Just a little addition if one wants to parse a space separated text file line by line.

read_file = function (path)
local file = io.open(path, "rb") 
if not file then return nil end

local lines = {}

for line in io.lines(path) do
    local words = {}
    for word in line:gmatch("%w+") do 
        table.insert(words, word) 
    end    
  table.insert(lines, words)
end

file:close()
return lines;
end

Be sure to checkout the branch you want to merge first and then pull it (so your local version matches the remote version).

Then checkout back to your branch you want to do the merge on and your git merge should work.

You cannot do so - the browser will not allow this because of security concerns. Although there are workarounds, the fact is that you shouldn't count on this working. The following Stack Overflow questions are relevant here:

• full path from file input using jquery
• How to get the file path from HTML input form in Firefox 3

In addition to these, the new HTML5 specification states that browsers will need to feed a Windows compatible fakepath into the input type="file" field, ostensibly for backward compatibility reasons.

• http://lists.whatwg.org/htdig.cgi/whatwg-whatwg.org/2009-March/018981.html
• The Mystery of c:\fakepath Unveiled

So trying to obtain the path is worse then useless in newer browsers - you'll actually get a fake one instead.

Update 2017 vibrate(interval) method is deprecated with Android-O(API 8.0)

To support all Android versions use this method.

// Vibrate for 150 milliseconds
private void shakeItBaby() {
    if (Build.VERSION.SDK_INT >= 26) {
        ((Vibrator) getSystemService(VIBRATOR_SERVICE)).vibrate(VibrationEffect.createOneShot(150, VibrationEffect.DEFAULT_AMPLITUDE));
    } else {
        ((Vibrator) getSystemService(VIBRATOR_SERVICE)).vibrate(150);
    }
}

Kotlin:

// Vibrate for 150 milliseconds
private fun shakeItBaby(context: Context) {
    if (Build.VERSION.SDK_INT >= 26) {
        (context.getSystemService(VIBRATOR_SERVICE) as Vibrator).vibrate(VibrationEffect.createOneShot(150, VibrationEffect.DEFAULT_AMPLITUDE))
    } else {
        (context.getSystemService(VIBRATOR_SERVICE) as Vibrator).vibrate(150)
    }
}

sys has some useful stuff:

What you want to do is prevent the default action of the click event. To do this, you will need to modify your script like this:

$(document).ready(function() {
  $('.galleryicon').live("click", function(e) {

    $('#mainImage').hide();
    $('#cakebox').css('background-image', "url('ajax-loader.gif')");
    var i = $('<img />').attr('src',this.href).load(function() {
        $('#mainImage').attr('src', i.attr('src'));
        $('#cakebox').css('background-image', 'none');
        $('#mainImage').fadeIn();
    });
    return false; 
    e.preventDefault();
   });
 });

So, you're adding an "e" that represents the event in the line $('.galleryicon').live("click", function(e) { and you're adding the line e.preventDefault();

Apart from following the optimizations mentioned in existing answers (not much helpful, was still painfully slow), doing below did the trick for me.

HP Notebook with 6 GM RAM and i5 processor I have, still android studio was terribly slow. After checking task manager for memory usage, noticed that there is a software called "HP Touchpoint Analytics Client" that was taking more than 1 GB memory. Found that it's a spyware installed by HP in Windows 10 after searching about it in Google.

Uninstalled a bunch of HP software which does nothing and slows down the system. Now, Android studio is considerably fast - Gradle build completes in less than 30 seconds when compared to more than 2 minutes before. Every keystroke would take 5 seconds to respond, now it is real time and performance is comparable with Eclipse.

This might be true for Laptops from other vendors as well like Dell, etc. HP really messed up the user experience with their spyware for Windows 10 users. Uninstall them, it will help Android studio and improves the overall laptop experience as well.

Hope this helps someone. Thanks.

You have two options. First, you could simply add a new column with the following:

ALTER TABLE {tableName} ADD COLUMN COLNew {type};

Second, and more complicatedly, but would actually put the column where you want it, would be to rename the table:

ALTER TABLE {tableName} RENAME TO TempOldTable;

Then create the new table with the missing column:

CREATE TABLE {tableName} (name TEXT, COLNew {type} DEFAULT {defaultValue}, qty INTEGER, rate REAL);

And populate it with the old data:

INSERT INTO {tableName} (name, qty, rate) SELECT name, qty, rate FROM TempOldTable;

Then delete the old table:

DROP TABLE TempOldTable;

I'd much prefer the second option, as it will allow you to completely rename everything if need be.

Using <meta http-equiv="X-UA-Compatible" content="IE=9">, IE9+ does support addEventListener by removing the "on" in the event name, like this:

 var btn1 = document.getElementById('btn1');
 btn1.addEventListener('mousedown', function() {
   console.log('mousedown');
 });

Most databases support != (popular programming languages) and <> (ANSI).

Databases that support both != and <>:

• MySQL 5.1: != and <>
• PostgreSQL 8.3: != and <>
• SQLite: != and <>
• Oracle 10g: != and <>
• Microsoft SQL Server 2000/2005/2008/2012/2016: != and <>
• IBM Informix Dynamic Server 10: != and <>
• InterBase/Firebird: != and <>
• Apache Derby 10.6: != and <>
• Sybase Adaptive Server Enterprise 11.0: != and <>

Databases that support the ANSI standard operator, exclusively:

• IBM DB2 UDB 9.5: <>
• Microsoft Access 2010: <>

I guess something like this would work:

Add System.ServiceProcess to your project references (It's on the .NET tab).

using System.ServiceProcess;

ServiceController sc = new ServiceController(SERVICENAME);

switch (sc.Status)
{
    case ServiceControllerStatus.Running:
        return "Running";
    case ServiceControllerStatus.Stopped:
        return "Stopped";
    case ServiceControllerStatus.Paused:
        return "Paused";
    case ServiceControllerStatus.StopPending:
        return "Stopping";
    case ServiceControllerStatus.StartPending:
        return "Starting";
    default:
        return "Status Changing";
}

Edit: There is also a method sc.WaitforStatus() that takes a desired status and a timeout, never used it but it may suit your needs.

Edit: Once you get the status, to get the status again you will need to call sc.Refresh() first.

Reference: ServiceController object in .NET.

Just using max-width: 0 in the display: table-cell element worked for me:

.table {_x000D_
  display: table;_x000D_
  width: 100%;_x000D_
}_x000D_
_x000D_
.table-cell {_x000D_
  display: table-cell;_x000D_
  max-width: 0px;_x000D_
  border: 1px solid gray;_x000D_
}

<div class="table">_x000D_
  <div class="table-cell">short</div>_x000D_
  <div class="table-cell">loooooong</div>_x000D_
  <div class="table-cell">Veeeeeeery loooooong</div>_x000D_
</div>

Check whether you have Not Null constraint in your table columns and you are not passes the value for that column while insert/Update operations. That Causes this exception in entity framework.

Instead of explicitly defining the path to the interpreter as in /usr/bin/bash/, by using the env command, the interpreter is searched for and launched from wherever it is first found. This has both upsides and downsides

try this

 $("#vinanghinguyen_images_bbocde").attr("value", ""); 

Using Guava's Maps class' utility methods to compute the difference of 2 maps you can do it in a single line, with a method signature which makes it more clear what you are trying to accomplish:

public static void main(final String[] args) {
    // Create some maps
    final Map<Integer, String> map1 = new HashMap<Integer, String>();
    map1.put(1, "Hello");
    map1.put(2, "There");
    final Map<Integer, String> map2 = new HashMap<Integer, String>();
    map2.put(2, "There");
    map2.put(3, "is");
    map2.put(4, "a");
    map2.put(5, "bird");

    // Add everything in map1 not in map2 to map2
    map2.putAll(Maps.difference(map1, map2).entriesOnlyOnLeft());
}

Your first block of code tells CLR to create a Thread (say. T) for you which is can be run as background (use thread pool threads when scheduling T ). In concise, you explicitly ask CLR to create a thread for you to do something and call Start() method on thread to start.

Your second block of code does the same but delegate (implicitly handover) the responsibility of creating thread (background- which again run in thread pool) and the starting thread through StartNew method in the Task Factory implementation.

This is a quick difference between given code blocks. Having said that, there are few detailed difference which you can google or see other answers from my fellow contributors.

You just make divs like this:

<div style="width:100px; height: 100px; border:1px solid; overflow:hidden; ">
    <br/>
    <div style="position:inherit; width: 200px; height:200px; background:yellow;">
        <br/>
        <div style="position:absolute; width: 500px; height:50px; background:Pink; z-index: 99;">
            <br/>
        </div>
    </div>
</div>

I hope this code will help you :)

In Swift 4.1 and Xcode 9.4.1

I have two apps 1)PageViewControllerExample and 2)DelegateExample. Now i want to open DelegateExample app with PageViewControllerExample app. When i click open button in PageViewControllerExample, DelegateExample app will be opened.

For this we need to make some changes in .plist files for both the apps.

Step 1

In DelegateExample app open .plist file and add URL Types and URL Schemes. Here we need to add our required name like "myapp".

Step 2

In PageViewControllerExample app open .plist file and add this code

<key>LSApplicationQueriesSchemes</key>
<array>
    <string>myapp</string>
</array>

Now we can open DelegateExample app when we click button in PageViewControllerExample.

//In PageViewControllerExample create IBAction
@IBAction func openapp(_ sender: UIButton) {

    let customURL = URL(string: "myapp://")
    if UIApplication.shared.canOpenURL(customURL!) {

        //let systemVersion = UIDevice.current.systemVersion//Get OS version
        //if Double(systemVersion)! >= 10.0 {//10 or above versions
            //print(systemVersion)
            //UIApplication.shared.open(customURL!, options: [:], completionHandler: nil)
        //} else {
            //UIApplication.shared.openURL(customURL!)
        //}

        //OR

        if #available(iOS 10.0, *) {
            UIApplication.shared.open(customURL!, options: [:], completionHandler: nil)
        } else {
            UIApplication.shared.openURL(customURL!)
        }
    } else {
         //Print alert here
    }
}

Steps to Make Sublime Text a Python IDE (Windows)

Tested successfully on Sublime Text 3. Assuming Sublime Text and package control are already installed . . .

1. Install Python (python.org) and pay attention to where it is installed or choose a simple location like the C drive, agreeing to remove character limit at the end of the installation.

2. Install package SublimeREPL (Cntrl + Shift + P, Package Control - Install Package, SublimeREPL, Enter).

3. Go to Preferences, Package Settings, SublimeREPL, Settings - User.

4. Paste in the following, updating the file path to your python installation folder, as needed. You may customize these and choose whatever syntax you like (last line) but I prefer my output in plain text.

   {
     "default_extend_env": {"PATH":"C:\\Program Files\\Python36\\"},
     "repl_view_settings": {
     "translate_tabs_to_spaces": false,
     "auto_indent": false,
     "smart_indent": false,
     "spell_check": false,
     "indent_subsequent_lines": false,
     "detect_indentation": false,
     "auto_complete": true,
     "line_numbers": false,
     "gutter": false,
     "syntax": "Packages/Text/Plain text.tmLanguage"
     }
   }
   

5. Save and close the file (SublimeREPL.sublime-settings).

6. Go to Tools, Build System, New Build System.

7. Replace all existing text with the following:

   {
   "target": "run_existing_window_command", 
   "id": "repl_python_run",
   "file": "config/Python/Main.sublime-menu"
   }
   

8. Cntrl + S or save as "C:\Users[username]\AppData\Roaming\Sublime Text 3\Packages\User\SublimeREPL-python.sublime-build" updating username or path as needed. This should be wherever your settings and builds are stored by Sublime Text.

9. Go to Tools, Build System, select SublimeREPL-python.

10. All done--now to test. Open or create a simple python file, having a *.py extension and save it wherever desired.

11. Make sure the file is open and selected in Sublime Text. Now, when you press Cntrl + B to build and run it, it will open another tab, titled "REPL [python]", executing and displaying the results of your python code.

If you would like to go a step further, I highly recommend making the follow changes, to allow Sublime to reload your executed python in the same window, when you press Cntrl+B (Build), instead of it opening a new tab each time:

Add the following line in the "repl_python_run" command in (Preferences, Browse Packages) SublimeREPL\config\Python\Main.sublime-menu, right before the "external_id": "python" argument:

"view_id": "*REPL* [python]",

and then to change the line:

if view.id() == view_id

into:

if view.name() == view_id

in SublimeREPL\sublimerepl.py.

Well, an application may have a lot of threads running in parallel. Some are run by you, the coder, some are run by framework classes (espacially if you are in a GUI environnement).

When a thread has finished its task, it exits and stops to exist. There ie nothing alarming in this and you should not care.

to me the shortest way to solve this problem is to use moment.js and solve this problem in just 2 lines.

var today = moment().format('YYYY-MM-DD');
$('#datePicker').val(today);

A great search engine for special characters that I recenetly found: amp-what?

You can even search by object name, like "arrow", "chess", etc...

int *a[], when used as a function parameter (but not in normal declarations), is a pointer to a pointer, not a pointer to an array (in normal declarations, it is an array of pointers). A pointer to an array looks like this:

int (*aptr)[N]

Where N is a particular positive integer (not a variable).

If you make your function a template, you can do it and you don't even need to pass the size of the array (because it is automatically deduced):

template<size_t SZ>
void generateArray(int (*aptr)[SZ])
{
    for (size_t i=0; i<SZ; ++i)
        (*aptr)[i] = rand() % 9;
}

int main()
{    
    int a[5];    
    generateArray(&a);
}

You could also take a reference:

template<size_t SZ>
void generateArray(int (&arr)[SZ])
{
    for (size_t i=0; i<SZ; ++i)
        arr[i] = rand() % 9;
}

int main()
{    
    int a[5];    
    generateArray(a);
}

In case of Select2 Version 4+

it has changed syntax and you need to write like this:

// clear all option
$('#select_with_blank_data').html('').select2({data: [{id: '', text: ''}]});

// clear and add new option
$("#select_with_data").html('').select2({data: [
 {id: '', text: ''},
 {id: '1', text: 'Facebook'},
 {id: '2', text: 'Youtube'},
 {id: '3', text: 'Instagram'},
 {id: '4', text: 'Pinterest'}]});



//  append option
$("#select_with_data").append('<option value="5">Twitter</option>');
$("#select_with_data").val('5');
$("#select_with_data").trigger('change');

# select columns containing 'spike'
df.filter(like='spike', axis=1)

You can also select by name, regular expression. Refer to: pandas.DataFrame.filter

Simply create an object of Base64 and use it to encode or decode, when using org.apache.commons.codec.binary.Base64 library

To Encode

Base64 ed=new Base64();

String encoded=new String(ed.encode("Hello".getBytes()));

Replace "Hello" with the text to be encoded in String Format.

To Decode

Base64 ed=new Base64();

String decoded=new String(ed.decode(encoded.getBytes()));

Here encoded is the String variable to be decoded

I ran in the same issue.

This is what worked for me:

Setting up Properties of Windows Authentication in IIS

NTLM has to be the topmost. Further Web.config modifications, make sure you already have or add if these do not exist:

<system.web>

  <authentication mode="Windows" />
  <identity impersonate="true"/>

</system.web>

 <!-- you need the following lines of code to bypass errors, concerning type of Application Pool (integrated pipeline or classic) -->

<system.webServer>
   <validation validateIntegratedModeConfiguration="false"/>
</system.webServer>

See below a legit explanation for the two nodes and

Difference between <system.web> and <system.webServer>?

And, of course , you get the username by

//I am using the following to get the index of the separator "\\" and remove the Domain name from the string
int indexOfSlashChar = HttpContext.Current.User.Identity.Name.IndexOf("\\"); 

loggedInWindowsUserName = HttpContext.Current.User.Identity.Name.Substring(indexOfSlashChar + 1);

The div tag is a block element, causing that behavior.

You should use a span element instead, which is inline.

If you really want to use div, add style="display: inline". (You can also put that in a CSS rule)

Tools --> Options --> Environment --> Fonts and Colors

There is also the InStrRev function which does the same type of thing, but starts searching from the end of the text to the beginning.

Per @rene's answer...

Dim pos As Integer
pos = InStrRev("find the comma, in the string", ",")

...would still return 15 to pos, but if the string has more than one of the search string, like the word "the", then:

Dim pos As Integer
pos = InStrRev("find the comma, in the string", "the")

...would return 20 to pos, instead of 6.

According to an article on Medium, this will work:

install --upgrade pandas==1.0.0rc0

Use:

select convert(nvarchar(10), CREATED_TS, 101)

or

select format(cast(CREATED_TS as date), 'MM/dd/yyyy') -- MySQL 3.23 and above

i do it like this cover button and the middle image that

<button><img src="foldername/imagename" width="30px" height= "30px"></button>

Try this..

select starttime,endtime, case
  when DATEDIFF(minute,starttime,endtime) < 60  then DATEDIFF(minute,starttime,endtime) 
  when DATEDIFF(minute,starttime,endtime) >= 60
  then '60,'+ cast( (cast(DATEDIFF(minute,starttime,endtime) as int )-60) as nvarchar(50) )
end from TestTable123416

All You need is DateDiff..

You can get its shape with:

print((df.count(), len(df.columns)))

This solution works with complex JSONs:

public Object toJSON(Object object) throws JSONException {
    if (object instanceof HashMap) {
        JSONObject json = new JSONObject();
        HashMap map = (HashMap) object;
        for (Object key : map.keySet()) {
            json.put(key.toString(), toJSON(map.get(key)));
        }
        return json;
    } else if (object instanceof Iterable) {
        JSONArray json = new JSONArray();
        for (Object value : ((Iterable) object)) {
            json.put(toJSON(value));
        }
        return json;
    }
    else {
        return object;
    }
}

What you could do is have the selected attribute on the <select> tag be an attribute of this.state that you set in the constructor. That way, the initial value you set (the default) and when the dropdown changes you need to change your state.

constructor(){
  this.state = {
    selectedId: selectedOptionId
  }
}

dropdownChanged(e){
  this.setState({selectedId: e.target.value});
}

render(){
  return(
    <select value={this.selectedId} onChange={this.dropdownChanged.bind(this)}>
      {option_id.map(id =>
        <option key={id} value={id}>{options[id].name}</option>
      )}
    </select>
  );
}

Confirmation dialog can implemented using AngularJS Material:

$mdDialog opens a dialog over the app to inform users about critical information or require them to make decisions. There are two approaches for setup: a simple promise API and regular object syntax.

Note: Git 2.6 (Q3/Q4 2015) will finally provide a more meaningful error message.

See commit ce11360 (29 Aug 2015) by Jeff King (peff).
^{(Merged by Junio C Hamano -- gitster -- in commit 699a0f3, 02 Sep 2015)}

log: diagnose empty HEAD more clearly

If you init or clone an empty repository, the initial message from running "git log" is not very friendly:

$ git init
Initialized empty Git repository in /home/peff/foo/.git/
$ git log
fatal: bad default revision 'HEAD'

Let's detect this situation and write a more friendly message:

$ git log
fatal: your current branch 'master' does not have any commits yet

We also detect the case that 'HEAD' points to a broken ref; this should be even less common, but is easy to see.
Note that we do not diagnose all possible cases. We rely on resolve_ref, which means we do not get information about complex cases. E.g., "--default master" would use dwim_ref to find "refs/heads/master", but we notice only that "master" does not exist.
Similarly, a complex sha1 expression like "--default HEAD^2" will not resolve as a ref.

But that's OK. We fall back to a generic error message in those cases, and they are unlikely to be used anyway.
Catching an empty or broken "HEAD" improves the common case, and the other cases are not regressed.

In addition to the other responses, it is important to point out that 'finally' has the right to override any exception/returned value by the try..catch block. For example, the following code returns 12:

public static int getMonthsInYear() {
    try {
        return 10;
    }
    finally {
        return 12;
    }
}

Similarly, the following method does not throw an exception:

public static int getMonthsInYear() {
    try {
        throw new RuntimeException();
    }
    finally {
        return 12;
    }
}

While the following method does throw it:

public static int getMonthsInYear() {
    try {
        return 12;          
    }
    finally {
        throw new RuntimeException();
    }
}

You can use reduce to loop the array and get the not duplicate values. Also uses an aux object to get the count of added values.

var aux = {};_x000D_
_x000D_
var newArray = ["X_row7", "X_row4", "X_row6", "X_row10", "X_row8", "X_row9", "X_row11", "X_row7", "X_row4", "X_row6", "X_row10", "X_row8", "X_row9", "X_row11", "X_row7", "X_row4", "X_row6", "X_row10", "X_row8", "X_row9", "X_row11", "X_row7", "X_row4", "X_row6", "X_row10", "X_row8", "X_row9", "X_row11", "X_row7", "X_row4", "X_row6", "X_row10", "X_row8", "X_row9", "X_row11", "X_row7", "X_row4", "X_row6", "X_row10", "X_row8", "X_row9", "X_row11"].reduce((tot, curr)=>{_x000D_
  if(!aux[curr]){_x000D_
    aux[curr] = 1;_x000D_
    tot.push(curr);_x000D_
  }_x000D_
  return tot;_x000D_
}, []);_x000D_
_x000D_
console.log(newArray);

I think you have putted e.preventDefault(); before ajax call that's why its prevent calling of that function and your Ajax call will not call.

So try to remove that e.prevent Default() before Ajax call and add it to the after Ajax call.

Use with=FALSE:

cols = paste("V", c(1,2,3,5), sep="")

dt[, !cols, with=FALSE]

I suggest going through the "Introduction to data.table" vignette.

Update: From v1.10.2 onwards, you can also do:

dt[, ..cols]

See the first NEWS item under v1.10.2 here for additional explanation.

You need pass DBNull.Value as a null parameter within SQLCommand, unless a default value is specified within stored procedure (if you are using stored procedure). The best approach is to assign DBNull.Value for any missing parameter before query execution, and following foreach will do the job.

foreach (SqlParameter parameter in sqlCmd.Parameters)
{
    if (parameter.Value == null)
    {
        parameter.Value = DBNull.Value;
    }
}

Otherwise change this line:

planIndexParameter.Value = (AgeItem.AgeIndex== null) ? DBNull.Value : AgeItem.AgeIndex;

As follows:

if (AgeItem.AgeIndex== null)
    planIndexParameter.Value = DBNull.Value;
else
    planIndexParameter.Value = AgeItem.AgeIndex;

Because you can't use different type of values in conditional statement, as DBNull and int are different from each other. Hope this will help.

If you need a diagonal border instead of a diagonal corner, you can stack 2 divs with each a pseudo element:

check $this->upload->initialize($config); this works fine for me

    $new_image_name = "imgName".time() . str_replace(str_split(' ()\\/,:*?"<>|'), '', 
    $_FILES['userfile']['name']);
    $config = array();
    $config['upload_path'] = './uploads/';

    $config['file_name'] = $new_image_name;
    $config['max_size']  = '0';
    $config['upload_path'] = './uploads/';
    $config['allowed_types'] = 'gif|jpg|png|mp4|jpeg';
    $config['file_name'] = url_title("imgsclogo");
    $config['max_size']      = '0';

The easiest way is to use PyHive.

To install you'll need these libraries:

pip install sasl
pip install thrift
pip install thrift-sasl
pip install PyHive

After installation, you can connect to Hive like this:

from pyhive import hive
conn = hive.Connection(host="YOUR_HIVE_HOST", port=PORT, username="YOU")

Now that you have the hive connection, you have options how to use it. You can just straight-up query:

cursor = conn.cursor()
cursor.execute("SELECT cool_stuff FROM hive_table")
for result in cursor.fetchall():
  use_result(result)

...or to use the connection to make a Pandas dataframe:

import pandas as pd
df = pd.read_sql("SELECT cool_stuff FROM hive_table", conn)

If you want to transpose a matrix like A = np.array([[1,2],[3,4]]), then you can simply use A.T, but for a vector like a = [1,2], a.T does not return a transpose! and you need to use a.reshape(-1, 1), as below

import numpy as np
a = np.array([1,2])
print('a.T not transposing Python!\n','a = ',a,'\n','a.T = ', a.T)
print('Transpose of vector a is: \n',a.reshape(-1, 1))

A = np.array([[1,2],[3,4]])
print('Transpose of matrix A is: \n',A.T)

It may be that it's not loading the template you expect. I added a new class that inherited from UpdateView - I thought it would automatically pick the template from what I named my class, but it actually loaded it based on the model property on the class, which resulted in another (wrong) template being loaded. Once I explicitly set template_name for the new class, it worked fine.

I faced the same issue, spent too much calories searching for the right fix until I decided to settle down with file reading:

Properties configProps = new Properties();
InputStream iStream = new ClassPathResource("myapp-test.properties").getInputStream();
InputStream iStream = getConfigFile();
configProps.load(iStream);

Try username = root and password is blank.

-webkit-transform is no more needed

ms already support rotation ( -ms-transform: rotate(-10deg); )

try this:

li a {
   ...

    -webkit-transform: rotate(-10deg);
    -moz-transform: rotate(-10deg);
    -o-transform: rotate(-10deg);
    -ms-transform: rotate(-10deg);
    -sand-transform: rotate(10deg);
    display: block;
    position: fixed;
    }

To answer your direct question, it is:

Range("A1").NumberFormat = "@"

Or

Cells(1,1).NumberFormat = "@"

However, I suggest making changing the format to what you actually want displayed. This allows you to retain the data type in the cell and easily use cell formulas to manipulate the data.

Just a simple contribution. If the class that we need to instance is in the same file, we can use something like this:

# Get class from globals and create an instance
m = globals()['our_class']()

# Get the function (from the instance) that we need to call
func = getattr(m, 'function_name')

# Call it
func()

For example:

class A:
    def __init__(self):
        pass

    def sampleFunc(self, arg):
        print('you called sampleFunc({})'.format(arg))

m = globals()['A']()
func = getattr(m, 'sampleFunc')
func('sample arg')

# Sample, all on one line
getattr(globals()['A'](), 'sampleFunc')('sample arg')

And, if not a class:

def sampleFunc(arg):
    print('you called sampleFunc({})'.format(arg))

globals()['sampleFunc']('sample arg')

The standard way of multiplying an m-by-n matrix by an n-by-p matrix has complexity O(mnp). If all of those are "n" to you, it's O(n^3), not O(n^2). EDIT: it will not be O(n^2) in the general case. But there are faster algorithms for particular types of matrices -- if you know more you may be able to do better.

Consider using String#format with proper format specifications (%d or %f) instead.

int value = 10;

textView.setText(String.format("%d",value));

This will handle fraction separator and locale specific digits properly

To detect whether two balls collide, just check whether the distance between their centers is less than two times the radius. To do a perfectly elastic collision between the balls, you only need to worry about the component of the velocity that is in the direction of the collision. The other component (tangent to the collision) will stay the same for both balls. You can get the collision components by creating a unit vector pointing in the direction from one ball to the other, then taking the dot product with the velocity vectors of the balls. You can then plug these components into a 1D perfectly elastic collision equation.

Wikipedia has a pretty good summary of the whole process. For balls of any mass, the new velocities can be calculated using the equations (where v1 and v2 are the velocities after the collision, and u1, u2 are from before):

If the balls have the same mass then the velocities are simply switched. Here's some code I wrote which does something similar:

void Simulation::collide(Storage::Iterator a, Storage::Iterator b)
{
    // Check whether there actually was a collision
    if (a == b)
        return;

    Vector collision = a.position() - b.position();
    double distance = collision.length();
    if (distance == 0.0) {              // hack to avoid div by zero
        collision = Vector(1.0, 0.0);
        distance = 1.0;
    }
    if (distance > 1.0)
        return;

    // Get the components of the velocity vectors which are parallel to the collision.
    // The perpendicular component remains the same for both fish
    collision = collision / distance;
    double aci = a.velocity().dot(collision);
    double bci = b.velocity().dot(collision);

    // Solve for the new velocities using the 1-dimensional elastic collision equations.
    // Turns out it's really simple when the masses are the same.
    double acf = bci;
    double bcf = aci;

    // Replace the collision velocity components with the new ones
    a.velocity() += (acf - aci) * collision;
    b.velocity() += (bcf - bci) * collision;
}

As for efficiency, Ryan Fox is right, you should consider dividing up the region into sections, then doing collision detection within each section. Keep in mind that balls can collide with other balls on the boundaries of a section, so this may make your code much more complicated. Efficiency probably won't matter until you have several hundred balls though. For bonus points, you can run each section on a different core, or split up the processing of collisions within each section.

Try to use the rack-cors gem. And add the header field in your Ajax call.

Just a poke, but here's another way to write FizzBuzz :) 100 rows is enough to show the WITH statement, I reckon.

;WITH t100 AS (
 SELECT n=number
 FROM master..spt_values
 WHERE type='P' and number between 1 and 100
)                
 SELECT
    ISNULL(NULLIF(
    CASE WHEN n % 3 = 0 THEN 'Fizz' Else '' END +
    CASE WHEN n % 5 = 0 THEN 'Buzz' Else '' END, ''), RIGHT(n,3))
 FROM t100

But the real power behind WITH (known as Common Table Expression http://msdn.microsoft.com/en-us/library/ms190766.aspx "CTE") in SQL Server 2005 and above is the Recursion, as below where the table is built up through iterations adding to the virtual-table each time.

;WITH t100 AS (
 SELECT n=1
 union all
 SELECT n+1
 FROM t100
 WHERE n < 100
)                
 SELECT
    ISNULL(NULLIF(
    CASE WHEN n % 3 = 0 THEN 'Fizz' Else '' END +
    CASE WHEN n % 5 = 0 THEN 'Buzz' Else '' END, ''), RIGHT(n,3))
 FROM t100

To run a similar query in all database, you can use the undocumented sp_msforeachdb. It has been mentioned in another answer, but it is sp_msforeachdb, not sp_foreachdb.

Be careful when using it though, as some things are not what you expect. Consider this example

exec sp_msforeachdb 'select count(*) from sys.objects'

Instead of the counts of objects within each DB, you will get the SAME count reported, begin that of the current DB. To get around this, always "use" the database first. Note the square brackets to qualify multi-word database names.

exec sp_msforeachdb 'use [?]; select count(*) from sys.objects'

For your specific query about populating a tally table, you can use something like the below. Not sure about the DATE column, so this tally table has only the DBNAME and IMG_COUNT columns, but hope it helps you.

create table #tbl (dbname sysname, img_count int);

exec sp_msforeachdb '
use [?];
if object_id(''tbldoc'') is not null
insert #tbl
select ''?'', count(*) from tbldoc'

select * from #tbl

2.Password submitter that uses a HTA pop-up . This is a hybrit .bat/jscript/mshta file and should be saved as a .bat:

<!-- :

@echo off
for /f "tokens=* delims=" %%p in ('mshta.exe "%~f0"') do (
    set "pass=%%p"
)

echo your password is %pass%
exit /b
-->

<html>
<head><title>Password submitter</title></head>
<body>

    <script language='javascript' >
        window.resizeTo(300,150);
        function entperPressed(e){
                if (e.keyCode == 13) {
                    pipePass();
                }
        }
        function pipePass() {
            var pass=document.getElementById('pass').value;
            var fso= new ActiveXObject('Scripting.FileSystemObject').GetStandardStream(1);
            close(fso.Write(pass));

        }
    </script>

    <input type='password' name='pass' size='15' onkeypress="return entperPressed(event)" ></input>

You are almost there. (note change in the return value of FindWindow declaration). I'd recommend using RegisterWindowMessage in this case so you don't have to worry about the ins and outs of WM_USER.

[DllImport("user32.dll")]    
public static extern IntPtr FindWindow(string lpClassName, String lpWindowName);    
[DllImport("user32.dll")]    
public static extern int SendMessage(IntPtr hWnd, int wMsg, IntPtr wParam, IntPtr lParam);    
[DllImport("user32.dll", SetLastError=true, CharSet=CharSet.Auto)]
static extern uint RegisterWindowMessage(string lpString);

public void button1_Click(object sender, EventArgs e)   
{        
     // this would likely go in a constructor because you only need to call it 
     // once per process to get the id - multiple calls in the same instance 
     // of a windows session return the same value for a given string
     uint id = RegisterWindowMessage("MyUniqueMessageIdentifier");
     IntPtr WindowToFind = FindWindow(null, "Form1");    
     Debug.Assert(WindowToFind != IntPtr.Zero);
     SendMessage(WindowToFind, id, IntPtr.Zero, IntPtr.Zero);
}

And then in your Form1 class:

class Form1 : Form
{
    [DllImport("user32.dll", SetLastError=true, CharSet=CharSet.Auto)]
    static extern uint RegisterWindowMessage(string lpString);

    private uint _messageId = RegisterWindowMessage("MyUniqueMessageIdentifier");

    protected override void WndProc(ref Message m)
    {
       if (m.Msg == _messageId)
       {
           // do stuff

       }
       base.WndProc(ref m);
    }
}

Bear in mind I haven't compiled any of the above so some tweaking may be necessary. Also bear in mind that other answers warning you away from SendMessage are spot on. It's not the preferred way of inter module communication nowadays and genrally speaking overriding the WndProc and using SendMessage/PostMessage implies a good understanding of how the Win32 message infrastructure works.

But if you want/need to go this route I think the above will get you going in the right direction.

Based on the above stuff:

import matplotlib.pyplot as plt
import matplotlib.font_manager as fm

fontPath = "/usr/share/fonts/abc.ttf"
font = fm.FontProperties(fname=fontPath, size=10)
font2 = fm.FontProperties(fname=fontPath, size=24)

fig = plt.figure(figsize=(32, 24))
fig.text(0.5, 0.93, "This is my Title", horizontalalignment='center', fontproperties=font2)

plot = fig.add_subplot(1, 1, 1)

plot.xaxis.get_label().set_fontproperties(font)
plot.yaxis.get_label().set_fontproperties(font)
plot.legend(loc='upper right', prop=font)

for label in (plot.get_xticklabels() + plot.get_yticklabels()):
    label.set_fontproperties(font)

is.integer0(integer(0)) #TRUE
is.integer0(0L)         #FALSE
is.integer0(numeric(0)) #FALSE

You can also use assertive for this.

library(assertive)
x <- integer(0)
assert_is_integer(x)
assert_is_empty(x)
x <- 0L
assert_is_integer(x)
assert_is_empty(x)
## Error: is_empty : x has length 1, not 0.
x <- numeric(0)
assert_is_integer(x)
assert_is_empty(x)
## Error: is_integer : x is not of class 'integer'; it has class 'numeric'.

I think is for prevent the browser's HTML parser from interpreting the <script>, and mainly the </script> as the closing tag of the actual script, however I don't think that using document.write is a excellent idea for evaluating script blocks, why don't use the DOM...

var newScript = document.createElement("script");
...

You may use:

• Array.prototype.map()
• Array.prototype.reduce()
• Arrow functions
• Comma operator

To create array of objects:

var source = ['left', 'top'];
const result = source.map(arrValue => ({[arrValue]: 0}));

Demo:

var source = ['left', 'top'];_x000D_
_x000D_
const result = source.map(value => ({[value]: 0}));_x000D_
_x000D_
console.log(result);

Or if you wants to create a single object from values of arrays:

var source = ['left', 'top'];
const result = source.reduce((obj, arrValue) => (obj[arrValue] = 0, obj), {});

Demo:

var source = ['left', 'top'];_x000D_
_x000D_
const result = source.reduce((obj, arrValue) => (obj[arrValue] = 0, obj), {});_x000D_
_x000D_
console.log(result);

A CRC is pretty simple; you take a polynomial represented as bits and the data, and divide the polynomial into the data (or you represent the data as a polynomial and do the same thing). The remainder, which is between 0 and the polynomial is the CRC. Your code is a bit hard to understand, partly because it's incomplete: temp and testcrc are not declared, so it's unclear what's being indexed, and how much data is running through the algorithm.

The way to understand CRCs is to try to compute a few using a short piece of data (16 bits or so) with a short polynomial -- 4 bits, perhaps. If you practice this way, you'll really understand how you might go about coding it.

If you're doing it frequently, a CRC is quite slow to compute in software. Hardware computation is much more efficient, and requires just a few gates.

I got this error when uploading large files (videos). Form worked fine, no mismatch error, but as soon as someone attached a large video file it would throw this token error. Adjusting the maximum allowable file size and increasing the processing time solved this problem for me. Not sure why Laravel throws this error in this case, but here's one more potential solution for you.

Here's a StackOverflow answer that goes into more detail about how to go about solving the large file upload issue.

PHP change the maximum upload file size

just run command line npm install -g npm or sudo npm install -g npmto update it for mac user. That's it.

I recommend to use SMO (Enable TCP/IP Network Protocol for SQL Server). However, it was not available in my case.

I rewrote the WMI commands from Krzysztof Kozielczyk to PowerShell.

# Enable TCP/IP

Get-CimInstance -Namespace root/Microsoft/SqlServer/ComputerManagement10 -ClassName ServerNetworkProtocol -Filter "InstanceName = 'SQLEXPRESS' and ProtocolName = 'Tcp'" |
Invoke-CimMethod -Name SetEnable

# Open the right ports in the firewall
New-NetFirewallRule -DisplayName 'MSSQL$SQLEXPRESS' -Direction Inbound -Action Allow -Protocol TCP -LocalPort 1433

# Modify TCP/IP properties to enable an IP address

$properties = Get-CimInstance -Namespace root/Microsoft/SqlServer/ComputerManagement10 -ClassName ServerNetworkProtocolProperty -Filter "InstanceName='SQLEXPRESS' and ProtocolName = 'Tcp' and IPAddressName='IPAll'"
$properties | ? { $_.PropertyName -eq 'TcpPort' } | Invoke-CimMethod -Name SetStringValue -Arguments @{ StrValue = '1433' }
$properties | ? { $_.PropertyName -eq 'TcpPortDynamic' } | Invoke-CimMethod -Name SetStringValue -Arguments @{ StrValue = '' }

# Restart SQL Server

Restart-Service 'MSSQL$SQLEXPRESS'

Guessing that what you want to do, is call Files.lines(...) on a resource that comes from the classpath - possibly from within a jar.

Since Oracle convoluted the notion of when a Path is a Path by not making getResource return a usable path if it resides in a jar file, what you need to do is something like this:

Stream<String> stream = new BufferedReader(new InputStreamReader(ClassLoader.getSystemResourceAsStream("/filename.txt"))).lines();

I ended up using object spread operator, since it is part of the ECMAScript 2015 (ES6) standard.

const array = ['a', 'b', 'c'];
console.log({...array});
// it outputs {0:'a', 1:'b', 2:'c'}

Made the following fiddle as an example.

Well, for one thing your epression can be simplified:

$("#pDetails").attr("style")

since there should only be one element for any given ID and the ID selector will be much faster than the attribute id selector you're using.

If you just want to return the display value or something, use css():

$("#pDetails").css("display")

If you want to search for elements that have display none, that's a lot harder to do reliably. This is a rough example that won't be 100%:

$("[style*='display: none']")

but if you just want to find things that are hidden, use this:

$(":hidden")

To complement the previous stated solution, use:

str = str.replace("%", "%%");

It is same way as you do for the two divs, just float the third one to left or right too.

<style>
  .left{float:left; width:33%;}
</style>

<div class="left">...</div>
<div class="left">...</div>
<div class="left">...</div>

You would need to enclose the pattern in a delimiter - typically a slash (/) is used. Try this:

echo preg_replace("/[^0-9]/","",'604-619-5135');

Just for anyone who still has an issue, I also had an issue where I typed ngif rather than ngIf (notice the capital 'I').

There are many ways to get a page from the command line... but it also depends if you want the code source or the page itself:

If you need the code source:

with curl:

curl $url

with wget:

wget -O - $url

but if you want to get what you can see with a browser, lynx can be useful:

lynx -dump $url

I think you can find so many solutions for this little problem, maybe you should read all man pages for those commands. And don't forget to replace $url by your URL :)

Good luck :)

The limit is not 2g or 3gb its 4gb for 32bit.

The reason people think its 3gb is that the OS shows 3gb free when they really have 4gb of system ram.

Its total RAM of 4gb. So if you have a 1 gb video card that counts as part of the total ram viewed by the 32bit OS.

4Gig not 3 not 2 got it?

You should never need to modify the path directly, either through environment variables or sys.path. Whether you use the os (ex. apt-get), or pip in a virtualenv, packages will be installed to a location already on the path.

In your example, GNU Radio is installed to the system Python 2's standard site-packages location, which is already in the path. Pointing PyCharm at the correct interpreter is enough; if it isn't there is something else wrong that isn't apparent. It may be that /usr/bin/python does not point to the same interpreter that GNU Radio was installed in; try pointing specifically at the python2.7 binary. Or, PyCharm used to be somewhat bad at detecting packages; File > Invalidate Caches > Invalidate and Restart would tell it to rescan.

This answer will cover how you should set up a project environment, install packages in different scenarios, and configure PyCharm. I refer multiple times to the Python Packaging User Guide, written by the same group that maintains the official Python packaging tools.

The correct way to develop a Python application is with a virtualenv. Packages and version are installed without affecting the system or other projects. PyCharm has a built-in interface to create a virtualenv and install packages. Or you can create it from the command line and then point PyCharm at it.

$ cd MyProject
$ python2 -m virtualenv env
$ . env/bin/activate
$ pip install -U pip setuptools  # get the latest versions
$ pip install flask  # install other packages

In your PyCharm project, go to File > Settings > Project > Project Interpreter. If you used virtualenvwrapper or PyCharm to create the env, then it should show up in the menu. If not, click the gear, choose Add Local, and locate the Python binary in the env. PyCharm will display all the packages in the selected env.

In some cases, such as with GNU Radio, there is no package to install with pip, the package was installed system-wide when you install the rest of GNU Radio (ex. apt-get install gnuradio). In this case, you should still use a virtualenv, but you'll need to make it aware of this system package.

$ python2 -m virtualenv --system-site-packages env

Unfortunately it looks a little messy, because all system packages will now appear in your env, but they are just links, you can still safely install or upgrade packages without affecting the system.

In some cases, you will have multiple local packages you're developing, and will want one project to use the other package. In this case you might think you have to add the local package to the other project's path, but this is not the case. You should install your package in development mode. All this requires is adding a setup.py file to your package, which will be required anyway to properly distribute and deploy the package later.

Minimal setup.py for your first project:

from setuptools import setup, find_packages

setup(
    name='mypackage',
    version='0.1',
    packages=find_packages(),
)

Then install it in your second project's env:

$ pip install -e /path/to/first/project

if (capital.touched && capital != undefined && capital.length < 1 ) { 
//capital does exists
}

Without using regex (though I would only do this if the search string is user input):

var str = 'Hello/ world/ this has two slashes!';
alert(str.split('/').join(',')); // alerts 'Hello, world, this has two slashes!' 

You could try:

print ''.join(ch for ch in some_string if ch.isalnum())

The simplest lines of code that works for me are are follows:

AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setView(R.layout.layout_resource_id);
builder.show();

Whatever the type of layout(LinearLayout, FrameLayout, RelativeLayout) will work by setView and will just differ in the appearance and behavior.

A table contains data, a view is just a SELECT statement which has been saved in the database (more or less, depending on your database).

The advantage of a view is that it can join data from several tables thus creating a new view of it. Say you have a database with salaries and you need to do some complex statistical queries on it.

Instead of sending the complex query to the database all the time, you can save the query as a view and then SELECT * FROM view

You can use Column.isNull / Column.isNotNull:

df.where(col("dt_mvmt").isNull())

df.where(col("dt_mvmt").isNotNull())

If you want to simply drop NULL values you can use na.drop with subset argument:

df.na.drop(subset=["dt_mvmt"])

Equality based comparisons with NULL won't work because in SQL NULL is undefined so any attempt to compare it with another value returns NULL:

sqlContext.sql("SELECT NULL = NULL").show()
## +-------------+
## |(NULL = NULL)|
## +-------------+
## |         null|
## +-------------+


sqlContext.sql("SELECT NULL != NULL").show()
## +-------------------+
## |(NOT (NULL = NULL))|
## +-------------------+
## |               null|
## +-------------------+

The only valid method to compare value with NULL is IS / IS NOT which are equivalent to the isNull / isNotNull method calls.

First create a real, permanent table as a template that has the required layout for the returned temporary table, using a naming convention that identifies it as a template and links it symbolically to the SP, eg tmp_SPName_Output. This table will never contain any data.

In the SP, use INSERT to load data into a temp table following the same naming convention, e.g. #SPName_Output which is assumed to exist. You can test for its existence and return an error if it does not.

Before calling the sp use this simple select to create the temp table:

SELECT TOP(0) * INTO #SPName_Output FROM tmp_SPName_Output;
EXEC SPName;
-- Now process records in #SPName_Output;

This has these distinct advantages:

• The temp table is local to the current session, unlike ##, so will not clash with concurrent calls to the SP from different sessions. It is also dropped automatically when out of scope.
• The template table is maintained alongside the SP, so if changes are made to the output (new columns added, for example) then pre-existing callers of the SP do not break. The caller does not need to be changed.
• You can define any number of output tables with different naming for one SP and fill them all. You can also define alternative outputs with different naming and have the SP check the existence of the temp tables to see which need to be filled.
• Similarly, if major changes are made but you want to keep backwards compatibility, you can have a new template table and naming for the later version but still support the earlier version by checking which temp table the caller has created.

You can use the library SectionedRecyclerViewAdapter to group your items in sections and add a header to each section, like on the image below:

First you create your section class:

class MySection extends StatelessSection {

    String title;
    List<String> list;

    public MySection(String title, List<String> list) {
        // call constructor with layout resources for this Section header, footer and items 
        super(R.layout.section_header, R.layout.section_item);

        this.title = title;
        this.list = list;
    }

    @Override
    public int getContentItemsTotal() {
        return list.size(); // number of items of this section
    }

    @Override
    public RecyclerView.ViewHolder getItemViewHolder(View view) {
        // return a custom instance of ViewHolder for the items of this section
        return new MyItemViewHolder(view);
    }

    @Override
    public void onBindItemViewHolder(RecyclerView.ViewHolder holder, int position) {
        MyItemViewHolder itemHolder = (MyItemViewHolder) holder;

        // bind your view here
        itemHolder.tvItem.setText(list.get(position));
    }

    @Override
    public RecyclerView.ViewHolder getHeaderViewHolder(View view) {
        return new SimpleHeaderViewHolder(view);
    }

    @Override
    public void onBindHeaderViewHolder(RecyclerView.ViewHolder holder) {
        MyHeaderViewHolder headerHolder = (MyHeaderViewHolder) holder;

        // bind your header view here
        headerHolder.tvItem.setText(title);
    }
}

Then you set up the RecyclerView with your sections and change the SpanSize of the headers with a GridLayoutManager:

// Create an instance of SectionedRecyclerViewAdapter 
SectionedRecyclerViewAdapter sectionAdapter = new SectionedRecyclerViewAdapter();

// Create your sections with the list of data
MySection section1 = new MySection("My Section 1 title", dataList1);
MySection section2 = new MySection("My Section 2 title", dataList2);

// Add your Sections to the adapter
sectionAdapter.addSection(section1);
sectionAdapter.addSection(section2);

// Set up a GridLayoutManager to change the SpanSize of the header
GridLayoutManager glm = new GridLayoutManager(getContext(), 2);
glm.setSpanSizeLookup(new GridLayoutManager.SpanSizeLookup() {
    @Override
    public int getSpanSize(int position) {
        switch(sectionAdapter.getSectionItemViewType(position)) {
            case SectionedRecyclerViewAdapter.VIEW_TYPE_HEADER:
                return 2;
            default:
                return 1;
        }
    }
});

// Set up your RecyclerView with the SectionedRecyclerViewAdapter
RecyclerView recyclerView = (RecyclerView) findViewById(R.id.recyclerview);
recyclerView.setLayoutManager(glm);
recyclerView.setAdapter(sectionAdapter);

You could find disk intensive full table scans with something like this:

SELECT Disk_Reads DiskReads, Executions, SQL_ID, SQL_Text SQLText, 
   SQL_FullText SQLFullText 
FROM
(
   SELECT Disk_Reads, Executions, SQL_ID, LTRIM(SQL_Text) SQL_Text, 
      SQL_FullText, Operation, Options, 
      Row_Number() OVER 
         (Partition By sql_text ORDER BY Disk_Reads * Executions DESC) 
         KeepHighSQL
   FROM
   (
       SELECT Avg(Disk_Reads) OVER (Partition By sql_text) Disk_Reads, 
          Max(Executions) OVER (Partition By sql_text) Executions, 
          t.SQL_ID, sql_text, sql_fulltext, p.operation,p.options
       FROM v$sql t, v$sql_plan p
       WHERE t.hash_value=p.hash_value AND p.operation='TABLE ACCESS' 
       AND p.options='FULL' AND p.object_owner NOT IN ('SYS','SYSTEM')
       AND t.Executions > 1
   ) 
   ORDER BY DISK_READS * EXECUTIONS DESC
)
WHERE KeepHighSQL = 1
AND rownum <=5;

Nothing printed. The argument must be a pointer to a signed int, where the number of characters written so far is stored.

#include <stdio.h>

int main()
{
  int val;

  printf("blah %n blah\n", &val);

  printf("val = %d\n", val);

  return 0;

}

The previous code prints:

blah  blah
val = 5

Try using

intent.addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP);

and not

intent.setFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP);

> df <- data.frame(matrix(ncol = 300, nrow = 100))
> dim(df)
[1] 100 300

perhaps, you can first determine if the DOM does really exists,

function walkmydog() {
    //when the user starts entering
    var dom = document.getElementById('WallSearch');
    if(dom == null){
        alert('sorry, WallSearch DOM cannot be found');
        return false;    
    }

    if(dom.value.length == 0){
        alert("nothing");
    }
}

if (document.addEventListener){
    document.addEventListener("DOMContentLoaded", walkmydog, false);
}

public boolean isAlertPresent() {

try 
{ 
    driver.switchTo().alert(); 
    system.out.println(" Alert Present");
}  
catch (NoAlertPresentException e) 
{ 
    system.out.println("No Alert Present");
}    

}

you must use import android.support.v7.app.ActionBarDrawerToggle;

and use the constructor

public CustomActionBarDrawerToggle(Activity mActivity,DrawerLayout mDrawerLayout)
{
    super(mActivity, mDrawerLayout, R.string.ns_menu_open, R.string.ns_menu_close);
}

and if the drawer toggle button becomes dark then you must use the supportActionBar provided in the support library.

You can implement supportActionbar from this link: http://developer.android.com/training/basics/actionbar/setting-up.html

It happened to me too. I had tensorflow and it was working pretty well, but when I install tensorflow-gpu along side the previous tensorflow this error arose then I did these 3 steps and it started working with no problem:

1. I removed tensorflow-gpu, tensorflow, tensorflow-base packages from Anaconda. Using.

conda remove tensorflow-gpu tensorflow tensorflow-base

2. re-installed tensorflow. Using

conda install tensorflow

Found the problem, need to use function(err,obj) instead:

Auth.findOne({nick: 'noname'}, function(err,obj) { console.log(obj); });

I think you are asking two things which are not necessarily the same

I want to extract every 6th element of the original

You can do this by indexing a sequence:

foo <- 1:120
foo[1:20*6]

I would like to create a vector in which each element is the i+6th element of another vector.

An easy way to do this is to supplement a logical factor with FALSEs until i+6:

foo <- 1:120
i <- 1
foo[1:(i+6)==(i+6)]
[1]   7  14  21  28  35  42  49  56  63  70  77  84  91  98 105 112 119

i <- 10
foo[1:(i+6)==(i+6)]
[1]  16  32  48  64  80  96 112

An quit option in the Console Panel will also clear all variables in variable explorer

*** Note that you will be loosing all the code which you have run in Console Panel

Is something wrong with the packages, when it generating de file /usr/bin/pip, you have to change the import:

from pip import main

to

from pip._internal import main

That solves the problem, I'm not sure why it generated, but it saids somthing in the following issue:

After pip 10 upgrade on pyenv "ImportError: cannot import name 'main'"

A backreference to the whole match value is \g<0>, see re.sub documentation:

The backreference \g<0> substitutes in the entire substring matched by the RE.

See the Python demo:

import re
method = 'images/:id/huge'
print(re.sub(r':[a-z]+', r'<span>\g<0></span>', method))
# => images/<span>:id</span>/huge

SELECT 
    distributor_id, 
    COUNT(*) AS TOTAL, 
    COUNT(IF(level='exec',1,null)),
    COUNT(IF(level='personal',1,null))
FROM sometable;

COUNT only counts non null values and the DECODE will return non null value 1 only if your condition is satisfied.

Sometimes Xcode missed customModule="AppName" customModuleProvider="target"

To fix it, open storyboard as source code and replace this line:

<viewController storyboardIdentifier="StoryboardId" id="SomeID" customClass="CustomClass"
sceneMemberID="viewController">

to this:

<viewController storyboardIdentifier="StoryboardId" id="SomeID" customClass="CustomClass"
 customModule="AppName" customModuleProvider="target" sceneMemberID="viewController">

Surprised that no one mentioned how a logger is created/retrieved. For example, below shows how Log4J logger is retrieved.

// Retrieve a logger named according to the value of the name parameter. If the named logger already exists, then the existing instance will be returned. Otherwise, a new instance is created.
public static Logger getLogger(String name)

There are some levels of indirections, but the key part is below method which pretty much tells everything about how it works. It uses a hash table to store the exiting loggers and the key is derived from name. If the logger doesn't exist for a give name, it uses a factory to create the logger and then adds it to the hash table.

69   Hashtable ht;
...
258  public
259  Logger getLogger(String name, LoggerFactory factory) {
260    //System.out.println("getInstance("+name+") called.");
261    CategoryKey key = new CategoryKey(name);
262    // Synchronize to prevent write conflicts. Read conflicts (in
263    // getChainedLevel method) are possible only if variable
264    // assignments are non-atomic.
265    Logger logger;
266
267    synchronized(ht) {
268      Object o = ht.get(key);
269      if(o == null) {
270        logger = factory.makeNewLoggerInstance(name);
271        logger.setHierarchy(this);
272        ht.put(key, logger);
273        updateParents(logger);
274        return logger;
275      } else if(o instanceof Logger) {
276        return (Logger) o;
277      } 
...

TL;DR:

socket.send(data, callback) is essentially equivalent to calling socket.emit('message', JSON.stringify(data), callback)

Without looking at the source code, I would assume that the send function is more efficient edit: for sending string messages, at least?

So yeah basically emit allows you to send objects, which is very handy.

Take this example with socket.emit:

sendMessage: function(type, message) {
    socket.emit('message', {
        type: type,
        message: message
    });
}

and for those keeping score at home, here is what it looks like using socket.send:

sendMessage: function(type, message) {
    socket.send(JSON.stringify({
        type: type,
        message: message
    }));
}

Elements are added to list using append():

>>> data = {'list': [{'a':'1'}]}
>>> data['list'].append({'b':'2'})
>>> data
{'list': [{'a': '1'}, {'b': '2'}]}

If you want to add element to a specific place in a list (i.e. to the beginning), use insert() instead:

>>> data['list'].insert(0, {'b':'2'})
>>> data
{'list': [{'b': '2'}, {'a': '1'}]}

After doing that, you can assemble JSON again from dictionary you modified:

>>> json.dumps(data)
'{"list": [{"b": "2"}, {"a": "1"}]}'

The resolution to this problem for me, was to notify the sender that he did use the Public key that I sent them but rather someone elses. You should see the key that they used. Tell them to use the correct one.

I have a slight preference for BETWEEN because it makes it instantly clear to the reader that you are checking one field for a range. This is especially true if you have similar field names in your table.

If, say, our table has both a transactiondate and a transitiondate, if I read

transactiondate between ...

I know immediately that both ends of the test are against this one field.

If I read

transactiondate>='2009-04-17' and transactiondate<='2009-04-22'

I have to take an extra moment to make sure the two fields are the same.

Also, as a query gets edited over time, a sloppy programmer might separate the two fields. I've seen plenty of queries that say something like

where transactiondate>='2009-04-17'
  and salestype='A'
  and customernumber=customer.idnumber
  and transactiondate<='2009-04-22'

If they try this with a BETWEEN, of course, it will be a syntax error and promptly fixed.

Here is some code that will give you the general idea.

You need to create a custom ClientHttpRequestFactory in order to trust the certificate. It looks like this:

final ClientHttpRequestFactory clientHttpRequestFactory =
        new MyCustomClientHttpRequestFactory(org.apache.http.conn.ssl.SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER, serverInfo);
    restTemplate.setRequestFactory(clientHttpRequestFactory);

This is the implementation for MyCustomClientHttpRequestFactory:

public class MyCustomClientHttpRequestFactory  extends SimpleClientHttpRequestFactory {

private final HostnameVerifier hostNameVerifier;
private final ServerInfo serverInfo;

public MyCustomClientHttpRequestFactory (final HostnameVerifier hostNameVerifier,
    final ServerInfo serverInfo) {
    this.hostNameVerifier = hostNameVerifier;
    this.serverInfo = serverInfo;
}

@Override
protected void prepareConnection(final HttpURLConnection connection, final String httpMethod)
    throws IOException {
    if (connection instanceof HttpsURLConnection) {
        ((HttpsURLConnection) connection).setHostnameVerifier(hostNameVerifier);
        ((HttpsURLConnection) connection).setSSLSocketFactory(initSSLContext()
            .getSocketFactory());
    }
    super.prepareConnection(connection, httpMethod);
}

private SSLContext initSSLContext() {
    try {
        System.setProperty("https.protocols", "TLSv1");

        // Set ssl trust manager. Verify against our server thumbprint
        final SSLContext ctx = SSLContext.getInstance("TLSv1");
        final SslThumbprintVerifier verifier = new SslThumbprintVerifier(serverInfo);
        final ThumbprintTrustManager thumbPrintTrustManager =
            new ThumbprintTrustManager(null, verifier);
        ctx.init(null, new TrustManager[] { thumbPrintTrustManager }, null);
        return ctx;
    } catch (final Exception ex) {
        LOGGER.error(
            "An exception was thrown while trying to initialize HTTP security manager.", ex);
        return null;
    }
}

In this case my serverInfo object contains the thumbprint of the server. You need to implement the TrustManager interface to get the SslThumbprintVerifier or any other method you want to verify your certificate (you can also decide to also always return true).

The value org.apache.http.conn.ssl.SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER allows all host names. If you need to verify the host name, you will need to implement it differently.

I'm not sure about the user and password and how you implemented it. Often, you need to add a header to the restTemplate named Authorization with a value that looks like this: Base: <encoded user+password>. The user+password must be Base64 encoded.

Chris' solution worked for me as well. I did however get a follow error message that states:

Could not load file or assembly 'Oracle.DataAccess' or one of its dependencies. An attempt was made to load a program with an incorrect format.

Apparently, in the foreign language of Oraclish, that means that your program are either targeting all platforms, or 32-bit machines. Simply change your target platform in Project Properties to 64-bit and hope for the best.

When you set up your validation, you should be saving the validator object. you can use this to validate individual fields.

<script type="text/javascript">
var _validator;
$(function () {    
     _validator = $("#form").validate();   
});

function doSomething() {    
     _validator.element($('#someElement'));
}
</script>

\n is add a new line.

Please note java has method System.out.println("Write text here");

Notice the difference:

Code:

System.out.println("Text 1");
System.out.println("Text 2");

Output:

Text 1
Text 2

Code:

System.out.print("Text 1");
System.out.print("Text 2");

Output:

Text 1Text 2

See ?merge:

the name "row.names" or the number 0 specifies the row names.

Example:

Google "select item selenium webdriver" brings up How do I set an option as selected using Selenium WebDriver (selenium 2.0) client in ruby as first result. This is not Java, but you should be able to translate it without too much work. https://sqa.stackexchange.com/questions/1355/what-is-the-correct-way-to-select-an-option-using-seleniums-python-webdriver is in the top 5, again not Java but the API is very similar.

its very similar with nodejs

var User= require('./Users');

in this case its React:

import User from './User'

right now you can use

return (
      <Users></Users>
    )

When you run your form and you want showing text in textbox is clear so you put the code : -

textBox1.text = String.Empty;

Where textBox1 is your textbox name.

Here is a version that uses sys.excepthook

import traceback
import sys

logger = logging.getLogger()

def handle_excepthook(type, message, stack):
     logger.error(f'An unhandled exception occured: {message}. Traceback: {traceback.format_tb(stack)}')

sys.excepthook = handle_excepthook

function get_random_color() {
    return "#" + (Math.round(Math.random() * 0XFFFFFF)).toString(16);
}

Remove the course_enrollment_settings.base_price immediately after CASE:

SELECT
   CASE
    WHEN course_enrollment_settings.base_price = 0      THEN 1
    ...
    END

CASE has two different forms, as detailed in the manual. Here, you want the second form since you're using search conditions.

You can get every file, then filter the array:

public static IEnumerable<FileInfo> GetFilesByExtensions(this DirectoryInfo dirInfo, params string[] extensions)
{
    var allowedExtensions = new HashSet<string>(extensions, StringComparer.OrdinalIgnoreCase);

    return dirInfo.EnumerateFiles()
                  .Where(f => allowedExtensions.Contains(f.Extension));
}

This will be (marginally) faster than every other answer here.
In .Net 3.5, replace EnumerateFiles with GetFiles (which is slower).

And use it like this:

var files = new DirectoryInfo(...).GetFilesByExtensions(".jpg", ".mov", ".gif", ".mp4");

It may have been an oversight of other answers, or perhaps it is a requirement of the user to indeed need console output, but the obvious answer to me is to create a secondary window that can be shown or hidden (with a checkbox or button) that shows all messages by appending lines of text to a text box widget and use that as a console?

The benefits of such a solution are:

• A simple solution (providing all it displays is a simple log).
• The ability to dock the 'console' widget onto the main application window. (In Qt, anyhow).
• The ability to create many consoles (if more than 1 thread, etc).
• A pretty easy change from local console output to sending log over network to a client.

Hope this gives you food for thought, although I am not in any way yet qualified to postulate on how you should do this, I can imagine it is something very achievable by any one of us with a little searching / reading!

static class Extensions
{
    public static T[] Concat<T>(this T[] array1, params T[] array2) => ConcatArray(array1, array2);

    public static T[] ConcatArray<T>(params T[][] arrays)
    {
        int l, i;

        for (l = i = 0; i < arrays.Length; l += arrays[i].Length, i++);

        var a = new T[l];

        for (l = i = 0; i < arrays.Length; l += arrays[i].Length, i++)
            arrays[i].CopyTo(a, l);

        return a;
    }
}

I think the above solution is more general & lighter than the others I saw here. It is more general because it doesn't limit concatenation for only two arrays and is lighter because it doesn't use LINQ nor List.

Note the solution is concise and the added generality doesn't add significant runtime overhead.

Actually, I was also having the same problem. I was running Ubuntu. Mine problem arises because I'd lost my public key of the Ubuntu. Even updating my system was not happening. It was giving GPG error. In that case, you can regain your key by using this command:

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys <key in GPG error>

After that npm works fine!

//Javascript file 1

localStorage.setItem('Data',10);

Don't reinvent the wheel

IntentService extends Service class which clearly means that IntentService is intentionally made for same purpose.

So what is the purpose ?

`IntentService's purpose is to make our job easier to run background tasks without even worrying about

• Creation of worker thread

• Queuing the processing multiple-request one by one (Threading)

• Destroying the Service

So NO, Service can do any task which an IntentService would do. If your requirements fall under the above-mentioned criteria, then you don't have to write those logics in the Service class. So don't reinvent the wheel because IntentService is the invented wheel.

The "Main" difference

The Service runs on the UI thread while an IntentService runs on a separate thread

When do you use IntentService?

When you want to perform multiple background tasks one by one which exists beyond the scope of an Activity then the IntentService is perfect.

How IntentService is made from Service

A normal service runs on the UI Thread(Any Android Component type runs on UI thread by default eg Activity, BroadcastReceiver, ContentProvider and Service). If you have to do some work that may take a while to complete then you have to create a thread. In the case of multiple requests, you will have to deal with synchronization. IntentService is given some default implementation which does those tasks for you.
According to developer page

1. IntentService creates a Worker Thread

2. IntentService creates a Work Queue which sends request to onHandleIntent() method one by one

3. When there is no work then IntentService calls stopSelf() method
4. Provides default implementation for onBind() method which is null
5. Default implementation for onStartCommand() which sends Intent request to WorkQueue and eventually to onHandleIntent()

You should use the UPnP protocol to query your router for this information. Most importantly, this does not rely on an external service, which all the other answers to this question seem to suggest.

There's a Python library called miniupnp which can do this, see e.g. miniupnpc/testupnpigd.py.

pip install miniupnpc

Based on their example you should be able to do something like this:

import miniupnpc

u = miniupnpc.UPnP()
u.discoverdelay = 200
u.discover()
u.selectigd()
print('external ip address: {}'.format(u.externalipaddress()))

This works for me, I only need first numbers in string:

TO_NUMBER(regexp_substr(h.HIST_OBSE, '\.*[[:digit:]]+\.*[[:digit:]]*'))

the field had the following string: "(43 Paginas) REGLAS DE PARTICIPACION".

result field: 43

After building your project the website needs some time to walk through the new dll :). It's normal that loading a webpage after rebuilding takes some time. This shouldn't happen when only changing something in for example javascript.

CSL's answer was implemented in a project I'm working on but the problem I incurred was scaling out on Azure broke our file downloads. Instead, I was able to do this with one AJAX call:

SERVER

[HttpPost]
public FileResult DownloadInvoice(int id1, int id2)
{
    //necessary to get the filename in the success of the ajax callback
    HttpContext.Response.Headers.Add("Access-Control-Expose-Headers", "Content-Disposition");

    byte[] fileBytes = _service.GetInvoice(id1, id2);
    string fileName = "Invoice.xlsx";
    return File(fileBytes, System.Net.Mime.MediaTypeNames.Application.Octet, fileName);
}

CLIENT (modified version of Handle file download from ajax post)

$("#downloadInvoice").on("click", function() {
    $("#loaderInvoice").removeClass("d-none");

    var xhr = new XMLHttpRequest();
    var params = [];
    xhr.open('POST', "@Html.Raw(Url.Action("DownloadInvoice", "Controller", new { id1 = Model.Id1, id2 = Model.Id2 }))", true);
    xhr.responseType = 'arraybuffer';
    xhr.onload = function () {
        if (this.status === 200) {
            var filename = "";
            var disposition = xhr.getResponseHeader('Content-Disposition');
            if (disposition && disposition.indexOf('attachment') !== -1) {
                var filenameRegex = /filename[^;=\n]*=((['"]).*?\2|[^;\n]*)/;
                var matches = filenameRegex.exec(disposition);
                if (matches != null && matches[1]) filename = matches[1].replace(/['"]/g, '');
            }
            var type = xhr.getResponseHeader('Content-Type');

            var blob = typeof File === 'function'
                ? new File([this.response], filename, { type: type })

                    var a = document.createElement("a");
                    // safari doesn't support this yet
                    if (typeof a.download === 'undefined') {
                        window.location = downloadUrl;
                    } else {

    xhr.send($.param(params));
});

Other answers don't work in angular 5?

I got an error because DatePipe is not a provider, so it cannot be injected. One solution is to put it as a provider in your app module but my preferred solution was to instantiate it.

Instantiate it where needed:

I looked at DatePipe's source code to see how it got the locale: https://github.com/angular/angular/blob/5.2.5/packages/common/src/pipes/date_pipe.ts#L15-L174

I wanted to use it within a pipe, so my example is within another pipe:

    import { Pipe, PipeTransform, Inject, LOCALE_ID } from '@angular/core';
    import { DatePipe } from '@angular/common';

    @Pipe({
        name: 'when',
    })
    export class WhenPipe implements PipeTransform {
        static today = new Date((new Date).toDateString().split(' ').slice(1).join(' '));
        datePipe: DatePipe;

        constructor(@Inject(LOCALE_ID) private locale: string) {
            this.datePipe = new DatePipe(locale);
        }
        transform(value: string | Date): string {
            if (typeof(value) === 'string')
                value = new Date(value);

            return this.datePipe.transform(value, value < WhenPipe.today ? 'MMM d': 'shortTime')
        }
    }

The key here is importing Inject, and LOCALE_ID from angular's core, and then injecting that so you can give it to the DatePipe to instantiate it properly.

Make DatePipe a provider

In your app module you could also add DatePipe to your providers array like this:

    import { DatePipe } from '@angular/common';

    @NgModule({
        providers: [
            DatePipe
        ]
    })

Now you can just have it injected in your constructor where needed (like in cexbrayat's answer).

Summary:

Either solution worked, I don't know which one angular would consider most "correct" but I chose to instantiate it manually since angular didn't provide datepipe as a provider itself.

As RocketDonkey suggested, your module itself needs to have some docstrings.

For example, in myModule/__init__.py:

"""
The mod module
"""

You'd also want to generate documentation for each file in myModule/*.py using

pydoc myModule.thefilename

to make sure the generated files match the ones that are referenced from the main module documentation file.

You have to use Javascript submit function on your form object. Take a look in other functions.

<form action="showMessage.jsp" method="post">
    <a href="javascript:;" onclick="parentNode.submit();"><%=n%></a>
    <input type="hidden" name="mess" value=<%=n%>/>
</form>

Update from 10 years later In 2008 the hard drives you would run a database on would have much different characteristics and much higher cost than the disks you would store files on. These days there are much better solutions for storing files that didn't exist 10 years ago and I would revoke this advice and advise readers to look at some of the other answers in this thread.

Original

Don't store in images in the database unless you absolutely have to. I understand that this is not a web application, but if there isn't a shared file location that you can point to save the location of the file in the database.

//linuxserver/images/imagexxx.jpg

then perhaps you can quickly set up a webserver and store the web urls in the database (as well as the local path). While databases can handle LOB's and 3000 images (4-6 Megapixels, assuming 500K an image) 1.5 Gigs isn't a lot of space file systems are much better designed for storing large files than a database is.

2017 Update - since WooCommerce 3:

global $product;
$id = $product->get_id();

Woocommerce doesn't like you accessing those variables directly. This will get rid of any warnings from woocommerce if your wp_debug is true.

in your location block you can do:

location / {
  try_files $uri $uri/index.html;
}

which will tell ngingx to look for a file with the exact name given first, and if none such file is found it will try uri/index.html. So if a request for https://www.example.com/ comes it it would look for an exact file match first, and not finding that would then check for index.html

On ubuntu you can add this PPA Repository and use it to install python 3.7: https://launchpad.net/~jonathonf/+archive/ubuntu/python-3.7

Or a different PPA that provides several Python versions is Deadsnakes: https://launchpad.net/~deadsnakes/+archive/ubuntu/ppa

See also here: https://askubuntu.com/questions/865554/how-do-i-install-python-3-6-using-apt-get (I know it says 3.6 in the url, but the deadsnakes ppa also contains 3.7 so you can use it for 3.7 just the same)

If you want "official" you'd have to install it from the sources from the site, get the code (which you already downloaded) and do this:

tar -xf Python-3.7.0.tar.xz
cd Python-3.7.0
./configure
make
sudo make install        <-- sudo is required.

This might take a while

You can use a while loop to delete item/items matching ChunkID. Here is my suggestion:

public void DeleteChunk(int ChunkID)
{
   int i = 0;
   while (i < ChunkList.Count) 
   {
      Chunk currentChunk = ChunkList[i];
      if (currentChunk.UniqueID == ChunkID) {
         ChunkList.RemoveAt(i);
      }
      else {
        i++;
      }
   }
}

A good way to test if a string is a correct date is to use the command date:

if date -d "${DATE}" >/dev/null 2>&1
then
  # do what you need to do with your date
else
  echo "${DATE} incorrect date" >&2
  exit 1
fi

from comment: one can use formatting

if [ "2017-01-14" == $(date -d "2017-01-14" '+%Y-%m-%d') ] 

Just to add something to @Habib's answer, you can also check if given JSON is from a valid type:

public static bool IsValidJson<T>(this string strInput)
{
    if(string.IsNullOrWhiteSpace(strInput)) return false;

    strInput = strInput.Trim();
    if ((strInput.StartsWith("{") && strInput.EndsWith("}")) || //For object
        (strInput.StartsWith("[") && strInput.EndsWith("]"))) //For array
    {
        try
        {
            var obj = JsonConvert.DeserializeObject<T>(strInput);
            return true;
        }
        catch // not valid
        {             
            return false;
        }
    }
    else
    {
        return false;
    }
}

The easiest solution is to crate a table with 3 columns and center that table.

html:

 <div id="cont">
        <table class="aa">
            <tr>
                <td>
                    <div id="left">
                        <h3 class="hh">Content1</h3>
                        </div>
                    </td>
                <td>
                    <div id="center">
                        <h3 class="hh">Content2</h3>
                        </div>
                 </td>
                <td>
                    <div id="right"><h3 class="hh">Content3</h3>
                        </div>
                </td>
            </tr>
        </table>
    </div>

css:

#cont 
{
  margin: 0px auto;    
  padding: 10px 10px;
}

#left
{    
  width: 200px;
  height: 160px;
  border: 5px solid #fff;
}

#center
{
  width: 200px;
  height: 160px;
  border: 5px solid #fff;
}

#right
{
  width: 200px;
  height: 160px;
  border: 5px solid #fff;
}

HTML:

<html>
  <head>

  </head>
  <body>

    <div id='status'>jQuery is not loaded yet.</div>
    <input type='button' value='Click here to load it.' onclick='load()' />

  </body>
</html>   

Script:

   <script>

        load = function() {
          load.getScript("jquery-1.7.2.js");
          load.tryReady(0); // We will write this function later. It's responsible for waiting until jQuery loads before using it.
        }

        // dynamically load any javascript file.
        load.getScript = function(filename) {
          var script = document.createElement('script')
          script.setAttribute("type","text/javascript")
          script.setAttribute("src", filename)
          if (typeof script!="undefined")
          document.getElementsByTagName("head")[0].appendChild(script)
        }

        </script>

I was searching to get a result for this either and I ended up with;

const MyObject = {
    SubObject: {
        'eu': [0, "asd", true, undefined],
        'us': [0, "asd", false, null],
        'aus': [0, "asd", false, 0]
    }
};

For those who wanted the result as a string:

Object.keys(MyObject.SubObject).toString()

output: "eu,us,aus"

For those who wanted the result as an array:

Array.from(Object.keys(MyObject))

output: Array ["eu", "us", "aus"]

For those who are looking for a "contains" type method: as numeric result:

console.log(Object.keys(MyObject.SubObject).indexOf("k"));

output: -1

console.log(Object.keys(MyObject.SubObject).indexOf("eu"));

output: 0

console.log(Object.keys(MyObject.SubObject).indexOf("us"));

output: 3

as boolean result:

console.log(Object.keys(MyObject.SubObject).includes("eu"));

output: true

In your case;

var myVar = { typeA: { option1: "one", option2: "two" } }_x000D_
_x000D_
    // Example 1_x000D_
    console.log(Object.keys(myVar.typeA).toString()); // Result: "option1, option2"_x000D_
_x000D_
    // Example 2_x000D_
    console.log(Array.from(Object.keys(myVar.typeA))); // Result: Array ["option1", "option2" ]_x000D_
    _x000D_
    // Example 3 as numeric_x000D_
    console.log((Object.keys(myVar.typeA).indexOf("option1")>=0)?'Exist!':'Does not exist!'); // Result: Exist!_x000D_
    _x000D_
    // Example 3 as boolean_x000D_

Java 8 introduced default implementation of forEach() inside the Iterable interface , you can easily do it by declarative approach .

  List<String> values = Arrays.asList("Yasir","Shabbir","Choudhary");

  values.forEach( value -> System.out.println(value));

Here is the code of Iterable interface

  default void forEach(Consumer<? super T> action) {
    Objects.requireNonNull(action);
    for (T t : this) {
        action.accept(t);
    }
}

Reference

About your command line:

root@debian:/# sudo iptables -A INPUT -p tcp --dport 3306 --jump ACCEPT
root@debian:/# iptables-save

• You are already authenticated as root so sudo is redundant there.

• You are missing the -j or --jump just before the ACCEPT parameter (just tought that was a typo and you are inserting it correctly).

About yout question:

If you are inserting the iptables rule correctly as you pointed it in the question, maybe the issue is related to the hypervisor (virtual machine provider) you are using.

If you provide the hypervisor name (VirtualBox, VMWare?) I can further guide you on this but here are some suggestions you can try first:

check your vmachine network settings and:

• if it is set to NAT, then you won't be able to connect from your base machine to the vmachine.

• if it is set to Hosted, you have to configure first its network settings, it is usually to provide them an IP in the range 192.168.56.0/24, since is the default the hypervisors use for this.

• if it is set to Bridge, same as Hosted but you can configure it whenever IP range makes sense for you configuration.

Hope this helps.

From Get-ScriptDirectory to the Rescue blog entry ...

function Get-ScriptDirectory
{
  $Invocation = (Get-Variable MyInvocation -Scope 1).Value
  Split-Path $Invocation.MyCommand.Path
}

ok so what if it say this: between the gt/lt signs

Import Project="$(MSBuildExtensionsPath)\Microsoft\Silverlight\v3.0\Microsoft.Silverlight.CSharp.targets" /

how do i fix the targets error?

I also found that import string in a demo project (specifically "Build your own MVVM Framework" by Rob Eisenburg).

If you replace that import with the one suggested by lomaxx VS2010 RTM reports that you need to install this.

You can also do like this :

  $("#table-filters li").parent().find('li').removeClass("active");

Yes, there does seem to be 3rd libraries (none in Java Math). Two that have come up are:

http://opsresearch.com/app/

http://www.iro.umontreal.ca/~simardr/ssj/indexe.html

but, it is actually not that difficult to write your own methods to calculate mean, median, mode and range.

MEAN

public static double mean(double[] m) {
    double sum = 0;
    for (int i = 0; i < m.length; i++) {
        sum += m[i];
    }
    return sum / m.length;
}

MEDIAN

// the array double[] m MUST BE SORTED
public static double median(double[] m) {
    int middle = m.length/2;
    if (m.length%2 == 1) {
        return m[middle];
    } else {
        return (m[middle-1] + m[middle]) / 2.0;
    }
}

MODE

public static int mode(int a[]) {
    int maxValue, maxCount;

    for (int i = 0; i < a.length; ++i) {
        int count = 0;
        for (int j = 0; j < a.length; ++j) {
            if (a[j] == a[i]) ++count;
        }
        if (count > maxCount) {
            maxCount = count;
            maxValue = a[i];
        }
    }

    return maxValue;
}

UPDATE

As has been pointed out by Neelesh Salpe, the above does not cater for multi-modal collections. We can fix this quite easily:

public static List<Integer> mode(final int[] numbers) {
    final List<Integer> modes = new ArrayList<Integer>();
    final Map<Integer, Integer> countMap = new HashMap<Integer, Integer>();

    int max = -1;

    for (final int n : numbers) {
        int count = 0;

        if (countMap.containsKey(n)) {
            count = countMap.get(n) + 1;
        } else {
            count = 1;
        }

        countMap.put(n, count);

        if (count > max) {
            max = count;
        }
    }

    for (final Map.Entry<Integer, Integer> tuple : countMap.entrySet()) {
        if (tuple.getValue() == max) {
            modes.add(tuple.getKey());
        }
    }

    return modes;
}

ADDITION

If you are using Java 8 or higher, you can also determine the modes like this:

public static List<Integer> getModes(final List<Integer> numbers) {
    final Map<Integer, Long> countFrequencies = numbers.stream()
            .collect(Collectors.groupingBy(Function.identity(), Collectors.counting()));

    final long maxFrequency = countFrequencies.values().stream()
            .mapToLong(count -> count)
            .max().orElse(-1);

    return countFrequencies.entrySet().stream()
            .filter(tuple -> tuple.getValue() == maxFrequency)
            .map(Map.Entry::getKey)
            .collect(Collectors.toList());
}

//Get
var p = $("#elementId");
var offset = p.offset();

//set
$("#secondElementId").offset({ top: offset.top, left: offset.left});

JSON.parse() function will do.

or

Using Jquery,

var obj = jQuery.parseJSON( '{ "name": "Vinod" }' );
alert( obj.name === "Vinod" );

I normally use Emacs (it has everything you need included).

Of course, there are other options available:

• Kile is KDE's LaTeX editor; it's excellent if you're just learning or if you prefer the integrated environment approach;
• Lyx is a WYSIWYG editor that uses LaTeX as a backend; i.e. you tell it what the text should look like and it generates the corresponding LaTeX

Cheers.

If the intention is adding the local/working copy to SVN, I used to do it the following way.

Note: I use the TortoiseSVN client and these steps assume that you already have the TortoiseSVN client installed.

1. I have a project (Test-4.2.2) in my local. I want to upload/add it to an SVN repository.
2. Using the TortoiseSVN repo-browser, I created an empty directory, "Test-4.2.2"
3. In my local I renamed the existing "Test-4.2.2" directory to "Test-4.2.2.1" (temporary)
4. Checkout the empty "Test-4.2.2" from SVN to your local
5. Copy all the sub-directories under 4.2.2.1 to this checkout directory 4.2.2
6. Now, right click "Test-4.2.2" and commit.
7. Delete the temp folder, "Test-4.2.2.1"

You can do both in code and XML. Only 4 basic things to be set.

1. shadow color
2. Shadow Dx - it specifies the X-axis offset of shadow. You can give -/+ values, where -Dx draws a shadow on the left of text and +Dx on the right
3. shadow Dy - it specifies the Y-axis offset of shadow. -Dy specifies a shadow above the text and +Dy specifies below the text.
4. shadow radius - specifies how much the shadow should be blurred at the edges. Provide a small value if shadow needs to be prominent. Else otherwise.

e.g.

    android:shadowColor="@color/text_shadow_color"
    android:shadowDx="-2"
    android:shadowDy="2"
    android:shadowRadius="0.01"

This draws a prominent shadow on left-lower side of text. In code, you can add something like this;

    TextView item = new TextView(getApplicationContext());
    item.setText(R.string.text);
    item.setTextColor(getResources().getColor(R.color.general_text_color));
    item.setShadowLayer(0.01f, -2, 2,   getResources().getColor(R.color.text_shadow_color));

If you're using the <Fade in> element for a react application please add key={} attribute in it as well or you'll see an error in the console.

this tiny jQuery plugin is very simple to use: https://github.com/finnlabs/jquery.observehashchange/

With Pathlib from python3 standard library:

Path(mypath).mkdir(parents=True, exist_ok=True)

If parents is true, any missing parents of this path are created as needed; they are created with the default permissions without taking mode into account (mimicking the POSIX mkdir -p command). If exist_ok is false (the default), an FileExistsError is raised if the target directory already exists.

If exist_ok is true, FileExistsError exceptions will be ignored (same behavior as the POSIX mkdir -p command), but only if the last path component is not an existing non-directory file.

Changed in version 3.5: The exist_ok parameter was added.

If you are certain that the script runs in the first hours of the day, you can simply do

  date -d "12 hours ago" '+%Y-%m-%d'

BTW, if the script runs daily at 00:35 (via crontab?) you should ask yourself what will happen if a DST change falls in that hour; the script could not run, or run twice in some cases. Modern implementations of cron are quite clever in this regard, though.

ES6 syntax with arrow function and interpolation:

var data=["a","b","c"];
$(data).each((index, element) => {
        console.log(`current index : ${index} element : ${element}`)
    });

I realise that this is an old thread but one option is just to remove the http: part from the image URL so that 'http://some/image.jpg' becomes '//some/image.jpg'. This will also work with CDNs

My guess is that the directory ~/bin/sbt/bin is not in your PATH.

To execute programs or scripts that are in the current directory you need to prefix the command with ./, as in:

./sbt

This is a security feature in linux, so to prevent overriding of system commands (and other programs) by a malicious party dropping a file in your home directory (for example). Imagine a script called 'ls' that emails your /etc/passwd file to 3rd party before executing the ls command... Or one that executes 'rm -rf .'...

That said, unless you need something specific from the latest source code, you're best off doing what paradigmatic said in his post, and install it from the Typesafe repository.

The constructor is called only once, so you can safely do what you want, however the disadvantage of calling methods from within the constructor, rather than directly, is that you don't get direct feedback if the method fails. This gets more difficult the more methods you call.

One solution is to provide methods that you can call to query the 'health' of the object once it's been constructed. For example the method isConfigOK() can be used to see if the config read operation was OK.

Another solution is to throw exceptions in the constructor upon failure, but it really depends on how 'fatal' these failures are.

class A
{
    Map <String,String> config = null;
    public A()
    {
        readConfig();
    }

    protected boolean readConfig()
    {
        ...
    }

    public boolean isConfigOK()
    {
        // Check config here
        return true;
    }
};

//a[contains(@prop,'Foo')]

Works if I use this XML to get results back.

<bla>
 <a prop="Foo1">a</a>
 <a prop="Foo2">b</a>
 <a prop="3Foo">c</a>
 <a prop="Bar">a</a>
</bla>

Edit: Another thing to note is that while the XPath above will return the correct answer for that particular xml, if you want to guarantee you only get the "a" elements in element "bla", you should as others have mentioned also use

/bla/a[contains(@prop,'Foo')]

This will search you all "a" elements in your entire xml document, regardless of being nested in a "blah" element

//a[contains(@prop,'Foo')]  

I added this for the sake of thoroughness and in the spirit of stackoverflow. :)

Find the pids of the processes you want to monitor and then use the -p option which allows you to provide a list of pids to the top command.

Example:

top -p 18884 -p 18892 -p 18919

  PID USER     PRI  NI  SIZE  RSS SHARE STAT %CPU %MEM   TIME CPU COMMAND
18884 user  25   0  672M  95M  9476 S     0.0  1.1   0:02   1 java
18892 user  25   0 2280M 123M 12252 S     0.0  1.5   0:05   1 java
18919 user  22   0 1492M 198M 28708 S     0.0  2.4   0:07   1 java

(I believe you can also pass in a comma-separated list.)

You could to this trick: create a file 1 hour ago, and use the -newer file argument.

(Or use touch -t to create such a file).

You should override __repr__ or __unicode__ methods instead of using message, the args you provide when you construct the exception will be in the args attribute of the exception object.

To prevent the build from also copying the Roslyn files to the bin directory, you have to also comment out this line that gets placed at the top of your Web application project:

<!--  <Import Project="..\..\..\DAS\packages\Microsoft.CodeDom.Providers.DotNetCompilerPlatform.1.0.1\build\Microsoft.CodeDom.Providers.DotNetCompilerPlatform.props" Condition="Exists('..\..\..\DAS\packages\Microsoft.CodeDom.Providers.DotNetCompilerPlatform.1.0.1\build\Microsoft.CodeDom.Providers.DotNetCompilerPlatform.props')" /> -->

Here is a very simple piece of C# code to test the CommandTimeout with. It creates a new command which will wait for 2 seconds. Set the CommandTimeout to 1 second and you will see an exception when running it. Setting the CommandTimeout to either 0 or something higher than 2 will run fine. By the way, the default CommandTimeout is 30 seconds.

      builder.DataSource = "localhost";
      builder.IntegratedSecurity = true;
      builder.InitialCatalog = "master";

      var connectionString = builder.ConnectionString;

      using (var connection = new SqlConnection(connectionString))
      {
        connection.Open();

        using (var command = connection.CreateCommand())
        {
          command.CommandText = "WAITFOR DELAY '00:00:02'";
          command.CommandTimeout = 1;

          command.ExecuteNonQuery();
        }
      }
    }
  }
}

I really think it's a more robust way to use getLocationOnScreen than getGlobalVisibleRect. Because I meet a problem. There is a Listview which contain some Edittext and and set ajustpan in the activity. I find getGlobalVisibleRect return a value that looks like including the scrollY in it, but the event.getRawY is always by the screen. The below code works well.

public boolean dispatchTouchEvent(MotionEvent event) {
    if (event.getAction() == MotionEvent.ACTION_DOWN) {
        View v = getCurrentFocus();
        if ( v instanceof EditText) {
            if (!isPointInsideView(event.getRawX(), event.getRawY(), v)) {
                Log.i(TAG, "!isPointInsideView");

                Log.i(TAG, "dispatchTouchEvent clearFocus");
                v.clearFocus();
                InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
                imm.hideSoftInputFromWindow(v.getWindowToken(), 0);
            }
        }
    }
    return super.dispatchTouchEvent( event );
}

I have created a demo for you.

Here is how your nested structure should be in Bootstrap 3:

<div class="form-group">
    <label for="birthday" class="col-xs-2 control-label">Birthday</label>
    <div class="col-xs-10">
        <div class="form-inline">
            <div class="form-group">
                <input type="text" class="form-control" placeholder="year"/>
            </div>
            <div class="form-group">
                <input type="text" class="form-control" placeholder="month"/>
            </div>
            <div class="form-group">
                <input type="text" class="form-control" placeholder="day"/>
            </div>
        </div>
    </div>
</div>

Notice how the whole form-inline is nested within the col-xs-10 div containing the control of the horizontal form. In other terms, the whole form-inline is the "control" of the birthday label in the main horizontal form.

Note that you will encounter a left and right margin problem by nesting the inline form within the horizontal form. To fix this, add this to your css:

.form-inline .form-group{
    margin-left: 0;
    margin-right: 0;
}

if ($inputs['type'] == 'attach') {

The code is valid, but it expects the function parameter $inputs to be an array. The "Illegal string offset" warning when using $inputs['type'] means that the function is being passed a string instead of an array. (And then since a string offset is a number, 'type' is not suitable.)

So in theory the problem lies elsewhere, with the caller of the code not providing a correct parameter.

However, this warning message is new to PHP 5.4. Old versions didn't warn if this happened. They would silently convert 'type' to 0, then try to get character 0 (the first character) of the string. So if this code was supposed to work, that's because abusing a string like this didn't cause any complaints on PHP 5.3 and below. (A lot of old PHP code has experienced this problem after upgrading.)

You might want to debug why the function is being given a string by examining the calling code, and find out what value it has by doing a var_dump($inputs); in the function. But if you just want to shut the warning up to make it behave like PHP 5.3, change the line to:

if (is_array($inputs) && $inputs['type'] == 'attach') {

Try this :)

    <script type="text/javascript" src="http://www.google.com/jsapi"></script>
    <script type="text/javascript">
    function initialize() {
        var loc = {};
        var geocoder = new google.maps.Geocoder();
        if(google.loader.ClientLocation) {
            loc.lat = google.loader.ClientLocation.latitude;
            loc.lng = google.loader.ClientLocation.longitude;

            var latlng = new google.maps.LatLng(loc.lat, loc.lng);
            geocoder.geocode({'latLng': latlng}, function(results, status) {
                if(status == google.maps.GeocoderStatus.OK) {
                    alert(results[0]['formatted_address']);
                };
            });
        }
    }

You may have more than one org.springframework.beans.factory.config.PropertyPlaceholderConfigurer in your application. Try setting a breakpoint on the setLocations method of the superclass and see if it's called more than once at application startup. If there is more than one org.springframework.beans.factory.config.PropertyPlaceholderConfigurer, you might need to look at configuring the ignoreUnresolvablePlaceholders property so that your application will start up cleanly.

I'm thinking maybe run doCalculations; echo "$?" >>/tmp/acc in a subshell that is sent to the background, then the wait, then /tmp/acc would contain the exit statuses, one per line. I don't know about any consequences of the multiple processes appending to the accumulator file, though.

Here's a trial of this suggestion:

File: doCalcualtions

#!/bin/sh

random -e 20
sleep $?
random -e 10

File: try

#!/bin/sh

rm /tmp/acc

for i in $( seq 0 20 ) 
do
        ( ./doCalculations "$i"; echo "$?" >>/tmp/acc ) &
done

wait

cat /tmp/acc | fmt
rm /tmp/acc

Output of running ./try

5 1 9 6 8 1 2 0 9 6 5 9 6 0 0 4 9 5 5 9 8

Just an alternative to the code by rkosegi,

BEGIN

Faster is not an attribute of JSON or XML or a result that a comparison between those would yield. If any, then it is an attribute of the parsers or the bandwidth with which you transmit the data.

Here is (the beginning of) a list of advantages and disadvantages of JSON and XML:

JSON

Pro:

• Simple syntax, which results in less "markup" overhead compared to XML.
• Easy to use with JavaScript as the markup is a subset of JS object literal notation and has the same basic data types as JavaScript.
• JSON Schema for description and datatype and structure validation
• JsonPath for extracting information in deeply nested structures

Con:

• Simple syntax, only a handful of different data types are supported.

• No support for comments.

XML

Pro:

• Generalized markup; it is possible to create "dialects" for any kind of purpose
• XML Schema for datatype, structure validation. Makes it also possible to create new datatypes
• XSLT for transformation into different output formats
• XPath/XQuery for extracting information in deeply nested structures
• built in support for namespaces

Con:

• Relatively wordy compared to JSON (results in more data for the same amount of information).

So in the end you have to decide what you need. Obviously both formats have their legitimate use cases. If you are mostly going to use JavaScript then you should go with JSON.

Please feel free to add pros and cons. I'm not an XML expert ;)

Is maching set to CASE_INSENSITIVE?

Here is what you are looking for:

Service hangs up at WaitForExit after calling batch file

It's about a question as to why a service can't execute a file, but it shows all the code necessary to do so.

ArrayList: ArrayList has a structure like an array, it has a direct reference to every element. So rendom access is fast in ArrayList.

LinkedList: In LinkedList for getting nth elemnt you have to traverse whole list, takes time as compared to ArrayList. Every element has a link to its previous & nest element, so deletion is fast.

switch (String.valueOf(value)){
    case "null":
    default: 
}

There are a couple of different ways you can do this:

1. Make the other script executable, add the #!/bin/bash line at the top, and the path where the file is to the $PATH environment variable. Then you can call it as a normal command;

2. Or call it with the source command (alias is .) like this: source /path/to/script;

3. Or use the bash command to execute it: /bin/bash /path/to/script;

The first and third methods execute the script as another process, so variables and functions in the other script will not be accessible.
The second method executes the script in the first script's process, and pulls in variables and functions from the other script so they are usable from the calling script.

In the second method, if you are using exit in second script, it will exit the first script as well. Which will not happen in first and third methods.

I don't believe you can do just a string, but if you put the string inside of a <span> with the correct attributes (size, font-weight, etc); you should then be able to use jQuery to get the width of the span.

<span id='string_span' style='font-weight: bold; font-size: 12'>Here is my string</span>
<script>
  $('#string_span').width();
</script>

If anyone gets this issue while using the integrated terminal in Visual Studio Code then there is a good chance it's updating. Restart Visual Studio Code and you will likely see the "New Version" tab and it should all start working again.

click on window tab and click on preferences

do this and check show line number

The problem with many answers here is that "\r\n\r\n" can legitimately appear in the body of the html, so you can't be sure that you're splitting headers correctly.

It seems that the only way to store headers separately with one call to curl_exec is to use a callback as is suggested above in https://stackoverflow.com/a/25118032/3326494

And then to (reliably) get just the body of the request, you would need to pass the value of the Content-Length header to substr() as a negative start value.

The anaconda functions are not exported by default, it can be done by using the following command:

$ source ~/anaconda3/etc/profile.d/conda.sh $ conda activate my_env

You can use

ng-bind-html https://docs.angularjs.org/api/ng/service/$sce

directive to bind html dynamically. However you have to get the data via $sce service.

Please see the live demo at http://plnkr.co/edit/k4s3Bx

var app = angular.module('plunker', []);
app.controller('MainCtrl', function($scope,$sce) {
    $scope.getHtml=function(){
   return $sce.trustAsHtml("<b>Hi Rupesh hi <u>dfdfdfdf</u>!</b>sdafsdfsdf<button>dfdfasdf</button>");
   }
});

  <body ng-controller="MainCtrl">
<span ng-bind-html="getHtml()"></span>
  </body>

What if javascript is Turned Off on clients machine? Use following solution for all scenarios. You dont even need javascript/jQuery. :

HTML

<label for="fileInput"><img src="File_upload_Img"><label>
<input type="file" id="fileInput"></label>

CSS

#fileInput{opacity:0}  
body{
    background:cadetblue;
}

Explanation : for="Your input Id" . Triggers click event by default by HTML. So it by default triggers click event, no need of jQuery/javascript. If its simply done by HTML why use jQuery/jScript? And you cant tell if client disabled JS. Your feature should work even though JS is turned off.

maybe map, but since you don't want to make a list, you can write your own...

def call_for_all(f, seq):
    for i in seq:
        f(i)

then you can do:

call_for_all(lamda x: x.start(), all)
call_for_all(lamda x: x.stop(), all)

by the way, all is a built in function, don't overwrite it ;-)
