Use permission symbols instead of numbers

Your problem would have been avoided if you had used the more semantically named permission symbols rather than raw magic numbers, e.g. for 664:

#!/usr/bin/env python3

import os
import stat

os.chmod(
    'myfile',
    stat.S_IRUSR |
    stat.S_IWUSR |
    stat.S_IRGRP |
    stat.S_IWGRP |
    stat.S_IROTH
)

This is documented at https://docs.python.org/3/library/os.html#os.chmod and the names are the same as the POSIX C API values documented at man 2 stat.

Another advantage is the greater portability as mentioned in the docs:

Note: Although Windows supports chmod(), you can only set the file’s read-only flag with it (via the stat.S_IWRITE and stat.S_IREAD constants or a corresponding integer value). All other bits are ignored.

chmod +x is demonstrated at: How do you do a simple "chmod +x" from within python?

Tested in Ubuntu 16.04, Python 3.5.2.

Try this:

1. Go to: C:/Users/(YourUserName)/
2. Delete file .gitconfig

I'm fairly certain the answer is: No. You can select options with JavaScript but not open the select. You'd have to use a custom solution.

To remove bullet points from unordered lists , you can use:

list-style: none;

You can also use:

list-style-type: none;

Either works but the first is a shorter way to get the same result.

Just append a div with that class to body, then remove it when you're done:

// Show the backdrop
$('<div class="modal-backdrop"></div>').appendTo(document.body);

// Remove it (later)
$(".modal-backdrop").remove();

Live Example:

$("input").click(function() {_x000D_
  var bd = $('<div class="modal-backdrop"></div>');_x000D_
  bd.appendTo(document.body);_x000D_
  setTimeout(function() {_x000D_
    bd.remove();_x000D_
  }, 2000);_x000D_
});

HOW TO ANIMATE OPACITY WITH CSS:
this is my code:
the CSS code

.item {   
    height:200px;
    width:200px;
    background:red;
    opacity:0;
    transition: opacity 1s ease-in-out;
}

.item:hover {
    opacity: 1;
}
code {
    background: linear-gradient(to right,#fce4ed,#ffe8cc);
}

<div class="item">

</div>
<p><code> move mouse over top of this text</code></p>

or check this demo file

function vote(){
var vote = getElementById("yourOpinion")
if(this.workWithYou):
vote += 1 };
lol

rlang::has_name() can do this too:

foo = list(a = 1, bb = NULL)
rlang::has_name(foo, "a")  # TRUE
rlang::has_name(foo, "b")  # FALSE. No partial matching
rlang::has_name(foo, "bb")  # TRUE. Handles NULL correctly
rlang::has_name(foo, "c")  # FALSE

As you can see, it inherently handles all the cases that @Tommy showed how to handle using base R and works for lists with unnamed items. I would still recommend exists("bb", where = foo) as proposed in another answer for readability, but has_name is an alternative if you have unnamed items.

Using Angular 4 and the cli that came with it I was able to start the server with $npm start -- --port 8000. That worked ok: ** NG Live Development Server is listening on localhost:8000, open your browser on http://localhost:8000 **

Got the tip from Here

As Jason says, you can create a variable of the right type and pass that. You might want to encapsulate it in your own method:

public static DateTime? TryParse(string text)
{
    DateTime date;
    if (DateTime.TryParse(text, out date))
    {
        return date;
    }
    else
    {
        return null;
    }
}

... or if you like the conditional operator:

public static DateTime? TryParse(string text)
{
    DateTime date;
    return DateTime.TryParse(text, out date) ? date : (DateTime?) null;
}

Or in C# 7:

public static DateTime? TryParse(string text) =>
    DateTime.TryParse(text, out var date) ? date : (DateTime?) null;

Boomerang may also be worth checking out.

If you only need to work on Unix, you can use a system call (ref. Stack Overflow question Parse ifconfig to get only my IP address using Bash):

import os
f = os.popen('ifconfig eth0 | grep "inet\ addr" | cut -d: -f2 | cut -d" " -f1')
your_ip=f.read()

Installing the packages globally is one way to do it, but this restricts you to using the same version across all projects in which they are used.

Instead, you can prefix your npm scripts with ./node_modules/.bin. In your case, the package.json would look like this:

{
  "name": "reservationsystem",
  "version": "0.0.1",
  "scripts": {
    "tsc": "./node_modules/.bin/tsc",
    "tsc:w": "npm run tsc -w",
    "lite": "./node_modules/.bin/lite-server",
    "start": "./node_modules/.bin/concurrent \"npm run tsc:w\" \"npm run lite\" "
  },
  "dependencies": {
    "a2-in-memory-web-api": "~0.1.0",
    "angular2": "2.0.0-beta.3",
    "es6-promise": "^3.0.2",
    "es6-shim": "^0.33.3",
    "reflect-metadata": "0.1.2",
    "rxjs": "5.0.0-beta.0",
    "systemjs": "0.19.17",
    "zone.js": "0.5.11"
  },
  "devDependencies": {
    "concurrently": "^1.0.0",
    "lite-server": "^2.0.1",
    "typescript": "^1.7.5"
  }
}

I think npm is supposed to supply the ./node_modules/.bin in front of each "script" command that's in that directory by default, which is why the original package.json looked the way it did. I am not sure if that feature is in every release of npm, or if there's some config setting you're supposed to specify. It'd be worth looking into!

put string first

Intent secondIntent = new Intent(this, typeof(SecondActivity));
            secondIntent.PutExtra("message", "Greetings from MainActivity");

retrieve it after that

var message = this.Intent.GetStringExtra("message");

thats All ;)

In a relational database all types of relationships are represented in the same way: as relations. The candidate key(s) of each relation (and possibly other constraints as well) determine what kind of relationship is being represented. 1:n and m:n are two kinds of binary relationship:

C {Employee*,Company}
B {Book*,Author*}

In each case * designates the key attribute(s). {Book,Author} is a compound key.

C is a relation where each employee works for only one company but each company may have many employees (1:n): B is a relation where a book can have many authors and an author may write many books (m:n):

Notice that the key constraints ensure that each employee can only be associated with one company whereas any combination of books and authors is permitted.

Other kinds of relationship are possible as well: n-ary (having more than two components); fixed cardinality (m:n where m and n are fixed constants or ranges); directional; and so on. William Kent in his book "Data and Reality" identifies at least 432 kinds - and that's just for binary relationships. In practice, the binary relationships 1:n and m:n are very common and are usually singled out as specially important in designing and understanding data models.

I like @CHR15TO's answer, unlike other answers I've seen on other similar questions, that answer actually shows how to properly escape a user provided search string (rather than saying it would be necessary without showing how).

However, it's still quite clunky, and possibly relatively slower. So why not have a specific solution to what is likely a common requirement for coders? (And why not include it in the ES6 API BTW?)

My answer [https://stackoverflow.com/a/38290557/887092] on a similar question enables the following:

var haystack = 'A. BAIL. Of. Hay.';
var needle = 'bail.';
var index = haystack.naturalIndexOf(needle);

If you are stuck with .NET 2.0 and managed code, here is another way that works whith local and domain accounts:

using System;
using System.Collections.Generic;
using System.Text;
using System.Security;
using System.Diagnostics;

static public bool Validate(string domain, string username, string password)
{
    try
    {
        Process proc = new Process();
        proc.StartInfo = new ProcessStartInfo()
        {
            FileName = "no_matter.xyz",
            CreateNoWindow = true,
            WindowStyle = ProcessWindowStyle.Hidden,
            WorkingDirectory = Environment.GetFolderPath(Environment.SpecialFolder.CommonApplicationData),
            UseShellExecute = false,
            RedirectStandardError = true,
            RedirectStandardOutput = true,
            RedirectStandardInput = true,
            LoadUserProfile = true,
            Domain = String.IsNullOrEmpty(domain) ? "" : domain,
            UserName = username,
            Password = Credentials.ToSecureString(password)
        };
        proc.Start();
        proc.WaitForExit();
    }
    catch (System.ComponentModel.Win32Exception ex)
    {
        switch (ex.NativeErrorCode)
        {
            case 1326: return false;
            case 2: return true;
            default: throw ex;
        }
    }
    catch (Exception ex)
    {
        throw ex;
    }

    return false;
}   

Yes, there is a way to show a single command output on the console (screen) and in a file. Using your example, use...

@ECHO OFF
FOR /F "tokens=*" %%I IN ('DIR') DO ECHO %%I & ECHO %%I>>windows-dir.txt

Detailed explanation:

The FOR command parses the output of a command or text into a variable, which can be referenced multiple times.

For a command, such as DIR /B, enclose in single quotes as shown in example below. Replace the DIR /B text with your desired command.

FOR /F "tokens=*" %%I IN ('DIR /B') DO ECHO %%I & ECHO %%I>>FILE.TXT

For displaying text, enclose text in double quotes as shown in example below.

FOR /F "tokens=*" %%I IN ("Find this text on console (screen) and in file") DO ECHO %%I & ECHO %%I>>FILE.TXT

... And with line wrapping...

FOR /F "tokens=*" %%I IN ("Find this text on console (screen) and in file") DO (
  ECHO %%I & ECHO %%I>>FILE.TXT
)

If you have times when you want the output only on console (screen), and other times sent only to file, and other times sent to both, specify the "DO" clause of the FOR loop using a variable, as shown below with %TOECHOWHERE%.

@ECHO OFF
FOR %%I IN (TRUE FALSE) DO (
  FOR %%J IN (TRUE FALSE) DO (
    SET TOSCREEN=%%I & SET TOFILE=%%J & CALL :Runit)
)
GOTO :Finish

:Runit
  REM Both TOSCREEN and TOFILE get assigned a trailing space in the FOR loops
  REM above when the FOR loops are evaluating the first item in the list,
  REM "TRUE".  So, the first value of TOSCREEN is "TRUE " (with a trailing
  REM space), the second value is "FALSE" (no trailing or leading space).
  REM Adding the ": =" text after "TOSCREEN" tells the command processor to
  REM remove all spaces from the value in the "TOSCREEN" variable.
  IF "%TOSCREEN: =%"=="TRUE" (
      IF "%TOFILE: =%"=="TRUE" (
          SET TEXT=On screen, and in "FILE.TXT"
          SET TOECHOWHERE="ECHO %%I & ECHO %%I>>FILE.TXT"
        ) ELSE (
          SET TEXT=On screen, not in "FILE.TXT"
          SET TOECHOWHERE="ECHO %%I"
      )
    ) ELSE (
      IF "%TOFILE: =%"=="TRUE" (
          SET TEXT=Not on screen, but in "FILE.TXT"
          SET TOECHOWHERE="ECHO %%I>>FILE.txt"
        ) ELSE (
          SET TEXT=Not on screen, nor in "FILE.TXT"
          SET TOECHOWHERE="ECHO %%I>NUL"
      )
  )
  FOR /F "tokens=*" %%I IN ("%TEXT%") DO %TOECHOWHERE:~1,-1%
GOTO :eof

:Finish
  ECHO Finished [this text to console (screen) only].

In xaml

<TextBlock Text="{Binding CelsiusTemp}" />

In ViewModel, this way setting the value also works:

 public string CelsiusTemp
        {
            get { return string.Format("{0}°C", _CelsiusTemp); }
            set
            {
                value = value.Replace("°C", "");
              _CelsiusTemp = value;
            }
        }

This examples shows calling a method

1. Defined in Child widget from Parent widget.
2. Defined in Parent widget from Child widget.

class ParentPage extends StatefulWidget {
  @override
  _ParentPageState createState() => _ParentPageState();
}

class _ParentPageState extends State<ParentPage> {
  final GlobalKey<ChildPageState> _key = GlobalKey();

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(title: Text("Parent")),
      body: Center(
        child: Column(
          children: <Widget>[
            Expanded(
              child: Container(
                color: Colors.grey,
                width: double.infinity,
                alignment: Alignment.center,
                child: RaisedButton(
                  child: Text("Call method in child"),
                  onPressed: () => _key.currentState.methodInChild(), // calls method in child
                ),
              ),
            ),
            Text("Above = Parent\nBelow = Child"),
            Expanded(
              child: ChildPage(
                key: _key,
                function: methodInParent,
              ),
            ),
          ],
        ),
      ),
    );
  }

  methodInParent() => Fluttertoast.showToast(msg: "Method called in parent", gravity: ToastGravity.CENTER);
}

class ChildPage extends StatefulWidget {
  final Function function;

  ChildPage({Key key, this.function}) : super(key: key);

  @override
  ChildPageState createState() => ChildPageState();
}

class ChildPageState extends State<ChildPage> {
  @override
  Widget build(BuildContext context) {
    return Container(
      color: Colors.teal,
      width: double.infinity,
      alignment: Alignment.center,
      child: RaisedButton(
        child: Text("Call method in parent"),
        onPressed: () => widget.function(), // calls method in parent
      ),
    );
  }

  methodInChild() => Fluttertoast.showToast(msg: "Method called in child");
}

I also needed the current screen dimension, specifically the Work-area, which returned the rectangle excluding the Taskbar width.

I used it in order to reposition a window, which is opened to the right and down to where the mouse is positioned. Since the window is fairly large, in many cases it got out of the screen bounds. The following code is based on @e-j answer: This will give you the current screen.... The difference is that I also show my repositioning algorithm, which I assume is actually the point.

The code:

using System.Windows;
using System.Windows.Forms;

namespace MySample
{

    public class WindowPostion
    {
        /// <summary>
        /// This method adjust the window position to avoid from it going 
        /// out of screen bounds.
        /// </summary>
        /// <param name="topLeft">The requiered possition without its offset</param>
        /// <param name="maxSize">The max possible size of the window</param>
        /// <param name="offset">The offset of the topLeft postion</param>
        /// <param name="margin">The margin from the screen</param>
        /// <returns>The adjusted position of the window</returns>
        System.Drawing.Point Adjust(System.Drawing.Point topLeft, System.Drawing.Point maxSize, int offset, int margin)
        {
            Screen currentScreen = Screen.FromPoint(topLeft);
            System.Drawing.Rectangle rect = currentScreen.WorkingArea;

            // Set an offset from mouse position.
            topLeft.Offset(offset, offset);

            // Check if the window needs to go above the task bar, 
            // when the task bar shadows the HUD window.
            int totalHight = topLeft.Y + maxSize.Y + margin;

            if (totalHight > rect.Bottom)
            {
                topLeft.Y -= (totalHight - rect.Bottom);

                // If the screen dimensions exceed the hight of the window
                // set it just bellow the top bound.
                if (topLeft.Y < rect.Top)
                {
                    topLeft.Y = rect.Top + margin;
                }
            }

            int totalWidth = topLeft.X + maxSize.X + margin;
            // Check if the window needs to move to the left of the mouse, 
            // when the HUD exceeds the right window bounds.
            if (totalWidth > rect.Right)
            {
                // Since we already set an offset remove it and add the offset 
                // to the other side of the mouse (2x) in addition include the 
                // margin.
                topLeft.X -= (maxSize.X + (2 * offset + margin));

                // If the screen dimensions exceed the width of the window
                // don't exceed the left bound.
                if (topLeft.X < rect.Left)
                {
                    topLeft.X = rect.Left + margin;
                }
            }

            return topLeft;
        }
    }
}

Some explanations:

1) topLeft - position of the top left at the desktop (works                     
   for multi screens - with different aspect ratio).                            
            Screen1              Screen2

   If the mouse is in Screen3 a possible value might be:                        
   topLeft.X=4140 topLeft.Y=195                                                 
2) offset - the offset from the top left, one value for both                    
   X and Y directions.                                                          
3) maxSize - the maximal size of the window - including its                     
   size when it is expanded - from the following example                        
   we need maxSize.X = 200, maxSize.Y = 150 - To avoid the expansion            
   being out of bound.

• I had no choice but using the code format (otherwise the white spaces would have been lost).
• Originally this appeared in the code above as a <remark><code>...</code></remark>

What I've done is more clean and needs to make two arrays :

• one contains a list of Object with id and a text (in my case its id and name, depending of your templateResult) (its what you get from ajax query)
• the second is only an array of ids (selection value)

I initialize select2 using the first array as data, and the second as the val.

An example function with as parameters a dict of id:name.

function initMyList(values) {
    var selected = [];
    var initials = [];

    for (var s in values) {
        initials.push({id: s, name: values[s].name});
        selected.push(s);
    }

    $('#myselect2').select2({
        data: initials,
        ajax: {
            url: "/path/to/value/",
            dataType: 'json',
            delay: 250,
            data: function (params) {
                return {
                    term: params.term,
                    page: params.page || 1,
                };
            },
            processResults: function (data, params) {
                params.page = params.page || 1;

                return {
                    results: data.items,
                    pagination: {
                        more: (params.page * 30) < data.total_count
                    }
                };
            },
            cache: true
        },
        minimumInputLength: 1,
        tokenSeparators: [",", " "],
        placeholder: "Select none, one or many values",
        templateResult: function (item) { return item.name; },
        templateSelection: function (item) { return item.name; },
        matcher: function(term, text) { return text.name.toUpperCase().indexOf(term.toUpperCase()) != -1; },
    });

    $('#myselect2').val(selected).trigger('change');
}

You can feed the initials value using ajax calls, and use jquery promises to do the select2 initialization.

Toggle function in react

At first you should create constructor like this

constructor(props) {
        super(props);
        this.state = {
            close: true,
        };
    }

Then create a function like this

yourFunction = () => {
        this.setState({
            close: !this.state.close,
        });
    };

then use this like

render() {
        const {close} = this.state;
        return (

            <Fragment>

                 <div onClick={() => this.yourFunction()}></div>

                 <div className={close ? "isYourDefaultClass" : "isYourOnChangeClass"}></div>

            </Fragment>
        )
    }
}

Please give better solutions

Perhaps the whole column full of random numbers is not the best way to do it, but it seems like probably the most practical as @mariusnn mentioned.

On that note, this stomped me for a while with Office 2010, and while generally answers like the one in lifehacker work,I just wanted to share an extra step required for the numbers to be unique:

1. Create a new column next to the list that you're going to randomize
2. Type in =rand() in the first cell of the new column - this will generate a random number between 0 and 1

3. Fill the column with that formula. The easiest way to do this may be to:

   • go down along the new column up until the last cell that you want to randomize
   • hold down Shift and click on the last cell
   • press Ctrl+D

4. Now you should have a column of identical numbers, even though they are all generated randomly.

   

   The trick here is to recalculate them! Go to the Formulas tab and then click on Calculate Now (or press F9).

   

   Now all the numbers in the column will be actually generated randomly.

5. Go to the Home tab and click on Sort & Filter. Choose whichever order you want (Smallest to Largest or Largest to Smallest) - whichever one will give you a random order with respect to the original order. Then click OK when the Sort Warning prompts you to Expand the selection.

6. Your list should be randomized now! You can get rid of the column of random numbers if you want.

it's simple, set canvas width and height to screen.width and screen.height. then press F11! think F11 should make full screen in most browsers does in FFox and IE.

I don't think you're setting the header correctly, try this:

header('HTTP/1.0 401 Unauthorized');

Depending on your version:

Python 2.x:

for key, val in PIX0.iteritems():
    NUM = input("Which standard has a resolution of {!r}?".format(val))
    if NUM == key:
        print ("Nice Job!")
        count = count + 1
    else:
        print("I'm sorry but thats wrong. The correct answer was: {!r}.".format(key))

Python 3.x:

for key, val in PIX0.items():
    NUM = input("Which standard has a resolution of {!r}?".format(val))
    if NUM == key:
        print ("Nice Job!")
        count = count + 1
    else:
        print("I'm sorry but thats wrong. The correct answer was: {!r}.".format(key))

You should also get in the habit of using the new string formatting syntax ({} instead of % operator) from PEP 3101:

https://www.python.org/dev/peps/pep-3101/

I thought that PCLint would do this, but it has been a few years since I've looked at it. You might check it out.

I looked at this blog and the author talked a bit about configuring PCLint to find unused includes. Might be worth a look.

You also can do it using Data Export tool in dbForge Studio for MySQL.

It will allow you to select some or all tables and export them into CSV format.

In the following example you have an PHP array, then firstly create a JavaScript array by a PHP array:

<script type="javascript">
    day = new Array(<?php echo implode(',', $day); ?>);
    week = new Array(<?php echo implode(',',$week); ?>);
    month = new Array(<?php echo implode(',',$month); ?>);

    <!--  Then pass it to the JavaScript function:   -->

    drawChart(<?php echo count($day); ?>, day, week, month);
</script>

You could use label based using .loc or index based using .iloc method to do column-slicing including column ranges:

In [50]: import pandas as pd

In [51]: import numpy as np

In [52]: df = pd.DataFrame(np.random.rand(4,4), columns = list('abcd'))

In [53]: df
Out[53]: 
          a         b         c         d

It means: "A class that you use needs another class that is not on the classpath." You should make sure (as Harry Joy suggests) to add the required jar to the classpath.

You can use the following line of code in the activity's onCreate method to make sure the keyboard only pops up when a user clicks into an EditText

this.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN); 

To see just the Python releases, do conda search --full-name python.

I too get this error sometimes when I dismiss dialog and finish activity from onPostExecute method. I guess sometimes activity gets finished before dialog successfully dismisses.

Simple, yet effective solution that works for me

@Override
protected void onPostExecute(MyResult result) {
    try {
        if ((this.mDialog != null) && this.mDialog.isShowing()) {
            this.mDialog.dismiss();
        }
    } catch (final IllegalArgumentException e) {
        // Handle or log or ignore
    } catch (final Exception e) {
        // Handle or log or ignore
    } finally {
        this.mDialog = null;
    }  
}

Well, what do you try to do? If you want to use division, use "/" not "\". If it is something else, explain it in a bit more detail, please.

Had the same problem today after i've upgraded my npm from version 6.4.1 to version 6.5.0. I fixed this by downloading the .pkg installer (recommended for most users) from node.js and runned it afterwards.

If statement is used for checking just one condition quickly. When you have multiple options, use <xsl:choose> as illustrated below:

   <xsl:choose>
     <xsl:when test="$CreatedDate > $IDAppendedDate">
       <h2>mooooooooooooo</h2>
     </xsl:when>
     <xsl:otherwise>
      <h2>dooooooooooooo</h2>
     </xsl:otherwise>
   </xsl:choose>

Also, you can use multiple <xsl:when> tags to express If .. Else If or Switch patterns as illustrated below:

   <xsl:choose>
     <xsl:when test="$CreatedDate > $IDAppendedDate">
       <h2>mooooooooooooo</h2>
     </xsl:when>
     <xsl:when test="$CreatedDate = $IDAppendedDate">
       <h2>booooooooooooo</h2>
     </xsl:when>
     <xsl:otherwise>
      <h2>dooooooooooooo</h2>
     </xsl:otherwise>
   </xsl:choose>

The previous example would be equivalent to the pseudocode below:

   if ($CreatedDate > $IDAppendedDate)
   {
       output: <h2>mooooooooooooo</h2>
   }
   else if ($CreatedDate = $IDAppendedDate)
   {
       output: <h2>booooooooooooo</h2>
   }
   else
   {
       output: <h2>dooooooooooooo</h2>
   }

For Excel 2010 it should be UTF-8. Instruction by MS :
http://msdn.microsoft.com/en-us/library/bb507946:

"The basic document structure of a SpreadsheetML document consists of the Sheets and Sheet elements, which reference the worksheets in the Workbook. A separate XML file is created for each Worksheet. For example, the SpreadsheetML for a workbook that has two worksheets name MySheet1 and MySheet2 is located in the Workbook.xml file and is shown in the following code example.

<?xml version="1.0" encoding="UTF-8" standalone="yes" ?> 
<workbook xmlns=http://schemas.openxmlformats.org/spreadsheetml/2006/main xmlns:r="http://schemas.openxmlformats.org/officeDocument/2006/relationships">
    <sheets>
        <sheet name="MySheet1" sheetId="1" r:id="rId1" /> 
        <sheet name="MySheet2" sheetId="2" r:id="rId2" /> 
    </sheets>
</workbook>

The worksheet XML files contain one or more block level elements such as SheetData. sheetData represents the cell table and contains one or more Row elements. A row contains one or more Cell elements. Each cell contains a CellValue element that represents the value of the cell. For example, the SpreadsheetML for the first worksheet in a workbook, that only has the value 100 in cell A1, is located in the Sheet1.xml file and is shown in the following code example.

<?xml version="1.0" encoding="UTF-8" ?> 
<worksheet xmlns="http://schemas.openxmlformats.org/spreadsheetml/2006/main">
    <sheetData>
        <row r="1">
            <c r="A1">
                <v>100</v> 
            </c>
        </row>
    </sheetData>
</worksheet>

One could simply use this

You can have both TortoiseSVN and the Apache Subversion command line tools installed. I usually install the Apache SVN tools from the VisualSVN download site: https://www.visualsvn.com/downloads/

Once installed, place the Subversion\bin in your set PATH. Then you will be able to use TortoiseSVN when you want to use the GUI, and you have the proper SVN command line tools to use from the command line.

If you don't want to install Homebrew only for install Maven you could simply do this:

1. Download the binary Maven and extract the zip

2. Launch the Terminal and type this command:

   sudo ln -s /path_to_maven_folder/bin/mvn /usr/bin/mvn

If you want to load the partial view directly inside the main view you could use the Html.Action helper:

@Html.Action("Load", "Home")

or if you don't want to go through the Load action use the HtmlPartialAsync helper:

@await Html.PartialAsync("_LoadView")

If you want to use Ajax.ActionLink, replace your Html.ActionLink with:

@Ajax.ActionLink(
    "load partial view", 
    "Load", 
    "Home", 
    new AjaxOptions { UpdateTargetId = "result" }
)

and of course you need to include a holder in your page where the partial will be displayed:

<div id="result"></div>

Also don't forget to include:

<script src="@Url.Content("~/Scripts/jquery.unobtrusive-ajax.js")" type="text/javascript"></script>

in your main view in order to enable Ajax.* helpers. And make sure that unobtrusive javascript is enabled in your web.config (it should be by default):

<add key="UnobtrusiveJavaScriptEnabled" value="true" />

All the code provided in the other answers is correct and is working fine, but a bit messy, so I decided to publish a library (still in development though) to use it in a easier way: AndroidMail.

You have just to create a MailSender, build a mail and send it (already handled in background with an AsyncTask).

MailSender mailSender = new MailSender(email, password);

Mail.MailBuilder builder = new Mail.MailBuilder();
Mail mail = builder
    .setSender(senderMail)
    .addRecipient(new Recipient(recipient))
    .setText("Hello")
    .build();

mailSender.sendMail(mail);

You can receive a notification for the email sent and it has also the support for different Recipients types (TO, CC and BCC), attachments and html:

MailSender mailSender = new MailSender(email, password);

Mail.MailBuilder builder = new Mail.MailBuilder();
Mail mail = builder
    .setSender(senderMail)
    .addRecipient(new Recipient(recipient))
    .addRecipient(new Recipient(Recipient.TYPE.CC, recipientCC))
    .setText("Hello")
    .setHtml("<h1 style=\"color:red;\">Hello</h1>")
    .addAttachment(new Attachment(filePath, fileName))
    .build();

mailSender.sendMail(mail, new MailSender.OnMailSentListener() {

    @Override
    public void onSuccess() {
        // mail sent!
    }

    @Override
    public void onError(Exception error) {
        // something bad happened :(
    }
});

You can get it via Gradle or Maven:

compile 'it.enricocandino:androidmail:1.0.0-SNAPSHOT'

Please let me know if you have any issue with it! :)

For what it's worth, you can use the autofocus attribute on HTML5 compatible browsers. Works even on IE as of version 10.

<input name="myinput" value="whatever" autofocus />

You can pass parameters to sp_GetById and fetch the results either in ToList() or FirstOrDefault();

var param  = new SqlParameter("@id", 106);
var result = dbContext
               .Database
               .SqlQuery<Category>("dbo.sp_GetById @id", param)
               .FirstOrDefault();

Programmatically you can do it by adding the following constraints.

NSLayoutConstraint *constraintHorizontal = [NSLayoutConstraint constraintWithItem:self

                                                                       constant:0.0f];

NSLayoutConstraint *constraintVertical = [NSLayoutConstraint constraintWithItem:self
                                                                        attribute:NSLayoutAttributeCenterY 
                                                                        relatedBy:NSLayoutRelationEqual
                                                                           toItem:self.superview 
                                                                        attribute:attribute 
                                                                       multiplier:1.0f
                                                                         constant:0.0f];

my_file = open("first_file.txt", "r")
for line in my_file.readlines():
    if line[-1:] == "\n":
        print(line[:-1])
    else:
        print(line)
my_file.close() 

As I commented above, problem seems to be the conversion from PIL internal list format to a standard python list type. I've found that Image.tostring() is much faster, and depending on your needs it might be enough. In my case, I needed to calculate the CRC32 digest of image data, and it suited fine.

If you need to perform more complex calculations, tom10 response involving numpy might be what you need.

Assert.That(myTestDelegate, Throws.ArgumentException
    .With.Property("Message").EqualTo("your argument is invalid."));

dynamic_cast has runtime type checking and only works with references and pointers, whereas static_cast does not offer runtime type checking. For complete information, see the MSDN article static_cast Operator.

In case of a 2D array (matrix), you can use:

[val, idx] = max(A, [], 2);

The idx part will contain the column number of containing the max element of each row.

I know this is an older subject, however Mocking a MVC application for unit tests is something we do on very regular basis.

I just wanted to add my experiences Mocking a MVC 3 application using Moq 4 after upgrading to Visual Studio 2013. None of the unit tests were working in debug mode and the HttpContext was showing "could not evaluate expression" when trying to peek at the variables.

Turns out visual studio 2013 has issues evaluating some objects. To get debugging mocked web applications working again, I had to check the "Use Managed Compatibility Mode" in Tools=>Options=>Debugging=>General settings.

I generally do something like this:

public static class FakeHttpContext
{
    public static void SetFakeContext(this Controller controller)
    {

        var httpContext = MakeFakeContext();
        ControllerContext context =
        new ControllerContext(
        new RequestContext(httpContext,
        new RouteData()), controller);
        controller.ControllerContext = context;
    }


    private static HttpContextBase MakeFakeContext()
    {
        var context = new Mock<HttpContextBase>();
        var request = new Mock<HttpRequestBase>();
        var response = new Mock<HttpResponseBase>();
        var session = new Mock<HttpSessionStateBase>();
        var server = new Mock<HttpServerUtilityBase>();
        var user = new Mock<IPrincipal>();
        var identity = new Mock<IIdentity>();

        context.Setup(c=> c.Request).Returns(request.Object);
        context.Setup(c=> c.Response).Returns(response.Object);
        context.Setup(c=> c.Session).Returns(session.Object);
        context.Setup(c=> c.Server).Returns(server.Object);
        context.Setup(c=> c.User).Returns(user.Object);
        user.Setup(c=> c.Identity).Returns(identity.Object);
        identity.Setup(i => i.IsAuthenticated).Returns(true);
        identity.Setup(i => i.Name).Returns("admin");

        return context.Object;
    }


}

And initiating the context like this

FakeHttpContext.SetFakeContext(moController);

And calling the Method in the controller straight forward

long lReportStatusID = -1;
var result = moController.CancelReport(lReportStatusID);

This is what operator.itemgetter is for.

>>> a = [(1, u'abc'), (2, u'def')]
>>> import operator
>>> b = map(operator.itemgetter(0), a)
>>> b
[1, 2]

The itemgetter statement returns a function that returns the index of the element you specify. It's exactly the same as writing

>>> b = map(lambda x: x[0], a)

But I find that itemgetter is a clearer and more explicit.

This is handy for making compact sort statements. For example,

>>> c = sorted(a, key=operator.itemgetter(0), reverse=True)
>>> c
[(2, u'def'), (1, u'abc')]

Both GET and POST are used by the browser to request a single resource from the server. Each resource requires a separate GET or POST request.

1. The GET method is most commonly (and is the default method) used by browsers to retrieve information from servers. When using the GET method the 3rd section of the request packet, which is the request body, remains empty.

The GET method is used in one of two ways: When no method is specified, that is when you or the browser is requesting a simple resource such as an HTML page, an image, etc. When a form is submitted, and you choose method=GET on the HTML tag. If the GET method is used with an HTML form, then the data collected through the form is sent to the server by appending a "?" to the end of the URL, and then adding all name=value pairs (name of the html form field and value entered in that field) separated by an "&" Example: GET /sultans/shop//form1.jsp?name=Sam%20Sultan&iceCream=vanilla HTTP/1.0 optional headeroptional header<< empty line >>>

The name=value form data will be stored in an environment variable called QUERY_STRING. This variable will be sent to a processing program (such as JSP, Java servlet, PHP etc.)

2. The POST method is used when you create an HTML form, and request method=POST as part of the tag. The POST method allows the client to send form data to the server in the request body section of the request (as discussed earlier). The data is encoded and is formatted similar to the GET method, except that the data is sent to the program through the standard input.

Example: POST /sultans/shop//form1.jsp HTTP/1.0 optional headeroptional header<< empty line >>> name=Sam%20Sultan&iceCream=vanilla

When using the post method, the QUERY_STRING environment variable will be empty. Advantages/Disadvantages of GET vs. POST

Advantages of the GET method: Slightly faster Parameters can be entered via a form or by appending them after the URL Page can be bookmarked with its parameters

Disadvantages of the GET method: Can only send 4K worth of data. (You should not use it when using a textarea field) Parameters are visible at the end of the URL

Advantages of the POST method: Parameters are not visible at the end of the URL. (Use for sensitive data) Can send more that 4K worth of data to server

Disadvantages of the POST method: Can cannot be bookmarked with its data

and another way:

$input = array(
    'item1'  => 'object1',
    'item2'  => 'object2',
    'item-n' => 'object-n'
);

$output = implode(', ', array_map(
    function ($v, $k) {
        if(is_array($v)){
            return $k.'[]='.implode('&'.$k.'[]=', $v);
        }else{
            return $k.'='.$v;
        }
    }, 
    $input, 
    array_keys($input)
));

or:

$output = implode(', ', array_map(
    function ($v, $k) { return sprintf("%s='%s'", $k, $v); },
    $input,
    array_keys($input)
));

If g++ still gives error Try using:

g++ file.c -lstdc++

Look at this post: What is __gxx_personality_v0 for?

Make sure -lstdc++ is at the end of the command. If you place it at the beginning (i.e. before file.c), you still can get this same error.

I'm pretty sure the syntax for this in python is:

user_input1 = raw_input("Enter Name: ")
user_input2 = raw_input("Enter Value: ")
info = (user_input1, user_input2)

once set, tuples cannot be changed.

If the Path is omitted the file will be saved automaticaly in the current directory. Try something like this:

ActiveWorkbook.SaveAs "Filename.xslx"

In your database what is the type of "IDNO"? You may need to escape the sql here:

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

setTimeout() function it's use to delay a process in JavaScript.

In angular v10 I did something like this, first created a master.scss file and included the following variables:

master.scss file:

$theme: blue;

$button_color: red;

$label_color: gray;

Then I imported the master.scss file in my style.scss at the top:

style.scss file:

@use './master' as m;

Make sure you import the master.scss at the top.

m is an alias for the namespace;

Use @use instead of @import according to the official docs below:

https://sass-lang.com/documentation/at-rules/import

Then in your styles.scss file you can use any variable which is defined in master.scss like below:

someClass {

   backgroud-color: m.$theme;

   color: m.$button_color;

}

Hope it 'll help...

Happy Coding :)

Make sure you coerce the object id to an integer if you test for strict equality:

var result = $.grep(data, function(e, i) { 
  return +e.id !== id;
});

Demo

If you use script to navigate to the page, use the open method with the target _blank to open a new window / tab:

<img src="..." alt="..." onclick="window.open('anotherpage.html', '_blank');" />

However, if you want search engines to find the page, you should just wrap the image in a regular link instead.

string Email = txtEmail.Text;
if (Email.IsValidEmail())
{
   //use code here

public static bool IsValidEmail(this string email)
{
  string pattern = @"^(?!\.)(""([^""\r\\]|\\[""\r\\])*""|" + @"([-a-z0-9!#$%&'*+/=?^_`{|}~]|(?<!\.)\.)*)(?<!\.)" + @"@[a-z0-9][\w\.-]*[a-z0-9]\.[a-z][a-z\.]*[a-z]$";    
  var regex = new Regex(pattern, RegexOptions.IgnoreCase);    
  return regex.IsMatch(email);
}

Try to replace 'w' for 'iw'. For example:

SELECT to_char(to_date(TRANSDATE, 'dd-mm-yyyy'), 'iw') as weeknumber from YOUR_TABLE;

The error is here:

hasLetter("a",words[]);

You are passing the first item of words, instead of the array.

Instead, pass the array to the function:

hasLetter("a",words);

Problem solved!

Here's a breakdown of what the problem was:

I'm guessing in your browser (chrome throws a different error), words[] == words[0], so when you call hasLetter("a",words[]);, you are actually calling hasLetter("a",words[0]);. So, in essence, you are passing the first item of words to your function, not the array as a whole.

Of course, because words is just an empty array, words[0] is undefined. Therefore, your function call is actually:

hasLetter("a", undefined);

which means that, when you try to access d[ascii], you are actually trying to access undefined[0], hence the error.

If you only want to verify that issuer of UserCert.pem is actually Intermediate.pem do the following (example uses: OpenSSL 1.1.1):

openssl verify -no-CAfile -no-CApath -partial_chain -trusted Intermediate.pem UserCert.pem

and you will get:

UserCert.pem: OK

or

UserCert.pem: verification failed

I have worked a bit on a simple algorithm to compare contents of two objects and return an intelligible list of difference. Thought I would share. It borrows some ideas for jQuery, namely the map function implementation and the object and array type checking.

It returns a list of "diff objects", which are arrays with the diff info. It's very simple.

Here it is:

// compare contents of two objects and return a list of differences
// returns an array where each element is also an array in the form:
// [accessor, diffType, leftValue, rightValue ]
//
// diffType is one of the following:
//   value: when primitive values at that index are different
//   undefined: when values in that index exist in one object but don't in 
//              another; one of the values is always undefined
//   null: when a value in that index is null or undefined; values are
//         expressed as boolean values, indicated wheter they were nulls
//   type: when values in that index are of different types; values are 
//         expressed as types
//   length: when arrays in that index are of different length; values are
//           the lengths of the arrays
//

function DiffObjects(o1, o2) {
    // choose a map() impl.
    // you may use $.map from jQuery if you wish
    var map = Array.prototype.map?
        function(a) { return Array.prototype.map.apply(a, Array.prototype.slice.call(arguments, 1)); } :
        function(a, f) { 
            var ret = new Array(a.length), value;
            for ( var i = 0, length = a.length; i < length; i++ ) 
                ret[i] = f(a[i], i);
            return ret.concat();
        };

    // shorthand for push impl.
    var push = Array.prototype.push;

    // check for null/undefined values
    if ((o1 == null) || (o2 == null)) {
        if (o1 != o2)
            return [["", "null", o1!=null, o2!=null]];

        return undefined; // both null
    }
    // compare types
    if ((o1.constructor != o2.constructor) ||
        (typeof o1 != typeof o2)) {
        return [["", "type", Object.prototype.toString.call(o1), Object.prototype.toString.call(o2) ]]; // different type

                // prop exists in o2 but not in o1

We had this problem years ago before I had joined and had in place a solution that used local storage for user and environment information. Angular 1.0 days to be exact. We were formerly dynamically creating a js file at runtime that would then place the generated api urls into a global variable. We're a little more OOP driven these days and don't use local storage for anything.

I created a better solution for both determining environment and api url creation.

How does this differ?

The app will not load unless the config.json file is loaded. It uses factory functions to create a higher degree of SOC. I could encapsulate this into a service, but I never saw any reason when the only similarity between the different sections of the file are that they exist together in the file. Having a factory function allows me to pass the function directly into a module if it's capable of accepting a function. Last, I have an easier time setting up InjectionTokens when factory functions are available to utilize.

Downsides?

You're out of luck using this setup (and most of the other answers) if the module you want to configure doesn't allow a factory function to be passed into either forRoot() or forChild(), and there's no other way to configure the package by using a factory function.

Instructions

1. Using fetch to retrieve a json file, I store the object in window and raise a custom event. - remember to install whatwg-fetch and add it to your polyfills.ts for IE compatibility
2. Have an event listener listening for the custom event.
3. The event listener receives the event, retrieves the object from window to pass to an observable, and clears out what was stored in window.
4. Bootstrap Angular

-- This is where my solution starts to really differ --

5. Create a file exporting an interface whose structure represents your config.json -- it really helps with type consistency and the next section of code requires a type, and don't specify {} or any when you know you can specify something more concrete
6. Create the BehaviorSubject that you will pass the parsed json file into in step 3.
7. Use factory functions to reference the different sections of your config to maintain SOC
8. Create InjectionTokens for the providers needing the result of your factory functions

-- and/or --

9. Pass the factory functions directly into the modules capable of accepting a function in either its forRoot() or forChild() methods.

-- main.ts

I check window["environment"] is not populated before creating an event listener to allow the possiblilty of a solution where window["environment"] is populated by some other means before the code in main.ts ever executes.

import { enableProdMode } from '@angular/core';
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { AppModule } from './app/app.module';
import { configurationSubject } from './app/utils/environment-resolver';

var configurationLoadedEvent = document.createEvent('Event');
configurationLoadedEvent.initEvent('config-set', true, true);
fetch("../../assets/config.json")
.then(result => { return result.json(); })
.then(data => {
  window["environment"] = data;
  document.dispatchEvent(configurationLoadedEvent);
}, error => window.location.reload());

/*
  angular-cli only loads the first thing it finds it needs a dependency under /app in main.ts when under local scope. 
  Make AppModule the first dependency it needs and the rest are done for ya. Event listeners are 
  ran at a higher level of scope bypassing the behavior of not loading AppModule when the 
  configurationSubject is referenced before calling platformBrowserDynamic().bootstrapModule(AppModule)

  example: this will not work because configurationSubject is the first dependency the compiler realizes that lives under 
  app and will ONLY load that dependency, making AppModule an empty object.

  if(window["environment"])
  {
    if (window["environment"].production) {
      enableProdMode();
    }
    configurationSubject.next(window["environment"]);
    platformBrowserDynamic().bootstrapModule(AppModule)
    .catch(err => console.log(err));
  }
*/
if(!window["environment"]) {
  document.addEventListener('config-set', function(e){
    if (window["environment"].production) {
      enableProdMode();
    }
    configurationSubject.next(window["environment"]);
    window["environment"] = undefined;
    platformBrowserDynamic().bootstrapModule(AppModule)
    .catch(err => console.log(err));
  });
}

--- environment-resolvers.ts

I assign a value to the BehaviorSubject using window["environment"] for redundancy. You could devise a solution where your config is preloaded already and window["environment"] is already populated by the time any of your Angular's app code is ran, including the code in main.ts

import { BehaviorSubject } from "rxjs";
import { IConfig } from "../config.interface";

const config = <IConfig>Object.assign({}, window["environment"]);
export const configurationSubject = new BehaviorSubject<IConfig>(config);
export function resolveEnvironment() {
  const env = configurationSubject.getValue().environment;
  let resolvedEnvironment = "";
  switch (env) {
 // case statements for determining whether this is dev, test, stage, or prod
  }
  return resolvedEnvironment;
}

export function resolveNgxLoggerConfig() {
  return configurationSubject.getValue().logging;
}

-- app.module.ts - Stripped down for easier understanding

Fun fact! Older versions of NGXLogger required you to pass in an object into LoggerModule.forRoot(). In fact, the LoggerModule still does! NGXLogger kindly exposes LoggerConfig which you can override allowing you to use a factory function for setup.

import { resolveEnvironment, resolveNgxLoggerConfig, resolveSomethingElse } from './environment-resolvers';
import { LoggerConfig } from 'ngx-logger';
@NgModule({
    modules: [
        SomeModule.forRoot(resolveSomethingElse)
    ],
    providers:[
        {
            provide: ENVIRONMENT,
            useFactory: resolveEnvironment
        },
        { 
            provide: LoggerConfig,
            useFactory: resolveNgxLoggerConfig
        }
    ]
})
export class AppModule

Addendum

How did I solve the creation of my API urls?

I wanted to be able to understand what each url did via a comment and wanted typechecking since that's TypeScript's greatest strength compared to javascript (IMO). I also wanted to create an experience for other devs to add new endpoints, and apis that was as seamless as possible.

I created a class that takes in the environment (dev, test, stage, prod, "", and etc) and passed this value to a series of classes[1-N] whose job is to create the base url for each API collection. Each ApiCollection is responsible for creating the base url for each collection of APIs. Could be our own APIs, a vendor's APIs, or even an external link. That class will pass the created base url into each subsequent api it contains. Read the code below to see a bare bones example. Once setup, it's very simple for another dev to add another endpoint to an Api class without having to touch anything else.

TLDR; basic OOP principles and lazy getters for memory optimization

@Injectable({
    providedIn: 'root'
})
export class ApiConfig {
    public apis: Apis;

    constructor(@Inject(ENVIRONMENT) private environment: string) {
        this.apis = new Apis(environment);
    }
}

export class Apis {
    readonly microservices: MicroserviceApiCollection;

    constructor(environment: string) {
        this.microservices = new MicroserviceApiCollection(environment);
    }
}

export abstract class ApiCollection {
  protected domain: any;

  constructor(environment: string) {
      const domain = this.resolveDomain(environment);
      Object.defineProperty(ApiCollection.prototype, 'domain', {
          get() {
              Object.defineProperty(this, 'domain', { value: domain });
              return this.domain;
          },
          configurable: true
      });
  }
}

export class MicroserviceApiCollection extends ApiCollection {
  public member: MemberApi;

  constructor(environment) {
      super(environment);
      this.member = new MemberApi(this.domain);
  }

  resolveDomain(environment: string): string {
      return `https://subdomain${environment}.actualdomain.com/`;
  }
}

export class Api {
  readonly base: any;

  constructor(baseUrl: string) {
      Object.defineProperty(this, 'base', {
          get() {
              Object.defineProperty(this, 'base',
              { value: baseUrl, configurable: true});
              return this.base;
          },
          enumerable: false,
          configurable: true
      });
  }

  attachProperty(name: string, value: any, enumerable?: boolean) {
      Object.defineProperty(this, name,
      { value, writable: false, configurable: true, enumerable: enumerable || true });
  }
}

export class MemberApi extends Api {

  /**
  * This comment will show up when referencing this.apiConfig.apis.microservices.member.memberInfo
  */
  get MemberInfo() {
    this.attachProperty("MemberInfo", `${this.base}basic-info`);
    return this.MemberInfo;
  }

  constructor(baseUrl: string) {
    super(baseUrl + "member/api/");
  }
}

For readability, I restructured the query... starting with the apparent top-most level being Table1, which then ties to Table3, and then table3 ties to table2. Much easier to follow if you follow the chain of relationships.

Now, to answer your question. You are getting a large count as the result of a Cartesian product. For each record in Table1 that matches in Table3 you will have X * Y. Then, for each match between table3 and Table2 will have the same impact... Y * Z... So your result for just one possible ID in table 1 can have X * Y * Z records.

This is based on not knowing how the normalization or content is for your tables... if the key is a PRIMARY key or not..

Ex:
Table 1       
DiffKey    Other Val
1          X
1          Y
1          Z

Table 3
DiffKey   Key    Key2  Tbl3 Other
1         2      6     V
1         2      6     X
1         2      6     Y
1         2      6     Z

Table 2
Key    Key2   Other Val
2      6      a
2      6      b
2      6      c
2      6      d
2      6      e

So, Table 1 joining to Table 3 will result (in this scenario) with 12 records (each in 1 joined with each in 3). Then, all that again times each matched record in table 2 (5 records)... total of 60 ( 3 tbl1 * 4 tbl3 * 5 tbl2 )count would be returned.

So, now, take that and expand based on your 1000's of records and you see how a messed-up structure could choke a cow (so-to-speak) and kill performance.

SELECT
      COUNT(*)
   FROM
      Table1 
         INNER JOIN Table3
            ON Table1.DifferentKey = Table3.DifferentKey
            INNER JOIN Table2
               ON Table3.Key =Table2.Key
               AND Table3.Key2 = Table2.Key2 

While calling/invoking your programme you can use this command : java [-options] className [args...]
in place of [-options] provide more memory e.g -Xmx1024m or more. but this is just a workaround, u have to change ur parsing mechanism.

One more solution when you want to use data from any sell ( in the key C3)

=SUMIF(Sheet6!M:M;CONCATENATE("<";TEXT(C3;"dd.mm.yyyy"));Sheet6!L:L)

I had issues with the page reloading but was able to avoid that with routerlink=".":

<a routerLink="." (click)="myFunction()">My Function</a>

I received inspiration from the Angular Material docs on buttons: https://material.angular.io/components/button/examples

If you don't want to use WMI, I can suggest systeminfo.exe. But, there may be a better way to do that.

(systeminfo | Select-String 'Total Physical Memory:').ToString().Split(':')[1].Trim()

My project use ButterKnife and Retro lambda, setting JavaVersion.VERSION_1_8 will not work. It always blames at ButterKnife static interface function until I found this Migrate from Retrolambda

TL;DR

Just add JavaVersion.VERSION_1_8 and completely REMOVE retrolambda from your project. It will build successfully.

You need to store all of the extra rows in the files in your dictionary, not just one of them:

dict1 = {row[0]: row[1:] for row in r}
...
dict2 = {row[0]: row[1:] for row in r}

Then, since the values in the dictionaries are lists, you need to just concatenate the lists together:

w.writerows([[key] + dict1.get(key, []) + dict2.get(key, []) for key in keys])

I had the same issue and correct answer above did not work for me. What I did to resolve it was to go to Build Path->Configure Build Path and under the source tab I removed all the sources (which only had one source) and reconfigured them from there. I ended up removing the project from eclipse and import the maven project again in order to clear up the error.

SQL self-join simply is a normal join which is used to join a table to itself.

Example:

Select *
FROM Table t1, Table t2
WHERE t1.Id = t2.ID

This seems like the easiest (but not most robust) way to me. Simply compute the sum from row 6 to the maximum allowed row number, as specified by Excel. According to this site, the maximum is currently 1048576, so the following should work for you:

=sum(c6:c1048576)

For more robust solutions, see the other answers.

You can't do it with just CSS, but you can do it with Javascript, and (optionally) jQuery.

If you want to do it without jQuery:

<script>
    window.onload = function() {
        var anchors = document.getElementsByTagName('a');
        for(var i = 0; i < anchors.length; i++) {
            var anchor = anchors[i];
            anchor.onclick = function() {
                alert('ho ho ho');
            }
        }
    }
</script>

And to do it without jQuery, and only on a specific class (ex: hohoho):

<script>
    window.onload = function() {
        var anchors = document.getElementsByTagName('a');
        for(var i = 0; i < anchors.length; i++) {
            var anchor = anchors[i];
            if(/\bhohoho\b/).match(anchor.className)) {
                anchor.onclick = function() {
                    alert('ho ho ho');
                }
            }
        }
    }
</script>

If you are okay with using jQuery, then you can do this for all anchors:

<script>
    $(document).ready(function() {
        $('a').click(function() {
            alert('ho ho ho');
        });
    });
</script>

And this jQuery snippet to only apply it to anchors with a specific class:

<script>
    $(document).ready(function() {
        $('a.hohoho').click(function() {
            alert('ho ho ho');
        });
    });
</script>

On CentoS with cPanel installed my logs were in:

/usr/local/apache/logs/error_log

To watch: tail -f /usr/local/apache/logs/error_log

Comparing two objects of the same type using LINQ and Reflection. NB! This is basically a rewrite of the solution from Jon Skeet, but with a more compact and modern syntax. It should also generate slightly more effecticve IL.

It goes something like this:

public bool ReflectiveEquals(LocalHdTicket serverTicket, LocalHdTicket localTicket)
  {
     if (serverTicket == null && localTicket == null) return true;
     if (serverTicket == null || localTicket == null) return false;

     var firstType = serverTicket.GetType();
     // Handle type mismatch anyway you please:
     if(localTicket.GetType() != firstType) throw new Exception("Trying to compare two different object types!");

     return !(from propertyInfo in firstType.GetProperties() 
              where propertyInfo.CanRead 
              let serverValue = propertyInfo.GetValue(serverTicket, null) 
              let localValue = propertyInfo.GetValue(localTicket, null) 
              where !Equals(serverValue, localValue) 
              select serverValue).Any();
  }

Try using asort().

From documentation:

asort - Sort an array and maintain index association

Description:

bool asort ( array &$array [, int $sort_flags = SORT_REGULAR ] )

This function sorts an array such that array indices maintain their correlation with the array elements they are associated with. This is used mainly when sorting associative arrays where the actual element order is significant.

Nothing helped until I found this solution : https://stackoverflow.com/a/39068538/3995091

In Android SDK, the build tools with the correct version where shown as installed, but still I got the same error saying they couldn't be found. When I used the above solution, I found out they were indeed not installed, although Android SDK thought they were. Installing them solved it for me.

Checkout their documentation

From the looks of it you could do the following on your docker-compose.yml

volumes:
    - ./:/app

Where ./ is the host directory, and /app is the target directory for the containers.

    if (cache) { setHtmlStorage('cache_name', data, 30); }

}

My solution: open app on Android studio.

Check sdk and clean App, after rebuild I had fixed this problem by following suggestions of Android Studio. finally run app with react-native run-android/ios

I solved this problem by adding C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework.NETFramework\v4.0\System.Runtime.Serialization.dll in the reference

Another simple way is to use a tuple:

// Declare a tuple type
let x: [string, number];
// Initialize it
x = ["hello", 10];
// Access elements
console.log("First: " + x["0"] + " Second: " + x["1"]);

Output:

First: hello Second: 10

Admitting you want to use some smtp server, you can do:

export SUBJECT=some_subject
export smtp=somehost:someport
export EMAIL=someaccount@somedomain
echo "some message" | mailx -s "$SUBJECT" "$EMAIL"

Change somehost, someport, and someaccount@somedomain to actual values that you would use. No encryption and no authentication is performed in this example.

Click on servers tab in eclipse and then double click on the server listed there. Select the port tab in the config page opened.Change the port to any other ports.Restart the server.

What you can try to do is get the transformation Matrix from the animation before you stop it and inspect the Matrix contents to get the position values you are looking for.

Here are the api's you should look into

public boolean getTransformation (long currentTime, Transformation outTransformation)

public Matrix getMatrix ()

public void getValues (float[] values)

So for example (some pseudo code. I have not tested this):

Transformation outTransformation = new Transformation();
myAnimation.getTransformation(currentTime, outTransformation);
Matrix transformationMatrix = outTransformation.getMatrix();
float[] matrixValues = new float[9];
transformationMatrix.getValues(matrixValues);
float transX = matrixValues[Matrix.MTRANS_X];
float transY = matrixValues[Matrix.MTRANS_Y];

If the list is sorted, you can use a binary search. If not, then there is no better way.

If you're doing this a lot, it would almost certainly be worth your while to sort the list the first time. Since you can't modify the classes, you would have to use a Comparator to do the sorting and searching.

Best answer doesn't work for me. I needed ssh:// from the beggining.

If you need to read all values from a section in properties file in a simple manner:

Your config.cfg file layout :

[SECTION_NAME]  
key1 = value1  
key2 = value2  

You code:

   import configparser

   config = configparser.RawConfigParser()
   config.read('path_to_config.cfg file')
    
   details_dict = dict(config.items('SECTION_NAME'))

This will give you a dictionary where keys are same as in config file and their corresponding values.

details_dict is :

{'key1':'value1', 'key2':'value2'}

Now to get key1's value : details_dict['key1']

Putting it all in a method which reads sections from config file only once(the first time the method is called during a program run).

def get_config_dict():
    if not hasattr(get_config_dict, 'config_dict'):
        get_config_dict.config_dict = dict(config.items('SECTION_NAME'))
    return get_config_dict.config_dict

Now call the above function and get the required key's value :

config_details = get_config_dict()
key_1_value = config_details['key1'] 

Generic Multi Section approach:

[SECTION_NAME_1]  
key1 = value1  
key2 = value2  

[SECTION_NAME_2]  
key1 = value1  
key2 = value2

Extending the approach mentioned above, reading section by section automatically and then accessing by section name followed by key name.

def get_config_section():
    if not hasattr(get_config_section, 'section_dict'):
        get_config_section.section_dict = collections.defaultdict()
        
        for section in config.sections():
            get_config_section.section_dict[section] = dict(config.items(section))
    
    return get_config_section.section_dict

To access:

config_dict = get_config_section()

port = config_dict['DB']['port'] 

(here 'DB' is a section name in config file and 'port' is a key under section 'DB'.)

In PS 7, you can use ConvertFrom-SecureString and -AsPlainText:

 $UnsecurePassword = ConvertFrom-SecureString -SecureString $SecurePassword -AsPlainText

https://docs.microsoft.com/en-us/powershell/module/microsoft.powershell.security/ConvertFrom-SecureString?view=powershell-7#parameters

ConvertFrom-SecureString
           [-SecureString] <SecureString>
           [-AsPlainText]
           [<CommonParameters>]

You can loop through all of the checkboxes by writing $(':checkbox').each(...).

If I understand your question correctly, you're looking for the following code:

var str = "";

$(':checkbox').each(function() {
    str += this.checked ? "1," : "0,";
});

str = str.substr(0, str.length - 1);    //Remove the trailing comma

This code will loop through all of the checkboxes and add either 1, or 0, to a string.

Here is an even simpler solution using base graphics and alpha-blending (which does not work on all graphics devices):

set.seed(42)
p1 <- hist(rnorm(500,4))                     # centered at 4
p2 <- hist(rnorm(500,6))                     # centered at 6
plot( p1, col=rgb(0,0,1,1/4), xlim=c(0,10))  # first histogram
plot( p2, col=rgb(1,0,0,1/4), xlim=c(0,10), add=T)  # second

The key is that the colours are semi-transparent.

Edit, more than two years later: As this just got an upvote, I figure I may as well add a visual of what the code produces as alpha-blending is so darn useful:

I'd start by completely filling in the Notification. Here is a sample project demonstrating the use of startForeground().

Supervised learning

Applications in which the training data comprises examples of the input vectors along with their corresponding target vectors are known as supervised learning problems.

Unsupervised learning

In other pattern recognition problems, the training data consists of a set of input vectors x without any corresponding target values. The goal in such unsupervised learning problems may be to discover groups of similar examples within the data, where it is called clustering

I think Amith Koujalgi is correct but also, in cases where the webservice responses are in JSON then it might be more useful to see the results in a clean JSON format instead of a very long string. Just add | grep }| python -mjson.tool to the end of curl commands here is two examples:

GET approach with JSON result

curl -i -H "Accept: application/json" http://someHostName/someEndpoint | grep }| python -mjson.tool 

POST approach with JSON result

curl -X POST  -H "Accept: Application/json" -H "Content-Type: application/json" http://someHostName/someEndpoint -d '{"id":"IDVALUE","name":"Mike"}' | grep }| python -mjson.tool

The easiest way I've found to place objects on the left is using FlowLayout.

JPanel panel = new JPanel(new FlowLayout(FlowLayout.LEFT));

adding a component normally to this panel will place it on the left

def f(x) -> 123:
    return x

My summary:

1. Simply -> is introduced to get developers to optionally specify the return type of the function. See Python Enhancement Proposal 3107

2. This is an indication of how things may develop in future as Python is adopted extensively - an indication towards strong typing - this is my personal observation.

3. You can specify types for arguments as well. Specifying return type of the functions and arguments will help in reducing logical errors and improving code enhancements.

4. You can have expressions as return type (for both at function and parameter level) and the result of the expressions can be accessed via annotations object's 'return' attribute. annotations will be empty for the expression/return value for lambda inline functions.

One way to do this is to use String.Substring together with String.IndexOf:

int index = str.IndexOf('-');
string sub;
if (index >= 0)
{
    sub = str.Substring(0, index);
}
else
{
    sub = ... // handle strings without the dash
}

Starting at position 0, return all text up to, but not including, the dash.

Probably the machine or web.config in prod has the settings in the configuration; you probably won't need the proxy tag.

<system.net>
    <defaultProxy useDefaultCredentials="true" >
        <proxy usesystemdefault="False"
               proxyaddress="http://<ProxyLocation>:<port>"
               bypassonlocal="True"
               autoDetect="False" />
    </defaultProxy>
</system.net>

If it's just running (not a daemon) then just use Ctrl-C.

If it's daemonized then you could try:

$ ps aux | grep node
you   PID  1.5  0.2  44172  8260 pts/2    S    15:25   0:00 node app.js
$ kill -2 PID

Where PID is replaced by the number in the output of ps.

REST is not a specific web service but a design concept (architecture) for managing state information. The seminal paper on this was Roy Thomas Fielding's dissertation (2000), "Architectural Styles and the Design of Network-based Software Architectures" (available online from the University of California, Irvine).

First read Ryan Tomayko's post How I explained REST to my wife; it's a great starting point. Then read Fielding's actual dissertation. It's not that advanced, nor is it long (six chapters, 180 pages)! (I know you kids in school like it short).

EDIT: I feel it's pointless to try to explain REST. It has so many concepts like scalability, visibility (stateless) etc. that the reader needs to grasp, and the best source for understanding those are the actual dissertation. It's much more than POST/GET etc.

At times, if we forget the

return self.cleaned_data 

in the clean function of django forms, we will not have any data though the form.is_valid() will return True.

Here's a little thing I use just to get the registered paths in express 4.x

app._router.stack          // registered routes
  .filter(r => r.route)    // take out all the middleware
  .map(r => r.route.path)  // get all the paths

in my case I was using below dependency

<dependency>
    <groupId>com.jcraft</groupId>
    <artifactId>jsch</artifactId>
    <version>0.1.42</version>
</dependency> 

and getting the same exception of Auth fail, but updated dependency to below version and problem get resolved.

You might implement your class model by composition, having the book object have a map of chapter objects contained within it (map chapter number to chapter object). Your search function could be given a list of books into which to search by asking each book to search its chapters. The book object would then iterate over each chapter, invoking the chapter.search() function to look for the desired key and return some kind of index into the chapter. The book's search() would then return some data type which could combine a reference to the book and some way to reference the data that it found for the search. The reference to the book could be used to get the name of the book object that is associated with the collection of chapter search hits.

Find id for row N Then get the top M rows that have an id greater than or equal to that

declare @N as int
set @N = 2
declare @M as int
set @M = 3

declare @Nid as int

set @Nid = max(id)
from
  (select top @N *
from MyTable
order by id)

select top @M *
from MyTable
where id >= @Nid
order by id

Something like that ... but I've made some assumptions here (e.g. you want to order by id)

I recently ran into this issue for a different reason: I was running some tests synchronously using jest -i, and it would just timeout. For whatever reasoning, running the same tests using jest --runInBand (even though -i is meant to be an alias) doesn't time out.

Maybe this will help someone ¯\_(:/)_/¯

On OSX using the current Chrome build (2/20/2020, 79.0.3945.130), you can:

Click on the 'i' info icon on the left side of address bar.

Click Site Settings

Scroll down to Insecure content

Change it from Blocked (Default) to Allow

Reload the page and try your action again.

In my example i just change it in selected cell

    for index, row in result.iterrows():
        if np.isnan(row['weight']):
            result.at[index, 'weight'] = 0.0

'result' is a dataField with column 'weight'

var str = 'test343',
    isNumeric = /^[-+]?(\d+|\d+\.\d*|\d*\.\d+)$/;

isNumeric.test(str);

it's answered, but it could be done with a fancy 'map/reduce' use, e.g.:

def find_key(value, dictionary):
    return reduce(lambda x, y: x if x is not None else y,
                  map(lambda x: x[0] if x[1] == value else None, 
                      dictionary.iteritems()))

There is another solution: Create your own dynamic enumeration class. Means you have a struct and some function to create a new enumeration, which stores the elements in a struct and each element has a string for the name. You also need some type to store a individual elements, functions to compare them and so on. Here is an example:

#include <stdarg.h>
#include <stdbool.h>
#include <stddef.h>
#include <stdio.h>
#include <stdlib.h>
#include <string.h>


struct Enumeration_element_T
{
  size_t index;
  struct Enumeration_T *parrent;
  char *name;
};

struct Enumeration_T
{
  size_t len;
  struct Enumeration_element_T elements[];
};
  


void enumeration_delete(struct Enumeration_T *self)
{
  if(self)
  {
    while(self->len--)
    {
      free(self->elements[self->len].name);
    }
    free(self);
  }
}

struct Enumeration_T *enumeration_create(size_t len,...)
{
  //We do not check for size_t overflows, but we should.
  struct Enumeration_T *self=malloc(sizeof(self)+sizeof(self->elements[0])*len);
  if(!self)
  {
    return NULL;
  }
  self->len=0;
  va_list l; 
  va_start(l,len);
  for(size_t i=0;i<len;i++)
  {
    const char *name=va_arg(l,const char *);
    self->elements[i].name=malloc(strlen(name)+1);
    if(!self->elements[i].name)
    {
      enumeration_delete(self);
      return NULL;
    }
    strcpy(self->elements[i].name,name);
    self->len++;
  }
  return self;
}


bool enumeration_isEqual(struct Enumeration_element_T *a,struct Enumeration_element_T *b)
{
  return a->parrent==b->parrent && a->index==b->index;
}

bool enumeration_isName(struct Enumeration_element_T *a, const char *name)
{
  return !strcmp(a->name,name);
}

const char *enumeration_getName(struct Enumeration_element_T *a)
{
  return a->name;
}

struct Enumeration_element_T *enumeration_getFromName(struct Enumeration_T *self, const char *name)
{
  for(size_t i=0;i<self->len;i++)
  {
    if(enumeration_isName(&self->elements[i],name))
    {
      return &self->elements[i];
    }
  }
  return NULL;
}
  
struct Enumeration_element_T *enumeration_get(struct Enumeration_T *self, size_t index)
{
  return &self->elements[index];
}

size_t enumeration_getCount(struct Enumeration_T *self)
{
  return self->len;
}

bool enumeration_isInRange(struct Enumeration_T *self, size_t index)
{
  return index<self->len;
}



int main(void)
{
  struct Enumeration_T *weekdays=enumeration_create(7,"Sunday","Monday","Tuesday","Wednesday","Thursday","Friday","Saturday");
  if(!weekdays)
  {
    return 1;
  }
    
  printf("Please enter the day of the week (0 to 6)\n");
  size_t j = 0;
  if(scanf("%zu",&j)!=1)
  {
    enumeration_delete(weekdays);
    return 1;
  }
  // j=j%enumeration_getCount(weekdays); //alternative way to make sure j is in range
  if(!enumeration_isInRange(weekdays,j))
  {
    enumeration_delete(weekdays);
    return 1;
  }

  struct Enumeration_element_T *day=enumeration_get(weekdays,j);
  

  printf("%s\n",enumeration_getName(day));
  
  enumeration_delete(weekdays);

  return 0;
}

The functions of enumeration should be in their own translation unit, but i combined them here to make it simpler.

The advantage is that this solution is flexible, follows the DRY principle, you can store information along with each element, you can create new enumerations during runtime and you can add new elements during runtime. The disadvantage is that this is complex, needs dynamic memory allocation, can't be used in switch-case, needs more memory and is slower. The question is if you should not use a higher level language in cases where you need this.

You may also want to use hasOwnProperty in the loop.

for (var prop in obj) {
    if (obj.hasOwnProperty(prop)) {
        switch (prop) {
            // obj[prop] has the value
        }
    }
}

node.js is single-threaded which means your script will block whether you want it or not. Remember that V8 (Google's Javascript engine that node.js uses) compiles Javascript into machine code which means that most basic operations are really fast and looping through an object with 100 keys would probably take a couple of nanoseconds?

However, if you do a lot more inside the loop and you don't want it to block right now, you could do something like this

switch (prop) {
    case 'Timestamp':
        setTimeout(function() { ... }, 5);
        break;
    case 'Start_Value':
        setTimeout(function() { ... }, 10);
        break;
}

If your loop is doing some very CPU intensive work, you will need to spawn a child process to do that work or use web workers.

The suggestion to use listdir is a good one. The direct answer to your question in Python 2 is root, dirs, files = os.walk(dir_name).next().

The equivalent Python 3 syntax is root, dirs, files = next(os.walk(dir_name))

Use escape characters for example this code:

var message = "I want to learn \"c#\"";
Console.WriteLine(message);

will output:

I want to learn "c#"

Here's a slightly improved version of illerucis's code for returning a list of all permutations of a string s with distinct characters (not necessarily in lexicographic sort order), without using itertools:

def get_perms(s, i=0):
    """
    Returns a list of all (len(s) - i)! permutations t of s where t[:i] = s[:i].
    """
    # To avoid memory allocations for intermediate strings, use a list of chars.
    if isinstance(s, str):
        s = list(s)

    # Base Case: 0! = 1! = 1.
    # Store the only permutation as an immutable string, not a mutable list.
    if i >= len(s) - 1:
        return ["".join(s)]

    # Inductive Step: (len(s) - i)! = (len(s) - i) * (len(s) - i - 1)!
    # Swap in each suffix character to be at the beginning of the suffix.
    perms = get_perms(s, i + 1)
    for j in range(i + 1, len(s)):
        s[i], s[j] = s[j], s[i]
        perms.extend(get_perms(s, i + 1))
        s[i], s[j] = s[j], s[i]
    return perms

For the 24-hour time, you need to use HH24 instead of HH.

For the 12-hour time, the AM/PM indicator is written as A.M. (if you want periods in the result) or AM (if you don't). For example:

SELECT invoice_date,
       TO_CHAR(invoice_date, 'DD-MM-YYYY HH24:MI:SS') "Date 24Hr",
       TO_CHAR(invoice_date, 'DD-MM-YYYY HH:MI:SS AM') "Date 12Hr"
  FROM invoices
;

For more information on the format models you can use with TO_CHAR on a date, see http://docs.oracle.com/cd/E16655_01/server.121/e17750/ch4datetime.htm#NLSPG004.

You can also use google-collections (guava) Joiner class if you want to customize the print format

I'm not qualified to comment on logging for .Net, since my bread and butter is Java, but we've had a migration in our logging over the last 8 years you may find a useful analogy to your question.

We started with a Singleton logger that was used by every thread within the JVM, and set the logging level for the entire process. This resulted in huge logs if we had to debug even a very specific part of the system, so lesson number one is to segment your logging.

Our current incarnation of the logger allows multiple instances with one defined as the default. We can instantiate any number of child loggers that have different logging levels, but the most useful facet of this architecture is the ability to create loggers for individual packages and classes by simply changing the logging properties. Lesson number two is to create a flexible system that allows overriding its behavior without changing code.

We are using the Apache commons-logging library wrapped around Log4J.

Hope this helps!

* Edit *

After reading Jeffrey Hantin's post below, I realized that I should have noted what our internal logging wrapper has actually become. It's now essentially a factory and is strictly used to get a working logger using the correct properties file (which for legacy reasons hasn't been moved to the default position). Since you can specify the logging configuration file on command line now, I suspect it will become even leaner and if you're starting a new application, I'd definitely agree with his statement that you shouldn't even bother wrapping the logger.

function is_array_assoc($foo) {
    if (is_array($foo)) {
        return (count(array_filter(array_keys($foo), 'is_string')) > 0);
    }
    return false;
}

you must stop another running app involved with especial database table ... like running java API in other module or other project is not terminated .. so terminate running.

To me was better hardcoding "example.com" as string, so I need less rules, even you can use it to redirect from .org to .com or similar too:

<IfModule mod_rewrite.c>
  RewriteEngine On
  RewriteCond %{HTTP_HOST} !^example\.com$ [NC]
  RewriteRule ^ https://example.com%{REQUEST_URI} [L,NE,R=301]
</IfModule>

With Entity Framework 6.1, you can now do this:

[Index("IX_FirstAndSecond", 1, IsUnique = true)]
public int FirstColumn { get; set; }

[Index("IX_FirstAndSecond", 2, IsUnique = true)]
public int SecondColumn { get; set; }

The second parameter in the attribute is where you can specify the order of the columns in the index.
More information: MSDN

As another person just mentioned, it's a base64 encoded string. In the past, I've used this website to decode it:

http://www.motobit.com/util/base64-decoder-encoder.asp

You can try the Anthem library.

Using @"User_Agent" simply causes a custom header to appear in the GET request.

User_agent: Foobar/1.0\r\n
User-Agent: Mozilla/5.0 (iPhone; U; CPU iPhone OS 3_1_2 like Mac OS X; en-us) AppleWebKit/528.18 (KHTML, like Gecko) Mobile/7D11\r\n

The above is what appears in the dissected HTTP packet, essentially confirming what Sfjava was quoting from that forum. It's interesting to note that "User-Agent" gets turned into "User_agent."

This solution will accept only integers and nothing but integers.

def is_number(s):
    while s.isdigit() == False:
        s = raw_input("Enter only numbers: ")
    return int(s)


# Your program starts here    
user_input = is_number(raw_input("Enter a number: "))

I found your question while searching for information with SQLite and Java. Just thought I'd add my answer which I also posted on my blog.

I have been coding in Java for a while now. I have also known about SQLite but never used it… Well I have used it through other applications but never in an app that I coded. So I needed it for a project this week and it's so simple use!

I found a Java JDBC driver for SQLite. Just add the JAR file to your classpath and import java.sql.*

His test app will create a database file, send some SQL commands to create a table, store some data in the table, and read it back and display on console. It will create the test.db file in the root directory of the project. You can run this example with java -cp .:sqlitejdbc-v056.jar Test.

package com.rungeek.sqlite;

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.Statement;

public class Test {
    public static void main(String[] args) throws Exception {
        Class.forName("org.sqlite.JDBC");
        Connection conn = DriverManager.getConnection("jdbc:sqlite:test.db");
        Statement stat = conn.createStatement();
        stat.executeUpdate("drop table if exists people;");
        stat.executeUpdate("create table people (name, occupation);");
        PreparedStatement prep = conn.prepareStatement(
            "insert into people values (?, ?);");

        prep.setString(1, "Gandhi");
        prep.setString(2, "politics");
        prep.addBatch();
        prep.setString(1, "Turing");
        prep.setString(2, "computers");
        prep.addBatch();
        prep.setString(1, "Wittgenstein");
        prep.setString(2, "smartypants");
        prep.addBatch();

        conn.setAutoCommit(false);
        prep.executeBatch();
        conn.setAutoCommit(true);

        ResultSet rs = stat.executeQuery("select * from people;");
        while (rs.next()) {
            System.out.println("name = " + rs.getString("name"));
            System.out.println("job = " + rs.getString("occupation"));
        }
        rs.close();
        conn.close();
    }
  }

Had similar error with the same result with Gradle and was able to solve it by following:

//compile 'org.slf4j:slf4j-api:1.7.1'
compile group: 'org.apache.logging.log4j', name: 'log4j-api', version: '2.1'
compile group: 'org.apache.logging.log4j', name: 'log4j-core', version: '2.1'
compile group: 'org.apache.logging.log4j', name: 'log4j-slf4j-impl', version: '2.1'

Out-commented line is the one which caused the error output. I believe you can transfer this to Maven.

Slicing

Python slicing is an incredibly fast operation, and it's a handy way to quickly access parts of your data.

Slice notation to get the last nine elements from a list (or any other sequence that supports it, like a string) would look like this:

num_list[-9:]

When I see this, I read the part in the brackets as "9th from the end, to the end." (Actually, I abbreviate it mentally as "-9, on")

Explanation:

The full notation is

sequence[start:stop:step]

But the colon is what tells Python you're giving it a slice and not a regular index. That's why the idiomatic way of copying lists in Python 2 is

list_copy = sequence[:]

And clearing them is with:

del my_list[:]

(Lists get list.copy and list.clear in Python 3.)

Give your slices a descriptive name!

You may find it useful to separate forming the slice from passing it to the list.__getitem__ method (that's what the square brackets do). Even if you're not new to it, it keeps your code more readable so that others that may have to read your code can more readily understand what you're doing.

However, you can't just assign some integers separated by colons to a variable. You need to use the slice object:

last_nine_slice = slice(-9, None)

The second argument, None, is required, so that the first argument is interpreted as the start argument otherwise it would be the stop argument.

You can then pass the slice object to your sequence:

>>> list(range(100))[last_nine_slice]
[91, 92, 93, 94, 95, 96, 97, 98, 99]

islice

islice from the itertools module is another possibly performant way to get this. islice doesn't take negative arguments, so ideally your iterable has a __reversed__ special method - which list does have - so you must first pass your list (or iterable with __reversed__) to reversed.

>>> from itertools import islice
>>> islice(reversed(range(100)), 0, 9)
<itertools.islice object at 0xffeb87fc>

islice allows for lazy evaluation of the data pipeline, so to materialize the data, pass it to a constructor (like list):

>>> list(islice(reversed(range(100)), 0, 9))
[99, 98, 97, 96, 95, 94, 93, 92, 91]

COUNT is part of pig see the manual

LOGS= LOAD 'log';
LOGS_GROUP= GROUP LOGS ALL;
LOG_COUNT = FOREACH LOGS_GROUP GENERATE COUNT(LOGS);

All Perl's "special variables" are listed in the perlvar documentation page.

Since there is only 1 numeric value to isolate in your string, I would endorse and personally use filter_var() with FILTER_SANITIZE_NUMBER_INT.

echo filter_var($string, FILTER_SANITIZE_NUMBER_INT);

A whackier technique which works because there is only 1 numeric value AND the only characters that come before the integer are alphanumeric, colon, or spaces is to use ltrim() with a character mask then cast the remaining string as an integer.

Demo

$string = "In My Cart : 11 items";
echo (int)ltrim($string, 'A..z: ');
// 11

If for some reason there was more than one integer value and you wanted to grab the first one, then regex would be a direct technique.

Demo

echo preg_match('/\d+/', $string, $m) ? $m[0] : '';

Most of the space you have available is reserved by the OS. The best and easy fix is to move your apps to external storage. This will free up a lot of space for you.

I created an alternative directive that doesn't have ngApp's limitations. It's called ngModule. This is what you code would look like when you use it:

<!DOCTYPE html>
<html>
    <head>
        <script src="angular.js"></script>
        <script src="angular.ng-modules.js"></script>
        <script>
          var moduleA = angular.module("MyModuleA", []);
          moduleA.controller("MyControllerA", function($scope) {
              $scope.name = "Bob A";
          });

          var moduleB = angular.module("MyModuleB", []);
          moduleB.controller("MyControllerB", function($scope) {
              $scope.name = "Steve B";
          });
        </script>
    </head>
    <body>
        <div ng-modules="MyModuleA, MyModuleB">
            <h1>Module A, B</h1>
            <div ng-controller="MyControllerA">
                {{name}}
            </div>
            <div ng-controller="MyControllerB">
                {{name}}
            </div>
        </div>

        <div ng-module="MyModuleB">
            <h1>Just Module B</h1>
            <div ng-controller="MyControllerB">
                {{name}}
            </div>
        </div>
    </body>
</html>

You can get the source code at:

http://www.simplygoodcode.com/2014/04/angularjs-getting-around-ngapp-limitations-with-ngmodule/

It's essentially the same code used internally by AngularJS without the limitations.

You can add a 10px padding on the sides to your body element if all it's children are rows

body {
  padding: 0 10px;
}

if your HTML markup looks something like this:

<body>
    <div class="row"></div>
    <div class="row"></div>
    <div class="row"></div>
</body>

The rows have a 10 px negative margin. That's what's causing the overflow. If you add 10px padding to the body, they will cancel each other out.

I send you an example with swiftmailer:

parameters.yml

recipients: [email1, email2, email3]

services:

your_service_name:
        class: your_namespace
        arguments: ["%recipients%"]

the class of the service:

protected $recipients;

public function __construct($recipients)
{
    $this->recipients = $recipients;
}

Use PropertyInfo.PropertyType to get the type of the property.

public bool ValidateData(object data)
{
    foreach (PropertyInfo propertyInfo in data.GetType().GetProperties())
    {
        if (propertyInfo.PropertyType == typeof(string))
        {
            string value = propertyInfo.GetValue(data, null);

            if value is not OK
            {
                return false;
            }
        }
    }            

    return true;
}

If the image is part of the layout it might be "View.VISIBLE" but that doesn't mean it's within the confines of the visible screen. If that's what you're after; this will work:

Rect scrollBounds = new Rect();
scrollView.getHitRect(scrollBounds);
if (imageView.getLocalVisibleRect(scrollBounds)) {
    // imageView is within the visible window
} else {
    // imageView is not within the visible window
}

On the "How to do it" part:

I think the introduction to ScalaTest does good job of illustrating different styles of unit tests.

On the "When to do it" part:

Unit testing is not only for testing. By doing unit testing you also force the design of the software into something that is unit testable. Many people are of the opinion that this design is for the most part Good Design(TM) regardless of other benefits from testing.

So one reason to do unit test is to force your design into something that hopefully will be easier to maintain that what it would be had you not designed it for unit testing.

this seems to work fine :

dataframe.axes[0].tolist()

They both seems to navigate to the given webpage and quoting @matt answer:

navigate().to() and get() do exactly the same thing.

Single-Page Applications are an exception to this.

The difference between these two methods comes not from their behavior, but from the behavior in the way the application works and how browser deal with it.

navigate().to() navigates to the page by changing the URL like doing forward/backward navigation.

Whereas, get() refreshes the page to changing the URL.

So, in cases where application domain changes, both the method behaves similarly. That is, page is refreshed in both the cases. But, in single-page applications, while navigate().to() do not refreshes the page, get() do.

Moreover, this is the reason browser history is getting lost when get() is used due to application being refreshed.

Try svn revert filename for every file you don't need and haven't yet committed. Or alternatively do svn revert -R folder for the problematic folder and then re-do the operation with correct ignoring configuration.

From the documentation:

 you can undo any scheduling operations:

$ svn add mistake.txt whoops
A         mistake.txt
A         whoops
A         whoops/oopsie.c

$ svn revert mistake.txt whoops
Reverted mistake.txt
Reverted whoops

Working my way through Fluent Python (Ramalho) - highly recommended. List comprehension one-ish-liners inspired by Chapter 2:

onlyascii = ''.join([s for s in data if ord(s) < 127])
onlymatch = ''.join([s for s in data if s in
              'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz'])

Check out the use of the supressionCommentFilter at http://checkstyle.sourceforge.net/config_filters.html#SuppressionCommentFilter. You'll need to add the module to your checkstyle.xml

<module name="SuppressionCommentFilter"/>

and it's configurable. Thus you can add comments to your code to turn off checkstyle (at various levels) and then back on again through the use of comments in your code. E.g.

//CHECKSTYLE:OFF
public void someMethod(String arg1, String arg2, String arg3, String arg4) {
//CHECKSTYLE:ON

Or even better, use this more tweaked version:

<module name="SuppressionCommentFilter">
    <property name="offCommentFormat" value="CHECKSTYLE.OFF\: ([\w\|]+)"/>
    <property name="onCommentFormat" value="CHECKSTYLE.ON\: ([\w\|]+)"/>
    <property name="checkFormat" value="$1"/>
</module>

which allows you to turn off specific checks for specific lines of code:

//CHECKSTYLE.OFF: IllegalCatch - Much more readable than catching 7 exceptions
catch (Exception e)
//CHECKSTYLE.ON: IllegalCatch

*Note: you'll also have to add the FileContentsHolder:

<module name="FileContentsHolder"/>

See also

<module name="SuppressionFilter">
    <property name="file" value="docs/suppressions.xml"/>
</module>

under the SuppressionFilter section on that same page, which allows you to turn off individual checks for pattern matched resources.

So, if you have in your checkstyle.xml:

<module name="ParameterNumber">
   <property name="id" value="maxParameterNumber"/>
   <property name="max" value="3"/>
   <property name="tokens" value="METHOD_DEF"/>
</module>

You can turn it off in your suppression xml file with:

<suppress id="maxParameterNumber" files="YourCode.java"/>

Another method, now available in Checkstyle 5.7 is to suppress violations via the @SuppressWarnings java annotation. To do this, you will need to add two new modules (SuppressWarningsFilter and SuppressWarningsHolder) in your configuration file:

<module name="Checker">
   ...
   <module name="SuppressWarningsFilter" />
   <module name="TreeWalker">
       ...
       <module name="SuppressWarningsHolder" />
   </module>
</module> 

Then, within your code you can do the following:

@SuppressWarnings("checkstyle:methodlength")
public void someLongMethod() throws Exception {

or, for multiple suppressions:

@SuppressWarnings({"checkstyle:executablestatementcount", "checkstyle:methodlength"})
public void someLongMethod() throws Exception {

NB: The "checkstyle:" prefix is optional (but recommended). According to the docs the parameter name have to be in all lowercase, but practice indicates any case works.

String s = "-1139627840";
BigInteger bg1 = new BigInteger(s);
System.out.println(bg1.abs());

Alternatively:

int i = -123;
System.out.println(Math.abs(i));

Your model is @Messages, change it to @message.

To change it like you should use migration:

def change   rename_table :old_table_name, :new_table_name end 

Of course do not create that file by hand but use rails generator:

rails g migration ChangeMessagesToMessage 

That will generate new file with proper timestamp in name in 'db dir. Then run:

rake db:migrate 

And your app should be fine since then.

i'll leave this here since i will need to use it later. It's a source for a small binary compatible tool that will work equally well in assembly, C and C++.

    GetErrorMessageW = (int (*)(DWORD, LPWSTR, DWORD))GetProcAddress (
        GetModuleHandle("GetErrorMessageLib.dll"),
        "GetErrorMessageW"
    );        

    GetErrorMessageA(33, result1, sizeof(result1));
    GetErrorMessageW(33, result2, sizeof(result2));

    puts(result1);
    _putws(result2);

    return 0;
}

regular use case(assumes error code is valid, otherwise -1 return check is needed):

#include <stdio.h>
#include "GetErrorMessage.h"
#include <stdio.h>

int main(int argc, char **argv)
{
    char result1[260];
    wchar_t result2[260];

    GetErrorMessageA(33, result1, sizeof(result1));
    puts(result1);

    GetErrorMessageW(33, result2, sizeof(result2));
    _putws(result2);

    return 0;
}

example using with assembly gnu as in MinGW32(again, assumed that error code is valid, otherwise -1 check is needed).

    .global _WinMain@16

    .section .text
_WinMain@16:
    // eax = LoadLibraryA("GetErrorMessageLib.dll")
    push $sz0
    call _LoadLibraryA@4 // stdcall, no cleanup needed

    // eax = GetProcAddress(eax, "GetErrorMessageW")
    push $sz1
    push %eax
    call _GetProcAddress@8 // stdcall, no cleanup needed

    // (*eax)(errorCode, szErrorMessage)
    push $200
    push $szErrorMessage
    push errorCode       
    call *%eax // cdecl, cleanup needed
    add $12, %esp

    push $szErrorMessage
    call __putws // cdecl, cleanup needed
    add $4, %esp

    ret $16

    .section .rodata
sz0: .asciz "GetErrorMessageLib.dll"    
sz1: .asciz "GetErrorMessageW"
errorCode: .long 33

    .section .data

No need for jQuery, use:

JSON.stringify(countries); 

First declare your list properly, separated by commas. You can get the unique values by converting the list to a set.

mylist = ['nowplaying', 'PBS', 'PBS', 'nowplaying', 'job', 'debate', 'thenandnow']
myset = set(mylist)
print(myset)

If you use it further as a list, you should convert it back to a list by doing:

mynewlist = list(myset)

Another possibility, probably faster would be to use a set from the beginning, instead of a list. Then your code should be:

output = set()
for x in trends:
    output.add(x)
print(output)

As it has been pointed out, sets do not maintain the original order. If you need that, you should look for an ordered set implementation (see this question for more).

try this to close the connection:

socket.close();

and if you want to open it again:

socket.connect();

jQuery's .html() can be used for setting and getting the contents of matched non empty elements (innerHTML).

var contents = $(element).html();
$(element).html("insert content into element");

As shown in this example, you can apply a background to a canvas element through CSS and this background will not be considered part the image, e.g. when fetching the contents through toDataURL().

Here are the contents of the example, for Stack Overflow posterity:

<!DOCTYPE HTML>
<html><head>
  <meta charset="utf-8">
  <title>Canvas Background through CSS</title>
  <style type="text/css" media="screen">
    canvas, img { display:block; margin:1em auto; border:1px solid black; }
    canvas { background:url(lotsalasers.jpg) }
  </style>
</head><body>
<canvas width="800" height="300"></canvas>
<img>
<script type="text/javascript" charset="utf-8">
  var can = document.getElementsByTagName('canvas')[0];
  var ctx = can.getContext('2d');
  ctx.strokeStyle = '#f00';
  ctx.lineWidth   = 6;
  ctx.lineJoin    = 'round';
  ctx.strokeRect(140,60,40,40);
  var img = document.getElementsByTagName('img')[0];
  img.src = can.toDataURL();
</script>
</body></html>

It's been quite some time but it's a core part of the stdlib and has dozens of potential methods so I think it's useful to have some benchmarks for the different suggestions and include the numpy method which can be by far the fastest.

import random
from timeit import timeit
import numpy as np

l = [random.random() for i in range(10**4)]
l[10**4 - 100] = 5

# method 1
def fun1(l:list, x:int, e = -1) -> int:
    return [[i for i,elem in enumerate(l) if elem == x] or [e]][0]

# method 2
def fun2(l:list, x:int, e = -1) -> int:
    for i,elem in enumerate(l):
        if elem == x:
            return i
    else:
        return e

# method 3
def fun3(l:list, x:int, e = -1) -> int:
    try:
        idx = l.index(x)
    except ValueError:
        idx = e
    return idx

# method 4
def fun4(l:list, x:int, e = -1) -> int:
    return l.index(x) if x in l else e

l2 = np.array(l)
# method 5
def fun5(l:list or np.ndarray, x:int, e = -1) -> int:
    res = np.where(np.equal(l, x))
    if res[0].any():
        return res[0][0]
    else:        
        return e


if __name__ == "__main__":
    print("Method 1:")
    print(timeit(stmt = "fun1(l, 5)", number = 1000, globals = globals()))
    print("")
    print("Method 2:")
    print(timeit(stmt = "fun2(l, 5)", number = 1000, globals = globals()))
    print("")
    print("Method 3:")
    print(timeit(stmt = "fun3(l, 5)", number = 1000, globals = globals()))
    print("")
    print("Method 4:")
    print(timeit(stmt = "fun4(l, 5)", number = 1000, globals = globals()))
    print("")
    print("Method 5, numpy given list:")
    print(timeit(stmt = "fun5(l, 5)", number = 1000, globals = globals()))
    print("")
    print("Method 6, numpy given np.ndarray:")
    print(timeit(stmt = "fun5(l2, 5)", number = 1000, globals = globals()))
    print("")

When run as main, this results in the following printout on my machine indicating time in seconds to complete 1000 trials of each function:

Method 1: 0.7502102799990098

Method 2: 0.7291318440002215

Method 3: 0.24142152300009911

Method 4: 0.5253471979995084

Method 5, numpy given list: 0.5045417560013448

Method 6, numpy given np.ndarray: 0.011147511999297421

Of course the question asks specifically about lists so the best solution is to use the try-except method, however the speed improvements (at least 20x here compared to try-except) offered by using the numpy data structures and operators instead of python data structures is significant and if building something on many arrays of data that is performance critical then the author should try to use numpy throughout to take advantage of the superfast C bindings. (CPython interpreter, other interpreter performances may vary)

Btw, the reason Method 5 is much slower than Method 6 is because numpy first has to convert the given list to it's own numpy array, so giving it a list doesn't break it it just doesn't fully utilise the speed possible.

Here is how I do this. I create a table with a thead and tbody tags. And then add a click event to the tbody element by id.

<script>
    document.getElementById("mytbody").click = clickfunc;
    function clickfunc(e) {
        // to find what td element has the data you are looking for
        var tdele = e.target.parentNode.children[x].innerHTML;
        // to find the row
        var trele = e.target.parentNode;
    }
</script>
<table>
    <thead>
        <tr>
            <th>Header 1</th>
            <th>Header 2</th>
        </tr>
    </thead>
    <tbody id="mytbody">
        <tr><td>Data Row</td><td>1</td></tr>
        <tr><td>Data Row</td><td>2</td></tr>
        <tr><td>Data Row</td><td>3</td></tr>
    </tbody>
</table>

Use the span tag

<style>
    .redText
    {
        color:red;
    }
    .blackText
    {
        color:black;
        font-weight:bold;
    }
</style>

<span class="redText">My Name is:</span>&nbsp;<span class="blackText">Tintincute</span>

It's also a good idea to avoid inline styling. Use a custom CSS class instead.

At https://github.com/golang/go/issues/44196 randall77 suggested

time.Now().Sub(time.Unix(0,0)).Milliseconds()

which exploits the fact that Go's time.Duration already have Milliseconds method.

is you want fix XSS on input element? you can encode string before output to input field

PHP:

$str = htmlentities($str);

C#:

str = WebUtility.HtmlEncode(str);

after that output value direct to input field:

<input type="text" value="<?php echo $str" />

One notice. On Windows, place your _curlrc in '%APPDATA%' or '%USERPROFILE%\Application Data'.

In XAMPP installation directory, open %XAMPP_HOME%/php/php.ini file. Uncomment the following line: extension=php_curl.dll

PS: If that doesn't work then check whether %XAMPP_HOME%/php/ext/php_curl.dll file exist or not.

Try:

Column(
 mainAxisAlignment: MainAxisAlignment.center,
 crossAxisAlignment: CrossAxisAlignment.center,
 children:children...)

Issues were:

1. IPV6 enabled
2. Wrong DNS server

Here is how I fixed it:

IPV6 Disabling

• Open Terminal
• Type su and enter to log in as the super user
• Enter the root password
• Type cd /etc/modprobe.d/ to change directory to /etc/modprobe.d/
• Type vi disableipv6.conf to create a new file there
• Press Esc + i to insert data to file
• Type install ipv6 /bin/true on the file to avoid loading IPV6 related modules
• Type Esc + : and then wq for save and exit
• Type reboot to restart fedora
• After reboot open terminal and type lsmod | grep ipv6
• If no result, it means you properly disabled IPV6

Add Google DNS server

• Open Terminal
• Type su and enter to log in as the super user
• Enter the root password
• Type cat /etc/resolv.conf to check what DNS server your Fedora using. Mostly this will be your Modem IP address.
• Now we have to Find a powerful DNS server. Luckily there is a open DNS server maintain by Google.
• Go to this page and find out what are the "Google Public DNS IP addresses"
• Today those are 8.8.8.8 and 8.8.4.4. But in future those may change.
• Type vi /etc/resolv.conf to edit the resolv.conf file
• Press Esc + i for insert data to file
• Comment all the things in the file by inserting # at the begin of the each line. Do not delete anything because can be useful in future.

• Type below two lines in the file

  nameserver 8.8.8.8
  nameserver 8.8.4.4

  -Type Esc + : and then wq for save and exit

• Now you are done and everything works fine (Not necessary to restart).
• But every time when you restart the computer your /etc/resolv.conf will be replaced by default. So I'll let you find a way to avoid that.

Here is my blog post about this: http://codeketchup.blogspot.sg/2014/07/how-to-fix-curl-6-could-not-resolve.html

Here is an example function that I wrote to do this based upon the answers above and my own use case:

def label_vector_to_one_hot_vector(vector, one_hot_size=10):
    """
    Use to convert a column vector to a 'one-hot' matrix

    Example:
        vector: [[2], [0], [1]]
        one_hot_size: 3
        returns:
            [[ 0.,  0.,  1.],
             [ 1.,  0.,  0.],
             [ 0.,  1.,  0.]]

    Parameters:
        vector (np.array): of size (n, 1) to be converted
        one_hot_size (int) optional: size of 'one-hot' row vector

    Returns:
        np.array size (vector.size, one_hot_size): converted to a 'one-hot' matrix
    """
    squeezed_vector = np.squeeze(vector, axis=-1)

    one_hot = np.zeros((squeezed_vector.size, one_hot_size))

    one_hot[np.arange(squeezed_vector.size), squeezed_vector] = 1

    return one_hot

label_vector_to_one_hot_vector(vector=[[2], [0], [1]], one_hot_size=3)

Essentially it means you don't have the index you are trying to reference. For example:

df = pd.DataFrame()
df['this']=np.nan
df['my']=np.nan
df['data']=np.nan
df['data'][0]=5 #I haven't yet assigned how long df[data] should be!
print(df)

will give me the error you are referring to, because I haven't told Pandas how long my dataframe is. Whereas if I do the exact same code but I DO assign an index length, I don't get an error:

df = pd.DataFrame(index=[0,1,2,3,4])
df['this']=np.nan
df['is']=np.nan
df['my']=np.nan
df['data']=np.nan
df['data'][0]=5 #since I've properly labelled my index, I don't run into this problem!
print(df)

Hope that answers your question!

For me when trying to open a link :

Uri uri = Uri.parse("https://www.facebook.com/abc/");
                Intent intent = new Intent(Intent.ACTION_VIEW, uri);
                startActivity(intent);

I got the same error android.content.ActivityNotFoundException: No Activity found to handle Intent

The problem was because i didnt have any app that can open URLs (i.e. browsers) installed in my phone. So after Installing a browser the problem was solved.

*Lesson : Make sure there is at least one app which handles the intent you are calling *

I used below code and it's working fine for me. :

let jsonText = "{\"userName\":\"Bhavsang\"}"
var dictonary:NSDictionary?
    
if let data = jsonText.dataUsingEncoding(NSUTF8StringEncoding) {
        
     do {
            dictonary =  try NSJSONSerialization.JSONObjectWithData(data, options: [.allowFragments]) as? [String:AnyObject]
        
            if let myDictionary = dictonary
              {
                  print(" User name is: \(myDictionary["userName"]!)")
              }
            } catch let error as NSError {
            
            print(error)
         }
}

I don't think React-Router provides this support. The documentation mentions

A < Redirect > sets up a redirect to another route in your application to maintain old URLs.

You could try using something like React-Redirect instead

Another way to accomplish this is with the jq "--arg" flag. Using the original example:

#!/bin/sh

#this works ***
projectID=$(cat file.json | jq -r '.resource[] | 
select(.username=="[email protected]") | .id')
echo "$projectID"

[email protected]

# Use --arg to pass the variable to jq. This should work:
projectID=$(cat file.json | jq --arg EMAILID $EMAILID -r '.resource[] 
| select(.username=="$EMAILID") | .id')
echo "$projectID"

See here, which is where I found this solution: https://github.com/stedolan/jq/issues/626

... or if you really want to use NOT IN you can use

SELECT * FROM match WHERE id NOT IN ( SELECT id FROM email WHERE id IS NOT NULL)

You can also change the port when starting up:

$ pg_ctl -o "-F -p 5433" start

Or

$ postgres -p 5433

More about this in the manual.

You can also use parseReactHTMLComponent from Jumper Package. Just look at it, it's easy and you don't need to use JSX syntax.

https://codesandbox.io/s/jumper-module-react-simple-parser-3b8c9?file=/src/App.js .

Your code is almost correct. The only issue is the usage of list comprehension.

If you use like: (x[0] for x in lst), it returns a generator object. If you use like: [x[0] for x in lst], it return a list.

When you append the list comprehension output to a list, the output of list comprehension is the single element of the list.

lst = [["a","b","c"], [1,2,3], ["x","y","z"]]
lst2 = []
lst2.append([x[0] for x in lst])
print lst2[0]

lst2 = [['a', 1, 'x']]

lst2[0] = ['a', 1, 'x']

Please let me know if I am incorrect.

this is my working batch

publish-my-website.bat

SET MSBUILD_PATH="C:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise\MSBuild\15.0\Bin"
SET PUBLISH_DIRECTORY="C:\MyWebsitePublished"
SET PROJECT="D:\Github\MyWebSite.csproj"


cd /d %MSBUILD_PATH%
MSBuild %PROJECT%  /p:DeployOnBuild=True /p:DeployDefaultTarget=WebPublish /p:WebPublishMethod=FileSystem /p:DeleteExistingFiles=True /p:publishUrl=%PUBLISH_DIRECTORY%

Note that I installed Visual Studio on server to be able to run MsBuild.exe because the MsBuild.exe in .Net Framework folders don't work.

With C++11 you can now do

struct std::tm tm;
std::istringstream ss("16:35:12");
ss >> std::get_time(&tm, "%H:%M:%S"); // or just %T in this case
std::time_t time = mktime(&tm);

see std::get_time and strftime for reference

The command uptime gives you load averages for the past 1, 5, and 15 minutes.

You could try letting the stream throw an exception on failure:

std::ifstream f;
//prepare f to throw if failbit gets set
std::ios_base::iostate exceptionMask = f.exceptions() | std::ios::failbit;
f.exceptions(exceptionMask);

try {
  f.open(fileName);
}
catch (std::ios_base::failure& e) {
  std::cerr << e.what() << '\n';
}

e.what(), however, does not seem to be very helpful:

• I tried it on Win7, Embarcadero RAD Studio 2010 where it gives "ios_base::failbit set" whereas strerror(errno) gives "No such file or directory."
• On Ubuntu 13.04, gcc 4.7.3 the exception says "basic_ios::clear" (thanks to arne)

If e.what() does not work for you (I don't know what it will tell you about the error, since that's not standardized), try using std::make_error_condition (C++11 only):

catch (std::ios_base::failure& e) {
  if ( e.code() == std::make_error_condition(std::io_errc::stream) )
    std::cerr << "Stream error!\n"; 
  else
    std::cerr << "Unknown failure opening file.\n";
}

I think it's worth answering the generic question "R - test if string contains string" here.

For that, use the grep function.

# example:
> if(length(grep("ab","aacd"))>0) print("found") else print("Not found")
[1] "Not found"
> if(length(grep("ab","abcd"))>0) print("found") else print("Not found")
[1] "found"

If you insist on having this trivial function in pure batch I suggest this:

@echo off

set x=somestring
set n=0
set m=255

:loop
if "!x:~%m%,1!" == "" (
    set /a "m>>=1"
    goto loop
) else (
    set /a n+=%m%+1
    set x=!x:~%m%!
    set x=!x:~1!
    if not "!x!" == "" goto loop
)

echo %n%

PS. You must have delayed variable expansion enabled to run this.

EDIT. Now I have made an improved version:

@echo off

set x=somestring
set n=0

for %%m in (4095 2047 1023 511 255 127 63 31 15 7 3 1 0) do (
    if not "!x:~%%m,1!" == "" (
        set /a n+=%%m+1
        set x=!x:~%%m!
        set x=!x:~1!
        if "!x!" == "" goto done
    )
)

:done
echo %n%

EDIT2. If you have a C compiler or something on your system you can create the programs you need and miss on the fly if they don't exist. This method is very general. Take string length as an example:

@echo off

set x=somestring

if exist strlen.exe goto comp
echo #include "string.h" > strlen.c
echo int main(int argc, char* argv[]) { return strlen(argv[1]); } >> strlen.c
CL strlen.c 

:comp
strlen "%x%"
set n=%errorlevel%
echo %n%

You have to set up PATH, INCLUDE and LIB appropriately. This too can be done on the fly from the batch script. Even if you don't know whether you've got a compiler or don't know where it is you can search for it in your script.
