Programs & Examples On #Compiler theory

This problem is not solved like this, the problem is in the different instances of node, try removing globally create-react-app and then delete the node_modules and package-lock.json from your root user

There is no quick function access to getting/setting cookies, so I came up with the following hack:

var http = require('http');

function parseCookies (request) {
    var list = {},
        rc = request.headers.cookie;

    rc && rc.split(';').forEach(function( cookie ) {
        var parts = cookie.split('=');
        list[parts.shift().trim()] = decodeURI(parts.join('='));
    });

    return list;
}


http.createServer(function (request, response) {

  // To Read a Cookie
  var cookies = parseCookies(request);

  // To Write a Cookie
  response.writeHead(200, {
    'Set-Cookie': 'mycookie=test',
    'Content-Type': 'text/plain'
  });
  response.end('Hello World\n');
}).listen(8124);

console.log('Server running at http://127.0.0.1:8124/');

This will store all cookies into the cookies object, and you need to set cookies when you write the head.

If you're using C#, you can either get all the matches at once (i.e. use Regex.Matches(), which returns a MatchCollection, and check the index of the item: index % 2 != 0).

If you want to find the occurrence to replace it, use one of the overloads of Regex.Replace() that uses a MatchEvaluator (e.g. Regex.Replace(String, String, MatchEvaluator). Here's the code:

using System;
using System.Collections.Generic;
using System.Text;
using System.Text.RegularExpressions;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            string input = "abcdabcd";

            // Replace *second* a with m

            string replacedString = Regex.Replace(
                input,
                "a",
                new SecondOccuranceFinder("m").MatchEvaluator);

            Console.WriteLine(replacedString);
            Console.Read();

        }

        class SecondOccuranceFinder
        {
            public SecondOccuranceFinder(string replaceWith)
            {
                _replaceWith = replaceWith;
                _matchEvaluator = new MatchEvaluator(IsSecondOccurance);
            }

            private string _replaceWith;

            private MatchEvaluator _matchEvaluator;
            public MatchEvaluator MatchEvaluator
            {
                get
                {
                    return _matchEvaluator;
                }
            }

            private int _matchIndex;
            public string IsSecondOccurance(Match m)
            {
                _matchIndex++;
                if (_matchIndex % 2 == 0)
                    return _replaceWith;
                else
                    return m.Value;
            }
        }
    }
}

The following query is useful to delete duplicate rows. The table in this example has ID as an identity column and the columns which have duplicate data are Column1, Column2 and Column3.

DELETE FROM TableName
WHERE  ID NOT IN (SELECT MAX(ID)
                  FROM   TableName
                  GROUP  BY Column1,
                            Column2,
                            Column3
                  /*Even if ID is not null-able SQL Server treats MAX(ID) as potentially
                    nullable. Because of semantics of NOT IN (NULL) including the clause
                    below can simplify the plan*/
                  HAVING MAX(ID) IS NOT NULL) 

The following script shows usage of GROUP BY, HAVING, ORDER BY in one query, and returns the results with duplicate column and its count.

SELECT YourColumnName,
       COUNT(*) TotalCount
FROM   YourTableName
GROUP  BY YourColumnName
HAVING COUNT(*) > 1
ORDER  BY COUNT(*) DESC 

At the end of your for() loop, you can use the savefig() function instead of plt.show() and set the name, dpi and format of your figure.

E.g. 1000 dpi and eps format are quite a good quality, and if you want to save every picture at folder ./ with names 'Sample1.eps', 'Sample2.eps', etc. you can just add the following code:

for fname in glob("./*.txt"):
    # Your previous code goes here
    [...]

    plt.savefig("./{}.eps".format(fname), bbox_inches='tight', format='eps', dpi=1000)

The answer by EdChum provides you with a lot of flexibility but if you just want to concateate strings into a column of list objects you can also:

output_series = df.groupby(['name','month'])['text'].apply(list)

DateTime doesn't have a format. the format only applies when you're turning a DateTime into a string, which happens implicitly you show the value on a form, web page, etc.

Look at where you're displaying the DateTime and set the format there (or amend your question if you need additional guidance).

I tried to do this with Date with native JSON...

function stringify (obj: any) {
  return JSON.stringify(
    obj,
    function (k, v) {
      if (this[k] instanceof Date) {
        return ['$date', +this[k]]
      }
      return v
    }
  )
}

function clone<T> (obj: T): T {
  return JSON.parse(
    stringify(obj),
    (_, v) => (Array.isArray(v) && v[0] === '$date') ? new Date(v[1]) : v
  )
}

What does this say? It says

• There needs to be a unique identifier, better than $date, if you want it more secure.

class Klass {
  static fromRepr (repr: string): Klass {
    return new Klass(...)
  }

  static guid = '__Klass__'

  __repr__ (): string {
    return '...'
  }
}

This is a serializable Klass, with

function serialize (obj: any) {
  return JSON.stringify(
    obj,
    function (k, v) { return this[k] instanceof Klass ? [Klass.guid, this[k].__repr__()] : v }
  )
}

function deserialize (repr: string) {
  return JSON.parse(
    repr,
    (_, v) => (Array.isArray(v) && v[0] === Klass.guid) ? Klass.fromRepr(v[1]) : v
  )
}

I tried to do it with Mongo-style Object ({ $date }) as well, but it failed in JSON.parse. Supplying k doesn't matter anymore...

BTW, if you don't care about libraries, you can use yaml.dump / yaml.load from js-yaml. Just make sure you do it the dangerous way.

It won't work well with WordNet, because WordNet does not contain all english words. Another possibility based on NLTK without enchant is NLTK's words corpus

>>> from nltk.corpus import words
>>> "would" in words.words()
True
>>> "could" in words.words()
True
>>> "should" in words.words()
True
>>> "I" in words.words()
True
>>> "you" in words.words()
True

pep8 was recently added to PyPi.

• pep8 - Python style guide checker
• pep8 is a tool to check your Python code against some of the style conventions in PEP 8.

It is now super easy to check your code against pep8.

See http://pypi.python.org/pypi/pep8

Hope this Helps:

public String getSystemTimeInBelowFormat() {
    String timestamp = new SimpleDateFormat("yyyy-mm-dd 'T' HH:MM:SS.mmm-HH:SS").format(new Date());
    return timestamp;
}

tableColumns

• null for all columns as in SELECT * FROM ...
• new String[] { "column1", "column2", ... } for specific columns as in SELECT column1, column2 FROM ... - you can also put complex expressions here:
  new String[] { "(SELECT max(column1) FROM table1) AS max" } would give you a column named max holding the max value of column1

whereClause

• the part you put after WHERE without that keyword, e.g. "column1 > 5"
• should include ? for things that are dynamic, e.g. "column1=?" -> see whereArgs

whereArgs

• specify the content that fills each ? in whereClause in the order they appear

the others

• just like whereClause the statement after the keyword or null if you don't use it.

Example

String[] tableColumns = new String[] {
    "column1",
    "(SELECT max(column1) FROM table2) AS max"
};
String whereClause = "column1 = ? OR column1 = ?";
String[] whereArgs = new String[] {
    "value1",
    "value2"
};
String orderBy = "column1";
Cursor c = sqLiteDatabase.query("table1", tableColumns, whereClause, whereArgs,
        null, null, orderBy);

// since we have a named column we can do
int idx = c.getColumnIndex("max");

is equivalent to the following raw query

String queryString =
    "SELECT column1, (SELECT max(column1) FROM table1) AS max FROM table1 " +
    "WHERE column1 = ? OR column1 = ? ORDER BY column1";
sqLiteDatabase.rawQuery(queryString, whereArgs);

By using the Where/Bind -Args version you get automatically escaped values and you don't have to worry if input-data contains '.

Unsafe: String whereClause = "column1='" + value + "'";
Safe: String whereClause = "column1=?";

because if value contains a ' your statement either breaks and you get exceptions or does unintended things, for example value = "XYZ'; DROP TABLE table1;--" might even drop your table since the statement would become two statements and a comment:

SELECT * FROM table1 where column1='XYZ'; DROP TABLE table1;--'

using the args version XYZ'; DROP TABLE table1;-- would be escaped to 'XYZ''; DROP TABLE table1;--' and would only be treated as a value. Even if the ' is not intended to do bad things it is still quite common that people have it in their names or use it in texts, filenames, passwords etc. So always use the args version. (It is okay to build int and other primitives directly into whereClause though)

Another easy way to find out if a variable is either list or tuple or generally check variable type would be :

    def islist(obj):

        if ("list" in str(type(obj)) ): return True

        else : return False

You can also do this

SELECT    CONCAT(title, ' ', forename, ' ', surname) AS name
FROM      customer c
LEFT JOIN  (
              SELECT * FROM  customer_data ORDER BY id DESC
          ) customer_data ON (customer_data.customer_id = c.customer_id)
GROUP BY  c.customer_id          
WHERE     CONCAT(title, ' ', forename, ' ', surname) LIKE '%Smith%' 
LIMIT     10, 20;

>>> my_list = ['this\n', 'is\n', 'a\n', 'list\n', 'of\n', 'words\n']
>>> map(str.strip, my_list)
['this', 'is', 'a', 'list', 'of', 'words']

var top = $('html').offset().top;

should do it.

edit: this is the negative of $(document).scrollTop()

refer to http://www.w3schools.com/php/php_mysql_select.asp . If you are a beginner and want to learn, w3schools is a good place.

<?php
    $con=mysqli_connect("localhost","root","YOUR_PHPMYADMIN_PASSWORD","hrmwaitrose");
    // Check connection
    if (mysqli_connect_errno())
      {
      echo "Failed to connect to MySQL: " . mysqli_connect_error();
      }

    $result = mysqli_query($con,"SELECT * FROM employee");

    while($row = mysqli_fetch_array($result))
      {
      echo $row['FirstName'] . " " . $row['LastName']; //these are the fields that you have stored in your database table employee
      echo "<br />";
      }

    mysqli_close($con);
    ?>

You can similarly echo it inside your table

<?php
 echo "<table>";
 while($row = mysqli_fetch_array($result))
          {
          echo "<tr><td>" . $row['FirstName'] . "</td><td> " . $row['LastName'] . "</td></tr>"; //these are the fields that you have stored in your database table employee
          }
 echo "</table>";
 mysqli_close($con);
?>

Building on Peter N's answer, this is an example of how to add (optional) user-specified arguments to pass to Java main for a JavaExec task (since you can't set the 'args' property manually for the reason he cites.)

Add this to the task:

task(runProgram, type: JavaExec) {

  [...]

  if (project.hasProperty('myargs')) {
      args(myargs.split(','))
  }

... and run at the command line like this

% ./gradlew runProgram '-Pmyargs=-x,7,--no-kidding,/Users/rogers/tests/file.txt'

In case you solve a more complex task of logging execution statistics in your code:

public void logExecutionMillis(LocalDateTime start, String callerMethodName) {

  LocalDateTime end = getNow();
  long difference = Duration.between(start, end).toMillis();

  Logger logger = LoggerFactory.getLogger(ProfilerInterceptor.class);

  long millisInDay = 1000 * 60 * 60 * 24;
  long millisInHour = 1000 * 60 * 60;
  long millisInMinute = 1000 * 60;
  long millisInSecond = 1000;

  long days = difference / millisInDay;
  long daysDivisionResidueMillis = difference - days * millisInDay;

  long hours = daysDivisionResidueMillis / millisInHour;
  long hoursDivisionResidueMillis = daysDivisionResidueMillis - hours * millisInHour;

  long minutes = hoursDivisionResidueMillis / millisInMinute;
  long minutesDivisionResidueMillis = hoursDivisionResidueMillis - minutes * millisInMinute;

  long seconds = minutesDivisionResidueMillis / millisInSecond;
  long secondsDivisionResidueMillis = minutesDivisionResidueMillis - seconds * millisInSecond;

  logger.info(
      "\n************************************************************************\n"
          + callerMethodName
          + "() - "
          + difference
          + " millis ("
          + days
          + " d. "
          + hours
          + " h. "
          + minutes
          + " min. "
          + seconds
          + " sec."
          + secondsDivisionResidueMillis
          + " millis).");
}

P.S. Logger can be replaced with simple System.out.println() if you like.

Update: this answer works with both ,Visual Sudio 2017 and 2019

For me it worked by the following three steps:

1. Updating Visual Studio to the latest build.
2. Adding Report / Report Wizard to the Add/New Item menu by:
   • Going to Visual Studio menu Tools/Extensions and Updates
   • Choose Online from the left panel.
   • Search for Microsoft Rdlc Report Designer for Visual Studio
   • Download and install it.

3. Adding Report viewer control by:

   • Going to NuGet Package Manager.

   • Installing Microsoft.ReportingServices.ReportViewerControl.Winforms

   • Go to the folder that contains Microsoft.ReportViewer.WinForms.dll: %USERPROFILE%\.nuget\packages\microsoft.reportingservices.reportviewercontrol.winforms\140.1000.523\lib\net40
   • Drag the Microsoft.ReportViewer.WinForms.dll file and drop it at Visual Studio Toolbox Window.

For WebForms applications:

1. The same.
2. The same.

3. Adding Report viewer control by:

   • Going to NuGet Package Manager.

   • Installing Microsoft.ReportingServices.ReportViewerControl.WebForms

   • Go to the folder that contains Microsoft.ReportViewer.WebForms.dll file: %USERPROFILE%\.nuget\packages\microsoft.reportingservices.reportviewercontrol.webforms\140.1000.523\lib\net40
   • Drag the Microsoft.ReportViewer.WebForms.dll file and drop it at Visual Studio Toolbox Window.

That's all!

I could solve similar problem with System.Net.HTTP by adding assembly reference in app.config of main application.

  <runtime>
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
      <dependentAssembly>
        <assemblyIdentity name="System.Net.Http" publicKeyToken="b03f5f7f11d50a3a" culture="neutral" />
        <bindingRedirect oldVersion="0.0.0.0-4.1.1.1" newVersion="4.0.0.0" />
      </dependentAssembly></runtime>

Prefix is the prefix for url routing. If it's equals to '/' it means it will have no prefix. Then you defined a route with pattern "it should start with /hello".

To create a route for '/' you need to add these lines in your src/Shop/MyShopBundle/Resources/config/routing.yml :

ShopMyShopBundle_homepage:
    pattern:  /
    defaults: { _controller: ShopMyShopBundle:Main:index }

Simple SQL triggered API call without building a code project

I know this is far from perfect or architectural purity, but I had a customer with a short term, critical need to integrate with a third party product via an immature API (no wsdl) I basically needed to call the API when a database event occurred. I was given basic call info - URL, method, data elements and Token, but no wsdl or other start to import into a code project. All recommendations and solutions seemed start with that import.

I used the ARC (Advanced Rest Client) Chrome extension and JaSON to test the interaction with the Service from a browser and refine the call. That gave me the tested, raw call structure and response and let me play with the API quickly. From there, I started trying to generate the wsdl or xsd from the json using online conversions but decided that was going to take too long to get working, so I found cURL (clouds part, music plays). cURL allowed me to send the API calls to a local manager from anywhere. I then broke a few more design rules and built a trigger that queued the DB events and a SQL stored procedure and scheduled task to pass the parameters to cURL and make the calls. I initially had the trigger calling XP_CMDShell (I know, booo) but didn't like the transactional implications or security issues, so switched to the Stored Procedure method.

In the end, DB insert matching the API call case triggers write to Queue table with parameters for API call Stored procedure run every 5 seconds runs Cursor to pull each Queue table entry, send the XP_CMDShell call to the bat file with parameters Bat file contains Curl call with parameters inserted sending output to logs. Works well.

Again, not perfect, but for a tight timeline, and a system used short term, and that can be closely monitored to react to connectivity and unforeseen issues, it worked.

Hope that helps someone struggling with limited API info get a solution going quickly.

Sort the values:

sorted(data.values())

returns

['a','b']

Your method should work fine on a Mac, but on Windows, two additional steps are necessary.

1. Create a new folder in the desired location and name it ".ssh." (note the closing dot - this will vanish, but is required to create a folder beginning with ".")
2. When prompted, use the file path format C:/Users/NAME/.ssh/id_rsa (note no closing dot on .ssh).

Saving the id_rsa key in this location should solve the permission error.

You could use Matcher#start(group) and Matcher#end(group) to build a generic replacement method:

public static String replaceGroup(String regex, String source, int groupToReplace, String replacement) {
    return replaceGroup(regex, source, groupToReplace, 1, replacement);
}

public static String replaceGroup(String regex, String source, int groupToReplace, int groupOccurrence, String replacement) {
    Matcher m = Pattern.compile(regex).matcher(source);
    for (int i = 0; i < groupOccurrence; i++)
        if (!m.find()) return source; // pattern not met, may also throw an exception here
    return new StringBuilder(source).replace(m.start(groupToReplace), m.end(groupToReplace), replacement).toString();
}

public static void main(String[] args) {
    // replace with "%" what was matched by group 1 
    // input: aaa123ccc
    // output: %123ccc
    System.out.println(replaceGroup("([a-z]+)([0-9]+)([a-z]+)", "aaa123ccc", 1, "%"));

    // replace with "!!!" what was matched the 4th time by the group 2
    // input: a1b2c3d4e5
    // output: a1b2c3d!!!e5
    System.out.println(replaceGroup("([a-z])(\\d)", "a1b2c3d4e5", 2, 4, "!!!"));
}

If after the installation curl-dev luarocks does not see the headers:

find /usr -name 'curl.h'
Example: /usr/include/x86_64-linux-gnu/curl/curl.h

luarocks install lua-cURL CURL_INCDIR=/usr/include/x86_64-linux-gnu/

The code above works perfectly with one minor flaw; the resulting file is not saved with a .csv extension. – Tensigh 2 days ago

I added the following to code and it saved my file as a csv. Thanks for this bit of code.It all worked as expected.

ActiveWorkbook.SaveAs Filename:=SaveToDirectory & ThisWorkbook.Name & "-" & WS.Name & ".csv", FileFormat:=xlCSV

Just don't include the columns that you want to use the default value for in your insert statement. For instance:

INSERT INTO table1 (field1, field3) VALUES (5, 10);

...will take the default values for field2 and field4, and assign 5 to field1 and 10 to field3.

I know this is an older post, but I found what worked for me to fix this error was using the IP address of my server instead of using the domain name within my fetch request. So for example:

#(original) var request = new Request('https://davidwalsh.name/demo/arsenal.json');
#use IP instead
var request = new Request('https://0.0.0.0/demo/arsenal.json');

fetch(request).then(function(response) {
    // Convert to JSON
    return response.json();
}).then(function(j) {
    // Yay, `j` is a JavaScript object
    console.log(JSON.stringify(j));
}).catch(function(error) {
    console.log('Request failed', error)
});

LENGTH() does return the string length (just verified). I suppose that your data is padded with blanks - try

SELECT typ, LENGTH(TRIM(t1.typ))
FROM AUTA_VIEW t1;

instead.

As OraNob mentioned, another cause could be that CHAR is used in which case LENGTH() would also return the column width, not the string length. However, the TRIM() approach also works in this case.

Steps I did:

1. Include the angular-cookies.js file in the HTML!

2. Init cookies as being NOT http-only in server-side app.'s:

   app.configure(function(){
      //a bunch of stuff
      app.use(express.cookieSession({secret: 'mySecret', store: store, cookie: cookieSettings}));```
   

3. Then in client-side services.jss I put ['ngCookies'] in like this:

   angular.module('swrp', ['ngCookies']).//etc

4. Then in controller.js, in my function UserLoginCtrl, I have $cookies in there with $scope at the top like so:

   function UserLoginCtrl($scope, $cookies, socket) {

5. Lastly, to get the value of a cookie inside the controller function I did:

   var mySession = $cookies['connect.sess'];

Now you can send that back to the server from the client. Awesome. Wish they would've put this in the Angular.js documentation. I figured it out by just reading the actual code for angular-cookies.js directly.

You just have to read the laravel installation page:

1. Install Composer if not already installed
2. Open a command line and do:

composer global require "laravel/installer"

Inside your htdocs or www directory, use either:

laravel new appName

(this can lead to an error on windows computers while using latest Laravel (1.3.2)) or:

composer create-project --prefer-dist laravel/laravel appName

(this works also on windows) to create a project called "appName".

To use "php artisan xyz" you have to be inside your project root! as artisan is a file php is going to use... Simple as that ;)

You may need read this https://developer.android.com/guide/topics/resources/drawable-resource.html#Shape

and below there is a Note.

Note Every corner must (initially) be provided a corner radius greater than 1, or else no corners are rounded. If you want specific corners to not be rounded, a work-around is to use android:radius to set a default corner radius greater than 1, but then override each and every corner with the values you really want, providing zero ("0dp") where you don't want rounded corners.

You can't. Your only option is to divide this into multiple tables and put the form tag outside of it. You could end up nesting your tables, but this is not recommended:

<table>
  <tr><td><form>
    <table><tr><td>id</td><td>name</td>...</tr></table>
  </form></td></tr>
</table>

I would remove the tables entirely and replace it with styled html elements like divs and spans.

Here is how I would do it if working with a large number of "to remove" values that would take a long time to manually remove.

• -Put Original List in Column A -Put To Remove list in Column B -Select both columns, then "Conditional Formatting"
  -Select "Hightlight Cells Rules" --> "Duplicate Values"
  -The duplicates should be hightlighted in both columns
  -Then select Column A and then "Sort & Filter" ---> "Custom Sort"
  -In the dialog box that appears, select the middle option "Sort On" and pick "Cell Color"
  -Then select the next option "Sort Order" and choose "No Cell Color" "On bottom"
  -All the highlighted cells should be at the top of the list. -Select all the highlighted cells by scrolling down the list, then click delete.

the solution for the given scenerio is:

f = lambda x : x if x == 2 else print("number is not 2")
f(30)  # number is not 2
f(2)   #2

What I normally do is e . (e-space-dot) which gives me a browsable current directory - then I can / - search for name fragments, just like finding a word in a text file. I find that generally good enough, simple and quick.

Try this simple code:

#include <stdio.h>
#include <conio.h>
void main(void)
{ 
    clrscr();
    int a[4], i, b;
    printf("enter nos ");
    for (i = 1; i <= 5; i++) {
        scanf("%d", &a[i]);
    }
    for(i = 1; i <= 5; i++) {
        printf("\n%d", a[i]);
    }

I think what's happening, is that, since the wrapper id is relatively position, it just appears on the same position with the body tag, what you should do, is that you can add a Z-index to the wrapper id.

#wrapper {
margin: auto;
text-align: left;
width: 832px;
position: relative;
padding-top: 27px;
z-index: 99; /* added this line */
 }

This should make layers above the transparent body tag.

Sometimes you want to delete a file whatever the case(whatever the exception occurs ,please do delete the file). For such situations.

public static void DeleteFile(string path)
        {
            if (!File.Exists(path))
            {
                return;
            }

            bool isDeleted = false;
            while (!isDeleted)
            {
                try
                {
                    File.Delete(path);
                    isDeleted = true;
                }
                catch (Exception e)
                {
                }
                Thread.Sleep(50);
            }
        }

Note:An exception is not thrown if the specified file does not exist.

Many answers to this one so far and all of the above seem concrete. I think you'll be safe by using stat as you go along, but OS depending, you may get some inode errors creep up on you. So implementing your own stat call functionality using 64bit to avoid any overflow issues seems fairly compatible.

You can completely handle it in the MySQL query:

SELECT SUM(column_name) FROM table_name;

Using PDO (mysql_query is deprecated)

$stmt = $handler->prepare('SELECT SUM(value) AS value_sum FROM codes');
$stmt->execute();

$row = $stmt->fetch(PDO::FETCH_ASSOC);
$sum = $row['value_sum'];

Or using mysqli:

$result = mysqli_query($conn, 'SELECT SUM(value) AS value_sum FROM codes'); 
$row = mysqli_fetch_assoc($result); 
$sum = $row['value_sum'];

First you will need to install node definitions for Typescript. You can find the definitions file here:

https://github.com/DefinitelyTyped/DefinitelyTyped/blob/master/node/node.d.ts

Once you've got file, just add the reference to your .ts file like this:

/// <reference path="path/to/node.d.ts" />

Then you can code your typescript class that read/writes, using the Node File System module. Your typescript class myClass.ts can look like this:

/// <reference path="path/to/node.d.ts" />

class MyClass {

    // Here we import the File System module of node
    private fs = require('fs');

    constructor() { }

    createFile() {

        this.fs.writeFile('file.txt', 'I am cool!',  function(err) {
            if (err) {
                return console.error(err);
            }
            console.log("File created!");
        });
    }

    showFile() {

        this.fs.readFile('file.txt', function (err, data) {
            if (err) {
                return console.error(err);
            }
            console.log("Asynchronous read: " + data.toString());
        });
    }
}

// Usage
// var obj = new MyClass();
// obj.createFile();
// obj.showFile();

Once you transpile your .ts file to a javascript (check out here if you don't know how to do it), you can run your javascript file with node and let the magic work:

> node myClass.js

One way or another you must tell boto3 in which region you wish the kms client to be created. This could be done explicitly using the region_name parameter as in:

kms = boto3.client('kms', region_name='us-west-2')

or you can have a default region associated with your profile in your ~/.aws/config file as in:

[default]
region=us-west-2

or you can use an environment variable as in:

export AWS_DEFAULT_REGION=us-west-2

but you do need to tell boto3 which region to use.

try using INSTALL_ROOT.

make install INSTALL_ROOT=$INSTALL_DIRECTORY

Completely relative:

<img src="kitten.png"/>

this is a relative path indeed.

Absolute in all respects:

<img src="http://www.foo.com/images/kitten.png"/>

this is a URL, and it can be seen in some way as an absolute path, but it's not representative for this matter.

The difference between relative and absolute paths is that when using relative paths you take as reference the current working directory while with absolute paths you refer to a certain, well known directory. Relative paths are useful when you make some program that has to use resources from certain folders that can be opened using the working directory as a starting point.

Example of relative paths:

• image.png, which is the equivalent to .\image.png (in Windows) or ./image.png (anywhere else). The . explicitly specifies that you're expressing a path relative to the current working directory, but this is implied whenever the path doesn't begin at a root directory (designated with a slash), so you don't have to use it necessarily (except in certain contexts where a default directory (or a list of directories to search) will be applied unless you explicitly specify some directory).

• ..\images\image2.jpg This way you can access resources from directories one step up the folders tree.  The ..\ means you've exited the current folder, entering the directory that contains both the working and images folders.  Again, use \ in Windows and / anywhere else.

Example of absolute paths:

• D:\documents\something.doc
• E:\music\good_music.mp3

and so on.

I had the same problems I solved it. I went to https://www.google.com/recaptcha/admin and clicked on the domain and then went to key settings at the bottom.

There I disabled the the option below Domain Name Validation Verify the origin of reCAPTCHA solution

clicked on save and captcha started working.

I think this has to do with way the server is setup. I am on a shared hosting and just was transferred without notice from Liquidweb to Deluxehosting(as the former sold their share hosting to the latter) and have been having such problems with many issues. I think in this case google is checking the server but it is identifying as shared server name and not my domain. When i uncheck the "verify origin" it starts working. Hope this helps solve the problem for the time being.

So KevZero requested a less kludgy solution, so I came up with the following:

sed -r 's#^\[([0-9]+\.[0-9]+)\](.*)#echo -n "[";echo -n $(date --date="@$(echo "$(grep btime /proc/stat|cut -d " " -f 2)+\1" | bc)" +"%c");echo -n "]";echo -n "\2"#e'

Here's an example:

$ dmesg|tail | sed -r 's#^\[([0-9]+\.[0-9]+)\](.*)#echo -n "[";echo -n $(date --date="@$(echo "$(grep btime /proc/stat|cut -d " " -f 2)+\1" | bc)" +"%c");echo -n "]";echo -n "\2"#e'

If you want it to perform a bit better, put the timestamp from proc into a variable instead :)

In my case, I had to select the "src/main/java" and select the "Run As" menu Just like this, so that "Spring Boot App" would be displayed as here.

Branching off of Mohommad's answer:

str_years = [x for x in range(24)]
#[0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23]

#Or, if you're starting with ints:
int_years = [int(x) for x in str_years]

#Formatted here
form_years = ["%02d" % x for x in int_years]

print(form_years)
#['00', '01', '02', '03', '04', '05', '06', '07', '08', '09', '10', '11', '12', '13', '14', '15', '16', '17', '18', '19', '20', '21', '22', '23']

You can use this simple JavaScript code to make search button to link to a sample search results page. Here I have redirected to '/search' of my home page, If you want to search from Google search engine, You can use "https://www.google.com/search" in form action.

<form action="/search"> Enter your search text: 
<input type="text" id="searchtext" name="q"> &nbsp;
<input onclick="myFunction()" type="submit" value="Search It" />
</form> 
<script> function myFunction() 
{ 
var search = document.getElementById("searchtext").value; 
window.location = '/search?q='+search; 
} 
</script>

Are you using the latest version of bootstrap? I have adapted the html from the Fluid Layout example as shown below. I added a drop down and placed it furthest to the right hand side by adding the pull-right class. When hovering over the drop down menu it is automatically pulled to the left and nothing is hidden - all the menu text is visible. I have not used any custom css.

<div class="navbar navbar-inverse navbar-fixed-top">

lines is a list. re.findall() doesn't take lists.

>>> import re
>>> f = open('README.md', 'r')
>>> lines = f.readlines()
>>> match = re.findall('[A-Z]+', lines)
Traceback (most recent call last):
  File "<input>", line 1, in <module>
  File "/usr/lib/python2.7/re.py", line 177, in findall

From help(file.readlines). I.e. readlines() is for loops/iterating:

readlines(...)
    readlines([size]) -> list of strings, each a line from the file.

To find all uppercase characters in your file:

>>> import re
>>> re.findall('[A-Z]+', open('README.md', 'r').read())
['S', 'E', 'A', 'P', 'S', 'I', 'R', 'C', 'I', 'A', 'P', 'O', 'G', 'P', 'P', 'T', 'V', 'W', 'V', 'D', 'A', 'L', 'U', 'O', 'I', 'L', 'P', 'A', 'D', 'V', 'S', 'M', 'S', 'L', 'I', 'D', 'V', 'S', 'M', 'A', 'P', 'T', 'P', 'Y', 'C', 'M', 'V', 'Y', 'C', 'M', 'R', 'R', 'B', 'P', 'M', 'L', 'F', 'D', 'W', 'V', 'C', 'X', 'S']

This is what I use when passing a multi-select param to another multi-select param.

=SPLIT(JOIN(Parameters!<your param name>.Value,","),",")

You have to sort with a custom comparator based on the value of the entry. Then select all the keys before collecting

countByType.entrySet()
           .stream()
           .sorted((e1, e2) -> e1.getValue().compareTo(e2.getValue())) // custom Comparator
           .map(e -> e.getKey())
           .collect(Collectors.toList());

Use htmlparser2, its way faster and pretty straightforward. Consult this usage example:

https://www.npmjs.org/package/htmlparser2#usage

And the live demo here:

http://demos.forbeslindesay.co.uk/htmlparser2/

Dictionaries in python have no order. You could use a list of tuples as your data structure instead.

d = { 'a': 10, 'b': 20, 'c': 30}
newd = [('a',10), ('b',20), ('c',30)]

Then this code could be used to find the locations of keys with a specific value

locations = [i for i, t in enumerate(newd) if t[0]=='b']

>>> [1]

Adding placeholder attributes from code-behind:

txtFilterTerm.Attributes.Add("placeholder", "Filter" + Filter.Name);

Or

txtFilterTerm.Attributes["placeholder"] = "Filter" + Filter.Name;

Adding placeholder attributes from aspx Page

<asp:TextBox type="text" runat="server" id="txtFilterTerm" placeholder="Filter" />

Or

<input type="text" id="txtFilterTerm" placeholder="Filter"/>

You can fix it that way:

s = "{'username':'dfdsfdsf'}"
j = eval(s)

Using recursion (sometimes asked on interviews)

public int CountDigits(int number)
{
    // In case of negative numbers
    number = Math.Abs(number);

    if (number >= 10)
        return CountDigits(number / 10) + 1;
    return 1;
 }

You also should set border:none to that css class.

let datestring = "2017-02-14 02:16:28"

let formatter = DateFormatter()
formatter.dateStyle = DateFormatter.Style.full
formatter.timeStyle = DateFormatter.Style.full

formatter.dateFormat = "yyyy-MM-dd hh:mm:ss"

let date = formatter.date(from: datestring)
let date2 = formatter.String(from: date)

There is a line in wp-config.php:

define('DB_CHARSET', 'utf8mb4');

If you follow Markouver's / Evster's instructions, don't forget to change this line on production server to

define('DB_CHARSET', 'utf8');

in order to fix broken 4-byte characters

Wrap the Parallel.Foreach into a Task.Run() and instead of the await keyword use [yourasyncmethod].Result

(you need to do the Task.Run thing to not block the UI thread)

Something like this:

var yourForeachTask = Task.Run(() =>
        {
            Parallel.ForEach(ids, i =>
            {
                ICustomerRepo repo = new CustomerRepo();
                var cust = repo.GetCustomer(i).Result;
                customers.Add(cust);
            });
        });
await yourForeachTask;

User johannes told you how to do add existing files to a Git repository in a general situation. Because you talk about Bitbucket, I suggest you do the following:

1. Create a new repository on Bitbucket (you can see a Create button on the top of your profile page) and you will go to this page:

   

2. Fill in the form, click next and then you automatically go to this page:

   

3. Choose to add existing files and you go to this page:

   

4. You use those commands and you upload the existing files to Bitbucket. After that, the files are online.

This also works:

CAST( coulmn_value AS UNSIGNED ) // will return 0 if not numeric string.

for example

SELECT CAST('a123' AS UNSIGNED) // returns 0
SELECT CAST('123' AS UNSIGNED) // returns 123 i.e. > 0

If you want to change a color to single column try this:

 dataGridView1.EnableHeadersVisualStyles = false;
 dataGridView1.Columns[0].HeaderCell.Style.BackColor = Color.Magenta;
 dataGridView1.Columns[1].HeaderCell.Style.BackColor = Color.Yellow;

Maybe this can help you ? git-diff-tree - Compares the content and mode of blobs found via two tree objects

Try mylist[0][0]. This should return the first character.

Wow, everybody is such a pessimist around here. The answer is yes.

It ain't trivial: by the end, we'll have the core function, a supporting struct, a wrapper function, and a macro around the wrapper function. In my work I have a set of macros to automate all this; once you understand the flow it'll be easy for you to do the same.

I've written this up elsewhere, so here's a detailed external link to supplement the summary here: http://modelingwithdata.org/arch/00000022.htm

We'd like to turn

double f(int i, double x)

into a function that takes defaults (i=8, x=3.14). Define a companion struct:

typedef struct {
    int i;
    double x;
} f_args;

Rename your function f_base, and define a wrapper function that sets defaults and calls the base:

double var_f(f_args in){
    int i_out = in.i ? in.i : 8;
    double x_out = in.x ? in.x : 3.14;
    return f_base(i_out, x_out);
}

Now add a macro, using C's variadic macros. This way users don't have to know they're actually populating a f_args struct and think they're doing the usual:

#define f(...) var_f((f_args){__VA_ARGS__});

OK, now all of the following would work:

f(3, 8);      //i=3, x=8
f(.i=1, 2.3); //i=1, x=2.3
f(2);         //i=2, x=3.14
f(.x=9.2);    //i=8, x=9.2

Check the rules on how compound initializers set defaults for the exact rules.

One thing that won't work: f(0), because we can't distinguish between a missing value and zero. In my experience, this is something to watch out for, but can be taken care of as the need arises---half the time your default really is zero.

I went through the trouble of writing this up because I think named arguments and defaults really do make coding in C easier and even more fun. And C is awesome for being so simple and still having enough there to make all this possible.

I had the same issue but the below steps helped me to get out of it.

1. Installing the 'webpack-dev-server' locally (In the project directory as it was not picking from the global installation)

   npm install --save webpack-dev-server

Can verify whether 'webpack-dev-server' folder exists inside node_modules.

2. Running using npx for running directly

npx webpack-dev-server --mode development --config ./webpack.dev.js

npm run start also works fine where your entry in package.json scripts should be like the above like without npx.

In the future (perhaps) you will be able to use :nth-child(an+b of s)

Actually, browser support for the “of” filter is very limited. Only Safari seems to support the syntax.

https://css-tricks.com/almanac/selectors/n/nth-child/

$('.modal.in').modal('hide');

use the above code to hide the backdrop of modal if you are using multiple modal pop in one page.

Another option is to use find and then pass it through sed.

find /path/to/files -type f -exec sed -i 's/oldstring/new string/g' {} \;

Aside from object initializers (usable only in constructor calls), the best you can get is:

var it = Stuff.Elements.Foo;
it.Name = "Bob Dylan";
it.Age = 68;
...

At first I would use http://ruby.railstutorial.org/.

And database.yml is place where you put setup for database your application use - username, password, host - for each database. With new application you dont need to change anything - simply use default sqlite setup.

If you want to load a cmsblock into your template/blockfile/model etc. You can do this as followed. This will render any variables places in the cmsblock

$block  = Mage::getModel('cms/block')
            ->setStoreId(Mage::app()->getStore()->getId())
            ->load('identifier');

$var = array('variable' => 'value', 'other_variable' => 'other value');
/* This will be {{var variable}} and {{var other_variable}} in your CMS block */

$filterModel = Mage::getModel('cms/template_filter');
$filterModel->setVariables($var);

echo $filterModel->filter($block->getContent());

I created a function to generate a form, based on url, target and an object as the POST/GET data and submit method. It supports nested and mixed types within that object, so it can fully replicate any structure you feed it: PHP automatically parses it and returns it as a nested array. However, there is a single restriction: the brackets [ and ] must not be part of any key in the object (like {"this [key] is problematic" : "hello world"}). If someone knows how to escape it properly, please do tell!

Without further ado, here is the source:

You can pass the container by reference in order to modify it in the function. What other answers haven’t addressed is that std::vector does not have a push_front member function. You can use the insert() member function on vector for O(n) insertion:

void do_something(int el, std::vector<int> &arr){
    arr.insert(arr.begin(), el);
}

Or use std::deque instead for amortised O(1) insertion:

void do_something(int el, std::deque<int> &arr){
    arr.push_front(el);
}

You can use __unused to tell the compiler that variable might not be used.

- (void)myMethod:(__unused NSObject *)theObject    
{
    // there will be no warning about `theObject`, because you wrote `__unused`

    __unused int theInt = 0;
    // there will be no warning, but you are still able to use `theInt` in the future
}

The query below returns a list of information about each field, including the MySQL field type. Here is an example:

SHOW FIELDS FROM tablename
/* returns "Field", "Type", "Null", "Key", "Default", "Extras" */

See this manual page.

You can do the following:

  public class Numbers {
    private int number1 = 50;
    private int number2 = 100;
    private List<Integer> list;

    public Numbers() {
      list = new ArrayList<Integer>();
      list.add(number1);
      list.add(number2);
    }

    int getNumber(int pos)
    {
      return list.get(pos);
    }
  }

  public class Test {
    private Numbers numbers;

    public Test(){
      numbers = new Numbers();
      int number1 = numbers.getNumber(0);
      int number2 = numbers.getNumber(1);
    }
  }

None of the solutions above worked for me because I was using Formik and I needed to mark the field "touched" along with changing the field value. Following code worked for me.

const emailField = orderPageWrapper.find('input[name="email"]')

emailField.simulate('focus')
emailField.simulate('change', { target: { value: '[email protected]', name: 'email' } })
emailField.simulate('blur')

Using the onclick attribute or applying a function to your JS onclick properties will erase your onclick initialization in <head>.

What you need to do is add click events on your button. To do that you’ll need the addEventListener or attachEvent (IE) method.

<!DOCTYPE html>
<html>
<head>
    <script>
        function addEvent(obj, event, func) {
            if (obj.addEventListener) {
                obj.addEventListener(event, func, false);
                return true;
            } else if (obj.attachEvent) {
                obj.attachEvent('on' + event, func);
            } else {
                var f = obj['on' + event];
                obj['on' + event] = typeof f === 'function' ? function() {
                    f();
                    func();
                } : func
            }
        }

        function f1()
        {
            alert("f1 called");
            //form validation that recalls the page showing with supplied inputs.    
        }
    </script>
</head>
<body>
    <form name="form1" id="form1" method="post">
        State: <select id="state ID">
        <option></option>
        <option value="ap">ap</option>
        <option value="bp">bp</option>
        </select>
    </form>

    <table><tr><td id="Save" onclick="f1()">click</td></tr></table>

    <script>
        addEvent(document.getElementById('Save'), 'click', function() {
            alert('hello');
        });
    </script>
</body>
</html>

You can use this but there remains a security issue

<script type="text/javascript">
function fnc1()
{
    var a=window.location.href;

    username="p";
    password=1234;
    window.open(a+'?username='+username+'&password='+password,"");

}   
</script>
<input type="button" onclick="fnc1()" />
<input type="text" id="atext"  />

I was getting this error until I added (as shown in the code below) $.holdReady(true) at the beginning of my web service call and $.holdReady(false) after it ends. This is jQuery thing to suspend the ready state of the page so any script within document.ready function would be waiting for this (among other possible but unknown to me things).

<span class="AjaxPlaceHolder"></span>
<script type="text/javascript">
$.holdReady(true);
function GetHTML(source, section){
    var divToBeWorkedOn = ".AjaxPlaceHolder";
    var webMethod = "../MyService.asmx/MyMethod";
    var parameters = "{'source':'" + source + "','section':'" + section + "'}";

    $.ajax({
        type: "POST",
        url: webMethod,
        data: parameters,
        contentType: "application/json; charset=utf-8",
        dataType: "json",
        async: true,
        xhrFields: {
            withCredentials: false
        },
        crossDomain: true,
        success: function(data) {
            $.holdReady(false);
            var myData = data.d;
            if (myData != null) {
                $(divToBeWorkedOn).prepend(myData.html);
            }
        },
        error: function(e){
            $.holdReady(false);
            $(divToBeWorkedOn).html("Unavailable");
        }
    });
}
GetHTML("external", "Staff Directory");
</script>

This question has been addressed, in a slightly different form, at length, here:

RESTful Authentication

But this addresses it from the server-side. Let's look at this from the client-side. Before we do that, though, there's an important prelude:

Javascript Crypto is Hopeless

Matasano's article on this is famous, but the lessons contained therein are pretty important:

https://www.nccgroup.trust/us/about-us/newsroom-and-events/blog/2011/august/javascript-cryptography-considered-harmful/

To summarize:

• A man-in-the-middle attack can trivially replace your crypto code with <script> function hash_algorithm(password){ lol_nope_send_it_to_me_instead(password); }</script>
• A man-in-the-middle attack is trivial against a page that serves any resource over a non-SSL connection.
• Once you have SSL, you're using real crypto anyways.

And to add a corollary of my own:

• A successful XSS attack can result in an attacker executing code on your client's browser, even if you're using SSL - so even if you've got every hatch battened down, your browser crypto can still fail if your attacker finds a way to execute any javascript code on someone else's browser.

This renders a lot of RESTful authentication schemes impossible or silly if you're intending to use a JavaScript client. Let's look!

HTTP Basic Auth

First and foremost, HTTP Basic Auth. The simplest of schemes: simply pass a name and password with every request.

This, of course, absolutely requires SSL, because you're passing a Base64 (reversibly) encoded name and password with every request. Anybody listening on the line could extract username and password trivially. Most of the "Basic Auth is insecure" arguments come from a place of "Basic Auth over HTTP" which is an awful idea.

The browser provides baked-in HTTP Basic Auth support, but it is ugly as sin and you probably shouldn't use it for your app. The alternative, though, is to stash username and password in JavaScript.

This is the most RESTful solution. The server requires no knowledge of state whatsoever and authenticates every individual interaction with the user. Some REST enthusiasts (mostly strawmen) insist that maintaining any sort of state is heresy and will froth at the mouth if you think of any other authentication method. There are theoretical benefits to this sort of standards-compliance - it's supported by Apache out of the box - you could store your objects as files in folders protected by .htaccess files if your heart desired!

The problem? You are caching on the client-side a username and password. This gives evil.ru a better crack at it - even the most basic of XSS vulnerabilities could result in the client beaming his username and password to an evil server. You could try to alleviate this risk by hashing and salting the password, but remember: JavaScript Crypto is Hopeless. You could alleviate this risk by leaving it up to the Browser's Basic Auth support, but.. ugly as sin, as mentioned earlier.

HTTP Digest Auth

Is Digest authentication possible with jQuery?

A more "secure" auth, this is a request/response hash challenge. Except JavaScript Crypto is Hopeless, so it only works over SSL and you still have to cache the username and password on the client side, making it more complicated than HTTP Basic Auth but no more secure.

Query Authentication with Additional Signature Parameters.

Another more "secure" auth, where you encrypt your parameters with nonce and timing data (to protect against repeat and timing attacks) and send the. One of the best examples of this is the OAuth 1.0 protocol, which is, as far as I know, a pretty stonking way to implement authentication on a REST server.

http://tools.ietf.org/html/rfc5849

Oh, but there aren't any OAuth 1.0 clients for JavaScript. Why?

JavaScript Crypto is Hopeless, remember. JavaScript can't participate in OAuth 1.0 without SSL, and you still have to store the client's username and password locally - which puts this in the same category as Digest Auth - it's more complicated than HTTP Basic Auth but it's no more secure.

Token

The user sends a username and password, and in exchange gets a token that can be used to authenticate requests.

This is marginally more secure than HTTP Basic Auth, because as soon as the username/password transaction is complete you can discard the sensitive data. It's also less RESTful, as tokens constitute "state" and make the server implementation more complicated.

SSL Still

The rub though, is that you still have to send that initial username and password to get a token. Sensitive information still touches your compromisable JavaScript.

To protect your user's credentials, you still need to keep attackers out of your JavaScript, and you still need to send a username and password over the wire. SSL Required.

Token Expiry

It's common to enforce token policies like "hey, when this token has been around too long, discard it and make the user authenticate again." or "I'm pretty sure that the only IP address allowed to use this token is XXX.XXX.XXX.XXX". Many of these policies are pretty good ideas.

Firesheeping

However, using a token Without SSL is still vulnerable to an attack called 'sidejacking': http://codebutler.github.io/firesheep/

The attacker doesn't get your user's credentials, but they can still pretend to be your user, which can be pretty bad.

tl;dr: Sending unencrypted tokens over the wire means that attackers can easily nab those tokens and pretend to be your user. FireSheep is a program that makes this very easy.

A Separate, More Secure Zone

The larger the application that you're running, the harder it is to absolutely ensure that they won't be able to inject some code that changes how you process sensitive data. Do you absolutely trust your CDN? Your advertisers? Your own code base?

Common for credit card details and less common for username and password - some implementers keep 'sensitive data entry' on a separate page from the rest of their application, a page that can be tightly controlled and locked down as best as possible, preferably one that is difficult to phish users with.

Cookie (just means Token)

It is possible (and common) to put the authentication token in a cookie. This doesn't change any of the properties of auth with the token, it's more of a convenience thing. All of the previous arguments still apply.

Session (still just means Token)

Session Auth is just Token authentication, but with a few differences that make it seem like a slightly different thing:

• Users start with an unauthenticated token.
• The backend maintains a 'state' object that is tied to a user's token.
• The token is provided in a cookie.
• The application environment abstracts the details away from you.

Aside from that, though, it's no different from Token Auth, really.

This wanders even further from a RESTful implementation - with state objects you're going further and further down the path of plain ol' RPC on a stateful server.

OAuth 2.0

OAuth 2.0 looks at the problem of "How does Software A give Software B access to User X's data without Software B having access to User X's login credentials."

The implementation is very much just a standard way for a user to get a token, and then for a third party service to go "yep, this user and this token match, and you can get some of their data from us now."

Fundamentally, though, OAuth 2.0 is just a token protocol. It exhibits the same properties as other token protocols - you still need SSL to protect those tokens - it just changes up how those tokens are generated.

There are two ways that OAuth 2.0 can help you:

• Providing Authentication/Information to Others
• Getting Authentication/Information from Others

But when it comes down to it, you're just... using tokens.

Back to your question

So, the question that you're asking is "should I store my token in a cookie and have my environment's automatic session management take care of the details, or should I store my token in Javascript and handle those details myself?"

And the answer is: do whatever makes you happy.

The thing about automatic session management, though, is that there's a lot of magic happening behind the scenes for you. Often it's nicer to be in control of those details yourself.

I am 21 so SSL is yes

The other answer is: Use https for everything or brigands will steal your users' passwords and tokens.

Overview

Synchronized keyword in Java has to do with thread-safety, that is, when multiple threads read or write the same variable.
This can happen directly (by accessing the same variable) or indirectly (by using a class that uses another class that accesses the same variable).

The synchronized keyword is used to define a block of code where multiple threads can access the same variable in a safe way.

Deeper

Syntax-wise the synchronized keyword takes an Object as it's parameter (called a lock object), which is then followed by a { block of code }.

• When execution encounters this keyword, the current thread tries to "lock/acquire/own" (take your pick) the lock object and execute the associated block of code after the lock has been acquired.

• Any writes to variables inside the synchronized code block are guaranteed to be visible to every other thread that similarly executes code inside a synchronized code block using the same lock object.

• Only one thread at a time can hold the lock, during which time all other threads trying to acquire the same lock object will wait (pause their execution). The lock will be released when execution exits the synchronized code block.

Synchronized methods:

Adding synchronized keyword to a method definition is equal to the entire method body being wrapped in a synchronized code block with the lock object being this (for instance methods) and ClassInQuestion.getClass() (for class methods).

- Instance method is a method which does not have static keyword.
- Class method is a method which has static keyword.

Technical

Without synchronization, it is not guaranteed in which order the reads and writes happen, possibly leaving the variable with garbage.
(For example a variable could end up with half of the bits written by one thread and half of the bits written by another thread, leaving the variable in a state that neither of the threads tried to write, but a combined mess of both.)

It is not enough to complete a write operation in a thread before (wall-clock time) another thread reads it, because hardware could have cached the value of the variable, and the reading thread would see the cached value instead of what was written to it.

Conclusion

Thus in Java's case, you have to follow the Java Memory Model to ensure that threading errors do not happen.
In other words: Use synchronization, atomic operations or classes that use them for you under the hoods.

In general software terms, an "artifact" is something produced by the software development process, whether it be software related documentation or an executable file.

In Maven terminology, the artifact is the resulting output of the maven build, generally a jar or war or other executable file. Artifacts in maven are identified by a coordinate system of groupId, artifactId, and version. Maven uses the groupId, artifactId, and version to identify dependencies (usually other jar files) needed to build and run your code.

This is an example of using the :checked pseudo-class to make forms more accessible. The :checked pseudo-class can be used with hidden inputs and their visible labels to build interactive widgets, such as image galleries. I created the snipped for the people that wanna test.

input[type=checkbox] + label {_x000D_
  color: #ccc;_x000D_
  font-style: italic;_x000D_
} _x000D_
input[type=checkbox]:checked + label {_x000D_
  color: #f00;_x000D_
  font-style: normal;_x000D_
} 

<input type="checkbox" id="cb_name" name="cb_name"> _x000D_
<label for="cb_name">CSS is Awesome</label> 

Another thing that can cause this error is creating a model with the centering/scaling standardize function from the arm package -- m <- standardize(lm(y ~ x, data = train))

If you then try predict(m), you get the same error as in this question.

You can still use the textmode and force the linefeed-newline with the keyword argument newline

f = open("./foo",'w',newline='\n')

Tested with Python 3.4.2.

Edit: This does not work in Python 2.7.

Try

SELECT dbo.function (parameters)

Try this code in Swift or Objective-C

Swift

self.tabBarController.selectedIndex = 1

Objective-C

[self.tabBarController setSelectedIndex:1];

If you want to automatically/periodically clean up exited containers and remove images and volumes that aren't in use by a running container you can download the Docker image meltwater/docker-cleanup.

That way you don't need to go clean it up by hand.

Just run:

docker run -d -v /var/run/docker.sock:/var/run/docker.sock:rw  -v /var/lib/docker:/var/lib/docker:rw --restart=unless-stopped meltwater/docker-cleanup:latest

It will run every 30 minutes (or however long you set it using DELAY_TIME=1800 option) and clean up exited containers and images.

More details: https://github.com/meltwater/docker-cleanup/blob/master/README.md

You can wrap the r script in a bash script and retrieve the script's path as a bash variable like so:

#!/bin/bash
     # [environment variables can be set here]
     path_to_script=$(dirname $0)

     R --slave<<EOF
        source("$path_to_script/other.R")

     EOF

=COUNTIFS(H5:H21000,">=100", H5:H21000,"<999")

Here's a solution that uses httplib instead.

import httplib

def get_status_code(host, path="/"):
    """ This function retreives the status code of a website by requesting
        HEAD data from the host. This means that it only requests the headers.
        If the host cannot be reached or something else goes wrong, it returns
        None instead.
    """
    try:
        conn = httplib.HTTPConnection(host)
        conn.request("HEAD", path)
        return conn.getresponse().status
    except StandardError:
        return None


print get_status_code("stackoverflow.com") # prints 200
print get_status_code("stackoverflow.com", "/nonexistant") # prints 404

I put all together and got easy way to convert ANSI text files to "UTF-8 No Mark":

function filesToUTF8($searchdir,$convdir,$filetypes) {
  $get_files = glob($searchdir.'*{'.$filetypes.'}', GLOB_BRACE);
  foreach($get_files as $file) {
    $expl_path = explode('/',$file);
    $filename = end($expl_path);
    $get_file_content = file_get_contents($file);
    $new_file_content = iconv(mb_detect_encoding($get_file_content, mb_detect_order(), true), "UTF-8", $get_file_content);
    $put_new_file = file_put_contents($convdir.$filename,$new_file_content);
  }
}

Usage: filesToUTF8('C:/Temp/','C:/Temp/conv_files/','php,txt');

As suggested above the inclusion of

/usr/lib/openmpi/include 

in the include path takes care of this (in my case)

I suggest you use curses.h or ncurses.h these implement keyboard management routines including getch(). You have several options to change the behavior of getch (i.e. wait for keypress or not).

This worked for me like charm. I went through multiple ways but then this helped me. Make sure you follow each step and name the XML files exactly same.

The process is a little tedious but yes it does work.

You can sort a list in-place just by calling List<T>.Sort:

list.Sort();

That will use the natural ordering of elements, which is fine in your case.

EDIT: Note that in your code, you'd need

_details.Sort();

as the Sort method is only defined in List<T>, not IList<T>. If you need to sort it from the outside where you don't have access to it as a List<T> (you shouldn't cast it as the List<T> part is an implementation detail) you'll need to do a bit more work.

I don't know of any IList<T>-based in-place sorts in .NET, which is slightly odd now I come to think of it. IList<T> provides everything you'd need, so it could be written as an extension method. There are lots of quicksort implementations around if you want to use one of those.

If you don't care about a bit of inefficiency, you could always use:

public void Sort<T>(IList<T> list)
{
    List<T> tmp = new List<T>(list);
    tmp.Sort();
    for (int i = 0; i < tmp.Count; i++)
    {
        list[i] = tmp[i];
    }
}

In other words, copy, sort in place, then copy the sorted list back.

You can use LINQ to create a new list which contains the original values but sorted:

var sortedList = list.OrderBy(x => x).ToList();

It depends which behaviour you want. Note that your shuffle method isn't really ideal:

• Creating a new Random within the method runs into some of the problems shown here
• You can declare val inside the loop - you're not using that default value
• It's more idiomatic to use the Count property when you know you're working with an IList<T>
• To my mind, a for loop is simpler to understand than traversing the list backwards with a while loop

There are other implementations of shuffling with Fisher-Yates on Stack Overflow - search and you'll find one pretty quickly.

And here's how to do it in Swift:

 func registerForKeyboardNotifications() {
    NSNotificationCenter.defaultCenter().addObserver(
        self,
        selector: "keyboardWasShown:",
        name: UIKeyboardDidShowNotification,
        object: nil)

    NSNotificationCenter.defaultCenter().addObserver(
        self,
        selector: "keyboardWillBeHidden:",
        name: UIKeyboardWillHideNotification,
        object: nil)
}

func keyboardWasShown(notification: NSNotification) {
    println("Keyboard was shown");
}

func keyboardWillBeHidden(notification: NSNotification) {
    println("Keyboard was dismissed");
}

Don't forget to unregister:

 override func viewWillDisappear(animated: Bool) {
    NSNotificationCenter.defaultCenter().removeObserver(self,
        name: UIKeyboardDidShowNotification,
        object: nil)

    NSNotificationCenter.defaultCenter().removeObserver(self,
        name: UIKeyboardWillHideNotification,
        object: nil)
}

And if you want to dismiss keyboard on pressing the "Return" button:

class ViewController: UIViewController, UITextFieldDelegate {

@IBOutlet weak var yourTextField: UITextField!

override func viewDidLoad() {
    super.viewDidLoad()
    registerForKeyboardNotifications()
    yourTextField.delegate = self
}

func textFieldShouldReturn(textField: UITextField!) -> Bool {
    self.view.endEditing(true);
    return false;
}

}

There seems to be a problem with some versions of R and libcurl. I have had the same problem on Mac (R version 3.2.2) and Ubuntu (R version 3.0.2) and in both instances it was resolved simply by running this before the install.packages command

options(download.file.method = "wget")

The solution was suggested by a friend, however, I haven't been able to find it in any of the forums, hence submitting this answer for others.

put this line in parent construct : $this->load->database();

function  __construct() {
    parent::__construct();
    $this->load->library('lib_name');
    $model=array('model_name');
    $this->load->model($model);
    $this->load->database();
}

this way.. it should work..

use swift this code

view.translatesAutoresizingMaskIntoConstraints = false

JPA is just a specification which needs concrete implementation. The default implementation oracle provide is "Eclipselink" now. (Toplink is donated by Oracle to Eclipse foundation to merge with eclipselink)

(Reference : http://www.oracle.com/technetwork/middleware/toplink/index-085257.html http://www.eclipse.org/org/press-release/20080317_Eclipselink.php )

Using Eclipselink, one can be sure that the code is portable to any implementation if need arises. Hibernate is also a full JPA implementation + MORE ( Sort of JPA Plus). Hibernate is super set of JPA with some extra Hibernate specific functionality. So app developed in Hibernate may not be compatible when switched to other implementation. Still hibernate is choice of majority of developers as JPA implementation and widely used.

Another JPA implementation is OpenJPA (openjpa.apache.org) which is an extension of Kodo implementation.

Have you tried the uncurl package (https://github.com/spulec/uncurl)? You can install it via pip, pip install uncurl. Your curl request returns:

>>> uncurl "curl --header \"Authorization:access_token myToken\" https://website.com/id"

requests.get("https://website.com/id",
    headers={
        "Authorization": "access_token myToken"
    },
    cookies={},
)

If you're using less , and it's not loading the icons font you must check out the font path go to the file variable.less and change the @icon-font-path path , that worked for me.

This will return the rows that have at least ONE non-NA value.

final[rowSums(is.na(final))<length(final),]

This will return the rows that have at least TWO non-NA value.

final[rowSums(is.na(final))<(length(final)-1),]

This worked for me, it works in firefox, ie and chrome.

    var content = "This is a test Message";

    var contentHtml = [
        '<div><b>',
        'TestReport',
        '<button style="float:right; margin-right:10px;"',
        'id="printButton" onclick="printDocument()">Print</button></div>',
        content
    ].join('');

    var printWindow = window.open();

    printWindow.document.write('<!DOCTYPE HTML><html><head<title>Reports</title>',
        '<script>function printDocument() {',
        'window.focus();',
        'window.print();',
        'window.close();',
        '}',
        '</script>');

    printWindow.document.write("stylesheet link here");

    printWindow.document.write('</head><body>');
    printWindow.document.write(contentHtml);
    printWindow.document.write('</body>');
    printWindow.document.write('</html>');
    printWindow.document.close();

Desired capabilities comes in handy while doing remote or parallel execution using selenium grid. We will be parametrizing the browser details and passing in to selenium server using desired capabilities class.

Another usage is, test automation using Appium as shown below

// Created object of DesiredCapabilities class. 
DesiredCapabilities capabilities = new DesiredCapabilities(); 
// Set android deviceName desired capability. Set your device name. 
capabilities.setCapability("deviceName", "your Device Name"); 
// Set BROWSER_NAME desired capability. 
capabilities.setCapability(CapabilityType.BROWSER_NAME, "Chrome"); 
// Set android VERSION desired capability. Set your mobile device's OS version. 
capabilities.setCapability(CapabilityType.VERSION, "5.1"); 
// Set android platformName desired capability. It's Android in our case here. 
capabilities.setCapability("platformName", "Android");

Based on stdOrgnlDave answer I have defined this wrapper that it can be called with optional kinds so the encoder will work only for certain kinds inside your projects. I believe the work should be done inside your code and not to use this "default" encoder since "it is better explicit than implicit", but I understand using this will save some of your time. :-)

import time
import json
import decimal
from uuid import UUID
from datetime import datetime

def JSONEncoder_newdefault(kind=['uuid', 'datetime', 'time', 'decimal']):
    '''
    JSON Encoder newdfeault is a wrapper capable of encoding several kinds
    Use it anywhere on your code to make the full system to work with this defaults:
        JSONEncoder_newdefault()  # for everything
        JSONEncoder_newdefault(['decimal'])  # only for Decimal
    '''
    JSONEncoder_olddefault = json.JSONEncoder.default

    def JSONEncoder_wrapped(self, o):
        '''
        json.JSONEncoder.default = JSONEncoder_newdefault
        '''
        if ('uuid' in kind) and isinstance(o, uuid.UUID):
            return str(o)
        if ('datetime' in kind) and isinstance(o, datetime):
            return str(o)
        if ('time' in kind) and isinstance(o, time.struct_time):
            return datetime.fromtimestamp(time.mktime(o))
        if ('decimal' in kind) and isinstance(o, decimal.Decimal):
            return str(o)
        return JSONEncoder_olddefault(self, o)
    json.JSONEncoder.default = JSONEncoder_wrapped

# Example
if __name__ == '__main__':
    JSONEncoder_newdefault()

Coming from the embedded world, where even uclibc is not always available, and code like

uint64_t myval = 0xdeadfacedeadbeef; printf("%llx", myval);

is printing you crap or not working at all -- i always use a tiny helper, that allows me to dump properly uint64_t hex:

#include <stdlib.h>
#include <stdio.h>
#include <stdint.h>

char* ullx(uint64_t val)
{
    static char buf[34] = { [0 ... 33] = 0 };
    char* out = &buf[33];
    uint64_t hval = val;
    unsigned int hbase = 16;

    do {
        *out = "0123456789abcdef"[hval % hbase];
        --out;
        hval /= hbase;
    } while(hval);

    *out-- = 'x', *out = '0';

    return out;
}

You can use

from torchsummary import summary

You can specify device

device = torch.device("cuda" if torch.cuda.is_available() else "cpu")

You can create a Network, and if you are using MNIST datasets, then following commands will work and show you summary

model = Network().to(device)
summary(model,(1,28,28))

(?<=\[).+?(?=\])

Will capture content without brackets

• (?<=\[) - positive lookbehind for [

• .*? - non greedy match for the content

• (?=\]) - positive lookahead for ]

EDIT: for nested brackets the below regex should work:

(\[(?:\[??[^\[]*?\]))

This worked for me in my application:

def get_celery_queue_active_jobs(queue_name):
    connection = <CELERY_APP_INSTANCE>.connection()

    try:
        channel = connection.channel()
        name, jobs, consumers = channel.queue_declare(queue=queue_name, passive=True)
        active_jobs = []

        def dump_message(message):
            active_jobs.append(message.properties['application_headers']['task'])

        channel.basic_consume(queue=queue_name, callback=dump_message)

        for job in range(jobs):
            connection.drain_events()

        return active_jobs
    finally:
        connection.close()

active_jobs will be a list of strings that correspond to tasks in the queue.

Don't forget to swap out CELERY_APP_INSTANCE with your own.

Thanks to @ashish for pointing me in the right direction with his answer here: https://stackoverflow.com/a/19465670/9843399

You can just create an object like this:

public class SomeQuery
{
    public string SomeParameter { get; set; }
    public int? SomeParameter2 { get; set; }
}

And then in controller just make something like that:

[HttpGet]
public IActionResult FindSomething([FromQuery] SomeQuery query)
{
    // Your implementation goes here..
}

Even better, you can create API model from:

[HttpGet]
public IActionResult GetSomething([FromRoute] int someId, [FromQuery] SomeQuery query)

to:

[HttpGet]
public IActionResult GetSomething(ApiModel model)

public class ApiModel
{
    [FromRoute]
    public int SomeId { get; set; }
    [FromQuery]
    public string SomeParameter { get; set; }
    [FromQuery]
    public int? SomeParameter2 { get; set; }
}

Go to your Models and check, because you might have truncated a number of words for that particular column eg. max_length="150".

For to use looping to get all arguments and in pure batch:

Obs: For using without: ?*&<>

@echo off && setlocal EnableDelayedExpansion

for %%Z in (%*)do set "_arg_=%%Z" && set/a "_cnt+=1+0" && call set "_arg_[!_cnt!]=!_arg_!")

:: write/test these arguments/parameters ::
for /l %%l in (1 1 !_cnt!)do echo/ The argument n:%%l is: !_arg_[%%l]!

goto :eof 

Your code is ready to do something with the argument number where it needs, like...

@echo off && setlocal EnableDelayedExpansion

for %%Z in (%*)do set "_arg_=%%Z" && set/a "_cnt+=1+0" && call set "_arg_[!_cnt!]=!_arg_!"

echo= !_arg_[1]! !_arg_[2]! !_arg_[2]!> log.txt

I'm a little late on the party, but its actualy possible to emulate borders using a box-shadow

.border {_x000D_
  background-color: #ededed;_x000D_
  padding: 10px;_x000D_
  margin-bottom: 5px;_x000D_
}_x000D_
_x000D_
.border-top {_x000D_
  box-shadow: inset 0 3px 0 0 cornflowerblue;_x000D_
}_x000D_
_x000D_
.border-right {_x000D_
  box-shadow: inset -3px 0 0 cornflowerblue;_x000D_
}_x000D_
_x000D_
.border-bottom {_x000D_
  box-shadow: inset 0 -3px 0 0 cornflowerblue;_x000D_
}_x000D_
_x000D_
.border-left {_x000D_
  box-shadow: inset 3px 0 0 cornflowerblue;_x000D_
}

<div class="border border-top">border-top</div>_x000D_
<div class="border border-right">border-right</div>_x000D_
<div class="border border-bottom">border-bottom</div>_x000D_
<div class="border border-left">border-left</div>

EDIT: I understood this question wrong, but I will leave the awnser as more people might misunderstand the question and came for the awnser I supplied.

The security's authorization check part gets the authenticated object from SecurityContext, which will be set when a request gets through the spring security filter. My assumption here is that soon after the login this is not being set. You probably can use a hack as given below to set the value.

try {
    SecurityContext ctx = SecurityContextHolder.createEmptyContext();
    SecurityContextHolder.setContext(ctx);
    ctx.setAuthentication(event.getAuthentication());

    //Do what ever you want to do

} finally {
    SecurityContextHolder.clearContext();
}

Update:

Also you can have a look at the InteractiveAuthenticationSuccessEvent which will be called once the SecurityContext is set.

$(function() {
        $("#select-image").selectable({
            selected: function( event, ui ) { 
                var $variable = $('.ui-selected').html(); 
                console.log($variable);
            }
        });
    });

or

$(function() {
        $("#select-image").selectable({
            selected: function( event, ui ) { 
                var $variable = $('.ui-selected').text(); 
                console.log($variable);
            }
        });
    });

or

$(function() {
        $("#select-image").selectable({
            selected: function( event, ui ) { 
                var $variable = $('.ui-selected').val(); 
                console.log($variable);
            }
        });
    });

you could use ts-node-dev

It restarts target node process when any of required files changes (as standard node-dev) but shares Typescript compilation process between restarts.

Install

yarn add ts-node-dev --dev

and your package.json could be like this

"scripts": {
  "test": "echo \"Error: no test specified\" && exit 1",
  "tsc": "tsc",
  "dev": "ts-node-dev --respawn --transpileOnly ./src/index.ts",
  "prod": "tsc && node ./build/index.js"
}

You could use Qt which, in case you don't know, is C++ with a bunch of additional libraries and classes and whatnot. Qt has a very convenient QByteArray class which I'm quite sure would suit your needs.

http://qt-project.org/

As you don't only want to look for a number but also extract it, you should write a small function doing that for you. Go letter by letter till you spot a digit. Ah, just found the necessary code for you on stackoverflow: find integer in string. Look at the accepted answer.

May 2017; I had the same issue, could not even get to apps as it just cycled between starting and stopping. Went into avd settings, edited the multi core (unticked the box) and set graphics to software Gles. It appears to have fixed the issue

As a rule of thumb, when I receive this error in Python I compare the function signature with the function execution.

For example:

def print_files(file_list, parent_id):
    for file in file_list:
        print(title: %s, id: %s' % (file['title'], file['id']

So if I'll call this function with parameters placed in the wrong order and pass the list as the 2nd argument and a string as the 1st argument:

print_files(parent_id, list_of_files) # <----- Accidentally switching arguments location

The function will try to iterate over the parent_id string instead of file_list and it will expect to see the index as an integer pointing to the specific character in string and not an index which is a string (title or id).

This will lead to the TypeError: string indices must be integers error.

Due to its dynamic nature (as opposed to languages like Java, C# or Typescript), Python will not inform you about this syntax error.

I just solve this error while using capybara in ror project by adding:

Capybara.ignore_elements = true

to features/support/env.rb.

On ipython or jupyter notebook, you can use all the above mentioned ways, but i go with

my_func?

or

?my_func

for quick summary of both method signature and docstring.

I avoid using

my_func??

(as commented by @rohan) for docstring and use it only to check the source code

You are always checking for a true condition, hence your message will always show.

You should replace your if (true) statement with if ( n == JOptionPane.YES_OPTION)

When one of the showXxxDialog methods returns an integer, the possible values are:

YES_OPTION NO_OPTION CANCEL_OPTION OK_OPTION CLOSED_OPTION

I don't think this can be done using jQuery's animate function because the background image does not have the necessary CSS properties to do such fading. jQuery can only utilize what the browser makes possible. (jQuery experts, correct me if I'm wrong of course.)

I guess you would have to work around this by not using genuine background-images, but div elements containing the image, positioned using position: absolute (or fixed) and z-index for stacking. You would then animate those divs.

I did this and it works for me. "content" is placesContent object. not the html content!

var placesContent = $('#placescontent');
$('#places').popover({
        trigger: "click",
        placement: "bottom",
        container: 'body',
        html : true,
        content : placesContent,
    });

$('#places').on('shown.bs.popover', function(){
  $('#addPlaceBtn').on('click', addPlace);
}

<div id="placescontent"><div id="addPlaceBtn">Add</div></div>

The instanceof operator does not need explicit null checks, as it does not throw a NullPointerException if the operand is null.

At run time, the result of the instanceof operator is true if the value of the relational expression is not null and the reference could be cast to the reference type without raising a class cast exception.

If the operand is null, the instanceof operator returns false and hence, explicit null checks are not required.

Consider the below example,

public static void main(String[] args) {
         if(lista != null && lista instanceof ArrayList) {                     //Violation
                System.out.println("In if block");
         }
         else {
                System.out.println("In else block");
         }
}

The correct usage of instanceof is as shown below,

public static void main(String[] args) {
      
         if(lista instanceof ArrayList){                     //Correct way
                  System.out.println("In if block");
         }
            else {
                 System.out.println("In else block");
         }  
}

The Web Security team at Mozilla put together a great guide, which we abide by in the development of our sites and services.

as per the Chart js documentation page tick configuration section. you can format the value of each tick using the callback function. for example I wanted to change locale of displayed dates to be always German. in the ticks parts of the axis options

ticks: {
    callback: function(value) { 
        return new Date(value).toLocaleDateString('de-DE', {month:'short', year:'numeric'}); 
    },
},

This is how I achieved the same in Scala. I am not sure if it is more efficient than the valid answer, but it requires less coding

val parquetFileDF = sqlContext.read.parquet("myParquetFule.parquet")

val myRow7th = parquetFileDF.rdd.take(7).last

Can't you originally get the data as a JSONObject?

Perhaps parse the string as both a JSONObject and a JSONArray in the first place? Where is the JSON string coming from?

I'm not sure that it is possible to convert a JsonArray into a JsonObject.

I presume you are using the following from json.org

• JSONObject.java
  A JSONObject is an unordered collection of name/value pairs. Its external form is a string wrapped in curly braces with colons between the names and values, and commas between the values and names. The internal form is an object having get() and opt() methods for accessing the values by name, and put() methods for adding or replacing values by name. The values can be any of these types: Boolean, JSONArray, JSONObject, Number, and String, or the JSONObject.NULL object.

• JSONArray.java
  A JSONArray is an ordered sequence of values. Its external form is a string wrapped in square brackets with commas between the values. The internal form is an object having get() and opt() methods for accessing the values by index, and put() methods for adding or replacing values. The values can be any of these types: Boolean, JSONArray, JSONObject, Number, and String, or the JSONObject.NULL object.

include.prepload.js file will have a line something like below. probably as the last line.

//# sourceMappingURL=include.prepload.js.map

Delete it and the error will go away.

Appart from

plt.xticks(rotation=90)

this is also possible:

plt.xticks(rotation='vertical')

Assuming you're passing in strings rather than integers, try casting the arguments to integers:

def example(arg1, arg2, arg3):
     if int(arg1) == 1 and int(arg2) == 2 and int(arg3) == 3:
          print("Example Text")

(Edited to emphasize I'm not asking for clarification; I was trying to be diplomatic in my answer. )

When your getting this error "ORA-12505, TNS:listener does not currently know of SID given in connect descriptor"

There is also configuration option: query_cache_size=0

To disable the query cache at server startup, set the query_cache_size system variable to 0. By disabling the query cache code, there is no noticeable overhead. If you build MySQL from source, query cache capabilities can be excluded from the server entirely by invoking configure with the --without-query-cache option.

Try this:

that should do it.

Try Jochen Kalmbach's Memory Leak Detector on Code Project. The URL to the latest version was somewhere in the comments when I last checked.

There are many good answers here but you should avoid at all cost to pass untrusted variables to subprocess using shell=True as this is a security risk. The variables can escape to the shell and run arbitrary commands! If you just can't avoid it at least use python3's shlex.quote() to escape the string (if you have multiple space-separated arguments, quote each split instead of the full string).

shell=False is always the default where you pass an argument array.

Now the safe solutions...

Method #1

Change your own process's environment - the new environment will apply to python itself and all subprocesses.

os.environ['LD_LIBRARY_PATH'] = 'my_path'
command = ['sqsub', '-np', var1, '/homedir/anotherdir/executable']
subprocess.check_call(command)

Method #2

Make a copy of the environment and pass is to the childen. You have total control over the children environment and won't affect python's own environment.

myenv = os.environ.copy()
myenv['LD_LIBRARY_PATH'] = 'my_path'
command = ['sqsub', '-np', var1, '/homedir/anotherdir/executable']
subprocess.check_call(command, env=myenv)

Method #3

Unix only: Execute env to set the environment variable. More cumbersome if you have many variables to modify and not portabe, but like #2 you retain full control over python and children environments.

command = ['env', 'LD_LIBRARY_PATH=my_path', 'sqsub', '-np', var1, '/homedir/anotherdir/executable']
subprocess.check_call(command)

Of course if var1 contain multiple space-separated argument they will now be passed as a single argument with spaces. To retain original behavior with shell=True you must compose a command array that contain the splitted string:

command = ['sqsub', '-np'] + var1.split() + ['/homedir/anotherdir/executable']

@BozidarS: FileAPI is supported quite well nowadays and provides a number of useful options.

var file = document.forms['formName']['inputName'].files[0];
//file.name == "photo.png"
//file.type == "image/png"
//file.size == 300821

I have had good success using Spring WS for the client end of a web service app - see http://static.springsource.org/spring-ws/sites/1.5/reference/html/client.html

My project uses a combination of:

• XMLBeans (generated from a simple Maven job using the xmlbeans-maven-plugin)

• Spring WS - using marshalSendAndReceive() reduces the code down to one line for sending and receiving

• some Dozer - mapping the complex XMLBeans to simple beans for the client GUI

This means that you must declare strict mode by writing "use strict" at the beginning of the file or the function to use block-scope declarations.

EX:

function test(){
    "use strict";
    let a = 1;
} 

If we don't think this is a bug the team should fix, at lease MSDN should improve the document. The confusing really comes from the poor document of this. In MSDN, it explains the parameters name as,

Type: System.String
The name of the form field to return.

This just means the final html it generates will use that parameter as the name of the select input. But, it actually means more than that.

I guess the designer assumes that user will use a view model to display the dropdownlist, also will use post back to the same view model. But in a lot cases, we don't really follow that assumption.

Use the example above,

public class Person {
    public int Id { get; set; }
    public string Name { get; set; }
}

If we follow the assumption,we should define a view model for this dropdownlist related view

public class PersonsSelectViewModel{
    public string SelectedPersonId,
    public List<SelectListItem> Persons;
}

Because when post back, only the selected value will post back, so it assume it should post back to the model's property SelectedPersonId, which means Html.DropDownList's first parameter name should be 'SelectedPersonId'. So, the designer thinks that when display the model view in the view, the model's property SelectedPersonId should hold the default value of that dropdown list. Even thought your List<SelectListItem> Persons already set the Selected flag to indicate which one is selected/default, the tml.DropDownList will actually ignore that and rebuild it's own IEnumerable<SelectListItem> and set the default/selected item based on the name.

Here is the code from asp.net mvc

private static MvcHtmlString SelectInternal(this HtmlHelper htmlHelper, ModelMetadata metadata,
            string optionLabel, string name, IEnumerable<SelectListItem> selectList, bool allowMultiple,
            IDictionary<string, object> htmlAttributes)
{
    ...

    bool usedViewData = false;

    // If we got a null selectList, try to use ViewData to get the list of items.
    if (selectList == null)
    {
        selectList = htmlHelper.GetSelectData(name);
        usedViewData = true;
    }

    object defaultValue = (allowMultiple) ? htmlHelper.GetModelStateValue(fullName, typeof(string[])) : htmlHelper.GetModelStateValue(fullName, typeof(string));

    // If we haven't already used ViewData to get the entire list of items then we need to
    // use the ViewData-supplied value before using the parameter-supplied value.
    if (defaultValue == null && !String.IsNullOrEmpty(name))
    {
        if (!usedViewData)
        {
            defaultValue = htmlHelper.ViewData.Eval(name);
        }
        else if (metadata != null)
        {
            defaultValue = metadata.Model;
        }
    }

    if (defaultValue != null)
    {
        selectList = GetSelectListWithDefaultValue(selectList, defaultValue, allowMultiple);
    }

    ...

    return tagBuilder.ToMvcHtmlString(TagRenderMode.Normal);
}

So, the code actually went further, it not only try to look up the name in the model, but also in the viewdata, as soon as it finds one, it will rebuild the selectList and ignore your original Selected.

The problem is, in a lot of cases, we don't really use it that way. we just want to throw in a selectList with one/multiple item(s) Selected set true.

Of course the solution is simple, use a name that not in the model nor in the viewdata. When it can not find a match, it will use the original selectList and the original Selected will take affect.

But i still think mvc should improve it by add one more condition

if ((defaultValue != null) && (!selectList.Any(i=>i.Selected)))
{
    selectList = GetSelectListWithDefaultValue(selectList, defaultValue, allowMultiple);
}

Because, if the original selectList has already had one Selected, why would you ignore that?

Just my thoughts.

I would not suggest to use sll or srl with std_logic_vector.

During simulation sll gave me 'U' value for those bits, where I expected 0's.

Use shift_left(), shift_right() functions.

For example:

OP1 : in std_logic_vector(7 downto 0); signal accum: std_logic_vector(7 downto 0);

accum <= std_logic_vector(shift_left(unsigned(accum), to_integer(unsigned(OP1)))); accum <= std_logic_vector(shift_right(unsigned(accum), to_integer(unsigned(OP1))));

You should first check the app version on the market and compare it with the version of the app on the device. If they are different, it may be an update available. In this post I wrote down the code for getting the current version of market and current version on the device and compare them together. I also showed how to show the update dialog and redirect the user to the update page. Please visit this link: https://stackoverflow.com/a/33925032/5475941

Well, your code is not reproducible so we will never know for sure, but this is what help('break')says:

break breaks out of a for, while or repeat loop; control is transferred to the first statement outside the inner-most loop.

So yes, break only breaks the current loop. You can also see it in action with e.g.:

for (i in 1:10)
{
    for (j in 1:10)
    {
        for (k in 1:10)
        {
            cat(i," ",j," ",k,"\n")
            if (k ==5) break
        }   
    }
}

I in no way want to compete with Mark's answer, but just wanted to highlight the piece that finally made everything click as someone new to Javascript inheritance and its prototype chain.

Only property reads search the prototype chain, not writes. So when you set

myObject.prop = '123';

It doesn't look up the chain, but when you set

myObject.myThing.prop = '123';

there's a subtle read going on within that write operation that tries to look up myThing before writing to its prop. So that's why writing to object.properties from the child gets at the parent's objects.

Try:

SELECT * FROM information_schema.statistics 
  WHERE table_schema = [DATABASE NAME] 
    AND table_name = [TABLE NAME] AND column_name = [COLUMN NAME]

It will tell you if there is an index of any kind on a certain column without the need to know the name given to the index. It will also work in a stored procedure (as opposed to show index)

Set

display: block;

on a and give some height

This simple method should do the job:

import re

def convert(name):
    return re.sub(r'([A-Z]*)([A-Z][a-z]+)', lambda x: (x.group(1) + '_' if x.group(1) else '') + x.group(2) + '_', name).rstrip('_').lower()

• We look for capital letters that are precedeed by any number of (or zero) capital letters, and followed by any number of lowercase characters.
• An underscore is placed just before the occurence of the last capital letter found in the group, and one can be placed before that capital letter in case it is preceded by other capital letters.
• If there are trailing underscores, remove those.
• Finally, the whole result string is changed to lower case.

(taken from here, see working example online)

What I did to get around this was to create a base class for all my activities where I store global data. In the first activity, I saved the context in a variable in my base class like so:

Base Class

public static Context myucontext; 

First Activity derived from the Base Class

mycontext = this

Then I use mycontext instead of getApplicationContext when creating dialogs.

AlertDialog alertDialog = new AlertDialog.Builder(mycontext).create();

If you are trying to do something fast, efficient and readable, use a standard if...then...else structure like this:

var d = this.dealer;
if (d < 12) {
    if (d < 5) {
        alert("less than five");
    }else if (d < 9) {
        alert("between 5 and 8");
    }else{
        alert("between 9 and 11");
    }
}else{
    alert("none");
}

If you want to obfuscate it and make it awful (but small), try this:

var d=this.dealer;d<12?(d<5?alert("less than five"):d<9?alert("between 5 and 8"):alert("between 9 and 11")):alert("none");

BTW, the above code is a JavaScript if...then...else shorthand statement. It is a great example of how NOT to write code unless obfuscation or code minification is the goal. Be aware that code maintenance can be an issue if written this way. Very few people can easily read through it, if at all. The code size, however, is 50% smaller than the standard if...then...else without any loss of performance. This means that in larger codebases, minification like this can greatly speed code delivery across bandwidth constrained or high latency networks.

This, however, should not be considered a good answer. It is just an example of what CAN be done, not what SHOULD be done.

EDIT: as of Java8 you'd better use Files class:

Path resultingPath = Files.createDirectories('A/B');

I don't know if this ultimately fixes your problem but class File has method mkdirs() which fully creates the path specified by the file.

File f = new File("/A/B/");
f.mkdirs();

ALTER SCHEMA TargetSchema 
    TRANSFER SourceSchema.TableName;

If you want to move all tables into a new schema, you can use the undocumented (and to be deprecated at some point, but unlikely!) sp_MSforeachtable stored procedure:

I think you need to explicitly pass the data attribute. One way to do this is to use the data = $('#your-form-id').serialize();

This post may be helpful. Post with jquery and ajax

Have a look at the doc here.. Ajax serialize

If your class is non-activity class, and creating an instance of it from the activiy, you can pass an instance of context via constructor of the later as follows:

class YourNonActivityClass{

// variable to hold context
private Context context;

//save the context recievied via constructor in a local variable

public YourNonActivityClass(Context context){
    this.context=context;
}

}

You can create instance of this class from the activity as follows:

new YourNonActivityClass(this);

For readability, I prefer this:

if (inputString.length() > maxLength) {
    inputString = inputString.substring(0, maxLength);
}

over the accepted answer.

int maxLength = (inputString.length() < MAX_CHAR)?inputString.length():MAX_CHAR;
inputString = inputString.substring(0, maxLength);

There is a calc function in both SCSS [compile-time] and CSS [run-time]. You're likely invoking the former instead of the latter.

For obvious reasons mixing units won't work compile-time, but will at run-time.

You can force the latter by using unquote, a SCSS function.

.selector { height: unquote("-webkit-calc(100% - 40px)"); }

See some of the answers to my similar question why-cant-i-push-from-a-shallow-clone and the link to the recent thread on the git list.

Ultimately, the 'depth' measurement isn't consistent between repos, because they measure from their individual HEADs, rather than (a) your Head, or (b) the commit(s) you cloned/fetched, or (c) something else you had in mind.

The hard bit is getting one's Use Case right (i.e. self-consistent), so that distributed, and therefore probably divergent repos will still work happily together.

It does look like the checkout --orphan is the right 'set-up' stage, but still lacks clean (i.e. a simple understandable one line command) guidance on the "clone" step. Rather it looks like you have to init a repo, set up a remote tracking branch (you do want the one branch only?), and then fetch that single branch, which feels long winded with more opportunity for mistakes.

Edit: For the 'clone' step see this answer

It wasn't specified in the original question (although I saw OP post in comments that this wasn't an option), but many developers on macOS have the Homebrew package manager installed.

For future developers who stumble upon this question, as long as the assumption (or requirement) of Homebrew being installed exists (e.g., in an engineering organization in a company), nproc is one of the common GNU binaries that is included in the coreutils package.

brew install coreutils

If you have scripts that you would prefer to write once (for Linux + macOS) instead of twice, or to avoid having if blocks where you need to detect the OS to know whether or not to call nproc vs sysctl -n hw.logicalcpu, this may be a better option.

Supposing the list may be long and the numbers may repeat, consider using the SortedList type from the Python sortedcontainers module. The SortedList type will automatically maintain the tuples in order by number and allow for fast searching.

For example:

from sortedcontainers import SortedList
sl = SortedList([(1,"juca"),(22,"james"),(53,"xuxa"),(44,"delicia")])

# Get the index of 53:

index = sl.bisect((53,))

# With the index, get the tuple:

tup = sl[index]

This will work a lot faster than the list comprehension suggestion by doing a binary search. The dictionary suggestion will be faster still but won't work if there could be duplicate numbers with different strings.

If there are duplicate numbers with different strings then you need to take one more step:

end = sl.bisect((53 + 1,))

results = sl[index:end]

By bisecting for 54, we will find the end index for our slice. This will be significantly faster on long lists as compared with the accepted answer.

Using Objective-C

You should register a UIApplicationWillEnterForegroundNotification in your ViewController's viewDidLoad method and whenever app comes back from background you can do whatever you want to do in the method registered for notification. ViewController's viewWillAppear or viewDidAppear won't be called when app comes back from background to foreground.

-(void)viewDidLoad{

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(doYourStuff)

  name:UIApplicationWillEnterForegroundNotification object:nil];
}

-(void)doYourStuff{

   // do whatever you want to do when app comes back from background.
}

Don't forget to unregister the notification you are registered for.

-(void)dealloc {
    [[NSNotificationCenter defaultCenter] removeObserver:self];
}

Note if you register your viewController for UIApplicationDidBecomeActiveNotification then your method would be called every time your app becomes active, It is not recommended to register viewController for this notification .

Using Swift

For adding observer you can use the following code

 override func viewDidLoad() {
    super.viewDidLoad()

     NotificationCenter.default.addObserver(self, selector: "doYourStuff", name: UIApplication.willEnterForegroundNotification, object: nil)
 }

 func doYourStuff(){
     // your code
 }

To remove observer you can use deinit function of swift.

deinit {
    NotificationCenter.default.removeObserver(self)
}

strchr for searching a char from start (strrchr from the end):

  char str[] = "This is a sample string";

  if (strchr(str, 'h') != NULL) {
      /* h is in str */
  }

You can also solve it by jQuery:

var new_width = $('#container').width();
$('#fixed').width(new_width); 

This was so helpful to me because my layout was responsive, and the inherit solution wasn't working with me!
