More compact way to get the difference between two datetime objects and then convert the difference into seconds is shown below (Python 3x):

from datetime import datetime
        
time1 = datetime.strftime('18 01 2021', '%d %m %Y')
    
time2 = datetime.strftime('19 01 2021', '%d %m %Y')

difference = time2 - time1

difference_in_seconds = difference.total_seconds()

onreadystatechange Stores a function (or the name of a function) to be called automatically each time the readyState property changes readyState Holds the status of the XMLHttpRequest. Changes from 0 to 4:

0: request not initialized

1: server connection established

2: request received

3: processing request

4: request finished and response is ready

status 200: "OK"

404: Page not found

Recursion is a method that call itself. In this case it is a recursion. However it will be overloading until you put a restriction inside the method to stop the loop (if-condition).

Here's another solution using a single document for the current version and all old versions:

{
    _id: ObjectId("..."),
    data: [
        { vid: 1, content: "foo" },
        { vid: 2, content: "bar" }
    ]
}

data contains all versions. The data array is ordered, new versions will only get $pushed to the end of the array. data.vid is the version id, which is an incrementing number.

Get the most recent version:

find(
    { "_id":ObjectId("...") },
    { "data":{ $slice:-1 } }
)

Get a specific version by vid:

find(
    { "_id":ObjectId("...") },
    { "data":{ $elemMatch:{ "vid":1 } } }
)

Return only specified fields:

find(
    { "_id":ObjectId("...") },
    { "data":{ $elemMatch:{ "vid":1 } }, "data.content":1 }
)

Insert new version: (and prevent concurrent insert/update)

update(
    {
        "_id":ObjectId("..."),
        $and:[
            { "data.vid":{ $not:{ $gt:2 } } },
            { "data.vid":2 }
        ]
    },
    { $push:{ "data":{ "vid":3, "content":"baz" } } }
)

2 is the vid of the current most recent version and 3 is the new version getting inserted. Because you need the most recent version's vid, it's easy to do get the next version's vid: nextVID = oldVID + 1.

The $and condition will ensure, that 2 is the latest vid.

This way there's no need for a unique index, but the application logic has to take care of incrementing the vid on insert.

Remove a specific version:

update(
    { "_id":ObjectId("...") },
    { $pull:{ "data":{ "vid":2 } } }
)

That's it!

(remember the 16MB per document limit)

You can call any language from java using Java Native Interface

<script src="http://code.jquery.com/jquery-1.9.1.js"></script>
<script type="text/javascript" >
  $(function () {
    $(".submit").click(function (event) {
      var time = $("#time").val();
      var date = $("#date").val();
      var dataString = 'time=' + time + '&date=' + date;
      console.log(dataString);
      if (time == '' || date == '')
      {
        $('.success').fadeOut(200).hide();
        $('.error').fadeOut(200).show();
      } else
      {
        $.ajax({
          type: "POST",
          url: "post.php",
          data: dataString,
          success: function (data) {
            $('.success').fadeIn(200).show();
            $('.error').fadeOut(200).hide();
            $("#data").html(data);
          }
        });
      }
      event.preventDefault();
    });
  });
</script>
<form action="post.php" method="POST">
  <input id="time" value=""><br>
  <input id="date" value=""><br>
  <input name="submit" type="button" value="Submit" class="submit">
</form>
<div id="data"></div>
<span class="error" style="display:none"> Please Enter Valid Data</span>
<span class="success" style="display:none"> Form Submitted Success</span>

<?php

print_r($_POST);
if ($_POST['date']) {
  $date = $_POST['date'];
  $time = $_POST['time'];
  echo '<h1>' . $date . '---' . $time . '</h1>';
}
else {

}
?>

There is a better solution now: Vertical align anything with just 3 lines of CSS

you can use a string formatter to pad any integer with zeros. It acts just like C's printf.

>>> d = datetime.date.today()
>>> '%02d' % d.month
'03'

Updated for py36: Use f-strings! For general ints you can use the d formatter and explicitly tell it to pad with zeros:

 >>> d = datetime.date.today()
 >>> f"{d.month:02d}"
 '07'

But datetimes are special and come with special formatters that are already zero padded:

 >>> f"{d:%d}"  # the day
 '01'
 >>> f"{d:%m}"  # the month
 '07'

Gensim implements a model called Doc2Vec for paragraph embedding.

There are different tutorials presented as IPython notebooks:

• Doc2Vec Tutorial on the Lee Dataset
• Gensim Doc2Vec Tutorial on the IMDB Sentiment Dataset
• Doc2Vec to wikipedia articles

Another method would rely on Word2Vec and Word Mover's Distance (WMD), as shown in this tutorial:

• Finding similar documents with Word2Vec and WMD

An alternative solution would be to rely on average vectors:

from gensim.models import KeyedVectors
from gensim.utils import simple_preprocess    

def tidy_sentence(sentence, vocabulary):
    return [word for word in simple_preprocess(sentence) if word in vocabulary]    

def compute_sentence_similarity(sentence_1, sentence_2, model_wv):
    vocabulary = set(model_wv.index2word)    
    tokens_1 = tidy_sentence(sentence_1, vocabulary)    
    tokens_2 = tidy_sentence(sentence_2, vocabulary)    
    return model_wv.n_similarity(tokens_1, tokens_2)

wv = KeyedVectors.load('model.wv', mmap='r')
sim = compute_sentence_similarity('this is a sentence', 'this is also a sentence', wv)
print(sim)

Finally, if you can run Tensorflow, you may try: https://tfhub.dev/google/universal-sentence-encoder/2

this better:

data: [$(this).serialize(),$.param({NonFormValue: NonFormValue})].join('&')

1- Add a view to the content view of your cell.
2- Right click your cell.
3- Make the added view as "selectedBackgroundView"

I just want to add that there is a master list of IntelliJ suppress parameters at: https://gist.github.com/vegaasen/157fbc6dce8545b7f12c

Javascript hack which is working on iOS 7. This is based on @dlo 's answer but mouseover and mouseout events are replaced by touchstart and touchend events. Basicly this script add a half second timeout before the zoom would enabled again to prevent zooming.

$("input[type=text], textarea").on({ 'touchstart' : function() {
    zoomDisable();
}});
$("input[type=text], textarea").on({ 'touchend' : function() {
    setTimeout(zoomEnable, 500);
}});

function zoomDisable(){
  $('head meta[name=viewport]').remove();
  $('head').prepend('<meta name="viewport" content="width=device-width, initial-scale=1.0, user-scalable=0" />');
}
function zoomEnable(){
  $('head meta[name=viewport]').remove();
  $('head').prepend('<meta name="viewport" content="width=device-width, initial-scale=1.0, user-scalable=1" />');
} 

This code block is enough. Please don't forget to set delegate in viewDidLoad or by storyboard just before to use the following extension:

extension YOUR_VIEW_CONTROLLER: UITextViewDelegate {

func textViewDidBeginEditing (_ textView: UITextView) {
    if YOUR_TEXT_VIEW.text.isEmpty || YOUR_TEXT_VIEW.text == "YOUR DEFAULT PLACEHOLDER TEXT HERE" {
        YOUR_TEXT_VIEW.text = nil
        YOUR_TEXT_VIEW.textColor = .red // YOUR PREFERED COLOR HERE
    }
}
func textViewDidEndEditing (_ textView: UITextView) {
    if YOUR_TEXT_VIEW.text.isEmpty {
        YOUR_TEXT_VIEW.textColor = UIColor.gray // YOUR PREFERED PLACEHOLDER COLOR HERE
        YOUR_TEXT_VIEW.text =  "YOUR DEFAULT PLACEHOLDER TEXT HERE"
    }
}

}

mp3 files sometimes throw strange mime types as per this answer: https://stackoverflow.com/a/2755288/14482130

If you are doing some user validation do not allow 'application/octet-stream' or 'application/x-zip-compressed' as suggested above since they can contain be .exe or other potentially dangerous files.

In order to validate when mime type gives a false negative you can use fleep as per this answer https://stackoverflow.com/a/52570299/14482130 to finish the validation.

Using flexbox

   #parent_div_1{
     display:flex;
     flex-wrap: wrap;
  }

This happened to me because Xcode didn't appear to like me using the same variable name in two different classes (that conform to the same protocol, if that matters, although the variable name has nothing related in any protocol). I simply renamed my new variable.

I had to step into the setters where it was crashing in order to see it, while debugging. This answer applies to iOS

Use the following code

DELIMITER $$

    CREATE TRIGGER bu_table1_each BEFORE UPDATE ON table1 FOR EACH ROW
    BEGIN
      SET new.datefield = NOW();
    END $$

    DELIMITER ;

I found that this happens because: http://support.microsoft.com/kb/913399

SQL Server only releases all the pages that a heap table uses when the following conditions are true: A deletion on this table occurs. A table-level lock is being held. Note A heap table is any table that is not associated with a clustered index.

If pages are not deallocated, other objects in the database cannot reuse the pages.

However, when you enable a row versioning-based isolation level in a SQL Server 2005 database, pages cannot be released even if a table-level lock is being held.

Microsoft's solution: http://support.microsoft.com/kb/913399

To work around this problem, use one of the following methods: Include a TABLOCK hint in the DELETE statement if a row versioning-based isolation level is not enabled. For example, use a statement that is similar to the following:

DELETE FROM TableName WITH (TABLOCK)

Note represents the name of the table. Use the TRUNCATE TABLE statement if you want to delete all the records in the table. For example, use a statement that is similar to the following:

TRUNCATE TABLE TableName

Create a clustered index on a column of the table. For more information about how to create a clustered index on a table, see the "Creating a Clustered Index" topic in SQL

You'll notice at the bottom of the link that it is NOT noted that it applies to SQL Server 2008 but I think it does

You could try:

.modal.modal-wide .modal-dialog {
  width: 90%;
}

.modal-wide .modal-body {
  overflow-y: auto;
}

Just add .modal-wide to your classes

Today, I mistakenly checked out on a commit and started working on it, making some commits on a detach HEAD state. Then I pushed to the remote branch using the following command:

git push origin HEAD: <My-remote-branch>

Then

git checkout <My-remote-branch>

Then

git pull

I finally got my all changes in my branch that I made in detach HEAD.

What is the need of static method in interface, static methods are used basically when you don't have to create an instance of object whole idea of interface is to bring in OOP concepts with introduction of static method you're diverting from concept.

Once I had to make the same decision and I'm really happy with that decision today. Use resque scheduler because not only a seperate redis will take out the load from your db, you will also have access to many plugins like resque-web which provides a great user interface. As your system develops you will have more and more tasks to schedule so you will be able to control them from a single place.

I had also similar problem. In my case brokerUrl was not configured properly. So that's way I received following Error:

Cause: Error While attempting to add new Connection to the pool: nested exception is javax.jms.JMSException: Could not connect to broker URL : tcp://localhost:61616. Reason: java.net.ConnectException: Connection refused

& I resolved it following way.

   ActiveMQConnectionFactory connectionFactory = new ActiveMQConnectionFactory();

  connectionFactory.setBrokerURL("tcp://hostname:61616");
  connectionFactory.setUserName("admin");
  connectionFactory.setPassword("admin");

You can get all keys / values and preserve the hierarchy with this

// get keys of an object or array
function getkeys(z){
  var out=[]; 
  for(var i in z){out.push(i)};
  return out;
}

// print all inside an object
function allInternalObjs(data, name) {
  name = name || 'data';
  return getkeys(data).reduce(function(olist, k){
    var v = data[k];
    if(typeof v === 'object') { olist.push.apply(olist, allInternalObjs(v, name + '.' + k)); }
    else { olist.push(name + '.' + k + ' = ' + v); }
    return olist;
  }, []);
}

// run with this
allInternalObjs({'a':[{'b':'c'},{'d':{'e':5}}],'f':{'g':'h'}}, 'ob')

This is a modification on (https://stackoverflow.com/a/25063574/1484447)

If you are invoking share Intent in Cordova plugin, setting the Flag will not help. Instead use this -

cordova.getActivity().startActivity(Intent.createChooser(shareIntent, "title"));

In javascript there are no block-level scopes only function-level scopes:

Read this article about javaScript Scoping and Hoisting.

See how I debugged your code:

var deferred = $q.defer();
deferred.count = i;

console.log(deferred.count); // 0,1,2,3,4,5 --< all deferred objects

// some code

.success(function(data){
   console.log(deferred.count); // 5,5,5,5,5,5 --< only the last deferred object
   deferred.resolve(data);
})

• When you write var deferred= $q.defer(); inside a for loop it's hoisted to the top of the function, it means that javascript declares this variable on the function scope outside of the for loop.
• With each loop, the last deferred is overriding the previous one, there is no block-level scope to save a reference to that object.
• When asynchronous callbacks (success / error) are invoked, they reference only the last deferred object and only it gets resolved, so $q.all is never resolved because it still waits for other deferred objects.
• What you need is to create an anonymous function for each item you iterate.
• Since functions do have scopes, the reference to the deferred objects are preserved in a closure scope even after functions are executed.
• As #dfsq commented: There is no need to manually construct a new deferred object since $http itself returns a promise.

Solution with angular.forEach:

Here is a demo plunker: http://plnkr.co/edit/NGMp4ycmaCqVOmgohN53?p=preview

UploadService.uploadQuestion = function(questions){

    var promises = [];

    angular.forEach(questions , function(question) {

        var promise = $http({
            url   : 'upload/question',
            method: 'POST',
            data  : question
        });

        promises.push(promise);

    });

    return $q.all(promises);
}

My favorite way is to use Array#map:

Here is a demo plunker: http://plnkr.co/edit/KYeTWUyxJR4mlU77svw9?p=preview

UploadService.uploadQuestion = function(questions){

    var promises = questions.map(function(question) {

        return $http({
            url   : 'upload/question',
            method: 'POST',
            data  : question
        });

    });

    return $q.all(promises);
}

here's the best of both worlds.

I also "like" underscores, besides all your positive points about them, there is also a certain old-school style to them.

So what I do is use underscores and simply add a small rewrite rule to your Apache's .htaccess file to re-write all underscores to hyphens.

I searched for help on this topic as I came across the same issue.

Although the following may not be the Answer to the question asked originally in 2012 it may be a solution for those who come across this thread.

A way to solve this is to check where your project is within the solution. It turns out for my instance (I was trying to install a NuGet package but it wouldn't and the listed error came up) that my project file was not included within the solution directory although showing in the solution explorer. I deleted the project from the directory out of scope and re-added the project but this time within the correct location.

You can try this

Dim occurCount As Integer = Len(testStr) - Len(testStr.Replace(testCharStr, ""))

my two cents about logic:

syntax is "old date" - :"new date", so:

tf.contrib has moved out of TF starting TF 2.0 alpha.
Take a look at these tf 2.0 release notes https://github.com/tensorflow/tensorflow/releases/tag/v2.0.0-alpha0
You can upgrade your TF 1.x code to TF 2.x using the tf_upgrade_v2 script https://www.tensorflow.org/alpha/guide/upgrade

Of course it's approximate; that is how math with floating-point numbers work.

Anyway, the standard way is with Newton's method. This is about the same as using Taylor's series, the other way that comes to mind immediately.

DATE_FORMAT(FROM_UNIXTIME(`orderdate`), '%Y-%m-%d %H:%i:%s') as "Date" FROM `orders`

This is the ultimate solution if the given date is in encoded format like 1300464000

For anyone reading this who is using EclipseLink for JPA 2.0, here are the two annotations I had to use to get JPA to persist data, where "MySequenceGenerator" is whatever name you want to give the generator, "myschema" is the name of the schema in your database that contains the sequence object, and "mysequence" is the name of the sequence object in the database.

@GeneratedValue(strategy= GenerationType.SEQUENCE, generator="MySequenceGenerator")
@SequenceGenerator(allocationSize=1, schema="myschema",  name="MySequenceGenerator", sequenceName = "mysequence")

For those using EclipseLink (and possibly other JPA providers), it is CRITICAL that you set the allocationSize attribute to match the INCREMENT value defined for your sequence in the database. If you don't, you'll get a generic persistence failure, and waste a good deal of time trying to track it down, like I did. Here is the reference page that helped me overcome this challenge:

http://wiki.eclipse.org/EclipseLink/Examples/JPA/PrimaryKey#Using_Sequence_Objects

Also, to give context, here is what we're using:

Java 7 Glassfish 3.1 PostgreSQL 9.1 PrimeFaces 3.2/JSF 2.1

Also, for laziness' sake, I built this in Netbeans with the wizards for generating Entities from DB, Controllers from Entities, and JSF from Entities, and the wizards (obviously) do not know how to deal with sequence-based ID columns, so you'll have to manually add these annotations.

Simply:

/^([^0-9]*)$/

That pattern matches any number of characters that is not 0 through 9.

I recommend checking out http://regexpal.com/. It will let you easily test out a regex.

"Timeline (responsive)" snippet:

This looks very, very close to what your example shows. The bootstrap snippet linked below covers all the bases you are looking for. I've been considering it myself, with the same requirements you have ( especially responsiveness ). This morphs well between screen sizes and devices.

You can fork this and use it as a great starting point for your specific expectations:

• http://bootsnipp.com/snippets/featured/timeline-responsive

Here are two screenshots I took for you... wide and thin:

In my particular case it was easier to do this:

 panel.setOpaque(true);
 panel.setBackground(new Color(0,0,0,0,)): // any color with alpha 0 (in this case the color is black

Yes the second syntax is fine.

Have you tried using the SPF wizard? https://www.spfwizard.net/

It can quickly generate basic and complex SPF records.

I've modified Greg's answer to suit my case, and it works. Here it is:

$("#note-items").children('.active').hide('slow', function(){ $("#note-items").children('.active').remove(); });

I don't know if you can do this with find, but an alternate solution would be to create a shell script and to run this with find.

lastline.sh:

echo $(tail -1 $1),$1

Make the script executable

chmod +x lastline.sh

Use find:

find . -name "*.txt" -exec ./lastline.sh {} \;

Best option is create new table with same properties

CREATE TABLE <NEW.NAME.TABLE> LIKE <TABLE.CRASHED>;
INSERT INTO <NEW.NAME.TABLE> SELECT * FROM <TABLE.CRASHED>;

Rename NEW.NAME.TABLE and TABLE.CRASH

RENAME TABLE <TABLE.CRASHED> TO <TABLE.CRASHED.BACKUP>;
RENAME TABLE <NEW.NAME.TABLE> TO <TABLE.CRASHED>;

After work well, delete

DROP TABLE <TABLE.CRASHED.BACKUP>;

Nobody did point the subtle difference in the semantics of the functions name() and local-name().

• name(someNode) returns the full name of the node, and that includes the prefix and colon in case the node is an element or an attribute.
• local-name(someNode) returns only the local name of the node, and that doesn't include the prefix and colon in case the node is an element or an attribute.

Therefore, in situations where a name may belong to two different namespaces, one must use the name() function in order for these names to be still distinguished.

And, BTW, it is possible to specify both functions without any argument:

name() is an abbreviation for name(.)

local-name() is an abbreviation for local-name(.)

Finally, do remember that not only elements and attributes have names, these two functions can also be used on PIs and on these they are identical).

I think there is missing one important aspect:

$('#some-text-area').val('test');

works only when there is an ID selector (#)

for class selector there is an option to use native value like:

$('.some-text-area')[0].value = 'test';

=IIF(fields!column.value =Condition,"Red","Black")

SQLDataReaders are forward-only. You're essentially doing this:

count++;  // initially 1
.DataBind(); //consuming all the records

//next iteration on
.Read()
//we've now come to end of resultset, thanks to the DataBind()
//count is still 1 

You could do this instead:

if (reader.HasRows)
{
    rep.DataSource = reader;
    rep.DataBind();
}
int count = rep.Items.Count; //somehow count the num rows/items `rep` has.

Since the value of $var is the empty string, this:

if [ $var == $var1 ]; then

expands to this:

if [ == abcd ]; then

which is a syntax error.

You need to quote the arguments:

if [ "$var" == "$var1" ]; then

You can also use = rather than ==; that's the original syntax, and it's a bit more portable.

If you're using bash, you can use the [[ syntax, which doesn't require the quotes:

if [[ $var = $var1 ]]; then

Even then, it doesn't hurt to quote the variable reference, and adding quotes:

if [[ "$var" = "$var1" ]]; then

might save a future reader a moment trying to remember whether [[ ... ]] requires them.

The spaceship method is useful when you define it in your own class and include the Comparable module. Your class then gets the >, < , >=, <=, ==, and between? methods for free.

class Card
  include Comparable
  attr_reader :value

  def initialize(value)
    @value = value
  end

  def <=> (other) #1 if self>other; 0 if self==other; -1 if self<other
    self.value <=> other.value
  end

end

a = Card.new(7)
b = Card.new(10)
c = Card.new(8)

puts a > b # false
puts c.between?(a,b) # true

# Array#sort uses <=> :
p [a,b,c].sort # [#<Card:0x0000000242d298 @value=7>, #<Card:0x0000000242d248 @value=8>, #<Card:0x0000000242d270 @value=10>]

In the past, I've used a .cmd script I found on the Internet. I hate the way localization normally messes with dates. Anytime you have dates in filenames (or anywhere else, if I may be so bold) I figure you want them in ISO 8601 format:

2015-02-19T14:54:51Z

or something else that has Y M D H M in that order, such as

2015-02-19 14:54

because it fixes the MDY / DMY ambiguity and because it's sortable as text.

I don't know where I got that .cmd script, but it may have been http://ss64.com/nt/syntax-getdate.html, which works beautifully on my YYYY-MM-DD Windows 8.1 and on a M/D/YYYY vanilla install of Windows 7. Both give the same format:

2015-02-09 04:43

I think the solutions aren't correct 100% I would use ceil instead of floor, round will work but it isn't the right operation.

function dateDiff(str1, str2){
    var diff = Date.parse(str2) - Date.parse(str1); 
    return isNaN(diff) ? NaN : {
        diff: diff,
        ms: Math.ceil(diff % 1000),
        s: Math.ceil(diff / 1000 % 60),
        m: Math.ceil(diff / 60000 % 60),
        h: Math.ceil(diff / 3600000 % 24),
        d: Math.ceil(diff / 86400000)
    };
}

Another option is to hide based on bootstraps "sr-only" class. If you wrap the text in a span with the class "sr-only" then the text will not be displayed, but screen readers will still have access to it. So you would have:

<li><a href="somehwere"><span class="sr-only">Link text</span></a></li>

If you are not using bootstrap, still keep the above, but also add the below css to define the "sr-only" class:

.sr-only {position: absolute;  width: 1px;  height: 1px;  padding: 0;  margin: -1px;  overflow: hidden;  clip: rect(0 0 0 0);  border: 0; }

At the first site is a dropdown field to select the language of phpmyadmin.

In the config.inc.php you can set:

$cfg['Lang'] = '';

More details you can find in the documentation: http://www.phpmyadmin.net/documentation/

Personally, I'd return the full, native datetime value and format this in the client code.

That way, you can use the user's locale setting to give the correct meaning to that user.

"11/12" is ambiguous. Is it:

• 12th November
• 11th December

When you make the call to gcc it should say

g++ -Wall -I/home/alwin/Development/Calculator/ -L/opt/lib main.cpp -lcalc -o calculator

not -libcalc.so 

I have a similar problem with auto-generated makes.

You can create a soft link from your compile directory to the library directory. Then the library becomes "local".

cd /compile/directory

ln -s  /path/to/libcalc.so libcalc.so

Set a minimum width at the top most layout.

android:minWidth="300dp"

For example:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent"
  xmlns:android="http://schemas.android.com/apk/res/android" android:minWidth="300dp">

<!-- Put remaining contents here -->

</LinearLayout>

With the "classic" method, if the cast fails, an InvalidCastException is thrown. With the as method, it results in null, which can be checked for, and avoid an exception being thrown.

Also, you can only use as with reference types, so if you are typecasting to a value type, you must still use the "classic" method.

Note:

The as method can only be used for types that can be assigned a null value. That use to only mean reference types, but when .NET 2.0 came out, it introduced the concept of a nullable value type. Since these types can be assigned a null value, they are valid to use with the as operator.

All the answers above are correct, but I think this is the easiest example possible:

public class ExampleActivity extends Activity {
    private Handler handler;
    private ProgressBar progress;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        progress = (ProgressBar) findViewById(R.id.progressBar1);
        handler = new Handler();
    }

    public void clickAButton(View view) {
        // Do something that takes a while
        Runnable runnable = new Runnable() {
            @Override
            public void run() {
                handler.post(new Runnable() { // This thread runs in the UI
                    @Override
                    public void run() {
                        progress.setProgress("anything"); // Update the UI
                    }
                });
            }
        };
        new Thread(runnable).start();
    }
}

What this does is update a progress bar in the UI thread from a completely different thread passed through the post() method of the handler declared in the activity.

Hope it helps!

The ruby downcase method returns a string with its uppercase letters replaced by lowercase letters.

You can download spark from here:

http://spark.apache.org/downloads.html

I recommend you this version: Hadoop 2 (HDP2, CDH5)

Since version 1.0.0 there are .cmd scripts to run spark in windows.

Unpack it using 7zip or similar.

To start you can execute /bin/spark-shell.cmd --master local[2]

To configure your instance, you can follow this link: http://spark.apache.org/docs/latest/

Do not type cast. Never. Use type guards:

const e = document.getElementsByName("script")[0];
if (!(e instanceof HTMLScriptElement)) 
  throw new Error(`Expected e to be an HTMLScriptElement, was ${e && e.constructor && e.constructor.name || e}`);
// locally TypeScript now types e as an HTMLScriptElement, same as if you casted it.

Let the compiler do the work for you and get errors when your assumptions turn out wrong.

It may look overkill in this case, but it will help you a lot if you come back later and change the selector, like adding a class that is missing in the dom, for example.

The apiKey in this configuration snippet just identifies your Firebase project on the Google servers. It is not a security risk for someone to know it. In fact, it is necessary for them to know it, in order for them to interact with your Firebase project. This same configuration data is also included in every iOS and Android app that uses Firebase as its backend.

In that sense it is very similar to the database URL that identifies the back-end database associated with your project in the same snippet: https://<app-id>.firebaseio.com. See this question on why this is not a security risk: How to restrict Firebase data modification?, including the use of Firebase's server side security rules to ensure only authorized users can access the backend services.

If you want to learn how to secure all data access to your Firebase backend services is authorized, read up on the documentation on Firebase security rules. These rules control access to file storage and database access, and are enforced on the Firebase servers. So no matter if it's your code, or somebody else's code that uses you configuration data, it can only do what the security rules allow it to do.

For another explanation of what Firebase uses these values for, and for which of them you can set quotas, see the Firebase documentation on using and managing API keys.

If you'd like to reduce the risk of committing this configuration data to version control, consider using the SDK auto-configuration of Firebase Hosting. While the keys will still end up in the browser in the same format, they won't be hard-coded into your code anymore with that.

Felipsmartins is correct.

It is worth mentioning that it is because you cannot really use the -d/--data option if this is not a POST request. But this is still possible if you use the -G option.

Which means you can do this:

curl -X DELETE -G 'http://localhost:5000/locations' -d 'id=3'

Here it is a bit silly but when you are on the command line and you have a lot of parameters, it is a lot tidier.

I am saying this because cURL commands are usually quite long, so it is worth making it on more than one line escaping the line breaks.

curl -X DELETE -G \
'http://localhost:5000/locations' \
-d id=3 \
-d name=Mario \
-d surname=Bros

This is obviously a lot more comfortable if you use zsh. I mean when you need to re-edit the previous command because zsh lets you go line by line. (just saying)

Hope it helps.

onActivityCreated() - Deprecated

onActivityCreated() is now deprecated as Fragments Version 1.3.0-alpha02

The onActivityCreated() method is now deprecated. Code touching the fragment's view should be done in onViewCreated() (which is called immediately before onActivityCreated()) and other initialization code should be in onCreate(). To receive a callback specifically when the activity's onCreate() is complete, a LifeCycleObserver should be registered on the activity's Lifecycle in onAttach(), and removed once the onCreate() callback is received.

I solved this issue by doing like that:

insert into my_table(my_field_0, ..., my_field_n) values(my_value_0, ..., my_value_n)

It is only required if you aren't using the default values for version and encoding (which you are in that example).

To answer this not from an aesthetical but performance-oriented point of view, I've put all of the above suggestions through a benchmark. To be precise, I've considered the suggestions

• x[length(x)]
• mylast(x), where mylast is a C++ function implemented through Rcpp,
• tail(x, n=1)
• dplyr::last(x)
• x[end(x)[1]]]
• rev(x)[1]

and applied them to random vectors of various sizes (10^3, 10^4, 10^5, 10^6, and 10^7). Before we look at the numbers, I think it should be clear that anything that becomes noticeably slower with greater input size (i.e., anything that is not O(1)) is not an option. Here's the code that I used:

Rcpp::cppFunction('double mylast(NumericVector x) { int n = x.size(); return x[n-1]; }')
options(width=100)
for (n in c(1e3,1e4,1e5,1e6,1e7)) {
  x <- runif(n);
  print(microbenchmark::microbenchmark(x[length(x)],
                                       mylast(x),
                                       tail(x, n=1),
                                       dplyr::last(x),
                                       x[end(x)[1]],
                                       rev(x)[1]))}

It gives me

This immediately rules out anything involving rev or end since they're clearly not O(1) (and the resulting expressions are evaluated in a non-lazy fashion). tail and dplyr::last are not far from being O(1) but they're also considerably slower than mylast(x) and x[length(x)]. Since mylast(x) is slower than x[length(x)] and provides no benefits (rather, it's custom and does not handle an empty vector gracefully), I think the answer is clear: Please use x[length(x)].

As mentioned by @superjos in comments use

mocha --recursive "some_dir"

Seems like a Permissions Issue. I was facing the same error. But when I ran it from the root account, it worked. So either give the read permission to the file using chmod (in linux) or run your script after logging in as a root user.

Error-Handling with SQL Stored Procedures

TRY/CATCH error handling can take place either within or outside of a procedure (or both). The examples below demonstrate error handling in both cases.

If you want to experiment further, you can fork the query on Stack Exchange Data Explorer.

_{(This uses a temporary stored procedure... we can't create regular SP's on SEDE, but the functionality is the same.)}

--our Stored Procedure
create procedure #myProc as --we can only create #temporary stored procedures on SEDE. 
  begin
    BEGIN TRY
      print 'This is our Stored Procedure.'
      print 1/0                          --<-- generate a "Divide By Zero" error.
      print 'We are not going to make it to this line.'
    END TRY

    BEGIN CATCH
      print 'This is the CATCH block within our Stored Procedure:'
          + ' Error Line #'+convert(varchar,ERROR_LINE())
          + ' of procedure '+isnull(ERROR_PROCEDURE(),'(Main)')
      --print 1/0                        --<-- generate another "Divide By Zero" error.

  print 'This is our MAIN Procedure.'
  execute #myProc  --execute the Stored Procedure
      --print 1/0                        --<-- generate another "Divide By Zero" error.

          + ' Error Line #'+convert(varchar,ERROR_LINE())
          + ' of procedure '+isnull(ERROR_PROCEDURE(),'(Main)')
END CATCH

Here's the result of running the above sql as-is:

This is our MAIN Procedure.
This is our Stored Procedure.
This is the CATCH block within our Stored Procedure: Error Line #5 of procedure #myProc
Now our MAIN sql code block continues.

¹ Uncommenting the "additional error line" from the Stored Procedure's CATCH block will produce:

This is our MAIN procedure.
This is our Stored Procedure.
This is the CATCH block within our Stored Procedure: Error Line #5 of procedure #myProc
This is the CATCH block for our MAIN sql code block: Error Line #13 of procedure #myProc

² Uncommenting the "additional error line" from the MAIN procedure will produce:

This is our MAIN Procedure.
This is our Stored Pprocedure.
This is the CATCH block within our Stored Procedure: Error Line #5 of procedure #myProc
This is the CATCH block for our MAIN sql code block: Error Line #4 of procedure (Main)

Use a single procedure for error handling

On topic of stored procedures and error handling, it can be helpful (and tidier) to use a single, dynamic, stored procedure to handle errors for multiple other procedures or code sections.

Here's an example:

--our error handling procedure
create procedure #myErrorHandling as
  begin
    print ' Error #'+convert(varchar,ERROR_NUMBER())+': '+ERROR_MESSAGE()  
    print ' occurred on line #'+convert(varchar,ERROR_LINE())
         +' of procedure '+isnull(ERROR_PROCEDURE(),'(Main)')
    if ERROR_PROCEDURE() is null       --check if error was in MAIN Procedure
      print '*Execution cannot continue after an error in the MAIN Procedure.'
  end
go

create procedure #myProc as     --our test Stored Procedure
  begin
    BEGIN TRY
      print 'This is our Stored Procedure.'
      print 1/0                       --generate a "Divide By Zero" error.
      print 'We will not make it to this line.'
    END TRY
    BEGIN CATCH
     execute #myErrorHandling
    END CATCH
  end
go

BEGIN TRY                       --our MAIN Procedure
  print 'This is our MAIN Procedure.'
  execute #myProc                     --execute the Stored Procedure
  print '*The error halted the procedure, but our MAIN code can continue.'
  print 1/0                           --generate another "Divide By Zero" error.
  print 'We will not make it to this line.'
END TRY
BEGIN CATCH
  execute #myErrorHandling
END CATCH

Example Output: _{^{(This query can be forked on SEDE here.)}}

This is our MAIN procedure.
This is our stored procedure.

Documentation:

In the scope of a TRY/CATCH block, the following system functions can be used to obtain information about the error that caused the CATCH block to be executed:

• ERROR_NUMBER() returns the number of the error.
• ERROR_SEVERITY() returns the severity.
• ERROR_STATE() returns the error state number.
• ERROR_PROCEDURE() returns the name of the stored procedure or trigger where the error occurred.
• ERROR_LINE() returns the line number inside the routine that caused the error.
• ERROR_MESSAGE() returns the complete text of the error message. The text includes the values supplied for any substitutable parameters, such as lengths, object names, or times.

^(Source)

Note that there are two types of SQL errors: Terminal and Catchable. TRY/CATCH will [obviously] only catch the "Catchable" errors. This is one of a number of ways of learning more about your SQL errors, but it probably the most useful.

It's "better to fail now" (during development) compared to later because, as Homer says . . .

For the first case you propose you can use: '[[:blank:]]+[A-Z0-9]+[[:blank:]]+', for example:

echo "The thing P1 must connect to the J236 thing in the Foo position" | grep -oE '[[:blank:]]+[A-Z0-9]+[[:blank:]]+'

In the second case maybe you need to use something else and not a regex, maybe a script with a dictionary of technical words...

Cheers, Fernando

To do this using data.table, I found that the following works. Unfortunately, the link does not work anymore, so I used a link for another data set.

library(data.table)
temp <- tempfile()
download.file("https://www.bls.gov/tus/special.requests/atusact_0315.zip", temp)
timeUse <- fread(unzip(temp, files = "atusact_0315.dat"))
rm(temp)

I know this is possible in a single line since you can pass bash scripts to fread, but I am not sure how to download a .zip file, extract, and pass a single file from that to fread.

If you want to use less code, you can also use the norm in the stats package (the 'F' stands for Forbenius, which is the Euclidean norm):

norm(matrix(x1-x2), 'F')

While this may look a bit neater, it's not faster. Indeed, a quick test on very large vectors shows little difference, though so12311's method is slightly faster. We first define:

set.seed(1234)
x1 <- rnorm(300000000)
x2 <- rnorm(300000000)

Then testing for time yields the following:

> system.time(a<-sqrt(sum((x1-x2)^2)))
user  system elapsed 
1.02    0.12    1.18 
> system.time(b<-norm(matrix(x1-x2), 'F'))
user  system elapsed 
0.97    0.33    1.31 

Try this:

[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12

Install-PackageProvider NuGet -Force

Set-PSRepository PSGallery -InstallationPolicy Trusted

You need to remove the / before the [. Predicates (the parts in [ ]) shouldn't have slashes immediately before them. Also, to select the Employee element itself, you should leave off the /text() at the end or otherwise you'd just be selecting the whitespace text values immediately under the Employee element.

//Employee[@id='4']

Edit: As Jens points out in the comments, // can be very slow because it searches the entire document for matching nodes. If the structure of the documents you're working with is going to be consistent, you are probably best off using a full path, for example:

/Employees/Employee[@id='4']

^\d{5}(?:[-\s]\d{4})?$

• ^ = Start of the string.
• \d{5} = Match 5 digits (for condition 1, 2, 3)
• (?:…) = Grouping
• [-\s] = Match a space (for condition 3) or a hyphen (for condition 2)
• \d{4} = Match 4 digits (for condition 2, 3)
• …? = The pattern before it is optional (for condition 1)
• $ = End of the string.

I found it!

Simply print out $Error[0] for the last error message.

Change your black and white IDs to classes instead (duplicate IDs are invalid), add 2 buttons with the proper IDs, and do this:

var rows = $('table.someclass tr');

$('#showBlackButton').click(function() {
    var black = rows.filter('.black').show();
    rows.not( black ).hide();
});

$('#showWhiteButton').click(function() {
    var white = rows.filter('.white').show();
    rows.not( white ).hide();
});

$('#showAll').click(function() {
    rows.show();
});

<button id="showBlackButton">show black</button>
<button id="showWhiteButton">show white</button>
<button id="showAll">show all</button>

<table class="someclass" border="0" cellpadding="0" cellspacing="0" summary="bla bla bla">
    <caption>bla bla bla</caption>
    <thead>
          <tr class="black">
            ...
          </tr>
    </thead>
    <tbody>
        <tr class="white">
            ...
        </tr>
        <tr class="black">
           ...
        </tr>
    </tbody>
</table>

It uses the filter()^[docs] method to filter the rows with the black or white class (depending on the button).

Then it uses the not()^[docs] method to do the opposite filter, excluding the black or white rows that were previously found.

EDIT: You could also pass a selector to .not() instead of the previously found set. It may perform better that way:

rows.not( `.black` ).hide();

// ...

rows.not( `.white` ).hide();

...or better yet, just keep a cached set of both right from the start:

var rows = $('table.someclass tr');
var black = rows.filter('.black');
var white = rows.filter('.white');

$('#showBlackButton').click(function() {
    black.show();
    white.hide();
});

$('#showWhiteButton').click(function() {
    white.show();
    black.hide();
});

If you use <tbody> or <tfoot> in your table, you'll have to use the following syntax or you'll get a incorrect value:

var rowCount = $('#myTable >tbody >tr').length;

If your context is android application , then make sure your android device time is set to current date and time. The underlying exception is "The SSL certificates was not getting authenticated."

SIMPLE ANSWER:

   onclick="functionName(ID.value);

Where ID is the ID of the input field.

Create the following function

CREATE OR REPLACE FUNCTION isnull(text, text) RETURNS text AS 'SELECT (CASE (SELECT $1 "
    "is null) WHEN true THEN $2 ELSE $1 END) AS RESULT' LANGUAGE 'sql'

And it'll work.

You may to create different versions with different parameter types.

Execution is top-down. First come, first served.

If execution sequence is important, combine them.

Aggregation vs Composition

Aggregation implies a relationship where the child can exist independently of the parent. For example, Bank and Employee, delete the Bank and the Employee still exist.

whereas Composition implies a relationship where the child cannot exist independent of the parent. Example: Human and heart, heart don’t exist separate to a Human.

Aggregation relation is “has-a” and composition is “part-of” relation.

Composition is a strong Association whereas Aggregation is a weak Association.

Here is a simple function to convert Bytes to KB, MB, GB, TB :

# Size in Bytes
$size = 14903511;
# Call this function to convert bytes to KB/MB/GB/TB
echo convertToReadableSize($size);
# Output => 14.2 MB

function convertToReadableSize($size){
  $base = log($size) / log(1024);
  $suffix = array("", "KB", "MB", "GB", "TB");
  $f_base = floor($base);
  return round(pow(1024, $base - floor($base)), 1) . $suffix[$f_base];
}

To be more precise the shebang #!, when it is the first two bytes of an executable (x mode) file, is interpreted by the execve(2) system call (which execute programs). But POSIX specification for execve don't mention the shebang.

It must be followed by a file path of an interpreter executable (which BTW could even be relative, but most often is absolute).

A nice trick (or perhaps not so nice one) to find an interpreter (e.g. python) in the user's $PATH is to use the env program (always at /usr/bin/env on all Linux) like e.g.

 #!/usr/bin/env python

Any ELF executable can be an interpreter. You could even use #!/bin/cat or #!/bin/true if you wanted to! (but that would be often useless)

I like this to have enum in the dayNames. To reduce typing, we can do the following:

#define EP(x) [x] = #x  /* ENUM PRINT */

const char* dayNames[] = { EP(Sunday), EP(Monday)};

These will also redirect both:

yourcommand  &> /dev/null

yourcommand  >& /dev/null

though the bash manual says the first is preferred.

Figure sizes are specified in inches and can be included as a global option of the document output format. For example:

---
title: "My Document"
output:
  html_document:
    fig_width: 6
    fig_height: 4
---

And the plot's size in the graphic device can be increased at the chunk level:

```{r, fig.width=14, fig.height=12}          #Expand the plot width to 14 inches

ggplot(aes(x=mycolumn1, y=mycolumn2)) +     #specify the x and y aesthetic
geom_line(size=2) +                         #makes the line thicker
theme_grey(base_size = 25)                  #increases the size of the font
```

You can also use the out.width and out.height arguments to directly define the size of the plot in the output file:

```{r, out.width="200px", out.height="200px"} #Expand the plot width to 200 pixels

ggplot(aes(x=mycolumn1, y=mycolumn2)) +     #specify the x and y aesthetic
geom_line(size=2) +                         #makes the line thicker
theme_grey(base_size = 25)                  #increases the size of the font
```

If you want to match the two words in either order, use:

gci C:\Logs| select-string -pattern '(VendorEnquiry.*Failed)|(Failed.*VendorEnquiry)'

If Failed always comes after VendorEnquiry on the line, just use:

gci C:\Logs| select-string -pattern '(VendorEnquiry.*Failed)'

function my_date_parse($date)
{
        if (!preg_match('/^(\d+)\.(\d+)\.(\d+)$/', $date, $m))
                return false;

        $day = $m[1];
        $month = $m[2];
        $year = $m[3];

        if (!checkdate($month, $day, $year))
                return false;

        return "$year-$month-$day";
}

An Example Using Your Own Data

You can avoid having your filename embedded in the NUMOFLINES variable by using redirection from JAVA_TAGS_FILE, rather than passing the filename as an argument to wc. For example:

NUMOFLINES=$(wc -l < "$JAVA_TAGS_FILE")

Explanation: Use Pipes or Redirection to Avoid Filenames in Output

The wc utility will not print the name of the file in its output if input is taken from a pipe or redirection operator. Consider these various examples:

# wc shows filename when the file is an argument
$ wc -l /etc/passwd
41 /etc/passwd

# filename is ignored when piped in on standard input
$ cat /etc/passwd | wc -l
41

# unusual redirection, but wc still ignores the filename
$ < /etc/passwd wc -l
41

# typical redirection, taking standard input from a file
$ wc -l < /etc/passwd
41

As you can see, the only time wc will print the filename is when its passed as an argument, rather than as data on standard input. In some cases, you may want the filename to be printed, so it's useful to understand when it will be displayed.

It is valid.

However, standard practice is to use href="#" or sometimes href="javascript:;".

The ASCII vertical tab (\x0B)is still used in some databases and file formats as a new line WITHIN a field. For example:

• In the .mer file format to allow new lines within a data field,
• FileMaker databases can use vertical tabs as a linefeed (see https://support.microsoft.com/en-gb/kb/59096).

You cannot SELECT .. INTO .. a TABLE VARIABLE. The best you can do is create it first, then insert into it. Your 2nd snippet has to be

DECLARE @TempCustomer TABLE
(
   CustomerId uniqueidentifier,
   FirstName nvarchar(100),
   LastName nvarchar(100),
   Email nvarchar(100)
);
INSERT INTO 
    @TempCustomer 
SELECT 
    CustomerId, 
    FirstName, 
    LastName, 
    Email 
FROM 
    Customer
WHERE 
    CustomerId = @CustomerId

The correct syntax for updating the password using SQL Developer is:

alter user user_name identified by new_password replace old_password ;

You can check more options for this command here: ALTER USER-Oracle DOCS

This error is caused by binary data being inserted into a buffer. To solve this problem, you should insert one statement in your code.

This statement is:

obj_FileStream.Read(Img, 0, Convert.ToInt32(obj_FileStream.Length));

Example:

FileStream obj_FileStream = new FileStream(str_ImagePath, FileMode.OpenOrCreate, FileAccess.Read);
Byte[] Img = new Byte[obj_FileStream.Length];
obj_FileStream.Read(Img, 0, Convert.ToInt32(obj_FileStream.Length));         
dt_NewsFeedByRow.Rows[0][6] = Img;

try adding

position:relative

to your body styles. Whenever positioning anything absolutely, you need one of the parent containers to be positioned relative as this will make the item be positioned absolute to the parent container that is relative.

As you had no relative elements, the css will not know what the div is absolutely position to and therefore will not know what to take 100% height of

Simply install Microsot.ReportViewer.2012.Runtime nuget package as shown in this answer https://stackoverflow.com/a/33014040/2198830

This is useful if you want to do nothing if it does exist but create it if it doesn't exist.

def get_var
  @var ||= SomeClass.new()
end

This only creates the new instance once. After that it just keeps returning the var.

There is no difference between the %i and %d format specifiers for printf. We can see this by going to the draft C99 standard section 7.19.6.1 The fprintf function which also covers printf with respect to format specifiers and it says in paragraph 8:

The conversion specifiers and their meanings are:

and includes the following bullet:

d,i     The int argument is converted to signed decimal in the style
        [-]dddd. The precision specifies the minimum number of digits to
        appear; if the value being converted can be represented in fewer
        digits, it is expanded with leading zeros. The default precision is
        1. The result of converting a zero value with a precision of zero is
        no characters.

On the other hand for scanf there is a difference, %d assume base 10 while %i auto detects the base. We can see this by going to section 7.19.6.2 The fscanf function which covers scanf with respect to format specifier, in paragraph 12 it says:

The conversion specifiers and their meanings are:

and includes the following:

d     Matches an optionally signed decimal integer, whose format is the
      same as expected for the subject sequence of the strtol function with
      the value 10 for the base argument. The corresponding argument shall
      be a pointer to signed integer.

i     Matches an optionally signed integer, whose format is the same as
      expected for the subject sequence of the strtol function with the
      value 0 for the base argument. The corresponding argument shall be a
      pointer to signed integer.

You can use .text-reset class to reset the color from default blue to anything you want. Hopefully this is helpful.

One of the most well known solutions is a variation of your solution number 3 that uses a pseudo element instead of a non-semantic html element.

It goes something like this...

.cf:after {
    content: " ";
    display: block;
    visibility: hidden;
    height: 0;
    clear: both;
}

You place that in your stylesheet, and all you need is to add the class 'cf' to the element containing the floats.

What I use is another variation which comes from Nicolas Gallagher.

It does the same thing, but it's shorter, looks neater, and maybe used to accomplish another thing that's pretty useful - preventing the child elements' margins from collapsing with it's parents' (but for that you do need something else - read more about it here http://nicolasgallagher.com/micro-clearfix-hack/ ).

.cf:after {
    content: " ";
    display: table;
    clear: float;
}

Typically, a thread is terminated when it's interrupted. So, why not use the native boolean? Try isInterrupted():

Thread t = new Thread(new Runnable(){
        @Override
        public void run() {
            while(!Thread.currentThread().isInterrupted()){
                // do stuff         
            }   
        }});
    t.start();

    // Sleep a second, and then interrupt
    try {
        Thread.sleep(1000);
    } catch (InterruptedException e) {}
    t.interrupt();

Negatives are your friend here:

SELECT Col1
FROM TABLE
WHERE Col1 like '%[^a-Z0-9]%'

Which says that you want any rows where Col1 consists of any number of characters, then one character not in the set a-Z0-9, and then any number of characters.

If you have a case sensitive collation, it's important that you use a range that includes both upper and lower case A, a, Z and z, which is what I've given (originally I had it the wrong way around. a comes before A. Z comes after z)

Or, to put it another way, you could have written your original WHERE as:

Col1 LIKE '[!@#$%]'

But, as you observed, you'd need to know all of the characters to include in the [].

I had the same problem but also wanted to get the content of the file (after the YAML front-matter).

This is the best solution I have found:

if (md = contents.match(/^(?<metadata>---\s*\n.*?\n?)^(---\s*$\n?)/m))
  self.contents = md.post_match
  self.metadata = YAML.load(md[:metadata])
end

HISTTIMEFORMAT="%d/%m/%y %H:%M "

For any commands typed prior to this, it will not help since they will just get a default time of when you turned history on, but it will log the time of any further commands after this.

If you want it to log history for permanent, you should put the following line in your ~/.bashrc

export HISTTIMEFORMAT="%d/%m/%y %H:%M "

Response.Write('... javascript that opens a window...')

http://www.aspspider.com/qa/Question2714.aspx

You can also use myform.$invalid

E.g.

if($scope.myform.$invalid){return;}

Eek, don't do anything that complicated : )

Just filter() your tags. bool() returns False for empty strings, so instead of

new_tag_list = f1.striplist(tag_string.split(",") + selected_tags)

you should write

new_tag_list = filter(bool, f1.striplist(tag_string.split(",") + selected_tags))

or better yet, put this logic inside striplist() so that it doesn't return empty strings in the first place.

You could also send your testers the apk that is signed with your debug key. You can find that in the bin folder of your project after building in debug mode.

if you are using extracted tomcat then,

startup.sh and shutdown.sh are two script located in TOMCAT/bin/ to start and shutdown tomcat, You could use that

if tomcat is installed then

/etc/init.d/tomcat5.5 start
/etc/init.d/tomcat5.5 stop
/etc/init.d/tomcat5.5 restart

You try to instantiate an object of the Friends class like this:

Friends f = new Friends(friendsName, friendsAge);

The class does not have a constructor that takes parameters. You should either add the constructor, or create the object using the constructor that does exist and then use the set-methods. For example, instead of the above:

Friends f = new Friends();
f.setName(friendsName);
f.setAge(friendsAge);

JavaScript doesn’t support namespace by default. So if you create any element(function, method, object, variable) then it becomes global and pollute the global namespace. Let's take an example of defining two functions without any namespace,

function func1() {
    console.log("This is a first definition");

}
function func1() {
    console.log("This is a second definition");
}
func1(); // This is a second definition

It always calls the second function definition. In this case, namespace will solve the name collision problem.

In the interest of completeness, for people looking for a more modern solution, in Oracle 12c there are some new features including better paging and top handling.

Paging

The paging looks like this:

SELECT *
FROM user
ORDER BY first_name
OFFSET 5 ROWS FETCH NEXT 10 ROWS ONLY;

Top N Records

Getting the top records looks like this:

SELECT *
FROM user
ORDER BY first_name
FETCH FIRST 5 ROWS ONLY

Notice how both the above query examples have ORDER BY clauses. The new commands respect these and are run on the sorted data.

I couldn't find a good Oracle reference page for FETCH or OFFSET but this page has a great overview of these new features.

Performance

As @wweicker points out in the comments below, performance is an issue with the new syntax in 12c. I didn't have a copy of 18c to test if Oracle has since improved it.

Interestingly enough, my actual results were returned slightly quicker the first time I ran the queries on my table (113 million+ rows) for the new method:

• New method: 0.013 seconds.
• Old method: 0.107 seconds.

However, as @wweicker mentioned, the explain plan looks much worse for the new method:

• New method cost: 300,110
• Old method cost: 30

The new syntax caused a full scan of the index on my column, which was the entire cost. Chances are, things get much worse when limiting on unindexed data.

Let's have a look when including a single unindexed column on the previous dataset:

• New method time/cost: 189.55 seconds/998,908
• Old method time/cost: 1.973 seconds/256

Summary: use with caution until Oracle improves this handling. If you have an index to work with, perhaps you can get away with using the new method.

Hopefully I'll have a copy of 18c to play with soon and can update

I am surprised the wooledge guide on empty directories hasn't been mentioned. This guide, and all of wooledge really, is a must read for shell type questions.

Of note from that page:

Never try to parse ls output. Even ls -A solutions can break (e.g. on HP-UX, if you are root, ls -A does the exact opposite of what it does if you're not root -- and no, I can't make up something that incredibly stupid).

In fact, one may wish to avoid the direct question altogether. Usually people want to know whether a directory is empty because they want to do something involving the files therein, etc. Look to the larger question. For example, one of these find-based examples may be an appropriate solution:

   # Bourne
   find "$somedir" -type f -exec echo Found unexpected file {} \;
   find "$somedir" -maxdepth 0 -empty -exec echo {} is empty. \;  # GNU/BSD
   find "$somedir" -type d -empty -exec cp /my/configfile {} \;   # GNU/BSD

Most commonly, all that's really needed is something like this:

   # Bourne
   for f in ./*.mpg; do
        test -f "$f" || continue
        mympgviewer "$f"
    done

In other words, the person asking the question may have thought an explicit empty-directory test was needed to avoid an error message like mympgviewer: ./*.mpg: No such file or directory when in fact no such test is required.

While possible, it's potentially very risky - if you attempt to commit changes to the repository from 2 different locations simultaneously, you'll get a giant mess due to the file conflicts. Get a free private SVN host somewhere, or set up a repository on a server you have access to.

Edit based on a recent experience: If you have files open that are managed by Dropbox and your computer crashes, your files may be truncated to 0 bytes. If this happens to the files which manage your repository, your repository will be corrupted. If you discover this soon enough, you can use Dropbox's "recover old version" feature but you're still taking a risk.

You could also insert the results (or top 10 results) into a temp table and get the columns from the temp table (as long as the column names are all different).

SELECT TOP 10 *
INTO #TempTable
FROM <DataSource>

Then use:

EXEC tempdb.dbo.sp_help N'#TempTable';

or

SELECT * 
FROM tempdb.sys.columns 
WHERE [object_id] = OBJECT_ID(N'tempdb..#TempTable');

Extrapolated from Aaron's answer here.

SELECT 
    * 
FROM 
    table 
WHERE 
    column < (SELECT max(columnq) FROM table) 
ORDER BY 
    column DESC LIMIT 1

sshpass with better security

I stumbled on this thread while looking for a way to ssh into a bogged-down server -- it took over a minute to process the SSH connection attempt, and timed out before I could enter a password. In this case, I wanted to be able to supply my password immediately when the prompt was available.

(And if it's not painfully clear: with a server in this state, it's far too late to set up a public key login.)

sshpass to the rescue. However, there are better ways to go about this than sshpass -p.

My implementation skips directly to the interactive password prompt (no time wasted seeing if public key exchange can happen), and never reveals the password as plain text.

#!/bin/sh
# preempt-ssh.sh
# usage: same arguments that you'd pass to ssh normally
echo "You're going to run (with our additions) ssh $@"

# Read password interactively and save it to the environment
read -s -p "Password to use: " SSHPASS 
export SSHPASS

# have sshpass load the password from the environment, and skip public key auth
# all other args come directly from the input
sshpass -e ssh -o PreferredAuthentications=keyboard-interactive -o PubkeyAuthentication=no "$@"

# clear the exported variable containing the password
unset SSHPASS

For adding multiple query params, this is what worked for me (from here https://forum.vuejs.org/t/vue-router-programmatically-append-to-querystring/3655/5).

an answer above was close … though with Object.assign it will mutate this.$route.query which is not what you want to do … make sure the first argument is {} when doing Object.assign

this.$router.push({ query: Object.assign({}, this.$route.query, { newKey: 'newValue' }) });

Because your question is geared towards a single table, you can use this:

EXEC sp_fkeys 'TableName'

I found it on SO here:

https://stackoverflow.com/a/12956348/652519

I found the information I needed pretty quickly. It lists the foreign key's table, column and name.

EDIT

Here's a link to the documentation that details the different parameters that can be used: https://docs.microsoft.com/en-us/sql/relational-databases/system-stored-procedures/sp-fkeys-transact-sql

#include<stdio.h>
main()
{
        int a[5] = {55,11,66,77,72};
        int max,min,i;
        int smax,smin;
        max = min = a[0];
        smax = smin = a[0];
        for(i=0;i<=4;i++)
        {
                if(a[i]>max)
                {
                        smax = max;
                        max = a[i];
                }
                if(max>a[i]&&smax<a[i])
                {
                        smax = a[i];
                }
        }
        printf("the first max element z %d\n",max);
        printf("the second max element z %d\n",smax);
}

Note that when using "git log -n 1 [branch_name]" option. -n returns only one line of log but order in which this is returned is not guaranteed. Following is extract from git-log man page

Commit Limiting

Besides specifying a range of commits that should be listed using the special notations explained in the     description, additional commit limiting may be applied.

Using more options generally further limits the output (e.g. --since=<date1> limits to commits newer than <date1>, and using it with --grep=<pattern> further limits to commits whose log message has a line that matches <pattern>), unless otherwise noted.

Note that these are applied before commit ordering and formatting options, such as --reverse.

-<number>
-n <number>

Here's a collection of scripts: http://webtecker.com/2008/03/26/collection-of-password-strength-scripts/

I think both of them rate the password and don't use jQuery... but I don't know if they have native support for disabling the form?

None of the above changes made any difference in my case. I could run TNS_PING in the command window but SQL Developer couldn't figure out where tnsnames.ora was.

The issue in my case (Windows 7 - 64 bit - Enterprise ) was that the Oracle installer pointed the Start menu shortcut to the wrong version of SQL Developer. There appear to be three SQL Developer instances that accompany the installer. One is in %ORACLE_HOME%\client_1\sqldeveloper\ and two are in %ORACLE_HOME%\client_1\sqldeveloper\bin\ .

The installer installed a start menu shortcut that pointed at a version in the bin directory that simply did not function. It would ask for a password every time I started SQL Developer, not remember choices I had made and displayed a blank list when I chose TNS as the connection mechanism. It also does not have the TNS Directory field in the Database advanced settings referenced in other posts.

I tossed the old Start shortcut and installed a shortcut to %ORACLE_HOME%\client_1\sqldeveloper\sqldeveloper.exe . That change fixed the problem in my case.

You can write different sheets as follows

$objPHPExcel = new PHPExcel();
$objPHPExcel->getProperties()->setCreator("creater");
$objPHPExcel->getProperties()->setLastModifiedBy("Middle field");
$objPHPExcel->getProperties()->setSubject("Subject");
$objWorkSheet = $objPHPExcel->createSheet();
$work_sheet_count=3;//number of sheets you want to create
$work_sheet=0;
while($work_sheet<=$work_sheet_count){ 
     if($work_sheet==0){
         $objWorkSheet->setTitle("Worksheet$work_sheet");
         $objPHPExcel->setActiveSheetIndex($work_sheet)->setCellValue('A1', 'SR No. In sheet 1')->getStyle('A1')->getFont()->setBold(true);
         $objPHPExcel->setActiveSheetIndex($work_sheet)->setCellValueByColumnAndRow($col++, $row++, $i++);//setting value by column and row indexes if needed
     }
     if($work_sheet==1){
         $objWorkSheet->setTitle("Worksheet$work_sheet");
         $objPHPExcel->setActiveSheetIndex($work_sheet)->setCellValue('A1', 'SR No. In sheet 2')->getStyle('A1')->getFont()->setBold(true);
         $objPHPExcel->setActiveSheetIndex($work_sheet)->setCellValueByColumnAndRow($col++, $row++, $i++);//setting value by column and row indexes if needed
     }
     if($work_sheet==2){
         $objWorkSheet = $objPHPExcel->createSheet($work_sheet_count);
         $objWorkSheet->setTitle("Worksheet$work_sheet");
         $objPHPExcel->setActiveSheetIndex($work_sheet)->setCellValue('A1', 'SR No. In sheet 3')->getStyle('A1')->getFont()->setBold(true);
         $objPHPExcel->setActiveSheetIndex($work_sheet)->setCellValueByColumnAndRow($col++, $row++, $i++);//setting value by column and row indexes if needed
     }
     $work_sheet++;
}

$filename='file-name'.'.xls'; //save our workbook as this file name
header('Content-Type: application/vnd.ms-excel'); //mime type
header('Content-Disposition: attachment;filename="'.$filename.'"'); //tell browser what's the file name
header('Cache-Control: max-age=0'); //no cach

$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5');
$objWriter->save('php://output');

Here is a great resource from Microsoft which includes a high level features overview for each .NET release since 1.0 up to the present day. It also include information about the associated Visual Studio release and Windows version compatibility.

.NET Framework Versions and Dependencies

I was getting a similar issue from the Apache Lounge 32 bit version. After downloading the 64 bit version, the issue was resolved.

Here is an excellent video explain the steps involved: https://www.youtube.com/watch?v=17qhikHv5hY

I think that the SQLPATH environment variable is the best way for this - if you have multiple paths, enter them separated by semi-colons (;). Keep in mind that if there are script files named the same in among the directories, the first one encountered (by order the paths are entered) will be executed, the second one will be ignored.

Found it!

ckeditor.js line #91 ... search for

B.config.enterMode==3?'div':'p'

change to

B.config.enterMode==3?'div':'' (NO P!)

Dump your cache and BAM!

As long as your file has consistent formatting (i.e. line-breaks), this is easy with just basic file IO and string operations:

with open('my_file.txt', 'rU') as in_file:
    data = in_file.read().split('\n')

That will store your data file as a list of items, one per line. To then put it into a file, you would do the opposite:

with open('new_file.txt', 'w') as out_file:
    out_file.write('\n'.join(data)) # This will create a string with all of the items in data separated by new-line characters

Hopefully that fits what you're looking for.

Actually you dont need to call document.getElementById() function to get access to your div.

You can use this object directly by id:

text = test.textContent || test.innerText;
alert(text);

Another possibility would be to set the Working Directory under the debugging options to be the directory that has that DLL.

Edit: I was going to mention using a batch file to start Visual Studio (and set the PATH variable in the batch file). So then did a bit of searching and see that this exact same question was asked not long ago in this post. The answer suggests the batch file option as well as project settings that apparently may do the job (I did not test it).

(new Double(d)).longValue() internally just does a cast, so there's no reason to create a Double object.

You don't really need the g at the end. So it becomes:

:%s/$/*

Or if you just want the * at the end of, say lines 14-18:

:14,18s/$/*

or

:14,18norm A*

All of the following commands are possible to change the port while running django:

python manage.py runserver 127.0.0.1:7000

python manage.py runserver 7000

python manage.py runserver 0:7000

Along with the embed, I also had to install the Google Cast extension in my browser.

The normally used load command will work if you specify the object_pairs_hook parameter:

import json
from  collections import OrderedDict
with open('foo.json', 'r') as fp:
    metrics_types = json.load(fp, object_pairs_hook=OrderedDict)

A good way to check whether a python object is an instance of a type is to use isinstance() which is Python's 'built-in' function. For Python 3.6:

dct = {
       "1": "a", 
       "3": "b", 
       "8": {
            "12": "c", 
            "25": "d"
           }
      }

for key in dct.keys():
    if isinstance(dct[key], dict)== False:
       print(key, dct[key])
#shows:
# 1 a
# 3 b

create table myTable 
(
    Column1 int not null,
    Column2 int not null
)
GO


ALTER TABLE myTable
    ADD  PRIMARY KEY (Column1,Column2)
GO

In Java, 2D arrays are really arrays of arrays with possibly different lengths (there are no guarantees that in 2D arrays that the 2nd dimension arrays all be the same length)

You can get the length of any 2nd dimension array as z[n].length where 0 <= n < z.length.

If you're treating your 2D array as a matrix, you can simply get z.length and z[0].length, but note that you might be making an assumption that for each array in the 2nd dimension that the length is the same (for some programs this might be a reasonable assumption).

YUI has a testing framework as well. This video from Yahoo! Theater is a nice introduction, although there are a lot of basics about TDD up front.

This framework is generic and can be run against any JavaScript or JS library.

You can have only one public class in a file else you will get the error what you are getting now and name of file must be the name of public class

I have two solutions for this Question.

1. The first solution is on getting display names from enum.

public enum CourseLocationTypes
{
    [Display(Name = "On Campus")]
    OnCampus,
    [Display(Name = "Online")]
    Online,
    [Display(Name = "Both")]
    Both
}

public static string DisplayName(this Enum value)
{
    Type enumType = value.GetType();
    string enumValue = Enum.GetName(enumType, value);
    MemberInfo member = enumType.GetMember(enumValue)[0];

    object[] attrs = member.GetCustomAttributes(typeof(DisplayAttribute), false);
    string outString = ((DisplayAttribute)attrs[0]).Name;

    if (((DisplayAttribute)attrs[0]).ResourceType != null)
    {
        outString = ((DisplayAttribute)attrs[0]).GetName();
    }

    return outString;
}

<h3 class="product-title white">@Model.CourseLocationType.DisplayName()</h3>

2. The second Solution is on getting display name from enum name but that will be enum split in developer language it's called patch.

public static string SplitOnCapitals(this string text)
{
        var r = new Regex(@"
            (?<=[A-Z])(?=[A-Z][a-z]) |
             (?<=[^A-Z])(?=[A-Z]) |
             (?<=[A-Za-z])(?=[^A-Za-z])", RegexOptions.IgnorePatternWhitespace);

        return r.Replace(text, " ");
}

 <div class="widget-box pt-0">
     @foreach (var item in Enum.GetNames(typeof(CourseLocationType)))
     {
         <label class="pr-2 pt-1">
             @Html.RadioButtonFor(x => x.CourseLocationType, item, new { type = "radio", @class = "iCheckBox control-label" })&nbsp; @item.SplitOnCapitals()
         </label>
     }
     @Html.ValidationMessageFor(x => x.CourseLocationType)
 </div>

I've investigated A LOT on how to properly manage 404s in MVC (specifically MVC3), and this, IMHO is the best solution I've come up with:

In global.asax:

public class MvcApplication : HttpApplication
{
    protected void Application_EndRequest()
    {
        if (Context.Response.StatusCode == 404)
        {
            Response.Clear();

            var rd = new RouteData();
            rd.DataTokens["area"] = "AreaName"; // In case controller is in another area
            rd.Values["controller"] = "Errors";
            rd.Values["action"] = "NotFound";

            IController c = new ErrorsController();
            c.Execute(new RequestContext(new HttpContextWrapper(Context), rd));
        }
    }
}

ErrorsController:

public sealed class ErrorsController : Controller
{
    public ActionResult NotFound()
    {
        ActionResult result;

        object model = Request.Url.PathAndQuery;

        if (!Request.IsAjaxRequest())
            result = View(model);
        else
            result = PartialView("_NotFound", model);

        return result;
    }
}

(Optional)

Explanation:

AFAIK, there are 6 different cases that an ASP.NET MVC3 apps can generate 404s.

(Automatically generated by ASP.NET Framework:)

(1) An URL does not find a match in the route table.

(Automatically generated by ASP.NET MVC Framework:)

(2) An URL finds a match in the route table, but specifies a non-existent controller.

(3) An URL finds a match in the route table, but specifies a non-existant action.

(Manually generated:)

(4) An action returns an HttpNotFoundResult by using the method HttpNotFound().

(5) An action throws an HttpException with the status code 404.

(6) An actions manually modifies the Response.StatusCode property to 404.

Normally, you want to accomplish 3 objectives:

(1) Show a custom 404 error page to the user.

(2) Maintain the 404 status code on the client response (specially important for SEO).

(3) Send the response directly, without involving a 302 redirection.

There are various ways to try to accomplish this:

(1)

<system.web>
    <customErrors mode="On">
        <error statusCode="404" redirect="~/Errors/NotFound"/>
    </customError>
</system.web>

Problems with this solution:

1. Does not comply with objective (1) in cases (1), (4), (6).
2. Does not comply with objective (2) automatically. It must be programmed manually.
3. Does not comply with objective (3).

(2)

<system.webServer>
    <httpErrors errorMode="Custom">
        <remove statusCode="404"/>
        <error statusCode="404" path="App/Errors/NotFound" responseMode="ExecuteURL"/>
    </httpErrors>
</system.webServer>

Problems with this solution:

1. Only works on IIS 7+.
2. Does not comply with objective (1) in cases (2), (3), (5).
3. Does not comply with objective (2) automatically. It must be programmed manually.

(3)

<system.webServer>
    <httpErrors errorMode="Custom" existingResponse="Replace">
        <remove statusCode="404"/>
        <error statusCode="404" path="App/Errors/NotFound" responseMode="ExecuteURL"/>
    </httpErrors>
</system.webServer>

Problems with this solution:

1. Only works on IIS 7+.
2. Does not comply with objective (2) automatically. It must be programmed manually.
3. It obscures application level http exceptions. E.g. can't use customErrors section, System.Web.Mvc.HandleErrorAttribute, etc. It can't only show generic error pages.

(4)

<system.web>
    <customErrors mode="On">
        <error statusCode="404" redirect="~/Errors/NotFound"/>
    </customError>
</system.web>

and

<system.webServer>
    <httpErrors errorMode="Custom">
        <remove statusCode="404"/>
        <error statusCode="404" path="App/Errors/NotFound" responseMode="ExecuteURL"/>
    </httpErrors>
</system.webServer>

Problems with this solution:

1. Only works on IIS 7+.
2. Does not comply with objective (2) automatically. It must be programmed manually.
3. Does not comply with objective (3) in cases (2), (3), (5).

People that have troubled with this before even tried to create their own libraries (see http://aboutcode.net/2011/02/26/handling-not-found-with-asp-net-mvc3.html). But the previous solution seems to cover all the cases without the complexity of using an external library.

Try this code:

<?php
$path = '/var/www/html/project/somefolder';

$dirs = array();

// directory handle
$dir = dir($path);

while (false !== ($entry = $dir->read())) {
    if ($entry != '.' && $entry != '..') {
       if (is_dir($path . '/' .$entry)) {
            $dirs[] = $entry; 
       }
    }
}

echo "<pre>"; print_r($dirs); exit;

you can also pass the parameters through the command line. Command line arguments are stores in the array ARGV. so ARGV[0] is the first number and ARGV[1] the second number

#!/usr/bin/ruby

first_number = ARGV[0].to_i
second_number = ARGV[1].to_i

puts first_number + second_number

and you call it like this

% ./plus.rb 5 6
==> 11

This way you only need to free the structure because the fields are arrays with static sizes which will be allocated as part of the structure. This is also the reason that the addresses you see match: the array is the first thing in that structure. If you declared the fields as char * you would have to manually malloc and free them as well.

Some Oracle Products support publishing maven artifacts to a local repository. The products have a plugin/maven directory which contains descriptions where to find those artifacts and where to store them. There is a Plugin from Oracle which will actually do the upload.

See: http://docs.oracle.com/middleware/1212/core/MAVEN/config_maven.htm

One of the products which may ship OJDBC in this way is the WLS, it uses however quite strange coordinates:

<groupId>com.oracle.weblogic</groupId>
<artifactId>ojdbc6</artifactId>
<version>12.1.2-0-0</version>

Take a look at https://www.json.org

[edited] Imagine that you have a simple Java class like this:

public class Person {

    private String name;
    private Integer age;

    public String getName() { return this.name; }
    public void setName( String name ) { this.name = name; }

    public Integer getAge() { return this.age; }
    public void setAge( Integer age ) { this.age = age; }

}

So, to transform it to a JSon object, it's very simple. Like this:

import org.json.JSONObject;

public class JsonTest {

    public static void main( String[] args ) {
        Person person = new Person();
        person.setName( "Person Name" );
        person.setAge( 333 );

        JSONObject jsonObj = new JSONObject( person );
        System.out.println( jsonObj );
    }

}

Hope it helps.

[edited] Here there is other example, in this case using Jackson: https://brunozambiazi.wordpress.com/2015/08/15/working-with-json-in-java/

Maven:

<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-databind</artifactId>
    <version>2.6.1</version>
</dependency>

And a link (below) to find the latest/greatest version:

https://search.maven.org/classic/#search%7Cga%7C1%7Cg%3A%22com.fasterxml.jackson.core%22%20AND%20a%3A%22jackson-databind%22

If you want to match starting from the beginning of the word, use:

\b\w{3,}

\b: word boundary

\w: word character

{3,}: three or more times for the word character

egrep -o '^[^:]*:'

There are few modes to open file (read, write etc..)

If you want to read from file you should type file = open("File.txt","r"), if write than file = open("File.txt","w"). You need to give the right permission regarding your usage.

more modes:

• r. Opens a file for reading only.
• rb. Opens a file for reading only in binary format.
• r+ Opens a file for both reading and writing.
• rb+ Opens a file for both reading and writing in binary format.
• w. Opens a file for writing only.
• you can find more modes in here

How about:

SELECT * FROM sometable WHERE CHAR_LENGTH(LINK) > 1

Here's the MySql string functions page (5.0).

Note that I chose CHAR_LENGTH instead of LENGTH, as if there are multibyte characters in the data you're probably really interested in how many characters there are, not how many bytes of storage they take. So for the above, a row where LINK is a single two-byte character wouldn't be returned - whereas it would when using LENGTH.

Note that if LINK is NULL, the result of CHAR_LENGTH(LINK) will be NULL as well, so the row won't match.

Try browse the WCF in IIS see if it's alive and works normally,

In my case it's because the physical path of the WCF is misdirected.

What I have observed is: if you use openssl to generate certificates, it captures both the text part and the base64 certificate part in the crt file. The strict pem format says (wiki definition) that the file should start and end with BEGIN and END.

.pem – (Privacy Enhanced Mail) Base64 encoded DER certificate, enclosed between "-----BEGIN CERTIFICATE-----" and "-----END CERTIFICATE-----"

So for some libraries (I encountered this in java) that expect strict pem format, the generated crt would fail the validation as an 'invalid pem format'.

Even if you copy or grep the lines with BEGIN/END CERTIFICATE, and paste it in a cert.pem file, it should work.

Here is what I do, not very clean, but works for me, basically it filters the text starting from BEGIN line:

grep -A 1000 BEGIN cert.crt > cert.pem

I think IE dev tools (F12) has; View > Source > DOM (Page)

You would need to copy and paste the DOM and save it to send to the validator.

A solution in Java 8:

Date startOfToday = Date.from(ZonedDateTime.now().with(LocalTime.MIN).toInstant());

Check this may be helpful. Works fine for me. Code also covered daylight savings

    TimeZone tz = TimeZone.getTimeZone("Asia/Shanghai");
    Calendar cal = Calendar.getInstance();      
    // If needed in hours rather than milliseconds
    int LocalOffSethrs = (int) ((cal.getTimeZone().getRawOffset()) *(2.77777778 /10000000));        
    int ChinaOffSethrs = (int) ((tz.getRawOffset()) *(2.77777778 /10000000));       
    int dts = cal.getTimeZone().getDSTSavings();
    System.out.println("Local Time Zone : " + cal.getTimeZone().getDisplayName());
    System.out.println("Local Day Light Time Saving : " + dts);

For windows, I made composer.cmd and used the below text:

php c:\programs\php\composer.phar %*

where composer.phar is installed and c:\programs\php\ is added to my path.

Not sure why this isn't done automatically.

if you want to reload your entire page, like it seems, just inject $window into your controller and then call

$window.location.href = '/';

but if you only want to reload your current view, inject $scope, $state and $stateParams (the latter just in case you need to have some parameters change in this upcoming reload, something like your page number), then call this within any controller method:

$stateParams.page = 1;
$state.reload();

Yes, I couldn't see how to use 'default' in the migration generator command either but was able to specify a default value for a new string column as follows by amending the generated migration file before applying "rake db:migrate":

class AddColumnToWidgets < ActiveRecord::Migration
  def change
    add_column :widgets, :colour, :string, default: 'red'
  end
end

This adds a new column called 'colour' to my 'Widget' model and sets the default 'colour' of new widgets to 'red'.

I had same error and the mistake was that I had added list and dictionary into the same list (object) and when I used to iterate over the list of dictionaries and use to hit a list (type) object then I used to get this error.

Its was a code error and made sure that I only added dictionary objects to that list and list typed object into the list, this solved my issue as well.

#include<iostream>
#include<vector>
#include<string>
using namespace std;
int main()
{
    vector<string>V;
    int num;
    cin>>num;
    string input;
    while (cin>>input && num != 0) //enter any non-integer to end the loop!
{
    //cin>>input;
   V.push_back(input);
   num--;
   if(num==0)
   {
   vector<string>::iterator it;
    for(it=V.begin();it!=V.end();it++)
        cout<<*it<<endl;
   };

}
return 0;

};

we can enable CORS in the frontend by using the ngResourse module. But most importantly, we should have this piece of code while making the ajax request in the controller,

$scope.weatherAPI = $resource(YOUR API,
     {callback: "JSON_CALLBACK"}, {get: {method: 'JSONP'}});
 $scope.weatherResult = $scope.weatherAPI.get(YOUR REQUEST DATA, if any);

Also, you must add ngResourse CDN in the script part and add as a dependency in the app module.

<script src="https://code.angularjs.org/1.2.16/angular-resource.js"></script>

Then use "ngResourse" in the app module dependency section

var routerApp = angular.module("routerApp", ["ui.router", 'ngResource']);

I got the same error in this case:

var result = Db.SystemLog
.Where(log =>
    eventTypeValues.Contains(log.EventType)
    && (
        search.Contains(log.Id.ToString())
        || log.Message.Contains(search)
        || log.PayLoad.Contains(search)
        || log.Timestamp.ToString(CultureInfo.CurrentUICulture).Contains(search)
    )
)
.OrderByDescending(log => log.Id)
.Select(r => r);

After spending way too much time debugging, I figured out that error appeared in the logic expression.

The first line search.Contains(log.Id.ToString()) does work fine, but the last line that deals with a DateTime object made it fail miserably:

|| log.Timestamp.ToString(CultureInfo.CurrentUICulture).Contains(search)

Remove the problematic line and problem solved.

I do not fully understand why, but it seems as ToString() is a LINQ expression for strings, but not for Entities. LINQ for Entities deals with database queries like SQL, and SQL has no notion of ToString(). As such, we can not throw ToString() into a .Where() clause.

But how then does the first line work? Instead of ToString(), SQL have CAST and CONVERT, so my best guess so far is that linq for entities uses that in some simple cases. DateTime objects are not always found to be so simple...

You have the syntax wrong; there is no need to place a period inside a double-quoted string. Instead, it should be more like

$query = mysql_query("SELECT * FROM table WHERE the_number LIKE '$prefix%'");

You can confirm this by printing out the string to see that it turns out identical to the first case.

Of course it's not a good idea to simply inject variables into the query string like this because of the danger of SQL injection. At the very least you should manually escape the contents of the variable with mysql_real_escape_string, which would make it look perhaps like this:

$sql = sprintf("SELECT * FROM table WHERE the_number LIKE '%s%%'",
               mysql_real_escape_string($prefix));
$query = mysql_query($sql);

Note that inside the first argument of sprintf the percent sign needs to be doubled to end up appearing once in the result.

I was able to get jsPDF to print dynamically created tables from a div.

$(document).ready(function() {

        $("#pdfDiv").click(function() {

    var pdf = new jsPDF('p','pt','letter');
    var specialElementHandlers = {
    '#rentalListCan': function (element, renderer) {
        return true;
        }
    };

    pdf.addHTML($('#rentalListCan').first(), function() {
        pdf.save("caravan.pdf");
    });
    });
});

Works great with Chrome and Firefox... formatting is all blown up in IE.

You could give it a try. The problem is that Windows inserts a carriage return as well as a line feed when given a new line. Unix-systems just insert a line feed. So the extra carriage return character could be the reason why your eclipse messes up with the newlines.

Grab one or two files from your project and convert them. You could use Notepad++ to do so. Just open the file, go to Format->Convert to Unix (when you are using windows).

In Linux just try this on a command line:

sed 's/$'"/`echo \\\r`/" yourfile.java > output.java

To answer the non-reproducability aspect of the question - Firefox automatically imports intermediate certificates into its certificate store. So if you've previously visited a site which has used the same Intermediate Certificate using a correctly configured certificate chain then Firefox will store that Certificate so you will not see the problem when you visit a site that has an incorrectly configured chain using the same Intermediate certificate.

You can check this in Firefox's Certificate Manager (Options->Privacy&Security->View Certificates...) where you can see all stored certificates. Under the 'Security Device' Column you can check where a certificate has come from - automatically/manually imported certificates will appear as from 'Software Security Device' as opposed to the 'Builtin Object Token', which are the default set installed with Firefox. You can delete/Distrust any specific certificates and test again.

Some of these answers do work, but setting position: absolute; and z-index: 10; seemed pretty strong just to achieve the required effect. I found the following was all that was required, though unfortunately, I've not been able to reduce it any further.

HTML:

<div class="wrapper">
    <div class="parent">
        <div class="child">
            ...
        </div>
    </div>
</div>

CSS:

.wrapper {
    position: relative;
    z-index: 0;
}

.child {
    position: relative;
    z-index: -1;
}

I used this technique to achieve a bordered hover effect for image links. There's a bit more code here but it uses the concept above to show the border over the top of the image.

If you are like me using a TFT that is connected via SPI (e. g. PiTFT 2.8" 320x240) driven by FBTFT in combination with fbcp to utilise hardware accelerated video decoding (using omxplayer) like it is descriped here. You should add the following into the /boot/config.txt to force the output to HDMI and set the resolution to 320x240:

hdmi_force_hotplug=1
hdmi_cvt=320 240 60 1 0 0 0
hdmi_group=2
hdmi_mode=87

background: rgba(0,0,0,.5);

you can use rgba for opacity, will only work in ie9+ and better browsers

Here is creating a ComboBox adding a listener for item selection change:

JComboBox comboBox = new JComboBox();

comboBox.setBounds(84, 45, 150, 20);
contentPane.add(comboBox);

JComboBox comboBox_1 = new JComboBox();
comboBox_1.setBounds(84, 97, 150, 20);
contentPane.add(comboBox_1);
comboBox.addItemListener(new ItemListener() {
    public void itemStateChanged(ItemEvent arg0) {
        //Do Something
    }
});

Just in case anyone is having the same problem... I was getting this error, and it turned out to be my <Application.Resources> in my App.xaml file. I had a resource outside my resource dictionary tags, and that caused this error.

Multiply the input by Math.PI/180 to convert from degrees to radians before calling the system trig functions.

You could also define your own functions:

function sinDegrees(angleDegrees) {
    return Math.sin(angleDegrees*Math.PI/180);
};

and so on.

Here is an end to end solution I implemented for streaming Android microphone audio to a server for playback: Android AudioRecord to Server over UDP Playback Issues

It's the special table in Oracle. I often use it for calculations or checking system variables. For example:

• Select 2*4 from dual prints out the result of the calculation
• Select sysdate from dual prints the server current date.

The expression -z string is true if the length of string is zero.

One possibility is that the target .NET Framework version of the class library is higher than that of the project.

Thank you for your help. Just in case if people are still having problems, try this.

For MySQL version 5.6 and under

Have you forgotten your Mac OS X 'ROOT' password  and need to reset it?  Follow these 4 simple steps:

1.  Stop the mysqld server.  Typically this can be done by from 'System Prefrences' > MySQL > 'Stop MySQL Server'
2.  Start the server in safe mode with privilege bypass      From a terminal:      sudo /usr/local/mysql/bin/mysqld_safe --skip-grant-tables
3.  In a new terminal window:      sudo /usr/local/mysql/bin/mysql -u root      UPDATE mysql.user SET Password=PASSWORD('NewPassword') WHERE User='root';      FLUSH PRIVILEGES;      \q
4.  Stop the mysqld server again and restart it in normal mode.

For MySQL version 5.7 and up

1.  Stop the mysqld server.  Typically this can be done by from 'System Prefrences' > MySQL > 'Stop MySQL Server'
2.  Start the server in safe mode with privilege bypass      From a terminal:      sudo /usr/local/mysql/bin/mysqld_safe --skip-grant-tables
3.  In a new terminal window:            sudo /usr/local/mysql/bin/mysql -u root      UPDATE mysql.user SET authentication_string=PASSWORD('NewPassword') WHERE User='root';      FLUSH PRIVILEGES;      \q      
4.  Stop the mysqld server again and restart it in normal mode.

SELECT LTRIM(RTRIM(Replace(Replace(Replace(name,'   ',' '),CHAR(13), ' '),char(10), ' ')))
from author

late to the party. but if you only want to get rid of leading/trailing white space, R base has a function trimws

For example:

data <- apply(X = data, MARGIN = 2, FUN = trimws) %>% as.data.frame()

Here's one way in XSLT 2

<?xml version="1.0" encoding="UTF-8"?> <xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">   <xsl:template match="@*|node()">     <xsl:copy>       <xsl:apply-templates select="@*|node()"/>     </xsl:copy>   </xsl:template>   <xsl:template match="text()">     <xsl:value-of select="translate(.,'&quot;','''')"/>   </xsl:template> </xsl:stylesheet> 

Doing it in XSLT1 is a little more problematic as it's hard to get a literal containing a single apostrophe, so you have to resort to a variable:

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">   <xsl:template match="@*|node()">     <xsl:copy>       <xsl:apply-templates select="@*|node()"/>     </xsl:copy>   </xsl:template>   <xsl:variable name="apos">'</xsl:variable>   <xsl:template match="text()">     <xsl:value-of select="translate(.,'&quot;',$apos)"/>   </xsl:template> </xsl:stylesheet> 

You can change the button color by applying a tint color to an UIAlertController.

On iOS 9, if the window tint color was set to a custom color, you have to apply the tint color right after presenting the alert. Otherwise the tint color will be reset to your custom window tint color.

// In your AppDelegate for example:
window?.tintColor = UIColor.redColor()

// Elsewhere in the App:
let alertVC = UIAlertController(title: "Title", message: "message", preferredStyle: .Alert)
alertVC.addAction(UIAlertAction(title: "Cancel", style: .Cancel, handler: nil))
alertVC.addAction(UIAlertAction(title: "Ok", style: .Default, handler: nil))

// Works on iOS 8, but not on iOS 9
// On iOS 9 the button color will be red
alertVC.view.tintColor = UIColor.greenColor()

self.presentViewController(alert, animated: true, completion: nil)

// Necessary to apply tint on iOS 9
alertVC.view.tintColor = UIColor.greenColor()

You still need to set callback in the params:

var params = {
  'a': b,
  'token_auth': TOKEN,
  'callback': 'functionName'
};
$sce.trustAsResourceUrl(url);

$http.jsonp(url, {
  params: params
});

Where 'functionName' is a stringified reference to globally defined function. You can define it outside of your angular script and then redefine it in your module.

I would like to share a great tool being used in the WordPress community called Scatter

Git WordPress plugins and a bit of sanity scatter

This enables users to be able to send their Git repository to wordpress.org SVN automatically. In theory, this code can be applied to any SVN repository.

var result = from cx in CustomerList
         group cx by cx.GroupID into cxGroup
     orderby cxGroup.Key
     select cxGroup; 

foreach (var cxGroup in result) { 
Console.WriteLine(String.Format("GroupID = {0}", cxGroup.Key)); 
  foreach (var cx in cxGroup) { 
    Console.WriteLine(String.Format("\tUserID = {0}, UserName = {1}, GroupID = {2}", 
      new object[] { cx.ID, cx.Name, cx.GroupID })); 
  }
}

TRY THIS

SELECT E.ename,E.empno,ISNULL(E.ename,'NO MANAGER') AS MANAGER FROM emp e
INNER JOIN emp M
ON  M.empno=E.empno

under windows 10 one can use VT100 style by activating the VT100 mode in the current console to use escape sequences as follow :

#include <windows.h>
#include <iostream>

#define ENABLE_VIRTUAL_TERMINAL_PROCESSING 0x0004
#define DISABLE_NEWLINE_AUTO_RETURN  0x0008

int main(){

  // enabling VT100 style in current console
  DWORD l_mode;
  HANDLE hStdout = GetStdHandle(STD_OUTPUT_HANDLE);
  GetConsoleMode(hStdout,&l_mode)
  SetConsoleMode( hStdout, l_mode |
            ENABLE_VIRTUAL_TERMINAL_PROCESSING |
            DISABLE_NEWLINE_AUTO_RETURN );

  // create a waiting loop with changing text every seconds
  while(true) {
    // erase current line and go to line begining 
    std::cout << "\x1B[2K\r";
    std::cout << "wait a second .";
    Sleep(1);
    std::cout << "\x1B[2K\r";
    std::cout << "wait a second ..";
    Sleep(1);
    std::cout << "\x1B[2K\r";
    std::cout << "wait a second ...";
    Sleep(1);
    std::cout << "\x1B[2K\r";
    std::cout << "wait a second ....";
 }

}

If your experiencing the same problem while querying a DB2 database, you'll need to use the below query.

I ran into an article that illustrates a method where the data from the same excel sheet can be imported in the selected table until there is no modifications in excel with data types.

If the data is inserted or overwritten with new ones, importing process will be successfully accomplished, and the data will be added to the table in SQL database.

The article may be found here: http://www.sqlshack.com/using-ssis-packages-import-ms-excel-data-database/

Hope it helps.

For anyone having this problem today, the solution is simply:

list-style: "- "

cout << "Enter amount of spaces you would like (integer)" << endl; 
cin >> n;
//print n spaces
for (int i = 0; i < n; ++i)
{
   cout << " " ;
}
cout <<endl;

It looks like XMLHttpRequest has been replaced by the Fetch API. Google published a good introduction that includes this example doing what you want:

fetch('./api/some.json')
  .then(
    function(response) {
      if (response.status !== 200) {
        console.log('Looks like there was a problem. Status Code: ' +
          response.status);
        return;
      }

      // Examine the text in the response
      response.json().then(function(data) {
        console.log(data);
      });
    }
  )
  .catch(function(err) {
    console.log('Fetch Error :-S', err);
  });

However, you probably want to call response.text() instead of response.json().

Activate MySQL general.log (disk intensive) and use mysql_analyse_general_log.pl to extract long running transactions, for example with :

--min-duration=your innodb_lock_wait_timeout value

Disable general.log after that.
