It is typically considered good practice to default to the lowest visibility required as this promotes data encapsulation and good interface design. When considering member variable and method visibility think about the role the member plays in the interaction with other objects.

If you "code to an interface rather than implementation" then it's usually pretty straightforward to make visibility decisions. In general, variables should be private or protected unless you have a good reason to expose them. Use public accessors (getters/setters) instead to limit and regulate access to a class's internals.

To use a car as an analogy, things like speed, gear, and direction would be private instance variables. You don't want the driver to directly manipulate things like air/fuel ratio. Instead, you expose a limited number of actions as public methods. The interface to a car might include methods such as accelerate(), deccelerate()/brake(), setGear(), turnLeft(), turnRight(), etc.

The driver doesn't know nor should he care how these actions are implemented by the car's internals, and exposing that functionality could be dangerous to the driver and others on the road. Hence the good practice of designing a public interface and encapsulating the data behind that interface.

This approach also allows you to alter and improve the implementation of the public methods in your class without breaking the interface's contract with client code. For example, you could improve the accelerate() method to be more fuel efficient, yet the usage of that method would remain the same; client code would require no changes but still reap the benefits of your efficiency improvement.

Edit: Since it seems you are still in the midst of learning object oriented concepts (which are much more difficult to master than any language's syntax), I highly recommend picking up a copy of PHP Objects, Patterns, and Practice by Matt Zandstra. This is the book that first taught me how to use OOP effectively, rather than just teaching me the syntax. I had learned the syntax years beforehand, but that was useless without understanding the "why" of OOP.

In foreach loop instead of carBootSaleList use carBootSaleList.data.

You probably do not need answer anymore, but it could help someone.

Sure you know, but if its a constant then const MyVariable as Integer = 123 otherwise your out of luck; the variable must be assigned an initial value elsewhere.

You could:

public property get myIntegerThing() as integer
    myIntegerThing= 123
end property

In a Class module then globally create it;

public cMyStuff as new MyStuffClass

So cMyStuff.myIntegerThing is available immediately.

The official tutorial may be of some use to you.

+ : accessible
blank : not accessible

You can do the following to learn/test the concept:

1. Open new Excel Workbook and in Excel VBA editor right-click on Modules->Insert->Module

2. In newly added Module1 add the declaration; Public Global1 As String

3. in Worksheet VBA Module Sheet1(Sheet1) put the code snippet:

Sub setMe()
      Global1 = "Hello"
End Sub

4. in Worksheet VBA Module Sheet2(Sheet2) put the code snippet:

Sub showMe()
    Debug.Print (Global1)
End Sub

5. Run in sequence Sub setMe() and then Sub showMe() to test the global visibility/accessibility of the var Global1

Hope this will help.

Add getter and setter method to your class.

public function setValue($new_value)
{
    $this->testvar = $new_value;
}

public function getValue()
{
    return $this->testvar;        
}

Only call time pass-by-reference is removed. So change:

call_user_func($func, &$this, &$client ...

To this:

call_user_func($func, $this, $client ...

&$this should never be needed after PHP4 anyway period.

If you absolutely need $client to be passed by reference, update the function ($func) signature instead (function func(&$client) {)

If you have the error after setup a new https vhost and the config seems to be right, remember to link in sites-enabled too.

I have this similar problem where I'm able to start the tomcat server but however application not initialized or started, so I have Right clicked on my project --> Deployment Assembly --> Click 'Add' in the right side panel, select 'Java Build path entries' and click 'Next', Now select 'Maven dependencies' and click 'Finish'. Now I run the server and it started the application successfully.

I know there were several perfect answers but I found this page useful as well !

Quote from the site:

The Feature Graphic is used for promotions on Google Play. While this graphic is not required to save and publish your Store Listing, it is required in order to be featured on Google Play.

Commentary:

To be clear, these "promotions" are chosen at Google's discretion. Even though excellent the "This is a test" app demonstration (above) shows the Feature graphic used in common areas of the outdated "Android Market", this is no longer the case with today's "Play Store".

Quote from the site:

The Promo Graphic is used for promotions on older versions of the Android OS (earlier than 4.0). This image is not required to save and publish your Store Listing.

Commentary:

It appears that this is also at Google's discretion and not always used as the "This is a test" demo suggests. Even though an older device may not get an update to their Android version, the "Android Market" update bringing them to a modern version of "Play Store" should be available.

Building on @joris response above, if you have already established a reference to the subplot, you can use the reference as well. For example,

ax1 = plt.subplot2grid((50,100), (0, 0), colspan=20, rowspan=10)
...

df.plot.barh(ax=ax1, stacked=True)

I suppose rgba() would work here. After all, browser support for both box-shadow and rgba() is roughly the same.

/* 50% black box shadow */
box-shadow: 10px 10px 10px rgba(0, 0, 0, 0.5);

div {_x000D_
    width: 200px;_x000D_
    height: 50px;_x000D_
    line-height: 50px;_x000D_
    text-align: center;_x000D_
    color: white;_x000D_
    background-color: red;_x000D_
    margin: 10px;_x000D_
}_x000D_
_x000D_
div.a {_x000D_
  box-shadow: 10px 10px 10px #000;_x000D_
}_x000D_
_x000D_
div.b {_x000D_
  box-shadow: 10px 10px 10px rgba(0, 0, 0, 0.5);_x000D_
}

<div class="a">100% black shadow</div>_x000D_
<div class="b">50% black shadow</div>

You can call tesseract API function from C code:

#include <tesseract/baseapi.h>
#include <tesseract/ocrclass.h>; // ETEXT_DESC

using namespace tesseract;

class TessAPI : public TessBaseAPI {
    public:
    void PrintRects(int len);
};

...
TessAPI *api = new TessAPI();
int res = api->Init(NULL, "rus");
api->SetAccuracyVSpeed(AVS_MOST_ACCURATE);
api->SetImage(data, w0, h0, bpp, stride);
api->SetRectangle(x0,y0,w0,h0);

char *text;
ETEXT_DESC monitor;
api->RecognizeForChopTest(&monitor);
text = api->GetUTF8Text();
printf("text: %s\n", text);
printf("m.count: %s\n", monitor.count);
printf("m.progress: %s\n", monitor.progress);

api->RecognizeForChopTest(&monitor);
text = api->GetUTF8Text();
printf("text: %s\n", text);
...
api->End();

And build this code:

g++ -g -I. -I/usr/local/include -o _test test.cpp -ltesseract_api -lfreeimageplus

(i need FreeImage for picture loading)

In eclipse,

• Install Jaspersoft Studio for eclipse.
• Right click the .jrxml file and select Open with JasperReports Book Editor
• Open the Design tab for the .jrxml file.
• On top of the window you can see the Compile Report icon.

The regular expression would be:

.+name="([^"]+)"

Then the grouping would be in the \1

add the following in your terminal and click enter then follow the instruction in the terminal. /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

You could use val().

var value = $('#area1').val();
$('#VAL_DISPLAY').html(value);

Other answers are excellent, though I still wanted to share a different approach in case someone is looking for alternatives.

Main difference here is that using this approach you can use HTML/CSS to format your message, so you can get creative and give some styling to your email. Though you aren't enforced to use HTML, you can also still use only plain text.

Notice that this function accepts sending the email to multiple recipients and also allows to attach multiple files.

I've only tried this on Python 2, but I think it should work fine on 3 as well:

import os.path
import smtplib
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText
from email.mime.application import MIMEApplication

def send_email(subject, message, from_email, to_email=[], attachment=[]):
    """
    :param subject: email subject
    :param message: Body content of the email (string), can be HTML/CSS or plain text
    :param from_email: Email address from where the email is sent
    :param to_email: List of email recipients, example: ["[email protected]", "[email protected]"]
    :param attachment: List of attachments, exmaple: ["file1.txt", "file2.txt"]
    """
    msg = MIMEMultipart()
    msg['Subject'] = subject
    msg['From'] = from_email
    msg['To'] = ", ".join(to_email)
    msg.attach(MIMEText(message, 'html'))

    for f in attachment:
        with open(f, 'rb') as a_file:
            basename = os.path.basename(f)
            part = MIMEApplication(a_file.read(), Name=basename)

        part['Content-Disposition'] = 'attachment; filename="%s"' % basename
        msg.attach(part)

    email = smtplib.SMTP('your-smtp-host-name.com')
    email.sendmail(from_email, to_email, msg.as_string())

I hope this helps! :-)

First of all, the fact that the value in the database is a float does not mean that it also fits in a Java float. Float is short for floating point, and floating point types of various precisions exist. Java types float and double are both floating point types of different precision. In a database both are called FLOAT. Since double has a higher precision than float, it probably is a better idea not to cast your value to a float, because you might lose precision.

You might also use BigDecimal, which represent an arbitrary-precision number.

As explained by Ron, there are two variables, local and global. The local variable is always used, and is the same as global upon connection.

SET FOREIGN_KEY_CHECKS=0;
SET GLOBAL FOREIGN_KEY_CHECKS=0;

SHOW Variables WHERE Variable_name='foreign_key_checks'; # always shows local variable

When setting the GLOBAL variable, the local one isn't changed for any existing connections. You need to reconnect or set the local variable too.

Perhaps unintuitive, MYSQL does not enforce foreign keys when FOREIGN_KEY_CHECKS are re-enabled. This makes it possible to create an inconsistent database even though foreign keys and checks are on.

If you want your foreign keys to be completely consistent, you need to add the keys while checking is on.

$(".thumbs").hover(
    function(){
        if (!$(this).hasClass("selected")) {
            $(this).stop().fadeTo("normal", 1.0);
        }
    },
    function(){
        if (!$(this).hasClass("selected")) {
            $(this).stop().fadeTo("slow", 0.3); 
        }           
    }
);

Putting an if inside of each part of the hover will allow you to change the select class dynamically and the hover will still work.

$(".thumbs").click(function() {
    $(".thumbs").each(function () {
        if ($(this).hasClass("selected")) {
            $(this).removeClass("selected");
            $(this).hover();
        }
    });                 
    $(this).addClass("selected");                   
});

As an example I've also attached a click handler to switch the selected class to the clicked item. Then I fire the hover event on the previous item to make it fade out.

It seems to me you are using the wrong version...

TAP-Win32 should not be installed on the 64bit version. Download the right one and try again!

Both VS Code extensions can be used:

1. 'Bookmarks'
2. 'Numbered Bookmarks'

Personally, I'm suggesting: Numbered Bookmarks, with 'navigate through all files' option:

1. ctrl + Shift + P in VS Code
2. In newly open field, type: Open User Settings
3. Paste this key/value: "numberedBookmarks.navigateThroughAllFiles": "allowDuplicates" (allow duplicates of bookmarks),
4. Or, paste this key/value: "numberedBookmarks.navigateThroughAllFiles": "replace"

NOTE

Either way, be careful with shortcuts (Ctrl+1, Ctrl+Shift+1,..) that are already assigned.

Personally, mine were in 2 conflicts, with:

1. VS Code shortcuts, that already exists,
2. Ditto clipboard (I've got paste on each call of bookmark)

One way is to use a script tag to import the variables you want to your views:

<script type="text/javascript">
window.base_url = <?php echo json_encode(base_url()); ?>;
</script>

Here, I wrapped the base_url with json_encode so that it'll automatically escape any characters to valid Javascript. I put base_url to the global Window so you can use it anywhere just by calling base_url, but make sure to put the script tag above any Javascript that calls it. With your given example:

...
$('#style_color').attr("href", base_url + "assets/css/themes/" + color_ + ".css");

Update for HTTPS:

GitHub has launched a new program for Windows that stores your credentials when you're using HTTPS:

To use:

• Download the program from here

• Once you run the program, it will edit your .gitconfig file. Recheck if it edited the correct .gitconfig in case you have several of them. If it didn't edit the correct one, add the following to your .gitconfig

  [credential]
      helper = !'C:\\Path\\To\\Your\\Downloaded\\File\\git-credential-winstore.exe'
  

  NOTE the line break after [credential]. It is required.

• Open up your command line client and try git push origin master once. If it asks you for a password, enter it and you're through. Password saved!

Given -

<input name="foo" type="text" value="foo" readonly />

this works - (jquery 1.7.1)

$('input[name="foo"]').prop('readonly', true);

tested with readonly and readOnly - both worked.

The table normally contains multiple rows. Use a loop and use row.Field<string>(0) to access the value of each row.

foreach(DataRow row in dt.Rows)
{
    string file = row.Field<string>("File");
}

You can also access it via index:

foreach(DataRow row in dt.Rows)
{
    string file = row.Field<string>(0);
}

If you expect only one row, you can also use the indexer of DataRowCollection:

string file = dt.Rows[0].Field<string>(0); 

Since this fails if the table is empty, use dt.Rows.Count to check if there is a row:

if(dt.Rows.Count > 0)
    file = dt.Rows[0].Field<string>(0);

You can verify where your Setting.xml is by pressing shortcut Ctrl+3, you will see Quick Access on top right side of Eclipse, then search setting.xml in searchbox. If you got setting.xml it will show up in search. Click that, and it will open the window showing directory path wherever it is stored. Your Maven Global Settings should be as such:

Global Setting C:\maven\apache-maven-3.5.0\conf\settings.xml
User Setting %userprofile%\\.m2\setting.xml
You can use global setting usually and leave the second option user setting untouched. Store your setting.xml in Global Setting

You can somehow try this:

Spawned window:

window.onunload = function (e) {
    opener.somefunction(); //or
    opener.document.getElementById('someid').innerHTML = 'update content of parent window';
};

Parent Window:

window.open('Spawn.htm','');
window.somefunction = function(){

}

You should not do this on the parent, otherwise opener.somefunction() will not work, doing window.somefunction makes somefunction as public:

function somefunction(){

}

This usually happens when you use two ssh keys to access two different GitHub account.

Follow these steps to fix this it look too long but trust me it won't take more than 5 minutes:

Step-1: Create two ssh key pairs:

ssh-keygen -t rsa -C "[email protected]"

Step-2: It will create two ssh keys here:

~/.ssh/id_rsa_account1
~/.ssh/id_rsa_account2

Step-3: Now we need to add these keys:

ssh-add ~/.ssh/id_rsa_account2
ssh-add ~/.ssh/id_rsa_account1

• You can see the added keys list by using this command: ssh-add -l
• You can remove old cached keys by this command: ssh-add -D

Step-4: Modify the ssh config

cd ~/.ssh/
touch config

subl -a config or code config or nano config

Step-5: Add this to config file:

#Github account1
Host github.com-account1
    HostName github.com
    User account1
    IdentityFile ~/.ssh/id_rsa_account1

#Github account2
Host github.com-account2
    HostName github.com
    User account2
    IdentityFile ~/.ssh/id_rsa_account2

Step-6: Update your .git/config file:

Step-6.1: Navigate to account1's project and update host:

[remote "origin"]
        url = [email protected]:account1/gfs.git

If you are invited by some other user in their git Repository. Then you need to update the host like this:

[remote "origin"]
            url = [email protected]:invitedByUserName/gfs.git

Step-6.2: Navigate to account2's project and update host:

[remote "origin"]
        url = [email protected]:account2/gfs.git

Step-7: Update user name and email for each repository separately if required this is not an amendatory step:

Navigate to account1 project and run these:

git config user.name "account1"
git config user.email "[email protected]" 

Navigate to account2 project and run these:

git config user.name "account2"
git config user.email "[email protected]" 

To start redis with a config file all you need to do is specifiy the config file as an argument:

redis-server /root/config/redis.rb

Instead of using and killing PID's I would suggest creating an init script for your service

I would suggest taking a look at the Installing Redis more properly section of http://redis.io/topics/quickstart. It will walk you through setting up an init script with redis so you can just do something like service redis_server start and service redis_server stop to control your server.

I am not sure exactly what distro you are using, that article describes instructions for a Debian based distro. If you are are using a RHEL/Fedora distro let me know, I can provide you with instructions for the last couple of steps, the config file and most of the other steps will be the same.

All the three syntax work very well.

Another way is to first write

path = r'C:\user\...................' (whatever is the path for you)

and then passing it to os.chdir(path)

I'm forced to post this as an answer instead of a comment due to low reputation. I had a similar problem to Matteo. The difference being that I had no map from my first x-axis to my second x-axis, only the x-values themselves. So I wanted to set the data on my second x-axis directly, not the ticks, however, there is no axes.set_xdata. I was able to use Dhara's answer to do this with a modification:

ax2.lines = []

instead of using:

ax2.cla()

When in use also cleared my plot from ax1.

You could use replicate or sapply:

R> colMeans(replicate(10000, sample(100, size=815, replace=TRUE, prob=NULL))) R> sapply(seq_len(10000), function(...) mean(sample(100, size=815, replace=TRUE, prob=NULL))) 

replicate is a wrapper for the common use of sapply for repeated evaluation of an expression (which will usually involve random number generation).

Client-side validation was not being executed at all on my web form and I had no idea why. It turns out the problem was the name of the javascript function was the same as the server control ID.

So you can't do this...

<script>
  function vld(sender, args) { args.IsValid = true; }
</script>
<asp:CustomValidator runat="server" id="vld" ClientValidationFunction="vld" />

But this works:

<script>
  function validate_vld(sender, args) { args.IsValid = true; }
</script>
<asp:CustomValidator runat="server" id="vld" ClientValidationFunction="validate_vld" />

I'm guessing it conflicts with internal .NET Javascript?

time is a built-in command in most shells that writes execution time information to the tty.

You could also try something like

start_time=`date +%s`
<command-to-execute>
end_time=`date +%s`
echo execution time was `expr $end_time - $start_time` s.

Or in bash:

start_time=`date +%s`
<command-to-execute> && echo run time is $(expr `date +%s` - $start_time) s

I believe the first appearance of iterators and generators were in the Icon programming language, about 20 years ago.

You may enjoy the Icon overview, which lets you wrap your head around them without concentrating on the syntax (since Icon is a language you probably don't know, and Griswold was explaining the benefits of his language to people coming from other languages).

After reading just a few paragraphs there, the utility of generators and iterators might become more apparent.

Probably you didn't provide an argument on the command line. In that case, sys.argv only contains one value, but it would have to have two in order to provide values for both user_name and script.

You have to use a different background image, not color, for each state of the EditText (focus, enabled, activated).

http://android-holo-colors.com/

In the site above, you can get images from a lot of components in the Holo theme. Just select "EditText" and the color you want. You can see a preview at the bottom of the page.

Download the .zip file, and copy paste the resources in your project (images and the XML).

if your XML is named: apptheme_edit_text_holo_light.xml (or something similar):

1. Go to your XML "styles.xml" and add the custom EditText style:

   <style name="EditTextCustomHolo" parent="android:Widget.EditText">
      <item name="android:background">@drawable/apptheme_edit_text_holo_light</item>
      <item name="android:textColor">#ffffff</item>
   </style>
   

2. Just do this in your EditText:

   <EditText
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"
      style="@style/EditTextCustomHolo"/>
   

And that's it, I hope it helps you.

I got the same error and when I unknowingly removed all the default pages of the DefaultAppPool itself.

Resolution

I have clicked the DefaultAppPool and opened the Default Document. Then clicked on the Revert to Parent link on the Actions pane. The default documents have came again, and thus it solves the issue. I'm not sure this is the best way, but this one was the error which I have just met and hope to share with you. I hope this may help some one.

If you are using electron or other chromium frame, you have to include jquery within window explicitly by:

<script language="javascript" type="text/javascript" src="local_path/jquery.js" onload="window.$ = window.jQuery = module.exports;"></script>

I have similar problems, in my case seem to be related to network connectivity:

Error Domain=NSURLErrorDomain Code=-1001 "The request timed out."

Things to check:

• Is there any chance that your server is not able to respond within some time limit? Like 60 seconds or 4 minutes?
• Is there a possibility that your device is switching networks (WiFi, 3G, VPN)?
• Could someone (client vs. server) be waiting for authentication?

Sorry, no ideas how to fix. Just debugging this, trying to find out what the problem is (-1021, -1001, -1009)

Update: Google search was very kind to find this:

• -1001 TimedOut - it took longer than the timeout which was alotted.
• -1003 CannotFindHost - the host could not be found.
• -1004 CannotConnectToHost - the host would not let us establish a connection.

__construct was introduced in PHP5 and it is the right way to define your, well, constructors (in PHP4 you used the name of the class for a constructor). You are not required to define a constructor in your class, but if you wish to pass any parameters on object construction then you need one.

An example could go like this:

class Database {
  protected $userName;
  protected $password;
  protected $dbName;

  public function __construct ( $UserName, $Password, $DbName ) {
    $this->userName = $UserName;
    $this->password = $Password;
    $this->dbName = $DbName;
  }
}

// and you would use this as:
$db = new Database ( 'user_name', 'password', 'database_name' );

Everything else is explained in the PHP manual: click here

Unable to load Client Print Control!
Everytime, clients wanted to print report by clicking the button print on their report viewer, they always got this error message.

I had spent nearly two weeks to fix this problem.
My environment is:
- Window Server 2003 Standard Edition R2
- Report Server Version 10.X.X.X
- Clients with windowXP SP3
My Solution is:
- Replacing the CAP file (RSClientPrint-x86.cab) in C\Program Files\Microsoft SQL
Server\MSRS10.MSSQLSERVER\Reporting Services\ReportServer\bin\
- Extract the RSClientPrint-x86.cab and destribute it to clients.


Hear is the CAB file: https://sites.google.com/site/narithsite/Home/RSClientPrint-x86.cab?attredirects=0&d=1

Try something like this:

public boolean checkNull() throws IllegalAccessException {
    for (Field f : getClass().getDeclaredFields())
        if (f.get(this) != null)
            return false;
    return true;            
}

Although it would probably be better to check each variable if at all feasible.

For those running Laravel Mix with npm run watch, just terminate the script and run the command again.

If you mean using an attribute selector, sure, why not:

[data-role="page"] {
    /* Styles */
}

There are a variety of attribute selectors you can use for various scenarios which are all covered in the document I link to. Note that, despite custom data attributes being a "new HTML5 feature",

• browsers typically don't have any problems supporting non-standard attributes, so you should be able to filter them with attribute selectors; and

• you don't have to worry about CSS validation either, as CSS doesn't care about non-namespaced attribute names as long as they don't break the selector syntax.

How do I check if something is (not) in a list in Python?

The cheapest and most readable solution is using the in operator (or in your specific case, not in). As mentioned in the documentation,

The operators in and not in test for membership. x in s evaluates to True if x is a member of s, and False otherwise. x not in s returns the negation of x in s.

Additionally,

The operator not in is defined to have the inverse true value of in.

y not in x is logically the same as not y in x.

Here are a few examples:

'a' in [1, 2, 3]
# False

'c' in ['a', 'b', 'c']
# True

'a' not in [1, 2, 3]
# True

'c' not in ['a', 'b', 'c']
# False

This also works with tuples, since tuples are hashable (as a consequence of the fact that they are also immutable):

(1, 2) in [(3, 4), (1, 2)]
#  True

If the object on the RHS defines a __contains__() method, in will internally call it, as noted in the last paragraph of the Comparisons section of the docs.

... in and not in, are supported by types that are iterable or implement the __contains__() method. For example, you could (but shouldn't) do this:

[3, 2, 1].__contains__(1)
# True

in short-circuits, so if your element is at the start of the list, in evaluates faster:

lst = list(range(10001))
%timeit 1 in lst
%timeit 10000 in lst  # Expected to take longer time.

68.9 ns ± 0.613 ns per loop (mean ± std. dev. of 7 runs, 10000000 loops each)

If you want to do more than just check whether an item is in a list, there are options:

• list.index can be used to retrieve the index of an item. If that element does not exist, a ValueError is raised.
• list.count can be used if you want to count the occurrences.

The XY Problem: Have you considered sets?

Ask yourself these questions:

• do you need to check whether an item is in a list more than once?
• Is this check done inside a loop, or a function called repeatedly?
• Are the items you're storing on your list hashable? IOW, can you call hash on them?

If you answered "yes" to these questions, you should be using a set instead. An in membership test on lists is O(n) time complexity. This means that python has to do a linear scan of your list, visiting each element and comparing it against the search item. If you're doing this repeatedly, or if the lists are large, this operation will incur an overhead.

set objects, on the other hand, hash their values for constant time membership check. The check is also done using in:

1 in {1, 2, 3} 
# True

'a' not in {'a', 'b', 'c'}
# False

(1, 2) in {('a', 'c'), (1, 2)}
# True

If you're unfortunate enough that the element you're searching/not searching for is at the end of your list, python will have scanned the list upto the end. This is evident from the timings below:

l = list(range(100001))
s = set(l)

%timeit 100000 in l
%timeit 100000 in s

2.58 ms ± 58.9 µs per loop (mean ± std. dev. of 7 runs, 100 loops each)
101 ns ± 9.53 ns per loop (mean ± std. dev. of 7 runs, 10000000 loops each)

As a reminder, this is a suitable option as long as the elements you're storing and looking up are hashable. IOW, they would either have to be immutable types, or objects that implement __hash__.

javascript:document.getElementsByClassName("video-stream html5-main-video")[0].playbackRate = 0.1;

you can put any number here just don't go to far so you don't overun your computer.

If you're willing to use a Volume and a ConfigMap, you can mount ConfigMap data as a script, and then run that script:

---
apiVersion: v1
kind: ConfigMap
metadata:
  name: my-configmap
data:
  entrypoint.sh: |-
    #!/bin/bash
    echo "Do this"

    echo "Do that"
---
apiVersion: v1
kind: Pod
metadata:
  name: my-pod
spec:
  containers:
  - name: my-container
    image: "ubuntu:14.04"
    command:
    - /bin/entrypoint.sh
    volumeMounts:
    - name: configmap-volume
      mountPath: /bin/entrypoint.sh
      readOnly: true
      subPath: entrypoint.sh
  volumes:
  - name: configmap-volume
    configMap:
      defaultMode: 0700
      name: my-configmap

This cleans up your pod spec a little and allows for more complex scripting.

$ kubectl logs my-pod
Do this
Do that

util.format does this.

It will be part of v0.5.3 and can be used like this:

var uri = util.format('http%s://%s%s', 
      (useSSL?'s':''), apiBase, path||'/');

$target.hide('slow');

or

$target.hide('slow', function(){ $target.remove(); });

to run the animation, then remove it from DOM

No. Either use readFile or readFileSync (The latter only at startup time).

Or use an existing library like

• cjson

Alternatively write your config in a js file rather then a json file like

module.exports = {
  // json
}

Super Key : Super key is a set of one or more attributes whose values identify tuple in the relation uniquely.

Candidate Key : Candidate key can be defined as a minimal subset of super key. In some cases , candidate key can not alone since there is alone one attribute is the minimal subset. Example,

Employee(id, ssn, name, addrress)

Here Candidate key is (id, ssn) because we can easily identify the tuple using either id or ssn . Althrough, minimal subset of super key is either id or ssn. but both of them can be considered as candidate key.

Primary Key : Primary key is a one of the candidate key.

Example : Student(Id, Name, Dept, Result)

Here

Super Key : {Id, Id+Name, Id+Name+Dept} because super key is set of attributes .

Candidate Key : Id because Id alone is the minimal subset of super key.

Primary Key : Id because Id is one of the candidate key

Just go with the command py. I'm running python 3.6.2 on windows 7 and it works just fine.
I removed all the python paths from the system directory and the paths don't show up when I run the command echo %path% in cmd. Python is still working fine.
I ran into this by accidentally pressing enter while typing python...

EDIT: I didn't mention that I installed python to a custom folder C:\Python\

This is the shortest command I could find that does the job:

ps -ax | awk '/[t]he_app_name/{print $1}'

Putting brackets around the first letter stops awk from finding the awk process itself.

I started to use

git show-branch --no-name <hash>

It seems to be faster than

git show -s --format=%s <hash>

Both give the same result

I actually wrote a small tool to see the status of all my repos. You can find it on github.

I've read all the answers and many have been deprecated.

This is how currently you can clear and set the place holder value:

// Clear and put a blank select placeholder
$("#MySelect").prop('disabled', false).find("option:gt(0)").remove();

Try reindex.

UPDATE: As pointed out in the comments, this was in reply to the original question.

Angular 6+ Singleton Services

The recommended approach for a singleton service for Angular 6 and beyond is :

import { Injectable } from '@angular/core';

@Injectable({
  providedIn: 'root',
})
export class UserService {
}

In fact the CLI --module switch doesn't even exist any more for registering a service at the app level because it doesn't need to modify app.module.ts anymore.

This will create the above code, without needing to specify a module.

ng g s services/user

So if you don't want your service to be a singleton you must remove the providedIn code yourself - and then add it manually to providers for a component or lazy loaded module. Doesn't look like there is currently a switch to not generate the providedIn: 'root' part so you need to manually remove it.

whenever you deal with spaces in filenames, use quotes

net use "m:\Server01\my folder" /USER:mynetwork\Administrator "Mypassword" /persistent:yes

The following works on all browsers for my 200 figures, for any width percentage -- despite being illegal. Jukka said 'Use it anyway.' (The class just floats the image left or right and sets margins.) I can't imagine why this isn't the standard approach!

<img class="fl" width="66%"
src="A-Images/0.5_Saltation.jpg"
alt="Schematic models of chromosomes ..." />

Change the window width and the image scales obligingly.

Or you could use your solo cases as intended and use your default case to specify range instructions as :

switch(n) {
    case 1 : System.out.println("case 1"); break;
    case 4 : System.out.println("case 4"); break;
    case 99 : System.out.println("case 99"); break;
    default :
        if (n >= 10 && n <= 15)
            System.out.println("10-15 range"); 
        else if (n >= 100 && n <= 200)
            System.out.println("100-200 range");
        else
            System.out.println("Your default case");
        break;   
}

"^" For the begining of the line "$" for the end of it. Eg.:

var re = /^abc$/;

Would match "abc" but not "1abc" or "abc1". You can learn more at https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/Regular_Expressions

I suspect looking at the excerpt that the function trustSrc from trustSrc(currentProject.url) is not defined in the controller.

You need to inject the $sce service in the controller and trustAsResourceUrl the url there.

In the controller:

function AppCtrl($scope, $sce) {
    // ...
    $scope.setProject = function (id) {
      $scope.currentProject = $scope.projects[id];
      $scope.currentProjectUrl = $sce.trustAsResourceUrl($scope.currentProject.url);
    }
}

In the Template:

<iframe ng-src="{{currentProjectUrl}}"> <!--content--> </iframe>

If your button is loading from an AJAX call, you should use

$(document).on("click", ".delegate_update_success", function(){
    location.reload(true);
});

instead of

$( ".delegate_update_success" ).click(function() {
    location.reload();
});

Also note the true parameter for the location.reload function.

This is unrelated to UTF-8/16 (in general, although it does convert to UTF16 and the BE/LE part can be set w/ a single line), yet below is the fastest way to convert String to byte[]. For instance: good exactly for the case provided (hash code). String.getBytes(enc) is relatively slow.

static byte[] toBytes(String s){
        byte[] b=new byte[s.length()*2];
        ByteBuffer.wrap(b).asCharBuffer().put(s);
        return b;
    }

Using the new string format to inject value into a string at placeholder {}, value is the current time.

Then rather than just displaying the raw value as {}, use formatting to obtain the correct date format.

I added the following 2 parameters: /np /nfl

So together with the 5 parameters from AndyGeek's answer, which are /njh /njs /ndl /nc /ns you get the following and it's silent:

ROBOCOPY [source] [target] /NFL /NDL /NJH /NJS /nc /ns /np

/NFL : No File List - don't log file names.
/NDL : No Directory List - don't log directory names.
/NJH : No Job Header.
/NJS : No Job Summary.
/NP  : No Progress - don't display percentage copied.
/NS  : No Size - don't log file sizes.
/NC  : No Class - don't log file classes.

I prefer using the CurrentRegion property, which is equivalent to Ctrl-*, which expands the current range to its largest continuous range with data. You start with a cell, or range, which you know will contain data, then expand it. The UsedRange Property sometimes returns huge areas, just because someone did some formatting at the bottom of the sheet.

Dim Liste As Worksheet    
Set Liste = wb.Worksheets("B Leistungen (Liste)")     
Dim longlastrow As Long
longlastrow = Liste.Range(Liste.Cells(4, 1), Liste.Cells(6, 3)).CurrentRegion.Rows.Count

Here is a shorter bit of code that reenables scroll bars across your entire website. I'm not sure if it's much different than the current most popular answer but here it is:

::-webkit-scrollbar {
    -webkit-appearance: none;
    width: 7px;
}
::-webkit-scrollbar-thumb {
    border-radius: 4px;
    background-color: rgba(0,0,0,.5);
    box-shadow: 0 0 1px rgba(255,255,255,.5);
}

Just to add on Jukka K. Korpela answer above, font awesome already defined a css selector "fa". You can simply do <i class="fa">&#xf015;</i> . The catch here is, fa defines the font-style:normal, if you need italic, you can override like <i class="fa" style="font-style:italic">&#xf015;</i>

This is because you mobile has older sdk version than your application..!!! It means your application need sdk version suppose Lollipop but you mobile has version kitkat.

Reproducing tim_yates answer on current hardware and adding leftShift() and concat() method to check the finding:

  'String leftShift' {
    foo << bar << baz
  }
  'String concat' {
    foo.concat(bar)
       .concat(baz)
       .toString()
  }

The outcome shows concat() to be the faster solution for a pure String, but if you can handle GString somewhere else, GString template is still ahead, while honorable mention should go to leftShift() (bitwise operator) and StringBuffer() with initial allocation:

BitmapRegionDecoder does the trick.

You can override onDraw(Canvas canvas), start a new Thread and decode the area visible to the user.

I know that npm install ../somelocallib works.

However, I don't know whether or not the syntax you show in the question will work from package.json...

Unfortunately, doc seems to only mention URL as a dependency.

Try file:///.../...tar.gz, pointing to a zipped local lib... and tell us if it works.

In your example, you can break the string into two pieces:

alert ( "Please Select file"
 + " to delete");

Or, when it's a string, as in your case, you can use a backslash as @Gumbo suggested:

alert ( "Please Select file\
 to delete");

Note that this backslash approach is not necessarily preferred, and possibly not universally supported (I had trouble finding hard data on this). It is not in the ECMA 5.1 spec.

When working with other code (not in quotes), line breaks are ignored, and perfectly acceptable. For example:

if(SuperLongConditionWhyIsThisSoLong
  && SuperLongConditionOnAnotherLine
  && SuperLongConditionOnThirdLineSheesh)
{
    // launch_missiles();
}

1- Select LinearLayout findViewById

LinearLayout llayout =(LinearLayout) findViewById(R.id.llayoutId); 

2- Set color from R.color.colorId

llayout.setBackgroundColor(getResources().getColor(R.color.colorId));

The best way to retrieve your public folder path from your Laravel config is the function:

$myPublicFolder = public_path();
$savePath = $mypublicPath."enter_path_to_save";
$path = $savePath."filename.ext";
return File::put($path , $data);

There is no need to have all the variables, but this is just for a demonstrative purpose.

Hope this helps, GRnGC

Here's A generic VBA Array To Range function that writes an array to the sheet in a single 'hit' to the sheet. This is much faster than writing the data into the sheet one cell at a time in loops for the rows and columns... However, there's some housekeeping to do, as you must specify the size of the target range correctly.

This 'housekeeping' looks like a lot of work and it's probably rather slow: but this is 'last mile' code to write to the sheet, and everything is faster than writing to the worksheet. Or at least, so much faster that it's effectively instantaneous, compared with a read or write to the worksheet, even in VBA, and you should do everything you possibly can in code before you hit the sheet.

A major component of this is error-trapping that I used to see turning up everywhere . I hate repetitive coding: I've coded it all here, and - hopefully - you'll never have to write it again.

A VBA 'Array to Range' function

Public Sub ArrayToRange(rngTarget As Excel.Range, InputArray As Variant)
' Write an array to an Excel range in a single 'hit' to the sheet
' InputArray must be a 2-Dimensional structure of the form Variant(Rows, Columns)

' The target range is resized automatically to the dimensions of the array, with
' the top left cell used as the start point.

' This subroutine saves repetitive coding for a common VBA and Excel task.

' If you think you won't need the code that works around common errors (long strings
' and objects in the array, etc) then feel free to comment them out.

You will need the source for ArrayDimensions:

This API declaration is required in the module header:

Private Declare Sub CopyMemory Lib "kernel32" Alias "RtlMoveMemory" _
                   (Destination As Any, _
                    Source As Any, _
                    ByVal Length As Long)

...And here's the function itself:

Private Function ArrayDimensions(arr As Variant) As Integer
  '-----------------------------------------------------------------
  ' will return:
  ' -1 if not an array
  ' 0  if an un-dimmed array
  ' 1  or more indicating the number of dimensions of a dimmed array
  '-----------------------------------------------------------------

  'get the real VarType of the argument
  'this is similar to VarType(), but returns also the VT_BYREF bit

    CopyMemory ptr, ByVal ptr, 4
  End If

  'get the address of the SAFEARRAY structure
  'this is stored in the descriptor

  'get the first word of the SAFEARRAY structure

  '...but first check that saAddr is non-zero, otherwise
  'this routine bombs when the array is uninitialized

  If ptr Then
    CopyMemory ArrayDimensions, ByVal ptr, 2
  End If

End Function

Also: I would advise you to keep that declaration private. If you must make it a public Sub in another module, insert the Option Private Module statement in the module header. You really don't want your users calling any function with CopyMemoryoperations and pointer arithmetic.

$('b').contents().unwrap();

This selects all <b> elements, then uses .contents() to target the text content of the <b>, then .unwrap() to remove its parent <b> element.

For the greatest performance, always go native:

var b = document.getElementsByTagName('b');

while(b.length) {
    var parent = b[ 0 ].parentNode;
    while( b[ 0 ].firstChild ) {
        parent.insertBefore(  b[ 0 ].firstChild, b[ 0 ] );
    }
     parent.removeChild( b[ 0 ] );
}

This will be much faster than any jQuery solution provided here.

Your email session should be provided an authenticator instance as below

Session session = Session.getDefaultInstance(props,
    new Authenticator() {
        protected PasswordAuthentication  getPasswordAuthentication() {
        return new PasswordAuthentication(
                    "[email protected]", "password");
                }
    });

SELECT DATECOL - DATEPART(weekday, DATECOL), DATECOL - DATEPART(weekday, DATECOL) + 7

Invoking an empty time.Time struct literal will return Go's zero date. Thus, for the following print statement:

fmt.Println(time.Time{})

The output is:

0001-01-01 00:00:00 +0000 UTC

For the sake of completeness, the official documentation explicitly states:

The zero value of type Time is January 1, year 1, 00:00:00.000000000 UTC.

Map

You could create a Hashmap<String, Object> using one of the values as a key, and then seeing if yourHashMap.keySet().contains(yourValue) returns true.

Try this,

element.style {
    background: rgba(0, 0, 0, 0) url("img/shopping_bgImg.jpg") no-repeat scroll center center / cover;
}

In the page tag:

<%@ page import="java.util.List" %>

You can also define a custom theme that is derived from your base theme:

<android.support.design.widget.NavigationView
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        android:id="@+id/nav_view"
        app:headerLayout="@layout/nav_view_header"
        app:menu="@layout/nav_view_menu"
        app:theme="@style/MyTheme.NavMenu" />

and then in your styles.xml file:

  <style name="MyTheme.NavMenu" parent="MyTheme.Base">
    <item name="android:textColorPrimary">@color/yourcolor</item>
  </style>

you can also apply more attributes to the custom theme.

cin.get() seems to flush it automatically oddly enough (probably not preferred though, since this is confusing and probably temperamental).

Update for Java 8 or plus. In Java 8, PermGen (Permanent Generation) space is removed and replaced by Meta Space. The String pool memory is moved to the heap of JVM.

Compared with Java 7, the String pool size is increased in the heap. Therefore, you have more space for internalized Strings, but you have less memory for the whole application.

One more thing, you have already known that when comparing 2 (referrences of) objects in Java, '==' is used for comparing the reference of object, 'equals' is used for comparing the contents of object.

Let's check this code:

String value1 = "70";
String value2 = "70";
String value3 = new Integer(70).toString();

Result:

value1 == value2 ---> true

value1 == value3 ---> false

value1.equals(value3) ---> true

value1 == value3.intern() ---> true

That's why you should use 'equals' to compare 2 String objects. And that's is how intern() is useful.

use ProgressDialog.

ProgressDialog dialog=new ProgressDialog(context);
dialog.setMessage("message");
dialog.setCancelable(false);
dialog.setInverseBackgroundForced(false);
dialog.show();

hide it whenever your UI is ready with data. call :

dialog.hide();

Views can:

• Simplify a complex table structure
• Simplify your security model by allowing you to filter sensitive data and assign permissions in a simpler fashion
• Allow you to change the logic and behavior without changing the output structure (the output remains the same but the underlying SELECT could change significantly)
• Increase performance (Sql Server Indexed Views)
• Offer specific query optimization with the view that might be difficult to glean otherwise

And you should not design tables to match views. Your base model should concern itself with efficient storage and retrieval of the data. Views are partly a tool that mitigates the complexities that arise from an efficient, normalized model by allowing you to abstract that complexity.

Also, asking "what are the advantages of using a view over a table? " is not a great comparison. You can't go without tables, but you can do without views. They each exist for a very different reason. Tables are the concrete model and Views are an abstracted, well, View.

Quick fix:

position: relative;
top: -12px;
left: -2px;

this should balance out those offsets, but maybe you should take a look at your whole layout and see how that box interacts with other boxes.

As for terminology, left, right, top and bottom are CSS offset properties. They are used for positioning elements at a specific location (when used with absolute or fixed positioning), or to move them relative to their default location (when used with relative positioning). Margins on the other hand specify gaps between boxes and they sometimes collapse, so they can't be reliably used as offsets.

But note that in your case that offset may not be computed (solely) from CSS offsets.

Once you have cloned the repo, you have everything: you can then hg up branchname or hg up tagname to update your working copy.

UP: hg up is a shortcut of hg update, which also has hg checkout alias for people with git habits.

select constraint_name,constraint_type 
from user_constraints
where table_name = 'YOUR TABLE NAME';

note: table name should be in caps.

In case you don't know the name of the table then,

select constraint_name,constraint_type,table_name 
from user_constraints;

You can use the following registry location to check if computer is running 32 or 64 bit of Windows operating system:

HKLM\HARDWARE\DESCRIPTION\System\CentralProcessor\0

You will see the following registry entries in the right pane:

Identifier     REG_SZ             x86 Family 6 Model 14 Stepping 12
Platform ID    REG_DWORD          0x00000020(32)

The above x86 and 0x00000020(32) indicate that the operating system version is 32 bit.

You have to use square bracket notation when -

1. The property name is number.

   var ob = {
     1: 'One',
     7 : 'Seven'
   }
   ob.7  // SyntaxError
   ob[7] // "Seven"
   

2. The property name has special character.

   var ob = {
     'This is one': 1,
     'This is seven': 7,
   }  
   ob.'This is one'  // SyntaxError
   ob['This is one'] // 1
   

3. The property name is assigned to a variable and you want to access the property value by this variable.

   var ob = {
     'One': 1,
     'Seven': 7,
   }
   
   var _Seven = 'Seven';
   ob._Seven  // undefined
   ob[_Seven] // 7
   

Take a look at Blaze-Persistence Entity Views which works on top of JPA and provides first class DTO support. You can project anything to attributes within Entity Views and it will even reuse existing join nodes for associations if possible.

Here is an example mapping

@EntityView(Order.class)
interface OrderSummary {
  Integer getId();
  @Mapping("SUM(orderPositions.price * orderPositions.amount * orderPositions.tax)")
  BigDecimal getOrderAmount();
  @Mapping("COUNT(orderPositions)")
  Long getItemCount();
}

Fetching this will generate a JPQL/HQL query similar to this

SELECT
  o.id,
  SUM(p.price * p.amount * p.tax),
  COUNT(p.id)
FROM
  Order o
LEFT JOIN
  o.orderPositions p
GROUP BY
  o.id

Here is a blog post about custom subquery providers which might be interesting to you as well: https://blazebit.com/blog/2017/entity-view-mapping-subqueries.html

My mistake, the resource files WERE actually copied to target/test-classes. The problem seemed to be due to spaces in my project name, e.g. Project%20Name.

I'm now loading the file as follows and it works:

org.apache.commons.io.FileUtils.toFile(myClass().getResource("resourceFile.txt")??);

Or, (taken from Java: how to get a File from an escaped URL?) this may be better (no dependency on Apache Commons):

myClass().getResource("resourceFile.txt")??.toURI();

Remember that Constructor of an object is called immediately after the memory is allocated for that object and whereas the destructor is called just before deallocating the memory of that object.

In my particular case -g -march=armv7-a -mfloat-abi=hard -mfpu=neon -marm -mthumb-interwork worked.

You need to use convert in order by as well:

SELECT  Convert(varchar,A.InsertDate,103) as Tran_Date
order by Convert(varchar,A.InsertDate,103)

Recently the CAB-forum (*) decided that

All certificates containing an underscore character in any dNSName entry and having a validity period of more than 30 days MUST be revoked prior to January 15, 2019. https://cabforum.org/2018/11/12/ballot-sc-12-sunset-of-underscores-in-dnsnames/

This means that you are no longer allowed to use underscores in domains that will have a ssl/tls certificate.

(*) The Certification Authority Browser Forum (CA/Browser Forum) is a voluntary gathering of leading Certificate Issuers (as defined in Section 2.1(a)(1) and (2) below) and vendors of Internet browser software and other applications that use certificates (Certificate Consumers, as defined in Section 2.1(a)(3) below).

d* means that it should match zero or more "d" characters. So any string is a valid match. Try d+ instead!

In order to have support for wildcard patterns I would replace the wildcards with the RegEx equivalents. Like * becomes .* and ? becomes .?. Then your expression above becomes d.*

I think we can modify the UsedRange code from @Readify's answer above to get the last used column even if the starting columns are blank or not.

So this lColumn = ws.UsedRange.Columns.Count modified to

this lColumn = ws.UsedRange.Column + ws.UsedRange.Columns.Count - 1 will give reliable results always

?Sheet1.UsedRange.Column + Sheet1.UsedRange.Columns.Count - 1

Above line Yields 9 in the immediate window.

It creates an interpolated string.

From MSDN

Used to construct strings. An interpolated string expression looks like a template string that contains expressions. An interpolated string expression creates a string by replacing the contained expressions with the ToString represenations of the expressions’ results.

ex :

 var name = "Sam";
 var msg = $"hello, {name}";

 Console.WriteLine(msg); // hello, Sam

You can use expressions within the interpolated string

 var msg = $"hello, {name.ToLower()}";
 Console.WriteLine(msg); // hello, sam

The nice thing about it is that you don't need to worry about the order of parameters as you do with String.Format.

  var s = String.Format("{0},{1},{2}...{88}",p0,p1,..,p88);

Now if you want to remove some parameters you have to go and update all the counts, which is not the case anymore.

Note that the good old string.format is still relevant if you want to specify cultural info in your formatting.

From http://en.wikipedia.org/wiki/CDATA:

Since it is useful to be able to use less-than signs (<) and ampersands (&) in web page scripts, and to a lesser extent styles, without having to remember to escape them, it is common to use CDATA markers around the text of inline and elements in XHTML documents. But so that the document can also be parsed by HTML parsers, which do not recognise the CDATA markers, the CDATA markers are usually commented-out, as in this JavaScript example:

<script type="text/javascript">
//<![CDATA[
document.write("<");
//]]>
</script>

It's called an initialization list. It initializes members before the body of the constructor executes.

It's not directly relevant but I came here searching for a one liner for merging nested objects such as

const nodes = {
    node1: {
        interfaces: {if1: {}, if2: {}}
    },
    node2: {
        interfaces: {if3: {}, if4: {}}
    },
    node3: {
        interfaces: {if5: {}, if6: {}}
    },
}

The solution is to use a combination of reduce and object spread:

const allInterfaces = nodes => Object.keys(nodes).reduce((res, key) => ({...res, ...nodes[key].interfaces}), {})

Make all parent element with 100% width and 100% height and use display: table; and display:table-cell;, check the working sample.

Working Git Version

<!DOCTYPE html>
<html>
<head>
<style>
html,body{height: 100%;}
body{width: 100%;}

</head>
<body style="display: table; background-color: #ff0000; ">

</body>
</html>

I don't have IE8 to test this out, but I'm pretty sure it should work:

<div class="screen">
   <!-- code -->
   <div class="innerdiv">
      text or other content
   </div>
</div>

and the css:

.screen{
position: relative;
}
.innerdiv {
position: absolute;
bottom: 0;
right: 0;
}

This should place the .innerdiv in the bottom-right corner of the .screen class. I hope this helps :)

Following solution worked for me

First you need to add this registry key

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\SideBySide\PreferExternalManifest (DWORD) to 1

Next, a manifest file with the same name as the executable must be present in the same folder as the executable. The file is named eclipse.exe.manifest and consists of:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0" xmlns:asmv3="urn:schemas-microsoft-com:asm.v3">

    <trustInfo xmlns="urn:schemas-microsoft-com:asm.v2">
        <security>
            <requestedPrivileges>
                <requestedExecutionLevel xmlns:ms_asmv3="urn:schemas-microsoft-com:asm.v3"
                               level="asInvoker"
                               ms_asmv3:uiAccess="false">
                </requestedExecutionLevel>
            </requestedPrivileges>
        </security>
    </trustInfo>
    <asmv3:application>

        </asmv3:windowsSettings>
    </asmv3:application>

The alert() dialog is not rendered in HTML, and thus the HTML you have embedded is meaningless.

You'd need to use a custom modal to achieve that.

Rextester Demo

Example of export in file with full path on Windows and in case your file has headers:

df.to_csv (r'C:\Users\John\Desktop\export_dataframe.csv', index = None, header=True) 

For example, if you want to store the file in same directory where your script is, with utf-8 encoding and tab as separator:

df.to_csv(r'./export/dftocsv.csv', sep='\t', encoding='utf-8', header='true')

Login in with System Admin User Account and execute below SQL Procedure.

begin
dbms_xdb.sethttpport('Your Port Number');
end;

Then open the Browser and access the below URL

http://127.0.0.1:YourPortNumber/apex/

You could also execute tree > tree.txt in both folders and then diff both tree.txt files with any file based diff tool (git diff).

Binding = your textual representation of a specific column gets mapped to a physical column in some table, in some database, on some server.

Multipart identifier could be: MyDatabase.dbo.MyTable. If you get any of these identifiers wrong, then you have a multipart identifier that cannot be mapped.

The best way to avoid it is to write the query right the first time, or use a plugin for management studio that provides intellisense and thus help you out by avoiding typos.

Pay attention that in http.Request header "Host" can not be set via Set method

req.Header.Set("Host", "domain.tld")

but can be set directly:

req.Host = "domain.tld":

req, err := http.NewRequest("GET", "http://10.0.0.1/", nil)
if err != nil {
    ...
}

req.Host = "domain.tld"
client := &http.Client{}
resp, err := client.Do(req)

If you are using an old version of FFMPEG and you cant upgrade you can do the following:

ffmpeg -i PATH/VIDEO_FILE_NAME.mp4 -i PATH/AUDIO_FILE_NAME.mp3 -vcodec copy -shortest DESTINATION_PATH/NEW_VIDEO_FILE_NAME.mp4

Notice that I used -vcodec

Use:

#!/bin/bash

s1="hi"
s2="hi"

if [ "x$s1" == "x$s2" ]
then
  echo match
fi

Adding an additional string inside makes it more safe.

You could also use another notation for single-line commands:

[ "x$s1" == "x$s2" ] && echo match

To pass arguments to the jar:

java -jar myjar.jar one two

You can access them in the main() method of "Main-Class" (mentioned in the manifest.mf file of a JAR).

String one = args[0];  
String two = args[1];  

I wouldn't reference the parent directly in the child objects. In my opinion the childs shouldn't know anything about the parents. This will limits the flexibility!

I would solve this with events/handlers.

public class Meter
{
    private int _powerRating = 0;
    private Production _production;

    public Meter()
    {
        _production = new Production();
        _production.OnRequestPowerRating += new Func<int>(delegate { return _powerRating; });
        _production.DoSomething();
    }
}

public class Production
{
    protected int RequestPowerRating()
    {
        if (OnRequestPowerRating == null)
            throw new Exception("OnRequestPowerRating handler is not assigned");

        return OnRequestPowerRating();
    }

    public void DoSomething()
    {
        int powerRating = RequestPowerRating();
        Debug.WriteLine("The parents powerrating is :" + powerRating);

    }

    public Func<int> OnRequestPowerRating;
}

In this case I solved it with the Func<> generic, but can be done with 'normal' functions. This why the child(Production) is totally independent from it's parent(Meter).

But! If there are too many events/handlers or you just want to pass a parent object, i would solve it with an interface:

public interface IMeter
{
    int PowerRating { get; }
}

public class Meter : IMeter
{
    private int _powerRating = 0;
    private Production _production;

    public Meter()
    {
        _production = new Production(this);
        _production.DoSomething();
    }

    public int PowerRating { get { return _powerRating; } }
}

public class Production
{
    private IMeter _meter;

    public Production(IMeter meter)
    {
        _meter = meter;
    }

    public void DoSomething()
    {
        Debug.WriteLine("The parents powerrating is :" + _meter.PowerRating);
    }
}

This looks pretty much the same as the solution mentions, but the interface could be defined in another assembly and can be implemented by more than 1 class.

Ended up writing this today and seems to be ok. Your usage could be:

await TaskEx.WaitUntil(isExcelInteractive);

code (including the inverse operation)

public static class TaskEx
{
    /// <summary>
    /// Blocks while condition is true or timeout occurs.
    /// </summary>
    /// <param name="condition">The condition that will perpetuate the block.</param>
    /// <param name="frequency">The frequency at which the condition will be check, in milliseconds.</param>
    /// <param name="timeout">Timeout in milliseconds.</param>
    /// <exception cref="TimeoutException"></exception>
    /// <returns></returns>
    public static async Task WaitWhile(Func<bool> condition, int frequency = 25, int timeout = -1)
    {
        var waitTask = Task.Run(async () =>
        {
            while (condition()) await Task.Delay(frequency);
        });

        if(waitTask != await Task.WhenAny(waitTask, Task.Delay(timeout)))
            throw new TimeoutException();
    }

For large dataframes of numeric data, you may see a significant performance improvement via numpy.lexsort, which performs an indirect sort using a sequence of keys:

import pandas as pd
import numpy as np

np.random.seed(0)

df1 = pd.DataFrame(np.random.randint(1, 5, (10,2)), columns=['a','b'])
df1 = pd.concat([df1]*100000)

def pdsort(df1):
    return df1.sort_values(['a', 'b'], ascending=[True, False])

def lex(df1):
    arr = df1.values
    return pd.DataFrame(arr[np.lexsort((-arr[:, 1], arr[:, 0]))])

assert (pdsort(df1).values == lex(df1).values).all()

%timeit pdsort(df1)  # 193 ms per loop
%timeit lex(df1)     # 143 ms per loop

One peculiarity is that the defined sorting order with numpy.lexsort is reversed: (-'b', 'a') sorts by series a first. We negate series b to reflect we want this series in descending order.

Be aware that np.lexsort only sorts with numeric values, while pd.DataFrame.sort_values works with either string or numeric values. Using np.lexsort with strings will give: TypeError: bad operand type for unary -: 'str'.

Natural verses artifical keys is a kind of religious debate among the database community - see this article and others it links to. I'm neither in favour of always having artifical keys, nor of never having them. I would decide on a case-by-case basis, for example:

• US States: I'd go for state_code ('TX' for Texas etc.), rather than state_id=1 for Texas
• Employees: I'd usually create an artifical employee_id, because it's hard to find anything else that works. SSN or equivalent may work, but there could be issues like a new joiner who hasn't supplied his/her SSN yet.
• Employee Salary History: (employee_id, start_date). I would not create an artifical employee_salary_history_id. What point would it serve (other than "foolish consistency")

Wherever artificial keys are used, you should always also declare unique constraints on the natural keys. For example, use state_id if you must, but then you'd better declare a unique constraint on state_code, otherwise you are sure to eventually end up with:

state_id    state_code   state_name
137         TX           Texas
...         ...          ...
249         TX           Texas

You might want to look into open2 and open3 in case you need bidirectional communication.

The real question is, what do you intend to use the size for?

Your first problem is that there are at least four definitions for "file size":

• The "end of file" offset, which is the number of bytes you have to skip to go from the beginning to the end of the file.
  In other words, it is the number of bytes logically in the file (from a usage perspective).

• The "valid data length", which is equal to the offset of the first byte which is not actually stored.
  This is always less than or equal to the "end of file", and is a multiple of the cluster size.
  For example, a 1 GB file can have a valid data length of 1 MB. If you ask Windows to read the first 8 MB, it will read the first 1 MB and pretend the rest of the data was there, returning it as zeros.

• The "allocated size" of a file. This is always greater than or equal to the "end of file".
  This is the number of clusters that the OS has allocated for the file, multiplied by the cluster size.
  Unlike the case where the "end of file" is greater than the "valid data length", The excess bytes are not considered to be part of the file's data, so the OS will not fill a buffer with zeros if you try to read in the allocated region beyond the end of the file.

• The "compressed size" of a file, which is only valid for compressed (and sparse?) files.
  It is equal to the size of a cluster, multiplied by the number of clusters on the volume that are actually allocated to this file.
  For non-compressed and non-sparse files, there is no notion of "compressed size"; you would use the "allocated size" instead.

Your second problem is that a "file" like C:\Foo can actually have multiple streams of data.
This name just refers to the default stream. A file might have alternate streams, like C:\Foo:Bar, whose size is not even shown in Explorer!

Your third problem is that a "file" can have multiple names ("hard links").
For example, C:\Windows\notepad.exe and C:\Windows\System32\notepad.exe are two names for the same file. Any name can be used to open any stream of the file.

Your fourth problem is that a "file" (or directory) might in fact not even be a file (or directory):
It might be a soft link (a "symbolic link" or a "reparse point") to some other file (or directory).
That other file might not even be on the same drive. It might even point to something on the network, or it might even be recursive! Should the size be infinity if it's recursive?

Your fifth is that there are "filter" drivers that make certain files or directories look like actual files or directories, even though they aren't. For example, Microsoft's WIM image files (which are compressed) can be "mounted" on a folder using a tool called ImageX, and those do not look like reparse points or links. They look just like directories -- except that the're not actually directories, and the notion of "size" doesn't really make sense for them.

Your sixth problem is that every file requires metadata.
For example, having 10 names for the same file requires more metadata, which requires space. If the file names are short, having 10 names might be as cheap as having 1 name -- and if they're long, then having multiple names can use more disk space for the metadata. (Same story with multiple streams, etc.)
Do you count these, too?

There's a few options. array_shift() will return the first element, but it will also remove the first element from the array.

$first = array_shift($array);

current() will return the value of the array that its internal memory pointer is pointing to, which is the first element by default.

$first = current($array);

If you want to make sure that it is pointing to the first element, you can always use reset().

reset($array);
$first = current($array);

A way to use INSERT and WHERE is

INSERT INTO MYTABLE SELECT 953,'Hello',43 WHERE 0 in (SELECT count(*) FROM MYTABLE WHERE myID=953); In this case ist like an exist-test. There is no exception if you run it two or more times...

I try to @Chumillas's answer and @chhameed's answer, but it not work,because the sql is wrong.So I found new approach,like this:

• Insert echo $sql; flush(); exit; into before return $sql; _compile_select function of DB_active_rec.php

The size of storage required and how big the numbers can be.

On SQL Server:

• tinyint 1 byte, 0 to 255
• smallint 2 bytes, -2¹⁵ (-32,768) to 2^15-1 (32,767)
• int 4 bytes, -2³¹ (-2,147,483,648) to 2^31-1 (2,147,483,647)
• bigint 8 bytes, -2⁶³ (-9,223,372,036,854,775,808) to 2^63-1 (9,223,372,036,854,775,807)

You can store the number 1 in all 4, but a bigint will use 8 bytes, while a tinyint will use 1 byte.

If the dataset is called data, then all the rows meeting a condition where value of column 'pm2.5' > 300 can be received by -

data[data['pm2.5'] >300,]

It's a modulo operation http://en.wikipedia.org/wiki/Modulo_operation

http://docs.python.org/reference/expressions.html

So with order of operations, that works out to

(3+2+1-5) + (4%2) - (1/4) + 6

(1) + (0) - (0) + 6

7

The 1/4=0 because we're doing integer math here.

In Visual Studio 2015 (this still holds in 2019 for the same value), check the setting:

Tools > Options > Environment > Documents > Check for consistent line endings on load

VS2015 will now prompt you to convert line endings when you open a file where they are inconsistent, so all you need to do is open the files, select the desired option from the prompt and save them again.

All the answers provided here uses normal function but these days most of our code uses arrow functions in ES6. I hope my answer will help readers on how to use arrow function when we do iteration over array of objects

let data = {
      "messages": [{
           "msgFrom": "13223821242",
           "msgBody": "Hi there"
       }, {
          "msgFrom": "Bill",
          "msgBody": "Hello!"
       }]
 }

Do .forEach on array using arrow function

 data.messages.forEach((obj, i) => {
     console.log("msgFrom", obj.msgFrom);
     console.log("msgBody", obj.msgBody);
 });

Do .map on array using arrow function

 data.messages.map((obj, i) => {
     console.log("msgFrom", obj.msgFrom);
     console.log("msgBody", obj.msgBody);
 });

First you need to allocate an array of the combined length, then use arraycopy to fill it from both sources.

byte[] ciphertext = blah;
byte[] mac = blah;
byte[] out = new byte[ciphertext.length + mac.length];


System.arraycopy(ciphertext, 0, out, 0, ciphertext.length);
System.arraycopy(mac, 0, out, ciphertext.length, mac.length);

For Nginx, the only thing that worked for me was adding this header:

add_header 'Access-Control-Allow-Headers' 'Authorization,Content-Type,Accept,Origin,User-Agent,DNT,Cache-Control,X-Mx-ReqToken,Keep-Alive,X-Requested-With,If-Modified-Since';

Along with the Access-Control-Allow-Origin header:

add_header 'Access-Control-Allow-Origin' '*';

Then reloaded the nginx config and it worked great. Credit https://gist.github.com/algal/5480916.

Possibly:

select lpad(column, 8, 0) from table;

Edited in response to question from mylesg, in comments below:

ok, seems to make the change on the query- but how do I make it stick (change it) permanently in the table? I tried an UPDATE instead of SELECT

I'm assuming that you used a query similar to:

UPDATE table SET columnName=lpad(nums,8,0);

If that was successful, but the table's values are still without leading-zeroes, then I'd suggest you probably set the column as a numeric type? If that's the case then you'd need to alter the table so that the column is of a text/varchar() type in order to preserve the leading zeroes:

First:

ALTER TABLE `table` CHANGE `numberColumn` `numberColumn` CHAR(8);

Second, run the update:

UPDATE table SET `numberColumn`=LPAD(`numberColum`, 8, '0');

This should, then, preserve the leading-zeroes; the down-side is that the column is no longer strictly of a numeric type; so you may have to enforce more strict validation (depending on your use-case) to ensure that non-numerals aren't entered into that column.

For working with UTC timezones:

time_stamp = calendar.timegm(dt.timetuple())

datetime.utcfromtimestamp(time_stamp)

Remove SQL_MODE to TRADITIONAL in the preferences panel.

I assume entropy was mentioned in the context of building decision trees.

To illustrate, imagine the task of learning to classify first-names into male/female groups. That is given a list of names each labeled with either m or f, we want to learn a model that fits the data and can be used to predict the gender of a new unseen first-name.

name       gender
-----------------        Now we want to predict 
Ashley        f              the gender of "Amro" (my name)
Brian         m
Caroline      f
David         m

First step is deciding what features of the data are relevant to the target class we want to predict. Some example features include: first/last letter, length, number of vowels, does it end with a vowel, etc.. So after feature extraction, our data looks like:

# name    ends-vowel  num-vowels   length   gender
# ------------------------------------------------
Ashley        1         3           6        f
Brian         0         2           5        m
Caroline      1         4           8        f
David         0         2           5        m

The goal is to build a decision tree. An example of a tree would be:

length<7
|   num-vowels<3: male
|   num-vowels>=3
|   |   ends-vowel=1: female
|   |   ends-vowel=0: male
length>=7
|   length=5: male

basically each node represent a test performed on a single attribute, and we go left or right depending on the result of the test. We keep traversing the tree until we reach a leaf node which contains the class prediction (m or f)

So if we run the name Amro down this tree, we start by testing "is the length<7?" and the answer is yes, so we go down that branch. Following the branch, the next test "is the number of vowels<3?" again evaluates to true. This leads to a leaf node labeled m, and thus the prediction is male (which I happen to be, so the tree predicted the outcome correctly).

The decision tree is built in a top-down fashion, but the question is how do you choose which attribute to split at each node? The answer is find the feature that best splits the target class into the purest possible children nodes (ie: nodes that don't contain a mix of both male and female, rather pure nodes with only one class).

This measure of purity is called the information. It represents the expected amount of information that would be needed to specify whether a new instance (first-name) should be classified male or female, given the example that reached the node. We calculate it based on the number of male and female classes at the node.

Entropy on the other hand is a measure of impurity (the opposite). It is defined for a binary class with values a/b as:

Entropy = - p(a)*log(p(a)) - p(b)*log(p(b))

This binary entropy function is depicted in the figure below (random variable can take one of two values). It reaches its maximum when the probability is p=1/2, meaning that p(X=a)=0.5 or similarlyp(X=b)=0.5 having a 50%/50% chance of being either a or b (uncertainty is at a maximum). The entropy function is at zero minimum when probability is p=1 or p=0 with complete certainty (p(X=a)=1 or p(X=a)=0 respectively, latter implies p(X=b)=1).

Of course the definition of entropy can be generalized for a discrete random variable X with N outcomes (not just two):

(the log in the formula is usually taken as the logarithm to the base 2)

Back to our task of name classification, lets look at an example. Imagine at some point during the process of constructing the tree, we were considering the following split:

     ends-vowel
      [9m,5f]          <--- the [..,..] notation represents the class
    /          \            distribution of instances that reached a node
   =1          =0
 -------     -------
 [3m,4f]     [6m,1f]

As you can see, before the split we had 9 males and 5 females, i.e. P(m)=9/14 and P(f)=5/14. According to the definition of entropy:

Entropy_before = - (5/14)*log2(5/14) - (9/14)*log2(9/14) = 0.9403

Next we compare it with the entropy computed after considering the split by looking at two child branches. In the left branch of ends-vowel=1, we have:

Entropy_left = - (3/7)*log2(3/7) - (4/7)*log2(4/7) = 0.9852

and the right branch of ends-vowel=0, we have:

Entropy_right = - (6/7)*log2(6/7) - (1/7)*log2(1/7) = 0.5917

We combine the left/right entropies using the number of instances down each branch as weight factor (7 instances went left, and 7 instances went right), and get the final entropy after the split:

Entropy_after = 7/14*Entropy_left + 7/14*Entropy_right = 0.7885

Now by comparing the entropy before and after the split, we obtain a measure of information gain, or how much information we gained by doing the split using that particular feature:

Information_Gain = Entropy_before - Entropy_after = 0.1518

You can interpret the above calculation as following: by doing the split with the end-vowels feature, we were able to reduce uncertainty in the sub-tree prediction outcome by a small amount of 0.1518 (measured in bits as units of information).

At each node of the tree, this calculation is performed for every feature, and the feature with the largest information gain is chosen for the split in a greedy manner (thus favoring features that produce pure splits with low uncertainty/entropy). This process is applied recursively from the root-node down, and stops when a leaf node contains instances all having the same class (no need to split it further).

Note that I skipped over some details which are beyond the scope of this post, including how to handle numeric features, missing values, overfitting and pruning trees, etc..

Update:

MongoServer.Create is obsolete now (thanks to @aknuds1). Instead this use following code:

var _server = new MongoClient(connectionString).GetServer();

It's easy. You should first take database name from connection string and then get database by name. Complete example:

var connectionString = "mongodb://localhost:27020/mydb";

//take database name from connection string
var _databaseName = MongoUrl.Create(connectionString).DatabaseName;
var _server = MongoServer.Create(connectionString);

//and then get database by database name:
_server.GetDatabase(_databaseName);

Important: If your database and auth database are different, you can add a authSource= query parameter to specify a different auth database. (thank you to @chrisdrobison)

From docs:

NOTE If you are using the database segment as the initial database to use, but the username and password specified are defined in a different database, you can use the authSource option to specify the database in which the credential is defined. For example, mongodb://user:pass@hostname/db1?authSource=userDb would authenticate the credential against the userDb database instead of db1.

You can use the visible selector:

http://api.jquery.com/visible-selector/

//For proper line spacing

NSString *text1 = @"Hello";
NSString *text2 = @"\nWorld";
UIFont *text1Font = [UIFont fontWithName:@"HelveticaNeue-Medium" size:10];
NSMutableAttributedString *attributedString1 =
[[NSMutableAttributedString alloc] initWithString:text1 attributes:@{ NSFontAttributeName : text1Font }];
NSMutableParagraphStyle *paragraphStyle1 = [[NSMutableParagraphStyle alloc] init];
[paragraphStyle1 setAlignment:NSTextAlignmentCenter];
[paragraphStyle1 setLineSpacing:4];
[attributedString1 addAttribute:NSParagraphStyleAttributeName value:paragraphStyle1 range:NSMakeRange(0, [attributedString1 length])];

UIFont *text2Font = [UIFont fontWithName:@"HelveticaNeue-Medium" size:16];
NSMutableAttributedString *attributedString2 =
[[NSMutableAttributedString alloc] initWithString:text2 attributes:@{NSFontAttributeName : text2Font }];
NSMutableParagraphStyle *paragraphStyle2 = [[NSMutableParagraphStyle alloc] init];
[paragraphStyle2 setLineSpacing:4];
[paragraphStyle2 setAlignment:NSTextAlignmentCenter];
[attributedString2 addAttribute:NSParagraphStyleAttributeName value:paragraphStyle2 range:NSMakeRange(0, [attributedString2 length])];

[attributedString1 appendAttributedString:attributedString2];

I recently had a similar issue with SourceTree: any time I tried to push/pull/fetch to/from the remote origin I would get an authentication error (using SourceTree with Stash). Sometimes I would be challenge in Stash with a CAPTCHA but it never made a difference if I provided the correct information or not.

For me, we're using SourceTree and Stash in a corporate environment; user accounts are based on network credentials. Part of our network security requires us to change those passwords on a regular basis.

I was operating under the assumption that SourceTree/Stash was "aware" of any change made to my network password. But apparently -- at least in this instance -- it was not.

To fix, all I needed to do was:

Tools > Options > Authentication > Edit (Edit Password)

I set the password to match my current network password and everything began working as expected.

Not sure if this helps the OP but I hope it may help someone else looking for answers to a similar issue.

In IntelliJ IDEA this happened to me when I imported a project that had been working fine and running with Java 1.7. I apparently hadn't notified IntelliJ that java 1.7 had been installed on my machine, and it wasn't finding my $JAVA_HOME.

On a Mac, this is resolved by:

Right clicking on the module | Module Settings | Project

and adding the 1.7 SDK by selecting "New" in the Project SDK.

Then go to the main IntelliJ IDEA menu | Preferences | Maven | Runner

and select the correct JRE. In my case it updated correctly Use Project SDK, which was now 1.7.

Avoiding non-standard module (seems to be a missing method of datetime module):

from datetime import datetime
utcOffset_min = int(round((datetime.now() - datetime.utcnow()).total_seconds())) / 60   # round for taking time twice
utcOffset_h = utcOffset_min / 60
assert(utcOffset_min == utcOffset_h * 60)   # we do not handle 1/2 h timezone offsets

print 'Local time offset is %i h to UTC.' % (utcOffset_h)

I'm running into the same issue with one of my own apps. So far I've found the only non-deprecated way to access Google News data is through their RSS feeds. They have a feed for each section and also a useful search function. However, these are only for noncommercial use.

As for viable alternatives I'll be trying out these two services: Feedzilla, Daylife

The rest of the sentence is:

where only structure (e.g., elements, comments, processing instructions, CDATA sections, and entity references) separates Text nodes, i.e., there are neither adjacent Text nodes nor empty Text nodes.

This basically means that the following XML element

<foo>hello 
wor
ld</foo>

could be represented like this in a denormalized node:

Element foo
    Text node: ""
    Text node: "Hello "
    Text node: "wor"
    Text node: "ld"

When normalized, the node will look like this

Element foo
    Text node: "Hello world"

And the same goes for attributes: <foo bar="Hello world"/>, comments, etc.

The for loop is definitely more pythonic, as it uses Python's higher level built in functionality to convey what you're doing both more clearly and concisely. The overhead of range vs xrange, and assigning an unused i variable, stem from the absence of a statement like Verilog's repeat statement. The main reason to stick to the for range solution is that other ways are more complex. For instance:

from itertools import repeat

for unused in repeat(None, 10):
    del unused   # redundant and inefficient, the name is clear enough
    print "This is run 10 times"

Using repeat instead of range here is less clear because it's not as well known a function, and more complex because you need to import it. The main style guides if you need a reference are PEP 20 - The Zen of Python and PEP 8 - Style Guide for Python Code.

We also note that the for range version is an explicit example used in both the language reference and tutorial, although in that case the value is used. It does mean the form is bound to be more familiar than the while expansion of a C-style for loop.

I found I needed to enable the SSL module in Apache (obviously prefix commands with sudo if you are not running as root):

a2enmod ssl

then restart Apache:

/etc/init.d/apache2 restart

More details of SSL in Apache for Ubuntu / Debian here.

Same technique as the accepted answer, but with HTTPS support, and more readable:

$current_url = sprintf(
    '%s://%s/%s',
    isset($_SERVER['HTTPS']) ? 'https' : 'http',
    $_SERVER['HTTP_HOST'],
    $_SERVER['REQUEST_URI']
);

I find neither http.proxy nor GIT_PROXY_COMMAND work for my authenticated http proxy. The proxy is not triggered in either way. But I find a way to work around this.

1. Install corkscrew, or other alternatives you want.

2. Create a authfile. The format for authfile is: user_name:password, and user_name, password is your username and password to access your proxy. To create such a file, simply run command like this: echo "username:password" > ~/.ssh/authfile.

3. Edit ~/.ssh/config, and make sure its permission is 644: chmod 644 ~/.ssh/config

Take github.com as an example, add the following lines to ~/.ssh/config:

Host    github.com
        HostName        github.com
        ProxyCommand    /usr/local/bin/corkscrew <your.proxy> <proxy port> %h %p <path/to/authfile>
        User            git

Now whenever you do anything with [email protected], it will use the proxy automatically. You can easily do the same thing to Bitbucket as well.

This is not so elegant as other approaches, but it works like a charm.

EDIT: CodePen example

For AngularJS, I defined the following directive:

module.directive('isolateScrolling', function () {
  return {
    restrict: 'A',
      link: function (scope, element, attr) {
        element.bind('DOMMouseScroll', function (e) {
          if (e.detail > 0 && this.clientHeight + this.scrollTop == this.scrollHeight) {
            this.scrollTop = this.scrollHeight - this.clientHeight;
            e.stopPropagation();
            e.preventDefault();
            return false;
          }
          else if (e.detail < 0 && this.scrollTop <= 0) {
            this.scrollTop = 0;
            e.stopPropagation();
            e.preventDefault();
            return false;
          }
        });
        element.bind('mousewheel', function (e) {
          if (e.deltaY > 0 && this.clientHeight + this.scrollTop >= this.scrollHeight) {
            this.scrollTop = this.scrollHeight - this.clientHeight;
            e.stopPropagation();
            e.preventDefault();
            return false;
          }
          else if (e.deltaY < 0 && this.scrollTop <= 0) {
            this.scrollTop = 0;
            e.stopPropagation();
            e.preventDefault();
            return false;
          }

          return true;
        });
      }
  };
});

And then added it to the scrollable element (the dropdown-menu ul):

<div class="dropdown">
  <button type="button" class="btn dropdown-toggle">Rename <span class="caret"></span></button>
  <ul class="dropdown-menu" isolate-scrolling>
    <li ng-repeat="s in savedSettings | objectToArray | orderBy:'name' track by s.name">
      <a ng-click="renameSettings(s.name)">{{s.name}}</a>
    </li>
  </ul>
</div>

Tested on Chrome and Firefox. Chrome's smooth scrolling defeats this hack when a large mousewheel movement is made near (but not at) the top or bottom of the scroll region.

The information schema isn't the place to treat these things (see DDL database commands).

When you add a comment you need to change the table structure (table comments).

From MySQL 5.6 documentation:

INFORMATION_SCHEMA is a database within each MySQL instance, the place that stores information about all the other databases that the MySQL server maintains. The INFORMATION_SCHEMA database contains several read-only tables. They are actually views, not base tables, so there are no files associated with them, and you cannot set triggers on them. Also, there is no database directory with that name.

Although you can select INFORMATION_SCHEMA as the default database with a USE statement, you can only read the contents of tables, not perform INSERT, UPDATE, or DELETE operations on them.

Chapter 21 INFORMATION_SCHEMA Tables

firstly import the class

import java.net.InetAddress;

in class

  InetAddress iAddress = InetAddress.getLocalHost();
  String currentIp = iAddress.getHostAddress();
  System.out.println("Current IP address : " +currentIp); //gives only host address

Try giving some padding bottom to your constraint layout like below

    <ScrollView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_below="@+id/top"
        android:fillViewport="true">

        <android.support.constraint.ConstraintLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:paddingBottom="100dp">
        </android.support.constraint.ConstraintLayout>

    </ScrollView>

For each iteration of the ng-repeat loop, line is a reference to an object in your array. Therefore, to preview the value, use {{line.text}}.

Similarly, to databind to the text, databind to the same: ng-model="line.text". You don't need to use value when using ng-model (actually you shouldn't).

Fiddle.

For a more in-depth look at scopes and ng-repeat, see What are the nuances of scope prototypal / prototypical inheritance in AngularJS?, section ng-repeat.

This appears to be my "preferred" solution:

<form action="www.spufalcons.com/index.aspx?tab=gymnastics&path=gym" method="post">  <div>
<input type="submit" value="Gymnastics"></div>

Sorry for the presentation format - I'm still trying to learn how to use this forum....

I do have a follow-up question. In looking at my MySQL database of URL's it appears that ~30% of the URL's will need to use this post/div wrapper approach. This leaves ~70% that cannot accept the "post" attribute. For example:

<form action="http://www.google.com" method="post">
  <div>
    <input type="submit" value="Google"/>
  </div></form>

does not work. Do you have a recommendation for how to best handle this get/post condition test. Off the top of my head I'm guessing that using PHP to evaluate the existence of the "?" character in the URL may be my best approach, although I'm not sure how to structure the HTML form to accomplish this.

Thank YOU!

I've had this issue on a lot of mobile views I've recently built.

My solution is still a pure CSS Fallback

http://css-tricks.com/perfect-full-page-background-image/ as three great methods, the latter two are fall backs for when CSS3's cover doesn't work.

HTML

<img src="images/bg.jpg" id="bg" alt="">

CSS

#bg {
  position: fixed; 
  top: 0; 
  left: 0; 

  /* Preserve aspect ratio */
  min-width: 100%;
  min-height: 100%;
}

There is an option in Postman if you download it from https://www.getpostman.com instead of the chrome store (most probably it has been introduced in the new versions and the chrome one will be updated later) not sure about the old ones.

In the settings, turn off the SSL certificate verification option

Be sure to remember to reactivate it afterwards, this is a security feature.

If you really want to use the chrome app, you could always add an exception to chrome for the url: Enter the url you would like to open in the chrome browser, you'll get a warning with a link at the bottom of the page to add an exception, which if you do, it will also allow postman to access your url. But the first option of using the postman stand-alone app is much better.

I hope this can help.

You could wrap all your checkboxes in a parent class and check the length of .checked..

if( $('.your-parent-class').find('.checked').length ){
  $(".hide").toggle();
}

To check online you can use

http://codebeautify.org/base64-to-image-converter

You can convert string to image like this way

import android.graphics.Bitmap;
import android.graphics.BitmapFactory;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Base64;
import android.widget.ImageView;

import java.io.ByteArrayOutputStream;

public class MainActivity extends AppCompatActivity {

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

        ImageView image =(ImageView)findViewById(R.id.image);

        //encode image to base64 string
        ByteArrayOutputStream baos = new ByteArrayOutputStream();
        Bitmap bitmap = BitmapFactory.decodeResource(getResources(), R.drawable.logo);
        bitmap.compress(Bitmap.CompressFormat.JPEG, 100, baos);
        byte[] imageBytes = baos.toByteArray();
        String imageString = Base64.encodeToString(imageBytes, Base64.DEFAULT);

        //decode base64 string to image
        imageBytes = Base64.decode(imageString, Base64.DEFAULT);
        Bitmap decodedImage = BitmapFactory.decodeByteArray(imageBytes, 0, imageBytes.length);
        image.setImageBitmap(decodedImage);
    }
}

Here is the MySQL documentation on creating new user accounts.

In short, you create a user by running a CREATE USER statement:

CREATE USER "<username>" IDENTIFIED BY "<password>";

Once the user is created, you give him access to do things by using the GRANT statement.

Install the cors middleware. We were trying to solve it with our own code, but all attempts failed miserably.

This made it work:

cors = require('cors')
app.use(cors());

Original link

Edit this file (corresponding to your stopped container):

vi /var/lib/docker/containers/923...4f6/config.json

Change the "Path" parameter to point at your new command, e.g. /bin/bash. You may also set the "Args" parameter to pass arguments to the command.

Restart the docker service (note this will stop all running containers):

service docker restart

List your containers and make sure the command has changed:

docker ps -a

Start the container and attach to it, you should now be in your shell!

docker start -ai mad_brattain

Worked on Fedora 22 using Docker 1.7.1.

NOTE: If your shell is not interactive (e.g. you did not create the original container with -it option), you can instead change the command to "/bin/sleep 600" or "/bin/tail -f /dev/null" to give you enough time to do "docker exec -it CONTID /bin/bash" as another way of getting a shell.

NOTE2: Newer versions of docker have config.v2.json, where you will need to change either Entrypoint or Cmd (thanks user60561).

Currently, I am using Ubuntu 16.04 LTS. Me too was facing same problem while Fetching the Postgress Database values using Php so i resolved it by using the below commands.

Mine PHP version is 7.0, so i tried the below command.

apt-get install php-pgsql

Remember to restart Apache.

/etc/init.d/apache2 restart

My question is when should a use a double and when should I use a decimal type?

decimal for when you work with values in the range of 10^(+/-28) and where you have expectations about the behaviour based on base 10 representations - basically money.

double for when you need relative accuracy (i.e. losing precision in the trailing digits on large values is not a problem) across wildly different magnitudes - double covers more than 10^(+/-300). Scientific calculations are the best example here.

which type is suitable for money computations?

decimal, decimal, decimal

Accept no substitutes.

The most important factor is that double, being implemented as a binary fraction, cannot accurately represent many decimal fractions (like 0.1) at all and its overall number of digits is smaller since it is 64-bit wide vs. 128-bit for decimal. Finally, financial applications often have to follow specific rounding modes (sometimes mandated by law). decimal supports these; double does not.

What role do they play when exiting an application in C#?

The same as every other application. Basically they get returned to the caller. Irrelvant if ythe start was an iicon double click. Relevant is the call is a batch file that decides whether the app worked on the return code. SO, unless you write a program that needs this, the return dcode IS irrelevant.

But what is the difference?

One comes from environment one from the System.Windows.Forms?.Application. Functionall there should not bbe a lot of difference.

you can get the value of the respective li by using this method after click

HTML:-

<!DOCTYPE html>
<html>
<head>
    <title>show the value of li</title>
    <link rel="stylesheet"  href="pathnameofcss">
</head>
<body>

    <div id="user"></div>


    <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
    <ul id="pageno">
    <li value="1">1</li>
    <li value="2">2</li>
    <li value="3">3</li>
    <li value="4">4</li>
    <li value="5">5</li>
    <li value="6">6</li>
    <li value="7">7</li>
    <li value="8">8</li>
    <li value="9">9</li>
    <li value="10">10</li>

    </ul>

    <script src="pathnameofjs" type="text/javascript"></script>
</body>
</html>

JS:-

$("li").click(function ()
{       
var a = $(this).attr("value");

$("#user").html(a);//here the clicked value is showing in the div name user
console.log(a);//here the clicked value is showing in the console
});

CSS:-

ul{
display: flex;
list-style-type:none;
padding: 20px;
}

li{
padding: 20px;
}

For completeness, though this probably would not work well given your particular setup (external program + Windows), one can also acquire Scipy hassle-free as part of the (large) SageMath download.

Use a final class. for simplicity you may then use a static import to reuse your values in another class

public final class MyValues {
  public static final String VALUE1 = "foo";
  public static final String VALUE2 = "bar";
}

in another class :

import static MyValues.*
//...

if(variable.equals(VALUE1)){
//...
}

$('li[rel=7]').siblings().andSelf();

// or:

$('li[rel=7]').parent().children();

Now that you added that comment explaining that you want to "form an array of rels per column", you should do this:

var rels = [];

$('ul').each(function() {
    var localRels = [];

    $(this).find('li').each(function(){
        localRels.push( $(this).attr('rel') );
    });

    rels.push(localRels);
});

EDMX model won't work with EF7 but I've found a Community/Professional product which seems to be very powerfull : http://www.devart.com/entitydeveloper/editions.html

This is beacuse the version of mysql to be connected is lower than the version of the mysql driver. Many people say that com.mysql.jdbc.Driver is changed to com.mysql.cj.jdbc.Driver , although this does not solve the problem, but it should also attract attention.

In your TS Definition file, e.g. typings.d.ts`, you can add this line:

declare module "*.json" {
const value: any;
export default value;
}

Then add this in your typescript(.ts) file:-

import * as data from './colors.json';
const word = (<any>data).name;

I was able to respond with the following methods:

1-Install-Package log4net

2-Install-Package MicroKnights.Log4NetAdoNetAppender

3-Install-Package System.Data.SqlClient

First,I Create Database and Table with this Code:

CREATE DATABSE Log4netDb
CREATE TABLE [dbo].[Log] (
    [Id] [int] IDENTITY (1, 1) NOT NULL,
    [Date] [datetime] NOT NULL,
    [Thread] [varchar] (255) NOT NULL,
    [Level] [varchar] (50) NOT NULL,
    [Logger] [varchar] (255) NOT NULL,
    [Message] [varchar] (4000) NOT NULL,
    [Exception] [varchar] (2000) NULL
)

Second, I Create log4net.config File in program . This is a simple configuration with no customization on the log message:

<?xml version="1.0" encoding="utf-8" ?>
<log4net debug="true">
  <!-- definition of the RollingLogFileAppender goes here -->
  <appender name="RollingLogFileAppender" type="log4net.Appender.RollingFileAppender">
    <file value="Logs/WebApp.log" />
    <appendToFile value="true" />
    <rollingStyle value="Size" />
    <maxSizeRollBackups value="10" />
    <maximumFileSize value="10MB" />
    <staticLogFileName value="true" />
    <lockingModel type="log4net.Appender.FileAppender+MinimalLock" />
    <layout type="log4net.Layout.PatternLayout">
      <!-- Format is [date/time] [log level] [thread] message-->
      <conversionPattern value="[%date] [%level] [%thread] %m%n" />
    </layout>
  </appender>
  <appender name="AdoNetAppender" type="MicroKnights.Logging.AdoNetAppender, MicroKnights.Log4NetAdoNetAppender">
    <bufferSize value="1" />
    <connectionType value="System.Data.SqlClient.SqlConnection, System.Data" />
    <connectionStringName value="log4net" />
    <connectionStringFile value="appsettings.json" />
    <commandText value="INSERT INTO Log ([Date],[Thread],[Level],[Logger],[Message]) VALUES (@log_date, @thread, @log_level, @logger, @message)" />
    <parameter>
      <parameterName value="@log_date" />
      <dbType value="DateTime" />
      <layout type="log4net.Layout.RawTimeStampLayout" />
    </parameter>
    <parameter>
      <parameterName value="@thread" />
      <dbType value="String" />
      <size value="255" />
      <layout type="log4net.Layout.PatternLayout">
        <conversionPattern value="%thread" />
      </layout>
    </parameter>
    <parameter>
      <parameterName value="@log_level" />
      <dbType value="String" />
      <size value="50" />
      <layout type="log4net.Layout.PatternLayout">
        <conversionPattern value="%level" />
      </layout>
    </parameter>
    <parameter>
      <parameterName value="@logger" />
      <dbType value="String" />
      <size value="255" />
      <layout type="log4net.Layout.PatternLayout">
        <conversionPattern value="%logger" />
      </layout>
    </parameter>
    <parameter>
      <parameterName value="@message" />
      <dbType value="String" />
      <size value="4000" />
      <layout type="log4net.Layout.PatternLayout">
        <conversionPattern value="%message" />
      </layout>
    </parameter>
    <parameter>
      <parameterName value="@exception" />
      <dbType value="String" />
      <size value="2000" />
      <layout type="log4net.Layout.ExceptionLayout" />
    </parameter>
  </appender>
  <root>
    <level value="ALL" />
    <appender-ref ref="RollingLogFileAppender" />
    <appender-ref ref="AdoNetAppender" />
  </root>
</log4net>

Third, Replace code below with 'IHostBuilder' :

public static IWebHostBuilder CreateWebHostBuilder(string[] args) =>
    WebHost.CreateDefaultBuilder(args)
    .ConfigureLogging(logging =>
    {
        // clear default logging providers
        logging.ClearProviders();
        logging.AddConsole();  
        logging.AddDebug();
        logging.AddEventLog();
        // add more providers here
    })
    .UseStartup<Startup>();

Fourth, in appsettings.json insert this code:

{
  "connectionStrings": {
    "log4net": "Server=MICKO-PC;Database=Log4netDb;Trusted_Connection=True;MultipleActiveResultSets=true"
  }
}

At the end, Use these commands to enjoy logging in

public class ValuesController : Controller
{
    private static readonly ILog log = LogManager.GetLogger(typeof(ValuesController));
    
    [HttpPost]
    public async Task<IActionResult> Login(string userName, string password)
    {
        log.Info("Action start");
        
        // More code here ...
        log.Info("Action end");
    }
    
    // More code here...
} 

Good luck.

Use Is Null

select * from tblName where clmnName is null    

I found the nice resource Standard C++ Containers. Probably this is what you all looking for.

VECTOR

Constructors

vector<T> v;              Make an empty vector.                                     O(1)

v.erase(begin, end)        Erase the elements from begin to end.                            O(n)

For other containers, refer to the page.

Here is another simple way to do it

<a class="nav-link"
   href='@Url.Action("Print1", "DeviceCertificates", new { Area = "Diagnostics"})\@Model.ID'>Print</a>

Where is @Model.ID is a parameter

And here there is a second example.

<a class="nav-link"
   href='@Url.Action("Print1", "DeviceCertificates", new { Area = "Diagnostics"})\@Model.ID?param2=ViewBag.P2&param3=ViewBag.P3'>Print</a>

please try with below query

select id,numbers_from,created_date,amount_numbers,SMS_text 
from Test_Table
where 
convert(datetime, convert(varchar(10), created_date, 102))  <= convert(datetime,'2013-04-12')

i realize this post is several years old now, but sometimes certified newbies such as myself need a working example that is totally stripped down to the absolute most simplest form.

every simple socket.io example i could find involved http.createServer(). but what if you want to include a bit of socket.io magic in an existing webpage? here is the absolute easiest and smallest example i could come up with.

this just returns a string passed from the console UPPERCASED.

app.js

var http = require('http');

var app = http.createServer(function(req, res) {
        console.log('createServer');
});
app.listen(3000);

var io = require('socket.io').listen(app);


io.on('connection', function(socket) {
    io.emit('Server 2 Client Message', 'Welcome!' );

    socket.on('Client 2 Server Message', function(message)      {
        console.log(message);
        io.emit('Server 2 Client Message', message.toUpperCase() );     //upcase it
    });

});

index.html:

<!doctype html>
<html>
    <head>
        <script type='text/javascript' src='http://localhost:3000/socket.io/socket.io.js'></script>
        <script type='text/javascript'>
                var socket = io.connect(':3000');
                 // optionally use io('http://localhost:3000');
                 // but make *SURE* it matches the jScript src
                socket.on ('Server 2 Client Message',
                     function(messageFromServer)       {
                        console.log ('server said: ' + messageFromServer);
                     });

        </script>
    </head>
    <body>
        <h5>Worlds smallest Socket.io example to uppercase strings</h5>
        <p>
        <a href='#' onClick="javascript:socket.emit('Client 2 Server Message', 'return UPPERCASED in the console');">return UPPERCASED in the console</a>
                <br />
                socket.emit('Client 2 Server Message', 'try cut/paste this command in your console!');
        </p>
    </body>
</html>

to run:

npm init;  // accept defaults
npm  install  socket.io  http  --save ;
node app.js  &

use something like this port test to ensure your port is open.

now browse to http://localhost/index.html and use your browser console to send messages back to the server.

at best guess, when using http.createServer, it changes the following two lines for you:

<script type='text/javascript' src='/socket.io/socket.io.js'></script>
var socket = io();

i hope this very simple example spares my fellow newbies some struggling. and please notice that i stayed away from using "reserved word" looking user-defined variable names for my socket definitions.

just change state config to disable and choose what you want, background Image for disabled state

I trained a neural network in Keras to perform non linear regression on some data. This is some part of my code for testing on new data using previously saved model configuration and weights.

fname = r"C:\Users\tauseef\Desktop\keras\tutorials\BestWeights.hdf5"
modelConfig = joblib.load('modelConfig.pkl')
recreatedModel = Sequential.from_config(modelConfig)
recreatedModel.load_weights(fname)
unseenTestData = np.genfromtxt(r"C:\Users\tauseef\Desktop\keras\arrayOf100Rows257Columns.txt",delimiter=" ")
X_test = unseenTestData
standard_scalerX = StandardScaler()
standard_scalerX.fit(X_test)
X_test_std = standard_scalerX.transform(X_test)
X_test_std = X_test_std.astype('float32')
unseenData_predictions = recreatedModel.predict(X_test_std)

This is the syntax you need:

CASE WHEN countries LIKE '%'+@selCountry+'%' THEN 'national' ELSE 'regional' END

Although, as per your original problem, I'd solve it differently, splitting the content of @selcountry int a table form and joining to it.

Personally, I'd append the element to the form instead of hacking the serialized data, e.g.

moredata = 'your custom data here';

// do what you like with the input
$input = $('<input type="text" name="moredata"/>').val(morevalue);

// append to the form
$('#myForm').append($input);

// then..
data: $('#myForm').serialize()

That way, you don't have to worry about ? or &

This will keep the \n character, but you can also just wrap the quote in parentheses. Especially useful in RMarkdown.

t <- ("
this is a long
string
")

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) 
    textView.setTextAppearance(R.style.yourStyle)

I believe you need to .f file as a parameter, not as a command-single-string. same with the "--domain "+i, which i would split in two elements of the list. Assuming that:

• you have the path set for FORTRAN executable,
• the ~/ is indeed the correct way for the FORTRAN executable

I would change this line:

subprocess.Popen(["FORTRAN ~/C:/Users/Vishnu/Desktop/Fortran_Program_Rum/phase1.f", "--domain "+i])

to

subprocess.Popen(["FORTRAN", "~/C:/Users/Vishnu/Desktop/Fortran_Program_Rum/phase1.f", "--domain", i])

If that doesn't work, you should do a os.path.exists() for the .f file, and check that you can launch the FORTRAN executable without any path, and set the path or system path variable accordingly

[EDIT 6-Mar-2017]

As the exception, detailed in the original post, is a python exception from subprocess; it is likely that the WinError 2 is because it cannot find FORTRAN

I highly suggest that you specify full path for your executable:

for i in input:
    exe = r'c:\somedir\fortrandir\fortran.exe'
    fortran_script = r'~/C:/Users/Vishnu/Desktop/Fortran_Program_Rum/phase1.f'
    subprocess.Popen([exe, fortran_script, "--domain", i])

if you need to convert the forward-slashes to backward-slashes, as suggested in one of the comments, you can do this:

for i in input:
    exe = os.path.normcase(r'c:\somedir\fortrandir\fortran.exe')
    fortran_script = os.path.normcase(r'~/C:/Users/Vishnu/Desktop/Fortran_Program_Rum/phase1.f')
    i = os.path.normcase(i)
    subprocess.Popen([exe, fortran_script, "--domain", i])

[EDIT 7-Mar-2017]

The following line is incorrect:

exe = os.path.normcase(r'~/C:/Program Files (x86)/Silverfrost/ftn95.exe'

I am not sure why you have ~/ as a prefix for every path, don't do that.

for i in input:
    exe = os.path.normcase(r'C:/Program Files (x86)/Silverfrost/ftn95.exe'
    fortran_script = os.path.normcase(r'C:/Users/Vishnu/Desktop/Fortran_Program_Rum/phase1.f')
    i = os.path.normcase(i)
    subprocess.Popen([exe, fortran_script, "--domain", i])

[2nd EDIT 7-Mar-2017]

I do not know this FORTRAN or ftn95.exe, does it need a shell to function properly?, in which case you need to launch as follows:

subprocess.Popen([exe, fortran_script, "--domain", i], shell = True)

You really need to try to launch the command manually from the working directory which your python script is operating from. Once you have the command which is actually working, then build up the subprocess command.

create table demotable(group_id number, name varchar2(100));
insert into demotable values(1,'David');
insert into demotable values(1,'John');
insert into demotable values(1,'Alan');
insert into demotable values(1,'David');
insert into demotable values(2,'Julie');
insert into demotable values(2,'Charles');
commit;

select group_id, 
       (select listagg(column_value, ',') within group (order by column_value) from table(coll_names)) as names
from (
  select group_id, collect(distinct name) as coll_names 
    from demotable
    group by group_id 
)

GROUP_ID    NAMES
1   Alan,David,John
2   Charles,Julie

you could also do it this way, in my case i use it before and after an h1 (brute force it ehehehe)

.titleImage::before {
content: "--------";
letter-spacing: -3px;
}

.titreImage::after {
content: "--------";
letter-spacing: -3px;
}

If the letter spacing makes it so the line get in the text just use a margin to push it away!

In pyspark,SparkSql syntax:

where column_n like 'xyz%'

might not work.

Use:

where column_n RLIKE '^xyz' 

This works perfectly fine.

With the current version of Recaptcha (reCAPTCHA API version 2.0), you can have multiple recaptchas on one page.

There is no need to clone the recaptcha nor try to workaround the problem. You just have to put multiple div elements for the recaptchas and render the recaptchas inside them explicitly.

This is easy with the google recaptcha api:
https://developers.google.com/recaptcha/docs/display#explicit_render

Here is the example html code:

<form>
    <h1>Form 1</h1>
    <div><input type="text" name="field1" placeholder="field1"></div>
    <div><input type="text" name="field2" placeholder="field2"></div>
    <div id="RecaptchaField1"></div>
    <div><input type="submit"></div>
</form>

<form>
    <h1>Form 2</h1>
    <div><input type="text" name="field3" placeholder="field3"></div>
    <div><input type="text" name="field4" placeholder="field4"></div>
    <div id="RecaptchaField2"></div>
    <div><input type="submit"></div>
</form>

In your javascript code, you have to define a callback function for recaptcha:

<script type="text/javascript">
    var CaptchaCallback = function() {
        grecaptcha.render('RecaptchaField1', {'sitekey' : '6Lc_your_site_key'});
        grecaptcha.render('RecaptchaField2', {'sitekey' : '6Lc_your_site_key'});
    };
</script>

After this, your recaptcha script url should look like this:

<script src="https://www.google.com/recaptcha/api.js?onload=CaptchaCallback&render=explicit" async defer></script>

Or instead of giving IDs to your recaptcha fields, you can give a class name and loop these elements with your class selector and call .render()

Try this it will work --

if($('#EventStartTimeMin').val() === " ") {

    alert("Please enter start time!");

}

In case if String position is not fixed then by below Select statement we can get the expected output.

Table Structure ID VARCHAR2(100 BYTE) CLIENT VARCHAR2(4000 BYTE)

Data- ID CLIENT
1001 {"clientId":"con-bjp","clientName":"ABC","providerId":"SBS"}
1002 {"IdType":"AccountNo","Id":"XXXXXXXX3521","ToPricingId":"XXXXXXXX3521","clientId":"Test-Cust","clientName":"MFX"}

Requirement - Search "ClientId" string in CLIENT column and return the corresponding value. Like From "clientId":"con-bjp" --> con-bjp(Expected output)

select CLIENT,substr(substr(CLIENT,instr(CLIENT,'"clientId":"')+length('"clientId":"')),1,instr(substr(CLIENT,instr(CLIENT,'"clientId":"')+length('"clientId":"')),'"',1 )-1) cut_str from TEST_SC;

CLIENT cut_str ----------------------------------------------------------- ---------- {"clientId":"con-bjp","clientName":"ABC","providerId":"SBS"} con-bjp {"IdType":"AccountNo","Id":"XXXXXXXX3521","ToPricingId":"XXXXXXXX3521","clientId":"Test-Cust","clientName":"MFX"} Test-Cust

What is the correct C# way of representing a data structure...

Remeber, "All models are wrong, but some are useful." -George E. P. Box

There is no a "correct way", only a useful one.

Choose one that is useful to you and/your users. That's it. Develop economically, don't over-engineer. The less code you write, the less code you will need to debug. (read the following editions).

-- Edited

My best answer would be... it depends. Inheriting from a List would expose the clients of this class to methods that may be should not be exposed, primarily because FootballTeam looks like a business entity.

-- Edition 2

I sincerely don't remember to what I was referring on the “don't over-engineer” comment. While I believe the KISS mindset is a good guide, I want to emphasize that inheriting a business class from List would create more problems than it resolves, due abstraction leakage.

On the other hand, I believe there are a limited number of cases where simply to inherit from List is useful. As I wrote in the previous edition, it depends. The answer to each case is heavily influenced by both knowledge, experience and personal preferences.

Thanks to @kai for helping me to think more precisely about the answer.

List<Conversation> conversations = **jdbcTemplate**.**queryForList**(
            **SQL_QUERY**,
            new Object[] {userId, dateFrom, dateTo});  //placeholders values

Suppose the sql query is like

SQL_QUERY = "**select** info,count(*),IF(info is null , 'DATA' , 'NO DATA') **from** table where userId=? , dateFrom=? , dateTo=?";

**HERE userId=? , dateFrom=? , dateTo=?**

the question marks are place holders

**SQL_QUERY**,
            new Object[] {userId, dateFrom, dateTo});

It will go as an object array along with the sql query

The absolute easiest way to stream a file into browser using ASP.NET MVC is this:

public ActionResult DownloadFile() {
    return File(@"c:\path\to\somefile.pdf", "application/pdf", "Your Filename.pdf");
}

This is easier than the method suggested by @azarc3 since you don't even need to read the bytes.

** Edit **

Apparently my 'answer' is the same as the OP's question. But I am not facing the problem he is having. Probably this was an issue with older version of ASP.NET MVC?

Try installing it again with the stand alone installer https://software.intel.com/en-us/android/articles/intel-hardware-accelerated-execution-manager-end-user-license-agreement - assuming you have a CPU that supports Virtualization, have turned off antivirus and any hypervisor.

You can change

Range("B3:B65536").Copy Destination:=Sheets("DB").Range("B" & lastrow)

to

Range("B3:B65536").Copy 
Sheets("DB").Range("B" & lastrow).PasteSpecial xlPasteValues

BTW, if you have xls file (excel 2003), you would get an error if your lastrow would be greater 3.

Try to use this code instead:

Sub Get_Data()
    Dim lastrowDB As Long, lastrow As Long
    Dim arr1, arr2, i As Integer

    With Sheets("DB")
        lastrowDB = .Cells(.Rows.Count, "A").End(xlUp).Row + 1
    End With

    arr1 = Array("B", "C", "D", "E", "F", "AH", "AI", "AJ", "J", "P", "AF")
    arr2 = Array("B", "A", "C", "P", "D", "E", "G", "F", "H", "I", "J")

    For i = LBound(arr1) To UBound(arr1)
        With Sheets("Sheet1")
             lastrow = Application.Max(3, .Cells(.Rows.Count, arr1(i)).End(xlUp).Row)
             .Range(.Cells(3, arr1(i)), .Cells(lastrow, arr1(i))).Copy
             Sheets("DB").Range(arr2(i) & lastrowDB).PasteSpecial xlPasteValues
        End With
    Next
    Application.CutCopyMode = False
End Sub

Note, above code determines last non empty row on DB sheet in column A (variable lastrowDB). If you need to find lastrow for each destination column in DB sheet, use next modification:

For i = LBound(arr1) To UBound(arr1)
   With Sheets("DB")
       lastrowDB = .Cells(.Rows.Count, arr2(i)).End(xlUp).Row + 1
   End With

   ' NEXT CODE

Next

You could also use next approach instead Copy/PasteSpecial. Replace

.Range(.Cells(3, arr1(i)), .Cells(lastrow, arr1(i))).Copy
Sheets("DB").Range(arr2(i) & lastrowDB).PasteSpecial xlPasteValues

with

Sheets("DB").Range(arr2(i) & lastrowDB).Resize(lastrow - 2).Value = _
      .Range(.Cells(3, arr1(i)), .Cells(lastrow, arr1(i))).Value

This is how I got it to work:
