To answer your question:

import urllib

link = "http://www.somesite.com/details.pl?urn=2344"
f = urllib.urlopen(link)
myfile = f.read()
print(myfile)

You need to read(), not readline()

EDIT (2018-06-25): Since Python 3, the legacy urllib.urlopen() was replaced by urllib.request.urlopen() (see notes from https://docs.python.org/3/library/urllib.request.html#urllib.request.urlopen for details).

If you're using Python 3, see answers by Martin Thoma or i.n.n.m within this question: https://stackoverflow.com/a/28040508/158111 (Python 2/3 compat) https://stackoverflow.com/a/45886824/158111 (Python 3)

Or, just get this library here: http://docs.python-requests.org/en/latest/ and seriously use it :)

import requests

link = "http://www.somesite.com/details.pl?urn=2344"
f = requests.get(link)
print(f.text)

The redis SET command stores a string, not arbitrary data. You could try using the redis HSET command to store the dict as a redis hash with something like

for k,v in my_dict.iteritems():
    r.hset('my_dict', k, v)

but the redis datatypes and python datatypes don't quite line up. Python dicts can be arbitrarily nested, but a redis hash is going to require that your value is a string. Another approach you can take is to convert your python data to string and store that in redis, something like

r.set('this_dict', str(my_dict))

and then when you get the string out you will need to parse it to recreate the python object.

You can assign values in the loop using df.set_value:

for i, row in df.iterrows():
    ifor_val = something
    if <condition>:
        ifor_val = something_else
    df.set_value(i,'ifor',ifor_val)

If you don't need the row values you could simply iterate over the indices of df, but I kept the original for-loop in case you need the row value for something not shown here.

update

df.set_value() has been deprecated since version 0.21.0 you can use df.at() instead:

for i, row in df.iterrows():
    ifor_val = something
    if <condition>:
        ifor_val = something_else
    df.at[i,'ifor'] = ifor_val

To see the default version of swift installed on your machine then from the command line, type the following :

swift --version

Apple Swift version 4.1.2 (swiftlang-902.0.54 clang-902.0.39.2)

Target: x86_64-apple-darwin17.6.0

This is most likely the version that is included in the app store version of Xcode that you have installed (unless you have changed it).

If you want to determine the actual version of Swift being used by a particular version of Xcode (a beta, for instance) then from the command line, invoke the swift binary within the Xcode bundle and pass it the parameter --version

/Applications/Xcode-beta.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/swift --version

Apple Swift version 4.2 (swiftlang-1000.0.16.7 clang-1000.10.25.3)

Target: x86_64-apple-darwin17.6.0

AlliterativeAlice's example helped me tremendously. In my case, though, the server I was talking to didn't like having single quotes around utf-8 in the content type. It failed with a generic "Server Error" and it took hours to figure out what it didn't like:

request.ContentType = "text/xml; encoding=utf-8";

That's it.

Look at the static System.Drawing.Printing.PrinterSettings.InstalledPrinters property.

It is a list of the names of all installed printers on the system.

Here is an example of using super():

#New-style classes inherit from object, or from another new-style class
class Dog(object):

    name = ''
    moves = []

    def __init__(self, name):
        self.name = name

    def moves_setup(self):
        self.moves.append('walk')
        self.moves.append('run')

    def get_moves(self):
        return self.moves

class Superdog(Dog):

    #Let's try to append new fly ability to our Superdog
    def moves_setup(self):
        #Set default moves by calling method of parent class
        super(Superdog, self).moves_setup()
        self.moves.append('fly')

dog = Superdog('Freddy')
print dog.name # Freddy
dog.moves_setup()
print dog.get_moves() # ['walk', 'run', 'fly']. 
#As you can see our Superdog has all moves defined in the base Dog class

Here's a one-liner to get the filename for a module, suitable for shell aliasing:

echo 'import sys; t=__import__(sys.argv[1],fromlist=[\".\"]); print(t.__file__)'  | python - 

Set up as an alias:

alias getpmpath="echo 'import sys; t=__import__(sys.argv[1],fromlist=[\".\"]); print(t.__file__)'  | python - "

To use:

$ getpmpath twisted
/usr/lib64/python2.6/site-packages/twisted/__init__.pyc
$ getpmpath twisted.web
/usr/lib64/python2.6/site-packages/twisted/web/__init__.pyc

A small note about the efficiency of abovementioned methods:

 library(microbenchmark)

  microbenchmark(
    which("Feb" == month.abb)[[1]],
    which(month.abb %in% "Feb"))

  Unit: nanoseconds
   min     lq    mean median     uq  max neval
   891  979.0 1098.00   1031 1135.5 3693   100
   1052 1175.5 1339.74   1235 1390.0 7399  100

So, the best one is

    which("Feb" == month.abb)[[1]]

With atomic map example

#include <iostream>
#include <map>
#include <vector> 
#include <atomic>

using namespace std;

typedef std::atomic<std::uint32_t> atomic_uint32_t;
typedef std::map<int, atomic_uint32_t> atomic_map_t;

int main()
{
    atomic_map_t m;

    m[4] = 456;
    m[2] = 45678;

    vector<int> v;
    for(map<int,atomic_uint32_t>::iterator it = m.begin(); it != m.end(); ++it) {
      v.push_back(it->second);
      cout << it->first << " "<<it->second<<"\n";
    }

    return 0;

SELECT DISTINCT Col1,Col2 FROM Table GROUP BY Col1 HAVING COUNT( DISTINCT Col1 ) = 1

You have two options to fix the issue:

1- Manually make sure the two versions match.
2- Use the IDE's help as follows:
- Right mouse click on the error in the 'Problems' view
- Select the 'Quick Fix' menu item from the pop-up menu
- Select the right compiler level in the provided dialog and click 'Finish'.

Taken from Eclipse: Java compiler level and project facet mismatch

Yes you can change it. if you call VBscript function within Javascript.

Here is simple example

<script>

function alert_confirm(){

      customMsgBox("This is my title","how are you?",64,0,0,0);
}

</script>


<script language="VBScript">

Function customMsgBox(tit,mess,icon,buts,defs,mode)
   butVal = icon + buts + defs + mode
   customMsgBox= MsgBox(mess,butVal,tit)
End Function

</script>

<html>

You can use the DataColumnCollection of Your datatable to check if the column is in the collection.

Something like:

DataColumnCollection Columns = dtItems.Columns;

if (Columns.Contains(ColNameToCheck))
{
  row["ColNameToCheck"] = "Checked";
}

It is because you haven't qualified Cells(1, 1) with a worksheet object, and the same holds true for Cells(10, 2). For the code to work, it should look something like this:

Dim ws As Worksheet

Set ws = Sheets("SheetName")
Range(ws.Cells(1, 1), ws.Cells(10, 2)).ClearContents

Alternately:

With Sheets("SheetName")
    Range(.Cells(1, 1), .Cells(10, 2)).ClearContents
End With

EDIT: The Range object will inherit the worksheet from the Cells objects when the code is run from a standard module or userform. If you are running the code from a worksheet code module, you will need to qualify Range also, like so:

ws.Range(ws.Cells(1, 1), ws.Cells(10, 2)).ClearContents

or

With Sheets("SheetName")
    .Range(.Cells(1, 1), .Cells(10, 2)).ClearContents
End With

You can use PHP, JSP, ASP or any other server side script to connect with mysql database and and return JSON data that you can parse it to in your android app this link how to do it

I used interop to open Excel and to modify the column widths once the data was done. If you use interop to spit the data into a new Excel workbook (if this is what you want), it will be terribly slow. Instead, I generated a .CSV, then opened the .CSV in Excel. This has its own problems, but I've found this the quickest method.

First, convert the .CSV:

// Convert array data into CSV format.
// Modified from http://csharphelper.com/blog/2018/04/write-a-csv-file-from-an-array-in-c/.
private string GetCSV(List<string> Headers, List<List<double>> Data)
{
    // Get the bounds.
    var rows = Data[0].Count;
    var cols = Data.Count;
    var row = 0;

    // Convert the array into a CSV string.
    StringBuilder sb = new StringBuilder();

    // Add the first field in this row.
    sb.Append(Headers[0]);

    // Add the other fields in this row separated by commas.
    for (int col = 1; col < cols; col++)
        sb.Append("," + Headers[col]);

    // Move to the next line.
    sb.AppendLine();

    for (row = 0; row < rows; row++)
    {
        // Add the first field in this row.
        sb.Append(Data[0][row]);

        // Add the other fields in this row separated by commas.
        for (int col = 1; col < cols; col++)
            sb.Append("," + Data[col][row]);

        // Move to the next line.
        sb.AppendLine();
    }

    // Return the CSV format string.
    return sb.ToString();
}

Then, export it to Excel:

public void ExportToExcel()
{
    // Initialize app and pop Excel on the screen.
    var excelApp = new Excel.Application { Visible = true };

    // I use unix time to give the files a unique name that's almost somewhat useful.
    DateTime dateTime = DateTime.UtcNow;
    long unixTime = ((DateTimeOffset)dateTime).ToUnixTimeSeconds();
    var path = @"C:\Users\my\path\here + unixTime + ".csv";

    var csv = GetCSV();
    File.WriteAllText(path, csv);

    // Create a new workbook and get its active sheet.
    excelApp.Workbooks.Open(path);

    var workSheet = (Excel.Worksheet)excelApp.ActiveSheet;

    // iterate over each value and throw it in the chart
    for (var column = 0; column < Data.Count; column++)
    {
        ((Excel.Range)workSheet.Columns[column + 1]).AutoFit();
    }

    currentSheet = workSheet;
}

You'll have to install some stuff, too...

1. Right click on the solution from solution explorer and select "Manage NuGet Packages." - add Microsoft.Office.Interop.Excel

2. It might actually work right now if you created the project the way interop wants you to. If it still doesn't work, I had to create a new project in a different category. Under New > Project, select Visual C# > Windows Desktop > Console App. Otherwise, the interop tools won't work.

In case I forgot anything, here's my 'using' statements:

using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Text;
using Excel = Microsoft.Office.Interop.Excel;

Also, in some cases is important to check the target folder permissions. To give write permission for the user might be the solution. That worked for me.

I use this: if you declare var x = 0; before the functions declarations, the variable works for all the code files, but the variable will be declare every time that you edit a cell in the spreadsheet

The calculation occurs immediately since the calculation call is bound in the template, which displays its result when quantity changes.

Instead you could try the following approach. Change your markup to the following:

<div ng-controller="myAppController" style="text-align:center">
  <p style="font-size:28px;">Enter Quantity:
      <input type="text" ng-model="quantity"/>
  </p>
  <button ng-click="calculateQuantity()">Calculate</button>
  <h2>Total Cost: Rs.{{quantityResult}}</h2>
</div>

Next, update your controller:

myAppModule.controller('myAppController', function($scope,calculateService) {
  $scope.quantity=1;
  $scope.quantityResult = 0;

  $scope.calculateQuantity = function() {
    $scope.quantityResult = calculateService.calculate($scope.quantity, 10);
  };
});

Here's a JSBin example that demonstrates the above approach.

The problem with this approach is the calculated result remains visible with the old value till the button is clicked. To address this, you could hide the result whenever the quantity changes.

This would involve updating the template to add an ng-change on the input, and an ng-if on the result:

<input type="text" ng-change="hideQuantityResult()" ng-model="quantity"/>

and

<h2 ng-if="showQuantityResult">Total Cost: Rs.{{quantityResult}}</h2>

In the controller add:

$scope.showQuantityResult = false;

$scope.calculateQuantity = function() {
  $scope.quantityResult = calculateService.calculate($scope.quantity, 10);
  $scope.showQuantityResult = true;
};

$scope.hideQuantityResult = function() {
  $scope.showQuantityResult = false;
}; 

These updates can be seen in this JSBin demo.

Here's a much newer Kotlin solution for this which is much simpler than many of the answers written here, it uses anonymous class.

val items = mutableListOf<String>()

inner class ItemHolder(view: View): RecyclerView.ViewHolder(view) {
    var textField: TextView = view.findViewById(android.R.id.text1) as TextView
}

override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
    rvitems.layoutManager = LinearLayoutManager(context)
    rvitems.adapter = object : RecyclerView.Adapter<ItemHolder>() {

        override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): ItemHolder {
            return ItemHolder(LayoutInflater.from(parent.context).inflate(android.R.layout.simple_list_item_1, parent, false))
        }

        override fun getItemCount(): Int {
            return items.size
        }

        override fun onBindViewHolder(holder: ItemHolder, position: Int) {
            holder.textField.text = items[position]
            holder.textField.setOnClickListener {
                Toast.makeText(context, "Clicked $position", Toast.LENGTH_SHORT).show()
            }
        }
    }
}

I took the liberty to use android.R.layout.simple_list_item_1 as it's simpler. I wanted to simplify it even further and put ItemHolder as an inner class but couldn't quite figure out how to reference it in a type in the outer class parameter.

Use the change event of the select:

$('#my_select').change(function()
{
   $(this).parents('td').css('background', '#000000');
});

I should tell you the basic steps and rest depends upon your own effort. You need to perform following steps.

• Create a connection string.
• Create a SQL connection
• Create SQL command
• Create SQL data adapter
• fill your dataset.

Do not forget to open and close connection. follow this link for more under standing.

<?php if ($foo) { ?>
    <div class="mydiv">Condition is true</div>
<?php } else { ?>
    <div class="myotherdiv">Condition is false</div>
<?php } ?>

What you put directly under src/main/java is in the default package, at the root of the classpath. It's the same for resources put under src/main/resources: they end up at the root of the classpath.

So the path of the resource is app-context.xml, not main/resources/app-context.xml.

Try adding use PDO; after your namespace or just before your class or at the top of your PHP file.

Compare them as other values:

if($array_a == $array_b) {
  //they are the same
}

You can read about all array operators here: http://php.net/manual/en/language.operators.array.php Note for example that === also checks that the types and order of the elements in the arrays are the same.

This is an Oracle-specific notation for an outer join. It means that it will include all rows from t1, and use NULLS in the t0 columns if there is no corresponding row in t0.

In standard SQL one would write:

SELECT t0.foo, t1.bar
  FROM FIRST_TABLE t0
 RIGHT OUTER JOIN SECOND_TABLE t1;

Oracle recommends not to use those joins anymore if your version supports ANSI joins (LEFT/RIGHT JOIN) :

Oracle recommends that you use the FROM clause OUTER JOIN syntax rather than the Oracle join operator. Outer join queries that use the Oracle join operator (+) are subject to the following rules and restrictions […]

I would recommend using jQuery with this function:

$(document).ready(function(){
 $('#about').addClass('expand');
});

This will add the expand class to an element with id of about when the dom is ready on page load.

I referred a blog by Kim for doing this and its working fine for me. See the blog

The automated execution of macro can be accomplished with the help of a VB Script file which is being invoked by Windows Task Scheduler at specified times.

Remember to replace 'YourWorkbook' with the name of the workbook you want to open and replace 'YourMacro' with the name of the macro you want to run.

See the VB Script File (just named it RunExcel.VBS):

    ' Create a WshShell to get the current directory
Dim WshShell
Set WshShell = CreateObject("WScript.Shell")

' Create an Excel instance
Dim myExcelWorker
Set myExcelWorker = CreateObject("Excel.Application") 

' Disable Excel UI elements
myExcelWorker.DisplayAlerts = False
myExcelWorker.AskToUpdateLinks = False
myExcelWorker.AlertBeforeOverwriting = False
myExcelWorker.FeatureInstall = msoFeatureInstallNone

' Tell Excel what the current working directory is 
' (otherwise it can't find the files)
Dim strSaveDefaultPath
Dim strPath
strSaveDefaultPath = myExcelWorker.DefaultFilePath
strPath = WshShell.CurrentDirectory
myExcelWorker.DefaultFilePath = strPath

' Open the Workbook specified on the command-line 
Dim oWorkBook
Dim strWorkerWB
strWorkerWB = strPath & "\YourWorkbook.xls"

Set oWorkBook = myExcelWorker.Workbooks.Open(strWorkerWB)

' Build the macro name with the full path to the workbook
Dim strMacroName
strMacroName = "'" & strPath & "\YourWorkbook" & "!Sheet1.YourMacro"
on error resume next 
   ' Run the calculation macro
   myExcelWorker.Run strMacroName
   if err.number <> 0 Then
      ' Error occurred - just close it down.
   End If
   err.clear
on error goto 0 

oWorkBook.Save 

myExcelWorker.DefaultFilePath = strSaveDefaultPath

' Clean up and shut down
Set oWorkBook = Nothing

' Don’t Quit() Excel if there are other Excel instances 
' running, Quit() will shut those down also
if myExcelWorker.Workbooks.Count = 0 Then
   myExcelWorker.Quit
End If

Set myExcelWorker = Nothing
Set WshShell = Nothing

You can test this VB Script from command prompt:

>> cscript.exe RunExcel.VBS

Once you have the VB Script file and workbook tested so that it does what you want, you can then use Microsoft Task Scheduler (Control Panel-> Administrative Tools--> Task Scheduler) to execute ‘cscript.exe RunExcel.vbs’ automatically for you.

Please note the path of the macro should be in correct format and inside single quotes like:

strMacroName = "'" & strPath & "\YourWorkBook.xlsm'" & 
"!ModuleName.MacroName"

In my opinion FirstOrDefault is being overused a lot. In the majority of the cases when you’re filtering data you would either expect to get back a collection of elements matching the logical condition or a single unique element by its unique identifier – such as a user, book, post etc... That’s why we can even get as far as saying that FirstOrDefault() is a code smell not because there is something wrong with it but because it’s being used way too often. This blog post explores the topic in details. IMO most of the times SingleOrDefault() is a much better alternative so watch out for this mistake and make sure you use the most appropriate method that clearly represents your contract and expectations.

I'm asked this question very frequently, if it's smart to use "Share project..." if a eclipse project has been disconnected from it SVN counterpart in the repository. So, I append my answer to this thread.

The SVN-Team option "Share project ..." is totally fine for projects that exist in SVN and in your Eclipse workspace, even if the Eclipse project is missing the hidden .svn configuration. You can still connect them. Eclipse SVN-implementation (Subclipse/Subversive) will verify if the provided SVN http(s) source is populated. If yes, all existing files will be copied and linked (checked out in SVN terms) to your very personal Eclipse workspace.

Word of caution:

• Do a backup if you depend on you local files. The SVN implementation may vary its behaviour with every release.
• If you have multiple projects encapsulated within each other, make sure you point the SVN path to the correct local path.

regards, Feder

I disagree with the posts saying that you must remove any __init__.py files. What you must instead do is alter the sys.path.

Run an experiment where you print sys.path when running the code normally. Then print sys.path while running the code via pytest. I think you will find that there is a difference between these two paths, hence why pytest breaks.

To fix this, insert the path from the first experiment at the 0th index of the second.

Let '/usr/exampleUser/Documents/foo' be the first element of print(sys.path) for experiment 1.

Below is code that should fix your issue:

import sys sys.path[0] = '/usr/exampleUser/Documents/foo'

Put this at the top of your file, before your actual import statement.

Source: I was dealing with this myself and the above process solved it.

This has really puzzled me for a while but this is what I found in the end.

When you call, sc.close() in first method, it not only closes your scanner but closes your System.in input stream as well. You can verify it by printing its status at very top of the second method as :

    System.out.println(System.in.available());

So, now when you re-instantiate, Scanner in second method, it doesn't find any open System.in stream and hence the exception.

I doubt if there is any way out to reopen System.in because:

public void close() throws IOException --> Closes this input stream and releases any system resources associated with this stream. The general contract of close is that it closes the input stream. A closed stream cannot perform input operations and **cannot be reopened.**

The only good solution for your problem is to initiate the Scanner in your main method, pass that as argument in your two methods, and close it again in your main method e.g.:

main method related code block:

Scanner scanner = new Scanner(System.in);  

// Ask users for quantities 
PromptCustomerQty(customer, ProductList, scanner );

// Ask user for payment method
PromptCustomerPayment(customer, scanner );

//close the scanner 
scanner.close();

Your Methods:

 public static void PromptCustomerQty(Customer customer, 
                             ArrayList<Product> ProductList, Scanner scanner) {

    // no more scanner instantiation
    ...
    // no more scanner close
 }


 public static void PromptCustomerPayment (Customer customer, Scanner sc) {

    // no more scanner instantiation
    ...
    // no more scanner close
 }

Hope this gives you some insight about the failure and possible resolution.

You want to use String.Replace to remove a character.

s = s.Replace("\n", String.Empty);
s = s.Replace("\r", String.Empty);
s = s.Replace("\t", String.Empty);

Note that String.Trim(params char[] trimChars) only removes leading and trailing characters in trimChars from the instance invoked on.

You could make an extension method, which avoids the performance problems of the above of making lots of temporary strings:

static string RemoveChars(this string s, params char[] removeChars) {
    Contract.Requires<ArgumentNullException>(s != null);
    Contract.Requires<ArgumentNullException>(removeChars != null);
    var sb = new StringBuilder(s.Length);
    foreach(char c in s) { 
        if(!removeChars.Contains(c)) {
            sb.Append(c);
        }
    }
    return sb.ToString();
}

function getDefaultDate(curDate){
var dt = new Date(curDate);`enter code here`
var date = dt.getDate();
var month = dt.getMonth();
var year = dt.getFullYear();
if (month.toString().length == 1) {
    month = "0" + month
}
if (date.toString().length == 1) {
    date = "0" + date
}
return year.toString() + "-" + month.toString() + "-" + date.toString();
}

In function pass your date string.

You've got several options how to do this, either:

• urlencode() or rawurlencode() - functions designed to encode URLs for http protocol
• str_replace() - "heavy machinery" string replace
• strtr() - would have better performance than str_replace() when replacing multiple characters
• preg_replace() use regular expressions (perl compatible)

strtr()

Assuming that you want to replace "\t" and " " with "%20":

$replace_pairs = array(
  "\t" => '%20',
  " " => '%20',
);
return strtr( $text, $replace_pairs)

preg_replace()

You've got few options here, either replacing just space ~ ~, again replacing space and tab ~[ \t]~ or all kinds of spaces ~\s~:

return preg_replace( '~\s~', '%20', $text);

Or when you need to replace string like this "\t \t \t \t" with just one %20:

return preg_replace( '~\s+~', '%20', $text);

_{I assumed that you really want to use manual string replacement and handle more types of whitespaces such as non breakable space ( )}

To ignore this in a gradle build add this to the android section of your build file:

lintOptions {
   disable 'MissingTranslation'
}

On Linux Fedora30 several versions of the full java JDK are available, specifically package names:

java-1.8.0-openjdk-devel.x86_64 
java-11-openjdk-devel.x86_64

Once installed, they are found in: /usr/lib/jvm

To select the location/directory of a full development JDK (which is different from the simpler runtime only JRE) look for entries:

ls -ld java*openjdk*

Here are two good choices, which are links to specific versions, where you will have to select the version:

/usr/lib/jvm/java-1.8.0-openjdk

A quick gotcha that I learned the hard way (basically spending 4 hours on Google), you can use PageMethods in your ASPX file to return JSON (with the [ScriptMethod()] marker) for a static method, however if you decide to move your static methods to an asmx file, it cannot be a static method.

Also, you need to tell the web service Content-Type: application/json in order to get JSON back from the call (I'm using jQuery and the 3 Mistakes To Avoid When Using jQuery article was very enlightening - its from the same website mentioned in another answer here).

The above solutions work fine for most cases. However, if you also need to remove all traces of that file (ie sensitive data such as passwords), you will also want to remove it from your entire commit history, as the file could still be retrieved from there.

Here is a solution that removes all traces of the file from your entire commit history, as though it never existed, yet keeps the file in place on your system.

https://help.github.com/articles/remove-sensitive-data/

You can actually skip to step 3 if you are in your local git repository, and don't need to perform a dry run. In my case, I only needed steps 3 and 6, as I had already created my .gitignore file, and was in the repository I wanted to work on.

To see your changes, you may need to go to the GitHub root of your repository and refresh the page. Then navigate through the links to get to an old commit that once had the file, to see that it has now been removed. For me, simply refreshing the old commit page did not show the change.

It looked intimidating at first, but really, was easy and worked like a charm ! :-)

You are using this :

mysql_fetch_array($result)

To get the error you're getting, it means that $result is not a resource.

In your code, $result is obtained this way :

$result = mysql_query("SELECT * FROM student WHERE IDNO=".$_GET['id']);

If the SQL query fails, $result will not be a resource, but a boolean -- see mysql_query.

I suppose there's an error in your SQL query -- so it fails, mysql_query returns a boolean, and not a resource, and mysql_fetch_array cannot work on that.

You should check if the SQL query returns a result or not :

$result = mysql_query("SELECT * FROM student WHERE IDNO=".$_GET['id']);
if ($result !== false) {
    // use $result
} else {
    // an error has occured
    echo mysql_error();
    die;    // note : echoing the error message and dying 
            // is OK while developping, but not in production !
}

With that, you should get a message that indicates the error that occured while executing your query -- this should help figure out what the problem is ;-)

Also, you should escape the data you're putting in your SQL query, to avoid SQL injections !

For example, here, you should make sure that $_GET['id'] contains nothing else than an integer, using something like this :

$result = mysql_query("SELECT * FROM student WHERE IDNO=" . intval($_GET['id']));

Or you should check this before trying to execute the query, to display a nicer error message to the user.

Take a look at SortedDictionary, there's even a constructor overload so you can pass in your own IComparable for the comparisons.

With Font Awesome icons:

<!-- Controls -->
<a class="carousel-control-prev" href="#carousel-example-generic" role="button" data-slide="prev">
  <span class="fa fa-chevron-left fa-lg" style="color:red;"></span>
  <span class="sr-only">Previous</span>
</a>
<a class="carousel-control-next" href="#carousel-example-generic" role="button" data-slide="next">
  <span class="fa fa-chevron-right fa-lg" style="color:red;"></span>
  <span class="sr-only">Next</span>
</a>

white-space: nowrap is the correct solution but it will prevent any break in a line. If you only want to prevent line breaks between two elements it gets a bit more complicated:

<p>
    <span class="text">Some text</span>
    <span class="icon"></span>
</p>

To prevent breaks between the spans but to allow breaks between "Some" and "text" can be done by:

p {
    white-space: nowrap;
}

.text {
    white-space: normal;
}

That's good enough for Firefox. In Chrome you additionally need to replace the whitespace between the spans with an  . (Removing the whitespace doesn't work.)

You can do following

Update 2016-06-27: instead of using Observables, use either

• a BehaviorSubject, as recommended by @Abdulrahman in a comment, or
• a ReplaySubject, as recommended by @Jason Goemaat in a comment

A Subject is both an Observable (so we can subscribe() to it) and an Observer (so we can call next() on it to emit a new value). We exploit this feature. A Subject allows values to be multicast to many Observers. We don't exploit this feature (we only have one Observer).

BehaviorSubject is a variant of Subject. It has the notion of "the current value". We exploit this: whenever we create an ObservingComponent, it gets the current navigation item value from the BehaviorSubject automatically.

The code below and the plunker use BehaviorSubject.

ReplaySubject is another variant of Subject. If you want to wait until a value is actually produced, use ReplaySubject(1). Whereas a BehaviorSubject requires an initial value (which will be provided immediately), ReplaySubject does not. ReplaySubject will always provide the most recent value, but since it does not have a required initial value, the service can do some async operation before returning it's first value. It will still fire immediately on subsequent calls with the most recent value. If you just want one value, use first() on the subscription. You do not have to unsubscribe if you use first().

import {Injectable}      from '@angular/core'
import {BehaviorSubject} from 'rxjs/BehaviorSubject';

@Injectable()
export class NavService {
  // Observable navItem source
  private _navItemSource = new BehaviorSubject<number>(0);
  // Observable navItem stream
  navItem$ = this._navItemSource.asObservable();
  // service command
  changeNav(number) {
    this._navItemSource.next(number);
  }
}

import {Component}    from '@angular/core';
import {NavService}   from './nav.service';
import {Subscription} from 'rxjs/Subscription';

@Component({
  selector: 'obs-comp',
  template: `obs component, item: {{item}}`
})
export class ObservingComponent {
  item: number;
  subscription:Subscription;
  constructor(private _navService:NavService) {}
  ngOnInit() {
    this.subscription = this._navService.navItem$
       .subscribe(item => this.item = item)
  }
  ngOnDestroy() {
    // prevent memory leak when component is destroyed
    this.subscription.unsubscribe();
  }
}

@Component({
  selector: 'my-nav',
  template:`
    <div class="nav-item" (click)="selectedNavItem(1)">nav 1 (click me)</div>
    <div class="nav-item" (click)="selectedNavItem(2)">nav 2 (click me)</div>`
})
export class Navigation {
  item = 1;
  constructor(private _navService:NavService) {}
  selectedNavItem(item: number) {
    console.log('selected nav item ' + item);
    this._navService.changeNav(item);
  }

Original answer that uses an Observable: (it requires more code and logic than using a BehaviorSubject, so I don't recommend it, but it may be instructive)

So, here's an implementation that uses an Observable instead of an EventEmitter. Unlike my EventEmitter implementation, this implementation also stores the currently selected navItem in the service, so that when an observing component is created, it can retrieve the current value via API call navItem(), and then be notified of changes via the navChange$ Observable.

import {Observable} from 'rxjs/Observable';
import 'rxjs/add/operator/share';
import {Observer} from 'rxjs/Observer';

export class NavService {
  private _navItem = 0;
  navChange$: Observable<number>;
  private _observer: Observer;
  constructor() {
    this.navChange$ = new Observable(observer =>
      this._observer = observer).share();
    // share() allows multiple subscribers
  }
  changeNav(number) {
    this._navItem = number;
    this._observer.next(number);
  }
  navItem() {
    return this._navItem;
  }
}

@Component({
  selector: 'obs-comp',
  template: `obs component, item: {{item}}`
})
export class ObservingComponent {
  item: number;
  subscription: any;
  constructor(private _navService:NavService) {}
  ngOnInit() {
    this.item = this._navService.navItem();
    this.subscription = this._navService.navChange$.subscribe(
      item => this.selectedNavItem(item));
  }
  selectedNavItem(item: number) {
    this.item = item;
  }
  ngOnDestroy() {
    this.subscription.unsubscribe();
  }
}

@Component({
  selector: 'my-nav',
  template:`
    <div class="nav-item" (click)="selectedNavItem(1)">nav 1 (click me)</div>
    <div class="nav-item" (click)="selectedNavItem(2)">nav 2 (click me)</div>
  `,
})
export class Navigation {
  item:number;
  constructor(private _navService:NavService) {}
  selectedNavItem(item: number) {
    console.log('selected nav item ' + item);
    this._navService.changeNav(item);
  }
}

See also the Component Interaction Cookbook example, which uses a Subject in addition to observables. Although the example is "parent and children communication," the same technique is applicable for unrelated components.

I use hydra package to control font increase/decrease contiguously by pressing f2 + + + +/f2 - - - -, which means that press f2 once, and then using +/- to control only, and restore default font size by f2 0. Because i have keypad, so I also bind keypad to the font setting.

(defhydra hydra-zoom (global-map "<f2>")
  "zoom"
  ("<kp-add>" text-scale-increase "in")
  ("+" text-scale-increase "in")
  ("-" text-scale-decrease "out")
  ("<kp-subtract>" text-scale-decrease "out")
  ("0" (text-scale-set 0) "reset")
  ("<kp-0>" (text-scale-set 0) "reset"))

And modern editor mouse control functionality supported by below key bindings, press control + mouse wheel to increase/decrease font.

(global-set-key (kbd "<C-wheel-up>") 'text-scale-increase)
(global-set-key (kbd "<C-wheel-down>") 'text-scale-decrease)

Run the following command, replacing PATH-TO-YOUR-FILE-WITH-SENSITIVE-DATA with the path to the file you want to remove, not just its filename. These arguments will:

1. Force Git to process, but not check out, the entire history of every branch and tag
2. Remove the specified file, as well as any empty commits generated as a result
3. Overwrite your existing tags

git filter-branch --force --index-filter "git rm --cached --ignore-unmatch PATH-TO-YOUR-FILE-WITH-SENSITIVE-DATA" --prune-empty --tag-name-filter cat -- --all

This will forcefully remove all references to the files from the active history of the repo.

Next step, to perform a GC cycle to force all references to the file to be expired and purged from the pack file. Nothing needs to be replaced in these commands.

git update-ref -d refs/original/refs/remotes/origin/master
git for-each-ref --format='delete %(refname)' refs/original | git update-ref --stdin
git reflog expire --expire=now --all
git gc --aggressive --prune=now

If you really need to be sure that now() has the same value you can run two queries (that will answer to your second question too, in that case you are asking to update last_monitor = to last_update but last_update hasn't been updated yet)

you could do something like:

mysql> update table set last_update=now() where id=1;
mysql> update table set last_monitor = last_update where id=1;

anyway I think that mysql is clever enough to ask for now() only once per query.

You can still use the answer provided using Toolbar.inflateMenu even while using setSupportActionBar(toolbar).

I had a scenario where I had to move toolbar setup functionality into a separate class outside of activity which didn't by-itself know of the event onCreateOptionsMenu.

So, to implement this, all I had to do was wait for Toolbar to be drawn before calling inflateMenu by doing the following:

toolbar.post {
    toolbar.inflateMenu(R.menu.my_menu)
}

Might not be considered very clean but still gets the job done.

To avoid try catch, use:

String s = "some text here";
byte[] b = s.getBytes(StandardCharsets.UTF_8);
System.out.println(b.length);

For me the solution was fixing a syntax error:

removing a unwanted semi colon in the angular.module function

Or, in order to avoid modifying slowFunc (say you don't have access to the source code for instance):

var source = new CancellationTokenSource(); //original code
source.Token.Register(CancelNotification); //original code
source.CancelAfter(TimeSpan.FromSeconds(1)); //original code
var completionSource = new TaskCompletionSource<object>(); //New code
source.Token.Register(() => completionSource.TrySetCanceled()); //New code
var task = Task<int>.Factory.StartNew(() => slowFunc(1, 2), source.Token); //original code

//original code: await task;  
await Task.WhenAny(task, completionSource.Task); //New code

You can also use nice extension methods from https://github.com/StephenCleary/AsyncEx and have it looks as simple as:

await Task.WhenAny(task, source.Token.AsTask());

preg_match_all('/\".*?\"/i', $string, $matches);
foreach ($matches[0] as $i => $match) $matches[$i] = trim($match, '"');

Bernstein has the method, use the Eclipse tool, "Rename Application Package", you may have to do some clean-up even after the fact. Also, Eclipse sometimes loses track of things when you make changes to a project. You may have to use the "Clean Project" tool (under the "Project" menu.) If that doesn't work, you may have to close and restart Eclipse. Voo-doo solutions, but Eclipse can be that way.

"\\s+" should do the trick

echo "this is the body" | mail -s "this is the subject" "to@address"

You need to repartition the Dataframe in a single partition and then define the format, path and other parameter to the file in Unix file system format and here you go,

df.repartition(1).write.format('com.databricks.spark.csv').save("/path/to/file/myfile.csv",header = 'true')

Read more about the repartition function Read more about the save function

However, repartition is a costly function and toPandas() is worst. Try using .coalesce(1) instead of .repartition(1) in previous syntax for better performance.

Read more on repartition vs coalesce functions.

I looked to MS to find the answers. The first solution assumes the user account running the application process has access to the shared folder or drive (Same domain). Make sure your DNS is resolved or try using IP address. Simply do the following:

 DirectoryInfo di = new DirectoryInfo(PATH);
 var files = di.EnumerateFiles("*.*", SearchOption.AllDirectories);

If you want across different domains .NET 2.0 with credentials follow this model:

WebRequest req = FileWebRequest.Create(new Uri(@"\\<server Name>\Dir\test.txt"));

        req.Credentials = new NetworkCredential(@"<Domain>\<User>", "<Password>");
        req.PreAuthenticate = true;

        WebResponse d = req.GetResponse();
        FileStream fs = File.Create("test.txt");

        // here you can check that the cast was successful if you want. 
        fs = d.GetResponseStream() as FileStream;
        fs.Close();

I like to add one that also works with dynamic javascript DOM creation like D3 where it is impossible to add:

//.attr(function(){if(condition){"readonly"]else{""}) //INCORRECT CODE !

to prevent actions on a HTML input DOM element add readonly to class:

var d = document.getElementById("div1");
d.className += " readonly";

OR in D3:

 .classed("readonly", function(){
   if(condition){return true}else{return false}
 })

AND add to CSS or less:

.readonly {
  pointer-events: none;
}

the nice thing about this solution is that you can dynamically turn it on and of in a function so it can be integrated in for example D3 at creation time (not possible with the single "readonly" attribute).

to remove the element from class:

document.getElementById("MyID").className =
  document.getElementById("MyID").className.replace(/\breadonly\b/,'');

or use Jquery:

$( "div" ).removeClass( "readonly" )

or toggle the class:

$( "div" ).toggleClass( "readonly", addOrRemove );

Just to be complete, good luck =^)

alternative solution for this with using many infowindows: save prev opened infowindow in a variable and then close it when new window opened

var prev_infowindow =false; 
...
base.attachInfo = function(marker, i){
    var infowindow = new google.maps.InfoWindow({
        content: 'yourmarkerinfocontent'
    });

    google.maps.event.addListener(marker, 'click', function(){
        if( prev_infowindow ) {
           prev_infowindow.close();
        }

        prev_infowindow = infowindow;
        infowindow.open(base.map, marker);
    });
}

Tracemalloc module was integrated as a built-in module starting from Python 3.4, and appearently, it's also available for prior versions of Python as a third-party library (haven't tested it though).

This module is able to output the precise files and lines that allocated the most memory. IMHO, this information is infinitly more valuable than the number of allocated instances for each type (which ends up being a lot of tuples 99% of the time, which is a clue, but barely helps in most cases).

I recommend you use tracemalloc in combination with pyrasite. 9 times out of 10, running the top 10 snippet in a pyrasite-shell will give you enough information and hints to to fix the leak within 10 minutes. Yet, if you're still unable to find the leak cause, pyrasite-shell in combination with the other tools mentioned in this thread will probably give you some more hints too. You should also take a look on all the extra helpers provided by pyrasite (such as the memory viewer).

Swift 4:

// add 5 minutes to date

let date = startDate.addingTimeInterval(TimeInterval(5.0 * 60.0))

// subtract 5 minutes from date

let date = startDate.addingTimeInterval(TimeInterval(-5.0 * 60.0))

Swift 5.1:

// subtract 5 minutes from date
transportationFromDate.addTimeInterval(TimeInterval(-5.0 * 60.0))

I can find following ways to do.

private static final String fileName = "C:/Input.txt";

public static void main(String[] args) throws IOException {
    Stream<String> lines = Files.lines(Paths.get(fileName));
    lines.toArray(String[]::new);

    List<String> readAllLines = Files.readAllLines(Paths.get(fileName));
    readAllLines.forEach(s -> System.out.println(s));

    File file = new File(fileName);
    Scanner scanner = new Scanner(file);
    while (scanner.hasNext()) {
        System.out.println(scanner.next());
    }

I've always thought that DLLs and shared objects are just different terms for the same thing - Windows calls them DLLs, while on UNIX systems they're shared objects, with the general term - dynamically linked library - covering both (even the function to open a .so on UNIX is called dlopen() after 'dynamic library').

They are indeed only linked at application startup, however your notion of verification against the header file is incorrect. The header file defines prototypes which are required in order to compile the code which uses the library, but at link time the linker looks inside the library itself to make sure the functions it needs are actually there. The linker has to find the function bodies somewhere at link time or it'll raise an error. It ALSO does that at runtime, because as you rightly point out the library itself might have changed since the program was compiled. This is why ABI stability is so important in platform libraries, as the ABI changing is what breaks existing programs compiled against older versions.

Static libraries are just bundles of object files straight out of the compiler, just like the ones that you are building yourself as part of your project's compilation, so they get pulled in and fed to the linker in exactly the same way, and unused bits are dropped in exactly the same way.

The class pull-right is still there in Bootstrap 3 See the 'helper classes' here

pull-right is defined by

.pull-right {
  float: right !important;
}

without more info on styles and content, it's difficult to say.

It definitely pulls right in this JSBIN when the page is wider than 990px - which is when the col-md styling kicks in, Bootstrap 3 being mobile first and all.

Bootstrap 4

Note that for Bootstrap 4 .pull-right has been replaced with .float-right https://www.geeksforgeeks.org/pull-left-and-pull-right-classes-in-bootstrap-4/#:~:text=pull%2Dright%20classes%20have%20been,based%20on%20the%20Bootstrap%20Grid.

For me, the problem resolves after I changed:

to

My work is based on Jquery 2.2.4, and I'm running my development on the latest Xampp and Chrome.

Are you hosting the site on iis? if so make sure the account your website runs under has access to local file system?

Straight from msdn .....

The Network Service account has Read and Execute permissions on the IIS server root folder by default. The IIS server root folder is named Wwwroot. This means that an ASP.NET application deployed inside the root folder already has Read and Execute permissions to its application folders. However, if your ASP.NET application needs to use files or folders in other locations, you must specifically enable access.

To provide access to an ASP.NET application running as Network Service, you must grant access to the Network Service account.

To grant read, write, and modify permissions to a specific file

• In Windows Explorer, locate and select the required file.
• Right-click the file, and then click Properties.
• In the Properties dialog box, click the Security tab.
• On the Security tab, examine the list of users. If the Network Service
• account is not listed, add it.
• In the Properties dialog box, click the Network Service user name, and in the Permissions for NETWORK SERVICE section, select the Read, Write, and Modify permissions.
• Click Apply, and then click OK.

I'm assuming the contents of src/main/resources/ is copied to WEB-INF/classes/ inside your .war at build time. If that is the case you can just do (substituting real values for the classname and the path being loaded).

URL sqlScriptUrl = MyServletContextListener.class
                       .getClassLoader().getResource("sql/script.sql");

Looking at the "effective POM" will probably help too. For instance, if you wanted to know what the path is for ${project.build.sourceDirectory}

you would find the related XML in the effective POM, such as: <project> <build> <sourceDirectory>/my/path</sourceDirectory>

Also helpful - you can do a real time evaluation of properties via the command line execution of mvn help:evaluate while in the same dir as the POM.

If you really want to match only the dot, then StringComparison.Ordinal would be fastest, as there is no case-difference.

"Ordinal" doesn't use culture and/or casing rules that are not applicable anyway on a symbol like a ..

There are two ways to achieve this.

1- As already proposed u can set the background of your spinner as custom 9 patch Image with all the adjustments made into it .

android:background="@drawable/btn_dropdown" 
android:clickable="true"
android:dropDownVerticalOffset="-10dip"
android:dropDownHorizontalOffset="0dip"
android:gravity="center"

If you want your Spinner to show With various different background colors i would recommend making the drop down image transparent, & loading that spinner in a relative layout with your color set in.

btn _dropdown is as:

<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item
    android:state_window_focused="false" android:state_enabled="true"
    android:drawable="@drawable/spinner_default" />
<item
    android:state_window_focused="false" android:state_enabled="false"
    android:drawable="@drawable/spinner_default" />
<item
    android:state_pressed="true"
    android:drawable="@drawable/spinner_pressed" />
<item
    android:state_focused="true" android:state_enabled="true"
    android:drawable="@drawable/spinner_pressed" />
<item
    android:state_enabled="true"
    android:drawable="@drawable/spinner_default" />
<item
    android:state_focused="true"
    android:drawable="@drawable/spinner_pressed" />
<item
    android:drawable="@drawable/spinner_default" />
</selector>

where the various states of pngwould define your various States of spinner seleti

In [3]: df[df['ids'].str.contains("ball")]
Out[3]:
     ids  vals
0  aball     1
1  bball     2
3  fball     4

One of the benefits is you can use it in multiple views and have a consistent label text. It is also used by asp.net MVC scaffolding to generate the labels text and makes it easier to generate meaningful text

[Display(Name = "Wild and Crazy")]
public string WildAndCrazyProperty { get; set; }

"Wild and Crazy" shows up consistently wherever you use the property in your application.

Sometimes this is not flexible as you might want to change the text in some view. In that case, you will have to use custom markup like in your second example

This is a highly inefficient way of doing it. You can use the merge statement and then there's no need for cursors, looping or (if you can do without) PL/SQL.

MERGE INTO studLoad l
USING ( SELECT studId, studName FROM student ) s
ON (l.studId = s.studId)
WHEN MATCHED THEN
  UPDATE SET l.studName = s.studName
   WHERE l.studName != s.studName
WHEN NOT MATCHED THEN 
INSERT (l.studID, l.studName)
VALUES (s.studId, s.studName)

Make sure you commit, once completed, in order to be able to see this in the database.

To actually answer your question I would do it something like as follows. This has the benefit of doing most of the work in SQL and only updating based on the rowid, a unique address in the table.

It declares a type, which you place the data within in bulk, 10,000 rows at a time. Then processes these rows individually.

However, as I say this will not be as efficient as merge.

declare

   cursor c_data is
    select b.rowid as rid, a.studId, a.studName
      from student a
      left outer join studLoad b
        on a.studId = b.studId
       and a.studName <> b.studName
           ;

   type t__data is table of c_data%rowtype index by binary_integer;
   t_data t__data;

begin

   open c_data;
   loop
      fetch c_data bulk collect into t_data limit 10000;

      exit when t_data.count = 0;

      for idx in t_data.first .. t_data.last loop
         if t_data(idx).rid is null then
            insert into studLoad (studId, studName)
            values (t_data(idx).studId, t_data(idx).studName);
         else
            update studLoad
               set studName = t_data(idx).studName
             where rowid = t_data(idx).rid
                   ;
         end if;
      end loop;

   end loop;
   close c_data;

end;
/

changing these functions will allow you to log the listeners added:

EventTarget.prototype.addEventListener
EventTarget.prototype.attachEvent
EventTarget.prototype.removeEventListener
EventTarget.prototype.detachEvent

read the rest of the listeners with

console.log(someElement.onclick);
console.log(someElement.getAttribute("onclick"));

An additional option is to go to your build folder and use the command ccmake .

This is like the GUI but terminal based. This obviously won't help with an installation script but at least it can be run without a UI.

The one warning I have is it won't let you generate sometimes when you have warnings. if that is the case, exit the interface and call cmake .

When starting the JVM, two parameters can be adjusted to suit your memory needs :

-Xms<size>

specifies the initial Java heap size and

-Xmx<size>

the maximum Java heap size.

This started happening to my site after I enabled namespace and custom Open Graph actions and objects. Once you enable it, you lose support for standard object types such as bar, or in my case article. (or it's possible Facebook may have deprecated certain types, I'm not 100% sure) When no supported type is specified, Facebook defaults to website.

To fix this what you need to do is go into your app dashboard, select your app, then go to the Open Graph section. Under "Object Types", define your own types, such as "bar."

Next you will have to change your meta tags to look like this:

<meta property="og:type" content="your_namespace:your_object_type" /> 

If you click on "Get Code" next to the object type in the dashboard, Facebook will provide you with an example of meta tags to use.

After trying all of the answers mentioned most if not all of them had edge cases and couldn't completely support my needs.

I started exploring how php does it and came across the php.js lib which replicates the strip_tags method here: http://phpjs.org/functions/strip_tags/

you could do this, if you want to use the old syntax (or don't want to rewrite every template)

@for $i from 1 through $grid-columns {
  @include media-breakpoint-up(xs) {
    .col-xs-#{$i} {
      @include make-col-ready();
      @include make-col($i);
    }
  }
}

Your main doesn't know about writeFile() and can't call it.

Move writefile to be before main, or declare a function prototype int writeFile(); before main.

Try doing it like this.

User::where('email', $userEmail)
       ->update([
           'member_type' => $plan
        ]);

There are many solutions to this problem as provided by above experts. Below solution can be use which will not block the page rendering or not even re-trigger it.

In Pure Javascript:

window.addEventListener('load', (
    function () {
        document.getElementById('copyright-year').appendChild(
            document.createTextNode(
                new Date().getFullYear()
            )
        );
    }
));

<div> &copy; <span id="copyright-year"></span></div>

In jQuery:

$(document).ready(function() {
  document.getElementById('copyright-year').appendChild(
    document.createTextNode(
      new Date().getFullYear()
    )
  );
});

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div> &copy; <span id="copyright-year"></span></div>

This line is your problem:

litersOfPetrol = Float.parseFloat(df.format(litersOfPetrol));

There you formatted your float to string as you wanted, but but then that string got transformed again to a float, and then what you printed in stdout was your float that got a standard formatting. Take a look at this code

import java.text.DecimalFormat;

String stringLitersOfPetrol = "123.00";
System.out.println("string liters of petrol putting in preferences is "+stringLitersOfPetrol);
Float litersOfPetrol=Float.parseFloat(stringLitersOfPetrol);
DecimalFormat df = new DecimalFormat("0.00");
df.setMaximumFractionDigits(2);
stringLitersOfPetrol = df.format(litersOfPetrol);
System.out.println("liters of petrol before putting in editor : "+stringLitersOfPetrol);

And by the way, when you want to use decimals, forget the existence of double and float as others suggested and just use BigDecimal object, it will save you a lot of headache.

I noticed this is an old post. However I just ran into the same problem and found a solution. A) Make sure you have the CPU/ABI is atom B)Ram is 2048 C)VM Heap is 256 D)Internal Storage is 200 E)Make sure to check the Use Host GPU F)Device is Nexus 5 (My personal choice) G)Android 4.4.2 API Level 19

If you want to use all stylesheet in your app just adds this line in application.html.erb. Insert it inside <head> tag

  <%= stylesheet_link_tag  controller.controller_name , media: 'all', 'data-turbolinks-track': 'reload' %>

Also, to specify the same class CSS on a different controller
Add this line in the body of application.html.erb

  <body class="<%= controller.controller_name %>-<%= controller.action_name %>">

So, now for example I would like to change the p tag in 'home' controller and 'index' action. Inside index.scss file adds.

.nameOfController-nameOfAction <tag> { }

 .home-index p {
        color:red !important;
      }

if you are in the main you can do:

return 0;  

or

exit(exit_code);

The exit code depends of the semantic of your code. 1 is error 0 e a normal exit.

In some other function of your program:

exit(exit_code)  

will exit the program.

Idempotence means that applying an operation once or applying it multiple times has the same effect.

Examples:

• Multiplication by zero. No matter how many times you do it, the result is still zero.
• Setting a boolean flag. No matter how many times you do it, the flag stays set.
• Deleting a row from a database with a given ID. If you try it again, the row is still gone.

For pure functions (functions with no side effects) then idempotency implies that f(x) = f(f(x)) = f(f(f(x))) = f(f(f(f(x)))) = ...... for all values of x

For functions with side effects, idempotency furthermore implies that no additional side effects will be caused after the first application. You can consider the state of the world to be an additional "hidden" parameter to the function if you like.

Note that in a world where you have concurrent actions going on, you may find that operations you thought were idempotent cease to be so (for example, another thread could unset the value of the boolean flag in the example above). Basically whenever you have concurrency and mutable state, you need to think much more carefully about idempotency.

Idempotency is often a useful property in building robust systems. For example, if there is a risk that you may receive a duplicate message from a third party, it is helpful to have the message handler act as an idempotent operation so that the message effect only happens once.

Summary

In context of deep learning the logits layer means the layer that feeds in to softmax (or other such normalization). The output of the softmax are the probabilities for the classification task and its input is logits layer. The logits layer typically produces values from -infinity to +infinity and the softmax layer transforms it to values from 0 to 1.

Historical Context

Where does this term comes from? In 1930s and 40s, several people were trying to adapt linear regression to the problem of predicting probabilities. However linear regression produces output from -infinity to +infinity while for probabilities our desired output is 0 to 1. One way to do this is by somehow mapping the probabilities 0 to 1 to -infinity to +infinity and then use linear regression as usual. One such mapping is cumulative normal distribution that was used by Chester Ittner Bliss in 1934 and he called this "probit" model, short for "probability unit". However this function is computationally expensive while lacking some of the desirable properties for multi-class classification. In 1944 Joseph Berkson used the function log(p/(1-p)) to do this mapping and called it logit, short for "logistic unit". The term logistic regression derived from this as well.

The Confusion

Unfortunately the term logits is abused in deep learning. From pure mathematical perspective logit is a function that performs above mapping. In deep learning people started calling the layer "logits layer" that feeds in to logit function. Then people started calling the output values of this layer "logit" creating the confusion with logit the function.

TensorFlow Code

Unfortunately TensorFlow code further adds in to confusion by names like tf.nn.softmax_cross_entropy_with_logits. What does logits mean here? It just means the input of the function is supposed to be the output of last neuron layer as described above. The _with_logits suffix is redundant, confusing and pointless. Functions should be named without regards to such very specific contexts because they are simply mathematical operations that can be performed on values derived from many other domains. In fact TensorFlow has another similar function sparse_softmax_cross_entropy where they fortunately forgot to add _with_logits suffix creating inconsistency and adding in to confusion. PyTorch on the other hand simply names its function without these kind of suffixes.

Reference

The Logit/Probit lecture slides is one of the best resource to understand logit. I have also updated Wikipedia article with some of above information.

@ImportanceOfBeingErnest 's answer is good if you only want to change the linewidth inside the legend box. But I think it is a bit more complex since you have to copy the handles before changing legend linewidth. Besides, it can not change the legend label fontsize. The following two methods can not only change the linewidth but also the legend label text font size in a more concise way.

Method 1

import numpy as np
import matplotlib.pyplot as plt

# make some data
x = np.linspace(0, 2*np.pi)

y1 = np.sin(x)
y2 = np.cos(x)

# plot sin(x) and cos(x)
fig = plt.figure()
ax  = fig.add_subplot(111)
ax.plot(x, y1, c='b', label='y1')
ax.plot(x, y2, c='r', label='y2')

leg = plt.legend()
# get the individual lines inside legend and set line width
for line in leg.get_lines():
    line.set_linewidth(4)
# get label texts inside legend and set font size
for text in leg.get_texts():
    text.set_fontsize('x-large')

plt.savefig('leg_example')
plt.show()

Method 2

import numpy as np
import matplotlib.pyplot as plt

# make some data
x = np.linspace(0, 2*np.pi)

y1 = np.sin(x)
y2 = np.cos(x)

# plot sin(x) and cos(x)
fig = plt.figure()
ax  = fig.add_subplot(111)
ax.plot(x, y1, c='b', label='y1')
ax.plot(x, y2, c='r', label='y2')

leg = plt.legend()
# get the lines and texts inside legend box
leg_lines = leg.get_lines()
leg_texts = leg.get_texts()
# bulk-set the properties of all lines and texts
plt.setp(leg_lines, linewidth=4)
plt.setp(leg_texts, fontsize='x-large')
plt.savefig('leg_example')
plt.show()

The above two methods produce the same output image:

In a GET request, the request parameters are taken from the query string (the data following the question mark on the URL). For example, the URL http://hostname.com?p1=v1&p2=v2 contains two request parameters - - p1 and p2. In a POST request, the request parameters are taken from both query string and the posted data which is encoded in the body of the request.

This example demonstrates how to include the value of a request parameter in the generated output:

Hello <b><%= request.getParameter("name") %></b>!

If the page was accessed with the URL:

http://hostname.com/mywebapp/mypage.jsp?name=John+Smith

the resulting output would be:

Hello <b>John Smith</b>!

If name is not specified on the query string, the output would be:

Hello <b>null</b>!

This example uses the value of a query parameter in a scriptlet:

<%
    if (request.getParameter("name") == null) {
        out.println("Please enter your name.");
    } else {
        out.println("Hello <b>"+request. getParameter("name")+"</b>!");
    }
%>

var objects={...}; this.getAllvalues = function () {
        var vls = [];
        for (var key in objects) {
            vls.push(objects[key]);
        }
        return vls;
    }

There is no way in Selenium to read the request or response headers. You could do it by instructing your browser to connect through a proxy that records this kind of information.

Setting the User Agent in Firefox

The usual way to change the user agent for Firefox is to set the variable "general.useragent.override" in your Firefox profile. Note that this is independent from Selenium.

You can direct Selenium to use a profile different from the default one, like this:

from selenium import webdriver
profile = webdriver.FirefoxProfile()
profile.set_preference("general.useragent.override", "whatever you want")
driver = webdriver.Firefox(profile)

Setting the User Agent in Chrome

With Chrome, what you want to do is use the user-agent command line option. Again, this is not a Selenium thing. You can invoke Chrome at the command line with chrome --user-agent=foo to set the agent to the value foo.

With Selenium you set it like this:

from selenium import webdriver
from selenium.webdriver.chrome.options import Options
opts = Options()
opts.add_argument("user-agent=whatever you want")

driver = webdriver.Chrome(chrome_options=opts)

Both methods above were tested and found to work. I don't know about other browsers.

Getting the User Agent

Selenium does not have methods to query the user agent from an instance of WebDriver. Even in the case of Firefox, you cannot discover the default user agent by checking what general.useragent.override would be if not set to a custom value. (This setting does not exist before it is set to some value.)

Once the browser is started, however, you can get the user agent by executing:

agent = driver.execute_script("return navigator.userAgent")

The agent variable will contain the user agent.

I had a similar error after php update. PHP fixed a security bug where o had rw permission to the socket file.

1. Open /etc/php5/fpm/pool.d/www.conf or /etc/php/7.0/fpm/pool.d/www.conf, depending on your version.

2. Uncomment all permission lines, like:

   listen.owner = www-data
   listen.group = www-data
   listen.mode = 0660
   

3. Restart fpm - sudo service php5-fpm restart or sudo service php7.0-fpm restart

Note: if your webserver runs as user other than www-data, you will need to update the www.conf file accordingly

Oracle has a different syntax for parameters than Sql-Server. So use : instead of @

using(var con=new OracleConnection(connectionString))
{
   con.open();
   var sql = "insert into users values (:id,:name,:surname,:username)";

   using(var cmd = new OracleCommand(sql,con)
   {
      OracleParameter[] parameters = new OracleParameter[] {
             new OracleParameter("id",1234),
             new OracleParameter("name","John"),
             new OracleParameter("surname","Doe"),
             new OracleParameter("username","johnd")
      };

      cmd.Parameters.AddRange(parameters);
      cmd.ExecuteNonQuery();
   }
}

When using named parameters in an OracleCommand you must precede the parameter name with a colon (:).

If you want to change icons' and texts' colors programmatically:

ColorStateList iconsColorStates = new ColorStateList(
            new int[][]{
                    new int[]{-android.R.attr.state_checked},
                    new int[]{android.R.attr.state_checked}
            },
            new int[]{
                    Color.parseColor("#123456"),
                    Color.parseColor("#654321")
            });

    ColorStateList textColorStates = new ColorStateList(
            new int[][]{
                    new int[]{-android.R.attr.state_checked},
                    new int[]{android.R.attr.state_checked}
            },
            new int[]{
                    Color.parseColor("#123456"),
                    Color.parseColor("#654321")
            });

    navigation.setItemIconTintList(iconsColorStates);
    navigation.setItemTextColor(textColorStates);

You can use jQuery Mobile vclick event:

Normalized event for handling touchend or mouse click events on touch devices.

$(document).ready(function(){
   $('.publications').vclick(function() {
       $('#filter_wrapper').show();
   });

$.each( { name: "John", lang: "JS" }, function(i, n){
    alert( "Name: " + i + ", Value: " + n );

This should do the trick:

models.DateTimeField(_("Date"), auto_now_add = True)

Here is my answer:

Brief: I was using typeorm as a ORM library. So, to set the query logging level I have used the following option instead of directly setting the logging option as false.

Solution: File name - ormconfig.ts

{
    'type': process.env.DB_DRIVER,
    'host': process.env.DB_HOST,
    'port': process.env.DB_PORT,
    'username': process.env.DB_USER,
    'password': process.env.DB_PASS,
    'database': process.env.DB_NAME,
    'migrations': [process.env.MIGRATIONS_ENTITIES],
    'synchronize': false,
    'logging': process.env.DB_QUERY_LEVEL,
    'entities': [
        process.env.ORM_ENTITIES
    ],
    'cli': {
        'migrationsDir': 'migrations'
     }
}

And, in the envrionment variable set the DB_QUERY_LEVEL as ["query", "error"].

Result: As a result it will log only when the query has error else it won't.

Here is how you can do it in Swift:

let vc = UIViewController()
self.presentViewController(vc, animated: true, completion: nil)

I made a legend by adding it to the figure, not to an axis (matplotlib 2.2.2). To remove it, I set the legends attribute of the figure to an empty list:

import matplotlib.pyplot as plt

fig = plt.figure()
ax1 = fig.add_subplot(111)
ax2 = ax1.twinx()

ax1.plot(range(10), range(10, 20), label='line 1')
ax2.plot(range(10), range(30, 20, -1), label='line 2')

fig.legend()

fig.legends = []

plt.show()

#include <bits/stdc++.h>                        // to include all libraries 
using namespace std; 
int main() 
{ 
double a,b;
cin>>a>>b;
double x=a/b;                                 //say we want to divide a/b                                 
cout<<fixed<<setprecision(10)<<x;             //for precision upto 10 digit 
return 0; 
} 

input: 1987 31

output: 662.3333333333 10 digits after decimal point

To contribute my 5 cents to the thorough explanation from Amadan.

Where classes are a description "of a type" in an abstract way. Objects are their realizations: the living breathing thing. In the object-orientated world there are principal ideas you can almost call the essence of everything. They are:

1. encapsulation (won't elaborate on this)
2. inheritance
3. polymorphism

Objects have one, or more characteristics (= Attributes) and behaviors (= Methods). The behavior mostly depends on the characteristics. Classes define what the behavior should accomplish in a general way, but as long as the class is not realized (instantiated) as an object it remains an abstract concept of a possibility. Let me illustrate with the help of "inheritance" and "polymorphism".

    class Human:
        gender
        nationality
        favorite_drink
        core_characteristic
        favorite_beverage
        name
        age

        def love    
        def drink
        def laugh
        def do_your_special_thing                

    class Americans(Humans)
        def drink(beverage):
            if beverage != favorite_drink: print "You call that a drink?"
            else: print "Great!" 

    class French(Humans)
        def drink(beverage, cheese):
            if beverage == favourite_drink and cheese == None: print "No cheese?" 
            elif beverage != favourite_drink and cheese == None: print "Révolution!"

    class Brazilian(Humans)
        def do_your_special_thing
            win_every_football_world_cup()

    class Germans(Humans)
        def drink(beverage):
            if favorite_drink != beverage: print "I need more beer"
            else: print "Lecker!" 

    class HighSchoolStudent(Americans):
        def __init__(self, name, age):
             self.name = name
             self.age = age

jeff = HighSchoolStudent(name, age):
hans = Germans()
ronaldo = Brazilian()
amelie = French()

for friends in [jeff, hans, ronaldo]:
    friends.laugh()
    friends.drink("cola")
    friends.do_your_special_thing()

print amelie.love(jeff)
>>> True
print ronaldo.love(hans)
>>> False

Some characteristics define human beings. But every nationality differs somewhat. So "national-types" are kinda Humans with extras. "Americans" are a type of "Humans " and inherit some abstract characteristics and behavior from the human type (base-class) : that's inheritance. So all Humans can laugh and drink, therefore all child-classes can also! Inheritance (2).

But because they are all of the same kind (Type/base-class : Humans) you can exchange them sometimes: see the for-loop at the end. But they will expose an individual characteristic, and thats Polymorphism (3).

So each human has a favorite_drink, but every nationality tend towards a special kind of drink. If you subclass a nationality from the type of Humans you can overwrite the inherited behavior as I have demonstrated above with the drink() Method. But that's still at the class-level and because of this it's still a generalization.

hans = German(favorite_drink = "Cola")

instantiates the class German and I "changed" a default characteristic at the beginning. (But if you call hans.drink('Milk') he would still print "I need more beer" - an obvious bug ... or maybe that's what i would call a feature if i would be a Employee of a bigger Company. ;-)! )

The characteristic of a type e.g. Germans (hans) are usually defined through the constructor (in python : __init__) at the moment of the instantiation. This is the point where you define a class to become an object. You could say breath life into an abstract concept (class) by filling it with individual characteristics and becoming an object.

But because every object is an instance of a class they share all some basic characteristic-types and some behavior. This is a major advantage of the object-orientated concept.

To protect the characteristics of each object you encapsulate them - means you try to couple behavior and characteristic and make it hard to manipulate it from outside the object. That's Encapsulation (1)

Although maven exec does the trick here, I found it pretty poor for a real test. While waiting for maven shell, and hoping this could help others, I finally came out to this repo mvnexec

Clone it, and symlink the script somewhere in your path. I use ~/bin/mvnexec, as I have ~/bin in my path. I think mvnexec is a good name for the script, but is up to you to change the symlink...

Launch it from the root of your project, where you can see src and target dirs.

The script search for classes with main method, offering a select to choose one (Example with mavenized JMeld project)

$ mvnexec 
 1) org.jmeld.ui.JMeldComponent
 2) org.jmeld.ui.text.FileDocument
 3) org.jmeld.JMeld
 4) org.jmeld.util.UIDefaultsPrint
 5) org.jmeld.util.PrintProperties
 6) org.jmeld.util.file.DirectoryDiff
 7) org.jmeld.util.file.VersionControlDiff
 8) org.jmeld.vc.svn.InfoCmd
 9) org.jmeld.vc.svn.DiffCmd
10) org.jmeld.vc.svn.BlameCmd
11) org.jmeld.vc.svn.LogCmd
12) org.jmeld.vc.svn.CatCmd
13) org.jmeld.vc.svn.StatusCmd
14) org.jmeld.vc.git.StatusCmd
15) org.jmeld.vc.hg.StatusCmd
16) org.jmeld.vc.bzr.StatusCmd
17) org.jmeld.Main
18) org.apache.commons.jrcs.tools.JDiff
#? 

If one is selected (typing number), you are prompt for arguments (you can avoid with mvnexec -P)

By default it compiles project every run. but you can avoid that using mvnexec -B

It allows to search only in test classes -M or --no-main, or only in main classes -T or --no-test. also has a filter by name option -f <whatever>

Hope this could save you some time, for me it does.

Your @JsonSubTypes declaration does not make sense: it needs to list implementation (sub-) classes, NOT the class itself (which would be pointless). So you need to modify that entry to list sub-class(es) there are; or use some other mechanism to register sub-classes (SimpleModule has something like addAbstractTypeMapping).

For TextView and it's descendants (e.g., Button) you can get the display size from the WindowManager and then set the TextView height to be some fraction of it:

Button btn = new Button (this);
android.view.Display display = ((android.view.WindowManager)getSystemService(Context.WINDOW_SERVICE)).getDefaultDisplay(); 
btn.setHeight((int)(display.getHeight()*0.68));

Nowadays, there is a simple way to do this : Object.values().

var myObj = {
    1: [1, 2, 3],
    2: [4, 5, 6]
};

console.log(Object.values(myObj));

Output:

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

This doesn't required jQuery, it's been defined in ECMAScript 2017.
It's supported by every modern browser (forget IE).

From $http.get docs, the second parameter is a configuration object:

get(url, [config]);

Shortcut method to perform GET request.

You may change your code to:

$http.get('accept.php', {
    params: {
        source: link, 
        category_id: category
    }
});

Or:

$http({
    url: 'accept.php', 
    method: 'GET',
    params: { 
        source: link, 
        category_id: category
    }
});

As a side note, since Angular 1.6: .success should not be used anymore, use .then instead:

$http.get('/url', config).then(successCallback, errorCallback);

ServicePointManager.ServerCertificateValidationCallback isn't supported in .Net Core.

Current situation is that it will be a a new ServerCertificateCustomValidationCallback method for the upcoming 4.1.* System.Net.Http contract (HttpClient). .NET Core team are finalizing the 4.1 contract now. You can read about this in here on github

You can try out the pre-release version of System.Net.Http 4.1 by using the sources directly here in CoreFx or on the MYGET feed: https://dotnet.myget.org/gallery/dotnet-core

I know this is an old thread, but has anyone checked if their Antivirus is blocking Win32API and Scripting on their systems? I have CylanceProtect installed on my office system and i found the same issues occurring as listed by others. This can be confirmed if you check the Windows Logs in Event Viewer.

A character set is a subset of all written glyphs. A character encoding specifies how those characters are mapped to numeric values. Some character encodings, like UTF-8 and UTF-16, can encode any character in the Universal Character Set. Others, like US-ASCII or ISO-8859-1 can only encode a small subset, since they use 7 and 8 bits per character, respectively. Because many standards specify both a character set and a character encoding, the term "character set" is often substituted freely for "character encoding".

A collation comprises rules that specify how characters can be compared for sorting. Collations rules can be locale-specific: the proper order of two characters varies from language to language.

Choosing a character set and collation comes down to whether your application is internationalized or not. If not, what locale are you targeting?

In order to choose what character set you want to support, you have to consider your application. If you are storing user-supplied input, it might be hard to foresee all the locales in which your software will eventually be used. To support them all, it might be best to support the UCS (Unicode) from the start. However, there is a cost to this; many western European characters will now require two bytes of storage per character instead of one.

Choosing the right collation can help performance if your database uses the collation to create an index, and later uses that index to provide sorted results. However, since collation rules are often locale-specific, that index will be worthless if you need to sort results according to the rules of another locale.

I have modified your code a little. Here's a working version (for me):

    <select name="dd1" id="dd1">
       <option value="none">None</option>
       <option value="o1">option 1</option>
       <option value="o2">option 2</option>
       <option value="o3">option 3</option>
    </select>  
    <div style="color:red;" id="msg_id"></div>

<script>
    $('#everything').submit(function(e){ 
        var department = $("#msg_id");
        var msg = "Please select Department";
            if ($('#dd1').val() == "") {
                department.append(msg);
                e.preventDefault();
                return false;
            }
        });
 </script>

UrlCreateFromPath to the rescue! Well, not entirely, as it doesn't support extended and UNC path formats, but that's not so hard to overcome:

public static Uri FileUrlFromPath(string path)
{
    const string prefix = @"\\";
    const string extended = @"\\?\";
    const string extendedUnc = @"\\?\UNC\";
    const string device = @"\\.\";
    const StringComparison comp = StringComparison.Ordinal;

    if(path.StartsWith(extendedUnc, comp))
    {
        path = prefix+path.Substring(extendedUnc.Length);
    }else if(path.StartsWith(extended, comp))
    {
        path = prefix+path.Substring(extended.Length);
    }else if(path.StartsWith(device, comp))
    {
        path = prefix+path.Substring(device.Length);
    }

    int len = 1;
    var buffer = new StringBuilder(len);
    int result = UrlCreateFromPath(path, buffer, ref len, 0);
    if(len == 1) Marshal.ThrowExceptionForHR(result);

    buffer.EnsureCapacity(len);
    result = UrlCreateFromPath(path, buffer, ref len, 0);
    if(result == 1) throw new ArgumentException("Argument is not a valid path.", "path");
    Marshal.ThrowExceptionForHR(result);
    return new Uri(buffer.ToString());
}

[DllImport("shlwapi.dll", CharSet=CharSet.Auto, SetLastError=true)]
static extern int UrlCreateFromPath(string path, StringBuilder url, ref int urlLength, int reserved);

In case the path starts with with a special prefix, it gets removed. Although the documentation doesn't mention it, the function outputs the length of the URL even if the buffer is smaller, so I first obtain the length and then allocate the buffer.

Some very interesting observation I had is that while "\\device\path" is correctly transformed to "file://device/path", specifically "\\localhost\path" is transformed to just "file:///path".

The WinApi function managed to encode special characters, but leaves Unicode-specific characters unencoded, unlike the Uri construtor. In that case, AbsoluteUri contains the properly encoded URL, while OriginalString can be used to retain the Unicode characters.

I'm not familiar with PHP, but I think String.split is Java equivalent to PHP explode. As for implode, standart library does not provide such functionality. You just iterate over your array and build string using StringBuilder/StringBuffer. Or you can try excellent Google Guava Splitter and Joiner or split/join methods from Apache Commons StringUtils.

To encode an array that contains special characters, ISO 8859-1 to UTF8. (If utf8_encode & utf8_decode is not what is working for you, this might be an option)

Everything that is in ISO-8859-1 should be converted to UTF8:

$utf8 = utf8_encode('? ??? ??? ????!'); //contains UTF8 & ISO 8859-1 characters;    
$iso88591 = mb_convert_encoding($utf8, 'ISO-8859-1', 'UTF-8');
$data = $iso88591;

Encode should work after this:

$encoded_data = json_encode($data);

Convert UTF-8 to & from ISO 8859-1

You can convert your empty row to integer value and check zero?.

"".to_i.zero? => true
nil.to_i.zero? => true

If you want to keep the innerHTML of the element and only strip the outermost tag, you can do this:

$(".contentToStrip").each(function(){
  $(this).replaceWith($(this).html());
});

v-bind and v-on are two frequently used directives in vuejs html template. So they provided a shorthand notation for the both of them as follows:

You can replace v-on: with @

v-on:click='someFunction'

as:

@click='someFunction'

Another example:

v-on:keyup='someKeyUpFunction'

as:

@keyup='someKeyUpFunction'

Similarly, v-bind with :

v-bind:href='var1'

Can be written as:

:href='var1'

Hope it helps!

You can't put a div directly inside a table, like this:

<!-- INVALID -->
<table>
  <div>
    Hello World
  </div>
</table>

Putting a div inside a td or th element is fine, however:

<!-- VALID -->
<table>
  <tr>
    <td>
      <div>
        Hello World
      </div>
    </td>
  </tr>
</table>

If you are using php you can add any function to your sql statement by using: SQLite3::createFunction. In PDO you can use PDO::sqliteCreateFunction and implement the preg_match function within your statement:

See how its done by Havalite (RegExp in SqLite using Php)

You will have to parse the content somehow ... I find using LINQ the most easy way to do it. Again, it all depends on your exact scenario. Here's a working example using LINQ to format an input XML string.

string FormatXml(string xml)
{
     try
     {
         XDocument doc = XDocument.Parse(xml);
         return doc.ToString();
     }
     catch (Exception)
     {
         // Handle and throw if fatal exception here; don't just ignore them
         return xml;
     }
 }

[using statements are ommitted for brevity]

There's an error in your code. You're using a mix of full syntax and shorthand notation on the background-image property.This is causing the no-repeat to be ignored, since it's not a valid value for the background-image property.

body{   
    background-position:center;
    background-image:url(../images/images2.jpg) no-repeat;
}

Should become one of the following:

body{
    background:url(../images/images2.jpg) center center no-repeat;
}

or

body
{
    background-image: url(path-to-file/img.jpg);
    background-repeat:no-repeat;
    background-position: center center;
}

Answer from different solutions to get Display Resolution

1. Get the scaling factor

2. Get Screen.PrimaryScreen.Bounds.Width and Screen.PrimaryScreen.Bounds.Height multiple by scaling factor result

   #region Display Resolution
   
    [DllImport("gdi32.dll", CharSet = CharSet.Auto, SetLastError = true, ExactSpelling = true)]
    public static extern int GetDeviceCaps(IntPtr hDC, int nIndex);
   
    public enum DeviceCap
    {
        VERTRES = 10,
        DESKTOPVERTRES = 117
    }
   
   
    public static double GetWindowsScreenScalingFactor(bool percentage = true)
    {
        //Create Graphics object from the current windows handle
        Graphics GraphicsObject = Graphics.FromHwnd(IntPtr.Zero);
        //Get Handle to the device context associated with this Graphics object
        IntPtr DeviceContextHandle = GraphicsObject.GetHdc();
        //Call GetDeviceCaps with the Handle to retrieve the Screen Height
        int LogicalScreenHeight = GetDeviceCaps(DeviceContextHandle, (int)DeviceCap.VERTRES);
        int PhysicalScreenHeight = GetDeviceCaps(DeviceContextHandle, (int)DeviceCap.DESKTOPVERTRES);
        //Divide the Screen Heights to get the scaling factor and round it to two decimals
        double ScreenScalingFactor = Math.Round(PhysicalScreenHeight / (double)LogicalScreenHeight, 2);
        //If requested as percentage - convert it
        if (percentage)
        {
            ScreenScalingFactor *= 100.0;
        }
        //Release the Handle and Dispose of the GraphicsObject object
        GraphicsObject.ReleaseHdc(DeviceContextHandle);
        GraphicsObject.Dispose();
        //Return the Scaling Factor
        return ScreenScalingFactor;
    }
   
    public static Size GetDisplayResolution()
    {
        var sf = GetWindowsScreenScalingFactor(false);
        var screenWidth = Screen.PrimaryScreen.Bounds.Width * sf;
        var screenHeight = Screen.PrimaryScreen.Bounds.Height * sf;
        return new Size((int)screenWidth, (int)screenHeight);
    }
   
    #endregion
   

to check display resolution

var size = GetDisplayResolution();
Console.WriteLine("Display Resoluton: " + size.Width + "x" + size.Height);

I know this is a very old question but it may be that you need to set the request headers. This solved it for me.

For example 'user-agent', 'accept' etc. here is an example with user-agent:

url = 'your-url-here'
headers = {'user-agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/86.0.4240.75 Safari/537.36'}
r = requests.get(url, headers=headers)

You can try this query in any given SQL Server database:

SELECT 
    name,
    create_date,
    modify_date
FROM sys.procedures
WHERE create_date = '20120927'  

which lists out the name, the creation and the last modification date - unfortunately, it doesn't record who created and/or modified the stored procedure in question.

You can try this website http://www.decompileandroid.com Just upload the .apk file and rest of it will be done by this site.

Firstly you need to install a SSH server in the images you wish to ssh-into. You can use a base image for all your container with the ssh server installed. Then you only have to run each container mapping the ssh port (default 22) to one to the host's ports (Remote Server in your image), using -p <hostPort>:<containerPort>. i.e:

docker run -p 52022:22 container1 
docker run -p 53022:22 container2

Then, if ports 52022 and 53022 of host's are accessible from outside, you can directly ssh to the containers using the ip of the host (Remote Server) specifying the port in ssh with -p <port>. I.e.:

ssh -p 52022 myuser@RemoteServer --> SSH to container1

ssh -p 53022 myuser@RemoteServer --> SSH to container2

The problem was the table width. I had used width: 100% for the table. The table columns are adjusted automatically after removing the width tag.

Python Extension. From the Python Docs:

The solution chosen by the Perl developers was to use (?...) as the extension syntax. ? immediately after a parenthesis was a syntax error because the ? would have nothing to repeat, so this didn’t introduce any compatibility problems. The characters immediately after the ? indicate what extension is being used, so (?=foo) is one thing (a positive lookahead assertion) and (?:foo) is something else (a non-capturing group containing the subexpression foo).

Python supports several of Perl’s extensions and adds an extension syntax to Perl’s extension syntax.If the first character after the question mark is a P, you know that it’s an extension that’s specific to Python

Remove the definitions and check if the conditional is on debug mode. You do not need to check if the directive is on release mode.

Something like this:

#if DEBUG
     Console.WriteLine("Mode=Debug"); 
#else
    Console.WriteLine("Mode=Release"); 
#endif

$("#employeeTable td").parent().remove();

This will remove all tr having td as child. i.e all rows except the header will be deleted.

It all depends how you use Java or C# enums. How you use it will dictate the solution you'll choose in Ruby.

Try the native Set type, for instance:

>> enum = Set['a', 'b', 'c']
=> #<Set: {"a", "b", "c"}>
>> enum.member? "b"
=> true
>> enum.member? "d"
=> false
>> enum.add? "b"
=> nil
>> enum.add? "d"
=> #<Set: {"a", "b", "c", "d"}>

Quite simply, a "callable" is something that can be called like a method. The built in function "callable()" will tell you whether something appears to be callable, as will checking for a call property. Functions are callable as are classes, class instances can be callable. See more about this here and here.

The solution seems to be to add multiple @font-face rules, for example:

@font-face {
    font-family: "DejaVu Sans";
    src: url("fonts/DejaVuSans.ttf");
}
@font-face {
    font-family: "DejaVu Sans";
    src: url("fonts/DejaVuSans-Bold.ttf");
    font-weight: bold;
}
@font-face {
    font-family: "DejaVu Sans";
    src: url("fonts/DejaVuSans-Oblique.ttf");
    font-style: italic, oblique;
}
@font-face {
    font-family: "DejaVu Sans";
    src: url("fonts/DejaVuSans-BoldOblique.ttf");
    font-weight: bold;
    font-style: italic, oblique;
}

By the way, it would seem Google Chrome doesn't know about the format("ttf") argument, so you might want to skip that.

(This answer was correct for the CSS 2 specification. CSS3 only allows for one font-style rather than a comma-separated list.)

This might work...

from p in db.products
    select new
    {
        Owner = (p.price > 0 ?
            from q in db.Users select q.Name :
            from r in db.ExternalUsers select r.Name)
    }

I haven't tested it but it should work.

public double incassoMargherita()
{
    double sum = 0;
    for(int i = 0; i < m.size(); i++)
    {
        sum = sum + m.get(i);
    }
    return sum;
}

My utils method for get current date time using Calendar when our minSdkVersion < 26.

fun Date.toString(format: String, locale: Locale = Locale.getDefault()): String {
    val formatter = SimpleDateFormat(format, locale)
    return formatter.format(this)
}

fun getCurrentDateTime(): Date {
    return Calendar.getInstance().time
}

Using

import ...getCurrentDateTime
import ...toString
...
...
val date = getCurrentDateTime()
val dateInString = date.toString("yyyy/MM/dd HH:mm:ss")

Reset the sequence:

SELECT setval('sequence_name', 0);

Updating current records:

UPDATE foo SET id = DEFAULT;

That's not quite true. E.g. for HTTP Windows supports URL based port sharing, allowing multiple processes to use the same IP address and Port.

HTML5 introduces the 'search' input type that I believe does what you want.

<input type="search" />

Here's a live example.

use this code to only First letter capitalization for EditText

MainActivity.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <EditText
        android:id="@+id/et"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:tag="true">
    </EditText>

</RelativeLayout>

MainActivity.java

EditText et = findViewById(R.id.et);
        et.addTextChangedListener(new TextWatcher() {
            public void beforeTextChanged(CharSequence charSequence, int i, int i1, int i2) {
            }

            public void onTextChanged(CharSequence charSequence, int i, int i1, int i2)
            {
                if (et.getText().toString().length() == 1 && et.getTag().toString().equals("true"))
                {
                    et.setTag("false");
                    et.setText(et.getText().toString().toUpperCase());
                    et.setSelection(et.getText().toString().length());
                }
                if(et.getText().toString().length() == 0)
                {
                    et.setTag("true");
                }
            }

            public void afterTextChanged(Editable editable) {

            }
        });

Instead:

public class PhotosFragment extends Fragment

You can use:

public class PhotosFragment extends ListFragment

It change the methods

    @Override
    public void onActivityCreated(Bundle savedInstanceState) {
        super.onActivityCreated(savedInstanceState);
        ArrayList<ListviewContactItem> listContact = GetlistContact();
        setAdapter(new ListviewContactAdapter(getActivity(), listContact));
    }

onActivityCreated is void and you didn't need to return a view like in onCreateView

You can see an example here

An alternative, enhanced query based on answer by dietbuddha & IanMc. The query includes description to helpfully show where rows exist and are missing. (NB: for SQL Server)

(
    select 'InTableA_NoMatchInTableB' as Msg, * from tableA
    except
    select 'InTableA_NoMatchInTableB' , * from tableB
)
union all
(
    select 'InTableB_NoMatchInTableA' as Msg, * from tableB
    except
    select 'InTableB_NNoMatchInTableA' ,* from tableA
)

To get the fragment instance in a class that extends FragmentActivity:

MyclassFragment instanceFragment=
    (MyclassFragment)getSupportFragmentManager().findFragmentById(R.id.idFragment);

To get the fragment instance in a class that extends Fragment:

MyclassFragment instanceFragment =  
    (MyclassFragment)getFragmentManager().findFragmentById(R.id.idFragment);

</shape>

There's no need to declare new variables in Python. If we're talking about variables in functions or modules, no declaration is needed. Just assign a value to a name where you need it: mymagic = "Magic". Variables in Python can hold values of any type, and you can't restrict that.

Your question specifically asks about classes, objects and instance variables though. The idiomatic way to create instance variables is in the __init__ method and nowhere else — while you could create new instance variables in other methods, or even in unrelated code, it's just a bad idea. It'll make your code hard to reason about or to maintain.

So for example:

class Thing(object):

    def __init__(self, magic):
        self.magic = magic

Easy. Now instances of this class have a magic attribute:

thingo = Thing("More magic")
# thingo.magic is now "More magic"

Creating variables in the namespace of the class itself leads to different behaviour altogether. It is functionally different, and you should only do it if you have a specific reason to. For example:

class Thing(object):

    magic = "Magic"

    def __init__(self):
        pass

Now try:

thingo = Thing()
Thing.magic = 1
# thingo.magic is now 1

Or:

class Thing(object):

    magic = ["More", "magic"]

    def __init__(self):
        pass

thing1 = Thing()
thing2 = Thing()
thing1.magic.append("here")
# thing1.magic AND thing2.magic is now ["More", "magic", "here"]

This is because the namespace of the class itself is different to the namespace of the objects created from it. I'll leave it to you to research that a bit more.

The take-home message is that idiomatic Python is to (a) initialise object attributes in your __init__ method, and (b) document the behaviour of your class as needed. You don't need to go to the trouble of full-blown Sphinx-level documentation for everything you ever write, but at least some comments about whatever details you or someone else might need to pick it up.

Add the following to the top of your file # coding=utf-8

If you go to the link in the error you can seen the reason why:

Defining the Encoding

Python will default to ASCII as standard encoding if no other encoding hints are given. To define a source code encoding, a magic comment must be placed into the source files either as first or second line in the file, such as: # coding=

Or you can encapsulate the looping logic itself in a try catch e.g.

for(int i = function2(); i < 100 /*where 100 is the end or another function call to get the end*/; i = function2()){

    try{
     //ToDo
    }
    catch { continue; }    

}

Or...

try{ 
    for(int i = function2(); ; ;) {
        try { i = function2(); return; } 
        finally { /*decide to break or not :P*/continue; } }
} catch { /*failed on first try*/ } finally{ /*afterwardz*/ }

You can use Conditional formatting with the option "Formula Is". One possible formula is

=NOT(ISBLANK($B1))

Another possible formula is

=$B1<>""

Modified from senderle's method (above). I found that Python's defaultdict is ideal for creating a trie or a prefix tree.

from collections import defaultdict

class Trie:
    """
    Implement a trie with insert, search, and startsWith methods.
    """
    def __init__(self):
        self.root = defaultdict()

    # @param {string} word
    # @return {void}
    # Inserts a word into the trie.
    def insert(self, word):
        current = self.root
        for letter in word:
            current = current.setdefault(letter, {})
        current.setdefault("_end")

    # @param {string} word
    # @return {boolean}
    # Returns if the word is in the trie.
    def search(self, word):
        current = self.root
        for letter in word:
            if letter not in current:
                return False
            current = current[letter]
        if "_end" in current:
            return True
        return False

    # @param {string} prefix
    # @return {boolean}
    # Returns if there is any word in the trie
    # that starts with the given prefix.
    def startsWith(self, prefix):
        current = self.root
        for letter in prefix:
            if letter not in current:
                return False
            current = current[letter]
        return True

# Now test the class

test = Trie()
test.insert('helloworld')
test.insert('ilikeapple')
test.insert('helloz')

print test.search('hello')
print test.startsWith('hello')
print test.search('ilikeapple')

You can use Request object or Uri object to get host of url.

Using Request.Url

string host = Request.Url.Host;

Using Uri

Uri myUri = new Uri("http://www.contoso.com:8080/");   
string host = myUri.Host;  // host is "www.contoso.com"

A slight modification of the suggestion of @Krizz, so that it works properly if the constants header file is to be included in the PCH, which is rather normal. Since the original is imported into the PCH, it won't reload it into the .m file and thus you get no symbols and the linker is unhappy.

However, the following modification allows it to work. It's a bit convoluted, but it works.

You'll need 3 files, .h file which has the constant definitions, the .h file and the .m file, I'll use ConstantList.h, Constants.h and Constants.m, respectively. the contents of Constants.h are simply:

// Constants.h
#define STR_CONST(name, value) extern NSString* const name
#include "ConstantList.h"

and the Constants.m file looks like:

// Constants.m
#ifdef STR_CONST
    #undef STR_CONST
#endif
#define STR_CONST(name, value) NSString* const name = @ value
#include "ConstantList.h"

Finally, the ConstantList.h file has the actual declarations in it and that is all:

// ConstantList.h
STR_CONST(kMyConstant, "Value");
…

A couple of things to note:

1. I had to redefine the macro in the .m file after #undefing it for the macro to be used.

2. I also had to use #include instead of #import for this to work properly and avoid the compiler seeing the previously precompiled values.

3. This will require a recompile of your PCH (and probably the entire project) whenever any values are changed, which is not the case if they are separated (and duplicated) as normal.

Hope that is helpful for someone.

here is an example, where the length of the array is changed during execution of the loop

import java.util.ArrayList;
public class VariableArrayLengthLoop {

public static void main(String[] args) {

    //create new ArrayList
    ArrayList<String> aListFruits = new ArrayList<String>();

    //add objects to ArrayList
    aListFruits.add("Apple");
    aListFruits.add("Banana");
    aListFruits.add("Orange");
    aListFruits.add("Strawberry");

    //iterate ArrayList using for loop
    for(int i = 0; i < aListFruits.size(); i++){

        System.out.println( aListFruits.get(i) + " i = "+i );
         if ( i == 2 ) {
                aListFruits.add("Pineapple");  
                System.out.println( "added now a Fruit to the List "); 
                }
        }
    }
}

Are you mixing C and C++? One issue that can occur is that the declarations in the .h file for a .c file need to be surrounded by:

#if defined(__cplusplus)
  extern "C" {                 // Make sure we have C-declarations in C++ programs
#endif

and:

#if defined(__cplusplus)
  }
#endif

Note: if unable / unwilling to modify the .h file(s) in question, you can surround their inclusion with extern "C":

extern "C" {
#include <abc.h>
} //extern

using the standard <string> header

std::string Something = "Some Text";

I had this problem when installing Heroku Toolbelt

This is how I solved the problem

$ ls -l /bin/sh
lrwxrwxrwx 1 root root 4 ago 15  2012 /bin/sh -> dash

As you can see, /bin/sh is a link to "dash" (not bash), and [[ is bash syntactic sugarness. So I just replaced the link to /bin/bash. Careful using rm like this in your system!

$ sudo rm /bin/sh
$ sudo ln -s /bin/bash /bin/sh

Just give them the same name throughout the form you are using.

<form><input type="radio" name="selection">
      <input type="radio" name="selection">

Having fixed the height and width you sholud tell the how to bahave if the text inside it overflows its area. So add in the css

overflow: auto;

You can use the following code to both work with the command line and a web browser. Put this code above your PHP code. It creates a $_GET variable for each command line parameter.

In your code you only need to check for $_GET variables then, not worrying about if the script is called from the web browser or command line.

if(isset($argv))
    foreach ($argv as $arg) {
        $e=explode("=",$arg);
        if(count($e)==2)
            $_GET[$e[0]]=$e[1];
        else
            $_GET[$e[0]]=0;
    }

For portability to pre-Bash 3.1 (when the =~ test was introduced), use expr.

if expr "$string" : '-\?[0-9]\+$' >/dev/null
then
  echo "String is a valid integer."
else
  echo "String is not a valid integer."
fi

expr STRING : REGEX searches for REGEX anchored at the start of STRING, echoing the first group (or length of match, if none) and returning success/failure. This is old regex syntax, hence the excess \. -\? means "maybe -", [0-9]\+ means "one or more digits", and $ means "end of string".

Bash also supports extended globs, though I don't recall from which version onwards.

shopt -s extglob
case "$string" of
    @(-|)[0-9]*([0-9]))
        echo "String is a valid integer." ;;
    *)
        echo "String is not a valid integer." ;;
esac

# equivalently, [[ $string = @(-|)[0-9]*([0-9])) ]]

@(-|) means "- or nothing", [0-9] means "digit", and *([0-9]) means "zero or more digits".

I tried a few things, favouring pattern matching as a way of avoiding casting but ran into trouble with type erasure on the collection types.

The main problem seems to be that the complete type of the parse result mirrors the structure of the JSON data and is either cumbersome or impossible to fully state. I guess that is why Any is used to truncate the type definitions. Using Any leads to the need for casting.

I've hacked something below which is concise but is extremely specific to the JSON data implied by the code in the question. Something more general would be more satisfactory but I'm not sure if it would be very elegant.

implicit def any2string(a: Any)  = a.toString
implicit def any2boolean(a: Any) = a.asInstanceOf[Boolean]
implicit def any2double(a: Any)  = a.asInstanceOf[Double]

case class Language(name: String, isActive: Boolean, completeness: Double)

val languages = JSON.parseFull(jstr) match {
  case Some(x) => {
    val m = x.asInstanceOf[Map[String, List[Map[String, Any]]]]

    m("languages") map {l => Language(l("name"), l("isActive"), l("completeness"))}
  }
  case None => Nil
}

languages foreach {println}

Updates to reports

In late May 2018, you may begin to see changes in your app's metrics based on your users' deletion of data. Some metrics are calculated based on data from users who have agreed to share their data with developers in aggregate.

The metrics that we provide in the Play Console are adjusted to more closely reflect data from all of your users. However, Google will not display data that falls under certain minimum thresholds.

Delete an app or game

You can permanently remove draft apps or games from your Play Console. You can also delete:

1. Published apps or games that haven't been installed on any devices
2. Published apps or games that no users are entitled to re-install

In these cases, contact our support team to request that your app's or game's data be permanently deleted.

@FunctionalInterface annotation is useful for compilation time checking of your code. You cannot have more than one method besides static, default and abstract methods that override methods in Object in your @FunctionalInterface or any other interface used as a functional interface.

But you can use lambdas without this annotation as well as you can override methods without @Override annotation.

From docs

a functional interface has exactly one abstract method. Since default methods have an implementation, they are not abstract. If an interface declares an abstract method overriding one of the public methods of java.lang.Object, that also does not count toward the interface's abstract method count since any implementation of the interface will have an implementation from java.lang.Object or elsewhere

This can be used in lambda expression:

public interface Foo {
  public void doSomething();
}

This cannot be used in lambda expression:

public interface Foo {
  public void doSomething();
  public void doSomethingElse();
}

But this will give compilation error:

@FunctionalInterface
public interface Foo {
  public void doSomething();
  public void doSomethingElse();
}

Invalid '@FunctionalInterface' annotation; Foo is not a functional interface

It is not true that quicksort is better. ALso, it depends on what you mean better, memory consumption, or speed.

In terms of memory consumption, in worst case, but quicksort can use n^2 memory (i.e. each partition is 1 to n-1), whereas merge sort uses nlogn.

The above follows in terms of speed.

Be careful where you set WORKDIR because it can affect the continuous integration flow. For example, setting it to /home/circleci/project will cause error something like .ssh or whatever is the remote circleci is doing at setup time.
