Hope you dont mind Xml.Linq and .net3.5+

XElement ele = XElement.Load("text.xml");
String aXmlString = ele.toString(SaveOptions.DisableFormatting);

Depending on what you are interested in, you can probably skip the whole 'string' var part and just use XLinq objects

Just like you do for getting something from the CNode you also need to do for the ANode

XmlNodeList xnList = xml.SelectNodes("/Element[@*]");
foreach (XmlNode xn in xnList)
{
  XmlNode anode = xn.SelectSingleNode("ANode");
    if (anode!= null)
    {
        string id = anode["ID"].InnerText;
        string date = anode["Date"].InnerText;
        XmlNodeList CNodes = xn.SelectNodes("ANode/BNode/CNode");
        foreach (XmlNode node in CNodes)
        {
         XmlNode example = node.SelectSingleNode("Example");
         if (example != null)
         {
            string na = example["Name"].InnerText;
            string no = example["NO"].InnerText;
         }
        }
    }
}

Also, note that XDocument is supported in Xbox 360 and Windows Phone OS 7.0. If you target them, develop for XDocument or migrate from XmlDocument.

Assuming doc is your instance of org.w3c.dom.Document:

TransformerFactory tf = TransformerFactory.newInstance();
Transformer transformer = tf.newTransformer();
transformer.setOutputProperty(OutputKeys.OMIT_XML_DECLARATION, "yes");
StringWriter writer = new StringWriter();
transformer.transform(new DOMSource(doc), new StreamResult(writer));
String output = writer.getBuffer().toString().replaceAll("\n|\r", "");

There aren't any quotes. It's just VS debugger. Try printing to the console or saving to a file and you'll see. As a side note: always dispose disposable objects:

using (var stringWriter = new StringWriter())
using (var xmlTextWriter = XmlWriter.Create(stringWriter))
{
    xmlDoc.WriteTo(xmlTextWriter);
    xmlTextWriter.Flush();
    return stringWriter.GetStringBuilder().ToString();
}

You need to do something like this:

// instantiate XmlDocument and load XML from file
XmlDocument doc = new XmlDocument();
doc.Load(@"D:\test.xml");

// get a list of nodes - in this case, I'm selecting all <AID> nodes under
// the <GroupAIDs> node - change to suit your needs
XmlNodeList aNodes = doc.SelectNodes("/Equipment/DataCollections/GroupAIDs/AID");

// loop through all AID nodes
foreach (XmlNode aNode in aNodes)
{
   // grab the "id" attribute
   XmlAttribute idAttribute = aNode.Attributes["id"];

   // check if that attribute even exists...
   if (idAttribute != null)
   {
      // if yes - read its current value
      string currentValue = idAttribute.Value;

      // here, you can now decide what to do - for demo purposes,
      // I just set the ID value to a fixed value if it was empty before
      if (string.IsNullOrEmpty(currentValue))
      {
         idAttribute.Value = "515";
      }
   }
}

// save the XmlDocument back to disk
doc.Save(@"D:\test2.xml");

You can migrate to XDocument instead of XmlDocument and then use Linq if you prefer that syntax. Something like:

var q = (from myConfig in xDoc.Elements("MyConfiguration")
         select myConfig.Attribute("SuperString").Value)
         .First();

Based on the other answers, I looked into XmlTextWriter and came up with the following helper method:

static public string Beautify(this XmlDocument doc)
{
    StringBuilder sb = new StringBuilder();
    XmlWriterSettings settings = new XmlWriterSettings
    {
        Indent = true,
        IndentChars = "  ",
        NewLineChars = "\r\n",
        NewLineHandling = NewLineHandling.Replace
    };
    using (XmlWriter writer = XmlWriter.Create(sb, settings)) {
        doc.Save(writer);
    }
    return sb.ToString();
}

It's a bit more code than I hoped for, but it works just peachy.

Here's the beginnings of a parser class to get you started. This ended up being my solution to a similar problem:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Xml.Linq;

namespace XML
{
    public class Parser
    {

        private string _FilePath = string.Empty;

        private XDocument _XML_Doc = null;


        public Parser(string filePath)
        {
            _FilePath = filePath;
            _XML_Doc = XDocument.Load(_FilePath);
        }

        public void ReplaceAtrribute(string attributeName, string newValue)
        {
            ReplaceAtrribute(string.Empty, attributeName, new List<string> { }, newValue);
        }

        }

        public void ReplaceAtrribute(string elementName, string attributeName, string oldValue, string newValue)
        {
            ReplaceAtrribute(elementName, attributeName, new List<string> { oldValue }, newValue);              
        }


        /// <summary>

        public void ReplaceAtrribute(string elementName, string attributeName, List<string> oldValues, string newValue)
        {
            List<XElement> elements = _XML_Doc.Elements().Descendants().ToList();

            foreach (XElement element in elements)
            {
                if (elementName == string.Empty | element.Name.LocalName.ToString() == elementName)
                {
                    if (element.Attribute(attributeName) != null)
                    {

                        if (oldValues.Count == 0 || oldValues.Contains(element.Attribute(attributeName).Value))
                        { element.Attribute(attributeName).Value = newValue; }
                    }
                }
            }

        }

        public void SaveChangesToFile()
        {
            _XML_Doc.Save(_FilePath);
        }

    }
}

I can give you two advices:

1. It seems you are using "LoadXml" instead of "Load" method. In some cases, it helps me.
2. You have an encoding problem. Could you check the encoding of the XML file and write it?

It's work for Iphone

<?php
  $browser = strpos($_SERVER['HTTP_USER_AGENT'],"iPhone");
  if ($browser == true){
    $browser = 'iphone';
  }
?>

Firstobject's free XML editor for Windows is called foxe is a great tool.

Open or paste your XML into it and press F8 to indent (you may need to set the number of indent spaces as it may default to 0).

It looks simple, however it contains a custom written XML parser written in C++ that allows it to work efficiently with very large XML files easily (unlike some expensive "espionage" related tools I've used).

From the product page:

The full Visual C++ source code for this firstobject XML editor (including the CDataEdit gigabyte edit control MFC component) is available as part of the Advanced CMarkup Developer License. It allows developers to implement custom XML handling functions such as validation, transformation, beautify, and reporting for their own purposes.

You can do that using Requestify, a very simple and cool HTTP client I wrote for nodeJS, it support easy use of cookies and it also supports caching.

To perform a request with a cookie attached just do the following:

var requestify = require('requestify');
requestify.post('http://google.com', {}, {
    cookies: {
        sessionCookie: 'session-cookie-data'   
    }
});

printf("\nmaximum of %d and %d is = %d",a,b,c);

Adapted from http://docs.python.org/library/sqlite3.html:

# Larger example
for t in [('2006-03-28', 'BUY', 'IBM', 1000, 45.00),
          ('2006-04-05', 'BUY', 'MSOFT', 1000, 72.00),
          ('2006-04-06', 'SELL', 'IBM', 500, 53.00),
         ]:
    c.execute('insert into stocks values (?,?,?,?,?)', t)

This worked for me On Windows 10,

xcopy /s {source drive..i.e. C:} {destination drive..i.e. D:} This will copy all the files and folders plus the folder contents.

This:

git log --oneline --grep='Searched phrase'

or this:

git log --oneline --name-status --grep='Searched phrase'

commands work best for me.

In my Angular Bootstrap dropdowns I initialize the JSON Array (vm.zoneDropdown) with ng-init (you can also have ng-init inside the directive template) and I pass the Array in a custom src attribute

<custom-dropdown control-id="zone" label="Zona" model="vm.form.zone" src="vm.zoneDropdown"
                         ng-init="vm.getZoneDropdownSrc()" is-required="true" form="farmaciaForm" css-class="custom-dropdown col-md-3"></custom-dropdown>

Inside the controller:

vm.zoneDropdown = [];
vm.getZoneDropdownSrc = function () {
    vm.zoneDropdown = $customService.getZone();
}

And inside the customDropdown directive template(note that this is only one part of the bootstrap dropdown):

<ul class="uib-dropdown-menu" role="menu" aria-labelledby="btn-append-to-body">
    <li role="menuitem" ng-repeat="dropdownItem in vm.src" ng-click="vm.setValue(dropdownItem)">
        <a ng-click="vm.preventDefault($event)" href="##">{{dropdownItem.text}}</a>
    </li>
</ul>

I was looking for a solution to remove strings' masks, specifically from Brazilian phones numbers, this post not answered but inspired me. This is my solution:

>>> phone_number = '+55(11)8715-9877'
>>> ''.join([n for n in phone_number if n.isdigit()])
'551187159877'

As a pure CSS solution for the close or 'times' symbol you can use the ISO code with the content property. I often use this for :after or :before pseudo selectors.

The content code is \00d7.

Example

div:after{
  display: inline-block;
  content: "\00d7"; /* This will render the 'X' */
}

You can then style and position the pseudo selector in any way you want. Hope this helps someone :).

Your closing your instance of the settings window right after you create it. You need to display the settings window first then wait for a dialog result. If it comes back as canceled then close the window. For Example:

private void button1_Click(object sender, EventArgs e)
{
    Settings newSettingsWindow = new Settings();

    if (newSettingsWindow.ShowDialog() == DialogResult.Cancel)
    {
        newSettingsWindow.Close();
    }
}

When installing the SDK I used this method:

curl https://sdk.cloud.google.com | bash

When using this method from the original author make sure you have accepted the security preferences in your mac settings to allow apps downloaded from app store and identified developers.

MVC defaults to DenyGet to protect you against a very specific attack involving JSON requests to improve the liklihood that the implications of allowing HTTP GET exposure are considered in advance of allowing them to occur.

This is opposed to afterwards when it might be too late.

Note: If your action method does not return sensitive data, then it should be safe to allow the get.

Further reading from my Wrox ASP.NET MVC3 book

By default, the ASP.NET MVC framework does not allow you to respond to an HTTP GET request with a JSON payload. If you need to send JSON in response to a GET, you'll need to explicitly allow the behavior by using JsonRequestBehavior.AllowGet as the second parameter to the Json method. However, there is a chance a malicious user can gain access to the JSON payload through a process known as JSON Hijacking. You do not want to return sensitive information using JSON in a GET request. For more details, see Phil's post at http://haacked.com/archive/2009/06/24/json-hijacking.aspx/ or this SO post.

Try to modify the eclipse.ini so that both Xms and Xmx are of the same value:

-Xms6000m
-Xmx6000m

This should force the Eclipse's VM to allocate 6GB of heap right from the beginning.

But be careful about either using the eclipse.ini or the command-line ./eclipse/eclipse -vmargs .... It should work in both cases but pick one and try to stick with it.

As of PowerShell 2, simple:

$recipients = $addresses -split "; "

Note that the right hand side is actually a case-insensitive regular expression, not a simple match. Use csplit to force case-sensitivity. See about_Split for more details.

Go to your Project properties (Project -> Properties -> Configuration Properties -> C/C++ -> General) and in the field Additional Include Directories add the path to your .h file.

And be sure that your Configuration and Platform are the active ones. Example: Configuration: Active(Debug) Platform: Active(Win32).

Further to the previous answers, the first thing I always do when thinking of issues like this is to create a small test application. Inside this app, perform some timing test for both scenarios and see for yourself which is quicker.

IMHO, appending 500+ string entries should definitely use StringBuilder.

For anyone who comes here, as I did, looking for the syntax to change origin to a different location you can find that documentation here: https://help.github.com/articles/changing-a-remote-s-url/. Using git remote add to do this will result in "fatal: remote origin already exists."

Nutshell: git remote set-url origin https://github.com/username/repo

(The marked answer is correct, I'm just hoping to help anyone as lost as I was... haha)

This will find all rows in the table that have errors, print out the row's primary key and the error that occurred on that row...

This is in C#, but converting it to VB should not be hard.

 foreach (DataRow dr in dataTable)
 {
   if (dr.HasErrors)
     {
        Debug.Write("Row ");
        foreach (DataColumn dc in dataTable.PKColumns)
          Debug.Write(dc.ColumnName + ": '" + dr.ItemArray[dc.Ordinal] + "', ");
        Debug.WriteLine(" has error: " + dr.RowError);
     }
  }

Oops - sorry PKColumns is something I added when I extended DataTable that tells me all the columns that make up the primary key of the DataTable. If you know the Primary Key columns in your datatable you can loop through them here. In my case, since all my datatables know their PK cols I can write debug for these errors automatically for all tables.

The output looks like this:

Row FIRST_NAME: 'HOMER', LAST_NAME: 'SIMPSON', MIDDLE_NAME: 'J',  has error: Column 'HAIR_COLOR' does not allow DBNull.Value.

If you're confused about the PKColumns section above - this prints out column names and values, and is not necessary, but adds helpful troubleshooting info for identifying which column values may be causing the issue. Removing this section and keeping the rest will still print the SQLite error being generated, which will note the column that has the problem.

You could descendingly order the tabele by id and limit the number of results to one:

SELECT id FROM tablename ORDER BY id DESC LIMIT 1

BUT: ORDER BY rearranges the entire table for this request. So if you have a lot of data and you need to repeat this operation several times, I would not recommend this solution.

Twitter Bootstrap Use collapse.js on table cells [Almost Done]

UPDATE:

Your fiddle wasn't loading jQuery, so anything worked.

I also added colspan='2' to the details row. But it's essentially your fiddle with jQuery loaded (in frameworks in the left column)

One cheeky solution :

  function printDiv(divID) {
        //Get the HTML of div
        var divElements = document.getElementById(divID).innerHTML;
        //Get the HTML of whole page
        var oldPage = document.body.innerHTML;
        //Reset the page's HTML with div's HTML only
        document.body.innerHTML = 
          "<html><head><title></title></head><body>" + 
          divElements + "</body>";
        //Print Page
        window.print();
        //Restore orignal HTML
        document.body.innerHTML = oldPage;

    }

HTML :

<form id="form1" runat="server">
    <div id="printablediv" style="width: 100%; background-color: Blue; height: 200px">
        Print me I am in 1st Div
    </div>
    <div id="donotprintdiv" style="width: 100%; background-color: Gray; height: 200px">
        I am not going to print
    </div>
    <input type="button" value="Print 1st Div" onclick="javascript:printDiv('printablediv')" />
</form>

Different database systems have different names for the same type of index, so be careful with this. For example, what SQL Server and Sybase call "clustered index" is called in Oracle an "index-organised table".

In my case I wanted to access an array inside a custom helper like so,

{{#ifCond arr.[@index] "foo" }}

Which did not work, but the answer suggested by @julesbou worked.

Working code:

{{#ifCond (lookup arr @index) "" }}

Hope this helps! Cheers.

Say:

sed "s|\$ROOT|${HOME}|" abc.sh

Note:

• Use double quotes so that the shell would expand variables.
• Use a separator different than / since the replacement contains /
• Escape the $ in the pattern since you don't want to expand it.

EDIT: In order to replace all occurrences of $ROOT, say

sed "s|\$ROOT|${HOME}|g" abc.sh

There are subtleties with Swifts === that go beyond mere pointer arithmetics. While in Objective-C you were able to compare any two pointers (i.e. NSObject *) with == this is no longer true in Swift since types play a much greater role during compilation.

A Playground will give you

1 === 2                    // false
1 === 1                    // true
let one = 1                // 1
1 === one                  // compile error: Type 'Int' does not conform to protocol 'AnyObject'
1 === (one as AnyObject)   // true (surprisingly (to me at least))

With strings we will have to get used to this:

var st = "123"                                 // "123"
var ns = (st as NSString)                      // "123"
st == ns                                       // true, content equality
st === ns                                      // compile error
ns === (st as NSString)                        // false, new struct
ns === (st as AnyObject)                       // false, new struct
(st as NSString) === (st as NSString)          // false, new structs, bridging is not "free" (as in "lunch")
NSString(string:st) === NSString(string:st)    // false, new structs
var st1 = NSString(string:st)                  // "123"
var st2 = st1                                  // "123"
st1 === st2                                    // true
var st3 = (st as NSString)                     // "123"
st1 === st3                                    // false
(st as AnyObject) === (st as AnyObject)        // false

but then you can also have fun as follows:

var st4 = st             // "123"
st4 == st                // true
st4 += "5"               // "1235"
st4 == st                // false, not quite a reference, copy on write semantics

I am sure you can think of a lot more funny cases :-)

Update for Swift 3 (as suggested by the comment from Jakub Truhlár)

1===2                                    // Compiler error: binary operator '===' cannot be applied to two 'Int' operands
(1 as AnyObject) === (2 as AnyObject)    // false
let two = 2
(2 as AnyObject) === (two as AnyObject)  // false (rather unpleasant)
(2 as AnyObject) === (2 as AnyObject)    // false (this makes it clear that there are new objects being generated)

This looks a little more consistent with Type 'Int' does not conform to protocol 'AnyObject', however we then get

type(of:(1 as AnyObject))                // _SwiftTypePreservingNSNumber.Type

but the explicit conversion makes clear that there might be something going on. On the String-side of things NSString will still be available as long as we import Cocoa. Then we will have

var st = "123"                                 // "123"
var ns = (st as NSString)                      // "123"
st == ns                                       // Compile error with Fixit: 'NSString' is not implicitly convertible to 'String'; did you mean to use 'as' to explicitly convert?
st == ns as String                             // true, content equality
st === ns                                      // compile error: binary operator '===' cannot be applied to operands of type 'String' and 'NSString'
ns === (st as NSString)                        // false, new struct
ns === (st as AnyObject)                       // false, new struct
(st as NSString) === (st as NSString)          // false, new structs, bridging is not "free" (as in "lunch")
NSString(string:st) === NSString(string:st)    // false, new objects
var st1 = NSString(string:st)                  // "123"
var st2 = st1                                  // "123"
st1 === st2                                    // true
var st3 = (st as NSString)                     // "123"
st1 === st3                                    // false
(st as AnyObject) === (st as AnyObject)        // false

It is still confusing to have two String classes, but dropping the implicit conversion will probably make it a little more palpable.

There are a couple ways to do this.

First, instead of going into openssl command prompt mode, just enter everything on one command line from the Windows prompt:

E:\> openssl x509 -pubkey -noout -in cert.pem  > pubkey.pem

If for some reason, you have to use the openssl command prompt, just enter everything up to the ">". Then OpenSSL will print out the public key info to the screen. You can then copy this and paste it into a file called pubkey.pem.

openssl> x509 -pubkey -noout -in cert.pem

Output will look something like this:

Perhaps something like this, assuming that there are many of these rows inside of the datatable and that each row is row:

List<string[]> MyStringArrays = new List<string[]>();
foreach( var row in datatable.rows )//or similar
{
 MyStringArrays.Add( new string[]{row.Name,row.Address,row.Age.ToString()} );
}

You could then access one:

MyStringArrays.ElementAt(0)[1]

If you use linqpad, here is a very simple scenario of your example:

class Datatable
{
 public List<data> rows { get; set; }
 public Datatable(){
  rows = new List<data>();
 }
}

class data
{
 public string Name { get; set; }
 public string Address { get; set; }
 public int Age { get; set; }
}

void Main()
{
 var datatable = new Datatable();
 var r = new data();
 r.Name = "Jim";
 r.Address = "USA";
 r.Age = 23;
 datatable.rows.Add(r);
 List<string[]> MyStringArrays = new List<string[]>();
 foreach( var row in datatable.rows )//or similar
 {
  MyStringArrays.Add( new string[]{row.Name,row.Address,row.Age.ToString()} );
 }
 var s = MyStringArrays.ElementAt(0)[1];
 Console.Write(s);//"USA"
}

Just skip the parameters. GDB doesn't need them:

gdb ./exe core.pid

Actually, the best solution is using JSON:

Documentation

JSON.parse(text[, reviver]);

Examples:

1)

var myobj = JSON.parse('{ "hello":"world" }');
alert(myobj.hello); // 'world'

2)

var myobj = JSON.parse(JSON.stringify({
    hello: "world"
});
alert(myobj.hello); // 'world'

3) Passing a function to JSON

var obj = {
    hello: "World",
    sayHello: (function() {
        console.log("I say Hello!");
    }).toString()
};
var myobj = JSON.parse(JSON.stringify(obj));
myobj.sayHello = new Function("return ("+myobj.sayHello+")")();
myobj.sayHello();

• go to dosbox installation directory (on my machine that is C:\Program Files (x86)\DOSBox-0.74 ) as you see the version number is part of the installation directory name.

• run "DOSBox 0.74 Options.bat"

• the script starts notepad with configuration file: here change

  windowresolution=1600x800

  output=ddraw

(the resolution can't be changed if output=surface - that's the default).

• safe configuration file changes.

We had exactly the same challenge some time ago. We wanted to go with CEF3 open source library which is WPF-based and supports .NET 3.5.

Firstly, the author of CEF himself listed binding for different languages here.

Secondly, we went ahead with open source .NET CEF3 binding which is called Xilium.CefGlue and had a good success with it. In cases where something is not working as you'd expect, author usually very responsive to the issues opened in build-in bitbucket tracker

So far it has served us well. Author updates his library to support latest CEF3 releases and bug fixes on regular bases.

If you want the onload method to take parameters, you can do something similar to this:

window.onload = function() {
  yourFunction(param1, param2);
};

This binds onload to an anonymous function, that when invoked, will run your desired function, with whatever parameters you give it. And, of course, you can run more than one function from inside the anonymous function.

Generally, this is how you open an OS folder containing a bunch of vdmk files on VMware Player.

use like this:

<hr style="border-bottom:dotted" />

I spent a lot of time trying different answers all around the internet, and I suspect the reasons why one thing works for some people and not for others is due to very small weird differences in application. For context, I needed to read in file names from a csv file that had strange and/or unmappable unicode characters and write them to a new csv file. For what it's worth, here's what worked for me:

s = '\u00e7\u00a3\u0085\u00e5\u008d\u0095' # csv freaks if you try to write this
s = repr(s.encode('utf-8', 'ignore'))[2:-1]

My VirtualHost's ServerName was commented out by default. It worked after uncommenting.

Change your network adapter to a bridged connection, this will directly connect to your computers physical network.

Have you tried setting the painted border false?

JButton button = new JButton();
button.setBackground(Color.red);

It works on my mac :)

You will simply need to do a type check for each of the basic numeric types.

Here's an extension method that should do the job:

public static bool IsNumber(this object value)
{
    return value is sbyte
            || value is byte
            || value is short
            || value is ushort
            || value is int
            || value is uint
            || value is long
            || value is ulong
            || value is float
            || value is double
            || value is decimal;
}

This should cover all numeric types.

Update

It seems you do actually want to parse the number from a string during deserialisation. In this case, it would probably just be best to use double.TryParse.

string value = "123.3";
double num;
if (!double.TryParse(value, out num))
    throw new InvalidOperationException("Value is not a number.");

Of course, this wouldn't handle very large integers/long decimals, but if that is the case you just need to add additional calls to long.TryParse / decimal.TryParse / whatever else.

If you add the following attribute to your activity's manifest definition, it will completely suppress the keyboard from popping when your activity opens. Hopefully this helps:

(Add to your Activity's manifest definition):

android:windowSoftInputMode="stateHidden"

You can always run this:

java -cp HelloWorld.jar HelloWorld

-cp HelloWorld.jar adds the jar to the classpath, then HelloWorld runs the class you wrote.

To create a runnable jar with a main class with no package, add Class-Path: . to the manifest:

Manifest-Version: 1.0
Class-Path: .
Main-Class: HelloWorld

I would advise using a package to give your class its own namespace. E.g.

package com.stackoverflow.user.blrp;

public class HelloWorld {
    ...
}

Specify the Class Card for the constructor-:

void Card::Card(Card::Rank rank, Card::Suit suit) {

And also define the default constructor and destructor.

I'd rather tab indentation not work than breaking tabbing between form items.

If you want to indent to put in code in the Markdown box, use Ctrl+K (or ?K on a Mac).

In terms of actually stopping the action, jQuery (which Stack Overflow uses) will stop an event from bubbling when you return false from an event callback. This makes life easier for working with multiple browsers.

I'd like to post some important information about undefined, which beginners might not know.

Look at the following code:

 /* 
  * Consider there is no code above. 
  * The browser runs these lines only.
  */

   // var a;  
   // --- commented out to point that we've forgotten to declare `a` variable 

   if ( a === undefined ) {
       alert('Not defined');
   } else {
       alert('Defined: ' + a);
   }

   alert('Doing important job below');

If you run this code, where variable a HAS NEVER BEEN DECLARED using var, you will get an ERROR EXCEPTION and surprisingly see no alerts at all.

Instead of 'Doing important job below', your script will TERMINATE UNEXPECTEDLY, throwing unhandled exception on the very first line.

Here is the only bulletproof way to check for undefined using typeof keyword, which was designed just for such purpose:

   /* 
    * Correct and safe way of checking for `undefined`: 
    */

   if ( typeof a === 'undefined' ) {
       alert(
           'The variable is not declared in this scope, \n' +
           'or you are pointing to unexisting property, \n' +
           'or no value has been set yet to the variable, \n' + 
           'or the value set was `undefined`. \n' +
           '(two last cases are equivalent, don\'t worry if it blows out your mind.'
           );
   }

   /* 
    *  Use `typeof` for checking things like that
    */

This method works in all possible cases.

The last argument to use it is that undefined can be potentially overwritten in earlier versions of Javascript:

     /* @ Trollface @ */
        undefined = 2;
     /* Happy debuging! */  

Hope I was clear enough.

As pointed out by others, the concept of a vertical rule does not fit in with the original ideas behind the structure and presentation of HTML documents. However, these days (especially with the proliferation of web-apps) there are is a small number of scenarios where this would indeed be useful.

For example, consider a horizontal navigation menu fixed at the top of the screen, similar to the menu-bar in most windowed GUI applications. You have several top-level menu items arranged from left-to-right which when clicked open up drop-down menus. Years ago, it was common practice to create this with a single-row table, but this is bad HTML and it is widely recognised that the correct way to go would be a list with heavily customised CSS.

Now, say you want to group similar items, but add a vertical separator in between groups, to achieve something like this:

[Item 1a] [Item 1b] | [Item 2a] [Item 2b]

Using <hr style="width: 1px; height: 100%; ..." /> works, but may be considered semantically incorrect as you are changing what that element is actually for. Furthermore, you can't use this within certain elements where the HTML DTD allows only inline-level elements (e.g. within a <span> element).

A better option would be <span style="display: inline-block; width:1px; height:100%; background:#000; margin: 0 2px;"></span>, however not all browsers support the display: inline-block; CSS property, so the only real inline-level option is to use an image like so:

<img src="pixel.gif" alt="|" style="width:1px; height:100%; background:#000; margin: 0 2px;" />

This has the added advantage of being compatible with text-only browsers (like lynx) as the pipe character is displayed instead of the image. (It still annoys me that M$IE incorrectly uses alt text as a tooltip; that's what the title attribute is for!)

for me the only thing that works is:

CREATE FUNCTION IsNumeric (SIN VARCHAR(1024)) RETURNS TINYINT
RETURN SIN REGEXP '^(-|\\+){0,1}([0-9]+\\.[0-9]*|[0-9]*\\.[0-9]+|[0-9]+)$';

from kevinclark all other return useless stuff for me in case of 234jk456 or 12 inches

Please use

.FirstOrDefault()

because if in the first row of the result there is no info this instruction goes to the default info.

It happens when your password is missing.

Steps to change password when you have forgotten:

1. Stop MySQL Server (on Linux):

   sudo systemctl stop mysql
   

2. Start the database without loading the grant tables or enabling networking:

   sudo mysqld_safe --skip-grant-tables --skip-networking &
   

   The ampersand at the end of this command will make this process run in the
   background so you can continue to use your terminal and run #mysql -u root, it will not ask for password.

   If you get error like as below:

   2018-02-12T08:57:39.826071Z mysqld_safe Directory '/var/run/mysqld' for UNIX
   socket file don't exists. mysql -u root ERROR 2002 (HY000): Can't connect to local MySQL server through socket
   '/var/run/mysqld/mysqld.sock' (2) [1]+ Exit 1

3. Make MySQL service directory.

   sudo mkdir /var/run/mysqld
   

   Give MySQL user permission to write to the service directory.

   sudo chown mysql: /var/run/mysqld
   

4. Run the same command in step 2 to run mysql in background.

5. Run mysql -u root you will get mysql console without entering password.

   Run these commands

   FLUSH PRIVILEGES;
   

   For MySQL 5.7.6 and newer

   ALTER USER 'root'@'localhost' IDENTIFIED BY 'new_password';
   

   For MySQL 5.7.5 and older

   SET PASSWORD FOR 'root'@'localhost' = PASSWORD('new_password');
   

   If the ALTER USER command doesn't work use:

   UPDATE mysql.user SET authentication_string = PASSWORD('new_password')     WHERE User = 'root' AND Host = 'localhost';
   

Now exit

6. To stop instance started manually

   sudo kill `cat /var/run/mysqld/mysqld.pid`
   

7. Restart mysql

   sudo systemctl start mysql
   

        li.Where(w => w.name == "di" )
          .Select(s => { s.age = 10; return s; })
          .ToList();

Please try the below XAML snippet:

<Button Width="300" Height="50">
  <StackPanel Orientation="Horizontal">
    <Image Source="Pictures/img.jpg" Width="20" Height="20"/>
    <TextBlock Text="Blablabla" VerticalAlignment="Center" />
  </StackPanel>
</Button>

In XAML elements are in a tree structure. So you have to add the child control to its parent control. The below code snippet also works fine. Give a name for your XAML root grid as 'MainGrid'.

Image img = new Image();
img.Source = new BitmapImage(new Uri(@"foo.png"));

StackPanel stackPnl = new StackPanel();
stackPnl.Orientation = Orientation.Horizontal;
stackPnl.Margin = new Thickness(10);
stackPnl.Children.Add(img);

Button btn = new Button();
btn.Content = stackPnl;
MainGrid.Children.Add(btn);

I've just had the same problem (with Python 2.7 and PIL for this versions, but the solution should work also for 2.6) and the way to solve it is to copy all the registry keys from:

Use this line of code when scanning the second value: scanf(" %lf", &b); also replace all %ld with %lf.

It's a problem related with input stream buffer. You can also use fflush(stdin); after the first scanning to clear the input buffer and then the second scanf will work as expected. An alternate way is place a getch(); or getchar(); function after the first scanf line.

if you are using GridView you can use something like Ian Hickson's solution.

I don't know why there are 48 upvotes for @Chris Schmitz answer which is not 100% correct.

Month is in form of array and starts from 0 so to get exact value we should use 1 + moment().month()

What I usually do, is to store the full string into a variable first, like so:

<?php
$img_id = 'data:image/png;base64,iVBORw0KGgoAAAAAAAAyCAY...';
?>

Then, where I want either JS to do something with that variable:

<script type="text/javascript">
document.getElementById("img_id").backgroundImage="url('<?php echo $img_id; ?>')";
</script>

You could reference the same variable via PHP directly using something like:

<img src="<?php echo $img_id; ?>">

Works for me ;)

You can use flexbox for this.

ul {
    display: flex;
    align-items: center;
}

A detailed explanation of how to use flexbox can be found here.

It explains the pros and cons of different methods of creating PreparedStatement with in clause.

EDIT:

An obvious approach is to dynamically generate the '?' part at runtime, but I don't want to merely suggest just this approach because depending on the way you use it, it might be inefficient (since the PreparedStatement will need to be 'compiled' every time it gets used)

By using Collections.sort(), we can sort a list.

public class EmployeeList {

    public static void main(String[] args) {
        // TODO Auto-generated method stub

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

        empNames.add("sudheer");
        empNames.add("kumar");
        empNames.add("surendra");
        empNames.add("kb");

        if(!empNames.isEmpty()){

            for(String emp:empNames){

                System.out.println(emp);
            }

            Collections.sort(empNames);

            System.out.println(empNames);
        }
    }
}

output:

sudheer
kumar
surendra
kb
[kb, kumar, sudheer, surendra]

NERDTree opens up in another window. That split view you're seeing? They're called windows in vim parlance. All the window commands start with CTRL-W. To move from adjacent windows that are left and right of one another, you can change focus to the window to the left of your current window with CTRL-w h, and move focus to the right with CTRL-w l. Likewise, CTRL-w j and CTRL-w k will move you between horizontally split windows (i.e., one window is above the other). There's a lot more you can do with windows as described here.

You can also use the :NERDTreeToggle command to make your tree open and close. I usually bind that do t.

You can easily verify your instance is an array or not by the following function.

func verifyIsObjectOfAnArray<T>(_ object: T) -> Bool {
   if let _ = object as? [T] {
      return true
   }

   return false
}

Even you can access it as follows. You will receive nil if the object wouldn't be an array.

func verifyIsObjectOfAnArray<T>(_ object: T) -> [T]? {
   if let array = object as? [T] {
      return array
   }

   return nil
}

We can use replace to change the values in 'mpg' to NA that corresponds to cyl==4.

mtcars %>%
     mutate(mpg=replace(mpg, cyl==4, NA)) %>%
     as.data.frame()

By default, scripts can't handle imports like that directly. You're probably getting another error about not being able to get Course or not doing the import.

If you add type="module" to your <script> tag, and change the import to ./course.js (because browsers won't auto-append the .js portion), then the browser will pull down course for you and it'll probably work.

import './course.js';

function Student() {
    this.firstName = '';
    this.lastName = '';
    this.course = new Course();
}

<html>
    <head>
        <script src="./models/student.js" type="module"></script>
    </head>
    <body>
        <div id="myDiv">
        </div>
        <script>
        window.onload= function() {
            var x = new Student();
            x.course.id = 1;
            document.getElementById('myDiv').innerHTML = x.course.id;
        }
        </script>

If you're serving files over file://, it likely won't work. Some IDEs have a way to run a quick sever.

You can also write a quick express server to serve your files (install Node if you don't have it):

//package.json
{
  "scripts": { "start": "node server" },
  "dependencies": { "express": "latest" }
}

// server/index.js
const express = require('express');
const app = express();

app.use('/', express.static('PATH_TO_YOUR_FILES_HERE');
app.listen(8000);

With those two files, run npm install, then npm start and you'll have a server running over http://localhost:8000 which should point to your files.

This one worked for me:

>> print(df)
                          TotalVolume  Symbol
2016-04-15 09:00:00       108400       2802.T
2016-04-15 09:05:00       50300        2802.T

>> print(df.set_index(pd.to_datetime(df.index.values) - datetime(2016, 4, 15)))

             TotalVolume  Symbol
09:00:00     108400       2802.T
09:05:00     50300        2802.T

This issue comes when trust verification of app fails.

You can trust app from Settings shown in below images.

If this dosen't work then delete app and re-install it.

For your first method change ws.Range("A") to ws.Range("A:A") which will search the entirety of column a, like so:

Sub Find_Bingo()

        Dim wb As Workbook
        Dim ws As Worksheet
        Dim FoundCell As Range
        Set wb = ActiveWorkbook
        Set ws = ActiveSheet

            Const WHAT_TO_FIND As String = "Bingo"

            Set FoundCell = ws.Range("A:A").Find(What:=WHAT_TO_FIND)
            If Not FoundCell Is Nothing Then
                MsgBox (WHAT_TO_FIND & " found in row: " & FoundCell.Row)
            Else
                MsgBox (WHAT_TO_FIND & " not found")
            End If
End Sub

For your second method, you are using Bingo as a variable instead of a string literal. This is a good example of why I add Option Explicit to the top of all of my code modules, as when you try to run the code it will direct you to this "variable" which is undefined and not intended to be a variable at all.

Additionally, when you are using With...End With you need a period . before you reference Cells, so Cells should be .Cells. This mimics the normal qualifying behavior (i.e. Sheet1.Cells.Find..)

Change Bingo to "Bingo" and change Cells to .Cells

With Sheet1
        Set FoundCell = .Cells.Find(What:="Bingo", After:=.Cells(1, 1), _
        LookIn:=xlValues, lookat:=xlPart, SearchOrder:=xlByRows, _
        SearchDirection:=xlNext, MatchCase:=False, SearchFormat:=False)
    End With

If Not FoundCell Is Nothing Then
        MsgBox ("""Bingo"" found in row " & FoundCell.Row)
Else
        MsgBox ("Bingo not found")
End If

Update

In my

With Sheet1
    .....
End With

The Sheet1 refers to a worksheet's code name, not the name of the worksheet itself. For example, say I open a new blank Excel workbook. The default worksheet is just Sheet1. I can refer to that in code either with the code name of Sheet1 or I can refer to it with the index of Sheets("Sheet1"). The advantage to using a codename is that it does not change if you change the name of the worksheet.

Continuing this example, let's say I renamed Sheet1 to Data. Using Sheet1 would continue to work, as the code name doesn't change, but now using Sheets("Sheet1") would return an error and that syntax must be updated to the new name of the sheet, so it would need to be Sheets("Data").

In the VB Editor you would see something like this:

Notice how, even though I changed the name to Data, there is still a Sheet1 to the left. That is what I mean by codename.

The Data worksheet can be referenced in two ways:

Debug.Print Sheet1.Name
Debug.Print Sheets("Data").Name

Both should return Data

More discussion on worksheet code names can be found here.

The Homebrew package manager includes launchctl plists to start automatically. For more information, run brew info postgres.

Start manually

pg_ctl -D /usr/local/var/postgres start

Stop manually

pg_ctl -D /usr/local/var/postgres stop

Start automatically

"To have launchd start postgresql now and restart at login:"

brew services start postgresql

What is the result of pg_ctl -D /usr/local/var/postgres -l /usr/local/var/postgres/server.log start?

What is the result of pg_ctl -D /usr/local/var/postgres status?

Are there any error messages in the server.log?

Make sure tcp localhost connections are enabled in pg_hba.conf:

# IPv4 local connections:
host    all    all    127.0.0.1/32    trust

Check the listen_addresses and port in postgresql.conf:

egrep 'listen|port' /usr/local/var/postgres/postgresql.conf

#listen_addresses = 'localhost'        # What IP address(es) to listen on;
#port = 5432                # (change requires restart)

Cleaning up

PostgreSQL was most likely installed via Homebrew, Fink, MacPorts or the EnterpriseDB installer.

Check the output of the following commands to determine which package manager it was installed with:

brew && brew list|grep postgres
fink && fink list|grep postgres
port && port installed|grep postgres

So it looks like there are a few things going wrong here. Based on your post it looks like you are attempting to support file uploads using the connect-multiparty middleware. What this middleware does is take the uploaded file, write it to the local filesystem and then sets req.files to the the uploaded file(s).

The configuration of your route looks fine, the problem looks to be with your items.upload() function. In particular with this part:

var params = {
  Key: file.name,
  Body: file
};

As I mentioned at the beginning of my answer connect-multiparty writes the file to the local filesystem, so you'll need to open the file and read it, then upload it, and then delete it on the local filesystem.

That said you could update your method to something like the following:

var fs = require('fs');
exports.upload = function (req, res) {
    var file = req.files.file;
    fs.readFile(file.path, function (err, data) {
        if (err) throw err; // Something went wrong!
        var s3bucket = new AWS.S3({params: {Bucket: 'mybucketname'}});
        s3bucket.createBucket(function () {
            var params = {
                Key: file.originalFilename, //file.name doesn't exist as a property
                Body: data
            };
            s3bucket.upload(params, function (err, data) {
                // Whether there is an error or not, delete the temp file
                fs.unlink(file.path, function (err) {
                    if (err) {
                        console.error(err);
                    }
                    console.log('Temp File Delete');
                });

                console.log("PRINT FILE:", file);
                if (err) {
                    console.log('ERROR MSG: ', err);
                    res.status(500).send(err);
                } else {
                    console.log('Successfully uploaded data');
                    res.status(200).end();
                }
            });
        });
    });
};

What this does is read the uploaded file from the local filesystem, then uploads it to S3, then it deletes the temporary file and sends a response.

There's a few problems with this approach. First off, it's not as efficient as it could be, as for large files you will be loading the entire file before you write it. Secondly, this process doesn't support multi-part uploads for large files (I think the cut-off is 5 Mb before you have to do a multi-part upload).

What I would suggest instead is that you use a module I've been working on called S3FS which provides a similar interface to the native FS in Node.JS but abstracts away some of the details such as the multi-part upload and the S3 api (as well as adds some additional functionality like recursive methods).

If you were to pull in the S3FS library your code would look something like this:

var fs = require('fs'),
    S3FS = require('s3fs'),
    s3fsImpl = new S3FS('mybucketname', {
        accessKeyId: XXXXXXXXXXX,
        secretAccessKey: XXXXXXXXXXXXXXXXX
    });

// Create our bucket if it doesn't exist
s3fsImpl.create();

exports.upload = function (req, res) {
    var file = req.files.file;
    var stream = fs.createReadStream(file.path);
    return s3fsImpl.writeFile(file.originalFilename, stream).then(function () {
        fs.unlink(file.path, function (err) {
            if (err) {
                console.error(err);
            }
        });
        res.status(200).end();
    });
};

What this will do is instantiate the module for the provided bucket and AWS credentials and then create the bucket if it doesn't exist. Then when a request comes through to upload a file we'll open up a stream to the file and use it to write the file to S3 to the specified path. This will handle the multi-part upload piece behind the scenes (if needed) and has the benefit of being done through a stream, so you don't have to wait to read the whole file before you start uploading it.

If you prefer, you could change the code to callbacks from Promises. Or use the pipe() method with the event listener to determine the end/errors.

If you're looking for some additional methods, check out the documentation for s3fs and feel free to open up an issue if you are looking for some additional methods or having issues.

To dynamically change the color of a text box goto properties, goto font/Color and set the following expression

=SWITCH(Fields!CurrentRiskLevel.Value = "Low", "Green",
Fields!CurrentRiskLevel.Value = "Moderate", "Blue",
Fields!CurrentRiskLevel.Value = "Medium", "Yellow",
Fields!CurrentRiskLevel.Value = "High", "Orange",
Fields!CurrentRiskLevel.Value = "Very High", "Red"
)

Same way for tolerance

=SWITCH(Fields!Tolerance.Value = "Low", "Red",
Fields!Tolerance.Value = "Moderate", "Orange",
Fields!Tolerance.Value = "Medium", "Yellow",
Fields!Tolerance.Value = "High", "Blue",
Fields!Tolerance.Value = "Very High", "Green")

xlsx2csv is faster than pandas and xlrd.

xlsx2csv -s 0 crunchbase_monthly_.xlsx cruchbase

excel file usually comes with n sheetname.

-s is sheetname index.

then, cruchbase folder will be created, each sheet belongs to xlsx will be converted to a single csv.

p.s. csvkit is awesome too.

I succinctified Poyson 1's answer like so:

public static bool IsValidEmailAddress(string candidateEmailAddr)
{
    string regexExpresion = "\\w+([-+.']\\w+)*@\\w+([-.]\\w+)*\\.\\w+([-.]\\w+)*";
    return (Regex.IsMatch(candidateEmailAddr, regexExpresion)) && 
           (Regex.Replace(candidateEmailAddr, regexExpresion, string.Empty).Length == 0);
}

To those who are wondering if they should or not use event.which in vanilla JS or Angular : It's now deprecated so prefer using event.buttons instead.

Note : With this method and (mousedown) event:

• left click press is associated to 1
• right click press is associated to 2
• scroll button press is associated with 4

and (mouseup) event will NOT return the same numbers but 0 instead.

Source : https://developer.mozilla.org/en-US/docs/Web/API/MouseEvent/buttons

No events get triggered when the element is having disabled attribute.

None of the below will get triggered.

$("[disabled]").click( function(){ console.log("clicked") });//No Impact
$("[disabled]").hover( function(){ console.log("hovered") });//No Impact
$("[disabled]").dblclick( function(){ console.log("double clicked") });//No Impact

While readonly will be triggered.

$("[readonly]").click( function(){ console.log("clicked") });//log - clicked
$("[readonly]").hover( function(){ console.log("hovered") });//log - hovered
$("[readonly]").dblclick( function(){ console.log("double clicked") });//log - double clicked

//create a variable that contain your button
Button button = (Button) findViewById(R.id.button);

    button.setOnClickListener(new OnClickListener(){
        @Override
        //On click function
        public void onClick(View view) {
            //Create the intent to start another activity
            Intent intent = new Intent(view.getContext(), AnotherActivity.class);
            startActivity(intent);
        }
    });

Try the code below and.....

1 - change the name of the MENU as in my sample the menuitem was called 'Form7ToolStripMenuItem_Click'

2 - make SURE to paste it into an MDIFORM and not just a basic FORM

Then let me know if the CHILD form still shows OUTSIDE the parent form

Private Sub Form7ToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Form7ToolStripMenuItem.Click

    Dim NewForm As System.Windows.Forms.Form
    NewForm = New System.Windows.Forms.Form
    'USE THE NEXT LINE - to add an existing CUSTOM form you already have
    'NewForm = Form7                         
    NewForm.Width = 400
    NewForm.Height = 250
    NewForm.MdiParent = Me
    NewForm.Text = "CAPTION"
    NewForm.Show()
    DockChildForm(NewForm, "left")          'dock left
    'DockChildForm(NewForm, "right")         'dock right
    'DockChildForm(NewForm, "top")           'dock top
    'DockChildForm(NewForm, "bottom")        'doc bottom
    'DockChildForm(NewForm, "full")          'fill the client area (maximise the child INSIDE the parent)
    'DockChildForm(NewForm, "Anything-Else") 'center the form

End Sub

Private Sub DockChildForm(ByRef Form2Dock As Form, ByVal Position As String)

    Dim XYpoint As Point
    Select Case Position
        Case "left"
            Form2Dock.Dock = DockStyle.Left
        Case "top"
            Form2Dock.Dock = DockStyle.Top
        Case "right"
            Form2Dock.Dock = DockStyle.Right
        Case "bottom"
            Form2Dock.Dock = DockStyle.Bottom
        Case "full"
            Form2Dock.Dock = DockStyle.Fill
        Case Else
            XYpoint = New Point
            XYpoint.X = ((Me.ClientSize.Width - Form2Dock.Width) / 2)
            XYpoint.Y = ((Me.ClientSize.Height - Form2Dock.Height) / 2)
            Form2Dock.Location = XYpoint
    End Select
End Sub

I like lambda :)

 private void ClearTextBoxes()
 {
     Action<Control.ControlCollection> func = null;

     func = (controls) =>
         {
             foreach (Control control in controls)
                 if (control is TextBox)
                     (control as TextBox).Clear();
                 else
                     func(control.Controls);
         };

     func(Controls);
 }

Good luck!

Here's an adaptation of CD Sanchez' answer that consistently returns a 6-digit colour code:

var stringToColour = function(str) {
  var hash = 0;
  for (var i = 0; i < str.length; i++) {
    hash = str.charCodeAt(i) + ((hash << 5) - hash);
  }
  var colour = '#';
  for (var i = 0; i < 3; i++) {
    var value = (hash >> (i * 8)) & 0xFF;
    colour += ('00' + value.toString(16)).substr(-2);
  }
  return colour;
}

Usage:

stringToColour("greenish");
// -> #9bc63b

Example:

http://jsfiddle.net/sUK45/

(An alternative/simpler solution might involve returning an 'rgb(...)'-style colour code.)

GitHub upstream.

Compile:

gcc -ggdb3 -O0 -o main -std=c99 -Wall -Wextra -pedantic main.c -lGL -lGLU -lglut

Run with glOrtho:

./main 1

Run with glFrustrum:

./main

Tested on Ubuntu 18.10.

Schema

Ortho: camera is a plane, visible volume a rectangle:

Frustrum: camera is a point,visible volume a slice of a pyramid:

Image source.

Parameters

We are always looking from +z to -z with +y upwards:

glOrtho(left, right, bottom, top, near, far)

• left: minimum x we see
• right: maximum x we see
• bottom: minimum y we see
• top: maximum y we see
• -near: minimum z we see. Yes, this is -1 times near. So a negative input means positive z.
• -far: maximum z we see. Also negative.

Schema:

Image source.

How it works under the hood

In the end, OpenGL always "uses":

glOrtho(-1.0, 1.0, -1.0, 1.0, -1.0, 1.0);

If we use neither glOrtho nor glFrustrum, that is what we get.

glOrtho and glFrustrum are just linear transformations (AKA matrix multiplication) such that:

• glOrtho: takes a given 3D rectangle into the default cube
• glFrustrum: takes a given pyramid section into the default cube

This transformation is then applied to all vertexes. This is what I mean in 2D:

Image source.

The final step after transformation is simple:

• remove any points outside of the cube (culling): just ensure that x, y and z are in [-1, +1]
• ignore the z component and take only x and y, which now can be put into a 2D screen

With glOrtho, z is ignored, so you might as well always use 0.

One reason you might want to use z != 0 is to make sprites hide the background with the depth buffer.

Deprecation

glOrtho is deprecated as of OpenGL 4.5: the compatibility profile 12.1. "FIXED-FUNCTION VERTEX TRANSFORMATIONS" is in red.

So don't use it for production. In any case, understanding it is a good way to get some OpenGL insight.

Modern OpenGL 4 programs calculate the transformation matrix (which is small) on the CPU, and then give the matrix and all points to be transformed to OpenGL, which can do the thousands of matrix multiplications for different points really fast in parallel.

Manually written vertex shaders then do the multiplication explicitly, usually with the convenient vector data types of the OpenGL Shading Language.

Since you write the shader explicitly, this allows you to tweak the algorithm to your needs. Such flexibility is a major feature of more modern GPUs, which unlike the old ones that did a fixed algorithm with some input parameters, can now do arbitrary computations.

Output:

The matrix for glOrtho is really simple, composed only of scaling and translation:

scalex, 0,      0,      translatex,
0,      scaley, 0,      translatey,
0,      0,      scalez, translatez,
0,      0,      0,      1

as mentioned in the OpenGL 2 docs.

The glFrustum matrix is not too hard to calculate by hand either, but starts getting annoying. Note how frustum cannot be made up with only scaling and translations like glOrtho, more info at: https://gamedev.stackexchange.com/a/118848/25171

The GLM OpenGL C++ math library is a popular choice for calculating such matrices. http://glm.g-truc.net/0.9.2/api/a00245.html documents both an ortho and frustum operations.

MySQL can record linebreaks just fine in most cases, but the problem is, you need <br /> tags in the actual string for your browser to show the breaks. Since you mentioned PHP, you can use the nl2br() function to convert a linebreak character ("\n") into HTML <br /> tag.

Just use it like this:

<?php
echo nl2br("Hello, World!\n I hate you so much");
?>

Output (in HTML):

Hello, World!<br>I hate you so much

Here's a link to the manual: http://php.net/manual/en/function.nl2br.php

When you write x = 0, x is an int...so you can't do x[age1] because x is int

I needed to exclude an auditing @Aspect @Component from the app context but only for a few test classes. I ended up using @Profile("audit") on the aspect class; including the profile for normal operations but excluding it (don't put it in @ActiveProfiles) on the specific test classes.

First let me mention that you probably don't want to create a file object that eventually can be opened for reading OR writing, depending on a non-reproducible condition. You need to know which methods can be used, reading or writing, which depends on what you want to do with the fileobject.

That said, you can do it as That One Random Scrub proposed, using try: ... except:. Actually that is the proposed way, according to the python motto "It's easier to ask for forgiveness than permission".

But you can also easily test for existence:

import os
# open file for reading
fn = raw_input("Enter file to open: ")
if os.path.exists(fn):
    fh = open(fn, "r")
else:
    fh = open(fn, "w")

Note: use raw_input() instead of input(), because input() will try to execute the entered text. If you accidently want to test for file "import", you'd get a SyntaxError.

1. Using the x509 module
openssl x509 ...
...

2 Using the ca module
openssl ca ...
...

You are missing the prelude to those commands.

This is a two-step process. First you set up your CA, and then you sign an end entity certificate (a.k.a server or user). Both of the two commands elide the two steps into one. And both assume you have a an OpenSSL configuration file already setup for both CAs and Server (end entity) certificates.

First, create a basic configuration file:

$ touch openssl-ca.cnf

Then, add the following to it:

HOME            = .
RANDFILE        = $ENV::HOME/.rnd

subjectKeyIdentifier   = hash
authorityKeyIdentifier = keyid:always, issuer
basicConstraints       = critical, CA:true
keyUsage               = keyCertSign, cRLSign

The fields above are taken from a more complex openssl.cnf (you can find it in /usr/lib/openssl.cnf), but I think they are the essentials for creating the CA certificate and private key.

Tweak the fields above to suit your taste. The defaults save you the time from entering the same information while experimenting with configuration file and command options.

I omitted the CRL-relevant stuff, but your CA operations should have them. See openssl.cnf and the related crl_ext section.

Then, execute the following. The -nodes omits the password or passphrase so you can examine the certificate. It's a really bad idea to omit the password or passphrase.

$ openssl req -x509 -config openssl-ca.cnf -newkey rsa:4096 -sha256 -nodes -out cacert.pem -outform PEM

After the command executes, cacert.pem will be your certificate for CA operations, and cakey.pem will be the private key. Recall the private key does not have a password or passphrase.

You can dump the certificate with the following.

$ openssl x509 -in cacert.pem -text -noout

For part two, I'm going to create another configuration file that's easily digestible. First, touch the openssl-server.cnf (you can make one of these for user certificates also).

$ touch openssl-server.cnf

Then open it, and add the following.

HOME            = .
RANDFILE        = $ENV::HOME/.rnd

If you are developing and need to use your workstation as a server, then you may need to do the following for Chrome. Otherwise Chrome may complain a Common Name is invalid (ERR_CERT_COMMON_NAME_INVALID). I'm not sure what the relationship is between an IP address in the SAN and a CN in this instance.

# IPv4 localhost
IP.1     = 127.0.0.1

# IPv6 localhost
IP.2     = ::1

Then, create the server certificate request. Be sure to omit -x509*. Adding -x509 will create a certificate, and not a request.

$ openssl req -config openssl-server.cnf -newkey rsa:2048 -sha256 -nodes -out servercert.csr -outform PEM

After this command executes, you will have a request in servercert.csr and a private key in serverkey.pem.

And you can inspect it again.

$ openssl req -text -noout -verify -in servercert.csr

Next, you have to sign it with your CA.

You are almost ready to sign the server's certificate by your CA. The CA's openssl-ca.cnf needs two more sections before issuing the command.

First, open openssl-ca.cnf and add the following two sections.

####################################################################
[ signing_policy ]
countryName            = optional
stateOrProvinceName    = optional
localityName           = optional
organizationName       = optional
organizationalUnitName = optional
commonName             = supplied
emailAddress           = optional

####################################################################
[ signing_req ]
subjectKeyIdentifier   = hash
authorityKeyIdentifier = keyid,issuer
basicConstraints       = CA:FALSE
keyUsage               = digitalSignature, keyEncipherment

Second, add the following to the [ CA_default ] section of openssl-ca.cnf. I left them out earlier, because they can complicate things (they were unused at the time). Now you'll see how they are used, so hopefully they will make sense.

base_dir      = .
certificate   = $base_dir/cacert.pem   # The CA certifcate
private_key   = $base_dir/cakey.pem    # The CA private key
new_certs_dir = $base_dir              # Location for new certs after signing
database      = $base_dir/index.txt    # Database index file
serial        = $base_dir/serial.txt   # The current serial number

unique_subject = no  # Set to 'no' to allow creation of
                     # several certificates with same subject.

Third, touch index.txt and serial.txt:

$ touch index.txt
$ echo '01' > serial.txt

Then, perform the following:

$ openssl ca -config openssl-ca.cnf -policy signing_policy -extensions signing_req -out servercert.pem -infiles servercert.csr

You should see similar to the following:

Using configuration from openssl-ca.cnf
Check that the request matches the signature
Signature ok
The Subject's Distinguished Name is as follows
countryName           :PRINTABLE:'US'
stateOrProvinceName   :ASN.1 12:'MD'
localityName          :ASN.1 12:'Baltimore'
commonName            :ASN.1 12:'Test CA'
emailAddress          :IA5STRING:'[email protected]'

After the command executes, you will have a freshly minted server certificate in servercert.pem. The private key was created earlier and is available in serverkey.pem.

Finally, you can inspect your freshly minted certificate with the following:

$ openssl x509 -in servercert.pem -text -noout

Earlier, you added the following to CA_default: copy_extensions = copy. This copies extension provided by the person making the request.

If you omit copy_extensions = copy, then your server certificate will lack the Subject Alternate Names (SANs) like www.example.com and mail.example.com.

If you use copy_extensions = copy, but don't look over the request, then the requester might be able to trick you into signing something like a subordinate root (rather than a server or user certificate). Which means he/she will be able to mint certificates that chain back to your trusted root. Be sure to verify the request with openssl req -verify before signing.

If you omit unique_subject or set it to yes, then you will only be allowed to create one certificate under the subject's distinguished name.

unique_subject = yes            # Set to 'no' to allow creation of
                                # several ctificates with same subject.

Trying to create a second certificate while experimenting will result in the following when signing your server's certificate with the CA's private key:

Sign the certificate? [y/n]:Y

So unique_subject = no is perfect for testing.

If you want to ensure the Organizational Name is consistent between self-signed CAs, Subordinate CA and End-Entity certificates, then add the following to your CA configuration files:

[ policy_match ]
organizationName = match

If you want to allow the Organizational Name to change, then use:

[ policy_match ]
organizationName = supplied

There are other rules concerning the handling of DNS names in X.509/PKIX certificates. Refer to these documents for the rules:

• RFC 5280, Internet X.509 Public Key Infrastructure Certificate and Certificate Revocation List (CRL) Profile
• RFC 6125, Representation and Verification of Domain-Based Application Service Identity within Internet Public Key Infrastructure Using X.509 (PKIX) Certificates in the Context of Transport Layer Security (TLS)
• RFC 6797, Appendix A, HTTP Strict Transport Security (HSTS)
• RFC 7469, Public Key Pinning Extension for HTTP
• CA/Browser Forum Baseline Requirements
• CA/Browser Forum Extended Validation Guidelines

RFC 6797 and RFC 7469 are listed, because they are more restrictive than the other RFCs and CA/B documents. RFC's 6797 and 7469 do not allow an IP address, either.

Python 3.x

from copy import deepcopy

my_dict = {'one': 1, 'two': 2}
new_dict_deepcopy = deepcopy(my_dict)

Without deepcopy, I am unable to remove the hostname dictionary from within my domain dictionary.

Without deepcopy I get the following error:

"RuntimeError: dictionary changed size during iteration"

...when I try to remove the desired element from my dictionary inside of another dictionary.

import socket
import xml.etree.ElementTree as ET
from copy import deepcopy

domain is a dictionary object

def remove_hostname(domain, hostname):
    domain_copy = deepcopy(domain)
    for domains, hosts in domain_copy.items():
        for host, port in hosts.items():
           if host == hostname:
                del domain[domains][host]
    return domain

Example output: [orginal]domains = {'localdomain': {'localhost': {'all': '4000'}}}

[new]domains = {'localdomain': {} }}

So what's going on here is I am iterating over a copy of a dictionary rather than iterating over the dictionary itself. With this method, you are able to remove elements as needed.

Did you try

" or \x22

instead of

\"

?

Edit: I missed the multi-dimensional aspect of this question, so I'm leaving this here in case it helps people compare one-dimensional arrays

It's an old question, but I was having issues with the speed of using .sort() or sortBy(), so I used this instead:

function arraysContainSameStrings(array1: string[], array2: string[]): boolean {
  return (
    array1.length === array2.length &&
    array1.every((str) => array2.includes(str)) &&
    array2.every((str) => array1.includes(str))
  )
}

It was intended to fail fast, and for my purposes works fine.

To get the type, use the builtin type function. With the in operator, you can test if the type is a numpy type by checking if it contains the string numpy;

In [1]: import numpy as np

In [2]: a = np.array([1, 2, 3])

In [3]: type(a)
Out[3]: <type 'numpy.ndarray'>

In [4]: 'numpy' in str(type(a))
Out[4]: True

(This example was run in IPython, by the way. Very handy for interactive use and quick tests.)

See row in ?base::row. This gives the row indices for any matrix-like object.

My problem, it showed an error called "The class Form1 can be designed, but is not the first class in the file. Visual Studio requires that designers use the first class in the file. Move the class code so that it is the first class in the file and try loading the designer again. ". So I moved the Form class to the first one and it worked. :)

In your package explorer, pull down the menu and select "Filters ...". You can adjust what types of files are shown/hidden there.

Looking at my Red Hat Developer Studio (approximately Eclipse 3.2), I see that the top item in the list is ".* resources" and it is excluded by default.

Adding executable permissions, recursively, to all files (not folders) within the current folder with sh extension:

find . -name '*.sh' -type f | xargs chmod +x

* Notice the pipe (|)

Use svn merge:

svn merge -c -[rev num that deleted the file] http://<path to repository>

So an example:

svn merge -c -12345 https://svn.mysite.com/svn/repo/project/trunk
             ^ The negative is important

For TortoiseSVN (I think...)

• Right click in Explorer, go to TortoiseSVN -> Merge...
• Make sure "Merge a range of revisions" is selected, click Next
• In the "Revision range to merge" textbox, specify the revision that removed the file
• Check the "Reverse merge" checkbox, click Next
• Click Merge

That is completely untested, however.

Edited by OP: This works on my version of TortoiseSVN (the old kind without the next button)

• Go to the folder that stuff was delated from
• Right click in Explorer, go to TortoiseSVN -> Merge...
• in the From section enter the revision that did the delete
• in the To section enter the revision before the delete.
• Click "merge"
• commit

The trick is to merge backwards. Kudos to sean.bright for pointing me in the right direction!

Edit: We are using different versions. The method I described worked perfectly with my version of TortoiseSVN.

Also of note is that if there were multiple changes in the commit you are reverse merging, you'll want to revert those other changes once the merge is done before you commit. If you don't, those extra changes will also be reversed.

To execute your program from the command line, you have to call the python interpreter, like this :

C:\Python27>python hello.py 1 1

If you code resides in another directory, you will have to set the python binary path in your PATH environment variable, to be able to run it, too. You can find detailed instructions here.

If supported by your browser, you may use CSS3 :read-only selector:

input[type="text"]:read-only {
    cursor: normal;
    background-color: #f8f8f8;
    color: #999;
}

Well, one classic example is where you wanted to get a list of employees and their immediate managers:

select e.employee as employee, b.employee as boss
from emptable e, emptable b
where e.manager_id = b.empolyee_id
order by 1

It's basically used where there is any relationship between rows stored in the same table.

• employees.
• multi-level marketing.
• machine parts.

And so on...

Ok so here's how I figured this out. It all has to do with CORS policy. Before the POST request, Chrome was doing a preflight OPTIONS request, which should be handled and acknowledged by the server prior to the actual request. Now this is really not what I wanted for such a simple server. Hence, resetting the headers client side prevents the preflight:

app.config(function ($httpProvider) {
  $httpProvider.defaults.headers.common = {};
  $httpProvider.defaults.headers.post = {};
  $httpProvider.defaults.headers.put = {};
  $httpProvider.defaults.headers.patch = {};
});

The browser will now send a POST directly. Hope this helps a lot of folks out there... My real problem was not understanding CORS enough.

Kudos to this answer for showing me the way.

in IE you can get the event object by window.event in other browsers with no 'use strict' directive, it is possible to get by arguments.callee.caller.arguments[0].

function myFunc(p1, p2, p3) {
    var evt = window.event || arguments.callee.caller.arguments[0];
}

This would be a get/set in C# using the smallest amount of code possible. You get auto-implemented properties in C# 3.0+.

public class Contact
{
   public string Name { get; set; }
}

You need to do this in transaction to ensure two simultaneous clients won't insert same fieldValue twice:

SET TRANSACTION ISOLATION LEVEL SERIALIZABLE
BEGIN TRANSACTION
    DECLARE @id AS INT
    SELECT @id = tableId FROM table WHERE fieldValue=@newValue
    IF @id IS NULL
    BEGIN
       INSERT INTO table (fieldValue) VALUES (@newValue)
       SELECT @id = SCOPE_IDENTITY()
    END
    SELECT @id
COMMIT TRANSACTION

you can also use Double-checked locking to reduce locking overhead

DECLARE @id AS INT
SELECT @id = tableID FROM table (NOLOCK) WHERE fieldValue=@newValue
IF @id IS NULL
BEGIN
    SET TRANSACTION ISOLATION LEVEL SERIALIZABLE
    BEGIN TRANSACTION
        SELECT @id = tableID FROM table WHERE fieldValue=@newValue
        IF @id IS NULL
        BEGIN
           INSERT INTO table (fieldValue) VALUES (@newValue)
           SELECT @id = SCOPE_IDENTITY()
        END
    COMMIT TRANSACTION
END
SELECT @id

As for why ISOLATION LEVEL SERIALIZABLE is necessary, when you are inside a serializable transaction, the first SELECT that hits the table creates a range lock covering the place where the record should be, so nobody else can insert the same record until this transaction ends.

Without ISOLATION LEVEL SERIALIZABLE, the default isolation level (READ COMMITTED) would not lock the table at read time, so between SELECT and UPDATE, somebody would still be able to insert. Transactions with READ COMMITTED isolation level do not cause SELECT to lock. Transactions with REPEATABLE READS lock the record (if found) but not the gap.

I'm going to post an answer because some of the existing answers are close but have one of:

• a smaller character space than you wanted so that either brute-forcing is easier or the password must be longer for the same entropy
• a RNG that isn't considered cryptographically secure
• a requirement for some 3rd party library and I thought it might be interesting to show what it might take to do it yourself

This answer will circumvent the count/strlen issue as the security of the generated password, at least IMHO, transcends how you're getting there. I'm also going to assume PHP > 5.3.0.

Let's break the problem down into the constituent parts which are:

1. use some secure source of randomness to get random data
2. use that data and represent it as some printable string

For the first part, PHP > 5.3.0 provides the function openssl_random_pseudo_bytes. Note that whilst most systems use a cryptographically strong algorithm, you have to check so we'll use a wrapper:

/**
 * @param int $length
 */
function strong_random_bytes($length)
{
    $strong = false; // Flag for whether a strong algorithm was used
    $bytes = openssl_random_pseudo_bytes($length, $strong);

    if ( ! $strong)
    {
        // System did not use a cryptographically strong algorithm 
        throw new Exception('Strong algorithm not available for PRNG.');
    }        

    return $bytes;
}

For the second part, we'll use base64_encode since it takes a byte string and will produce a series of characters that have an alphabet very close to the one specified in the original question. If we didn't mind having +, / and = characters appear in the final string and we want a result at least $n characters long, we could simply use:

base64_encode(strong_random_bytes(intval(ceil($n * 3 / 4))));

The 3/4 factor is due to the fact that base64 encoding results in a string that has a length at least a third bigger than the byte string. The result will be exact for $n being a multiple of 4 and up to 3 characters longer otherwise. Since the extra characters are predominantly the padding character =, if we for some reason had a constraint that the password be an exact length, then we can truncate it to the length we want. This is especially because for a given $n, all passwords would end with the same number of these, so that an attacker who had access to a result password, would have up to 2 less characters to guess.

For extra credit, if we wanted to meet the exact spec as in the OP's question then we would have to do a little bit more work. I'm going to forgo the base conversion approach here and go with a quick and dirty one. Both need to generate more randomness than will be used in the result anyway because of the 62 entry long alphabet.

For the extra characters in the result, we can simply discard them from the resulting string. If we start off with 8 bytes in our byte-string, then up to about 25% of the base64 characters would be these "undesirable" characters, so that simply discarding these characters results in a string no shorter than the OP wanted. Then we can simply truncate it to get down to the exact length:

$dirty_pass = base64_encode(strong_random_bytes(8)));
$pass = substr(str_replace(['/', '+', '='], ['', '', ''], $dirty_pass, 0, 8);

If you generate longer passwords, the padding character = forms a smaller and smaller proportion of the intermediate result so that you can implement a leaner approach, if draining the entropy pool used for the PRNG is a concern.

After adding the reference, I had to use

Dim fso As New Scripting.FileSystemObject

Note that this may happen even if the file path is correct due to s3's eventual consistency model. Basically, there may be some latency in being able to read an object after it's written. See this documentation for more information.

Common Table Expressions let you define what are essentially views that last only within the scope of your select, insert, update and delete statements. Depending on what you need to do they can be terribly useful.

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

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

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

Live Example:

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

I think this is the most reliable way to get the desktop path which isn't always the same as the username.

MsgBox CreateObject("WScript.Shell").specialfolders("Desktop")

Now here's a twist:

You should place all fonts in app/assets/fonts/ as they WILL get precompiled in staging and production by default—they will get precompiled when pushed to heroku.

Font files placed in vendor/assets will NOT be precompiled on staging or production by default — they will fail on heroku. Source!

— @plapier, thoughtbot/bourbon

I strongly believe that putting vendor fonts into vendor/assets/fonts makes a lot more sense than putting them into app/assets/fonts. With these 2 lines of extra configuration this has worked well for me (on Rails 4):

app.config.assets.paths << Rails.root.join('vendor', 'assets', 'fonts')  
app.config.assets.precompile << /\.(?:svg|eot|woff|ttf)$/

— @jhilden, thoughtbot/bourbon

I've also tested it on rails 4.0.0. Actually the last one line is enough to safely precompile fonts from vendor folder. Took a couple of hours to figure it out. Hope it helped someone.

Dan, it's just you're accessing the protected field instead of properties.

See for example this line in your Main(...):

myClub.distance = Console.ReadLine();

myClub.distance is the protected field, while you wanted to set the property mydistance.

I'm just giving you some hint, I'm not going to correct your code, since this is homework! ;)

The above answers are right, but you have to make sure you input right URL.

You have to go to: https://developers.facebook.com/apps

1. Select your app
2. Click settings
3. Enter contact email (for publishing)
4. Click on +add platform
5. Add your platform (probably WEB)
6. Enter site URL

You have two choices to enter: http://www.example.com or http://example.com

Your app will work only with one of them. In order to make sure your visitors will use your desired url, use .htaccess on your domain.

Here's good tutorial on that: http://eppand.com/redirect-www-to-non-www-with-htaccess-file/

Enjoy!

For those running JPA in Spring, from version 3.1 onwards, you can set packagesToScan property under LocalContainerEntityManagerFactoryBean and get rid of persistence.xml altogether.

Here's the low-down

a similar solution using jquery would be:

$(window).scroll(function () {
  $('.header').css('position','fixed');
});

This turns the header into a fixed position element immediately on scroll

It is very simple :

1. Go to MySQL workbench and lookup for Database > Manage Connections
2. you will see a list of connections. Click on the connection you wish to connect to.
3. You will see a tabs around connection, remote management, system profile. Click on connection tab.
4. your url is jdbc:mysql://<hostname>:<port>/<dbname>?prop1 etc. where <hostname> and <port> are given in the connection tab.It will mostly be localhost : 3306. <dbname> will be found under System Profile tab in Windows Service Name. Default will mostly be MySQL5<x> where x is the version number eg. 56 for MySQL5.6 and 55 for MySQL5.5 etc.You can specify ur own Windows Service name to connect too.
5. Construct the url accordingly and set the url to connect.

If you want to avoid having to use CTRL+SHIFT+B and instead want this to occur any time you save a file, you can bind the command to the same short-cut as the save action:

[
    {
        "key": "ctrl+s",          
        "command": "workbench.action.tasks.build" 
    }
]

This goes in your keybindings.json - (head to this using File -> Preferences -> Keyboard Shortcuts).

the data you have entered a table(tbldomare) aren't match a data you have assigned primary key table. write between tbldomare and add this word (with nocheck) then execute your code.

for example you entered a table tbldomar this data

INSERT INTO tblDomare (PersNR,fNamn,eNamn,Erfarenhet)
Values (6811034679,'Bengt','Carlberg',10);

and you assigned a foreign key table to accept only 1,2,3.

you have two solutions one is delete the data you have entered a table then execute the code. another is write this word (with nocheck) put it between your table name and add like this

ALTER TABLE  tblDomare with nocheck
ADD FOREIGN KEY (PersNR)
REFERENCES tblBana(BanNR);

radioSexGroup=(RadioGroup)findViewById(R.id.radioGroup);

  btnDisplay=(Button)findViewById(R.id.button);

  btnDisplay.setOnClickListener(new View.OnClickListener() {
     @Override
     public void onClick(View v) {
        int selectedId=radioSexGroup.getCheckedRadioButtonId();
        radioSexButton=(RadioButton)findViewById(selectedId);
        Toast.makeText(MainActivity.this,radioSexButton.getText(),Toast.LENGTH_SHORT).show();
     }
  });

No you cannot do that in Java. you can however write a method as follows:

boolean isContains(int i, int ... numbers) {
    // code to check if i is one of the numbers
    for (int n : numbers) {
        if (i == n) return true;
    }
    return false;
}

I notice others have given the non-lambda syntax so just to have this complete I'll put in the lambda syntax equivalent:

Non-lambda (as per James's post):

var name = from i in DataContext.MyTable
           where i.ID == 0
           select i.Name

Equivalent lambda syntax:

var name = DataContext.MyTable.Where(i => i.ID == 0)
                              .Select(i => new { Name = i.Name });

There's not really much practical difference, just personal opinion on which you prefer.

HTTP status codes say something about the HTTP protocol. HTTP 200 means transmission is OK on the HTTP level (i.e request was technically OK and server was able to respond properly). See this wiki page for a list of all codes and their meaning.

HTTP 200 has nothing to do with success or failure of your "business code". In your example the HTTP 200 is an acceptable status to indicate that your "business code error message" was successfully transferred, provided that no technical issues prevented the business logic to run properly.

Alternatively you could let your server respond with HTTP 5xx if technical or unrecoverable problems happened on the server. Or HTTP 4xx if the incoming request had issues (e.g. wrong parameters, unexpected HTTP method...) Again, these all indicate technical errors, whereas HTTP 200 indicates NO technical errors, but makes no guarantee about business logic errors.

To summarize: YES it is valid to send error messages (for non-technical issues) in your http response together with HTTP status 200. Whether this applies to your case is up to you. If for instance the client is asking for a file that isn't there, that would be more like a 404. If there is a misconfiguration on the server that might be a 500. If client asks for a seat on a plane that is booked full, that would be 200 and your "implementation" will dictate how to recognise/handle this (e.g. JSON block with a { "booking","failed" })

The problem still not resolved after remove the '.', then it start points the error to my folder. As i added this folder first time then i restarted the PyCharm and it automatically resolved the issue

For anyone coming to this latterly, I was having this problem over a Windows network, and offer an additional thing to check:

Python script connecting would work from commandline on my (linux) machine, but some users had problems connecting - that it worked from CLI suggested the DSN and credentials were right. The issue for us was that the group security policy required the ODBC credentials to be set on every machine. Once we added that (for some reason, the user had three of the four ODBC credentials they needed for our various systems), they were able to connect.

You can of course do that at group level, but as it was a simple omission on the part of one machine, I did it in Control Panel > ODBC Drivers > New

There is a lot of good advice on memory optimizations.

Some of the tips are:

• Use nested NSAutoReleasePools to make sure your memory usage does not spike.
• Use CGImageSource when creating thumbnails from large images.
• Respond to low memory warnings.

Google is full of information on this. As Hans Passant said, Form controls are built in to Excel whereas ActiveX controls are loaded separately.

Generally you'll use Forms controls, they're simpler. ActiveX controls allow for more flexible design and should be used when the job just can't be done with a basic Forms control.

Many user's computers by default won't trust ActiveX, and it will be disabled; this sometimes needs to be manually added to the trust center. ActiveX is a microsoft-based technology and, as far as I'm aware, is not supported on the Mac. This is something you'll have to also consider, should you (or anyone you provide a workbook to) decide to use it on a Mac.

The original code you suggest is the best way.

Matlab is extremely good at vectorized operations such as this, at least for large vectors.

The built-in norm function is very fast. Here are some timing results:

V = rand(10000000,1);
% Run once
tic; V1=V/norm(V); toc           % result:  0.228273s
tic; V2=V/sqrt(sum(V.*V)); toc   % result:  0.325161s
tic; V1=V/norm(V); toc           % result:  0.218892s

V1 is calculated a second time here just to make sure there are no important cache penalties on the first call.

Timing information here was produced with R2008a x64 on Windows.

EDIT:

Revised answer based on gnovice's suggestions (see comments). Matrix math (barely) wins:

clc; clear all;
V = rand(1024*1024*32,1);
N = 10;
tic; for i=1:N, V1 = V/norm(V);         end; toc % 6.3 s
tic; for i=1:N, V2 = V/sqrt(sum(V.*V)); end; toc % 9.3 s
tic; for i=1:N, V3 = V/sqrt(V'*V);      end; toc % 6.2 s ***
tic; for i=1:N, V4 = V/sqrt(sum(V.^2)); end; toc % 9.2 s
tic; for i=1:N, V1=V/norm(V);           end; toc % 6.4 s

IMHO, the difference between "norm(V)" and "sqrt(V'*V)" is small enough that for most programs, it's best to go with the one that's more clear. To me, "norm(V)" is clearer and easier to read, but "sqrt(V'*V)" is still idiomatic in Matlab.

You must do something like this

SELECT onDay, id, 
sum(pxLow)/count(*),sum(pxLow),count(`*`),
CONCAT(YEAR(onDay),"-",MONTH(onDay)) as sdate 
FROM ... where stockParent_id =16120 group by sdate order by onDay

For future people struggling with a similar problem, the situation is that the compiler simply cannot find the type you are using (even if your Intelisense can find it).

This can be caused in many ways:

• You forgot to #include the header that defines it.
• Your inclusion guards (#ifndef BLAH_H) are defective (your #ifndef BLAH_H doesn't match your #define BALH_H due to a typo or copy+paste mistake).
• Your inclusion guards are accidentally used twice (two separate files both using #define MYHEADER_H, even if they are in separate directories)
• You forgot that you are using a template (eg. new Vector() should be new Vector<int>())
• The compiler is thinking you meant one scope when really you meant another (For example, if you have NamespaceA::NamespaceB, AND a <global scope>::NamespaceB, if you are already within NamespaceA, it'll look in NamespaceA::NamespaceB and not bother checking <global scope>::NamespaceB) unless you explicitly access it.
• You have a name clash (two entities with the same name, such as a class and an enum member).

To explicitly access something in the global namespace, prefix it with ::, as if the global namespace is a namespace with no name (e.g. ::MyType or ::MyNamespace::MyType).

This will loop through only once.

Item biggest = items.Aggregate((i1,i2) => i1.ID > i2.ID ? i1 : i2);

Thanks Nick - Here's the proof

class Program
{
    static void Main(string[] args)
    {
        IEnumerable<Item> items1 = new List<Item>()
        {
            new Item(){ ClientID = 1, ID = 1},
            new Item(){ ClientID = 2, ID = 2},
            new Item(){ ClientID = 3, ID = 3},
            new Item(){ ClientID = 4, ID = 4},
        };
        Item biggest1 = items1.Aggregate((i1, i2) => i1.ID > i2.ID ? i1 : i2);

        Console.WriteLine(biggest1.ID);
        Console.ReadKey();
    }


}

public class Item
{
    public int ClientID { get; set; }
    public int ID { get; set; }
}  

Rearrange the list and get the same result

I'm running Microsoft Windows 10 Pro, Version 10.0.17763 Build 17763, and I see my .ssh folder easily at C:\Users\jrosario\.ssh without having to edit permissions or anything (though in File Explorer, I did select "Show hidden files, folders and drives"):

The keys are stored in a text file named known_hosts, which looks roughly like this:

Try this working fine....

SELECT computer.NAME, application.NAME,software.Version FROM computer LEFT JOIN software_computer ON(computer.ID = software_computer.ComputerID)
 LEFT JOIN software ON(software_computer.SoftwareID = Software.ID) LEFT JOIN application ON(application.ID = software.ApplicationID) 
 where computer.id = 1 group by application.NAME UNION SELECT computer.NAME, application.NAME,
 NULL as Version FROM computer, application WHERE application.ID not in ( SELECT s.applicationId FROM software_computer sc LEFT JOIN software s 
 on s.ID = sc.SoftwareId WHERE sc.ComputerId = 1 ) 
 AND computer.id = 1 

They don't do the same thing. The first one works if obj is of type ClassA or of some subclass of ClassA. The second one will only match objects of type ClassA. The second one will be faster since it doesn't have to check the class hierarchy.

For those who want to know the reason, but don't want to read the article referenced in is vs typeof.

I think it would be interesting to write both of them in a way that only by switching some lines of code would give you one algorithm or the other, so that you will see that your dillema is not so strong as it seems to be at first.

I personally like the interpretation of BFS as flooding a landscape: the low altitude areas will be flooded first, and only then the high altitude areas would follow. If you imagine the landscape altitudes as isolines as we see in geography books, its easy to see that BFS fills all area under the same isoline at the same time, just as this would be with physics. Thus, interpreting altitudes as distance or scaled cost gives a pretty intuitive idea of the algorithm.

With this in mind, you can easily adapt the idea behind breadth first search to find the minimum spanning tree easily, shortest path, and also many other minimization algorithms.

I didnt see any intuitive interpretation of DFS yet (only the standard one about the maze, but it isnt as powerful as the BFS one and flooding), so for me it seems that BFS seems to correlate better with physical phenomena as described above, while DFS correlates better with choices dillema on rational systems (ie people or computers deciding which move to make on a chess game or going out of a maze).

So, for me the difference between lies on which natural phenomenon best matches their propagation model (transversing) in real life.

The end of the variable name is usually signified by a space or newline. But what if we don't want a space or newline after printing the variable value? The curly braces tell the shell interpreter where the end of the variable name is.

Classic Example 1) - shell variable without trailing whitespace

TIME=10

# WRONG: no such variable called 'TIMEsecs'
echo "Time taken = $TIMEsecs"

# What we want is $TIME followed by "secs" with no whitespace between the two.
echo "Time taken = ${TIME}secs"

Example 2) Java classpath with versioned jars

# WRONG - no such variable LATESTVERSION_src
CLASSPATH=hibernate-$LATESTVERSION_src.zip:hibernate_$LATEST_VERSION.jar

# RIGHT
CLASSPATH=hibernate-${LATESTVERSION}_src.zip:hibernate_$LATEST_VERSION.jar

(Fred's answer already states this but his example is a bit too abstract)

I have another possibility. This is of course a "newer" technique, but for my projects works sufficient.

It only works if you need one or two borders. I've never done it with 4 borders... and to be honest, I don't know the answer for that yet.

.your-item {
  position: relative;
}

.your-item:after {
  content: '';
  height: 100%; //You can change this if you want smaller/bigger borders
  width: 1px;

  position: absolute;
  right: 0;
  top: 0; // If you want to set a smaller height and center it, change this value

  background-color: #000000; // The color of your border
}

I hope this helps you too, as for me, this is an easy workaround.

Escape sequences must be interpreted by SOMETHING to be converted to color. The standard CMD.EXE used by java when started from the command line, doesn't support this so therefore Java does not.

I found the above when looking for downloading from FTP with username and address in URL. Users supply information and then make the calls.

This was helpful because our organization has Kaspersky AV which blocks active FTP.exe, but not web connections. We were unable to develop in house with ftp.exe and this was our solution. Hope this helps other looking for info!

On macOS Sierra (10.12) :

1. Run the following command to see if CLT is installed:

   xcode-select -p
   

   this will return the path to the tool if CLT is already installed. Something like this -

   /Applications/Xcode.app/Contents/Developer
   

2. Run the following command to see the version of CLT:

   pkgutil --pkg-info=com.apple.pkg.CLTools_Executables
   

   this will return version info, output will be something like this -

   package-id: com.apple.pkg.CLTools_Executables
   version: 8.2.0.0.1.1480973914
   volume: /
   location: /
   install-time: 1486372375
   

The registry path for Visual Studio 2008 is the same, but with 9.0 as the version number:

HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\9.0\Text Editor

Maybe, you can use the array syntax of javascript :

var finalObj =[json1 , json2]

If you do not want to define a separate class for nested json , Defining nested json object as JsonNode should work ,for example :

{"id":2,"socket":"0c317829-69bf-43d6-b598-7c0c550635bb","type":"getDashboard","data":{"workstationUuid":"ddec1caa-a97f-4922-833f-632da07ffc11"},"reply":true}

@JsonProperty("data")
    private JsonNode data;

Here is the little hack to overcome all the struggles you have for video autoplay in a website:

1. Check video is playing or not.
2. Trigger video play on event like body click or touch.

Note: Some browsers don't let videos to autoplay unless the user interacts with the device.

So scripts to check whether video is playing is:

Object.defineProperty(HTMLMediaElement.prototype, 'playing', {
get: function () {
    return !!(this.currentTime > 0 && !this.paused && !this.ended && this.readyState > 2);
}});

And then you can simply autoplay the video by attaching event listeners to the body:

$('body').on('click touchstart', function () {
        const videoElement = document.getElementById('home_video');
        if (videoElement.playing) {
            // video is already playing so do nothing
        }
        else {
            // video is not playing
            // so play video now
            videoElement.play();
        }
});

Note: autoplay attribute is very basic which needs to be added to the video tag already other than these scripts.

You can see the working example with code here at this link:

After copying my local repository and working copy to another folder (on Windows by the way), I had four files that kept showing up as changed and tried every suggestion listed in the other answers. In the end what fixed it for me was deleting the local branch and downloading it again from the remote. In my case I guess it had something to do with copying a local repository rather than cloning.

I also came across this problem. In my case, I didn't know the type of the IEnumerable. So the answers given above wont work. However, I solved it like this:

public static DataTable CreateDataTable(IEnumerable source)
    {
        var table = new DataTable();
        int index = 0;
        var properties = new List<PropertyInfo>();
        foreach (var obj in source)
        {
            if (index == 0)
            {
                foreach (var property in obj.GetType().GetProperties())
                {
                    if (Nullable.GetUnderlyingType(property.PropertyType) != null)
                    {
                        continue;
                    }
                    properties.Add(property);
                    table.Columns.Add(new DataColumn(property.Name, property.PropertyType));
                }
            }
            object[] values = new object[properties.Count];
            for (int i = 0; i < properties.Count; i++)
            {
                values[i] = properties[i].GetValue(obj);
            }
            table.Rows.Add(values);
            index++;
        }
        return table;
    }

Keep in mind that using this method, requires at least one item in the IEnumerable. If that's not the case, the DataTable wont create any columns.

If you're using at least Java 8, see my other answer.

If you're already using Google Guava, see Sean Patrick Floyd's answer.

If you're stuck at Java 7 and don't want to include Google Guava, you can write your own (read-only) Iterables.concat() using no more than Iterable and Iterator:

Constant number

public static <E> Iterable<E> concat(final Iterable<? extends E> iterable1,
                                     final Iterable<? extends E> iterable2) {
    return new Iterable<E>() {
        @Override
        public Iterator<E> iterator() {
            return new Iterator<E>() {
                final Iterator<? extends E> iterator1 = iterable1.iterator();
                final Iterator<? extends E> iterator2 = iterable2.iterator();

                @Override
                public boolean hasNext() {
                    return iterator1.hasNext() || iterator2.hasNext();
                }

                @Override
                public E next() {
                    return iterator1.hasNext() ? iterator1.next() : iterator2.next();
                }
            };
        }
    };
}

Variable number

@SafeVarargs
public static <E> Iterable<E> concat(final Iterable<? extends E>... iterables) {
    return concat(Arrays.asList(iterables));
}

public static <E> Iterable<E> concat(final Iterable<Iterable<? extends E>> iterables) {
    return new Iterable<E>() {
        final Iterator<Iterable<? extends E>> iterablesIterator = iterables.iterator();

        @Override
        public Iterator<E> iterator() {
            return !iterablesIterator.hasNext() ? Collections.emptyIterator()
                                                : new Iterator<E>() {
                Iterator<? extends E> iterableIterator = nextIterator();

                @Override
                public boolean hasNext() {
                    return iterableIterator.hasNext();
                }

                @Override
                public E next() {
                    final E next = iterableIterator.next();
                    findNext();
                    return next;
                }

                Iterator<? extends E> nextIterator() {
                    return iterablesIterator.next().iterator();
                }

                Iterator<E> findNext() {
                    while (!iterableIterator.hasNext()) {
                        if (!iterablesIterator.hasNext()) {
                            break;
                        }
                        iterableIterator = nextIterator();
                    }
                    return this;
                }
            }.findNext();
        }
    };
}

This is working Oracle example but it should work in MySQL too.

You are missing smth - see IN after END Replace 'IN' with '=' sign for a single value.

SELECT empno, ename, job
  FROM scott.emp
 WHERE (CASE WHEN job = 'MANAGER' THEN '1'  
         WHEN job = 'CLERK'   THEN '2' 
         ELSE '0'  END) IN (1, 2)

There is no error when I use your code,

but I am calling the hasLetter method like this:

hasLetter("a",words);

My try is combined solution.

string = string.replace(',', '.').replace(/[^\d\.]/g, "").replace(/\./, "x").replace(/\./g, "").replace(/x/, ".");
string = Math.round( parseFloat(string) * 100) / 100;

First line solution from here: regex replacing multiple periods in floating number . It replaces comma "," with dot "." ; Replaces first comma with x; Removes all dots and replaces x back to dot.

Second line cleans numbers after dot.

A simple Swift 2.0 approach to making a HTTP GET request

The HTTP request is asynchronous so you need a way to get the returned value from the HTTP Request. This approach uses Notifiers and is spread over two classes.

The example is to check the username and password for an identifier token using the website http://www.example.com/handler.php?do=CheckUserJson&json= That is the file is called handler.php and has a switch statement on the do parameter to get a RESTful approach.

In the viewDidLoad we setup the NotifierObserver, set up the json and make the call to the getHTTPRequest function. It will return to the function checkedUsernameAndPassword with the returned parameter from the http request.

override func viewDidLoad() {
    super.viewDidLoad()
    // setup the Notification observer to catch the result of check username and password
    NSNotificationCenter.defaultCenter().addObserver(self, selector: "checkedUsernameAndPassword:", name: CHECK_USERNAME_AND_PASSWORD, object: nil)        
    let username = GlobalVariables.USER_NAME
    let password = GlobalVariables.PASSWORD
    // check username and password
    if let jsonString = Utility.checkUsernameAndPasswordJson(username, password:password){
        print("json string returned = \(jsonString)")
        let url = CHECKUSERJSON+jsonString
        // CHECKUSERJSON = http://www.example.com/handler.php?do=CheckUserJson&json=
        // jsonString = {\"username\":\"demo\",\"password\":\"demo\"}"
        // the php script handles a json request and returns a string identifier           
        Utility.getHTTPRequest(url,notifierId: CHECK_USERNAME_AND_PASSWORD)
        // the returned identifier is sent to the checkedUsernaeAndPassword function when it becomes availabel.
    }
}

There are two static functions in Utility.swift first to encode the json and then to do the HTTP call.

    static func checkUsernameAndPasswordJson(username: String, password: String) -> String?{
    let para:NSMutableDictionary = NSMutableDictionary()
        para.setValue("demo", forKey: "username")
        para.setValue("demo", forKey: "password")
    let jsonData: NSData
    do{
        jsonData = try NSJSONSerialization.dataWithJSONObject(para, options: NSJSONWritingOptions())
        let jsonString = NSString(data: jsonData, encoding: NSUTF8StringEncoding) as! String
        return jsonString
    } catch _ {
        print ("UH OOO")
        return nil
    }
}

and the Http request

    static func getHTTPRequest (url:String , notifierId: String) -> Void{
    let urlString = url
    let config = NSURLSessionConfiguration.defaultSessionConfiguration()
    let session = NSURLSession(configuration: config, delegate: nil, delegateQueue: nil)
    let safeURL = urlString.stringByAddingPercentEncodingWithAllowedCharacters(NSCharacterSet.URLQueryAllowedCharacterSet())!
    if let url = NSURL(string: safeURL){
        let request  = NSMutableURLRequest(URL: url)
        request.HTTPMethod = "GET"
        request.timeoutInterval = 60
        let taskData = session.dataTaskWithRequest(request, completionHandler: {
            (data:NSData?, response:NSURLResponse?, error:NSError?) -> Void in
            if (data != nil) {
                let result = NSString(data: data! , encoding: NSUTF8StringEncoding)
                sendNotification (notifierId, message: String(result), num: 0)
            }else{
                  sendNotification (notifierId, message: String(UTF8String: nil), num: -1)                    }
        })
    taskData.resume()
    }else{
        print("bad urlString = \(urlString)")
    }
}

The sendNotification function completes the circle. Notice that in teh Observer there is a ":" at the end of the selector string. This allows the notification to carry a payload in userInfo. I give this a String and an Int.

    static func sendNotification (key: String, message:String?, num: Int?){
    NSNotificationCenter.defaultCenter().postNotificationName(
        key,
        object: nil,
        userInfo:   (["message": message!,
                      "num": "\(num!)"])
    )
}

Note that using HTTP is oldFashioned, prefer HTTPS see How do I load an HTTP URL with App Transport Security enabled in iOS 9?

The currently accepted answer has several issues. This post explains them, and offers a more robust solution. The solution suggested in that answer previously had:

var encodedStr = rawStr.replace(/[\u00A0-\u9999<>\&]/gim, function(i) {
  return '&#' + i.charCodeAt(0) + ';';
});

The i flag is redundant since no Unicode symbol in the range from U+00A0 to U+9999 has an uppercase/lowercase variant that is outside of that same range.

The m flag is redundant because ^ or $ are not used in the regular expression.

Why the range U+00A0 to U+9999? It seems arbitrary.

Anyway, for a solution that correctly encodes all except safe & printable ASCII symbols in the input (including astral symbols!), and implements all named character references (not just those in HTML4), use the he library (disclaimer: This library is mine). From its README:

he (for “HTML entities”) is a robust HTML entity encoder/decoder written in JavaScript. It supports all standardized named character references as per HTML, handles ambiguous ampersands and other edge cases just like a browser would, has an extensive test suite, and — contrary to many other JavaScript solutions — he handles astral Unicode symbols just fine. An online demo is available.

Also see this relevant Stack Overflow answer.

What does return; mean?

return; really means it returns nothing void. That's it.

why return; or other codes can write below the statement of System.exit(0);

It is allowed since compiler doesn't know calling System.exit(0) will terminate the JVM. The compiler will just give a warning - unnecessary return statement

The correct way of extracting miliseconds from a timestamp value on PostgreSQL accordingly to current documentation is:

SELECT date_part('milliseconds', current_timestamp);

--OR

SELECT EXTRACT(MILLISECONDS FROM current_timestamp);

with returns: The seconds field, including fractional parts, multiplied by 1000. Note that this includes full seconds.

To further work with array of maps, the followings could help:

@RequestMapping(value = "/process", method = RequestMethod.POST, headers = "Accept=application/json")
public void setLead(@RequestBody Collection<? extends Map<String, Object>> payload) throws Exception {

  List<Map<String,Object>> maps = new ArrayList<Map<String,Object>>();
  maps.addAll(payload);

}

Read a file as a string full version (handling exceptions, using UTF-8, handling new line):

// Calling:
/* 
    Context context = getApplicationContext();
    String filename = "log.txt";
    String str = read_file(context, filename);
*/  
public String read_file(Context context, String filename) {
        try {
            FileInputStream fis = context.openFileInput(filename);
            InputStreamReader isr = new InputStreamReader(fis, "UTF-8");
            BufferedReader bufferedReader = new BufferedReader(isr);
            StringBuilder sb = new StringBuilder();
            String line;
            while ((line = bufferedReader.readLine()) != null) {
                sb.append(line).append("\n");
            }
            return sb.toString();
        } catch (FileNotFoundException e) {
            return "";
        } catch (UnsupportedEncodingException e) {
            return "";
        } catch (IOException e) {
            return "";
        }
    }

Note: you don't need to bother about file path only with file name.

Added MSSQLSERVER full access to the folder, diskadmin and bulkadmin server roles.

In my c# application, when preparing for the bulk insert command,

string strsql = "BULK INSERT PWCR_Contractor_vw_TEST FROM '" + strFileName + "' WITH (FIELDTERMINATOR = ',', ROWTERMINATOR = '\\n')";

And I get this error - Bulk load data conversion error (type mismatch or invalid character for the specified codepage) for row 1, column 8 (STATUS).

I looked at my logfile and found that the terminator becomes ' ' instead of '\n'. The OLE DB provider "BULK" for linked server "(null)" reported an error. The provider did not give any information about the error:

Cannot fetch a row from OLE DB provider "BULK" for linked server "(null)". Query :BULK INSERT PWCR_Contractor_vw_TEST FROM 'G:\NEWSTAGEWWW\CalAtlasToPWCR\Results\parsedRegistration.csv' WITH (FIELDTERMINATOR = ',', **ROWTERMINATOR = ''**)

So I added extra escape to the rowterminator - string strsql = "BULK INSERT PWCR_Contractor_vw_TEST FROM '" + strFileName + "' WITH (FIELDTERMINATOR = ',', ROWTERMINATOR = '\\n')";

And now it inserts successfully.

Debugging PHP with VSCode using the vscode-php-debug extension

VSCode can now support debugging PHP projects through the marketplace extension vscode-php-debug.

This extension uses XDebug in the background, and allows you to use breakpoints, watches, stack traces and the like:

Installation is straightforward from within VSCode: Summon the command line with F1 and then type ext install php-debug

Before FontAwesome 5:

The standard declarations just contain .fa-rotate-90, .fa-rotate-180 and .fa-rotate-270. However you can easily create your own:

.fa-rotate-45 {
    -webkit-transform: rotate(45deg);
    -moz-transform: rotate(45deg);
    -ms-transform: rotate(45deg);
    -o-transform: rotate(45deg);
    transform: rotate(45deg);
}

With FontAwesome 5:

You can use what’s so called “Power Transforms”. Example:

<i class="fas fa-snowman" data-fa-transform="rotate-90"></i>
<i class="fas fa-snowman" data-fa-transform="rotate-180"></i>
<i class="fas fa-snowman" data-fa-transform="rotate-270"></i>
<i class="fas fa-snowman" data-fa-transform="rotate-30"></i>
<i class="fas fa-snowman" data-fa-transform="rotate--30"></i>

You need to add the data-fa-transform attribute with the value of rotate- and your desired rotation in degrees.

List Vs Set

1) Set does not allow duplicates. List allows duplicate. Based on the implementation of Set, It also maintains the insertion Order .

eg : LinkedHashSet. It maintains the insertion order.Please refer click here

2) contains method. By nature of the Set it will give better performance to access. Best case its o(1). But List has performance issue to invoke contains.

The easiest solution today is to used Apache common io :

http://commons.apache.org/proper/commons-io/javadocs/api-release/org/apache/commons/io/FileUtils.html#readFileToByteArray(java.io.File)

byte bytes[] = FileUtils.readFileToByteArray(photoFile)

The only drawback is to add this dependency in your build.gradle app :

implementation 'commons-io:commons-io:2.5'

+ 1562 Methods count

mysql --help | grep /my.cnf | xargs ls

will tell you where my.cnf is located on Mac/Linux

ls: cannot access '/etc/my.cnf': No such file or directory
ls: cannot access '~/.my.cnf': No such file or directory
 /etc/mysql/my.cnf

In this case, it is in /etc/mysql/my.cnf

ls: /etc/my.cnf: No such file or directory
ls: /etc/mysql/my.cnf: No such file or directory
ls: ~/.my.cnf: No such file or directory
/usr/local/etc/my.cnf

In this case, it is in /usr/local/etc/my.cnf

Did you try a UNC share?

\\server\share\foo.exe

If you're using SQL Server 2008, there's a new featured called a User Defined Table Type. Here is an example of how to use it:

Create your User Defined Table Type:

CREATE TYPE [dbo].[StringList] AS TABLE(
    [Item] [NVARCHAR](MAX) NULL
);

Next you need to use it properly in your stored procedure:

CREATE PROCEDURE [dbo].[sp_UseStringList]
    @list StringList READONLY
AS
BEGIN
    -- Just return the items we passed in
    SELECT l.Item FROM @list l;
END

Finally here's some sql to use it in c#:

using (var con = new SqlConnection(connstring))
{
    con.Open();

    using (SqlCommand cmd = new SqlCommand("exec sp_UseStringList @list", con))
    {
        using (var table = new DataTable()) {
          table.Columns.Add("Item", typeof(string));

          for (int i = 0; i < 10; i++)
            table.Rows.Add("Item " + i.ToString());

          var pList = new SqlParameter("@list", SqlDbType.Structured);
          pList.TypeName = "dbo.StringList";
          pList.Value = table;

          cmd.Parameters.Add(pList);

          using (var dr = cmd.ExecuteReader())
          {
            while (dr.Read())
                Console.WriteLine(dr["Item"].ToString());
          }
         }
    }
}

To execute this from SSMS

DECLARE @list AS StringList

INSERT INTO @list VALUES ('Apple')
INSERT INTO @list VALUES ('Banana')
INSERT INTO @list VALUES ('Orange')

-- Alternatively, you can populate @list with an INSERT-SELECT
INSERT INTO @list
   SELECT Name FROM Fruits

EXEC sp_UseStringList @list

Comparing various suggestions (as well as comparing in the context of single-character replacements with various sizes and positions of the target).

In this particular case, splitting on the targets and joining on the replacements (in this case, empty string) is the fastest by at least a factor of 3. Ultimately, performance is different depending on the number of replacements, where the replacements are in the source, and the size of the source. #ymmv

        break;
    case (x < 12):
        alert("between 9 and 11");
        break;
    default:
        alert("none");
        break;

This is one way of installing pip on a Windows system.

1. Download the "get-pip" python script from here: https://bootstrap.pypa.io/get-pip.py

2. Save the file as getpip.py

3. Run it from cmd: python getpip.py install

In modern browsers you can do:

Mhh.. I think @Damian asks for remove undefined field (property) from an JS object. Then, I would simply do :

for (const i in myObj)  
   if (typeof myObj[i] === 'undefined')   
     delete myObj[i]; 

Short and efficient solution, in (vanilla) JS ! Example :

const myObj = {_x000D_
  a: 1,_x000D_
  b: undefined,_x000D_
  c: null, _x000D_
  d: 'hello world'_x000D_
};_x000D_
_x000D_
for (const i in myObj)  _x000D_
  if (typeof myObj[i] === 'undefined')   _x000D_
    delete myObj[i]; _x000D_
_x000D_
console.log(myObj);

A .war file is a Web Application Archive which runs inside an application server while a .jar is Java Application Archive that runs a desktop application on a user's machine.

Solved.

I was running into the exact same error message when trying to execute the following script (partial) against a remote VM that was configured to be in the WORKGROUP.

Restart-Computer -ComputerName MyComputer -Authentication Default -Credential $cred -force

I noticed I could run the script from another VM in the same WORKGROUP when I disabled the firewall but still couldn't do it from a machine on the domain. Those two things along with Stackflow suggestions is what brought me to the following solution:

Note: Change these settings at your own risk. You should understand the security implications of these changes before applying them.

On the remote machine:

• Make sure you re-enable your Firewall if you've disabled it during testing.
• Run Enable-PSRemoting from PowerShell with success
• Go into wf.msc (Windows Firewall with Advanced Security)
• Confirm the Private/Public inbound 'Windows Management Instrumentation (DCOM-In)' rule is enabled AND make sure the 'Remote Address' property is 'Any' or something more secure.
• Confirm the Private/Public inbound 'Windows Management Instrumentation (WMI-In)' rule is enabled AND make sure the 'Remote Address' property is 'Any' or something more secure.

Optional: You may also need to perform the following if you want to run commands like 'Enter-PSSession'.

• Confirm the Private/Public inbound 'Windows Management Instrumentation (ASync-In)' rule is enabled AND make sure the 'Remote Address' property is 'Any' or something more secure.
• Open up an Inbound TCP port to 5985

IMPORTANT! - It's taking my remote VM about 2 minutes or so after it reboots to respond to the 'Enter-PSSession' command even though other networking services are starting up without problems. Give it a couple minutes and then try.

Side Note: Before I changed the 'Remote Address' property to 'Any', both of the rules were set to 'Local subnet'.

If you use CURLOPT_COOKIE_FILE and CURLOPT_COOKIE_JAR curl will read/write the cookies from/to a file. You can, after curl is done with it, read and/or modify it however you want.

If you want n bits specific then you could first create a bitmask and then AND it with your number to take the desired bits.

Simple function to create mask from bit a to bit b.

unsigned createMask(unsigned a, unsigned b)
{
   unsigned r = 0;
   for (unsigned i=a; i<=b; i++)
       r |= 1 << i;

   return r;
}

You should check that a<=b.

If you want bits 12 to 16 call the function and then simply & (logical AND) r with your number N

r = createMask(12,16);
unsigned result = r & N;

If you want you can shift the result. Hope this helps

The key system must have several properties:

• very few keys must be valid
• valid keys must not be derivable even given everything the user has.
• a valid key on one system is not a valid key on another.
• others

One solution that should give you these would be to use a public key signing scheme. Start with a "system hash" (say grab the macs on any NICs, sorted, and the CPU-ID info, plus some other stuff, concatenate it all together and take an MD5 of the result (you really don't want to be handling personally identifiable information if you don't have to)) append the CD's serial number and refuse to boot unless some registry key (or some datafile) has a valid signature for the blob. The user activates the program by shipping the blob to you and you ship back the signature.

Potential issues include that you are offering to sign practically anything so you need to assume someone will run a chosen plain text and/or chosen ciphertext attacks. That can be mitigated by checking the serial number provided and refusing to handle request from invalid ones as well as refusing to handle more than a given number of queries from a given s/n in an interval (say 2 per year)

I should point out a few things: First, a skilled and determined attacker will be able to bypass any and all security in the parts that they have unrestricted access to (i.e. everything on the CD), the best you can do on that account is make it harder to get illegitimate access than it is to get legitimate access. Second, I'm no expert so there could be serious flaws in this proposed scheme.

You have not defined the variable input_line.

Add this:

string input_line;

And add this include.

#include <string>

Here is the full example. I also removed the semi-colon after the while loop, and you should have getline inside the while to properly detect the end of the stream.

#include <iostream>
#include <string>

int main() {
    for (std::string line; std::getline(std::cin, line);) {
        std::cout << line << std::endl;
    }
    return 0;
}

SELECT CONVERT(DATETIME, CONVERT(varchar(10), GETDATE(), 101))

In vim open the file (e.g.: :e YOURFILEENTER), then

:set noendofline binary

It's a default font on Macs, but rare on PCs. Since it's not technically web-safe, some people may have it and some people may not. If you want to use a font like that, without using @font-face, you may want to write it out several different ways because it might not work the same for everyone.

I like using a font stack that touches on all bases like this:

font-family: "HelveticaNeue-Light", "Helvetica Neue Light", "Helvetica Neue", 
  Helvetica, Arial, "Lucida Grande", sans-serif;

This recommended font-family stack is further described in this CSS-Tricks snippet Better Helvetica which uses a font-weight: 300; as well.

With Oracle 11g R2 (at least with 11.2.02) there is a view named datapump_dir_objs.

SELECT * FROM datapump_dir_objs;

The view shows the NAME of the directory object, the PATH as well as READ and WRITE permissions for the currently connected user. It does not show any directory objects which the current user has no permission to read from or write to, though.

We use phabricator and don't push using git. I had to create bash alias which works on Linux/mac

vim ~/.bash_aliases

new_branch() {
    git checkout -b "$1"
    git branch --set-upstream-to=origin/master "$1"
}

save

source ~/.bash_aliases
new_branch test #instead of git checkout -b test
git pull

There's generally nothing particularly inefficient about it. It doesn't generally matter to the JVM that you've made a subclass and added a constructor to it-- that's a normal, everyday thing to do in an object-oriented language. I can think of quite contrived cases where you could cause an inefficiency by doing this (e.g. you have a repeatedly-called method that ends up taking a mixture of different classes because of this subclass, whereas ordinary the class passed in would be totally predictable-- in the latter case, the JIT compiler could make optimisations that are not feasible in the first). But really, I think the cases where it'll matter are very contrived.

I'd see the issue more from the point of view of whether you want to "clutter things up" with lots of anonymous classes. As a rough guide, consider using the idiom no more than you'd use, say, anonymous classes for event handlers.

In (2), you're inside the constructor of an object, so "this" refers to the object you're constructing. That's no different to any other constructor.

As for (3), that really depends on who's maintaining your code, I guess. If you don't know this in advance, then a benchmark that I would suggest using is "do you see this in the source code to the JDK?" (in this case, I don't recall seeing many anonymous initialisers, and certainly not in cases where that's the only content of the anonymous class). In most moderately sized projects, I'd argue you're really going to need your programmers to understand the JDK source at some point or other, so any syntax or idiom used there is "fair game". Beyond that, I'd say, train people on that syntax if you have control of who's maintaining the code, else comment or avoid.

The core reason is quite simple: Python does not find its modules directory, so it can of course not load encodings, too

Python doc on embedding says "Py_Initialize() calculates the module search path based upon its best guess" ... "In particular, it looks for a directory named lib/pythonX.Y"

Yet, if the modules are installed in (just) lib - relative to the python binary - above guess is wrong.

Although docs says that PYTHONHOME and PYTHONPATH are regarded, we observed that this was not the case; their actual presence or content was completely irrelevant.

The only thing that had an effect was a call to Py_SetPath() with e.g. [path-to]\lib as argument before Py_Initialize().

Sure this is only an option for an embedding scenario where one has direct access and control over the code; with a ready-made solution, special steps may be necessary to solve the issue.

IsEmpty() would be the quickest way to check for that.

IsNull() would seem like a similar solution, but keep in mind Null has to be assigned to the cell; it's not inherently created in the cell.

Also, you can check the cell by:

count()

counta()

Len(range("BCell").Value) = 0

I do not agree with the rules given in the original post. Here are my rules:

1) You use structs for performance when stored in arrays. (see also When are structs the answer?)

2) You need them in code passing structured data to/from C/C++

3) Do not use structs unless you need them:

• They behave different from "normal objects" (reference types) under assignment and when passing as arguments, which can lead to unexpected behavior; this is particularly dangerous if the person looking at the code does not know they are dealing with a struct.
• They cannot be inherited.
• Passing structs as arguments is more expensive than classes.

I used HttpRequestMessage and my problem got solved after doing so much research

[HttpPost]
public HttpResponseMessage PostProcedure(HttpRequestMessage req){
...
}

There are two methods you can use. Both require creating a user and a database.

By default psql connects to the database with the same name as the user. So there is a convention to make that the "user's database". And there is no reason to break that convention if your user only needs one database. We'll be using mydatabase as the example database name.

1. Using createuser and createdb, we can be explicit about the database name,

   $ sudo -u postgres createuser -s $USER
   $ createdb mydatabase
   $ psql -d mydatabase
   

   You should probably be omitting that entirely and letting all the commands default to the user's name instead.

   $ sudo -u postgres createuser -s $USER
   $ createdb
   $ psql
   

2. Using the SQL administration commands, and connecting with a password over TCP

   $ sudo -u postgres psql postgres
   

   And, then in the psql shell

   CREATE ROLE myuser LOGIN PASSWORD 'mypass';
   CREATE DATABASE mydatabase WITH OWNER = myuser;
   

   Then you can login,

   $ psql -h localhost -d mydatabase -U myuser -p <port>
   

   If you don't know the port, you can always get it by running the following, as the postgres user,

   SHOW port;
   

   Or,

   $ grep "port =" /etc/postgresql/*/main/postgresql.conf
   

Sidenote: the postgres user

I suggest NOT modifying the postgres user.

1. It's normally locked from the OS. No one is supposed to "log in" to the operating system as postgres. You're supposed to have root to get to authenticate as postgres.
2. It's normally not password protected and delegates to the host operating system. This is a good thing. This normally means in order to log in as postgres which is the PostgreSQL equivalent of SQL Server's SA, you have to have write-access to the underlying data files. And, that means that you could normally wreck havoc anyway.
3. By keeping this disabled, you remove the risk of a brute force attack through a named super-user. Concealing and obscuring the name of the superuser has advantages.

Another way to get the same result:

date <- strptime(v,format="%Y%m%d")

Completely agree with user Daniel Saidi. In Order to have Color for NotificationIcon I'm writing this answer.

For that you've to make icon like Silhouette and make some section Transparent wherever you wants to add your Colors. i.e,

You can add your color using

.setColor(your_color_resource_here)

NOTE : setColor is only available in Lollipop so, you've to check OSVersion

if (android.os.Build.VERSION.SDK_INT < Build.VERSION_CODES.LOLLIPOP) {
    Notification notification = new Notification.Builder(context)
    ...
} else {
    // Lollipop specific setColor method goes here.
    Notification notification = new Notification.Builder(context)
    ...
    notification.setColor(your_color)
    ...            
}

You can also achieve this using Lollipop as the target SDK.

All instruction regarding NotificationIcon given at Google Developer Console Notification Guide Lines.

Preferred Notification Icon Size 24x24dp

mdpi    @ 24.00dp   = 24.00px
hdpi    @ 24.00dp   = 36.00px
xhdpi   @ 24.00dp   = 48.00px

And also refer this link for Notification Icon Sizes for more info.
