in scrollView.subviews) {
    float childHeight = child.frame.origin.y + child.frame.size.height;
    //if child spans more than current maxHeight then make it a new maxHeight
    if (childHeight > maxHeight)
        maxHeight = childHeight;
}
//set content size
[scrollView setContentSize:(CGSizeMake(320, maxHeight))];

By doing things this way items (subviews) don't have to be stacked directly one under another.

As @Antonijn stated, you need to execute getTitle method, by adding parentheses:

 string t = obj.getTitle();

But I want to add, that you are doing Java programming in C#. There is concept of properties (pair of get and set methods), which should be used in such cases:

public class Pin
{
    private string _title;

    // you don't need to define empty constructor
    // public Pin() { }

    public string Title 
    {
        get { return _title; }
        set { _title = value; }
    }  
}

And even more, in this case you can ask compiler not only for get and set methods generation, but also for back storage generation, via auto-impelemented property usage:

public class Pin
{
    public string Title { get; set; }
}

And now you don't need to execute method, because properties used like fields:

foreach (Pin obj in ClassListPin.pins)
{
     string t = obj.Title;
}

The answers are working fine with xls format but, in my case, it didn't work for xlsx format. Thus I added some code here. it works both xls and xlsx format.

I took the sample from the official sample link.

Hope it may help !

function fileReader(oEvent) {
        var oFile = oEvent.target.files[0];
        var sFilename = oFile.name;

        var reader = new FileReader();
        var result = {};

        reader.onload = function (e) {
            var data = e.target.result;
            data = new Uint8Array(data);
            var workbook = XLSX.read(data, {type: 'array'});
            console.log(workbook);
            var result = {};
            workbook.SheetNames.forEach(function (sheetName) {
                var roa = XLSX.utils.sheet_to_json(workbook.Sheets[sheetName], {header: 1});
                if (roa.length) result[sheetName] = roa;
            });
            // see the result, caution: it works after reader event is done.
            console.log(result);
        };
        reader.readAsArrayBuffer(oFile);
}

// Add your id of "File Input" 
$('#fileUpload').change(function(ev) {
        // Do something 
        fileReader(ev);
}

A very simple way to achieve this is using a formControl with a default value, inside a FormGroup (optional) for example. This is an example using an unit selector to an area input:

ts

H_AREA_UNIT = 1;
M_AREA_UNIT = 2;

exampleForm: FormGroup;

this.exampleForm = this.formBuilder.group({
  areaUnit: [this.H_AREA_UNIT],
});

html

<form [formGroup]="exampleForm">
 <mat-form-field>
   <mat-label>Unit</mat-label>
   <mat-select formControlName="areaUnit">
     <mat-option [value]="H_AREA_UNIT">h</mat-option>
     <mat-option [value]="M_AREA_UNIT">m</mat-option>
   </mat-select>
 </mat-form-field>
</form>

look at this

After working all day on this, I finally found a solution. Here's how I send from Windows XP with WAMP.

1. Use Google's SMTP server. You probably need an account.
2. Download and install Fake Sendmail. I just downloaded it, unzipped it and put it in the WAMP folder.
3. Create a test PHP file. See below.

<?php
    $message = "test message body";
    $result = mail('[email protected]', 'message subject', $message);
    echo "result: $result";
?>

4. Update your php.ini file and your sendmail.ini file (sendmail.ini is in the sendmail folder).
5. Check the error.log file in the sendmail folder that you just created if it doesn't work.

Reference:

• http://www.joshstauffer.com/send-test-emails-with-wampserver/

From here:

"You can also refer to the properties of the data object via that object, instead of accessing them as variables." Meaning that for OP's case this will work (with a significantly smaller change than other possible solutions):

<% if (obj.date) { %><span class="date"><%= date %></span><% }  %>

You can try this:

: ${depth?"Error Message"} ## when your depth variable is not even declared or is unset.

NOTE: Here it's just ? after depth.

or

: ${depth:?"Error Message"} ## when your depth variable is declared but is null like: "depth=". 

NOTE: Here it's :? after depth.

Here if the variable depth is found null it will print the error message and then exit.

the solution here worked for me : https://community.hortonworks.com/articles/4427/fix-under-replicated-blocks-in-hdfs-manually.html

su - <$hdfs_user>

bash-4.1$ hdfs fsck / | grep 'Under replicated' | awk -F':' '{print $1}' >> /tmp/under_replicated_files 

-bash-4.1$ for hdfsfile in `cat /tmp/under_replicated_files`; do echo "Fixing $hdfsfile :" ;  hadoop fs -setrep 3 $hdfsfile; done

To print the second line:

awk 'FNR == 2 {print}'

To print the second field:

awk '{print $2}'

To print the third field of the fifth line:

awk 'FNR == 5 {print $3}'

Here's an example with a header line and (redundant) field descriptions:

awk 'BEGIN {print "Name\t\tAge"}  FNR == 5 {print "Name: "$3"\tAge: "$2}'

There are better ways to align columns than "\t\t" by the way.

Use exit to stop as soon as you've printed the desired record if there's no reason to process the whole file:

awk 'FNR == 2 {print; exit}'

It's not possible to identify the computers accessing a web site without the cooperation of their owners. If they let you, however, you can store a cookie to identify the machine when it visits your site again. The key is, the visitor is in control; they can remove the cookie and appear as a new visitor any time they wish.

There seems to be some debate whether using StringBuilder is still needed with current compilers. So I thought I'll give my 2 cents of experience.

I have a JDBC result set of 10k records (yes, I need all of them in one batch.) Using the + operator takes about 5 minutes on my machine with Java 1.8. Using stringBuilder.append("") takes less than a second for the same query.

So the difference is huge. Inside a loop StringBuilder is much faster.

If you don't mind using a third-party library, with cyclops-react you can mix sequential and parallel Streams within the same pipeline and provide custom ForkJoinPools. For example

 ReactiveSeq.range(1, 1_000_000)
            .foldParallel(new ForkJoinPool(10),
                          s->s.filter(i->true)
                              .peek(i->System.out.println("Thread " + Thread.currentThread().getId()))
                              .max(Comparator.naturalOrder()));

Or if we wished to continue processing within a sequential Stream

 ReactiveSeq.range(1, 1_000_000)
            .parallel(new ForkJoinPool(10),
                      s->s.filter(i->true)
                          .peek(i->System.out.println("Thread " + Thread.currentThread().getId())))
            .map(this::processSequentially)
            .forEach(System.out::println);

Use the sorted function, which sorts the iterable passed in.

The .keys() method returns the keys in an arbitrary order.

Just a tip. Works on firefox only

Element.scrollIntoView();

These are timeout values enforced by JVM for TCP connection establishment and waiting on reading data from socket.

If the value is set to infinity, you will not wait forever. It simply means JVM doesn't have timeout and OS will be responsible for all the timeouts. However, the timeouts on OS may be really long. On some slow network, I've seen timeouts as long as 6 minutes.

Even if you set the timeout value for socket, it may not work if the timeout happens in the native code. We can reproduce the problem on Linux by connecting to a host blocked by firewall or unplugging the cable on switch.

The only safe approach to handle TCP timeout is to run the connection code in a different thread and interrupt the thread when it takes too long.

Check Managing Exceptions with the Debugger page, it explains how to set this up.

Essentially, here are the steps (during debugging):

1. On the Debug menu, click Exceptions.

2. In the Exceptions dialog box, select Thrown for an entire category of exceptions, for example, Common Language Runtime Exceptions.

   -or-

   Expand the node for a category of exceptions, for example, Common Language Runtime Exceptions, and select Thrown for a specific exception within that category.

The simplest way I manage to solve the issue was is by using a ZStack + .edgesIgnoringSafeArea(.all)

struct TestView : View {

    var body: some View {
        ZStack() {
            Color.yellow.edgesIgnoringSafeArea(.all)
            VStack {
                Text("Hello World")
            }
        }
    }
}

According to nginx documentation

there is no syntax for NOT matching a regular expression. Instead, match the target regular expression and assign an empty block, then use location / to match anything else

So you could define something like

location ~ (dir1|file2\.php) { 
    # empty
}

location / {
    rewrite ^/(.*) http://example.com/$1 permanent; 
}

I had this issue once. It turned out to be database query issue. After re-create tables and index it has been fixed.

Although it says proxy error, when you look at server log, it shows execute query timeout. This is what I had before and how I solved it.

Use jQuery

html

<div id="b">&nbsp;</div>

css

div#b {
    position: fixed;
    top:40px;
    left:0;
    width: 40px;
    height: 40px;
    background: url(http://www.wiredforwords.com/IMAGES/FlyingBee.gif) 0 0 no-repeat;

you need to have mysql connector jar in your classpath.

in Java JDBC API makes everything with databases. using JDBC we can write Java applications to
1. Send queries or update SQL to DB(any relational Database) 2. Retrieve and process the results from DB

with below three steps we can able to retrieve data from any Database

Connection con = DriverManager.getConnection(
                     "jdbc:myDriver:DatabaseName",
                     dBuserName,
                     dBuserPassword);

Statement stmt = con.createStatement();
ResultSet rs = stmt.executeQuery("SELECT a, b, c FROM Table");

while (rs.next()) {
    int x = rs.getInt("a");
    String s = rs.getString("b");
    float f = rs.getFloat("c");
}

According to Google Developers article, you can:

• Use asynchronous script loading, using <script src="..." async> or element.appendChild(),
• Submit the script provider to Google for whitelisting.

You don't. Your array doesn't have a key [1]. You could:

• Make a new array, which contains the keys:

  $newArray = array_keys($array);
  echo $newArray[0];
  

  But the value "one" is at $newArray[0], not [1].
  A shortcut would be:

  echo current(array_keys($array));
  

• Get the first key of the array:

   reset($array);
   echo key($array);
  

• Get the key corresponding to the value "value":

  echo array_search('value', $array);
  

This all depends on what it is exactly you want to do. The fact is, [1] doesn't correspond to "one" any which way you turn it.

If you want to take advantage of the 60FPS smoothness that the "transform" property offers, you can combine the two:

@keyframes changewidth {
  from {
    transform: scaleX(1);
  }

  to {
    transform: scaleX(2);
  }
}

div {
  animation-duration: 0.1s;
  animation-name: changewidth;
  animation-iteration-count: infinite;
  animation-direction: alternate;
}

More explanation on why transform offers smoother transitions here: https://medium.com/outsystems-experts/how-to-achieve-60-fps-animations-with-css3-db7b98610108

To anyone who came across this question who are using SQL Server Database and still having an exception thrown even after adding the following annotation on the int primary key

[Key]
[DatabaseGenerated(DatabaseGeneratedOption.Identity)]
public int Id { get; set; }

Please check your SQL, make sure your the primary key has 'IDENTITY(startValue, increment)' next to it,

CREATE TABLE [dbo].[User]
(
    [Id] INT IDENTITY(1,1) NOT NULL PRIMARY KEY
)

This will make the database increments the id every time a new row is added, with a starting value of 1 and increments of 1.

I accidentally overlooked that in my SQL which cost me an hour of my life, so hopefully this helps someone!!!

Both these will give you the first child node:

console.log(parentElement.firstChild); // or
console.log(parentElement.childNodes[0]);

If you need the first child that is an element node then use:

console.log(parentElement.children[0]);

Edit

Ah, I see your problem now; parentElement is an array.

If you know that getElementsByClassName will only return one result, which it seems you do, you should use [0] to dearray (yes, I made that word up) the element:

var parentElement = document.getElementsByClassName("uniqueClassName")[0];

Try this out.

int day = 0;
        int hh = 0;
        int mm = 0;
        try {
            SimpleDateFormat dateFormat = new SimpleDateFormat("dd-MMM-yyyy 'at' hh:mm aa");
            Date oldDate = dateFormat.parse(oldTime);
            Date cDate = new Date();
            Long timeDiff = cDate.getTime() - oldDate.getTime();
            day = (int) TimeUnit.MILLISECONDS.toDays(timeDiff);
            hh = (int) (TimeUnit.MILLISECONDS.toHours(timeDiff) - TimeUnit.DAYS.toHours(day));
            mm = (int) (TimeUnit.MILLISECONDS.toMinutes(timeDiff) - TimeUnit.HOURS.toMinutes(TimeUnit.MILLISECONDS.toHours(timeDiff)));



        } catch (ParseException e) {
            e.printStackTrace();
        }

        if (mm <= 60 && hh!= 0) {
            if (hh <= 60 && day != 0) {
                return day + " DAYS AGO";
            } else {
                return hh + " HOUR AGO";
            }
        } else {
            return mm + " MIN AGO";
        }

Choose one you need:

>>> s = "Rajasekar SP  def"
>>> s.split(' ')
['Rajasekar', 'SP', '', 'def']
>>> s.split()
['Rajasekar', 'SP', 'def']
>>> s.partition(' ')
('Rajasekar', ' ', 'SP  def')

str.split and str.partition

I think the fastest and simplest way would be to use an XmlReader, this will not require any recursion and minimal memory foot print.

Here is a simple example, for compactness I just used a simple string of course you can use a stream from a file etc.

  string xml = @"
    <parent>
      <child>
        <nested />
      </child>
      <child>
        <other>
        </other>
      </child>
    </parent>
    ";

  XmlReader rdr = XmlReader.Create(new System.IO.StringReader(xml));
  while (rdr.Read())
  {
    if (rdr.NodeType == XmlNodeType.Element)
    {
      Console.WriteLine(rdr.LocalName);
    }
  }

The result of the above will be

parent
child
nested
child
other

A list of all the elements in the XML document.

I think what you want is to set the android:layout_weight,

http://developer.android.com/resources/tutorials/views/hello-linearlayout.html

something like this (I'm just putting text views above and below as placeholders):

  <LinearLayout

This answer will demonstrate the difference between implementation, api, and compile on a project.

Let's say I have a project with three Gradle modules:

• app (an Android application)
• myandroidlibrary (an Android library)
• myjavalibrary (a Java library)

app has myandroidlibrary as dependencies. myandroidlibrary has myjavalibrary as dependencies.

myjavalibrary has a MySecret class

public class MySecret {

    public static String getSecret() {
        return "Money";
    }
}

myandroidlibrary has MyAndroidComponent class that manipulate value from MySecret class.

public class MyAndroidComponent {

    private static String component = MySecret.getSecret();

    public static String getComponent() {
        return "My component: " + component;
    }    
}

Lastly, app is only interested in the value from myandroidlibrary

TextView tvHelloWorld = findViewById(R.id.tv_hello_world);
tvHelloWorld.setText(MyAndroidComponent.getComponent());

Now, let's talk about dependencies...

app need to consume :myandroidlibrary, so in app build.gradle use implementation.

(Note: You can use api/compile too. But hold that thought for a moment.)

dependencies {
    implementation project(':myandroidlibrary')      
}

What do you think myandroidlibrary build.gradle should look like? Which scope we should use?

We have three options:

dependencies {
    // Option #1
    implementation project(':myjavalibrary') 
    // Option #2
    compile project(':myjavalibrary')      
    // Option #3
    api project(':myjavalibrary')           
}

What's the difference between them and what should I be using?

Compile or Api (option #2 or #3)

If you're using compile or api. Our Android Application now able to access myandroidcomponent dependency, which is a MySecret class.

TextView textView = findViewById(R.id.text_view);
textView.setText(MyAndroidComponent.getComponent());
// You can access MySecret
textView.setText(MySecret.getSecret());

Implementation (option #1)

If you're using implementation configuration, MySecret is not exposed.

TextView textView = findViewById(R.id.text_view);
textView.setText(MyAndroidComponent.getComponent());
// You can NOT access MySecret
textView.setText(MySecret.getSecret()); // Won't even compile

So, which configuration you should choose? That really depends on your requirement.

If you want to expose dependencies use api or compile.

If you don't want to expose dependencies (hiding your internal module) then use implementation.

Note:

This is just a gist of Gradle configurations, refer to Table 49.1. Java Library plugin - configurations used to declare dependencies for more detailed explanation.

To make my future me happy: RTFM - don't use the gitlab-ci-token at all, but the .netrc file.

There are a couple of important points:

1. echo -e "machine gitlab.com\nlogin gitlab-ci-token\npassword ${CI_JOB_TOKEN}" > ~/.netrc
2. Don't forget to replace "gitlab.com" by your URL!
3. Don't try to be smart and create the .netrc file directly - gitlab will not replace the $CI_JOB_TOKEN within the file!
4. Use https://gitlab.com/whatever/foobar.com - not ssh://git@foobar, not git+ssh://, not git+https://. You also don't need any CI-TOKEN stuff in the URL.
5. Make sure you can git clone [url from step 4]

Background: I got

fatal: could not read Username for 'https://gitlab.mycompany.com': No such device or address

when I tried to make Ansible + Gitlab + Docker work as I imagine it. Now it works.

By the following code you can get the current URL in Jquery.

$(location).attr('hostname');                //origin URL
$(location).attr('pathname');                // path name
$(location).attr('hash');                    // everything comes after hash

It may be achieved in a pretty simple way:

• iterate from 0 to 100 with for loop
• sleep every step for 25ms (0.25 second)
• append to the $bar variable another = sign to make the progress bar wider
• echo progress bar and percentage (\r cleans line and returns to the beginning of the line; -ne makes echo doesn't add newline at the end and parses \r special character)

function progress {
    bar=''
    for (( x=0; x <= 100; x++ )); do
        sleep 0.25
        bar="${bar}="
        echo -ne "$bar ${x}%\r"
    done
    echo -e "\n"
}

$ progress
> ========== 10% # here: after 2.5 seconds

$ progress
> ============================== 30% # here: after 7.5 seconds

COLORED PROGRESS BAR

function progress {
    bar=''
    for (( x=0; x <= 100; x++ )); do
        sleep 0.05
        bar="${bar} "

        echo -ne "\r"
        echo -ne "\e[43m$bar\e[0m"

        local left="$(( 100 - $x ))"
        printf " %${left}s"
        echo -n "${x}%"
    done
    echo -e "\n"
}

To make a progress bar colorful, you can use formatting escape sequence - here the progress bar is yellow: \e[43m, then we reset custom settings with \e[0m, otherwise it would affect further input even when the progress bar is done.

If a DateTime solution is acceptable this snippet returns the year of last month and month of last month avoiding the possible trap when you run this in January.

function fn_LastMonthYearNumber()
{
 $now = new DateTime();
 $lastMonth = $now->sub(new DateInterval('P1M'));
 $lm= $lastMonth->format('m');
 $ly= $lastMonth->format('Y');
 return array($lm,$ly);
}

You can use it without casting such as:

select sum(`stuff`) as mySum from test;

Or cast it to decimal:

select sum(cast(`stuff` as decimal(4,2))) as mySum from test;

SQLFiddle

EDIT

For SQL Server, you can use:

select sum(cast(stuff as decimal(5,2))) as mySum from test;

SQLFiddle

f=open(file,"r")
lines=f.readlines()
result=[]
for x in lines:
    result.append(x.split(' ')[1])
f.close()

You can do the same using a list comprehension

print([x.split(' ')[1] for x in open(file).readlines()])

Docs on split()

string.split(s[, sep[, maxsplit]])

Return a list of the words of the string s. If the optional second argument sep is absent or None, the words are separated by arbitrary strings of whitespace characters (space, tab, newline, return, formfeed). If the second argument sep is present and not None, it specifies a string to be used as the word separator. The returned list will then have one more item than the number of non-overlapping occurrences of the separator in the string.

So, you can omit the space I used and do just x.split() but this will also remove tabs and newlines, be aware of that.

(This is my third answer because I misunderstood what your code was doing in my original, and then made a small but crucial mistake in my second—hopefully three's a charm.

Edits: Since this seems to be a popular answer, I've made a few modifications to improve its implementation over the years—most not too major. This is so if folks use it as template, it will provide an even better basis.

As others have pointed out, your MemoryError problem is most likely because you're attempting to read the entire contents of huge files into memory and then, on top of that, effectively doubling the amount of memory needed by creating a list of lists of the string values from each line.

Python's memory limits are determined by how much physical ram and virtual memory disk space your computer and operating system have available. Even if you don't use it all up and your program "works", using it may be impractical because it takes too long.

Anyway, the most obvious way to avoid that is to process each file a single line at a time, which means you have to do the processing incrementally.

To accomplish this, a list of running totals for each of the fields is kept. When that is finished, the average value of each field can be calculated by dividing the corresponding total value by the count of total lines read. Once that is done, these averages can be printed out and some written to one of the output files. I've also made a conscious effort to use very descriptive variable names to try to make it understandable.

try:
    from itertools import izip_longest
except ImportError:    # Python 3
    from itertools import zip_longest as izip_longest

GROUP_SIZE = 4
input_file_names = ["A1_B1_100000.txt", "A2_B2_100000.txt", "A1_B2_100000.txt",
                    "A2_B1_100000.txt"]
file_write = open("average_generations.txt", 'w')
mutation_average = open("mutation_average", 'w')  # left in, but nothing written

for file_name in input_file_names:
    with open(file_name, 'r') as input_file:
        print('processing file: {}'.format(file_name))

        totals = []
        for count, fields in enumerate((line.split('\t') for line in input_file), 1):
            totals = [sum(values) for values in
                        izip_longest(totals, map(float, fields), fillvalue=0)]
        averages = [total/count for total in totals]

        for print_counter, average in enumerate(averages):
            print('  {:9.4f}'.format(average))
            if print_counter % GROUP_SIZE == 0:
                file_write.write(str(average)+'\n')

file_write.write('\n')
file_write.close()
mutation_average.close()

Just treat the ES6 class name the same as you would have treated the constructor name in the ES5 way. They are one and the same.

The ES6 syntax is just syntactic sugar and creates exactly the same underlying prototype, constructor function and objects.

So, in your ES6 example with:

// animal.js
class Animal {
    ...
}

var a = new Animal();

module.exports = {Animal: Animal};

You can just treat Animal like the constructor of your object (the same as you would have done in ES5). You can export the constructor. You can call the constructor with new Animal(). Everything is the same for using it. Only the declaration syntax is different. There's even still an Animal.prototype that has all your methods on it. The ES6 way really does create the same coding result, just with fancier/nicer syntax.

On the import side, this would then be used like this:

const Animal = require('./animal.js').Animal;

let a = new Animal();

This scheme exports the Animal constructor as the .Animal property which allows you to export more than one thing from that module.

If you don't need to export more than one thing, you can do this:

// animal.js
class Animal {
    ...
}

module.exports = Animal;

And, then import it with:

const Animal = require('./animal.js');

let a = new Animal();

Previous answers can be improved in terms of performances and compatibility.

Check once if the Error object exists, if not declare it :

if (typeof Error === "undefined") {
    Error = function(message) {
        this.message = message;
    };
    Error.prototype.message = "";
}

Then, each assertion will check the condition, and always throw an Error object

function assert(condition, message) {
    if (!condition) throw new Error(message || "Assertion failed");
}

Keep in mind that the console will not display the real error line number, but the line of the assert function, which is not useful for debugging.

You can also check if your version is using MKL with:

import numpy
numpy.show_config()

You can simply add DISTINCT in front.

SELECT GROUP_CONCAT(DISTINCT categories SEPARATOR ' ')

if you want to sort,

SELECT GROUP_CONCAT(DISTINCT categories ORDER BY categories ASC SEPARATOR ' ')

string::c.str() returns a string of type const char * as seen here

A quick fix: try casting printfunc(num,addr,(char *)data.str().c_str());

While the above may work, it is undefined behaviour, and unsafe.

Here's a nicer solution using templates:

char * my_argument = const_cast<char*> ( ...c_str() );

For the original question based on Bootstrap 3, the solution was to use push-pull.

In Bootstrap 4 it's now possible to change the order, even when the columns are full-width stacked vertically, thanks to Bootstrap 4 flexbox. OFC, the push pull method will still work, but now there are other ways to change column order in Bootstrap 4, making it possible to re-order full-width columns.

Method 1 - Use flex-column-reverse for xs screens:

<div class="row flex-column-reverse flex-md-row">
    <div class="col-md-3">
        sidebar
    </div>
    <div class="col-md-9">
        main
    </div>
</div>

Method 2 - Use order-first for xs screens:

<div class="row">
    <div class="col-md-3">
        sidebar
    </div>
    <div class="col-md-9 order-first order-md-last">
        main
    </div>
</div>

Bootstrap 4.1: https://www.codeply.com/go/e0v77yGtcr

Original 3.x Answer

For the original question based on Bootstrap 3, the solution was to use push-pull for the larger widths, and then the columns will show is their natural order on smaller (xs) widths. (A-B reverse to B-A).

<div class="container">
    <div class="row">
        <div class="col-md-9 col-md-push-3">
            main
        </div>
        <div class="col-md-3 col-md-pull-9">
            sidebar
        </div>
    </div>
</div>

Bootstrap 3: http://www.codeply.com/go/wgzJXs3gel

@emre stated, "You cannot change the order of columns in smaller screens but you can do that in large screens". However, this should be clarified to state: "You cannot change the order of full-width "stacked" columns.." in Bootstrap 3.

You can have fileZilla and use FTP Account to update plugins and themes. Or you can just login to Cpanel and access wordpress folder and then you can update theme by unzipping theme or plugin.

Dude... exit() function is defined under stdlib.h

So you need to add a preprocessor.

Put include stdlib.h in the header section

Then use exit(); wherever you like but remember to put an interger number in the parenthesis of exit.

for example:

exit(0);

We could do it with jQuery:

$(window).resize(function(){
    alert(window.innerWidth);

    $scope.$apply(function(){
       //do something to update current scope based on the new innerWidth and let angular update the view.
    });
});

Be aware that when you bind an event handler inside scopes that could be recreated (like ng-repeat scopes, directive scopes,..), you should unbind your event handler when the scope is destroyed. If you don't do this, everytime when the scope is recreated (the controller is rerun), there will be 1 more handler added causing unexpected behavior and leaking.

In this case, you may need to identify your attached handler:

  $(window).on("resize.doResize", function (){
      alert(window.innerWidth);

      $scope.$apply(function(){
          //do something to update current scope based on the new innerWidth and let angular update the view.
      });
  });

  $scope.$on("$destroy",function (){
      $(window).off("resize.doResize"); //remove the handler added earlier
  });

In this example, I'm using event namespace from jQuery. You could do it differently according to your requirements.

Improvement: If your event handler takes a bit long time to process, to avoid the problem that the user may keep resizing the window, causing the event handlers to be run many times, we could consider throttling the function. If you use underscore, you can try:

$(window).on("resize.doResize", _.throttle(function (){
    alert(window.innerWidth);

    $scope.$apply(function(){
        //do something to update current scope based on the new innerWidth and let angular update the view.
    });
},100));

or debouncing the function:

$(window).on("resize.doResize", _.debounce(function (){
     alert(window.innerWidth);

     $scope.$apply(function(){
         //do something to update current scope based on the new innerWidth and let angular update the view.
     });
},100));

Difference Between throttling and debouncing a function

Even without seeing your JSON string you can tell from the error message that it is not the correct structure to be parsed into an instance of your class.

Gson is expecting your JSON string to begin with an object opening brace. e.g.

{

But the string you have passed to it starts with an open quotes

The other answers demonstrate the difference between array_walk (in-place modification) and array_map (return modified copy) quite well. However, they don't really mention array_reduce, which is an illuminating way to understand array_map and array_filter.

The array_reduce function takes an array, a two-argument function and an 'accumulator', like this:

array_reduce(array('a', 'b', 'c', 'd'),
             'my_function',
             $accumulator)

The array's elements are combined with the accumulator one at a time, using the given function. The result of the above call is the same as doing this:

my_function(
  my_function(
    my_function(
      my_function(
        $accumulator,
        'a'),
      'b'),
    'c'),
  'd')

If you prefer to think in terms of loops, it's like doing the following (I've actually used this as a fallback when array_reduce wasn't available):

function array_reduce($array, $function, $accumulator) {
  foreach ($array as $element) {
    $accumulator = $function($accumulator, $element);
  }
  return $accumulator;
}

This looping version makes it clear why I've called the third argument an 'accumulator': we can use it to accumulate results through each iteration.

So what does this have to do with array_map and array_filter? It turns out that they're both a particular kind of array_reduce. We can implement them like this:

array_map($function, $array)    === array_reduce($array, $MAP,    array())
array_filter($array, $function) === array_reduce($array, $FILTER, array())

Ignore the fact that array_map and array_filter take their arguments in a different order; that's just another quirk of PHP. The important point is that the right-hand-side is identical except for the functions I've called $MAP and $FILTER. So, what do they look like?

$MAP = function($accumulator, $element) {
  $accumulator[] = $function($element);
  return $accumulator;
};

$FILTER = function($accumulator, $element) {
  if ($function($element)) $accumulator[] = $element;
  return $accumulator;
};

As you can see, both functions take in the $accumulator and return it again. There are two differences in these functions:

• $MAP will always append to $accumulator, but $FILTER will only do so if $function($element) is TRUE.
• $FILTER appends the original element, but $MAP appends $function($element).

Note that this is far from useless trivia; we can use it to make our algorithms more efficient!

We can often see code like these two examples:

// Transform the valid inputs
array_map('transform', array_filter($inputs, 'valid'))

// Get all numeric IDs
array_filter(array_map('get_id', $inputs), 'is_numeric')

Using array_map and array_filter instead of loops makes these examples look quite nice. However, it can be very inefficient if $inputs is large, since the first call (map or filter) will traverse $inputs and build an intermediate array. This intermediate array is passed straight into the second call, which will traverse the whole thing again, then the intermediate array will need to be garbage collected.

We can get rid of this intermediate array by exploiting the fact that array_map and array_filter are both examples of array_reduce. By combining them, we only have to traverse $inputs once in each example:

// Transform valid inputs
array_reduce($inputs,
             function($accumulator, $element) {
               if (valid($element)) $accumulator[] = transform($element);
               return $accumulator;
             },
             array())

// Get all numeric IDs
array_reduce($inputs,
             function($accumulator, $element) {
               $id = get_id($element);
               if (is_numeric($id)) $accumulator[] = $id;
               return $accumulator;
             },
             array())

NOTE: My implementations of array_map and array_filter above won't behave exactly like PHP's, since my array_map can only handle one array at a time and my array_filter won't use "empty" as its default $function. Also, neither will preserve keys.

It's not difficult to make them behave like PHP's, but I felt that these complications would make the core idea harder to spot.

Once you are quite good in Java SE (lets say you are able to pass SCJP), I'd suggest you get junior Java programmer job and improve yourself on real world problems

Math.round((new Date().setHours(23) - new Date(new Date().getFullYear(), 0, 1, 0, 0, 0))/1000/86400);

further optimizes the answer.

Moreover, by changing setHours(23) or the last-but-two zero later on to another value may provide day-of-year related to another timezone. For example, to retrieve from Europe a resource located in America.

A simple AJAX call to your server, and then the serverside logic to get the ip address should do the trick.

$.getJSON('getip.php', function(data){
  alert('Your ip is: ' +  data.ip);
});

Then in php you might do:

<?php
/* getip.php */
header('Cache-Control: no-cache, must-revalidate');
header('Expires: Mon, 26 Jul 1997 05:00:00 GMT');
header('Content-type: application/json');

if (!empty($_SERVER['HTTP_CLIENT_IP']))
{
  $ip=$_SERVER['HTTP_CLIENT_IP'];
}
elseif (!empty($_SERVER['HTTP_X_FORWARDED_FOR']))
{
  $ip=$_SERVER['HTTP_X_FORWARDED_FOR'];
}
else
{
  $ip=$_SERVER['REMOTE_ADDR'];
}
print json_encode(array('ip' => $ip));

Here's another integrated method example maybe helpful.

from sklearn.datasets import load_iris
iris_X, iris_y = load_iris(return_X_y=True, as_frame=True)
type(iris_X), type(iris_y)

The data iris_X are imported as pandas DataFrame and the target iris_y are imported as pandas Series.

The problem is that POST method is forbidden for Nginx server's static files requests. Here is the workaround:

# Pass 405 as 200 for requested address:

server {
listen       80;
server_name  localhost;

location / {
    root   html;
    index  index.html index.htm;
}

error_page  404     /404.html;
error_page  403     /403.html;

error_page  405     =200 $uri;
}

If using proxy:

# If Nginx is like proxy for Apache:

error_page 405 =200 @405; 

location @405 { 
    root /htdocs; 
    proxy_pass http://localhost:8080; 
}

If using FastCGI:

location ~\.php(.*) {
fastcgi_pass 127.0.0.1:9000;
fastcgi_split_path_info ^(.+\.php)(.*)$;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_param PATH_INFO $fastcgi_path_info;
fastcgi_param PATH_TRANSLATED $document_root$fastcgi_path_info;
include /etc/nginx/fastcgi_params;
}

Browsers usually use GET, so you can use online tools like ApiTester to test your requests.

Thanks @muhqu for his great answer. In my case not all changes files had permissions changed which prevented the command to work.

$ git diff -p -R --no-ext-diff --no-color | grep -E "^(diff|(old|new) mode)" --color=never
diff --git b/file1 a/file1
diff --git b/file2 a/file2
old mode 100755
new mode 100644
$ git diff -p -R --no-ext-diff --no-color | grep -E "^(diff|(old|new) mode)" --color=never | git apply
warning: file1 has type 100644, expected 100755

The patch would then stop and files would be left untouched.

In case some people have similar problem I solved this by tweaking the command to grep only files with permission changed:

grep -E "^old mode (100644|100755)" -B1 -A1

or for the git alias

git config --global --add alias.permission-reset '!git diff -p -R --no-ext-diff --no-color | grep -E "^old mode (100644|100755)" -B1 -A1 --color=never | git apply'

Use genfromtxt instead. It's a much more general method than loadtxt:

import numpy as np
print np.genfromtxt('col.txt',dtype='str')

Using the file col.txt:

foo bar
cat dog
man wine

This gives:

[['foo' 'bar']
 ['cat' 'dog']
 ['man' 'wine']]

If you expect that each row has the same number of columns, read the first row and set the attribute filling_values to fix any missing rows.

Answer from Chris is not possible because there is no save mail option (at least in version 8.5) in LN

It is possible, File > Save As

You'll need to serialize your object into some kind of string representation. One possible string representation is JSON, and one of the easiest ways to serialize to/from JSON in android, if you ask me, is through Google GSON.

In that case you just put the string return value from (new Gson()).toJson(myObject); and retrieve the string value and use fromJson to turn it back into your object.

If your object isn't very complex, however, it might not be worth the overhead, and you could consider passing the separate values of the object instead.

The basic one, ask tasklist to filter its output and only show the indicated process id information

tasklist /fi "pid eq 4444" 

To only get the process name, the line must be splitted

for /f "delims=," %%a in ('
    tasklist /fi "pid eq 4444" /nh /fo:csv
') do echo %%~a

In this case, the list of processes is retrieved without headers (/nh) in csv format (/fo:csv). The commas are used as token delimiters and the first token in the line is the image name

note: In some windows versions (one of them, my case, is the spanish windows xp version), the pid filter in the tasklist does not work. In this case, the filter over the list of processes must be done out of the command

for /f "delims=," %%a in ('
    tasklist /fo:csv /nh ^| findstr /b /r /c:"[^,]*,\"4444\","
') do echo %%~a

This will generate the task list and filter it searching for the process id in the second column of the csv output.

edited: alternatively, you can suppose what has been made by the team that translated the OS to spanish. I don't know what can happen in other locales.

tasklist /fi "idp eq 4444" 

Edited @ajhuddy's answer a little. Only for bar charts. My version adds:

• Fade in animation for the values.
• Prevent clipping by positioning the value inside the bar if the bar is too high.
• No blinking.

Downside: When hovering over a bar that has value inside it the value might look a little jagged. I have not found a solution do disable hover effects. It might also need tweaking depending on your own settings.

Configuration:

bar: {
  tooltips: {
    enabled: false
  },
  hover: {
    animationDuration: 0
  },
  animation: {
    onComplete: function() {
      this.chart.controller.draw();
      drawValue(this, 1);
    },
    onProgress: function(state) {
      var animation = state.animationObject;
      drawValue(this, animation.currentStep / animation.numSteps);
    }
  }
}

Helpers:

// Font color for values inside the bar
var insideFontColor = '255,255,255';
// Font color for values above the bar
var outsideFontColor = '0,0,0';
// How close to the top edge bar can be before the value is put inside it
var topThreshold = 20;

var modifyCtx = function(ctx) {
  ctx.font = Chart.helpers.fontString(Chart.defaults.global.defaultFontSize, 'normal', Chart.defaults.global.defaultFontFamily);
  ctx.textAlign = 'center';
  ctx.textBaseline = 'bottom';
  return ctx;
};

var fadeIn = function(ctx, obj, x, y, black, step) {
  var ctx = modifyCtx(ctx);
  var alpha = 0;
  ctx.fillStyle = black ? 'rgba(' + outsideFontColor + ',' + step + ')' : 'rgba(' + insideFontColor + ',' + step + ')';
  ctx.fillText(obj, x, y);
};

var drawValue = function(context, step) {
  var ctx = context.chart.ctx;

  context.data.datasets.forEach(function (dataset) {
    for (var i = 0; i < dataset.data.length; i++) {
      var model = dataset._meta[Object.keys(dataset._meta)[0]].data[i]._model;
      var textY = (model.y > topThreshold) ? model.y - 3 : model.y + 20;
      fadeIn(ctx, dataset.data[i], model.x, textY, model.y > topThreshold, step);
    }
  });
};

 BigDecimal obj = new BigDecimal("100");
 if(obj.intValue()>0)
    System.out.println("yes");

Like you said remote_repo_url is indeed the IP of the server, and yes it needs to be added on each PC, but it's easier to understand if you create the server first then ask each to clone it.

There's several ways to connect to the server, you can use ssh, http, or even a network drive, each has it's pros and cons. You can refer to the documentation about protocols and how to connect to the server

You can check the rest of chapter 4 for more detailed information, as it's talking about how to set up your own server

Result has an optional $type parameter which decides what type of result is returned. By default ($type = "object"), it returns an object (result_object()). It can be set to "array", then it will return an array of result, that being equivalent of caling result_array(). The third version accepts a custom class to use as a result object.

The code from CodeIgniter:

/**
* Query result. Acts as a wrapper function for the following functions.
*
* @param string $type 'object', 'array' or a custom class name
* @return array
*/
public function result($type = 'object')
{
    if ($type === 'array')
    {
        return $this->result_array();
    }
    elseif ($type === 'object')
    {
        return $this->result_object();
    }
    else
    {
        return $this->custom_result_object($type);
    }
}

Arrays are technically faster, but they are not objects. It depends where do you want to use the result. Most of the time, arrays are sufficient.

This will let you read, write and create the file if it don't exist:

f = open('filename.txt','a+')
f = open('filename.txt','r+')

Often used commands:

f.readline() #Read next line
f.seek(0) #Jump to beginning
f.read(0) #Read all file
f.write('test text') #Write 'test text' to file
f.close() #Close file

I think it's better to always use ApplicationContext, unless you're in a mobile environment like someone else said already. ApplicationContext has more functionality and you definitely want to use the PostProcessors such as RequiredAnnotationBeanPostProcessor, AutowiredAnnotationBeanPostProcessor and CommonAnnotationBeanPostProcessor, which will help you simplify your Spring configuration files, and you can use annotations such as @Required, @PostConstruct, @Resource, etc in your beans.

Even if you don't use all the stuff ApplicationContext offers, it's better to use it anyway, and then later if you decide to use some resource stuff such as messages or post processors, or the other schema to add transactional advices and such, you will already have an ApplicationContext and won't need to change any code.

If you're writing a standalone app, load the ApplicationContext in your main method, using a ClassPathXmlApplicationContext, and get the main bean and invoke its run() (or whatever method) to start your app. If you're writing a web app, use the ContextLoaderListener in web.xml so that it creates the ApplicationContext and you can later get it from the ServletContext, regardless of whether you're using JSP, JSF, JSTL, struts, Tapestry, etc.

Also, remember you can use multiple Spring configuration files and you can either create the ApplicationContext by listing all the files in the constructor (or listing them in the context-param for the ContextLoaderListener), or you can just load a main config file which has import statements. You can import a Spring configuration file into another Spring configuration file by using <import resource="otherfile.xml" /> which is very useful when you programmatically create the ApplicationContext in the main method and load only one Spring config file.

The solution was to call...

$scope.$apply();

...in my jQuery event callback.

For IPv4, you could get away with storing the 4 raw bytes of the IP address (each of the numbers between the periods in an IP address are 0-255, i.e., one byte). But then you would have to translate going in and out of the DB and that's messy.

IPv6 addresses are 128 bits (as opposed to 32 bits of IPv4 addresses). They are usually written as 8 groups of 4 hex digits separated by colons: 2001:0db8:85a3:0000:0000:8a2e:0370:7334. 39 characters is appropriate to store IPv6 addresses in this format.

Edit: However, there is a caveat, see @Deepak's answer for details about IPv4-mapped IPv6 addresses. (The correct maximum IPv6 string length is 45 characters.)

Checkout gunzip-file

import gunzip from 'gunzip-file';

const unzipAll = async () => {
  try {
    const compFiles = fs.readdirSync('tmp')
    await Promise.all(compFiles.map( async file => {
      if(file.endsWith(".gz")){
        gunzip(`tmp/${file}`, `tmp/${file.slice(0, -3)}`)
      }
    }));
  }
  catch(err) {
    console.log(err)
  }
}

A simple forEach loop solves this quite well:

let text = 'the red apple and the green ball';
const toStrip = ['red', 'green'];
toStrip.forEach(x => {
   text = text.replace(x, '');
});

console.log(text);
// logs -> the apple and the ball

Chrome browser considers integer value as return type not boolean value so,

this.state.data.sort((a, b) => a.item.timeM > b.item.timeM ? 1:-1).map(
    (item, i) => <div key={i}> {item.matchID} {item.timeM} {item.description}</div>
)

itertools.combinations is in general the fastest way to get combinations from a Python container (if you do in fact want combinations, i.e., arrangements WITHOUT repetitions and independent of order; that's not what your code appears to be doing, but I can't tell whether that's because your code is buggy or because you're using the wrong terminology).

If you want something different than combinations perhaps other iterators in itertools, product or permutations, might serve you better. For example, it looks like your code is roughly the same as:

for val in itertools.product(np.arange(0, 1, 0.1), repeat=6):
    print F(val)

All of these iterators yield tuples, not lists or numpy arrays, so if your F is picky about getting specifically a numpy array you'll have to accept the extra overhead of constructing or clearing and re-filling one at each step.

Pure jQuery.

  type: "GET",
  url: "https://example.com/file",
  headers: {
    'Authorization': 'Bearer eyJraWQiFUDA.......TZxX1MGDGyg'

  xhrFields: {
    responseType: 'blob'
  },
  success: function (blob) {
    var windowUrl = window.URL || window.webkitURL;
    var url = windowUrl.createObjectURL(blob);
    var anchor = document.createElement('a');
    anchor.href = url;
    anchor.download = 'filename.zip';
    anchor.click();
    anchor.parentNode.removeChild(anchor);
    windowUrl.revokeObjectURL(url);
  },
  error: function (error) {
    console.log(error);
  }
});

@RequestBody : Annotation indicating a method parameter should be bound to the body of the HTTP request.

For example:

@RequestMapping(path = "/something", method = RequestMethod.PUT)
public void handle(@RequestBody String body, Writer writer) throws IOException {
    writer.write(body);
}

@ResponseBody annotation can be put on a method and indicates that the return type should be written straight to the HTTP response body (and not placed in a Model, or interpreted as a view name).

For example:

@RequestMapping(path = "/something", method = RequestMethod.PUT)
public  @ResponseBody String helloWorld() {
    return "Hello World";
}  

Alternatively, we can use @RestController annotation in place of @Controller annotation. This will remove the need to using @ResponseBody.

You can use an alert dialog

    AlertDialog.Builder b = new Builder(this);
    b.setTitle("Example");
    String[] types = {"By Zip", "By Category"};
    b.setItems(types, new OnClickListener() {

        @Override
        public void onClick(DialogInterface dialog, int which) {

            dialog.dismiss();
            switch(which){
            case 0:
                onZipRequested();
                break;
            case 1:
                onCategoryRequested();
                break;
            }
        }

    });

    b.show();

This will close the dialog when one of them is pressed like you are wanting. Hope this helps!

If you will place your definitions in this order then the code will be compiled

class Ball;

class Player {
public:
    void doSomething(Ball& ball);
private:
};

class Ball {
public:
    Player& PlayerB;
    float ballPosX = 800;
private:

};

void Player::doSomething(Ball& ball) {
    ball.ballPosX += 10;                   // incomplete type error occurs here.
}

int main()
{
}

The definition of function doSomething requires the complete definition of class Ball because it access its data member.

In your code example module Player.cpp has no access to the definition of class Ball so the compiler issues an error.

pubspec.yaml:

dependencies:
  intl:

main.dart:

import 'package:intl/intl.dart'; // for date format
import 'package:intl/date_symbol_data_local.dart'; // for other locales

void main() {
  var now = DateTime.now();
  print(DateFormat().format(now)); // This will return date using the default locale
  print(DateFormat('yyyy-MM-dd hh:mm:ss').format(now));
  print(DateFormat.yMMMMd().format(now)); // print long date 
  print(DateFormat.yMd().format(now)); // print short date 
  print(DateFormat.jms().format(now)); // print time 

  initializeDateFormatting('es'); // This will initialize Spanish locale
  print(DateFormat.yMMMMd('es').format(now)); // print long date in Spanish format
  print(DateFormat.yMd('es').format(now)); // print short date in Spanish format
  print(DateFormat.jms('es').format(now)); // print time in Spanish format
}

There is no need to use AS, just use:

SELECT table1.price Table1 Price, table2.price Table2 Price, .....

Yes, it is possible.

try:
   ...
except FirstException:
   handle_first_one()

except SecondException:
   handle_second_one()

except (ThirdException, FourthException, FifthException) as e:

except Exception:
   handle_all_other_exceptions()

See: http://docs.python.org/tutorial/errors.html

The "as" keyword is used to assign the error to a variable so that the error can be investigated more thoroughly later on in the code. Also note that the parentheses for the triple exception case are needed in python 3. This page has more info: Catch multiple exceptions in one line (except block)

I got it work on both running jar and in IDE by writing as

InputStream schemaStream = 
      ProductUtil.class.getClassLoader().getResourceAsStream(jsonSchemaPath);
byte[] buffer = new byte[schemaStream.available()];
schemaStream.read(buffer);

File tempFile = File.createTempFile("com/package/schema/testSchema", "json");
tempFile.deleteOnExit();
FileOutputStream out = new FileOutputStream(tempFile);
out.write(buffer);

If you have a number, for example 65, and if you want to get the corresponding ASCII character, you can use the chr function, like this

>>> chr(65)
'A'

similarly if you have 97,

>>> chr(97)
'a'

EDIT: The above solution works for 8 bit characters or ASCII characters. If you are dealing with unicode characters, you have to specify unicode value of the starting character of the alphabet to ord and the result has to be converted using unichr instead of chr.

>>> print unichr(ord(u'\u0B85'))
?

>>> print unichr(1 + ord(u'\u0B85'))
?

NOTE: The unicode characters used here are of the language called "Tamil", my first language. This is the unicode table for the same http://www.unicode.org/charts/PDF/U0B80.pdf

Use JpaRepository or CrudRepository as repository interface:

@Repository
public interface CustomerRepository extends JpaRepository<Customer, Integer> {

    @Query("SELECT t from Customer t where LOWER(t.name) LIKE %:name%")
    public List<Customer> findByName(@Param("name") String name);

}


@Service(value="customerService")
public class CustomerServiceImpl implements CustomerService {

    private CustomerRepository customerRepository;
    
    //...

    @Override
    public List<Customer> pattern(String text) throws Exception {
        return customerRepository.findByName(text.toLowerCase());
    }
}

A simple solution without need for require which solves the multiple period extension problem:

var filename = 'file.with.long.extension';
var ext = filename.substring(filename.indexOf('.')); 
//ext = '.with.long.extension'

Or if you don't want the leading dot:

var filename = 'file.with.long.extension';
var ext = filename.substring(filename.indexOf('.')+1); 
//ext = 'with.long.extension'

Make sure to test that the file has an extension too.

To get current date/time in javascript:

var date = new Date();

If you need milliseconds for easy server-side interpretation use

var value = date.getTime();

For formatting dates into a user readable string see this

Then just write to hidden field:

document.getElementById("DATE").value = value;

Another simple solution is to add jackson-databind dependency in POM.

    <dependency>
        <groupId>com.fasterxml.jackson.core</groupId>
        <artifactId>jackson-databind</artifactId>
        <version>2.8.1</version>
    </dependency>

Keep Rest of the code as it is.

Array.prototype.getIndex = function (obj) {
    for (var i = 0; i < this.length; i++) {
        if (this[i][Id] == obj.Id) {
            return i;
        }
    }
    return -1;
}

List.getIndex(obj);

Please try this. Maybe this could help you. It works for me.

string sValue = (range.Cells[_row, _column] as Microsoft.Office.Interop.Excel.Range).Value2.ToString();
//_row,_column your column & row number 
//eg: string sValue = (sheet.Cells[i + 9, 12] as Microsoft.Office.Interop.Excel.Range).Value2.ToString();
//sValue has your value

As the others said, most of the time you won't want to do that because it doesn't copy the assembly to your project and it won't deploy with your project. However, if you're like me, and trying to add a reference that all target machines have in their GAC but it's not a .NET Framework assembly:

1. Open the windows Run dialog (Windows Key + r)
2. Type C:\Windows\assembly\gac_msil. This is some sort of weird hack that lets you browse your GAC. You can only get to it through the run dialog. Hopefully my spreading this info doesn't eventually cause Microsoft to patch it and block it. (Too paranoid? :P)
3. Find your assembly and copy its path from the address bar.
4. Open the Add Reference dialog in Visual Studio and choose the Browse tab.
5. Paste in the path to your GAC assembly.

I don't know if there's an easier way, but I haven't found it. I also frequently use step 1-3 to place .pdb files with their GAC assemblies to make sure they're not lost when I later need to use Remote Debugger.

[[ $list =~ (^|[[:space:]])$x($|[[:space:]]) ]] && echo 'yes' || echo 'no'

or create a function:

contains() {
    [[ $1 =~ (^|[[:space:]])$2($|[[:space:]]) ]] && exit(0) || exit(1)
}

to use it:

contains aList anItem
echo $? # 0: match, 1: failed

I believe this snippet will also be helpful in a situation where the dates comparison spans more than two entries.

static final int COMPARE_EARLIEST = 0;

static final int COMPARE_MOST_RECENT = 1;


public LocalDate getTargetDate(List<LocalDate> datesList, int comparatorType) { 
   LocalDate refDate = null;
   switch(comparatorType)
   {
       case COMPARE_EARLIEST:         
       //returns the most earliest of the date entries
          refDate = (LocalDate) datesList.stream().min(Comparator.comparing(item -> 
                      item.toDateTimeAtCurrentTime())).get();
          break;

       case COMPARE_MOST_RECENT:
          //returns the most recent of the date entries 
          refDate = (LocalDate) datesList.stream().max(Comparator.comparing(item -> 
                    item.toDateTimeAtCurrentTime())).get();
          break;
   }

   return refDate;
}

I had the same problem and this is my solution. I had the following code:

se.GiftDescription = rs.getString(1);
se.GiftAmount = rs.getInt(2);

And I changed it to:

se.GiftDescription = rs.getString("DESCRIPTION");
se.GiftAmount = rs.getInt("AMOUNT");

And the problem was, after I restarted my PC, the column positions changed. That's why I got this error.

public Image Base64ToImage(string base64String)
{
   // Convert Base64 String to byte[]
    byte[] imageBytes = Convert.FromBase64String(base64String);
    MemoryStream ms = new MemoryStream(imageBytes, 0, imageBytes.Length);

    // Convert byte[] to Image
    ms.Write(imageBytes, 0, imageBytes.Length);
    Image image = Image.FromStream(ms, true);

    return image;
}

If you like Vim, it has built-in syntax highlighting for the syslog file, e.g. it will highlight error messages in red.

vi +'syntax on' /var/log/syslog

I've struggled with this issue for a few days and finally the light bulb clicked. The KEY to being able to change the URL of a webservice at runtime is overriding the constructor, which I did with a partial class declaration. The above, setting the URL behavior to Dynamic must also be done.

This basically creates a web-service wrapper where if you have to reload web service at some point, via add service reference, you don't loose your work. The Microsoft help for Partial classes specially states that part of the reason for this construct is to create web service wrappers. http://msdn.microsoft.com/en-us/library/wa80x488(v=vs.100).aspx

// Web Service Wrapper to override constructor to use custom ConfigSection 
// app.config values for URL/User/Pass
namespace myprogram.webservice
{
    public partial class MyWebService
    {
        public MyWebService(string szURL)
        {
            this.Url = szURL;
            if ((this.IsLocalFileSystemWebService(this.Url) == true))
            {
                this.UseDefaultCredentials = true;
                this.useDefaultCredentialsSetExplicitly = false;
            }
            else
            {
                this.useDefaultCredentialsSetExplicitly = true;
            }
        }
    }
}

A short and convenient way to convert a String to its Hexadecimal notation is:

public static void main(String... args){
String str = "Hello! This is test string.";
char ch[] = str.toCharArray();
StringBuilder sb = new StringBuilder();
    for (int i = 0; i < ch.length; i++) {
        sb.append(Integer.toHexString((int) ch[i]));
    }
    System.out.println(sb.toString());
}

You can achieve this by deploying something at a higher layer than namespaced Services, like the service loadbalancer https://github.com/kubernetes/contrib/tree/master/service-loadbalancer. If you want to restrict it to a single namespace, use "--namespace=ns" argument (it defaults to all namespaces: https://github.com/kubernetes/contrib/blob/master/service-loadbalancer/service_loadbalancer.go#L715). This works well for L7, but is a little messy for L4.

I was getting a consistent 15 second delay on the first request after 4 minutes of inactivity. My problem was that my app was using Windows Integrated Authentication to SQL Server and the service profile was in a different domain than the server. This caused a cross-domain authentication from IIS to SQL upon app initialization - and this was the real source of my delay. I changed to using a SQL login instead of windows authentication. The delay was immediately gone. I still have all the app initialization settings in place to help improve performance but they may have not been needed at all in my case.

Using leech's answer with indexOf (to support IE)

This is using what leech talked about, but making it work for IE (IE doesn't support matches):

function closest(el, selector, stopSelector) {
  var retval = null;
  while (el) {
    if (el.className.indexOf(selector) > -1) {
      retval = el;
      break
    } else if (stopSelector && el.className.indexOf(stopSelector) > -1) {
      break
    }
    el = el.parentElement;
  }
  return retval;
}

It's not perfect, but it works if the selector is unique enough so it won't accidentally match the incorrect element.

there is no native interfaces in JavaScript, there are several ways to simulate an interface. i have written a package that does it

you can see the implantation here

Apply these two things.

1. You need to set the character set of your database to be utf8.

2. You need to call the mysql_set_charset('utf8') in the file where you made the connection with the database and right after the selection of database like mysql_select_db use the mysql_set_charset. That will allow you to add and retrieve data properly in whatever the language.

The folder being password protected has nothing to do with PHP!

The method being used is called "Basic Authentication". There are no cross-browser ways to "logout" from it, except to ask the user to close and then open their browser...

Here's how you you could do it in PHP instead (fully remove your Apache basic auth in .htaccess or wherever it is first):

login.php:

<?php
session_start();
//change 'valid_username' and 'valid_password' to your desired "correct" username and password
if (! empty($_POST) && $_POST['user'] === 'valid_username' && $_POST['pass'] === 'valid_password')
{
    $_SESSION['logged_in'] = true;
    header('Location: /index.php');
}
else
{
    ?>

    <form method="POST">
    Username: <input name="user" type="text"><br>
    Password: <input name="pass" type="text"><br><br>
    <input type="submit" value="submit">
    </form>

    <?php
}

index.php

<?php
session_start();
if (! empty($_SESSION['logged_in']))
{
    ?>

    <p>here is my super-secret content</p>
    <a href='logout.php'>Click here to log out</a>

    <?php
}
else
{
    echo 'You are not logged in. <a href="login.php">Click here</a> to log in.';
}

logout.php:

<?php
session_start();
session_destroy();
echo 'You have been logged out. <a href="/">Go back</a>';

Obviously this is a very basic implementation. You'd expect the usernames and passwords to be in a database, not as a hardcoded comparison. I'm just trying to give you an idea of how to do the session thing.

Hope this helps you understand what's going on.

You didn't specify how the order is determined, but this will give you a rank value in MySQL:

SELECT t.*,
       @rownum := @rownum +1 AS rank
  FROM TBL_FOO t
  JOIN (SELECT @rownum := 0) r
 WHERE t.name = 'sarmen'

Then you can pick out what rows you want, based on the rank value.

A one-liner is:-

fruitdict = dict(zip(('apple','banana','carrot'), (1,'f', '3'))

The default configuration of most SMTP servers is not to relay from an untrusted source to outside domains. For example, imagine that you contact the SMTP server for foo.com and ask it to send a message to [email protected]. Because the SMTP server doesn't really know who you are, it will refuse to relay the message. If the server did do that for you, it would be considered an open relay, which is how spammers often do their thing.

If you contact the foo.com mail server and ask it to send mail to [email protected], it might let you do it. It depends on if they trust that you're who you say you are. Often, the server will try to do a reverse DNS lookup, and refuse to send mail if the IP you're sending from doesn't match the IP address of the MX record in DNS. So if you say that you're the bar.com mail server but your IP address doesn't match the MX record for bar.com, then it will refuse to deliver the message.

You'll need to talk to the administrator of that SMTP server to get the authentication information so that it will allow relay for you. You'll need to present those credentials when you contact the SMTP server. Usually it's either a user name/password, or it can use Windows permissions. Depends on the server and how it's configured.

See Unable to send emails to external domain using SMTP for an example of how to send the credentials.

The main difference :

•Activity.dispatchTouchEvent(MotionEvent) - This allows your Activity to intercept all touch events before they are dispatched to the window.
•ViewGroup.onInterceptTouchEvent(MotionEvent) - This allows a ViewGroup to watch events as they are dispatched to child Views.

Unions are great. One clever use of unions I've seen is to use them when defining an event. For example, you might decide that an event is 32 bits.

Now, within that 32 bits, you might like to designate the first 8 bits as for an identifier of the sender of the event... Sometimes you deal with the event as a whole, sometimes you dissect it and compare it's components. unions give you the flexibility to do both.

union Event
{
  unsigned long eventCode;
  unsigned char eventParts[4];
};

You are using the wrong iteration counter, replace inp.charAt(i) with inp.charAt(j).

CGRect rect = label.frame;
rect.size = [label.text sizeWithAttributes:@{NSFontAttributeName : [UIFont fontWithName:label.font.fontName size:label.font.pointSize]}];
label.frame = rect;

Assuming you have two log-files in:

• C:/temp/my.log
• C:/temp/alsoMy.log

cd to C: and use:

grep -r somethingtosearch temp/*.log

It will give you a list like:

temp/my.log:somethingtosearch
temp/alsoMy.log:somethingtosearch1
temp/alsoMy.log:somethingtosearch2

It sounds like what you want is a User who has many Questions.
The Question has many Answers, one of which is the User's Choice.

Is this what you are after?

I would model something like that along these lines:

class User
  has_many :questions
end

class Question
  belongs_to :user
  has_many   :answers
  has_one    :choice, :class_name => "Answer"

  validates_inclusion_of :choice, :in => lambda { answers }
end

class Answer
  belongs_to :question
end

With WinForms you can use the ErrorProvider in conjunction with the Validating event to handle the validation of user input. The Validating event provides the hook to perform the validation and ErrorProvider gives a nice consistent approach to providing the user with feedback on any error conditions.

I've had the same error parsing a string containing \n into JSON. The solution was to use string.replace('\n','\\n')

The Gutenberg Project hosts Webster's Unabridged English Dictionary plus many other public domain literary works. Actually it looks like they've got several versions of the dictionary hosted with copyright from different years. The one I linked has a 2009 copyright. You may want to poke around the site and investigate the different versions of Webster's dictionary.

Since you say you want to access by position once your data is read in, you should know about R's subsetting/ indexing functions.

The easiest is

df[row,column]
#example
df[1:5,] #rows 1:5, all columns
df[,5] #all rows, column 5. 

Other methods are here. I personally use the dplyr package for intuitive data manipulation (not by position).

Here is a method that uses stamper and absolute coordinates showed in the different PDF clients (Adobe, FoxIt and etc. )

public static void AddTextToPdf(string inputPdfPath, string outputPdfPath, string textToAdd, System.Drawing.Point point)
    {
        //variables
        string pathin = inputPdfPath;
        string pathout = outputPdfPath;

        //create PdfReader object to read from the existing document
        using (PdfReader reader = new PdfReader(pathin))
        //create PdfStamper object to write to get the pages from reader 
        using (PdfStamper stamper = new PdfStamper(reader, new FileStream(pathout, FileMode.Create)))
        {
            //select two pages from the original document
            reader.SelectPages("1-2");

            //gettins the page size in order to substract from the iTextSharp coordinates
            var pageSize = reader.GetPageSize(1);

            // PdfContentByte from stamper to add content to the pages over the original content
            PdfContentByte pbover = stamper.GetOverContent(1);

            //add content to the page using ColumnText
            Font font = new Font();
            font.Size = 45;

            //setting up the X and Y coordinates of the document
            int x = point.X;
            int y = point.Y;

            y = (int) (pageSize.Height - y);

            ColumnText.ShowTextAligned(pbover, Element.ALIGN_CENTER, new Phrase(textToAdd, font), x, y, 0);
        }
    }

You can use shorthand syntax as of Twig 1.12.0

{{ foo ?: 'no' }} is the same as {{ foo ? foo : 'no' }}
{{ foo ? 'yes' }} is the same as {{ foo ? 'yes' : '' }}

Perhaps use tikz.

Search for a null value by using \00

For example:

ldapsearch -D cn=admin -w pass -s sub -b ou=users,dc=acme 'manager=\00' uid manager

Make sure if you use the null value on the command line to use quotes around it to prevent the OS shell from sending a null character to LDAP. For example, this won't work:

 ldapsearch -D cn=admin -w pass -s sub -b ou=users,dc=acme manager=\00 uid manager

There are various sites that reference this, along with other special characters. Example:

• http://www.ldapexplorer.com/en/manual/109010000-ldap-filter-syntax.htm
• http://msdn.microsoft.com/en-us/library/windows/desktop/aa746475%28v=vs.85%29.aspx

Your should create ptr as follows:

char *ptr;

You have created ptr as an array of pointers to chars. The above creates a single pointer to a char.

Edit: complete code should be:

char *ptr;
char arr[5] = {'a','b','c','d','e'};
ptr = arr;
printf("\nvalue:%c", *(ptr+0));

You can find an example below. Basically you attach a function to window's scroll event and trace scrollTop property and if it's higher than desired threshold you apply position: fixed and some other css properties.

jQuery(function($) {_x000D_
  $(window).scroll(function fix_element() {_x000D_
    $('#target').css(_x000D_
      $(window).scrollTop() > 100_x000D_
        ? { 'position': 'fixed', 'top': '10px' }_x000D_
        : { 'position': 'relative', 'top': 'auto' }_x000D_
    );_x000D_
    return fix_element;_x000D_
  }());_x000D_
});

As noted in the comments, just running

./gradlew

worked for me. Adding the ./ tells it to look in the current directory since it isn't in the path.

Windows PowerShell

.\gradlew

You can always write the code in VBA that updates similarly. I had this problem too, and my workaround was making a select query, with all the joins, that had all the data I was looking for to be able to update, making that a recordset and running the update query repeatedly as an update query of only the updating table, only searching the criteria you're looking for

    Dim updatingItems As Recordset
    Dim clientName As String
    Dim tableID As String
    Set updatingItems = CurrentDb.OpenRecordset("*insert SELECT SQL here*");", dbOpenDynaset)
    Do Until updatingItems .EOF
        clientName = updatingItems .Fields("strName")
        tableID = updatingItems .Fields("ID")
        DoCmd.RunSQL "UPDATE *ONLY TABLE TO UPDATE* SET *TABLE*.strClientName= '" & clientName & "' WHERE (((*TABLE*.ID)=" & tableID & "))"
        updatingItems.MoveNext
    Loop

I'm only doing this to about 60 records a day, doing it to a few thousand could take much longer, as the query is running from start to finish multiple times, instead of just selecting an overall group and making changes. You might need ' ' around the quotes for tableID, as it's a string, but I'm pretty sure this is what worked for me.

You can also use;

 List<KeyValuePair<string, string>> Mappings;

There is a, perhaps subtle, but important misconception in a number these answers. I thought I'd add my answer to clear it up.

What is HEAD?

HEAD is YOU

HEADis a symbolic reference pointing to wherever you are in your commit history. It follows you wherever you go, whatever you do, like a shadow. If you make a commit, HEAD will move. If you checkout something, HEAD will move. Whatever you do, if you have moved somewhere new in your commit history, HEAD has moved along with you. To address one common misconception: you cannot detach yourself from HEAD. That is not what a detached HEAD state is. If you ever find yourself thinking: "oh no, i'm in detached HEAD state! I've lost my HEAD!" Remember, it's your HEAD. HEAD is you. You haven't detached from the HEAD, you and your HEAD have detached from something else.

What can HEAD attach to?

HEAD can point to a commit, yes, but typically it does not. Let me say that again. Typically HEAD does not point to a commit. It points to a branch reference. It is attached to that branch, and when you do certain things (e.g., commit or reset), the attached branch will move along with HEAD. You can see what it is pointing to by looking under the hood.

cat .git/HEAD

Normally you'll get something like this:

ref: refs/heads/master

Sometimes you'll get something like this:

a3c485d9688e3c6bc14b06ca1529f0e78edd3f86

That's what happens when HEAD points directly to a commit. This is called a detached HEAD, because HEAD is pointing to something other than a branch reference. If you make a commit in this state, master, no longer being attached to HEAD, will no longer move along with you. It does not matter where that commit is. You could be on the same commit as your master branch, but if HEAD is pointing to the commit rather than the branch, it is detached and a new commit will not be associated with a branch reference.

You can look at this graphically if you try the following exercise. From a git repository, run this. You'll get something slightly different, but they key bits will be there. When it is time to checkout the commit directly, just use whatever abbreviated hash you get from the first output (here it is a3c485d).

git checkout master
git log --pretty=format:"%h:  %d" -1
# a3c485d:   (HEAD -> master)

git checkout a3c485d -q # (-q is for dramatic effect)
git log --pretty=format:"%h:  %d" -1   
# a3c485d:   (HEAD, master)

OK, so there is a small difference in the output here. Checking out the commit directly (instead of the branch) gives us a comma instead of an arrow. What do you think, are we in a detached HEAD state? HEAD is still referring to a specific revision that is associated with a branch name. We're still on the master branch, aren't we?

Now try:

git status
# HEAD detached at a3c485d

Nope. We're in 'detached HEAD' state.

You can see the same representation of (HEAD -> branch) vs. (HEAD, branch) with git log -1.

In conclusion

HEAD is you. It points to whatever you checked out, wherever you are. Typically that is not a commit, it is a branch. If HEAD does point to a commit (or tag), even if it's the same commit (or tag) that a branch also points to, you (and HEAD) have been detached from that branch. Since you don't have a branch attached to you, the branch won't follow along with you as you make new commits. HEAD, however, will.

note for php 7 users, add this to your httpd.conf file:

PDFCreator has a COM component, callable from .NET or VBScript (samples included in the download).

But, it seems to me that a printer is just what you need - just mix that with Word's automation, and you should be good to go.

This was a known bug in version(s) of PHP . Depending on your server environment, you can try setting the sessions folder to 777:

/var/lib/php/session (your location may vary)

I ended up using this workaround:

session_save_path('/path/not/accessable_to_world/sessions');
ini_set('session.gc_probability', 1);

You will have to create this folder and make it writeable. I havent messed around with the permissions much, but 777 worked for me (obviously).

Make sure the place where you are storing your sessions isn't accessible to the world.

This solution may not work for everyone, but I hope it helps some people!

public static Bitmap createSingleImageFromMultipleImages(Bitmap firstImage, Bitmap secondImage, ImageView secondImageView){

    Bitmap result = Bitmap.createBitmap(firstImage.getWidth(), firstImage.getHeight(), firstImage.getConfig());
    Canvas canvas = new Canvas(result);
    canvas.drawBitmap(firstImage, 0f, 0f, null);
    canvas.drawBitmap(secondImage, secondImageView.getX(), secondImageView.getY(), null);

    return result;
}

You can also use this

let str = "hello single ' double \" and slash \\ yippie";

let escapeStr = escape(str);
document.write("<b>str : </b>"+str);
document.write("<br/><b>escapeStr : </b>"+escapeStr);
document.write("<br/><b>unEscapeStr : </b> "+unescape(escapeStr));

A pretty simple solution I came up with: (Python 3)

def only_letters(tested_string):
    for letter in tested_string:
        if letter not in "abcdefghijklmnopqrstuvwxyz":
            return False

<div id="container"></div>

also, you can copy all attributes from the string(based on the question, you get iframe as a string from a server) which contains <iframe> tag and pass it to new <iframe> tag, like that

/**_x000D_
 * getAttrs_x000D_
 * returns all attributes from TAG string_x000D_
 * @return Object_x000D_
 */_x000D_
const getAttrs = (iframeTag) => {_x000D_
  var doc = document.createElement('div');_x000D_
  doc.innerHTML = iframeTag;_x000D_
_x000D_
  const iframe = doc.getElementsByTagName('iframe')[0];_x000D_
  return [].slice_x000D_
    .call(iframe.attributes)_x000D_
    .reduce((attrs, element) => {_x000D_
      attrs[element.name] = element.value;_x000D_
      return attrs;_x000D_
    }, {});_x000D_
}_x000D_
_x000D_
const Component = React.createClass({_x000D_
  render: function() {_x000D_
    return (_x000D_
      <div>_x000D_
        <iframe {...getAttrs(this.props.iframe) } />_x000D_
      </div>_x000D_
    );_x000D_
  }_x000D_
});_x000D_
_x000D_
const iframe = '<iframe src="https://www.example.com/show?data..." width="540" height="450"></iframe>'; _x000D_
_x000D_
ReactDOM.render(_x000D_

Beware! While it's true that "sort -u" and "sort|uniq" are equivalent, any additional options to sort can break the equivalence. Here's an example from the coreutils manual:

For example, 'sort -n -u' inspects only the value of the initial numeric string when checking for uniqueness, whereas 'sort -n | uniq' inspects the entire line.

Similarly, if you sort on key fields, the uniqueness test used by sort won't necessarily look at the entire line anymore. After being bitten by that bug in the past, these days I tend to use "sort|uniq" when writing Bash scripts. I'd rather have higher I/O overhead than run the risk that someone else in the shop won't know about that particular pitfall when they modify my code to add additional sort parameters.

You should check the EOF after reading from file.

fscanf_s                   // read from file
while(condition)           // check EOF
{
   fscanf_s               // read from file
}

Also, you can use bool method(s)

Query :

DataTable tempData = (DataTable)grdUsageRecords.DataSource;
var query = from r in tempData.AsEnumerable()
            where isValid(Field<string>("UserName"))// && otherMethod() && otherMethod2()                           
            select r;   

        DataTable newDT = query.CopyToDataTable();

Method:

bool isValid(string userName)
{
    if(userName == "XXXX" || userName == "YYYY")
        return false;
    else return true;
}
