adding log4j-1.2.12.jar file has resolved the issue for me

you can't. foo-bar is not an identifier. rename the file to foo_bar.py

Edit: If import is not your goal (as in: you don't care what happens with sys.modules, you don't need it to import itself), just getting all of the file's globals into your own scope, you can use execfile

# contents of foo-bar.py
baz = 'quux'

>>> execfile('foo-bar.py')
>>> baz
'quux'
>>> 

In SQL you can not have a variable array.
However, the best alternative solution is to use a temporary table.

String input = "2,1,3,4,5,10,100";
String[] strings = input.split(",");
int[] numbers = new int[strings.length];
for (int i = 0; i < numbers.length; i++)
{
  numbers[i] = Integer.parseInt(strings[i]);
}
Arrays.sort(numbers);

System.out.println(Arrays.toString(numbers));

Assuming that the above step is completed and MySql port 3306 is free to be accessed remotely; Don't forget to bind the public ip address in the mysql config file.

For example on my ubuntu server:

#nano /etc/mysql/my.cnf

In the file, search for the [mysqld] section block and add the new bind address, in this example it is 192.168.0.116. It would look something like this

......    
.....    
# Instead of skip-networking the default is now to listen only on
# localhost which is more compatible and is not less secure.

bind-address        = 127.0.0.1    
bind-address        = 192.168.0.116

.....    
......

you can remove th localhost(127.0.0.1) binding if you choose, but then you have to specifically give an IP address to access the server on the local machine.

Then the last step is to restart the MySql server (on ubuntu)

stop mysql

start mysql

or #/etc/init.d/mysql restart for other systems

Now the MySQL database can be accessed remotely by:

mysql -u username -h 192.168.0.116 -p

The fact of the matter is that products such as Entity Framework will ALWAYS be slow and inefficient, because they are executing lot more code.

I also find it silly that people are suggesting that one should optimize LINQ queries, look at the SQL generated, use debuggers, pre-compile, take many extra steps, etc. i.e. waste a lot of time. No one says - Simplify! Everyone wants to comlicate things further by taking even more steps (wasting time).

A common sense approach would be not to use EF or LINQ at all. Use plain SQL. There is nothing wrong with it. Just because there is herd mentality among programmers and they feel the urge to use every single new product out there, does not mean that it is good or it will work. Most programmers think if they incorporate every new piece of code released by a large company, it is making them a smarter programmer; not true at all. Smart programming is mostly about how to do more with less headaches, uncertainties, and in the least amount of time. Remember - Time! That is the most important element, so try to find ways not to waste it on solving problems in bad/bloated code written simply to conform with some strange so called 'patterns'

Relax, enjoy life, take a break from coding and stop using extra features, code, products, 'patterns'. Life is short and the life of your code is even shorter, and it is certainly not rocket science. Remove layers such as LINQ, EF and others, and your code will run efficiently, will scale, and yes, it will still be easy to maintain. Too much abstraction is a bad 'pattern'.

And that is the solution to your problem.

You can force browsers to cache something, but

You can't force browsers to clear their cache.

Thus the only (AMAIK) way is to use a new URL for your resources. Something like versioning.

Note: Why am I providing yet another answer? This answer is based on the title of the question and the notion that camelcase is defined as: a series of words that have been concatenated (no spaces!) such that each of the original words start with a capital letter (the rest being lowercase) excepting the first word of the series (which is completely lowercase). Also it is assumed that "all strings" refers to ASCII character set; unicode would not work with this solution).

simple

Given the above definition, this function

import re
word_regex_pattern = re.compile("[^A-Za-z]+")

def camel(chars):
  words = word_regex_pattern.split(chars)
  return "".join(w.lower() if i is 0 else w.title() for i, w in enumerate(words))

, when called, would result in this manner

camel("San Francisco")  # sanFrancisco
camel("SAN-FRANCISCO")  # sanFrancisco
camel("san_francisco")  # sanFrancisco

less simple

Note that it fails when presented with an already camel cased string!

camel("sanFrancisco")   # sanfrancisco  <-- noted limitation

even less simple

Note that it fails with many unicode strings

camel("México City")    # mXicoCity     <-- can't handle unicode

I don't have a solution for these cases(or other ones that could be introduced with some creativity). So, as in all things that have to do with strings, cover your own edge cases and good luck with unicode!

If you are only saving a single object (your data frame), you could also use saveRDS.
To save:

saveRDS(foo, file="data.Rda")

Then read it with:

bar <- readRDS(file="data.Rda")

The difference between saveRDS and save is that in the former only one object can be saved and the name of the object is not forced to be the same after you load it.

You can use context syntax with this or $(this). This is the same effect as find().

$('select').change(function() {_x000D_
    console.log('Clicked option value => ' + $(this).val());_x000D_
    <!-- undefined console.log('$(this) without explicit :select => ' + $(this).data('id')); -->_x000D_
    <!-- error console.log('this without explicit :select => ' + this.data('id')); -->_x000D_
    console.log(':select & $(this) =>    ' + $(':selected', $(this)).data('id'));_x000D_
    console.log(':select & this =>       ' + $(':selected', this).data('id'));_x000D_
    console.log('option:select & this => ' + $('option:selected', this).data('id'));_x000D_
    console.log('$(this) & find =>       ' + $(this).find(':selected').data('id'));_x000D_
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<select>_x000D_
    <option data-id="1">one</option>_x000D_
    <option data-id="2">two</option>_x000D_
    <option data-id="3">three</option>_x000D_
</select>

As a matter of microoptimization, you might opt for find(). If you are more of a code golfer, the context syntax is more brief. It comes down to coding style basically.

Here is a relevant performance comparison.

Here's a project with a rotating camera. Looking through the source it seems to just move the camera position in a circle.

function onDocumentMouseMove( event ) {

    event.preventDefault();

    if ( isMouseDown ) {

        theta = - ( ( event.clientX - onMouseDownPosition.x ) * 0.5 )
                + onMouseDownTheta;
        phi = ( ( event.clientY - onMouseDownPosition.y ) * 0.5 )
              + onMouseDownPhi;

        phi = Math.min( 180, Math.max( 0, phi ) );

        camera.position.x = radious * Math.sin( theta * Math.PI / 360 )
                            * Math.cos( phi * Math.PI / 360 );
        camera.position.y = radious * Math.sin( phi * Math.PI / 360 );
        camera.position.z = radious * Math.cos( theta * Math.PI / 360 )
                            * Math.cos( phi * Math.PI / 360 );
        camera.updateMatrix();

    }

    mouse3D = projector.unprojectVector(
        new THREE.Vector3(
            ( event.clientX / renderer.domElement.width ) * 2 - 1,
            - ( event.clientY / renderer.domElement.height ) * 2 + 1,
            0.5
        ),
        camera
    );
    ray.direction = mouse3D.subSelf( camera.position ).normalize();

    interact();
    render();

}

Here's another demo and in this one I think it just creates a new THREE.TrackballControls object with the camera as a parameter, which is probably the better way to go.

controls = new THREE.TrackballControls( camera );
controls.target.set( 0, 0, 0 )

use this : export MYVAR="$(dirname "$(dirname "$(dirname "$(dirname $PWD)")")")" if you want 4th parent directory

export MYVAR="$(dirname "$(dirname "$(dirname $PWD)")")" if you want 3rd parent directory

export MYVAR="$(dirname "$(dirname $PWD)")" if you want 2nd parent directory

In the other hand, there is some packages in AngularJS which are helpful (in AJAX WEB):

A simple way is to use python. in python terminal type

r"C:\Users\surfcat\Desktop\2006_dissimilarity.csv" and you'll get back 'C:\Users\surfcat\Desktop\2006_dissimilarity.csv'

Per the Javadoc:

Returns the value of a request parameter as a String, or null if the parameter does not exist.

Do note that it is possible to submit an empty parameter - such that the parameter exists, but has no value. For example, I could include &log=&somethingElse into the URL to enable logging, without needing to specify &log=true. In this case, the value will be an empty String ("").

d = dict()

or

d = {}

or

import types
d = types.DictType.__new__(types.DictType, (), {})

Go to your Jenkins server's front page, click on REST API at the bottom of the page:

Create Job

To create a new job, post config.xml to this URL with query parameter name=JOBNAME. You need to send a Content-Type: application/xml header. You'll get 200 status code if the creation is successful, or 4xx/5xx code if it fails. config.xml is the format Jenkins uses to store the project in the file system, so you can see examples of them in the Jenkins home directory, or by retrieving the XML configuration of existing jobs from /job/JOBNAME/config.xml.

You should be able to set these via the attr() or prop() functions in jQuery as shown below:

jQuery (< 1.7):

// This will disable just the div
$("#dcacl").attr('disabled','disabled');

or

// This will disable everything contained in the div
$("#dcacl").children().attr("disabled","disabled");

jQuery (>= 1.7):

// This will disable just the div
$("#dcacl").prop('disabled',true);

or

// This will disable everything contained in the div
$("#dcacl").children().prop('disabled',true);

or

//  disable ALL descendants of the DIV
$("#dcacl *").prop('disabled',true);

Javascript:

// This will disable just the div
document.getElementById("dcalc").disabled = true;

or

// This will disable all the children of the div
var nodes = document.getElementById("dcalc").getElementsByTagName('*');
for(var i = 0; i < nodes.length; i++){
     nodes[i].disabled = true;
}

The Chromatable jquery plugin allows a fixed header (or top row) with widths that allow percentages--granted, only a percentage of 100%.

http://www.chromaloop.com/posts/chromatable-jquery-plugin

I can't think of how you could do this without javascript.

You have to define your exception elsewhere as a new class

public class YourCustomException extends Exception{

//Required inherited methods here
}

Then you can throw and catch YourCustomException as much as you'd like.

Invoke-Sqlcmd -Query "sp_who" -ServerInstance . -QueryTimeout 3

$(document).ready(function () {
    $(document).on('change', 'input[Id="chkproperty"]', function (e) {
        alert($(this).val());
    });
});

-> Go to pom.xml

-> Add this Dependency :

You can call Stored Procedure like this inside Stored Procedure B.

CREATE PROCEDURE spA

    EXEC spB @myDate

   return[list(elemento)[::-1] for elemento in ruota][::-1]

Let's say we want to print all numbers which are not multiples of 3 and 5

for x in range(0, 101):
    if x % 3 ==0 or x % 5 == 0:
        continue
        #no more code is executed, we go to the next number 
    print x

I'll start off my noting that this hasn't happened since I upgraded my RAM. I was at 4GB and would often have multiple instances of VS open along with SSMS. I have since gone to 8GB and then 16GB.

Here's the steps I go through when I lose intellisense.

If only one file/window appears to be affected, close/reopen that file. If that doesn't work, try below.

In Visual Studio:

1. Click Tools->Options->Text Editor->All Languages->General
2. Uncheck "Auto list members"
3. Uncheck "Parameter information"
4. Check "Auto list members" (yes, the one you just unchecked)
5. Check "Parameter information" (again, the one you just unchecked)
6. Click OK

If this doesn't work, here's a few more steps to try:

1. Close all VS documents and reopen
2. If still not working, close/reopen solution
3. If still not working, restart VS.

For C++ projects:
MSDN has a few things to try: MSDN suggestions

The corrupt .ncb file seems most likely.

From MSDN:

1. Close the solution.
2. Delete the .ncb file.
3. Reopen the solution. (This creates a new .ncb file.)

Notes:

• This issue does not appear to be specific to C# as C++ and VB users report the same issue

• Tested in VS 2013/2015

first select the table you you would like to make the relation with >> then go to operation , for each table there is difference operation setting, >> inside operation "storage engine" choose innoDB option

innoDB will allow you to view the "relation view" which will help you make the foreign key

Try the following:

for i = 1:4
    result = strcat('f',int2str(i));
end

If you use this for naming several files that your code generates, you are able to concatenate more parts to the name. For example, with the extension at the end and address at the beginning:

filename = strcat('c:\...\name',int2str(i),'.png'); 

I solved the similar situation with basic technique using pandas. First load the csv or text file using pandas.It's pretty simple

data=pd.read_excel('link to the file')

Then set the index of data to the respected column that needs to be changed. For example, if your data has ID as one attribute or column, then set index to ID.

 data = data.set_index("ID")

Then delete all the rows with "id" as the value instead of number using following command.

  data = data.drop("id", axis=0). 

Hope, this will help you.

You need 10 ÷R 3 = 1 This will display both the reminder and the quoitent

The error you're getting appears to be the result of the fact that there is no underscore between "chartered" and "flight" in the table name. I assume you want something like this where the name of the table is chartered_flight.

CREATE TABLE chartered_flight(flight_no NUMBER(4) PRIMARY KEY
, customer_id NUMBER(6) REFERENCES customer(customer_id)
, aircraft_no NUMBER(4) REFERENCES aircraft(aircraft_no)
, flight_type VARCHAR2 (12)
, flight_date DATE NOT NULL
, flight_time INTERVAL DAY TO SECOND NOT NULL
, takeoff_at CHAR (3) NOT NULL
, destination CHAR (3) NOT NULL)

Generally, there is no benefit to declaring a column as CHAR(3) rather than VARCHAR2(3). Declaring a column as CHAR(3) doesn't force there to be three characters of (useful) data. It just tells Oracle to space-pad data with fewer than three characters to three characters. That is unlikely to be helpful if someone inadvertently enters an incorrect code. Potentially, you could declare the column as VARCHAR2(3) and then add a CHECK constraint that LENGTH(takeoff_at) = 3.

CREATE TABLE chartered_flight(flight_no NUMBER(4) PRIMARY KEY
, customer_id NUMBER(6) REFERENCES customer(customer_id)
, aircraft_no NUMBER(4) REFERENCES aircraft(aircraft_no)
, flight_type VARCHAR2 (12)
, flight_date DATE NOT NULL
, flight_time INTERVAL DAY TO SECOND NOT NULL
, takeoff_at CHAR (3) NOT NULL CHECK( length( takeoff_at ) = 3 )
, destination CHAR (3) NOT NULL CHECK( length( destination ) = 3 )
)

Since both takeoff_at and destination are airport codes, you really ought to have a separate table of valid airport codes and define foreign key constraints between the chartered_flight table and this new airport_code table. That ensures that only valid airport codes are added and makes it much easier in the future if an airport code changes.

And from a naming convention standpoint, since both takeoff_at and destination are airport codes, I would suggest that the names be complementary and indicate that fact. Something like departure_airport_code and arrival_airport_code, for example, would be much more meaningful.

pd.date_range('2019-01-01', '2019-02-01').shape[0]

for (var key in localStorage){
   console.log(key)
}

EDIT: this answer is getting a lot of upvotes, so I guess it's a common question. I feel like I owe it to anyone who might stumble on my answer and think that it's "right" just because it was accepted to make an update. Truth is, the example above isn't really the right way to do this. The best and safest way is to do it like this:

for ( var i = 0, len = localStorage.length; i < len; ++i ) {
  console.log( localStorage.getItem( localStorage.key( i ) ) );
}

Are you sure it is smaller?

Bitmap original = BitmapFactory.decodeStream(getAssets().open("1024x768.jpg"));
ByteArrayOutputStream out = new ByteArrayOutputStream();
original.compress(Bitmap.CompressFormat.PNG, 100, out);
Bitmap decoded = BitmapFactory.decodeStream(new ByteArrayInputStream(out.toByteArray()));

Log.e("Original   dimensions", original.getWidth()+" "+original.getHeight());
Log.e("Compressed dimensions", decoded.getWidth()+" "+decoded.getHeight());

Gives

12-07 17:43:36.333: E/Original   dimensions(278): 1024 768
12-07 17:43:36.333: E/Compressed dimensions(278): 1024 768

Maybe you get your bitmap from a resource, in which case the bitmap dimension will depend on the phone screen density

Bitmap bitmap=((BitmapDrawable)getResources().getDrawable(R.drawable.img_1024x768)).getBitmap();
Log.e("Dimensions", bitmap.getWidth()+" "+bitmap.getHeight());

12-07 17:43:38.733: E/Dimensions(278): 768 576

Just simply use isset($_POST['radio']) so that whenever i click any of the radio button, the one that is clicked is set to the post.

 <form method="post" action="sample.php">
 select sex: 
 <input type="radio" name="radio" value="male">
 <input type="radio" name="radio" value="female">

 <input type="submit" value="submit">
 </form>

<?php

if (isset($_POST['radio'])){

    $Sex = $_POST['radio'];
 }
  ?>

for(int i = 0; i < n; i++) {
    existing_string += 'c';
}

but you should use StringBuilder instead, and save memory

int n = 3;
String existing_string = "string";
StringBuilder builder = new StringBuilder(existing_string);
for (int i = 0; i < n; i++) {
    builder.append(" append ");
}

System.out.println(builder.toString());

You just have to replace the break with a return statement.

Think of the code inside the Foreach-Object as an anonymous function. If you have loops inside the function, just use the control keywords applying to the construction (continue, break, ...).

For me it was case of having two beans implementing the same interface. One was a fake ban for the sake of unit test which was conflicting with original bean. If we use

@component("suggestionServicefake")

, it still references with suggestionService. So I removed @component and only used

@Qualifier("suggestionServicefake")

which solved the problem

another workaround:

var myarray = [];
$("#test").click(function() {
    myarray[index]=$("#drop").val();
    alert(myarray);
});

i wanted to add all checked checkbox to array. so example, if .each is used:

var vpp = [];
var incr=0;
$('.prsn').each(function(idx) {
   if (this.checked) {
       var p=$('.pp').eq(idx).val();
       vpp[incr]=(p);
       incr++;
   }
});
//do what ever with vpp array;

Try to use this variant:

<?php echo Yii::app()->createAbsoluteUrl('your_yii_application/?lg=pl', array('id'=>$model->id));?>

It is the easiest way, I guess.

For me the following worked which is copied from example in /etc/apache2/apache2.conf:

<Directory /srv/www/default>
    Options Indexes FollowSymLinks
    AllowOverride None
    Require all granted
</Directory>

Require all granted option is the solution for the first problem example in wiki.apache.org page dedicated for this issue for Apache version 2.4+.

More details about Require option can be found on official apache page for mod_authz module and on this page too. Namely:

Require all granted -> Access is allowed unconditionally.

JavaScript, as defined in your question, can't directly work with MySql. This is because it isn't running on the same computer.

JavaScript runs on the client side (in the browser), and databases usually exist on the server side. You'll probably need to use an intermediate server-side language (like PHP, Java, .Net, or a server-side JavaScript stack like Node.js) to do the query.

Here's a tutorial on how to write some code that would bind PHP, JavaScript, and MySql together, with code running both in the browser, and on a server:

http://www.w3schools.com/php/php_ajax_database.asp

And here's the code from that page. It doesn't exactly match your scenario (it does a query, and doesn't store data in the DB), but it might help you start to understand the types of interactions you'll need in order to make this work.

In particular, pay attention to these bits of code from that article.

Bits of Javascript:

xmlhttp.open("GET","getuser.php?q="+str,true);
xmlhttp.send();

Bits of PHP code:

mysql_select_db("ajax_demo", $con);
$result = mysql_query($sql);
// ...
$row = mysql_fetch_array($result)
mysql_close($con);

Also, after you get a handle on how this sort of code works, I suggest you use the jQuery JavaScript library to do your AJAX calls. It is much cleaner and easier to deal with than the built-in AJAX support, and you won't have to write browser-specific code, as jQuery has cross-browser support built in. Here's the page for the jQuery AJAX API documentation.

The code from the article

HTML/Javascript code:

<html>
<head>
<script type="text/javascript">
function showUser(str)
{
if (str=="")
  {
  document.getElementById("txtHint").innerHTML="";
  return;
  } 
if (window.XMLHttpRequest)
  {// code for IE7+, Firefox, Chrome, Opera, Safari
  xmlhttp=new XMLHttpRequest();
  }
else
  {// code for IE6, IE5
  xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
  }
xmlhttp.onreadystatechange=function()
  {
  if (xmlhttp.readyState==4 && xmlhttp.status==200)
    {
    document.getElementById("txtHint").innerHTML=xmlhttp.responseText;
    }
  }
xmlhttp.open("GET","getuser.php?q="+str,true);
xmlhttp.send();
}
</script>

If you want to know if list element at index i is set or not, you can simply check the following:

if len(l)<=i:
    print ("empty")

If you are looking for something like what is a NULL-Pointer or a NULL-Reference in other languages, Python offers you None. That is you can write:

l[0] = None # here, list element at index 0 has to be set already
l.append(None) # here the list can be empty before
# checking
if l[i] == None:
    print ("list has actually an element at position i, which is None")

declare @MyNumber float 
set @MyNumber = 123.45 
select 'My number is ' + CAST(@MyNumber as nvarchar(max))

You can just tell Finder to open the .sh file in Terminal:

1. Select the file
2. Get Info (cmd-i) on it
3. In the "Open with" section, choose "Other…" in the popup menu
4. Choose Terminal as the application

This will have the exact same effect as renaming it to .command except… you don't have to rename it :)

Use numpy.concatenate(list1 , list2) or numpy.append() Look into the thread at Append a NumPy array to a NumPy array.

Hello There is an example:

    ptl.grid(True)
    return ptl.show()

You could also use tools provided by the base JRE:

String msg = "<message>HELLO!</message>";
DocumentBuilder newDocumentBuilder = DocumentBuilderFactory.newInstance().newDocumentBuilder();
Document parse = newDocumentBuilder.parse(new ByteArrayInputStream(msg.getBytes()));
System.out.println(parse.getFirstChild().getTextContent());

Yes, in AndroidManifest.xml, declare your Activity like so: <activity ... android:screenOrientation="landscape" .../>

Re-migrate approach for a cleaner plate.

This can painlessly be done IF other apps do not foreign key models from the app to be renamed. Check and make sure their migration files don't list any migrations from this one.

1. Backup your database. Dump all tables with a) data + schema for possible circular dependencies, and b) just data for reloading.
2. Run your tests.
3. Check all code into VCS.
4. Delete the database tables of the app to be renamed.
5. Delete the permissions: delete from auth_permission where content_type_id in (select id from django_content_type where app_label = '<OldAppName>')
6. Delete content types: delete from django_content_type where app_label = '<OldAppName>'
7. Rename the folder of the app.
8. Change any references to your app in their dependencies, i.e. the app's views.py, urls.py , 'manage.py' , and settings.py files.
9. Delete migrations: delete from django_migrations where app = '<OldAppName>'
10. If your models.py 's Meta Class has app_name listed, make sure to rename that too (mentioned by @will).
11. If you've namespaced your static or templates folders inside your app, you'll also need to rename those. For example, rename old_app/static/old_app to new_app/static/new_app.
12. If you defined app config in apps.py; rename those, and rename their references in settings.INSTALLED_APPS
13. Delete migration files.
14. Re-make migrations, and migrate.
15. Load your table data from backups.

The book HTML5 Guidelines for Web Developers: Structure and Semantics for Documents suggested this way (option 1):

<aside id="sidebar">
    <section id="widget_1"></section>
    <section id="widget_2"></section>
    <section id="widget_3"></section>
</aside>

It also points out that you can use sections in the footer. So section can be used outside of the actual page content.

I've been thinking about this too. From a C background, you can simulate function return code types, as well as, parameter types, using something like the following:

function top_function() {
    var rc;
    console.log("1st call");
    rc = Number(test_function("number", 1, "string", "my string"));
    console.log("typeof rc: " + typeof rc + "   rc: " + rc);
    console.log("2nd call");
    rc = Number(test_function("number", "a", "string", "my string"));
    console.log("typeof rc: " + typeof rc + "   rc: " + rc);
}
function test_function(parm_type_1, parm_val_1, parm_type_2, parm_val_2) {
    if (typeof parm_val_1 !== parm_type_1) console.log("Parm 1 not correct type");
    if (typeof parm_val_2 !== parm_type_2) console.log("Parm 2 not correct type");
    return parm_val_1;
}

The Number before the calling function returns a Number type regardless of the type of the actual value returned, as seen in the 2nd call where typeof rc = number but the value is NaN

the console.log for the above is:

1st call
typeof rc: number   rc: 1
2nd call
Parm 1 not correct type
typeof rc: number   rc: NaN

Not sure about the Java parsing, but that's ISO8601: http://en.wikipedia.org/wiki/ISO_8601

Let's Encrypt is a free, automated, and open certificate authority made by the Internet Security Research Group (ISRG). It is sponsored by well-known organisations such as Mozilla, Cisco or Google Chrome. All modern browsers are compatible and trust Let's Encrypt.

All certificates are free (even wildcard certificates)! For security reasons, the certificates expire pretty fast (after 90 days). For this reason, it is recommended to install an ACME client, which will handle automatic certificate renewal.

There are many clients you can use to install a Let's Encrypt certificate:

Let’s Encrypt uses the ACME protocol to verify that you control a given domain name and to issue you a certificate. To get a Let’s Encrypt certificate, you’ll need to choose a piece of ACME client software to use. - https://letsencrypt.org/docs/client-options/

IE is even worse with 2 connection per domain limit. But I wouldn't rely on fixing client browsers. Even if you have control over them, browsers like chrome will auto update and a future release might behave differently than you expect. I'd focus on solving the problem within your system design.

Your choices are to:

1. Load the images in sequence so that only 1 or 2 XHR calls are active at a time (use the success event from the previous image to check if there are more images to download and start the next request).

2. Use sub-domains like serverA.myphotoserver.com and serverB.myphotoserver.com. Each sub domain will have its own pool for connection limits. This means you could have 2 requests going to 5 different sub-domains if you wanted to. The downfall is that the photos will be cached according to these sub-domains. BTW, these don't need to be "mirror" domains, you can just make additional DNS pointers to the exact same website/server. This means you don't have the headache of administrating many servers, just one server with many DNS records.

Open report in Report designer

Go to View menu -> Report data

use:

std::vector <Acard> playerHand;

everywhere qualify it by std::

or do:

using std::vector;

in your cpp file.

You have to do this because vector is defined in the std namespace and you do not tell your program to find it in std namespace, you need to tell that.

The first thing you need to understand is that when you pass something to a function, that something is copied to the function's arguments.

Suppose you have the following:

void swap1(int a, int b) {
    int temp = a;
    a = b;
    b = temp;
    assert(a == 17);
    assert(b == 42);
    // they're swapped!
}

int x = 42;
int y = 17;
swap1(x, y);
assert(x == 42);
assert(y == 17);
// no, they're not swapped!

The original variables will not be swapped, because their values are copied into the function's arguments. The function then proceeds to swap the values of those arguments, and then returns. The original values are not changed, because the function only swaps its own private copies.

Now how do we work around this? The function needs a way to refer to the original variables, not copies of their values. How can we refer to other variables in C? Using pointers.

If we pass pointers to our variables into the function, the function can swap the values in our variables, instead of its own argument copies.

void swap2(int* a, int* b) {
    int temp = *a;
    *a = *b;
    *b = temp;
    assert(*a == 17);
    assert(*b == 42);
    // they're swapped!
}

int x = 42;
int y = 17;
swap2(&x, &y); // give the function pointers to our variables
assert(x == 17);
assert(y == 42);
// yes, they're swapped!

Notice how inside the function we're not assigning to the pointers, but assigning to what they point to. And the pointers point to our variables x and y. The function is changing directly the values stored in our variables through the pointers we give it. And that's exactly what we needed.

Now what happens if we have two pointer variables and want to swap the pointers themselves (as opposed to the values they point to)? If we pass pointers, the pointers will simply be copied (not the values they point to) to the arguments.

void swap3(int* a, int* b) {
    int* temp = a;
    a = b;
    b = temp;
    assert(*a == 17);
    assert(*b == 42);
    // they're swapped!
}
void swap4(int* a, int* b) {
    int temp = *a;
    *a = *b;
    *b = temp;
    assert(*a == 17);
    assert(*b == 42);
    // they're swapped!
}

int x = 42;
int y = 17;
int* xp = &x;
int* yp = &y;
swap3(xp, yp);
assert(xp == &x);
assert(yp == &y);
assert(x == 42);
assert(y == 17);
// Didn't swap anything!
swap4(xp, yp);
assert(xp == &x);
assert(yp == &y);
assert(x == 17);
assert(y == 42);
// Swapped the stored values instead!

The function swap3 only swaps its own private copies of our pointers that it gets in its arguments. It's the same issue we had with swap1. And swap4 is changing the values our variables point to, not the pointers! We're giving the function a means to refer to the variables x and y but we want them to refer to xp and yp.

How do we do that? We pass it their addresses!

void swap5(int** a, int** b) {
    int* temp = *a;
    *a = *b;
    *b = temp;
    assert(**a == 17);
    assert(**b == 42);
    // they're swapped!
}


int x = 42;
int y = 17;
int* xp = &x;
int* yp = &y;
swap5(&xp, &yp);
assert(xp == &y);
assert(yp == &x);
assert(x == 42);
assert(y == 17);
// swapped only the pointers variables

This way it swaps our pointer variables (notice how xp now points to y) but not the values they point to. We gave it a way to refer to our pointer variables, so it can change them!

By now it should be easy to understand how to swap two strings in the form of char* variables. The swap function needs to receive pointers to char*.

void swapStrings(char** a, char** b){
    char *temp = *a;
    *a = *b;
    *b = temp;
    assert(strcmp(*a, "world") == 0);
    assert(strcmp(*b, "Hello") == 0);
}

char* x = "Hello";
char* y = "world";
swapStrings(&x, &y);
assert(strcmp(x, "world") == 0);
assert(strcmp(y, "Hello") == 0);

No need to used grep here, Try this:

df . -B MB | tail -1 | awk {'print substr($5, 1, length($5)-1)'}

I have used sequelize.js, node.js and transaction in belowcode and added proper error handling if it doesn't find data it will throw error that no data found with that id

deleteMyModel: async (req, res) => {

    sequelize.sequelize.transaction(async (t1) => {

        if (!req.body.id) {
            return res.status(500).send(error.MANDATORY_FIELDS);
        }

        let feature = await sequelize.MyModel.findOne({
            where: {
                id: req.body.id
            }
        })

        if (feature) {
            let feature = await sequelize.MyModel.destroy({
                where: {
                    id: req.body.id
                }
            });

            let result = error.OK;
            result.data = MyModel;
            return res.status(200).send(result);

        } else {
            return res.status(404).send(error.DATA_NOT_FOUND);
        }
    }).catch(function (err) {
        return res.status(500).send(error.SERVER_ERROR);
    });
}

That's because you have the Date in American format in line[i] and UK format in the FormatString.

11/20/2011
M / d/yyyy

I'm guessing you might need to change the FormatString to:

"M/d/yyyy h:mm"

Use Linq-XML,

XDocument doc = XDocument.Load(file);

var result = from ele in doc.Descendants("sog")
              select new
              {
                 field1 = (string)ele.Element("field1")
              };
 foreach (var t in result)
  {
      HttpContext.Current.Response.Write(t.field1);
  }

OR : Get the node list of <sog> tag.

 XmlDocument xmlDoc = new XmlDocument();
 xmlDoc.Load(myXML);
 XmlNodeList parentNode = xmlDoc.GetElementsByTagName("sog");
 foreach (XmlNode childrenNode in parentNode)
  {
    HttpContext.Current.Response.Write(childrenNode.SelectSingleNode("field1").InnerText);
   }

Your problem is that you're not closing your HEREDOC correctly. The line containing END; must not contain any whitespace afterwards.

{{app.session}} refers to the Session object and not the $_SESSION array. I don't think the $_SESSION array is accessible unless you explicitly pass it to every Twig template or if you do an extension that makes it available.

Symfony2 is object-oriented, so you should use the Session object to set session attributes and not rely on the array. The Session object will abstract this stuff away from you so it is easier to, say, store the session in a database because storing the session variable is hidden from you.

So, set your attribute in the session and retrieve the value in your twig template by using the Session object.

// In a controller
$session = $this->get('session');
$session->set('filter', array(
    'accounts' => 'value',
));

// In Twig
{% set filter = app.session.get('filter') %}
{% set account-filter = filter['accounts'] %}

Hope this helps.

Matt

Below is the code for ImageFullViewActivity Class

 public class ImageFullViewActivity extends AppCompatActivity {

        private ScaleGestureDetector mScaleGestureDetector;
        private float mScaleFactor = 1.0f;
        private ImageView mImageView;

        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.image_fullview);

            mImageView = (ImageView) findViewById(R.id.imageView);
            mScaleGestureDetector = new ScaleGestureDetector(this, new ScaleListener());

        }

        @Override
        public boolean onTouchEvent(MotionEvent motionEvent) {
            mScaleGestureDetector.onTouchEvent(motionEvent);
            return true;
        }

        private class ScaleListener extends ScaleGestureDetector.SimpleOnScaleGestureListener {
            @Override
            public boolean onScale(ScaleGestureDetector scaleGestureDetector) {
                mScaleFactor *= scaleGestureDetector.getScaleFactor();
                mScaleFactor = Math.max(0.1f,
                        Math.min(mScaleFactor, 10.0f));
                mImageView.setScaleX(mScaleFactor);
                mImageView.setScaleY(mScaleFactor);
                return true;
            }
        }
    }

If you'd like to use base graphics, you may have a look at this. An extract:

You can correct this with the res= argument to png, which specifies the number of pixels per inch. The smaller this number, the larger the plot area in inches, and the smaller the text relative to the graph itself.

You can add an extension method to javascript.

Date.prototype.today = function () {
    return ((this.getDate() < 10) ? "0" : "") + this.getDate() + "/" + (((this.getMonth() + 1) < 10) ? "0" : "") + (this.getMonth() + 1) + "/" + this.getFullYear();
}

This is a not-hard approach:

<div>
    <img src="sample.jpg" />
</div>

then in css:
div {
    position: absolute;
}

img, div {
   width: ##%;
   height: ##%;
}

You are always checking for a true condition, hence your message will always show.

You should replace your if (true) statement with if ( n == JOptionPane.YES_OPTION)

When one of the showXxxDialog methods returns an integer, the possible values are:

YES_OPTION NO_OPTION CANCEL_OPTION OK_OPTION CLOSED_OPTION

From here

Try the following:

document.getElementById("successAndErrorMessages").innerHTML="someContent"; 

msdn link for detail : innerHTML Property

This three function are the same.

$(document).ready(function(){

}) 

and

$(function(){

}); 

and

jQuery(document).ready(function(){

});

here $ is used for define jQuery like $ = jQuery.

Now difference is that

$(document).ready is jQuery event that is fired when DOM is loaded, so it’s fired when the document structure is ready.

$(window).load event is fired after whole content is loaded like page contain images,css etc.

I tried following with ASP.NET MVC 5, its works for me

var sessionData = "@Session["SessionName"]";

The # tag lets you send your data to the same file. I see it as a three step process:

1. Query a DB to populate a from
2. Allow the user to change data in the form
3. Resubmit the data to the DB via the php script

With the method='#' you can do all of this in the same file.

After the submit query is executed the page will reload with the updated data from the DB.

This method takes all views inside a layout, this is similar to Alexander Kulyakhtin's answer. The difference is, it accepts any type of parent layouts & returns an Array List of views.

public List<View> getAllViews(ViewGroup layout){
        List<View> views = new ArrayList<>();
        for(int i =0; i< layout.getChildCount(); i++){
            views.add(layout.getChildAt(i));
        }
        return views;
}

Another solution is to update ViewPager height according to the current page height in its PagerAdapter. Assuming that your are creating your ViewPager pages this way:

@Override
public Object instantiateItem(ViewGroup container, int position) {
  PageInfo item = mPages.get(position);
  item.mImageView = new CustomImageView(container.getContext());
  item.mImageView.setImageDrawable(item.mDrawable);
  container.addView(item.mImageView, 0);
  return item;
}

Where mPages is internal list of PageInfo structures dynamically added to the PagerAdapter and CustomImageView is just regular ImageView with overriden onMeasure() method that sets its height according to specified width and keeps image aspect ratio.

You can force ViewPager height in setPrimaryItem() method:

@Override
public void setPrimaryItem(ViewGroup container, int position, Object object) {
  super.setPrimaryItem(container, position, object);

  PageInfo item = (PageInfo) object;
  ViewPager pager = (ViewPager) container;
  int width = item.mImageView.getMeasuredWidth();
  int height = item.mImageView.getMeasuredHeight();
  pager.setLayoutParams(new FrameLayout.LayoutParams(width, Math.max(height, 1)));
}

Note the Math.max(height, 1). That fixes annoying bug that ViewPager does not update displayed page (shows it blank), when previous page has zero height (i. e. null drawable in the CustomImageView), each odd swipe back and forth between two pages.

you can try with

document.getElementById('btn').disabled = !this.checked"

<input type="submit" name="btn"  id="btn" value="submit" disabled/>_x000D_
_x000D_
<input type="checkbox"  onchange="document.getElementById('btn').disabled = !this.checked"/>

I took on the idea of swapping the output stream to a my stream.

const LogLater                = require ('./loglater.js');
var logfile=new LogLater( 'log'+( new Date().toISOString().replace(/[^a-zA-Z0-9]/g,'-') )+'.txt' );


var PassThrough = require('stream').PassThrough;

var myout= new PassThrough();
var wasout=console._stdout;
myout.on('data',(data)=>{logfile.dateline("\r\n"+data);wasout.write(data);});
console._stdout=myout;

var myerr= new PassThrough();
var waserr=console._stderr;
myerr.on('data',(data)=>{logfile.dateline("\r\n"+data);waserr.write(data);});
console._stderr=myerr;

loglater.js:

const fs = require('fs');

function LogLater(filename, noduplicates, interval) {
    this.filename = filename || "loglater.txt";
    this.arr = [];
    this.timeout = false;
    this.interval = interval || 1000;
    this.noduplicates = noduplicates || true;
    this.onsavetimeout_bind = this.onsavetimeout.bind(this);
    this.lasttext = "";
    process.on('exit',()=>{ if(this.timeout)clearTimeout(this.timeout);this.timeout=false; this.save(); })
}

LogLater.prototype = {
    _log: function _log(text) {
        this.arr.push(text);
        if (!this.timeout) this.timeout = setTimeout(this.onsavetimeout_bind, this.interval);
    },
    text: function log(text, loglastline) {
        if (this.noduplicates) {
            if (this.lasttext === text) return;
            this.lastline = text;
        }
        this._log(text);
    },
    line: function log(text, loglastline) {
        if (this.noduplicates) {
            if (this.lasttext === text) return;
            this.lastline = text;
        }
        this._log(text + '\r\n');
    },
    dateline: function dateline(text) {
        if (this.noduplicates) {
            if (this.lasttext === text) return;
            this.lastline = text;
        }
        this._log(((new Date()).toISOString()) + '\t' + text + '\r\n');
    },
    onsavetimeout: function onsavetimeout() {
        this.timeout = false;
        this.save();
    },
    save: function save() { fs.appendFile(this.filename, this.arr.splice(0, this.arr.length).join(''), function(err) { if (err) console.log(err.stack) }); }
}

module.exports = LogLater;

From the Express site, define a NotFound exception and throw it whenever you want to have a 404 page OR redirect to /404 in the below case:

function NotFound(msg){
  this.name = 'NotFound';
  Error.call(this, msg);
  Error.captureStackTrace(this, arguments.callee);
}

NotFound.prototype.__proto__ = Error.prototype;

app.get('/404', function(req, res){
  throw new NotFound;
});

app.get('/500', function(req, res){
  throw new Error('keyboard cat!');
});

A few ideas:

1. When you refresh your page in Chrome, do a CTRL+F5 to do a full refresh.
2. Even if you set the expires to 0, it will still cache during the session. You'll have to close and re-open your browser again.
3. Make sure when you save the files on the server, the timestamps are getting updated. Chrome will first issue a HEAD command instead of a full GET to see if it needs to download the full file again, and the server uses the timestamp to see.

If you want to disable caching on your server, you can do something like:

Header set Expires "Thu, 19 Nov 1981 08:52:00 GM"
Header set Cache-Control "no-store, no-cache, must-revalidate, post-check=0, pre-check=0"
Header set Pragma "no-cache"

In .htaccess

Span is inline-block and adjusts to inline text size, with a tenacity that blocks most efforts to style out of inline context. To simplify layout style (limit conflicts), add div to 'p' tag with line break.

<p> some default stuff
<br>
<div style="text-align: center;"> your entered stuff </div>

Edit -- just saw your comment about the performance problems associated with a potentially bad piece of input data. I don't know offhand how try/catch on parseInt compares to a regex. I would guess, based on very little hard knowledge, that regexes are not hugely performant, compared to try/catch, in Java.

Anyway, I'd just do this:

public Integer tryParse(Object obj) {
  Integer retVal;
  try {
    retVal = Integer.parseInt((String) obj);
  } catch (NumberFormatException nfe) {
    retVal = 0; // or null if that is your preference
  }
  return retVal;
}

How do you expect List<EmailData>.Add to know how to turn three strings into an instance of EmailData? You're expecting too much of the Framework. There is no overload of List<T>.Add that takes in three string parameters. In fact, the only overload of List<T>.Add takes in a T. Therefore, you have to create an instance of EmailData and pass that to List<T>.Add. That is what the above code does.

Try:

lstemail.Add(new EmailData {
    FirstName = "JOhn", 
    LastName = "Smith",
    Location = "Los Angeles"
});

This uses the C# object initialization syntax. Alternatively, you can add a constructor to your class

public EmailData(string firstName, string lastName, string location) {
    this.FirstName = firstName;
    this.LastName = lastName;
    this.Location = location;
}

Then:

lstemail.Add(new EmailData("JOhn", "Smith", "Los Angeles"));

Because this is javascript and dynamic you could define your own class that matches the File interface and use that instead.

I had to do just that with dropzone.js because I wanted to simulate a file upload and it works on File objects.

Here is how this particular deadlock problem actually occurred and how it was actually resolved. This is a fairly active database with 130K transactions occurring daily. The indexes in the tables in this database were originally clustered. The client requested us to make the indexes nonclustered. As soon as we did, the deadlocking began. When we reestablished the indexes as clustered, the deadlocking stopped.

Always try to use parametrized sql query to keep safe from malicious occurrence, so you could rearrange you code as below:

Also make sure that your table has column name matches to Name, PhoneNo ,Address.

using (SqlConnection connection = new SqlConnection(connectionString))
{
    SqlCommand cmd = new SqlCommand("INSERT INTO Data (Name, PhoneNo, Address) VALUES (@Name, @PhoneNo, @Address)");
    cmd.CommandType = CommandType.Text;
    cmd.Connection = connection;
    cmd.Parameters.AddWithValue("@Name", txtName.Text);
    cmd.Parameters.AddWithValue("@PhoneNo", txtPhone.Text);
    cmd.Parameters.AddWithValue("@Address", txtAddress.Text);
    connection.Open();
    cmd.ExecuteNonQuery();
}

If you are using jQuery, there is a redirect plugin that works with the POST or GET method. It creates a form with hidden inputs and submits it for you. An example of how to get it working:

$.redirect('demo.php', {'arg1': 'value1', 'arg2': 'value2'});

Note: You can pass the method types GET or POST as an optional third parameter; POST is the default.

Add -ErrorAction SilentlyContinue to your script and you'll be good to go.

If I recall correctly Twig doesn't support || and && operators, but requires or and and to be used respectively. I'd also use parentheses to denote the two statements more clearly although this isn't technically a requirement.

{%if ( fields | length > 0 ) or ( trans_fields | length > 0 ) %}

Expressions

Expressions can be used in {% blocks %} and ${ expressions }.

Operator    Description
==          Does the left expression equal the right expression?
+           Convert both arguments into a number and add them.
-           Convert both arguments into a number and substract them.
*           Convert both arguments into a number and multiply them.
/           Convert both arguments into a number and divide them.
%           Convert both arguments into a number and calculate the rest of the integer division.
~           Convert both arguments into a string and concatenate them.
or          True if the left or the right expression is true.
and         True if the left and the right expression is true.
not         Negate the expression.

For more complex operations, it may be best to wrap individual expressions in parentheses to avoid confusion:

{% if (foo and bar) or (fizz and (foo + bar == 3)) %}

As Distdev alluded to, you still need to differentiate the input type. That is to say,

$(this).prev().prop('tagName');

will tell you input, but that doesn't differentiate between checkbox/text/radio. If it's an input, you can then use

$('#elementId').attr('type');

to tell you checkbox/text/radio, so you know what kind of control it is.

I find the "parseInt" suggestions to be pretty curious, because "parseInt" operates on strings by design. That's why its name has the word "parse" in it.

A trick that avoids a function call entirely is

var truncated = ~~number;

The double application of the "~" unary operator will leave you with a truncated version of a double-precision value. However, the value is limited to 32 bit precision, as with all the other JavaScript operations that implicitly involve considering numbers to be integers (like array indexing and the bitwise operators).

edit — In an update quite a while later, another alternative to the ~~ trick is to bitwise-OR the value with zero:

var truncated = number|0;

Directly from the GitHub project homepage:

Dapper allow you to pass in IEnumerable and will automatically parameterize your query.

connection.Query<int>(
    @"select * 
      from (select 1 as Id union all select 2 union all select 3) as X 
      where Id in @Ids", 
    new { Ids = new int[] { 1, 2, 3 });

Will be translated to:

select * 
from (select 1 as Id union all select 2 union all select 3) as X 
where Id in (@Ids1, @Ids2, @Ids3)

// @Ids1 = 1 , @Ids2 = 2 , @Ids2 = 3

Prior to Java 8:

The static variables were stored in the permgen space(also called the method area).

PermGen Space is also known as Method Area

PermGen Space used to store 3 things

1. Class level data (meta-data)
2. interned strings
3. static variables

From Java 8 onwards

The static variables are stored in the Heap itself.From Java 8 onwards the PermGen Space have been removed and new space named as MetaSpace is introduced which is not the part of Heap any more unlike the previous Permgen Space. Meta-Space is present on the native memory (memory provided by the OS to a particular Application for its own usage) and it now only stores the class meta-data.

The interned strings and static variables are moved into the heap itself.

For official information refer : JEP 122:Remove the Permanent Gen Space

Say, for an user, there is revision for each date. The following will pick up record for the max revision of each date for each employee.

select job, adate, rev, usr, typ 
from tbl
where exists (  select 1 from ( select usr, adate, max(rev) as max_rev 
                                from tbl
                                group by usr, adate 
                              ) as cond
                where tbl.usr=cond.usr 
                and tbl.adate =cond.adate 
                and tbl.rev =cond.max_rev
             )
order by adate, job, usr

If you want a GUI to access SVN repos you can use http://tortoisesvn.tigris.org/ (and its Repobrwoser) If you want a browser based tool, to browse ANY SVN repo without installing SVn on your machine, i don't such a tool. I know only tools to install to your webserver and needed a installed SVN client on these server. To checkout or export a svn repo you need a svn client. (or you copy the files from the command line =) )

try this

satView.setOnCheckedChangeListener(new android.widget.CompoundButton.OnCheckedChangeListener.OnCheckedChangeListener() {
        @Override
        public void onCheckedChanged(RadioGroup group, int checkedId) {
            if (isChecked){
                // perform logic
            }
        }

    });

Just:
