Just change the directory to another one and come back. Probably that one has been deleted or moved.

In Ubuntu 16.04.3 LTS, the next command works for me:

exit

Then I've login again.

Here's what I ended up with. This works for me if I import my script in the interpreter, and also if I execute it as a script:

import os
import sys

# Returns the directory the current script (or interpreter) is running in
def get_script_directory():
    path = os.path.realpath(sys.argv[0])
    if os.path.isdir(path):
        return path
    else:
        return os.path.dirname(path)

Actually you don't have to create an image at all. drawImage() will accept a Canvas as well as an Image object.

//grab the context from your destination canvas
var destCtx = destinationCanvas.getContext('2d');

//call its drawImage() function passing it the source canvas directly
destCtx.drawImage(sourceCanvas, 0, 0);

Way faster than using an ImageData object or Image element.

Note that sourceCanvas can be a HTMLImageElement, HTMLVideoElement, or a HTMLCanvasElement. As mentioned by Dave in a comment below this answer, you cannot use a canvas drawing context as your source. If you have a canvas drawing context instead of the canvas element it was created from, there is a reference to the original canvas element on the context under context.canvas.

Here is a jsPerf to demonstrate why this is the only right way to clone a canvas: http://jsperf.com/copying-a-canvas-element

You're looking to create a custom A record.

I'm pretty sure that you can use wildcards when specifying A records which would let you do something like this:

*.mywebsite.com       IN  A       127.0.0.1

127.0.0.1 would be the IP address of your webserver. The method of actually adding the record will depend on your host.

Doing it like http://mywebsite.com/user would be a lot easier to set up if it's an option.

Then you could just add a .htaccess file that looks like this:

Options +FollowSymLinks

RewriteEngine On
RewriteRule ^([aA-zZ])$  dostuff.php?username=$1

In the above, usernames are limited to the characters a-z

The rewrite rule for grabbing the subdomain would look like this:

RewriteCond %{HTTP_HOST} ^(^.*)\.mywebsite.com
RewriteRule (.*)  dostuff.php?username=%1

However, you don't really need any rewrite rules. The HTTP_HOST header is available in PHP as well, so you can get it already, like

$username = strtok($_SERVER['HTTP_HOST'], ".");

Once you have a json object

obj.valueOf(Object.keys(obj).indexOf('String_to_Find'))

This works better in my case if you have object or multi-dimensional array. It will shows only first items, other will be just ignored in loop.

.filter('limitItems', function () {
  return function (items) {
    var result = {}, i = 1;
    angular.forEach(items, function(value, key) {
      if (i < 5) {
        result[key] = value;
      }
      i = i + 1;
    });
    return result;
  };
});

Change 5 on what you want.

1. Open Connetion
2. Select "Administration" tab
3. Click on Data import

Upload sql file

Make sure to select your database in this award winning GUI:

This C# code is to fetch all items from a dynamodb table using BatchGet or CreateBatchGet

        string tablename = "AnyTableName"; //table whose data you want to fetch

        var BatchRead = ABCContext.Context.CreateBatchGet<ABCTable>(  

            new DynamoDBOperationConfig
            {
                OverrideTableName = tablename; 
            });

        foreach(string Id in IdList) // in case you are taking string from input
        {
            Guid objGuid = Guid.Parse(Id); //parsing string to guid
            BatchRead.AddKey(objGuid);
        }

        await BatchRead.ExecuteAsync();
        var result = BatchRead.Results;

// ABCTable is the table modal which is used to create in dynamodb & data you want to fetch

You code should be:

   <section id="right">
      <label for="form_msg">Message</label>
      <textarea name="form_msg" id="#msg_text"></textarea>
      <input id="submit" class="button" name="submit" type="submit" value="Send">
   </section>

Js

var data = {
    name: $("#form_name").val(),
    email: $("#form_email").val(),
    message: $("#msg_text").val()
};
$.ajax({
    type: "POST",
    url: "email.php",
    data: data,
    success: function(){
        $('.success').fadeIn(1000);
    }
});

The PHP:

<?php
if($_POST){
    $name = $_POST['name'];
    $email = $_POST['email'];
    $message = $_POST['text'];

//send email
    mail("[email protected]","My Subject:",$email,$message);
}
?>

According to the documentation.

If you are running on the TensorFlow or CNTK backends, your code will automatically run on GPU if any available GPU is detected.

You can check what all devices are used by tensorflow by -

from tensorflow.python.client import device_lib
print(device_lib.list_local_devices())

Also as suggested in this answer

import tensorflow as tf
sess = tf.Session(config=tf.ConfigProto(log_device_placement=True))

This will print whether your tensorflow is using a CPU or a GPU backend. If you are running this command in jupyter notebook, check out the console from where you have launched the notebook.

If you are sceptic whether you have installed the tensorflow gpu version or not. You can install the gpu version via pip.

pip install tensorflow-gpu

const absolutePath = path.join(__dirname, some, dir);

vs.

const absolutePath = path.resolve(__dirname, some, dir);

path.join will concatenate __dirname which is the directory name of the current file concatenated with values of some and dir with platform-specific separator.

Whereas

path.resolve will process __dirname, some and dir i.e. from right to left prepending it by processing it.

If any of the values of some or dir corresponds to a root path then the previous path will be omitted and process rest by considering it as root

In order to better understand the concept let me explain both a little bit more detail as follows:-

The path.join and path.resolve are two different methods or functions of the path module provided by nodejs.

Where both accept a list of paths but the difference comes in the result i.e. how they process these paths.

path.join concatenates all given path segments together using the platform-specific separator as a delimiter, then normalizes the resulting path. While the path.resolve() process the sequence of paths from right to left, with each subsequent path prepended until an absolute path is constructed.

When no arguments supplied

The following example will help you to clearly understand both concepts:-

My filename is index.js and the current working directory is E:\MyFolder\Pjtz\node

const path = require('path');

console.log("path.join() : ", path.join());
// outputs .
console.log("path.resolve() : ", path.resolve());
// outputs current directory or equivalent to __dirname

Result

? node index.js
path.join() :  .
path.resolve() :  E:\MyFolder\Pjtz\node

path.resolve() method will output the absolute path whereas the path.join() returns . representing the current working directory if nothing is provided

When some root path is passed as arguments

const path=require('path');

console.log("path.join() : " ,path.join('abc','/bcd'));
console.log("path.resolve() : ",path.resolve('abc','/bcd'));

Result i

? node index.js
path.join() :  abc\bcd
path.resolve() :  E:\bcd

path.join() only concatenates the input list with platform-specific separator while the path.resolve() process the sequence of paths from right to left, with each subsequent path prepended until an absolute path is constructed.

One approach would be to take a defaults object and merge it with the target object. The target object would override values in the defaults object.

jQuery has the .extend() method that does this. jQuery is not needed however as there are vanilla JS implementations such as can be found here:

http://gomakethings.com/vanilla-javascript-version-of-jquery-extend/

From the AWK man page:

system(cmd)
              executes cmd and returns its exit status

The GNU AWK manual also has a section that, in part, describes the system function and provides an example:

system("date | mail -s 'awk run done' root")

Apply the following in your Theme for the Activity in AndroidManifest.xml:

<activity android:name=".DashboardActivity"
        android:theme="@style/AppFullScreenTheme">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>

Then Apply the following in your Style in style.xml

<style name="AppFullScreenTheme" parent="Theme.AppCompat.Light.NoActionBar">
    <item name="android:windowNoTitle">true</item>
    <item name="android:windowActionBar">false</item>
    <item name="android:windowFullscreen">true</item>
    <item name="android:windowContentOverlay">@null</item>
</style>

Mono comes with a wrapper, use theirs!

https://github.com/mono/mono/tree/master/mcs/class/Mono.Data.Sqlite/Mono.Data.Sqlite_2.0 gives code to wrap the actual SQLite dll ( http://www.sqlite.org/sqlite-shell-win32-x86-3071300.zip found on the download page http://www.sqlite.org/download.html/ ) in a .net friendly way. It works on Linux or Windows.

This seems the thinnest of all worlds, minimizing your dependence on third party libraries. If I had to do this project from scratch, this is the way I would do it.

You need the Microsoft.AspNet.WebApi.Core package.

You can see it in the .csproj file:

<Reference Include="System.Web.Http, Version=5.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35, processorArchitecture=MSIL">
  <SpecificVersion>False</SpecificVersion>
  <HintPath>..\packages\Microsoft.AspNet.WebApi.Core.5.0.0\lib\net45\System.Web.Http.dll</HintPath>
</Reference>

You can use this code to see the last modified date of a file.

DateTime dt = File.GetLastWriteTime(path);

And this code to see the creation time.

DateTime fileCreatedDate = File.GetCreationTime(@"C:\Example\MyTest.txt");

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.

In addition to all the other answers you received, I want to explain the unknown option -- o error: Your command was

$ adb shell 'su -c  mount -o rw,remount /system'

which calls su through adb. You properly quoted the whole su command in order to pass it as one argument to adb shell. However, su -c <cmd> also needs you to quote the command with arguments it shall pass to the shell's -c option. (YMMV depending on su variants.) Therefore, you might want to try

$ adb shell 'su -c "mount -o rw,remount /system"'

(and potentially add the actual device listed in the output of mount | grep system before the /system arg – see the other answers.)

In windows

netstat -ano

will list all the protocols, ports and processes listening . Use

taskkill -pid "proces to kill" /f

to kill the process listening to the port. e.g

 taskkill -pid 431 /f

You might want to push the object into the array

enter code here

var AssocArray = new Array();

AssocArray.push( "The letter A");

console.log("a = " + AssocArray[0]);

// result: "a = The letter A"

console.log( AssocArray[0]);

JSON.stringify(AssocArray);

In case of detached HEAD, commits work like normal, except no named branch gets updated. To get master branch updated with your committed changes, make a temporary branch where you are (this way the temporary branch will have all the committed changes you have made in the detached HEAD) , then switch to the master branch and merge the temporary branch with the master.

git branch  temp
git checkout master
git merge temp

Get URL from URI and use getFile() if you are not ready to use substring way of extracting file.

If your index is less than the size of your list then it does exist, possibly with null value. If index is bigger then you may call ensureCapacity() to be able to use that index.

If you want to check if a value at your index is null or not, call get()

You can use sftp to mount the remote directory on your location machine and then simply open the files using Sublime text the way you normally would.

To mount remote directory using sftp, enter the following on your Linux file manager;

sftp://user@remote_box.com:22/home/user/code_directory

It might seem slow depending on your internet speeds. But this worked for me.

As others said, it's a time change in 1927 in Shanghai.

It was 23:54:07 in Shanghai, in the local standard time, but then after 5 minutes and 52 seconds, it turned to the next day at 00:00:00, and then local standard time changed back to 23:54:08. So, that's why the difference between the two times is 343 seconds, not 1 second, as you would have expected.

The time can also mess up in other places like the US. The US has Daylight Saving Time. When the Daylight Saving Time starts the time goes forward 1 hour. But after a while, the Daylight Saving Time ends, and it goes backward 1 hour back to the standard time zone. So sometimes when comparing times in the US the difference is about 3600 seconds not 1 second.

But there is something different about these two-time changes. The latter changes continuously and the former was just a change. It didn't change back or change again by the same amount.

It's better to use UTC unless if needed to use non-UTC time like in display.

To communicate a child component with another child component I've made a method in parent which calls a method in a child with:

this.$refs.childMethod()

And from the another child I've called the root method:

this.$root.theRootMethod()

It worked for me.

I have solved this topic with the solution I have found here: http://www.blackwasp.co.uk/SwitchConfig.aspx

In short what they state there is: "by adding a post-build event.[...] We need to add the following:

if "Debug"=="$(ConfigurationName)" goto :nocopy
del "$(TargetPath).config"
copy "$(ProjectDir)\Release.config" "$(TargetPath).config"
:nocopy

select SUBSTRING_INDEX(supplier_reference,'=',-1) from ps_product;

Please use http://www.w3resource.com/mysql/string-functions/mysql-substring_index-function.php for further reference.

To read the user input and store it in a variable, for later use, you can use SQL*Plus command ACCEPT.

Accept <your variable> <variable type if needed [number|char|date]> prompt 'message'

example

accept x number prompt 'Please enter something: '

And then you can use the x variable in a PL/SQL block as follows:

declare 
  a number;
begin
  a := &x;
end;
/

Working with a string example:

accept x char prompt 'Please enter something: '

declare 
  a varchar2(10);
begin
  a := '&x';   -- for a substitution variable of char data type 
end;           -- to be treated as a character string it needs
/              -- to be enclosed with single quotation marks

For those looking to debug gradle dependencies in react-native projects, the command is (executed from projectname/android)

./gradlew app:dependencies --configuration compile

In order to execute two commands at the same time, you must put an & (ampersand) symbol between the two commands. Like so:

color 0a & start chrome.exe

Cheers!

You are overwriting your object file runexp.o by running this command :

 gcc -o runexp.o scd.o data_proc.o -lm -fopenmp

In fact, the -o is for the output file. You need to run :

gcc -o runexp.out runexp.o scd.o data_proc.o -lm -fopenmp

runexp.out will be you binary file.

In this case the user has done mistake in definition and its usage. If someone has done a typedef to a structure the same should be used without using struct following is the example.

typedef struct
{
   int a;
}studyT;

When using in a function

int main()
{
   struct studyT study; // This will give above error.
   studyT stud; // This will eliminate the above error.
   return 0;
}

'So from this discussion i am thinking this should be the code then.

The simplest way is to use IF to violate your a key constraint. This only works for INSERT IGNORE but will allow you to use constraint in a INSERT.

INSERT INTO Test (id, name) VALUES (IF(1!=0,NULL,1),'Test');

Well, Pavel was close, but there's even a more simple and elegant solution to initialize a sequential container from a c style array.

In your case:

w_ (array, std::end(array))

• array will get us a pointer to the beginning of the array (didn't catch it's name),
• std::end(array) will get us an iterator to the end of the array.

In my case (Spring 3.2.4 and Jackson 2.3.1), XML configuration for custom serializer:

<mvc:annotation-driven>
    <mvc:message-converters register-defaults="false">
        <bean class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
            <property name="objectMapper">
                <bean class="org.springframework.http.converter.json.Jackson2ObjectMapperFactoryBean">
                    <property name="serializers">
                        <array>
                            <bean class="com.example.business.serializer.json.CustomObjectSerializer"/>
                        </array>
                    </property>
                </bean>
            </property>
        </bean>
    </mvc:message-converters>
</mvc:annotation-driven>

was in unexplained way overwritten back to default by something.

This worked for me:

CustomObject.java

@JsonSerialize(using = CustomObjectSerializer.class)
public class CustomObject {

    private Long value;

    public Long getValue() {
        return value;
    }

    public void setValue(Long value) {
        this.value = value;
    }
}

CustomObjectSerializer.java

public class CustomObjectSerializer extends JsonSerializer<CustomObject> {

    @Override
    public void serialize(CustomObject value, JsonGenerator jgen,
        SerializerProvider provider) throws IOException,JsonProcessingException {
        jgen.writeStartObject();
        jgen.writeNumberField("y", value.getValue());
        jgen.writeEndObject();
    }

    @Override
    public Class<CustomObject> handledType() {
        return CustomObject.class;
    }
}

No XML configuration (<mvc:message-converters>(...)</mvc:message-converters>) is needed in my solution.

<div class="d-flex justify-content-center align-items-center container ">

label is an inline element so its width is equal to the width of the text it contains. The browser is actually displaying the label with text-align:center but since the label is only as wide as the text you don't notice.

The best thing to do is to apply a specific width to the label that is greater than the width of the content - this will give you the results you want.

Just adding another way for DataFrame expanded over all columns:

for column in df.columns:
   df = df[df[column]!=0]

Example:

def z_score(data,count):
   threshold=3
   for column in data.columns:
       mean = np.mean(data[column])
       std = np.std(data[column])
       for i in data[column]:
           zscore = (i-mean)/std
           if(np.abs(zscore)>threshold):
               count=count+1
               data = data[data[column]!=i]
   return data,count

There is definitely a way to do this -- use X() macros. These macros use the C preprocessor to construct enums, arrays and code blocks from a list of source data. You only need to add new items to the #define containing the X() macro. The switch statement would expand automatically.

Your example can be written as follows:

 // Source data -- Enum, String
 #define X_NUMBERS \
    X(ONE,   "one") \
    X(TWO,   "two") \
    X(THREE, "three")

 ...

 // Use preprocessor to create the Enum
 typedef enum {
  #define X(Enum, String)       Enum,
   X_NUMBERS
  #undef X
 } Numbers;

 ...

 // Use Preprocessor to expand data into switch statement cases
 switch(num)
 {
 #define X(Enum, String) \
     case Enum:  strcpy(num_str, String); break;
 X_NUMBERS
 #undef X

     default: return 0; break;
 }
 return 1;

There are more efficient ways (i.e. using X Macros to create an string array and enum index), but this is the simplest demo.

Late to the party, but the OP should have gone with Buildout or Virtualenv, and sidestepped the problem completely.

I am currently working on a Centos server, well, toiling away would be the proper term and I can assure everyone that the only way I am able to blink back the tears whilst using the software equivalents of fire hardened spears, is buildout.

In the pgAdmin4, Right click on table select backup like this

After that into the backup dialog there is Dump options tab into that there is section queries you can select Use Insert Commands which include all insert queries as well in the backup.

How to do it 100% through the Sourcetree GUI

(Not everyone likes doing things through the git command line interface)

Once this has been set up, you only need to do steps 7-13 from then on.

Fetch > checkout master branch > reset to their master > Push changes to server

Steps

1. In the menu toolbar at the top of the screen: "Repository" > "Repository settings"

2. "Add"

3. Go back to GitHub and copy the clone URL.

4. Paste the url into the "URL / Path" field then give it a name that makes sense. I called it "master". Do not check the "Default remote" checkbox. You will not be able to push directly to this repository.

5. Press "OK" and you should see it appear in your list of repositories now.

6. Press "OK" again and you should see it appear in your list of "Remotes".

7. Click the "Fetch" button (top left of the Source tree header area)

8. Make sure the "Fetch from all remotes" checkbox is checked and press "ok"

9. Double click on your "master" branch to check it out if it is not checked out already.

10. Find the commit that you want to reset to, if you called the repo "master" you will most likely want to find the commit with the "master/master" tag on it.

11. Right click on the commit > "Reset current branch to this commit".

12. In the dialog, set the "Using mode:" field to "Hard - discard all working copy changes" then press "OK" (make sure to put any changes that you don't want to lose onto a separate branch first).

13. Click the "Push" button (top left of the Source tree header area) to upload the changes to your copy of the repo.

Your Done!

I'd like to add one additional piece of information since the accepted answer above didn't fix my errors completely.

In my scenario, I have a parent component, which holds a child component. And that child component also contains another component.

So, my parent component's spec file need to have the declaration of the child component, AS WELL AS THE CHILD'S CHILD COMPONENT. That finally fixed the issue for me.

If you want to have more flexibility with filenames and compression options, you can use:

find /my/path/ -type f -name "*.sql" -o -name "*.log" -exec \
tar -P --transform='s@/my/path/@@g' -cf - {} + | \
pigz -9 -p 4 > myarchive.tar.gz

Step 1: find

find /my/path/ -type f -name "*.sql" -o -name "*.log" -exec

This command will look for the files you want to archive, in this case /my/path/*.sql and /my/path/*.log. Add as many -o -name "pattern" as you want.

-exec will execute the next command using the results of find: tar

Step 2: tar

tar -P --transform='s@/my/path/@@g' -cf - {} +

--transform is a simple string replacement parameter. It will strip the path of the files from the archive so the tarball's root becomes the current directory when extracting. Note that you can't use -C option to change directory as you'll lose benefits of find: all files of the directory would be included.

-P tells tar to use absolute paths, so it doesn't trigger the warning "Removing leading `/' from member names". Leading '/' with be removed by --transform anyway.

-cf - tells tar to use the tarball name we'll specify later

{} + uses everyfiles that find found previously

Step 3: pigz

pigz -9 -p 4

Use as many parameters as you want. In this case -9 is the compression level and -p 4 is the number of cores dedicated to compression. If you run this on a heavy loaded webserver, you probably don't want to use all available cores.

Step 4: archive name

> myarchive.tar.gz

Finally.

public String capitalizeFirstLetter(String original) {
    if (original == null || original.length() == 0) {
        return original;
    }
    return original.substring(0, 1).toUpperCase() + original.substring(1);
}

Just... a complete solution, I see it kind of just ended up combining what everyone else ended up posting =P.

I had to set the env variable SSL_CERT_DIR to point to my ca-bundle which was located at /etc/ssl/certs/ca-bundle.crt

I read all the comments and thought that GitHub made it too difficult for normal user to create GitHub pages until I visited GitHub theme Page where its clearly mentioned that there is a section of "GitHub Pages" under settings Page of the concerned repo where you can choose the option "use the master branch for GitHub Pages." and voilà!!...checkout that particular repo on https://username.github.io/reponame

This workaround was written in 2009 when IOS 3.0 was released. It no longer applies.

I ran into the exact same problem, in the end I had to wind up using

nameField.contentInset = UIEdgeInsetsMake(-4,-8,0,0);

where nameField is a UITextView. The font I happened to be using was Helvetica 16 point. Its only a custom solution for the particular field size I was drawing. This makes the left offset flush with the left side, and the top offset where I want it for the box its draw in.

In addition, this only seems to apply to UITextViews where you are using the default aligment, ie.

nameField.textAlignment = NSTextAlignmentLeft;

Align to the right for example and the UIEdgeInsetsMake seems to have no impact on the right edge at all.

At very least, using the .contentInset property allows you to place your fields with the "correct" positions, and accommodate the deviations without offsetting your UITextViews.

I know it's not the best solution, but the best practice:

$("#root").append(child);

setTimeout(function(){
  // Action after append
},100);

$("#myId").val() should work if myid is the select element id!

This would set the selected item: $("#myId").val('VALUE');

this looks like PHP to me. I'll delete if it's some other language.

Simply unset($arr[1]);

For a production system, you can use this configuration :

--ACCESS DB
REVOKE CONNECT ON DATABASE nova FROM PUBLIC;
GRANT  CONNECT ON DATABASE nova  TO user;

--ACCESS SCHEMA
REVOKE ALL     ON SCHEMA public FROM PUBLIC;
GRANT  USAGE   ON SCHEMA public  TO user;

--ACCESS TABLES
REVOKE ALL ON ALL TABLES IN SCHEMA public FROM PUBLIC ;
GRANT SELECT                         ON ALL TABLES IN SCHEMA public TO read_only ;
GRANT SELECT, INSERT, UPDATE, DELETE ON ALL TABLES IN SCHEMA public TO read_write ;
GRANT ALL                            ON ALL TABLES IN SCHEMA public TO admin ;

i wouldn't do it this way

I'd use name arrays in the form elements

so i'd get the layout

$_POST['field'][0]['name'] = 'value';
$_POST['field'][0]['price'] = 'value';
$_POST['field'][1]['name'] = 'value';
$_POST['field'][1]['price'] = 'value';

then you could do an array slice to get the amount you need

If a computer can run it, a suitably motivated human can reverse-engineer it.

I found that DataGridViewTextBox values and some JSON objects don't equal Null but instead are "{}" values. Comparing them to Null doesn't work but using these do the trick:

if (cell.Value is System.DBNull)

if (cell.Value == System.DBNull.Value)

A good excerpt I found concerning the difference between Null and DBNull:

Do not confuse the notion of null in an object-oriented programming language with a DBNull object. In an object-oriented programming language, null means the absence of a reference to an object. DBNull represents an uninitialized variant or nonexistent database column.

You can learn more about the DBNull class here.

For me, a hint to wrap the troubled element in another HTML tag helped. However I also needed to add a key to that HTML tag. For example:

// Didn't work
<div>
     <TroubledComponent/>
</div>

// Worked
<div key='uniqueKey'>
     <TroubledComponent/>
</div>

ActionBar ab = getActionBar();
TextView tv = new TextView(getApplicationContext());

LayoutParams lp = new RelativeLayout.LayoutParams(
        LayoutParams.MATCH_PARENT, // Width of TextView
        LayoutParams.WRAP_CONTENT);
tv.setLayoutParams(lp);
tv.setTextColor(Color.RED);
ab.setCustomView(tv);

I have tried both ways, and from the Edit|Advanced menu, and they are not doing anything to my source code. Other options like line indent are working. What could be wrong? – Chucky Jul 12 '13 at 11:06

Sometimes if it doesnt work, try to select a couple lines above and below or the whole block of code (whole function, whole cycle, whole switch, etc.), so that it knows how to indent.

Like for example if you copy/paste something into a case statement of a switch and it has wrong indentation, you need to select the text + the line with the case statement above to get it to work.

rows.RemoveAt(rows.Count - 1);

Here is the alternative solution to check whether a particular string contains some predefined string. It uses IndexOf Function:

'this is your string
Dim strMyString As String = "aaSomethingbb"

'if your string contains these strings
Dim TargetString1 As String = "Something"
Dim TargetString2 As String = "Something2"

If strMyString.IndexOf(TargetString1) <> -1 Or strMyString.IndexOf(TargetString2) <> -1 Then

End If

NOTE: This solution has been tested with Visual Studio 2010.

Small update on Marc we will have additional " , " at the end. i used stuff function to remove extra semicolon .

       SELECT STUFF((  SELECT ',' + ModuleValue AS ModuleValue
                           FROM ModuleValue WHERE ModuleID=@ModuleID
                      FOR XML PATH('') 
                     ), 1, 1, '' )

To enable your app to listen for both http and https on ports 80 and 443 respectively, do the following

Create an express app:

var express = require('express');
var app = express();

The app returned by express() is a JavaScript function. It can be be passed to Node’s HTTP servers as a callback to handle requests. This makes it easy to provide both HTTP and HTTPS versions of your app using the same code base.

You can do so as follows:

var express = require('express');
var https = require('https');
var http = require('http');
var fs = require('fs');
var app = express();

var options = {
  key: fs.readFileSync('/path/to/key.pem'),
  cert: fs.readFileSync('/path/to/cert.pem')
};

http.createServer(app).listen(80);
https.createServer(options, app).listen(443);

In Bootstrap, the .btn class has a white-space: nowrap; property, making it so that the button text won't wrap. So, after setting that to normal, and giving the button a width, the text should wrap to the next line if the text would exceed the set width.

#new-board-btn {
    white-space: normal;
}

Escaped percent sign is double percent (%%):

System.out.printf("2 out of 10 is %d%%", 20);

There's no way to guarantee that two functions will execute in sync with each other which seems to be what you want to do.

The best you can do is to split up the function into several steps, then wait for both to finish at critical synchronization points using Process.join like @aix's answer mentions.

This is better than time.sleep(10) because you can't guarantee exact timings. With explicitly waiting, you're saying that the functions must be done executing that step before moving to the next, instead of assuming it will be done within 10ms which isn't guaranteed based on what else is going on on the machine.

When you alter column datatype you need to change constraint key for every database

As written in the official instructions:

The GOPATH environment variable specifies the location of your workspace. It defaults to a directory named go inside your home directory, so $HOME/go on Unix, $home/go on Plan 9, and %USERPROFILE%\go (usually C:\Users\YourName\go) on Windows. If you would like to work in a different location, you will need to set GOPATH to the path to that directory. (Another common setup is to set GOPATH=$HOME.) Note that GOPATH must not be the same path as your Go installation.

So for example, if you are coding in Jetbrains Webstorm (using the Go plugin), you might want to set GOPATH as /Users/<user>/WebstormProjects.

In simpler words, set it to wherever you want your Go projects to reside.

Line break accepts an optional argument in brackets, a vertical length:

line 1
\\[4in]
line 2

To make this more scalable with respect to font size, you can use other lengths, such as \\[3\baselineskip], or \\[3ex].

To stick to == without consideration of the other type, the following is also possible.
type(a) == type(None)

Immutable lists are best represented through two-tuples, with None representing NIL. To allow simple formulation of such lists, you can use this function:

def mklist(*args):
    result = None
    for element in reversed(args):
        result = (element, result)
    return result

To work with such lists, I'd rather provide the whole collection of LISP functions (i.e. first, second, nth, etc), than introducing methods.

There is another library lodash, it has clone and cloneDeep.

clone will clone your object but not create a new instance for non-primitive values, instead it will use the referrence to the original object

cloneDeep will create literally new objects without having any referrence to the original object, so it more safe when you have to change the object afterwards.

Louth's answer works fine. But I don't think always return POSITION_NONE is a good idea. Because POSITION_NONE means that fragment should be destroyed and a new fragment will be created. You can check that in dataSetChanged function in the source code of ViewPager.

        if (newPos == PagerAdapter.POSITION_NONE) {
            mItems.remove(i);
            i--;
            ... not related code
            mAdapter.destroyItem(this, ii.position, ii.object);

So I think you'd better use an arraylist of weakReference to save all the fragments you have created. And when you add or remove some page, you can get the right position from your own arraylist.

 public int getItemPosition(Object object) {
    for (int i = 0; i < mFragmentsReferences.size(); i ++) {
        WeakReference<Fragment> reference = mFragmentsReferences.get(i);
        if (reference != null && reference.get() != null) {
            Fragment fragment = reference.get();
            if (fragment == object) {
                return i;
            }
        }
    }
    return POSITION_NONE;
}

According to the comments, getItemPosition is Called when the host view is attempting to determine if an item's position has changed. And the return value means its new position.

But this is not enought. We still have an important step to take. In the source code of FragmentStatePagerAdapter, there is an array named "mFragments" caches the fragments which are not destroyed. And in instantiateItem function.

if (mFragments.size() > position) {
        Fragment f = mFragments.get(position);
        if (f != null) {
            return f;
        }
    }

It returned the cached fragment directly when it find that cached fragment is not null. So there is a problem. From example, let's delete one page at position 2, Firstly, We remove that fragment from our own reference arraylist. so in getItemPosition it will return POSITION_NONE for that fragment, and then that fragment will be destroyed and removed from "mFragments".

 mFragments.set(position, null);

Now the fragment at position 3 will be at position 2. And instantiatedItem with param position 3 will be called. At this time, the third item in "mFramgents" is not null, so it will return directly. But actually what it returned is the fragment at position 2. So when we turn into page 3, we will find an empty page there.

To work around this problem. My advise is that you can copy the source code of FragmentStatePagerAdapter into your own project, and when you do add or remove operations, you should add and remove elements in the "mFragments" arraylist.

Things will be simpler if you just use PagerAdapter instead of FragmentStatePagerAdapter. Good Luck.

OP's solution to his problem, as he says, has dubious output. That code still shows confusion about representations of time. To clear up this confusion, and make code that won't lead to wrong times, consider this extension of what he did:

public static void _testDateFormatting() {
    SimpleDateFormat sdfGMT1 = new SimpleDateFormat("yyyy.MM.dd HH:mm:ss");
    sdfGMT1.setTimeZone(TimeZone.getTimeZone("GMT"));
    SimpleDateFormat sdfGMT2 = new SimpleDateFormat("yyyy.MM.dd HH:mm:ss z");
    sdfGMT2.setTimeZone(TimeZone.getTimeZone("GMT"));

    SimpleDateFormat sdfLocal1 = new SimpleDateFormat("yyyy.MM.dd HH:mm:ss");
    SimpleDateFormat sdfLocal2 = new SimpleDateFormat("yyyy.MM.dd HH:mm:ss z");

    try {
        Date d = new Date();
        String s1 = d.toString();
        String s2 = sdfLocal1.format(d);
        // Store s3 or s4 in database.
        String s3 = sdfGMT1.format(d);
        String s4 = sdfGMT2.format(d);
        // Retrieve s3 or s4 from database, using LOCAL sdf.
        String s5 = sdfLocal1.parse(s3).toString();
        //EXCEPTION String s6 = sdfLocal2.parse(s3).toString();
        String s7 = sdfLocal1.parse(s4).toString();
        String s8 = sdfLocal2.parse(s4).toString();
        // Retrieve s3 from database, using GMT sdf.
        // Note that this is the SAME sdf that created s3.
        Date d2 = sdfGMT1.parse(s3);
        String s9 = d2.toString();
        String s10 = sdfGMT1.format(d2);
        String s11 = sdfLocal2.format(d2);
    } catch (Exception e) {
        e.printStackTrace();
    }       
}

examining values in a debugger:

s1  "Mon Sep 07 06:11:53 EDT 2015" (id=831698113128)    
s2  "2015.09.07 06:11:53" (id=831698114048) 
s3  "2015.09.07 10:11:53" (id=831698114968) 
s4  "2015.09.07 10:11:53 GMT+00:00" (id=831698116112)   
s5  "Mon Sep 07 10:11:53 EDT 2015" (id=831698116944)    
s6  -- omitted, gave parse exception    
s7  "Mon Sep 07 10:11:53 EDT 2015" (id=831698118680)    
s8  "Mon Sep 07 06:11:53 EDT 2015" (id=831698119584)    
s9  "Mon Sep 07 06:11:53 EDT 2015" (id=831698120392)    
s10 "2015.09.07 10:11:53" (id=831698121312) 
s11 "2015.09.07 06:11:53 EDT" (id=831698122256) 

sdf2 and sdfLocal2 include time zone, so we can see what is really going on. s1 & s2 are at 06:11:53 in zone EDT. s3 & s4 are at 10:11:53 in zone GMT -- equivalent to the original EDT time. Imagine we save s3 or s4 in a data base, where we are using GMT for consistency, so we can have times from anywhere in the world, without storing different time zones.

s5 parses the GMT time, but treats it as a local time. So it says "10:11:53" -- the GMT time -- but thinks it is 10:11:53 in local time. Not good.

s7 parses the GMT time, but ignores the GMT in the string, so still treats it as a local time.

s8 works, because now we include GMT in the string, and the local zone parser uses it to convert from one time zone to another.

Now suppose you don't want to store the zone, you want to be able to parse s3, but display it as a local time. The answer is to parse using the same time zone it was stored in -- so use the same sdf as it was created in, sdfGMT1. s9, s10, & s11 are all representations of the original time. They are all "correct". That is, d2 == d1. Then it is only a question of how you want to DISPLAY it. If you want to display what is stored in DB -- GMT time -- then you need to format it using a GMT sdf. Ths is s10.

So here is the final solution, if you don't want to explicitly store with " GMT" in the string, and want to display in GMT format:

public static void _testDateFormatting() {
    SimpleDateFormat sdfGMT1 = new SimpleDateFormat("yyyy.MM.dd HH:mm:ss");
    sdfGMT1.setTimeZone(TimeZone.getTimeZone("GMT"));

    try {
        Date d = new Date();
        String s3 = sdfGMT1.format(d);
        // Store s3 in DB.
        // ...
        // Retrieve s3 from database, using GMT sdf.
        Date d2 = sdfGMT1.parse(s3);
        String s10 = sdfGMT1.format(d2);
    } catch (Exception e) {
        e.printStackTrace();
    }       
}

For swift

label.textAlignment = .left
label.text = "This is a Label"

    let marginTop = parseInt(bodyStyle.getPropertyValue('margin-top'), 10);
    let marginBottom = parseInt(bodyStyle.getPropertyValue('margin-bottom'), 10);
    return fullHeight - contentHeight - marginTop - marginBottom;
  }

I tested this in Firefox with Firebug using code like this:

console.time("testEquality");
var n = 0;
while (true) {
  n++;
  if (n == 100000)
    break;
}
console.timeEnd("testEquality");

and

console.time("testTypeEquality");
var n = 0;
while (true) {
  n++;
  if (n === 100000)
    break;
}
console.timeEnd("testTypeEquality");

My results (tested five times each and averaged):

==: 115.2
===: 114.4

So I'd say that the miniscule difference (this is over 100000 iterations, remember) is negligible. Performance isn't a reason to do ===. Type safety (well, as safe as you're going to get in JavaScript), and code quality is.

I came across the situation where I met a condition that broke the loop, however the code after the .each() function still executed. I then set a flag to "true" with an immediate check for the flag after the .each() function to ensure the code that followed was not executed.

$('.groupName').each(function() {
    if($(this).text() == groupname){
        alert('This group already exists');
        breakOut = true;
        return false;
    }
});
if(breakOut) {
    breakOut = false;
    return false;
} 

This was how I solved it:

        largestSmallestNum.findLargestSmalestNo();
    }
}

You can use the shell for this purpose.

Set shl = CreateObject("WScript.Shell") 
shl.Run "cmd mkdir YourDir" & copy "

To pass a NULL to MySQL, you do just that.

INSERT INTO table (field,field2) VALUES (NULL,3)

So, in your code, check if $intLat, $intLng are empty, if they are, use NULL instead of '$intLat' or '$intLng'.

$intLat = !empty($intLat) ? "'$intLat'" : "NULL";
$intLng = !empty($intLng) ? "'$intLng'" : "NULL";

$query = "INSERT INTO data (notes, id, filesUploaded, lat, lng, intLat, intLng)
          VALUES ('$notes', '$id', TRIM('$imageUploaded'), '$lat', '$long', 
                  $intLat, $intLng)";

The jsonlite package is easy to use and tries to convert json into data frames.

Example:

library(jsonlite)

# url with some information about project in Andalussia
url <- 'http://www.juntadeandalucia.es/export/drupaljda/ayudas.json'

# read url and convert to data.frame
document <- fromJSON(txt=url)

Although for Razor you can of course just generate the options by looping through TimeZoneInfo.GetSystemTimeZones()

This task can be accomplished using one of the android's main building block named as Intents and One of the methods public void startActivity (Intent intent) which belongs to your Activity class.

An intent is an abstract description of an operation to be performed. It can be used with startActivity to launch an Activity, broadcastIntent to send it to any interested BroadcastReceiver components, and startService(Intent) or bindService(Intent, ServiceConnection, int) to communicate with a background Service.

An Intent provides a facility for performing late runtime binding between the code in different applications. Its most significant use is in the launching of activities, where it can be thought of as the glue between activities. It is basically a passive data structure holding an abstract description of an action to be performed.

Refer the official docs -- http://developer.android.com/reference/android/content/Intent.html

public void startActivity (Intent intent) -- Used to launch a new activity.

So suppose you have two Activity class --

1. PresentActivity -- This is your current activity from which you want to go the second activity.

2. NextActivity -- This is your next Activity on which you want to move.

So the Intent would be like this

Intent(PresentActivity.this, NextActivity.class)

Finally this will be the complete code

public class PresentActivity extends Activity {
  protected void onCreate(Bundle icicle) {
    super.onCreate(icicle);

    setContentView(R.layout.content_layout_id);

    final Button button = (Button) findViewById(R.id.button_id);
    button.setOnClickListener(new View.OnClickListener() {
            public void onClick(View v) {
              // Perform action on click   
              Intent activityChangeIntent = new Intent(PresentActivity.this, NextActivity.class);

              // currentContext.startActivity(activityChangeIntent);

              PresentActivity.this.startActivity(activityChangeIntent);
            }
          });
  }
}

just try this way

  String strFilter = "_id=" + Id;
  ContentValues args = new ContentValues();
  args.put(KEY_TITLE, title);
  myDB.update("titles", args, strFilter, null);**

I am not sure if intercepting function keys is possible, but I would avoid using function keys all together. Function keys are used by browsers to perform a variety of tasks, some of them quite common. For example, in Firefox on Linux, at least six or seven of the function keys are reserved for use by the browser:

• F1 (Help),
• F3 (Search),
• F5 (Refresh),
• F6 (focus address bar),
• F7 (caret browsing mode),
• F11 (full screen mode), and
• F12 (used by several add-ons, including Firebug)

The worst part is that different browsers on different operating systems use different keys for different things. That's a lot of differences to account for. You should stick to safer, less commonly used key combinations.

Following these steps solved my problem.

1. Delete node_modules directory
2. Delete package-lock.json file
3. Start command prompt as Administrator <- important
4. Run npm install
5. Run npm run dev

I had faced the same issue, somewhere deep in our code we had this pseudocode:

• create an iframe

• onload of iframe submit a form

• After 2 seconds, remove the iframe

thus, when the server takes more than 2 seconds to respond the iframe to which the server was writing the response to, was removed, but the response was still to be written , but there was no iframe to write , thus chrome cancelled the request, thus to avoid this I made sure that the iframe is removed only after the response is over, or you can change the target to "_blank". Thus one of the reason is: when the resource(iframe in my case) that you are writing something in, is removed or deleted before you stop writing to it, the request will be cancelled

Your method signature is:

- (void) myTest:(NSString *)

withAString happens to be the parameter (the name is misleading, it looks like it is part of the selector's signature).

If you call the function in this manner:

[self performSelector:@selector(myTest:) withObject:myString];

It will work.

But, as the other posters have suggested, you may want to rename the method:

- (void)myTestWithAString:(NSString*)aString;

And call:

[self performSelector:@selector(myTestWithAString:) withObject:myString];

The return statement you have is stuck in the inner function, so it won't return from the outer function. You just need a little more code:

function getMachine(color, qty) {
    var returnValue = null;
    $("#getMachine li").each(function() {
        var thisArray = $(this).text().split("~");
        if(thisArray[0] == color&& qty>= parseInt(thisArray[1]) && qty<= parseInt(thisArray[2])) {
            returnValue = thisArray[3];
            return false; // this breaks out of the each
        }
    });
    return returnValue;
}

var retval = getMachine(color, qty);

random.randrange(0,2) this works!

The following can be saved to the shell script to do the job:

For example:

remote="origin"

if [ "$#" -eq 0 ] # if there are no arguments, just quit
then
    echo "Usage: $0 oldName newName or $0 newName" >&2
    exit 1
elif
    [ "$#" -eq 1 ] # if only one argument is given, rename current branch
then 
    oldBranchName="$(git branch | grep \* | cut -d ' ' -f2)" #save current branch name
    newBranchName=$1
else
    oldBranchName=$1
    newBranchName=$2
fi

git branch -m $oldBranchName $newBranchName

git push $remote :$oldBranchName #delete old branch on remote
git push --set-upstream $remote $newBranchName # add new branch name on remote and track it

Please note that here default remote name "origin" is hard-coded, you can extend the script to make if configurable!

Then this script can be used with bash aliases, git aliases or in, for example, sourcetree custom actions.

Another one-liner:

Array.prototype.map.call([]+Array(5+1),function(){ return '2'; })

Use the Controller's Redirect() method.

public ActionResult YourAction()
{
    // ...
    return Redirect("http://www.example.com");
}

Update

You can't directly perform a server side redirect from an ajax response. You could, however, return a JsonResult with the new url and perform the redirect with javascript.

public ActionResult YourAction()
{
    // ...
    return Json(new {url = "http://www.example.com"});
}

$.post("@Url.Action("YourAction")", function(data) {
    window.location = data.url;
});

This project should be helpful - maps touch events to click events in a way that allows jQuery UI to work on iPad and iPhone without any changes. Just add the JS to any existing project.

Just came accross this use case. I implemented gens's answer, adding a recursive approach for handling values that are also dicts:

def mutate_dict_in_place(f, d):
    for k, v in d.iteritems():
        if isinstance(v, dict):
            mutate_dict_in_place(f, v)
        else:
            d[k] = f(v)

# Exemple handy usage
def utf8_everywhere(d):
    mutate_dict_in_place((
        lambda value:
            value.decode('utf-8')
            if isinstance(value, bytes)
            else value
        ),
        d
    )

my_dict = {'a': b'byte1', 'b': {'c': b'byte2', 'd': b'byte3'}}
utf8_everywhere(my_dict)
print(my_dict)

This can be useful when dealing with json or yaml files that encode strings as bytes in Python 2

Jackson has to know in what order to pass fields from a JSON object to the constructor. It is not possible to access parameter names in Java using reflection - that's why you have to repeat this information in annotations.

Just leave out the "dot-slash" ./:

D:\Gesture Recognition\Gesture Recognition\Debug>"Gesture Recognition.exe"

The first server block in the nginx config is the default for all requests that hit the server for which there is no specific server block.

So in your config, assuming your real domain is REAL.COM, when a user types that in, it will resolve to your server, and since there is no server block for this setup, the server block for FAKE.COM, being the first server block (only server block in your case), will process that request.

This is why proper Nginx configs have a specific server block for defaults before following with others for specific domains.

# Default server
server {
    return 404;
}

server {
    server_name domain_1;
    [...]
}

server {
    server_name domain_2;
    [...]
}

etc

** EDIT **

It seems some users are a bit confused by this example and think it is limited to a single conf file etc.

Please note that the above is a simple example for the OP to develop as required.

I personally use separate vhost conf files with this as so (CentOS/RHEL):

http {
    [...]
    # Default server
    server {
        return 404;
    }
    # Other servers
    include /etc/nginx/conf.d/*.conf;
}

/etc/nginx/conf.d/ will contain domain_1.conf, domain_2.conf... domain_n.conf which will be included after the server block in the main nginx.conf file which will always be the first and will always be the default unless it is overridden it with the default_server directive elsewhere.

The alphabetical order of the file names of the conf files for the other servers becomes irrelevant in this case.

In addition, this arrangement gives a lot of flexibility in that it is possible to define multiple defaults.

In my specific case, I have Apache listening on Port 8080 on the internal interface only and I proxy PHP and Perl scripts to Apache.

However, I run two separate applications that both return links with ":8080" in the output html attached as they detect that Apache is not running on the standard Port 80 and try to "help" me out.

This causes an issue in that the links become invalid as Apache cannot be reached from the external interface and the links should point at Port 80.

I resolve this by creating a default server for Port 8080 to redirect such requests.

http {
    [...]
    # Default server block for undefined domains
    server {
        listen 80;
        return 404;
    }
    # Default server block to redirect Port 8080 for all domains
    server {
        listen my.external.ip.addr:8080;
        return 301 http://$host$request_uri;
    }
    # Other servers
    include /etc/nginx/conf.d/*.conf;
}

As nothing in the regular server blocks listens on Port 8080, the redirect default server block transparently handles such requests by virtue of its position in nginx.conf.

I actually have four of such server blocks and this is a simplified use case.

Check the latest version of Has on Intel website and install it. Let the ram in recommended size "preset 2048", then try to run the app. Things should work fine.

Note: In hindsight this was a quick and dirty answer, and may not work in all situations. To have a reliable solution, see Tim Down's answer (copy pasting that here as this answer is still getting views and upvotes):

You can't do this reliably with the keyup event. If you want to know something about the character that was typed, you have to use the keypress event instead.

The following example will work all the time in most browsers but there are some edge cases that you should be aware of. For what is in my view the definitive guide on this, see http://unixpapa.com/js/key.html.

$("input").keypress(function(e) {
    if (e.which !== 0) {
        alert("Character was typed. It was: " + String.fromCharCode(e.which));
    }
});

keyup and keydown give you information about the physical key that was pressed. On standard US/UK keyboards in their standard layouts, it looks like there is a correlation between the keyCode property of these events and the character they represent. However, this is not reliable: different keyboard layouts will have different mappings.

The following was the original answer, but is not correct and may not work reliably in all situations.

To match the keycode with a word character (eg., a would match. space would not)

$("input").keyup(function(event)
{ 
    var c= String.fromCharCode(event.keyCode);
    var isWordcharacter = c.match(/\w/);
}); 

Ok, that was a quick answer. The approach is the same, but beware of keycode issues, see this article in quirksmode.

id is a newly generated ObjectId.

To allow Windows installers to find the installed Python directory in Windows 7, OR, change which Python installation to install an installer into, add the installed path into the InstallPath registry key's (Default) value:

Where "X" is the Python version (that is, 2.5, 2.6, or 2.7).

The HttpRequest class represents the request made to the server and has various properties associated with it, such as QueryString.

The ASP.NET run-time parses a request to the server and populates this information for you.

Read HttpRequest Properties for a list of all the potential properties that get populated on you behalf by ASP.NET.

Note: not all properties will be populated, for instance if your request has no query string, then the QueryString will be null/empty. So you should check to see if what you expect to be in the query string is actually there before using it like this:

if (!String.IsNullOrEmpty(Request.QueryString["pID"]))
{
    // Query string value is there so now use it
    int thePID = Convert.ToInt32(Request.QueryString["pID"]);
}

For grabbing fragments out of a ViewPager there are a lot of answers on here and on other related SO threads / blogs. Everyone I have seen is broken, and they generally seem to fall into one of the two types listed below. There are some other valid solutions if you only want to grab the current fragment, like this other answer on this thread.

If using FragmentPagerAdapter see below. If using FragmentStatePagerAdapter its worth looking at this. Grabbing indexes that are not the current one in a FragmentStateAdapter is not as useful as by the nature of it these will be completely torn down went out of view / out of offScreenLimit bounds.

THE UNHAPPY PATHS

Wrong: Maintain your own internal list of fragments, added to when FragmentPagerAdapter.getItem() is called

• Usually using a SparseArray or Map
• Not one of the many examples I have seen accounts for lifecycle events so this solution is fragile. As getItem is only called the first time a page is scrolled to (or obtained if your ViewPager.setOffscreenPageLimit(x) > 0) in the ViewPager, if the hosting Activity / Fragment is killed or restarted then the internal SpaseArray will be wiped out when the custom FragmentPagerActivity is recreated, but behind the scenes the ViewPagers internal fragments will be recreated, and getItem will NOT be called for any of the indexes, so the ability to get a fragment from index will be lost forever. You can account for this by saving out and restoring these fragment references via FragmentManager.getFragment() and putFragment but this starts to get messy IMHO.

Wrong: Construct your own tag id matching what is used under the hood in FragmentPagerAdapter and use this to retrieve the page Fragments from the FragmentManager

• This is better insomuch as it copes with the losing-fragment-references problem in the first internal-array solution, but as rightly pointed out in the answers above and elsewhere on the net - it feels hacky as its a private method internal to ViewPager that could change at any time or for any OS version.

The method thats recreated for this solution is

private static String makeFragmentName(int viewId, long id) {
    return "android:switcher:" + viewId + ":" + id;
}

A HAPPY PATH: ViewPager.instantiateItem()

A similar approach to getItem() above but non-lifecycle-breaking is to this is to hook into instantiateItem() instead of getItem() as the former will be called everytime that index is created / accessed. See this answer

A HAPPY PATH: Construct your own FragmentViewPager

Construct your own FragmentViewPager class from the source of the latest support lib and change the method used internally to generate the fragment tags. You can replace it with the below. This has the advantage that you know the tag creation will never change and your not relying on a private api / method, which is always dangerous.

/**
 * @param containerViewId the ViewPager this adapter is being supplied to
 * @param id pass in getItemId(position) as this is whats used internally in this class
 * @return the tag used for this pages fragment
 */
public static String makeFragmentName(int containerViewId, long id) {
    return "android:switcher:" + containerViewId + ":" + id;
}

Then as the doc says, when you want to grab a fragment used for an index just call something like this method (which you can put in the custom FragmentPagerAdapter or a subclass) being aware the result may be null if getItem has not yet been called for that page i.e. its not been created yet.

/**
 * @return may return null if the fragment has not been instantiated yet for that position - this depends on if the fragment has been viewed
 * yet OR is a sibling covered by {@link android.support.v4.view.ViewPager#setOffscreenPageLimit(int)}. Can use this to call methods on
 * the current positions fragment.
 */
public @Nullable Fragment getFragmentForPosition(int position)
{
    String tag = makeFragmentName(mViewPager.getId(), getItemId(position));
    Fragment fragment = getSupportFragmentManager().findFragmentByTag(tag);
    return fragment;
}

This is a simple solution and solves the issues in the other two solutions found everywhere on the web

You have some files locally that need to be merged before you can pull. You could checkout the files and then pull to overwrite your local files.

git checkout app/config/app.php app/config/database.php app/routes.php
git pull origin master

This worked for me on my Oracle database:

SELECT   'GRANT SELECT, insert, update, delete ON mySchema.' || TABLE_NAME || ' to myUser;'
FROM     user_tables
where table_name like 'myTblPrefix%'

Then, copy the results, paste them into your editor, then run them like a script.

You could also write a script and use "Execute Immediate" to run the generated SQL if you don't want the extra copy/paste steps.

please don't use a global var for this - store the prev value at the data here is an example: http://jsbin.com/uqupu3/2/edit

the code for ref:

$(document).ready(function(){
  var sel = $("#sel");
  sel.data("prev",sel.val());

  sel.change(function(data){
     var jqThis = $(this);
     alert(jqThis.data("prev"));
     jqThis.data("prev",jqThis.val());
  });
});

just saw that you have many selects on page - this approach will also work for you since for each select you will store the prev value on the data of the select

It's plain and simple.

• use of span does not affect the layout because it's inline(in line (one should not confuse because things could be wrapped))
• use of div affects the layout, the content inside appears in the new line(block element), when the element you wanna add has no special semantic meaning and you want it to appear in new line use <div>.

In the special case: "All elements of List1 goes to a new List2": (e.g. a string list)

List<string> list2 = new List<string>(list1);

In this case, list2 is generated with all elements from list1.

If you've copied this directly, then:

should be

->setCellValue('B2', 'Ackermann') 

In answer to your question:

Get the data that you want from limesurvey, and use setCellValue() to store those data values in the cells where you want to store it.

The Quadratic.php example file in /Tests might help as a starting point: it takes data from an input form and sets it to cells in an Excel workbook.

EDIT

An extremely simplistic example:

// Create your database query
$query = "SELECT * FROM myDataTable";  

// Execute the database query
$result = mysql_query($query) or die(mysql_error());

// Instantiate a new PHPExcel object
$objPHPExcel = new PHPExcel(); 
// Set the active Excel worksheet to sheet 0
$objPHPExcel->setActiveSheetIndex(0); 
// Initialise the Excel row number
$rowCount = 1; 
// Iterate through each result from the SQL query in turn
// We fetch each database result row into $row in turn
while($row = mysql_fetch_array($result)){ 
    // Set cell An to the "name" column from the database (assuming you have a column called name)
    //    where n is the Excel row number (ie cell A1 in the first row)
    $objPHPExcel->getActiveSheet()->SetCellValue('A'.$rowCount, $row['name']); 
    // Set cell Bn to the "age" column from the database (assuming you have a column called age)
    //    where n is the Excel row number (ie cell A1 in the first row)
    $objPHPExcel->getActiveSheet()->SetCellValue('B'.$rowCount, $row['age']); 
    // Increment the Excel row counter
    $rowCount++; 
} 

// Instantiate a Writer to create an OfficeOpenXML Excel .xlsx file
$objWriter = new PHPExcel_Writer_Excel2007($objPHPExcel); 
// Write the Excel file to filename some_excel_file.xlsx in the current directory
$objWriter->save('some_excel_file.xlsx'); 

EDIT #2

Using your existing code as the basis

// Instantiate a new PHPExcel object 
$objPHPExcel = new PHPExcel();  
// Set the active Excel worksheet to sheet 0 
$objPHPExcel->setActiveSheetIndex(0);  
// Initialise the Excel row number 
$rowCount = 1;  

//start of printing column names as names of MySQL fields  
$column = 'A';
for ($i = 1; $i < mysql_num_fields($result); $i++)  
{
    $objPHPExcel->getActiveSheet()->setCellValue($column.$rowCount, mysql_field_name($result,$i));
    $column++;
}
//end of adding column names  

//start while loop to get data  
$rowCount = 2;  
while($row = mysql_fetch_row($result))  
{  
    $column = 'A';
    for($j=1; $j<mysql_num_fields($result);$j++)  
    {  
        if(!isset($row[$j]))  
            $value = NULL;  
        elseif ($row[$j] != "")  
            $value = strip_tags($row[$j]);  
        else  
            $value = "";  

        $objPHPExcel->getActiveSheet()->setCellValue($column.$rowCount, $value);
        $column++;
    }  
    $rowCount++;
} 


// Redirect output to a client’s web browser (Excel5) 
header('Content-Type: application/vnd.ms-excel'); 
header('Content-Disposition: attachment;filename="Limesurvey_Results.xls"'); 
header('Cache-Control: max-age=0'); 
$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5'); 
$objWriter->save('php://output');

If you don't wish to mess with IFS (perhaps for the code within the loop) this might help.

If know that your string will not have whitespace, you can substitute the ';' with a space and use the for/in construct:

#local str
for str in ${STR//;/ } ; do 
   echo "+ \"$str\""
done

But if you might have whitespace, then for this approach you will need to use a temp variable to hold the "rest" like this:

#local str rest
rest=$STR
while [ -n "$rest" ] ; do
   str=${rest%%;*}  # Everything up to the first ';'
   # Trim up to the first ';' -- and handle final case, too.
   [ "$rest" = "${rest/;/}" ] && rest= || rest=${rest#*;}
   echo "+ \"$str\""
done

Use Convert.TryFromBase64String from C# 7.2

public static bool IsBase64String(string base64)
{
   Span<byte> buffer = new Span<byte>(new byte[base64.Length]);
   return Convert.TryFromBase64String(base64, buffer , out int bytesParsed);
}

Try out this

var str ="{ "name" : "user"}";
var jsonData = JSON.parse(str);     
console.log(jsonData.name)

//Array Object

str ="[{ "name" : "user"},{ "name" : "user2"}]";
jsonData = JSON.parse(str);     
console.log(jsonData[0].name)

You actually do not want to get the path to your main class. According to your example you want to get the current working directory, i.e. directory where your program started. In this case you can just say new File(".").getAbsolutePath()

You can simply pass the functions as a list:

In [20]: df.groupby("dummy").agg({"returns": [np.mean, np.sum]})
Out[20]:         
           mean       sum
dummy                    
1      0.036901  0.369012

or as a dictionary:

In [21]: df.groupby('dummy').agg({'returns':
                                  {'Mean': np.mean, 'Sum': np.sum}})
Out[21]: 
        returns          
           Mean       Sum
dummy                    
1      0.036901  0.369012

I would handle this in the parent form. You can notify the other form that it needs to modify itself through an event.

No CSS required. This should look fine on your page. You can set col-md-* as per your needs

I would like to point out that if you can't find "Link Binaries With Libraries" in your build phases tab click the "Add build phase" button in the lower right corner.

fields() and fieldNames() both were not working for me. And I had to spend quite sometime to find a way to iterate over the keys. There are two ways by which it can be done.

One is by converting it into a map (takes up more space):

ObjectMapper mapper = new ObjectMapper();
Map<String, Object> result = mapper.convertValue(jsonNode, Map.class);
for (String key : result.keySet())
{
    if(key.equals(foo))
    {
        //code here
    }
}

Another, by using a String iterator:

Iterator<String> it = jsonNode.getFieldNames();
while (it.hasNext())
{
    String key = it.next();
    if (key.equals(foo))
    {
         //code here
    }
}

I have also encountered this error . Just i opened the new window ie Window -> New Window in eclipse .Then , I closed my old window. This solved my problem.

var maxAge = list.Max(x => x.Age);

In java8 IntSteam stream can be boxed to stream of Integers.

public static Iterable<Integer> toIterable(int[] ints) {
    return IntStream.of(ints).boxed().collect(Collectors.toList());
}

I think performance matters based on the size of the array.

You need to do something with the return value...

import java.util.Arrays;

public class trial1{

    public static void main(String[] args){
        int[] B = numbers();
        System.out.println(Arrays.toString(B));
    }

    public static int[] numbers(){
        int[] A = {1,2,3};
        return A;
    }
}

In JavaScript 1.6, you can use Array.every:

function AllTheSame(array) {
    var first = array[0];
    return array.every(function(element) {
        return element === first;
    });
}

You probably need some sanity checks, e.g. when the array has no elements. (Also, this won't work when all elements are NaN since NaN !== NaN, but that shouldn't be an issue... right?)

To see just the symlinks themselves, you can use

find -L /path/to/dir/ -xtype l 

while if you want to see also which files they target, just append an ls

find -L /path/to/dir/ -xtype l -exec ls -al {} \;

Build.VERSION_CODES.LOLLIPOP should now be changed to BuildVersionCodes.Lollipop i.e:

if (Build.VERSION.SdkInt >= BuildVersionCodes.Lollipop) {
    this.Control.Background = this.Resources.GetDrawable(Resource.Drawable.AddBorder, Context.Theme);
} else {
    this.Control.Background = this.Resources.GetDrawable(Resource.Drawable.AddBorder);
}

You can't pass a parameter in a @selector().

It looks like you're trying to implement a callback. The best way to do that would be something like this:

[object setCallbackObject:self withSelector:@selector(myMethod:)];

Then in your object's setCallbackObject:withSelector: method: you can call your callback method.

-(void)setCallbackObject:(id)anObject withSelector:(SEL)selector {
    [anObject performSelector:selector];
}

Use FirstOrDefault or a foreach loop as already mentioned. Manually fetching an enumerator and calling Current should be avoided. foreach will dispose your enumerator for you if it implements IDisposable. When calling MoveNext and Current you have to dispose it manually (if aplicable).

Try this:

var body = document.getElementsByTagName('BODY')[0];
// CONDITION DOES NOT WORK
if ((body && body.readyState == 'loaded') || (body &&  body.readyState == 'complete') ) {
    DoStuffFunction();
} else {
    // CODE BELOW WORKS
    if (window.addEventListener) {
        window.addEventListener('load', DoStuffFunction, false);
    } else {
        window.attachEvent('onload',DoStuffFunction);
    }
}

my use case was slight different. I had to construct a query where more then 20 fields were dynamic. I followed this approach of using format method

query = "insert into {0}({1},{2},{3}) values({4}, {5}, {6})"
query.format('users','name','age','dna','suzan',1010,'nda')

this was comparatively simpler for me instead of using + or other ways

Create system user some_user if it doesn't exist

if [[ $(getent passwd some_user) = "" ]]; then
    sudo adduser --no-create-home --force-badname --disabled-login --disabled-password --system some_user
fi

public static bool CompareDateTimes(this DateTime firstDate, DateTime secondDate) 
{
   return firstDate.Day == secondDate.Day && firstDate.Month == secondDate.Month && firstDate.Year == secondDate.Year;
}

I'm using this tutorial and it works nicely for my application.

In my activity I put this code:

GPSTracker tracker = new GPSTracker(this);
    if (!tracker.canGetLocation()) {
        tracker.showSettingsAlert();
    } else {
        latitude = tracker.getLatitude();
        longitude = tracker.getLongitude();
    }

also check if your emulator runs with Google API

Make sure you put your on('shown.bs.modal') before instantiating the modal to pop up

$("#myModal").on("shown.bs.modal", function () { 
    alert('Hi');
});
$("#myModal").modal('show'); //This can also be $("#myModal").modal({ show: true });

or

$("#myModal").on("shown.bs.modal", function () { 
    alert('Hi');
}).modal('show');

To focus on a field, it is better to use the shown.bs.modal in stead of show.bs.modal but maybe for other reasons you want to hide something the the background or set something right before the modal starts showing, use the show.bs.modal function.

1. Extend "LinearLayout" class and override the necessary functions
2. Create an instance of the above class in your fragment or activity
3. Call "recyclerView.smoothScrollToPosition(targetPosition)

CustomLinearLayout.kt :

class CustomLayoutManager(private val context: Context, layoutDirection: Int):
  LinearLayoutManager(context, layoutDirection, false) {

    companion object {
      // This determines how smooth the scrolling will be
      private
      const val MILLISECONDS_PER_INCH = 300f
    }

    override fun smoothScrollToPosition(recyclerView: RecyclerView, state: RecyclerView.State, position: Int) {

      val smoothScroller: LinearSmoothScroller = object: LinearSmoothScroller(context) {

        fun dp2px(dpValue: Float): Int {
          val scale = context.resources.displayMetrics.density
          return (dpValue * scale + 0.5f).toInt()
        }

        // change this and the return super type to "calculateDyToMakeVisible" if the layout direction is set to VERTICAL
        override fun calculateDxToMakeVisible(view: View ? , snapPreference : Int): Int {
          return super.calculateDxToMakeVisible(view, SNAP_TO_END) - dp2px(50f)
        }

        //This controls the direction in which smoothScroll looks for your view
        override fun computeScrollVectorForPosition(targetPosition: Int): PointF ? {
          return this @CustomLayoutManager.computeScrollVectorForPosition(targetPosition)
        }

        //This returns the milliseconds it takes to scroll one pixel.
        override fun calculateSpeedPerPixel(displayMetrics: DisplayMetrics): Float {
          return MILLISECONDS_PER_INCH / displayMetrics.densityDpi
        }
      }
      smoothScroller.targetPosition = position
      startSmoothScroll(smoothScroller)
    }
  }

Note: The above example is set to HORIZONTAL direction, you can pass VERTICAL/HORIZONTAL during initialization.

If you set the direction to VERTICAL you should change the "calculateDxToMakeVisible" to "calculateDyToMakeVisible" (also mind the supertype call return value)

Activity/Fragment.kt :

...
smoothScrollerLayoutManager = CustomLayoutManager(context, LinearLayoutManager.HORIZONTAL)
recyclerView.layoutManager = smoothScrollerLayoutManager
.
.
.
fun onClick() {
  // targetPosition passed from the adapter to activity/fragment
  recyclerView.smoothScrollToPosition(targetPosition)
}

I had the same problem, and I felt on your post.

I think the easiest way to solve this issue is by using redis Hashtable.

It allows you to save a Hash, with different fields and values associated with every field.

To get all the fiels and values client.HGETALLL does the trick. It returns an array of

all the fields followed by their values.

More informations here https://redis.io/commands/hgetall

By default X-Frame-Options is set to denied, to prevent clickjacking attacks. To override this, you can add the following into your spring security config

<http>    
    <headers>
        <frame-options policy="SAMEORIGIN"/>
    </headers>
</http>

Here are available options for policy

• DENY - is a default value. With this the page cannot be displayed in a frame, regardless of the site attempting to do so.
• SAMEORIGIN - I assume this is what you are looking for, so that the page will be (and can be) displayed in a frame on the same origin as the page itself
• ALLOW-FROM - Allows you to specify an origin, where the page can be displayed in a frame.

For more information take a look here.

And here to check how you can configure the headers using either XML or Java configs.

Note, that you might need also to specify appropriate strategy, based on needs.

When granting a user access to a database there are a few considerations to be made with advantages and disadvantages in terms of usability and security. Here we have two options for authenticating and granting permission to users. The first is by giving everyone the sa (systems admin) account access and then restricting the permissions manually by retaining a list of the users in which you can grant or deny permissions as needed. This is also known as the SQL authentication method. There are major security flaws in this method, as listed below. The second and better option is to have the Active Directory (AD) handle all the necessary authentication and authorization, also known as Windows authentication. Once the user logs in to their computer the application will connect to the database using those Windows login credentials on the operating system.

The major security issue with using the SQL option is that it violates the principle of least privilege (POLP) which is to only give the user the absolutely necessary permissions they need and no more. By using the sa account you present serious security flaws. The POLP is violated because when the application uses the sa account they have access to the entire database server. Windows authentication on the other hand follows the POLP by only granting access to one database on the server.

The second issue is that there is no need for every instance of the application to have the admin password. This means any application is a potential attack point for the entire server. Windows only uses the Windows credentials to login to the SQL Server. The Windows passwords are stored in a repository as opposed to the SQL database instance itself and the authentication takes place internally within Windows without having to store sa passwords on the application.

A third security issue arises by using the SQL method involves passwords. As presented on the Microsoft website and various security forums, the SQL method doesn’t’ enforce password changing or encryption, rather they are sent as clear text over the network. And the SQL method doesn’t lockout after failing attempts thus allowing a prolonged attempt to break in. Active Directory however, uses Kerberos protocol to encrypt passwords while employing as well a password change system and lockout after failing attempts.

There are efficiency disadvantages as well. Since you will be requiring the user to enter the credentials every time they want to access the database users may forget their credentials.

If a user being removed you would have to remove his credentials from every instance of the application. If you have to update the sa admin password you would have to update every instance of the SQL server. This is time consuming and unsafe, it leaves open the possibility of a dismissed user retaining access to the SQL Server. With the Windows method none of these concerns arise. Everything is centralized and handled by the AD.

The only advantages of using the SQL method lie in its flexibility. You are able to access it from any operating system and network, even remotely. Some older legacy systems as well as some web-based applications may only support sa access.

The AD method also provides time-saving tools such as groups to make it easier to add and remove users, and user tracking ability.

Even if you manage to correct these security flaws in the SQL method, you would be reinventing the wheel. When considering the security advantages provided by Windows authentication, including password policies and following the POLP, it is a much better choice over the SQL authentication. Therefore it is highly recommended to use the Windows authentication option.

MSSQL uses regular XPath rules as follows:

• nodename Selects all nodes with the name "nodename"
• / Selects from the root node
• // Selects nodes in the document from the current node that match the selection no matter where they are
• . Selects the current node
• .. Selects the parent of the current node
• @ Selects attributes

If I understand the question, you may interested in this example in the Matplotlib gallery.

Yann's comment above provides a similar example.

Edit - Link above fixed. Corresponding code copied from the Matplotlib gallery:

from mpl_toolkits.axes_grid1 import host_subplot
import mpl_toolkits.axisartist as AA
import matplotlib.pyplot as plt

host = host_subplot(111, axes_class=AA.Axes)
plt.subplots_adjust(right=0.75)

par1 = host.twinx()
par2 = host.twinx()

offset = 60
new_fixed_axis = par2.get_grid_helper().new_fixed_axis
par2.axis["right"] = new_fixed_axis(loc="right", axes=par2,
                                        offset=(offset, 0))

par2.axis["right"].toggle(all=True)

host.set_xlim(0, 2)
host.set_ylim(0, 2)

host.set_xlabel("Distance")
host.set_ylabel("Density")
par1.set_ylabel("Temperature")
par2.set_ylabel("Velocity")

p1, = host.plot([0, 1, 2], [0, 1, 2], label="Density")
p2, = par1.plot([0, 1, 2], [0, 3, 2], label="Temperature")
p3, = par2.plot([0, 1, 2], [50, 30, 15], label="Velocity")

You can't declare an extern local method inside of a method, or any other method with an attribute. Move your DLL import into the class:

using System.Runtime.InteropServices;


public class WindowHandling
{
    [DllImport("User32.dll")]
    public static extern int SetForegroundWindow(IntPtr point);

    public void ActivateTargetApplication(string processName, List<string> barcodesList)
    {
        Process p = Process.Start("notepad++.exe");
        p.WaitForInputIdle();
        IntPtr h = p.MainWindowHandle;
        SetForegroundWindow(h);
        SendKeys.SendWait("k");
        IntPtr processFoundWindow = p.MainWindowHandle;
    }
}

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");
}

After PHP 5 you can use this: echo date("c"); form ISO 8601 formatted datetime.

http://ideone.com/nD7piL

Note for comments:

Regarding to this, both of these expressions are valid for timezone, for basic format: ±[hh]:[mm], ±[hh][mm], or ±[hh].

But note that, +0X:00 is correct, and +0X00 is incorrect for extended usage. So it's better to use date("c"). A similar discussion here.

I create color.xml file, for naming my color name (black, white...)

 <?xml version="1.0" encoding="utf-8"?>
 <resources>
    <color name="white">#ffffff</color>
    <color name="black">#000000</color>
 </resources>

And in your EditText, set color

<EditText
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="asdsadasdasd"
        android:textColor="@color/black"
        android:background="@color/white"
        />

or use style in you style.xml:

<style name="EditTextStyleWhite" parent="android:style/Widget.EditText">
    <item name="android:textColor">@color/black</item>
    <item name="android:background">@color/white</item>
</style>

and add ctreated style to EditText:

 <EditText
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="asdsadasdasd"
        style="@style/EditTextStyleWhite"
        />

Here is a post where someone got it to work. It looks like it requires a registry change.

response.GetResponseStream() should be used to return the response stream. And don't forget to close the Stream and Response objects.

In this line:

fund = fund * (1 + 0.01 * growthRates) + depositPerYear

growthRates is a sequence ([3,4,5,0,3]). You can't multiply that sequence by a float (0.1). It looks like what you wanted to put there was i.

Incidentally, i is not a great name for that variable. Consider something more descriptive, like growthRate or rate.

Easy way that just worked for me:

1. Check if you have a jdk installed (it is usually in "Program Files\Java", if you don't have one, install it.
2. Link it to eclipse. In Preferences --> Java --> Installed JREs remove the JRE installed and add the JDK.

Then the project will detect it and add the new libraries from the JDK. At the end of this process it looks like the screenshot I attach.

if is not a loop structure, so you cannot "break out of it".

You can, however, break out of the foreach by simply calling break. In your example it has the desired effect:

$device = "wanted";
foreach($equipxml as $equip) {
    $current_device = $equip->xpath("name");
    if ( $current_device[0] == $device ) {
        // found a match in the file            
        $nodeid = $equip->id;

        // will leave the foreach loop and also the if statement
        break;
        some_function(); // never reached!
    }
    another_function();  // not executed after match/break
}

Just for completeness for others that stumble upon this question looking for an answer..

break takes an optional argument, which defines how many loop structures it should break. Example:

foreach (array('1','2','3') as $a) {
    echo "$a ";
    foreach (array('3','2','1') as $b) {
        echo "$b ";
        if ($a == $b) { 
            break 2;  // this will break both foreach loops
        }
    }
    echo ". ";  // never reached!
}
echo "!";

Resulting output:

1 3 2 1 !

From SQL database get enum like:

SqlDataReader dr = selectCmd.ExecuteReader();
while (dr.Read()) {
   EnumType et = (EnumType)Enum.Parse(typeof(EnumType), dr.GetString(0));
   ....         
}

const arr = [1, 2, 3];
console.log(`${arr}`)

Non programmatically, you can just open the archive using the 7zip UI to add/remove or extract/replace files without the structure changing. I didn't know it was a problem using other things until now :)

.joins will just joins the tables and brings selected fields in return. if you call associations on joins query result, it will fire database queries again

:includes will eager load the included associations and add them in memory. :includes loads all the included tables attributes. If you call associations on include query result, it will not fire any queries

You need use Stream to send file (archive) in a response, what is more you have to use appropriate Content-type in your response header.

There is an example function that do it:

const fs = require('fs');

// Where fileName is name of the file and response is Node.js Reponse. 
responseFile = (fileName, response) => {
  const filePath =  "/path/to/archive.rar" // or any file format

  // Check if file specified by the filePath exists 
  fs.exists(filePath, function(exists){
      if (exists) {     
        // Content-type is very interesting part that guarantee that
        // Web browser will handle response in an appropriate manner.
        response.writeHead(200, {
          "Content-Type": "application/octet-stream",
          "Content-Disposition": "attachment; filename=" + fileName
        });
        fs.createReadStream(filePath).pipe(response);
      } else {
        response.writeHead(400, {"Content-Type": "text/plain"});
        response.end("ERROR File does not exist");
      }
    });
  }
}

The purpose of the Content-Type field is to describe the data contained in the body fully enough that the receiving user agent can pick an appropriate agent or mechanism to present the data to the user, or otherwise deal with the data in an appropriate manner.

"application/octet-stream" is defined as "arbitrary binary data" in RFC 2046, purpose of this content-type is to be saved to disk - it is what you really need.

"filename=[name of file]" specifies name of file which will be downloaded.

For more information please see this stackoverflow topic.

Looks like you created a separate question. I was answering your other question How to change flat file source using foreach loop container in an SSIS package? with the same answer. Anyway, here it is again.

Create two string data type variables namely DirPath and FilePath. Set the value C:\backup\ to the variable DirPath. Do not set any value to the variable FilePath.

Select the variable FilePath and select F4 to view the properties. Set the EvaluateAsExpression property to True and set the Expression property as @[User::DirPath] + "Source" + (DT_STR, 4, 1252) DATEPART("yy" , GETDATE()) + "-" + RIGHT("0" + (DT_STR, 2, 1252) DATEPART("mm" , GETDATE()), 2) + "-" + RIGHT("0" + (DT_STR, 2, 1252) DATEPART("dd" , GETDATE()), 2)

Besides what other said, a common problem is to declare the types of the same function that is overloaded. Typical case is EventEmitter on() method which will accept multiple kind of listeners. Similar could happen When working with redux actions - and there you use the action type as literal to mark the overloading, In case of EventEmitters, you use the event name literal type:

interface MyEmitter extends EventEmitter {
  on(name:'click', l: ClickListener):void
  on(name:'move', l: MoveListener):void
  on(name:'die', l: DieListener):void
  //and a generic one
  on(name:string, l:(...a:any[])=>any):void
}

type ClickListener = (e:ClickEvent)=>void
type MoveListener = (e:MoveEvent)=>void
... etc

// will type check the correct listener when writing something like:
myEmitter.on('click', e=>...<--- autocompletion

Cached files are indeed stored in /data/data/my_app_package/cache

Make sure to store the files using the following method:

String cacheDir = context.getCacheDir();
File imageFile = new File(cacheDir, "image1.jpg");
FileOutputStream out = new FileOutputStream(imageFile);
out.write(imagebuffer, 0, imagebufferlength);

where imagebuffer[] contains image data in byte format and imagebufferlength is the length of the content to be written to the FileOutputStream.

Now, you may look at DDMS File Explorer or do an "adb shell" and cd to /data/data/my_app_package/cache and do an "ls". You will find the image files you have stored through code in this directory.

Moreover, from Android documentation:

If you'd like to cache some data, rather than store it persistently, you should use getCacheDir() to open a File that represents the internal directory where your application should save temporary cache files.

When the device is low on internal storage space, Android may delete these cache files to recover space. However, you should not rely on the system to clean up these files for you. You should always maintain the cache files yourself and stay within a reasonable limit of space consumed, such as 1MB. When the user uninstalls your application, these files are removed.

If you use tab to indent the code block it will shape the entire block into one line. To avoid this you need to use html ordered list.

1. item 1
2. item 2

Code block

<ol start="3">
  <li>item 3</li>
  <li>item 4</li>
</ol>

re.split() can help a little more then string.split()

import re    
var = "d:\stuff\morestuff\furtherdown\THEFILE.txt"
re.split( r'[\\/]', var )
['d:', 'stuff', 'morestuff', 'furtherdown', 'THEFILE.txt']

If you also want to support Linux and Mac paths, just add filter(None,result), so it will remove the unwanted '' from the split() since their paths starts with '/' or '//'. for example '//mount/...' or '/var/tmp/'

import re    
var = "/var/stuff/morestuff/furtherdown/THEFILE.txt"
result = re.split( r'[\\/]', var )
filter( None, result )
['var', 'stuff', 'morestuff', 'furtherdown', 'THEFILE.txt']

You are probably missing the viewport meta tag in the html head:

 <meta name="viewport" content="width=device-width, initial-scale=1">

Without it the device assumes and sets the viewport to full size.

More info here.

This should do the trick:

SET FOREIGN_KEY_CHECKS=0; DROP TABLE bericht; SET FOREIGN_KEY_CHECKS=1;

As others point out, this is almost never what you want, even though it's whats asked in the question. A more safe solution is to delete the tables depending on bericht before deleting bericht. See CloudyMarble answer on how to do that. I use bash and the method in my post to drop all tables in a database when I don't want to or can't delete and recreate the database itself.

The #1217 error happens when other tables has foreign key constraints to the table you are trying to delete and you are using the InnoDB database engine. This solution temporarily disables checking the restraints and then re-enables them. Read the documentation for more. Be sure to delete foreign key restraints and fields in tables depending on bericht, otherwise you might leave your database in a broken state.

With Dedexer, you can disassemble the .dex file into dalvik bytecode (.ddx).

Decompiling towards Java isn't possible as far as I know.
You can read about dalvik bytecode here.

Constructors don't return a type , just remove the return type which is void in your case. It would run fine then.

You want to create a "Dynamic Web Project". Follow the steps here: Spring MVC Tutorial with Eclipse and Tomcat.

Also, here is the Eclipse documentation for Dynamic Web Projects: http://help.eclipse.org/help32/index.jsp?topic=/org.eclipse.wst.webtools.doc.user/topics/ccwebprj.html

What do I do wrong?

The source code of ToastDisplay is OK (mine is similar and works), but it will only receive something, if it is currently in foreground (you register receiver in onResume). But it can not receive anything if a different activity (in this case SendBroadcast activity) is shown.

Instead you probably want to startActivity ToastDisplay from the first activity?

BroadcastReceiver and Activity make sense in a different use case. In my application I need to receive notifications from a background GPS tracking service and show them in the activity (if the activity is in the foreground).

There is no need to register the receiver in the manifest. It would be even harmful in my use case - my receiver manipulates the UI of the activity and the UI would not be available during onReceive if the activity is not currently shown. Instead I register and unregister the receiver for activity in onResume and onPause as described in BroadcastReceiver documentation:

You can either dynamically register an instance of this class with Context.registerReceiver() or statically publish an implementation through the tag in your AndroidManifest.xml.

Check for any recusive calls for methods. Mainly it is caused when there is recursive call for a method. A simple example is

public static void main(String... args) {
    Main main = new Main();

    main.testMethod(1);
}

public void testMethod(int i) {
    testMethod(i);

    System.out.println(i);
}

Here the System.out.println(i); will be repeatedly pushed to stack when the testMethod is called.

From the threading module documentation

There is a “main thread” object; this corresponds to the initial thread of control in the Python program. It is not a daemon thread.

There is the possibility that “dummy thread objects” are created. These are thread objects corresponding to “alien threads”, which are threads of control started outside the threading module, such as directly from C code. Dummy thread objects have limited functionality; they are always considered alive and daemonic, and cannot be join()ed. They are never deleted, since it is impossible to detect the termination of alien threads.

So, to catch those two cases when you are not interested in keeping a list of the threads you create:

import threading as thrd


def alter_data(data, index):
    data[index] *= 2


data = [0, 2, 6, 20]

for i, value in enumerate(data):
    thrd.Thread(target=alter_data, args=[data, i]).start()

for thread in thrd.enumerate():
    if thread.daemon:
        continue
    try:
        thread.join()
    except RuntimeError as err:
        if 'cannot join current thread' in err.args[0]:
            # catchs main thread
            continue
        else:
            raise

Whereupon:

>>> print(data)
[0, 4, 12, 40]

Hey i have posted a video tutorial on youtube about this, you can check that and you can find here the sample code :

http://myfundatimemachine.blogspot.in/2012/06/database-connection-to-java-application.html

Try

sys.exit("message")

It is like the perl

die("message")

if this is what you are looking for. It terminates the execution of the script even it is called from an imported module / def /function

In bootstrap 4 it is much easier to have a border on the fieldset that blends with the legend. You don't need custom css to achieve it, it can be done like this:

<fieldset class="border p-2">
   <legend  class="w-auto">Your Legend</legend>
</fieldset>

which looks like this:

Log returns are simply the natural log of 1 plus the arithmetic return. So how about this?

df['pct_change'] = df.price.pct_change()
df['log_return'] = np.log(1 + df.pct_change)

Even more concise, utilizing Ximix's suggestion:

df['log_return'] = np.log1p(df.price.pct_change())

Try using ifconfig -a. Look for "inet xxx.xxx.xxx.xxx", that is your IP address

Below is code that I currently use to pull data from a MS SQL Server 2008 into VBA.

In case you were struggling to change linetypes, the following answer should be helpful. (This is an addition to the solution by Andy W.)

We will try to extend the learned pattern:

cols <- c("LINE1"="#f04546","LINE2"="#3591d1","BAR"="#62c76b")
line_types <- c("LINE1"=1,"LINE2"=3)
ggplot(data=data,aes(x=a)) + 
  geom_bar(stat="identity", aes(y=h,fill = "BAR"))+ #green
  geom_line(aes(y=b,group=1, colour="LINE1", linetype="LINE1"),size=0.5) +   #red
  geom_point(aes(y=b, colour="LINE1", fill="LINE1"),size=2) +           #red
  geom_line(aes(y=c,group=1,colour="LINE2", linetype="LINE2"),size=0.5) +   #blue 
  geom_point(aes(y=c,colour="LINE2", fill="LINE2"),size=2) +           #blue
  scale_colour_manual(name="Error Bars",values=cols, 
                  guide = guide_legend(override.aes=aes(fill=NA))) + 
  scale_linetype_manual(values=line_types)+
  scale_fill_manual(name="Bar",values=cols, guide="none") +
  ylab("Symptom severity") + xlab("PHQ-9 symptoms") +
  ylim(0,1.6) +
  theme_bw() +
  theme(axis.title.x = element_text(size = 15, vjust=-.2)) +
  theme(axis.title.y = element_text(size = 15, vjust=0.3))

However, what we get is the following result:

The problem is that the linetype is not merged in the main legend. Note that we did not give any name to the method scale_linetype_manual. The trick which works here is to give it the same name as what you used for naming scale_colour_manual. More specifically, if we change the corresponding line to the following we get the desired result:

scale_linetype_manual(name="Error Bars",values=line_types)

Now, it is easy to change the size of the line with the same idea.

Note that the geom_bar has not colour property anymore. (I did not try to fix this issue.) Also, adding geom_errorbar with colour attribute spoils the result. It would be great if somebody can come up with a better solution which resolves these two issues as well.

Java does both compilation and interpretation,

In Java, programs are not compiled into executable files; they are compiled into bytecode (as discussed earlier), which the JVM (Java Virtual Machine) then interprets / executes at runtime. Java source code is compiled into bytecode when we use the javac compiler. The bytecode gets saved on the disk with the file extension .class.

When the program is to be run, the bytecode is converted the bytecode may be converted, using the just-in-time (JIT) compiler. The result is machine code which is then fed to the memory and is executed.

Javac is the Java Compiler which Compiles Java code into Bytecode. JVM is Java Virtual Machine which Runs/ Interprets/ translates Bytecode into Native Machine Code. In Java though it is considered as an interpreted language, It may use JIT (Just-in-Time) compilation when the bytecode is in the JVM. The JIT compiler reads the bytecodes in many sections (or in full, rarely) and compiles them dynamically into machine code so the program can run faster, and then cached and reused later without needing to be recompiled. So JIT compilation combines the speed of compiled code with the flexibility of interpretation.

An interpreted language is a type of programming language for which most of its implementations execute instructions directly and freely, without previously compiling a program into machine-language instructions. The interpreter executes the program directly, translating each statement into a sequence of one or more subroutines already compiled into machine code.

A compiled language is a programming language whose implementations are typically compilers (translators that generate machine code from source code), and not interpreters (step-by-step executors of source code, where no pre-runtime translation takes place)

In modern programming language implementations like in Java, it is increasingly popular for a platform to provide both options.

For those like me, who have reached this thread because they want to serve an html file from linux terminal or want to view it using a terminal command, use these steps:-

1)If you want to view your html using a browser:-
Navigate to the directory containing the html file
If you have chrome installed, Use:-

google-chrome <filename>.html

                OR
Use:-

firefox <filename>.html

2)If you want to serve html file and view it using a browser
Navigate to the directory containing the html file
And Simply type the following on the Terminal:-

pushd <filename>.html; python3 -m http.server 9999; popd;

Then click the I.P. address 0.0.0.0:9999 OR localhost:9999 (Whatever is the result after executing the above commands). Or type on the terminal :-

firefox 0.0.0.0:9999

Using the second method, anyone else connected to the same network can also view your file by using the URL:- "0.0.0.0:9999"
