ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

And then install wget with brew and also enable openressl for TLS support

brew install wget --with-libressl

It worked perfectly for me.

I know I'm a little late, but something I found that works (and doesn't require using csv) is to write a for loop that writes to your file for every element in your list.

# Define Data
RESULTS = ['apple','cherry','orange','pineapple','strawberry']

# Open File
resultFyle = open("output.csv",'w')

# Write data to file
for r in RESULTS:
    resultFyle.write(r + "\n")
resultFyle.close()

I don't know if this solution is any better than the ones already offered, but it more closely reflects your original logic so I thought I'd share.

There is no one better solution; however, I would like to argue that double quotes may be more desirable at times:

• Newcomers will already be familiar with double quotes from their language. In English, we must use double quotes " to identify a passage of quoted text. If we were to use a single quote ', the reader may misinterpret it as a contraction. The other meaning of a passage of text surrounded by the ' indicates the 'colloquial' meaning. It makes sense to stay consistent with pre-existing languages, and this may likely ease the learning and interpretation of code.
• Double quotes eliminate the need to escape apostrophes (as in contractions). Consider the string: "I'm going to the mall", vs. the otherwise escaped version: 'I\'m going to the mall'.

• Double quotes mean a string in many other languages. When you learn a new language like Java or C, double quotes are always used. In Ruby, PHP and Perl, single-quoted strings imply no backslash escapes while double quotes support them.

• JSON notation is written with double quotes.

Nonetheless, as others have stated, it is most important to remain consistent.

Simplest solution without extra extensions, enums, classes and etc.:

NSException(name:NSExceptionName(rawValue: "name"), reason:"reason", userInfo:nil).raise()

Try to add this:

^[^a-zA-Z\d\s:]*$

This has worked for me... :)

Another approach depending on how you are changing the div. If you are using JQuery to change a div's contents with its html() method, you can extend that method and call a registration function each time you put html into a div.

(function( $, oldHtmlMethod ){
    // Override the core html method in the jQuery object.
    $.fn.html = function(){
        // Execute the original HTML method using the
        // augmented arguments collection.

        var results = oldHtmlMethod.apply( this, arguments );
        com.invisibility.elements.findAndRegisterElements(this);
        return results;

    };
})( jQuery, jQuery.fn.html );

We just intercept the calls to html(), call a registration function with this, which in the context refers to the target element getting new content, then we pass on the call to the original jquery.html() function. Remember to return the results of the original html() method, because JQuery expects it for method chaining.

For more info on method overriding and extension, check out http://www.bennadel.com/blog/2009-Using-Self-Executing-Function-Arguments-To-Override-Core-jQuery-Methods.htm, which is where I cribbed the closure function. Also check out the plugins tutorial at JQuery's site.

You need to remove the

min-height:440px;

to

height:440px;

and then add

overflow: auto;

property to the class of the required div

Same case here, but nothing about comments posted it's right in my case, I have only one branch (master) and only use Unix file system, this error occur randomly when I run git fetch --progress --prune origin and branch is ahead or 'origin/master'. Nobody can commit, only 1 user can do push.

NOTE: I have a submodule in acme repository, and acme have new submodule changes (new commits), I need first do a submodule update with git submodule update.

To solve this problem (in my case) simply run first git push if your branch is ahead of origin.

You should check the EOF after reading from file.

fscanf_s                   // read from file
while(condition)           // check EOF
{
   fscanf_s               // read from file
}

Because of the thousand separator, the data will have been read as 'non-numeric'. So you need to convert it:

 we <- gsub(",", "", we)   # remove comma
 we <- as.numeric(we)      # turn into numbers

and now you can do

 hist(we)

and other numeric operations.

You can use the curl_error() function to detect if there was some error. For example:

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $your_url);
curl_setopt($ch, CURLOPT_FAILONERROR, true); // Required for HTTP error codes to be reported via our call to curl_error($ch)
//...
curl_exec($ch);
if (curl_errno($ch)) {
    $error_msg = curl_error($ch);
}
curl_close($ch);

if (isset($error_msg)) {
    // TODO - Handle cURL error accordingly
}

See the description of libcurl error codes here

See the description of PHP curl_errno() function here

See the description of PHP curl_error() function here

Attribute_Brands is a named range.

On any worksheet (tab) press F5 and type Attribute_Brands into the reference box and click on the OK button.

This will take you to the named range.

The data in it can be updated by typing new values into the cells.

The named range can be altered via the 'Insert - Name - Define' menu.

In some cases (e.g. unique list elements), set operations can be used.

>>> a=[2,3,4]
>>> set(a) - set([2,3]) != set(a)
True
>>> 

Or, using set.isdisjoint(),

>>> not set(a).isdisjoint(set([2,3]))
True
>>> not set(a).isdisjoint(set([5,6]))
False
>>>

drv.ExecuteScript("return alert(document.title);");

The Collections.sort is a good sort implementation. If you don't have The comparable implemented for Contact, you will need to pass in a Comparator implementation

Of note:

The sorting algorithm is a modified mergesort (in which the merge is omitted if the highest element in the low sublist is less than the lowest element in the high sublist). This algorithm offers guaranteed n log(n) performance. The specified list must be modifiable, but need not be resizable. This implementation dumps the specified list into an array, sorts the array, and iterates over the list resetting each element from the corresponding position in the array. This avoids the n2 log(n) performance that would result from attempting to sort a linked list in place.

The merge sort is probably better than most search algorithm you can do.

That's not possible with CSS, you will have to use the Javascript for that. Although you can set the width of the p to as much as 30 characters and next letters will automatically come down but again this won't be that accurate and will vary if the characters are in capital.

You could try a different approach like read the file line by line instead of dealing with all this nl2br / explode stuff.

$fh = fopen("employees.txt", "r"); if ($fh) {     while (($line = fgets($fh)) !== false) {         $line = trim($line);         echo "<option value='".$line."'>".$line."</option>";     } } else {     // error opening the file, do something } 

Also maybe just doing a trim (remove whitespace from beginning/end of string) is your issue?

And maybe people are just misunderstanding what you mean by "submitting results to a spreadsheet" -- are you doing this with code? or a copy/paste from an HTML page into a spreadsheet? Maybe you can explain that in more detail. The delimiter for which you split the lines of the file shouldn't be displaying in the output anyway unless you have unexpected output for some other reason.

- Here its more about the coding style than being the functionality....

- The 1st option is very clear, but then the 2nd one is quite elegant... no offense, its just my view..

Anything in the public folder is accessible at the root path (/) so change your img tag to read:

<img src="/images/rss.jpg" alt="rss feed" />

If you wanted to use a rails tag, use this:

<%= image_tag("rss.jpg", :alt => "rss feed") %>

document.getElementsByClassName returns an HTMLCollection(an array-like object) of all elements matching the class name. The style property is defined for Element not for HTMLCollection. You should access the first element using the bracket(subscript) notation.

document.getElementsByClassName('appBanner')[0].style.visibility = 'hidden';

Updated jsFiddle

To change the style rules of all elements matching the class, using the Selectors API:

[].forEach.call(document.querySelectorAll('.appBanner'), function (el) {
  el.style.visibility = 'hidden';
});

If for...of is available:

for (let el of document.querySelectorAll('.appBanner')) el.style.visibility = 'hidden';

I don't think desc takes an na.rm argument... I'm actually surprised it doesn't throw an error when you give it one. If you just want to remove NAs, use na.omit (base) or tidyr::drop_na:

outcome.df %>%
  na.omit() %>%
  group_by(Hospital, State) %>%
  arrange(desc(HeartAttackDeath)) %>%
  head()

library(tidyr)
outcome.df %>%
  drop_na() %>%
  group_by(Hospital, State) %>%
  arrange(desc(HeartAttackDeath)) %>%
  head()

If you only want to remove NAs from the HeartAttackDeath column, filter with is.na, or use tidyr::drop_na:

outcome.df %>%
  filter(!is.na(HeartAttackDeath)) %>%
  group_by(Hospital, State) %>%
  arrange(desc(HeartAttackDeath)) %>%
  head()

outcome.df %>%
  drop_na(HeartAttackDeath) %>%
  group_by(Hospital, State) %>%
  arrange(desc(HeartAttackDeath)) %>%
  head()

As pointed out at the dupe, complete.cases can also be used, but it's a bit trickier to put in a chain because it takes a data frame as an argument but returns an index vector. So you could use it like this:

outcome.df %>%
  filter(complete.cases(.)) %>%
  group_by(Hospital, State) %>%
  arrange(desc(HeartAttackDeath)) %>%
  head()

There are differences, but they are probably not relevant to your question. For example, the toString prototype does not exist on undefined variables, but you can cast undefined to a string using the other two methods:

?var foo;

?var myString1 = String(foo); // "undefined" as a string

var myString2 = foo + ''; // "undefined" as a string

var myString3 = foo.toString(); // throws an exception

Great question and great idea, but in SQL you'll need to do this:

For data type datetime, something like this-

declare @BeginDate    datetime = '1/1/2016',
        @EndDate      datetime = '12/1/2016'
create table #months (dates datetime)
declare @var datetime = @BeginDate
   while @var < dateadd(MONTH, +1, @EndDate)
   Begin
          insert into #months Values(@var)
          set @var = Dateadd(MONTH, +1, @var)
   end

If all you really want is numbers, do this-

create table #numbas (digit int)
declare @var int = 1        --your starting digit
    while @var <= 12        --your ending digit
    begin
        insert into #numbas Values(@var)
        set @var = @var +1
    end

Another way:

a xls(x) file is just a collection of *.xml files stored in a *.zip container. unzip the file "app.xml" in the folder docProps.

<?xml version="1.0" encoding="UTF-8" standalone="true"?>

    </vt:variant>
    -<vt:variant>
      <vt:i4>4</vt:i4>
    </vt:variant>
  </vt:vector>
</HeadingPairs>
-<TitlesOfParts>
  -<vt:vector baseType="lpstr" size="4">
    <vt:lpstr>Tabelle3</vt:lpstr>
    <vt:lpstr>Tabelle4</vt:lpstr>
    <vt:lpstr>Tabelle1</vt:lpstr>
    <vt:lpstr>Tabelle2</vt:lpstr>
  </vt:vector>
</TitlesOfParts>
<Company/>
<LinksUpToDate>false</LinksUpToDate>
<SharedDoc>false</SharedDoc>
<HyperlinksChanged>false</HyperlinksChanged>
<AppVersion>14.0300</AppVersion>
</Properties>

The file is a german file (Arbeitsblätter = worksheets). The table names (Tabelle3 etc) are in the correct order. You just need to read these tags;)

Better Approach:

<script type="text/javascript">
    $('#btn').click(function() {
      var id = $(this).attr('id');
      alert(id);
    });
</script>

<input id="btn" type="button" value="click" />

But, if you REALLY need to do the click handler inline, this will work:

<script type="text/javascript">
    function display(el) {
        var id = $(el).attr('id');
        alert(id);
    }
</script>

<input id="btn" type="button" value="click" OnClick="display(this);" />

Class Meta is the place in your code logic where your model.fields MEET With your form.widgets. So under Class Meta() you create the link between your model' fields and the different widgets you want to have in your form.

This issue happened in my project because of an ajax GET call with a long xml string as a parameter value. Solved by the following approach: Making it as ajax post call to Java Spring MVC controller class method like this.

$.ajax({
    url: "controller_Method_Name.html?variable_name="+variable_value,
    type: "POST",
    data:{ 
            "xmlMetaData": xmlMetaData // This variable contains a long xml string
    },
    success: function(response)
    {
        console.log(response);
    }
  });

Inside Spring MVC Controller class method:

@RequestMapping(value="/controller_Method_Name")
  public void controller_Method_Name(@RequestParam("xmlMetaData") String metaDataXML, HttpServletRequest request)
{
   System.out.println(metaDataXML);
}

it does not require much configurations just go to advanced system settings copy the path where you have installed your node and just create an environment variable and check with node -v command in your prompt!

See this question: JADE + EXPRESS: Iterating over object in inline JS code (client-side)?

I'm having the same problem. Jade does not pass local variables in (or do any templating at all) to javascript scripts, it simply passes the entire block in as literal text. If you use the local variables 'address' and 'port' in your Jade file above the script tag they should show up.

Possible solutions are listed in the question I linked to above, but you can either: - pass every line in as unescaped text (!= at the beginning of every line), and simply put "-" before every line of javascript that uses a local variable, or: - Pass variables in through a dom element and access through JQuery (ugly)

Is there no better way? It seems the creators of Jade do not want multiline javascript support, as shown by this thread in GitHub: https://github.com/visionmedia/jade/pull/405

Add this style to your span:

As of Excel 2019 you could do this. The "Error" at the end is the default.

Try this.

public static void main(String[] args) {

What you were trying to do was declaring a variable of type Object, not creating anything for that variable to reference, then trying to call a method that didn't exist (in the class Object) on an object that hadn't been created. It was never going to work.

The issue is basically coming when, we are requesting to angular to run the digest cycle even though its in process which is creating issue to angular to understanding. consequence exception in console.
1. It does not have any sense to call scope.$apply() inside the $timeout function because internally it does the same.
2. The code goes with vanilla JavaScript function because its native not angular angular defined i.e. setTimeout

if(!scope.$$phase){
scope.$evalAsync(function(){

}); }

My syntax error was semi-hidden in an f-string

should be

It didn't have the PyCharm spell-check-red line under the error.

It did give me a clue, yet when I searched on this error message, it of course did not find the error in that bit of code above.

Had I looked more closely at the error message, I would have found the '' in the error. Seeing Line 1 was discouraging and thus wasn't paying close attention :-( Searching for

self.)

yielded nothing. Searching for

self.

yielded practically everything :-\

If I can help you avoid even a minute longer of deskchecking your code, then mission accomplished :-)

A process consists of at least one thread (think of the main function). Multi threaded code will just spawn more threads. Mutexes are used to create locks around shared resources to avoid data corruption / unexpected / unwanted behaviour. Basically it provides for sequential execution in an asynchronous setup - the requirement for which stems from non-const non-atomic operations on shared data structures.

A vivid description of what mutexes would be the case of people (threads) queueing up to visit the restroom (shared resource). While one person (thread) is using the bathroom easing him/herself (non-const non-atomic operation), he/she should ensure the door is locked (mutex), otherwise it could lead to being caught in full monty (unwanted behaviour)

You can generate an AWR (automatic workload repository) report from the database.

Run from the SQL*Plus command line:

SQL> @$ORACLE_HOME/rdbms/admin/awrrpt.sql

Read the document related to how to generate & understand an AWR report. It will give a complete view of database performance and resource issues. Once we are familiar with the AWR report it will be helpful to find Top SQL which is consuming resources.

Also, in the 12C EM Express UI we can generate an AWR.

var array = $('#searchKeywords').val().split(",");

then

$.each(array,function(i){
   alert(array[i]);
});

OR

for (i=0;i<array.length;i++){
     alert(array[i]);
}

Just change your syntax ever so slightly:

CASE WHEN STATE = 2 AND RetailerProcessType = 1 THEN '"AUTHORISED"'
     WHEN STATE = 1 AND RetailerProcessType = 2 THEN '"PENDING"'
     WHEN STATE = 2 AND RetailerProcessType = 2 THEN '"AUTHORISED"'
     ELSE '"DECLINED"'
END

If you don't put the field expression before the CASE statement, you can put pretty much any fields and comparisons in there that you want. It's a more flexible method but has slightly more verbose syntax.

Like this:

printf("hello%%");
//-----------^^ inside printf, use two percent signs together

I just done this with swift4 by adding 3 gestures together in single view

1. UIPinchGestureRecognizer : Zoom in and zoom out view.
2. UIRotationGestureRecognizer : Rotate the view.
3. UIPanGestureRecognizer : Dragging the view.

Here my sample code

class ViewController: UIViewController: UIGestureRecognizerDelegate{
      //your image view that outlet from storyboard or xibs file.
     @IBOutlet weak var imgView: UIImageView!
     // declare gesture recognizer
     var panRecognizer: UIPanGestureRecognizer?
     var pinchRecognizer: UIPinchGestureRecognizer?
     var rotateRecognizer: UIRotationGestureRecognizer?

     override func viewDidLoad() {
          super.viewDidLoad()
          // Create gesture with target self(viewcontroller) and handler function.  
          self.panRecognizer = UIPanGestureRecognizer(target: self, action: #selector(self.handlePan(recognizer:)))
          self.pinchRecognizer = UIPinchGestureRecognizer(target: self, action: #selector(self.handlePinch(recognizer:)))
          self.rotateRecognizer = UIRotationGestureRecognizer(target: self, action: #selector(self.handleRotate(recognizer:)))
          //delegate gesture with UIGestureRecognizerDelegate
          pinchRecognizer?.delegate = self
          rotateRecognizer?.delegate = self
          panRecognizer?.delegate = self
          // than add gesture to imgView
          self.imgView.addGestureRecognizer(panRecognizer!)
          self.imgView.addGestureRecognizer(pinchRecognizer!)
          self.imgView.addGestureRecognizer(rotateRecognizer!)
     }

     // handle UIPanGestureRecognizer 
     @objc func handlePan(recognizer: UIPanGestureRecognizer) {    
          let gview = recognizer.view
          if recognizer.state == .began || recognizer.state == .changed {
               let translation = recognizer.translation(in: gview?.superview)
               gview?.center = CGPoint(x: (gview?.center.x)! + translation.x, y: (gview?.center.y)! + translation.y)
               recognizer.setTranslation(CGPoint.zero, in: gview?.superview)
          }
     }

     // handle UIPinchGestureRecognizer

Any question, just type to comment. thank you

I have changed it in the following steps:

1) please add this dependency on your pubspec.yaml page

 dev_dependencies:
  flutter_test:
    sdk: flutter
  flutter_launcher_icons: ^0.7.4

2) you have to upload an image/icon on your project which you want to see as a launcher icon. (i have created a folder name:image in my project then upload the logo.png in the image folder). Now you have to add the below codes and paste your image path on image_path: in pubspec.yaml page.

flutter_icons:
  image_path: "images/logo.png"
  android: true
  ios: true

3) Go to terminal and execute this command:

flutter pub get

4) After executing the command then enter below command:

flutter pub run flutter_launcher_icons:main

5) Done

N.B: (of course add an updated dependency from

https://pub.dev/packages/flutter_launcher_icons#-installing-tab-

)

Change:

using (RegistryKey key = Registry.LocalMachine.OpenSubKey("Software\\Wow6432Node\\MySQL AB\\MySQL Connector\\Net"))

To:

 using (RegistryKey key = Registry.LocalMachine.OpenSubKey("Software\Wow6432Node\MySQL AB\MySQL Connector\Net"))

If you have a pd.Series object x with index named 'Gene', you can use reset_index and supply the name argument:

df = x.reset_index(name='count')

Here's a demo:

x = pd.Series([2, 7, 1], index=['Ezh2', 'Hmgb', 'Irf1'])
x.index.name = 'Gene'

df = x.reset_index(name='count')

print(df)

   Gene  count
0  Ezh2      2
1  Hmgb      7
2  Irf1      1

This is a great article for syntax needed to create new objects from a LINQ query.

But, if the assignments to fill in the fields of the object are anything more than simple assignments, for example, parsing strings to integers, and one of them fails, it is not possible to debug this. You can not create a breakpoint on any of the individual assignments.

And if you move all the assignments to a subroutine, and return a new object from there, and attempt to set a breakpoint in that routine, you can set a breakpoint in that routine, but the breakpoint will never be triggered.

So instead of:

var query2 = from c in doc.Descendants("SuggestionItem")
                select new SuggestionItem
                       { Phrase = c.Element("Phrase").Value
                         Blocked = bool.Parse(c.Element("Blocked").Value),
                         SeenCount = int.Parse(c.Element("SeenCount").Value)
                       };

Or

var query2 = from c in doc.Descendants("SuggestionItem")
                         select new SuggestionItem(c);

I instead did this:

List<SuggestionItem> retList = new List<SuggestionItem>();

var query = from c in doc.Descendants("SuggestionItem") select c;

foreach (XElement item in query)
{
    SuggestionItem anItem = new SuggestionItem(item);
    retList.Add(anItem);
}

This allowed me to easily debug and figure out which assignment was failing. In this case, the XElement was missing a field I was parsing for to set in the SuggestionItem.

I ran into these gotchas with Visual Studio 2017 while writing unit tests for a new library routine.

++i: is pre-increment the other is post-increment.

i++: gets the element and then increments it.
++i: increments i and then returns the element.

Example:

int i = 0;
printf("i: %d\n", i);
printf("i++: %d\n", i++);
printf("++i: %d\n", ++i);

Output:

i: 0
i++: 0
++i: 2

The reason could be the firewall modification as you are under a network.(In which case they may deliberately block some ports)
To double check if this is the reason ... do

ssh -T [email protected]

this should timeout. If that's the case use http protocol instead of ssh this way
just change your url in the config file to http.
Here is how :-

git config --local -e

change entry of

 url = [email protected]:username/repo.git

to

url = https://github.com/username/repo.git

just convert denominator to decimal before division e.g

select col1 / CONVERT(decimal(4,2), col2) from tbl1

I think you haven't messed up yet. Try:

git reset HEAD^

This will bring the dir to state before you've made the commit, HEAD^ means the parent of the current commit (the one you don't want anymore), while keeping changes from it (unstaged).

Here is what the standard (SI) says:

http://physics.nist.gov/Pubs/SP330/sp330.pdf#page=34

The most compatible way of doing this is using tput to discover the right sequences to send to the terminal:

bold=$(tput bold)
normal=$(tput sgr0)

then you can use the variables $bold and $normal to format things:

echo "this is ${bold}bold${normal} but this isn't"

gives

this is bold but this isn't

You should set both your table encoding and connection encoding to UTF-8:

ALTER TABLE keywords CHARACTER SET UTF8; -- run once

and

SET NAMES 'UTF8';
SET CHARACTER SET 'UTF8';

You might be able to do something with sibling selectors e.g.:

div + div + div + div{
float: left
}

Not tried it but this might float the 4th div left perhaps doing what you want. Again not fully supported.

typedef union{
    float a;
    char b[4];
} my_union_t;

You can access to float data value byte by byte and send it through 8-bit output buffer (e.g. USART) without casting.

New in C# 8.0 you can use the so-called "hat" (^) operator! This is useful for when you want to do something in one line!

var mystr = "Hello World!";
var lastword = mystr.Split(" ")[^1];
Console.WriteLine(lastword);
// World!

instead of the old way:

var mystr = "Hello World";
var split = mystr.Split(" ");
var lastword = split[split.Length - 1];
Console.WriteLine(lastword);
// World!

It doesn't save much space, but it looks much clearer (maybe I only think this because I came from python?). This is also much better than calling a method like .Last() or .Reverse() Read more at MSDN

Edit: You can add this functionality to your class like so:

public class MyClass
{
  public object this[Index indx]
  {
    get
    {
      // Do indexing here, this is just an example of the .IsFromEnd property
      if (indx.IsFromEnd)
      {
        Console.WriteLine("Negative Index!")
      }
      else
      {
        Console.WriteLine("Positive Index!")
      }
    }
  }
}

The Index.IsFromEnd will tell you if someone is using the 'hat' (^) operator

See https://bootstrap.themes.guide/how-to-customize-bootstrap.html

1. For simple CSS Overrides, you can add a custom.css below the bootstrap.css

   <link rel="stylesheet" type="text/css" href="css/bootstrap.min.css">
   <link rel="stylesheet" type="text/css" href="css/custom.css">
   

2. For more extensive changes, SASS is the recommended method.

   • create your own custom.scss
   • import Bootstrap after the changes in custom.scss

   • For example, let’s change the body background-color to light-gray #eeeeee, and change the blue primary contextual color to Bootstrap's $purple variable...

     /* custom.scss */    
     
     /* import the necessary Bootstrap files */
     @import "bootstrap/functions";
     @import "bootstrap/variables";
     
     /* -------begin customization-------- */   
     
     /* simply assign the value */ 
     $body-bg: #eeeeee;
     
     /* or, use an existing variable */
     $theme-colors: (
       primary: $purple
     );
     /* -------end customization-------- */  
     
     /* finally, import Bootstrap to set the changes! */
     @import "bootstrap";
     

For Windows, when you install a package, you type:

python -m pip install [packagename]

You could just inline a generator to filter out the null values if you want to pretend they don't exist. Of course this is assuming the null bytes are not really part of the encoding and really are some kind of erroneous artifact or bug.

See the (line.replace('\0','') for line in f) below, also you'll want to probably open that file up using mode rb.

import csv

lines = []
with open('output.txt','r') as f:
    for line in f.readlines():
        lines.append(line[:-1])

with open('corrected.csv','w') as correct:
    writer = csv.writer(correct, dialect = 'excel')
    with open('input.csv', 'rb') as mycsv:
        reader = csv.reader( (line.replace('\0','') for line in mycsv) )
        for row in reader:
            if row[0] not in lines:
                writer.writerow(row)

When you create a folder with N entries, you create a list of N items at file-system level. This list is a system-wide shared data structure. If you then start modifying this list continuously by adding/removing entries, I expect at least some lock contention over shared data. This contention - theoretically - can negatively affect performance.

For read-only scenarios I can't imagine any reason for performance degradation of directories with large number of entries.

 var input= $(this);    
 input.innerHTML = '';

Adding the below code helped me overcome the issue.

ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls11;

Maybe this can help you:

import random
for a in range(64,90):
    h = random.randint(64, a)
    e += chr(h)
print e

The correct answer is

git checkout -m origin/master

It merges changes from the origin master branch with your local even uncommitted changes.

what about changing the while loop to a do while loop

and exit using

Exit Do

In my particular case the function was actually missing. The error message is the same. I am using the Postgresql plugin PostGIS and I had to reinstall that for whatever reason.

If you want to add REM at the beginning of each line instead of using GOTO, you can use Notepad++ to do this easily following these steps:

1. Select the block of lines
2. hit Ctrl-Q

Repeat steps to uncomment

Another option:

$(el).trigger({type: 'keypress', which: 13, keyCode: 13});

http://api.jquery.com/trigger/

Please try below code for it :

$('#msform').fadeOut(50);

$('#msform').fadeIn(50);

There is now an ELMAH.MVC package in NuGet that includes an improved solution by Atif and also a controller that handles the elmah interface within MVC routing (no need to use that axd anymore)
The problem with that solution (and with all the ones here) is that one way or another the elmah error handler is actually handling the error, ignoring what you might want to set up as a customError tag or through ErrorHandler or your own error handler
The best solution IMHO is to create a filter that will act at the end of all the other filters and log the events that have been handled already. The elmah module should take care of loging the other errors that are unhandled by the application. This will also allow you to use the health monitor and all the other modules that can be added to asp.net to look at error events

I wrote this looking with reflector at the ErrorHandler inside elmah.mvc

public class ElmahMVCErrorFilter : IExceptionFilter
{
   private static ErrorFilterConfiguration _config;

   public void OnException(ExceptionContext context)
   {
       if (context.ExceptionHandled) //The unhandled ones will be picked by the elmah module
       {
           var e = context.Exception;
           var context2 = context.HttpContext.ApplicationInstance.Context;
           //TODO: Add additional variables to context.HttpContext.Request.ServerVariables for both handled and unhandled exceptions
           if ((context2 == null) || (!_RaiseErrorSignal(e, context2) && !_IsFiltered(e, context2)))
           {
            _LogException(e, context2);
           }
       }
   }

   private static bool _IsFiltered(System.Exception e, System.Web.HttpContext context)
   {
       if (_config == null)
       {
           _config = (context.GetSection("elmah/errorFilter") as ErrorFilterConfiguration) ?? new ErrorFilterConfiguration();
       }
       var context2 = new ErrorFilterModule.AssertionHelperContext((System.Exception)e, context);
       return _config.Assertion.Test(context2);
   }

   private static void _LogException(System.Exception e, System.Web.HttpContext context)
   {
       ErrorLog.GetDefault((System.Web.HttpContext)context).Log(new Elmah.Error((System.Exception)e, (System.Web.HttpContext)context));
   }


   private static bool _RaiseErrorSignal(System.Exception e, System.Web.HttpContext context)
   {
       var signal = ErrorSignal.FromContext((System.Web.HttpContext)context);
       if (signal == null)
       {
           return false;
       }
       signal.Raise((System.Exception)e, (System.Web.HttpContext)context);
       return true;
   }
}

Now, in your filter config you want to do something like this:

    public static void RegisterGlobalFilters(GlobalFilterCollection filters)
    {
        //These filters should go at the end of the pipeline, add all error handlers before
        filters.Add(new ElmahMVCErrorFilter());
    }

Notice that I left a comment there to remind people that if they want to add a global filter that will actually handle the exception it should go BEFORE this last filter, otherwise you run into the case where the unhandled exception will be ignored by the ElmahMVCErrorFilter because it hasn't been handled and it should be loged by the Elmah module but then the next filter marks the exception as handled and the module ignores it, resulting on the exception never making it into elmah.

Now, make sure the appsettings for elmah in your webconfig look something like this:

<add key="elmah.mvc.disableHandler" value="false" /> <!-- This handles elmah controller pages, if disabled elmah pages will not work -->
<add key="elmah.mvc.disableHandleErrorFilter" value="true" /> <!-- This uses the default filter for elmah, set to disabled to use our own -->
<add key="elmah.mvc.requiresAuthentication" value="false" /> <!-- Manages authentication for elmah pages -->
<add key="elmah.mvc.allowedRoles" value="*" /> <!-- Manages authentication for elmah pages -->
<add key="elmah.mvc.route" value="errortracking" /> <!-- Base route for elmah pages -->

The important one here is "elmah.mvc.disableHandleErrorFilter", if this is false it will use the handler inside elmah.mvc that will actually handle the exception by using the default HandleErrorHandler that will ignore your customError settings

This setup allows you to set your own ErrorHandler tags in classes and views, while still loging those errors through the ElmahMVCErrorFilter, adding a customError configuration to your web.config through the elmah module, even writing your own Error Handlers. The only thing you need to do is remember to not add any filters that will actually handle the error before the elmah filter we've written. And I forgot to mention: no duplicates in elmah.

I had the same problem while I was testing a project and it turned that running Fiddler was the cause for this error..!!

If you are using Fiddler to intercept the http request, shut it down ...

This is one of the many causes for such error.

To fix Fiddler you may need to Reset Fiddler Https Certificates.

Use jline3:

Example:

Terminal terminal = TerminalBuilder.builder()
    .jna(true)
    .system(true)
    .build();

// raw mode means we get keypresses rather than line buffered input
terminal.enterRawMode();
reader = terminal .reader();
...
int read = reader.read();
....
reader.close();
terminal.close();

Making your own itoa is also easy, try this :

char* itoa(int i, char b[]){
    char const digit[] = "0123456789";
    char* p = b;
    if(i<0){
        *p++ = '-';
        i *= -1;
    }
    int shifter = i;
    do{ //Move to where representation ends
        ++p;
        shifter = shifter/10;
    }while(shifter);
    *p = '\0';
    do{ //Move back, inserting digits as u go
        *--p = digit[i%10];
        i = i/10;
    }while(i);
    return b;
}

or use the standard sprintf() function.

As stated in the urllib2 documentation:

The urllib2 module has been split across several modules in Python 3 named urllib.request and urllib.error. The 2to3 tool will automatically adapt imports when converting your sources to Python 3.

So you should instead be saying

from urllib.request import urlopen
html = urlopen("http://www.google.com/").read()
print(html)

Your current, now-edited code sample is incorrect because you are saying urllib.urlopen("http://www.google.com/") instead of just urlopen("http://www.google.com/").

You would do

Person.where('name=? OR lastname=?', 'John', 'Smith')

Right now, there isn't any other OR support by the new AR3 syntax (that is without using some 3rd party gem).

def permutations(head, tail=''):
    if len(head) == 0:
        print(tail)
    else:
        for i in range(len(head)):
            permutations(head[:i] + head[i+1:], tail + head[i])

called as:

permutations('abc')

Xcode 9 • Swift 4 (also works Swift 3.x)

extension Formatter {
    // create static date formatters for your date representations
    static let preciseLocalTime: DateFormatter = {
        let formatter = DateFormatter()
        formatter.locale = Locale(identifier: "en_US_POSIX")
        formatter.dateFormat = "HH:mm:ss.SSS"
        return formatter
    }()
    static let preciseGMTTime: DateFormatter = {
        let formatter = DateFormatter()
        formatter.locale = Locale(identifier: "en_US_POSIX")
        formatter.timeZone = TimeZone(secondsFromGMT: 0)
        formatter.dateFormat = "HH:mm:ss.SSS"
        return formatter
    }()
}

extension Date {
    // you can create a read-only computed property to return just the nanoseconds from your date time
    var nanosecond: Int { return Calendar.current.component(.nanosecond,  from: self)   }
    // the same for your local time
    var preciseLocalTime: String {
        return Formatter.preciseLocalTime.string(for: self) ?? ""
    }
    // or GMT time
    var preciseGMTTime: String {
        return Formatter.preciseGMTTime.string(for: self) ?? ""
    }
}

Playground testing

Date().preciseLocalTime // "09:13:17.385"  GMT-3
Date().preciseGMTTime   // "12:13:17.386"  GMT
Date().nanosecond       // 386268973

This might help you also formatting your dates:

You can do in the following case,

CREATE PROCEDURE spDoSearch
   @FirstName varchar(25) = null,
   @LastName varchar(25) = null,
   @Title varchar(25) = null
AS
  BEGIN
      SELECT ID, FirstName, LastName, Title
      FROM tblUsers
      WHERE
        (@FirstName IS NULL OR FirstName = @FirstName) AND
        (@LastNameName IS NULL OR LastName = @LastName) AND
        (@Title IS NULL OR Title = @Title)
END

however depend on data sometimes better create dynamic query and execute them.

You could do this two different ways. One is by using "as"

has_many :tasks, :as => :jobs

or

def jobs
     self.tasks
end

Obviously the first one would be the best way to handle it.

The legitimate way to do that irrespective of size of the div for any browser size is :

   div{
    margin:auto;
    height: 200px;
    width: 200px;
    position:fixed;
    top:0;
    bottom:0;
    left:0;
    right:0;
    background:red;
   }

Live Code

I was running Asp.Net Web Api 5.2.7 and it looks like the JsonResult class has changed to use generics and an asynchronous execute method. I ended up altering Richard Garside's solution:

public class JsonHttpStatusResult<T> : JsonResult<T>
{
    private readonly HttpStatusCode _httpStatus;

    public JsonHttpStatusResult(T content, JsonSerializerSettings serializer, Encoding encoding, ApiController controller, HttpStatusCode httpStatus) 
    : base(content, serializer, encoding, controller)
    {
        _httpStatus = httpStatus;
    }

    public override Task<HttpResponseMessage> ExecuteAsync(CancellationToken cancellationToken)
    {
        var returnTask = base.ExecuteAsync(cancellationToken);
        returnTask.Result.StatusCode = HttpStatusCode.BadRequest;
        return returnTask;
    }
}

Following Richard's example, you could then use this class like this:

if(thereWereErrors)
{
    var errorModel = new CustomErrorModel("There was an error");
    return new JsonHttpStatusResult<CustomErrorModel>(errorModel, new JsonSerializerSettings(), new UTF8Encoding(), this, HttpStatusCode.InternalServerError);
}

Unfortunately, you can't use an anonymous type for the content, as you need to pass a concrete type (ex: CustomErrorType) to the JsonHttpStatusResult initializer. If you want to use anonymous types, or you just want to be really slick, you can build on this solution by subclassing ApiController to add an HttpStatusCode param to the Json methods :)

public abstract class MyApiController : ApiController
{
    protected internal virtual JsonHttpStatusResult<T> Json<T>(T content, HttpStatusCode httpStatus, JsonSerializerSettings serializerSettings, Encoding encoding)
    {
        return new JsonHttpStatusResult<T>(content, httpStatus, serializerSettings, encoding, this);
    }

    protected internal JsonHttpStatusResult<T> Json<T>(T content, HttpStatusCode httpStatus, JsonSerializerSettings serializerSettings)
    {
        return Json(content, httpStatus, serializerSettings, new UTF8Encoding());
    }

    protected internal JsonHttpStatusResult<T> Json<T>(T content, HttpStatusCode httpStatus)
    {
        return Json(content, httpStatus, new JsonSerializerSettings());
    }
}

Then you can use it with an anonymous type like this:

if(thereWereErrors)
{
    var errorModel = new { error = "There was an error" };
    return Json(errorModel, HttpStatusCode.InternalServerError);
}

To drop duplicate indices, use df = df.loc[df.index.drop_duplicates()]. C.f. pandas.pydata.org/pandas-docs/stable/generated/… – BallpointBen Apr 18 at 15:25

This is wrong but I can't reply directly to BallpointBen's comment due to low reputation. The reason its wrong is that df.index.drop_duplicates() returns a list of unique indices, but when you index back into the dataframe using those the unique indices it still returns all records. I think this is likely because indexing using one of the duplicated indices will return all instances of the index.

Instead, use df.index.duplicated(), which returns a boolean list (add the ~ to get the not-duplicated records):

df = df.loc[~df.index.duplicated()]

You have to use ':' colon instead of ';' semicolon.

As it stands now you try to execute the jar file which has not the execute bit set, hence the Permission denied.

And the variable must be CLASSPATH not classpath.

Yes; copy the string to a char array, sort the char array, then copy that back into a string.

static string SortString(string input)
{
    char[] characters = input.ToArray();
    Array.Sort(characters);
    return new string(characters);
}

I might be wrong but "find -name __" works fine for me. (Maybe it's just my phone.) If you just want to list all files, you can try

adb shell ls -R /

You probably need the root permission though.

Edit: As other answers suggest, use ls with grep like this:

adb shell ls -Ral yourDirectory | grep -i yourString

eg.

adb shell ls -Ral / | grep -i myfile

-i is for ignore-case. and / is the root directory.

The problem is that your PATH does not include the location of the node executable.

You can likely run node as "/usr/local/bin/node".

You can add that location to your path by running the following command to add a single line to your bashrc file:

echo 'export PATH=$PATH:/usr/local/bin' >> $HOME/.bashrc

Maybe I can still help somebody out who bumps into this question, because this is a very old issue.

I needed this as well and wrote a behavior to take care of this. So here is the behavior:

public class StretchMaxWidthBehavior : Behavior<FrameworkElement>
{        
    protected override void OnAttached()
    {
        base.OnAttached();
        ((FrameworkElement)this.AssociatedObject.Parent).SizeChanged += this.OnSizeChanged;
    }

    protected override void OnDetaching()
    {
        base.OnDetaching();
        ((FrameworkElement)this.AssociatedObject.Parent).SizeChanged -= this.OnSizeChanged;
    }

    private void OnSizeChanged(object sender, SizeChangedEventArgs e)
    {
        this.SetAlignments();
    }

    private void SetAlignments()
    {
        var slot = LayoutInformation.GetLayoutSlot(this.AssociatedObject);
        var newWidth = slot.Width;
        var newHeight = slot.Height;

        if (!double.IsInfinity(this.AssociatedObject.MaxWidth))
        {
            if (this.AssociatedObject.MaxWidth < newWidth)
            {
                this.AssociatedObject.HorizontalAlignment = HorizontalAlignment.Left;
                this.AssociatedObject.Width = this.AssociatedObject.MaxWidth;
            }
            else
            {
                this.AssociatedObject.HorizontalAlignment = HorizontalAlignment.Stretch;
                this.AssociatedObject.Width = double.NaN;
            }
        }

        if (!double.IsInfinity(this.AssociatedObject.MaxHeight))
        {
            if (this.AssociatedObject.MaxHeight < newHeight)
            {
                this.AssociatedObject.VerticalAlignment = VerticalAlignment.Top;
                this.AssociatedObject.Height = this.AssociatedObject.MaxHeight;
            }
            else
            {
                this.AssociatedObject.VerticalAlignment = VerticalAlignment.Stretch;
                this.AssociatedObject.Height = double.NaN;
            }
        }
    }
}

Then you can use it like so:

<Grid>
    <Grid.ColumnDefinitions>
        <ColumnDefinition Width="Auto" />
        <ColumnDefinition />
    </Grid.ColumnDefinitions>

    <TextBlock Grid.Column="0" Text="Label" />
    <TextBox Grid.Column="1" MaxWidth="600">
          <i:Interaction.Behaviors>                       
               <cbh:StretchMaxWidthBehavior/>
          </i:Interaction.Behaviors>
    </TextBox>
</Grid>

And finally to forget to use the System.Windows.Interactivity namespace to use the behavior.

I'm adding Bard Park's comment here for that was the real answer for me:

Since mvim is simply a shell script, you can download it directly from the MacVim source at GitHub here: http://raw.github.com/b4winckler/macvim/master/src/MacVim/mvim

If you wont to forward your ref, in Props interface you need to use RefObject<CmpType> type from import React, { RefObject } from 'react';

Ah I think a understand now. Have a look if this really is what you want:

$(".start").keyup(function(){
    $(this).closest('tr').find("input").each(function() {
        alert(this.value)
    });
});

This will give you all input values of a row.

Update:
To get the value of not all elements you can use :not():

$(this).closest('tr').find("input:not([name^=desc][name^=phone])").each(function() {
     alert(this.value)
});

Actually I am not 100% sure whether it works this way, maybe you have to use two nots instead of this one combining both conditions.

You should define source code encoding, add this to the top of your script:

# -*- coding: utf-8 -*-

The reason why it works differently in console and in the IDE is, likely, because of different default encodings set. You can check it by running:

import sys
print sys.getdefaultencoding()

Also see:

• Why declare unicode by string in python?
• Changing default encoding of Python?
• Correct way to define Python source code encoding

This is also working, avoiding to call for an element id but calling it using as an array element.

The following code is based on the fact that an array, named as the radiobuttons group, is composed by radiobuttons elements in the same order as they where declared in the html document:

if(!document.yourformname.yourradioname[0].checked 
   && !document.yourformname.yourradioname[1].checked){
    alert('is this working for all?');
    return false;
}

If you think you can use Javascript, then since jQuery support last-child, you can use jQuery's css method and the good thing it will support almost all the browsers

Example Code:

$(function(){
   $("#nav li:last-child").css("border-bottom","1px solid #b5b5b5")
})

Just for something to do, I refactored the top answer into a class. The usage is something like:

ConfigMan configMan = new ConfigMan(this.GetType().Assembly.Location);
var setting = configMan.GetAppSetting("AppSettingsKey");

Here is a table of the different events and the levels of browser support. You need to pick an event which is supported across at least all modern browsers.

As you will see from the table, the keypress and change event do not have uniform support whereas the keyup event does.

Also make sure you attach the event handler using a cross-browser-compatible method...

Another useful thing to do with numpy.histogram is to plot the output as the x and y coordinates on a linegraph. For example:

arr = np.random.randint(1, 51, 500)
y, x = np.histogram(arr, bins=np.arange(51))
fig, ax = plt.subplots()
ax.plot(x[:-1], y)
fig.show()

This can be a useful way to visualize histograms where you would like a higher level of granularity without bars everywhere. Very useful in image histograms for identifying extreme pixel values.

I found the answer!

I want to acknowledge the hard work of everyone in trying to find a better way to solve this problem, unfortunately because of a series of larger constraints I am unable to select them as the "answer" (I am voting them up because you deserve points for contributing).

The specific problem I was facing was a JavaScript onScoll event that was firing but a subsequent CSS update that wasn't causing IE8 (in standards mode) to redraw. Even stranger was the fact that in some pages it was redrawing while in others (with no obvious similarity) it wasn't. The solution in the end was to add the following CSS

#ActionBox {
  position: relative;
  float: right;
}

Here is an updated pastbin showing this (I added some more style to show how I am implementing this code). The IE "edit code" then "view output" bug fudgey talked about still occurs (but it seems to be a event binding issue unique to pastbin (and similar services)

I don't know why adding "float: right" allows IE8 to complete a redraw on an event that was already firing, but for some reason it does.

I wonder that nobody has mentioned this, But the easiest way of getting the last used cell is:

Function GetLastCell(sh as Worksheet) As Range
    GetLastCell = sh.Cells(1,1).SpecialCells(xlLastCell)
End Function

This essentially returns the same cell that you get by Ctrl + End after selecting Cell A1.

A word of caution: Excel keeps track of the most bottom-right cell that was ever used in a worksheet. So if for example you enter something in B3 and something else in H8 and then later on delete the contents of H8, pressing Ctrl + End will still take you to H8 cell. The above function will have the same behavior.

    for(int i=0; i<4; i++)
        cout << setprecision(3) << src.at<double>(0,i) << endl;

    return 0;
}

Oracle doesn't provide such IIF Function. Instead, try using one of the following alternatives:

DECODE Function:

SELECT DECODE(EMP_ID, 1, 'True', 'False') from Employee

CASE Function:

SELECT CASE WHEN EMP_ID = 1 THEN 'True' ELSE 'False' END from Employee

var monthIndex = 1;
return month = DateTimeFormatInfo.CurrentInfo.GetAbbreviatedMonthName(monthIndex);

You can try this one as well

You could add the following Maven dependency.

    <dependency>
        <groupId>org.apache.httpcomponents</groupId>
        <artifactId>httpclient</artifactId>
        <version>4.5.1</version>
    </dependency>
    <!-- https://mvnrepository.com/artifact/org.apache.httpcomponents/httpmime -->

        <groupId>org.apache.httpcomponents</groupId>
        <artifactId>httpmime</artifactId>
        <version>4.5.1</version>
    </dependency>

You could use following import in your java code.

import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpGett;
import org.apache.http.impl.client.HttpClientBuilder;
import org.apache.http.client.methods.HttpUriRequest;

You could use following code block in your java code.

HttpClient client = HttpClientBuilder.create().build();
HttpUriRequest httpUriRequest = new HttpGet("http://example.domain/someuri");

HttpResponse response = client.execute(httpUriRequest);
System.out.println("Response:"+response);

I think the bulletproof way is:

if (typeof $.cookie('token') === 'undefined'){
 //no cookie
} else {
 //have cookie
}

Checking the type of a null, empty or undefined var always returns 'undefined'

Edit: You can get there even easier:

if (!!$.cookie('token')) {
 // have cookie
} else {
 // no cookie
}

!! will turn the falsy values to false. Bear in mind that this will turn 0 to false!

Per this other post: Insert all values of a..., you can do the following:

INSERT INTO new_table (Foo, Bar, Fizz, Buzz)
SELECT Foo, Bar, Fizz, Buzz
FROM initial_table

It's important to specify the column names as indicated by the other answers.

The problem, as the Traceback says, comes from the line x[i+1] = x[i] + ( t[i+1] - t[i] ) * f( x[i], t[i] ). Let's replace it in its context:

• x is an array equal to [x0 * n], so its length is 1
• you're iterating from 0 to n-2 (n doesn't matter here), and i is the index. In the beginning, everything is ok (here there's no beginning apparently... :( ), but as soon as i + 1 >= len(x) <=> i >= 0, the element x[i+1] doesn't exist. Here, this element doesn't exist since the beginning of the for loop.

To solve this, you must replace x[i+1] = x[i] + ( t[i+1] - t[i] ) * f( x[i], t[i] ) by x.append(x[i] + ( t[i+1] - t[i] ) * f( x[i], t[i] )).

You can iterate over the index values if your dataframe has already been created.

df = df.groupby('l_customer_id_i').agg(lambda x: ','.join(x))
for name in df.index:
    print name
    print df.loc[name]

Simple PowerShell commands to set this in the registry;

New-PSDrive -Name HKCR -PSProvider Registry -Root HKEY_CLASSES_ROOT
Set-ItemProperty -Path "HKCR:\Microsoft.PowerShellScript.1\Shell\open\command" -name '(Default)' -Value '"C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe" -noLogo -ExecutionPolicy unrestricted -file "%1"'

An easy approach would be making all the blank cells NA and only keeping complete cases. You might also look for na.omit examples. It is a widely discussed topic.

df[df==""]<-NA
df<-df[complete.cases(df),]

issue the command:

SET time_zone = 'America/New_York';

(Or whatever time zone GMT+1 is.: http://www.php.net/manual/en/timezones.php)

This is the command to set the MySQL timezone for an individual client, assuming that your clients are spread accross multiple time zones.

This command should be executed before every SQL command involving dates. If your queries go thru a class, then this is easy to implement.

I'm late to the party but I encountered the same thing when I tried to get fancy and move my library and then had files being saved to a folder that was outdated:

.libloc <<- "C:/Program Files/rest_of_your_Library_FileName"

One other point to mention is that for Windows Computers, if you copy the address from Windows Explorer, you have to manually change the '\' to a '/' for the directory to be recognized.

VB is 0-indexed in array declarations, so seomthing like Dim myArray(10) as String gives you 11 elements. It's a common mistake when translating from C languages.

So, for an empty array, either of the following would work:

Dim str(-1) as String ' -1 + 1 = 0, so this has 0 elements
Dim str() as String = New String() { } ' implicit size, initialized to empty

You need the following tags to get a WhatsApp image preview:

<meta property="og:type" content="website" />
<meta property="og:url" content="https://url.com/" />
<meta property="og:description" content="Website description" />
<meta property="og:image" content="image.png" />
<meta property="og:image:width" content="600" />
<meta property="og:image:height" content="600" />

As Facebook docs says, if you specify the og:image size it will be fetched fastly instead of asynchronously otherwise.

PNG is recommended for image format. 600x600 pixels at least is recommended.

Here is the same thing from a Jupyter screenshot:

nvm install 0.5.0 #install previous version of choice

nvm alias default 0.5.0 #set it to default

nvm use default #use the new default as active version globally.

Without the last, the active version doesn't change to the new default. So, when you open a new terminal or restart server, the old default version remains active.

Also you can use ui-sref-active directive:

<ul>
  <li ui-sref-active="active" class="item">
    <a href ui-sref="app.user({user: 'bilbobaggins'})">@bilbobaggins</a>
  </li>
  <!-- ... -->
</ul>

Or filters: "stateName" | isState & "stateName" | includedByState

You can use map function also.

someArray = [{name:"Kristian", lines:"2,5,10"},{name:"John",lines:"1,19,26,96"}];
newArray=[];
someArray.map(function(obj, index){
    if(obj.name !== "Kristian"){
       newArray.push(obj);
    }
});
someArray = newArray;
console.log(someArray);

I assume we are discussing division of integers.

Consider that I got two number 1502 and 30, and I wanted to calculate 1502/30. This is how we do this:

First we align 30 with 1501 at its most significant figure; 30 becomes 3000. And compare 1501 with 3000, 1501 contains 0 of 3000. Then we compare 1501 with 300, it contains 5 of 300, then compare (1501-5*300) with 30. At so at last we got 5*(10^1) = 50 as the result of this division.

Now convert both 1501 and 30 into binary digits. Then instead of multiplying 30 with (10^x) to align it with 1501, we multiplying (30) in 2 base with 2^n to align. And 2^n can be converted into left shift n positions.

Here is the code:

int divide(int a, int b){
    if (b != 0)
        return;

    //To check if a or b are negative.
    bool neg = false;
    if ((a>0 && b<0)||(a<0 && b>0))
        neg = true;

    //Convert to positive
    unsigned int new_a = (a < 0) ? -a : a;
    unsigned int new_b = (b < 0) ? -b : b;

    //Check the largest n such that b >= 2^n, and assign the n to n_pwr
    int n_pwr = 0;
    for (int i = 0; i < 32; i++)
    {
        if (((1 << i) & new_b) != 0)
            n_pwr = i;
    }

    //So that 'a' could only contain 2^(31-n_pwr) many b's,
    //start from here to try the result
    unsigned int res = 0;
    for (int i = 31 - n_pwr; i >= 0; i--){
        if ((new_b << i) <= new_a){
            res += (1 << i);
            new_a -= (new_b << i);
        }
    }

    return neg ? -res : res;
}

Didn't test it, but you get the idea.

To Nihat's point (above): Evan You has advised against using _uid: "The vm _uid is reserved for internal use and it's important to keep it private (and not rely on it in user code) so that we keep the flexibility to change its behavior for potential future use cases. ... I'd suggest generating UIDs yourself [using a module, a global mixin, etc.]"

Using the suggested mixin in this GitHub issue to generate the UID seems like a better approach:

let uuid = 0;

export default {
  beforeCreate() {
    this.uuid = uuid.toString();
    uuid += 1;
  },
};

const int* ptr; here think like *ptr is constant and *ptr can't be change again

EDIT (2019-02-03) Note that the following answer only works on older versions of Python. More recently, OrderedDict has been rewritten in C. In addition this does touch double-underscore attributes which is frowned upon.

I just wrote a subclass of OrderedDict in a project of mine for a similar purpose. Here's the gist.

Insertion operations are also constant time O(1) (they don't require you to rebuild the data structure), unlike most of these solutions.

>>> d1 = ListDict([('a', '1'), ('b', '2')])
>>> d1.insert_before('a', ('c', 3))
>>> d1
ListDict([('c', 3), ('a', '1'), ('b', '2')])

Edit: I just found out about std::to_string which is identical in operation to my own function below. It was introduced in C++11 and is available in recent versions of gcc, at least as early as 4.5 if you enable the c++0x extensions.

std::string itos(int n)
{
   const int max_size = std::numeric_limits<int>::digits10 + 1 /*sign*/ + 1 /*0-terminator*/;
   char buffer[max_size] = {0};
   sprintf(buffer, "%d", n);
   return std::string(buffer);
}

Ordinarily it would be safer to use snprintf instead of sprintf but the buffer is carefully sized to be immune to overrun.

See an example: http://ideone.com/mKmZVE

You might want to use TRUNC function on your column when comparing with string format, so it compares only till seconds, not milliseconds.

SELECT * FROM <table_name> WHERE id = 1 
AND TRUNC(usagetime, 'SS') = '2012-09-03 08:03:06';

If you wanted to truncate upto minutes, hours, etc. that is also possible, just use appropriate notation instead of 'SS':

hour ('HH'), minute('MI'), year('YEAR' or 'YYYY'), month('MONTH' or 'MM'), Day ('DD')

Alternatively, you can use requests.Session and observe cookies before and after a request:

>>> import requests
>>> session = requests.Session()
>>> print(session.cookies.get_dict())

You can forget about using JavaScript because the browser controls whether or not it opens in a new tab. Your best option is to do something like the following instead:

<form action="http://www.yoursite.com/dosomething" method="get" target="_blank">
    <input name="dynamicParam1" type="text"/>
    <input name="dynamicParam2" type="text" />
    <input type="submit" value="submit" />
</form>

This will always open in a new tab regardless of which browser a client uses due to the target="_blank" attribute.

If all you need is to redirect with no dynamic parameters you can use a link with the target="_blank" attribute as Tim Büthe suggests.

\b <= this is a word boundary.

Matches at a position that is followed by a word character but not preceded by a word character, or that is preceded by a word character but not followed by a word character.

\w <= stands for "word character". 

It always matches the ASCII characters [A-Za-z0-9_]

Is there anything specific you are trying to match?

Some useful regex websites for beginners or just to wet your appetite.

• http://www.regular-expressions.info
• http://www.javascriptkit.com/javatutors/redev2.shtml
• http://www.virtuosimedia.com/dev/php/37-tested-php-perl-and-javascript-regular-expressions
• http://www.i-programmer.info/programming/javascript/4862-master-javascript-regular-expressions.html

I found this to be a very useful book:

• Mastering Regular Expressions by Jeffrey E.F. Friedl

Pandas is based on NumPy arrays. The key to speed with NumPy arrays is to perform your operations on the whole array at once, never row-by-row or item-by-item.

For example, if close is a 1-d array, and you want the day-over-day percent change,

pct_change = close[1:]/close[:-1]

This computes the entire array of percent changes as one statement, instead of

pct_change = []
for row in close:
    pct_change.append(...)

So try to avoid the Python loop for i, row in enumerate(...) entirely, and think about how to perform your calculations with operations on the entire array (or dataframe) as a whole, rather than row-by-row.

PK - Primary Key

NN - Not Null

BIN - Binary (stores data as binary strings. There is no character set so sorting and comparison is based on the numeric values of the bytes in the values.)

UN - Unsigned (non-negative numbers only. so if the range is -500 to 500, instead its 0 - 1000, the range is the same but it starts at 0)

UQ - Create/remove Unique Key

ZF - Zero-Filled (if the length is 5 like INT(5) then every field is filled with 0’s to the 5th digit. 12 = 00012, 400 = 00400, etc. )

AI - Auto Increment

G - Generated column. i.e. value generated by a formula based on the other columns

If still all the above doen't work you can always add to the script

    set "JAVA_OPTS=-Xdebug -Xrunjdwp:transport=dt_socket,address=8000,server=y,suspend=n"

\begin{tikzpicture}
    \tikzstyle{every node}=[font=\fontsize{30}{30}\selectfont]
\end{tikzpicture}

You may be interested in the csv module, which is designed for comma-separated files but can be easily modified to use a custom delimiter.

import csv
csv.register_dialect( "myDialect", delimiter = "__", <other-options> )
lines = [ "MATCHES__STRING" ]

for row in csv.reader( lines ):
    ...

var rotator = function(){
  widget.Rotator.rotate();
  setTimeout(rotator,5000);
};
rotator();

Or:

setInterval(
  function(){ widget.Rotator.rotate() },
  5000
);

Or:

setInterval(
  widget.Rotator.rotate.bind(widget.Rotator),
  5000
);

I use the AbsoluteUri and you can get it like this:

string myURI = Request.Url.AbsoluteUri;
 if (!WebSecurity.IsAuthenticated) {
        Response.Redirect("~/Login?returnUrl="
            + Request.Url.AbsoluteUri );

Then after you login:

var returnUrl = Request.QueryString["returnUrl"];
 if(WebSecurity.Login(username,password,true)){
                Context.RedirectLocal(returnUrl);

It works well for me.

In my case I had special instruction into nginx configuration file:

location ~ \.(js|css|png|jpg|gif|swf|ico|pdf|mov|fla|zip|rar)$ {
            try_files $uri =404;
    }

All clients have received '404' because nginx nothing known about Flask.

I hope it help someone.

Try configuring the project structure as given below:

Put all the repo, service, packages in the child package of the main package:

package com.leisure.moviemax;  //Parent package
        
@SpringBootApplication
@PropertySource(value={"classpath:conf.properties"})
    
public class MoviemaxApplication implements CommandLineRunner {
        
package com.leisure.moviemax.repo; //child package

@Repository
public interface UsrRepository extends JpaRepository<UserEntity,String> {

<script type="text/javascript">
function Check() {
    if (document.getElementById('yesCheck').checked) {
        document.getElementById('ifYes').style.display = 'block';
    } 
    else {
        document.getElementById('ifYes').style.display = 'none';

   }
}

</script>
</head>
<body>
Select os :
<br>
Two
<input type="radio" onclick="Check();" value="Two" name="categor`enter code here`y" id="yesCheck"/>One
<input type="radio" onclick="Check();" value="One"name="category"/>
<br>
<div id="ifYes" style="display:none" >
Three<input type="radio" name="win" value="Three"/>
Four<input type="radio" name="win" value="Four"/>

Match objects are always true, and None is returned if there is no match. Just test for trueness.

Code:

>>> st = 'bar'
>>> m = re.match(r"ba[r|z|d]",st)
>>> if m:
...     m.group(0)
...
'bar'

Output = bar

If you want search functionality

>>> st = "bar"
>>> m = re.search(r"ba[r|z|d]",st)
>>> if m is not None:
...     m.group(0)
...
'bar'

and if regexp not found than

>>> st = "hello"
>>> m = re.search(r"ba[r|z|d]",st)
>>> if m:
...     m.group(0)
... else:
...   print "no match"
...
no match

As @bukzor mentioned if st = foo bar than match will not work. So, its more appropriate to use re.search.

1. Implement a slot in your QMainWindow where you will open your new Window,
2. Place a widget on your QMainWindow,
3. Connect a signal from this widget to a slot from the QMainWindow (for example: if the widget is a QPushButton connect the signal click() to the QMainWindow custom slot you have created).

Code example:

MainWindow.h

// ...
include "newwindow.h"
// ...
public slots:
   void openNewWindow();
// ...
private:
   NewWindow *mMyNewWindow;
// ...
}

MainWindow.cpp

// ...
   MainWindow::MainWindow()
   {
      // ...
      connect(mMyButton, SIGNAL(click()), this, SLOT(openNewWindow()));
      // ...
   }
// ...
void MainWindow::openNewWindow()
{
   mMyNewWindow = new NewWindow(); // Be sure to destroy your window somewhere
   mMyNewWindow->show();
   // ...
}

This is an example on how display a custom new window. There are a lot of ways to do this.

if you are newly implementing recaptcha on your site, I would suggest adding api.js and let google collect behavioral data of your users 1-2 days. It is much fail-safe this way, especially before starting to use score.

public void myfunction(){
        try
        {
            sqlcon.Open();
            SqlCommand cmd = new SqlCommand("sp_laba", sqlcon);
            cmd.CommandType = CommandType.StoredProcedure;
            cmd.ExecuteNonQuery();
        }
        catch(Exception ex)
        {
            MessageBox.Show(ex.Message);
        }
        finally
        {
            sqlcon.Close();
        }
}

Use org.hibernate.annotations for doing Cascade , if the hibernate and JPA are used together , its somehow complaining on saving the child objects.

For those having problems comparing object properties, inside the helper add this solution

Ember.js helper not properly recognizing a parameter

I met the same problem. I found the solution in the solution from kb.vmware.com.
It works for me by adding

usb.quirks.device0 = "0xvid:0xpid skip-refresh"

Detail as below:

1. Shut down the virtual machine and quit Workstation/Fusion.
   
   Caution: Do not skip this step.
    
2. Open the vmware.log file within the virtual machine bundle. For more information, see Locating a virtual machine bundle in VMware Workstation/Fusion (1007599).
3. In the Filter box at the top of the Console window, enter the name of the device manufacturer.
   
   For example, if you enter the name Apple, you see a line that looks similar to:
   
   

   vmx | USB: Found device [name:Apple\ IR\ Receiver vid:05ac pid:8240 path:13/7/2 speed:full family:hid]

   
   
   The line has the name of the USB device and its vid and pid information. Make a note of the vid and pid values.
    

4. Open the .vmx file using a text editor. For more information, see Editing the .vmx file for your Workstation/Fusion virtual machine (1014782).
5. Add this line to the .vmx file, replacing vid and pid with the values noted in Step 2, each prefixed by the number 0 and the letter x .
   
   

   usb.quirks.device0 = "0xvid:0xpid skip-reset"
   
   

   For example, for the Apple device found in step 2, this line is:
   
   

   usb.quirks.device0 = "0x05ac:0x8240 skip-reset"
    

6. Save the .vmx file.
7. Re-open Workstation/Fusion. The edited .vmx file is reloaded with the changes.
8. Start the virtual machine, and connect the device.
9. If the issue is not resolved, replace the quirks line added in Step 4 with one of these lines, in the order provided, and repeat Steps 5 to 8:

usb.quirks.device0 = "0xvid:0xpid skip-refresh"
usb.quirks.device0 = "0xvid:0xpid skip-setconfig"
usb.quirks.device0 = "0xvid:0xpid skip-reset, skip-refresh, skip-setconfig"

Notes:

• Use one of these lines at a time. If one does not work, replace it with another one in the list. Do not add more than one of these in the .vmx file at a time.
• The last line uses all three quirks in combination. Use this only if the other three lines do not work.

Refer this to see in detail.

In the header file define a base class:

class BaseClass {
public:
    BaseClass(params);
};

Then define a derived class as inheriting the BaseClass:

class DerivedClass : public BaseClass {
public:
    DerivedClass(params);
};

In the source file define the BaseClass constructor:

BaseClass::BaseClass(params)
{
     //Perform BaseClass initialization
}

By default the derived constructor only calls the default base constructor with no parameters; so in this example, the base class constructor is NOT called automatically when the derived constructor is called, but it can be achieved simply by adding the base class constructor syntax after a colon (:). Define a derived constructor that automatically calls its base constructor:

DerivedClass::DerivedClass(params) : BaseClass(params)
{
     //This occurs AFTER BaseClass(params) is called first and can
     //perform additional initialization for the derived class
}

The BaseClass constructor is called BEFORE the DerivedClass constructor, and the same/different parameters params may be forwarded to the base class if desired. This can be nested for deeper derived classes. The derived constructor must call EXACTLY ONE base constructor. The destructors are AUTOMATICALLY called in the REVERSE order that the constructors were called.

EDIT: There is an exception to this rule if you are inheriting from any virtual classes, typically to achieve multiple inheritance or diamond inheritance. Then you MUST explicitly call the base constructors of all virtual base classes and pass the parameters explicitly, otherwise it will only call their default constructors without any parameters. See: virtual inheritance - skipping constructors

Here is complete console working application code. Please install RestSharp package.

The shortest way! it's working for me, Where NA is my default value.

<td th:text="${ins.eValue!=null}? ${ins.eValue}:'NA'" />

1. Check the .aws directory under home directory. Windows: C:\Users<home-name>.aws Linux: ~/.aws

2. Under this directory, you will find the config as well as credentials file. It will have the information from the aws configure that you may have run before. IF not, then

3. Run aws configure Enter the access key - secret key - enter secret key region - (ap-southeast-1 or us-east-1 or any other regions) format - (json or leave it blank, it will pick up default values you may simply hit enter)

4. From the Step 2, you should see the config file, open it, it should have the region. Please ensure there is region specified.

5. You may now run the following command to list the buckets aws s3 ls It should work fine.

Beside the excellent answer of KLE, we can also make something more flexible:

boolean b = string.equalsIgnoreCase("true") || string.equalsIgnoreCase("t") || 
        string.equalsIgnoreCase("yes") || string.equalsIgnoreCase("y") || 
        string.equalsIgnoreCase("sure") || string.equalsIgnoreCase("aye") || 
        string.equalsIgnoreCase("oui") || string.equalsIgnoreCase("vrai");

(inspired by zlajo's answer... :-))

@robert-hurst has a cleaner approach.

However, this solution may also be used, in places when you actually want to have a copy of Data Url after copying. For example, when you are building a website that uses lots of image/canvas operations.

    // select canvas elements
    var sourceCanvas = document.getElementById("some-unique-id");
    var destCanvas = document.getElementsByClassName("some-class-selector")[0];

    //copy canvas by DataUrl
    var sourceImageData = sourceCanvas.toDataURL("image/png");
    var destCanvasContext = destCanvas.getContext('2d');

    var destinationImage = new Image;
    destinationImage.onload = function(){
      destCanvasContext.drawImage(destinationImage,0,0);
    };
    destinationImage.src = sourceImageData;

assuming you have a SQL table called mydata - you can load data from a csv file as follows:

COPY MYDATA FROM '<PATH>/MYDATA.CSV' CSV HEADER;

For more details refer to: http://www.postgresql.org/docs/9.2/static/sql-copy.html

Java's transient keyword is used to denote that a field is not to be serialized, whereas JPA's @Transient annotation is used to indicate that a field is not to be persisted in the database, i.e. their semantics are different.

Using Java Streams you can just use an IntStream mapping the objects:

JSONArray array = new JSONArray(jsonString);
List<String> result = IntStream.range(0, array.length())
        .mapToObj(array::get)
        .map(Object::toString)
        .collect(Collectors.toList());

I found that the accepted answer worked for a fixed width, but not a fixed height. For a fixed height, it would just increase the width to fit everything on one line, unless there was a line break in the text.

The width function calls the height function multiple times, but it is a quick calculation and I didn't notice performance issues using the function in the rows of a UITable.

extension String {

    public func height(withConstrainedWidth width: CGFloat, font: UIFont) -> CGFloat {
        let constraintRect = CGSize(width: width, height: .greatestFiniteMagnitude)
        let boundingBox = self.boundingRect(with: constraintRect, options: .usesLineFragmentOrigin, attributes: [.font : font], context: nil)

        return ceil(boundingBox.height)
    }

    public func width(withConstrainedHeight height: CGFloat, font: UIFont, minimumTextWrapWidth:CGFloat) -> CGFloat {

        var textWidth:CGFloat = minimumTextWrapWidth
        let incrementWidth:CGFloat = minimumTextWrapWidth * 0.1
        var textHeight:CGFloat = self.height(withConstrainedWidth: textWidth, font: font)

        //Increase width by 10% of minimumTextWrapWidth until minimum width found that makes the text fit within the specified height
        while textHeight > height {
            textWidth += incrementWidth
            textHeight = self.height(withConstrainedWidth: textWidth, font: font)
        }
        return ceil(textWidth)
    }
}

Very basic but

• $.load(): Load a piece of html into a container DOM.
• $.get(): Use this if you want to make a GET call and play extensively with the response.
• $.post(): Use this if you want to make a POST call and don’t want to load the response to some container DOM.
• $.ajax(): Use this if you need to do something when XHR fails, or you need to specify ajax options (e.g. cache: true) on the fly.

Just an update to above answers :

If you want to have see changes in the click event, i.e. Color of your UIVIew shud change whenever user clicks the UIView then make changes as below...

class ClickableUIView: UIView {
    override func touchesBegan(touches: Set<UITouch>, withEvent event: UIEvent?) {
            if let touch = touches.first {
                let currentPoint = touch.locationInView(self)
                // do something with your currentPoint
            }

            self.backgroundColor = UIColor.magentaColor()//Color when UIView is clicked.
        }

        override func touchesMoved(touches: Set<UITouch>, withEvent event: UIEvent?) {
            if let touch = touches.first {
                let currentPoint = touch.locationInView(self)
                // do something with your currentPoint
            }

            self.backgroundColor = UIColor.magentaColor()//Color when UIView is clicked.
        }

        override func touchesEnded(touches: Set<UITouch>, withEvent event: UIEvent?) {
            if let touch = touches.first {
                let currentPoint = touch.locationInView(self)
                // do something with your currentPoint
            }

            self.backgroundColor = UIColor.whiteColor()//Color when UIView is not clicked.

}//class closes here

Also, call this Class from Storyboard & ViewController as:

@IBOutlet weak var panVerificationUIView:ClickableUIView!

Quick note: if you're also using coord_flip() to flip the x and the y axis, you won't be able to set range limits using coord_cartesian() because those two functions are exclusive (see here).

Fortunately, this is an easy fix; set your limits within coord_flip() like so:

p + coord_flip(ylim = c(3,5), xlim = c(100, 400))

This just alters the visible range (i.e. doesn't remove data points).

I would recommend a Set implementation where the use case is limit to referencing or search for existence and Tuple implementation where the use case requires you to perform iteration. A list is a low-level implementation and requires significant memory overhead.

I have no doubt on @Grant answer. But I face few issues sometimes such as if the column name is similar to any reserved keyword of postgresql such as natural in this case similar SQL is difficult to run from the command line as "\natural\" will be needed in Query field. So my approach is to write the SQL in separate file and run the SQL file from command line. This has another advantage too. If you have to change the query for a large script you do not need to touch the script file or command. Only change the SQL file like this

psql -h localhost -d database -U postgres -p 5432 -a -q -f /path/to/the/file.sql

I got a shortcut for Idle (Python GUI).

• Click on Window icon at the bottom left or use Window Key (only Python 2), you will see Idle (Python GUI) icon
• Right click on the icon then more
• Open File Location
• A new window will appears, and you will see the shortcut of Idle (Python GUI)
• Right click, hold down and pull out to desktop to create a shortcut of Python GUI on desktop.

To get it so that it can be loaded sensibly by Excel, you need to use a comma (the csv default) as the delimiter, unless you are in a locale (e.g. Europe) where you need a semicolon.

What you can do is set your default database using the sp_defaultdb system stored procedure. Log in as you have done and then click the New Query button. After that simply run the sp_defaultdb command as follows:

Exec sp_defaultdb @loginame='login', @defdb='master' 

According to this link, it solved by entering this command:

Use pd.to_numeric with errors='coerce'

# Setup
s = pd.Series(['1', '2', '3', '4', '.'])
s

0    1
1    2
2    3
3    4
4    .
dtype: object

pd.to_numeric(s, errors='coerce')

0    1.0
1    2.0
2    3.0
3    4.0
4    NaN
dtype: float64

If you need the NaNs filled in, use Series.fillna.

pd.to_numeric(s, errors='coerce').fillna(0, downcast='infer')

0    1
1    2
2    3
3    4
4    0
dtype: float64

Note, downcast='infer' will attempt to downcast floats to integers where possible. Remove the argument if you don't want that.

From v0.24+, pandas introduces a Nullable Integer type, which allows integers to coexist with NaNs. If you have integers in your column, you can use

pd.__version__
# '0.24.1'

pd.to_numeric(s, errors='coerce').astype('Int32')

0      1
1      2
2      3
3      4
4    NaN
dtype: Int32

There are other options to choose from as well, read the docs for more.

Extension for DataFrames

If you need to extend this to DataFrames, you will need to apply it to each row. You can do this using DataFrame.apply.

# Setup.
np.random.seed(0)
df = pd.DataFrame({
    'A' : np.random.choice(10, 5), 
    'C' : np.random.choice(10, 5), 
    'B' : ['1', '###', '...', 50, '234'], 
    'D' : ['23', '1', '...', '268', '$$']}
)[list('ABCD')]
df

   A    B  C    D
0  5    1  9   23
1  0  ###  3    1
2  3  ...  5  ...
3  3   50  2  268
4  7  234  4   $$

df.dtypes

A     int64
B    object
C     int64
D    object
dtype: object

df2 = df.apply(pd.to_numeric, errors='coerce')
df2

   A      B  C      D
0  5    1.0  9   23.0
1  0    NaN  3    1.0
2  3    NaN  5    NaN
3  3   50.0  2  268.0
4  7  234.0  4    NaN

df2.dtypes

A      int64
B    float64
C      int64
D    float64
dtype: object

You can also do this with DataFrame.transform; although my tests indicate this is marginally slower:

df.transform(pd.to_numeric, errors='coerce')

   A      B  C      D
0  5    1.0  9   23.0
1  0    NaN  3    1.0
2  3    NaN  5    NaN
3  3   50.0  2  268.0
4  7  234.0  4    NaN

If you have many columns (numeric; non-numeric), you can make this a little more performant by applying pd.to_numeric on the non-numeric columns only.

df.dtypes.eq(object)

A    False
B     True
C    False
D     True
dtype: bool

cols = df.columns[df.dtypes.eq(object)]
# Actually, `cols` can be any list of columns you need to convert.
cols
# Index(['B', 'D'], dtype='object')

df[cols] = df[cols].apply(pd.to_numeric, errors='coerce')
# Alternatively,
# for c in cols:
#     df[c] = pd.to_numeric(df[c], errors='coerce')

df

   A      B  C      D
0  5    1.0  9   23.0
1  0    NaN  3    1.0
2  3    NaN  5    NaN
3  3   50.0  2  268.0
4  7  234.0  4    NaN

Applying pd.to_numeric along the columns (i.e., axis=0, the default) should be slightly faster for long DataFrames.

I faced the same error and did some research to only see that there could be different scenarios to this error. Let me share my findings.

Scenario 1: There cannot be spaces beside the = (equals) sign

$ export TEMP_ENV = example-value
-bash: export: `=': not a valid identifier
// this is the answer to the question

$ export TEMP_ENV =example-value
-bash: export: `=example-value': not a valid identifier

$ export TEMP_ENV= example-value
-bash: export: `example-value': not a valid identifier

Scenario 2: Object value assignment should not have spaces besides quotes

$ export TEMP_ENV={ "key" : "json example" } 
-bash: export: `:': not a valid identifier
-bash: export: `json example': not a valid identifier
-bash: export: `}': not a valid identifier

Scenario 3: List value assignment should not have spaces between values

$ export TEMP_ENV=[1,2 ,3 ]
-bash: export: `,3': not a valid identifier
-bash: export: `]': not a valid identifier

I'm sharing these, because I was stuck for a couple of hours trying to figure out a workaround. Hopefully, it will help someone in need.

Got the same error, CHECK THIS : MINOR SILLY MISTAKE

check findviewbyid(R.id.yourID); If you have put the id correct or not.

Setting the Hadoop_Home environment variable in system properties didn't work for me. But this did:

• Set the Hadoop_Home in the Eclipse Run Configurations environment tab.
• Follow the 'Windows Environment Setup' from here

You have to switch it!

switch (true) {
    case ( (pageid === "listing-page") || (pageid === ("home-page") ):
        alert("hello");
        break;
    case (pageid === "details-page"):
        alert("goodbye");
        break;
}

First of all, if you are trying to encode apostophes for querystrings, they need to be URLEncoded, not escaped with a leading backslash. For that use URLEncoder.encode(String, String) (BTW: the second argument should always be "UTF-8"). Secondly, if you want to replace all instances of apostophe with backslash apostrophe, you must escape the backslash in your string expression with a leading backslash. Like this:

"This is' it".replace("'", "\\'");

Edit:

I see now that you are probably trying to dynamically build a SQL statement. Do not do it this way. Your code will be susceptible to SQL injection attacks. Instead use a PreparedStatement.

Use this in procedure

declare cu cursor for SELECT [name] FROM sys.Tables where [name] like 'tbl_%'
declare @table varchar(100)
declare @sql nvarchar(1000)

OPEN cu  
FETCH NEXT FROM cu INTO @table 

WHILE @@FETCH_STATUS = 0  
BEGIN  
    set @sql = N'delete from ' + @table
    EXEC sp_executesql @sql
    FETCH NEXT FROM cu INTO @table 
END   
CLOSE cu;  
DEALLOCATE cu;

If a class type is not defined, you'll get a compiler error if you try to use the class, so in that sense you should have to check.

If you have an instance, and you want to ensure it's not null, simply check for null:

if (value != null)
{
    // it's not null. 
}

No, you don't have to bother grep.

find $dir -size 0 ! -name "*.xml"

I am not sure when it was added, but I'm using v0.10.8 and Alt + Z is the keyboard shortcut for turning word wrap on and off. This satisfies the requirement of "able to turn it on and off quickly".

The setting does not persist after closing Visual Studio Code. To persist, you need to set it through Radha's answer of using the settings.json file...

// Place your settings in this file to overwrite the default settings
{ "editor.wrappingColumn": 0 }

/* Provoke an error -- the BONES table does not exist */

$sth = $dbh->prepare('SELECT skull FROM bones');

In most browsers, you need the Range and Selection objects. You specify each of the selection boundaries as a node and an offset within that node. For example, to set the caret to the fifth character of the second line of text, you'd do the following:

function setCaret() {
    var el = document.getElementById("editable")
    var range = document.createRange()
    var sel = window.getSelection()
    
    range.setStart(el.childNodes[2], 5)
    range.collapse(true)
    
    sel.removeAllRanges()
    sel.addRange(range)
}

<div id="editable" contenteditable="true">
  text text text<br>text text text<br>text text text<br>
</div>

<button id="button" onclick="setCaret()">focus</button>

IE < 9 works completely differently. If you need to support these browsers, you'll need different code.

in my case, I forget to add (or deleted accidentally) firebase core in build gradle

implementation 'com.google.firebase:firebase-core:xx.x.x'

import sys
import time

a = 0  
for x in range (0,3):  
    a = a + 1  
    b = ("Loading" + "." * a)
    # \r prints a carriage return first, so `b` is printed on top of the previous line.
    sys.stdout.write('\r'+b)
    time.sleep(0.5)
print (a)

Note that you might have to run sys.stdout.flush() right after sys.stdout.write('\r'+b) depending on which console you are doing the printing to have the results printed when requested without any buffering.

I had a similar issue and was able to resolve it by identifying which JDBC driver I intended to use. In my case, I was connecting to an Oracle database. I placed the following statement, prior to creating the connection variable.

DriverManager.registerDriver( new oracle.jdbc.driver.OracleDriver());

The three constants have similar functions nowadays, but different historical origins, and very occasionally you may be required to use one or the other.

You need to think back to the days of old manual typewriters to get the origins of this. There are two distinct actions needed to start a new line of text:

1. move the typing head back to the left. In practice in a typewriter this is done by moving the roll which carries the paper (the "carriage") all the way back to the right -- the typing head is fixed. This is a carriage return.
2. move the paper up by the width of one line. This is a line feed.

In computers, these two actions are represented by two different characters - carriage return is CR, ASCII character 13, vbCr; line feed is LF, ASCII character 10, vbLf. In the old days of teletypes and line printers, the printer needed to be sent these two characters -- traditionally in the sequence CRLF -- to start a new line, and so the CRLF combination -- vbCrLf -- became a traditional line ending sequence, in some computing environments.

The problem was, of course, that it made just as much sense to only use one character to mark the line ending, and have the terminal or printer perform both the carriage return and line feed actions automatically. And so before you knew it, we had 3 different valid line endings: LF alone (used in Unix and Macintoshes), CR alone (apparently used in older Mac OSes) and the CRLF combination (used in DOS, and hence in Windows). This in turn led to the complications of DOS / Windows programs having the option of opening files in text mode, where any CRLF pair read from the file was converted to a single CR (and vice versa when writing).

So - to cut a (much too) long story short - there are historical reasons for the existence of the three separate line separators, which are now often irrelevant: and perhaps the best course of action in .NET is to use Environment.NewLine which means someone else has decided for you which to use, and future portability issues should be reduced.

Your SVN passwords in Ubuntu (12.04) are in:

~/.subversion/auth/svn.simple/

However in newer versions they are encrypted, as earlier someone mentioned. To find gnome-keyring passwords, I suggest You to use 'gkeyring' program.

To install it on Ubuntu – add repository :

sudo add-apt-repository ppa:kampka/ppa
sudo apt-get update

Install it:

sudo apt-get install gkeyring

And run as following:

gkeyring --id 15 --output=name,secret

Try different key ids to find pair matching what you are looking for. Thanks to kampka for the soft.

First you need to create package:

com.myCompany.executabe (src > right click > new > package).

Follow these steps to move the Java files to your new package.

1. Select the Java files
2. Right click
3. Refactor
4. Move
5. Select your preferred package

Since I found that the above approved answer lacks some clarity and the op provides an incorrect solution that he/she will use. I therefore hope that the below example will help others. The solution is more or less portable as well.

/******************************************************************************

int dirExists(const char* const path)

    struct stat info;

    int statRC = stat( path, &info );
    if( statRC != 0 )
    {
        if (errno == ENOENT)  { return 0; } // something along the path does not exist
        if (errno == ENOTDIR) { return 0; } // something in path prefix is not a dir
        return -1;
    }

    return ( info.st_mode & S_IFDIR ) ? 1 : 0;

How about this?

var obj = {},
var isEmpty = !obj;
var hasContent = !!obj

The following command is needed to force git to send the credentials and authentication method to the proxy:

git config --global http.proxyAuthMethod 'basic'

Source: https://git-scm.com/docs/git-config#git-config-httpproxyAuthMethod

Method 1 for version 5.3

In laravel 5.3 don't have AuthController. to disable register route you should change in constructor of RegisterController like this:

You can change form:

public function __construct()
{

    $this->middleware('guest');

}

to:

use Illuminate\Support\Facades\Redirect;

public function __construct()
{

    Redirect::to('/')->send();

}

Note: for use Redirect don't forget to user Redirect; So user access to https://host_name/register it's redirect to "/".

Method 2 for version 5.3

When we use php artisan make:auth it's added Auth::route(); automatically. Please Override Route in /routes/web.php. You can change it's like this: * you need to comment this line: Auth::routes();

    <?php

/*
|--------------------------------------------------------------------------
| Web Routes
|--------------------------------------------------------------------------
|
| This file is where you may define all of the routes that are handled
| by your application. Just tell Laravel the URIs it should respond
| to using a Closure or controller method. Build something great!
|
*/


// Auth::routes();
Route::get('/login', 'Auth\LoginController@showLoginForm' );
Route::post('/login', 'Auth\LoginController@login');
Route::post('/logout', 'Auth\LoginController@logout');

Route::get('/home', 'HomeController@index');

Thanks! I hope it's can solve your problems.

to convert Pixels to dp use the TypedValue .

As the documentation mentioned : Container for a dynamically typed data value .

and use the applyDimension method :

public static float applyDimension (int unit, float value, DisplayMetrics metrics) 

which Converts an unpacked complex data value holding a dimension to its final floating point value like the following :

Resources resource = getResources();
float dp = TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_PX, 69, resource.getDisplayMetrics());

Hope that Helps .

Use the FormBorderStyle property of your Form:

this.FormBorderStyle = FormBorderStyle.FixedDialog;

below is an generic example

    //base class
    class A {
        
        // The virtual method
        protected virtualStuff1?():void;
    
        public Stuff2(){
            //Calling overridden child method by parent if implemented
            this.virtualStuff1 && this.virtualStuff1();
            alert("Baseclass Stuff2");
        }
    }
    
    //class B implementing virtual method
    class B extends A{
        
        // overriding virtual method
        public virtualStuff1()
        {
            alert("Class B virtualStuff1");
        }
    }
    
    //Class C not implementing virtual method
    class C extends A{
     
    }
    
    var b1 = new B();
    var c1= new C();
    b1.Stuff2();
    b1.virtualStuff1();
    c1.Stuff2();

Yes, I was late, but I can add for Assemble users: you can use buil-in "parseJSON" helper http://assemble.io/helpers/helpers-data.html. (Discovered in https://github.com/assemble/assemble/issues/416).

a minimal bash loop you can build off of (based off ghostdog74 answer)

for dir in directory/*                                                     
do                                                                                 
  echo ${dir}                                                                  
done

to zip a whole bunch of files by directory

for dir in directory/*
do
  zip -r ${dir##*/} ${dir}
done                                               

Why not create a viewmodel with a simple string parameter and then pass that to the view? It has the benefit of being extensible (i.e. you can then add any other things you may want to set in your controller) and it's fairly simple.

public class MyViewModel
{
    public string YourString { get; set; }
}

In the view

@model MyViewModel
@Html.Label(model => model.YourString)

In the controller

public ActionResult Index() 
{
     myViewModel = new MyViewModel();
     myViewModel.YourString = "However you are setting this."
     return View(myViewModel)
}

The better and correct solution is to have a directive. The scope is the same, whether in the controller of the directive or the main controller. Use $element to do DOM operations. The method defined in the directive controller is accessible in the main controller.

Example, finding a child element:

var app = angular.module('myapp', []);
app.directive("testDir", function () {
    function link(scope, element) { 

    }
    return {
        restrict: "AE", 
        link: link, 
        controller:function($scope,$element){
            $scope.name2 = 'this is second name';
            var barGridSection = $element.find('#barGridSection'); //helps to find the child element.
    }
    };
})

app.controller('mainController', function ($scope) {
$scope.name='this is first name'
});
