The difficulty with DDD samples is that they're often very domain specific and the technical implementation of the resulting system doesn't always show the design decisions and transitions that were made in modelling the domain, which is really at the core of DDD. DDD is much more about the process than it is the code. (as some say, the best DDD sample is the book itself!)

That said, a well commented sample app should at least reveal some of these decisions and give you some direction in terms of matching up your domain model with the technical patterns used to implement it.

You haven't specified which language you're using, but I'll give you a few in a few different languages:

DDDSample - a Java sample that reflects the examples Eric Evans talks about in his book. This is well commented and shows a number of different methods of solving various problems with separate bounded contexts (ie, the presentation layer). It's being actively worked on, so check it regularly for updates.

dddps - Tim McCarthy's sample C# app for his book, .NET Domain-Driven Design with C#

S#arp Architecture - a pragmatic C# example, not as "pure" a DDD approach perhaps due to its lack of a real domain problem, but still a nice clean approach.

With all of these sample apps, it's probably best to check out the latest trunk versions from SVN/whatever to really get an idea of the thinking and technology patterns as they should be updated regularly.

DAO is an abstraction of data persistence.
Repository is an abstraction of a collection of objects.

DAO would be considered closer to the database, often table-centric.
Repository would be considered closer to the Domain, dealing only in Aggregate Roots.

Repository could be implemented using DAO's, but you wouldn't do the opposite.

Also, a Repository is generally a narrower interface. It should be simply a collection of objects, with a Get(id), Find(ISpecification), Add(Entity).

A method like Update is appropriate on a DAO, but not a Repository - when using a Repository, changes to entities would usually be tracked by separate UnitOfWork.

It does seem common to see implementations called a Repository that is really more of a DAO, and hence I think there is some confusion about the difference between them.

EDIT:

As this seem to be a top result on Google and my answer below is not, please refer to this much better answer:

OLD ANSWER (not so complete :))

In order to create good software, you have to know what that software is all about. You cannot create a banking software system unless you have a good understanding of what banking is all about, one must understand the domain of banking.

From: Domain Driven Design by Eric Evans.

This book does a pretty good job of describing DDD.

Couldn't resist throwing this out there, old as this thread is... Usually when the need arises to iterate through each of the files in PATH, all you really want to do is find a particular file... If that's the case, this one-liner will spit out the first directory it finds your file in:

(ex: looking for java.exe)

for %%x in (java.exe) do echo %%~dp$PATH:x

Using regex, the result is in $matches[1]:

$str = "test.txt ; 131 136 80 89 119 17 60 123 210 121 188 42 136 200 131 198"
$str -match "^(.*?)\s\;"
$matches[1]
test.txt

It is probably the h1 tag causing the problem. Applying margin: 0; should fix the problem.

But you should use a CSS reset for every new project to eliminate browser consistencies and problems like yours. Probably the most famous one is Eric Meyer's: http://meyerweb.com/eric/tools/css/reset/

'^(part1|part2|part1,part2)$'

does it work?

Use a custom Listview.

You can also customize how row looks by having a custom background. activity_main.xml

Inflate a custom layout. Use a view holder for smooth scrolling and performance.

http://www.youtube.com/watch?v=wDBM6wVEO70. The talk is about listview performance by android developers.

To avoid just the permission denied warnings, tell find to ignore the unreadable files by pruning them from the search. Add an expression as an OR to your find, such as

find / \! -readable -prune -o -name '*.jbd' -ls

This mostly says to (match an unreadable file and prune it from the list) OR (match a name like *.jbd and display it [with ls]). (Remember that by default the expressions are AND'd together unless you use -or.) You need the -ls in the second expression or else find may add a default action to show either match, which will also show you all the unreadable files.

But if you're looking for real files on your system, there is usually no reason to look in /dev, which has many many files, so you should add an expression that excludes that directory, like:

find / -mount \! -readable -prune  -o  -path /dev -prune  -o  -name '*.jbd' -ls

So (match unreadable file and prune from list) OR (match path /dev and prune from list) OR (match file like *.jbd and display it).

You can probably safely ignore the error messages in this case. Failing to add a comment to the public schema and installing plpgsql (which should already be installed) aren't going to cause any real problems.

However, if you want to do a complete re-install you'll need a user with appropriate permissions. That shouldn't be the user your application routinely runs as of course.

If you know your file will live where your classes are, that directory will be on your classpath. In that case, you can be sure that this solution will solve your problem:

URL path = ClassLoader.getSystemResource("myFile.txt");
if(path==null) {
     //The file was not found, insert error handling here
}
File f = new File(path.toURI());

reader = new BufferedReader(new FileReader(f));

In Ubuntu and Debian, you can apt-get install moreutils. This contains a utility called mispipe that returns the exit status of the first command in the pipe.

Is there any way to access to the $VAR by just executing export.bash without sourcing it ?

Quick answer: No.

But there are several possible workarounds.

The most obvious one, which you've already mentioned, is to use source or . to execute the script in the context of the calling shell:

$ cat set-vars1.sh 
export FOO=BAR
$ . set-vars1.sh 
$ echo $FOO
BAR

Another way is to have the script, rather than setting an environment variable, print commands that will set the environment variable:

$ cat set-vars2.sh
#!/bin/bash
echo export FOO=BAR
$ eval "$(./set-vars2.sh)"
$ echo "$FOO"
BAR

A third approach is to have a script that sets your environment variable(s) internally and then invokes a specified command with that environment:

$ cat set-vars3.sh
#!/bin/bash
export FOO=BAR
exec "$@"
$ ./set-vars3.sh printenv | grep FOO
FOO=BAR

This last approach can be quite useful, though it's inconvenient for interactive use since it doesn't give you the settings in your current shell (with all the other settings and history you've built up).

FYI - I could not find WcfTestClient.exe under any of the listed file paths. It turns out it needed to be installed by Visual Studio Installer. When you launch the installer and modify your version of VS, make sure Windows Communication Foundation is checked under Optional. It may seem obvious, but it wasn't to me and therefore might not be obvious to everyone else.

It just exits the method at that point. Once return is executed, the rest of the code won't be executed.

eg.

public void test(int n) {
    if (n == 1) {
        return; 
    }
    else if (n == 2) {
        doStuff();
        return;
    }
    doOtherStuff();
}

Note that the compiler is smart enough to tell you some code cannot be reached:

if (n == 3) {
    return;
    youWillGetAnError(); //compiler error here
}

there are four types of strings available in php. They are single quotes ('), double quotes (") and Nowdoc (<<<'EOD') and heredoc(<<<EOD) strings

you can use both single quotes and double quotes inside heredoc string. Variables will be expanded just as double quotes.

nowdoc strings will not expand variables just like single quotes.

ref: http://www.php.net/manual/en/language.types.string.php#language.types.string.syntax.heredoc

Try the following:

@MvcHtmlString.Create(Model.CommentText.Replace(Environment.NewLine, "<br />"))

Update:

According to marcind's comment on this related question, the ASP.NET MVC team is looking to implement something similar to the <%: and <%= for the Razor view engine.

Update 2:

We can turn any question about HTML encoding into a discussion on harmful user inputs, but enough of that already exists.

Anyway, take care of potential harmful user input.

@MvcHtmlString.Create(Html.Encode(Model.CommentText).Replace(Environment.NewLine, "<br />"))

Update 3 (Asp.Net MVC 3):

@Html.Raw(Html.Encode(Model.CommentText).Replace("\n", "<br />"))

For the record, general_log and slow_log were introduced in 5.1.6:

http://dev.mysql.com/doc/refman/5.1/en/log-destinations.html

5.2.1. Selecting General Query and Slow Query Log Output Destinations

As of MySQL 5.1.6, MySQL Server provides flexible control over the destination of output to the general query log and the slow query log, if those logs are enabled. Possible destinations for log entries are log files or the general_log and slow_log tables in the mysql database

change layout weight according you will get....

Enter this:

 <LinearLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_gravity="center"
    android:layout_weight="0.03">
    <ImageView
        android:id="@+id/imageView"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:scaleType="centerInside"
        android:layout_gravity="center"

Visio Professional has a database reverse-engineering feature if yiu create a database diagram. It's not free but is fairly ubiquitous in most companies and should be fairly easy to get.

Note that Visio 2003 does not play nicely with SQL2005 or SQL2008 for reverse engineering - you will need to get 2007.

Here is my answer:

var str = '[me nombre es] : My name is. [Yo puedo] is the right word'; 

var reg = /\[(.*?)\]/g;

var a = str.match(reg);

a = a.toString().replace(/[\[\]]/g, "").split(','));

If you want to go the other way round (associate FILE* with existing file descriptor), use fdopen() :

                                                          FDOPEN(P)

NAME

       fdopen - associate a stream with a file descriptor

SYNOPSIS

       #include <stdio.h>

       FILE *fdopen(int fildes, const char *mode);

For those like me who struggled to get @Sunny Shah accepted answer to work on iPads. You need to set the "Requires full screen" checkbox on in the project settings. Note that this will prevent your app from working on multitasking mode which may or not be acceptable.

Use an SqlDataAdapter instead, it's much easier and you don't need to define the column names yourself, it will get the column names from the query results:

using (SqlConnection sqlcon = new SqlConnection(ConfigurationManager.ConnectionStrings["DB"].ConnectionString))
{
    using (SqlCommand cmd = new SqlCommand("usp_GetABCD", sqlcon))
    {
        cmd.CommandType = CommandType.StoredProcedure;

        using (SqlDataAdapter da = new SqlDataAdapter(cmd))
        {
            DataTable dt = new DataTable();

            da.Fill(dt);
        }
    }
}

Zoom is not included in the CSS specification, but it is supported in IE, Safari 4, Chrome (and you can get a somewhat similar effect in Firefox with -moz-transform: scale(x) since 3.5). See here.

So, all browsers

 zoom: 2;
 zoom: 200%;

will zoom your object in by 2, so it's like doubling the size. Which means if you have

a:hover {
   zoom: 2;
}

On hover, the <a> tag will zoom by 200%.

Like I say, in FireFox 3.5+ use -moz-transform: scale(x), it does much the same thing.

Edit: In response to the comment from thirtydot, I will say that scale() is not a complete replacement. It does not expand in line like zoom does, rather it will expand out of the box and over content, not forcing other content out of the way. See this in action here. Furthermore, it seems that zoom is not supported in Opera.

This post gives a useful insight into ways to work around incompatibilities with scale and workarounds for it using jQuery.

This is because you have added a library and given its dependency on a module more than once.

In my case, I had added a library as a module and as a gradle dependency both.

Removing one source of adding library (I removed gradle dependency) solved my problem.

        combo1.DisplayMember = "Text";
        combo1.ValueMember = "Value";   
        combo1.Items.Add(new { Text = "someText"), Value = "someValue") });
        dynamic item = combo1.Items[combo1.SelectedIndex];
        var itemValue = item.Value;
        var itemText = item.Text;

Unfortunatly "combo1.SelectedValue" does not work, i did not want to bind my combobox with any source, so i came up with this solution. Maybe it will help someone.

I had read yesterday that the issue was fixed for someone when that person cleared cookies. I had tried that but it did not work for me.

Checking the following section in DatabaseInterface.class.php,

        define(
            'PMA_MYSQL_INT_VERSION',
            PMA_Util::cacheGet('PMA_MYSQL_INT_VERSION', true)
        );

I figured that somehow cache is the problem. So, I remembered that I was restarting the service instead of doing a start and stop.

# restart the service
systemd restart php-fpm

# start and stop the service
systemd stop php-fpm
systemd start php-fpm

Doing a stop followed by a start fixed the issue for me.

WHERE p.[Type] = isnull(@SearchType, p.[Type])

Simple 2020 no-tricks method:

body {
    display: flex;
    flex-direction: column;
}

#footer {
    margin-top: auto;
}

I think the best solution I have come across is on this stackoverflow. This short jQuery code allows all your hover effects to show on click or touch..
No need to add anything within the function.

$('body').on('touchstart', function() {});

Hope this helps.

I found a better way to pass parameters to the popup window and even to retrieve parameters from it :

In the main page :

var popupwindow;
var sharedObject = {};

function openPopupWindow()
{
   // Define the datas you want to pass
   sharedObject.var1 = 
   sharedObject.var2 = 
   ...

   // Open the popup window
   window.open(URL_OF_POPUP_WINDOW, NAME_OF_POPUP_WINDOW, POPUP_WINDOW_STYLE_PROPERTIES);
   if (window.focus) { popupwindow.focus(); }
}

function closePopupWindow()
{
    popupwindow.close();

    // Retrieve the datas from the popup window
    = sharedObject.var1;
    = sharedObject.var2;
    ...
}

In the popup window :

var sharedObject = window.opener.sharedObject;

// function you have to to call to close the popup window
function myclose()
{
    //Define the parameters you want to pass to the main calling window
    sharedObject.var1 = 
    sharedObject.var2 = 
    ...
    window.opener.closePopupWindow();
}

That's it !

And this is very convenient because:

• You have not to set parameters in the URL of the popup window.
• No form to define
• You can use illimited parameters even objects.
• Bi-directionnal : you can pass parameters AND, if you want you, can retreive new parameters.
• Very easy to implement.

Have Fun!

Updating state every second in the react class. Note the my index.js passes a function that return current time.

import React from "react";

class App extends React.Component {
  constructor(props){
    super(props)

    this.state = {
      time: this.props.time,

    }        
  }
  updateMe() {
    setInterval(()=>{this.setState({time:this.state.time})},1000)        
  }
  render(){
  return (
    <div className="container">
      <h1>{this.state.time()}</h1>
      <button onClick={() => this.updateMe()}>Get Time</button>
    </div>
  );
}
}
export default App;

This problem is because you have used an old adb version and not support on your device. or you have more than one adb

The key is:

• make sure you have a latest adb executable on your SDK
• Make sure to run adb command from "SDK_DIR/platform-tools/" because this should be the latest version (type command "which adb" to check) if u have more than one adb file, you can rename another one.

in my case, on my Windows 7 i have one more adb on "C:\Windows\adb.exe" and its an old version, so my adb command always run from that file. I fixed the problem by running adb form my sdk directory "SDK_DIR/platform-tools/adb.exe"

For Firefox:

1. Go to LAN Settings: Options->Advanced->Network. In the "Connection" section of the "Network" tab press "Settings" button to open "Connection Settings" dialog box.
2. Select "Manual proxy configuration:" radio button
3. The "No proxy for:" textbox should contain the following text: "localhost, 127.0.0.1"

Use the error handler like this:

$('#image_id').error(function() {
  alert('Image does not exist !!');
});

If the image cannot be loaded (for example, because it is not present at the supplied URL), the alert is displayed:

Update:

I think using:

$.ajax({url:'somefile.dat',type:'HEAD',error:do_something});

would be enough to check for a 404.

More Readings:

• http://www.jibbering.com/2002/4/httprequest.html
• http://www.ibm.com/developerworks/web/library/wa-ajaxintro3/

Update 2:

Your code should be like this:

$(this).error(function() {
  alert('Image does not exist !!');
});

No need for these lines and that won't check if the remote file exists anyway:

var imgcheck = imgsrc.width;    

if (imgcheck==0) {
  alert("You have a zero size image");
} else { 
  //execute the rest of code here 
}

It looks like you want to convert the list to a list of numbers

>>> foo = ['-1.2', '0.0', '1']
>>> bar = map(float, foo)
>>> bar
[-1.2, 0.0, 1.0]
>>> min(bar)
-1.2

or if it really is strings you want, that you want to use min's key argument

>>> foo = ['-1.2', '0.0', '1']
>>> min(foo, key=float)
'-1.2'

This is the default assignment notation

for example: x ||= 1
this will check to see if x is nil or not. If x is indeed nil it will then assign it that new value (1 in our example)

more explicit:
if x == nil
x = 1
end

I am surprised that no one mentioned onmousedown instead of onclick. The

onclick='return false'

does not catch the browser's default behaviour resulting in (sometimes unwanted) text selection occurring for mousedown but

onmousedown='return false'

does.

In other words, when I click on a button, its text sometimes becomes accidentally selected changing the look of the button, that may be unwanted. That is the default behaviour that we are trying to prevent here. However, the mousedown event is registered before click, so if you only prevent that behaviour inside your click handler, it will not affect the unwanted selection arising from the mousedown event. So the text still gets selected. However, preventing default for the mousedown event will do the job.

See also event.preventDefault() vs. return false

$('.select_continent').click(function () {
    alert($(this).attr('value'));
});

Eclipse has a search feature in the top left box of the Preferences. Type in 'line numbers' in that search box, and presto...

In case you're tired of googling each time you forget...

It depends on the context.

I use if A: when I'm expecting A to be some sort of collection, and I only want to execute the block if the collection isn't empty. This allows the caller to pass any well-behaved collection, empty or not, and have it do what I expect. It also allows None and False to suppress execution of the block, which is occasionally convenient to calling code.

OTOH, if I expect A to be some completely arbitrary object but it could have been defaulted to None, then I always use if A is not None, as calling code could have deliberately passed a reference to an empty collection, empty string, or a 0-valued numeric type, or boolean False, or some class instance that happens to be false in boolean context.

And on the other other hand, if I expect A to be some more-specific thing (e.g. instance of a class I'm going to call methods of), but it could have been defaulted to None, and I consider default boolean conversion to be a property of the class I don't mind enforcing on all subclasses, then I'll just use if A: to save my fingers the terrible burden of typing an extra 12 characters.

You are looking for the cp command. You need to change directories so that you are outside of the directory you are trying to copy.

If the directory you're copying is called dir1 and you want to copy it to your /home/Pictures folder:

cp -r dir1/ ~/Pictures/

Linux is case-sensitive and also needs the / after each directory to know that it isn't a file. ~ is a special character in the terminal that automatically evaluates to the current user's home directory. If you need to know what directory you are in, use the command pwd.

When you don't know how to use a Linux command, there is a manual page that you can refer to by typing:

man [insert command here]

at a terminal prompt.

Also, to auto complete long file paths when typing in the terminal, you can hit Tab after you've started typing the path and you will either be presented with choices, or it will insert the remaining part of the path.

-- Access: 
SELECT CHR(13) & CHR(10) 

-- SQL Server: 
SELECT CHAR(13) + CHAR(10)

The error you quote has nothing to do with pg_hba.conf; it's failing to connect, not failing to authorize the connection.

Do what the error message says:

Check that the hostname and port are correct and that the postmaster is accepting TCP/IP connections

You haven't shown the command that produces the error. Assuming you're connecting on localhost port 5432 (the defaults for a standard PostgreSQL install), then either:

• PostgreSQL isn't running

• PostgreSQL isn't listening for TCP/IP connections (listen_addresses in postgresql.conf)

• PostgreSQL is only listening on IPv4 (0.0.0.0 or 127.0.0.1) and you're connecting on IPv6 (::1) or vice versa. This seems to be an issue on some older Mac OS X versions that have weird IPv6 socket behaviour, and on some older Windows versions.

• PostgreSQL is listening on a different port to the one you're connecting on

• (unlikely) there's an iptables rule blocking loopback connections

(If you are not connecting on localhost, it may also be a network firewall that's blocking TCP/IP connections, but I'm guessing you're using the defaults since you didn't say).

So ... check those:

• ps -f -u postgres should list postgres processes

• sudo lsof -n -u postgres |grep LISTEN or sudo netstat -ltnp | grep postgres should show the TCP/IP addresses and ports PostgreSQL is listening on

BTW, I think you must be on an old version. On my 9.3 install, the error is rather more detailed:

$ psql -h localhost -p 12345
psql: could not connect to server: Connection refused
        Is the server running on host "localhost" (::1) and accepting
        TCP/IP connections on port 12345?

Absolute positioning means that the element is taken completely out of the normal flow of the page layout. As far as the rest of the elements on the page are concerned, the absolutely positioned element simply doesn't exist. The element itself is then drawn separately, sort of "on top" of everything else, at the position you specify using the left, right, top and bottom attributes.

Using the position you specify with these attributes, the element is then placed at that position within its last ancestor element which has a position attribute of anything other than static (page elements default to static when no position attribute specified), or the document body (browser viewport) if no such ancestor exists.

For example, if I had this code:

<body>
  <div style="position:absolute; left: 20px; top: 20px;"></div>
</body>

...the <div> would be positioned 20px from the top of the browser viewport, and 20px from the left edge of same.

However, if I did something like this:

 <div id="outer" style="position:relative">
   <div id="inner" style="position:absolute; left: 20px; top: 20px;"></div>
 </div>

...then the inner div would be positioned 20px from the top of the outer div, and 20px from the left edge of same, because the outer div isn't positioned with position:static because we've explicitly set it to use position:relative.

Relative positioning, on the other hand, is just like stating no positioning at all, but the left, right, top and bottom attributes "nudge" the element out of their normal layout. The rest of the elements on the page still get laid out as if the element was in its normal spot though.

For example, if I had this code:

<span>Span1</span>
<span>Span2</span>
<span>Span3</span>

...then all three <span> elements would sit next to each other without overlapping.

If I set the second <span> to use relative positioning, like this:

<span>Span1</span>
<span style="position: relative; left: -5px;">Span2</span>
<span>Span3</span>

...then Span2 would overlap the right side of Span1 by 5px. Span1 and Span3 would sit in exactly the same place as they did in the first example, leaving a 5px gap between the right side of Span2 and the left side of Span3.

Hope that clarifies things a bit.

This is a simple way that works for me and uses lambda expressions:

var results = myDataTable.Select("").FirstOrDefault(x => (int)x["RowNo"] == 1)

Then if you want a particular value:

if(results != null) 
    var foo = results["ColName"].ToString()

get the latest version information from:

https://mvnrepository.com/artifact/org.apache.maven.plugins/maven-compiler-plugin

click on the latest version (or the one you'd like to use) and you'll see the the dependency info (as of 2019-05 it's 3.8.1):

<!-- https://mvnrepository.com/artifact/org.apache.maven.plugins/maven-compiler-plugin -->
<dependency>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-compiler-plugin</artifactId>
  <version>3.8.1</version>
</dependency>

you might want to use the version tag and the comment for your plugin tag.

<!-- https://mvnrepository.com/artifact/org.apache.maven.plugins/maven-compiler-plugin -->
<plugin>
    <artifactId>maven-compiler-plugin</artifactId>
    <version>3.8.1</version>
    <configuration>
        <source />
        <target />
    </configuration>
</plugin>

if you like you can modify your pom to have the version information in the properties tag as outlined in another answer.

java.net.URLEncoder.encode(finalPartOfString, "utf-8");

This will URL-encode the string.

finalPartOfString is the part after the last slash - in your case, the name of the song, as it seems.

disclaimer: this is not a just to the point answer, it's more like a piece of advice, even if the answer can be found on the references

IMHO: object oriented programming in Python sucks quite a lot.

The method dispatching is not very straightforward, you need to know about bound/unbound instance/class (and static!) methods; you can have multiple inheritance and need to deal with legacy and new style classes (yours was old style) and know how the MRO works, properties...

In brief: too complex, with lots of things happening under the hood. Let me even say, it is unpythonic, as there are many different ways to achieve the same things.

My advice: use OOP only when it's really useful. Usually this means writing classes that implement well known protocols and integrate seamlessly with the rest of the system. Do not create lots of classes just for the sake of writing object oriented code.

Take a good read to this pages:

• http://docs.python.org/reference/datamodel.html
• http://docs.python.org/tutorial/classes.html

you'll find them quite useful.

If you really want to learn OOP, I'd suggest starting with a more conventional language, like Java. It's not half as fun as Python, but it's more predictable.

Try this...

while($row = mysqli_fetch_array($result, MYSQLI_ASSOC)) {

My situation was something akin to:

switch (text) {
  case SOME_CONSTANT || ANOTHER_CONSTANT:
    console.log('Case 1 entered');

  break;

  case THIRD_CONSTANT || FINAL_CONSTANT:
    console.log('Case 2 entered');

  break;

  default:
    console.log('Default entered');
}

The default case always entered. If you're running into a similar multi-case switch statement issue, you're looking for this:

switch (text) {
  case SOME_CONSTANT:
  case ANOTHER_CONSTANT:
    console.log('Case 1 entered');

  break;

  case THIRD_CONSTANT:
  case FINAL_CONSTANT:
    console.log('Case 2 entered');

  break;

  default:
    console.log('Default entered');
}

You can use CTE also like below.

With cte as
(select Activity, SUM(Amount) as "Total Amount 2009"
   from Activities, Incomes
  where Activities.UnitName = ? AND
        Incomes.ActivityId = Activities.ActivityID
  GROUP BY Activity
),
cte1 as 
(select Activity, SUM(Amount) as "Total Amount 2008"
   from Activities, Incomes2008
  where Activities.UnitName = ? AND
        Incomes2008.ActivityId = Activities.ActivityID
  GROUP BY Activity
)
Select cte.Activity, cte.[Total Amount 2009] ,cte1.[Total Amount 2008]      
  from cte join cte1 ON cte.ActivityId = cte1.ActivityID
 WHERE a.UnitName = ?
 ORDER BY cte.Activity 

Try a list comprehension:

l = [x * 2 for x in l]

This goes through l, multiplying each element by two.

Of course, there's more than one way to do it. If you're into lambda functions and map, you can even do

l = map(lambda x: x * 2, l)

to apply the function lambda x: x * 2 to each element in l. This is equivalent to:

def timesTwo(x):
    return x * 2

l = map(timesTwo, l)

Note that map() returns a map object, not a list, so if you really need a list afterwards you can use the list() function afterwards, for instance:

l = list(map(timesTwo, l))

Thanks to Minyc510 in the comments for this clarification.

its because there is a space somewhere. I was using jsfiddle and there was a space after the tag. After I deleted the space it started working

Just write

System.Diagnostics.Process.Start(@"file path");

example

System.Diagnostics.Process.Start(@"C:\foo.jpg");
System.Diagnostics.Process.Start(@"C:\foo.doc");
System.Diagnostics.Process.Start(@"C:\foo.dxf");
...

And shell will run associated program reading it from the registry, like usual double click does.

Since not all of my clients use authenticated SMTP accounts, I resorted to using the SMTP account only if app key values are supplied in web.config file.

Here is the VB code:

sSMTPUser = ConfigurationManager.AppSettings("SMTPUser")
sSMTPPassword = ConfigurationManager.AppSettings("SMTPPassword")

If sSMTPUser.Trim.Length > 0 AndAlso sSMTPPassword.Trim.Length > 0 Then
    NetClient.Credentials = New System.Net.NetworkCredential(sSMTPUser, sSMTPPassword)

    sUsingCredentialMesg = "(Using Authenticated Account) " 'used for logging purposes
End If

NetClient.Send(Message)

Example 1 is for asp.net applications using forms authenication. This is common practice for internet applications because user is unauthenticated until it is authentcation against some security module.

Example 2 is for asp.net application using windows authenication. Windows Authentication uses Active Directory to authenticate users. The will prevent access to your application. I use this feature on intranet applications.

Use numpy.array to use shape attribute.

>>> import numpy as np
>>> X = np.array([
...     [[-9.035250067710876], [7.453250169754028], [33.34074878692627]],
...     [[-6.63700008392334], [5.132999956607819], [31.66075038909912]],
...     [[-5.1272499561309814], [8.251499891281128], [30.925999641418457]]
... ])
>>> X.shape
(3L, 3L, 1L)

NOTE X.shape returns 3-items tuple for the given array; [n, T] = X.shape raises ValueError.

• Download the svn binaries
• unpack them somewhere and add the bin folder to your PATH environment variable
• open a command line console (cmd.exe)
• enter than "svn checkout ...." command there
  • make sure to first cd to the place where you want to download (i.e checkout) the projects' code.

You should use new when you wish an object to remain in existence until you delete it. If you do not use new then the object will be destroyed when it goes out of scope. Some examples of this are:

void foo()
{
  Point p = Point(0,0);
} // p is now destroyed.

for (...)
{
  Point p = Point(0,0);
} // p is destroyed after each loop

Some people will say that the use of new decides whether your object is on the heap or the stack, but that is only true of variables declared within functions.

In the example below the location of 'p' will be where its containing object, Foo, is allocated. I prefer to call this 'in-place' allocation.

class Foo
{

  Point p;
}; // p will be automatically destroyed when foo is.

Allocating (and freeing) objects with the use of new is far more expensive than if they are allocated in-place so its use should be restricted to where necessary.

A second example of when to allocate via new is for arrays. You cannot* change the size of an in-place or stack array at run-time so where you need an array of undetermined size it must be allocated via new.

E.g.

void foo(int size)
{
   Point* pointArray = new Point[size];
   ...
   delete [] pointArray;
}

(*pre-emptive nitpicking - yes, there are extensions that allow variable sized stack allocations).

i wrote a simple ES6 class that may come handy. inspired by https://stackoverflow.com/a/58580918/4907364 answer

export class IntervalTimer {
    private callbackStartTime;
    private remaining= 0;
    private paused= false;
    public timerId = null;
    private readonly _callback;
    private readonly _delay;

    constructor(callback, delay) {
        this._callback = callback;
        this._delay = delay;
    }

    pause() {
        if (!this.paused) {
            this.clear();
            this.remaining = new Date().getTime() - this.callbackStartTime;
            this.paused = true;
        }
    }

    resume() {
        if (this.paused) {
            if (this.remaining) {
                setTimeout(() => {
                    this.run();
                    this.paused = false;
                    this.start();
                }, this.remaining);
            } else {
                this.paused = false;
                this.start();
            }
        }
    }

    clear() {
        clearInterval(this.timerId);
    }

    start() {
        this.clear();
        this.timerId = setInterval(() => {
            this.run();
        }, this._delay);
    }

    private run() {
        this.callbackStartTime = new Date().getTime();
        this._callback();
    }
}

usage is pretty straightforward,

const interval = new IntervalTimer(console.log(aaa), 3000);
interval.start();
interval.pause();
interval.resume();
interval.clear();

The below works for Normal mode: I agree with Dan Olson's answer that you should probably be in normal mode for most deletions. More details below.

If the cursor is inside the word:
diw to delete in the word (doesn't include spaces)
daw to delete around the word (includes spaces before the next word).

If the cursor is at the start of the word, just press dw.

This can be multiplied by adding the usual numbers for movement, e.g. 2w to move forward 2 words, so d2w deletes two words.

Insert Mode ^w
The idea of using hjkl for movement in Vim is that it's more productive to keep your hands on the home row. At the end of a word ^w works great to quickly delete the word. If you've gone into insert mode, entered some text and used the arrow keys to end up in the middle of the word you've gone against the home-row philosophy.
If you're in normal mode and want to change the word you can simply use the c (change) rather than d (delete) if you'd like to completely change the word, and re-enter insert mode without having to press i to get back to typing.

Go to the project's properties page, select the "Web" tab and on top (in the "Start Action" section), enter the page name in the "Specific Page" box. In your case index.aspx

My answer is similar but different, there are a few ways to achieve toggling effect. I guess it depends on your circumstance. This may not be the best way for you in the end.

The missing piece you've been looking for is to create an if statement. This allows for you to toggle your text.

More on if statements here.

JSFiddle: http://jsfiddle.net/8u2jF/

Javascript:

var status = "less";

function toggleText()
{
    var text="Here is some text that I want added to the HTML file";

    if (status == "less") {
        document.getElementById("textArea").innerHTML=text;
        document.getElementById("toggleButton").innerText = "See Less";
        status = "more";
    } else if (status == "more") {
        document.getElementById("textArea").innerHTML = "";
        document.getElementById("toggleButton").innerText = "See More";
        status = "less"
    }
}

well first of all you need to install this packege below:

sudo apt install ipython
jupyter nbconvert --to script [YOUR_NOTEBOOK].ipynb

two option is avaliable either --to python or --to=python mine was like this works fine: jupyter nbconvert --to python while.ipynb

jupyter nbconvert --to python while.ipynb 

[NbConvertApp] Converting notebook while.ipynb to python [NbConvertApp] Writing 758 bytes to while.py

pip3 install ipython

if it does not work for you try, by pip3.

pip3 install ipython

SELECT * FROM tableName WHERE columnName LIKE "%#%" OR columnName LIKE "%$%" OR (etc.)

Your form is valid. Only thing that comes to my mind is, after seeing your full html, is that you're passing your "default" value (which is not set!) instead of selecting something. Try as suggested by @Vina in the comment, i.e. giving it a selected option, or writing a default value

<select name="gender">
<option value="default">Select </option>    
<option value="male">   Male   </option>
<option value="female"> Female </option>
</select>

OR

<select name="gender">
<option value="male" selected="selected">   Male   </option>
<option value="female"> Female </option>
</select>

When you get your $_POST vars, check for them being set; you can assign a default value, or just an empty string in case they're not there.

Most important thing, AVOID SQL INJECTIONS:

//....
$fname   = isset($_POST["fname"]) ? mysql_real_escape_string($_POST['fname']) : '';
$lname   = isset($_POST['lname']) ? mysql_real_escape_string($_POST['lname']) : '';
$email   = isset($_POST['email']) ? mysql_real_escape_string($_POST['email']) : '';
you might also want to validate e-mail:
if($mail = filter_var($_POST['email'], FILTER_VALIDATE_EMAIL))
{
  $email = mysql_real_escape_string($_POST['email']);
}
else
{
  //die ('invalid email address');
  // or whatever, a default value? $email = '';
}
$paswod  = isset($_POST["paswod"]) ? mysql_real_escape_string($_POST['paswod']) : '';
$gender  = isset($_POST['gender']) ? mysql_real_escape_string($_POST['gender']) : '';

$query = mysql_query("SELECT Email FROM users WHERE Email = '".$email."')";
if(mysql_num_rows($query)> 0)
{
  echo 'userid is already there';
}
else
{
 $sql = "INSERT INTO users (FirstName, LastName, Email, Password, Gender)
         VALUES ('".$fname."','".$lname."','".$email."','".paswod."','".$gender."')";
$res = mysql_query($sql) or die('Error:'.mysql_error());
echo 'created';

You can use:

newinv=inventory+[add]

but using append is better since it doesn't create a new list:

inventory.append(add)

<?php  echo "<script>console.log({$yourVariable})</script>"; ?>

You are overwriting the start date object with the value of a DOM Element with an id of Startdate.

This should work:

var start = new Date(document.getElementById('Stardate').value);

var y = start.getFullYear();

I found that excluding the full spring-boot-starter-logging module is not necessary. All that is needed is to exclude the org.slf4j:slf4j-log4j12 module.

Adding this to a Gradle build file will resolve the issue:

configurations {
    runtime.exclude group: "org.slf4j", module: "slf4j-log4j12"
    compile.exclude group: "org.slf4j", module: "slf4j-log4j12"
}

See this other StackOverflow answer for more details.

Sure you just need to setup a local web server. Check out XAMPP: http://www.apachefriends.org/en/xampp.html

That will get you up and running in about 10 minutes.

There is now a way to run php locally without installing a server: https://stackoverflow.com/a/21872484/672229

Yes but the files need to be processed. For example you can install test servers like mamp / lamp / wamp depending on your plateform.

Basically you need apache / php running.

Use an ordered broadcast. See http://android-developers.blogspot.nl/2011/01/processing-ordered-broadcasts.html

In your activity, register a receiver in onStart, unregister in onStop. Now when for example a service needs to handle something that the activity might be able to do better, send an ordered broadcast from the service (with a default handler in the service itself). You can now respond in the activity when it is running. The service can check the result data to see if the broadcast was handled, and if not take appropriate action.

Another case that could cause this error is

>>> np.ndindex(np.random.rand(60,60))
TypeError: only integer scalar arrays can be converted to a scalar index

Using the actual shape will fix it.

>>> np.ndindex(np.random.rand(60,60).shape)
<numpy.ndindex object at 0x000001B887A98880>

try This

setTimeout( function(){ 
    // call after 5 second 
  }  , 5000 );

If you want you can achieve this using a CLR Function/Assembly.

1. Create a SQL Server CLR Assembly Project.
2. Go to properties and ensure the permission level on the Connection is setup to external
3. Add A Sql Function to the Assembly.

Here's an example which will allow you to select form your result set like a table.

public partial class UserDefinedFunctions
{
    [SqlFunction(DataAccess = DataAccessKind.Read,
        FillRowMethodName = "GetFiles_FillRow", TableDefinition = "FilePath nvarchar(4000)")]
    public static IEnumerable GetFiles(SqlString path)
    {
        return System.IO.Directory.GetFiles(path.ToString()).Select(s => new SqlString(s));
    }

    public static void GetFiles_FillRow(object obj,out SqlString filePath)
    {
        filePath = (SqlString)obj;
    }
};

And your SQL query.

use MyDb

select * From GetFiles('C:\Temp\');

Be aware though, your database needs to have CLR Assembly functionaliy enabled using the following SQL Command.

sp_configure 'clr enabled', 1
GO
RECONFIGURE
GO

CLR Assemblies (like XP_CMDShell) are disabled by default so if the reason for not using XP Cmd Shell is because you don't have permission, then you may be stuck with this option as well... just FYI.

I came across this problem today as well, though my particular issue probably isn't related to yours. After inspecting the list of files, I realized what I had done -- I had temporarily been using a file in one assembly from another assembly. I have made lots of changes to it and didn't want to orphan the SVN history, so in my branch I had moved the file over from the other assembly's folder. This isn't tracked by SVN, so it just looks like the file is deleted and then re-added. This ends up causing a tree conflict.

I resolved the problem by moving the file back, committing, and then merging my branch. Then I moved the file back afterward. :) That seemed to do the trick.

Is there some handy way of defining direction per column?

No. You cannot specify the sort order other than by a callback function that inverses the value. Not even this is possible for a multicolumn sort.

You might be able to do

 _.each(array_of_objects, function(o) {
     o.typeDesc = -o.type; // assuming a number
 });
 _.sortBy(array_of_objects, ['typeDesc', 'name'])

For everything else, you will need to resort to the native .sort() with a custom comparison function:

 array_of_objects.sort(function(a, b) {
     return a.type - b.type // asc
         || +(b.name>a.name)||-(a.name>b.name) // desc
         || …;
 });

Use the below Power shell command to change the execution timeout (Request Timeout)

Please note that I have given this for default web site, before using these please change the site and then try to use this.

 Set-WebConfigurationProperty -pspath 'MACHINE/WEBROOT/APPHOST/Default Web Site'  -filter "system.web/httpRuntime" -name "executionTimeout" -value "00:01:40"

Or, You can use the below C# code to do the same thing

using System;
using System.Text;
using Microsoft.Web.Administration;

internal static class Sample {

    private static void Main() {

        using(ServerManager serverManager = new ServerManager()) { 
            Configuration config = serverManager.GetWebConfiguration("Default Web Site");

            ConfigurationSection httpRuntimeSection = config.GetSection("system.web/httpRuntime");
            httpRuntimeSection["executionTimeout"] = TimeSpan.Parse("00:01:40");

            serverManager.CommitChanges();
        }
    }
}

Or, you can use the JavaScript to do this.

var adminManager = new ActiveXObject('Microsoft.ApplicationHost.WritableAdminManager');
adminManager.CommitPath = "MACHINE/WEBROOT/APPHOST/Default Web Site";

var httpRuntimeSection = adminManager.GetAdminSection("system.web/httpRuntime", "MACHINE/WEBROOT/APPHOST/Default Web Site");
httpRuntimeSection.Properties.Item("executionTimeout").Value = "00:01:40";

adminManager.CommitChanges();

Or, you can use the AppCmd commands.

appcmd.exe set config "Default Web Site" -section:system.web/httpRuntime /executionTimeout:"00:01:40" 

Yes. Empty or incomplete headers or response body typically caused by broken connections or server side crash can cause 502 errors if accessed via a gateway or proxy.

I was not sure about the tests in OP. I decided to experiment a little and ended up busting some of the myths.

Synchronous <script src...> will block downloading of the resources below it until it is downloaded and executed

This is no longer true. Have a look at the waterfall generated by Chrome 63:

<head>
<script src="//alias-0.redacted.com/payload.php?type=js&amp;delay=333&amp;rand=1"></script>
<script src="//alias-1.redacted.com/payload.php?type=js&amp;delay=333&amp;rand=2"></script>
<script src="//alias-2.redacted.com/payload.php?type=js&amp;delay=333&amp;rand=3"></script>
</head>

<link rel=stylesheet> will not block download and execution of scripts below it

This is incorrect. The stylesheet will not block download but it will block execution of the script (little explanation here). Have a look at performance chart generated by Chrome 63:

<link href="//alias-0.redacted.com/payload.php?type=css&amp;delay=666" rel="stylesheet">
<script src="//alias-1.redacted.com/payload.php?type=js&amp;delay=333&amp;block=1000"></script>

Keeping the above in mind, the results in OP can be explained as follows:

As a note, the SQL Server Activity Monitor for SQL Server 2008 can be found by right clicking your current server and going to "Activity Monitor" in the context menu. I found this was easiest way to kill processes if you are using the SQL Server Management Studio.

In my case I had to check the box in Overwrite the existing database (WITH REPLACE) under Options tab on Restore Database page.

The reason I was getting this error: because there was already an MDF file present for the database and it was not getting overwritten.

Hope this will help someone.

// this code works 110% tested by me after many complex jquery method validation but it is simple javascript method plz try this if u fail in drop down required validation//

Just F.Y.I I pulled my hair out with this problem for hours.. finally I call my hosting provider and found that in my case using a cloud server that in the control panel for 1and1 they have a secondary firewall that you have to clone and add port 3306. Once added I got straight in..

An answer for the future: CSS 4 will probably contain the revert keyword, which reverts a property to its value from the user or user-agent stylesheet [source]. As of writing this, only Safari supports this – check here for updates on browser support.

In your case you would use:

.my_container ol, .my_container ul {
    list-style: revert;
}

See also this other answer with some more details.

If you are uploading your files through GIT from your local machine then you can use the same command you are using in your local machine while you are connected to your live server using BASH or something like.You can use this as like you use locally.

php artisan cache:clear

php artisan route:cache

It should work.

<ul id="category-tabs">
    <li><a href="javascript:void"><i class="fa fa-plus-circle"></i>Category 1</a>
        <ul>
            <li><a href="javascript:void">item 1</a></li>
            <li><a href="javascript:void">item 2</a></li>
            <li><a href="javascript:void">item 3</a></li>
        </ul>
    </li> </ul>

//Jquery

$(document).ready(function() {
    $('li').click(function() {
      $('i').toggleClass('fa-plus-square fa-minus-square');
    });
  }); 

JSFiddle

$('input[type=file]').val()

That'll get you the file selected.

However, you can't set the value yourself.

return string.Join(", ", strings.ToArray());

In .Net 4, there's a new overload for string.Join that accepts IEnumerable<string>. The code would then look like:

return string.Join(", ", strings);

If you wanna go the modern way, you can do this:

const selectedOpts = [...field.options].filter((x) => x.selected);

The ... operator maps iterable (HTMLOptionsCollection) to the array.

If you're just interested in the values, you can add a map() call:

const selectedValues = [...field.options]
                     .filter((x) => x.selected)
                     .map((x)=>x.value);

I like to keep things as simple as possible, this works great:

#!/usr/bin/env python3
Description = """Tool description"""
Epilog  = """toolname.py -a aflag -b bflag  with these combined it does blah"""
arg_parser = argparse.ArgumentParser(
    formatter_class=argparse.RawDescriptionHelpFormatter,
    description=Description, 
    epilog=Epilog,
)
    try:
        if len(sys.argv) == 1:
            arg_parser.print_help()
    except Exception as e:
        print(e)

This is how I start all my tools as its always good to include some examples

Sometimes we need to use searching by from date & to date. If we use date__range then we need to add 1 day to to_date otherwise queryset will be empty.

Example:

from datetime import timedelta  

from_date  = parse_date(request.POST['from_date'])

to_date    = parse_date(request.POST['to_date']) + timedelta(days=1)

attendance_list = models.DailyAttendance.objects.filter(attdate__range = [from_date, to_date])

My answer is a mod of some prior answers from @JoeMills and @user.

1. Get a cURL command to log into server:

   • Load login page for website and open Network pane of Developer Tools
     • In firefox, right click page, choose 'Inspect Element (Q)' and click on Network tab
   • Go to login form, enter username, password and log in
   • After you have logged in, go back to Network pane and scroll to the top to find the POST entry. Right click and choose Copy -> Copy as CURL
   • Paste this to a text editor and try this in command prompt to see if it works
     • Its possible that some sites have hardening that will block this type of login spoofing that would require more steps below to bypass.

2. Modify cURL command to be able to save session cookie after login

   • Remove the entry -H 'Cookie: <somestuff>'
   • Add after curl at beginning -c login_cookie.txt
   • Try running this updated curl command and you should get a new file 'login_cookie.txt' in the same folder

3. Call a new web page using this new cookie that requires you to be logged in

   • curl -b login_cookie.txt <url_that_requires_log_in>

I have tried this on Ubuntu 20.04 and it works like a charm.

I think you're confusing the text and HTML methods. Look at this example, if you use an element's inner HTML as text, you'll get decoded HTML tags (second button). But if you use them as HTML, you'll get the HTML formatted view (first button).

<div id="myDiv">
    here is a <b>HTML</b> content.
</div>
<br />
<input value="Write as HTML" type="button" onclick="javascript:$('#resultDiv').html($('#myDiv').html());" />
&nbsp;&nbsp;
<input value="Write as Text" type="button" onclick="javascript:$('#resultDiv').text($('#myDiv').html());" />
<br /><br />
<div id="resultDiv">
    Results here !
</div>

First button writes : here is a HTML content.

Second button writes : here is a <B>HTML</B> content.

By the way, you can see a plug-in that I found in jQuery plugin - HTML decode and encode that encodes and decodes HTML strings.

Make sure that the field is not marked as 'not null' at the same time as you are trying to insert a default time stamp using the expression "(DATETIME('now'))"

I got the above error message while trying to access a file from Internal Storage using openFileInput("/Dir/data.txt") method with subdirectory Dir.

You cannot access sub-directories using the above method.

Try something like:

FileInputStream fIS = new FileInputStream (new File("/Dir/data.txt"));

It's better to do this through Android Studio rather than the file browser as it updates all icon files with the correct resolution for each.

To do so go to menu File ? New ? Image Asset. This will open a new dialogue and then make sure Launcher Icons is selected (Which it is by default) and then browse to the directory of your icon (it doesn't have to be in the project resources) and then once selected make sure other settings are to your liking and hit done.

Now all resolutions are saved into their respective folders, and you don't have to worry about copying it yourself or using tools, etc.

Don't forget "Shape - none" for a transparent background.

Please don't edit my answer without asking.

See:- ConnectionStrings content on this subject. There is no default command timeout property.

It may be easier. Try to think like this:

• first catch a string between regular characters
• after that find "case"

:

// 'www.dev.yyy.com'
// 'xxx.foo.pl'

var url = "xxx.foo.pl";

switch (url.match(/\..*.\./)[0]){
   case ".dev.yyy." :
          console.log("xxx.dev.yyy.com");break;

   case ".some.":
          console.log("xxx.foo.pl");break;
} //end switch

This might help you:

var element = document.getElementById("yourDivID");
element.scrollTop = element.scrollHeight;

[EDIT], to match the comment...

function updateScroll(){
    var element = document.getElementById("yourDivID");
    element.scrollTop = element.scrollHeight;
}

whenever content is added, call the function updateScroll(), or set a timer:

//once a second
setInterval(updateScroll,1000);

if you want to update ONLY if the user didn't move:

var scrolled = false;
function updateScroll(){
    if(!scrolled){
        var element = document.getElementById("yourDivID");
        element.scrollTop = element.scrollHeight;
    }
}

$("#yourDivID").on('scroll', function(){
    scrolled=true;
});

I realize you needed a solution for IE6/7 but I'm just throwing this out for anyone else.

If you can't use table-layout: fixed and you don't care about IE < 9 this works for all browsers.

td {
    overflow-x: hidden;
    overflow-y: hidden;
    white-space: nowrap;
    max-width: 30px;
}

Even if it is really discouraged to use merge cells in Excel (use Center Across Selection for instance if needed), the cell that "contains" the value is the one on the top left (at least, that's a way to express it).

Hence, you can get the value of merged cells in range B4:B11 in several ways:

• Range("B4").Value
• Range("B4:B11").Cells(1).Value
• Range("B4:B11").Cells(1,1).Value

You can also note that all the other cells have no value in them. While debugging, you can see that the value is empty.

Also note that Range("B4:B11").Value won't work (raises an execution error number 13 if you try to Debug.Print it) because it returns an array.

One thing I noticed is that Bootstrap 3 is adding the styles with both a .6s and 0.6s. So you may need to explicitly define your transition duration like this (CSS)

    .carousel-inner>.item {
    -webkit-transition: 0.9s ease-in-out left;
    transition: 0.9s ease-in-out left;
    -webkit-transition: 0.9s, ease-in-out, left;
    -moz-transition: .9s, ease-in-out, left;
    -o-transition: .9s, ease-in-out, left;
    transition: .9s, ease-in-out, left;
    }

Using this code you can take input till pressing enter of your keyboard.

char ch[100];
int i;
for (i = 0; ch[i] != '\n'; i++)
{
    scanf("%c ", &ch[i]);
}

If you really need to encode UTF-8, you can try prepending the unicode byte order mark. I have no idea how widespread the support for this method is, but ZXing at least appears to support it: http://code.google.com/p/zxing/issues/detail?id=103

I've been reading up on QR Mode recently, and I think I've seen the same practice mentioned elsewhere, but I've not the foggiest where.

use text transform property in your style tag

textTransform:'uppercase'

verse = "If you can keep your head when all about you\n Are losing theirs and blaming it on you,\nIf you can trust yourself when all men doubt you,\n But make allowance for their doubting too;\nIf you can wait and not be tired by waiting,\n Or being lied about, don’t deal in lies,\nOr being hated, don’t give way to hating,\n And yet don’t look too good, nor talk too wise:"

enter code here

print(verse)
#1. What is the length of the string variable verse?
verse_length = len(verse)
print("The length of verse is: {}".format(verse_length))
#2. What is the index of the first occurrence of the word 'and' in verse?
index = verse.find("and")
print("The index of the word 'and' in verse is {}".format(index))

It can be done using a single line:

perl -pi.back -e 's/oldString/newString/g;' inputFileName

Pay attention that oldString is processed as a Regular Expression.
In case the string contains any of {}[]()^$.|*+? (The special characters for Regular Expression syntax) make sure to escape them unless you want it to be processed as a regular expression.
Escaping it is done by \, so \[.

Create a class and put all your code in there and call an instance of this class from the Main :

static void Main(string[] args)
{

    MyClass cls  = new MyClass();
    Console.Write("Write a number: ");
    long a= Convert.ToInt64(Console.ReadLine()); // a is the number given by the user
    long av = cls.volteado(a);
    bool isTrue = cls.siprimo(a);
    ......etc

}

You could do this:

int count = test.Split('&').Length - 1;

Or with LINQ:

test.Count(x => x == '&');

Use This code to find exact X and Y cordinates :

int[] array = new int[2];
ViewForWhichLocationIsToBeFound.getLocationOnScreen(array);
if (AppConstants.DEBUG)
    Log.d(AppConstants.TAG, "array  X = " + array[0] + ", Y = " + array[1]);
ViewWhichToBeMovedOnFoundLocation.setTranslationX(array[0] + 21);
ViewWhichToBeMovedOnFoundLocation.setTranslationY(array[1] - 165);

I have added/subtracted some values to adjust my view. Please do these lines only after whole view has been inflated.

There is a handy bash utility - dos2unix - which is a DOS/MAC to UNIX text file format converter, that if not already installed on your distro, should be able to be easily installed via a package manager. dos2unix man page

You just need a way to target it, eg: <option id="myPinkOption">blah</option>

I am using the following code in one of my current projects where i download data from the internet. It is all inside my activity class.

private class GetData extends AsyncTask<String, Void, JSONObject> {

        @Override
        protected void onPreExecute() {
            super.onPreExecute();

            progressDialog = ProgressDialog.show(Calendar.this,
                    "", "");

        }

        @Override
        protected JSONObject doInBackground(String... params) {

            String response;

            try {

                HttpClient httpclient = new DefaultHttpClient();

                HttpPost httppost = new HttpPost(url);

                HttpResponse responce = httpclient.execute(httppost);

                HttpEntity httpEntity = responce.getEntity();

                response = EntityUtils.toString(httpEntity);

                Log.d("response is", response);

                return new JSONObject(response);

            } catch (Exception ex) {

                ex.printStackTrace();

            }

            return null;
        }

        @Override
        protected void onPostExecute(JSONObject result) 
        {
            super.onPostExecute(result);

            progressDialog.dismiss();

            if(result != null)
            {
                try
                {
                    JSONObject jobj = result.getJSONObject("result");

                    String status = jobj.getString("status");

                    if(status.equals("true"))
                    {
                        JSONArray array = jobj.getJSONArray("data");

                        for(int x = 0; x < array.length(); x++)
                        {
                            HashMap<String, String> map = new HashMap<String, String>();

                            map.put("name", array.getJSONObject(x).getString("name"));

                            map.put("date", array.getJSONObject(x).getString("date"));

                            map.put("description", array.getJSONObject(x).getString("description"));

                            list.add(map);
                        }

                        CalendarAdapter adapter = new CalendarAdapter(Calendar.this, list);

                        list_of_calendar.setAdapter(adapter);
                    }
                }
                catch (Exception e) 
                {
                    e.printStackTrace();
                }
            }
            else
            {
                Toast.makeText(Calendar.this, "Network Problem", Toast.LENGTH_LONG).show();
            }
        }

    }

and execute it in OnCreate Method like new GetData().execute();

where Calendar is my calendarActivity and i have also created a CalendarAdapter to set these values to a list view.

For all you non-xml config folks:

ObjectMapper objMapper = new ObjectMapper().setSerializationInclusion(JsonInclude.Include.NON_NULL);
HttpMessageConverter msgConverter = new MappingJackson2HttpMessageConverter(objMapper);
restTemplate.setMessageConverters(Collections.singletonList(msgConverter));

This also works:

    ...
    WHERE
        (FirstName IS NULL OR FirstName = ISNULL(@FirstName, FirstName)) AND
        (LastName IS NULL OR LastName = ISNULL(@LastName, LastName)) AND
        (Title IS NULL OR Title = ISNULL(@Title, Title))

You're passing the same model to the partial view as is being passed to the main view, and they are different types. The model is a DbSet of Notes, where you need to pass in a single Note.

You can do this by adding a parameter, which I'm guessing as it's the create form would be a new Note

@Html.Partial("_CreateNote", new QuickNotes.Models.Note())

You can do in this way also

var prop = $('.someProperty').closest('tr');

If the number of tr is in array

$.each(prop , function() {
  var gotTD = $(this).find('td:eq(1)');                 
});

cin >> choice;
while(choice!=99) {
    cin>>gNum;
    cin >> choice
}

You don't need a break, in that case.

There are two possible solutions for these kind of situations:

1. Use the solution suggested on this post

2. Add a unique suffix to the image src to force browser downloading it again, like this:

   var img = new Image();
   img.src = "img.jpg?_="+(new Date().getTime());
   img.onload = function () {
       alert("image is loaded");
   }
   

In this code every time adding current timestamp to the end of the image URL you make it unique and browser will download the image again

Start with a DFS: a cycle exists if and only if a back-edge is discovered during DFS. This is proved as a result of white-path theorum.

For me this was the issue. This whole block was missing from the section.

First cast your Edit text like this:

TextView tekst = (TextView) findViewById(R.id.editText1);
tekst.setText(text);

And after that close the DB not befor this line...

 myDataBaseHelper.close(); 

When leaving the current page, the CollectionView associated with the ItemsSource property of the ComboBox is purged. And because the ComboBox IsSyncronizedWithCurrent property is true by default, the SelectedItem and SelectedValue properties are reset.
This seems to be an internal data type issue in the binding. As others suggested above, if you use SelectedValue instead by binding to an int property on the viewmodel, it will work. A shortcut for you would be to override the Equals operator on MyObject so that when comparing two MyObjects, the actual Id properties are compared.

Another hint: If you do restructure your viewmodels and use SelectedValue, use it only when SelectedValuePath=Id where Id is int. If using a string key, bind to the Text property of the ComboBox instead of SelectedValue.

You should avoid setting LD_LIBRARY_PATH in your .bashrc. See "Why LD_LIBRARY_PATH is bad" for more information.

Use the linker option -rpath while linking so that the dynamic linker knows where to find libsync.so during runtime.

gcc ... -Wl,-rpath /path/to/library -L/path/to/library -lsync -o sync_test

EDIT:

Another way would be to use a wrapper like this

#!/bin/bash

LD_LIBRARY_PATH=/path/to/library sync_test "$@"

If sync_test starts any other programs, they might end up using the libs in /path/to/library which may or may not be intended.

The method you want is BigInteger#valueOf(long val).

E.g.,

BigInteger bi = BigInteger.valueOf(myInteger.intValue());

Making a String first is unnecessary and undesired.

Use JavaScript objects as associative arrays.

Associative Array: In simple words associative arrays use Strings instead of Integer numbers as index.

Create an object with

var dictionary = {};

JavaScript allows you to add properties to objects by using the following syntax:

Object.yourProperty = value;

An alternate syntax for the same is:

Object["yourProperty"] = value;

If you can, also create key-to-value object maps with the following syntax:

var point = { x:3, y:2 };

point["x"] // returns 3
point.y // returns 2

You can iterate through an associative array using the for..in loop construct as follows

for(var key in Object.keys(dict)){
  var value = dict[key];
  /* use key/value for intended purpose */
}

list.insert with any index >= len(of_the_list) places the value at the end of list. It behaves like append

Python 3.7.4
>>>lst=[10,20,30]
>>>lst.insert(len(lst), 101)
>>>lst
[10, 20, 30, 101]
>>>lst.insert(len(lst)+50, 202)
>>>lst
[10, 20, 30, 101, 202]

Time complexity, append O(1), insert O(n)

Color_Console library is comparatively easier to use. Install this library and the following code would help you.

from Color_Console import *
ctext("This will be printed" , "white" , "blue")
The first argument is the string to be printed, The second argument is the color of 
the text and the last one is the background color.

The latest version of Color_Console allows you to pass a list or dictionary of colors which would change after a specified delay time.

Also, they have good documentation on all of their functions.

Visit https://pypi.org/project/Color-Console/ to know more.

This should solve your problem: FB Share button/dialog documentation Genereally speaking you can use either normal HTML code and style it with CSS, or you can use Javascript.

Here is an example:

<a href="https://www.facebook.com/sharer/sharer.php?u=https%3A%2F%2Fparse.com" target="_blank" rel="noopener">
    <img class="YOUR_FB_CSS_STYLING_CLASS" src="img/YOUR_FB_ICON_IMAGE.png" width="22px" height="22px" alt="Share on Facebook">
</a>

Replace https%3A%2F%2Fparse.com, YOUR_FB_CSS_STYLING_CLASS and YOUR_FB_ICON_IMAGE.png with your own choices and you should be ok.

Note: For the sake of your users' security use the HTTPS link to FB, like in the a's href attribute.

You don't need the jsp:useBean to set the model if you already have a controller which prepared the model.

Just access it plain by EL:

<p>${Questions.questionPaperID}</p>
<p>${Questions.question}</p>

or by JSTL <c:out> tag if you'd like to HTML-escape the values or when you're still working on legacy Servlet 2.3 containers or older when EL wasn't supported in template text yet:

<p><c:out value="${Questions.questionPaperID}" /></p>
<p><c:out value="${Questions.question}" /></p>

See also:

• Our Servlets wiki page

Unrelated to the problem, the normal practice is by the way to start attribute name with a lowercase, like you do with normal variable names.

session.setAttribute("questions", questions);

and alter EL accordingly to use ${questions}.

Also note that you don't have any JSTL tag in your code. It's all plain JSP.

Sadly I can't answer the other questions, don't have enough reputation, but I need to point something out that was VERY important for me, and I think it will help other people too.

Unsetting the variable is a nice way, unless you need the reference of the original array!

To make clear what I mean: If you have a function wich uses the reference of the array, for example a sorting function like

function special_sort_my_array(&$array)
{
    $temporary_list = create_assoziative_special_list_out_of_array($array);

    sort_my_list($temporary_list);

    unset($array);
    foreach($temporary_list as $k => $v)
    {
        $array[$k] = $v;
    }
}

it is not working! Be careful here, unset deletes the reference, so the variable $array is created again and filled correctly, but the values are not accessable from outside the function.

So if you have references, you need to use $array = array() instead of unset, even if it is less clean and understandable.

Per google official documentation, use %1$s and %2$s http://developer.android.com/guide/topics/resources/string-resource.html#FormattingAndStyling

Update: Angular 1.1.5 added a ternary operator, so now we can simply write

<li ng-class="$first ? 'firstRow' : 'nonFirstRow'">

If you are using an earlier version of Angular, your two choices are:

1. (condition && result_if_true || !condition && result_if_false)
2. {true: 'result_if_true', false: 'result_if_false'}[condition]

item 2. above creates an object with two properties. The array syntax is used to select either the property with name true or the property with name false, and return the associated value.

E.g.,

<li class="{{{true: 'myClass1 myClass2', false: ''}[$first]}}">...</li>
 or
<li ng-class="{true: 'myClass1 myClass2', false: ''}[$first]">...</li>

$first is set to true inside an ng-repeat for the first element, so the above would apply class 'myClass1' and 'myClass2' only the first time through the loop.

With ng-class there is an easier way though: ng-class takes an expression that must evaluate to one of the following:

1. a string of space-delimited class names
2. an array of class names
3. a map/object of class names to boolean values.

An example of 1) was given above. Here is an example of 3, which I think reads much better:

 <li ng-class="{myClass: $first, anotherClass: $index == 2}">...</li>

The first time through an ng-repeat loop, class myClass is added. The 3rd time through ($index starts at 0), class anotherClass is added.

ng-style takes an expression that must evaluate to a map/object of CSS style names to CSS values. E.g.,

 <li ng-style="{true: {color: 'red'}, false: {}}[$first]">...</li>

as above, but qualitatively:

private - least access, best encapsulation
protected - some access, moderate encapsulation
public - full access, no encapsulation

the less access you provide the fewer implementation details leak out of your objects. less of this sort of leakage means more flexibility (aka "looser coupling") in terms of changing how an object is implemented without breaking clients of the object. this is a truly fundamental thing to understand.

None of the solutions worked for me. If you are using PIP do:

pip install pycrypto==2.6.1

Axios does not support canceling requests at the moment. Please see this issue for details.

UPDATE: Cancellation support was added in axios v0.15.

EDIT: The axios cancel token API is based on the withdrawn cancelable promises proposal.

Example:

const cancelTokenSource = axios.CancelToken.source();

axios.get('/user/12345', {
  cancelToken: cancelTokenSource.token
});

// Cancel request
cancelTokenSource.cancel();

Just to add to the thread as a POSSIBLE solution, I faced a similar issue when developing on a Linux system that was behind a company firewall. However, using a Windows XP machine, Eclipse was able to access different update sites just fine as both the manual and native network connection providers worked just fine using the company proxy.

After stumbling around for some time, I came across a discussion about using NTLMv2 and an implementation to be found at http://cntlm.sourceforge.net/. To whomever posted this, I give much credit to as it helped me get past the issue running on Linux. As a side note, I was using Eclipse 3.6.2 / Helios on both the Linux and Windows distros.

Best of luck on finding a solution!

Both pod and container are ephemeral, try to use the following command to stop the specific container and the k8s cluster will restart a new container.

kubectl exec -it [POD_NAME] -c [CONTAINER_NAME] -- /bin/sh -c "kill 1"

This will send a SIGTERM signal to process 1, which is the main process running in the container. All other processes will be children of process 1, and will be terminated after process 1 exits. See the kill manpage for other signals you can send.

For those have HashMap based spinner :

((HashMap)((Spinner)findViewById(R.id.YourSpinnerId)).getSelectedItem()).values().toArray()[0].toString();

If you are in a Fragment, an Adaptor or a Class other than main activities , use this:

((HashMap)((Spinner)YourInflatedLayoutOrView.findViewById(R.id.YourSpinnerId)).getSelectedItem()).values().toArray()[0].toString();

It's just for guidance; you should find your view's id before onClick method.

I would just create a separate CSS class:

.ButtonClicked {
    background-color:red;
}

And then add the class on click:

$('#ButtonId').on('click',function(){
    !$(this).hasClass('ButtonClicked') ? addClass('ButtonClicked') : '';
});

This should do what you're looking for, showing by this jsFiddle. If you're curious about the logic with the ? and such, its called ternary (or conditional) operators, and its just a concise way to do the simple if logic to check if the class has already been added.

You can also create the ability to have an "on/off" switch feel by toggling the class:

$('#ButtonId').on('click',function(){
    $(this).toggleClass('ButtonClicked');
});

Shown by this jsFiddle. Just food for thought.

When you send bytes from a buffer with a normal TCP socket, the send function returns the number of bytes of the buffer that were sent. If it is a non-blocking socket or a non-blocking send then the number of bytes sent may be less than the size of the buffer. If it is a blocking socket or blocking send, then the number returned will match the size of the buffer but the call may block. With WebSockets, the data that is passed to the send method is always either sent as a whole "message" or not at all. Also, browser WebSocket implementations do not block on the send call.

But there are more important differences on the receiving side of things. When the receiver does a recv (or read) on a TCP socket, there is no guarantee that the number of bytes returned corresponds to a single send (or write) on the sender side. It might be the same, it may be less (or zero) and it might even be more (in which case bytes from multiple send/writes are received). With WebSockets, the recipient of a message is event-driven (you generally register a message handler routine), and the data in the event is always the entire message that the other side sent.

Note that you can do message based communication using TCP sockets, but you need some extra layer/encapsulation that is adding framing/message boundary data to the messages so that the original messages can be re-assembled from the pieces. In fact, WebSockets is built on normal TCP sockets and uses frame headers that contains the size of each frame and indicate which frames are part of a message. The WebSocket API re-assembles the TCP chunks of data into frames which are assembled into messages before invoking the message event handler once per message.

I tore my app and all its dependencies to bits over this issue (details here: AngularJS app initiating twice (tried the usual solutions..))

And in the end, it was all Batarang Chrome plugin's fault.

Resolution in this answer:

I'd strongly recommend the first thing on anyone's list is to disable it per the post before altering code.

Get all distinct id, name and address columns and count the resulting rows.

SELECT COUNT(*) FROM mytable GROUP BY id, name, address

For Mac/Linux;

PYTHONPATH=/foo/bar/baz python somescript.py somecommand

For Windows, setup a wrapper pythonpath.bat;

@ECHO OFF
setlocal
set PYTHONPATH=%1
python %2 %3
endlocal

and call pythonpath.bat script file like;

pythonpath.bat /foo/bar/baz somescript.py somecommand

Or for fun:

>>> ast.literal_eval('[%s]'%','.join(map(repr,s.split())))
['QH', 'QD', 'JC', 'KD', 'JS']
>>> 

ast.literal_eval

If you don't mind using an external library, I've used Castor to do this in the past.

Scikit learn plays really well with Pandas, so I suggest you use it. Here's an example:

In [1]: 
import pandas as pd
import numpy as np
from sklearn.model_selection import train_test_split
data = np.reshape(np.random.randn(20),(10,2)) # 10 training examples
labels = np.random.randint(2, size=10) # 10 labels

In [2]: # Giving columns in X a name
X = pd.DataFrame(data, columns=['Column_1', 'Column_2'])
y = pd.Series(labels)

In [3]:
X_train, X_test, y_train, y_test = train_test_split(X, y, 
                                                    test_size=0.2, 
                                                    random_state=0)

In [4]: X_test
Out[4]:

     Column_1    Column_2
2   -1.39       -1.86
8    0.48       -0.81
4   -0.10       -1.83

In [5]: y_test
Out[5]:

2    1
8    1
4    1
dtype: int32

You can directly call any scikit functions on DataFrame/Series and it will work.

Let's say you wanted to do a LogisticRegression, here's how you could retrieve the coefficients in a nice way:

In [6]: 
from sklearn.linear_model import LogisticRegression

model = LogisticRegression()
model = model.fit(X_train, y_train)

# Retrieve coefficients: index is the feature name (['Column_1', 'Column_2'] here)
df_coefs = pd.DataFrame(model.coef_[0], index=X.columns, columns = ['Coefficient'])
df_coefs
Out[6]:
            Coefficient
Column_1    0.076987
Column_2    -0.352463

You can also just simply add the attribute row="number of rows" and cols="number of columns" like

<div class="modal-body">
    <textarea class="form-control col-xs-12" rows="7" cols="50"></textarea>
</div>

This will increase the number of rows in the textarea that is much similar to style="min-height: 100%" 100% or 80% and min-width: 50% for width etc. Also row=7 changes the height and cols=50 changes the width of textarea.

You don't have to do anything difficult!

Facebook ? Settings ? Basic:
write "localhost" in the "App Domains" field then click on "+Add Platform" choose "Web Site".

After that, in the "Site Url" field write your localhost url
(e.g.: http://localhost:1337/something).

This will allow you to test your facebook plugins locally.

Since I am in a very early stage of my data science journey, I am treating outliers with the code below.

#Outlier Treatment

def outlier_detect(df):
    for i in df.describe().columns:
        Q1=df.describe().at['25%',i]
        Q3=df.describe().at['75%',i]
        IQR=Q3 - Q1
        LTV=Q1 - 1.5 * IQR
        UTV=Q3 + 1.5 * IQR
        x=np.array(df[i])
        p=[]
        for j in x:
            if j < LTV or j>UTV:
                p.append(df[i].median())
            else:
                p.append(j)
        df[i]=p
    return df

First of all, I want to say a big screw you to React for designing an interface that doesn't let us access 'ref' on the instantiated child components, in whatever context, without having to use the 'forwardRef' "hack" (which technically only works on specific/single instances, and not dynamic collections). Thanks for making our lives harder with your proprietary hook crap and now forcing us to use functional components (which can't inherit base functionality without more hacks). Why did JavaScript add class support to begin with? Right...

With that said, here is how I solve the problem for dynamic components:

On the parent, dynamically create references to the child components, for example:

class Form extends Component {
    fieldRefs: [];

    componentWillMount = () => {
        this.fieldRefs = [];
        for(let f of this.props.children) {
            if (f && f.type.name == 'FormField') {
                f.ref = createRef();
                this.fieldRefs.push(f);
            }
        }
    }

    public getFields = () => {
        let data = {};

        for(let r of this.fieldRefs) {
            let f = r.ref.current;
            data[f.props.id] = f.field.current.value;
        }

        return data;
    }
}

The Child component (ie <FormField />) implements it's own 'field' ref, to be referred to from the parent:

class FormField extends Component {
    field = createRef();
    
    render() {
        return(
            <input ref={this.field} type={type} />
        );
    }
}

Then in your main page, "Parent Parent" component, you can get the field values from the reference with:

class Page extends Component {
    form = createRef();

    onSubmit = () => {
        let fields = this.form.current.getFields();
    }

    render() {
        return (
            <Form ref={this.form}>
                <FormField id="email" type="email" autoComplete="email" label="E-mail" />
                <FormField id="password" type="password" autoComplete="password" label="Password" />

                <div class="button" onClick={this.onSubmit}>Submit</div>
            </Form>
        );
    }
}

I implemented this because I wanted to encapsulate all generic form functionality from a main <Form /> component, and the only way to be able to have the main client/page component set and style its own inner components was to use child components (ie. <FormField /> items within the parent <Form />, which is inside some other <Page /> component).

So, while some might consider this a hack, it's just as hackey as React's attempts to block the actual 'ref' from any parent, which I think is a ridiculous design, however they want to rationalize it.

Also wtf SO. It's 2021 and we still don't have get proper code-editing tools in your editor. Ffs.

For those finding this question in dotnet core. I found a solution here

Code:

private void OpenUrl(string url)
{
    try
    {
        Process.Start(url);
    }
    catch
    {
        // hack because of this: https://github.com/dotnet/corefx/issues/10361
        if (RuntimeInformation.IsOSPlatform(OSPlatform.Windows))
        {
            url = url.Replace("&", "^&");
            Process.Start(new ProcessStartInfo("cmd", $"/c start {url}") { CreateNoWindow = true });
        }
        else if (RuntimeInformation.IsOSPlatform(OSPlatform.Linux))
        {
            Process.Start("xdg-open", url);
        }
        else if (RuntimeInformation.IsOSPlatform(OSPlatform.OSX))
        {
            Process.Start("open", url);
        }
        else
        {
            throw;
        }
    }
}

At {virtualenv}/lib/python2.7/site-packages/ (if not using virtualenv then {system_dir}/lib/python2.7/dist-packages/)

• Remove the egg file (e.g. distribute-0.6.34-py2.7.egg)
• If there is any from file easy-install.pth, remove the corresponding line (it should be a path to the source directory or of an egg file).

 ArrayList<String> sizes = new ArrayList<>();

 spinner = (Spinner) findViewById(R.id.spinner_size);

    if (sizes != null && !sizes.isEmpty()) {

        //SORT ArrayList If You Want Data in ASC or DSC Order

        sizes.add("28");
        sizes.add("29");
        sizes.add("31");

        sizes.add("Choose Size"); //adding String at the end of ArrayList
        Collections.reverse(sizes); //Last Item Will Be Shown As A Spinner Title

        ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item, sizes);
        spinner.setAdapter(adapter);

Simply use arraylist.add("Your Data") method to add item at the end of arrayList then just reverse it using Collection.reverse(arrayList) so that the Title be the 1st Item in Spinner. You can also sort the item before adding the data at the end.

You can use parseInt(jQuery.offset().top) to always use the Integer (primitive - int) value across all browsers.

James Curran's answer was the most concise in my opinion, but the output wasn't correct. For SQL Server the simplest statement is as follows:

SELECT 
    [score range] = CAST((Score/10)*10 AS VARCHAR) + ' - ' + CAST((Score/10)*10+9 AS VARCHAR), 
    [number of occurrences] = COUNT(*)
FROM #Scores
GROUP BY Score/10
ORDER BY Score/10

This assumes a #Scores temporary table I used to test it, I just populated 100 rows with random number between 0 and 99.

list_ = list(range(9)) print(list_[1::2])

Since you tagged this with strtotime, you can use it with the +1 day modifier like so:

$tomorrow_timestamp = strtotime('+1 day', strtotime('2013-01-22'));

That said, it's a much better solution to use DateTime.

Following worked for me

Enable project-specific settings and set the compliance level to 1.6

How can you do that?

In your Eclipse Package Explorer 3rd click on your project and select properties. Properties Window will open. Select Java Compiler on the left panel of the window. Now Enable project specific settings and set the Complier compliance level to 1.6. Select Apply and then OK.

1. Open 'Maven projects' (tab on the right side).
2. Use 'Add Maven Projects'
3. Find your pom.xml

Just see this page

in cmd type:

Command | clip

Then open a *.Txt file and Paste. That's it. Done.

Setting export SSL_CERT_FILE=/path/file.crt should do the job.

The fcntl module is just used for locking the pinning file, so assuming you don't try multiple access, this can be an acceptable workaround. Place this module in your sys.path, and it should just work as the official fcntl module.

Try using this module for development/testing purposes only in windows.

def fcntl(fd, op, arg=0):
    return 0

def ioctl(fd, op, arg=0, mutable_flag=True):
    if mutable_flag:
        return 0
    else:
        return ""

def flock(fd, op):
    return

def lockf(fd, operation, length=0, start=0, whence=0):
    return

You could also get this error if you are viewing accessing the page locally (via file:// instead of http://)..

There is some discussion about this here: https://github.com/jeromegn/Backbone.localStorage/issues/55

defaultdict

"The standard dictionary includes the method setdefault() for retrieving a value and establishing a default if the value does not exist. By contrast, defaultdict lets the caller specify the default(value to be returned) up front when the container is initialized."

as defined by Doug Hellmann in The Python Standard Library by Example

How to use defaultdict

Import defaultdict

>>> from collections import defaultdict

Initialize defaultdict

Initialize it by passing

callable as its first argument(mandatory)

>>> d_int = defaultdict(int)
>>> d_list = defaultdict(list)
>>> def foo():
...     return 'default value'
... 
>>> d_foo = defaultdict(foo)
>>> d_int
defaultdict(<type 'int'>, {})
>>> d_list
defaultdict(<type 'list'>, {})
>>> d_foo
defaultdict(<function foo at 0x7f34a0a69578>, {})

**kwargs as its second argument(optional)

>>> d_int = defaultdict(int, a=10, b=12, c=13)
>>> d_int
defaultdict(<type 'int'>, {'a': 10, 'c': 13, 'b': 12})

or

>>> kwargs = {'a':10,'b':12,'c':13}
>>> d_int = defaultdict(int, **kwargs)
>>> d_int
defaultdict(<type 'int'>, {'a': 10, 'c': 13, 'b': 12})

How does it works

As is a child class of standard dictionary, it can perform all the same functions.

But in case of passing an unknown key it returns the default value instead of error. For ex:

>>> d_int['a']
10
>>> d_int['d']
0
>>> d_int
defaultdict(<type 'int'>, {'a': 10, 'c': 13, 'b': 12, 'd': 0})

In case you want to change default value overwrite default_factory:

>>> d_int.default_factory = lambda: 1
>>> d_int['e']
1
>>> d_int
defaultdict(<function <lambda> at 0x7f34a0a91578>, {'a': 10, 'c': 13, 'b': 12, 'e': 1, 'd': 0})

or

>>> def foo():
...     return 2
>>> d_int.default_factory = foo
>>> d_int['f']
2
>>> d_int
defaultdict(<function foo at 0x7f34a0a0a140>, {'a': 10, 'c': 13, 'b': 12, 'e': 1, 'd': 0, 'f': 2})

Examples in the Question

Example 1

As int has been passed as default_factory, any unknown key will return 0 by default.

Now as the string is passed in the loop, it will increase the count of those alphabets in d.

>>> s = 'mississippi'
>>> d = defaultdict(int)
>>> d.default_factory
<type 'int'>
>>> for k in s:
...     d[k] += 1
>>> d.items()
[('i', 4), ('p', 2), ('s', 4), ('m', 1)]
>>> d
defaultdict(<type 'int'>, {'i': 4, 'p': 2, 's': 4, 'm': 1})

Example 2

As a list has been passed as default_factory, any unknown(non-existent) key will return [ ](ie. list) by default.

Now as the list of tuples is passed in the loop, it will append the value in the d[color]

>>> s = [('yellow', 1), ('blue', 2), ('yellow', 3), ('blue', 4), ('red', 1)]
>>> d = defaultdict(list)
>>> d.default_factory
<type 'list'>
>>> for k, v in s:
...     d[k].append(v)
>>> d.items()
[('blue', [2, 4]), ('red', [1]), ('yellow', [1, 3])]
>>> d
defaultdict(<type 'list'>, {'blue': [2, 4], 'red': [1], 'yellow': [1, 3]})

Not sure if this has changed in Laravel 5, but the accepted answer using count($data->$relation) didn't work for me, as the very act of accessing the relation property caused it to be loaded.

In the end, a straightforward isset($data->$relation) did the trick for me.

The closest thing to what you're looking for is the :first-child pseudoclass; unfortunately this will not work in your case because you have an <h1> before the <div>s. What I would suggest is that you either add a class to the <div>, like <div class="first"> and then style it that way, or use jQuery if you really can't add a class:

$('#content > div:first')

There are specific suffixes for long (e.g. 39832L), float (e.g. 2.4f) and double (e.g. -7.832d).

If there is no suffix, and it is an integral type (e.g. 5623), it is assumed to be an int. If it is not an integral type (e.g. 3.14159), it is assumed to be a double.

In all other cases (byte, short, char), you need the cast as there is no specific suffix.

The Java spec allows both upper and lower case suffixes, but the upper case version for longs is preferred, as the upper case L is less easy to confuse with a numeral 1 than the lower case l.

See the JLS section 3.10 for the gory details (see the definition of IntegerTypeSuffix).

In Javascript, there are synchronous and asynchronous functions.

Synchronous Functions

Most functions in Javascript are synchronous. If you were to call several synchronous functions in a row

doSomething();
doSomethingElse();
doSomethingUsefulThisTime();

they will execute in order. doSomethingElse will not start until doSomething has completed. doSomethingUsefulThisTime, in turn, will not start until doSomethingElse has completed.

Asynchronous Functions

Asynchronous function, however, will not wait for each other. Let us look at the same code sample we had above, this time assuming that the functions are asynchronous

doSomething();
doSomethingElse();
doSomethingUsefulThisTime();

The functions will be initialized in order, but they will all execute roughly at the same time. You can't consistently predict which one will finish first: the one that happens to take the shortest amount of time to execute will finish first.

But sometimes, you want functions that are asynchronous to execute in order, and sometimes you want functions that are synchronous to execute asynchronously. Fortunately, this is possible with callbacks and timeouts, respectively.

Callbacks

Let's assume that we have three asynchronous functions that we want to execute in order, some_3secs_function, some_5secs_function, and some_8secs_function.

Since functions can be passed as arguments in Javascript, you can pass a function as a callback to execute after the function has completed.

If we create the functions like this

function some_3secs_function(value, callback){
  //do stuff
  callback();
}

then you can call then in order, like this:

some_3secs_function(some_value, function() {
  some_5secs_function(other_value, function() {
    some_8secs_function(third_value, function() {
      //All three functions have completed, in order.
    });
  });
});

Timeouts

In Javascript, you can tell a function to execute after a certain timeout (in milliseconds). This can, in effect, make synchronous functions behave asynchronously.

If we have three synchronous functions, we can execute them asynchronously using the setTimeout function.

setTimeout(doSomething, 10);
setTimeout(doSomethingElse, 10);
setTimeout(doSomethingUsefulThisTime, 10);

This is, however, a bit ugly and violates the DRY principle^[wikipedia]. We could clean this up a bit by creating a function that accepts an array of functions and a timeout.

function executeAsynchronously(functions, timeout) {
  for(var i = 0; i < functions.length; i++) {
    setTimeout(functions[i], timeout);
  }
}

This can be called like so:

executeAsynchronously(
    [doSomething, doSomethingElse, doSomethingUsefulThisTime], 10);

In summary, if you have asynchronous functions that you want to execute syncronously, use callbacks, and if you have synchronous functions that you want to execute asynchronously, use timeouts.

and handle jquery for alert as for th e value set / Changed through div id:

$("#subscriptions input") // select the radio by its id
    .on('change', function(){ // bind a function to the change event
    alert($('input[name="subsrad"]:checked', '#subscriptions').val());
            });

it is so easy....:-}

For one thing, MVVM is a progression of the MVC pattern which uses XAML to handle the display. This article outlines some of the facets of the two.

The main thrust of the Model/View/ViewModel architecture seems to be that on top of the data (”the Model”), there’s another layer of non-visual components (”the ViewModel”) that map the concepts of the data more closely to the concepts of the view of the data (”the View”). It’s the ViewModel that the View binds to, not the Model directly.

Here is a simple answer using pandas.

import pandas as pd
list1 = ['foo', 'fob', 'faz', 'funk']
string = 'bar'

list2 = (pd.Series(list1) + string).tolist()
list2
# ['foobar', 'fobbar', 'fazbar', 'funkbar']

If you need a 3 digit number and want 001-099 to be valid numbers you should still use randrange/randint as it is quicker than alternatives. Just add the neccessary preceding zeros when converting to a string.

import random
num = random.randrange(1, 10**3)
# using format
num_with_zeros = '{:03}'.format(num)
# using string's zfill
num_with_zeros = str(num).zfill(3)

Alternatively if you don't want to save the random number as an int you can just do it as a oneliner:

'{:03}'.format(random.randrange(1, 10**3))

python 3.6+ only oneliner:

f'{random.randrange(1, 10**3):03}'

Example outputs of the above are:

• '026'
• '255'
• '512'

Implemented as a function:

import random

def n_len_rand(len_, floor=1):
    top = 10**len_
    if floor > top:
        raise ValueError(f"Floor {floor} must be less than requested top {top}")
    return f'{random.randrange(floor, top):0{len_}}'

You can create your own custom selector :hasValue and then use that to find, filter, or test any other jQuery elements.

jQuery.expr[':'].hasValue = function(el,index,match) {
  return el.value != "";
};

Then you can find elements like this:

var data = $("form input:hasValue").serialize();

Or test the current element with .is()

var elHasValue = $("#name").is(":hasValue");

jQuery.expr[':'].hasValue = function(el) {_x000D_
  return el.value != "";_x000D_
};_x000D_
_x000D_
_x000D_
var data = $("form input:hasValue").serialize();_x000D_
console.log(data)_x000D_
_x000D_
_x000D_
var elHasValue = $("[name='LastName']").is(":hasValue");_x000D_
console.log(elHasValue)

label { display: block; margin-top:10px; }

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
_x000D_
<form>_x000D_
  <label>_x000D_
    First Name:_x000D_
    <input type="text" name="FirstName" value="Frida" />_x000D_
  </label>_x000D_
_x000D_
  <label>_x000D_
    Last Name:_x000D_
    <input type="text" name="LastName" />_x000D_
  </label>_x000D_
</form>

This also works well:

:w !sudo sh -c "cat > %"

This is inspired by the comment of @Nathan Long.

NOTICE:

" must be used instead of ' because we want % to be expanded before passing to shell.

A new convolve recipe was merged into Python 3.10.

Given

import collections, operator

from itertools import chain, repeat


size = 3 + 1
kernel = [1/size] * size                                              

Code

def convolve(signal, kernel):
    # See:  https://betterexplained.com/articles/intuitive-convolution/
    # convolve(data, [0.25, 0.25, 0.25, 0.25]) --> Moving average (blur)
    # convolve(data, [1, -1]) --> 1st finite difference (1st derivative)
    # convolve(data, [1, -2, 1]) --> 2nd finite difference (2nd derivative)
    kernel = list(reversed(kernel))
    n = len(kernel)
    window = collections.deque([0] * n, maxlen=n)
    for x in chain(signal, repeat(0, n-1)):
        window.append(x)
        yield sum(map(operator.mul, kernel, window))

Demo

list(convolve(range(1, 6), kernel))
# [0.25, 0.75, 1.5, 2.5, 3.5, 3.0, 2.25, 1.25]

Details

A convolution is a general mathematical operation that can be applied to moving averages. This idea is, given some data, you slide a subset of data (window) as a "mask" or "kernel" across the data, carrying out a particular mathematical operation over each window. In the case of moving averages, the kernel is the average:

This recipe is a simple approach that is almost implemented as a Python module. In time, you can install more_itertools, a popular third-party package, to directly use this implementation.

A little late to the party, but this is how I did it for an insert:

DECLARE @ManagerID AS Varchar (25) = 'NA'
DECLARE @ManagerEmail AS Varchar (50) = 'NA'
Declare @RecordCount AS int = 0

SET @ManagerID = ?
SET @ManagerEmail = ?
SET @RecordCount = ?

INSERT INTO...

For me it was because 2 linux VMs were both mapped to the same home file system. One VM was running git-1.7.1 an the other was running git-2.14

The VM running git-1.7.1 would always show 4 files as changed (even thought the contents and line endings were identical).

Once 'git status' was run on the VM running g-2.14, then both VMs would start reporting the repository as clean. 'git status' has side effects. It is not an immutable operation. And git-1.7.1 does not understand the world in the same way that git-2+ does.

for ORA-01031: insufficient privileges. Some of the more common causes are:

1. You tried to change an Oracle username or password without having the appropriate privileges.
2. You tried to perform an UPDATE to a table, but you only have SELECT access to the table.
3. You tried to start up an Oracle database using CONNECT INTERNAL.
4. You tried to install an Oracle database without having the appropriate privileges to the operating-system.

The option(s) to resolve this Oracle error are:

1. You can have the Oracle DBA grant you the appropriate privileges that you are missing.
2. You can have the Oracle DBA execute the operation for you.
3. If you are having trouble starting up Oracle, you may need to add the Oracle user to the dba group.

For ORA-00942: table or view does not exist. You tried to execute a SQL statement that references a table or view that either does not exist, that you do not have access to, or that belongs to another schema and you didn't reference the table by the schema name.

If this error occurred because the table or view does not exist, you will need to create the table or view.

You can check to see if the table exists in Oracle by executing the following SQL statement:

select *
from all_objects
where object_type in ('TABLE','VIEW')
and object_name = 'OBJECT_NAME';

For example, if you are looking for a suppliers table, you would execute:

select *
from all_objects
where object_type in ('TABLE','VIEW')
and object_name = 'SUPPLIERS';

OPTION #2

If this error occurred because you do not have access to the table or view, you will need to have the owner of the table/view, or a DBA grant you the appropriate privileges to this object.

OPTION #3

If this error occurred because the table/view belongs to another schema and you didn't reference the table by the schema name, you will need to rewrite your SQL to include the schema name.

For example, you may have executed the following SQL statement:

select *
from suppliers;

But the suppliers table is not owned by you, but rather, it is owned by a schema called app, you could fix your SQL as follows:

select *
from app.suppliers;

If you do not know what schema the suppliers table/view belongs to, you can execute the following SQL to find out:

select owner
from all_objects
where object_type in ('TABLE','VIEW')
and object_name = 'SUPPLIERS';

This will return the schema name who owns the suppliers table.

Here it is:

success: 
    function(data) {
        $.each(data, function(i, item){
            alert("Mine is " + i + "|" + item.title + "|" + item.key);
        });
    }

Sample JSON text:

{"title": "camp crowhouse", 
"key": "agtnZW90YWdkZXYyMXIKCxIEUG9zdBgUDA"}

<?php
if(!@mysql_connect('127.0.0.1', 'root', '*your default password*'))
{
    echo "mysql not connected ".mysql_error();
    exit;

}
echo 'great work';
?>

if no error then you will get greatwork as output.

Try it saved my life XD XD

I think what you are trying to do is to wrap long text without spaces.

look at this :Hyphenator.js and it's demo.

If you are going to call relative.py directly and i.e. if you really want to import from a top level module you have to explicitly add it to the sys.path list.
Here is how it should work:

# Add this line to the beginning of relative.py file
import sys
sys.path.append('..')

# Now you can do imports from one directory top cause it is in the sys.path
import parent

# And even like this:
from parent import Parent

If you think the above can cause some kind of inconsistency you can use this instead:

sys.path.append(sys.path[0] + "/..")

sys.path[0] refers to the path that the entry point was ran from.

You could use the following to replace the first occurrence of a word within the body of the page:

var replaced = $("body").html().replace('-9o0-9909','The new string');
$("body").html(replaced);

If you wanted to replace all occurrences of a word, you need to use regex and declare it global /g:

var replaced = $("body").html().replace(/-1o9-2202/g,'The ALL new string');
$("body").html(replaced);

If you wanted a one liner:

$("body").html($("body").html().replace(/12345-6789/g,'<b>abcde-fghi</b>'));

You are basically taking all of the HTML within the <body> tags of the page into a string variable, using replace() to find and change the first occurrence of the found string with a new string. Or if you want to find and replace all occurrences of the string introduce a little regex to the mix.

See a demo here - look at the HTML top left to see the original text, the jQuery below, and the output to the bottom right.

First off, EC2 and Elastic Compute Cloud are the same thing.

Next, AWS encompasses the range of Web Services that includes EC2 and Elastic Beanstalk. It also includes many others such as S3, RDS, DynamoDB, and all the others.

EC2

EC2 is Amazon's service that allows you to create a server (AWS calls these instances) in the AWS cloud. You pay by the hour and only what you use. You can do whatever you want with this instance as well as launch n number of instances.

Elastic Beanstalk

Elastic Beanstalk is one layer of abstraction away from the EC2 layer. Elastic Beanstalk will setup an "environment" for you that can contain a number of EC2 instances, an optional database, as well as a few other AWS components such as a Elastic Load Balancer, Auto-Scaling Group, Security Group. Then Elastic Beanstalk will manage these items for you whenever you want to update your software running in AWS. Elastic Beanstalk doesn't add any cost on top of these resources that it creates for you. If you have 10 hours of EC2 usage, then all you pay is 10 compute hours.

Running Wordpress

For running Wordpress, it is whatever you are most comfortable with. You could run it straight on a single EC2 instance, you could use a solution from the AWS Marketplace, or you could use Elastic Beanstalk.

What to pick?

In the case that you want to reduce system operations and just focus on the website, then Elastic Beanstalk would be the best choice for that. Elastic Beanstalk supports a PHP stack (as well as others). You can keep your site in version control and easily deploy to your environment whenever you make changes. It will also setup an Autoscaling group which can spawn up more EC2 instances if traffic is growing.

Here's the first result off of Google when searching for "elastic beanstalk wordpress": https://www.otreva.com/blog/deploying-wordpress-amazon-web-services-aws-ec2-rds-via-elasticbeanstalk/

Using the Gnumeric spreadsheet application which comes which a commandline utility called ssconvert is indeed super simple:

Try using String.format() :

ed = (EditText) findViewById (R.id.box); 
int x = 10; 
ed.setText(String.format("%s",x)); 

"Get latest version" by default will only download the files that have changed on the server since the last time you ran "Get latest version". TFS keeps track of the files you download so it doesn't spend time downloading the same version of the files again. If you are modifying the files outside of Visual Studio, this can cause the consistency problems it sounds like you are seeing.

Based on this solution from bluefeet here is a stored procedure that uses dynamic sql to generate the transposed table. It requires that all the fields are numeric except for the transposed column (the column that will be the header in the resulting table):

You can test it with the table provided with this command:

exec SQLTranspose 'yourTable', 'color'

I read through the answers and still felt the need to stress the key point which illuminates the essence of Prepared Statements. Consider two ways to query one's database where user input is involved:

Naive Approach

One concatenates user input with some partial SQL string to generate a SQL statement. In this case the user can embed malicious SQL commands, which will then be sent to the database for execution.

String SQLString = "SELECT * FROM CUSTOMERS WHERE NAME='"+userInput+"'"

For example, malicious user input can lead to SQLString being equal to "SELECT * FROM CUSTOMERS WHERE NAME='James';DROP TABLE CUSTOMERS;'

Due to the malicious user, SQLString contains 2 statements, where the 2nd one ("DROP TABLE CUSTOMERS") will cause harm.

Prepared Statements

In this case, due to the separation of the query & data, the user input is never treated as a SQL statement, and thus is never executed. It is for this reason, that any malicious SQL code injected would cause no harm. So the "DROP TABLE CUSTOMERS" would never be executed in the case above.

In a nutshell, with prepared statements malicious code introduced via user input will not be executed!

Instead of using a submit button, try using a <button type="button">Submit</button>

You can then call a javascript function in the button, and after the alert popup is confirmed, you can manually submit the form with document.getElementById("form").submit(); ... so you'll need to name and id your form for that to work.
