1. Prerequisite: You must know how to use decorators and specially with wraps. This comment explains it a bit clear or this link also explains it pretty well.

2. Whenever we use For eg: @wraps followed by our own wrapper function. As per the details given in this link , it says that

functools.wraps is convenience function for invoking update_wrapper() as a function decorator, when defining a wrapper function.

It is equivalent to partial(update_wrapper, wrapped=wrapped, assigned=assigned, updated=updated).

So @wraps decorator actually gives a call to functools.partial(func[,*args][, **keywords]).

The functools.partial() definition says that

The partial() is used for partial function application which “freezes” some portion of a function’s arguments and/or keywords resulting in a new object with a simplified signature. For example, partial() can be used to create a callable that behaves like the int() function where the base argument defaults to two:

>>> from functools import partial
>>> basetwo = partial(int, base=2)
>>> basetwo.__doc__ = 'Convert base 2 string to an int.'
>>> basetwo('10010')
18

Which brings me to the conclusion that, @wraps gives a call to partial() and it passes your wrapper function as a parameter to it. The partial() in the end returns the simplified version i.e the object of what's inside the wrapper function and not the wrapper function itself.

Your submission will cancel the redirect or vice versa.

I do not see the reason for the redirect in the first place since why do you have an order form that does nothing.

That said, here is how to do it. Firstly NEVER put code on the submit button but do it in the onsubmit, secondly return false to stop the submission

NOTE This code will IGNORE the action and ONLY execute the script due to the return false/preventDefault

function redirect() {
  window.location.replace("login.php");
  return false;
}

using

<form name="form1" id="form1" method="post" onsubmit="return redirect()">  
  <input type="submit" class="button4" name="order" id="order" value="Place Order" >
</form>

Or unobtrusively:

window.onload=function() {
  document.getElementById("form1").onsubmit=function() {
    window.location.replace("login.php");
    return false;
  }
}

using

<form id="form1" method="post">  
  <input type="submit" class="button4" value="Place Order" >
</form>

jQuery:

$("#form1").on("submit",function(e) {
   e.preventDefault(); // cancel submission
   window.location.replace("login.php");
});

-----

Example:

$("#form1").on("submit", function(e) {_x000D_
  e.preventDefault(); // cancel submission_x000D_
  alert("this could redirect to login.php"); _x000D_
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script>_x000D_
_x000D_
_x000D_
<form id="form1" method="post" action="javascript:alert('Action!!!')">_x000D_
  <input type="submit" class="button4" value="Place Order">_x000D_
</form>

Modified Murtaza Hussain answer:

function unserializeForm($str) {
    $strArray = explode("&", $str);
    foreach($strArray as $item) {
        $array = explode("=", $item);
        $returndata[] = $array;
    }
    return $returndata;
}

I would suggest the following:

String[] parsedInput = str.split("\n"); String firstName = parsedInput[0].split(": ")[1]; String lastName = parsedInput[1].split(": ")[1]; myMap.put(firstName,lastName); 

@John, Earlz and Nathan. The way I learned it at uni is: functions return values, methods don't. In some languages the syntax is/was actually different. Example (no specific language):

Method SetY(int y) ...
Function CalculateY(int x) As Integer ...

Most languages now use the same syntax for both versions, using void as a return type to say there actually isn't a return type. I assume it's because the syntax is more consistent and easier to change from method to function, and vice versa.

Probably because you forgot to implement the solution in the accepted answer. That's the code that makes trim() work.

update

This answer only applies to older browsers. Newer browsers apparently support trim() natively.

import java.io.File;
import java.io.IOException;
import java.lang.management.ManagementFactory;

        cmd.append(System.getProperty("java.home") + File.separator + "bin" + File.separator + "java ");
        for (String jvmArg : ManagementFactory.getRuntimeMXBean().getInputArguments()) {
            cmd.append(jvmArg + " ");
        }
        cmd.append("-cp ").append(ManagementFactory.getRuntimeMXBean().getClassPath()).append(" ");
        cmd.append(Main.class.getName()).append(" ");
        for (String arg : args) {
            cmd.append(arg).append(" ");
        }
        Runtime.getRuntime().exec(cmd.toString());
        System.exit(0);
    }
}

This program collects all information available to reconstruct the original commandline. Then, it launches it and since it is the very same command, your application starts a second time. Then we exit the original program, the child program remains running (even under Linux) and does the very same thing.

The python libs are obsolete with this function. I've done one that works correctly:

import os
import shutil

def copydirectorykut(src, dst):
    os.chdir(dst)
    list=os.listdir(src)
    nom= src+'.txt'
    fitx= open(nom, 'w')

    for item in list:
        fitx.write("%s\n" % item)

    fitx.close()

    f = open(nom,'r')
    for line in f.readlines():
        if "." in line:
            shutil.copy(src+'/'+line[:-1],dst+'/'+line[:-1])
        else:
            if not os.path.exists(dst+'/'+line[:-1]):
                os.makedirs(dst+'/'+line[:-1])
                copydirectorykut(src+'/'+line[:-1],dst+'/'+line[:-1])
            copydirectorykut(src+'/'+line[:-1],dst+'/'+line[:-1])
    f.close()
    os.remove(nom)
    os.chdir('..')

I am using Laravel 4.2. Here how I do it:
I have a directory structure like this one:
app
--controllers
----admin
------AdminController.php

After I have created the controller I've put in the composer.json the path to the new admin directory:

"autoload": {
"classmap": [
"app/commands",
"app/controllers",
"app/controllers/admin",
"app/models",
"app/database/migrations",
"app/database/seeds",
"app/tests/TestCase.php"
]
}, 

Next I have run

composer dump-autoload

and then

php artisan dump-autoload

Then in the routes.php I have the controller included like this:

Route::controller('admin', 'AdminController');

And everything works fine.

Why don't you try it like this:

$Weddingdate = new DateTime($row2['weddingdate']);
$formattedweddingdate = date_format($Weddingdate, 'd-m-Y');

Or you can also just do it like :

$Weddingdate = new DateTime($row2['weddingdate']);
echo $Weddingdate->format('d-m-Y');

If you were to refer to Martin Fowlers book Refactoring improving the design of existing code ! Then there are several cases where it would be good practice eg. long complex conditionals to use a function or method call to assert your case:

"Motivation

One of the most common areas of complexity in a program lies in complex conditional logic. As you write code to test conditions and to do various things depending on various conditions, you quickly end up with a pretty long method. Length of a method is in itself a factor that makes it harder to read, but conditions increase the difficulty. The problem usually lies in the fact that the code, both in the condition checks and in the actions, tells you what happens but can easily obscure why it happens.

As with any large block of code, you can make your intention clearer by decomposing it and replacing chunks of code with a method call named after the intention of that block of code. > With conditions you can receive further benefit by doing this for the conditional part and each of the alternatives. This way you highlight the condition and make it clearly what you > are branching on. You also highlight the reason for the branching."

And yes his answer is also valid for Java implementations. It does not assign the conditional function to a variable though in the examples.

It's TRUE that the overflow needs to be removed or set to initial to make position: sticky works on the child element. I used Material Design in my Angular app and found out that some Material components changed the overflow value. The fix for my scenario is

mat-sidenav-container, mat-sidenav-content {
  overflow: initial;
}

I had issues getting event.stopPropagation() working. If you do too, try moving it to the top of your click handler function, that was what I needed to do to stop the event from bubbling. Example function:

  toggleFilter(e) {
    e.stopPropagation(); // If moved to the end of the function, will not work
    let target = e.target;
    let i = 10; // Sanity breaker

    while(true) {
      if (--i === 0) { return; }
      if (target.classList.contains("filter")) {
        target.classList.toggle("active");
        break;
      }
      target = target.parentNode;
    }
  }

This msdn article explains it very well with examples, "A tuple is a data structure that has a specific number and sequence of elements".

Tuples are commonly used in four ways:

1. To represent a single set of data. For example, a tuple can represent a database record, and its components can represent individual fields of the record.

2. To provide easy access to, and manipulation of, a data set.

3. To return multiple values from a method without using out parameters (in C#) or ByRef parameters (in Visual Basic).

4. To pass multiple values to a method through a single parameter. For example, the Thread.Start(Object) method has a single parameter that lets you supply one value to the method that the thread executes at startup time. If you supply a Tuple<T1, T2, T3> object as the method argument, you can supply the thread’s startup routine with three items of data.

Basically Spring is a framework for dependency-injection which is a pattern that allows building very decoupled systems.

The problem

For example, suppose you need to list the users of the system and thus declare an interface called UserLister:

public interface UserLister {
    List<User> getUsers();
}

And maybe an implementation accessing a database to get all the users:

public class UserListerDB implements UserLister {
    public List<User> getUsers() {
        // DB access code here
    }
}

In your view you'll need to access an instance (just an example, remember):

public class SomeView {
    private UserLister userLister;

    public void render() {
        List<User> users = userLister.getUsers();
        view.render(users);
    }
}

Note that the code above hasn't initialized the variable userLister. What should we do? If I explicitly instantiate the object like this:

UserLister userLister = new UserListerDB();

...I'd couple the view with my implementation of the class that access the DB. What if I want to switch from the DB implementation to another that gets the user list from a comma-separated file (remember, it's an example)? In that case, I would go to my code again and change the above line to:

UserLister userLister = new UserListerCommaSeparatedFile();

This has no problem with a small program like this but... What happens in a program that has hundreds of views and a similar number of business classes? The maintenance becomes a nightmare!

Spring (Dependency Injection) approach

What Spring does is to wire the classes up by using an XML file or annotations, this way all the objects are instantiated and initialized by Spring and injected in the right places (Servlets, Web Frameworks, Business classes, DAOs, etc, etc, etc...).

Going back to the example in Spring we just need to have a setter for the userLister field and have either an XML file like this:

<bean id="userLister" class="UserListerDB" />

<bean class="SomeView">
    <property name="userLister" ref="userLister" />
</bean>

or more simply annotate the filed in our view class with @Inject:

@Inject
private UserLister userLister;

This way when the view is created it magically will have a UserLister ready to work.

List<User> users = userLister.getUsers();  // This will actually work
                                           // without adding any line of code

It is great! Isn't it?

• What if you want to use another implementation of your UserLister interface? Just change the XML.
• What if don't have a UserLister implementation ready? Program a temporal mock implementation of UserLister and ease the development of the view.
• What if I don't want to use Spring anymore? Just don't use it! Your application isn't coupled to it. Inversion of Control states: "The application controls the framework, not the framework controls the application".

There are some other options for Dependency Injection around there, what in my opinion has made Spring so famous besides its simplicity, elegance and stability is that the guys of SpringSource have programmed many many POJOs that help to integrate Spring with many other common frameworks without being intrusive in your application. Also, Spring has several good subprojects like Spring MVC, Spring WebFlow, Spring Security and again a loooong list of etceteras.

Hope this helps. Anyway, I encourage you to read Martin Fowler's article about Dependency Injection and Inversion of Control because he does it better than me. After understanding the basics take a look at Spring Documentation, in my opinion, it is used to be the best Spring book ever.

If you're talking about PL/SQL, you should put it in an anonymous block.

DECLARE
    v_text VARCHAR2(10); -- declare
BEGIN
    v_text := 'Hello';  --assign
    dbms_output.Put_line(v_text); --display
END; 

Because most of solutions is bit outdated I could also suggest asciitable which already available in maven (de.vandermeer:asciitable:0.3.2) and may produce very complicated configurations.

Features (by offsite):

• Text table with some flexibility for rules and content, alignment, format, padding, margins, and frames:
• add text, as often as required in many different formats (string, text provider, render provider, ST, clusters),
• removes all excessive white spaces (tabulators, extra blanks, combinations of carriage return and line feed),
• 6 different text alignments: left, right, centered, justified, justified last line left, justified last line right,
• flexible width, set for text and calculated in many different ways for rendering
• padding characters for left and right padding (configurable separately)
• padding characters for top and bottom padding (configurable separately)
• several options for drawing grids
• rules with different styles (as supported by the used grid theme: normal, light, strong, heavy)
• top/bottom/left/right margins outside a frame
• character conversion to generated text suitable for further process, e.g. for LaTeX and HTML

And usage still looks easy:

AsciiTable at = new AsciiTable();

at.addRule();
at.addRow("row 1 col 1", "row 1 col 2");
at.addRule();
at.addRow("row 2 col 1", "row 2 col 2");
at.addRule();

System.out.println(at.render()); // Finally, print the table to standard out.

So let's say after getMasterData servlet will response.sendRedirect to to test.jsp.

In test.jsp

Create a javascript

<script type="text/javascript">
function alertName(){
alert("Form has been submitted");
} 
</script> 

and than at the bottom

<script type="text/javascript"> window.onload = alertName; </script>

Note:im not sure how to type the code in stackoverflow!. Edit: I just learned how to

Edit 2: TO the question:This works perfectly. Another question. How would I get rid of the initial alert when I first start up the JSP? "Form has been submitted" is present the second I execute. It shows up after the load is done to which is perfect.

To do that i would highly recommendation to use session!

So what you want to do is in your servlet:

session.setAttribute("getAlert", "Yes");//Just initialize a random variable.
response.sendRedirect(test.jsp);

than in the test.jsp

<%
session.setMaxInactiveInterval(2);
%>

 <script type="text/javascript">
var Msg ='<%=session.getAttribute("getAlert")%>';
    if (Msg != "null") {
 function alertName(){
 alert("Form has been submitted");
 } 
 }
 </script> 

and than at the bottom

<script type="text/javascript"> window.onload = alertName; </script>

So everytime you submit that form a session will be pass on! If session is not null the function will run!

This problem is usually due to the map div not being rendered before the javascript runs that needs to access it.

You should put your initialization code inside an onload function or at the bottom of your HTML file, just before the tag, so the DOM is completely rendered before it executes (note that the second option is more sensitive to invalid HTML).

Note, as pointed out by matthewsheets this also could be cause by the div with that id not existing at all in your HTML (the pathological case of the div not being rendered)

Adding code sample from wf9a5m75's post to put everything in one place:

<script type="text/javascript">

function initialize() {
    var latlng = new google.maps.LatLng(-34.397, 150.644);
    var myOptions = {
        zoom: 8,
        center: latlng,
        mapTypeId: google.maps.MapTypeId.ROADMAP
    };
    var map = new google.maps.Map(document.getElementById("map_canvas"),
            myOptions);
}
google.maps.event.addDomListener(window, "load", initialize);

</script>

$(".hit").click(function(){
   var values = [];
   var table = $(this).closest("table");
   table.find("tr").each(function() {
      values.push($(this).find("td:first").html());
   });

   alert(values);    
});

You should avoid $(".hit") it's really inefficient. Try using event delegation instead.

Just a word of caution. If you are trying to open an existing JKS keystore in Java 9 onwards, you need to make sure you mention the following properties too with value as "JKS":

javax.net.ssl.keyStoreType
javax.net.ssl.trustStoreType

The reason being that the default keystore type as prescribed in java.security file has been changed to pkcs12 from jks from Java 9 onwards.

You should note that putting generated metadata under version control (let it be git or any other scm), is not a very good idea if there are more than one developer working on the codebase. Two developers may have a totally different project or classpath setup. Just as a heads up in case you intends to share the code at some time...

Converting a byte[] to a string seems simple but any kind of encoding is likely to mess up the output string. This little function just works without any unexpected results:

private string ToString(byte[] bytes)
{
    string response = string.Empty;

    foreach (byte b in bytes)
        response += (Char)b;

    return response;
}

a simpler way search downloads in the start menu and click on downloads in the search results to see where it will take you the drive will be highlighted in the explorer.

Do it in the controller ( controller as syntax below)

controller:

vm.question= {};
vm.question.active = true;

form

<input ng-model="vm.question.active" type="checkbox" id="active" name="active">

CREATE TABLE accounts(
    account_id INT NOT NULL AUTO_INCREMENT,
    customer_id INT( 4 ) NOT NULL ,
    account_type ENUM( 'savings', 'credit' ) NOT NULL,
    balance FLOAT( 9 ) NOT NULL,
    PRIMARY KEY ( account_id )
)

and

CREATE TABLE customers(
    customer_id INT NOT NULL AUTO_INCREMENT,
    name VARCHAR(20) NOT NULL,
    address VARCHAR(20) NOT NULL,
    city VARCHAR(20) NOT NULL,
    state VARCHAR(20) NOT NULL,
)

How do I create a 'relationship' between the two tables? I want each account to be 'assigned' one customer_id (to indicate who owns it).

You have to ask yourself is this a 1 to 1 relationship or a 1 out of many relationship. That is, does every account have a customer and every customer have an account. Or will there be customers without accounts. Your question implies the latter.

If you want to have a strict 1 to 1 relationship, just merge the two tables.

CREATE TABLE customers(
    customer_id INT NOT NULL AUTO_INCREMENT,
    name VARCHAR(20) NOT NULL,
    address VARCHAR(20) NOT NULL,
    city VARCHAR(20) NOT NULL,
    state VARCHAR(20) NOT NULL,
    account_type ENUM( 'savings', 'credit' ) NOT NULL,
    balance FLOAT( 9 ) NOT NULL,
)

In the other case, the correct way to create a relationship between two tables is to create a relationship table.

CREATE TABLE customersaccounts(
    customer_id INT NOT NULL,
    account_id INT NOT NULL,
    PRIMARY KEY (customer_id, account_id)
    FOREIGN KEY customer_id references customers (customer_id) on delete cascade,
    FOREIGN KEY account_id  references accounts  (account_id) on delete cascade
}

Then if you have a customer_id and want the account info, you join on customersaccounts and accounts:

SELECT a.*
    FROM customersaccounts ca
        INNER JOIN accounts a ca.account_id=a.account_id
            AND ca.customer_id=mycustomerid;

Because of indexing this will be blindingly quick.

You could also create a VIEW which gives you the effect of the combined customersaccounts table while keeping them separate

CREATE VIEW customeraccounts AS 
    SELECT a.*, c.* FROM customersaccounts ca
        INNER JOIN accounts a ON ca.account_id=a.account_id
        INNER JOIN customers c ON ca.customer_id=c.customer_id;

An alternative would be to place your regexp in non-capturing parentheses. Then make that expression optional using the ? qualifier, which will look for 0 (i.e. empty string) or 1 instances of the non-captured group.

For example:

/(?: some regexp )?/

In your case the regular expression would look something like this:

/^(?:[\w\.\-]+@([\w\-]+\.)+[a-zA-Z]+)?$/

No | "or" operator necessary!

Here is the Mozilla documentation for JavaScript Regular Expression syntax.

You're looking for Select which can be used to transform\project the input sequence:

IEnumerable<string> strings = integers.Select(i => i.ToString());

You look at the sign of the determinant of

| x2-x1  x3-x1 |
| y2-y1  y3-y1 |

It will be positive for points on one side, and negative on the other (and zero for points on the line itself).

Since no one mentioned this, here's another way:

$date = date_create_from_format("m-d-Y", "10-16-2003")->format("Y-m-d");

But if you are using Plesk, change your settings in :

/usr/local/psa/admin/htdocs/domains/databases/phpMyAdmin/libraries/config.default.php

Change $cfg['ExecTimeLimit'] = 300; to $cfg['ExecTimeLimit'] = 0;

And restart with Plesk UI or use:

/etc/init.d/psa restart and /etc/init.d/httpd restart

It's an old issue but I faced it today in order to fix a build pipeline on our continuous integration server. Adding

<Reference Include="System.Runtime" />

to my .csproj file solved the problem for me.

A bit of context: the interested project is a full .NET Framework 4.6.1 project, without build problem on the development machines. The problem appears only on the build server, which we can't control, may be due to a different SDK version or something similar.

Adding the proposed <Reference solved the build error, at the price of a missing reference warning (yellow triangle on the added entry in the references tree) in Visual Studio.

                      (or 3xx: redirection)

Checks are usually done in this order:

• 404 if resource is public and does not exist or 3xx redirection
• OTHERWISE:
• 401 if not logged-in or session expired
• 403 if user does not have permission to access resource (file, json, ...)
• 404 if resource does not exist or not willing to reveal anything, or 3xx redirection

UNAUTHORIZED: Status code (401) indicating that the request requires authentication, usually this means user needs to be logged-in (session). User/agent unknown by the server. Can repeat with other credentials. NOTE: This is confusing as this should have been named 'unauthenticated' instead of 'unauthorized'. This can also happen after login if session expired. Special case: Can be used instead of 404 to avoid revealing presence or non-presence of resource (credits @gingerCodeNinja)

FORBIDDEN: Status code (403) indicating the server understood the request but refused to fulfill it. User/agent known by the server but has insufficient credentials. Repeating request will not work, unless credentials changed, which is very unlikely in a short time span. Special case: Can be used instead of 404 to avoid revealing presence or non-presence of resource (credits @gingerCodeNinja)

NOT FOUND: Status code (404) indicating that the requested resource is not available. User/agent known but server will not reveal anything about the resource, does as if it does not exist. Repeating will not work. This is a special use of 404 (github does it for example).

As mentioned by @ChrisH there are a few options for redirection 3xx (301, 302, 303, 307 or not redirecting at all and using a 401):

• Difference between HTTP redirect codes
• How long do browsers cache HTTP 301s?
• What is correct HTTP status code when redirecting to a login page?
• What's the difference between a 302 and a 307 redirect?

An array is a pointer. It points to the start of a sequence of "objects".

If we do this: ìnt arr[10];, then arr is a pointer to a memory location, from which ten integers follow. They are uninitialised, but the memory is allocated. It is exactly the same as doing int *arr = new int[10];.

print(encoded3)

Anyway, it is actually exactly the same as the first approach. It may also look that the second way is a syntactic sugar for the third approach.

A programming language is a means to express abstract ideas formally, to be executed by the machine. A programming language is considered good if it contains constructs that one needs. Python is a hybrid language -- i.e. more natural and more versatile than pure OO or pure procedural languages. Sometimes functions are more appropriate than the object methods, sometimes the reverse is true. It depends on mental picture of the solved problem.

Anyway, the feature mentioned in the question is probably a by-product of the language implementation/design. In my opinion, this is a nice example that show the alternative thinking about technically the same thing.

In other words, calling an object method means thinking in terms "let the object gives me the wanted result". Calling a function as the alternative means "let the outer code processes the passed argument and extracts the wanted value".

The first approach emphasizes the ability of the object to do the task on its own, the second approach emphasizes the ability of an separate algoritm to extract the data. Sometimes, the separate code may be that much special that it is not wise to add it as a general method to the class of the object.

you make the use of the HTML Helper and have

    @using(Html.BeginForm())
    {
        Username: <input type="text" name="username" /> <br />
        Password: <input type="text" name="password" /> <br />
        <input type="submit" value="Login">
        <input type="submit" value="Create Account"/>
    }

or use the Url helper

<form method="post" action="@Url.Action("MyAction", "MyController")" >

Html.BeginForm has several (13) overrides where you can specify more information, for example, a normal use when uploading files is using:

@using(Html.BeginForm("myaction", "mycontroller", FormMethod.Post, new {enctype = "multipart/form-data"}))
{
    < ... >
}

If you don't specify any arguments, the Html.BeginForm() will create a POST form that points to your current controller and current action. As an example, let's say you have a controller called Posts and an action called Delete

public ActionResult Delete(int id)
{
   var model = db.GetPostById(id);
   return View(model);
}

[HttpPost]
public ActionResult Delete(int id)
{
    var model = db.GetPostById(id);
    if(model != null) 
        db.DeletePost(id);

    return RedirectToView("Index");
}

and your html page would be something like:

<h2>Are you sure you want to delete?</h2>
<p>The Post named <strong>@Model.Title</strong> will be deleted.</p>

@using(Html.BeginForm())
{
    <input type="submit" class="btn btn-danger" value="Delete Post"/>
    <text>or</text>
    @Url.ActionLink("go to list", "Index")
}

The answer is - it depends.

In basic terms synchronous requests wait for the response to be received from the request before it allows any code processing to continue. At first this may seem like a good thing to do, but it absolutely is not.

As mentioned, while the request is in process the browser will halt execution of all script and also rendering of the UI as the JS engine of the majority of browsers is (effectively) single-threaded. This means that to your users the browser will appear unresponsive and they may even see OS-level warnings that the program is not responding and to ask them if its process should be ended. It's for this reason that synchronous JS has been deprecated and you see warnings about its use in the devtools console.

The alternative of asynchronous requests is by far the better practice and should always be used where possible. This means that you need to know how to use callbacks and/or promises in order to handle the responses to your async requests when they complete, and also how to structure your JS to work with this pattern. There are many resources already available covering this, this, for example, so I won't go into it here.

There are very few occasions where a synchronous request is necessary. In fact the only one I can think of is when making a request within the beforeunload event handler, and even then it's not guaranteed to work.

In summary. you should look to learn and employ the async pattern in all requests. Synchronous requests are now an anti-pattern which cause more issues than they generally solve.

String input = "some input string";
int hashCode = input.hashCode();
System.out.println("input hash code = " + hashCode);

Try this query:

SELECT *
FROM table 
WHERE MONTH(FROM_UNIXTIME(columnName))= MONTH(CURDATE())

The problem is GROUP BY - if you group results by Locus, you only get one result per locus.

Try:

SELECT * FROM Genes WHERE Locus = '3' AND Chromosome = '10';

If you prefer using HAVING syntax, then GROUP BY id or something that is not repeating in the result set.

Using detach is magnitudes faster than any of the other answers here:

$('#mytable').find('tbody').detach();

Don't forget to put the tbody element back into the table since detach removed it:

$('#mytable').append($('<tbody>'));  

Also note that when talking efficiency $(target).find(child) syntax is faster than $(target > child). Why? Sizzle!

Elapsed Time to Empty 3,161 Table Rows

Using the Detach() method (as shown in my example above):

• Firefox: 0.027s
• Chrome: 0.027s
• Edge: 1.73s
• IE11: 4.02s

Using the empty() method:

• Firefox: 0.055s
• Chrome: 0.052s
• Edge: 137.99s (might as well be frozen)
• IE11: Freezes and never returns

You can't resize background images with CSS2.

What you can do is have a container that resizes:

<div style='position:absolute;z-index:0;left:0;top:0;width:100%;height:100%'>
  <img src='whatever.jpg' style='width:100%;height:100%' alt='[]' />
</div>

This way, the div will sit behind the page and take up the whole space, while resizing as needed. The img inside will automatically resize to fit the div.

Unfortunately, the iOS Simulator app does not support saving videos. The easiest thing to do is use Quicktime Player to make a screen recording. Of course, you'll see the mouse interacting with it which is not what you want, but I don't have a better option for you at this time.

From your stack trace, EXC_BAD_INSTRUCTION (code=EXC_I386_INVOP, subcode=0x0) occurred because dispatch_group_t was released while it was still locking (waiting for dispatch_group_leave).

According to what you found, this was what happened :

• dispatch_group_t group was created. group's retain count = 1.
• -[self webservice:onCompletion:] captured the group. group's retain count = 2.
• dispatch_async(...., ^{ dispatch_group_wait(group, ...) ... }); captured the group again. group's retain count = 3.
• Exit the current scope. group was released. group's retain count = 2.
• dispatch_group_leave was never called.
• dispatch_group_wait was timeout. The dispatch_async block was completed. group was released. group's retain count = 1.
• You called this method again. When -[self webservice:onCompletion:] was called again, the old onCompletion block was replaced with the new one. So, the old group was released. group's retain count = 0. group was deallocated. That resulted to EXC_BAD_INSTRUCTION.

To fix this, I suggest you should find out why -[self webservice:onCompletion:] didn't call onCompletion block, and fix it. Then make sure the next call to the method will happen after the previous call did finish.

In case you allow the method to be called many times whether the previous calls did finish or not, you might find someone to hold group for you :

• You can change the timeout from 2 seconds to DISPATCH_TIME_FOREVER or a reasonable amount of time that all -[self webservice:onCompletion] should call their onCompletion blocks by the time. So that the block in dispatch_async(...) will hold it for you.
  OR
• You can add group into a collection, such as NSMutableArray.

I think it is the best approach to create a dedicate class for this action. When you want to make calls to webservice, you then create an object of the class, call the method on it with the completion block passing to it that will release the object. In the class, there is an ivar of dispatch_group_t or dispatch_semaphore_t.

Here's something important that's missing from the other answers: the command-line parameters are exposed to your Ruby shell script through the ARGV (global) array.

So, if you had a script called my_shell_script:

#!/usr/bin/env ruby
puts "I was passed: "
ARGV.each do |value|
  puts value
end

...make it executable (as others have mentioned):

chmod u+x my_shell_script

And call it like so:

> ./my_shell_script one two three four five

You'd get this:

I was passed: 
one
two
three
four
five

The arguments work nicely with filename expansion:

./my_shell_script *

I was passed: 
a_file_in_the_current_directory
another_file    
my_shell_script
the_last_file

Most of this only works on UNIX (Linux, Mac OS X), but you can do similar (though less convenient) things in Windows.

Set s=map.entrySet();
Iterator iter = s.iterator();

while (iter.hasNext()) {
    Map.Entry entry =(Map.Entry)iter.next();

    if("value you need to remove".equals(entry.getKey())) {
         map.remove();
    }
}

Try this code:

String strProc =
         "DECLARE \n" +
         "   sys_date DATE;"+
         "" +
         "BEGIN\n" +
         "" +
         "   SELECT SYSDATE INTO sys_date FROM dual;\n" +
         "" +
         "END;\n";

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

    PreparedStatement psProcToexecute = connection.prepareStatement(strProc);
    psProcToexecute.execute();
}catch (Exception e) {
    System.out.println(e.toString());  
}

I don't know why the first voted answer doesn't work for me.

As this answer said:

There is no 100% solution to delete browser cookies.

The problem is that cookies are uniquely identified by not just by their key "name" but also their "domain" and "path".

Without knowing the "domain" and "path" of a cookie, you cannot reliably delete it. This information is not available through JavaScript's document.cookie. It's not available through the HTTP Cookie header either!

So my idea is to add a Cookie version control with the full set of setting, getting, removing of cookies:

var cookie_version_control = '---2018/5/11';

function setCookie(name,value,days) {
    var expires = "";
    if (days) {
        var date = new Date();
        date.setTime(date.getTime() + (days*24*60*60*1000));
        expires = "; expires=" + date.toUTCString();
    }
    document.cookie = name+cookie_version_control + "=" + (value || "")  + expires + "; path=/";
}

function getCookie(name) {
    var nameEQ = name+cookie_version_control + "=";
    var ca = document.cookie.split(';');
    for(var i=0;i < ca.length;i++) {
        var c = ca[i];
        while (c.charAt(0)==' ') c = c.substring(1,c.length);
        if (c.indexOf(nameEQ) == 0) return c.substring(nameEQ.length,c.length);
    }
    return null;
}

function removeCookie(name) {   
    document.cookie = name+cookie_version_control+'=; Max-Age=-99999999;';  
}

If DAO use

RS.Move 0, RS.LastModified
lngID = RS!AutoNumberFieldName

If ADO use

cn.Execute "INSERT INTO TheTable.....", , adCmdText + adExecuteNoRecords
Set rs = cn.Execute("SELECT @@Identity", , adCmdText)
Debug.Print rs.Fields(0).Value

cn being a valid ADO connection, @@Identity will return the last Identity (Autonumber) inserted on this connection.

Note that @@Identity might be troublesome because the last generated value may not be the one you are interested in. For the Access database engine, consider a VIEW that joins two tables, both of which have the IDENTITY property, and you INSERT INTO the VIEW. For SQL Server, consider if there are triggers that in turn insert records into another table that also has the IDENTITY property.

BTW DMax would not work as if someone else inserts a record just after you've inserted one but before your Dmax function finishes excecuting, then you would get their record.

Simple function to accomplish this:

def insert_str(string, str_to_insert, index):
    return string[:index] + str_to_insert + string[index:]

Use :checkbox selector:

$(':checkbox').change(function() {

What I really don't understand with this kind of problem is that the html page I ran as a local file displayed perfectly in Chromium browser, but as soon as I uploaded it to my website, it produced this error.

Even stranger, it displayed perfectly in the Vivaldi browser whether displayed from the local or remote file.

Is this something to do with the way Chromium reads the character set? But why only with a remote file?

I fixed the problem by retyping the text in a simple text editor and making sure the single quote mark was the one I used.

In this simple example you can just put synchronized as a modifier after public in both method signatures.

More complex scenarios require other stuff.

 <activity android:name=".MainActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

            </intent-filter>
        </activity>

since the data ex1221new was not given, so I have created a dummy data and added it to a data frame. Also, the question which was asked has few changes in codes like then ggplot package has deprecated the use of

"scale_area()" and nows uses scale_size_area()
"opts()" has changed to theme()

In my answer,I have stored the plot in mygraph variable and then I have used

mygraph$labels$x="Discharge of materials" #changes x axis title
       mygraph$labels$y="Area Affected" # changes y axis title

And the work is done. Below is the complete answer.

install.packages("Sleuth2")
library(Sleuth2)
library(ggplot2)

ex1221new<-data.frame(Discharge<-c(100:109),Area<-c(120:129),NO3<-seq(2,5,length.out = 10))
discharge<-ex1221new$Discharge
area<-ex1221new$Area
nitrogen<-ex1221new$NO3
p <- ggplot(ex1221new, aes(discharge, area), main="Point")
mygraph<-p + geom_point(aes(size= nitrogen)) + 
  scale_size_area() + ggtitle("Weighted Scatterplot of Watershed Area vs. Discharge and Nitrogen Levels (PPM)")+
theme(
 plot.title =  element_text(color="Blue", size=30, hjust = 0.5), 

 # change the styling of both the axis simultaneously from this-
 axis.title = element_text(color = "Green", size = 20, family="Courier",)
 

   # you can change the  axis title from the code below
   mygraph$labels$x="Discharge of materials" #changes x axis title
   mygraph$labels$y="Area Affected" # changes y axis title
   mygraph



   

Also, you can change the labels title from the same formula used above -

mygraph$labels$size= "N2" #size contains the nitrogen level 

If you're using ASP.NET MVC, I found Response.AddHeader("X-UA-Compatible", "IE=edge,chrome=1") in a code block in _Layout to work quite well:

End Code

You absolutely need a button tag element? because you can use instead an input type="button" element.

Then just link this CSS:

  input[type="button"]{
  width:150px;
  height:150px;
  /*just this*/ background-image: url(https://images.freeimages.com/images/large-previews/48d/marguerite-1372118.jpg);
  background-position: center;
  background-repeat: no-repeat;
  background-size: 150px 150px;
}

<input type="button"/>

For those who are still searching for a solution without a separate javascript code. There is little easy solution without writing a javascript or jquery function:

<input type="range" value="24" min="1" max="100" oninput="this.nextElementSibling.value = this.value">
<output>24</output>

JsFiddle Demo

If you want to show the value in text box, simply change output to input.

Update:

It is still Javascript written within your html, you can replace the bindings with below JS code:

 document.registrationForm.ageInputId.oninput = function(){
    document.registrationForm.ageOutputId.value = document.registrationForm.ageInputId.value;
 }

Either use element's Id or name, both are supported in morden browsers.

It's also a common convention to use with the first argument of the test method from Kernel#test

irb(main):001:0> test ?d, "/dev" # directory exists?
=> true
irb(main):002:0> test ?-, "/etc/hosts", "/etc/hosts" # are the files identical
=> true

as seen in this question here

Nitin is correct - the issue is actually in the MDB2 code.

According to Replacement for PEAR: MDB2 on PHP 5.3 you can update to the SVN version of MDB2 for a version which is PHP5.3 compatible.

As that answer was given in March 2010, and http://pear.php.net/package/MDB2/ shows a release some months later, I expect the current version of MDB2 will solve the issue also.

Session.destroy(callback)

Destroys the session and will unset the req.session property. Once complete, the callback will be invoked.

↓ Secure way ↓ ?

req.session.destroy((err) => {
  res.redirect('/') // will always fire after session is destroyed
})

↓ Unsecure way ↓ ?

req.logout();
res.redirect('/') // can be called before logout is done

The way you have it is fine but you could create a set of extension methods to make "a more elegant way to check for the 'NOT' instance."

public static bool Is<T>(this object myObject)
{
    return (myObject is T);
}

public static bool IsNot<T>(this object myObject)
{
    return !(myObject is T);
}

Then you could write:

if (child.IsNot<IContainer>())
{
    // child is not an IContainer
}

Here are a few tips and tricks which you can use in your app to support or bypass the dark mode.

First tip: To override the ViewController style

you can override the interface style of UIViewController by

1: overrideUserInterfaceStyle = .dark //For dark mode

2: overrideUserInterfaceStyle = .light //For light mode

class ViewController: UIViewController {
    override func viewDidLoad() {
        super.viewDidLoad()
        overrideUserInterfaceStyle = .light    
    }
}

Second tip: Adding a key in info.plist

Simply you can add a new key

UIUserInterfaceStyle

in your app info.plist and set its value to Light or Dark. this will override the app default style to the value you provide. You don't have to add overrideUserInterfaceStyle = .light this line in every viewController, just one line in info.plist that’s it.

As of August 2020, Google Play's In-App Review API is available and its straightforward implementation is correct as per this answer.

But if you wish add some display logic on top of it, use the Five-Star-Me library.

Set launch times and install days in the onCreate method of the MainActivity to configure the library.

  FiveStarMe.with(this)
      .setInstallDays(0) // default 10, 0 means install day.
      .setLaunchTimes(3) // default 10
      .setDebug(false) // default false
      .monitor();

Then place the below method call on any activity / fragment's onCreate / onViewCreated method to show the prompt whenever the conditions are met.

FiveStarMe.showRateDialogIfMeetsConditions(this); //Where *this* is the current activity.

Installation instructions:

You can download from jitpack.

Step 1: Add this to project (root) build.gradle.

allprojects {
  repositories {
    ...
    maven { url 'https://jitpack.io' }
  }
}

Step 2: Add the following dependency to your module (app) level build.gradle.

dependencies {
  implementation 'com.github.numerative:Five-Star-Me:2.0.0'
}

Old question, but this is what I typically do to make things a bit more readable:

Func<int, string, Tuple<int, string>> tc = Tuple.Create;

var tupleList = new List<Tuple<int, string>>
{
    tc( 1, "cow" ),
    tc( 5, "chickens" ),
    tc( 1, "airplane" )
};

Differences: with respect to heirarchy: HashSet implements Set. HashMap implements Map and stores a mapping of keys and values.

A use of HashSet and HashMap with respect to database would help you understand the significance of each.
HashSet: is generally used for storing unique collection objects. E.g: It might be used as implementation class for storing many-to-one relation ship between
class Item and Class Bid where (Item has many Bids) HashMap: is used to map a key to value.the value may be null or any Object /list of Object (which is object in itself).

For MinGW this worked for me:

• Right click project, select Properties
• Go to C/C++ General - Paths and Symbols - Includes - GNU C++ - Include directories
• Select Add...
• Select Variables...
• Select MINGW_HOME and click OK
• Click Apply and OK

You should now see several MinGW paths in Includes in your project explorer.
The errors may not disappear instantly, you may need to refresh/build your project.

If you are using Cygwin, there could be an equivalent variable present.

If you use static the value of the variable will be the same throughout all of your instances, if changed in one instance the others will change too.

In your example there is no big difference between str -> str and Function.identity() since internally it is simply t->t.

But sometimes we can't use Function.identity because we can't use a Function. Take a look here:

List<Integer> list = new ArrayList<>();
list.add(1);
list.add(2);

this will compile fine

int[] arrayOK = list.stream().mapToInt(i -> i).toArray();

but if you try to compile

int[] arrayProblem = list.stream().mapToInt(Function.identity()).toArray();

you will get compilation error since mapToInt expects ToIntFunction, which is not related to Function. Also ToIntFunction doesn't have identity() method.

Yes, it is because you are using auto layout. Setting the view frame and resizing mask will not work.

You should read Working with Auto Layout Programmatically and Visual Format Language.

You will need to get the current constraints, add the text field, adjust the contraints for the text field, then add the correct constraints on the text field.

A soft real time is easiest to understand, in which even if the result is obtained after the deadline, the results are still considered as valid.

Example: Web browser- We request for certain URL, it takes some time in loading the page. If the system takes more than expected time to provide us with the page, the page obtained is not considered as invalid, we just say that the system's performance wasn't up to the mark (system gave low performance!).

In hard real time system, if the result is obtained after the deadline, the system is considered to have failed completely.

Example: In case of a robot doing some job like line tracing, etc. If a hindrance comes on its path, and the robot doesn't process this information within some programmed deadline (almost instant!), the robot is said to have failed in its task (the robot system may also get completely destroyed!).

In firm real time system, if the result of process execution comes after the deadline, we discard that result, but the system is not termed to have been failed.

Example: Satellite communication for enemy position monitoring or some other task. If the ground computer station to which the satellites send the frames periodically is overloaded, and the current frame (packet) is not processed in time and the next frame comes up, the current packet (the one who missed the deadline) doesn't matter whether the processing was done (or half done or almost done) is dropped/discarded. But the ground computer is not termed to have completely failed.

The latter strings shouldn't start with a slash. If they start with a slash, then they're considered an "absolute path" and everything before them is discarded.

Quoting the Python docs for os.path.join:

If a component is an absolute path, all previous components are thrown away and joining continues from the absolute path component.

Note on Windows, the behaviour in relation to drive letters, which seems to have changed compared to earlier Python versions:

On Windows, the drive letter is not reset when an absolute path component (e.g., r'\foo') is encountered. If a component contains a drive letter, all previous components are thrown away and the drive letter is reset. Note that since there is a current directory for each drive, os.path.join("c:", "foo") represents a path relative to the current directory on drive C: (c:foo), not c:\foo.

If you need to print the number you can use printf

System.out.printf("%02d", num);

You can use

String.format("%02d", num);

or

(num < 10 ? "0" : "") + num;

or

(""+(100+num)).substring(1);

I follow all recommendations and all requirements. I install my self signed root CA on my iPhone. I make it trusted. I put certificate signed with this root CA on my local development server and I still get certificated error on safari iOS. Working on all other platforms.

Either

1. In your cmd console type the following:

   set PATH=%PATH%;C:\Program Files (x86)\Git\bin
   

OR

2. Permanently set the path in your system's environment variables:

   C:\Program Files (x86)\Git\bin;

There is no way to query a database other than the current one. Because PostgreSQL loads database-specific system catalogs, it is uncertain how a cross-database query should even behave.

contrib/dblink allows cross-database queries using function calls. Of course, a client can also make simultaneous connections to different databases and merge the results on the client side.

PostgreSQL FAQ

You have three different problems. First of all, values in HTML tags should be quoted! Not doing this can confuse the browser, and may cause some troubles (although it is likely not the case here). Second, you should actually assign a function to the onclick variable, as someone else meantioned. Not only is this the proper way to do it going forward, but it makes things much simpler if you are trying to use local variables in the onclick function. Finally, you can try either addEventListener or jQuery, jQuery has the advantage of a nicer interface.

Oh, and make sure your HTML validates! That could be an issue.

Something I stumbled upon today for a DLL I knew was working fine with my VS2013 project, but not with VS2015:

There are probably ways of doing that with builtin functions in all shells but it would be less portable. I've not checked the POSIX sh specs to see whether it has such capabilities.

It is generally considered bad practise to have a one to one relationship. This is because you could just have the data represented in one table and achieve the same result.

However, there are instances where you may not be able to make these changes to the table you are referencing. In this instance there is no problem using the Foreign key as the primary key. It might help to have a composite key consisting of an auto incrementing unique primary key and the foreign key.

I am currently working on a system where users can log in and generate a registration code to use with an app. For reasons I won't go into I am unable to simply add the columns required to the users table. So I am going down a one to one route with the codes table.

The /etc/apache2/httpd.conf is empty in Ubuntu, because the Apache configuration resides in /etc/apache2/apache2.conf!

“httpd.conf is for user options.” No it isn't, it's there for historic reasons.

Using Apache server, all user options should go into a new *.conf-file inside /etc/apache2/conf.d/. This method should be "update-safe", as httpd.conf or apache2.conf may get overwritten on the next server update.

Inside /etc/apache2/apache2.conf, you will find the following line, which includes those files:

# Include generic snippets of statements
Include conf.d/

As of Apache 2.4+ the user configuration directory is /etc/apache2/conf-available/. Use a2enconf FILENAME_WITHOUT_SUFFIX to enable the new configuration file or manually create a symlink in /etc/apache2/conf-enabled/. Be aware that as of Apache 2.4 the configuration files must have the suffix .conf (e.g. conf-available/my-settings.conf);

Short Extension Method:

public static TResult IfNotNull<TInput, TResult>(this TInput o, Func<TInput, TResult> evaluator)
  where TResult : class where TInput : class
{
  if (o == null) return null;
  return evaluator(o);
}

Using

PropertyC value = ObjectA.IfNotNull(x => x.PropertyA).IfNotNull(x => x.PropertyB).IfNotNull(x => x.PropertyC);

This simple extension method and much more you can find on http://devtalk.net/csharp/chained-null-checks-and-the-maybe-monad/

EDIT:

After using it for moment I think the proper name for this method should be IfNotNull() instead of original With().

Though all above answers are correct, below one is handy to use if you need count of last many commits

below one is to get count of last 5 commits

git diff $(git log -5 --pretty=format:"%h" | tail -1) --shortstat

to get count of last 10 commits

git diff $(git log -10 --pretty=format:"%h" | tail -1) --shortstat

generic - change N with count of last many commits you need

git diff $(git log -N --pretty=format:"%h" | tail -1) --shortstat

to get count of all commits since start

git diff $(git log --pretty=format:"%h" | tail -1) --shortstat

I was having the same problem, although I solved out by creating the table using a script query instead of doing it graphically. See the snipped below:

USE [Database_Name]
GO

CREATE TABLE [dbo].[Table_Name](
[tableID] [int] IDENTITY(1,1) NOT NULL,
[column_2] [datatype] NOT NULL,
[column_3] [datatype] NOT NULL,

CONSTRAINT [PK_Table_Name] PRIMARY KEY CLUSTERED 
(
[tableID] ASC
)
)

easy:

launching activity (onclick handler)

 Intent myIntent = new Intent(CurrentActivity.this, NextActivity.class);
 myIntent.putExtra("key", value); //Optional parameters
 CurrentActivity.this.startActivity(myIntent);

on the new activity:

@Override
protected void onCreate(Bundle savedInstanceState) {
Intent intent = getIntent();
String value = intent.getStringExtra("key"); //if it's a string you stored.

and add your new activity in the AndroidManifest.xml:

<activity android:label="@string/app_name" android:name="NextActivity"/>

You need the git config alias command. Execute the following in a Git repository:

git config alias.ci commit

For global alias:

git config --global alias.ci commit

Okay, seems like a bit of a hack. I have got it to work using a substring, so that only the part of the string with the date (not the time) gets passed into the DATE function...

DATE(substr(SETTLEMENTDATE.VALUE,7,4)||'-'|| substr(SETTLEMENTDATE.VALUE,4,2)||'-'|| substr(SETTLEMENTDATE.VALUE,1,2))

I will still accept any answers that are better than this one!

You can use AppendDataBoundItems=true to easily add:

<asp:DropDownList ID="drpList" AppendDataBoundItems="true" runat="server">
    <asp:ListItem Text="" Value="" />
</asp:DropDownList>

Oh, just with this:

$ docker-compose up client server database

If you are using the following stack: Server Version: Apache Tomcat/9.0.21 Servlet Version: 4.0 JSP Version: 2.3

Then try adding <absolute-ordering /> to your web.xml file. So your file looks like this:

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" id="WebApp_ID" version="3.1">

  <absolute-ordering />

  <welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
    <welcome-file>index.html</welcome-file>
  </welcome-file-list>

  ......

If you don't know the row number, but do know some values then you can use subset

x <- structure(list(A = c(5,    3.5, 3.25, 4.25,  1.5 ), 
                    B = c(4.25, 4,   4,    4.5,   4.5 ),
                    C = c(4.5,  2.5, 4,    2.25,  3   )
               ),
               .Names    = c("A", "B", "C"),
               class     = "data.frame",
               row.names = c(NA, -5L)
     )

subset(x, A ==5 & B==4.25 & C==4.5)

Already answered above, but here's another approach you could take. I can't find the original post I adapted this from, but here's the code for the sake of your question. As noted above, the flatMap() function is what you'd be looking to utilize with Java 8. You can throw it in a utility class and just call "RandomUtils.combine(list1, list2, ...);" and you'd get a single List with all values. Just be careful with the wildcard - you could change this if you want a less generic method. You can also modify it for Sets - you just have to take care when using flatMap() on Sets to avoid data loss from equals/hashCode methods due to the nature of the Set interface.

Edit - If you use a generic method like this for the Set interface, and you happen to use Lombok, make sure you understand how Lombok handles equals/hashCode generation.

  /**
    * Combines multiple lists into a single list containing all elements of
    * every list.
    * 
    * @param <T> - The type of the lists.
    * @param lists - The group of List implementations to combine
    * @return a single List<?> containing all elements of the passed in lists.
    */
   public static <T> List<?> combine(final List<?>... lists) {
      return Stream.of(lists).flatMap(List::stream).collect(Collectors.toList());
   }

<div id="OK1"  runat="server" style ="display:none" >
    <asp:DropDownList ID="DropDownList2" runat="server"></asp:DropDownList>

vb.net code

  Protected Sub DropDownList1_SelectedIndexChanged(sender As Object, e As EventArgs) Handles DropDownList1.SelectedIndexChanged
    If DropDownList1.SelectedIndex = 0 Then
        OK1.Style.Add("display", "none")
    Else
        OK1.Style.Add("display", "block")
    End If
End Sub

awk 's+=$2{print s/NR}' table | tail -1

I am using tail -1 to print the last line which should have the average number...

I developed a generic statement to apply the filter:

string rowFilter = string.Format("[{0}] = '{1}'", columnName, filterValue);
(myDataGridView.DataSource as DataTable).DefaultView.RowFilter = rowFilter;

The square brackets allow for spaces in the column name.

Additionally, if you want to include multiple values in your filter, you can add the following line for each additional value:

rowFilter += string.Format(" OR [{0}] = '{1}'", columnName, additionalFilterValue);

just use inner join because group by won't work with multiple columns saying not contained in either an aggregate function.

SELECT a.*
FROM yourtable a
INNER JOIN 
  (SELECT yourcolumn,
    MIN(id) as id
  FROM yourtable 
  GROUP BY yourcolumn
) AS b
  ON a.yourcolumn= b.yourcolumn
  AND a.id = b.id;

There are already answers here, but here's my pure JS implementation. I'm not sure if it's optimal, but it sure is transparent, readable, and simple.

// Does array a contain elements of array b?
const contains = (a, b) => new Set([...a, ...b]).size === a.length
const isEqualSet = (a, b) => contains(a, b) && contains(b, a)

The rationale in contains() is that if a does contain all the elements of b, then putting them into the same set would not change the size.

For example, if const a = [1,2,3,4] and const b = [1,2], then new Set([...a, ...b]) === {1,2,3,4}. As you can see, the resulting set has the same elements as a.

From there, to make it more concise, we can boil it down to the following:

const isEqualSet = (a, b) => {
  const unionSize = new Set([...a, ...b])
  return unionSize === a.length && unionSize === b.length
}

The changelog is sloppily worded. from __future__ import absolute_import does not care about whether something is part of the standard library, and import string will not always give you the standard-library module with absolute imports on.

from __future__ import absolute_import means that if you import string, Python will always look for a top-level string module, rather than current_package.string. However, it does not affect the logic Python uses to decide what file is the string module. When you do

python pkg/script.py

pkg/script.py doesn't look like part of a package to Python. Following the normal procedures, the pkg directory is added to the path, and all .py files in the pkg directory look like top-level modules. import string finds pkg/string.py not because it's doing a relative import, but because pkg/string.py appears to be the top-level module string. The fact that this isn't the standard-library string module doesn't come up.

To run the file as part of the pkg package, you could do

python -m pkg.script

In this case, the pkg directory will not be added to the path. However, the current directory will be added to the path.

You can also add some boilerplate to pkg/script.py to make Python treat it as part of the pkg package even when run as a file:

if __name__ == '__main__' and __package__ is None:
    __package__ = 'pkg'

However, this won't affect sys.path. You'll need some additional handling to remove the pkg directory from the path, and if pkg's parent directory isn't on the path, you'll need to stick that on the path too.

BLOB :

BLOB (Binary Large Object) is a large object data type in the database system. BLOB could store a large chunk of data, document types and even media files like audio or video files. BLOB fields allocate space only whenever the content in the field is utilized. BLOB allocates spaces in Giga Bytes.

USAGE OF BLOB :

You can write a binary large object (BLOB) to a database as either binary or character data, depending on the type of field at your data source. To write a BLOB value to your database, issue the appropriate INSERT or UPDATE statement and pass the BLOB value as an input parameter. If your BLOB is stored as text, such as a SQL Server text field, you can pass the BLOB as a string parameter. If the BLOB is stored in binary format, such as a SQL Server image field, you can pass an array of type byte as a binary parameter.

A useful link : Storing documents as BLOB in Database - Any disadvantages ?

There are two ways to do what you are trying

One is a Multi-column Correlated Update

UPDATE PRODUCTION a
SET (name, count) = (
  SELECT name, count
  FROM STAGING b
  WHERE a.ID = b.ID);

DEMO

You can use merge

MERGE INTO PRODUCTION a
USING ( select id, name, count 
          from STAGING ) b
ON ( a.id = b.id )
WHEN MATCHED THEN 
UPDATE SET  a.name = b.name,
            a.count = b.count

DBCC OPENTRAN helps to identify active transactions that may be preventing log truncation. DBCC OPENTRAN displays information about the oldest active transaction and the oldest distributed and nondistributed replicated transactions, if any, within the transaction log of the specified database. Results are displayed only if there is an active transaction that exists in the log or if the database contains replication information.

An informational message is displayed if there are no active transactions in the log.

DBCC OPENTRAN

I had a very similar issue and I'm not quite sure what you're having a problem with, as your suggested code worked great for me. It immediately (a requirement of yours) triggers the following change code.

$('#selectField').change(function(){
    if($('#selectField').val() == 'N'){
        $('#secondaryInput').hide();
    } else {
        $('#secondaryInput').show();
}
});

Then I take the value from the database (this is used on a form for both new input and editing existing records), set it as the selected value, and add the piece I was missing to trigger the above code, ".change()".

$('#selectField').val(valueFromDatabase).change();

So that if the existing value from the database is 'N', it immediately hides the secondary input field in my form.

I hope it will help someone ! (works on Angular 6)

I had to add lots of select/options dynamically and following worked for me:

<div *ngFor="let option of model.q_options; let ind=index;">

        <select 
          [(ngModel)]="model.q_options[ind].type" 
          [ngModelOptions]="{standalone: true}"

            [ngValue]="object.type" 
            [selected]="object.type === model.q_options[ind].type"

          </option>

        <div [ngSwitch]="model.q_options[ind].type">
          ( here <div *ngSwitchCase="'text' or 'imagelocal' or etc."> is used to add specific input forms )
        </div>
</div>

and in *.ts

// initial state of the model
// q_options in html = NewOption and its second argument is option type
model = new NewQuestion(1, null, 2, 
  [
    new NewOption(0, 'text', '', 1), 
    new NewOption(1, 'imagelocal', '', 1)
  ]);

// dropdown options
objects = [
    {type: 'text', name: 'text'},
    {type: 'imagelocal', name: 'image - local file'},
    {type: 'imageurl', name: 'image URL'}
   ( and etc.)
];

When user adds one more 'input option' (pls do not confuse 'input option' with select/options - select/options are static here) specific select/option, selected by the user earlier, is preserved on each/all dynamically added 'input option's select/options.

There is an option “unlimited scrollback buffer” which you can find under Preferences > Profiles > Terminal or you can just pump up number of lines that you want to have in history in the same place.

I had the same problem and fixed this by editing org.eclipse.wst.common.project.facet.core.xml.

In this file, I was able to change the following line

<installed facet="jst.web" version="3.1"/>

back to

<installed facet="jst.web" version="3.0"/>

That seemed to fix the problem for me.

Maybe try something like:

import matplotlib.pyplot as plt
import numpy
from scipy import stats
data = [1.5]*7 + [2.5]*2 + [3.5]*8 + [4.5]*3 + [5.5]*1 + [6.5]*8
density = stats.kde.gaussian_kde(data)
x = numpy.arange(0., 8, .1)
plt.plot(x, density(x))
plt.show()

You can easily replace gaussian_kde() by a different kernel density estimate.

You could try using "typeid".

This doesn't work for "object" name but YOU know the object name so you'll just have to store it somewhere. The Compiler doesn't care what you namned an object.

Its worth bearing in mind, though, that the output of typeid is a compiler specific thing so even if it produces what you are after on the current platform it may not on another. This may or may not be a problem for you.

The other solution is to create some kind of template wrapper that you store the class name in. Then you need to use partial specialisation to get it to return the correct class name for you. This has the advantage of working compile time but is significantly more complex.

Edit: Being more explicit

template< typename Type > class ClassName
{
public:
    static std::string name()
    {
        return "Unknown";
    }
};

Then for each class somethign liek the following:

template<> class ClassName<MyClass>
{
public:
    static std::string name()
    {
        return "MyClass";
    }
};

Which could even be macro'd as follows:

#define DefineClassName( className ) \
\
template<> class ClassName<className> \
{ \
public: \
    static std::string name() \
    { \
        return #className; \
    } \
}; \

Allowing you to, simply, do

DefineClassName( MyClass );

Finally to Get the class name you'd do the following:

ClassName< MyClass >::name();

Edit2: Elaborating further you'd then need to put this "DefineClassName" macro in each class you make and define a "classname" function that would call the static template function.

Edit3: And thinking about it ... Its obviously bad posting first thing in the morning as you may as well just define a member function "classname()" as follows:

std::string classname()
{
     return "MyClass";
}

which can be macro'd as follows:

DefineClassName( className ) \
std::string classname()  \
{ \
     return #className; \
}

Then you can simply just drop

DefineClassName( MyClass );

into the class as you define it ...

Basically, this will not work out

Format("20130423014854","yyyy-MM-dd hh:mm:ss")

the format function will only work if your string has correct format

Format (#17/04/2004#, "yyyy/mm/dd")

And you need to specify, what datatype of field [Date] is, because I can't put this value 2013-04-23 13:48:54.0 under a General Date field (I use MS access2007). You might want to view this topic: select date in between

From the Help:
IsEmpty returns True if the variable is uninitialized, or is explicitly set to Empty; otherwise, it returns False. False is always returned if expression contains more than one variable.
IsEmpty only returns meaningful information for variants.

To check if a cell is empty, you can use cell(x,y) = "".
You might eventually save time by using Range("X:Y").SpecialCells(xlCellTypeBlanks) or xlCellTypeConstants or xlCellTypeFormulas

Put this .gitignore into the folder, then git add .gitignore.

*
*/
!.gitignore

The * line tells git to ignore all files in the folder, but !.gitignore tells git to still include the .gitignore file. This way, your local repository and any other clones of the repository all get both the empty folder and the .gitignore it needs.

Edit: May be obvious but also add */ to the .gitignore to also ignore subfolders.

I've done what you suggest, and I don't see a "Renew" button either.

The following is how I got mine renewed.

I see my three profiles (companynameProfile, "Team Provisioning Profile", and productnameProfile). THe first and third are going to expire within a couple of weeks. The second (and only the second) is flagged as "managed by Xcode". The profile names appear in a table with columns labelled: "Provisioning Profile", App ID, Status, and Actions. The status for all three is "Active". First 1 and 3, the Actions column has a "Download" button, and an "Edit" link. For 2, gthe Actions column has only the "Download" button.

There is no "Renew" (or "Refresh") button / link anywhere (and I did a view-source and searched that too :)

So, I thought...click on "Edit" on #3 ... two choices pop-up: Modify and Duplicate. I chose "Modify"

There is still no renew/refresh ... but there is a "Submit" button ... which doesn't work (turns out its sort of grayed out, but that's not at all obvious...bad UI design).

I discovered that if I change something on the screen (in my case, I selected a previously unused device), "Submit" darkens (becomes available). Click on "Submit". You're quietly (another UI problem :) taken back to the prior page, and the "Download" and "Edit" buttons are gone, and the status column should say "Pending"!

After awhile, I refreshed the window (reloaded) (don't know if it would have auto-refreshed) ... and saw that the status column had changed to "Active".

Now...I downloaded the new profile (the one that the darn page doesn't tell you is new, and doesn't LIST THE EXPIRATION DATE so you could tell yourself ... third UI flaw already :)

I downloaded the profile, deleted the old profile from the list in the Organizer window of Xcode, then dragged the new one into the Organizer window of Xcode, and ... voila, Organizer shows a new expiration date (of about 3 months from today).

Hope that helps,

You are missing # hash character before id selectors, this should work:

$(document).ready(function() {
    $("#div2").hide();

    $("#preview").click(function() {
      $("#div1").hide();
      $("#div2").show();
    });

});

To each his own but the right way to code this is to rename the columns inserting underscore so there are no gaps. This will ensure zero errors when coding. When printing the column names for public display you could search-and-replace to replace the underscore with a space.

(n & 1) will check if 'n' is odd or even, this is similar to (n%2).

1. In case 'n' is odd (n & 1) will return true/1;

2. Else it will return back false/0;

The '>>' in (n>>=1) is a bitwise operator called "Right shift", this operator will modify the value of 'n', the formula is:

(n >>= m) => (n = n>>m) => (n = n/2^m)

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

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

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

Another, less convenient, way to do it is to use Decimal class:

from decimal import Decimal
pos_inf = Decimal('Infinity')
neg_inf = Decimal('-Infinity')

There are cases when you are converting ENUM to a string or converting string to enum in case where you are writing/reading to/from a file.

You sometimes need to make one of the values default to cover errors made by manually editing files.

switch(textureMode)
{
case ModeTiled:
default:
    // write to a file "tiled"
    break;

case ModeStretched:
    // write to a file "stretched"
    break;
}

No; instances of class File represent a path in a filesystem. Therefore, you can use that function only with a file. But perhaps there is an overload that takes an InputStream instead?

Not sure what language you're using (you didn't specify), but you should be able to "escape" the quotation mark character with a backslash: "\"ROM\""

Late answer but, after PHP 5.3 could be so;

$array = array(1, 2, 3, 4, 5);
$array = array_values(array_filter($array, function($v) {
    return !($v == 1 || $v == 2);
}));
print_r($array);

Via Type.GetType you can get the type information. You can use this class to get the method information and then invoke the method (for static methods, leave the first parameter null).

You might also need the Assembly name to correctly identify the type.

If the type is in the currently executing assembly or in Mscorlib.dll, it is sufficient to supply the type name qualified by its namespace.

I had the same problem but solved it in this way:

df = pd.read_csv('your-array.csv', skiprows=[0])

i had got the same error. Actually i tried to override the flutter Old SDK Package with new Updated Package. so that error occurred.

i opened flutter sdk directory with VS Code and cleaned the project

use this code in VSCode cmd

git clean -dxf

then use git pull

    select date_format(date_parse(t.payDate,'%Y-%m-%d %H:%i:%S'),'%Y-%m-%d') as payDate 
    from testTable  t 
    where t.paydate is not null and t.paydate <> '';

@echo off
start %1

or if needed to escape the characters -

@echo off
start %%1

I found that it would work to reset the month to January for both dates (the provided date and the present):

> moment("02/26/1978", "MM/DD/YYYY").month(0).from(moment().month(0))

$("#closeLink").click(closeIt);

Let's say you want to call your function passing some args to it i.e., closeIt(1, false). Then, you should build an anonymous function and call closeIt from it.

$("#closeLink").click(function() {
    closeIt(1, false);
});

You could try replacing it with 1002 or issuing your initialization query right after opening a connection.

In my opinion, it would be technically possible to convert the CLI Bytecode to Dalvik, and to write wrapper classes for some core features such as Collections, File access, etc., even it would be hard work.

But a .NET desktop application ran on android would feel alien, as it would have a classic Windows-Like GUI which is not very usable on a touch device. If, on the other hand, you were to code an android-like GUI in .NET, you would need another set of wrappers (notice that wrapping is just the other way round opposed to the wrappers mentioned above).

I'm not sure if a .NET mobile application would feel native on android, but I'd guess it wouldn't.

Maybe you're interestend in another approach: You can write your application in the Java language. You can then compile it to .NET via Microsoft J# (I know it's discontinued but you can still download and use it) and use the same Java code on android. Again, that's for the core classes aka business logic and again you would have to write tow GUIs. Maybe you can tages J2ME as well, which you will not be able to do if you use .NET.

If you look at the scope of the variable 'hoursWorked' you will see that it is a member of the class (declared as private int)

The two variables you are having trouble with are passed as parameters to the constructor.

The error message is because 'hours' is out of scope in the setter.

I would use:

awk 'FNR <= 1' file_*.txt

As @Kusalananda points out there are many ways to capture the first line in command line but using the head -n 1 may not be the best option when using wildcards since it will print additional info. Changing 'FNR == i' to 'FNR <= i' allows to obtain the first i lines.

For example, if you have n files named file_1.txt, ... file_n.txt:

awk 'FNR <= 1' file_*.txt

hello
...
bye

But with head wildcards print the name of the file:

head -1 file_*.txt

==> file_1.csv <==
hello
...
==> file_n.csv <==
bye

You can write a VBScript script to get the file version info:

VersionInfo.vbs

set args = WScript.Arguments
Set fso = CreateObject("Scripting.FileSystemObject")
WScript.Echo fso.GetFileVersion(args(0))
Wscript.Quit

You can call this from the command line like this:

cscript //nologo VersionInfo.vbs C:\Path\To\MyFile.dll

While I respect the answer from qkrijger explaining how you can work around this issue I think there is a lot more we can learn about what's going on here ...

To actually answer your question of "why" ... I think it would for helpful for you to understand how the docker stop command works and that all processes should be shutdown cleanly to prevent problems when you try to restart them (file corruption etc).

Problem: What if docker did start SSH from it's command and started RabbitMQ from your Docker file? "The docker stop command attempts to stop a running container first by sending a SIGTERM signal to the root process (PID 1) in the container." Which process is docker tracking as PID 1 that will get the SIGTERM? Will it be SSH or Rabbit?? "According to the Unix process model, the init process -- PID 1 -- inherits all orphaned child processes and must reap them. Most Docker containers do not have an init process that does this correctly, and as a result their containers become filled with zombie processes over time."

Answer: Docker simply takes that last CMD as the one that will get launched as the root process with PID 1 and get the SIGTERM from docker stop.

Suggested solution: You should use (or create) a base image specifically made for running more than one service, such as phusion/baseimage

It should be important to note that tini exists exactly for this reason, and as of Docker 1.13 and up, tini is officially part of Docker, which tells us that running more than one process in Docker IS VALID .. so even if someone claims to be more skilled regarding Docker, and insists that you absurd for thinking of doing this, know that you are not. There are perfectly valid situations for doing so.

SOAP (Simple Object Access Protocol) is a messaging protocol that allows programs that run on disparate operating systems to communicate using http and xml.

The first argument to printf() is always a string value, known as a format control string. This string may be regular text, such as

printf("Hello, World\n"); // \n indicates a newline character

or

char greeting[] = "Hello, World\n";
printf(greeting);

This string may also contain one or more conversion specifiers; these conversion specifiers indicate that additional arguments have been passed to printf(), and they specify how to format those arguments for output. For example, I can change the above to

char greeting[] = "Hello, World";
printf("%s\n", greeting);

The "%s" conversion specifier expects a pointer to a 0-terminated string, and formats it as text.

For signed decimal integer output, use either the "%d" or "%i" conversion specifiers, such as

printf("%d\n", addNumber(a,b));

You can mix regular text with conversion specifiers, like so:

printf("The result of addNumber(%d, %d) is %d\n", a, b, addNumber(a,b));

Note that the conversion specifiers in the control string indicate the number and types of additional parameters. If the number or types of additional arguments passed to printf() don't match the conversion specifiers in the format string then the behavior is undefined. For example:

printf("The result of addNumber(%d, %d) is %d\n", addNumber(a,b));

will result in anything from garbled output to an outright crash.

There are a number of additional flags for conversion specifiers that control field width, precision, padding, justification, and types. Check your handy C reference manual for a complete listing.

You can also sort your array and then use array.first or array.last

You can use: Thread.currentThread().isAlive();. Returns true if this thread is alive; false otherwise.

In WPF RelativeSource binding exposes three properties to set:

1. Mode: This is an enum that could have four values:

a. PreviousData(value=0): It assigns the previous value of the property to the bound one

b. TemplatedParent(value=1): This is used when defining the templates of any control and want to bind to a value/Property of the control.

For example, define ControlTemplate:

  <ControlTemplate>
        <CheckBox IsChecked="{Binding RelativeSource={RelativeSource TemplatedParent}, Path=Value, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" />
 </ControlTemplate>

c. Self(value=2): When we want to bind from a self or a property of self.

For example: Send checked state of checkbox as CommandParameter while setting the Command on CheckBox

<CheckBox ...... CommandParameter="{Binding RelativeSource={RelativeSource Self},Path=IsChecked}" />

d. FindAncestor(value=3): When want to bind from a parent control in Visual Tree.

For example: Bind a checkbox in records if a grid,if header checkbox is checked

<CheckBox IsChecked="{Binding RelativeSource={RelativeSource Mode=FindAncestor, AncestorType={x:Type iDP:XamDataGrid}}, Path=DataContext.IsHeaderChecked, Mode=TwoWay}" />

2. AncestorType: when mode is FindAncestor then define what type of ancestor

RelativeSource={RelativeSource Mode=FindAncestor, AncestorType={x:Type iDP:XamDataGrid}}

3. AncestorLevel: when mode is FindAncestor then what level of ancestor (if there are two same type of parent in visual tree)

RelativeSource={RelativeSource Mode=FindAncestor, AncestorType={x:Type iDP:XamDataGrid, AncestorLevel=1}}

Above are all use-cases for RelativeSource binding.

One can simply use

INSERT INTO MY_TABLE(MY_TIMESTAMP_FIELD)
VALUES (TIMESTAMP '2019-02-15 13:22:11.871+02:00');

This way you won't have to worry about date format string, just use default timestamp format.

Do you have a smart phone? Is there one big app or lots of little ones? Does one app reply upon another? Can you use one app while installing, updating, and/or uninstalling another? That each app is self-contained is high cohesion. That each app is independent of the others is low coupling. DevOps favours this architecture because it means you can do discrete continuous deployment without disrupting the system entire.

We have the following string which is a valid JSON ...

Clearly the JSON parser disagrees!

However, the exception says that the error is at "line 1: column 9", and there is no "http" token near the beginning of the JSON. So I suspect that the parser is trying to parse something different than this string when the error occurs.

You need to find what JSON is actually being parsed. Run the application within a debugger, set a breakpoint on the relevant constructor for JsonParseException ... then find out what is in the ByteArrayInputStream that it is attempting to parse.

With Spring 4.1 and above, you can return pretty much anything (such as pictures, pdfs, documents, jars, zips, etc) quite simply without any extra dependencies. For example, the following could be a method to return a user's profile picture from MongoDB GridFS:

@RequestMapping(value = "user/avatar/{userId}", method = RequestMethod.GET)
@ResponseBody
public ResponseEntity<InputStreamResource> downloadUserAvatarImage(@PathVariable Long userId) {
    GridFSDBFile gridFsFile = fileService.findUserAccountAvatarById(userId);

    return ResponseEntity.ok()
            .contentLength(gridFsFile.getLength())
            .contentType(MediaType.parseMediaType(gridFsFile.getContentType()))
            .body(new InputStreamResource(gridFsFile.getInputStream()));
}

The things to note:

• ResponseEntity with InputStreamResource as a return type

• ResponseEntity builder style creation

With this method you dont have to worry about autowiring in the HttpServletResponse, throwing an IOException or copying stream data around.

That heavily depends on the structure of the search tree and the number and location of solutions (aka searched-for items).

• If you know a solution is not far from the root of the tree, a breadth first search (BFS) might be better.

• If the tree is very deep and solutions are rare, depth first search (DFS) might take an extremely long time, but BFS could be faster.

• If the tree is very wide, a BFS might need too much memory, so it might be completely impractical.

• If solutions are frequent but located deep in the tree, BFS could be impractical.

• If the search tree is very deep you will need to restrict the search depth for depth first search (DFS), anyway (for example with iterative deepening).

But these are just rules of thumb; you'll probably need to experiment.

Another issue is parallelism: if you want to parallelize BFS you would need a shared datastructure between threads, which is a bad thing. DFS might be easier to distribute even between connected machines if you don't insist on the exact order of visiting the nodes.

2. Configure you git to add extra header with your private token:

   $ git config --global http.extraheader "PRIVATE-TOKEN: YOUR_PRIVATE_TOKEN
   

3. Configure your git to convert requests from http to ssh:

   $ git config --global url."[email protected]:".insteadOf "https://gitlab.mycompany.com/"
   

4. Finally you can use your go get normally:

   $ go get gitlab.com/company/private_repo
   

You might need a ~/.ssh/config:

Host gitlab.YOURDOMAIN.DOMAIN
    Port 1111
    IdentityFile ~/.ssh/id_rsa

and then you can use git clone git@DOMAINandREPOSITORY. This means you always use the user git.

For the allowed characters you can use

^[a-zA-Z0-9~@#$^*()_+=[\]{}|\\,.?: -]*$

to validate a complete string that should consist of only allowed characters. Note that - is at the end (because otherwise it'd be a range) and a few characters are escaped.

For the invalid characters you can use

[<>'"/;`%]

to check for them.

To combine both into a single regex you can use

^(?=[a-zA-Z0-9~@#$^*()_+=[\]{}|\\,.?: -]*$)(?!.*[<>'"/;`%])

but you'd need a regex engine that allows lookahead.

First off, Daniel's answer is the correct, safe option.

For the specific case of changing from SQL_ASCII to something else, you can cheat and simply poke the pg_database catalogue to reassign the database encoding. This assumes you've already stored any non-ASCII characters in the expected encoding (or that you simply haven't used any non-ASCII characters).

Then you can do:

update pg_database set encoding = pg_char_to_encoding('UTF8') where datname = 'thedb'

This will not change the collation of the database, just how the encoded bytes are converted into characters (so now length('£123') will return 4 instead of 5). If the database uses 'C' collation, there should be no change to ordering for ASCII strings. You'll likely need to rebuild any indices containing non-ASCII characters though.

Caveat emptor. Dumping and reloading provides a way to check your database content is actually in the encoding you expect, and this doesn't. And if it turns out you did have some wrongly-encoded data in the database, rescuing is going to be difficult. So if you possibly can, dump and reinitialise.

For those having the percentages in a pandas Series, here is my implemantation of the Largest remainder method (as in Varun Vohra's answer), where you can even select the decimals to which you want to round.

import numpy as np

def largestRemainderMethod(pd_series, decimals=1):

    floor_series = ((10**decimals * pd_series).astype(np.int)).apply(np.floor)
    diff = 100 * (10**decimals) - floor_series.sum().astype(np.int)
    series_decimals = pd_series - floor_series / (10**decimals)
    series_sorted_by_decimals = series_decimals.sort_values(ascending=False)

    for i in range(0, len(series_sorted_by_decimals)):
        if i < diff:
            series_sorted_by_decimals.iloc[[i]] = 1
        else:
            series_sorted_by_decimals.iloc[[i]] = 0

    out_series = ((floor_series + series_sorted_by_decimals) / (10**decimals)).sort_values(ascending=False)

    return out_series

You can read the post request parameter with jQuery-PostCapture(@ssut/jQuery-PostCapture).

PostCapture plugin is consisted of some tricks.

When you are click the submit button, the onsubmit event will be dispatched.

At the time, PostCapture will be serialize form data and save to html5 localStorage(if available) or cookie storage.

If your environment doesn't allow overwriting with >, use pipe | and tee instead as follows:

echo "text" | tee 'Users/Name/Desktop/TheAccount.txt'

Note this will also print to the stdout. In case this is unwanted, you can redirect the output to /dev/null as follows:

echo "text" | tee 'Users/Name/Desktop/TheAccount.txt' > /dev/null

Try something like gem uninstall rjb --version 1.3.4.

In server applications the stacktrace blows up your stdout/stderr file. It may become larger and larger and is filled with useless data because usually you have no context and no timestamp and so on.

e.g. catalina.out when using tomcat as container

If you run your playbook with ansible-playbook -vvv you'll see the actual command being run, so you can check whether the key is actually being included in the ssh command (and you might discover that the problem was the wrong username rather than the missing key).

I agree with Brian's comment above (and zigam's edit) that the vars section is too late. I also tested including the key in the on-the-fly definition of the host like this

# fails
- name: Add all instance public IPs to host group
  add_host: hostname={{ item.public_ip }} groups=ec2hosts ansible_ssh_private_key_file=~/.aws/dev_staging.pem
  loop: "{{ ec2.instances }}"

but that fails too.

So this is not an answer. Just some debugging help and things not to try.

Please bear in mind that the formatting of the date is independent of the storage. If it's essential to you that the date is stored in that format you will need to either define a custom data type or store it as a string. Then you can use a combination of extract, typecasting and concatenation to get that format.

However, I suspect that you want to store a date and get the format on output. So, something like this will do the trick for you:

    CREATE TABLE my_table
    (
    id serial PRIMARY KEY not null,
    my_date date not null default CURRENT_DATE
    );

(CURRENT_DATE is basically a synonym for now() and a cast to date).

(Edited to use to_char).

Then you can get your output like:

SELECT id, to_char(my_date, 'yyyymm') FROM my_table;

Now, if you did really need to store that field as a string and ensure the format you could always do:

CREATE TABLE my_other_table
(
id serial PRIMARY KEY not null,
my_date varchar(6) default to_char(CURRENT_DATE, 'yyyymm')
);

There is no HTTP status code 0. What you see is a 0 returned by the API/library that you are using. You will have to check the documentation for that.

The Default Expiration Period for Session is 20 Minutes.

You can update sessionstate and configure the minutes under timeout

<sessionState 
timeout="30">
</sessionState>

Ahah! Cade is on the money.

An artifact in TOAD prints \r\n as two placeholder 'blob' characters, but prints a single \r also as two placeholders. The 1st step toward a solution is to use ..

REPLACE( col_name, CHR(13) || CHR(10) )

.. but I opted for the slightly more robust ..

REPLACE(REPLACE( col_name, CHR(10) ), CHR(13) )

.. which catches offending characters in any order. My many thanks to Cade.

It means parent/child

Use x86 images and download "Intel Hardware Accelerated Execution Manager" from the sdk manager.

Your emulator will be super fast!

It shouldn't matter which is faster. If it does matter then benchmark it using your real code and see for yourself.

The answers to this other question might be useful as well: How to write more efficient code

Hehe, curious. I think this is an "intentianal bug", so to speak.

The underlying reason is how the Integer class is written. Basically, parseInt is "optimized" for positive numbers. When it parses the string, it builds the result cumulatively, but negated. Then it flips the sign of the end-result.

Example:

66 = 0x42

parsed like:

4*(-1) = -4
-4 * 16 = -64 (hex 4 parsed)

-64 - 2 = -66 (hex 2 parsed)

return -66 * (-1) = 66

Now, let's look at your example FFFF8000

16*(-1) = -16 (first F parsed)
-16*16 = -256 

-256 - 16 = -272 (second F parsed)
-272 * 16 = -4352 

-4352 - 16 = -4368 (third F parsed)
-4352 * 16 = -69888

-69888 - 16 = -69904 (forth F parsed)
-69904 * 16 = -1118464 

-1118464 - 8 = -1118472 (8 parsed)
-1118464 * 16 = -17895552 

-17895552 - 0 = -17895552 (first 0 parsed)
Here it blows up since -17895552 < -Integer.MAX_VALUE / 16 (-134217728). 
Attempting to execute the next logical step in the chain (-17895552 * 16)
would cause an integer overflow error.

Edit (addition): in order for the parseInt() to work "consistently" for -Integer.MAX_VALUE <= n <= Integer.MAX_VALUE, they would have had to implement logic to "rotate" when reaching -Integer.MAX_VALUE in the cumulative result, starting over at the max-end of the integer range and continuing downwards from there. Why they did not do this, one would have to ask Josh Bloch or whoever implemented it in the first place. It might just be an optimization.

However,

Hex=Integer.toHexString(Integer.MAX_VALUE);
System.out.println(Hex);
System.out.println(Integer.parseInt(Hex.toUpperCase(), 16));

works just fine, for just this reason. In the sourcee for Integer you can find this comment.

// Accumulating negatively avoids surprises near MAX_VALUE

It mostly depends on the (other) activity in the database. Operations like this effectively freeze the entire database for other sessions. Another consideration is the datamodel and the presence of constraints,triggers, etc.

My first approach is always: create a (temp) table with a structure similar to the target table (create table tmp AS select * from target where 1=0), and start by reading the file into the temp table. Then I check what can be checked: duplicates, keys that already exist in the target, etc.

Then I just do a "do insert into target select * from tmp" or similar.

If this fails, or takes too long, I abort it and consider other methods (temporarily dropping indexes/constraints, etc)

Make a drawable file, striking_text.xml

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_pressed="false">
        <shape android:shape="line">
            <stroke android:width="1dp" android:color="@android:color/holo_red_dark" />
        </shape>
    </item>
</selector>

layout xml

 <TextView
            ....
            ....
            android:background="@drawable/striking_text"
            android:foreground="@drawable/striking_text"
            android:text="69$"
           />

If your min SDK below API level 23 just use the background or just put the background and foreground in the Textview then the android studio will show an error that says create a layout file for API >23 after that remove the android:foreground="@drawable/stricking_text" from the main layout

Output look like this:

    <script type="text/javascript">
<!-- 
function newPage(num) {
var url=new Array();
url[0]="http://www.htmlforums.com";
url[1]="http://www.codingforums.com.";
url[2]="http://www.w3schools.com";
url[3]="http://www.webmasterworld.com";
window.location=url[num];``
}
// -->
</script>
</head>
<body>
<form action="#">
<div id="container">
<input class="butts" type="button" value="htmlforums" onclick="newPage(0)"/>
<input class="butts" type="button" value="codingforums" onclick="newPage(1)"/>
<input class="butts" type="button" value="w3schools" onclick="newPage(2)"/>
<input class="butts" type="button" value="webmasterworld" onclick="newPage(3)"/>
</div>
</form>
</body>

Here's the other way, it's simpler than the other one.

<input id="inp" type="button" value="Home Page" onclick="location.href='AdminPage.jsp';" />

It's simpler.

I think we better adopt a new file inclusion syntax (so won't mess up with code blocks, I think the C style inclusion is totally wrong), and I wrote a small tool in Perl, naming cat.pl, because it works like cat (cat a.txt b.txt c.txt will merge three files), but it merges files in depth, not in width. How to use?

$ perl cat.pl <your file>

The syntax in detail is:

• recursive include files: @include <-=path=
• just include one: %include <-=path=

It can properly handle file inclusion loops (if a.txt <- b.txt, b.txt <- a.txt, then what you expect?).

Example:

a.txt:

a.txt

    a <- b

    @include <-=b.txt=

a.end

b.txt:

b.txt

    b <- a

    @include <-=a.txt=

b.end

perl cat.pl a.txt > c.txt, c.txt:

a.txt

    a <- b

    b.txt

        b <- a

        a.txt

            a <- b

            @include <-=b.txt= (note:won't include, because it will lead to infinite loop.)

        a.end

    b.end

a.end

I also wrote a Java version having an identical effect (not the same, but close).

First of all, shouldn't there be a CustomerId in the Invoices table? As it is, You can't perform this query for Invoices that have no payments on them as yet. If there are no payments on an invoice, that invoice will not even show up in the ouput of the query, even though it's an outer join...

Also, When a customer makes a payment, how do you know what Invoice to attach it to ? If the only way is by the InvoiceId on the stub that arrives with the payment, then you are (perhaps inappropriately) associating Invoices with the customer that paid them, rather than with the customer that ordered them... . (Sometimes an invoice can be paid by someone other than the customer who ordered the services)

Maybe it can be useful for someone:

// Printing the SQL with real values
$vals = $query->getFlattenedParams();
foreach(explode('?', $query->getSqlQuery()) as $i => $part) {
    $sql = (isset($sql) ? $sql : null) . $part;

}

echo $sql;

No.

Sometimes you can quote the filename.

"C:\Program Files\Something"

Some programs will tolerate the quotes. Since you didn't provide any specific program, it's impossible to tell if quotes will work for you.

To add to the confusion around Q-Q plots and probability plots in the Python and R worlds, this is what the SciPy manual says:

"probplot generates a probability plot, which should not be confused with a Q-Q or a P-P plot. Statsmodels has more extensive functionality of this type, see statsmodels.api.ProbPlot."

If you try out scipy.stats.probplot, you'll see that indeed it compares a dataset to a theoretical distribution. Q-Q plots, OTOH, compare two datasets (samples).

R has functions qqnorm, qqplot and qqline. From the R help (Version 3.6.3):

qqnorm is a generic function the default method of which produces a normal QQ plot of the values in y. qqline adds a line to a “theoretical”, by default normal, quantile-quantile plot which passes through the probs quantiles, by default the first and third quartiles.

qqplot produces a QQ plot of two datasets.

In short, R's qqnorm offers the same functionality that scipy.stats.probplot provides with the default setting dist=norm. But the fact that they called it qqnorm and that it's supposed to "produce a normal QQ plot" may easily confuse users.

Finally, a word of warning. These plots don't replace proper statistical testing and should be used for illustrative purposes only.

'sp_removedbreplication' didn't solve the issue for me as SQL just returned saying that the Database wasn't part of a replication...

Basically I had to create a replication, reset all of the replication pointers to Zero; then delete the replication I had just made. i.e.

Execute SP_ReplicationDbOption {DBName},Publish,true,1
GO
Execute sp_repldone @xactid = NULL, @xact_segno = NULL, @numtrans = 0, @time = 0, @reset = 1
GO
DBCC ShrinkFile({LogFileName},0)
GO
Execute SP_ReplicationDbOption {DBName},Publish,false,1
GO

DECLARE @id INT 
SET @id = 0 
UPDATE cartemp
SET @id = CarmasterID = @id + 1 
GO

as PHP relies on server, the real-time location cant be provided only static location can be provided it is better to avoid to rely on the JS for location rather than using php. But there is a need to post the js data to php so that it can be easily be accesible to program on server

If there are multiple views spanning a LinearLayout, then layout_weight gives them each a proportional size. A view with a bigger layout_weight value "weighs" more, so it gets a bigger space.

Here is an image to make things more clear.

Theory

The term layout weight is related to the concept of weighted average in math. It is like in a college class where homework is worth 30%, attendance is worth 10%, the midterm is worth 20%, and the final is worth 40%. Your scores for those parts, when weighted together, give you your total grade.

It is the same for layout weight. The Views in a horizontal LinearLayout can each take up a certain percentage of the total width. (Or a percentage of the height for a vertical LinearLayout.)

The Layout

The LinearLayout that you use will look something like this:

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="horizontal">

    <!-- list of subviews -->

</LinearLayout>

Note that you must use layout_width="match_parent" for the LinearLayout. If you use wrap_content, then it won't work. Also note that layout_weight does not work for the views in RelativeLayouts (see here and here for SO answers dealing with this issue).

The Views

Each view in a horizontal LinearLayout looks something like this:

<Button
    android:layout_width="0dp"
    android:layout_height="wrap_content"
    android:layout_weight="1" />

Note that you need to use layout_width="0dp" together with layout_weight="1". Forgetting this causes many new users problems. (See this article for different results you can get by not setting the width to 0.) If your views are in a vertical LinearLayout then you would use layout_height="0dp", of course.

In the Button example above I set the weight to 1, but you can use any number. It is only the total that matters. You can see in the three rows of buttons in the first image that I posted, the numbers are all different, but since the proportions are the same, the weighted widths don't change in each row. Some people like to use decimal numbers that have a sum of 1 so that in a complex layout it is clear what the weight of each part is.

One final note. If you have lots of nested layouts that use layout_weight, it can be bad for performance.

Extra

Here is the xml layout for the top image:

Using configure() method two times is responsible the problem for me. Instead of using like this :

    Configuration configuration = new Configuration().configure();
    configuration.configure("/main/resources/hibernate.cfg.xml");

Now, I am using like this, problem does not exist anymore.

    Configuration configuration = new Configuration();
    configuration.configure("/main/resources/hibernate.cfg.xml");

P.S: My hibernate.cfg.xml file is located at "src/main/resources/hibernate.cfg.xml",too. The code belove works for me. at hibernate-5

public class HibernateUtil {

 private static SessionFactory sessionFactory ;


 static {
     try{
    Configuration configuration = new Configuration();
    configuration.configure("/main/resources/hibernate.cfg.xml");
    StandardServiceRegistryBuilder builder = new StandardServiceRegistryBuilder().applySettings(configuration.getProperties());
    sessionFactory = configuration.buildSessionFactory(builder.build());
 }
     catch(Exception e){
         e.printStackTrace();
     }
     }

public static SessionFactory getSessionFactory() {
    return sessionFactory;
}
}  

You should generally NOT ignore the exception. Take a look at the following paper:

Don't swallow interrupts

Sometimes throwing InterruptedException is not an option, such as when a task defined by Runnable calls an interruptible method. In this case, you can't rethrow InterruptedException, but you also do not want to do nothing. When a blocking method detects interruption and throws InterruptedException, it clears the interrupted status. If you catch InterruptedException but cannot rethrow it, you should preserve evidence that the interruption occurred so that code higher up on the call stack can learn of the interruption and respond to it if it wants to. This task is accomplished by calling interrupt() to "reinterrupt" the current thread, as shown in Listing 3. At the very least, whenever you catch InterruptedException and don't rethrow it, reinterrupt the current thread before returning.

public class TaskRunner implements Runnable {
    private BlockingQueue<Task> queue;

    public TaskRunner(BlockingQueue<Task> queue) { 
        this.queue = queue; 
    }

    public void run() { 
        try {
             while (true) {
                 Task task = queue.take(10, TimeUnit.SECONDS);
                 task.execute();
             }
         }
         catch (InterruptedException e) { 
             // Restore the interrupted status
             Thread.currentThread().interrupt();
         }
    }
}

After reading the answers here I think I can provide a new point of view: if the purpose of this question is to know if the path to a certain executable file exists in %PATH% and if not, insert it (and this is the only reason to do that, I think), then it may solved in a slightly different way: "How to check if the directory of a certain executable program exist in %PATH%"? This question may be easily solved this way:

for %%p in (programname.exe) do set "progpath=%%~$PATH:p"
if not defined progpath (
   rem The path to programname.exe don't exist in PATH variable, insert it:
   set "PATH=%PATH%;C:\path\to\progranname"
)

If you don't know the extension of the executable file, just review all of them:

set "progpath="
for %%e in (%PATHEXT%) do (
   if not defined progpath (
      for %%p in (programname.%%e) do set "progpath=%%~$PATH:p"
   )
)

No, but the 32-bit version runs just fine on 64-bit Windows.

This is one of those things that can be difficult to search for if you don't already know where to look.

[ is actually a command, not part of the bash shell syntax as you might expect. It happens to be a Bash built-in command, so it's documented in the Bash manual.

There's also an external command that does the same thing; on many systems, it's provided by the GNU Coreutils package.

[ is equivalent to the test command, except that [ requires ] as its last argument, and test does not.

Assuming the bash documentation is installed on your system, if you type info bash and search for 'test' or '[' (the apostrophes are part of the search), you'll find the documentation for the [ command, also known as the test command. If you use man bash instead of info bash, search for ^ *test (the word test at the beginning of a line, following some number of spaces).

Following the reference to "Bash Conditional Expressions" will lead you to the description of -ne, which is the numeric inequality operator ("ne" stands for "not equal). By contrast, != is the string inequality operator.

You can also find bash documentation on the web.

• Bash reference
• Bourne shell builtins (including test and [)
• Bash Conditional Expressions -- (Scroll to the bottom; -ne is under "arg1 OP arg2")
• POSIX documentation for test

The official definition of the test command is the POSIX standard (to which the bash implementation should conform reasonably well, perhaps with some extensions).

This method has the benefit of allowing you to rank by a different column, and not trashing the other data. It's quite useful in a situation where you are trying to list orders with a column for items, listing the heaviest first.

Add a literal space, or a tab:

public void displayCustomerInfo() {
    System.out.println(Name + " " + Income);

    // or a tab
    System.out.println(Name + "\t" + Income);
}
