you've had your sed explanation, now you can use just the shell, no need external commands

for file in F0000*
do
    echo mv "$file" "${file/#F0000/F000}"
    # ${file/#F0000/F000} means replace the pattern that starts at beginning of string
done

You can certainly do something like

However, if you find yourself using nested cursor FOR loops, it is almost always more efficient to let the database join the two results for you. After all, relational databases are really, really good at joining. I'm guessing here at what your tables look like and how they relate based on the code you posted but something along the lines of

FOR x IN (SELECT *
            FROM all_users,
                 org
           WHERE length(all_users.username) = 3
             AND all_users.username = org.username )
LOOP
  <<do something>>
END LOOP;

Go to your Target or Project settings, click the Gear icon at the bottom left, and select "Add User-Defined Setting". The new setting name should be GCC_PREPROCESSOR_DEFINITIONS, and you can type your definitions in the right-hand field.

Per Steph's comments, the full syntax is:

constant_1=VALUE constant_2=VALUE

Note that you don't need the '='s if you just want to #define a symbol, rather than giving it a value (for #ifdef statements)

I had one especific issue, i had a Single Page App and needed to show different maps, in diferent divs, one each time. I solved it in not a very beautiful way but a functionally way. Instead of hide the DOM elements with display property i used the visibility property to do it. With this approach Google Maps API had no trouble about know the dimensions of the divs where i had instantiated the maps.

I think this is what your looking for, i was looking for it my self, but then i remembered it again befor i found the code.

background-repeat: repeat-x;
background-position: top;
background-size:auto;
background-attachment: fixed;

digital evolution is on its way.

I usually do this and works always.

/try this/

for (i = res; i < *size-1; i++) { 

    arrb[i] = arrb[i + 1];
}

*size = *size - 1; /*in some ides size -- could give problems*/

Looks like you are missing the printer name, driver, and port - in that order. Your final command should resemble:

AcroRd32.exe /t <file.pdf> <printer_name> <printer_driver> <printer_port>

For example:

"C:\Program Files (x86)\Adobe\Reader 11.0\Reader\AcroRd32.exe" /t "C:\Folder\File.pdf" "Brother MFC-7820N USB Printer" "Brother MFC-7820N USB Printer" "IP_192.168.10.110"

Note: To find the printer information, right click your printer and choose properties. In my case shown above, the printer name and driver name matched - but your information may differ.

An elegant method would be to use the ~= compatible release operator according to PEP 440. In your case this would amount to:

package~=0.5.0

As an example, if the following versions exist, it would choose 0.5.9:

• 0.5.0
• 0.5.9
• 0.6.0

For clarification, each pair is equivalent:

~= 0.5.0
>= 0.5.0, == 0.5.*

~= 0.5
>= 0.5, == 0.*

You will first need to update the local formulas by doing

brew update

and then upgrade the package by doing

brew upgrade formula-name

An example would be if i wanted to upgrade mongodb, i would do something like this, assuming mongodb was already installed :

brew update && brew upgrade mongodb && brew cleanup mongodb

You can use the LocalCommand command-line option if the PermitLocalCommand option is enabled:

ssh username@hostname -o LocalCommand="tmux list-sessions"

For more details about the available options, see the ssh_config man page.

On your solution explorer window, right click to References, select Add Reference, go to .NET tab, find and add Microsoft.CSharp.

Alternatively add the Microsoft.CSharp NuGet package.

Install-Package Microsoft.CSharp

Check your DataFrame with data.columns

It should print something like this

Index([u'regiment', u'company',  u'name',u'postTestScore'], dtype='object')

Check for hidden white spaces..Then you can rename with

data = data.rename(columns={'Number ': 'Number'})

I had a similar issue reading the serial output from a digital scale. I was reading [3:12] out of a 18 characters long output string.

In my case sometimes there is a null character "\x00" (NUL) which magically appears in the scale's reply string and is not printed.

I was getting the error:

> '     0.00'
> 3 0 fast loop, delta =  10.0 weight =  0.0 
> '     0.00'
> 1 800 fast loop, delta = 10.0 weight =  0.0 
> '     0.00'
> 6 0 fast loop, delta =  10.0 weight =  0.0
> '     0\x00.0' 
> Traceback (most recent call last):
>   File "measure_weight_speed.py", line 172, in start
>     valueScale = float(answer_string) 
>     ValueError: invalid literal for float(): 0

After some research I wrote few lines of code that work in my case.

replyScale = scale_port.read(18)
answer = replyScale[3:12]
answer_decode = answer.replace("\x00", "")
answer_strip = str(answer_decode.strip())
print(repr(answer_strip))
valueScale = float(answer_strip)

The answers in these posts helped:

1. How to get rid of \x00 in my array of bytes?
2. Invalid literal for float(): 0.000001, how to fix error?

4GB's is the maximum size your iOS app can be.

As of January 26, 2017

App Size for iOS (& tvOS) only

Your app’s total uncompressed size must be less than 4GB. Each Mach-O executable file (for example, app_name.app/app_name) must not exceed these limits:

• For apps whose MinimumOSVersion is less than 7.0: maximum of 80 MB for the total of all __TEXT sections in the binary.
• For apps whose MinimumOSVersion is 7.x through 8.x: maximum of 60 MB per slice for the __TEXT section of each architecture slice in the binary.
• For apps whose MinimumOSVersion is 9.0 or greater: maximum of 500 MB for the total of all __TEXT sections in the binary.

However, consider download times when determining your app’s size. Minimize the file’s size as much as possible, keeping in mind that there is a 100 MB limit for over-the-air downloads.

This information can be found at iTunes Connect Developer Guide: Submitting the App to App Review.

In my case... with MySQL:

Declare your progress dialog:

ProgressDialog progress;

When you're ready to start the progress dialog:

progress = ProgressDialog.show(this, "dialog title",
    "dialog message", true);

and to make it go away when you're done:

progress.dismiss();

Here's a little thread example for you:

// Note: declare ProgressDialog progress as a field in your class.

progress = ProgressDialog.show(this, "dialog title",
  "dialog message", true);

new Thread(new Runnable() {
  @Override
  public void run()
  {
    // do the thing that takes a long time

    runOnUiThread(new Runnable() {
      @Override
      public void run()
      {
        progress.dismiss();
      }
    });
  }
}).start();

The use of cron on OS X is discouraged. launchd is used instead. Try man launchctl to get started. You have to create special XML files that define your jobs and put them in a special place with certain permissions.

You'll usually just need to figure out launchctl load

If you really do want to use cron on OS X, check out this answer: https://superuser.com/a/243944/2449

Because the bootstrap-select is a bootstrap component and therefore you need to include it in your code as you did for your V3

NOTE: this component only works in boostrap-4 since version 1.13.0

$('select').selectpicker();

</select>

I think the accepted way is better, but I guess this might work as well

function getElementByClass(&$parentNode, $tagName, $className, $offset = 0) {
    $response = false;

    $childNodeList = $parentNode->getElementsByTagName($tagName);
    $tagCount = 0;
    for ($i = 0; $i < $childNodeList->length; $i++) {
        $temp = $childNodeList->item($i);
        if (stripos($temp->getAttribute('class'), $className) !== false) {
            if ($tagCount == $offset) {
                $response = $temp;
                break;
            }

            $tagCount++;
        }

    }

    return $response;
}

All required parameters must be placed before any default arguments. Simply because they are mandatory, whereas default arguments are not. Syntactically, it would be impossible for the interpreter to decide which values match which arguments if mixed modes were allowed. A SyntaxError is raised if the arguments are not given in the correct order:

Let us take a look at keyword arguments, using your function.

def fun1(a="who is you", b="True", x, y):
...     print a,b,x,y

Suppose its allowed to declare function as above, Then with the above declarations, we can make the following (regular) positional or keyword argument calls:

func1("ok a", "ok b", 1)  # Is 1 assigned to x or ?
func1(1)                  # Is 1 assigned to a or ?
func1(1, 2)               # ?

How you will suggest the assignment of variables in the function call, how default arguments are going to be used along with keyword arguments.

>>> def fun1(x, y, a="who is you", b="True"):
...     print a,b,x,y
... 

Reference O'Reilly - Core-Python
Where as this function make use of the default arguments syntactically correct for above function calls. Keyword arguments calling prove useful for being able to provide for out-of-order positional arguments, but, coupled with default arguments, they can also be used to "skip over" missing arguments as well.

This is just for the record since I bumped into this post when looking for a solution to my problem which was similar to the OP's.

In my case my jQuery Ajax request was prevented from succeeding due to same-origin policy in Chrome. All was resolved when I modified my server (Node.js) to do:

response.writeHead(200,
          {
            "Content-Type": "application/json",
            "Access-Control-Allow-Origin": "http://localhost:8080"
        });

It literally cost me an hour of banging my head against the wall. I am feeling stupid...

All the references to Apache Commons are fine (and that is what most people use) but I think the Guava equivalent, Joiner, has a much nicer API.

You can do the simple join case with

Joiner.on(" and ").join(names)

but also easily deal with nulls:

Joiner.on(" and ").skipNulls().join(names);

or

Joiner.on(" and ").useForNull("[unknown]").join(names);

and (useful enough as far as I'm concerned to use it in preference to commons-lang), the ability to deal with Maps:

Map<String, Integer> ages = .....;
String foo = Joiner.on(", ").withKeyValueSeparator(" is ").join(ages);
// Outputs:
// Bill is 25, Joe is 30, Betty is 35

which is extremely useful for debugging etc.

In order for Bootstrap Beta to function properly, you must place the scripts in the following order.

<script src="js/jquery-3.2.1.min.js"></script>
  <script src="js/popper.min.js"></script>
  <script src="js/bootstrap.min.js"></script>

Here are proper instructions so that everyone can follow.

• First download Device Guard and Credential Guard hardware readiness tool from this link: https://www.microsoft.com/en-us/download/details.aspx?id=53337
• extract the zip folder content to some location like: C:\guard_tool
• you will have files like this copy file name of ps1 extension file in my case its v3.6 so it will be : DG_Readiness_Tool_v3.6.ps1

• Next click on start menu and search for powershell and then right click on it and run as Administrator.

• After that you will see blue color terminal enter command cd C:\guard_tool , replace the path after cd with your extracted location of the tool
• Now enter command: .\DG_Readiness_Tool_v3.6.ps1 -Disable
• After that reboot system
• When your system is restarting it boot time system will show notification with black background to verify that you want to disable these features so press F3 to confirm.
• do +1 if it helped :)

There's good amount of detail on logging for shell scripts via global varaibles of shell. We can emulate the similar kind of logging in shell script: http://www.cubicrace.com/2016/03/log-tracing-mechnism-for-shell-scripts.html

The post has details on introdducing log levels like INFO , DEBUG, ERROR. Tracing details like script entry, script exit, function entry, function exit.

Sample log:

Just as an FYI, you can also specify those things as column attributes. For instance, I might have done:

.order_by(model.Entry.amount.desc())

This is handy since it avoids an import, and you can use it on other places such as in a relation definition, etc.

For more information, you can refer this

Create Arraylist<Date> of Date class. And use Collections.sort() for ascending order.

See sort(List<T> list)

Sorts the specified list into ascending order, according to the natural ordering of its elements.

For Sort it in descending order See Collections.reverseOrder()

Collections.sort(yourList, Collections.reverseOrder());

Turns out it needs to be specified via escaped unicode. This question is related and contains the answer.

The solution:

h2:after {
    content: "\00a0";
}

In case the file keeps showing up even after doing everything mentioned here, make sure that this checkbox in Xcode settings is unchecked:

I had the exact same thing with two CSS files that were stored in another folder outside my main css folder. I'm using Expression Engine and found that the issue was in the rules in my htaccess file. I just added the folder to one of my conditions and it fixed it. Here's an example:

RewriteCond %{REQUEST_URI} !(images|css|js|new_folder|favicon.ico)

So it might be worth you checking your htaccess file for any potential conflicts

When having Typescript >= 2 the "lib" option in tsconfig.json will do the job. No need for Typings. https://www.typescriptlang.org/docs/handbook/compiler-options.html

I prefer using an adjacency list of Indices ( not pointers )

typedef std::vector< Vertex > Vertices;
typedef std::set <int> Neighbours;


struct Vertex {
private:
   int data;
public:
   Neighbours neighbours;

   Vertex( int d ): data(d) {}
   Vertex( ): data(-1) {}

   bool operator<( const Vertex& ref ) const {
      return ( ref.data < data );
   }
   bool operator==( const Vertex& ref ) const {
      return ( ref.data == data );
   }
};

class Graph
{
private :
   Vertices vertices;
}

void Graph::addEdgeIndices ( int index1, int index2 ) {
  vertices[ index1 ].neighbours.insert( index2 );
}


Vertices::iterator Graph::findVertexIndex( int val, bool& res )
{
   std::vector<Vertex>::iterator it;
   Vertex v(val);
   it = std::find( vertices.begin(), vertices.end(), v );
   if (it != vertices.end()){
        res = true;
       return it;
   } else {
       res = false;
       return vertices.end();
   }
}

void Graph::addEdge ( int n1, int n2 ) {

   bool foundNet1 = false, foundNet2 = false;
   Vertices::iterator vit1 = findVertexIndex( n1, foundNet1 );
   int node1Index = -1, node2Index = -1;
   if ( !foundNet1 ) {
      Vertex v1( n1 );
      vertices.push_back( v1 );
      node1Index = vertices.size() - 1;
   } else {
      node1Index = vit1 - vertices.begin();
   }
   Vertices::iterator vit2 = findVertexIndex( n2, foundNet2);
   if ( !foundNet2 ) {
      Vertex v2( n2 );
      vertices.push_back( v2 );
      node2Index = vertices.size() - 1;
   } else {
      node2Index = vit2 - vertices.begin();
   }

   assert( ( node1Index > -1 ) && ( node1Index <  vertices.size()));
   assert( ( node2Index > -1 ) && ( node2Index <  vertices.size()));

   addEdgeIndices( node1Index, node2Index );
}

Quite a few of these solutions suggest referencing the public_path() of the Laravel application in order to locate the file. Sometimes you'll want to control access to the file or offer real-time monitoring of the file. In this case, you'll want to keep the directory private and limit access by a method in a controller class. The following method should help with this:

public function show(Request $request, File $file) {

    // Perform validation/authentication/auditing logic on the request

    // Fire off any events or notifiations (if applicable)

    return response()->download(storage_path('app/' . $file->location));
}

There are other paths that you could use as well, described on Laravel's helper functions documentation

Found another possible solution for this when trying to update my Urban Airship to the latest version. In my top-level build.gradle file the code looked like:

// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.12.2'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        jcenter()
    }
}

by default as generated by Android Studio. I changed this to a later gradle version by replacing this with:

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.13.+'
    }
}

And after that the project would build.

Better one: Instead of using extra span tags in html and increasing html code, you can do as below:

<div id="sc-nav-display">
    <table class="sc-nav-table">
      <tr>
        <th class="nav-invent-head">Inventory</th>
        <th class="nav-orders-head">Orders</th>
      </tr>
    </table>
  </div> 

Here, you can use CSS as below:

#sc-nav-display th{
    font-weight: normal;
}

You just need to use ID assigned to the respected div tag of table. I used "#sc-nav-display" with "th" in CSS, so that, every other table headings will remain BOLD until and unless you do the same to all others table head as I said.

If you dont want to install dependencies and are running a *nix system you can do:

hostname -I

And you'll get all the addresses for the host, you can use that string in node:

const exec = require('child_process').exec;
let cmd = "hostname -I";
exec(cmd, function(error, stdout, stderr)
{
  console.log(stdout + error + stderr);
});

Is a one liner and you don't need other libraries like 'os' or 'node-ip' that may add accidental complexity to your code.

hostname -h

Is also your friend ;-)

Hope it helps!

A simple example: We have the following array

li = [{"id":1,"name":"ronaldo"},{"id":2,"name":"messi"}]

Now, we want to find the object in the array that has id equal to 1

1. Use method next with list comprehension

next(x for x in li if x["id"] == 1 )

2. Use list comprehension and return first item

[x for x in li if x["id"] == 1 ][0]

3. Custom Function

def find(arr , id):
    for x in arr:
        if x["id"] == id:
            return x
find(li , 1)

Output all the above methods is {'id': 1, 'name': 'ronaldo'}

you use that code

ImageView[] ivCard = new ImageView[1];

@override    
protected void onCreate(Bundle savedInstanceState)  

ivCard[0]=(ImageView)findViewById(R.id.imageView1);

You can try adding action="#{yourBean.function1}" on each button (changing of course the method function2, function3, or whatever you need). If that does not work, you can try the same with the onclick event.

Anyway, it would be easier to help you if you tell us what kind of buttons are you trying to use, a4j:commandButton or whatever you are using.

?you should do these steps :

1. the mother Element should be positioned(for EXP you can give it position:relative;)
2. the child Element should have positioned "Absolute" and values should set like this: top:0;buttom:0;right:0;left:0; (to be middle vertically)
3. for the child Element you should set "margin : auto" (to be middle vertically)
4. the child and mother Element should have "height"and"width" value
5. for mother Element => text-align:center (to be middle horizontally)

??simply here is the summery of those 5 steps:

.mother_Element {
    position : relative;
    height : 20%;
    width : 5%;
    text-align : center
    }
.child_Element {
    height : 1.2 em;
    width : 5%;
    margin : auto;
    position : absolute;
    top:0;
    bottom:0;
    left:0;
    right:0;
    }

The following works for me.

string strToday = DateTime.Today.ToString("MM/dd/yyyy");

I found a good short method that seems to work well...

Dim x, y As Integer
x = 3: y = 5  
ActiveSheet.Cells(y, x).Select
ActiveCell.Value = "Tada"

In this example we are selecting 3 columns over and 5 rows down, then putting "Tada" in the cell.

Try this

Scanner scanner = new Scanner(System.in);
int amountOfPlayers;
do {
    System.out.print("Select the amount of players (1/2): ");
    while (!scanner.hasNextInt()) {
        System.out.println("That's not a number!");
        scanner.next(); // this is important!
    }

    amountOfPlayers = scanner.nextInt();
} while ((amountOfPlayers <= 0) || (amountOfPlayers > 2));
if(scanner != null) {
    scanner.close();
}
System.out.println("You've selected " + amountOfPlayers+" player(s).");

Simple. You've two choices:

1. Check if there's ANY post data at all

//Note: This resolves as true even if all $_POST values are empty strings
if (!empty($_POST))
{
    // handle post data
    $fromPerson = '+from%3A'.$_POST['fromPerson'];
    echo $fromPerson;
}

(OR)

2. Only check if a PARTICULAR Key is available in post data

if (isset($_POST['fromPerson']) )
{
    $fromPerson = '+from%3A'.$_POST['fromPerson'];
    echo $fromPerson;
}

Just use wpdb->insert(tablename, coloumn, format) and wp will prepare that's query

<?php
global $wpdb;
$wpdb->insert("wp_submitted_form", array(
   "name" => $name,
   "email" => $email,
   "phone" => $phone,
   "country" => $country,
   "course" => $course,
   "message" => $message,
   "datesent" => $now ,
));
?>

There are really two dimensions to the scripting vs program reality:

1. Is the language powerful enough, particularly with string operations, to compete with a macro processor like the posix shell and particularly bash? If it isn't better than bash for running some function there isn't much point in using it.

2. Is the language convenient and quickly started? Java, Scala, JRuby, Closure and Groovy are all powerful languages, but Java requires a lot of boilerplate and the JVM they all require just takes too long to start up.

OTOH, Perl, Python, and Ruby all start up quickly and have powerful string handling (and pretty much everything-else-handling) operations, so they tend to occupy the sometimes-disparaged-but-not-easily-encroached-upon "scripting" world. It turns out they do well at running entire traditional programs as well.

Left in limbo are languages like Javascript, which aren't used for scripting but potentially could be. Update: since this was written node.js was released on multiple platforms. In other news, the question was closed. "Oh well."

        try { result += s.substring(0, 1).toUpperCase(); }
        catch (Throwable e) {}
        try { result += s.substring(1).toLowerCase(); }
        catch (Throwable e) {}

        return result;
    };

    return Optional.ofNullable(str)
            .map(String::trim)
            .map(capFirst)
            .orElse("");
}

I agree with the event emitting and v-model answers for those above. However, I thought I would post what I found about components with multiple form elements that want to emit back to their parent since this seems one of the first articles returned by google.

I know the question specifies a single input, but this seemed the closest match and might save people some time with similar vue components. Also, no one has mentioned the .sync modifier yet.

As far as I know, the v-model solution is only suited to one input returning to their parent. I took a bit of time looking for it but Vue (2.3.0) documentation does show how to sync multiple props sent into the component back to the parent (via emit of course).

It is appropriately called the .sync modifier.

Here is what the documentation says:

In some cases, we may need “two-way binding” for a prop. Unfortunately, true two-way binding can create maintenance issues, because child components can mutate the parent without the source of that mutation being obvious in both the parent and the child.

That’s why instead, we recommend emitting events in the pattern of update:myPropName. For example, in a hypothetical component with a title prop, we could communicate the intent of assigning a new value with:

this.$emit('update:title', newTitle)

Then the parent can listen to that event and update a local data property, if it wants to. For example:

<text-document   
 v-bind:title="doc.title"  
 v-on:update:title="doc.title = $event"
></text-document>

For convenience, we offer a shorthand for this pattern with the .sync modifier:

<text-document v-bind:title.sync="doc.title"></text-document>

You can also sync multiple at a time by sending through an object. Check out the documentation here

And i can't alter the object. I can't put new methods on it.

How do i do this?

In case you also mean how do I make the object immutable and prevent subclassing: use the final keyword

public final class Blog { //final classes can't be extended/subclassed
   private final String title; //final members have to be set in the constructor and can't be changed
   private final String author;
   private final String url;
   private final String description;
    ...
}

Edit: I just saw some of your comments and it seems you want to change the class but can't (third party I assume).

To prevent duplicates you might use a wrapper that implements appropriate equals() and hashCode(), then use the Set aproach mentioned by the others:

 class BlogWrapper {
   private Blog blog; //set via constructor etc.

   public int hashCode() {
     int hashCode = blog.getTitle().hashCode(); //check for null etc.
     //add the other hash codes as well
     return hashCode;
   }

   public boolean equals(Object other) {
     //check if both are BlogWrappers
     //remember to check for null too!
     Blog otherBlog = ((BlogWrapper)other).getBlog(); 
     if( !blog.getTitle().equals(otherBlog.getTitle()) {
       return false;
     }
     ... //check other fields as well
     return true
   }
 }

Note that this is just a rough and simple version and doesn't contain the obligatory null checks.

Finally use a Set<BlogWrapper>, loop through all the blogs and try to add new BlogWrapper(blog) to the set. In the end, you should only have unique (wrapped) blogs in the set.

Using REQUIRES_NEW is only relevant when the method is invoked from a transactional context; when the method is invoked from a non-transactional context, it will behave exactly as REQUIRED - it will create a new transaction.

That does not mean that there will only be one single transaction for all your clients - each client will start from a non-transactional context, and as soon as the the request processing will hit a @Transactional, it will create a new transaction.

So, with that in mind, if using REQUIRES_NEW makes sense for the semantics of that operation - than I wouldn't worry about performance - this would textbook premature optimization - I would rather stress correctness and data integrity and worry about performance once performance metrics have been collected, and not before.

On rollback - using REQUIRES_NEW will force the start of a new transaction, and so an exception will rollback that transaction. If there is also another transaction that was executing as well - that will or will not be rolled back depending on if the exception bubbles up the stack or is caught - your choice, based on the specifics of the operations. Also, for a more in-depth discussion on transactional strategies and rollback, I would recommend: «Transaction strategies: Understanding transaction pitfalls», Mark Richards.

I want to say that my solution was like the answer provided on this stackoverflow page: ASP.NET MVC 4, multiple models in one view?

However, in my case, the linq query they used in their Controller did not work for me.

This is said query:

var viewModels = 
        (from e in db.Engineers
         select new MyViewModel
         {
             Engineer = e,
             Elements = e.Elements,
         })
        .ToList();

Consequently, "in your view just specify that you're using a collection of view models" did not work for me either.

However, a slight variation on that solution did work for me. Here is my solution in case this helps anyone.

Here is my view model in which I know I will have just one team but that team may have multiple boards (and I have a ViewModels folder within my Models folder btw, hence the namespace):

namespace TaskBoard.Models.ViewModels
{
    public class TeamBoards
    {
        public Team Team { get; set; }
        public List<Board> Boards { get; set; }
    }
}

Now this is my controller. This is the most significant difference from the solution in the link referenced above. I build out the ViewModel to send to the view differently.

public ActionResult Details(int? id)
        {
            if (id == null)
            {
                return new HttpStatusCodeResult(HttpStatusCode.BadRequest);
            }

            TeamBoards teamBoards = new TeamBoards();
            teamBoards.Boards = (from b in db.Boards
                                 where b.TeamId == id
                                 select b).ToList();
            teamBoards.Team = (from t in db.Teams
                               where t.TeamId == id
                               select t).FirstOrDefault();

            if (teamBoards == null)
            {
                return HttpNotFound();
            }
            return View(teamBoards);
        }

Then in my view I do not specify it as a list. I just do "@model TaskBoard.Models.ViewModels.TeamBoards" Then I only need a for each when I iterate over the Team's boards. Here is my view:

@model TaskBoard.Models.ViewModels.TeamBoards

@{
    ViewBag.Title = "Details";
}

<h2>Details</h2>

<div>
    <h4>Team</h4>
    <hr />


    @Html.ActionLink("Create New Board", "Create", "Board", new { TeamId = @Model.Team.TeamId}, null)
    <dl class="dl-horizontal">
        <dt>
            @Html.DisplayNameFor(model => Model.Team.Name)
        </dt>

        <dd>
            @Html.DisplayFor(model => Model.Team.Name)
            <ul>
                @foreach(var board in Model.Boards)
                { 
                    <li>@Html.DisplayFor(model => board.BoardName)</li>
                }
            </ul>
        </dd>

    </dl>
</div>
<p>
    @Html.ActionLink("Edit", "Edit", new { id = Model.Team.TeamId }) |
    @Html.ActionLink("Back to List", "Index")
</p>

I am fairly new to ASP.NET MVC so it took me a little while to figure this out. So, I hope this post helps someone figure it out for their project in a shorter timeframe. :-)

With me the problem was solved by removing the type attribute:

<embed name="myMusic" loop="true" hidden="true" src="Music.mp3"></embed>

Cerntainly not the cleanest way.

If you're using HTML5: MP3 isn't supported by Firefox. Wav and Ogg are though. Here you can find an overview of which browser support which type of audio: http://www.w3schools.com/html/html5_audio.asp

May be not for all cases (especially if you have several NIC's), this will help:

hostname -I | awk '{ print $1 }'

If you want to print an already indented JSON:

require 'json'
...
puts JSON.pretty_generate(JSON.parse(object.to_json))

'.'.join() or ".".join().. So any string instance has the method join()

Here is simple function, tested in bash. 1st param of function is string, 2nd param is number of characters to be stripped

function stringStripNCharsFromStart { echo ${1:$2:${#1}} }

Usage:

Flow allows interface specification, without having to convert your whole code base to TypeScript.

Interfaces are a way of breaking dependencies, while stepping cautiously within existing code.

I have found the creates option in the command module useful. How about this:

- name: Move foo to bar
  command: creates="path/to/bar" mv /path/to/foo /path/to/bar

I used to do a 2 task approach using stat like Bruce P suggests. Now I do this as one task with creates. I think this is a lot clearer.

use printf with "%05d" e.g.

printf "%05d" 1

work with perl in vim:

:%!perl -pi -e s/^\s*$//g

Using sortBy... could help.

$users = User::all()->with('rated')->get()->sortByDesc('rated.rating');

Try this

test2.removeAll(test1);

Set#removeAll

Removes from this set all of its elements that are contained in the specified collection (optional operation). If the specified collection is also a set, this operation effectively modifies this set so that its value is the asymmetric set difference of the two sets.

Add comments for two different columns of the EMPLOYEE table :

Answers suggesting to disable CURLOPT_SSL_VERIFYPEER should not be accepted. The question is "Why doesn't it work with cURL", and as correctly pointed out by Martijn Hols, it is dangerous.

The error is probably caused by not having an up-to-date bundle of CA root certificates. This is typically a text file with a bunch of cryptographic signatures that curl uses to verify a host’s SSL certificate.

You need to make sure that your installation of PHP has one of these files, and that it’s up to date (otherwise download one here: http://curl.haxx.se/docs/caextract.html).

Then set in php.ini:

curl.cainfo = <absolute_path_to> cacert.pem

If you are setting it at runtime, use:

curl_setopt ($ch, CURLOPT_CAINFO, dirname(__FILE__)."/cacert.pem");

Check if you're response[0] actually exists, the error seems to suggest it doesn't.

This will remove the last comma and any whitespace after it:

str = str.replace(/,\s*$/, "");

It uses a regular expression:

• The / mark the beginning and end of the regular expression

• The , matches the comma

• The \s means whitespace characters (space, tab, etc) and the * means 0 or more

• The $ at the end signifies the end of the string

I was not able to modify the protected mode settings manually on my system since they were disabled. But the below VBA snippet for updating the registry values did the trick for me.(Please be cautious about any restrictions on your organization on modifying registry, before trying this)

Const HKEY_CURRENT_USER = &H80000001
strComputer = "."

Set ScriptMe=GetObject("winmgmts:{impersonationLevel=impersonate}!\\" & _
    strComputer & "\root\default:StdRegProv")

'Disable protected mode for local intranet'
strKeyPath = "Software\Microsoft\Windows\CurrentVersion\Internet Settings\Zones\1\"
strValueName = "2500"
dwValue = 0
ScriptMe.SetDWORDValue HKEY_CURRENT_USER,strKeyPath,strValueName,dwValue

'Disable protected mode for trusted pages'
strKeyPath = "Software\Microsoft\Windows\CurrentVersion\Internet Settings\Zones\2\"
strValueName = "2500"
dwValue = 0
ScriptMe.SetDWORDValue HKEY_CURRENT_USER,strKeyPath,strValueName,dwValue

'Disable protected mode for internet'
strKeyPath = "Software\Microsoft\Windows\CurrentVersion\Internet Settings\Zones\3\"
strValueName = "2500"
dwValue = 0
ScriptMe.SetDWORDValue HKEY_CURRENT_USER,strKeyPath,strValueName,dwValue

'Disable protected mode for restricted sites'
strKeyPath = "Software\Microsoft\Windows\CurrentVersion\Internet Settings\Zones\4\"
strValueName = "2500"
dwValue = 0
ScriptMe.SetDWORDValue HKEY_CURRENT_USER,strKeyPath,strValueName,dwValue

Just copy paste the above code into notepad and save it with .vbs extension and double click it!

Now try running your automation script again

You should use :

<img src="http://img705.imageshack.us/img705/119/original120x75.png" style="height:100px;width:100px;" alt="25"/>

That should work!!

If you want to create class then :

.size {
width:100px;
height:100px;
}

and then apply it like :

<img src="http://img705.imageshack.us/img705/119/original120x75.png" class="size" alt="25"/>

by creating a class you can use it at multiple places.

If you want to use only at one place then use inline CSS. Also Inline CSS overrides other CSS.

Just put the following code on the top of the page

@{
    Layout = "";
}

I would never recommend SendGrid. I took up their free account offer and never managed to send a single email - all got blocked - I spent days trying to resolve it. When I enquired why they got blocked, they told me that free accounts share an ip address and if any account abuses that ip by sending spam - then everyone on the shared ip address gets blocked - totally useless. Also if you use them - do not store your email key in a git public repository as anyone can read the key from there (using a crawler) and use your chargeable account to send bulk emails.

A free email service which I've been using reliably with an Azure website is to use my Gmail (Google mail) account. That account has an option for using it with applications - once you enable that, then email can be sent from your azure website. Pasting in sample send code as the port to use (587) is not obvious.

  public static void SendMail(MailMessage Message)
    {
        SmtpClient client = new SmtpClient();
        client.Host = EnvironmentSecret.Instance.SmtpHost; // smtp.googlemail.com
        client.Port = 587;
        client.UseDefaultCredentials = false;
        client.DeliveryMethod = SmtpDeliveryMethod.Network;
        client.EnableSsl = true;
        client.Credentials = new NetworkCredential(
            EnvironmentSecret.Instance.NetworkCredentialUserName,
            EnvironmentSecret.Instance.NetworkCredentialPassword);
        client.Send(Message);
    }

You should try using isinstance()

if isinstance(object, list):
       ## DO what you want

In your case

if isinstance(tmpDict[key], list):
      ## DO SOMETHING

To elaborate:

x = [1,2,3]
if type(x) == list():
    print "This wont work"
if type(x) == list:                  ## one of the way to see if it's list
    print "this will work"           
if type(x) == type(list()):
    print "lets see if this works"
if isinstance(x, list):              ## most preferred way to check if it's list
    print "This should work just fine"

The difference between isinstance() and type() though both seems to do the same job is that isinstance() checks for subclasses in addition, while type() doesn’t.

Since Qt 5.8, we now have QDateTime::currentSecsSinceEpoch() to deliver the seconds directly, a.k.a. as real Unix timestamp. So, no need to divide the result by 1000 to get seconds anymore.

Credits: also posted as comment to this answer. However, I think it is easier to find if it is a separate answer.

You have to read the data too.

Check out : http://www.doughellmann.com/PyMOTW/urllib2/ to understand it.

response = urllib2.urlopen(..)
headers = response.info()
data = response.read()

Of course, what you want is to render it in browser and aaronasterling's answer is what you want.

Implement LocalizedError:

struct StringError : LocalizedError
{
    var errorDescription: String? { return mMsg }
    var failureReason: String? { return mMsg }
    var recoverySuggestion: String? { return "" }
    var helpAnchor: String? { return "" }

    private var mMsg : String

    init(_ description: String)
    {
        mMsg = description
    }
}

Note that simply implementing Error, for instance, as described in one of the answers, will fail (at least in Swift 3), and calling localizedDescription will result in the string "The operation could not be completed. (.StringError error 1.)"

Incase arguments have spaces in it, you can pass like shown below.

java -jar myjar.jar 'first argument' 'second argument'

Please see https://angular.io/guide/pipes#appendix-no-filterpipe-or-orderbypipe for the full discussion. This quote is most relevant. Basically, for large scale apps that should be minified aggressively the filtering and sorting logic should move to the component itself.

"Some of us may not care to minify this aggressively. That's our choice. But the Angular product should not prevent someone else from minifying aggressively. Therefore, the Angular team decided that everything shipped in Angular will minify safely.

The Angular team and many experienced Angular developers strongly recommend that you move filtering and sorting logic into the component itself. The component can expose a filteredHeroes or sortedHeroes property and take control over when and how often to execute the supporting logic. Any capabilities that you would have put in a pipe and shared across the app can be written in a filtering/sorting service and injected into the component."

Because your question is phrased regarding your error message and not whatever your function is trying to accomplish, I will address the error.

- is the 'binary operator' your error is referencing, and either CurrentDay or MA (or both) are non-numeric.

A binary operation is a calculation that takes two values (operands) and produces another value (see wikipedia for more). + is one such operator: "1 + 1" takes two operands (1 and 1) and produces another value (2). Note that the produced value isn't necessarily different from the operands (e.g., 1 + 0 = 1).

R only knows how to apply + (and other binary operators, such as -) to numeric arguments:

> 1 + 1
[1] 2
> 1 + 'one'
Error in 1 + "one" : non-numeric argument to binary operator

When you see that error message, it means that you are (or the function you're calling is) trying to perform a binary operation with something that isn't a number.

EDIT:

Your error lies in the use of [ instead of [[. Because Day is a list, subsetting with [ will return a list, not a numeric vector. [[, however, returns an object of the class of the item contained in the list:

> Day <- Transaction(1, 2)["b"]
> class(Day)
[1] "list"
> Day + 1
Error in Day + 1 : non-numeric argument to binary operator

> Day2 <- Transaction(1, 2)[["b"]]
> class(Day2)
[1] "numeric"
> Day2 + 1
[1] 3

Transaction, as you've defined it, returns a list of two vectors. Above, Day is a list contain one vector. Day2, however, is simply a vector.

What's wrong with using 'key_name' instead, even if it is a variable?

Brief answer to your question: No. You shouldn't call ConfigureAwait(false) at the application level like that.

TL;DR version of the long answer: If you are writing a library where you don't know your consumer and don't need a synchronization context (which you shouldn't in a library I believe), you should always use ConfigureAwait(false). Otherwise, the consumers of your library may face deadlocks by consuming your asynchronous methods in a blocking fashion. This depends on the situation.

Here is a bit more detailed explanation on the importance of ConfigureAwait method (a quote from my blog post):

When you are awaiting on a method with await keyword, compiler generates bunch of code in behalf of you. One of the purposes of this action is to handle synchronization with the UI (or main) thread. The key component of this feature is the SynchronizationContext.Current which gets the synchronization context for the current thread. SynchronizationContext.Current is populated depending on the environment you are in. The GetAwaiter method of Task looks up for SynchronizationContext.Current. If current synchronization context is not null, the continuation that gets passed to that awaiter will get posted back to that synchronization context.

When consuming a method, which uses the new asynchronous language features, in a blocking fashion, you will end up with a deadlock if you have an available SynchronizationContext. When you are consuming such methods in a blocking fashion (waiting on the Task with Wait method or taking the result directly from the Result property of the Task), you will block the main thread at the same time. When eventually the Task completes inside that method in the threadpool, it is going to invoke the continuation to post back to the main thread because SynchronizationContext.Current is available and captured. But there is a problem here: the UI thread is blocked and you have a deadlock!

Also, here are two great articles for you which are exactly for your question:

• The Perfect Recipe to Shoot Yourself in The Foot - Ending up with a Deadlock Using the C# 5.0 Asynchronous Language Features
• Asynchronous .NET Client Libraries for Your HTTP API and Awareness of async/await's Bad Effects

Finally, there is a great short video from Lucian Wischik exactly on this topic: Async library methods should consider using Task.ConfigureAwait(false).

Hope this helps.

What I usually do is create a delete page that shows a confirmation form if the request method is "GET" and deletes the data if the method was "POST" and the user chose the "Yes" option.

Then, in the page with the delete link, I add an onclick function (or just use the jQuery confirm plugin) that uses AJAX to post to the link, bypassing the confirmation page.

Here's the idea in pseudo code:

delete.php:

<?php
if ($_SERVER['REQUEST_METHOD'] == 'POST') {
    if ($_POST['confirm'] == 'Yes') {
        delete_record($_REQUEST['id']); // From GET or POST variables
    }
    redirect($_POST['referer']);
}
?>

<form action="delete.php" method="post">
    Are you sure?
    <input type="submit" name="confirm" value="Yes">
    <input type="submit" name="confirm" value="No">

    <input type="hidden" name="id" value="<?php echo $_GET['id']; ?>">
    <input type="hidden" name="referer" value="<?php echo $_SERVER['HTTP_REFERER']; ?>">
</form>

Page with delete link:

<script>
    function confirmDelete(link) {
        if (confirm("Are you sure?")) {
            doAjax(link.href, "POST"); // doAjax needs to send the "confirm" field
        }
        return false;
    }
</script>

<a href="delete.php?id=1234" onclick="return confirmDelete(this);">Delete record</a>

If you have Git bash installed, you can do something like this:

/c/Program\ Files\ \(x86\)/PostgreSQL/9.3/bin/psql -U <pg_role_name> -d <pg_database_name> < <path_to_your>.sql

In my case it was the use of the call_command module that posed a problem.
I added set DJANGO_SETTINGS_MODULE=mysite.settings but it didn't work.

I finally found it:

add these lines at the top of the script, and the order matters.

import os
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "mysite.settings")

import django
django.setup()

from django.core.management import call_command

If you want to launch VM by sending arguments, you should send VM arguments and not Program arguments.

Program arguments are arguments that are passed to your application, which are accessible via the "args" String array parameter of your main method. VM arguments are arguments such as System properties that are passed to the JavaSW interpreter. The Debug configuration above is essentially equivalent to:

java -DsysProp1=sp1 -DsysProp2=sp2 test.ArgsTest pro1 pro2 pro3

The VM arguments go after the call to your Java interpreter (ie, 'java') and before the Java class. Program arguments go after your Java class.

Consider a program ArgsTest.java:

package test;

import java.io.IOException;

    public class ArgsTest {

        public static void main(String[] args) throws IOException {

            System.out.println("Program Arguments:");
            for (String arg : args) {
                System.out.println("\t" + arg);
            }

            System.out.println("System Properties from VM Arguments");
            String sysProp1 = "sysProp1";
            System.out.println("\tName:" + sysProp1 + ", Value:" + System.getProperty(sysProp1));
            String sysProp2 = "sysProp2";
            System.out.println("\tName:" + sysProp2 + ", Value:" + System.getProperty(sysProp2));

        }
    }

If given input as,

java -DsysProp1=sp1 -DsysProp2=sp2 test.ArgsTest pro1 pro2 pro3 

in the commandline, in project bin folder would give the following result:

Program Arguments:
  pro1
  pro2
  pro3
System Properties from VM Arguments
  Name:sysProp1, Value:sp1
  Name:sysProp2, Value:sp2

Here's a recent css-tricks article which discusses this.

Some of the solutions in the above article (which are not mentioned here) are

1) -webkit-line-clamp and 2) Place an absolutely positioned element to the bottom right with fade out

Both methods assume the following markup:

<div class="module"> /* Add line-clamp/fade class here*/
  <p>Text here</p>
</div>

with css

.module {
  width: 250px;
  overflow: hidden;
}

1) -webkit-line-clamp

line-clamp FIDDLE (..for a maximum of 3 lines)

.line-clamp {
  display: -webkit-box;
  -webkit-line-clamp: 3;
  -webkit-box-orient: vertical;  
  max-height: 3.6em; /* I needed this to get it to work */
}

2) fade out

Let's say you set the line-height to 1.2em. If we want to expose three lines of text, we can just make the height of the container 3.6em (1.2em × 3). The hidden overflow will hide the rest.

Fade out FIDDLE

p
{
    margin:0;padding:0;
}
.module {
  width: 250px;
  overflow: hidden;
  border: 1px solid green;
  margin: 10px;
}

.fade {
  position: relative;
  height: 3.6em; /* exactly three lines */
}
.fade:after {
  content: "";
  text-align: right;
  position: absolute;
  bottom: 0;
  right: 0;
  width: 70%;
  height: 1.2em;
  background: linear-gradient(to right, rgba(255, 255, 255, 0), rgba(255, 255, 255, 1) 50%);
}

Solution #3 - A combination using @supports

We can use @supports to apply webkit's line-clamp on webkit browsers and apply fade out in other browsers.

@supports line-clamp with fade fallback fiddle

<div class="module line-clamp">
  <p>Pellentesque habitant morbi tristique senectus et netus et malesuada fames ac turpis egestas. Vestibulum tortor quam, feugiat vitae, ultricies eget, tempor sit amet, ante. Donec eu libero sit amet quam egestas semper. Aenean ultricies mi vitae est. Mauris placerat eleifend leo.</p>
</div>

CSS

.module {
  width: 250px;
  overflow: hidden;
  border: 1px solid green;
  margin: 10px;
}

.line-clamp {
      position: relative;
      height: 3.6em; /* exactly three lines */
    }
.line-clamp:after {
      content: "";
      text-align: right;
      position: absolute;
      bottom: 0;
      right: 0;
      width: 70%;
      height: 1.2em;
      background: linear-gradient(to right, rgba(255, 255, 255, 0), rgba(255, 255, 255, 1) 50%);
 }

@supports (-webkit-line-clamp: 3) {
    .line-clamp {
        display: -webkit-box;
        -webkit-line-clamp: 3;
        -webkit-box-orient: vertical;  
        max-height:3.6em; /* I needed this to get it to work */
        height: auto;
    }
    .line-clamp:after {
        display: none;
    }
}

Though previous posters covered your particular error, you can get 'Undefined reference' linker errors when attempting to compile C code with g++, if you don't tell the compiler to use C linkage.

For example you should do this in your C header files:

extern "C" {

...

void myfunc(int param);

...

}

To make 'myfunc' available in C++ programs.

If you still also want to use this from C, wrap the extern "C" { and } in #ifdef __cplusplus preprocessor conditionals, like

#ifdef __cplusplus
extern "C" {
#endif

This way, the extern block will just be “skipped” when using a C compiler.

If you just want to display it when you get a response add this to your loadpage()

function loadpage(page_request, containerid){
   if (page_request.readyState == 4 && page_request.status==200) { 
      var container = document.getElementById(containerid);
      container.innerHTML=page_request.responseText;
      container.style.visibility = 'visible';
      // or 
      container.style.display = 'block';
}

but this depend entirely on how you hid the div in the first place

I would like to show a little example on how is and == are involved in immutable types. Try that:

a = 19998989890
b = 19998989889 +1
>>> a is b
False
>>> a == b
True

is compares two objects in memory, == compares their values. For example, you can see that small integers are cached by Python:

c = 1
b = 1
>>> b is c
True

You should use == when comparing values and is when comparing identities. (Also, from an English point of view, "equals" is different from "is".)

function xxxx() {
// submit or validate here , disable after that using below
  document.getElementById('buttonId').disabled = 'disabled';
  document.getElementById('buttonId').disabled = '';
}

I slightly modified khel version for one reason: Every regexp parse/replace will cost O(n) operations, where n is number of characters in target text. But, regexp is not exactly what we need. So:

Here's a short Python program I wrote to complete this task. It was written in a couple of minutes, so it can probably be made better. Not sure how it'll handle nested tables (probably it'll do bad stuff) or multiple tables (probably they'll just appear one after another). It doesn't handle colspan or rowspan. Enjoy.

from HTMLParser import HTMLParser
import sys
import re


class HTMLTableParser(HTMLParser):
    def __init__(self, row_delim="\n", cell_delim="\t"):
        HTMLParser.__init__(self)
        self.despace_re = re.compile(r'\s+')
        self.data_interrupt = False
        self.first_row = True
        self.first_cell = True
        self.in_cell = False
        self.row_delim = row_delim
        self.cell_delim = cell_delim

    def handle_starttag(self, tag, attrs):
        self.data_interrupt = True
        if tag == "table":
            self.first_row = True
            self.first_cell = True
        elif tag == "tr":
            if not self.first_row:

I know this is quite an old question, but with Java 8's Streams you can get a range of ints like this:

// gives an IntStream of integers from 0 through Integer.MAX_VALUE
IntStream.rangeClosed(0, Integer.MAX_VALUE); 

Then you can do something like this:

if (IntStream.rangeClosed(0, Integer.MAX_VALUE).matchAny(n -> n == A)) {
    // do something
} else {
    // do something else 
}

I just tried and it works with require "./tokenizer". Hope this helps.

You have to play with JSFiddle loading option :

set it to "No wrap - in body" instead of "onload"

Working fiddle : http://jsfiddle.net/zQv9n/1/

In addition to DCookie's answer above, you can also use chr(39) for a single quote.

I find this particularly useful when I have to create a number of insert/update statements based on a large amount of existing data.

Here's a very quick example:

Lets say we have a very simple table, Customers, that has 2 columns, FirstName and LastName. We need to move the data into Customers2, so we need to generate a bunch of INSERT statements.

Select 'INSERT INTO Customers2 (FirstName, LastName) ' ||
       'VALUES (' || chr(39) || FirstName || chr(39) ',' || 
       chr(39) || LastName || chr(39) || ');' From Customers;

I've found this to be very useful when moving data from one environment to another, or when rebuilding an environment quickly.

It gets interesting when you find out that NONE of ALL THE ANSWERS in this thread were helpful.

And then you find out that in your version of ADT 22.6.3.v201404151837-1123206 if you add two filters with the same package name(application name) then the log will not appear.

It was weird because the log was there two seconds ago, and launching the app in debug mode adds a default filter for the app which collides with the filter I've setup manually, and then ADT magically removes all the log, and NONE of the filter worked including the All messages(no filters)!

I hope I saved someone some time... I was at it for almost an hour.

==== UPDATE ====

And then I spent another short while figuring that this was masking another issue...

I'm working with dual screens, the second one is connected via VGA/RGB - (not really sure how its called) and what can I do, I'm a ton more comfortable with the logcat away from my code editors, so I've placed it in another window, and as it turns out that is the main reason for the disappearing logs for me.

Here is the example:

SQL> set define off;
SQL> select * from dual where dummy='&var';

no rows selected

SQL> set define on
SQL> /
Enter value for var: X
old   1: select * from dual where dummy='&var'
new   1: select * from dual where dummy='X'

D
-
X

With set define off, it took a row with &var value, prompted a user to enter a value for it and replaced &var with the entered value (in this case, X).

It can be done using the border-radius property. basically, you need to set the border-radius to exactly half of the height and width to get a circle.

JSFiddle

If you need old XLS format. Below code for ansii 'cp1251'.

import xlrd

file=u'C:/Landau/task/6200.xlsx'

try:
    book = xlrd.open_workbook(file,encoding_override="cp1251")  
except:
    book = xlrd.open_workbook(file)
print("The number of worksheets is {0}".format(book.nsheets))
print("Worksheet name(s): {0}".format(book.sheet_names()))
sh = book.sheet_by_index(0)
print("{0} {1} {2}".format(sh.name, sh.nrows, sh.ncols))
print("Cell D30 is {0}".format(sh.cell_value(rowx=29, colx=3)))
for rx in range(sh.nrows):
   print(sh.row(rx))

Adding margin to align images:

Since we wanted the image to be left-aligned, we added:

img {
  margin-right: auto;
}

Similarly for image to be right-aligned, we can add margin-right: auto;. The snippet shows a demo for both types of alignment.

Good Luck...

man 1 nm

For example:

nm -gU /usr/local/Cellar/cairo/1.12.16/lib/cairo/libcairo-trace.0.dylib

The order in which you use middleware in Express matters: middleware declared earlier will get called first, and if it can handle a request, any middleware declared later will not get called.

If express.static is handling the request, you need to move your middleware up:

// need cookieParser middleware before we can do anything with cookies
app.use(express.cookieParser());

// set a cookie
app.use(function (req, res, next) {
  // check if client sent cookie
  var cookie = req.cookies.cookieName;
  if (cookie === undefined) {
    // no: set a new cookie
    var randomNumber=Math.random().toString();
    randomNumber=randomNumber.substring(2,randomNumber.length);
    res.cookie('cookieName',randomNumber, { maxAge: 900000, httpOnly: true });
    console.log('cookie created successfully');
  } else {
    // yes, cookie was already present 
    console.log('cookie exists', cookie);
  } 
  next(); // <-- important!
});

// let static middleware do its job
app.use(express.static(__dirname + '/public'));

Also, middleware needs to either end a request (by sending back a response), or pass the request to the next middleware. In this case, I've done the latter by calling next() when the cookie has been set.

Update

As of now the cookie parser is a seperate npm package, so instead of using

app.use(express.cookieParser());

you need to install it separately using npm i cookie-parser and then use it as:

const cookieParser = require('cookie-parser');
app.use(cookieParser());

The correct answer to this particular questions is "don't select". Sometimes you have to select or activate, but 99% of the time you don't. If your code looks like

Select something
Do something to the selection
Select something else
Do something to the selection

You probably need to refactor and consider not selecting.

The error, Method 'Range' of object '_Worksheet' failed, error 1004, that you're getting is because the sheet with the button on it doesn't have a range named "Result". Most (maybe all) properties that return an object have a default Parent object. In this case, you're using the Range property to return a Range object. Because you don't qualify the Range property, Excel uses the default.

The default Parent object can be different based on the circumstances. If your code were in a standard module, then the ActiveSheet would be the default Parent and Excel would try to resolve ActiveSheet.Range("Result"). Your code is in a sheet's class module (the sheet with the button on it). When the unqualified reference is used there, the default Parent is the sheet that's attached to that module. In this case they're the same because the sheet has to be active to click the button, but that isn't always the case.

When Excel gives the error that includes text like '_Object' (yours said '_Worksheet') it's always referring to the default Parent object - the underscore gives that away. Generally the way to fix that is to qualify the reference by being explicit about the parent. But in the case of selecting and activating when you don't need to, it's better to just refactor the code.

Here's one way to write your code without any selecting or activating.

Private Sub cmdRecord_Click()

    Dim shSource As Worksheet
    Dim shDest As Worksheet
    Dim rNext As Range

    'Me refers to the sheet whose class module you're in
    'Me.Parent refers to the workbook
    Set shSource = Me.Parent.Worksheets("BxWsn Simulation")
    Set shDest = Me.Parent.Worksheets("Reslt Record")

    Set rNext = shDest.Cells(shDest.Rows.Count, 1).End(xlUp).Offset(1, 0)

    shSource.Range("Result").Copy
    rNext.PasteSpecial xlPasteFormulasAndNumberFormats

    Application.CutCopyMode = False

End Sub

When I'm in a class module, like the sheet's class module that you're working in, I always try to do things in terms of that class. So I use Me.Parent instead of ActiveWorkbook. It makes the code more portable and prevents unexpected problems when things change.

I'm sure the code you have now runs in milliseconds, so you may not care, but avoiding selecting will definitely speed up your code and you don't have to set ScreenUpdating. That may become important as your code grows or in a different situation.

I know this is a really old thread, but it shows up at the top in Google, so here's another option.

This one is pure CSS, and doesn't require any extra HTML.

box-shadow: inset 0 0 0 1000px rgba(0,0,0,.2);

There are a surprising number of uses for the box-shadow feature.

What would be ideal what be to use a .ASPX page as a template somehow, then just tell my code to serve that page, and use the HTML returned for the email.

You could easily just construct a WebRequest to hit an ASPX page and get the resultant HTML. With a little more work, you can probably get it done without the WebRequest. A PageParser and a Response.Filter would allow you to run the page and capture the output...though there may be some more elegant ways.

    echo ${PATH}

Or change PATH just for one command:

all:
    PATH=/my/path:${PATH} cmd

Here's another one in case you don't want to use Collectors.toMap()

Map<String, Choice> result =
   choices.stream().collect(HashMap<String, Choice>::new, 
                           (m, c) -> m.put(c.getName(), c),
                           (m, u) -> {});

I've been trying to get my ASP.NET MVC controller to parse some model that i submitted to it using Postman.

I needed the following to get it to work:

• controller action

  [HttpPost]
  [PermitAllUsers]
  [Route("Models")]
  public JsonResult InsertOrUpdateModels(Model entities)
  {
      // ...
      return Json(response, JsonRequestBehavior.AllowGet);
  }
  

• a Models class

  public class Model
  {
      public string Test { get; set; }
      // ...
  }
  

• headers for Postman's request, specifically, Content-Type

  

• json in the request body

  

neat and clean

 void trimLeftTrailingSpaces(string &input) {
        input.erase(input.begin(), find_if(input.begin(), input.end(), [](int ch) {
            return !isspace(ch);
        }));
    }

    void trimRightTrailingSpaces(string &input) {
        input.erase(find_if(input.rbegin(), input.rend(), [](int ch) {
            return !isspace(ch);
        }).base(), input.end());
    }

Use Split rather than tokenizer,it will surely provide u exact output for E.g:

string name="Harry";
string salary="25000";
string namsal="Harry 25000";
string[] s=namsal.split(" ");
for(int i=0;i<s.length;i++)
{
System.out.println(s[i]);
}
if(s[0].equals("Harry"))
{
System.out.println("Task Complete");
}

After this I am sure you will get better results.....

Well, it generally depends on the shell. For bash, it marks the variable as "exportable" meaning that it will show up in the environment for any child processes you run.

Non-exported variables are only visible from the current process (the shell).

From the bash man page:

export [-fn] [name[=word]] ...
export -p

The supplied names are marked for automatic export to the environment of subsequently executed commands.

If the -f option is given, the names refer to functions. If no names are given, or if the -p option is supplied, a list of all names that are exported in this shell is printed.

The -n option causes the export property to be removed from each name.

If a variable name is followed by =word, the value of the variable is set to word.

export returns an exit status of 0 unless an invalid option is encountered, one of the names is not a valid shell variable name, or -f is supplied with a name that is not a function.

You can also set variables as exportable with the typeset command and automatically mark all future variable creations or modifications as such, with set -a.

@Test(expected = Exception.class)  

Tells Junit that exception is the expected result so test will be passed (marked as green) when exception is thrown.

For

@Test

Junit will consider test as failed if exception is thrown, provided it's an unchecked exception. If the exception is checked it won't compile and you will need to use other methods. This link might help.

If you have Model or transfer object passed to GET method but still have this error, check naming of your variables. Use entity/transfer object names in camelcase. I had BusinessTripDTO object and named it 'trip' for short. It caused this error to occure, even I had all other parts in place. Renaming varaibles to businessTripDTO in Java and Thymeleaf solved this problem for me.

Instead of manipulating the CMAKE_CXX_FLAGS strings directly (which could be done more nicely using string(APPEND CMAKE_CXX_FLAGS_DEBUG " -g3") btw), you can use add_compiler_options:

add_compile_options(
  "-Wall" "-Wpedantic" "-Wextra" "-fexceptions"
  "$<$<CONFIG:DEBUG>:-O0;-g3;-ggdb>"
)

This would add the specified warnings to all build types, but only the given debugging flags to the DEBUG build. Note that compile options are stored as a CMake list, which is just a string separating its elements by semicolons ;.

After encountering this issue and tried different method of adding the entity packaname name to EntityScan, ComponentScan etc, none of it worked.

Added the package to packageScan config in the EntityManagerFactory of the repository config. The below code gives the code based configuration as opposed to XML based ones answered above.

@Primary
@Bean(name = "entityManagerFactory")
public EntityManagerFactory entityManagerFactory() {
    LocalContainerEntityManagerFactoryBean emf = new LocalContainerEntityManagerFactoryBean();
    emf.setDataSource(dataSource);
    emf.setJpaVendorAdapter(jpaVendorAdapter);
    emf.setPackagesToScan("org.package.entity");
    emf.setPersistenceUnitName("default"); 
    emf.afterPropertiesSet();
    return emf.getObject();
}

Comparable defines a natural ordering. What this means is that you're defining it when one object should be considered "less than" or "greater than".

Suppose you have a bunch of integers and you want to sort them. That's pretty easy, just put them in a sorted collection, right?

TreeSet<Integer> m = new TreeSet<Integer>(); 
m.add(1);
m.add(3);
m.add(2);
for (Integer i : m)
... // values will be sorted

But now suppose I have some custom object, where sorting makes sense to me, but is undefined. Let's say, I have data representing districts by zipcode with population density, and I want to sort them by density:

public class District {
  String zipcode; 
  Double populationDensity;
}

Now the easiest way to sort them is to define them with a natural ordering by implementing Comparable, which means there's a standard way these objects are defined to be ordered.:

public class District implements Comparable<District>{
  String zipcode; 
  Double populationDensity;
  public int compareTo(District other)
  {
    return populationDensity.compareTo(other.populationDensity);
  }
}

Note that you can do the equivalent thing by defining a comparator. The difference is that the comparator defines the ordering logic outside the object. Maybe in a separate process I need to order the same objects by zipcode - in that case the ordering isn't necessarily a property of the object, or differs from the objects natural ordering. You could use an external comparator to define a custom ordering on integers, for example by sorting them by their alphabetical value.

Basically the ordering logic has to exist somewhere. That can be -

• in the object itself, if it's naturally comparable (extends Comparable -e.g. integers)

• supplied in an external comparator, as in the example above.

If it is not necessary turn off 'Enable 32-bit Applications' from your respective application pool of your website.

This worked for me on my local machine

simply do the select:

Select * From Times
WHERE (StartDate <= @Date) AND (EndDate >= @Date) AND
((@day = 'Monday' AND (Monday = 1))
OR (@day = 'Tuesday' AND (Tuesday = 1))
OR (Wednesday = 1))

For comparing jsons I recommend using JSONCompare: https://github.com/fslev/json-compare

// Compare by regex
String expected = "{\"a\":\".*me.*\"}";
String actual = "{\"a\":\"some text\"}";
JSONCompare.assertEquals(expected, actual);  // True

// Check expected array has no extra elements
String expected = "[1,\"test\",4,\"!.*\"]";
String actual = "[4,1,\"test\"]";
JSONCompare.assertEquals(expected, actual);  // True

// Check expected array has no numbers
String expected = "[\"\\\\\\d+\"]";
String actual = "[\"text\",\"test\"]";
JSONCompare.assertEquals(expected, actual);  // True

// Check expected array has no numbers
String expected = "[\"\\\\\\d+\"]";
String actual = "[2018]";
JSONCompare.assertNotEquals(expected, actual);  // True

From Overview of Numeric Types;

BIT[(M)]

A bit-field type. M indicates the number of bits per value, from 1 to 64. The default is 1 if M is omitted.

This data type was added in MySQL 5.0.3 for MyISAM, and extended in 5.0.5 to MEMORY, InnoDB, BDB, and NDBCLUSTER. Before 5.0.3, BIT is a synonym for TINYINT(1).

TINYINT[(M)] [UNSIGNED] [ZEROFILL]

A very small integer. The signed range is -128 to 127. The unsigned range is 0 to 255.

Additionally consider this;

BOOL, BOOLEAN

These types are synonyms for TINYINT(1). A value of zero is considered false. Non-zero values are considered true.

You can easily use index of Chrome to filter out Chrome:

var ua = navigator.userAgent.toLowerCase(); 
if (ua.indexOf('safari') != -1) { 
  if (ua.indexOf('chrome') > -1) {
    alert("1") // Chrome
  } else {
    alert("2") // Safari
  }
}

Solution is to change Delimiter.

Content of the csv file -> Note .. Also space and , in value

Values are 6 Dutch word aap,noot,mies,Piet, Gijs, Jan

Col1;Col2;Col3

a,ap;noo,t;mi es

P,iet;G ,ijs;Ja ,n



$csv = Import-Csv C:\TejaCopy.csv -Delimiter ';' 

Answer:

Write-Host $csv
@{Col1=a,ap; Col2=noo,t; Col3=mi es} @{Col1=P,iet; Col2=G ,ijs; Col3=Ja ,n}

It is possible to read a CSV file and use other Delimiter to separate each column.

It worked for my script :-)

If you want a real timer you need to use the date object.

Calculate the difference.

Format your string.

window.onload=function(){
      var start=Date.now(),r=document.getElementById('r');
      (function f(){
      var diff=Date.now()-start,ns=(((3e5-diff)/1e3)>>0),m=(ns/60)>>0,s=ns-m*60;
      r.textContent="Registration closes in "+m+':'+((''+s).length>1?'':'0')+s;
      if(diff>3e5){
         start=Date.now()
      }
      setTimeout(f,1e3);
      })();
}

Example

Jsfiddle

not so precise timer

var time=5*60,r=document.getElementById('r'),tmp=time;

setInterval(function(){
    var c=tmp--,m=(c/60)>>0,s=(c-m*60)+'';
    r.textContent='Registration closes in '+m+':'+(s.length>1?'':'0')+s
    tmp!=0||(tmp=time);
},1000);

Create a folder where you want to keep the code, and right click on it. Choose SVN Checkout... and type http://wittytwitter.googlecode.com/svn/trunk into the URL of repository field.

You can also run

svn checkout http://wittytwitter.googlecode.com/svn/trunk

from the command line in the folder you want to keep it (svn.exe has to be in your path, of course).

I don't think this can be done but I found a workaround using alias. It will only work when you place your script in your scripts directory, otherwise your alias will have an invalid name. The only point to the work around is to be able to have a function inside a file with the same name and not have to bother sourcing it before using it. Add the following code to ~/.bashrc:

alias myFunction='unalias myFunction && . myFunction && myFunction "$@"'

You can now call myFunction without sourcing it first.

Don't know if anyone is still looking here, but you can do this by going to Window menu > Preferences, then open the General list, choose keys. Scroll down the list of keys until you see "Shift Left". Click that. Below that you'll see some boxes, one of which lets you bind a key. It won't accept Shift-Tab, so I bound it to Shift-`. Apply-and-close and you're all set.

If you are working with objects track by the identifier(e.g. $index) instead of the whole object and you reload your data later, ngRepeat will not rebuild the DOM elements for items it has already rendered, even if the JavaScript objects in the collection have been substituted for new ones.

Just reset the merge commit with git reset --hard HEAD^.

If you use --no-ff git always creates a merge, even if you did not commit anything in between. Without --no-ff git will just do a fast forward, meaning your branches HEAD will be set to HEAD of the merged branch. To resolve this find the commit-id you want to revert to and git reset --hard $COMMITID.

Update:

There were 2 key parts to my question:

1. How to make a link where the text shown for the clickable link is different than the actual link that is invoked:
2. How to set up the links without having to use custom code to set the attributes on the text.

It turns out that iOS 7 added the ability to load attributed text from NSData.

I created a custom subclass of UITextView that takes advantage of the @IBInspectable attribute and lets you load contents from an RTF file directly in IB. You simply type the filename into IB and the custom class does the rest.

Here are the details:

In iOS 7, NSAttributedString gained the method initWithData:options:documentAttributes:error:. That method lets you load an NSAttributedString from an NSData object. You can first load an RTF file into NSData, then use initWithData:options:documentAttributes:error: to load that NSData into your text view. (Note that there is also a method initWithFileURL:options:documentAttributes:error: that will load an attributed string directly from a file, but that method was deprecated in iOS 9. It's safer to use the method initWithData:options:documentAttributes:error:, which wasn't deprecated.

I wanted a method that let me install clickable links into my text views without having to create any code specific to the links I was using.

The solution I came up with was to create a custom subclass of UITextView I call RTF_UITextView and give it an @IBInspectable property called RTF_Filename. Adding the @IBInspectable attribute to a property causes Interface Builder to expose that property in the "Attributes Inspector." You can then set that value from IB wihtout custom code.

I also added an @IBDesignable attribute to my custom class. The @IBDesignable attribute tells Xcode that it should install a running copy of your custom view class into Interface builder so you can see it in the graphical display of your view hierarchy. ()Unfortunately, for this class, the @IBDesignable property seems to be flaky. It worked when I first added it, but then I deleted the plain text contents of my text view and the clickable links in my view went away and I have not been able to get them back.)

The code for my RTF_UITextView is very simple. In addition to adding the @IBDesignable attribute and an RTF_Filename property with the @IBInspectable attribute, I added a didSet() method to the RTF_Filename property. The didSet() method gets called any time the value of the RTF_Filename property changes. The code for the didSet() method is quite simple:

@IBDesignable
class RTF_UITextView: UITextView
{
  @IBInspectable
  var RTF_Filename: String?
    {
    didSet(newValue)
    {
      //If the RTF_Filename is nil or the empty string, don't do anything
      if ((RTF_Filename ?? "").isEmpty)
      {
        return
      }
      //Use optional binding to try to get an URL to the
      //specified filename in the app bundle. If that succeeds, try to load
      //NSData from the file.
      if let fileURL = NSBundle.mainBundle().URLForResource(RTF_Filename, withExtension: "rtf"),
        
        //If the fileURL loads, also try to load NSData from the URL.
        let theData = NSData(contentsOfURL: fileURL)
      {
        var aString:NSAttributedString
        do
        {
          //Try to load an NSAttributedString from the data
          try
            aString = NSAttributedString(data: theData,
              options: [:],
              documentAttributes:  nil
          )
          //If it succeeds, install the attributed string into the field.
          self.attributedText = aString;
        }
        catch
        {
          print("Nerp.");
        }
      }
      
    }
  }
}

Note that if the @IBDesignable property isn't going to reliably allow you to preview your styled text in Interface builder then it might be better to set the above code up as an extension of UITextView rather than a custom subclass. That way you could use it in any text view without having to change the text view to the custom class.

See my other answer if you need to support iOS versions prior to iOS 7.

You can download a sample project that includes this new class from gitHub:

DatesInSwift demo project on Github

I use Django and it requires id column in each table if you don't want to have a headache. Unfortunately, I was careless and my table bp.geo_location_vague didn't contain this field. I initialed little trick. Step 1:

CREATE VIEW bp.geo_location_vague_vw AS
    SELECT 
        a.id, -- I change order of id column here. 
        a.in_date,
        etc
    FROM bp.geo_location_vague a

Step 2: (without create table - table will create automaticaly!)

SELECT * into bp.geo_location_vague_cp2 FROM bp.geo_location_vague_vw

Step 3:

CREATE SEQUENCE bp.tbl_tbl_id_seq;
ALTER TABLE bp.geo_location_vague_cp2 ALTER COLUMN id SET DEFAULT nextval('tbl_tbl_id_seq');
ALTER SEQUENCE bp.tbl_tbl_id_seq OWNED BY bp.geo_location_vague_cp2.id;
SELECT setval('tbl_tbl_id_seq', COALESCE(max(id), 0)) FROM bp.geo_location_vague_cp2;

Because I need have bigserial pseudotype in the table. After SELECT * into pg will create bigint type insetad bigserial.

step 4: Now we can drop the view, drop source table and rename the new table in the old name. The trick was ended successfully.

I use Log.d method also please import import android.util.Log;

Following @thomas-jungblut implementation in python, i did the same for Octave. If you find something wrong please let me know and i will fix+update.

Data comes from a txt file with the following rows:

1 10 1000
2 20 2500
3 25 3500
4 40 5500
5 60 6200

think about it as a very rough sample for features [number of bedrooms] [mts2] and last column [rent price] which is what we want to predict.

Here is the Octave implementation:

%
% Linear Regression with multiple variables
%

% Alpha for learning curve
alphaNum = 0.0005;

% Number of features
n = 2;

% Number of iterations for Gradient Descent algorithm
iterations = 10000

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
% No need to update after here
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

DATA = load('CHANGE_WITH_DATA_FILE_PATH');

% Initial theta values
theta = ones(n + 1, 1);

% Number of training samples
m = length(DATA(:, 1));

% X with one mor column (x0 filled with '1's)
X = ones(m, 1);
for i = 1:n
  X = [X, DATA(:,i)];
endfor

% Expected data must go always in the last column  
y = DATA(:, n + 1)

function gradientDescent(x, y, theta, alphaNum, iterations)
  iterations = [];
  costs = [];

  m = length(y);

  for iteration = 1:10000
    hypothesis = x * theta;

    loss = hypothesis - y;

    % J(theta)    
    cost = sum(loss.^2) / (2 * m);

    % Save for the graphic to see if the algorithm did work
    iterations = [iterations, iteration];
    costs = [costs, cost];

    gradient = (x' * loss) / m; % /m is for the average

    theta = theta - (alphaNum * gradient);
  endfor    

  % Show final theta values
  display(theta)

  % Show J(theta) graphic evolution to check it worked, tendency must be zero
  plot(iterations, costs);

endfunction

% Execute gradient descent
gradientDescent(X, y, theta, alphaNum, iterations);

long start = System.currentTimeMillis();
counter.countPrimes(1000000);
long end = System.currentTimeMillis();

System.out.println("Took : " + ((end - start) / 1000));

UPDATE

An even more accurate solution would be:

final long start = System.nanoTime();
counter.countPrimes(1000000);
final long end = System.nanoTime();

System.out.println("Took: " + ((end - start) / 1000000) + "ms");
System.out.println("Took: " + (end - start)/ 1000000000 + " seconds");

It is best practice to go asynchronous if you can do several things in parallel (no inter-dependencies). If you need it to complete to continue loading the next thing you could use synchronous, but note that this option is deprecated to avoid abuse of sync:

jQuery.ajax() method's async option deprecated, what now?

I believe it's still being used, not sure exactly. There might be even a key combination of it.

As English is written Left to Right, Arabic Right to Left, there are languages in world that are also written top to bottom. In that case a vertical tab might be useful same as the horizontal tab is used for English text.

I tried searching, but couldn't find anything useful yet.

For windows machine (I'm on windows 10), if CTRL + C (Cancel/Abort) Command on cli doesn't work, and the screen shows up like this:

Try to hit ENTER first (or any key would do) and then CTRL + C and the current process would ask if you want to terminate the batch job:

Perhaps CTRL+C only terminates the parent process while npm start runs with other child processes. Quite unsure why you have to hit that extra key though prior to CTRL+ C, but it works better than having to close the command line and start again.

A related issue you might want to check: https://github.com/mysticatea/npm-run-all/issues/74

declare class & nested struct probably in some header file

class C {
    // struct will be private without `public:` keyword
    struct S {
        // members will be public without `private:` keyword
        int sa;
        void func();
    };
    void func(S s);
};

if you want to separate the implementation/definition, maybe in some CPP file

void C::func(S s) {
    // implementation here
}
void C::S::func() { // <= note that you need the `full path` to the function
    // implementation here
}

if you want to inline the implementation, other answers will do fine.

You just need to wrap object in ()

var arr = [{_x000D_
  id: 1,_x000D_
  name: 'bill'_x000D_
}, {_x000D_
  id: 2,_x000D_
  name: 'ted'_x000D_
}]_x000D_
_x000D_
var result = arr.map(person => ({ value: person.id, text: person.name }));_x000D_
console.log(result)

for more classes adding

... className={`${classes.hello} ${classes.hello1}`...

The same problem happened to me when I use distcc to make my c++ project; Finally I solved it with export CXX="distcc g++".

If you have been trying to send a one dimentional array and jquery was converting it to comma separated values >:( then follow the code below and an actual array will be submitted to php and not all the comma separated bull**it.

Say you have to attach a single dimentional array named myvals.

jQuery('#someform').on('submit', function (e) {
    e.preventDefault();
    var data = $(this).serializeArray();

    var myvals = [21, 52, 13, 24, 75]; // This array could come from anywhere you choose 
    for (i = 0; i < myvals.length; i++) {
        data.push({
            name: "myvals[]", // These blank empty brackets are imp!
            value: myvals[i]
        });
    }

jQuery.ajax({
    type: "post",
    url: jQuery(this).attr('action'),
    dataType: "json",
    data: data, // You have to just pass our data variable plain and simple no Rube Goldberg sh*t.
    success: function (r) {
...

Now inside php when you do this

print_r($_POST);

You will get ..

Array
(
    [someinputinsidetheform] => 023
    [anotherforminput] => 111
    [myvals] => Array
        (
            [0] => 21
            [1] => 52
            [2] => 13
            [3] => 24
            [4] => 75
        )
)

Pardon my language, but there are hell lot of Rube-Goldberg solutions scattered all over the web and specially on SO, but none of them are elegant or solve the problem of actually posting a one dimensional array to php via ajax post. Don't forget to spread this solution.

AddSingleton()

AddSingleton() creates a single instance of the service when it is first requested and reuses that same instance in all the places where that service is needed.

AddScoped()

In a scoped service, with every HTTP request, we get a new instance. However, within the same HTTP request, if the service is required in multiple places, like in the view and in the controller, then the same instance is provided for the entire scope of that HTTP request. But every new HTTP request will get a new instance of the service.

AddTransient()

With a transient service, a new instance is provided every time a service instance is requested whether it is in the scope of the same HTTP request or across different HTTP requests.

I know this is not directly answering the question at hand but for anyone that comes upon this question who is using WSL running Docker for windows and cmder or conemu.

The trick is not to use Docker which is installed on windows at /mnt/c/Program Files/Docker/Docker/resources/bin/docker.exe but rather to install the ubuntu/linux Docker. It's worth pointing out that you can't run Docker itself from within WSL but you can connect to Docker for windows from the linux Docker client.

Install Docker on Linux

sudo apt-get install apt-transport-https ca-certificates curl software-properties-common
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"
sudo apt-get update
sudo apt-get install docker-ce

Connect to Docker for windows on the port 2375 which needs to be enabled from the settings in docker for windows.

docker -H localhost:2375 run -it -v /mnt/c/code:/var/app -w "/var/app" centos:7

Or set the docker_host variable which will allow you to omit the -H switch

export DOCKER_HOST=tcp://localhost:2375

You should now be able to connect interactively with a tty terminal session.

sed is a much better tool for the job: sed -n '/re/,$p' file

where re is regexp.

Another option is grep's --after-context flag. You need to pass in a number to end at, using wc on the file should give the right value to stop at. Combine this with -n and your match expression.

Here is a short and sweet answer with an example.

The issue of EOLs in mixed-platform projects has been making my life miserable for a long time. The problems usually arise when there are already files with different and mixed EOLs already in the repo. This means that:

1. The repo may have different files with different EOLs
2. Some files in the repo may have mixed EOL, e.g. a combination of CRLF and LF in the same file.

How this happens is not the issue here, but it does happen.

I ran some conversion tests on Windows for the various modes and their combinations.
Here is what I got, in a slightly modified table:

                 | Resulting conversion when       | Resulting conversion when 
                 | committing files with various   | checking out FROM repo - 
                 | EOLs INTO repo and              | with mixed files in it and
                 |  core.autocrlf value:           | core.autocrlf value:           
--------------------------------------------------------------------------------
File             | true       | input      | false | true       | input | false
--------------------------------------------------------------------------------
Windows-CRLF     | CRLF -> LF | CRLF -> LF | as-is | as-is      | as-is | as-is
Unix -LF         | as-is      | as-is      | as-is | LF -> CRLF | as-is | as-is
Mac  -CR         | as-is      | as-is      | as-is | as-is      | as-is | as-is
Mixed-CRLF+LF    | as-is      | as-is      | as-is | as-is      | as-is | as-is
Mixed-CRLF+LF+CR | as-is      | as-is      | as-is | as-is      | as-is | as-is

As you can see, there are 2 cases when conversion happens on commit (3 left columns). In the rest of the cases the files are committed as-is.

Upon checkout (3 right columns), there is only 1 case where conversion happens when:

1. core.autocrlf is true and
2. the file in the repo has the LF EOL.

Most surprising for me, and I suspect, the cause of many EOL problems is that there is no configuration in which mixed EOL like CRLF+LF get normalized.

Note also that "old" Mac EOLs of CR only also never get converted.
This means that if a badly written EOL conversion script tries to convert a mixed ending file with CRLFs+LFs, by just converting LFs to CRLFs, then it will leave the file in a mixed mode with "lonely" CRs wherever a CRLF was converted to CRCRLF.
Git will then not convert anything, even in true mode, and EOL havoc continues. This actually happened to me and messed up my files really badly, since some editors and compilers (e.g. VS2010) don't like Mac EOLs.

I guess the only way to really handle these problems is to occasionally normalize the whole repo by checking out all the files in input or false mode, running a proper normalization and re-committing the changed files (if any). On Windows, presumably resume working with core.autocrlf true.

Here is what I do to remove the validate password plugin:

1. Login to the mysql server as root mysql -h localhost -u root -p
2. Run the following sql command: uninstall plugin validate_password;
3. If last line doesn't work (new mysql release), you should execute UNINSTALL COMPONENT 'file://component_validate_password';

I would not recommend this solution for a production system. I used this solution on a local mysql instance for development purposes only.

1. Generate a random number using your favourite random-number generator
2. Multiply and divide it to get a number matching the number of characters in your code alphabet
3. Get the item at that index in your code alphabet.
4. Repeat from 1) until you have the length you want

e.g (in pseudo code)

int myInt = random(0, numcharacters)
char[] codealphabet = 'ABCDEF12345'
char random = codealphabet[i]
repeat until long enough

Another simple trick:

SELECT CONVERT(char(2), cast('2015-01-01' as datetime), 101) -- month with 2 digits
SELECT CONVERT(char(6), cast('2015-01-01' as datetime), 112) -- year (yyyy) and month (mm)

Outputs:

01
201501

if it was an IPv6 address, have a look at this: https://code.google.com/p/android/issues/detail?id=33046

Looks like there was a bug in Android that was fixed in 4.3(?).

@theczechsensation's solution is already half way there.

For those who like to exclude noisy log messages and keep the log to their app only this is the solution:

Add your exclusions to Log Tag like this: ^(?!(eglCodecCommon|tagToExclude))

Add your package name or prefix to Package Name: com.mycompany.

This way it is possible to filter for as many strings you like and keep the log to your package.

You can create an ArrayList using Cactoos (I'm one of the developers):

List<String> names = new StickyList<>(
  "Scott Fitzgerald", "Fyodor Dostoyevsky"
);

There is no guarantee that the object will actually be of class ArrayList. If you need that guarantee, do this:

ArrayList<String> list = new ArrayList<>(
  new StickyList<>(
    "Scott Fitzgerald", "Fyodor Dostoyevsky"
  )
);

Note : Use it if calculating / adding days from current date.

Be aware: this answer has issues (see comments)

var myDate = new Date();
myDate.setDate(myDate.getDate() + AddDaysHere);

It should be like

var newDate = new Date(date.setTime( date.getTime() + days * 86400000 ));

With transforms being more ubiquitously supported these days, you can do this without knowing the width/height of the popup

.popup {
    position: fixed;
    top: 50%;
    left: 50%;
    -webkit-transform: translate(-50%, -50%);
    transform: translate(-50%, -50%);
}

Easy! JSFiddle here: http://jsfiddle.net/LgSZV/

Update: Check out https://css-tricks.com/centering-css-complete-guide/ for a fairly exhaustive guide on CSS centering. Adding it to this answer as it seems to get a lot of eyeballs.

If you have LINQ:

var itemtoremove = prods.Where(item => item.ID == 1).First();
prods.Remove(itemtoremove)

egrep -ir --include=*.{php,html,js} "(document.cookie|setcookie)" .

The r flag means to search recursively (search subdirectories). The i flag means case insensitive.

If you just want file names add the l (lowercase L) flag:

egrep -lir --include=*.{php,html,js} "(document.cookie|setcookie)" .

Well, if you are going to iterate anyhow, why don't use the simplest method of all, df['Column'].values[i]

df['Column'] = ''

for i in range(len(df)):
    df['Column'].values[i] = something/update/new_value

Or if you want to compare the new values with old or anything like that, why not store it in a list and then append in the end.

mylist, df['Column'] = [], ''

for <condition>:
    mylist.append(something/update/new_value)

df['Column'] = mylist

This is how I got it to work:

To prepare the configration for WCF is hard, and sometimes a service type definition go unnoticed.

I wrote only the namespace in the service tag, so I got the same error.

<service name="ServiceNameSpace">

Do not forget, the service tag needs a fully-qualified service class name.

<service name="ServiceNameSpace.ServiceClass">

For the other folks who are like me.

I posted an answer to this already when someone else asked the same question (see How to bring back "Browser mode" in IE11?).

Read my answer there for a fuller explaination, but in short:

• They removed it deliberately, because compat mode is not actually really very good for testing compatibility.

• If you really want to test for compatibility with any given version of IE, you need to test in a real copy of that IE version. MS provide free VMs on http://modern.ie/ for you to use for this purpose.

• The only way to get compat mode in IE11 is to set the X-UA-Compatible header. When you have this and the site defaults to compat mode, you will be able to set the mode in dev tools, but only between edge or the specified compat mode; other modes will still not be available.

One option is to put the subquery in a LEFT JOIN:

select sum ( t.graduates ) - t1.summedGraduates 
from table as t
    left join 
     ( 
        select sum ( graduates ) summedGraduates, id
        from table  
        where group_code not in ('total', 'others' )
        group by id 
    ) t1 on t.id = t1.id
where t.group_code = 'total'
group by t1.summedGraduates 

Perhaps a better option would be to use SUM with CASE:

select sum(case when group_code = 'total' then graduates end) -
    sum(case when group_code not in ('total','others') then graduates end)
from yourtable

useMountEffect hook

Running a function only once after component mounts is such a common pattern that it justifies a hook of it's own that hides implementation details.

const useMountEffect = (fun) => useEffect(fun, [])

Use it in any functional component.

function MyComponent() {
    useMountEffect(function) // function will run only once after it has mounted. 
    return <div>...</div>;
}

About the useMountEffect hook

When using useEffect with a second array argument, React will run the callback after mounting (initial render) and after values in the array have changed. Since we pass an empty array, it will run only after mounting.

Assume you stored that dictionary in a variable called values. To get id in to a variable, do:

idValue = values['criteria'][0]['id']

If that json is in a file, do the following to load it:

import json
jsonFile = open('your_filename.json', 'r')
values = json.load(jsonFile)
jsonFile.close()

If that json is from a URL, do the following to load it:

import urllib, json
f = urllib.urlopen("http://domain/path/jsonPage")
values = json.load(f)
f.close()

To print ALL of the criteria, you could:

for criteria in values['criteria']:
    for key, value in criteria.iteritems():
        print key, 'is:', value
    print ''

array_splice($array, array_search(array_value, $array), 1);

Like you say, you need to show some code. :-)

A stack overflow error usually happens when your function calls nest too deeply. See the Stack Overflow Code Golf thread for some examples of how this happens (though in the case of that question, the answers intentionally cause stack overflow).

• Give every “resource” an ID
• Link things together
• Use standard methods
• Resources with multiple representations
• Communicate statelessly

It is possible to do everything just with POST and GET? Yes, is it the best approach? No, why? because we have standards methods. If you think again, it would be possible to do everything using just GET.. so why should we even bother do use POST? Because of the standards!

For example, today thinking about a MVC model, you can limit your application to respond just to specific kinds of verbs like POST, GET, PUT and DELETE. Even if under the hood everything is emulated to POST and GET, don't make sense to have different verbs for different actions?

What about sending a SIGSTOP to itself?

This should pause the process until SIGCONT is received. Which is in your case: never.

kill -STOP "$$";
# grace time for signal delivery
sleep 60;

Try this.

dpkg -s apache2 | grep Status 

dpkg -s php5 | grep Status

If you need form inside tr and inputs in every td, you can add form in td tag, and add attribute 'form' that contains id of form tag to outside inputs. Something like this:

<tr>
  <td>
    <form id='f1'>
      <input type="text">
    </form>
  </td>
  <td>
    <input form='f1' type="text">
  </td>
</tr>

You can use the JANSI library to render ANSI escape sequences in Windows.

My issue has been resolved after I deleted the redundant assembly files from the bin folder.

See a mistake? Hint: Excel is accepting indexing from 1, but not from 0 as C# does.

In case it helps others, the option I prefer, which is not listed here, uses Guava's Maps functionality:

public enum Vebosity {
    BRIEF("BRIEF"),
    NORMAL("NORMAL"),
    FULL("FULL");

    private String value;
    private Verbosity(final String value) {
        this.value = value;
    }

    public String getValue() {
        return this.value;
    }

    private static ImmutableMap<String, Verbosity> reverseLookup = 
            Maps.uniqueIndex(Arrays.asList(Verbosity.values()), Verbosity::getValue);

    public static Verbosity fromString(final String id) {
        return reverseLookup.getOrDefault(id, NORMAL);
    }
}

With the default you can use null, you can throw IllegalArgumentException or your fromString could return an Optional, whatever behavior you prefer.

If you are verifying if a reference of a List or Map value of Object is an instance of a Collection, just create an instance of required List and get its class...

Set<Object> setOfIntegers = new HashSet(Arrays.asList(2, 4, 5));
assetThat(setOfIntegers).instanceOf(new ArrayList<Integer>().getClass());

Set<Object> setOfStrings = new HashSet(Arrays.asList("my", "name", "is"));
assetThat(setOfStrings).instanceOf(new ArrayList<String>().getClass());

The easiest way to calculate number of neurons in one layer is: Param value / (number of units * 4)

• Number of units is in predictivemodel.add(Dense(514,...)
• Param value is Param in model.summary() function

For example in Paul Lo's answer , number of neurons in one layer is 264710 / (514 * 4 ) = 130

Arbitrary Indentation of any Option

If you just want to indent random, arbitrary <option /> elements, you can use  , which has the greatest cross-browser compatibility of the solutions posted here...

.optionGroup {
  font-weight: bold;
  font-style: italic;
}

<select>
    <option class="optionGroup" selected disabled>Choose one</option>
    <option value="sydney" class="optionChild">&nbsp;&nbsp;&nbsp;&nbsp;Sydney</option>
    <option value="melbourne" class="optionChild">&nbsp;&nbsp;&nbsp;&nbsp;Melbourne</option>
    <option value="cromwell" class="optionChild">&nbsp;&nbsp;&nbsp;&nbsp;Cromwell</option>
    <option value="queenstown" class="optionChild">&nbsp;&nbsp;&nbsp;&nbsp;Queenstown</option>
</select>

Ordered Indentation of Options

But if you have some sorted, ordered structure to your data, then it is recommended that you use the <optgroup/> syntax....

The HTML element creates a grouping of options within a element. (Source: MDN Web Docs: <optgroup>)

<select>
    <optgroup label="Australia" default selected>
        <option value="sydney">Sydney</option>
        <option value="melbourne">Melbourne</option>
    </optgroup>
    <optgroup label="United Kingdom">
        <option value="london">London</option>
        <option value="glasgow">Glasgow</option>
    </optgroup>
</select>

Unfortunately, only one <optgroup /> level is allowed and currently supported by browsers today. (Source: w3.org.) Personally, I would consider that part of the spec broken, but you can always extend to third, fourth, etc., levels of indentation with using the   trick up above.

&& works by stringing-together multiple selectors like-so:

<div class="class1 class2"></div>

div.class1.class2
{
  /* foo */
}

Another example:

<input type="radio" class="class1" />

input[type="radio"].class1
{
  /* foo */
}

|| works by separating multiple selectors with commas like-so:

<div class="class1"></div>
<div class="class2"></div>

div.class1,
div.class2
{
  /* foo */
}

Use -B, -A or -C option

grep --help
...
-B, --before-context=NUM  print NUM lines of leading context
-A, --after-context=NUM   print NUM lines of trailing context
-C, --context=NUM         print NUM lines of output context
-NUM                      same as --context=NUM
...

Here is a method that does not require editing the code and works regardless of the number of characters.

String text = 
  java.text.MessageFormat.format(
    "You're about to delete {0} rows.".replaceAll("'", "''"), 5);

the problem is in the MatInputModule:

exports: [
    MatInputModule
  ]

It sounds like you need an OR instead:

<button type="submit" [disabled]="!validate || !SAForm.valid">Add</button>

This will disable the button if not validate or if not SAForm.valid.

It's because of the Python version. In Python 3 it's import Queue as queue; on the contrary in Python 2.x it's import queue. If you want it for both environments you may use something below as mentioned here

I use the following helper method, which you can bind to your list.

    ''' <summary>
    ''' Returns enumeration as a sortable list.
    ''' </summary>
    ''' <param name="t">GetType(some enumeration)</param>
    Public Shared Function GetEnumAsList(ByVal t As Type) As SortedList(Of String, Integer)

        If Not t.IsEnum Then
            Throw New ArgumentException("Type is not an enumeration.")
        End If

        Dim items As New SortedList(Of String, Integer)
        Dim enumValues As Integer() = [Enum].GetValues(t)
        Dim enumNames As String() = [Enum].GetNames(t)

        For i As Integer = 0 To enumValues.GetUpperBound(0)
            items.Add(enumNames(i), enumValues(i))
        Next

        Return items

    End Function

Run apt-get install build-essential on your system.

The list method index will return -1 if the item is not present, and will return the index of the item in the list if it is present. Alternatively in an if statement you can do the following:

if myItem in list:
    #do things

You can also check if an element is not in a list with the following if statement:

if myItem not in list:
    #do things

According to this documentation:

DESC MY_TABLE

is equivalent to

SELECT column_name "Name", nullable "Null?", concat(concat(concat(data_type,'('),data_length),')') "Type" FROM user_tab_columns WHERE table_name='TABLE_NAME_TO_DESCRIBE';

I've roughly translated that to the SQL Server equivalent for you - just make sure you're running it on the EX database.

SELECT column_name AS [name],
       IS_NULLABLE AS [null?],
       DATA_TYPE + COALESCE('(' + CASE WHEN CHARACTER_MAXIMUM_LENGTH = -1
                                  THEN 'Max'
                                  ELSE CAST(CHARACTER_MAXIMUM_LENGTH AS VARCHAR(5))
                                  END + ')', '') AS [type]
FROM   INFORMATION_SCHEMA.Columns
WHERE  table_name = 'EMP_MAST'

Here are two methods to get more than 1 column in a scalar subquery (or inline subquery) and querying the lookup table only once. This is a bit convoluted but can be the very efficient in some special cases.

1. You can use concatenation to get several columns at once:

   SELECT x, 
          regexp_substr(yz, '[^^]+', 1, 1) y,
          regexp_substr(yz, '[^^]+', 1, 2) z
     FROM (SELECT a.x,
                  (SELECT b.y || '^' || b.z yz
                     FROM b
                    WHERE b.v = a.v)
                     yz
             FROM a)
   

   You would need to make sure that no column in the list contain the separator character.

2. You could also use SQL objects:

   CREATE OR REPLACE TYPE b_obj AS OBJECT (y number, z number);
   
   SELECT x, 
          v.yz.y y,
          v.yz.z z
     FROM (SELECT a.x,
                  (SELECT b_obj(y, z) yz
                     FROM b
                    WHERE b.v = a.v)
                     yz
             FROM a) v
   

You can use jQuery to achieve this using simple $.get method. .html work like innerHtml and replace the content of your div.

$.get("/YourUrl", {},
      function (returnedHtml) {
      $("#here").html(returnedHtml);
});

And call this using javascript setInterval method.

I had a problem with the answer by @mwaskorn, namely that

g.set_xticklabels(rotation=30)

fails, because this also requires the labels. A bit easier than the answer by @Aman is to just add

plt.xticks(rotation=45)
