Instead of Windows PowerShell, find the item in the Start Menu called SharePoint 2013 Management Shell:

The best answer I can find, is in one of the comments here. Adding it to the answer so that someone won't miss the comment and should definitely try this out. It fixed the issue for me.

We need to map the solution folder to a drive using the "subst" command in command prompt- e.g., subst z:

And then open the solution from this drive (z in this case). This would shorten the path as much as possible and could solve the lengthy filename issue.

Thank you to all the commenters on this page. When I first installed the latest TortoiseSVN I got this error.

I was using the latest version, so decided to downgrade to 1.5.9 (as the rest of my colleagues were using) and this got it to work. Then, once built, my machine was moved onto another subnet and the problem started again.

I went to TortoiseSVN->Settings->Saved Data and cleared the Authentication data. After this it worked fine.

Why is it that you need to place columns you create yourself (for example "select 1 as number") after HAVING and not WHERE in MySQL?

WHERE is applied before GROUP BY, HAVING is applied after (and can filter on aggregates).

In general, you can reference aliases in neither of these clauses, but MySQL allows referencing SELECT level aliases in GROUP BY, ORDER BY and HAVING.

And are there any downsides instead of doing "WHERE 1" (writing the whole definition instead of a column name)

If your calculated expression does not contain any aggregates, putting it into the WHERE clause will most probably be more efficient.

In order to move a View anywhere on the screen, I would recommend placing it in a full screen layout. By doing so, you won't have to worry about clippings or relative coordinates.

You can try this sample code:

main.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" android:id="@+id/rootLayout">

    <Button
        android:id="@+id/btn1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="MOVE" android:layout_centerHorizontal="true"/>

    <ImageView
        android:id="@+id/img1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/ic_launcher" android:layout_marginLeft="10dip"/>
    <ImageView
        android:id="@+id/img2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/ic_launcher" android:layout_centerVertical="true" android:layout_alignParentRight="true"/>
    <ImageView
        android:id="@+id/img3"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/ic_launcher" android:layout_marginLeft="60dip" android:layout_alignParentBottom="true" android:layout_marginBottom="100dip"/>

    <LinearLayout
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:orientation="vertical" android:clipChildren="false" android:clipToPadding="false">

        <ImageView
            android:id="@+id/img4"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:src="@drawable/ic_launcher" android:layout_marginLeft="60dip" android:layout_marginTop="150dip"/>
    </LinearLayout>

</RelativeLayout>

Your activity

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    ((Button) findViewById( R.id.btn1 )).setOnClickListener( new OnClickListener()
    {
        @Override
        public void onClick(View v)
        {
            ImageView img = (ImageView) findViewById( R.id.img1 );              
            moveViewToScreenCenter( img );
            img = (ImageView) findViewById( R.id.img2 );
            moveViewToScreenCenter( img );
            img = (ImageView) findViewById( R.id.img3 );                
            moveViewToScreenCenter( img );
            img = (ImageView) findViewById( R.id.img4 );
            moveViewToScreenCenter( img );
        }
    });
}

private void moveViewToScreenCenter( View view )
{
    RelativeLayout root = (RelativeLayout) findViewById( R.id.rootLayout );
    DisplayMetrics dm = new DisplayMetrics();
    this.getWindowManager().getDefaultDisplay().getMetrics( dm );
    int statusBarOffset = dm.heightPixels - root.getMeasuredHeight();

    int originalPos[] = new int[2];
    view.getLocationOnScreen( originalPos );

    int xDest = dm.widthPixels/2;
    xDest -= (view.getMeasuredWidth()/2);
    int yDest = dm.heightPixels/2 - (view.getMeasuredHeight()/2) - statusBarOffset;

    TranslateAnimation anim = new TranslateAnimation( 0, xDest - originalPos[0] , 0, yDest - originalPos[1] );
    anim.setDuration(1000);
    anim.setFillAfter( true );
    view.startAnimation(anim);
}

The method moveViewToScreenCenter gets the View's absolute coordinates and calculates how much distance has to move from its current position to reach the center of the screen. The statusBarOffset variable measures the status bar height.

I hope you can keep going with this example. Remember that after the animation your view's position is still the initial one. If you tap the MOVE button again and again the same movement will repeat. If you want to change your view's position do it after the animation is finished.

You are missing that rsync can also compare files by checksum.

--size-only means that rsync will skip files that match in size, even if the timestamps differ. This means it will synchronise fewer files than the default behaviour. It will miss any file with changes that don't affect the overall file size. If you have something that changes the dates on files without changing the files, and you don't want rsync to spend lots of time checksumming those files to discover they haven't changed, this is the option to use.

--ignore-times means that rsync will checksum every file, even if the timestamps and file sizes match. This means it will synchronise more files than the default behaviour. It will include changes to files even where the file size is the same and the modification date/time has been reset to the original value. Checksumming every file means it has to be entirely read from disk, which may be slow. Some build pipelines will reset timestamps to a specific date (like 1970-01-01) to ensure that the final build file is reproducible bit for bit, e.g. when packed into a tar file that saves the timestamps.

ObjectType instance = (ObjectType)Activator.CreateInstance(objectType);

The Activator class has a generic variant that makes this a bit easier:

ObjectType instance = Activator.CreateInstance<ObjectType>();

try this:

.topics tr { line-height: 14px; }

You could create a color using the static FromArgb method:

Color redColor = Color.FromArgb(255, 0, 0);

You can also specify the alpha using the following overload.

1. Events declared in a class have their += and -= access automatically locked via a lock(this) to make them thread safe (static events are locked on the typeof the class). Events declared in a struct do not have their += and -= access automatically locked. A lock(this) for a struct would not work since you can only lock on a reference type expression.

2. Creating a struct instance cannot cause a garbage collection (unless the constructor directly or indirectly creates a reference type instance) whereas creating a reference type instance can cause garbage collection.

3. A struct always has a built-in public default constructor.

   class DefaultConstructor
   {
       static void Eg()
       {
           Direct     yes = new   Direct(); // Always compiles OK
           InDirect maybe = new InDirect(); // Compiles if constructor exists and is accessible
           //...
       }
   }
   

   This means that a struct is always instantiable whereas a class might not be since all its constructors could be private.

   class NonInstantiable
   {
       private NonInstantiable() // OK
       {
       }
   }
   
   struct Direct
   {
       private Direct() // Compile-time error
       {
       }
   }
   

4. A struct cannot have a destructor. A destructor is just an override of object.Finalize in disguise, and structs, being value types, are not subject to garbage collection.

   struct Direct
   {
       ~Direct() {} // Compile-time error
   }
   class InDirect
   {
       ~InDirect() {} // Compiles OK
   }
   
   And the CIL for ~Indirect() looks like this:
   
   .method family hidebysig virtual instance void
           Finalize() cil managed
   {
     // ...
   } // end of method Indirect::Finalize
   

5. A struct is implicitly sealed, a class isn't.
   A struct can't be abstract, a class can.
   A struct can't call : base() in its constructor whereas a class with no explicit base class can.
   A struct can't extend another class, a class can.
   A struct can't declare protected members (for example, fields, nested types) a class can.
   A struct can't declare abstract function members, an abstract class can.
   A struct can't declare virtual function members, a class can.
   A struct can't declare sealed function members, a class can.
   A struct can't declare override function members, a class can.
   The one exception to this rule is that a struct can override the virtual methods of System.Object, viz, Equals(), and GetHashCode(), and ToString().
   

This question needs a proper answer:

Just use the standard package site, which was made for this job!

and here is how (plagiating my own answer to my own question on the very same topic):

1. Open a Python prompt and type

>>> import site
>>> site.USER_SITE
'C:\\Users\\ojdo\\AppData\\Roaming\\Python\\Python37\\site-packages'
...

2. Create this folder if it does not exist yet:

...
>>> import os
>>> os.makedirs(site.USER_SITE)
...

3. Create a file sitecustomize.py in this folder containing the content of FIND_MY_PACKAGES, either manually or using something like the following code. Of course, you have to change C:\My_Projects to the correct path to your custom import location.

...
>>> FIND_MY_PACKAGES = """
import site
site.addsitedir(r'C:\My_Projects')
"""
>>> filename = os.path.join(site.USER_SITE, 'sitecustomize.py')
>>> with open(filename, 'w') as outfile:
...     print(FIND_MY_PACKAGES, file=outfile)

And the next time you start Python, C:\My_Projects is present in your sys.path, without having to touch system-wide settings. Bonus: the above steps work on Linux, too!

I have tried both the options suggested by Michael Munsey and works for me.

I wanted to provide another option to view the filtered tables. Mouse Right Click your table trees node and Select "Apply Filter" and check "Include Synonyms" check box and click Okay. That's it, you should be able to view the tables right there. It works for me.

After this, From File Menu select Save Book ,from next menu select "Excel 97-2003 Add-In (*.xla)

It will save as Excel Add-In. that will be available till the Ms.Office Installation to that machine.

Now Open any Excel File in any Cell type =WordNum(<your numeric value or cell reference>)

you will see a Words equivalent of the numeric value.

I wrote a method to delete lines from files.

This program uses using System.IO.

See my code:

void File_DeleteLine(int Line, string Path)
{
    StringBuilder sb = new StringBuilder();
    using (StreamReader sr = new StreamReader(Path))
    {
        int Countup = 0;
        while (!sr.EndOfStream)
        {
            Countup++;
            if (Countup != Line)
            {
                using (StringWriter sw = new StringWriter(sb))
                {
                    sw.WriteLine(sr.ReadLine());
                }
            }
            else
            {
                sr.ReadLine();
            }
        }
    }
    using (StreamWriter sw = new StreamWriter(Path))
    {
        sw.Write(sb.ToString());
    }
}

Very simple option in case you have many individual columns to delete in a data table and you want to avoid typing in all column names #careadviced

dt <- dt[, -c(1,4,6,17,83,104)]

This will remove columns based on column number instead.

It's obviously not as efficient because it bypasses data.table advantages but if you're working with less than say 500,000 rows it works fine

Use the following setting and you will be all set. Go to Window --> Preference --> General --> Network Connection --> select Direct from drop down

Have you got access to SSH?

You can use this command in shell to backup an entire database:

mysqldump -u [username] -p[password] [databasename] > [filename.sql]

This is actually one command followed by the > operator, which says, "take the output of the previous command and store it in this file."

Note: The lack of a space between -p and the mysql password is not a typo. However, if you leave the -p flag present, but the actual password blank then you will be prompted for your password. Sometimes this is recommended to keep passwords out of your bash history.

You can not do that directly. You need to use std::remove algorithm to move the element to be erased to the end of the vector and then use erase function. Something like: myVector.erase(std::remove(myVector.begin(), myVector.end(), 8), myVec.end());. See this erasing elements from vector for more details.

Yet another method:

s = 'hello'

h = ''.join([hex(ord(i)) for i in s]);

# outputs: '0x680x650x6c0x6c0x6f'

This basically splits the string into chars, does the conversion through hex(ord(char)), and joins the chars back together. In case you want the result without the prefix 0x then do:

h = ''.join([str(hex(ord(i)))[2:4] for i in s]);

# outputs: '68656c6c6f'

Tested with Python 3.5.3.

You can use the expect utility to drive all programs that read from a tty (as opposed to stdin, which is what passwd does). Expect comes with ready to run examples for all sorts of interactive problems, like passwd entry.

You should be able to do something like this:

Same issue. In my case I solved setting the project as the "StartUp Project".

Rails destroy name

rake db:rollback

C also does a good job at not making anything ambiguous.

Sure the dot could be overloaded to mean both things, but the arrow makes sure that the programmer knows that he's operating on a pointer, just like when the compiler won't let you mix two incompatible types.

Just add this in your dependencies

compile 'org.apache.httpcomponents:httpcore:4.4.1'
compile 'org.apache.httpcomponents:httpclient:4.5'

Finally

dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])    
testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:23.0.1'
compile 'com.android.support:design:23.0.1'
compile 'org.apache.httpcomponents:httpcore:4.4.1'
compile 'org.apache.httpcomponents:httpclient:4.5'
}

And also add this code:

 android {
    useLibrary 'org.apache.http.legacy'
         }

FYI

Specify requirement for Apache HTTP Legacy library If your app is targeting API level 28 (Android 9.0) or above, you must include the following declaration within the element of AndroidManifest.xml.

 <uses-library
      android:name="org.apache.http.legacy"
      android:required="false" />

The answer is there, git is telling you to fetch first.

Probably somebody else has pushed to master already, and your commit is behind. Therefore you have to fetch, merge the changeset, and then you'll be able to push again.

If you don't (or even worse, if you force it by using the --force option), you can mess up the commit history.

EDIT: I get into more detail about the last point, since a guy here just gave the Very Bad Advice of using the --force option.

As git is a DVCS, ideally many other developers are working on the same project as you, using the same repository (or a fork of it). If you overwrite forcefully with your changeset, your repository will mismatch other people's, because "you rewrote history". You will make other people unhappy and the repository will suffer. Probably a kitten in the world will cry, too.

TL;DR

1. If you want to solve, fetch first (and then merge).
2. If you want to hack, use the --force option.

You asked for the former, though. Go for 1) always, even if you will always use git by yourself, because it is a good practice.

my_function.func_name

There are also other fun properties of functions. Type dir(func_name) to list them. func_name.func_code.co_code is the compiled function, stored as a string.

import dis
dis.dis(my_function)

will display the code in almost human readable format. :)

You can use the whois service. On a UNIX like operating system you would execute the following command. Alternatively you can do it on the web at http://www.internic.net/whois.html.

You can iterate over a dictionary and grab an index with for-in and enumerate (like others have said, there is no guarantee it will come out ordered like below)

let dict = ["c": 123, "d": 045, "a": 456]

for (index, entry) in enumerate(dict) {
    println(index)   // 0       1        2
    println(entry)   // (d, 45) (c, 123) (a, 456)
}

If you want to sort first..

var sortedKeysArray = sorted(dict) { $0.0 < $1.0 }
println(sortedKeysArray)   // [(a, 456), (c, 123), (d, 45)]

var sortedValuesArray = sorted(dict) { $0.1 < $1.1 }
println(sortedValuesArray) // [(d, 45), (c, 123), (a, 456)]

then iterate.

for (index, entry) in enumerate(sortedKeysArray) {
    println(index)    // 0   1   2
    println(entry.0)  // a   c   d
    println(entry.1)  // 456 123 45
}

If you want to create an ordered dictionary, you should look into Generics.

In case you want to use the class and pseudo-class:

.simple-control is your css class

:disabled is pseudo class

select.simple-control:disabled{
         /*For FireFox*/
        -webkit-appearance: none;
        /*For Chrome*/
        -moz-appearance: none;
}

/*For IE10+*/
select:disabled.simple-control::-ms-expand {
        display: none;
}

Well, this should really be broken into 2 parts:

1. Can you pair 2 Bluetooth devices without going through a Bluetooth pairing handshake? No, you can't. That's baked into the protocol so there is no way around this.
2. Can you perform the handshake without a user interface? Yes, you can: that's just code.

I'm not sure how you do it in Windows land, but in *nix land there are functions buried in the Bluez stack that let you receive notifications about when a new device appears, and send it the pairing code (clearly there have to be these functions: those are what the user interface use). Given sufficient time and experience I'm sure you could figure out how to write your own version of the Bluetooth Settings app that somehow:

• Detected a new device had arrived
• Looked at the name/bluetooth mac address and checked some internal database for the pairing code to use.
• Sent the pairing code and completed the operation

All without having to pop up a user interface.

If you go ahead and write the code I'd LOVE to get my hands on it.

.vscode/launch.json file is only used by Visual Studio as well as /Properties/launchSettings.json file. Don't use these files in production.

The launchSettings.json file:

1. Is only used on the local development machine.
2. Is not deployed.

3. contains profile settings.

   • Environment values set in launchSettings.json override values set in the system environment

To use a file 'appSettings.QA.json' for example. You can use 'ASPNETCORE_ENVIRONMENT'. Follow the steps below.

1. Add a new Environment Variable on the host machine and call it 'ASPNETCORE_ENVIRONMENT'. Set its value to 'QA'.
2. Create a file 'appSettings.QA.json' in your project. Add your configuration here.
3. Deploy to the machine in step 1. Confirm 'appSettings.QA.json' is deployed.

Are you sure that floated block-level elements are the best solution to this problem?

Often with CSS difficulties in my experience it turns out that the reason I can't see a way of doing the thing I want is that I have got caught in a tunnel-vision with regard to my markup ( thinking "how can I make these elements do this?" ) rather than going back and looking at what exactly it is I need to achieve and maybe reworking my html slightly to facilitate that.

People will offer you obfuscators, but no amount of obfuscation can prevent someone from getting at your code. None. If your computer can run it, or in the case of movies and music if it can play it, the user can get at it. Even compiling it to machine code just makes the job a little more difficult. If you use an obfuscator, you are just fooling yourself. Worse, you're also disallowing your users from fixing bugs or making modifications.

Music and movie companies haven't quite come to terms with this yet, they still spend millions on DRM.

In interpreted languages like PHP and Perl it's trivial. Perl used to have lots of code obfuscators, then we realized you can trivially decompile them.

perl -MO=Deparse some_program

PHP has things like DeZender and Show My Code.

My advice? Write a license and get a lawyer. The only other option is to not give out the code and instead run a hosted service.

See also the perlfaq entry on the subject.

this is old but for help :

you can also use the stringReader stream

string str = "asasdkopaksdpoadks";
StringReader TheStream = new StringReader( str );

//HashSet allows only the unique values to the list
HashSet<int> uniqueList = new HashSet<int>();

var a = uniqueList.Add(1);
var b = uniqueList.Add(2);
var c = uniqueList.Add(3);
var d = uniqueList.Add(2); // should not be added to the list but will not crash the app

//Dictionary allows only the unique Keys to the list, Values can be repeated
Dictionary<int, string> dict = new Dictionary<int, string>();

dict.Add(1,"Happy");
dict.Add(2, "Smile");
dict.Add(3, "Happy");
dict.Add(2, "Sad"); // should be failed // Run time error "An item with the same key has already been added." App will crash

//Dictionary allows only the unique Keys to the list, Values can be repeated
Dictionary<string, int> dictRev = new Dictionary<string, int>();

dictRev.Add("Happy", 1);
dictRev.Add("Smile", 2);
dictRev.Add("Happy", 3); // should be failed // Run time error "An item with the same key has already been added." App will crash
dictRev.Add("Sad", 2);

SELECT name

Another great implementation is jQuery History which will use the native onhashchange event if it is supported by the browser, if not it will use an iframe or interval appropriately for the browser to ensure all the expected functionality is successfully emulated. It also provides a nice interface to bind to certain states.

Another project worth noting as well is jQuery Ajaxy which is pretty much an extension for jQuery History to add ajax to the mix. As when you start using ajax with hashes it get's quite complicated!

You can also do like the following: This will draw a 10x1 random matrix data on the plot for 50 cycles of the for loop.

import matplotlib.pyplot as plt
import numpy as np

plt.ion()
for i in range(50):
    y = np.random.random([10,1])
    plt.plot(y)
    plt.draw()
    plt.pause(0.0001)
    plt.clf()

java.util.Date is independent of the timezone. When you print cal_Two though the Calendar instance has got its timezone set to UTC, cal_Two.getTime() would return a Date instance which does not have a timezone (and is always in the default timezone)

Calendar cal_Two = Calendar.getInstance(TimeZone.getTimeZone("UTC"));
System.out.println(cal_Two.getTime());
System.out.println(cal_Two.getTimeZone());

Output:

 Sat Jan 25 16:40:28 IST 2014
    sun.util.calendar.ZoneInfo[id="UTC",offset=0,dstSavings=0,useDaylight=false,transitions=0,lastRule=null] 

From the javadoc of TimeZone.setDefault()

Sets the TimeZone that is returned by the getDefault method. If zone is null, reset the default to the value it had originally when the VM first started.

Hence, moving your setDefault() before cal_Two is instantiated you would get the correct result.

TimeZone.setDefault(TimeZone.getTimeZone("UTC"));
Calendar cal_Two = Calendar.getInstance(TimeZone.getTimeZone("UTC"));
System.out.println(cal_Two.getTime());

Calendar cal_Three = Calendar.getInstance();
System.out.println(cal_Three.getTime());

Output:

Sat Jan 25 11:15:29 UTC 2014
Sat Jan 25 11:15:29 UTC 2014

I got this problem recently. Here what I do:

1. Restart MongoDb: sudo service mongod restart
2. Restart My NodeJS APP. I use pm2 to handle this pm2 restart [your-app-id]. To get ID use pm2 list

#include<iostream>
#include<conio.h>
#include<stdlib.h>
using namespace std;
void displayBinary(int n)
{
       char bistr[1000];
       itoa(n,bistr,2);       //2 means binary u can convert n upto base 36
       printf("%s",bistr);

}

int main()
{
    int n;
    cin>>n;
    displayBinary(n);
    getch();
    return 0;

The answer is now obsolete. See this answer.

maven-compiler-plugin depends on the old version of ASM which does not support Java 10 (and Java 11) yet. However, it is possible to explicitly specify the right version of ASM:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-compiler-plugin</artifactId>
    <version>3.7.0</version>
    <configuration>
        <release>10</release>
    </configuration>
    <dependencies>
        <dependency>
            <groupId>org.ow2.asm</groupId>
            <artifactId>asm</artifactId>
            <version>6.2</version> <!-- Use newer version of ASM -->
        </dependency>
    </dependencies>

This poblem is solved for me after Run as administrator the Andorid Studio

Gradle is a build system running on Android Studio.

In other languages for example:

• Ant and Maven of Java
• Rake of Ruby
• A-A-P of C
• NAnt of .NET
• Make in Linux

To specify a directory to search for (binary) libraries, you just use -L:

-L/data[...]/lib

To specify the actual library name, you use -l:

-lfoo  # (links libfoo.a or libfoo.so)

To specify a directory to search for include files (different from libraries!) you use -I:

-I/data[...]/lib

So I think what you want is something like

g++ -g -Wall -I/data[...]/lib testing.cpp fileparameters.cpp main.cpp -o test

These compiler flags (amongst others) can also be found at the GNU GCC Command Options manual:

• 3.16 Options for Directory Search

To trigger the onClick event on a radio-button invoke the click() method on the DOM element:

document.getElementById("radioButton").click()

using jquery:

$("#radioButton").click()

AngularJs:

angular.element('#radioButton').trigger('click')

Since in your situation you only want to notify the user with a short and simple message, a Toast would make for a better user experience.

Toast.makeText(getApplicationContext(), "Data saved", Toast.LENGTH_LONG).show();

Update: A Snackbar is recommended now instead of a Toast for Material Design apps.

If you have a more lengthy message that you want to give the reader time to read and understand, then you should use a DialogFragment. (The documentation currently recommends wrapping your AlertDialog in a fragment rather than calling it directly.)

Make a class that extends DialogFragment:

public class MyDialogFragment extends DialogFragment {
    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {

        // Use the Builder class for convenient dialog construction
        AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
        builder.setTitle("App Title");
        builder.setMessage("This is an alert with no consequence");
        builder.setPositiveButton("OK", new DialogInterface.OnClickListener() {
            public void onClick(DialogInterface dialog, int id) {
                // You don't have to do anything here if you just 
                // want it dismissed when clicked
            }
        });

        // Create the AlertDialog object and return it
        return builder.create();
    }
}

Then call it when you need it in your activity:

DialogFragment dialog = new MyDialogFragment();
dialog.show(getSupportFragmentManager(), "MyDialogFragmentTag");

You can sort on multiple columns as per Steve Tjoa's method by using a stable sort like mergesort and sorting the indices from the least significant to the most significant columns:

a = a[a[:,2].argsort()] # First sort doesn't need to be stable.
a = a[a[:,1].argsort(kind='mergesort')]
a = a[a[:,0].argsort(kind='mergesort')]

This sorts by column 0, then 1, then 2.

According to the RFC that introduced the operator, $a <=> $b evaluates to:

• 0 if $a == $b
• -1 if $a < $b
• 1 if $a > $b

which seems to be the case in practice in every scenario I've tried, although strictly the official docs only offer the slightly weaker guarantee that $a <=> $b will return

an integer less than, equal to, or greater than zero when $a is respectively less than, equal to, or greater than $b

Regardless, why would you want such an operator? Again, the RFC addresses this - it's pretty much entirely to make it more convenient to write comparison functions for usort (and the similar uasort and uksort).

usort takes an array to sort as its first argument, and a user-defined comparison function as its second argument. It uses that comparison function to determine which of a pair of elements from the array is greater. The comparison function needs to return:

an integer less than, equal to, or greater than zero if the first argument is considered to be respectively less than, equal to, or greater than the second.

The spaceship operator makes this succinct and convenient:

$things = [
    [
        'foo' => 5.5,
        'bar' => 'abc'
    ],
    [
        'foo' => 7.7,
        'bar' => 'xyz'
    ],
    [
        'foo' => 2.2,
        'bar' => 'efg'
    ]
];

// Sort $things by 'foo' property, ascending
usort($things, function ($a, $b) {
    return $a['foo'] <=> $b['foo'];
});

// Sort $things by 'bar' property, descending
usort($things, function ($a, $b) {
    return $b['bar'] <=> $a['bar'];
});

More examples of comparison functions written using the spaceship operator can be found in the Usefulness section of the RFC.

Updating @Crashalot's answer for Swift 3.x:

override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
    if let touch = touches.first {
        let currentPoint = touch.location(in: self)
        // do something with your currentPoint
    }
}

override func touchesMoved(_ touches: Set<UITouch>, with event: UIEvent?) {
    if let touch = touches.first {
        let currentPoint = touch.location(in: self)
        // do something with your currentPoint
    }
}

override func touchesEnded(_ touches: Set<UITouch>, with event: UIEvent?) {
    if let touch = touches.first {
        let currentPoint = touch.location(in: self)
        // do something with your currentPoint
    }
}

My understanding is that the underscore is technically valid. Check out:

https://developer.mozilla.org/en/underscores_in_class_and_id_names

"...errata to the specification published in early 2001 made underscores legal for the first time."

The article linked above says never use them, then gives a list of browsers that don't support them, all of which are, in terms of numbers of users at least, long-redundant.

The following worked for me when changing Author and Committer of a commit.

git push -f origin master

Git was smart enough to figure out that these were commits of identical deltas which only differed in the meta information section.

Both the local and remote heads pointed to the commits in question.

The problem is because you haven't set JAVA_HOME in Mac properly. In order to do that, you should do set it like this:

export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_40.jdk/Contents/Home

In my case my JDK installation is jdk1.8.0_40, make sure you type yours.

Then you can use maven commands.

import os#must import this library
if os.path.exists('TwitterDB.csv'):
        os.remove('TwitterDB.csv') #this deletes the file
else:
        print("The file does not exist")#add this to prevent errors

I had a similar problem, and instead of overwriting my existing file using the different 'modes', I just deleted the file before using it again, so that it would be as if I was appending to a new file on each run of my code.

I developed an algorithm for this as part of a science project once.

You basically recursively divide the board into a bunch of overlapping 2x2 rects, testing the different possible combinations for winning on a 2x2 square.

It is slow, but it has the advantage of working on any sized board, with fairly linear memory requirements.

I wish I could find my implementation

The first line moves the cursor to the last non-empty row in the column. The second line prints that columns row.

Selection.End(xlDown).Select
MsgBox(ActiveCell.Row)

Rather than explicitly include all possible characters, you could do a regex to check for the presence of illegal characters, and report an error then. Ideally your application should name the files exactly as the user wishes, and only cry foul if it stumbles across an error.

public byte[] loadBinaryFile (String name) {
    try {

        DataInputStream dis = new DataInputStream(new FileInputStream(name));
        byte[] theBytes = new byte[dis.available()];
        dis.read(theBytes, 0, dis.available());
        dis.close();
        return theBytes;
    } catch (IOException ex) {
    }
    return null;
} // ()

Why do you need to encrypt the database? The user could easily disassemble your program and figure out the key. If you're encrypting it for network transfer, then consider using PGP instead of squeezing an encryption layer into a database layer.

For Each is much faster than for I=1 to X, for some reason. Just try to go through the same dictionary,

once with for each Dkey in dDict,

and once with for Dkey = lbound(dDict.keys) to ubound(dDict.keys)

=>You will notice a huge difference, even though you are going through the same construct.

On most systems, you'd have to be trying fairly hard not to find '<stdio.h>', to the point where the first reaction is "is <stdio.h> installed". So, I'd be looking to see if the file exists in a plausible location. If not, then your installation of Turbo C is broken; reinstall. If you can find it, then you will have to establish why the compiler is not searching for it in the right place - what are the compiler options you've specified and where is the compiler searching for its headers (and why isn't it searching where the header is).

I guess you have overridden the builtin function/variable or something else "module" by setting the global variable "module". just print the module see whats in it.

Let me offer a more extensive answer considering things that you haven't mentioned as yet but will find useful.

For your current problem the answer is

$("div[id^='editDialog']");

The caret (^) is taken from regular expressions and means starts with.

Solution 1

// Select elems where 'attribute' ends with 'Dialog'
$("[attribute$='Dialog']"); 

// Selects all divs where attribute is NOT equal to value    
$("div[attribute!='value']"); 

// Select all elements that have an attribute whose value is like
$("[attribute*='value']"); 

// Select all elements that have an attribute whose value has the word foobar
$("[attribute~='foobar']"); 

// Select all elements that have an attribute whose value starts with 'foo' and ends
//  with 'bar'
$("[attribute^='foo'][attribute$='bar']");

attribute in the code above can be changed to any attribute that an element may have, such as href, name, id or src.

Solution 2

Use classes

// Matches all items that have the class 'classname'
$(".className");

// Matches all divs that have the class 'classname'
$("div.className");

Solution 3

List them (also noted in previous answers)

$("#id1,#id2,#id3");

Solution 4

For when you improve, regular expression (Never actually used these, solution one has always been sufficient, but you never know!

// Matches all elements whose id takes the form editDialog-{one_or_more_integers}
$('div').filter(function () {this.id.match(/editDialog\-\d+/)});

External return type declaration to use with multiple functions:

type ValidationReturnType = string | boolean;

function isEqual(number1: number, number2: number): ValidationReturnType {
    return number1 == number2 ? true : 'Numbers are not equal.';
}

The solution is to add height:100%; to all the parent elements of your .wrapper-div as well. So:

html{
    height: 100%;
}

body{ 
    margin:0;
    padding:0;
    overflow:hidden;
    height:100%;
}

#container{
    width:1000px;
    margin:0 auto;
    height:100%;
}

Use not, for example:

return not myval

The arguments that you provide to a bashscript will appear in the variables $1 and $2 and $3 where the number refers to the argument. $0 is the command itself.

The arguments are seperated by spaces, so if you would provide the -from and -to in the command, they will end up in these variables too, so for this:

./ocrscript.sh -from /home/kristoffer/test.png -to /home/kristoffer/test.txt

You'll get:

$0    # ocrscript.sh
$1    # -from
$2    # /home/kristoffer/test.png
$3    # -to
$4    # /home/kristoffer/test.txt

It might be easier to omit the -from and the -to, like:

ocrscript.sh /home/kristoffer/test.png /home/kristoffer/test.txt

Then you'll have:

$1    # /home/kristoffer/test.png
$2    # /home/kristoffer/test.txt

The downside is that you'll have to supply it in the right order. There are libraries that can make it easier to parse named arguments on the command line, but usually for simple shell scripts you should just use the easy way, if it's no problem.

Then you can do:

/usr/local/bin/abbyyocr9 -rl Swedish -if "$1" -of "$2" 2>&1

The double quotes around the $1 and the $2 are not always necessary but are adviced, because some strings won't work if you don't put them between double quotes.

$('a').removeAttr('href')

or

$('a').click(function(){ return false})

It depends on situation

MVC is just a general design pattern that, in the context of lean web app development, makes it easy for the developer to keep the HTML markup in an app’s presentation layer (the view) separate from the methods that receive and handle client requests (the controllers) and the data representations that are returned within the view (the models). It’s all about separation of concerns, that is, keeping code that serves one functional purpose (e.g. handling client requests) sequestered from code that serves an entirely different functional purpose (e.g. representing data).

It’s the same principle for why anybody who’s spent more than 5 min trying to build a website can appreciate the need to keep your HTML markup, JavaScript, and CSS in separate files: If you just dump all of your code into a single file, you end up with spaghetti that’s virtually un-editable later on.

Since you asked for possible "cons": I’m no authority on software architecture design, but based on my experience developing in MVC, I think it’s also important to point out that following a strict, no-frills MVC design pattern is most useful for 1) lightweight web apps, or 2) as the UI layer of a larger enterprise app. I’m surprised this specification isn’t talked about more, because MVC contains no explicit definitions for your business logic, domain models, or really anything in the data access layer of your app. When I started developing in ASP.NET MVC (i.e. before I knew other software architectures even existed), I would end up with very bloated controllers or even view models chock full of business logic that, had I been working on enterprise applications, would have made it difficult for other devs who were unfamiliar with my code to modify (i.e. more spaghetti).

this is a sample case, which will make sense I believe!

node('master'){
    stage('stage1'){
    def commit = sh (returnStdout: true, script: '''echo hi
    echo bye | grep -o "e"
    date
    echo lol''').split()


    echo "${commit[-1]} "

    }
}

You can get this with .BuiltInDocmementProperties.

For example:

Public Sub PrintDocumentProperties()
    Dim oApp As New Excel.Application
    Dim oWB As Workbook
    Set oWB = ActiveWorkbook

    Dim title As String
    title = oWB.BuiltinDocumentProperties("Title")

    Dim lastauthor As String
    lastauthor = oWB.BuiltinDocumentProperties("Last Author")

    Debug.Print title
    Debug.Print lastauthor
End Sub

See this page for all the fields you can access with this: http://msdn.microsoft.com/en-us/library/bb220896.aspx

If you're trying to do this outside of the client (i.e. with Excel closed and running code from, say, a .NET program), you need to use DSOFile.dll.

I find std::getline() is often the simplest. The optional delimiter parameter means it's not just for reading "lines":

#include <sstream>
#include <iostream>
#include <vector>

using namespace std;

int main() {
    vector<string> strings;
    istringstream f("denmark;sweden;india;us");
    string s;    
    while (getline(f, s, ';')) {
        cout << s << endl;
        strings.push_back(s);
    }
}

If you already have web.xml under /src/main/webapp/WEB-INF but you still get error "web.xml is missing and is set to true", you could check if you have included /src/main/webapp in your project source.

Here are the steps you can follow:

1. You can check this by right clicking your project, and open its Properties dialogue, and then "Deployment Assembly", where you can add Folder /src/main/webapp. Save the setting, and then,
2. Go to Eclipse menu Project -> Clean... and clean the project, and the error should go away.

(I verified this with Eclipse Mars)

Even if this is already answered (1 year ago) you could also let the fields be calculated automatically.

The HTML

    <tr>
        <td><input type="text" value="" ></td>
        <td><input type="text" class="class_name" placeholder="bla bla"/></td>
    </tr>
    <tr>
        <td><input type="text" value="" ></td>
        <td><input type="text" class="class_name" placeholder="bla bla."/></td>
    </tr>

The script

$(document).ready(function(){
                $(".class_name").each(function(){
                    $(this).keyup(function(){
                        calculateSum()
                        ;})
                    ;})
                ;}
                );
            function calculateSum(){
                var sum=0;
                $(".class_name").each(function(){
                    if(!isNaN(this.value) && this.value.length!=0){
                        sum+=parseFloat(this.value);
                    }
                    else if(isNaN(this.value)) {
                        alert("Maybe an alert if they type , instead of .");
                    }
                }
                );
                $("#sum").html(sum.toFixed(2));
                } 

There are two limits, both not enforced by C++ but rather by the hardware.

The first limit (should never be reached) is set by the restrictions of the size type used to describe an index in the array (and the size thereof). It is given by the maximum value the system's std::size_t can take. This data type is large enough to contain the size in bytes of any object

The other limit is a physical memory limit. The larger your objects in the array are, the sooner this limit is reached because memory is full. For example, a vector<int> of a given size n typically takes multiple times as much memory as an array of type vector<char> (minus a small constant value), since int is usually bigger than char. Therefore, a vector<char> may contain more items than a vector<int> before memory is full. The same counts for raw C-style arrays like int[] and char[].

Additionally, this upper limit may be influenced by the type of allocator used to construct the vector because an allocator is free to manage memory any way it wants. A very odd but nontheless conceivable allocator could pool memory in such a way that identical instances of an object share resources. This way, you could insert a lot of identical objects into a container that would otherwise use up all the available memory.

Apart from that, C++ doesn't enforce any limits.

I am a fan of SpamSpan - it is obfuscated, but still decipherable if JS is disabled. It seems to work too, although I've only been using it for about a year on a low-traffic website.

There is also a module for Drupal to automatically turn emails into SpamSpans, if you need one.

The top-rated answer with NVL is totally valid. If you have any interest in making your SQL code more portable, you might want to use CASE, which is supported with the same syntax in both Oracle and SQL Server:

select 
  type,craft,

Sure You can. I'd say that You should.

First add an Enrty and Category class:

public class Entry {     public string Id { get; set; }     public string Title { get; set; }     public string Updated { get; set; }     public string Summary { get; set; }     public string GPoint { get; set; }     public string GElev { get; set; }     public List<string> Categories { get; set; } }  public class Category {     public string Label { get; set; }     public string Term { get; set; } } 

Then use LINQ to XML

XDocument xDoc = XDocument.Load("path");          List<Entry> entries = (from x in xDoc.Descendants("entry")             select new Entry()             {                 Id = (string) x.Element("id"),                 Title = (string)x.Element("title"),                 Updated = (string)x.Element("updated"),                 Summary = (string)x.Element("summary"),                 GPoint = (string)x.Element("georss:point"),                 GElev = (string)x.Element("georss:elev"),                 Categories = (from c in x.Elements("category")                                   select new Category                                   {                                       Label = (string)c.Attribute("label"),                                       Term = (string)c.Attribute("term")                                   }).ToList();             }).ToList(); 

While others may have better methods, I was able to use $rootScope in my controllers, as each of my views/templates has a distinct controller. You will need to inject the $rootScope in each controller. While this may not be ideal, it is functioning for me, so I thought I should pass it along. If you inspect the page, it adds the ng-binding to the title tag.

Example Controller:

myapp.controller('loginPage', ['$scope', '$rootScope', function ($scope, $rootScope) {

// Dynamic Page Title and Description
$rootScope.pageTitle = 'Login to Vote';
$rootScope.pageDescription = 'This page requires you to login';
}]);

Example Index.html header:

<meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=no" />
<meta name="description" content="{{pageDescription}}">
<meta name="author" content="">
<link rel="shortcut icon" href="../../assets/ico/favicon.ico">
<base href="/">
<title>{{pageTitle}}</title>

You can also set the pageTitle and pageDescription to dynamic values, such as returning data from a REST call:

    $scope.article = restCallSingleArticle.get({ articleID: $routeParams.articleID }, function() {
    // Dynamic Page Title and Description
    $rootScope.pageTitle = $scope.article.articletitle;
    $rootScope.pageDescription = $scope.article.articledescription;
});

Again, others may have better ideas on how to approach this, but since I am using a pre-rendering, my needs are being met.

For Swift 4.+

extension UIView {
     public func removeAllSubViews() {
          self.subviews.forEach({ $0.removeFromSuperview() })

}

i hope this is use full for you.

The answer for git branch -r --contains <commit> works well for normal remote branches, but if the commit is only in the hidden head namespace that GitHub creates for PRs, you'll need a few more steps.

Say, if PR #42 was from deleted branch and that PR thread has the only reference to the commit on the repo, git branch -r doesn't know about PR #42 because refs like refs/pull/42/head aren't listed as a remote branch by default.

In .git/config for the [remote "origin"] section add a new line:

fetch = +refs/pull/*/head:refs/remotes/origin/pr/*

(This gist has more context.)

Then when you git fetch you'll get all the PR branches, and when you run git branch -r --contains <commit> you'll see origin/pr/42 contains the commit.

just use style attribute with height and width option

<input type="submit" id="search" value="Search"  style="height:50px; width:50px" />

u can do lik

var config = {
    // TODO: Add common Configuration
    module: {},
};

var x= Object.assign({}, config, {
    name: "x",
    entry: "./public/x/js/x.js",
    output: {
       path: __dirname+"/public/x/jsbuild",
       filename: "xbundle.js"
    },
});
var y= Object.assign({}, config, {
    name: "y",
    entry: "./public/y/js/FBRscript.js",
    output: {
       path: __dirname+"/public/fbr/jsbuild",
       filename: "ybundle.js"
    },
});

let list=[x,y];

for(item of list){
    module.exports =item;
}

You can use git branch --list to list the eligible branches, and use git branch -D/-d to remove the eligible branches.

One liner example:

git branch -d `git branch --list '3.2.*'`

If you are still getting an error that says "Default Activity not found" when you try to edit the run configurations even after executing:

Invalidate cache and Restart.

Then try deleting the Settings/Preferences folder:

/< USER_HOME_DIR >/.AndroidStudioPreview3.2

or on Mac :

/Users/<USER_NAME>/Library/Preferences/.AndroidStudioPreview3.2

Take each character as an amplitude and perform a discrete Fourier transform on them. If they differ only by rotation, the frequency spectra will be the same to within rounding error. Of course this is inefficient unless the length is a power of 2 so you can do an FFT :-)

The interviewers are barking up an odd tree. For languages like C# and Java, there is a difference, but in other languages like C++ there is not. OO theory doesn't differentiate the two, merely the syntax of language.

An abstract class is a class with both implementation and interface (pure virtual methods) that will be inherited. Interfaces generally do not have any implementation but only pure virtual functions.

In C# or Java an abstract class without any implementation differs from an interface only in the syntax used to inherit from it and the fact you can only inherit from one.

Another approach to this is to use my service, http://ipinfo.io, which returns the city, region and country name based on the user's current IP address. Here's a simple example:

$.get("http://ipinfo.io", function(response) {
    console.log(response.city, response.country);
}, "jsonp");

Here's a more detailed JSFiddle example that also prints out the full response information, so you can see all of the available details: http://jsfiddle.net/zK5FN/2/

getline is storing the entire line at once, which is not what you want. A simple fix is to have three variables and use cin to get them all. C++ will parse automatically at the spaces.

#include <iostream>
using namespace std;

int main() {
    string a, b, c;
    cin >> a >> b >> c;
    //now you have your three words
    return 0;
}

I don't know what particular "operation" you're talking about, so I can't help you there, but if it's changing characters, read up on string and indices. The C++ documentation is great. As for using namespace std; versus std:: and other libraries, there's already been a lot said. Try these questions on StackOverflow to start.

If you need the hash parameters present in the URL, window.location.href may be a better choice.

window.location.pathname
=> /search

window.location.href 
 => www.website.com/search#race_type=1

I realise this is a little late but you could add the following to your code. This won't work for transparent pngs though, you'd need a cropping mask for that. Which I'm now going to see about.

outerLink {
    overflow: hidden;
    position: relative;
}

outerLink:hover:after {
    background: #000;
    content: "";
    display: block;
    height: 100%;
    left: 0;
    opacity: 0.5;
    position: absolute;
    top: 0;
    width: 100%;
}

Apply this if you use laravel.

Laravel has a not_regex where field under validation must not match the given regular expression; uses the PHP preg_match function internally.

'email' => 'not_regex:/^.+$/i'

I'm creating html5 mobile apps and I noticed that the idle, bounds_changed and tilesloaded events fire when the map object is created and rendered (even if it is not visible).

To make my map run code when it is shown for the first time I did the following:

google.maps.event.addListenerOnce(map, 'tilesloaded', function(){
    //this part runs when the mapobject is created and rendered
    google.maps.event.addListenerOnce(map, 'tilesloaded', function(){
        //this part runs when the mapobject shown for the first time
    });
});

A comparison between a number and a string use to be false, so, cast you selected value to a string within ngOnInit and it will work.

I had same issue, I filled the mat-select with an enum, using

Object.keys(MyAwesomeEnum).filter(k => !isNaN(Number(k)));

and I had the enum value I wanted to select...

I spent few hours struggling my mind trying to identify why it wasn't working. And I did it just after rendering all the variables being used in the mat-select, the keys collection and the selected... if you have ["0","1","2"] and you want to select 1 (which is a number) 1=="1" is false and because of that nothing is selected.

so, the solution is to cast you selected value to a string within ngOnInit and it will work.

You may use line-height on div1 as below:

<div id="div1" style="line-height:0px;">
    <div></div><div></div><div></div><br/><div></div><div></div><div></div>
</div>

See this: http://jsfiddle.net/wCpU8/

If you want to store a python dict in redis, it is better to store it as json string.

import redis

r = redis.StrictRedis(host='localhost', port=6379, db=0)
mydict = { 'var1' : 5, 'var2' : 9, 'var3': [1, 5, 9] }
rval = json.dumps(mydict)
r.set('key1', rval)

While retrieving de-serialize it using json.loads

data = r.get('key1')
result = json.loads(data)
arr = result['var3']

What about types (eg.bytes) that are not serialized by json functions ?

You can write encoder/decoder functions for types that cannot be serialized by json functions. eg. writing base64/ascii encoder/decoder function for byte array.

This is what I'm teaching my students tomorrow. After years of looking at this stuff... ie all of the documentation above http://www.cpearson.com/excel/errorhandling.htm comes to mind as an excellent one...

I hope this summarizes it for others. There is an Err object and an active (or inactive) ErrorHandler. Both need to be handled and reset for new errors.

Paste this into a workbook and step through it with F8.

Sub ErrorHandlingDemonstration()

    On Error GoTo ErrorHandler

    'this will error
    Debug.Print (1 / 0)

    'this will also error
    dummy = Application.WorksheetFunction.VLookup("not gonna find me", Range("A1:B2"), 2, True)

    'silly error
    Dummy2 = "string" * 50

    Exit Sub

zeroDivisionErrorBlock:
    maybeWe = "did some cleanup on variables that shouldnt have been divided!"
    ' moves the code execution to the line AFTER the one that errored
    Resume Next

vlookupFailedErrorBlock:
    maybeThisTime = "we made sure the value we were looking for was in the range!"
    ' moves the code execution to the line AFTER the one that errored
    Resume Next

catchAllUnhandledErrors:
    MsgBox(thisErrorsDescription)
    Exit Sub

ErrorHandler:
    thisErrorsNumberBeforeReset = Err.Number
    thisErrorsDescription = Err.Description
    'this will reset the error object and error handling
    On Error GoTo 0
    'this will tell vba where to go for new errors, ie the new ErrorHandler that was previous just reset!
    On Error GoTo ErrorHandler

    ' 11 is the err.number for division by 0
    If thisErrorsNumberBeforeReset = 11 Then
        GoTo zeroDivisionErrorBlock
    ' 1004 is the err.number for vlookup failing
    ElseIf thisErrorsNumberBeforeReset = 1004 Then
        GoTo vlookupFailedErrorBlock
    Else
        GoTo catchAllUnhandledErrors
    End If

End Sub

I had a similar problem trying to POST to MailGun for some automated emails I was implementing in an app.

I was able to get this working properly with a large HTTP response. I put the full path into Keys.plist so that I can upload my code to github and broke out some of the arguments into variables so I can have them programmatically set later down the road.

// Email the FBO with desired information
// Parse our Keys.plist so we can use our path
var keys: NSDictionary?

if let path = NSBundle.mainBundle().pathForResource("Keys", ofType: "plist") {
    keys = NSDictionary(contentsOfFile: path)
}

if let dict = keys {
    // variablize our https path with API key, recipient and message text
    let mailgunAPIPath = dict["mailgunAPIPath"] as? String
    let emailRecipient = "[email protected]"
    let emailMessage = "Testing%20email%20sender%20variables"

    // Create a session and fill it with our request
    let session = NSURLSession.sharedSession()
    let request = NSMutableURLRequest(URL: NSURL(string: mailgunAPIPath! + "from=FBOGo%20Reservation%20%3Cscheduler@<my domain>.com%3E&to=reservations@<my domain>.com&to=\(emailRecipient)&subject=A%20New%20Reservation%21&text=\(emailMessage)")!)

    // POST and report back with any errors and response codes
    request.HTTPMethod = "POST"
    let task = session.dataTaskWithRequest(request, completionHandler: {(data, response, error) in
        if let error = error {
            print(error)
        }

        if let response = response {
            print("url = \(response.URL!)")
            print("response = \(response)")
            let httpResponse = response as! NSHTTPURLResponse
            print("response code = \(httpResponse.statusCode)")
        }
    })
    task.resume()
}

The Mailgun Path is in Keys.plist as a string called mailgunAPIPath with the value:

https://API:key-<my key>@api.mailgun.net/v3/<my domain>.com/messages?

Hope this helps offers a solution to someone trying to avoid using 3rd party code for their POST requests!

The Newline in T-SQL is represented by CHAR(13) & CHAR(10) (Carriage return + Line Feed). Accordingly, you can create a REPLACE statement with the text you want to replace the newline with.

REPLACE(MyField, CHAR(13) + CHAR(10), 'something else')

In Eclipse, right click on the xsd file you want to get --> Generate --> Java... --> Generator: "Schema to JAXB Java Classes".

Use ngInit: https://docs.angularjs.org/api/ng/directive/ngInit

You just declared a jagged array. Such kind of arrays can have different sizes for all dimensions. For example:

string[][] jaggedStrings =  {
new string[] {"x","y","z"},
new string[] {"x","y"},
new string[] {"x"}
};

In your case you need regular array. See answers above. More about jagged arrays

You might want to start by learning what Javascript and php are. Javascript is a client side script language running in the browser of the machine of the client connected to the webserver on which php runs. These languages can not communicate directly.

Depending on your goal you'll need to issue an AJAX get or post request to the server and return a json/xml/html/whatever response you need and inject the result back in the DOM structure of the site. I suggest Jquery, BackboneJS or any other JS framework for this. See the Jquery documentation for examples.

If you have to pass php data to JS on the same site you can echo the data as JS and turn your php data using json_encode() into JS.

<script type="text/javascript>
    var foo = <?php echo json_encode($somePhpVar); ?>
</script>

For the form, use:

<form name="form1" action="<?=$_SERVER['PHP_SELF'];?>" method="get">

and for getting the value, use the get method as follows:

$value = $_GET['name_to_send_using_get'];

Instead of using doubles for decimal arithemetic, please use java.math.BigDecimal. It would produce the expected results.

For reference take a look at this stackoverflow question

My solution was extremely close to Joel's (Not Etherton, just plain Joel):

public partial class WaitingDialog : Form
{
    public WaitingDialog()
    {
        InitializeComponent();

        SetStyle(ControlStyles.SupportsTransparentBackColor, true);
        this.BackColor = Color.Transparent;
        this.TransparencyKey = Color.Transparent; // I had to add this to get it to work.

        // Other stuff
    }

    protected override void OnPaintBackground(PaintEventArgs e) { /* Ignore */ }
}

You can create a custom object with the criteria and the function corresponding to the criteria

var rules = [{ lowerLimit: 0,    upperLimit: 1000, action: function1 }, 
             { lowerLimit: 1000, upperLimit: 2000, action: function2 }, 
             { lowerLimit: 2000, upperLimit: 3000, action: function3 }];

Define functions for what you want to do in these cases (define function1, function2 etc)

And "evaluate" the rules

function applyRules(scrollLeft)
{
   for(var i=0; i>rules.length; i++)
   {
       var oneRule = rules[i];
       if(scrollLeft > oneRule.lowerLimit && scrollLeft < oneRule.upperLimit)
       {
          oneRule.action();
       }
   }
}

Note

I hate using 30 if statements

Many times if statements are easier to read and maintain. I would recommend the above only when you have a lot of conditions and a possibility of lot of growth in the future.

Update
As @Brad pointed out in the comments, if the conditions are mutually exclusive (only one of them can be true at a time), checking the upper limit should be sufficient:

if(scrollLeft < oneRule.upperLimit)

provided that the conditions are defined in ascending order (first the lowest one, 0 to 1000, and then 1000 to 2000 for example)

If you really want to create an array rather than a list use either

String[] names = ["lucas", "Fred", "Mary"]

or

def names = ["lucas", "Fred", "Mary"].toArray()

puts `date`
puts $?

An example I recently fixed is creating new GC and Image objects, but forgetting to call dispose() method.

GC javadoc snippet:

Application code must explicitly invoke the GC.dispose() method to release the operating system resources managed by each instance when those instances are no longer required. This is particularly important on Windows95 and Windows98 where the operating system has a limited number of device contexts available.

Image javadoc snippet:

Application code must explicitly invoke the Image.dispose() method to release the operating system resources managed by each instance when those instances are no longer required.

setInterval(function() {
    updatechat();
}, 2000);

function updatechat() {
    alert('hello world');
}

I used Robert Lee`s answer and it works great! Just writing down the complete function i'm using:

function isMobileDevice(){
    $aMobileUA = array(
        '/iphone/i' => 'iPhone', 
        '/ipod/i' => 'iPod', 
        '/ipad/i' => 'iPad', 
        '/android/i' => 'Android', 
        '/blackberry/i' => 'BlackBerry', 
        '/webos/i' => 'Mobile'
    );

    //Return true if Mobile User Agent is detected
    foreach($aMobileUA as $sMobileKey => $sMobileOS){
        if(preg_match($sMobileKey, $_SERVER['HTTP_USER_AGENT'])){
            return true;
        }
    }
    //Otherwise return false..  
    return false;
}

You have to send a DELETE request to

http://[your_host]:9200/[your_index_name_here]

You can also delete a single document:

http://[your_host]:9200/[your_index_name_here]/[your_type_here]/[your_doc_id]

I suggest you to use elastichammer.

After deleting you can look up if the index still exists with the following URL: http://[your_host]:9200/_stats/

Good luck!

def fun():
    print(('{0} Here is a really long '
           'sentence with {1}').format(3, 5))

Adjacent string literals are concatenated at compile time, just as in C. http://docs.python.org/reference/lexical_analysis.html#string-literal-concatenation is a good place to start for more info.

If you're using Bash, you don't even have to use grep:

files="*.jpg"
regex="[0-9]+_([a-z]+)_[0-9a-z]*"
for f in $files    # unquoted in order to allow the glob to expand
do
    if [[ $f =~ $regex ]]
    then
        name="${BASH_REMATCH[1]}"
        echo "${name}.jpg"    # concatenate strings
        name="${name}.jpg"    # same thing stored in a variable
    else
        echo "$f doesn't match" >&2 # this could get noisy if there are a lot of non-matching files
    fi
done

It's better to put the regex in a variable. Some patterns won't work if included literally.

This uses =~ which is Bash's regex match operator. The results of the match are saved to an array called $BASH_REMATCH. The first capture group is stored in index 1, the second (if any) in index 2, etc. Index zero is the full match.

You should be aware that without anchors, this regex (and the one using grep) will match any of the following examples and more, which may not be what you're looking for:

123_abc_d4e5
xyz123_abc_d4e5
123_abc_d4e5.xyz
xyz123_abc_d4e5.xyz

To eliminate the second and fourth examples, make your regex like this:

^[0-9]+_([a-z]+)_[0-9a-z]*

which says the string must start with one or more digits. The carat represents the beginning of the string. If you add a dollar sign at the end of the regex, like this:

^[0-9]+_([a-z]+)_[0-9a-z]*$

then the third example will also be eliminated since the dot is not among the characters in the regex and the dollar sign represents the end of the string. Note that the fourth example fails this match as well.

If you have GNU grep (around 2.5 or later, I think, when the \K operator was added):

name=$(echo "$f" | grep -Po '(?i)[0-9]+_\K[a-z]+(?=_[0-9a-z]*)').jpg

The \K operator (variable-length look-behind) causes the preceding pattern to match, but doesn't include the match in the result. The fixed-length equivalent is (?<=) - the pattern would be included before the closing parenthesis. You must use \K if quantifiers may match strings of different lengths (e.g. +, *, {2,4}).

The (?=) operator matches fixed or variable-length patterns and is called "look-ahead". It also does not include the matched string in the result.

In order to make the match case-insensitive, the (?i) operator is used. It affects the patterns that follow it so its position is significant.

The regex might need to be adjusted depending on whether there are other characters in the filename. You'll note that in this case, I show an example of concatenating a string at the same time that the substring is captured.

I don't think that there are any neat tricks you can do storing this as you can do for example with an MD5 hash.

I think your best bet is to store it as a CHAR(60) as it is always 60 chars long

nc -l 8000

Where 8000 is the port number. If the port is free, it will start a server that you can close easily. If it isn't it will throw an error:

nc: Address already in use

myCars.Select((v, i) => new {car = v, index = i}).First(myCondition).index;

or the slightly shorter

myCars.Select((car, index) => new {car, index}).First(myCondition).index;

Use ResponseEntity instead of ResponseBody. This way you have access to the response headers and you can set the appropiate content type. According to the Spring docs:

The HttpEntity is similar to @RequestBody and @ResponseBody. Besides getting access to the request and response body, HttpEntity (and the response-specific subclass ResponseEntity) also allows access to the request and response headers

The code will look like:

@RequestMapping(method=RequestMethod.GET, value="/fooBar")
public ResponseEntity<String> fooBar2() {
    String json = "jsonResponse";
    HttpHeaders responseHeaders = new HttpHeaders();
    responseHeaders.setContentType(MediaType.APPLICATION_JSON);
    return new ResponseEntity<String>(json, responseHeaders, HttpStatus.CREATED);
}

This can also help you by showing full details of the error on a client's browser.

<system.web>
    <customErrors mode="Off"/>
</system.web>
<system.webServer>
    <httpErrors errorMode="Detailed" />
</system.webServer>

for me works this two commands:

git checkout commit_id
git push origin +name_of_branch

I suggest Junidecode . It will handle not only 'L' and 'Ø', but it also works well for transcribing from other alphabets, such as Chinese, into Latin alphabet.

almost the same thing as David G's answer but without the anonymous function, if you don't feel like including one.

s = s.substr(0, s.indexOf(',') === -1 ? s.length : s.indexOf(','));

in this case we make use of the fact that the second argument of substr is a length, and that we know our substring is starting at 0.

the top answer is not a generic solution because of the undesirable behavior if the string doesn't contain the character you are looking for.

if you want correct behavior in a generic case, use this method or David G's method, not the top answer

regex and split methods will also work, but may be somewhat slower / overkill for this specific problem.

You need access to the object.... you can't simply ask the form class....

eg...

you would of done some thing like

Form1.txtLog.Text = "blah"

instead of

Form1 blah = new Form1();
blah.txtLog.Text = "hello"

I think this will do what you want:

DateTime d1 = DateTime.Now;
DateTime d2 = DateTime.Now.AddDays(-1);

TimeSpan t = d1 - d2;
double NrOfDays = t.TotalDays;

I know this is an old question, but maybe I can be of help to someone, bc this also stumped me until I read the documentation a bit more:

prevArrow string (html|jQuery selector) | object (DOM node|jQuery object) Previous Allows you to select a node or customize the HTML for the "Previous" arrow.

nextArrow string (html|jQuery selector) | object (DOM node|jQuery object) Next Allows you to select a node or customize the HTML for the "Next" arrow.

this is how i changed my buttons.. worked perfectly.

  $('.carousel-content').slick({
      prevArrow:"<img class='a-left control-c prev slick-prev' src='../images/shoe_story/arrow-left.png'>",
      nextArrow:"<img class='a-right control-c next slick-next' src='../images/shoe_story/arrow-right.png'>"
  });

I asked a 4-year-old to solve this problem. He sorted the numbers and then counted along. This has a space requirement of O(kitchen floor), and it works just as easy however many balls are missing.

Disclaimer

2014-12-01 Update: The answer below works only for one very specific format of CSV. As correctly pointed out by DG in the comments, this solution does not fit the RFC 4180 definition of CSV and it also does not fit Microsoft Excel format. This solution simply demonstrates how one can parse one (non-standard) CSV line of input which contains a mix of string types, where the strings may contain escaped quotes and commas.

A non-standard CSV solution

As austincheney correctly points out, you really need to parse the string from start to finish if you wish to properly handle quoted strings that may contain escaped characters. Also, the OP does not clearly define what a "CSV string" really is. First we must define what constitutes a valid CSV string and its individual values.

Given: "CSV String" Definition

For the purpose of this discussion, a "CSV string" consists of zero or more values, where multiple values are separated by a comma. Each value may consist of:

1. A double quoted string (may contain unescaped single quotes).
2. A single quoted string (may contain unescaped double quotes).
3. A non-quoted string (may not contain quotes, commas or backslashes).
4. An empty value. (An all whitespace value is considered empty.)

Rules/Notes:

• Quoted values may contain commas.
• Quoted values may contain escaped-anything, e.g. 'that\'s cool'.
• Values containing quotes, commas, or backslashes must be quoted.
• Values containing leading or trailing whitespace must be quoted.
• The backslash is removed from all: \' in single quoted values.
• The backslash is removed from all: \" in double quoted values.
• Non-quoted strings are trimmed of any leading and trailing spaces.
• The comma separator may have adjacent whitespace (which is ignored).

Find:

A JavaScript function which converts a valid CSV string (as defined above) into an array of string values.

Solution:

The regular expressions used by this solution are complex. And (IMHO) all non-trivial regular expressions should be presented in free-spacing mode with lots of comments and indentation. Unfortunately, JavaScript does not allow free-spacing mode. Thus, the regular expressions implemented by this solution are first presented in native regular expressions syntax (expressed using Python's handy r'''...''' raw-multi-line-string syntax).

First here is a regular expression which validates that a CVS string meets the above requirements:

Regular expression to validate a "CSV string":

re_valid = r"""
# Validate a CSV string having single, double or un-quoted values.
^                                   # Anchor to start of string.
\s*                                 # Allow whitespace before value.
(?:                                 # Group for value alternatives.
  '[^'\\]*(?:\\[\S\s][^'\\]*)*'     # Either Single quoted string,
| "[^"\\]*(?:\\[\S\s][^"\\]*)*"     # or Double quoted string,
| [^,'"\s\\]*(?:\s+[^,'"\s\\]+)*    # or Non-comma, non-quote stuff.
)                                   # End group of value alternatives.
\s*                                 # Allow whitespace after value.
(?:                                 # Zero or more additional values
  ,                                 # Values separated by a comma.
  \s*                               # Allow whitespace before value.

  )                                 # End group of value alternatives.
  \s*                               # Allow whitespace after value.
)*                                  # Zero or more additional values
$                                   # Anchor to end of string.
"""

If a string matches the above regular expression, then that string is a valid CSV string (according to the rules previously stated) and may be parsed using the following regular expression. The following regular expression is then used to match one value from the CSV string. It is applied repeatedly until no more matches are found (and all values have been parsed).

Regular expression to parse one value from a valid CSV string:

re_value = r"""
# Match one value in valid CSV string.
(?!\s*$)                            # Don't match empty last value.
\s*                                 # Strip whitespace before value.
(?:                                 # Group for value alternatives.
  '([^'\\]*(?:\\[\S\s][^'\\]*)*)'   # Either $1: Single quoted string,
| "([^"\\]*(?:\\[\S\s][^"\\]*)*)"   # or $2: Double quoted string,
| ([^,'"\s\\]*(?:\s+[^,'"\s\\]+)*)  # or $3: Non-comma, non-quote stuff.
)                                   # End group of value alternatives.
\s*                                 # Strip whitespace after value.
(?:,|$)                             # Field ends on comma or EOS.
"""

Note that there is one special case value that this regular expression does not match - the very last value when that value is empty. This special "empty last value" case is tested for and handled by the JavaScript function which follows.

JavaScript function to parse CSV string:

// Return array of string values, or NULL if CSV string not well formed.
function CSVtoArray(text) {
    var re_valid = /^\s*(?:'[^'\\]*(?:\\[\S\s][^'\\]*)*'|"[^"\\]*(?:\\[\S\s][^"\\]*)*"|[^,'"\s\\]*(?:\s+[^,'"\s\\]+)*)\s*(?:,\s*(?:'[^'\\]*(?:\\[\S\s][^'\\]*)*'|"[^"\\]*(?:\\[\S\s][^"\\]*)*"|[^,'"\s\\]*(?:\s+[^,'"\s\\]+)*)\s*)*$/;
    var re_value = /(?!\s*$)\s*(?:'([^'\\]*(?:\\[\S\s][^'\\]*)*)'|"([^"\\]*(?:\\[\S\s][^"\\]*)*)"|([^,'"\s\\]*(?:\s+[^,'"\s\\]+)*))\s*(?:,|$)/g;

    // Return NULL if input string is not well formed CSV string.
    if (!re_valid.test(text)) return null;

    var a = []; // Initialize array to receive values.
    text.replace(re_value, // "Walk" the string using replace with callback.
        function(m0, m1, m2, m3) {

            // Remove backslash from \' in single quoted values.
            if (m1 !== undefined) a.push(m1.replace(/\\'/g, "'"));

            // Remove backslash from \" in double quoted values.
            else if (m2 !== undefined) a.push(m2.replace(/\\"/g, '"'));
            else if (m3 !== undefined) a.push(m3);
            return ''; // Return empty string.
        });

    // Handle special case of empty last value.
    if (/,\s*$/.test(text)) a.push('');
    return a;
};

Example input and output:

In the following examples, curly braces are used to delimit the {result strings}. (This is to help visualize leading/trailing spaces and zero-length strings.)

// Test 1: Test string from original question.
var test = "'string, duppi, du', 23, lala";
var a = CSVtoArray(test);
/* Array has three elements:
    a[0] = {string, duppi, du}
    a[1] = {23}
    a[2] = {lala} */

// Test 2: Empty CSV string.
var test = "";
var a = CSVtoArray(test);
/* Array has zero elements: */

// Test 3: CSV string with two empty values.
var test = ",";
var a = CSVtoArray(test);
/* Array has two elements:
    a[0] = {}
    a[1] = {} */

// Test 4: Double quoted CSV string having single quoted values.
var test = "'one','two with escaped \' single quote', 'three, with, commas'";
var a = CSVtoArray(test);
/* Array has three elements:
    a[0] = {one}
    a[1] = {two with escaped ' single quote}
    a[2] = {three, with, commas} */

// Test 5: Single quoted CSV string having double quoted values.
var test = '"one","two with escaped \" double quote", "three, with, commas"';
var a = CSVtoArray(test);
/* Array has three elements:
    a[0] = {one}
    a[1] = {two with escaped " double quote}
    a[2] = {three, with, commas} */

// Test 6: CSV string with whitespace in and around empty and non-empty values.
var test = "   one  ,  'two'  ,  , ' four' ,, 'six ', ' seven ' ,  ";
var a = CSVtoArray(test);
/* Array has eight elements:
    a[0] = {one}
    a[1] = {two}
    a[2] = {}
    a[3] = { four}
    a[4] = {}
    a[5] = {six }
    a[6] = { seven }
    a[7] = {} */

Additional notes:

This solution requires that the CSV string be "valid". For example, unquoted values may not contain backslashes or quotes, e.g. the following CSV string is not valid:

var invalid1 = "one, that's me!, escaped \, comma"

This is not really a limitation because any sub-string may be represented as either a single or double quoted value. Note also that this solution represents only one possible definition for "comma-separated values".

Case 2 - where the same issue can arrise) in my case the problem was due to the following line:

<webServices>
  <protocols>
    <remove name="Documentation"/>
  </protocols>
</webServices>

It works well in server as calls are made directly to the webservice function - however will fail if you run the service directly from .Net in the debug environment and want to test running the function manually.

1.

first of all Port 80(or what ever you are using) and 443 must be allow for both TCP and UDP packets. To do this, create 2 inbound rules for TPC and UDP on Windows Firewall for port 80 and 443. (or you can disable your whole firewall for testing but permanent solution if allow inbound rule)

2.

If you are using WAMPServer 3 See bottom of answer

For WAMPServer versions <= 2.5

You need to change the security setting on Apache to allow access from anywhere else, so edit your httpd.conf file.

Change this section from :

#   onlineoffline tag - don't remove
     Order Deny,Allow
     Deny from all
     Allow from 127.0.0.1
     Allow from ::1
     Allow from localhost

To :

#   onlineoffline tag - don't remove
    Order Allow,Deny
      Allow from all

if "Allow from all" line not work for your then use "Require all granted" then it will work for you.

WAMPServer 3 has a different method

In version 3 and > of WAMPServer there is a Virtual Hosts pre defined for localhost so dont amend the httpd.conf file at all, leave it as you found it.

Using the menus, edit the httpd-vhosts.conf file.

It should look like this :

<VirtualHost *:80>
    ServerName localhost
    DocumentRoot D:/wamp/www
    <Directory  "D:/wamp/www/">
        Options +Indexes +FollowSymLinks +MultiViews
        AllowOverride All
        Require local
    </Directory>
</VirtualHost>

Amend it to

<VirtualHost *:80>
    ServerName localhost
    DocumentRoot D:/wamp/www
    <Directory  "D:/wamp/www/">
        Options +Indexes +FollowSymLinks +MultiViews
        AllowOverride All
        Require all granted
    </Directory>
</VirtualHost>

Note:if you are running wamp for other than port 80 then VirtualHost will be like VirtualHost *:86.(86 or port whatever you are using) instead of VirtualHost *:80

3. Dont forget to restart All Services of Wamp or Apache after making this change

just seperate the class name with a comma.

Use attr

$('#abc_frame').attr('src', url)

This way you can get and set every HTML tag attribute. Note that there is also .prop(). See .prop() vs .attr() about the differences. Short version: .attr() is used for attributes as they are written in HTML source code and .prop() is for all that JavaScript attached to the DOM element.

Unique key allows max 2 NULL values. Explaination:

create table teppp
(
id int identity(1,1) primary key,
name varchar(10 )unique,
addresss varchar(10)
)

insert into teppp ( name,addresss) values ('','address1')
insert into teppp ( name,addresss) values ('NULL','address2')
insert into teppp ( addresss) values ('address3')

select * from teppp
null string , address1
NULL,address2
NULL,address3

If you try inserting same values as below:

insert into teppp ( name,addresss) values ('','address4')
insert into teppp ( name,addresss) values ('NULL','address5')
insert into teppp ( addresss) values ('address6')

Every time you will get error like:

Violation of UNIQUE KEY constraint 'UQ__teppp__72E12F1B2E1BDC42'. Cannot insert duplicate key in object 'dbo.teppp'.
The statement has been terminated.

In C# when debugging threads for example, you can see each thread's ID.

This will be the Ids of the managed threads. ManagedThreadId is a member of Thread so you can get the Id from any Thread object. This will get you the current ManagedThreadID:

Thread.CurrentThread.ManagedThreadId

To get an OS thread by its OS thread ID (not ManagedThreadID), you can try a bit of linq.

int unmanagedId = 2345;
ProcessThread myThread = (from ProcessThread entry in Process.GetCurrentProcess().Threads
   where entry.Id == unmanagedId 
   select entry).First();

It seems there is no way to enumerate the managed threads and no relation between ProcessThread and Thread, so getting a managed thread by its Id is a tough one.

For more details on Managed vs Unmanaged threading, see this MSDN article.

MySQL says:

All integer types can have an optional (nonstandard) attribute UNSIGNED. Unsigned type can be used to permit only nonnegative numbers in a column or when you need a larger upper numeric range for the column. For example, if an INT column is UNSIGNED, the size of the column's range is the same but its endpoints shift from -2147483648 and 2147483647 up to 0 and 4294967295.

When do I use it ?

Ask yourself this question: Will this field ever contain a negative value?
If the answer is no, then you want an UNSIGNED data type.

A common mistake is to use a primary key that is an auto-increment INT starting at zero, yet the type is SIGNED, in that case you’ll never touch any of the negative numbers and you are reducing the range of possible id's to half.

Sadly there are no operation-assignment operators in VBA.

(Addition-assignment += are available in VB.Net)

Pointless workaround;

Sub Inc(ByRef i As Integer)
   i = i + 1

Your .mobile div has the following styles on it:

.mobile {
    display: none !important;
    visibility: hidden !important;
}

Therefore you need to override the visibility property with visible in addition to overriding the display property with block. Like so:

.visible-sm {
    display: block !important;
    visibility: visible !important;
}

Easy way to do

String[] listofIDS={"[email protected]","[email protected]"};

    message.addRecipients(Message.RecipientType.CC,InternetAddress.parse(cc));

Since aa is the set/object that might be null, can you check aa == null ?

(aa / xx might be interchangeable (a typo in the question); the original question talks about xx but only defines aa)

i.e.

select new {
    AssetID = x.AssetID,
    Status = aa == null ? (bool?)null : aa.Online; // a Nullable<bool>
}

or if you want the default to be false (not null):

select new {
    AssetID = x.AssetID,
    Status = aa == null ? false : aa.Online;
}

Update; in response to the downvote, I've investigated more... the fact is, this is the right approach! Here's an example on Northwind:

        using(var ctx = new DataClasses1DataContext())
        {
            ctx.Log = Console.Out;
            var qry = from boss in ctx.Employees
                      join grunt in ctx.Employees
                          on boss.EmployeeID equals grunt.ReportsTo into tree
                      from tmp in tree.DefaultIfEmpty()
                      select new
                             {
                                 ID = boss.EmployeeID,
                                 Name = tmp == null ? "" : tmp.FirstName
                        };
            foreach(var row in qry)
            {
                Console.WriteLine("{0}: {1}", row.ID, row.Name);
            }
        }

And here's the TSQL - pretty much what we want (it isn't ISNULL, but it is close enough):

SELECT [t0].[EmployeeID] AS [ID],
    (CASE
        WHEN [t2].[test] IS NULL THEN CONVERT(NVarChar(10),@p0)
        ELSE [t2].[FirstName]
     END) AS [Name]
FROM [dbo].[Employees] AS [t0]
LEFT OUTER JOIN (
    SELECT 1 AS [test], [t1].[FirstName], [t1].[ReportsTo]
    FROM [dbo].[Employees] AS [t1]
    ) AS [t2] ON ([t0].[EmployeeID]) = [t2].[ReportsTo]
-- @p0: Input NVarChar (Size = 0; Prec = 0; Scale = 0) []
-- Context: SqlProvider(Sql2008) Model: AttributedMetaModel Build: 3.5.30729.1

QED?

You need to multiply your Model matrix. Because that is where model position, scaling and rotation should be (that's why it's called the model matrix).

All you need to do is (see here)

Model = glm::rotate(Model, angle_in_radians, glm::vec3(x, y, z)); // where x, y, z is axis of rotation (e.g. 0 1 0)

Note that to convert from degrees to radians, use glm::radians(degrees)

That takes the Model matrix and applies rotation on top of all the operations that are already in there. The other functions translate and scale do the same. That way it's possible to combine many transformations in a single matrix.

note: earlier versions accepted angles in degrees. This is deprecated since 0.9.6

Model = glm::rotate(Model, angle_in_degrees, glm::vec3(x, y, z)); // where x, y, z is axis of rotation (e.g. 0 1 0)

Targeting all elements but html : *:not(html) caused problems on other elements in my case. It modified the stacking context, causing some z-index to break.

We should better try to target the right element and apply -webkit-transform: translate3d(0,0,0) to it only.

Edit : sometimes the translate3D(0,0,0) doesn't work, we can use the following method, targeting the right element :

@keyframes redraw{
    0% {opacity: 1;}
    100% {opacity: .99;}
}

// ios redraw fix
animation: redraw 1s linear infinite;

As others have already mentioned, HTML 4 requires the <style> tag to be placed in the <head> section (even though most browsers allow <style> tags within the body).

However, HTML 5 includes the scoped attribute (see update below), which allows you to create style sheets that are scoped within the parent element of the <style> tag. This also enables you to place <style> tags within the <body> element:

<!DOCTYPE html>
<html>
<head></head>
<body>

<div id="scoped-content">
    <style type="text/css" scoped>
        h1 { color: red; } 
    </style>

    <h1>Hello</h1>
</div>

    <h1>
      World
    </h1>

</body>
</html>

If you render the above code in an HTML-5 enabled browser that supports scoped, you will see the limited scope of the style sheet.

There's just one major caveat...

At the time I'm writing this answer (May, 2013) almost no mainstream browser currently supports the scoped attribute. (Although apparently developer builds of Chromium support it.)

HOWEVER, there is an interesting implication of the scoped attribute that pertains to this question. It means that future browsers are mandated via the standard to allow <style> elements within the <body> (as long as the <style> elements are scoped.)

So, given that:

• Almost every existing browser currently ignores the scoped attribute
• Almost every existing browser currently allows <style> tags within the <body>
• Future implementations will be required to allow (scoped) <style> tags within the <body>

...then there is literally no harm * in placing <style> tags within the body, as long as you future proof them with a scoped attribute. The only problem is that current browsers won't actually limit the scope of the stylesheet - they'll apply it to the whole document. But the point is that, for all practical purposes, you can include <style> tags within the <body> provided that you:

• Future-proof your HTML by including the scoped attribute
• Understand that as of now, the stylesheet within the <body> will not actually be scoped (because no mainstream browser support exists yet)

* except of course, for pissing off HTML validators...

Finally, regarding the common (but subjective) claim that embedding CSS within HTML is poor practice, it should be noted that the whole point of the scoped attribute is to accommodate typical modern development frameworks that allow developers to import chunks of HTML as modules or syndicated content. It is very convenient to have embedded CSS that only applies to a particular chunk of HTML, in order to develop encapsulated, modular components with specific stylings.

Update as of Feb 2019, according to the Mozilla documentation, the scoped attribute is deprecated. Chrome stopped supporting it in version 36 (2014) and Firefox in version 62 (2018). In both cases, the feature had to be explicitly enabled by the user in the browsers' settings. No other major browser ever supported it.

If you're not sure whether the object has been disposed or not, you should call the Dispose method itself rather than methods such as Close. While the framework doesn't guarantee that the Dispose method must run without exceptions even if the object had previously been disposed, it's a common pattern and to my knowledge implemented on all disposable objects in the framework.

The typical pattern for Dispose, as per Microsoft:

public void Dispose() 
{
    Dispose(true);

    // Use SupressFinalize in case a subclass
    // of this type implements a finalizer.
    GC.SuppressFinalize(this);      
}

protected virtual void Dispose(bool disposing)
{
    // If you need thread safety, use a lock around these 
    // operations, as well as in your methods that use the resource.
    if (!_disposed)
    {
        if (disposing) {
            if (_resource != null)
                _resource.Dispose();
                Console.WriteLine("Object disposed.");
        }

        // Indicate that the instance has been disposed.
        _resource = null;
        _disposed = true;   
    }
}

Notice the check on _disposed. If you were to call a Dispose method implementing this pattern, you could call Dispose as many times as you wanted without hitting exceptions.

I add those key in InfoPlist.strings in iOS 8.4, iPad mini 2. It works too. I don't set any key, like NSLocationWhenInUseUsageDescription, in my Info.plist.

InfoPlist.strings:

"NSLocationWhenInUseUsageDescription" = "I need GPS information....";

Base on this thread, it said, as in iOS 7, can be localized in the InfoPlist.strings. In my test, those keys can be configured directly in the file InfoPlist.strings.

So the first thing you need to do is to add one or both of the > following keys to your Info.plist file:

• NSLocationWhenInUseUsageDescription
• NSLocationAlwaysUsageDescription

Both of these keys take a string which is a description of why you need location services. You can enter a string like “Location is required to find out where you are” which, as in iOS 7, can be localized in the InfoPlist.strings file.

UPDATE:

I think @IOS's method is better. Add key to Info.plist with empty value and add localized strings to InfoPlist.strings.

I had the same problem, because as soon as display: x; is in animation, it won't animate.

I ended up in creating custom keyframes, first changing the display value then the other values. May give a better solution.

Or, instead of using display: none; use position: absolute; visibility: hidden; It should work.

This works for me, hacked it once to see if it is possible, but never actually used in my program (GUI is so much nicer):

import time
f = '%4i %%'
len_to_clear = len(f)+1
clear = '\x08'* len_to_clear
print 'Progress in percent:'+' '*(len_to_clear),
for i in range(123):
    print clear+f % (i*100//123),
    time.sleep(0.4)
raw_input('\nDone')

My simple solution is this

if (ContextCompat.checkSelfPermission(this, android.Manifest.permission.ACCESS_FINE_LOCATION) ==
        PackageManager.PERMISSION_GRANTED &&
        ContextCompat.checkSelfPermission(this, android.Manifest.permission.ACCESS_COARSE_LOCATION) ==
        PackageManager.PERMISSION_GRANTED) {
    googleMap.setMyLocationEnabled(true);
    googleMap.getUiSettings().setMyLocationButtonEnabled(true);
} else {
    Toast.makeText(this, R.string.error_permission_map, Toast.LENGTH_LONG).show();
}

or you can open permission dialog in else like this

} else {
   ActivityCompat.requestPermissions(this, new String[] {
      Manifest.permission.ACCESS_FINE_LOCATION, 
      Manifest.permission.ACCESS_COARSE_LOCATION }, 
      TAG_CODE_PERMISSION_LOCATION);
}

I tried casting to a string and testing for a zero-length string and it worked.

CASE 
   WHEN LEN(CAST(field_value AS VARCHAR(MAX))) = 0 THEN 
       DO THIS
END AS field 

From what I understand about your question, before passing the character into the switch statement, you can convert it to lowercase. So you don't have to worry about upper cases because they are automatically converted to lower case. For that you need to use the below function:

Character.toLowerCase(c);

According to SVG spec, alignment-baseline only applies to <tspan>, <textPath>, <tref> and <altGlyph>. My understanding is that it is used to offset those from the <text> object above them. I think what you are looking for is dominant-baseline.

Possible values of dominant-baseline are:

auto | use-script | no-change | reset-size | ideographic | alphabetic | hanging | mathematical | central | middle | text-after-edge | text-before-edge | inherit

Check the W3C recommendation for the dominant-baseline property for more information about each possible value.

I originally intentionally never learned how to use eval, because most people will recommend to stay away from it like the plague. However I recently discovered a use case that made me facepalm for not recognizing it sooner.

If you have cron jobs that you want to run interactively to test, you might view the contents of the file with cat, and copy and paste the cron job to run it. Unfortunately, this involves touching the mouse, which is a sin in my book.

Lets say you have a cron job at /etc/cron.d/repeatme with the contents:

*/10 * * * * root program arg1 arg2

You cant execute this as a script with all the junk in front of it, but we can use cut to get rid of all the junk, wrap it in a subshell, and execute the string with eval

eval $( cut -d ' ' -f 6- /etc/cron.d/repeatme)

The cut command only prints out the 6th field of the file, delimited by spaces. Eval then executes that command.

I used a cron job here as an example, but the concept is to format text from stdout, and then evaluate that text.

The use of eval in this case is not insecure, because we know exactly what we will be evaluating before hand.

I'm pretty certain it is because the DbContext is not at all thread safe. So sharing the thing is never a good idea.

This May be helpful:

//I personally prefer dynamic import (angular 8)
{ path: 'pages', loadChildren: () => import('./pages/pages.module').then(mod => mod.PageModule) }

In child routing it should look like: { path: 'about', component: AboutComponent },

Note that there is no pages in path of child routing and in routerLink or nsRouterLink it should look like routerLink="/pages/about"

I hope thi help someone out there.

I had similar error: "Expecting value: line 1 column 1 (char 0)"

It helped for me to add "myfile.seek(0)", move the pointer to the 0 character

with open(storage_path, 'r') as myfile:
if len(myfile.readlines()) != 0:
    myfile.seek(0)
    Bank_0 = json.load(myfile)

Using parameter binding is definitely the way to go here. Not only is it very quick to write (just add [Parameter(Mandatory=$true)] above your mandatory parameters), but it's also the only option that you won't hate yourself for later.

More below:

[Console]::ReadLine is explicitly forbidden by the FxCop rules for PowerShell. Why? Because it only works in PowerShell.exe, not PowerShell ISE, PowerGUI, etc.

Read-Host is, quite simply, bad form. Read-Host uncontrollably stops the script to prompt the user, which means that you can never have another script that includes the script that uses Read-Host.

You're trying to ask for parameters.

You should use the [Parameter(Mandatory=$true)] attribute, and correct typing, to ask for the parameters.

If you use this on a [SecureString], it will prompt for a password field. If you use this on a Credential type, ([Management.Automation.PSCredential]), the credentials dialog will pop up, if the parameter isn't there. A string will just become a plain old text box. If you add a HelpMessage to the parameter attribute (that is, [Parameter(Mandatory = $true, HelpMessage = 'New User Credentials')]) then it will become help text for the prompt.

If you need to escape JSON inside JSON string, use org.json.JSONObject.quote("your json string that needs to be escaped") seem to work well

for each S3ObjecrSummary in objectListing.getObjectSummaries()

it's looping through each item in the collection

Here is some C code that produces the above mentioned error:

You can even set the prof. pic size to its high resolution that is '1080x1080'

replace "150x150" with 1080x1080 and remove /vp/ from the link.

Your regex "sentence(.*)" is right. To retrieve the contents of the group in parenthesis, you would call:

Pattern p = Pattern.compile( "sentence(.*)" );
Matcher m = p.matcher( "some lame sentence that is awesome" );
if ( m.find() ) {
   String s = m.group(1); // " that is awesome"
}

Note the use of m.find() in this case (attempts to find anywhere on the string) and not m.matches() (would fail because of the prefix "some lame"; in this case the regex would need to be ".*sentence(.*)")

no Regex, no Linq... removes leading and trailing spaces as well as reducing any embedded multiple space segments to one space

string myString = "   0 1 2  3   4               5  ";
myString = string.Join(" ", myString.Split(new char[] { ' ' }, 
StringSplitOptions.RemoveEmptyEntries));

result:"0 1 2 3 4 5"

An old question, but I also have two methods.

For a fixed (predefined) length:

    public static String fill(String text) {
        if (text.length() >= 10)
            return text;
        else
            return "0000000000".substring(text.length()) + text;
    }

For a variable length:

    public static String fill(String text, int size) {
        StringBuilder builder = new StringBuilder(text);
        while (builder.length() < size) {
            builder.append('0');
        }
        return builder.toString();
    }

I believe it would be like this

takedata.match(/(\[.+\])/g);

the g at the end means global, so it doesn't stop at the first match.

It's better if you check visibility like this: if($('#video-over').is(':visible'))

If <!DOCTYPE> is missing in your HTML content you may experience that the browser gives preference to the "user agent stylesheet" over your custom stylesheet. Adding the doctype fixes this.

ANSWER?

I'm using it for an animation for adding items to a cart - a cart icon floats to the cart area from the product "add" button, when clicked:

function addCartItem(opts) {
    for (var i=0; i<opts.qty; i++) {
        setTimeout(function() {
            console.log('ADDED ONE!');
        }, 1000*i);
    }
};

NOTE the duration is in unit times n epocs.

So starting at the the click moment, the animations start epoc (of EACH animation) is the product of each one-second-unit multiplied by the number of items.

epoc: https://en.wikipedia.org/wiki/Epoch_(reference_date)

Hope this helps!

Easy peasy:

var date = DateTime.Parse("14/11/2011"); // may need some Culture help here
Console.Write(date.ToString("yyyy-MM-dd"));

Take a look at DateTime.ToString() method, Custom Date and Time Format Strings and Standard Date and Time Format Strings

string customFormattedDateTimeString = DateTime.Now.ToString("yyyy-MM-dd");

You can return FileResult with this methods:

1: Return FileStreamResult

    [HttpGet("get-file-stream/{id}"]
    public async Task<FileStreamResult> DownloadAsync(string id)
    {
        var fileName="myfileName.txt";
        var mimeType="application/...."; 
        var stream = await GetFileStreamById(id);

        return new FileStreamResult(stream, mimeType)
        {
            FileDownloadName = fileName
        };
    }

2: Return FileContentResult

    [HttpGet("get-file-content/{id}"]
    public async Task<FileContentResult> DownloadAsync(string id)
    {
        var fileName="myfileName.txt";
        var mimeType="application/...."; 
        var fileBytes = await GetFileBytesById(id);

        return new FileContentResult(fileBytes, mimeType)
        {
            FileDownloadName = fileName
        };
    }

Here's a simple javascript function that may be useful from this link.. somehow related but we're using google earth javascript plugin instead of maps

function getApproximateDistanceUnits(point1, point2) {

    var xs = 0;
    var ys = 0;

    xs = point2.getX() - point1.getX();
    xs = xs * xs;

    ys = point2.getY() - point1.getY();
    ys = ys * ys;

    return Math.sqrt(xs + ys);
}

The units tho are not in distance but in terms of a ratio relative to your coordinates. There are other computations related you can substitute for the getApproximateDistanceUnits function link here

Then I use this function to see if a latitude longitude is within the radius

function isMapPlacemarkInRadius(point1, point2, radi) {
    if (point1 && point2) {
        return getApproximateDistanceUnits(point1, point2) <= radi;
    } else {
        return 0;
    }
}

point may be defined as

 $$.getPoint = function(lati, longi) {
        var location = {
            x: 0,
            y: 0,
            getX: function() { return location.x; },
            getY: function() { return location.y; }
        };
        location.x = lati;
        location.y = longi;

        return location;
    };

then you can do your thing to see if a point is within a region with a radius say:

 //put it on the map if within the range of a specified radi assuming 100,000,000 units
        var iconpoint = Map.getPoint(pp.latitude, pp.longitude);
        var centerpoint = Map.getPoint(Settings.CenterLatitude, Settings.CenterLongitude);

        //approx ~200 units to show only half of the globe from the default center radius
        if (isMapPlacemarkInRadius(centerpoint, iconpoint, 120)) {
            addPlacemark(pp.latitude, pp.longitude, pp.name);
        }
        else {
            otherSidePlacemarks.push({
                latitude: pp.latitude,
                longitude: pp.longitude,
                name: pp.name
            });

        }

In order for the client to be able to read cookies from cross-origin requests, you need to have:

1. All responses from the server need to have the following in their header:

   Access-Control-Allow-Credentials: true

2. The client needs to send all requests with withCredentials: true option

In my implementation with Angular 7 and Spring Boot, I achieved that with the following:

Server-side:

@CrossOrigin(origins = "http://my-cross-origin-url.com", allowCredentials = "true")
@Controller
@RequestMapping(path = "/something")
public class SomethingController {
  ...
}

The origins = "http://my-cross-origin-url.com" part will add Access-Control-Allow-Origin: http://my-cross-origin-url.com to every server's response header

The allowCredentials = "true" part will add Access-Control-Allow-Credentials: true to every server's response header, which is what we need in order for the client to read the cookies

Client-side:

import { HttpInterceptor, HttpXsrfTokenExtractor, HttpRequest, HttpHandler, HttpEvent } from "@angular/common/http";
import { Injectable } from "@angular/core";
import { Observable } from 'rxjs';

@Injectable()
export class CustomHttpInterceptor implements HttpInterceptor {

    constructor(private tokenExtractor: HttpXsrfTokenExtractor) {
    }

    intercept(req: HttpRequest<any>, next: HttpHandler): Observable<HttpEvent<any>> {
        // send request with credential options in order to be able to read cross-origin cookies
        req = req.clone({ withCredentials: true });

        // return XSRF-TOKEN in each request's header (anti-CSRF security)
        const headerName = 'X-XSRF-TOKEN';
        let token = this.tokenExtractor.getToken() as string;
        if (token !== null && !req.headers.has(headerName)) {
            req = req.clone({ headers: req.headers.set(headerName, token) });
        }
        return next.handle(req);
    }
}

With this class you actually inject additional stuff to all your request.

The first part req = req.clone({ withCredentials: true });, is what you need in order to send each request with withCredentials: true option. This practically means that an OPTION request will be send first, so that you get your cookies and the authorization token among them, before sending the actual POST/PUT/DELETE requests, which need this token attached to them (in the header), in order for the server to verify and execute the request.

The second part is the one that specifically handles an anti-CSRF token for all requests. Reads it from the cookie when needed and writes it in the header of every request.

The desired result is something like this:

Open $CATALINA_BASE/conf/web.xml and find this

<!-- ==================== Default Session Configuration ================= -->
<!-- You can set the default session timeout (in minutes) for all newly   -->
<!-- created sessions by modifying the value below.                       -->

<session-config>
  <session-timeout>30</session-timeout>
</session-config>

all webapps implicitly inherit from this default web descriptor. You can override session-config as well as other settings defined there in your web.xml.

This is actually from my Tomcat 7 (Windows) but I think 5.5 conf is not very different

It looks like the documentation is just using readStream() to mean:

Ok, we've shown you how to get the InputStream, now your code goes in readStream()

So you should either write your own readStream() method which does whatever you wanted to do with the data in the first place.

My advise is: try not to rely on dependencies when you can easily do it with few lines of codes

Here's what you're trying to achieve in 14 lines of code:

fs.isDir = function(dpath) {
    try {
        return fs.lstatSync(dpath).isDirectory();
    } catch(e) {
        return false;
    }
};
fs.mkdirp = function(dirname) {
    dirname = path.normalize(dirname).split(path.sep);
    dirname.forEach((sdir,index)=>{
        var pathInQuestion = dirname.slice(0,index+1).join(path.sep);
        if((!fs.isDir(pathInQuestion)) && pathInQuestion) fs.mkdirSync(pathInQuestion);
    });
};

For substracting in moment.js:

moment().subtract(1, 'months').format('MMM YYYY');

Documentation:

http://momentjs.com/docs/#/manipulating/subtract/

Before version 2.8.0, the moment#subtract(String, Number) syntax was also supported. It has been deprecated in favor of moment#subtract(Number, String).

  moment().subtract('seconds', 1); // Deprecated in 2.8.0
  moment().subtract(1, 'seconds');

As of 2.12.0 when decimal values are passed for days and months, they are rounded to the nearest integer. Weeks, quarters, and years are converted to days or months, and then rounded to the nearest integer.

  moment().subtract(1.5, 'months') == moment().subtract(2, 'months')
  moment().subtract(.7, 'years') == moment().subtract(8, 'months') //.7*12 = 8.4, rounded to 8

A zombie is already dead, so you cannot kill it. To clean up a zombie, it must be waited on by its parent, so killing the parent should work to eliminate the zombie. (After the parent dies, the zombie will be inherited by pid 1, which will wait on it and clear its entry in the process table.) If your daemon is spawning children that become zombies, you have a bug. Your daemon should notice when its children die and wait on them to determine their exit status.

An example of how you might send a signal to every process that is the parent of a zombie (note that this is extremely crude and might kill processes that you do not intend. I do not recommend using this sort of sledge hammer):

# Don't do this.  Incredibly risky sledge hammer!
kill $(ps -A -ostat,ppid | awk '/[zZ]/ && !a[$2]++ {print $2}')

Read man sshd_config for more details, but you can use the AllowUsers directive in /etc/ssh/sshd_config to limit the set of users who can login.

e.g.

AllowUsers boris

would mean that only the boris user could login via ssh.

The dat file has some lines of extra information before the actual data. Skip them with the skip argument:

read.table("http://www.nilu.no/projects/ccc/onlinedata/ozone/CZ03_2009.dat", 
           header=TRUE, skip=3)

An easy way to check this if you are unfamiliar with the dataset is to first use readLines to check a few lines, as below:

readLines("http://www.nilu.no/projects/ccc/onlinedata/ozone/CZ03_2009.dat", 
          n=10)
# [1] "Ozone data from CZ03 2009"   "Local time: GMT + 0"        
# [3] ""                            "Date        Hour      Value"
# [5] "01.01.2009 00:00       34.3" "01.01.2009 01:00       31.9"
# [7] "01.01.2009 02:00       29.9" "01.01.2009 03:00       28.5"
# [9] "01.01.2009 04:00       32.9" "01.01.2009 05:00       20.5"

Here, we can see that the actual data starts at [4], so we know to skip the first three lines.

Update

If you really only wanted the Value column, you could do that by:

as.vector(
    read.table("http://www.nilu.no/projects/ccc/onlinedata/ozone/CZ03_2009.dat",
               header=TRUE, skip=3)$Value)

Again, readLines is useful for helping us figure out the actual name of the columns we will be importing.

But I don't see much advantage to doing that over reading the whole dataset in and extracting later.

Use the random module: http://docs.python.org/library/random.html

import random
random.sample(set([1, 2, 3, 4, 5, 6]), 2)

This samples the two values without replacement (so the two values are different).

For example:

HTML:

<div class="dropdown">
  <button class="btn btn-default dropdown-toggle" type="button" data-toggle="dropdown">
     <BtnCaption>Select item</BtnCaption>
     <span class="caret"></span>   
  </button>
  <ul class="dropdown-menu">
     <li><a href="#">Option 1</a></li>
     <li><a href="#">Option 2</a></li>
     <li class="disabled"><a href="#">Option 3</a></li>   
  </ul> 
</div>

I use new element BtnCaption for changing only button's text.

Paste into $(document).ready(function () {} the following text

JavaScript:

    $(".dropdown-menu li:not(.disabled) a").click(function () {
        $(this).closest(".dropdown").find(".btn BtnCaption").text($(this).text()));
    });

:not(.disabled) don't allow use the disabled menu items

I do not think the warnings you have received are related. I had the same warnings which turned out to be the chrome extension React Dev Tools. Removed the extension and the errors have gone.

This function returns all user defined routines in current database.

SELECT pg_get_functiondef(p.oid) FROM pg_proc p
INNER JOIN pg_namespace ns ON p.pronamespace = ns.oid
WHERE ns.nspname = 'public';

I didn't find an intuitive explanation on the web, so now that I worked it out, here's my solution. This is for infinite lines (what I needed), not segments.

Some terms you might remember:

A line is defined as y = mx + b OR y = slope * x + y-intercept

Slope = rise over run = dy / dx = height / distance

Y-intercept is where the line crosses the Y axis, where X = 0

Given those definitions, here are some functions:

def slope(P1, P2):
    # dy/dx
    # (y2 - y1) / (x2 - x1)
    return(P2[1] - P1[1]) / (P2[0] - P1[0])

def y_intercept(P1, slope):
    # y = mx + b
    # b = y - mx
    # b = P1[1] - slope * P1[0]
    return P1[1] - slope * P1[0]

def line_intersect(m1, b1, m2, b2):
    if m1 == m2:
        print ("These lines are parallel!!!")
        return None
    # y = mx + b
    # Set both lines equal to find the intersection point in the x direction
    # m1 * x + b1 = m2 * x + b2
    # m1 * x - m2 * x = b2 - b1
    # x * (m1 - m2) = b2 - b1
    # x = (b2 - b1) / (m1 - m2)
    x = (b2 - b1) / (m1 - m2)
    # Now solve for y -- use either line, because they are equal here
    # y = mx + b
    y = m1 * x + b1
    return x,y

Here's a simple test between two (infinite) lines:

A1 = [1,1]
A2 = [3,3]
B1 = [1,3]
B2 = [3,1]
slope_A = slope(A1, A2)
slope_B = slope(B1, B2)
y_int_A = y_intercept(A1, slope_A)
y_int_B = y_intercept(B1, slope_B)
print(line_intersect(slope_A, y_int_A, slope_B, y_int_B))

Output:

(2.0, 2.0)

input { float: right; clear: both; }

Other answers are correct -- whether a character is invisible or not depends on what font you use. This seems to be a pretty good list to me of characters that are truly invisible (not even space). It contains some chars that the other lists are missing.

            '\u200E', // Left-To-Right Mark
            '\u200F', // Right-To-Left Mark
            '\u061C', // Arabic Letter Mark
            '\uFEFF', // Byte Order Mark
            '\u180E', // Mongolian Vowel Separator
            '\u00AD'  // soft-hyphen

In addition to standard net/http package, you can consider using my GoRequest which wraps around net/http and make your life easier without thinking too much about json or struct. But you can also mix and match both of them in one request! (you can see more details about it in gorequest github page)

So, in the end your code will become like follow:

func main() {
    url := "http://restapi3.apiary.io/notes"
    fmt.Println("URL:>", url)
    request := gorequest.New()
    titleList := []string{"title1", "title2", "title3"}
    for _, title := range titleList {
        resp, body, errs := request.Post(url).
            Set("X-Custom-Header", "myvalue").
            Send(`{"title":"` + title + `"}`).
            End()
        if errs != nil {
            fmt.Println(errs)
            os.Exit(1)
        }
        fmt.Println("response Status:", resp.Status)
        fmt.Println("response Headers:", resp.Header)
        fmt.Println("response Body:", body)
    }
}

This depends on how you want to achieve. I made this library because I have the same problem with you and I want code that is shorter, easy to use with json, and more maintainable in my codebase and production system.

This works in all browsers:

window.location.href = '...';

If you wanted to change the page without it reflecting in the browser back history, you can do:

window.location.replace('...');

Opening the debug console in Chrome, or even looking at the html source file (after it is loaded in the browser), make sure that all the paths there are valid (i.e. when you follow a link you get to it's content, and not an error). When something is not valid, fix the path (e.g. get rid of the server specific part and make sure you only refer to files that are part of your extension through paths like /js/jquery-123-min.js).

This happened to me as well. For me, Postfix was located at the same server as the PHP script, and the error was happening when I would be using SMTP authentication and smtp.domain.com instead of localhost.

So when I commented out these lines:

$mail->SMTPAuth = true;
$mail->SMTPSecure = "tls";

and set the host to

$mail->Host = "localhost";

instead

$mail->Host = 'smtp.mydomainiuse.com'

and it worked :)

the reason why it returns < filter object > is that, filter is class instead of built-in function.

help(filter) you will get following: Help on class filter in module builtins:
