the answer is

Dictionary

take look at my function, its simple add uses most important member functions inside Dictionary

this function return false if the list contain Duplicates items

 public static bool HasDuplicates<T>(IList<T> items)
    {
        Dictionary<T, bool> mp = new Dictionary<T, bool>();
        for (int i = 0; i < items.Count; i++)
        {
            if (mp.ContainsKey(items[i]))
            {
                return true; // has duplicates
            }
            mp.Add(items[i], true);
        }
        return false; // no duplicates
    }

Use PowerShell to do anything smarter for a DOS prompt. Here, I've shown how to batch rename all the files and directories in the current directory that contain spaces by replacing them with _ underscores.

Dir |
Rename-Item -NewName { $_.Name -replace " ","_" }

EDIT :
Optionally, the Where-Object command can be used to filter out ineligible objects for the successive cmdlet (command-let). The following are some examples to illustrate the flexibility it can afford you:

• To skip any document files

  Dir |
  Where-Object { $_.Name -notmatch "\.(doc|xls|ppt)x?$" } |
  Rename-Item -NewName { $_.Name -replace " ","_" }
  

• To process only directories (pre-3.0 version)

  Dir |
  Where-Object { $_.Mode -match "^d" } |
  Rename-Item -NewName { $_.Name -replace " ","_" }
  

  PowerShell v3.0 introduced new Dir flags. You can also use Dir -Directory there.

• To skip any files already containing an underscore (or some other character)

  Dir |
  Where-Object { -not $_.Name.Contains("_") } |
  Rename-Item -NewName { $_.Name -replace " ","_" }
  

You can use CORT (www.softcraftltd.co.uk/cort). This tool allows to CREATE OR REPLACE table in Oracle. It looks like:

create /*# or replace */ table MyTable(
  ... -- standard table definition
);

It preserves data.

I'd probably use a LEFT JOIN, which will return rows even if there's no match, and then you can select only the rows with no match by checking for NULLs.

So, something like:

SELECT V.*
FROM voter V LEFT JOIN elimination E ON V.id = E.voter_id
WHERE E.voter_id IS NULL

Whether that's more or less efficient than using a subquery depends on optimization, indexes, whether its possible to have more than one elimination per voter, etc.

Works fine for me

Make sure your jquery is inside $(document).ready function or similar.

Also you can improve your code by using jquery data

$('#amount').data('min','1000');

<div id="amount" data-min=""></div>

Update,

A working example of your full code (pretty much) here. http://jsfiddle.net/blowsie/c6VAy/3/

Here's a very simple solution without too much code using a very simple map of diacritics that includes some or all that map to ascii equivalents containing more than one character, i.e. Æ => AE, ? => ffi, etc... Also included some very basic functional tests

typedef enum {
kCircle,
kRectangle,
kOblateSpheroid
} ShapeType;

then you can use it like :-

 ShapeType shape;

and

 enum {
    kCircle,
    kRectangle,
    kOblateSpheroid
} 
ShapeType;

now you can use it like:-

enum ShapeType shape;

You can change this in the page load.

My intention is that when the page comes to the load function, switch the links (the current link in the required one)

1. If you are Deleting All the rows in that table the simplest option is to Truncate table, something like

   TRUNCATE TABLE LargeTable
   GO
   

   Truncate table will simply empty the table, you cannot use WHERE clause to limit the rows being deleted and no triggers will be fired.

2. On the other hand if you are deleting more than 80-90 Percent of the data, say if you have total of 11 Million rows and you want to delete 10 million another way would be to Insert these 1 million rows (records you want to keep) to another staging table. Truncate this Large table and Insert back these 1 Million rows.

3. Or if permissions/views or other objects which has this large table as their underlying table doesnt get affected by dropping this table you can get these relatively small amount of the rows into another table drop this table and create another table with same schema and import these rows back into this ex-Large table.

4. One last option I can think of is to change your database's Recovery Mode to SIMPLE and then delete rows in smaller batches using a while loop something like this..

   DECLARE @Deleted_Rows INT;
   SET @Deleted_Rows = 1;
   
   
   WHILE (@Deleted_Rows > 0)
     BEGIN
      -- Delete some small number of rows at a time
        DELETE TOP (10000)  LargeTable 
        WHERE readTime < dateadd(MONTH,-7,GETDATE())
   
     SET @Deleted_Rows = @@ROWCOUNT;
   END
   

and dont forget to change the Recovery mode back to full and I think you have to take a backup to make it fully affective (the change or recovery modes).

The META-INF folder is the home for the MANIFEST.MF file. This file contains meta data about the contents of the JAR. For example, there is an entry called Main-Class that specifies the name of the Java class with the static main() for executable JAR files.

with open("filename.txt", "w+") as file:
  for line in file:
    print line

This with statement automatically opens and closes it for you and you can iterate over the lines of the file with a simple for loop

I had the same question but applying the provided solutions changed the file to write in. Once I selected the new excel file, I was also writing in that file and not in my original file. My solution for this issue is below:

Sub GetData()

    Dim excelapp As Application
    Dim source As Workbook
    Dim srcSH1 As Worksheet
    Dim sh As Worksheet
    Dim path As String
    Dim nmr As Long
    Dim i As Long

    nmr = 20

    Set excelapp = New Application

    With Application.FileDialog(msoFileDialogOpen)
        .AllowMultiSelect = False
        .Filters.Add "Excel Files", "*.xlsx; *.xlsm; *.xls; *.xlsb", 1
        .Show
        path = .SelectedItems.Item(1)
    End With

    Set source = excelapp.Workbooks.Open(path)
    Set srcSH1 = source.Worksheets("Sheet1")
    Set sh = Sheets("Sheet1")

    For i = 1 To nmr
        sh.Cells(i, "A").Value = srcSH1.Cells(i, "A").Value
    Next i

End Sub

With excelapp a new application will be called. The with block sets the path for the external file. Finally, I set the external Workbook with source and srcSH1 as a Worksheet within the external sheet.

Just give the individual button elements a unique name. When pressed, the button's name is available as a request parameter the usual way like as with input elements.

You only need to make sure that the button inputs have type="submit" as in <input type="submit"> and <button type="submit"> and not type="button", which only renders a "dead" button purely for onclick stuff and all.

E.g.

<form action="${pageContext.request.contextPath}/myservlet" method="post">
    <input type="submit" name="button1" value="Button 1" />
    <input type="submit" name="button2" value="Button 2" />
    <input type="submit" name="button3" value="Button 3" />
</form>

with

@WebServlet("/myservlet")
public class MyServlet extends HttpServlet {

    @Override
    protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        MyClass myClass = new MyClass();

        if (request.getParameter("button1") != null) {
            myClass.method1();
        } else if (request.getParameter("button2") != null) {
            myClass.method2();
        } else if (request.getParameter("button3") != null) {
            myClass.method3();
        } else {
            // ???
        }

        request.getRequestDispatcher("/WEB-INF/some-result.jsp").forward(request, response);
    }

}

Alternatively, use <button type="submit"> instead of <input type="submit">, then you can give them all the same name, but an unique value. The value of the <button> won't be used as label, you can just specify that yourself as child.

E.g.

<form action="${pageContext.request.contextPath}/myservlet" method="post">
    <button type="submit" name="button" value="button1">Button 1</button>
    <button type="submit" name="button" value="button2">Button 2</button>
    <button type="submit" name="button" value="button3">Button 3</button>
</form>

with

@WebServlet("/myservlet")
public class MyServlet extends HttpServlet {

    @Override
    protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        MyClass myClass = new MyClass();
        String button = request.getParameter("button");

        if ("button1".equals(button)) {
            myClass.method1();
        } else if ("button2".equals(button)) {
            myClass.method2();
        } else if ("button3".equals(button)) {
            myClass.method3();
        } else {
            // ???
        }

        request.getRequestDispatcher("/WEB-INF/some-result.jsp").forward(request, response);
    }

}

Most likely these classes are already defined by Bootstrap, make sure that your CSS file that you want to override the classes with is called AFTER the Bootstrap CSS.

<link rel="stylesheet" href="css/bootstrap.css" /> <!-- Call Bootstrap first -->
<link rel="stylesheet" href="css/bootstrap-override.css" /> <!-- Call override CSS second -->

Otherwise, you can put !important at the end of your CSS like this: color:#ffffff!important; but I would advise against using !important at all costs.

If you don't want to output a Python script every time you save, or you don't want to restart the IPython kernel:

On the command line, you can use nbconvert:

$ jupyter nbconvert --to script [YOUR_NOTEBOOK].ipynb

As a bit of a hack, you can even call the above command in an IPython notebook by pre-pending ! (used for any command line argument). Inside a notebook:

!jupyter nbconvert --to script config_template.ipynb

Before --to script was added, the option was --to python or --to=python, but it was renamed in the move toward a language-agnostic notebook system.

It will store value of number of characters printed so far in that printf() function.

Example:

int a;
printf("Hello World %n \n", &a);
printf("Characters printed so far = %d",a);

The output of this program will be

Hello World
Characters printed so far = 12

Edit: Answer updated to reflect changes in recent versions of NAudio

It's possible using the NAudio open source .NET audio library I have written. It looks for an ACM codec on your PC to do the conversion. The Mp3FileReader supplied with NAudio currently expects to be able to reposition within the source stream (it builds an index of MP3 frames up front), so it is not appropriate for streaming over the network. However, you can still use the MP3Frame and AcmMp3FrameDecompressor classes in NAudio to decompress streamed MP3 on the fly.

I have posted an article on my blog explaining how to play back an MP3 stream using NAudio. Essentially you have one thread downloading MP3 frames, decompressing them and storing them in a BufferedWaveProvider. Another thread then plays back using the BufferedWaveProvider as an input.

There's a third (and potentially much easier) option. If you want to spin up multiple instances of a single program, using a Unix-style command processor like Xargs or GNU Parallel can make that a fairly straightforward process.

There's a win32 Xargs clone called PPX2 that makes this fairly straightforward.

For instance, if you wanted to transcode a directory of video files, you could run the command:

dir /b *.mpg |ppx2 -P 4 -I {} -L 1 ffmpeg.exe -i "{}" -quality:v 1 "{}.mp4"

Picking this apart, dir /b *.mpg grabs a list of .mpg files in my current directory, the | operator pipes this list into ppx2, which then builds a series of commands to be executed in parallel; 4 at a time, as specified here by the -P 4 operator. The -L 1 operator tells ppx2 to only send one line of our directory listing to ffmpeg at a time.

After that, you just write your command line (ffmpeg.exe -i "{}" -quality:v 1 "{}.mp4"), and {} gets automatically substituted for each line of your directory listing.

It's not universally applicable to every case, but is a whole lot easier than using the batch file workarounds detailed above. Of course, if you're not dealing with a list of files, you could also pipe the contents of a textfile or any other program into the input of pxx2.

I think 'input' simply works here the same way 'oninput' does in the DOM Level O Event Model.

Incidentally:

Just as silkfire commented it, I too googled for 'jQuery input event'. Thus I was led to here and astounded to learn that 'input' is an acceptable parameter to jquery's bind() command. In jQuery in Action (p. 102, 2008 ed.) 'input' is not mentionned as a possible event (against 20 others, from 'blur' to 'unload'). It is true that, on p. 92, the contrary could be surmised from rereading (i.e. from a reference to different string identifiers between Level 0 and Level 2 models). That is quite misleading.

Use this inside your application tag in manifest or inside your Activity tag.

android:theme="@style/AppTheme.NoActionBar"

simple structure, easily adaptable, easy maintenance.

std::string stringIn = "my,csv,,is 10233478,separated,by commas";
std::vector<std::string> commaSeparated(1);
int commaCounter = 0;
for (int i=0; i<stringIn.size(); i++) {
    if (stringIn[i] == ",") {
        commaSeparated.push_back("");
        commaCounter++;
    } else {
        commaSeparated.at(commaCounter) += stringIn[i];
    }
}

in the end you will have a vector of strings with every element in the sentence separated by spaces. empty strings are saved as separate items.

The previous answers explain type parameters (T, E, etc.), but don't explain the wildcard, "?", or the differences between them, so I'll address that.

First, just to be clear: the wildcard and type parameters are not the same. Where type parameters define a sort of variable (e.g., T) that represents the type for a scope, the wildcard does not: the wildcard just defines a set of allowable types that you can use for a generic type. Without any bounding (extends or super), the wildcard means "use any type here".

The wildcard always come between angle brackets, and it only has meaning in the context of a generic type:

public void foo(List<?> listOfAnyType) {...}  // pass a List of any type

never

public <?> ? bar(? someType) {...}  // error. Must use type params here

or

public class MyGeneric ? {      // error
    public ? getFoo() { ... }   // error
    ...
}

It gets more confusing where they overlap. For example:

List<T> fooList;  // A list which will be of type T, when T is chosen.
                  // Requires T was defined above in this scope
List<?> barList;  // A list of some type, decided elsewhere. You can do
                  // this anywhere, no T required.

There's a lot of overlap in what's possible with method definitions. The following are, functionally, identical:

public <T> void foo(List<T> listOfT) {...}
public void bar(List<?> listOfSomething)  {...}

So, if there's overlap, why use one or the other? Sometimes, it's honestly just style: some people say that if you don't need a type param, you should use a wildcard just to make the code simpler/more readable. One main difference I explained above: type params define a type variable (e.g., T) which you can use elsewhere in the scope; the wildcard doesn't. Otherwise, there are two big differences between type params and the wildcard:

Type params can have multiple bounding classes; the wildcard cannot:

public class Foo <T extends Comparable<T> & Cloneable> {...}

The wildcard can have lower bounds; type params cannot:

public void bar(List<? super Integer> list) {...}

In the above the List<? super Integer> defines Integer as a lower bound on the wildcard, meaning that the List type must be Integer or a super-type of Integer. Generic type bounding is beyond what I want to cover in detail. In short, it allows you to define which types a generic type can be. This makes it possible to treat generics polymorphically. E.g. with:

public void foo(List<? extends Number> numbers) {...}

You can pass a List<Integer>, List<Float>, List<Byte>, etc. for numbers. Without type bounding, this won't work -- that's just how generics are.

Finally, here's a method definition which uses the wildcard to do something that I don't think you can do any other way:

public static <T extends Number> void adder(T elem, List<? super Number> numberSuper) {
    numberSuper.add(elem);
}

numberSuper can be a List of Number or any supertype of Number (e.g., List<Object>), and elem must be Number or any subtype. With all the bounding, the compiler can be certain that the .add() is typesafe.

If you want to lookup/associate an object with a unique identifier without modifying the underlying object, you can use a WeakMap:

// Note that object must be an object or array,
// NOT a primitive value like string, number, etc.
var objIdMap=new WeakMap, objectCount = 0;
function objectId(object){
  if (!objIdMap.has(object)) objIdMap.set(object,++objectCount);
  return objIdMap.get(object);
}

var o1={}, o2={}, o3={a:1}, o4={a:1};
console.log( objectId(o1) ) // 1
console.log( objectId(o2) ) // 2
console.log( objectId(o1) ) // 1
console.log( objectId(o3) ) // 3
console.log( objectId(o4) ) // 4
console.log( objectId(o3) ) // 3

Using a WeakMap instead of Map ensures that the objects can still be garbage-collected.

Does the following code work for your problem? I've used a foreach with a bit of linq inside to do the combining of lists and assumed that people are equal if their names match, and it seems to print the expected values out when run. Resharper doesn't offer any suggestions to convert the foreach into linq so this is probably as good as it'll get doing it this way.

      List<Person> list2 = new List<Person>
                              {

            list3.Add(person);
         }
      }

      foreach (var person in list3)
      {
         Console.WriteLine("{0} {1} {2} ", person.Name,person.Value,person.Change);
      }
      Console.Read();
   }
}

I used KooiInc's function listed above but I had to use two different input types one 'button' for IE and one 'submit' for FireFox. I am not exactly sure why but it works.

// HTML

<input type="button" id="btnEmailHidden" style="display:none" />
<input type="submit" id="btnEmailHidden2" style="display:none" />

// in JavaScript

var hiddenBtn = document.getElementById("btnEmailHidden");

if (hiddenBtn.fireEvent) {
    hiddenBtn.fireEvent('onclick');
    hiddenBtn[eType]();
}
else {
    // dispatch for firefox + others
    var evObj = document.createEvent('MouseEvent');
    evObj.initEvent(eType, true, true);
    var hiddenBtn2 = document.getElementById("btnEmailHidden2");
    hiddenBtn2.dispatchEvent(evObj);
}

I have search and tried many suggestions but this is what ended up working. If I had some more time I would have liked to investigate why submit works with FF and button with IE but that would be a luxury right now so on to the next problem.

I know it's working for you now @Vantheman6 but this is what worked for me in case it's the same for someone else.

I added to my .env file the details of the mail service I am using. So make sure the following details

MAIL_DRIVER=smtp
MAIL_HOST=smtp.gmail.com
MAIL_PORT=587
[email protected]
MAIL_PASSWORD=MyPassword

in the .env file are accurate.

NOTE: Don't forget to restart your server after editing the .env file so it will pick the new data that you put in there.

Clear config cache with below command:

php artisan config:cache

If you don't restart your server, the .env file will still continue to present the old mail data to the app even though you have made changes that can cause this error.

In python:

def lcm(*args):
    """Calculates lcm of args"""
    biggest = max(args) #find the largest of numbers
    rest = [n for n in args if n != biggest] #the list of the numbers without the largest
    factor = 1 #to multiply with the biggest as long as the result is not divisble by all of the numbers in the rest
    while True:
        #check if biggest is divisble by all in the rest:
        ans = False in [(biggest * factor) % n == 0 for n in rest]
        #if so the clm is found break the loop and return it, otherwise increment factor by 1 and try again
        if not ans:
            break
        factor += 1
    biggest *= factor
    return "lcm of {0} is {1}".format(args, biggest)

>>> lcm(100,23,98)
'lcm of (100, 23, 98) is 112700'
>>> lcm(*range(1, 20))
'lcm of (1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19) is 232792560'

That is a Python bug between "*" and special characters.

Instead of

re.compile(r"\w*")

Try:

re.compile(r"[a-zA-Z0-9]*")

It works, however does not make the same regular expression.

This bug seems to have been fixed between 2.7.5 and 2.7.6.

Since it's essentially a double...

Divide by 60.0 and extract the integral part and the fractional part.

The integral part will be the whole number of minutes.

Multiply the fractional part by 60.0 again.

The result will be the remaining seconds.

If you need just to execute your VLC playback process and only give control back to your application process when it is done and nothing more complex, then i suppose you can use just:

system("The same thing you type into console");

The code below will show difference for found values only, i.e., if years = 0, then it will not show years.

$diffs = [
    'years' => 'y',
    'months' => 'm',
    'days' => 'd',
    'hours' => 'h',
    'minutes' => 'i',
    'seconds' => 's'
];

$interval = $timeout->diff($timein);
$diffArr = [];
foreach ($diffs as $k => $v) {
    $d = $interval->format('%' . $v);
    if ($d > 0) {
        $diffArr[] = $d . ' ' . $k;
    }
}    
$diffStr = implode(', ', $diffArr);
echo 'Difference: ' . ($diffStr == '' ? '0' : $diffStr) . PHP_EOL;

You can try using CSS, it works for me. The attribute placeholder=" " is required here.

<textarea id="myID" placeholder=" "></textarea>
<style>
#myID::-webkit-input-placeholder::before {
    content: "1st line...\A2nd line...\A3rd line...";
}
</style>

Use the wc utility with the print the byte counts (-c) option:

$ SO="stackoverflow"
$ echo -n "$SO" | wc -c
    13

You'll have to use the do not output the trailing newline (-n) option for echo. Otherwise, the newline character will also be counted.

One of the versions you posted actually works for all modern browsers (where CSS selectors level 3 are supported):

div ul:not(:first-child) {
    background-color: #900;
}

If you need to support legacy browsers, or if you are hindered by the :not selector's limitation (it only accepts a simple selector as an argument) then you can use another technique:

Define a rule that has greater scope than what you intend and then "revoke" it conditionally, limiting its scope to what you do intend:

div ul {
    background-color: #900;  /* applies to every ul */
}

div ul:first-child {
    background-color: transparent; /* limits the scope of the previous rule */
}

When limiting the scope use the default value for each CSS attribute that you are setting.

The accepted answer is outdated. So first, pip is preferred over easy_install, (Why use pip over easy_install?). Then follow these steps to install pip on Windows, it's quite easy.

1. Install setuptools:

   curl https://bootstrap.pypa.io/ez_setup.py | python
   

2. Install pip:

   curl https://bootstrap.pypa.io/get-pip.py | python
   

3. Optionally, you can add the path to your environment so that you can use pip anywhere. It's somewhere like C:\Python33\Scripts.

I worked on Access Denied for User 'root'@'localhost' (using password: YES) for several hours, I have found following solution,

The answer to this problem was that in the my.cnf located within
/etc/mysql/my.cnf

the line was either 
bind-address = 127.0.0.1 
            (or)
bind-address = localhost
            (or)
bind-address = 0.0.0.0

I should prefer that 127.0.0.1

I should also prefer 0.0.0.0, it is more flexible 
because which will allow all connections

If you use "axios": "^0.17.1" version you can do like this:

Create instance of axios:

// Default config options
  const defaultOptions = {
    baseURL: <CHANGE-TO-URL>,
    headers: {
      'Content-Type': 'application/json',
    },
  };

  // Create instance
  let instance = axios.create(defaultOptions);

  // Set the AUTH token for any request
  instance.interceptors.request.use(function (config) {
    const token = localStorage.getItem('token');
    config.headers.Authorization =  token ? `Bearer ${token}` : '';
    return config;
  });

Then for any request the token will be select from localStorage and will be added to the request headers.

I'm using the same instance all over the app with this code:

import axios from 'axios';

const fetchClient = () => {
  const defaultOptions = {
    baseURL: process.env.REACT_APP_API_PATH,
    method: 'get',
    headers: {
      'Content-Type': 'application/json',
    },
  };

  // Create instance
  let instance = axios.create(defaultOptions);

  // Set the AUTH token for any request
  instance.interceptors.request.use(function (config) {
    const token = localStorage.getItem('token');
    config.headers.Authorization =  token ? `Bearer ${token}` : '';
    return config;
  });

  return instance;
};

export default fetchClient();

Good luck.

To add Mode.Write:

Mode = Mode | Mode.Write;

A tab is a tab. How many spaces it consumes is a display issue, and depends on the settings of your shell.

If you want to control the width of your data, then you could use the width sub-specifiers in the printf format string. Eg. :

printf("%5d", 2);

It's not a complete solution (if the value is longer than 5 characters, it will not be truncated), but might be ok for your needs.

If you want complete control, you'll probably have to implement it yourself.

At the beginning of stored procedure one should put SET XACT_ABORT ON to instruct Sql Server to automatically rollback transaction in case of error. If ommited or set to OFF one needs to test @@ERROR after each statement or use TRY ... CATCH rollback block.

You can try settings of code::block, there is a complier..., then you select in C mode.

For ssh style urls just add ssh before the url:

yarn add ssh://<whatever>@<xxx>#<branch,tag,commit>

Here is the same way as @Nera suggested to check the class first but instead of using .SD is to use the fast loop of data.table with set as @Matt Dowle solution with added class check.

for (j in seq_len(ncol(DT))){
  if(class(DT[[j]]) == 'factor')
    set(DT, j = j, value = as.character(DT[[j]]))
}

So you want to know if one string contains two other strings?

You could use this extension which also allows to specify the comparison:

public static bool ContainsAll(this string text, StringComparison comparison = StringComparison.CurrentCulture, params string[]parts)
{
    return parts.All(p => text.IndexOf(p, comparison) > -1);
}

Use it in this way (you can also omit the StringComparison):

bool containsAll = d.ContainsAll(StringComparison.OrdinalIgnoreCase, a, b);

That's because you have the Date in American format in line[i] and UK format in the FormatString.

11/20/2011
M / d/yyyy

I'm guessing you might need to change the FormatString to:

"M/d/yyyy h:mm"

You can't set CURRENT_TIMESTAMP as default value with DATETIME.

But you can do it with TIMESTAMP.

See the difference here.

Words from this blog

The DEFAULT value clause in a data type specification indicates a default value for a column. With one exception, the default value must be a constant; it cannot be a function or an expression.

This means, for example, that you cannot set the default for a date column to be the value of a function such as NOW() or CURRENT_DATE.

The exception is that you can specify CURRENT_TIMESTAMP as the default for a TIMESTAMP column.

An updated solution using numpy v1.13+ requires specifying the axis in np.unique if using multiple columns, otherwise the array is implicitly flattened.

import numpy as np

np.unique(df[['col1', 'col2']], axis=0)

This change was introduced Nov 2016: https://github.com/numpy/numpy/commit/1f764dbff7c496d6636dc0430f083ada9ff4e4be

You can use regular expression like this.

/^[(]+\ ++\d{2}[)]+[^0]+\d{9}/

var description=document.getElementsByTagName('h4')[0].innerHTML;
var link = document.createElement('meta');
  
link.setAttribute('name', 'description');
  
link.content = description;
  
document.getElementsByTagName('head')[0].appendChild(link);
var htwo=document.getElementsByTagName('h2');
var hthree=document.getElementsByTagName('h3');
var ls=[];
for(var i=0;i<hthree.length;i++){ls.push(htwo[i].innerHTML);}

for(var i=0;i<hthree.length;i++){ls.push(hthree[i].innerHTML);}

var keyword=ls.toString()
;
var keyw = document.createElement('meta');
  
keyw.setAttribute('name', 'keywords');
  
keyw.content = keyword;
  
document.getElementsByTagName('head')[0].appendChild(keyw);

in my case, I write this code and all my meta tags are working perfectly but we can not see the actual meta tag it will be hidden somewhere.

I can't get to your google docs file at the moment but there are some issues with your code that I will try to address while answering

Sub stituterangersNEW()
Dim t As Range
Dim x As Range
Dim dify As Boolean
Dim difx As Boolean
Dim time2 As Date
Dim time1 As Date

    'You said time1 doesn't change, so I left it in a singe cell.
    'If that is not correct, you will have to play with this some more.
    time1 = Range("A6").Value

    'Looping through each of our output cells.
    For Each t In Range("B7:E9") 'Change these to match your real ranges.

        'Looping through each departure date/time.
        '(Only one row in your example. This can be adjusted if needed.)
        For Each x In Range("B2:E2") 'Change these to match your real ranges.
            'Check to see if our dep time corresponds to
            'the matching column in our output
            If t.Column = x.Column Then
                'If it does, then check to see what our time value is
                If x > 0 Then
                    time2 = x.Value
                    'Apply the change to the output cell.
                    t.Value = time1 - time2
                    'Exit out of this loop and move to the next output cell.
                    Exit For
                End If
            End If
            'If the columns don't match, or the x value is not a time
            'then we'll move to the next dep time (x)
        Next x
    Next t

End Sub

EDIT

I changed you worksheet to play with (see above for the new Sub). This probably does not suite your needs directly, but hopefully it will demonstrate the conept behind what I think you want to do. Please keep in mind that this code does not follow all the coding best preactices I would recommend (e.g. validating the time is actually a TIME and not some random other data type).

     A                      B                   C                   D                  E
1    LOAD_NUMBER            1                   2                   3                  4
2    DEPARTURE_TIME_DATE    11/12/2011 19:30    11/12/2011 19:30    11/12/2011 19:30    11/12/2011 20:00                
4    Dry_Refrig 7585.1  0   10099.8 16700
6    1/4/2012 19:30

Using the sub I got this output:

    A           B             C             D             E
7   Friday      1272:00:00    1272:00:00    1272:00:00    1271:30:00
8   Saturday    1272:00:00    1272:00:00    1272:00:00    1271:30:00
9   Thursday    1272:00:00    1272:00:00    1272:00:00    1271:30:00

In my case, I had opened a query from data context, like

    Dim stores = DataContext.Stores _
        .Where(Function(d) filter.Contains(d.code)) _

... and then subsequently queried the same...

    Dim stores = DataContext.Stores _
        .Where(Function(d) filter.Contains(d.code)).ToList

Adding the .ToList to the first resolved my issue. I think it makes sense to wrap this in a property like:

Public ReadOnly Property Stores As List(Of Store)
    Get
        If _stores Is Nothing Then
            _stores = DataContext.Stores _
                .Where(Function(d) Filters.Contains(d.code)).ToList
        End If
        Return _stores
    End Get
End Property

Where _stores is a private variable, and Filters is also a readonly property that reads from AppSettings.

There's also a cute little trick that lets you specify a single host on the command line (or multiple hosts, I guess), without an intermediary inventory:

ansible-playbook -i "imac1-local," user.yml

Note the comma (,) at the end; this signals that it's a list, not a file.

Now, this won't protect you if you accidentally pass a real inventory file in, so it may not be a good solution to this specific problem. But it's a handy trick to know!

You can use boolean indexing:

df = pd.DataFrame({'Sales':[10,20,30,40,50], 'A':[3,4,7,6,1]})
print (df)
   A  Sales
0  3     10
1  4     20
2  7     30
3  6     40
4  1     50

s = 30

df1 = df[df['Sales'] >= s]
print (df1)
   A  Sales
2  7     30
3  6     40
4  1     50

df2 = df[df['Sales'] < s]
print (df2)
   A  Sales
0  3     10
1  4     20

It's also possible to invert mask by ~:

mask = df['Sales'] >= s
df1 = df[mask]
df2 = df[~mask]
print (df1)
   A  Sales
2  7     30
3  6     40
4  1     50

print (df2)
   A  Sales
0  3     10
1  4     20

print (mask)
0    False
1    False
2     True
3     True
4     True
Name: Sales, dtype: bool

print (~mask)
0     True
1     True
2    False
3    False
4    False
Name: Sales, dtype: bool

In the app function you have incorrectly spelled the word setpersonSate, missing the letter t, thus it should be setpersonState.

Error:

const app = props => { 
    const [personState, setPersonSate] = useState({....

Solution:

const app = props => { 
        const [personState, setPersonState] = useState({....

Try this:

;WITH CTE
AS
(
    SELECT DISTINCT
        M1.Product_ID Group_ID,
        M1.Product_ID
    FROM matches M1
        LEFT JOIN matches M2
            ON M1.Product_Id = M2.matching_Product_Id
    WHERE M2.matching_Product_Id IS NULL
    UNION ALL
    SELECT
        C.Group_ID,
        M.matching_Product_Id
    FROM CTE C
        JOIN matches M
            ON C.Product_ID = M.Product_ID
)
SELECT * FROM CTE ORDER BY Group_ID

You can use OPTION(MAXRECURSION n) to control recursion depth.

just hoping to be helpful to someone as old problems seem to come back every now and again and I always find good tips here.

My problem was to list in a text file all the names of the "*.txt" files in a certain directory without path and without extension from a Datastage 7.5 sequence.

The solution we used is:

ls /home/user/new/*.txt | xargs -n 1 basename | cut -d '.' -f1 > name_list.txt

To respond to something Mehrdad said:

However, there might be cases where you still need arrays. When interfacing with low level code (i.e. assembly) or old libraries that require arrays, you might not be able to use vectors.

Not true at all. Vectors degrade nicely into arrays/pointers if you use:

vector<double> vector;
vector.push_back(42);

double *array = &(*vector.begin());

// pass the array to whatever low-level code you have

This works for all major STL implementations. In the next standard, it will be required to work (even though it does just fine today).

Add the column and update all rows in the DataTable, for example:

DataTable tbl = new DataTable();
tbl.Columns.Add(new DataColumn("ID", typeof(Int32)));
tbl.Columns.Add(new DataColumn("Name", typeof(string)));
for (Int32 i = 1; i <= 10; i++) {
    DataRow row = tbl.NewRow();
    row["ID"] = i;
    row["Name"] = i + ". row";
    tbl.Rows.Add(row);
}
DataColumn newCol = new DataColumn("NewColumn", typeof(string));
newCol.AllowDBNull = true;
tbl.Columns.Add(newCol);
foreach (DataRow row in tbl.Rows) {
    row["NewColumn"] = "You DropDownList value";
}
//if you don't want to allow null-values'
newCol.AllowDBNull = false;

See this post of mine about "Error creating window handle" and how it relates to USER Objects and the Desktop Heap. I provide some solutions.

unique_ptr is the light-weight smart pointer of choice if you just have a dynamic object somewhere for which one consumer has sole (hence "unique") responsibility -- maybe a wrapper class that needs to maintain some dynamically allocated object. unique_ptr has very little overhead. It is not copyable, but movable. Its type is template <typename D, typename Deleter> class unique_ptr;, so it depends on two template parameters.

unique_ptr is also what auto_ptr wanted to be in the old C++ but couldn't because of that language's limitations.

shared_ptr on the other hand is a very different animal. The obvious difference is that you can have many consumers sharing responsibility for a dynamic object (hence "shared"), and the object will only be destroyed when all shared pointers have gone away. Additionally you can have observing weak pointers which will intelligently be informed if the shared pointer they're following has disappeared.

Internally, shared_ptr has a lot more going on: There is a reference count, which is updated atomically to allow the use in concurrent code. Also, there's plenty of allocation going on, one for an internal bookkeeping "reference control block", and another (often) for the actual member object.

But there's another big difference: The shared pointers type is always template <typename T> class shared_ptr;, and this is despite the fact that you can initialize it with custom deleters and with custom allocators. The deleter and allocator are tracked using type erasure and virtual function dispatch, which adds to the internal weight of the class, but has the enormous advantage that different sorts of shared pointers of type T are all compatible, no matter the deletion and allocation details. Thus they truly express the concept of "shared responsibility for T" without burdening the consumer with the details!

Both shared_ptr and unique_ptr are designed to be passed by value (with the obvious movability requirement for the unique pointer). Neither should make you worried about the overhead, since their power is truly astounding, but if you have a choice, prefer unique_ptr, and only use shared_ptr if you really need shared responsibility.

1. Show where memory is allocated sudo du -x -h / | sort -h | tail -40
2. Delete from either your /tmp or /home/user_name/.cache folder if these are taking up a lot of memory. You can do this by running sudo rm -R /path/to/folder

Step 2 outlines fairly common folders to delete from (/tmp and /home/user_name/.cache). If you get back other results when running the first command showing you have lots of memory being used elsewhere, I advise being a bit more cautious when deleting from those locations.

Export should be specific about which version of GCC/G++ to use, because if user had multiple compiler version, it would not compile successfully.

 export CC=path_of_gcc/gcc-version
 export CXX=path_of_g++/g++-version
 cmake  path_of_project_contain_CMakeList.txt
 make 

In case project use C++11 this can be handled by using -std=C++-11 flag in CMakeList.txt

ES6 introduce template strings for concatenation. Template Strings use back-ticks (``) rather than the single or double quotes we're used to with regular strings. A template string could thus be written as follows:

// Simple string substitution
let name = "Brendan";
console.log(`Yo, ${name}!`);

// => "Yo, Brendan!"

var a = 10;
var b = 10;
console.log(`JavaScript first appeared ${a+b} years ago. Crazy!`);

//=> JavaScript first appeared 20 years ago. Crazy!

Try this:

String status = "The status of my combobox is " + comboBoxTest.text;

Null Coalescing operator performs just two tasks: it checks whether the variable is set and whether it is null. Have a look at the following example:

<?php
# case 1:
$greeting = 'Hola';
echo $greeting ?? 'Hi There'; # outputs: 'Hola'

# case 2:
$greeting = null;
echo $greeting ?? 'Hi There'; # outputs: 'Hi There'

# case 3:
unset($greeting);
echo $greeting ?? 'Hi There'; # outputs: 'Hi There'

The above code example states that Null Coalescing operator treats a non-existing variable and a variable which is set to NULL in the same way.

Null Coalescing operator is an improvement over the ternary operator. Have a look at the following code snippet comparing the two:

<?php /* example: checking for the $_POST field that goes by the name of 'fullname'*/
# in ternary operator
echo "Welcome ", (isset($_POST['fullname']) && !is_null($_POST['fullname']) ? $_POST['fullname'] : 'Mr. Whosoever.'); # outputs: Welcome Mr. Whosoever.
# in null coalecing operator
echo "Welcome ", ($_POST['fullname'] ?? 'Mr. Whosoever.'); # outputs: Welcome Mr. Whosoever.

So, the difference between the two is that Null Coalescing operator operator is designed to handle undefined variables better than the ternary operator. Whereas, the ternary operator is a shorthand for if-else.

Null Coalescing operator is not meant to replace ternary operator, but in some use cases like in the above example, it allows you to write clean code with less hassle.

Note that your conversion function should ideally be returning a const char *.

If you can afford to put your enums in their separate header files, you could perhaps do something like this with macros (oh, this will be ugly):

#include "enum_def.h"
#include "colour.h"
#include "enum_conv.h"
#include "colour.h"

Where enum_def.h has:

#undef ENUM_START
#undef ENUM_ADD
#undef ENUM_END
#define ENUM_START(NAME) enum NAME {
#define ENUM_ADD(NAME, VALUE) NAME = VALUE,
#define ENUM_END };

And enum_conv.h has:

#undef ENUM_START
#undef ENUM_ADD
#undef ENUM_END
#define ENUM_START(NAME) const char *##NAME##_to_string(NAME val) { switch (val) {
#define ENUM_ADD(NAME, VALUE) case NAME: return #NAME;
#define ENUM_END default: return "Invalid value"; } }

And finally, colour.h has:

ENUM_START(colour)
ENUM_ADD(red,   0xff0000)
ENUM_ADD(green, 0x00ff00)
ENUM_ADD(blue,  0x0000ff)
ENUM_END

And you can use the conversion function as:

printf("%s", colour_to_string(colour::red));

This is ugly, but it's the only way (at the preprocessor level) that lets you define your enum just in a single place in your code. Your code is therefore not prone to errors due to modifications to the enum. Your enum definition and the conversion function will always be in sync. However, I repeat, this is ugly :)

If nothing works, just create the adapter instance again with the new set of results or the updated set of results. Then you can see the new view.

XYZAdapter adbXzy = new XYZAdapter(context, 0, listData);
xyzListView.setAdapter(adbXzy);

adbXzy.notifyDataSetChanged();

You need to include the reference to the assembly System.Web.Mvc in you project.

you may not have the System.Web.Mvc in your C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework.NETFramework\v4.0

So you need to add it and then to include it as reference to your projrect

How about using a List instead? For example, ArrayList<integer>

While the answers explaining the exact differences are fine, I want to show how the relational algebra is transformed to SQL and what the actual value of the 3 concepts is.

The key concept in your question is the idea of a join. To understand a join you need to understand a Cartesian Product (the example is based on SQL where the equivalent is called a cross join as onedaywhen points out);

This isn't very useful in practice. Consider this example.

Product(PName, Price)
====================
Laptop,   1500
Car,      20000
Airplane, 3000000


Component(PName, CName, Cost)
=============================
Laptop, CPU,    500
Laptop, hdd,    300
Laptop, case,   700
Car,    wheels, 1000

The Cartesian product Product x Component will be - bellow or sql fiddle. You can see there are 12 rows = 3 x 4. Obviously, rows like "Laptop" with "wheels" have no meaning, this is why in practice the Cartesian product is rarely used.

|    PNAME |   PRICE |  CNAME | COST |
--------------------------------------
|   Laptop |    1500 |    CPU |  500 |
|   Laptop |    1500 |    hdd |  300 |
|   Laptop |    1500 |   case |  700 |
|   Laptop |    1500 | wheels | 1000 |
|      Car |   20000 |    CPU |  500 |
|      Car |   20000 |    hdd |  300 |
|      Car |   20000 |   case |  700 |
|      Car |   20000 | wheels | 1000 |
| Airplane | 3000000 |    CPU |  500 |
| Airplane | 3000000 |    hdd |  300 |
| Airplane | 3000000 |   case |  700 |
| Airplane | 3000000 | wheels | 1000 |

JOINs are here to add more value to these products. What we really want is to "join" the product with its associated components, because each component belongs to a product. The way to do this is with a join:

Product JOIN Component ON Pname

The associated SQL query would be like this (you can play with all the examples here)

SELECT *
FROM Product
JOIN Component
  ON Product.Pname = Component.Pname

and the result:

|  PNAME | PRICE |  CNAME | COST |
----------------------------------
| Laptop |  1500 |    CPU |  500 |
| Laptop |  1500 |    hdd |  300 |
| Laptop |  1500 |   case |  700 |
|    Car | 20000 | wheels | 1000 |

Notice that the result has only 4 rows, because the Laptop has 3 components, the Car has 1 and the Airplane none. This is much more useful.

Getting back to your questions, all the joins you ask about are variations of the JOIN I just showed:

Natural Join = the join (the ON clause) is made on all columns with the same name; it removes duplicate columns from the result, as opposed to all other joins; most DBMS (database systems created by various vendors such as Microsoft's SQL Server, Oracle's MySQL etc. ) don't even bother supporting this, it is just bad practice (or purposely chose not to implement it). Imagine that a developer comes and changes the name of the second column in Product from Price to Cost. Then all the natural joins would be done on PName AND on Cost, resulting in 0 rows since no numbers match.

Theta Join = this is the general join everybody uses because it allows you to specify the condition (the ON clause in SQL). You can join on pretty much any condition you like, for example on Products that have the first 2 letters similar, or that have a different price. In practice, this is rarely the case - in 95% of the cases you will join on an equality condition, which leads us to:

Equi Join = the most common one used in practice. The example above is an equi join. Databases are optimized for this type of joins! The oposite of an equi join is a non-equi join, i.e. when you join on a condition other than "=". Databases are not optimized for this! Both of them are subsets of the general theta join. The natural join is also a theta join but the condition (the theta) is implicit.

Source of information: university + certified SQL Server developer + recently completed the MOO "Introduction to databases" from Stanford so I dare say I have relational algebra fresh in mind.

With Java 11 you won't have to go through this rigmarole anymore!

Instead, you can do this:

> java MyApp.java

You don't have to compile beforehand, as it's all done in one step.

You can get the Java 11 JDK here: JDK 11 GA Release

In build.gradle change minSdkVersion 17 or later.

This is an issue of selector specificity. (The selector .selected is less specific than ul.nav li.)

To fix, use as much specificity in the overriding rule as in the original:

ul.nav li {
 background-color:blue;
}
ul.nav li.selected {
 background-color:red;
}

You might also consider nixing the ul, unless there will be other .navs. So:

.nav li {
 background-color:blue;
}
.nav li.selected {
 background-color:red;
}

That's a bit cleaner, less typing, and fewer bits.

It's pretty simple to do this without jQuery these days.

Without jQuery:

Just select the elements and use the .forEach() method to iterate over them:

const elements = document.querySelectorAll('.testimonial');
Array.from(elements).forEach((element, index) => {
  // conditional logic here.. access element
});

In older browsers:

var testimonials = document.querySelectorAll('.testimonial');
Array.prototype.forEach.call(testimonials, function(element, index) {
  // conditional logic here.. access element
});

I can think of a quick code like this.

Since all USB ports can be accessed via /dev/bus/usb/< bus >/< device >

For the ID generated, even if you unplug the device and reattach it [ could be some other port ]. It will be the same.

import re
import subprocess
device_re = re.compile("Bus\s+(?P<bus>\d+)\s+Device\s+(?P<device>\d+).+ID\s(?P<id>\w+:\w+)\s(?P<tag>.+)$", re.I)
df = subprocess.check_output("lsusb")
devices = []
for i in df.split('\n'):
    if i:
        info = device_re.match(i)
        if info:
            dinfo = info.groupdict()
            dinfo['device'] = '/dev/bus/usb/%s/%s' % (dinfo.pop('bus'), dinfo.pop('device'))
            devices.append(dinfo)
print devices

Sample output here will be:

[
{'device': '/dev/bus/usb/001/009', 'tag': 'Apple, Inc. Optical USB Mouse [Mitsumi]', 'id': '05ac:0304'},
{'device': '/dev/bus/usb/001/001', 'tag': 'Linux Foundation 2.0 root hub', 'id': '1d6b:0002'},
{'device': '/dev/bus/usb/001/002', 'tag': 'Intel Corp. Integrated Rate Matching Hub', 'id': '8087:0020'},
{'device': '/dev/bus/usb/001/004', 'tag': 'Microdia ', 'id': '0c45:641d'}
]

Code Updated for Python 3

import re
import subprocess
device_re = re.compile(b"Bus\s+(?P<bus>\d+)\s+Device\s+(?P<device>\d+).+ID\s(?P<id>\w+:\w+)\s(?P<tag>.+)$", re.I)
df = subprocess.check_output("lsusb")
devices = []
for i in df.split(b'\n'):
    if i:
        info = device_re.match(i)
        if info:
            dinfo = info.groupdict()
            dinfo['device'] = '/dev/bus/usb/%s/%s' % (dinfo.pop('bus'), dinfo.pop('device'))
            devices.append(dinfo)
            
print(devices)

listView.setOnItemClickListener(new OnItemClickListener() {

    public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
        Object o = prestListView.getItemAtPosition(position);

        Toast.makeText(getBaseContext(),str.getTitle(),Toast.LENGTH_SHORT).show();

I would fire up Visual Studio, create a web project (or console app - doesn't matter).

For .Net Standard:

1. I would right-click on the project and pick "Add Service Reference" from the Add context menu.
2. I would click on Advanced, then click on Add Service Reference.
3. I would get the complete file path of the wsdl and paste into the address bar. Then fire the Arrow (go button).
4. If there is an error trying to load the file, then there must be a broken and unresolved url the file needs to resolve as shown below: Refer to this answer for information on how to fix: Stackoverflow answer to: Unable to create service reference for wsdl file

If there is no error, you should simply set the NameSpace you want to use to access the service and it'll be generated for you.

For .Net Core

1. I would right click on the project and pick Connected Service from the Add context menu.
2. I would select Microsoft WCF Web Service Reference Provider from the list.
3. I would press browse and select the wsdl file straight away, Set the namespace and I am good to go. Refer to the error fix url above if you encounter any error.

Any of the methods above will generate a simple, very basic WCF client for you to use. You should find a "YourservicenameClient" class in the generated code.

For reference purpose, the generated cs file can be found in your Obj/debug(or release)/XsdGeneratedCode and you can still find the dlls in the TempPE folder.

The created Service(s) should have methods for each of the defined methods on the WSDL contract.

Instantiate the client and call the methods you want to call - that's all there is!

YourServiceClient client = new YourServiceClient();
client.SayHello("World!");

If you need to specify the remote URL (not using the one created by default), you can easily do this in the constructor of the proxy client:

YourServiceClient client = new YourServiceClient("configName", "remoteURL");

where configName is the name of the endpoint to use (you will use all the settings except the URL), and the remoteURL is a string representing the URL to connect to (instead of the one contained in the config).

</script> has to be broken up because otherwise it would end the enclosing <script></script> block too early. Really it should be split between the < and the /, because a script block is supposed (according to SGML) to be terminated by any end-tag open (ETAGO) sequence (i.e. </):

Although the STYLE and SCRIPT elements use CDATA for their data model, for these elements, CDATA must be handled differently by user agents. Markup and entities must be treated as raw text and passed to the application as is. The first occurrence of the character sequence "</" (end-tag open delimiter) is treated as terminating the end of the element's content. In valid documents, this would be the end tag for the element.

However in practice browsers only end parsing a CDATA script block on an actual </script> close-tag.

In XHTML there is no such special handling for script blocks, so any < (or &) character inside them must be &escaped; like in any other element. However then browsers that are parsing XHTML as old-school HTML will get confused. There are workarounds involving CDATA blocks, but it's easiest simply to avoid using these characters unescaped. A better way of writing a script element from script that works on either type of parser would be:

<script type="text/javascript">
    document.write('\x3Cscript type="text/javascript" src="foo.js">\x3C/script>');
</script>

Short and simple differences between Tcp and Udp protocol:

1) Tcp - Transmission control protocol and Udp - User datagram protocol.

2) Tcp is reliable protocol, Where as Udp is a unreliable protocol.

3) Tcp is a stream oriented, where as Udp is a message oriented protocol.

4) Tcp is a slower than Udp.

If you're wondering about functionality, then jQuery's .html() performs the same intended functionality as .innerHTML, but it also performs checks for cross-browser compatibility.

For this reason, you can always use jQuery's .html() instead of .innerHTML where possible.

For my scenario, my JS was in a separate file, so using a ClientID response output wasn't conducive. Surprisingly, the solution was as simple as adding a CssClass to the RadioButtonList, which I found out on DevCurry

Just incase that solution disappears, add a class to your radio button list

<asp:RadioButtonList id="rbl" runat="server" class="tbl">...

As the article points out, when the radio button list is rendered, the class "tbl" is appended to the surrounding table

<table id="rbl" class="tbl" border="0">
<tr>...

Now because of the CSS class that has been appended, you can just refer to input:radio items within your table, based on the css class selector

$(function () {
            var $radBtn = $("table.tbl input:radio");
            $radBtn.click(function () {
                var $radChecked = $(':radio:checked');
                alert($radChecked.val());
            });
        });

Again, this avoids using the "ClientID" mentioned above which I found messy for my scenario. Hope this helps!

Never mind, I found it in the docs:

-g/--globoff
              This  option  switches  off  the "URL globbing parser". When you set this option, you can
              specify URLs that contain the letters {}[] without having them being interpreted by  curl
              itself.  Note  that  these  letters  are not normal legal URL contents but they should be
              encoded according to the URI standard.

Better option is to use :

{{(100*score/questionCounter) || 0 | number:0}}

It sets default value of equation to 0 in the case when values are not initialized.

String.prototype.includes is, as you write, not supported in Internet Explorer (or Opera).

Instead you can use String.prototype.indexOf. #indexOf returns the index of the first character of the substring if it is in the string, otherwise it returns -1. (Much like the Array equivalent)

var myString = 'this is my string';
myString.indexOf('string');
// -> 11

myString.indexOf('hello');
// -> -1

MDN has a polyfill for includes using indexOf: https://developer.mozilla.org/en/docs/Web/JavaScript/Reference/Global_Objects/String/includes#Polyfill

EDIT: Opera supports includes as of version 28.

EDIT 2: Current versions of Edge supports the method. (as of 2019)

You could perhaps use something like

interface EnumWithId {
    public int getId();

}


enum Foo implements EnumWithId {

   ...
}

That would reduce the need for reflection in your utility class.

This is not possible with the magic methods, however you can achieve this using DQL (Doctrine Query Language). In your example, assuming you have entity named Orders with Product property, just go ahead and do the following:

$dql_query = $em->createQuery("
    SELECT o FROM AcmeCodeBundle:Orders o
    WHERE 
      o.OrderEmail = '[email protected]' AND
      o.Product LIKE 'My Products%'
");
$orders = $dql_query->getResult();

Should do exactly what you need.

Another way is to tell the marshaller to always use a certain prefix

marshaller.setProperty("com.sun.xml.bind.namespacePrefixMapper", new NamespacePrefixMapper() {
             @Override
            public String getPreferredPrefix(String arg0, String arg1, boolean arg2) {
                return "ns1";
            }
        });'

Try the packaged pecl version instead (the advantage of the packaged installs is that they're easier to upgrade):

apt-get install php5-dev
pecl install pdo
pecl install pdo_pgsql

or, if you just need a driver for PHP, but that it doesn't have to be the PDO one:

apt-get install php5-pgsql

Otherwise, that message most likely means you need to install a more recent libpq package. You can check which version you have by running:

dpkg -s libpq-dev

I had the same problem It happens because files can't contain special characters like ":", "?", ">" and etc. You should replace these files by using replace() function:

filename = filename.replace("special character to replace", "-")

I had faced this issue recently, after trying different ways to sign in like enable V1 Or V2, signed in by changing alias name and last come to know that I am using wrong key store file

for me it's working it's not creating another Intents and on same the Intents new data loaded.

    overridePendingTransition(0, 0);
    finish();
    overridePendingTransition(0, 0);
    startActivity(getIntent());
    overridePendingTransition(0, 0);

def search(myDict, lookup):
    a=[]
    for key, value in myDict.items():
        for v in value:
            if lookup in v:
                 a.append(key)
    a=list(set(a))
    return a

if the research involves more keys maybe you should create a list with all the keys

Let's see how your algorithm works:

an array of unique values:

[1, 2, 3]

check 1 == 1. yes, there is duplicate, assigning duplicate to true.
check 1 == 2. no, doing nothing.
check 1 == 3. no, doing nothing.
check 2 == 1. no, doing nothing.
check 2 == 2. yes, there is duplicate, assigning duplicate to true.
check 2 == 3. no, doing nothing.
check 3 == 1. no, doing nothing.
check 3 == 2. no, doing nothing.
check 3 == 3. yes, there is duplicate, assigning duplicate to true.

a better algorithm:

for (j=0;j<zipcodeList.length;j++) {
    for (k=j+1;k<zipcodeList.length;k++) {
        if (zipcodeList[k]==zipcodeList[j]){ // or use .equals()
            return true;
        }
    }
}
return false;

This error means that the SELECT store_key FROM store query has returned two or more rows in the SERVER1 database. If you would like to update all customers, use a join instead of a scalar = operator. You need a condition to "connect" customers to store items in order to do that.

If you wish to update all customer_ids to the same store_key, you need to supply a WHERE clause to the remotely executed SELECT so that the query returns a single row.

To hide an element, use:

display: none;
visibility: hidden;

To show an element, use:

display: block;
visibility: visible;

The difference is:

Visibility handles the visibility of the tag, the display handles space it occupies on the page.

If you set the visibility and do not change the display, even if the tags are not seen, it still occupies space.

Just found this one (don't know it, not tested, check yourself)

Ron Cemer Java OCR

As you only need this for curiosity you could look into the source of this applet.

It does OCR of handwritten characters with a neural network

Java OCR: Handwriting Recognition

You might be needing a cleanup:

git gc --prune=now

or you might be needing a prune:

git remote prune public

prune

Deletes all stale tracking branches under <name>. These stale branches have already been removed from the remote repository referenced by <name>, but are still locally available in "remotes/<name>".

With --dry-run option, report what branches will be pruned, but do no actually prune them.

However, it appears these should have been cleaned up earlier with

git remote rm public 

rm

Remove the remote named <name>. All remote tracking branches and configuration settings for the remote are removed.

So it might be you hand-edited your config file and this did not occur, or you have privilege problems.

Maybe run that again and see what happens.

Advice Context

If you take a look in the revision logs, you'll note I suggested more "correct" techniques, which for whatever reason didn't want to work on their repository.

I suspected the OP had done something that left their tree in an inconsistent state that caused it to behave a bit strangely, and git gc was required to fix up the left behind cruft.

Usually git branch -rd origin/badbranch is sufficient for nuking a local tracking branch , or git push origin :badbranch for nuking a remote branch, and usually you will never need to call git gc

^https?://

You might have to escape the forward slashes though, depending on context.

I would suggest using modernizr and using its media query features.

if (Modernizr.touch){
   // bind to touchstart, touchmove, etc and watch `event.streamId`
} else {
   // bind to normal click, mousemove, etc
}

However, using CSS, there are pseudo class like, for example in Firefox. You can use :-moz-system-metric(touch-enabled). But these features are not available for every browser.

For Apple devices, you can simple use:

if(window.TouchEvent) {
   //.....
}

Especially for Ipad:

if(window.Touch) {
    //....
}

But, these do not work on Android.

Modernizr gives feature detection abilities, and detecting features is a good way to code, rather than coding on basis of browsers.

Styling Touch Elements

Modernizer adds classes to the HTML tag for this exact purpose. In this case, touch and no-touch so you can style your touch related aspects by prefixing your selectors with .touch. e.g. .touch .your-container. ^{Credits: Ben Swinburne}

Update: a better idea, set the "AppendDataBoundItems" property to true, then declare the "Choose item" declaratively. The databinding operation will add to the statically declared item.

<asp:DropDownList ID="ddl" runat="server" AppendDataBoundItems="true">
    <asp:ListItem Value="0" Text="Please choose..."></asp:ListItem>
</asp:DropDownList>

Go to File Menu -> Import Sessions...

Select the "HTTPArchive" Option

Browse to your HAR file

The HAR file will open and replay on the fiddler window.

Programmatic ICMP ping is complicated due to the elevated privileges required to send raw ICMP packets, and calling ping binary is ugly. For server monitoring, you can achieve the same result using a technique called TCP ping:

# pip3 install tcping
>>> from tcping import Ping
# Ping(host, port, timeout)
>>> ping = Ping('212.69.63.54', 22, 60)

Internally, this simply establishes a TCP connection to the target server and drops it immediately, measuring time elapsed. This particular implementation is a bit limited in that it doesn't handle closed ports but for your own servers it works pretty well.

THE FINAL ANSWER FOR THOSE WHO USES ANGULAR 6:

Add the below command in your *.service.ts file"

import { map } from "rxjs/operators";

**********************************************Example**Below**************************************
getPosts(){
this.http.get('http://jsonplaceholder.typicode.com/posts')
.pipe(map(res => res.json()));
}
}

I am using windows 10;

Though this question is meanwhile closed, I believe it is worth mentioning how this atrocity came into existence. In a way, you may blame the C# spec, which states that a double must have a precision of 15 or 16 digits (the result of IEEE-754). A bit further on (section 4.1.6) it's stated that implementations are allowed to use higher precision. Mind you: higher, not lower. They are even allowed to deviate from IEEE-754: expressions of the type x * y / z where x * y would yield +/-INF but would be in a valid range after dividing, do not have to result in an error. This feature makes it easier for compilers to use higher precision in architectures where that'd yield better performance.

But I promised a "reason". Here's a quote (you requested a resource in one of your recent comments) from the Shared Source CLI, in clr/src/vm/comnumber.cpp:

"In order to give numbers that are both friendly to display and round-trippable, we parse the number using 15 digits and then determine if it round trips to the same value. If it does, we convert that NUMBER to a string, otherwise we reparse using 17 digits and display that."

In other words: MS's CLI Development Team decided to be both round-trippable and show pretty values that aren't such a pain to read. Good or bad? I'd wish for an opt-in or opt-out.

The trick it does to find out this round-trippability of any given number? Conversion to a generic NUMBER structure (which has separate fields for the properties of a double) and back, and then compare whether the result is different. If it is different, the exact value is used (as in your middle value with 6.9 - i) if it is the same, the "pretty value" is used.

As you already remarked in a comment to Andyp, 6.90...00 is bitwise equal to 6.89...9467. And now you know why 0.0...8818 is used: it is bitwise different from 0.0.

This 15 digits barrier is hard-coded and can only be changed by recompiling the CLI, by using Mono or by calling Microsoft and convincing them to add an option to print full "precision" (it is not really precision, but by the lack of a better word). It's probably easier to just calculate the 52 bits precision yourself or use the library mentioned earlier.

EDIT: if you like to experiment yourself with IEE-754 floating points, consider this online tool, which shows you all relevant parts of a floating point.

TextView rowTextView = (TextView)getLayoutInflater().inflate(R.layout.yourTextView, null);
        rowTextView.setText(text);
        layout.addView(rowTextView);

This is how I'm using this:

 private List<Tag> tags = new ArrayList<>();


if(tags.isEmpty()){
        Gson gson = new Gson();
        Type listType = new TypeToken<List<Tag>>() {
        }.getType();
        tags = gson.fromJson(tour.getTagsJSONArray(), listType);
    }



if (flowLayout != null) {
        if(!tags.isEmpty()) {
            Log.e(TAG, "setTags: "+ flowLayout.getChildCount() );
            flowLayout.removeAllViews();
            for (Tag tag : tags) {
                FlowLayout.LayoutParams lparams = new FlowLayout.LayoutParams(FlowLayout.LayoutParams.WRAP_CONTENT, FlowLayout.LayoutParams.WRAP_CONTENT);
                lparams.setMargins(PixelUtil.dpToPx(this, 0), PixelUtil.dpToPx(this, 5), PixelUtil.dpToPx(this, 10), PixelUtil.dpToPx(this, 5));// llp.setMargins(left, top, right, bottom);
                TextView rowTextView = (TextView) getLayoutInflater().inflate(R.layout.tag, null);
                rowTextView.setText(tag.getLabel());
                rowTextView.setLayoutParams(lparams);
                flowLayout.addView(rowTextView);
            }
        }
        Log.e(TAG, "setTags: after "+ flowLayout.getChildCount() );
    }

And this is my custom TextView named tag:

<?xml version="1.0" encoding="utf-8"?><TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"    
android:textSize="10dp"
android:textAllCaps="true"
fontPath="@string/font_light"
android:background="@drawable/tag_shape"
android:paddingLeft="11dp"
android:paddingTop="6dp"
android:paddingRight="11dp"
android:paddingBottom="6dp">

this is my tag_shape:

<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<solid android:color="#f2f2f2" />
<corners android:radius="15dp" />
</shape>

In other place I'm adding textviews with language names from dialog with listview:

One notable difference is that if you pass a .c file to gcc it will compile as C.

The default behavior of g++ is to treat .c files as C++ (unless -x c is specified).

I had the same problem cause i had no public keys, so i did:

heroku keys:clear
heroku keys:add

That will generate a public key and then it works well

Try:

if not "asdf" == "fdas" echo asdf

That works for me on Windows XP (I get the same error as you for the code you posted).

According to the doc about Run tests by node ids

since you have all node ids in foo.txt, just run

pytest `cat foo.txt | tr '\n' ' '`

this is same with below command (with file content in the question)

pytest tests_directory/foo.py::test_001 tests_directory/bar.py::test_some_other_test

All of the current answers are addressing the symptom (shared memory pool exhaustion), and not the problem, which is likely not using bind variables in your sql \ JDBC queries, even when it does not seem necessary to do so. Passing queries without bind variables causes Oracle to "hard parse" the query each time, determining its plan of execution, etc.

https://asktom.oracle.com/pls/asktom/f?p=100:11:0::::p11_question_id:528893984337

Some snippets from the above link:

"Java supports bind variables, your developers must start using prepared statements and bind inputs into it. If you want your system to ultimately scale beyond say about 3 or 4 users -- you will do this right now (fix the code). It is not something to think about, it is something you MUST do. A side effect of this - your shared pool problems will pretty much disappear. That is the root cause. "

"The way the Oracle shared pool (a very important shared memory data structure) operates is predicated on developers using bind variables."

" Bind variables are SO MASSIVELY important -- I cannot in any way shape or form OVERSTATE their importance. "

In case of PUT or POST Request. if you receive statusCode 405 or method not allowed. Try this implementation with "request" library, and add mentioned properties.
followAllRedirects: true,
followOriginalHttpMethod: true

       const options = {
           headers: {
               Authorization: TOKEN,
               'Content-Type': 'application/json',
               'Accept': 'application/json'
           },
           url: `https://${url}`,
           json: true,
           body: payload,
           followAllRedirects: true,
           followOriginalHttpMethod: true
       }

       console.log('DEBUG: API call', JSON.stringify(options));
       request(options, function (error, response, body) {
       if (!error) {
        console.log(response);
        }
     });
}

I want to add a little bit of improvement from an almost excellent answer from user @thyago stall above. In Python, we can do one line swapping. The selection_sort below also has been fixed by just swapping the current element with the minimum element at the right side.

In insertion sort we will run the outer loop from the second element and do an inner loop on the left side of the current element, shifting the smaller elements to the left.

def insertion_sort(arr):
    i = 1
    while i < len(arr):
        for j in range(i):
            if arr[i] < arr[j]:
                arr[i], arr[j] = arr[j], arr[i]
    i += 1

In selection sort, we also run the outer loop but instead of starting from the second element, we start from the first element. Then inner loop will loop the current + i element to the end of array to find the minimum element and we will swapped with the current index.

def selection_sort(arr):
    i = 0
    while i < len(arr):
        min_idx = i
        for j in range(i + 1, len(arr)):
            if arr[min_idx] > arr[j]:
                min_idx = j
        arr[i], arr[min_idx] = arr[min_idx], arr[i]
    i += 1

You can do it with dynamic_cast (at least for polymorphic types).

Actually, on second thought--you can't tell if it is SPECIFICALLY a particular type with dynamic_cast--but you can tell if it is that type or any subclass thereof.

template <class DstType, class SrcType>
bool IsType(const SrcType* src)
{
  return dynamic_cast<const DstType*>(src) != nullptr;
}

This language feature is convenient in this situation.

public String getName() {
  return (String) memberHashMap.get("Name");
}

If memberHashMap.get("Name") returns null, you'd still want the method above to return null without throwing an exception. No matter what the class is, null is null.

Try putting display: block in the <li> tags instead of the <ul>

I have developed an Excel VBA Macro for cutting and pasting any selection from Excel into SQL Server, creating a new table. The macro is great for quick and dirty table creations up to a few thousand rows and multiple columns (It can theoretically manage up to 200 columns). The macro attempts to automatically detect header names and assign the most appropriate datatype to each column (it handles varchar columns upto 1000 chars).

Recommended Setup procedure:

1. Make sure Excel is enabled to run macros. (File->Options->Trust Center->Trust Center Settings->Macro Settings->Enable all macros..)
2. Copy the VBA code below to the module associated with your personal workbook (So that the Macro will be available for all worksheets)
3. Assign an appropriate keystroke to the macro ( I have assigned Ctrl Shift X)
4. Save your personal workbook

Use of Macro

1. Select the cells in Excel (including column headers if they exist) to be transferred to SQL
2. Press the assigned keyword combination that you have assigned to run the macro
3. Follow the prompts. (Default table name is ##Table)
4. Paste the clipboard contents into a SSMS window and run the generated SQL code. BriFri 238

One line with no dependencies:

new URLSearchParams(obj).toString();
// OUT: param1=something&param2=somethingelse&param3=another&param4=yetanother

Use it with the URL builtin like so:

let obj = { param1: 'something', param2: 'somethingelse', param3: 'another' }
obj['param4'] = 'yetanother';
const url = new URL(`your_url.com`);
url.search = new URLSearchParams(obj);
const response = await fetch(url);

You can try this code to get HTTP status code from WebException or from OpenReadCompletedEventArgs.Error. It works in Silverlight too because SL does not have WebExceptionStatus.ProtocolError defined.

HttpStatusCode GetHttpStatusCode(System.Exception err)
{
    if (err is WebException)
    {
        WebException we = (WebException)err;
        if (we.Response is HttpWebResponse)
        {
            HttpWebResponse response = (HttpWebResponse)we.Response;
            return response.StatusCode;
        }
    }
    return 0;
}

Don't use cat as some have mentioned here. cat is a program while echo and printf are bash (shell) builtins. Launching a program or another script (also mentioned above) means to create a new process with all its costs. Using builtins, writing functions is quite cheap, because there is no need to create (execute) a process (-environment).

The opener asks "is there any standard tool to output (pipe) to stderr", the short answer is : NO ... why? ... redirecting pipes is an elementary concept in systems like unix (Linux...) and bash (sh) builds up on these concepts.

I agree with the opener that redirecting with notations like this: &2>1 is not very pleasant for modern programmers, but that's bash. Bash was not intended to write huge and robust programs, it is intended to help the admins to get there work with less keypresses ;-)

And at least, you can place the redirection anywhere in the line:

$ echo This message >&2 goes to stderr 
This message goes to stderr

Using position: sticky on th will do the trick.

Note: if you use position: sticky on thead or tr, it won't work.

Running from the command line means running from the terminal or DOS shell. You are running it from Python itself.

If you're implementing a class that's not instantiated by Spring, like a JsonDeserializer you can use:

WebApplicationContext context = ContextLoader.getCurrentWebApplicationContext();
MyClass myBean = context.getBean(MyClass.class);

The best place to understand the difference is at the official documentation on values / values_list. It has many useful examples and explains it very clearly. The django docs are very user freindly.

Here's a short snippet to keep SO reviewers happy:

values

Returns a QuerySet that returns dictionaries, rather than model instances, when used as an iterable.

And read the section which follows it:

value_list

This is similar to values() except that instead of returning dictionaries, it returns tuples when iterated over.

I created a plugin which allows you to drop some files onto a given area. This plugin currently works in Firefox, Safari and Chrome.

The terms of BYTE and WORD are relative to the size of the processor that is being referred to. The most common processors are/were 8 bit, 16 bit, 32 bit or 64 bit. These are the WORD lengths of the processor. Actually half of a WORD is a BYTE, whatever the numerical length is. Ready for this, half of a BYTE is a NIBBLE.

Or with the power of Java 8 Optional, you also can do such trick:

Optional.ofNullable(boolValue).orElse(false)

I did a fun hack to solve this issue to my satisfaction. I've got an AJAX site that loads content dynamically, then modifies the window.location.hash, and I had code to run upon $(document).ready() to parse the hash and load the appropriate section. The thing is that I was perfectly happy with my section loading code for navigation, but wanted to add a way to intercept the browser back and forward buttons, which change the window location, but not interfere with my current page loading routines where I manipulate the window.location, and polling the window.location at constant intervals was out of the question.

What I ended up doing was creating an object as such:

var pageload = {
    ignorehashchange: false,
    loadUrl: function(){
        if (pageload.ignorehashchange == false){
            //code to parse window.location.hash and load content
        };
    }
};

Then, I added a line to my site script to run the pageload.loadUrl function upon the hashchange event, as such:

window.addEventListener("hashchange", pageload.loadUrl, false);

Then, any time I want to modify the window.location.hash without triggering this page loading routine, I simply add the following line before each window.location.hash = line:

pageload.ignorehashchange = true;

and then the following line after each hash modification line:

setTimeout(function(){pageload.ignorehashchange = false;}, 100);

So now my section loading routines are usually running, but if the user hits the 'back' or 'forward' buttons, the new location is parsed and the appropriate section loaded.

An integral type representing the smallest value possible. In other words your program should think in cents not in dollars/euros.

This should not stop you from having the gui translate it back to dollars/euros.

java -cp CLASSPATH is necesssary if you wish to specify all code in the classpath. This is useful for debugging code.

The jarred executable format: java -jar JarFile can be used if you wish to start the app with a single short command. You can specify additional dependent jar files in your MANIFEST using space separated jars in a Class-Path entry, e.g.:

Class-Path: mysql.jar infobus.jar acme/beans.jar

Both are comparable in terms of performance.

With Swift 5, Array has two methods called sorted() and sorted(by:). The first method, sorted(), has the following declaration:

Returns the elements of the collection, sorted.

func sorted() -> [Element]

The second method, sorted(by:), has the following declaration:

Returns the elements of the collection, sorted using the given predicate as the comparison between elements.

func sorted(by areInIncreasingOrder: (Element, Element) throws -> Bool) rethrows -> [Element]

#1. Sort with ascending order for comparable objects

If the element type inside your collection conforms to Comparable protocol, you will be able to use sorted() in order to sort your elements with ascending order. The following Playground code shows how to use sorted():

class ImageFile: CustomStringConvertible, Comparable {

    let fileName: String
    let fileID: Int
    var description: String { return "ImageFile with ID: \(fileID)" }

    init(fileName: String, fileID: Int) {
        self.fileName = fileName
        self.fileID = fileID
    }

    static func ==(lhs: ImageFile, rhs: ImageFile) -> Bool {
        return lhs.fileID == rhs.fileID
    }

    static func <(lhs: ImageFile, rhs: ImageFile) -> Bool {
        return lhs.fileID < rhs.fileID
    }

}

let images = [
    ImageFile(fileName: "Car", fileID: 300),
    ImageFile(fileName: "Boat", fileID: 100),
    ImageFile(fileName: "Plane", fileID: 200)
]

let sortedImages = images.sorted()
print(sortedImages)

/*
 prints: [ImageFile with ID: 100, ImageFile with ID: 200, ImageFile with ID: 300]
 */

#2. Sort with descending order for comparable objects

If the element type inside your collection conforms to Comparable protocol, you will have to use sorted(by:) in order to sort your elements with a descending order.

class ImageFile: CustomStringConvertible, Comparable {

    let fileName: String
    let fileID: Int
    var description: String { return "ImageFile with ID: \(fileID)" }

    init(fileName: String, fileID: Int) {
        self.fileName = fileName
        self.fileID = fileID
    }

    static func ==(lhs: ImageFile, rhs: ImageFile) -> Bool {
        return lhs.fileID == rhs.fileID
    }

    static func <(lhs: ImageFile, rhs: ImageFile) -> Bool {
        return lhs.fileID < rhs.fileID
    }

}

let images = [
    ImageFile(fileName: "Car", fileID: 300),
    ImageFile(fileName: "Boat", fileID: 100),
    ImageFile(fileName: "Plane", fileID: 200)
]

let sortedImages = images.sorted(by: { (img0: ImageFile, img1: ImageFile) -> Bool in
    return img0 > img1
})
//let sortedImages = images.sorted(by: >) // also works
//let sortedImages = images.sorted { $0 > $1 } // also works
print(sortedImages)

/*
 prints: [ImageFile with ID: 300, ImageFile with ID: 200, ImageFile with ID: 100]
 */

#3. Sort with ascending or descending order for non-comparable objects

If the element type inside your collection DOES NOT conform to Comparable protocol, you will have to use sorted(by:) in order to sort your elements with ascending or descending order.

class ImageFile: CustomStringConvertible {

    let fileName: String
    let fileID: Int
    var description: String { return "ImageFile with ID: \(fileID)" }

    init(fileName: String, fileID: Int) {
        self.fileName = fileName
        self.fileID = fileID
    }

}

let images = [
    ImageFile(fileName: "Car", fileID: 300),
    ImageFile(fileName: "Boat", fileID: 100),
    ImageFile(fileName: "Plane", fileID: 200)
]

let sortedImages = images.sorted(by: { (img0: ImageFile, img1: ImageFile) -> Bool in
    return img0.fileID < img1.fileID
})
//let sortedImages = images.sorted { $0.fileID < $1.fileID } // also works
print(sortedImages)

/*
 prints: [ImageFile with ID: 300, ImageFile with ID: 200, ImageFile with ID: 100]
 */

Note that Swift also provides two methods called sort() and sort(by:) as counterparts of sorted() and sorted(by:) if you need to sort your collection in-place.

Quoted from https://developer.mozilla.org/en/DOM/element.click

The click method is intended to be used with INPUT elements of type button, checkbox, radio, reset or submit. Gecko does not implement the click method on other elements that might be expected to respond to mouse–clicks such as links (A elements), nor will it necessarily fire the click event of other elements.

Non–Gecko DOMs may behave differently.

Unfortunately it sounds like you have already discovered the best solution to your problem.

As a side note, I agree that your solution seems less than ideal, but if you encapsulate the functionality inside a method (much like JQuery would do) it is not so bad.

You can use JSON.stringify like:

JSON.stringify(new_tweets);

I resolved in This Way (it's a little bit laboriouse, but it's surely the faster in runtime).

In VB (sorry, but I think it's not hard translate it in C#), I make this substitution with RE:

(?<Attr><(.*ComponentModel\.)Bindable\(True\)>)( |\r\n)*(?<Def>(Public|Private|Friend|Protected) .*Property )(?<Name>[^ ]*) As (?<Type>.*?)[ |\r\n](?![ |\r\n]*Get)

with:

Private _${Name} As ${Type}\r\n${Attr}\r\n${Def}${Name} As ${Type}\r\nGet\r\nReturn _${Name}\r\nEnd Get\r\nSet (Value As ${Type})\r\nIf _${Name} <> Value Then \r\n_${Name} = Value\r\nRaiseEvent PropertyChanged(Me, New ComponentModel.PropertyChangedEventArgs("${Name}"))\r\nEnd If\r\nEnd Set\r\nEnd Property\r\n

This transofrm all code like this:

<Bindable(True)>
Protected Friend Property StartDate As DateTime?

In

Private _StartDate As DateTime?
<Bindable(True)>
Protected Friend Property StartDate As DateTime?
    Get
        Return _StartDate
    End Get
    Set(Value As DateTime?)
        If _StartDate <> Value Then
            _StartDate = Value
            RaiseEvent PropertyChange(Me, New ComponentModel.PropertyChangedEventArgs("StartDate"))
        End If
    End Set
End Property

And If I want to have a more readable code, I can be the opposite just making the following substitution:

Private _(?<Name>.*) As (?<Type>.*)[\r\n ]*(?<Attr><(.*ComponentModel\.)Bindable\(True\)>)[\r\n ]*(?<Def>(Public|Private|Friend|Protected) .*Property )\k<Name> As \k<Type>[\r\n ]*Get[\r\n ]*Return _\k<Name>[\r\n ]*End Get[\r\n ]*Set\(Value As \k<Type>\)[\r\n ]*If _\k<Name> <> Value Then[\r\n ]*_\k<Name> = Value[\r\n ]*RaiseEvent PropertyChanged\(Me, New (.*ComponentModel\.)PropertyChangedEventArgs\("\k<Name>"\)\)[\r\n ]*End If[\r\n ]*End Set[\r\n ]*End Property

With

${Attr} ${Def} ${Name} As ${Type}

I throw to replace the IL code of the set method, but I can't write a lot of compiled code in IL... If a day I write it, I'll say you!

Its not possible to access any PHP function inside Twig directly.

What you can do is write a Twig extension. A common structure is, writing a service with some utility functions, write a Twig extension as bridge to access the service from twig. The Twig extension will use the service and your controller can use the service too.

Take a look: http://symfony.com/doc/current/cookbook/templating/twig_extension.html

Cheers.

Wait and Sleep functions lock Excel and you can't do anything else until the delay finishes. On the other hand Loop delays doesn't give you an exact time to wait.

So, I've made this workaround joining a little bit of both concepts. It loops until the time is the time you want.

Private Sub Waste10Sec()
   target = (Now + TimeValue("0:00:10"))
   Do
       DoEvents 'keeps excel running other stuff
   Loop Until Now >= target
End Sub

You just need to call Waste10Sec where you need the delay

Put the line in a stringstream and extract word by word back:

#include <iostream>
#include <sstream>
using namespace std;

int main()
{
    string t;
    getline(cin,t);

    istringstream iss(t);
    string word;
    while(iss >> word) {
        /* do stuff with word */
    }
}

Of course, you can just skip the getline part and read word by word from cin directly.

And here you can read why is using namespace std considered bad practice.

Here 2 options for subsetting:

Using subset from base R:

library(ggplot2)
ggplot(subset(dat,ID %in% c("P1" , "P3"))) + 
         geom_line(aes(Value1, Value2, group=ID, colour=ID))

Using subset the argument of geom_line(Note I am using plyr package to use the special . function).

library(plyr)
ggplot(data=dat)+ 
  geom_line(aes(Value1, Value2, group=ID, colour=ID),
                ,subset = .(ID %in% c("P1" , "P3")))

You can also use the complementary subsetting:

subset(dat,ID != "P2")

  Boolean condition=false;  //Instance variable declaration.

Working Example

             <RatingBar
                style="@style/RatingBar"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:numStars="5"
                android:rating="3.5"
                android:stepSize="0.5" />

and add this in your styles xml file

<style name="RatingBar"   
parent="android:style/Widget.Material.RatingBar.Small">
<item name="colorControlNormal">@color/primary_light</item>
<item name="colorControlActivated">@color/primary_dark</item>
</style>

This way you dont need to customise ratingBar.

This is a modification of Linus Kleen's answer. His answer didn't work for me because there would be a . added in front of the file path which cp doesn't like (the path would look like source/.destination/file).

This command worked for me:

find . -type f -not -path '*/exlude-path/*' -exec cp --parents '{}' '/destination/' \;

the --parents command preserves the directory structure.

Play around with this jsFiddle example:

HTML:

<p id="foo" name="bar">Hello, world!</p>

jQuery:

$(function() {
    var name = $('#foo').attr('name');

    alert(name);
    console.log(name);
});

This uses jQuery's .attr() method to get value for the first element in the matched set.

While not specifically jQuery, the result is shown as an alert prompt and written to the browser's console.

Place your script inside the body tag

<body>
  // Rest of html
  <script>
  function hideButton() {
    $(".loading").hide();
  }
function showButton() {
  $(".loading").show();
}
</script> 
< /body>

If you check this JSFIDDLE and click on javascript, you will see the load Type body is selected

You are quite right to be concerned - static method calls are particularly problematic for unit testing as you cannot easily mock your dependencies. What I am going to show you is how to let the Spring IoC container do the dirty work for you, leaving you with neat, testable code. SecurityContextHolder is a framework class and while it may be ok for your low-level security code to be tied to it, you probably want to expose a neater interface to your UI components (i.e. controllers).

cliff.meyers mentioned one way around it - create your own "principal" type and inject an instance into consumers. The Spring <aop:scoped-proxy/> tag introduced in 2.x combined with a request scope bean definition, and the factory-method support may be the ticket to the most readable code.

It could work like following:

public class MyUserDetails implements UserDetails {
    // this is your custom UserDetails implementation to serve as a principal
    // implement the Spring methods and add your own methods as appropriate
}

public class MyUserHolder {
    public static MyUserDetails getUserDetails() {
        Authentication a = SecurityContextHolder.getContext().getAuthentication();
        if (a == null) {
            return null;
        } else {
            return (MyUserDetails) a.getPrincipal();
        }
    }
}

public class MyUserAwareController {        
    MyUserDetails currentUser;

    public void setCurrentUser(MyUserDetails currentUser) { 
        this.currentUser = currentUser;
    }

    // controller code
}

Nothing complicated so far, right? In fact you probably had to do most of this already. Next, in your bean context define a request-scoped bean to hold the principal:

<bean id="userDetails" class="MyUserHolder" factory-method="getUserDetails" scope="request">
    <aop:scoped-proxy/>
</bean>

<bean id="controller" class="MyUserAwareController">
    <property name="currentUser" ref="userDetails"/>
    <!-- other props -->
</bean>

Thanks to the magic of the aop:scoped-proxy tag, the static method getUserDetails will be called every time a new HTTP request comes in and any references to the currentUser property will be resolved correctly. Now unit testing becomes trivial:

protected void setUp() {
    // existing init code

    MyUserDetails user = new MyUserDetails();
    // set up user as you wish
    controller.setCurrentUser(user);
}

Hope this helps!

brilliant example Jonathan Leffler, to make your code work on SLES, I needed to add an additional header to allow the pid_t object :)

Here is the inline version, although not recommended I show it here in case you need to add validation without being able to refactor the code

function validate(theForm) { // passing the form object
  var val = theForm.textField1.value;
  if (val==null || val.trim()=="") { 
    alert('Please enter something');
    theForm.textField1.focus();
    return false; // cancel submission
  }
  return true; // allow submit
}

passing the form object in (this)

<form onsubmit="return validate(this)">
  <input type="text" name="textField1" value="" /><br/>
  <input type="submit" />
</form>

Ok, the way I see it you have 3 options.

1: If you simply wish to check whether the number is an integer, and don't care about converting it, but simply wish to keep it as a string and don't care about potential overflows, checking whether it matches a regex for an integer would be ideal here.

2: You can use boost::lexical_cast and then catch a potential boost::bad_lexical_cast exception to see if the conversion failed. This would work well if you can use boost and if failing the conversion is an exceptional condition.

3: Roll your own function similar to lexical_cast that checks the conversion and returns true/false depending on whether it's successful or not. This would work in case 1 & 2 doesn't fit your requirements.

Check the Variables section in the Go template docs. A range may declare two variables, separated by a comma. The following should work:

{{ range $key, $value := . }}
   <li><strong>{{ $key }}</strong>: {{ $value }}</li>
{{ end }}

Here is the complete sequence for sql server :

1.  FROM
2.  ON
3.  JOIN
4.  WHERE
5.  GROUP BY
6.  WITH CUBE or WITH ROLLUP
7.  HAVING
8.  SELECT
9.  DISTINCT
10. ORDER BY
11. TOP

So from the above list, you can easily understand the execution sequence of GROUP BY, HAVING and WHERE which is :

1.  WHERE
2.  GROUP BY
3.  HAVING

Get more information about it from Microsoft

For any array of length n, elements of the array will have an index from 0 to n-1.

If your program is trying to access any element (or memory) having array index greater than n-1, then Java will throw ArrayIndexOutOfBoundsException

So here are two solutions that we can use in a program

1. Maintaining count:

   for(int count = 0; count < array.length; count++) {
       System.out.println(array[count]);
   }
   

   Or some other looping statement like

   int count = 0;
   while(count < array.length) {
       System.out.println(array[count]);
       count++;
   }
   

2. A better way go with a for each loop, in this method a programmer has no need to bother about the number of elements in the array.

   for(String str : array) {
       System.out.println(str);
   }
   

you can use the keyword 'In' and pass the List argument. e.g : findByInventoryIdIn

 List<AttributeHistory> findByValueIn(List<String> values);

Use

export LD_LIBRARY_PATH="/path/to/library/"

in your .bashrc otherwise, it'll only be available to bash and not any programs you start.

Try -R/path/to/library/ flag when you're linking, it'll make the program look in that directory and you won't need to set any environment variables.

EDIT: Looks like -R is Solaris only, and you're on Linux.

An alternate way would be to add the path to /etc/ld.so.conf and run ldconfig. Note that this is a global change that will apply to all dynamically linked binaries.

If you want a string, then the other answers are fine, but if what you're looking for is the first few letters as characters you can access them as a list:

your_text.chars.take(30)

You can also use day names like Mon for Monday, Tue for Tuesday, etc. It's more human friendly.

There are two ways to interpret the input data; either -128 is the lowest value, and 127 is the highest (i.e. true signed data), or 0 is the lowest value, 127 is somewhere in the middle, and the next "higher" number is -128, with -1 being the "highest" value (that is, the most significant bit already got misinterpreted as a sign bit in a two's complement notation.

Assuming you mean the latter, the formally correct way is

signed char in = ...
unsigned char out = (in < 0)?(in + 256):in;

which at least gcc properly recognizes as a no-op.

Sounds like you'd like to use toLocaleString() on your numeric inputs.

See https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Number/toLocaleString for its usage.

Localization of numbers in JS is also covered in Internationalization(Number formatting "num.toLocaleString()") not working for chrome

If you have a backend server asking for the Basic Auth credentials before the app then this is sufficient, it will re-use that then:

fetch(url, {
  credentials: 'include',
}).then(...);

You must initialize your List seeAlso :

List<String> seeAlso = new Vector<String>();

or

List<String> seeAlso = new ArrayList<String>();

>>> s1 ='arbit'
>>> s2 = 'hello world '.join( [s]*3 )
>>> print s2
arbit hello world arbit hello world arbit

Starting from Python 3.1, you can use importlib :

import importlib  
foobar = importlib.import_module("foo-bar")

( https://docs.python.org/3/library/importlib.html )

from command console, if you get this error you can avoid it by typing

c:\> sqlplus /nolog

then you can connect

SQL> conn user/pass @host:port/service

This worked for me:

ActiveWindow.SmallScroll down:=0

or more simply:

ActiveWindow.SmallScroll 0

For those of us who did not see -1 by Michal Chaniewski, the complete line of code:

Tried the options above on Ubuntu 14.04, but they would constantly produce this error:

npm ERR! tar pack Error reading /root/tmp/npm-15864/1465947804069-0.4854120113886893/package

Then found this solution online:

1) Clean the cache of npm first:

sudo npm cache clean -f

2) Install n module of npm:

sudo npm install -g n

3) Begin the installation by selecting the version of node to install: stable or latest, we will use stable here:

sudo n stable

4) Check the version of node:

node -v

5) Check the version of npm:

npm -v

Unit testing is meant for testing the very basic functionality (the lowest level functions of the application) to be sure that your application building blocks work correctly. There is probably no formal definition of what does that exactly mean, but you should consider other kinds of testing for the bigger functionality -- see Integration testing. The unit testing framework may not be ideal for the purpose.

@Masci is correct, but in case you're using C (and the gcc compiler) take in account that this doesn't work:

gcc -ldl dlopentest.c

But this does:

gcc dlopentest.c -ldl

Took me a bit to figure out...

You can also try using flex-box

<head><style>
body {
    color:white;
    font-family:arial;
    font-size:1.2em;
}
form {
    margin:0 auto;
    padding:20px;
    background:#444;
}
.input-group {
    margin-top:10px;
    width:60%;
    display:flex;
    justify-content:space-between;
    flex-wrap:wrap;
}
label, input {
    flex-basis:100px;
}
</style></head>
<body>

<form>
    <div class="wrapper">
        <div class="input-group">
            <label for="user_name">name:</label>
            <input type="text" id="user_name">
        </div>
        <div class="input-group">
            <label for="user_pass">Password:</label>
            <input type="password" id="user_pass">
        </div>
    </div>
</form>

</body>
</html>

It's easier for me to think in these terms, but borrowing from other answers. The value you want is located in the series:

df[*column*][*row*]

where column and row point to the value you want returned. For your example, column is 'A' and for row you use a mask:

df['B'] == 3

To get the value from the series there are several options:

df['A'][df['B'] == 3].values[0]
df['A'][df['B'] == 3].iloc[0]
df['A'][df['B'] == 3].to_numpy()[0]

You can add and retrieve a numpy array from dataframe using this:

import numpy as np
import pandas as pd

df = pd.DataFrame({'b':range(10)}) # target dataframe
a = np.random.normal(size=(10,2)) # numpy array
df['a']=a.tolist() # save array
np.array(df['a'].tolist()) # retrieve array

This builds on the previous answer that confused me because of the sparse part and this works well for a non-sparse numpy arrray.

Take a look at Job Control on UNIX systems

If you don't have control of your shell, simply hitting ctrl + C should stop the process. If that doesn't work, you can try ctrl + Z and using the jobs and kill -9 %<job #> to kill it. The '-9' is a type of signal. You can man kill to see a list of signals.

I had similar issue and the below line helped me solving the issue.Thanks to rene. I just pasted this line above the authentication code and it worked

ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;

For objects array use map with indexOf:

var imageList = [_x000D_
   {value: 100},_x000D_
   {value: 200},_x000D_
   {value: 300},_x000D_
   {value: 400},_x000D_
   {value: 500}_x000D_
];_x000D_
_x000D_
var index = imageList.map(function (img) { return img.value; }).indexOf(200);_x000D_
_x000D_
console.log(index);

In modern browsers you can use findIndex:

var imageList = [_x000D_
   {value: 100},_x000D_
   {value: 200},_x000D_
   {value: 300},_x000D_
   {value: 400},_x000D_
   {value: 500}_x000D_
];_x000D_
_x000D_
var index = imageList.findIndex(img => img.value === 200);_x000D_
_x000D_
console.log(index);

Its part of ES6 and supported by Chrome, FF, Safari and Edge

String filePath = Environment.getExternalStorageDirectory()+"/yourfolderNAme/yopurfile.mp3";
mediaPlayer = new  MediaPlayer();
mediaPlayer.setDataSource(filePath);
mediaPlayer.prepare();   
mediaPlayer.start()

and this play from raw folder.

int resID = myContext.getResources().getIdentifier(playSoundName,"raw",myContext.getPackageName());

            MediaPlayer mediaPlayer = MediaPlayer.create(myContext,resID);
            mediaPlayer.prepare();
            mediaPlayer.start();

mycontext=application.this. use.

Tests

On the Tests class we will add an @XmlRootElement annotation. Doing this will let your JAXB implementation know that when a document starts with this element that it should instantiate this class. JAXB is configuration by exception, this means you only need to add annotations where your mapping differs from the default. Since the testData property differs from the default mapping we will use the @XmlElement annotation. You may find the following tutorial helpful: http://wiki.eclipse.org/EclipseLink/Examples/MOXy/GettingStarted

package forum11221136;

import javax.xml.bind.annotation.*;

@XmlRootElement
public class Tests {

    TestData testData;

    @XmlElement(name="test-data")
    public TestData getTestData() {
        return testData;
    }

    public void setTestData(TestData testData) {
        this.testData = testData;
    }

}

TestData

On this class I used the @XmlType annotation to specify the order in which the elements should be ordered in. I added a testData property that appeared to be missing. I also used an @XmlElement annotation for the same reason as in the Tests class.

package forum11221136;

import java.util.List;
import javax.xml.bind.annotation.*;

@XmlType(propOrder={"title", "book", "count", "testData"})
public class TestData {
    String title;
    String book;
    String count;
    List<TestData> testData;

    public String getTitle() {
        return title;
    }
    public void setTitle(String title) {
        this.title = title;
    }
    public String getBook() {
        return book;
    }
    public void setBook(String book) {
        this.book = book;
    }
    public String getCount() {
        return count;
    }
    public void setCount(String count) {
        this.count = count;
    }
    @XmlElement(name="test-data")
    public List<TestData> getTestData() {
        return testData;
    }
    public void setTestData(List<TestData> testData) {
        this.testData = testData;
    }
}

Demo

Below is an example of how to use the JAXB APIs to read (unmarshal) the XML and populate your domain model and then write (marshal) the result back to XML.

package forum11221136;

import java.io.File;
import javax.xml.bind.*;

public class Demo {

    public static void main(String[] args) throws Exception {
        JAXBContext jc = JAXBContext.newInstance(Tests.class);

        Unmarshaller unmarshaller = jc.createUnmarshaller();
        File xml = new File("src/forum11221136/input.xml");
        Tests tests = (Tests) unmarshaller.unmarshal(xml);

        Marshaller marshaller = jc.createMarshaller();
        marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
        marshaller.marshal(tests, System.out);
    }

}

This question already has the answer for defining function pointers, however they can get very messy, especially if you are going to be passing them around your application. To avoid this unpleasantness I would recommend that you typedef the function pointer into something more readable. For example.

typedef void (*functiontype)();

Declares a function that returns void and takes no arguments. To create a function pointer to this type you can now do:

void dosomething() { }

functiontype func = &dosomething;
func();

For a function that returns an int and takes a char you would do

typedef int (*functiontype2)(char);

and to use it

int dosomethingwithchar(char a) { return 1; }

functiontype2 func2 = &dosomethingwithchar
int result = func2('a');

There are libraries that can help with turning function pointers into nice readable types. The boost function library is great and is well worth the effort!

boost::function<int (char a)> functiontype2;

is so much nicer than the above.

Because ( is special in regex, you should escape it \( when matching. However, depending on what language you are using, you can easily match ( with string methods like index() or other methods that enable you to find at what position the ( is in. Sometimes, there's no need to use regex.

I updated to Xcode v7.3.1 and it solved the issue.

onCreate() method gets called when activity gets created, and its called only once in whole Activity life cycle. where as onStart() is called when activity is stopped... I mean it has gone to background and its onStop() method is called by the os. onStart() may be called multiple times in Activity life cycle.More details here

You can't. All you can do is to make that image as small as possible and set some cache invalidation headers (Expires, Cache-Control) far in the future. Here's what Yahoo! has to say about favicon.ico requests.

The all above not work for me, I have just checked this and its work :

vertical-align: super;

 <div id="lbk_mng_rdooption" style="float: left;">
     <span class="bold" style="vertical-align: super;">View:</span>
 </div>

I know by padding or margin will work, but that is last choise I prefer.

The strcomp function may be appropriate here (returns 0 when strings are identical):

 SELECT * from table WHERE Strcmp(user, testername) <> 0;

I find you need the following:

• A top constraint
• A leading constraint (eg left side)
• A trailing constraint (eg right side)
• Set content hugging priority, horizontal to low, so it'll fill the given space if the text is short.
• Set content compression resistance, horizontal to low, so it'll wrap instead of try to become wider.
• Set the number of lines to 0.
• Set the line break mode to word wrap.

1. Edit POM.xml

Add the following property in pom.xml. Make sure you use the fully qualified class name (i.e. with package name) which contains the main method:

<properties>
        <exec.mainClass>fully-qualified-class-name</exec.mainClass>
</properties>

2. Run Command

Now from the terminal, trigger the following command:

mvn clean compile exec:java

NOTE You can pass further arguments via -Dexec.args="xxx" flag.

I found that my version of Xcode was too outdated and installing command-line-tools wasn't helping. Here's what I did:

• I completely uninstalled the outdated XCode
• I reinstalled the most recent XCode from the app store
• That was all. Git was restored.

A printer doesn't understand pixels, it understand dots (pt in CSS). The best solution is to write an extra CSS for printing, with all of its measures in dots.

Then, in your HTML code, in head section, put:

<link href="style.css" rel="stylesheet" type="text/css" media="screen">
<link href="style_print.css" rel="stylesheet" type="text/css" media="print">

Use the splice method.

ArrayName.splice(indexValueOfArray,1);

This removes 1 item from the array starting at indexValueOfArray.

I had a git conflict left in my workspace.xml i.e.

<<<<———————HEAD

which caused the unknown tag error. It is a bit annoying that it doesn’t name the file.

ngSrc is a native directive, so it seems you want a similar directive that modifies your div's background-image style.

You could write your own directive that does exactly what you want. For example

app.directive('backImg', function(){
    return function(scope, element, attrs){
        var url = attrs.backImg;
        element.css({
            'background-image': 'url(' + url +')',
            'background-size' : 'cover'
        });
    };
});?

Which you would invoke like this

<div back-img="<some-image-url>" ></div>
