Looks like whatever is in your Animation Drawable definition is too much memory to decode and sequence. The idea is that it loads up all the items and make them in an array and swaps them in and out of the scene according to the timing specified for each frame.

If this all can't fit into memory, it's probably better to either do this on your own with some sort of handler or better yet just encode a movie with the specified frames at the corresponding images and play the animation through a video codec.

Its a CORS issue, your api cannot be accessed directly from remote or different origin, In order to allow other ip address or other origins from accessing you api, you should add the 'Access-Control-Allow-Origin' on the api's header, you can set its value to '*' if you want it to be accessible to all, or you can set specific domain or ips like 'http://siteA.com' or 'http://192. ip address ';

Include this on your api's header, it may vary depending on how you are displaying json data,

if your using ajax, to retrieve and display data your header would look like this,

$.ajax({
   url: '',
   headers: {  'Access-Control-Allow-Origin': 'http://The web site allowed to access' },
   data: data,
   type: 'dataType',
   /* etc */
   success: function(jsondata){

   }
})

I moved implementation to module-level build.gradle from root-level build.gradle. It solves the issue.

Here's another way to plot the data, involves turning the date_time into an index, this might help you for future slicing

#convert column to datetime
trip_data['lpep_pickup_datetime'] = pd.to_datetime(trip_data['lpep_pickup_datetime'])
#turn the datetime to an index
trip_data.index = trip_data['lpep_pickup_datetime']
#Plot
trip_data['Trip_distance'].plot(kind='hist')
plt.show()

You did not post the code generated by the compiler, so there' some guesswork here, but even without having seen it, one can say that this:

test rax, 1
jpe even

... has a 50% chance of mispredicting the branch, and that will come expensive.

The compiler almost certainly does both computations (which costs neglegibly more since the div/mod is quite long latency, so the multiply-add is "free") and follows up with a CMOV. Which, of course, has a zero percent chance of being mispredicted.

Just remove this line from build.gradle(Project folder)

apply plugin: 'com.google.gms.google-services'

Now rebuild the application. works fine Happy coding

If who have error , try it with sudo:

sudo npm install -g react-native-cli

If you're facing the problem after updating the google play services 9.8.0 add this to your dependencies :

`dependencies {
compile fileTree(include: ['*.jar'], dir: 'libs')
testCompile 'junit:junit:4.12'
compile 'com.google.firebase:firebase-messaging:9.8.0'
compile 'com.google.android.gms:play-services-maps:9.8.0'
compile 'com.google.android.gms:play-services-location:9.8.0'
compile 'com.google.firebase:firebase-database:9.8.0'
compile 'com.google.firebase:firebase-auth:9.8.0'
compile 'com.google.firebase:firebase-crash:9.8.0'
compile 'com.google.maps.android:android-maps-utils:0.4.4'
compile 'com.google.android.gms:play-services-appindexing:9.8.0'

}

This question have many answers but, if you not solved your error yet, this could work:

Sometimes we import different versions from google products/APIs so, try to organize your gradle file to solve the: Mixing versions warning

Wrong syntax. Here you are:

insert into user_by_category (game_category,customer_id) VALUES ('Goku','12');

or:

insert into user_by_category ("game_category","customer_id") VALUES ('Kakarot','12');

The second one is normally used for case-sensitive column names.

You can try this:

<style name="MyCustomTabLayout" parent="Widget.Design.TabLayout">
    <item name="tabBackground">@drawable/background</item>
</style>

In your background xml file:

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_selected="true" android:drawable="@color/white" />
    <item android:drawable="@color/black" />
</selector>

startActivity(new Intent(this, Katra_home.class));

try this one it will be work

I was facing the same problem in IntelliJ. It was working from command line though.

I found the issue was because of an improper Gradle config in the IDE. I wasn't using the "default Gradle wrapper" as recommended:

I faced with same problem. Solution that worked for me. If you use v7.Toolbar you must use theme extended from Theme.AppCompat.* You can't use theme extended from android:Theme.Material.* because they have different style attributes.

Hope it will helpful.

This is caused by MySQL having a strict mode set which won’t allow INSERT or UPDATE commands with empty fields where the schema doesn’t have a default value set.

There are a couple of fixes for this.

First ‘fix’ is to assign a default value to your schema. This can be done with a simple ALTER command:

ALTER TABLE `details` CHANGE COLUMN `delivery_address_id` `delivery_address_id` INT(11) NOT NULL DEFAULT 0 ;

However, this may need doing for many tables in your database schema which will become tedious very quickly. The second fix is to remove sql_mode STRICT_TRANS_TABLES on the mysql server.

If you are using a brew installed MySQL you should edit the my.cnf file in the MySQL directory. Change the sql_mode at the bottom:

#sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES
sql_mode=NO_ENGINE_SUBSTITUTION

Save the file and restart Mysql.

Determining of root cause is not an issue since Go 1.8; field name now is shown in the error message:

The good thing is, this one is really easily and deterministically to analyze: Either, the msi package is really not installed on the system or you're doing something wrong. Of course the correct call is:

msiexec /x {A4BFF20C-A21E-4720-88E5-79D5A5AEB2E8}

(Admin rights needed of course- With curly braces without any quotes here- quotes are only needed, if paths or values with blank are specified in the commandline.)
If the message is: "This action is only valid for products that are currently installed", then this is true. Either the package with this ProductCode is not installed or there is a typo.

To verify where the fault is:

1. First try to right click on the (probably) installed .msi file itself. You will see (besides "Install" and "Repair") an Uninstall entry. Click on that.
   a) If that uninstall works, your msi has another ProductCode than you expect (maybe you have the wrong WiX source or your build has dynamic logging where the ProductCode changes).
   b) If that uninstall gives the same "...only valid for products already installed" the package is not installed (which is obviously a precondition to be able to uninstall it).

2. If 1.a) was the case, you can look for the correct ProductCode of your package, if you open your msi file with Orca, Insted or another editor/tool. Just google for them. Look there in the table with the name "Property" and search for the string "ProductCode" in the first column. In the second column there is the correct value.

There are no other possibilities.

Just a suggestion for the used commandline: I would add at least the "/qb" for a simple progress bar or "/qn" parameter (the latter for complete silent uninstall, but makes only sense if you are sure it works).

Today I ran into the same error, however, i was using Android Studio 1.0.2. What i did tot fix the problem was that i started a project with minimum SDK 4.4 (API 19) so when i checked the version i noticed that at File->ProjectStructure->app i found Android 5 as a compile SDK Version. I changed that back to 4.4.

use getContext() instead of MainActivity.this

Intent intent = new Intent(getContext(), SecondActivity.class);
startActivity(start);

Add this name field in navigation

android:name="androidx.navigation.fragment.NavHostFragment"

   <fragment
             android:id="@+id/container"
             android:layout_width="match_parent"
             android:layout_height="0dp"
             android:name="androidx.navigation.fragment.NavHostFragment"
             app:navGraph="@navigation/navigation"
             app:layout_constraintBottom_toTopOf="@+id/bottomNavigationView"
             app:layout_constraintTop_toTopOf="parent">

You just have to reset the values you don't want to their defaults. No need to get into a mess by using !important.

#zoomTarget .slikezamenjanje img {
    max-height: auto;
    padding-right: 0px;
}

Hatting

I think the key datum you are missing is that CSS comes with default values. If you want to override a value, set it back to its default, which you can look up.

For example, all CSS height and width attributes default to auto.

Based on what he answered @chahat jain :

"When we use the viewPager, a good way to access the fragment instance in activity is instantiateItem(viewpager,index). //index- index of fragment of which you want instance."

If you want to do that in kotlin

val fragment =  mv_viewpager.adapter!!.instantiateItem(mv_viewpager, 0) as Fragment
                if ( fragment is YourFragmentFragment)
                 {
                    //DO somthign 
                 }

0 to the fragment instance of 0

//=========================================================================// //#############################Example of uses #################################// //=========================================================================//

Here is a complete example to get a losest vision about

here is my veiewPager in the .xml file

   ...
    <android.support.v4.view.ViewPager
                android:id="@+id/mv_viewpager"
                android:layout_width="match_parent"
                android:layout_height="match_parent"

And the home activity where i insert the tab

            override fun onQueryTextChange(newText: String): Boolean {

                if (mv_viewpager.currentItem  ==0)
                {
                    val fragment =  mv_viewpager.adapter!!.instantiateItem(mv_viewpager, 0) as Fragment

                return true

        })
        return super.onCreateOptionsMenu(menu)
    }
        ...

}

Passing arguments between fragments. This is a fairly late to answer this question but it could help someone! Fragment_1.java

Bundle i = new Bundle(); 
            i.putString("name", "Emmanuel");

            Fragment_1 frag = new Fragment_1();
            frag.setArguments(i);
            FragmentManager fragmentManager = getFragmentManager();
            fragmentManager.beginTransaction()
                    .replace(R.id.content_frame
                            , new Fragment_2())
                    .commit();

Then in your Fragment_2.java you can get the paramaters normally within your onActivityCreated e.g

 Intent intent = getActivity().getIntent();
    if (intent.getExtras() != null) {
        String name =intent.getStringExtra("name");
    }

Since the behavior is kind of strange, I have done some testing on the behavior, and here's my result:

TL;DR

If you are:

• In a form, and
• uses onclick="xxx()" on an element
• don't add id="xxx" or name="xxx" to that element
  • (e.g. <form><button id="totalbandwidth" onclick="totalbandwidth()">BAD</button></form> )

Here's are some test and their result:

Control sample (can successfully call function)

function totalbandwidth(){ alert("Total Bandwidth > 9000Mbps"); }

<form onsubmit="return false;">
  <button onclick="totalbandwidth()">SUCCESS</button>
</form>

Add id to button (failed to call function)

function totalbandwidth(){ alert("Total Bandwidth > 9000Mbps"); }

<form onsubmit="return false;">
  <button id="totalbandwidth" onclick="totalbandwidth()">FAILED</button>
</form>

Add name to button (failed to call function)

function totalbandwidth(){ alert("Total Bandwidth > 9000Mbps"); }

<form onsubmit="return false;">
  <button name="totalbandwidth" onclick="totalbandwidth()">FAILED</button>
</form>

Add value to button (can successfully call function)

function totalbandwidth(){ alert("Total Bandwidth > 9000Mbps"); }

<form onsubmit="return false;">
  <input type="button" value="totalbandwidth" onclick="totalbandwidth()" />SUCCESS
</form>

Add id to button, but not in a form (can successfully call function)

function totalbandwidth(){ alert("Total Bandwidth > 9000Mbps"); }

<button id="totalbandwidth" onclick="totalbandwidth()">SUCCESS</button>

Add id to another element inside the form (can successfully call function)

function totalbandwidth(){ alert("The answer is no, the span will not affect button"); }

<form onsubmit="return false;">
<span name="totalbandwidth" >Will this span affect button? </span>
<button onclick="totalbandwidth()">SUCCESS</button>
</form>

If you need to change the path, add this after your .config in your app file. Then you can do $location.path('/sampleurl', false); to prevent reloading

app.run(['$route', '$rootScope', '$location', function ($route, $rootScope, $location) {
    var original = $location.path;
    $location.path = function (path, reload) {
        if (reload === false) {
            var lastRoute = $route.current;
            var un = $rootScope.$on('$locationChangeSuccess', function () {
                $route.current = lastRoute;
                un();
            });
        }
        return original.apply($location, [path]);
    };
}])

Credit goes to https://www.consolelog.io/angularjs-change-path-without-reloading for the most elegant solution I've found.

Try setting an id (android:id="@+id/maps_dialog") for your mapView parent layout. Works for me.

In IntelliJ IDEA (updated for IntelliJ 12):

1. Create a file ~/android-sdk/extras/google/google_play_services/libproject/google-play-services_lib/src/dummy.java containing class dummy {}.
2. File->Import Module-> ~/android-sdk/extras/google/google_play_services/libproject/google-play-services_lib
3. Create Module from Existing Sources
4. Next->Next->Next->Next->Finish
5. File->Project Structure->Modules->YourApp
6. +->Module Dependency->Google-play-services_lib (The + button is in the top right corner of the dialog.)
7. +->Jars or directories->~/android-sdk/extras/google/google_play_services/libproject/google-play-services_lib/libs/google-play-services.jar
8. Use the up/down arrows to move <Module source> to the bottom of the list.

You can delete dummy.java if you like.

Edit: After using this for a while I've found that there is a small flaw/bug. IDEA will sometimes complain about not being able to open a .iml project file in the google-play-services_lib directory, despite the fact that you never told it there was a project there. If that happens, rebuilding the project solves the problem, at least until it comes back.

I am migrating from V1 to V2 of Google Maps. I was getting this failure trying to run the app via Eclipse. The root cause for me was using my release certificate keystore rather than the Android debug keystore which is what gets used when you run it via Eclipse. The following command (OSX/Linux) will get you the SHA1 key of the debug keystore:

keytool -list -v -keystore ~/.android/debug.keystore -alias androiddebugkey -storepass android -keypass android

If you are using Windows 7 instead, you would use this command:

keytool -list -v -keystore "%USERPROFILE%\.android\debug.keystore" -alias androiddebugkey -storepass android -keypass android

It is probably best to uninstall your app completely from your device before trying with a new key as Android caches the security credentials.

What can you do if you need to make a change to a file, but don’t know the file’s encoding? If you know the encoding is ASCII-compatible and only want to examine or modify the ASCII parts, you can open the file with the surrogateescape error handler:

with open(fname, 'r', encoding="ascii", errors="surrogateescape") as f:
    data = f.read()

You can use something like code below, if you need to affect only specific value, and not touch others:

view.getLayoutParams().width = newWidth;

Make sure you're using the correct SDK when compiling/running and also, make sure you use source/target 1.7.

I have had the same problem with a simple Activity carrying only one fragment (which would get replaced sometimes). I then realized I use onSaveInstanceState only in the fragment (and onCreateView to check for savedInstanceState), not in the activity.

On device turn the activity containing the fragments gets restarted and onCreated is called. There I did attach the required fragment (which is correct on the first start).

On the device turn Android first re-created the fragment that was visible and then called onCreate of the containing activity where my fragment was attached, thus replacing the original visible one.

To avoid that I simply changed my activity to check for savedInstanceState:

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

if (savedInstanceState != null) {
/**making sure you are not attaching the fragments again as they have 
 been 
 *already added
 **/
 return; 
 }
 else{
  // following code to attach fragment initially
 }

 }

I did not even Overwrite onSaveInstanceState of the activity.

There are errors here :

var formTag = document.getElementsByTagName("form"), // form tag is an array
selectListItem = $('select'),
makeSelect = document.createElement('select'),
makeSelect.setAttribute("id", "groups");

The code must change to:

var formTag = document.getElementsByTagName("form");
var selectListItem = $('select');
var makeSelect = document.createElement('select');
makeSelect.setAttribute("id", "groups");

By the way, there is another error at line 129 :

var createLi.appendChild(createSubList);

Replace it with:

createLi.appendChild(createSubList);

An old post, but I was surprised about the most up-voted answer.

The proper solution for this should be to cancel the asynctask in onStop (or wherever appropriate in your fragment). This way you don't introduce a memory leak (an asynctask keeping a reference to your destroyed fragment) and you have better control of what is going on in your fragment.

@Override
public void onStop() {
    super.onStop();
    mYourAsyncTask.cancel(true);
}

They have wrapped most stuff need to solve your problem, one of the tests looks like this:

String filename = CSSURLEmbedderTest.class.getResource("folder.png").getPath().replace("%20", " ");
String code = "background: url(folder.png);";

StringWriter writer = new StringWriter();
embedder = new CSSURLEmbedder(new StringReader(code), true);
embedder.embedImages(writer, filename.substring(0, filename.lastIndexOf("/")+1));

String result = writer.toString();
assertEquals("background: url(" + folderDataURI + ");", result);

I just had this issue building react-native app when I try to install Pod. I had to export 2 variables:

export CC=/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/cc
CPP='/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/cc -E'

To learn what row was selected, add a ListSelectionListener, as shown in How to Use Tables in the example SimpleTableSelectionDemo. A JList can be constructed directly from the linked list's toArray() method, and you can add a suitable listener to it for details.

I think what you want is some form of the Ford–Fulkerson algorithm which is based on BFS. Its used to calculate the max flow of a network, by finding all augmenting paths between two nodes.

How I did it with a pivot in dynamic sql (#AccPurch was created prior to this)

DECLARE @sql AS nvarchar(MAX)
declare @Month Nvarchar(1000)

--DROP TABLE #temp
select distinct YYYYMM into #temp from #AccPurch AS ap
SELECT  @Month = COALESCE(@Month, '') + '[' + CAST(YYYYMM AS VarChar(8)) + '],' FROM    #temp

SELECT   @Month= LEFT(@Month,len(@Month)-1)


SET @sql = N'SELECT UserID, '+ @Month + N' into ##final_Donovan_12345 FROM (
Select ap.AccPurch ,
       ap.YYYYMM ,
       ap.UserID ,
       ap.AccountNumber
FROM #AccPurch AS ap 
) p
Pivot (SUM(AccPurch) FOR YYYYMM IN ('+@Month+ N')) as pvt'


EXEC sp_executesql @sql

Select * INTO #final From ##final_Donovan_12345

DROP TABLE  ##final_Donovan_12345

Select * From #final AS f

The error shown in visual studio for the project (Let's say A) does not have issues. When I looked at the output window for the build line by line for each project, I saw that it was complaining about another project (B) that had been referred as assembly in project A. Project B added into the solution. But it had not been referred in the project A as project reference instead as assembly reference from different location. That location contains the assembly which compiled for Platform AnyCpu. Then I removed the assembly reference from the project A and added project B as a reference. It started compiling. Not sure though how this fix worked.

Another approach to this would be to download Jan Karel Pieterse's free Open XML class module from this page: Editing elements in an OpenXML file using VBA

With this added to your VBA project, you can unzip the Excel file, use VBA to modify the XML, then use the class to rezip the files.

In the controller, you need to add the login object as an attribute of the model:

model.addAttribute("login", new Login());

Like this:

@RequestMapping(value = "/", method = RequestMethod.GET) 
public String displayLogin(Model model) { 
    model.addAttribute("login", new Login()); 
    return "login"; 
}

make sure columns are identical(of same type) and if reference column is not primary_key, make sure it is INDEXED.

If checked:

$( "SELECTOR" ).attr( "checked" )  // Returns ‘true’ if present on the element, returns undefined if not present
$( "SELECTOR" ).prop( "checked" ) // Returns true if checked, false if unchecked.
$( "SELECTOR" ).is( ":checked" ) // Returns true if checked, false if unchecked.

Get the checked val:

$( "SELECTOR:checked" ).val()

Get the checked val numbers:

$( "SELECTOR:checked" ).length

Check or uncheck checkbox

$( "SELECTOR" ).prop( "disabled", false );
$( "SELECTOR" ).prop( "checked", true );

To go the full manual route: This method converts doubles to strings by shifting the number's decimal point around and using floor (to long) and modulus to extract the digits. Also, it uses counting by base division to figure out the place where the decimal point belongs. It can also "delete" higher parts of the number once it reaches the places after the decimal point, to avoid losing precision with ultra-large doubles. See commented code at the end. In my testing, it is never less precise than the Java float representations themselves, when they actually show these imprecise lower decimal places.

/**
 * Convert the given double to a full string representation, i.e. no scientific notation
 * and always twelve digits after the decimal point.
 * @param d The double to be converted
 * @return A full string representation
 */
public static String fullDoubleToString(final double d) {
    // treat 0 separately, it will cause problems on the below algorithm
    if (d == 0) {
        return "0.000000000000";
    }
    // find the number of digits above the decimal point
    double testD = Math.abs(d);
    int digitsBeforePoint = 0;
    while (testD >= 1) {
        // doesn't matter that this loses precision on the lower end
        testD /= 10d;
        ++digitsBeforePoint;
    }

    // create the decimal digits
    StringBuilder repr = new StringBuilder();
    // 10^ exponent to determine divisor and current decimal place
    int digitIndex = digitsBeforePoint;
    double dabs = Math.abs(d);
    while (digitIndex > 0) {
        // Recieves digit at current power of ten (= place in decimal number)
        long digit = (long)Math.floor(dabs / Math.pow(10, digitIndex-1)) % 10;
        repr.append(digit);
        --digitIndex;
    }

    // insert decimal point
    if (digitIndex == 0) {
        repr.append(".");
    }

    // remove any parts above the decimal point, they create accuracy problems
    long digit = 0;
    dabs -= (long)Math.floor(dabs);
    // Because of inaccuracy, move to entirely new system of computing digits after decimal place.
    while (digitIndex > -12) {
        // Shift decimal point one step to the right
        dabs *= 10d;
        final var oldDigit = digit;
        digit = (long)Math.floor(dabs) % 10;
        repr.append(digit);

        // This may avoid float inaccuracy at the very last decimal places.
        // However, in practice, inaccuracy is still as high as even Java itself reports.
        // dabs -= oldDigit * 10l;
        --digitIndex;
    }

    return repr.insert(0, d < 0 ? "-" : "").toString(); 
}

Note that while StringBuilder is used for speed, this method can easily be rewritten to use arrays and therefore also work in other languages.

I ran into this problem . I was checking for version number and enabling the action bar only if it is greater or equal to Honeycomb , but it was returning null. I found the reason and root cause was that I had disabled the Holo Theme style in style.xml under values-v11 folder.

I prefix this reply with "you shouldn't use a regular expression to parse XML -- it's only going to result in edge cases that don't work right, and a forever-increasing-in-complexity regex while you try to fix it."

That being said, you need to proceed by matching the string and grabbing the group you want:

if (m.matches())
{
   String result = m.group(1);
   // do something with result
}

I was having the same problem as you are facing. None of the tips on top helped me. Later, I found that all I had to do is fix my imports from:

import android.app.Fragment;

to:

import android.support.v4.app.Fragment;

If you are ok using an external plugin to do that you can use Header and Footer Scripts plugin

From the description:

Many WordPress Themes do not have any options to insert header and footer scripts in your site or . It helps you to keep yourself from theme lock. But, sometimes it also causes some pain for many. like where should I insert Google Analytics code (or any other web-analytics codes). This plugin is one stop and lightweight solution for that. With this "Header and Footer Script" plugin will be able to inject HTML tags, JS and CSS codes to and easily.

Greetings if i get you right you need a JavaScript function that doing it

function report(v) {
//To Do
  switch(v) {
    case "daily":
      //Do something
      break;
    case "monthly":
      //Do somthing
      break;
    }
  }

By changing proxy settings to "no proxy" in netbeans the tomcat prbolem got solved.Try this it's seriously working.

Just for the record: for me it turned out that it was the gem called 'mysql' ... obviously this is working with US-ASCII 8 bit by default. So changing it to the gem called mysql2 (the 2 is the important point here) solved all of my issues.

I looked @ the gem list posted above - Michael Koper has obviously mysql2 installed but I posted this in case someone has this issue as well .. (took me some time to figure out).

If you dislike this answer please comment and I will delete it.

P.S: German umlauts (ä,ö and ü) screwed it out with mysql

I wrote a class that implemented the GDI method for screen capture. I too wanted extra speed so, after discovering the DirectX method (via GetFrontBuffer) I tried that, expecting it to be faster.

I was dismayed to find that GDI performs about 2.5x faster. After 100 trials capturing my dual monitor display, the GDI implementation averaged 0.65s per screen capture, while the DirectX method averaged 1.72s. So GDI is definitely faster than GetFrontBuffer, according to my tests.

I was unable to get Brandrew's code working to test DirectX via GetRenderTargetData. The screen copy came out purely black. However, it could copy that blank screen super fast! I'll keep tinkering with that and hope to get a working version to see real results from it.

ViewFlipper loads all images into memory during layout inflating. Because my images are big it takes many memory, I replaced ViewFlipper with ImageSwitcher which can change the images with animation like ViewFlipper but it loads only one image at the time.

Two things. First, you must base64 decode the mykey.pem file yourself. Second, the openssl private key format is specified in PKCS#1 as the RSAPrivateKey ASN.1 structure. It is not compatible with java's PKCS8EncodedKeySpec, which is based on the SubjectPublicKeyInfo ASN.1 structure. If you are willing to use the bouncycastle library you can use a few classes in the bouncycastle provider and bouncycastle PKIX libraries to make quick work of this.

import java.io.BufferedReader;
import java.io.FileReader;
import java.security.KeyPair;
import java.security.Security;

import org.bouncycastle.jce.provider.BouncyCastleProvider;
import org.bouncycastle.openssl.PEMKeyPair;
import org.bouncycastle.openssl.PEMParser;
import org.bouncycastle.openssl.jcajce.JcaPEMKeyConverter;

// ...   

String keyPath = "mykey.pem";
BufferedReader br = new BufferedReader(new FileReader(keyPath));
Security.addProvider(new BouncyCastleProvider());
PEMParser pp = new PEMParser(br);
PEMKeyPair pemKeyPair = (PEMKeyPair) pp.readObject();
KeyPair kp = new JcaPEMKeyConverter().getKeyPair(pemKeyPair);
pp.close();
samlResponse.sign(Signature.getInstance("SHA1withRSA").toString(), kp.getPrivate(), certs);

Well another possible cause of this can be simple line break at end of each line and shebang line If you have been coding in windows IDE its possible that windows has added its own line break at the end of each line and when you try to run it on linux the line break cause problems

public class MyView extends View {

GestureDetector gestureDetector;

public MyView(Context context, AttributeSet attrs) {
    super(context, attrs);
            // creating new gesture detector
    gestureDetector = new GestureDetector(context, new GestureListener());
}

// skipping measure calculation and drawing

    // delegate the event to the gesture detector
@Override
public boolean onTouchEvent(MotionEvent e) {
    return gestureDetector.onTouchEvent(e);
}


private class GestureListener extends GestureDetector.SimpleOnGestureListener {

    @Override
    public boolean onDown(MotionEvent e) {
        return true;
    }
    // event when double tap occurs
    @Override
    public boolean onDoubleTap(MotionEvent e) {
        float x = e.getX();
        float y = e.getY();

        Log.d("Double Tap", "Tapped at: (" + x + "," + y + ")");

        return true;
    }
}
}

The answer really depends on the complexity you want. For example, I want to outline all my indents with a vertical bar, so my indent string is determined as follows:

return new string(Enumerable.Range(0, indentSize*indent).Select(
  n => n%4 == 0 ? '|' : ' ').ToArray());

I find the existing explanations too gobbledygook. Here's my explanation in plain English:

STA: If a thread creates a COM object that's set to STA (when calling CoCreateXXX you can pass a flag that sets the COM object to STA mode), then only this thread can access this COM object (that's what STA means - Single Threaded Apartment), other thread trying to call methods on this COM object is under the hood silently turned into delivering messages to the thread that creates(owns) the COM object. This is very much like the fact that only the thread that created a UI control can access it directly. And this mechanism is meant to prevent complicated lock/unlock operations.

MTA: If a thread creates a COM object that's set to MTA, then pretty much every thread can directly call methods on it.

That's pretty much the gist of it. Although technically there're some details I didn't mention, such as in the 'STA' paragraph, the creator thread must itself be STA. But this is pretty much all you have to know to understand STA/MTA/NA.

I was looking for a way to format numbers without leading or trailing spaces, periods, zeros (except one leading zero for numbers less than 1 that should be present).

This is frustrating that such most usual formatting can't be easily achieved in Oracle.

Even Tom Kyte only suggested long complicated workaround like this:

case when trunc(x)=x
    then to_char(x, 'FM999999999999999999')
    else to_char(x, 'FM999999999999999.99')
end x

But I was able to find shorter solution that mentions the value only once:

rtrim(to_char(x, 'FM999999999999990.99'), '.')

This works as expected for all possible values:

select 
    to_char(num, 'FM99.99') wrong_leading_period,
    to_char(num, 'FM90.99') wrong_trailing_period,
    rtrim(to_char(num, 'FM90.99'), '.') correct
from (
  select num from (select 0.25 c1, 0.1 c2, 1.2 c3, 13 c4, -70 c5 from dual)
  unpivot (num for dummy in (c1, c2, c3, c4, c5))
) sampledata;

    | WRONG_LEADING_PERIOD | WRONG_TRAILING_PERIOD | CORRECT |
    |----------------------|-----------------------|---------|
    |                  .25 |                  0.25 |    0.25 |
    |                   .1 |                   0.1 |     0.1 |
    |                  1.2 |                   1.2 |     1.2 |
    |                  13. |                   13. |      13 |
    |                 -70. |                  -70. |     -70 |

Still looking for even shorter solution.

There is a shortening approarch with custom helper function:

create or replace function str(num in number) return varchar2
as
begin
    return rtrim(to_char(num, 'FM999999999999990.99'), '.');
end;

But custom pl/sql functions have significant performace overhead that is not suitable for heavy queries.

Use WORKSPACE environment variable to change workspace directory.

If doing using Jenkinsfile, use following code :

dir("${env.WORKSPACE}/aQA"){
    sh "pwd"
}

I think the problem is given in the error message, although it is not very easy to spot:

IndexError: too many indices for array
xs  = data[:, col["l1"     ]]

'Too many indices' means you've given too many index values. You've given 2 values as you're expecting data to be a 2D array. Numpy is complaining because data is not 2D (it's either 1D or None).

This is a bit of a guess - I wonder if one of the filenames you pass to loadfile() points to an empty file, or a badly formatted one? If so, you might get an array returned that is either 1D, or even empty (np.array(None) does not throw an Error, so you would never know...). If you want to guard against this failure, you can insert some error checking into your loadfile function.

I highly recommend in your for loop inserting:

print(data)

This will work in Python 2.x or 3.x and might reveal the source of the issue. You might well find it is only one value of your outputs_l1 list (i.e. one file) that is giving the issue.

Here is a link that has a performance test you can run. find() is actually about 2 times faster than children().

Vadiklk,

Why ...? Reason is that static variable is initialized only once, and maintains its value throughout the program. means, you can use static variable between function calls. also it can be used to count "how many times a function is called"

main()
{
   static int var = 5;
   printf("%d ",var--);
   if(var)
      main();
} 

and answer is 5 4 3 2 1 and not 5 5 5 5 5 5 .... (infinite loop) as you are expecting. again, reason is static variable is initialized once, when next time main() is called it will not be initialize to 5 because it is already initialized in the program.So we can change the value but can not reinitialized. Thats how static variable works.

or you can consider as per storage: static variables are stored on Data Section of a program and variables which are stored in Data Section are initialized once. and before initialization they are kept in BSS section.

In turn Auto(local) variables are stored on Stack and all the variables on stack reinitialized all time when function is called as new FAR(function activation record) is created for that.

okay for more understanding, do the above example without "static" and let you know what will be the output. That make you to understand the difference between these two.

Thanks Javed

The accepted answer will work if you can easily reproduce the issue. However, as a matter of best practice, you should be catching any exceptions (and logging) that are executed within a task. Otherwise, your application will crash if anything unexpected occurs within the task.

Task.Factory.StartNew(x=>
   throw new Exception("I didn't account for this");
)

However, if we do this, at least the application does not crash.

Task.Factory.StartNew(x=>
   try {
      throw new Exception("I didn't account for this");
   }
   catch(Exception ex) {
      //Log ex
   }
)

To change the default "sub-menu" class name, there is simple way. You can just change it in wordpress file.

location : www/project_name/wp-includes/nav-menu-template.php.

open this file and at line number 49, change the name of sub-menu class with your custom class.

Or you can also add your custom class next to sub-menu.

Done.

It worked for me.I used wordpress-4.4.1.

I hope mine helps

template <typename t_int>
std::array<uint8_t, sizeof (t_int)> int2array(t_int p_value) {
    static const uint8_t _size_of (static_cast<uint8_t>(sizeof (t_int)));
    typedef std::array<uint8_t, _size_of> buffer;
    static const std::array<uint8_t, 8> _shifters = {8*0, 8*1, 8*2, 8*3, 8*4, 8*5, 8*6, 8*7};

    }
    return _res;
}

Are you meaning?

data2 <- data1[good,]

With

data1[good]

you're selecting columns in a wrong way (using a logical vector of complete rows).

Consider that parameter pollutant is not used; is it a column name that you want to extract? if so it should be something like

data2 <- data1[good, pollutant]

Furthermore consider that you have to rbind the data.frames inside the for loop, otherwise you get only the last data.frame (its completed.cases)

And last but not least, i'd prefer generating filenames eg with

id <- 1:322
paste0( directory, "/", gsub(" ", "0", sprintf("%3d",id)), ".csv")

A little modified chunk of ?sprintf

The string fmt (in our case "%3d") contains normal characters, which are passed through to the output string, and also conversion specifications which operate on the arguments provided through .... The allowed conversion specifications start with a % and end with one of the letters in the set aAdifeEgGosxX%. These letters denote the following types:

• d: integer

Eg a more general example

    sprintf("I am %10d years old", 25)
[1] "I am         25 years old"
          ^^^^^^^^^^

try unpacking in one variable,

python will handle it as a list,

then unpack from the list

def returnATupleWithThreeValues():
    return (1,2,3)
a = returnATupleWithThreeValues() # a is a list (1,2,3)
print a[0] # list[0] = 1
print a[1] # list[1] = 2
print a[2] # list[2] = 3

The steps mentioned by Jason are very good and should work. There is a little twist with SQL Developer, though. It caches the connection specifications (host, service name, port) the first time it reads the tnsnames.ora file. Then, it does not invalidate the specs when the original entry is removed from the tnsname.ora file. The cache persists even after SQL Developer has been terminated and restarted. This is not such an illogical way of handling the situation. Even if a tnsnames.ora file is temporarily unavailable, SQL Developer can still make the connection as long as the original specifications are still true. The problem comes with their next little twist. SQL Developer treats service names in the tnsnames.ora file as case-sensitive values when resolving the connection. So if you used to have an entry name ABCD.world in the file and you replaced it with an new entry named abcd.world, SQL Developer would NOT update its connection specs for ABCD.world - it will treat abcd.world as a different connection altogether. Why am I not surprised that an Oracle product would treat as case-sensitive the contents of an oracle-developed file format that is expressly case-insensitive?

It's an awesome detailed reply by Janusz. But just for the sake of people who are coming to this page for answers, the easier way is at http://android-holo-colors.com/ (dead link) linked from Android Asset Studio

However, I highly recommend everybody to read the reply from Janusz as it will make understanding clearer. Use the tool to do stuffs real quick

Try this server control which inherits directly from CheckBoxList (free, open source): http://dropdowncheckboxes.codeplex.com/

To get the id of the parent div:

$(buttonSelector).parents('div:eq(0)').attr('id');

Also, you can refactor your code quite a bit:

$('button').click( function() {
 var correct = Number($(this).attr('rel'));
 validate(Number($(this).siblings('input').val()), correct);
 $(this).parents('div:eq(0)').html(feedback);
});

Now there is no need for a button-class

explanation
eq(0), means that you will select one element from the jQuery object, in this case element 0, thus the first element. http://docs.jquery.com/Selectors/eq#index
$(selector).siblings(siblingsSelector) will select all siblings (elements with the same parent) that match the siblingsSelector http://docs.jquery.com/Traversing/siblings#expr
$(selector).parents(parentsSelector) will select all parents of the elements matched by selector that match the parent selector. http://docs.jquery.com/Traversing/parents#expr
Thus: $(selector).parents('div:eq(0)'); will match the first parent div of the elements matched by selector.

You should have a look at the jQuery docs, particularly selectors and traversing:

• http://docs.jquery.com/
• http://docs.jquery.com/Selectors
• http://docs.jquery.com/Traversing

This is an old post however, one alternative is to use the command options:

ftp -n -s:ftpcmd.txt

the -n will suppress the initial login and then the file contents would be: (replace the 127.0.0.1 with your FTP site url)

open 127.0.0.1
user myFTPuser myftppassword
other commands here...

This avoids the user/password on separate lines

While dbenham's answer is pretty good, relying on IF DEFINED can get you in loads of trouble if the variable you're checking isn't an environment variable. Script variables don't get this special treatment.

While this might seem like some ludicrous undocumented BS, doing a simple shell query of IF with IF /? reveals that,

The DEFINED conditional works just like EXIST except it takes an environment variable name and returns true if the environment variable is defined.

In regards to answering this question, is there a reason to not just use a simple flag after a series of evaluations? That seems the most flexible OR check to me, both in regards to underlying logic and readability. For example:

Set Evaluated_True=false

IF %condition_1%==true (Set Evaluated_True=true)
IF %some_string%=="desired result" (Set Evaluated_True=true)
IF %set_numerical_variable% EQ %desired_numerical_value% (Set Evaluated_True=true)

IF %Evaluated_True%==true (echo This is where you do your passing logic) ELSE (echo This is where you do your failing logic)

Obviously, they can be any sort of conditional evaluation, but I'm just sharing a few examples.

If you wanted to have it all on one line, written-wise, you could just chain them together with && like:

Set Evaluated_True=false

IF %condition_1%==true (Set Evaluated_True=true) && IF %some_string%=="desired result" (Set Evaluated_True=true) && IF %set_numerical_variable% EQ %desired_numerical_value% (Set Evaluated_True=true)

IF %Evaluated_True%==true (echo This is where you do your passing logic) ELSE (echo This is where you do your failing logic)

event.preventDefault()

Doesn't work in all browsers. Instead you could return false in OnClick event.

onClick="toggle_it('tr1');toggle_it('tr2'); return false;">

Not sure if this is the best way, but I tested in IE, FF and Chrome and its working fine.

df = pd.DataFrame({'movie': ['thg', 'thg', 'mol', 'mol', 'lob', 'lob'],'rating': [3., 4., 5., np.nan, np.nan, np.nan],'name': ['John','James', np.nan, np.nan, np.nan,np.nan]})

for col in df.columns:
    df = df[~pd.isnull(df[col])]

Just a tip.. Temporary tables in Oracle are different to SQL Server. You create it ONCE and only ONCE, not every session. The rows you insert into it are visible only to your session, and are automatically deleted (i.e., TRUNCATE, not DROP) when you end you session ( or end of the transaction, depending on which "ON COMMIT" clause you use).

A PHP Based Solution for search entire table ! Search string is $string . This is generic and will work with all the tables with any number of fields

$sql="SELECT * from client_wireless";
$sql_query=mysql_query($sql);
$logicStr="WHERE ";
$count=mysql_num_fields($sql_query);
for($i=0 ; $i < mysql_num_fields($sql_query) ; $i++){
 if($i == ($count-1) )
$logicStr=$logicStr."".mysql_field_name($sql_query,$i)." LIKE '%".$string."%' ";
else
$logicStr=$logicStr."".mysql_field_name($sql_query,$i)." LIKE '%".$string."%' OR ";
}
// start the search in all the fields and when a match is found, go on printing it .
$sql="SELECT * from client_wireless ".$logicStr;
//echo $sql;
$query=mysql_query($sql);

I get the same error after i made changes with my data context. But i encounter something i am unfamiliar with. I get used to publish my files manually. Normally when i do that there is no App_Code folder appears in publishing folder. Bu i started to use VS 12 publishing which directly publishes with your assistance to the web server. And then i get the error about being precompiled application. Then i delete app_code folder it worked. But then it gave me the Data Context error that you are getting. So i just deleted all the files and run the publish again with no file restrictions (every folder & file will be published) then it worked like a charm.

In case others have the same issue:

I had a similar error happening. turned out I was wrapping several SQL statements in a transactions, where one of them executed on a linked server (Merge statement in an EXEC(...) AT Server statement). I resolved the issue by opening a separate connection to the linked server, encapsulating that statement in a try...catch then abort the transaction on the original connection in case the catch is tripped.

REST is not a specific web service but a design concept (architecture) for managing state information. The seminal paper on this was Roy Thomas Fielding's dissertation (2000), "Architectural Styles and the Design of Network-based Software Architectures" (available online from the University of California, Irvine).

First read Ryan Tomayko's post How I explained REST to my wife; it's a great starting point. Then read Fielding's actual dissertation. It's not that advanced, nor is it long (six chapters, 180 pages)! (I know you kids in school like it short).

EDIT: I feel it's pointless to try to explain REST. It has so many concepts like scalability, visibility (stateless) etc. that the reader needs to grasp, and the best source for understanding those are the actual dissertation. It's much more than POST/GET etc.

Try it from

You actually can use sed to do it, provided it is GNU sed.

... | sed 's/match/command \0/e'

How it works:

1. Substitute match with command match
2. On substitution execute command
3. Replace substituted line with command output.

ok just my two cents, use a is string method:

public static boolean isString(Object thing) {
    return thing instanceof String;
}

public void someMethod(Object thing){
    if (!isString(thing)) {
        return null;
    }
    log.debug("my thing is valid");
}

Another way to think of it is to calculate the unit vector for a given direction and then apply a 90 degree counterclockwise rotation to get the normal vector.

The matrix representation of the general 2D transformation looks like this:

x' = x cos(t) - y sin(t)
y' = x sin(t) + y cos(t)

where (x,y) are the components of the original vector and (x', y') are the transformed components.

If t = 90 degrees, then cos(90) = 0 and sin(90) = 1. Substituting and multiplying it out gives:

x' = -y
y' = +x

Same result as given earlier, but with a little more explanation as to where it comes from.

For me, I had to remove the intellij internal sdk and started to use my local sdk. When I started to use the internal, the error was gone.

Something I ran into that wasn't apparent from a first reading of the tutorial and docs was the idea of multicasting.

Make sure you're aware that by default, multiple subscriptions will trigger multiple executions in an Observable. Multiple subscriptions to a single HTTP call Observable will trigger multiple identical HTTP calls unless you .share() (enable multicasting).

A promise forces you to deal with one thing at a time, unwrap its data, handle exceptions, has language support for cool things like async/await, and is pretty barebones otherwise.

An Observable has lots of bells and whistles, but you need to understand the power you're working with or it can be misused.

This is old thread, but I have find new answer on https://css-tricks.com/NetMag/FluidWidthVideo/Article-FluidWidthVideo.php

The problem with previous solution is that you need to have special div around video code, which is not suitable for most uses. So here is JavaScript solution without special div.

// Find all YouTube videos - RESIZE YOUTUBE VIDEOS!!!
var $allVideos = $("iframe[src^='https://www.youtube.com']"),

// The element that is fluid width
$fluidEl = $("body");

// Figure out and save aspect ratio for each video
$allVideos.each(function() {

    $(this)
    .data('aspectRatio', this.height / this.width)

    // and remove the hard coded width/height
    .removeAttr('height')
    .removeAttr('width');

});

// When the window is resized
$(window).resize(function() {

    var newWidth = $fluidEl.width();

    // Resize all videos according to their own aspect ratio
    $allVideos.each(function() {

        var $el = $(this);
        $el
        .width(newWidth)
        .height(newWidth * $el.data('aspectRatio'));

    });

// Kick off one resize to fix all videos on page load
}).resize();

// END RESIZE VIDEOS

You can use clientWidth or offsetWidth Mozilla developer network reference

It would be like:

document.getElementById("yourDiv").clientWidth; // returns number, like 728

or with borders width :

document.getElementById("yourDiv").offsetWidth; // 728 + borders width

    #bold{_x000D_
      font-weight: bold;_x000D_
    }_x000D_
    #custom{_x000D_
      font-weight: 200;_x000D_
    }

<body>_x000D_
  <p id="bold"> here is a bold text using css </p>_x000D_
  <p id="custom"> here is a custom bold text using css </p>_x000D_
</body>

I hope it's worked

Below, code snippet, will help you in understanding the mutex-lock-unlock concept. Attempt dry-run on the code. (further by varying the wait-time and process-time, you can build you understanding).

Code for your reference:

If you need to handle values that cannot be converted separately, you can use this method:

try {
    $valueToUse = trim($stringThatMightBeNumeric) + 0;
} catch (\Throwable $th) {
    // bail here if you need to
}

Remember that

log(n!) = log(1) + log(2) + ... + log(n-1) + log(n)

You can get the upper bound by

log(1) + log(2) + ... + log(n) <= log(n) + log(n) + ... + log(n)
                                = n*log(n)

And you can get the lower bound by doing a similar thing after throwing away the first half of the sum:

log(1) + ... + log(n/2) + ... + log(n) >= log(n/2) + ... + log(n) 
                                       = log(n/2) + log(n/2+1) + ... + log(n-1) + log(n)
                                       >= log(n/2) + ... + log(n/2)
                                        = n/2 * log(n/2) 

Use the Instr function

Dim pos As Integer

pos = InStr("find the comma, in the string", ",")

will return 15 in pos

If not found it will return 0

If you need to find the comma with an excel formula you can use the =FIND(",";A1) function.

Notice that if you want to use Instr to find the position of a string case-insensitive use the third parameter of Instr and give it the const vbTextCompare (or just 1 for die-hards).

Dim posOf_A As Integer

posOf_A = InStr(1, "find the comma, in the string", "A", vbTextCompare)

will give you a value of 14.

Note that you have to specify the start position in this case as stated in the specification I linked: The start argument is required if compare is specified.

On my Macintosh systems, I find that "Adobe Reader" does a reasonably good job. I created an alias on my Desktop that points to the "Adobe Reader.app", and all I do is drop a pdf-file on the alias, which makes it the active document in Adobe Reader, and then from the File-menu, I choose "Save as Text...", give it a name and where to save it, click "Save", and I'm done.

If they are separate classes you can do something like the following:

class A
{
    private $name;

    public function __construct()
    {
        $this->name = 'Some Name';
    }

    public function getName()
    {
        return $this->name;
    }
}

class B
{
    private $a;

    public function __construct(A $a)
    {
        $this->a = $a;
    }

    function getNameOfA()
    {
        return $this->a->getName();
    }
}

$a = new A();
$b = new B($a);

$b->getNameOfA();

What I have done in this example is first create a new instance of the A class. And after that I have created a new instance of the B class to which I pass the instance of A into the constructor. Now B can access all the public members of the A class using $this->a.

Also note that I don't instantiate the A class inside the B class because that would mean I tighly couple the two classes. This makes it hard to:

1. unit test your B class
2. swap out the A class for another class

You can use relative paths. Try __FILE__. This is a PHP constant which always returns the path/filename of the script it is in. So, in soap.php, you could do:

include dirname(__FILE__).'/../inc/include.php';

The full path and filename of the file. If used inside an include, the name of the included file is returned. Since PHP 4.0.2, __FILE__ always contains an absolute path with symlinks resolved whereas in older versions it contained relative path under some circumstances. (source)

Another solution would be to set an include path in your httpd.conf or an .htaccess file.

The syntax is wrong. The typedef should be removed.

This acronym might help you to remember the ASP.NET life cycle stages which I wrote about in the below blog post.

You may try this

git clone --single-branch --branch <branchname> host:/dir.git

The answers didn't work for me with postgresql 9.1+

This is what I had to do (you can check more in the manual here)

UPDATE schema.TableA as A
SET "columnA" = "B"."columnB"
FROM schema.TableB as B
WHERE A.id = B.id;

You can omit the schema, if you are using the default schema for both tables.

You can also do like this:

template <typename T>
class make_vector {
public:
  typedef make_vector<T> my_type;
  my_type& operator<< (const T& val) {
    data_.push_back(val);
    return *this;
  }
  operator std::vector<T>() const {
    return data_;
  }
private:
  std::vector<T> data_;
};

And use it like this:

std::vector<int> v = make_vector<int>() << 1 << 2 << 3;

https://github.com/mattt/TTTAttributedLabel

That's definitely what you need. You can also apply attributes for your label, like underline, and apply different colors to it. Just check the instructions for clickable urls.

Mainly, you do something like the following:

NSRange range = [label.text rangeOfString:@"me"];
[label addLinkToURL:[NSURL URLWithString:@"http://github.com/mattt/"] withRange:range]; // Embedding a custom link in a substring

If you want to lock the main view of your app to portrait, but want to open popup views in landscape, and you are using tabBarController as rootViewController as I am, you can use this code on your AppDelegate.

AppDelegate.h

@interface AppDelegate : UIResponder <UIApplicationDelegate, UITabBarControllerDelegate>

@property (strong, nonatomic) UIWindow *window;
@property (strong, nonatomic) UITabBarController *tabBarController;

@end

AppDelegate.m

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];

    // Create a tab bar and set it as root view for the application
    self.tabBarController = [[UITabBarController alloc] init];
    self.tabBarController.delegate = self;
    self.window.rootViewController = self.tabBarController;

    ...
}

- (NSUInteger)tabBarControllerSupportedInterfaceOrientations:(UITabBarController *)tabBarController
{
    return UIInterfaceOrientationMaskPortrait;
}

- (UIInterfaceOrientation)tabBarControllerPreferredInterfaceOrientationForPresentation:(UITabBarController *)tabBarController
{
    return UIInterfaceOrientationPortrait;
}

It works very well.

In your viewController you want to be presented in landscape, you simply use the following:

- (NSUInteger)supportedInterfaceOrientations {
    return UIInterfaceOrientationMaskLandscape;
}

- (BOOL)shouldAutorotate {
    return YES;
}

Let me just mention this here: the Java

try 
{
...
}
catch (Exception e)
{
...
}

may NOT catch all exceptions! I've actually had this sort of thing happen before, and it's insantiy-provoking; Exception derives from Throwable. So literally, to catch everything, you DON'T want to catch Exceptions; you want to catch Throwable.

I know it sounds nitpicky, but when you've spent several days trying to figure out where the "uncaught exception" came from in code that was surrounded by a try ... catch (Exception e)" block comes from, it sticks with you.

Had this same issue but there was not stack thread. We deleted the job by using this snippet in the Jenkins Console. Replace jobname and buil dnumber with yours.

def jobname = "Main/FolderName/BuildDefinition"
def buildnum = 6
Jenkins.instance.getItemByFullName(jobname).getBuildByNumber(buildnum).delete(); 

You can use sed:

sed 's/,$//' file > file.nocomma

and to remove whatever last character:

sed 's/.$//' file > file.nolast

Whatever I understood from my learning and what I think it is is here. I am Quoting some part from a book i learnt this things. Nexus Repository Manager and Nexus Repository Manager OSS started as a repository manager supporting the Maven repository format. While it supports many other repository formats now, the Maven repository format is still the most common and well supported format for build and provisioning tools running on the JVM and beyond. This chapter shows example configurations for using the repository manager with Apache Maven and a number of other tools. The setups take advantage of merging many repositories and exposing them via a repository group. Setting this up is documented in the chapter in addition to the configuration used by specific tools.

From a Collection, another way you could do it would be:

$collection->pluck('id')->toArray()

This will return an indexed array, perfectly usable by laravel in a whereIn() query, for instance.

ListViewItem.IsSelected = true;
ListViewItem.Focus();

I don't know what's wrong with yours but one thing for sure is you need to call AES_set_decrypt_key() before decrypting the message. Also don't try to print out as %s because the encrypted message isn't composed by ascii characters anymore.. For example:

static const unsigned char key[] = {
    0x00, 0x11, 0x22, 0x33, 0x44, 0x55, 0x66, 0x77,
    0x88, 0x99, 0xaa, 0xbb, 0xcc, 0xdd, 0xee, 0xff,
    0x00, 0x01, 0x02, 0x03, 0x04, 0x05, 0x06, 0x07,
    0x08, 0x09, 0x0a, 0x0b, 0x0c, 0x0d, 0x0e, 0x0f
};

int main()
{
    unsigned char text[]="hello world!";
    unsigned char enc_out[80];
    unsigned char dec_out[80];

    AES_KEY enc_key, dec_key;

    AES_set_encrypt_key(key, 128, &enc_key);
    AES_encrypt(text, enc_out, &enc_key);      

    AES_set_decrypt_key(key,128,&dec_key);
    AES_decrypt(enc_out, dec_out, &dec_key);

    int i;

    printf("original:\t");
    for(i=0;*(text+i)!=0x00;i++)
        printf("%X ",*(text+i));
    printf("\nencrypted:\t");
    for(i=0;*(enc_out+i)!=0x00;i++)
        printf("%X ",*(enc_out+i));
    printf("\ndecrypted:\t");
    for(i=0;*(dec_out+i)!=0x00;i++)
        printf("%X ",*(dec_out+i));
    printf("\n");

    return 0;
} 

U1: your key is 192 bit isn't it...

I find the following link quite useful

http://blog.hubspot.com/marketing/calendar-invites-ical-outlook-google

public static double addDoubles(double a, double b) {
        BigDecimal A = new BigDecimal(a + "");
        BigDecimal B = new BigDecimal(b + "");
        return A.add(B).setScale(2, BigDecimal.ROUND_HALF_UP).doubleValue();
    }

Perhaps is way too late to respond but, make sure your session is initialized before destroying it.

session_start() ;
session_destroy() ;

i.e. you cannot destroy a session in logout.php if you initialized your session in index.php. You must start the session in logout.php before destroying it.

This is because Keypress event is fired before the new character is added. Use 'keyup' event instead,which will work perfectly in your situation.

$(document).ready(function() {
    $("#dSuggest").keyup(function() {
        var dInput = $('input:text[name=dSuggest]').val();
        console.log(dInput);
        $(".dDimension:contains('" + dInput + "')").css("display","block");
    });
});

I want to add to this, if you have many textboxes and you have to do the same thing on their keyup event you can simply give them a common css class(eg commoncss) and apply keyup event like this.

$(document).ready(function() {
    $(".commoncss").keyup(function() {
        //your code
    });
});

this will greatly reduce you code as you don't have to apply keyup event by id for each textboxes.

Hi you can do it this way

    temp = sp.coo_matrix((data, (row, col)), shape=(3, 59))
    temp1 = temp.tocsr()

    #Cosine similarity
    row_sums = ((temp1.multiply(temp1)).sum(axis=1))
    rows_sums_sqrt = np.array(np.sqrt(row_sums))[:,0]
    row_indices, col_indices = temp1.nonzero()
    temp1.data /= rows_sums_sqrt[row_indices]
    temp2 = temp1.transpose()
    temp3 = temp1*temp2

This has already been answered here: How do I translate a ISO 8601 datetime string into a Python datetime object?

d.weekday()

I understand that CASTing to FLOAT is not allowed in MySQL and will raise an error when you attempt to CAST(1 AS float) as stated at MySQL dev.

The workaround to this is a simple one. Just do

(1 + 0.0)

Then use ROUND to achieve a specific number of decimal places like

ROUND((1+0.0)/(2+0.0), 3)

The above SQL divides 1 by 2 and returns a float to 3 decimal places, as in it would be 0.500.

One can CAST to the following types: binary, char, date, datetime, decimal, json, nchar, signed, time, and unsigned.

You need to set useaccessibleheader attribute of the gridview to true and also then also specify a TableSection to be a header after calling the DataBind() method on you GridView object. So if your grid view is mygv

mygv.UseAccessibleHeader = True
mygv.HeaderRow.TableSection = TableRowSection.TableHeader

This should result in a proper formatted grid with thead and tbody tags

If you're seeing this error and you just upgraded to Android Studio 2.2+ you need to update your JDK in "Project Structure" options.

On OSX, this is found under File > Project Structure > SDK. Or from the welcome screen in Configure > Project Defaults > Project Structure.

Select the Use the embedded JDK (recommended) option instead of using your own JDK.

Google's docs aren't yet updated to reflect this change. See: http://tools.android.com/tech-docs/configuration/osx-jdk

To get this working for Calabash automated tests

There is a pull request up to fix the issue of xcode 12 not working with calabash https://github.com/calabash/run_loop/pull/757

A temporary solution is to use this WIP branch, although it is not great to have to use this as it is a draft PR. Xcode 12 support for Calabash will hopefully come in the future.

Change in your Gemfile

gem "run_loop"

to

gem 'run_loop', git: 'https://github.com/calabash/run_loop.git', branch: 'xcode_14_support'

<?php
$file = "http://example.com/go.exe"; 

header("Content-Description: File Transfer"); 
header("Content-Type: application/octet-stream"); 
header("Content-Disposition: attachment; filename=\"". basename($file) ."\""); 

readfile ($file);
exit(); 
?>

Or, when the file is not openable with the browser, you can just use the Location header:

<?php header("Location: http://example.com/go.exe"); ?>

I'm surprised nobody has mentioned pathlib's with_name. This solution works with multiple extensions (i.e. it replaces all of the extensions.)

import pathlib

p = pathlib.Path('/some/path/somefile.txt')
p = p.with_name(p.stem).with_suffix('.jpg')

What works for me, let's say you have branch1 and you wanna merge it into branch2.

You open git command line go to root folder of branch2 and type:

git checkout branch1
git pull branch1
git checkout branch2
git merge branch1
git push

If you have comflicts you don't need to do git push, but first solve the conflits and then push.

Different timeouts mean different things. When you're working on the client.. you're probably looking mostly at the SendTimeout - check this reference - wonderful and relevant explanation: http://social.msdn.microsoft.com/Forums/en-US/wcf/thread/84551e45-19a2-4d0d-bcc0-516a4041943d/

It says:

Brief summary of binding timeout knobs...

Client side:

SendTimeout is used to initialize the OperationTimeout, which governs the whole interaction for sending a message (including receiving a reply message in a request-reply case).  This timeout also applies when sending reply messages from a CallbackContract method.
OpenTimeout and CloseTimeout are used when opening and closing channels (when no explicit timeout value is passed).
ReceiveTimeout is not used.

Server side:

Send, Open, and Close Timeout same as on client (for Callbacks).
ReceiveTimeout is used by ServiceFramework layer to initialize the session-idle timeout.

Contrary to Martin's answer, casting to int (or ignoring the warning) isn't always safe even if you know your array doesn't have more than 2^31-1 elements. Not when compiling for 64-bit.

For example:

NSArray *array = @[@"a", @"b", @"c"];

int i = (int) [array indexOfObject:@"d"];
// indexOfObject returned NSNotFound, which is NSIntegerMax, which is LONG_MAX in 64 bit.
// We cast this to int and got -1.
// But -1 != NSNotFound. Trouble ahead!

if (i == NSNotFound) {
    // thought we'd get here, but we don't
    NSLog(@"it's not here");
}
else {
    // this is what actually happens
    NSLog(@"it's here: %d", i);

    // **** crash horribly ****
    NSLog(@"the object is %@", array[i]);
}

If the types of the parameters are all the same (varchar2 for example), you can have a package like this which will do the following:

CREATE OR REPLACE PACKAGE testuser.test_pkg IS

   TYPE assoc_array_varchar2_t IS TABLE OF VARCHAR2(4000) INDEX BY BINARY_INTEGER;

   PROCEDURE your_proc(p_parm IN assoc_array_varchar2_t);

END test_pkg;

CREATE OR REPLACE PACKAGE BODY testuser.test_pkg IS

   PROCEDURE your_proc(p_parm IN assoc_array_varchar2_t) AS
   BEGIN
      FOR i IN p_parm.first .. p_parm.last
      LOOP
         dbms_output.put_line(p_parm(i));
      END LOOP;

   END;

END test_pkg;

Then, to call it you'd need to set up the array and pass it:

DECLARE
  l_array testuser.test_pkg.assoc_array_varchar2_t;
BEGIN
  l_array(0) := 'hello';
  l_array(1) := 'there';  

  testuser.test_pkg.your_proc(l_array);
END;
/

Most likely the remote repository doesn't exist or you have added the wrong one.

You have to first remove the origin and re-add it:

git remote remove origin
git remote add origin https://github.com/username/repository

Give each input a name attribute. Only the clicked input's name attribute will be sent to the server.

<input type="submit" name="publish" value="Publish">
<input type="submit" name="save" value="Save">

And then

<?php
    if (isset($_POST['publish'])) {
        # Publish-button was clicked
    }
    elseif (isset($_POST['save'])) {
        # Save-button was clicked
    }
?>

Edit: Changed value attributes to alt. Not sure this is the best approach for image buttons though, any particular reason you don't want to use input[type=image]?

Edit: Since this keeps getting upvotes I went ahead and changed the weird alt/value code to real submit inputs. I believe the original question asked for some sort of image buttons but there are so much better ways to achieve that nowadays instead of using input[type=image].

The best way is probably trying to open it, using just opendir() for instance.

Note that it's always best to try to use a filesystem resource, and handling any errors occuring because it doesn't exist, rather than just checking and then later trying. There is an obvious race condition in the latter approach.

Assume scenario where swimmers swim in swimming pool in the areas reserved for them.what happens if swimmers swim other than the areas reserved for them,the whole thing would become mess.similarly iis uses application pools to seperate one process from another.

There is definitly a problem with the destination folder path.

Your above error message says, it wants to put the contents to a file in the directory /files/grantapps/, which would be beyond your vhost, but somewhere in the system (see the leading absolute slash )

You should double check:

• Is the directory /home/username/public_html/files/grantapps/ really present.
• Contains your loop and your file_put_contents-Statement the absolute path /home/username/public_html/files/grantapps/

Committing package-lock.json to the source code version control means that the project will use a specific version of dependencies that may or may not match those defined in package.json. while the dependency has a specific version without any Caret (^) and Tilde (~) as you can see, that's mean the dependency will not be updated to the most recent version. and npm install will pick up the same version as well as we need it for our current version of Angular.

Note : package-lock.json highly recommended to commit it IF I added any Caret (^) and Tilde (~) to the dependency to be updated during the CI.

From ggplot2 2.0.0 you can use the margin = argument of element_text() to change the distance between the axis title and the numbers. Set the values of the margin on top, right, bottom, and left side of the element.

ggplot(mpg, aes(cty, hwy)) + geom_point()+
  theme(axis.title.y = element_text(margin = margin(t = 0, r = 20, b = 0, l = 0)))

margin can also be used for other element_text elements (see ?theme), such as axis.text.x, axis.text.y and title.

addition

in order to set the margin for axis titles when the axis has a different position (e.g., with scale_x_...(position = "top"), you'll need a different theme setting - e.g. axis.title.x.top. See https://github.com/tidyverse/ggplot2/issues/4343.

I wrote two programs:

int main(){return 0;}

and

#include <stdlib.h>
int main(){exit(0)}

After executing gcc -S -O1. Here what I found watching at assembly (only important parts):

main:
    movl    $0, %eax    /* setting return value */
    ret                 /* return from main */

and

main:
    subq    $8, %rsp    /* reserving some space */
    movl    $0, %edi    /* setting return value */
    call    exit        /* calling exit function */
                        /* magic and machine specific wizardry after this call */

So my conclusion is: use return when you can, and exit() when you need.

A lot of other answers are focusing on a pattern that does work, but their explanations aren't really very thorough as to why your current code doesn't work.

Your code, for reference:

function funcName() {
    alert("test");
}

var func = funcName();
var run = setInterval("func",10000)

Let's break this up into chunks. Your function funcName is fine. Note that when you call funcName (in other words, you run it) you will be alerting "test". But notice that funcName() -- the parentheses mean to "call" or "run" the function -- doesn't actually return a value. When a function doesn't have a return value, it defaults to a value known as undefined.

When you call a function, you append its argument list to the end in parentheses. When you don't have any arguments to pass the function, you just add empty parentheses, like funcName(). But when you want to refer to the function itself, and not call it, you don't need the parentheses because the parentheses indicate to run it.

So, when you say:

var func = funcName();

You are actually declaring a variable func that has a value of funcName(). But notice the parentheses. funcName() is actually the return value of funcName. As I said above, since funcName doesn't actually return any value, it defaults to undefined. So, in other words, your variable func actually will have the value undefined.

Then you have this line:

var run = setInterval("func",10000)

The function setInterval takes two arguments. The first is the function to be ran every so often, and the second is the number of milliseconds between each time the function is ran.

However, the first argument really should be a function, not a string. If it is a string, then the JavaScript engine will use eval on that string instead. So, in other words, your setInterval is running the following JavaScript code:

func
// 10 seconds later....
func
// and so on

However, func is just a variable (with the value undefined, but that's sort of irrelevant). So every ten seconds, the JS engine evaluates the variable func and returns undefined. But this doesn't really do anything. I mean, it technically is being evaluated every 10 seconds, but you're not going to see any effects from that.

The solution is to give setInterval a function to run instead of a string. So, in this case:

var run = setInterval(funcName, 10000);

Notice that I didn't give it func. This is because func is not a function in your code; it's the value undefined, because you assigned it funcName(). Like I said above, funcName() will call the function funcName and return the return value of the function. Since funcName doesn't return anything, this defaults to undefined. I know I've said that several times now, but it really is a very important concept: when you see funcName(), you should think "the return value of funcName". When you want to refer to a function itself, like a separate entity, you should leave off the parentheses so you don't call it: funcName.

So, another solution for your code would be:

var func = funcName;
var run = setInterval(func, 10000);

However, that's a bit redundant: why use func instead of funcName?

Or you can stay as true as possible to the original code by modifying two bits:

var func = funcName;
var run = setInterval("func()", 10000);

In this case, the JS engine will evaluate func() every ten seconds. In other words, it will alert "test" every ten seconds. However, as the famous phrase goes, eval is evil, so you should try to avoid it whenever possible.

Another twist on this code is to use an anonymous function. In other words, a function that doesn't have a name -- you just drop it in the code because you don't care what it's called.

setInterval(function () {
    alert("test");
}, 10000);

In this case, since I don't care what the function is called, I just leave a generic, unnamed (anonymous) function there.

Use

[A-Z]?

to make the letter optional. {1} is redundant. (Of course you could also write [A-Z]{0,1} which would mean the same, but that's what the ? is there for.)

You could improve your regex to

^([0-9]{5})+\s+([A-Z]?)\s+([A-Z])([0-9]{3})([0-9]{3})([A-Z]{3})([A-Z]{3})\s+([A-Z])[0-9]{3}([0-9]{4})([0-9]{2})([0-9]{2})

And, since in most regex dialects, \d is the same as [0-9]:

^(\d{5})+\s+([A-Z]?)\s+([A-Z])(\d{3})(\d{3})([A-Z]{3})([A-Z]{3})\s+([A-Z])\d{3}(\d{4})(\d{2})(\d{2})

But: do you really need 11 separate capturing groups? And if so, why don't you capture the fourth-to-last group of digits?

There was a project that used linked files. I needed to add the method.cs file to that project as a linked file as well, since the FBlock.cs file was there. I've never heard of linked files before, I didn't even know that was possible.

For every system that support relative URI resolution, both relative and absolute URIs do serve the same goal: referencing. And they can be used interchangeably. So you could decide in each case differently. Technically, they provide the same referencing.

To be precise, with each relative URI there already is an absolute URI. And that's the base-URI that relative URI is resolved against. So a relative URI is actually a feature on top of absolute URIs.

And that's also why with relative URIs you can do more as with an absolute URI alone - this is especially important for static websites which otherwise couldn't be as flexible to maintain as compared to absolute URIs.

These positive effects of relative URI resolution can be exploited for dynamic web-application development as well. The inflexibility absolute URIs do introduce are also easier to cope up with, in a dynamic environment, so for some developers that are unsure about URI resolution and how to properly implement and manage it (not that it's always easy) do often opt into using absolute URIs in a dynamic part of a website as they can introduce other dynamic features (e.g. configuration variable containing the URI prefix) so to work around the inflexibility.

So what is the benefit then in using absolute URIs? Technically there ain't, but one I'd say: Relative URIs are more complex because they need to be resolved against the so called absolute base-URI. Even the resolution is strictly define since years, you might run over a client that has a mistake in URI resolution. As absolute URIs do not need any resolution, using absolute URIs have no risk to run into faulty client behaviour with relative URI resolution. So how high is that risk actually? Well, it's very rare. I only know about one Internet browser that had an issue with relative URI resolution. And that was not generally but only in a very (obscure) case.

Next to the HTTP client (browser) it's perhaps more complex for an author of hypertext documents or code as well. Here the absolute URI has the benefit that it is easier to test, as you can just enter it as-is into your browsers address bar. However, if it's not just your one-hour job, it's most often of more benefit to you to actually understand absolute and relative URI handling so that you can actually exploit the benefits of relative linking.

Solution: In order to increase your buffer history on iterm bash terminal you've got two options:

Go to iterm -> Preferences -> Profiles -> Terminal Tab -> Scrollback Buffer (section)

Option 1. select the checkbox Unlimited scrollback

Option 2. type the selected Scrollback lines numbers you'd like your terminal buffer to cache (See image below)

It depends. The standard only demands that it is large enough to hold all values, so formally an enum like enum foo { zero, one, two }; needs to only be one byte large. However most implementations make those enums as large as ints (that's faster on modern hardware; moreover it's needed for compatibility with C where enums are basically glorified ints). Note however that C++ allows enums with initializers outside of the int range, and for those enums the size will of course also be larger. For example, if you have enum bar { a, b = 1LL << 35 }; then your enum will be larger than 32 bits (most likely 64 bits) even on a system with 32 bit ints (note that in C that enum would not be allowed).

I came up with this noob simple version

def ip_checkv4(ip):
        parts=ip.split(".")
        if len(parts)<4 or len(parts)>4:
            return "invalid IP length should be 4 not greater or less than 4"
        else:
            while len(parts)== 4:
                a=int(parts[0])
                b=int(parts[1])
                c=int(parts[2])
                d=int(parts[3])
                if a<= 0 or a == 127 :
                    return "invalid IP address"
                elif d == 0:
                    return "host id  should not be 0 or less than zero " 
                elif a>=255:
                    return "should not be 255 or greater than 255 or less than 0 A"
                elif b>=255 or b<0: 
                    return "should not be 255 or greater than 255 or less than 0 B"
                elif c>=255 or c<0:
                    return "should not be 255 or greater than 255 or less than 0 C"
                elif d>=255 or c<0:
                    return "should not be 255 or greater than 255 or less than 0 D"
                else:
                    return "Valid IP address ", ip

    p=raw_input("Enter IP address")
    print ip_checkv4(p)

One difference observed (Python27):

os.environ raises an exception if the environmental variable does not exist. os.getenv does not raise an exception, but returns None

None of these answers worked for me.

I had to remove all deployed java web app:

• Windows/Show View/Other...
• Go the the Server folder and select "Servers"
• Right-click on the J2EE Preview at localhost
• Click to Add and Remove... Click Remove all

Then run the project on the server

The Error is gone!

You will have to stop the server before deploying another project because it will not be found by the server. Otherwise you will get a 404 error

This may have been answered before: Python URLLib / URLLib2 POST.

Your server is likely performing a 302 redirect from http://myserver/post_service to http://myserver/post_service/. When the 302 redirect is performed, the request changes from POST to GET (see Issue 1401). Try changing url to http://myserver/post_service/.

Another important difference, that wasn't mentioned in any answer above, is that there is no equality operator for json type, but there is one for jsonb.

This means that you can't use DISTINCT keyword when selecting this json-type and/or other fields from a table (you can use DISTINCT ON instead, but it's not always possible because of cases like this).

Another option is to add style to div

<div style="position: absolute; height:somePercentage%; overflow:auto(or other overflow value)">
 //to be scrolled 
</div>

And it means that an element is positioned relative to the nearest positioned ancestor.

Here is a swift version:

struct iOSVersion {
    static let SYS_VERSION_FLOAT = (UIDevice.currentDevice().systemVersion as NSString).floatValue
    static let iOS7 = (Version.SYS_VERSION_FLOAT < 8.0 && Version.SYS_VERSION_FLOAT >= 7.0)
    static let iOS8 = (Version.SYS_VERSION_FLOAT >= 8.0 && Version.SYS_VERSION_FLOAT < 9.0)
    static let iOS9 = (Version.SYS_VERSION_FLOAT >= 9.0 && Version.SYS_VERSION_FLOAT < 10.0)
}

Usage:

if iOSVersion.iOS8 {
    //Do iOS8 code here
}

As sort method converts Array elements into string. So, below way also works fine with decimal numbers with array elements.

let productPrices = [10.33, 2.55, 1.06, 5.77];
console.log(productPrices.sort((a,b)=>a-b));

And gives you the expected result.

This is the wrong question to be asking. It's all too easy to focus on git's warts and formulate an argument about why subversion is ostensibly better, at least for some use cases. The fact that git was originally designed as a low-level version control construction set and has a baroque linux-developer-oriented interface makes it easier for the holy wars to gain traction and perceived legitimacy. Git proponents bang the drum with millions of workflow advantages, which svn guys proclaim unnecessary. Pretty soon the whole debate is framed as centralized vs distributed, which serves the interests of the enterprise svn tool community. These companies, which typically put out the most convincing articles about subversion's superiority in the enterprise, are dependent on the perceived insecurity of git and the enterprise-readiness of svn for the long-term success of their products.

But here's the problem: Subversion is an architectural dead-end.

Whereas you can take git and build a centralized subversion replacement quite easily, despite being around for more than twice as long svn has never been able to get even basic merge-tracking working anywhere near as well as it does in git. One basic reason for this is the design decision to make branches the same as directories. I don't know why they went this way originally, it certainly makes partial checkouts very simple. Unfortunately it also makes it impossible to track history properly. Now obviously you are supposed to use subversion repository layout conventions to separate branches from regular directories, and svn uses some heuristics to make things work for the daily use cases. But all this is just papering over a very poor and limiting low-level design decision. Being able to a do a repository-wise diff (rather than directory-wise diff) is basic and critical functionality for a version control system, and greatly simplifies the internals, making it possible to build smarter and useful features on top of it. You can see in the amount of effort that has been put into extending subversion, and yet how far behind it is from the current crop of modern VCSes in terms of fundamental operations like merge resolution.

Now here's my heart-felt and agnostic advice for anyone who still believes Subversion is good enough for the foreseeable future:

Subversion will never catch up to the newer breeds of VCSes that have learned from the mistakes of RCS and CVS; it is a technical impossibility unless they retool the repository model from the ground up, but then it wouldn't really be svn would it? Regardless of how much you think you don't the capabilities of a modern VCS, your ignorance will not protect you from the Subversion's pitfalls, many of which are situations that are impossible or easily resolved in other systems.

It is extremely rare that the technical inferiority of a solution is so clear-cut as it is with svn, certainly I would never state such an opinion about win-vs-linux or emacs-vs-vi, but in this case it is so clearcut, and source control is such a fundamental tool in the developer's arsenal, that I feel it must be stated unequivocally. Regardless of the requirement to use svn for organizational reasons, I implore all svn users not to let their logical mind construct a false belief that more modern VCSes are only useful for large open-source projects. Regardless of the nature of your development work, if you are a programmer, you will be a more effective programmer if you learn how to use better-designed VCSes, whether it be Git, Mercurial, Darcs, or many others.

$val = substr( $url, 0, strrpos( $url, "?"));

Since you said you want to know if its actually installed, I think the best way (short of running version specific code), is to check the reassuringly named "Install" registry key. 0x1 means yes:

C:\>reg query "HKLM\SOFTWARE\Microsoft\NET Framework Setup\NDP\v3.5"| findstr Install

   Install     REG_DWORD       0x1
   InstallPath REG_SZ  c:\WINNT\Microsoft.NET\Framework\v3.5\

This also happens to be the "Microsoft Recommended" official method.

WMI is another possibility, but seems impractical (Slow? Takes 2 min on my C2D, SSD). Maybe it works better on your server:

C:\>wmic product where "Name like 'Microsoft .Net%'" get Name, Version

Name                                                Version
Microsoft .NET Compact Framework 1.0 SP3 Developer  1.0.4292
Microsoft .NET Framework 3.0 Service Pack 2         3.2.30729
Microsoft .NET Framework 3.5 SP1                    3.5.30729
Microsoft .NET Compact Framework 2.0                2.0.5238
Microsoft .NET Framework 4 Client Profile           4.0.30319
Microsoft .NET Framework 4 Multi-Targeting Pack     4.0.30319
Microsoft .NET Framework 2.0 Service Pack 2         2.2.30729
Microsoft .NET Framework 1.1                        1.1.4322
Microsoft .NET Framework 4 Extended                 4.0.30319

C:\>wmic product where "name like 'Microsoft .N%' and version='3.5.30729'" get name

Name  
Microsoft .NET Framework 3.5 SP1

Other than these I think the only way to be 100% sure is to actually run a simple console app compiled targeting your framework version. Personally, I consider this unnecessary and trust the registry method just fine.

Finally, you could set up an intranet test site which is reachable from your server and sniffs the User Agent to determine .NET versions. But that's not a batch file solution of course. Also see doc here.

As stated in other answers, this error may refer to using the wrong python version. In my case, my environment is Windows 10 + Cygwin. In my Windows environment variables, the PATH points to C:\Python38 which is correct, but when I run my command like this:

./my_script.py

I got the ImportError: No module named numpy because the version used in this case is Cygwin's own Python version even if PATH environment variable is correct. All I needed was to run the script like this:

py my_script.py

And this way the problem was solved.

With approach explained by EdChum above, the values in the list are shown as rows. To show the values of lists as columns in DataFrame instead, simply use transpose() as following:

table = [[1 , 2], [3, 4]]
df = pd.DataFrame(table)
df = df.transpose()
df.columns = ['Heading1', 'Heading2']

The output then is:

      Heading1  Heading2
0         1        3
1         2        4

The response provided by Trevor is correct.

But here is what you can directly add in your .gitconfig:

# Enforce SSH

[url "ssh://[email protected]/"]
  insteadOf = https://gitlab.com/

  insteadOf = https://bitbucket.org/

Write a Boolean function that checks the regex and use apply on the column

foo[foo['b'].apply(regex_function)]

val.Replace("-", "");

The main difference between the web containers and application server is that most web containers such as Apache Tomcat implements only basic JSR like Servlet, JSP, JSTL wheres Application servers implements the entire Java EE Specification. Every application server contains web container.

All the answers assume that the functions can be accessed through global scope (window). However, the OP did not make this assumption.

If the functions live in a local scope (aka closure) and are not referenced by some other local object, bad luck: You have to use eval() AFAIK, see dynamically call local function in javascript

Can a Foreign key be NULL?

Existing answers focused on single column scenario. If we consider multi column foreign key we have more options using MATCH [SIMPLE | PARTIAL | FULL] clause defined in SQL Standard:

PostgreSQL-CREATE TABLE

A value inserted into the referencing column(s) is matched against the values of the referenced table and referenced columns using the given match type. There are three match types: MATCH FULL, MATCH PARTIAL, and MATCH SIMPLE (which is the default). MATCH FULL will not allow one column of a multicolumn foreign key to be null unless all foreign key columns are null; if they are all null, the row is not required to have a match in the referenced table. MATCH SIMPLE allows any of the foreign key columns to be null; if any of them are null, the row is not required to have a match in the referenced table. MATCH PARTIAL is not yet implemented.

(Of course, NOT NULL constraints can be applied to the referencing column(s) to prevent these cases from arising.)

Example:

CREATE TABLE A(a VARCHAR(10), b VARCHAR(10), d DATE , UNIQUE(a,b));
INSERT INTO A(a, b, d) 
VALUES (NULL, NULL, NOW()),('a', NULL, NOW()),(NULL, 'b', NOW()),('c', 'b', NOW());

CREATE TABLE B(id INT PRIMARY KEY, ref_a VARCHAR(10), ref_b VARCHAR(10));

-- MATCH SIMPLE - default behaviour nulls are allowed
ALTER TABLE B ADD CONSTRAINT B_Fk FOREIGN KEY (ref_a, ref_b) 
REFERENCES A(a,b) MATCH SIMPLE;

INSERT INTO B(id, ref_a, ref_b) VALUES (1, NULL, 'b');  

-- (NULL/'x') 'x' value does not exists in A table, but insert is valid
INSERT INTO B(id, ref_a, ref_b) VALUES (2, NULL, 'x');  

ALTER TABLE B DROP CONSTRAINT IF EXISTS B_Fk; -- cleanup

-- MATCH PARTIAL - not implemented
ALTER TABLE B ADD CONSTRAINT B_Fk FOREIGN KEY (ref_a, ref_b) 
REFERENCES A(a,b) MATCH PARTIAL;
-- ERROR:  MATCH PARTIAL not yet implemented

DELETE FROM B; ALTER TABLE B DROP CONSTRAINT IF EXISTS B_Fk; -- cleanup

-- MATCH FULL nulls are not allowed
ALTER TABLE B ADD CONSTRAINT B_Fk FOREIGN KEY (ref_a, ref_b) 
REFERENCES A(a,b) MATCH FULL;

-- FK is defined, inserting NULL as part of FK
INSERT INTO B(id, ref_a, ref_b) VALUES (1, NULL, 'b');
-- ERROR:  MATCH FULL does not allow mixing of null and nonnull key values.

-- FK is defined, inserting all NULLs - valid
INSERT INTO B(id, ref_a, ref_b) VALUES (1, NULL, NULL);

db<>fiddle demo

For Mac:

1. Install Pytesseract (pip install pytesseract should work)
2. Install Tesseract but only with homebrew, pip installation somehow doesn't work. (brew install tesseract)
3. Get the path of brew installation of Tesseract on your device (brew list tesseract)
4. Add the path into your code, not in sys path. The path is to be added along with code, using pytesseract.pytesseract.tesseract_cmd = '<path received in step 3>' - (e.g. pytesseract.pytesseract.tesseract_cmd = '/usr/local/Cellar/tesseract/4.0.0_1/bin/tesseract')

This should work fine.

You can parse a string into an integer with int.parse(). For example:

var myInt = int.parse('12345');
assert(myInt is int);
print(myInt); // 12345

Note that int.parse() accepts 0x prefixed strings. Otherwise the input is treated as base-10.

You can parse a string into a double with double.parse(). For example:

var myDouble = double.parse('123.45');
assert(myDouble is double);
print(myDouble); // 123.45

parse() will throw FormatException if it cannot parse the input.

Revised Answer

If you're not calling this code from another program, an option is to skip PL/SQL and do it strictly in SQL using bind variables:

var myname varchar2(20);

exec :myname := 'Tom';

SELECT *
FROM   Customers
WHERE  Name = :myname;

In many tools (such as Toad and SQL Developer), omitting the var and exec statements will cause the program to prompt you for the value.

Original Answer

A big difference between T-SQL and PL/SQL is that Oracle doesn't let you implicitly return the result of a query. The result always has to be explicitly returned in some fashion. The simplest way is to use DBMS_OUTPUT (roughly equivalent to print) to output the variable:

DECLARE
   myname varchar2(20);
BEGIN
     myname := 'Tom';

     dbms_output.print_line(myname);
END;

This isn't terribly helpful if you're trying to return a result set, however. In that case, you'll either want to return a collection or a refcursor. However, using either of those solutions would require wrapping your code in a function or procedure and running the function/procedure from something that's capable of consuming the results. A function that worked in this way might look something like this:

CREATE FUNCTION my_function (myname in varchar2)
     my_refcursor out sys_refcursor
BEGIN
     open my_refcursor for
     SELECT *
     FROM   Customers
     WHERE  Name = myname;

     return my_refcursor;
END my_function;

uint8, uint16, uint32, and uint64 are probably Microsoft-specific types.

As of the 1999 standard, C supports standard typedefs with similar meanings, defined in <stdint.h>: uint8_t, uint16_t, uint32_t, and uint64_t. I'll assume that the Microsoft-specific types are defined similarly. Microsoft does support <stdint.h>, at least as of Visual Studio 2010, but older code may use uint8 et al.

The predefined types char, short, int et al have sizes that vary from one C implementation to another. The C standard has certain minimum requirements (char is at least 8 bits, short and int are at least 16, long is at least 32, and each type in that list is at least as wide as the previous type), but permits some flexibility. For example, I've seen systems where int is 16, 32, or 64 bits.

char is almost always exactly 8 bits, but it's permitted to be wider. And plain char may be either signed or unsigned.

uint8_t is required to be an unsigned integer type that's exactly 8 bits wide. It's likely to be a typedef for unsigned char, though it might be a typedef for plain char if plain char happens to be unsigned. If there is no predefined 8-bit unsigned type, then uint8_t will not be defined at all.

Similarly, each uintN_t type is an unsigned type that's exactly N bits wide.

In addition, <stdint.h> defines corresponding signed intN_t types, as well as int_fastN_t and int_leastN_t types that are at least the specified width.

The [u]intN_t types are guaranteed to have no padding bits, so the size of each is exactly N bits. The signed intN_t types are required to use a 2's-complement representation.

Although uint32_t might be the same as unsigned int, for example, you shouldn't assume that. Use unsigned int when you need an unsigned integer type that's at least 16 bits wide, and that's the "natural" size for the current system. Use uint32_t when you need an unsigned integer type that's exactly 32 bits wide.

(And no, uint64 or uint64_t is not the same as double; double is a floating-point type.)

A neat alternative that is much more readable in my opinion, however, arguably a tad less efficient due to the conversions between double and String:

double num = 540.512;
double sum = 1978.8;

// NOTE: This does take care of rounding
String str = String.format("%.1f", (num/sum) * 100.0); 

If you want the answer as a double, you could of course convert it back:

double ans = Double.parseDouble(str);

Turns out that the post (or rather the whole table) was locked by the very same connection that I tried to update the post with.

I had a opened record set of the post that was created by:

Set RecSet = Conn.Execute()

This type of recordset is supposed to be read-only and when I was using MS Access as database it did not lock anything. But apparently this type of record set did lock something on MS SQL Server 2012 because when I added these lines of code before executing the UPDATE SQL statement...

RecSet.Close
Set RecSet = Nothing

...everything worked just fine.

So bottom line is to be careful with opened record sets - even if they are read-only they could lock your table from updates.

As already stated in earlier answers, ng-pristine is for indicating that the field has not been modified, whereas ng-dirty is for telling it has been modified. Why need both?

Let's say we've got a form with phone and e-mail address among the fields. Either phone or e-mail is required, and you also have to notify the user when they've got invalid data in each field. This can be accomplished by using ng-dirty and ng-pristine together:

<form name="myForm">
    <input name="email" ng-model="data.email" ng-required="!data.phone">
    <div class="error" 
         ng-show="myForm.email.$invalid && 
                  myForm.email.$pristine &&
                  myForm.phone.$pristine">Phone or e-mail required</div>
    <div class="error" 
         ng-show="myForm.email.$invalid && myForm.email.$dirty">
        E-mail is invalid
    </div>

    <input name="phone" ng-model="data.phone" ng-required="!data.email">
    <div class="error" 
         ng-show="myForm.phone.$invalid && 
                  myForm.email.$pristine &&
                  myForm.phone.$pristine">Phone or e-mail required</div>
    <div class="error" 
         ng-show="myForm.phone.$invalid && myForm.phone.$dirty">
        Phone is invalid
    </div>
</form>

You can also do this in a .htaccess file assuming they are enabled on the website.

For a project this size, you should stop writing pure JavaScript and turn to some of the libraries available. I'd recommend jQuery (http://jquery.com/), which allows you to select elements by css-selectors, which I recon should speed up your development quite a bit.

Example of your code then becomes;

function AddtoCart() {
  var len = $("#Items tr").length, $row, $inp1, $inp2, $cells;

  $row = $("#Items td:first").clone(true);
  $cells = $row.find("td");

  $cells.get(0).html( len );

  $inp1 = $cells.get(1).find("input:first");
  $inp1.attr("id", $inp1.attr("id") + len).val("");

  $inp2 = $cells.get(2).find("input:first");
  $inp2.attr("id", $inp2.attr("id") + len).val("");

  $("#Items").append($row);
    }

I can see that you might not understand that code yet, but take a look at jQuery, it's easy to learn and will make this development way faster.

I would use the libraries already created specifically for js shopping carts if I were you though.

To your problem; If i look at your jsFiddle, it doesn't even seem like you have defined a table with the id Items? Maybe that's why it doesn't work?

Make the user submit a post form on that url and the cached redirect is gone :)

<body onload="document.forms[0].submit()">
<form action="https://forum.pirati.cz/unreadposts.html" method="post">

</form>
</body>

works

scp localhost:"f/a\ b\ c" .

scp localhost:'f/a\ b\ c' .

does not work

scp localhost:'f/a b c' .

The reason is that the string is interpreted by the shell before the path is passed to the scp command. So when it gets to the remote the remote is looking for a string with unescaped quotes and it fails

To see this in action, start a shell with the -vx options ie bash -vx and it will display the interpolated version of the command as it runs it.

If you post JSON with content type application/json, use request.get_json() to get it in Flask. If the content type is not correct, None is returned. If the data is not JSON, an error is raised.

    data = request.get_json()

@Greg is correct that one must write explicit comparison functions in the general case.

It is possible to use memcmp if:

• the structs contain no floating-point fields that are possibly NaN.
• the structs contain no padding (use -Wpadded with clang to check this) OR the structs are explicitly initialized with memset at initialization.
• there are no member types (such as Windows BOOL) that have distinct but equivalent values.

Unless you are programming for embedded systems (or writing a library that might be used on them), I would not worry about some of the corner cases in the C standard. The near vs. far pointer distinction does not exist on any 32- or 64- bit device. No non-embedded system that I know of has multiple NULL pointers.

Another option is to auto-generate the equality functions. If you lay your struct definitions out in a simple way, it is possible to use simple text processing to handle simple struct definitions. You can use libclang for the general case – since it uses the same frontend as Clang, it handles all corner cases correctly (barring bugs).

I have not seen such a code generation library. However, it appears relatively simple.

However, it is also the case that such generated equality functions would often do the wrong thing at application level. For example, should two UNICODE_STRING structs in Windows be compared shallowly or deeply?

public class Splash extends Activity {

    Location location;
    LocationManager locationManager;
    LocationListener locationlistener;
    ImageView image_view;
    ublic static ProgressDialog progressdialog;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        setContentView(R.layout.splash);
        progressdialog = new ProgressDialog(Splash.this);
           image_view.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub

                        locationManager.requestLocationUpdates("gps", 100000, 1, locationlistener);
                        Toast.makeText(getApplicationContext(), "Getting Location plz wait...", Toast.LENGTH_SHORT).show();

                            progressdialog.setMessage("getting Location");
                            progressdialog.show();
                            Intent intent = new Intent(Splash.this,Show_LatLng.class);
//                          }
        });
    }

Text here:-
use this for getting activity context for progressdialog

 progressdialog = new ProgressDialog(Splash.this);

or progressdialog = new ProgressDialog(this);

use this for getting application context for BroadcastListener not for progressdialog.

progressdialog = new ProgressDialog(getApplicationContext());
progressdialog = new ProgressDialog(getBaseContext());

Just put this in the header of your PHP Page and it ill work without API:

header('Access-Control-Allow-Origin: *'); //allow everybody  

or

header('Access-Control-Allow-Origin: http://codesheet.org'); //allow just one domain 

or

$http_origin = $_SERVER['HTTP_ORIGIN'];  //allow multiple domains

$allowed_domains = array(
  'http://codesheet.org',
  'http://stackoverflow.com'
);

if (in_array($http_origin, $allowed_domains))
{  
    header("Access-Control-Allow-Origin: $http_origin");
}

You can use the folowing to get the full path to your program like this:

Environment.CurrentDirectory

Try this code:

import subprocess
def process_exists(process_name):
    progs = str(subprocess.check_output('tasklist'))
    if process_name in progs:
        return True
    else:
        return False

And to check if the process is running:

if process_exists('example.exe'):
    #do something

like this

css

textarea {

overflow:scroll;
height:100px;
}

![mvc architecture][1]

Model–view–controller (MVC) is a software architectural pattern for implementing user interfaces. It divides a given software application into three interconnected parts, so as to separate internal representations of information from the ways that information is presented to or accepted from the user.

I was trying to find the meaning of GRANT USAGE on *.* TO and found here. I can clarify that GRANT USAGE on *.* TO user IDENTIFIED BY PASSWORD password will be granted when you create the user with the following command (CREATE):

CREATE USER 'user'@'localhost' IDENTIFIED BY 'password'; 

When you grant privilege with GRANT, new privilege s will be added on top of it.

The standard exceptions can be constructed from a std::string:

#include <stdexcept>

char const * configfile = "hardcode.cfg";
std::string const anotherfile = get_file();

throw std::runtime_error(std::string("Failed: ") + configfile);
throw std::runtime_error("Error: " + anotherfile);

Note that the base class std::exception can not be constructed thus; you have to use one of the concrete, derived classes.

In my case , I got this Error in Tensorflow , Reason was i was trying to feed a array with different length or sequences :

example :

import tensorflow as tf

input_x = tf.placeholder(tf.int32,[None,None])



word_embedding = tf.get_variable('embeddin',shape=[len(vocab_),110],dtype=tf.float32,initializer=tf.random_uniform_initializer(-0.01,0.01))

embedding_look=tf.nn.embedding_lookup(word_embedding,input_x)

with tf.Session() as tt:
    tt.run(tf.global_variables_initializer())

    a,b=tt.run([word_embedding,embedding_look],feed_dict={input_x:example_array})
    print(b)

And if my array is :

example_array = [[1,2,3],[1,2]]

Then i will get error :

ValueError: setting an array element with a sequence.

but if i do padding then :

example_array = [[1,2,3],[1,2,0]]

Now it's working.

You could also override ArrayList to insert nulls between your size and the element you want to add.

import java.util.ArrayList;


public class ArrayListAnySize<E> extends ArrayList<E>{
    @Override
    public void add(int index, E element){
        if(index >= 0 && index <= size()){
            super.add(index, element);
            return;
        }
        int insertNulls = index - size();
        for(int i = 0; i < insertNulls; i++){
            super.add(null);
        }
        super.add(element);
    }
}

Then you can add at any point in the ArrayList. For example, this main method:

public static void main(String[] args){
    ArrayListAnySize<String> a = new ArrayListAnySize<>();
    a.add("zero");
    a.add("one");
    a.add("two");
    a.add(5,"five");
    for(int i = 0; i < a.size(); i++){
        System.out.println(i+": "+a.get(i));
    }
}   

yields this result from the console:

0: zero

1: one

2: two

3: null

4: null

5: five

You could calculate the determinant of the matrix which is recursive and then form the adjoined matrix

Here is a short tutorial

I think this only works for square matrices

Another way of computing these involves gram-schmidt orthogonalization and then transposing the matrix, the transpose of an orthogonalized matrix is its inverse!

Use lt pseudo selector:

$("a:lt(n)")

This matches the elements before the nth one (the nth element excluded). Numbering starts from 0.

1. First of all, there is no difference between View.OnClickListener and OnClickListener. If you just use View.OnClickListener directly, then you don't need to write-

   import android.view.View.OnClickListener

2. You set an OnClickListener instance (e.g. myListener named object)as the listener to a view via setOnclickListener(). When a click event is fired, that myListener gets notified and it's onClick(View view) method is called. Thats where we do our own task. Hope this helps you.

int[] a = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10};

you can use searchField filter of angular.filter

JS:

$scope.users = [
 { first_name: 'Sharon', last_name: 'Melendez' },
 { first_name: 'Edmundo', last_name: 'Hepler' },
 { first_name: 'Marsha', last_name: 'Letourneau' }
];

HTML:

<input ng-model="search" placeholder="search by full name"/> 
<th ng-repeat="user in users | searchField: 'first_name': 'last_name' | filter: search">
  {{ user.first_name }} {{ user.last_name }}
</th>
<!-- so now you can search by full name -->

you can create a shallow clone to only get the last few revisions:

 git clone --depth 1 git://url

then either simply delete the .git directory or use git archive to export your tree.

I do not know how to solve this using code, but I do manually adjust the control panel at the right bottom in the plot figure, and adjust the figure size like:

f, ax = plt.subplots(figsize=(16, 12))

at the meantime until you get a matched size colobar. This worked for me.

Alpine docker image doesn't have bash installed by default. You will need to add following commands to get bash:

RUN apk update && apk add bash

If youre using Alpine 3.3+ then you can just do

RUN apk add --no-cache bash

to keep docker image size small. (Thanks to comment from @sprkysnrky)

It's also important to put

table-layout:fixed;

Onto the containing table, so it operates well in IE9 (if your utilize max-width) as well.

You can validate bobince answer by yourself when you run the following javascript or check this JSFiddle

<div id="timeout"></div>
<div id="interval"></div>

var timeout = 0;
var interval = 0;

function doTimeout(){
    $('#timeout').html(timeout);
    timeout++;
    setTimeout(doTimeout, 1);
}

function doInterval(){
    $('#interval').html(interval);
    interval++;
}

$(function(){
    doTimeout();
    doInterval();
    setInterval(doInterval, 1);
});

Looks like you called it 'ant build..xml'. ant automatically choose a file build.xml in the current directory, so it is enough to call 'ant' (if a default-target is defined) or 'ant target' (the target named target will be called).

With the call 'ant -p' you get a list of targets defined in your build.xml.

Edit: In the comment is shown the call 'ant -verbose build.xml'. To be correct, this has to be called as 'ant -verbose'. The file build.xml in the current directory will be used automatically. If it is needed to explicitly specify the buildfile (because it's name isn't build.xml for example), you have to specify the buildfile with the '-f'-option: 'ant -verbose -f build.xml'. I hope this helps.

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

Depending on your requirements, you might use a Generic class like the one below to make access easier:

import java.util.ArrayList;

class TwoDimentionalArrayList<T> extends ArrayList<ArrayList<T>> {
    public void addToInnerArray(int index, T element) {
        while (index >= this.size()) {
            this.add(new ArrayList<T>());
        }
        this.get(index).add(element);
    }

    public void addToInnerArray(int index, int index2, T element) {
        while (index >= this.size()) {
            this.add(new ArrayList<T>());
        }

        ArrayList<T> inner = this.get(index);
        while (index2 >= inner.size()) {
            inner.add(null);
        }

        inner.set(index2, element);
    }
}

If you set the margin to be margin:0 auto the image will be centered.

This will give top + bottom a margin of 0, and left and right a margin of 'auto'. Since the div has a width (200px), the image will be 200px wide and the browser will auto set the left and right margin to half of what is left on the page, which will result in the image being centered.

You can also force the code to be reloaded every hour, like this, in PHP :

<?php
echo '<script language="JavaScript" src="js/myscript.js?token='.date('YmdH').'">';
?>

or

<script type="text/javascript" src="js/myscript.js?v=<?php echo date('YmdHis'); ?>"></script>

Use double braces {{ or }} so your code becomes:

sb.AppendLine(String.Format("public {0} {1} {{ get; private set; }}", 
prop.Type, prop.Name));

// For prop.Type of "Foo" and prop.Name of "Bar", the result would be:
// public Foo Bar { get; private set; }

I install with npm install --save-dev webpack-dev-server then I set package.json and webpack.config.js like this: setting.

Then I run webpack-dev-server and get this error error.

If I don't use npm install -g webpack-dev-server to install, then how to fix it?

I fixed the error configuration has an unknown property 'colors' by removing colors:true. It worked!

For almost all cases the normal list is the right choice. The arrays module is more like a thin wrapper over C arrays, which give you kind of strongly typed containers (see docs), with access to more C-like types such as signed/unsigned short or double, which are not part of the built-in types. I'd say use the arrays module only if you really need it, in all other cases stick with lists.

if you use glide you can do it like this.

Glide.with(yourImageView).clear(yourImageView)

You are passing a reference to the list, but your aren't passing the list variable by reference - so when you call ChangeList the value of the variable (i.e. the reference - think "pointer") is copied - and changes to the value of the parameter inside ChangeList aren't seen by TestMethod.

try:

private void ChangeList(ref List<int> myList) {...}
...
ChangeList(ref myList);

This then passes a reference to the local-variable myRef (as declared in TestMethod); now, if you reassign the parameter inside ChangeList you are also reassigning the variable inside TestMethod.

You don't need to pass this, there already is the event object passed by default automatically, which contains event.target which has the object it's coming from. You can lighten your syntax:

This:

<p onclick="doSomething()">

Will work with this:

function doSomething(){
  console.log(event);
  console.log(event.target);
}

You don't need to instantiate the event object, it's already there. Try it out. And event.target will contain the entire object calling it, which you were referencing as "this" before.

Now if you dynamically trigger doSomething() from somewhere in your code, you will notice that event is undefined. This is because it wasn't triggered from an event of clicking. So if you still want to artificially trigger the event, simply use dispatchEvent:

document.getElementById('element').dispatchEvent(new CustomEvent("click", {'bubbles': true}));

Then doSomething() will see event and event.target as per usual!

No need to pass this everywhere, and you can keep your function signatures free from wiring information and simplify things.

Not sure what you mean with "class constructor" but I'd assume you mean one of the ones below.

Instance constructor:

Public Sub New()

End Sub

Shared constructor:

Shared Sub New()

End Sub

You may want one of these, so to correspond to the Bootstrap layout:

<div class="col-xs-12">
    <hr >
</div>

<!-- or -->

<div class="col-xs-12">
    <hr style="border-style: dashed; border-top-width: 2px;">
</div>

<!-- or -->

<div class="col-xs-12">
    <hr class="col-xs-1" style="border-style: dashed; border-top-width: 2px;">
</div>

Without a DIV grid element included, layout may brake on different devices.

Update: Based on this question's title, people seem to come here just looking for a way to find a different user's home directory, without the need to impersonate that user.

In that case, the simplest solution is to use tilde expansion with the username of interest, combined with eval (which is needed, because the username must be given as an unquoted literal in order for tilde expansion to work):

eval echo "~$different_user"    # prints $different_user's home dir.

Note: The usual caveats regarding the use of eval apply; in this case, the assumption is that you control the value of $different_user and know it to be a mere username.

By contrast, the remainder of this answer deals with impersonating a user and performing operations in that user's home directory.

Note:

• Administrators by default and other users if authorized via the sudoers file can impersonate other users via sudo.
• The following is based on the default configuration of sudo - changing its configuration can make it behave differently - see man sudoers.

The basic form of executing a command as another user is:

sudo -H -u someUser someExe [arg1 ...]
  # Example:
sudo -H -u root env  # print the root user's environment

Note:

• If you neglect to specify -H, the impersonating process (the process invoked in the context of the specified user) will report the original user's home directory in $HOME.
• The impersonating process will have the same working directory as the invoking process.
• The impersonating process performs no shell expansions on string literals passed as arguments, since no shell is involved in the impersonating process (unless someExe happens to be a shell) - expansions by the invoking shell - prior to passing to the impersonating process - can obviously still occur.

Optionally, you can have an impersonating process run as or via a(n impersonating) shell, by prefixing someExe either with -i or -s - not specifying someExe ... creates an interactive shell:

• -i creates a login shell for someUser, which implies the following:

  • someUser's user-specific shell profile, if defined, is loaded.
  • $HOME points to someUser's home directory, so there's no need for -H (though you may still specify it)
  • The working directory for the impersonating shell is the someUser's home directory.

• -s creates a non-login shell:

  • no shell profile is loaded (though initialization files for interactive nonlogin shells are; e.g., ~/.bashrc)
  • Unless you also specify -H, the impersonating process will report the original user's home directory in $HOME.
  • The impersonating shell will have the same working directory as the invoking process.

Using a shell means that string arguments passed on the command line MAY be subject to shell expansions - see platform-specific differences below - by the impersonating shell (possibly after initial expansion by the invoking shell); compare the following two commands (which use single quotes to prevent premature expansion by the invoking shell):

  # Run root's shell profile, change to root's home dir.
sudo -u root -i eval 'echo $SHELL - $USER - $HOME - $PWD'
  # Don't run root's shell profile, use current working dir.
  # Note the required -H to define $HOME as root`s home dir.
sudo -u root -H -s eval 'echo $SHELL - $USER - $HOME - $PWD'

What shell is invoked is determined by "the SHELL environment variable if it is set or the shell as specified in passwd(5)" (according to man sudo). Note that with -s it is the invoking user's environment that matters, whereas with -i it is the impersonated user's.

Note that there are platform differences regarding shell-related behavior (with -i or -s):

• sudo on Linux apparently only accepts an executable or builtin name as the first argument following -s/-i, whereas OSX allows passing an entire shell command line; e.g., OSX accepts sudo -u root -s 'echo $SHELL - $USER - $HOME - $PWD' directly (no need for eval), whereas Linux doesn't (as of sudo 1.8.95p).

• Older versions of sudo on Linux do NOT apply shell expansions to arguments passed to a shell; for instance, with sudo 1.8.3p1 (e.g., Ubuntu 12.04), sudo -u root -H -s echo '$HOME' simply echoes the string literal "$HOME" instead of expanding the variable reference in the context of the root user. As of at least sudo 1.8.9p5 (e.g., Ubuntu 14.04) this has been fixed. Therefore, to ensure expansion on Linux even with older sudo versions, pass the the entire command as a single argument to eval; e.g.: sudo -u root -H -s eval 'echo $HOME'. (Although not necessary on OSX, this will work there, too.)

• The root user's $SHELL variable contains /bin/sh on OSX 10.9, whereas it is /bin/bash on Ubuntu 12.04.

Whether the impersonating process involves a shell or not, its environment will have the following variables set, reflecting the invoking user and command: SUDO_COMMAND, SUDO_USER, SUDO_UID=, SUDO_GID.

See man sudo and man sudoers for many more subtleties.

Tip of the hat to @DavidW and @Andrew for inspiration.

Note: This is only for Mac users

I had same issue but none of the answers posted helped since there was no tools folder present in Library/Android/sdk. (I'm using Android 3.6.3 on Mac OS 10.14.4)

Below steps helped me to overcome licensing problem error:

1. Open Android Studio
2. Press cmd + shift + A. This opens Actions pop-up window.
3. Search for SDK Manager and hit enter to open.
4. This opens pop-up for Android SDK. Select some other version of Android apart from already installed one. (In my case Android 10.0 was already installed so I selected Android 9.0)
5. Then select Apply button. This will install corresponding SDK.

6. Now run your app it should work without any exception.

Using Fetch and async function

const logFileText = async file => {
    const response = await fetch(file)
    const text = await response.text()
    console.log(text)
}

logFileText('file.txt')

As GvS said, but I also find it useful to use strongly typed views so that I can write something like

@Html.Partial(MVC.Student.Index(), model)

without magic strings.

No, using sessions does not necessarily violate RESTfulness. If you adhere to the REST precepts and constraints, then using sessions - to maintain state - will simply be superfluous. After all, RESTfulness requires that the server not maintain state.

For such a simple application even MFC would be overkill. If don't want to introduce another dependency just do it in plain vanilla Win32. It will be easier for you if you have never used MFC.

Check out the classic "Programming Windows" by Charles Petzold or some online tutorial (e.g. http://www.winprog.org/tutorial/) and you are ready to go.

First you need an object

public class MyObject {
  public string Id {get;set;}
  public string Text {get;set;}
  ...
}

Then in here

    using (var twitpicResponse = (HttpWebResponse)request.GetResponse()) {

        using (var reader = new StreamReader(twitpicResponse.GetResponseStream())) {
            JavaScriptSerializer js = new JavaScriptSerializer();
            var objText = reader.ReadToEnd();
            MyObject myojb = (MyObject)js.Deserialize(objText,typeof(MyObject));
        }

    }

I haven't tested with the hierarchical object you have, but this should give you access to the properties you want.

JavaScriptSerializer System.Web.Script.Serialization

After some thinking i came up with this solution:

 LENGTHB(TO_CHAR(SUBSTR(<CLOB-Column>,1,4000)))

SUBSTR returns only the first 4000 characters (max string size)

TO_CHAR converts from CLOB to VARCHAR2

LENGTHB returns the length in Bytes used by the string.

Because of the recursive nature of JSON (nested {...}-s), regex is not suited to validate it. Sure, some regex flavours can recursively match patterns^* (and can therefor match JSON), but the resulting patterns are horrible to look at, and should never ever be used in production code IMO!

^* Beware though, many regex implementations do not support recursive patterns. Of the popular programming languages, these support recursive patterns: Perl, .NET, PHP and Ruby 1.9.2

You need a Flask view that will receive POST data and an HTML form that will send it.

from flask import request

@app.route('/addRegion', methods=['POST'])
def addRegion():
    ...
    return (request.form['projectFilePath'])

<form action="{{ url_for('addRegion') }}" method="post">
    Project file path: <input type="text" name="projectFilePath"><br>
    <input type="submit" value="Submit">
</form>

Do it like this:

$foo = new stdClass();
$foo->{"bar"} = '1234';

now try:

echo $foo->bar; // should display 1234

In this case what you can do is : Go in developer options on the device Uncheck "USB Debugging" then check it again A confirmation box should then appear DvxWifiScan

I solved this error by installing the browser driver:

1. Navigate your browser to seleniumhq.org website
2. Select the Downloads tab
3. Scroll down the page to the Browser section and download the driver you want by clicking the link, for example, Google Chrome Driver
4. Double-click the downloaded file, for example, chromedriver_mac64(1).zip
5. Double-click the extracted file, for example, chromedriver

Reference: search YouTube.com for the error

Platform: macOS High Sierra 10.13.3

using https://github.com/nicfit/eyeD3

import eyed3
import os

for root,  dirs, files in os.walk(folderp):
    for file in files:
        try:
            if file.find(".mp3") < 0:
                continue
            path = os.path.abspath(os.path.join(root , file))
            t = eyed3.load(path)
            print(t.tag.title , t.tag.artist)
            #print(t.getArtist())
        except Exception as e:
            print(e)
            continue

The part you should be interested in is the /? part, which should solve most other questions you have with the tool.

Microsoft Windows XP [Version 5.1.2600]
(C) Copyright 1985-2001 Microsoft Corp.

C:\>cmd /?
Starts a new instance of the Windows XP command interpreter

CMD [/A | /U] [/Q] [/D] [/E:ON | /E:OFF] [/F:ON | /F:OFF] [/V:ON | /V:OFF]
    [[/S] [/C | /K] string]

/C      Carries out the command specified by string and then terminates
/K      Carries out the command specified by string but remains
/S      Modifies the treatment of string after /C or /K (see below)
/Q      Turns echo off
/D      Disable execution of AutoRun commands from registry (see below)
/A      Causes the output of internal commands to a pipe or file to be ANSI
/U      Causes the output of internal commands to a pipe or file to be
        Unicode
/T:fg   Sets the foreground/background colors (see COLOR /? for more info)
/E:ON   Enable command extensions (see below)
/E:OFF  Disable command extensions (see below)
/F:ON   Enable file and directory name completion characters (see below)
/F:OFF  Disable file and directory name completion characters (see below)
/V:ON   Enable delayed environment variable expansion using ! as the
        delimiter. For example, /V:ON would allow !var! to expand the
        variable var at execution time.  The var syntax expands variables
        at input time, which is quite a different thing when inside of a FOR
        loop.
/V:OFF  Disable delayed environment expansion.

You cannot directly change a form's validity. If all the descendant inputs are valid, the form is valid, if not, then it is not.

What you should do is to set the validity of the input element. Like so;

addItem.capabilities.$setValidity("youAreFat", false);

Now the input (and so the form) is invalid. You can also see which error causes invalidation.

addItem.capabilities.errors.youAreFat == true;

String removeCurrency=amount.getText().toString().substring(3);

mysql version 5.5 set datetime default value as CURRENT_TIMESTAMP will be report error you can update to version 5.6 , it set datetime default value as CURRENT_TIMESTAMP

This is an example of using REG_EXTENDED. This regular expression

"^(-)?([0-9]+)((,|.)([0-9]+))?\n$"

Allows you to catch decimal numbers in Spanish system and international. :)

#include <regex.h>
#include <stdlib.h>
#include <stdio.h>
regex_t regex;
int reti;
char msgbuf[100];

int main(int argc, char const *argv[])
{
    while(1){
        fgets( msgbuf, 100, stdin );
        reti = regcomp(&regex, "^(-)?([0-9]+)((,|.)([0-9]+))?\n$", REG_EXTENDED);
        if (reti) {
            fprintf(stderr, "Could not compile regex\n");
            exit(1);
        }

        /* Execute regular expression */
        printf("%s\n", msgbuf);
        reti = regexec(&regex, msgbuf, 0, NULL, 0);
        if (!reti) {
            puts("Match");
        }
        else if (reti == REG_NOMATCH) {
            puts("No match");
        }
        else {
            regerror(reti, &regex, msgbuf, sizeof(msgbuf));
            fprintf(stderr, "Regex match failed: %s\n", msgbuf);
            exit(1);
        }

        /* Free memory allocated to the pattern buffer by regcomp() */
        regfree(&regex);
    }

}

There is much simpler way:

using System;
using System.Collections.Generic;
....
var caseInsensitiveDictionary = new Dictionary<string, string>(StringComparer.OrdinalIgnoreCase);

Try this:

UPDATE business AS b
INNER JOIN business_geocode AS g ON b.business_id = g.business_id
SET b.mapx = g.latitude,
  b.mapy = g.longitude
WHERE  (b.mapx = '' or b.mapx = 0) and
  g.latitude > 0

Update:

Since you said the query yielded a syntax error, I created some tables that I could test it against and confirmed that there is no syntax error in my query:

mysql> create table business (business_id int unsigned primary key auto_increment, mapx varchar(255), mapy varchar(255)) engine=innodb;
Query OK, 0 rows affected (0.01 sec)

mysql> create table business_geocode (business_geocode_id int unsigned primary key auto_increment, business_id int unsigned not null, latitude varchar(255) not null, longitude varchar(255) not null, foreign key (business_id) references business(business_id)) engine=innodb;
Query OK, 0 rows affected (0.01 sec)

mysql> UPDATE business AS b
    -> INNER JOIN business_geocode AS g ON b.business_id = g.business_id
    -> SET b.mapx = g.latitude,
    ->   b.mapy = g.longitude
    -> WHERE  (b.mapx = '' or b.mapx = 0) and
    ->   g.latitude > 0;
Query OK, 0 rows affected (0.00 sec)
Rows matched: 0  Changed: 0  Warnings: 0

See? No syntax error. I tested against MySQL 5.5.8.

@Component({
  selector: 'key-up3',
  template: `
    <input #box (keyup.enter)="doSomething($event)">
    <p>{{values}}</p>
  `
})
export class KeyUpComponent_v3 {
  doSomething(e) {
    alert(e);
  }
}

This works for me!

You're looking for foreign keys. Basically you can't have an array in a database unless it has it's own table.

Example schema:

    Users Table
        userID PK
        other data
    Friends Table
        userID   -- FK to users's table representing the user that has a friend.
        friendID -- FK to Users' table representing the user id of the friend

If you prefer to use a library, use ts-essentials.

import { Omit } from "ts-essentials";

type ComplexObject = {
  simple: number;
  nested: {
    a: string;
    array: [{ bar: number }];
  };
};

type SimplifiedComplexObject = Omit<ComplexObject, "nested">;

// Result:
// {
//  simple: number
// }

// if you want to Omit multiple properties just use union type:
type SimplifiedComplexObject = Omit<ComplexObject, "nested" | "simple">;

// Result:
// { } (empty type)

PS: You will find lots of other useful stuff there ;)

The usual solution to this problem is setuiding a helper app that performs the task requiring superuser access: http://en.wikipedia.org/wiki/Setuid

Sudo is not meant to be used offline.

Later edit: SSH can be used with private-public key authentication. If the private key does not have a passphrase, ssh can be used without prompting for a password.

You can get div content using .text() in jquery

var divContent = $('#field-function_purpose').text();
console.log(divContent);

Fiddle

Single exit point - all other things equal - makes code significantly more readable. But there's a catch: popular construction

resulttype res;
if if if...
return res;

is a fake, "res=" is not much better than "return". It has single return statement, but multiple points where function actually ends.

If you have function with multiple returns (or "res="s), it's often a good idea to break it into several smaller functions with single exit point.

You also can Redirect within the Route as follows. This is for handle invalid routes.

<Route path='*' render={() => 
     (
       <Redirect to="/error"/>
     )
}/>

from datetime import datetime

datetime.strptime(date_string, "%Y-%m-%d")

..this raises a ValueError if it receives an incompatible format.

..if you're dealing with dates and times a lot (in the sense of datetime objects, as opposed to unix timestamp floats), it's a good idea to look into the pytz module, and for storage/db, store everything in UTC.

Life cycle management is one of the responsibilities dependency containers assume in addition to instantiation and injection. The fact that the container sometimes keep a reference to the components after instantiation is the reason it is called a "container", and not a factory. Dependency injection containers usually only keep a reference to objects it needs to manage life cycles for, or that are reused for future injections, like singletons or flyweights. When configured to create new instances of some components for each call to the container, the container usually just forgets about the created object.

You should put it in the <head>. I typically put style references above JS and I order my JS from top to bottom if some of them are dependent on others, but I beleive all of the references are loaded before the page is rendered.

unfortunately, with "mvim -v", ALT plus arrow windows still does not work. I have not found any way to enable it :-(

If you are using Ubuntu try to install following lib file

sudo apt-get install libpq-dev

and then

gem install pg

worked for me.

I was looking through source 1.3.2, when using JSONP, the request is made by building a SCRIPT element dynamically, which gets past the browsers Same-domain policy. Naturally, you can't make a POST request using a SCRIPT element, the browser would fetch the result using GET.

As you are requesting a JSONP call, the SCRIPT element is not generated, because it only does this when the Type of AJAX call is set to GET.

Disclaimer

Parsing a string back to date/time value in an unknown format is inherently impossible (let's face it, what does 3/3/3 actually mean?!), all we can do is "best effort"

Important

This solution doesn't throw an Exception, it returns a boolean, this is by design. Any Exceptions are used purely as a guard mechanism.

2018

Since it's now 2018 and Java 8+ has the date/time API (and the rest have the ThreeTen backport). The solution remains basically the same, but becomes slightly more complicated, as we need to perform checks for:

• date and time
• date only
• time only

This makes it look something like...

public static boolean isValidFormat(String format, String value, Locale locale) {
    LocalDateTime ldt = null;
    DateTimeFormatter fomatter = DateTimeFormatter.ofPattern(format, locale);

    try {
        ldt = LocalDateTime.parse(value, fomatter);
        String result = ldt.format(fomatter);
        return result.equals(value);
    } catch (DateTimeParseException e) {
        try {
            LocalDate ld = LocalDate.parse(value, fomatter);
            String result = ld.format(fomatter);
            return result.equals(value);
        } catch (DateTimeParseException exp) {
            try {
                LocalTime lt = LocalTime.parse(value, fomatter);
                String result = lt.format(fomatter);
                return result.equals(value);
            } catch (DateTimeParseException e2) {
                // Debugging purposes
                //e2.printStackTrace();
            }
        }
    }

    return false;
}

This makes the following...

System.out.println("isValid - dd/MM/yyyy with 20130925 = " + isValidFormat("dd/MM/yyyy", "20130925", Locale.ENGLISH));
System.out.println("isValid - dd/MM/yyyy with 25/09/2013 = " + isValidFormat("dd/MM/yyyy", "25/09/2013", Locale.ENGLISH));
System.out.println("isValid - dd/MM/yyyy with 25/09/2013 12:13:50 = " + isValidFormat("dd/MM/yyyy", "25/09/2013  12:13:50", Locale.ENGLISH));
System.out.println("isValid - yyyy-MM-dd with 2017-18--15 = " + isValidFormat("yyyy-MM-dd", "2017-18--15", Locale.ENGLISH));

output...

isValid - dd/MM/yyyy with 20130925 = false
isValid - dd/MM/yyyy with 25/09/2013 = true
isValid - dd/MM/yyyy with 25/09/2013 12:13:50 = false
isValid - yyyy-MM-dd with 2017-18--15 = false

Original Answer

Simple try and parse the String to the required Date using something like SimpleDateFormat

Date date = null;
try {
    SimpleDateFormat sdf = new SimpleDateFormat(format);
    date = sdf.parse(value);
    if (!value.equals(sdf.format(date))) {
        date = null;
    }
} catch (ParseException ex) {
    ex.printStackTrace();
}
if (date == null) {
    // Invalid date format
} else {
    // Valid date format
}

You could then simply write a simple method that performed this action and returned true when ever Date was not null...

As a suggestion...

Updated with running example

I'm not sure what you are doing, but, the following example...

import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Date;

public class TestDateParser {

    public static void main(String[] args) {
        System.out.println("isValid - dd/MM/yyyy with 20130925 = " + isValidFormat("dd/MM/yyyy", "20130925"));
        System.out.println("isValid - dd/MM/yyyy with 25/09/2013 = " + isValidFormat("dd/MM/yyyy", "25/09/2013"));
        System.out.println("isValid - dd/MM/yyyy with 25/09/2013 12:13:50 = " + isValidFormat("dd/MM/yyyy", "25/09/2013  12:13:50"));
    }

    public static boolean isValidFormat(String format, String value) {
        Date date = null;
        try {
            SimpleDateFormat sdf = new SimpleDateFormat(format);
            date = sdf.parse(value);
            if (!value.equals(sdf.format(date))) {
                date = null;
            }
        } catch (ParseException ex) {
            ex.printStackTrace();
        }
        return date != null;
    }

}

Outputs (something like)...

java.text.ParseException: Unparseable date: "20130925"
isValid - dd/MM/yyyy with 20130925 = false
isValid - dd/MM/yyyy with 25/09/2013 = true
isValid - dd/MM/yyyy with 25/09/2013 12:13:50 = false
    at java.text.DateFormat.parse(DateFormat.java:366)
    at javaapplication373.JavaApplication373.isValidFormat(JavaApplication373.java:28)
    at javaapplication373.JavaApplication373.main(JavaApplication373.java:19)

Not correct. For isValidFormat("yyyy-MM-dd", "2017-18--15"); not throw any Exception.

isValid - yyyy-MM-dd", "2017-18--15 = false

Seems to work as expected for me - the method doesn't rely on (nor does it throw) the exception alone to perform it's operation

If you want more control over how the conversion takes place, you can use ConvertAll:

var stringList = myList.ConvertAll(obj => obj.SomeToStringMethod());

Regardless of whether I define this in the main CMakeLists.txt or in the individual ones, it still assumes I want all the libs and bins off the main path, which is the least useful assumption of all.

If the above answers still do not work, add this:

button:focus{
    outline: none!important;
    box-shadow:none;
}

The header just denotes what the content is encoded in. It is not necessarily possible to deduce the type of the content from the content itself, i.e. you can't necessarily just look at the content and know what to do with it. That's what HTTP headers are for, they tell the recipient what kind of content they're (supposedly) dealing with.

Content-type: application/json; charset=utf-8 designates the content to be in JSON format, encoded in the UTF-8 character encoding. Designating the encoding is somewhat redundant for JSON, since the default (only?) encoding for JSON is UTF-8. So in this case the receiving server apparently is happy knowing that it's dealing with JSON and assumes that the encoding is UTF-8 by default, that's why it works with or without the header.

Does this encoding limit the characters that can be in the message body?

No. You can send anything you want in the header and the body. But, if the two don't match, you may get wrong results. If you specify in the header that the content is UTF-8 encoded but you're actually sending Latin1 encoded content, the receiver may produce garbage data, trying to interpret Latin1 encoded data as UTF-8. If of course you specify that you're sending Latin1 encoded data and you're actually doing so, then yes, you're limited to the 256 characters you can encode in Latin1.

I used the following setup to direct everything on /rest to my backend server (on port 8080), and all other requests to the frontend server (a webpack server on port 3001). It supports all HTTP-methods, doesn't lose any request meta-info and supports websockets (which I need for hot reloading)

var express  = require('express');
var app      = express();
var httpProxy = require('http-proxy');
var apiProxy = httpProxy.createProxyServer();
var backend = 'http://localhost:8080',
    frontend = 'http://localhost:3001';

app.all("/rest/*", function(req, res) {
  apiProxy.web(req, res, {target: backend});
});

app.all("/*", function(req, res) {
    apiProxy.web(req, res, {target: frontend});
});

var server = require('http').createServer(app);
server.on('upgrade', function (req, socket, head) {
  apiProxy.ws(req, socket, head, {target: frontend});
});
server.listen(3000);

Use x=as.name("string"). You can use then use x to refer to the variable with name string.

I don't know, if it answers your question correctly.

On Windows you can use module 'win32console' (available in some Python distributions) or module 'ctypes' (Python 2.5 and up) to access the Win32 API.

To see complete code that supports both ways, see the color console reporting code from Testoob.

ctypes example:

import ctypes

# Constants from the Windows API
STD_OUTPUT_HANDLE = -11
FOREGROUND_RED    = 0x0004 # text color contains red.

def get_csbi_attributes(handle):
    # Based on IPython's winconsole.py, written by Alexander Belchenko
    import struct
    csbi = ctypes.create_string_buffer(22)
    res = ctypes.windll.kernel32.GetConsoleScreenBufferInfo(handle, csbi)
    assert res

    (bufx, bufy, curx, cury, wattr,
    left, top, right, bottom, maxx, maxy) = struct.unpack("hhhhHhhhhhh", csbi.raw)
    return wattr


handle = ctypes.windll.kernel32.GetStdHandle(STD_OUTPUT_HANDLE)
reset = get_csbi_attributes(handle)

ctypes.windll.kernel32.SetConsoleTextAttribute(handle, FOREGROUND_RED)
print "Cherry on top"
ctypes.windll.kernel32.SetConsoleTextAttribute(handle, reset)

Rename the module to something other than 'file'.

Then also be sure when you are calling the function that:

1)if you are importing the entire module, you reiterate the module name when calling it:

import module
module.function_name()

or

import pizza
pizza.pizza_function()

2)or if you are importing specific functions, functions with an alias, or all functions using *, you don't reiterate the module name:

from pizza import pizza_function
pizza_function()

or

from pizza import pizza_function as pf
pf()

or

from pizza import *
pizza_function()

Just start it with a slash? This means root. As long as you're testing on a web server (e.g. localhost) and not a file system (e.g. C:) then that should be all you need to do.
