This worked for me:

window.location.replace(window.location.pathname)

This is working fine for me

I have add dependency

compile 'commons-codec:commons-codec:1.9'

ref: http://mvnrepository.com/artifact/commons-codec/commons-codec/1.9

my function

public String encode(String key, String data) {
    try {

        Mac sha256_HMAC = Mac.getInstance("HmacSHA256");
        SecretKeySpec secret_key = new SecretKeySpec(key.getBytes("UTF-8"), "HmacSHA256");
        sha256_HMAC.init(secret_key);

        return new String(Hex.encodeHex(sha256_HMAC.doFinal(data.getBytes("UTF-8"))));

    } catch (NoSuchAlgorithmException e) {
        e.printStackTrace();
    } catch (InvalidKeyException e) {
        e.printStackTrace();

This will also work and you don't need the extra class:

#navigation li li {}

If you have a third level of LI's you may have to reset/override some of the styles they will inherit from the above selector. You can target the third level like so:

#navigation li li li {}

Go to USB Debugging and disable MIUI Inspection and allow the phone to reboot. Things should be fine from here

The note is firstly you must sure about filemode set to false in config git file, or use this command:

git config core.filemode false

and then you can set 0777 permission with this command:

git update-index --chmod=+x foo.sh

This worked for me:

src="{0}"  width=30 height=30 style="border:0;"

Nothing else has worked so far.

EDIT: The current best practices regarding Open Graph image sizes are officially outlined here: https://developers.facebook.com/docs/sharing/best-practices#images

There was a post in the Facebook developers group today, where one of the FB guys uploaded a PDF containing their new rules about image sizes – since that seems to be available only if you’re a member of the group, I uploaded it here: http://www.sendspace.com/file/ghqwhr

And they also said they will post about it in the developer blog in the coming days, so keep checking there as well

To summarize the linked document:

• Minimum size in pixels is 600x315
• Recommended size is 1200x630 - Images this size will get a larger display treatment.
• Aspect ratio should be 1.91:1

As mentioned in a comment (and another answer as I typed) you need to register an event handler to catch the keydown or keypress event on a text box. This is because TextChanged is only fired when the TextBox loses focus

The below regex lets you match those characters you want to allow

Regex regex = new Regex(@"[0-9+\-\/\*\(\)]");
MatchCollection matches = regex.Matches(textValue);

and this does the opposite and catches characters that aren't allowed

Regex regex = new Regex(@"[^0-9^+^\-^\/^\*^\(^\)]");
MatchCollection matches = regex.Matches(textValue);

I'm not assuming there'll be a single match as someone could paste text into the textbox. in which case catch textchanged

textBox1.TextChanged += new TextChangedEventHandler(textBox1_TextChanged);
private void textBox1_TextChanged(object sender, EventArgs e)
{
    Regex regex = new Regex(@"[^0-9^+^\-^\/^\*^\(^\)]");
    MatchCollection matches = regex.Matches(textBox1.Text);
    if (matches.Count > 0) {
       //tell the user
    }
}

and to validate single key presses

textBox1.KeyPress += new KeyPressEventHandler(textBox1_KeyPress);
private void textBox1_KeyPress(object sender, System.Windows.Forms.KeyPressEventArgs e)
{
    // Check for a naughty character in the KeyDown event.
    if (System.Text.RegularExpressions.Regex.IsMatch(e.KeyChar.ToString(), @"[^0-9^+^\-^\/^\*^\(^\)]"))
    {
        // Stop the character from being entered into the control since it is illegal.
        e.Handled = true;
    }
}

This may help you as well. This is a conditional statement that will fill the cell with a default date if it is empty but will subtract one hour if it is a valid date/time and put it into the cell.

=IF((Sheet1!C4)="",DATE(1999,1,1),Sheet1!C4-TIME(1,0,0))

You can also substitute TIME with DATE to add or subtract a date or time.

For the C-runtime go to the project settings, choose C/C++ then 'Code Generation'. Change the 'runtime library' setting to 'multithreaded' instead of 'multithreaded dll'.

If you are using any other libraries you may need to tell the linker to ignore the dynamically linked CRT explicitly.

int(hexstring, 16) does the trick, and works with and without the 0x prefix:

>>> int("a", 16)
10
>>> int("0xa", 16)
10

Here is the example directly from PEP 8 on limiting line length:

class Rectangle(Blob):

    def __init__(self, width, height,
                 color='black', emphasis=None, highlight=0):
        if (width == 0 and height == 0 and
                color == 'red' and emphasis == 'strong' or
                highlight > 100):
            raise ValueError("sorry, you lose")
        if width == 0 and height == 0 and (color == 'red' or
                                           emphasis is None):
            raise ValueError("I don't think so -- values are %s, %s" %
                             (width, height))
        Blob.__init__(self, width, height,
                      color, emphasis, highlight)

public static String getQueryMap(String query) {        
    String[] params = query.split("&");     
    for (String param : params) {           
       String name = param.split("=")[0];
       if ("YourParam".equals(name)) {
           return param.split("=")[1]; 
       }
    }
    return null;
}

import time 

startTime = time.time()
# Your code here !
print ('The script took {0} second !'.format(time.time() - startTime))

The previous code works for me with no problem !

int is a primitive data type while Integer is a Reference or Wrapper Type (Class) in Java.

after java 1.5 which introduce the concept of autoboxing and unboxing you can initialize both int or Integer like this.

int a= 9
Integer a = 9 // both valid After Java 1.5.

why Integer.parseInt("1"); but not int.parseInt("1"); ??

Integer is a Class defined in jdk library and parseInt() is a static method belongs to Integer Class

So, Integer.parseInt("1"); is possible in java. but int is primitive type (assume like a keyword) in java. So, you can't call parseInt() with int.

The async way of life:

#! /usr/bin/node

const fs = require('fs');

function readall (stream)
{
  return new Promise ((resolve, reject) => {
    const chunks = [];
    stream.on ('error', (error) => reject (error));
    stream.on ('data',  (chunk) => chunk && chunks.push (chunk));
    stream.on ('end',   ()      => resolve (Buffer.concat (chunks)));
  });
}

function readfile (filename)
{
  return readall (fs.createReadStream (filename));
}

(async () => {
  let content = await readfile ('/etc/ssh/moduli').catch ((e) => {})
  if (content)
    console.log ("size:", content.length,
                 "head:", content.slice (0, 46).toString ());
})();

Your compiler may have a warning that it can generate if a base class function becomes hidden. If it does, enable it. That will catch const clashes and differences in parameter lists. Unfortunately this won't uncover a spelling error.

For example, this is warning C4263 in Microsoft Visual C++.

In the early days...like before the 90s...the processors weren't able to do multi tasks that efficiently...coz a single processor could handle just a single task...so when we used to say that my antivirus,microsoft word,vlc,etc. softwares are all running at the same time...that isn't actually true. When I said a processor could handle a single process at a time...I meant it. It actually would process a single task...then it used to pause that task...take another task...complete it if its a short one or again pause it and add it to the queue...then the next. But this 'pause' that I mentioned was so small (appx. 1ns) that you didn't understand that the task has been paused. Eg. On vlc while listening to music there are other apps running simultaneously but as I told you...one program at a time...so the vlc is actually pausing in between for ns so you dont underatand it but the music is actually stopping in between.

But this was about the old processors...

Now-a- days processors ie 3rd gen pcs have multi cored processors. Now the 'cores' can be compared to a 1st or 2nd gen processors itself...embedded onto a single chip, a single processor. So now we understood what are cores ie they are mini processors which combine to become a processor. And each core can handle a single process at a time or multi threads as designed for the OS. And they folloq the same steps as I mentioned above about the single processor.

Eg. A i7 6gen processor has 8 cores...ie 8 mini processors in 1 i7...ie its speed is 8x times the old processors. And this is how multi tasking can be done.

There could be hundreds of cores in a single processor Eg. Intel i128.

I hope I explaned this well.

Another option (just so you've seen it):

$(function () {
    $(".inputs").click(function (e) {
         alert(e.target.id);
    });
});

HTH.

Very simple answer for this problem that seems to catch a lot of people:

<img src="url-to-image">
<p>Nullam id dolor id nibh ultricies vehicula ut id elit.</p>

    img {
        float: left;
    }
    p {
        overflow: hidden;
    }

See example: http://jsfiddle.net/vandigroup/upKGe/132/

.prop('disabled') will return a Boolean:

var isDisabled = $('textbox').prop('disabled');

You can add a new series, and name it at the same time. The name will be the index of the new row, and all the values will automatically be NaN.

df.append(pd.Series(name='Afterthought'))

The standard MIME type is application/pdf. The assignment is defined in RFC 3778, The application/pdf Media Type, referenced from the MIME Media Types registry.

MIME types are controlled by a standards body, The Internet Assigned Numbers Authority (IANA). This is the same organization that manages the root name servers and the IP address space.

The use of x-pdf predates the standardization of the MIME type for PDF. MIME types in the x- namespace are considered experimental, just as those in the vnd. namespace are considered vendor-specific. x-pdf might be used for compatibility with old software.

From a quick google search it seems that the problem is a file or url couldn't be found be the HTTPservice.

useState is a Hook that allows you to have state variables in functional components.

There are two types of components in React: class and functional components.

Class components are ES6 classes that extend from React.Component and can have state and lifecycle methods:

class Message extends React.Component {
constructor(props) {
super(props);
this.state = {
  message: ‘’    
 };
}

componentDidMount() {
/* ... */
 }

render() {
return <div>{this.state.message}</div>;
  }
}

Functional components are functions that just accept arguments as the properties of the component and return valid JSX:

function Message(props) {
  return <div>{props.message}</div>
 }
// Or as an arrow function
const Message = (props) =>  <div>{props.message}</div>

As you can see, there are no state or lifecycle methods.

I recently had a similar problem and I found that I need to decrease the list index by one.

So instead of:

if l[i]==0:

You can try:

if l[i-1]==0:

Because the list indices start at 0 and your range will go just one above that.

I found this blog post to be very helpful (I am not the author). Summarizing (please read, though):

...delimited identifiers are case sensitive ("table_name" != "Table_Name"), while non quoted identifiers are not, and are transformed to upper case (table_name => TABLE_NAME).

He found DB2, Oracle and Interbase/Firebird are 100% compliant:

PostgreSQL ... lowercases every unquoted identifier, instead of uppercasing it. MySQL ... file system dependent. SQLite and SQL Server ... case of the table and field names are preserved on creation, but they are completely ignored afterwards.

I had this error when i renamed the pc in the windows-properties. The pc-name must be updated in the listener.ora-file

I think I may have a better solution for having a fully responsive iframe (a vimeo video in my case) embed on your site. Nest the iframe in a div. Give them the following styles:

div {
    width: 100%;
    height: 0;
    padding-bottom: 56%; /* Change this till it fits the dimensions of your video */
    position: relative;
}

div iframe {
    width: 100%;
    height: 100%;
    position: absolute;
    display: block;
    top: 0;
    left: 0;
}

Just did it now for a client, and it seems to be working: http://themilkrunsa.co.za/

If you know it's going to be just two fields, you can skip the extra subprocesses like this:

var1=${STR%-*}
var2=${STR#*-}

What does this do? ${STR%-*} deletes the shortest substring of $STR that matches the pattern -* starting from the end of the string. ${STR#*-} does the same, but with the *- pattern and starting from the beginning of the string. They each have counterparts %% and ## which find the longest anchored pattern match. If anyone has a helpful mnemonic to remember which does which, let me know! I always have to try both to remember.

Using Javascript

   <div id="mydiv" style="width:200px;background:white" onmouseover="this.style.background='gray';" onmouseout="this.style.background='white';">
    Jack and Jill went up the hill 
    To fetch a pail of water. 
    Jack fell down and broke his crown, 
    And Jill came tumbling after. 
    </div>

You can do this with JavaScript.

document.getElementById('foo').height = document.getElementById('foo').contentWindow.document.body.scrollHeight + "px";

You can make full use of the && and || operators like this:

ps aux | grep some_proces[s] > /tmp/test.txt && echo 1 || echo 0

For excluding grep itself, you could also do something like:

ps aux | grep some_proces | grep -vw grep > /tmp/test.txt && echo 1 || echo 0

Put the entire script into a template string, with {SERVERNAME} placeholders. Then edit the string using:

SET @SQL_SCRIPT = REPLACE(@TEMPLATE, '{SERVERNAME}', @DBNAME)

and then run it with

EXECUTE (@SQL_SCRIPT)

It's hard to believe that, in the course of three years, nobody noticed that my code doesn't work!

You can't EXEC multiple batches. GO is a batch separator, not a T-SQL statement. It's necessary to build three separate strings, and then to EXEC each one after substitution.

I suppose one could do something "clever" by breaking the single template string into multiple rows by splitting on GO; I've done that in ADO.NET code.

And where did I get the word "SERVERNAME" from?

Here's some code that I just tested (and which works):

DECLARE @DBNAME VARCHAR(255)
SET @DBNAME = 'TestDB'

DECLARE @CREATE_TEMPLATE VARCHAR(MAX)
DECLARE @COMPAT_TEMPLATE VARCHAR(MAX)
DECLARE @RECOVERY_TEMPLATE VARCHAR(MAX)

SET @CREATE_TEMPLATE = 'CREATE DATABASE {DBNAME}'
SET @COMPAT_TEMPLATE='ALTER DATABASE {DBNAME} SET COMPATIBILITY_LEVEL = 90'
SET @RECOVERY_TEMPLATE='ALTER DATABASE {DBNAME} SET RECOVERY SIMPLE'

DECLARE @SQL_SCRIPT VARCHAR(MAX)

SET @SQL_SCRIPT = REPLACE(@CREATE_TEMPLATE, '{DBNAME}', @DBNAME)
EXECUTE (@SQL_SCRIPT)

SET @SQL_SCRIPT = REPLACE(@COMPAT_TEMPLATE, '{DBNAME}', @DBNAME)
EXECUTE (@SQL_SCRIPT)

SET @SQL_SCRIPT = REPLACE(@RECOVERY_TEMPLATE, '{DBNAME}', @DBNAME)
EXECUTE (@SQL_SCRIPT)

You can use this code to retrieve values from multiple select combo box

HTML:

<form action="c3.php" method="post">
  <select name="ary[]" multiple="multiple">
    <option value="Option 1" >Option 1</option>
    <option value="Option 2">Option 2</option>
    <option value="Option 3">Option 3</option>
    <option value="Option 4">Option 4</option>
    <option value="Option 5">Option 5</option>
  </select>
  <input type="submit">
</form>

PHP:

<?php
$values = $_POST['ary'];

foreach ($values as $a){
    echo $a;
}
?>

Beautify (Github) & Prettier (Github) are the best plugin for web development in Visual Studio Code.

var groupedCustomerList = CustomerList.GroupBy(u => u.GroupID)
                                      .Select(grp =>new { GroupID =grp.Key, CustomerList = grp.ToList()})
                                      .ToList();

Put the following style at the 'input' text element: position: relative; z-index: 100000;.

The datepicker div takes the z-index from the input, but this works only if the position is relative.

Using this way you don't have to modify any javascript from jQuery UI.

After carefully going through the thread here and checking all the solutions proposed by people, I can confidently claim this, after following the steps mentioned on Apple developer docs for creating CSR and mobile provision file, just do this!,

1. Launch Xcode.
2. Select window->Organizer
3. Click this refresh button and that filthy yellow bar will remove instantly.

http://img.skitch.com/20100820-1ngm8an14c6fm3dt7g6j51d2nx.jpg

Trust me, you only have to do this. There is no need to repeat the process again and again to make sure that you doing it the right way. Just press Refresh, enter your login credentials and it's done.

One wrinkle I ran into (that isn't covered in other answers):

Suppose you have these namespaces:

• Something.Other
• Parent.Something.Other

When you use using Something.Other outside of a namespace Parent, it refers to the first one (Something.Other).

However if you use it inside of that namespace declaration, it refers to the second one (Parent.Something.Other)!

There is a simple solution: add the "global::" prefix: docs

namespace Parent
{
   using global::Something.Other;
   // etc
}

The simple solution that worked for me is: change localhost to 127.0.0.1 in your database.yml or in your script if writing one.

A query string is an array of parameters sent to a web page.

This url: http://page.asp?x=1&y=hello

Request.QueryString[0] is the same as 
Request.QueryString["x"] and holds a string value "1"

Request.QueryString[1] is the same as 
Request.QueryString["y"] and holds a string value "hello"

It works, in my case for Xcode from 7.3 TO 7.1. Copy directory 9.2, for iOS device OS 9.2.1.

Just check that Oracle services enabled

in windows

CTRL + ALT + DEL

I created an extension method on ObjectStateEntry to be able to flag properties (of Entity Framework POCO classes) as modified in a type safe manner, since the default method only accepts a string. Here's my way of getting the name from the property:

public static void SetModifiedProperty<T>(this System.Data.Objects.ObjectStateEntry state, Expression<Func<T>> action)
{
    var body = (MemberExpression)action.Body;
    string propertyName = body.Member.Name;

    state.SetModifiedProperty(propertyName);
}

function hour_min($minutes){// Total
   if($minutes <= 0) return '00 Hours 00 Minutes';
else    
   return sprintf("%02d",floor($minutes / 60)).' Hours '.sprintf("%02d",str_pad(($minutes % 60), 2, "0", STR_PAD_LEFT)). " Minutes";
}
echo hour_min(250); //Function Call will return value : 04 Hours 10 Minutes

You must use the column names and then set the values to insert (both ? marks):

//insert 1st row            
String inserting = "INSERT INTO employee(emp_name ,emp_address) values(?,?)";
System.out.println("insert " + inserting);//
PreparedStatement ps = con.prepareStatement(inserting); 
ps.setString(1, "hans");
ps.setString(2, "germany");
ps.executeUpdate();

I had a similar issue.

The problem was, on Windows, in the index, the file was added in a case different from what was in the unstaged area. For example, in the index, the file was name xx.txt and in the unstaged area, the file was names Xx.txt.

Removed the file with the incorrect case from the index (xx.txt). Then, I have been able to add the file with the correct case (Xx.txt).

You can also simply inject the location into the scope and use that to deduct the style for the navigation:

function IndexController( $scope, $rootScope, $location ) {
  $rootScope.location = $location;
  ...
}

Then use it in your ng-class:

<li ng-class="{active: location.path() == '/search'}">
  <a href="/search">Search><a/>
</li>

in a custom UITableViewCell -controller add this

-(void)layoutSubviews {  

    CGRect newCellSubViewsFrame = CGRectMake(0, 0, self.frame.size.width, self.frame.size.height);
    CGRect newCellViewFrame = CGRectMake(self.frame.origin.x, self.frame.origin.y, self.frame.size.width, self.frame.size.height);

    self.contentView.frame = self.contentView.bounds = self.backgroundView.frame = self.accessoryView.frame = newCellSubViewsFrame;
    self.frame = newCellViewFrame;

    [super layoutSubviews];
}

In the UITableView -controller add this

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
    return [indexPath row] * 1.5; // your dynamic height...
}

For MySQL you can directly put conditions in SUM() function and it will be evaluated as Boolean 0 or 1 and thus you can have your count based on your criteria without using IF/CASE statements

SELECT
    company_name,  
    SUM(action = 'EMAIL')AS Email,
    SUM(action = 'PRINT' AND pagecount = 1)AS Print1Pages,
    SUM(action = 'PRINT' AND pagecount = 2)AS Print2Pages,
    SUM(action = 'PRINT' AND pagecount = 3)AS Print3Pages
FROM t
GROUP BY company_name

DEMO

I didn't find it listed so updating the list.

You need to have the apk installed and running in front on your phone for this solution:

Windows CMD line:

adb shell dumpsys window windows | findstr <any unique string from your pkg Name>

Linux Terminal:

adb shell dumpsys window windows | grep -i <any unique string from your Pkg Name>

OUTPUT for Calculator package would be:

Window #7 Window{39ced4b1 u0 com.android.calculator2/com.android.calculator2.Calculator}:

    mOwnerUid=10036 mShowToOwnerOnly=true package=com.android.calculator2 appop=NONE

    mToken=AppWindowToken{29a4bed4 token=Token{2f850b1a ActivityRecord{eefe5c5 u0 com.android.calculator2/.Calculator t322}}}

    mRootToken=AppWindowToken{29a4bed4 token=Token{2f850b1a ActivityRecord{eefe5c5 u0 com.android.calculator2/.Calculator t322}}}

    mAppToken=AppWindowToken{29a4bed4 token=Token{2f850b1a ActivityRecord{eefe5c5 u0 com.android.calculator2/.Calculator t322}}}

    WindowStateAnimator{3e160d22 com.android.calculator2/com.android.calculator2.Calculator}:

      mSurface=Surface(name=com.android.calculator2/com.android.calculator2.Calculator)

  mCurrentFocus=Window{39ced4b1 u0 com.android.calculator2/com.android.calculator2.Calculator}

  mFocusedApp=AppWindowToken{29a4bed4 token=Token{2f850b1a ActivityRecord{eefe5c5 u0 com.android.calculator2/.Calculator t322}}}

Main part is, First Line:

Window #7 Window{39ced4b1 u0 com.android.calculator2/com.android.calculator2.Calculator}:

First part of the output is package name:

com.android.calculator2

Second Part of output (which is after /) can be two things, in our case its:

com.android.calculator2.Calculator

1. <PKg name>.<activity name> = <com.android.calculator2>.<Calculator>

   so .Calculator is our activity

2. If second part is entirely different from Package name and doesn't seem to contain pkg name which was before / in out output, then entire second part can be used as main activity.

The above error in my case was actually due to the wrong username and password. Solving the issue: 1. Go to the line DriverManager.getConnection("jdbc:mysql://localhost:3306/?useSSL=false", "username", "password"); The fields username and password might be wrong. Enter the username and password which you use to start your mysql client. The username is generally root and password is the string which you enter when a screen similar to this appears Startup screen of mysql

Note: The portname 3306 might be different in your case.

Actually… there is! Sort of. box-shadow defaults to color, just like border does.

According to http://dev.w3.org/.../#the-box-shadow

The color is the color of the shadow. If the color is absent, the used color is taken from the ‘color’ property.

In practice, you have to change the color property and leave box-shadow without a color:

box-shadow: 1px 2px 3px;
color: #a00;

Support

• Safari 6+
• Chrome 20+ (at least)
• Firefox 13+ (at least)
• IE9+ (IE8 doesn't support box-shadow at all)

The bug mentioned in the comment below has since been fixed :)

Just to warn, that in case of a deque container, all solutions that check for the deque iterator equality to numbers.end() will likely fail on gcc 4.8.4. Namely, erasing an element of the deque generally invalidates pointer to numbers.end():

#include <iostream>
#include <deque>

using namespace std;
int main() 
{

  deque<int> numbers;

  numbers.push_back(0);
  numbers.push_back(1);
  numbers.push_back(2);
  numbers.push_back(3);
  //numbers.push_back(4);

  deque<int>::iterator  it_end = numbers.end();

  for (deque<int>::iterator it = numbers.begin(); it != numbers.end(); ) {
    if (*it % 2 == 0) {
      cout << "Erasing element: " << *it << "\n";
      numbers.erase(it++);
      if (it_end == numbers.end()) {
    cout << "it_end is still pointing to numbers.end()\n";
      } else {
    cout << "it_end is not anymore pointing to numbers.end()\n";
      }
    }
    else {
      cout << "Skipping element: " << *it << "\n";
      ++it;
    }
  }
}

Output:

Erasing element: 0
it_end is still pointing to numbers.end()
Skipping element: 1
Erasing element: 2
it_end is not anymore pointing to numbers.end()

Note that while the deque transformation is correct in this particular case, the end pointer has been invalidated along the way. With the deque of a different size the error is more apparent:

int main() 
{

  deque<int> numbers;

  numbers.push_back(0);
  numbers.push_back(1);
  numbers.push_back(2);
  numbers.push_back(3);
  numbers.push_back(4);

  deque<int>::iterator  it_end = numbers.end();

  for (deque<int>::iterator it = numbers.begin(); it != numbers.end(); ) {
    if (*it % 2 == 0) {
      cout << "Erasing element: " << *it << "\n";
      numbers.erase(it++);
      if (it_end == numbers.end()) {
    cout << "it_end is still pointing to numbers.end()\n";
      } else {
    cout << "it_end is not anymore pointing to numbers.end()\n";
      }
    }
    else {
      cout << "Skipping element: " << *it << "\n";
      ++it;
    }
  }
}

Output:

Erasing element: 0
it_end is still pointing to numbers.end()
Skipping element: 1
Erasing element: 2
it_end is still pointing to numbers.end()
Skipping element: 3
Erasing element: 4
it_end is not anymore pointing to numbers.end()
Erasing element: 0
it_end is not anymore pointing to numbers.end()
Erasing element: 0
it_end is not anymore pointing to numbers.end()
...
Segmentation fault (core dumped)

Here is one of the ways to fix this:

#include <iostream>
#include <deque>

using namespace std;
int main() 
{

  deque<int> numbers;
  bool done_iterating = false;

  numbers.push_back(0);
  numbers.push_back(1);
  numbers.push_back(2);
  numbers.push_back(3);
  numbers.push_back(4);

  if (!numbers.empty()) {
    deque<int>::iterator it = numbers.begin();
    while (!done_iterating) {
      if (it + 1 == numbers.end()) {
    done_iterating = true;
      } 
      if (*it % 2 == 0) {
    cout << "Erasing element: " << *it << "\n";
      numbers.erase(it++);
      }
      else {
    cout << "Skipping element: " << *it << "\n";
    ++it;
      }
    }
  }
}

use the built in float() function in a list comprehension.

A2 = [float(v.replace('"','').strip()) for v in A1]

This should work:

 cat "$API" >> "$CONFIG"

You need to use the >> operator to append to a file. Redirecting with > causes the file to be overwritten. (truncated).

I also had the same problem. I added the following. It works for me

Microsoft.EntityFrameworkCore.SqlServer

You need to pass an array of element to jsx. The problem is that forEach does not return anything (i.e it returns undefined). So it's better to use map because map returns an array:

class QuestionSet extends Component {
render(){ 
    <div className="container">
       <h1>{this.props.question.text}</h1>
       {this.props.question.answers.map((answer, i) => {     
           console.log("Entered");                 
           // Return the element. Also pass key     
           return (<Answer key={answer} answer={answer} />) 
        })}
}

export default QuestionSet;

For Python >= 2.7, use subprocess.check_output().

http://docs.python.org/2/library/subprocess.html#subprocess.check_output

See this table.

A 101x101 QR code, with high level error correction, can hold 3248 bits, or 406 bytes. Probably not enough for any meaningful SVG/XML data.

A 177x177 grid, depending on desired level of error correction, can store between 1273 and 2953 bytes. Maybe enough to store something small.

Here's something that I quickly wrote; I'm sure it can be improved upon.

Please use the below mysql query.

SELECT COLUMN_NAME, DATA_TYPE, CHARACTER_MAXIMUM_LENGTH 
FROM information_schema.columns 
WHERE table_schema = '<DATABASE NAME>' 
AND table_name = '<TABLE NAME>' 
AND COLUMN_NAME = '<COLOMN NAME>' 

You would need to create a generic class named MyProp. Then, you will need to add implicit or explicit cast operators so you can get and set the value as if it were the type specified in the generic type parameter. These cast operators can do the extra work that you need.

You are checking whether the string contains all illegal characters. Change the ||s to &&s.

Answer provided by Nicholas Krasnov

SELECT *
FROM BOOKING_SESSION
WHERE TO_CHAR(T_SESSION_DATETIME, 'DD-MM-YYYY') ='20-03-2012';

The way I always do it (assuming the data is never to be deleted, only inserted) is to

• Firstly do an insert, if this fails with a unique constraint violation then you know the row is there,
• Then do an update

Unfortunately many frameworks such as Hibernate treat all database errors (e.g. unique constraint violation) as unrecoverable conditions, so it isn't always easy. (In Hibernate the solution is to open a new session/transaction just to execute this one insert command.)

You can't just do a select count(*) .. where .. as even if that returns zero, and therefore you choose to do an insert, between the time you do the select and the insert someone else might have inserted the row and therefore your insert will fail.

In Python 2 dict.keys() return a list, whereas in Python 3 it returns a generator.

You could only iterate over it's values else you may have to explicitly convert it to a list i.e. pass it to a list function.

I thought I would answer my own question, since I'm taking a different path than suggested in the answers. Nonetheless, thanks to those who answered.

First, a brief synopsis of my experiences with GitPython, PyGit, and Dulwich:

• GitPython: After downloading, I got this imported and the appropriate object initialized. However, trying to do what was suggested in the tutorial led to errors. Lacking more documentation, I turned elsewhere.
• PyGit: This would not even import, and I could find no documentation.
• Dulwich: Seems to be the most promising (at least for what I wanted and saw). I made some progress with it, more than with GitPython, since its egg comes with Python source. However, after a while, I decided it may just be easier to try what I did.

Also, StGit looks interesting, but I would need the functionality extracted into a separate module and do not want wait for that to happen right now.

In (much) less time than I spent trying to get the three modules above working, I managed to get git commands working via the subprocess module, e.g.

def gitAdd(fileName, repoDir):
    cmd = ['git', 'add', fileName]
    p = subprocess.Popen(cmd, cwd=repoDir)
    p.wait()

gitAdd('exampleFile.txt', '/usr/local/example_git_repo_dir')

This isn't fully incorporated into my program yet, but I'm not anticipating a problem, except maybe speed (since I'll be processing hundreds or even thousands of files at times).

Maybe I just didn't have the patience to get things going with Dulwich or GitPython. That said, I'm hopeful the modules will get more development and be more useful soon.

You can use these queries:

select * from all_tab_privs;
select * from dba_sys_privs;
select * from dba_role_privs;

Each of these tables have a grantee column, you can filter on that in the where criteria:

where grantee = 'A'

To query privileges on objects (e.g. tables) in other schema I propose first of all all_tab_privs, it also has a table_schema column.

If you are logged in with the same user whose privileges you want to query, you can use user_tab_privs, user_sys_privs, user_role_privs. They can be queried by a normal non-dba user.

Came here with a similar question, the above didn't work for me in: "rxjs": "^6.0.0", in order to generate an observable that emits no data I needed to do:

import {Observable,empty} from 'rxjs';
class ActivatedRouteStub {
  params: Observable<any> = empty();
}

Given the following sample

myData <- data.frame(A=rep(1:2, 3), B=rep(1:3, 2), Pulse=20:25)  

then

myData$A <-as.factor(myData$A)
myData$B <-as.factor(myData$B)

or you could select your columns altogether and wrap it up nicely:

# select columns
cols <- c("A", "B")
myData[,cols] <- data.frame(apply(myData[cols], 2, as.factor))

levels(myData$A) <- c("long", "short")
levels(myData$B) <- c("1kg", "2kg", "3kg")

To obtain

> myData
      A   B Pulse
1  long 1kg    20
2 short 2kg    21
3  long 3kg    22

I dont't know why nobody has pointed this out but here's is a way of doing it without any Javascript and it's also compatible with any browser.

EDIT: In Safari, the input gets disabled when hidden with display: none. A better approach would be to use position: fixed; top: -100em.

<label>
  Open file dialog
  <input type="file" style="position: fixed; top: -100em">
</label>

If you prefer you can go the "correct way" by using for in the label pointing to the id of the input like this:

<label for="inputId">file dialog</label>
<input id="inputId" type="file" style="position: fixed; top: -100em">

https://angular.io/guide/user-input - there's a simple example .

Without wanting to give you the answer here is the logic.

You have 2 possible values in each digit. you have 9 of them.

like in base 10 where you have 10 different values by digit say you have 2 of them (which makes from 0 to 99) : 0 to 99 makes 100 numbers. if you do the calcul you have an exponential function

base^numberOfDigits:
10^2 = 100 ;
2^9 = 512

I created the cross-platform Service Manager software a few years back so that I could start PHP and other scripting languages as system services on Windows, Mac, and Linux OSes:

https://github.com/cubiclesoft/service-manager

Service Manager is a set of precompiled binaries that install and manage a system service on the target OS using nearly identical command-line options (source code also available). Each platform does have subtle differences but the core features are mostly normalized.

If the child process dies, Service Manager automatically restarts it.

Processes that are started with Service Manager should periodically watch for two notification files to handle restart and reload requests but they don't necessarily have to do that. Service Manager will force restart the child process if it doesn't respond in a timely fashion to controlled restart/reload requests.

I had the same problem as one of my <div>'s had the margin set by the browser. It was quite annoying but then I figured out as most of the people said, it's a markup error.

I went back and checked my <head> section and my CSS link was like below:

<link rel="stylesheet" href="ex.css">

I included type in it and made it like below:

<link rel="stylesheet" type="text/css" href="ex.css">

My problem was solved.

You can also use

postMessage(message, '*');

Powershell provides a lot of built-in support for common parameter scenarios, including mandatory parameters, optional parameters, "switch" (aka flag) parameters, and "parameter sets."

By default, all parameters are optional. The most basic approach is to simply check each one for $null, then implement whatever logic you want from there. This is basically what you have already shown in your sample code.

Add a shortcut:

$.Shortcuts.add({
    type: 'down',
    mask: 'Ctrl+A',
    handler: function() {
        debug('Ctrl+A');
    }
});

Start reacting to shortcuts:

$.Shortcuts.start();

Add a shortcut to “another” list:

$.Shortcuts.add({
    type: 'hold',
    mask: 'Shift+Up',
    handler: function() {
        debug('Shift+Up');
    },
    list: 'another'
});

Activate “another” list:

$.Shortcuts.start('another');
Remove a shortcut:
$.Shortcuts.remove({
    type: 'hold',
    mask: 'Shift+Up',
    list: 'another'
});

Stop (unbind event handlers):

$.Shortcuts.stop();

The Apple Transition Guide mentions a button at the top left of the Xcode screen, but I cannot see it in Xcode 4.3.

CALayer * pLayer = self.layer.presentationLayer;
[UIView setAnimationBeginsFromCurrentState:YES];
[UIView animateWithDuration:0.001 animations:^{
    self.frame = pLayer.frame;
}];

First, use the bounding boxes as described by Jonathan Holland to find if you may have a collision.

From the (multi-color) sprites, create black and white versions. You probably already have these if your sprites are transparent (i.e. there are places which are inside the bounding box but you can still see the background). These are "masks".

Use Image.getRGB() on the mask to get at the pixels. For each pixel which isn't transparent, set a bit in an integer array (playerArray and enemyArray below). The size of the array is height if width <= 32 pixels, (width+31)/32*height otherwise. The code below is for width <= 32.

If you have a collision of the bounding boxes, do this:

// Find the first line where the two sprites might overlap
int linePlayer, lineEnemy;
if (player.y <= enemy.y) {
    linePlayer = enemy.y - player.y;
    lineEnemy = 0;
} else {
    linePlayer = 0;
    lineEnemy = player.y - enemy.y;
}
int line = Math.max(linePlayer, lineEnemy);

// Get the shift between the two
x = player.x - enemy.x;
int maxLines = Math.max(player.height, enemy.height);
for ( line < maxLines; line ++) {
    // if width > 32, then you need a second loop here
    long playerMask = playerArray[linePlayer];
    long enemyMask = enemyArray[lineEnemy];
    // Reproduce the shift between the two sprites
    if (x < 0) playerMask << (-x);
    else enemyMask << x;
    // If the two masks have common bits, binary AND will return != 0
    if ((playerMask & enemyMask) != 0) {
        // Contact!
    }

}

Regarding CMake 3.13.3, platform Windows, and IDE Visual Studio 2017, I suggest this guide. In brief I suggest:
1. Download cmake > unzip it > execute it.
2. As example download GLFW > unzip it > create inside folder Build.
3. In cmake Browse "Source" > Browse "Build" > Configure and Generate.
4. In Visual Studio 2017 Build your Solution.
5. Get the binaries.

Fatal Error gave a straightforward possibility: source your second script! if you're worried that this second script may alter some of your precious variables, you can always source it in a subshell:

( . ./test2.sh )

The parentheses will make the source happen in a subshell, so that the parent shell will not see the modifications test2.sh could perform.

There's another possibility that should definitely be referenced here: use set -a.

From the POSIX set reference:

-a: When this option is on, the export attribute shall be set for each variable to which an assignment is performed; see the Base Definitions volume of IEEE Std 1003.1-2001, Section 4.21, Variable Assignment. If the assignment precedes a utility name in a command, the export attribute shall not persist in the current execution environment after the utility completes, with the exception that preceding one of the special built-in utilities causes the export attribute to persist after the built-in has completed. If the assignment does not precede a utility name in the command, or if the assignment is a result of the operation of the getopts or read utilities, the export attribute shall persist until the variable is unset.

From the Bash Manual:

-a: Mark variables and function which are modified or created for export to the environment of subsequent commands.

So in your case:

set -a
TESTVARIABLE=hellohelloheloo
# ...
# Here put all the variables that will be marked for export
# and that will be available from within test2 (and all other commands).
# If test2 modifies the variables, the modifications will never be
# seen in the present script!
set +a

./test2.sh

 # Here, even if test2 modifies TESTVARIABLE, you'll still have
 # TESTVARIABLE=hellohelloheloo

Observe that the specs only specify that with set -a the variable is marked for export. That is:

set -a
a=b
set +a
a=c
bash -c 'echo "$a"'

will echo c and not an empty line nor b (that is, set +a doesn't unmark for export, nor does it “save” the value of the assignment only for the exported environment). This is, of course, the most natural behavior.

Conclusion: using set -a/set +a can be less tedious than exporting manually all the variables. It is superior to sourcing the second script, as it will work for any command, not only the ones written in the same shell language.

curl -u username:password http://
curl -u username http://

From the documentation page:

-u, --user <user:password>

Specify the user name and password to use for server authentication. Overrides -n, --netrc and --netrc-optional.

If you simply specify the user name, curl will prompt for a password.

The user name and passwords are split up on the first colon, which makes it impossible to use a colon in the user name with this option. The password can, still.

When using Kerberos V5 with a Windows based server you should include the Windows domain name in the user name, in order for the server to succesfully obtain a Kerberos Ticket. If you don't then the initial authentication handshake may fail.

When using NTLM, the user name can be specified simply as the user name, without the domain, if there is a single domain and forest in your setup for example.

To specify the domain name use either Down-Level Logon Name or UPN (User Principal Name) formats. For example, EXAMPLE\user and [email protected] respectively.

If you use a Windows SSPI-enabled curl binary and perform Kerberos V5, Negotiate, NTLM or Digest authentication then you can tell curl to select the user name and password from your environment by specifying a single colon with this option: "-u :".

If this option is used several times, the last one will be used.

http://curl.haxx.se/docs/manpage.html#-u

Note that you do not need --basic flag as it is the default.

You probably want os.makedirs as it will create intermediate directories as well, if needed.

import os

#dir is not keyword
def makemydir(whatever):
  try:
    os.makedirs(whatever)
  except OSError:
    pass
  # let exception propagate if we just can't
  # cd into the specified directory
  os.chdir(whatever)

Adding to @LorenCK's answer, change

NavUtils.navigateUpFromSameTask(this);

to the code below if your activity can be initiated from another activity and this can become part of task started by some other app

Intent upIntent = NavUtils.getParentActivityIntent(this);
if (NavUtils.shouldUpRecreateTask(this, upIntent)) {
    TaskStackBuilder.create(this)
            .addNextIntentWithParentStack(upIntent)
            .startActivities();
} else {
    NavUtils.navigateUpTo(this, upIntent);
}

This will start a new task and start your Activity's parent Activity which you can define in Manifest like below of Min SDK version <= 15

<meta-data
        android:name="android.support.PARENT_ACTIVITY"
        android:value="com.example.app_name.A" />

Or using parentActivityName if its > 15

Escape the percent sign \% to make it part of your comparison value.

I recently faced this same situation and found an easier inbuilt solution. I am sharing it here so that it might help other people looking for solution.

With OS X Yosemite, Apple has integrated the batch renaming capabilities directly into Finder. Details information is available here. I have copied the steps below as well,

Rename multiple items

1. Select the items, then Control-click one of them.

2. In the shortcut menu, select Rename Items.

3. In the pop-up menu below Rename Folder Items, choose to replace text in the names, add text to the names, or change the name format.

   • Replace text: Enter the text you want to remove in the Find field, then enter the text you want to add in the “Replace with” field.

   • Add text: Enter the text to you want to add in the field, then choose to add the text before or after the current name.

   • Format: Choose a name format for the files, then choose to put the index, counter, or date before or after the name. Enter a name in the Custom Format field, then enter the number you want to start with.

4. Click Rename.

If you have a common pattern in your files than you can use Replace text otherwise Add text would also do the job.

struct Rect
{
   Rect(int x1, int x2, int y1, int y2)
   : x1(x1), x2(x2), y1(y1), y2(y2)
   {
       assert(x1 < x2);
       assert(y1 < y2);
   }

   int x1, x2, y1, y2;
};

//some area of the r1 overlaps r2
bool overlap(const Rect &r1, const Rect &r2)
{
    return r1.x1 < r2.x2 && r2.x1 < r1.x2 &&
           r1.y1 < r2.y2 && r2.x1 < r1.y2;
}

//either the rectangles overlap or the edges touch
bool touch(const Rect &r1, const Rect &r2)
{
    return r1.x1 <= r2.x2 && r2.x1 <= r1.x2 &&
           r1.y1 <= r2.y2 && r2.x1 <= r1.y2;
}

They change it again. At this moment documentation does not fit actual situation.

Commonly all works as expected with one small difference. Login from Devices config now moves to Products -> Facebook Login.

So you need to:

• get your App id from headline,
• get Client Token from app Settings -> Advanced. There is also Native or desktop app? question/config. I turn it on.
• Add product (just click on Add product and then Get started on Facebook login. Move back to your app config, click to newly added Facebook login and you'll see your Login from Devices config.

This warning is issued due the security features, do not disable this feature.

It's just displayed once.

If it still appears after second connection, the problem is probably in writing to the known_hosts file. In this case you'll also get the following message:

Failed to add the host to the list of known hosts 

You may fix it by changing owner of changing the permissions of the file to be writable by your user.

sudo chown -v $USER ~/.ssh/known_hosts

The project JsonSubTypes implement a generic converter that handle this feature with the helps of attributes.

For the concrete sample provided here is how it works:

    [JsonConverter(typeof(JsonSubtypes))]
    [JsonSubtypes.KnownSubTypeWithProperty(typeof(Employee), "JobTitle")]
    [JsonSubtypes.KnownSubTypeWithProperty(typeof(Artist), "Skill")]
    public class Person
    {
        public string FirstName { get; set; }
        public string LastName { get; set; }
    }

    public class Employee : Person
    {
        public string Department { get; set; }
        public string JobTitle { get; set; }
    }

    public class Artist : Person
    {
        public string Skill { get; set; }
    }

    [TestMethod]
    public void Demo()
    {
        string json = "[{\"Department\":\"Department1\",\"JobTitle\":\"JobTitle1\",\"FirstName\":\"FirstName1\",\"LastName\":\"LastName1\"}," +
                      "{\"Department\":\"Department1\",\"JobTitle\":\"JobTitle1\",\"FirstName\":\"FirstName1\",\"LastName\":\"LastName1\"}," +
                      "{\"Skill\":\"Painter\",\"FirstName\":\"FirstName1\",\"LastName\":\"LastName1\"}]";


        var persons = JsonConvert.DeserializeObject<IReadOnlyCollection<Person>>(json);
        Assert.AreEqual("Painter", (persons.Last() as Artist)?.Skill);
    }

I got this, the only way I found to fix this was to update all of mingw-64 (I did this using pacman on msys2 for your information).

Yes, you should be able to do git reflog --no-abbrev and find the SHA1 for the commit at the tip of your deleted branch, then just git checkout [sha]. And once you're at that commit, you can just git checkout -b [branchname] to recreate the branch from there.

Credit to @Cascabel for this condensed/one-liner version and @Snowcrash for how to obtain the sha.

If you've just deleted the branch you'll see something like this in your terminal Deleted branch <your-branch> (was <sha>). Then just use that <sha> in this one-liner:

git checkout -b <your-branch> <sha>

You are looking for asort()

In SQL Server Management Studio (SSMS):

You can also right click your database in the Object Explorer and go to Properties. From there, go to Options. Scroll all the way down and set Restrict Access to SINGLE_USER. Change your database name, then go back in and set it back to MULTI_USER.

i also encounter that error once in a while, but when it does, it means that my branch is not up-to-date so i have to do git pull origin <current_branch>

Check for @ and . and then send an email for them to verify.

I still can't use my .name email address on 20% of the sites on the internet because someone screwed up their email validation, or because it predates the new addresses being valid.

This is for Charts.js 2.0:

The reason some of these are not working is because you should declare your options when you create your chart like so:

$(function () {
    var ctxLine = document.getElementById("myLineChart");
    var myLineChart = new Chart(ctxLine, {
        type: 'line',
        data: dataLine,
        options: {
            scales: {
                yAxes: [{
                    ticks: {
                        min: 0,
                        beginAtZero: true
                    }
                }]
            }
        }

    });
})

Documentation for this is here: http://www.chartjs.org/docs/#scales

FILE *f = fopen("file.txt", "w");
if (f == NULL)
{
    printf("Error opening file!\n");
    exit(1);
}

fprintf(f, "Some text: %s\n", text);

/* print integers and floats */
int i = 1;
float py = 3.1415927;
fprintf(f, "Integer: %d, float: %f\n", i, py);

/* printing single chatacters */
char c = 'A';
fprintf(f, "A character: %c\n", c);

I found the answer. IE stores passwords in two different locations based on the password type:

• Http-Auth: %APPDATA%\Microsoft\Credentials, in encrypted files
• Form-based: HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\IntelliForms\Storage2, encrypted with the url

From a very good page on NirSoft.com:

Starting from version 7.0 of Internet Explorer, Microsoft completely changed the way that passwords are saved. In previous versions (4.0 - 6.0), all passwords were saved in a special location in the Registry known as the "Protected Storage". In version 7.0 of Internet Explorer, passwords are saved in different locations, depending on the type of password. Each type of passwords has some limitations in password recovery:

• AutoComplete Passwords: These passwords are saved in the following location in the Registry: HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\IntelliForms\Storage2 The passwords are encrypted with the URL of the Web sites that asked for the passwords, and thus they can only be recovered if the URLs are stored in the history file. If you clear the history file, IE PassView won't be able to recover the passwords until you visit again the Web sites that asked for the passwords. Alternatively, you can add a list of URLs of Web sites that requires user name/password into the Web sites file (see below).

• HTTP Authentication Passwords: These passwords are stored in the Credentials file under Documents and Settings\Application Data\Microsoft\Credentials, together with login passwords of LAN computers and other passwords. Due to security limitations, IE PassView can recover these passwords only if you have administrator rights.

In my particular case it answers the question of where; and I decided that I don't want to duplicate that. I'll continue to use CredRead/CredWrite, where the user can manage their passwords from within an established UI system in Windows.

1. Check the trees.config file which located in config folder... sometimes (I don't know why) this file became to be empty like someone delete the content inside... keep backup up of this file in your local pc then when this error appear - replace the server file with your local file. This is what i do when this error happened.

2. check the available space on the server. sometimes this is the problem.

Good luck.

Use the HLS Downloader Google Chrome extension to get the link to the M3U playlist. Its icon in the browser bar will show the number of playlists found on the current webpage. Clicking on the icon you can then see a list of the playlist link and then use the copy button next to a link to copy it.

Then use the youtube-dl program to download the file.

youtube-dl --all-subs -f mp4 -o "file-name-to-save-as.mp4" "https://link-from-Google_Chrome-HLS_Downloader_extension"

Explanation of command line options:

• -f mp4 = Output format mp4

• --all-subs = Download all subtitles

• -o "file-name-to-save-as.mp4" = Name of the file to save the video as.

• "https://link-from-Google_Chrome-HLS_Downloader_extension" = This is the link to the playlist you copied from the HLS Downloader extension.

If you use the same configuration options all the time for youtube-dl you may want to take a look at the configuration options for youtube-dl, as this can save you a lot of typing.

The HLS Downloader extension is free and open source under the MIT license if you want to see the code it can be found on its project page on Github.

What about just defining multiple patterns? They might come from a config file containing known patterns, hard coded it reads like:

List<SimpleDateFormat> knownPatterns = new ArrayList<SimpleDateFormat>();
knownPatterns.add(new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss'Z'"));
knownPatterns.add(new SimpleDateFormat("yyyy-MM-dd'T'HH:mm.ss'Z'"));
knownPatterns.add(new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss"));
knownPatterns.add(new SimpleDateFormat("yyyy-MM-dd' 'HH:mm:ss"));
knownPatterns.add(new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ssXXX"));

for (SimpleDateFormat pattern : knownPatterns) {
    try {
        // Take a try
        return new Date(pattern.parse(candidate).getTime());

    } catch (ParseException pe) {
        // Loop on
    }
}
System.err.println("No known Date format found: " + candidate);
return null;

One of the way would be using NumberFormat.

NumberFormat formatter = new DecimalFormat("#0.00");     
System.out.println(formatter.format(4.0));

Output:

4.00

I was able to get this to work by using the Invoke-Expression cmdlet.

Invoke-Expression "& `"$scriptPath`" test -r $number -b $testNumber -f $FileVersion -a $ApplicationID"

I had exactly same problem (on OS X Maverics 10.9.1 with SQLite3 3.7.13, but I don't think SQLite is related to the cause). I tried to import csv data saved from MS Excel 2011, which btw. uses ';' as columns separator. I found out that csv file from Excel still uses newline character from Mac OS 9 times, changing it to unix newline solved the problem. AFAIR BBEdit has a command for this, as well as Sublime Text 2.

You can create a data.sql file in your src/main/resources folder and it will be automatically executed on startup. In this file you can add some insert statements, eg.:

INSERT INTO users (username, firstname, lastname) VALUES
  ('lala', 'lala', 'lala'),
  ('lolo', 'lolo', 'lolo');

Similarly, you can create a schema.sql file (or schema-h2.sql) as well to create your schema:

CREATE TABLE task (
  id          INTEGER PRIMARY KEY,
  description VARCHAR(64) NOT NULL,
  completed   BIT NOT NULL);

Though normally you shouldn't have to do this since Spring boot already configures Hibernate to create your schema based on your entities for an in memory database. If you really want to use schema.sql you'll have to disable this feature by adding this to your application.properties:

spring.jpa.hibernate.ddl-auto=none

More information can be found at the documentation about Database initialization.

If you're using Spring boot 2, database initialization only works for embedded databases (H2, HSQLDB, ...). If you want to use it for other databases as well, you need to change the spring.datasource.initialization-mode property:

spring.datasource.initialization-mode=always

If you're using multiple database vendors, you can name your file data-h2.sql or data-mysql.sql depending on which database platform you want to use.

To make that work, you'll have to configure the spring.datasource.platform property though:

spring.datasource.platform=h2

strace sqlplus -L scott/tiger@orcl helps to find .tnsnames.ora file on /home/oracle to find the file it takes instead of $ORACLE_HOME/network/admin/tnsnames.ora file. Thanks for the posting.

Regarding errors similar to

[11-May-2017 19:19:13 America/Chicago] PHP Warning: file_get_contents(): SSL operation failed with code 1. OpenSSL Error messages: error:14090086:SSL routines:ssl3_get_server_certificate:certificate verify failed

Have you checked the permissions of the cert and directories referenced by openssl?

You can do this

var_dump(openssl_get_cert_locations());

To get something similar to this

array(8) {
  ["default_cert_file"]=>
  string(21) "/usr/lib/ssl/cert.pem"
  ["default_cert_file_env"]=>
  string(13) "SSL_CERT_FILE"
  ["default_cert_dir"]=>
  string(18) "/usr/lib/ssl/certs"
  ["default_cert_dir_env"]=>
  string(12) "SSL_CERT_DIR"
  ["default_private_dir"]=>
  string(20) "/usr/lib/ssl/private"
  ["default_default_cert_area"]=>
  string(12) "/usr/lib/ssl"
  ["ini_cafile"]=>
  string(0) ""
  ["ini_capath"]=>
  string(0) ""
}

This issue frustrated me for a while, until I realized that my "certs" folder had 700 permissions, when it should have had 755 permissions. Remember, this is not the folder for keys but certificates. I recommend reading this this link on ssl permissions.

Once I did

chmod 755 certs

The problem was fixed, at least for me anyway.

As you might know android Software keyboard will be visible only when there is a possible event of typing. In other words Keyboard get visible only when EditText is focused. that means you can get weather the Keyboard is visible or not by using OnFocusChangeListener.

//Declare this Globally

public boolean isKeyBoardVisible = false;

//In OnCreate *[For Activity]*, OnCreateView *[For Fragment]*

text_send.setOnFocusChangeListener(new View.OnFocusChangeListener() {

    @Override
    public void onFocusChange(View v, boolean hasFocus) {
        if(hasFocus)
            isKeyBoardVisible = true;
        else
            isKeyBoardVisible = false;
    }
});

Now you can use isKeyBoardVisible variable anywhere in the class to get weather the keyboard is Open or Not. It worked well for me.

Note: This process doesn't work when the Keyboard is opened programmatically using InputMethodManager because that doesn't invoke OnFocusChangeListener.

I hope this example helps. You ca use the curly braces to make sure you've got everything enclosed in the switcher changer guy (sorry don't know the technical term but the term that precedes the = sign that changes what happens). I think of switch as a more controlled bunch of if () {} else {} statements.

Each time the switch function is the same but the command we supply changes.

do.this <- "T1"

switch(do.this,
    T1={X <- t(mtcars)
        colSums(mtcars)%*%X

    T2={X <- colMeans(mtcars)
        outer(X, X)
    },
    stop("Enter something that switches me!")
)

Here it is inside a function:

FUN <- function(df, do.this){
    switch(do.this,
        T1={X <- t(df)
            P <- colSums(df)%*%X
        },
        T2={X <- colMeans(df)
            P <- outer(X, X)
        },
        stop("Enter something that switches me!")
    )
    return(P)
}

FUN(mtcars, "T1")
FUN(mtcars, "T2")
FUN(mtcars, "T3")

Just Add AjaxControlToolkit.dll to your Reference folder.

On your Project Solution

Right Click on Reference Folder  > Add Reference > browse  AjaxControlToolkit.dll .

Then build.

The following signature will do:

List<Email> findByEmailIdInAndPincodeIn(List<String> emails, List<String> pinCodes);

Spring Data JPA supports a large number of keywords to build a query. IN and AND are among them.

This will happen if you are making selection in code as;

   mSpinner.setSelection(0);

Instead of above statement use

   mSpinner.setSelection(0,false);//just simply do not animate it.

Edit: This method doesn't work for Mi Android Version Mi UI.

This issue got fixed:

Please install the m2e connector for mavenarchiver plugin 0.17.3 from https://download.eclipse.org/m2e-wtp/releases/1.4/

obsolete answer

A less profound change than a downgrade from Spring Boot 2.1.5.RELEASE to 2.1.4.RELEASE would be downgrading only the affected Maven JAR Plugin from 3.1.2 to 3.1.1 as long as this bug exists:

<properties>
    <!-- ... -->
    <maven-jar-plugin.version>3.1.1</maven-jar-plugin.version>
</properties>

I go against convention here. I don't like typedef's to base types. I think it's a useless indirection that removes value.

1. When I see the base type in your source I will instantly understand it. If it's a typedef I have to look it up to see what I'm really dealing with.
2. When porting to another compiler or adding another library their set of typedefs may conflict and cause issues that are difficult to debug. I just got done dealing with this in fact. In one library boolean was typedef'ed to int, and in mingw/gcc it's typedef'ed to a char.

Use cursors.

A cursor can be thought of like a buffered reader, when reading through a document. If you think of each row as a line in a document, then you would read the next line, perform your operations, and then advance the cursor.

try this code to delete all data from a table..

String selectQuery = "DELETE FROM table_name ";
Cursor cursor = data1.getReadableDatabase().rawQuery(selectQuery, null);

schema : database : table :: floor plan : house : room

If you want the MIME type for a file, you can use the following code:

- (NSString *)mimeTypeForPath:(NSString *)path
{
    // get a mime type for an extension using MobileCoreServices.framework

    CFStringRef extension = (__bridge CFStringRef)[path pathExtension];
    CFStringRef UTI = UTTypeCreatePreferredIdentifierForTag(kUTTagClassFilenameExtension, extension, NULL);
    assert(UTI != NULL);

    NSString *mimetype = CFBridgingRelease(UTTypeCopyPreferredTagWithClass(UTI, kUTTagClassMIMEType));
    assert(mimetype != NULL);

    CFRelease(UTI);

    return mimetype;
}

In the case of a ZIP file, this will return application/zip.

Basically there are 4 ways to embed HTML into a web page:

• <iframe> An iframe's content lives entirely in a separate context than your page. While that's mostly a great feature and it's the most compatible among browser versions, it creates additional challenges (shrink wrapping the size of the frame to its content is tough, insanely frustrating to script into/out of, nearly impossible to style).
• AJAX. As the solutions shown here prove, you can use the XMLHttpRequest object to retrieve data and inject it to your page. It is not ideal because it depends on scripting techniques, thus making the execution slower and more complex, among other drawbacks.
• Hacks. Few mentioned in this question and not very reliable.

• HTML5 Web Components. HTML Imports, part of the Web Components, allows to bundle HTML documents in other HTML documents. That includes HTML, CSS, JavaScript or anything else an .html file can contain. This makes it a great solution with many interesting use cases: split an app into bundled components that you can distribute as building blocks, better manage dependencies to avoid redundancy, code organization, etc. Here is a trivial example:

  <!-- Resources on other origins must be CORS-enabled. -->
  <link rel="import" href="http://example.com/elements.html">
  

Native compatibility is still an issue, but you can use a polyfill to make it work in evergreen browsers Today.

I know it's an old question. but I faced this problem after updating to Android Studio 3.0. I solved it by deleting app.iml file inside my app module and then Invalidate Caches / Restart.

I'm late to the game here, but another approach could be:

1) create a branch from the tag ($ git checkout -b [new branch name] [tag name])

2) create a pull-request to merge with your new branch into the destination branch

As far as I know, there isn't any better way in terms of working with Reflection library in a smarter way. However, you could use LINQ to make the code a bit nicer:

var props = from p in t.GetProperties()
            let attrs = p.GetCustomAttributes(typeof(MyAttribute), true)
            where attrs.Length != 0 select p;

// Do something with the properties in 'props'

I believe this helps you to structure the code in a more readable fashion.

1. Right click your Project > Properties > Java Build Path > Libraries

2. Remove the file with red "X" (something like JRE...)

3. Add Library

That's how I solved my problem.

The most complete, concise definition of false I've come across is:

Anything that stringifies to the empty string or the string 0 is false. Everything else is true.

Therefore, the following values are false:

• The empty string
• Numerical value zero
• An undefined value
• An object with an overloaded boolean operator that evaluates one of the above.
• A magical variable that evaluates to one of the above on fetch.

Keep in mind that an empty list literal evaluates to an undefined value in scalar context, so it evaluates to something false.

A note on "true zeroes"

While numbers that stringify to 0 are false, strings that numify to zero aren't necessarily. The only false strings are 0 and the empty string. Any other string, even if it numifies to zero, is true.

The following are strings that are true as a boolean and zero as a number:

• Without a warning:
  • "0.0"
  • "0E0"
  • "00"
  • "+0"
  • "-0"
  • " 0"
  • "0\n"
  • ".0"
  • "0."
  • "0 but true"
  • "\t00"
  • "\n0e1"
  • "+0.e-9"
• With a warning:
  • Any string for which Scalar::Util::looks_like_number returns false. (e.g. "abc")

You can use FileReader to read the Blob as an ArrayBuffer.

Here's a short example:

var arrayBuffer;
var fileReader = new FileReader();
fileReader.onload = function(event) {
    arrayBuffer = event.target.result;
};
fileReader.readAsArrayBuffer(blob);

Here's a longer example:

// ArrayBuffer -> Blob
var uint8Array  = new Uint8Array([1, 2, 3]);
var arrayBuffer = uint8Array.buffer;
var blob        = new Blob([arrayBuffer]);

// Blob -> ArrayBuffer
var uint8ArrayNew  = null;
var arrayBufferNew = null;
var fileReader     = new FileReader();
fileReader.onload  = function(event) {
    arrayBufferNew = event.target.result;
    uint8ArrayNew  = new Uint8Array(arrayBufferNew);

    // warn if read values are not the same as the original values
    // arrayEqual from: http://stackoverflow.com/questions/3115982/how-to-check-javascript-array-equals
    function arrayEqual(a, b) { return !(a<b || b<a); };
    if (arrayBufferNew.byteLength !== arrayBuffer.byteLength) // should be 3
        console.warn("ArrayBuffer byteLength does not match");
    if (arrayEqual(uint8ArrayNew, uint8Array) !== true) // should be [1,2,3]
        console.warn("Uint8Array does not match");
};
fileReader.readAsArrayBuffer(blob);
fileReader.result; // also accessible this way once the blob has been read

This was tested out in the console of Chrome 27—69, Firefox 20—60, and Safari 6—11.

Here's also a live demonstration which you can play with: https://jsfiddle.net/potatosalad/FbaM6/

Update 2018-06-23: Thanks to Klaus Klein for the tip about event.target.result versus this.result

try putting a delay on the last color fade.

What are valid values for the id attribute in HTML?
ID's cannot start with digits!!!

Instead of creating a new route for that, you could just redirect to your controller/action and pass the information via querystring. For instance:

protected void Application_Error(object sender, EventArgs e) {
  Exception exception = Server.GetLastError();
  Response.Clear();

  HttpException httpException = exception as HttpException;

  if (httpException != null) {
    string action;

    switch (httpException.GetHttpCode()) {
      case 404:
        // page not found
        action = "HttpError404";
        break;
      case 500:
        // server error
        action = "HttpError500";
        break;
      default:
        action = "General";
        break;
      }

      // clear error on server
      Server.ClearError();

      Response.Redirect(String.Format("~/Error/{0}/?message={1}", action, exception.Message));
    }

Then your controller will receive whatever you want:

// GET: /Error/HttpError404
public ActionResult HttpError404(string message) {
   return View("SomeView", message);
}

There are some tradeoffs with your approach. Be very very careful with looping in this kind of error handling. Other thing is that since you are going through the asp.net pipeline to handle a 404, you will create a session object for all those hits. This can be an issue (performance) for heavily used systems.

Using latest Jenkins version 2.7.4 which is also having a bug for existing jobs.

1. Add new JDKs through Manage Jenkins -> Global Tool Configuration -> JDK ** If you edit current job then JDK dropdown is not showing (bug)

2. Hit http://your_jenkin_server:8080/restart and restart the server

3. Re-configure job

Now, you should see JDK dropdown in "job name" -> Configure in Jenkins web ui. It will list all JDKs available in Jenkins configuration.

In this case you can use display:inline or inline-block.

Example:

img.likeordisklike {display:inline;vertical-align:middle;  }_x000D_
h4.liketext { color:#F00; display:inline;vertical-align:top;padding-left:10px; }

<img class='likeordislike' src='design/like.png'/><h4 class='liketext'>$likes</h4>_x000D_
<img class='likeordislike' src='design/dislike.png'/><h4 class='liketext'>$dislikes</h4>

Don't use float:left because again need to write one more clear line and its old method also..

Execute VSWinExpress /resetuserdata, located in C:\Program Files (x86)\Microsoft Visual Studio 12.0, to reset the user credentials for Visual Studio 2013 Express.

Yes, go ahead and use it.

EventEmitter is a public, documented type in the final Angular Core API. Whether or not it is based on Observable is irrelevant; if its documented emit and subscribe methods suit what you need, then go ahead and use it.

As also stated in the docs:

Uses Rx.Observable but provides an adapter to make it work as specified here: https://github.com/jhusain/observable-spec

Once a reference implementation of the spec is available, switch to it.

So they wanted an Observable like object that behaved in a certain way, they implemented it, and made it public. If it were merely an internal Angular abstraction that shouldn't be used, they wouldn't have made it public.

There are plenty of times when it's useful to have an emitter which sends events of a specific type. If that's your use case, go for it. If/when a reference implementation of the spec they link to is available, it should be a drop-in replacement, just as with any other polyfill.

Just be sure that the generator you pass to the subscribe() function follows the linked spec. The returned object is guaranteed to have an unsubscribe method which should be called to free any references to the generator (this is currently an RxJs Subscription object but that is indeed an implementation detail which should not be depended on).

export class MyServiceEvent {
    message: string;
    eventId: number;
}

export class MyService {
    public onChange: EventEmitter<MyServiceEvent> = new EventEmitter<MyServiceEvent>();

    public doSomething(message: string) {
        // do something, then...
        this.onChange.emit({message: message, eventId: 42});
    }
}

export class MyConsumer {
    private _serviceSubscription;

    constructor(private service: MyService) {
        this._serviceSubscription = this.service.onChange.subscribe({
            next: (event: MyServiceEvent) => {
                console.log(`Received message #${event.eventId}: ${event.message}`);
            }
        })
    }

    public consume() {
        // do some stuff, then later...

        this.cleanup();
    }

    private cleanup() {
        this._serviceSubscription.unsubscribe();
    }
}

All of the strongly-worded doom and gloom predictions seem to stem from a single Stack Overflow comment from a single developer on a pre-release version of Angular 2.

Generally you shouldn't rely on system properties to configure a webapp - they may be used to configure the container (e.g. Tomcat) but not an application running inside tomcat.

cliff.meyers has already mentioned the way you should rather use for your webapplication. That's the standard way, that also fits your question of being configurable through context.xml or server.xml means.

That said, should you really need system properties or other jvm options (like max memory settings) in tomcat, you should create a file named "bin/setenv.sh" or "bin/setenv.bat". These files do not exist in the standard archive that you download, but if they are present, the content is executed during startup (if you start tomcat via startup.sh/startup.bat). This is a nice way to separate your own settings from the standard tomcat settings and makes updates so much easier. No need to tweak startup.sh or catalina.sh.

(If you execute tomcat as windows servive, you usually use tomcat5w.exe, tomcat6w.exe etc. to configure the registry settings for the service.)

EDIT: Also, another possibility is to go for JNDI Resources.

django is smart enough. Actually we don't need to define oneToMany field. It will be automatically generated by django for you :-). We only need to define foreignKey in related table. In other words, we only need to define ManyToOne relation by using foreignKey.

class Car(models.Model):
    // wheels = models.oneToMany() to get wheels of this car [**it is not required to define**].


class Wheel(models.Model):
    car = models.ForeignKey(Car, on_delete=models.CASCADE)  

if we want to get the list of wheels of particular car. we will use python's auto generated object wheel_set. For car c you will use c.wheel_set.all()

If for example, it is an Ubuntu, after installing the packages:

$sudo apt install golang -y

Just add the following lines to ~/.bashrc (Of your user)

export GOROOT=/usr/lib/go
export GOPATH=$HOME/go
export PATH=$PATH:$GOROOT/bin:$GOPATH/bin

Try to use the following code. It will help you in full or more.

1. A .xml file designed to use this code to set background color:

   android:background="#000000"
   

   or

   android:background="#FFFFFF"
   

   

   Or you can set it programmatically as well.

2. Also you can use this code programmatically:

   image.setBackgroundDrawable(getResources().getDrawable(
       R.drawable.llabackground));
   

3. Also this code for setting the background color as well programmatically:

   image.setBackgroundColor(Color.parseColor("#FFFFFF"));
   

4. This code for the same programmatically:

   image.setBackgroundColor(getResources().getColor(Color.WHITE));
   

The color depends on your choice of which color you want to use for transparent. Mostly use a white or #FFFFFF color.

Regarding R.drawable.llabackground: This line of code is for your style of the background, like something special or different for your purpose. You can also use this.

You can use the opt(int) method and use a classical for loop.

<input type="text" required="true" value="" readonly>

Not the.

<input type="text" required="true" value="" readonly="true">

Yes you can start with the Wikipedia article explaining the Big O notation, which in a nutshell is a way of describing the "efficiency" (upper bound of complexity) of different type of algorithms. Or you can look at an earlier answer where this is explained in simple english

I couldn't hide the separator on a specific cell except using the following workaround

- (void)layoutSubviews {
    [super layoutSubviews];
    [self hideCellSeparator];
}

- (void)hideCellSeparator {
    for (UIView *view in  self.subviews) {
        if (![view isKindOfClass:[UIControl class]]) {
            [view removeFromSuperview];

Do not forget to access iframe after it is loaded. Old but reliable way without jQuery:

<iframe src="samedomain.com/page.htm" id="iframe" onload="access()"></iframe>

<script>
function access() {
   var iframe = document.getElementById("iframe");
   var innerDoc = iframe.contentDocument || iframe.contentWindow.document;
   console.log(innerDoc.body);
}
</script>

None of the answers above works for me. The only (let's say) solution has been to change the first TextView in a disabled EditText that receives focus and then add

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

in the onCreate callback to prevent keyboard to be shown. Now my first EditText looks like a TextView but can get the initial focus, finally.

You only need these CSS properties in .container class of Bootstrap and you can put inside him the normal grid system without someone content of the container will be out of him (without scroll-x in the viewport).

HTML:

<div class="container">
    <div class="row">
        <div class="col-xs-12">
            Your content here!
            ...    
        </div>
    </div>
    ... more rows
</div>

CSS:

/* Bootstrap custom */
.container{
    padding-left: 0rem;
    padding-right: 0rem;
    overflow: hidden;
}

I had this for MapActivity. Builds in Eclipse gets NoClassDefFound in debugger.

Forgot to add library to manifest, inside <Application>...</Application> element

<uses-library android:name="com.google.android.maps" />

You'd first wanna make sure you have the JSDT installed.

Next thing is to install some dedicated tools for the job, so check out AngularJS Eclipse Tools. The AngularJS Eclipse Templates might be of help, too, and here's a visual guide written for it to get you started.

Also see the AngularJS Eclipse getting started page.

Since this answer had been posted, the AngularJS Eclipse plugin was released, as other answers stated. You might wanna check it out first.

int numberOfSpaces = 3;
String space = String.format("%"+ numberOfSpaces +"s", " ");

I'm not sure if I understand your question correctly. It is a bit unclear. However, what might be confusing you is the following:

1. When passing by reference, a reference to the same object is passed to the function being called. Any changes to the object will be reflected in the original object and hence the caller will see it.

2. When passing by value, the copy constructor will be called. The default copy constructor will only do a shallow copy, hence, if the called function modifies an integer in the object, this will not be seen by the calling function, but if the function changes a data structure pointed to by a pointer within the object, then this will be seen by the caller due to the shallow copy.

I might have mis-understood your question, but I thought I would give it a stab anyway.

I was able to use nginx to handle the 301 redirect to the aws signin page.

Go to your nginx conf folder (in my case it's /etc/nginx/sites-available in which I create a symlink to /etc/nginx/sites-enabled for the enabled conf files).

Then add a redirect path

server {
  listen 80;
  server_name aws.example.com;
  return 301 https://myaccount.signin.aws.amazon.com/console;
}

If you are using nginx, you will most likely have additional server blocks (virtualhosts in apache terminology) to handle your zone apex (example.com) or however you have it setup. Make sure that you have one of them set to be your default server.

server {
  listen 80 default_server;
  server_name example.com;
  # rest of config ...
}

In Route 53, add an A record for aws.example.com and set the value to the same IP used for your zone apex.

Try this to redirect cout to file.

#include <iostream>
#include <fstream>

int main()
{
    /** backup cout buffer and redirect to out.txt **/
    std::ofstream out("out.txt");

    auto *coutbuf = std::cout.rdbuf();
    std::cout.rdbuf(out.rdbuf());

    std::cout << "This will be redirected to file out.txt" << std::endl;

    /** reset cout buffer **/
    std::cout.rdbuf(coutbuf);

    std::cout << "This will be printed on console" << std::endl;

    return 0;
}

Andrea solution is absolutely right, I will just write another implementation based on the same idea. If you took a look at the THREE.ImageUtils.loadTexture() source you will find it uses the javascript Image object. The $(window).load event is fired after all Images are loaded ! so at that event we can render our scene with the textures already loaded...

• CoffeeScript

  $(document).ready ->
  
      material = new THREE.MeshLambertMaterial(map: THREE.ImageUtils.loadTexture("crate.gif"))
  
      sphere   = new THREE.Mesh(new THREE.SphereGeometry(radius, segments, rings), material)
  
      $(window).load ->
          renderer.render scene, camera
  

• JavaScript

  $(document).ready(function() {
  
      material = new THREE.MeshLambertMaterial({ map: THREE.ImageUtils.loadTexture("crate.gif") });
  
      sphere = new THREE.Mesh(new THREE.SphereGeometry(radius, segments, rings), material);
  
      $(window).load(function() {
          renderer.render(scene, camera);
      });
  });
  

Thanks...

I'd like to add something that hasn't been pointed out. Java doesn't take into account the values you have given the variables (2 and 3) in...

short a = 2; short b = 3; short c = a + b;

So as far as Java knows, you could done this...

short a = 32767; short b = 32767; short c = a + b;

Which would be outside the range of short, it autoboxes the result to an int becuase it's "possible" that the result will be more than a short but not more than an int. Int was chosen as a "default" because basically most people wont be hard coding values above 2,147,483,647 or below -2,147,483,648

After rollback check your tables , be sure of deletion.

If there is a problem delete tables manually from database application like phpmyadmin ( I'm using sequel pro for mac ).

Correct your down methods in the migration .

Note : Do rollback then migrate .. Don't use migrate:refresh to notice where is the error been .

After that you may test with new db for testing. to detect where is the problem.

If you use pip version of tensorflow, it means it's already compiled and you are just installing it. Basically you install tensorflow-gpu, but when you download it from repository and trying to build, you should build it with CPU AVX support. If you ignore it, you will get the warning every time when you run on cpu.

You can try the following library: Android Screenshot Library (ASL) enables to programmatically capture screenshots from Android devices without requirement of having root access privileges. Instead, ASL utilizes a native service running in the background, started via the Android Debug Bridge (ADB) once per device boot.

I would say that you should only expect users to have a monitor with 800x600 resolution. The Canadian government has standards that list this as one of the requirements. Although that may seem low to somebody with a fancy widescreen monitor, remember that not everybody has a nice monitor. I still know a lot of people running at 1024x768. And it's not at all uncommon to run into someone who's running in 800x600, especially in cheap web cafes while travelling. Also, it's nice to have to make your browser window full screen if you don't want to. You can make the site wider on wider monitors, but don't make the user scroll horizontally. Ever. Another advantage of supporting lower resolutions is that your site will work on mobile phones and Nintendo Wii's a lot easier.

A note on your at least 1280 wide, I would have to say that's way overboard. Most 17 and even my 19 inch non widescreen monitors only support a maximum resolution of 1280x1024. And the 14 inch widescreen laptop I'm typing on right now is only 1280 pixels across. I would say that the largest minimum resolution you should strive for is 1024x768, but 800x600 would be ideal.

cron already sends the standard output and standard error of every job it runs by mail to the owner of the cron job.

You can use MAILTO=recipient in the crontab file to have the emails sent to a different account.

For this to work, you need to have mail working properly. Delivering to a local mailbox is usually not a problem (in fact, chances are ls -l "$MAIL" will reveal that you have already been receiving some) but getting it off the box and out onto the internet requires the MTA (Postfix, Sendmail, what have you) to be properly configured to connect to the world.

If there is no output, no email will be generated.

A common arrangement is to redirect output to a file, in which case of course the cron daemon won't see the job return any output. A variant is to redirect standard output to a file (or write the script so it never prints anything - perhaps it stores results in a database instead, or performs maintenance tasks which simply don't output anything?) and only receive an email if there is an error message.

To redirect both output streams, the syntax is

42 17 * * * script >>stdout.log 2>>stderr.log

Notice how we append (double >>) instead of overwrite, so that any previous job's output is not replaced by the next one's.

As suggested in many answers here, you can have both output streams be sent to a single file; replace the second redirection with 2>&1 to say "standard error should go wherever standard output is going". (But I don't particularly endorse this practice. It mainly makes sense if you don't really expect anything on standard output, but may have overlooked something, perhaps coming from an external tool which is called from your script.)

cron jobs run in your home directory, so any relative file names should be relative to that. If you want to write outside of your home directory, you obviously need to separately make sure you have write access to that destination file.

A common antipattern is to redirect everything to /dev/null (and then ask Stack Overflow to help you figure out what went wrong when something is not working; but we can't see the lost output, either!)

From within your script, make sure to keep regular output (actual results, ideally in machine-readable form) and diagnostics (usually formatted for a human reader) separate. In a shell script,

echo "$results"  # regular results go to stdout
echo "$0: something went wrong" >&2

Some platforms (and e.g. GNU Awk) allow you to use the file name /dev/stderr for error messages, but this is not properly portable; in Perl, warn and die print to standard error; in Python, write to sys.stderr, or use logging; in Ruby, try $stderr.puts. Notice also how error messages should include the name of the script which produced the diagnostic message.

The structs testing.T and testing.B both have a .Log and .Logf method that sound to be what you are looking for. .Log and .Logf are similar to fmt.Print and fmt.Printf respectively.

See more details here: http://golang.org/pkg/testing/#pkg-index

fmt.X print statements do work inside tests, but you will find their output is probably not on screen where you expect to find it and, hence, why you should use the logging methods in testing.

If, as in your case, you want to see the logs for tests that are not failing, you have to provide go test the -v flag (v for verbosity). More details on testing flags can be found here: https://golang.org/cmd/go/#hdr-Testing_flags

It should be this:

if (myString!="-1")
{
//Do things
}

Your equals and exclamation are the wrong way round.

You can probably just use the true command:

if [ "$a" -ge 10 ]; then
    true
elif [ "$a" -le 5 ]; then
    echo "1"
else
    echo "2"
fi

An alternative, in your example case (but not necessarily everywhere) is to re-order your if/else:

if [ "$a" -le 5 ]; then
    echo "1"
elif [ "$a" -lt 10 ]; then
    echo "2"
fi

you can use ? at the end to skip one "\"

regex("\\\\?")

For a similar effect to form's target attribute, you can also use the formtarget attribute of input[type="submit]" or button[type="submit"].

From MDN:

...this attribute is a name or keyword indicating where to display the response that is received after submitting the form. This is a name of, or keyword for, a browsing context (for example, tab, window, or inline frame). If this attribute is specified, it overrides the target attribute of the elements's form owner. The following keywords have special meanings:

• _self: Load the response into the same browsing context as the current one. This value is the default if the attribute is not specified.
• _blank: Load the response into a new unnamed browsing context.
• _parent: Load the response into the parent browsing context of the current one. If there is no parent, this option behaves the same way as _self.
• _top: Load the response into the top-level browsing context (that is, the browsing context that is an ancestor of the current one, and has no parent). If there is no parent, this option behaves the same way as _self.

You can take the first string, replace all the @ with vs using str_replace, then explode on vs or vice versa.

It means the title argument is optional. So if you call the method with no arguments it will use a default value of "Error".

It's shorthand for writing:

if (!title) {
  title = "Error";
}

This kind of shorthand trick with boolean expressions is common in Perl too. With the expression:

a OR b

it evaluates to true if either a or b is true. So if a is true you don't need to check b at all. This is called short-circuit boolean evaluation so:

var title = title || "Error";

basically checks if title evaluates to false. If it does, it "returns" "Error", otherwise it returns title.

Wow! Mean this that you must learn a different programming language just to send two keys to the keyboard? There are simpler ways for you to achieve the same thing. :-)

The Batch file below is an example that start another program (cmd.exe in this case), send a command to it and then send an Up Arrow key, that cause to recover the last executed command. The Batch file is simple enough to be understand with no problems, so you may modify it to fit your needs.

@if (@CodeSection == @Batch) @then


@echo off

rem Use %SendKeys% to send keys to the keyboard buffer
set SendKeys=CScript //nologo //E:JScript "%~F0"

rem Start the other program in the same Window
start "" /B cmd

%SendKeys% "echo off{ENTER}"

set /P "=Wait and send a command: " < NUL
ping -n 5 -w 1 127.0.0.1 > NUL
%SendKeys% "echo Hello, world!{ENTER}"

set /P "=Wait and send an Up Arrow key: [" < NUL
ping -n 5 -w 1 127.0.0.1 > NUL
%SendKeys% "{UP}"

set /P "=] Wait and send an Enter key:" < NUL
ping -n 5 -w 1 127.0.0.1 > NUL
%SendKeys% "{ENTER}"

%SendKeys% "exit{ENTER}"

goto :EOF


@end


// JScript section

var WshShell = WScript.CreateObject("WScript.Shell");
WshShell.SendKeys(WScript.Arguments(0));

For a list of key names for SendKeys, see: http://msdn.microsoft.com/en-us/library/8c6yea83(v=vs.84).aspx

For example:

LEFT ARROW    {LEFT}
RIGHT ARROW   {RIGHT}

AFAIS, no one mentions of atomic reference.

Integer

public void swap(AtomicInteger a, AtomicInteger b){
    a.set(b.getAndSet(a.get()));
}

String

public void swap(AtomicReference<String> a, AtomicReference<String> b){
    a.set(b.getAndSet(a.get()));
}

This will do:

▢

It is ?
(known as a "WHITE SQUARE WITH ROUNDED CORNERS" on fileformat.info)

Or

◻

as ?
(known as a "WHITE MEDIUM SQUARE" on the same website)

Two with shadow:

❏
❑

as ? and ? . The difference between them is the shadows' shape. You can see it if you zoom in or if you print it out. (They are known as "LOWER RIGHT DROP-SHADOWED WHITE SQUARE" and "LOWER RIGHT SHADOWED WHITE SQUARE", respectively).

You can also use

☐

which is ?
(known as a "BALLOT BOX").

A sample is at http://jsfiddle.net/S2QCt/267/

(a note: on the Mac, ▢ is quite nice, because it is bigger and somewhat more elegant than ☐ On Windows, ☐ looks more standard, while ▢ is somewhat small.)

Python has the pickle module just for this kind of thing.

These functions are all that you need for saving and loading almost any object:

def save_obj(obj, name ):
    with open('obj/'+ name + '.pkl', 'wb') as f:
        pickle.dump(obj, f, pickle.HIGHEST_PROTOCOL)

def load_obj(name ):
    with open('obj/' + name + '.pkl', 'rb') as f:
        return pickle.load(f)

These functions assume that you have an obj folder in your current working directory, which will be used to store the objects.

Note that pickle.HIGHEST_PROTOCOL is a binary format, which could not be always convenient, but is good for performance. Protocol 0 is a text format.

In order to save collections of Python there is the shelve module.

Test castEnum = static_cast<Test>(a-1); will cast a to A. If you don't want to substruct 1, you can redefine the enum:

enum Test
{
    A:1, B
};

In this case Test castEnum = static_cast<Test>(a); could be used to cast a to A.

Just styling an input type="submit" like this worked for me:

.link-button { _x000D_
     background: none;_x000D_
     border: none;_x000D_
     color: #0066ff;_x000D_
     text-decoration: underline;_x000D_
     cursor: pointer; _x000D_
}

<input type="submit" class="link-button" />

Tested in Chrome, IE 7-9, Firefox

just this ?

<style name="Theme.AppCompat.Light.NoActionBar.FullScreen">
    <item name="android:windowFullscreen">true</item>
</style>

I think the others have answered your second question. As for the first, the "Hello World" of CUDA, I don't think there is a set standard, but personally, I'd recommend a parallel adder (i.e. a programme that sums N integers).

If you look the "reduction" example in the NVIDIA SDK, the superficially simple task can be extended to demonstrate numerous CUDA considerations such as coalesced reads, memory bank conflicts and loop unrolling.

See this presentation for more info:

http://www.gpgpu.org/sc2007/SC07_CUDA_5_Optimization_Harris.pdf

Linq.Min() / Linq.Max() approach:

DateTime date1 = new DateTime(2000,1,1);
DateTime date2 = new DateTime(2001,1,1);

DateTime minresult = new[] { date1,date2 }.Min();
DateTime maxresult = new[] { date1,date2 }.Max(); 

You could do:

select sum(counts) total_records from (
    select count(*) as counts
    from temptable
    group by column_1, column_2, column_3, column_4
) as tmp

Add following lines after finish(); in onDestroy():

android.os.Process.killProcess(android.os.Process.myPid());
super.onDestroy();

You can change directory using this command like : currently if you current working directoris c:\ drive the if you want to go to your D:\ drive then type this command

cd /d D:\

now your current working directory is D:\ drive so you want go to Java directory under Docs so type below command :

cd Docs\Java

note : d stands for drive

The problem is you defined myList from main.py, but subfile.py needs to use it. Here is a clean way to solve this problem: move all globals to a file, I call this file settings.py. This file is responsible for defining globals and initializing them:

# settings.py

def init():
    global myList
    myList = []

Next, your subfile can import globals:

# subfile.py

import settings

def stuff():
    settings.myList.append('hey')

Note that subfile does not call init()— that task belongs to main.py:

# main.py

import settings
import subfile

settings.init()          # Call only once
subfile.stuff()         # Do stuff with global var
print settings.myList[0] # Check the result

This way, you achieve your objective while avoid initializing global variables more than once.

I had similar issue while running emulator on mac os. After lot of struggle I found that I had incorrect sdk path set in .bash_profile. I have two installations of android and it was causing that issue. I managed to fix by matching ANDROID_SDK_ROOT path in .bash_profile with sdk I am using inside android studio.

To execute SomeClass.main(String [] args) from a deployed war file do:

Step 1: Write class SomeClass.java that has a main method method i.e. (public static void main(String[] args) {...})

Step 2: Deploy your WAR

Step 3: cd /usr/local/yourprojectsname/tomcat/webapps/projectName/WEB-INF

Step 4: java -cp "lib/jar1.jar:lib/jar2.jar: ... :lib/jarn.jar" com.mypackage.SomeClass arg1 arg2 ... arg3

Note1: (to see if the class SomeOtherClass.class is in /usr/tomcat/webapps/projectName/WEB-INF/lib)

run --> cd /usr/tomcat/webapps/projectName/WEB-INF/lib && find . -name '*.jar' | while read jarfile; do if jar tf "$jarfile" | grep SomeOtherClass.class; then echo "$jarfile"; fi; done

Note2: Write to standard out so you can see if your main actually works via print statements to the console. This is called a back door.

Note3: The comment above by Bozhidar Bozhanov seems correct

One simple way to do this is :
Go to Preferences -> Package Settings -> Your Theme Name -> Activation

In my case I installed Boxy Theme so the path will be
Preferences -> Package Settings -> Boxy Theme -> Activation

Then there will be a pop-up menu that will let you choose which type of the theme package you want to activate.
Use up and down arrow so choose then press enter or simply click the one you want to choose.

This is steps only applicable if the theme installed also customized the sublime text 3 sidebar.

Hope it help anyone!

As it has been pointed out, it depends on the type. For built-in data types, it is best to pass by value. Even some very small structures, such as a pair of ints can perform better by passing by value.

Here is an example, assume you have an integer value and you want pass it to another routine. If that value has been optimized to be stored in a register, then if you want to pass it be reference, it first must be stored in memory and then a pointer to that memory placed on the stack to perform the call. If it was being passed by value, all that is required is the register pushed onto the stack. (The details are a bit more complicated than that given different calling systems and CPUs).

If you are doing template programming, you are usually forced to always pass by const ref since you don't know the types being passed in. Passing penalties for passing something bad by value are much worse than the penalties of passing a built-in type by const ref.

Not sure why your current code isn't working but if you don't specifically need a date object this will work:

$first_date = strtotime($date_raw);
$second_date = strtotime('-1 day', $first_date);

print 'First Date ' . date('Y-m-d', $first_date);
print 'Next Date ' . date('Y-m-d', $second_date);

You can also use reduce method:

>>> myList = [3, 5, 4, 9]
>>> myTotal = reduce(lambda x,y: x+y, myList)
>>> myTotal
21

Furthermore, you can modify the lambda function to do other operations on your list.

You just need to do it in correct syntax. Let me give you a minimal example I just did with Python interactive shell:

>>> class MyNameClass():
...   def __init__(self, myname):
...       print myname
... 
>>> p1 = MyNameClass('John')
John

If you're using Maven 3, one option to work around this problem is to use the versions plugin http://www.mojohaus.org/versions-maven-plugin/

Specifically the commands,

mvn versions:set -DnewVersion=2.0-RELEASE
mvn versions:commit

This will update the parent and child poms to 2.0-RELEASE. You can run this as a build step before.

Unlike the release plugin, it doesn't try to talk to your source control

ianhanniballake is right. You can get all the functionality of Activity from FragmentActivity. In fact, FragmentActivity has more functionality.

Using FragmentActivity you can easily build tab and swap format. For each tab you can use different Fragment (Fragments are reusable). So for any FragmentActivity you can reuse the same Fragment.

Still you can use Activity for single pages like list down something and edit element of the list in next page.

Also remember to use Activity if you are using android.app.Fragment; use FragmentActivity if you are using android.support.v4.app.Fragment. Never attach a android.support.v4.app.Fragment to an android.app.Activity, as this will cause an exception to be thrown.

I think you would like to learn ajax first, try this: Ajax Tutorial

If you want to know how ajax works, it is not a good way to use jQuery directly. I support to learn the native way to send a ajax request to the server, see something about XMLHttpRequest:

var xhr = new XMLHttpReuqest();
xhr.open("GET", "http://some.com");

xhr.onreadystatechange = handler; // do something here...
xhr.send();
